Dongguan Teao Damper: The Innovative Guardian of Automotive Charging Ports
In the current era of increasing popularity of new energy vehicles, the convenience, safety, and durability of vehicle charging ports, as the key entry points for vehicles to obtain electrical energy, have garnered increasing attention. Traditional vehicle charging ports have revealed numerous issues during daily use, while the innovative application of Dongguan Teao dampers has presented new opportunities for the optimization of vehicle charging ports.
The drawbacks of traditional car charging ports
Opening and closing impact and noise
When opening and closing the lid of the car charging port, due to the lack of effective cushioning, rapid opening and closing often occurs. When users open the charging port lid, if they apply a slight amount of force, the lid may quickly pop up, which is not only prone to causing a bump on the hand but may also damage the internal connection structure of the charging port due to the instantaneous impact force. When closing the lid, affected by gravity and inertia, the lid will quickly fall back, producing a loud impact sound. This noise is particularly conspicuous in a relatively quiet charging environment, which not only affects the experience of the car owner and surrounding personnel but also, due to long-term frequent impacts, can lead to loosening and damage of the charging port lid.
The waterproof and dustproof performance is affected
The charging port cover, which opens and closes quickly, tends to vibrate when closed, which may cause the originally tightly fitted sealing rubber strip to shift or deform, thereby weakening the waterproof and dustproof capabilities of the charging port. When charging in rainy weather or driving in dusty environments, rainwater and dust may enter the interior of the charging port through gaps, causing corrosion or short circuits to the charging interface and related electronic components, seriously affecting the normal operation of the charging system and even threatening the overall safety of the vehicle.
Insufficient durability
As a frequently used component of new energy vehicles, the charging port experiences significant wear and tear from frequent and rapid opening and closing of its mechanical parts. Traditional charging ports lack buffer protection, making internal components such as rotating shafts and hinges prone to wear, deformation, and other issues under long-term impact, greatly shortening the service life of the charging port. This not only increases the maintenance costs for vehicle owners but also may lead to charging failures at critical moments due to charging port malfunctions, causing great inconvenience to vehicle owners.
Working principle of Dongguan Teao damper
Since its establishment in 2001, Dongguan Teao Electronic Technology Co., Ltd. has been dedicated to the research, development, and production of automotive components such as dampers, accumulating rich experience and advanced technology. The core working mechanism of the dampers produced by the company is to effectively dissipate kinetic energy by providing resistance opposite to the direction of object movement, achieving smooth and gradual motion control.
Taking the rotary damper applied to the car charging port as an example, when the user opens the charging port cover, the structure made of special materials inside the damper and the filled medium such as silicone oil come into play. As the cover rotates, the frictional force generated by the internal structure and the viscous resistance of the silicone oil jointly form an opposing force to the direction of rotation, which gradually slows down the opening speed of the cover and avoids the impact caused by rapid ejection. When closing the charging port cover, the damper can also absorb the kinetic energy of the cover falling back, allowing the cover to return slowly, thus eliminating the noise and component wear problems caused by rapid falling back.
Innovative application forms
External linear damper auxiliary structure
A common application method is to set up an external linear damper auxiliary structure near the car charging port. Taking a new energy vehicle that adopts this structure as an example, its charging port structure includes the charging port body and the cover assembly connected to it. On the side of the charging port near the position of the cover hinge, a damping structure consisting of a cuboid-shaped damper housing and a cylindrical linear damper is installed. The damper housing is equipped with a vertically arranged and top-through cylindrical damper mounting hole, and the linear damper is installed in this hole, with one end of its piston rod facing upwards.
When the user opens the charging port cover, during the rotation process, a specific part of the cover will gradually come into contact with and press down on the top of the piston rod of the linear damper. As the cover continues to rotate, the piston rod slowly moves downwards under the action of the medium inside the damper, and the linear damper exerts an upward reaction force on the cover, effectively reducing the rotation speed of the cover and achieving smooth opening. By reasonably adjusting parameters such as the number and specifications of linear dampers, as well as the installation position of the damper housing, it is possible to adapt to the size, weight, and personalized requirements of different vehicle models regarding the opening force and speed of the cover. For some large new energy SUV models, due to the relatively large and heavy charging port cover, the number of linear dampers can be appropriately increased or a model with greater resistance can be selected to ensure that the cover can be easily and smoothly opened.
Built-in damping gear linkage system
Dongguan Teao damper is also applied to car charging ports in the form of an internal damping gear linkage system. This application is typically seen in some high-end new energy vehicle models or charging port systems with special designs. In such designs, the damping gear serves as a key component of the entire charging port cover transmission system, assuming the important responsibilities of buffering and regulating power transmission.
For example, in some motor-driven systems for electric charging port covers, a damping gear is interconnected with the motor output shaft and the rotational shaft of the cover. When the motor receives a signal to open or close the charging port cover and starts to operate, the power output by the motor is first transmitted to the damping gear. The damping gear, through its unique tooth design and the high-viscosity damping medium filled inside, buffers and adjusts the power transmitted from the motor, making the power delivered to the charging port cover smooth and gentle, thus achieving a slow and uniform opening or closing of the cover. The advantage of this built-in damping gear linkage system lies in its ability to integrate closely with the overall structure of the car charging port, without occupying additional external space, ensuring the simplicity and integrity of the charging port appearance. At the same time, by precisely designing various parameters of the damping gear, such as tooth count, modulus, tooth profile, etc., accurate control over the opening and closing speed of the charging port cover can be achieved. In some luxury new energy vehicle models that have extremely high requirements for overall vehicle quietness, by carefully tuning the damping coefficient of the damping gear, the charging port cover can achieve almost silent effects during the opening and closing process, greatly enhancing the user experience.
Bringing significant advantages
Enhance usage safety and comfort
The application of Dongguan Teao dampers has made the opening and closing of car charging port covers more stable and controllable, effectively avoiding accidental injuries to users' hands caused by the rapid ejection or retraction of the covers. Whether it is during the daily hurried charging process or when operating the charging port in a dimly lit environment, car owners no longer need to worry about their hands being pinched by the rapidly ejected covers. At the same time, the smooth opening and closing process also allows users to feel more fluid and comfortable when operating the charging port, enhancing the overall user experience.
Enhance waterproof and dustproof performance
The damper enables the charging port cover to close slowly and smoothly, reducing vibration during closure. This effectively prevents displacement or deformation of the sealing rubber strip caused by vibration, ensuring good waterproof and dustproof performance of the charging port. This provides reliable protection for the electronic components inside the charging port, reduces the risk of malfunction caused by rainwater or dust intrusion, extends the service life of the charging system, and ensures the safety and stability of vehicle charging.
Extend the service life of the charging port
Frequent rapid opening and closing causes significant wear and tear on the mechanical components of the charging port. The Dongguan Teao damper can absorb and buffer the impact force during the opening and closing process of the charging port cover, significantly reducing friction and wear between internal mechanical components. For example, under the protection of the damper, components such as the hinge and shaft of the charging port cover experience much less wear, thereby extending the overall service life of the charging port. This not only reduces maintenance costs for vehicle owners but also minimizes inconveniences caused by charging port malfunctions, enhancing the reliability of vehicle use.
Enhance the sense of quality of vehicles
In today's fiercely competitive automotive market, details often determine success or failure. Dongguan Teao Dampers enhance the charging port of cars with a smoother and quieter operation experience. This subtle quality improvement is particularly important in high-end models, further enhancing the overall quality and luxury feel of the car, and meeting users' pursuit of high-quality travel. Among some automotive brands that focus on user experience, the application of dampers on charging ports has become one of the important selling points to enhance product competitiveness, attracting more consumers' attention and favor.
The innovative application of Dongguan Teao dampers in automotive charging ports has brought numerous tangible benefits to new energy vehicle users through the detailed optimization of this crucial component. With the vigorous development of the new energy vehicle industry and the continuous improvement of consumers' requirements for vehicle quality, it is believed that more and more automakers will adopt similar innovative technologies to create a safer, more convenient, and more comfortable charging experience for the vast number of car owners
