Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile outer door handle, concretely is a car outer door handle with waterproof structure. BACKGROUND

[0002] As one of the key components of the automobile body, the outer door handle is the primary interface for the driver and passengers to interact with the vehicle. Since the birth of automobiles, the design and function of the outer door handle have been evolving. Early outer door handles were relatively simple in structure, mainly focusing on meeting the basic function of opening the door. Typically, they were designed with mechanical linkages, which were manually pulled to drive a series of mechanical structures, achieving the unlocking and opening of the door. With the development of the automotive industry, while ensuring functionality, the outer door handle began to focus on aesthetics and ergonomic design to enhance user experience. The material has gradually changed from single metal to multiple composite materials to meet the needs of lightweight and cost control.

[0003] In the context of the booming development of new energy vehicles, electronic door handles have emerged and gradually become one of the mainstream configurations of new energy vehicles. Compared with traditional mechanical door handles, electronic door handles have many significant advantages. First, in terms of appearance design, electronic door handles can achieve perfect integration with the vehicle body. When the vehicle is in a locked state, the handle is usually hidden on the surface of the vehicle body, making the vehicle body lines more smooth, greatly reducing the vehicle's drag coefficient. This not only enhances the appearance of the vehicle, but also improves the vehicle's range to some extent, which is particularly important for new energy vehicles. For example, the hidden electronic door handle design of some new energy vehicle models has become a highlight of the vehicle's appearance, attracting the attention of many consumers. Second, electronic door handles perform well in terms of intelligence and convenience. By connecting with the vehicle's intelligent system, it can achieve various unlocking methods such as induction unlocking, Bluetooth unlocking, and mobile phone APP remote unlocking. When the owner approaches the vehicle with the key, the door handle will automatically pop up without the need to manually search and pull the handle, truly realizing "touchless" door opening and providing users with a more convenient and efficient user experience. This intelligent design also meets the current consumer's pursuit of technology and convenient life. Third, electronic door handles also have better security. They can work closely with the vehicle's anti-theft system, using various sensors and intelligent algorithms to monitor the status of the door and the surrounding environment in real time, effectively preventing the door from being opened illegally. At the same time, some high-end electronic door handles are also equipped with automatic unlocking function in the event of a collision, which can quickly and automatically unlock the door to facilitate rescue personnel to provide additional protection for the life safety of the driver and passengers.

[0004] Although electronic door handles have many advantages, they also face a problem that cannot be ignored - water damage. Since electronic door handles have a large number of electronic components and delicate mechanical structures integrated inside, once water enters, it can cause short circuits, corrosion and other failures, resulting in the door handle not working properly. In daily use, vehicles may encounter various adverse weather conditions such as heavy rain, car washing, etc., which increases the risk of water entering the electronic door handle. When water enters the handle, electronic components can be damaged due to short circuits, resulting in problems such as loss of induction, inability to unlock or automatic ejection. In addition, water can also accelerate the corrosion of metal parts, affecting the normal operation of the mechanical structure, further shortening the service life of the door handle. Once the electronic door handle is damaged due to water, the repair cost is usually high. Not only do you need to replace damaged electronic components and mechanical parts, but you may also need to perform complex programming and debugging, which not only puts a financial burden on the owner, but also affects the normal use of the vehicle. Therefore, how to improve the waterproof performance of electronic door handles has become a problem that automobile manufacturers and related researchers need to solve.

[0005] In summary, from the traditional mechanical form to the electronic form of today's outside door handle, great progress has been made in functionality, aesthetics and intelligence, but at the same time it also faces the key technical problem of waterproofing. Solving the waterproof problem of electronic door handles is of great significance to improving the overall quality of new energy vehicles and user satisfaction. Practical new type content
