Description

Technical Field

[0001] This invention relates to the field of automotive interior parts technology, and in particular to a light-emitting automotive door handle assembly structure. Background Technology

[0002] Door handles are increasingly used in the automotive industry. Hidden door handles typically include a locked state and an open state. When locked, the outer surface of the door handle is flush with the outer surface of the car door to achieve a smooth car body surface. When open, the door handle pops out from the car door at least partially, and the user can open or close the car door by holding the door handle.

[0003] In addition to opening and closing the car door, the door handle is also an important exterior component of the car body. To enhance the car body's aesthetics and design, lighting components are added to the door handle. In the existing technology, light guide plates and other structures are usually set at the light source of the lighting components to improve the light perception, but this increases the number of parts and production costs, which is not conducive to making the door handle thinner and lighter.

[0004] The prior art (CN203808672U) describes a luminous car door handle, which includes a housing, a spring, a pin, an LED light, a shock-absorbing pad, and a handle. The housing has a base for fixing it to the car door. The handle has a connecting part on its inner rear end. The housing has a connecting seat corresponding to the connecting part. The connecting part and the connecting seat are rotatably connected by a pin. A spring is sleeved on the pin. The housing has an LED light. Incorporating an LED light into the door handle provides both illumination and aesthetics, meeting the diverse needs of different consumers for the car interior and increasing interaction between the owner and the car.

[0005] However, in the event of a vehicle collision, battery depletion, burnt wiring, or fire causing a short circuit, the electronic door locks will fail directly, leaving the trapped person unable to escape. This is especially true when the vehicle is on fire, which poses a very high risk. In such situations, it is essential to be able to quickly locate the emergency handle and open the door in time. Summary of the Invention

[0006] The purpose of this invention is to provide a light-emitting car door handle assembly structure, which solves the problem that the light-emitting structure of car door handles uses light to indicate the location of the door handle to the occupants in an emergency, so as to open the car door in time and improve the safety of the occupants in the event of an emergency.

[0007] The technical solution adopted by the present invention to solve its technical problem is: a light-emitting car door handle assembly structure, including a handle mounting housing structure, a car door control switch structure disposed in the handle mounting housing structure, and an emergency handle structure disposed in the handle mounting housing structure. The handle mounting housing structure includes an upper panel structure and a mounting end body structure disposed at the lower end of the upper panel structure. The upper panel structure includes a recessed panel body, an extension mating hole for the car door control switch structure disposed in the panel body, and a C-shaped emergency handle structure mounting end disposed at the end of the panel body. The emergency handle structure includes an emergency handle body disposed in the emergency handle structure mounting end and having a light-emitting cavity, a handle body connecting seat connected to the emergency handle body, a handle end cover connected to the handle body connecting seat, a mounting spring assembly disposed between the handle body connecting seat and the handle end cover, and a light-emitting structure disposed in the emergency handle body.

[0008] The aforementioned spring-loaded mounting assembly includes a pivot pin, a torsion spring, a buffer pin, a second pivot pin, a damper, and screws.

[0009] The light-emitting structure includes a light-emitting element disposed in the emergency handle body, a light-emitting element connecting joint, and a PC light-transmitting plate disposed in the upper display surface of the emergency handle body and having a light-transmitting marking body.

[0010] The light-emitting element is fixed by an internal clip in the light-emitting cavity of the emergency handle body.

[0011] The light-emitting structure includes a PCB light-emitting board disposed in the light-emitting cavity, a PCB wire harness connected to the PCB light-emitting board, and a PCB connector.

[0012] The light-emitting cavity is equipped with a contour clamp for fixing the PCB light-emitting board.

[0013] The beneficial effects of this invention are: the invention has a simple structure and sets multiple light sources in the door handle assembly structure to prompt the people inside the vehicle to quickly find the location of the door handle in an emergency so as to open the car door in time, thereby improving the safety of the people inside the car in emergency situations and meeting the diverse needs of different consumers for the car interior.

[0026] The terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end" used in the application text to indicate orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings. They are used solely for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly.
