Description

Technical Field

[0001] The utility model relates to the technical field of door handle key switches, and more specifically to a semi-hidden door handle switch for an automobile. Background Art

[0002] The car door handle is the part that you hold when opening the car door. The car door handle, also known as the door lock or door buckle, is the part that the driver and passengers hold when entering the vehicle. It is divided into inner door handles and outer door handles. Most car models use horizontal bar outer pull door handles. This design is ergonomic and can open the door with the least force and the most comfortable way. With the improvement of people's quality of life and the continuous development of electronic technology, people are using more and more electronic auxiliary devices with efficient and convenient functions. In addition to having higher and higher requirements for the performance of these auxiliary devices, people have also put forward more requirements on the use time of these auxiliary devices. At present, the door handle push button switches on the market are assembled together with the door handle by superimposing the ordinary push button shell and rubber (soft glue) installation.

[0003] In the actual use of door handles, semi-hidden door handles are the most common type today. Semi-hidden door handles are designed on the door body, but are partially or completely covered by the door exterior and are not directly exposed. Semi-hidden door handles are not only practical, but also have a certain degree of safety. They can make the body lines smoother, reduce the drag coefficient, and improve aerodynamic performance. This design is becoming more and more common in modern cars, which not only improves the aesthetics but also retains practicality. However, in the use of semi-hidden door handles, gaps will gradually appear in the outer shell during long-term use, which will cause fine dust to enter the inside of the outer shell. Since a structure that triggers the microswitch is provided inside the outer shell, dust will enter the microswitch, thereby affecting the sensitivity of the microswitch. Therefore, in order to solve the above problems, the existence of a semi-hidden door handle switch for automobiles is crucial. Utility Model Content

[0004] The main technical problem solved by the utility model is to provide a semi-hidden door handle switch for an automobile, which can solve the problems raised by the above-mentioned background technology.

[0005] To solve the above technical problems, according to one aspect of the utility model, more specifically, a semi-hidden door handle switch for a car comprises a main body, a pressing plate is snap-connected on the top of the main body, limiting mechanisms are fixedly arranged on both sides of the top of the pressing plate inside the main body, the pressing plate moves up and down on the top of the main body through the limiting mechanisms, a shell is fixedly sleeved on the top of the pressing plate, a PCBA board is fixedly arranged inside the main body, two micro switches are fixedly arranged on the top of the PCBA board, a communication harness is fixedly connected to one side of the main body, one side of the communication harness is electrically connected to the PCBA board, pressure blocks are fixedly arranged on the bottom of the pressing plate above the two micro switches, and sealing mechanisms are tightly sleeved on the outsides of the two pressure blocks.

[0006] Furthermore, the sealing mechanism includes a rubber sleeve tightly mounted on the outside of the pressure block, sealing rings are fixedly arranged on the upper and lower sides of the rubber sleeve, and the opposite sides of the two sealing rings are tightly fitted with the pressing plate and the main body respectively, and a spring is movably arranged on the outside of the rubber sleeve, and both ends of the spring are fixedly connected to the two sealing rings respectively.

[0007] Furthermore, the limiting mechanism includes first clamping blocks fixedly arranged on both sides of the main body, and second clamping blocks are fixedly arranged at the two first clamping blocks at the bottom of the shell, and the second clamping blocks cooperate with the first clamping blocks to limit the shell.

[0008] Furthermore, a truncated cone groove is formed at the bottom of the rubber sleeve on the outside of the micro switch, and a smooth surface is fixedly provided inside the truncated cone groove.

[0009] Furthermore, an inner concave surface is fixedly provided on the outer side of the rubber sleeve, and the inner concave surface is recessed toward the pressing block.

[0010] Furthermore, a pressing plate is arranged on the outer side of the shell, and glue is applied on the inner side of the pressing plate and is fixedly connected to the shell by the glue.

[0011] The beneficial effects of the semi-hidden door handle switch of the utility model are as follows:

[0012] By setting a sealing mechanism, when in use, the pressing plate drives the pressing block to touch the micro switch by pressing the housing. In this process, the sealing mechanism is wrapped around the outside of the pressing block to seal the space between the pressing block and the micro switch, thereby effectively preventing dust from entering the key structure. At the same time, by setting a spring, a rubber sleeve and a sealing ring, the softness and sealing of the rubber sleeve are utilized to make the pressing smoother and achieve sealing at the same time. The spring squeezes the sealing ring to fit closely with the main body and the pressing plate to further enhance the sealing, and at the same time, it helps to reset the structure, effectively improving the practicality of the structure.

[0013] By setting a limit mechanism, the position of the pressing plate is limited and at the same time, the pressing plate has a certain upward and downward movable space on the top of the main body, so that the smoothness of pressing is achieved while assembling and disassembling are convenient. By setting a truncated cone groove, the micro switch is straightened during use so that it is aligned with the pressing block. By setting an inner concave surface, when the rubber sleeve is deformed by pressing, it can be tightly wrapped around the outside of the pressing block and cooperate with the truncated cone groove to improve the accuracy of pressing. By setting the pressing plate, the comfort during use is effectively improved. BRIEF DESCRIPTION OF THE DRAWINGS
