Description

Technical Field

[0001] The utility model relates to a switch device, in particular to an external switch for an automobile trunk. Background Art

[0002] An external switch is usually arranged on the tailgate of an automobile trunk. A person standing beside the trunk can directly operate to open the trunk, which is more convenient to use. The external switch of the trunk has requirements for waterproof and dustproof performance. Usually, it needs to be integrally wrapped with soft glue. The adhesion of the paint surface is poor, and it is basically impossible to color, so it cannot be coordinated with the visible color of the automobile tailgate. Therefore, the pressing panel part of the usual external switch of the trunk is installed nearly 90° downward during installation and cannot be directly seen on the surface of the automobile tailgate to avoid affecting the appearance of the automobile tailgate. However, this installation method affects the convenience of switch operation and constitutes a certain limitation to the change of the styling design of the automobile tail. Summary of the Invention

[0003] Aiming at the deficiencies of the prior art, the utility model provides an external switch for an automobile trunk with good waterproof and dustproof performance and can be installed directly visible.

[0004] The utility model includes a shell and a base which are connected in a butted manner. A touch switch and output pins are connected to the built-in circuit board. A push rod that can move up and down is arranged in the shell. The lower end of the push rod is in corresponding pressing contact with the touch switch. A soft closed cover is integrally formed and connected to the upper end of the shell. The upper end of the push rod is located below the soft closed cover. A panel bracket with a pressing panel on its surface is penetratively installed at a visible position on the surface of the automobile tailgate. The surface of the pressing panel is sprayed with paint matching the color of the automobile tailgate. The upper part of the shell is inserted and connected with the panel bracket, and the soft closed cover is adjacent to the pressing panel.

[0005] The structure of the utility model is reasonable. The internal circuit part is completely shielded, and the conduction and cutting-off processes are isolated from the outside world. The waterproof and dustproof performance is very good, ensuring the reliability of use. The pressing panel part can be installed at a directly visible position on the surface of the automobile tailgate and is sprayed with paint matching the color of the automobile tailgate. The overall appearance is coordinated, the switch operation is convenient, and the change of the styling design of the automobile tail is more free.

[0006] The following further illustrates the utility model with reference to the drawings and specific embodiments. Description of the Drawings

[0012] Figure 6 It is a schematic structural view of the installation state of the embodiment. Detailed implementation manners

[0013] As Figures 1 to 4 shown, a base 2 is connected in an opposing manner below the housing 1, and a tactile switch 4 and output pins 5 are connected to the built-in circuit board 3. A push rod 6 that can be displaced up and down is arranged in the housing 1, and the lower end of the push rod 6 is in pressure contact and cooperation with the tactile switch 4. A soft closed cover 7 is integrally formed and connected to the upper end of the housing 1, and the upper end of the push rod 6 is located below the soft closed cover 7. A panel bracket 9 with a pressing panel 8 on its surface is penetratively installed at a visible position on the surface of the vehicle tailgate 12, and the surface of the pressing panel 8 is sprayed with paint matching the color of the vehicle tailgate 12. The upper part of the housing 1 is inserted and connected to the panel bracket 9, and the soft closed cover 7 is adjacent to the pressing panel 8.

[0014] The pressing panel 8 of this embodiment is also soft, as Figure 5 shown, and is integrally formed and connected to the surface of the panel bracket 9. A waterproof ring 10 is padded between the panel bracket 9 and the surface of the vehicle tailgate 12. This can make the external dust and waterproof performance of the switch stronger and prevent dust and water vapor from entering the vehicle tailgate 12 from the outside of the switch. A paint protection film 11 is pasted on the surface of the pressing panel 8 to protect the sprayed paint from cracking and peeling due to environmental factors and the like. In addition, sealant is poured into the gap at the lower part of the base 2 to better seal and protect the internal circuit.

[0015] The state where the switch is actually installed on the surface of the vehicle tailgate 12 is as Figure 6 shown. When in use, an operator presses the pressing panel 8, and the deformed pressing panel 8 pushes the adjacent soft closed cover 7 to deform as well, causing the push rod 6 to displace, pressing the tactile switch 4 to conduct, and the generated signal is transmitted to the corresponding connected wire terminal through the output pins 5, thereby controlling the unlocking of the locking part of the vehicle tailgate 12, and the trunk can be opened.
