[0026] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present invention.

[0027] According to an embodiment of the present invention, an external switch for an automobile door is provided.

[0028] As Figures 1-4 shown, an external switch for an automobile door includes: a housing 5 and a PCBA circuit board 6 disposed in the housing 5. The PCBA circuit board 6 is electrically connected to a tactile switch 11. A waterproof rubber sleeve 4 is provided at the top of the housing 5. The waterproof rubber sleeve 4 sequentially embeds a push rod 2 and a button 1 from the inside to the outside. The bottom end of the push rod 2 is snap-connected to the tactile switch 11, and the button 1 is in contact with the push rod 2.

[0029] A waterproof pad 3 is sleeved at the top of the waterproof rubber sleeve 4, and a base 9 is provided at the bottom of the housing 5.

[0030] Wherein, the base 9 is provided with a through hole 10, and a waterproof breathable membrane 7 is provided in the through hole 10. The waterproof breathable membrane 7 is located between the PCBA circuit board 6 and the base 9.

[0031] In this technical solution, the button 1, the waterproof rubber sleeve 4 and the housing 5 are integrally formed by insert two-color injection molding, so as to achieve a sealing effect; the base 9 and the housing 5 are connected by a hidden buckle, and the PCBA circuit board 6 in the housing 5 is electrically connected to a wire harness assembly 8. The wire harness assembly 8 can be disposed on one side of the base 9, and at the same time, glue filling treatment is performed at the bottom to seal the base 9 and the housing 5 as well as the wire harness assembly 8 and the housing 5.

[0032] In addition, a waterproof breathable membrane 7 is pasted on the base 9. The waterproof breathable membrane 7 only allows air to enter, and can prevent water and dust from entering. The main function of the waterproof breathable membrane 7 is to prevent stuffiness from affecting the performance of the button 1.

[0033] In addition, for the above-mentioned waterproof pad 3, the waterproof pad 3 is pasted on the waterproof rubber sleeve 4 to press and seal the switch with the corresponding structure of the automobile, and enhance the dustproof and waterproof performance of the switch.

[0034] In addition, guide posts 12 are symmetrically provided on both sides inside the housing 5. A groove 13 adapted to the guide posts 12 is provided on one side of the push rod 2, and the groove 13 is movably connected to the guide posts 12. Wherein, a pressure rod 14 is provided at the bottom end of the push rod 2, and the pressure rod 14 is in contact with the tactile switch 11.

[0035] In this technical solution, the push rod 2 slides along the guide post 12 in cooperation with the groove 13. When the button 1 is pressed down, the push rod 2 moves downward, thereby turning on the tactile switch 11 connected to the PCBA circuit board 6, and the circuit is turned on to achieve its function. When the downward pressure on the button 1 is cancelled, the tactile switch 11 rebounds, driving the push rod 2 to move upward, thereby driving the button 1 to move upward, and the button 1 is reset, and the circuit is disconnected and powered off to cancel its function.

[0036] In addition, mounting seats 15 which are symmetrically arranged are respectively provided on both sides of the housing 5.

[0037] In summary, by means of the above technical solution of the present utility model, the following effects can be achieved:

[0038] The housing 5 is embedded outside the car door, and the tactile switch 11 connected to the PCBA circuit board 6 is turned on or off by driving the push rod 2 to slide through the button 1, so as to achieve its switching function. At the same time, the waterproof rubber sleeve 4 at the top of the housing 5 and the waterproof pad 3 are pasted on the waterproof rubber sleeve 4, so that the switch is pressed and sealed with the corresponding structure of the car, realizing the dustproof and waterproof performance of the switch. It not only has a small space occupancy rate, but also has a high dustproof and waterproof level, meeting the market demand for arranging switches outside the car door, and having a wide market application benefit.

[0039] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
