Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model. Therefore, the following detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the present utility model claimed, but merely represents the selected embodiments of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0022] From Figures 1 to 4As shown in the figure, an embodiment of the present utility model provides an automotive door lock triggering device, which includes a triggering device body 1 and a door lock system 2. The body 1 and the door lock system 2 are electrically connected. The body 1 includes a base 3, an inner housing 4, a static contact base 5, a moving contact base 6, a return spring 7, a protective kit 8, a button 9 and a cover 10. The inner housing 4 is installed on the base 3. The static contact base 5 and the moving contact base 6 are arranged in the inner cavity 11 of the inner housing 4. One end of the moving contact base 6 away from the static contact base 5 extends out from the top opening of the inner housing 4. The return spring 7 is arranged between the static contact base 5 and the moving contact base 6. As an implementation manner, the bottom end of the contact base 6 is provided with a groove to install the return spring 7. The protective kit 8 is connected and arranged between the moving contact base 6 and the static contact base 5. The bottom end of the button 9 abuts against the top end of the moving contact base 6. The cover 10 is arranged outside the button 9. The pressing end of the button 9 extends out from the slot of the cover 10. By arranging the return spring 7 between the static contact base 5 and the moving contact base 6, the connection ends of the two can maintain a distance when not affected by external forces under normal conditions, and at the same time resist the button 9, so that its pressing end extends out from the slot and has an outward tendency. When the button 9 is pressed to push the moving contact base 6 to compress the return spring 7, the connection end of the moving contact base 6 abuts against the connection end of the static contact base 5, and the electrical signal is triggered, and the electrical signal is transmitted from the static contact base 5 to the door lock system 2 through the connecting wire 12, so that the door lock system 2 can unlock or lock, and then the door can be opened and closed through the outer handle 13. The specific circuit is a conventional circuit and will not be elaborated here. Among them, the button 9 has a structure with a protruding pressing end. The outer side wall of the pressing end is tightly attached to the inner side wall of the slot, and the bottom end is limited and designed inside the cover 10 to reduce the probability of external dust, sand and mud water entering the interior. Further, the base 3 includes an installation groove 14. The outer peripheral wall of the inner housing 4 is tightly attached to the inner side wall of the installation groove 14. At the same time, the outer side wall of the static contact base 5 is also tightly attached to the inner side wall of the inner cavity 11. By connecting and arranging the protective kit 8 between the moving contact base 6 and the static contact base 5, a sealed cavity is formed between the moving contact base 6 and the static contact base 5, so as to realize the moisture-proof and dust-proof functions of the connection end circuit.

[0023] Further, a limiting platform 15 is radially and outwardly extended at the top end of the inner housing 4. A sealing member 16 is arranged between the limiting platform 15 and the notch end of the installation groove 14. In this embodiment, the sealing member 16 is an O-ring, so as to further seal the inside of the installation groove 14, which has the functions of waterproof and dust-proof, and further ensure that the internal electronic components can be not affected by the external environment, so that the triggering device body 1 can operate effectively in harsh environments such as mud and dust.

[0024] As a preferred embodiment, the body 1 further includes a guiding seat 17. A guiding groove 18 is provided on the static contact base 5, and the guiding seat 17 is slidably connected to the guiding groove 18. One end of the protective kit 8 is abutted against the guiding seat 17, and the other end is abutted against the moving contact base 6. By providing the guiding seat 17 that can move relative to the static contact base 5 and is better adapted, the tightness between structures can be strengthened. Combined with the protruding structure at the bottom end of the moving contact base 6, the moving contact base 6 is limited in the radial direction, so that the connection of the connection end can be more stable. The guiding seat 17 can also be better used for connecting and installing the protective kit 8.

[0025] Preferably, the protective kit 8 is a rubber sleeve, including an upper connecting portion 19, a lower connecting portion 20, and an elastic portion 21 provided between the upper connecting portion 19 and the lower connecting portion 20. Due to the compact internal space, the lower connecting portion 20 is abutted against the guiding seat 17, and the upper connecting portion 19 is abutted against the bottom side of the moving contact base 6. As an embodiment, an annular groove adapted to the upper connecting portion 19 can be provided on the bottom side of the moving contact base 6, and the lower connecting portion 20 abuts against the end platform on the guiding seat 17, which can facilitate the tight abutting connection between the upper connecting portion 19 and the lower connecting portion 20. Wherein, the diameter of the elastic portion 21 gradually increases from one end close to the upper connecting portion 19 to the other end. Thus, when the moving contact base 6 is forced to approach the static contact base 5, the elastic portion 21 of the protective kit 8 can be deformed, so that the moving contact base 6 can still move for connection, and the connection state between the upper connecting portion 19 and the lower connecting portion 20 remains unchanged. Thereby, the interior can be enclosed to ensure that it is not affected by the external environment, achieving waterproof and dustproof.

[0026] As an embodiment, an LED lamp 22 is provided on the static contact base 5. The circuit of the LED lamp 22 is electrically connected to the door lock system 2. The state of the door lock system 2 can be indicated by the LED lamp 22, such as three states of unlocking, locking, and system failure, and three colors of lights are used for indication, which is convenient for users to distinguish. Among them, the moving contact base 6 and the button 9 are made of light-guiding materials, and the LED lamp 22 can project an indicating light ring on the button 9 for users to observe and identify.

[0027] Preferably, the pressing end of the button 9 is concave. During operation, the finger can be automatically centered for pressing, with a good feel and obvious pressing touch. Combined with the profile design of the return spring 7 and the anti-slip kit, the pressing process has an obvious stroke, and even if the operator wears gloves, there will be an obvious operation feel.

[0028] Preferably, an annular texture is provided on the pressing end of the button 9. By providing the annular texture, the touch and anti-slip effect can be improved, so that the operator can effectively press the button 9 to trigger the door lock system 2 even in harsh environments such as wearing gloves and the environment with muddy water.

[0029] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
