Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of micro switches, in particular to a back door micro switch. Background Art
[0002] A micro switch is a switch with a tiny contact spacing and a snap-action mechanism, a contact mechanism that performs switching actions with a specified stroke and a specified force, covered with a shell, and with a driving rod on the outside. Because the contact spacing of the switch is relatively small, it is called a micro switch, also known as a sensitive switch. The traditional micro switch uses a rebound component made of a softer rubber material in the reset structure. Although it also has good elasticity and can achieve good rebound force, its material texture is easily corroded, so it is easy to age after long-term use. Then its rebound force will weaken and it will not achieve the role it should have. The sensitivity of the entire micro switch will also be reduced, and the button reset sensitivity on the switch will also be affected, and it may even remain in the circuit-on state, causing the entire micro switch to malfunction, and only the use of the vehicle will be hindered.

DETAILED DESCRIPTION
[0024] The following will be combined with the attached embodiment of the present utility model Figure 1-4 , the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example
[0025] A back door micro switch comprises a bottom shell 1, the top of the bottom shell 1 is integrally formed with a snap-on component 2, a bracket 3 is fixedly installed on one side of the top of the bottom shell 1, a rubber reset component 4 is fixedly connected to one side of the bracket 3, a fixing frame 5 is integrally provided on the top of the bracket 3, an extrusion cover 6 is rotatably installed on the inner side of the fixing frame 5, an extrusion contact 7 matched with the rubber reset component 4 is fixedly connected to one side of the inner side of the extrusion cover 6, a spring plate 8 is obliquely provided on the top of one side of the extrusion cover 6, a uniformly distributed spring 9 is fixedly connected to the top of the spring plate 8, and one end of the spring 9 away from the spring plate 8 is fixedly connected to the fixing frame 5, and an annular protrusion 15 is fixedly connected to one side of the top of the bottom shell 1.
[0026] The specific usage process is as follows: First, after the entire micro switch is installed, you can operate the micro switch to work for the user, that is, Figure 1As shown, the entire micro switch is divided into two parts and assembled on the rear glass 18 of the vehicle, and the two parts are respectively on the inner side and the outer side of the rear glass 18 of the vehicle. It should be noted that the part with the shell 17 is installed on the outer side of the rear glass 18 of the vehicle, and the shell 17 is also provided with a notch for the user to press the squeeze cover 6, which provides convenience for the user. During use, the user presses the squeeze cover 6 through the window on the shell 17, and then the squeeze cover 6 will rotate on the fixing frame 5, and the squeeze cover 6 will rotate in the direction of the rubber reset member 4. Since the rubber reset member 4 is made of rubber or other soft materials with resilience, the squeeze contact 7 will squeeze the fixing frame 5 under the drive of the squeeze cover 6. Therefore, under the extrusion of the extrusion contact 7, the rubber reset member 4 will also be deformed accordingly, and as the rubber reset member 4 is deformed, the extrusion contact 7 will continue to enter the interior of the bracket 3 under the drive of the extrusion cover 6 until it presses the switch 12. As the switch 12 is turned on, the circuit on the entire circuit board 11 will be connected to form a path. Specifically, the switch 12 is welded on the circuit board 11 and is electrically connected to the circuit board 11. Then, the switch 12 can be electrically connected to the circuit board 11 and the connecting line 13 to form a complete and unobstructed circuit, ensuring that the user can smoothly transmit the operating instructions when using it, providing convenience for the user, and then the input instructions The command will be transmitted to the corresponding components through the connecting line 13, thereby completing the opening and closing of the back door, providing convenience for the user. It should be noted that when the extrusion cover 6 rotates, the spring plate 8 will also be driven to move. Then, with the movement of the spring plate 8, the multiple springs 9 on the spring plate 8 will be stretched, and the spring 9 will also produce corresponding deformation. After that, after the user releases the pressure on the extrusion cover 6, the rubber reset member 4 will return to its original state under the action of its own elasticity without the extrusion force, thereby also pushing the extrusion cover 6 back to its original position for the next use. At the same time, the extrusion cover 6 has no extrusion force, so there is no pulling force on the spring 9, and then under the elastic force of the spring 9 itself, the spring 9 will also return to its original state, thereby pulling the extrusion cover 6 back to its original position to achieve the resetting of the extrusion cover 6, and then the rubber resetting member 4 will also be restored, and the switch 12 will also be reset when it is turned on, so as to facilitate subsequent use. At the same time, it can also play a role of accurate resetting, ensuring that the micro switch can be accurately opened and closed, providing convenience for the user's work and use. It should be noted that two layers of waterproofing are arranged on the bottom shell 1 and the outer shell 17, which are achieved by using sealing rings. One layer is arranged around the shape of the bottom shell 1 and the outer shell 17, and the other layer is arranged at the connection between the connector 16 and the bottom shell 1, so that the gaps on the entire micro switch can be sealed, thereby improving the sealing of the micro switch, protecting the micro switch, and extending the service life of the micro switch.
[0027] Therefore, a double-return structural design is adopted, and a spring component is added to the original rubber rebound component. When the two are used in coordination, even when the rubber rebound component is aged and the rebound effect is weakened, the spring can still meet the return work of the switch button, so that the micro switch can still be used normally and sensitively, thereby extending the service life of the micro switch and providing convenience for users.

[0029] Specifically, the circuit board 11, the on switch 12 and the connecting wire 13 are arranged such that the on switch 12 is welded on the circuit board 11 and is electrically connected to the circuit board 11. Then, the on switch 12 can be electrically connected to the circuit board 11 and the connecting wire 13 to form a complete and unobstructed circuit, thereby ensuring that the operating instructions are smoothly transmitted when the user is in use, thereby providing convenience for the user.
[0030] The top of the bottom shell 1 is clamped with an outer shell 17 , and clamping strips 14 are fixedly connected to both sides of the bracket 3 . The bracket 3 is clamped on the outer shell 17 via two clamping strips 14 .

[0032] A plug-in connector 16 is plugged into the inner side of the bottom shell 1 and the outer shell 17 , and a shaft rod 19 is plugged into the inner side of the plug-in connector 16 .
[0033] Specifically, the arrangement of the connector 16 and the shaft rod 19, the installation method of the connector 16 and the shell 17 is that the connector 16 is plugged into the bottom shell 1 and the shell 17, and the connector 16 and the shell 17 are distributed on both sides of the vehicle rear glass 18, so that with the cooperation of the shaft rod 19, the entire micro switch can be firmly fixed in the current position, ensuring the stability of the micro switch installation and providing convenience for users.
