Detailed Implementation

[0016] The following will refer to the appendix in the embodiments of this utility model. Figure 1-7 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] As shown in the figure, an easily detachable automotive combination switch includes a base 1 and a handle mechanism 2. The handle mechanism 2 includes a handle body 21, a mounting base 22, a contact mounting block 23, and a circuit board 24. The contact mounting block 23 is movably disposed within the mounting base 22, and the handle body 21 is movably disposed on the mounting base 22 and linked with the contact mounting block 23. The base 1 has a mounting groove 11 with a lower opening and a right opening. The mounting base 22 includes an upper seat body 221, a middle seat body 222, and a lower seat body 223. The upper body 221 is engaged with the mounting groove 11 through the right end opening of the mounting groove 11, and the front and rear ends of the upper body 221 are provided with a plurality of first engaging holes 2211. The front and rear ends of the middle body 222 are provided with a plurality of first engaging blocks 2221. The middle body 222 passes into the upper body 221 so that the first engaging blocks 2221 are engaged into the first engaging holes 2211. The contact mounting block 23 is movably disposed on the middle body 222. The lower end of the middle body 222 is provided with a second engaging block 2222. The circuit board 24 is provided with a second... The circuit board 24 is positioned at the lower end of the middle seat 222, opposite to the contact mounting block 23, so that the second locking block 2222 is engaged in the second locking hole 241. The upper seat 221 has several third locking holes 2212 at its left end, and the lower seat 223 has several third locking blocks 2231 formed at its left end. The lower seat 223 is positioned at the lower end of the upper seat 221, covering the middle seat 222, so that the third locking blocks 2231 are engaged in the third locking holes 2212. The lower seat 223 has a through-hole that extends upward through the circuit board 24 and... The middle seat 222 is screwed onto the upper seat 221 by bolts. Through the above structure, the middle seat 222 is detachably connected to the upper seat through the cooperation of the first snap-fit ​​block 2221 and the first snap-fit ​​hole 2211. The circuit board 24 is detachably connected to the lower end of the middle seat 222 through the cooperation of the second snap-fit ​​block 2222 and the second snap-fit ​​hole 241. The lower seat 223 is detachably connected to the upper seat 221 through the matching of the third snap-fit ​​block 2231 and the third snap-fit ​​hole 2212, thus limiting the circuit board 24 to the lower end of the middle seat 222.

[0018] Specifically, the structure of the upper seat 221 engaging with the base 1 includes: a plurality of first insertion blocks 2213 formed on the left end of the upper seat 221; a fourth engaging block 2214 formed on the upper end of the upper seat 221; a first abutting block 2215 formed at each of the front and rear ends of the upper seat 221; a plurality of first insertion holes 12 opened on the left inner wall of the mounting groove 11; a fourth engaging hole 13 opened on the upper inner wall of the mounting groove 11; and two second abutting blocks 14 formed on the base 1, respectively located on the front and rear sides of the opening at the right end of the mounting groove 11. The connecting block 2213 is inserted into the first insertion hole 12, the first abutting block 2215 abuts against the upper end of the second abutting block 14, and the fourth locking block 2214 is locked into the fourth locking hole 13. Through the above structure, the fourth locking block 2214 and the fourth locking hole 13 cooperate to limit the displacement of the upper seat 221 relative to the base 1 in the left and right direction. The cooperation between the first abutting plate and the first insertion block 2213 and the first insertion hole 12 limits the displacement of the upper seat 221 relative to the base 1 in the up and down direction, so as to realize the detachable connection between the upper seat 221 and the base 1.

[0019] Specifically, the contact mounting block 23 is movably disposed within the mounting base 22: the lower end of the middle base 222 is provided with a movable groove 2224, and the contact mounting block 23 is placed in the movable groove 2224, so that the contact mounting base 22 is located above the circuit board 24 and cooperates with the limiting plate.

[0020] Specifically, the handle 21 is movably mounted on the mounting base 22: two symmetrical rotating posts 211 are formed on the handle 21, and a rotating hole 25 is opened on the upper base 221 and the middle base 222 respectively. The end of the handle 21 passes into the upper base 221 and is located above the middle base 222 so that the rotating posts 211 are inserted into the rotating holes 25. A transmission member 212 is movably connected to the handle 21, passing through the middle base 222 and abutting against the contact plate mounting block 23.

[0021] In the above structure, after the upper seat 221 is engaged in the mounting groove 11, the lower seat 223 is located outside the mounting groove 11. When it is necessary to inspect the fit between the contact mounting block 223 and the circuit board 24, unscrew the bolts that pass through the lower seat 223 and are screwed onto the upper seat 221. Then, push the third locking block 2231 out from the third locking hole 2212, so that the lower seat 223 can be removed from the upper seat 221 to expose the circuit board 24. Then, push the second locking block 2222 out from the second locking hole 241, so that the circuit board 24 can be removed from the upper seat 221 to expose the contact mounting block 23. At this time, the fit between the contact mounting block 23 and the circuit board 24 can be inspected and the position of the contact engagement between the contact mounting block 23 and the contact on the circuit board 24 can be adjusted to ensure that the contact on the contact mounting block 22 and the circuit board 24 are properly aligned. 4. The precise matching enables the various functions of the automotive combination switch. Similarly, the detachable connection between the middle seat 222 and the upper seat 221 allows the middle seat 222 to be easily removed from the upper seat 221, and the rotating post 211 to be removed from the rotating hole 25, thus removing the handle 21. In this way, the connection between the various components constituting the handle mechanism 2 is set as a detachable connection, which facilitates the individual disassembly of each component without having to remove the handle mechanism 2 from the base 1 as a whole. This allows maintenance personnel to easily inspect or replace the corresponding components as needed, thereby facilitating maintenance operations. The detachable connection between the upper seat 221 and the base 1 is achieved by pushing the fourth locking block 2214 out of the locking hole, which allows the handle mechanism 2 to be removed from the base 1 as a whole, making it convenient for maintenance personnel to inspect the automotive combination switch as needed.

[0022] Furthermore, based on the above structure, the upper seat 221 has a guide protrusion 2216 formed at both its front and rear ends, and the mounting groove 11 has a guide groove 15 on its front and rear inner walls. The guide protrusion 2216 is inserted into the guide groove 15. When the upper seat 221 is engaged with the mounting groove 11 through the right end opening, the guide protrusion 2216 inserted into the guide groove 15 guides the movement of the upper seat 221 within the mounting groove 11, allowing the first insertion block 2213 to be accurately inserted. The first insertion hole 12 is inserted into the fourth insertion hole 13, so that the fourth locking block 2214 can be accurately inserted into the fourth locking hole 13, and the first abutting block 2215 can accurately abut against the second abutting block 14. This facilitates the operation of installing the upper seat 221 in the mounting groove 11, which is to say, facilitates the operation of installing the handle mechanism 2 on the base 1. At the same time, the guide protrusion 2216 cooperates with the guide groove 15 to limit the vertical displacement of the upper seat 221 relative to the base 1, thereby enhancing the stability of the handle mechanism 2 installed on the base 1.

[0023] Furthermore, based on the above structure, the lower end of the first abutment block 2215 is formed with a first limiting tooth 2217 extending in the front-back direction, and the upper end of the second abutment block 14 is formed with a second limiting tooth 16 extending in the left-right direction. The first limiting tooth 2217 and the second limiting tooth 16 abut against each other. When the upper seat 221 is engaged in the mounting groove 11, the mutually perpendicular first limiting tooth 2217 and the second limiting tooth 16 abut against each other and bite into each other, thereby limiting the displacement of the upper seat 221 relative to the base 1 in the left-right direction, thereby strengthening the stability of the handle mechanism 2 mounted on the base 1.

[0024] Furthermore, based on the above structure, the front and rear ends of the middle seat 222 are provided with a plurality of positioning blocks 2223, and the front and rear ends of the upper seat 221 are provided with a plurality of positioning grooves 2218. The positioning blocks 2223 are inserted into the positioning grooves 2218. When the middle seat 222 is inserted into the upper seat 221 and the first snap-fit ​​block 2221 is snapped into the first snap-fit ​​hole 2211, the positioning blocks 2223 are inserted into the positioning grooves 2218 through the openings of the positioning grooves 2218 and slide within the positioning grooves 2218. The cooperation between the positioning blocks 2223 and the positioning grooves 2218 provides a positioning function for the installation of the middle seat 222 on the upper seat 221, so that the middle seat 222 can be accurately installed in the upper seat 221. In addition, the cooperation between the positioning blocks 2223 and the positioning grooves 2218 limits the displacement of the middle seat 222 relative to the upper seat 221, thereby strengthening the stability of the middle seat 222 installed on the upper seat.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
