The process of disassembling the screws is cumbersome, which greatly increases the time required for steering wheel repair and disassembly.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a modular combined automotive steering wheel electronic switch, including a disc body, a protective shell installed on the front side of the outer wall of the disc body, a quick-release mechanism installed on the rear side of the outer wall of the protective shell for quick disassembly, and multiple heat dissipation mechanisms installed at equal intervals on the top of the inner wall of the protective shell for ventilation and heat dissipation; the quick-release mechanism includes an elongated plate installed on the rear side of the outer wall of the protective shell, multiple racks fixedly connected at equal intervals on the rear side of the outer wall of the elongated plate, a mounting base installed on the rear side of the outer wall of the disc body, a hollow block fixedly connected to the rear side of the outer wall of the mounting base, a rotating short column rotatably connected to the inner wall of the hollow block, a gear fixedly connected to the outer wall of the rotating short column, support short plates fixedly connected to the left and right sides of the bottom of the hollow block, a fixing short rod installed in the middle of the adjacent side of the outer wall of the support short plate, a spring fixedly connected to the outer wall of the fixing short rod, and multiple positioning grooves equidistantly formed around the outer wall of the rotating short column.

[0006] As a further description of the above technical solution:

[0007] The heat dissipation mechanism includes fan blades, which are equidistantly installed on the top of the inner wall of the protective shell. A rotating column is fixedly connected to the middle of each fan blade, and a drive assembly is installed on the top of the inner wall of the protective shell.

[0008] As a further description of the above technical solution:

[0009] The drive assembly includes a motor, which is mounted on the top of the inner wall of the protective shell. A worm gear is fixedly connected to the output end of the motor, and worm wheels are fixedly connected to the outer walls of the rotating column. A drive battery is installed inside the protective shell.

[0010] As a further description of the above technical solution:

[0011] The worm gear meshes with the worm wheel, and the top of the motor is fixedly connected to the top of the inner wall of the protective shell.

[0012] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, by the operator pulling the short rod, the spring is compressed, causing the short rod to disengage from the positioning groove, releasing the gear lock, and pulling the protective shell to drive the rack to move and mesh with the gear. The gear is rotated clockwise until the rack disengages from the hollow block, thus achieving quick disassembly.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 4 , Figure 5 and Figure 6This utility model provides an embodiment of a modular combined electronic switch for a car steering wheel, including a steering wheel body 1. A protective shell 7 is installed on the front side of the outer wall of the steering wheel body 1, and a quick-release mechanism 2 is installed on the rear side of the outer wall of the protective shell 7 for quick disassembly. Multiple heat dissipation mechanisms 3 are equidistantly installed on the top of the inner wall of the protective shell 7 for ventilation and heat dissipation. The quick-release mechanism 2 includes an elongated plate 201, which is installed on the rear side of the outer wall of the protective shell 7. Multiple racks 206 are equidistantly fixedly connected to the rear side of the outer wall of the elongated plate 201. A mounting base 8 is installed on the rear side of the outer wall of the steering wheel body 1, and a hollow block 202 is fixedly connected to the rear side of the outer wall of the mounting base 8. A rotating short column 203 is rotatably connected to the inner wall of the hollow block 202, and the outer wall of the rotating short column 203 is fixedly connected to the inner wall of the hollow block 202. A gear 204 is fixedly connected. Support plates 207 are fixedly connected to the bottom left and right sides of the hollow block 202. Fixed short rods 208 are installed in the middle of the adjacent side of the outer wall of the support short plate 207. Springs 209 are fixedly connected to the outer wall of the fixed short rods 208. Multiple positioning grooves 205 are equidistantly opened around the outer wall of the rotating short column 203. The worm 3033 is meshed with the worm wheel 3032. The rotation of the worm 3033 can drive the meshed worm wheel 3032 to rotate synchronously. The top of the motor 3031 is fixedly connected to the top of the inner wall of the protective shell 7. The top of the rotating column 302 is rotatably connected to the top of the inner wall of the protective shell 7. The rotating column 302 plays the role of supporting rotation. The top of the drive battery 3034 is fixedly connected to the top of the inner wall of the protective shell 7.

[0035] Specifically, the operator simultaneously pulls the fixed short rods 208 to both sides, compressing the springs 209 to retract, causing the fixed short rods 208 to disengage from the positioning grooves 205 on the outer wall of the rotating short column 203, releasing the lock on the gear 204. The protective shell 7 is then pulled axially backward, causing the elongated plate 201 and rack 206 to move synchronously. The rack 206 meshes with the gear 204, driving the gear 204 to rotate clockwise until the rack 206 completely disengages from the hollow block 202, completing the disassembly of the protective shell 7. When installation is required, the rack 206 on the rear side of the protective shell 7 is aligned with the opening in the hollow block 202, and the protective shell 7 is pushed forward. The rack 206 meshes with the gear 204 again, driving the gear 204 to rotate counterclockwise, and the rack 206 gradually penetrates into the hollow block 202. When the rack 206 is fully inserted, the positioning groove 205 on the rotating short column 203 realigns with the position of the fixed short rod 208. The spring 209 releases its elastic potential energy, pushing the fixed short rod 208 back to its original position, causing its end to re-engage in the positioning groove 205, locking the position of the gear 204, and preventing the rack 206 from dislodging. The worm 3033 meshes with the worm wheel 3032. The rotation of the worm 3033 drives the meshing worm wheel 3032 to rotate synchronously. The top of the motor 3031 is fixedly connected to the top of the inner wall of the protective shell 7. The top of the rotating column 302 is rotatably connected to the top of the inner wall of the protective shell 7. The rotating column 302 supports the rotation. The top of the drive battery 3034 is fixedly connected to the top of the inner wall of the protective shell 7.

A rotating column 302 is fixedly connected to the center of each fan blade 301. A drive assembly 303 is mounted on the top of the inner wall of the protective shell 7. The drive assembly 303 includes a motor 3031, which is mounted on the top of the inner wall of the protective shell 7. A worm gear 3033 is fixedly connected to the output end of the motor 3031. Worm wheels 3032 are fixedly connected to the outer walls of the rotating columns 302. A drive battery 3034 is installed inside the protective shell 7. 34 can provide power to motor 3031 to ensure that motor 3031 can work normally. An indicator light 5 is installed on the upper front side of the outer wall of the disc body 1. The shell of the indicator light 5 is made of scratch-resistant transparent engineering plastic material and integrates a multi-color light-emitting module inside. It can correspond to various working states through different colors and flashing frequencies. Turn signal buttons 4 are installed on the left and right sides of the front end of the outer wall of the disc body 1. The turn signal buttons 4 can realize the function of controlling the flashing and prompting of the turn signal.

[0037] Specifically, the motor 3031 is powered by the drive battery 3034, which then starts the output shaft of the motor 3031 to drive the worm gear 3033 to rotate and mesh with the worm wheel 3032 at the bottom of each rotating column 302. The worm wheel 3032 drives the fan blade 301 to rotate through the rotating column 302, and pushes air out of the protective shell 7 during rotation, forming a forced convection cooling cycle. The drive battery 3034 is installed inside the protective shell 7. The drive battery 3034 can power the motor 3031 to ensure that the motor 3031 can work normally. An indicator light 5 is installed on the upper front side of the outer wall of the disc body 1. The shell of the indicator light 5 is made of scratch-resistant transparent engineering plastic material and integrates a multi-color light-emitting module inside.

Turn signal buttons 4 are installed on the left and right sides of the front end of the outer wall of the disc body 1. The turn signal buttons 4 can realize the function of controlling the flashing and indication of the turn signal.

[0038] Reference Figure 1 , Figure 2 and Figure 5 The bottom of the protective shell 7 is equipped with a ventilation filter 6, which serves to ventilate and intercept external impurities. The outer wall of the ventilation filter 6 is fixedly connected to the inside of the protective shell 7. The gear 204 meshes with the rack 206. The fixing rod 208 engages with the positioning groove 205. By inserting the fixing rod 208 into the positioning groove 205, the position of the fixing rod 208 can be restricted.

The outer wall of the ventilation filter 6 is fixedly connected to the inside of the protective shell 7. The gear 204 meshes with the rack 206. The fixing rod 208 engages with the positioning groove 205. By inserting the fixing rod 208 into the positioning groove 205, the position of the fixing rod 208 can be restricted.

[0040] Working principle: The operator simultaneously pulls the fixed short rod 208 to both sides, compressing the spring 209 to retract, causing the fixed short rod 208 to disengage from the positioning groove 205 on the outer wall of the rotating short column 203, releasing the lock on the gear 204, and pulling the protective shell 7 axially backward, causing the elongated plate 201 and rack 206 to move synchronously. The rack 206 meshes with the gear 204, driving the gear 204 to rotate clockwise until the rack 206 is completely disengaged from the hollow block 202, completing the disassembly of the protective shell 7. When installation is required, align the rack 206 on the rear side of the protective shell 7 with the opening of the hollow block 202, and push the protective shell 7 forward. 6 re-engages with gear 204, driving gear 204 to rotate counterclockwise. Rack 206 gradually penetrates into hollow block 202. When rack 206 is fully inserted, the positioning groove 205 on rotating short column 203 realigns with the position of fixed short rod 208. Spring 209 releases elastic potential energy, pushing fixed short rod 208 to reset, causing its end to re-engage with positioning groove 205, locking the position of gear 204 and preventing rack 206 from coming out. This achieves the effect that when the internal components of the electronic switch malfunction, maintenance personnel can quickly replace the module without disassembling the entire steering wheel, by directly separating the protective shell 7 through quick-release mechanism 2.

[0041] The motor 3031 is powered by the drive battery 3034, which then starts the output shaft of the motor 3031 to drive the worm gear 3033 to rotate. The worm gear 3032 meshes with the worm wheel 3032 at the bottom of each rotating column 302. The worm wheel 3032 drives the fan blade 301 to rotate through the rotating column 302, and pushes the air out of the protective shell 7 during rotation, forming a forced convection cooling cycle, which avoids the problem of damage to the modular steering wheel electronic switch due to high temperature.
