Description

Technical Field

[0001] This utility model relates to the field of steering wheel technology, specifically to a car steering wheel switch connection structure. Background Technology

[0002] The steering wheel is a wheel-shaped device for controlling the direction of a car. Its function is to convert the force applied by the driver to the edge of the steering wheel into torque and transmit it to the steering shaft.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figure 1-4 As shown, in this embodiment, a car steering wheel switch connection structure includes a steering wheel body 1. A mounting groove 2 is formed on the outer surface of the steering wheel body 1. A switch 3 is disposed inside the mounting groove 2. A docking groove 4 is formed at the bottom of the switch 3. Multiple slots 5 are formed inside the docking groove 4. A docking seat 7 is fixedly connected to the bottom surface of the mounting groove 2 at its center. Multiple receiving holes 11 are formed through the outer surface of the docking seat 7. Each of the multiple receiving holes 11 has a slidably connected locking head 12. An adjusting screw 8 is rotatably connected inside the docking seat 7. A driven plate is threadedly connected to the outer surface of the adjusting screw 8. 9. Multiple connecting rods 10 are rotatably connected to the top of the driven plate 9. The other end of the multiple connecting rods 10 is rotatably connected to the bottom end of multiple clips 12. One end of the multiple clips 12 is inserted into the interior of multiple slots 5. The clips 12 can be stored and limited by the storage through hole 11. The driven plate 9 can drive the connecting rods 10 to move during the movement. The connecting rods 10 can push the clips 12 to move during the movement of the driven plate 9. The slots 5 can fix the switch 3 inside the mounting slot 2 by cooperating with the clips 12.

[0022] like Figure 2 and Figure 5 As shown, the bottom end of the adjusting screw 8 is fixedly connected to a polygonal connecting column 14 through the bottom surface of the docking seat 7. A movable sleeve 15 is slidably connected to the outside of the polygonal connecting column 14. A fixed seat 16 is inserted into the top of the movable sleeve 15. The top of the fixed seat 16 is fixedly connected to the outer surface of the steering wheel body 1. By setting the movable sleeve 15, the adjusting screw 8 can be rotated by cooperating with the polygonal connecting column 14 for easy adjustment, and the adjusting screw 8 can be fixed by cooperating with the fixed seat 16.

[0023] like Figure 5As shown, a limiting plate 17 is fixedly connected to the bottom of the polygonal connecting column 14, and the top of the movable sleeve 15 is interference-fitted with the inside of the fixed seat 16. By setting the limiting plate 17, the movable sleeve 15 can be limited to prevent it from falling off. By setting the top of the movable sleeve 15 to the inside of the fixed seat 16, the tightness of the connection between the two can be improved.

[0024] like Figure 3 and Figure 4 As shown, a positioning block 13 is fixedly connected to the outer surface of the docking seat 7, and a positioning groove 6 is provided on the inner surface of the docking groove 4. The outer surface of the positioning groove 6 is slidably inserted into the inner surface of the positioning block 13. By setting the positioning block 13 and the positioning groove 6, relative rotation between the two can be prevented, and the switch 3 can be prevented from shaking.

[0025] like Figure 2 and Figure 4 As shown, four movable seats 18 are fixedly connected to the bottom surface inside the mounting slot 2. Each of the four movable seats 18 is slidably connected to a push rod 19. Each of the four movable seats 18 is fixedly connected to a pressure spring 20. The top ends of the four pressure springs 20 are fixedly connected to the bottom ends of the four push rods 19 respectively. By setting the pressure springs 20, a continuous force can be applied to the push rods 19, so that the switch 3 can be pushed out of the mounting slot 2 after disassembly, making it convenient to take out the switch 3.

[0026] like Figure 4 As shown, two limiting grooves 21 are provided on the inner surface of the docking seat 7, and two limiting blocks 22 are provided on the outer surface of the driven plate 9. The outer surfaces of the two limiting blocks 22 are slidably connected to the inner surfaces of the two limiting grooves 21, which can limit the driven plate 9 and prevent it from rotating during the adjustment of the adjusting screw 8.

[0027] This utility model provides a car steering wheel switch connection structure, the specific working principle of which is as follows:

[0028] When the switch 3 needs to be disassembled and repaired, the staff pulls out the movable sleeve 15. After the movable sleeve 15 is pulled out, rotating the movable sleeve 15 drives the adjusting screw 8 to rotate, causing the driven plate 9 to move downward under the action of the adjusting screw 8. The movement of the driven plate 9 drives the connecting rod 10 to move and pulls the clamp 12 to slide in the receiving through hole 11, so that the clamp 12 disengages from the clamp slot 5 and releases the restriction between the docking slot 4 and the docking seat 7. Then, the pressure spring 20 restores its elastic deformation and pushes the push rod 19 to move upward in the movable seat 18, pushing the switch 3 out of the mounting slot 2. The staff then takes out the switch 3 for repair.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
