[0031] The elastic bracket 8 includes a hollow block 81, the upper surface of the hollow block 81 is fixedly connected to the bottom of the shell 1, the inner wall of the hollow block 81 is fixedly connected to a first spring 82, and the left and right sides of the first spring 82 are fixedly connected to a cross plate 83, the elastic force of the first spring 82 is greater than the gravity of the cross plate 83, and a guide hole 84 is opened inside the cross plate 83. The inner wall of the guide hole 84 contacts the surface of the locking bracket 9, and a hollow cylinder 85 is fitted on the surface of the cross plate 83. The upper surface of the hollow cylinder 85 is fixedly connected to the bottom of the shell 1, and the cross plate 83 can only move left and right through the hollow cylinder 85.

[0032] The locking bracket 9 includes a second U-shaped plate 91, and the front and rear sides of the shell 1 are in contact with the inner wall of the second U-shaped plate 91. The front and rear sides of the inner wall of the second U-shaped plate 91 are fixedly connected with a cylinder 92, and the surface of the cylinder 92 is in contact with the inner wall of the guide hole 84. The front and rear sides of the inner wall of the second U-shaped plate 91 are fixedly connected with a locking column 93. The inner wall of the first strip hole 7 and the inner wall of the first U-shaped plate 6 are in contact with the surface of the locking column 93. Through the cooperation of the first strip hole 7 and the locking column 93, the second U-shaped plate 91 can only move up and down. When the locking column 93 is inserted into the first U-shaped plate 6, the locking column 93 can cooperate with the first U-shaped plate 6. The lighting module 3 and the wiper module 5 are respectively fixed on the shell 1. When the locking column 93 is separated from the first U-shaped plate 6, the lighting module 3 and the wiper module 5 can be directly separated from the shell 1. The guide hole 84 is composed of a section of inclined hole and a section of horizontal hole. When the cylinder 92 moves in the inclined hole, the locking column 93 moves upward or downward through the cooperation of the guide hole 84 and the cylinder 92. When the cylinder 92 is located in the horizontal hole, the locking column 93 and the first U-shaped plate 6 cannot be separated through the cooperation of the guide hole 84 and the cylinder 92. At the same time, the elastic force of the first spring 82 makes it impossible for the cylinder 92 and the horizontal hole on the guide hole 84 to be automatically separated.

[0033] Embodiment 2:

[0034] Reference Figure 4-11 The inner wall of the first mounting groove 2, the front and rear sides of the light module 3, the inner wall of the second mounting groove 4, the front and rear sides of the wiper module 5 and the side of the first U-shaped plate 6 are all fitted with a column 10, and the side of the column 10, the inner wall of the first mounting groove 2 and the inner wall of the second mounting groove 4 are all fixedly connected with a second spring 11, and the upper and lower sides of the column 10 are provided with a slide groove 12, and the upper and lower sides of the inner wall of the first mounting groove 2 and the upper and lower sides of the inner wall of the second mounting groove 4 are fixedly connected with a guide column 13, and the surface of the guide column 13 is connected to the inner wall of the first mounting groove 2. The inner wall of the slide groove 12 is in contact with the guide column 13, and the column 10 can only move left and right through the cooperation of the guide column 13 and the slide groove 12. When the light module 3 and the wiper module 5 are fixed in the shell 1, the second spring 11 can be compressed through the first U-shaped plate 6. Then, when the locking column 93 is separated from the first U-shaped plate 6, the thrust of the second spring 11 on the column 10 assists the user to remove the light module 3 and the wiper module 5 from the shell 1, thereby facilitating the user to remove the light module 3 and the wiper module 5 from the shell 1.

[0035] Embodiment three:

The sealing ring 14 can seal the gap between the lighting module 3 and the first mounting groove 2 or the gap between the wiper module 5 and the second mounting groove 4.

[0037] In the present invention, when the user inspects the steering wheel combination switch, the user first pushes the horizontal plate 83 to move the cylinder 92 into the inclined hole on the guide hole 84, and then, through the cooperation of the inclined hole and the cylinder 92, the locking column 93 moves downward. When the locking column 93 is separated from the first U-shaped plate 6, the thrust of the second spring 11 on the column 10 can stagger the first U-shaped plate 6 and the locking column 93, so that the light module 3 and the wiper module 5 can be taken out of the housing 1. When it is necessary to fix the light module 3 and the wiper module 5 on the housing 1, the user first pushes the horizontal plate 83 to move the cylinder 92 into the inclined hole on the guide hole 84, and then, through the cooperation of the inclined hole and the cylinder 92, the locking column 93 is moved to At the lowest point, then, insert the light module 3 into the first mounting groove 2 or insert the wiper module 5 into the second mounting groove 4. When the first U-shaped plate 6 is aligned with the locking column 93, release the horizontal plate 83, and use the first spring 82 to push the horizontal plate 83 to move the cylinder 92 from the inclined hole on the guide hole 84 to the horizontal hole. At this time, through the cooperation of the inclined hole and the cylinder 92, the locking column 93 is inserted into the first U-shaped plate 6, and through the cooperation of the horizontal hole and the cylinder 92, the locking column 93 is fixed in the first U-shaped plate 6. At this time, through the cooperation of the locking column 93 and the first U-shaped plate 6, the light module 3 can be fixed in the first mounting groove 2, or the wiper module 5 can be fixed in the second mounting groove 4.
