Summary of the Utility Model

[0003] The purpose of the utility model is to provide a rolling and pressing vehicle switch to solve the problems of unclear rotational gear feeling and large occupied layout area of the existing switch structure.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a rolling and pressing vehicle switch, including a housing, an inner housing that can move up and down arranged in the housing, a base assembled at one end of the housing, and a circuit board placed in the base; a roller is arranged on the inner housing, a rotating disc that drives the roller to rotate is sleeved inside the roller, a rotating support shaft is arranged at one end of the rotating disc, the rotating support shaft rotates and supports on the inner housing, a track body that rotates together with the rotating disc is clamped at the other end of the rotating disc, a gear track for realizing the gear feel is arranged on the inner circle of the track body, a gear lever is further arranged in the track body, one end of the gear lever is fixed on the inner housing, and the other end rotates and supports on the rotating disc; a gear bead that cooperates with the gear track is arranged on the gear lever, and a top spring is arranged between the gear bead and the gear lever.

[0005] To achieve the conduction of the rotation gear signal, a photoelectric sensor is provided on the circuit board.

A transmission gear is provided between the driving gear and the driven gear.

[0006] To achieve the conduction of the pressing signal, a conductive rubber is further provided on the circuit board, and a conductive rubber button that cooperates with the inner shell is provided on the conductive rubber.

[0007] To achieve the cooperation between the gear lever and the rotating disc so that the rotating disc can rotate while the gear lever does not rotate, a gear lever rotating mounting shaft is provided at one end of the gear lever that cooperates with the rotating disc, and a mounting hole that cooperates with the gear lever rotating mounting shaft is provided on the rotating disc.

[0008] To achieve the synchronous rotation of the track body with the rotating disc, a set of clamping pieces is provided on the end face of the rotating disc that cooperates with the track body, and a clamping groove that cooperates with the clamping pieces is provided on the end face of the track body.

[0009] A set of limiting ribs arranged along the axis of the roller is provided on the inner wall of the roller, and a limiting boss is also provided. A set of limiting grooves that cooperate with the limiting ribs is provided on the rotating disc, and a buckle that cooperates with the limiting boss for clamping is also provided.

[0010] To ensure the vertical movement of the inner shell and prevent the inner shell from shaking when moving downward, a set of vertical guiding grooves is provided on the outer side wall of the inner shell, and the vertical guiding grooves extend from the upper end face of the inner shell to the lower end face of the inner shell.

[0011] The beneficial effects of the present utility model: Through the cooperative design of the roller with the rotating disc, the track body and the gear lever, the present utility model has a compact structure and occupies a small space. The gear feel is realized by the cooperation of the gear beads and the gear tracks in the track body. Under the action of the ejecting spring, the gear beads always press on the gear tracks with a certain pressure, so the gear is clearer, and when the roller rotates, the gear feel is better. The gear transmission is adopted between the rotating disc and the light-shielding sheet, which not only has good reliability but also has a small thickness. Therefore, this switch is small in size in terms of length and width, and can reduce the layout area occupied by the switch in the vehicle. At the same time, this switch is tall, so longer vertical guiding grooves can be arranged on the inner shell. Cooperating with the vertical guiding ribs, the shaking amount is smaller after being subjected to force extrusion, and the structural reliability is high.

[0018] Example, as Figures 1 to 5 shown, a rolling press automotive switch includes a housing 1, and an inner housing 2 disposed inside the housing 1 and capable of moving up and down. To ensure the stability of the operation of the inner housing 2 and improve reliability, a set of vertical guiding grooves 21 are provided on the outer sidewall of the inner housing 2, and the vertical guiding grooves 21 extend from the upper end surface of the inner housing 2 to the lower end surface of the inner housing 2. A set of vertical guiding ribs 101 are provided on the inner wall of the housing 1 that mates with the inner housing 2.

[0019] One end of the housing 1 is snap-fitted with a base 3, a circuit board 4 is disposed inside the base 3, a photoelectric sensor 11 is provided on the circuit board 4, and a light-shielding sheet 12 that mates with the photoelectric sensor 11 is rotatably mounted on the inner housing 2. The on-off of the signal of the photoelectric sensor 11 is controlled by the rotation of the light-shielding sheet 12. The light-shielding sheet 12 is fixedly disposed on a light-shielding sheet rotating shaft 13, and the light-shielding sheet rotating shaft 13 is rotatably mounted on the inner housing 2. A conductive rubber 16 is further provided on the circuit board 4, and a conductive rubber button 161 is provided on the conductive rubber 16. When the inner housing 2 moves downward to press the conductive rubber button 161, the conductive rubber button 161 is deformed to contact and conduct with the circuit board 4.

[0020] To realize the rotation of the light-shielding sheet 12 and the up-and-down movement of the inner housing 2, a roller 5 that can rotate and drive the inner housing 2 to move downward together when pressed is provided on the inner housing 2. The connection structure between the roller 5 and the inner housing 2 is specifically as follows:

[0021] A rotating disk 6 that drives the roller 5 to rotate is sleeved inside the roller 5. To facilitate installation and enable the roller 5 to drive the rotating disk 6 to rotate together, a set of limiting ribs 51 arranged along the axis of the roller 5 are provided on the inner wall of the roller 5, and a limiting boss 52 is further provided. A set of limiting grooves 65 that mate with the limiting ribs 51 are provided on the rotating disk 6, and a snap 66 that mates with the limiting boss 52 is further provided. After the rotating disk 6 is installed in the roller 5, the snap 66 is snap-fitted on the limiting boss 52, and the limiting ribs 51 are located in the limiting grooves 65.

[0022] One end of the rotating disc 6 is provided with a rotating support shaft 61, and the rotating support shaft 61 is rotatably supported on the inner shell 2. The inner shell 2 is provided with a support arm 22 that cooperates with the rotating support shaft 61, and the support arm 22 is provided with a mounting hole that cooperates with the rotating support shaft 61. To drive the light-shielding sheet 12 to rotate, a driving gear 62 is fixedly provided on the rotating support shaft 61. One end of the light-shielding sheet rotating shaft 13 is provided with a driven gear 14, and a transmission gear 15 is provided between the driving gear 62 and the driven gear 14. The transmission gear 15 is rotatably mounted on the inner shell 2 through a rotating shaft. The rotating roller 5 drives the rotating disc 6 to rotate, and the rotating disc 6 drives the driving gear 62 to rotate. Under the action of gear meshing, the light-shielding sheet 12 is driven to rotate.

[0023] To achieve the rotation feel, a track body 7 that rotates together with the rotating disc 6 is clamped at the other end of the rotating disc 6. Specifically, a set of clamping pieces 64 are provided on the end surface of the rotating disc 6 that cooperates with the track body 7, and a clamping groove 72 that cooperates with the clamping pieces 64 is provided on the end surface of the track body 7. The clamping groove 72 can be inserted into the clamping pieces 64, so that when the rotating disc 6 rotates, the track body 7 rotates together. A gear position track 71 for realizing the gear position feel is provided on the inner ring of the track body 7, and the gear position track 71 is a set of concave and convex surfaces arranged along the inner ring of the track body 7. To cooperate with the gear position track 71 to achieve the gear position feel, a gear position rod 8 is inserted into the inner ring of the track body 7. The gear position rod 8 is a fixed part and does not rotate together with the track body 7. A gear position bead 9 that cooperates with the gear position track 71 is provided on the gear position rod 8, and a top spring 10 is provided between the gear position bead 9 and the gear position rod 8. A spring mounting hole is provided on the gear position rod 8. After the top spring 10 is installed in the spring mounting hole, the gear position bead 9 is placed on the top spring 10, and then the gear position rod 8 is installed in the track body 7. Under the action of the top spring 10, the gear position bead 9 presses on the gear position track 71. The track body 7 rotates, so that different positions of the gear position track 71 contact the gear position bead 9, thereby generating a gear position rod.

[0024] One end of the gear position rod 8 is fixed on the inner shell 2, and the other end is rotatably supported on the rotating disc 6. Specifically, a gear position rod rotating mounting shaft 81 is provided at the end of the gear position rod 8 that cooperates with the rotating disc 6, and a mounting hole 63 that cooperates with the gear position rod rotating mounting shaft 81 is provided on the rotating disc 6. This cooperation structure makes it so that when the rotating disc 6 rotates, the gear position rod 8 does not rotate together with the rotating disc 6, thereby keeping the gear position rod 8 stationary.

Obviously, the specific implementation of the present utility model is not limited by the above-mentioned manner. As long as various non-substantive improvements are made by adopting the method concept and technical solution of the present utility model; or without improvement, the above-mentioned concept and technical solution of the present utility model are directly applied to other occasions, they are all within the protection scope of the present utility model.
