Detailed Implementation

[0022] 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.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] In this technical solution, a tactile switch with a five-way roller includes a switch base 12. A lower roller cover 11 is mounted on the top of the switch base 12, and an upper roller cover 11 is mounted on the top of the lower roller cover 11. A transmission spring seat 5 is mounted inside the lower roller cover 11, and a spring 8 is mounted inside the transmission spring seat 5. Ball bearing seats 6 are mounted at both ends of the transmission spring seat 5 inside the lower roller cover 11, and balls 7 are installed inside the ball bearing seats 6. A roller intermediate transmission ring 3 is mounted on the inner side of the upper roller cover 1, and roller transmission teeth 4 are mounted on the outer wall of the roller intermediate transmission ring 3. A roller 2 is mounted inside the roller intermediate transmission ring 3. A roller cavity is opened at the top of the upper roller cover 1, and the roller 2 is disposed within the roller cavity. An optocoupler element 13 is mounted on the top of the switch base 12, and a guide post 14 is mounted on the top of the switch base 12. A ball bearing upper cover 9 is mounted on the side wall of the balls 7, and an optocoupler positioning shaft 10 is mounted inside the ball bearing upper cover 9.

[0025] In this technical solution, the upper cover 1 of the roller moves left and right, causing the lower cover 11 of the roller to move downward to the guide post to achieve the downward pressing. The rolling is transmitted from the isolated roller to the middle transmission ring, and then from the spring 8 to the upper cover 9 of the ball bearing to achieve the rolling. The transmission spring seat 5, the ball bearing seat 6, the ball 7, the spring 8 and the upper cover 9 cooperate to achieve the feel. The upper cover 1 of the roller presses down to the lower cover 11 of the roller, and then to the guide post 14 to achieve the downward pressing. The main adjustment is the elastic structure at point b, which uses steel balls to cooperate with the ball groove. The transmission spring seat 5, the roller 2 and the middle transmission ring 3 of the roller are regarded as a shaft. The ball 7 is stable under the action of the spring, and strikes the groove of the ball bearing seat with a hemispherical ball to achieve the feel. The ball bearing seat 6 and the lower cover 11 of the roller are positioned and assembled as a whole to enhance the rolling stability.

[0026] In some technical solutions, the ball bearing seat 6 includes a bearing a61 and a bearing b62 arranged opposite to each other. The inner walls of the bearing a61 and the bearing b62 are evenly spaced along their axis with steel ball mating grooves 15. Steel balls 22 are assembled inside the steel ball mating grooves 15. The inner wall of the ball bearing seat 6 is provided with a transmission spring seat groove 23. The outer wall of the ball bearing seat 6 is provided with a steel ball mating feel boss 21. The ball 7, through the cooperation of the steel ball mating groove, the steel ball mating feel boss and the transmission spring seat groove 23, achieves a smooth and strong feel (hemispherical). The transmission spring seat groove 23 achieves stable coverage of the spring circumference, making the spring less prone to shaking and deformation.

[0027] In this technical solution, the ball bearing seat 6 is composed of a combination of a bearing seat a61 and a bearing seat b62 arranged opposite to each other, and the ball 21 can roll in the rotating cavity 22, thereby improving the transmission efficiency of the ball bearing seat 6.

[0028] In some technical solutions, connecting plates 18 are installed on both outer walls of bearing a61 and bearing b62. The side walls of the connecting plates 18 are provided with screw holes 17, and bolts 19 are installed inside the screw holes 17.

[0029] In this technical solution, bearing a61 and bearing b62 are combined and fixed by a threaded connection.

[0030] In some technical solutions, oil injection holes 16 are installed on the outer walls of both bearing a61 and bearing b62.

[0031] In this technical solution, the oil injection hole 16 and the rotating cavity 22 are connected, and lubricating oil can be added into the cavity.

[0032] In some technical solutions, a plug 20 is inserted into the inside of the oil filling hole 16.

[0033] In this technical solution, the oil injection hole can be sealed.

[0034] Working principle:

[0035] When in use, the upper cover 1 of the roller moves left and right, causing the lower cover 11 of the roller to move downward to the guide post to achieve the downward pressing. The rolling is transmitted from the isolated transmission ring of the roller to the middle transmission ring, and then from the spring 8 to the upper cover 9 of the ball to achieve the rolling. The transmission spring seat 5, the ball seat 6, the ball 7, the spring 8 and the upper cover 9 cooperate to achieve the feel. The upper cover 1 of the roller presses down to the lower cover 11 of the roller, and then to the guide post 14 to achieve the downward pressing. The main adjustment is the elastic structure at point b, which is made of steel ball and ball groove.
