Description

Technical Field

[0001] The utility model relates to a hand-held switch with a motion conversion mechanism, belonging to the field of doors and windows. Background Art

[0002] There are backlight and working indication requirements on the side of the switch, which are perpendicular to the direction of button pressing. Generally, two perpendicular circuit boards are designed: one is used for the placement of backlight and working indicator LED (or micro switch with bent feet or contact movement), and the other is used for conductive rubber or micro switch.

[0003] For the condition of high durability of ≥ 200,000 times, large stroke, large operating force and low sound, micro switches and contacts cannot meet the requirements; while the use of conductive rubber affects the space layout and cost, and is limited by the durability of the switch. Therefore, a conversion mechanism that does not affect the space and reduces the cost is needed. Utility Model Content

[0023] like Figure 1-4 As shown, an embodiment of the hand-held switch with a motion conversion mechanism of the utility model includes a shell 1, in which a button 2, a lever 3, a conductive rubber 4 and a circuit board 5 are arranged. The button 2 includes a horizontally arranged pushing portion 21, and the lever 3 is vertically movably installed in the shell 1. The pushing portion 21 is linked with the lever 3. The button 2 drives the pushing portion 21 to horizontally push the lever 3 downward to press the conductive rubber 4 through a pressing action, so that the conductive rubber 4 and the circuit board 5 form a circuit path. By improving the structure of the switch, the button 2 cooperates with the lever 3 to press the conductive rubber 4 to trigger the circuit board 5 to conduct electricity. The horizontal movement of the button 2 pushes the lever 3 to vertically move to press the conductive rubber 4, and the two perpendicular circuit boards 5 are optimized into one circuit board 5, integrating the two functions of backlight and working indicator light, reducing costs and space requirements, and improving the use effect and service life of the switch.

[0024] The lever 3 includes a pressing portion 31 and a pushing groove 32 provided on one side of the pressing portion 31. The pushing portion 21 is arranged in an annular shape and is snap-connected with the pushing groove 32 on the side away from the button 2. After the button 2 is pressed, the pushing portion 21 drives the lever 3 to move in the vertical direction to trigger the conductive rubber 4. The button 2 moves and drives the lever 3 to move through the snap-connection between the pushing groove 32 and the pushing portion 21. The snap-connection between the pushing groove 32 and the pushing portion 21 is reliable and stable. The annular arrangement can prevent the pushing portion 21 from falling out, thereby preventing the problem of structural failure.

[0025] A limiting arm 33 extends from one end of the pushing groove 32 away from the button 2, and the pushing portion 21 abuts against the inner wall of the limiting arm 33. The limiting arm 33 is arranged on the pushing groove 32 so that the pushing portion 21 of the button 2 can stably drive the lever 3 to move and press the conductive rubber 4, and the pushing groove 32 limits the pushing portion 21, so that the button 2 can drive the lever 3 to move.

[0026] The pressing portion 31 is provided with a pressing groove 35, and the end of the conductive rubber 4 extends into the pressing groove 35 and is connected with the pressing groove. The pressing groove 35 cooperates with the conductive rubber 4, so that the lever 3 can stably press the conductive rubber 4 when moving vertically to trigger the circuit board 5, and the lever 3 has a small stroke for pressing the conductive rubber 4 and a stable triggering effect, which can improve the durability and use effect of the conductive rubber 4.

[0027] The pressing portion 31 and the conductive rubber 4 are located inside the pushing portion 21 to form a stacked mounting structure therewith. The pressing portion 31, the conductive rubber 4 and the pushing portion 21 are arranged into a stacked mounting structure, which greatly saves the installation space inside the switch and reduces the cost.

[0028] A positioning groove 11 is provided on the inner wall of the housing 1, and a positioning portion 34 is provided on the lever 3 to be engaged with the positioning groove 11 at the initial position. The positioning portion 34 can enable the lever 3 to move in the vertical direction and limit the position of the lever 3 from moving in the initial state. After resetting, the position of the lever 3 can also be fixed to facilitate the next pressing of the button 2.

[0029] The positioning portion 34 is cylindrical and longitudinally installed in the positioning groove 11. The cylindrical shape of the positioning portion 34 enables the lever 3 to smoothly move out of the positioning groove 11 when being driven to move, thereby preventing the lever 3 from getting stuck and improving the use effect.

[0030] The housing 1 is provided with a sliding groove 12, and the button 2 is provided with a sliding portion 22 slidably connected to the sliding groove 12. The sliding groove 12 and the sliding portion 22 cooperate to limit the travel of the button 2, which will not be pressed excessively and has a more stable structure.
