Technical Field

[0001] The utility model relates to the field of controllers for massage chairs, in particular to a key device of a controller. Background Art

[0002] At present, most controllers used in massage chairs are in the form of push buttons, which are relatively traditional. For the seesaw-type toggle switch, which is more popular in automobile switches, such as headlight adjustment switches, audio volume adjustment switches, air conditioning air volume adjustment switches, etc., all use it. This toggle switch transmits the force to electronic components such as micro switches through mechanical parts to realize the function. This assembly method generally requires the cooperation of multiple transmission parts to complete. For example, in addition to the key circuit, it also includes a seesaw spring, a rotating toggle member, a lever assembly, etc. The lever assembly includes a lever and a spring member, etc. The lever assembly is arranged on one side of the rotating toggle member and rests on the seesaw spring, and rotates when the rotating toggle member rotates; the rotating toggle mechanism drives the seesaw spring to rotate by rotating, so that the seesaw spring squeezes the elastic protrusion of the silicone member, so that the conductive layer contacts the contact electrode on the circuit board. If this switch structure is to be applied to the massage chair controller, a large space needs to be reserved for structural design. Utility Model Content

When the keys 31 are pressed in place, they can contact the corresponding contacts. At the same time, the sensors 22 can sense that the keys 31 are pressed in place, and the circuit board 20 issues a corresponding control command. The keys 31 can return to their original positions after being released.

[0034] The toggle member 40 is rotatably connected to the housing 10. An installation opening 11 is provided on the housing 10, and the installation opening 11 penetrates into the housing 10. Two opposite side walls of the installation opening 11 are respectively provided with installation grooves 12.

The two side walls of the installation opening 11 with the installation grooves 12 are set as the first side walls, and the other two opposite side walls except the second side wall are set as the second side walls. The connecting line of the two protrusions 42 of the toggle member 40 is used as the rotating axis of the toggle member 40. Then the toggle member 40 can be toggled to rotate around the rotating axis between the two second side walls.

[0035] A plurality of driving parts 41 are provided on the side of the toggle member 40 relative to the flexible key plate 30, that is, the driving part 41 is located in the housing 10, and the driving part 41 extends outward along the side wall of the toggle member 40, and the driving part 41 can be located on the side wall of the toggle member 40 opposite to the second side wall of the installation opening 11. A toggle part 44 is provided on the side of the toggle member 40 away from the flexible key plate 30. The size of the toggle member 40 gradually decreases from the side relative to the flexible key plate 30 to the toggle part 44. Specifically, the size of the toggle member 40 relative to the flexible key plate 30 is greater than or equal to the size of the installation opening 11, and the size of the toggle member 40 away from the flexible key plate 30 is less than the size of the installation opening 11.

When the toggle part 44 is toggled in the direction of one of the second side walls, the driving part 41 close to the second side wall pushes the corresponding slider 51, and the slider 51 presses the corresponding button 31 in place, the contact point corresponding to the button 31 is triggered, and the sensor senses that the button 31 is pressed in place; the other driving part 41 is tilted away from the corresponding slider 51, the slider 51 does not move, and the sensor 22 corresponding to the button 31 is not triggered. Similarly, when the toggle portion 44 is pushed toward the direction of the other second side wall, the driving portion 41 pushes the corresponding slider 51, and the slider 51 presses the corresponding button 31 into place, the contact point corresponding to the button 31 is triggered, and the sensor senses that the button 31 is pressed into place.

[0039] In order to limit the slider 51, a plurality of limit grooves 13 are further provided in the housing 10. The plurality of limit grooves 13 are located at the outer periphery of the toggle member 40, that is, located outside the side wall of the mounting opening 11 having the driving portion 41.

The number of the first guide portions 14 can be multiple, respectively located on different side walls of the limiting groove 13, and the number of the second guide portions 52 corresponds to the number of the first guide portions 14, respectively located on different side walls of the slider 51. Among them, the first guide portion 14 and the corresponding second guide portion 52 can be concave-convex matched, for example, the first guide portion 14 is a convex strip, the second guide portion 52 is a concave groove, or the first guide portion 14 is a concave groove, and the second guide portion 52 is a convex strip.

[0041] Since there is a gap between the toggle member 40 and the mounting opening 11 of the housing 10, a decorative member 60 can be provided, and the decorative member 60 is fixed to the housing 10 where the toggle member 40 is located, so that the housing 10 has a more beautiful appearance. The decorative member 60 is also provided with a clearance hole 61 for the toggle member 40 to pass through, and the size of the clearance hole 61 is reasonably set so as not to affect the movement of the toggle portion 44.
