Detailed Description

The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.

As shown in fig. 1, the present embodiment provides a massage chair control key, including: the circuit board 1 is provided with a plurality of switch parts which can be switched on and off; the conducting strip covers the circuit board 1, the surface of the conducting strip facing the circuit board 1 is provided with a plurality of conducting contacts, and the conducting contacts are in one-to-one correspondence with the switch parts and are in contact with the switch parts; the pressing assembly comprises a key and a key frame 3, the key frame 3 is provided with a plurality of key holes 31, the key is provided with a plurality of movable blocks 4, the key is arranged on the key frame 3, each movable block 4 is positioned in one key hole 31, and the movable blocks 4 are in sliding fit with the inner wall of the key holes 31; the key frame 3 is fixed on the circuit board 1, and each key hole 31 is opposite to one conductive contact.

The utility model adopts the matching of the key frame 3 and the keys, and utilizes each movable block 4 on the keys to be arranged in the corresponding key hole 31, and utilizes the hole wall to realize the motion guidance of the movable block 4; when a certain position of the key is pressed by a hand, the movable block corresponding to the position moves downwards along the axial direction of the key hole 31, so that the touch and press work of the conducting strip is realized, and the problems of key clamping, stiff hand feeling, easy damage and the like of a common key switch can be effectively solved.

As shown in fig. 1, the movable block 4 is detachably connected to the cover 2 on the key, the cover 2 is provided with a locking hole 21, specifically, the movable block 4 is provided with a locking hook 42, the locking hook 42 is disposed in the locking hole 21, the cover 2 and the movable block 4 are combined into a key through a buckle structure, the key is disposed in the key hole 31 of the key frame 3, the key frame 3 is provided with a plurality of key holes 31, as shown in fig. 2, the inner sides of the key holes 31 of the key frame 3 are large guide surfaces 301, in this embodiment, the protrusion surfaces are disposed on the peripheral hole walls of the key holes 31 to serve as the large guide surfaces 301, the key formed by the cover 2 and the movable block 4 can reciprocate vertically to the end surface of the key frame 3 under the guiding effect of the large guide surfaces 301 inside the key holes 31 of the key frame 3, the large guide surfaces 301 are more favorable for the axial movement, and avoid the problem of locking.

The fitting of the key hole 31 to the movable block 4 is not limited to this, and it may be fitted to each other by a structure such as a guide rib and a groove. The positioning salient point 41 of the movable block 4 is matched with the positioning groove on the inner side of the key hole 31 of the key frame 3 to realize the positioning function, so that the movable block 4 can not pass through the key hole 31 in the key frame 3 when moving in the key frame 3, and the positioning groove has a space for the positioning salient point 41 to axially move, so that the key formed by combining the cover part 2 and the movable block 4 can be ensured to axially reciprocate along the large guide surface 301 on the inner side of the key hole 31 of the key frame 3.
