[0029] Please refer to Figure 1A , which is shown as a schematic diagram of the disassembled structure of the base and button of a switch in an implementation manner of the present application. As Figure 1AAs shown in the figure, the switch 1 includes a base 10 and at least one button 20. Among them, the base 10 is a structure connected to the installation base surface, realizing a stable connection between the switch 1 and the installation base surface. The button 20 is pivotally arranged on the base 10, capable of pivoting, and the opening and closing of the switch 1 are realized through pivoting. Those skilled in the art can understand that, for example, the switch can be a single-button switch, a double-button switch, or a control switch with three or more buttons, but the adjustments and variations of these related solutions are within the protection scope of this application.

[0030] As Figure 1A shown in the figure, the base 10 is provided with a receiving groove 101, and a variety of structural members are arranged in the receiving groove 101 to realize the connection between the base 10 and the installation base surface.

[0031] Continuing to refer to Figure 1A , a pressing plate 30 and a swinging member 40 are assembled in the receiving groove 101. The swinging member 40 is pivotally arranged on the pressing plate 30 with its first central axis L1 as the pivot.

[0032] On the surface of the swinging member 40 facing away from the pressing plate 30, a pair of first engaging grooves 401 and a pair of second engaging grooves 402 are provided. The first engaging grooves 401 are symmetrically arranged with the second central axis L2 of the swinging member 40 as the symmetry axis, and the second engaging grooves 402 are symmetrically arranged with the first central axis L1 of the swinging member 40 as the symmetry axis. The first central axis L1 is perpendicular to the second central axis L2.

[0033] The button 20 is pivotally arranged on the pressing plate 30 with its axis parallel to the first central axis L1 as the pivot. As Figure 1B shown in the figure, the button 20 is provided with 4 button buckles 201 on the surface facing the swinging member 40. Among them, two button buckles 201 are in one-to-one cooperation with the first engaging grooves 401, and the other two button buckles 201 are in one-to-one cooperation with the second engaging grooves 402, thus solving the problem of button shaking and achieving the effect of button fixation and balance when pressing the button. In this embodiment, one button 20 corresponds to and cooperates with one swinging member 40. The swinging member 40 is clamped to the inner wall of the button through the button buckles and the first engaging grooves 401 and the second engaging grooves 402, and the swinging member 40 is driven to move by applying pressing actions in different directions to the button.

[0034] In order to better realize the pivoting effect and stability of the swinging member and the button, as Figure 2 shown in the figure, a pair of rotating shaft brackets 301 are symmetrically arranged on the pressing plate 30. The rotating shaft brackets 301 are symmetrically arranged with the central axis of the pressing plate 30 as the symmetry axis, and the central axis of the pressing plate 30 is parallel to the second central axis L2. A shaft hole and a button rotating shaft 301A are arranged on the rotating shaft bracket 301. The button rotating shaft 301A is located on the side of the rotating shaft bracket 301 facing away from the swinging member 40.

[0035] To better adapt to the pressing plate, as Figure 3 shown, the swinging member 40 is provided with avoiding grooves 403 on the first side surface and the second side surface facing the rotating shaft bracket 301. A swinging rotating shaft 403A corresponding to the shaft hole is arranged in the avoiding groove 403, and the shape and contour of the swinging rotating shaft 403A are adapted to those of the shaft hole. Among them, the first side surface and the second side surface of the swinging member 40 are parallel to each other.

[0036] To define the swinging range of the swinging member, continue to refer to Figure 2 and Figure 3 , the pressing plate 30 is also symmetrically provided with limiting portions 302. Extension pieces 404 extend from the first end surface and the second end surface of the swinging member 40 in the direction away from the first central axis line L1. Limiting grooves 405 cooperating with the limiting portions 302 are arranged on the extension pieces 404, so that the limiting portions 302 can be inserted into the limiting grooves 405, and the swinging member 40 can swing within a predetermined range by the height of the limiting portions 302. In this embodiment, the first end surface and the second end surface of the swinging member 40 are parallel to each other and perpendicular to the first side surface and the second side surface.

The connecting rod 201A is perpendicular to the surface of the key 20, and the hook 201B extends from the bottom end of the connecting rod 201A toward the key 20, and the included angle formed by the two is an acute angle. In practical applications, the materials of the connecting rod 201A and the hook 201B are both made of elastic materials.

[0038] To make the first engaging groove and the second engaging groove mechanism simple and better adapt to the key buckle, continue to refer to Figure 4, the first engaging groove 401 includes a first accommodating cavity 401A and a first abutting portion 401B, the second engaging groove 402 includes a second accommodating cavity 402A and a second abutting portion 402B. Both the first accommodating cavity 401A and the second accommodating cavity 402A are close to the pressing plate 30. The first abutting portion 401B of the first engaging groove 401 extends from the first end face towards the inside of the groove of the first engaging groove 401, and the second abutting portion 402B of the second engaging groove 402 extends from the second end face towards the inside of the groove of the second engaging groove 402. The first abutting portion 401B includes a first guiding surface 401B1, a first abutting surface 401B2 and a first engaging bottom surface 401B3. The second abutting portion 402B includes a second guiding surface 402B1, a second abutting surface 402B2 and a second engaging bottom surface 402B3. The first guiding surface 401B1 is located at the top of the first abutting portion 401B, and the second guiding surface 402B2 is located at the top of the second abutting portion 402B. Both the first abutting surface 401B2 and the second abutting surface 402B2 are perpendicular to the pressing plate 30. The first guiding surface 401B1 and the first abutting surface 401B2 intersect, and the second guiding surface 402B1 and the second abutting surface 402B2 intersect. The first engaging bottom surface 401B3 is smoothly connected to the first abutting surface 401B2, and the second engaging bottom surface 402B3 is smoothly connected to the second abutting surface 402B2.

[0039] In this embodiment, since the angle between the hook 201B and the connecting rod 201A is an acute angle, in order to better guide the key buckle into the engaging groove, the angle between the first guiding surface 401B1 and the first abutting surface 401B2 is an obtuse angle, and the angle between the second guiding surface 402B1 and the second abutting surface 402B2.

[0040] The heights of the first accommodating cavity 401A and the second accommodating cavity 402A are equal to the height of the hook 201B. The distance between the first abutting surface 401B2 and the second abutting surface 402B2 is equal to the distance between the fitting surfaces of the two connecting rods 201A. The two connecting rods 201A are respectively the connecting rods inserted into the first engaging groove 401 and the second engaging groove 402. The fitting surfaces of the two connecting rods 201A are the fitting surfaces where the connecting rod 201A fits with the first abutting surface 401B2 and the fitting surface where it fits with the second abutting surface 402B2.

[0041] The engaging process of the key buckle and the engaging groove in this embodiment is as follows:

[0042] The key buckles 201 corresponding to the first engaging groove 401 and the second engaging groove 402 are respectively introduced into the first engaging groove 401 and the second engaging groove 402 through the first guiding surface 401B1 and the second guiding surface 402B2. The first abutting portion 401B and the second abutting portion 402B respectively abut against the connecting rod 201A, causing elastic deformation of the key buckle 201. After the hook 201B slides away from the first abutting surface 401B2 and the second abutting surface 402B2, the first abutting portion 401B and the second abutting portion 402B no longer abut against the connecting rod 201A, and the hook 201B smoothly transitions to the first engaging bottom surface 401B3 and the second abutting surface 402B2, so that the first engaging bottom surface 401B3 and the second abutting surface 402B2 can catch the hook 201B, and the key buckle 201 completes the engagement with the first engaging groove 401 and the second engaging groove 402.

[0043] In order to further balance the key and prevent the key from shaking, a pair of key claws 202 are further provided on the surface of the key 20 facing the swinging member 40, and the key claws 202 are in clearance rotational fit with the corresponding key rotating shaft 301A.

[0044] In order to enable the key claws and the key rotating shaft to pivot better, the key claws 202 are made of an elastic material, and their shape is arc-shaped, and the arc length is greater than the semi-arc length thereof. The shape of the key rotating shaft 301A is arc-shaped, and the arc length is greater than the semi-arc length thereof. Among them, the radius of the key claws 202 is greater than the radius of the key rotating shaft 301A.

[0045] In summary, the above solution of the present application solves the problem of key shaking through the cooperation of the key buckles provided on the key and the engaging grooves provided on the swinging member, and realizes the balance during key pressing.
