[0027] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0028] The present application provides a panel switch, such as Figure 1-Figure 6As shown, it includes a pressing panel 10, a transmission arm 30 and a base 40. The pressing panel 10 is slidably arranged on the base 40. The transmission arm 30 is arranged between the base 40 and the pressing panel 10. The transmission arm 30 includes a movable connection part 31, a rotating connection part 32 and a pressing part 33. The movable connection part 31 is movably connected to the base 40, the rotating connection part 32 is rotatably connected to the pressing panel 10, and the pressing part 33 is arranged on a side of the rotating connection part 32 away from the movable connection part 31. Figure 3A and Figure 3B ,in Figure 3A is a schematic diagram of the cross-sectional structure of the panel switch when the panel 10 is pressed to reset. Figure 3B The cross-sectional structure diagram of the panel switch when the pressing panel 10 is pressed down is shown in FIG. When the pressing panel 10 is not subjected to external pressing force, the pressing panel 10 and the rotating connection part 32 and the pressing part 33 of the transmission arm 30 are located at relatively high positions. When the pressing panel 10 is pressed down by external force, since the rotating connection part 32 is rotatably connected to the pressing panel 10, when the transmission arm 30 rotates around the rotating connection part 32, the height of the rotating connection part 32 itself will also drop, causing the pressing part 33 to drop quickly. The panel switch has a better pressing effect.

[0029] In some optional embodiments, when the pressing panel 10 drops 2mm-3mm, the height of the pressing portion 33 drops 4mm-8mm. Here, the height of the pressing portion 33 drops can be specifically understood as the height of the lower edge of the pressing portion 33 away from the movable connecting portion 31.

[0030] In some embodiments, an elastic member 20 suitable for resetting the pressing panel 10 is further included, and the elastic member 20 is disposed between the pressing panel 10 and the transmission arm 30. The arrangement of the elastic member 20 enables the pressing panel 10 to automatically slide upwards and reset.

[0031] In some embodiments, the elastic member 20 is a spring, which is arranged between the movable connection part 31 and the rotating connection part 32, and the transmission arm 30 and the pressing panel 10 are provided with a mounting groove 3a or a mounting column 111 suitable for installing the spring. In a specific embodiment, the transmission arm 30 is provided with a mounting groove 3a, and the pressing panel 10 is provided with a mounting column 111, one end of the spring is suitable for inserting into the mounting groove 3a, and the other end is suitable for being sleeved outside the mounting column 111. The spring has low cost of use, simple installation method, and is easy to assemble or replace. In other embodiments, the elastic member 20 can also be set as a torsion spring, and the torsion spring can be set along the same virtual rotation axis with the rotating connection part 32. In some other embodiments, the elastic member 20 can also be set as a tension spring, and the tension spring is located between the rotating connection part 32 and the pressing part 33.

[0032] In some embodiments, the movable connection part 31 extends to two opposite sides of the transmission arm 30 in a direction parallel to the rotation axis of the rotating connection part 32 to increase the connection strength and improve the movement stability of the movable connection part 31. Specifically, the movable connection part 31 can be set as two spaced protrusions, and the two protrusions are respectively arranged on two opposite sides of the transmission arm 30 in a direction parallel to the rotation axis of the rotating connection part 32, and the base 40 is provided with a limiting groove 4a corresponding to the protrusion. In other embodiments, the movable connection part 31 can also be set as more than two spaced protrusions. In some other embodiments, the movable connection part 31 can also be set as a plate body continuously arranged in a direction parallel to the rotation axis of the rotating connection part 32. In addition, it is obvious that the movable connection part 31 can also be set in the form of a limiting groove 4a, and a structure corresponding to the limiting groove 4a is set on the base 40.

[0033] In some embodiments, the rotating connection portion 32 extends to two opposite sides of the transmission arm 30 along a direction parallel to the rotation axis of the rotating connection portion 32 to increase the connection strength and improve the rotation stability of the transmission arm 30 .

[0034] In some embodiments, the rotating connection part 32 includes hinge shafts protruding from two opposite sides of the transmission arm 30 in a direction parallel to the rotation axis of the rotating connection part 32, and a hinge seat 112 protruding downward to mount the hinge shaft is provided on the pressing panel 10. In other embodiments, it is obvious that the hinge seat 112 can also be provided on the rotating connection part 32, and the corresponding hinge shaft can be provided on the pressing panel 10.

[0035] In some embodiments, the transmission arm 30 is provided with a first abutting surface 301 and a second abutting surface 302 on a side facing the pressing panel 10, and a third abutting surface 303 and a fourth abutting surface 304 on a side facing away from the pressing panel 10. The first abutting surface 301 and the second abutting surface 302 are arranged to intersect with each other so as to be adapted to alternately abut against the pressing panel 10. The third abutting surface 303 is arranged below the first abutting surface 301 and is parallel to the second abutting surface 302, and the fourth abutting surface 304 is arranged below the second abutting surface 302 and is parallel to the first abutting surface 301. Specifically, when the pressing panel 10 is reset, the first abutting surface 301 is suitable for abutting the bottom surface of the pressing panel 10, and the fourth abutting surface 304 abuts on the base 40. When the pressing panel 10 is pressed downward, the first abutting surface 301 tilts away from the bottom surface of the pressing panel 10, and the second abutting surface 302 abuts on the bottom surface of the pressing panel 10. At this time, the third abutting surface 303 is parallel to the second abutting surface 302 and is in a horizontal or approximately horizontal state.

[0036] In some embodiments, two or more transmission arms 30 are arranged at intervals, and the effective pressing area of ​​the pressing panel 10 is expanded by increasing the number of transmission arms 30. Specifically, four transmission arms 30 can be arranged, and the four transmission arms 30 are respectively arranged relative to the four corners of the pressing panel 10, so that the middle and surrounding of the pressing panel 10 form an effective pressing area.

[0037] In some embodiments, the peripheral side of the pressing panel 10 and the peripheral side of the base 40 are interlocked with each other to guide the pressing panel 10 to slide up and down. Specifically, the pressing panel 10 includes a panel body 11 and a first side plate 12, a second side plate 13, a third side plate 14, and a fourth side plate 15 which are sequentially arranged around the peripheral side of the panel body 11. The base 40 includes a first side portion 41, a second side portion 42, a third side portion 43, and a fourth side portion 44 which are sequentially arranged. The first side plate 12 and the third side plate 14 are respectively suitable for being embedded in the inner side of the first side portion 41 and the third side portion 43, and the second side plate 13 and the fourth side plate 15 are respectively suitable for covering the outer side of the second side portion 42 and the fourth side portion 44, thereby limiting the position of the pressing panel 10 in the horizontal direction so that the pressing panel 10 can only slide up and down.

[0038] In some embodiments, a limiting structure for limiting the sliding stroke of the pressing panel 10 is also provided between the pressing panel 10 and the base 40. Specifically, the limiting structure can be provided between the side plate of the pressing panel 10 and the side of the base 40, for example, between the first side plate 12 and the first side portion 41. The bottom surface of the first side plate 12 is suitable for contacting the first side portion 41, thereby limiting the maximum distance that the pressing panel 10 slides downward. Further, a positioning protrusion 141 can be provided on the first side plate 12, and a corresponding positioning groove 41a can be provided on the first side portion 41. The positioning protrusion 141 is slidably provided in the positioning groove 41a in the up-down direction to further guide the sliding direction of the pressing panel 10. The structure of the third side plate 14 can be symmetrical with that of the first side plate 12, and the structure of the third side portion 43 can be symmetrical with that of the first side portion 41.

[0039] As a supplement, a plurality of limiting grooves 4a on the base 40 for movably connecting the transmission arm 30 can be arranged on the second side portion 42 and the fourth side portion 44, staggered with the first side plate 12 and the third side plate 14 to make the layout more reasonable and compact.

[0040] In some embodiments, a downward extending buckle 113 is provided on the pressing panel 10, and a corresponding slot 42a is provided on the second side 42 and / or the fourth side 44 of the base 40. The buckle 113 and the slot 42a can realize a detachable connection while also cooperating to limit the maximum height of the pressing panel 10 sliding upward, thereby preventing the pressing panel 10 from detaching upward from the base 40.

[0041] In some embodiments, it also includes a mounting plate 50 suitable for mounting the base 40 on a structure such as a wall or a cabinet. The mounting plate 50 is provided with mounting holes 5a suitable for installing fasteners. The mounting plate 50 is detachably connected to the base 40, and an avoidance space 3b suitable for avoiding the fasteners is provided on the base 40 and / or the transmission arm 30.
