[0002] A switch panel refers to a unit that uses a combination of a control board and electronic components and programming to achieve intelligent circuit switch control. It has multiple functional features, is safe to use, and has beautiful designs.

[0003] At present, in the field of smart home, there are many long-button switch panel designs, including large-button panels, double-button panels, and three-button panels. When the trigger switch is set in the middle of the panel, the edge of the button panel is pressed, and the pressed position is locally stressed. After the local stress is applied, the pressure is low in some places and high in other places, so that the force cannot be evenly transmitted to the entire panel, that is, the force cannot be transmitted to the middle trigger switch area. This phenomenon seriously reduces the user experience. Especially with the rapid development of smart home panels, high-end products are designed to be ultra-thin, and the travel of the panel is also very limited, which aggravates the occurrence of such undesirable phenomena.

[0033] Embodiment 1

[0034] refer to Figure 1-4 , a switch panel that can be triggered by edge pressing, comprising:

[0035] A fixing seat 1 and a fixing member 2, wherein the fixing member 2 is covered on the fixing seat 1, a space between the fixing seat 1 and the fixing member 2 forms a receiving cavity, and the fixing member 2 is provided with a plurality of key exposure slots 201;

[0036] A main control board 3 is disposed in the accommodating cavity. The main control board 3 is provided with a plurality of buttons 301, and each of the buttons 301 is respectively disposed in the button exposure groove 201;

[0037] In this embodiment, by coordinating the arrangement positions of the key exposure groove 201 and the key 301 , the key 301 can protrude from the key exposure groove 201 , so that the key 301 can be pressed by the key plate 4 at the upper end of the key 301 .

[0038] A plurality of key plates 4 are arranged on the upper surface of the fixing member 2, and the keys 301 are respectively arranged in the middle of the key plates 4. The key plates 4 can press the keys 301 when they move downward;

[0039] In this embodiment, the key exposure slot 201 is disposed at a lower position corresponding to the middle of the key plate 4. One fixing member 2 may correspond to one or more key plates 4.

[0040] A plurality of balancing rods 5, at least one balancing rod 5 is connected between each of the key plates 4 and the fixing member 2;

[0041] A plurality of X-shaped brackets 6 are provided, with at least two X-shaped brackets 6 being arranged between each of the key panels 4 and the fixing member 2, the lower ends of the X-shaped brackets 6 being connected to the fixing member 2, an elastic member 7 being arranged in the middle of the X-shaped brackets 6, and the upper end face and the lower end face of the X-shaped bracket 6 remaining parallel during the process of the X-shaped bracket 6 being pressed or released.

[0042] In this embodiment, a key panel 4 is jointly supported by multiple X-shaped brackets 6, and the upper and lower end surfaces of the X-shaped brackets 6 are kept parallel. The middle of the X-shaped bracket 6 is hinged. When the edge of the key panel 4 is pressed, the edge of the key panel 4 will transfer the force to one of the upper ends of the X-shaped bracket 6, and then transfer the force to the other upper end of the X-shaped bracket 6 through the structure of the X-shaped bracket 6, and then transfer it to other X-shaped brackets 6 through the corresponding X-shaped bracket 6. Therefore, when the edge of the key panel 4 is subjected to force, the upper end surfaces of all the X-shaped brackets 6 sink at the same time, thereby transferring the edge force to the central position of the key panel 4, pressing down the key 301.

[0043] The X-shaped bracket 6 and the balance bar 5 of this embodiment connect the key panel 4 and the fixing member 2. The fixing member 2 does not move relative to the fixing base 1. When any position of the key panel 4 is pressed, the key panel 4 moves downward as a whole under the linkage of the balance bar 5 and the X-shaped bracket 6, so that the key panel 4 presses the key 301 and triggers the function of the key 301.

[0044] Furthermore, the bottom surface of the key panel 4 is provided with a plurality of first circular grooves 401 , which are connected to the upper end of the balance bar 5 , and the upper end surface of the fixing member 2 is provided with a plurality of first sliding grooves 202 , which are connected to the bottom end of the balance bar 5 .

When the top end of the balance bar 5 rotates on the key board 4, the bottom end of the balance bar 5 slides in the first sliding groove 202 of the fixing member 2, so that the key board 4 can be kept balanced.

[0046] Furthermore, the elastic member 7 is one or more of a spring, an elastic arm, a spring sheet, and foam.

[0047] Furthermore, the elastic member 7 is a tower spring, and the narrow end of the tower spring is arranged on the fixing member 2 .

[0048] In this embodiment, a tower spring is designed in the middle of each X-shaped bracket 6 for rebounding the key plate 4 to avoid the key 301 from having insufficient rebound force to support the entire key plate 4, and at the same time, it is conducive to the stability of the key plate 4. The narrow circle of the tower spring is fixed to the fixing member 2, and the wide part is used to support the key plate 4, which greatly reduces the spring force that needs to be overcome when pressing the key plate 4, and improves the pressing feel.

[0049] Furthermore, the bottom surface of the key panel 4 is provided with a second circular groove 402 and a second sliding groove 403 corresponding to the X-shaped bracket 6, one of the top ends of the X-shaped bracket 6 is connected to the second circular groove 402, and the other top end of the X-shaped bracket 6 is connected to the second sliding groove 403, and the fixing member 2 is provided with a third sliding groove 203 corresponding to the X-shaped bracket, and the bottom end of the X-shaped bracket 6 is connected to the third sliding groove 203.

[0050] Through this structure, the upper end surface and the lower end surface of the key plate 4 are respectively connected to the key plate 4 and the fixing member 2, so that during the up and down movement of the key plate 4, the key plate 4 always remains parallel to the fixing member 2, limiting the moving direction of the key plate 4.

[0051] Furthermore, the X-shaped bracket 6 is arranged at four corners of the lower end surface of the key board 4 .

[0052] Furthermore, there are two balancing rods 5 , and the top ends of the balancing rods 5 are respectively wound around the left and right sides of the key board 4 .

[0053] Furthermore, the balance bar 5 is a U-shaped structure.

[0054] This structure can support the four corners and the left and right sides of the lower end surface of the key board 4, and is suitable for the key board 4 with a square structure.
