[0020] 1 to 5, one embodiment of the present application provides a switch panel 100, which includes a mounting seat 10, a key member 20, two connecting seats 30, two reset assemblies 40, and two restraining members 50.

[0021] The key member 20 has two key portions 21, and the key member 20 is rotatably connected to the mounting seat 10, and one key portion 21 can bend or drop relative to another key portion 21. Each connecting seat 30 is provided with one key portion 21 projecting from the mounting seat 10, and the connecting seat 30 includes two first connecting arms 31 spaced apart. 6 , the swinging member 41 includes a first swinging portion 411 and a second swinging portion 412, the first swinging portion 411 being disposed between the two first connecting arms 31, the second swinging portion 412 being disposed at one end of the first swinging portion 411 away from the other reset assembly 40, a strip-shaped through-hole 413 extending to the second swinging portion 412 being disposed in the first swinging portion 411, the connecting shaft 42 rotatably passing through the strip-shaped through-hole 413 and connected between the two first connecting arms 31, and as can be understood, the connecting shaft 42 can move within the strip-shaped through-hole 413. The resetting member 43 is fitted onto the outside of the first swinging portion 411, and both ends of the resetting member 43 are pre-compressed so as to abut between the connecting shaft 42 and the second swinging portion 412. For example, the reset member 43 may be a spring or an elastic sleeve. The locking member 50 includes a first locking portion 51 and a second locking portion 52. When viewed along the rotation direction of the key member 20, the first locking portion 51 is connected between the spaced-apart mounting seat 10 and the second locking portion 52 to jointly form a locking space; that is, the locking space is located on one side of the second locking portion 52 that is away from the key member 20. For example, the second locking portion 52 may be protruded from the tip of the first locking portion 51. The second swing portion 412 of each reset assembly 40 is rotatably locked within the locking space.

[0022] In concrete use, when one key part 21 is pressed downward, the connecting seat 30 and the connecting shaft 42 cooperate to rotate the end of the first swing part 411 at the bottom away from the second swing part 412 downward, and at this time, the restraining space prevents the second swing part 412 from moving horizontally and upward, causing it to leave the restraining space. At this time, the elastic biasing force accumulated by the pre-compression of the reset member 43 of the other reset assembly 40 presses the swing part 41 to rotate upward, thereby supporting the bending of the other key part 21. The pressed key part 21 can be used to trigger the on or off state of the switch panel 100. Similarly, when the bent other key part 21 is pressed, the key member 20 can be used to trigger the off or on state of the switch panel 100.

[0023] In the present application, two reset assemblies 40 are provided with a rocker member 41, a connecting shaft 42, and a reset member 43 that cooperate to allow the rocker member 41 of one reset assembly 40 to be positioned horizontally, while the rocker member 41 of another reset assembly 40 can be bent, thereby reducing the horizontal space occupied by all reset assemblies 40 and similarly avoiding the vertical volume being too large when two rocker members 41 are installed vertically stacked at the same time. Therefore, the switch panel 100 provided by the present application can improve the balance of size in each direction, which is advantageous in improving the flexibility of use of the switch panel 100.

[0024] 5 to 7, in some embodiments, the second swinging part 412 has a first arc-shaped end surface 4120 curved away from the first swinging part 411, the end surface of the first securing part 51 facing the securing space has a first arc-shaped region 510, the first arc-shaped region 510 is adjacent to the mounting seat 10, the second securing part 52 has a second arc-shaped end surface 520 facing the securing space, the curvature of the first arc-shaped region 510 and the second arc-shaped end surface 520 matches the curvature of the first arc-shaped end surface 4120, so that the first arc-shaped end surface 4120 can rotate along the curved surface formed by the first arc-shaped region 510 and the second arc-shaped end surface 520 together, thereby realizing the second swinging part 412 being rotatably secured within the securing space. The engagement of the first arc-shaped region 510, the first arc-shaped end surface 4120 and the second arc-shaped end surface 520 can reduce the frictional force that the second oscillating part 412 experiences when rotating, thereby reducing the force required for the switch panel 100 to switch between switch states, which is advantageous in improving the comfort of using the switch panel 100.

[0025] In some embodiments, the first retaining portion 51 has two first arc-shaped regions 510 spaced apart, and the projection of the second retaining portion 52 is located between the two first arc-shaped regions 510, and reducing the size setting of the second retaining portion 52 is advantageous in further reducing the frictional force experienced when the second swing portion 412 rotates, thereby further improving the comfort of use of the switch panel 100.

[0026] In another embodiment, the number of the first arcuate region 510 may be one, and the second arcuate end surface 520 may be connected to the first arcuate region 510 at a transitional portion having the same width.

[0027] In some embodiments, a first accommodating groove 101 is provided in the mounting base 10, the retaining member 50 is provided in the first accommodating groove 101, and the first retaining portion 51 is connected to the bottom wall of the first accommodating groove 101 and the second retaining portion 52 spaced apart, and the first accommodating groove 101 is advantageous in further reducing the vertical volume of the switch panel 100.

[0028] In some embodiments, two second receiving grooves 102 are recessed into the bottom wall of the first receiving groove 101, and each second receiving groove 102 is adjacent to the first arc-shaped region 510 of the first fastening portion 51. The second receiving groove 102 has a second arc-shaped region 1021 adjacent to the first arc-shaped region 510, and the curvature of the second arc-shaped region 1021 matches the curvature of the first arc-shaped end surface 4120, so that the first arc-shaped end surface 4120 can rotate along a curved surface jointly formed by the first arc-shaped region 510, the second arc-shaped end surface 520, and the second arc-shaped region 1021. The second receiving grooves 102 are advantageous in further reducing the vertical volume of the switch panel 100.

[0029] In some embodiments, a third accommodating groove 103 is recessed into the bottom wall of the second accommodating groove 102, and the third accommodating groove 103 is used to accommodate a portion of the reset member 43. The third accommodating groove 103 can be extended and widened in a direction away from the second arc-shaped region 1021, and the third accommodating groove 103 can also further reduce the vertical volume of the switch panel 100.

[0030] 5 and 6, in some embodiments, the strip-shaped through hole 413 includes a first hole portion 4131 and a second hole portion 4132 that are connected to each other, the connecting shaft 42 passes through the first hole portion 4131, the diameter of the first hole portion 4131 is larger than the diameter of the portion of the second hole portion 4132 that is adjacent to the first hole portion 4131, and the second hole portion 4132 passes through the first swing part 411 and is spaced apart from the end face of the second swing part 412, the structure of the strip-shaped through hole 413 not only ensures the connection stability of the connecting shaft 42 but also is advantageous in reducing the occurrence of irregular cracks caused by stress concentration when the connecting shaft 42 abuts against the strip-shaped through hole 413 during swing of the first swing part 411 of the swing part 411, and therefore the structure of the strip-shaped through hole 413 is advantageous in further improving the service life of the swing part 41.

[0031] In another embodiment, the strip-shaped through-hole 413 may be disposed without penetrating the end surface of the first swinging portion 411 , and the strip-shaped through-hole 413 may include only the first hole portion 4131 .

[0032] 4 and 5 , in some embodiments, the switch panel 100 further includes a rotating seat 60 and two spaced-apart second connecting arms 70, where the rotating seat 60 is installed on the bottom wall of the first receiving groove 101 and the rotating seat 60 is installed between the two second receiving grooves 102. The second connecting arms 70 protrude from the bottom wall of the first receiving groove 101 and are attached to the key member 20. A rotating shaft 61 is installed on one of the rotating seat 60 and the second connecting arm 70, and a connecting hole 71 is installed on the other. In this embodiment, the rotating shafts 61 are installed on two end surfaces of the rotating seat 60 perpendicular to the arrangement direction of the two locking members 50, and the connecting holes 71 are installed in each second connecting arm 70. The rotating shafts 61 are rotatably installed in the connecting holes 71, thereby realizing the key member 20 being rotatably connected to the mounting seat 10. The rotation method of the present invention has a simple structure, and is advantageous in that the rotation seat 60 is installed on the bottom wall of the first receiving groove 101, thereby further reducing the vertical volume of the switch panel 100.

[0033] In another embodiment, the key member 20 can be rotatably connected to the mounting seat 10 by a hinge connection or a universal ball rotation.

[0034] 3 and 5, in some embodiments, the switch panel 100 further includes a switch assembly 80, which is mounted on the mounting seat 10 and is mounted relative to one key portion 21, and which is located beside one reset assembly 40, and which can switch the switch state of the switch assembly 80 when one of the key portions is pressed. Illustratively, the switch assembly 80 can include either a stroke switch or a microswitch.

[0035] For example, a trigger portion 81 may be provided on an end surface of one key portion 21 facing the mounting seat 10. For example, the trigger portion 81 may have an L-shaped structure, and the trigger portion 81 may be used to press or pull up a portion of the switch assembly 80 to switch the switch state of the switch assembly 80. In another embodiment, the shape of the end surface of the key portion 21 facing the mounting seat 10 may be modified, for example, provided with a convex curved surface, so that when the key portion 21 is pressed, the most curved part of the convex curved surface presses the switch assembly 80 to switch the switch state of the switch assembly 80. For example, the switch assembly 80 may be installed within the mounting seat 10, and the switch assembly 80 may be exposed on one side of the mounting seat 10 facing the key member 20 through an opening 104. In this embodiment, the opening 104 penetrates the bottom wall of the first receiving groove 101.

[0036] 1 and 5 , in some embodiments, the mounting seat 10 includes a first seat portion 11 and a second seat portion 12 that are removably connected, and the retaining member 50 is installed in the first seat portion 11. Accordingly, the first receiving groove 101, the second receiving groove 102, and the third receiving groove 103 may all be installed in the first seat portion 11. The switch assembly 80 can be installed in the second seat portion 12. For example, a locking hook 22 is installed in one of the first seat portion 11 and the second seat portion 12, and a locking hole 105 is installed in the other, and the locking hook 22 is engaged in the locking hole 105 to realize the removably connection between the first seat portion 11 and the second seat portion 12.

[0037] In some embodiments, the second seat 12 includes a first portion 121 and a second portion 122 that are removably connected to each other. The second portion 122 is located closer to the first seat 11 than the first portion 121. For example, the first portion 121 and the second portion 122 can be connected to each other with screws. The connected first and second portions 121 and 122 can collectively form a housing, allowing a circuit element 82 to be installed in the housing to enhance the functionality of the switch panel 100. For example, the circuit element 82 can be electrically connected to the switch assembly 80, allowing the switch assembly 80 to switch the circuit element 82 between conductive and non-conductive states. For example, the switch panel 100 with the integrated circuit element 82 can also function as an electronic doorbell or a light dimmer. The structure of the second seat 12 is advantageous for improved ease of installation and removal.

[0038] 1 , in some embodiments, at least two terminal blocks 13 (two terminal blocks 13 are shown in the figure) are installed at one end of the mounting seat 10 away from the key member 20, and illustratively, the terminal blocks 13 can be electrically connected to the circuit element 82. The switch panel 100 further includes a junction box 90 and an isolation member 91. The junction box 90 is installed away from the key member 20, and the junction box 90 and the mounting seat 10 jointly form a cavity. The junction box 90 has at least two ports 901, illustratively, the number of ports 901 may be the same as the number of terminal blocks 13, and illustratively, the ports 901 may be drilled holes or knock holes. The isolation member 91 is connected to the mounting seat 10, illustratively, the isolation member 91 is detachably connected to the mounting seat 10, and illustratively, the isolation member 91 can be attached to the mounting seat 10 by an engagement manner. The isolation member 91 is installed in the cavity to divide the cavity into different sections, and at least two terminal blocks 13 are exposed to the different sections, and each port 901 is used to insert a cable to be electrically connected to the terminal block 13.
