Description

Technical Field

[0001] This utility model relates to switch panels, and more particularly to a spring arm structure on a switch panel. Background Technology

[0002] Electronic switch panels offer superior aesthetics and more diverse designs, adapting well to various design styles. With the increasing prevalence of smart devices, electronic switch panels are gaining popularity and attention. An electronic switch panel primarily consists of a base box, a circuit board, a touch switch mounted on the circuit board, and a button panel for actuating the touch switch. To allow the button panel to be moved away from the touch switch when not in use, a flexible arm is installed on the base box. This arm allows for deformation to meet the button's needs while also enabling the button panel to be pushed open.

[0003] The elastic arm on the existing electronic switch panel is long and strip-shaped, and is located opposite the corner of the button panel. However, when the user presses the button panel, the force applied is not necessarily perpendicular to the button panel. When the lateral force is large, the button panel may slide a short distance relative to the base box, creating the illusion that the button panel is "loose" and bringing a bad user experience. Utility Model Content

[0004] The purpose of this invention is to provide a switch panel spring arm structure that can improve the installation strength of the keypad, thereby enhancing operational stability and user experience.

[0005] The elastic structure of the switch panel of this utility model includes a base box, a circuit board containing a touch switch, and a button plate for pressing the touch switch; a base frame is mounted on the base box, and several button plates are mounted on the base frame. A touch switch is installed on the circuit board at the position opposite to the center of each button plate. A clearance hole is provided on the base frame at the position opposite to each touch switch. An elastic spring arm is provided on the base frame at two opposite sides of each clearance hole. The spring arm includes an elastic rod fixed at one end to the base frame, and a support rod extending to both sides at the other end of the elastic rod. The support rod has a positioning hole. A pressure post is provided on the button plate at the position opposite to each support rod, and a positioning block is provided at the end of the pressure post that engages with the positioning hole.

[0006] The switch panel elastic structure of this utility model has a circuit board and a base frame installed sequentially on the front of the base box, i.e., the side facing the user. The button panel is also installed on the front of the base frame. The button panel can be set as needed, or multiple buttons can be set horizontally or vertically. These button panels divide the switch panel into several areas, and the base frame and circuit board are correspondingly divided into several areas. The circuit board has a touch switch installed at the center of each area. At the same time, T-shaped spring arms are set at the middle of the upper and lower sides or the middle of the left and right sides of each area. The top two ends of the T-shape of each spring arm, i.e., each support rod, are provided with positioning holes, forming a structure of two spring arms and four positioning holes. Correspondingly, the inner side of the button panel has a pressure post that presses each support rod, and the pressure post also has a positioning block that fits into the positioning hole. This switch panel structure, on the one hand, uses positioning holes and positioning blocks to position the spring arm and the button panel relative to each other, so that the button panel will not be loose when the user presses it, thus effectively improving the user experience; on the other hand, the T-shaped spring arm is set in the middle of both sides of each area rather than at the corners, which can provide a higher reset force for the button panel, thereby improving the working stability of the switch panel.

[0007] Preferably, the base frame has spring arm holes that are consistent with the shape of the spring arms at the positions opposite to each spring arm; the elastic rod of the spring arm extends out parallel to the outer side of the base frame, and the support rod is installed on the outer side of the end of the elastic rod and protrudes out of the spring arm hole.

[0008] Preferably, four locking blocks are provided on the base frame opposite to each keypad. Each locking block has a locking groove, and each keypad has a hook connected to the locking groove. The thickness of the hook in the direction perpendicular to the keypad is less than the length of the locking groove in that direction.

[0009] Preferably, the four locking blocks are respectively disposed at the opposite ends of the support rods of the two spring arms.

[0010] Preferably, the base frame is divided into several areas relative to each button panel, and the base frame is provided with separator strips at the locations of adjacent areas.

[0011] Preferably, the outer side of the button panel is fitted with a decorative panel.

[0012] By designing the aforementioned flexible structure for the switch panel, the accuracy, stability, and aesthetics of the switch panel's operation can be further improved. Attached Figure Description

[0020] This utility model proposes an elastic structure for a switch panel.

[0021] The elastic structure of the switch panel in this embodiment includes a base box 1, a circuit board 2 containing a touch switch 3, and a button plate 4 for pressing the touch switch; there is also a base frame 5 mounted on the base box, and several of the aforementioned button plates are mounted on the base frame. A touch switch is respectively mounted on the circuit board at the position opposite to the center of each button plate. A clearance hole 51 is provided on the base frame at the position opposite to each touch switch. An elastic spring arm 6 is provided on the base frame at two opposite sides of each clearance hole. The spring arm includes an elastic rod 61 with one end fixed on the base frame, and a support rod 62 extending to both sides at the other end of the elastic rod, thereby forming a T-shaped structure. The support rod has a positioning hole 63. At the same time, a pressure post 7 is provided on the button plate at the position opposite to each support rod, and a positioning block 71 that engages with the positioning hole is provided at the end of the pressure post.

[0022] like Figure 1-5 As shown, the circuit board and base frame are sequentially mounted on the front of the base box, facing the user. The button panels are also mounted on the front of the base frame, with two buttons arranged horizontally and two vertically, forming a four-button structure. These four button panels divide the switch panel into four areas, and the base frame and circuit board are correspondingly divided into four areas as well. Each area has a touch switch mounted at its center, and T-shaped spring arms are positioned at the center of the left and right sides of each area. Each spring arm has positioning holes at both ends of its T-shape, providing each button panel with a double spring arm structure with four positioning holes. Correspondingly, each button panel has four pressure posts on its inner side, with positioning blocks that engage with the positioning holes. This switch panel structure effectively improves the operational stability of the switch panel and the user experience.

[0023] like Figure 5 As shown, the base frame 5 has spring arm holes 52 that are consistent with the shape of the spring arms at the positions opposite to each spring arm 6; the elastic rod 61 of the spring arm extends out from the plane parallel to the outer side of the base frame, that is, parallel to the surface of the keypad 4, and also parallel to the vertical plane of the wall when installed on the wall. The support rod 62 is installed on the outer side of the end of the elastic rod, that is, the side close to the keypad, so that it protrudes out of the spring arm hole, so that the bracket is closer to the keypad and connected to the keypad, and the spring arm can act more sensitively, thereby improving the accuracy and stability of connection and operation.

[0024] like Figure 1-3As shown, four locking blocks 8 are respectively provided on the base frame 5 opposite to each button panel. Each locking block has a locking groove 81, and each button panel 4 has a hook 9 connected to the locking groove. The thickness of the hook in the direction perpendicular to the button panel is less than the length of the locking groove in that direction, allowing the button panel to move along the locking groove to a certain extent without falling off, thus meeting the needs of button panel pressing and being popped open by the spring arms. The four locking blocks 8 are respectively set at the ends of the support rods of the two spring arms 6 opposite to each other, forming a more accurate fit with the spring arms. Meanwhile, the base frame 5 is divided into several areas relative to each button panel 4, and a separator strip 53 is provided at adjacent areas to ensure the stability of each button panel installation and to make each button panel independent, preventing operation of one button panel from interfering with the operation of others. In addition, a decorative panel 10 is installed on the outer side of the button panel 4 to improve the aesthetics of the switch panel.

[0025] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
