Description

Technical Field

[0001] This utility model relates to a switch, specifically to a pressing structure and a thin-walled switch having the pressing structure. Background Technology

[0002] Currently, wall switches are electrical switches installed on walls, serving as both decorative home appliances and electrical components for connecting and disconnecting circuits. Rocker wall switches on the market operate on the principle of tilting up and down or swinging left and right. When the switch is not pressed, the switch panel tilts to one side; when pressed, it tilts to the other side, always resulting in one side being higher than the flat surface, making the switch surface uneven. This characteristic of rocker switches makes them prone to dust accumulation, causing edge jamming and affecting visual aesthetics, failing to meet modern aesthetic demands. Therefore, flush wall switches (flat wall switches) have begun to appear on the market. While these flush wall switches mostly achieve a completely flat or slightly tilting button, their self-resetting drive mechanism has a more complex structure, more components, poorer transmission stability, and unstable pressing transmission at the panel, making them prone to failure. Furthermore, to ensure the swing distance of the lever, existing switches typically require a sufficiently long travel distance for the panel, resulting in a longer panel and a thicker overall product. Utility Model Content

[0003] To address the problems of complex pressing structures and poor transmission stability in existing switches in the background art, this utility model provides a pressing structure and a thin-walled switch equipped with the pressing structure.

[0004] The technical solution of this utility model is: a pressing structure, including a mounting bracket, and further comprising:

[0005] A panel is mounted on a mounting frame, and the panel is movably connected to the mounting frame.

[0006] A transmission plate is disposed on the panel. The transmission plate includes a pressing part, a bearing part, and a rotating part. The panel presses the bearing part to make the pressing part rotate relative to the rotating part. The distance from the bearing part to the rotating part is less than the distance from the pressing part to the rotating part.

[0007] As a further improvement of this utility model, the horizontal height of the pressure-bearing part is higher than the horizontal height of the rotating part.

[0008] As a further improvement of this utility model, the pressing part and the rotating part are respectively located at both ends of the transmission plate, and the pressure bearing part is provided with a protrusion, which is arranged in an arc shape.

[0009] As a further improvement of this utility model, there are two transmission plates, both of which are located below the panel. The pressing parts of the two transmission plates are arranged opposite to each other and are used to drive the swing arm to swing.

[0010] As a further improvement of this utility model, the transmission plate and the panel are connected by a shaft and a hole, and the mounting bracket has a groove formed by a downward indentation on the upper surface of the rotating part.

[0011] As a further improvement of this utility model, the mounting bracket is provided with a notch, and the transmission plate is provided with an elastic part that matches the notch. The elastic part provides elastic force after the transmission plate is pressed.

[0012] As a further improvement of this utility model, the mounting bracket is provided with a positioning groove, the elastic part is bent into a U-shape, and one end of the elastic part is provided with a positioning block that matches the positioning groove.

[0013] As a further improvement of this utility model, the panel and the mounting bracket are connected by hooks and slots, and the panel and the mounting bracket slide vertically and are limited by the hooks and slots.

[0014] As a further improvement of this utility model, the mounting bracket is provided with a receiving groove and a guide groove, and the panel is provided with an edge that matches the receiving groove and a guide post that matches the guide groove.

[0015] A thin-walled panel includes a movable contact, a conductive sheet, a rocker arm, a pressure plate, a reset component, and the aforementioned pressing structure. The panel causes the pressure plate to move vertically when pressed. The pressure plate is connected to the rocker arm, which swings to engage or disengage the movable contact with the conductive sheet, thus enabling the circuit to be connected or disconnected. The reset component abuts against the pressure plate for resetting the pressure plate.

[0016] The beneficial effects of this utility model are that the movement of the panel relative to the mounting bracket reliably activates the transmission plate, which in turn reliably drives the swing arm to its position, thereby reliably activating the moving contact and achieving circuit connection or disconnection. This utility model also has advantages such as simple structure, convenient and reliable transmission, easy assembly, and long service life. Attached Figure Description

[0026] The embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0027] Depend on Figure 1 Combination Figures 2-8 As shown, a pressing structure includes a mounting bracket 1, and further includes:

[0028] Panel 2 is mounted on mounting frame 1, and panel 2 is movably connected to mounting frame 1;

[0029] A transmission plate 3 is disposed on the panel 2. The transmission plate 3 includes a pressing part 31, a bearing part 32, and a rotating part 33. The panel 2 presses the bearing part 32, causing the pressing part 31 to rotate relative to the rotating part 33. The distance from the bearing part 32 to the rotating part 33 is less than the distance from the pressing part 31 to the rotating part 33. The beneficial effect of this invention is that the movement of the panel relative to the mounting bracket reliably activates the transmission plate, reliably driving the swing arm to its position, thus reliably activating the moving contact piece and achieving circuit connection or disconnection. This invention also has the advantages of simple structure, convenient and reliable transmission, easy assembly, and long service life.

[0030] The horizontal height of the pressure-bearing part 32 is higher than that of the rotating part 33. Specifically, the pressing part 31 and the rotating part 33 are respectively located at both ends of the transmission plate 3. The pressure-bearing part 32 is provided with a protrusion 34, which is arc-shaped. This structure allows the pressing part to rotate through the pressure-bearing part when the panel is touched and pressed. Utilizing the lever amplification principle, the small displacement of the panel is converted into a long displacement of the pressing part, thereby ensuring the swing amount of the swing arm. This minimizes the panel protrusion, reduces the product thickness, and achieves an ultra-thin design.

[0031] There are two transmission plates 3, both located below the panel 2. The pressing parts 31 of the two transmission plates 3 are arranged opposite each other and are used to drive the swing arm 6 to swing. This structure allows the transmission plates to move when the panel is pressed at any position, thereby causing the swing arm to swing and switch the moving contact piece, resulting in a better user experience.

[0032] The transmission plate 3 and the panel 2 are connected by a shaft 35 and a hole 21. The mounting bracket 1 has a recessed groove 11 on its upper surface at the rotating part 33. The shaft and hole facilitate the integrated assembly of the transmission plate and the panel, resulting in a simple structure and convenient and reliable assembly. The groove facilitates the adjustment and testing of the transmission plate, making the product transmission more stable and reliable.

[0033] The mounting bracket 1 has a notch 12, and the transmission plate 3 has an elastic part 36 that matches the notch 12. The elastic part 36 provides elastic force when the transmission plate 3 is pressed. Specifically, the mounting bracket 1 has a positioning groove 13, and the elastic part 36 is bent into a U-shape. One end of the elastic part 36 has a positioning block 37 that matches the positioning groove 13. The cooperation between the positioning block and the positioning groove facilitates the installation of the transmission plate, making product assembly simple and convenient. The elastic part provides a certain restoring force, which can assist the transmission plate in resetting. In fact, the transmission plate can be mainly reset by the reset component and the pressure plate.

[0034] The panel 2 and mounting bracket 1 are connected via hooks 22 and slots 14. The panel 2 and mounting bracket 1 slide vertically together and are limited by the engagement of hooks 22 and slots 14. Specifically, the mounting bracket 1 is provided with a receiving slot 15 and a guide slot 16, and the panel 2 is provided with an edge 23 that matches the receiving slot 15 and a guide post 24 that matches the guide slot 16. This structure makes panel installation convenient, the structure simple, the panel runs smoothly and reliably, avoids displacement, improves the overall integrity of the product, eliminates the need for other components such as faceplates, and provides a high level of protection.

[0035] A thin-walled switch includes a moving contact 4, a conductive sheet 5, a rocker arm 6, a pressure plate 7, a reset element 8, and the aforementioned pressing structure. The panel 2, when pressed, causes the pressure plate 7 to move vertically. The pressure plate 7 is connected to the rocker arm 6, causing the rocker arm 6 to swing and engage or disengage the moving contact 4 with the conductive sheet 5, thus connecting or disconnecting the circuit. The reset element 8 abuts against the pressure plate 7 to reset it. This structure makes the product simple, the operation convenient and reliable, and the switch can be quickly and reliably reset.
