Description

Technical Field

[0001] The utility model relates to the technical field of switches. Background Art

[0002] In the prior art, many switch designs use a pressing plate to implement the opening and closing operations of the switch. However, during actual use, the pressing plate is prone to sagging after being pressed, that is, the pressing plate cannot return to its original position in time after being subjected to an external force. This sagging phenomenon not only affects the normal operating feel of the switch, but may also cause damage to the internal structure of the switch or shorten its service life. In addition, the sagging pressing plate may not provide clear operation feedback, resulting in the user being unable to confirm whether the switch is correctly opened or closed during operation. This problem is particularly prominent after the switch has been used for a long time. As time goes by, the reliability of the switch decreases, affecting the user experience. Therefore, how to avoid the sagging of the switch after being pressed is a problem existing in the prior art. Summary of the Utility Model

[0003] The utility model aims to provide a switch to at least solve or alleviate some of the problems existing in the prior art.

[0004] The utility model provides a switch, comprising: a frame, a switch function module, a pressing plate and an elastic member. The frame has a hollow portion. The switch function module is fixedly connected to the frame and has a return key provided corresponding to the hollow portion. The return key is configured to be movable between a pressing limit position and a return limit position in a first direction. The pressing plate is disposed on a side of the frame away from the switch function module, and the pressing plate is coupled to the return key. The elastic member is disposed on one of the frame and the pressing plate and abuts against the other of the frame and the pressing plate. The elastic member is configured to be deformable between a first limit position and a second limit position in the first direction, and when the return key is at the return limit position, the elastic member is between the first limit position and the second limit position.

[0005] According to the switch provided by the utility model, by providing an elastic member between the frame and the pressing plate, the elastic member can apply an upward external force to the pressing plate so that the pressing plate can return to its original position in time after being pressed and remain in a flat state. And when the return key is at the return limit position, that is, when the return key is basically not stressed, the pressing plate returns to its original position by using the elastic member between the first limit position and the second limit position. That is to say, the pressing plate can return to its original position even without relying on the return force of the return key. In this way, the maximum stroke distance of the return key can be reduced, thereby reducing the number of spring members used in the return key / switch function module, and the reliability of the switch is improved.

[0006] In the switch of the optional technical solution of the present utility model, the elastic member is a rib, the rib has a fixed end and a free end, the fixed end is connected to one of the frame and the pressing plate member, and the free end abuts against the other of the frame and the pressing plate member.

[0007] According to the above preferred technical solution, using a rib as the elastic member not only has a simple structure and is easy to manufacture, but also since the elastic force of the rib basically does not weaken with the increase of the use time, it can effectively apply a sufficient force to the pressing plate member for a long time to maintain the flat state of the pressing plate member.

[0008] In the switch of the optional technical solution of the present utility model, the rib is coiled in a plane perpendicular to the first direction.

[0009] According to the above preferred technical solution, the coiled rib can provide a more stable elastic force. And for the coiled rib, the force on itself is more uniform and it is less likely to be damaged and broken.

[0010] In the switch of the optional technical solution of the present utility model, the free end has an abutting portion protruding in the first direction.

[0011] According to the above preferred technical solution, since the free end has a protruding abutting portion, the reliability of the abutting between the free end and the pressing plate member / frame can be improved. At the same time, the weight reduction of the rib itself is taken into account to ensure that the rib has good elastic force.

[0012] In the switch of the optional technical solution of the present utility model, the frame has a boss, the inside of the boss is hollow and has an opening on the surface close to the pressing plate member, and the rib is arranged corresponding to the opening and the fixed end is connected to the edge of the opening.

[0013] According to the above preferred technical solution, since the rib is connected to the edge of the opening on the upper surface of the hollow boss, the rib can obtain appropriate movement space in the first direction, and the force received by the rib can be better absorbed, so that the rib is not easily damaged.

[0014] In the switch of the optional technical solution of the present utility model, the frame has a limiting portion, and the limiting portion limits the maximum stroke of the pressing plate member moving or rotating away from the return key.

[0015] According to the above preferred technical solution, by setting the limiting portion, the pressing plate member can be prevented from protruding outward under the action of the elastic member, so as to maintain the flat state of the pressing plate member. And after setting the limiting portion, the upper limit restriction on the elastic force provided by the elastic member can be reduced, which is beneficial to reducing the design and manufacturing cost of the elastic member.

[0016] In the switch of the optional technical solution of the present utility model, the limiting portion is a bayonet, and a buckle matching the bayonet is arranged on the side of the pressing plate member facing the frame.

[0017] According to the above preferred technical solutions, through the bayonet and the buckle, it is possible to improve the overall appearance of the back side of the pressing plate member facing the frame while limiting the maximum stroke of the pressing plate member moving or rotating away from the return key. Moreover, the bayonet and buckle structure is also convenient for installation and beneficial to the assembly efficiency.

[0018] In the switch of the alternative technical solution of the present utility model, the frame includes a decorative plate portion and an installation portion arranged side by side, and the pressing plate member is hinged to the first side portion of the installation portion away from the decorative plate portion.

[0019] According to the above preferred technical solutions, the pressing plate member is hinged to the first side portion and can rotate. By providing the decorative plate portion, the gap between the rotating side of the pressing plate member and the installation portion can be blocked, which is beneficial to improving the overall appearance of the switch product.

[0020] In the switch of the alternative technical solution of the present utility model, the installation portion has a recessed portion, the recessed portion is adjacent to the decorative plate portion, and the hollow portion is located in the recessed portion. The switch further includes a transmission plate member, the transmission plate member abuts against the pressing plate member and the return key, and the transmission plate member is hinged to the second side portion of the installation portion close to the decorative plate portion and is located in the recessed portion.

[0021] According to the above preferred technical solutions, by providing the transmission plate member, it is possible to reduce the rotation stroke of the pressing plate member while ensuring the operation feel and feedback. By providing the recessed portion, installation space can be provided for the transmission plate member without increasing the overall thickness of the frame. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] <Term>

[0032] "Up" means the direction close to the pressing plate member 2 in the first direction (refer to the z-axis direction in the accompanying drawings);

[0033] "Down" means the direction away from the pressing plate member 2 in the first direction (refer to the z-axis direction in the accompanying drawings).

[0034] Figure 1 The schematic diagram of the switch 100 provided in this embodiment in the assembled state is shown. As Figure 1 shown, the switch 100 includes a switch function module 2, a frame 1, and a pressing plate member 3. The frame 1, as a specific example, includes a decorative plate portion 12 and a mounting portion 13 arranged side by side. The pressing plate member 3 is mounted on the mounting portion 13, and the surface of the pressing plate member 3 is substantially flush with the surface of the decorative plate portion 12, thereby presenting a thin product appearance.

[0035] Although this embodiment describes the frame 1 by taking the frame 1 including the decorative plate portion 12 and the mounting portion 13 arranged side by side as an example, the present invention is not limited thereto. As long as it is a structure that can be connected to the switch function module 2 and the pressing plate member 3, it is within the technical scope of the frame 1 described in the present invention.

[0036] Figure 2 The exploded view of the switch 100 provided in this embodiment is shown. As Figure 2 shown, the switch 100 includes a switch function module 2, a frame 1, a pressing plate member 3, and a transmission plate member 5.

[0037] The upper part of the switch function module 2 is provided with a resilient key 20, and the resilient key 20 is configured to be movable between a pressing limit position and a resilient limit position in a first direction. The resilient key 20 refers to a key that, after being pressed, can automatically rebound and return to the resilient limit position under the action of a spring or other mechanical device inside the switch function module 2.

[0038] The frame 1 is installed above the switch function module 2. When the frame 1 is assembled with the switch function module 2, the resilient key 20 can protrude from the hollow portion 10 on the frame 1.

[0039] The pressing plate member 3 is arranged above the frame 1, that is, on the side of the frame 1 away from the switch function module 2. The pressing plate member 3 is coupled to the resilient key 20, that is to say, the force or movement of the pressing plate member 3 can be transmitted through a certain mechanism and affect the action of the resilient key 20. As a specific example, a transmission plate member 5 is arranged between the pressing plate member 3 and the resilient key 20 to transmit the force applied to the pressing plate member 3 to the resilient key 20. Specifically, the frame 1 includes a mounting portion 13, and the mounting portion 13 has a first side portion 131, a recessed portion 133, and a second side portion 132. The first side portion 131 is the side of the mounting portion 13 away from the decorative plate portion 12, and the pressing plate member 3 is hinged to the first side portion 131 so that the pressing plate member 3 can rotate about an axis. The recessed portion 133 that is concave downward in the direction of the resilient key 20 is arranged away from the first side portion 131, and the recessed portion 133 is adjacent to the decorative plate portion 12. The hollow portion 10 is located in the recessed portion 133, and the resilient key 20 passes through the hollow portion 10. The second side portion 132 is the side of the mounting portion 13 close to the decorative plate portion 12 and is located in the recessed portion 133, and the transmission plate member 5 is connected to the second side portion 132 so that the transmission plate member 5 can rotate about an axis. In other words, the first side portion 131 and the second side portion 132 are respectively arranged on both side portions of the mounting portion 13 and are offset in the first direction. Thus, when an external force is applied to the pressing plate member 3 to make it rotate, the transmission plate member 5 rotates and presses the resilient key 20.

[0040] Although this embodiment illustrates the coupling relationship between the pressing plate member 3 and the resilient key 20 by taking the transmission plate member 5 as an example, the present invention is not limited to this. As long as the structure can press the resilient key 20 by operating the pressing plate member 3, it is within the technical scope of "coupling" described in the present invention. In some embodiments, the pressing plate member 3 is in direct contact with the resilient key 20 without the aid of the transmission plate member 5. In some embodiments, the pressing plate member 3 presses the resilient key 20 by making a reciprocating motion in the first direction instead of by rotation to press the resilient key 20.

[0041] The elastic member 4, as a specific example, is disposed on the frame 1 and abuts against the pressing plate member 3. The elastic member 4 is configured to be deformable between a first limit position and a second limit position in a first direction, and when the return key 20 is located at the return limit position, the elastic member 4 is located between the first limit position and the second limit position. Specifically, when the pressing plate member 3 is pressed, the return key 20 moves towards the pressing limit position until the return key 20 reaches the pressing limit position. After the pressing plate member 3 is released, the return key 20 moves towards the return limit position until the return key 20 reaches the return limit position. When the return key 20 is located at the return limit position, there is almost no acting force between the pressing plate member 3 and the return key 20. However, since the elastic member 4 abuts against the pressing plate member 3, there is an acting force between the elastic member 4 and the pressing plate member 3, that is, the elastic member 4 applies an upward force to the pressing plate member 3, so that the pressing plate member 3 can be maintained at a specific position, that is, the pressing plate member 3 is in a flat state parallel to the wall where the mounting switch 100 is located. By providing the elastic member 4, the pressing plate member 3 can be maintained in a flat state without relying on the return key 20. This is beneficial to reducing the maximum stroke of the return key 20, thereby reducing the use of the spring member in the return key 20 / switch function module 2, and improving the reliability of the switch 100.

[0042] Although in this embodiment, it is disposed on the frame 1 and abuts against the pressing plate member 3, the present invention is not limited thereto. For example, in some embodiments, the elastic member 4 may be disposed on the pressing plate member 3 and abut against the frame 1.

[0043] Figure 3 The structural schematic diagram of the frame 1 of the switch 100 provided in this embodiment is shown. Figure 4 The structural schematic diagram of the pressing plate member 3 of the switch 100 provided in this embodiment is shown. Refer to Figure 3 and Figure 4 , the frame 1 has a limiting portion 11. As a specific example, the limiting portion 11 is a pair of bayonets 11 located on the peripheral wall of the recessed portion 133. A pair of buckles 31 matching the bayonets 11 are provided on the side of the pressing plate member 3 facing the frame 1. Figure 5 The sectional view of the switch 100 along the zoy plane in Figure 1 is shown, and the state when the buckle 31 cooperates with the bayonet 11 is shown, that is, the buckle 31 extends into the bayonet 11, and the upper surface of the buckle 31 abuts against the upper edge of the bayonet 11. By providing the bayonets 11 in the recessed portion 133 and the buckles 31 on the lower side surface of the pressing plate member 3, in this way, the bayonets 11 and the buckles 31 are hidden inside the switch 100, without affecting the appearance of the product in the assembled state. Although in this embodiment, a pair of bayonets 11 and a pair of buckles 31 are provided, the present invention is not limited thereto. In some embodiments, only one bayonet 11 and one buckle 31 are provided.

[0044] The bayonet 11 defines the maximum stroke for the pressing plate member 3 to move or rotate away from the rebound key 20. Specifically, when the rebound key 20 is at the rebound limit position, the elastic member 4 exerts an upward force on the pressing plate member 3, and the pressing plate member 3 may move upward and abut against the bayonet 11 accordingly. At this time, the bayonet 11 will exert a downward force on the pressing plate member 3, so that the pressing plate member 3 can be held in a specific position.

[0045] Although the bayonet 11 on the frame 1 is taken as an example to illustrate the limiting portion 11 in this embodiment, the present invention is not limited thereto. For example, in some embodiments, the limiting portion 11 may be a lug on the edge of the frame 1, and the lug presses on the upper surface of the pressing plate member 3.

[0046] Figure 6 The structural schematic diagram of the elastic member 4 of the switch 100 provided in this embodiment is shown. As Figure 6 shown, the elastic member 4 is a rib 4 coiled in a plane perpendicular to the first direction. The rib 4 has a fixed end 41 and a free end 42. The fixed end 41 is connected to the frame 1, and the free end 42 has an abutting portion 421 protruding in the first direction. The abutting portion 421 of the free end 42 abuts against the pressing plate member 3.

[0047] Specifically, the rib 4 is coiled into a U shape. Since the coiled rib 4 is more uniformly stressed itself, it can provide more stable elastic force. Of course, the coiled rib 4 can also be formed into various shapes such as a wave shape, a snake shape, a mosquito coil shape, etc., without particular limitation. There is a boss 134 in the recess 133 of the frame 1. The inside of the boss 134 is hollow and the upper surface has an opening. The rib 4 is arranged facing the opening, and the fixed end 41 of the rib 4 is connected to the inner edge of the opening. Since the rib 4 is connected to the inner edge of the opening on the upper surface of the hollow boss 134, the rib 4 can obtain appropriate movement space in the first direction, and the force received by the rib 4 can be better absorbed, so that the rib 4 is not easily damaged. Figure 4 The structural schematic diagram of the pressing plate member 3 of the switch 100 provided in this embodiment is shown. As Figure 4 shown, reinforcing ribs 32 are provided on the lower surface of the pressing plate member 3. Figure 7 Shown is Figure 1 The cross-sectional view of the switch 100 along the zox plane in Figure 7 shown, the abutting portion 421 of the free end 42 of the rib 4 abuts against the reinforcing rib 32 on the lower surface of the pressing plate member 3.

[0048] Refer to Figure 7, after pressing the pressing plate member 3, the transmission plate member 5 is stressed and presses down the return key 20. The return key 20 is pressed to the pressing limit position, and the elastic member 4 is also stressed and moves towards the first limit position. After releasing the pressing plate member 3, the return key 20 rebounds to the rebound limit position and drives the pressing plate member 3 to move upward, but it is not ensured that the pressing plate member 3 can return to its original position and maintain a flat state. During this process, the elastic member 4 moves towards the second limit position and remains stationary between the first limit position and the second limit position, maintaining a contact relationship with the pressing plate member 3. That is to say, the setting of the elastic member 4 can ensure that the pressing plate member 3 returns to its original position and maintains a flat state. It should be noted here that since the switch 100 is generally installed on a vertical wall. When the switch 100 is installed on a vertical wall, the direction of gravity is perpendicular to the first direction. Therefore, the elastic member 4 only needs to provide a relatively small force to maintain a contact relationship with the pressing plate member 3, thereby ensuring that the pressing plate member 3 returns to its original position and maintains a flat state.

[0049] Although the elastic member 4 is described by taking the rib 4 as an example in this embodiment, the present invention is not limited thereto. For example, in some embodiments, the elastic member 4 can also be a spring or a spring sheet.

[0050] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
