Description

Technical Field

[0001] The embodiments of the present application relate to the field of electrical equipment, and specifically to a switch. Background Art

[0002] As a control element for controlling the on / off of a circuit, a switch is an indispensable part of a circuit system. With the progress of technology and the improvement of people's requirements for product performance, there are more requirements for the structural stability, operation convenience, occupied space, etc. of the switch.

[0003] In existing switches, multiple buttons are usually set in one switch, and the multiple buttons respectively correspond to different current circuits, so that a user can control the on / off of multiple current circuits through the multiple buttons of one switch.

[0004] However, in current switches, the connection structure between the buttons and the current circuits is often relatively complex, and the volume and weight of the switch are large, making it impossible to achieve miniaturization. Therefore, how to make the structure of the switch simpler has become a technical problem to be solved. Utility Model Content

[0005] In view of the above problems, the embodiments of the present application provide a switch. In this switch, the button is connected to a transmission member, and the transmission member is connected to the moving contact piece of the conductive assembly, forming a simple two-stage transmission mechanism, which has a simple structure and high transmission efficiency.

[0006] In one aspect of the embodiments of the present application, a switch is provided. The switch includes a frame, a plurality of pressing assemblies, a limiting member, and a conductive assembly. The plurality of pressing assemblies are arranged side by side at intervals. Each pressing assembly includes a button and a transmission member. The button is connected to the transmission member, and the transmission member is installed on the frame, enabling the button and the transmission member to rotate coaxially and synchronously relative to the frame, and the rotation direction is perpendicular to the arrangement direction of the plurality of pressing assemblies. The limiting member includes a plurality of resisting portions. The plurality of resisting portions face the respective transmission members, and the relative direction between the resisting portion and the transmission member is the same as the arrangement direction of the plurality of pressing assemblies. The conductive assembly includes a plurality of movable moving contact pieces. The button is connected to the moving contact piece through the transmission member, enabling each moving contact piece to move synchronously with each button respectively to connect or disconnect the current circuit corresponding to each button.

[0007] In this switch, a simple two-stage transmission mechanism is formed among the button, the transmission member, and the conductive assembly, which has a simple structure and high transmission efficiency. Moreover, the resisting portion of the limiting member can limit the yaw amplitude of the pressing assembly in the arrangement direction of the plurality of pressing assemblies, ensure the uniformity of the gaps between the pressing assemblies, avoid interference between the pressing assemblies, and has high reliability.

[0008] In an optional manner, a pivot shaft is provided on the transmission member, and a pivot hole is provided on the frame. The pivot shaft and the pivot hole are docked, enabling the transmission member to be pivotally connected to the frame.

[0009] In this way, through the docking of the pivot shaft and the pivot hole, the transmission part is directly installed on the frame, with a compact structure, facilitating assembly and disassembly. Moreover, the docked pivot shaft and pivot hole rotate flexibly and have a strong load-bearing capacity.

[0010] In an alternative way, the limiting part includes a frame body fixedly connected to the frame. A pivot shaft is provided on the transmission part, and a pivot hole is provided on the frame body. The pivot shaft and the pivot hole are docked so that the transmission part is pivotally connected to the frame body.

[0011] In this way, the pivot hole is arranged on the frame body of the limiting part, which is more convenient for processing and is conducive to improving the position accuracy of the transmission part. The transmission part is installed on the frame body through the pivot shaft, facilitating assembly and disassembly. Moreover, the docked pivot shaft and pivot hole rotate flexibly and have a strong load-bearing capacity.

[0012] In an alternative way, a plurality of grooves are provided on the frame body, and the resisting part is a protruding structure arranged on the inner wall of the groove, and the transmission part is rotatably placed in the groove.

[0013] In this way, the frame body and the transmission part can be installed more compactly, which can further reduce the overall occupied space of the switch. Moreover, the resisting part is a protruding structure arranged on the inner wall of the groove, which is more convenient for processing and can better limit the movement track of each pressing component.

[0014] In an alternative way, the first end of the transmission part is located between a pair of opposing resisting parts, and the second end of the transmission part is located between another pair of opposing resisting parts. The first end and the second end of the transmission part are opposite ends that can rotate around the rotation axis.

[0015] In this way, by restricting the two ends of the transmission part through two pairs of resisting parts, the swinging amplitude of the transmission part can be restricted more precisely, making the gaps between the pressing components uniform enough to avoid interference between the pressing components and improving the reliability of the switch.

[0016] In an alternative way, a first clamping part is provided on the button, and a second clamping part is provided on the transmission part. The first clamping part and the second clamping part are clamped with each other so that the button and the transmission part can rotate synchronously.

[0017] In this way, the button and the transmission part are connected through the mutual clamping of the first clamping part and the second clamping part. The transmission part and the button can rotate synchronously and coaxially reliably. The button and the transmission part can be connected stably and reliably, and there are few overall components, facilitating installation and disassembly.

[0018] In an alternative way, the first clamping part is a clamping block, and the second clamping part is a clamping groove. A protruding embedding part is provided on the clamping block, and a concave embedding space is provided on the groove wall of the clamping groove. The embedding part is embedded in the embedding space, and the embedding direction of the embedding part is perpendicular to the direction in which the clamping block is inserted into the clamping groove.

[0019] In this way, the clamping block and the protruding embedding part form a clamping hook. The embedding part is embedded in the embedding space, and the embedding direction of the embedding part is perpendicular to the direction in which the clamping block is inserted into the clamping groove, which can strengthen the clamping effect between the clamping block and the clamping groove and make the connection between the button and the transmission part more firm.

[0020] In an optional way, the first clamping part is a clamping block, the second clamping part is a clamping groove, and the clamping block and the clamping groove are in interference fit.

[0021] In this way, the structures of the clamping block and the clamping groove are simple and convenient to process. When the two are butted, only the clamping block needs to be aligned with the clamping groove and pressed tightly, which is convenient for installation.

[0022] In an optional way, two pairs of the first clamping part and the second clamping part are arranged on the same pressing component, and the two pairs of the first clamping part and the second clamping part are respectively arranged at the two pressing ends of the pressing component.

[0023] In this way, a pair of the first clamping part and the second clamping part are arranged at each of the two pressing ends of the pressing component, which can make the connection between the button and the transmission part more reliable and ensure the transmission effect when the transmission part transmits the button action.

[0024] In the switch provided by the embodiment of the present application, the button is connected to the transmission part, the transmission part is connected to the moving contact piece of the conductive component, and the transmission part can directly synchronize the action of the button to the conductive component to control the on-off of the current loop. A simple two-stage transmission mechanism is formed among the button, the transmission part and the conductive component, with simple structure and high transmission efficiency. Moreover, the resisting part of the limiting part can limit the yaw amplitude of the pressing component in the arrangement direction of multiple pressing components, ensure the uniform gap between the pressing components, so that when the button is pressed, there will be no mutual interference between the pressing components, and each pressing component can respectively and reliably control the on-off of the current loop corresponding to each pressing component, with high reliability. The overall structure of the switch is simple, more compact, and has high reliability, which is beneficial to the miniaturization and integration of the switch.

For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0050] The switch provided by this application is as Figure 1 and Figure 2 shown, Figure 1 which is an exploded view of a switch provided by an embodiment of this application, Figure 2 and is a cross-sectional view of a switch involved in an embodiment of this application from a first perspective. Wherein, the switch includes a frame 10, a plurality of pressing components 20, a limiting member 30, and a conductive component 40.

[0051] The frame 10 is a frame structure that provides an installation space and support for the pressing component 20 and the conductive component 40. The frame 10 is used to connect to an installation base surface such as a wall surface to install the switch on the installation base surface. The frame 10 has a sufficient installation space reserved to accommodate at least part of the pressing component 20 and the conductive component 40. The installation space may specifically be a cavity structure, and auxiliary installation or positioning structures such as pillars may be provided in the cavity structure, which are not specifically limited herein.

[0052] The frame 10 has sufficient strength to support the pressing component 20 and the conductive component 40 with weight. At the same time, the strength of the frame 10 needs to ensure that the frame 10 can support the pressing operation received by the pressing component 20, that is, the frame 10 can withstand a certain pressing force without being damaged.

[0053] The pressing component 20 and the conductive component 40 are installed on the frame 10. The pressing component 20 is used to respond to the user's pressing operation and synchronize the pressing operation into the current loop formed by the conductive component 40, so that the current loop is turned on and off corresponding to the pressing operation.

[0054] There are multiple pressing components 20, and the multiple pressing components 20 are arranged side by side at intervals. The pressing component 20 specifically includes a key 21 and a transmission member 22. Its specific structure can be as Figure 1 、 Figure 3 and Figure 4 shown, Figure 3 is a schematic structural diagram of the transmission member of the switch involved in the embodiment of the present application, Figure 4 is a schematic structural diagram of the key of the switch involved in the embodiment of the present application.

[0055] The key 21 is a component for the user to press. The key 21 can be set as a long strip plate structure, or can be set as a protruding button structure, or can be set as a pressable oval structure, etc., which is not specifically limited here.

[0056] The key 21 is movably arranged on the frame 10 to move in response to the user's pressing operation. Specifically, the key 21 is connected to the transmission member 22, and the transmission member 22 is installed on the frame 10, so that the key 21 and the transmission member 22 can rotate coaxially and synchronously relative to the frame 10, and its rotation direction is perpendicular to the arrangement direction of the multiple pressing components 20.

[0057] The key 21 and the transmission member 22 are connected together, so that the key 21 and the transmission member 22 move synchronously, and the synchronous movement mode of the two is coaxial rotation. At the same time, the axial direction of the rotation axis is parallel to the arrangement direction of the multiple pressing components 20. The key 21 and the transmission member 22 are equivalent to forming two levers rotating around the rotation axis. When the two pressing ends of the key 21 are pressed, the two ends of the transmission member 22 also move synchronously. For example, when one end of the key 21 of a certain pressing component 20 is subjected to a pressing operation, the key 21 flips around the rotation axis, and the transmission member 22 rotates around the rotation axis in the same direction accordingly, and the key 21 and the transmission member 22 will not interfere with other pressing components when rotating.

[0058] There are many specific connection methods between the key 21 and the transmission member 22, such as connection by threaded connection, snap connection, etc.

[0059] Exemplarily, a feasible way is as Figure 2 andFigure 5 As shown Figure 5 Figure 5 This is a cross-sectional view of a switch involved in an embodiment of the present application from a second perspective. Among them, a first clamping portion 211 is provided on the button 21, and a second clamping portion 221 is provided on the transmission member 22. The first clamping portion 211 and the second clamping portion 221 are clamped with each other so that the button 21 and the transmission member 22 can rotate synchronously.

[0060] In this way, the button 21 and the transmission member 22 are connected by the mutual clamping of the first clamping portion 211 and the second clamping portion 221. The transmission member 22 and the button 21 can rotate synchronously and coaxially reliably. The button 21 and the transmission member 22 can be connected stably and reliably, and there are few overall components, which is convenient for installation and disassembly.

[0061] There are also many specific structural forms of the first clamping portion 211 and the second clamping portion 221, as long as it is ensured that the first clamping portion 211 and the second clamping portion 221 can be clamped with each other stably and reliably. For example, the first clamping portion 211 and the second clamping portion 221 can be specifically set as a clamping block, a clamping groove, a snap fastener, etc., which are not limited here.

[0062] In a specific embodiment, it can be as Figure 2 and Figure 5 As shown, the first clamping portion 211 is a clamping block, and the second clamping portion 221 is a clamping groove. A protruding embedding portion 212 is provided on the clamping block, and a concave embedding space 222 is provided on the groove wall of the clamping groove. The embedding portion 212 is embedded in the embedding space 222, and the embedding direction of the embedding portion 212 is perpendicular to the direction in which the clamping block is inserted into the clamping groove.

[0063] In this way, the clamping block and the protruding embedding portion 212 form a hook. The embedding portion 212 is embedded in the embedding space 222, and the embedding direction of the embedding portion 212 is perpendicular to the direction in which the clamping block is inserted into the clamping groove, which can strengthen the clamping effect between the clamping block and the clamping groove and make the connection between the button 21 and the transmission member 22 more firm.

[0064] In another specific embodiment, the first clamping portion 211 can be a clamping block, the second clamping portion 221 can be a clamping groove, and the clamping block and the clamping groove are press-fitted.

[0065] Among them, the interference fit is similar to the interference fit between a shaft and a hole. Specifically, the outer dimension of the clamping block is slightly larger than the dimension of the groove space of the clamping groove, so that after the clamping block is inserted into the clamping groove, the outer surface of the clamping block tightly abuts against the inner wall of the clamping groove, so that the clamping block is stuck in the clamping groove.

[0066] In this way, the structures of the clamping block and the clamping groove are simple and convenient to process. When the two are butted, only the clamping block needs to be aligned with the clamping groove and pressed tightly, which is convenient for installation.

[0067] In addition, in the same pressing assembly 20, the first engaging portion 211 and the second engaging portion 221 can be provided in multiple pairs. In a feasible manner, the first engaging portion 211 and the second engaging portion 221 are provided in two pairs on the same pressing assembly 20, and the two pairs of the first engaging portion 211 and the second engaging portion 221 are respectively arranged at the two pressing ends of the pressing assembly 20.

[0068] The two pressing ends of the pressing assembly 20 refer to the two ends of the pressing assembly 20 separated by the rotating shaft. When one of the two pressing ends is pressed down, the other end tilts up. The button 21 and the transmission member 22 are components that rotate synchronously and coaxially. The two pressing ends of the button 21 and the transmission member 22 correspond to each other, that is, the pressing ends on the same side of the button 21 and the transmission member 22 will be pressed down simultaneously.

[0069] In this way, a pair of the first engaging portion 211 and the second engaging portion 221 are respectively arranged at the two pressing ends of the pressing assembly 20, which can make the connection between the button 21 and the transmission member 22 more reliable and ensure the transmission effect when the transmission member 22 transmits the action of the button 21.

[0070] The transmission member 22 is also connected to the conductive assembly 40 at the same time to synchronize the action when the button 21 is pressed to the conductive assembly 40, so as to turn on or off the current loop in the conductive assembly 40 in response to the pressing operation received by the button 21.

[0071] The conductive assembly 40 is composed of multiple conductive members, and the conductive assembly 40 can be electrically connected to the incoming power wire and the outgoing power wire to form a current loop. The current loop corresponding to the pressing assembly 20 refers to the current loop whose on-off state can be controlled by the pressing assembly 20.

[0072] Such as Figure 1 and Figure 2 As shown, the conductive assembly 40 includes multiple movable moving contact pieces 41 and multiple fixedly arranged static contact pieces 42 and other conductive members. The moving contact pieces 41 and the static contact pieces 42 are arranged in pairs, and the moving contact pieces 41 and the static contact pieces 42 are arranged opposite to each other in terms of spatial position, so that each pair of the moving contact pieces 41 and the static contact pieces 42 respectively form the moving contact and the static contact of different current loops. When a pair of the moving contact pieces 41 and the static contact pieces 42 are in contact, the current loop corresponding to this pair of the moving contact pieces 41 and the static contact pieces 42 is turned on. When a pair of the moving contact pieces 41 and the static contact pieces 42 are separated, the current loop corresponding to this pair of the moving contact pieces 41 and the static contact pieces 42 is turned off.

[0073] The button 21 is connected to the moving contact piece 41 through the transmission member 22, so that each moving contact piece 41 can move synchronously with each button 21 to connect or disconnect the current circuit corresponding to each button 21. In other words, the transmission member 22 in each pressing assembly 20 is connected to a different moving contact piece 41, and each button 21 is connected to the moving contact piece 41 in the current circuit corresponding to each button 21, so that the movement of each moving contact piece 41 is controlled by each button 21. When a button 21 is pressed to the power-on state, the transmission member 22 then moves the moving contact piece 41 corresponding to the button 21 to a position in contact with the stationary contact piece 42, thereby connecting the current circuit corresponding to the button 21. When a button 21 is pressed to the power-off state, the transmission member 22 then moves the moving contact piece 41 corresponding to the button 21 to a position separated from the stationary contact piece 42, thereby disconnecting the current circuit corresponding to the button 21.

[0074] A simple two-stage transmission mechanism is formed between the button 21, the transmission member 22 and the conductive component 40, so that the transmission member 22 can directly synchronize the action of the button 21 to the conductive component 40 to control the on-off of the current circuit. There are fewer parts between the button 21 and the conductive component 40, the structure is simple, the transmission efficiency is high, the overall structure is more compact, and the assembly is more convenient, which can make the overall size of the switch smaller, which is conducive to the miniaturization and integration of the switch.

[0075] In this embodiment, the limiting member 30 is a structure for limiting the motion trajectory of the transmission member 22. Figure 1 and Figure 6 As shown, Figure 6 The schematic diagram of the structure of the switch involved in the embodiment of the present application when the button is hidden is shown in FIG. The limit member 30 includes a plurality of blocking portions 31 , and the plurality of blocking portions 31 are opposite to each transmission member 22 , and the relative direction between the blocking portions 31 and the transmission member 22 is consistent with the arrangement direction of the plurality of pressing components 20 .

[0076] The blocking portion 31 can block the transmission member 22 in the arrangement direction of the multiple pressing assemblies 20, so that the button 21 and the transmission member 22 can only rotate perpendicular to the arrangement direction of the multiple pressing assemblies 20. In this way, even if there is an installation gap when the button 21 and the transmission member 22 are installed on the frame 10, the swing amplitude of the button 21 and the transmission member 22 in the arrangement direction of the multiple pressing assemblies 20 is also limited by the blocking portion 31, so that there is always a relatively uniform gap between the pressing assemblies 20. When the button 21 is pressed, there will be no mutual interference between the pressing assemblies 20, and each pressing assembly 20 can reliably control the on and off of the current circuit corresponding to each pressing assembly 20, and the reliability of the switch is high.

[0077] In this embodiment, there are many ways to rotatably mount the transmission member 22 on the frame 10. Among them, the transmission member 22 can be directly connected to the frame 10 and mounted on the frame 10, or can be indirectly mounted on the frame 10 through components such as brackets and mounting seats.

[0078] When the transmission member 22 is directly connected to the frame 10, the transmission member 22 can be connected to the frame 10 by shaft-hole connection. Exemplarily, as Figure 2 shown, in an alternative way, a pivot shaft 51 is provided on the transmission member 22, and a pivot hole 52 is provided on the frame 10. The pivot shaft 51 and the pivot hole 52 are docked, so that the transmission member 22 is pivotally connected to the frame 10.

[0079] This way directly mounts the transmission member 22 on the frame 10 through the docking of the pivot shaft 51 and the pivot hole 52. Its structure is compact, facilitating assembly and disassembly. Moreover, the docked pivot shaft 51 and pivot hole 52 rotate flexibly and have a strong load-bearing capacity.

[0080] When the transmission member 22 and the frame 10 are indirectly mounted on the frame 10 through other components, an alternative way can be as Figure 1 and Figure 2 shown. The limiting member 30 includes a frame body 32, and the frame body 32 is fixedly connected to the frame 10. A pivot shaft 51 is provided on the transmission member 22, and a pivot hole 52 is provided on the frame body 32. The pivot shaft 51 and the pivot hole 52 are docked, so that the transmission member 22 is pivotally connected to the frame body 32.

[0081] The frame body 32 of the limiting member 30 acts as an intermediate structure between the transmission member 22 and the frame 10. The pivot shaft 51 and the pivot hole 52 of the transmission member 22 are docked, so that the transmission member 22 is rotatably mounted on the frame body 32, and the frame body 32 is fixedly connected to the frame 10, thereby enabling the transmission member 22 to perform fixed-axis rotation relative to the frame 10.

[0082] In this way, the pivot hole 52 is provided on the frame body 32 of the limiting member 30, which is more convenient for processing and is beneficial to improving the position accuracy of the transmission member 22. The transmission member 22 is mounted on the frame body 32 through the pivot shaft 51, facilitating assembly and disassembly. Moreover, the docked pivot shaft 51 and pivot hole 52 rotate flexibly and have a strong load-bearing capacity.

[0083] There are many setting ways for the structural forms of the above-mentioned pivot shaft 51 and pivot hole 52. Exemplarily, the pivot shaft 51 and the pivot hole 52 can be set as a round shaft and a round hole, or can be set as other special-shaped structures, such as setting the pivot shaft 51 and the pivot hole 52 as a shaft and a hole with a fan-shaped axial cross-section, etc.

[0084] An alternative way can be as Figure 6 and Figure 7 shown. Figure 7A partial schematic diagram of the position of the first end of the transmission member of the switch involved in the embodiment of the present application. Among them, a plurality of grooves 33 may be further provided on the frame body 32, the resisting portion 31 is a protruding structure provided on the inner wall of the groove 33, and the transmission member 22 is rotatably placed in the groove 33.

[0085] The number of the grooves 33 corresponds to the number of the transmission members 22, and the arrangement direction of the plurality of grooves 33 is the same as the arrangement direction of the plurality of pressing components 20, and the opening direction of the groove 33 also corresponds to the rotation direction of the transmission member 22. After the pivot shaft 51 and the pivot hole 52 of the transmission member 22 are docked, the transmission member 22 can be just located in the groove 33.

[0086] At the same time, the resisting portion 31 is a protruding structure provided on the inner wall of the groove 33, which just limits the movement amplitude of the transmission member 22 in the arrangement direction of the plurality of pressing components 20. Even if there is an assembly gap between the pivot shaft 51 and the pivot hole 52, the transmission member 22 will not swing excessively and cause interference between the pressing components 20. The resisting portion 31 can be specifically set as a rib structure of a U-shaped protrusion, or can be set as a boss, etc., which is not limited here.

[0087] In this way, the frame body 32 and the transmission member 22 can be installed more compactly, and the overall occupied space of the switch can be further reduced. Moreover, the resisting portion 31 is a protruding structure provided on the inner wall of the groove 33, which is more convenient for processing and can better limit the movement track of each pressing component 20.

[0088] In this embodiment, a plurality of resisting portions 31 can be provided for each transmission member 22. An optional way is as Figure 6 and Figure 7 shown. Among them, the first end of the transmission member 22 is located between a pair of opposing resisting portions 31, the second end of the transmission member 22 is located between another pair of opposing resisting portions 31, and the first end and the second end of the transmission member 22 are opposite ends that can rotate around the rotation axis.

[0089] Among them, the first end and the second end of the transmission member 22 are the pressing ends, that is, the first end and the second end of the transmission member 22 are equivalent to the two ends of a lever. When the first end of the transmission member 22 is pressed down with the movement of the button 21, the second end will tilt up.

[0090] The resisting portions 31 are provided in pairs, and a pair of resisting portions 31 are located on both sides of the first end of the transmission member 22, and another pair of resisting portions 31 are located on both sides of the second end of the transmission member 22, which can fully limit the yaw amplitude of the transmission member 22. The two pairs of resisting portions 31 can be as far away from the rotation axis of the transmission member 22 as possible to eliminate the amplification effect of the lever structure and reduce the swing amplitude of the two ends of the transmission member 22 in the arrangement direction of the plurality of pressing components 20.

[0091] In this way, the two ends of the transmission member 22 are restricted by two pairs of resisting portions 31, so that the swinging amplitude of the transmission member 22 can be restricted more precisely, the gaps between the pressing components 20 are made sufficiently uniform, interference between the pressing components 20 is avoided, and the reliability of the switch is improved.

[0092] In summary, in the switch described above, the button is connected to the transmission member, the transmission member is connected to the moving contact piece of the conductive component, and the transmission member can directly synchronize the movement of the button to the conductive component to control the on / off of the current loop. A simple two-stage transmission mechanism is formed among the button, the transmission member and the conductive component, with a simple structure and high transmission efficiency. Moreover, the resisting portion of the limiting member can restrict the yaw amplitude of the pressing component in the arrangement direction of multiple pressing components, ensure the uniformity of the gaps between the pressing components, so that when the button is pressed, there is no interference between the pressing components, and each pressing component can respectively and reliably control the on / off of the current loop corresponding to each pressing component, with high reliability. The overall structure of the switch is simple, more compact, and has high reliability, which is beneficial to the miniaturization and integration of the switch.
