Abstract
Description
Technical Field
[0001] This application belongs to the technical field of automotive buttons, and particularly relates to an automatically reset automotive button switch. Background Art
[0002] With the continuous improvement of people's living standards, people's requirements for various aspects of automobiles are also getting higher and higher. There are many button switches installed in the interior of existing automobiles to control the cutting off or connecting of circuits. Generally, the cooperation of an elastomer and a plastic housing is used to achieve pressing and rebounding, including a button cap, a static contact, and a moving contact. By pressing the button cap, the moving contact is driven to contact the static contact, making the circuit in a connected state, which is convenient for controlling the electrical components in the automobile interior.
[0003] For example, the patent with the publication number CN209785808U discloses a button switch for the interior of an automobile. A limit sleeve is provided between the button cap and the inner wall of the control cavity. One end of the limit sleeve abuts against a limit ring and is provided with a locking block. A locking groove is provided on the outer wall of the pressing column end. The locking groove includes a transverse groove arranged along the circumference of the pressing column end and a longitudinal groove arranged along the longitudinal direction of the pressing column end. The transverse groove and the longitudinal groove are arranged in an L shape, and the longitudinal groove extends to the convex edge end. The locking block is slidably fitted in the locking groove. The other end of the limit sleeve extends outside the control cavity and is provided with a dial, and the dial is attached to the convex edge end.
[0004] The above patent enables the switch to have the function of preventing accidental operation and opening by means of a limit sleeve. Although the effect of locking the switch can be achieved, it is achieved by the switching of the locking block, resulting in more cumbersome operation when opening the switch. Once forgetting to lock, it will also cause accidental touch. Therefore, improvements are needed. Summary of the Utility Model
[0005] The purpose of this application is to provide an automatically reset automotive button switch that can solve the above problems.
[0006] The purpose of this application is to provide an automatically reset automotive button switch, including:
[0007] A housing with a chamber provided inside;
[0008] A pressing member provided in the housing and capable of sliding in the chamber;
[0009] A locking assembly, including a reset assembly provided at the bottom of the pressing member for providing reset, a contact post provided at the bottom of the reset assembly, a moving contact piece provided at the bottom of the contact post, and a static contact piece provided at the bottom of the chamber;
[0010] A contact assembly, including a static contact member provided at the bottom of the chamber and a moving contact member provided at the bottom of the pressing member;
[0011] Among them, the switch is turned on after the static contact and the dynamic contact come into contact.
[0012] Adopting the above-mentioned self-resetting automotive push-button switch, an internal chamber is provided inside the housing to accommodate and protect the internal structure of the switch. The pressing member is arranged inside the housing and can slide in the chamber along a preset direction. The user operates the switch by pressing the pressing member. The locking assembly is integrated inside or at the bottom of the pressing member. Among them, the reset assembly is used to automatically reset the pressing member to its initial position after it is released, ensuring that the switch is in the off state when not activated. The contact post is arranged below the reset assembly and moves with the pressing member. The moving contact piece is arranged at the bottom of the contact post, and the static contact piece is arranged at the bottom of the chamber and cooperates with the moving contact piece. Only when the two come into contact can the contact assembly be in contact and energized. The contact assembly includes a static contact and a dynamic contact. The dynamic contact is arranged at the bottom of the pressing member and forms a second contact point with the static contact, which is used to realize additional switch state confirmation or anti-misoperation function.
[0013] In the non-pressed state, the pressing member is at a high position, the moving contact piece is separated from the static contact piece, and the contact assembly is in the off state. When the user presses the pressing member, the contact post drives the moving contact piece to move downward until the moving contact piece contacts the static contact piece. At this time, the contact assembly is turned on. Then, when pressing downward further, after the static contact and the dynamic contact come into contact, the switch is turned on and energized. If the switch needs to be turned off, the user releases the pressing member, and the reset assembly automatically resets the pressing member and the contact post. The static contact and the dynamic contact are separated, and the circuit is disconnected. Through this design, the opening of the switch requires a clear pressing action, and the self-resetting function avoids the problem of misoperation caused by forgetting to lock, improving the safety and convenience of use.
[0014] Furthermore, the reset assembly includes:
[0015] A guiding frame, arranged at the bottom of the pressing member, and a through hole for the contact post to pass through is arranged at its bottom;
[0016] A movable plate, arranged inside the guiding frame;
[0017] A spring assembly, including a first spring and a second spring arranged on both sides of the movable plate;
[0018] Among them, when the moving contact piece contacts the static contact piece, as the pressing member continues to be pressed downward, the first spring and the second spring are compressed. When the moving contact piece is separated from the static contact piece, as the pressing member rises, the first spring and the second spring are reset.
[0019] The guiding frame is arranged at the bottom of the pressing member and serves as a supporting structure for the movable plate and the spring assembly. A through hole for the contact post to pass through is provided at the bottom of the guiding frame to ensure that the contact post can smoothly move with the pressing member and contact or separate from the static contact piece. The movable plate is arranged within the guiding frame and is directly connected to the contact post. When the pressing member is pressed, the movable plate will move downward therewith. The spring assembly includes a first spring and a second spring arranged on both sides of the movable plate. These two springs are respectively located on two opposite sides of the movable plate to provide a uniform restoring force and enable the pressing member to continue to move downward after the movable contact piece contacts the static contact piece. When the movable contact piece contacts the static contact piece, if the user continues to press down the pressing member, the first spring and the second spring will be further compressed to store elastic potential energy. Once the user releases the pressing member, the first spring and the second spring will release the stored elastic potential energy to separate the movable contact piece from the static contact piece, thereby realizing the automatic reset of the switch.
[0020] In the initial state, the spring assembly is in a natural state, the pressing member and the contact post are at a high position, and the movable contact piece is separated from the static contact piece. When the user presses the pressing member, the contact post moves downward therewith until the movable contact piece contacts the static contact piece. If the user continues to press down the pressing member, the spring assembly is further compressed until the static contact member contacts the movable contact member and the switch is turned on. Once the user releases the pressing member, the restoring force of the spring assembly causes the movable plate, the contact post, and the pressing member to quickly return to the initial position, the static contact member is separated from the movable contact member, and the movable contact piece is separated from the static contact piece, and the circuit is disconnected. This not only ensures the automatic reset function of the switch but also improves the durability and operating feel of the switch through the buffering effect of the spring assembly.
[0021] Further: A third spring is arranged at the bottom of the pressing member. The third spring is arranged within the chamber, and its end away from the pressing member contacts the bottom of the chamber.
[0022] The third spring is arranged at the bottom of the pressing member and is located within the chamber. One end of it is connected to the bottom of the pressing member, and the other end contacts the bottom of the chamber, which can provide an upward restoring force for the pressing member. When the user presses down the pressing member, the pressing member slides downward against the restoring force of the third spring. At the same time, the contact post in the locking assembly moves downward therewith until the static contact member contacts the movable contact member and the circuit is turned on. Once the user releases the pressing member, the third spring immediately releases the stored elastic potential energy, pushing the pressing member to quickly move upward and the circuit is disconnected, and the switch returns to the off state.
[0023] Further, the static contact member includes a first support rod and a contact strip arranged on the support rod;
[0024] The movable contact member includes a second support rod and a contact point arranged on the second support rod;
[0025] Wherein, the switch is turned on after the contact point contacts the contact strip.
[0026] The first support rod is installed at the bottom of the chamber, and the contact strip is arranged on the first support rod for making contact with the contact point of the moving contact piece to establish an electrical connection. The second support rod moves along with the movement of the pressing member, and the contact point is arranged on the second support rod for making contact with the contact strip of the static contact piece to control the switch state. When the pressing member is not pressed, the contact point of the moving contact piece and the contact strip of the static contact piece are in a separated state, the circuit is disconnected, and the switch is in the closed state. When the user presses the pressing member downward, the moving contact piece moves downward until its contact point contacts the contact strip of the static contact piece. At this time, the circuit is conducted and the switch is turned on.
[0027] Further, a guiding slider is arranged on the side wall of the movable plate, and a guiding chute adapted to the guiding slider is arranged on the inner wall of the guiding frame. The movable plate slides up and down in the guiding frame along the guiding chute through the guiding slider.
[0028] The movable plate can move along with the movement of the pressing member and transmit pressure to the contact column and the spring assembly. The guiding slider is arranged on the side wall of the movable plate, and its shape and size match the guiding chute on the inner wall of the guiding frame. The function of the guiding slider is to provide a stable sliding track for the movable plate, prevent it from shifting or shaking during the movement, avoid the spring from jamming during the pressing and resetting processes, ensure that the movable plate can move smoothly and accurately without shifting or shaking, and help to maintain the accurate alignment between the contact column and the static contact piece, so as to ensure that the circuit can be reliably conducted when needed.
[0029] Further, a limiting protrusion extending downward is arranged at the bottom of the pressing member, and the limiting protrusion fits with the inside of the chamber.
[0030] The limiting protrusion can ensure that the pressing member maintains the correct position and trajectory when moving in the chamber. When the pressing member is pressed, the limiting protrusion slides along the inside of the chamber, preventing the pressing member from deviating from the predetermined moving direction. The fitting of the limiting protrusion with the inner wall of the chamber can also enhance the stability of the pressing member during the movement. By reducing the shaking and deviation, the limiting protrusion helps to ensure that the pressing member can accurately and reliably perform its switch function.
[0031] The beneficial effects of this application are as follows:
[0032] 1. By setting the locking component and the contact component, the opening of the switch requires a clear pressing action, and the automatic reset function avoids the problem of accidental touch caused by forgetting to lock, improving the safety and convenience of use.
[0033] 2. By setting the first spring and the second spring, the pressing member can be further compressed, enabling the moving contact piece to be separated from the static contact piece, thereby realizing the automatic reset of the switch. This not only ensures the automatic reset function of the switch but also improves the durability and operating feel of the switch through the buffering effect of the spring assembly;
[0034] 3. By using the guiding slider and guiding chute in cooperation, a stable sliding track is provided for the movable plate to prevent it from shifting or wobbling during movement, avoid the spring from jamming during pressing and resetting, ensure that the movable plate can move smoothly and precisely without shifting or wobbling, help maintain the accurate alignment between the contact post and the static contact piece, and thus ensure that the circuit can be reliably conducted when needed.

[0041] The following will, in conjunction with the accompanying drawings, explain in detail the automatic reset automotive key switch provided by the embodiments of the present application through specific embodiments and their application scenarios.
[0042] Embodiment 1:
[0043] As Figure 1 and Figure 2 shown, the embodiments of the present application provide an automatic reset automotive key switch, including:
[0044] A housing 100, which is internally provided with a chamber 110;
[0045] A pressing member 200, which is arranged in the housing 100 and can slide in the chamber 110;
[0046] A locking assembly 300, including a reset assembly 310 arranged at the bottom of the pressing member 200 and used for providing reset, a contact post 320 arranged at the bottom of the reset assembly 310, a moving contact piece 330 arranged at the bottom of the contact post 320, and a static contact piece 340 arranged at the bottom of the chamber 110;
[0047] A contact assembly 400, including a static contact member 410 arranged at the bottom of the chamber 110 and a moving contact member 420 arranged at the bottom of the pressing member 200;
[0048] Wherein, when the static contact member 410 and the moving contact member 420 are in contact, the switch is turned on.
[0049] In some embodiments of the embodiments of the present application, as Figure 1 shown, using the above-mentioned automatic reset automotive key switch, an internal chamber 110 is provided in the housing 100 to accommodate and protect the internal structure of the switch. The pressing member 200 is arranged in the housing 100 and can slide in the chamber 110 along a preset direction. The user operates the switch by pressing the pressing member 200. The locking assembly 300 is integrated inside or at the bottom of the pressing member 200. Among them, the reset assembly 310 is used to automatically reset the pressing member 200 to its initial position after it is released, ensuring that the switch is in the off state when not activated. The contact post 320 is arranged below the reset assembly 310 and moves with the pressing member 200. The moving contact piece 330 is arranged at the bottom of the contact post 320, and the static contact piece 340 is arranged at the bottom of the chamber 110 and cooperates with the moving contact piece 330. When the two are in contact, the contact assembly 400 can be in contact and energized. The contact assembly 400 includes a static contact member 410 and a moving contact member 420. The moving contact member 420 is arranged at the bottom of the pressing member 200 and forms a second contact point 422 with the static contact member 410, which is used to realize an additional switch state confirmation or anti-misoperation function.
[0050] In the non-pressed state, the pressing member 200 is in the high position, the moving contact piece 330 is separated from the static contact piece 340, and the contact assembly 400 is in the open state. When the user presses the pressing member 200, the contact post 320 drives the moving contact piece 330 to move downward until the moving contact piece 330 contacts the static contact piece 340. At this time, the contact assembly 400 is turned on. Then, when pressing downward further, after the static contact member 410 and the moving contact member 420 contact, the switch is powered on and turned on. If the switch needs to be turned off, the user releases the pressing member 200, and the reset assembly 310 automatically resets the pressing member 200 and the contact post 320. The static contact member 410 and the moving contact member 420 are separated, and the circuit is disconnected. Through this design, the opening of the switch requires a clear pressing action, and the automatic reset function avoids the problem of accidental touch caused by forgetting to lock, improving the safety and convenience of use.
[0051] Embodiment 2:
[0052] The embodiment of the present application provides an automatically reset automotive key switch. In addition to including the above technical features, the automatically reset automotive key switch of the embodiment of the present application further includes the following technical features.
[0053] As Figure 2 shown, the reset assembly 310 includes:
[0054] A guiding frame 311, disposed at the bottom of the pressing member 200, and a through hole 312 for the contact post 320 to pass through is provided at its bottom;
[0055] A movable plate 313, disposed within the guiding frame 311;
[0056] A spring assembly, including a first spring 314 and a second spring 315 disposed on both sides of the movable plate 313;
[0057] Wherein, after the moving contact piece 330 contacts the static contact piece 340, as the pressing member 200 continues to be pressed downward, the first spring 314 and the second spring 315 are compressed. After the moving contact piece 330 is separated from the static contact piece 340, as the pressing member 200 is lifted, the first spring 314 and the second spring 315 are reset.
[0058] In an embodiment of the present application, the guiding frame 311 is disposed at the bottom of the pressing member 200 and serves as a supporting structure for the movable plate 313 and the spring assembly. A through hole 312 for the contact post 320 to pass through is provided at the bottom thereof to ensure that the contact post 320 can smoothly move with the pressing member 200 and contact or separate from the static contact piece 340. The movable plate 313 is disposed within the guiding frame 311 and is directly connected to the contact post 320. When the pressing member 200 is pressed, the movable plate 313 will move downward therewith. The spring assembly includes a first spring 314 and a second spring 315 disposed on both sides of the movable plate 313. These two springs are respectively located on two opposite sides of the movable plate 313 to provide a uniform restoring force and enable the pressing member 200 to continue to move downward after the movable contact piece 330 contacts the static contact piece 340. When the movable contact piece 330 contacts the static contact piece 340, if the user continues to press down the pressing member 200, the first spring 314 and the second spring 315 will be further compressed to store elastic potential energy. Once the user releases the pressing member 200, the first spring 314 and the second spring 315 will release the stored elastic potential energy to separate the movable contact piece 330 from the static contact piece 340, thereby realizing the automatic reset of the switch.
[0059] In the initial state, the spring assembly is in a natural state. The pressing member 200 and the contact post 320 are at a high position, and the movable contact piece 330 is separated from the static contact piece 340. When the user presses the pressing member 200, the contact post 320 moves downward therewith until the movable contact piece 330 contacts the static contact piece 340. If the user continues to press down the pressing member 200, the spring assembly is further compressed until the static contact member 410 contacts the movable contact member 420 and the switch is turned on. Once the user releases the pressing member 200, the restoring force of the spring assembly causes the movable plate 313, the contact post 320, and the pressing member 200 to quickly return to the initial position, the static contact member 410 is separated from the movable contact member 420, and the movable contact piece 330 is separated from the static contact piece 340, and the circuit is disconnected, which not only ensures the automatic reset function of the switch but also improves the durability and operating feel of the switch through the buffering effect of the spring assembly.
[0060] Moreover, a third spring 210 is disposed at the bottom of the pressing member 200. The third spring 210 is disposed within the chamber 110, and one end thereof remote from the pressing member 200 contacts the bottom of the chamber 110.
[0061] In some embodiments of the present application, the third spring 210 is disposed at the bottom of the pressing member 200 and located within the chamber 110. One end thereof is connected to the bottom of the pressing member 200, and the other end contacts the bottom of the chamber 110, which can provide an upward restoring force for the pressing member 200. When the user presses the pressing member 200 downward, the pressing member 200 slides downward against the restoring force of the third spring 210. At the same time, the contact post 320 in the locking assembly 300 moves downward accordingly until the static contact member 410 contacts the moving contact member 420, and the circuit is turned on. Once the user releases the pressing member 200, the third spring 210 immediately releases the elastic potential energy it stores, pushing the pressing member 200 to move upward rapidly, the circuit is disconnected, and the switch returns to the off state.

[0066] Among them, when the contact point 422 contacts the contact strip 412, the switch is turned on.
[0067] In the embodiment of the present application, the first support rod 411 is installed at the bottom of the chamber 110, and the contact strip 412 is disposed on the first support rod 411 for contacting the contact point 422 of the moving contact member 420 to establish a circuit connection. The second support rod 421 moves with the movement of the pressing member 200, and the contact point 422 is disposed on the second support rod 421 for contacting the contact strip 412 of the static contact member 410 to control the switch state. When the pressing member 200 is not pressed, the contact point 422 of the moving contact member 420 is in a separated state from the contact strip 412 of the static contact member 410, the circuit is disconnected, and the switch is in the off state. When the user presses the pressing member 200 downward, the moving contact member 420 moves downward accordingly until its contact point 422 contacts the contact strip 412 of the static contact member 410. At this time, the circuit is turned on and the switch is turned on.
