Description

Technical Field

[0001] This utility model relates to the field of switch technology, specifically to a reset switch. Background Technology

[0002] In electronic devices and electrical systems, reset switches are critical components used to restore devices to their initial state in the event of system malfunction or when a restart is required. Traditional reset switch designs generally rely on spring mechanisms to achieve the lateral reset function of the switch.

[0003] However, traditional spring-reset switches are often complex in design and require relatively large spaces. Secondly, when the spring is subjected to incorrect force, lateral forces may be generated, which not only accelerates spring wear but may also prevent the switch from resetting accurately. Furthermore, long-term friction between the spring and other internal components of the switch can cause wear on the surface of these components, and the spring is prone to plastic deformation under prolonged stress. This deformation is irreversible, gradually accumulating and causing the spring to lose its original elasticity, thus rendering the switch's reset function ineffective. Utility Model Content

[0004] The purpose of this utility model is to provide a reset switch. By improving the structure of the reset switch, at least one of the following technical effects is achieved: simplifying the reset switch, reducing the size of the reset switch, and ensuring the accurate reset of the reset switch.

[0005] To achieve the above objectives, this utility model provides a reset switch, which includes a driving assembly, a toggle member, a trigger member, and a cover. The toggle member is hinged to the cover via a toggle shaft and can move down with the cover to abut against the trigger member and drive the trigger member to rotate. The driving assembly includes two magnetic suction members, one of which is fixed to the cover and the other is fixed to the toggle member. The two magnetic suction members have opposite magnetic poles facing each other and are spaced apart in a first direction. Under the action of magnetic force, the two magnetic suction members can be aligned along a reference line, which extends along the first direction and passes through the axis of the toggle shaft.

[0006] This application uses a magnetic component to drive the toggle to rotate and reset, which replaces the traditional spring reset method. This greatly simplifies the structure of the reset switch and further reduces its size. The toggle is driven to reset by the attraction of two magnetic components, making the reset switch more accurate and less prone to failure, resulting in a better user experience.

[0007] Optionally, both magnetic components are cylindrical in shape.

[0008] The use of a cylindrical magnetic chuck makes it easier to align the magnetic chuck.

[0009] Optionally, the size of the magnetic attractor located on the faceplate is larger than the size of the magnetic attractor provided on the actuating member. Therefore, while miniaturizing the size of the magnetic attractor provided on the actuating member, the size of the magnetic attractor provided on the faceplate is increased, thereby amplifying the attraction force of both magnetic attractors, increasing the return stability of the actuating member, and increasing the return speed of the actuating member.

[0010] Optionally, it also includes a base and a trigger shaft fixed to the base, the trigger shaft being hinged to the trigger element; the trigger shaft and the actuation shaft extend in the same direction, and the reference line extends along a first direction and passes through the axis of the trigger shaft. This increases the compatibility stability of the actuation element and the trigger element.

[0011] Optionally, a return spring is also included, one end of which abuts against the cover and the other end against the base, and the return spring is arranged along the first direction. Thus, the cover can be driven to return the actuating element to its original position in the first direction.

[0012] Optionally, the actuating element has a trigger segment adapted to the trigger element, the trigger segment having two levers symmetrically arranged relative to the reference line. This ensures the accuracy of the adaptation between the actuating element and the trigger element, as well as the accuracy of the actuating element's return position.

[0013] Optionally, a weight-reduction channel is also provided between the two levers, the channel extending axially through the actuating member. This reduces the weight of the actuating member, lessening the load required for the magnetic component to drive the actuating member back to its original position.

[0014] Optionally, the connecting section is provided with a receiving cavity, the receiving cavity having a socket, and the magnetic element is inserted into the receiving cavity through the socket. This allows one magnetic element to be fixed at a set position on the toggle lever, ensuring the toggle lever can rotate, and also ensuring that one magnetic element can deflect relative to another magnetic element.

[0015] Optionally, the actuating element is provided with a connecting section located on the side of the triggering segment away from the triggering element; the magnetic element is bonded or welded to the end of the connecting section of the actuating element. Thus, one magnetic element can be fixed to a set position of the actuating lever, ensuring that the actuating lever can rotate, and also ensuring that one magnetic element can deflect relative to another magnetic element.

[0016] Optionally, the actuating element also has a shaft hole through which the actuating shaft passes; in the first direction, the shaft hole is located between the trigger section and the connecting section. Positioning the shaft hole between the trigger section and the connecting section effectively reduces the space occupied by the actuating element.

Detailed Implementation

[0026] This utility model provides a reset switch. By improving the structure of the reset switch, at least one of the following technical effects is achieved: simplifying the reset switch, reducing the size of the reset switch, and ensuring accurate reset of the reset switch.

[0027] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.

[0029] Please refer to Figures 1 to 5 , Figure 1 This is a schematic diagram of the reset switch in an embodiment of this utility model; Figure 2 yes Figure 1 A partial structural diagram, with the faceplate in its original position at this time; Figure 3 yes Figure 1 A partial structural diagram, showing the faceplate in the transition position at this time; Figure 4 yes Figure 1 A partial structural diagram, showing the faceplate in the trigger position at this time; Figure 5 This is a structural diagram of the toggle element and toggle shaft in their assembled state.

[0030] This invention provides a reset switch, which includes a drive assembly 100, a toggle member 200, a trigger member 300, and a cover 400. The cover 400, as the operating end, can move downwards in a first direction under the action of an external force; the first direction is the up-down direction shown in the figure. The toggle member 200 is hinged to the cover 400 via a toggle shaft 205 and can move downwards with the cover 400 until it abuts against the trigger member 300. That is, in the first direction, the trigger member 300 is located below the toggle member 200, i.e., on the side of the toggle member 200 away from the cover 400.

[0031] The reset switch also includes a base 500 and a trigger shaft fixed to the base 500. The trigger shaft is hinged to the trigger element 300, which is rotatable around the trigger shaft. The trigger shaft and the toggle shaft 205 extend in the same direction, and the surfaces containing the central axes of the trigger shaft and the toggle shaft 205 are perpendicular to the surface containing the first direction, that is, their central axes extend in a direction perpendicular to the plane of the paper.

[0032] In the technical solution of this application, the downward movement of the toggle member 200 can abut against the trigger member 300 and drive the trigger member 300. During the process of the trigger member 300 being in position, it can also drive the toggle member 200 to deflect around the toggle shaft 205 by a certain angle, thereby compensating for the amount of movement of the trigger shaft and the toggle shaft 205 towards each other in the first direction.

[0033] The trigger 300 can rotate relative to the first direction in a positive or negative direction under the action of the toggle 200 to switch to the open or closed position to realize the energized and de-energized state of the reset switch.

[0034] In this application, after the trigger 300 is pushed down into place by the actuating member 200, the actuating member 200 moves upward in the opposite direction to move away from the trigger 300. At this time, the actuating member 200, which has deflected at a certain angle, needs to be reversed back to its original position so that it can be matched with the trigger 300 again in the next operation. In order to achieve the return of the actuating member 200, this application provides a driving assembly 100, which includes two magnetic suction members 101. One magnetic suction member 101 is fixed to the cover 400, and the other magnetic suction member 101 is fixed to the actuating member 200. The magnetic suction member 101 and the corresponding cover 400 or actuating member 200 can be fixedly connected by means of gluing, welding, riveting or snap-fitting, as long as a fixed connection between the two can be achieved.

[0035] The two magnetic attractors 101 are arranged with opposite magnetic poles facing each other and spaced apart in the first direction. Specifically, each magnetic attractor 101 has a positive magnetic pole and a negative magnetic pole arranged along the first direction. The two magnetic attractors 101 are distributed vertically along the first direction, and the opposite magnetic poles of the two magnetic attractors face each other, that is, the positive magnetic pole and the negative magnetic pole are arranged opposite each other, so that the two magnetic attractors are in an attractive state. The opposite arrangement means that there is a spacer 102 between the two magnetic attractors. The spacer 102 allows the magnetic attractor 101 located on the actuating member 200 to deflect a certain angle relative to the cover 400 when the actuating member 200 deflects a certain angle, thereby avoiding interference with the deflection of the actuating member 200.

[0036] In this embodiment, the two magnetic attractors 101 can be aligned along a reference line s1 under the action of magnetic force. The reference line s1 extends along a first direction and passes through the central axis of the actuating shaft 205. The central axis of the actuating shaft 205 is the center of the radial section of the actuating shaft 205, that is, the first reference phase passes through the center of the radial section of the actuating shaft 205.

[0037] Specifically, a magnetic field exists around a magnetic component. When the opposite sides of two magnetic components approach each other, their magnetic fields interact. Under the influence of the magnetic field, the magnetic component tends to achieve a balance between its own magnetic field and the surrounding magnetic field. This balance often manifests as the magnetic components attracting each other and tending to align in the center. This alignment refers to alignment along the reference line s1, thereby achieving a more stable attraction state and ultimately exhibiting a centered and leveled attraction phenomenon.

[0038] In the technical solution of this application, the magnetic component can be a cylinder, or it can be a square, rectangular, rhomboid, or other irregular structure. The reference line s1 extends along the first direction and passes through the center of the magnetic component. This center can be the geometric center of the magnetic component or the magnetic force center of the magnetic component.

[0039] This application uses a magnetic component to drive the toggle 200 to rotate and reset, which replaces the traditional spring reset method. This greatly simplifies the structure of the reset switch and further reduces its size. The toggle 200 is driven to reset by the attraction of two magnetic components 101, making the reset switch reset more accurate and less prone to failure, resulting in a better user experience.

[0040] In this application, both magnetic attractors 101 are cylindrical structures. Using cylindrical magnetic attractors 101 makes them easier to align.

[0041] In the example shown, the size of the magnetic 101 located on the faceplate 400 is larger than the size of the magnetic 101 located on the actuating member 200. That is, when projecting the two magnetic 101s in the first direction, the projection range of the magnetic 101 on the faceplate 400 covers the projection range of the magnetic 101 on the actuating member 200. Therefore, while miniaturizing the size of the magnetic 101 on the actuating member 200, the size of the magnetic 101 on the faceplate 400 is increased, thereby amplifying the attraction force of both magnetic 101s, increasing the return stability and return speed of the actuating member 200.

[0042] In some specific embodiments, the actuating member 200 has a triggering section 201 adapted to the triggering member 300. The triggering section 201 has two levers 201a, the head ends of which converge to one end, and the tail ends of which extend radially away from each other along the actuating shaft 205. The levers 201a are adapted to the triggering member 300. The two levers 201a are symmetrically arranged with respect to the reference line s1. This ensures the accuracy of the adaptation between the actuating member 200 and the triggering member 300, and also ensures the accuracy of the return position of the actuating member 200.

[0043] Specifically, the trigger 300, in order to adapt to the lever 201a, is provided with two stepped structures 301. These two stepped structures 301 can adapt to the corresponding lever 201a, and are located at the top of the trigger 300. Each stepped structure 301 has a generally radially extending stepped surface 301a, which is lower than the top surface 301b of the trigger 300. The stepped structure 301 also includes an inner wall 302, which extends vertically and connects the top surface 301b and the stepped surface 301a of the trigger 300. The lever 201a adapts to the stepped surface 301a and the inner wall 302 to drive the trigger 300; the specific driving process will be described in detail later.

[0044] In the example shown, a weight-reducing channel 202 is also provided between the two levers 201a, and the weight-reducing channel 202 passes through the actuating member 200 axially. This reduces the weight of the actuating member 200, lessening the load required for the magnetic component to drive the actuating member 200 back to its original position. Reference line s1 passes through the center of the weight-reducing channel 202, thereby ensuring that the weight of the two levers 201a is approximately equal.

[0045] In one specific embodiment, the actuating member 200 further includes a connecting section 203 to accommodate the magnetic attractor 101. The connecting section 203 is located on the side of the trigger section 201 away from the trigger member 300. The connecting section 203 is provided with a receiving cavity 203a, which has a socket 203-1. The magnetic attractor 101 is inserted into the receiving cavity 203a through the socket 203-1. This allows one magnetic component to be fixed at a set position on the actuating lever, ensuring that the actuating lever can rotate and that one magnetic component can deflect relative to another.

[0046] Alternatively, the magnetic element 101 can be bonded or welded to the end of the connecting section 203 of the actuating element 200. This allows one magnetic element to be fixed at a set position on the actuating lever, ensuring the lever can rotate and that one magnetic element can deflect relative to another.

[0047] To accommodate the actuating shaft 205, the actuating member 200 is also provided with a shaft hole 204 through which the actuating shaft 205 passes; in the first direction, the shaft hole 204 is located between the trigger section 201 and the connecting section 203. Positioning the shaft hole 204 between the trigger section 201 and the connecting section 203 effectively reduces the space occupied by the actuating member 200.

[0048] In an alternative embodiment, to improve the fitting stability and accuracy of the toggle member 200 and the trigger member 300, the reference line s1 extends along a first direction and passes through the central axis of the trigger shaft. The central axis of the trigger shaft extends axially and passes through the radial cross-section center of the trigger shaft, and the reference line s1 passes through the radial cross-section center of the trigger shaft.

[0049] In the technical solution of this application, in order to drive the face cover 400 to reset along the first direction, the reset switch further includes a reset spring 600. One end of the reset spring 600 abuts against the face cover 400, and the other end abuts against the base 500. The reset spring 600 is arranged along the first direction. Thus, the face cover 400 can be driven to return the toggle member 200 to its original position in the first direction.

[0050] The specific working process of the return spring 600 of this application is as follows. For ease of description, the cover 400 is defined to have a home position, a transition position, and a trigger position in the first direction from top to bottom. The position where the actuating member 200 and the trigger member 300 first abut are defined as the transition position of the cover 400. In the first direction, the transition position is located between the home position and the trigger position.

[0051] Process 1:

[0052] In the scheme of this application, an external force is applied to drive the cover 400 to move downward from its original position. During the process of the cover 400 moving from its original position to the transition position, the actuating member 200 is driven to move downward synchronously via the actuating shaft 205 until the actuating member 200's lever 201a abuts against the trigger member 300 in the first direction. At this time, the trigger member 300 is in the open or closed position. Here, the open and closed positions refer to the trigger member 300 deflecting at a certain angle relative to the first direction along different directions.

[0053] Specifically, when the trigger 300 is in the open or closed position, because the trigger 300 is tilted at a certain angle, one step surface 301a is higher than the other step surface 301a. At this time, the lever 201a abuts against the higher step surface 301a, thereby driving the trigger 300 to rotate through the step structure 301 until the trigger 300 rotates to the point where the step surface 301a is lower than the other step surface 301a.

[0054] In this process, the tail end of the lever 201a first abuts against the upper stepped surface 301a, thereby starting to drive the trigger 300 to rotate.

[0055] Process Two:

[0056] In order to switch the trigger 300 to another position, that is, from the open position to the closed position or from the closed position to the open position, the cover 400 is further pressed down to press the cover 400 from the transition position to the trigger position.

[0057] As the cover 400 is pressed down further, the actuating member 200 gradually drives the trigger member 300 to rotate from the original open or closed position to another position.

[0058] During this process, as the tail end of the lever 201a moves downward synchronously, it rotates along with the trigger 300 until it abuts against the inner wall 302 and the stepped surface 301a. As the cover 400 moves further downward, the lever 201a drives the trigger 300 into position.

[0059] Process 3:

[0060] After the trigger 300 is pushed into place, the external force on the cover 400 disappears, and under the action of the return spring 600, it can spring back from the trigger position to its original position along the first direction. At this time, the toggle 200 moves in the first direction away from the trigger 300. After separating from the trigger 300, the toggle 200 rotates back to its original position under the action of the magnetic attraction assembly.

[0061] Compared with the prior art, the technical solution of this application has the following advantages:

[0062] First, this application uses a magnetic component to drive the toggle 200 to rotate and reset, which replaces the traditional spring reset method. This greatly simplifies the structure of the reset switch and further reduces its size. The toggle 200 is driven to reset by the attraction of two magnetic components 101, making the reset switch reset more accurate and less prone to failure, resulting in a better user experience.

[0063] Secondly, the original radial return spring was eliminated, avoiding the risk of functional failure caused by the easy plastic deformation of the radial spring.

[0064] Third, the reset method between the faceplate 400 and the toggle 200 is a non-contact drive reset, which will not cause failure due to friction.

[0065] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
