Description

Technical Field

[0001] This invention relates to the field of low-voltage electrical technology, and more specifically, to a pressure device and switch. Background Technology

[0002] Among various switching devices in a power system, switches play a crucial role, and their performance directly affects the reliability and stability of power transmission. During the closing process of a switch, increasing the pressure on the moving contact ensures tight contact between the contacts in the closed state, greatly enhancing the stability of the contact connection and effectively reducing the contact resistance between the contacts.

[0003] However, most existing contact pressure application devices increase pressure throughout the entire closing and opening process of the contacts, resulting in poor operational flexibility. Although increasing contact pressure during the closing process has certain advantages, increasing contact pressure during the opening process can easily cause the moving contact to face greater separation resistance, slowing down the opening speed, prolonging the opening time, and thus shortening the service life of the switch and reducing operational safety. Summary of the Invention

[0004] The purpose of this invention is to provide a pressure device and switch that can flexibly adjust the contact pressure provided by the moving and stationary contacts under different contact states, thereby improving the contact life and safety.

[0012] Optionally, the rotating part includes a first connecting plate and a second connecting plate that are bent and connected, and a transmission rod passes through the end of the first connecting plate; when the rotating part rotates axially from the open locking position to the close locking position with the transmission rod as the rotation center, the extension direction of the second connecting plate is in the same direction as the second direction, so as to provide pressure along the second direction to the force-applying part, and the first direction is perpendicular to the second direction; when the rotating part rotates axially from the close locking position to the open locking position with the transmission rod as the rotation center, the extension direction of the second connecting plate has a preset angle with the second direction.

[0013] Optionally, an elastic element is provided between the pressure transmission component and the moving contact; the elastic element includes a force-bearing plate and an energy storage plate, the force-bearing plate abuts against the force-applying part; there are two energy storage plates, which are inclinedly arranged on opposite sides of the force-bearing plate so that the force-bearing plate and the top of the moving contact have a preset distance; the end of the energy storage plate away from the force-bearing plate abuts against the top of the moving contact and corresponds to the contact point position of the moving contact.

[0014] Optionally, the pressure device includes at least one pressure transmission component; when there are multiple pressure transmission components, the multiple pressure transmission components are spaced apart along the movement direction of the sliding component so as to correspond one-to-one with the moving contact.

[0015] In another aspect, the present invention provides a switch including a moving contact, a stationary contact, an operating mechanism, and a pressure device; the moving contact and the stationary contact are arranged opposite to each other, the pressure device includes a sliding member and a pressure transmission member, the pressure transmission member is drivenly connected to the moving contact, and the operating mechanism is drivenly connected to the sliding member; when the moving contact and the stationary contact are closed, the operating mechanism can drive the pressure transmission member through the sliding member to provide a gradually increasing pressure to the moving contact; when the moving contact and the stationary contact are open, the operating mechanism can drive the pressure transmission member through the sliding member to gradually decrease the pressure provided to the moving contact.

[0016] Optionally, the operating mechanism includes a rotating component and an energy storage component, with the ends of the rotating component being connected to the sliding component and the energy storage component respectively; the rotating component is driven to rotate in a preset direction, the energy storage component is subjected to force to store energy, and the sliding component is subjected to force to move in a first direction.

[0020] This application provides a pressure device, including a sliding member and a pressure transmission member. One end of the pressure transmission member is drivenly connected to the sliding member, and the other end is drivenly connected to the moving contact of a switch. When the moving contact closes with the stationary contact of the switch, the sliding member drives the pressure transmission member from the open lock position to the close lock position. During this movement, the pressure transmission member provides gradually increasing pressure to the moving contact, ensuring that the moving contact tightly contacts the stationary contact during closing, thus improving contact yield. When the moving contact opens with the stationary contact of the switch, the sliding member drives the pressure transmission member from the close lock position to the open lock position. During this movement, the pressure transmission member gradually reduces the pressure provided to the moving contact, allowing the moving contact to quickly disengage from the stationary contact with minimal resistance, significantly shortening the opening time, reducing the risk of failure, and minimizing impact on the operating mechanism, thereby extending equipment lifespan. The aforementioned pressure device can flexibly adjust the provided contact pressure under different contact states of the moving and stationary contacts, improving contact lifespan and operational safety.

[0021] This application also provides a switch, including a moving contact, a stationary contact, an operating mechanism, and a pressure device. The moving and stationary contacts are arranged opposite to each other. The pressure device includes a sliding element and a pressure transmission element. The pressure transmission element is drivenly connected to the moving contact, and the operating mechanism is drivenly connected to the sliding element. When the moving and stationary contacts are closed, the operating mechanism can drive the pressure transmission element through the sliding element to provide gradually increasing pressure to the moving contact, enabling the moving contact to tightly contact the stationary contact with appropriate pressure, ensuring good electrical contact between the contacts.

The above-mentioned switch can flexibly adjust the contact pressure provided by the pressure device in different contact states of the moving and stationary contacts, improving the contact service life and operational safety.

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0036] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0037] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0038] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0039] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0040] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0041] Please refer to Figure 3 In one aspect of the present invention, a pressure device 100 is provided, including a sliding member 111 and a pressure transmission member 121. One end of the pressure transmission member 121 is connected to the sliding member 111 in a transmission manner, and the other end is connected to the moving contact 210 of the switch 200 in a driving manner.

[0042] When the moving contact 210 closes with the stationary contact 220 of the switch 200, the sliding member 111 can drive the pressure transmission member 121 from the open lock position to the close lock position. During the movement, the pressure transmission member 121 can provide gradually increasing pressure to the moving contact 210. When the moving contact 210 opens with the stationary contact 220 of the switch 200, the sliding member 111 drives the pressure transmission member 121 from the close lock position to the open lock position. During the movement, the pressure transmission member 121 can gradually decrease the pressure provided to the moving contact 210.

[0043] Specifically, such as Figure 3 As shown, this application provides a pressure device 100, including a drive unit 110 and a pressure mechanism 120. The drive unit 110 includes a slider 111, which can slide smoothly and linearly along a first direction a, making its transmission process with the pressure mechanism 120 simpler and more efficient.

[0044] like Figure 4As shown, the pressure mechanism 120 includes a pressure transmission component 121. One end of the pressure transmission component 121 is connected to the sliding member 111, and the other end is connected to the moving contact 210. This allows the pressure transmission component 121 to convert the motion of the sliding member 111 into a force that can be applied to the moving contact 210. During the closing phase of the moving and stationary contacts 220, the pressure transmission component 121 ensures that the moving contact 210 obtains a stable contact pressure, ensuring that the moving contact 210 can tightly adhere to the stationary contact 220 at the moment of closing, reducing contact resistance and improving the current carrying capacity of the contacts. During the opening phase of the moving and stationary contacts 220, the pressure value provided by the pressure transmission component 121 gradually decreases, thereby ensuring rapid opening of the moving and stationary contacts 220, effectively reducing the risk of failure, and significantly reducing the impact on the operating mechanism 230 of the switch 200, extending the overall service life of the equipment.

[0045] It should be noted that, in one possible implementation of this application, such as Figure 3 As shown, the pressure device 100 includes at least one pressure transmission member 121. When there are multiple pressure transmission members 121, the movement directions of the sliding members 111 of the multiple pressure transmission members 121 are arranged at intervals to correspond one-to-one with the moving contacts 210. This application does not impose any limitation on the specific number of pressure transmission members 121, as long as it can ensure a correspondence with the number of moving contacts 210. With this arrangement, when the number of moving contacts 210 is large, the drive unit 110 can apply pressure to each moving contact 210 during closing through multiple pressure mechanisms 120, thereby improving the closing efficiency.

[0046] The pressure device 100 provided in this application includes a sliding member 111 and a pressure transmission member 121. One end of the pressure transmission member 121 is connected to the sliding member 111 in a transmission manner, and the other end is connected to the moving contact 210 of the switch 200 in a driving manner.

[0047] When the moving contact 210 closes with the stationary contact 220 of the switch 200, the sliding member 111 drives the pressure transmission member 121 from the open lock position to the close lock position. During the movement, the pressure transmission member 121 provides gradually increasing pressure to the moving contact 210, which is transmitted to the moving contact 210, thereby ensuring that the moving contact 210 is tightly attached to the stationary contact 220 during the closing process, improving the contact yield. When the moving contact 210 opens with the stationary contact 220 of the switch 200, the sliding member 111 drives the pressure transmission member 121 from the close lock position to the open lock position. During the movement, the pressure transmission member 121 gradually reduces the pressure provided to the moving contact 210, allowing the moving contact 210 to quickly disengage from the stationary contact 220 with minimal resistance, greatly shortening the opening time, reducing the risk of failure, and reducing the impact on the operating mechanism 230, thus extending the service life of the equipment. The pressure device 100 described above can flexibly adjust the contact pressure provided by the moving and stationary contacts 220 under different contact states, thereby improving the service life of the contacts and the safety of use.

[0048] In one possible implementation of this application, such as Figure 3 As shown, the pressure device 100 includes a drive unit 110, which includes a sliding member 111. The sliding member 111 includes a body 1111 and a linkage plate 1112. The opposite sides of the linkage plate 1112 are respectively connected to the body 1111 and the pressure transmission member 121. The linkage plate 1112 has a through hole 1112a, and the end of the pressure transmission member 121 is rotatably connected to the through hole 1112a.

[0049] Specifically, the body 1111 possesses sufficient strength and stability to ensure smooth linear sliding along a predetermined track under stress. The connection between the linkage plate 1112 and the body 1111 ensures that the linkage plate 1112 can move along with the body 1111, guaranteeing the continuity of power transmission. The connection between the linkage plate 1112 and the pressure transmission component 121 allows the linear motion characteristics of the body 1111 to be mechanically transmitted to the pressure transmission component 121. To ensure the uniformity of force transmission, preferably, the body 1111 is located in the middle of the linkage plate 1112.

[0050] To ensure that the movement of the linkage plate 1112 synchronously drives the rotation of the pressure transmission component 121, the linkage plate 1112 has a through hole 1112a, and the end of the pressure transmission component 121 is rotatably connected to the through hole 1112a. When the body 1111 drives the linkage plate 1112 to move along the first direction a, the through hole 1112a can move together with the linkage plate 1112, thereby driving the pressure transmission component 121 to rotate by a preset angle. The number of through holes 1112a corresponds to the number of pressure transmission components 121. When there are multiple through holes 1112a, the multiple through holes 1112a are evenly distributed along the first direction a.

[0051] Furthermore, such as Figure 4 and Figure 5 As shown, the inner wall of the through hole 1112a is provided with a transmission rod 1112b, and the pressure transmission component 121 includes a rotating part 1211 and a force-applying part 1212; one end of the rotating part 1211 is sleeved outside the transmission rod 1112b, and the other end is connected to the force-applying part 1212 in a transmission connection; the end of the force-applying part 1212 away from the rotating part 1211 is connected to the moving contact 210 in a driving connection.

[0052] When the moving contact 210 closes with the stationary contact 220 of the switch 200, the rotating part 1211 can rotate axially from the open lock position to the close lock position with the transmission rod 1112b as the rotation center. The rotating part 1211 can provide gradually increasing pressure to the force application part 1212 during the rotation process.

[0053] Specifically, such as Figure 5 As shown, the pressure transmission component 121 consists of two parts: a rotating part 1211 and a force-applying part 1212. In order to facilitate the synchronous rotation of the pressure transmission component 121 by the movement of the linkage plate 1112, a transmission rod 1112b is provided on the inner wall of the through hole 1112a. The transmission rod 1112b passes through the end of the rotating part 1211, ensuring that the rotating part 1211 has a stable rotation center during operation. It can accurately rotate axially around the transmission rod 1112b according to the linear motion of the sliding member 111 body 1111 and changes in external working conditions.

[0054] The other end of the rotating part 1211 establishes a reliable transmission connection with the force-applying part 1212. This connection can ensure the effective transmission of force and adapt to the angle changes during the rotation process, so that the power generated by the rotating part 1211 can be transmitted to the force-applying part 1212.

[0055] Optionally, such as Figure 2 , Figure 7 and Figure 8 As shown, the drive unit 110 includes a limiting shell 112, and a linkage plate 1112 is disposed inside the limiting shell 112. A sliding groove 1121 is provided on the top of the limiting shell 112 along the first direction a. The body 1111 passes through the sliding groove 1121 and can move along the sliding groove 1121. The first direction a is the movement direction of the sliding member 111.

[0056] Specifically, the limiting shell 112 is made of high-strength, wear-resistant material, thereby providing reliable physical protection for the linkage plate 1112, protecting it from external dust, moisture and possible mechanical collisions and other adverse factors, and ensuring the stable operation of the drive unit 110; in order to further improve the reliability and service life of the pressure device 100, the linkage plate 1112 and the pressure mechanism 120 are both set inside the limiting shell 112. Figure 7and Figure 8 As shown, the top of the limiting shell 112 is provided with a sliding groove 1121, and the body 1111 of the slider 111 can pass through the sliding groove 1121 and move along the sliding groove 1121. The sliding groove 1121 can limit the sliding path of the slider 111. At the same time, since the body 1111 is locked in the sliding groove 1121, the stability of the slider 111 during the sliding process can be further improved.

[0057] like Figure 9 As shown, the main body 1111 has a plug plate 1111a that can be inserted into the slide groove 1121; preferably, in order to further improve the sliding stability of the sliding member 111, the main body 1111 can have two plug plates 1111a. Correspondingly, the top of the limiting shell 112 also has two slide grooves 1121 opened along the first direction a, and the two plug plates 1111a are respectively inserted into the two slide grooves 1121.

[0058] It should be noted that, as Figure 2 As shown, in one specific embodiment of this application, an opening is provided at one end of the limiting shell 112 away from the slide groove 1121, and the elastic element 122 of the pressure mechanism 120 and the moving contact 210 of the switch 200 can extend outward from the opening.

[0059] For example, such as Figure 6 As shown, the rotating part 1211 includes a first connecting plate 1211a and a second connecting plate 1211b that are bent and connected. The transmission rod 1112b passes through the end of the first connecting plate 1211a. When the rotating part 1211 rotates axially from the open locking position to the closed locking position with the transmission rod 1112b as the rotation center, the extension direction of the second connecting plate 1211b is in the same direction as the second direction b, so as to provide pressure along the second direction b to the force application part 1212. The first direction a is perpendicular to the second direction b. When the rotating part 1211 rotates axially from the closed locking position to the open locking position with the transmission rod 1112b as the rotation center, the extension direction of the second connecting plate 1211b has a preset angle with the second direction b.

[0060] Specifically, such as Figure 6 As shown, the rotating part 1211 includes a first connecting plate 1211a and a second connecting plate 1211b that are bent and connected, so that the rotating part 1211 has a waist-like structure; the end of the first connecting plate 1211a is provided with a mounting hole for mounting the transmission rod 1112b; this arrangement ensures the stability and accuracy of the overall rotation process of the rotating part 1211, and also realizes the dynamic force and force transmission of the second connecting plate 1211b.

[0061] When switch 200 enters the closing operation process, the rotating part 1211, driven by external force, begins to rotate axially around the transmission rod 1112b until it reaches the closing lock position. At this time, the extension direction of the second connecting plate 1211b is consistent with the second direction b. This second direction b ensures optimal force transmission and precise control of contact pressure in the entire pressure device 100. When the second connecting plate 1211b is in the same direction as the second direction b, it can efficiently transmit the force accumulated during rotation to the force-applying part 1212 along this direction. The force-applying part 1212 then stably transmits the pressure to the moving contact 210, ultimately ensuring that the moving contact 210 obtains accurate, stable, and compliant contact pressure during closing, ensuring that the contact is tightly attached to the stationary contact 220, effectively reducing contact resistance, improving power transmission reliability, and meeting the normal operating conditions of the power system.

[0062] Correspondingly, during the opening operation phase of switch 200, the rotating part 1211 is also driven by external force to rotate axially around the transmission rod 1112b until it reaches the opening lock position. At this time, the extension direction of the second connecting plate 1211b forms a preset angle with the second direction b. This angle ensures that the rotating part 1211 does not apply additional pressure to the force-applying part 1212 during opening, which is detrimental to opening; at the same time, since the force-applying part 1212 no longer applies pressure to the moving contact 210, the moving contact 210 can quickly and smoothly disengage from the stationary contact 220, greatly shortening the opening time, reducing the risk of power system faults, ensuring equipment and line safety, and meeting the power system's requirements for rapid fault disconnection.

[0063] In one possible implementation of this application, such as Figure 4 As shown, an elastic element 122 is provided between the pressure transmission component 121 and the moving contact 210; the elastic element 122 includes a force-receiving plate 1221 and an energy storage plate 1222, the force-receiving plate 1221 abuts against the force-applying part 1212; there are two energy storage plates 1222, which are inclinedly arranged on opposite sides of the force-receiving plate 1221 so that the force-receiving plate 1221 and the top of the moving contact 210 have a preset distance; the end of the energy storage plate 1222 away from the force-receiving plate 1221 abuts against the top of the moving contact 210 and corresponds to the contact point position of the moving contact 210.

[0064] Specifically, the elastic element 122 is disposed between the pressure transmission element 121 and the moving contact 210. Utilizing its own elastic deformation characteristics, the elastic element 122 can receive the pressure transmitted by the pressure transmission element 121 during the closing phase of the moving and stationary contacts 220. Through its own elastic buffering and uniform dispersion, the moving contact 210 obtains a stable contact pressure, ensuring that the moving contact 210 can tightly fit the stationary contact 220 at the moment of closing, reducing contact resistance and improving the contact current carrying capacity. During the opening phase of the moving and stationary contacts 220, the elastic element 122 is no longer subjected to the pressure transmitted by the pressure transmission element 121, thereby restoring its initial shape, releasing the stored energy, ensuring the rapid opening of the moving and stationary contacts 220, and effectively reducing the risk of failure.

[0065] like Figure 4 As shown, the elastic element 122 includes a force-bearing plate 1221 and an energy storage plate 1222. The energy storage plate 1222 plays the role of energy storage and buffering in the elastic element 122. The two energy storage plates 1222 are inclinedly arranged on opposite sides of the force-bearing plate 1221, so that the elastic element 122 forms an arched structure, thereby reserving sufficient space for the elastic deformation of the energy storage plate 1222, ensuring the stable operation of the elastic element 122 under different working conditions, and maintaining the accuracy of pressure regulation of the switch 200. At the same time, it can also ensure that the energy stored in the energy storage plate 1222 and the energy released during pressure changes can directly act on the moving contact 210, realizing efficient energy transfer.

[0066] Another aspect of the embodiments of the present invention, such as Figure 1 As shown, a switch 200 is provided, including a moving contact 210, a stationary contact 220, an operating mechanism 230, and a pressure device 100. The moving contact 210 and the stationary contact 220 are arranged opposite to each other. The pressure device 100 includes a sliding member 111 and a pressure transmission member 121. The pressure transmission member 121 is drivenly connected to the moving contact 210, and the operating mechanism 230 is drivenly connected to the sliding member 111. When the moving contact 210 and the stationary contact 220 are closed, the operating mechanism 230 can drive the pressure transmission member 121 through the sliding member 111 to provide a gradually increasing pressure to the moving contact 210. When the moving contact 210 and the stationary contact 220 are open, the operating mechanism 230 can drive the pressure transmission member 121 through the sliding member 111 to gradually decrease the pressure provided to the moving contact 210.

[0067] Specifically, such as Figure 1As shown, the switch 200 includes a moving contact 210 and a stationary contact 220, which are arranged opposite to each other. Optionally, the contact method of the moving contact 210 and the stationary contact 220 can be clamping, translational, or rotary. This application does not impose any restrictions on this, as long as stable contact and closing can be ensured. To achieve more precise and efficient pressure control, the switch 200 also includes an operating mechanism 230. When the moving contact 210 and the stationary contact 220 are closed, the operating mechanism 230 can drive the pressure transmission component 121 to provide pressure to the moving contact 210 through the sliding member 111. When the moving contact 210 and the stationary contact 220 are open, the operating mechanism 230 can drive the pressure transmission component 121 through the sliding member 111 to gradually reduce the pressure provided to the moving contact 210. The specific structure and beneficial effects of the pressure device 100 have been described in detail above and will not be repeated here.

[0068] The aforementioned switch 200 can flexibly adjust the contact pressure provided by the pressure device 100 in different contact states of the moving and stationary contacts 220, thereby improving the contact life and safety of use.

[0069] Optionally, the operating mechanism 230 includes a rotating component 231 and an energy storage component 232. The ends of the rotating component 231 are respectively connected to the sliding component 111 and the energy storage component 232 in a transmission connection. The rotating component 231 is driven to rotate in a preset direction, the energy storage component 232 is subjected to force to store energy, and the sliding component 111 is subjected to force to move in the first direction a.

[0070] Specifically, the operating mechanism 230 includes a rotating component 231 and an energy storage component 232. The end of the rotating component 231 is connected to the sliding component 111 through a transmission connection. This connection ensures that the rotating component 231 can convert its rotational motion into the linear motion of the sliding component 111 during rotation, so that the sliding component 111 can move precisely along a predetermined first direction a, thereby driving the subsequent pressure transmission component 121 to move. At the same time, the end of the rotating component 231 is connected to the energy storage component 232 through a transmission connection. During the rotation of the rotating component 231, the energy storage component 232 can be subjected to force and store energy to provide a reset force for the subsequent reset of the rotating component 231 and the sliding component 111.

[0071] For example, such as Figure 10 and Figure 11As shown, the rotating component 231 includes a drive link 2311 and a first hinge plate 2312; the energy storage component 232 includes a second hinge plate 2321, an abutment 2322, and an energy storage spring 2323; the abutment 2322 is sleeved on the second hinge plate 2321, and the energy storage spring 2323 is sleeved on the outside of the second hinge plate 2321 and located in the middle of the abutment 2322; the first hinge plate 2312 is hinged to the second hinge plate 2321; the rotating component 231 also includes a connecting post 2313, one end of which is fixedly connected to the first hinge plate 2312, and the other end is fixedly connected to the sliding component 111;

[0072] The drive link 2311 is driven to rotate the first hinge plate 2312 and the second hinge plate 2321 in a preset direction, which can drive the connecting column 2313 to move the sliding member 111 in the first direction a, and compress the energy storage spring 2323 to store energy.

[0073] Specifically, such as Figure 10 and Figure 11 As shown, the rotating component 231 includes a driving link 2311 and a first hinge plate 2312. To ensure efficient force transmission, there can be multiple first hinge plates 2312, which are stacked along the second direction b. The driving link 2311 is stacked with and coaxially arranged with the multiple first hinge plates 2312. When the driving link 2311 rotates along a preset direction, it can synchronously drive the multiple first hinge plates 2312 to rotate axially.

[0074] like Figure 10 and Figure 11 As shown, the energy storage component 232 includes a second hinge plate 2321, which is hinged to the first hinge plate 2312. When the driving link 2311 rotates in a preset direction, it can synchronously drive the second hinge plate 2321 to rotate axially. An energy storage spring 2323 is sleeved on the end of the second hinge plate 2321 away from the first hinge plate 2312. Abutment members 2322 are respectively provided at both ends of the energy storage spring 2323, and the abutment members 2322 are slidably disposed on the second hinge plate 2321. When the driving link 2311 rotates in the preset direction, the first hinge plate 2312 can abut against the abutment member 2322, and gradually compress the abutment member 2322 during the axial rotation, so that the energy storage spring 2323 is compressed and stores energy, providing a restoring force for the subsequent reset of the driving link 2311, the first hinge plate 2312, and the second hinge plate 2321.

[0075] like Figure 11As shown, the connecting post 2313 connects the rotating member 231 and the sliding member 111. One end of the connecting post 2313 is fixedly connected to the first hinge plate 2312, ensuring that the connecting post 2313 can move synchronously with the first hinge plate 2312 during its rotation, converting the rotational power from the first hinge plate 2312 into the linear movement power of the sliding member 111, so that the sliding member 111 can move precisely along the predetermined first direction a. This fixed connection method ensures the effective transmission of force and avoids power loss during the transmission process.

For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0077] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, the present invention will not describe the various possible combinations separately.
