Description

Technical Field

[0001] This application relates to the field of transportation equipment technology, and more particularly to a sliding device. Background Technology

[0002] Sliding steer systems are important transport equipment. They typically consist of guide rails and sliding components, which move along the extension of the guide rails. The sliding components are driven by an additional drive mechanism and can carry the objects being transported. The drive mechanism moves the sliding components and the objects on them along the length of the guide rails.

[0003] However, the guide rail in the sliding device mentioned above cannot achieve the limiting braking of the sliding parts, which affects the safety of the sliding device. Utility Model Content

[0004] This application provides a sliding device to solve the technical problem in the above-mentioned related technologies where the guide rail in the sliding device cannot achieve the limiting braking of the sliding member, thus affecting the safety of the sliding device.

[0005] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0006] This application provides a sliding device, which includes:

[0007] A guide rail extends along a first direction, and the surface of the guide rail is provided with a plurality of first mounting grooves arranged at intervals along the first direction.

[0008] A sliding member is slidably connected to the guide rail, and the surface of the sliding member facing the first mounting groove has a limiting hole corresponding to the first mounting groove.

[0009] Multiple limiting mechanisms are provided, each of which is correspondingly disposed in each of the first mounting slots. Each limiting mechanism includes a driving component and a limiting member disposed in the first mounting slot.

[0010] The drive assembly is used to drive a portion of the limiting member into the limiting hole in the event of an emergency.

[0011] This application provides a sliding device that achieves dual safety protection through the cooperative structure of the guide rail and the sliding component. Multiple first mounting slots are spaced apart along the direction of movement on the guide rail surface, forming distributed braking nodes that spatially match the corresponding limiting holes on the sliding component. Each first mounting slot contains an independently configured limiting mechanism comprising a drive component and a limiting component. In case of an emergency, the drive component actively triggers the limiting component to insert into the limiting hole. This design overcomes the single-point failure risk of traditional brakes by achieving multi-point synchronous braking through a discretely arranged limiting mechanism. This avoids concentrated wear of internal components of the drive component and allows braking to be triggered at any position.

[0012] The drive assembly's built-in mounting slot design ensures a flat appearance for the equipment, preventing interference with normal sliding, while minimizing the braking response path. The plug-in connection between the limiting components and limiting holes completely eliminates wear caused by relative sliding of internal drive components, compared to the friction braking of gears, racks, or lead screws in existing technologies. Furthermore, in case of damage, only the single limiting mechanism needs to be replaced to restore function, greatly simplifying the maintenance process. This structure simultaneously meets the dual requirements of dynamic braking during operation and static fixation during transportation, fundamentally eliminating the risk of component breakage during transport by replacing traditional rope binding with physical plug-in connections.

[0018] Electromagnetic components;

[0019] An elastic element, one end of which is connected to the electromagnetic component, and the other end of which is connected to the limiting element;

[0020] The electromagnetic component magnetically attracts the limiting member when the sudden event does not occur, and the elastic member is compressed.

[0021] In the event of a power outage, the electromagnetic component loses its magnetism, and the elastic element drives a portion of the limiting element to insert into the limiting hole through its elastic force.

[0022] In one possible implementation, the electromagnetic component includes:

[0023] The base is disposed within the first mounting slot;

[0024] A conductive coil is wound around the outer periphery of the base, and when the conductive coil is energized, it causes the base to magnetically attract the limiting member.

[0025] In one possible implementation, a second mounting groove is provided at the bottom of the first mounting groove;

[0026] The electromagnetic component is disposed within the second mounting slot, and the electromagnetic component does not protrude from the opening of the second mounting slot.

[0027] In one possible implementation, a first insulating element is further included, which is disposed between the electromagnetic component and the wall of the second mounting groove.

[0028] One possible implementation also includes:

[0029] A first connector is disposed on the electromagnetic component and is used to connect one end of the elastic member; the first connector is insulated from the electromagnetic component.

[0030] The second connector is disposed on the limiting member and is used to connect the other end of the elastic member.

[0031] In one possible implementation, a second insulating element is also included;

[0032] The second insulating element is disposed between the limiting element and the wall of the first mounting groove.

[0033] In one possible implementation, the length of the limiting member inserted into the limiting hole is less than half the total length of the limiting member.

[0034] In one possible implementation, the guide rail includes two outer surfaces opposite each other along a second direction, each of the outer surfaces having a plurality of first mounting grooves;

[0035] The sliding member has a through groove, and the guide rail is inserted into the through groove;

[0036] The through groove includes two inner sidewalls opposite each other along the second direction, and each inner sidewall has a limiting hole.

[0037] In one possible implementation, the surface of the guide rail has a guide groove extending in a first direction, and the through groove has a guide protrusion corresponding to the guide groove, the guide protrusion being located within the guide groove. Attached Figure Description

[0059] As described in the background section, the guide rail in the sliding device of the aforementioned related technologies cannot achieve the limiting braking of the sliding parts, which affects the safety of the sliding device.

[0060] The problem arises because, in the event of an emergency during operation, the sliding steer equipment triggers an emergency brake on the drive mechanism to stop the sliding component from moving. The drive mechanism is typically a rotary motor, which transmits and outputs driving force to the sliding component via gears or ball screws. During emergency braking, the forced braking system often employs a motor-operated brake structure. This type of braking is prone to wear and breakage of mechanical contact surfaces in the event of a sudden power outage or emergency, leading to decreased motion accuracy and abnormal noise. Furthermore, ropes are used to secure moving parts during transport, but these ropes pose a risk of breakage, potentially damaging the equipment. Traditional braking mechanisms are complex to maintain, and replacing worn parts requires disassembling a large amount of the structure, impacting production efficiency.

[0061] To address the aforementioned issues, this application provides a sliding device that achieves dual safety assurance through a cooperative structure between the guide rail and the sliding component. Multiple first mounting slots are spaced apart along the direction of movement on the guide rail surface, forming distributed braking nodes that spatially match the corresponding limiting holes on the sliding component. Each first mounting slot contains an independently configured limiting mechanism comprising a drive component and a limiting component. In case of an emergency, the drive component actively triggers the limiting component to insert into the limiting hole. This design overcomes the single-point failure risk of traditional brakes by achieving multi-point synchronous braking through a discretely arranged limiting mechanism. This avoids concentrated wear of internal components of the drive component and allows braking to be triggered at any position.

[0062] The drive assembly's built-in mounting slot design ensures a flat appearance for the equipment, preventing interference with normal sliding, while minimizing the braking response path. The plug-in connection between the limiting components and limiting holes completely eliminates wear caused by relative sliding of internal drive components, compared to the friction braking of gears, racks, or lead screws in existing technologies. Furthermore, in case of damage, only the single limiting mechanism needs to be replaced to restore function, greatly simplifying the maintenance process. This structure simultaneously meets the dual requirements of dynamic braking during operation and static fixation during transportation, fundamentally eliminating the risk of component breakage during transport by replacing traditional rope binding with physical plug-in connections.

[0063] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0064] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 This application provides a sliding device, which may include a guide rail 100, a sliding member 200 and a plurality of limiting mechanisms 300.

[0065] Guide rail 100 along the first direction (e.g.) Figure 1 Extending in the X direction, the surface of the guide rail 100 has multiple first mounting grooves 110 spaced apart along the first direction. The guide rail 100 refers to the base structure that supports the linear movement of the sliding member 200, and can be made of a high-hardness alloy material with continuously distributed first mounting grooves 110 machined on its surface. The first mounting grooves 110 are equidistantly arranged along the direction of movement, forming discrete braking nodes to avoid stress concentration.

[0066] The slider 200 is slidably connected to the guide rail 100, and the surface of the slider 200 facing the first mounting groove 110 is provided with a limiting hole 210 corresponding to the first mounting groove 110.

[0067] Among them, the sliding component 200 refers to the functional component that moves along the guide rail 100. Its limiting hole 210 corresponds to the position of the first mounting groove 110, and the hole diameter is slightly larger than the cross-section of the limiting component 320 to ensure quick insertion.

[0068] In some embodiments, the slider 200 can be driven by an additional driving component, such as a rotary motor. The rotary motor is connected to the slider 200 via a structure such as a gear set or a ball screw, thereby enabling the rotary motor to drive the slider 200 to move along the extension direction of the guide rail 100.

[0069] Each limiting mechanism 300 is correspondingly disposed in each first mounting slot 110. The limiting mechanism 300 may include a drive component 310 and a limiting member 320 disposed in the first mounting slot 110. The limiting mechanism 300 refers to an independently disposed braking unit. Each unit includes an electromagnetic drive component 310 and a pin-type limiting member 320, which can be automatically triggered when power is lost.

[0070] The drive assembly 310 is used to drive a portion of the limiting member 320 into the limiting hole 210 in case of an emergency. The drive assembly 310 refers to a braking device based on electromagnetic principles, such as a combination structure including a coil and an elastic member 313, which releases elastic potential energy by de-energizing to push the limiting member 320.

[0071] In some embodiments, an emergency can refer to a malfunction in the sliding equipment during operation, requiring emergency braking. An emergency can also be caused by operator error requiring emergency braking. An emergency can also be a sudden power outage.

[0072] This application provides a sliding device that achieves dual safety protection through the cooperative structure of the guide rail 100 and the sliding member 200. Multiple first mounting grooves 110 are spaced apart along the direction of movement on the surface of the guide rail 100, forming distributed braking nodes that spatially match the corresponding limiting holes 210 on the sliding member 200. Each first mounting groove 110 contains an independently configured limiting mechanism 300, which includes a drive component 310 and a limiting member 320. In case of an emergency, the drive component 310 actively triggers the limiting member 320 to insert into the limiting hole 210. This design overcomes the single-point failure risk of traditional brakes by achieving multi-point synchronous braking through the discretely arranged limiting mechanisms 300, avoiding concentrated wear of internal components of the drive component and enabling braking to be triggered at any position.

[0073] The drive assembly 310 is integrated into the mounting slot, ensuring a flat appearance that doesn't hinder normal sliding while minimizing the braking response path. The plug-in connection between the limiting member 320 and the limiting hole 210 completely eliminates wear caused by relative sliding of internal parts compared to the friction braking of gears, racks, or lead screws in existing drive components. Furthermore, in case of damage, only the single limiting mechanism 300 needs to be replaced to restore function, greatly simplifying maintenance. This structure simultaneously meets the dual requirements of dynamic braking during operation and static fixation during transportation, fundamentally eliminating the risk of component breakage during transport by replacing traditional rope binding with physical plug-in connections.

[0074] In some embodiments, the sliding device can be electrically connected to a control system, which can control the start and stop of the drive assembly 310. When the control system provides a stop signal upon reaching a set position, the drive assembly drives the slider 200 in the opposite direction to prevent further movement of the slider 200. To prevent the slider 200 from slipping due to inertia, the control system can control the drive assembly 310 to drive the limiting member 320 to insert into the limiting hole 210 in the slider 200 to prevent the slider 200 from moving.

[0075] In some embodiments, when the slider 200 encounters loss of control or sudden power failure, the control system controls the drive assembly 310 to drive the limit member 320 to insert into the limit hole 210 in the slider 200, thereby preventing the slider 200 from continuing to run due to inertia, achieving the effect of forced braking and ensuring the safety of the equipment in emergency situations.

[0076] refer to Figure 2 In some embodiments, the length of the limiting member 320 inserted into the limiting hole 210 is less than half the total length of the limiting member 320.

[0077] This technical solution optimizes the stress distribution and operational reliability of the limiting member 320 from a structural design perspective by limiting the length ratio of the limiting member 320 inserted into the limiting hole 210. Specifically, by controlling the insertion length to less than half of the total length, the cantilever length of the extended portion of the limiting member 320 is reduced, thereby decreasing the bending stress concentration caused by impact loads during insertion and improving fracture resistance. On the other hand, retaining more than half the length of the limiting member 320 body as a supporting foundation ensures the structural stability of the limiting member 320 within the mounting groove and provides sufficient connection space for the drive assembly 310.

[0078] This proportional design also ensures that after an emergency is resolved, the limiting component 320 can quickly disengage from the limiting hole 210 to achieve reset, avoiding jamming caused by excessive insertion. At the same time, it shortens the disassembly stroke of the limiting component 320 during maintenance, improving the convenience of maintenance.

[0079] refer to Figure 2 , Figure 3 and Figure 5 , Figure 6 In some embodiments, the guide rail 100 may include a second direction (e.g., Figure 2 The two outer surfaces opposite each other in the Y direction have multiple first mounting grooves 110. The slider 200 has a through groove 220, and the guide rail 100 is inserted into the through groove 220. The through groove 220 may include two inner side walls opposite each other in the second direction, and each inner side wall has a limiting hole 210.

[0080] This technical solution provides first mounting grooves 110 on two opposite outer sides of the guide rail 100 in the second direction, and each first mounting groove 110 is provided with a limiting mechanism 300. This enables the guide rail 100 to limit the sliding member 200 on both sides in the second direction, improving the limiting stability of the sliding member 200 and thus improving the braking performance of the sliding device.

[0081] refer to Figure 2 , Figure 4 , Figure 5 and Figure 6In some embodiments, the surface of the guide rail 100 has a guide groove 130 extending in a first direction, and the through groove 220 has a guide protrusion 230 corresponding to the guide groove 130, the guide protrusion 230 being located within the guide groove 130.

[0082] This technical solution involves setting the guide protrusion 230 on the slider 200 within the guide groove 130, thereby limiting the slider 200 in the height direction through the groove wall of the guide groove 130. This prevents the slider 200 from separating from the guide rail 100, improves the connection stability between the slider 200 and the guide rail 100, and enhances the motion stability of the slider 200 during its sliding relative to the guide rail 100.

[0083] refer to Figure 4 , Figure 7 and Figure 8 In some embodiments, the sliding device may further include a connector 400 disposed at one end of the limiting member 320 facing the drive assembly 310, and the drive assembly 310 having a slot 311 adapted to the connector 400, the connector 400 being interference-fitted into the slot 311.

[0084] In a specific implementation, if the drive component 310 is to drive the limiting member 320 to extend out of the first mounting slot 110, the driving force of the drive component 310 needs to be greater than the engagement force between the plug 400 and the slot 311.

[0085] This technical solution achieves reliable connection and convenient maintenance of the limiting mechanism 300 during sudden braking by setting an interference fit structure between the connector 400 and the slot 311 on the drive assembly 310. Specifically, the connector 400 is located at the end of the limiting member 320 near the drive assembly 310, forming a physical connection interface. The slot 311 in the drive assembly 310 matches the shape of the connector 400, and a tight connection is formed by the radial pressure generated by the interference fit.

[0086] This structure effectively transmits the driving force of the drive assembly 310 to the limiting member 320 during sudden braking, preventing braking delay or failure due to connection gaps. During maintenance and replacement, the interference fit ensures connection stability under normal operating conditions and allows damaged parts to be pulled out directly by external force, significantly reducing disassembly difficulty compared to traditional welding or threaded connections.

[0087] The axial positioning design of the connector 400 ensures that the force transmission path between the drive assembly 310 and the limiting member 320 is minimized, improving braking response speed. The interference fit control balances the requirements for connection strength and disassembly, ensuring braking reliability while meeting the requirements for quick maintenance.

[0088] Furthermore, by setting the connector 400, the limit member 320 can be prevented from extending out of the first mounting slot 110 without any sudden events or without being driven by the non-driving component 310, thus preventing incorrect limiting and improving the working stability of the limit mechanism 300.

[0089] refer to Figure 4 , Figure 7 and Figure 8 In some embodiments, there are multiple connectors 400 and multiple slots 311, with each connector 400 being inserted into a corresponding slot 311.

[0090] This technical solution, by designing multiple connectors 400 and multiple slots 311, can realize multi-point connection between the limiting member 320 and the driving component 310, which can improve the connection stability between the limiting member 320 and the driving component 310 and prevent the limiting member 320 from extending out of the first mounting slot 110 when not driven by the driving component 310.

[0091] refer to Figure 4 , Figure 7 and Figure 8 In some embodiments, the drive component 310 may include an electromagnetic component 312 and an elastic element 313.

[0092] Among them, the electromagnetic component 312 refers to the device that uses electromagnetic force to attract the limiting member 320. Specifically, it can be implemented by using an iron core structure with a conductive coil, which generates magnetic attraction to fix the limiting member 320 when energized.

[0093] One end of the elastic element 313 is connected to the electromagnetic component 312, and the other end is connected to the limiting element 320. The elastic element 313 refers to a mechanical element with elastic energy storage capacity, which can be implemented by using a helical spring or a disc spring. It stores elastic force in the compressed state and provides driving force when released.

[0094] In the absence of any sudden event, the electromagnetic component 312 compresses the magnetically attracted limiting member 320 and the elastic member 313. The limiting member 320 refers to the mechanical component used to insert into the limiting hole 210, which can be implemented using a cylindrical pin or a wedge block, achieving forced braking through physical obstruction.

[0095] In the event of a power outage, the electromagnetic component 312 loses its magnetism, and the elastic element 313 drives a portion of the limiting element 320 to insert into the limiting hole 210 through its elastic force.

[0096] This technical solution achieves a dual control mechanism through the synergistic effect of the electromagnetic component 312 and the elastic element 313. Under normal power supply conditions, the magnetic attraction generated by the electromagnetic component 312 overcomes the elastic force of the elastic element 313, attracting and fixing the limiting element 320. At this time, the elastic element 313 is in a compressed, energy-storing state. When a sudden power failure occurs, the electromagnetic component 312 immediately loses its magnetism, releasing the constraint on the limiting element 320. The compressed elastic element 313 rapidly releases its stored elastic potential energy, pushing the limiting element 320 to quickly insert into the limiting hole 210 of the sliding element 200 to complete the mechanical locking.

[0097] This design achieves dual protection through electric drive and mechanical energy storage. The active attraction of the electromagnetic component 312 ensures that the limit switch will not be accidentally triggered during normal operation, while the passive release mechanism of the elastic component 313 ensures that braking action can be automatically performed without external energy in emergency situations such as power outages. In particular, the two ends of the elastic component 313 are connected to the electromagnetic component 312 and the limit component 320 respectively, forming a direct force transmission path, which maximizes energy conversion efficiency; the magnetic attraction state of the electromagnetic component 312 is directly related to the power supply state of the equipment, forming intrinsically safe control logic.

[0098] refer to Figure 4 , Figure 7 and Figure 8 In some embodiments, the electromagnetic component 312 may include a base 3121 and a conductive coil.

[0099] The base 3121 is disposed in the first mounting groove 110, and the conductive coil is wound around the outer periphery of the base 3121. When the conductive coil is energized, the base 3121 magnetically attracts the limiting member 320.

[0100] The base 3121 refers to the support structure used to support the conductive coil. Specifically, it can be a cuboid or cylindrical structure made of magnetically conductive material, and the electromagnetic component 312 is fixedly installed by embedding it into the first mounting groove 110. The conductive coil refers to the conductive wire wound around the outer periphery of the base 3121. Specifically, it can be made of copper wire or aluminum wire wound evenly in a spiral manner, and the base 3121 forms a closed magnetic circuit by passing electricity through it.

[0101] This technical solution achieves functional integration and optimized installation of the electromagnetic component 312 through the coordinated operation of the base 3121 and the conductive coil. The base 3121, as the supporting structure, is fixed within the first mounting groove 110, providing a stable physical support foundation for the conductive coil and avoiding the risk of displacement of the electromagnetic component 312 due to vibration during operation on the guide rail 100. The conductive coil is wound around the outer circumference of the base 3121 in a circumferential structure. This circumferential distribution maximizes the contact area between the coil and the base 3121 and forms a closed magnetic circuit through the magnetic permeability of the base 3121, enabling the base 3121 to generate a uniform and concentrated magnetic field when energized.

[0102] When current passes through the conductive coil, the base 3121 is magnetized as a whole, forming a strongly magnetic body. This magnetization method has a higher magnetic energy utilization rate compared to local magnetization, ensuring that the attraction force on the limiting member 320 meets the design requirements. At the same time, as the core carrier of the electromagnetic component 312, the base 3121, with its structure embedded in the first mounting groove 110, not only achieves concealed installation of the electromagnetic component 312, but also enhances the impact resistance of the overall structure through the constraint effect of the groove wall.

[0103] refer to Figure 4 , Figure 7 and Figure 8 In some embodiments, a second mounting groove 120 is provided at the bottom of the first mounting groove 110, and the electromagnetic component 312 is disposed in the second mounting groove 120, and the electromagnetic component 312 does not protrude from the opening of the second mounting groove 120.

[0104] The second mounting groove 120 refers to the groove structure that extends downward from the bottom of the first mounting groove 110. Specifically, it can be achieved by machining or casting to form a recessed area at the bottom of the first mounting groove 110. Its function is to provide a space for the electromagnetic component 312.

[0105] By creating a second mounting groove 120 at the bottom of the first mounting groove 110, the electromagnetic component 312 is completely embedded inside the second mounting groove 120, ensuring that it does not protrude from the groove opening. This structural design effectively avoids direct contact or interference between the electromagnetic component 312 and the slider 200 or other moving parts during normal sliding. The layout of the electromagnetic component 312 being built into the second mounting groove 120 protects the electromagnetic component 312 from external mechanical impacts and maintains the flatness of the guide rail 100 surface, thereby reducing the frictional resistance when the slider 200 moves.

[0106] Meanwhile, the concealed installation of the electromagnetic component 312 can prevent accidental collisions or wear caused by the protruding part, extend the service life of the electromagnetic component 312, and ensure the stability of the magnetic interaction between the electromagnetic component 312 and the limiting member 320 during emergency braking.

[0107] refer to Figure 4 , Figure 7 and Figure 8 In some embodiments, the sliding device may further include a first insulating element (not shown in the figure) disposed between the electromagnetic component 312 and the wall of the second mounting groove 120.

[0108] The first insulating element refers to a non-conductive insulating layer disposed between the electromagnetic component 312 and the inner wall of the second mounting groove 120. Specifically, it can be made of insulating materials such as rubber, polytetrafluoroethylene, or engineering plastics, and its shape matches the contour of the wall of the second mounting groove 120. This insulating layer, through physical isolation, blocks direct contact between the electromagnetic component 312 and the metal guide rail 100, preventing current from being conducted through the guide rail 100.

[0109] This technical solution achieves physical isolation between the electromagnetic component 312 and the main structure of the guide rail 100 by setting a first insulating element between the electromagnetic component 312 and the wall of the second mounting groove 120. Since the electromagnetic component 312 typically contains energized parts such as conductive coils, direct contact with the metal wall of the guide rail 100 could lead to leakage or short circuit risks. The intervention of the first insulating element blocks the current conduction path, preventing electrical faults caused by accidental contact between the electromagnetic component 312 and the guide rail 100, and reducing safety hazards caused by metal contact when the equipment is powered off. This insulation design also reduces frictional losses between the electromagnetic component 312 and the guide rail 100 during transportation, and provides a stable insulating environment for the action of the elastic element 313 driving the limiting element 320 in the event of a sudden power outage, ensuring the reliability of the forced braking process.

[0110] refer to Figure 4 , Figure 7 and Figure 8 In some embodiments, the sliding device may further include a first connector 500 and a second connector 600.

[0111] The first connector 500 is disposed on the electromagnetic component 312 and is used to connect one end of the elastic member 313. The first connector 500 is insulated from the electromagnetic component 312. The second connector 600 is disposed on the limiting member 320 and is used to connect the other end of the elastic member 313.

[0112] The first connector 500 refers to a mechanical structure used to fix one end of the elastic member 313. Specifically, it can be implemented by a connecting block or sleeve made of insulating material. Its function is to cut off the conductive path between the elastic member 313 and the electromagnetic component 312, so as to prevent current from being conducted through the elastic member 313.

[0113] The second connector 600 refers to the mechanical structure used to fix the other end of the elastic member 313. Specifically, it can be implemented by a connecting ring or hook made of metal or non-metal materials. Its function is to transmit the elastic force of the elastic member 313 to the limiting member 320, so as to ensure that the limiting member 320 is reliably driven when power is lost.

[0114] Among them, the insulation connection refers to the method of blocking the current path through physical isolation or non-conductive materials. Specifically, insulating materials such as ceramics, plastics or rubber can be used as the isolation layer between the first connector 500 and the electromagnetic component 312. Its function is to prevent the current generated when the electromagnetic component 312 is energized from interfering with the movement of the elastic component 313 or causing a short circuit.

[0115] This technical solution achieves electrical isolation between the electromagnetic component 312 and the elastic component 313 by setting up an insulated first connector 500 and a second connector 600. The first connector 500 is fixed to the electromagnetic component 312 and connected to one end of the elastic component 313. Its insulated connection prevents the current generated when the electromagnetic component 312 is energized from being conducted to the elastic component 313 through the connector, thereby preventing the elastic component 313 from short-circuiting due to conductivity or interfering with the magnetic attraction of the electromagnetic component 312. The second connector 600 is fixed to the limiting component 320 and connected to the other end of the elastic component 313, ensuring that the elastic force of the elastic component 313 can directly act on the limiting component 320, so that it can reliably pop out without electromagnetic interference when power is lost. Through the insulated design between the first connector 500 and the electromagnetic component 312, the physical connection stability between the elastic component 313 and the electromagnetic component 312 is guaranteed, and the risk of electromagnetic attraction force attenuation or abnormal discharge due to conductivity is eliminated, thereby improving the response reliability of the limiting mechanism 300 in emergency situations.

[0116] refer to Figure 4 , Figure 7 and Figure 8 In some embodiments, the sliding device may further include a second insulating element (not shown in the figure), which is disposed between the limiting member 320 and the wall of the first mounting groove 110.

[0117] The second insulating element refers to a non-conductive insulating layer disposed between the limiting member 320 and the mounting groove of the guide rail 100, which can be implemented using a thin sheet structure made of polytetrafluoroethylene or ceramic material. This insulating layer is used to block direct conductive contact between the limiting member 320 and the guide rail 100.

[0118] The wall of the first mounting groove 110 is a metal structural surface on both sides and bottom of the groove opened on the surface of the guide rail 100, which can be formed by processing aluminum alloy or stainless steel. This structural surface forms a mechanical fit with the limiting member 320.

[0119] By adding a second insulating component between the limiting member 320 and the wall of the first mounting groove 110, this technical solution achieves physical isolation of the current path of the electromagnetic component 312 during operation. The second insulating component effectively blocks direct contact between the limiting member 320 and the conductive guide rail 100, preventing leakage current that may be generated when the electromagnetic component 312 is energized from being conducted to the guide rail 100 through the limiting member 320, and also preventing arc discharge caused by potential difference between the guide rail 100 and the limiting member 320.

[0120] This insulation structure ensures the normal magnetic attraction function of the electromagnetic drive component 310 while eliminating the electromagnetic interference conduction path caused by metal contact, ensuring that the movement trajectory of the limit component 320 is not disturbed by electromagnetic residual force when the elastic component 313 releases energy.

[0121] From a mechanical structure perspective, the insulation layer also reduces the risk of electrochemical corrosion caused by long-term friction between the limiting component 320 and the metal wall of the mounting groove, thereby maintaining the rapid response characteristics of the limiting mechanism 300 in the event of a sudden power failure.

[0123] It should be noted that phrases such as "in particular implementation," "in some embodiments," "in this embodiment," and "exemplarily" used in the specification indicate that the described embodiments may include specific features, structures, or characteristics, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, such phrases may not necessarily refer to the same embodiment. Moreover, when describing a specific feature, structure, or characteristic in conjunction with embodiments, implementing such a feature, structure, or characteristic in conjunction with other embodiments, whether explicitly described or not, is within the knowledge scope of those skilled in the art.

[0124] Generally speaking, terms should be understood at least in part by their use in context. For example, at least in part by context, the term "one or more" as used in the text can be used to describe any feature, structure, or characteristic of the singular meaning, or a combination of features, structures, or characteristics of the plural meaning. Similarly, at least in part by context, terms such as "a" or "the" can also be understood to convey either singular or plural usage.

[0125] It should be readily understood that the terms “on,” “above,” and “on top of” in this disclosure should be interpreted in the broadest possible sense, such that “on” means not only “directly on something” but also “on something” with an intermediate feature or layer therebetween, and that “above” or “on top of” means not only “on top of something” but also “on top of something” without an intermediate feature or layer therebetween (i.e., directly on something).

[0126] Furthermore, for ease of explanation, spatially relative terms such as "below," "below," "under," "above," and "above" may be used to describe the relationship of one element or feature relative to other elements or features as shown in the figures. Spatially relative terms are intended to encompass different orientations of the device in use or operation other than those shown in the figures. The device may have other orientations (rotated 90 degrees or in other orientations), and the spatially relative descriptive terms used herein may be interpreted accordingly.
