Description

Technical Field

[0001] This utility model relates to the field of components technology for electromechanical products, and more specifically, to a telescopic motion actuator assembly and an electromechanical product. Background Technology

[0002] With the rise of the new fourth generation of automobiles (electrification, connectivity, intelligence, and sharing) and electric vehicles, a variety of electromechanical products have emerged, such as electric charging port covers and electric glove boxes.

[0003] In related technologies, most of these electromechanical products use telescopic motion actuators. Taking an electric glove box as an example, the electric glove box mainly includes an electric telescopic motion actuator and a pull-out box. The electric telescopic motion actuator mainly includes a motor, a transmission mechanism, and a locking pin. The motor is used to drive the transmission mechanism to drive the locking pin to insert or disengage from the opening of the vehicle, so as to lock and unlock the pull-out box.

[0004] However, if the motor or transmission mechanism malfunctions when the locking pin extends to insert into the vehicle's opening, the locking pin may not retract, and the pull-out box may remain in a fixed state, unable to be opened and used, thus affecting the normal use of electromechanical products such as electric glove boxes. Utility Model Content

[0005] The problem solved by this utility model is that the driving component or transmission mechanism of the telescopic motion actuator malfunctions, affecting the normal use of electromechanical products.

[0006] To solve the above problems, this utility model provides a telescopic motion actuator assembly and electromechanical products.

[0007] In a first aspect, this utility model provides a telescopic motion actuator assembly, including an actuator and an unlocking structure. The actuator includes a moving rod, a housing, and a driving component and a transmission mechanism disposed within the housing. The moving rod includes a rod body and a locking pin, the locking pin being disposed at the end of the rod body and used to insert into or disengage from a locked component of an electromechanical product. At least a portion of the rod body is disposed within the housing. The driving component is connected to the transmission mechanism and is used to drive the transmission mechanism to move. The transmission mechanism is movably connected to the moving rod and is used to drive the moving rod to extend or automatically return to its original position.

[0008] The housing is provided with a strip-shaped hole, the extension direction of which is parallel to the extension direction of the moving rod. One of the moving rod and the unlocking structure passes through the strip-shaped hole and is connected to the other of the moving rod and the unlocking structure. The unlocking structure is used to drive the moving rod to perform a manual return action relative to the transmission mechanism along a first direction.

[0009] Optionally, the movable rod further includes a boss, which is disposed on the rod body and passes through the strip hole. Along the extension direction of the movable rod, the size of the strip hole is larger than the size of the boss. The unlocking structure is connected to the boss and is used to manually return the rod body to its original position via the boss.

[0010] Optionally, the actuator further includes a dust cap, which is fixed to the housing at a position corresponding to the strip hole. The unlocking structure is connected to the dust cap. The dust cap is a housing structure with an opening at one end facing the housing and a first cavity inside. The part of the boss that passes through the strip hole is located in the first cavity, and the boss is used to move along the first direction within the first cavity.

[0011] Optionally, the unlocking structure includes a pull wire portion and a connecting portion. The connecting portion is connected to the end of the pull wire portion. The connecting portion is provided with a connecting hole. The connecting hole of the connecting portion is fitted onto the dust cap. The dust cap is used to deform under the pulling force transmitted to the connecting portion, so as to drive the boss to perform a manual return action.

[0012] Optionally, the unlocking structure further includes an extension portion, the extension portion is provided at the end of the connecting portion along the second direction, the housing includes a guide portion, the guide portion and the dust cap are arranged at intervals along the second direction, the extension portion is slidably connected to the guide portion, and the second direction is perpendicular to the first direction.

[0013] Optionally, the housing further includes a limiting part, the pull wire part passes through the limiting part, and the limiting part and the dust cap are spaced apart along the first direction.

[0014] Optionally, the dust cap protrudes from the surface of the housing.

[0015] Optionally, the housing has a through hole to facilitate the passage of the rod body; the movable rod further includes a limiting member disposed on the rod body and located outside the housing, wherein the size of the movable rod at the limiting member is larger than the size of the through hole.

[0016] Optionally, the transmission mechanism includes a gear assembly and a rotating shaft, the driving device is connected to the gear assembly, one end of the rotating shaft is fixedly connected to the gear assembly, and the end of the rotating shaft away from the gear assembly is threadedly connected to the rod body;

[0017] The movable rod also includes a limiting rod structure, which extends along a third direction and is connected to the rod body. The inner wall of the housing is provided with a limiting groove, which extends along the first direction. A portion of the limiting rod structure is slidably connected to the limiting groove. The limiting rod structure is used to limit the rotation of the rod body. The third direction is perpendicular to the first direction.

[0018] Optionally, the rod body is a sleeve structure with internal threads, the end of the rotating shaft away from the gear assembly is provided with external threads, the rod body is sleeved on the rotating shaft, and the internal threads of the rod body are threadedly connected to the external threads of the rotating shaft.

[0019] Secondly, this utility model provides an electromechanical product, including a locked component and a telescopic motion actuator assembly as described above.

[0020] The beneficial effects of this utility model of telescopic motion actuator assembly and electromechanical product are:

[0021] Since the drive components and transmission mechanism are housed within the housing, the housing provides mounting space for them. The actuator can operate in such a way that the locking pin can be inserted into or disengaged from the lock hole of the locked part of the electromechanical product. For example, when the drive component drives the transmission mechanism in the first operating mode, it can cause the locking pin of the moving rod to extend relative to the housing, allowing the locking pin to be inserted into the lock hole of the locked part, thereby achieving the locking function of the actuator. When the drive component drives the transmission mechanism in the second operating mode, it can cause the locking pin of the moving rod to automatically return relative to the housing, allowing the locking pin to automatically disengage from the lock hole of the locked part, thereby achieving the automatic unlocking function of the actuator.

[0022] Because the housing has a slotted hole, it is convenient for the rod body inside the housing to connect with the unlocking structure outside the housing. If the locking pin of the moving rod is in the extended position and the driving device or transmission mechanism malfunctions, a pulling force can be applied to the unlocking structure manually. This will cause the moving rod to manually return to its original position relative to the transmission mechanism in the first direction. The locking pin of the moving rod can be disengaged from the lock hole of the locked part under manual pulling force, thereby realizing the manual unlocking function of the actuator. This ensures that the locked part of the electromechanical product can still be used normally even if the driving device and transmission mechanism malfunction. Attached Figure Description

[0043] To address the problems existing in the aforementioned related technologies, this embodiment provides a telescopic motion actuator assembly and electromechanical product.

[0044] like Figures 1 to 3 As shown in the figure, an embodiment of the present invention provides a telescopic motion actuator assembly, including an actuator 2 and an unlocking structure 1. The actuator 2 includes a moving rod 22, a housing 21, and a driving device 23 and a transmission mechanism 24 disposed within the housing 21. The moving rod 22 includes a rod body 221 and a locking pin 222. The locking pin 222 is disposed at the end of the rod body 221 and is used to insert into or disengage from the locked part of the electromechanical product. At least a portion of the rod body 221 is disposed within the housing 21. The driving device 23 is connected to the transmission mechanism 24 and is used to drive the transmission mechanism 24 to move. The transmission mechanism 24 is movably connected to the moving rod 22 and is used to drive the moving rod 22 to extend or automatically return to its original position.

[0045] The housing 21 is provided with a strip-shaped hole 2121. The extension direction of the strip-shaped hole 2121 is parallel to the extension direction of the moving rod 22. One of the moving rod 22 and the unlocking structure 1 passes through the strip-shaped hole 2121 and is connected to the other of the moving rod 22 and the unlocking structure 1. The unlocking structure 1 is used to drive the moving rod 22 to perform a manual return action relative to the transmission mechanism 24 along a first direction.

[0046] Specifically, the first direction refers to the extension direction of the moving rod 22, which can be related to... Figure 2 The Y-axis is parallel in the coordinate system. The locking pin 222 is located at the end of the extension direction of the rod body 221, and the two can be an integral structure to ensure the mechanical strength of the moving rod 22.

[0047] The statement that at least a portion of the rod body 221 is disposed within the housing 21 means that the entire rod body 221 is disposed inside the housing 21, or that a portion of the rod body 221 is disposed inside the housing 21; the locking pin 222 is disposed on the outside of the housing 21.

[0048] The locked component is a movable part in an electromechanical product; for example, if the electromechanical product is an electric glove box of a vehicle, the locked component may be a pull-out box that can be opened or closed in the electric glove box; if the electromechanical product is an electric charging port cover of a vehicle, the locked component may be a charging cover that can be opened or closed in the electric charging port cover; if the electromechanical product is an electric fuel tank cap structure of a vehicle, the locked component may be a fuel tank cap that can be opened or closed in the electric fuel tank cap structure.

[0049] The movable connection between the transmission mechanism 24 and the movable rod 22 means that the movable rod 22 can extend or retract relative to the transmission mechanism 24 along a first direction. In other words, the transmission mechanism 24 and the movable rod 22 can generate relative motion, or rather, they do not rotate or move synchronously. Specifically, the direction of the extension of the movable rod 22 relative to the housing 21 can be... Figure 2 In the coordinate system, the positive Y-axis is the same, and the direction of the automatic return action (or manual return action) of the moving rod 22 relative to the housing 21 can be the same as... Figure 2 In the coordinate system, the Y-axis has the same direction of rotation.

[0050] The extension direction of the moving rod 22 and the extension direction of the strip hole 2121 can be... Figure 2 The Y-axis is parallel in the coordinate system; the slot 2121 of the housing 21 facilitates the connection 12 between the moving rod 22 and the locking structure within the slot 2121. Figure 2 The forward or reverse movement of the Y-axis in the coordinate system.

[0051] One of the moving rod 22 and the unlocking structure 1 passing through the strip hole 2121 and being connected to the other of the moving rod 22 and the unlocking structure 1 means that a part of the unlocking structure 1 passes through the strip hole 2121 and is connected to the moving rod 22 inside the housing 21, or a part of the moving rod 22 extends out of the housing 21 from the strip hole 2121 and is connected to the unlocking structure 1.

[0052] In this embodiment, since the driving device 23 and the transmission mechanism 24 are disposed within the housing 21, the housing 21 provides installation space for the driving device 23 and the transmission mechanism 24. The actuator 2 can operate in such a way that the locking pin 222 can be inserted into or disengaged from the locking hole of the locked part of the electromechanical product. For example, when the driving device 23 drives the transmission mechanism 24 to move in the first working mode, the locking pin 222 of the moving rod 22 can be driven to extend relative to the housing 21 (i.e., along...). Figure 2 (Moving in the positive Y-axis direction in the coordinate system) allows the locking pin 222 to be inserted into the lock hole of the locked part, thereby realizing the locking function of the actuator 2; when the driving device 23 drives the transmission mechanism 24 to move in the second working mode, it can drive the locking pin 222 of the moving rod 22 to perform an automatic return action relative to the housing 21 (i.e., along the...) Figure 2(Move in the opposite direction of the Y-axis in the coordinate system) so that the locking pin 222 can automatically disengage from the lock hole of the locked part, thereby realizing the automatic unlocking function of the actuator 2.

[0053] Because the housing 21 has a slotted hole 2121, it facilitates the connection between the rod body 221 inside the housing 21 and the unlocking structure 1 outside the housing 21; if the locking pin 222 of the moving rod 22 is in the extended position and the driving device 23 or the transmission mechanism 24 malfunctions, a pulling force can be manually applied to the unlocking structure 1 to drive the moving rod 22 to manually return to its original position relative to the transmission mechanism 24 in the first direction (i.e., along...). Figure 2 (Moving in the opposite direction of the Y-axis in the coordinate system) allows the locking pin 222 of the moving rod 22 to disengage from the locking hole of the locked part under manual pulling force, thereby realizing the manual unlocking function of the actuator 2. This ensures that the locked part of the electromechanical product can still be used normally even if the driving device 23 and the transmission mechanism 24 fail. The direction of the manual pulling force can be in the opposite direction of the Y-axis movement. Figure 2 In the coordinate system, the Y-axis points in the same opposite direction.

[0054] The driving device 23 and the transmission mechanism 24 can be implemented in the following two ways, as exemplarily described. First, if the driving device 23 is an air pump, the transmission mechanism 24 can be a combination structure of an air exchange valve and a telescopic cylinder. The moving rod 22 can be the piston rod of the telescopic cylinder. The piston rod can extend or automatically (or manually) return to its original position relative to the housing 21 in the first direction under the reversing action of the air exchange valve. In the first working mode, the rod chamber of the telescopic cylinder can be filled with air to realize the extension action of the piston rod. In the second working mode, the rodless chamber of the telescopic cylinder can be filled with air to realize the automatic return action of the piston rod.

[0055] The second type, combining Figure 3 and Figure 11 As shown, if the driving device 23 is a rotary motor, the transmission mechanism 24 may include a gear assembly 241 and a rotating shaft 242. The moving rod 22 can convert the rotational motion of the rotating shaft 242 into its own linear motion along a first direction to perform an extension or retraction action. The first working mode can be the clockwise rotation of the gear assembly 241 to realize the extension action of the moving rod 22. The second working mode can be the counterclockwise rotation of the gear assembly 241 to realize the automatic retraction action of the piston rod.

[0056] Optionally, combined Figure 2 , Figure 4 and Figure 5As shown, the movable rod 22 also includes a boss 223, which is disposed on the rod body 221. The boss 223 passes through the strip hole 2121. Along the extension direction of the movable rod 22, the size of the strip hole 2121 is larger than the size of the boss 223. The unlocking structure 1 is connected to the boss 223 and is used to drive the rod body 221 to perform a manual return action through the boss 223.

[0057] Specifically, in combination Figure 3 , Figure 5 , Figure 8 , Figure 10 and Figure 11 As shown, the housing 21 has a second cavity. The housing 21 may include a bottom shell 211 and a cover 212. At least one of the bottom shell 211 and the cover 212 has a cavity structure. When the bottom shell 211 and the cover 212 are assembled together, a second cavity is formed. The driving device 23 and the transmission mechanism 24 are installed in the second cavity formed by the bottom shell 211 and the cover 212. Figure 11 As shown, the housing 21 also includes a plurality of fasteners 215, and the bottom shell 211 and the cover 212 can be connected and fixed by the plurality of fasteners 215, wherein the fasteners 215 can be bolt fasteners 215.

[0058] Combination Figure 5 As shown, the cover 212 of the housing 21 may be provided with the strip-shaped hole 2121; the boss 223 along Figure 4 The Z-axis direction is set on the rod body 221. The boss 223 is perpendicular to the extension direction of the rod body 221. The boss 223 and the rod body 221 can be an integral structure to ensure the mechanical strength of the moving rod 22.

[0059] The extension direction of the movable rod 22 can be... Figure 4 and Figure 5 The Y-axis is parallel in the coordinate system; along the extension direction of the moving rod 22, the size (i.e., length) of the strip hole 2121 is greater than the size (length) of the boss 223, thereby ensuring that the boss 223 can move smoothly within the strip hole 2121 along the first direction.

[0060] The unlocking structure 1 can be directly connected to the boss 223, or the unlocking structure 1 can be indirectly connected to the boss 223 through other components.

[0061] In this optional embodiment, since the unlocking structure 1 can be connected to the boss 223 through the through-hole 2121, and the boss 223 is connected to the rod body 221, while the locking pin 222 is located at the end of the rod body 221, when the locking pin 222 is in the extended position, if the driving device 23 and the transmission mechanism 24 malfunction, the operator can apply a pulling force to the unlocking structure 1. At this time, the pulling force is transmitted to the rod body 221 through the boss 223 via the unlocking structure 1, causing the rod body 221 to drive the locking pin 222 to perform a manual return action relative to the housing 21 (i.e., the rod body 221 moves along...). Figure 4 (Reverse movement of the Y-axis in the coordinate system) so that the locking pin 222 disengages from the lock hole of the locked part, thereby unlocking the locked part and allowing the operator to open the locked part smoothly.

[0062] Optionally, combined Figure 2 , Figure 5 , Figure 6 and Figure 9 As shown, the actuator 2 also includes a dust cap 25, which is fixed to the housing 21 at the position corresponding to the strip hole 2121. The unlocking structure 1 is connected to the dust cap 25. The dust cap 25 is a housing structure with one end open towards the housing 21 and a first cavity 251 inside. The part of the boss 223 that passes through the strip hole 2121 is located inside the first cavity 251. The boss 223 is used to move along the first direction inside the first cavity 251.

[0063] Specifically, the dust cap 25 is disposed at the strip hole 2121, and the first cavity 251 of the dust cap 25 is connected to the second cavity of the housing 21 through the strip hole 2121, so that the boss 223 remains inside the first cavity 251 of the dust cap 25 after passing through the strip hole 2121.

[0064] The unlocking structure 1 can be indirectly connected to the boss 223 via the dust cap 25.

[0065] The dust cap 25 is fixedly connected to the cover 212 of the housing 21. For example, the dust cap 25 and the cover 212 can be formed into an integrated structure by injection molding, bonding, riveting, etc.

[0066] Along the first direction (i.e.) Figure 5 In the Y-axis direction of the coordinate system, the size of the first cavity 251 of the dust cap 25 is greater than the size of the boss 223, and the size of the first cavity 251 of the dust cap 25 can be greater than or equal to the size of the strip hole 2121.

[0067] In this optional embodiment, the dust cap 25 is fixed to the housing 21 at the position corresponding to the slotted hole 2121, so as to seal the slotted hole 2121 on the cover 212 of the housing 21 through the dust cap 25, so as to prevent external impurities from entering the second cavity of the housing 21 through the slotted hole 2121. Since the unlocking structure 1 is connected to the dust cap 25, and the part of the boss 223 that penetrates the slotted hole 2121 is located in the first cavity 251 of the dust cap 25, the operator applies pressure along the unlocking structure 1. Figure 2 The pulling force in the opposite direction of the Y-axis in the coordinate system can be transmitted to the boss 223 on the rod body 221 via the dust cap 25. The dust cap 25 can deform under the pulling force of the unlocking structure 1. This pulling force can drive the boss 223 and the rod body 221 along... Figure 2 The Y-axis in the coordinate system is manually returned to its original position relative to the housing 21, so that the locking pin 222 on the rod body 221 is disengaged from the locking hole of the locked part, which facilitates the smooth opening of the locked part.

[0068] Optionally, combined Figures 7 to 8 As shown, the unlocking structure 1 includes a pull wire portion 11 and a connecting portion 12. The connecting portion 12 is connected to the end of the pull wire portion 11. The connecting portion 12 is provided with a connecting hole 121. The connecting hole 121 of the connecting portion 12 is sleeved on the dust cap 25. The dust cap 25 is used to deform under the pulling force transmitted to the connecting portion 12, so as to drive the boss 223 to perform a manual return action.

[0069] Specifically, the unlocking structure 1 can adopt the following structure, for example, the unlocking structure 1 includes a pull wire part 11 and a connecting part 12. One end of the pull wire part 11 is connected to the connecting part 12, and the other end of the pull wire part 11 may have a pull ring. The operator can use the pull ring of the pull wire part 11 to help apply pulling force to the connecting part 12.

[0070] The connecting part 12 can be connected to the dust cap 25 in the following ways: for example, the connecting part 12 is provided with a connecting hole 121, the size of which can be greater than or equal to the size of the dust cap 25, thereby helping the connecting hole 121 of the connecting part 12 to be smoothly fitted onto the dust cap 25.

[0071] The dust cap 25 can be made of flexible materials such as rubber or silicone, so that the dust cap 25 can deform under the pulling force of the operator and return to its original shape when the pulling force of the operator is removed.

[0072] In this optional embodiment, one end of the pull cable 11 is connected to the connecting part 12, and the connecting hole 121 of the connecting part 12 is fitted onto the dust cap 25. When the locking pin 222 is in the extended position, if the driving device 23 or the transmission mechanism 24 malfunctions, the operator's finger can be inserted into the pull ring of the pull cable 11 to apply force along the pull. Figure 2 A tensile force acting in the opposite direction along the Y-axis in the coordinate system is transmitted to the dust cap 25 via the connecting part 12, causing the dust cap 25 to deform. As the tensile force increases, the deformation of the dust cap 25 causes the boss 223 to move within the slot 2121 and the first cavity 251 of the housing 21. The locking pin 222 can move along the rod body 221. Figure 2 The Y-axis in the coordinate system moves in the opposite direction to achieve the manual return action of the locking pin 222.

[0073] Optionally, combined Figure 6 , Figure 7 , Figure 9 and Figure 10 As shown, the unlocking structure 1 further includes an extension 13, the extension 13 is provided at the end of the connecting part 12 along the second direction, the housing 21 includes a guide part 214, the guide part 214 and the dust cap 25 are arranged at intervals along the second direction, the extension 13 is slidably connected to the guide part 214, and the second direction is perpendicular to the first direction.

[0074] Specifically, if the first direction is the extension direction of the moving rod 22, and the second direction is perpendicular to the first direction in the horizontal direction, that is, the second direction can be parallel to... Figure 6 The X-axis is parallel in the coordinate system.

[0075] An extension 13 may be provided at least one end of the connecting portion 12 along the second direction. The extension 13 and the connecting portion 12 may be configured as an integral structure. The extension 13 may be along... Figure 6 A plate-like structure extending along the Y-axis in a coordinate system.

[0076] A guide portion 214 may be provided on the cover 212 of the housing 21, and the guide portion 214 and the dust cap 25 are spaced apart along the second direction; when the connecting hole 121 of the connecting portion 12 is fitted onto the dust cap 25, the extension portion 13 on the connecting portion 12 may be located below the guide portion 214 on the cover 212.

[0077] In this optional embodiment, since the connecting hole 121 of the connecting part 12 is fitted onto the dust cap 25, when the operator applies a pulling force to the pull cable part 11, the extension part 13 can slide and connect with the guide part 214. This not only ensures the orientation of the part of the connecting part 12 that drives the dust cap 25 and the boss 223 to move in the first direction, preventing the connecting part 12 and the dust cap 25 from shifting in the second direction, but also reduces the loss of the pulling force acting on the boss 223, so that the manual return action of the locking pin 222 can be achieved with a smaller pulling force. Moreover, the extension part 13 of the unlocking structure 1 can be located below the guide part 214, so that the guide part 214 can move in the vertical direction ( Figure 6The extension 13 is limited in the Z-axis direction of the coordinate system to reduce the probability of the connecting part 12 detaching from the dust cap 25, thereby increasing the connection stability between the unlocking structure 1 and the dust cap 25.

[0078] Optionally, combined Figure 6 and Figure 8 As shown, the housing 21 also includes a limiting part 213, the pull wire part 11 passes through the limiting part 213, and the limiting part 213 and the dust cap 25 are spaced apart along the first direction.

[0079] Specifically, a limiting part 213 is provided on the cover 212 of the housing 21, and the limiting part 213 and the dust cap 25 can be spaced apart along the first direction. The limiting part 213 can be a block structure, rod structure, plate structure, etc. with a channel, which is used for the pull wire part 11 of the unlocking structure 1 to pass through; the channel can be a through hole structure, or it can be a gap structure between at least two spaced block structures.

[0080] In this optional embodiment, since a limiting part 213 is provided on the housing 21 and the limiting part 213 and the dust cap 25 are spaced apart along the first direction, when the operator applies a pulling force to the pull cable part 11, the limiting part 213 can ensure that the pulling force direction of the pull cable part 11 and the dust cap 25 are always on the same straight line, so that the pulling force on the pull cable part 11 can be completely transmitted to the boss 223 through the dust cap 25, reducing the loss of pulling force and further ensuring the orientation of the boss 223 in the slot 2121.

[0081] Optionally, combined Figure 5 and Figure 9 As shown, the dust cap 25 protrudes from the surface of the housing 21.

[0082] Specifically, the dust cap 25 protruding from the surface of the housing 21 can be understood as extending along... Figure 5 In the positive Z-axis direction of the coordinate system, the top surface of the dust cap 25 should be higher than the top surface of the housing 21 to ensure that the dust cap 25 has a certain height.

[0083] In this optional embodiment, when the connecting part 12 is fitted onto the dust cap 25, and the operator applies a pulling force to the connecting part 12 through the pull wire part 11, since the dust cap 25 protrudes from the surface of the housing 21, it is equivalent to increasing its deformation by increasing the height of the dust cap 25. Accordingly, it ensures that the moving rod 22 has sufficient manual return stroke, and accordingly ensures that the locking pin can completely disengage from the lock hole of the locked part. Furthermore, the dust cap 25 with a certain height also facilitates quick assembly and disassembly with the connecting part 12 of the unlocking structure 1.

[0084] Optionally, combined Figure 2 , Figure 9 and Figure 11As shown, the housing 21 has a through hole for the rod body 221 to pass through; the movable rod 22 also includes a limiting member 224, which is disposed on the rod body 221 and located outside the housing 21, and the size of the movable rod 22 at the limiting member 224 is larger than the size of the through hole.

[0085] Specifically, the perforation in the housing 21 can be formed in the following manner: for example, the cover 212 of the housing 21 has a first arc-shaped hole, and the bottom shell 211 of the housing 21 has a second arc-shaped hole. After the cover 212 and the bottom shell 211 are assembled, the first arc-shaped hole and the second arc-shaped hole surround each other to form the perforation. This perforation is used for the rod body 221 to pass through the housing for extension or retraction. The shape of the perforation can match the formation of the rod body. For example, if the rod body is a polygonal prism structure, the perforation can be a polygonal hole; if the rod body is a cylindrical structure, the perforation can be a circular hole or a hole of other shapes.

[0086] A limiting member 224 can be provided at a position on the rod body 221 near the locking pin 222. The limiting member 224 can adopt the following structures, such as a ring structure, block structure, rod structure, etc., provided on the rod body 221. The limiting member 224 can be coaxially or eccentrically arranged relative to the rod body 221. As long as the size of the limiting member 224 is larger than the size of the through hole, any setting method of the limiting member 224 is applicable to this technical solution, and no specific limitation is made here.

[0087] The limiting member 224 is always located on the outside of the housing 21.

[0088] In this optional embodiment, since the size of the moving rod 22 at the limiting member 224 is larger than the size of the through hole, the limiting member 224 limits the position of the locking pin 222 of the moving rod 22 driven by the unlocking structure 1 to prevent the moving rod 22 from moving beyond its travel and damaging the transmission mechanism 24 and the driving component 23 when the operator's pulling force is too great. This ensures the smooth manual return of the locking pin 222 while ensuring the safety of the transmission mechanism 24 and the driving component 23.

[0089] Optionally, combined Figure 3 and Figure 11 As shown, the transmission mechanism 24 includes a gear assembly 241 and a rotating shaft 242. The driving device 23 is connected to the gear assembly 241. One end of the rotating shaft 242 is fixedly connected to the gear assembly 241, and the other end of the rotating shaft 242 away from the gear assembly 241 is threadedly connected to the rod body 221.

[0090] The movable rod 22 further includes a limiting rod structure 225, which extends along a third direction and is connected to the rod body 221. The inner wall of the housing 21 is provided with a limiting groove 2111, which extends along the first direction. A portion of the limiting rod structure 225 is slidably connected to the limiting groove 2111. The limiting rod structure 225 is used to limit the rotation of the rod body 221. The third direction is perpendicular to the first direction.

[0091] Specifically, the driving device 23 can be a rotary motor, and the gear assembly 241 is used to transmit the rotational force of the driving device 23 to the rotating shaft 242 to drive the rotating shaft 242 to rotate.

[0092] The gear assembly 241 may adopt the following structure, for example, the gear assembly 241 includes a main gear 2411 and a driven gear 2412, the motor shaft of the driving device 23 is connected to the main gear 2411, the main gear 2411 meshes with the driven gear 2412, the driven gear 2412 is interference-fitted with the rotating shaft 242, and the driving device 23 can drive the main gear 2411 to rotate, so as to drive the driven gear 2412 and the rotating shaft 242 to rotate synchronously.

[0093] The end of the rotating shaft 242 away from the gear assembly 241 is threadedly connected to the end of the rod body 221 away from the locking pin 222.

[0094] The third direction can be combined with Figure 11 The Z-axis direction is parallel in the coordinate system; the limiting rod structure 225 can be extended along a third direction, i.e., vertically, and a limiting groove 2111 is provided on the inner bottom wall of the bottom shell 211 of the housing 21. At least a part of the limiting rod structure 225 is located in the limiting groove 2111 and is used to slide in the limiting groove 2111 along the first direction.

[0095] In this optional embodiment, when the driving device 23 and the transmission mechanism 24 are working normally, the driving device 23 can drive the gear assembly 241 and the rotating shaft 242 to rotate. Since the rod body 221 is threadedly connected to the rotating shaft 242, and the limiting rod structure 225 provided on the rod body 221 is slidably connected to the limiting groove 2111 of the bottom shell 211, the limiting rod structure 225 of the moving rod 22 cooperates with the limiting groove 2111 to convert the rotational force transmitted by the rotating shaft 242 into the extension or automatic return action of the moving rod 22 in the first direction.

[0096] When the locking pin 222 is in the extended position, if the driving mechanism 23 or the transmission mechanism 24 malfunctions, the operator can apply a pulling force to the connecting part 12 via the dust cap 25 through the pull cable 11. At this time, under the action of the pulling force, the boss 223 drives the rod body 221 and the locking pin 222 along... Figure 2The Y-axis moves in the opposite direction in the coordinate system. Since the rod body 221 is threadedly connected to the rotating shaft 242, the rod body 221 can convert the linear tension of the unlocking structure 1 along the first direction into the rotational force of the rotating shaft 242. At this time, the rotation direction of the rotating shaft 242, the gear assembly 241 and the driving device 23 is the same as the rotation direction during the manual return action and the automatic return action, so as to realize the manual return action of the locking pin 222.

[0097] Optionally, the rod body 221 can be threadedly connected to the rotating shaft 242 in the following manner, in combination with... Figures 12 to 14 As shown, the rod body 221 is a sleeve structure with an internal thread 2211, and the end of the rotating shaft 242 away from the gear assembly 241 is provided with an external thread 2421. The rod body 221 is sleeved on the rotating shaft 242, and the internal thread 2211 of the rod body 221 is threadedly connected to the external thread 2421 of the rotating shaft 242.

[0098] Specifically, the rod body 221 can be sleeved on the outside of the end of the rotating shaft 242 away from the gear assembly 241. Along the first direction, the length of the internal thread 2211 of the rod body 221 is greater than or equal to the length of the external thread 2421 of the rotating shaft 242.

[0099] In this optional embodiment, since the rod body 221 is a sleeve structure with an internal thread 2211, and the internal thread 2211 of the rod body 221 is connected to the external thread 2421 of the rotating shaft 242 by means of threads, the two can cooperate to convert the rotational force of the rotating shaft 242 into the extension and automatic return action of the rod body 221 relative to the housing 21 when the driving device 23 and the transmission mechanism 24 are working normally; or, when the driving device 23 and the transmission mechanism 24 malfunction, the rod body 221 converts the linear tension from the unlocking structure 1 into the rotational force of the rotating shaft 242 to realize the manual return action of the moving rod 22.
