Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to an object support device and a medical imaging system. Background Technology

[0002] In existing medical imaging systems, object support devices are typically used to support the object being examined (such as a patient) during the examination and to accurately position it in the working position of the imaging equipment. With the development of composite imaging technologies, such as PET-CT (electron emission computed tomography-computed tomography) and PET-MR (electron emission computed tomography-magnetic resonance imaging), multimodal imaging systems are becoming increasingly common, significantly increasing the distance the object can move between different imaging modalities.

[0003] To meet the spatial and positioning requirements of cross-modal imaging processes, the object support device is usually installed as a whole on a transport table. The support device can be moved a long distance within the imaging scanning chamber by moving the transport table. After the object support device moves to the target position, it locks with the transport table to perform the corresponding imaging scan. Utility Model Content

[0004] The inventors discovered that in the prior art, the object support device is locked to the transport platform by a pedal set on one side of the transport platform and a locking structure driven by the pedal. However, the pedal may be accidentally stepped on during actual use, causing the pedal to be stepped on incorrectly before the object support device reaches the target position. This not only prevents the object support device from being locked to the transport platform, but also easily damages the locking structure.

[0005] To address at least one of the aforementioned technical problems, embodiments of this application provide an object support device and a medical imaging system. In the object support device of this application, the locking component includes an anti-mislocking part. This anti-mislocking part prevents the driving component from initiating the locking operation of the locking component before reaching a predetermined position, thus avoiding damage to components due to collisions and improving safety.

[0006] This application provides an object support device for supporting an object during inspection. The object support device includes:

[0007] The base is fixedly installed in the inspection chamber where the object support device is located;

[0008] A bed board for movably supporting the object to be inspected along the longitudinal direction of the base;

[0009] A drive assembly is mounted on the upper side of the bed board and can drive the bed board to rise and fall; the lower side of the drive assembly is mounted on the base and can move along the longitudinal direction of the base.

[0010] The locking assembly includes a foot pedal, a locking pin, an anti-mislocking part, and a pin hole disposed on the drive assembly. The foot pedal drives the locking pin to move into or out of the pin hole. When the locking pin is out of the pin hole, the anti-mislocking part engages the locking pin to restrict its movement. When triggered by the drive assembly, the anti-mislocking part releases from the locking pin to allow the locking pin to move into the pin hole.

[0011] In some embodiments, the anti-mislocking part includes a first arm capable of locking the locking pin and a second arm capable of being pushed by the drive assembly;

[0012] When the drive assembly moves along the longitudinal direction of the base and does not contact the second arm, the first end of the first arm is engaged in the locking pin to restrict the movement of the locking pin; when the drive assembly triggers and pushes the second arm to rotate by a first angle, the first arm moves out of the locking pin through the rotation of the pivot on the locking pin base, releasing the locking pin to allow the locking pin to move into the pin hole.

[0013] In some embodiments, the first arm and the second arm form a predetermined second angle, and the first end of the second arm includes a shaft portion extending into one side of the base and capable of contacting the drive assembly.

[0014] A through hole is provided at the junction of the second end of the first arm and the second end of the second arm, and the through hole accommodates the rotating shaft.

[0015] In some embodiments, the locking pin is provided with a groove, and at least a portion of the first end of the first arm is engaged in the groove to restrict the movement of the locking pin;

[0016] When the drive component triggers and pushes the second arm to rotate the first angle, at least a portion of the first end of the first arm leaves the groove to unlock the locking pin.

[0017] In some embodiments, a torsion spring is provided on the through hole.

[0018] When the drive assembly triggers and pushes the second arm to rotate at the first angle, the second arm rotates in the first rotation direction via the pivot, and the torsion spring is compressed.

[0019] When the drive assembly leaves the second arm, the second arm rotates in a second rotation direction opposite to the first rotation direction under the action of the torsion spring, and the torsion spring is released.

[0020] In some embodiments, the anti-mislocking part includes a triggering component installed inside the base, a connecting component connected to the triggering component, and a blocking component connected to the connecting component;

[0021] Wherein, when the drive assembly moves along the longitudinal direction of the base and does not contact the anti-mislocking part, the blocking member blocks the locking pin;

[0022] When the anti-mislocking part is triggered by the drive component, at least a portion of the triggering component is displaced and drives the blocking component to move via the connecting component, thereby unlocking the locking pin.

[0023] In some embodiments, the connecting component includes an inner core cable and a guide sleeve, one end of the inner core cable being connected to the triggering component and the other end of the inner core cable being connected to the blocking component; the inner core cable passes through the guide sleeve at the bottom of the base and is connected to the blocking component.

[0024] In some embodiments, when the drive assembly moves along the longitudinal direction of the base and does not contact the anti-mislocking part, the pedal of the foot pedal cannot be depressed to restrict the movement of the locking pin;

[0025] When the anti-mislocking part is triggered by the drive component, the pedal of the foot pedal can be depressed to unlock the locking pin, allowing the locking pin to move into the pin hole.

[0026] In some embodiments, the foot pedal further includes a transition component and a sensor pin disposed in the pin hole. The pedal of the foot pedal is connected to the transition component. When the locking pin is unlocked and the pedal is stepped on, the transition component rotates the locking pin inward toward the base and contacts the sensor pin. The sensor pin contacts a sensor disposed outside the pin hole. The sensor acquires and reports the position information of the drive assembly.

[0027] In some embodiments, the anti-mislocking unit includes: a position sensor for detecting whether the drive assembly has reached the locking position or for detecting whether the locking pin and the pin hole are aligned; and an electromagnetic locking unit fixed to or mounted on the locking pin base for controlling the locking and releasing of the locking pin.

[0028] In some embodiments, the anti-mislocking unit further includes a controller module, which is used to receive signals sent by the position sensor and drive the electromagnetic locking unit.

[0029] This application provides a medical imaging system, which includes: an imaging device and an object support device as described in any of the foregoing embodiments.

[0030] One of the beneficial effects of the embodiments of this application is that: in the object support device, the locking component includes an anti-mislocking part. Through the anti-mislocking part, it is possible to prevent the driving component from starting the locking operation of the locking component before reaching the predetermined position, thereby avoiding damage to the components due to collision and improving safety.

[0052] The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0053] This application provides an object support device.

[0054] Figure 1 This is a schematic diagram of an object support device according to an embodiment of this application. Figure 1 As shown, the object support device 100 includes:

[0055] Base 101, which is fixedly installed in the inspection chamber where the object support device is located; bed board 102, which is used along the longitudinal direction of base 101 ( Figure 1 The inspection object can be movably carried in the X direction; the drive assembly 103 is mounted on the upper side of the bed board 102 and can drive the bed board 102 to rise and fall. Figure 1 (in the Y direction), the lower side of the drive assembly 103 is mounted to the base 101, and can be mounted along the longitudinal direction of the base 101 (in the Y direction). Figure 1 (Move in the X direction); Lock component 104.

[0056] For example, the base 101 includes two opposing support rails 1011, which are fixedly installed on the floor of the inspection chamber where the object support device 100 is located, and the lower side of the drive assembly 103 is respectively installed on the support rails 1011, and the drive assembly 103 is capable of carrying the inspection object along the longitudinal direction of the support rails 1011. Figure 1 The object is moved in the X direction, allowing it to be transported to the location to be inspected.

[0057] For example, the bed board 102 carries the object to be inspected; for example, the upper side of the drive assembly 103 is mounted to the bed board 102 and the drive assembly 103 is capable of driving the bed board 102 along... Figure 1 The lifting and lowering in the Y direction, as shown, allows the object to be transported to the height to be inspected. The locking component 104 of the object support device 100 will be further described below.

[0058] Figure 2This is an embodiment of the present application. Figure 1 A schematic diagram of a locking component 104 in the middle.

[0059] like Figure 2 As shown, the locking component 104 includes components disposed on the base 101 ( Figure 2 The drive assembly 103 includes a foot pedal 21 (not shown), a locking pin 22, an anti-mislocking part 23, and a pin hole 24. The foot pedal 21 drives the locking pin 22 to move into or out of the pin hole 24. The anti-mislocking part 23 engages the locking pin 22 when it is out of the pin hole 24 to restrict its movement. When triggered by the drive assembly 103, the anti-mislocking part 23 disengages from the locking pin 22 to allow it to move into the pin hole 24. For example, the drive assembly 103 is provided with a triggering structure (…). Figure 2 (Unmarked), for example, the trigger structure is a structure provided on the drive assembly 103 that matches the locking pin base 25 when the pin hole 24 engages with the locking pin 22. For example, the trigger structure is a trigger block or locking block provided on the drive assembly 103, and the trigger block or locking block is provided with a pin hole 24.

[0060] In some embodiments, such as Figure 2 As shown, the locking assembly 104 also includes a locking pin base 25 for receiving the locking pin 22. When the locking pin 22 on the locking pin base 25 is not aligned with the pin hole 24 on the drive assembly 103 (or when the pin hole 24 on the drive assembly 103 has not reached the predetermined position), the anti-locking part 23 engages the locking pin 22 to restrict its movement. When the locking pin 22 on the locking pin base 25 is aligned with the pin hole 24 on the drive assembly 103 (or when the pin hole 24 on the drive assembly 103 has reached the predetermined position), the anti-locking part 23 releases the locking pin 22 to allow its movement.

[0061] Therefore, by using the anti-mislocking unit, it is possible to prevent the drive component from starting the locking operation of the component before reaching the predetermined position, thereby avoiding damage to the component due to collision and improving safety.

[0062] Figure 3 This is an embodiment of the present application. Figure 2 A schematic diagram of one component of the anti-mislocking mechanism. (See diagram below.) Figure 3 As shown, the anti-locking part 23 includes a first arm 31 (also called a locking part), a second arm 32 (also called a driving part), and a through hole 33 at the junction of the first arm and the second arm. A torsion spring 34 can be installed in the through hole 33. The first arm 31 includes a first end 311 and a second end 312. The second arm 32 includes a first end 321, a shaft 322, and a second end 323. The first arm 31 of the anti-locking part 23 can lock the locking pin 22, and the second arm 32 of the anti-locking part 23 can be pushed by the driving assembly 103.

[0063] In some embodiments, such as Figure 3 As shown, the first arm 31 and the second arm 32 are at a predetermined second angle (e.g., 90 degrees, but not limited thereto), and the first end portion 321 of the second arm 32 includes a shaft portion 322 extending into one side of the locking pin base 25 and capable of contacting the drive assembly 103. A through hole 33 is provided at the junction of the second end portion 312 of the first arm 31 and the second end portion 323 of the second arm 32, which can accommodate the rotating shaft 251 on the locking pin base 25. Figure 3 Not shown, please refer to Figure 4 ).

[0064] Figure 4 This is a schematic diagram of the anti-mislocking unit in an embodiment of this application.

[0065] Figure 4 The anti-mislocking part 23 and Figure 3 Similarly, for a clearer example, in Figure 4 The specific components of the anti-mislocking part 23 are no longer marked.

[0066] The following combination Figure 3 and Figure 4 Further explanation is provided for the anti-mislocking unit 23. For example... Figure 3 as well as Figure 4 As shown, along the base 101, the drive assembly 103... Figure 4 When the first arm 31 moves along its longitudinal direction (not shown) and does not contact the second arm 32, the first end 311 of the first arm 31 engages within the locking pin 22 to restrict the movement of the locking pin 22. Figure 4 (Not shown); the drive assembly 103 triggers and pushes the second arm 32 to rotate (e.g., the direction of rotation of the second arm 32 is as shown). Figure 3 At the first angle (e.g., 60 degrees, but not limited thereto), the first arm 31 moves out of the inside of the locking pin 22 via the rotation of the pivot 251 on the locking pin base 25, unlocking the locking pin 22 to allow the locking pin 22 to move into the pin hole 24.

[0067] Therefore, by rotating the anti-mislocking part, locking / unlocking the lock pin can be made easier and the accuracy of the locking position can be guaranteed.

[0068] In some embodiments, such as Figure 3 and Figure 4 As shown, a groove 221 is provided on the locking pin 22, and at least a portion of the first end 311 of the first arm 31 is engaged in the groove 221 to restrict the movement of the locking pin 22; when the drive assembly 103 triggers and pushes the second arm 32 to rotate by a first angle, at least a portion of the first end 311 of the first arm 31 leaves the groove 221 to unlock the locking pin 22.

[0069] like Figure 4As shown, the anti-locking unit 23 can be connected to the rotating shaft 251 in the first rotation direction (e.g., Figure 4 The clockwise direction in the middle, that is... Figure 4 The anti-mislocking part 23 can rotate in the direction indicated by the dashed arrow, or it can rotate in the second rotation direction opposite to the first rotation direction via the rotating shaft 251.

[0070] In some embodiments, such as Figure 3 and Figure 4 As shown, a torsion spring 34 is provided in the through hole 33. When the drive assembly 103 pushes the shaft 322 of the second arm 32 to rotate by a first angle, the second arm 32 rotates in the first rotation direction through the rotating shaft 251, and the torsion spring 34 is pressed. When the drive assembly 103 leaves the shaft 322 of the second arm 32, the second arm 32 rotates in the second rotation direction opposite to the first rotation direction under the action of the torsion spring 34, and the torsion spring 34 is released.

[0071] For example, the torsion spring 34 has 162 degrees of freedom (±10 degrees), a total of 3.05 coils, a spring body length of 4.05 mm, a calculated torque of 34.73 N-mm when twisted to 146 degrees, and a calculated torque of 89 N-mm when twisted to 121 degrees. The above parameters are for illustrative purposes only and this application is not limited thereto.

[0072] Therefore, by setting a torsion spring inside the through hole, the anti-locking part can automatically rebound to lock the locking pin, and the locking / unlocking of the locking pin can be achieved with a simple structure.

[0073] The following diagrams further illustrate how the locking component works. Figure 5 This is an embodiment of the present application. Figure 1 The diagram shown illustrates one state of the locking component. Figure 6 This is an embodiment of the present application. Figure 1 Another schematic diagram of the locking component is shown. Figure 5 and Figure 6 Detailed examples of the various structures shown can be found in [link to relevant documentation]. Figures 1 to 4 This will not be repeated here.

[0074] like Figure 5 As shown, the drive component 103 can run along the longitudinal direction of the base 101. Figure 5 When the drive assembly 103 moves along the longitudinal direction of the base 101 and does not contact the second arm 32 of the anti-mislocking part 23, that is, when the drive assembly 103 has not reached the locking position, the first arm 31 (in the X direction) moves, and when the drive assembly 103 moves along the longitudinal direction of the base 101 and does not contact the second arm 32 of the anti-mislocking part 23, that is, when the drive assembly 103 has not reached the locking position, the first arm 31 (in the X direction) moves. Figure 5 The first end 311 (not shown) Figure 5 (Not shown) The latch is engaged with the locking pin 22 ( Figure 5(Not shown) The movement of the locking pin 22 is restricted. Even if the foot pedal 21 is stepped on at this time, the locking pin 22 will not move out. Therefore, the locking pin 22 will not come into contact with the drive assembly 103, which can avoid damage to the components caused by the collision and improve safety.

[0075] like Figure 6 As shown, when the drive assembly 103 moves along the longitudinal direction of the base 101 and triggers the second arm 32 to rotate by a first angle, that is, when the drive assembly 103 reaches the locked position, the first end 311 of the first arm 31 moves out from inside the locking pin 22 via the rotation of the pivot 251 on the locking pin base 25, thereby unlocking the locking pin 22, and at this time the foot pedal 21 ( Figure 6 (Not shown), the locking pin 22 can move into the pin hole 24 of the drive assembly 103 ( Figure 6 (Not shown) This allows the drive component to be locked in the locking position, improving locking accuracy.

[0076] The above describes some embodiments of this application. The following describes some other embodiments of this application.

[0077] For example, Figure 1 The locking component of the object support device 100 can also be a locking component 104'.

[0078] Figure 7A This is a schematic diagram of a component of the locking component 104' in an embodiment of this application; Figure 7B This is another perspective view of the locking component 104' in an embodiment of this application. Figure 7A and Figure 7B As shown, Figure 7A The locking assembly 104' shown also includes a foot pedal 21 disposed on the base 101 and a locking pin. Figure 7A and Figure 7B (Not shown), a pin hole provided in the drive assembly 103 ( Figure 7A and Figure 7B (Not shown), anti-mislocking part 70. For example, the locking pin and pin hole in the locking assembly 104' are... Figure 2 The locking pin 22 and pin hole 24 are the same, so they will not be described again here.

[0079] In some embodiments, combined with Figure 7A and Figure 7B The anti-locking unit 70 includes a triggering component 71 installed inside the base 101, a connecting component 72 connected to the triggering component 71, and a blocking component 73 connected to the connecting component 72; wherein, when the drive assembly 103 moves along the longitudinal direction of the base 101 ( Figure 7AWhen the anti-mislocking part 70 is not in contact with the X direction shown, the blocking member 73 blocks the locking pin 22; when the anti-mislocking part 70 is triggered by the driving component 103, at least a portion of the triggering member 71 is displaced and drives the blocking member 73 to move via the connecting member 72, so that the blocking member 73 unlocks the locking pin 22.

[0080] In some embodiments, 7A and Figure 7B The connecting component 72 includes a guide sleeve 721 and an inner core steel cable 722. One end of the inner core steel cable 722 is connected to the trigger component 71, and the other end of the inner core steel cable 722 is connected to the blocking component 73. The inner core steel cable 722 passes through the guide sleeve 721 at the bottom of the base 101 and is connected to the blocking component 73.

[0081] For example, the connecting component 72 is a push-pull cable assembly, which includes an inner core cable 722 and a guide jacket 721. For example, the inner core cable 722 is composed of multi-strand steel wire rope or a single strand of steel wire, possessing good tensile strength and flexibility, used to transmit push-pull force or control signals; the guide jacket 721 is composed of a metal braided tube, a plastic corrugated tube, or a nylon sleeve, possessing pressure resistance, wear resistance, and corrosion resistance to protect the inner core cable from external forces; for example, the connecting component 72 may also include end connectors (…). Figure 7A and Figure 7B (Not shown), the end connector may include a ball head, threaded joint, snap fastener, fixing seat, etc. For example, the end connector is disposed at both ends of the inner core steel cable 722 to connect the contact triggering component 71 and the blocking component 73; for example, the connecting component 72 may also include a guide structure ( Figure 7A and Figure 7B (Not shown), the guide structure has a low-friction material (such as a PTFE bushing) on ​​the inside of the guide sleeve 721 to ensure smooth sliding of the inner core cable 722. Thus, by pushing and pulling the cable assembly through the sliding of the inner core cable 722 in the guide sleeve 721, remote mechanical control or force transmission can be achieved to lock or unlock the locking pin 22 of the blocking component 73.

[0082] Therefore, the drive components can be locked or unlocked in confined spaces with a compact structure, and the connection component 72 of this application is simple to maintain and highly reliable.

[0083] The following describes the operation of the locking assembly 104' in conjunction with the specific structure of the triggering component 71 and the connecting component 72.

[0084] For example, one end of the trigger component 71 (e.g., Figure 7B The bottom end of the triggering component 71 shown is connected to one end of the steel wire rope 722, and the other end of the triggering component 71 (for example, Figure 7BThe tip of the trigger member 71 shown is pushed by a portion (driving part) of the drive assembly 103. The middle of the trigger member 71 is rotatably fixed and a torsion spring or other suitable spring provides a reset force to the trigger member 71, thus forming a lever structure. For example, a reset spring is provided in the middle of the trigger member 71, which pushes the trigger member 71 in a third rotational direction (e.g., when the drive assembly 103 moves along the longitudinal direction of the base 101 and contacts one end of the trigger member 71). Figure 7B When the drive assembly 103 rotates counterclockwise (in the direction of rotation), one end of the inner core steel cable 722 of the connecting component 72 is pulled, and the inner core steel cable 722 moves in the guide sleeve 721. The other end of the inner core steel cable 722 pulls the blocking component 73 to unlock the locking pin 22. When the drive assembly 103 moves along the longitudinal direction of the base 101 and separates from the trigger component 71, the trigger component 71, under the action of the return spring, rotates in a fourth rotation direction opposite to the third rotation direction (e.g., counterclockwise). Figure 7B Rotating clockwise in the middle pulls one end of the inner core steel cable 722 of the connecting component 72, the inner core steel cable 722 moves in the guide jacket 721 and is pulled back, and the other end of the inner core steel cable 722 pulls the blocking component 73 to lock the locking pin 22.

[0085] Therefore, by blocking the movement of the component and connecting the transmission of the component, an appropriate locking position can be selected even in confined spaces to achieve locking / unlocking of the locking pin.

[0086] In some embodiments, when the drive assembly 103 moves along the longitudinal direction of the base 101 and does not contact the anti-locking part 70, the pedal of the foot pedal 21 cannot be depressed to restrict the movement of the locking pin 22; when the anti-locking part 70 is triggered by the drive assembly 103, the pedal of the foot pedal 21 can be depressed to unlock the locking pin 22, allowing the locking pin 22 to move into the pin hole 24.

[0087] The following diagrams further illustrate how the locking component works.

Figure 7A Another state diagram of the locking component 104' in the middle. Figure 8A , Figure 8B and Figure 8C Detailed examples of the various structures shown can be found in [link to relevant documentation]. Figure 7A and Figure 7B This will not be repeated here.

[0089] Combination Figure 8A and Figure 8B As shown, the drive assembly 103 can move along the longitudinal direction of the base 101. When the drive assembly 103 moves along the longitudinal direction of the base 101 and does not contact the triggering member 71 of the anti-mislocking part 70, that is, when the drive assembly 103 has not reached the locked position, the triggering member 71 will not pull the displacement of the inner core steel cable 722 of the connecting member 72. For example, as Figure 8B As shown, the blocking pin 731 of the blocking member 73 will block the foot pedal 21. For example, the blocking pin 731 can prevent the transition member 90 of the foot pedal 21 (see transition member 90). Figure 9 The foot pedal (specific structure) rotates, so even if the foot pedal 21 is stepped on at this time, the locking pin 22 will not move out. Therefore, the locking pin 22 will not contact the drive assembly 103, thereby preventing misoperation, avoiding damage to components caused by collision, and improving safety.

[0090] like Figure 8C As shown, at one end of the drive assembly 103 that contacts the trigger component 71, along the third rotational direction (e.g., Figure 8C When the third rotation direction is reversed (counterclockwise), the other end of the triggering component 71 rotates in a fourth rotation direction opposite to the third rotation direction (e.g., ...). Figure 8C The inner core steel cable 722 of the connecting component 72 is displaced by rotating clockwise. The inner core steel cable 722 is displaced through the flexible guide sleeve 721, so that the inner core steel cable 722 passes through the guide sleeve 721 at the bottom of the base 101 and connects with the blocking component 73. The blocking locking pin 731 of the blocking component 73 is retracted into the interior of the blocking component 73. Therefore, the transition component 90 of the foot pedal 21 can rotate and push the locking pin 22 into the pin hole 24. That is, when the foot pedal 21 is stepped on, the locking pin 22 can move into the pin hole 24 of the drive component 103, thereby locking the drive component 103 in the locking position and improving the accuracy of locking.

[0091] Figure 1 The object support device 100 shown includes a foot pedal 21. The foot pedal and related components will be described below.

[0092] Figure 9 This is a schematic diagram of one component of the foot pedal in an embodiment of this application.

[0093] In some embodiments, such as Figure 9As shown, the foot pedal 21 also includes a transition component 90 and a sensor pin 91 disposed in the pin hole 24. The pedal 92 of the foot pedal is connected to the transition component 90. When the locking pin 22 is unlocked and the pedal 92 is stepped on, the transition component 90 rotates the locking pin 22 toward the inside of the base 101 and contacts the sensor pin 91. The sensor pin 91 contacts the sensor 93 disposed outside the pin hole 24. The sensor 93 acquires and reports the position information of the drive assembly 103.

[0094] Therefore, by acquiring and reporting the position of the drive component 103 to the system through the sensor, it is proven that the locking pin 22 is in place. The position of the drive component 103 can be accurately obtained, avoiding damage to the component due to collision and further improving safety.

[0095] The above describes some embodiments of this application. The following describes some other embodiments of this application.

[0096] For example, Figure 1 The anti-mislocking part of the locking component of the object support device 100 may also include an anti-mislocking mechanism 1000. The anti-mislocking mechanism 1000 is an electronically triggered anti-mislocking mechanism that uses a position sensor and an electromagnetic driver to work together to determine whether the drive component has reached the predetermined locking position and automatically releases the locking pin when the conditions are met.

[0097] Figure 10 This is a schematic diagram of one component of the anti-mislocking mechanism 1000 according to an embodiment of this application.

[0098] In some embodiments, the anti-mislocking mechanism 1000 includes: a position sensor 1001 mounted on the drive assembly 103 or the locking pin base 25, the position sensor 1001 being used to detect whether the drive assembly 103 has reached the locking position (or target position) or whether the locking pin 22 and the pin hole 24 are aligned; and an electromagnetic locking unit 1002 fixed to the locking pin base 25 or mounted on the base 101, the electromagnetic locking unit 1002 being used to control the locking and releasing of the locking pin.

[0099] In some embodiments, the anti-mislocking mechanism 1000 further includes a controller module 1003, which is used to receive signals sent by the position sensor 1001 and drive the electromagnetic locking unit 1002.

[0100] For example, when the drive assembly 103 has not reached the locked position, the position sensor 1001 outputs an misalignment signal, and the controller module 1003 keeps the electromagnetic locking unit 1002 in a locked state, so that the locking pin cannot move; and only when the drive assembly 103 reaches the predetermined position (e.g., the locked position or the target position) or the locking pin 22 is aligned with the pin hole 24, and the position sensor 1001 outputs an alignment signal, does the controller module 1003 drive the electromagnetic locking unit 1002 to release the locking pin 22, allowing the locking pin 22 to enter the pin hole 24 to complete the locking operation.

[0101] This avoids the problem of premature extension of the locking pin caused by accidental mechanical stepping, thus improving the automation and safety of the system.

[0102] It is worth noting that the above appendix Figures 1 to 10 The embodiments of this application have only been illustrated schematically, and the application is not limited thereto.
