[0045] Figure 2 For the embodiment of the application, the lock hook 220 is in the locking position, and the locking piece 230 is in the first position, the partial structure diagram of the lock 200; Figure 3 For the embodiment of the application, the lock hook 220 is in the unlocking position, and the locking piece 230 is in the second position, the partial structure diagram of the lock 200; Figure 4 For the structure diagram of the driving piece 242 and the force receiving part 231 of the embodiment of the application; Figure 5 For the structure diagram of the driving piece 242 of the embodiment of the application.

[0046] Please refer to Figure 2 , Figure 3 and Figure 4The lock 200 of the embodiment comprises a housing 210, a lock hook 220, a locking member 230 and a driving assembly 240. The lock hook 220 and the locking member 230 are rotatably arranged in the housing 210. The lock hook 220 has a locking position for cooperating with the lock catch 120 and an unlocking position for separating from the lock catch 120. The locking member 230 has a first position for locking the lock hook 220 in the locking position and a second position for unlocking the lock hook 220 in the locking position. The driving assembly 240 is used for driving the locking member 230 to move from the first position to the second position. The driving assembly 240 comprises a motor 241 and a driving member 242. The driving member 242 is in transmission connection with an output shaft 249 (as shown in FIG. 1) of the motor 241. The driving member 242 comprises at least one driving part 243 with a helical surface 244. The locking member 230 has a force receiving part 231. In the state that the output shaft 249 of the motor 241 drives the driving member 242 to rotate, the helical surface 244 can cooperate with the force receiving part 231 to drive the locking member 230 to move from the first position to the second position. Specifically, the helical surface 244 spirally rises around the rotation axis of the driving member 242. The helical surface 244 comprises a highest end and a lowest end. The highest end and the lowest end have a displacement difference along the direction of the rotation axis of the driving member 242. When the driving member 242 rotates, the contact position between the helical surface 244 and the force receiving part 231 moves from the lowest end of the helical surface 244 to the highest end of the helical surface 244, thereby pushing the locking member 230 to move from the first position to the second position. Figure 8 When the box door 110 closes the opening 101, the lock hook 220 moves to the locking position to cooperate with the lock catch 120, and the locking member 230 moves to the first position to lock the lock hook 220 in the locking position. In this way, the lock hook 220 of the lock 200 can reliably cooperate with the lock catch 120 to reliably lock the box door 110 in the position of closing the opening 101. When it is needed to open the opening 101 by the box door 110, the output shaft 249 of the motor 241 drives the driving member 242 to rotate. The helical surface 244 of the driving part 243 rotates synchronously with the driving member 242. The force receiving part 231 of the locking member 230 cooperates with the helical surface 244. Only by using the movement of the contact position between the rotating helical surface 244 and the force receiving part 231, the locking member 230 can be pushed to rotate to the second position, so as to unlock the locking member 230 to the lock hook 220. The unlocked lock hook 220 can move to the unlocking position and separate from the lock catch 120 to complete the unlocking. The lock 200 provided by the present application has simple and compact structure, which is conducive to miniaturization design.

[0047] When the box door 110 closes the opening 101, the lock hook 220 moves to the locking position to cooperate with the lock catch 120, and the locking member 230 moves to the first position to lock the lock hook 220 in the locking position. In this way, the lock hook 220 of the lock 200 can reliably cooperate with the lock catch 120 to reliably lock the box door 110 in the position of closing the opening 101. When it is needed to open the opening 101 by the box door 110, the output shaft 249 of the motor 241 drives the driving member 242 to rotate. The helical surface 244 of the driving part 243 rotates synchronously with the driving member 242. The force receiving part 231 of the locking member 230 cooperates with the helical surface 244. Only by using the movement of the contact position between the rotating helical surface 244 and the force receiving part 231, the locking member 230 can be pushed to rotate to the second position, so as to unlock the locking member 230 to the lock hook 220. The unlocked lock hook 220 can move to the unlocking position and separate from the lock catch 120 to complete the unlocking. The lock 200 provided by the present application has simple and compact structure, which is conducive to miniaturization design.

[0048] Please refer to Figure 5The driving member 242 further comprises a transition surface 281 and a limiting surface 282, one end of the transition surface 281 is connected with the highest end of the helical surface 244, the other end of the transition surface 281 is connected with the first end of the limiting surface 282, and the second end of the limiting surface 282 is connected with the lowest end of the helical surface 244; please refer to Figure 2 and Figure 3 The lock 200 of the embodiment further comprises a first elastic member 253, the first elastic member 253 is connected with the locking member 230, for making the locking member 230 always have a tendency to rotate to the first position, and when the locking member 230 is located at the first position, the stress part 231 abuts against the limiting surface 282. Specifically, when the contact position between the helical surface 244 and the stress part 231 moves to the highest end of the helical surface 244, the driving locking member 230 moves to the second position, and with the driving member 242 continuing to rotate, the stress part 231 is separated from the helical surface 244, and the stress part 231 of the locking member 230 can move along the transition surface 281 until abutting against the limiting surface 282 under the action of the first elastic member 253, and the locking member 230 resets to the first position. In this way, when the stress part 231 of the locking member 230 is separated from the helical surface 244, the first elastic member 253 is used to reset the locking member 230 to the first position to lock the lock hook 220 in the locked position, and the first elastic member 253 also ensures the reliability of the locking member 230 located at the first position, thereby making the lock hook 220 reliably locked in the locked position by the locking member 230, and ensuring the reliability of the cooperation between the lock hook 220 and the lock catch 120.

[0049] Further, the transition surface 281 and the limiting surface 282 are connected perpendicularly; in this way, it is beneficial to make the locking member 230 quickly move to the first position under the action of the first elastic member 253, and efficiently realize the locking of the position of the lock hook 220.

[0050] Further, the first end of the first elastic member 253 is connected with the locking member 230, and the second end of the first elastic member 253 is connected with the lock hook 220, under the elastic action of the first elastic member 253, the locking member 230 has a tendency to move to the first position, and the lock hook 220 has a tendency to rotate to the unlocked position. In this way, when the motor 241 drives the driving member 242 to rotate, the helical surface 244 cooperates with the stress part 231 to drive the locking member 230 to move to the second position, the lock hook 220 is unlocked in the locked position, and the lock hook 220 can move to the unlocked position under the action of the first elastic member 253, that is, the lock hook 220 can be separated from the lock catch 120, thereby using one part of the first elastic member 253 to realize the control of the movement of the two parts of the locking member 230 and the lock hook 220, simplifying the structure of the lock 200, and being more beneficial to miniaturization design.

[0051] Optionally, the first elastic member 253 is a tension spring; of course, in other embodiments, the first elastic member 253 can also be a torsion spring, an elastic rubber strip or other elastic member, which is not specifically limited here.

[0052] It should be noted that the connection mode of the two ends of the first elastic member 253 with the locking member 230 and the locking hook 220 can be selected as needed, and in the embodiment, the two ends of the first elastic member 253 are respectively hung with the locking member 230 and the locking hook 220. Of course, in other embodiments, the two ends of the first elastic member 253 can also be respectively welded with the locking member 230 and the locking hook 220, or connected with a bolt or other fastener, which is not specifically limited here.

[0053] Figure 6 FIG. 2 is a structural schematic diagram of the lock 200 in the embodiment of the present application in a first perspective view; please refer to Figure 2 、 Figure 3 and Figure 6 In the embodiment, the shell 210 is in a cuboid box structure, which is arranged on the periphery of the locking hook 220, the locking member 230, the driving assembly 240 and other structures, and plays a protective role on the locking hook 220, the locking member 230, the driving assembly 240 and other structures. The locking hook 220 of the embodiment is provided with a U-shaped accommodating groove 221, and the shell 210 is provided with a first opening 213; when the locking hook 220 cooperates with the lock catch 120, the lock catch 120 extends into the inside of the shell 210 through the first opening 213 and is located in the accommodating groove 221 of the locking hook 220; when the locking hook 220 rotates to the unlocking position, the groove wall of the accommodating groove 221 can drive the lock catch 120 to exit the shell 210 through the first opening 213. As shown in the case where the lock catch 120 of the embodiment is arranged on the box door 110 and the lock 200 is arranged on the box body 100, when the locking hook 220 is unlocked and the elastic action of the first elastic member 253 makes the locking hook 220 move to the unlocking position, the locking hook 220 can also make the box door 110 move relative to the box body 100 in the process of pushing the lock catch 120, so as to open the opening 101. After the box door 110 opens the opening 101, at this time, under the action of the first elastic member 253, as shown in FIG. 2, the locking hook 220 stays at the unlocking position, the locking member 230 stays at the second position, and the opening of the accommodating groove 221 of the locking hook 220 faces the first opening 213. When the box door 110 is rotated to close the opening 101, the lock catch 120 enters the accommodating groove 221 through the first opening 213 and the opening of the accommodating groove 221, and the power of rotating the box door 110 makes the lock catch 120 push the locking hook 220 to rotate against the elastic force of the first elastic member 253. When the box door 110 moves to the position of closing the opening 101, the locking hook 220 rotates to the locking position, and under the action of the first elastic member 253, the locking member 230 rotates to the first position, so as to lock the locking hook 220 at the locking position. Figure 3

[0054] Please continue to refer to Figure 2 and​Figure 3 The lock 200 of the embodiment further comprises a second elastic member 254, one end of the second elastic member 254 is connected with the lock hook 220, and the other end of the second elastic member 254 is connected with the shell 210; under the action of the second elastic member 254, the lock hook 220 always has a tendency to rotate to the unlocking position. The second elastic member 254 is arranged in the embodiment, so that when the motor 241 drives the driving member 242 to rotate the locking member 230 to the second position, the lock hook 220 can rotate to the unlocking position under the elastic action of the second elastic member 254, that is, the second elastic member 254 ensures the reliability of the unlocking of the lock 200.

[0055] The second elastic member 254 can be selected as required, and the second elastic member 254 of the embodiment is a plate spring. Of course, in other embodiments, the second elastic member 254 can also be a tension spring, a torsion spring, etc., which is not specifically limited here.

[0056] It should be noted that the connection mode of the two ends of the second elastic member 254 with the lock hook 220 and the shell 210 can be welding or connecting with bolts or other fasteners, which is not specifically limited here.

[0057] Please refer to Figure 2 and Figure 3 The lock 200 of the embodiment comprises a first rotating shaft 251, the locking member 230 is rotatably connected with the shell 210 through the first rotating shaft 251, and the axis of the first rotating shaft 251 is arranged at an angle with the rotating axis of the driving member 242. Further, the axis of the first rotating shaft 251 is perpendicular to the rotating axis of the driving member 242 in the embodiment. In this way, the size of the lock 200 in the direction of the axis of the first rotating shaft 251 can be reduced, which is more conducive to the miniaturization design of the lock 200.

[0058] It should be understood that in other embodiments, the angle between the axis of the first rotating shaft 251 and the rotating axis of the driving member 242 can be 88°, 91°, etc., which is not specifically limited here.

[0059] Please refer to Figure 2 and Figure 3 The lock 200 further comprises a second rotating shaft 252, the lock hook 220 is rotatably connected with the shell 210 through the second rotating shaft 252, and the first rotating shaft 251 and the second rotating shaft 252 are arranged in parallel. In this way, the size of the lock 200 in the direction of the axis of the first rotating shaft 251 can be effectively reduced, which is conducive to the miniaturization design of the lock 200.

[0060] Figure 7 It is a structural schematic view of the motor 241, the driving member 242 and the detection member 262 in the embodiment of the application.

[0061] Please refer to Figure 5 andFigure 7 The driving member 242 further comprises a sleeve 245 coaxially connected with the output shaft 249 of the motor 241; the driving part 243 is fixedly connected with the sleeve 245; in the state that the driving member 242 rotates, the helical surface 244 rotates around the output shaft 249 of the motor 241. Preferably, the sleeve 245 is directly sleeved on the output shaft 249 of the motor 241, and the sleeve 245 rotates synchronously when the output shaft 249 rotates, and the helical surface 244 of the driving part 243 rotates around the output shaft 249. In this way, the structure of the driving assembly 240 is more compact, and the size of the lock 200 in the direction of the rotation axis of the driving member 242 is smaller, i.e., the size of the lock 200 in the axial direction of the output shaft 249 of the motor 241 is smaller, which is more conducive to the miniaturization design of the lock 200.

[0062] Further, referring to Figure 5 The driving member 242 comprises a plurality of driving parts 243, the plurality of driving parts 243 are arranged at intervals in the circumferential direction of the sleeve 245, and the helical directions of the helical surfaces 244 of each driving part 243 are the same. Since the plurality of driving parts 243 are arranged at intervals in the circumferential direction of the sleeve 245, when the output shaft 249 of the motor 241 rotates by a set angle, the helical surface 244 of one driving part 243 can cooperate with the stress part 231 of the locking member 230, thereby driving the locking member 230 to rotate to the second position; when the output shaft 249 of the motor 241 rotates by one revolution, the helical surfaces 244 of the plurality of driving parts 243 can in turn drive the locking member 230 to rotate to the second position, i.e., the locking member 230 can be driven to rotate to the second position multiple times when the output shaft 249 of the motor 241 rotates by one revolution, thereby improving the unlocking efficiency of the lock 200 and reducing energy consumption.

[0063] It should be noted that when the driving member 242 comprises a plurality of driving parts 243, in the rotation direction of the driving member 242, the limiting surface 282 of each driving part 243 is connected with the lowest end of the helical surface 244 of the driving part 243 located downstream of the driving part 243. In multiple unlocking of the lock 200, the motor 241 always drives the driving member 242 to rotate in one direction, which is conducive to ensuring the service life of the motor 241.

[0064] Further, referring to Figure 5 The sleeve 245 comprises a bottom disc 246 and a guide column 247 coaxially connected, the outer diameter of the bottom disc 246 is greater than the outer diameter of the guide column 247, and the driving part 243 is arranged along the outer edge of the bottom disc 246. Since the driving part 243 is arranged along the outer edge of the bottom disc 246, when the output shaft 249 of the motor 241 drives the driving member 242 to rotate, the displacement of the helical surface 244 of the driving part 243 to the stress part 231 is large, thereby enabling the output shaft 249 of the motor 241 to reliably drive the locking member 230 to rotate to the second position by rotating a smaller angle, so as to reduce energy consumption.

[0065] The connection mode of the output shaft 249 of the motor 241 and the sleeve 245 can be selected as required. Please refer to Figure 5 The sleeve 245 of the embodiment is provided with a central hole 248, the central hole 248 penetrates the chassis 246 and the guide column 247, and the output shaft 249 of the motor 241 is fixedly inserted into the central hole 248. In this way, the output shaft 249 of the motor 241 is simultaneously inserted into the chassis 246 and the guide column 247, the contact area between the output shaft 249 of the motor 241 and the sleeve 245 is large, and the reliability of the motor 241 driving the driving member 242 is ensured.

[0066] Of course, in other embodiments, the output shaft 249 of the motor 241 can also be welded or riveted with the chassis 246, and the like, which is not specifically limited here.

[0067] Please refer to Figure 2 and Figure 3 The lock 200 of the embodiment further comprises a detection assembly 260, the detection assembly 260 comprises a first sensor 261 and a detection member 262, the detection member 262 is configured to be able to rotate synchronously with the driving member 242, and the first sensor 261 is arranged in the housing 210 and is used to cooperate or separate with the detection member 262 to detect whether the stress part 231 cooperates with the spiral surface 244. Specifically, when the detection member 262 rotates synchronously with the driving member 242 to cooperate with the first sensor 261, the stress part 231 cooperates with the spiral surface 244; when the detection member 262 rotates synchronously with the driving member 242 to separate from the first sensor 261, the stress part 231 separates from the spiral surface 244.

[0068] Figure 8 It is an exploded structural schematic view of the motor 241, the driving member 242 and the detection member 262 in the embodiment of the application.

[0069] Further, please refer to Figure 7 and Figure 8 The detection assembly 260 further comprises a support shaft 264, a first end of the support shaft 264 is fixedly connected with the driving member 242 in a coaxial manner, and a second end of the support shaft 264 is fixedly connected with the detection member 262; in the state that the stress part 231 cooperates with the spiral surface 244, the detection member 262 cooperates with the first sensor 261, and the first sensor 261 outputs a first signal; in the state that the stress part 231 separates from the spiral surface 244, the detection member 262 separates from the first sensor 261, and the first sensor 261 outputs a second signal. In this way, the position of the spiral surface 244 on the driving member 242 can be judged through the signal output by the first sensor 261, and the accuracy of the spiral surface 244 and the stress part 231 cooperating with each other to drive the locking member 230 to move to the second position can be ensured.

[0070] The storage cabinet 010 further comprises a controller (not shown in the figure) in communication connection with the first sensor 261 and in communication connection with the motor 241. When the first sensor 261 sends a first signal to the controller, the controller determines that the force receiving part 231 cooperates with the helical surface 244; when the first sensor 261 sends a second signal to the controller, the controller determines that the force receiving part 231 is separated from the helical surface 244. The controller controls the motor 241 to stop working at the same time. It should be noted that the communication connection between the controller and the first sensor 261 can be through a cable connection, or through a wireless communication connection such as WiFi or Bluetooth, which is not limited here.

[0071] It should be understood that in other embodiments, in the state where the force receiving part 231 cooperates with the helical surface 244, the detection piece 262 is separated from the first sensor 261, and the first sensor 261 outputs a second signal; in the state where the force receiving part 231 is separated from the helical surface 244, the detection piece 262 cooperates with the first sensor 261, and the first sensor 261 outputs a first signal.

[0072] In the present embodiment, the first end of the support shaft 264 is fixedly inserted into the center hole 248 away from the output shaft 249 of the motor 241, which reduces the space occupied in directions other than the direction of the rotation axis of the driving piece 242, thereby facilitating the miniaturization design of the lock 200.

[0073] Please refer to Figure 8 The detection piece 262 comprises a connecting ring 265 and a detection sheet 266 fixedly connected to the outer periphery of the connecting ring 265. The connecting ring 265 is fixedly sleeved on the second end of the support shaft 264. When the driving piece 242 rotates and the helical surface 244 of the driving part 243 starts to cooperate with the force receiving part 231, the detection sheet 266 starts to cooperate with the first sensor 261, and the first sensor 261 outputs a first signal. With the rotation of the driving piece 242, the helical surface 244 always cooperates with the force receiving part 231, and the contact position between them is displaced along the rotation axis of the driving piece 242. During this period, the signal output by the first sensor 261 remains unchanged, i.e., the first signal is always output. When the locking piece 230 is driven to the second position, the helical surface 244 is separated from the force receiving part 231, and the detection sheet 266 is simultaneously separated from the first sensor 261, and the first sensor 261 outputs a second signal. In the present embodiment, through the arrangement of the detection sheet 266 of the detection piece 262 which rotates synchronously with the driving piece 242, it can be detected in real time whether the helical surface 244 cooperates with the force receiving part 231. The detection is more accurate and sensitive, and therefore the controller can timely and accurately control the start and stop of the motor 241 according to the signal output by the first sensor 261.

[0074] Please refer to Figure 8The driving member 242 comprises a plurality of driving portions 243, the detecting member 262 comprises a plurality of detecting pieces 266, the plurality of detecting pieces 266 are fixedly connected with the connecting ring 265, and the plurality of detecting pieces 266 are uniformly and spacedly arranged along the circumference of the connecting ring 265, and a detecting gap 267 is formed between every two adjacent detecting pieces 266. The plurality of detecting pieces 266 are arranged in one-to-one correspondence with the plurality of driving portions 243, when the detecting member 262 rotates synchronously with the driving member 242, the detecting pieces 266 and the detecting gap 267 can sequentially cooperate with the first sensor 261, when the detecting piece 266 cooperates with the first sensor 261, the first sensor 261 outputs a first signal, and the controller determines that the helical surface 244 cooperates with the stress portion 231 according to the first signal; when the detecting gap 267 cooperates with the first sensor 261, that is, the detecting piece 266 is separated from the first sensor 261, the first sensor 261 outputs a second signal to determine that the helical surface 244 is separated from the stress portion 231, and the controller controls the motor 241 to stop working in time so that the locking member 230 stays at the second position and the locking hook 220 stays at the unlocking position.

[0075] It should be noted that, in the embodiment, the number of the detecting pieces 266 is equal to the number of the driving portions 243, so that the cooperation between the detecting pieces 266 and the first sensor 261 can reliably determine that the helical surface 244 of the driving portion 243 cooperates with the stress portion 231; the positions of the plurality of detecting pieces 266 are arranged in one-to-one correspondence with the positions of the plurality of driving portions 243.

[0076] It should be further noted that the detecting piece 266 and the connecting ring 265 of the embodiment are integrally formed. In other embodiments, the detecting piece 266 and the connecting ring 265 can also be welded or clamped, etc.

[0077] The first sensor 261 can be selected according to needs, please refer to Figure 3 In the embodiment, the first sensor 261 is an optical sensor, which comprises a light emitter 268 and a light receiver 269 arranged oppositely and spacedly, and the light emitter 268 and the light receiver 269 are both in communication connection with the controller; when the detecting member 262 rotates synchronously with the driving member 242, the detecting pieces 266 and the detecting gap 267 sequentially move between the light emitter 268 and the light receiver 269; when the detecting piece 266 moves between the light emitter 268 and the light receiver 269, the light receiver 269 cannot receive the light emitted by the light emitter 268, and the light receiver 269 outputs a first signal; when the detecting gap 267 moves between the light emitter 268 and the light receiver 269, the light receiver 269 receives the light emitted by the light emitter 268, and the light receiver 269 outputs a second signal.

[0078] Please refer to Figure 2 and Figure 3The lock 200 of the embodiment further comprises a second sensor 263 arranged in the housing 210 and configured to detect the position of the locking member 230. Specifically, when the locking member 230 is located at one of the first position and the second position, the locking member 230 cooperates with the second sensor 263, and the second sensor 263 outputs a third signal; when the locking member 230 is located at the other of the first position and the second position, the locking member 230 is separated from the second sensor 263, and the second sensor 263 outputs a fourth signal. In this way, the position of the locking member 230 can be determined, and whether the locking member 230 reliably locks the hook 220 in the locked position can be determined.

[0079] The second sensor 263 can be selected as required. In the embodiment, the second sensor 263 is a microswitch. When the locking member 230 is located at the second position, the locking member 230 presses the second sensor 263, and the second sensor 263 outputs the third signal; when the locking member 230 is located at the first position, the locking member 230 is separated from the second sensor 263, and the second sensor 263 outputs the fourth signal. Of course, in other embodiments, the second sensor 263 can also be a photoelectric sensor, and the like, which is not limited here.

[0080] It should be understood that, in other embodiments, when the locking member 230 is located at the second position, the locking member 230 is separated from the second sensor 263, and the second sensor 263 outputs the fourth signal; when the locking member 230 is located at the first position, the locking member 230 presses the second sensor 263, and the second sensor 263 outputs the third signal.

[0081] It should be understood that, in other embodiments, when the locking member 230 is located at the second position, the locking member 230 is separated from the second sensor 263, and the second sensor 263 outputs the fourth signal; when the locking member 230 is located at the first position, the locking member 230 presses the second sensor 263, and the second sensor 263 outputs the third signal.

[0082] Figure 9 FIG. 3 is a structural schematic view of the locking member 230 in the embodiment of the present application; please refer to Figure 9 The locking member 230 of the embodiment is provided with a groove 232, and the force receiving portion 231 is arranged in the groove 232. When the helical surface 244 cooperates with the force receiving portion 231, the driving member 242 at least partially extends into the groove 232. In this way, the structure of the lock 200 can be more compact.

[0083] Further, the cross section of the stress receiving portion 231 is triangular, and the bottom edge of the stress receiving portion 231 is formed by the bottom wall of the groove 232, and the top end sharp corner of the stress receiving portion 231 cooperates with the helical surface 244. In this way, when the driving member 242 rotates and the helical surface 244 of the driving portion 243 enters the groove 232, the helical surface 244 can be reliably cooperated with the stress receiving portion 231, and then the movement of the contact position of the helical surface 244 and the stress receiving portion 231 is used to drive the locking member 230 to move to the second position.

[0084] Further, the top end sharp corner of the stress receiving portion 231 is rounded, so that the transition is smoother when the helical surface 244 entering the groove 232 cooperates with or separates from the stress receiving portion 231.

[0085] Please refer to Figure 2 , Figure 3 and Figure 9 , the locking member 230 of the embodiment further comprises a blocking surface 233 for cooperating with the lock hook 220; specifically, when the lock hook 220 is in the locked position and the locking member 230 is in the first position, the blocking surface 233 abuts against the lock hook 220, preventing the lock hook 220 from rotating to the unlocking position, so that the lock hook 220 is locked in the locked position.

[0086] Further, please refer to Figure 9 , the locking member 230 is provided with a plug-in hole 234 for plug-in cooperation with the first rotating shaft 251, and the blocking surface 233, the plug-in hole 234 and the stress receiving portion 231 are arranged in sequence. In this way, when the helical surface 244 cooperates with the stress receiving portion 231, the locking member 230 can be reliably driven to rotate around the first rotating shaft 251, and then the locking member 230 is driven to rotate from the first position to the second position, and the blocking surface 233 is separated from the lock hook 220, so as to release the position locking of the lock hook 220.

[0087] Figure 10 is a structural schematic view of the lock 200 in the second perspective view; further, please refer to Figure 9 and Figure 10 , the lock 200 further comprises an emergency pull rod 235, and the outer shell 210 is further provided with a second opening 214, the first end of the emergency pull rod 235 is fixedly connected with the locking member 230, and the second end of the emergency pull rod 235 extends out of the outer shell 210. When an external force is applied to the second end of the emergency pull rod 235 outside the outer shell 210, the locking member 230 can be rotated from the first position to the second position through the emergency pull rod 235 to unlock the lock hook 220; in this way, when the motor 241 fails or is powered off, or the cooperation between the driving member 242 and the stress receiving portion 231 fails, the emergency pull rod 235 can be manually operated to rotate the locking member 230 to the second position, and the position of the lock hook 220 is manually unlocked, so as to ensure the reliability of the unlocking of the lock 200.

[0088] It should be noted that the blocking surface 233, the insertion hole 234, the force receiving portion 231 and the emergency pull rod 235 are arranged in sequence, which can reduce the size of the lock 200 along the axis direction of the first rotating shaft 251.

[0089] It should be further noted that the connection mode of the emergency pull rod 235 and the locking member 230 can be selected as needed, and the emergency pull rod 235 and the locking member 230 of the embodiment are integrally formed. Of course, in other embodiments, the connection mode of the emergency pull rod 235 and the locking member 230 can also be welding or connecting with bolts and the like fasteners.

By arranging the supporting surface 271 on the cover body 270, the reliability of the cooperation between the force receiving portion 231 and the helical surface 244 of the driving portion 243 can be ensured.

[0093] It should be noted that the limiting plate 215 is fixedly connected with the first shell 211 and located between the first shell 211 and the second shell 212. The limiting plate 215 and the first shell 211 are integrally formed; of course, in other embodiments, the limiting plate 215 can also be welded to the first shell 211 or connected with the first shell 211 through bolts and the like fasteners.

[0094] Please refer to Figure 12The cover 270 of the embodiment is provided with a positioning hole 272 which is sleeved with the first rotating shaft 251.

[0095] Further, referring to Figure 12 , the cover 270 is further provided with a limiting groove 273, and the bottom wall of the limiting groove 273 is the supporting surface 271. When the locking member 230 rotates between the first position and the second position, the stress receiving portion 231 is always located in the limiting groove 273. In this way, when the locking member 230 rotates between the first position and the second position, the position stability of the stress receiving portion 231 can be ensured by the limiting groove 273, so that the helical surface 244 of the driving member 242 can enter the recess 232 and reliably cooperate with the stress receiving portion 231 next time.

[0098] It should be noted that the first opening 213 and the second opening 214 are respectively located at two ends of the outer shell 210, so as to avoid the mutual interference of the locking hook 220 and the emergency pull rod 235.

[0099] It should be further noted that, in order to improve the reliability of the connection of the first shell 211 and the second shell 212, the first shell 211 and the second shell 212 are further connected by fasteners such as bolts or screws. In this way, the reliability of the locking member 230, the locking hook 220, the driving assembly 240 and the cover 270 arranged between the first shell 211 and the second shell 212 can also be ensured.
