Description

Technical Field

[0001] The present invention relates to a lock, and in particular to a shopping cart lock and a shopping cart having the same. Background Art

[0002] A shopping cart refers to a trolley used by customers to temporarily store selected goods in large self-service stores such as supermarkets. To facilitate the management of shopping carts, shopping carts are usually locked with locks, such as coin-operated locks.

[0003] In the related art, for a shopping cart lock, an insertion port is usually provided on the side of the lock. When in use, the user needs to pick up the plug-in member with one hand, lean forward and look down at the insertion port, and then insert the plug-in member forcefully after alignment. However, since the insertion direction is lateral insertion, when inserting the plug-in member, the shopping cart will slide horizontally on the ground as the force is applied. At this time, it is necessary to hold the shopping cart with the other hand to successfully lock the cart. Obviously, this locking operation is very inconvenient and cannot be locked and change carts with one hand. In addition, shopping carts are usually connected in series by multiple locks in sequence. In two adjacent shopping carts, the plug-in member at the free end of the upper chain of one shopping cart is inserted into the insertion port of the lock of the other shopping cart and cooperates with the lock tongue in the insertion port. Then, during the movement of the shopping cart, the upper chain of one shopping cart generates a pulling force on the lock of the other shopping cart, which is likely to cause damage to the lock tongue due to the force. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems in the related art to some extent. For this purpose, an object of the present invention is to provide a shopping cart lock and a shopping cart having the same.

[0005] To achieve the above object, on the one hand, according to an embodiment of the present invention, a shopping cart lock is used to lock or release a locked member on a shopping cart. The locked member is an annular member. The shopping cart lock includes:

[0006] A lock housing having a receiving groove and a hanging portion located in the receiving groove. The receiving groove has a first open side that is open upward in the vertical direction and a second open side that is open toward one side in the horizontal direction. The hanging portion is configured such that the locked member can be sleeved from the first open side onto the hanging portion, and when the locked member is sleeved onto the hanging portion, the locked member remains horizontally arranged and at least partially extends out from the second open side;

[0007] A locking mechanism is provided. The locking mechanism is disposed within the lock housing and is capable of switching between a locked state and an unlocked state. When the locking mechanism is in the unlocked state, the locking mechanism releases the locked member to allow the locked member to disengage from the hanging portion. When the locked member is sleeved onto the hanging portion from the first open side, the locked member forces the locking mechanism to switch from the unlocked state to the locked state, so that the locking mechanism locks and fixes the locked member, thereby restricting the locked member from disengaging from the hanging portion.

[0008] According to the shopping cart lock provided by an embodiment of the present invention, the receiving groove has a first open side that opens upward in the vertical direction and a second open side that opens toward one side in the horizontal direction. When locking, the locked member can be sleeved onto the hanging portion from top to bottom, and the locked member is used to force the locking mechanism to switch from the unlocked state to the locked state. Then, the locked member is locked and fixed by the locking mechanism. During this locking process, since the locked member is inserted from top to bottom, the shopping cart will not move under the action of a horizontal force. Moreover, when the locked member is inserted, it can force the locking mechanism to automatically switch to the locked state. Therefore, the user can complete the locking operation with one hand, and the locking operation is simple and convenient. In addition, since the locked member is sleeved onto the hanging portion and remains horizontally arranged, during the movement of the shopping cart, the pulling force generated by the locking chain of one shopping cart on the locking device of another shopping cart acts on the hanging portion and does not act on the locking mechanism. Thus, the locking mechanism is not easily damaged, ensuring higher reliability of the shopping cart. And during the design, the mechanical strength of the locking mechanism can be appropriately reduced, thereby reducing costs.

[0009] In addition, the shopping cart lock according to the above embodiment of the present invention may further have the following additional technical features:

[0010] According to an embodiment of the present invention, the locking mechanism includes:

[0011] A lock catch is provided. The lock catch is disposed within the lock housing and can be switched from an unlocked position to a locked position under the action of the locked member. When the lock catch is in the locked position, a lock hole in a closed state is defined between the lock catch and the hanging portion to lock and fix the locked member sleeved within the lock hole. When the lock catch returns from the locked position to the unlocked position, the lock hole is switched from the closed state to an open state to allow the locked member to be removed from the lock hole and disengage from the hanging portion.

[0012] A switch locking device is provided. The switch locking device is connected to the lock catch and is used to restrict the lock catch in the locked position or drive the lock catch to return from the locked position to the unlocked position.

[0013] According to an embodiment of the present invention, the switch locking device includes:

[0014] A first elastic member, which is disposed between the latch and the lock housing and constantly drives the latch to move towards the unlocking position;

[0015] A stop assembly, which is disposed between the lock housing and the latch and is configured such that when the latch is in the unlocking position, a non-blocking state exists between the stop assembly and the latch to allow the latch to move from the unlocking position to the locking position. When the latch pivots from the unlocking position to the locking position, the state between the stop assembly and the latch switches from non-blocking to blocking to prevent the latch from moving towards the unlocking position.

[0016] According to an embodiment of the present invention, the latch includes:

[0017] A pivoting portion, which is pivotally disposed on the lock housing and is opposite to the hanging portion;

[0018] A pressure-receiving portion, which is formed on the pivoting portion and is configured such that when the latch is in the unlocking position and the locked member is inserted into the lock hole in the open state, the locked member acts on the pressure-receiving portion and applies pressure to drive the pivoting portion to rotate, causing the latch to rotate from the unlocking position to the locking position.

[0019] According to an embodiment of the present invention, a notch is provided on the pivoting portion. When the latch rotates from the unlocking position to the locking position, the notch is closed by the hanging portion to define the lock hole in a closed state.

[0020] According to an embodiment of the present invention, the pressure-receiving portion is formed to extend from the lower edge of the notch towards the outside of the notch.

[0021] According to an embodiment of the present invention, the latch further includes:

[0022] A blocking portion, which is formed on the pivoting portion and is adapted to cooperate with the stop assembly to form a blocking state or a non-blocking state.

[0023] According to an embodiment of the present invention, the hanging portion has a first guiding inclined surface, which slopes downward from top to bottom in the direction close to the latch, and the lower end of the first guiding inclined surface is adjacent to the pressure-receiving portion for guiding the locked member to slide onto the pressure-receiving portion when the locked member is inserted into the lock hole.

[0024] According to an embodiment of the present invention, the first elastic member is a torsion spring, one end of the torsion spring is connected to the lock housing, and the other end of the torsion spring is connected to the latch.

[0025] According to an embodiment of the present invention, the stop assembly includes:

[0026] A stop pin, which is arranged on the lock housing and moves between a blocking position and a release position;

[0027] A second elastic member, which is arranged between the lock housing and the stop pin and constantly drives the stop pin to move towards the blocking position, so as to form the blocking state between the stop pin and the lock catch;

[0028] A driving member, which is arranged on the lock housing and is used to drive the stop pin to move towards the release position against the elastic force of the second elastic member, so as to switch to the non-blocking state between the stop pin and the lock catch.

[0029] According to an embodiment of the present invention, the stop assembly further includes a moving seat, which is relatively fixed to the stop pin, and a first tooth group is arranged on the moving seat; the driving member includes a driving motor and a gear, the gear is arranged on the output shaft of the driving motor, and the gear has a second tooth group meshing with the first tooth group.

[0030] According to an embodiment of the present invention, the end face of the gear facing the moving seat has two opposite limiting parts, and a stop part is arranged on the moving seat;

[0031] When the stop pin is in the release position, the connection line between the two limiting parts is perpendicular to the moving direction of the stop part. When the stop pin moves from the release position to the blocking position, the stop part moves between the two limiting parts, and the connection line between the two limiting parts is parallel to the moving direction of the stop part, so as to limit the movement of the stop part through the two limiting parts.

[0032] According to an embodiment of the present invention, a shielding part is arranged on the wall of the receiving groove opposite to the second open side, and the pivoting part is hidden below the shielding part.

[0033] According to an embodiment of the present invention, the shielding part has a second guiding inclined surface, the second guiding inclined surface inclines downward from top to bottom in the direction close to the hanging part, and the lower end of the second guiding inclined surface is adjacent to the first guiding inclined surface, so as to guide the locked part to slide onto the first guiding inclined surface when the locked part is inserted into the lock hole.

[0034] According to an embodiment of the present invention, the lock housing includes:

[0035] An upper housing, which is provided with an opening part;

[0036] The lower shell is detachably connected to the upper shell. The receiving groove is defined between the opening part and the lower shell. The hanging part is arranged on the lower shell and extends upward into the opening part.

[0037] On the other hand, the shopping cart according to the embodiment of the present invention has the shopping cart lock as described above.

[0038] The shopping cart provided by the embodiment of the present invention has the above-mentioned shopping cart lock. In this way, it can be ensured that the shopping cart is more convenient to use, not easily damaged, and the user experience is better.

[0101] The shopping cart lock and shopping cart according to the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0102] A shopping cart lock is a special lock for locking a shopping cart, which can realize the management of shopping carts. Each shopping cart is provided with a shopping cart lock and a shopping cart chain. The shopping cart lock is fixedly installed on the shopping cart. The shopping cart chain can be directly connected to the shopping cart or connected to the shopping cart lock (as Figure 1 shown). A locked member 50a (50b) is provided at the free end of the shopping cart chain. The locked member 50a (50b) can be a structure such as a link. When locking, the locked member 50a of the shopping cart chain on one shopping cart is locked by the shopping cart lock on another shopping cart. In this way, the two shopping carts are locked together and cannot be separated, thus realizing the management of shopping carts.

[0103] Referring to Figures 1 to 18 shown, the shopping cart lock according to the embodiment of the present invention is used to lock or release the locked member 50a on the shopping cart. The locked member 50a is a ring-shaped member. Exemplarily, the locked member 50a can be a link at the free end of the shopping cart chain 70. The shopping cart lock includes a lock housing 10 and a locking mechanism.

[0104] Specifically, in a specific application, the lock housing 10 is fixed to the push rod 80 of the shopping cart. The lock housing 10 has a receiving groove H10 and a hanging portion 103 located in the receiving groove H10. The receiving groove H10 has a first open side that opens upward in the vertical direction and a second open side that opens toward one side in the horizontal direction. In Figure 1 the example, the upper side and the rear side of the receiving groove H10 are open.

[0105] The hanging portion 103 is configured such that the locked member 50a can be sleeved onto the hanging portion 103 from the first open side. When the locked member 50a is sleeved onto the hanging portion 103, the locked member 50a remains horizontally arranged and at least partially protrudes from the second open side. That is to say, the locked member can be sleeved onto the hanging portion 103 from top to bottom. Since the locked member 50a is an annular member, when the locked member 50a is sleeved onto the hanging portion 103, the locked member 50a is in a horizontal state, and the hanging portion 103 passes upward through the locked member 50a. Moreover, a part of the locked member 50a protrudes horizontally from the second open side. In Figure 1 the example, a part of the locked member 50a protrudes rearward and is connected to the chain 70 of the shopping cart.

[0106] The locking mechanism is provided in the lock housing 10 and can be switched between the locked state and the unlocked state. When the locking mechanism is in the unlocked state, the locking mechanism releases the locked member 50a to allow the locked member 50a to be disengaged from the hanging portion 103. When the locked member 50a is sleeved onto the hanging portion 103 from the first open side, the locked member 50a forces the locking mechanism to switch from the unlocked state to the locked state, so that the locking mechanism locks and fixes the locked member 50a, thereby restricting the locked member 50a from being disengaged from the hanging portion 103.

[0107] That is to say, the locking mechanism has a locked state and an unlocked state. When the locking mechanism is in the unlocked state, the locked member 50a can be sleeved onto the hanging portion 103 from top to bottom. When the locked member 50a is sleeved onto the hanging portion 103 from top to bottom, the locked member 50a contacts the locking mechanism, forcing the locking mechanism to switch from the unlocked state to the locked state. In the locked state, the locking mechanism has a locking effect on the locked member 50a, so that the locked member 50a is locked on the hanging portion 103 and cannot be disengaged from the hanging portion 103. In this way, locking is achieved. When unlocking is required, the locking mechanism is switched to the unlocked state. At this time, the locking mechanism has no locking effect on the locked member 50a, and the locked member 50a can be freely disengaged from the hanging portion 103 to achieve unlocking.

[0108] According to the shopping cart lock provided by an embodiment of the present invention, the receiving groove H10 has a first open side that opens upward in the vertical direction and a second open side that opens toward one side in the horizontal direction. When locking, the locked member 50a can be sleeved on the hanging portion 103 from top to bottom, and the locked member 50a is used to force the locking mechanism to switch from the unlocked state to the locked state, and then the locked member 50a is locked and fixed by the locking mechanism. During this locking process, since the locked member 50a is inserted from top to bottom, the shopping cart will not move due to the horizontal force, and when the locked member 50a is inserted, it can force the locking mechanism to automatically switch to the locked state. Therefore, the user can complete the locking operation by operating the locked member 50a with one hand, and its locking operation is simple and convenient. In addition, since the locked member 50a is sleeved on the hanging portion 103 and remains horizontally arranged, during the movement of the shopping cart, the pulling force generated by the upper locking chain 70 of one shopping cart on the lock of another shopping cart acts on the hanging portion 103, rather than on the locking mechanism. Thus, the locking mechanism is not easily damaged, ensuring higher reliability of the shopping cart. Moreover, during the design, the mechanical strength of the locking mechanism can be appropriately reduced, thereby reducing costs.

[0109] Referring to Figures 3 to 13 As shown, in some embodiments of the present invention, the locking mechanism includes a lock catch 20 and a switch locking device. Among them, the lock catch 20 is arranged in the lock housing 10 and can be switched from the unlocked position to the locked position under the action of the locked member 50a. When the lock catch 20 is in the locked position, a locked hole H11 in a closed state is defined between the lock catch 20 and the hanging portion 103 to lock and fix the locked member 50a sleeved in the locked hole H11. When the lock catch 20 returns from the locked position to the unlocked position, the locked hole H11 switches from the closed state to the open state to allow the locked member 50a to be taken out of the locked hole H11 and then removed from the hanging portion 103. The switch locking device is connected to the lock catch 20 to restrict the lock catch 20 in the locked position or drive the lock catch 20 to return from the locked position to the unlocked position.

[0110] That is to say, the buckle 20 can be switched between an unlocked position and a locked position. During the locking process, when the locked member 50a is sleeved on the hanging portion 103 from top to bottom, the locked member 50a applies a force to the buckle 20, forcing the buckle 20 to switch from the unlocked position to the locked position. At the same time, the switch-locking device can be used to keep the buckle 20 in the locked position. When the buckle 20 is kept in the locked position, the locking hole H11 defined between the buckle 20 and the hanging portion 103 is in a closed state. Since the locking hole H11 is in a closed state, the locked member 50a cannot be taken out from the locking hole H11. Correspondingly, the locked member 50a cannot be disengaged from the hanging portion 103. At this time, the buckle 20 can lock and fix the locked member 50a to achieve locking, and the state of the locking mechanism at this time is the locked state. It should be noted that during the locking process, using the switch-locking device to keep the buckle 20 in the locked position can ensure reliable locking of the buckle 20 to the locked member 50a. During the unlocking process, the switch-locking device can be used to drive the buckle 20 to switch from the locked position to the unlocked position. When the buckle 20 is in the unlocked position, the locking hole H11 is in an open state. At this time, the locked member 50a can be taken out from the locking hole H11. Correspondingly, the buckle 20 can also be disengaged from the hanging portion 103 to achieve unlocking.

[0111] In this embodiment, the buckle 20 is switched between the unlocked position and the locked position, and the switch-locking device is used to keep the buckle 20 in the locked position during locking, and drive the buckle 20 to switch from the locked position to the unlocked position during unlocking. In this way, locking and unlocking can be achieved, and the reliability of locking and unlocking can be ensured.

[0112] Refer to Figures 3 to 13 As shown, in an embodiment of the present invention, the switch-locking device includes a first elastic member 30 and a stopping component 40. Among them, the first elastic member 30 is arranged between the buckle 20 and the lock housing 10 and always drives the buckle 20 to move towards the unlocked position. That is to say, the elastic force provided by the first elastic member 30 acts on the buckle 20 and towards the unlocked position, so that when there is no other external force intervention, the buckle 20 is kept in the unlocked position under the elastic force of the first elastic member 30.

[0113] The stopping component 40 is arranged between the lock housing 10 and the buckle 20, and is configured such that when the buckle 20 is located at the unlocked position, the stopping component 40 and the buckle 20 are in a non-blocking state to allow the buckle 20 to move from the unlocked position to the locked position. When the buckle 20 pivots from the unlocked position to the locked position, the stopping component 40 and the buckle 20 switch from the non-blocking state to the blocking state to prevent the buckle 20 from moving towards the unlocked position.

[0114] That is to say, the stop component 40 cooperates with the latch 20. When the latch 20 is in the unlocked position, the cooperation state between the stop component 40 and the latch 20 is a non-blocking state. This non-blocking state means that the stop component 40 does not exert a blocking effect on the latch 20. At this time, the latch 20 can move from the unlocked position to the locked position. Thus, when the latch 20 is in the unlocked position, the stop component 40 is in a non-blocking state. In this case, the locked member 50a can be placed between the hanging portion 103 and the latch 20, and a force is applied to the latch 20 to force the latch 20 to switch from the unlocked position to the locked position, thereby locking and fixing the locked member 50a. When the latch 20 moves from the unlocked position to the locked position, the first elastic member 30 is forced to deform and store elastic energy, and this process is the locking process.

[0115] When the latch 20 switches from the unlocked position to the locked position, the stop component 40 acts, and then the cooperation state between the stop component and the latch 20 switches to a blocking state. This blocking state means that the stop component 40 exerts a blocking effect on the latch 20, so that the latch 20 cannot return from the locked position to the unlocked position. Thus, under the blocking action of the stop component, the latch 20 can be kept in the locked position, thereby ensuring that the locked member 50a remains locked and fixed. As described above, since the first elastic member 30 is forced to deform and store elastic energy when the latch 20 moves from the unlocked position to the locked position, when it is necessary to release the locking of the locked member 50a, the stop component can be first switched from the blocking state to the non-blocking state. At this time, the stop component no longer blocks the latch 20 from moving to the unlocked position. Thus, the first elastic member 30 resumes deformation, and then forces the latch 20 to quickly return to the unlocked position, and the locked member 50a can be disengaged from the hanging portion 103 to unlock the locked member 50a, and this process is the unlocking process.

[0116] In this embodiment, the first elastic member 30 constantly drives the latch 20 to move towards the unlocking position. Moreover, when the latch 20 switches from the unlocking position to the locking position, the stop assembly 40 and the latch 20 switch from a non-blocking state to a blocking state to prevent the latch 20 from moving towards the unlocking position. In other words, after the latch 20 moves to the locking position to lock the locked member 50a, the stop assembly 40 automatically switches to the blocking state, thereby preventing the latch 20 from moving towards the unlocking position. Thus, even if vibrations such as collisions occur, under the blocking action of the stop assembly 40, the latch 20 will not move towards the unlocking position, thereby preventing the problem of abnormal unlocking of the latch 20 and improving the reliability of the shopping cart lock. In addition, by using the lock hole H11 defined between the latch 20 and the hanging portion 103 to define a closed state or an open state, when the lock hole H11 is in the closed state, the locked member 50a on the shopping cart can be locked, and when the lock hole H11 is in the open state, the elastic force of the first elastic member 30 can be used to quickly unlock the locked member 50a. This locking and unlocking method of the latch 20 is simple, convenient, and fast.

[0117] It should be emphasized that in the related art, the lock on the shopping cart usually has an elastic member constantly driving the lock tongue to be in the locking position. That is to say, by using the elastic force of the elastic member, the lock tongue is forced to maintain the locking position to lock the locked member 50a on the shopping cart. In this locking method, when the shopping cart or the lock is impacted, in fact, when collecting and transferring shopping carts in the supermarket, collisions often occur between multiple shopping carts. Therefore, it is easy for the elastic member in the lock to be impacted, and finally the lock tongue shakes or shifts, resulting in problems such as abnormal unlocking.

[0118] In the shopping cart lock of this embodiment, the elastic force provided by the first elastic member 30 forces the latch 20 to be constantly in the unlocking position instead of the locking position. Moreover, when the latch 20 is in the locking position, the stop component is used to block the latch 20 from moving towards the unlocking position. In other words, in this embodiment, it is the blocking action of the stop component that ensures the latch 20 stays in the locking position, rather than using the elastic force of the first elastic member 30 to stay in the locking position. Therefore, the latch 20 will not shake or shift due to external forces such as impacts, and thus can ensure the reliable stability of the latch 20 and will not have problems such as abnormal unlocking.

[0119] Refer to Figure 4 and Figures 6 to 13As shown, in an embodiment of the present invention, the latch 20 includes a pivoting portion 201 and a pressure-receiving portion 202. Among them, the pivoting portion 201 is pivotally provided on the lock housing 10 and is opposite to the hanging portion 103. The pressure-receiving portion 202 is formed on the pivoting portion 201 and is configured such that when the latch 20 is in the unlocked position and the locked member 50a is inserted into the open lock hole H11, the locked member 50a acts on the pressure-receiving portion 202 and applies pressure to drive the pivoting portion 201 to rotate, so that the latch 20 rotates from the unlocked position to the locked position.

[0120] That is to say, the pivoting portion 201 can pivot relative to the lock housing 10 and the hanging portion 103, and the pressure-receiving portion 202 is located on the pivoting portion 201. Preferably, the pressure-receiving portion 202 is integrally formed with the pivoting portion 201. The pressure-receiving portion 202 is used for the locked member 50a to apply pressure to force the pivoting portion 201 to rotate, thereby rotating the latch 20 from the unlocked position to the locked position. Specifically, when the latch 20 is in the unlocked position, at this time, the lock hole H11 defined between the latch 20 and the hanging portion 103 is in an open state (as Figure 11 shown). In this state, the locked member 50a is inserted into the lock hole H11, so that the locked member 50a contacts the pressure-receiving portion 202. At the same time, a pressure force is applied to the locked member 50a, so that this force acts on the pressure-receiving portion 202, and then drives the pressure-receiving portion 202 and the pivoting portion 201 to rotate (as Figure 11 shown by the arrow A), and finally the latch 20 is rotated from the unlocked position to the locked position (as Figure 12 shown).

[0121] In other words, in this embodiment, the latch 20 adopts a pivoting motion mode to switch between the unlocked position and the locked position. Moreover, by using the pressure-receiving portion 202 of the latch 20 to withstand the force applied by the locked member 50a, the latch 20 can be driven to rotate from the unlocked position to the locked position, thereby realizing locking the locked member 50a. Its structure is simple, and the locking operation is very convenient and labor-saving.

[0122] It should be noted that the latch 20 can also adopt a moving mode to realize the switching between the unlocked position and the locked position. Correspondingly, the latch 20 can be configured as a structure that slides in the lock housing 10, which will not be described in detail here.

[0123] Referring to Figure 10 and Figure 13 shown, in an example of the present invention, a notch H201 is provided on the pivoting portion 201. When the latch 20 rotates from the unlocked position to the locked position, the notch H201 is closed by the hanging portion 103 to define the lock hole H11 in a closed state.

[0124] In this embodiment, by providing a notch H201 on the pivoting portion 201, when the latch 20 rotates to the locking position, the notch H201 is closed by the hanging portion 103, and thus the lock hole H11 in the above-mentioned closed state can be formed. Its structure is simple, and forming the lock hole H11 facilitates locking the locked member 50a.

[0125] Advantageously, the pressure-receiving portion 202 is formed to extend from the lower edge of the notch H201 to the outside of the notch H201. In this way, it is convenient for the locked member 50a to press on the pressure-receiving portion 202 when being inserted downward into the lock hole H11, thereby ensuring more convenient locking. In addition, when the latch 20 is in the locking position, the pressure-receiving portion 202 is adjacent to the hanging portion 103 and is located at the bottom of the lock hole H11. In this way, the pressure-receiving portion 202, the hanging portion 103 and the pivoting portion 201 jointly define the lock hole H11 in the closed state.

[0126] Optionally, an anti-slip structure 2021 for increasing the friction between the locked member 50a and the pressure-receiving portion 202 can be provided on the pressure-receiving portion 202. The anti-slip structure 2021 can be a tooth-shaped protrusion or the like. In this way, when the locked member 50a acts on the pressure-receiving portion 202, it is not easy to slide, ensuring that the pressure-receiving portion 202 can drive the latch 20 to rotate under the pressure of the locked member 50a.

[0127] More advantageously, the notch H201 is arc-shaped, and the extending direction of the pressure-receiving portion 202 is the tangent direction of the lower edge of the notch H201. In this way, it is convenient for the locked member 50a to press on the pressure-receiving portion 202, and when the latch 20 rotates to the locking position, the pressure-receiving portion 202 is generally horizontal, so that the lock hole H11 jointly defined by the pressure-receiving portion 202, the hanging portion 103 and the pivoting portion 201 maintains a better closed state.

[0128] Referring to Figure 4 and Figures 6 to 13 As shown, in an embodiment of the present invention, the latch 20 further includes a stop portion 203. The stop portion 203 is formed on the pivoting portion 201 and is adapted to cooperate with the stop assembly 40 to form a blocking state or a non-blocking state. Preferably, the stop portion 203 is provided at a position on the pivoting portion 201 opposite to the pressure-receiving portion 202.

[0129] That is to say, the stop portion 203 can cooperate with the stop assembly 40. When the latch 20 rotates to the locking position, the stop assembly can abut against the stop portion 203, thereby restricting the latch 20 from rotating to the unlocking position, thus ensuring the reliability of locking.

[0130] Referring to Figures 1 to 12As shown, in an embodiment of the present invention, the hanging portion 103 has a first guiding inclined surface S103. The first guiding inclined surface S103 is inclined downward from top to bottom in the direction close to the lock catch 20, and the lower end of the first guiding inclined surface S103 is adjacent to the pressure receiving portion 202, so as to guide the locked member 50a to slide onto the pressure receiving portion 202 when the locked member 50a is inserted into the lock hole H11.

[0131] That is to say, when the locked member 50a is inserted into the open lock hole H11, the locked member 50a contacts the guiding inclined surface and slides downward along the guiding inclined surface onto the pressure receiving portion 202, and then presses the pressure receiving portion 202 to force the lock catch 20 to rotate. In this way, by using the guiding function of the guiding inclined surface, it is convenient for the locked member 50a to be quickly inserted into the lock hole H11 and contact the pressure receiving portion 202, improving the convenience during the locking operation.

[0132] Preferably, the first elastic member 30 is a torsion spring. One end of the torsion spring is connected to the lock housing 10, and the other end of the torsion spring is connected to the lock catch 20. In this way, by using the elastic force provided by the torsion spring, the lock catch 20 can quickly return from the locked position to the unlocked position, ensuring that the unlocking is faster and more reliable.

[0133] Refer to Figures 7 to 10 As shown, in some embodiments of the present invention, the stopping assembly 40 includes a stopping pin 401, a second elastic member 402 and a driving member 403. Among them, the stopping pin 401 is arranged on the lock housing 10 and moves between a blocking position and a releasing position. The second elastic member 402 is arranged between the lock housing 10 and the stopping pin 401 and always drives the stopping pin 401 to move towards the blocking position, so as to form the blocking state between the stopping pin 401 and the lock catch 20. The driving member 403 is arranged on the lock housing 10 and is used to drive the stopping pin 401 to move towards the releasing position against the elastic force of the second elastic member 402, so as to switch to the non-blocking state between the stopping pin 401 and the lock catch 20.

[0134] In specific use, when locking is required, the lock catch 20 rotates from the unlocking position to the locking position. Under the elastic force of the second elastic member 402, the stop pin 401 quickly moves to the blocking position. A blocking state can be formed between the stop pin 401 and the lock catch 20. For example, the stop pin 401 extends below the blocking portion 203. In this way, due to the blocking effect of the stop pin 401 on the blocking portion 203, the lock catch 20 cannot rotate towards the unlocking position, thereby ensuring that the lock catch 20 remains in the locking position and achieving reliable locking. When unlocking is required, the stop pin 401 is driven by the driving member 403 to move from the blocking position to the release position. At this time, the state between the stop pin 401 and the lock catch 20 switches to a non-blocking state. For example, the stop pin moves to one side of the blocking portion 203. In this way, the stop pin releases the block on the blocking portion 203, and the lock catch 20 quickly returns to the unlocking position under the elastic force of the first elastic member 30, thus achieving quick unlocking.

[0135] In this embodiment, by using the movement of the stop pin 401 to achieve the switching of the cooperation state with the lock catch 20, the stop pin 401 can quickly switch to the blocking position under the action of the second elastic member 402, ensuring quick and reliable locking of the lock catch 20. And when the stop pin 401 moves to the release position under the drive of the driving member 403, it ensures that the lock catch 20 is quickly unlocked under the action of the first elastic member 30.

[0136] Refer to Figures 7 to 10 and Figures 14 to 15 As shown in the figure, in an embodiment of the present invention, the stop assembly 40 further includes a moving seat 404. The moving seat 404 is relatively fixed to the stop pin 401, and a first tooth group is provided on the moving seat 404. The driving member 403 includes a driving motor 4031 and a gear 4032. The gear 4032 is provided on the output shaft of the driving motor 4031, and the gear 4032 has a second tooth group meshing with the first tooth group.

[0137] When the driving motor 4031 works, the driving motor 4031 drives the gear 4032 to rotate. Since the second tooth group on the gear 4032 meshes with the first tooth group on the moving seat 404, when the gear 4032 rotates, it can drive the moving seat 404 and the stop pin 401 thereon to move between the blocking position and the release position. In this way, the driving of the stop pin 401 is realized, and its structure is simple and the driving is reliable.

[0138] Exemplarily, a groove 4041 is provided on one side surface of the moving seat 404. The gear 4032 is located in the groove 4041, and the first tooth group is provided on the top wall or the bottom wall of the groove 4041. In this way, it can ensure reliable meshing between the second tooth group on the gear 4032 and the first tooth group on the moving seat 404.

[0139] Refer to Figure 15As shown, in an embodiment of the present invention, the first tooth group is at least two rows, and each row of the first tooth group has a plurality of first tooth portions 4042 arranged at intervals in a first direction. The multiple rows of the first tooth group are arranged at intervals in a second direction, and the first tooth portions 4042 in adjacent two rows of the first tooth group are arranged in a staggered manner. The first direction is perpendicular to the second direction.

[0140] The second tooth group is at least two rows, and each second row of the second tooth group has a plurality of second tooth portions 4032a arranged at intervals along the circumferential direction of the gear 4032. The multiple rows of the second tooth group are arranged at intervals in the axial direction of the gear 4032, and the second tooth portions 4032a in adjacent two rows of the second tooth group are arranged in a staggered manner.

[0141] The first tooth portion 4042 in each row of the first tooth group meshes with the second tooth portion 4032a in the corresponding row of the second tooth group.

[0142] In this embodiment, by using the meshing of the multiple rows of the first tooth group arranged in a staggered manner and the multiple rows of the second tooth group arranged in a staggered manner respectively, in this way, the transmission can be made more smooth and reliable. Moreover, when designing the gear 4032 in a smaller space, by using the cooperation of the multiple rows of the first tooth group and the multiple rows of the second tooth group, the force-bearing magnitude can be increased, and the requirements for the machining precision and material strength of the gear 4032 can also be reduced, saving costs.

[0143] Advantageously, the gear 4032 is a semi-tooth gear 4032. By using the semi-tooth gear 4032, after the gear 4032 rotates within a certain angle range, the second tooth group on the gear 4032 disengages from the first tooth group on the moving seat 404. In this way, it is convenient for the second elastic member 402 to drive the moving seat 404 and the stop pin 401 thereon to return to the blocking position, and problems such as jamming of the drive motor 4031 can also be prevented.

[0144] Exemplarily, the second elastic member 402 is a compression spring. One end of the compression spring abuts against the moving seat 404, and the other end of the compression spring abuts against the lock housing 10. Optionally, the stop assembly further includes a guide post 405. The guide post 405 is slidably inserted through the moving seat 404, and the compression spring is sleeved on the guide post 405. In this way, the reliable compression of the compression spring can be ensured.

[0145] Refer to Figures 16 to 18 As shown, in an embodiment of the present invention, the end face of the gear 4032 facing the moving seat 404 has two opposite limiting portions 4032b, and the moving seat 404 has a stop portion 4043.

[0146] When the stop pin 401 is in the release position, the line connecting the two limiting portions 4032b is perpendicular to the moving direction of the stop portion 4043. When the stop pin 401 moves from the release position to the blocking position, the stop portion 4043 moves between the two limiting portions 4032b, and the line connecting the two limiting portions 4032b is parallel to the moving direction of the stop portion 4043, so as to limit the movement of the stop portion 4043 through the two limiting portions 4032b.

[0147] That is to say, when the stop pin 401 is in the release position, the line connecting the two limiting portions 4032b is perpendicular to the moving direction of the stop portion 4043. As Figure 17 shown, the line connecting the two limiting portions 4032b is in the up-down direction, while the moving direction of the moving seat 404 and the stop portion 4043 thereon is in the horizontal direction. In this state, if the lock 20 rotates to the locked position, the elastic force of the second elastic member 402 can force the moving seat 404 and the stop pin 401 to quickly move to the blocking position. Correspondingly, the stop portion 4043 can move between the two limiting portions 4032b. Then, by driving the gear 4032 to rotate 90°, at this time, the line connecting the limiting portions 4032b on the gear 4032 can be switched to the horizontal direction (as Figure 18 shown), and are respectively located on both sides of the stop portion 4043 in the horizontal direction, so as to limit the movement of the stop portion 4043 in the horizontal direction. Correspondingly, the moving seat 404 where the stop portion 4043 is located and the stop pin 401 connected to the moving seat 404 cannot move in the horizontal direction. Thus, in this embodiment, after the stop pin 401 moves to the blocking position, the cooperation between the stop portion 4043 and the two limiting portions 4032b can be used to lock the stop pin 401, block the left-right movement of the stop pin 401 caused by resonance, thereby improving the reliability of the stop of the stop pin 401 on the lock 20, preventing abnormal unlocking problems, and further improving the locking reliability and anti-theft effect of the locking mechanism.

[0148] Referring to Figures 1 to 6 shown, in an embodiment of the present invention, a shielding portion 104 is provided on the wall of the receiving groove H10 opposite to the second open side, and the pivoting portion 201 is hidden below the shielding portion 104.

[0149] In this embodiment, the pivoting portion 201 is shielded by the shielding portion 104, which can prevent others from using destructive tools to damage the pivoting portion 201. That is to say, the shielding portion 104 can protect the lock 20 and prevent the lock 20 from being maliciously damaged.

[0150] Advantageously, the shielding portion 104 has a second guiding inclined surface S104, which slopes downward from top to bottom in a direction close to the hanging portion 103, and the lower end of the second guiding inclined surface S104 is adjacent to the first guiding inclined surface S103, so as to guide the locked member 50a to slide onto the first guiding inclined surface S103 when the locked member 50a is inserted into the lock hole H11.

[0151] When the user inserts the locked member 50a into the lock hole H11 in the open state, it is not necessary to accurately align the locked member 50a with the lock hole H11. It is only necessary to insert the locked member 50a into the lock hole H11 with a rough alignment. If the locked member 50a deviates to one side, the guiding effect on the first guiding inclined surface S103 can enable the locked member 50a to be inserted into the lock hole H11. If the locked member 50a deviates to the other side, the guiding effect of the second guiding inclined surface S104 can also enable the locked member 50a to be inserted into the lock hole H11. In this way, the convenience of the user's operation during use is improved, and the user experience is better.

[0152] Refer to Figures 1 to 2 As shown, in an embodiment of the present invention, the lock housing 10 includes an upper housing 101 and a lower housing 102. The upper housing 101 is provided with an opening portion 1011; the lower housing 102 is detachably connected to the upper housing 101, and the receiving groove H10 is defined between the opening portion 1011 and the lower housing 102. The hanging portion 103 is provided on the lower housing 102 and extends upward into the opening portion 1011. In this way, it is convenient for the processing of the lock housing 10, and it is also convenient to form the receiving groove H10 and the hanging portion 103 on the lock housing 10. In addition, the assembly is convenient.

[0153] It can be understood that the shopping cart lock may further include a battery 90 and an electrical box 91. A battery 90 cavity is defined in the upper housing 101 and the lower housing 102, and the battery 90 is accommodated in the battery 90 cavity. The electrical box 91 is used for installing a circuit board, and the electrical box 91 is fixed between the upper housing 101 and the lower housing 102.

[0154] The embodiment of the present invention also provides a shopping cart having the above-mentioned shopping cart lock.

[0155] According to the shopping cart provided by the embodiment of the present invention, having the above-mentioned shopping cart lock, in this way, it can be ensured that the shopping cart is more convenient to use, not easily damaged, and the user experience is better.
