All the contents of this application are incorporated herein by reference.

[0002] This application relates to the field of battery technology, specifically to a locking mechanism, a battery assembly, a power - consuming device, and a locking device.

Background Art

[0003] With the progress of science and technology, the battery industry has developed rapidly, and the market share and usage frequency of electric devices have also been increasing. Transportation vehicles adopting electric drive, such as electric vehicles, are gradually emerging in various application scenarios. In order to improve the convenience of electric devices, especially transportation vehicles with electric drive, substations for rapid battery replacement have emerged in the market. However, electric devices always need to perform power - exchange operations. In the process of power - exchange, the locking mechanism between the battery and the power - consuming device needs to be switched between locking and unlocking many times. Therefore, by locking and fixing and separating the battery and the power - consuming device, problems such as wear or damage to the locking mechanism, relatively short service life of the locking mechanism, and poor usage reliability are likely to occur, further causing inconvenience in power - exchange and concerns about usage safety.

Summary of the Invention

Problems to be Solved by the Invention

[0004] Embodiments of this application provide a locking mechanism, a battery assembly, a power - consuming device, and a locking device that can effectively improve the service life and usage reliability of the locking mechanism.

Means for Solving the Problems

[0005] According to a first aspect, an embodiment of the present application provides a locking mechanism for bonding or detaching a lock base along a first direction, the locking mechanism comprising a sleeve, a locking member, an adjustment member, and a clamping assembly, wherein the locking member is movably mounted in the sleeve and has a locked state and an unlocked state, the locking member is configured to bond the locking mechanism and the lock base along a first direction by engaging with the lock base when in the locked state, the locking member is configured to release from the lock base when in the unlocked state, thereby allowing the locking mechanism and the lock base to detach in a first direction, the adjustment member is rotatably connected in the sleeve about an axis extending along a first direction, the adjustment member is screwed onto the locking member, and the adjustment member is configured to switch the locking member between a locked state and an unlocked state by activating the locking member relative to the sleeve when the adjustment member rotates relative to the sleeve, the clamping assembly is configured to prevent the locking member from moving relative to the adjustment member in the first direction toward the lock base when the locking member is in the locked state.

[0006] In the above proposed technology, a locking member and an adjustment member are installed in the locking mechanism, and by screwing the locking member and the adjustment member together, the locking member is activated relative to the sleeve when the adjustment member is rotated, thereby enabling the locking member to be switched between a locked state and an unlocked state. This allows the locking mechanism and the locking base to be bonded or detached along a first direction by engaging or disengaging the locking member from the locking base. By installing a tightening assembly on the locking mechanism, the tightening assembly can prevent the locking member from moving relative to the adjusting member in the direction toward the lock base when the locking member is in the locked state. In other words, when the locking member engages with the lock base and the locking mechanism and lock base are bonded in the first direction, the locking member and adjusting member can be further locked by the action of the tightening assembly. This prevents the locking member from moving toward the lock base relative to the adjusting member, further preventing the locking member from detaching from the adjusting member in the first direction. By adopting a locking mechanism with such a structure, the risk of the locking member and adjusting member detaching from each other when the locking member and lock base engage with each other can be further reduced, improving the stability and reliability of the mutual locking between the locking mechanism and the lock base. At the same time, the tightening assembly can transfer the force applied to the screw structure between the locking member and the adjusting member to the tightening assembly, thereby mitigating the phenomenon of damage to the sliding teeth or screw structure between the locking member and the adjusting member, reducing the risk of poor threading between the locking member and the adjusting member, and further improving the service life and reliability of the locking mechanism.

[0007] In some embodiments, a clamping assembly is mounted on a locking member, and an adjustment member has a contact surface, and the clamping assembly is configured such that when the locking member is in a locked state, the adjustment member contacts the contact surface in a first direction toward the locking base.

[0008] In the above proposed technology, the fastening assembly is mounted on the locking member, and the adjustment member has a contact surface that abuts against the fastening assembly. When the locking member is in the locked state, the fastening assembly abuts against the contact surface in the first direction in which the adjustment member is toward the locking base, thereby preventing the locking member from moving in the first direction relative to the adjustment member in the direction toward the locking base. This transfers the force applied to the screw structure between the locking member and the adjustment member between the contact surface of the fastening assembly and the adjustment member, mitigating the phenomenon of damage to the sliding teeth or screw structure between the locking member and the adjustment member.

[0009] In some embodiments, the locking member has a mounting portion inserted into the adjustment member along a first direction, the inner surface of the adjustment member includes a contact surface, and the fastening assembly includes a locking member, the locking member is movably mounted in the mounting portion, and the locking member is used to protrude from the outer circumferential surface of the mounting portion and then contact the contact surface, or to retract from the contact surface after returning to the mounting portion.

[0010] In the above proposed technology, the locking member has a mounting portion that is inserted inside the adjustment member, and the contact surface is located on the inner surface of the adjustment member. This allows the locking member of the fastening assembly to protrude from the outer circumferential surface of the mounting portion and then contact the contact surface, thereby preventing the fastening assembly from moving in a first direction relative to the adjustment member and in a direction toward the lock base. Conversely, by releasing the contact surface after the locking member of the fastening assembly returns to the mounting portion, the locking member can be made movable relative to the adjustment member. The structure is simple and easy to implement.

[0011] In some embodiments, the fastening assembly further includes a movable member, which is movably mounted within the mounting portion along a first direction, and is configured to bring the locking member into contact with or disengage from a contact surface by pushing the locking member outward from the outer surface of the mounting portion or allowing the locking member to return to the mounting portion when moving along the first direction relative to the mounting portion.

[0012] In the above proposed technology, the fastening assembly is further provided with a movable member for pushing the locking member so that it protrudes from the outer circumferential surface of the mounting portion and for allowing the locking member to return to the mounting portion. By positioning the movable member to be movable within the mounting portion along a first direction, the movable member can push the locking member so that it protrudes from the outer circumferential surface of the mounting portion when it moves relative to the mounting portion in one direction of the first direction, thereby preventing the locking member from returning, and can release contact with the locking member when it moves relative to the mounting portion in another direction of the first direction, thereby enabling the locking member to contact or release contact with a contact surface.

[0013] In some embodiments, the adjustment member is configured such that when it rotates relative to the sleeve, the locking member can be moved along a first direction between a first position and a second position, where when the locking member is in the first position, the locking member is in a locked state, and when the locking member is in the second position, the locking member is in an unlocked state, wherein the adjustment member is provided with an action part which contacts the moving member when the locking member moves from the second position to the first position and can push the moving member to move, thereby pushing the moving member so that the locking member protrudes from the outer circumferential surface of the mounting part, and can separate from the moving member when the locking member moves from the first position to the second position, thereby allowing the moving member to return the locking member to the mounting part.

[0014] In the above proposed technology, the adjustment member allows the locking member to have a first position and a second position in the first direction by switching the locking member between a locked state and an unlocked state and simultaneously moving the locking member along a first direction relative to the sleeve. By installing an execution part on the adjustment member, the execution part comes into contact with the moving member when the locking member moves from the second position to the first position and pushes the moving member to move, so that the locking member can protrude from the outer surface of the mounting part due to the pushing motion of the moving member. Furthermore, the execution part moves when the locking member moves from the first position to the second position. By separating the component and releasing the constraint on the movable member of the execution unit, the movable member can be allowed to return the locking member to the mounting unit. This allows the locking member to be moved along the first direction, thereby switching between the locked and unlocked states. Simultaneously, the locking member of the fastening assembly protrudes from the outer surface of the mounting unit due to the engagement between the movable member and the execution unit, or the locking member of the fastening assembly can be allowed to return to the mounting unit, thereby realizing the interlocking of the locking mechanism. This eliminates the need for additional drive mechanisms or manual intervention, which is advantageous in reducing the difficulty of operating the locking mechanism.

[0015] In some embodiments, the execution portion and the mounting portion are arranged along a first direction, and a projection is provided at the end of the execution portion facing the mounting portion, the projection being inserted into the mounting portion and configured to contact the moving member.

[0016] In the above proposed technology, by providing a protrusion at the end of the execution part that faces the mounting part along the first direction, the protrusion can be inserted into the mounting part and come into contact with the movable member when the mounting part is close to the execution part along the first direction, thereby improving the effect of the execution part pushing the movable member to move.

[0017] In some embodiments, a housing cavity is formed inside the mounting portion, the housing cavity penetrates the end of the mounting portion near the execution portion along a first direction, and the housing cavity is for the insertion of a protrusion, where the movable member is movably installed within the housing cavity along the first direction, and a mounting hole is provided on the outer circumferential surface of the mounting portion, the mounting hole communicates with the housing cavity, and the locking member is movably installed within the mounting hole.

[0018] In the above proposed technology, a housing cavity for accommodating the movable member is installed inside the mounting portion, and the housing cavity penetrates one end of the mounting portion along a first direction, thereby facilitating insertion of the protrusion of the execution portion into the housing cavity, and thus enabling mutual contact between the protrusion and the movable member, which is advantageous in simplifying the structural complexity of the locking mechanism. Furthermore, a mounting hole communicating with the housing cavity is provided on the outer circumferential surface of the mounting portion, and a locking member is movably installed within the mounting hole, so that when the movable member moves along the first direction within the housing cavity, the locking member can be pushed outward from the outer circumferential surface of the mounting portion through the mounting hole, or the third locking portion can be allowed to return to the mounting portion through the mounting hole, resulting in a simple structure and easy implementation.

[0019] In some embodiments, the clamping assembly further includes a first elastic member positioned between the moving member and the mounting portion, the first elastic member being driven to move the moving member in a direction toward the execution portion along a first direction, thereby allowing the moving member to return to the mounting portion.

[0020] In the above proposed technology, a first elastic member is further installed between the movable member and the mounting part. The first elastic member can apply a force to the movable member in a direction closer to the execution part along the first direction, thereby allowing the movable member to automatically return to a position that allows the locking member to return to the mounting part after the movable member has moved away from the execution part. This prevents the movable member from returning to its original position, thus mitigating the phenomenon of the contact surfaces of the locking member and the adjustment member coming into contact incorrectly, while also eliminating the need for manual intervention and making operation and use easier.

[0021] In some embodiments, a first stopper is installed inside the mounting portion, and a second stopper is installed on the movable member. The first and second stoppers engage with each other to limit the range of movement of the movable member relative to the mounting portion in a first direction.

[0022] In the above proposed technology, a first stopper portion and a second stopper portion are installed on the mounting portion and the movable member, respectively. The fitting of the first and second stopper portions makes it possible to restrict the range of movement of the movable member in the first direction relative to the mounting portion. This allows the movable member to accurately switch between a position in which the locking member is pushed outward from the outer surface of the mounting portion along the first direction and a position in which the locking member is allowed to return to the mounting portion. This is advantageous for improving the accuracy of the locking member contacting and releasing the contact surface, while also providing a certain stopper action to the movable member, thereby reducing the risk of the movable member detaching from the mounting portion.

[0023] In some embodiments, the first stopper portion is a stopper block installed on the inner circumferential surface of the mounting portion, and the second stopper portion is a groove installed on the outer circumferential surface of the movable member, with at least a portion of the stopper block being housed in the groove.

[0024] In the above technical solution, the first stopper portion and the second stopper portion are respectively a stopper block installed on the inner circumferential surface of the mounting portion and a concave groove on the outer circumferential surface of the moving member. By inserting the stopper block into the concave groove, when the moving member moves relative to the mounting portion, the stopper block abuts against two groove side walls facing the first direction of the concave groove, and by the fitting of the stopper block and the concave groove, the movement range of the moving member in the first direction can be restricted. The structure is simple, easy to implement, and has relatively high stability.

[0025] In some embodiments, the first stopper portion is an annular stopper block extending along the circumferential direction of the moving member, and the second stopper portion is an annular concave groove extending along the circumferential direction of the moving member.

[0026] In the above technical solution, by installing both the first stopper portion and the second stopper portion in an annular structure, it is advantageous for further improving the stability and reliability of the fitting of the first stopper portion and the second stopper portion to restrict the moving member.

[0027] In some embodiments, on the moving member, a guide slope is formed to abut against the locking member and push the locking member to protrude from the outer circumferential surface of the mounting portion.

[0028] In the above technical solution, by installing a guide slope on the moving member for the locking member to abut against, when the moving member moves along the first direction, the locking member protrudes from the outer circumferential surface of the mounting portion under the guidance of the guide slope. It can be made easy for the moving member to protrude the locking member from the outer circumferential surface of the mounting portion or allow the locking member to return into the mounting portion. Thereby, by adopting a locking mechanism with such a structure, the phenomenon of immobility between the moving member and the locking member can be reduced.

[0029] In some embodiments, the fastening assembly includes a plurality of locking members arranged at intervals along the circumferential direction of the mounting portion.

[0030] In the above proposed technology, the fastening assembly is equipped with multiple locking members that are spaced apart along the circumferential direction of the mounting portion. In other words, when all of the multiple locking members protrude from the outer circumferential surface of the mounting portion, the multiple locking members are arranged to surround the mounting portion. This structure further improves the structural stability and robustness of the mutual contact between the fastening assembly and the adjustment member, and is advantageous in improving the effect of the fastening assembly in sharing the force applied to the screw structure between the locking member and the adjustment member.

[0031] In some embodiments, the locking member is spherical.

[0032] In the above proposed technology, by installing the locking member in a spherical structure, it is made easier to push the locking member so that it protrudes from the outer surface of the mounting part when the movable member moves along the first direction relative to the mounting part, or to allow the locking member to return to the mounting part, thereby reducing the phenomenon of the movable member and the locking member becoming immobile from each other.

[0033] In some embodiments, the locking member includes a connecting portion and a locking portion, the connecting portion extending along a first direction and inserted into a sleeve, the connecting portion and the adjustment member being screwed together, the locking portion located outside the sleeve and connected to the end of the connecting portion away from the sleeve, the locking portion protruding from the outer circumferential surface of the connecting portion along its extending direction, the locking portion being used to engage with a lock base, the extending direction of the locking portion being perpendicular to the first direction, and the locking member can be switched between a locked state and an unlocked state by rotating the connecting portion by rotating the adjustment member relative to the sleeve, thereby engaging or disengaging the locking portion with the lock base.

[0034] In the above proposed technology, the locking member is provided with a connecting portion and a locking portion connected to one end of the connecting portion. The locking portion protrudes from the outer circumferential surface of the connecting portion in its extending direction. The connecting portion is inserted into the sleeve along the first direction and screwed into the adjustment member. This allows the adjustment member to rotate the connecting portion when it rotates, thereby allowing the locking portion to rotate together with the connecting portion. As a result, the extending direction of the locking portion changes in a plane perpendicular to the first direction, allowing the locking portion to lock or release from the lock base after rotation. Furthermore, the locking mechanism can be bonded to or detached from the lock base in the first direction.

[0035] In some embodiments, a third stopper is provided on the sleeve, and a fourth stopper is provided on the connecting portion. The third and fourth stoppers fit together to limit the rotation angle of the connecting portion.

[0036] In the above proposed technology, a third stopper portion and a fourth stopper portion are installed correspondingly on the sleeve and the connection portion, respectively. The third stopper portion and the fourth stopper portion can be fitted together to limit the rotation angle of the connection portion. As a result, the connection portion can be locked to the locking portion and released from the locking base by the fitting restriction of the third stopper portion and the fourth stopper portion. This facilitates switching between the locked and unlocked states of the locking member, results in a simple structure and easy operation, and mitigates the phenomenon where the locking portion cannot be locked to the locking base because the angle of rotation of the locking portion together with the connection portion is too large. This is advantageous in improving the reliability of mutual locking between the locking mechanism and the locking base.

[0037] In some embodiments, the third and fourth stopper portions are further configured to cooperate in guiding the connecting portion to move along the first direction as the adjusting member rotates relative to the sleeve, so that the locking member moves between a first position and a second position along the first direction, and when the locking member is in the first position, the locking member is in a locked state, allowing the locking portion to engage with the lock base, and when the locking member is in the second position, the locking member is in an unlocked state, allowing the locking portion to release from the lock base.

[0038] In the above proposed technology, the third stopper portion and the fourth stopper portion cooperate to limit the rotation angle of the connection portion and guide the connection portion to move in the first direction relative to the sleeve, thereby enabling the adjustment member to rotate the connection portion relative to the sleeve and simultaneously move the locking member between the first and second positions along the first direction. As a result, the adjustment member can lock the locking portion to the locking base and simultaneously bring the locking portion and the locking base into contact with each other, thereby reducing the size of the gap between the locking portion and the locking base, and further reducing the vibration phenomenon between the locking mechanism and the locking base.

[0039] In some embodiments, the third stopper portion is a stopper groove installed on the inner circumferential surface of the sleeve, and the fourth stopper portion is a projection that protrudes on the outer circumferential surface of the connecting portion, with at least a portion of the projection being housed within the stopper groove.

[0040] In the above proposed technology, the third and fourth stopper parts are a stopper groove installed on the inner circumferential surface of the sleeve and a projection on the outer circumferential surface of the connecting part, respectively. By inserting the projection into the stopper groove, the rotation angle of the connecting part is limited by the restriction of the stopper groove, and the projection is guided by the stopper groove so that the connecting part can rotate relative to the sleeve and move along the first direction relative to the sleeve. The structure is simple, easy to implement, and relatively stable.

[0041] In some embodiments, the stopper groove includes a first groove segment, a second groove segment, and a third groove segment that are sequentially connected, the first groove segment and the third groove segment both extending along a first direction, the first groove segment and the third groove segment being spaced apart along the circumferential direction of the connection, and the first groove segment and the third groove segment being spaced apart along the first direction, the third groove segment being closer to the locking portion than the first groove segment along the first direction, the projection being located within the first groove segment when the locking member is in a first position, and the projection being located within the third groove segment when the locking member is in a second position.

[0042] In the above proposed technology, the first groove segment and the third groove segment of the stopper groove are designed to extend along the first direction, and the first groove segment and the third groove segment are spaced apart in both the first direction and the circumferential direction of the connection. As a result, the second groove segment is a helical groove connected between the first groove segment and the third groove segment. As a result, when the projection of the connection is located within the first groove segment and the third groove segment, it can only move along the first direction along with the extending direction of the first groove segment and the second groove segment, and when the projection of the connection is located within the second groove segment, it can rotate relative to the sleeve along with the extending direction of the second groove segment and move relative to the sleeve along the first direction. This limits the rotation angle of the locking member and allows it to move between the first and second positions along the first direction. Furthermore, by positioning the third groove segment closer to the locking portion in the first direction than the first groove segment, it is possible to lock the locking portion to the lock base when the projection is located within the first groove segment, while simultaneously bringing it closer to the sleeve and enabling the locking portion to come into contact with the lock base in the first direction.

[0043] In some embodiments, the adjustment member includes a connecting segment installed within the sleeve, the connecting segment being fitted onto the outside of the connection portion, and the connecting segment being screwed into the connection portion.

[0044] In the above proposed technology, the adjustment member has a connecting segment, and the connecting segment is screwed onto the outside of the connecting portion to achieve screw engagement between the locking member and the adjustment member. By rotating the adjustment member, the connecting portion can be rotated together with the adjustment member. Furthermore, when the connecting portion is restricted from rotating in the circumferential direction, the adjustment member can provide a transport force to the connecting portion along a first direction, thereby enabling the connecting portion to move in the first direction. The structure is simple and easy to implement.

[0045] In some embodiments, the locking mechanism further includes a locking assembly, which is positioned between the sleeve and the adjustment member, and is used to selectively lock the adjustment member and the sleeve to restrict the adjustment member from rotating relative to the sleeve.

[0046] In the above proposed technology, a loosening prevention assembly is further installed in the locking mechanism. By installing the loosening prevention assembly between the sleeve and the adjustment member, the adjustment member and the sleeve can be selectively locked. That is, when the loosening prevention assembly releases the sleeve and the adjustment member, the loosening prevention assembly can allow the adjustment member to rotate relative to the sleeve. By activating the locking member relative to the sleeve, the locking member can be engaged with or disengaged from the locking base. When the loosening prevention assembly locks the sleeve and the adjustment member, the loosening prevention assembly can restrict the rotation of the adjustment member relative to the sleeve. This mitigates the phenomenon of poor engagement between the locking member and the locking base due to the incorrect rotation of the adjustment member, improving the locking effect between the locking member and the locking base, which is advantageous for improving the stability and reliability of the mutual locking between the locking mechanism and the locking base.

[0047] In some embodiments, the anti-loosening assembly includes a first clutch member and a second clutch member, the first clutch member being mounted on a sleeve and the second clutch member being mounted on an adjustment member, wherein the first and second clutch members are configured to restrict the adjustment member from rotating relative to the sleeve when they are locked together and to allow the adjustment member to rotate relative to the sleeve when they are disengaged from each other.

[0048] In the above proposed technology, the anti-loosening assembly is equipped with a first clutch member and a second clutch member that can lock and engage with each other and disengage from each other, and the first clutch member and the second clutch member are installed on a sleeve and an adjustment member, respectively. As a result, the locking engagement between the first clutch member and the second clutch member restricts the adjustment member from rotating relative to the sleeve, and when the first clutch member and the second clutch member disengage from each other, the adjustment member rotates relative to the sleeve, thereby enabling the anti-loosening assembly to selectively lock the adjustment member and the sleeve.

[0049] In some embodiments, a first clutch member and a second clutch member are arranged along a first direction, where the first clutch member is fixed to a sleeve, the second clutch member and the adjustment member are locked in the circumferential direction, and the second clutch member is movably mounted on the adjustment member along the first direction, thereby allowing the second clutch member to be locked into or disengaged from the first clutch member.

[0050] In the above proposed technology, the first clutch member and the second clutch member are arranged along a first direction, and the second clutch member is movably mounted on the adjustment member along the first direction. By fixing the first clutch member to the sleeve and mounting the second clutch member in a structure that locks circumferentially with the adjustment member, the second clutch member can be moved to achieve locking or disengaging between the second clutch member and the first clutch member, thereby restricting the adjustment member from rotating relative to the sleeve or allowing the adjustment member to rotate relative to the sleeve. Such a locking assembly has a simple structure and is easy to operate and implement.

[0051] In some embodiments, the adjustment member includes a guide segment installed within a sleeve, a second clutch member fitted externally to the outside of the guide segment so as to be movable along a first direction, a first circumferential stopper portion provided on the outer circumferential surface of the guide segment, and a second circumferential stopper portion provided on the inner circumferential surface of the second clutch member, the second circumferential stopper portion and the first circumferential stopper portion engaging to achieve circumferential locking between the second clutch member and the adjustment member.

[0052] In the above proposed technology, the adjustment member has a guide segment, and the second clutch member is fitted to the outside of the guide segment so as to be movable along the first direction. A first circumferential stopper portion is provided on the outer circumferential surface of the guide segment, and a second circumferential stopper portion is provided on the inner circumferential surface of the second clutch member that engages with the first circumferential stopper portion. This enables the second clutch member to move along the first direction relative to the adjustment member and to be locked in the circumferential direction.

[0053] In some embodiments, the first circumferential stopper portion is a spline extending along the first direction, and the second circumferential stopper portion is a spline groove that engages with the spline.

[0054] In the above proposed technology, the first circumferential stopper portion and the second circumferential stopper portion are installed on splines and spline grooves extending along the first direction. That is, splines extending along the first direction are installed on the outer circumferential surface of the guide segment of the adjustment member, and spline grooves that engage with the splines are installed on the inner circumferential surface of the second clutch member. This allows the second clutch member to be locked circumferentially to the adjustment member, but also to move along the first direction relative to the adjustment member. This results in a simple structure and relatively high stability.

[0055] In some embodiments, a first tooth profile is provided at the end of the first clutch member toward the second clutch member along a first direction, and a second tooth profile is provided at the end of the second clutch member toward the first clutch member, and the second tooth profile is used to engage with the first tooth profile to achieve a locking fit between the second clutch member and the first clutch member.

[0056] In the above proposed technology, a first tooth profile is provided at the end of the first clutch member facing the second clutch member, and correspondingly, a second tooth profile is provided at the end of the second clutch member facing the first clutch member. This allows the second tooth profile to engage with or disengage from the first tooth profile when the second clutch member moves in the first direction, thereby achieving locking or disengaging of the second clutch member and the first clutch member. When the first and second tooth profiles engage with each other, the first and second clutch members fit together, restricting the rotation of the adjustment member relative to the sleeve. This results in a simple structure and is easy to implement. Furthermore, by providing the structures of the first and second tooth profiles on the first and second clutch members respectively, the difficulty of locking and disengaging the first and second clutch members can be reduced, which is advantageous for mutual locking or disengaging of the first and second clutch members.

[0057] In some embodiments, a first bevel is formed on the end of the first clutch member toward the second clutch member along a first direction, and a second bevel is formed on the end of the second clutch member toward the first clutch member, and the second bevel and the first bevel are matched, with the first tooth profile being positioned on the first bevel and the second tooth profile being positioned on the second bevel.

[0058] In the above proposed technology, a first inclined surface is provided at the end of the first clutch member facing the second clutch member, and the first tooth profile is positioned on the first inclined surface. Correspondingly, a second inclined surface matching the first inclined surface is provided at the end of the second clutch member facing the first clutch member, and the second tooth profile is positioned on the second inclined surface. By adopting this structure, an inclined structure in which the first tooth profile and the second tooth profile match each other can be realized, thereby providing a certain guiding effect and facilitating mutual engagement between the first tooth profile and the second tooth profile.

[0059] In some embodiments, the first inclined surface is a concave surface installed on the first clutch member, and the second inclined surface is a convex surface installed on the second clutch member.

[0060] In the above-described technical proposal, by setting the first inclined surface as a concave surface and the second inclined surface as a convex surface, the second clutch member is inserted into the first clutch member when the second tooth profile of the second clutch member and the first tooth profile of the first clutch member engage. This is advantageous in improving the stability and reliability of the mutual locking between the second clutch member and the first clutch member, and reduces the phenomenon of slippage when the second clutch member locks and engages with the first clutch member.

[0061] In some embodiments, the anti-loosening assembly further includes a second elastic member positioned between the sleeve and the second clutch member, the second elastic member being configured to lock the second clutch member and the first clutch member by driving the second clutch member to move along the first direction toward the first clutch member.

[0062] In the above proposed technology, a second elastic member is further installed in the anti-loosening assembly between the sleeve and the second clutch member. The second elastic member applies a force to the second clutch member in a first direction similar to that of the first clutch member, thereby locking the first and second clutch members together. By adopting an anti-loosening assembly with such a structure, the stability of the locking between the first and second clutch members is further improved, reducing the phenomenon of accidental disengagement of the first and second clutch members. Furthermore, after the second and first clutch members have disengaged from each other, the second elastic member can automatically lock the second and first clutch members together, eliminating the need for manual intervention and making operation and use easier.

[0063] According to a second aspect, embodiments of the present application further provide a battery assembly comprising a battery and the locking mechanism mounted on the battery.

[0064] According to a third aspect, an embodiment of the present application further provides a power-consuming device comprising a locking base and the battery assembly, wherein the locking mechanism is used to bond to or detach from the locking base along a first direction, and the battery is used to provide electrical energy.

[0065] According to a fourth aspect, embodiments of the present application further provide a locking device comprising a locking base and a locking mechanism, the locking mechanism being used to bond to or detach from the locking base along a first direction. [Brief explanation of the drawing]

Clearly, the embodiments described are only some, not all, embodiments of this application. All other embodiments derived from the embodiments of this application without the creative effort of a person skilled in the art are all within the scope of protection of this application.

[0068] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as that commonly understood by those skilled in the art relating to this application. The terms used in the specification of this application are solely for the purpose of describing specific embodiments and are not intended to limit this application. The terms “includes” and “have” and any variations thereof in the description of the specification, claims, and drawings of this application are intended to intentionally cover non-exclusive “includes.” Terms such as “first,” “second,” etc., in the specification, claims, or drawings of this application are not intended to describe a particular order or subordination, but to distinguish different subjects.

[0069] The “Examples” as used in this application mean that certain features, structures, or characteristics described in conjunction with the Examples may be included in at least one Example of this application. The occurrence of this phrase in each location in the specification does not necessarily refer to the same Example, nor does it mean that each Example is mutually exclusive or alternative to the others.

[0070] In the description of this application, unless otherwise specifically defined or limited, the terms “attachment,” “connection,” “connection,” and “installation” should be understood in a broad sense. For example, a fixed connection may be a detachable connection, an integral connection, a direct connection, an indirect connection via an intermediate medium, or internal communication between two elements. A person skilled in the art will be able to understand the specific meaning of these terms in this application depending on the specific circumstances.

[0071] In this application, the terms "and / or" merely describe the relationship between related objects, indicating that three relationships are possible. For example, A and / or B may represent three cases: A alone, a combination of A and B, or B alone. In this application, the character " / " generally indicates that the preceding and succeeding related objects are in an "or" relationship.

[0072] In the embodiments of this application, the same reference numerals represent the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the dimensions such as thickness, length, and width of various components in the embodiments of this application shown in the drawings, as well as the dimensions such as thickness, length, and width of the overall assembly device, are for illustrative purposes only and should not constitute any limitation to this application.

[0073] The term "multiple" as it appears in this application refers to two or more (including two).

[0074] In the embodiments of this application, the battery cell may be a secondary battery, which is a battery cell that can be used continuously by activating the active material through charging after the battery cell has been discharged.

[0075] The battery cell may be a lithium-ion battery, sodium-ion battery, sodium-lithium-ion battery, lithium metal battery, sodium metal battery, lithium-sulfur battery, magnesium-ion battery, nickel-metal hydride battery, nickel-cadmium battery, lead-acid battery, etc., and the embodiments of this application are not limited thereto.

[0076] A battery cell generally includes an electrode assembly. The electrode assembly includes a positive electrode, a negative electrode, and a separator member. During charging and discharging of the battery cell, active ions (e.g., lithium ions) intercept and deintercept as they move back and forth between the positive and negative electrodes. The separator member is placed between the positive and negative electrodes and can prevent short circuits between them while allowing active ions to pass through.

[0077] In some embodiments, the positive electrode may be a positive electrode plate, and the negative electrode may be a negative electrode plate.

[0078] In some embodiments, the electrode assembly further includes a separator member provided between the positive and negative electrodes.

[0079] In some embodiments, the separator member is a separator.

[0080] In some embodiments, the battery cell may include a housing. The housing is used to package components such as electrode assemblies and electrolytes. The housing may be a steel case, an aluminum case, a plastic case (e.g., polypropylene), a composite metal case (e.g., a copper-aluminum composite housing), or an aluminum laminate film.

[0081] For example, a battery cell may be a cylindrical battery cell, a prismatic battery cell, a pouch battery cell, or a battery cell of other shape. A prismatic battery cell includes, but is not limited to, a prismatic housing battery cell, a blade battery cell, or a polygonal prismatic battery. A polygonal prismatic battery is, for example, a hexagonal prismatic battery.

[0082] The batteries referred to in the embodiments of this application refer to a single physical module comprising one or more battery cells to provide higher voltage and capacity.

[0083] In some embodiments, the battery may be a battery module, and if there are multiple battery cells, the multiple battery cells are fixed side by side to form a single battery module.

[0084] In some embodiments, the battery may be a battery pack, which includes a housing and battery cells, and the battery cells or battery modules are housed in the housing.

[0085] With advancements in science and technology, new energy vehicles are developing rapidly, and the market share and frequency of use of electric vehicles are increasing. Electric commercial vehicles, such as electric heavy-duty trucks and electric light-duty trucks, are increasingly appearing in various application scenarios, and substations for replacing the battery assemblies of electric trucks have been constructed accordingly.

[0086] In the new energy vehicle sector, electric trucks have large vehicle loads, long driving ranges, and higher energy consumption than ordinary passenger cars. Therefore, to achieve their range, electric trucks must constantly perform power exchange operations. As part of power exchange, the locking and unlocking of the battery mounted on the vehicle is a key point of interest. To achieve battery locking, the currently mainly adopted method involves installing a lock base on the vehicle, a corresponding locking mechanism on the battery, and using an adjustment member of the locking mechanism to lock or unlock the locking member of the locking mechanism with the lock base, thereby completing the vehicle's power exchange function. However, in locking mechanisms, the locking member and adjustment member are generally screwed together, allowing the adjustment member to move or rotate the locking member. In such locking mechanisms, after repeated power changes, slippage is likely to occur between the locking member and the adjustment member. Furthermore, the gravity of the battery being assembled on the vehicle acts directly on the screw structure between the locking member and the adjustment member, increasing the risk of poor threading between them. As a result, the lifespan of the locking mechanism between the battery and the vehicle is relatively short, and its reliability is relatively low. Consequently, power changes for power-consuming devices are inconvenient, raising safety concerns.

[0087] Based on the above considerations, in order to solve technical problems such as the relatively short service life and relatively low reliability of the locking mechanism between the battery and the vehicle, an embodiment of the present application provides a locking mechanism comprising a sleeve, a locking member, an adjustment member, and a fastening assembly. The locking member is movably mounted in the sleeve and has a locked state and an unlocked state, and is configured to bond the locking mechanism and the locking base along a first direction by engaging with the locking base when in the locked state, and is configured to release from the locking base when in the unlocked state, allowing the locking mechanism and the locking base to detach in the first direction. The adjustment member is rotatably connected in the sleeve about an axis extending along the first direction, and is screwed onto the locking member, and is configured to switch the locking member between a locked state and an unlocked state by activating the locking member relative to the sleeve when the adjustment member rotates relative to the sleeve. The clamping assembly is configured such that, when the locking member is in the locked position, the locking member prevents the adjusting member from moving in the first direction toward the locking base.

[0088] In a locking mechanism of this structure, a locking member and an adjustment member are installed in the locking mechanism, and by screwing the locking member and the adjustment member together, the locking member is activated relative to the sleeve when the adjustment member is rotated, thereby enabling the locking member to be switched between a locked state and an unlocked state. This allows the locking mechanism and the locking base to be bonded or detached along a first direction by engaging or disengaging the locking member from the locking base. By installing a tightening assembly on the locking mechanism, the tightening assembly can prevent the locking member from moving relative to the adjusting member in the direction toward the lock base when the locking member is in the locked state. In other words, when the locking member engages with the lock base and the locking mechanism and lock base are bonded in the first direction, the locking member and adjusting member can be further locked by the action of the tightening assembly. This prevents the locking member from moving toward the lock base relative to the adjusting member, further preventing the locking member from detaching from the adjusting member in the first direction. By adopting a locking mechanism with such a structure, the risk of the locking member and adjusting member detaching from each other when the locking member and lock base engage with each other can be further reduced, improving the stability and reliability of the mutual locking between the locking mechanism and the lock base. At the same time, the tightening assembly can transfer the force applied to the screw structure between the locking member and the adjusting member to the tightening assembly, thereby mitigating the phenomenon of damage to the sliding teeth or screw structure between the locking member and the adjusting member, reducing the risk of poor threading between the locking member and the adjusting member, and further improving the service life and reliability of the locking mechanism.

[0089] The locking mechanism disclosed in the embodiments of this application may be used in, but is not limited to, power-consuming equipment such as vehicles, ships, or aircraft. The locking mechanism, battery assembly, etc. disclosed in this application can be used to configure a power supply system for such power-consuming equipment, which is advantageous in mitigating problems such as the relatively short service life and relatively low reliability of the locking mechanism, and improving the safety of use of the power-consuming equipment.

[0090] Embodiments of this application provide power-consuming devices that use a battery assembly as a power source, which may be, but are not limited to, mobile phones, tablets, laptops, electric toys, power tools, battery cars, electric vehicles, steamships, and aerospace aircraft. Here, electric toys may include stationary or mobile electric toys, such as game consoles, electric car toys, electric steamship toys and electric airplane toys, and aerospace aircraft may include airplanes, rockets, space shuttles and spacecraft.

[0091] For the sake of explanation, the following embodiments will be described using the example that the power-consuming device in one embodiment of this application is a vehicle.

[0092] Referring to Figure 1, Figure 1 is a schematic diagram of the structure of a vehicle 1000 according to some embodiments of the present application. The vehicle 1000 may be a fuel oil vehicle, a gas vehicle, or a new energy vehicle, and the new energy vehicle may be a pure electric vehicle, a hybrid vehicle, or a range extender vehicle. A battery assembly 100 is installed inside the vehicle 1000, and the battery assembly 100 may be installed at the bottom of the vehicle 1000, at the front of the vehicle 1000, or at the rear of the vehicle 1000.

[0093] Referring to Figures 2 and 3, which are part of some embodiments of this application, Figure 2 is a schematic diagram of the local structure of vehicle 1000 according to some embodiments of this application, and Figure 3 is an exploded view of the local structure of vehicle 1000 according to some embodiments of this application. Vehicle 1000 has a mounting frame 200 and a lock base 300, the lock base 300 is mounted on the mounting frame 200, and a battery assembly 100 includes a lock mechanism 10 and a battery 20, the lock mechanism 10 is mounted on the battery 20, and the lock mechanism 10 is used to lock or unlock with the lock base 300 to enable power exchange of vehicle 1000. The battery 20 may also be used to supply power to vehicle 1000, for example, the battery 20 can be the operating power or the power source of vehicle 1000.

[0094] Selectively, referring to Figure 1, the vehicle 1000 may further include a controller 400 and a motor 500, the controller 400 being used to control the battery 20 to supply power to the motor 500, for example, to meet the operating power consumption requirements for starting, navigating, and driving the vehicle 1000.

[0095] In some embodiments of this application, the battery 20 can provide driving power to the vehicle 1000 not only as an operating power source or power source for the vehicle 1000, but also as a driving power source for the vehicle 1000, in place of or in part of fuel oil or natural gas.

[0096] Referring to Figure 3, and further to Figure 4, Figure 4 is an exploded view of the structure of a battery 20 according to some embodiments of the present application. The battery 20 may include a housing 21 and battery cells 22, the battery cells 22 being used to be housed within the housing 21, and the locking mechanism 10 being mounted on the housing 21.

[0097] Here, the housing 21 is used to provide assembly space for the battery cell 22, and the housing 21 can employ various structures. In some embodiments, the housing 21 may include a first housing body 211 and a second housing body 212, the first housing body 211 and the second housing body 212 overlap each other, and the first housing body 211 and the second housing body 212 together define the assembly space for housing the battery cell 22. Both the first housing body 211 and the second housing body 212 may have a hollow structure with one side open, and the open side of the first housing body 211 overlaps the open side of the second housing body 212, thereby defining the assembly space for both the first housing body 211 and the second housing body 212. Exemplarily, the locking mechanism 10 may be mounted on the first housing body 211 or on the second housing body 212.

[0098] In other embodiments, the housing 21 may have other structures. For example, the second housing body 212 may be a hollow structure with one end open, and the first housing body 211 may be a plate-like structure. The first housing body 211 is placed over the open side of the second housing body 212, thereby limiting the assembly space for both the first housing body 211 and the second housing body 212. Of course, the housing 21 formed by the first housing body 211 and the second housing body 212 may have various shapes, such as a cylinder or a rectangular parallelepiped. Exemplarily, in Figure 4, the shape of the housing 21 is a rectangular parallelepiped.

[0099] In the battery 20, the battery cells 22 installed in the housing 21 may be one or multiple. If there are multiple battery cells 22 installed in the housing 21, the multiple battery cells 22 may be connected in series, in parallel, or in series-parallel connection, where series-parallel connection means that among the multiple battery cells 22, both series and parallel connections are present. The multiple battery cells 22 may be directly connected in series, in parallel, or in series-parallel, and then the entire assembly composed of the multiple battery cells 22 may be housed in the housing 21. Of course, the battery 20 may first have multiple battery cells 22 connected in series, in parallel, or in series-parallel to form a battery module, and then the multiple battery modules may be connected in series, in parallel, or in series-parallel to form the whole, which may then be housed in the housing 21. In some embodiments, the battery 20 may further include other structures, for example, the battery 20 may further include a busbar member which is connected to a plurality of battery cells 22 and used to realize electrical connections between the plurality of battery cells 22.

[0100] Here, each battery cell 22 may be a secondary battery or a primary battery, and may be, but is not limited to, a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery. The battery cell 22 may have a cylindrical, flattened, rectangular parallelepiped, or other shape. Exemplarily, in Figure 4, the battery cell 22 has a rectangular parallelepiped structure.

[0101] According to some embodiments of this application, referring to Figure 3, and further to Figures 5, 6 and 7, Figure 5 is a schematic diagram of the structure of a locking mechanism 10 according to some embodiments of this application, Figure 6 is an exploded view of the structure of a locking mechanism 10 according to some embodiments of this application, and Figure 7 is a cross-sectional view of a locking mechanism 10 according to some embodiments of this application (when the locking member 12 is in the locked state). This application provides a locking mechanism 10 for bonding or detaching a locking base 300 along a first direction X, the locking mechanism 10 comprising a sleeve 11, a locking member 12, an adjustment member 13, and a fastening assembly 14. The locking member 12 is movably mounted on the sleeve 11 and has a locked state and an unlocked state. When in the locked state, the locking member 12 engages with the lock base 300, thereby bonding the locking mechanism 10 and the lock base 300 along a first direction X. When in the unlocked state, the locking member 12 releases its engagement with the lock base 300, allowing the locking mechanism 10 and the lock base 300 to detach along the first direction X. The adjustment member 13 is rotatably connected within the sleeve 11 around an axis extending along the first direction X. The adjustment member 13 screws into the locking member 12 and is configured to switch the locking member 12 between the locked state and the unlocked state by activating the locking member 12 relative to the sleeve 11 when the adjustment member 13 rotates relative to the sleeve 11. The fastening assembly 14 is configured such that when the locking member 12 is in the locked state, the locking member 12 prevents the adjustment member 13 from moving in the direction toward the lock base 300 in the first direction X.

[0102] Here, the locking member 12 plays a role in locking or releasing the lock base 300, thereby bonding or detaching the locking mechanism 10 from the lock base 300 via the locking member 12 along the first direction X, and achieving locking or unlocking between the locking mechanism 10 and the lock base 300.

[0103] The locking member 12 can act relative to the sleeve 11, thereby having a locked state in which it engages with the lock base 300 and a released state in which it can release from the lock base 300. The structure of the locking member 12 may vary; for example, in Figures 6 and 7, the locking member 12 includes a connecting portion 121 and a locking portion 122, the connecting portion 121 extending along a first direction X and inserted into the sleeve 11, the connecting portion 121 screwing into the adjustment member 13, the locking portion 122 located outside the sleeve 11 and connected to the end of the connecting portion 121 away from the sleeve 11, the locking portion 122 along its extending direction relative to the outer circumferential surface of the connecting portion 121 The protruding locking portion 122 is used to lock with the lock base 300, and the direction of extension of the locking portion 122 is perpendicular to the first direction X. By making the locking member 12 rotatable around an axis extending in the first direction X and having an irregular structure, it is possible to rotate the locking portion 122 by rotating the connecting portion 121, thereby enabling the locking portion 122 to lock or release from the lock base 300. Of course, in other embodiments, the locking member 12 may have a structure that is extendable and retractable in a direction perpendicular to the first direction X, thereby enabling the locking member 12 to lock or release from the lock base 300.

[0104] The adjustment member 13 is screwed into the locking member 12, that is, the locking member 12 is screwed into the adjustment member 13, and the locking member 12 may be inserted into the adjustment member 13, the locking member 12 has an external thread, the adjustment member 13 has an internal thread, and the locking member 12 is screwed into the adjustment member 13. Alternatively, the adjustment member 13 may be inserted into the locking member 12, the locking member 12 has an internal thread, the adjustment member 13 has an external thread, and the locking member 12 is screwed into the adjustment member 13. Exemplarily, in Figure 7, the connecting portion 121 of the locking member 12 is inserted into the adjustment member 13, the connecting portion 121 has an external thread, and the adjustment member 13 has an internal thread, thereby achieving screwing the adjustment member 13 and the locking member 12.

[0105] The adjustment member 13 is configured to activate the locking member 12 relative to the sleeve 11 when it rotates relative to the sleeve 11, thereby enabling the locking member 12 to switch between a locked state and an unlocked state. In other words, by rotating the adjustment member 13 relative to the sleeve 11, the adjustment member 13 activates the locking member 12 relative to the sleeve 11, enabling the locking member 12 to switch between a locked state and an unlocked state. For example, in Figure 7, by rotating the adjustment member 13, the connecting portion 121 of the locking member 12 rotates the locking portion 122, causing the locking portion 122, whose extending direction is perpendicular to the first direction X, to rotate in a plane perpendicular to the first direction X. As a result, the locking portion 122 can engage with or disengage from the lock base 300, enabling the locking member 12 to switch between a locked state and an unlocked state.

[0106] The fastening assembly 14 is configured to prevent the locking member 12 from moving relative to the adjustment member 13 in the direction toward the lock base 300 when the locking member 12 is in the locked state, that is, when the locking member 12 is engaged with the lock base 300, the fastening assembly 14 can restrict the locking member 12 from moving in the direction toward the locking portion 122 from the sleeve 11 in the first direction X.

[0107] The locking mechanism 10 is equipped with a locking member 12 and an adjustment member 13. By screwing the locking member 12 and the adjustment member 13 together, the locking member 12 is activated relative to the sleeve 11 when the adjustment member 13 is rotated, thereby enabling the locking member 12 to switch between a locked state and an unlocked state. This allows the locking member 12 to engage with or disengage from the locking base 300, thereby enabling the locking mechanism 10 and the locking base 300 to adhere to or detach along the first direction X. By installing the tightening assembly 14 on the locking mechanism 10, the tightening assembly 14 can prevent the locking member 12 from moving relative to the adjustment member 13 in the direction toward the lock base 300 in the first direction X when the locking member 12 is in the locked state. In other words, when the locking member 12 engages with the lock base 300 and the locking mechanism 10 and the lock base 300 are bonded together in the first direction X, the locking member 12 and the adjustment member 13 can be further locked by the action of the tightening assembly 14. This prevents the locking member 12 from moving toward the lock base 300 relative to the adjustment member 13, and prevents the locking member 12 from detaching from the adjustment member 13 in the first direction X. Furthermore, by preventing this and adopting a locking mechanism 10 with such a structure, the risk of the locking member 12 and the adjustment member 13 separating from each other when the locking member 12 and the locking base 300 engage with each other can be further reduced, improving the stability and reliability of the mutual locking between the locking mechanism 10 and the locking base 300. At the same time, the force applied to the screw structure between the locking member 12 and the adjustment member 13 can be transferred to the tightening assembly 14 by the tightening assembly 14, thereby mitigating the phenomenon of damage to the sliding teeth or screw structure between the locking member 12 and the adjustment member 13, reducing the risk of poor threading between the locking member 12 and the adjustment member 13, and further benefiting from improving the service life and reliability of the locking mechanism 10.

[0108] According to some embodiments of this application, referring to Figures 6 and 7, and further to Figure 8, Figure 8 is a local enlarged view of A of the locking mechanism 10 shown in Figure 7. A clamping assembly 14 is installed on the locking member 12, and an adjustment member 13 has a contact surface 131, and the clamping assembly 14 is configured such that when the locking member 12 is in a locked state, the adjustment member 13 contacts the contact surface 131 in a first direction X toward the locking base 300.

[0109] Here, the locking member 12 has a mounting portion 123 that is inserted into the adjustment member 13, the mounting portion 123 having a connecting portion 121 connected to the end away from the locking portion 122 in a first direction X, and the tightening assembly 14 is mounted on the mounting portion 123 of the locking member 12. Of course, in other embodiments, the tightening assembly 14 may be mounted on the adjustment member 13, and accordingly, the locking member 12 is provided with a contact portion that contacts the tightening assembly 14.

[0110] The adjustment member 13 has a contact surface 131, which is formed on the inner surface of the adjustment member 13. That is, the inner surface of the adjustment member 13 includes the contact surface 131. Exemplarily, in Figure 8, the contact surface 131 is an arc-shaped surface formed on the inner surface of the adjustment member 13. Of course, in other embodiments, the contact surface 131 may be an inclined plane placed on the adjustment member 13.

[0111] It should be noted that in other embodiments, the locking mechanism 10 may have a different structure. For example, a portion of the adjustment member 13 may be inserted into the locking member 12, and correspondingly, the contact surface 131 may be formed on the outer surface of the adjustment member 13.

[0112] The fastening assembly 14 is mounted on the locking member 12, and the adjustment member 13 has a contact surface 131 that abuts against the fastening assembly 14. This allows the fastening assembly 14 to abut against the contact surface 131 in the direction in which the adjustment member 13 moves toward the lock base 300 in a first direction X when the locking member 12 is in the locked state, thereby preventing the locking member 12 from moving toward the adjustment member 13 in the direction in which the adjustment member 13 moves toward the lock base 300 in a first direction X. This transfers the force on the screw structure between the locking member 12 and the adjustment member 13 between the fastening assembly 14 and the contact surface 131 of the adjustment member 13, mitigating the phenomenon of damage to the sliding teeth or screw structure between the locking member 12 and the adjustment member 13.

[0113] According to some embodiments of this application, with reference to Figures 6, 7 and 8, the locking member 12 has a mounting portion 123 inserted into the adjustment member 13 along a first direction X, and the inner surface of the adjustment member 13 includes a contact surface 131. The fastening assembly 14 includes a locking member 141, which is movably mounted in the mounting portion 123, and is used to protrude from the outer circumferential surface of the mounting portion 123 and then contact the contact surface 131, or to return to the mounting portion 123 and then release from contact with the contact surface 131.

[0114] Here, the inner surface of the adjustment member 13 includes the contact surface 131, that is, the contact surface 131 is formed on the inner surface of the adjustment member 13.

[0115] The locking member 141, after contacting the contact surface 131, prevents the locking member 12 from moving relative to the adjustment member 13 in a first direction X toward the lock base 300. The locking member 141 is movably mounted on the mounting portion 123 and is used to contact the contact surface 131 after protruding from the outer circumferential surface of the mounting portion 123, or to release contact with the contact surface 131 after returning to the mounting portion 123. In other words, when the locking member 141 moves relative to the mounting portion 123 and protrudes from the outer circumferential surface of the mounting portion 123, it can contact the contact surface 131 of the adjustment member 13, preventing the locking member 12 from moving relative to the adjustment member 13. Conversely, when the locking member 141 moves relative to the mounting portion 123 and retracts into the mounting portion 123, it can release contact with the contact surface 131 of the adjustment member 13, allowing the locking member 12 to move relative to the adjustment member 13.

[0116] For example, in Figure 8, a mounting hole 1231 is provided on the outer circumferential surface of the mounting portion 123, and a locking member 141 is installed so as to be movable within the mounting hole 1231 along the radial direction of the mounting portion 123, thereby allowing the locking member 141 to protrude from the outer circumferential surface of the mounting portion 123 or to retract into the mounting portion 123 when moving along the radial direction of the mounting portion 123.

[0117] It should be noted that in other embodiments, the structure of the clamping assembly 14 may vary. For example, the clamping assembly 14 may be a locking pin inserted between the locking member 12 and the adjustment member 13. When the locking member 12 is in the locked state, the locking pin is inserted between the locking member 12 and the adjustment member 13 along the radial direction of the locking member 12, thereby preventing the locking member 12 from moving relative to the adjustment member 13 in the direction toward the lock base 300 in a first direction X.

[0118] The locking member 12 has a mounting portion 123 that is inserted inside the adjustment member 13, and its contact surface 131 is located on the inner surface of the adjustment member 13. This allows the locking member 141 of the tightening assembly 14 to protrude from the outer circumferential surface of the mounting portion 123 and then contact the contact surface 131, thereby preventing the tightening assembly 14 from moving in the direction toward the lock base 300 in the first direction X relative to the adjustment member 13. Conversely, by releasing the contact surface 131 after the locking member 141 of the tightening assembly 14 returns to the mounting portion 123, the locking member 12 can be made to move relative to the adjustment member 13, resulting in a simple structure and easy implementation.

[0119] Referring to several embodiments of this application, with reference to Figures 6, 7 and 8, and further to Figure 9, Figure 9 is a cross-sectional view of a locking mechanism 10 (when the locking member 12 is in an unlocked state) according to several embodiments of this application. The fastening assembly 14 may further include a movable member 142, which is movably installed within the mounting portion 123 along a first direction X, and is configured to cause the locking member 141 to contact or release the contact surface 131 by pushing the locking member 141 so that it protrudes from the outer circumferential surface of the mounting portion 123 when moved relative to the mounting portion 123 along the first direction X, or by allowing the locking member 141 to return to within the mounting portion 123.

[0120] Here, the movable member 142 plays the role of pushing the locking member 141 so that it protrudes from the outer circumferential surface of the mounting portion 123, or allowing the locking member 141 to return to the mounting portion 123. For explanation purposes, referring to Figure 8, when the movable member 142 moves along the first direction X toward the connection portion 121 of the locking member 12, the movable member 142 moves the locking member 141 relative to the mounting portion 123 along the radial direction of the mounting portion 123, pushing it so that it protrudes from the outer circumferential surface of the mounting portion 123. This enables the locking member 141 and the contact surface 131 to come into contact with each other, locking the locking member 141 in a position where it comes into contact with the contact surface 131, and when the moving member 142 moves in the direction away from the connection portion 121 of the locking member 12 along the first direction X, the moving member 142 can release the restraint on the locking member 141, thereby enabling the locking member 141 to return to the mounting portion 123 due to the reaction force of the contact surface 131, and the locking member 141 to release the contact with the contact surface 131.

[0121] The fastening assembly 14 is equipped with a movable member 142 that pushes the locking member 141 so that it protrudes from the outer circumferential surface of the mounting portion 123, and allows the locking member 141 to return to the mounting portion 123. By positioning the movable member 142 to be movable within the mounting portion 123 along a first direction X, when the movable member 142 moves relative to the mounting portion 123 in one direction of the first direction X, the locking member 141 is pushed so that it protrudes from the outer circumferential surface of the mounting portion 123, preventing the locking member 141 from returning. At the same time, when the movable member 142 moves relative to the mounting portion 123 in another direction of the first direction X, contact with the locking member 141 is released, allowing the locking member 141 to return to the mounting portion 123. This enables the locking member 141 to contact or release contact with the contact surface 131.

[0122] According to some embodiments of this application, referring to Figures 6, 7, 8, and 9, the adjustment member 13 is configured such that when it rotates relative to the sleeve 11, it can move the locking member 12 along a first direction X between a first position and a second position, and when the locking member 12 is in the first position (as shown in Figure 7), the locking member 12 is in a locked state, and when the locking member 12 is in the second position (as shown in Figure 9), the locking member 12 is in an unlocked state. The adjustment member 13 is provided with an execution part 132 which contacts the moving member 142 when the locking member 12 moves from the second position to the first position and can push the moving member 142 to move, thereby pushing the locking member 141 out of the outer circumferential surface of the mounting part 123, and can separate from the moving member 142 when the locking member 12 moves from the first position to the second position, thereby allowing the moving member 142 to return to the mounting part 123.

[0123] Here, the adjustment member 13 is equipped with an execution unit 132, and when the adjustment member 13 rotates relative to the sleeve 11, the execution unit 132 can push the moving member 142 along the first direction X toward the connection unit 121 when the locking member 12 moves from the second position to the first position (switching from the structure shown in Figure 9 to the structure shown in Figure 7), thereby pushing the locking member 141 so that it protrudes from the outer circumferential surface of the mounting unit 123, so that the locking member 141 can come into contact with the contact surface 131, and the execution unit 132 can further perform the following roles. When the adjustment member 13 rotates relative to the sleeve 11, the locking member 12 moves from the first position to the second position (switching from the structure shown in Figure 7 to the structure shown in Figure 9). By allowing the moving member 142 to move away from the connecting portion 121 along the first direction X, the constraint on the locking member 141 is released, allowing the locking member 141 to return to the mounting portion 123, thereby releasing the locking member 141 from contact with the contact surface 131.

[0124] Illustratively, referring to Figures 6 and 8, a mounting channel 133 is provided at the end of the adjustment member 13 away from the locking portion 122 of the locking member 12, and the execution portion 132 is housed within the mounting channel 133 and fixedly connected to the adjustment member 13. Correspondingly, a housing cavity 1232 is provided inside the mounting portion 123, and the housing cavity 1232 communicates with the mounting channel 133 by passing through the end of the mounting portion 123 away from the locking portion 122 in a first direction X, and the housing cavity 1232 also communicates with a mounting hole 1231 installed on the outer circumferential surface of the mounting portion 123, and the movable member 142 is installed to be movable within the housing cavity 1232 along the first direction X, and the execution portion 132 and the locking member 12 are arranged along the first direction X, thereby moving the locking member 12 from a second position to a first position. When the locking member 12 moves, that is, when the locking member 12 moves in the first direction X toward the execution part 132, the portion of the execution part 132 is inserted into the housing cavity 1232 and comes into contact with the moving member 142 (as shown in Figure 7), pushing the moving member 142 toward the connection part 121 along the first direction X. Conversely, when the locking member 12 moves from the first position to the second position, that is, when the locking member 12 moves in the first direction X toward the execution part 132, the execution part 132 can retract from the housing cavity 1232 and separate from the moving member 142 (as shown in Figure 9), thereby enabling the moving member 142 to move toward the connection part 121 along the first direction X, allowing the locking member 141 to come into contact with or release the contact surface 131 by the execution part 132.

[0125] Selectively, the connection method between the execution unit 132 and the adjustment member 13 may vary. For example, the execution unit 132 may be screwed into the adjustment member 13, welded to the adjustment member 13, or connected to the inner wall surface of the mounting channel 133 by interference fit.

[0126] The adjustment member 13 allows the locking member 12 to be switched between a locked state and an unlocked state, and at the same time moves the locking member 12 along a first direction X relative to the sleeve 11, so that the locking member 12 has a first position and a second position in the first direction X. By installing the execution unit 132 on the adjustment member 13, the execution unit 132 can contact the moving member 142 when the locking member 12 moves from the second position to the first position and push the moving member 142 to move, thereby causing the locking member 141 to protrude from the outer circumferential surface of the mounting portion 123 by the pushing of the moving member 142, and the execution unit 132 can further contact the moving member 142 when the locking member 12 moves from the first position to the second position. By separating them, the constraint of the execution unit 132 on the moving member 142 can be released, thereby allowing the moving member 142 to allow the locking member 141 to return to the mounting part 123. This allows the locking member 12 to be switched between a locked state and an unlocked state by moving the locking member 12 along the first direction X, while at the same time, the locking member 141 of the fastening assembly 14 protrudes from the outer surface of the mounting part 123 due to the engagement between the moving member 142 and the execution unit 132, or allows the locking member 141 of the fastening assembly 14 to return to the mounting part 123, thereby realizing the interlocking of the locking mechanism 10. This eliminates the need for an additional drive mechanism or manual intervention, which is advantageous in reducing the difficulty of operating the locking mechanism 10.

[0127] According to some embodiments of this application, with reference to Figures 8 and 9, the execution portion 132 and the mounting portion 123 are arranged along a first direction X, and a projection 1321 is provided at the end of the execution portion 132 facing the mounting portion 123, and the projection 1321 is configured to be inserted into the mounting portion 123 and to contact the movable member 142.

[0128] Here, along the first direction X, the protrusion 1321 is provided on the end of the execution unit 132 facing the locking member 12, and the protrusion 1321 is inserted into the housing cavity 1232 and comes into contact with the movable member 142, enabling the execution unit 132 to push and move the movable member 142.

[0129] By installing a protrusion 1321 at the end of the execution portion 132 facing the mounting portion 123 along the first direction X, the protrusion 1321 can be inserted into the mounting portion 123 and come into contact with the movable member 142 when the mounting portion 123 is close to the execution portion 132 along the first direction X, thereby improving the effect of the execution portion 132 pushing the movable member 142 to move.

[0130] In some embodiments, referring to Figure 8, a housing cavity 1232 is formed inside the mounting portion 123, the housing cavity 1232 penetrates the end of the mounting portion 123 near the execution portion 132 along a first direction X, and the housing cavity 1232 is for the insertion of the protrusion 1321. A movable member 142 is installed to be movable within the housing cavity 1232 along the first direction X, and a mounting hole 1231 is provided on the outer circumferential surface of the mounting portion 123, the mounting hole 1231 communicates with the housing cavity 1232, and the locking member 141 is installed to be movable within the mounting hole 1231.

[0131] By installing a housing cavity 1232 inside the mounting portion 123 for housing the movable member 142, and by having the housing cavity 1232 penetrate one end of the mounting portion 123 along the first direction X, the protrusion 1321 of the execution portion 132 is easily inserted into the housing cavity 1232, thereby enabling mutual contact between the protrusion 1321 and the movable member 142, which is advantageous in simplifying the structural complexity of the locking mechanism 10. Furthermore, a mounting hole 1231 communicating with the housing cavity 1232 is provided on the outer circumferential surface of the mounting portion 123, and the locking member 141 is movably installed within the mounting hole 1231. This allows the locking member 141 to be pushed outwards from the outer circumferential surface of the mounting portion 123 via the mounting hole 1231 when the movable member 142 moves along the first direction X within the housing cavity 1232, or allows the third locking portion 122 to return to the mounting portion 123 via the mounting hole 1231, resulting in a simple structure and easy implementation.

[0132] According to some embodiments of this application, with reference to Figure 8, the clamping assembly 14 may further include a first elastic member 143 positioned between the movable member 142 and the mounting portion 123, the first elastic member 143 being configured such that the movable member 142 moves along a first direction X toward the execution portion 132, thereby allowing the locking member 141 to return to the mounting portion 123.

[0133] Here, the first elastic member 143 is configured to drive the moving member 142 in a direction closer to the execution unit 132 along the first direction X, that is, the first elastic member 143 can apply an elastic force to the moving member 142 in the direction closer to the execution unit 132 along the first direction X.

[0134] Exemplary, in Figure 8, the first elastic member 143 is connected between the movable member 142 and the cavity bottom surface of the housing cavity 1232 in a compressed state in the first direction X. Of course, in other embodiments, the first elastic member 143 may be connected between the movable member 142 and the end of the mounting portion 123 away from the connection portion 121 in a stretched state along the first direction X.

[0135] For example, in Figure 8, the first elastic member 143 is a spring, and in other embodiments, the first elastic member 143 may be an elastic sheet or elastic rubber installed between the movable member 142 and the mounting portion 123.

[0136] A first elastic member 143 is further installed between the movable member 142 and the mounting portion 123. The first elastic member 143 can apply a force to the movable member 142 in a direction closer to the execution portion 132 along the first direction X. This allows the movable member 142 to automatically return to a position that allows the locking member 141 to return to the mounting portion 123 after it has separated from the execution portion 132. This mitigates the phenomenon where the contact surface 131 of the locking member 141 and the adjustment member 13 accidentally come into contact due to the movable member 142 being unable to return, while also making operation and use easier without requiring human intervention.

[0137] According to some embodiments of this application, referring to Figures 6 and 8, a first stopper portion 1233 is installed inside the mounting portion 123, and a second stopper portion 1421 is installed on the movable member 142. The first stopper portion 1233 and the second stopper portion 1421 are fitted together to limit the range in which the movable member 142 moves relative to the mounting portion 123 in a first direction X.

[0138] Here, the first stopper portion 1233 and the second stopper portion 1421 are provided on the mounting portion 123 and the movable member 142, respectively. The first stopper portion 1233 and the second stopper portion 1421 fit together to limit the range of movement of the movable member 142 in the first direction X. The structures of the first stopper portion 1233 and the second stopper portion 1421 can vary. For example, the first stopper portion 1233 may be a stopper block installed on the inner surface of the mounting portion 123. Correspondingly, the second stopper portion 1421 is a groove installed on the outer circumferential surface of the movable member 142, and at least a part of the stopper block is inserted into the groove. Of course, the first stopper portion 1233 may be a strip-shaped hole installed on the inner surface of the mounting portion 123, the longitudinal direction of the strip-shaped hole is the first direction X, and correspondingly, the second stopper portion 1421 is a plug protruding from the outer circumferential surface of the mounting portion 123, and at least a part of the plug is inserted into the strip-shaped hole.

[0139] A first stopper portion 1233 and a second stopper portion 1421 are installed on the mounting portion 123 and the movable member 142, respectively. The fitting of the first stopper portion 1233 and the second stopper portion 1421 allows the movable member 142 to be restricted in the range of movement of the movable member 142 in the first direction X relative to the mounting portion 123. This enables the movable member 142 to accurately switch between a position in which it pushes the locking member 141 so that it protrudes from the outer circumferential surface of the mounting portion 123 and a position that allows the locking member 141 to return to inside the mounting portion 123. This is advantageous for improving the accuracy of the locking member 141 contacting and releasing the contact surface 131, while also providing a certain stopper action to the movable member 142, reducing the risk of the movable member 142 detaching from the mounting portion 123.

[0140] In some embodiments, referring to Figure 8 and further to Figure 10, Figure 10 is a cross-sectional view of a movable member 142 of a fastening assembly 14 of a locking mechanism 10 according to some embodiments of the present application. The first stopper portion 1233 is a stopper block installed on the inner circumferential surface of the mounting portion 123, and the second stopper portion 1421 is a groove installed on the outer circumferential surface of the movable member 142, wherein at least a portion of the stopper block is housed in the groove.

[0141] Here, at least a portion of the stopper block is housed in the groove; that is, the entire stopper block may be housed in the groove, or only a portion of it may be housed in the groove.

[0142] For example, the stopper block is locked in a mounting groove on the inner circumferential surface of the mounting portion 123. Of course, in other embodiments, the stopper block may be connected to the inner circumferential surface of the mounting portion 123 by welding, adhesive, or interference fit.

[0143] In other embodiments, the groove may be installed on the inner circumferential surface of the mounting portion 123, and accordingly, the stopper block is provided as a protrusion on the outer circumferential surface of the movable member 142.

[0144] It should be explained that in embodiments in which a first elastic member 143 is further installed between the movable member 142 and the mounting portion 123, the first elastic member 143 may be installed between the side of the stopper block facing the connection portion 121 in the first direction X and the groove side wall of the recessed groove.

[0145] The first stopper portion 1233 and the second stopper portion 1421 are a stopper block installed on the inner circumferential surface of the mounting portion 123 and a groove installed on the outer circumferential surface of the movable member 142, respectively. By inserting the stopper block into the groove, when the movable member 142 moves relative to the mounting portion 123, the stopper block comes into contact with the two groove side walls that face the first direction X, and the fitting of the stopper block and the groove can limit the range of movement of the movable member 142 in the first direction X. This structure is simple, easy to implement, and relatively stable.

[0146] In some embodiments, referring to Figures 6, 8, and 10, the first stopper portion 1233 is an annular stopper block extending along the circumferential direction of the movable member 142, and the second stopper portion 1421 is an annular groove extending along the circumferential direction of the movable member 142.

[0147] By installing both the first stopper portion 1233 and the second stopper portion 1421 in an annular structure, it is advantageous to further improve the stability and reliability of limiting the movable member 142 by fitting together the first stopper portion 1233 and the second stopper portion 1421.

[0148] According to some embodiments of this application, referring to Figures 8 and 10, a guide slope 1422 is formed on the movable member 142, which contacts the locking member 141 and pushes the locking member 141 to protrude from the outer circumferential surface of the mounting portion 123.

[0149] Here, the guide slope 1422 is formed at the end of the movable member 142 that is closer to the connection portion 121 in the first direction X. Exemplarily, the end of the movable member 142 that is closer to the connection portion 121 in the first direction X has a conical structure, thereby forming a conical surface at the end of the movable member 142 that is closer to the connection portion 121 in the first direction X. This conical surface is the guide slope 1422, and thereby, when the movable member 142 moves along the first direction X in the direction closer to the connection portion 121, the locking member 141 can protrude from the outer circumferential surface of the mounting portion 123 by the pushing motion of the guide slope 1422.

[0150] By installing a guide slope 1422 on the movable member 142 for the locking member 141 to contact, the locking member 141 protrudes from the outer circumferential surface of the mounting portion 123 due to the guide of the guide slope 1422 when the movable member 142 moves along the first direction X. This makes it easier for the movable member 142 to cause the locking member 141 to protrude from the outer circumferential surface of the mounting portion 123, or to allow the locking member 141 to return to the mounting portion 123. By employing a locking mechanism 10 with such a structure, the phenomenon of the movable member 142 and the locking member 141 becoming immobile from each other can be reduced.

[0151] According to some embodiments of this application, referring to Figures 6 and 8, the fastening assembly 14 includes a plurality of locking members 141 that are spaced apart along the circumferential direction of the mounting portion 123.

[0152] For example, the clamping assembly 14 is provided with four locking members 141 spaced apart and evenly arranged around the movable member 142. Of course, in other embodiments, the number of locking members 141 may be two, three, five, or six, etc.

[0153] The fastening assembly 14 is equipped with a plurality of locking members 141 that are spaced apart along the circumferential direction of the mounting portion 123. That is, when all of the locking members 141 protrude from the outer circumferential surface of the mounting portion 123, the locking members 141 are positioned around the mounting portion 123. This structure further improves the structural stability and robustness of the mutual contact between the fastening assembly 14 and the adjustment member 13, and is advantageous in improving the effect of the fastening assembly 14 in sharing the force applied to the screw structure between the locking member 12 and the adjustment member 13.

[0154] In some embodiments, referring to Figures 6 and 8, the locking member 141 is spherical. Of course, in other embodiments, the locking member 141 may have a cubic structure, a rectangular parallelepiped structure, or a conical structure, etc.

[0155] By installing the locking member 141 in a spherical shape, it is made easier to push the locking member 141 so that it protrudes from the outer circumferential surface of the mounting portion 123 when the movable member 142 moves along the first direction X relative to the mounting portion 123, or to allow the locking member 141 to return to inside the mounting portion 123, thereby reducing the phenomenon of the movable member 142 and the locking member 141 becoming immobile from each other.

[0156] Referring to some embodiments of this application, specifically Figures 5, 6, 7, and 8, the locking member 12 includes a connecting portion 121 and a locking portion 122. The connecting portion 121 extends along a first direction X and is inserted into the sleeve 11, and the connecting portion 121 screws into an adjustment member 13. The locking portion 122 is located outside the sleeve 11 and is connected to the end of the connecting portion 121 away from the sleeve 11, and the locking portion 122 protrudes from the outer circumferential surface of the connecting portion 121 along its extending direction, and the locking portion 122 is used to lock with the lock base 300, with the extending direction of the locking portion 122 being perpendicular to the first direction X. The locking member 12 can be switched between a locked state and an unlocked state by rotating the connecting portion 121 by rotating the adjustment member 13 relative to the sleeve 11, thereby locking or releasing the locking portion 122 with the lock base 300.

[0157] Here, the mounting portion 123 is connected to the end of the connecting portion 121 that moves away from the locking portion 122 in the first direction X, and the connecting portion 121 of the locking member 12 is a cylindrical structure extending along the first direction X, and the portion of the connecting portion 121 is inserted into the sleeve 11 along the first direction X. The portion of the connecting portion 121 inserted into the sleeve 11 is screwed into the adjustment member 13, and exemplary, the portion of the adjustment member 13 is fitted to the outside of the connecting portion 121, and the adjustment member 13 has an internal thread, and correspondingly the portion of the connecting portion 121 housed in the adjustment member 13 has an external thread, so that by screwing the connecting portion 121 and the adjustment member 13 together, the adjustment member 13 can rotate the connecting portion 121 around an axis extending along the first direction X. Of course, in other embodiments, the connecting portion 121 may be fitted onto the outside of the adjustment member 13, and the connecting portion 121 may have an internal thread, and correspondingly the portion of the adjustment member 13 that is housed within the connecting portion 121 may have an external thread, so that the connecting portion 121 screws into the adjustment member 13.

[0158] The locking portion 122 is located outside the sleeve 11 and is connected to the end of the connecting portion 121 that is away from the sleeve 11, that is, the connecting portion 121 has a portion that is not inserted into the sleeve 11, and the locking portion 122 is connected to one end of the portion of the connecting portion 121 that is not inserted into the sleeve 11, thereby positioning the locking portion 122 at a distance from the sleeve 11 along the first direction X.

[0159] The locking portion 122 protrudes from the outer circumferential surface of the connecting portion 121 along its extending direction; that is, in the direction of the locking portion 122's extension, the locking portion 122 extends from the outer circumferential surface of the connecting portion 121. For example, in Figures 6 and 7, the extending direction of the locking portion 122 is perpendicular to the first direction X, thereby forming a "T" shape structure between the locking portion 122 and the connecting portion 121. Of course, in other embodiments, the locking portion 122 and the connecting portion 121 may form an "L" shape structure.

[0160] The adjustment member 13 rotates relative to the sleeve 11, thereby rotating the connecting portion 121 to engage or disengage the locking portion 122 with the lock base 300, thereby allowing the locking member 12 to be switched between a locked state and an unlocked state. In other words, when the adjustment member 13 rotates relative to the sleeve 11, the connecting portion 121 can rotate the locking portion 122 about an axis extending along the first direction X, thereby changing the direction of extension of the locking portion 122, thereby allowing the locking portion 122 to wrap over or disengage from the lock base 300, thereby engaging or disengaging the locking portion 122 with the lock base 300.

[0161] Referring to Figure 7 in some embodiments, and further to Figure 11, Figure 11 is a schematic diagram of the connection between the locking mechanism 10 and the locking base 300 according to some embodiments of the present application. The locking base 300 is provided with a locking hole 310 into which a locking member 12 is inserted, the locking hole 310 penetrates both sides of the locking base 300 along a first direction X, and after the locking member 12 is inserted into the locking hole 310, the locking portion 122 of the locking member 12 can be rotated around an axis extending along the first direction X by rotating the adjustment member 13, thereby bonding the locking portion 122 to the surface of the locking base 300 away from the sleeve 11, thereby connecting the locking mechanism 10 and the locking base 300 in the first direction X By bonding them together, mutual locking between the locking mechanism 10 and the locking base 300 can be achieved. Conversely, by rotating the adjustment member 13, the locking portion 122 of the locking member 12 is rotated so that the projection of the locking portion 122 in the first direction X is located inside the locking hole 310. In this case, the locking member 12 retracts from inside the locking hole 310, allowing the locking mechanism 10 and the locking base 300 to separate in the first direction X, thereby enabling mutual unlocking between the locking mechanism 10 and the locking base 300.

[0162] Here, if the cross-section of the lock hole 310 is rectangular and the extending direction of the locking portion 122 coincides with the longitudinal direction of the cross-section of the lock hole 310, the locking portion 122 can be inserted into or withdrawn from the lock hole 310, and after the locking portion 122 has passed through the lock hole 310 and the extending direction of the locking portion 122 intersects with the longitudinal direction of the cross-section of the lock hole 310, the locking portion 122 can be bonded to the surface of the lock base 300 that is away from the sleeve 11.

[0163] Selectively, a locking groove 320 is provided on the surface of the lock base 300 to which the locking portion 122 is bonded, and the extending direction of the locking groove 320 is perpendicular to the longitudinal direction of the cross-section of the lock hole 310. When the locking portion 122 rotates such that its extending direction and the longitudinal direction of the cross-section of the lock hole 310 are perpendicular to each other, the locking portion 122 can be bonded to the lock base 300, and the locking groove 320 can engage with the locking portion 122. This is advantageous in improving the stability of the mutual lock between the lock mechanism 10 and the lock base 300 by mitigating the phenomenon of play occurring between the lock mechanism 10 and the lock base 300.

[0164] In some embodiments, referring to Figure 7, a locking surface 111 is further formed on the end of the sleeve 11 near the locking portion 122 along a first direction X, and the locking surface 111 is positioned to abut against the side of the lock base 300 facing the sleeve 11 when the locking member 12 is in the locked state. Here, when the locking mechanism 10 and the lock base 300 are bonded along the first direction X, the locking portion 122 and the locking surface 111 abut against the lock base 300 on both sides in the first direction X, respectively. By positioning the locking surface 111 of the sleeve 11 in contact with the side of the lock base 300 facing the sleeve 11 when the locking member 12 is locked to the lock base 300, the locking mechanism 10 can perform a clamping action against the lock base 300 in a first direction X by the locking portion 122 of the locking member 12 and the locking surface 111 of the sleeve 11. This is advantageous in reducing the phenomenon of looseness occurring during use of the locking mechanism 10 and improves the stability of the mutual lock between the locking mechanism 10 and the lock base 300.

[0165] The locking member 12 is provided with a connecting portion 121 and a locking portion 122 connected to one end of the connecting portion 121. The locking portion 122 protrudes from the outer circumferential surface of the connecting portion 121 in its extending direction. By inserting the connecting portion 121 into the sleeve 11 along the first direction X and screwing it with the adjustment member 13, the connecting portion 121 can be rotated when the adjustment member 13 rotates, thereby allowing the locking portion 122 to rotate together with the connecting portion 121. This changes the extending direction of the locking portion 122 in a plane perpendicular to the first direction X, thereby allowing the locking portion 122 to be locked or unlocked to the lock base 300 after rotation. Furthermore, the locking mechanism 10 can be bonded to or detached from the lock base 300 in the first direction X.

[0166] According to some embodiments of this application, referring to Figures 6 and 7, a third stopper portion 112 is provided on the sleeve 11, and a fourth stopper portion 1211 is provided on the connecting portion 121. The third stopper portion 112 and the fourth stopper portion 1211 are fitted together to limit the rotation angle of the connecting portion 121.

[0167] Here, the third stopper portion 112 and the fourth stopper portion 1211 fit together to limit the rotation angle of the connecting portion 121 relative to the sleeve 11. The structures of the third stopper portion 112 and the fourth stopper portion 1211 can vary. For example, the third stopper portion 112 may be a stopper groove installed on the inner circumferential surface of the sleeve 11, and correspondingly, the fourth stopper portion 1211 may be a projection protruding from the outer circumferential surface of the connecting portion 121. The projection is inserted into the stopper groove and fits together to limit the rotation angle of the connecting portion 121. Of course, the third stopper portion 112 and the fourth stopper portion 1211 may both be protrusions. The third stopper portion 112 is provided as a protrusion on one end of the sleeve 11 in the first direction X, and the fourth stopper portion 1211 is provided as a protrusion on the outer circumferential surface of the connecting portion 121. The fourth stopper portion 1211 comes into contact with the third stopper portion 112 when the connecting portion 121 rotates relative to the sleeve 11, and the rotation angle of the connecting portion 121 can be limited by the mutual fitting of the third stopper portion 112 and the fourth stopper portion 1211.

[0168] Selectively, the number of third stopper portions 112 and fourth stopper portions 1211 may be one or more. Exemplarily, in the embodiments of this application, there are two third stopper portions 112, and correspondingly, there are also two fourth stopper portions 1211, with the two fourth stopper portions 1211 provided on both sides of the connecting portion 121 along the radial direction of the connecting portion 121.

[0169] By installing a third stopper portion 112 and a fourth stopper portion 1211 corresponding to the sleeve 11 and the connection portion 121, the third stopper portion 112 and the fourth stopper portion 1211 fit together to limit the rotation angle of the connection portion 121. This allows the connection portion 121 to lock or unlock the locking portion 122 to the lock base 300 by the fitting restriction of the third stopper portion 112 and the fourth stopper portion 1211. This makes it easy to switch the locking member 12 between a locked state and an unlocked state. The structure is simple, operation is easy, and the phenomenon in which the locking portion 122 cannot lock to the lock base 300 because the angle of rotation of the locking portion 122 together with the connection portion 121 is too large is mitigated, which is advantageous in improving the reliability of mutual locking between the locking mechanism 10 and the lock base 300.

[0170] According to some embodiments of this application, referring to Figures 7 and 9, the third stopper portion 112 and the fourth stopper portion 1211 are further configured to move the locking member 12 between a first position and a second position along the first direction X by cooperating to guide the connecting portion 121 to move along the first direction X as the adjustment member 13 rotates relative to the sleeve 11. When the locking member 12 is in the first position, the locking member 12 is in a locked state, which allows the locking portion 122 to engage with the lock base 300. When the locking member 12 is in the second position, the locking member 12 is in an unlocked state, which allows the locking portion 122 to release from the lock base 300.

[0171] Here, the third stopper portion 112 and the fourth stopper portion 1211 are further configured to cooperate in guiding the connecting portion 121 to move along the first direction X as the adjusting member 13 rotates relative to the sleeve 11. That is, as the adjusting member 13 rotates the connecting portion 121 relative to the sleeve 11, the third stopper portion 112 and the fourth stopper portion 1211 engage to limit the rotation angle of the connecting portion 121 and at the same time guide the connecting portion 121 to move in the first direction X relative to the sleeve 11, thereby giving the locking member 12 two endpoint positions, namely the first position and the second position, relative to the sleeve 11 in the first direction X. In other words, as the adjustment member 13 rotates the connecting portion 121 relative to the sleeve 11, the connecting portion 121 can also move further along the first direction X relative to the sleeve 11, thereby rotating the connecting portion 121 so that the locking portion 122 adheres to the side of the lock base 300 away from the sleeve 11, the locking member 12 is in a first position, and correspondingly, as the locking member 12 moves to a second position, the projection of the locking portion 122 in the first direction X is located within the lock hole 310 of the lock base 300, so that the locking member 12 can detach from the lock base 300 along the first direction X.

[0172] The adjustment member 13 can rotate the connecting portion 121 when it rotates relative to the sleeve 11, and can move the connecting portion 121 along the first direction X. For example, in Figure 7, the adjustment member 13 and the connecting portion 121 are screwed together, thereby allowing the adjustment member 13 to rotate the connecting portion 121, and if rotation in the circumferential direction of the connecting portion 121 is restricted, the adjustment member 13 can provide a transport force to the connecting portion 121 along the first direction X, thereby enabling the connecting portion 121 to move along the first direction X.

[0173] The third stopper portion 112 and the fourth stopper portion 1211 limit the rotation angle of the connecting portion 121 and cooperate to guide the connecting portion 121 to move in the first direction X relative to the sleeve 11, enabling the adjustment member 13 to rotate the connecting portion 121 relative to the sleeve 11, and simultaneously moving the locking member 12 between the first and second positions along the first direction X, thereby enabling the adjustment member 13 to lock the locking portion 122 with the lock base 300 and simultaneously bring the locking portion 122 and the lock base 300 into contact with each other, thereby reducing the size of the gap between the locking portion 122 and the lock base 300, and further reducing the vibration phenomenon between the lock mechanism 10 and the lock base 300.

[0174] According to some embodiments of this application, referring to Figures 6 and 7, the third stopper portion 112 is a stopper groove installed on the inner circumferential surface of the sleeve 11, and the fourth stopper portion 1211 is a projection that protrudes on the outer circumferential surface of the connecting portion 121, with at least a portion of the projection housed within the stopper groove.

[0175] Here, the third stopper portion 112 is a stopper groove, and the fourth stopper portion 1211 is a projection. By inserting the projection into the stopper groove, the trajectory of the projection's movement is restricted and guided by the stopper groove, thereby enabling the connection portion 121 to be restricted from moving between the first position and the second position along the rotation angle and the first direction X by the fitting action of the third stopper portion 112 and the fourth stopper portion 1211.

[0176] It should be explained that in other embodiments, the third stopper portion 112 and the fourth stopper portion 1211 may have other structures. For example, the third stopper portion 112 is a projection that protrudes on the inner circumferential surface of the sleeve 11, and correspondingly, the fourth stopper portion 1211 is a stopper groove installed on the outer circumferential surface of the connecting portion 121.

[0177] The third stopper portion 112 and the fourth stopper portion 1211 are a stopper groove installed on the inner circumferential surface of the sleeve 11 and a projection installed on the outer circumferential surface of the connecting portion 121, respectively. By inserting the projection into the stopper groove, the rotation angle of the connecting portion 121 is limited by the constraint of the stopper groove. At the same time, the projection allows the connecting portion 121 to rotate relative to the sleeve 11 by the guide of the stopper groove, and can move along the first direction X relative to the sleeve 11. The structure is simple, easy to implement, and relatively stable.

[0178] In some embodiments, referring to Figure 7 and further to Figure 12, Figure 12 is a cross-sectional view of the sleeve 11 of the locking mechanism 10 according to some embodiments of the present application. The stopper groove includes a first groove segment 1121, a second groove segment 1122, and a third groove segment 1123 that are sequentially connected, the first groove segment 1121 and the third groove segment 1123 both extending along a first direction X, the first groove segment 1121 and the third groove segment 1123 being spaced apart along the circumferential direction of the connection 121, and the third groove segment 1123 being closer to the locking 122 than the first groove segment 1121 along the first direction X. When the locking member 12 is in the first position, the projection is located within the first groove segment 1121, and when the locking member 12 is in the second position, the projection is located within the third groove segment 1123.

[0179] Here, the first groove segment 1121 and the third groove segment 1123 are spaced apart along the circumferential direction of the connecting portion 121, and the first groove segment 1121 and the third groove segment 1123 are spaced apart along the first direction X, that is, there is a distance between the first groove segment 1121 and the third groove segment 1123 of the stopper groove in the first direction X. There is also a distance between them in the circumferential direction of the connecting portion 121. It should be explained that the first groove segment 1121 and the third groove segment 1123 are spaced apart in the first direction X and in the circumferential direction of the connecting portion 121. Therefore, the second groove segment 1122, which is connected to the first groove segment 1121 and the third groove segment 1123, has a helical structure surrounding the connecting portion 121. As a result, when the projection is located within the first groove segment 1121 and the third groove segment 1123, the connecting portion 121 can be moved by the adjustment member 13 only along the first direction X. However, when the projection is located within the second groove segment 1122, the connecting portion 121 can be moved by the adjustment member 13 along the first direction X and can also be rotated around an axis extending along the first direction X.

[0180] When the locking member 12 is in the first position, the projection is located within the first groove segment 1121, and when the locking member 12 is in the second position, the projection is located within the third groove segment 1123. In other words, after the projection of the connecting portion 121 moves from the first groove segment 1121 to the third groove segment 1123, the locking member 12 can move from the first position to the second position.

[0181] Of course, the structure of the stopper groove is not limited to this, and in some embodiments, the stopper groove may have other structures. For example, the stopper groove extends along the first direction X and has a relatively wide width in the circumferential direction of the connecting portion 121, thereby having two groove side walls facing each other in the circumferential direction of the connecting portion 121, the two groove side walls are spaced apart in the circumferential direction of the connecting portion 121, and both groove side walls are used for a projection to abut against, the projection is inserted into the stopper groove and protrudes. The projection moves between the two groove side walls along the circumferential direction of the connecting portion 121, thereby limiting the rotation angle of the connecting portion 121. When the projection contacts the groove side wall of the stopper groove, the groove side wall of the stopper groove prevents the rotation of the connecting portion 121, thereby limiting the rotation angle of the connecting portion 121. Furthermore, after being blocked by the groove side wall of the stopper groove, the projection of the connecting portion 121 moves along the first direction X guided by the groove side wall of the stopper groove, thereby enabling the connecting portion 121 to move along the first direction X.

[0182] The first groove segment 1121 and the third groove segment 1123 of the stopper groove are both installed in a structure that extends along the first direction X, and the first groove segment 1121 and the third groove segment 1123 are spaced apart in both the first direction X and the circumferential direction of the connecting portion 121, so that the second groove segment 1122 is a helical groove connected between the first groove segment 1121 and the third groove segment 1123, so that the projection of the connecting portion 121 is located within the first groove segment 1121 and the third groove segment 1123. In this case, the locking member 12 can only move along the first direction X in conjunction with the extending direction of the first groove segment 1121 and the second groove segment 1122. However, when the projection of the connecting portion 121 is located within the second groove segment 1122, it can rotate relative to the sleeve 11 along with the extending direction of the second groove segment 1122 and move relative to the sleeve 11 along the first direction X, thereby limiting the rotation angle of the locking member 12 and allowing it to move between the first and second positions along the first direction X. Furthermore, by positioning the third groove segment 1123 closer to the locking portion 122 in the first direction X than the first groove segment 1121, the locking portion 122 can be locked to the lock base 300 when the projection is located within the first groove segment 1121, and at the same time, it can be brought closer to the sleeve 11, enabling the locking portion 122 to abut against the lock base 300 in the first direction X.

[0183] According to some embodiments of this application, referring to Figures 6 and 7, the adjustment member 13 includes a connecting segment 134 installed within the sleeve 11, the connecting segment 134 is fitted onto the outside of the connecting portion 121, and the connecting segment 134 is screwed into the connecting portion 121.

[0184] Here, the connecting segment 134 is fitted onto the outside of the connecting portion 121, and the connecting segment 134 is screwed into the connecting portion 121 to achieve screwing of the locking member 12 and the adjustment member 13. That is, the connecting segment 134 of the adjustment member 13 is screwed onto the outside of the connecting portion 121, meaning that the adjustment member 13 is fitted onto the outside of the connecting portion 121, and an internal thread is installed on the inner circumferential surface of the adjustment member 13, and correspondingly an external thread is installed on the outer circumferential surface of the connecting portion 121, thereby screwing the connecting portion 121 and the connecting segment 134 together. Of course, in other embodiments, the locking mechanism 10 may have a structure in which the connecting portion 121 is screwed onto the outside of the connecting segment 134 of the adjustment member 13.

[0185] The adjustment member 13 has a connecting segment 134, and the connecting segment 134 is screwed onto the outside of the connecting portion 121, thereby achieving screw engagement between the locking member 12 and the adjustment member 13. By rotating the adjustment member 13, the connecting portion 121 can be rotated together with it. Furthermore, when the connecting portion 121 is restricted from rotating in the circumferential direction, the adjustment member 13 can provide the connecting portion 121 with a transport force along the first direction X, thereby enabling the connecting portion 121 to move in the first direction X. The structure is simple and easy to implement.

[0186] According to some embodiments of this application, with reference to Figures 6, 7, and 8, the locking mechanism 10 may further include an anti-loosening assembly 15 installed between the sleeve 11 and the adjustment member 13, the anti-loosening assembly 15 being used to selectively lock the adjustment member 13 and the sleeve 11 to restrict the adjustment member 13 from rotating relative to the sleeve 11.

[0187] Here, the anti-loosening assembly 15 is used to selectively lock the adjustment member 13 and the sleeve 11 to restrict the adjustment member 13 from rotating relative to the sleeve 11. That is, the anti-loosening assembly 15 can selectively lock or unlock the adjustment member 13 and the sleeve 11. When the anti-loosening assembly 15 locks the adjustment member 13 and the sleeve 11, the adjustment member 13 cannot rotate relative to the sleeve 11, and when the anti-loosening assembly 15 unlocks the adjustment member 13 and the sleeve 11, the adjustment member 13 can rotate relative to the sleeve 11.

[0188] The locking mechanism 10 is further equipped with an anti-loosening assembly 15. By installing the anti-loosening assembly 15 between the sleeve 11 and the adjustment member 13, the adjustment member 13 and the sleeve 11 can be selectively locked. That is, when the anti-loosening assembly 15 releases the sleeve 11 and the adjustment member 13, the anti-loosening assembly 15 allows the adjustment member 13 to rotate relative to the sleeve 11, and activates the locking member 12 relative to the sleeve 11, thereby engaging or disengaging the locking member 12 with the locking base 300. When the anti-loosening assembly 15 locks the sleeve 11 and the adjustment member 13, the anti-loosening assembly 15 can restrict the rotation of the adjustment member 13 relative to the sleeve 11, thereby mitigating the phenomenon of poor engagement between the locking member 12 and the locking base 300 due to the mis-rotation of the adjustment member 13, improving the locking effect between the locking member 12 and the locking base 300, which is advantageous for improving the stability and reliability of the mutual locking between the locking mechanism 10 and the locking base 300.

[0189] According to some embodiments of this application, with reference to Figures 6, 7, and 8, the anti-loosening assembly 15 may include a first clutch member 151 and a second clutch member 152. The first clutch member 151 is mounted on the sleeve 11, and the second clutch member 152 is mounted on the adjustment member 13. The first clutch member 151 and the second clutch member 152 are configured to restrict the adjustment member 13 from rotating relative to the sleeve 11 when they are locked and fitted together, and to allow the adjustment member 13 to rotate relative to the sleeve 11 when they are disengaged from each other.

[0190] Here, the first clutch member 151 and the second clutch member 152 play a role in restricting the adjustment member 13 from rotating relative to the sleeve 11 when they are locked and fitted together, and conversely, when the first clutch member 151 and the second clutch member 152 are disengaged from each other, they allow the adjustment member 13 to rotate relative to the sleeve 11. Selectively, the structures of the first clutch member 151 and the second clutch member 152 may vary. For example, the first clutch member 151 may be fixed inside the sleeve 11, and the second clutch member 152 may be externally fitted to the outside of the adjustment member 13 so as to be movable along the first direction X, locking circumferentially with the adjustment member 13. That is, the second clutch member 152 can move along the first direction X relative to the adjustment member 13, but cannot rotate circumferentially relative to the adjustment member 13. This allows the first clutch member 151 and the second clutch member 152 to engage and restrict the adjustment member 13 from rotating relative to the sleeve 11 when the first clutch member 151 and the second clutch member 152 disengage from each other. Of course, the first clutch member 151 may be movably installed within the sleeve 11 along the first direction X and be structured to lock with the sleeve 11 in the circumferential direction, and correspondingly, the second clutch member 152 is fixed and fitted to the outside of the adjustment member 13.

[0191] Of course, the structure of the anti-loosening assembly 15 is not limited to this, and in other embodiments, the anti-loosening assembly 15 may have other structures. For example, the anti-loosening assembly 15 may be a bolt screwed onto the sleeve 11. When the bolt is tightened, the bolt can contact the adjustment member 13, restricting the adjustment member 13 from rotating relative to the sleeve 11. When the bolt is loosened, the bolt can separate from the adjustment member 13, allowing the adjustment member 13 to rotate relative to the sleeve 11. Thus, the anti-loosening assembly 15 can selectively lock the adjustment member 13 and the sleeve 11.

[0192] The anti-loosening assembly 15 is equipped with a first clutch member 151 and a second clutch member 152 that can lock and engage with each other and disengage from each other. The first clutch member 151 and the second clutch member 152 are installed on the sleeve 11 and the adjustment member 13, respectively. The locking engagement of the first clutch member 151 and the second clutch member 152 restricts the adjustment member 13 from rotating relative to the sleeve 11, and when the first clutch member 151 and the second clutch member 152 disengage from each other, the adjustment member 13 can rotate relative to the sleeve 11. This enables the anti-loosening assembly 15 to selectively lock the adjustment member 13 and the sleeve 11.

[0193] In some embodiments, continuing to refer to Figures 6, 7, and 8, the first clutch member 151 and the second clutch member 152 are arranged along a first direction X, the first clutch member 151 is fixed to the sleeve 11, the second clutch member 152 and the adjustment member 13 are locked in the circumferential direction, and the second clutch member 152 is movably mounted on the adjustment member 13 along the first direction X, thereby allowing the second clutch member 152 to engage with or disengage from the first clutch member 151.

[0194] Here, the first clutch member 151 is fixed to the inside of the sleeve 11, and the fixed connection structure between the first clutch member 151 and the sleeve 11 can vary. For example, the first clutch member 151 can be fixedly connected to the sleeve 11 by a structure such as welding, bonding, or locking.

[0195] The second clutch member 152 and the adjustment member 13 are locked in the circumferential direction, and the second clutch member 152 is installed to be movable on the adjustment member 13 along the first direction X, that is, the second clutch member 152 can move along the first direction X relative to the adjustment member 13 but cannot rotate circumferentially relative to the adjustment member 13, thereby allowing the second clutch member 152 to move along the first direction X and engage with or disengage from the first clutch member 151.

[0196] For example, the second clutch member 152 is fitted onto the outside of the adjustment member 13.

[0197] The first clutch member 151 and the second clutch member 152 are arranged along a first direction X, and the second clutch member 152 is movably mounted on the adjustment member 13 along the first direction X. By fixing the first clutch member 151 to the sleeve 11 and mounting the second clutch member 152 in a structure that locks circumferentially with the adjustment member 13, moving the second clutch member 152 enables locking or disengaging between the second clutch member 152 and the first clutch member 151, thereby restricting the adjustment member 13 from rotating relative to the sleeve 11, or allowing the adjustment member 13 to rotate relative to the sleeve 11. Such a locking assembly 15 is simple in structure and easy to operate and implement.

[0198] Referring to several embodiments of this application, with reference to Figures 6, 7 and 8, and further to Figure 13, Figure 13 is a schematic diagram of the structure of a second clutch member 152 of a locking assembly 15 of a locking mechanism 10 according to several embodiments of this application. The adjustment member 13 includes a guide segment 135 installed within a sleeve 11, and the second clutch member 152 is externally fitted to the outside of the guide segment 135 so as to be movable along a first direction X, with a first circumferential stopper portion 1351 provided on the outer circumferential surface of the guide segment 135, and a second circumferential stopper portion 1521 provided on the inner circumferential surface of the second clutch member 152, the second circumferential stopper portion 1521 and the first circumferential stopper portion 1351 engaging to achieve circumferential locking of the second clutch member 152 and the adjustment member 13.

[0199] Here, the guide segment 135 is connected to one end of the connecting segment 134, and the guide segment 135 is further away from the locking portion 122 than the connecting segment 134 in the first direction X, the first clutch member 151 is fixed within the sleeve 11 and positioned to surround the adjustment member 13, and the second clutch member 152 is movably fitted outside the guide segment 135 of the adjustment member 13 along the first direction X, so that the second clutch member 152 can move relative to the adjustment member 13 along the first direction X, thereby allowing the second clutch member 152 to lock or disengage from the first clutch member 151.

[0200] A first circumferential stopper portion 1351 is provided on the outer circumferential surface of the guide segment 135, and a second circumferential stopper portion 1521 is provided on the inner circumferential surface of the second clutch member 152. The first circumferential stopper portion 1351 and the second circumferential stopper portion 1521 fit together and serve to restrict the rotation of the second clutch member 152 circumferentially relative to the adjustment member 13. When the second clutch member 152 and the first clutch member 151 are locked together, the first clutch member 151 restricts the rotation of the second clutch member 152 relative to the sleeve 11, thereby further restricting the rotation of the adjustment member 13 relative to the sleeve 11.

[0201] Selectively, the structures of the first circumferential stopper portion 1351 and the second circumferential stopper portion 1521 may vary. For example, the first circumferential stopper portion 1351 may be a protruding block that protrudes from the outer circumferential surface of the guide segment 135 of the adjustment member 13, and the protruding block has a structure that extends along the first direction X. Correspondingly, the second circumferential stopper portion 1521 may be a guide groove installed on the inner circumferential surface of the second clutch member 152, and the guide groove extends along the first direction X. The protruding block catches in the guide groove, enabling the second clutch member 152 to move along the first direction X relative to the guide segment 135 of the adjustment member 13 and lock circumferentially with the guide segment 135 of the adjustment member 13. Of course, the first circumferential stopper portion 1351 may be a guide groove installed on the outer circumferential surface of the guide segment 135 of the adjustment member 13, and correspondingly, the second circumferential stopper portion 1521 is a convex block installed on the inner circumferential surface of the second clutch member 152.

[0202] It should be explained that in an embodiment in which a mounting channel 133 is installed at one end of the adjustment member 13 and the execution unit 132 is installed within the mounting channel 133, the mounting channel 133 is installed within the guide segment 135, and the end of the guide segment 135 that moves away from the connecting segment 134 in the first direction X, and correspondingly the execution unit 132 is connected within the guide segment 135.

[0203] The adjustment member 13 has a guide segment 135, and the second clutch member 152 is fitted to the outside of the guide segment 135 so as to be movable along the first direction X. A first circumferential stopper portion 1351 is installed on the outer circumferential surface of the guide segment 135, and a second circumferential stopper portion 1521 that engages with the first circumferential stopper portion 1351 is installed on the inner circumferential surface of the second clutch member 152, thereby enabling the second clutch member 152 to move along the first direction X relative to the adjustment member 13 and to be locked in the circumferential direction.

[0204] In some embodiments, the first circumferential stopper portion 1351 is a spline extending along the first direction X, and the second circumferential stopper portion 1521 is a spline groove that engages with the spline.

[0205] By arranging the first circumferential stopper portion 1351 and the second circumferential stopper portion 1521 to form a spline and spline groove extending along the first direction X, that is, a spline extending along the first direction X is installed on the outer circumferential surface of the guide segment 135 of the adjustment member 13, and a spline groove that engages with the spline is installed on the inner circumferential surface of the second clutch member 152, the second clutch member 152 can be locked circumferentially to the adjustment member 13, but can also move along the first direction X relative to the adjustment member 13, resulting in a simple structure and relatively high stability.

[0206] Referring to several embodiments of this application, with reference to Figures 6 and 13, and further to Figure 14, Figure 14 is a schematic diagram of the structure of a first clutch member 151 of a locking assembly 15 of a locking mechanism 10 according to several embodiments of this application. Along a first direction X, a first toothed portion 1511 is provided at the end of the first clutch member 151 toward the second clutch member 152, and a second toothed portion 1522 is provided at the end of the second clutch member 152 toward the first clutch member 151, the second toothed portion 1522 being used to engage with the first toothed portion 1511 to achieve a locking fit between the second clutch member 152 and the first clutch member 151.

[0207] Here, the first tooth profile portion 1511 is a tooth profile structure installed on the end of the first clutch member 151 facing the second clutch member 152, and the multiple teeth of the first tooth profile portion 1511 are arranged along the circumferential direction of the first clutch member 151, with each tooth extending along the radial direction of the first clutch member 151. The second tooth profile portion 1522 is a tooth profile structure installed on the end of the second clutch member 152 facing the first clutch member 151, and the multiple teeth of the second tooth profile portion 1522 are arranged along the circumferential direction of the second clutch member 152, with each tooth extending along the radial direction of the second clutch member 152. As a result, when the second clutch member 152 moves along the first direction X and approaches the first clutch member 151, the second tooth profile 1522 and the first tooth profile 1511 engage with each other, thereby achieving mutual locking between the second clutch member 152 and the first clutch member 151, and restricting the adjustment member 13 from rotating relative to the sleeve 11.

[0208] It should be noted that in other embodiments, the first clutch member 151 and the second clutch member 152 may have other structures. For example, a stopper hole may be provided at the end of the first clutch member 151 facing the second clutch member 152 in the first direction X, and a plug may be provided at the end of the second clutch member 152 facing the first clutch member 151 in the first direction X. When the second clutch member 152 moves along the first direction X and approaches the first clutch member 151, the plug can be inserted into the stopper hole to achieve mutual locking between the second clutch member 152 and the first clutch member 151, thereby restricting the adjustment member 13 from rotating relative to the sleeve 11.

[0209] A first tooth profile 1511 is provided at the end of the first clutch member 151 facing the second clutch member 152, and correspondingly, a second tooth profile 1522 is provided at the end of the second clutch member 152 facing the first clutch member 151. As the second clutch member 152 moves in the first direction X, the second tooth profile 1522 and the first tooth profile 1511 can be engaged or disengaged. This achieves locking or disengaging of the second clutch member 152 and the first clutch member 151. When the first tooth profile 1511 and the second tooth profile 1522 engage with each other, the first clutch member 151 and the second clutch member 152 are fitted together, restricting the rotation of the adjustment member 13 relative to the sleeve 11. This results in a simple structure and easy implementation. Furthermore, by providing the structures of the first tooth profile 1511 and the second tooth profile 1522 on the first clutch member 151 and the second clutch member 152, respectively, the difficulty of locking and disengaging the first clutch member 151 and the second clutch member 152 can be reduced, which is advantageous for mutual locking and disengaging the first clutch member 151 and the second clutch member 152.

[0210] According to some embodiments of this application, referring to Figure 8, along a first direction X, a first bevel 1512 is formed at the end of the first clutch member 151 toward the second clutch member 152, and a second bevel 1523 is formed at the end of the second clutch member 152 toward the first clutch member 151, and the second bevel 1523 and the first bevel 1512 are matched. The first tooth profile 1511 is positioned on the first bevel 1512, and the second tooth profile 1522 is positioned on the second bevel 1523.

[0211] Here, the second inclined surface 1523 and the first inclined surface 1512 are matched, that is, the first inclined surface 1512 installed on the first clutch member 151 has the same shape as the second inclined surface 1523 installed on the second clutch member 152, thereby allowing the first inclined surface 1512 to adhere to the second inclined surface 1523.

[0212] The first tooth profile portion 1511 is positioned on the first inclined surface 1512, and the second tooth profile portion 1522 is positioned on the second inclined surface 1523; that is, the first tooth profile portion 1511 is positioned convexly on the first inclined surface 1512, and the second tooth profile portion 1522 is positioned convexly on the second inclined surface 1523.

[0213] A first inclined surface 1512 is provided at the end of the first clutch member 151 facing the second clutch member 152, and the first tooth profile portion 1511 is positioned on the first inclined surface 1512. Correspondingly, a second inclined surface 1523 that matches the first inclined surface 1512 is provided at the end of the second clutch member 152 facing the first clutch member 151, and the second tooth profile portion 1522 is positioned on the second inclined surface 1523. By adopting such a structure, it is possible to realize an inclined structure in which the first tooth profile portion 1511 and the second tooth profile portion 1522 match each other, thereby providing a certain guiding effect and facilitating mutual engagement between the first tooth profile portion 1511 and the second tooth profile portion 1522.

[0214] In some embodiments, referring to Figures 8, 13, and 14, the first inclined surface 1512 is a concave surface installed on the first clutch member 151, and the second inclined surface 1523 is a convex surface installed on the second clutch member 152.

[0215] Here, the first inclined surface 1512 is a concave surface installed on the first clutch member 151, that is, the first inclined surface 1512 is installed at the end of the first clutch member 151 toward the second clutch member 152 and is an inclined surface that is concave inward, and as a result the first inclined surface 1512 is a conical surface that is concave inside the first clutch member 151.

[0216] The second inclined surface 1523 is a convex surface installed on the second clutch member 152, that is, the second inclined surface 1523 is installed on the end of the second clutch member 152 toward the first clutch member 151 and is an inclined surface that protrudes outward, thereby the second inclined surface 1523 is a conical surface that protrudes to the outside of the second clutch member 152.

[0217] By setting the first inclined surface 1512 on a concave surface and the second inclined surface 1523 on a convex surface, the second clutch member 152 can be inserted into the first clutch member 151 when the second tooth profile 1522 of the second clutch member 152 engages with the first tooth profile 1511 of the first clutch member 151. This is advantageous in improving the stability and reliability of the mutual locking between the second clutch member 152 and the first clutch member 151, and reduces the phenomenon of slippage when the second clutch member 152 and the first clutch member 151 lock and fit together.

[0218] According to some embodiments of the present application, with reference to Figures 6, 7, and 8, the anti-loosening assembly 15 may further include a second elastic member 153 positioned between the sleeve 11 and the second clutch member 152, the second elastic member 153 being configured to lock the second clutch member 152 and the first clutch member 151 by driving the second clutch member 152 to move in a direction toward the first clutch member 151 along a first direction X.

[0219] Here, a second elastic member 153 is installed between the sleeve 11 and the second clutch member 152, thereby providing an elastic force to the second clutch member 152, which causes the second clutch member 152 to tend to move in the first direction X toward the first clutch member 151. Thus, in actual use, simply pushing the second clutch member 152 away by overcoming the elastic force of the second elastic member 153 drives the adjustment member 13 to rotate relative to the sleeve 11, enabling the locking member 12 to switch between locked and unlocked states. After the state switching of the locking member 12 is complete, releasing the force pushing the second clutch member 152 causes the second clutch member 152 to move toward and lock with the first clutch member 151 due to the elastic force of the second elastic member 153, thereby achieving a rotation limiting function between the adjustment member 13 and the sleeve 11.

[0220] Selectively, the structure of the second elastic member 153 may vary. For example, the second elastic member 153 may be a spring, an elastic sheet, or elastic rubber installed between the sleeve 11 and the second clutch member 152. Exemplarily, in Figures 6 and 8, the second elastic member 153 is a spring, which is fitted onto the outside of the guide segment 135 of the adjustment member 13, and both ends of the spring abut against the inner circumferential wall of the sleeve 11 and the side of the second clutch member 152 away from the first clutch member 151, respectively.

[0221] It should be explained that the structure in which the second elastic member 153 is installed between the sleeve 11 and the second clutch member 152 can vary. For example, the second elastic member 153 may be directly connected at both ends to the sleeve 11 and the second clutch member 152, or it may be indirectly connected to the sleeve 11 and the second clutch member 152. In other words, the second elastic member 153 is connected to the sleeve 11 and the second clutch member 152 via other members.

[0222] In some embodiments, referring to Figures 6, 7, and 8, the anti-loosening assembly 15 may further include a stopper 154. The stopper 154 is connected within the sleeve 11 and surrounds the outside of the guide segment 135 of the adjustment member 13, and the elastic member is fitted onto the outside of the guide segment 135 of the adjustment member 13, with both ends of the elastic member in a first direction X contacting the stopper 154 and the second clutch member 152, respectively. Employing an anti-loosening assembly 15 with such a structure is advantageous in reducing the difficulty of assembly in which the elastic member is assembled between the sleeve 11 and the second clutch member 152, improving the assembly stability in which the elastic member is assembled between the sleeve 11 and the second clutch member 152, and mitigating the phenomenon of the elastic member falling off.

[0223] Here, the stopper 154 is connected inside the sleeve 11 and surrounded on the outside of the adjustment member 13; that is, the stopper 154 is fitted onto the outside of the adjustment member 13, and the stopper 154 is connected to the inner circumferential wall of the sleeve 11. Exemplarily, the connection structure between the stopper 154 and the sleeve 11 may vary, for example, by welding, bonding, or locking.

[0224] Both ends of the elastic member in the first direction X abut against the stopper 154 and the second clutch member 152, respectively; that is, one end of the elastic member abuts against the second clutch member 152, and the other end abuts indirectly against the sleeve 11 via the stopper 154.

[0225] The anti-loosening assembly 15 is further equipped with a second elastic member 153, which is installed between the sleeve 11 and the second clutch member 152. The second elastic member 153 applies a force to the second clutch member 152 in a first direction X, similar to the force applied to the first clutch member 151, thereby locking the first clutch member 151 and the second clutch member 152 together. By adopting an anti-loosening assembly 15 with such a structure, the stability of the mutual locking between the first clutch member 151 and the second clutch member 152 can be further improved, reducing the phenomenon of accidental disengagement between the first clutch member 151 and the second clutch member 152. Furthermore, after the second clutch member 152 and the first clutch member 151 have disengaged from each other, the second elastic member 153 can automatically lock the second clutch member 152 and the first clutch member 151 together, eliminating the need for artificial intervention and making operation and use easier.

[0226] According to some embodiments of this application, the application further provides a battery assembly 100 comprising a battery 20 and a locking mechanism 10 of any one of the above solutions, wherein the locking mechanism 10 is mounted on the battery 20.

[0227] Referring to Figures 3 and 4, the battery 20 may include a housing 21 and a battery cell 22, the battery cell 22 being used to house within the housing 21, and the locking mechanism 10 being mounted on the housing 21.

[0228] The structure by which the locking mechanism 10 is selectively mounted on the battery 20 may vary. For example, the locking mechanism 10 may be connected to the battery 20 by a structure such as bolting, bonding, welding, or locking.

[0229] By mounting the locking mechanism 10 on the battery 20, the battery 20 can be locked or unlocked with the locking base 300 of the target member via the locking mechanism 10, thereby realizing the power exchange function of the battery 20.

[0230] According to some embodiments of the present application, the present application further provides a power-consuming device, referring to Figures 2, 3 and 11, the power-consuming device comprises a locking base 300 and a battery assembly 100 of any one of the above-described solutions, wherein the locking mechanism 10 is used to bond or detach the locking base 300 along a first direction X, and the battery 20 of the battery assembly 100 is used to provide electrical energy to the power-consuming device.

[0231] The power-consuming device may be a device or system that utilizes any one of the aforementioned batteries 20.

[0232] For the sake of explanation, the following embodiments will be described using the example that the power-consuming device in one embodiment of this application is a vehicle 1000.

[0233] Here, the vehicle 1000 has a mounting frame 200, and the lock base 300 is mounted on the mounting frame 200. Optionally, the lock base 300 and the mounting frame 200 may be an integrated structure or separate structures. When the lock base 300 and the mounting frame 200 are an integrated structure, i.e., the lock base 300 is part of the mounting frame 200, and when the lock base 300 and the mounting frame 200 are separate structures, the lock base 300 may be connected to the mounting frame 200 by a structure such as welding, bolting, or locking. Exemplarily, in Figure 2, the lock base 300 and the mounting frame 200 are separate structures, and the lock base 300 is bolted onto the mounting frame 200.

[0234] The battery assembly 100 includes a locking mechanism 10 and a battery 20, the locking mechanism 10 being mounted on the battery 20, and the locking mechanism 10 being used to lock or unlock with a locking base 300 to enable power exchange of the vehicle 1000.

[0235] In some embodiments, referring to Figure 11, the lock base 300 is provided with a lock hole 310 into which a lock member 12 is inserted, the lock hole 310 penetrates both sides of the lock base 300 along a first direction X, and after the lock member 12 is inserted into the lock hole 310, the locking portion 122 of the lock member 12 can be rotated around an axis extending along the first direction X by rotating the adjustment member 13, thereby bonding the locking portion 122 to the surface of the lock base 300 away from the sleeve 11, thereby connecting the lock mechanism 10 and the lock base By bonding 300 in the first direction X, mutual locking between the locking mechanism 10 and the locking base 300 can be achieved. Conversely, by rotating the adjustment member 13, the locking portion 122 of the locking member 12 is rotated so that the projection of the locking portion 122 in the first direction X is located inside the locking hole 310. In this case, the locking member 12 retracts from inside the locking hole 310, allowing the locking mechanism 10 and the locking base 300 to separate in the first direction X, thereby enabling mutual unlocking between the locking mechanism 10 and the locking base 300.

[0236] Here, if the cross-section of the lock hole 310 is rectangular and the extending direction of the locking portion 122 coincides with the longitudinal direction of the cross-section of the lock hole 310, the locking portion 122 can be inserted into or withdrawn from the lock hole 310, and after the locking portion 122 has passed through the lock hole 310 and the extending direction of the locking portion 122 intersects with the longitudinal direction of the cross-section of the lock hole 310, the locking portion 122 can be bonded to the surface of the lock base 300 that is away from the sleeve 11.

[0237] Selectively, a locking groove 320 is provided on the surface of the lock base 300 to which the locking portion 122 is bonded, and the extending direction of the locking groove 320 is perpendicular to the longitudinal direction of the cross-section of the lock hole 310. When the locking portion 122 rotates such that its extending direction and the longitudinal direction of the cross-section of the lock hole 310 are perpendicular to each other, the locking portion 122 can be bonded to the lock base 300, and the locking groove 320 can engage with the locking portion 122. This is advantageous in improving the stability of the mutual lock between the lock mechanism 10 and the lock base 300 by mitigating the phenomenon of play occurring between the lock mechanism 10 and the lock base 300.

[0238] According to some embodiments of the present application, referring to Figure 11, the present application further provides a locking device comprising a locking base 300 and a locking mechanism 10 of any one of the above-described solutions, the locking mechanism 10 being used to bond to or detach from the locking base 300 along a first direction X.

The connecting portion 121 extends along a first direction X and is inserted into the sleeve 11. The connecting portion 121 screws into the adjustment member 13. The locking portion 122 is located outside the sleeve 11 and is connected to the end of the connecting portion 121 away from the sleeve 11. The locking portion 122 protrudes from the outer circumferential surface of the connecting portion 121 along its extending direction and locks into the lock base 300. The locking portion 122 is used for the purpose of the locking member 12, and its extending direction is perpendicular to the first direction X. The mounting portion 123 is connected to the end of the connecting portion 121 away from the locking portion 122. The adjustment member 13 rotates the connecting portion 121 by rotating it relative to the sleeve 11, thereby engaging or disengaging the locking portion 122 with the lock base 300, and thus the locking member 12 can be switched between a locked state and an unlocked state.A third stopper portion 112 is installed on the sleeve 11, and a fourth stopper portion 1211 is installed on the connecting portion 121. The third stopper portion 112 and the fourth stopper portion 1211 are fitted together to limit the rotation angle of the connecting portion 121. Furthermore, the third stopper portion 112 and the fourth stopper portion 1211 cooperate to guide the connecting portion 121 to move along the first direction X when the adjustment member 13 rotates relative to the sleeve 11, causing the locking member 12 to move between a first position and a second position along the first direction X. When the locking member 12 is in the first position, the locking member 12 is in a locked state, allowing the locking portion 122 to be locked to the lock base 300.

The fastening assembly 14 includes a locking member 141, a movable member 142, and a first elastic member 143. The locking member 141 is movably installed within the mounting hole 1231 and is used to protrude from the outer circumferential surface of the mounting portion 123 and then contact the contact surface 131, or to return to the mounting portion 123 and then release from contact with the contact surface 131. The movable member 142 is movably installed within the housing cavity 1232 along a first direction X and is configured to push the locking member 141 so that it protrudes from the outer circumferential surface of the mounting portion 123 when moved along the first direction X relative to the mounting portion 123, or to allow the locking member 141 to return to the mounting portion 123, thereby causing the locking member 141 to contact or release from contact with the contact surface 131. Here, an execution portion 132 is installed inside the adjustment member 13, and the execution portion 132 and the mounting portion 123 are arranged along a first direction X, and a protrusion 1321 is installed at the end of the execution portion 132 facing the mounting portion 123, and the protrusion 1321 is configured to be inserted into the mounting portion 123 and to abut against the movable member 142, and the execution portion 132 can abut against the movable member 142 when the locking member 12 moves from a second position to a first position and push the movable member 142 to move, thereby pushing the locking member 141 out of the outer circumferential surface of the mounting portion 123, and can separate from the movable member 142 when the locking member 12 moves from a first position to a second position, thereby allowing the movable member 142 to return to the mounting portion 123.The first elastic member 143 is installed between the movable member 142 and the cavity bottom surface of the housing cavity 1232, and the first elastic member 143 is configured to drive the movable member 142 to move in a direction closer to the execution part 132 along the first direction X, thereby allowing the locking member 141 to return to the mounting part 123.
