[0003] The present application relates to the field of battery replacement technology, and more specifically, to a locking mechanism, a battery assembly, an electrical device, and a locking device. Background Art

[0004] With the advancement of science and technology, the battery industry has developed rapidly, and the market share and frequency of use of electric equipment are also increasing. Electric vehicles such as electric vehicles are gradually appearing in various application scenarios. At the same time, in order to improve the convenience of electric equipment, especially electric vehicles, battery swap stations for rapid battery replacement have appeared on the market. However, electric equipment needs to be frequently replaced. During the battery replacement process, the locking mechanism between the battery and the power-consuming equipment needs to be switched between locking and unlocking multiple times to lock and separate the battery and the power-consuming equipment. In addition, the locking mechanism needs to bear the weight of the battery, which makes the locking mechanism prone to wear or damage, resulting in a short service life of the locking mechanism and poor reliability. This in turn leads to inconvenience in battery replacement and safety hazards in use.

[0008] In the above technical solution, the locking mechanism is provided with a locking piece and an adjusting piece, and the locking piece includes a connecting portion and a clamping portion. By threading the first connecting section of the connecting portion with the adjusting piece, the connecting portion can be driven to move relative to the sleeve when the adjusting piece is rotated, so as to further drive the clamping portion to rotate around an axis extending along the first direction, thereby realizing the switching of the locking piece between a locked state and an unlocked state, so that the clamping portion can be engaged or released with the lock seat, thereby realizing the engagement or disengagement of the locking mechanism with the lock seat along the first direction, wherein the diameter of the first connecting section of the connecting portion for threading with the adjusting piece is set to be larger than the diameter of the second connecting section The diameter of the screw thread of the first connecting section can further increase the depth of the thread on the first connecting section while improving the structural strength of the first connecting section of the connecting part. On the one hand, the structural strength of the area where the thread is provided on the connecting part can be improved, and the force-bearing capacity can be enhanced to reduce the risk of the connecting part breaking during use. On the other hand, the structural stability of the mutual threaded connection between the first connecting section and the adjusting member can be improved, which is conducive to alleviating the phenomenon of slipping teeth or damage to the thread structure between the connecting part of the locking member and the adjusting member, so as to reduce the risk of failure of the threaded connection between the locking member and the adjusting member, thereby helping to improve the service life and reliability of the locking mechanism.

[0009] In some embodiments, the first connecting section includes a main body and a first external thread, the main body is connected to one end of the second connecting section, the first external thread is protruded on the outer circumferential surface of the main body, and the outer diameter of the first external thread is the diameter of the first connecting section; wherein, a first internal thread is provided on the inner circumferential surface of the adjusting member, and the first internal thread is used to cooperate with the first external thread.

[0010] In the above technical solution, the first connecting section is provided with a main body and a first external thread, and the first external thread is a structure protruding on the outer circumferential surface of the main body. Correspondingly, a first internal thread matching the first external thread is provided on the inner circumferential surface of the adjusting member, so that the first connecting section is inserted into the inner side of the adjusting member, and the adjusting member is a structure screwed to the outer side of the first connecting section, which is conducive to setting the main body of the first connecting section as a solid structure, and further improving the structural strength of the first connecting section of the connecting part to reduce the risk of breakage of the connecting part during use.

[0011] In some embodiments, the diameter of the body portion is greater than or equal to the diameter of the second connecting segment.

[0012] In the above technical solution, by setting the diameter of the main body of the first connecting segment to be greater than or equal to the diameter of the second connecting segment, the diameter of the area of ​​the first connecting segment where the first external thread is not provided is also greater than or equal to the diameter of the second connecting segment, thereby facilitating the improvement of the overall structural strength of the first connecting segment and reducing the risk of the first connecting segment of the connecting portion breaking during use.

[0013] In some embodiments, the clamping portion is detachably connected to the second connecting section.

[0014] In the above technical solution, by setting the clamping portion of the locking piece to be detachably connected to the second connecting section of the connecting part, the locking piece can be assembled by inserting the end of the connecting part provided with the clamping portion into the sleeve, and then the clamping portion is assembled to the second connecting section of the connecting part, that is, the second connecting section of the connecting part is first inserted into the sleeve, and then the clamping portion is connected to the second connecting section. The locking mechanism with this structure can, on the one hand, reduce the difficulty of assembling the locking piece and the sleeve, and on the other hand, it is only necessary to set the aperture of the assembly hole of the end of the sleeve close to the clamping portion in the first direction to match the diameter of the second connecting section of the connecting part, and there is no need to enlarge the aperture of the assembly hole of the end of the sleeve close to the clamping portion in the first direction to allow the first connecting section with a larger diameter of the connecting part to pass through, thereby reducing the assembly gap between the second connecting section of the connecting part and the sleeve, alleviating the shaking phenomenon of the locking mechanism during use, and reducing the risk of impurities entering the sleeve through the gap between the second connecting section and the sleeve, thereby effectively improving the service life and reliability of the locking mechanism.

[0015] In some embodiments, the clamping portion is sleeved on the outside of the second connecting section, and the clamping portion is threadedly connected to the second connecting section.

[0016] In the above technical solution, by sleeve-mounting the clamping part on the outside of the second connecting section and adopting a threaded connection structure to connect the clamping part and the second connecting section of the connecting part, it is helpful to reduce the assembly difficulty between the clamping part and the connecting part, and can improve the structural stability and reliability of the clamping part connected to the connecting part.

[0017] In some embodiments, the clamping portion is located outside the sleeve, and the clamping portion protrudes from the outer peripheral surface of the connecting portion along its extension direction, and the extension direction of the clamping portion is perpendicular to the first direction; wherein, the adjusting part can drive the connecting part to rotate by rotating relative to the sleeve, so that the clamping portion is engaged or disengaged with the lock seat, so that the locking part switches between a locked state and an unlocked state.

[0018] In the above technical solution, by arranging the clamping part on the outside of the sleeve, and the clamping part protruding from the outer peripheral surface of the connecting part in its extension direction, the adjusting part can drive the connecting part to rotate when rotating, so that the clamping part can rotate with the connecting part, so that the extension direction of the clamping part can be clamped or released with the lock seat after changing in the plane perpendicular to the first direction, thereby realizing that the locking mechanism can engage with or disengage from the lock seat in the first direction, and the structure is simple and easy to use.

[0019] In some embodiments, the sleeve is provided with a first limiting portion, and the connecting portion is provided with a second limiting portion, and the first limiting portion and the second limiting portion cooperate to limit the rotation angle of the connecting portion.

[0020] In the above technical solution, by correspondingly arranging the first limiting portion and the second limiting portion on the sleeve and the connecting portion respectively, the first limiting portion and the second limiting portion can cooperate to limit the rotation angle of the connecting portion, so that the connecting portion drives the clamping portion to be clamped or released with the lock seat under the cooperation limit of the first limiting portion and the second limiting portion, thereby facilitating the switching of the locking member between the locked state and the unlocked state. The structure is simple and easy to operate, and can alleviate the phenomenon that the clamping portion cannot be clamped with the lock seat due to the large angle of rotation of the clamping portion following the connecting portion, which is beneficial to improving the reliability of the mutual locking between the locking mechanism and the lock seat.

[0021] In some embodiments, the first limiting portion and the second limiting portion are also configured to cooperate with the guiding connecting portion to move along the first direction when the adjusting member rotates relative to the sleeve, so that the locking member moves between the first position and the second position along the first direction; when the locking member is in the first position, the locking member is in a locked state, so that the clamping portion can be clamped with the lock seat; when the locking member is in the second position, the locking member is in an unlocked state, so that the clamping portion can be released from the lock seat.

[0022] In the above technical solution, the first limiting portion and the second limiting portion can cooperate with the guiding connecting portion to move relative to the sleeve in the first direction while limiting the rotation angle of the connecting portion, so that the adjusting member can drive the connecting portion to rotate relative to the sleeve while also driving the locking member to move between the first position and the second position along the first direction, so that the adjusting member can drive the clamping portion to engage with the lock seat while also driving the clamping portion and the lock seat to abut against each other, so as to reduce the size of the gap between the clamping portion and the lock seat, thereby reducing the vibration between the locking mechanism and the lock seat.

[0023] In some embodiments, the first limiting portion is a limiting groove provided on the inner circumference of the sleeve, and the second limiting portion is a protrusion provided on the outer circumference of the connecting portion, and at least a portion of the protrusion is accommodated in the limiting groove.

[0024] In the above technical solution, the first limiting portion and the second limiting portion are respectively a limiting groove arranged on the inner circumferential surface of the sleeve and a protrusion on the outer circumferential surface of the connecting portion. By inserting the protrusion into the limiting groove, the rotation angle of the connecting portion is limited under the restriction of the limiting groove, and the protrusion can be guided by the limiting groove to enable the connecting portion to rotate relative to the sleeve and move along the first direction relative to the sleeve at the same time. The structure is simple, easy to implement, and has high stability.

[0025] In some embodiments, the limiting groove includes a first groove section, a second groove section and a third groove section connected in sequence, the first groove section and the third groove section both extend along the first direction, the first groove section and the third groove section are arranged at intervals along the circumference of the connecting portion, and the first groove section and the third groove section are arranged at intervals along the first direction, along the first direction, the third groove section is closer to the clamping portion than the first groove section; when the locking member is in the first position, the protrusion is located in the first groove section, and when the locking member is in the second position, the protrusion is located in the third groove section.

[0026] In the above technical solution, by configuring the first and third groove sections of the limiting groove to extend in the first direction, and the first and third groove sections to be spaced apart in the first direction and in the circumferential direction of the connecting portion, so that the second groove section is a spiral groove connecting the first and third groove sections, the protrusion of the connecting portion can only move in the first direction following the extension direction of the first and second groove sections when located in the first and third groove sections, and the protrusion of the connecting portion can both rotate relative to the sleeve and move relative to the sleeve in the first direction following the extension direction of the second groove section when located in the second groove section, thereby limiting the rotation angle of the locking member and enabling movement between the first position and the second position in the first direction. In addition, by configuring the third groove section to be closer to the engaging portion than the first groove section in the first direction, the engaging portion can engage with the lock seat and be closer to the sleeve when the protrusion is located in the first groove section, so that the engaging portion and the lock seat can abut against each other in the first direction.

[0027] In some embodiments, the limiting groove passes through the outer circumferential surface of the sleeve along the radial direction of the sleeve.

[0028] In the above technical solution, by setting the limit groove as a structure that passes through the outer circumference of the sleeve from the inner circumference of the sleeve, on the one hand, the limit groove can be processed from the outer circumference of the sleeve, which is conducive to reducing the difficulty of setting the limit groove on the sleeve. On the other hand, the groove depth of the limit groove can be increased to improve the stability of the mutual cooperation between the protrusion on the connecting part and the limit groove.

[0029] In some embodiments, the locking mechanism further includes an anti-loosening component; the anti-loosening component is disposed between the sleeve and the adjusting member, and the anti-loosening component is used to selectively lock the adjusting member and the sleeve to limit the adjusting member from rotating relative to the sleeve.

[0030] In the above technical solution, the locking mechanism is also provided with an anti-loosening component, which can selectively lock the adjusting part and the sleeve by arranging the anti-loosening component between the sleeve and the adjusting part, that is, when the anti-loosening component releases the sleeve and the adjusting part, the anti-loosening component can allow the adjusting part to rotate relative to the sleeve, so as to drive the locking part to move relative to the sleeve, so that the locking part and the lock seat are engaged or disengaged, and when the anti-loosening component locks the sleeve and the adjusting part, the anti-loosening component can limit the rotation of the adjusting part relative to the sleeve, thereby alleviating the phenomenon of engagement failure between the locking part and the lock seat caused by erroneous rotation of the adjusting part, thereby improving the locking effect between the locking part and the lock seat, which is beneficial to improving the stability and reliability of the mutual locking between the locking mechanism and the lock seat.

[0031] In some embodiments, the anti-loosening assembly includes a first clutch member and a second clutch member; the first clutch member is arranged on the sleeve; the second clutch member is arranged on the adjusting member; wherein the first clutch member and the second clutch member are configured to: limit the adjusting member from rotating relative to the sleeve when they are engaged with each other; and allow the adjusting member to rotate relative to the sleeve when they are disengaged from each other.

[0032] In the above technical solution, the anti-loosening component is provided with a first clutch member and a second clutch member that can be engaged with and disengaged from each other, and the first clutch member and the second clutch member are respectively provided on the sleeve and the adjusting member, so that the adjusting member can be restricted from rotating relative to the sleeve by engaging with the first clutch member and the second clutch member, and the adjusting member can be rotated relative to the sleeve when the first clutch member and the second clutch member are disengaged from each other, so as to realize the function of the anti-loosening component to selectively lock the adjusting member and the sleeve.

[0033] In some embodiments, the first clutch member and the second clutch member are arranged along the first direction; wherein, the first clutch member is fixed to the sleeve, the second clutch member is circumferentially locked with the adjusting member, and the second clutch member is movably arranged on the adjusting member along the first direction so that the second clutch member can be engaged with or disengaged from the first clutch member.

[0034] In the above technical solution, the first clutch member and the second clutch member are arranged along the first direction, and the second clutch member is movably provided on the adjusting member along the first direction. By fixing the first clutch member to the sleeve and setting the second clutch member to a structure circumferentially locked with the adjusting member, the second clutch member and the first clutch member can be snapped into or disengaged from each other by moving the second clutch member, so as to limit the adjusting member from rotating relative to the sleeve or allow the adjusting member to rotate relative to the sleeve. The anti-loosening component of this structure is simple in structure and easy to operate and implement.

[0035] In some embodiments, the adjusting member has a guide section, and the second clutch member is movably mounted on the outside of the guide section along the first direction; wherein the cross-section of the guide section perpendicular to the first direction is polygonal, and the outer peripheral surface of the guide section fits with the inner peripheral surface of the second clutch member to achieve circumferential locking of the second clutch member and the adjusting member.

[0036] In the above technical solution, the guide section of the adjusting member is set to a structure with a polygonal cross-section perpendicular to the first direction, and the second clutch member is movably sleeved on the outside of the guide section along the first direction, and the inner circumferential surface of the second clutch member is set to a structure that fits with the outer circumferential surface of the guide section, so that the projection shape of the inner circumferential surface of the second clutch member in the first direction is the same as the shape of the cross-section of the guide section perpendicular to the first direction, and both are polygonal, thereby achieving that the second clutch member can be circumferentially locked with the adjusting member but can move relative to the adjusting member along the first direction, and the structure is simple and easy to manufacture.

[0037] In some embodiments, along the first direction, a first tooth-shaped portion is provided at one end of the first clutch member facing the second clutch member, and a second tooth-shaped portion is provided at one end of the second clutch member facing the first clutch member. The second tooth-shaped portion is used to engage with the first tooth-shaped portion to achieve a snap-fit ​​fit between the second clutch member and the first clutch member.

[0038] In the above technical solution, a first toothed portion is provided on one end of the first clutch member facing the second clutch member, and a second toothed portion is correspondingly provided on one end of the second clutch member facing the first clutch member, so that when the second clutch member moves in the first direction, the second toothed portion can engage or disengage with the first toothed portion, thereby achieving a snap-fit ​​or disengagement between the second clutch member and the first clutch member. When the first toothed portion and the second toothed portion are engaged with each other, the first clutch member and the second clutch member can cooperate to restrict the relative rotation of the adjustment member relative to the sleeve. The structure is simple and easy to implement. In addition, by respectively providing the first toothed portion and the second toothed portion on the first clutch member and the second clutch member, the difficulty of snap-fitting and disengaging the first clutch member and the second clutch member can be reduced, which is conducive to the mutual engagement or disengagement of the first clutch member and the second clutch member.

[0039] In some embodiments, along the first direction, a first inclined surface is formed on one end of the first clutch member facing the second clutch member, and a second inclined surface is formed on one end of the second clutch member facing the first clutch member, and the second inclined surface is matched with the first inclined surface; wherein the first tooth-shaped portion is arranged on the first inclined surface, and the second tooth-shaped portion is arranged on the second inclined surface.

[0040] In the above technical solution, a first inclined surface is provided at one end of the first clutch member facing the second clutch member, and the first tooth-shaped portion is provided on the first inclined surface. Correspondingly, a second inclined surface matching the first inclined surface is provided at one end of the second clutch member facing the first clutch member, and the second tooth-shaped portion is provided on the second inclined surface. This structure can realize that the first tooth-shaped portion and the second tooth-shaped portion are inclined structures that match each other, thereby playing a certain guiding role and facilitating the mutual engagement of the first tooth-shaped portion and the second tooth-shaped portion.

[0041] In some embodiments, the first inclined surface is a concave surface provided on the first clutch member, and the second inclined surface is a convex surface provided on the second clutch member.

[0042] In the above technical solution, by setting the first inclined surface as a concave surface and the second inclined surface as a convex surface, the second clutch component can be inserted into the first clutch component when the second tooth-shaped portion of the second clutch component is engaged with the first tooth-shaped portion of the first clutch component, thereby facilitating the improvement of the stability and reliability of the mutual engagement between the second clutch component and the first clutch component, and reducing the phenomenon of slippage between the second clutch component and the first clutch component when they are engaged with each other.

[0043] In some embodiments, the anti-loosening assembly further includes an elastic member; the elastic member is disposed between the sleeve and the second clutch member, and the elastic member is configured to drive the second clutch member to move along the first direction toward the first clutch member so that the second clutch member is engaged with the first clutch member.

[0044] In the above technical solution, the anti-loosening component is also provided with an elastic member, which is arranged between the sleeve and the second clutch member. The elastic member can apply a force in the first direction toward the first clutch member to the second clutch member, so that the first clutch member and the second clutch member are engaged with each other. The anti-loosening component with such a structure can, on the one hand, further improve the stability of the mutual engagement of the first clutch member and the second clutch member, so as to reduce the phenomenon of accidental disengagement of the first clutch member and the second clutch member. On the other hand, after the second clutch member and the first clutch member are disengaged from each other, the second clutch member and the first clutch member can be automatically engaged through the elastic member, without manual intervention, which is convenient for operation and use.

[0086] With technological advancements and the rapid development of new energy vehicles, electric vehicles are gaining increasing market share and frequency of use. Electric commercial vehicles, such as heavy-duty and light-duty electric trucks, are gradually appearing in various application scenarios, and battery swap stations have been built to accommodate these vehicles.

[0087] In the field of new energy vehicles, electric trucks consume more energy than ordinary passenger cars due to their heavy loads and long driving range. Therefore, to maintain battery life, electric trucks require frequent battery swaps. During this process, the locking, securing, and detaching of the battery from the vehicle are key concerns. To achieve this, the current method primarily involves installing a lock seat on the vehicle and a corresponding locking mechanism on the battery. The locking mechanism's adjustment member can drive the locking member of the locking mechanism to lock or unlock the lock seat, completing the vehicle's battery swapping function. However, the locking member and the adjusting member of the locking mechanism usually adopt a threaded connection structure, so that the adjusting member can drive the locking member to move or rotate to achieve locking or unlocking of the locking member and the lock seat, and the locking member needs to bear the weight of the battery, so that the depth of the thread set on the locking member is limited by the structural strength requirement of the locking member, resulting in the locking member being prone to breakage during use, or easily causing the teeth to slip between the locking member and the adjusting member, thereby causing the risk of connection failure between the locking member and the adjusting member, resulting in a shorter service life and lower reliability of the locking mechanism between the battery and the vehicle, causing inconvenience in battery replacement of electrical equipment and safety hazards in use.

[0088] Based on the above considerations, in order to solve the technical problems such as the short service life and low reliability of the locking mechanism between the battery and the vehicle, an embodiment of the present application provides a locking mechanism, which includes a sleeve, a locking member and an adjusting member. The locking member is movably arranged on the sleeve, and the locking member has a locked state and an unlocked state. The locking member is configured to engage with the lock seat when in the locked state so that the locking mechanism and the lock seat engage along the first direction. The locking member is configured to release the engagement with the lock seat when in the unlocked state to allow the locking mechanism and the lock seat to disengage along the first direction. The adjusting member is rotatably connected to the sleeve around an axis extending along the first direction. The adjusting member is configured to drive the locking member to move relative to the sleeve when rotating relative to the sleeve, so that the locking member switches between the locked state and the unlocked state. The locking member includes a connecting portion and a clamping portion that are interconnected. The connecting portion has a first connecting segment and a second connecting segment arranged along a first direction. The first connecting segment is threadedly connected to the adjusting member. The clamping portion is connected to an end of the second connecting segment away from the first connecting segment. The clamping portion is used to clamp with the lock seat. The diameter of the first connecting segment is larger than the diameter of the second connecting segment.

[0102] According to some embodiments of the present application, with reference to FIG2 , and further with reference to FIG4 , FIG5 , FIG6 , FIG7 , and FIG8 , FIG4 is a schematic structural diagram of a locking mechanism 10 provided in some embodiments of the present application, FIG5 is an exploded structural diagram of a locking mechanism 10 provided in some embodiments of the present application, FIG6 is a cross-sectional view of a locking mechanism 10 provided in some embodiments of the present application, FIG7 is a cross-sectional view of a locking member 12 of a locking mechanism 10 provided in some embodiments of the present application, and FIG8 is a schematic structural diagram of a connecting portion 121 of a locking member 12 of a locking mechanism 10 provided in some embodiments of the present application. The present application provides a locking mechanism 10 for engaging with or disengaging from a lock base 300 along a first direction X, the locking mechanism 10 comprising a sleeve 11 , a locking member 12 , and an adjusting member 13 . The locking member 12 is movably disposed on the sleeve 11. The locking member 12 has a locked state and an unlocked state. When in the locked state, the locking member 12 is configured to engage with the lock base 300 to engage the locking mechanism 10 with the lock base 300 in the first direction X. When in the unlocked state, the locking member 12 is configured to disengage from the lock base 300 to allow the locking mechanism 10 to disengage from the lock base 300 in the first direction X. The adjusting member 13 is rotatably connected to the sleeve 11 about an axis extending in the first direction X. The adjusting member 13 is configured to drive the locking member 12 to move relative to the sleeve 11 when rotating relative to the sleeve 11, thereby switching the locking member 12 between the locked state and the unlocked state. The locking member 12 includes a connecting portion 121 and a clamping portion 122 that are interconnected. The connecting portion 121 has a first connecting segment 1211 and a second connecting segment 1212 arranged along the first direction X. The first connecting segment 1211 is threadedly connected to the adjusting member 13. The clamping portion 122 is connected to one end of the second connecting segment 1212 away from the first connecting segment 1211. The clamping portion 122 is used to clamp with the lock seat 300. The diameter of the first connecting segment 1211 is larger than the diameter of the second connecting segment 1212.

[0103] Among them, the locking member 12 is used to engage or disengage with the lock base 300, so that the locking mechanism 10 can engage or disengage with the lock base 300 along the first direction X through the locking member 12, thereby realizing locking or unlocking between the locking mechanism 10 and the lock base 300.

[0104] The locking member 12 is movable relative to the sleeve 11, such that the locking member 12 has a locked state in which it can be engaged with the lock base 300 and an unlocked state in which it can be released from the lock base 300. Exemplarily, the locking member 12 includes a connecting portion 121 and a clamping portion 122 that are interconnected. The connecting portion 121 is a cylindrical structure extending along the first direction X and is inserted into the sleeve 11 along the first direction X. The first connecting section 1211 of the connecting portion 121 is threadedly connected to the adjusting member 13. The clamping portion 122 is connected to an end of the second connecting section 1212 that is away from the first connecting section 1211. The clamping portion 122 functions to be mutually engaged with the lock base 300. The extending direction of the clamping portion 122 is perpendicular to the first direction X, so that the locking member 12 has an irregular structure that can rotate about an axis extending in the first direction X. Therefore, rotating the connecting portion 121 can drive the clamping portion 122 to rotate, so that the clamping portion 122 can be engaged with or released from the lock base 300. Of course, in other embodiments, the engaging portion 122 of the locking member 12 may also be a retractable structure in a direction perpendicular to the first direction X, so that the locking member 12 can be engaged with or disengaged from the lock base 300 through the engaging portion 122 .

[0105] The connecting portion 121 has a first connecting segment 1211 and a second connecting segment 1212 arranged along the first direction X, that is, the connecting portion 121 includes two segments connected to each other in the first direction X, namely the first connecting segment 1211 and the second connecting segment 1212, wherein the segment of the connecting portion 121 used to connect to the adjusting member 13 is the first connecting segment 1211, and the segment of the connecting portion 121 used to connect to the clamping portion 122 is the second connecting segment 1212.

[0106] The first connecting section 1211 is threadedly connected to the adjusting member 13, that is, the first connecting section 1211 is screwed to the adjusting member 13. The first connecting section 1211 can be inserted into the adjusting member 13, that is, the first connecting section 1211 has an external thread, the adjusting member 13 has an internal thread, and the locking member 12 is screwed into the adjusting member 13. Alternatively, the adjusting member 13 can be inserted into the first connecting section 1211, that is, the first connecting section 1211 has an internal thread, the adjusting member 13 has an external thread, and the adjusting member 13 is screwed into the first connecting section 1211. For example, in Figures 6 and 7, the first connecting section 1211 of the connecting portion 121 is inserted into the adjusting member 13, so that the adjusting member 13 is screwed to the outside of the first connecting section.

[0107] The adjusting member 13 is configured to drive the locking member 12 to move relative to the sleeve 11 when rotating relative to the sleeve 11, so that the locking member 12 switches between the locked state and the unlocked state. That is, by rotating the adjusting member 13 relative to the sleeve 11, the adjusting member 13 can drive the locking member 12 to move relative to the sleeve 11, so that the locking member 12 switches between the locked state and the unlocked state. For example, in Figures 4 and 6, rotating the adjusting member 13 can drive the connecting portion 121 of the locking member 12 to rotate relative to the sleeve 11, so that the connecting portion 121 drives the engaging portion 122 to rotate, thereby enabling the engaging portion 122, whose extending direction is perpendicular to the first direction X, to rotate within a plane perpendicular to the first direction X, so that the engaging portion 122 can engage or disengage with the lock base 300, so that the locking member 12 switches between the locked state and the unlocked state.

[0108] Optionally, the adjusting member 13 is rotatable around an axis extending along the first direction X and is axially locked in the sleeve 11 along the first direction X. Referring to Figures 5 and 6, and further referring to Figure 9, Figure 9 is a partial enlarged view of point A of the locking mechanism 10 shown in Figure 6, the adjusting member 13 includes an assembly segment 131 and a guide segment 132 arranged and connected along the first direction X, the assembly segment 131 is threadedly connected to the first connecting segment 1211 of the connecting portion 121, and the guide segment 132 is protruding from one end of the assembly segment 131 away from the clamping portion 122 in the first direction X, wherein the locking mechanism 10 also includes a limit member 14, the limit member 14 is connected to the inner circumferential surface of the sleeve 11, and along the first direction X, the limit member 14 abuts against the end surface of one end of the assembly segment 131 of the adjusting member 13 on which the guide segment 132 is protruding, so as to limit the movement of the adjusting member 13 along the first direction X.

[0109] Exemplarily, the limit member 14 is a retaining ring that is clamped on the inner circumference of the sleeve 11, and the retaining ring surrounds the outer side of the guide section 132. An assembly groove 111 is provided on the inner circumference of the sleeve 11. The assembly groove 111 is an annular groove provided around the guide section 132 of the adjustment member 13, and the limit member 14 is clamped in the assembly groove 111.

[0110] In Figures 4, 5 and 6, the first connecting section 1211 of the connecting portion 121 extends out of the sleeve 11 along the first direction X, so that the clamping portion 122 is located on the outside of the sleeve 11 in the first direction X. The sleeve 11 is provided with an assembly hole 112 for the second connecting section 1212 of the connecting portion 121 to pass through, and the clamping portion 122 is connected to one end of the second connecting section 1212 passing through the assembly hole 112.

[0111] The diameter of the first connecting segment 1211 is greater than the diameter of the second connecting segment 1212, that is, the outer diameter of the first connecting segment 1211 is greater than the outer diameter of the second connecting segment 1212. It should be noted that in the embodiment where the first connecting segment 1211 is provided with external threads, the diameter of the portion with the largest outer diameter of the first connecting segment 1211 is greater than the diameter of the second connecting segment 1212. As shown in Figures 6 and 7, the diameter of the first connecting segment 1211 is D1, and the diameter of the second connecting segment 1212 is D2. In other words, the diameter D1 of the first connecting segment 1211 is greater than the diameter D2 of the second connecting segment 1212. It should be noted that the diameter D1 of the first connecting segment 1211 is the largest outer diameter of the first connecting segment 1211.

[0112] For example, the diameter D1 of the first connecting segment 1211 may be 1 mm, 1.2 mm, 1.5 mm, 1.8 mm, 2 mm, 2.2 mm, 2.5 mm, 2.8 mm, 3 mm, 3.5 mm, or 4 mm larger than the diameter D2 of the second connecting segment 1212 .

[0113] In this embodiment, the locking mechanism 10 is provided with a locking member 12 and an adjusting member 13. The locking member 12 includes a connecting portion 121 and a clamping portion 122. By threading the first connecting section 1211 of the connecting portion 121 with the adjusting member 13, the connecting portion 121 can be driven to move relative to the sleeve 11 when the adjusting member 13 is rotated, so as to further drive the clamping portion 122 to rotate around an axis extending along the first direction X, thereby realizing the switching of the locking member 12 between the locked state and the unlocked state, so that the clamping portion 122 can be clamped or released with the lock seat 300, thereby realizing the engagement or disengagement of the locking mechanism 10 with the lock seat 300 along the first direction X, wherein the diameter of the first connecting section 1211 of the connecting portion 121 for threading with the adjusting member 13 is set It is larger than the diameter of the second connecting section 1212, so that while improving the structural strength of the first connecting section 1211 of the connecting part 121, the thread depth on the first connecting section 1211 can be further increased. On the one hand, it can improve the structural strength of the area where the connecting part 121 is provided with threads, enhance the force-bearing capacity, and reduce the risk of the connecting part 121 breaking during use. On the other hand, it can improve the structural stability of the mutual threaded connection between the first connecting section 1211 and the adjusting part 13, which is conducive to alleviating the phenomenon of slipping or damage to the thread structure between the connecting part 121 of the locking part 12 and the adjusting part 13, so as to reduce the risk of failure of the threaded connection between the locking part 12 and the adjusting part 13, thereby helping to improve the service life and reliability of the locking mechanism 10.

[0114] According to some embodiments of the present application, as shown in Figures 6, 7, and 8, the first connecting section 1211 includes a main body 1211a and a first external thread 1211b. The main body 1211a is connected to one end of the second connecting section 1212. The first external thread 1211b is protruded from the outer circumference of the main body 1211a. The outer diameter of the first external thread 1211b is equal to the diameter of the first connecting section 1211. A first internal thread 133 is provided on the inner circumference of the adjusting member 13, and the first internal thread 133 is configured to cooperate with the first external thread 1211b.

[0115] Among them, the first connecting section 1211 is formed by a main body 1211a connected to the second connecting section 1212 and a first external thread 1211b surrounding and protruding on the outer peripheral surface of the main body 1211a. The main body 1211a and the second connecting section 1212 are both cylindrical structures extending along the first direction X, and one end of the main body 1211a is connected to one end of the second connecting section 1212.

[0116] For example, in Figures 7 and 8, the main body 1211a and the first external thread 1211b are integrally formed. Similarly, the main body 1211a and the second connecting section 1212 are also integrally formed. For example, the main body 1211a and the second connecting section 1212 can be made by an integral molding process such as casting or turning. Of course, in other embodiments, the main body 1211a and the second connecting section 1212 can also be separate structures, and the main body 1211a can be connected to the second connecting section 1212 by welding or threading.

[0117] A first internal thread 133 is provided on the inner circumferential surface of the adjusting member 13, that is, a channel for inserting the first connecting section 1211 of the connecting portion 121 is provided at one end of the adjusting member 13 close to the clamping portion 122 in the first direction X, and a first internal thread 133 is formed on the wall surface of the channel, so that the first external thread 1211b of the first connecting section 1211 can cooperate with the first internal thread 133 of the adjusting member 13 to realize that the first connecting section 1211 is screwed into the adjusting member 13, wherein, in Figures 5 and 6, the channel is provided on the end surface of the assembly section 131 of the adjusting member 13 away from the guide section 132 in the first direction X, and the first internal thread 133 is provided on the assembly section 131 of the adjusting member 13, so that the first connecting section 1211 is screwed into the assembly section 131 of the adjusting member 13.

[0118] In this embodiment, the first connecting section 1211 is provided with a main body 1211a and a first external thread 1211b, and the first external thread 1211b is a structure protruding from the outer peripheral surface of the main body 1211a. Correspondingly, the inner peripheral surface of the adjusting member 13 is provided with a first internal thread 133 that cooperates with the first external thread 1211b, so that the first connecting section 1211 is inserted into the inner side of the adjusting member 13, and the adjusting member 13 is a structure screwed to the outer side of the first connecting section 1211, which is conducive to setting the main body 1211a of the first connecting section 1211 to a solid structure, thereby further improving the structural strength of the first connecting section 1211 of the connecting portion 121, so as to reduce the risk of breakage of the connecting portion 121 during use.

[0119] In some embodiments, as shown in FIG. 7 and FIG. 8 , the diameter of the main body portion 1211 a is greater than or equal to the diameter of the second connecting segment 1212 .

[0120] In Figures 7 and 8, the diameter of the second connecting segment 1212 is D2, and the diameter of the main body 1211a is D3, that is, the diameter D3 of the main body 1211a is greater than or equal to the diameter D2 of the second connecting segment 1212. In other words, along the radial direction of the first connecting segment 1211, the main body 1211a of the first connecting segment 1211 protrudes from the outer peripheral surface of the second connecting segment 1212 or is flush with each other.

[0121] In this embodiment, by setting the diameter of the main body 1211a of the first connecting segment 1211 to be greater than or equal to the diameter of the second connecting segment 1212, the diameter of the area of ​​the first connecting segment 1211 where the first external thread 1211b is not provided is also greater than or equal to the diameter of the second connecting segment 1212, thereby facilitating the improvement of the overall structural strength of the first connecting segment 1211 and reducing the risk of the first connecting segment 1211 of the connecting portion 121 breaking during use.

[0122] According to some embodiments of the present application, referring to FIG. 5 , FIG. 6 and FIG. 7 , the clamping portion 122 is detachably connected to the second connecting section 1212 .

[0123] The clamping portion 122 may be detachably connected to one end of the second connecting section 1212 in various structures. For example, the clamping portion 122 may be detachably connected to the second connecting section 1212 by clamping, threaded connection, or other structures.

[0124] In this embodiment, by setting the clamping portion 122 of the locking member 12 to be detachably connected to the second connecting section 1212 of the connecting portion 121, the locking member 12 can be assembled by inserting the end of the connecting portion 121 provided with the clamping portion 122 into the sleeve 11, and then assembling the clamping portion 122 to the second connecting section 1212 of the connecting portion 121, that is, the second connecting section 1212 of the connecting portion 121 is first inserted into the sleeve 11, and then the clamping portion 122 is connected to the second connecting section 1212. The locking mechanism 10 with such a structure can, on the one hand, reduce the difficulty of assembling the locking member 12 and the sleeve 11, and on the other hand, it only needs to move the sleeve 11 close to the clamping portion in the first direction X. The aperture of the assembly hole 112 at one end of the part 122 is set to match the diameter of the second connecting section 1212 of the connecting part 121. There is no need to enlarge the aperture of the assembly hole 112 at one end of the sleeve 11 close to the clamping part 122 in the first direction X to allow the first connecting section 1211 with a larger diameter of the connecting part 121 to pass through, which is beneficial to reducing the assembly gap between the second connecting section 1212 of the connecting part 121 and the sleeve 11, which is beneficial to alleviate the shaking phenomenon of the locking mechanism 10 during use, and can reduce the risk of impurities entering the sleeve 11 through the gap between the second connecting section 1212 and the sleeve 11, thereby effectively improving the service life and reliability of the locking mechanism 10.

[0125] In some embodiments, referring to FIG. 5 and FIG. 7 , the clamping portion 122 is sleeved on the outside of the second connecting section 1212 , and the clamping portion 122 is threadedly connected to the second connecting section 1212 .

[0126] Among them, in Figures 7 and 8, the clamping portion 122 is provided with a first through hole 1221 for the second connecting section 1212 to pass through, and a second internal thread 1222 is provided on the hole wall surface of the first through hole 1221. Correspondingly, the second connecting section 1212 is inserted into the first through hole 1221 of the clamping portion 122, and a second external thread 1212a is formed on the outer peripheral surface of the part of the second connecting portion 121 inserted into the first through hole 1221, so that the clamping portion 122 can be threadedly connected to the outer side of the second connecting section 1212.

[0127] In this embodiment, by sleeve-mounting the clamping portion 122 on the outside of the second connecting section 1212 and adopting a threaded connection structure to connect the clamping portion 122 and the second connecting section 1212 of the connecting portion 121, it is beneficial to reduce the assembly difficulty between the clamping portion 122 and the connecting portion 121, and can improve the structural stability and reliability of the clamping portion 122 connected to the connecting portion 121.

[0128] According to some embodiments of the present application, as shown in Figures 4, 5, 6, and 7, the engaging portion 122 is located outside the sleeve 11, and the engaging portion 122 protrudes from the outer circumferential surface of the connecting portion 121 along its extension direction. The extension direction of the engaging portion 122 is perpendicular to the first direction X. The adjusting member 13 can drive the connecting portion 121 to rotate by rotating relative to the sleeve 11, so that the engaging portion 122 engages or disengages with the lock seat 300, thereby switching the locking member 12 between a locked state and an unlocked state.

[0129] Among them, the clamping portion 122 is located outside the sleeve 11, that is, the connecting portion 121 has a portion that is not inserted into the sleeve 11, and the clamping portion 122 is connected to one end of the portion of the second connecting section 1212 of the connecting portion 121 that is not inserted into the sleeve 11, so that the clamping portion 122 is arranged at intervals with the sleeve 11 along the first direction X.

[0130] The clamping portion 122 protrudes from the outer peripheral surface of the connecting portion 121 along its extension direction. The extension direction of the clamping portion 122 is perpendicular to the first direction X. That is, in the extension direction of the clamping portion 122, the clamping portion 122 extends beyond the outer peripheral surface of the connecting portion 121. For example, in Figures 4 and 6, the extension direction of the clamping portion 122 is perpendicular to the first direction X, so that the clamping portion 122 and the connecting portion 121 form a "T"-shaped structure. Of course, in other embodiments, the clamping portion 122 and the connecting portion 121 may also form an "L"-shaped structure.

[0131] The adjusting member 13 can drive the connecting portion 121 to rotate by rotating relative to the sleeve 11, so that the clamping portion 122 is clamped or released from the lock seat 300, so that the locking member 12 switches between the locked state and the unlocked state, that is, when the adjusting member 13 rotates relative to the sleeve 11, it can drive the clamping portion 122 to rotate around the axis extending along the first direction X through the connecting portion 121, so that the extension direction of the clamping portion 122 can be changed within a plane perpendicular to the first direction X, so that the clamping portion 122 can overlap the lock seat 300 or release the overlap from the lock seat 300, so that the clamping portion 122 can be clamped or released from the lock seat 300.

[0132] Exemplarily, the projection of the clamping portion 122 in the first direction X is rectangular, the length direction of the rectangle is the extension direction of the clamping portion 122 , and the clamping portion 122 extends beyond the outer circumference of the connecting portion 121 in the length direction of the rectangle.

[0133] In some embodiments, refer to FIG. 4 and further refer to FIG. 10 , which is a schematic diagram of the connection between the locking mechanism 10 and the lock base 300 provided in some embodiments of the present application. When the locking mechanism 10 and the lock base 300 are in engagement with each other, the locking mechanism 10 and the lock base 300 are locked.

[0134] Among them, the cross-section of the locking hole 310 is rectangular. When the extension direction of the clamping portion 122 is consistent with the length direction of the cross-section of the locking hole 310, the clamping portion 122 can be inserted into the locking hole 310 or can be withdrawn from the locking hole 310. When the clamping portion 122 passes through the locking hole 310 and the extension direction of the clamping portion 122 intersects with the length direction of the cross-section of the locking hole 310, the clamping portion 122 can be engaged with the surface of the lock seat 300 on the side facing away from the sleeve 11.

[0135] Optionally, as shown in Figures 4 and 6 , a clamping surface 113 is further formed at one end of the sleeve 11 near the clamping portion 122 along the first direction X. The clamping surface 113 is configured to abut against a side of the lock base 300 facing the sleeve 11 when the locking member 12 is in the locked state, and the assembly hole 112 passes through the clamping surface 113 along the first direction X. When the locking mechanism 10 is engaged with the lock base 300 along the first direction X, the clamping portion 122 and the clamping surface 113 respectively abut against two sides of the lock base 300 in the first direction X. By setting the clamping surface 113 of the sleeve 11 so that it can abut against the side of the lock seat 300 facing the sleeve 11 when the locking member 12 and the lock seat 300 are clamped in the locked state, the locking mechanism 10 can clamp the lock seat 300 in the first direction X through the clamping portion 122 of the locking member 12 and the clamping surface 113 of the sleeve 11, which is beneficial to reduce the shaking phenomenon of the locking mechanism 10 during use, thereby improving the stability of the mutual locking between the locking mechanism 10 and the lock seat 300.

[0136] In this embodiment, by arranging the clamping portion 122 on the outside of the sleeve 11, and the clamping portion 122 protruding from the outer peripheral surface of the connecting portion 121 in its extension direction, the adjusting member 13 can drive the connecting portion 121 to rotate when rotating, so that the clamping portion 122 can rotate with the connecting portion 121, so that the extension direction of the clamping portion 122 is changed in the plane perpendicular to the first direction X and can be clamped or unclamped with the lock seat 300, thereby realizing that the locking mechanism 10 can engage with or disengage from the lock seat 300 in the first direction X, and the structure is simple and easy to use.

[0137] According to some embodiments of the present application, referring to Figures 5, 6, 7 and 8, the sleeve 11 is provided with a first limiting portion 114, and the connecting portion 121 is provided with a second limiting portion 1213. The first limiting portion 114 and the second limiting portion 1213 cooperate to limit the rotation angle of the connecting portion 121.

[0138] Among them, the first limiting portion 114 and the second limiting portion 1213 play the role of cooperating to limit the rotation angle of the connecting portion 121 relative to the sleeve 11. The structures of the first limiting portion 114 and the second limiting portion 1213 can be various. For example, the first limiting portion 114 can be a limiting groove provided on the inner circumference of the sleeve 11, and correspondingly, the second limiting portion 1213 can be a protrusion convexly provided on the outer circumference of the connecting portion 121, and the protrusion is inserted into the limiting groove to cooperate with the rotation of the connecting portion 121. To limit the moving angle, of course, the first limiting portion 114 and the second limiting portion 1213 can also be protrusions, the first limiting portion 114 is protruded at one end of the sleeve 11 in the first direction X, and the second limiting portion 1213 is protruded on the outer peripheral surface of the connecting portion 121. When the connecting portion 121 rotates relative to the sleeve 11, the second limiting portion 1213 can abut against the first limiting portion 114 to limit the rotation angle of the connecting portion 121 through the mutual cooperation of the first limiting portion 114 and the second limiting portion 1213.

[0139] Optionally, the number of the first limiting portion 114 and the second limiting portion 1213 can be one or more. For example, in the embodiment of the present application, as shown in Figures 6 and 8, there are two first limiting portions 114, and correspondingly, there are also two second limiting portions 1213. The two second limiting portions 1213 are respectively arranged on both sides of the connecting portion 121 along the radial direction of the connecting portion 121.

[0140] Exemplarily, the first limiting portion 114 and the second limiting portion 1213 cooperate to limit the rotation angle of the connecting portion 121 relative to the sleeve 11 to 90 degrees, so that the clamping portion 122 can rotate from an angle where the extension direction of the clamping portion 122 and the length direction of the lock hole 310 are parallel to each other to an angle where the extension direction of the clamping portion 122 and the length direction of the lock hole 310 are perpendicular to each other, so as to realize the switching of the locking member 12 between the unlocked state and the locked state.

[0141] In this embodiment, by correspondingly providing the first limiting portion 114 and the second limiting portion 1213 on the sleeve 11 and the connecting portion 121 respectively, the first limiting portion 114 and the second limiting portion 1213 can cooperate to limit the rotation angle of the connecting portion 121, so that the connecting portion 121 drives the clamping portion 122 to be clamped or released with the lock seat 300 under the cooperation restriction of the first limiting portion 114 and the second limiting portion 1213, thereby facilitating the switching of the locking member 12 between the locked state and the unlocked state. The structure is simple and easy to operate, and can alleviate the phenomenon that the clamping portion 122 cannot be clamped with the lock seat 300 due to the excessive rotation angle of the clamping portion 122 following the connecting portion 121, which is beneficial to improving the reliability of the mutual locking between the locking mechanism 10 and the lock seat 300.

[0142] According to some embodiments of the present application, as shown in Figures 6 and 10, the first limiting portion 114 and the second limiting portion 1213 are further configured to cooperate with the guiding connecting portion 121 to move along the first direction X when the adjusting member 13 rotates relative to the sleeve 11, so as to move the locking member 12 between the first position and the 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, so that the engaging portion 122 can 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, so that the engaging portion 122 can be released from the lock base 300.

[0143] Among them, the first limiting portion 114 and the second limiting portion 1213 are further configured to cooperate to guide the connecting portion 121 to move along the first direction X when the adjusting member 13 rotates relative to the sleeve 11, that is, in the process of the adjusting member 13 driving the connecting portion 121 to rotate relative to the sleeve 11, the first limiting portion 114 and the second limiting portion 1213 cooperate to limit the rotation angle of the connecting portion 121 while also guiding the connecting portion 121 to move relative to the sleeve 11 in the first direction X, so that the locking member 12 has two end positions relative to the sleeve 11 in the first direction X, namely the first position and the second position. That is to say, when the adjusting member 13 drives the connecting portion 121 to rotate relative to the sleeve 11, the connecting portion 121 It can also move relative to the sleeve 11 along the first direction X, so that when the connecting portion 121 drives the clamping portion 122 to rotate until the clamping portion 122 can engage with the side of the lock seat 300 away from the sleeve 11, the locking member 12 is in the first position. When the locking member 12 is in the first position, the clamping portion 122 and the clamping surface 113 of the sleeve 11 respectively abut against the two sides of the lock seat 300 in the first direction X. Correspondingly, when the locking member 12 moves to the second position, the projection of the clamping portion 122 in the first direction X is located in the lock hole 310 of the lock seat 300, and the clamping portion 122 and the lock seat 300 are arranged at intervals in the first direction X, so that the locking member 12 can disengage from the lock seat 300 along the first direction X.

[0144] When the adjusting member 13 rotates relative to the sleeve 11, it can not only drive the connecting portion 121 to rotate, but also drive the connecting portion 121 to move along the first direction X. In Figures 6 and 9, the adjusting member 13 and the first connecting portion 121 of the connecting portion 121 are connected by a threaded structure, so that the adjusting member 13 can drive the connecting portion 121 to rotate, and when the circumferential rotation of the connecting portion 121 is restricted, the adjusting member 13 can provide the connecting portion 121 with a feed force along the first direction X, so that the connecting portion 121 can move along the first direction X.

[0145] In this embodiment, the first limiting portion 114 and the second limiting portion 1213 can cooperate with the guiding connecting portion 121 to move relative to the sleeve 11 in the first direction X while limiting the rotation angle of the connecting portion 121, so that the adjusting member 13 can drive the connecting portion 121 to rotate relative to the sleeve 11 while also driving the locking member 12 to move between the first position and the second position along the first direction X, so that the adjusting member 13 can drive the clamping portion 122 to clamp with the lock seat 300 while also driving the clamping portion 122 and the lock seat 300 to abut against each other, so as to reduce the size of the gap between the clamping portion 122 and the lock seat 300, thereby reducing the vibration between the locking mechanism 10 and the lock seat 300.

[0146] According to some embodiments of the present application, referring to Figures 5, 6, 7, and 8, and further referring to Figure 11, which is a schematic structural diagram of the sleeve 11 of the locking mechanism 10 provided in some embodiments of the present application, the first limiting portion 114 is a limiting groove provided on the inner circumference of the sleeve 11, and the second limiting portion 1213 is a protrusion provided on the outer circumference of the connecting portion 121, with at least a portion of the protrusion being accommodated in the limiting groove.

[0147] Among them, the first limiting portion 114 is a limiting groove, and the second limiting portion 1213 is a protrusion. By inserting the protrusion into the limiting groove, the movement trajectory of the protrusion will be restricted and guided by the limiting groove, so that the first limiting portion 114 and the second limiting portion 1213 can cooperate to limit the rotation angle of the connecting portion 121 and move between the first position and the second position along the first direction X.

[0148] 8 , the second position-limiting portion 1213 is protruded from the outer circumference of the main body 1211a of the first connecting section 1211 of the connecting portion 121. Of course, in other embodiments, the second position-limiting portion 1213 may also be protruded from the outer circumference of the second connecting section 1212 of the connecting portion 121.

[0149] It should be noted that, in other embodiments, the first limiting portion 114 and the second limiting portion 1213 may also be other structures. For example, the first limiting portion 114 is a protrusion protruding from the inner circumference of the sleeve 11, and correspondingly, the second limiting portion 1213 is a limiting groove provided on the outer circumference of the connecting portion 121.

[0150] In this embodiment, the first limiting portion 114 and the second limiting portion 1213 are respectively a limiting groove arranged on the inner circumferential surface of the sleeve 11 and a protrusion on the outer circumferential surface of the connecting portion 121. By inserting the protrusion into the limiting groove, the rotation angle of the connecting portion 121 is limited under the restriction of the limiting groove, and the protrusion can enable the connecting portion 121 to rotate relative to the sleeve 11 while moving along the first direction X relative to the sleeve 11 under the guidance of the limiting groove. The structure is simple, easy to implement, and has high stability.

[0151] In some embodiments, referring to FIG. 11 and further to FIG. 12 , FIG. 12 is a cross-sectional view of the sleeve 11 of the locking mechanism 10 provided in some embodiments of the present application. The limiting groove may include a first groove section 1141, a second groove section 1142, and a third groove section 1143, each of which extends in a first direction X. The first groove section 1141 and the third groove section 1143 are spaced apart along the circumference of the connecting portion 121, and the first groove section 1141 and the third groove section 1143 are spaced apart along the first direction X. Along the first direction X, the third groove section 1143 is closer to the engaging portion 122 than the first groove section 1141. When the locking member 12 is in the first position, the protrusion is located in the first groove section 1141. When the locking member 12 is in the second position, the protrusion is located in the third groove section 1143.

[0152] Among them, the first slot segment 1141 and the third slot segment 1143 are arranged at intervals along the circumference of the connecting portion 121, and the first slot segment 1141 and the third slot segment 1143 are arranged at intervals along the first direction X, that is, there is a distance between the first slot segment 1141 and the third slot segment 1143 of the limiting slot in the first direction X, and there is also a distance in the circumferential direction of the connecting portion 121. It should be noted that, since the first groove segment 1141 and the third groove segment 1143 are arranged at intervals in the first direction X and in the circumferential direction of the connecting portion 121, the second groove segment 1142 connecting the first groove segment 1141 and the third groove segment 1143 is a spiral structure surrounding the connecting portion 121, so that when the protrusion is located in the first groove segment 1141 and the third groove segment 1143, the connecting portion 121 can only move along the first direction X under the drive of the adjusting member 13, and when the protrusion is located in the second groove segment 1142, the connecting portion 121 can be driven by the adjusting member 13 to move along the first direction X and rotate around the axis extending along the first direction X.

[0153] When the locking member 12 is in the first position, the protrusion is located in the first groove section 1141, and when the locking member 12 is in the second position, the protrusion is located in the third groove section 1143. That is, when the protrusion of the connecting portion 121 moves from the first groove section 1141 to the third groove section 1143, the locking member 12 can move from the first position to the second position.

[0154] Of course, the structure of the limiting groove is not limited to this. In some embodiments, the limiting groove may also be other structures. For example, the limiting groove extends along the first direction X and has a wider width in the circumferential direction of the connecting portion 121, so that the limiting groove has two opposite groove side walls in the circumferential direction of the connecting portion 121. The two groove side walls are arranged at intervals in the circumferential direction of the connecting portion 121, and the two groove side walls are both used for the protrusion to abut. The protrusion is inserted into the limiting groove, and the protrusion can move between the two groove side walls along the circumference of the connecting portion 121 to limit the rotation angle of the connecting portion 121. When the protrusion abuts against the groove side walls of the limiting groove, the groove side walls of the limiting groove can block the rotation of the connecting portion 121 to limit the rotation angle of the connecting portion 121. After being blocked by the groove side walls of the limiting groove, the protrusion of the connecting portion 121 can move along the first direction X under the guidance of the groove side walls of the limiting groove, so that the connecting portion 121 can move along the first direction X.

[0155] In this embodiment, the first groove section 1141 and the third groove section 1143 of the limiting groove are set to structures that extend along the first direction X, and the first groove section 1141 and the third groove section 1143 are arranged at intervals in the first direction X and the circumferential direction of the connecting portion 121, so that the second groove section 1142 is a spiral groove connected between the first groove section 1141 and the third groove section 1143, so that when the protrusion of the connecting portion 121 is located in the first groove section 1141 and the third groove section 1143, it can only move along the first direction X following the extension direction of the first groove section 1141 and the second groove section 1142, and when the protrusion of the connecting portion 121 is located in the second groove section 1142, it can follow the extension direction of the second groove section 1142 and can both rotate relative to the sleeve 11 and move relative to the sleeve 11 along the first direction X, thereby achieving the limitation of the rotation angle of the locking member 12 and enabling movement between the first position and the second position along the first direction X. In addition, by setting the third groove section 1143 to be closer to the clamping portion 122 than the first groove section 1141 in the first direction X, the clamping portion 122 can be clamped with the lock seat 300 when the protrusion is located in the first groove section 1141 and can be closer to the sleeve 11, so that the clamping portion 122 can abut against each other with the lock seat 300 in the first direction X.

[0156] In some embodiments, as shown in Figures 11 and 12, the limiting groove penetrates the outer circumference of the sleeve 11 along the radial direction of the sleeve 11. In other words, in the depth direction of the limiting groove, the limiting groove penetrates the inner circumference of the sleeve 11 and the outer circumference of the sleeve 11, so that the sleeve 11 has an internal and external through-structure in the area where the limiting groove is provided.

[0157] In this embodiment, by setting the limit groove as a structure that passes through the outer circumference of the sleeve 11 from the inner circumference of the sleeve 11, on the one hand, the limit groove can be processed from the outer circumference of the sleeve 11, which is conducive to reducing the difficulty of setting the limit groove on the sleeve 11. On the other hand, the groove depth of the limit groove can be increased to improve the stability of the mutual cooperation between the protrusion on the connecting part 121 and the limit groove.

[0158] According to some embodiments of the present application, as shown in Figures 5, 6 and 9, the locking mechanism 10 may further include an anti-loosening component 15, which is arranged between the sleeve 11 and the adjusting member 13. The anti-loosening component 15 is used to selectively lock the adjusting member 13 with the sleeve 11 to limit the rotation of the adjusting member 13 relative to the sleeve 11.

[0159] Among them, the anti-loosening component 15 is used to selectively lock the adjusting part 13 and the sleeve 11 to limit the rotation of the adjusting part 13 relative to the sleeve 11. That is, the anti-loosening component 15 can selectively lock or unlock the adjusting part 13 and the sleeve 11. When the anti-loosening component 15 locks the adjusting part 13 and the sleeve 11, the adjusting part 13 cannot rotate relative to the sleeve 11. When the anti-loosening component 15 unlocks the adjusting part 13 and the sleeve 11, the adjusting part 13 can rotate relative to the sleeve 11.

[0160] In this embodiment, the locking mechanism 10 is further provided with an anti-loosening component 15, which can selectively lock the adjusting component 13 with the sleeve 11 by arranging the anti-loosening component 15 between the sleeve 11 and the adjusting component 13, that is, when the anti-loosening component 15 releases the sleeve 11 and the adjusting component 13, the anti-loosening component 15 can allow the adjusting component 13 to rotate relative to the sleeve 11, so as to drive the locking component 12 to move relative to the sleeve 11, so that the locking component 12 and the lock seat 300 are engaged or disengaged, and when the anti-loosening component 15 locks the sleeve 11 and the adjusting component 13, the anti-loosening component 15 can limit the rotation of the adjusting component 13 relative to the sleeve 11, thereby alleviating the phenomenon of the locking failure of the locking component 12 and the lock seat 300 caused by the erroneous rotation of the adjusting component 13, so as to improve the locking effect between the locking component 12 and the lock seat 300, which is beneficial to improving the stability and reliability of the mutual locking of the locking mechanism 10 and the lock seat 300.

[0161] According to some embodiments of the present application, as shown in Figures 5, 6, and 9, the anti-loosening assembly 15 may include a first clutch member 151 and a second clutch member 152. The first clutch member 151 is disposed on the sleeve 11, and the second clutch member 152 is disposed on the adjusting member 13. The first clutch member 151 and the second clutch member 152 are configured to: restrict the adjusting member 13 from rotating relative to the sleeve 11 when engaged with each other; and allow the adjusting member 13 to rotate relative to the sleeve 11 when disengaged from each other.

[0162] The first clutch 151 and the second clutch 152 can restrict the adjustment member 13 from rotating relative to the sleeve 11 when they are engaged with each other. Conversely, when the first clutch 151 and the second clutch 152 are disengaged from each other, the adjustment member 13 can be allowed to rotate relative to the sleeve 11. Optionally, the structures of the first clutch 151 and the second clutch 152 can be various. For example, the first clutch 151 can be fixed to the inner side of the sleeve 11, and the second clutch 152 can be movably arranged on the outer side of the adjusting member 13 along the first direction X and circumferentially locked with the adjusting member 13, that is, the second clutch 152 can move relative to the adjusting member 13 along the first direction X but cannot rotate circumferentially relative to the adjusting member 13, so that when the second clutch 152 moves along the first direction X to engage with the first clutch 151, the first clutch 151 and the second clutch 152 can cooperate to limit the rotation of the adjusting member 13 relative to the sleeve 11; conversely, when the first clutch 151 and the second clutch 152 are disengaged from each other, the adjusting member 13 can be allowed to rotate relative to the sleeve 11. Of course, the first clutch member 151 may also be a structure that is movably disposed in the sleeve 11 along the first direction X and circumferentially locked with the sleeve 11, and correspondingly, the second clutch member 152 is fixedly sleeved on the outside of the adjusting member 13. The anti-loosening assembly 15 may also be a structure in which the first clutch member 151 is fixed in the sleeve 11, the second clutch member 152 is fixedly sleeved on the outside of the adjusting member 13, and the adjusting member 13 is movably disposed in the sleeve 11 along the first direction X, so that movement of the adjusting member 13 in the first direction X can drive the second clutch member 152 to engage with or disengage from the first clutch member 151.

[0163] Of course, the structure of the anti-loosening component 15 is not limited to this. In other embodiments, the anti-loosening component 15 can also be other structures. For example, the anti-loosening component 15 can be a bolt threaded on the sleeve 11. When the bolt is tightened, the bolt can abut against the adjusting part 13 to limit the rotation of the adjusting part 13 relative to the sleeve 11. When the bolt is loosened, the bolt can be separated from the adjusting part 13 to allow the adjusting part 13 to rotate relative to the sleeve 11, thereby realizing that the anti-loosening component 15 can selectively lock the adjusting part 13 and the sleeve 11.

[0164] In this embodiment, the anti-loosening component 15 is provided with a first clutch component 151 and a second clutch component 152 that can be engaged with and disengaged from each other, and the first clutch component 151 and the second clutch component 152 are respectively provided on the sleeve 11 and the adjusting component 13, so that the adjusting component 13 can be restricted from rotating relative to the sleeve 11 by engaging with the first clutch component 151 and the second clutch component 152, and the adjusting component 13 can be rotated relative to the sleeve 11 when the first clutch component 151 and the second clutch component 152 are disengaged from each other, so as to realize the function of the anti-loosening component 15 to selectively lock the adjusting component 13 and the sleeve 11.

[0165] In some embodiments, referring to Figures 5, 6, and 9, the first clutch member 151 and the second clutch member 152 are arranged along the first direction X. The first clutch member 151 is fixed to the sleeve 11, the second clutch member 152 is circumferentially locked with the adjustment member 13, and the second clutch member 152 is movably disposed on the adjustment member 13 along the first direction X, so that the second clutch member 152 can engage or disengage with the first clutch member 151.

[0166] Among them, the first clutch member 151 is fixed to the inner side of the sleeve 11, and the fixed connection structure between the first clutch member 151 and the sleeve 11 can be various. For example, the first clutch member 151 can be fixedly connected to the sleeve 11 by structures such as threaded connection, welding connection, bonding, clamping or interference fit.

[0167] For example, referring to Figures 9 and 12, and further to Figure 13, Figure 13 is a schematic structural diagram of the first clutch member 151 of the anti-loosening assembly 15 of the locking mechanism 10 provided in some embodiments of the present application. A third internal thread 115 is formed on the inner circumferential surface of the sleeve 11, and a third external thread 1511 is formed on the outer circumferential surface of the first clutch member 151. The first clutch member 151 is inserted into the sleeve 11, and the third external thread 1511 cooperates with the third internal thread 115 to thread the first clutch member 151 into the sleeve 11.

[0168] The second clutch member 152 is circumferentially locked with the adjusting member 13 and is movably disposed on the adjusting member 13 along the first direction X. That is, the second clutch member 152 can move relative to the adjusting member 13 along the first direction X but cannot rotate circumferentially relative to the adjusting member 13, so that the second clutch member 152 can engage with or disengage from the first clutch member 151 when moving along the first direction X.

[0169] Exemplarily, the second clutch member 152 is sleeved on the outer side of the guide section 132 of the adjusting member 13 .

[0170] In this embodiment, the first clutch member 151 and the second clutch member 152 are arranged along the first direction X, and the second clutch member 152 is movably provided on the adjusting member 13 along the first direction X. By fixing the first clutch member 151 to the sleeve 11 and setting the second clutch member 152 to a structure circumferentially locked with the adjusting member 13, the second clutch member 152 and the first clutch member 151 can be snapped into or out of engagement by moving the second clutch member 152, so as to limit the adjusting member 13 from rotating relative to the sleeve 11 or allow the adjusting member 13 to rotate relative to the sleeve 11. The anti-loosening component 15 of this structure is simple in structure and easy to operate and implement.

[0171] According to some embodiments of the present application, referring to Figures 5, 6, and 9, and further referring to Figure 14, Figure 14 is a schematic structural diagram of the second clutch member 152 of the anti-loosening assembly 15 of the locking mechanism 10 provided in some embodiments of the present application. The adjusting member 13 has a guide section 132, and the second clutch member 152 is movably mounted on the outer side of the guide section 132 along the first direction X. The cross-section of the guide section 132 perpendicular to the first direction X is polygonal, and the outer circumferential surface of the guide section 132 is aligned with the inner circumferential surface of the second clutch member 152 to achieve circumferential locking of the second clutch member 152 and the adjusting member 13.

[0172] Among them, the guide section 132 is connected to the end of the assembly section 131 of the adjusting member 13 away from the clamping portion 122 in the first direction X, the first clutch member 151 is fixed in the sleeve 11 and is arranged around the guide section 132 of the adjusting member 13, and the second clutch member 152 is movably arranged along the first direction X on the outer side of the guide section 132 of the adjusting member 13, so that the second clutch member 152 can move relative to the adjusting member 13 along the first direction X, so that the second clutch member 152 can be clamped or separated from the first clutch member 151.

[0173] The second clutch member 152 is provided with a second through-hole 1521 for inserting the guide section 132 of the adjustment member 13, so that the second clutch member 152 can be sleeved on the outside of the guide section 132. The cross-section of the guide section 132 perpendicular to the first direction X is polygonal, and the outer circumference of the guide section 132 is aligned with the inner circumference of the second clutch member 152. In other words, the cross-section of the guide section 132 perpendicular to the first direction X is the same as the cross-section of the second through-hole 1521 perpendicular to the first direction X, and both are polygonal. This allows the outer circumference of the guide section 132 to be aligned with the wall surface of the second through-hole 1521 after the guide section 132 is inserted into the second through-hole 1521 of the second clutch member 152.

[0174] For example, in Figures 5 and 14, the cross-section of the guide section 132 perpendicular to the first direction X and the cross-section of the second through hole 1521 perpendicular to the first direction X are both regular hexagons. Of course, in other embodiments, the cross-section of the guide section 132 perpendicular to the first direction X and the cross-section of the second through hole 1521 perpendicular to the first direction X can also be a triangle, a rectangle, a pentagon or a heptagon, etc.

[0175] It should be noted that, in other embodiments, the structure of the circumferential locking between the second clutch member 152 and the guide section 132 of the adjustment member 13 can be various. For example, a spline extending along the first direction X can be convexly provided on the outer peripheral surface of the guide section 132, and correspondingly, a spline groove that cooperates with the spline is provided on the wall surface of the second through hole 1521 of the second clutch member 152.

[0176] In this embodiment, the guide section 132 of the adjusting member 13 is configured to have a polygonal cross-section perpendicular to the first direction X, the second clutch member 152 is movably sleeved on the outside of the guide section 132 along the first direction X, and the inner circumferential surface of the second clutch member 152 is configured to be mutually engaged with the outer circumferential surface of the guide section 132. As a result, the projection shape of the inner circumferential surface of the second clutch member 152 in the first direction X is the same as the cross-section shape of the guide section 132 perpendicular to the first direction X, and both are polygonal. This ensures that the second clutch member 152 can be circumferentially locked with the adjusting member 13 but can move relative to the adjusting member 13 along the first direction X. This results in a simple structure and ease of manufacture.

[0177] According to some embodiments of the present application, referring to Figures 5, 13 and 14, along the first direction X, a first tooth-shaped portion 1512 is provided at one end of the first clutch member 151 facing the second clutch member 152, and a second tooth-shaped portion 1522 is provided at one end of the second clutch member 152 facing the first clutch member 151. The second tooth-shaped portion 1522 is used to engage with the first tooth-shaped portion 1512 to achieve a snap-fit ​​connection between the second clutch member 152 and the first clutch member 151.

[0178] The first toothed portion 1512 is a toothed structure disposed on the end of the first clutch member 151 facing the second clutch member 152 in the first direction X. The multiple teeth of the first toothed portion 1512 are arranged circumferentially of the first clutch member 151, and each tooth extends radially of the first clutch member 151, such that the first toothed portion 1512 is disposed around the guide section 132 of the adjustment member 13. The second toothed portion 1522 is a toothed structure disposed on the end of the second clutch member 152 facing the first clutch member 151 in the first direction X. The multiple teeth of the second toothed portion 1522 are arranged circumferentially of the second clutch member 152, and each tooth extends radially of the second clutch member 152, such that the second toothed portion 1522 is disposed around the guide section 132 of the adjustment member 13. When the second clutch member 152 moves along the first direction X and approaches the first clutch member 151, the second tooth-shaped portion 1522 and the first tooth-shaped portion 1512 can engage with each other, thereby achieving mutual engagement between the second clutch member 152 and the first clutch member 151 to limit the adjustment member 13 from rotating relative to the sleeve 11. Conversely, after the first tooth-shaped portion 1512 and the second tooth-shaped portion 1522 disengage from each other, the adjustment member 13 can be allowed to rotate relative to the sleeve 11.

[0179] It should be noted that, in other embodiments, the first clutch member 151 and the second clutch member 152 can also be other structures. For example, a limiting hole is provided at one end of the first clutch member 151 facing the second clutch member 152 in the first direction X, and a latch is provided at one 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 latch can be inserted into the limiting hole to achieve mutual engagement between the second clutch member 152 and the first clutch member 151, thereby limiting the rotation of the adjusting member 13 relative to the sleeve 11.

[0180] In this embodiment, a first tooth-shaped portion 1512 is provided at one end of the first clutch member 151 facing the second clutch member 152, and correspondingly, a second tooth-shaped portion 1522 is provided at one end of the second clutch member 152 facing the first clutch member 151, so that when the second clutch member 152 moves in the first direction X, the second tooth-shaped portion 1522 can engage with or disengage from the first tooth-shaped portion 1512, thereby realizing the snap-fitting or disengagement of the second clutch member 152 and the first clutch member 151, so that when the first tooth-shaped portion 1512 and the second tooth-shaped portion 1522 are engaged with each other, the first clutch member 151 and the second clutch member 152 can cooperate to limit the rotation of the adjustment member 13 relative to the sleeve 11. The structure is simple and easy to implement. In addition, by respectively arranging the first tooth-shaped portion 1512 and the second tooth-shaped portion 1522 on the first clutch member 151 and the second clutch member 152, the difficulty of engaging and disengaging the first clutch member 151 and the second clutch member 152 can be reduced, which is conducive to the mutual engagement or disengagement of the first clutch member 151 and the second clutch member 152.

[0181] According to some embodiments of the present application, as shown in FIG9 , along the first direction X, a first inclined surface 1513 is formed on one end of the first clutch member 151 facing the second clutch member 152, and a second inclined surface 1523 is formed on one end of the second clutch member 152 facing the first clutch member 151. The second inclined surface 1523 mates with the first inclined surface 1513. The first tooth-shaped portion 1512 is disposed on the first inclined surface 1513, and the second tooth-shaped portion 1522 is disposed on the second inclined surface 1523.

[0182] The second inclined surface 1523 matches the first inclined surface 1513 , that is, the first inclined surface 1513 on the first clutch 151 and the second inclined surface 1523 on the second clutch 152 have the same shape, so that the first inclined surface 1513 can fit the second inclined surface 1523 .

[0183] The first tooth-shaped portion 1512 is disposed on the first inclined surface 1513 , and the second tooth-shaped portion 1522 is disposed on the second inclined surface 1523 . In other words, the first tooth-shaped portion 1512 protrudes from the first inclined surface 1513 , and the second tooth-shaped portion 1522 protrudes from the second inclined surface 1523 .

[0184] In this embodiment, a first inclined surface 1513 is provided at one end of the first clutch member 151 facing the second clutch member 152, and the first tooth-shaped portion 1512 is provided on the first inclined surface 1513. Correspondingly, a second inclined surface 1523 that matches the first inclined surface 1513 is provided at one end of the second clutch member 152 facing the first clutch member 151, and the second tooth-shaped portion 1522 is provided on the second inclined surface 1523. This structure can achieve an inclined structure in which the first tooth-shaped portion 1512 and the second tooth-shaped portion 1522 are matched with each other, thereby playing a certain guiding role and facilitating the mutual engagement of the first tooth-shaped portion 1512 and the second tooth-shaped portion 1522.

[0185] In some embodiments, referring to FIG. 9 , FIG. 13 and FIG. 14 , the first inclined surface 1513 is a concave surface provided on the first clutch member 151 , and the second inclined surface 1523 is a convex surface provided on the second clutch member 152 .

[0186] Among them, the first inclined surface 1513 is a concave surface set on the first clutch member 151, that is, the first inclined surface 1513 is a inclined surface set at one end of the first clutch member 151 facing the second clutch member 152 and concave inward, so that the first inclined surface 1513 is a conical surface concave toward the interior of the first clutch member 151.

[0187] The second inclined surface 1523 is a convex surface provided on the second clutch member 152 , that is, the second inclined surface 1523 is provided on one end of the second clutch member 152 facing the first clutch member 151 and protrudes outward, so that the second inclined surface 1523 is a conical surface protruding toward the outside of the second clutch member 152 .

[0188] In this embodiment, by setting the first inclined surface 1513 as a concave surface and the second inclined surface 1523 as a convex surface, the second clutch component 152 can be inserted into the first clutch component 151 when the second tooth-shaped portion 1522 of the second clutch component 152 is engaged with the first tooth-shaped portion 1512 of the first clutch component 151, thereby facilitating improving the stability and reliability of the mutual engagement between the second clutch component 152 and the first clutch component 151, thereby reducing the phenomenon of slippage between the second clutch component 152 and the first clutch component 151 when they are engaged with each other.

[0189] According to some embodiments of the present application, referring to Figures 5, 6 and 9, the anti-loosening assembly 15 may further include an elastic member 153, which is arranged between the sleeve 11 and the second clutch member 152. The elastic member 153 is configured to drive the second clutch member 152 to move along the first direction X toward the direction close to the first clutch member 151, so that the second clutch member 152 is engaged with the first clutch member 151.

[0190] Among them, the elastic member 153 is arranged between the sleeve 11 and the second clutch member 152, so that the elastic member 153 can provide elastic force for the second clutch member 152, so that the second clutch member 152 has a tendency to move in the first direction X toward the direction close to the first clutch member 151. Therefore, in actual use, it is only necessary to overcome the elastic force of the elastic member 153 and push the second clutch member 152 to disengage from the first clutch member 151 to drive the adjusting member 13 to rotate relative to the sleeve 11, so as to realize the switching of the locking member 12 between the locked state and the unlocked state. After the state switching of the locking member 12 is completed, it is necessary to cancel the force pushing the second clutch member 152 so that the second clutch member 152 can approach and engage with the first clutch member 151 under the elastic force of the elastic member 153, so as to realize the rotation limiting function between the adjusting member 13 and the sleeve 11.

[0191] Alternatively, the elastic member 153 may have various structures. For example, the elastic member 153 may be a spring, a spring sheet, or an elastic rubber disposed between the sleeve 11 and the second clutch member 152. For example, in FIG9 , the elastic member 153 is a spring, and the elastic member 153 is sleeved on the outside of the guide section 132 of the adjustment member 13.

[0192] In this embodiment, the anti-loosening component 15 is also provided with an elastic member 153, which is arranged between the sleeve 11 and the second clutch member 152. The elastic member 153 can apply a force in the first direction X toward the first clutch member 151 to the second clutch member 152, so that the first clutch member 151 and the second clutch member 152 are engaged with each other. The anti-loosening component 15 with such a structure can, on the one hand, further improve the stability of the mutual engagement between the first clutch member 151 and the second clutch member 152, so as to reduce the phenomenon of the first clutch member 151 and the second clutch member 152 being accidentally disengaged. On the other hand, after the second clutch member 152 and the first clutch member 151 are disengaged from each other, the second clutch member 152 and the first clutch member 151 can be automatically engaged through the elastic member 153, without the need for manual intervention, which is convenient for operation and use.

[0193] In some embodiments, referring to Figures 5, 6, and 9, the adjusting member 13 has a guide section 132, and the second clutch member 152 is movably mounted on the outside of the guide section 132 along the first direction X. The elastic member 153 is mounted on the outside of the guide section 132, and the two ends of the elastic member 153 in the first direction X respectively abut against the adjusting member 13 and the second clutch member 152.

[0194] Among them, the structure of the elastic member 153 arranged between the sleeve 11 and the second clutch member 152 can be various. For example, the elastic member 153 can be directly connected to the sleeve 11 and the second clutch member 152 at both ends, or it can be indirectly connected to the sleeve 11 and the second clutch member 152, that is, the elastic member 153 is connected to the sleeve 11 and the second clutch member 152 through other components.

[0195] For example, in Figure 9, one end of the elastic member 153 close to the second clutch member 152 in the first direction X abuts against the second clutch member 152 through a gasket, and one end of the elastic member 153 away from the second clutch member 152 in the first direction X abuts against the limit member 14, so that the elastic member 153 indirectly abuts against the sleeve 11.

[0196] Optionally, as shown in Figures 5, 6 and 9, the anti-loosening assembly 15 may further include a stopper 154. The stopper 154 is disposed in the sleeve 11 and surrounds the outer side of the guide section 132 of the adjustment member 13. The elastic member 153 is sleeved on the outer side of the guide section 132, and one end of the elastic member 153 away from the second clutch member 152 in the first direction X abuts against the limiting member 14 through the stopper 154. The anti-loosening assembly 15 with such a structure is conducive to reducing the difficulty of assembling the elastic member 153 abutting against the limiting member 14 without increasing the size of the limiting member 14, and is conducive to improving the assembly stability of the elastic member 153 between the sleeve 11 and the second clutch member 152, thereby alleviating the phenomenon of the elastic member 153 falling off.

[0197] Among them, the side of the stop block 154 facing away from the second clutch member 152 in the first direction X abuts against the limit member 14, and the stop block 154 and the sleeve 11 can be connected to each other, for example, by welding, bonding or clamping, or they can be unconnected to each other, that is, the stop block 154 is movably arranged in the sleeve 11 along the first direction X.

[0198] Exemplarily, as shown in Figure 9, a slot 1541 is further provided on the side of the block 154 facing the second clutch member 152 in the first direction X, and one end of the elastic member 153 away from the second clutch member 152 in the first direction X is inserted into the slot 1541 to enhance the stability of the elastic member 153 against the block 154.

[0199] In this embodiment, the elastic member 153 is configured to be sleeved on the outside of the guide section 132 of the adjustment member 13, and the second clutch member 152 is movably sleeved on the outside of the guide section 132 along the first direction X. On the one hand, the elastic member 153 is able to apply an elastic force to the second clutch member 152, so that the elastic member 153 drives the second clutch member 152 to move along the first direction X toward the first clutch member 151. On the other hand, the guide section 132 can play a certain guiding role on the elastic member 153, so as to achieve stable compression of the elastic member 153 along the first direction X, which helps to alleviate radial deformation or bending of the elastic member 153, thereby improving the stability and reliability of the elastic member 153.

[0200] According to some embodiments of the present application, referring to Figures 4, 7 and 10, a lock hole 310 for inserting the clamping portion 122 is provided on one side of the lock seat 300 in the first direction X, and the clamping portion 122 has a guide slope 1223, which is configured to guide the clamping portion 122 to be inserted into the lock hole 310.

[0201] For example, in FIG. 7 , guide slopes 1223 are formed on both sides of the clamping portion 122 in the extending direction thereof.

[0202] In this embodiment, a guiding slope 1223 is provided on the clamping portion 122, so that when there is deviation during the process of inserting the clamping portion 122 into the lock hole 310 of the lock seat 300, the locking member 12 can be guided by the guiding slope 1223, thereby facilitating the insertion of the clamping portion 122 of the locking member 12 into the lock seat 300 and improving the reliability of the locking mechanism 10.

[0203] According to some embodiments of the present application, the present application further provides a battery assembly 100 , comprising a battery 20 and a locking mechanism 10 according to any of the above schemes, wherein the locking mechanism 10 is mounted on the battery 20 .

[0204] 2 and 3 , the battery 20 may include a box body 21 and a battery cell 22 . The battery cell 22 is used to be accommodated in the box body 21 , and the locking mechanism 10 is mounted on the box body 21 .

[0205] Optionally, the locking mechanism 10 may be mounted on the battery 20 in various structures. For example, the locking mechanism 10 may be connected to the battery 20 by bolting, bonding, welding, or clamping.

[0206] In this embodiment, by installing the locking mechanism 10 on the battery 20, the battery 20 can be locked or unlocked with the lock seat 300 of the target part through the locking mechanism 10, so as to realize the battery replacement function of the battery 20.

[0207] According to some embodiments of the present application, the present application also provides an electrical device, as shown in Figures 2 and 10, the electrical device includes a lock seat 300 and a battery assembly 100 of any of the above schemes, the locking mechanism 10 is used to engage or disengage with the lock seat 300 along the first direction X, and the battery 20 of the battery assembly 100 is used to provide electrical energy to the electrical device.

[0208] The power-consuming device may be any of the aforementioned devices or systems using the battery 20 .

[0209] For the convenience of explanation, the following embodiments are described by taking a vehicle 1000 as an example of an electrical device according to an embodiment of the present application, with reference to FIG1 and FIG2 .

[0210] Vehicle 1000 includes a mounting frame 200, and a lock base 300 is mounted on the mounting frame 200. Optionally, the lock base 300 and the mounting frame 200 may be integral or separate structures. When the lock base 300 and the mounting frame 200 are integral, that is, the lock base 300 is part of the mounting frame 200; 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 welding, bolting, or clamping. For example, in FIG2 , the lock base 300 and the mounting frame 200 are separate structures, and the lock base 300 is bolted to the mounting frame 200.

[0211] The battery assembly 100 includes a locking mechanism 10 and a battery 20 . The locking mechanism 10 is mounted on the battery 20 . The locking mechanism 10 is used to lock or unlock with the lock seat 300 to achieve battery replacement of the vehicle 1000 .

[0212] In some embodiments, as shown in FIG10 , a lock hole 310 is provided on the lock base 300 for inserting the locking member 12. The lock hole 310 passes through both sides of the lock base 300 along the first direction X. After the locking member 12 is inserted into the lock hole 310, the adjusting member 13 is rotated to drive the clamping portion 122 of the locking member 12 to rotate around the axis extending along the first direction X, so that the clamping portion 122 can be engaged with the surface of the lock base 300 on the side away from the sleeve 11, so that the locking mechanism 10 and the lock are locked. The seat 300 engages in the first direction X, thereby realizing mutual locking between the locking mechanism 10 and the lock seat 300. Conversely, when the adjusting member 13 is rotated and the clamping portion 122 of the locking member 12 is driven to rotate until the projection of the clamping portion 122 in the first direction X is located in the lock hole 310, the locking member 12 can be withdrawn from the lock hole 310, so that the locking mechanism 10 and the lock seat 300 can be disengaged in the first direction X, thereby realizing mutual unlocking between the locking mechanism 10 and the lock seat 300.

[0213] Among them, the cross-section of the locking hole 310 is rectangular. When the extension direction of the clamping portion 122 is consistent with the length direction of the cross-section of the locking hole 310, the clamping portion 122 can be inserted into the locking hole 310 or can be withdrawn from the locking hole 310. When the clamping portion 122 passes through the locking hole 310 and the extension direction of the clamping portion 122 intersects with the length direction of the cross-section of the locking hole 310, the clamping portion 122 can be engaged with the surface of the lock seat 300 on the side facing away from the sleeve 11.

[0214] According to some embodiments of the present application, the present application further provides a locking device, which includes a lock seat 300 and a locking mechanism 10 of any of the above schemes, and the locking mechanism 10 is used to engage or disengage with the lock seat 300 along the first direction X.

[0215] According to some embodiments of the present application, as shown in Figures 4 to 14, the present application provides a locking mechanism 10 for engaging with or disengaging from a lock base 300 along a first direction X. The locking mechanism 10 includes a sleeve 11, a locking member 12, an adjusting member 13, and an anti-loosening assembly 15.
