[0066] In the first aspect, the present application provides a locking mechanism 100 for a battery 200, comprising a base 10, a locking assembly 20 and an anti-rotation assembly 30; the locking assembly 20 comprises a first locking member 21 and a second locking member 22, the first locking member 21 being movably arranged on the base 10 along its own axial direction X, the second locking member 22 being connected to one end of the first locking member 21 along the axial direction X, the second locking member 22 being configured to lock the first locking member 21 to a target component or release the lock of the first locking member 21 from the target component by rotation; the anti-rotation assembly 30 is used to connect with the second locking member 22 and the base 10 and limit the rotation of the second locking member 22 relative to the base 10, wherein in the radial direction of the first locking member 21, the positive projection of the anti-rotation assembly 30 and the first locking member 21 can at least partially overlap.

[0067] The locking mechanism 100 can be applied to a battery, and further applied to detachably connect the battery with other external components. The locking mechanism 100 includes a base 10 for providing support and bearing, a locking assembly 20 for achieving compression locking, and an anti-rotation assembly 30 for maintaining the locked state after locking.

[0068] Optionally, the base 10 may be cylindrical and at least partially surround the locking assembly 20 and the anti-rotation assembly 30, so as to facilitate the locking assembly 20 to move along its own axial direction X. The base 10 may have an accommodating cavity, and through holes are respectively provided on two opposite sides of the accommodating cavity along the axial direction X, the first locking member 21 may extend from one of the through holes, and the second locking member 22 may be at least partially exposed to the outside through the other through hole.

[0069] Optionally, the outer surface of the base 10 can be cylindrical or nearly cylindrical to facilitate installation. The base 10 can be an integrally formed structure or assembled from a plurality of independently formed parts. The base 10 can be made of metal or other high-strength materials. For example, the base 10 can be made of steel, aluminum alloy or other materials.

[0070] Optionally, the locking assembly 20 includes a first locking member 21 and a second locking member 22, wherein at least the first locking member 21 is capable of moving relative to the base 10 along the axial direction X, and the second locking member 22 can be optionally kept fixed in relative position with the base 10 in this direction, so as to facilitate the relative movement between the first locking member 21 and the base 10 through the relative movement between the first and second locking members.

[0071] Optionally, moving the first locking member 21 toward the base 10 can clamp the component to be connected between the first locking member 21 and the base 10, thereby achieving a state of being locked to the target component; moving the first locking member 21 away from the base 10 can release the lock from the target component.

[0072] Optionally, the second locking member 22 and the first locking member 21 may be connected by a threaded connection, a rack and pinion connection, or the like, so that the second locking member 22 can adjust the relative position of the first locking member 21 and the base 10 in the axial direction X by rotating itself.

[0073] Optionally, the anti-rotation assembly 30 is disposed between the second locking member 22 and the base 10, and can fix the relative position of the second locking member 22 to the base 10 in the circumferential direction, that is, lock the second locking member 22 so that it cannot rotate, thereby fixing the position of the first locking member 21 in the axial direction X, that is, the first locking member 21 can stably stay in the locked state or the unlocked state. The anti-rotation assembly 30 can be optionally disposed at least partially around the second locking member 22.

[0074] The first locking member 21 in the locking mechanism 100 can move relative to the base 10 along the axial direction X. In the locked state, the overlapping length of the first locking member 21 and the base 10 is greater than the overlapping length of the two in the unlocked state. Optionally, at least in the locked state, the distribution area of ​​the first locking member 21 in the axial direction X overlaps with the distribution area of ​​the anti-rotation assembly 30 in the axial direction X. Optionally, there is still an overlapping area in the unlocked state.

[0075] The anti-rotation component 30 in the present application is arranged on a side of the locking component 20 close to the second locking member 22, and the overlapping area between the first locking member 21 and the second locking member 22 in the axial direction X is adjustable. By making the first locking member 21 have a distribution area overlapping with the anti-rotation component 30 in the axial direction X, that is, the first locking member 21 and the anti-rotation component 30 at least partially share the space in the axial direction X, the overall structural compactness of the locking mechanism 100 can be effectively improved, and the space required for setting the locking mechanism 100 can be reduced, making it easy to load and unload.

[0076] In some optional embodiments, the anti-rotation assembly 30 includes an anti-rotation member 31, an elastic member 32 and a stopper 33. The anti-rotation member 31 is sleeved on the second locking member 22 and movably connected to the second locking member 22 along the axial direction X. The elastic member 32 is clamped between the second locking member 22 and the anti-rotation member 31 or between the base 10 and the anti-rotation member 31 in the axial direction X. The stopper 33 is fixed to the base 10 and is located on the side of the anti-rotation member 31 away from the elastic member 32. The stopper 33 is used to cooperate with the anti-rotation member 31 and limit the rotation of the second locking member 22 through the anti-rotation member 31. In the radial direction of the first locking member 21, the orthographic projections of the elastic member 32 and the first locking member 21 at least partially overlap.

[0077] Specifically, the anti-rotation assembly 30 may include an anti-rotation member 31 connected to the second locking member 22 and capable of synchronously rotating in the circumferential direction, a stop member 33 connected to the base 10 and synchronously stationary in the circumferential direction, and an elastic member 32 for pressing the anti-rotation member 31 against the stop member 33.

[0078] Optionally, the anti-rotation member 31 can be sleeved on the second locking member 22, the second locking member 22 can be set to a polygonal shape, and the anti-rotation member 31 has a through hole of a corresponding shape, so that the two can rotate synchronously. Alternatively, one of the second locking member 22 and the anti-rotation member 31 can be provided with a protruding portion protruding in the radial direction, and the other can be provided with a concave portion recessed in the radial direction, so that the protruding portion at least partially extends into the concave portion, so that the two can rotate synchronously.

[0079] Optionally, the stopper 33 is connected to the inner side of the base 10 and keeps synchronization with the base 10 in the circumferential direction. When any component in the locking assembly 20 rotates, the stopper 33 and the base 10 can keep synchronous and stationary. Similar to the setting of the anti-rotation member 31, the stopper 33 can achieve synchronization in the circumferential direction by setting a protrusion / recess or setting it in a polygonal structure. Alternatively, the stopper 33 can be fixedly connected to the base 10 to achieve synchronization.

[0080] Optionally, the elastic member 32 is arranged on the side of the anti-rotation member 31 away from the stop member 33, and is used to press the anti-rotation member 31 against the stop member 33 in the axial direction X. The elastic member 32 extends as a whole along the axial direction X and can be compressed or expanded in this direction. One end of the elastic member 32 abuts against the surface of the side of the anti-rotation member 31 away from the stop member 33, and the other end opposite can abut against the base 10 or the second locking member 22, so that it can exert a force along the axial direction X on the anti-rotation member 31 through its own compression, so that the anti-rotation member 31 and the stop member 33 are coupled to each other, and through this coupling relationship, the second locking member 22 is synchronized with the base 10 in the circumferential direction and is stationary, preventing the second locking member 22 from rotating.

[0081] Optionally, the elastic member 32 may be a spring and is sleeved on the second locking member 22 .

[0082] In the anti-rotation assembly 30 , the elastic member 32 needs to be compressed and stretched in the axial direction X and thus requires a larger space. Therefore, the elastic member 32 shares the axial space with the first locking member 21 in the axial direction X, which can further reduce the space required for the locking mechanism 100 as a whole.

[0083] In some optional embodiments, the anti-rotation component 31 is configured to switch the anti-rotation component 31 and the stopper 33 between a disengaged state and a locked state by moving in the axial direction X.

[0084] Optionally, the anti-rotation member 31 can abut against the stop member 33 in the axial direction X and cooperate with each other to limit the second locking member 22 in the circumferential direction. After the anti-rotation member 31 moves along the axial direction X and disengages from the stop member 33, the coupling between the two can be invalidated, and the stop member 33 no longer restricts the rotation of the anti-rotation member 31.

[0085] Optionally, one of the anti-rotation member 31 and the stop member 33 may be provided with a protrusion, and the other may be provided with a recessed portion, the protrusion being inserted into the recessed portion so that the anti-rotation member 31 and the stop member 33 are synchronized in the circumferential direction, and one or more protrusions and recessed portions may be provided, and the two may be provided in a one-to-one correspondence. Optionally, the protrusion may extend along the axial direction X, or the protrusion may extend in a direction having a certain angle with the axial direction X, so that the abutment surface between the anti-rotation member 31 and the stop member 33 extends in an oblique direction.

[0086] For example, when the locking mechanism 100 is used and unlocking is required, the external unlocking and locking mechanism 600 can be used to first push the anti-rotation member 31 along the axial direction X so that the anti-rotation member 31 is separated from the stop member 33, and the stop member 33 no longer restricts the rotation of the anti-rotation member 31 and the second locking member 22. Then, the unlocking and locking mechanism 600 can drive the second locking member 22 to rotate so that the first locking member 21 moves away from the second locking member 22 and disengages from the target component, thereby releasing the lock between the locking mechanism 100 and the target component. After unlocking is completed, the unlocking and locking mechanism 600 can move along the axial direction X in a direction away from the anti-rotation member 31, so that the anti-rotation member 31 resumes coupling with the stop member 33, and the unlocking and locking mechanism 600 is separated from the anti-rotation member 31 and the second locking member 22.

[0087] Correspondingly, when locking is required, the anti-rotation member 31 is also first pushed to separate the anti-rotation member 31 from the stop member 33, and then the second locking member 22 is driven to rotate in the opposite direction, so that the first locking member 21 moves toward the second locking member 22 and presses the target component between the first locking member 21 and the base 10, thereby completing the locking. Finally, the unlocking mechanism 600 is disengaged along the axial direction X, so that the anti-rotation member 31 resumes the coupling with the stop member 33, so that the stop member 33 again restricts the rotation of the anti-rotation member 31 and the second locking member 22.

[0088] The anti-rotation assembly 30 provided with the elastic member 32 can conveniently adjust the locking state of the second locking member 22 by abutting or separating the anti-rotation member 31 and the stop member 33, so that the locking and unlocking of the locking mechanism 100 is convenient and fast.

[0089] Optionally, when the elastic member 32 is provided, one end of the elastic member 32 can be abutted against the rotating anti-rotation member 31, and the other end can be abutted against the synchronously rotating second locking member 22, so that the two ends of the elastic member 32 can rotate synchronously to avoid being damaged by the torsional force during the locking and unlocking process. Similarly, one end of the elastic member 32 can be abutted against the non-rotating base 10, and the other end can be abutted against the non-rotating tray, gasket or other supporting member, so that both ends of the elastic member 32 do not rotate. In this way, the friction between the two ends of the elastic member 32 and the abutting surface can be reduced, and the possibility of the elastic member 32 being twisted can be reduced, thereby extending the service life and improving the overall reliability of the anti-rotation assembly 30.

[0090] In some optional embodiments, the anti-rotation member 31 and the stop member 33 are respectively provided with meshing teeth on one side close to each other, and in the locked state, the anti-rotation member 31 and the stop member 33 are meshed with each other.

[0091] On the basis that the anti-rotation member 31 and the stop member 33 are coupled to each other, both of them may be provided with meshing teeth, and the meshing teeth respectively provided on the two members can mesh with each other and realize connection and fixation in the circumferential direction.

[0092] Optionally, the meshing surface between the anti-rotation component 31 and the stopper 33 may be a plane perpendicular to the axial direction X, or the meshing surface may be a funnel-shaped curved surface having a certain angle with the axial direction X.

[0093] Arranging the anti-rotation member 31 and the stop member 33 to be connected through tooth engagement can make the locking between the anti-rotation member 31 and the stop member 33 stable and reliable, and after the anti-rotation member 31 rotates with the second locking member 22, the anti-rotation member 31 can still smoothly engage and position with the stop member 33, eliminating the step of finding the corresponding position for docking, thereby improving the reliability of the locking mechanism 100.

[0094] Please also read Figures 5 and 6 , Figure 5 A partial structural diagram of a second locking member provided in some embodiments of the present application, Figure 6 for Figure 5 In some optional embodiments, the second locking member 22 is provided with a connecting hole 221 extending along the axial direction X, a portion of the first locking member 21 extends into the connecting hole 221 and is threadedly connected to the second locking member 22; in the radial direction, the orthographic projection of the connecting hole 221 at least partially overlaps with the orthographic projection of the elastic member 32.

[0095] Optionally, the second locking member 22 has a connection hole 221 that is recessed on one side away from the first locking member 21 along the axial direction X, and the connection hole 221 may be provided with an internal thread. One end of the first locking member 21 extends into the connection hole 221, and a portion of the first locking member 21 near the end is provided with an external thread, so that the first locking member 21 and the second locking member 22 are threadedly connected to each other.

[0096] In the embodiment in which the first and second locking members are threadedly connected, the first locking member 21 can be limited circumferentially. At this time, rotating the second locking member 22 can conveniently achieve relative movement between the first locking member 21 and the second locking member 22, so that the locking mechanism 100 can conveniently switch between the locked and unlocked states.

[0097] In some optional embodiments, the second locking member 22 includes a first part 222 and a second part 223 arranged along the axial direction X, and in the radial direction of the connecting hole 221, the first part 222 protrudes from the second part 223; the connecting hole 221 starts from the surface of the first part 222 away from the second part 223; in the axial direction X, the elastic member 32 is clamped between the first part 222 and the anti-rotation member 31.

[0098] Optionally, sections of the second locking member 22 located at different positions on the axial direction X may have a certain diameter difference, so that the second locking member 22 forms a first part 222 with a larger diameter and a second part 223 with a smaller diameter, and the two are connected by an annular surface from the first part 222 to the second part 223, and the extension direction of the annular surface intersects the axial direction X, and can be optionally perpendicular to each other.

[0099] Optionally, the central axes of the first portion 222 and the second portion 223 coincide with each other, so that the second locking member 22 can rotate stably.

[0100] Optionally, the first portion 222 may be a segment extending along the axial direction X, or the first portion 222 may be a flange protruding in the radial direction.

[0101] Optionally, one end of the elastic member 32 abuts against the aforementioned annular surface, and the other end abuts against the anti-rotation member 31, and the anti-rotation member 31 is pressed against the stop member 33 by the support of the second locking member 22. The abutment of the elastic member 32 with the second locking member 22 facilitates the application of an axial force X to the elastic member 32.

[0102] Optionally, the difference in diameter between the first portion 222 and the second portion 223 is greater than the width of the elastic member 32 in the radial direction, so as to stabilize the abutment.

[0103] Please also read Figure 7 and Figure 8 , Figure 7A partial structural diagram of a second locking member provided in some other embodiments of the present application, Figure 8 for Figure 7 In some optional embodiments, a first groove 224 is provided on the surface of the first portion 222 facing the second portion 223 , and at least a portion of the elastic member 32 is accommodated in the first groove 224 and abuts against the bottom surface of the first groove 224 .

[0104] Optionally, the surface of the first part 222 facing the second part 223 abuts against the elastic member 32, and the side surface may be provided with a first groove 224. The opening of the first groove 224 is located at the aforementioned connecting surface, and is recessed along the axial direction X, and its width may be slightly larger than the width of the elastic member 32 in the radial direction.

[0105] Optionally, the inner wall of the first groove 224 close to the central axis of the second locking member 22 can abut against the inner wall of the elastic member 32, so that the elastic member 32 is partially sleeved on the annular inner wall of the first groove 224 to provide a good limiting effect in the radial direction.

[0106] Optionally, the depth of the first groove 224 is set according to the extension dimension of the elastic member 32 in the axial direction X, so that the elastic member 32 can be in a compressed state when the anti-rotation member 31 abuts the stop member 33, and the size of the elastic member 32 after being fully compressed is greater than the depth of the first groove 224.

[0107] Optionally, the central axis of the first groove 224 may coincide with the central axes of the first portion 222 and the second portion 223 .

[0108] Providing the first groove 224 on the abutting surface can further bring the first locking member 21 and the elastic member 32 closer to each other, thereby further reducing the size required for the entire locking mechanism 100 in the axial direction X. At the same time, by limiting the position of the elastic member 32 by the first groove 224, the possibility of radial displacement of the elastic member 32 can be reduced, thereby improving the reliability of the locking mechanism 100.

[0109] In some optional embodiments, a portion of the connecting hole 221 extends to the second portion 223 , and the elastic member 32 is sleeved on the second portion 223 .

[0110] Optionally, the connecting hole 221 starts from a side of the first portion 222 away from the second portion 223 and extends into the second portion 223 in a direction close to the second portion 223 , so that the elastic member 32 is sleeved on the second portion 223 and shares the space on the axial direction X with the connecting hole 221 .

[0111] Optionally, in the second part 223, the diameter of the partial section where the connecting hole 221 is provided may be larger than the diameter of the partial section offset from the connecting hole 221, that is, the partial section where the connecting hole 221 is located after extending into the second part 223 is thickened so that it still has good structural strength after the connecting hole 221 is provided inside.

[0112] By sinking the connecting hole 221 and partially setting it in the second part 223, the maximum overlap size of the first locking member 21 and the second locking member 22 in the axial direction X can be increased, thereby further improving the structural compactness of the locking mechanism 100. At the same time, the space occupied after locking to the target component can be reduced, thereby improving the applicability of the locking mechanism 100.

[0113] See also Fig. 9 , Fig. 9 for Figure 3 Another cross-sectional view at A-A' is shown. In some optional embodiments, the base 10 encloses a housing cavity 11, and the housing cavity 11 includes a first cavity 111 and a second cavity 112 arranged along the axial direction X and interconnected, and the diameter of the first cavity 111 is smaller than the diameter of the second cavity 112; the anti-rotation component 30 is disposed in the second cavity 112, and one end of the elastic member 32 abuts against the connecting surface between the first cavity 111 and the second cavity 112, and the other end abuts against the anti-rotation member 31.

[0116] Optionally, the accommodating cavity 11 includes a first cavity 111 and a second cavity 112, which are interconnected and have different diameters. Thus, the side walls enclosing the accommodating cavity 11 form a connecting surface at the connection between the two cavities, the extension direction of which intersects the axial direction X. The connecting surface can be annular and constitute a partial wall surface of the second cavity 112 with a larger diameter.

[0117] Optionally, the anti-rotation assembly 30 is disposed in the second cavity 112 with a larger diameter so that it has sufficient rotation space. The elastic member 32 in the anti-rotation assembly 30 abuts against the aforementioned connection surface and is supported in the axial direction X through the connection surface.

[0118] Optionally, the width of the connecting surface in the radial direction is greater than the dimension of the elastic member 32 in the radial direction.

[0119] The elastic member 32 may also abut against the wall of the inner cavity of the base 10 , and the structure of the anti-rotation assembly 30 can be further stabilized by the base 10 supporting the elastic member 32 .

[0120] In some optional embodiments, the connecting surface is provided with a second groove 113 , and at least a portion of the elastic member 32 is accommodated in the second groove 113 and abuts against a bottom surface of the second groove 113 .

[0121] Similar to the first groove 224 provided on the second locking member 22, in the embodiment where the elastic member 32 abuts against the base 10, a second groove 113 can also be provided on the base 10, and the opening of the second groove 113 is provided on the aforementioned connecting surface at the boundary between the first cavity 111 and the second cavity 112, and the second groove 113 is recessed along the axial direction X away from the anti-rotation member 31.

[0122] Optionally, the width and radial position of the second groove 113 are arranged in a manner similar to those of the first groove 224 , and will not be described in detail in this application.

[0123] By arranging the second groove 113 on the base 10 and partially extending the elastic member into the second groove 113 , the required size of the locking mechanism 100 in the axial direction X can be further reduced.

[0124] In some optional embodiments, the anti-rotation component 31 includes an anti-rotation body 311 and an anti-rotation flange 312 surrounding the anti-rotation body 311, the anti-rotation body 311 is sleeved on the second locking component 22, and the anti-rotation body 311 passes through the stop member 33 along the axial direction X; the anti-rotation flange 312 is opposite to the elastic component 32 on one side along the axial direction X, and is used to cooperate with the stop member 33 on the other side along the axial direction X.

[0125] Optionally, the anti-rotation member 31 may be composed of a cylindrical anti-rotation body 311 and an anti-rotation flange 312 protruding from the outer circumference of the anti-rotation body 311. The anti-rotation body 311 is sleeved on the second locking member 22, and its shape can match the shape of the outer circumference of the second locking member 22 so that the two can rotate synchronously.

[0126] Optionally, the stopper 33 is connected to the base 10 and is arranged around the second locking member 22. Its inner diameter can be slightly larger than the diameter of the outer peripheral surface of the anti-rotation body 311, so that the anti-rotation body 311 can pass through the stopper 33 and move relative to the stopper 33 along the axial direction X.

[0127] Optionally, on the two opposite sides of the anti-rotation flange 312 in the axial direction X, the side facing the stop member 33 may be provided with a structure required for coupling with the stop member 33, such as meshing teeth, etc.; and the side facing the elastic member 32 may abut against the elastic member 32 to apply a supporting force along the axial direction X to the elastic member 32.

[0128] Optionally, the interface between the anti-rotation flange 312 and the stopper 33 that cooperates with each other may be perpendicular to the axial direction X, or the interface may be arranged at an angle.

[0129] Providing the anti-rotation member 31 with the anti-rotation flange 312 makes it easy to stably contact the elastic member 32 against the anti-rotation member 31 when the anti-rotation member 31 is connected to the second locking member 22 .

[0130] In some optional embodiments, a third groove is provided on the side of the anti-rotation flange 312 facing the elastic member 32 , and at least a portion of the elastic member 32 is accommodated in the third groove and abuts against the bottom surface of the third groove.

[0131] Similar to the first groove 224 and the second groove 113, a third groove can be correspondingly arranged on the anti-rotation flange 312. The third groove starts from the side of the anti-rotation flange 312 toward the elastic member 32 and is recessed along the axial direction X. It is used to limit the end of the elastic member 32 that abuts the anti-rotation member 31 and compress the space on the axial direction X.

[0132] Optionally, in an embodiment where the first groove 224 and the third groove are provided at the same time, the first groove 224 and the third groove are provided opposite to each other in the axial direction X; in an embodiment where the second groove 113 and the third groove are provided at the same time, the second groove 113 and the third groove are provided opposite to each other in the axial direction X.

[0133] Optionally, the first groove 224 , the second groove 113 and the third groove may all have the same width, diameter and depth; or, the depth of the third groove may be made shallower to reduce the thickness required for the anti-rotation flange 312 .

[0134] By providing the third groove on the anti-rotation flange 312 , the size of the locking mechanism 100 in the axial direction X can be further reduced, while reducing the radial displacement range of the elastic member 32 , thereby reducing wear and improving reliability.

[0136] The locking mechanism 100 may also be provided with a limit assembly for limiting the rotation angle of the first locking member 21. Optionally, the limit assembly may be arranged on the target component to be connected, or the limit assembly may be an independently arranged clamping structure, such as a blocking structure abutting against the first locking member 21 at a preset angle, or the limit assembly may be arranged in the locking mechanism 100.

[0137] Optionally, the aforementioned limiting structure can be disposed in the locking mechanism 100 to make it easier to process and use and convenient to assemble and disassemble. Specifically, the locking mechanism 100 can also include a limiting pin 40 and a limiting groove 50, one of which is disposed on the base 10 and the other is disposed on the first locking member 21, for guiding the relative position change between the first locking member 21 and the base 10 by mutual cooperation.

[0138] Specifically, the locking mechanism 100 may be provided with a plurality of limit pins 40 and limit slots 50 at the same time, and the two may be provided in one-to-one correspondence and centrally symmetrically with respect to the central axis of the first locking member 21 so that the guiding force is uniform.

[0139] Optionally, the limit pin 40 can be set on the base 10 or the first locking member 21, and can be connected in a detachable manner, that is, a hole is provided in the base 10 or the first locking member 21, and the limit pin 40 is set in the hole to facilitate processing and connection.

[0140] Optionally, the specific rotation range of the first locking member 21 in the circumferential direction can be adjusted accordingly by adjusting the angle over which the limiting groove 50 extends in the circumferential direction.

[0141] Specifically, the first locking member 21 and the second locking member 22 can be optionally threadedly connected. By limiting the rotation angle of the first locking member 21, it can be limited and kept in a fixed position in the circumferential direction after rotating through a preset angle. The second locking member 22 can be rotated and the first and second locking members can be moved toward or away from each other in the axial direction X through the thread therebetween, thereby achieving locking and unlocking of the target component.

[0142] The cooperation of the limiting pin 40 and the limiting groove 50 can fix the movable range of the first locking member 21 in the circumferential direction, and can conveniently and reliably cause the first locking member 21 and the second locking member 22 to have relative displacement through structures such as threads.

[0146] Optionally, the second sub-groove 52 extends along the axial direction X, and can prevent the first locking member 21 from rotating and move in the axial direction X, so as to lock or unlock the target component.

[0147] Optionally, the first sub-groove 51 and the second sub-groove 52 may have the same width and depth, and may be interconnected and extend smoothly.

In a cross section perpendicular to the axial direction X, the interface figure formed by the press head 212 can be rectangular, triangular, Y-shaped, elliptical, etc., so that after the press head 212 passes through the hole on the target component, it can be pressed against the surface of the target component by rotating the press head 212 to a certain angle.

[0153] Optionally, when setting the components such as the limit groove and the limit pin for limiting the rotation angle of the first locking member 21, the design can be made according to the shape of the pressure head 212. For example, the cross section of the pressure head 212 is rectangular, so it can be rotated 90°, and the cross section of the pressure head 212 is an equilateral triangle, so it can be rotated 60°. By setting the rotation angle accordingly, the pressing area between the pressure head 212 and the external component can be increased, making the connection more stable.

[0154] Optionally, the pressing head 212 may be in the form of a cuboid to facilitate processing, and the cuboid can have a larger pressing area after being rotated 90°.

[0163] Optionally, the base 10 is passed through the mounting hole 64, and is detachably connected to the box body 60 through flanges or bolt holes, pin controls and other structures on the base 10, so that the locking mechanism 100 is connected and fixed to the box body 60, which facilitates the connection between the battery 200 and the external target component by clamping the external target component between the first locking member 21 and the base 10.

[0164] In the third aspect, according to an embodiment of the present application, a vehicle 1000 is provided, comprising a vehicle body and a battery 200 in any embodiment of the second aspect, the vehicle body comprising a fixing member 500, the battery 200 being located on the lower side of the vehicle body, the first locking member 21 being locked to the fixing member 500, and the battery 200 being used to provide electrical energy.

[0165] Optionally, the battery 200 may be applied to the vehicle 1000 and used to provide electrical energy for the vehicle 1000 , and the vehicle body includes a fixing member 500 , which may be a supporting beam of the vehicle body.

[0166] The battery 200 is detachably connected to the fixing member 500 via the locking mechanism 100, and at least a portion of the structure of the fixing member 500 is clamped between the first locking member 21 and the base 10. Optionally, a portion of the structure of the box body 60 may be abutted against the fixing member 500 and clamped between the first locking member 21 and the base 10 to ensure a stable connection.

[0167] The locking mechanism 100 is provided for connection, so that the space required for connection can be reduced, and the first locking member 21 can be inserted into a closed cavity having only a connection hole for connection, which has good applicability.

[0168] See also Fig.11 , Fig.11 for Figure 3Another cross-sectional view at A-A' is shown. In some optional embodiments, the first locking member 21 includes a locking rod 211 and a pressing head 212, the pressing head 212 is connected to one end of the locking rod 211 along the axial direction X and is located outside the base 10; the fixing member 500 is provided with a fixing hole 80, and the pressing head 212 is configured to be able to pass through the fixing hole 80; in the first direction Y, the size of the pressing head 212 is larger than the size of the fixing hole 80; in the second direction Z, the size of the pressing head 212 is smaller than the size of the fixing hole 80, and the first direction Y, the second direction Z and the axial direction X are perpendicular to each other; in the axial direction X, a part of the fixing member 500 is clamped between the pressing head 212 and the base 10.

[0169] As mentioned above, the first locking member 21 may include a rod-shaped locking rod 211 extending along the axial direction X and a pressing head 212 connected to the locking rod 211 and protruding from the locking rod 211 in the radial direction.

[0170] When the locking mechanism 100 is connected to the fixing member 500, the angle of the pressing head 212 is adjusted so that the pressing head 212 and part of the locking rod 211 can pass through the fixing hole 80 of the fixing member 500. When locking, the first locking member 21 is rotated by a certain angle. After the rotation, its positive projection on the axial direction X can overlap with part of the area around the fixing hole 80.

[0171] Specifically, in the locked state, in the first direction Y, the size of the pressing head 212 can be made larger than the size of the fixing hole 80, and in the second direction Z, the size of the pressing head 212 can be made smaller than the fixing hole 80, so that the pressing head 212 can pass through the fixing hole 80 and can be rotated to have a certain size of clamping area between the pressing head 212 and the fixing member 500.

[0172] Taking the example that the pressing head 212 is a rectangular parallelepiped and the fixing hole 80 is a rectangular hole, the length of the pressing head 212 should be smaller than the length of the fixing hole 80, and the width of the pressing head 212 should be smaller than the width of the fixing hole 80, so that the pressing head 212 can pass through the fixing hole 80. At the same time, after rotating and locking, the pressing head 212 can be rotated 90°, and the length of the pressing head 212 can be greater than the width of the fixing hole 80, so that the two ends of the pressing head 212 can be pressed tightly on the fixing member 500.

[0176] Subsequently, the unlocking mechanism 600 rotates the second locking member 22, and the first locking member 21 is driven to move by the rotation of the second locking member 22. The first locking member 21 can be optionally raised linearly first and then spirally raised, thereby releasing the lock between the first locking member 21 and the fixing member 500.

[0180] Then, the battery exchange equipment descends, and the unlocking mechanism 600 disengages from the second locking member 22 and the anti-rotation member 31. The anti-rotation member 31 engages with the stop member 33 under the elastic force of the elastic member 32, thereby realizing the anti-rotation locking of the locking mechanism 100.

[0187] IV) The vehicle 1000 leaves the supporting platform.

[0188] Optionally, a stacker is provided in the battery compartment, and the stacker is used to transfer the batteries 200 to be charged that are removed from the battery swapping device to the charging position of the battery compartment for charging, and to place the fully charged batteries 200 stored in the battery compartment on the battery swapping device.
