[0059] Next, combine with Figure 3 To Attachment Fig. 9 The structure of the locking mechanism 100 will be described.

[0060] Please also read Figures 3 to 5 , Figure 3 This is a schematic diagram of the structure of the locking mechanism provided in some embodiments of the present application. Figure 4 for Figure 3 A cross-sectional view at AA' is shown, Figure 5 for Figure 4 An enlarged view of the area P is shown.

[0061] In the first aspect, the present application provides a locking mechanism 100, including a base 10, a locking assembly 20 and an anti-rotation assembly 30, wherein the locking assembly 20 includes a first locking member 21 and a second locking member 22, wherein the first locking member 21 is movably arranged on the base 10 along its own axial direction X, and the second locking member 22 is connected to one end of the first locking member 21 along the axial direction X, and the second locking member 22 is configured to lock the first locking member 21 to a target component or release the lock between the first locking member 21 and the target component by rotating; the anti-rotation assembly 30 includes the anti-rotation member 31 , an elastic member 32 and a stop member 33, the anti-rotation member 31 is sleeved on the second locking member 22 and is movably connected to the second locking member 22 along the axial direction X, the anti-rotation member 31 and the second locking member 22 are relatively fixed in the circumferential direction of the second locking member 22, the stop member 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 stop member 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; wherein, in the axial direction X, the elastic member 32 is clamped between the second locking member 22 and the anti-rotation member 31.

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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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 synchronously stationary in the circumferential direction. 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.

[0072] Optionally, the elastic member 32 is disposed 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 oppositely abuts against 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, thereby preventing the second locking member 22 from rotating.

[0073] Optionally, the second locking member 22 may be provided with a corresponding abutment surface for abutting against the elastic member 32, and the abutment surface may be provided in a direction extending to intersect the axial direction X. The abutment surface may be provided in a flange structure, a boss structure or a groove structure, etc., so as to abut against the elastic member 32 in a aligned manner and apply a force along the axial direction X.

[0074] Optionally, the elastic member 32 may be a spring and is sleeved on the second locking member 22 .

[0075] In the technical solution of the embodiment of the present application, when the locking assembly 20 realizes the switching between the locked state and the unlocked state by rotating, the anti-rotation member 31 will rotate synchronously with the second locking member 22 in the locking assembly 20. The elastic member 32 is arranged to be in contact with the second locking member 22 and the anti-rotation member 31 at both ends, respectively, so that the elastic member 32 and the anti-rotation member 31 can rotate synchronously in the circumferential direction during the rotation of the anti-rotation member 31, thereby reducing the speed difference between the two ends of the elastic member 32, reducing the risk of torsional failure of the elastic member 32 and the risk of wear of the elastic member 32, and improving the stability and reliability of the locking mechanism 100.

[0076] In some optional embodiments, the second locking member 22 includes a locking body 222 and a limiting flange 223, the locking body 222 is connected to the first locking member 21, and the limiting flange 223 surrounds the locking body 222; the elastic member 32 is sleeved on the locking body 222, and in the axial direction X, the elastic member 32 is clamped between the limiting flange 223 and the anti-rotation member 31.

[0077] Optionally, the second locking member 22 may include a locking body 222 and a limiting flange 223, wherein the locking body 222 may be a columnar structure extending along the axial direction X, and may be connected to the first locking member 21 by providing a connecting hole or other structural forms. The first locking member 21 is connected to one end of the locking body 222 in the axial direction X.

[0078] Optionally, the limiting flange 223 is provided to protrude radially from the outer peripheral surface of the locking body 222, and the extending direction of the limiting flange 223 may be selected to be perpendicular to the axial direction X. In the axial direction X, the limiting flange 223 may be provided close to one end of the locking body 222 connected to the first locking member 21, so that the elastic member 32 has sufficient accommodation space.

[0079] Optionally, the limiting flange 223 completely extends along the circumferential direction and is disposed around the locking body 222 , and the elastic member 32 is sleeved on the locking body 222 and abuts against a side surface of the limiting flange 223 facing the anti-rotation member 31 .

[0080] The second locking member 22 is configured to have a radially protruding limiting flange 223, which can facilitate the end of the elastic member 32 in the axial direction X to abut against the elastic member 32 when the elastic member 32 is sleeved on the locking body 222, so that one end of the elastic member 32 is subjected to uniform and stable force.

[0081] In some optional embodiments, the limiting flange 223 is respectively in contact with the base 10 and the elastic member 32 on two opposite sides in the axial direction X, and the limiting flange 223 is in sliding cooperation with the base 10 .

[0082] Optionally, the side surface of the limiting flange 223 facing away from the elastic member 32 can directly abut against the base 10, and the two can slide together. Specifically, the limiting flange 223 can be located at one end of the locking body 222 in the axial direction X, and the side surface of the limiting flange 223 facing the base 10 in the axial direction X can be set as a relatively smooth sliding friction surface, so that the second locking member 22 has a lower friction force with the base 10 when rotating. Sliding fit means that the surface of the limiting flange 223 abuts against the surface of the base 10, and can move relatively in a sliding manner during the rotation of the second locking member 22.

[0083] Optionally, during the process of unlocking or locking using the locking mechanism 100 , lubrication may be performed between the limiting flange 223 and the base 10 by means of lubricating grease or the like to further reduce friction loss therebetween.

[0084] Arranging the limiting flange 223 and the base 10 to be in a sliding fit can reduce the friction loss between the two while providing the supporting force along the axial direction X.

[0085] In some optional embodiments, the locking mechanism 100 further includes a washer 23 disposed around the first locking member 21 , and at least a portion of the washer 23 is clamped between the limiting flange 223 and the base 10 in the axial direction X.

[0086] Optionally, a washer 23 may be further provided in the locking mechanism 100 . The washer 23 is clamped between the limiting flange 223 and the base 10 , so that the base 10 and the limiting flange 223 are not in direct contact, and relative rotation is achieved through the washer 23 .

[0087] Optionally, the washer 23 may be annular and sleeved on the first locking member 21, and the width of the washer 23 is smaller than the difference between the diameter of the cavity of the base 10 at this position and the diameter of the first locking member 21. The washer 23 may be spaced apart from the first locking member 21 and the base 10 to reduce the possibility of contact with the first locking member 21 and the base 10 during the rotation of the second locking member 22, so that the washer 23 can rotate freely. Alternatively, the washer 23 may be positioned circumferentially through the base 10, so that it is synchronously stationary with the base 10 in this direction, and a sliding fit is achieved through a smooth surface.

[0088] Optionally, the washer 23 may be made of a material with good wear resistance and have at least one smooth surface intersecting with the axial direction X to reduce friction loss and friction heat.

[0089] In some optional embodiments, the gasket 23 is slidably matched with the base 10 and the limiting flange 223 respectively; or, the gasket 23 is connected to one of the base 10 and the limiting flange 223, and is slidably matched with the other.

[0090] Optionally, the gasket 23 can be independently provided with the base 10 and the limiting flange 223, so that the gasket 23 has a rotational freedom in the circumferential direction relative to the above two, so that the gasket 23 is easy to process. In this embodiment, at least one of the base 10 or the limiting flange 223 can be optionally provided with a groove corresponding to the size of the gasket 23, and the gasket 23 is partially embedded in the groove to limit the radial position of the gasket 23.

[0091] Optionally, the washer 23 can also be connected to one of the base 10 or the second locking member 22, and can be connected in one of the connection modes such as welding, clamping, and integral setting. One of the two opposite surfaces of the washer 23 in the axial direction X is connected to the base 10 or the second locking member 22, and the other is a smooth friction surface with a low surface roughness, so that it can slide with the unconnected one. In this way, the stability of the washer 23 can be improved and the possibility of dislocation of the washer 23 can be reduced.

[0092] See also Figure 6 , Figure 6 for Figure 4Another enlarged view of the area P shown. In some optional embodiments, at least one of the base 10 and the second locking member 22 is provided with a blocking structure 34, and at least a portion of the blocking structure 34 is located between the elastic member 32 and the base 10; or, at least a portion of the blocking structure 34 abuts against a side of the elastic member 32 facing away from the base 10, the central axis of the elastic member 32 coincides with the central axis of the blocking structure 34, and the elastic member 32 is spaced apart from the base 10.

[0093] Optionally, the anti-rotation member 31 and the second locking member 22 are respectively abutted against the elastic member 32, and at least one of the abutting surfaces thereof may be provided with a blocking structure 34. The blocking structure 34 can radially limit the elastic member 32 through a partial area between the elastic member 32 and the locking assembly 20 or a partial area between the elastic member 32 and the base 10, thereby reducing the possibility of radial misalignment of the elastic member 32.

[0094] Optionally, the blocking structure 34 may be a boss structure that protrudes toward the direction close to the elastic member 32 , or the blocking structure 34 may be a wall portion of a groove that accommodates at least a portion of the elastic member 32 extending therein.

[0095] Optionally, the barrier structure 34 can be partially disposed between the elastic member 32 and the base 10, that is, disposed on the outside of the elastic member 32, and can optionally adopt a boss structure, etc., to limit the distance between the elastic member 32 and the center axis of the second locking member 22 within a certain range, thereby keeping the elastic member 32 and the outer base 10 spaced apart from each other.

[0096] Alternatively, one side surface of the blocking structure 34 can be arranged around at least a portion of the locking assembly 20 and abut against the inner side wall of the elastic member 32, so that the elastic member 32 is partially sleeved on the blocking structure 34 to provide a good limiting effect in the radial direction. In this embodiment, by adjusting the diameter of the blocking structure 34, the elastic member 32 and the base 10 can also be kept spaced from each other.

[0097] Optionally, in an embodiment where the barrier structure 34 is disposed inside the elastic member 32 , the diameter of the barrier structure 34 may be the same as or slightly smaller than the inner diameter of the elastic member 32 , so as to further stabilize the position of the elastic member 32 .

[0098] The barrier structure 34 can reduce the possibility of radial displacement of the elastic member 32, thereby reducing the possibility of friction between the elastic member 32 and other components or the inability to flexibly rotate with the second locking member 22 due to contact with the base 10 and being affected by torsional force.

[0099] In some optional embodiments, the barrier structure 34 is disposed around the locking assembly 20 .

[0100] Optionally, the barrier structure 34 may be annular and completely extend in the circumferential direction of the locking assembly 20 to provide support and positioning in all radial directions, and at the same time increase the contact area between the barrier structure 34 and the elastic member 32, thereby further improving the reliability of limiting the position of the elastic member 32 in the radial direction, fixing the position of the elastic member 32, and reducing the possibility of the elastic member 32 being misplaced due to multiple compressions and stretches.

[0101] In some optional embodiments, a blocking groove 341 is provided on the side of the second locking member 22 facing the elastic member 32, and / or a blocking groove 341 is provided on the side of the anti-rotation member 31 facing the elastic member 32, and the elastic member 32 extends into the blocking groove 341; the side wall of the blocking groove 341 is a blocking structure 34.

[0102] Optionally, the blocking structure 34 can be in the form of being arranged in a blocking groove 341, that is, a blocking groove 341 is arranged on the side of the second locking member 22 or the anti-rotation member 31 facing the elastic member 32, and the end of the elastic member 32 extends into the blocking groove 341, and the inner wall or outer wall of the blocking groove 341 is used as the blocking structure 34.

[0103] Optionally, the opening of the blocking groove 341 is located on the aforementioned abutting surface and is recessed along the axial direction X, and the width thereof may be slightly greater than the width of the elastic member 32 in the radial direction.

[0104] Optionally, the depth of the blocking groove 341 is set according to the extension dimension of the elastic member 32 in the axial direction X, so that the elastic member 32 is still in a compressed state when the anti-rotation member 31 abuts against the stop member 33, and the size of the elastic member 32 after being fully compressed is greater than the depth of the blocking groove 341.

[0105] By configuring the blocking structure 34 as a side wall of the blocking groove 341 , the radial limiting can be further stabilized and reliable, thereby improving the overall reliability of the locking mechanism 100 .

[0106] In some optional embodiments, the second locking member 22 includes a locking body 222 and a limiting flange 223 , and a blocking structure 34 is respectively provided on the limiting flange 223 and a side of the anti-rotation member 31 facing the elastic member 32 .

[0107] The second locking member 22 may include a locking body 222 extending along the axial direction X and a limiting flange 223 radially protruding from the locking body 222, wherein the limiting flange 223 may be an annular plate-shaped member having two side surfaces opposite to each other in the axial direction X, wherein a side surface facing the elastic member 32 may be provided with a blocking groove 341.

[0108] Optionally, the side of the anti-rotation member 31 facing the elastic member 32 may also be provided with a blocking groove 341. In the embodiment where the anti-rotation member 31 includes an anti-rotation body and an anti-rotation flange surrounding the anti-rotation body, the blocking groove 341 may be similarly provided on the side of the anti-rotation flange facing the elastic member 32.

[0109] Providing blocking grooves 341 on the surfaces of the second locking member 22 and the anti-rotation member 31 where the extension direction intersects the axial direction X can make the limiting of the elastic member 32 more stable and reduce the possibility of the elastic member 32 detaching from the blocking structure 34 due to compression or extension.

[0110] In some optional embodiments, the blocking structures 34 respectively disposed on the limiting flange 223 and the anti-rotation component 31 have the same width and are correspondingly disposed in the axial direction X.

[0111] Optionally, in an embodiment where barrier structures 34 are provided at both ends of the elastic member 32 in the axial direction X, the barrier grooves 341 on both sides may be provided opposite to each other in the axial direction X so that the elastic member 32 is subjected to uniform force at various locations in the circumferential direction and is not easily bent or tilted.

[0112] Optionally, each barrier groove 341 may have the same width, diameter, and depth to facilitate processing.

[0113] In some optional embodiments, the anti-rotation component 31 is detachably connected to the second locking component 22, and the anti-rotation component 31 is respectively abutted against the elastic component 32 and the stop component 33 on two opposite sides in the axial direction X; the anti-rotation component 31 and the stop component 33 can switch between a disengaged state and a locked state through relative movement along the axial direction X.

[0114] The anti-rotation member 31 and the second locking member 22 are detachably connected, and the anti-rotation member 31 can be sleeved on the second locking member 22, and the second locking member 22 can be set as a polygon or a matching concave-convex structure is set between the two so that the anti-rotation member 31 and the second locking member 22 can rotate synchronously in the circumferential direction, and the anti-rotation member 31 can move relative to the second locking member 22 along the axial direction X.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] 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.

[0120] Optionally, when setting the elastic member 32, 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 torsion can be reduced, thereby extending the service life and improving the overall reliability of the anti-rotation assembly 30.

[0121] In some optional embodiments, the anti-rotation member 31 and the stop member 33 are respectively provided with meshing teeth 311 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.

[0122] On the basis of the mutual coupling between the anti-rotation member 31 and the stop member 33 , both of them may be provided with meshing teeth 311 , and the meshing teeth 311 respectively provided on the two members can mesh with each other and realize the connection and fixation in the circumferential direction.

[0123] 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.

[0124] The anti-rotation member 31 and the stop member 33 are arranged to be connected by meshing between teeth so that the locking between the anti-rotation member 31 and the stop member 33 is 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 mesh with the stop member 33 to be positioned, eliminating the step of finding a corresponding position for docking, thereby improving the reliability of the locking mechanism 100. In some optional embodiments, the second locking member 22 is provided with a connecting hole 221 extending in the axial direction, and a portion of the first locking member 21 extends into the connecting hole 221 and is threadedly connected to the second locking member 22.

[0125] 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. By providing the connection hole 221 with a thread, the function of the second locking member 22 rotating to drive the first locking member 21 to move axially can be conveniently realized.

[0126] 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.

[0127] Optionally, in the radial direction of the first locking member 21, the orthographic projection of the connecting hole 221 may at least partially overlap with the orthographic projection of the elastic member 32, so as to reduce the space required for the locking mechanism 100 as a whole in this direction by sharing the space in the axial direction X, thereby improving the practicality of the locking mechanism 100.

[0128] In some optional embodiments, the first locking member 21 includes a locking rod 211 and a pressure head 212, the pressure head 212 is connected to one end of the locking rod 211 along the axial direction X and is located on the outside of the base 10, and the end of the locking rod 211 away from the pressure head 212 is accommodated in the base 10 and connected to the second locking member 22; the outer peripheral surface of the pressure head 212 includes a first surface 213 and a second surface 214, and in the radial direction of the first locking member 21, the minimum distance between the first surface 213 and the locking rod 211 is greater than the minimum distance between the second surface 214 and the locking rod 211.

[0129] Optionally, the first locking member 21 includes a locking rod 211 and a pressing head 212 , wherein one end of the locking rod 211 is connected to the pressing head 212 , and the two can be welded or integrally arranged, and the other end of the locking rod 211 is connected to the second locking member 22 .

[0130] Optionally, the press head 212 has a first surface 213 that protrudes radially from the second surface 214, that is, at least a portion of the press head 212 protrudes radially from an adjacent area. In a cross section perpendicular to the axial direction X, the cross-sectional shape 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, the press head 212 can be pressed against the surface of the target component by rotating it to a certain angle.

[0131] Optionally, when setting the limiting groove, limiting pin and other components 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°; 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.

[0132] 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°.

[0133] Optionally, a sealing groove and a sealing ring at least partially embedded in the sealing groove may be provided on one side surface of the base 10 facing the pressure head 212. The sealing groove may be annular and arranged around the locking rod 211. The sealing ring may be made of rubber and is used to prevent external dust and other impurities from entering the accommodating cavity formed by the base 10.

[0134] Optionally, the diameter of the sealing ring may be smaller than the maximum diameter of the pressure head 212 .

[0135] In the second aspect, according to an embodiment of the present application, a battery 200 is proposed, including a box body 40, a battery cell 50 and a locking mechanism 100 in any embodiment of the first aspect, wherein a plurality of battery cells 50 are arranged in the box body 40, and a base 10 in the locking mechanism 100 is connected to the box body 40.

[0136] In some embodiments, the battery 200 includes a plurality of battery cells 50 and a case 40 for accommodating and supporting the battery cells 50 . The case 40 is provided with a locking mechanism 100 for connecting the battery 200 to an external component.

[0137] Optionally, the base 10 in the locking mechanism 100 is connected to the box body 40 , and the target component can be clamped between the first locking member 21 and the base 10 through the first locking member 21 , thereby achieving connection with an external component.

[0138] Optionally, the locking mechanism 100 may be installed on the longitudinal beam and / or transverse beam of the box body 40 by threading, riveting, welding or other methods.

[0139] In some optional embodiments, the box body 40 is provided with a mounting hole 44 , and the base 10 is passed through the mounting hole 44 .

[0140] Optionally, the box body 40 has side beams extending along its edges, and the side beams may be provided with mounting holes 44 penetrating along the thickness direction. One or more mounting holes 44 may be provided at the same time, and these mounting holes 44 may be evenly spaced around the circumference of the box body 40 .

[0141] Optionally, the base 10 is passed through the mounting hole 44, and is detachably connected to the box body 40 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 40, 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.

[0142] See also Figure 7 , Figure 7 for Figure 3 Another cross-sectional view at A-A' is shown. In a 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 at 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.

[0143] 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.

[0144] 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 40 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.

[0145] The connection between the battery 200 and the fixing member 500 in the vehicle body can be made more stable and reliable by providing the locking mechanism 100, and the first locking member 21 can be extended into a closed cavity having only a connection hole for connection, which has good applicability.

[0146] 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 on the outside of the base 10, and the end of the locking rod 211 away from the pressing head 212 is connected to the second locking member 22; the fixing member 500 is provided with a fixing hole 60, and the pressing head 212 is configured to be able to pass through the fixing hole 60; in the first direction Y, the size of the pressing head 212 is larger than the size of the fixing hole 60; in the second direction Z, the size of the pressing head 212 is smaller than the size of the fixing hole 60, 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.

[0147] 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.

[0148] 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 60 of the fixing member 500. When locking, the first locking member 21 is rotated by a certain angle. After the rotation, its orthographic projection on the axial direction X can overlap with part of the area around the fixing hole 60.

[0149] 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 60, and in the second direction Z, the size of the pressing head 212 can be made smaller than the fixing hole 60, so that the pressing head 212 can pass through the fixing hole 60 and can be rotated to have a certain size of clamping area between the pressing head 212 and the fixing member 500.

[0150] Taking the example that the pressing head 212 is a rectangular parallelepiped and the fixing hole 60 is a rectangular hole, the length of the pressing head 212 should be smaller than the length of the fixing hole 60, and the width of the pressing head 212 should be smaller than the width of the fixing hole 60, so that the pressing head 212 can pass through the fixing hole 60. 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 60, so that the two ends of the pressing head 212 can be pressed tightly on the fixing member 500.

[0151] The battery 200 and the vehicle 1000 provided in the embodiment of the present application have all the beneficial effects of the locking mechanism 100 in any of the embodiments of the first aspect mentioned above. For details, please refer to the specific description of the locking mechanism 100 in the above embodiments, and this embodiment will not be repeated here.

[0153] The vehicle 1000 includes a battery 200, and is locked and connected or unlocked and disassembled by a locking mechanism 100. Specifically, during the unlocking process, the vehicle 1000 can be moved to a battery swap station, the battery swap equipment of the battery swap station rises, and the locking and unlocking mechanism 600 in the battery swap equipment lifts the anti-rotation part 31 and engages with the second locking part 22, and the anti-rotation part 31 compresses the elastic part 32 and disengages from the stopper 33 along the axial direction X.

[0154] 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.

[0155] Finally, the unlocking mechanism 600 descends and disengages from the second locking member 22 and the anti-rotation member 31, and the battery 200 is removed from the chassis of the vehicle 1000. The battery exchange equipment transfers the battery 200 to the battery compartment and receives the fully charged battery.

[0156] Correspondingly, during the locking process, the battery 200 can be lifted by the battery replacement device, and the pressure head 212 can pass through the fixing hole 60 on the fixing member 500, and the locking and unlocking mechanism 600 lifts the anti-rotation member 31 and engages with the second locking member 22, and the anti-rotation member 31 compresses the elastic member 32 and disengages from the stop member 33;

[0157] Subsequently, the locking and unlocking mechanism 600 rotates the second locking member 22 and the second locking member 22 drives the first locking member 21 to move. Optionally, the locking member 21 is first rotated and then linearly descended along the axial direction X until the pressure head 212 is tightly pressed on the fixing 500.

[0158] 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.

[0159] Optionally, the locking and unlocking mechanism 600 can be applied to a battery swap station that provides services for electric devices such as the vehicle 1000.

[0163] II) The battery exchange device transfers the removed battery 200 to be charged to the battery compartment for charging, and receives the fully charged battery 200 stored in the battery compartment;

[0164] III) The battery exchange device moves with the fully charged battery 200 to the lower side of the vehicle 1000, and the unlocking mechanism 600 locks the first locking member 21 in the fully charged battery 200 to the fixing member 500 of the vehicle body, so as to install the fully charged battery 200 on the vehicle 1000;

[0165] IV) The vehicle 1000 leaves the supporting platform.

[0166] 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.

[0167] In some embodiments, the support platform includes a lifting mechanism, which is used to lift the vehicle 1000 to facilitate moving the battery exchange equipment to the lower side of the vehicle 1000.
