Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.

The following disclosure provides many different embodiments, or examples, for implementing different structures of the invention. In order to simplify the present disclosure, components and arrangements of specific examples are described below. They are, of course, merely examples and are not intended to limit the invention. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. In addition, the present invention provides examples of various specific processes and materials, but one of ordinary skill in the art will recognize the applicability of other processes and/or the use of other materials.

Next, referring to the drawings, a power conversion platform 100 according to an embodiment of the present invention is described.

As shown in fig. 1-6 and 8-10, the power conversion platform 100 includes a lifting device 1, where the lifting device 1 includes a first lifting assembly 11 and a second lifting assembly 12 disposed at intervals along a first horizontal direction (e.g., a left-right direction in fig. 1), and the first lifting assembly 11 and the second lifting assembly 12 are used to drive the vehicle 101 to lift the vehicle 101 to a suitable height position, so as to facilitate a power conversion operation of the vehicle 101 at a suitable position, and so on. For example, when the vehicle 101 travels to the power exchanging platform 100 for power exchanging, the vehicle 101 may be located between the first lifting assembly 11 and the second lifting assembly 12, such that the first lifting assembly 11 and the second lifting assembly 12 are respectively located at two sides of the vehicle 101 in the first horizontal direction, so as to drive the vehicle 101 to lift together.

One of the first lifting assembly 11 and the second lifting assembly 12 defines an avoidance channel 11a, the avoidance channel 11a is configured to allow the battery 1011 of the vehicle 101 to move from the outer side of the lifting device 1 to between the first lifting assembly 11 and the second lifting assembly 12 during the power change operation, for example, in fig. 1, the first lifting assembly 11 defines the avoidance channel 11a, the avoidance channel 11a may allow the battery 1011 to move from the side of the first lifting assembly 11 away from the second lifting assembly 12 to the side of the first lifting assembly 11 facing the second lifting assembly 12, and may also allow the battery 1011 to move from the side of the first lifting assembly 11 facing the second lifting assembly 12 to the side of the first lifting assembly 11 facing away from the second lifting assembly 12, so that the battery 1011 can be transported by the level changing platform 100 through the avoidance channel 11a during the power change operation of the vehicle 101, for example, the battery 1011 detached from the vehicle 101 can be transported from between the first lifting assembly 11 and the second lifting assembly 12 to the outer side of the lifting device 1, thereby reducing the space required by the new lifting assembly 11 to the first lifting assembly 11, and simultaneously reducing the space required by the first lifting assembly 101 to be occupied by the battery 1011, and the additional lifting assembly 1 is avoided.

The other one of the first lifting assembly 11 and the second lifting assembly 12 is opposite to the avoidance channel 11a, the other one of the first lifting assembly 11 and the second lifting assembly 12 comprises a scissor 121 and a driving mechanism 122, the scissor 121 comprises a first scissor arm 1211 and a second scissor arm 1212 which are arranged in a crossed mode and are connected in a pivoted mode, the driving mechanism 122 is used for driving the scissor 121 to be unfolded or folded to adjust the height of the scissor 121 in the up-down direction, and in the process that the driving mechanism 122 drives the scissor 121 to be unfolded or folded, the included angle of the first scissor arm 1211 and the second scissor arm 1212 at the pivot position is changed, so that the height of the scissor 121 in the up-down direction is adjusted, and in turn, the scissor 121 is lifted up and down by the vehicle 101. Wherein, pivot axis between first scissors arm 1211 and second scissors arm 1212 is parallel with first horizontal direction, is favorable to reducing the occupation of space between scissors fork 121 to first lifting subassembly 11 and second lifting subassembly 12 in first horizontal direction, is favorable to reducing the occupation of space of scissors fork 121 to its one side that deviates from dodging passageway 11 in first horizontal direction simultaneously to be favorable to reducing the occupation space of scissors fork 121 in first horizontal direction, be favorable to further reducing lifting device 1's occupation space, and then can be convenient for change level 100 to reduce self occupation space.

For example, in the example of fig. 1 and 2, the first lift assembly 11 defines a relief passage 11a, the second lift assembly 12 is disposed opposite the relief passage 11a in a first horizontal direction, and the second lift assembly 12 includes a scissor fork 121 and a drive mechanism 122; when at least one of the first and second scissor arms 1211 and 1212 rotates about the pivot position of the two, if the angle between the portion of the first scissor arm 1211 located on the upper side of the pivot position and the portion of the second scissor arm 1212 located on the upper side of the pivot position is reduced, the distance between the upper and lower ends of each of the first and second scissor arms 1211 and 1212 is increased, the expansion of the scissors 121 is achieved, and if the angle between the portion of the first scissor arm 1211 located on the upper side of the pivot position and the portion of the second scissor arm 1212 located on the upper side of the pivot position is increased, the distance between the upper and lower ends of each of the first and second scissor arms 1211 and 1212 is reduced, the retraction of the scissors 121 is achieved. Of course, in other examples, the second lift assembly 12 defines the escape passage 11a, the first lift assembly 11 is disposed opposite the escape passage 11a along the first horizontal direction, and the first lift assembly 11 includes the scissors fork 121 and the drive mechanism 122.

In addition, since one of the first lifting assembly 11 and the second lifting assembly 12 defines the escape passage 11a, and the other one is disposed opposite to the escape passage 11a and includes the scissors fork 121 and the driving mechanism 122, in the case that the center position of the first lifting assembly 11 and the center position of the second lifting assembly 12 are spaced apart from each other by a certain distance, the above arrangement of the present application facilitates providing a larger vehicle placement space between the first lifting assembly 11 and the second lifting assembly 12, so that the level shifter 100 is adapted to different vehicles 101.

According to the power conversion platform 100 of the embodiment of the invention, the pivot axis between the first scissor arm 1211 and the second scissor arm 1212 is parallel to the first horizontal direction, and the first scissor arm 1211 and the second scissor arm 1212 lift the vehicle 101 in the up-down direction, so that the occupied space of the scissors fork 121 in the first horizontal direction is reduced, the occupied space of the lifting device 1 is further reduced, and the power conversion platform 100 can reduce the occupied space of the power conversion platform itself.

In some embodiments, as shown in fig. 3-4, the other of the first lifting assembly 11 and the second lifting assembly 12 further includes a supporting table 123, the supporting table 123 is disposed on top of the scissors fork 121, the supporting table 123 is adapted to support the vehicle 101, the scissors fork 121 may support the supporting table 123, and at the same time, the height of the supporting table 123 in the up-down direction may be adjusted by expanding or retracting the scissors fork 121, so that the supporting table 123 may be lifted to lift the vehicle 101.

In some embodiments, as shown in fig. 3, a third slide rail extending in a second horizontal direction (e.g., a front-rear direction in fig. 3) is provided at a lower side of the support table 123, and an upper end of the first scissor arm 1211 is slidably engaged with the third slide rail in the second horizontal direction. The third slide rail may guide the movement of the upper end of the first scissor arm 1211, ensuring that the upper end of the first scissor arm 1211 moves in the second horizontal direction. For example, the bottom surface of the upper end of the first scissor arm 1211 may be formed with a third runner, which may mate with a third slide rail. The upper end of the second scissor arm 1212 is hinged to the lower side of the supporting base 123, and the second scissor arm 1212 can rotate relative to the supporting base 123.

In some embodiments, as shown in fig. 3-4, the drive mechanism 122 includes a first drive 1221, a support 1222, and a support wheel 1223, the support 1222 coupled to the first drive 1221 for movement by the first drive 1221 in a second horizontal direction (e.g., a front-to-back direction in fig. 3), the support 1222 having a support surface 1222a, the support surface 1222a extending downward from above in the second horizontal direction, the second horizontal direction being perpendicular to the first horizontal direction; the supporting wheel 1223 is rotatably disposed at the crossing position of the first scissor arm 1211 and the second scissor arm 1212, and the supporting wheel 1223 is supported on the supporting surface 1222a, and the supporting surface 1222a may guide the supporting wheel 1223. When the first driver 1221 drives the rack 1222 to move along the second horizontal direction, the supporting wheel 1223 rolls or slides along the extending direction of the supporting surface 1222a, so that the height of the supporting wheel 1223 in the up-down direction changes, and the supporting wheel 1223 drives the scissors 121 to move to expand or retract the scissors 121, thereby adjusting the height of the scissors 121 in the second horizontal direction.

Alternatively, the path of extension of the support surface 1222a may be straight or curved.

For example, when the extending path of the supporting surface 1222a is a straight line, the supporting surface 1222a extends obliquely in the up-down direction, so that the lifting height of the supporting wheel 1223 and the amount of change in the position of the support 1222 in the second horizontal direction are substantially in a linear relationship, the lifting height of the supporting wheel 1223 can be adjusted by the amount of movement of the support 1222 in the second horizontal direction, and the degree of expansion or retraction of the scissors 121 can be changed by the change in the lifting height of the supporting wheel 1223, so that the lifting height of the scissors 121 in the up-down direction, that is, the lifting height of the scissors 121 is changed, and further, the lifting height of the scissors 121 can be adjusted by the amount of movement of the supporting surface 1222a in the second horizontal direction, so that the lifting height of the scissors 121 can be controlled by the driving mechanism 122. For example, the support wheel 1223 may be moved at a uniform speed along the extending direction of the support surface 1222a by moving the support 1222 at a uniform speed along the second horizontal direction, so as to implement uniform speed adjustment of the lifting height of the scissor fork 121; variable speed adjustment of the elevation of scissors fork 121 may also be accomplished by variable speed movement of carriage 1222 in a second horizontal direction to cause variable speed movement of support wheel 1223 in the direction of extension of support surface 1222 a.

For example, the extending path of the supporting surface 1222a is curved, so that the lifting height of the supporting wheel 1223 and the position variation of the bracket 1222 along the second horizontal direction can be in a nonlinear relationship, when the position variation of the bracket 1222 along the second horizontal direction is constant, the supporting wheel 1223 rolls to the position where the supporting surface 1222a is steeper, the lifting height variation of the supporting wheel 1223 is greater, and the rapid adjustment of the height of the vehicle 101 can be realized; when the supporting wheel 1223 rolls to the position where the supporting surface 1222a is slower, the variation of the lifting height of the supporting wheel 1223 is smaller, and the scissor fork 121 can lift the heavier vehicle 101 under the action of the first driver 1221 with the same power, so that the driving mechanism 122 is easier in the process of starting to lift the vehicle 101, and the control of the lifting height of the scissor fork 121 by the driving mechanism 122 is convenient to realize.

In some embodiments, as shown in fig. 3-4, the scissors fork 121 further comprises a first pin 124, the intersection of the first scissor arm 1211 and the second scissor arm 1212 is perforated with the first pin 124, the first scissor arm 1211 and the second scissor arm 1212 are rotatably connected with the first pin 124, or one of the first scissor arm 1211 and the second scissor arm 1212 is fixed with the first pin 124, and the other is rotatably connected with the first pin 124. When both the first and second scissor arms 1211 and 1212 rotate about the first pin 124, the angle between the portion of the first scissor arm 1211 above the first pin 124 and the portion of the second scissor arm 1212 above the first pin 124 changes, which changes the height of the upper end of each of the first and second scissor arms 1211 and 1212 in the up-down direction relative to the lower end, thereby expanding or collapsing the scissors fork 121. For example, when the angle between the portion of first scissor arm 1211 above first pin 124 and the portion of second scissor arm 1212 above first pin 124 becomes smaller, the height of the upper end of first scissor arm 1211 relative to the lower end of second scissor arm 1212 increases, causing scissors fork 121 to expand; when the angle between the portion of the first scissor arm 1211 above the first pin 124 and the portion of the second scissor arm 1212 above the first pin 124 becomes larger, the height of the upper end of the first scissor arm 1211 relative to the lower end of the second scissor arm 1212 is reduced, such that the scissors fork 121 is retracted.

Of course, the supporting wheel 1223 and the first pin 124 may also be fixedly connected.

For example, in the example of fig. 2 to 4, the supporting table 123 is provided at the top of the scissors fork 121, when the supporting table 123 needs to be lifted, the first driver 1221 drives the bracket 1222 to move forward along the second horizontal direction, so that the supporting wheel 1223 moves upwards under the pushing of the supporting surface 1222a, the supporting wheel 1223 rises in the up-down direction, and drives the first pin 124 to rise, the first scissor arm 1211 and the second scissor arm 1212 both rotate around the first pin 124, the included angle between the portion of the first scissor arm 1211 above the first pin 124 and the portion of the second scissor arm 1212 above the first pin 124 becomes smaller, and the scissors fork 121 expands, so that the supporting table 123 can rise in the up-down direction; and when the support wheel 1223 rolls to the uppermost end of the support surface 1222a, the support table 123 is lifted to the uppermost position. When the supporting table 123 needs to be lowered, the first driver 1221 drives the bracket 1222 to move reversely along the second horizontal direction, so that the supporting wheel 1223 moves downward under the support of the supporting surface 1222a, the supporting wheel 1223 lowers in height in the up-down direction, and drives the first pin shaft 124 to lower, the first and second scissor arms 1211 and 1212 rotate around the first pin shaft 124, the included angle between the portion of the first scissor arm 1211 above the first pin shaft 124 and the portion of the second scissor arm 1212 above the first pin shaft 124 becomes larger, and the scissors fork 121 is retracted, so that the height of the supporting table 123 in the up-down direction can be lowered; and when the support wheel 1223 rolls to the lowermost end of the support surface 1222a or the support wheel 1223 comes out of contact with the support surface 1222a, the support table 123 is lowered to the lowermost position.

Further, the driving mechanism 122 can control the movement amount of the rack 1222b by the number of turns of the driving motor 1221b, thereby controlling the movement amount of the stand 1222. And the extending path of the supporting surface 1222a on the bracket 1222 is a straight line, so that the lifting height of the supporting wheel 1223 and the position variation of the supporting wheel 1223 along the extending direction of the supporting surface 1222a are approximately in a linear relationship, and the lifting height of the supporting table 123 can be adjusted by the moving amount of the bracket 1222 relative to the supporting wheel 1223, so that the control of the lifting height of the supporting table 123 by the driving mechanism 122 is facilitated. Therefore, the driving mechanism 122 can control the movement amount of the bracket 1222 through the rotation number of the driving motor 1221b, so that the lifting height of the supporting table 123 can be further adjusted, and the driving mechanism 122 can conveniently control the lifting height of the supporting table 123.

For example, the driving motor 1221b may be fixed to the supporting seat 125 through a motor mount, thereby ensuring stability and reliability of the driving motor 1221b in operation.

It can be appreciated that, after the locking and unlocking mechanism 22 completes the locking and unlocking process of the lock body 1012 and is separated from the lock body 1012, the first ball 2221 moves towards the lowest point of the tapered slot 221a under the action of the second elastic member 225, and the lowest point of the tapered slot 2221a corresponds to the axis of the rotating seat 221, so that the first ball 2221 moves towards the axis of the rotating seat 221 under the action of the second elastic member 225, and the first ball 2221 drives the floating sleeve 222 to move towards the axis of the rotating seat 211, so as to realize centering of the floating sleeve 222, and thus the floating sleeve 222 can perform the next floating adjustment. Wherein, it is referred to that the axis of the floating shaft sleeve 222 coincides with the axis of the rotating seat 221.

The pressing piece 2222 is used for separating the first elastic element 224 and the second elastic element 225, so that the force for driving the first ball 2221 to move towards the lowest point of the conical groove 221a is provided by the second elastic element 225, and the floating shaft sleeve 222 needs to float against the elastic force of the second elastic element 225, so that the phenomenon that the floating shaft sleeve 222 is not easy to float due to the overlarge elastic force of the first elastic element 224 is avoided, and the floating effect of the floating shaft sleeve 222 is improved.

In addition, since one end of the first elastic member 224 abuts against the pressing member 2222 to drive the pressing member 2222 to move towards the bottom wall of the mounting groove 222a, when the floating shaft sleeve 222 is centered, the pressing member 2222 abuts against the bottom wall of the mounting groove 222a, and the second elastic member 225 is kept in a pre-tightening state all the time, so that the second elastic member 225 always drives the first ball 2221 to move towards the lowest point of the tapered groove 221a, and the centering effect of the floating shaft sleeve 222 is ensured.

The process of the locking and unlocking mechanism 22 is as follows: the floating shaft sleeve 222 moves in a plane perpendicular to the axial direction of the rotating seat 221, under the action of the second elastic piece 225, the axis of the floating shaft sleeve 222 is overlapped with the axis of the lock body 1012, meanwhile, under the action of the first elastic piece 224, the locking and unlocking piece 223 is reliably matched with the lock body 1012, the driving device provides power for the rotating seat 221, the rotating seat 221 circumferentially rotates along the rotating seat 221, the rotating seat 221 can drive the floating shaft sleeve 222 to circumferentially rotate along the rotating seat 221, and the floating shaft sleeve 222 can drive the locking and unlocking piece 223 to circumferentially rotate along the rotating seat 221. Thus, the lock release member 223 can screw the lock body 1012 of the battery 1011 or loosen the lock body 1012 of the battery 1011. After the locking and unlocking mechanism 22 completes the locking and unlocking process of the lock body 1012 and is separated from the lock body 1012, the second elastic member 225 is pre-tensioned between the pressing piece 2222 and the rotating seat 221, so that the first ball 2221 applies pressure to the floating shaft sleeve 222, and the floating shaft sleeve 222 is close to the axis of the rotating seat 221 in the plane perpendicular to the axial direction of the rotating seat 221, so that the locking and unlocking member 223, the floating shaft sleeve 222 and the rotating seat 221 can be kept on the same axis, and the centering of the floating shaft sleeve 222 is realized, so that the floating shaft sleeve 222 can perform the next floating adjustment.

In some embodiments, as shown in fig. 13 and 15, the rotating base 221 has a receiving groove 221b, the tapered groove 221a is disposed on a bottom wall of the receiving groove 221b, and at least a portion of the floating sleeve 222 is disposed in the receiving groove 221 b. Therefore, the structure of the locking and unlocking mechanism 22 is more compact, so that the axial size of the locking and unlocking mechanism 22 is reduced, and the locking and unlocking mechanism 22 is more flexible.

In some embodiments, as shown in fig. 13, 14 and 16, the power conversion platform 100 further includes a floating adjustment ring 226, where the floating adjustment ring 226 is disposed between the floating sleeve 222 and the rotating base 221, the floating adjustment ring 226 is movable relative to the rotating base 221 along a fourth horizontal direction (e.g., a direction in fig. 14), the fourth horizontal direction is perpendicular to an axial direction of the rotating base 221, and the floating sleeve 222 is movable relative to the floating adjustment ring 226 along a fifth horizontal direction (e.g., b direction in fig. 14), and the fifth horizontal direction is perpendicular to the fourth horizontal direction and an axial direction of the rotating base 221 (e.g., up-down direction in fig. 11), respectively. Thus, the floating adjustment ring 226 allows the floating collar 222 to be floatingly adjusted with respect to the swivel base 221 in the fourth and fifth horizontal directions.

It is understood that the fourth horizontal direction may be the same as the first horizontal direction, or the same as the second horizontal direction, or different from both the first horizontal direction and the second horizontal direction.

In some embodiments, as shown in fig. 15 and 16, the rotating base 221 has two first limiting grooves 221c, the two first limiting grooves 221c are arranged along the fourth horizontal direction and are respectively located at two opposite sides of the axis of the rotating base 221, the floating adjusting ring 226 has two first limiting blocks 226a, and the two first limiting blocks 226a are respectively located in the two first limiting grooves 221c and are movable along the fourth horizontal direction.

It is understood that the two first limiting blocks 226a and the two first limiting grooves 221c cooperate with each other to limit the floating adjustment ring 226 to move in the fifth horizontal direction relative to the rotating base 221, so as to prevent the floating adjustment ring 226 and the rotating base 221 from rotating relative to each other. The length of the first limiting block 226a along the fourth horizontal direction is smaller than the length of the first limiting groove 221c along the fourth horizontal direction, and the two first limiting blocks 226a are respectively disposed in the two first limiting grooves 221c and are movable along the fourth horizontal direction, so that the floating shaft sleeve 222 can move along the fourth horizontal direction relative to the rotating seat 221, thereby realizing floating adjustment along the fourth horizontal direction.

In some embodiments, as shown in fig. 13, 16 and 17, the floating shaft sleeve 222 has two second limiting grooves 222c, the two second limiting grooves 222c are arranged along the fifth horizontal direction and are respectively located at two opposite sides of the axis of the rotating seat 221, and the floating adjusting ring 226 has two second limiting blocks 226b.

It will be appreciated that the two second limiting grooves 222c and the two second limiting blocks 226b cooperate with each other to limit the floating collar 222 from moving in the fourth horizontal direction relative to the floating adjustment ring 226, so that the floating collar 222 and the floating adjustment ring 226 are prevented from rotating relative to each other along the circumferential direction of the rotating base 221, and the floating adjustment ring 226 and the rotating base 221 are prevented from rotating relative to each other along the circumferential direction of the rotating base 221, so that the locking and unlocking mechanism 22 can operate normally.

Further, the length of the second limiting block 226b along the fifth horizontal direction is smaller than the length of the second limiting groove 222c along the fifth horizontal direction, and the two second limiting blocks 226b are respectively disposed in the two second limiting grooves 222c and are movable along the fifth horizontal direction, so that the floating shaft sleeve 222 can move along the fifth horizontal direction relative to the floating adjusting ring 226.

When the floating collar 222 moves in the fifth horizontal direction with respect to the floating adjustment ring 226, the floating collar 222 can move in the fifth horizontal direction with respect to the rotating base 221 because the floating adjustment ring 226 is restricted from moving in the fifth horizontal direction with respect to the rotating base 221, thereby realizing floating adjustment of the floating collar 222 in the fifth horizontal direction.

When the floating adjustment ring 226 moves along the fourth horizontal direction relative to the rotating seat 221, the floating sleeve 222 is limited to move along the fourth horizontal direction relative to the floating adjustment ring 226, so that the floating adjustment ring 226 drives the floating sleeve 222 to move along the fourth horizontal direction, and the floating adjustment of the floating sleeve 222 along the fourth horizontal direction is realized.

In some embodiments, as shown in fig. 13, 14 and 16, the floating adjustment ring 226 is provided with a plurality of first through holes 226c, the plurality of first through holes 226c are disposed at intervals in the circumferential direction of the floating adjustment ring 226, and the first through holes 226c penetrate the floating adjustment ring 226 in the axial direction of the rotation seat 221. The locking and unlocking mechanism 22 further includes a plurality of second balls 226d, the plurality of second balls 226d are respectively disposed in the plurality of first through holes 226c, upper and lower ends of the second balls 226d respectively extend out of the first through holes 226c, and the second balls 226d respectively abut against the floating sleeve 222 and the rotating seat 221.

It will be appreciated that the first through-hole 226c is configured to receive the second ball 226d and limit movement of the second ball 226d relative to the floating adjustment ring 226, and that the first through-hole 226c has a depth in the axial direction of the swivel base 221 that is less than the diameter of the second ball 226d such that the second ball 226d may extend out of the first through-hole 226c and abut the floating collar 222 and the swivel base 221.

Therefore, when the floating adjusting ring 226 drives the floating shaft sleeve 222 to move along the fourth horizontal direction, the floating adjusting ring 226 and the floating shaft sleeve 222 form a whole, and the second balls 226d enable rolling friction between the floating adjusting ring 226 and the rotating seat 21 and between the floating shaft sleeve 222 and the rotating seat 221 respectively, so that friction resistance is small, the floating adjusting ring 226 and the floating shaft sleeve 222 move along the fourth horizontal direction relatively to the rotating seat 221 more smoothly, and accordingly the floating effect of the floating adjusting ring 226 and the floating shaft sleeve 222 along the fourth horizontal direction is good. When the floating shaft sleeve 222 moves along the fifth horizontal direction relative to the floating adjusting ring 226, the second balls 226d make rolling friction between the floating shaft sleeve 222 and the floating adjusting ring 226, so that the friction resistance is small, and the floating shaft sleeve 222 moves along the fifth horizontal direction relative to the floating adjusting ring 226 more smoothly, so that the floating effect of the floating shaft sleeve 222 along the fifth horizontal direction is good.

In some embodiments, as shown in fig. 13, 14 and 17, the locking and unlocking mechanism 22 further includes a cover plate 227, where the cover plate 227 is disposed around the floating shaft sleeve 222, the cover plate 227 is connected to the rotating base 221, and a limiting plate 222d is disposed on an outer peripheral wall of the floating shaft sleeve 222, where the limiting plate 222d is located between the cover plate 227 and the rotating base 221. It will be appreciated that the cover plate 227 serves to protect the internal structure of the swivel base 221, while also limiting the movement of the floating bushing 222 in the axial direction of the swivel base 221. As shown in fig. 13, 14 and 19, the locking and unlocking mechanism 22 further includes a rolling ring 228 and a plurality of third balls 228c, the rolling ring 228 is sleeved on the floating shaft sleeve 222, the rolling ring 228 is located between the limiting plate 222d and the cover plate 227, the rolling ring 228 is provided with a plurality of third through holes 228a spaced apart along the circumferential direction of the rolling ring 228, each third through hole 228a penetrates the rolling ring 228 in the axial direction of the rolling ring 228, the plurality of third balls 228c are respectively arranged in the plurality of third through holes 228a, the depth of the third through holes 228a in the axial direction of the rolling ring 228 is smaller than the diameter of the third balls 228c, and the third balls 228c are respectively abutted against the cover plate 227 and the limiting plate 222 d.

It will be appreciated that the third through hole 228a may limit the relative movement between the third ball 228c and the rolling ring 228, and meanwhile, since the depth of the third through hole 228a in the axial direction of the rolling ring 228 is smaller than the diameter of the third ball 228c, the third ball 228c may extend out of the third through hole 228a and abut against the cover plate 227 and the limiting plate 222d, respectively, so that when the floating sleeve 222 moves in the fourth horizontal direction or the fifth horizontal direction, the third ball 228c causes rolling friction between the cover plate 227 and the limiting plate 222d, and the friction resistance is small, so that the floating sleeve 222 moves in the fourth horizontal direction or the fifth horizontal direction more smoothly, thereby improving the floating effect of the floating sleeve 222.

In some embodiments, as shown in fig. 17, a side of the limiting plate 222d facing the rolling ring 228 has a limiting protrusion 222e, and the rolling ring 228 is provided with a limiting notch 228b matching the limiting protrusion 222 e. Thereby, the rolling ring 228 and the floating collar 222 can be kept relatively fixed in the circumferential direction, thereby improving the floating effect of the floating collar 222.

In some embodiments, as shown in fig. 11, 14, 17 and 20, the floating collar 222 is provided with two first connection holes 222f opposite to each other in the radial direction of the floating collar 222, each first connection hole 222a penetrates the floating collar 222 in the radial direction, and the diameters of the two first connection holes 222f are the same. The locking and unlocking member 223 is provided with a second connecting hole 223a penetrating through the locking and unlocking member 223 in the radial direction of the locking and unlocking member 223, the second connecting hole 223a extends along the moving direction of the locking and unlocking member 223, the locking and unlocking mechanism 22 further comprises a first limit shaft 2233, and the first limit shaft 2233 penetrates through the first connecting hole 222f and the second connecting hole 223a so as to avoid the separation of the locking and unlocking member 223 and the floating shaft sleeve 222.

In actual installation, a part of the locking and unlocking member 223 may be inserted into the installation groove 222a, so that the second connection holes 223a in the locking and unlocking member 223 are aligned with the two first connection holes 222f, and then the first limiting shaft 2233 is inserted into the second connection holes 223a and the two first connection holes 222f.

When the locking and unlocking member 223 moves in the mounting groove 222a along the axial direction of the rotating seat 221, the movement distance of the locking and unlocking member 223 is determined by the cooperation of the second connecting hole 223a and the first limiting shaft 2233, namely, the maximum movement distance of the locking and unlocking member 223 does not exceed the length of the second connecting hole 223a, and when the first limiting shaft 2233 abuts against the end part of the second connecting hole 223a, the locking and unlocking member 223 stops moving continuously along the axial direction of the rotating seat 221, so that the locking and unlocking member 223 can move in the floating shaft sleeve 222 stably and the connection between the locking and unlocking member 223 and the floating shaft sleeve 222 is realized.

In some embodiments, as shown in fig. 14 and 20, the locking and unlocking member 223 includes a tightening shaft 2231 and a sleeve 2232, the tightening shaft 2231 being movably disposed in the mounting groove 222a in the axial direction of the rotation seat 221, the sleeve 2232 being connected to an end of the tightening shaft 2231 remote from the floating collar 222.

It can be appreciated that the tightening shaft 2231 moves in the mounting groove 222a along the axial direction of the rotating seat 221, the tightening shaft 2231 is connected with the sleeve 2232, the tightening shaft 2231 can drive the sleeve 2232 to move along the axial direction of the rotating seat 221, and one end of the sleeve 2232 away from the floating shaft sleeve 222 is used for matching with the lock body 1012 of the power battery 1011, so that the locking and unlocking piece 223 can be connected with the lock body 1012 of the power battery 1011, thereby realizing locking and unlocking of the lock body 1012.

Alternatively, the mounting groove 222a is a polygonal groove, and the tightening shaft 2231 is a corresponding polygonal shaft, so that the tightening shaft 2231 and the floating shaft sleeve 222 can be prevented from rotating relatively, so that the locking and unlocking member 223 can transmit torque, and the battery 1011 can be disassembled and assembled. In the example shown in fig. 17, the installation groove 222a is a quadrangular groove, and the tightening shaft 2231 is a corresponding quadrangular shaft, but the present invention is not limited thereto, and the installation groove 222a may be other polygonal grooves such as a trilateral groove, a pentagonal groove, a hexagonal groove, a heptagonal groove, or the like, and the tightening shaft 2231 may be a corresponding other polygonal shaft such as a trilateral shaft, a pentagonal shaft, a hexagonal shaft, a heptagonal shaft, or the like.

Thus, tightening shaft 2231 and sleeve 2232 can be coupled by second limiting shaft 2234 such that tightening shaft 2231 and sleeve 2232 remain relatively fixed in the axial and circumferential directions.

In the example shown in fig. 20, the tightening shaft 2231 has two third connecting holes 2231a that are axially symmetrical, and the fourth connecting hole 2232a on the sleeve 2232 corresponds to the third connecting holes 2231a one by one, when the sleeve 2232 and the tightening shaft 2231 are connected, the third connecting holes 2231a and the fourth connecting holes 2232a are aligned first, and then the second limiting shaft 2234 sequentially passes through the fourth connecting holes 2232a, the two third connecting holes 2231a and the other fourth connecting hole 2232a, so as to realize the fixed connection of the tightening shaft 2231 and the sleeve 2232.
