The following detailed description is made with reference to the accompanying drawings and examples:

referring to fig. 1 to 6 together, a vehicle provided in an embodiment of the present application includes a vehicle body, a battery pack, and a quick battery-changing mechanism, where the quick battery-changing mechanism provided in an embodiment of the present application includes a first connecting member 10, a moving member 20, a second connecting member 40, and a driving structure 50. It should be noted that, in the present embodiment, the battery quick-change mechanism is used for realizing the dismounting and mounting between the battery pack and the vehicle body, specifically, the first connecting member 10 is disposed on the vehicle body, and the second connecting member 40 is connected to the battery pack; alternatively, the first connecting member 10 is connected to the battery pack, and the second connecting member 40 is provided on the vehicle body. Wherein, according to actual user demand, battery quick change mechanism still can be used to realize the dismouting operation between other two devices.

Specifically, the moving member 20 is configured to be movable along the X axis within the first connecting member 10; the moving member 20 includes a first main body 21 and a first locking portion 22, the first locking portion 22 is disposed at one end of the first main body 21 along the X axis, and a first elastic member 30 is abutted between the other end of the first main body 21 along the X axis and the first connecting member 10; wherein the direction of the elastic force of the first elastic member 30 is substantially parallel to the X-axis. The second connecting piece 40 is provided with a second locking part 41, and the second locking part 41 can enter the first connecting piece 10 along the Y axis; the second locking portion 41 is configured to push against the first locking portion 22 when entering the first connecting member 10 along the Y axis, so that the first main body portion 21 moves along the X axis in the first connecting member 10 and presses the first elastic member 30, and the second locking portion 41 is further configured to lock with the first locking portion 22 along the Y axis when the first elastic member 30 drives the first main body portion 21 to reset.

Based on this, as shown in fig. 3, when the second locking portion 41 of the second connecting member 40 enters the first connecting member 10 along the Y axis, the second locking portion 41 pushes against the first locking portion 22 of the moving member 20 to convert the moving force along the Y axis into the pushing force along the X axis against the first locking portion 22, so that the first main body portion 21 and the first locking portion 22 move together in the first connecting member 10 along the X axis away from the second locking portion 41, so that the first main body portion 21 presses the first elastic member 30 along the X axis, and at this time, the first elastic member 30 is in the power storage state; as shown in fig. 4, when the second locking portion 41 continues to move along the Y axis in the first connecting member 10 and moves to a certain distance, the second locking portion 41 may disengage from the first locking portion 22, at this time, the pushing force of the second locking portion 41 against the first locking portion 22 is removed, the first elastic member 30 resets to drive the first main body portion 21 and the first locking portion 22 to reset and move along the X axis in the first connecting member 10, so that the first locking portion 22 moves toward the second locking portion 41 along the X axis and moves to one side of the second locking portion 41 to form a limiting locking with the second locking portion 41 along the Y axis, so that the relative positions of the first connecting member 10 and the second connecting member 40 are fixed, and the locking of the first connecting member 10 and the second connecting member 40 is realized.

The driving structure 50 is configured to be able to drive the first main body portion 21 and/or the first lock portion 22 to disengage the first lock portion 22 from the second lock portion 41 along the X axis. Alternatively, the driving structure 50 can push the first main body 21 and/or the first locking portion 22 along the Y axis, or the driving structure 50 can pull the first main body 21 and/or the first locking portion 22 along the Y axis, or the driving structure 50 can push the first main body 21 and/or the first locking portion 22 along the X axis, or the driving structure 50 can push the first main body 21 and/or the first locking portion 22 along the axis forming an included angle greater than 0 ° with the X axis and the Y axis, respectively, and each of the first locking portion 22 and the second locking portion 41 can be disengaged to unlock the first connecting member 10 and the second connecting member 40.

Based on this, as shown in fig. 5, when the first body portion 21 and/or the first locking portion 22 are driven by using the driving structure 50, the first body portion 21 and the first locking portion 22 of the moving member 20 can be moved together in the first connecting member 10 along the X axis away from the second locking portion 41, so that the first locking portion 22 is separated from the second locking portion 41 along the X axis, and thus, the locking relationship between the first locking portion 22 and the second locking portion 41 is released, that is, the first locking portion 22 and the second locking portion 41 are in the unlocked state, it can be understood that the first connecting member 10 and the second connecting member 40 are in the unlocked state, and at this time, as shown in fig. 6, the second locking portion 41 can be directly removed from the first connecting member 10, to achieve the detachment of the first connecting member 10 and the second connecting member 40, and at this time, the first elastic element 30 drives the first main body 21 and the first locking portion 22 to move along the X axis.

With this arrangement, the second locking portion 41 is pushed into the first connecting member 10 along the Y-axis until the first locking portion 22 moves under the reset of the first elastic member 30 to be locked with the second locking portion 41, namely, the first connecting member 10 and the second connecting member 40 can be locked, the driving structure 50 drives the first main body portion 21 and/or the first locking portion 22 until the first locking portion 22 is separated from the second locking portion 41, therefore, the battery quick-change mechanism provided by the embodiment of the application simplifies the disassembly and assembly operation between the first connecting piece 10 and the second connecting piece 40, so that the disassembly and assembly operation of the first connecting piece 10 and the second connecting piece 40 is time-saving and labor-saving, when the battery quick-change mechanism is applied to the disassembly and assembly between the battery pack and the vehicle body, the disassembly and assembly operation of the battery pack is facilitated to be simplified, and the disassembly and assembly efficiency of the battery pack is facilitated to be improved. Correspondingly, the vehicle that this application embodiment provided also has the dismouting easy operation of battery package, efficient advantage.

Optionally, referring to fig. 2, the number of the moving members 20 is at least two, and each moving member 20 is provided with a first locking portion 22, so that the number of the first locking portions 22 is at least two; correspondingly, the second connecting member 40 is provided with at least two second locking portions 41, and when the first connecting member 10 and the second connecting member 40 are locked, the at least two first locking portions 22 and the at least two second locking portions 41 are locked in a one-to-one correspondence manner. This arrangement contributes to improvement in reliability when the first and

second connectors

10 and 40 are locked.

It should be noted that, at least two moving members 20 can move along the X axis in the first connecting member 10, and the moving directions of any two moving members 20 can be the same or different, and can be specifically set according to the actual situation. Therefore, it is understood that the X axis refers to an axis perpendicular to the Y axis, that is, the X axis is any axis on a plane perpendicular to the Y axis, and the extending direction of the axis is not limited; illustratively, when the Y-axis is an axis in the vertical direction, then the X-axis is any axis perpendicular to the Y-axis in the horizontal plane.

In an embodiment, referring to fig. 5 to 10, the first body 21 is formed with a first clearance groove 201, the first clearance groove 201 penetrates the first body 21 along the Y axis, and an inner sidewall of the first clearance groove 201 has a first inclined surface 202. The first connecting member 10 is provided with a second clearance groove 101, and the second clearance groove 101 is communicated with the first clearance groove 201. The driving structure 50 comprises a wedge block 51, and the wedge block 51 sequentially penetrates through the second clearance groove 101 and the first clearance groove 201 along the Y axis; wedge block 51 has a second inclined surface 5101 adapted to first inclined surface 202; the wedge block 51 is configured to apply a driving force along the Y axis to the first inclined surface 202 through the second inclined surface 5101 to press the first body portion 21 against the first elastic member 30 along the X axis, thereby disengaging the first locking portion 22 from the second locking portion 41 along the X axis.

It should be noted that the first inclined surface 202 is formed on the first clearance groove 201 along the X axis near the inner side wall of the first elastic member 30, and the second inclined surface 5101 is formed on one side of the wedge-shaped block 51 along the X axis facing the first inclined surface 202; based on this, when the wedge-shaped block 51 sequentially penetrates through the second clearance groove 101 and the first clearance groove 201 and moves along the Y axis, the second inclined surface 5101 can be abutted against the first inclined surface 202 along the Y axis and apply a driving force along the Y axis to the first inclined surface 202, and the first inclined surface 202 and the second inclined surface 5101 are arranged so that the driving force along the Y axis of the wedge-shaped block 51 is converted into an abutting force along the X axis, so that the first main body portion 21 and the first locking portion 22 move away from the second locking portion 41 along the X axis together, at this time, the first main body portion 21 presses the first elastic member 30 along the X axis, and the first locking portion 22 moves away from the second locking portion 41 along the X axis and disengages from the second locking portion 41, thereby unlocking the first locking portion 22 and the second locking portion 41, that is, unlocking the first connecting member 10 and the second connecting member 40 is realized, as shown in fig. 5. With this arrangement, the wedge block 51 is driven to apply a driving force along the Y axis to the first inclined surface 202 through the second inclined surface 5101, so that the first locking portion 22 is disengaged from the second locking portion 41, and the first connecting member 10 and the second connecting member 40 are unlocked to detach the first connecting member 10 and the second connecting member 40. Moreover, the wedge block 51 sequentially penetrates through the second clearance groove 101 and the first clearance groove 201, and at least part of the wedge block 51 extends out of the first connecting member 10 through the second clearance groove 101, so that a user or a mechanical hand is facilitated to drive the wedge block 51, and the disassembling operation of the first connecting member 10 and the second connecting member 40 is simpler.

Alternatively, when the first elastic member 30 is reset, so that the first main body 21 and the first locking portion 22 perform the reset movement along the X axis, the first main body 21 may apply a pushing force along the X axis to the second inclined surface 5101 through the first inclined surface 202, so that the wedge block 51 performs the reset movement along the Y axis, which facilitates the wedge block 51 to apply a driving force along the Y axis to the first main body 21 next time, so as to facilitate the unlocking operation of the first connecting member 10 and the second connecting member 40 next time.

Optionally, as shown in fig. 3 to 6, the Y axis is set to be a vertical direction, the first inclined surface 202 is disposed downward along the Y axis, and the second inclined surface 5101 is disposed upward along the Y axis, so that the wedge block 51 is pushed upward along the Y axis by an external force, so that the second inclined surface 5101 of the wedge block 51 applies an upward driving force to the first inclined surface 202, and the unlocking of the first connecting member 10 and the second connecting member 40 can be achieved; at this time, after the first connecting member 10 and the second connecting member 40 are detached, the wedge block 51 can move downward along the Y axis under the action of its own gravity or external force, so as to remove the driving force applied by the second inclined surface 5101 to the first inclined surface 202, that is, the driving force applied by the wedge block 51 to the first main body 21, and help the first elastic member 30 to drive the first main body 21 and the first locking portion 22 to move downward along the X axis. Or, the first inclined surface 202 is disposed upward along the Y axis, and the second inclined surface 5101 is disposed downward along the Y axis, so that the wedge block 51 is pulled downward along the Y axis by an external force, and the second inclined surface 5101 of the wedge block 51 can provide a downward driving force to the first inclined surface 202, that is, the first connecting member 10 and the second connecting member 40 can be unlocked.

In one embodiment, referring to fig. 3 to 8, the driving structure 50 further includes a second elastic element 52, and the second elastic element 52 extends along the Y axis; the second elastic member 52 abuts between the first connecting member 10 and the wedge 51 to remove the driving force of the second inclined surface 5101 to the first inclined surface 202 when the reset is performed. Based on this, when the external force on the wedge-shaped block 51 is removed, the second elastic member 52 is reset and pushes against the wedge-shaped block 51 along the Y axis, so that the wedge-shaped block 51 is reset and moves along the Y axis, the second inclined surface 5101 on the wedge-shaped block 51 removes the driving force on the first inclined surface 202, that is, the wedge-shaped block 51 removes the driving force on the first main body 21, which is helpful for the wedge-shaped block 51 to drive the first main body 21 next time, and thus the next unlocking operation of the first connecting member 10 and the second connecting member 40 is facilitated, and the wedge-shaped block 51 does not need to be manually reset; so configured, the unlocking operation of the first and

second connectors

10 and 40 is simplified. And, after first connecting piece 10 and second connecting piece 40 are unpacked apart, and when removing the external force to wedge 51, second elastic component 52 drives wedge 51 along the Y axle and resets and removes, in order to remove the drive power of wedge 51 to first main part 21, at this moment, first elastic component 30 drives first main part along 21X axle and resets and removes, and can provide certain supporting thrust along the X axle for wedge 51, so, wedge 51 can realize more high-efficiently under the effect in the lump of second elastic component 52 and first main part 21 and reset and remove.

After the first connector 10 and the second connector 40 are detached, the wedge block 51 can return to move along the Y axis under the action of the self-gravity and the first main body 21 and the second elastic member 52, so as to remove the pushing force on the first main body 21, which does not mean that the second inclined surface 5101 of the wedge block 51 is separated from the first inclined surface 202, and at this time, the second inclined surface 5101 can be separated from the first inclined surface 202, or can be overlapped with the first inclined surface 202 continuously.

In one embodiment, referring to fig. 7 to 9, the wedge block 51 includes a second main body portion 511 and a wedge portion 512, the wedge portion 512 is disposed at one end of the second main body portion 511 along the Y-axis, and the second elastic member 52 abuts between the first connecting member 10 and the wedge portion 512; a second inclined surface 5101 is formed on the wedge portion 512, and the outer peripheral wall of the second body portion 511 and the inner peripheral wall of the second clearance groove 101 are fitted. Based on this, the second body portion 511 is limited in the second clearance groove 101, so that the second body portion 511 can only move along the Y axis, and the second clearance groove 101 achieves a guiding effect on the second body portion 511, thereby reducing the pushing requirement on the second body portion 511, and further simplifying the unlocking operation of the first connecting piece 10 and the second connecting piece 40.

Here, the volume of the first clearance groove 201 needs to satisfy the following condition based on the limit action of the second clearance groove 101 on the second body 511: when the wedge-shaped block 51 sequentially penetrates through the second clearance groove 101 and the first clearance groove 201 and the second elastic element 52 is in the reset state, clearance spaces are formed between the wedge-shaped part 512 and one of the inner side walls of the first clearance groove 201 along the X axis at intervals; the arrangement is such that during the locking process of the first connector 10 and the second connector 40, the first main body portion 21 will not be interfered by the wedge block 51 when moving in the first connector 10 along the X-axis, which is helpful for the locking operation of the first connector 10 and the second connector 40.

Optionally, as shown in fig. 7 and fig. 8, the wedge block 51 further includes a guiding portion 513, the guiding portion 513 is disposed at an end of the wedge portion 512 facing away from the second main body portion 511, the guiding portion 513 extends along the Y axis and movably penetrates through the first connecting element 10 along the Y axis; this is so arranged that the first connecting member 10 can provide a guiding action to the guide portion 513, thereby achieving a guiding effect when the wedge 51 moves along the Y-axis. And, the second elastic element 52 is a spring, and the spring is sleeved outside the guide part 513, so as to further improve the guiding effect of the wedge block 51 moving along the Y axis.

In an embodiment, referring to fig. 1, fig. 2, fig. 7, fig. 9 and fig. 10, the first connecting member 10 includes an end shell 11 and a side shell 12 disposed on the end shell 11, and the first elastic member 30 abuts between the first main body 21 and the side shell 12 along the X axis; the end housing 11 includes a base plate 111 and two guide plates 112 spaced apart from each other on the base plate 111, the base plate 111 defines a mounting hole 1102 for the second locking portion 41 to enter the first connecting member 10, the two guide plates 112 form a sliding slot 1101 at an interval communicating with the mounting hole 1102, and the first body portion 21 is slidably disposed in the sliding slot 1101 along the X-axis.

The sliding groove 1101 extends along the X axis, and the assembly hole 1102 penetrates through the substrate 111 along the Y axis; the second lock portion 41 enters the first connecting member 10 through the fitting hole 1102.

Based on this, the first main body 21 can be slidably disposed in the sliding slot 1101 formed by the two guide plates 112 along the X axis, which helps to improve the guiding effect and stability when the first main body 21 moves, thereby helping to improve the reliability of the attaching and detaching operation of the first connecting member 10 and the second connecting member 40.

In an embodiment, referring to fig. 9 and 10, the guide plate 112 is provided with a position-limiting portion 113, the position-limiting portion 113 and the substrate 111 are spaced apart along the Y-axis, and the first body portion 21 is positioned between the substrate 111 and the position-limiting portion 113 along the Y-axis. Based on this, the sliding groove 1101 is formed by the base plate 111, the two guide plates 112 and the limiting portion 113, which are enclosed together, so that the first main body portion 21 is limited between the base plate 111 and the limiting portion 113 along the Y axis, which contributes to further improving the guiding effect and stability when the first main body portion 21 moves, and further contributes to further improving the reliability of the dismounting operation of the first connecting member 10 and the second connecting member 40.

In one embodiment, referring to fig. 4, 7, 11 and 12, the first locking portion 22 is formed with a first locking surface 2201 and a first guide surface 2202 along two opposite sides of the Y axis, the second locking portion 41 is formed with a second guide surface 4102 and a second locking surface 4101 along two opposite sides of the Y axis, the first locking surface 2201 and the second locking surface 4101 are matched, and the first guide surface 2202 and the second guide surface 4102 are matched; the second lock portion 41 is configured to be able to apply an urging force along the Y axis to the first guide surface 2202 by the second guide surface 4102 to move the first main body portion 21 along the X axis, and is also configured to be able to be locked along the Y axis by the first lock surface 2201 and the second lock surface 4101.

Based on this, when the second locking portion 41 is pushed into the first connecting member 10 along the Y axis, the second locking portion 41 applies a pushing force along the Y axis to the first guide surface 2202 through the second guide surface 4102, so that the pushing force along the Y axis of the second locking portion 41 is converted into a pushing force along the X axis, so that the first locking portion 22 and the first main body portion 21 are moved together along the X axis away from the second locking portion 41, and the first main body portion 21 presses the first elastic member 30 along the X axis; when the second locking portion 41 continues to move along the Y axis in the first connector 10 until the second locking portion 41 disengages from the first locking portion 22, which indicates that the second locking portion 41 has removed the pushing force on the first locking portion 22, at this time, the first elastic member 30 is reset, so that the first main body 21 and the first locking portion 22 are reset and move along the X axis together under the action of the first elastic member 30, and when the first locking portion 22 moves along the X axis until the first locking surface 2201 is located on one side of the second locking surface 4101 along the Y axis, the first locking portion 22 abuts against the second locking surface 4101 of the second locking portion 41 along the Y axis through the first locking surface 2201, so that the first locking portion 22 and the second locking portion 41 are locked, that is, the first connector 10 and the second connector 40 are locked. With this arrangement, the first and

second lock portions

22 and 41 have a very simple structure, and the locking operation of the first and second connecting

members

10 and 40 can be quickly performed.

Optionally, the first locking portion 22 is further formed with a fourth guide surface 2203, the fourth guide surface 2203 being located between the first guide surface 2202 and the first locking surface 2201; accordingly, the second locking portion 41 is further formed with a fifth guide surface 4103, and the fifth guide surface 4103 is positioned between the second guide surface 4102 and the second locking surface 4101. Based on this, when the second locking portion 41 is pushed into the first connector 10 along the Y axis, the second locking portion 41 applies an abutting force along the Y axis to the first guide surface 2202 by the second guide surface 4102, and when the second locking portion 41 moves along the Y axis until the second guide surface 4102 is separated from the first guide surface 2202, the fifth guide surface 4103 moves relative to the fourth guide surface 2203, so that a guide effect of the movement of the second locking portion 41 along the Y axis is achieved; when the second locking portion 41 moves to the point where the fifth guide surface 4103 is separated from the fourth guide surface 2203, the second locking portion 41 is completely separated from the first locking portion 22, and thus the second locking portion 41 has removed the pushing force on the first locking portion 22, and at this time, the first elastic member 30 is reset, so that the first locking surface 2201 of the first locking portion 22 can move to the side of the second locking surface 4101 of the second locking portion 41 along the Y axis, and the first locking portion 22 can be locked with the second locking portion 41 on the Y axis by the first locking surface 2201 and the second locking surface 4101. Of course, according to actual usage requirements, when the fifth guide surface 4103 moves relative to the fourth guide surface 2203, the second locking portion 41 can also push the fourth guide surface 2203 along the Y axis by the fifth guide surface 4103, so that the pushing operation of the first locking portion 22 is continued.

The first locking surface 2201, the first guide surface 2202, the second locking surface 4101 and the second guide surface 4102 may be inclined surfaces, or may be curved surfaces; the fourth guide surface 2203 and the fifth guide surface 4103 may be selected from a slope, a flat surface, and a curved surface.

Alternatively, the inner side wall of the fitting hole 1102 has a third guide surface 1103, and the third guide surface 1103 and the second guide surface 4102 are matched, so that when the second locking portion 41 enters the first connector 10 through the fitting hole 1102, the second locking portion 41 can slide relative to the third guide surface 1103 by the second guide surface 4102, and thus, a guiding effect of the second locking portion 41 entering the first connector 10 is achieved, which helps to simplify the locking operation of the first connector 10 and the second connector 40.

With such an arrangement, when the second locking portion 41 enters the first connecting member 10 to form a Y-axis limit with the first locking portion 22, the buffer assembly 60 elastically abuts against the third main body 42 and/or the second locking portion 41 to provide a certain pre-tightening force to the third main body 42 and/or the second locking portion 41, which is helpful for improving the limit strength of the first locking portion 22 and the second locking portion 41, so as to be helpful for improving the firmness of the locking of the first connecting member 10 and the second connecting member 40.

Optionally, the first connecting member 10 further includes a top cover 13, the top cover 13 is disposed on a side of the side shell 12 facing away from the end shell 11 along the Y axis, the buffer assembly 60 is disposed on the top cover 13 and faces the assembly hole 1102 along the Y axis, and when the second locking portion 41 enters the first connecting member 10 through the assembly hole 1102, the buffer assembly 60 elastically abuts against the second locking portion 41 along the Y axis, which helps to improve the locking firmness of the first locking portion 22 and the second locking portion 41.

Optionally, a limiting sleeve 131 is disposed on a side of the top cover 13 facing the end cover, and the buffering assembly 60 is disposed in the limiting sleeve 131, so that the limiting sleeve 131 can limit the buffering assembly 60, which helps to achieve guidance of a pre-tightening force provided by the buffering assembly 60, thereby helping to improve locking firmness of the first locking portion 22 and the second locking portion 41.

In an embodiment, referring to fig. 7 and 13, the buffering assembly 60 includes a guiding rod 61 and a third elastic member 62, the guiding rod 61 is movably disposed through the first connecting member 10 along the Y axis, the third elastic member 62 is elastically abutted between the guiding rod 61 and the first connecting member 10 along the Y axis, and one end of the guiding rod 61 facing the third main body 42 has a guiding slot 6101 for guiding the third main body 42 therein. With this arrangement, when the second locking portion 41 enters the first connecting member 10, at least a portion of the third main body portion 42 is inserted into the guiding groove 6101, so that the damping member 60 can provide a guiding function for the third main body portion 42 on the basis of providing a pre-tightening force to the third main body portion 42 and/or the second locking portion 41, which helps to simplify the locking operation of the second locking portion 41 and the first locking portion 22.
