Description

[0001] This application is a division of a Chinese invention patent with an application date of December 2, 2021, application number 202111460204.X, and name “Pallet installation mechanism, battery exchange equipment and battery exchange station”. Technical Field

[0002] The present application relates to the field of battery replacement, and in particular to a tray installation mechanism, battery replacement equipment and a battery replacement station. Background Art

[0003] The battery packs of existing electric vehicles are generally divided into fixed and replaceable types. Among them, fixed batteries are generally fixed on the vehicle, and the vehicle is directly used as the charging object during charging. The replaceable battery box is generally fixed on the vehicle's bracket through a movable installation. The battery box can be removed to replace or charge the battery box separately. After the replaced battery box is charged, it is reinstalled on the vehicle.

[0004] For replaceable battery installation methods, battery swap stations usually include battery swap equipment for transferring battery packs between battery swap stations and charging compartments, as well as for installing or removing battery packs. Battery swap equipment usually includes a tray for carrying battery packs.

[0005] For replaceable battery packs, they can be installed on the vehicle bracket through fasteners, and the locking device on the vehicle bracket can fix the battery pack. A disassembly and assembly mechanism is usually provided on the tray to complete related operations. The disassembly and assembly mechanism can lock or unlock the fasteners to achieve the installation or removal of the battery pack. At present, during the installation or removal of the battery pack, due to inaccurate positioning of the vehicle or the battery replacement equipment, it is often difficult to align the battery pack with the installation position or the disassembly and assembly mechanism with the fasteners, resulting in difficulties in loading and unloading the battery box. In this case, the installation or removal of the disassembly and assembly mechanism may easily cause damage to the battery pack or the fasteners. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the defect in the prior art that it is difficult to align the disassembly and assembly mechanism with the fasteners, thereby causing the battery box to be difficult to load and unload and easy to be damaged, and to provide a tray installation mechanism, a battery exchange device and a battery exchange station.

[0007] The present invention solves the above technical problems through the following technical solutions:

[0008] A tray mounting mechanism is used in a battery swap station, wherein the tray is used to carry a battery pack, and the tray mounting mechanism includes a mounting portion, a fixing portion, a first elastic component and a second elastic component. The mounting portion is used to mount the tray, and the first elastic component and the second elastic component are both arranged between the mounting portion and the fixing portion. The first elastic component undergoes elastic deformation to enable the mounting portion to move relative to the fixing portion in a direction parallel to a battery pack disassembly and assembly direction; the second elastic component undergoes elastic deformation to enable the mounting portion to move relative to the fixing portion in a direction perpendicular to a battery pack disassembly and assembly direction.

[0009] In this solution, by setting a first elastic component, the mounting portion can drive the tray to fine-tune its position in the direction of battery pack disassembly and assembly within a certain floating space, so that the disassembly and assembly mechanism can align the fasteners in the direction of battery pack disassembly and assembly, thereby improving the loading and unloading efficiency of the battery pack; in addition, the floating in the direction of battery pack disassembly and assembly can prevent the protruding parts on the tray from rising excessively and causing a rigid collision with the electric vehicle, thereby extending the service life of the tray. By setting a second elastic component, the mounting portion can drive the tray to fine-tune its position in a plane perpendicular to the direction of battery pack disassembly and assembly within a certain floating space, so that the disassembly and assembly mechanism can float on a plane perpendicular to the direction of battery pack disassembly and assembly to align the fasteners. The mounting portion of this solution can float in the direction of battery pack disassembly and assembly and in a plane perpendicular to the direction of battery pack disassembly and assembly, thereby improving the adaptability of the tray mounting mechanism and the tray, facilitating the disassembly and assembly mechanism to align the fasteners, improving the loading and unloading efficiency of the battery pack, and reducing component damage.

[0010] Preferably, the mounting portion comprises a mounting seat and a connecting component which are connected to each other, the mounting seat is used to mount the tray, and the connecting component is connected to the first elastic component and the second elastic component.

[0011] In this solution, the first elastic component and the second elastic component can act on the mounting seat by being connected to the connecting component, thereby avoiding interference with the connection between the mounting seat and the tray.

[0012] Preferably, the connecting assembly includes a first connecting member and a second connecting member, and the fixing portion includes a housing and a fixing base;

[0013] The first connecting member, the second connecting member and the shell are sequentially mounted from the inside to the outside, the fixed base is arranged below the first connecting member along the direction parallel to the disassembly and assembly direction of the battery pack, the first connecting member is connected to the first elastic component, and the second connecting member is connected to the second elastic component.

[0014] In this solution, the first elastic component is arranged between the first connector and the fixed base, and the first elastic component is telescopic relative to the fixed base to drive the first connector to float along the battery pack disassembly and assembly direction. The second elastic component is arranged between the second connector and the shell, and the second elastic component is telescopic relative to the shell to drive the second connector to float along the direction perpendicular to the battery pack disassembly and assembly direction. The first connector and the second connector are arranged in a mutually sleeved form. On the one hand, the second connector can transfer the floating along the direction perpendicular to the battery pack disassembly and assembly direction to the first connector, so that only the first connector needs to be connected to the mounting seat to simultaneously realize the floating in the direction parallel to the battery pack disassembly and assembly direction and the floating direction perpendicular to the battery pack disassembly and assembly direction, reduce the parts connected on the mounting seat, and simplify the overall structure; on the other hand, the second connector is arranged on the outside of the first connector, which can prevent the first connector from being skewed during the floating process and maintain the stability of the tray during the floating process. The shell is sleeved on the outside of the second connector, and there is more space for setting the second elastic component between the fixed part and the floating mounting part. The second elastic component can be arranged along the entire circumference, which is conducive to increasing the floating direction on the plane perpendicular to the battery pack disassembly and assembly direction, and further improving the adaptability of the tray mounting mechanism and the tray.

[0015] Preferably, the first connecting member comprises a sleeve body and a sleeve end cover, the sleeve end cover is arranged on one side of the sleeve body, and the sleeve body is sleeved on a part of the first elastic component;

[0016] When the first elastic component does not undergo elastic deformation, a gap of a first preset distance is provided between the upper end surface of the fixed base and the lower end surface of the sleeve body.

[0017] In this solution, the sleeve end cap is used to connect to the mounting seat, and the sleeve body can protect the first elastic component from environmental erosion and increase the service life. The first preset distance gap is used for the first elastic component to expand and contract, so as to provide space for the mounting part to move in a direction parallel to the battery pack disassembly and assembly direction, and to limit the floating travel of the mounting part in a direction parallel to the battery pack disassembly and assembly direction.

[0018] Preferably, when the second elastic component does not undergo elastic deformation, a gap of a second preset distance is provided between the outer wall surface of the second connecting member and the inner wall surface of the shell.

[0019] In this solution, the gap of the second preset distance is used for the expansion and contraction of the second elastic component to provide space for the mounting portion to move in a direction perpendicular to the battery pack disassembly and assembly direction and to limit the floating travel of the mounting portion in a direction perpendicular to the battery pack disassembly and assembly direction.

[0023] In which, the first movable part is movably connected to the outer wall surface of the second connecting part, one end of the second elastic component is connected to the first movable part, and the other end is connected to the second connecting part or the shell; or, the first movable part is movably connected to the inner wall surface of the shell, one end of the second elastic component is connected to the first movable part, and the other end is connected to the second connecting part.

[0024] In this solution, by setting up the first movable part, the second elastic component can move relative to the mounting part along with the first movable part, so that even if the direction of movement of the tray in the plane is inconsistent with the setting direction of the second elastic component, a certain amount of floating can be achieved through the movement of the first movable part, thereby improving the adaptability of the tray mounting mechanism.

[0025] Preferably, a first accommodating groove is provided on the outer wall surface of the second connecting member along the circumferential direction, and the first movable member cooperates with the first accommodating groove and is movable in the first accommodating groove.

[0027] Preferably, the first movable member is a ball, and the ball can roll in the first accommodating groove.

[0028] In this solution, the first movable part is configured in the form of a ball. On the one hand, the second elastic component can receive forces from all directions in a plane perpendicular to the direction of battery pack disassembly and assembly, so that the movement of the tray in all directions within the plane can be adaptive. On the other hand, it is convenient to realize the circumferential movement or rotation of the second connecting part, thereby improving the adaptability of the tray installation mechanism.

[0033] A second accommodating groove is provided at the bottom of the second connecting member along the annular direction. When the third elastic component does not undergo elastic deformation, the second movable member matches with the second accommodating groove.

[0034] In this solution, the second connector is connected to the fixed base through the second movable member, which facilitates the floating between the second connector and the fixed base; by setting the third elastic component, the second connector can float in the direction of battery pack disassembly and assembly, thereby improving the tray installation mechanism and the tray adaptability. The second receiving groove is set, on the one hand, to facilitate the positioning and resetting of the second connector. During installation, the second receiving groove can be aligned with the second movable member to achieve precise positioning. After the battery pack is disassembled and assembled, the installation part is moved by the restoring force of the second elastic component until the second movable member is locked in the second receiving groove to achieve resetting; on the other hand, the second receiving groove is opened along the annular direction, which can allow the second connector to move circumferentially relative to the fixed base during floating, thereby improving the floating alignment effect.

[0035] Preferably, the mounting portion further comprises a guide portion, the guide portion is arranged above the second connecting member along the battery disassembly and assembly direction, and the guide portion is arranged around the outer side of the first connecting member;

[0036] The inner wall surface of the guide portion matches the outer wall surface of the first connecting member, so that the first connecting member can be moved relative to the guide portion along the battery disassembly and assembly direction.

On the other hand, the guide portion is provided above the second connecting member to avoid affecting the floating of the second connecting member.

[0038] Preferably, the tray mounting mechanism further includes a bushing, and the bushing is sandwiched between the first connecting member and the second connecting member.

[0039] In this solution, the bushing can reduce the friction caused by the friction between the first connecting member and the second connecting member, so that the first connecting member can move more smoothly in the direction of battery disassembly and assembly, thereby increasing the service life.

[0040] Preferably, the tray mounting mechanism further comprises a first pad, which is arranged between the first elastic component and the fixed base, wherein the upper surface of the pad cooperates with the first elastic component and the lower surface contacts with the fixed base.

[0041] In this solution, the first pad reduces the friction between the fixed base and the first elastic component, so that the first elastic component can move more smoothly in a direction perpendicular to the battery disassembly and assembly direction, thereby extending the service life.

[0042] Preferably, the fixed base further includes a first sliding plate, and the first sliding plate is embedded in a position of the surface of the fixed base facing the mounting portion corresponding to the first pad.

[0048] In this solution, since the second connecting member pushes the first connecting member to move in a direction perpendicular to the battery pack disassembly and assembly, when the vertical stabilizing member is connected to the first connecting member, the first connecting member can drive the vertical stabilizing member to float in a direction perpendicular to the battery pack disassembly and assembly. The gap of the third preset distance is used to provide space for the vertical stabilizing member to move in a direction perpendicular to the battery pack disassembly and assembly, so as to prevent the vertical stabilizing member from affecting the movement of the mounting portion in a direction perpendicular to the battery pack disassembly and assembly.

[0055] Preferably, the plurality of elastic members are arranged in pairs, and the elastic deformation directions of each pair of elastic members are on the same straight line.

[0056] In this solution, elastic parts in multiple directions are arranged in pairs facing each other, which optimizes the setting position of the elastic parts and facilitates the resetting of the installation part after floating. If one of the elastic parts is damaged, the floating effect of the tray installation mechanism is not affected due to the setting of relative elastic parts.

[0057] Preferably, the first elastic component and the second elastic component are both springs.

[0062] Preferably, there are multiple tray mounting mechanisms, and the multiple tray mounting mechanisms are evenly distributed on the tray.

[0063] In this solution, the tray installation mechanism adopts the above arrangement, which can ensure that the tray floats more smoothly and avoid the tray tilting during the floating process to affect the installation alignment process.

[0117] Pallet 202 DETAILED DESCRIPTION

[0118] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0119] This embodiment discloses a tray installation mechanism 100. Figure 1-8 As shown, the tray mounting mechanism 100 is applied in a battery swap station, and the tray 202 is used to carry the battery pack. The tray mounting mechanism 100 includes a mounting portion 10, a fixing portion 20, a first elastic component 30 and a second elastic component 50. The mounting portion 10 is used to mount the tray 202, and the first elastic component 30 and the second elastic component 50 are both arranged between the mounting portion 10 and the fixing portion 20. The first elastic component 30 undergoes elastic deformation to enable the mounting portion 10 to move relative to the fixing portion 20 in a direction parallel to the battery pack disassembly and assembly direction; the second elastic component 50 undergoes elastic deformation to enable the mounting portion 10 to move relative to the fixing portion 20 in a direction perpendicular to the battery pack disassembly and assembly direction.

[0120] By providing the first elastic component 30, the mounting portion 10 can drive the tray 202 to fine-tune its position in the battery pack disassembly direction within a certain floating space, making it easier for the disassembly mechanism to align the fasteners in the battery pack disassembly direction, thereby improving the efficiency of battery pack loading and unloading; in addition, the floating in the battery pack disassembly direction can prevent the tray 202 from rising too much, causing the protruding parts on the tray 202 to collide rigidly with the electric vehicle, thereby extending the service life of the tray 202. By providing the second elastic component 50, the mounting portion 10 can drive the tray 202 to fine-tune its position on a plane perpendicular to the battery pack disassembly direction within a certain floating space, making it easier for the disassembly mechanism to float on a plane perpendicular to the battery pack disassembly direction to align the fasteners.

[0121] The mounting portion 10 of the present solution can float in the direction of battery pack disassembly and assembly and in a plane perpendicular to the direction of battery pack disassembly and assembly, thereby improving the adaptability of the tray mounting mechanism 100 and the tray 202, facilitating the alignment of the disassembly and assembly mechanism with the fasteners, improving the efficiency of battery pack loading and unloading, and reducing component damage.

[0122] It should be noted that the disassembly direction of the battery pack is determined by the fastening method between the electric vehicle and the battery pack. In this embodiment, the disassembly direction of the battery pack is the vertical direction, that is, the first elastic component 30 can drive the mounting portion 10 to float in the vertical direction, that is, the second elastic component 50 can drive the mounting portion 10 to float in the horizontal plane. In other alternative embodiments, the disassembly direction of the battery pack can also be other directions, such as a direction extending in the horizontal plane or a direction having an angle with the horizontal plane.

[0123] The mounting portion 10 may include a mounting seat 11 and a connecting assembly connected to each other, the mounting seat 11 being used to mount the tray 202, and the connecting assembly being connected to the first elastic assembly 30 and the second elastic assembly 50. The first elastic assembly 30 and the second elastic assembly 50 may act on the mounting seat 11 by being connected to the connecting assembly to avoid interfering with the connection between the mounting seat 11 and the tray 202.

[0124] The connecting component may include a first connecting member 12 and a second connecting member 15, and the fixing part 20 includes a shell 22 and a fixing base 23; the first connecting member 12, the second connecting member 15 and the shell 22 are sequentially arranged from the inside to the outside, and the fixing base 23 is arranged below the first connecting member 12 in a direction parallel to the disassembly and assembly direction of the battery pack. The first connecting member 12 is connected to the first elastic component 30, and the second connecting member 15 is connected to the second elastic component 50.

[0125] The first elastic component 30 is arranged between the first connecting member 12 and the fixed base 23. The first elastic component 30 is retracted relative to the fixed base 23 to drive the first connecting member 12 to float along the battery pack disassembly and assembly direction. The second elastic component 50 is arranged between the second connecting member 15 and the shell 22. The second elastic component 50 is retracted relative to the shell 22 to drive the second connecting member 15 to float along the direction perpendicular to the battery pack disassembly and assembly direction. The first connecting member 12 and the second connecting member 15 are arranged in a mutually nested form. On the one hand, the second connecting member 15 can transfer the floating along the direction perpendicular to the battery pack disassembly and assembly direction to the first connecting member 12, so that only the first connecting member 12 needs to be connected to the mounting seat 11 to simultaneously realize the floating in parallel with the battery pack disassembly and assembly direction and in perpendicular to the battery pack disassembly and assembly direction, thereby reducing the components connected to the mounting seat 11 and simplifying the overall structure. On the other hand, the second connecting member 15 is arranged on the outside of the first connecting member 12, which can prevent the first connecting member 12 from being skewed during the floating process and maintain the stability of the tray 202 during the floating process. The shell 22 is sleeved on the outside of the second connecting member 15, and there is more space between the fixed part 20 and the floating mounting part 10 for setting the second elastic component 50. The second elastic component 50 can be arranged along the entire circumference, which is beneficial to increase the floating direction on the plane perpendicular to the battery pack disassembly and assembly direction, and further improve the adaptability of the tray mounting mechanism 100 and the tray 202.

[0126] The fixed base 23 is arranged below the mounting part 10 along the direction of disassembly and assembly of the battery pack. The fixed base 23 arranged below is used to fix the fixing part 20 on the battery exchange device 200. Compared with the annular shell 22, the contact area between the fixed base 23 and the battery exchange device body 201 is wider, and it is easier and more convenient to realize the connection with the battery exchange device body 201.

[0127] It should be noted that, in this embodiment, the first connector 12, the second connector 15 and the housing 22 are sheathed in sequence from the inside to the outside. In other alternative embodiments, other sheathing methods may also be adopted, and the sheathing order may be freely combined. For example, the housing 22 is set in the center, and the second connector 15 and the first connector 12 are sheathed in sequence from the inside to the outside on the outside. In this way, the second connector 15 can still drive the first connector 12 to float horizontally relative to the housing 22.

[0128] The mounting base 11 may include a mounting end surface 111 of the tray 202 and an extension block 112 connected up and down, and the first connecting member 12 is connected to the extension block 112. The cross-sectional area of ​​the extension block 112 may be set to be smaller than the cross-sectional area of ​​the mounting end surface 111 of the tray 202, so as to reduce the size of the entire tray mounting mechanism 100 and reduce the cost.

[0129] The first connecting member 12 may include a sleeve body 121 and a sleeve end cover 122, the sleeve end cover 122 is arranged on one side of the sleeve body 121, and the sleeve body 121 is sleeved on a portion of the first elastic component 30; when the first elastic component 30 does not undergo elastic deformation, there is a gap of a first preset distance between the upper end surface of the fixed base 23 and the lower end surface of the sleeve body 121.

[0130] The sleeve end cap 122 is used to connect to the mounting seat 11, and the sleeve body 121 can protect the first elastic component 30 from environmental erosion and increase its service life. The gap of the first preset distance is used for the first elastic component 30 to expand and contract, so as to provide space for the mounting portion 10 to move in a direction parallel to the battery pack disassembly and assembly direction, and to limit the floating stroke of the mounting portion 10 in the direction parallel to the battery pack disassembly and assembly direction. Among them, the first preset distance can be a distance pre-set according to the actual floating amount requirement of the mounting portion 10 in the direction parallel to the battery pack disassembly and assembly direction.

[0131] When the second elastic component 50 does not undergo elastic deformation, there is a gap of a second preset distance between the outer wall surface of the second connecting member 15 and the inner wall surface of the housing 22. The gap of the second preset distance is used for the second elastic component 50 to expand and contract, so as to provide space for the mounting portion 10 to move in a direction perpendicular to the battery pack disassembly and assembly, and to limit the floating stroke of the mounting portion 10 in the direction perpendicular to the battery pack disassembly and assembly. The first preset distance can be a distance pre-set according to the actual floating amount requirement of the mounting portion 10 in the direction perpendicular to the battery pack disassembly and assembly.

[0132] The inner wall surface of the shell 22 may be provided with a snap-fit ​​portion 24, and the outer wall surface of the second connector 15 may be provided with a matching portion 25, and the snap-fit ​​portion 24 and the matching portion 25 may slide and match each other in a direction perpendicular to the battery pack disassembly and assembly direction. Through the above arrangement, the second connector 15 can be snapped onto the shell 22, which, on the one hand, facilitates the positioning of the second connector 15 during installation, and on the other hand, limits the second connector 15, so that the second connector 15 can only be displaced perpendicular to the battery pack disassembly and assembly direction relative to the shell 22, thereby preventing the second connector 15 from moving too much vertically relative to the shell 22 and detaching from the fixing portion 20 during the floating process.

[0133] The outer wall surface of the second connecting member 15 may be recessed radially inward to form the matching portion 25, and the inner wall surface of the housing 22 may be protruded radially inward to form the engaging portion 24. In an alternative embodiment, the outer wall surface of the second connecting member 15 may be protruded radially outward to form the matching portion 25, and the inner wall surface of the housing 22 may be recessed radially inward to form the engaging portion 24, as long as the two can cooperate with each other.

[0134] The mounting portion 10 further includes a guide portion 18, which is disposed above the second connector 15 along the battery disassembly direction, and the guide portion 18 is disposed around the outer side of the first connector 12; wherein the inner wall surface of the guide portion 18 matches the outer wall surface of the first connector 12, so that the first connector 12 can move relative to the guide portion 18 along the battery disassembly direction. On the one hand, a guide portion 18 with a matching shape is disposed on the outer side of the first connector 12, which has a guiding and limiting function for the floating of the first connector 12, so that the first connector 12 can move along the guide portion 18, thereby preventing the first elastic component 30 from causing a skew in the moving path of the first connector 12 during the floating process. On the other hand, the guide portion 18 is disposed above the second connector 15 to avoid affecting the floating of the second connector 15.

[0135] The outer edge of the guide portion 18 radially exceeds the second connecting member 15, so that the above-mentioned matching portion 25 is formed between the guide portion 18 and the second connecting member 15. In this solution, the guide portion 18 and the second connecting member 15 are two separate components. In other alternative embodiments, the guide portion 18 and the second connecting member 15 can also be integrally formed.

[0136] The tray mounting mechanism 100 also includes a bushing 14, which is sandwiched between the first connector 12 and the second connector 15. The bushing 14 can reduce the friction caused by the friction between the first connector 12 and the second connector 15, so that the first connector 12 can move more smoothly in the direction of battery disassembly and assembly, thereby increasing the service life. The bushing 14 can be made of a polymer material such as polytetrafluoroethylene. Specifically, an outwardly recessed groove 131 is provided on the inner wall of the second connector 15 for accommodating the bushing 14, and the inner wall surface of the guide portion 18 radially exceeds the inner wall surface of the second connector 15, and limits the bushing 14 in the vertical direction to prevent the bushing 14 from falling off during the floating process.

[0137] The tray mounting mechanism 100 may further include a first movable member 53, wherein the first movable member 53 is movably connected to the outer wall surface of the second connecting member 15, one end of the second elastic component 50 is connected to the first movable member 53, and the other end is connected to the second connecting member 15 or the housing 22; or, the first movable member 53 is movably connected to the inner wall surface of the housing 22, one end of the second elastic component 50 is connected to the first movable member 53, and the other end is connected to the second connecting member 15. By providing the first movable member 53, the second elastic component 50 can move relative to the mounting portion 10 with the first movable member 53, so that even if the direction in which the tray 202 moves in the plane is inconsistent with the setting direction of the second elastic component 50, a certain amount of floating can be achieved through the movement of the first movable member 53, thereby improving the adaptability of the tray mounting mechanism 100.

[0138] A first receiving groove 16 is circumferentially provided on the outer wall surface of the second connecting member 15, and the first movable member 53 cooperates with the first receiving groove 16 and is movable in the first receiving groove 16. By providing the circumferentially extending first receiving groove 16, the second connecting member 15 can move or rotate circumferentially during the floating process, thereby improving the adaptability of the tray installation mechanism 100.

[0139] The first movable member 53 is a ball bearing, which can roll in the first receiving groove 16. The first movable member 53 is set in the form of a ball bearing. On the one hand, the second elastic component 50 can receive forces from various directions in a plane perpendicular to the battery pack disassembly and assembly direction, so that the movement of the tray 202 in various directions in the plane can be adaptive. On the other hand, it is convenient to realize the movement or rotation of the second connecting member 15 in the circumferential direction, thereby improving the adaptability of the tray installation mechanism 100.

[0140] A first mounting hole 26 is provided on the inner wall surface of the housing 22, and a portion of the first elastic component 30 is embedded in the first mounting hole 26; a threaded hole is provided on the housing 22, and a top screw 54 is provided in the threaded hole, and the threaded hole and the top screw 54 form the first mounting hole 26, and one end of the first elastic component 30 abuts against the top screw 54, and the other end abuts against the first movable member 53. The top screw 54 is used to mount the second elastic component 50 to the housing 22, and has a simple structure and is easy to install. The position of the top screw 54 in the threaded hole can be adjusted by rotating the thread to change the depth of the first elastic component 30 embedded in the first mounting hole 26, thereby adjusting the elastic deformation stroke of the first elastic component 30 and adjusting the elastic force of the first elastic component 30.

[0141] In this embodiment, the first movable member 53, the first elastic component 30 and the top screw 54 are separate single parts, and the first elastic component 30 is in contact with the first movable member 53 and the top screw 54, so as to facilitate the installation and replacement of the first elastic component 30. In other alternative embodiments, the first elastic component 30 can also be connected to the first movable member 53 and the top screw 54 by gluing or clamping, and the first movable member 53 and the first elastic component 30 can also directly adopt an integral spring plunger.

[0142] The tray mounting mechanism 100 also includes a second movable member 81 and a third elastic component 80; a second mounting hole 231 is provided on the surface of the fixed base 23 facing the second connecting member 15, and the third elastic component 80 is provided in the second mounting hole 231, one end of the third elastic component 80 is connected to the bottom of the second mounting hole 231, and the other end is movably connected to the mounting portion 10 through the second movable member 81; the third elastic component 80 undergoes elastic deformation, so that the second movable member 81 moves relative to the fixed base 23 along the battery pack disassembly and assembly direction; a second accommodating groove 17 is provided along the annular direction at the bottom of the second connecting member 15, and when the third elastic component 80 does not undergo elastic deformation, the second movable member 81 cooperates with the second accommodating groove 17. The second movable member 81 realizes the movable connection between the second connecting member 15 and the fixed base 23, which facilitates the floating between the second connecting member 15 and the fixed base 23; by providing the third elastic component 80, the second connecting member 15 can float in the battery pack disassembly and assembly direction, thereby improving the adaptability of the tray mounting mechanism 100 and the tray 202.

[0143] By providing the second receiving groove 17, on the one hand, it is convenient to position and reset the second connecting member 15. When installing, the second receiving groove 17 can be aligned with the second movable member 81 to achieve precise positioning. When the battery pack is disassembled, the mounting portion 10 floats relative to the fixed base 23 in a direction perpendicular to the disassembly direction of the battery pack. The floating of the third elastic component 80 in the disassembly direction of the battery pack allows the second movable member 81 to be separated from the second receiving groove 17, so that the second movable member 81 will not hinder the movement of the mounting portion 10. After the battery pack is disassembled, the restoring force of the second elastic component 50 drives the mounting portion 10 to move until the second movable member 81 is stuck in the second receiving groove 17 to achieve reset; on the other hand, the second receiving groove 17 is opened in the circumferential direction, which allows the second connecting member 15 to move circumferentially relative to the fixed base 23 when floating, thereby improving the effect of floating alignment.

[0144] A plurality of second mounting holes 231 are provided on the fixed base 23 at different positions corresponding to the second receiving groove 17, and each second mounting hole 231 is provided with a third elastic component 80 and a second movable member 81. The plurality of second mounting holes 231 can improve the positioning and resetting effect of the mounting portion 10, and improve the floating alignment effect.

[0145] In the present embodiment, the second movable member 81 and the third elastic component 80 are two separate components. In an alternative embodiment, the second movable member 81 and the third elastic component 80 may also be replaced by an integral spring plunger.

[0146] The tray mounting mechanism 100 further includes a first pad 60, which is disposed between the first elastic component 30 and the fixed base 23, wherein the upper surface of the pad matches the first elastic component 30, and the lower surface contacts the fixed base 23. The first pad 60 is used to reduce the friction between the first elastic component 30 and the fixed base 23.

[0147] The fixed base 23 further includes a first sliding plate 70, which is embedded in a position on the surface of the fixed base 23 facing the mounting portion 10 corresponding to the first pad 60. The first sliding plate 70 is used to cooperate with the first pad 60 to further reduce the friction between the first elastic component 30 and the fixed base 23. The first pad 60 and the first sliding plate 70 can be made of a polymer material such as polytetrafluoroethylene.

[0148] The tray mounting mechanism 100 also includes a vertical stabilizing member 40. A first through hole 21 is provided on the fixed base 23. The vertical stabilizing member 40 passes through the first through hole 21 of the fixed base 23 and the first elastic component 30 along the disassembly and assembly direction of the battery pack to reach the mounting portion 10; wherein, the vertical stabilizing member 40 is connected to the mounting portion 10, and the first through hole 21 is provided for the vertical stabilizing member 40 to pass through. Specifically, the bolt is connected to the sleeve end cover 122 of the first connecting member 12. The vertical stabilizing member 40 is used to connect the first connecting member 12 to the fixed base 23 to prevent the first connecting member 12 from detaching from the fixed base 23 during the floating process. The vertical stabilizing member 40 is a bolt, and the vertical stabilizing member 40 is threadedly connected to the first connecting member 12; when the second elastic component 50 does not undergo elastic deformation, there is a gap of a third preset distance between the vertical stabilizing member 40 and the edge of the first through hole 21.

[0149] Since the second connecting member 15 pushes the first connecting member 12 to move in a direction perpendicular to the battery pack disassembly and assembly, the first connecting member 12 can drive the vertical stabilizing member 40 to float in a direction perpendicular to the battery pack disassembly and assembly when the vertical stabilizing member 40 is connected to the first connecting member 12. The third preset distance gap is used to provide space for the vertical stabilizing member 40 to move in a direction perpendicular to the battery pack disassembly and assembly, so as to prevent the vertical stabilizing member 40 from affecting the movement of the fixing portion 20 in a direction perpendicular to the battery pack disassembly and assembly.

[0150] In other alternative embodiments, the vertical stabilizing member 40 may also be connected to the fixing portion 20. Specifically, a bolt is inserted from top to bottom into the sleeve end cover 122, the first elastic component 30 and the fixing base 23, the bolt head is arranged outside the sleeve end cover 122 and maintains a certain gap with the mounting portion 10, and the other end of the bolt is threadedly connected to the fixing base 23, which can also prevent the mounting portion 10 from being separated from the fixing portion 20 and realize the floating of the mounting portion 10.

[0151] The tray mounting mechanism 100 further includes a second pad 61, which is disposed between the vertical stabilizing member 40 and the fixed base 23, the lower surface of the second pad 61 cooperates with the vertical stabilizing member 40, and the upper surface contacts the fixed base 23. The second pad 61 is used to reduce the friction between the fixed base 23 and the vertical stabilizing member 40, so that the vertical stabilizing member 40 moves more smoothly in the direction perpendicular to the battery disassembly and assembly, thereby extending the service life.

[0152] The fixed base 23 further includes a second sliding plate 71, which is embedded in a position on the surface of the fixed base 23 away from the mounting portion 10 and corresponding to the second pad 61. The second sliding plate 71 is used to cooperate with the second pad 61 to further reduce the friction between the fixed base 23 and the vertical stabilizing member 40. The second pad 61 and the second sliding plate 71 can be made of a polymer material such as polytetrafluoroethylene.

[0153] The second elastic component 50 includes a plurality of elastic members, and the plurality of elastic members are arranged between the second connecting member 15 and the shell 22 along different directions so that the mounting portion 10 can move relative to the fixing portion 20 in a plane perpendicular to the direction of disassembly and assembly of the battery pack. By setting a plurality of elastic members in different directions, adaptive adjustment of the second connecting member 15 in multiple directions in a plane perpendicular to the direction of disassembly and assembly of the battery pack is achieved. The plurality of elastic members are arranged in pairs, and the elastic deformation directions of each pair of elastic members are on the same straight line. The elastic members in multiple directions are arranged in pairs facing each other, which optimizes the setting position of the elastic members and facilitates the resetting of the mounting portion 10 after floating. If one of the elastic members is damaged, the floating effect of the tray mounting mechanism 100 is not affected due to the setting of the relative elastic members. The first elastic component 30 and the second elastic component 50 are both springs, which have a simple and reliable structure and low cost. In other optional embodiments, other components such as rubber members can also be used as elastic members.

[0154] Specifically, the second elastic component 50 may include a first elastic member 51 arranged along a first direction and a second elastic member 52 arranged along a second direction, wherein the first direction is perpendicular to the second direction. The first elastic member 51 and the second elastic member 52 are arranged perpendicular to each other, thereby optimizing the arrangement position of the elastic member on the tray mounting mechanism 100, so that the floating effect in each direction is more balanced. The number of the first elastic member 51 and the second elastic member 52 are both two, and the two first elastic members 51 are arranged opposite to each other, and the two second elastic members 52 are arranged opposite to each other.

[0155] In this embodiment, the second elastic component 50 includes two pairs of elastic members perpendicular to each other. In other alternative embodiments, the second elastic component 50 may also include one pair, three pairs, four pairs or more elastic members. In other alternative embodiments, the second elastic component 50 may also include three, five or more elastic members evenly arranged in a plane, and the mounting portion 10 may also float in various directions. Alternatively, the second elastic component 50 may also include only one elastic member, which can also achieve floating in a specified direction.

[0156] A battery swap device 200 includes a battery swap device body 201, a tray 202 for carrying a battery pack, and the above-mentioned tray mounting mechanism 100, wherein the fixing portion 20 of the tray mounting mechanism 100 is disposed on the battery swap device body 201.

[0157] By adopting the above-mentioned tray installation mechanism 100 on the battery exchange device 200, the tray installation mechanism 100 can drive the tray 202 to fine-tune the position on the plane parallel to the battery pack disassembly and assembly direction and perpendicular to the battery pack disassembly and assembly direction within a certain floating space, thereby improving the adaptability of the tray installation mechanism 100 and the tray 202, facilitating the disassembly and assembly mechanism to align the fasteners, improving the loading and unloading efficiency of the battery pack, and reducing component damage.

[0158] The battery exchange device body 201 may include a chassis 2011 and a lifting part 2012. The fixing part 20 is arranged on the lifting part 2012. The lifting part 2012 drives the tray 202 to rise or fall along the battery pack disassembly and assembly direction through the tray installation mechanism 100.

[0159] The lifting part 2012 is a reference for the tray installation mechanism 100 to float. When the lifting part 2012 drives the tray installation mechanism 100 to rise and fall, the tray installation mechanism 100 enables the tray 202 to float, thereby realizing the adaptability of the tray 202 .

[0160] There are multiple tray installation mechanisms 100 , and the multiple tray installation mechanisms are evenly distributed on the tray 202 .

[0161] Specifically, there are at least four tray installation mechanisms 100, and at least four tray installation mechanisms 100 are evenly distributed on the tray 202. The tray installation mechanisms 100 are arranged in the above manner to ensure that the tray 202 floats more stably and prevent the tray 202 from tilting during the floating process and affecting the installation alignment process.

[0162] A battery swap station includes the battery swap device 200 described above.

[0163] By adopting the above-mentioned battery exchange equipment 200 in the battery exchange station, the tray installation mechanism 100 can drive the tray 202 to fine-tune its position in a certain floating space in a direction parallel to and perpendicular to the battery pack disassembly and assembly direction, thereby improving the adaptability of the tray installation mechanism 100 and the tray 202, facilitating the alignment of the disassembly and assembly mechanism with the fasteners, improving the loading and unloading efficiency of the battery pack, and reducing component damage.
