[0002] 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.

[0003] 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.

[0004] 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 present invention solves the above technical problems through the following technical solutions:

[0008] In the present solution, by setting a first elastic component, the mounting portion can be floatingly connected to the fixed portion, driving the tray to fine-tune its position on a plane perpendicular to the disassembly and assembly direction of the battery pack within a certain floating space, thereby improving the adaptability of the tray mounting mechanism and the tray, 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.

[0009] Preferably, the first elastic component includes a plurality of elastic members, and the plurality of elastic members are arranged between the mounting portion and the fixing portion along different directions so that the mounting portion moves relative to the fixing portion in a plane perpendicular to the direction of disassembly and assembly of the battery pack.

There is a gap of a preset distance between the fixing part and the mounting part, which can allow the first elastic component to expand and contract, so as to provide space for the mounting part to move in a direction perpendicular to the disassembly and assembly direction of the battery pack, and limit the floating stroke of the mounting part.

[0037] In this solution, the above arrangement is adopted. On the one hand, it is convenient to position and reset the mounting part. When installing, the second receiving groove is aligned with the second movable part to achieve precise positioning. After the battery pack is disassembled and assembled, the mounting part is driven to move by the restoring force of the first elastic component until the second movable part is locked in the second receiving groove to achieve reset. On the other hand, the second receiving groove is opened along the annular direction, which can allow the mounting part to move circumferentially relative to the fixed base when floating, thereby improving the effect of floating alignment.

[0045] In this solution, the sliding plate is used to reduce the friction force generated by the spring force perpendicular to the direction of battery pack disassembly and assembly.

[0107] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0108] 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, the tray 202 is used to carry the battery pack, the tray mounting mechanism 100 includes a mounting portion 10, a fixing portion 20 and a first elastic component 50, the mounting portion 10 is used to mount the tray 202, the first elastic component 50 is arranged between the mounting portion 10 and the fixing portion 20; the first 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 disassembly and assembly direction of the battery pack.

[0109] By setting the first elastic component 50, the mounting part 10 can be floatingly connected to the fixing part 20, driving the tray 202 to fine-tune its position on a plane perpendicular to the disassembly and assembly direction of the battery pack within a certain floating space, 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 loading and unloading efficiency of the battery pack, and reducing component damage.

[0110] 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, and perpendicular to the disassembly direction of the battery pack refers to any direction in the horizontal plane. In other alternative embodiments, the disassembly direction of the battery pack may also be other directions, such as a direction extending in the horizontal plane or a direction having an angle with the horizontal plane.

[0111] The first elastic component 50 may include a plurality of elastic members, which are arranged between the mounting portion 10 and the fixing portion 20 in different directions so that the mounting portion 10 moves relative to the fixing portion 20 in a plane perpendicular to the direction of disassembly and assembly of the battery pack. By providing a plurality of elastic members in different directions, adaptive adjustment of the mounting portion 10 in multiple directions in a plane perpendicular to the direction of disassembly and assembly of the battery pack is achieved. Specifically, the elastic member may be a spring, which has a simple and reliable structure and low cost. In other optional embodiments, other components such as rubber members may also be used as the elastic member.

[0112] In a preferred embodiment, multiple elastic members can be arranged in pairs, and the elastic deformation direction of each pair of elastic members is 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 on the tray mounting mechanism 100, facilitates the reset of the mounting part 10 after floating, and 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 opposite elastic member.

[0113] Specifically, the first 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.

[0114] In this embodiment, the first elastic component 50 includes two pairs of elastic members perpendicular to each other. In other alternative embodiments, the first elastic component 50 may also include one pair, three pairs, four pairs or more elastic members. In other alternative embodiments, the first 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 first elastic component 50 may also include only one elastic member, which can also achieve floating in a specified direction.

[0115] The mounting portion 10 includes a mounting seat 11 and an extension unit 112 connected up and down. The mounting seat 11 is used to install the tray 202. One end of the extension unit 112 is connected to the lower surface of the mounting seat 11, and the other end extends downward. The first elastic component 50 is arranged between the extension unit 112 and the fixing portion 20. The extension unit 112 squeezes or releases the first elastic component 50 along with the mounting seat 11.

[0116] By providing the extension unit 112, the area where the mounting portion 10 can be connected to the elastic member is increased in the battery pack disassembly direction (vertical direction), and the elastic member does not need to be provided on the mounting seat 11, so that more space is reserved for the mounting seat 11 to be connected to the tray 202, thereby avoiding interference between other components and the tray 202. In addition, the cross-sectional area of ​​the extension unit 112 can be set to be smaller than the cross-sectional area of ​​the mounting seat 11, so as to reduce the size of the entire tray mounting mechanism 100 and reduce the cost.

[0117] The fixing portion 20 is arranged outside the mounting portion 10, wherein, when the first elastic component 50 does not undergo elastic deformation, there is a gap of a first preset distance between the fixing portion 20 and the mounting portion 10, so as to provide space for the mounting portion 10 to move in a direction perpendicular to the battery pack disassembly and assembly direction, and to limit the floating stroke of the mounting portion 10 in the direction perpendicular to the battery pack disassembly and assembly direction. By adopting the form of mutually nesting the fixing portion 20 and the mounting portion 10, there is more space for setting elastic members between the fixing portion 20 and the mounting portion 10, that is, elastic members can be arranged along the entire circumference, which facilitates the setting of elastic members in multiple directions.

[0118] It should be noted that, in the present embodiment, the fixing portion 20 is disposed on the outside of the mounting portion 10 . In other alternative embodiments, the mounting portion 10 may also be disposed on the outside of the fixing portion 20 .

[0119] The tray mounting mechanism 100 further includes a first movable member 53, which is movably connected to the wall surface on one side of the mounting portion 10, and one end of the first elastic component 50 is connected to the first movable member 53, and the other end is connected to the fixed portion 20. By setting the first movable member 53, the first elastic component 50 can move relative to the mounting portion 10 with the first movable member 53, so that even if the direction of movement of the tray 202 in the plane is inconsistent with the setting direction of the elastic member, 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. In an alternative embodiment, the first movable member 53 can also be movably connected to the wall surface on one side of the fixed portion 20, and one end of the first elastic component 50 is connected to the first movable member 53, and the other end is connected to the mounting portion 10.

[0120] The fixing portion 20 is disposed on the outside of the mounting portion 10, and a first receiving groove 16 is disposed on the outer wall surface of the mounting portion 10 along the circumferential direction. 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 mounting portion 10 can move or rotate along the circumferential direction during the floating process, thereby improving the adaptability of the tray mounting mechanism 100.

[0121] The first elastic component 50 is a spring, and the first movable member 53 is a ball, which can roll in the first receiving groove 16. The first movable member 53 is set in the form of a ball. On the one hand, the first elastic component 50 can receive forces from various directions in a plane perpendicular to the battery pack disassembly 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 mounting portion 10 along the circumferential direction, thereby improving the adaptability of the tray mounting mechanism 100.

[0122] The fixing portion 20 is arranged outside the mounting portion 10, and a first mounting hole 26 is arranged on the inner wall surface of the fixing portion 20, and a first elastic component 50 is partially embedded in the first mounting hole 26. The first mounting hole 26 is used to install the first elastic component 50, and the embedded method is adopted to reduce the occupied space, so that the structure of the entire tray mounting mechanism 100 is more compact.

[0123] The fixing part 20 is provided with a threaded hole, in which a top screw 54 is provided, and the threaded hole and the top screw 54 form a first mounting hole 26, and one end of the first elastic component 50 abuts against the top screw 54, and the other end abuts against the ball. The top screw 54 is used to mount the first elastic component 50 to the fixing part 20, and 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 50 embedded in the first mounting hole 26, thereby adjusting the elastic deformation stroke of the first elastic component 50 and adjusting the elastic force of the first elastic component 50.

[0124] In this embodiment, the first movable member 53, the first elastic component 50 and the top screw 54 are separate single parts, and the first elastic component 50 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 50. In other alternative embodiments, the first elastic component 50 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 50 can also directly adopt an integral spring plunger.

[0125] The fixing part 20 is arranged around the outside of the mounting part 10, the inner wall surface of the fixing part 20 is provided with a snap-fitting part 24, and the outer wall surface of the mounting part 10 is provided with a matching part 25, and the snap-fitting part 24 and the matching part 25 are slidably matched in a direction perpendicular to the battery pack disassembly and assembly direction. Through the above arrangement, the mounting part 10 can be snapped on the fixing part 20, which is convenient for installation and positioning, and also prevents the mounting part 10 from moving too much relative to the fixing part 20 in the battery pack disassembly and assembly direction during the floating process and detaching from the fixing part 20.

[0126] The outer wall surface of the mounting portion 10 may be recessed radially inward to form the matching portion 25, and the inner wall surface of the fixing portion 20 may be protruded radially inward to form the engaging portion 24. In an alternative embodiment, the outer wall surface of the mounting portion 10 may be protruded radially outward to form the matching portion 25, and the inner wall surface of the fixing portion 20 may be recessed radially inward to form the engaging portion 24, as long as the two can cooperate with each other.

The shell 22 is arranged in a ring outside the mounting part 10. The shell 22 is arranged above the fixing base 23 and connected to the fixing base 23. The fixing base 23 arranged below is used to fix the fixing part 20 on the battery swapping device 200. Compared with the annular shell 22, the contact area between the fixing base 23 and the battery swapping device body 201 is wider, and it is easier and more convenient to achieve connection with the battery swapping device body 201.

[0128] 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 mounting portion 10, 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 to enable the second movable member 81 to move relative to the fixed base 23 in the direction of battery pack disassembly and assembly. The second movable member 81 is used to realize the movable connection between the mounting portion 10 and the fixed base 23, so as to facilitate the floating between the mounting portion 10 and the fixed base 23; by providing the third elastic component 80, the floating of the fixed portion 20 in the direction of battery pack disassembly and assembly can be realized, thereby improving the adaptability of the tray mounting mechanism 100 and the tray 202.

[0129] The bottom of the mounting portion 10 is provided with a second accommodating groove 17 along the circumferential direction. When the third elastic component 80 does not undergo elastic deformation, the second movable member 81 cooperates with the second accommodating groove 17. With the above arrangement, on the one hand, it is convenient to position and reset the mounting portion 10. When installing, the second accommodating 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 and assembly direction of the battery pack. The floating of the third elastic component 80 in the disassembly and assembly direction of the battery pack allows the second movable member 81 to be separated from the second accommodating 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 first elastic component 50 drives the mounting portion 10 to move until the second movable member 81 is stuck in the second accommodating groove 17 to achieve reset. On the other hand, the second accommodating groove 17 is opened along the circumferential direction, which allows the mounting portion 10 to move circumferentially relative to the fixed base 23 when floating, thereby improving the effect of floating alignment.

[0130] 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.

[0131] 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.

[0132] The tray installation mechanism 100 also includes a fourth elastic member 30, which is disposed between the installation portion 10 and the fixed base 23. The fourth elastic member 30 is elastically deformed along the battery pack disassembly direction so that the installation portion 10 moves along the battery pack disassembly direction relative to the fixed base 23. By providing the fourth elastic member 30, the tray installation mechanism 100 can drive the tray 202 to fine-tune the position in the battery pack disassembly direction within a certain floating space, thereby further improving the self-adaptation of the tray installation mechanism 100 and the tray 202, thereby facilitating the disassembly mechanism to align the fastener in the battery pack disassembly direction, thereby improving the battery pack loading and unloading efficiency.

[0133] Specifically, the mounting portion 10 includes a first connecting member 12 and a second connecting member 15. The first connecting member 12 is connected to the mounting seat 11, and the first connecting member 12 includes 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 fourth elastic member 30; when the fourth elastic member 30 does not undergo elastic deformation, there is a gap of a second preset distance between the fixing portion 20 and the lower end surface of the sleeve body 121. The second preset distance can be a distance pre-set according to the floating amount requirement of the mounting portion in the direction of disassembly and assembly of the battery pack. In this embodiment, the first connecting member 12 is the above-mentioned extension unit 112.

[0134] The second connector 15 is sleeved on the outside of the first connector 12, and the first elastic component 50 is arranged between the second connector 15 and the fixing portion 20; the second connector 15 includes a connector body 151 and a top cover 152, the top cover 152 is arranged above the connector body 151, the outer peripheral wall of the top cover 152 extends outward from the connector body 151, and the outer peripheral wall on the upper side of the connector body 151 is radially recessed inward to form a matching portion 25. Through the above arrangement, the matching portion 25 can be conveniently formed, and the assembly is convenient and the manufacturing cost is low.

[0135] The tray mounting mechanism 100 further includes a pad 60 and a sliding plate 70. The pad 60 is disposed between the fourth elastic member 30 and the fixed base 23, the upper surface of the pad 60 cooperates with the fourth elastic member 30, and the lower surface contacts the fixed base 23. The pad 60 is used to reduce the friction between the fourth elastic member 30 and the fixed base 23. The sliding plate 70 is embedded in the surface of the fixed base 23 facing the mounting portion 10 and the position corresponding to the pad 60. The sliding plate 70 cooperates with the pad 60 to further reduce the friction between the fourth elastic member 30 and the fixed base 23 perpendicular to the direction of battery pack disassembly and assembly, so that the first elastic member 51 moves more smoothly in the direction perpendicular to the battery disassembly and assembly, and prolongs the service life. At least one of the pad 60 and the sliding plate 70 should be made of a material with a relatively smooth surface, and the friction coefficient is smaller than that of the fourth elastic member 30 and the fixed base 23. For example, the pad 60 and / or the sliding plate 70 can be made of a polymer material such as polytetrafluoroethylene.

[0136] The mounting portion 10 further includes a bushing 14, which is sandwiched between the first connector 12 and the second connector 15. By providing the bushing 14, the friction between the first connector 12 and the second connector 15 can be reduced, so that the first connector 12 can move more smoothly in the direction of battery disassembly and assembly, thereby extending 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 to accommodate the bushing 14 and prevent the bushing 14 from falling off during the floating process.

[0137] The tray mounting mechanism 100 also includes a vertical stabilizing member 40, which passes through the fixed base 23 and the fourth elastic member 30 along the direction of battery pack disassembly and assembly to reach the mounting portion 10; wherein the vertical stabilizing member 40 is connected to the mounting portion 10, and the vertical stabilizing member 40 is used to connect the mounting portion 10 to the fixed portion 20 to prevent the mounting portion 10 from detaching from the fixed portion 20 along the direction of battery pack disassembly and assembly during the floating process.

[0138] The vertical stabilizing member 40 is a bolt, and the fixing portion 20 is provided with a first through hole 21. The bolt passes through the fourth elastic member 30 from the first through hole 21 and is threadedly connected to the mounting portion 10. The vertical stabilizing member 40 is in the form of a bolt, which has a simple structure and is easy to install. A certain gap is set between the first through hole 21 and the vertical stabilizing member 40, so that the vertical stabilizing member 40 has a certain margin of motion relative to the fixing portion 20. The bolt head is provided on the outside of the fixing portion 20, and the other end of the bolt is threadedly connected to the mounting portion 10, so as to prevent the mounting portion 10 from being separated from the fixing portion 20 while being able to float along the disassembly direction of the battery pack.

[0139] In other alternative embodiments, the vertical stabilizing member 40 may also be connected to the fixing portion 20. Specifically, a bolt is inserted into the mounting portion 10, the fourth elastic member 30 and the fixing portion 20 from top to bottom, the bolt head is arranged outside the mounting portion 10 and maintains a certain gap with the mounting portion 10, and the other end of the bolt is threadedly connected to the fixing portion 20. Similarly, on the basis of preventing the mounting portion 10 from being separated from the fixing portion 20, the mounting portion 10 can be floated along the disassembly direction of the battery pack.

[0140] In this embodiment, the pad 60 and the sliding plate 70 are also arranged below the fixed base 23. Specifically, the pad 60 and the sliding plate 70 above the fixed base 23 are symmetrically arranged with the pad 60 and the sliding plate 70 above the fixed base 23. The pad 60 and the sliding plate 70 are provided with a second through hole 61 for the vertical stabilizing member 40 to extend therein. One of the pad 60 and the sliding plate 70 is made of a polymer material, or both are made of a polymer material, such as polytetrafluoroethylene.

[0142] 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 perpendicular to the disassembly and assembly direction of the battery pack within a certain floating space, 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.

[0143] The battery exchange device body 201 includes 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 direction through the tray installation mechanism 100. The number of tray installation mechanisms 100 is at least four, and at least four tray installation mechanisms 100 are evenly distributed on the tray 202.
