[0001] This application is a division of a Chinese invention patent with an application date of December 2, 2021, application number 202111463429.0, and name “A tray 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.

[0010] In this solution, by providing the first elastic member, the mounting portion can be connected to the fixed portion in a floating manner, so that the mounting portion can drive the tray to fine-tune the position in the battery pack disassembly direction within a certain floating space, thereby improving the adaptability of the tray mounting mechanism and the tray, facilitating the disassembly mechanism to align the fasteners, and improving the battery pack loading and unloading efficiency. In addition, the floating in the battery pack disassembly direction can prevent the protruding parts on the tray from rigidly colliding with the electric vehicle due to excessive rise of the tray, thereby extending the service life of the tray.

For example, a shell with matching shape is provided outside the sleeve body, which can prevent the first elastic member from being skewed during the floating process. In addition, the sleeve body can protect the first elastic member from being corroded by the environment and increase the service life. There is a gap of a preset distance between the lower end surface of the sleeve body and the fixing part, which can allow the first elastic member to expand and contract, so as to provide space for the mounting part to move in a direction parallel to the disassembly and assembly direction of the battery pack and limit the floating stroke of the mounting part.

The fixing base is used to fix the fixing part on the battery replacement device on one hand, and is used to connect the first elastic member to achieve floating along the first direction on the other hand. By setting the second elastic component, the mounting part can float relative to the shell in a direction perpendicular to the first direction, so that the mounting part can drive the tray to fine-tune the position on the plane perpendicular to the first direction within a certain floating space, thereby improving the adaptability of the tray mounting mechanism and the tray.

[0090] Pallet 202 DETAILED DESCRIPTION

[0091] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0092] This embodiment discloses a tray installation mechanism 100. Figure 1-8 As shown, the tray installation mechanism 100 is applied to a battery swap station, and the tray 202 is used to carry a battery pack. The tray installation mechanism 100 includes a mounting portion 10, a fixing portion 20, and a first elastic member 30. The mounting portion 10 is used to install the tray 202, and the first elastic member 30 is arranged between the mounting portion 10 and the fixing portion 20; the first elastic member 30 is elastically deformed along a first direction so that the mounting portion 10 moves relative to the fixing portion 20 along the first direction; wherein the first direction is parallel to the disassembly direction of the battery pack.

[0093] By providing the first elastic member 30, the mounting portion 10 can be connected to the fixing portion 20 in a floating manner, so that 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, thereby improving the adaptability of the tray mounting mechanism 100 and the tray 202, facilitating the disassembly mechanism to align the fasteners, and improving the battery pack loading and unloading efficiency. In addition, the floating in the battery pack disassembly direction can prevent the tray 202 from rising excessively, resulting in a rigid collision between the protruding parts on the tray 202 and the electric vehicle, thereby extending the service life of the tray 202.

[0094] 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 direction is the vertical direction. In other alternative embodiments, the disassembly direction of the battery pack may also be other directions, such as a direction extending in a horizontal plane or a direction having an angle with the horizontal plane.

[0095] The mounting portion 10 may include a mounting seat 11 and a first connecting member 12. The mounting seat 11 is used to mount the tray 202. One end of the first connecting member 12 is connected to the mounting seat 11, and the other end of the first connecting member 12 is connected to the first elastic member 30. The mounting seat 11 is connected to the first elastic member 30 through the first connecting member 12. This arrangement increases the area where the mounting portion 10 can be connected to the first elastic member 30 or other components. For example, when there is a floating requirement in other directions, the elastic members in other directions can be directly connected to the first connecting member 12 to avoid the first elastic member 30 or other components interfering with the connection between the mounting seat 11 and the tray 202.

[0096] The mounting seat 11 includes a tray mounting end surface 111 and an extension block 112 connected up and down. The tray mounting end surface 111 is provided with a first assembly hole 113. The mounting seat 11 is threadedly connected to the tray 202 through the first assembly hole 113. The first connecting member 12 is connected to the extension block 112. The cross-sectional area of ​​the extension block 112 can be set to be smaller than the cross-sectional area of ​​the tray mounting end surface 111, so as to reduce the size of the entire tray mounting mechanism 100 and reduce the cost.

[0097] 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. The sleeve body 121 is sleeved on part of the first elastic member 30. When the first elastic member 30 does not undergo elastic deformation, there is a gap of a preset distance between the fixing portion 20 and the lower end surface of the sleeve body 121. The preset distance may be a distance pre-set according to actual floating amount requirements. The first connecting member 12 is arranged in the form of a sleeve. The first elastic member 30 is connected to the mounting seat 11 through the sleeve end cover 122. In the present embodiment, one end of the first elastic member 30 directly abuts against the sleeve end cover 122 to facilitate the installation and replacement of the first elastic member 30. In other optional embodiments, the first elastic member 30 may also be fixedly connected to the sleeve end cover 122 by gluing or clamping. The sleeve body 121 is convenient for cooperating with other components. For example, a shell with matching shape can be provided outside the sleeve body 121 to prevent the first elastic member 30 from being skewed during floating. In addition, the sleeve body 121 can protect the first elastic member 30 from being corroded by the environment and increase its service life.

[0098] The sleeve end cover 122 is provided with a second assembly hole 123 , and the mounting seat 11 is provided with a corresponding third assembly hole 114 . The mounting seat 11 and the first connecting member 12 are threadedly connected via the second assembly hole 123 and the third assembly hole 114 .

[0099] The first elastic member 30 is a spring, and the two ends of the first elastic member 30 are respectively in contact with the sleeve end cover 122 and the fixing portion 20. In this embodiment, a spring is used as the first elastic member 30, which has a simple and reliable structure and low cost. In other optional embodiments, other components such as rubber members can also be used as the first elastic member 30.

[0100] The mounting portion 10 further includes a guide portion 13, which is disposed around the outer side of the first connecting member 12; wherein the inner wall surface of the guide portion 13 matches the outer wall surface of the sleeve body 121, so that the sleeve body 121 can move along the first direction relative to the guide portion 13. The guide portion 13 with matching shape is disposed outside the sleeve body 121, so that the sleeve body 121 moves along the guide portion 13, thereby preventing the movement path of the sleeve body 121 from being skewed during the floating process of the first elastic member 30.

[0101] The mounting portion 10 further includes a bushing 14, which is sandwiched between the guide portion 13 and the first connector 12. The bushing 14 is made of a material with a relatively smooth surface, such as a polymer material such as polytetrafluoroethylene. The friction coefficient of the bushing 14 is smaller than that of the guide portion 13 and the first connector 12. By providing the bushing 14, the friction between the guide portion 13 and the first connector 12 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. Specifically, an outwardly recessed groove 131 is provided on the inner wall of the guide portion 13 to accommodate the bushing 14 to prevent the bushing 14 from falling off during the floating process.

[0102] The tray mounting mechanism 100 further includes a vertical stabilizing member 40, which penetrates the fixing portion 20 and the first elastic member 30 along the first direction to reach the mounting portion 10; wherein the vertical stabilizing member 40 is connected to the mounting portion 10. The vertical stabilizing member 40 is used to connect the mounting portion 10 to the fixing portion 20 to prevent the mounting portion 10 from being separated from the fixing portion 20 along the battery pack disassembly direction during the floating process.

[0103] 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 first 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 arranged outside 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 on the basis of being able to float along the first direction.

[0104] 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 first 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, so that the mounting portion 10 can be prevented from being separated from the fixing portion 20 and the floating of the mounting portion 10 along the first direction can be achieved.

[0105] The fixing part 20 includes a shell 22 and a fixing base 23, the fixing base 23 is arranged below the mounting part 10 along the first direction, and the shell 22 is arranged above the fixing base 23 and is arranged around the outside of the mounting part 10; the tray mounting mechanism 100 also includes a second elastic component 50, the second elastic component 50 is arranged between the mounting part 10 and the shell 22, and the second elastic component 50 undergoes elastic deformation in a direction perpendicular to the first direction so that the mounting part 10 moves relative to the fixing part 20 in a direction perpendicular to the battery pack disassembly and assembly direction.

[0106] The fixing base 23 is used to fix the fixing part 20 on the battery exchange device 200 on one hand, and is used to connect the first elastic member 30 to achieve floating along the first direction on the other hand. By setting the second elastic component 50, the mounting part 10 can float relative to the housing 22 along a direction perpendicular to the first direction, so that the mounting part 10 can drive the tray 202 to fine-tune the position on the plane perpendicular to the first direction within a certain floating space, thereby improving the adaptability of the tray mounting mechanism 100 and the tray 202.

[0107] It should be noted that, in the present embodiment, the fixing portion 20 includes a shell 22 arranged on the outside of the mounting portion 10 to achieve fixation of the second elastic component 50. In other alternative embodiments, the fixing portion 20 may also include a fixed inner shell, the mounting portion 10 is arranged on the outside of the fixed inner shell, and the second elastic component 50 is arranged between the fixed inner shell and the mounting portion 10, which can also achieve fixation of the second elastic component 50.

[0108] The second elastic component 50 may include a second elastic member 51 arranged along the second direction and a third elastic member 52 arranged along the third direction; the second direction is perpendicular to the third direction. The second elastic member 51 and the third elastic member 52 are arranged perpendicular to each other, which optimizes the setting position of the second elastic component 50 on the tray mounting mechanism 100, and facilitates the adaptive adjustment of the mounting portion 10 in all directions within the entire horizontal plane. The second elastic member 51 and the third elastic member 52 are springs, and one end of the second elastic member 51 and the third elastic member 52 are connected to the shell 22, and the other end is connected to the mounting portion 10. Specifically, the number of the second elastic member 51 and the third elastic member 52 are both two, the two second elastic members 51 are arranged opposite to each other, and the two third elastic members 52 are arranged opposite to each other.

[0109] The tray mounting mechanism 100 may further include a second connector 15, the second connector 15 is sandwiched between the first connector 12 and the housing 22, the inner wall surface of the second connector 15 matches the outer wall surface of the first connector 12, and the second elastic component 50 is pressed between the second connector 15 and the housing 22. If the first connector 12 is directly connected to the second elastic component 50, floating in the vertical direction may cause an unstable connection between the second elastic component 50 and the first connector 12, and also cause the first connector 12 to be blocked from moving in the vertical direction. In this embodiment, by providing the second connector 15, the second elastic component 50 can be directly provided on the second connector 15, so as not to interfere with the first connector 12, so that it can float in the vertical direction as needed.

[0110] The second connector 15 includes a connector body 151 and a top cover 152. The top cover 152 is disposed above the connector body 151. A fourth assembly hole 1511 is disposed on the top surface of the connector body 151. A fifth assembly hole 1521 is disposed on the top cover 152. The top cover 152 and the connector body 151 are connected by bolts.

[0111] It should be noted that, in this embodiment, the second connecting member 15 is the above-mentioned guide portion 13, and the two are the same component. In other alternative embodiments, the second connecting member 15 and the guide portion 13 can also be set as two different components, and the second connecting member 15 is set outside the guide portion 13.

[0112] The tray mounting mechanism 100 also includes a pad 60, which is disposed between the first elastic member 30 and the fixed base 23. The upper surface of the pad 60 cooperates with the first elastic member 30, and the lower surface contacts the fixed base 23. The pad 60 is made of a material with a relatively smooth surface, and the friction coefficient of the pad 60 is smaller than that of the first elastic member 30 and the fixed base 23, and is used to reduce the friction between the first elastic member 30 and the fixed base 23 along the direction perpendicular to the battery pack disassembly and assembly, so that the first elastic member 30 moves more smoothly in the direction perpendicular to the battery disassembly and assembly, thereby extending the service life. The fixed base 23 also includes a sliding plate 70, which 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 first elastic member 30 and the fixed base 23.

[0113] 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.
