Description

[0001] This application is a divisional application of Chinese invention patent filed on December 2, 2021, with application number 202111463429.0 and titled "A tray mounting mechanism, a battery swapping device and a battery swapping station". Technical Field

[0002] This application relates to the field of battery swapping, and in particular to a tray mounting mechanism, battery swapping equipment, and battery swapping station. Background Technology

[0003] Currently, electric vehicle battery packs are generally configured in two ways: fixed and swappable. Fixed batteries are typically mounted directly on the vehicle, serving as the charging source. Swappable battery packs, on the other hand, are usually mounted on a bracket on the vehicle using a detachable installation method. The battery pack can be removed for individual replacement or charging. After charging, the removed battery pack is reinstalled on the vehicle.

[0004] For swappable battery installation, battery swapping stations typically include battery swapping equipment to facilitate the transfer of battery packs between swapping stations and charging compartments, as well as the installation or removal of battery packs. The battery swapping equipment typically includes a tray for carrying the battery packs.

[0005] For replaceable battery packs, they can be installed onto a vehicle bracket using fasteners, with locking devices on the bracket securing the battery pack. The bracket typically has a disassembly / removal mechanism to handle these operations. This mechanism can lock or unlock the fasteners, allowing for the installation or removal of the battery pack. Currently, during battery pack installation or removal, inaccurate positioning of the vehicle or battery swapping equipment often leads to difficulties in aligning the battery pack with the installation position or aligning the disassembly / removal mechanism with the fasteners. This results in difficulties in loading and unloading the battery pack, and in such cases, attempting installation or removal using the disassembly / removal mechanism can easily damage the battery pack or fasteners. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the defects in the prior art where the disassembly and assembly mechanism is difficult to align with the fasteners, resulting in difficulties in loading and unloading the battery box and easy damage. The present invention provides a tray mounting mechanism, a battery swapping device, and a battery swapping station.

[0007] The present invention solves the above-mentioned technical problems through the following technical solution:

[0008] A tray mounting mechanism is used in a battery swapping station. The tray is used to carry a battery pack. The tray mounting mechanism includes a mounting part, a fixing part, and a first elastic member. The mounting part is used to mount the tray. The first elastic member is disposed between the mounting part and the fixing part. The first elastic member undergoes elastic deformation along a first direction to cause the mounting part to move relative to the fixing part along the first direction.

[0009] The first direction is parallel to the battery pack assembly / disassembly direction.

[0010] In this design, by incorporating a first elastic element, the mounting section can float and connect to the fixed section. This allows the mounting section to finely adjust the position of the tray within a certain floating space in the battery pack installation / removal direction, improving the adaptability of the tray mounting mechanism and the tray itself. This facilitates alignment of the installation / removal mechanism with the fasteners, increasing the efficiency of battery pack loading and unloading. Furthermore, the floating position in the battery pack installation / removal direction prevents the tray from rising excessively, which could cause protruding parts on the tray to rigidly collide with the electric vehicle, extending the tray's lifespan.

[0011] Preferably, the mounting part includes a mounting base and a first connector, the mounting base being used to mount the tray, one end of the first connector being connected to the mounting base, and the other end of the first connector being connected to the first elastic member.

[0012] In this design, the mounting base is connected to the first elastic member via the first connector. This arrangement increases the area for connection between the mounting part and the first elastic member 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 connector, avoiding interference between the first elastic member or other components and the connection between the mounting base and the tray.

[0013] Preferably, the first connecting member includes a sleeve body and a sleeve end cap, the sleeve end cap being disposed on one side of the sleeve body, and the sleeve body being sleeved on a portion of the first elastic member;

[0014] When the first elastic element does not undergo elastic deformation, there is a gap of a preset distance between the fixing part and the lower end face of the sleeve body.

[0015] In this design, the first connector is configured as a sleeve, and the first elastic element is connected to the mounting base via a sleeve end cap. The sleeve body facilitates cooperation with other components; for example, a matching outer shell can be provided outside the sleeve body to prevent the first elastic element from tilting during floating. Additionally, the sleeve body protects the first elastic element from environmental corrosion, extending its service life. A predetermined gap exists between the lower end face of the sleeve body and the fixing part, allowing the first elastic element to extend and retract, providing space for the mounting part to move parallel to the battery pack installation / removal direction and limiting the floating stroke of the mounting part.

[0016] Preferably, the first elastic element is a spring, and its two ends abut against the sleeve end cap and the fixing part, respectively.

[0017] In this design, a spring is used as the first elastic element, resulting in a simple, reliable structure with low cost.

[0018] Preferably, the mounting portion further includes a guide portion, which is disposed around the outer side of the first connector;

[0019] The inner wall surface of the guide portion matches the outer wall surface of the sleeve body, so that the sleeve body is movable relative to the guide portion in a first direction.

[0020] In this solution, a guide portion with a matching shape is provided outside the sleeve body, so that the sleeve body moves along the guide portion, thereby preventing the movement path of the sleeve body from being skewed during the floating process of the first elastic element.

[0021] Preferably, the mounting portion further includes a bushing sandwiched between the guide portion and the first connector.

[0022] In this solution, by setting a bushing, the friction between the guide and the first connector can be reduced, making the first connector move more smoothly in the battery installation and removal direction and extending its service life.

[0023] Preferably, the pallet mounting mechanism further includes a vertical stabilizing member, which passes through the fixing part and the first elastic member along a first direction to reach the mounting part;

[0024] The vertical stabilizer is connected to the mounting part, or the vertical stabilizer is connected to the fixing part.

[0025] In this design, the vertical stabilizer is used to connect the mounting part to the fixing part, preventing the mounting part from detaching from the fixing part along the battery pack assembly / disassembly direction during the floating process.

[0026] Preferably, the vertical stabilizing member is a bolt, the fixing part is provided with a first through hole, the bolt passes through the first elastic member through the first through hole and is threaded to the mounting part.

[0027] In this design, the vertical stabilizer is a bolt, which is simple in structure and easy to install. The bolt head is located outside the fixed part (not connected to the fixed part), and the other end of the bolt is threaded to the mounting part, thereby achieving floating in the first direction while preventing the mounting part from detaching from the fixed part.

[0028] Preferably, the fixing part includes a housing and a fixing base, the fixing base is disposed below the mounting part along the first direction, and the housing is disposed above the fixing base and surrounds the outside of the mounting part; the tray mounting mechanism further includes a second elastic component, the second elastic component is disposed between the mounting part and the housing, and the second elastic component undergoes elastic deformation along a direction perpendicular to the first direction, so that the mounting part moves relative to the fixing part along a direction perpendicular to the battery pack assembly / disassembly direction.

[0029] In this design, the fixing part adopts the form of a fixed base and a housing. The fixed base serves two purposes: firstly, it secures the fixing part to the battery swapping equipment, and secondly, it connects to the first elastic element to achieve floating along the first direction. By providing a second elastic component, the mounting part can float relative to the housing along a direction perpendicular to the first direction. This allows the mounting part to finely adjust the position of the tray 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.

[0030] Preferably, the second elastic component includes a second elastic member disposed along a second direction and a third elastic member disposed along a third direction; the second direction is perpendicular to the third direction.

[0031] In this design, the second and third elastic elements are arranged perpendicularly to each other, optimizing the position of the second elastic component on the pallet mounting mechanism and facilitating adaptive adjustment of the mounting part in all directions across the entire horizontal plane.

[0032] Preferably, the second elastic element and the third elastic element are springs, and both the second elastic element and the third elastic element are connected to the housing at one end and to the mounting part at the other end.

[0033] Preferably, the pallet mounting mechanism further includes a pad, which is disposed between the first elastic member and the fixed base. The upper surface of the pad cooperates with the first elastic member, and the lower surface contacts the fixed base.

[0034] In this design, the pad reduces friction between the fixed base and the first elastic element, allowing the first elastic element to move more smoothly in the direction perpendicular to the battery installation and removal, thus extending its service life.

[0035] Preferably, the fixed base further includes a sliding plate, which is embedded in the fixed base at a position corresponding to the pad on the surface of the fixed base facing the mounting part.

[0036] In this design, the sliding plate cooperates with the pad to further reduce the friction between the fixed base and the first elastic element.

[0037] A battery swapping device includes a battery swapping device body, a tray for carrying a battery pack, and a tray mounting mechanism as described above, wherein the fixing part of the tray mounting mechanism is disposed on the battery swapping device body.

[0038] In this solution, by adopting the aforementioned tray mounting mechanism on the battery swapping equipment, the tray mounting mechanism can drive the tray to finely adjust its position in the battery pack installation and removal direction within a certain floating space, thereby improving the adaptability of the tray mounting mechanism and the tray, facilitating the alignment of the installation and removal mechanism with the fasteners, improving the battery pack loading and unloading efficiency, and reducing component damage.

[0039] Preferably, the number of pallet mounting mechanisms is at least four, and the at least four pallet mounting mechanisms are evenly distributed on the pallet.

[0040] In this solution, the pallet installation mechanism adopts the above-mentioned arrangement, which can ensure that the pallet floats more smoothly and avoid the pallet tilting during the floating process, thus affecting the installation alignment process.

[0041] Preferably, the battery swapping equipment body includes a chassis and a lifting part, the fixing part is disposed on the lifting part, and the lifting part drives the tray to rise or fall along the battery pack disassembly and assembly direction through the tray mounting mechanism.

[0042] A battery swapping station, comprising the battery swapping equipment described above.

[0043] In this solution, by using the aforementioned battery swapping equipment in the battery swapping station, the pallet installation mechanism can drive the pallet to finely adjust its position in the battery pack installation and removal direction within a certain floating space, thereby improving the adaptability of the pallet installation mechanism and the pallet, facilitating the alignment of the installation and removal mechanism with the fasteners, improving the battery pack loading and unloading efficiency, and reducing component damage.

[0044] The positive and progressive effects of this invention are as follows:

[0045] In this tray mounting mechanism, by incorporating a first elastic element, the mounting section can float and connect to the fixed section. This allows the mounting section to finely adjust the tray's position within a certain floating space in the battery pack installation / removal direction, improving the adaptability of both the tray mounting mechanism and the tray. This facilitates alignment of the installation / removal mechanism with fasteners, increasing the efficiency of battery pack loading and unloading. Furthermore, the floating position in the battery pack installation / removal direction prevents excessive tray lifting, which could lead to rigid collisions between protruding components on the tray and the electric vehicle, extending the tray's lifespan. Accordingly, for battery swapping equipment and stations incorporating this tray mounting mechanism, it offers advantages such as improved tray adaptability, increased battery pack loading / unloading efficiency, and reduced component damage.

[0090] Pallet 202 Detailed Implementation

[0091] The present invention will be described more clearly and completely below with reference to a preferred embodiment and the accompanying drawings.

[0092] This embodiment discloses a pallet mounting mechanism 100. For example... Figure 1-8 As shown, the tray mounting mechanism 100 is used in a battery swapping station, and the tray 202 is used to carry the battery pack. The tray mounting mechanism 100 includes a mounting part 10, a fixing part 20, and a first elastic member 30. The mounting part 10 is used to mount the tray 202, and the first elastic member 30 is disposed between the mounting part 10 and the fixing part 20. The first elastic member 30 undergoes elastic deformation along a first direction, so that the mounting part 10 moves relative to the fixing part 20 along the first direction; wherein, the first direction is parallel to the battery pack mounting / unmounting direction.

[0093] By incorporating the first elastic element 30, the mounting part 10 can be floatingly connected to the fixing part 20. This allows the mounting part 10 to finely adjust the position of the tray 202 within a certain floating space in the battery pack installation / removal direction, improving the adaptability of the tray mounting mechanism 100 and the tray 202. This facilitates alignment of the installation / removal mechanism with the fasteners, improving the efficiency of battery pack loading and unloading. Furthermore, the floating position in the battery pack installation / removal direction prevents the tray 202 from rising excessively, which could cause a rigid collision between protruding parts on the tray 202 and the electric vehicle, extending the service life of the tray 202.

[0094] It should be noted that the direction of battery pack installation and removal is determined by the fastening method between the electric vehicle and the battery pack. In this embodiment, the direction of battery pack installation and removal is vertical, that is, the first direction is vertical. In other alternative embodiments, the direction of battery pack installation and removal can also be other directions, such as a direction extending in the horizontal plane or a direction having an angle with the horizontal plane.

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

[0096] The mounting base 11 includes a pallet mounting end face 111 and an extension block 112 connected vertically. A first mounting hole 113 is provided on the pallet mounting end face 111, and the mounting base 11 and the pallet 202 are threadedly connected through the first mounting hole 113. A first connector 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 pallet mounting end face 111 to reduce the overall size of the pallet mounting mechanism 100 and reduce costs.

[0097] The first connecting member 12 includes a sleeve body 121 and a sleeve end cap 122. The sleeve end cap 122 is disposed on one side of the sleeve body 121, and the sleeve body 121 is sleeved on a portion of the first elastic member 30. When the first elastic member 30 does not undergo elastic deformation, there is a preset distance gap between the fixing part 20 and the lower end face of the sleeve body 121. The preset distance can be a distance pre-set according to the actual floating amount requirement. The first connecting member 12 is configured as a sleeve, and the first elastic member 30 is connected to the mounting base 11 through the sleeve end cap 122. In this embodiment, one end of the first elastic member 30 directly abuts against the sleeve end cap 122 to facilitate the installation and replacement of the first elastic member 30. In other optional embodiments, the first elastic member 30 can also be fixedly connected to the sleeve end cap 122 by means of adhesive or snap-fit. The sleeve body 121 is easy to cooperate with other components. For example, a matching shell can be provided on the outside of the sleeve body 121 to prevent the first elastic element 30 from tilting during the floating process. In addition, the sleeve body 121 can protect the first elastic element 30 from environmental corrosion and extend its service life.

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

[0099] The first elastic element 30 is a spring, and its two ends abut against the sleeve end cap 122 and the fixing part 20, respectively. In this embodiment, a spring is used as the first elastic element 30, which is simple, reliable, and low in cost. In other optional embodiments, other components such as rubber parts can also be used as the first elastic element 30.

[0100] The mounting portion 10 also includes a guide portion 13, which surrounds the outer side of the first connector 12. The inner wall surface of the guide portion 13 matches the outer wall surface of the sleeve body 121, allowing the sleeve body 121 to move relative to the guide portion 13 in a first direction. The shape-matching guide portion 13 is provided outside the sleeve body 121, allowing the sleeve body 121 to move along the guide portion 13, thus preventing the movement path of the sleeve body 121 from becoming skewed during the floating process of the first elastic member 30.

[0101] The mounting part 10 also includes a bushing 14, which is sandwiched between the guide part 13 and the first connector 12. The bushing 14 is made of a relatively smooth material, such as polytetrafluoroethylene or other polymer materials. The friction coefficient of the bushing 14 is lower than that between the guide part 13 and the first connector 12. By providing the bushing 14, the friction between the guide part 13 and the first connector 12 can be reduced, making the movement of the first connector 12 in the battery installation and removal direction smoother and extending its service life. Specifically, the inner wall of the guide part 13 is provided with an outwardly recessed groove 131 to accommodate the bushing 14 and prevent the bushing 14 from falling off during floating.

[0102] The tray mounting mechanism 100 also includes a vertical stabilizer 40, which passes through the fixing part 20 and the first elastic member 30 along a first direction to reach the mounting part 10; wherein, the vertical stabilizer 40 is connected to the mounting part 10. The vertical stabilizer 40 is used to connect the mounting part 10 to the fixing part 20 to prevent the mounting part 10 from detaching from the fixing part 20 along the battery pack disassembly and assembly direction during floating.

[0103] The vertical stabilizer 40 is a bolt. The fixing part 20 has a first through hole 21. The bolt passes through the first elastic member 30 through the first through hole 21 and is threaded to the mounting part 10. The vertical stabilizer 40 is in the form of a bolt, which is simple in structure and easy to install. A certain gap is provided between the first through hole 21 and the vertical stabilizer 40, so that the vertical stabilizer 40 has a certain amount of movement relative to the fixing part 20. The bolt head is located on the outside of the fixing part 20, and the other end of the bolt is threaded to the mounting part 10, thereby preventing the mounting part 10 from detaching from the fixing part 20 while enabling floating in the first direction.

[0104] In other alternative embodiments, the vertical stabilizer 40 may be connected to the fixing part 20. Specifically, a bolt is inserted from top to bottom into the mounting part 10, the first elastic member 30, and the fixing part 20. The bolt head is located outside the mounting part 10 and maintains a certain gap with the mounting part 10. The other end of the bolt is threaded to the fixing part 20. Similarly, while preventing the mounting part 10 from detaching from the fixing part 20, the mounting part 10 can float along the first direction.

[0105] The fixing part 20 includes a housing 22 and a fixing base 23. The fixing base 23 is disposed below the mounting part 10 along the first direction, and the housing 22 is disposed above the fixing base 23 and surrounds 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 disposed between the mounting part 10 and the housing 22. The second elastic component 50 undergoes elastic deformation along the 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 fixed base 23 serves two purposes: firstly, it secures the fixing part 20 to the power swapping equipment 200; secondly, it connects the first elastic element 30 to enable floating along the first direction. By providing the second elastic component 50, the mounting part 10 can float relative to the housing 22 along a direction perpendicular to the first direction. This allows the mounting part 10 to drive the tray 202 to finely adjust its 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 this embodiment, the fixing part 20 includes a housing 22 disposed outside the mounting part 10 to fix the second elastic component 50. In other alternative embodiments, the fixing part 20 may also include a fixing inner shell, the mounting part 10 may be arranged around the outside of the fixing inner shell, and the second elastic component 50 may be disposed between the fixing inner shell and the mounting part 10, which can also achieve the fixation of the second elastic component 50.

[0108] The second elastic component 50 may include a second elastic member 51 disposed along a second direction and a third elastic member 52 disposed along a third direction; the second direction is perpendicular to the third direction. The second elastic member 51 and the third elastic member 52 are disposed perpendicular to each other, which optimizes the placement of the second elastic component 50 on the pallet mounting mechanism 100 and facilitates the adaptive adjustment of the mounting part 10 in all directions throughout the horizontal plane. The second elastic member 51 and the third elastic member 52 are springs, and each of the second elastic member 51 and the third elastic member 52 is connected to the housing 22 at one end and to the mounting part 10 at the other end. Specifically, there are two of each of the second elastic member 51 and the third elastic member 52, with the two second elastic members 51 disposed opposite each other and the two third elastic members 52 disposed opposite each other.

[0109] The pallet mounting mechanism 100 may further include a second connector 15, which 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, vertical floating may cause instability in the connection between the second elastic component 50 and the first connector 12, and may also cause the vertical movement of the first connector 12 to be obstructed. In this embodiment, by providing the second connector 15, the second elastic component 50 can be directly mounted on the second connector 15, thereby not interfering with the first connector 12 and allowing it to float vertically as needed.

[0110] The second connector 15 includes a connector body 151 and a top cover 152. The top cover 152 is located above the connector body 151. A fourth mounting hole 1511 is provided on the top surface of the connector body 151, and a fifth mounting hole 1521 is provided 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 connector 15 is the guide portion 13 described above, and the two are the same component. In other alternative embodiments, the second connector 15 and the guide portion 13 may be set as two different components, and the second connector 15 may be disposed on the outside of 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 mates with the first elastic member 30, and the lower surface contacts the fixed base 23. The pad 60 is made of a relatively smooth material, and its coefficient of friction is lower than that between the first elastic member 30 and the fixed base 23. This reduces the friction between the first elastic member 30 and the fixed base 23 along the direction perpendicular to the battery pack installation and removal, making the movement of the first elastic member 30 smoother and extending its 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 part 10 at a position corresponding to the pad 60. The sliding plate 70, in conjunction with the pad 60, further reduces 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 disposed below the fixed base 23. Specifically, the pad 60 and the sliding plate 70 above the fixed base 23 are symmetrically arranged. The pad 60 and the sliding plate 70 are provided with a second through hole 61 for the vertical stabilizer 40 to extend into. One of the pad 60 and the sliding plate 70 is a polymer material, or both may be polymer materials, such as polytetrafluoroethylene (PTFE).

[0114] This embodiment also discloses a battery swapping device 200. For example... Figure 7-8 As shown, the battery swapping equipment 200 includes a battery swapping equipment body 201, a tray 202 for carrying the battery pack, and a tray mounting mechanism 100 as described above. The fixing part 20 of the tray mounting mechanism 100 is disposed on the battery swapping equipment body 201.

[0115] By employing the aforementioned tray mounting mechanism 100 on the battery swapping equipment 200, the tray mounting mechanism 100 can drive the tray 202 to finely adjust its position in the battery pack installation and removal direction within a certain floating space, thereby improving the adaptability of the tray mounting mechanism 100 and the tray 202, facilitating the alignment of the installation and removal mechanism with the fasteners, preventing damage to the battery pack or fasteners, improving the battery pack loading and unloading efficiency, and reducing component damage.

[0116] In a preferred embodiment, the number of pallet mounting mechanisms 100 is at least four, and the at least four pallet mounting mechanisms 100 are evenly distributed on the pallet 202. This arrangement of the pallet mounting mechanisms 100 ensures more stable floating of the pallet 202 and prevents the pallet 202 from tilting during floating, which could affect the installation alignment process.

[0117] The battery swapping equipment body 201 includes a chassis 2011 and a lifting part 2012. The fixing part 20 is installed 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 mounting mechanism 100.

[0118] This embodiment also discloses a battery swapping station, including the battery swapping equipment 200 as described above.
