Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of battery pack replacement equipment, and particularly relates to a battery transfer device and a battery swap station. BACKGROUND

[0002] In the process of quick battery replacement of an electric vehicle, a battery pack to be charged needs to be taken off and placed on a charging rack, and a fully charged battery pack needs to be replaced on the electric vehicle. At this time, a battery transfer device is needed to place the battery pack to be charged taken off by the battery replacement mobile platform into the charging rack, and to take the replacement battery pack off the charging rack and place it on the battery replacement mobile platform. When transferring the battery pack, the battery transfer device needs to take and place the battery pack through a transfer arm, and the working stroke of the transfer arm determines the transfer distance of the battery pack. Early battery swap stations were designed for battery packs with low capacity and small size, and the transfer path of the battery pack was relatively short. With the progress of battery pack manufacturing and the demand for new energy vehicle range, the size of the battery pack is getting larger and larger, and more battery packs need to be replaced and charged, and the width of the charging rack is also getting wider, so the transfer arm needs to provide a larger transfer stroke to take and place the battery pack, which makes the battery transfer device unable to adapt to the transfer stroke requirement of the battery pack, thereby making the battery swap station unable to meet the battery replacement demand of the battery replacement vehicle with large capacity battery pack. CONTENT OF THE UTILITY MODEL

[0003] The application provides a battery transfer device and a battery swap station to solve the technical problem of difficulty in battery replacement caused by insufficient battery pack transfer stroke of the traditional battery transfer device.

[0004] The technical scheme adopted by the application is as follows:

[0005] A battery transfer device, comprising a supporting frame and a transfer arm arranged on the supporting frame, the transfer arm being used to extend and retract relative to the supporting frame to transfer a battery pack, and further comprising a lifting mechanism mounted on the supporting frame, a supporting tray being arranged on the top of the lifting mechanism, and a butt column being arranged on the bottom of the battery transfer device, the supporting frame driving the lifting mechanism to move downward, and the lifting mechanism driving the supporting tray to move upward relative to the supporting frame under the action of the butt column, so as to separate the battery pack from the transfer arm.

[0006] The battery transfer equipment of the present application is provided with a lifting device. During the transfer process of the battery pack, when the stroke of the transfer arm is not enough to send the battery pack to the preset position, the transfer arm can first transport the battery pack for a partial stroke. When the transfer arm reaches the maximum stroke and cannot continue to transport the battery pack, the transfer arm and the lifting mechanism are driven downward by the support frame until the lifting mechanism abuts against the abutting column. With the continuous downward movement of the support frame, the support tray is continuously moved upward relative to the transfer arm under the action of the lifting mechanism until the battery pack is lifted to realize the separation of the battery pack and the transfer arm. At this time, the transfer arm is retracted, and the transfer arm has a certain conveying stroke to transfer the battery pack. That is, the lifting mechanism and the support tray of the present application can increase the conveying stroke of the transfer arm, realize the applicability of the transfer arm to battery packs with different conveying stroke requirements, and meet the battery replacement needs of battery replacement vehicles with different battery pack sizes.

[0007] The battery transfer equipment described in the present application further comprises the following additional technical features:

[0008] In the state that the battery pack is separated from the transfer arm, the lifting mechanism is driven upward by the support frame, and the support tray is driven downward relative to the support frame under the action of gravity to make the battery pack contact the transfer arm.

[0009] When the battery pack is separated from the transfer arm under the support action of the support tray, and after the transfer arm completes partial retraction, the lifting mechanism and the transfer arm can be driven upward by the support frame. The relative position between the lifting mechanism and the transfer arm changes continuously with the upward movement of the support frame. When the lifting mechanism is separated from the abutting column under the driving of the support frame, the transfer arm is already above the support tray, realizing the re-carrying of the transfer arm to the battery pack. In this way, the transfer arm can further transport the battery pack.

[0010] The lifting mechanism comprises a driving column above the abutting column, and a driven column connected to the driving column through a linkage. When the driving column moves relative to the support frame under the abutting action of the abutting column, the driven column is driven to move synchronously through the linkage.

[0011] During the downward movement of the lifting mechanism, the driving column lifts the support tray upward under the abutting action of the abutting column, and the relative position between the driving column and the support frame changes, so that the driven column is lifted upward together through the linkage, and the support tray moves steadily upward relative to the support frame under the lifting force of the driving column and the driven column, improving the stress stability of the support tray, preventing the eccentric force caused by the battery pack not falling to the center of the support tray from affecting the stability of the support tray, and improving the carrying stability of the support tray to the battery pack, providing stability guarantee for the transfer work of the battery pack.

[0012] The linkage comprises a first rotating rod, a second rotating rod, a first support member hinged to the first rotating rod, and a second support member hinged to the second rotating rod, the driving column, the first rotating rod, the second rotating rod, and the driven column being hinged in sequence; with movement of the driving column in the vertical direction, the first rotating rod rotates under the support of the first support member and drives the second rotating rod to rotate under the support of the second support member, thereby driving the driven column to move synchronously.

[0013] During the lowering of the support frame, when the driving column abuts against the abutting column, the driving column moves upward relative to the support frame under the abutting action of the abutting column and drives the first rotating rod to rotate about the first support member as a fulcrum, with the rotation of the first rotating rod, the second rotating rod starts to rotate about the second support member as a fulcrum and drives the driven column connected thereto to move upward, thereby realizing the synchronous upward movement of the driving column and the driven column; the same is true during the upward movement of the support frame, the driving column and the abutting column gradually separate, the driving column gradually moves downward relative to the support frame, and the driven column moves downward synchronously through the rotation of the first rotating rod and the second rotating rod about the first support member and the second support member as fulcrums, thereby realizing the synchronous downward movement of the driving column and the driven column; that is, by providing the first rotating rod, the second rotating rod, the first support member, and the second support member, the consistency of the upward and downward movement amplitudes of the driven column and the driving column is realized, which provides a guarantee for the stable upward or downward movement of the support tray.

[0014] The first support member and the second support member are both mounted on the support frame.

[0015] The first support member and the second support member are provided on the support frame, which can provide a relatively stable mounting position for the first support member and the second support member, thereby providing a relatively stable rotating fulcrum for the first rotating rod and the second rotating rod; on the other hand, the first support member and the second support member are separated, which facilitates the replacement of different sizes of support trays according to the types and sizes of battery packs required by the battery swap station, thereby improving the adaptability of the battery pack transfer equipment to different sizes and types of battery packs.

[0016] The first support member comprises a first mounting part connected with the support frame and a first support part hinged with the first rotating rod, the first mounting part comprises first positioning plates respectively located at two sides of the support frame, the first positioning plates are provided with first positioning holes in alignment with the support frame, and the first mounting part is connected with the support frame by first fixing members penetrating the first positioning holes; and / or the second support member comprises a second mounting part connected with the support frame and a second support part hinged with the second rotating rod, the second mounting part comprises second positioning plates respectively located at two sides of the support frame, the second positioning plates are provided with second positioning holes in alignment with the support frame, and the second mounting part is connected with the support frame by second fixing members penetrating the second positioning holes.

[0017] The first mounting part is connected with the support frame by penetrating the first positioning plates and the first fixing members of the support frame in sequence, so that the connection stability of the first support member and the support frame is improved, and the force borne by the first support member when supporting the rotation of the first rotating rod is transmitted to the support frame through the first positioning plates, so that the probability of stress concentration at the connection between the first mounting part and the support frame is reduced, and the stability of the first support member is improved; similarly, the second mounting part is connected with the support frame by penetrating the second positioning plates and the second fixing members of the support frame in sequence, so that the connection stability of the second support member and the support frame is improved, and the force borne by the second support member when supporting the rotation of the second rotating rod is transmitted to the support frame through the second positioning plates, so that the probability of stress concentration at the connection between the second mounting part and the support frame is reduced, and the stability of the second support member is improved.

[0018] The first connecting lug plate is provided on the driving column, the first connecting lug plate is provided with a first rotating hole, the first rotating rod is provided with a first matching hole, the first rotating rod and the first connecting lug plate are hinged by a first rotating shaft inserted into the first matching hole and the first rotating hole in sequence; the second connecting lug plate is provided on the driven column, the second connecting lug plate is provided with a second rotating hole, the second rotating rod is provided with a second matching hole, the second rotating rod and the second connecting lug plate are hinged by a second rotating shaft inserted into the second matching hole and the second rotating hole in sequence; one of the first rotating rod and the second rotating rod is provided with a third rotating hole, and the other one is provided with a third matching hole, the first rotating rod and the second rotating rod are hinged by a third rotating shaft inserted into the third matching hole and the third rotating hole in sequence.

[0019] The first connecting lug plate is arranged on the driving column, and the first rotating shaft is used to realize the hinging of the first rotating rod and the first connecting lug plate. On the one hand, the hinging difficulty of the first rotating rod and the driving column is reduced. On the other hand, the influence of the hinging point of the first rotating rod and the driving column on the overall structure of the driving column is reduced, so that the driving column can stably support the supporting plate. Similarly, the second connecting lug plate is arranged on the driven column, and the second rotating shaft is used to realize the hinging of the second rotating rod and the second connecting lug plate. On the one hand, the hinging difficulty of the second rotating rod and the driven column is reduced. On the other hand, the influence of the hinging point of the second rotating rod and the driven column on the overall structure of the driven column is reduced, so that the driven column can stably support the supporting plate. The third rotating hole and the third matching hole are arranged on the first rotating rod and the second rotating rod respectively, and the third rotating shaft is used to realize the hinging of the first rotating rod and the second rotating rod. The assembly connection of the first rotating rod and the second rotating rod is simple, and the connection stability of the first rotating rod and the second rotating rod is ensured.

[0020] The first rotating hole is a waist-shaped hole extending at an angle with the driving column, so that the first rotating shaft can move along the extension direction of the first rotating hole when the first rotating rod rotates relative to the driving column; and / or the second rotating hole is a waist-shaped hole extending at an angle with the driven column, so that the second rotating shaft can move along the extension direction of the second rotating hole when the second rotating rod rotates relative to the driven column; and / or the third rotating hole is a waist-shaped hole extending along the length direction of the first rotating rod or the second rotating rod, so that the third rotating shaft can move along the extension direction of the third rotating hole when the first rotating rod and the second rotating rod rotate relative to each other.

[0021] The first rotating hole is a waist-shaped hole, which provides a movement space for the first rotating shaft when the first rotating rod rotates relative to the driving column, preventing the first rotating rod from being stuck during rotation. Similarly, the second rotating hole is a waist-shaped hole, which provides a movement space for the second rotating shaft when the second rotating rod rotates relative to the driven column, preventing the second rotating rod from being stuck during rotation. The third rotating hole allows the third rotating shaft to move along the third rotating hole during the relative rotation of the first rotating rod and the second rotating rod, preventing the first rotating rod and the second rotating rod from being stuck during relative rotation.

[0022] The lifting mechanism further comprises a first guide sleeve arranged on the supporting frame, and the first guide sleeve has a first guide cavity inside for guiding the movement of the driving column, and the driving column passes through the first guide cavity; and / or the lifting mechanism further comprises a second guide sleeve arranged on the supporting frame, and the second guide sleeve has a second guide cavity inside for guiding the movement of the driven column, and the driven column passes through the second guide cavity.

[0023] By setting the first guide sleeve, the upward and downward movement of the driving column under the abutting action of the abutting column can be guided, so that the driving column moves along the extension direction of the first guide sleeve, avoiding movement deviation during the movement of the driving column, and helping to improve the stability of the supporting tray in supporting the battery pack. Similarly, by setting the second guide sleeve, the upward and downward movement of the driven column under the action of the connecting member can be guided, so that the driven column moves along the extension direction of the second guide sleeve, avoiding movement deviation during the movement of the driven column, and helping to improve the stability of the supporting tray in supporting the battery pack.

[0024] The number of driven columns is multiple and is distributed along the circumference of the supporting tray.

[0025] The number of driven columns is set to multiple, which can improve the uniformity of the application of the supporting force of the driven column to the supporting tray, and further reduce the probability of the deflection and overturning phenomenon caused by the stress deviation of the supporting tray.

[0026] The supporting tray is square, the number of driven columns is four and is distributed at the inner corners of the supporting tray, and the driving column is located on the connecting line of the two driven columns on the front side of the supporting tray.

[0027] In this way, the support stability of the driven column to the supporting tray is further improved. No matter where the battery pack is located on the supporting tray, when the supporting tray has a deflection tendency in any direction, the driven column can always apply a stable supporting force to the supporting tray to prevent the supporting tray from overturning. By setting the driving column between the connecting lines of the two driven columns on the front side of the supporting tray, the abutting column is located on the front side of the supporting tray, thereby easily avoiding the supporting bracket, which helps to optimize the structural design of the battery transfer equipment.

[0028] The number of transfer arms is two and is arranged at intervals on the supporting bracket, and the supporting tray is located between the transfer arms.

[0029] The number of transfer arms is set to two, which can improve the stability of the transfer arm in supporting the battery pack. By placing the supporting tray between the two transfer arms, the battery pack originally supported by the transfer arm can cover the length direction of the supporting tray when supported by the supporting tray, thereby improving the stability of the supporting tray in supporting the battery pack.

[0030] The application also provides a battery swap station, which comprises a charging rack and the battery transfer equipment as described above.

[0031] The battery swap station of the application has good adaptability to battery packs of different sizes and different transfer mileage requirements, and can better meet the battery swap needs of the battery swap vehicle.

[0032] Due to the adoption of the above technical solutions, the application has the following beneficial effects:

[0033] 1. The battery transfer device of the present application is provided with a lifting device. During the transfer process of the battery pack, when the stroke of the transfer arm is not enough to send the battery pack to the preset position, the transfer arm can first transport the battery pack for a partial stroke. When the transfer arm reaches the maximum stroke and cannot continue to transport the battery pack, the transfer arm is driven downward by the support frame and the lifting mechanism, until the lifting mechanism abuts against the abutting column. With the continuous downward movement of the support frame, the support tray is continuously moved upward relative to the transfer arm under the action of the lifting mechanism, until the battery pack is lifted to realize the separation of the battery pack and the transfer arm. At this time, the transfer arm is retracted, and the transfer arm has a certain conveying stroke to transfer the battery pack. That is, the lifting mechanism and the support tray of the present application can increase the conveying stroke of the transfer arm, realize the applicability of the transfer arm to battery packs with different conveying stroke requirements, and meet the battery replacement needs of battery replacement vehicles with different battery pack sizes.

[0034] 2. As a preferred embodiment of the present application, when the battery pack is separated from the transfer arm under the support of the support tray, and after the transfer arm completes partial retraction, the lifting mechanism and the transfer arm can be driven upward by the support frame. The relative position between the lifting mechanism and the transfer arm changes continuously with the upward movement of the support frame. When the lifting mechanism is separated from the abutting column under the driving of the support frame, the transfer arm is located above the support tray, realizing the re-carrying of the transfer arm to the battery pack. In this way, the transfer arm can further transport the battery pack. BRIEF DESCRIPTION OF DRAWINGS

Moreover, the specific features, structures, materials or characteristics described can be combined in any appropriate manner in any one or more embodiments or examples.

[0061] Embodiment one:

[0062] As shown in Figure 1 , Figure 6 A battery transfer device, comprising a support frame 120 and a transfer arm 130 provided on the support frame 120, the transfer arm 130 being used to extend and retract relative to the support frame 120 to transfer a battery pack, further comprising a lifting mechanism 1 mounted on the support frame 120, the lifting mechanism 1 being provided with a supporting tray 2 at the top, and the battery transfer device being provided with an abutting column at the bottom, the support frame 120 drives the lifting mechanism 1 to move downward, and the lifting mechanism 1 drives the supporting tray 2 to move upward relative to the support frame 120 under the action of the abutting column, so as to separate the battery pack from the transfer arm 130.

[0063] The battery transfer device of the present application is provided with a lifting device. During the transfer process of the battery pack, when the stroke of the transfer arm 130 is not enough to send the battery pack to the preset position, the transfer arm 130 can be used to transport the battery pack for a partial stroke. The preset position can be a charging rack or a battery replacement device in the battery replacement station. The battery transfer device in the battery replacement station is generally used to transfer the battery between the two. When the transfer arm 130 reaches the maximum stroke and cannot continue to transport the battery pack, the transfer arm 130 is lowered with the support frame 120 and the lifting mechanism 1 until the lifting mechanism 1 abuts against the abutting column. With the continuous lowering of the support frame 120, the support tray 2 is continuously lifted relative to the transfer arm 130 under the action of the lifting mechanism 1 until the battery pack is lifted to realize the separation of the battery pack and the transfer arm 130. At this time, the transfer arm 130 is retracted, and the transfer arm 130 has a certain conveying stroke to transfer the battery pack. That is, the lifting mechanism 1 and the support tray 2 of the present application can increase the conveying stroke of the transfer arm 130, realize the applicability of the transfer arm 130 to battery packs with different conveying stroke requirements, and meet the battery replacement needs of battery replacement vehicles with different battery pack sizes.

[0064] As a preferred embodiment under the present embodiment, as shown in Figure 1 In the state that the battery pack is separated from the transfer arm 130, the lifting mechanism 1 is lifted by the support frame 120, and the support tray 2 is lowered by the lifting mechanism 1 under the action of gravity to make the battery pack contact with the transfer arm 130. When the battery pack is separated from the transfer arm 130 under the support of the support tray 2, and the transfer arm 130 completes partial retraction, the lifting mechanism 1 and the transfer arm 130 can be lifted by the support frame 120, and the relative position between the lifting mechanism 1 and the transfer arm 130 changes with the lifting of the support frame 120. When the lifting mechanism 1 is separated from the abutting column under the driving of the support frame 120, the transfer arm 130 is located above the support tray 2, realizing the re-carrying of the battery pack by the transfer arm 130. In this way, the transfer arm 130 can further transport the battery pack.

[0065] As another preferred embodiment under the present embodiment, as shown in Figure 1As shown, the lifting mechanism 1 includes a driving column 11 above the abutting column, and a driven column 12 connected to the driving column 11 through a linkage 13. When the driving column 11 moves relative to the support frame 120 under the abutting action of the abutting column, the driving column 11 drives the driven column 12 to move synchronously through the linkage 13. During the lowering process of the lifting mechanism 1, the driving column 11 is lifted upward to lift the support tray 2 under the abutting action of the abutting column, and the relative position of the driving column 11 and the support frame 120 changes, so that the driven column 12 is driven upward by the linkage 13 to lift the support tray 2, and the support tray 2 moves steadily upward relative to the support frame 120 under the lifting force of the driving column 11 and the driven column 12, which improves the stress stability of the support tray 2, prevents the eccentric force of the battery pack when it is not placed in the center of the support tray 2 from affecting the stability of the support tray 2, and improves the load stability of the support tray 2 to battery pack, thereby providing stability guarantee for the transfer of the battery pack.

[0066] As a preferred example in the present embodiment, as shown in Figure 2 As shown, the linkage 13 includes a first rotating rod 131, a second rotating rod 132, a first support 133 hinged to the first rotating rod 131, and a second support 134 hinged to the second rotating rod 132. The driving column 11, the first rotating rod 131, the second rotating rod 132, and the driven column 12 are hinged in sequence. With the movement of the driving column 11 in the vertical direction, the first rotating rod 131 rotates under the support of the first support 133 and drives the second rotating rod 132 to rotate under the support of the second support 134, thereby driving the driven column 12 to move synchronously.

[0067] During the lowering process of the support frame 120, when the driving column 11 abuts against the abutting column, the driving column 11 moves upward relative to the support frame 120 under the abutting action of the abutting column, and the first rotating rod 131 rotates about the first support 133, and the second rotating rod 132 rotates about the second support 134 to drive the driven column 12 to move upward, thereby realizing the synchronous upward movement of the driving column 11 and the driven column 12. During the upward movement of the support frame 120, the driving column 11 gradually separates from the abutting column, and the driving column 11 gradually moves downward relative to the support frame 120, and the first rotating rod 131 and the second rotating rod 132 rotate about the first support 133 and the second support 134, respectively, to drive the driven column 12 to move downward synchronously, thereby realizing the synchronous downward movement of the driving column 11 and the driven column 12. That is, by arranging the first rotating rod 131, the second rotating rod 132, the first support 133, and the second support 134, the upward and downward movement amplitudes of the driven column 12 and the driving column 11 are consistent, thereby guaranteeing the stable upward and downward movement of the support tray 2.

[0068] The present example does not limit the installation position of the first support 133 and the second support 134, which can adopt any of the following manners:

[0069] Manner one: The first support 133 and the second support 134 are both installed on the support frame 120. The first support 133 and the second support 134 are arranged on the support frame 120, which can provide a relatively stable installation position for the first support 133 and the second support 134, thereby providing a relatively stable rotation fulcrum for the first rotating rod 131 and the second rotating rod 132. In addition, the first support 133 and the second support 134 are separated, which facilitates the replacement of different sizes of support trays 2 according to the type and size of the battery pack, thereby improving the adaptability of the battery pack transfer equipment to different sizes of battery packs.

[0070] The present example does not limit the structure of the first support 133 and the second support 134, which can adopt any of the following schemes:

[0071] Scheme one: As shown in Figure 2 , Figure 3 , the first support 133 includes a first installation part 1331 connected with the support frame 120 and a first support part 1332 hinged with the first rotating rod 131. The first installation part 1331 includes first positioning plates 13311 located on both sides of the support frame 120, respectively. The first positioning plates 13311 are provided with first positioning holes 3 in alignment with the support frame 120, and the connection between the first installation part 1331 and the support frame 120 is realized by the first fixing part 5 penetrating the first positioning holes 3.

[0072] Scheme two: As shown in Figure 2 , Figure 4 , the second support 134 includes a second installation part 1341 connected with the support frame 120 and a second support part 1342 hinged with the second rotating rod 132. The second installation part 1341 includes second positioning plates 13411 located on both sides of the support frame 120, respectively. The second positioning plates 13411 are provided with second positioning holes 4 in alignment with the support frame 120, and the connection between the second installation part 1341 and the support frame 120 is realized by the second fixing part 6 penetrating the second positioning holes 4.

[0074] The connection between the first mounting portion 1331 and the support frame 120 is realized by sequentially penetrating the first positioning plates 13311 and the first fixing members 5 of the support frame 120, which can improve the connection stability of the first support 133 and the support frame 120, and the force borne by the first support 133 when supporting the rotation of the first rotating rod 131 can be transmitted to the support frame 120 through the first positioning plates 13311, thereby reducing the probability of stress concentration at the connection between the first mounting portion 1331 and the support frame 120 and improving the stability of the first support 133; similarly, the connection between the second mounting portion 1341 and the support frame 120 is realized by sequentially penetrating the second positioning plates 13411 and the second fixing members 6 of the support frame 120, which can improve the connection stability of the second support 134 and the support frame 120, and the force borne by the second support 134 when supporting the rotation of the second rotating rod 132 can be transmitted to the support frame 120 through the second positioning plates 13411, thereby reducing the probability of stress concentration at the connection between the second mounting portion 1341 and the support frame 120 and improving the stability of the second support 134.

[0075] Mode two: the first support 133 and the second support 134 are both mounted on the support tray 2. Mounting the first support 133 and the second support 134 on the bottom of the support tray 2 can save the punching and mounting operation on the support frame 120 and help ensure the structural integrity of the support frame 120.

[0076] Preferably, as Figure 2As shown, the driving column 11 is provided with a first connecting lug plate 111, the first connecting lug plate 111 is provided with a first rotating hole 1111, the first rotating rod 131 is provided with a first matching hole, and the first rotating shaft 7 inserted into the first matching hole and the first rotating hole 1111 in sequence realizes the hinging of the first rotating rod 131 and the first connecting lug plate 111; the driven column 12 is provided with a second connecting lug plate 121, the second connecting lug plate 121 is provided with a second rotating hole 1211, the second rotating rod 132 is provided with a second matching hole, and the second rotating shaft 8 inserted into the second matching hole and the second rotating hole 1211 in sequence realizes the hinging of the second rotating rod 132 and the second connecting lug plate 121; one of the first rotating rod 131 and the second rotating rod 132 is provided with a third rotating hole 1311, and the other is provided with a third matching hole 1321, and the third rotating shaft 9 inserted into the third matching hole 1321 and the third rotating hole 1311 in sequence realizes the hinging of the first rotating rod 131 and the second rotating rod 132.

[0077] By setting the first connecting lug plate 111 on the driving column 11 and realizing the hinging of the first rotating rod 131 and the first connecting lug plate 111 through the first rotating shaft 7, on the one hand, the hinging difficulty of the first rotating rod 131 and the driving column 11 is reduced; on the other hand, the influence of the hinging point of the first rotating rod 131 and the driving column 11 on the overall structure of the driving column 11 is reduced, so that the driving column 11 can stably provide support to the supporting tray 2; similarly, by setting the second connecting lug plate 121 on the driven column 12 and realizing the hinging of the second rotating rod 132 and the second connecting lug plate 121 through the second rotating shaft 8, on the one hand, the hinging difficulty of the second rotating rod 132 and the driven column 12 is reduced; on the other hand, the influence of the hinging point of the second rotating rod 132 and the driven column 12 on the overall structure of the driven column 12 is reduced, so that the driven column 12 can stably provide support to the supporting tray 2; and by setting the third rotating hole 1311 and the third matching hole 1321 on the first rotating rod 131 and the second rotating rod 132 respectively and realizing the hinging of the first rotating rod 131 and the second rotating rod 132 through the third rotating shaft, the assembly connection of the first rotating rod 131 and the second rotating rod 132 is relatively simple, and the connection stability of the first rotating rod 131 and the second rotating rod 132 is ensured.

[0078] Further, as shown in the drawings, Figure 2 the first rotating hole 1111 is a waist-shaped hole extending at an angle with the driving column 11, so that the first rotating shaft 7 can move along the extension direction of the first rotating hole 1111 when the first rotating rod 131 rotates relative to the driving column 11; the first rotating hole 1111 is a waist-shaped hole, which provides a movement space for the first rotating shaft 7 when the first rotating rod 131 rotates relative to the driving column 11, preventing the first rotating rod 131 from being stuck during rotation.

[0079] As shown in the drawings,Figure 2 As shown, the second rotating hole 1211 is an oblong hole extending at an angle to the driven post 12, so that the second rotating shaft 8 can move along the extension direction of the second rotating hole 1211 when the second rotating rod 132 rotates relative to the driven post 12; the oblong shape of the second rotating hole 1211 provides movement space for the second rotating shaft 8 when the second rotating rod 132 rotates relative to the driven post 12, and prevents the second rotating rod 132 from getting stuck with the driven post 12 during rotation.

[0080] like Figure 2 As shown, the third rotating hole 1311 is an oblong hole extending along the length of the first rotating rod 131 or the second rotating rod 132, so that the third rotating shaft 9 can move along the extension direction of the third rotating hole 1311 when the first rotating rod 131 and the second rotating rod 132 rotate relative to each other. The third rotating hole 1311 is provided so that the third rotating shaft 9 can move along the third rotating hole 1311 during the relative rotation of the first rotating rod 131 and the second rotating rod 132, preventing the first rotating rod 131 and the second rotating rod 132 from getting stuck during relative rotation.

[0081] As a preferred embodiment of this example, Figure 1 As shown, the lifting mechanism 1 also includes a first guide sleeve 100 disposed on the support frame 120. The first guide sleeve 100 has a first guide cavity inside which guides the movement of the active column 11, and the active column 11 passes through the first guide cavity. By providing the first guide sleeve 100, the up-and-down movement of the active column 11 during the contact action of the contact column can be guided, so that the active column 11 moves along the extension direction of the first guide sleeve 100, avoiding movement deviation of the active column 11 during movement, which helps to improve the support stability of the support tray 2 for the battery pack.

[0082] Furthermore, such as Figure 1 As shown, the lifting mechanism 1 also includes a second guide sleeve 110 disposed on the support frame 120. The second guide sleeve 110 has a second guide cavity inside to guide the movement of the driven column 12, and the driven column 12 passes through the second guide cavity. By providing the second guide sleeve 110, the up-and-down movement of the driven column 12 under the action of the linkage 13 can be guided, so that the driven column 12 moves along the extension direction of the second guide sleeve 110, avoiding movement deviation of the driven column 12 during movement, and helping to improve the support stability of the support tray 2 for the battery pack.

[0083] As a preferred embodiment of this example, Figure 1 , Figure 5As shown, there are multiple driven columns 12, which are distributed at intervals along the circumference of the support tray. Setting the number of driven columns 12 to multiple can improve the uniformity of the support force applied by the driven columns 12 to the support tray 2, and further reduce the probability of the support tray 2 deflecting and overturning due to force offset.

[0084] Furthermore, such as Figure 5 As shown, the tray 2 is square, with four driven columns 12 distributed at its inner corners. The driving column 11 is located on the line connecting the two driven columns 12 on the front side of the tray 2. This arrangement further enhances the support stability of the tray 2 provided by the driven columns 12. Regardless of where the battery pack is located on the tray 2, or when the tray 2 tends to deflect in any direction, the driven columns 12 can always apply a stable supporting force to prevent the tray 2 from tipping over. Furthermore, placing the driving column 11 between the line connecting the two driven columns 12 on the front side of the tray 2 ensures that the abutment column is simultaneously located on the front side of the tray 2, thus easily avoiding the support frame 120 and contributing to the optimization of the structural design of the battery transfer equipment.

[0085] In a preferred embodiment of this invention, two transfer arms 130 are spaced apart on the support frame 120, with the support tray 2 located between the transfer arms 130. Having two transfer arms 130 improves the stability of the transfer arms in supporting the battery pack; and placing the support tray 2 between the two transfer arms 130 allows the battery pack, originally supported by the transfer arms 130, to cover the length of the support tray 2 when supported by it, thus simultaneously improving the stability of the support tray 2 in supporting the battery pack.

[0086] This embodiment also provides a battery swapping station, including a charging rack and the battery transfer equipment described above. The battery swapping station of this application has good adaptability to battery packs of different sizes and with different transfer mileage requirements, and can better meet the battery swapping needs of battery swapping vehicles.

[0087] Example 2:

[0088] This embodiment is largely the same in structure and principle as Embodiment 1, with the only difference being:

[0089] The battery transfer device in this embodiment does not have a lifting mechanism. The bottom of the battery transfer device is provided with an abutment column, which is staggered with the support frame 120. The support frame 120 drives the tray to move down and makes the tray contact the abutment column, thereby causing the tray to move up under the action of the abutment column, so that the tray supports the battery pack and separates it from the transfer arm 130.

[0090] Preferably, the bottom of the supporting tray is provided with the active column described in Embodiment One, which is in alignment with the abutting column. When the supporting tray is driven downward by the supporting frame 120, the active column abuts against the abutting column to lift the supporting tray upward relative to the supporting frame 120.

[0091] Further, the number of active columns is multiple, which are respectively in alignment with the multiple abutting columns. When the supporting tray is driven downward by the supporting frame 120, the multiple active columns respectively abut against the multiple abutting columns to lift the supporting tray upward relative to the supporting frame 120, which improves the stability and carrying capacity of the supporting tray. At the same time, since the multiple active columns work independently, there is no need to set the driven column and the complex connecting structure, which makes the structure of the battery transfer device simpler, easy to assemble and maintain, and improves the stability and durability of the battery transfer device.
