Description

Technical Field

[0001] The utility model relates to the field of battery replacement, and in particular to an emergency transport bracket and battery replacement equipment for transporting battery packs. Background Art

[0002] Battery swap stations used for electric vehicle battery swapping include charging bays that store and charge battery packs. If a battery pack in the bay experiences abnormalities such as overheating, to ensure the safety of the station, the abnormal battery pack must be promptly removed from the bay and transported to the station's battery swap channel by battery swap equipment. A forklift then manually retrieves the abnormal battery pack and disposes of it accordingly, preventing further damage to the station and the battery pack.

[0003] In existing technology, before a forklift can manually pick up an abnormal battery pack, it is necessary to manually attach a sling to the pack, then hang the sling on the forklift, which then lifts the abnormal pack away from the battery swap station. This process requires the operator to directly contact the battery pack, posing a significant safety hazard. Utility Model Content

[0004] The technical problem to be solved by the present invention is to overcome the defect in the prior art that the abnormal battery pack needs to be manually bound with a strap before being transferred by a forklift, which leads to a greater safety hazard, and to provide an emergency transfer bracket and battery replacement equipment for transferring battery packs.

[0005] The utility model solves the above technical problems through the following technical solutions:

[0006] An emergency transfer bracket for transferring a battery pack, the emergency transfer bracket being used to be mounted on a battery swapping platform of a battery swapping device, the emergency transfer bracket comprising:

[0007] The bracket body is used to carry the battery pack;

[0008] The transfer part is connected to the bracket body, and the transfer part is used to be connected to the transfer equipment.

[0009] In this solution, the transfer equipment connects to the transfer portion of the emergency transfer bracket to transfer the battery packs placed on the emergency transfer bracket. Compared to the traditional method of manually tying a rope around the battery pack to connect it to the transfer equipment, this solution uses mechanized operations throughout the entire process, resulting in higher efficiency in battery pack transfers. Furthermore, workers do not need to come into direct contact with the battery packs, improving safety during the transfer process.

[0010] Preferably, a relief area is provided in the middle of the bracket body, and both ends of the relief area are connected in the vertical direction.

[0011] In this solution, since the emergency transfer bracket needs to be installed on the battery exchange equipment during use, setting an avoidance area on the bracket body can reduce the possibility of interference between the bracket body and other components on the battery exchange equipment, so that the height dimension of the emergency transfer bracket can be designed to a smaller value, making the overall structure more compact, improving the stability of the transfer, and reducing the production cost of the emergency transfer bracket.

[0012] Preferably, the emergency transfer bracket further comprises a support member, wherein the support member is connected to the bracket body and extends downward in a vertical direction beyond the lower end surface of the bracket body.

[0013] In this solution, the support member is used to elevate the bracket body, further reducing the possibility of interference between the bracket body and other components on the battery exchange device.

[0014] Preferably, the support member has a first positioning portion, which is located at one end of the support member away from the bracket body in the vertical direction, and the first positioning portion is used to cooperate with the first matching portion of the battery exchange platform.

[0015] In this solution, the first positioning part is used to realize the rapid positioning and installation of the emergency transfer bracket on the battery exchange equipment, further improving the transfer efficiency and reducing the possibility of interference between the emergency transfer equipment and other components on the battery exchange equipment.

[0016] Preferably, the support member is an L-shaped plate, the L-shaped plate forms the first positioning portion, and two side walls of the L-shaped plate are used to abut against the first matching portion.

[0017] In this solution, the first positioning portion is formed using the shape of the support member itself. This saves processing time compared to directly forming the first positioning portion on the support member. Compared to installing another component on the support member as the first positioning portion, this saves assembly time for both, reduces production costs, and reduces the overall weight of the emergency transfer bracket. Furthermore, the emergency transfer bracket is positioned on the battery swap platform by abutting the two side walls of the L-shaped plate with the first mating portion. This requires low positioning accuracy, reduces the difficulty of positioning, and improves the installation efficiency of the emergency transfer bracket on the battery swap platform.

[0018] Preferably, the emergency transfer bracket meets one or more of the following conditions:

[0019] a1. There are four L-shaped plates, which are respectively arranged at the four corners of the bracket body;

[0020] b1. The L-shaped plate is folded toward the outside of the bracket body.

[0021] In this solution, supports are installed at all four corners of the bracket body. This not only improves the stability of the bracket body, allowing the emergency transfer bracket to more stably carry the battery pack, but also enables multi-point positioning of the emergency transfer bracket and the battery swap platform, improving the positioning accuracy of both. The L-shaped plate is folded outward from the bracket body to reduce the horizontal size of the emergency transfer bracket, facilitate its installation, and reduce its production cost.

[0022] Preferably, the bracket body has a second positioning portion, and the second positioning portion is used to cooperate with the second matching portion of the battery tray.

[0023] In this solution, the battery pack remains fixed to the battery tray during transport, and the two are transported together. The second positioning portion is used to quickly position and install the battery tray on the emergency transport bracket, further improving transport efficiency and reducing the possibility of interference between the battery pack, battery tray, and emergency transport equipment.

[0024] Preferably, the second positioning portion is a positioning hole provided on the bracket body, the positioning hole is passed through at both ends in the vertical direction, and the position of the positioning hole corresponds to the position of the first positioning portion.

[0025] In this solution, in the prior art, the lower end of the battery tray is provided at a second mating portion that cooperates with the battery exchange platform. On the one hand, the positioning hole can allow the second mating portion to pass through, thereby realizing rapid positioning and installation of the battery tray and the emergency transfer bracket, and avoiding interference between the battery tray and the emergency transfer bracket; on the other hand, the inner wall of the positioning hole can limit the horizontal movement of the second mating portion and thus limit the horizontal movement of the battery tray, thereby limiting the horizontal movement of the battery pack during transportation and improving the reliability of transportation.

[0026] Preferably, the emergency transfer bracket meets one or more of the following conditions:

[0027] a2. The emergency transfer bracket is provided with weight-reducing holes and / or avoidance holes;

[0028] b2. The emergency transfer bracket further includes an identification portion, which is used to identify the installation direction of the emergency transfer bracket;

[0029] c2. The emergency transfer bracket further includes a limiting member, which is connected to the bracket body and extends upward in a vertical direction beyond the upper end surface of the bracket body;

[0030] d3. The emergency transfer bracket also includes a reinforcing beam, which is connected to the bracket body and is located at the lower end of the bracket body.

[0031] In this solution, the weight-reducing holes can reduce the overall weight of the emergency transfer bracket, facilitating the movement of the battery swapping equipment. The avoidance holes can prevent the emergency transfer bracket from interfering with other components in the battery swapping equipment, thereby improving the feasibility of transporting the battery pack via the emergency transfer bracket. The identification portion is used to indicate the installation direction of the emergency transfer bracket, thereby improving the installation efficiency of the emergency shipping bracket on the battery swapping platform, and thereby improving the efficiency of the transfer. The limiter can limit the excessive movement of the battery pack and the battery bracket in the horizontal direction, reducing the possibility of the battery pack and the battery bracket falling from the emergency transfer bracket. The reinforcing beam can enhance the strength of the emergency transfer bracket, so that the emergency transfer bracket can carry the battery pack more stably.

[0032] Preferably, the bracket body is a frame structure, and the bracket body includes a plurality of beams extending in a horizontal direction, and the plurality of beams are connected to form the bracket body.

[0035] The upper end surface of the first crossbeam forms a carrying portion for carrying the battery pack, and the transfer portions are located at two ends of the carrying portion in the first direction.

[0036] In this solution, the above arrangement reduces the possibility of interference between the transfer equipment and the battery pack and battery tray during the process of removing the battery pack from the emergency transfer bracket, thereby improving the reliability of the transfer.

[0037] Preferably, the two ends of the first beam in the first direction form the transfer portion;

[0038] Alternatively, the emergency transfer bracket further includes a lifting lug, which is fixed on the first crossbeam or the second crossbeam, and the lifting lug extends along a first direction toward the outside of the bracket body, and the lifting lug forms the transfer portion.

[0039] In this solution, the first crossbeam directly serves as the transfer portion of the emergency transfer bracket, simplifying its structure and reducing production costs. Providing additional lugs on the bracket body as the transfer portion reduces the horizontal dimensions of the bracket body, lowering the possibility of interference between the bracket body and other components of the battery swapping equipment, and thus lowering production costs.

[0040] Preferably, the emergency transfer bracket meets one or more of the following conditions:

[0041] a3. When the lifting lugs form the transfer portion, a plurality of the lifting lugs are provided on either side of the bearing portion in the first direction, and the plurality of lifting lugs are spaced apart along the second direction;

[0042] b3. When the lifting ear forms the transfer portion, the lifting ear is fixed to an end of the limiting member of the emergency transfer bracket away from the bracket body in the vertical direction.

[0043] In this solution, multiple lifting lugs are provided on the same side of the load-bearing portion, which increases the contact area between the transfer equipment and the emergency transfer bracket, improving the stability of the transfer equipment when transferring battery packs. Placing the lifting lugs at the upper end of the limiter reduces the possibility of interference between the transfer equipment and other components of the battery swapping equipment, improving the reliability of transfer.

[0044] A battery exchange device comprises a battery tray, a battery exchange platform and an emergency transfer bracket for transferring battery packs as described above, wherein the emergency transfer bracket is placed on the battery exchange platform and the battery tray is placed on the emergency transfer bracket.

[0045] In this solution, the battery pallet is used to carry the battery pack. During the transfer process, the battery pack is placed on the battery pallet, and the battery pallet is placed on the emergency transfer bracket. The transfer equipment can be connected to the transfer part of the emergency transfer bracket to achieve the simultaneous transfer of the battery pack, battery pallet, and emergency transfer bracket. The entire transfer process relies entirely on mechanized operation, which has higher transfer efficiency and the staff does not need to have direct contact with the battery pack, thereby improving the safety of the battery pack during transfer.

[0046] Preferably, the battery swapping device meets one or more of the following conditions:

[0047] a4. The first mating portion of the battery swap platform is a buffer spring, and both side walls of the L-shaped plate of the emergency transfer bracket abut against the buffer spring;

[0048] b4. The second matching portion of the battery tray is a positioning pin, and the positioning pin is inserted into the positioning hole of the emergency transfer bracket.

[0049] In this solution, the buffer spring and positioning pin are both original structures of the battery swapping equipment. Using the existing structures of the battery swapping platform and battery tray as the first mating part and the second mating part can reduce costs.

This utility model can use mechanized operation throughout the process, which has higher efficiency in battery pack transfer and does not require direct contact between workers and battery packs, thereby improving the safety of battery pack transfer.

[0090] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0091] Example 1

[0092] like Figure 1 and Figure 2 As shown, this embodiment discloses a battery swapping device 2 for transferring a battery pack 1 between a charging compartment of a battery swapping station and an electric vehicle to achieve replacement of the battery pack 1 of the electric vehicle.

[0093] like Figure 2-Figure 5 As shown, the battery swap device 2 includes a battery tray 21 and a battery swap platform 22. The battery tray 21 is placed on the battery swap platform 22, and the battery pack 1 is placed on the battery tray 21. During the battery swap process, the battery tray 21 will be transported between the charging compartment and the electric vehicle along with the battery pack 1. The battery tray 21 and the battery pack 1 can be placed together on the battery rack in the charging compartment. Among them, the specific battery swap operation process of the battery swap device 2 belongs to the existing technology and will not be repeated here.

[0094] Further, if Figure 3 and Figure 5 As shown, in order to facilitate the positioning between the battery tray 21 and the battery swap platform 22, a first matching portion 221 is provided on the battery swap platform 22, and a second matching portion 211 is provided on the battery tray 21, and the first matching portion 221 and the second matching portion 211 cooperate with each other. Specifically, the first matching portion 221 of the battery swap platform 22 is a buffer spring, and the second matching portion 211 of the battery tray 21 is a positioning pin, and the buffer spring and the positioning pin are arranged relative to each other. During the battery swap process, when the battery tray 21 is placed on the battery swap platform 22, the positioning pin of the battery tray 21 is inserted into the buffer spring of the battery swap platform 22 to achieve rapid positioning between the battery tray 21 and the battery swap platform 22. The buffer spring is sleeved on the outer periphery of the positioning pin, and can also limit the movement of the positioning pin in the horizontal direction, thereby limiting the movement of the battery tray 21 in the horizontal direction relative to the battery swap platform 22.

[0095] Further, if Figure 3 and Figure 5 As shown, the number of buffer springs and positioning pins in this embodiment is the same and there are four of them. The four buffer springs are arranged at the four corners of the battery exchange platform 22, and the positioning pins are arranged at the four corners of the battery tray 21. The four buffer springs and the four positioning pins are arranged in a one-to-one correspondence, and the positioning pins are inserted into their corresponding buffer springs.

[0096] In other alternative embodiments, the number of buffer springs and positioning pins can also be designed to other values ​​according to actual needs, preferably one buffer spring corresponds to one positioning pin.

[0097] In addition, during the battery replacement process, when the battery tray 21 is placed on the battery replacement platform 22, the upper end of the buffer spring of the battery replacement platform 22 abuts against the lower end surface of the main body of the battery tray 21, thereby buffering the gravity of the battery pack 1 exerted on the battery replacement platform 22 and avoiding direct collision between the two.

[0098] Example 2

[0099] like Figure 6-Figure 9 As shown, based on Example 1, this embodiment further discloses that the battery exchange device 2 also includes an emergency transfer bracket 3 for transferring the battery pack 1. The emergency transfer bracket 3 will not be assembled into the battery exchange device 2 when the battery pack 1 is in normal condition. The emergency transfer bracket 3 will only be assembled into the battery exchange device 2 when an abnormal battery pack 1 appears in the charging compartment.

[0100] like Figure 6-Figure 9 As shown, the emergency transfer bracket 3 is placed on the battery swap platform 22, and the battery tray 21 is placed on the emergency transfer bracket 3. The emergency transfer bracket 3 is used to cooperate with the transfer equipment. The transfer equipment controls the movement of the emergency transfer bracket 3, thereby driving the movement of the battery tray 21 and the battery pack 1 placed on the emergency transfer bracket 3, thereby realizing the transfer of abnormal battery packs 1 and ensuring the safety of the battery swap station.

[0101] like Figure 10-12 As shown, the emergency transfer bracket 3 includes a bracket body 31 and a transfer portion 32 that are connected to each other. The bracket body 31 is used to carry the battery pack 1, and the transfer portion 32 is used to connect to the transfer equipment.

[0102] like Figure 10-12 As shown, the bracket body 31 is used to carry the battery tray 21. Since the battery pack 1 is placed on the battery tray 21, the bracket body 31 can indirectly carry the battery pack 1 placed on the battery tray 21 by carrying the battery tray 21. Specifically, the bracket body 31 in this embodiment is a frame structure. The bracket body 31 includes a plurality of horizontal beams extending in the horizontal direction. The plurality of beams are connected and surround the bracket body 31. Among them, the plurality of beams include two horizontal beams extending in the first direction ( Figure 10 The first crossbeam 311 extending in the X direction of the first crossbeam 311 and the two crossbeams extending in the second direction ( Figure 10The first and second directions in this embodiment are two mutually perpendicular directions on a horizontal plane. The two first beams 311 are connected at both ends of the first direction to the two second beams 312 on either side to form the bracket body 31. The upper end surfaces of the first beams 311 form a supporting portion 313 for supporting the battery pack 1, and the battery tray 21 is placed on the supporting portion 313. The frame structure of the bracket body 31 is conducive to industrial production, is easy to produce and process, and has low production costs.

[0103] Further, if Figure 10 As shown, since the bracket body 31 is formed by connecting crossbeams, an avoidance area is formed in the middle of the bracket body 31, and the avoidance area is connected at both ends in the vertical direction. Since the emergency transfer bracket 3 needs to be installed on the battery exchange device 2 during use, the provision of an avoidance area on the bracket body 31 can reduce the possibility of interference between the bracket body 31 and other components on the battery exchange device 2, so that the height dimension of the emergency transfer bracket 3 can be designed to a smaller value, making the overall structure more compact, improving the stability of the transfer, and reducing the production cost of the emergency transfer bracket 3.

[0104] In other alternative embodiments, the number of beams included in the bracket body 31 may also be other, that is, the number of the first beam 311 and the second beam 312 may be more, and the number of the first beam 311 and the second beam 312 may be the same or different, and the specific design can be based on actual needs.

[0105] In other alternative embodiments, the first beam 311 and the second beam 312 are not limited to being perpendicular to each other in the horizontal plane. The angle between the first beam 311 and the second beam 312 in the horizontal plane can be other angles as long as the first beam 311 and the second beam 312 intersect.

[0106] In other alternative embodiments, the bracket body 31 may also be directly formed on a steel plate. In this state, the steel plate may be cut to form the avoidance area mentioned above.

[0107] like Figure 10-12 As shown, the transfer parts 32 are located at both ends of the load-bearing portion 313 in the first direction. The transfer parts 32 are connected to the bracket body 31, so that the transfer equipment can drive the movement of the emergency transfer bracket 3 as a whole by controlling the movement of the transfer parts 32. Since the battery pack 1 is placed on the load-bearing portion 313, the transfer parts 32 connected to the transfer equipment are arranged at both ends of the load-bearing portion 313 in the first direction. This can reduce the possibility of interference between the transfer equipment and the battery pack 1 and battery tray 21 during the process of removing the battery pack 1 from the emergency transfer bracket 3, thereby improving the reliability of the transfer.

[0108] Specifically, if Figure 10 As shown, the emergency transfer bracket 3 further includes a lifting lug 321 secured to the second crossbeam 312. The lifting lug 321 extends in a first direction toward the exterior of the bracket body 31 and extends beyond the bracket body 31. In this embodiment, the lifting lug 321 forms the transfer portion 32, and the transfer equipment can be a forklift or other device. During transfer, the forklift's fork moves below the lifting lug 321 and abuts against the lower end surface of the lifting lug 321, thereby lifting and moving the emergency transfer bracket 3.

[0109] In this embodiment, a lifting ear 321 is additionally provided on the bracket body 31 as the transfer part 32, which can reduce the horizontal size of the bracket body 31, reduce the possibility of interference between the bracket body 31 and other components in the battery exchange device 2, and reduce production costs.

[0110] In other alternative embodiments, the lifting lug 321 may also be installed on the first crossbeam 311 .

[0111] Further, if Figure 10 As shown, two lifting ears 321 are provided on both sides of the bearing portion 313 in the first direction, and the two lifting ears 321 are spaced apart along the second direction to increase the contact area between the transfer equipment and the emergency transfer bracket 3 and improve the stability of the transfer equipment when transferring the battery pack 1.

[0112] In other alternative embodiments, the number of ears 321 on either side of the load-bearing portion 313 in the first direction may be one or more, and the number of ears 321 on both sides of the load-bearing portion 313 in the first direction may be the same or different, and the specific design can be based on actual needs.

[0113] Further, if Figure 6 and Figure 10 As shown, the emergency transport bracket 3 further includes a stopper 33 connected to the bracket body 31 and extending vertically upward beyond the upper end surface of the bracket body 31. When the battery pack 1 is placed on the emergency transport bracket 3, the stoppers 33 are located on both sides of the battery pack 1 in the first direction, thereby limiting excessive horizontal movement of the battery pack 1 and the battery bracket, reducing the possibility of the battery pack 1 and the battery bracket falling off the emergency transport bracket 3.

[0114] like Figure 10 As shown, the lifting ear 321 is fixed to the end of the limiting member 33 that is away from the bracket body 31 in the vertical direction (i.e., the upper end of the limiting member 33) to raise the position of the lifting ear 321, reserve operating space for the transfer equipment, reduce the possibility of interference between the transfer equipment and other components in the battery exchange equipment 2, and improve the reliability of transfer.

[0115] In other alternative embodiments, the emergency transfer bracket 3 may not be designed with the limit member 33, and the lug 321 extends from the upper end surface of the first beam 311 and / or the second beam 312 along the first direction toward the outside of the bracket body 31.

[0116] In this embodiment, the transfer equipment connects to the transfer portion 32 of the emergency transfer bracket 3 to transfer the emergency transfer bracket 3, thereby transferring the battery pack 1 placed on the emergency transfer bracket 3 to achieve the transfer of the battery pack 1. Compared to the traditional method that requires manual tying of a sling to the battery pack 1 to connect it to the transfer equipment, this embodiment can use mechanized operation throughout the entire process, which improves the transfer efficiency of the battery pack 1 and eliminates the need for workers to directly contact the battery pack 1, thereby improving the safety of the battery pack 1 during transfer.

[0117] Further, if Figure 9 and Figure 12 As shown, the emergency transfer bracket 3 also includes a support member 34, which is connected to the bracket body 31 and extends downward in the vertical direction beyond the lower end surface of the bracket body 31. The support member 34 is used to elevate the bracket body 31, further reducing the possibility of interference between the bracket body 31 and other components on the battery exchange device 2.

[0118] like Figure 9 and Figure 12 As shown, the support member 34 has a first positioning portion 341, which is located at one end of the support member 34 away from the bracket body 31 in the vertical direction. The first positioning portion 341 is used to cooperate with the first matching portion 221 (buffer spring) of the battery swap platform 22. The first positioning portion 341 is used to achieve rapid positioning and installation of the emergency transfer bracket 3 on the battery swap device 2, further improving the transfer efficiency and reducing the possibility of interference between the emergency transfer device and other components on the battery swap device 2.

[0119] Specifically, if Figure 12 As shown, the support member 34 is an L-shaped plate, and the L-shaped plate forms a first positioning portion 341. The two side walls of the L-shaped plate are used to abut against the first matching portion 221, that is, the two side walls of the L-shaped plate of the emergency transfer bracket 3 are both in abutment with the buffer spring. This embodiment uses the shape of the support member 34 itself to form the first positioning portion 341, which can save processing time compared to directly processing the first positioning portion 341 on the support member 34. Compared with installing another component on the support member 34 as the first positioning portion 341, it can save assembly time for both, reduce production costs, and reduce the overall weight of the emergency transfer bracket 3. Moreover, the positioning of the emergency transfer bracket 3 on the battery exchange platform 22 is achieved by abutting the two side walls of the L-shaped plate with the first matching portion 221. The positioning accuracy requirement is low, which reduces the difficulty of positioning the two and improves the installation efficiency of the emergency transfer bracket 3 on the battery exchange platform 22.

[0120] In addition, the buffer spring is the original structure of the battery exchange device 2. Using the existing structure of the battery exchange platform 22 as the first matching part 221 that cooperates with the first positioning part 341 can reduce costs.

[0121] like Figure 12 As shown, the number of L-shaped plates in this embodiment is the same as the number of buffer springs, namely four. The four L-shaped plates are respectively arranged at the four corners of the bracket body 31 and correspond to the positions of the buffer springs. In this embodiment, support members 34 are provided at the four corners of the bracket body 31. On the one hand, this can improve the stability of the support of the bracket body 31, so that the emergency transfer bracket 3 can more stably carry the battery pack 1; on the other hand, it can achieve multi-point positioning of the emergency transfer bracket 3 and the battery swap platform 22, improving the positioning accuracy of both.

[0122] In other alternative embodiments, the number of L-shaped plates can also be adjusted according to the number of first matching parts 221 of the battery exchange platform 22, and preferably the number of the two is the same.

[0123] Further, if Figure 9 and Figure 12 As shown, the L-shaped plate is folded toward the outside of the bracket body 31 to reduce the horizontal size of the emergency transfer bracket 3, facilitate the installation of the emergency transfer bracket 3, and reduce the production cost of the emergency transfer bracket 3.

[0124] In other alternative embodiments, the L-shaped plate may also be folded toward the inside of the bracket body 31 .

[0125] During the transportation of the battery pack 1, the battery pack 1 is always fixed on the battery tray 21, and the two are transported together. Figure 9 and Figure 10 As shown, the bracket body 31 has a second positioning portion 314, which is used to mate with the second mating portion 211 of the battery tray 21. The second positioning portion 314 is used to quickly position and install the battery tray 21 on the emergency transport bracket 3, further improving transport efficiency and reducing the possibility of interference between the battery pack 1, battery tray 21, and emergency transport equipment.

[0126] Specifically, if Figure 9 and Figure 10As shown, the second positioning portion 314 is a positioning hole provided on the bracket body 31. The positioning hole is vertically continuous at both ends. The position of the positioning hole corresponds to the position of the first positioning portion 341. The positioning pin is passed through the positioning hole of the emergency transfer bracket 3. Since the lower end of the battery tray 21 is provided with a positioning pin that cooperates with the battery exchange platform 22, the positioning hole can, on the one hand, allow the positioning pin to pass through, thereby achieving rapid positioning and installation of the battery tray 21 and the emergency transfer bracket 3, and avoiding interference between the battery tray 21 and the emergency transfer bracket 3; on the other hand, the inner wall of the positioning hole can limit the horizontal movement of the positioning pin and thus limit the horizontal movement of the battery tray 21, thereby limiting the horizontal movement of the battery pack 1 during the transfer process and improving the reliability of the transfer.

[0127] In addition, the positioning pin is the original structure of the battery exchange device 2. Using the existing structure of the battery tray 21 as the second matching part 211 that matches the second positioning part 314 can reduce costs.

[0128] like Figure 10 As shown, the number of positioning holes and the number of positioning pins in this embodiment are the same, both four. The four positioning holes are respectively provided at the four corners of the bracket body 31 and correspond to the positions of the positioning pins. In other alternative embodiments, the number of positioning holes can also be adjusted according to the number of second mating portions 211 of the battery tray 21, and preferably the two are the same.

[0129] Further, if Figure 10 As shown, the emergency transfer bracket 3 is provided with a weight-reducing hole 35. The weight-reducing hole 35 in this embodiment is specifically arranged on the limiting part 33. The weight-reducing hole 35 is through-connected at both ends in the first direction. The weight-reducing hole 35 can reduce the overall weight of the emergency transfer bracket 3 and facilitate the movement of the battery exchange equipment 2.

[0130] Further, if Figure 10 As shown, the emergency transfer bracket 3 is further provided with an avoidance hole 36. In this embodiment, the avoidance hole 36 is specifically arranged on the second crossbeam 312 and the limit member 33. The two ends of the avoidance hole 36 in the vertical direction pass through the overlapping area of ​​the second crossbeam 312 and the support member 34. The avoidance hole 36 can prevent the emergency transfer bracket 3 from interfering with other components in the battery swapping device 2, thereby improving the feasibility of transporting the battery pack 1 through the emergency transfer bracket 3.

[0131] In other alternative embodiments, whether to set the weight-reducing hole 35 and / or the avoidance hole 36 is determined as needed according to the actual situation of the battery exchange device 2. The weight-reducing hole 35 and / or the avoidance hole 36 can also be set at other positions of the emergency transfer bracket 3.

[0132] Example 3

[0133] like Figure 12-16As shown, based on Example 1, this embodiment further discloses that the battery exchange device 2 also includes an emergency transfer bracket 3 for transferring the battery pack 1. The emergency transfer bracket 3 will not be assembled into the battery exchange device 2 when the battery pack 1 is in normal condition. The emergency transfer bracket 3 will only be assembled into the battery exchange device 2 when an abnormal battery pack 1 appears in the charging compartment.

[0134] like Figure 12-16 As shown, the emergency transfer bracket 3 is placed on the battery swap platform 22, and the battery tray 21 is placed on the emergency transfer bracket 3. The emergency transfer bracket 3 is used to cooperate with the transfer equipment. The transfer equipment controls the movement of the emergency transfer bracket 3, thereby driving the movement of the battery tray 21 and the battery pack 1 placed on the emergency transfer bracket 3, thereby realizing the transfer of abnormal battery packs 1 and ensuring the safety of the battery swap station.

[0135] Among them, this embodiment Figure 12-16 The specific structure of the battery replacement device 2 shown is the same as that in Example 1. Figure 1-Figure 5 The specific structure of the battery replacement device 2 shown is not exactly the same. Figure 12-16 It is only to illustrate the installation position of the emergency transfer equipment in the battery exchange equipment 2.

[0136] like Figure 17 As shown, the emergency transfer bracket 3 includes a bracket body 31 and a transfer portion 32 that are connected to each other. The bracket body 31 is used to carry the battery pack 1, and the transfer portion 32 is used to connect to the transfer equipment.

[0137] like Figure 17 As shown, the bracket body 31 is used to carry the battery tray 21. Since the battery pack 1 is placed on the battery tray 21, the bracket body 31 can indirectly carry the battery pack 1 placed on the battery tray 21 by carrying the battery tray 21. Specifically, the bracket body 31 in this embodiment is a frame structure. The bracket body 31 includes a plurality of horizontal beams extending in the horizontal direction. The plurality of beams are connected and surround the bracket body 31. Among them, the plurality of beams include two horizontal beams extending in the first direction ( Figure 17 The first crossbeam 311 extending in the X direction of the first crossbeam 311 and the two crossbeams extending in the second direction ( Figure 17 The first and second directions in this embodiment are two mutually perpendicular directions on a horizontal plane. The two first beams 311 are connected at both ends of the first direction to the two second beams 312 on either side to form the bracket body 31. The upper end surface of the first beam 311 forms a supporting portion 313 for supporting the battery pack 1, and the battery tray 21 is placed on the supporting portion 313. The frame structure of the bracket body 31 is conducive to industrial production, is easy to produce and process, and has low production costs.

[0138] Further, if Figure 17As shown, since the bracket body 31 is formed by connecting crossbeams, an avoidance area is formed in the middle of the bracket body 31, and the avoidance area is connected at both ends in the vertical direction. Since the emergency transfer bracket 3 needs to be installed on the battery exchange device 2 during use, the provision of an avoidance area on the bracket body 31 can reduce the possibility of interference between the bracket body 31 and other components on the battery exchange device 2, so that the height dimension of the emergency transfer bracket 3 can be designed to a smaller value, making the overall structure more compact, improving the stability of the transfer, and reducing the production cost of the emergency transfer bracket 3.

[0139] In other alternative embodiments, the number of beams included in the bracket body 31 may also be other, that is, the number of the first beam 311 and the second beam 312 may be more, and the number of the first beam 311 and the second beam 312 may be the same or different, and the specific design can be based on actual needs.

[0140] In other alternative embodiments, the first beam 311 and the second beam 312 are not limited to being perpendicular to each other in the horizontal plane. The angle between the first beam 311 and the second beam 312 in the horizontal plane can be other angles as long as the first beam 311 and the second beam 312 intersect.

[0141] In other alternative embodiments, the bracket body 31 may also be directly formed on a steel plate. In this state, the steel plate may be cut to form the avoidance area mentioned above.

[0142] like Figure 17 As shown, the transfer parts 32 are located at both ends of the load-bearing portion 313 in the first direction. The transfer parts 32 are connected to the bracket body 31, so that the transfer equipment can drive the movement of the emergency transfer bracket 3 as a whole by controlling the movement of the transfer parts 32. Since the battery pack 1 is placed on the load-bearing portion 313, the transfer parts 32 connected to the transfer equipment are arranged at both ends of the load-bearing portion 313 in the first direction. This can reduce the possibility of interference between the transfer equipment and the battery pack 1 and battery tray 21 during the process of removing the battery pack 1 from the emergency transfer bracket 3, thereby improving the reliability of the transfer.

[0143] Specifically, if Figure 17 As shown, the first crossbeam 311 forms transfer sections 32 at both ends in the first direction, and a load-bearing section 313 in the middle section of the first crossbeam 311 in the first direction. The battery pack 1 is placed on the upper end of the middle section of the first crossbeam 311, while the lower ends of the first crossbeam 311 in the first direction abut against the forks of a forklift. The first crossbeam 311 directly serves as the transfer section 32 of the emergency transfer bracket 3, simplifying its structure and reducing production costs.

[0144] In this embodiment, the transfer equipment connects to the transfer portion 32 of the emergency transfer bracket 3 to transfer the emergency transfer bracket 3, thereby transferring the battery pack 1 placed on the emergency transfer bracket 3 to achieve the transfer of the battery pack 1. Compared to the traditional method that requires manual tying of a sling to the battery pack 1 to connect it to the transfer equipment, this embodiment can use mechanized operation throughout the entire process, which improves the transfer efficiency of the battery pack 1 and eliminates the need for workers to directly contact the battery pack 1, thereby improving the safety of the battery pack 1 during transfer.

[0145] Further, if Figure 16 and Figure 17 As shown, the emergency transfer bracket 3 also includes a support member 34, which is connected to the bracket body 31 and extends downward in the vertical direction beyond the lower end surface of the bracket body 31. The support member 34 is used to elevate the bracket body 31, further reducing the possibility of interference between the bracket body 31 and other components on the battery exchange device 2.

[0146] like Figure 16 and Figure 17 As shown, the support member 34 has a first positioning portion 341, which is located at one end of the support member 34 away from the bracket body 31 in the vertical direction. The first positioning portion 341 is used to cooperate with the first matching portion 221 (buffer spring) of the battery swap platform 22. The first positioning portion 341 is used to achieve rapid positioning and installation of the emergency transfer bracket 3 on the battery swap device 2, further improving the transfer efficiency and reducing the possibility of interference between the emergency transfer device and other components on the battery swap device 2.

[0147] Specifically, if Figure 17 As shown, the support member 34 is an L-shaped plate, and the L-shaped plate forms a first positioning portion 341. The two side walls of the L-shaped plate are used to abut against the first matching portion 221, that is, the two side walls of the L-shaped plate of the emergency transfer bracket 3 are both in abutment with the buffer spring. This embodiment uses the shape of the support member 34 itself to form the first positioning portion 341, which can save processing time compared to directly processing the first positioning portion 341 on the support member 34. Compared with installing another component on the support member 34 as the first positioning portion 341, it can save assembly time for both, reduce production costs, and reduce the overall weight of the emergency transfer bracket 3. Moreover, the positioning of the emergency transfer bracket 3 on the battery exchange platform 22 is achieved by abutting the two side walls of the L-shaped plate with the first matching portion 221. The positioning accuracy requirement is low, which reduces the difficulty of positioning the two and improves the installation efficiency of the emergency transfer bracket 3 on the battery exchange platform 22.

[0148] In addition, the buffer spring is the original structure of the battery exchange device 2. Using the existing structure of the battery exchange platform 22 as the first matching part 221 that cooperates with the first positioning part 341 can reduce costs.

[0149] like Figure 12 As shown, the number of L-shaped plates in this embodiment is the same as the number of buffer springs, namely four. The four L-shaped plates are respectively arranged at the four corners of the bracket body 31 and correspond to the positions of the buffer springs. In this embodiment, support members 34 are provided at the four corners of the bracket body 31. On the one hand, this can improve the stability of the support of the bracket body 31, so that the emergency transfer bracket 3 can more stably carry the battery pack 1; on the other hand, it can achieve multi-point positioning of the emergency transfer bracket 3 and the battery swap platform 22, improving the positioning accuracy of both.

[0150] In other alternative embodiments, the number of L-shaped plates can also be adjusted according to the number of first matching parts 221 of the battery exchange platform 22, and preferably the number of the two is the same.

[0151] Further, if Figure 9 and Figure 12 As shown, the L-shaped plate is folded toward the outside of the bracket body 31 to reduce the horizontal size of the emergency transfer bracket 3, facilitate the installation of the emergency transfer bracket 3, and reduce the production cost of the emergency transfer bracket 3.

[0152] In other alternative embodiments, the L-shaped plate may also be folded toward the inside of the bracket body 31 .

[0153] Furthermore, as shown in Figure 17 , the emergency transport bracket 3 also includes a stopper 33, which is connected to the bracket body 31 and extends vertically upward beyond the upper end surface of the bracket body 31. When the battery pack 1 is placed on the emergency transport bracket 3, the stoppers 33 are located on both sides of the battery pack 1 in the first direction, thereby limiting excessive horizontal movement of the battery pack 1 and the battery bracket, and reducing the possibility of the battery pack 1 and the battery bracket falling off the emergency transport bracket 3.

[0154] Among them, Figure 17 As shown, the support member 34 and the limiting member 33 in this embodiment are the same vertical beam structure, and the first cross beam 311 and the second cross beam 312 are connected to each other through the vertical beam.

[0155] Further, if Figure 17 As shown, the emergency transfer bracket 3 also includes an identification portion 37, which is used to identify the installation direction of the emergency transfer bracket 3, thereby improving the installation efficiency of the emergency shipping bracket on the battery swap platform 22 and thus improving the efficiency of transfer. In this embodiment, the identification portion 37 is an upward-pointing arrow to facilitate staff to distinguish which end of the emergency transfer bracket 3 is facing upward, facilitating the rapid installation of the emergency transfer bracket 3 on the battery swap platform 22.

[0156] In other alternative embodiments, the identification portion 37 may also include guidance for other installation directions, such as which side of the battery swap platform 22 the first crossbeam 311 and the second crossbeam 312 are placed on. Alternatively, if the structure of the emergency transfer bracket 3 is easy to distinguish, the identification portion 37 may not be provided separately.

[0157] Further, if Figure 17 As shown, the emergency transfer bracket 3 further includes a reinforcing beam 38, which is connected to the bracket body 31 and is located at the lower end of the bracket body 31. In this embodiment, the reinforcing beam 38 extends along the first direction and is installed below the first crossbeam 311. The reinforcing beam 38 can enhance the strength of the emergency transfer bracket 3, allowing the emergency transfer bracket 3 to more stably carry the battery pack 1.

[0158] In other alternative embodiments, the reinforcement beam 38 may also be designed to extend along the second direction and be disposed below the second cross beam 312. Alternatively, if the emergency transfer bracket 3 is strong enough, the reinforcement beam 38 may not be separately provided.
