[0002] There are currently many challenges in the maintenance of battery packs for D-type vehicles in urban areas. After the battery packs are removed from the vehicle, they can only be transported between the work site and the battery repair room using a pallet. The support provided by the pallet is limited, and the surface of the battery is easily damaged during transport. In some cases, internal damage may even occur, affecting the performance and lifespan of the battery. Utility Model Content
[0003] The purpose of this utility model is to overcome the shortcomings of the prior art. This utility model provides a battery transfer fixture. By setting EPDM rubber on the support seat, the EPDM rubber absorbs the impact force when the battery is placed on the support seat, avoiding collision between the battery and the support seat when the battery is placed on the battery transfer fixture, and reducing damage to the battery surface.
[0004] Accordingly, this utility model proposes a battery transfer fixture, which includes: a support base and at least one placement rack; The placement rack is mounted on the support base. Each placement rack includes a placement frame, a fixed side bracket, and a connecting pipe. The placement frame forms a placement area for placing the battery on the support base. The connecting pipe is mounted on the support base and coincides with the central axis of the corresponding placement area. The surfaces of both the connecting pipe and the bearing seat are covered with EPDM rubber. The fixed side bracket is located at the edge of the corresponding placement area. The fixed side bracket includes a first side bracket and a second side bracket. The second side bracket is located on top of the first side bracket and is hinged to the first side bracket.
[0005] Preferably, the bearing seat includes multiple parallel first bearing tubes and two parallel second bearing tubes; Both ends of any one of the first bearing tubes are fixedly connected to the two second bearing tubes respectively.
[0006] Preferably, both the first carrier tube and the second carrier tube are hollow carrier tubes.
[0007] Preferably, the cross-sections of the first and second bearing tubes are rectangular.
[0008] Preferably, the distance between any two adjacent first bearing pipes is equal.
[0009] Preferably, the cross-section of the connecting pipe is rectangular, and the cross-sectional area of the first bearing pipe and the second bearing pipe is S1, and the cross-sectional area of the connecting pipe is S2; The constraint relationship between S1 and S2 is S2 > S1.
[0010] Preferably, the fixed side bracket is provided with a plurality of movable hinges, and the first side bracket is hinged to the second side bracket based on the plurality of movable hinges.

Detailed Implementation
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0019] Figure 1 This shows a schematic diagram of the first structure of the battery transfer fixture in this utility model. Figure 2 This shows a front view of the battery transfer fixture of this invention. Figure 3A side view of the battery transfer fixture of this utility model is shown. The battery transfer fixture includes: a support base 1 and at least one placement rack 2. The placement rack 2 is mounted on the support base 1. Each placement rack 2 includes: a placement frame 21, a fixed side bracket 22, and a connecting pipe 23. The placement frame 21 forms a placement area 20 for placing batteries on the support base. The connecting pipe 23 is mounted on the support base and coincides with the central axis of the corresponding placement area 200. The surfaces of the connecting pipe 23 and the support base 1 are both provided with EPDM rubber 4. The fixed side bracket 22 is located at the edge of the corresponding placement area 20. The fixed side bracket 22 includes a first side bracket 221 and a second side bracket 222. The second side bracket 222 is located on top of the first side bracket 221 and is hinged to the first side bracket 221. In this embodiment, the battery transfer fixture includes a support base 1 and two placement frames 2. The two placement frames respectively enclose two placement areas 20. The number of placement frames 2 can be adjusted according to actual conditions, that is, the number of placement frames can be one, three, or even more. When the number of placement frames 2 is adjusted, the placement areas 20 formed on the battery transfer fixture are also adjusted simultaneously, which can be regarded as one placement frame enclosing one placement area 20. That is, the battery transfer fixture can carry multiple batteries at the same time, reducing the number of handling operations and improving the efficiency of battery transfer. When the battery transfer fixture is provided with two placement frames 21, a protective gap 200 is left between the two placement areas 20. This protective gap 200 avoids the collision of two adjacent batteries when the batteries are affected by external forces and vibrate during transportation, thus reducing the risk of damage. It keeps the batteries at a certain distance with sufficient space, reducing the risk of collision between two adjacent batteries. The surfaces of the connecting pipe 23 and the support base 1 are coated with EPDM rubber 4. The copolymer structure of EPDM rubber 4 gives it high resilience, effectively absorbing impact energy and quickly recovering its deformation. When a heavy battery is placed on the surface of the support base 1 or comes into contact with the surface of the connecting pipe 23, the EPDM rubber 4 deforms under the weight of the battery, thereby absorbing the impact force of the battery on the support base 1 or the connecting pipe 23. This prevents the battery from colliding with the support base 1 when placed on the battery transport fixture. EPDM rubber 4 effectively absorbs the impact force between the battery and the support base 1, reducing the risk of damage caused by collision. Simultaneously, when EPDM rubber 4 deforms under force, it increases the contact area between the battery and the EPDM rubber 4, thereby increasing the friction between them. This helps reduce the risk of the battery moving independently or swaying laterally during the transport fixture's movement, keeping the battery relatively stable during transport.Furthermore, the EPDM rubber 4 has excellent insulation properties, and its application on the surface of the bearing seat 1 and the connecting pipe 23 prevents electric shock accidents caused by the support, providing strong protection for the personal safety of maintenance personnel. The first side support 221 is hinged to the second side support 222. When the first side support 221 is subjected to force, it rotates 90° around the hinge point of the first side support 221 and the second side support 222, thereby reducing the height of the entire fixed side support 22. Conversely, when the first side support 221 is subjected to force, it rotates 90° around the hinge point of the first side support 221 and the second side support 222, restoring the fixed side support 22 to its original height. Thus, the fixed side support 22 can flexibly adjust the side plate state, allowing it to have two different heights, supporting two sizes of battery packs installed on the train, and improving the versatility of the battery rotation tool. When the second side bracket 222 rotates to a position above the first side bracket 221, the height of the fixed side bracket 22 increases, allowing the taller battery pack to be placed in the placement area. The upper surface of the fixed side bracket 22 is flush with the upper surface of the battery pack, making the entire device more evenly stressed in the horizontal direction and reducing local stress concentration caused by height differences. This improves the stability of the device when placing the battery pack and reduces the risk of damage to the battery pack due to shaking or tilting. When the second side bracket 222 rotates to a position to the side of the first side bracket 221, the height of the fixed side bracket 22 returns to its original height, allowing the shorter battery pack to be placed in the placement area. The upper surface of the fixed side bracket 22 is either flush with or higher than the upper surface of the battery pack, preventing the upper surface of the battery pack from protruding beyond the fixed side bracket 22. This effectively reduces the risk of operators or other objects accidentally colliding with the protruding battery pack during equipment use, thus reducing the probability of safety accidents.
[0020] Furthermore, the support base 1 includes multiple parallel first support tubes 11 and two parallel second support tubes 12; both ends of any one of the first support tubes 11 are fixedly connected to the two second support tubes 12 respectively. In this embodiment, the support base 1 includes five parallel first support tubes 11 and two parallel second support tubes 12. One end of one of the five first support tubes 11 is welded to the side wall of one of the second support tubes 12, and the other end of the first support tube 11 is connected to another second support tube 12, and so on. The two ends of the remaining four first support tubes 11 are welded and fixed to the two second support tubes 12 respectively, thereby forming a support base 1 assembly with a stable structure and strong load-bearing capacity. A certain distance is left between the five first support tubes 11 to increase the contact area between the bottom of the battery and the external environment, accelerate the heat exchange rate between the battery and the external environment, and thus improve the cooling rate of the battery.
[0021] It should be noted that the support base 1 also includes a third support tube 13, which is arranged parallel to the two second support tubes 12 and located between the two second support tubes 12. The third support tube 13 is located at the bottom of the five first support tubes 11 and is connected to the bottom of the five first support tubes 11, thereby reducing the risk of bending of the middle area of the five first support tubes 11 under stress.
[0022] Furthermore, both the first carrier tube 11 and the second carrier tube 12 are hollow carrier tubes. In this embodiment, the hollow carrier tubes reduce the weight of the entire transfer fixture while maintaining the structural strength of the first carrier tube 11 and the second carrier tube 12. The hollow carrier tube has a hollow cavity, allowing airflow to enter and flow along the cavity to carry the heat transferred from the battery to the hollow carrier tube to the external environment. This accelerates the heat dissipation efficiency of the first carrier tube 11 and the second carrier tube 12, promptly reduces their temperature, improves the uniformity of the tube wall temperature, and significantly extends the service life of the first carrier tube 11 and the second carrier tube 12 in high-temperature environments.
[0023] Furthermore, the cross-sections of the first support tube 11 and the second support tube 12 are rectangular. In this embodiment, the cross-sectional area of the first support tube 11 and the second support tube 12 is a square. A square is a closed shape with uniform material distribution, which can effectively resist bending and torsional forces. When the square cross-section is subjected to axial compression, the stress is evenly distributed along the wall thickness, avoiding stress concentration caused by local buckling of the circular cross-section. This helps to reduce the risk of deformation of the first support tube 11 or the second support tube 12 due to stress concentration. The first support tube 11 is a square tube, and five first support tubes 11 arranged in parallel can form a support surface, which is beneficial for stably supporting the battery on the support seat 1.
[0024] Furthermore, the distance between any two adjacent first support tubes 11 is equal. In this embodiment, the distance between two adjacent first support tubes 11 is equal, meaning that each first support tube 11 provides support in the same direction to the bottom of the corresponding battery. The five first support tubes 11 simultaneously provide support to the battery from five directions, ensuring that the battery can be stably fixed on the support base 1. A certain gap is left between two adjacent first support tubes 11. This gap provides space for the user to provide a point of leverage to lift the battery from the support base 1 or provides space for the user to accommodate their hands, reducing the risk of the hand being trapped between the battery and the support base 1. Similarly, this gap provides space for the device to wind up the battery, facilitating the movement of the battery.
[0025] Furthermore, the cross-section of the connecting pipe 23 is rectangular, and the cross-sectional areas of the first bearing pipe 11 and the second bearing pipe 12 are S1 and S2, respectively; the constraint relationship between S1 and S2 is S2 > S1. In this embodiment, the cross-sectional area of the connecting pipe 23 is a square, which is a closed shape, resulting in uniform material distribution and effective resistance to bending and torsional forces. When the square cross-section is subjected to axial compression, the stress is evenly distributed along the wall thickness, avoiding stress concentration caused by local buckling of the circular cross-section, thus reducing the risk of deformation of the connecting pipe 23 due to stress concentration. The connecting pipe 23 is located in the placement area 20. When the transfer fixture places the battery, the connecting pipe 23 and the placement frame 21 can clamp the battery in the placement area 20, reducing the movable space of the battery, reducing the risk of the battery moving independently, and ensuring that the battery is stably fixed in the placement area 20. The cross-sectional area of the connecting pipe 23 is larger than that of the first bearing pipe 11 or the second bearing pipe 12. Since the connecting pipe 23 is connected to five of the first bearing pipes 11 at the same time, part of the stress of the first bearing pipes 11 can be distributed to the connecting pipe 23. When the battery is placed in the placement area 20, the side wall of the battery abuts against the side wall of the connecting pipe 23. At this time, the connecting pipe 23 needs to bear the force of the battery and the stress distributed by the five connecting pipes 23 at the same time. Therefore, the cross-sectional area of the connecting pipe 23 is larger than that of the connecting pipe 23, which is beneficial to increase the bending and torsional stiffness of the connecting pipe 23, thereby strengthening the structural strength of the battery transfer fixture.
[0026] Furthermore, the fixed side bracket 22 is provided with a plurality of movable hinges 223, and the first side bracket 221 is hinged to the second side bracket 222 based on the plurality of movable hinges 223. In this embodiment, the fixed side bracket 22 is provided with three movable hinges 223, that is, the first side bracket 221 is hinged to the second side bracket 222 based on the three movable hinges 223. The three movable hinges 223 are respectively located at both ends and the middle of the first side bracket 221. The three movable hinges 223 hinge the first side bracket 221 and the second side bracket 222 from three positions. The three hinge points transform the connection between the first side bracket 221 and the second side bracket 222 into a statically determinate structure, which can effectively disperse external loads and avoid local stress concentration caused by single-point or double-point connection, which could lead to damage to the fixed side bracket 22, and thus help to strengthen the structural strength of the fixed side bracket 22.
[0027] Furthermore, the placement frame 21 includes a U-shaped frame 211 and multiple support tubes 212, with the multiple support tubes 212 located at the bottom of the U-shaped frame 211; one end of any support tube 212 is fixedly connected to the U-shaped frame 211, and the other end of the support tube 212 is fixedly connected to the support base 1. In this embodiment, the placement frame 21 includes one U-shaped frame 211 and four support tubes 212, with the four support tubes 212 respectively located at the four apex corners of the U-shaped frame 211, raising the U-shaped frame 211 to the same height as the corresponding battery, ensuring that the U-shaped frame 211 surrounds the corresponding battery and abuts against the battery, limiting the battery's range of movement, ensuring that the battery is stably placed on the support base 1 during transportation, avoiding the risk of the battery moving independently and falling off the support base 1, and facilitating the stable fixing of the battery on the support base 1.
[0028] Furthermore, the support base 1 and the placement frame 2 are made of metal. In this embodiment, the support base 1 and the placement frame 2 are made of aluminum alloy. Aluminum alloy has a low density but high hardness, which greatly reduces the weight of the tooling itself while ensuring that the tooling has a certain load-bearing capacity. This makes it easier for operators to handle the batteries and reduces labor intensity. At the same time, aluminum alloy also has good corrosion resistance, which can resist the erosion of corrosive substances such as electrolyte that may leak from the battery to a certain extent, extending the service life of the tooling.
[0029] Furthermore, the bottom of the support base 1 is provided with multiple movable rollers 3, which are correspondingly distributed at the top corners of the support base 1. In this embodiment, the bottom of the support base 1 is provided with four movable rollers 3, which are respectively located at the four top corners of the support base 1, that is, one of the four movable rollers 3 is located at one of the four top corners of the support base 1. The four movable rollers 3 located at the four top corners of the bottom of the support base 1 can form a quadrilateral support mechanism, ensuring that the four movable rollers 3 can raise the support base 1 to a certain height, making it convenient for employees to use a forklift to move the entire battery rotating fixture.
[0030] It should be noted that the movable roller 3 is a universal wheel, which facilitates the movement of the battery transfer fixture in different directions on the plane.
[0031] In summary, this utility model, by incorporating EPDM rubber on the support seat of the battery transfer fixture, absorbs the impact force of the battery being placed on the support seat, preventing the battery from colliding with the support seat when placed on the battery transfer fixture, thus reducing damage to the battery surface. Simultaneously, when the EPDM rubber deforms under stress, it increases the contact area between the battery and the EPDM rubber, thereby increasing the friction between them. This helps reduce the risk of the battery moving independently or swaying left or right during the transfer process, ensuring the battery remains relatively stable during transport.
[0032] Furthermore, the above description provides a detailed introduction to a battery transfer fixture provided by the embodiments of this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
