[0002] With the increasing popularity of new energy electric vehicles, construction machinery has also begun to adopt electric products in recent years. The convenience of after-sales maintenance and repair has become a more pressing issue. As a core component of electric loaders, the battery pack houses high-voltage battery modules that store energy and power the electric loader. For new energy construction vehicles, such as loaders and excavators, the battery packs are typically located behind the cab and on both sides of the vehicle frame. To improve the vehicle's range, a sufficient number of battery packs are required, and multiple battery packs are arranged in an array on the mounting rack.

[0003] During maintenance and repair, the entire battery pack must be removed from the vehicle, making its removal and installation a key design consideration. The battery pack's installation location and surrounding components vary for different vehicle types and models. Some vehicle battery packs have convenient mounting points, while others, due to structural limitations, have mounting points located on the battery floor. This makes assembly and disassembly difficult for battery packs arranged in multiple rows and columns, especially those on the upper level, which lack clearance due to the limitations of the lower level battery packs. Consequently, the entire battery assembly must be disassembled and then removed piecemeal from the bottom up, significantly increasing the workload. Utility Model Content

[0030] It should be noted that the directional terms "up" and "down" in the claims, description and drawings of the present invention are the same as the up and down directions of the vehicle body, and the term "inner side" refers to the side close to the center of the mounting frame, and vice versa.

[0031] Please also refer to Figures 1 to 3 The battery pack mounting assembly and vehicle provided by the present invention are now described. The battery pack mounting assembly includes a mounting frame 1, multiple support plates 2, and multiple mounting plates 3. The mounting frame 1 has multiple mounting cavities sequentially distributed along the vertical direction. Each mounting cavity includes multiple receiving chambers sequentially distributed along a first path, the first path being perpendicular to the vertical direction. The multiple support plates 2 are arranged in a one-to-one correspondence with the receiving chambers. The support plates 2 are disposed within the receiving chambers and connected to the mounting frame 1. The multiple mounting plates 3 are arranged in a one-to-one correspondence with the receiving chambers. The mounting plates 3 include a mounting area 301 and a fixing area 302 disposed outside the mounting area 301. The mounting area 301 corresponds to the battery pack 5 and is used to connect to the battery pack 5. The fixing area 302 is connected to the support plate 2.

[0032] Compared with the prior art, the battery pack installation assembly provided by the present invention is connected to the battery pack 5 through the installation plate 3, and the battery pack 5 is fixed to the installation area 301. Since the fixing area 302 is located on the outside of the installation area 301, after the battery pack 5 is fixed to the installation area 301, the fixing area 302 is still exposed to the outer plate and is not shielded by the battery pack 5. The battery module formed by the battery pack 5 and the installation plate 3 is placed in the accommodation chamber, and the fixing area 302 is connected to the support plate 2. In the present invention, the support plate 2 provides support force for the battery module formed by the installation plate 3 and the battery pack 5, ensuring the connection stability and reliability of the battery pack 5. In addition, since the fixing area 302 of the installation plate 3 is exposed to the battery pack 5, the fixing area 302 can be directly separated from the support plate 2 when disassembling the battery pack 5. Compared with the solution in the prior art in which the bottom of the battery pack 5 is fixed to the support plate 2, there is no need to disassemble the entire battery pack installation assembly from the vehicle body and then disassemble the battery pack 5 one by one from bottom to top, which improves the convenience of disassembly and assembly and work efficiency in the maintenance of the battery pack 5.

[0033] Optionally, the fixing area 302 is arranged around the outer periphery of the installation area 301 .

[0034] Specifically, the fixing area 302 is detachably connected to the support plate 2 , for example, by screwing or clamping.

[0035] Optionally, the fixing area 302 is provided with a clamping piece, the support plate 2 is provided with a clamping hole adapted to the clamping frame, and the clamping piece is inserted into the clamping hole to achieve a clamping fit.

[0036] In some embodiments, see Figure 2 The installation area 301 is distributed with a plurality of installation positions, and the plurality of installation positions are distributed in the installation area 301 at intervals along the first path.

[0037] Multiple mounting locations are connected to the battery pack 5, increasing the number of connection points between the mounting area 301 and the battery pack 5 and improving the stability and firmness of the connection. In this embodiment, the multiple mounting locations are spaced along the first path to ensure that the battery pack 5 is evenly stressed and avoid local stress concentration after connection.

[0038] Optionally, the battery pack 5 is screwed, clamped, welded or bonded to the installation area 301. In order to facilitate subsequent maintenance or better maintain the battery pack 5, it is best to use a detachable connection method such as screwing or clamping.

[0039] In some embodiments, see Figure 2 Each mounting position includes a plurality of first mounting holes 3012 spaced apart along a second path, the second path is perpendicular to the first path, and the first mounting holes 3012 are adapted to the second mounting holes at the bottom of the battery pack 5 .

[0040] After the second mounting hole at the bottom of the battery pack 5 and the first mounting hole 3012 on the mounting position are corresponded, the locking member is inserted into the first mounting hole 3012 and the second mounting hole, so as to realize the detachable connection of the battery pack 5 and the mounting position.

[0041] As another embodiment of the mounting plate 3, the mounting area 301 is further provided with a positioning column which can be in a cylindrical or block structure, and the battery pack 5 is provided with a positioning hole matched with the positioning column, and the positioning column and the positioning hole are inserted and matched. In this embodiment, the positioning is not needed when the battery pack 5 is mounted, and the positioning is directly realized after the positioning column and the positioning hole are inserted and matched, so that the correspondence of the first mounting hole 3012 and the second mounting hole is realized, and the mounting efficiency is improved.

[0042] In some embodiments, as shown in Figure 2 , the middle part of the mounting area 301 is provided with a weight-reducing hole 3011, and a plurality of mounting positions are respectively located on the two sides of the weight-reducing hole 3011 along the first path.

[0043] Since the weight of the battery pack 5 is large, after a plurality of battery packs 5 are mounted in the accommodating chamber, the weight of the entire battery pack mounting assembly is large, which affects the lightweight of the whole vehicle. The weight-reducing hole 3011 is arranged on the mounting area 301, so that the weight of the mounting plate 3 is reduced, and the mounting positions are distributed on the two sides of the weight-reducing hole 3011, so that the weight-reducing hole 3011 is uniformly stressed on the two sides, and deformation of the area of the weight-reducing hole 3011 caused by uneven stress of the mounting area 301 is avoided.

[0044] In some embodiments, as shown in Figure 2 , the fixing area 302 is distributed on the opposite two sides of the mounting area 301 along the second path, and the second path is perpendicular to the first path, and each fixing area 302 is spaced apart from a plurality of fixing positions 3022 along the first path.

[0045] Since the accommodating cavity is distributed with a plurality of accommodating cavities along the first path, if the fixing area 302 is distributed along the first path, the battery pack 5 will be affected by the adjacent battery pack 5 during dismounting and mounting, so the fixing area 302 is distributed along the second path, so that the mounting plate 3 and the support plate 2 can be conveniently separated, and the battery pack 5 can be quickly dismounted and mounted. In addition, the fixing area 302 is distributed on the opposite two sides of the mounting area 301, so that the mounting area 301 is uniformly stressed on the two sides.

[0046] In some embodiments, as shown in Figures 2 to 3 , the fixing area 302 is further provided with a weight-reducing groove 3021, and the weight-reducing groove 3021 is located between the adjacent two fixing positions 3022.

[0047] The weight-reducing groove 3021 can reduce the weight of the fixing area 302, so as to avoid that the weight of the entire battery pack mounting assembly is too large. In addition, the weight-reducing groove 3021 is arranged between the adjacent two fixing positions 3022, so that the strength of the entire fixing area 302 is uniform, and the fixing area 302 is not easy to be deformed or broken.

[0048] In some embodiments, referring to Figure 1 The support plate 2 is sequentially provided with a plurality of hollow holes 201 along the first path.

[0049] The provision of the hollow holes 201 reduces the weight of the support plate 2, and the provision of the plurality of hollow holes 201 along the first path can ensure the strength and rigidity of the support plate 2, compared with the scheme of providing only one large hollow hole 201 to reduce weight, thereby providing effective support for the battery pack 5 and reducing the probability of deformation under stress.

[0050] In some embodiments, referring to Figure 1 The mounting rack 1 comprises a support assembly and a connecting assembly. The support assembly comprises a plurality of rack bodies 101 sequentially and spacedly distributed along the up-down direction, and a mounting cavity is formed between two adjacent rack bodies 101. The connecting assembly comprises a plurality of connecting bodies 102 spacedly distributed along the first path, and the connecting bodies 102 sequentially connect the plurality of rack bodies 101 and separate the mounting cavity into a plurality of accommodation chambers along the first path.

[0051] The connecting bodies 102 provide support force for the rack bodies 101 to ensure that the mounting cavity does not deform in the up-down direction. The scheme in the present embodiment can separately prepare the rack bodies 101, the connecting bodies 102 and the partition plates during production, and then perform splicing assembly.

[0052] Optionally, the rack bodies 101 and the connecting bodies 102 are screwed or welded.

[0053] Optionally, the mounting rack 1 further comprises a plurality of partition plates connected to the connecting bodies 102, and the partition plates are provided in one-to-one correspondence with the connecting bodies 102. The partition plates are connected to the connecting bodies 102, thereby improving the support performance and avoiding the problem of deformation of the rack bodies 101 due to the increase of gravity after the installation of the battery pack 5.

[0054] As another specific implementation scheme of the mounting rack 1, referring to Figure 1 The mounting rack 1 further comprises a reinforcing member 103 connected to two adjacent connecting bodies 102.

[0055] The reinforcing member 103 and the rack body 101 are both connected to two adjacent connecting bodies 102, thereby improving the positional stability between the two adjacent connecting bodies 102.

[0056] Optionally, the reinforcing member 103 is arranged at the bottom of the support plate 2 to provide support force for the support plate 2. Alternatively, each accommodation chamber is provided with a reinforcing member 103, and the reinforcing member 103 is located at the upper portion of each accommodation chamber.

[0057] Optionally, the reinforcing member 103 is connected to two opposite corners of the accommodation chamber.

[0058] As a specific implementation of the reinforcing member 103, referring to Figure 1The reinforcing member 103 comprises a reinforcing rod 1031 and a supporting rod 1032 connected to two ends of the reinforcing rod 1031, the supporting rod 1032 is arranged at an angle with the reinforcing rod 1031, and two ends of the supporting rod 1032 are connected to the adjacent frame body 101 and the connecting body 102 respectively.

[0059] In the embodiment, the supporting rod 1032 can avoid the deformation of the position of the frame body 101 and the connecting body 102 connected to the frame body 101, and ensure the stability of the angle. The reinforcing rod 1031 supports the adjacent two connecting bodies 102 and the adjacent two frame bodies 101, and avoids the position deviation.

[0060] In some embodiments, referring to Figure 1 The battery pack mounting assembly further comprises a fixing frame 4 connected to the mounting frame 1, the fixing frame 4 comprises a fixing body 401 and a fixing flange 402 arranged at the outer edge of the fixing body 401, and the fixing flange 402 is connected to the vehicle body.

[0061] The fixing flange 402 can improve the strength and deformation resistance of the fixing frame 4 on the one hand, and can increase the contact area with the vehicle body on the other hand, thereby improving the stability and reliability of the connection.

[0062] Based on the same inventive concept, the utility model also provides a vehicle. Referring to Figure 1 The vehicle comprises the above-mentioned battery pack mounting assembly.

[0063] The vehicle provided by the utility model adopts the above-mentioned battery pack mounting assembly, the battery pack mounting assembly is connected with the battery pack 5 through the mounting plate 3, and the battery pack 5 is fixed to the mounting area 301. Since the fixing area 302 is located outside the mounting area 301, after the battery pack 5 is fixed to the mounting area 301, the fixing area 302 is still exposed to the outer plate and is not shielded by the battery pack 5. The battery module formed by the battery pack 5 and the mounting plate 3 is arranged in the accommodating chamber, and the fixing area 302 is connected to the support plate 2. In the utility model, the support plate 2 provides support force for the battery module formed by the mounting plate 3 and the battery pack 5, thereby ensuring the connection stability and reliability of the battery pack 5. In addition, since the fixing area 302 of the mounting plate 3 is exposed to the battery pack 5, the fixing area 302 can be directly separated from the support plate 2 when the battery pack 5 is disassembled. Compared with the prior art in which the bottom of the battery pack 5 is fixed to the support plate 2, the whole battery pack mounting assembly does not need to be disassembled from the vehicle body, and the battery pack 5 is disassembled from bottom to top one by one, thereby improving the disassembly convenience and work efficiency in the maintenance of the battery pack 5.

[0064] The above only describes the preferred embodiments of the utility model, and does not limit the utility model, and any modification, equivalent replacement and improvement made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
