[0003] Currently, when disassembling the battery swapping tray, it is placed on the ground, which causes scratches and dirt on the surface of the parts. At the same time, the frequent handling of disassembled parts and changing their positions results in extremely low disassembly efficiency and high labor intensity for employees. Disassembling on the ground also poses a safety hazard of bumps and injuries. After the assembly is completed, the high-voltage wiring harness of the charging port interferes with the ground, making it impossible to directly perform installation verification.

[0004] A battery tray disassembly and testing stand is proposed to address the problems mentioned above. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a battery base tray disassembly and testing stand, including a support frame;

[0007] The top of the support frame is provided with an upper bracket;

[0008] Also includes:

[0009] The top of the upper bracket is symmetrically provided with longitudinal beams, and several cross beams are fixedly installed between the two longitudinal beams. The top of the two longitudinal beams is fixedly installed with a battery swapping base. A solenoid valve is fixedly installed on one side of the upper bracket. Air pipes are provided inside and outside the upper bracket, and one end of the air pipes is connected through the solenoid valve.

[0010] Among them, several limiting frames are symmetrically installed on both sides of the upper bracket, and the air pipe is connected to the limiting frames through the air pipe. Several positioning frames are symmetrically installed on both sides of the upper bracket above the several limiting frames. Two sets of positioning holes are opened through the two longitudinal beams on the side close to the several positioning frames.

[0011] The battery swapping base is equipped with a battery swapping base inspection tool on its top, and two sets of lifting rings are symmetrically installed on the top of the battery swapping base inspection tool.

[0012] Preferably, each of the positioning frames has two sets of mounting holes through one side, and the mounting holes correspond to the positioning holes.

[0013] Preferably, the lower outer side of the battery swapping base inspection tool has several circular holes.

[0014] Preferably, two sets of connecting frames are symmetrically installed inside the battery swapping base, and cylinders are fixedly installed on one side of several connecting frames inside the battery swapping base, and several air pipes pass through the upper bracket and are connected to several cylinders.

[0015] Preferably, each of the moving ends of the cylinders is fixedly equipped with a connecting rod, and a locking tongue is fixedly installed at the end of the connecting rod away from the cylinder.

[0016] Preferably, a fixing plate is symmetrically installed on the upper part of the center of the battery swapping base, and an mounting plate is provided above the two fixing plates. A charging port and a discharging port are symmetrically provided on the top of the mounting plate. Two sets of support rods are symmetrically installed on both sides of the inside of the mounting plate. The support rods are slidably connected to the fixing plates.

One end of the telescopic spring is fixedly connected to the mounting plate, and the other end of the telescopic spring is fixedly connected to the fixing plate.

[0017] Preferably, the upper bracket and the support frame are connected by bolts for disassembly.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: This battery base tray assembly and testing stand, through an integrated assembly and testing fixture, allows welded parts to be placed on the fixture stand, securely fixed, and without safety risks. At the same time, it significantly improves quality and assembly efficiency. After assembly, it can be directly subjected to unloading and matching verification without secondary relocation, thus ensuring safety, quality, efficiency, and space utilization. The specific details are as follows:

[0019] 1. When placing the battery swapping base, the longitudinal beam is placed on the upper bracket. Before placing it, it's crucial to verify that the width of the longitudinal beam on both sides matches the width of the positioning brackets on both sides of the tooling, ensuring proper placement. Secondly, it's necessary to check if the positioning holes and mounting holes on both sides of the longitudinal beam coincide, and to inspect the hole positions and spacing for compliance. Then, the base components are assembled, significantly improving assembly efficiency and avoiding repetitive bending to retrieve parts. This greatly enhances the overall assembly efficiency of the battery swapping base, ensuring safety and reliability. The welded components of the base are assembled on a platform, effectively preventing personnel from bumping into or tripping over objects. Verification accuracy and efficiency are significantly improved. Previously, it was impossible to inspect the fit between the battery swapping base and the vehicle frame, and between the battery and the base, before installation. Due to product inconsistency, assembly abnormalities occurred multiple times during installation, resulting in repeated assembly and disassembly, which wasted a lot of manpower and resources. Now, with the use of workbenches and inspection tools, the product qualification can be efficiently and accurately inspected before installation, which greatly reduces costs and further improves the appearance quality. Previously, the welding parts of the base were placed on the ground for sub-assembly, which caused scratches and dirt on the surface of the welding parts and other loose parts, affecting the appearance quality of the assembly. Now, with the sub-assembly workbench, paint scratches, paint chipping, and surface dirt can be effectively avoided.

[0020] 2. After the assembly is completed, connect the air / power supply. By operating the solenoid valve and pressing its control switch, the cylinder can move the connecting rod under the action of the air supply, which in turn moves the locking tongue, allowing the battery box assembly to be smoothly hoisted onto the battery swapping base from directly above. This allows the cylinder to move and confirms the locking tongue's travel. Then, the battery swapping base inspection fixture is hoisted onto the battery swapping base, ensuring the locking tongue is in the retracted state. The fixture is then lowered, and its placement is checked. Next, the locking tongue is checked to ensure it does not interfere with the fixture or is not fully extended; otherwise, it is considered unqualified. During the descent of the fixture, the mounting plate can slide on the support rod, allowing the compression spring to be compressed. The high-voltage line of the charging port on the battery swapping base has a recessed area, placed on two longitudinal beams, which effectively avoids damage to the high-voltage wiring harness and makes the locking tongue extension range more visually apparent.

[0027] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 This utility model provides a technical solution: a battery bottom tray disassembly and testing platform, including a support frame 1, an upper bracket 101 on the top of the support frame 1, and further including: longitudinal beams 102 symmetrically arranged on the top of the upper bracket 101, with several crossbeams fixedly installed between the two longitudinal beams 102, and a battery swapping bottom tray 103 fixedly installed on the top of the two longitudinal beams 102; a solenoid valve 104 fixedly installed on one side of the upper bracket 101; and air pipes 105 arranged inside and outside the upper bracket 101, with one end of the air pipe 105 connected through to the solenoid valve 104. Several limiting frames 106 are symmetrically installed on both sides of the upper bracket 101, and the air pipes 105 are connected through to the limiting frames 106. Furthermore, several positioning frames 107 are symmetrically installed on both sides of the upper bracket 101 above several limiting frames 106. Two sets of positioning holes 108 are also provided on the side of the two longitudinal beams 102 near the positioning frames 107. The top of the battery swapping base 103 is provided with a battery swapping base inspection tool 109, and two sets of lifting rings 110 are symmetrically installed on the top of the battery swapping base inspection tool 109. Through the integrated assembly and inspection tooling table, the welded parts can be placed on the tooling table and fixed firmly without any safety risks. At the same time, the quality level and assembly efficiency are significantly improved. After the assembly is completed, the unloading and matching verification can be carried out directly without the need for secondary relocation. This ensures safety, quality, efficiency, and space utilization.

[0029] Each of the positioning brackets 107 has two sets of mounting holes through one side, and the mounting holes correspond to the positioning holes 108, which can be used to check whether the battery swapping base 103 is properly placed. The lower outer side of the battery swapping base inspection fixture 109 has several circular holes 111 through it, and six circular holes 111 around it, simulating the external holes of the power battery, allowing for precise inspection of the assembly tolerances and fit between the two. Two sets of connecting brackets 112 are symmetrically installed inside the battery swapping base 103, and cylinders 113 are fixedly installed on one side of each of the connecting brackets 112 inside the battery swapping base 103. Several air pipes on the air pipeline 105 pass through the upper bracket 101 and are connected to the cylinders 113, allowing the cylinders 113 to operate. Connecting rods 114 are fixedly installed on the movable ends of the cylinders 113, and a lock is fixedly installed on the end of the connecting rod 114 away from the cylinder 113. Tongue 115 facilitates the detection of whether the battery swapping base tray gauge 109 interferes with the locking mechanism. A fixing plate 116 is symmetrically installed above the center of the battery swapping base tray 103, and a mounting plate 117 is provided above the two fixing plates 116. A charging port and a discharging port are symmetrically arranged on the top of the mounting plate 117. Two sets of support rods 118 are symmetrically installed on both sides of the inside of the mounting plate 117, and the support rods 118 are slidably connected to the fixing plates 116. A telescopic spring 119 is sleeved on the outside of the support rods 118, with one end of the telescopic spring 119 fixedly connected to the mounting plate 117 and the other end fixedly connected to the fixing plate 116. The high-voltage line of the charging port of the battery swapping base tray 103 has a recessed area, resting on two longitudinal beams 102, which effectively prevents damage to the high-voltage line harness. The upper bracket 101 and the support frame 1 are connected by bolts for easy fixing and disassembly.

[0030] Working principle: Before using this type of battery tray disassembly and testing stand, it is necessary to check the overall condition of the device to ensure that it can operate normally. Figure 1 - Figure 5 As shown, when placing the battery swapping base 103, the longitudinal beam 102 is placed on the upper bracket 101. Before placing it on the upper bracket 101, it can be verified whether the width of the two sides of the longitudinal beam 102 is consistent with the width of the positioning brackets 107 on both sides of the tooling, and whether it can be placed normally. Secondly, it can be checked whether the positioning holes 108 on both sides of the longitudinal beam 102 coincide with the mounting holes, and the hole positions and hole spacing can be checked to see if they are qualified. Then, the base parts are assembled. The assembly process does not require bending over, which greatly reduces the labor intensity of employees during the assembly process. At the same time, the assembly efficiency is further improved, and there is no need to frequently pick up, remove, or change positions of parts.

[0031] After the assembly is completed, the air / power supply is connected. By operating the solenoid valve 104 and pressing its control switch, the cylinder 113, under the action of the air supply, can move the connecting rod 114, which in turn moves the locking tongue 115, allowing the battery pack assembly to be smoothly hoisted onto the battery swapping base 103 from directly above. This causes the cylinder 113 to move, confirming the stroke of the locking tongue 115. Then, the battery swapping base inspection fixture 109 is lowered onto the battery swapping base 103, ensuring the locking tongue 115 is in the retracted state. The battery swapping base inspection fixture 109 is then lowered. Next, check whether the battery swapping base tray gauge 109 is in place. Then check whether the latch 115 extends and interferes with the battery swapping base tray gauge 109 or whether the latch 115 extends incompletely. If so, it will be deemed unqualified; otherwise, it will be qualified. During the descent of the battery swapping base tray gauge 109, the mounting plate 117 can slide on the support rod 118, which can compress the telescopic spring 119. The high-voltage line of the charging port of the battery swapping base tray 103 has a sunken area, which is placed on the two longitudinal beams 102. This can effectively avoid damage to the high-voltage line harness, and when checking the extension range of the latch 115, it is more intuitive to see.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
