[0002] In the existing power battery processing field, after the battery pack is assembled, it must undergo a series of performance tests to ensure its safety and reliability. These performance tests include but are not limited to battery charging and discharging performance, temperature characteristics, voltage stability, resistance testing, etc. Since different testing items require different testing equipment and instruments, in actual operation, the battery pack needs to be moved between different stations to complete all necessary tests.

[0003] However, there are some significant problems with traditional battery pack testing methods. First, at each testing station, technicians need to connect the cables on the battery pack to the corresponding testing equipment. This process usually involves a lot of wiring work, which is not only time-consuming but also prone to errors. Wiring errors or improper connections may cause battery short circuits or other electrical failures, which not only damage the equipment but also pose a threat to the safety of the operator. In addition, frequent wiring operations also reduce the efficiency of testing. Every time the testing equipment is replaced, rewiring is required, which not only increases labor costs, but also prolongs the battery pack testing cycle. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0033] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0034] There are some significant problems with traditional battery pack testing methods. First, at each testing station, technicians need to connect the cables on the battery pack to the corresponding testing equipment. This process usually involves a lot of wiring work, which is not only time-consuming but also prone to errors. Wiring errors or improper connections may cause battery short circuits or other electrical failures, which not only damage the equipment but also pose a threat to the safety of the operator. In addition, frequent wiring operations also reduce the efficiency of testing. Every time the testing equipment is replaced, rewiring is required, which not only increases labor costs, but also prolongs the battery pack testing cycle.

[0035] Based on the above-mentioned shortcomings, the utility model proposes a battery pack transport vehicle.

[0036] See also Figures 1 to 3 In one embodiment of the present utility model, the battery pack transport vehicle 100 includes:

[0037] Rack 1;

[0038] A vehicle plate 2 is provided on a side of the frame 1 away from the ground and is used for placing the battery pack;

[0039] A power connector 3, mounted on one side of the vehicle panel 2, for electrically connecting to an external testing device; and

[0040] The plug assembly 4 is disposed on the vehicle panel 2 and connects the battery pack and the power connector 3 .

[0041] In the technical solution of the utility model, the battery pack transfer cart 100 is provided with a car plate 2 on the side of the frame 1 away from the ground. When the battery pack is processed, the battery pack only needs to be placed on the car plate 2 and moved between multiple inspection stations to complete the subsequent multiple inspection tasks. A power connector 3 is installed on the car plate 2, and the plug assembly 4 on the cart is pre-connected with the power connector 3 through a cable. During the inspection, multiple cables on the battery pack are connected to the plug assembly 4 on the cart once, reducing the need for repeated wiring during the inspection process. This significantly reduces the risk of electrical accidents such as battery short circuits caused by wiring errors or accidental touches, thereby ensuring the safety of operators and the integrity of the battery pack. Since the plug assembly 4 of the battery pack on the cart is pre-connected with the power connector 3, when the battery pack needs to be moved between different inspection stations, it is only necessary to simply connect the power connector 3 on the cart to the external inspection equipment, without the need for cumbersome wiring operations, which greatly improves the efficiency of the inspection process and shortens the inspection cycle of the battery pack.

[0042] Specifically, there is no specific limitation on the type of the plug assembly 4, for example, it may include a resistance detection plug, a high and low temperature performance plug, a charge and discharge performance plug, etc., which is specifically designed according to the application scenario or vehicle model of the battery pack. In this solution, since the plug assembly 4 and the power connector 3 are fixed and designed to be easy to access and inspect, maintenance and troubleshooting become more convenient. This helps to reduce downtime and ensure the continuous operation of the test line. In addition, each battery pack only needs to be wired once during performance testing, which simplifies the wiring process, meaning that the number of technicians required at the test station can be reduced, or more battery packs can be processed with the same human resources. This directly reduces labor costs and improves the overall production capacity of the production line. In addition, the power connector 3 needs to adopt a compatible structure. No matter what type of detection equipment, as long as it is compatible with the power connector 3 on the trolley, it can be quickly connected to the battery pack, thereby improving the flexibility and adaptability of the detection line. In another embodiment, in order to facilitate the movement of the trolley, a plurality of moving wheels are arranged at intervals on the side of the frame 1 facing the ground. These moving wheels are evenly distributed at the bottom of the frame 1, so that the trolley can move smoothly on various grounds, improving the transportation efficiency.

[0043] In the embodiments of the present invention, please refer to Figure 3 The vehicle panel 2 is provided with a first plug slot 21, and the plug assembly 4 includes a first high-voltage plug 41 and a low-voltage plug 42. In order to ensure that the battery and its charging interface can work normally and safely under various conditions, high-voltage and low-voltage tests need to be performed on them, so the first high-voltage plug 41 and the low-voltage plug 42 are provided. In addition, the first high-voltage plug 41 and the low-voltage plug 42 are arranged at intervals in the first plug slot 21, and are both connected to the battery pack and the power connector 3. The setting of the first plug slot 21 allows the first high-voltage plug 41 and the low-voltage plug 42 to be easily inserted and removed. The spacing of the two plugs helps to clearly distinguish interfaces of different voltage levels, avoids connection errors caused by operator misoperation, and ensures electrical safety.

[0044] In the embodiments of the present invention, please refer to Figure 3 The battery pack is used in a vehicle. The vehicle plate 2 is provided with a second plug slot 22 arranged opposite to the first plug slot 21. The plug assembly 4 also includes a second high-voltage plug 43 arranged in the second plug slot 22. The second plug slot 22 is arranged opposite to the first plug slot 21, and can be quickly adapted according to the drive system layout of different vehicles, so that the battery pack transport vehicle 100 can adapt to more types of vehicles and enhance versatility. In addition, the first high-voltage plug 41 and the second high-voltage plug 43 are respectively connected to the front drive system and the rear drive system of the vehicle, so that the battery pack can meet the power requirements of different drive systems at the same time, support multi-drive system connection and improve the scope of application of the battery pack.

[0045] In the embodiments of the present invention, please refer to Figure 3 The plug assembly 4 also includes a boost plug 44, which is disposed in the first plug slot 21 and is spaced apart from the first high-voltage plug 41 and the low-voltage plug 42. The setting of the boost plug 44 can detect the boost charging performance of the battery pack, thereby improving the flexibility and selectivity of charging, that is, high-voltage charging, low-voltage and boost charging, and meeting the charging requirements in different scenarios. The boost plug 44 is spaced apart from other plugs, which is conducive to distinguishing from other plugs and avoiding detection errors or duplications.

[0046] In the embodiments of the present invention, please refer to Figure 3 , the plug assembly 4 also includes a fast charging plug 45, which is arranged in the first plug slot 21 and is spaced apart from the first high-voltage plug 41 and the low-voltage plug 42. The setting of the fast charging plug 45 can detect the boost charging performance of the battery pack, so that the battery pack can be charged quickly, which greatly shortens the charging time and improves the charging efficiency. The fast charging plug 45 is spaced apart from other plugs to facilitate distinction from other plugs and avoid detection errors or duplications. It should be noted that the interfaces of the multiple plugs in the plug assembly 4 should be different to facilitate distinction.

[0047] In the embodiments of the present invention, please refer to Figure 2 The power connector 3 includes a plug board 31, which is arranged on one side of the vehicle panel 2 and is electrically connected to the plug assembly 4. The plug board 31 is provided with a plurality of plug holes 32, which are used to electrically connect to the plug of the external detection equipment. The plug board 31 is provided with a plurality of plug holes 32, which can meet the power connection requirements of different types at the same time. During the battery pack detection process, there is no need to frequently repeat the wiring connection. The connection can be completed by simply inserting the plug of the external detection equipment into the corresponding plug hole 32, which greatly simplifies the operation process. Since the plug hole 32 can quickly connect the external detection equipment, the battery pack detection process is more efficient. The operator can complete multiple detection items in a short time, shortening the battery pack detection cycle and improving production efficiency.

[0048] In the embodiments of the present invention, please refer to Figure 1 and Figure 3 The battery pack transport trolley 100 also includes a support plate 5, which is disposed on the side of the vehicle plate 2 facing away from the ground. The support plate 5 provides a certain buffer between the battery pack and the vehicle plate 2, reducing the physical impact that the battery pack may receive during transportation and protecting the battery pack from unnecessary damage. In addition, the support plate 5 is arranged to protrude from the surface of the vehicle plate 2, so that the support plate 5 can be used as a positioning point to help operators or various handling tools (such as manual or electric transport vehicles) to more easily place or remove the battery pack, thereby improving efficiency.

[0049] In the embodiments of the present invention, please refer to Figure 1 and Figure 3 , the side of the vehicle plate 2 facing away from the ground is coated with an insulating layer, which ensures that any contact between the battery pack and the vehicle plate 2 during transportation and testing will not cause short circuits or other electrical problems. The presence of the insulating layer significantly improves the safety of the operator and the safety of the battery pack. Optionally, the support plate 5 is made of insulating material to avoid electrical contact between the battery pack and the support plate 5, further enhancing the electrical safety of the entire transfer cart. The insulating material can also effectively prevent current leakage, for example, it can be plastic, rubber or ceramic. Optionally, a plurality of support plates 5 are evenly spaced on the vehicle plate 2. Such a design can improve the carrying capacity and stability of the vehicle plate 2. The evenly distributed support plates 5 help to disperse and buffer the weight of the battery pack and reduce deformation or damage of the vehicle plate 2 due to excessive local pressure.

[0050] In the embodiments of the present invention, please refer to Figure 1 , Figure 3 and Figure 4 The vehicle plate 2 is provided with a guide block 23, which is protruding from the surface of the vehicle plate 2. The existence of the guide block 23 ensures that the battery pack can be accurately positioned in a preset direction when placed, thereby improving the accuracy of placement. Since the guide block 23 provides clear visual and physical indications, the operator can easily slide the battery pack along the guide block 23 until the battery pack is stably placed on the support plate 5. In addition, the design of the guide block 23 helps prevent the battery pack from tilting or tipping over during placement, thereby reducing the risk of damage to the battery pack and ensuring the safety of the operator.

[0051] In the embodiments of the present invention, please refer to Figure 1 , Figure 3 and Figure 4 A plurality of guide blocks 23 are arranged at intervals, and the plurality of guide blocks 23 are arranged along the length direction of the vehicle plate 2 and are arranged on opposite sides of the support plate 5. The uniform distribution of the plurality of guide blocks 23 along the placement direction of the battery pack can guide the placement of the battery pack and limit the lateral movement of the battery pack on the vehicle plate 2. In addition, a plurality of guide blocks 23 for limiting can be arranged at the tail of the battery pack placed on the vehicle plate 2 to limit the placement end of the battery pack and avoid excessive placement of the battery pack.

[0052] In the embodiments of the present invention, please refer to Figure 5The vehicle plate 2 is also provided with a positioning member 24. The positioning member 24 is provided on the side of the vehicle plate 2 facing the ground. The positioning member 24 is used to lock the position of the battery pack transfer cart 100, so that it is locked at the position of the detection station, ensuring that the position of the cart remains fixed during the entire detection process. Optionally, the positioning member 24 can be a positioning hole. When positioning is required, a locking member can be used to pass through the positioning hole on the vehicle plate and lock the structure at the detection station to achieve the connection and fixation of the cart to the detection station. During the detection process, the transfer cart may be affected by external forces, such as human push, vibration on the production line, etc. The presence of the positioning member 24 can resist these external forces, maintain the stability of the cart, and avoid interruption of the battery pack connection or other accidents caused by the movement of the cart.

[0053] In the embodiments of the present invention, please refer to Figures 1 to 4 The vehicle plate 2 is provided with a limit seat 25, which is protruding from the surface of the vehicle plate 2 to position the battery pack at the target position on the vehicle plate 2. The limit seat 25 may include a limit plate and a positioning pin. The placement position of the battery pack can be changed by adjusting the position of the positioning pin on the limit plate, ensuring that the battery pack can be quickly and accurately positioned at the predetermined position each time it is placed on the vehicle plate 2. This reduces connection errors caused by improper positioning of the battery pack and improves the reliability of the detection process. In addition, under the constraint of the limit seat 25, the battery pack can remain stable even during transportation, reducing the risk of accidental movement of the battery pack on the vehicle plate 2.

[0054] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
