[0002] A battery box is a carrier for battery modules of new energy vehicles, and its design and material selection have an important impact on the safety and performance of the battery. The design of the battery box takes into account various factors, including the connection of battery modules, waterproof and dustproof, and the ability to withstand vibrations and impacts during vehicle operation. In addition, the material of the battery box has gradually changed from traditional steel to aluminum alloy to achieve vehicle lightweighting and improve energy use efficiency. Since the battery modules in the battery box need to be isolated, each side plate of the battery box needs to be covered with a film to ensure no leakage and no conductivity between the battery modules. After the side plate of the battery box is covered with a film, a voltage resistance test needs to be carried out. The existing voltage resistance test is carried out manually. The operator clamps the wiring clip of the voltage resistance tester at the end of the side plate and uses a voltage resistance test rod to test the film-covered surface of the side plate to detect whether the film-covered surface of the side plate is leaking electricity or conducting electricity. Manual testing has low operating safety and low testing efficiency.

[0003] For example, Chinese Patent Publication No. CN217321580U, Publication Date August 30, 2022, titled "An Automobile Battery Box Packaging Structure", includes a box body, a bottom plate, two end plates, two side plate assemblies, and a plurality of positioning strips.

[0004] The disadvantages of existing patents are: after the side plates of the existing battery box are covered with a film, manual voltage resistance tests are carried out on the side plates one by one, and manual testing has low operating safety and low testing efficiency. Summary of the Utility Model

The baffle levels the ends of the side plates placed on the bracket. The pressing plate is pressed on the side plate, and the side plate is pressed on the bracket through the pressing plate.

The withstand voltage detector includes a wiring clip for clamping the end of the side plate and a withstand voltage test rod for detecting the withstand voltage of the film-covered surface of the side plate, which are connected by a wire. The wiring clip clamps the end of the side plate, and the end of the side plate is not covered with a film. The withstand voltage test rod detects the film-covered surface of the side plate to check whether the film-covered surface of the side plate leaks electricity or conducts electricity. One end of the side plate is leveled by the baffle, and the other end is electrically connected to the wiring clip. The withstand voltage of the film-covered surface of the side plate is tested by the withstand voltage test rod.

[0008] Preferably, the bracket includes at least two support blocks, and the support blocks are arranged on the detection platform and support both ends of the side plate. There are several brackets arranged in parallel along the width direction of the detection platform on the detection platform.

[0028] To make the objectives, technical solutions and advantages of the technical solution embodiments of the present utility model clearer, the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0029] Embodiment 1, as Figure 1 , Figure 2A pressure resistance testing device for the side plate of a battery box is shown, which includes a detection platform 1 and a pressure resistance detector 2. A number of parallel brackets 3 are provided on the detection platform 1. A pressing plate 4 for pressing the side plate 11 on each bracket 3 is provided on the bracket 3. A baffle 5 for leveling the ends of the side plates 11 is provided on the detection platform 1. The pressure resistance detector 2 includes a wiring clip 2.1 for clamping the end of the side plate 11 and a pressure resistance test rod 2.2 for detecting the pressure resistance of the film-covered surface of the side plate 11. The baffle 5 and the wiring clip 2.1 are respectively located at both ends of the detection platform 1.

[0030] The battery box is the carrier of the battery module of new energy vehicles, and its design and material selection have an important impact on the safety and performance of the battery. The design of the battery box takes into account various factors, including the connection of battery modules, waterproof and dustproof, and the ability to withstand vibration and impact during vehicle operation. In addition, the material of the battery box has gradually changed from traditional steel to aluminum alloy to achieve vehicle lightweighting and improve energy use efficiency. Since it is necessary to isolate the battery modules in the battery box, it is necessary to film each side plate 11 of the battery box to ensure that there is no leakage or conduction between the battery modules. After the side plate 11 of the battery box is filmed, a pressure resistance test is required. The existing pressure resistance test is carried out manually. The operator clamps the wiring clip 2.1 of the pressure resistance tester at the end of the side plate 11 and uses the pressure resistance test rod 2.2 to test the film-covered surface of the side plate 11 to detect whether the film-covered surface of the side plate 11 is leaking or conducting. Manual testing has relatively low operating safety and low testing efficiency.

[0031] In order to solve the problems of low safety and low test efficiency in the manual pressure resistance test of each side plate 11 of the existing battery box after film covering, a pressure resistance test device for the side plate 11 of the battery box is provided, which improves the operation safety and the test efficiency. In a pressure resistance test device for the side plate of the battery box in this embodiment, the side plate 11 is placed on the bracket 3, and the brackets 3 are arranged in parallel. The end parts of the baffles 5 placed on the brackets 3 are flush. The pressing plate 4 is pressed on the side plate 11, and the side plate 11 is pressed on the bracket 3 through the pressing plate 4. The pressing plate 4 prevents the side plate 11 from moving or tilting, and prevents collision between the side plates 11. The pressure resistance detector 2 includes a wiring clip 2.1 for clamping the end part of the side plate 11 connected by a wire and a pressure resistance test rod 2.2 for detecting the film-covered surface of the side plate 11. The wiring clip 2.1 clamps the end part of the side plate 11, and the end part of the side plate 11 is not film-covered. The pressure resistance test rod 2.2 detects the film-covered surface of the side plate 11 to detect whether the film-covered surface of the side plate 11 is leaking electricity or conducting electricity. One end of the side plate 11 is flush through the baffle 5, and the other end is electrically connected to the wiring clip 2.1. The film-covered surface of the side plate 11 is tested through the pressure resistance test rod 2.2. The side plates 11 are placed on the detection platform 1 in batches and then measured, improving the detection efficiency. Through the cooperation of the bracket 3 and the pressing plate 4, the side plate 11 is prevented from moving and turning up, and any surface of the side plate 11 can be detected, improving the safety of the detection operation after the side plate 11 is electrically connected. Multiple side plates 11 are detected at the same time, and multiple wiring clips 2.1 are electrically connected to multiple side plates 11 at the same time, reducing the start-stop operation of the pressure resistance detector 2 and further improving the detection efficiency.

[0032] The bracket 3 is further optimized, as Figure 1 , Figure 2 shown. The bracket 3 includes at least two support blocks, and the support blocks are arranged on the detection platform 1 and support the two ends of the side plate 11. A number of brackets 3 are arranged on the detection platform 1 in parallel along the width direction of the detection platform 1. The brackets 3 extend along the length direction of the detection platform 1. The support blocks in any one of the brackets 3 are distributed along the length direction of the detection platform 1, so that the side plates 11 are arranged in parallel along the width direction of the detection platform 1 and extend along the length direction of the side plate 11.

[0033] The pressing plate 4 is further optimized, as Figure 1 shown. The pressing plates 4 correspond to the brackets 3 one by one, and the pressing plates 4 are connected through the connecting plate 6. A handle 7 is arranged on the connecting plate 6. Thus, the pressing plates 4 pressed on each side plate 11 can be pressed above the side plate 11 at the same time, and the pressing plates 4 are lifted and lowered through the handle 7. The number of the connecting plates 6 is two, and the two connecting plates 6 are respectively located at the two ends of the pressing plate 4. The connection stability of each pressing plate 4 is improved, and the two handles 7 are located at the two ends of the pressing plate 4, which is convenient for operation.

[0034] Specifically, as Figure 1As shown, a spacer block 8 is provided between the pressing plate 4 and the connecting plate 6. A rib extending along the length direction of the side plate 11 is provided on the side plate 11, and the spacer block 8 prevents collision between the connecting plate 6 and the side plate 11. An avoidance groove for avoiding the rib of the side plate 11 is provided on the bracket 3, and the avoidance groove extends along the length direction of the bracket 3. The avoidance groove also has a positioning function, so that the position where the side plate 11 is placed on the bracket 3 is limited.

[0035] The above embodiment has the following beneficial effects: The side plate 11 is pressed on the bracket 3 by the pressing plate 4. The pressing plate 4 prevents the side plate 11 from moving or tilting, and prevents collision between the side plates 11. The side plates 11 are placed on the detection platform 1 in batches and then measured, improving the detection efficiency. Through the cooperation of the bracket 3 and the pressing plate 4, the side plate 11 is prevented from moving and turning up, and any side of the side plate 11 can be detected, improving the safety of the detection operation after the side plates 11 are electrically connected. At the same time, multiple side plates 11 are detected, and multiple wiring clips 2.1 are electrically connected to multiple side plates 11 at the same time, reducing the start-stop operation of the withstand voltage detector 2 and further improving the detection efficiency.

[0036] Embodiment 2, as Figure 3 shown, a battery box side plate withstand voltage test device includes a detection platform 1 and a withstand voltage detector 2. A plurality of parallel brackets 3 are provided on the detection platform 1. A pressing plate 4 for pressing the side plate 11 on each bracket 3 is provided on the bracket 3. A baffle 5 for leveling the ends of the side plates 11 is provided on the detection platform 1. The withstand voltage detector 2 includes a wiring clip 2.1 for clamping the end of the side plate 11 and a withstand voltage test rod 2.2 for detecting the film-covered surface of the side plate 11. The baffle 5 and the wiring clip 2.1 are respectively located at both ends of the detection platform 1.

[0037] In this embodiment, as Figure 3 shown, a storage platform 9 is provided below the detection platform 1. The detection platform 1 is supported above the storage platform 9 by support columns. The withstand voltage detector 2 is located on the storage platform 9. The storage platform 9 is used for storing the withstand voltage tester. The withstand voltage tester is placed below the detection platform 1 and is electrically connected to the wiring clip 2.1 through a wire. The wiring clip 2.1 is electrically connected to the end of the side plate 11, so that the withstand voltage test of the side plate 11 can be centrally completed on the withstand voltage test device of the present technical solution.

[0038] Further optimize the detection platform 1, as Figure 3As shown, the withstand voltage detector 2 is connected to the terminal clamp 2.1 through a wire. A card slot 1.1 for clamping the wire is provided at the edge of the detection platform 1. The card slots 1.1 correspond to the brackets 3 one by one. The card slots 1.1 and the baffle 5 are located at both ends of the detection platform 1 respectively. The wire is clamped and threaded through the card slot 1.1. The card slot 1.1 has a limiting and guiding function. Since multiple side plates 11 need to be detected simultaneously, the withstand voltage detector 2 is connected to multiple terminal clamps 2.1, and the wires of the multiple terminal clamps 2.1 are prone to entanglement, resulting in wire damage and inconvenient operation. Therefore, the terminal clamp 2.1 is limited by the card slot 1.1, and the terminal clamp 2.1 is limited to the edge of the detection platform 1 through the card slot 1.1, which is convenient for taking, storing and operating.

[0039] Further, as Figure 3 shown, a rubber sleeve 10 is clamped in the card slot 1.1, and the wire is threaded through the rubber sleeve 10. The rubber sleeve 10 prevents the wire from being worn and prevents jamming between the terminal clamp 2.1 and the card slot 1.1. The rubber sleeve 10 is clamped in the card slot 1.1. A notch for clamping the wire is provided on the side wall of the rubber sleeve 10. A limiting protrusion is provided at the end of the rubber sleeve 10. The limiting protrusion cooperates with the end face of the detection platform 1 to limit the rubber sleeve 10 on the card slot 1.1.

[0040] Further, as Figure 3 shown, an installation slot 9.1 is provided on the storage platform 9, and a heat dissipation port 9.2 is provided at the bottom of the installation slot 9.1. The installation slot 9.1 cooperates with the withstand voltage tester. The withstand voltage tester is placed in the installation slot 9.1, and the heat dissipation port 9.2 dissipates heat from the bottom of the withstand voltage tester. A limiting member 9.3 for storing the withstand voltage detection rod is provided on the storage platform 9. One end of the limiting member 9.3 is rotatably provided on the storage platform 9, and the other end is locked on the storage platform 9 through a bolt. The limiting member 9.3 is used to store the withstand voltage detection rod 2.2, so that the withstand voltage detection rod 2.2 can be stored on the storage platform 9, and the withstand voltage detection rod 2.2 can be stored well after the test is completed.

[0041] Alternative solution, the limiting member 9.3 is a limiting belt. One end of the limiting belt is fixed on the storage platform 9, and the other end is adhered to the storage platform 9 through a magic tape.

[0042] A voltage withstand test device for the side plate 11 of a battery box in the above embodiments places the side plate 11 on the bracket 3. The brackets 3 are arranged in parallel, and the end of the baffle 5 placed on the bracket 3 is flush. The pressing plate 4 is pressed on the side plate 11, and the side plate 11 is pressed on the bracket 3 through the pressing plate 4. The pressing plate 4 prevents the side plate 11 from moving or warping and prevents collisions between the side plates 11. The voltage withstand detector 2 includes a wiring clip 2.1 for clamping the end of the side plate 11 connected by a wire and a voltage withstand test rod 2.2 for detecting the film-covered surface of the side plate 11. The wiring clip 2.1 clamps the end of the side plate 11, and the end of the side plate 11 is not covered with a film. The voltage withstand test rod 2.2 detects the film-covered surface of the side plate 11 to check whether the film-covered surface of the side plate 11 is leaking electricity or conducting electricity. One end of the side plate 11 is flush through the baffle 5, and the other end is electrically connected to the wiring clip 2.1. The film-covered surface of the side plate 11 is tested through the voltage withstand test rod 2.2. The side plates 11 are placed on the detection platform 1 in batches and then measured, improving the detection efficiency. Through the cooperation of the bracket 3 and the pressing plate 4, the side plate 11 is prevented from moving and turning up, and any side of the side plate 11 can be detected, improving the safety of the detection operation after the side plate 11 is electrically connected. Multiple side plates 11 are detected simultaneously, and multiple wiring clips 2.1 are electrically connected to multiple side plates 11 at the same time, reducing the start-stop operation of the voltage withstand detector 2 and further improving the detection efficiency.

[0043] Further optimize the bracket 3, such as Figure 3 As shown, the bracket 3 includes at least two support blocks. The support blocks are arranged on the detection platform 1 and support both ends of the side plate 11. There are several brackets 3 arranged in parallel along the width direction of the detection platform 1 on the detection platform 1. The brackets 3 extend along the length direction of the detection platform 1. The support blocks in any one of the brackets 3 are distributed along the length direction of the detection platform 1, so that the side plates 11 are arranged in parallel along the width direction of the detection platform 1 and extend along the length direction of the side plate 11.

[0044] Further optimize the pressing plate 4, such as Figure 3 As shown, the pressing plate 4 corresponds to the bracket 3 one by one. Each pressing plate 4 is connected by a connecting plate 6, and a handle 7 is arranged on the connecting plate 6. So that the pressing plates 4 pressed on each side plate 11 can be pressed above the side plate 11 at the same time, and the pressing plate 4 is lifted and lowered through the handle 7. The number of the connecting plates 6 is two, and the two connecting plates 6 are respectively located at both ends of the pressing plate 4. The connection stability of each pressing plate 4 is improved, and the two handles 7 are located at both ends of the pressing plate 4, which is convenient for operation.

[0045] Specifically, as Figure 3 shown, a heightening block 8 is arranged between the pressing plate 4 and the connecting plate 6. There are convex ribs extending along the length direction of the side plate 11 on the side plate 11. The heightening block 8 prevents collisions between the connecting plate 6 and the side plate 11. There is an avoidance groove on the bracket 3 for avoiding the convex ribs of the side plate 11, and the avoidance groove extends along the length direction of the bracket 3. The avoidance groove also has a positioning function, limiting the placement position of the side plate 11 on the bracket 3.

[0046] The present embodiment has the following beneficial effects: The side plate 11 is pressed on the bracket 3 by the pressing plate 4. The pressing plate 4 prevents the side plate 11 from moving or tilting, and prevents collisions between the side plates 11. Placing the side plates 11 on the detection platform 1 in batches and then measuring improves the detection efficiency. Through the cooperation of the bracket 3 and the pressing plate 4, the side plate 11 is prevented from moving and turning up, and any side of the side plate 11 can be detected, which improves the safety of the detection operation after the side plates 11 are electrically connected. Multiple side plates 11 are detected simultaneously, and multiple wiring clips 2.1 are electrically connected to multiple side plates 11 at the same time, reducing the start-stop operation of the withstand voltage detector 2 and further improving the detection efficiency; convenient storage and improved operation efficiency.
