For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] As described in the background technology, a qualified battery often requires a lot of tests before it can be installed on a vehicle and put on the market. These tests are often conducted based on the use of the car in different scenarios, and usually require tests at different temperatures. Test equipment that can change the temperature will generate wind, but the actual battery is shielded and protected by the car body when in use and is not directly exposed to wind. Therefore, in the prior art, when conducting temperature tests, the battery pack is often covered with wooden boxes or other coverings to reduce the impact of wind on the test results. However, using this method of covering the battery pack means that only one battery pack can be tested at a time, resulting in low test efficiency.

[0036] Based on this, please refer to Figure 1-Figure 3 The embodiment of the utility model provides a windproof test device 100, which can effectively improve the above-mentioned technical problems, that is, it can test multiple battery packs at the same time, and the test efficiency is high. The windproof test device 100 will be described in detail below.

[0037] Please refer to Figure 1 and Figure 2 , Figure 1The schematic diagram of the structure of the windproof test device 100 provided in this embodiment is as follows: Figure 2 A partial structural diagram of the windproof test device 100 provided in this embodiment, combined with Figure 1 and Figure 2 The windproof test device 100 includes at least three stacked support units 10 and at least two windproof panels 20. The space between two adjacent support units 10 is used to accommodate the battery pack. The circumference of any two adjacent support units 10 is surrounded by windproof panels 20. The windproof panels 20 and the two adjacent support units 10 together form a closed space 30 to enclose the battery pack accommodated therein. In other words, multiple battery packs can be placed at the same time through the stacked support units 10, and each battery pack is in the closed space 30 through the enclosure of the windproof panels 20, thereby protecting the battery pack from wind. Therefore, the windproof test device 100 can test multiple battery packs at the same time, thereby improving the test efficiency.

[0038] like Figure 2 As shown, it is understandable that Figure 2 What is shown is a schematic diagram of two stacked support units 10, where the battery pack is accommodated between the two support units 10, and a windproof enclosure 20 is arranged around the circumference of the two support units 10 to form a closed space 30, which can enclose the battery pack to form a windproof effect, thereby reducing the impact of wind on the test results when the battery pack is subsequently tested.

[0039] Combination Figure 1 and Figure 2 It should be noted that, in the present embodiment, the number of the support units 10 is three, the number of the windproof panels 20 is two, the three support units 10 are stacked, and the two windproof panels 20 are respectively arranged around the circumference of two adjacent support units 10, thereby forming two closed spaces 30 together. It is easy to understand that the two closed spaces 30 can accommodate two battery packs, so that the two battery packs can be tested at the same time, thereby improving the test efficiency.

[0040] In addition, it should be pointed out that, taking the three support units 10 provided in the present embodiment as an example, the order of placing the two battery packs is as follows: first, the first support unit 10 is set on the experimental platform or the ground, and then the first battery pack is placed on the first support unit 10; then the second support unit 10 is stacked on the first support unit 10, and then the first windproof panel 20 is arranged around the first and second support units 10; then the second battery pack is placed on the second support unit 10, and then the third support unit 10 is stacked on the second support unit 10, and then the second windproof panel 20 is arranged around the second and third support units 10, thereby achieving the closure of the two battery packs.

[0041] Of course, in some other embodiments, the number of the support units 10 can also be four, five or six, etc., so that the number of the windproof panels 20 is also correspondingly three, four or five, etc., so as to implement the detection test of different numbers of battery packs. In other words, the number of the support units 10 and the windproof panels 20 needs to be determined according to different test conditions.

[0042] Please continue to combine Figure 1 and Figure 2 Specifically, the support unit 10 includes a load-bearing plate 11 and a support column 12 arranged on the load-bearing plate 11. For two adjacent stacked support units 10, the load-bearing plates 11 of the two support units 10 are spaced apart to accommodate the battery pack, and the support column 12 of the support unit 10 located on the upper layer is connected to the load-bearing plate 11 of the support unit 10 on the lower layer; wherein, a windproof enclosure 20 is arranged circumferentially around the two spaced-apart load-bearing plates 11, and a closed space 30 formed between the two load-bearing plates 11 and the windproof enclosure 20 is used to enclose the battery pack accommodated therein.

[0043] That is, when conducting the detection test, the battery pack is placed between two adjacent load-bearing plates 11, one of the load-bearing plates 11 provides load-bearing support for the battery pack, while the other load-bearing plate 11 provides load-bearing support for the other battery pack. Of course, the load-bearing plate 11 located at the top plays a role similar to a cover plate, and together with the windproof enclosure 20, it seals the battery pack; at the same time, through the setting of the support column 12, it can support the two adjacent load-bearing plates 11, so that the two adjacent load-bearing plates 11 are firmly connected; in addition, the support column 12 located at the bottom can also support the entire device.

[0044] It should be noted that, in this embodiment, the shape of the load-bearing plate 11 is rectangular, and the number of support columns 12 of each support unit 10 is four, and the four support columns 12 are respectively arranged at the four corners of the load-bearing plate 11, so as to achieve a stable connection and support function. Of course, in some other embodiments, the shape of the load-bearing plate 11 can also be a triangle, a trapezoid or a circle, etc., as long as it can achieve the function of bearing weight and cooperating with the support columns 12; and the number of support columns 12 can also be two, three or five, etc., as long as it can achieve the function of supporting the load-bearing plate 11.

[0045] Please continue to combine Figure 2Furthermore, in order to facilitate the installation of the support column 12 and the load-bearing plate 11, a first threaded hole 111 is provided at the top and bottom of each load-bearing plate 11, and the first threaded hole 111 is used to cooperate with the support column 12. In other words, the support column 12 can be provided at the top and bottom of the load-bearing plate 11, which can facilitate the stacking connection of multiple support units 10, that is, after the support column 12 of one support unit 10 is fixed to the load-bearing plate 11 by the first threaded connection, the load-bearing plate 11 can be fixed to the support column 12 of another support unit 10 by threaded connection, which facilitates the disassembly and installation of the entire stacking process and improves the assembly efficiency.

[0046] In the actual assembly process, since the load-bearing plate 11 has a certain weight, in order to facilitate transportation and installation, in this embodiment, the windproof test device 100 also includes a hanging frame 40, which is used to be detachably connected to any load-bearing plate 11. When carrying the load-bearing plate 11, the hanging frame 40 is connected to the load-bearing plate 11, and then the load-bearing plate 11 is lifted by a forklift, an overhead crane or a hoisting machine, and then the support column 12 is threadedly connected and fixed to the load-bearing plate 11 to form a support unit 10, and then the hanging frame 40 is removed, and then the hanging frame 40 is connected and matched with the next load-bearing plate 11.

[0047] By providing the hoisting frame 40 , a single person can operate a forklift, an overhead crane, a hoisting machine or other equipment to perform operations, thereby improving work efficiency and reducing labor costs.

[0048] Furthermore, in this embodiment, the detachable connection between the hanging frame 40 and the load-bearing plate 11 can also be a threaded connection. Specifically, each load-bearing plate 11 is provided with a second threaded hole 112, and the second threaded hole 112 is used to cooperate with the hanging frame 40. Of course, in other embodiments, other detachable connection methods can also be adopted, for example, a card slot is provided on the load-bearing plate 11, and a card protrusion is provided on the hanging frame 40. Through the card engagement between the card protrusion and the card slot, the detachable connection between the load-bearing plate 11 and the hanging frame 40 can also be achieved.

[0049] Please continue to combine Figure 1 Specifically, the windproof baffle 20 includes a first baffle 22, a second baffle 23, a third baffle and a fourth baffle, and the first baffle 22, the second baffle 23, the third baffle and the fourth baffle are respectively detachably connected to two adjacent load-bearing plates 11.

[0050] It can be understood that after the two support units 10 are stacked, that is, after the two ends of the support column 12 are respectively threadedly connected to the two adjacent load-bearing plates 11, the first baffle 22, the second baffle 23, the third baffle and the fourth baffle can be connected to the load-bearing plates 11 in turn, thereby closing the four sides of the two load-bearing plates 11, and then closing the battery pack arranged between the two load-bearing plates 11 to achieve a windproof effect.

[0051] Since the battery pack has other pipes such as liquid cooling pipes and other wiring harnesses such as high and low voltage wires, in order to facilitate the passage of these pipes and wiring harnesses, at least one windproof enclosure 20 is provided with a through hole 21 for the pipes and wiring harnesses of the battery pack to pass through. Figure 1 As shown, in the present embodiment, all the windproof panels 20 are provided with a through hole 21. Specifically, the through hole 21 is provided at the first baffle 22. Of course, in other embodiments, one or more of the second baffle 23, the third baffle or the fourth baffle may be provided with a through hole 21. The specific position and number of the through holes need to be determined according to the actual design requirements of the battery pack.

[0052] It is easy to understand that since the windproof enclosure 20 is provided with a through hole 21, in order to further improve the windproof effect of the windproof enclosure 20, in some embodiments, the windproof test device 100 may also include a blocking piece. When the pipes and wiring harnesses of the battery pack pass through the through hole 21, they can be further blocked by the blocking piece.

[0053] Please continue to combine Figure 1 and Figure 2 In order to improve the overall insulation effect of the windproof test device 100, an insulating layer is provided on the surface of at least one load-bearing plate 11, and an insulating layer is provided on the surface of at least one support column 12. By providing the insulating layer, the occurrence of accidents during the battery test can be reduced, thereby reducing economic losses. Specifically, in this embodiment, the surfaces of all the load-bearing plates 11 and support columns 12 are provided with an insulating layer, and the insulating layer can be achieved by spraying insulating paint. Of course, in some embodiments, other insulating materials can also be bonded or wrapped on the surfaces of the load-bearing plates 11 and support columns 12.

[0054] In addition, the windproof panels 20 can be made of plastic with good insulation performance. Specifically, in this embodiment, at least one windproof panel 20 is made of polycarbonate (PC plastic), which has good insulation and flame retardancy. Of course, in other embodiments, the windproof panels 20 can also be made of other plastic materials such as ABS plastic (Acrylonitrile Butadiene Styrene plastic). In other words, the windproof panels 20 can also be metal sheets sprayed with insulating paint.

[0055] Further, to check the wind force during the test, please refer to Figure 3 , Figure 3 The structural diagram of the support unit 10 provided in this embodiment is combined with Figure 3 The windproof testing device 100 further includes a wind speed sensor 50 , which is disposed on the supporting unit 10 .

[0056] In addition, in order to detect the temperature during the test, in the present embodiment, the windproof test device 100 further includes a temperature sensor 60 , and the temperature sensor 60 is disposed on the support unit 10 .

[0057] It is easy to understand that the wind speed sensor 50 is used to detect the wind force during the test, and the temperature sensor 60 is used to detect and record the temperature during the test; in addition, the data recorded by the wind speed sensor 50 and the temperature sensor 60 can also be used as a control test, and can provide corresponding data support when the windproof enclosure 20 is not installed.

[0058] Through the above instructions, please combine Figure 1-Figure 3 Taking the hanging frame 40, three supporting units 10, and two windproof panels 20 provided in this embodiment as an example, an installation process of the windproof test device 100 is described in detail below:

[0059] Step S10: placing four support columns 12 into an environmental chamber for testing, which may be placed on a test platform or on the ground;

[0060] Step S20: After the hanging frame 40 and the bearing plate 11 are screwed together, they are hung into the environmental chamber using a forklift or an overhead crane.

[0061] Step S30: After the four support columns 12 are screwed and fixed to the bottom of the load-bearing plate 11 , the hanging frame 40 is removed, and then the battery pack is placed on the load-bearing plate 11 ;

[0062] Step S40: Install the other four support columns 12 on the load-bearing plate 11 and tighten them;

[0063] Step S50: Fix the first baffle plate 22 of the windproof enclosure 20 to the load-bearing plate 11 by means of bolts, and then lead the wiring harness and pipeline of the battery pack out from the through hole 21 of the first baffle plate 22 to facilitate connection with the test equipment;

[0064] Step S60: After the hanging frame 40 and the other bearing plate 11 are screwed together, the hanging frame 40 and the other bearing plate 11 are hoisted into the environmental chamber by a forklift or an overhead crane; the bearing plate 11 is screwed together and fixed to the four support columns 12, and the first baffle plate 22 is also bolted to the bearing plate 11, and then the hanging frame 40 is removed;

[0065] Step S70: sequentially bolting and fixing the second baffle 23, the third baffle and the fourth baffle to the upper and lower load-bearing plates 11, respectively, so as to close the battery pack;

[0066] Step S80: Place another battery pack on the upper load-bearing plate 11, and then repeat the above steps S40, S50, S60 and S70; thereby placing the two battery packs in the windproof test device 100, and being able to perform relevant detection tests on the two battery packs at the same time.

[0067] It is easy to understand that if the number of battery pack tests needs to be increased, the support units 10 can be stacked and arranged according to the above steps S40, S50, S60 and S70, and the corresponding windproof panels 20 can be arranged.

[0068] In addition, it should be noted that the above is only one installation process of the windproof test device 100. In some other embodiments, other operating steps can also be performed; for example, multiple support units 10 are assembled in advance and then stacked; the installation order of the first baffle 22, the second baffle 23, the third baffle and the fourth baffle of the windproof enclosure 20 can also be changed, etc.

[0069] In summary, an embodiment of the utility model provides a windproof test device 100, which includes at least three stacked support units 10 and at least two windproof panels 20. The space between two adjacent support units 10 is used to accommodate battery packs. Windproof panels 20 are arranged around the circumference of any two adjacent support units 10. The windproof panels 20 and the two adjacent support units 10 together form a closed space 30 to enclose the battery packs accommodated therein. In other words, multiple battery packs can be placed at the same time by stacking the support units 10, and each battery pack is in the closed space 30 by enclosing the windproof panels 20, thereby protecting the battery packs from wind. Therefore, the windproof test device 100 can test multiple battery packs at the same time, thereby improving the test efficiency.
