Description

Technical Field

[0001] This utility model relates to the field of battery testing equipment technology, and in particular to a windproof device for a battery air-cooled test cabinet. Background Technology

[0002] During application, batteries need to be tested at different temperatures to determine their performance. Battery test cabinets typically maintain a constant temperature within the cabinet using air cooling. Batteries are placed inside this temperature-controlled chamber for testing, and airflow is generally used to maintain this temperature. When building a battery thermal model, the measured temperatures of various points on the battery are input for benchmarking; therefore, the accuracy of the measured battery temperatures affects the accuracy of the thermal model. Furthermore, because the batteries inside the cabinet need to be connected to external devices via cables, and different battery specifications have different cable thicknesses, numbers, and distribution locations, existing cabinets often have a single, large, universal wiring hole for the cables. This hole design cannot completely seal the cable, preventing effective enclosure sealing. Consequently, the temperature inside the cabinet is affected by the airflow from the test cabinet, thus influencing the battery's temperature during testing and causing deviations in the measured battery temperature. Utility Model Content

[0003] The purpose of this utility model is to provide a windproof device for a battery air-cooled test cabinet. It has a simple structure and can effectively wrap and seal cables of different specifications and quantities, improve the sealing of the windproof box, and thus improve the accuracy of battery testing.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A windproof device for a battery air-cooled test cabinet is provided, comprising a windproof box body, a test cavity for placing batteries within the windproof box body, an opening communicating with the test cavity on one side of the windproof box body, and a baffle assembly for closing the opening. The baffle assembly includes a first baffle, a first flexible closure member, a second baffle, and a second flexible closure member. Two first baffles are arranged side by side along a first direction at the opening, and the two first baffles are movably connected to the windproof box body. A first flexible closure member is provided on each of the opposite sides of the two first baffles. The second baffle is located on the side of the first baffles away from the test cavity, and the second baffle covers the area between the two first baffles. A second flexible closure member is provided at one end of the second baffle along a second direction, and the first direction and the second direction are arranged at an angle.

[0006] In one embodiment, the first baffle is provided with a pressing baffle, the pressing baffle including a support portion and a pressing portion arranged at an angle, the end of the second baffle having the second flexible closure member abuts against the support portion, and the pressing portion abuts against the side of the second baffle away from the first baffle and presses the second baffle against the first baffle.

[0007] In one embodiment, the extrusion section is wavy.

[0008] In one embodiment, the battery air-cooling device further includes an elastic element connected to each of the two first baffles, the elastic element always having a tendency to drive the two first baffles closer to each other.

[0009] In one embodiment, the elastic element includes an elastic body and connectors disposed at both ends of the elastic body, wherein the elastic body is detachably connected to the two first baffles respectively through the connectors.

[0010] In one embodiment, the windshield box is provided with a groove near the opening, the length direction of the groove extends along the first direction, and the two first baffles are respectively movably disposed in the groove.

[0011] In one embodiment, an anti-slip layer is provided on the surface of the first baffle that abuts against the chute and / or on the wall of the chute.

[0012] In one embodiment, the windshield housing is provided with a locking component for locking the first baffle and / or the second baffle to the windshield housing.

[0013] In one embodiment, the locking component includes a mounting base, a latch, and a switch. The latch is movably connected to the mounting base. The first baffle and / or the second baffle are provided with a plurality of lock holes corresponding to the shape of the latch. The switch is throttle connected to the latch to drive the latch to insert into or disengage from the lock holes.

[0014] In one embodiment, the first flexible closure and / or the second flexible closure is a silicone soft brush.

[0015] The beneficial effects of this utility model are:

[0016] This utility model discloses a windproof device for a battery air-cooled test cabinet. It includes a test chamber for battery placement within the windproof enclosure, with an opening on one side for the battery to be inserted and for cables connecting the battery to external equipment to pass through. During testing, the battery is placed into the test chamber through the opening, and the corresponding cables are connected. Then, two first baffles are brought closer together in a first direction to seal the test chamber. Simultaneously, the cables are gathered and flexibly compressed and wrapped by first flexible sealing members on opposite sides of the two first baffles, ensuring a close fit between the first flexible sealing members and the cables, thereby improving the sealing of the test chamber.

[0017] However, in some operational situations, when there are many cables, thick diameter cables, or cables with large distances between them along the first direction, simply merging two first baffles along the first direction may not be enough to completely enclose the cables. In such cases, a second baffle is placed on the side of the first baffle away from the opening, positioned at the junction of the two first baffles. This second baffle effectively blocks the gaps or seams between the two first baffles, improving the airtightness of the test chamber. Simultaneously, a second flexible sealing element is placed at one end of the second baffle along the second direction, further enclosing the cables. The combined enclosure of the first and second flexible sealing elements, distributed at an angle, effectively achieves complete cable sealing, enabling effective enclosure of cables of different specifications, quantities, and wiring methods, thus improving the airtightness of the test chamber.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0034] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0035] like Figures 1 to 10 As shown, this embodiment of a windproof device for a battery air-cooled test cabinet includes a windproof box 100, a test cavity 110 for placing batteries inside the windproof box 100, an opening 120 communicating with the test cavity 110 on one side of the windproof box 100, and a baffle assembly for closing the opening 120. The baffle assembly includes a first baffle 200, a first flexible closure member 210, a second baffle 300, and a second flexible closure member 310. Two first baffles 200 are arranged side by side along a first direction at the opening 120, and the two first baffles 200 are movably connected to the windproof box 100. A first flexible closure member 210 is provided on the opposite side of the two first baffles 200. The second baffle 300 is located on the side of the first baffles 200 away from the test cavity 110, and the second baffle 300 covers the area between the two first baffles 200. A second flexible closure member 310 is provided at one end of the second baffle 300 along a second direction. The first direction and the second direction are arranged at an angle.

[0036] In this embodiment, a test chamber 110 for placing the battery is provided inside the windshield housing 100, and an opening 120 is provided on one side of the windshield housing 100 for inserting the battery and for the cable 2 for connecting the battery to an external device to pass through. During the test, the battery is placed into the test chamber 110 through the opening 120, and the corresponding cable 2 is connected. Then, two first baffles 200 are brought closer together along a first direction to close the test chamber 110. At the same time, the cable 2 is gathered and flexibly squeezed and wrapped by a first flexible sealing member 210 on the opposite side of the two first baffles 200, so that the first flexible sealing member 210 fits against the cable 2, thereby improving the sealing of the test chamber 110.

[0037] However, in some operational situations, where there are many cables 2, their diameter is thick, or the distance between cables 2 is far, such as... Figures 2 to 4 As shown, in some tests of square batteries 1, the two cables 2 of the square battery 1 are far apart along the first direction. Even with the two first baffles 200 approaching and merging along the first direction, it is still impossible to completely enclose the cables 2. In this case, a second baffle 300 is set on the side of the first baffle 200 away from the opening 120. The second baffle 300 covers the area between the two first baffles 200, thereby blocking the gap or seam between the two first baffles 200 and improving the sealing performance of the test cavity 110. At the same time, by setting a second flexible sealing member 310 at one end of the second baffle 300 along the second direction, the second flexible sealing member 310 further encloses the cables 2. With the first flexible sealing member 210 and the second flexible sealing member 310 distributed at an angle together to enclose the cables 2, the complete sealing of the cables 2 can be effectively achieved. This can effectively enclose cables 2 of different specifications, quantities, and wiring methods, thereby improving the sealing performance of the test cavity 110.

[0038] Specifically, the first direction is parallel to the horizontal direction, and the second direction is parallel to the vertical direction. When the second baffle 300 is installed, its own weight can drive the second flexible sealing member 310 to squeeze and wrap the cable 2, further improving the sealing effect. At the same time, the second baffle 300 can also reinforce the connection between the first baffles 200, enhancing the structural stability of the entire device.

[0039] Furthermore, the dimension of the second baffle 300 along the first direction is larger than the gap or joint at the connection of the two first baffles 200, to ensure that the second baffle 300 can completely cover the gap or joint between the two first baffles 200. In actual operation, the dimension of the second baffle 300 along the first direction is equal to the dimension of the opening 120 along the first direction, ensuring that when there is a gap between the first baffle 200 and the opening 120, the second baffle 300 can effectively cover the opening 120, preventing gas or heat in the test chamber 110 from leaking out through the gap or joint, thereby further improving the sealing performance of the test chamber 110.

[0040] In one embodiment, the first baffle 200 is provided with a pressing baffle 220, which includes a support portion 221 and a pressing portion 222 arranged at an angle. The second baffle 300 is provided with a second flexible sealing member 310, one end of which abuts against the support portion 221. The support portion 221 supports the second baffle 300. The pressing portion 222 abuts against the side of the second baffle 300 away from the first baffle 200 and presses the second baffle 300 against the first baffle 200 to enhance the connection tightness between the two first baffles 200 and the second baffle 300, thereby further improving the sealing performance of the test chamber 110.

[0041] In one embodiment, the extrusion part 222 is wavy, which effectively improves the overall structural strength of the extrusion part 222. This allows the extrusion part 222 to tightly press and press the second baffle 300 against the first baffle 200, thereby enabling the second baffle 300 to block and seal the gap or seam between the two first baffles 200. Furthermore, the wavy design also provides a certain degree of elastic cushioning, accommodating the insertion of second baffles 300 of different thicknesses to a certain extent, thus improving the applicability and flexibility of the device. Of course, in other embodiments, the extrusion part 222 can also adopt other structures or shapes, such as serrated or spiral structures, as long as the extrusion part 222 can effectively press and press against the second baffle 300. Such designs are all within the protection scope of this utility model.

[0042] In one embodiment, the battery air-cooling device further includes an elastic element 400, which is connected to two first baffles 200 respectively. The elastic element 400 always has the tendency to drive the two first baffles 200 to move closer to each other, so that the two first baffles 200 can effectively compress and wrap the cable 2 through the first flexible sealing member 210, thereby further improving the sealing performance of the test chamber 110.

[0043] In one embodiment, the elastic element 400 includes an elastic body 410 and connectors 420 disposed at both ends of the elastic body 410. The elastic body 410 is detachably connected to the clamping plates 220 of the two first baffles 200 via the connectors 420, facilitating the disassembly and installation of the elastic element 400. This allows for easy opening of the test chamber 110 during testing to allow for battery insertion and removal. In actual operation, the connectors 420 are configured as hooks, which are hung on the two clamping plates 220, making operation simple and convenient. Of course, the connectors 420 can also adopt other structures, such as hanging rings or buckles, as long as the detachable connection between the connectors 420 and the clamping plates 220 can be achieved. Such designs are all within the protection scope of this utility model.

[0044] In one embodiment, a groove 130 is provided near the opening 120 in the windshield housing 100. The length direction of the groove 130 extends along a first direction. Two first baffles 200 are respectively movably disposed within the groove 130. The groove 130 facilitates the movement of the two first baffles 200 along the first direction to realize the opening and closing operation of the test chamber 110. At the same time, the groove 130 also guides the movement of the first baffles 200, making the first baffles 200 more stable during movement and avoiding the problem of reduced sealing caused by the two first baffles 200 not being fully aligned due to unstable movement.

[0045] In one embodiment, an anti-slip layer 500 is provided on the surface of the first baffle 200 that abuts against the slide groove 130 and / or on the groove wall of the slide groove 130 to prevent the first baffle 200 from slipping within the slide groove 130, ensuring that the first baffle 200 can stably seal the test chamber 110. This design not only improves the sealing performance of the windshield box 100 but also ensures the stability of the position of the first baffle 200 during the test, thereby improving the accuracy of the test.

[0046] In one embodiment, the windshield housing 100 is provided with a locking component 600 for locking the first baffle 200 and / or the second baffle 300 to the windshield housing 100. The locking component 600 can further ensure the sealing of the test chamber 110 and prevent the first baffle 200 and / or the second baffle 300 from becoming loose or opening during the test. Specifically, the locking component 600 includes a mounting base 610, a locking tongue 620, and a switch 630. The locking tongue 620 is movably connected to the mounting base 610, and the first baffle 200 and / or the second baffle 300 are provided with lock holes 320 corresponding to the shape of the locking tongue 620. After the first baffle 200 and the second baffle 300 are installed and the opening 120 of the test chamber 110 and the cable 2 are sealed by the first baffle 200 and the second baffle 300, the locking tongue 620 is inserted into the corresponding locking hole 320 and locked by the switch 630, thereby locking the first baffle 200 and / or the second baffle 300. This design is simple and convenient to operate, and has a good locking effect, which can further improve the accuracy of the test. At the same time, the setting of the locking component 600 can also improve the safety of the test device and prevent accidents during the test.

[0047] Furthermore, such as Figure 9 As shown, taking the second baffle 300 as an example, multiple locking holes 320 are provided, arranged side by side. This allows the operating switch 630 to insert the locking tongue 620 into the corresponding locking hole 320 based on the specific position of the second baffle 300 when it presses against and wraps the cable 2, achieving precise locking of the second baffle 300 and improving the applicability and flexibility of the locking component 600. This design can adapt to cables 2 of different specifications, quantities, and wiring methods, ensuring the sealing of the test chamber 110 and the accuracy of the test. In actual operation, the locking hole 320 of the first baffle 200 is set in the same principle as that of the second baffle 300. The number and arrangement of the locking holes 320 can be set according to specific needs to meet the requirements of different first baffles 200, second baffles 300, and test scenarios.

[0048] In one embodiment, the first flexible sealing member 210 and / or the second flexible sealing member 310 are high-temperature resistant silicone soft brushes. These brushes are soft and durable, effectively and flexibly compressing and wrapping the cable 2 without damaging it. The bristles of the silicone soft brush adhere tightly to the surface of the cable 2, thereby improving the sealing effect. Furthermore, the silicone soft brush has a certain degree of elasticity, adapting to different specifications and quantities of cables 2, making the device suitable for various testing scenarios and highly versatile. Of course, in other embodiments, the first flexible sealing member 210 and the second flexible sealing member 310 can also adopt other structures, such as sponge, rubber strips, or other soft and elastic materials, as long as they can achieve flexible wrapping and sealing of the cable 2 under test and improve the sealing performance of the test cavity 110. Such designs are all within the protection scope of this utility model.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
