Technical Field

[0001] This utility model relates to the field of sealing component technology, and in particular to a lifting door sealing component for a battery test box. Background Technology

[0002] A battery test chamber is a precision testing device specifically designed to evaluate battery performance, safety, and environmental adaptability. It is widely used in battery research and development, production, quality inspection, and fault analysis. By simulating different environmental conditions (such as temperature, humidity, and pressure), the battery test chamber quantitatively tests key indicators of the battery, such as capacity, internal resistance, charge and discharge efficiency, cycle life, and safety performance, to ensure the reliability and safety of the battery under complex operating conditions.

[0003] In existing technologies, traditional testing chamber doors are typically sealed with rubber sealing strips. However, during long-term and frequent opening and closing, the sealing strips are prone to plastic deformation or fatigue aging, leading to a decline in sealing performance and consequently affecting the accuracy of the testing results.

[0009] Preferably, the sealing element has a first inner arc portion and a second inner arc portion on one side. When the door panel is reset, the first inner arc portion and the second inner arc portion respectively squeeze the first guide block and the second guide block into the groove to increase the sealing effect.

[0010] Preferably, a gap is provided between the bottom of the first inner arc portion and the seal.

Detailed Implementation

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figures 1 to 7 A lifting door sealing assembly for a battery testing box includes a box body 1, an opening 2 on one side of the box body 1, the opening 2 communicating with the inner cavity of the box body 1, a sliding groove 3 on both sides of the opening 2, a lifting drive device in each of the two sliding grooves 3, a door panel 4 in the opening 2, and the drive end of the lifting drive device connected to the door panel 4 for driving the lifting of the door panel 4.

[0029] A sealing element 5 is installed on the rear inner wall of the inner cavity of the slide groove 3. A groove 6 is provided on one side of the sealing element 5. Insertion parts are provided on both sides of the door panel 4. The two insertion parts are slidably disposed in the corresponding grooves 6.

[0030] The sealing element 5 is made of fluororubber, which can withstand 250℃ for a long time (up to 300℃ for a short time) and can withstand as low as -20℃ (some modified models can reach -40℃) to increase the sealing effect and service life of the sealing element 5.

[0031] When in use, this device can move the door panel 4 up or down through the lifting drive. During the upward and downward movement of the door panel 4, the connector moves within the groove 6 of the seal 5. When the door panel 4 returns to its original position, the connector abuts against the inner cavity of the groove 6, supporting the seal 5. Supporting the seal 5 by the connector reduces the deformation caused by direct compression of the seal 5, preventing the seal 5 from undergoing plastic deformation or fatigue aging due to long-term compression by the door panel 4, which would lead to a decrease in sealing performance.

[0032] Furthermore, the connector includes a first mounting block 7 and a second mounting block 8, which are located above and below one side of the door panel 4, respectively. A first guide block 9 and a second guide block 10 are respectively mounted on one side of the first mounting block 7 and the second mounting block 8, and the first guide block 9 and the second guide block 10 are adapted to the groove 6 on one side of the sealing member 5. A first inner arc portion 11 and a second inner arc portion 12 are provided on one side of the sealing member 5. When the door panel 4 is reset, the first guide block 9 and the second guide block 10 are pressed into the groove 6 by the first inner arc portion 11 and the second inner arc portion 12, respectively, to increase the sealing effect. When the door panel 4 is moved, the first guide block 9 and the second guide block 10 can be moved along the groove 6 of the sealing member 5 by the first mounting block 7 and the second mounting block 8. At the same time as the door panel 4 is reset, the first guide block 9 and the second guide block 10 are pressed by the first inner arc portion 11 and the second inner arc portion 12 on the sealing member 5, respectively, so that the door panel 4 and the sealing member 5 fit together, thereby increasing the sealing effect.

[0033] Furthermore, a gap 13 is provided between the bottom of the first inner arc portion 11 and the sealing member 5. The lifting drive device includes a cylinder 14 disposed in the slide groove 3 and a slider 15 slidably disposed in the gap 13. The slider 15 is connected to the side of the door panel 4. The drive end of the cylinder 14 is connected to the door panel 4 through a connecting assembly, and the slider 15 is in contact with the first inner arc portion 11 on one side of the sealing member 5. When the slider 15 moves down, it squeezes the first inner arc portion 11. The connecting assembly is a connecting plate 16, which is installed on the top of the door panel 4. The cylinder 14... The drive end is connected to the connecting plate 16, which is longer than the door panel 4. The connecting plate 16 can be pushed by the cylinder 14, which in turn moves the door panel 4. The door panel 4 then moves the slider 15 along the slide groove 3. When the slider 15 moves and resets, one side of the slider 15 will press against the first inner arc part 11, and the bottom end of the first inner arc part 11 will press against the first guide block 9 and the second guide block 10 that are slidably set in the groove 6. This makes the door panel 4 fit more closely with the sealing element 5, increases the sealing effect, and prevents air from entering the inner cavity of the box 1 and affecting the detection effect.

[0034] Furthermore, a sensor detection component 17 is provided on one side of the housing 1 to control the lifting drive device to open the door panel 4 when material is detected. The sensor detection component 17 is an infrared sensor. The infrared sensor does not need to directly contact the battery. It detects parameters such as the position of the battery by emitting infrared rays of a specific wavelength (active) or receiving spontaneous infrared radiation from the environment (passive). The infrared sensor is existing technology and will not be described in detail here.

[0035] Furthermore, a partition 18 is provided inside the housing 1, and a test component 19 is provided inside the partition 18.

[0036] The test component 19 includes devices for regulating test parameters inside the chamber 1, such as heating or cooling. For example, a liquid cooling system uses a liquid medium (such as deionized water, fluorinated liquid, mineral oil, etc.) to dissipate heat instead of air, uses a metal cold plate (copper / aluminum material) to bond the partition, absorbs heat through internal microchannels, and then uses a pump group to deliver the coolant to an external heat dissipation unit (such as a cooling tower) to transfer the temperature to the outside of the chamber 1, thereby cooling the interior of the chamber 1.

[0037] Furthermore, the housing 1 is provided with a placement rack 20 for placing materials. The battery can be placed on the placement rack 20 and the test parameters inside the housing 1 can be adjusted by the test component 19 to test the battery performance inside the housing 1.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
