[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0034] To address the technical problem in existing technologies where the diameter of the annular hole in the iron chain is typically larger than the diameter of the buckle, resulting in a certain gap in the chamber door after it is secured by the iron chain, thus causing inadequate sealing of the sample chamber and hindering the formation of simulated climate within the test chamber, this invention provides a battery climate simulation device. This device avoids the problem of a certain gap remaining in the chamber door due to iron chain fixation, improves the sealing performance of the simulation chamber, facilitates the formation of climate within the simulation chamber, and features a simple structure and relatively convenient operation.

[0035] Please see Figures 1 to 3 , Figures 1 to 3 This is a schematic diagram of the structure of a battery climate simulation device according to an embodiment of the present invention. The battery climate simulation device includes a climate chamber 1, a door 2, and a locking part 3. The climate chamber 1 has a simulation cavity 1a with an opening on one side. The door 2 is movable relative to the climate chamber 1 and can open and close the opening of the simulation cavity 1a when it is movable. The locking part 3 is slidably connected to the climate chamber 1, and its sliding direction is parallel to the plane where the opening of the simulation cavity 1a is located. The locking part 3 has a first position state that presses against the door 2 and keeps the door 2 in a closed opening position, and a second position state that disengages from the door 2 and allows the door 2 to open the opening. Specifically, when the locking part 3 slides, it can press the door 2 against the closed opening of the simulation cavity 1a, which is the first position state, and it can slide away from the door 2 to switch to the second position state.

[0036] In the battery climate simulation device provided by this utility model, when the locking part 3 slides to the position where it presses the door 2 against the opening of the closed simulation cavity 1a, and when combustion or explosion occurs in the simulation cavity 1a and impacts the door 2, since the sliding direction of the locking part 3 is parallel to the plane where the opening of the simulation cavity 1a is located, that is, the direction of the impact force intersects with the sliding direction of the locking part 3, the locking part 3 will not move away from the door 2, so that the door 2 can stably close the opening of the simulation cavity 1a, and can avoid the problem that the door 2 still has a certain amount of movement gap due to the iron chain fixing, improve the sealing performance of the simulation cavity 1a, facilitate the formation of climate in the simulation cavity 1a, and has a simple structure and relatively convenient operation.

[0037] It should be noted that the simulation cavity 1a is equipped with a climate simulation device to generate various climates. Its specific structure and working principle are existing technologies and will not be described in detail here.

[0038] In one embodiment, the climate chamber 1 has a guide channel 13a located on the opening side of the simulation cavity 1a, with its axis parallel to the plane containing the opening of the simulation cavity 1a and intersecting the opening direction of the simulation cavity 1a; the locking part 3 is slidably inserted into the guide channel 13a. Specifically, in this solution, the opening side of the simulation cavity 1a is a blocking side 11, and the chamber door 2 is blocked by the blocking side 11 when closing the opening of the simulation cavity 1a.

[0039] In this embodiment, the blocking side 11 and the locking part 3 are clamped on both sides of the box door 2 to achieve stable positioning of the box door 2. At the same time, the guide channel 13a guides the locking part 3, ensuring that the locking part 3 can be stably pressed against the outside of the box door 2, further preventing the box door 2 from having any movement gaps. Specifically, in this solution, the blocking side 11 is provided with a guide protrusion 13, and the guide channel 13a is formed in the guide protrusion 13.

[0040] Furthermore, it should be noted that in this design, there is no rotating connection between the door 2 and the climate chamber 1. Instead, the door 2 and the climate chamber 1 are separate units. When the locking part 3 disengages from the door 2, the door 2 can automatically fall to open the simulation chamber 1a, improving convenience. At the same time, the absence of a hinge connection effectively avoids the problem of the door 2 failing to close properly due to heat deformation of the hinge.

[0041] In one embodiment, there are multiple guide channels 13a, which are parallel to each other and spaced apart; there are multiple locking parts 3, which are slidably disposed in the multiple guide channels 13a.

[0042] In this embodiment, multiple guide channels 13a are provided and arranged circumferentially along the opening of the simulation cavity 1a to further improve the stability of the locking part 3 pressing and limiting the door 2, thereby improving the sealing performance of the simulation cavity 1a. It should be noted that in this solution, there are two sets of guide channels 13a, which are located on opposite sides of the opening of the simulation cavity 1a. Correspondingly, there are two sets of locking parts 3.

[0043] Furthermore, it should be noted that the locking part 3 is not limited in its configuration; it can be a locking plate, a telescopic rod, or other forms. The door 2 is also equipped with a handle 22.

[0044] In one embodiment, the locking part 3 includes a pull plate 31 and a plurality of locking arms 32. The plurality of locking arms 32 are all connected to the pull plate 31, and at least one locking arm 32 is movably inserted in the guide channel 13a. When moving along the axial direction of the guide channel 13a, it can restrict the movement of the box door 2 in a direction away from the simulation cavity 1a and can disengage from the box door 2. The battery climate simulation device also includes a stop block 21, which is installed on the box door 2 and located between two adjacent locking arms 32.

[0045] In this embodiment, pulling the pull plate 31 simultaneously drives multiple locking parts 3 to move synchronously, meaning that multiple locking arms 32 can simultaneously press against the cabinet door 2. Meanwhile, since the cabinet door 2 is provided with a stop block 21 located between two locking arms 32, it can... Figure 3 For example, the stop block 21 is limited by two adjacent locking arms 32, which can limit the accidental vertical displacement of the door 2 and further improve the stability of the door 2 when it is closed.

[0046] In one embodiment, multiple guide channels 13a are provided, the multiple guide channels 13a are axially parallel, and multiple locking arms 32 are respectively movably inserted through the multiple guide channels 13a.

[0047] In this embodiment, multiple locking arms 32 are respectively inserted into multiple guide channels 13a, thereby providing stable guidance for each locking arm 32. Specifically, in this solution, each group has two guide channels 13a, and correspondingly, each group has two locking arms 32.

[0048] In one embodiment, the battery climate simulation device further includes an elastic element 4, which connects the pull plate 31 and the climate chamber 1, and is used to drive the locking arm 32 from the position of disengaging from the chamber door 2 to the position of blocking the chamber door 2.

[0049] In this embodiment, an elastic element 4 is designed between the pull plate 31 and the climate chamber 1 to ensure that the locking arm 32 can be stably positioned to block the chamber door 2, further improving the stability of the chamber door 2 when closing the simulated cavity 1a. It should be noted that the elastic element 4 can be one of a leaf spring, a coil spring, a torsion bar spring, and a gas spring. Specifically, in this solution, the elastic element 4 is a coil spring.

[0050] In one embodiment, please refer to Figure 1 The climate chamber 1 has multiple control buttons 12 on its outer side; the battery climate simulation device also includes a rotating shaft 5, a flexible protective curtain 51 and a retraction drive unit 52. The rotating shaft 5 is rotatably mounted on the climate chamber 1 and is located above the control buttons 12. The flexible protective curtain 51 is rolled up around the rotating shaft 5 and is retracted when the rotating shaft 5 rotates, and blocks the control buttons 12 when it is lowered. The retraction drive unit 52 is connected to the rotating shaft 5 and is used to drive the rotating shaft 5 to rotate.

[0051] In this embodiment, when the equipment is not in use, the retraction drive unit 52 can drive the rotating shaft 5 to rotate, thereby lowering the flexible protective curtain 51. This allows the flexible protective curtain 51 to protect external components such as the control buttons 12 and the display panel, extending the equipment's lifespan. It should be noted that the retraction drive unit 52 can be one of a high-speed motor, a low-speed motor, a constant-speed motor, or a variable-speed motor. Specifically, in this solution, the retraction drive unit 52 is a variable-speed motor. The flexible protective curtain 51 can be a transparent curtain.

[0052] In one embodiment, please refer to Figure 4 The climate chamber 1 is also provided with a card slot 1c, which is located on the same side of the climate chamber 1 as the control button 12 and below the control button 12; the battery climate simulation device also includes a card block 53, which is connected to the flexible protective curtain 51 and can be locked in the card slot 1c.

[0053] In this embodiment, after the flexible protective curtain 51 is lowered into place, the locking block 53 on it is locked in the locking groove 1c to position the lower end of the flexible protective curtain 51 and prevent it from swinging randomly. The structure is simple and the operation is convenient.

[0054] In one embodiment, the battery climate simulation device also includes a plurality of rollers 6 mounted on the bottom of the climate chamber 1.

[0055] In this embodiment, multiple rollers 6 are provided at the bottom of the climate chamber 1 to facilitate flexible movement and improve convenience. Specifically, in this solution, the rollers 6 are provided in two sets at intervals, and each set has two rollers 6 spaced apart.

[0056] In one embodiment, please refer to Figure 3 and Figure 5 The battery climate simulation device also includes a lifting plate 7 and a lifting drive unit 71. The lifting drive unit 71 is installed in the climate chamber 1 and has a telescopic rod that points to the ground and is connected to the lifting plate 7.

[0057] In this embodiment, after the device moves to a preset position, the lifting drive unit 71 drives the lifting plate 7 to descend until the lifting plate 7 presses against the ground, preventing the roller 6 from accidentally moving the device and improving testing safety. When it is necessary to move the device, the lifting plate 7 is then driven off the ground. It should be noted that the lifting drive unit 71 can be a pneumatic cylinder, a hydraulic cylinder, or an electric actuator. Specifically, in this solution, the lifting drive unit 71 is a hydraulic cylinder.

[0058] In addition, to ensure the stability of the lifting plate 7, the climate box 1 is also provided with an extension channel in the vertical direction. The lifting plate 7 is provided with a guide rod 72 corresponding to the extension channel, and the guide rod 72 passes through the extension channel.

[0059] To better understand this utility model, the following is combined with... Figures 1 to 5 The technical solution of this utility model is described in detail below:

[0060] When in use, the device is pushed, and the roller 6 moves the device. After the device moves to a suitable position, the lifting drive unit 71 is activated. The lifting drive unit 71 drives the lifting plate 7 to descend, so that the lifting plate 7 is tightly attached to the ground, preventing the roller 6 from accidentally moving the device. When the lifting plate 7 rises and falls, the guide rod 72 will slide up and down inside the extension channel, thereby guiding the lifting plate 7 and improving the stability of the lifting plate 7.

[0061] When batteries need to be installed, pull the pull plates 31 on both sides. The pull plates 31 move the locking arms 32 outward, thereby disengaging the door 2. After the door 2 is disengaged, it falls from the front of the climate chamber 1, making it easier to place the batteries inside the simulation chamber. After the batteries are placed, place the door 2 back at the opening of the simulation chamber 1a to cover the interior of the simulation chamber 1a. The locking arms 32 and the stop block 21 limit the movement, ensuring the stability of the door 2 when closed.

[0062] Then, the climate inside the simulation chamber 1a is controlled via control button 12 to simulate the climate and test the battery. When the device is not in use, the retraction drive unit 52 is activated, which drives the rotating shaft 5 to rotate and unroll the flexible protective curtain 51 to the front of the device, thereby protecting the display screen and control buttons 12 at the front of the device from damage due to prolonged exposure. When the bottom of the flexible protective curtain 51 descends to the appropriate position, the locking block 53 is embedded inside the fixing block, thereby limiting the bottom of the flexible protective curtain 51.

[0063] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
