[0032] This application provides a residential energy storage casing sealing test device. Please refer to [link / reference]. Figure 1 It includes: a test stand 100, a fixing frame 400, a clamping device, a test device 300, and a sealing device 200.

[0033] Please refer to Figures 2-5 The test bench 100 is trough-shaped, including a tabletop and side walls 101 on both sides of the tabletop. The test bench 100 has two pre-set test stations for simultaneously performing sealing tests on two residential energy storage housings. A feeding plate 114 is provided on the tabletop. Adjusting bolts 113 are provided between the tabletop and the feeding plate 114 to adjust the height of the feeding plate 114 to accommodate residential energy storage housings of different sizes. Ball bearings 108 are provided on the surface of the feeding plate 114 to facilitate the transport of the energy storage housing to be tested. Support legs 102 are provided at the bottom of the test bench 100 for support. Two through holes 110 are provided on the tabletop of the test bench 100, and through holes 109 are provided on the feeding plate 114 to facilitate the lifting of the testing device 300 during testing and its contact with the residential energy storage housing.

[0034] A pressure plate 104 is provided above the side wall 101 to press the residential energy storage housing under test during testing. The pressure plate 104 is connected via a telescopic assembly 103. The pressure plate 104 is raised and lowered by controlling the telescopic assembly 103 to accommodate sealing housings of different heights and to press the energy storage housing under test firmly, preventing the housing from being pushed up during testing. Clamping plates are provided at the front and middle of the side wall for positioning the energy storage housing under test. The first set of clamping plates 105 is located at the front of the side wall 101. The second set of clamping plates 112 is located at the middle of the side wall of the test bench 100. The clamping plates 105 are connected to the side wall 101 via connecting blocks 106. The connecting blocks 106, clamping plates 105, and clamping plates 105 are fixed together by pins 107.

[0035] A mounting bracket 400 is externally mounted on the test bench 100 for securing the test bench 100. The mounting bracket 400 adopts a gantry structure, including two top crossbeams and four trapezoidal support legs installed at the bottom of the two crossbeams. The two crossbeams are fixed by several fixing strips. The gantry 401 is located on the outer side of the side wall 101, and a fixing plate 402 is respectively provided in the middle of the support leg of the gantry 401 on each side of the outer side of the side wall 101. The fixing plate 402 is used to install the sealing device 200.

[0036] A sealing device 200 is provided on the outer side of each of the two sidewalls 101 for sealing the openings of the energy storage housing under test during airtightness testing. The energy storage housing typically has multiple openings for installing electrical interfaces. During airtightness testing, these openings must be sealed to test the airtightness of the remaining parts of the housing. The sealing device 200 comprises at least two sets, mounted on a mounting bracket 400. Its number is determined by the number of openings in the housing under test. The sealing device 200 includes a sealing cylinder 203 and a plug 205 located at the front end of the sealing cylinder. A horizontal groove 111 is formed in the body of the sidewall 101, through which the plug of the sealing device 200 extends into the inner side of each of the two sidewalls 101. The sealing device 200 is mounted on a mounting plate 402 via a guide rail. The horizontally positioned groove 111 allows for horizontal adjustment of the sealing device's position to accommodate openings at different locations on the energy storage housing. Optionally, the plug size of the sealing device 200 can be different, such as... Figure 4 As shown, one set of sealing devices uses plug 205, and the other set of sealing devices uses sealing block 204.

[0037] At least two sets of clamping devices are provided on the outer sides of the two sidewalls 101 for clamping and fixing the two residential energy storage shells to be tested. The figure shows the case where four sets of clamping devices are used. Four sets of clamping devices 201 are installed on the body of the sidewall 101 and above the slide groove 111 for clamping and fixing the energy storage shells to be tested. The four sets of clamping devices are spaced apart along the length of the test bench 100. Each set of clamping devices 201 includes two fixing components arranged opposite each other, respectively disposed on the two sidewalls 101. Each fixing component includes a clamping cylinder and a locking block 202 installed at the front end of the clamping cylinder.

[0038] Please refer to Figure 6-8The testing device 300 is located at the bottom of the testing platform 100 and is used for sealing tests. The testing device 300 includes a protective shell 301 and a protective plate 302, with the protective plate 302 detachably connected to the outside of the protective shell 301. Two sets of airtightness testing components are installed inside the protective shell 301, used for airtightness testing at two different workstations. Each set of airtightness testing components includes a lifting cylinder 304 and a sliding roller 305. The lifting cylinder 304 is located at the clamping end of the fixing block 303. The output end of the lifting cylinder 304 is fixedly connected to the sliding roller 305. An air outlet pipe 307 is provided at the top of the sliding roller 305, and an air supply pipe 309 is provided at the bottom of the sliding roller 305. An air cover 308 is provided outside the air outlet pipe 307 to prevent air leakage between the air outlet pipe 307 and the shell during air supply. The air supply pipe 309 is connected to the air inlet pipe. The airtightness testing components also include a pressure sensor 306 and an air valve 310. A pressure sensor 306 is arranged around the sliding roller 305 to sense whether the sliding roller 305 is in contact with the energy storage housing under test. An air valve 310 is located on the air supply pipe 309 to control the airflow. The testing device 300 also includes a controller (not shown), electrically connected to the pressure sensor 306 and the air valve 310. When good contact between the sliding roller 305 and the housing under test is detected, the controller opens the air valve 310 to inflate the housing and perform a sealing test. The air supply pipe 309 is connected to an airtightness tester via an air inlet pipe, and the airtightness tester determines the sealing performance of the housing.

[0039] The working process of the household energy storage casing sealing test equipment in this embodiment is as follows:

[0040] First, the residential energy storage housing to be tested is conveyed into the test bench 100. The test bench 100 includes two stations, which can be used to perform airtightness tests on two housings simultaneously. After being conveyed into place, the pressure plates 104 at the middle and front end of the side wall 101 of the test bench 100 are positioned at the front end of the residential energy storage housing to be tested. The test holes of the energy storage housing are aligned downwards, corresponding to the air hood 308. The lifting cylinder 304 is activated, driving the sliding roller 305 to move upwards, simultaneously driving the air outlet pipe 307, the air hood 308, and the pressure sensor 306 to move upwards synchronously. The pressure sensor 306 detects whether the rise has reached the correct position.

[0041] Once the residential energy storage housing to be tested is delivered to the designated location, the cylinder of the sealing device 200 is activated, sealing the openings in the housing via the plug and sealing block. Simultaneously, the clamping cylinder of the clamping device is activated, driving the clamping block to clamp and fix the residential energy storage housing to be tested.

[0042] Once the sliding roller 305 has risen to its designated position, it indicates that the vent pipe 307 and the air hood 308 have aligned with the test hole of the energy storage housing. The controller then opens the air valve 310, allowing the airtightness tester to inflate the housing under test for a sealing test. After the test is completed, the lifting cylinder 304 is activated, causing the sliding roller 305 and the vent pipe 307 to move downwards. The clamping cylinder and the sealing cylinder retract, simultaneously lifting the clamping plate at the front end of the residential energy storage housing under test. After the vent pipe 307, the sealing block, and the plug have exited the housing under test, and the clamping device has been released, the residential energy storage housing under test is sent out of the test bench 100.

[0043] The residential energy storage housing sealing test equipment of this application expands its applicability by creating sliding grooves on both side walls of the test bench and installing the sealing device via guide rails. This allows for horizontal adjustment of the sealing device to accommodate openings at different locations on various residential energy storage housings. Liftable pressure plates are installed above the side walls, and clamping devices are installed on the side walls to clamp and fix the housing in both height and horizontal directions during testing, preventing movement and improving the housing's stability. By installing the test device at the bottom of the test bench and creating perforations on the test bench surface and discharge plate, the test device can be easily lifted from the bottom of the test bench for testing. The clamping device and sealing device are located on the side walls, resulting in a simpler and more rational layout, improving the automation and efficiency of the sealing test.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
