By adjusting the angle of the L-shaped support splint 6 through the flipping assembly 7, the test product clamped between the two L-shaped support splints 6 can be automatically released without the need for real-time close human participation, thereby improving the safety of the test.

[0033] In this embodiment, the width of the support plate at the bottom of the L-shaped support splint 6 is selected according to actual needs. In this embodiment, the preferred support plate width is 2-4 cm. In other embodiments of the present application, when feasible and necessary, the L-shaped support splint 6 may also be a plate-like structure with an I-shaped longitudinal section, and the test product is supported by the clamping force between the two relative L-shaped support splints 6.

[0034] It should be noted that, in addition to the energy storage power supply described in this application, other products with similar structures can also be tested using the test device of this embodiment.

[0035] The first guide rail includes a first linear guide rail 2, a screw rod 3 and a gear set 4. The layout direction of the first linear guide rail 2 is the same as the axial direction of the screw rod 3, and the axis of the first linear guide rail 2 and the axis of the screw rod 3 are located in the same plane. In this embodiment, the first linear guide rail 2 and the screw rod 3 are preferably located on the rear side of the frame 1. In order to improve the stability of the fixation, the first linear guide rail 2 preferably includes two, which are respectively arranged on both sides of the screw rod 3. The first linear guide rail 2 is an existing conventional linear guide rail, which has a HG25 square slider with a locking function (the square slider is not shown in the figure); the gear set 4 is arranged at one end of the screw rod 3 to drive the screw rod 3 to rotate, such as Figure 4 As shown, the gear set 4 is preferably an umbrella gear set, and the central axis 72 of the gear set 4 is connected to a driving handle 13 or a driving motor. Since the adjustment displacement is small during each test, the present embodiment is preferably connected to a driving handle 13, that is, the height of the test platform is adjusted manually, which saves costs; the first guide rail of the structure drives the test platform to move in the vertical direction through the screw rod 3 as a driving member to achieve height adjustment, and the test platform is fixed and supported by the first linear guide rail 2 to ensure that the test platform moves stably in the vertical direction to avoid displacement or shaking affecting the test effect.

[0036] The second guide slide includes a second linear guide rail 5 and an intermediate connecting plate 8. The intermediate connecting plate 8 is arranged between the second linear guide rail 5 and the first linear guide rail 2 to fix the second linear guide rail 5 on the square slider of the first linear guide rail 2 by bolts or the like. At the same time, a screw nut 9 is provided on the intermediate connecting plate 8. The screw nut 9 is threaded with the screw rod 3 on the first guide slide. With the cooperation of the screw nut 9 and the screw rod 3, when the screw rod 3 rotates, the screw nut 9 will move on the screw rod 3 and thereby drive the second linear guide rail 5 and the test platform located thereon to move synchronously in the vertical direction under the limitation and guidance of the first linear guide rail 2; in this embodiment, the second linear guide rail 5 is also an existing conventional linear guide, which is provided with a plurality of sliders 10 corresponding to the number of the L-shaped support splints 6. It can be understood that for the sake of stability in use, the slider 10 is preferably an existing slider 10 with a locking function.

[0037] It can be understood that in this embodiment, the strokes of the first linear guide rail 2 and the second linear guide rail 5 should be selected according to actual needs, and this embodiment will not be described in detail here.

[0038] The second linear guide rail 5 is provided with a plurality of sliders 10 corresponding to the number of L-shaped support splints 6, and two L-shaped support splints 6 are fixed on the corresponding sliders 10. It can be understood that when the slider 10 is a plate-like slider 10 with a larger area, the two L-shaped support splints 6 can be directly fixed on the slider 10. When the area of ​​the slider 10 is smaller, a connecting plate can be added between the slider 10 and the L-shaped support splint 6 to indirectly fix the L-shaped support splint 6 to the slider 10. In this embodiment, the slider 10 located on the second linear guide rail 5 is preferably a plate-like slider with a larger area.

[0039] In this embodiment, the two L-shaped support splints 6 can be driven manually or by a telescopic drive member 11, which can be selected according to actual needs. In order to achieve automatic and precise adjustment, the second guide slide can include two groups of telescopic drive members 11 extending in the horizontal direction. The two groups of telescopic drive members 11 are respectively located on one side of the two L-shaped support splints 6 to drive the corresponding L-shaped support splints 6 to move relative to the second guide slide. The telescopic drive member 11 is preferably an electric, pneumatic or hydraulic telescopic cylinder that meets the required stroke. One end of the telescopic cylinder is fixed on the slider 10 of the second linear guide rail 5, and the other end is fixed on the side edge of the frame 1; in order to save costs, the L-shaped support splint 6 can also be adjusted by manual pushing. Since the adjustment distance is small each time, in order to save costs, it is preferred to manually adjust the distance between the two L-shaped support splints 6.

[0040] The flip assembly 7 includes a linkage frame 71, a central axis 72 and a telescopic connecting rod 73. The linkage frame 71 is fixed to the outer side of the L-shaped support clamping plate 6, which is the opposite side of the clamping surface and is pivotally connected to the central axis 72; the central axis 72 is fixed to the second guide slide and extends along the width direction of the L-shaped support clamping plate 6. It can be understood that the central axis 72 should be in a fixed state, and its fixed position should not affect the normal movement of the L-shaped support clamping plate 6. In this embodiment, the central axis 72 is preferably fixed to the slider 10 of the second linear guide rail 5 in the second guide slide. Of course, when the area of ​​the slider 10 is small, an indirect connection can be made with the help of a connecting plate; one end of the telescopic link 73 is connected to the central axis 72, and the other end is connected to the linkage frame 71. The telescopic action of the telescopic link 73 can drive the linkage frame 71 to rotate relative to the central axis 72, and then drive the L-shaped support splint 6 to flip relative to the central axis 72, and then release the test product. It can be understood that an eight-shaped structure should be formed between the two L-shaped support splints 6 after flipping, that is, the bottom openings of the two L-shaped support splints 6 become larger after flipping, and the test product falls at this time.

[0041] In this embodiment, the central axis 72 on the flip assembly 7 includes two groups arranged in parallel in the horizontal direction, such as Figure 2 As shown, one group close to the L-shaped supporting clamp plate 6 is pivotally connected to the linkage frame 71 , and the other group is pivotally connected to one end of the telescopic connecting rod 73 .

[0042] In this embodiment, the telescopic connecting rod 73 is an existing conventional electric cylinder, pneumatic cylinder or hydraulic cylinder. In this embodiment, a pneumatic cylinder is preferably used. The telescopic stroke of the telescopic connecting rod 73 is selected according to actual needs so as to be able to drive the L-shaped supporting splint 6 to flip and release the test product.

[0043] The use principle of this embodiment includes: determining the product to be tested, rotating the screw 3 by driving the handle 13 according to the model of the product to be tested and the test requirements to adjust the height of the test platform, and manually adjusting the distance between the two L-shaped support clamps 6. After the adjustment is completed, the test product is placed on the L-shaped support clamp 6 to support and fix it, and finally the telescopic connecting rod 73 is started to drive the L-shaped support clamp 6 to flip to release the test product to complete the test.

[0044] In summary, when the drop test device of the present embodiment is used, the two L-shaped support clamps 6 and the flip assembly 7 on the test platform can be used to fix and release test products of different sizes or models, thereby simplifying the fixing procedure and structure of the test products. The release process does not require close human participation, thereby improving the safety of the test. In addition, the cooperation of the first guide slide and the second guide slide can also control the adjustment of the test platform height and the clamping width to meet various test requirements, thereby improving the flexibility of use. Therefore, the test device of the present embodiment has a simple structure, is easy and quick to use, and solves the existing problems.

[0045] As a preferred embodiment of the present application, in order to further improve the safety performance of the test and avoid or reduce the loss caused by the explosion of the energy storage power supply during the test, a protective plate 12 is preferably provided on the outer periphery of the rack 1 near the bottom, and a test product drop zone is formed between the protective plate 12 and the drop platform at the bottom of the rack 1. The test product is enclosed by the test product drop zone to prevent the explosion from splashing out. It can be understood that the protective plate 12 can be a stainless steel plate that is resistant to high temperature and corrosion and is economical.

[0046] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several improvements can be made without departing from the premise of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
