[0032] like Figure 1 to Figure 2As shown, the battery testing device of this embodiment includes: a box 11, a detection mechanism and a moving mechanism. The detection structure is arranged inside the box 11 to detect battery-related data; the moving mechanism is arranged at the bottom of the box 11 to drive the box 11 and the battery to move synchronously to the scrapping area. In the following, the specific connection method and function of each of the above mechanisms of the battery testing device according to the utility model will be described in detail.

[0033] In this embodiment, if Figure 1 As shown, the box 11 is formed into a rectangular parallelepiped structure to be more suitable for the shape and structure of the battery; an opening is formed at the top of the box 11 to facilitate the insertion and removal of the battery. In addition, the detection mechanism in this embodiment includes a drop detection unit for detecting the drop force of the battery and an integrated detection unit for detecting parameters such as battery resistance, current, and temperature, and the drop detection unit and the integrated detection unit are both located inside the box 11.

[0034] Specifically, Figure 1 As shown, the drop detection unit includes a lifting plate 201 and a plurality of hydraulic parts (not shown in the figure), the fixed end of the hydraulic part is arranged at the bottom of the box body 11, and the movable end of the hydraulic part is connected to the bottom of the lifting plate 201, so that the lifting plate 201 can be raised or lowered. There is no specific restriction on the specifications, quantity and setting position of the hydraulic parts, which should be determined comprehensively according to the actual situation, such as the size of the lifting plate 201, as long as the technical effect of driving the lifting plate 201 to rise and fall stably can be achieved. Furthermore, the lifting plate 201 is connected to an impact sensor 202, through which the falling force of the battery can be measured.

[0035] More specifically, a placement hole corresponding to the impact sensor 202 is formed at the top of the lifting plate 201, and the bottom of the impact sensor 202 is connected to the bottom of the placement hole through a spring (not shown in the figure). That is to say, in this embodiment, the impact sensor 202 is located in the placement hole, and due to the setting of the spring, when the impact sensor 202 is not subjected to force (that is, when the spring is in a natural state), its top protrudes from the top of the lifting plate 201, so that it can accurately measure the falling force of the battery; and when the battery is located at the top of the lifting plate 201, under the action of the battery's gravity, the spring is in a compressed state, that is, the top of the impact sensor 202 is flush with the top of the lifting plate 201, so that the stability of the battery can be guaranteed when it is subsequently moved.

[0036] It should be noted that there is no specific limit on the number and specifications of the springs, as long as the above technical effects can be achieved. It should be further noted that, considering the influence of the elastic force of the spring on the measurement result of the impact sensor 202, before assembling the impact sensor 202 with the lifting plate 201, the measurement value finally displayed by the impact sensor 202 can be adjusted through multiple experiments to ensure the accuracy of the battery drop force measurement.

[0037] In addition, in this embodiment, as shown in the figure, the integrated detection unit includes a first integrated detection component 203 and a second integrated detection component, and the first integrated detection component 203 and the second integrated detection component are respectively located at the two ends of the length direction of the box 11. When the hydraulic component is in a retracted state (that is, when the lifting plate 201 drives the battery to fall synchronously), the battery can be connected to the detection end of the first integrated detection component 203 and the second integrated detection component, so as to achieve the measurement of the resistance, current, voltage and temperature of the battery. It should be noted that the first integrated detection component 203 and the second integrated detection component can be existing sensors that can measure various parameters of the battery, so the measurement principle thereof will not be repeated.

[0038] As shown in the figure, a moving mechanism is also provided at the bottom of the box 11, which can drive the box 11 and the batteries that have been tested inside the box 11 to move synchronously to the scrapping area. In this embodiment, the moving mechanism is formed as a slider 4, and two sliders 4 are distributed at both ends of the width direction of the box 11. Correspondingly, a track corresponding to the slider 4 can be laid on the laboratory floor, so as to realize the automatic movement of the box 11 along the track to the scrapping area. The movement of objects along a specific track belongs to the existing technology in program control, so it will not be repeated. However, it is not limited to this, and the moving mechanism can also be formed as a plurality of moving wheels.

[0039] In addition, a spray assembly is also provided inside the box 11, and the spray assembly includes a high temperature sensor, a smoke sensor, and four spray parts 3 (which can be formed as nozzles) provided at the four top corners of the box 11, and the high temperature sensor and the smoke sensor are both connected to the spray part 3. In this way, when the battery falls and is damaged and a fire occurs, the high temperature sensor or the smoke sensor is triggered, so that the spray part 3 sprays carbon dioxide dry powder to extinguish the fire.

[0040] Furthermore, in order to ensure a clean experimental environment inside the box 11, a corresponding cover plate 12 is also provided at the opening of the box 11, and the cover plate 12 is rotatably connected to the box 11. Furthermore, although not shown in the figure, cylinders are provided at both ends of the length direction of the bottom of the cover plate 12, and the cover plate 12 can be opened and closed by the extension and contraction of the cylinders.

[0041] It should be noted that the box 11 is also provided with a control unit (which can be formed as a PCB board), which is communicatively connected or electrically connected to the above-mentioned moving mechanism, cylinder and hydraulic parts; in addition, the box 11 is also provided with a display screen which is communicatively connected to the above-mentioned detection mechanism so as to display the data measured by the detection mechanism, and the display screen can be set on the outer wall of the box 11.

[0042] According to the battery testing device of the utility model, the control unit controls the cylinder to open the cover 12 of the box 11, and the existing equipment is used to control the battery to fall into the box 11 at a preset height, and then the drop detection unit and the integrated detection unit in the detection mechanism respectively measure the drop force and related parameters of the battery, and the measured data can be displayed on the display screen; after the measurement, the cover 12 is closed, and then the box 11 and the battery are synchronously moved to the scrapping area through the moving mechanism. In this way, through the battery testing device in the utility model, the battery-related parameters can be directly tested, which saves the waiting time, that is, the detection efficiency is effectively improved; in addition, moving the battery through the moving mechanism after the test is safer and more efficient than the existing method of manually moving the battery.

[0043] Finally, it should be noted that the above-described embodiments are only specific implementation methods of the present application, which are used to illustrate the technical solutions of the present application, rather than to limit them. The protection scope of the present application is not limited thereto. Although the present application is described in detail with reference to the above-described embodiments, ordinary technicians in the field should understand that any technician familiar with the technical field can still modify the technical solutions recorded in the above-described embodiments within the technical scope disclosed in the present application, or can easily think of changes, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
