Specific Embodiments

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model but are not used to limit the scope of the present utility model.

[0023] Embodiment 1:

[0024] Referring to Figures 1 - 6 , an automotive lithium battery height detection device includes a bottom plate 1. Above the bottom plate 1, a moving plate 3 is provided. Two sets of through slots are symmetrically opened on the moving plate 3. Moving rods 301 are slidably arranged in the through slots. Sliders 303 are symmetrically arranged on the moving rods 301. A chute for cooperating with the sliders 303 is opened on the moving plate 3. The sliders 303 and the moving plate 3 are connected by a tension spring 304. A standard block 305 for cooperating with the moving rods 301 is arranged at the upper end of the moving plate 3;

[0025] A support plate 2 is arranged on the bottom plate 1. An electric hydraulic rod 4 is arranged at the upper end of the support plate 2. The telescopic end of the electric hydraulic rod 4 is fixedly connected to the moving plate 3;

[0026] A fixed frame is arranged on the bottom plate 1;

[0027] The fixed frame includes a U-shaped frame 5 and a baffle 6. The U-shaped frame 5 and the baffle 6 are rotatably connected. A U-shaped limit block 7 is arranged on one side of the U-shaped frame 5. Slots for cooperating with the U-shaped limit block 7 are opened on both the U-shaped frame 5 and the baffle 6;

[0028] When it is necessary to detect the height of the module lithium battery, take out the U-shaped limit block 7, move the baffle 6, place the module lithium battery into the U-shaped frame 5, then move the baffle 6, and insert the U-shaped limit block 7 into the slot to fix the baffle 6. Then, the electric hydraulic rod 4 extends to drive the moving plate 3 to move. When the moving plate 3 gradually moves downward, the moving rod 301 contacts the module lithium battery and then rises. When the moving plate 3 moves to a fixed position, at this time, the upper ends of all the moving rods 301 are lower than the upper end of the standard block 305, then the module lithium battery has a qualified height. And a scale is arranged on the standard block 305, and it is possible to judge whether the shell cover of the module lithium battery is inclined according to the height of all the moving rods 301;

[0029] After the detection is completed, the electric hydraulic rod 4 contracts, the moving plate 3 moves back, and under the action of the tension spring 304, the slider 303 drives the moving rod 301 to move back. At this time, take out the U-shaped limit block 7, move the baffle 6, and the module lithium battery can be taken out from the U-shaped frame 5 to replace other module lithium batteries to be detected;

[0030] Judge whether the height of the module lithium battery is qualified by the movement of the moving rod 301, and it can also judge whether the shell cover of the module lithium battery is tilted, reduce the measurement error, and effectively improve the accuracy and detection effect.

[0031] Embodiment 2:

[0032] Refer to Figures 1 - 6 , an automobile lithium battery height detection device, which is basically the same as Embodiment 1. Further, a first magnet 701 is arranged on the U-shaped limit block 7, and second magnets 8 are arranged in the slots of the U-shaped frame 5 and the baffle 6. By the close contact of the first magnet 701 and the second magnet 8, the U-shaped limit block 7 is prevented from moving out of the slot, affecting the fixation of the baffle 6.

[0033] The lower end of the moving rod 301 is rotatably connected with a pressing plate 302, which increases the contact area with the module lithium battery and makes the detection result more accurate.

[0034] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention.
