[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Reference Figure 1-Figure 5 A new energy vehicle battery bottom shell impact test device includes an impact mechanism 1 equipped with an impact head, a detection platform 2 is fixedly connected to the lower surface of the impact mechanism 1, a detection groove 3 is opened in the center of the upper surface of the detection platform 2, the interior of the detection groove 3 is connected to the lower end of the detection platform 2, and a detection mechanism is installed on the inner wall of the detection groove 3, and the detection mechanism includes a support plate 4.

[0026] In order to support the battery bottom shell, a rotating shaft 41 is fixedly inserted on the lower end surface of the support plate 4, and both ends of the rotating shaft 41 are rotatably connected to the inner wall of the detection groove 3 through bearings. A limiting groove is provided on the lower surface of the detection platform 2, and the support plate 4 is located in the limiting groove. The lower surface of the support plate 4 is slidably connected with a hinge seat 42, and the upper end of the hinge seat 42 is slidably connected to the inner wall of the limiting groove through a limiting block. The support plate 4 is movably installed by the rotating shaft 41, so as to facilitate the deflection of the support plate 4, and a cylinder 43 is fixedly installed on the inner side wall of the lower end of the detection platform 2. The top of the piston end of the cylinder 43 is hinged to the lower end of the hinge seat 42 through a rotating shaft. The cylinder 43 and the impact mechanism 1 are both located on the same side of the rotating shaft 41. While the cylinder 43 is used to support the support plate 4, the support plate 4 is deflected by the extension of the piston end on the surface of the cylinder 43, so as to facilitate the control of the deflection of the support plate 4.

[0027] In order to assist in unloading the battery bottom shell, a slide groove is opened on the inner wall of the detection groove 3, and a movable rod 44 is slidably connected to the inner wall of the slide groove. A cleaning cylinder 45 is fixedly sleeved on the surface of the movable rod 44, and the cleaning cylinder 45 is composed of a plastic cylinder wrapped with a cleaning cotton cloth. The cleaning cylinder 45 is sleeved on the surface of the movable rod 44, so that the friction between the cleaning cylinder 45 and the surface of one side of the support plate 4 is facilitated to clean the surface of one side of the support plate 4. Both ends of the movable rod 44 are fixedly connected with a slider 46, and the side wall surface of the slider 46 is fixedly connected with a tension spring 47. The slider 46 and the tension spring 47 are both located inside the slide groove, and the end of the tension spring 47 is fixedly connected to the inner wall of one end of the slide groove. When the cleaning cylinder 45 is installed on the upper surface of the support plate 4, the tension spring 47 converges the movable rod 44 through the slider 46, so as to prevent the movable rod 44 from approaching the middle part of the support plate 4 and affecting the placement of the battery bottom shell.

[0028] By installing a detection mechanism below the impact mechanism 1, the battery bottom shell is placed on the support plate 4 in the detection mechanism, and the deflection of the support plate 4 is controlled by the cylinder 43 in the detection mechanism. The support plate 4 is horizontally supported by the cylinder 43, so that the battery bottom shell cooperates with the impact mechanism 1 for detection, and after the detection is completed, the battery bottom shell is pushed downward by the deflection of the support plate 4, and one side of the battery bottom shell is pushed by the cleaning cylinder 45 to promote the unloading of the clean battery bottom shell.

[0029] A collecting box 5 is installed at the lower end of the testing platform 2. The collecting box 5 and the cylinder 43 are respectively located on both sides of the rotating shaft 41. Walking wheels 6 are installed on the lower surface of the collecting box 5. The collecting box 5 is used to collect the battery bottom shell that slides out, so as to facilitate recycling.

[0030] Working principle:

[0031] The cylinder 43 is started, and the piston end of the cylinder 43 drives the support plate 4 to be horizontal through the hinge seat 42, and the cylinder 43 is locked, and the battery bottom shell is placed on the upper surface of the support plate 4, and the impact mechanism 1 performs an impact test on the battery bottom shell;

[0032] After the test, the cylinder 43 is started, and the piston end of the cylinder 43 drives the support plate 4 to deflect through the hinge seat 42. At the same time, the upward deflected edge of the support plate 4 drives the cleaning cylinder 45 to slide on the surface of the support plate 4, and the movable rod 44 slides in the slide groove. The tension spring 47 is stretched, and the cleaning cylinder 45 wipes the surface of one side of the support plate 4 while squeezing the battery bottom shell. The battery bottom shell enters the collection box 5 from the gap on the side of the downward deflected support plate 4.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
