[0051] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0052] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the invention product is usually placed when in use, or the orientation or positional relationship commonly understood by those skilled in the art. Such terms are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0053] See also Figures 1 to 8 The present invention provides a technical solution: a new energy vehicle battery resistance external force detection device, comprising a detection chamber 1 and a detection terminal 2 arranged on the inner top wall of the detection chamber 1, the inner bottom wall of the detection chamber 1 is provided with a support table 3 for supporting and placing the new energy vehicle battery to be detected, and also includes: a protection structure 4, which is arranged on the detection terminal 2 for sealing and protecting the new energy vehicle battery; a locking structure 5, which is arranged on both sides of the supporting table 3 for locking the protection structure 4; a driving structure 6, which is arranged on the two inner walls of the detection chamber 1 for driving the locking structure 5 to achieve locking of the protection structure 4;

[0054] The detection terminal 2 includes a hydraulic telescopic arm 21 fixed to the top wall of the detection chamber 1 and a test terminal 22 connected to the output end of the hydraulic telescopic arm 21;

[0055] The test terminal 22 has a plurality of detection sensors, which are used to collect and transmit the test data in a timely manner when it falls and contacts the battery to perform an external force resistance test, so as to judge the situation of the external force resistance test. Since the test terminal 22 is a mature and perfect existing technology, it is not further elaborated in this application;

[0056] The protection structure 4 includes a protection shell 41 sleeved on the surface of the hydraulic telescopic arm 21, and a through groove 42 is formed on the surface of the protection shell 41 for the hydraulic telescopic arm 21 to pass through, wherein a support member 43 is fixed on the test terminal 22, and the outer diameter of the support member 43 is larger than the inner diameter of the through groove 42, and the test terminal 22 can synchronously drive the protection shell 41 to move through the support member 43 through the telescopic movement of the hydraulic telescopic arm 21. Since the test terminal 22 and the support member 43 thereon are both located below the protection shell 41 in the initial state, the test terminal 22 will not form a movement obstacle with the protection shell 41 during the process of moving down to detect the battery, and when the test terminal 22 moves down and completes the external force resistance test of the battery, at this time, since the protection shell 41 has moved down to protect the battery during the detection process, the test terminal 22 in the upward movement process will support the protection shell 41 through the support member 43 thereon to synchronously move upward, thereby realizing the synchronous reset of the protection shell 41 and the test terminal 22;

[0057] The protection structure 4 also includes a support base 44, and the protection shell 41 is buckled on the support base 44 to form a closed space for protecting the new energy vehicle battery. The support base 44 is fixed on the support table 3;

[0058] The support table 3 includes a support leg 31 fastened to the bottom wall of the detection chamber 1 by bolts and a support platform 32 arranged above the support leg 31, and an elastic member 33 is arranged between the support leg 31 and the support platform 32;

[0059] The support platform 32 includes a main cylinder 320 and a secondary cylinder 321, and a spring 322 is commonly connected between the main cylinder 320 and the secondary cylinder 321. The main cylinder 320 and the secondary cylinder 321 are respectively connected to the corresponding support legs 31 and the support platform 32;

[0060] The support base 44 is used to place the new energy vehicle battery to be tested. In actual application, a clamp (not shown in the figure) can also be set on the support base 44 to clamp the placed battery, so that it is more stable during the external force resistance test and is not prone to position deviation.

[0061] The locking structure 5 includes a support arm 50 connected to the side wall of the detection chamber 1 and a movable shaft 51 hinged to the inner side of the support arm 50, a locking arm 52 is fixed to the movable shaft 51, wherein both sides of the surface of the movable shaft 51 are sleeved with a torsion spring 53, one end of the torsion spring 53 is connected to the support arm 50 and the other end is connected to the corresponding locking arm 52, and the movable shaft 51 has a running tendency to flip inside the support arm 50 under the action of the torsion spring 53;

[0062] Elastic sheets 54 are fixed on both sides of the support arm 50. The elastic sheets 54 can stabilize the locking arm 52 in a horizontal state. A driving part 55 extends from one end of the locking arm 52.

[0063] Sliding grooves 410 are formed on both sides of the protective shell 41, and a locking groove 411 is formed on the bottom wall of the sliding groove 410. A locking block 56 adapted to the locking groove 411 is fixed to the end of the locking arm 52;

[0064] The driving structure 6 includes an electric push rod 61 fixed to the side wall of the detection chamber 1 and a side plate 62 connected to the output end of the electric push rod 61, an extension platform 63 is fixed to the top end of the side plate 62, and a tooth plate 64 is fixed to the bottom end of the side plate 62;

[0065] The driving structure 6 also includes a support plate 65 fixed to the side wall of the detection chamber 1 and a support rod 66 rotatably arranged on the support plate 65, triangular plates 67 are fixed to both ends of the support rod 66, and a toothed ring 68 for meshing with the toothed plate 64 is fixed to the middle of the support rod 66;

[0066] like Figure 1 , Figure 2 , Figure 4 As shown, in the initial state, that is, when the battery is not tested, the protective shell 41 is in a suspended support state, and the triangular plate 67 is in a support state for the support base 44. When the battery is tested for resistance to external forces, the following is formed: Figure 4 , Figure 5 , Figure 6 and Figure 7 The status shown;

[0067] like Figure 6 As shown, in order to ensure that the position of the protective shell 41 during the falling process is more accurate, a more consistent protection space can be formed with the supporting base 44 below, so that the telescopic rod 7 is set. Through the setting of the telescopic rod 7, the protective shell 41 during the falling process can fall in a vertical state with the horizontal plane, thereby ensuring the accuracy of the landing, ensuring the sealing of the protection space, and at the same time better cooperating with the outer locking structure 5 to form a locked state;

[0068] Before testing the battery of a new energy vehicle, the battery to be tested is placed on the top of the support base 44, and the test terminal 22 is driven downward by the hydraulic telescopic arm 21, so that the test terminal 22 applies an external force to the battery to achieve the test of resistance to external force. When spontaneous combustion occurs during the external force test of the battery, the electric push rod 61 is driven so that its output end drives the side plate 62 to slide in the direction away from the protective shell 41;

[0069] When the side plate 62 is sliding, the extension platform 63 on it will release the support for the protective shell 41, and the side plate 62 will also synchronously drive the toothed plate 64 at the bottom thereof to slide. During the sliding process, the toothed plate 64 will mesh with the corresponding toothed ring 68, and the meshed toothed ring 68 will drive the support rod 66 and the triangular plate 67 thereon to rotate, so that the sharp portion of the triangular plate 67 releases the support for the support platform 32. At this time, the support platform 32 is supported by the elastic member 33 and still maintains the initial height;

[0070] The protective shell 41 without support will fall vertically toward the support base 44. During the falling process, it will conflict with the driving part 55 on the locking arm 52 in the horizontal state. The locking arm 52 under the conflict will overcome the elastic limiting effect of the elastic sheet 54 and flip over. At the same time, the torsion spring 53 will cooperate to accelerate the flipping of the locking arm 52, so that the locking arm 52 and the locking block 56 thereon will fit the outer side of the protective shell 41 and gradually approach the sliding groove 410. When the protective shell 41 falls and contacts the support platform 32, the support platform 32 will move down to a certain height. During this downward movement, the end of the locking arm 52 will completely slide into the corresponding sliding groove 410, and at the same time, the locking block 56 on the locking arm 52 will be higher than the height of the locking groove 411.

[0071] After the protective shell 41 finishes moving down and the impact force is dispersed, the support platform 32 that has moved down can be supported by the spring 322 and can slide upward to reset. During the reset process, the height of the locking block 56 remains unchanged, and the continuously upward protective shell 41 and the locking groove 411 thereon will eventually form a locked state with the locking block 56. At this time, the support platform 32 remains in a relatively stable state, and the locking arm 52 is locked by the locking block 56 and cannot rotate outward to form a stable lock, so that it has a better protection effect on the battery, can effectively protect against explosions, etc., and avoids the situation where the protective shell 41 is easily separated from the support base 44.

[0072] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
