[0026] In view of the problem that the existing waterproof test of new energy automobile battery cannot accurately capture the failure node, the embodiment of the present disclosure provides a new energy automobile battery automatic detection device, as shown in Figures 1 to 4 It includes lifting assembly 1, clamping assembly 2 and detection assembly 3, the clamping assembly 2 is fixedly installed below the lifting assembly 1, the detection assembly 3 is fixedly installed below the clamping assembly 2, the lifting assembly 1 drives the clamping assembly 2 to move longitudinally into the inside of the detection assembly 3, and the longitudinal movement of the lifting assembly 1 and the clamping assembly 2 cooperates with the detection assembly 3 to carry out graded waterproof test.

[0027] As shown in Figure 1 The lifting assembly 1 includes base 11, electric push rod 12 and connecting plate 13, the base 11 is L-shaped structure and the electric push rod 12 is fixedly installed vertically on the top of the ground, the connecting plate 13 is fixedly installed at the lower end of the electric push rod 12.

[0028] When the waterproof test of the automobile battery is carried out, the electric push rod 12 on the base 11 is started to drive the connecting plate 13 to move longitudinally, so as to drive the clamping assembly 2 below the connecting plate 13 and the automobile battery to move longitudinally into the detection assembly 3.

[0029] As shown in Figure 3 And 4 The clamping assembly 2 includes frame 21, drive body 22, bidirectional screw rod 23, sliding block 24 and clamping body 25, the frame 21 is fixedly installed parallel to the ground below the connecting plate 13, the drive body 22 is fixedly installed at any one end of the frame 21, the bidirectional screw rod 23 is rotatably installed below the frame 21 and coaxially fixed with the drive body 22, the sliding block 24 is rotatably installed on the surface of the bidirectional screw rod 23, and the clamping body 25 is fixedly installed below the sliding block 24.

[0030] It should be noted that the surface of the bidirectional screw rod 23 is provided with two end threads with opposite rotation directions and symmetry, so that the sliding block 24 relatively approaches or moves away during rotation to clamp or release clamping. The drive body 22 adopts the motor in the prior art, in addition to this, any structure capable of driving the bidirectional screw rod 23 to rotate can also be adopted.

[0031] Before the waterproof test of the automobile battery, first start the drive body 22 to drive the bidirectional screw rod 23 to rotate, so as to drive the sliding block 24 and the clamping body 25 to approach each other and clamp the automobile battery, and then the electric push rod 12 on the base 11 drives the connecting plate 13 to move longitudinally, so as to drive the clamping assembly 2 below the connecting plate 13 and the automobile battery to move longitudinally into the detection assembly 3. After the waterproof test of the automobile battery is completed, the electric push rod 12 drives the connecting plate 13 and the clamping assembly 2 to move upward and away from the detection assembly 3, and then the drive body 22 reversely rotates to drive the bidirectional screw rod 23 to reversely rotate so that the sliding block 24 and the clamping body 25 move away from each other to release the clamping of the automobile battery.

[0032] As shown in Figure 4 , the clamping body 25 is in L-shaped structure. The L-shaped clamping body 25 can stably clamp the automobile battery, thereby facilitating to ensure that the automobile battery remains stable during the movement and detection.

[0033] As shown in Figure 2 and 3 , the detection assembly 3 includes a cylinder body 31, an annular pipe 32, a branch pipe 33 and a nozzle 34, the cylinder body 31 is fixedly installed below the clamping assembly 2, the annular pipe 32 is fixedly installed above the cylinder body 31, a plurality of branch pipes 33 are installed in an annular array on the surface of the annular pipe 32, the nozzle 34 is fixedly installed at the end of the branch pipe 33, and the annular pipe 32 is fixedly communicated with a water delivery pipe 35 and a pump body 36 in the longitudinal direction.

[0034] It should be noted that the cylinder body 31 contains liquid inside.

[0035] It should be noted that one end of the water delivery pipe 35 is communicated with the annular pipe 32, and the other end is immersed below the liquid level in the cylinder body 31. The pump body 36 is a submersible pump which can be directly installed below the liquid level inside the cylinder body 31.

[0036] During the clamping of the automobile battery and the longitudinal movement driven by the electric push rod 12 into the cylinder body 31, when moving to the upper part of the cylinder body 31, the pump body 36 starts to suck and deliver water into the water delivery pipe 35, so as to deliver water into the annular pipe 32 through the water delivery pipe 35, and then the water enters the nozzle 34 from the annular pipe 32 and sprays towards the automobile battery, thereby performing the spray test. After the automobile battery is subjected to the spray test in the area of the annular pipe 32, the electric push rod 12 continuously extends, thereby driving the clamping assembly 2 and the automobile battery to move below the liquid inside the cylinder body 31 to perform the short-time immersion test or the continuous submersion test.

[0037] It should be noted that when the clamping assembly 2 and the automobile battery enter the area of the annular pipe 32 for spray testing, the electric push rod 12 is temporarily stopped to make the clamping assembly 2 and the automobile battery stay in the area of the annular pipe 32 for spray testing. After the spray test is completed, the electric push rod 12 continues to extend to make the clamping assembly 2 and the automobile battery enter below the liquid level in the cylinder 31 for short-time immersion test or continuous diving test.

[0038] As shown in Figure 2 and 3 The annular pipe 32 is longitudinally arranged in multiple numbers, and the longitudinally arranged multiple annular pipes 32 are fixedly connected with each other through the water delivery pipe 35.

[0039] The longitudinally arranged multiple annular pipes 32 cooperate with the branch pipes 33 and the nozzles 34 to on the one hand extend the spray path, so that the water flow is fully developed under the action of gravity to form a stable “rain curtain” or “spray field”, avoiding the instability of impact intensity caused by the uneven initial speed of water flow in the short path, so that the water flow state is closer to natural rainfall, and the deviation of direct impact is reduced, the water flow contacts the battery surface at a more uniform speed and angle, and the detection authenticity is improved; on the other hand, it can realize omnidirectional detection without dead angle, and can simulate multi-directional rainfall to form superimposed water flow impact effect, which is closer to the case of multiple water flows acting at the same time in the real environment, which is beneficial to improve the detection effect.

[0040] The diameter of the longitudinally arranged nozzles 34 decreases from top to bottom along the axial direction. The nozzles 34 with decreasing diameters from top to bottom can make the water pressure sprayed by the nozzles 34 increase from top to bottom, so as to realize graded and progressive spray detection by cooperating with the electric push rod 12 to drive the clamping assembly 2 and the automobile battery to immerse in the liquid in the cylinder 31, which is convenient for simulating the progressive impact process of the automobile battery from daily light rain to heavy rain / water immersion, thereby facilitating accurate capture of failure nodes, and being beneficial to improve the effect of spray waterproofness test.

[0041] It should be noted that the decrease of the diameter of the nozzles 34 from top to bottom along the axial direction is to improve the flow rate and pressure by reducing the outlet cross-sectional area, and the change is minimal and the easiest.

[0042] It should be further noted that after the liquid in the cylinder 31 is sucked into the annular pipe 32 by the water pump and sprayed by the nozzles 34, the sprayed liquid can also naturally fall back into the cylinder 31, so as to realize water recycling, save resources and avoid waste of water resources.

[0043] As shown in Figure 4 The clamping body 25 is fixedly installed with a flexible layer 251 on the opposite surface.

[0044] The flexible layer 251 can avoid damage to the clamping body 25 when clamping the automobile battery, thereby ensuring safety when clamping the automobile battery for waterproof test, and facilitating to improve the safety and stability during the waterproof test, and avoiding excessive compression of the automobile battery to affect the waterproof test result.

[0045] It should be noted that the flexible layer 251 is made of rubber material.

[0046] The new energy automobile battery detection process of the embodiment of the present disclosure is as follows:

[0047] When the waterproof performance of the new energy automobile battery is automatically detected, the operator first starts the driving body 22 to drive the bidirectional screw rod 23 to rotate, thereby driving the sliding block 24 and the clamping body 25 to approach each other and clamp the automobile battery, and then the electric push rod 12 on the base 11 is started to drive the connecting plate 13 to move longitudinally, thereby driving the clamping assembly 2 below the connecting plate 13 and the automobile battery to move longitudinally into the detection assembly 3.

[0048] During the longitudinal movement of the clamping assembly 2 and the automobile battery into the detection assembly 3, the clamping assembly 2 and the automobile battery first enter the area where the annular pipe 32 is located, so that the pump body 36 is started to suck water into and deliver to the water delivery pipe 35, thereby delivering water to the annular pipe 32 through the water delivery pipe 35, and then the water enters the nozzle 34 from the annular pipe 32 and sprays towards the automobile battery, thereby performing the spray test.

[0049] When the clamping assembly 2 and the automobile battery are located in the annular pipe 32 area for spray test, the longitudinal multiple annular pipes 32 cooperate with the branch pipes 33 and the nozzles 34 to prolong the spray path on the one hand, and to perform dead angle-free detection on the other hand, thereby simulating multi-directional natural rainfall and forming superimposed water flow impact, which is beneficial to improve the detection effect. Moreover, the diameters of the longitudinal nozzles 34 decrease from top to bottom along the axial direction, which can also cooperate with the electric push rod 12 to drive the clamping assembly 2 and the automobile battery to immerse in the liquid in the cylinder 31 to realize the staged and progressive spray test, thereby facilitating to simulate the progressive impact process of the automobile battery from daily light rain to heavy rain / water immersion, so as to facilitate to accurately capture the failure node, and is beneficial to improve the effect of the waterproof test.

[0050] After the waterproof test is completed, the electric push rod 12 is retracted to drive the clamping assembly 2 and the automobile battery to move upward and leave the detection assembly 3, and then the driving body 22 is reversely rotated to drive the bidirectional screw rod 23 to reversely rotate so that the sliding block 24 and the clamping body 25 move away from each other to release the clamping of the automobile battery.

[0051] The person skilled in the art should understand that the utility model is not limited by the above-mentioned embodiments, the above-mentioned embodiments and the description are only for explaining the principle of the utility model, and various changes and improvements can be made to the utility model without departing from the spirit and scope of the utility model, and these changes and improvements all fall within the scope of the utility model claimed for protection. The scope of protection of the utility model is defined by the appended claims and their equivalents.
