DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1 and Figure 2As shown, a battery thermal management test fixture includes a support base 1, a fixing component 2 is fixedly installed on the left and right parts of the upper end of the support base 1, a cooling component 3 is fixedly installed on the upper rear part of the support base 1, and an adjustment range component 4 is fixedly installed on the left and right positions of the upper rear part of the support base 1.

[0027] The battery module can be quickly fixed on the rack 212 by the fixing component 2, and the fixing accuracy is high and the operation is convenient, which improves the overall practicality of the tooling. The battery in thermal management can be cooled by the cooling component 3, and the cooling system disperses the heat to reduce the risk of thermal runaway of the battery. The adjustment range component 4 can not only expand the range of battery cooling, but also adjust the blowing range of several air cooling heads 34 according to battery modules of different sizes, thereby improving the flexibility and accuracy of subsequent tests.

[0028] like Figure 2 , Figure 3 and Figure 4 As shown, the fixing assembly 2 includes an electric push rod 21, the outer wall of the electric push rod 21 is fixedly installed at the left position of the rear lower end of the support seat 1, a slide groove 22 is opened at the rear lower end of the support seat 1, and a slider 23 is slidably connected to the inner wall of the slide groove 22. A rack 24 is fixedly installed at the lower end of the slider 23, and the rear side of the rack 24 is fixedly connected to the output end of the electric push rod 21.

[0029] Through the output end of the electric push rod 21 , the rack 24 slides in the slide groove 22 through the slider 23 and moves left and right.

[0030] like Figure 3 and Figure 4 As shown, a rotating shaft 25 which passes through the top of the supporting base 1 is rotatably connected to the middle part of the upper end of the supporting base 1, a gear 26 is fixedly sleeved on the bottom of the outer wall of the rotating shaft 25, and the outer surface of the gear 26 is meshed with the front side of the rack 24. A storage groove is opened in the middle part of the upper end of the supporting base 1, a turntable 27 is fixedly sleeved on the top of the outer wall of the rotating shaft 25, and the outer wall of the turntable 27 is movably sleeved with the inner wall of the storage groove.

[0031] Through the movement of the rack 24, the gear 1 26 is meshed with the rack 24 to drive the turntable 27 to rotate, so that the turntable 27 can rotate a certain angle in the storage slot.

[0032] like Figure 3 As shown, the left and right positions at the upper edge of the turntable 27 are rotatably connected to the turntable 27, and the upper ends of the two turntables 28 are rotatably connected to the sides away from each other. The two fixed plates 29 are provided with a plurality of linearly arranged strip grooves on the opposite sides. The storage rack 212 is fixedly installed in the middle of the upper end of the support seat 1, and the storage rack 212 is located above the turntable 27.

[0033] By rotating the turntable 27, one end of the two rotating rods 28 rotates around the turntable, and the other end pulls the two fixing plates 29 closer to or away from each other, so that the battery module can be fixed on the storage rack 212. The several strip grooves opened on the two fixing plates 29 reduce the contact area between the two fixing plates 29 and the surface of the battery module, preventing the two fixing plates 29 from excessively contacting each other and affecting the overall heat dissipation of the battery module.

[0034] like Figure 3 As shown, connecting blocks 210 are fixedly installed at the front and rear bottoms of the two fixing plates 29 , sliding rods 211 are fixedly installed at the front and rear parts of the upper end of the support seat 1 , and the inner walls of four adjacent connecting blocks 210 are slidably connected to the outer walls of the two sliding rods 211 .

[0035] When the two fixed plates 29 are driven by the two rotating rods 28 , the corresponding connecting blocks 210 slide on the two sliding rods 211 respectively, and the cooperation between the four adjacent connecting blocks 210 and the two sliding rods 211 has a limiting effect on the movement of the two fixed plates 29 .

[0036] like Figure 5 As shown, the cooling assembly 3 includes a blower 31, the lower end of the blower 31 is fixedly installed on the upper rear part of the support base 1, an air supply pipe 32 is fixedly installed on the output end of the blower 31, an air supply pipe 33 is fixedly installed on the end of the air supply pipe 32 away from the blower 31, and a plurality of linearly arranged air cooling heads 34 are fixedly installed on the front part of the outer wall of the air supply pipe 33.

[0037] The blower 31 is an existing mechanism, which operates eccentrically through a rotor built into a cylinder. When the rotor rotates at a high speed, the volume between the blades in the rotor slot changes, allowing the blower 31 to suck in air, which is then compressed and transferred to the air supply pipe 33 through the air duct 32, and then acted on the surface of the battery module by a number of air cooling heads 34.

[0038] like Figure 1 , Figure 2 and Figure 6 As shown, the adjustment range assembly 4 includes two mounting plates 41, the lower ends of the two mounting plates 41 are fixedly installed at the left and right positions of the rear part of the upper end of the support seat 1, an adjusting screw 42 is rotatably connected to the right rear part of the left mounting plate 41, and a moving block 43 is threadedly connected to the outer wall of the adjusting screw 42, a moving groove 44 is opened at the left rear part of the left mounting plate 41, and a driving block 45 is slidably connected to the inner wall of the moving groove 44, the right side of the driving block 45 is fixedly connected to the left side of the moving block 43, and a driving rack 46 is fixedly installed on the left side of the driving block 45.

[0039] By rotating the adjusting screw 42 , the moving block 43 drives the driving block 45 to move through the threaded connection with the adjusting screw 42 , so that the driving block 45 slides in the moving groove 44 and drives the driving rack 46 to move up and down.

[0040] like Figure 6 As shown, connecting rods 47 are fixedly installed on the left and right ends of the air supply duct 33. The right end of the right connecting rod 47 is rotatably connected to the left top of the right mounting plate 41. The left part of the outer wall of the left connecting rod 47 passes through the left part of the left mounting plate 41 and is fixedly sleeved with gear 2 48. The outer surface of gear 2 48 is meshed with the front side of the driving rack 46.

[0041] Through the movement of the driving rack 46, the gear 2 48 meshes with the driving rack 46 to drive the left connecting rod 47 to rotate, thereby rotating the air supply pipe 33, and further allowing the plurality of air cooling heads 34 to adjust the air cooling range according to the actual situation of the battery module.

[0042] The working principle of the utility model is as follows: the staff places the battery module to be tested on the storage rack 212, and starts the electric push rod 21. The output end of the electric push rod 21 drives the rack 24 to move, and the gear 26 drives the rotating shaft 25 to rotate by meshing with the rack 24, and the turntable 27 rotates accordingly. One end of the two rotating rods 28 rotates around the turntable 27, and the other end drives the two fixing plates 29 to move closer to each other to limit the battery module.

[0043] In subsequent tests of the battery module, its internal temperature gradually increases. When the temperature of the battery module exceeds the set upper limit threshold, the blower 31 automatically starts, sucks in compressed air and transfers it to the air supply pipe 33 through the air supply pipe 32. Finally, a number of air cooling heads 34 act on the surface of the battery module.

[0044] At the same time, the staff can rotate the adjusting screw 42, and the moving block 43 drives the driving block 45 and the driving rack 46 to move by being threadedly connected with the adjusting screw 42. The gear 2 48 drives the air supply pipe 33 to rotate by meshing with the driving rack 46. The air supply pipe 33 drives several air cooling heads 34 to rotate, thereby expanding the air cooling range of the battery module surface and making the temperature distribution uniform during the battery module test.

[0045] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
