DETAILED DESCRIPTION

[0028] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0029] A new energy vehicle battery bracket bending strength testing device, such as Figure 1 and Figure 2 As shown, it includes a mounting base 1, a placement plate 2, a mounting frame 3, a bending mechanism 4 and a moving mechanism 5. The top of the mounting base 1 is connected to the placement plate 2, and the placement plate 2 is used to place the battery holder. The upper rear side of the mounting base 1 is connected to the mounting frame 3 by bolts. The mounting frame 3 is provided with a bending mechanism 4 for stamping the battery holder. The mounting base 1 is provided with a moving mechanism 5 for controlling the automatic movement of the battery holder and improving the stability of the battery holder.

[0030] Since the battery of a new energy vehicle has a certain weight, it will be shaken during the daily driving of the car. Therefore, the battery holder needs to have strong bending resistance to ensure support for the battery of the new energy vehicle. When the battery holder is subjected to a bending strength test, the battery holder is placed on the placement plate 2, and then the battery holder is pushed by the moving mechanism 5 so that the battery holder moves to the bottom of the bending mechanism 4, and then the bending mechanism 4 is started to perform a stamping test on the battery holder. After the test, the bending mechanism 4 is controlled to reset, and then the battery holder is sent out by controlling the moving mechanism 5.

[0031] like Figure 1 and Figure 3 As shown, the bending mechanism 4 includes a hydraulic cylinder 41, a pressing block 42, a fixing frame 43 and an anti-pressure block 44. The hydraulic cylinder 41 is connected to the lower front side of the mounting frame 3, and the pressing block 42 is connected to the telescopic end of the hydraulic cylinder 41. The bottom of the pressing block 42 is an arc-shaped structure, which can avoid cutting the battery bracket during the stamping process. The mounting frame 3 is connected to the inside of the fixing frame 43, and two anti-pressure blocks 44 are slidably connected to the fixing frame 43. The anti-pressure blocks 44 are both used to support the battery bracket.

[0032] When testing the bending strength of the battery holder, the battery holder is placed on the placement plate 2, and then the battery holder is pushed to the left so that the battery holder is placed between the tops of the pressure-resistant blocks 44. Then the hydraulic cylinder 41 is started, and the telescopic end of the hydraulic cylinder 41 extends downward, which will drive the lower pressure block 42 to move downward and perform a stamping test on the battery holder. The pressure-resistant block 44 can always support the battery holder, thereby assisting the stamping test to be completed smoothly. After the test, the telescopic end of the hydraulic cylinder 41 is controlled to retract and reset upward, so that the lower pressure block 42 moves upward and resets. Finally, the tested battery holder can be taken out. In summary, the telescopic end of the hydraulic cylinder 41 drives the lower pressure block 42 to move, thereby performing a stamping test on the battery holder, thereby achieving the effect of quickly testing the bending strength of the battery holder.

[0033] like Figure 1 and Figure 4 As shown, the moving mechanism 5 includes a dual-axis motor 51, a first synchronous belt 52, a first screw rod 53, a moving seat 54, a rotating block 55, a propulsion block 56, a torsion spring 57 and a stopper 58. The front part of the mounting seat 1 is connected to the dual-axis motor 51 by bolts. The left and right output shafts of the dual-axis motor 51 are connected to the first screw rod 53. Two first synchronous belts 52 are connected between the left and right output shafts of the dual-axis motor 51 and the first screw rod 53. The first screw rod 53 is threadedly connected to the moving seat 54. The moving seat 54 is slidably connected to the mounting seat 1. The movable seat 54 on the side is rotatably connected to a rotating block 55, and the rotating block 55 is rotatably connected to a propulsion block 56. Two torsion springs 57 are connected between the propulsion block 56 and the rotating block 55. The torsion springs 57 are all wound around the rotating block 55. The ends of the torsion springs 57 that are close to each other are connected to the propulsion block 56, and the ends of the torsion springs 57 that are away from each other are connected to the rotating block 55. A stop block 58 is connected to the movable seat 54 on the left side. The stop block 58 cooperates with the propulsion block 56 to clamp and fix the battery holder, thereby improving the stability of the battery holder.

[0034] When the battery holder needs to be tested for bending strength, the battery holder can be placed on the placement plate 2, and then the rotating block 55 is rotated backward, so that the pushing block 56 is rotated backward. If the pushing block 56 contacts the battery holder during the backward rotation, the pushing block 56 will rotate upward, and the torsion spring 57 will be subjected to a phase change until the battery holder moves into place. Under the action of the torsion spring 57, the pushing block 56 will rotate downward and reset, and cooperate with the stopper 58 to clamp the battery holder, thereby improving the stability of the battery holder. Then, the output shaft of the dual-axis motor 51 is controlled to rotate, so that the first synchronous belt 52 drives the first screw rod 53 to rotate. The rotation of the first screw rod 53 will drive the moving seat 54 to slide to the left, so that the stopper 58 and the pushing block 56 both move to the left, thereby pushing the battery holder. After the battery holder moves to the specified position, the dual-axis motor 51 is turned off, and the stopper is used to stop the battery holder. The cooperation between block 58 and push block 56 can improve the stability of the battery holder during inspection and avoid the battery holder from tilting during the stamping process. After the inspection is completed, the output shaft of the dual-axis motor 51 is controlled to rotate in the opposite direction, so that the movable seat 54 slides to the right and resets, and then the block 58 and the push block 56 move to the right, pushing the battery holder to the right to discharge after the inspection is completed, and finally the rotating block 55 is rotated forward and reset, so that the push block 56 moves forward and resets. In summary, the first screw rod 53 is driven to rotate by the output shaft of the dual-axis motor 51, so that the movable seat 54 moves automatically, thereby automatically transporting the battery holder. During the movement, the battery holder is clamped and fixed through the cooperation between the push block 56 and the block 58, making the movement of the battery holder more stable. During the stamping test, the block 58 and the push block 56 can clamp the battery holder to avoid the battery holder from tilting during the stamping process.

[0035] like Figure 1 、 Figure 5 and Figure 6 As shown, it also includes an adjusting mechanism 6, which includes a worm 61, a rotating shaft 62, a worm wheel 63, a second synchronous belt 64 and a second screw 65. The lower part of the mounting seat 1 is rotatably connected to the worm 61, and the front side of the worm 61 has a rotating handle, which makes it easy for people to control the worm 61. The bottom of the fixed frame 43 is rotatably connected to the rotating shaft 62, and the worm wheel 63 is connected to the rotating shaft 62. The worm wheel 63 and the worm 61 are engaged with each other. The top of the fixed frame 43 is rotatably connected to the second screw 65, and the anti-pressure blocks 44 are all threadedly connected to the second screw 65. The second screw 65 and the rotating shaft 62 are connected by a second synchronous belt 64 through a synchronous wheel. The second synchronous belt 64 can make the second screw 65 rotate synchronously with the rotating shaft 62.

[0036] When it is necessary to adjust the distance between the two anti-pressure blocks 44, the worm 61 can be directly rotated to make the worm wheel 63 rotate. The rotation of the worm wheel 63 will drive the rotating shaft 62 to rotate. The rotation of the rotating shaft 62 will drive the second synchronous belt 64 to rotate. The rotation of the second synchronous belt 64 will drive the second screw rod 65 to rotate. The rotation of the second synchronous belt 64 will drive the second screw rod 65 to rotate, and the rotation of the second screw rod 65 will cause the anti-pressure blocks 44 to slide, thereby adjusting the distance between the anti-pressure blocks 44, and then adjusting the test area range of the battery holder. Repeating the above operation can continuously adjust the distance between the two anti-pressure blocks 44. In summary, by rotating the worm 61, the worm wheel 63 is rotated, and then the rotating shaft 62 drives the second synchronous belt 64 to operate. The second synchronous belt 64 will drive the second screw rod 65 to rotate, so that the distance between the two anti-pressure blocks 44 can be adjusted, and the range of the stamping test area of ​​the battery holder is adjusted, thereby improving the accuracy of the detection.

[0037] like Figure 1 and Figure 7 As shown, a clamping mechanism 7 is also included. The clamping mechanism 7 includes a slotted rod 71, a sliding frame 72 and a spring 73. The slotted rod 71 is connected to the left side of the rotating block 55. The sliding frame 72 is slidably connected to the stopper 58. Two springs 73 are connected between the sliding frame 72 and the stopper 58. The springs 73 are all wound around the sliding frame 72. The right ends of the springs 73 are connected to the sliding frame 72, and the left ends of the springs 73 are connected to the stopper 58. The sliding frame 72 is slidably connected to the slotted rod 71, and the sliding frame 72 can be pushed by the battery holder.

[0038] When the battery holder moves to the left, it will contact the sliding frame 72, thereby pushing the sliding frame 72 to the left. The spring 73 is compressed, and the sliding frame 72 sliding to the left will drive the slot rod 71 to rotate, thereby causing the rotating block 55 to rotate backward to clamp the battery holder. When the inspection is completed, the rotating block 55 is rotated forward and reset, thereby causing the sliding frame 72 to slide to the right and reset. At the same time, under the action of the spring 73, the battery holder is pushed to the right, making it easier for the inspector to remove the battery holder. In summary, the sliding frame 72 is pushed by the battery holder, so that the slot rod 71 drives the rotating block 55 to rotate, so that the propulsion block 56 can clamp the battery holder, reducing the inspection personnel's manual rotation of the rotating block 55 and improving the inspection efficiency.

[0039] like Figure 1 and Figure 8As shown, it also includes a propulsion mechanism 8, which includes an electric push rod 81, a push plate 82 and a block 83. The right part of the mounting base 1 is connected to the electric push rod 81 by bolts, and the telescopic end of the electric push rod 81 is rotatably connected to the push plate 82, and the push plate 82 can contact the battery bracket. The push plate 82 is slidably connected to the block 83, and the block 83 can limit the push plate 82. The block 83 is an L-shaped structure, which is convenient for the operator to push and can prevent the block 83 itself from sliding out.

[0040] When the battery holder needs to be pushed to the left for feeding, the push plate 82 can be turned up by rotating counterclockwise when the battery holder is placed on the placement plate 2, and then the block 83 can be pushed upward so that the block 83 limits the push plate 82, and then the telescopic end of the electric push rod 81 is started to retract to the left, so that the push plate 82 pushes the battery holder to slide to the left for feeding. After the pushing is completed, the block 83 is pulled down to reset, and then the push plate 82 is rotated clockwise to reset, and finally the telescopic end of the electric push rod 81 is controlled to extend to the right and reset. In summary, the push plate 82 is driven to move to the left by the telescopic end of the electric push rod 81, thereby pushing the battery holder and assisting the battery holder in feeding.

[0041] like Figure 1 and Figure 9 As shown, a protective mechanism 9 is also included, and the protective mechanism 9 includes a first protective plate 91 and a second protective plate 92. The first protective plate 91 is connected to the front side of the mounting base 1, and the second protective plates 92 are connected to the left and right sides of the first protective plate 91. The first protective plate 91 and the second protective plate 92 can both prevent debris from splashing during the stamping test of the battery bracket.

[0042] When the battery holder is subjected to a compressive impact test, the battery holder may be broken due to the stamping, and the broken battery holder may generate flying debris. At this time, both the first protective plate 91 and the second protective plate 92 can protect the flying debris.

Any equivalent substitutions made within the principles of the present invention are intended to be included within the scope of protection of the present invention. Any content not elaborated in detail herein is already known to those skilled in the art.
