Description

Technical Field

[0002] At present, new energy vehicles have been widely promoted. As the power source of new energy batteries, the safety issues of lithium batteries have always been highly emphasized. It is necessary to continuously conduct experimental tests on lithium batteries to understand the working conditions of battery packs in different environments. Factories producing lithium batteries need to conduct impact tests on specific models of lithium batteries produced.

[0003] Impact tests include ordinary impact tests and needle impact tests. The needle impact test can test the state of lithium batteries when they are punctured by sharp objects. Most of the existing battery impact testing devices can only conduct one type of impact test on lithium batteries, and the tested batteries are also divided into columnar and cuboid shapes. If the test type needs to be changed, technicians need to manually replace the collision objects, which is rather troublesome. Moreover, most of the existing battery impact testing devices are not easy to control the impact force during collision, and the clamping and fixing of lithium batteries and the opening and closing of the protection device need to be manually operated, with low automation, increasing the workload of technicians.

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below with reference to specific diagrams. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0030] Please refer to Figures 1 - 11 , an embodiment of the present invention provides a technical solution: a new energy lithium battery impact test device, including a test bench 1 and a support column 2. The support column 2 is fixedly connected to the lower surface of the test bench 1. An outer shell 3 can be fixedly connected to the upper surface of the test bench 1. Speed regulating mechanisms 5 are provided on both opposite outer walls of the outer shell 3. Docking mechanisms 6 are provided on both opposite sides of the upper surface of the test bench 1. A striker 9 and a collision block 10 are provided on both sides of the top of the inner cavity of the outer shell 3. A rotating cover 4 is slidably connected to one end of the upper surface of the test bench 1. A linkage mechanism 7 is provided in the test bench 1;

[0031] The linkage mechanism 7 includes a transmission gear 71 provided on the inner wall of the lower end of the rotating cover 4. A first gear 72 and a third gear 74 are meshed and connected to one side of the transmission gear 71. A second gear 73 is meshed and connected to the other side of the first gear 72. The first gear 72, the second gear 73, and the third gear 74 are all rotatably provided in the test bench 1. A turntable 8 is rotatably provided on the upper surface of the test bench 1 in the inner cavity of the outer shell 3. A toothed ring 75 is rotatably provided on the outer wall of the lower end of the turntable 8. The toothed ring 75 is meshed and connected to the second gear 73. A fourth gear 78 is meshed and connected inside the toothed ring 75. A fifth gear 710 is meshed and connected to the upper side of the fourth gear 78. Three fifth gears 710 are provided on the other side of the fifth gear 710. And the middle fifth gear 710 is meshed and connected to the fifth gears 710 on both sides. A rotating shaft 79 is fixedly connected between the middle fifth gear 710 and the fifth gear 710 on the other side. Threaded rods 711 are fixedly connected to the centers of the fifth gears 710 on both sides. An arc-shaped clamping block 712 is threadedly connected to the outer wall of one of the threaded rods 711. A square clamping block 713 is threadedly connected to the outer wall of the other threaded rod 711. The fifth gear 710, the rotating shaft 79, and the threaded rod 711 are all rotatably connected in the turntable 8.

[0032] Specifically, when an impact test needs to be performed on a lithium battery, the third motor 77 is started to open the rotating cover 4. After placing the corresponding type of lithium battery, the striker 9 and the collision block 10 are located on two opposite sides at the center of the cavity of the outer shell 3. When the turntable 8 rotates, the rotating cover 4 rotates to one side through the rotating groove 12. Then, one end of the transmission tooth 71 on the inner wall of the rotating cover 4 will disengage from the first gear 72, and one end of the transmission tooth 71 will be located between the first gear 72 and the third gear 74. If it is necessary to change the type of impact test, the second motor 76 is started to rotate the turntable 8 by 180 degrees, and then the third motor 77 is started again to reverse the third motor 77, so that the rotating cover 4 blocks the opening of the outer shell 3. When the rotating cover 4 closes, through the cooperation of the first gear 72, the second gear 73, the toothed ring 75, the fourth gear 78, the rotating shaft 79, the threaded rod 711 and each fifth gear 710, the arc-shaped clamping block 712 and the square clamping block 713 move to one side, and then the lithium battery is clamped and fixed. Then, the docking mechanism 6 is started. Under the action of gravity, the collision block 10 or the striker 9 will fall, and then hit the lithium battery to be tested. The impact force during the collision can be changed by the speed regulating mechanism 5.

[0033] In another embodiment provided by the present invention, the speed regulating mechanism 5 includes two pull ropes 51, and the two pull ropes 51 are respectively fixedly connected to the striker 9 and the collision block 10. A fixed block 52 and a plurality of counterweight blocks 54 are slidably arranged on the outer walls of two opposite sides of the outer shell 3. One end of the outer wall of the fixed block 52 is connected with an insertion block 53. Slots 55 are opened on the outer walls of the fixed block 52 and the counterweight blocks 54. A baffle 56 is slidably arranged inside the outer wall of the outer shell 3 below the counterweight block 54, and a first spring 57 is fixedly connected between the lower surface of the baffle 56 and the outer shell 3.

[0034] Specifically, if it is necessary to change the impact force during the collision, first insert the insertion block 53 into the slot 55 of the corresponding counterweight block 54. The lower the insertion position of the insertion block 53, the more counterweight blocks 54 there are, and the smaller the initial velocity of the collision block 10 or the striker 9 when it falls, and the smaller the impact force.

[0035] In another embodiment provided by the present invention, the docking mechanism 6 includes fixing seats 61 fixedly connected to two opposite sides of the upper surface of the test bench 1. The inner wall of the vertical end of the fixing seat 61 is bolted with an electric push rod 62. The other end of the electric push rod 62 is fixedly connected with a first motor 63. The lower end of the first motor 63 is fixedly connected with a sliding plate 68. The sliding plate 68 is slidably arranged on the upper surface of the horizontal end of the fixing seat 61. The output end of the first motor 63 is fixedly connected with a fixing plate 67. On the other side of the fixing plate 67, there is a wire winding column 64. One end of the wire winding column 64 is rotatably connected inside the housing 3. A pulling rope 51 is wound around the outer wall of the end of the wire winding column 64 located inside the housing 3. Semi-circular protrusions 65 are fixedly connected to the opposite side walls of the fixing plate 67 and the wire winding column 64. Plug-in components 66 are arranged at both the upper and lower ends of the semi-circular protrusion 65 on the side wall of the fixing plate 67 close to the wire winding column 64. Limiting grooves 69 are opened at both the upper and lower ends of the semi-circular protrusion 65 on the side wall of the wire winding column 64 close to the fixing plate 67.

[0036] Specifically, when the electric push rod 62 is started to separate the fixing plate 67 from the wire winding column 64, the plug-in component 66 will disengage from the limiting groove 69. Under the action of gravity, the collision block 10 or the firing pin 9 will fall. When it is necessary to wind up the pulling rope 51, start the electric push rod 62 to move the fixing plate 67 close to the wire winding column 64. When the semi-circular protrusions 65 on both sides are in contact with each other, the wire winding column 64 will rotate, so that the plug-in component 66 is inserted into the corresponding limiting groove 69. Then rotate the first motor 63 to wind up the pulling rope 51 by the wire winding column 64 and pull the collision block 10 or the firing pin 9 back to the upper side again.

[0037] In another embodiment provided by the present invention, the plug-in component 66 includes a sleeve block 661 fixedly connected to the side wall of the fixing plate 67. A plug rod 662 is movably inserted into the sleeve block 661. A second spring 663 is fixedly connected between one end of the plug rod 662 and the sleeve block 661.

[0038] Specifically, after the fixing plate 67 approaches the wire winding column 64, the plug rod 662 abuts against one end of the wire winding column 64. After the wire winding column 64 rotates, the plug rod 662 is inserted into the limiting groove 69 to connect the fixing plate 67 and the wire winding column 64.

[0039] In another embodiment provided by the present invention, the pulling rope 51 is fixedly connected to the fixing block 52, and the pulling rope 51 penetrates through the counterweight 54.

[0040] In another embodiment provided by the present invention, the test bench 1 includes a disc 11, and a rotating groove 12 and a sliding groove 13 are opened on the disc 11.

[0041] In another embodiment provided by the present invention, a third motor 77 and a second motor 76 are respectively fixedly connected to the third gear 74 and the lower end of the turntable 8. The third motor 77 and the second motor 76 are both fixedly connected to the lower surface of the test bench 1.

[0042] In another embodiment provided by the present invention, the gear ring 75 includes a circular ring 752. Inner teeth 753 and outer teeth 751 are respectively provided on the inner wall and the outer wall of the circular ring 752. A rubber sheet is adhesively bonded to the outer wall of the circular ring 752 located inside the turntable 8. Two placement grooves are formed on the upper surface of the turntable 8, and an arc-shaped clamping block 712 and a square clamping block 713 are respectively and slidably arranged in the two placement grooves.

[0043] Specifically, after the rotating cover 4 is opened, the corresponding type of lithium battery is placed in the corresponding placement groove. The lithium battery is placed on the side of the placement groove away from the arc-shaped clamping block 712 or the square clamping block 713. When one end of the transmission gear 71 disengages from the first gear 72, if the turntable 8 needs to be rotated at this time, due to the rubber sheet provided, the friction between the gear ring 75 and the turntable 8 can be increased, so that when the turntable 8 rotates, it drives the gear ring 75 to rotate, and the arc-shaped clamping block 712 and the square clamping block 713 do not move when the turntable 8 rotates.

[0044] Working principle: When it is necessary to conduct an impact test on a lithium battery, start the third motor 77 to open the rotating cover 4. Then, place the corresponding type of lithium battery into the corresponding placement groove. Place the lithium battery on the side of the placement groove away from the arc-shaped clamping block 712 or the square clamping block 713. The impact pin 9 and the collision block 10 are located on two opposite sides at the center of the cavity of the outer shell 3. When the turntable 8 rotates, the rotating cover 4 rotates to one side through the rotating groove 12. Then, one end of the transmission gear 71 on the inner wall of the rotating cover 4 will disengage from the first gear 72, and one end of the transmission gear 71 will be located between the first gear 72 and the third gear 74. If it is necessary to change the type of impact test, start the second motor 76 to rotate the turntable 8 by 180 degrees, and then start the third motor 77 again to reverse the third motor 77, so that the rotating cover 4 blocks the opening of the outer shell 3. When the rotating cover 4 closes, through the cooperation of the first gear 72, the second gear 73, the toothed ring 75, the fourth gear 78, the rotating shaft 79, the threaded rod 711, and each fifth gear 710, the arc-shaped clamping block 712 and the square clamping block 713 move to one side, and then the lithium battery is clamped and fixed. Then, start the electric push rod 62 to separate the fixed disk 67 from the wire winding column 64, then the plug-in assembly 66 will disengage from the limit groove 69. Under the action of gravity, the collision block 10 or the impact pin 9 will fall, and then hit the lithium battery to be tested. If it is necessary to change the impact force during the collision, first insert the plug 53 into the slot 55 of the corresponding counterweight 54. The lower the position where the plug 53 is inserted, the more the counterweight 54, and the smaller the initial velocity of the collision block 10 or the impact pin 9 falling, the smaller the impact force. Then, start the electric push rod 62 to complete the test. When it is necessary to wind up the pull rope 51, start the electric push rod 62 to move the fixed disk 67 close to the wire winding column 64. When the semi-circular protrusions 65 on both sides are in contact with each other, the wire winding column 64 will rotate, so that the plug-in assembly 66 is inserted into the corresponding limit groove 69. Then, rotate the first motor 63 to wind up the pull rope 51 by the wire winding column 64 and pull the collision block 10 or the impact pin 9 back to the upper side.
