Description

Technical Field

[0002] New energy generally refers to renewable energy that is developed and utilized based on new technologies, including solar energy, biomass energy, wind energy, geothermal energy, wave energy, ocean current energy and tidal energy, as well as thermal cycles between the ocean surface and deep layers; in addition, there are hydrogen energy, biogas, alcohol, methanol, etc., while the widely used energy such as coal, oil, natural gas, and hydropower are called conventional energy. With the limitation of conventional energy and the increasing prominence of environmental problems, new energy with environmental protection and renewable characteristics has been increasingly valued by various countries.

[0003] The battery cell refers to the small battery in the power battery of new energy vehicles. The power battery pack is generally composed of 12 battery cells assembled into one module, and then combined with 16 modules. The battery cell is mainly composed of positive electrode materials, negative electrode materials, electrolytes and diaphragms. According to the different positive electrode materials, it can be divided into lithium iron phosphate batteries and ternary lithium batteries. The battery cell is generally not equipped with a protective shell, but a simple structure. Its main function is to assemble the battery pack; the battery is generally equipped with a shell and a protection circuit, and the battery pack can be used directly. From a structural point of view, the battery cell is only a part of the battery. The structure of the power battery is generally divided into battery cells, protection boards, connection boards and control boards. The protection board plays the role of protecting the battery cell; the connection board connects the battery and the control board; as for the control board, it is a circuit board that gives the battery various protection functions.

[0004] With the rise of new energy and environmental protection, in the lithium battery production process, it is necessary to fill the battery cells into the lithium battery shell. However, when the existing clamps clamp the lithium battery shell, because the material of the clamps is mostly metal and the clamps are clamped by mechanical transmission, the transmission force is large, which will damage the lithium battery shell. After the battery cells are filled, the lithium battery with a damaged shell does not meet the production standards, wasting production resources.

The new energy vehicle battery anti-collision detection device, through the first motor, bidirectional screw rod, limit piece and slide rod, conveniently drives the two screw sleeves to slide towards each other, and the positioning rod and positioning plate on each screw sleeve move back and forth with the screw sleeve, which is convenient for limiting the position of automobile batteries of different sizes. However, a complex clamping mechanism is designed to limit the battery only by clamping, and excessive clamping force may cause damage to the battery surface, affecting the quality of the tested battery.

[0030] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar symbols throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0031] like Figure 1-3 As shown, the utility model discloses a new energy vehicle battery anti-collision detection device, including a base 200, a detection box 100 is connected to the top of the base 200, the detection box 100 is roughly rectangular, and an anti-collision detection working area is formed inside the detection box 100, and the anti-collision detection working area is provided with:

[0032] The workbench assembly 300, such as Figure 1As shown, the workbench assembly 300 includes an adsorption table 310 and a workbench box seat 320. The bottom of the workbench box seat 320 is connected to the base 200. A negative pressure pump 330 can be arranged in the workbench box seat 320. The top surface of the workbench box seat 320 is connected to the adsorption table 310. An air inlet is opened on the surface of the adsorption table 310. The air suction port of the negative pressure pump 330 is connected to the air inlet on the surface of the adsorption table 310. The negative pressure pump 330 sucks air to form a negative pressure on the surface of the adsorption table 310, so that the battery can be adsorbed and fixed when placed on the adsorption table 310.

[0033] Furthermore, a placement plate 340 is provided on the top surface of the adsorption platform 310. The placement plate 340 is provided with ventilation holes. The battery is placed on the placement plate 340, and the negative pressure gas adsorbs the battery through the placement plate 340. The placement plate 340 is convenient for taking and placing the battery, and is also convenient for the operation of the negative pressure pump 330.

[0034] Positioning reinforcement assembly 400, such as Figure 2 As shown, the positioning reinforcement assembly 400 may include two sets of slide rails 410, which are arranged opposite to each other and connected to the two opposite sides of the inner wall of the detection box 100, and each set of slide rails 410 is slidably connected to a clamping plate 420, and the connection between the clamping plate 420 and the slide rail 410 can be adopted as follows Figure 2 As shown, the clamping plate 420 is connected to the slider 421, the slider 421 is slidably connected to the slide rail 410, the bottom of the slider 421 is connected to the telescopic end of the hydraulic telescopic rod 430, the base 200 of the hydraulic telescopic rod 430 is connected to the inner wall of the detection box 100, and the clamping plate 420 can be driven to move along the slide rail 410 by the extension and retraction of the hydraulic telescopic rod 430.

[0035] The opposite ends of the two clamping plates 420 are connected to push plates 440. When in use, the battery is placed on the placement plate 340, and the push plate 440 is pushed by the clamping plate 420 to clamp and fix the battery from both sides, so that the battery is firmly fixed on the placement plate 340, ensuring the smooth progress of the impact detection.

[0036] Furthermore, the two push plates 440 are connected to opposite sides with heat-insulating rubber pads 440a, and the surface of the heat-insulating rubber pads 440a is uneven. The uneven heat-insulating rubber pads 440a can be used to increase the friction between the push plates 440 and the battery, thereby improving the stability of the push plates 440 clamping.

[0037] Impact test assembly 500, such as Figure 1 , 3As shown, the impact test assembly 500 is arranged above the workbench assembly 300, and the impact test assembly 500 includes a straight cylinder 520, which is connected to the top of the detection box 100 and passes through the detection box 100. The straight cylinder 520 is internally sleeved with a driving rod 530, and the driving rod 530 can slide up and down along the straight cylinder 520. The top of the driving rod 530 is connected to a release device 540, and the bottom of the driving rod 530 is connected to a counterweight test block 510.

[0038] When performing a battery anti-collision test, the release device 540 is used to control the driving rod 530 to fall, so that the driving rod 530 falls along the straight cylinder 520, and the counterweight test block 510 connected to the bottom of the driving rod 530 hits the battery to perform a battery anti-collision test experiment.

[0039] Furthermore, the structure of the release device 540 is as follows: Figure 1 As shown, the release device 540 includes a half gear 541 and a servo motor 542. The servo motor 542 drives the half gear 541 to rotate. The gear teeth of the half gear 541 engage with the rack 550 at the top of the driving rod 530. The drive of the servo motor 542 can make the half gear 541 drive the rack 550 to move upward. Under the continuous rotation of the half gear 541, the gear teeth are separated from the rack 550, so that the driving rod 530 can perform free fall motion, so that the driving rod 530 and the counterweight test block 510 connected to it hit the upper surface of the battery to perform an anti-collision test of the battery.

[0040] After the driving rod 530 further falls, the position of the rack 550 returns to the range of meshing with the half gear 541. As the half gear 541 rotates, the half gear 541 and the rack 550 re-engage to achieve the next round of testing. During this test process, the servo motor 542 only needs to set the speed, and no excessive manual operation is required, which protects the safety of the inspectors.

[0041] Further, such as Figure 3 As shown, a test block 560 is connected between the bottom of the driving rod 530 and the counterweight test block 510. A groove 560a is provided at the bottom of the test block 560. The counterweight test block 510 is movably connected to the groove 560a. Through the counterweight test block 510 being movably connected to the groove 560a, different counterweight test blocks 510 can be replaced according to test needs, thereby facilitating the use of the test device.

[0042] According to the principle of the utility model, when in use, first place the battery on the upper surface of the placement plate 340, open the hydraulic telescopic rod 430, and use the hydraulic telescopic rod 430 to push the push plate 440 towards the battery. The push plates 440 on both sides limit and clamp the battery, and use the uneven heat-insulating rubber pad 440a to increase the friction with the battery and thus improve the stability of the clamping.

[0043] Since the negative pressure pump 330 is provided, when the battery is positioned and clamped, the negative pressure pump 330, the adsorption platform 310 with holes and the placement plate 340 can be used to adsorb the negative pressure of the battery on the upper surface of the placement plate 340. The multiple fixing methods not only improve the stability of the battery, but also will not cause damage to the battery casing.

[0044] Through the mutual engagement of the rack 550 and the half gear 541, the half gear 541 can be rotated and driven by the servo motor 542 to move the rack 550 upward. Under the rotation of the half gear 541, the half gear 541 is separated from the rack 550, so that the driving rod 530 can perform free fall motion, and further the counterweight test block 510 can impact the upper surface of the battery to perform a battery impact test.

[0045] After the driving rod 530 falls, the position of the rack 550 returns to the range of meshing with the half gear 541. As the half gear 541 rotates, the half gear 541 and the rack 550 re-engage to achieve the next round of testing. During this test process, the servo motor 542 only needs to set the speed, and no excessive manual operation is required, which protects the safety of the inspectors.
