Description

Technical Field

[0001] This invention belongs to the field of battery cover detection, specifically a power battery cover detection device and its usage method. Background Technology

[0002] A power battery is a power source that provides power to tools. It often refers to the storage battery that powers electric vehicles, electric trains, electric bicycles, and golf carts. When assembling a power battery, a cover is installed on top of it to protect the top of the power battery and enhance its safety.

[0003] To effectively understand the safety of power battery cover plates, inspectors will place the power battery cover plate components on a pressure testing instrument for testing. Currently, most pressure testing instruments have an open front end. If workpiece residue is generated during the test due to compression, the splashed residue may pose a certain degree of harm to the safety of the surrounding inspectors. Therefore, it is necessary to improve the existing equipment based on its shortcomings.

[0004] In summary, the present invention provides a power battery cover detection device and its usage method to solve the above problems. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a power battery cover testing device and its usage method. This addresses the issue that in the prior art, to effectively assess the safety of power battery covers, inspectors place the cover components on a pressure testing instrument. Currently, most pressure testing instruments have an open front end. If workpiece residue is ejected during the test due to compression, this ejected residue poses a safety hazard to surrounding inspectors. Therefore, improvements are needed to address the shortcomings of existing equipment.

[0006] A power battery cover detection device and its usage method include a controller, one end of which is linearly connected to a pressure detector, a base is installed inside the pressure detector, and a platform is installed on the surface of the base.

[0007] An installation strip is mounted on the upper surface of the controller. A lead screw is threaded through both sides of the installation strip. One end of the lead screw is connected to a clamping mechanism, and one end of the clamping mechanism is connected to a protective plate.

[0008] Preferably, the clamping mechanism includes a transmission head, a bearing, a connecting column, and a clamp. One end of the transmission head is fixedly connected to a lead screw, the other end of the transmission head is connected to the inner ring of the bearing, the outer ring on the other side of the bearing is fixedly connected to the connecting column, and the other end of the connecting column is fixedly connected to a clamp.

[0009] Preferably, the clamp has a top view structure that is an inverted "U" shape, the recessed area of ​​the clamp is clamped and connected to the outer wall of the protective plate, and the clamp is made of hard rubber.

[0010] Preferably, the protective plate extends through the upper and lower sides of the mounting strip, the protective plate is made of tempered glass, and the lateral length of the top of the protective plate is greater than the opening length of the mounting strip.

[0011] Preferably, two start buttons are installed on the outer wall at the bottom of the pressure detector. The start buttons are covered by an outer cover. A partition is installed on the surface opening of the outer cover. A docking mechanism is installed at the bottom of the outer cover. The docking mechanism is installed inside the mounting groove.

[0012] Preferably, the docking mechanism includes a plug and a fitting strip, one end of the plug is fixedly connected to the bottom of the outer cover, and the fitting strip is inserted into one side of the plug.

[0013] Preferably, the other end of the fitting strip is fixedly connected to the inner wall of the mounting groove, which is opened on the surface of the pressure detector, and the size of the mounting groove is larger than the size of the insert block.

[0014] Preferably, a docking post is fixedly installed on the top of the base, the docking post is inserted into the docking groove, the docking groove is opened at the bottom of the platform, a spring is installed in the recessed groove on the inner wall of the docking groove, and one end of the spring is connected to the closing mechanism.

[0015] Preferably, the closing mechanism includes a sliding plate, a flexible joint, and a magnetic strip. The bottom of the sliding plate is fixedly connected to the top of the spring, and the top of the sliding plate is fixedly connected to the flexible joint. A magnetic strip is installed on the end of the flexible joint. Two inclined sliding plates are symmetrically installed inside the mating groove, and the dimensions of the two sliding plates extending out of the recessed groove end match the internal dimensions of the mating groove.

[0016] A method for using a power battery cover detection device includes the following steps:

[0017] The first step is to set the required pressure value for the test on the controller, and then place the power battery cover plate component on the platform;

[0018] The second step is to place the power battery cover component. At this time, adjust the protective plate downward so that the protective plate covers the opening of the pressure detector.

[0019] Third, after the protective plate is adjusted, press the two start buttons. In this way, the pressure detector's pressing mechanism will apply pressure to the surface of the power battery cover component at the set pressure.

[0020] The fourth step involves the pressure detector continuously applying pressure until the power battery cover is eventually crushed. At the same time as the battery is crushed, the controller records the pressure value during the crushing process, thus enabling the detection of the pressure resistance index of the power battery cover.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. This invention loosens the lead screw, thus loosening the connection between the clamp and the protective plate. At this time, the protective plate is moved downward, and finally the protective plate will block the opening end of the pressure detector. When in use, the inside of the pressure detector will be separated from the outside. Therefore, even if the workpiece inside is squeezed and splashed during use, it will not splash to the outside of the pressure detector, thus ensuring the safety of personnel around the pressure detector.

[0023] 2. By installing an outer cover outside the start button, the three strips on the outer cover will cover the front of the start button. When using it, the operator must accurately insert their fingers through the gaps between the strips to operate the start button. In this way, the operator's operation is improved through this structure.

[0024] 3. After the stage and base are separated, the spring will drive the sliding plate to reset. After the sliding plate is reset, it will seal the bottom of the docking groove. Thus, during use, the opening of the docking groove at the bottom of the stage can be sealed to prevent foreign objects from entering the docking groove and affecting the connection between the docking column and the docking groove in the next operation.

[0035] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0036] like Figure 1 , 4 As shown in Figures 5 and 6, the present invention provides a power battery cover detection device and its usage method, including a controller 1, one end of the controller 1 is linearly connected to a pressure detector 2, a base 3 is installed inside the pressure detector 2, and a platform 4 is installed on the surface of the base 3.

[0037] An mounting strip 5 is installed on the upper surface of the controller 1. A lead screw 6 is threaded through both sides of the mounting strip 5. One end of the lead screw 6 is connected to the clamping mechanism, and one end of the clamping mechanism is connected to the protective plate 11.

[0038] Please refer to Figure 5 The clamping mechanism includes a transmission head 7, a bearing 8, a connecting column 9, and a clamp 10. One end of the transmission head 7 is fixedly connected to the lead screw 6, and the other end of the transmission head 7 is connected to the inner ring of the bearing 8. The outer ring on the other side of the bearing 8 is fixedly connected to the connecting column 9. The clamp 10 is fixedly connected to the other end of the connecting column 9. When the lead screw 6 is released, it will drive the transmission head 7 to move outward. When the transmission head 7 moves, it will drive the bearing 8 to move outward. When the bearing 8 moves, it will drive the connecting column 9 to move. When the connecting column 9 moves, it will drive the clamp 10 to move to one side. In this way, the connection between the clamp 10 and the protective plate 11 will be loosened.

[0039] Please refer to Figure 6 The top view of the clamp 10 is an inverted "U" shaped structure. The recessed area of ​​the clamp 10 clamps and connects with the outer wall of the protective plate 11. The clamp 10 is made of hard rubber, so that when the clamp 10 clamps the protective plate 11, the clamp 10 can reduce the damage to the protective plate 11.

[0040] Please refer to Figure 1The protective plate 11 extends through the upper and lower sides of the mounting strip 5. The protective plate 11 is made of tempered glass. The horizontal length of the top of the protective plate 11 is greater than the opening length of the mounting strip 5. The protective plate 11 covers the opening end of the pressure detector 2. When in use, the inside of the pressure detector 2 will be separated from the outside. Thus, even if the workpiece inside is squeezed and splashed during use, it will not splash to the outside of the pressure detector 2.

[0041] Please refer to Figure 1 , 7 8 and 9, two start buttons 23 are installed on the outer wall of the bottom of the pressure detector 2. The start buttons 23 are covered by an outer cover 12. A spacer 13 is installed on the opening of the surface of the outer cover 12. A docking mechanism is installed at the bottom of the outer cover 12. The docking mechanism is installed inside the mounting groove 16 to connect the insert block 14 at the bottom of the outer cover 12 to the mounting groove 16. In this way, the outer cover 12 can be installed outside the start button 23.

[0042] Please refer to Figure 9 The docking mechanism includes a plug 14 and a fitting strip 15. One end of the plug 14 is fixedly connected to the bottom of the outer cover 12, and the fitting strip 15 is inserted into the inside of one side of the plug 14.

[0043] Please refer to Figure 9 The other end of the fitting strip 15 is fixedly connected to the inner wall of the mounting groove 16. The mounting groove 16 is opened on the surface of the pressure detector 2. The size of the mounting groove 16 is larger than the size of the insert 14. After the insert 14 enters the mounting groove 16, the outer cover 12 is pulled down, so that the insert 14 will move down. When the insert 14 moves to the bottom of the mounting groove 16, it will be inserted into the fitting strip 15, so that the insert 14 is installed on the outer wall of the pressure detector 2.

[0044] Please refer to Figure 2 and 3 A docking post 17 is fixedly installed on the top of the base 3. The docking post 17 is inserted into the docking groove 18. The docking groove 18 is opened at the bottom of the platform 4. A spring 19 is installed in the recessed groove on the inner wall of the docking groove 18. One end of the spring 19 is connected to the closing mechanism.

[0045] Please refer to Figure 3The closing mechanism includes a sliding piece 20, a flexible joint 21, and a magnetic strip 22. The bottom of the sliding piece 20 is fixedly connected to the top of the spring 19, and the top of the sliding piece 20 is fixedly connected to the flexible joint 21. A magnetic strip 22 is installed on the end of the flexible joint 21. Two inclined sliding pieces 20 are symmetrically installed inside the mating groove 18. The size of the two sliding pieces 20 extending out of the recessed groove matches the internal size of the mating groove 18. When the spring 19 resets, it will drive the sliding piece 20 to reset. When the sliding piece 20 resets, it will drive the flexible joint 21 to reset. When the flexible joint 21 resets, it will drive the magnetic strip 22 to reset. Finally, the two magnetic strips 22 will attract each other together.

[0046] A method for using a power battery cover detection device includes the following steps:

[0047] First, set the required pressure value for the test on controller 1, and then place the power battery cover plate component on the stage 4;

[0048] The second step is to place the power battery cover component. At this time, adjust the protective plate 11 downward so that the protective plate 11 covers the opening of the pressure detector 2.

[0049] Third, after the protective plate 11 is adjusted, press the two start buttons 23. In this way, the pressure detector 2 will apply pressure to the surface of the power battery cover component at the set pressure.

[0050] Fourth, as the pressure detector 2 continues to apply pressure, the power battery cover component will eventually be crushed. At the same time as the component is crushed, the controller 1 will record the pressure value during the crushing process, thus detecting the pressure resistance index of the power battery cover component.

[0051] Specific working principle: such as Figure 1-9 As shown, when using this power battery cover detection device and its usage method, firstly, loosen the lead screw 6. When the lead screw 6 is loosened, it will drive the transmission head 7 to move outward. When the transmission head 7 moves, it will drive the bearing 8 to move outward. When the bearing 8 moves, it will drive the connecting column 9 to move. When the connecting column 9 moves, it will drive the clamp 10 to move to one side. In this way, the connection between the clamp 10 and the protective plate 11 will be loosened. At this time, the protective plate 11 is moved downward. Finally, the protective plate 11 will block the opening end of the pressure detector 2. When in use, the inside of the pressure detector 2 will be separated from the outside. Thus, even if the workpiece inside is squeezed and splashed, it will not splash to the outside of the pressure detector 2, so as to ensure the safety of personnel around the pressure detector 2.

[0052] Next, connect the insert 14 at the bottom of the outer cover 12 to the mounting groove 16. After the insert 14 enters the mounting groove 16, pull the outer cover 12 down. The insert 14 will move downward. When the insert 14 moves to the bottom of the mounting groove 16, it will be inserted into the fitting strip 15, so that the insert 14 is installed on the outer wall of the pressure detector 2. In this way, the outer cover 12 can be installed outside the start button 23. The three spacers 13 on the outer cover 12 will cover the front of the start button 23. When using it, the operator must accurately pass his finger through the gap between the spacers 13 to operate the start button 23. In this way, the operator's operating procedures can be improved through this structure.

[0053] Finally, after the platform 4 and the base 3 separate, the spring 19 will reset. When the spring 19 resets, it will drive the sliding piece 20 to reset. When the sliding piece 20 resets, it will drive the flexible joint 21 to reset. When the flexible joint 21 resets, it will drive the magnetic strip 22 to reset. Finally, the two magnetic strips 22 will attract each other together. Thus, during use, this structure can be used to seal the opening of the docking groove 18 at the bottom of the platform 4 to prevent foreign objects from entering the docking groove 18 and affecting the connection between the docking column 17 and the docking groove 18 in the next operation. This is the feature of the power battery cover detection device and its usage method.
