Description

Technical Field

[0001] The present invention belongs to the technical field of battery cover plates, and particularly relates to a sealing cover plate for a new energy aluminum shell battery. Background Art

[0002] A battery includes a cover plate, a housing, a battery cell, etc. Among them, the battery cell is placed inside the housing, the cover plate is sealed and installed at the upper opening of the housing. A liquid injection hole for injecting electrolyte into the interior of the housing and an explosion-proof valve for preventing the entire battery from exploding due to excessive temperature and pressure inside the battery are provided on the cover plate.

[0003] In the prior art, the first buffer groove provided can accommodate the electrolyte overflowing from the liquid injection hole, which can effectively prevent the electrolyte overflowing from the liquid injection hole from flowing to the explosion-proof valve installation hole and eroding the explosion-proof valve. And the first diversion groove provided can discharge the electrolyte in the first buffer groove from the side of the cover plate body, which can effectively prevent the electrolyte from overflowing from the first buffer groove, and can further prevent the electrolyte from flowing to the explosion-proof valve installation hole and eroding the explosion-proof valve, so as to effectively avoid damage to the explosion-proof valve and improve the yield of battery production. However, in the prior art, the liquid injection hole is located on the battery cover plate. During the process of injecting electrolyte into the battery through the liquid injection hole, the electrolyte is likely to drip onto the outer wall of the battery cover plate, resulting in the need for workers to clean the electrolyte dripping on the outer wall of the battery cover plate, increasing the labor intensity of the workers; moreover, the size of the liquid injection hole is small and cannot be enlarged, resulting in difficulty for the electrolyte to pass through the liquid injection hole and be transported into the battery. Summary of the Invention

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A sealing cover plate for a new energy aluminum shell battery includes a battery cover plate. A liquid injection pipe is communicated with the top of the battery cover plate. A liquid inlet pipe is arranged on the outer side of the liquid injection pipe. A rubber pipe is arranged at the top of the liquid inlet pipe. A sealing plate is arranged on the outer side of the rubber pipe. A liquid delivery pipe is communicated with the liquid inlet pipe. A corrugated pipe is arranged at the end of the liquid delivery pipe far away from the liquid inlet pipe, and the end of the corrugated pipe far away from the liquid delivery pipe is communicated with the liquid injection pipe. Electrode installation holes are opened on both sides of the battery cover plate. An explosion-proof valve installation hole is opened in the middle of the battery cover plate. An extension mechanism is arranged at the top of the battery cover plate, and a liquid inlet mechanism is arranged on the liquid inlet pipe.

[0006] Preferably, the extension mechanism includes a first disc handle arranged above the battery cover plate. A rotating shaft is fixedly connected to the bottom of the first disc handle. The rotating shaft is rotationally connected with the liquid injection pipe. A spur gear is fixedly connected to the outer side of the rotating shaft. A rack is meshed with the outer side of the spur gear. The rack is fixedly connected with a connecting ring through a connecting shaft, and the connecting ring is fixedly connected with the liquid delivery pipe.

[0007] Preferably, the extension mechanism further includes a sliding plate fixedly connected to the rack. A first guiding groove is formed in the top of the battery cover plate, and the sliding plate is slidably connected to the first guiding groove.

[0008] Preferably, the extension mechanism further includes an anti-shake member disposed outside the first disc handle. The anti-shake member includes a support plate fixedly connected to the top of the battery cover plate. A mounting seat is fixedly connected to the top of the support plate. A limiting plate is connected inside the mounting seat through a first spring. A communication groove is formed in one side of the mounting seat close to the limiting plate. A plug board is fixedly connected to the outside of the first disc handle, and the plug board is inserted into the limiting plate.

[0009] Preferably, the anti-shake member further includes a partition plate disposed between the limiting plate and the plug board. A U-shaped handle is fixedly connected to the outer wall of the partition plate. A second guiding groove is formed in the outer wall of the mounting seat, and the U-shaped handle is slidably connected to the second guiding groove.

[0010] Preferably, the liquid inlet mechanism includes a mounting plate slidably connected to the top of the liquid inlet pipe. A top rod is fixedly connected to the bottom of the mounting plate. A second disc handle is fixedly connected to the bottom of the top rod. A second spring is disposed outside the top rod. One end of the second spring is fixedly connected to the second disc handle, and the other end of the second spring is fixedly connected to the bottom of the liquid inlet pipe. The top of the mounting plate is fixedly connected to the sealing plate through a connecting column.

[0011] Preferably, the liquid inlet mechanism further includes a wedge-shaped block fixedly connected to the top of the mounting plate. A guiding seat is disposed above the liquid inlet pipe. A sliding block is fixedly connected to the guiding seat through a first connecting plate, and a flaring plate is fixedly connected to the guiding seat through a second connecting plate.

[0012] Preferably, the liquid inlet mechanism further includes a support seat fixedly connected to the top of the liquid inlet pipe. A third guiding groove is formed in the inner side of the support seat, and the guiding seat is slidably connected to the third guiding groove.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] Before injecting the electrolyte, the first disc handle of the present invention can be rotated. Since the bottom of the first disc handle is fixedly connected to a rotating shaft, and the rotating shaft is rotatably connected to the liquid injection pipe, the spur gear fixedly connected to the inner side of the rotating shaft can be driven to rotate, and then the rack arranged meshing on the outside is driven to move. Also, since the rack is fixedly connected to the connecting ring through the connecting shaft, the connecting ring is arranged on the infusion pipe, and the two ends of the infusion pipe are respectively communicated with the liquid inlet pipe and the corrugated pipe, the corrugated pipe is stretched and the liquid inlet pipe will move outside the battery cover under the drive of the connecting ring and the infusion pipe. Moreover, during the movement, the sliding plate fixedly connected to the bottom of the rack will slide in the first guiding groove opened on the top of the battery cover, and the first guiding groove has a limiting and guiding effect, thereby improving the stability of the liquid inlet pipe during movement. Before injecting the electrolyte, the present invention can move the liquid inlet pipe out of the top of the battery cover, avoiding the electrolyte dripping onto the battery cover when injecting the electrolyte. Additionally, when the electrolyte injection is not carried out, it can be contracted to the top of the battery cover, thus saving space.

[0015] After the liquid inlet pipe is moved out of the top of the battery cover in the present invention, the plug board fixedly connected to the outer wall of the first disc handle corresponds to the partition board. Subsequently, hold the U-shaped handle and pull it upward, so that the U-shaped handle slides in the second guiding groove and drives the partition board fixedly connected to the U-shaped handle to move to the upper end of the mounting seat. At this time, the communication groove opened on one side of the mounting seat is opened. Since the inside of the mounting seat is connected to a limiting plate through a first spring and the first spring is in a compressed state in the mounting seat, after the partition board is removed, the first spring resets and drives the limiting plate to move towards the plug board, and then the limiting plate is sleeved outside the plug board. The plug board is clamped by the limiting plates on both sides and the limiting plate is in the communication groove, making the first disc handle unable to rotate significantly. The present invention has a certain limiting effect on the movable first disc handle before injecting the electrolyte, avoiding accidentally touching the first disc handle when injecting the electrolyte, which may cause the liquid inlet pipe to shake significantly and result in the electrolyte dripping outside the liquid inlet pipe.

[0016] After the first disc handle is clamped by two limit plates in the present invention, the second disc handle can be pushed. Since the second disc handle is fixedly connected to the mounting plate through a push rod, the mounting plate is fixedly connected to the sealing plate through a connecting column, and both ends of the second spring are connected to the second disc handle and the liquid inlet pipe respectively, the second spring is compressed and can drive the push rod to move upward, thereby driving the mounting plate and the sealing plate to move upward, so that the nozzle of the liquid inlet pipe is opened. The present invention can quickly open the nozzle of the liquid inlet pipe, facilitating the delivery of the electrolyte into the liquid inlet pipe. During the process of the push rod driving the mounting plate to move upward in the present invention, since a wedge-shaped block is fixedly connected to the top of the mounting plate, the moving wedge-shaped block will squeeze the sliding block. After being squeezed, the sliding block will drive the guide seat to slide in the third guide groove opened inside the support seat through the first connecting plate. Also, since the guide seat is fixedly connected to the flaring plate through the second connecting plate, the flaring plate will push the rubber tube outward, causing the rubber tube at the top of the liquid inlet pipe to deform outward, thereby expanding the nozzle of the liquid inlet pipe. The present invention can expand the nozzle of the liquid inlet pipe while opening the liquid inlet pipe, facilitating the delivery of the electrolyte into the liquid inlet pipe.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0029] The following electrical components are all electrically connected to the peripheral PLC controller.

[0030] Refer to Figure 1 - Figure 7 , a sealing cover plate for a new energy aluminum shell battery, including a battery cover plate 1. A liquid injection pipe 2 is communicated with the top of the battery cover plate 1. A liquid inlet pipe 5 is arranged on the outer side of the liquid injection pipe 2. A rubber pipe 6 is arranged on the top of the liquid inlet pipe 5. A sealing plate 7 is arranged on the outer side of the rubber pipe 6. A liquid delivery pipe 4 is communicated with the liquid inlet pipe 5. One end of the liquid delivery pipe 4 away from the liquid inlet pipe 5 is provided with a corrugated pipe 3. One end of the corrugated pipe 3 away from the liquid delivery pipe 4 is communicated with the liquid injection pipe 2. Electrode mounting holes 10 are opened on both sides of the battery cover plate 1. An explosion-proof valve mounting hole 11 is opened in the middle of the battery cover plate 1. An extension mechanism 8 is arranged on the top of the battery cover plate 1. A liquid inlet mechanism 9 is arranged on the liquid inlet pipe 5.

[0031] Specifically, in the present invention, electrolyte is conveyed into the liquid inlet pipe 5, so that the electrolyte is conveyed to the liquid injection pipe 2 through the liquid delivery pipe 4 and the corrugated pipe 3, and finally the electrolyte is conveyed into the new energy aluminum shell battery through the liquid injection pipe 2.

[0032] In the embodiment, refer to Figures 1 - 3, in order to move the liquid inlet pipe 5 out of the top of the battery cover plate 1 before injecting the electrolyte and avoid the electrolyte dripping onto the battery cover plate 1 when injecting the electrolyte, the extension mechanism 8 includes a first disc handle 801 arranged above the battery cover plate 1. A rotating shaft 802 is fixedly connected to the bottom of the first disc handle 801. The rotating shaft 802 is rotatably connected to the liquid injection pipe 2. A spur gear 803 is fixedly connected to the outer side of the rotating shaft 802. A rack 804 is meshed and arranged on the outer side of the spur gear 803. The rack 804 is fixedly connected to a connecting ring 806 through a connecting shaft 805. The connecting ring 806 is fixedly connected to the infusion pipe 4. The extension mechanism 8 further includes a sliding plate 807 fixedly connected to the rack 804. A first guiding groove 808 is formed in the top of the battery cover plate 1. The sliding plate 807 is slidably connected to the first guiding groove 808.

[0033] Specifically, before injecting the electrolyte, the first disc handle 801 can be rotated in the present invention. Since the rotating shaft 802 is fixedly connected to the bottom of the first disc handle 801 and the rotating shaft 802 is rotatably connected to the liquid injection pipe 2, the spur gear 803 fixedly connected to the inner side of the rotating shaft 802 can be driven to rotate, and then the rack 804 meshed on the outer side can be driven to move. Also, since the rack 804 is fixedly connected to the connecting ring 806 through the connecting shaft 805, the connecting ring 806 is arranged on the infusion pipe 4, and both ends of the infusion pipe 4 are respectively communicated with the liquid inlet pipe 5 and the corrugated pipe 3, the corrugated pipe 3 is stretched and the liquid inlet pipe 5 will move outside the battery cover plate 1 under the drive of the connecting ring 806 and the infusion pipe 4. Moreover, during the moving process, the sliding plate 807 fixedly connected to the bottom of the rack 804 will slide in the first guiding groove 808 formed in the top of the battery cover plate 1. The first guiding groove 808 has a limiting and guiding effect, thereby improving the stability of the liquid inlet pipe 5 during movement. Before injecting the electrolyte, the liquid inlet pipe 5 can be moved out of the top of the battery cover plate 1 in the present invention to avoid the electrolyte dripping onto the battery cover plate 1 when injecting the electrolyte. In addition, when the electrolyte is not injected, it can be retracted to the top of the battery cover plate 1, thus saving space.

[0034] In the embodiment, refer to Figures 4 - 5, in order to have a certain limiting effect on the first disc handle 801 before injecting the electrolyte, and to prevent accidentally touching the first disc handle 801 during the electrolyte injection, which may cause the liquid inlet pipe 5 to shake greatly and result in the electrolyte dripping outside the liquid inlet pipe 5, the extension mechanism 8 further includes an anti-shake member 809 disposed outside the first disc handle 801. The anti-shake member 809 includes a support plate 8091 fixedly connected to the top of the battery cover plate 1. A mounting seat 8092 is fixedly connected to the top of the support plate 8091. A limiting plate 8094 is connected inside the mounting seat 8092 through a first spring 8093. A communication groove 8095 is formed on one side of the mounting seat 8092 close to the limiting plate 8094. A plug plate 8096 is fixedly connected to the outside of the first disc handle 801, and the plug plate 8096 is inserted into the limiting plate 8094. The anti-shake member 809 further includes a partition plate 8097 disposed between the limiting plate 8094 and the plug plate 8096. A U-shaped handle 8098 is fixedly connected to the outer wall of the partition plate 8097. A second guiding groove 8099 is formed on the outer wall of the mounting seat 8092, and the U-shaped handle 8098 is slidably connected to the second guiding groove 8099.

[0035] Specifically, in the present invention, after the liquid inlet pipe 5 is removed from the top of the battery cover plate 1, the plug plate 8096 fixedly connected to the outer wall of the first disc handle 801 corresponds to the partition plate 8097. Then, hold the U-shaped handle 8098 and pull it upward, so that the U-shaped handle 8098 slides in the second guiding groove 8099 and drives the partition plate 8097 fixedly connected to the U-shaped handle 8098 to move to the upper end of the mounting seat 8092. At this time, the communication groove 8095 formed on one side of the mounting seat 8092 is opened. Since the limiting plate 8094 is connected inside the mounting seat 8092 through the first spring 8093 and the first spring 8093 is in a compressed state inside the mounting seat 8092, after the partition plate 8097 is removed, the first spring 8093 resets and drives the limiting plate 8094 to move towards the plug plate 8096, and then the limiting plate 8094 is sleeved outside the plug plate 8096. The plug plate 8096 is clamped by the limiting plates 8094 on both sides and the limiting plate 8094 is located in the communication groove 8095, so that the first disc handle 801 cannot rotate greatly. The present invention has a certain limiting effect on the movable first disc handle 801 before injecting the electrolyte, and prevents accidentally touching the first disc handle 801 during the electrolyte injection, which may cause the liquid inlet pipe 5 to shake greatly and result in the electrolyte dripping outside the liquid inlet pipe 5.

[0036] In the embodiment, refer to Figure 6, in order to quickly open the nozzle of the liquid inlet pipe 5 and facilitate the delivery of the electrolyte into the liquid inlet pipe 5, the liquid inlet mechanism 9 includes a mounting plate 901 slidably connected to the top of the liquid inlet pipe 5. A push rod 902 is fixedly connected to the bottom of the mounting plate 901. A second disc handle 904 is fixedly connected to the bottom of the push rod 902. A second spring 903 is arranged outside the push rod 902. One end of the second spring 903 is fixedly connected to the second disc handle 904, and the other end of the second spring 903 is fixedly connected to the bottom of the liquid inlet pipe 5. The top of the mounting plate 901 is fixedly connected to the sealing plate 7 through a connecting column 905.

[0037] Specifically, after the present invention clamps the first disc handle 801 with two limit plates 8094, the second disc handle 904 can be pushed. Since the second disc handle 904 is fixedly connected to the mounting plate 901 through the push rod 902, the mounting plate 901 is fixedly connected to the sealing plate 7 through the connecting column 905, and both ends of the second spring 903 are connected to the second disc handle 904 and the liquid inlet pipe 5 respectively, the second spring 903 is compressed and can drive the push rod 902 to move upward, thereby driving the mounting plate 901 and the sealing plate 7 to move upward, so that the nozzle of the liquid inlet pipe 5 is opened. The present invention can quickly open the nozzle of the liquid inlet pipe 5, facilitating the delivery of the electrolyte into the liquid inlet pipe 5.

[0038] In the embodiment, referring to Figure 7 , in order to expand the nozzle of the liquid inlet pipe 5 and facilitate the delivery of the electrolyte into the liquid inlet pipe 5, the liquid inlet mechanism 9 further includes a wedge-shaped block 906 fixedly connected to the top of the mounting plate 901. A guide seat 909 is arranged above the liquid inlet pipe 5. The guide seat 909 is fixedly connected with a sliding block 907 through a first connecting plate 908, and the guide seat 909 is fixedly connected with a flaring plate 911 through a second connecting plate 910. The liquid inlet mechanism 9 further includes a support seat 912 fixedly connected to the top of the liquid inlet pipe 5. A third guide groove 913 is opened inside the support seat 912, and the guide seat 909 is slidably connected with the third guide groove 913.

[0039] Specifically, during the process of the push rod 902 driving the mounting plate 901 to move upward, since the wedge-shaped block 906 is fixedly connected to the top of the mounting plate 901, the moving wedge-shaped block 906 will squeeze the sliding block 907. After being squeezed, the sliding block 907 will drive the guide seat 909 to slide in the third guide groove 913 opened inside the support seat 912 through the first connecting plate 908. And since the guide seat 909 is fixedly connected with the flaring plate 911 through the second connecting plate 910, the flaring plate 911 will push the rubber tube 6 outward, causing the rubber tube 6 at the top of the liquid inlet pipe 5 to deform outward, thereby expanding the nozzle of the liquid inlet pipe 5. The present invention can expand the nozzle of the liquid inlet pipe 5 while opening the liquid inlet pipe 5, facilitating the delivery of the electrolyte into the liquid inlet pipe 5.

[0040] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
