Description

Technical Field

[0001] This invention relates to the field of battery technology, specifically to a new energy battery pack. Background Technology

[0002] With the development of science and technology, the development of new energy has made great progress, and the application of new energy batteries is becoming more and more widespread. New energy is a new type of energy that can replace traditional energy. It usually has the advantages of being renewable and having low pollution. The replacement of traditional energy by new energy is of great significance.

[0003] A search revealed a new energy lithium battery pack with authorization announcement number CN112436221B. This battery pack can reduce the temperature of the battery, which helps to reduce the possibility of shortening the life of the lithium battery.

[0004] However, the existing battery packs mentioned above cannot automatically detect battery pack bulges, and they cannot detect local battery bulges. Prolonged use can easily lead to spontaneous combustion, posing a significant safety hazard. Therefore, we propose a new energy battery pack. Summary of the Invention

[0005] This invention proposes a new energy battery pack that solves the problems of existing battery packs in related technologies, such as the inability to automatically detect battery packs, the inability to detect local battery bulging, and the risk of spontaneous combustion after prolonged use, posing significant safety hazards.

[0006] The technical solution of the present invention is as follows:

[0007] A new energy battery pack includes a shell and a top cover. The shell contains several groups of individual batteries, and a detection structure is provided between the groups of individual batteries. The shell has through holes at both ends, and a protective structure is provided on the inner wall of the shell near both ends.

[0008] The detection structure includes a hollow column fixedly connected to the outer surface of the housing. A threaded rod is provided on one side of the hollow column, and a guide rod is provided on one side of the threaded rod. A movable kit is movably sleeved on the outer surface of the threaded rod. A fixed plate is fixedly connected to the outer surface of the movable kit, and a detection ring is fixedly connected to the outer surface of the fixed plate.

[0009] The outer surface of the detection ring is fixedly connected to a protrusion, and the outer surface of the protrusion is provided with a through hole. The lower end of the threaded rod is connected to a drive motor.

[0010] As a further technical solution of the present invention, the detection ring includes a rigid inner ring fixedly connected to the outer surface of the fixed plate, an elastic sleeve fixedly connected to the outer surface of the rigid inner ring, a push post and a push spring provided between the elastic sleeve and the rigid inner ring, and the cavity formed between the elastic sleeve and the rigid inner ring is filled with gas.

[0011] As a further technical solution of the present invention, the protective structure includes a movable plate slidably connected to the outer surface of the inner wall at both ends of the housing. The outer surface of the movable plate is provided with a connecting hole. A protruding plate is fixedly connected to the outer surface of the movable plate. A movable spring is connected between the protruding plate and the inner wall of the housing. Limiting plates are fixedly connected to the upper and lower edges of the inner wall of the housing corresponding to the movable plate. An end guide plate is fixedly connected to the lower inner wall of the housing near the through hole. Side guide plates are fixedly connected to the inner wall of the housing near the sides.

[0012] As a further technical solution of the present invention, a set of threaded rods corresponds to several sets of hollow columns and detection rings, and the number of hollow columns and detection rings is a multiple of three. The hollow columns are arranged in an array around the axis of the threaded rod. The movable kit is threadedly connected to the threaded rod. The diameter of the through hole is equal to the diameter of the guide rod. The detection ring is movably sleeved on the outer surface of a single battery.

[0013] As a further technical solution of the present invention, the lower end of the single battery matches the interior of the hollow column, the number of detection rings is equal to that of the hollow column, and the positions of the detection rings and the hollow column correspond one-to-one. The number of guide rods is three sets, which are arranged in a ring array around the axis of the threaded rod. The protrusion is only provided outside the detection ring closest to the guide rod in a counterclockwise direction, and the two adjacent sets of detection rings are in a tangential line contact state.

[0014] As a further technical solution of the present invention, the inner diameter of the jacking spring is larger than that of the jacking column, the number of jacking columns and jacking springs are several groups, and the axis of the jacking column coincides with the axis of the jacking spring. The several groups of jacking columns are distributed in a ring array, the gas is carbon dioxide, and the elastic sleeve is an elastic rubber material.

[0015] As a further technical solution of the present invention, the movable spring is a spring that expands in summer and contracts in winter. The expansion and contraction of the movable spring causes the movable plate to move, thereby making the connecting opening between the connecting hole and the through hole larger or smaller until it is closed. The movement of the movable plate is guided by the limiting plate. The movable plate slides along the length direction of the limiting plate. There are three sets of protruding plates, and the spacing between adjacent sets of protruding plates is equal. There are three sets of through holes at one end of the outer shell. The number of movable plates is equal to the number of through holes.

[0016] As a further technical solution of the present invention, the end of the drive motor is provided with a motor stroke monitoring system, which is used to monitor the stroke of the protrusion. The drive motor and the motor stroke monitoring system are connected by a signal, and the end signal of the motor stroke monitoring system is connected to a mobile phone, a computer and a vehicle system.

[0017] As a further technical solution of the present invention, the opening size of one set of connecting holes is equal to the opening size of one set of through holes. There are two sets of end guide plates, which are arranged in an inverted "eight" shape. The side with the larger opening of the two sets of end guide plates is close to the connecting hole at the end of the connecting hole. There are two sets of side guide plates, which are arranged in an array. Several sets of side guide plates are arranged in a symmetrical oblique distribution structure, and the side with the larger opening faces the same direction as the side with the larger opening of the end guide plate. Only two sets of end guide plates are arranged inside the shell near one end.

[0018] As a further technical solution of the present invention, a positioning plate is movably arranged inside the outer shell. A protrusion is fixedly connected to the lower outer surface of the positioning plate, and a locking block is fixedly connected to the outer surface of the inner wall of the outer shell. A groove matching the protrusion is opened at the upper end of the locking block. The positioning plate matches the inner opening of the outer shell. A limiting opening is opened on the inner side of the positioning plate. The limiting opening matches several groups of individual batteries. The upper end of the individual battery is limited by the positioning plate. A closing plate is connected to the upper end of the positioning plate. A locking protrusion is fixedly connected to the lower end of the top cover. A locking groove matching the locking protrusion is opened on the outer surface of the outer shell.

[0019] The working principle and beneficial effects of this invention are as follows:

[0020] 1. In this invention, through the combined action of the detection structure and the motor stroke monitoring system, the outer surface of a single battery can be automatically detected during use. When bulging occurs, the travel of the drive motor can be used to determine whether a single battery has bulged. This allows for timely replacement of the bulging battery, thereby avoiding potential dangers caused by battery bulging.

[0021] 2. In this invention, the protective structure can maintain ventilation of the individual battery inside the casing in hot weather conditions such as summer, thereby reducing the heat generated by the battery. At the same time, it can maintain the heat preservation of the individual battery inside the casing in cold winter conditions, making the individual battery perform better and reducing the loss of the individual battery due to overheating or overcooling, thus avoiding the occurrence of shortened life of the individual battery.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1

[0036] like Figure 1 and Figure 7As shown, this embodiment proposes a new energy battery pack, including a shell 1 and a top cover 2. Several groups of individual batteries 3 are arranged inside the shell 1, and a detection structure 4 is arranged between the groups of individual batteries 3. Through holes 6 are opened at both ends of the shell 1, and a protective structure 5 is arranged on the inner wall of the shell 1 near both ends. A positioning plate 7 is movably arranged inside the shell 1. A protrusion 8 is fixedly connected to the lower outer surface of the positioning plate 7.

A closing plate 12 is connected to the upper end of the positioning plate 7. A locking protrusion 10 is fixedly connected to the lower end of the top cover 2. A locking groove 11 matching the locking protrusion 10 is opened on the outer surface of the shell 1.

[0037] Example 2

[0038] like Figure 1 and Figure 7As shown, based on Embodiment 1, a detection structure 4 is further proposed, including a hollow column 41 fixedly connected to the outer surface of the outer shell 1. A threaded rod 42 is provided on one side of the hollow column 41, and a guide rod 43 is provided on one side of the threaded rod 42. A movable sleeve 44 is movably sleeved on the outer surface of the threaded rod 42. A fixing plate 45 is fixedly connected to the outer surface of the movable sleeve 44, and a detection ring 46 is fixedly connected to the outer surface of the fixing plate 45. A protrusion 47 is fixedly connected to the outer surface of the detection ring 46, and a through hole 48 is opened on the outer surface of the protrusion 47. A drive motor 49 is connected to the lower end of the threaded rod 42. The detection ring 46 has a protrusion 47 fixedly connected to its outer surface, and a through hole 48 is opened on its outer surface. 6 includes a rigid inner ring 461 fixedly connected to the outer surface of the fixed plate 45. An elastic sleeve 462 is fixedly connected to the outer surface of the rigid inner ring 461. A pusher post 463 and a pusher spring 464 are provided between the elastic sleeve 462 and the rigid inner ring 461. The cavity formed between the elastic sleeve 462 and the rigid inner ring 461 is filled with gas 465. A set of threaded rods 42 corresponds to several sets of hollow posts 41 and detection rings 46. The number of hollow posts 41 and detection rings 46 is a multiple of three. The hollow posts 41 are arranged in an array around the axis of the threaded rods 42. The movable kit 44 and the threaded rods 42 are... The connection is threaded, and the diameter of the through hole 48 is equal to the diameter of the guide rod 43. The detection ring 46 is movably sleeved on the outer surface of the single battery 3. The lower end of the single battery 3 matches the interior of the hollow column 41. The number of detection rings 46 is equal to the number of hollow columns 41, and the positions of the detection rings 46 and hollow columns 41 correspond one-to-one. There are three sets of guide rods 43, which are arranged in a ring array around the axis of the threaded rod 42. The protrusion 47 is only provided on the outside of the detection ring 46 closest to the guide rod 43 in a counterclockwise direction, and the two adjacent sets of detection rings 46 are in tangential line contact. The inner diameter of the push spring 464 is greater than 100 mm. The push-up column 463 and the push-up spring 464 are in several groups, and the axis of the push-up column 463 coincides with the axis of the push-up spring 464. The several groups of push-up columns 463 are distributed in a ring array. The gas 465 is carbon dioxide, and the elastic sleeve 462 is made of elastic rubber material. The end of the drive motor 49 is equipped with a motor stroke monitoring system 13, which is used to monitor the stroke of the protrusion 47. The drive motor 49 and the motor stroke monitoring system 13 are connected by a signal. The end signal connection of the motor stroke monitoring system 13 is a mobile phone, a computer and a vehicle machine.

[0039] During use, the drive motor 49 drives the threaded rod 42 to rotate clockwise, causing the movable component 44 to move upward along the threaded rod 42. The detection ring 46 is initially positioned in the middle of the single battery 3, and simultaneously slides upward on the outer surface of the single battery 3. When the detection ring 46 slides to the top of the outer surface of the single battery 3, the drive motor 49 begins to rotate counterclockwise until the lower end of the detection ring 46 moves to the upper end of the hollow column 41. Then, the drive motor 49 rotates clockwise again until the detection ring 46 is in the middle of the single battery 3. When the drive motor 49 rotates to drive the movable kit 44, the fixed plate 45, the detection ring 46 and the protrusion 47 at the bulge, the movement of the detection ring 46 will stop. At this time, the drive motor 49 will stop rotating. During the rotation of the drive motor 49, the operation of the drive motor 49 is monitored by the motor stroke monitoring system 13. By monitoring the operation of the drive motor 49, it can be determined whether the outer surface of a single battery 3 has bulged. This allows the user to notice the bulging of a single battery 3 in time, and perform maintenance operations such as replacement and repair of the bulging battery.

[0040] During the up-and-down movement of the detection ring 46, the protrusion 47 can be movably sleeved on the outer surface of the guide rod 43 to guide the up-and-down movement of the detection ring 46, making the movement process more precise.

[0041] Meanwhile, the principle of the motor stroke monitoring system 13 for monitoring the running stroke of the drive motor 49 is the same as that of the existing technology, and it can also be replaced by existing motor stroke monitoring devices. That is, any system or device that can perform the function of monitoring the running stroke of the motor is acceptable.

[0042] During use, adjacent sets of detection rings 46 are tangent to each other. The outermost elastic sleeve 462 ensures line contact between adjacent detection rings 46. The supporting action of the jacking column 463 and jacking spring 464 ensures a more even distribution of the compressive force between the detection rings 46, thus protecting the individual battery 3 during movement and ensuring its stability.

[0043] During use, the outer surface of a single battery 3 can be automatically detected. When bulging occurs, the stroke of the drive motor 49 can be used to determine whether a single battery 3 has bulged. This allows for timely replacement of the bulging battery, thus avoiding potential dangers caused by battery bulging.

[0044] Example 3

[0045] like Figure 1 and Figure 7As shown, based on embodiment 2, a protective structure 5 is further proposed, including a movable plate 51 slidably connected to the outer surface of the inner wall at both ends of the outer shell 1. A connecting hole 52 is provided on the outer surface of the movable plate 51. A protruding plate 53 is fixedly connected to the outer surface of the movable plate 51. A movable spring 54 is connected between the protruding plate 53 and the inner wall of the outer shell 1. Limiting plates 55 are fixedly connected to the upper and lower edges of the movable plate 51 on the inner wall of the outer shell 1. An end guide plate 56 is fixedly connected to the lower inner wall of the outer shell 1 near the through hole 6. Side guide plates 57 are fixedly connected to the inner wall of the outer shell 1 near both sides. The movable spring 54 is a spring that expands in summer and contracts in winter. The expansion and contraction of the movable spring 54 causes the movable plate 51 to move, thereby increasing or decreasing the size of the opening between the connecting hole 52 and the through hole 6 until it is closed. The limiting plates 55 control the movement of the movable plate 51. The movement of the movable plate 51 serves as a guide. The movable plate 51 slides along the length of the limiting plate 55. There are three sets of protruding plates 53, and the spacing between two adjacent sets of protruding plates 53 is equal. There are three sets of through holes 6 at one end of the outer shell 1. The number of movable plates 51 is equal to the number of through holes 6. There are two sets of end guide plates 56, which are arranged in an inverted "eight" shape. The side with the larger opening of the two sets of end guide plates 56 is close to the connecting hole 52 at the end of the connecting hole 52. There are two sets of side guide plates 57, which are arranged in an array. The side guide plates 57 are arranged in a symmetrical oblique distribution structure, and the side with the larger opening faces the same direction as the side with the larger opening of the end guide plate 56. Only two sets of end guide plates 56 are provided inside the outer shell 1 near one end.

[0046] When using this battery pack in the hot summer, the movable spring 54 will collide when heated. The movable spring 54 pushes the protruding plate 53, and the protruding plate 53 drives the movable plate 51 to move away from the movable spring 54. At this time, the connecting hole 52 and the through hole 6 will gradually become connected from being disconnected. As the movable spring 54 heats up, it will push the movable plate 51 and the through hole 6 to be fully connected, so that both ends of the outer shell 1 are connected to the outside. At this time, the heat inside the outer shell 1 will flow outward under the action of convection, thereby forming a ventilation effect and preventing the temperature inside the outer shell 1 from getting too high. Conversely, in a colder environment, the movable spring 54 will contract, so that the opening formed by the connecting hole 52 and the through hole 6 will gradually shrink until it is closed, thereby preventing the outer shell 1 from being connected to the outside. The battery itself will generate a certain amount of heat, which will form a heat preservation effect inside the outer shell 1, thereby making the battery pack more durable and reducing the loss of the battery due to overheating or overcooling, effectively extending the service life of the battery pack.

[0047] In hot environments, the openings of the through hole 6 and the connecting hole 52 are connected. When the entire battery pack moves, the wind will blow in from the end near the end guide plate 56 and blow directly to several individual batteries 3. At the same time, the side guide plate 57 can guide the wind to prevent it from flowing away from the two sides inside the outer casing 1 and blow it directly to the individual batteries 3. At the same time, the interval of the detection ring 46 can make a certain gap between the individual batteries 3, thereby making the cooling effect better.

[0048] In hot weather conditions such as summer, the casing 1 can maintain ventilation for the individual battery 3 inside, thereby reducing the heat generated by the battery. At the same time, in cold weather conditions such as winter, the casing 1 can maintain the heat preservation of the individual battery 3 inside, making the individual battery 3 perform better and reducing the loss of the individual battery 3 due to overheating or overcooling, thus avoiding the occurrence of shortened lifespan of the individual battery 3.

[0049] In summary, during use, the drive motor 49 drives the threaded rod 42 to rotate clockwise, causing the movable component 44 to move upward along the threaded rod 42. The detection ring 46 is initially positioned at the center of the single battery 3, and simultaneously slides upward on the outer surface of the single battery 3. When the detection ring 46 slides to the top of the outer surface of the single battery 3, the drive motor 49 begins to rotate counterclockwise until the lower end of the detection ring 46 moves to the upper end of the hollow column 41. Then, the drive motor 49 rotates clockwise again until the detection ring 46 is in the center of the single battery 3. When the bulges appear at the moving parts 44, 45, 46, and 47, the movement of the 46 will stop and the drive motor 49 will stop rotating. During the rotation of the drive motor 49, the motor stroke monitoring system 13 monitors the operation of the drive motor 49. By monitoring the operation of the drive motor 49, it can be determined whether the outer surface of a single battery 3 has bulged. Users can observe the abnormal operation of the drive motor 49 through mobile phones, computers, or vehicle systems, so that users can discover the bulging of a single battery 3 in time and perform maintenance operations such as replacement and repair of the bulging battery in time.

[0050] It should be noted that during the up-and-down movement of the detection ring 46, the protrusion 47 can be movably sleeved on the outer surface of the guide rod 43 to guide the up-and-down movement of the detection ring 46, which can make the movement process more accurate.

[0051] It should be noted that the principle of the motor stroke monitoring system 13 for monitoring the running stroke of the drive motor 49 is the same as that of the existing technology, and can also be replaced by existing motor stroke monitoring devices. That is, any system or device that can perform the function of monitoring the running stroke of the motor is acceptable.

[0052] During use, the two adjacent sets of detection rings 46 are in a tangent state. The outermost elastic sleeve 462 can make the adjacent detection rings 46 in line contact. With the support of the push column 463 and the push spring 464, the squeezing force between the detection rings 46 can be distributed more evenly, thereby protecting the individual battery 3 during the movement of the individual battery 3 and ensuring the stability of the individual battery 3 during the movement process.

[0053] When the battery pack is used in hot summer, the movable spring 54 will collide when heated. The movable spring 54 pushes the protruding plate 53, and the protruding plate 53 drives the movable plate 51 to move away from the movable spring 54. At this time, the connecting hole 52 and the through hole 6 will gradually become connected from being disconnected. As the movable spring 54 heats up, it will push the movable plate 51 and the through hole 6 to be fully connected, so that both ends of the outer shell 1 are connected to the outside. At this time, the heat inside the outer shell 1 will flow outward under the action of convection, thereby forming a ventilation effect and preventing the temperature inside the outer shell 1 from getting too high. Conversely, in a colder environment, the movable spring 54 will contract, so that the opening formed by the connecting hole 52 and the through hole 6 will gradually shrink until it is closed, thereby preventing the outer shell 1 from being connected to the outside. The battery itself will generate a certain amount of heat, which will form a heat preservation effect inside the outer shell 1, thereby making the battery pack more durable and reducing the loss of the battery due to overheating or overcooling, effectively extending the service life of the battery pack.

[0054] It should be noted that in hot environments, the openings of the through hole 6 and the connecting hole 52 are connected. When the entire battery pack is moving, the wind will blow in from the end near the end guide plate 56 and blow directly to several individual batteries 3. At the same time, the side guide plate 57 can guide the wind to prevent it from flowing away from the two sides inside the outer casing 1 and can blow directly to the individual batteries 3. At the same time, the interval of the detection ring 46 can make a certain gap between the individual batteries 3, thereby making the cooling effect better.

[0055] It should be noted that when moving, the ventilation effect is best when the air enters from the end with the end guide plate 56.

[0056] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
