Description

Technical Field

[0001] This invention belongs to the field of battery technology, specifically relating to a high-safety battery module and a battery heat dissipation mechanism. Background Technology

[0002] A battery module is a unit composed of multiple battery cells connected in series, parallel, or series-parallel configurations. It is an intermediate level between battery cells and battery systems. A battery module has an outer casing to protect the internal battery cells, as well as some connecting components to ensure good electrical connection between the batteries, thereby enabling the output of stable voltage and current. Battery modules are mainly used to provide power to various devices, such as electric vehicles and energy storage systems.

[0003] Existing solutions typically place battery modules together in a single enclosure to supply power to electrical appliances. However, the heat generated by multiple batteries can be excessive. If the heat exceeds the battery's tolerance, it will be damaged. Furthermore, if one battery fails, the power supply to adjacent batteries will be interrupted, causing short circuits and other problems, which in turn will damage the adjacent batteries as well. Summary of the Invention

[0004] The purpose of this invention is to provide a high-safety battery module and battery heat dissipation mechanism to solve the technical problem that multiple batteries generate a lot of heat and that the batteries affect each other, and that the failure of one battery will also damage other batteries. The invention achieves the goal of completely separating each battery and dissipating the generated heat, thereby facilitating the stable operation of multiple batteries.

[0005] To solve the above-mentioned technical problems, the present invention provides a high-safety battery module, comprising: a first housing, wherein at least one heat insulation component is disposed in the first housing, and adjacent heat insulation components are horizontally arranged at equal intervals, wherein the heat insulation component includes a battery and a heat-conducting sheet;

[0006] The second housing has its side wall connected to the side wall of the first housing. One end of the heat-conducting sheet is connected to the battery, and the other end of the heat-conducting sheet extends through the side walls of the first housing and the second housing into the second housing.

[0007] Furthermore, the heat insulation assembly also includes a heat insulation box and a heat insulation cover. The heat insulation box has a threaded hole, and the heat insulation cover has a round hole. The heat insulation cover is threadedly connected to the heat insulation box by screws passing through the round hole and the threaded hole in sequence.

[0008] Furthermore, a first lid is provided at the top of the first box body, and a pull frame is provided at the top of the first lid;

[0009] A fixing plate is horizontally arranged inside the first housing, and the heat insulation components are all located on the upper surface of the fixing plate.

[0010] Furthermore, a heat-conducting box is provided between the heat insulation box and the battery, and the heat-conducting box is in contact with the battery;

[0011] The heat-conducting sheet passes through the fixing plate and the heat insulation box in sequence and is connected to the heat-conducting box to conduct the heat of the battery. A heat insulation plate is attached to the side of the heat-conducting sheet close to the adjacent heat-conducting sheet.

[0012] The heat-conducting plate has multiple fins on the side away from the heat insulation plate, and all of the multiple fins are located inside the second housing.

[0013] Furthermore, a second cover is provided at the top of the second box, heat dissipation holes are provided on the side wall of the second box, and two vertical first grooves are provided on the inner wall of the second box.

[0014] A battery heat dissipation mechanism includes: a drive component, a heat dissipation component, and a high-safety battery module as described in any one of the above, wherein the drive component and the heat dissipation component are both disposed in the second housing.

[0015] Furthermore, the drive assembly includes a threaded rod and a slider. The threaded rod is disposed parallel to the two first sliding grooves, and the sidewall of the slider slides within the two first sliding grooves. The slider is sleeved on the outside of the threaded rod and slidably connected to the threaded rod.

[0016] Furthermore, a motor is installed inside the second cover, and the output shaft of the motor passes through the second cover and the second housing in sequence and is coaxially connected to the threaded rod.

[0017] Furthermore, a second groove is provided on the slider, and a horizontal rack is slidably disposed in the second groove;

[0018] The slider is provided with a horizontal hydraulic rod, and the output shaft of the hydraulic rod extends into the second slide groove and connects to the rack.

[0019] A controller is provided on the side wall of the first housing, which is used to control the motor and the hydraulic rod.

[0020] Furthermore, the heat dissipation assembly includes a mounting plate and a fan, and the sidewall of the mounting plate is rotatably connected to the sidewall of the slider;

[0023] The beneficial effects of this invention are:

[0024] 1. This invention, by setting up a heat insulation component, places the battery in a heat insulation box and a heat conduction box in sequence. The heat of the battery is transferred to the heat conduction box, and the heat conduction sheet contacts the heat conduction box to transfer the heat to the second box and dissipate it through the heat dissipation holes, thereby reducing the temperature of the battery, ensuring the stability of battery operation, and improving the service life.

[0025] 2. This invention incorporates a heat dissipation component. A motor drives a threaded rod to rotate, which in turn drives a fan to move up and down. The fan blows air from the second housing, expelling heat through the heat dissipation holes. A hydraulic rod pushes a rack, which in turn drives the fan to rotate, thereby changing the direction of the fan and improving the uniformity and efficiency of heat dissipation.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Example 1:

[0040] like Figures 1 to 7 As shown, a high-safety battery module includes: a first housing 1 and a second housing 2. At least one heat insulation component 4 is provided inside the first housing 1. Adjacent heat insulation components 4 are arranged horizontally at equal intervals and do not affect each other. The heat generated by the battery 41 is blocked by the heat insulation component 4 to prevent damage to other batteries 41 due to damage to one battery 41. A first housing cover 11 is provided at the top of the first housing 1, and a pull frame 12 is provided at the top of the first housing cover 11. A fixing plate 3 is horizontally arranged inside the first housing 1, and the heat insulation components 4 are all located on the upper surface of the fixing plate 3.

[0041] like Figure 4 As shown, the heat insulation component 4 includes a battery 41 and a heat-conducting sheet 42; the heat insulation component 4 also includes a heat insulation box 43 and a heat insulation cover 44. The heat insulation box 43 has a threaded hole 431, and the heat insulation cover 44 has a round hole 441. The heat insulation cover 44 is threadedly connected to the heat insulation box 43 by screws 442 passing through the round hole 441 and the threaded hole 431 in sequence. The threaded hole 431 and the round hole 441 are coaxially arranged. The heat insulation box 43 and the heat insulation cover 44 can be installed or removed by screwing in or unscrewing the screws 442, which facilitates the installation of the battery 41 in the heat insulation box 43 and the removal of the battery when it is necessary to inspect or replace the battery 41.

[0042] In this embodiment, a heat-conducting box 411 is provided between the heat insulation box 43 and the battery 41. The heat-conducting box 411 is in contact with the battery 41, and the heat generated by the battery 41 is absorbed by the heat-conducting box 411. The heat-conducting sheet 42 passes through the fixing plate 3 and the heat insulation box 43 in sequence and is connected to the heat-conducting box 411 to conduct the heat of the battery 41. The heat-conducting sheet 42 contacts the heat-conducting box 411 and absorbs the heat transferred from the battery 41 to the heat-conducting box 411. A heat insulation plate 421 is attached to the side of the heat-conducting sheet 42 close to the adjacent heat-conducting sheet 42. The heat insulation plate 421 blocks the heat on the heat-conducting sheet 42 and prevents the heat transfer between adjacent heat-conducting sheets 42 from increasing the heat of the battery 41.

[0043] like Figure 7 As shown, the side wall of the second housing 2 is connected to the side wall of the first housing 1. The top of the second housing 2 is provided with a second housing cover 21. The side wall of the second housing 2 is provided with heat dissipation holes 22. The inner wall of the second housing 2 is provided with two vertical first sliding grooves 23. One end of the heat-conducting plate 42 is connected to the battery 41. The other end of the heat-conducting plate 42 extends through the side walls of the first housing 1 and the second housing 2 into the second housing 2. The heat-conducting plate 42 absorbs and transfers the heat on the heat-conducting box 411 into the second housing 2. The heat is discharged through the heat dissipation holes 22 on the second housing 2, thereby reducing the heat of the battery 41. Multiple fins 422 are provided on the side of the heat-conducting plate 422 away from the heat insulation plate 421. The multiple fins 422 are all located in the second housing 2. The fins 422 accelerate the dissipation of heat on the heat-conducting plate 42 and improve the heat discharge efficiency.

[0044] Example 2:

[0045] like Figure 3 and Figure 8 As shown, based on the high-safety battery module of Embodiment 1, this embodiment provides a battery heat dissipation mechanism, including: a drive component 5, a heat dissipation component 6 and the high-safety battery module of Embodiment 1. Both the drive component 5 and the heat dissipation component 6 are disposed in the second housing 2.

[0046] Among them, such as Figure 3 As shown, the drive assembly 5 includes a threaded rod 51 and a slider 52. The threaded rod 51 is arranged parallel between two first sliding grooves 23. The sidewall of the slider 52 slides within the two first sliding grooves 23. The slider 52 is sleeved on the outside of the threaded rod 51 and slidably connected to the threaded rod 51. A motor 53 is installed inside the second cover 21. The output shaft of the motor 53 passes through the second cover 21 and the second box body 2 in sequence and is coaxially connected to the threaded rod 51. The motor 53 drives the threaded rod 51 to rotate, and the slider 52 moves up and down along the vertical threaded rod 51. The two ends of the slider 52 slide within the first sliding grooves 23, which improves the stability of the slider 52 during the sliding process and prevents the slider 52 from shaking and falling.

[0047] like Figure 8As shown, the heat dissipation assembly 6 includes a mounting plate 61 and a fan 62. The side wall of the mounting plate 61 is rotatably connected to the side wall of the slider 52. The slider 52 has a horizontal second slide groove 521, and a horizontal rack 55 is slidably arranged in the second slide groove 521. A horizontal hydraulic rod 54 is provided on the slider 52. The output shaft of the hydraulic rod 54 extends into the second slide groove 521 and connects with the rack 55. The hydraulic rod 54 pushes the rack 55 to move horizontally.

[0048] In this embodiment, one end of the mounting plate 61 is connected to a gear 63 via a rotating column 631. The gear 63 meshes with a rack 55. When the rack 55 moves, the gear 63 rotates accordingly, thereby driving the mounting plate 61 to rotate. The other end of the mounting plate 61 is connected to a fan 62. The fan 62 is driven by the mounting plate 61 to move up and down to blow air and dissipate heat. At the same time, the fan 62 follows the rotation of the mounting plate 61 to change the air blowing direction, making the heat dissipation more uniform. When the slider 52 moves up and down, it drives the mounting plate 61 to move up and down. A controller 13 is provided on the side wall of the first housing 1. The controller 13 is used to control the start of the motor 53 and the hydraulic rod 54.

[0049] In summary, when the high-safety battery module is working, the heat generated by the battery 41 is absorbed by the heat-conducting box 411. The heat-conducting plate 42 transfers the heat absorbed from the heat-conducting box 411 to the second box 2. The fins 422 accelerate the heat dissipation of the heat-conducting plate 42 and transfer it out through the heat dissipation holes 22. The controller 13 controls the motor 53 and the hydraulic rod 54 to start. The motor 53 drives the threaded rod 51 to rotate, thereby driving the slider 52 to move up and down. At the same time, the gear 63 rotates on the rack 55 to change the direction of the fan 62, so as to achieve rapid and uniform heat dissipation.
