Description

Technical Field

[0001] The present invention relates to the technical field of power boxes, and specifically to a heat dissipation power box structure. Background Art

[0002] The basic function of a power box is to accommodate and protect a battery pack. Its structure must ensure sufficient strength while retaining the largest accommodation space. At the same time, during the charging and discharging process of the battery, a large amount of heat is generated, which affects the charging and discharging performance of the battery. Considering the safety of battery use, battery manufacturers often artificially reduce the charging and discharging current when the temperature is higher than a certain level to achieve the purpose of safe use. The result is that the battery usage efficiency is greatly reduced. There is an urgent need to cool the battery during the use of the battery. Therefore, the heat dissipation power box structure is widely used. However, in the existing heat dissipation power box structure, heat dissipation is generally carried out through a fan and heat dissipation holes. On the one hand, its heat dissipation efficiency is low.

The following describes each embodiment of the present invention in detail with reference to the drawings.

[0027] Embodiment 1

[0028] Please refer to Figures 1 to 9, the present invention preferably provides a technical solution: a heat dissipation power supply box structure, including: a power supply box body 1, and two mounting plates 4 fixed in the middle of the power supply box body 1. A shock absorption support assembly is arranged at the lower part of the two mounting plates 4 for placing the main battery pack; it also includes a fan assembly arranged on the opposite surfaces of the two mounting plates 4 for dissipating heat from the main battery pack; and two groups of mounting strips 15 arranged on the inner wall of the power supply box body 1. A cover plate 2 is also installed at the top of each group of mounting strips 15. The lower part of each group of mounting strips 15 is rotatably installed through a mounting shaft 26, and a heat dissipation through-plate assembly is arranged between each group of mounting strips 15 for air flow to enter; two groups of belt drive assemblies are also arranged inside the power supply box body 1 for the coordinated operation of the corresponding fan assembly and the heat dissipation through-plate assembly; the shock absorption support assembly, the two heat dissipation through-plate assemblies, the two mounting plates 4, and the two cover plates 2 at the top of the power supply box body 1 together enclose a cavity for placing the main battery pack.

[0029] Through the power provided by the belt drive assembly, the fan assembly and the heat dissipation through-plate assembly can operate in coordination, that is, dissipate heat from the main battery pack placed on the shock absorption support assembly. Through the setting of this structure, with different driving degrees, there are two heat dissipation methods, specifically as Figure 1 , Figure 3 shown;

[0030] That is, heat dissipation in the normal operating state of the main battery pack: At this time, through the power provided by the belt drive assembly, the heat dissipation through-plate assembly can be gradually opened. This gradually opening method can be selected from top to bottom or from bottom to top. Here, it is preferably from top to bottom, as Figure 5 shown. Further, with the cooperation of the fan assembly, the air flow gradually fills the inside of the cavity, dissipates heat from the battery, and discharges the hot air in the cavity to the outside. Through the continuous coordinated action of the fan assembly and the heat dissipation through-plate assembly, the air in the cavity can continuously flow, thereby realizing heat dissipation of the main battery pack placed in the cavity;

[0031] When the operation of the main battery pack is abnormal: that is, when the internal temperature and water vapor of the main battery pack exceed their extreme values, it can drive the mounting strip 15 to deflect away from the mounting plate 4 around the mounting shaft 26. At this time, the two heat dissipation through-plate assemblies open to both sides, and at the same time drive the two cover plates 2 to separate, exposing the main battery pack, reducing the subsequent impact caused by high temperature and water vapor.

[0032] Furthermore, each set of heat dissipation through-plate assemblies includes a mounting frame 46 fixed to the side wall of each set of mounting bars 15. A linearly distributed movable shaft 29 is rotatably mounted on the mounting frame 46. A through-plate body 28 is fixed to the outer wall of each movable shaft 29. The side walls of adjacent through-plate bodies 28 are provided with inclined surfaces for the overlapping of the through-plate bodies 28. It also includes outer gear rings 30 respectively arranged at both ends of the movable shaft 29. A limiting groove 36 is formed in each mounting bar 15, and a movable block 25 sliding inside the limiting groove 36 is provided. A mounting member 31 is also fixed to the side wall of the movable block 25. The mounting member 31 passes through a through-hole formed in the side wall of the mounting bar 15 and is fixed with a rack 45. The rack 45 meshes with the outer gear ring 30.

[0033] Through the action of the belt transmission assembly, the movable block 25 can be limited to slide up and down inside the limiting groove 36. Cooperating with the rack 45 provided by the movable block 25 through the mounting member 31 meshing with the outer gear ring 30, several through-plate bodies 28 can be opened and closed step by step, as Figure 5 shown. When it is necessary to dissipate heat from the main battery pack, the movable block 25 is moved downward inside the limiting groove 36. At this time, the rack 45 can contact the linearly arranged outer gear rings 30 from top to bottom in turn. Further, due to the setting of the inclined surface at the end of the through-plate body 28, when the rack 45 moves and meshes with the corresponding outer gear ring 30 in turn, several through-plate bodies 28 are further deflected and opened in turn, so that the external air flow enters the inside of the cavity step by step through the gap between each set of mounting bars 15 to dissipate heat from the main battery pack. Similarly, when the movable block 25 moves upward inside the limiting groove 36, several through-plate bodies 28 can be closed from bottom to top in turn.

[0034] Furthermore, the fan assembly includes mounting grooves 39 respectively formed in the side wall of the power supply box body 1, and the mounting grooves 39 penetrate through the side wall of the mounting plate 4. A cross plate 19 is fixed inside each mounting groove 39, and a fan body 17 rotatably arranged in the middle of the cross plate 19 is provided. A one-way bearing 12 is also arranged at the end of the fan body 17.

[0035] In this embodiment, the fan body 17 is preferably an exhaust fan, which sucks the hot air in the cavity to the outside through the mounting groove 39, so as to dissipate heat from the main battery pack in the cavity. Specifically, as Figure 1 shown, through the power provided by the belt transmission assembly and the cooperation of the one-way bearing 12, the fan body 17 can rotate intermittently. When the fan body 17 stops operating, several through-plate bodies 28 are closed at this time, which can make the outside cold air flow stay in the cavity for a period of time and fill the corners of the cavity. Through the synergistic effect of the two, when the fan body 17 operates and cooperates with the through-plate bodies 28 where the heat dissipation through-plate assemblies are located to be opened step by step in turn, the hot air can be pumped out to the outside of the power supply box body 1 while transporting the external air to the inside of the cavity. Such a cycle is carried out to achieve the rapid heat dissipation of the battery pack.

[0036] Further, the belt drive assembly includes a first drive wheel 13, a second drive wheel 20, and a third drive wheel 21 that are respectively rotatably mounted on the inner wall of the power supply box body 1, and the first drive wheel 13, the second drive wheel 20, and the third drive wheel 21 are arranged in a triangular distribution, and a drive belt 37 that is rotatably connected between the first drive wheel 13, the second drive wheel 20, and the third drive wheel 21. The side wall of the drive belt 37 is rotatably connected to the movable block 25 through a pin shaft; a drive belt 14 is transmission-connected between the end of the first drive wheel 13 and the one-way bearing 12 through a through hole opened on the power supply box body 1. It further includes a motor 10 fixed on the side wall of the power supply box body 1, and the end of the output shaft of the motor 10 passes through a through hole opened on the power supply box body 1 and is fixed to the third drive wheel 21.

[0037] In this embodiment, the first drive wheel 13, the second drive wheel 20, and the third drive wheel 21 are arranged in a triangular distribution, and the first drive wheel 13 and the third drive wheel 21 are on the same vertical line, and this vertical line is perpendicular to the horizontal part of the power supply box body 1. The setting state is as Figure 3 shown. Through the action of the motor 10 and the rotation of the drive belt 37, when it is necessary to dissipate heat from the main battery pack placed in the cavity, by the back-and-forth micro-rotation of the motor 10, the drive belt 37 is driven back and forth, and the driving distance is maintained between the first drive wheel 13 and the third drive wheel 21, that is, the movable block 25 always moves up and down inside the drive belt 37. At the same time, the mounting strip 15 remains in a vertical state, so that the rack 45 can be successively engaged with the external gear ring 30 back and forth to drive, thereby realizing the back-and-forth opening and closing of the through plate body 28, and further dissipating heat from the main battery pack in the cavity, as Figure 1 shown. At the same time, due to the driving action of the drive belt 14 and in cooperation with the action of the one-way bearing 12, the fan body 17 is intermittently sucked.

[0038] Embodiment 2

[0039] As another implementation manner of the present invention, the outer wall of the third drive wheel 21 is provided with a memory alloy member 43 arranged in a ring, and a rotating roller 44 is provided at the end of each memory alloy member 43 to facilitate the conveying of the drive belt 37.

[0040] In this embodiment, due to the material characteristics of the memory alloy member 43, the memory alloy member 43 is a material composed of two or more metal elements that has a shape memory effect through thermoelasticity and martensitic phase transformation and its reverse transformation. Its working principle is similar to that of a memory alloy spring. When this spring is placed in hot water, the length of the spring immediately elongates, and when it is placed in cold water, it will immediately return to its original state, as Figure 5As shown in the figure, when the overall temperature inside the power supply box body 1 rises, the length of the shape memory alloy piece 43 where the third driving wheel 21 is located elongates, which is equivalent to an increase in the overall radius of the third driving wheel 21. According to the formula v = ωr, when r increases, since the output power of the motor 10 remains unchanged, that is, ω corresponding to the third driving wheel 21 remains unchanged, the linear velocity v of the transmission belt 37 increases, thereby making the sliding speed of the movable block 25 inside the limit groove 36 faster, and further making the opening and closing rate of the through plate body 28 faster. At the same time, the angular velocity of the first driving wheel 13 increases, and through the transmission of the transmission belt 14, the rotation speed of the fan body 17 is accelerated. This process realizes the adaptive change of temperature and air flow, that is, when the temperature rises, the air flow velocity accelerates. Similarly, when the internal temperature of the power supply box body 1 is relatively low, the air flow velocity is slower, so that the heat dissipation effect can be synchronized when the main battery pack is working and not working.

[0041] Embodiment 3

[0042] As other embodiments of the present invention, a temperature sensor 38 and a humidity sensor 41 are respectively provided on the inner wall of the mounting plate 4, and the humidity sensor 41 is placed below the main battery pack.

[0043] As Figure 4 shown in the figure, when an abnormality occurs in the operation of the main battery pack, that is, when the internal temperature of the main battery pack exceeds its extreme value, through the action of the temperature sensor 38 on the mounting plate 4, the through plate body 28 can control the motor 10 to rotate in one direction. At this time, the transmission distance of the transmission belt 37 is greater than the distance between the third driving wheel 21 and the first driving wheel 13, so that the movable block 25 moves downward within the limit of the transmission belt 37, that is, inside the limit groove 36. When it passes over the third driving wheel 21, it can drive the mounting strip 15 to deflect away from the mounting plate 4 around the mounting shaft 26, further causing the cover plate 2 on the mounting strip 15 to open, exposing the main battery pack, reducing the subsequent impact of high temperature on it, and improving its service life. Similarly, when the internal humidity of the power supply box body 1 exceeds the extreme value set by the humidity sensor 41, through the action of the humidity sensor 41, the above process is triggered, and this process reduces the subsequent impact of water vapor on the main battery pack.

[0044] Embodiment 4

[0045] As other embodiments of the present invention, guide rods 27 are fixed to the bottoms of both mounting strips 15, and electric plates are provided at the opposite ends of the two guide rods 27 for powering on the main battery pack when the ends of the two guide rods 27 come into contact.

[0046] When the motor 10 makes fine adjustments back and forth, that is, when the two mounting strips 15 are in a vertical state, as Figure 5As shown, at this time, the ends of the two guide rods 27 are in contact, and the main battery pack is powered on, that is, the main battery pack is working normally. When there is an abnormality inside the main battery pack, such as when the cavity temperature or the humidity inside the power supply box body 1 exceeds the extreme values of the temperature sensor 38 or the humidity sensor 41 respectively, when the two mounting strips 15 deflect away from the mounting plate 4, the electric sheets at the ends of the two fan bodies 17 can be separated, that is, the main battery pack is powered off, improving its safety and reducing the occurrence of fires and other situations.

[0047] Embodiment 5

[0048] As other embodiments of the present invention, the shock-absorbing support assembly includes support plates 35 respectively fixed on the side walls of the two mounting plates 4, and mounting frames 48 arranged to telescopically move on the support plates 35. The two mounting frames 48 respectively pass through through holes opened at both ends of the corresponding support plates 35 and are fixed with cross plates 33. A plurality of grooves 47 are also opened on the cross plates 33 for heat dissipation; it also includes a plurality of second springs 34 connected between the inner top surface of the mounting frame 48 and the upper surface of the support plate 35.

[0049] When the main battery pack is placed on the upper surface of the cross plate 33, as Figure 5 shown, at this time, through the action of the second springs 34, the main battery pack can be shock-absorbed, reducing the collision between the battery pack and the through plate body 28 and the inner wall of the mounting plate 4 during transportation;

[0050] Furthermore, the upper surface of the mounting frame 48 is fixedly connected with oppositely arranged elastic ropes 32, and two fixed pulleys 40 are also fixed on the inner wall of the mounting plate 4. One end of the elastic rope 32 away from the mounting frame 48 passes through the outer wall of the fixed pulley 40 and extends to the top of the mounting strip 15 and is fixedly connected thereto;

[0051] As Figure 3 shown, at this time, it is in the normal working state, and the elastic rope 32 is in a relaxed state. The shock-absorbing process is not affected by the elastic rope 32. When the main battery pack has an abnormality, that is, when the two mounting strips 15 deflect away from the mounting plate 4, at the same time, the elastic rope 32 changes from a relaxed state to a straightened state, and the main battery pack located on the upper surface of the cross plate 33 can be lifted, making it better exposed to the outside and reducing the further influence of fire or water vapor inside the box.

[0052] Further, an installation box 5 is fixed to the side wall where each group of installation bars 15 is located. A liquid storage pipe 42 is loop - arranged inside the installation box 5. Both ends of the liquid storage pipe 42 extend to the top of the installation box 5 and are respectively connected to a liquid inlet 11 and a liquid outlet 16; and a piston suction assembly fixed to the bottom of the power box body 1 is used for the circulation of the refrigerant inside the liquid storage pipe 42. The piston suction assembly includes a piston sleeve 7 and a push plate 23 sliding inside the piston sleeve 7. A piston rod 9 is fixed to the upper surface of the push plate 23. One end of the piston rod 9 away from the push plate 23 passes through a through - hole opened on the piston sleeve 7 and is fixed with a pressing block 24. It also includes a first spring 8 connected between the lower surface of the pressing block 24 and the outer wall of the piston rod 9 on the upper surface of the piston sleeve 7 for the reset of the piston rod 9; and a collection box 22 arranged on the side wall of the piston sleeve 7 close to the installation bar 15 for collecting the refluxed refrigerant, and the collection box 22 is communicated with the lower part of the piston sleeve 7;

[0053] As Figure 1 、 Figure 6 shown, through the installation box 5 and the liquid storage pipe 42 arranged inside it, and the refrigerant is placed inside the liquid storage pipe 42. When the through - plate body 28 where the heat - dissipation through - plate assembly is located is opened, through the cooling effect of the installation box 5, the air flow entering the cavity can be cooled, thereby further improving the heat - dissipation effect on the main battery pack;

[0054] Through the action of the piston suction assembly, as Figure 3 shown, that is, the piston rod 9 can move telescopically inside the piston sleeve 7. With the cooperation of the first spring 8, and the piston sleeve 7 and the collection box 22 are respectively communicated with the liquid inlet 11 and the liquid outlet 16 through conduits. A first one - way valve flowing towards the liquid inlet 11 is arranged inside the conduit connecting the piston sleeve 7 and the liquid inlet 11, and a second one - way valve flowing towards the collection box 22 is arranged inside the conduit connecting the collection box 22 and the liquid outlet 16. As an implementation method for driving the piston suction assembly to operate, when pressing the piston rod 9 to move inside the piston sleeve 7 by hand, the push plate 23 can be made to move downward. With the cooperation of the first one - way valve and the second one - way valve, the refrigerant can enter the liquid storage pipe 42. At the same time, the used refrigerant in the liquid storage pipe 42 can be refluxed into the collection box 22. Then, with the cooperation of the first spring 8, the piston rod 9 can be reset. Through the reflux of the refrigerant, the cooling effect of the installation box 5 can be maintained, and further, it can be ensured that the air entering the cavity remains at a low temperature when the through - plate body 28 is opened.

[0055] Further, placing boxes 6 are respectively fixed to the opposite sides of the two installation boxes 5 for placing auxiliary battery packs; and a cover 3 is arranged on the top of the placing box 6.

[0056] As Figure 1As shown, the auxiliary battery pack placed inside the placement box 6 can be used as a backup battery or improve the overall power of the power supply. The design of the placement box 6 can also provide power for the piston rod 9 to move into the piston sleeve 7, such as Figure 5 As shown, when the two groups of mounting bars 15 deflect away from the mounting plate 4, the placement box 6 can then press against the pressure block 24, so that the piston rod 9 pushes the push plate 23 towards the bottom of the piston sleeve 7, thereby realizing the refrigerant reflux process.
