Description

Technical Field

[0001] The present invention belongs to the technical field of battery cooling protection, and specifically relates to a new energy battery provided with a safety protection device. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources. For example, pure electric vehicles that rely entirely on built-in batteries and electric motors to provide power. Integrating advanced technologies in the power control and driving aspects of the vehicle, a vehicle with advanced technical principles, new technologies, and new structures is formed. Among them, the battery serving as the energy storage unit generates heat during use. To ensure the discharge capacity of the battery and safety requirements, the battery is often cooled.

[0003] Liquid cooling is a method that uses a coolant to flow in the pipelines inside the power battery, transferring the heat generated by the battery to the coolant, and then dissipating the heat to the outside through heat exchange. This heat dissipation method has high efficiency and can precisely control the temperature of the battery pack. However, existing cooling structures operate in fixed pipelines. When the battery collides or is overloaded and generates a maximum heat dissipation temperature far higher than the design of the cooler, the existing radiator lacks an emergency structure and cannot improve the heat dissipation effect and reduce the heat source in a short time, thus resulting in dangers such as fire and explosion. Therefore, there is an urgent need for a new energy battery provided with a safety protection device. Summary of the Invention

[0004] The purpose of the present invention is to provide a new energy battery provided with a safety protection device to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A new energy battery provided with a safety protection device, including a housing assembly, an energy storage assembly is fixedly installed inside the housing assembly, and further includes a linkage circulating cooling structure, which includes a fixing component fixedly installed in the middle of the energy storage assembly, a circulating component is fixedly installed on the right side of the housing assembly, and a cooling component is fixedly installed at the bottom of the fixing component;

[0006] Multiple splitting components, multiple splitting components are fixedly installed on the outer edge of the cooling component. The splitting component includes a circular tube, two groups of long slots are penetrated through the circular tube, hemispherical slots are opened in both groups of long slots, long rods are movably hinged on one side of both groups of long slots, second springs are penetrated through the sides of both groups of long rods away from the hinge, steel balls are elastically abutted on the upper and lower sides of both groups of second springs, and four groups of steel balls are movably clamped in the long rods.

[0007] Preferably, the housing assembly includes a frame. Two bottom plates are fixedly installed at the bottom of the frame. A hinge is movably hinged at the middle position of the two bottom plates. Two fixing blocks are fixedly connected to both the front and rear sides of the frame. A top plate is fixedly installed at the top of the frame. A plurality of reinforcing ribs are provided on the top of the top plate.

[0008] Preferably, the energy storage assembly includes two rubber strips. Both rubber strips are fixedly installed on the inner wall of the frame. Two battery cells are fixedly connected to the other side of the two rubber strips. Connection ports are provided on the top of the two groups of battery cells.

[0009] Preferably, the fixing assembly includes a cross-shaped block. The cross-shaped block is fixedly installed at the middle position of the two groups of battery cells. A round rod is installed through the longitudinal direction of the cross-shaped block. Two first springs are elastically connected in the transverse direction of the cross-shaped block. A plurality of T-shaped rings are movably sleeved on the outer edges of the two first springs.

[0010] Preferably, both ends of the round rod are fixedly connected to the inner wall of the frame. The other ends of the two first springs are fixedly connected to the inner wall of the frame. A plurality of T-shaped rings are fixedly connected to the outer sides of the two groups of battery cells.

[0011] Preferably, the circulation assembly includes a liquid storage and pressurization tank. The liquid storage and pressurization tank is fixedly installed on the right side of the frame. A liquid inlet pipe and a liquid outlet pipe are fixedly connected to the front side of the liquid storage and pressurization tank.

[0012] Preferably, the cooling assembly includes two fixing strips. Both fixing strips are fixedly installed on the inner wall of the frame. A plurality of C-shaped blocks are fixedly connected to the other side of the two fixing strips. A serpentine copper tube is installed through the middle position of the plurality of C-shaped blocks. A liquid inlet is fixedly connected to the right side of the serpentine copper tube. A liquid outlet is fixedly connected to the left side of the serpentine copper tube.

[0013] Preferably, the installation positions of the two fixing strips are below the two rubber strips. The bottoms of the plurality of C-shaped blocks are fixedly connected to the bottom plates. The liquid inlet is fixedly connected to the liquid inlet pipe. The liquid outlet is fixedly connected to the liquid outlet pipe.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. The present invention is equipped with a splitting component. When the battery cell collides and is damaged or generates a large amount of heat source due to overloading, by increasing the liquid outlet pressure of the liquid storage and pressurization tank, the liquid flow rate increases, the impact force on the pipe wall increases, and the pipe wall pressure increases. At this time, multiple long rods will be under pressure, and two steel balls will squeeze the second spring and move out from the clamping connection of the hemispherical groove. The long rods will rotate and open on the other side of the long groove. At this time, the coolant will quickly cover the cavity formed by the frame and the bottom plate, forming an emergency heat dissipation mode, solving the problem that the existing radiator lacks an emergency structure and cannot improve the heat dissipation effect in a short time, reduce the heat source, and thus generate risks such as fire and explosion.

[0016] 2. The present invention is equipped with a newly designed cross fixing component. When the bottom of the bottom plate is stressed, the energy storage component inside the housing component will also complete a slight movement under the support of the fixing component. The rubber strips installed on both sides of the battery cell allow flexible extrusion and displacement for a certain distance. And when multiple T-shaped rings installed on the other side of the battery cell are stressed, they will squeeze two first springs. The first springs will deform under stress, but will always exert a supporting force on the battery cell through multiple T-shaped rings, preventing the problem that the traditional support structure cannot fix the battery cell after being stressed by collision.

[0017] 3. The present invention is equipped with a variable bottom plate. The frame, bottom plate, and top plate together form a sealed protective shell for the battery cell, and the whole can be installed through two groups of fixing blocks. When the bottom plate touches and collides, it will bend to both sides along the hinge, allowing the entire frame to bend along the gap position of the battery cell, reducing the irregular force directly on the battery cell when the housing component is stressed, and thus reducing the damage risk.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] like Figures 1 to 7 As shown, an embodiment of the present invention provides a new energy battery with a safety protection device, including a shell component 1, an energy storage component 2 is fixedly installed inside the shell component 1, and a linked circulation cooling structure includes a fixed component 3, the fixed component 3 is fixedly installed in the middle of the energy storage component 2, a circulation component 4 is fixedly installed on the right side of the shell component 1, and a cooling component 5 is fixedly installed at the bottom of the fixed component 3;

[0028] Multiple split components 6, all of which are fixedly mounted on the outer edge of the cooling component 5, the split components 6 include a round tube 61, the round tube 61 is penetrated with two groups of long grooves 62, the two groups of long grooves 62 are each provided with a hemispherical groove 63, one side of the two groups of long grooves 62 is movably hinged with a long rod 64, the two groups of long rods 64 are penetrated and installed with a second spring 65 on the side away from the hinge, the upper and lower sides of the two groups of second springs 65 are elastically abutted with steel balls 66, and the four groups of steel balls 66 are movably clamped in the long rod 64;

[0029] When the battery cell 22 is damaged by collision or generates a large amount of heat source due to overloading, the liquid outlet pressure of the liquid storage and pressurization tank 41 is increased at this time. The liquid flow rate increases, the impact force on the pipe wall increases, and the pipe wall pressure increases. At this time, multiple long rods 64 will be under pressure, and two steel balls 66 will squeeze the second spring 65 and move out of the clamping connection of the hemispherical groove 63. The long rod 64 rotates and opens on the other side of the long groove 62. At this time, the coolant will quickly cover the cavity formed by the frame 11 and the bottom plate 12, forming an emergency heat dissipation mode, solving the problem that the existing radiator lacks an emergency structure and cannot improve the heat dissipation effect in a short time, reduce the heat source, and thus cause dangers such as fire and explosion;

[0030] Among them, the housing assembly 1 includes a frame 11. Two bottom plates 12 are fixedly installed at the bottom of the frame 11. A hinge 13 is movably hinged at the middle position of the two bottom plates 12. Two fixing blocks 14 are fixedly connected to both the front and rear sides of the frame 11. A top plate 15 is fixedly installed at the top of the frame 11. Multiple reinforcing ribs 16 are provided at the top of the top plate 15;

[0031] The frame 11, the bottom plate 12 and the top plate 15 jointly form a sealed protective shell for the battery cell 22, and the whole can be installed through two groups of fixing blocks 14. When the bottom plate 12 touches and collides, it will bend to both sides along the hinge 13, so that the whole frame 11 can bend along the gap position of the battery cell 22, reducing the irregular force on the battery cell 22 directly when the housing assembly 1 is stressed, thereby reducing the damage risk;

[0032] Among them, the energy storage assembly 2 includes two rubber strips 21. Both rubber strips 21 are fixedly installed on the inner wall of the frame 11. Two battery cells 22 are fixedly connected to the other side of both rubber strips 21. Connection ports 23 are provided at the tops of the two groups of battery cells 22;

[0033] Under normal temperature conditions, the battery cell 22 can discharge through the connection port 23, and there are empty slots between the four battery cells 22;

[0034] Among them, the fixing assembly 3 includes a cross block 31. The cross block 31 is fixedly installed at the middle position of the two groups of battery cells 22. A round rod 32 is installed longitudinally through the cross block 31. Two first springs 33 are elastically connected in the transverse direction of the cross block 31.

Multiple T-shaped rings 34 are fixedly connected to the outer sides of the two groups of battery cells 22;

[0035] When the bottom of the bottom plate 12 is stressed, the energy storage component 2 inside the housing assembly 1 will also complete a slight movement under the support of the fixing component 3. The rubber strips 21 installed on both sides of the battery cell 22 can allow flexible extrusion and displacement for a certain distance. And a plurality of T-shaped rings 34 installed on the other side of the battery cell 22 will, when stressed, squeeze two first springs 33. The first springs 33 will be deformed by the force, but will always exert a supporting force on the battery cell 22 through the plurality of T-shaped rings 34;

[0036] Among them, the circulation component 4 includes a liquid storage and pressurization tank 41, which is fixedly installed on the right side of the frame 11. A liquid inlet pipe 42 and a liquid outlet pipe 43 are fixedly connected to the front side of the liquid storage and pressurization tank 41;

[0037] Under normal temperature conditions, the liquid storage and pressurization tank 41 pressurizes and enters the serpentine copper tube 53 through the liquid inlet pipe 42 and the liquid inlet 54 to dissipate heat from the battery cell 22. In the case of abnormal high temperature, the liquid outlet pressure of the liquid storage and pressurization tank 41 is increased, the liquid flow rate increases, the impact force on the pipe wall increases, and the pipe wall pressure increases, prompting the rotation of the long rod 64 to open;

[0038] Among them, the cooling component 5 includes two fixing strips 51, both of which are fixedly installed on the inner wall of the frame 11. The other sides of the two fixing strips 51 are fixedly connected with a plurality of C-shaped blocks 52. A serpentine copper tube 53 is installed through the middle positions of the plurality of C-shaped blocks 52. The right side of the serpentine copper tube 53 is fixedly connected with a liquid inlet 54, and the left side of the serpentine copper tube 53 is fixedly connected with a liquid outlet 55; The installation positions of the two fixing strips 51 are below the two rubber strips 21. The bottoms of the plurality of C-shaped blocks 52 are fixedly connected to the bottom plate 12. The liquid inlet 54 is fixedly connected to the liquid inlet pipe 42, and the liquid outlet 55 is fixedly connected to the liquid outlet pipe 43;

[0039] The coolant enters the serpentine copper tube 53 from the liquid storage and pressurization tank 41 through the liquid inlet pipe 42. After the heat is replaced, it then circulates back to the liquid storage and pressurization tank 41 through the liquid outlet 55 and the liquid outlet pipe 43 for cooling replacement. In this way, a heat dissipation system is formed.

[0040] Working principle:

[0041] When using the present invention, under normal temperature conditions, the battery cell 22 discharges through the connection port 23. The liquid storage and pressurization tank 41 pressurizes and enters the serpentine copper tube 53 through the liquid inlet pipe 42 and the liquid inlet 54 to dissipate heat from the battery cell 22. When the bottom plate 12 touches and collides during driving, it will bend to both sides along the hinge 13, allowing the entire frame 11 to bend along the gap position of the battery cell 22, reducing the irregular stress on the battery cell 22 directly when the housing assembly 1 is stressed, thereby reducing the risk of damage;

[0042] When the bottom of the bottom plate 12 is stressed, the energy storage component 2 inside the housing assembly 1 will also complete a slight movement under the support of the fixing component 3. The rubber strips 21 installed on both sides of the battery cell 22 can allow flexible extrusion and displacement for a certain distance. And when stressed, multiple T-shaped rings 34 installed on the other side of the battery cell 22 will squeeze two first springs 33. The first springs 33 will be deformed by the force, but will always exert a supporting force on the battery cell 22 through the multiple T-shaped rings 34;

[0043] When the battery cell 22 is damaged by collision or generates a large amount of heat source during overloading, at this time, the liquid outlet pressure of the liquid storage and pressurization tank 41 is increased, the liquid flow rate increases, the impact force on the pipe wall increases, and the pipe wall pressure increases. At this time, multiple long rods 64 will be under pressure, and two steel balls 66 will squeeze the second spring 65 and move out of the clamping connection of the hemispherical groove 63. The long rods 64 will rotate and open on the other side of the long groove 62. At this time, the coolant will quickly cover the cavity formed by the frame 11 and the bottom plate 12 to form an emergency heat dissipation mode.
