Description

Technical Field

[0001] The present invention relates to the technical field of new energy batteries, and particularly to a battery pack bracket for a new energy vehicle. Background Art

[0002] New energy vehicles generally refer to electric vehicles, which are vehicles that use an on-vehicle power source and are driven by an electric motor to run on wheels, meeting the requirements of road traffic and safety regulations. During the use of new energy vehicles, the battery needs to continuously discharge. During the battery discharge process, chemical reactions occur inside (such as lithium ions intercalating / extracting from the electrode material), and at the same time, heat is generated due to resistance (Joule heat). If the heat cannot be discharged in time, the battery temperature will rise rapidly.

[0003] Generally, the heat dissipation method of the battery pack is usually to apply a thermal conductive adhesive on the battery pack to transfer the heat to the bracket or the box wall supporting and installing the battery, and then dissipate the heat from the battery bracket or the box wall. However, the heat dissipation efficiency of this method will decrease with the attachment of dust or corrosion on the surface of the battery bracket, reducing the heat dissipation effect. Summary of the Invention

[0023] 3. In the present invention, by making the lengths of the plurality of air guide plates increase in sequence along the air flow direction, the air flow entering the air intake space can be respectively guided by the plurality of air guide plates, so that the gas can enter the interior of the first mounting bracket from different positions at the bottom of the first mounting bracket evenly for heat dissipation, making the heat dissipation effect of the battery pack located inside the first mounting bracket more uniform; in addition, by arranging a pressing plate above the plurality of air guide plates, when the second mounting bracket moves upward, it will squeeze the pressing plate to move downward, making the pressing plate move downward at one end of the upper and lower sliding grooves, and making the plurality of air guide plates rotate synchronously, so as to synchronously control the amount of air entering the interior of the first mounting bracket.

[0024] 4. In the present invention, a sliding cylinder is arranged in the middle of the cooling storage tank, and a sliding rod that slides up and down is arranged inside the sliding cylinder. When the sliding rod slides upward, the through-hole on the sliding rod will connect the communication through-holes on both sides of the sliding cylinder, so that the cooling gas (such as nitrogen) stored inside the cooling storage tank is released and sprayed onto the battery pack, enabling the battery pack to be cooled smoothly. By arranging support plates on both sides of the second mounting frame, when the second mounting frame moves up to a certain position, the support plates can abut against the lower part of the sliding rod. Then, as the second mounting frame continues to slide upward, it will drive the sliding rod to slide upward inside the sliding cylinder, releasing the cooling gas. BRIEF DESCRIPTION OF THE DRAWINGS

The two side walls of the second mounting bracket 2 are in close contact with the two side walls of the first mounting bracket 1. An air intake space 202 is left between the first mounting bracket 1 and the second mounting bracket 2. An air intake through hole 102 for the gas in the air intake space 202 to flow upward is provided at the bottom of the first mounting bracket 1;

[0043] An air guiding assembly 4 is installed inside the air intake space 202 and is used to convey cooling gas into the interior of the first mounting bracket 1. The air guiding assembly 4 includes a plurality of air guiding plates 41 arranged in parallel and obliquely. The air guiding plates 41 are used to introduce the air inside the air intake space 202 into the interior of the first mounting bracket 1 through the air intake through hole 102.

[0044] In the present invention, by arranging the first mounting bracket 1 and the second mounting bracket 2 at intervals, an intake space 202 is formed between the first mounting bracket 1 and the second mounting bracket 2, and a plurality of air guide plates 41 are arranged in the intake space 202. During use, the first mounting bracket 1 is mounted on the vehicle frame, and the second mounting bracket 2 is located below the first mounting bracket 1. During the forward movement of the vehicle, high-speed flowing gas continuously enters the intake space 202, and then enters the interior of the first mounting bracket 1 through the guidance of the air guide plates 41, so as to cool the continuously working battery pack more quickly and avoid too high battery temperature.

[0045] It should be noted that during installation, both sides of the first mounting bracket 1 are respectively connected to the vehicle frame of the automobile, and the intake space 202 is facing the direction of the vehicle head. During the driving of the vehicle, the air flow will enter the interior of the intake space 202 from the opening of the intake space 202; in actual use, an elastic partition net is arranged at the opening of the intake space 202 to prevent sundries from entering the interior of the intake space 202 during driving.

[0046] Further, as Figure 3 and Figure 4 shown, U-shaped mounting plates 15 with openings facing down are respectively arranged on both sides of the first mounting bracket 1, both sides of the second mounting bracket 2 are slidably connected to the U-shaped mounting plates 15, and telescopic members 12 for adjusting the vertical position of the second mounting bracket 2 below the first mounting bracket 1 are fixedly installed on the inner walls of the U-shaped mounting plates 15.

[0047] Among them, by arranging U-shaped mounting plates 15 on both sides of the first mounting bracket 1, the up and down movement of the second mounting bracket 2 can be conveniently guided, and telescopic members 12 are arranged on the mounting plates 15, so that the up and down position of the second mounting bracket 2 can be adjusted as needed during use.

[0048] Further, as Figure 3 and Figure 4 shown, a plurality of first exhaust through holes 103 and a plurality of second exhaust through holes 201 are respectively arranged on the side walls of the first mounting bracket 1 and the second mounting bracket 2. The plurality of first exhaust through holes 103 and the plurality of second exhaust through holes 201 communicate with each other. The upper ends of the inner walls of each of the first exhaust through holes 103 are flush with the second exhaust through holes 201, and the lower ends of the inner walls of each of the first exhaust through holes 103 are lower than the second exhaust through holes 201.

During the use process, when the second mounting bracket 2 moves upward, the second exhaust through holes 201 and the first exhaust through holes 103 will be staggered, which can reduce or close (depending on the rising height of the second mounting bracket 2) the air flow channel between the first exhaust through holes 103 and the second exhaust through holes 201, and the heat dissipation degree can be adjusted appropriately according to the use environment; when the second mounting bracket 2 moves downward from the initial position, the air flow channel at the first exhaust through holes 103 and the second exhaust through holes 201 will not be affected.

[0050] Further, as Figure 5 , Figure 6 and Figure 7 shown, a rotating shaft 411 is arranged at the lower end of the air guide plate 41, and a torsion spring 412 for driving the upper end of the air guide plate 41 to rotate upward is arranged on the rotating shaft 411. The lengths of the plurality of air guide plates 41 increase sequentially along the air flow direction; above the ends of the plurality of air guide plates 41, a pressing plate 42 for adjusting the rotation angle is arranged. Both ends of the pressing plate 42 are fixedly installed with connecting shafts 43. Inside the side wall of the first mounting bracket 1, there are an upper and lower sliding groove 203 and a limiting groove 204 respectively for the two connecting shafts 43 to slide into. The upper and lower sliding groove 203 is located on one side of the longer air guide plate 41, and the upper and lower sliding groove 203 is used to guide one end of the pressing plate 42 to slide up and down. The limiting groove 204 is located on one side of the shorter air guide plate 41, and the limiting groove 204 is used to limit the up and down sliding height of the other end of the pressing plate 42.

[0051] Among them, by making the lengths of the plurality of air guide plates 41 increase sequentially along the air flow direction, the air flow entering the intake space 202 can be respectively guided by the plurality of air guide plates 41, so that the gas can enter the inside of the first mounting bracket 1 from different positions at the bottom of the first mounting bracket 1 evenly for heat dissipation, making the heat dissipation effect of the battery pack inside the first mounting bracket 1 more uniform; in addition, by arranging the pressing plate 42 above the plurality of air guide plates 41, when the second mounting bracket 2 moves upward, it will squeeze the pressing plate 42 to move downward, making one end of the pressing plate 42 located in the upper and lower sliding groove 203 move downward, so that the plurality of air guide plates 41 rotate synchronously, and the air volume entering the inside of the first mounting bracket 1 can be controlled synchronously.

[0052] Further, as Figure 4 , Figure 5 and Figure 6As shown, each row of the air guide plates 41 is respectively installed below each row of the air intake through holes 102. A first sealing plate 16 and a second sealing plate 22 are respectively arranged inside the lower part of the first mounting frame 1 and the second mounting frame 2. The first sealing plate 16 and the second sealing plate 22 are in staggered and close contact with each other, and the first sealing plate 16 and the second sealing plate 22 are located on the side closer to the longer air guide plate 41.

[0053] Among them, by respectively arranging the first sealing plate 16 and the second sealing plate 22 inside the lower part of the first mounting frame 1 and the second mounting frame 2, when the first mounting frame 1 and the second mounting frame 2 are installed with each other, the first sealing plate 16 and the second sealing plate 22 can be in close contact with each other, the tail part of the air intake space 202 can be blocked, sundries can be prevented from entering the air intake space 202 during driving, and the air flow entering the air intake space 202 can be ensured to be squeezed into the first mounting frame 1.

[0054] Further, as Figure 4 and Figure 8 shown, a plurality of cooling storage tanks 3 are fixedly installed inside the mounting plate 15. A connecting pipe 34 passing through the side wall of the first mounting frame 1 is arranged on the side of the cooling storage tank 3. A spray head 13 is arranged on the connecting pipe 34 facing the battery placement position inside the first mounting frame 1. Cooling gas is stored inside the cooling storage tank 3, and the cooling storage tank 3 is used to spray low-temperature gas on the battery when the battery temperature is too high.

[0055] Among them, by arranging the cooling storage tank 3 on the mounting plate 15, when the temperature of the battery pack inside the first mounting frame 1 is too high, by releasing the gas inside the cooling storage tank 3, the battery pack can be successfully cooled, and potential safety hazards caused by overheating of the battery pack can be avoided.

[0056] Further, as Figure 8 and 9 shown, a sliding cylinder 31 is arranged in the middle of the cooling storage tank 3. Communication through holes 3101 are arranged through both sides of the sliding cylinder 31. One end of the connecting pipe 34 is communicated with the sliding cylinder 31. A sliding rod 32 is slidably installed inside the sliding cylinder 31. An elastic member 33 for driving the sliding rod 32 to move downward is arranged inside the sliding cylinder 31. A through hole is arranged on the sliding rod 32. When the sliding rod 32 slides upward, the through hole is communicated with the communication through hole 3101 to release the cooling gas; Support plates 21 are respectively arranged on both sides of the second mounting frame 2, and the support plates 21 are used to drive the sliding rod 32 to move upward during the upward movement of the second mounting frame 2.

[0057] Among them, by arranging a sliding cylinder 31 in the middle of the cooling storage tank 3 and arranging a sliding rod 32 that slides up and down inside the sliding cylinder 31, when the sliding rod 32 slides upward, the through holes on the sliding rod 32 will connect the communication through holes 3101 on both sides of the sliding cylinder 31, so that the cooling gas (such as nitrogen) stored inside the cooling storage tank 3 is released and sprayed onto the battery pack, and the battery pack can be cooled smoothly; by arranging support plates 21 on both sides of the second mounting bracket 2, when the second mounting bracket 2 moves up to a certain position, the support plate 21 can abut against the lower part of the sliding rod 32, and then as the second mounting bracket 2 continues to slide upward, it will drive the sliding rod 32 to slide upward inside the sliding cylinder 31, releasing the cooling gas.

[0058] It should be noted that in the initial state, there is a gap between the bottom of the sliding rod 32 and the support plate 21 to allow the support plate 21 to move up and down for a short distance.
