Technical Field

[0001] The present invention relates to the technical field of new energy vehicles, and more particularly to an aluminum profile housing for a new energy battery. Background Art

[0002] It varies slightly with the types of electric vehicles; in a pure electric vehicle equipped only with a storage battery, the storage battery serves as the sole power source for the vehicle drive system; while in a hybrid electric vehicle equipped with a traditional engine (or fuel cell) and a storage battery, the storage battery can either play the role of the main power source for the vehicle drive system or act as an auxiliary power source. When the vehicle battery is installed in a vehicle, an aluminum profile housing is required;

[0003] In the existing vehicle battery housing, the upper buffer plate, the lower buffer plate, the first transverse buffer plate and the second transverse buffer plate cooperate with the first buffer spring and can not only protect the battery body when the vehicle encounters bumps, sudden braking or sharp turning, but also drive the upper buffer plate, the lower buffer plate, the first transverse buffer plate and the second transverse buffer plate to make a certain displacement by the inertia of the battery body itself, and can use this displacement to accelerate heat dissipation, with the characteristics of simple structure, good protection and good heat dissipation effect, and the characteristics of simple structure and low cost;

[0004] However, when a new energy vehicle is impacted, when the force generated during the impact directly acts on the battery housing, it will cause damage to the battery inside the battery housing and even trigger a fire.

[0035] The left and right sides of the protective shell 2 are provided with second heat dissipation holes 8, the front and rear sides and the top of the protective shell 2 are provided with first heat dissipation holes 7, and a shielding structure is provided near the first heat dissipation holes 7 on the inner wall of the protective shell 2;

[0036] The movable structure includes side plates 6 fastened to the four sides of the protective shell 2 by bolts, and a connecting plate 5 is welded on each side plate 6, and the connecting plate 5 is fixedly connected to the protective plate 4. A base 10 is arranged in the middle of the mounting plate 1, and a first groove 9 is provided on the mounting plate 1 at the peripheral position of the base 10, and the protective shell 2 is movably inserted into the first groove 9. Through grooves 11 are provided on the front and rear sides and the left and right sides of the base 10, and the two through grooves 11 are located on the upper and lower horizontal planes on the base 10.

A guide groove 14 is provided on the side groove wall of the first groove 9, and the movable bar 13 is slidably arranged in the guide groove 14. The horizontal rod 12 movably passes through the protective shell 2, and a first spring 15 is sleeved at both ends of the horizontal rod 12, and the two ends of the first spring 15 are respectively connected to the protective shell 2 and the movable bar 13;

[0037] The buffer structure includes four groups of fixing frames 16 arranged on the upper surface of the mounting plate 1. Each group has two fixing frames 16 corresponding to the positions of the protection plates 4 respectively. A first fixing rod 17 is connected between the inner walls at both ends of the fixing frame 16. A moving block 19 is movably sleeved on the first fixing rod 17. A second spring 18 is connected between the moving block 19 and the inner wall of one end of the fixing frame 16. A curved rod 20 is rotatably connected to the upper surface of the moving block 19. Two groups of mounting blocks 21 are arranged at the lower part of the side surface of the protection plate 4 close to the protection housing 2. One end of the curved rod 20 is rotatably connected to the mounting block 21. A protection structure is arranged in the protection housing 2. When the vehicle is impacted by the outside, the acting force generated during the impact acts on the corresponding protection plate 4. The protection plate 4 moves on the mounting plate 1 in the direction close to the protection housing 2. The curved rod 20 is pushed to move the moving block 19 in the fixing frame 16, squeezing the second spring 18 to compress, so as to share part of the acting force generated during the impact to the mounting plate 1, thus playing a buffering role. At the same time, the protection housing 2 is pushed to move on the mounting plate 1 through the connecting plate 5, so as to increase the distance between the battery body 3 in the protection housing 2 and the impacted part of the vehicle, playing a better protection role for the battery body 3. And during the movement of the protection housing 2, the corresponding first spring 15 will be deformed on the horizontal rod 12 to further play a buffering and protection role.

[0038] See Figures 4-12 , the protection structure includes a protection frame 22 fixedly arranged near the middle of the inner wall of the protection housing 2. The battery body 3 is arranged on the protection frame 22 through a lifting structure. The protection frame 22 is a square frame with a thickness of 6 cm and is made of steel material;

[0039] The lifting structure includes multiple T-shaped rods 24 connected to the lower inner wall of the protection frame 22. A lifting plate 23 is movably sleeved on the T-shaped rods 24. The battery body 3 is fixedly installed on the upper surface of the lifting plate 23. A third spring 25 is sleeved on the T-shaped rods 24. Both ends of the third spring 25 are respectively connected to the lifting plate 23 and the lower inner wall of the protection frame 22. A pulling structure is arranged between the lifting plate 23 and the base 10;

[0040] The pulling structure includes a fixed seat 29 fixedly mounted in the middle of the base 10, an inner groove 30 is provided in the fixed seat 29, an opening 32 is provided in the middle of the groove wall of the inner groove 30, an extrusion wall 31 is provided on the inner wall of the opening 32, and the extrusion wall 31 is an inclined surface. The four sides below the lifting plate 23 are connected to L-shaped plates 26, and a rotating shaft 27 is rotated through one end of the L-shaped plate 26. A rolling sleeve 28 is movably sleeved on the rotating shaft 27, and the rolling sleeve 28 is rollingly set on the extrusion wall 31. When the protective shell 2 moves on the horizontal rod 12, since the base 10 and the fixed seat 29 are fixedly mounted on the mounting plate 1 as a whole, the movement of the protective shell 2 will bring The roller sleeve 28 at one end of the corresponding L-shaped plate 26 rolls on the corresponding extrusion wall 31. Since the extrusion wall 31 is an inclined surface, when the roller sleeve 28 rolls on the extrusion wall 31, it will pull the lifting plate 23 to move downward on the T-shaped rod 24, so that the lifting plate 23 and the battery body 3 can be moved down to the protection frame 22 as a whole, and the protection frame 22 is used to further protect the battery body 3. When the car is not hit and the protective shell 2 is not moved, the lifting plate 23 and the battery body 3 are located directly above the protection frame 22, so that the battery body 3 can be better exposed, thereby better performing the heat dissipation work of the battery body 3.

[0041] See also Figure 1 , Figure 2 , Figure 7 , Figure 8 and Figure 9 The shielding structure includes a shielding plate 34 arranged at the inner wall of the protective shell 2 near the first heat dissipation hole 7, the shielding plate 34 is in an inverted "U" shape, and a heat dissipation groove 33 is opened on the shielding plate 34 at the position of the first heat dissipation hole 7. The shielding plate 34 is arranged on the inner wall of the protective shell 2 through a reset structure;

[0042] The reset structure includes a second groove 35 provided on the inner wall of the protective shell 2 at the position of the baffle plate 34, a second fixing rod 36 is connected between the groove walls on the front and rear sides of the second groove 35, a reciprocating bar 38 is movably sleeved on the second fixing rod 36, and the reciprocating bar 38 is fixedly installed on the baffle plate 34, and fourth springs 37 are sleeved at both ends of the reciprocating bar 38, and the two ends of the fourth spring 37 are respectively connected to the reciprocating bar 38 and the groove wall of the second groove 35. When the car turns, the baffle plate 34 will be driven to shake above the second fixing rod 36 in the left and right directions of the vehicle body, so that the baffle plate 34 blocks the first heat dissipation hole 7 on the protective shell 2, and the second heat dissipation hole 8 is still in an open state, so that the air in the protective shell 2 can generate air convection along the left and right sides of the vehicle body, thereby better taking away the heat generated during the operation of the battery main body 3 in the protective shell 2, thereby improving the heat dissipation effect.

[0043] The implementation principle of the aluminum profile housing for a new energy battery in an embodiment of the present invention is as follows: When the vehicle is impacted by an external force, the force generated during the impact acts on the corresponding protective plate 4. The protective plate 4 moves on the mounting plate 1 in the direction close to the protective housing 2, and through the curved rod 20, it pushes the moving block 19 to move in the fixed frame 16, squeezing the second spring 18 to compress, thereby sharing part of the force generated during the impact to the mounting plate 1, so as to play a buffering role. At the same time, through the connecting plate 5, it pushes the protective housing 2 to move on the mounting plate 1, thereby increasing the distance between the battery body 3 in the protective housing 2 and the impacted part of the vehicle, playing a better protective role for the battery body 3. And during the movement of the protective housing 2, it will drive the corresponding first spring 15 to deform on the horizontal rod 12 to further play a buffering and protective role. Moreover, when the protective housing 2 moves on the horizontal rod 12, it will drive the rolling sleeve 28 at one end of the corresponding L-shaped plate 26 to roll on the corresponding extrusion wall 31, thereby pulling the lifting plate 23 to move downward on the T-shaped rod 24, so that the lifting plate 23 and the battery body 3 can be moved downward into the protective frame 22 as a whole, and the protective frame 22 is used to further protect the battery body 3. When the vehicle is turning, it will drive the baffle 34 to shake in the upper part of the second fixed rod 36 in the left-right direction of the vehicle body, so that the baffle 34 covers the first heat dissipation hole 7 on the protective housing 2. At this time, the second heat dissipation hole 8 is still in an open state, so that the air in the protective housing 2 can generate air convection in the left and right directions of the vehicle body, so as to better take away the heat generated during the operation of the battery body 3 in the protective housing 2 and improve the heat dissipation effect. The structure is simple and the function is practical.

[0044] The above are all the preferred embodiments of the present invention, and the protection scope of the present invention is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
