Description

Technical Field

[0001] The present invention belongs to the technical field of battery boxes, and in particular relates to a battery box for a new energy vehicle. Background Art

[0002] The battery box of new energy vehicles is an important part of the power system of new energy vehicles. It can provide impact protection for the battery cells installed inside. The existing new energy battery box can accommodate one or more battery packs. The batteries are generally placed directly inside the battery box for installation and fixation. Over time, the batteries are affected by factors such as long-term vibration of the car, which will cause the batteries to not only be easily hit and vibrate during driving, but also generate noise due to the gaps between the batteries. Moreover, if the battery box is damaged or the battery cell components inside are pierced by sharp objects during driving, the damaged battery is likely to cause fire first, and then pass the fire to the remaining battery packs, thereby expanding the fire, which will shorten the escape time of the driver and passengers. Therefore, a mechanism is needed to partition and isolate the battery box to reduce the linkage damage of the battery pack that has caught fire. Summary of the invention

[0003] The purpose of the present invention is to provide a new energy vehicle battery box to solve the problems raised in the above background technology.

A plurality of inclined rods are fixedly connected inside the four rectangular frames, and a second spring is elastically connected between the plurality of inclined rods.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. The present invention is equipped with a partition component. When the battery box is damaged or the battery cell component inside it is pierced by a sharp object, the first shell and the second shell at the position of the damaged battery pack are driven by the rotating block to rotate to the same axis, and the fixing component cancels the fixation of the battery pack.

[0014] 2. The present invention is equipped with a shock-absorbing component and a protection component. Four circular shafts, two long strips and two short strips together form a movable rectangular structure at the bottom of the bottom shell. When the second telescopic rod is subjected to lateral and longitudinal forces, it will shrink its stroke on the long strip and drive the two short strips to rotate on the top of the long strip to form a parallelogram. The first telescopic rod will shorten or increase its stroke according to the direction of force to offset the lateral impact force received, and the longitudinal force will be transmitted to the rectangular plate through the first U-shaped block and the second U-shaped block when the first telescopic rod is subjected to force. After the force is offset, the first telescopic rod will reset under the action of the first spring, thereby protecting the outer shell from being touched during driving.

[0015] 3. The present invention is equipped with a fixed component and a rotating block, so that the first shell and the second shell can rotate and squeeze the battery pack, and the battery pack will be close to the inner wall of the frame in the reinforcement groove and squeezed to the fixed component. Multiple second springs that are squeezed into an arc by the inclined rod will squeeze the other side of the battery pack, forming a laterally shock-absorbing battery pack structure in the shell composed of the bottom shell and the frame to offset the problem of multiple battery pack components being prone to collision and vibration during long-term driving, which will generate noise.

[0033] Working principle:

[0034] When using the automatic separation battery box, the entire battery box is installed through the fan-shaped blocks 23, the fixing plate 21 and the circular hole bars 24 installed on the four sides of the shell 1. The multiple annular blocks 22 in the fixing plate 21 play a role in firmly fixing the shell 1 horizontally and vertically. The multiple battery packs 51 can be powered through the discharge interface 52, and the multiple battery packs 51 can be charged through the charging interface 53. The rotating block 73 is started, so that the first shell 74 and the second shell 75 can rotate and squeeze the battery pack 51, and the battery pack 51 will be close to the inner wall of the frame 13 in the reinforcement groove 12 and squeezed to the fixing component 6. The multiple second springs 63 squeezed into an arc by the inclined rod 62 will squeeze the other side of the battery pack 51, and a lateral shock-absorbing battery pack structure is formed in the shell composed of the bottom shell 11 and the frame 13 to offset the problem of multiple battery pack components being easily hit and generating vibration and noise during driving;

[0035] When driving, the connecting assembly 2 installed at the bottom of the bottom shell 11 will protect the outer shell 1. The four circular shafts 36, the two long strips 41 and the two short strips 42 together form a movable rectangular structure at the bottom of the bottom shell 11. When the second telescopic rod 43 is subjected to lateral and longitudinal forces, it will shrink the stroke on the long strip 41 and drive the two short strips 42 to rotate on the top of the long strip 41 to form a parallelogram. The first telescopic rod 33 will shorten or increase the stroke according to the force direction to offset the lateral impact force received, and the longitudinal force will be transmitted to the rectangular plate 31 through the first U-shaped block 32 and the second U-shaped block 35 when the first telescopic rod 33 is subjected to force. After the force is offset, the first telescopic rod 33 will be reset under the action of the first spring 34, and the long strip 41 and the short strip 42 will return to a rectangle.

[0036] When the battery case is damaged or the battery cell assembly 5 inside it is pierced by a sharp object, the first shell 74 and the second shell 75 at the position of the damaged battery pack 51 are driven by the rotating block 73 to rotate to the same axis, and the fixing assembly 6 cancels the fixation of the battery pack 51. At this time, the rotating block 73 moves on the screw rod 72, so that the two opposite first shells 74 and the second shells 75 are close to each other. After the sub-buckle 78 is inserted into the female buckle 77, the two opposite first shells 74 and the second shells 75 are moved to both sides by the screw rod 72, and the fireproof roll strip 76 inside the first shell 74 will be pulled out to form an isolation area together with the frame 13 and the fireproof strip 71.
