Description

Technical Field

[0001] This utility model relates to the field of new energy battery technology, specifically a safety protection box for automotive new energy batteries. Background Technology

[0002] When storing or transporting new energy vehicle batteries, they cannot be directly loaded onto the vehicle. They need to be packed in a battery box before being loaded onto the vehicle for transport. The battery box serves as a safety protection measure to prevent the batteries from being damaged by vibration and impact.

[0003] For example, Chinese patent CN221978127U discloses a safety protection box for automotive new energy batteries, including a battery box with a storage slot inside. The battery box has two symmetrical push rod slots, each with a hydraulic rod fixedly connected to it. Each connecting block is rotatably connected to a rotating shaft located in a slide groove. The rotating shaft is fixedly connected to a roller located in the slide groove. Each fixed sleeve is slidably connected to a positioning frame. An electric push rod is fixedly connected to the upper wall of the storage slot. A first spring is fixedly connected between the pressing plate and the connecting plate. The hydraulic rod can drive the connecting block to move, which, together with the roller, slides in the slide groove, thereby driving the door panel to rotate and open. At the same time, it ensures that the door panel is locked when closed. The new energy battery can be quickly placed on the positioning frame. The electric push rod drives the first spring to press against the upper surface of the new energy battery, thereby fixing the new energy battery and preventing it from falling. The new energy battery plays a shock-absorbing and buffering role through the second buffer spring and the first spring.

[0004] However, in practical applications, the aforementioned safety protection box has a small buffering and shock absorption range, and can only absorb and buffer impacts from the vertical direction. When the side of the protection box is hit, its buffering structure cannot play a buffering and shock absorption role, which makes the battery easily damaged by the impact. Moreover, the aforementioned protection box is not convenient for installing and fixing new energy batteries of different specifications, and its use is quite limited. Utility Model Content

Detailed Implementation

[0026] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0027] Please refer to Figures 1 to 9As shown, a safety protection box for a new energy vehicle battery includes a box body 1, a box cover 2 and a battery body 3. The box cover 2 is movably fitted on the top of the box body 1. Locking components 4 are provided between the bottom sides of the box cover 2 and the box body 1 to fix the box cover 2 to the top of the box body 1. A horizontal movable component 5 is provided at the center of the inner bottom of the box body 1. An inner box 6 is connected to the top of the horizontal movable component 5. Several first telescopic rods 7 are fixedly connected to the four sides of the inner wall of the box body 1. The outer ends of the several first telescopic rods 7 located on the same side are fixedly connected to a stop plate 8. The stop plate 8 is fitted to the outer wall of the inner box 6. A first buffer spring 9 is sleeved on each of the several first telescopic rods 7. Several second telescopic rods 10 are evenly distributed on the inner bottom of the inner box 6. A second buffer spring 11 is sleeved on each of the several second telescopic rods 10. A placement plate 12 is fixedly connected to the top of the several second telescopic rods 10. The battery body 3 is placed on the top of the placement plate 12. A fixing clamping component 13 for fixing the battery body 3 is provided on the placement plate 12. When the protective box is impacted from the side, the inner box 6 and the battery body 3 will move horizontally under the action of the horizontal movable component 5. The first telescopic rod 7 and the first buffer spring 9 are compressed by the abutment plate 8. The first buffer spring 9 absorbs the impact force, thereby cushioning and damping the battery body 3. When encountering bumpy road sections during battery transportation, the second buffer spring 11 absorbs the vertical force, protecting the battery body 3. The first buffer spring 9 and the second buffer spring 11 can provide multi-directional cushioning and shock absorption for the battery body 3, resulting in higher safety. By setting up the horizontal movable component 5, the inner box 6 and the battery body 3 can move horizontally in any direction when the protective box is impacted, and the first buffer spring 9 in the corresponding direction is compressed for cushioning and shock absorption.

[0028] Furthermore, buffer corner protectors 14 are fixedly connected to the four corners at the bottom of the box body 1 and the four corners at the top of the box cover 2. The buffer corner protectors 14 are made of EVA foam. The buffer corner protectors 14 can protect the box body 1 and effectively prevent the corners of the box body 1 from being damaged. The EVA foam material has excellent cushioning performance and shock absorption effect, which can further improve the cushioning protection effect of this protective box.

[0029] Furthermore, the horizontal movable component 5 includes a movable cavity 501 opened inside the bottom end of the box body 1. The movable cavity 501 is disc-shaped, and a movable disc 502 is movably disposed inside the movable cavity 501. A movable circular hole 503 is opened at the inner bottom of the box body 1 and is conductively connected to the movable cavity 501. A connecting post 504 is fixedly connected to the top of the movable disc 502. The connecting post 504 passes through the movable circular hole 503 and is fixedly connected to the outer bottom of the inner box 6. The diameter of the movable disc 502 is larger than the diameter of the movable circular hole 503, so that the movable disc 502 will not detach from the movable cavity 501 through the movable circular hole 503.

[0030] Furthermore, a plurality of first ball bearings 15 are evenly distributed on both the upper and lower sides of the movable disc 502, and a plurality of second ball bearings 16 are evenly distributed on the bottom of the inner box 6. The arrangement of the first ball bearings 15 and the second ball bearings 16 makes the movable disc 502 and the inner box 6 move more smoothly in horizontal motion, which can effectively reduce the friction between the components and improve the service life of the components.

[0031] Furthermore, the fixing clamping assembly 13 includes a first slide groove 1301 formed on the top of the placement plate 12, a first bidirectional lead screw 1302 rotatably connected in the first slide groove 1301, a first motor 1303 connected to one end of the first bidirectional lead screw 1302 on one side of the placement plate 12, two first slide blocks 1304 threadedly connected to the first bidirectional lead screw 1302, a clamping upright plate 1305 integrally formed on the top of each of the two first slide blocks 1304, a second slide groove 1306 formed on opposite sides of the two clamping upright plates 1305, a vertically arranged threaded rod 1307 rotatably connected in the second slide groove 1306, and a clamping upright plate 1306...

A pressure plate 1310 is fixedly connected to the opposite side of the two second slide blocks 1309. A third slide groove 1311 is provided at the bottom of the pressure plate 1310. A second double-acting screw 1312 is rotatably connected in the third slide groove 1311. A third motor 1313 is provided on one side of the pressure plate 1310 and connected to one end of the second double-acting screw 1312. Two third slide blocks 1314 are threadedly connected to the second double-acting screw 1312. A clamping plate 1315 is integrally formed at the bottom of the two third slide blocks 1314. When fixing the battery, the fixing clamping assembly 13 first places the battery body 3 in the center of the top of the placement plate 12. Then, the first motor 1303 is started to drive the first bidirectional lead screw 1302 to rotate, which drives the two first slide blocks 1304 to move the two clamping upright plates 1305 in opposite directions to clamp and fix the left and right sides of the battery body 3 in the middle. Then, the second motor 1308 is started to drive the threaded rod 1307 to rotate, which drives the second slide block 1309 to move the pressure plate 1310 downward to press and fix the top of the battery body 3. Finally, the third motor is started. 1313 drives the second bidirectional lead screw 1312 to rotate, thereby driving the two third slides 1314 to move the two clamping plates 1315 in opposite directions, clamping and fixing the front and rear sides of the central battery body 3. Through the cooperation of the placement plate 12, the clamping upright plate 1305, the pressure plate 1310 and the clamping plate 1315, the front, rear, left, right, upper and lower sides of the battery body 3 are clamped and fixed in all directions. The clamping effect is stable and firm. At the same time, it can clamp and fix battery bodies 3 of different specifications, making the application range of this protective box wider and greatly improving its practicality.

[0032] Furthermore, the first slide groove 1301, the first slide block 1304, the second slide groove 1306, the second slide block 1309, the third slide groove 1311, and the third slide block 1314 are all wedge-shaped. The first slide block 1304 is slidably connected within the first slide groove 1301, the second slide block 1309 is slidably connected within the second slide groove 1306, and the third slide block 1314 is slidably connected within the third slide groove 1311. The wedge-shaped arrangement of the first slide groove 1301, the first slide block 1304, the second slide groove 1306, the second slide block 1309, the third slide groove 1311, and the third slide block 1314 allows each slide block to move stably within its corresponding slide groove, improving the stability of each slide block during movement.

[0033] The working principle and usage procedure of this device are as follows: In use, the battery body 3 is placed in the center of the top of the placement plate 12. Then, the first motor 1303 is started, driving the first bidirectional lead screw 1302 to rotate, which in turn drives the two first slide blocks 1304 to move the two clamping plates 1305 in opposite directions, clamping and fixing the left and right sides of the central battery body 3. Next, the second motor 1308 is started, driving the threaded rod 1307 to rotate, which in turn drives the second slide block 1309 to move the pressure plate 1310 downwards, pressing and fixing the top of the battery body 3. Finally, the third motor 1313 is started, driving the second bidirectional lead screw 1312 to rotate, which in turn drives the two third slide blocks 1314 to move the two clamping plates 1315 in opposite directions, clamping and fixing the front and rear sides of the central battery body 3. This process, achieved through the placement plate 12, clamping plates 1305, and pressure plate... The cooperation of plate 1310 and clamping plate 1315 provides all-around clamping and fixation of the battery body 3 on the front, rear, left, right, top, and bottom sides. After the battery body 3 is fixed, the cover 2 is closed and fixed by the locking component 4. When the side of the protective box is impacted, the inner box 6 and the battery body 3 will move horizontally under the action of the horizontal moving component 5. The first telescopic rod 7 and the first buffer spring 9 are compressed by the abutment plate 8. The first buffer spring 9 absorbs the impact force, thereby buffering and shock-absorbing the battery body 3. When encountering bumpy road sections during battery transportation, the second buffer spring 11 absorbs the vertical force, protecting the battery body 3. The first buffer spring 9 and the second buffer spring 11 can provide multi-directional buffering and shock absorption for the battery body 3, resulting in higher safety. By setting the horizontal moving component 5, the inner box 6 and the battery body 3 can move horizontally in any direction when the protective box is impacted, and the first buffer spring 9 in the corresponding direction is compressed for buffering and shock absorption.
