DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0029] See also Figure 1-Figure 5As shown, the utility model is a device for quickly separating a battery box from a vehicle body, comprising a vehicle body assembly part 1, a warning light 2 is installed on one side of the vehicle body assembly part 1, a first installation shaft 3 is arranged on the side of the two ends of the vehicle body assembly part 1 away from the warning light 2, a first worm gear 4 is installed at the middle position of the outer side of the first installation shaft 3, and a protective bin 5 is installed on the outer side of the first installation shaft 3, a battery box body 6 is arranged inside the protective bin 5, and pulleys 7 are installed at the four corners of the bottom of the battery box body 6, limiting grooves 11 are provided at both ends of the protective bin 5 close to the warning light 2, an installation groove 21 is provided on the top of the vehicle body assembly part 1 close to the warning light 2, a pressing block 8 is installed at the bottom of the vehicle body assembly part 1, and the pressing block 8 is kept in close contact with the battery box body 6, and the pressing block 8 can be made of hard rubber, so that after the assembly is completed, the pressing block 8 can cooperate with the protective bin 5 to fully press the battery box body 6 to ensure its stability in the protective bin 5;

[0030] like Figure 2 As shown, a temperature detector 9 is installed on the top of the protective compartment 5 on the side away from the warning light 2, and a steel wire rope 10 is installed on the bottom of the protective compartment 5 on the side close to the temperature detector 9, and the end of the steel wire rope 10 away from the protective compartment 5 is connected to the battery box body 6, and the temperature detector 9 is electrically connected to the instrument part in the cab. The staff can understand the temperature in the protective compartment 5 through the temperature detector 9, and then judge whether it is in an emergency situation of overheating. The steel wire rope 10 can limit the distance that the battery box body 6 is separated in an emergency situation, thereby preventing the battery box body 6 from sliding without restriction and causing excessive impact on the surrounding area;

[0031] like Figure 2 and Figure 3 As shown, a movable mechanism for closing the protective chamber 5 is provided on the vehicle body assembly part 1, and the movable mechanism includes a second mounting shaft 12, and the second mounting shaft 12 is arranged on the side close to the warning light 2 at both ends inside the vehicle body assembly part 1, a second worm gear 13 is installed at the middle position of the outer side of the second mounting shaft 12, and a closing plate 14 is installed on the outer side of the second mounting shaft 12, and support blocks 15 are installed at both ends of the closing plate 14 away from the warning light 2, and the support blocks 15 extend to the inside of the limiting groove 11, so that in a normal state, the closing plate 14 can close the protective chamber 5, and at the same time, the support blocks 15 are inserted into the limiting groove 11 to cooperate with the battery box body 6 to play a supporting role;

[0032] like Figure 2 , Figure 3 and Figure 4As shown, a driving mechanism for driving the movable mechanism and the protective chamber 5 to rotate is provided on the vehicle body assembly part 1, and the driving mechanism includes a servo motor 16, which is installed on a side of the vehicle body assembly part 1 away from the warning light 2, and the output end of the servo motor 16 is connected to a threaded rod 17, and a first worm 18 is installed on the outer side of the end of the threaded rod 17 away from the warning light 2, and a second worm 19 is installed on the outer side of the end of the threaded rod 17 close to the warning light 2, and an extrusion block 20 is sleeved on the outer side of the end of the threaded rod 17 close to the installation groove 21, and the central axis of the first worm 18 coincides with the central axis of the threaded rod 17, and the first worm 18 is meshed with the first worm wheel 4, and the second worm 19 is meshed with the second worm wheel 13, and the transmission direction of the second worm 19 is the same as that of the first worm 18. The worm 18 rotates in the opposite direction, so that when the servo motor 16 drives the threaded rod 17 and the first worm 18 and the second worm 19 thereon to rotate forward, the protective chamber 5 can rotate counterclockwise, and the closing plate 14 can rotate clockwise, so that the closing plate 14 releases the sealing of the protective chamber 5, and the protective chamber 5 tilts to a certain extent, so that the battery box body 6 can slide out of the protective chamber 5. In the further application process, the rotation amplitude of the first installation shaft 3 driven by the first worm 18 can be smaller than the rotation amplitude of the second installation shaft 12 driven by the second worm 19. At the same time, the gap between the closing plate 14 and the protective chamber 5 and the vehicle body assembly part 1 can be closed by an elastic bellows, and the servo motor 16 and the temperature detector 9 are powered by an independent backup power supply; Example 2

[0033] like Figure 2 and Figure 3 As shown, the squeezing block 20 is threadedly connected to the threaded rod 17, and the squeezing block 20 is slidably connected to the vehicle body assembly part 1. Both sides of the top of the squeezing block 20 are arranged with arc edges. A squeezing button 22 is arranged inside the mounting groove 21, and a spring 23 is connected between the squeezing button 22 and the vehicle body assembly part 1. The squeezing button 22 is electrically connected to the warning light 2, so that when the threaded rod 17 rotates forward, the squeezing block 20 can move in the direction close to the squeezing button 22, and squeeze the squeezing button 22 upward through the arc edge part. At the same time, the elasticity of the spring 23 is greater than the pressure required for pressing the squeezing button 22 itself, so that when the threaded rod 17 rotates initially, the squeezing button 22 can be squeezed, and the warning light 2 lights up, thereby prompting surrounding vehicles to avoid. At the same time, the warning light 2 can be further equipped with a buzzer for a higher intensity prompt, and the squeezing button 22 and the warning light 2 are both powered by an independent backup power supply;

[0034] The working principle of the utility model is as follows: during the assembly process, the servo motor 16 is controlled to drive the threaded rod 17 to rotate forward, and the first worm 18 is meshed with the first worm wheel 4, and the second worm 19 is meshed with the second worm wheel 13, so that the protective chamber 5 can be rotated counterclockwise to tilt, and the closing plate 14 can be rotated clockwise to release the closure of the protective chamber 5, until the height of the opening of the protective chamber 5 is sufficient for the battery box body 6 to pass through. At this time, after the staff completes the connection of the wire rope 10, they can directly slide the battery box body 6 into the interior of the protective chamber 5 through the pulley 7, and then control the servo motor 16 to rotate in the opposite direction until the protective chamber 5 is tilted. The protective bin 5 returns to a horizontal state, and the closing plate 14 closes the protective bin 5. At the same time, in the initial stage of the operation, the battery box body 6 can be pushed against the inside of the protective bin 5 by the push rod. The closing plate 14 can limit the sliding out of the battery box body 6 after a small rotation. At the same time, after the assembly is completed, the support block 15 on the closing plate 14 will be inserted into the corresponding limiting groove 11 to assist in supporting the protective bin 5 and the battery box body 6. At the same time, since the first worm gear 4 cannot drive the first worm 18 to rotate, and the second worm gear 13 cannot drive the second worm 19 to rotate, no load pressure will be caused to the servo motor 16 after the assembly is completed;

[0035] When the driver learns through the temperature detector 9 and the instrument part that overheating has occurred in the protection chamber 5, the vehicle can be controlled to move toward the emergency lane and other parts, and then the servo motor 16 is controlled to drive the threaded rod 17 to rotate forward. As mentioned above, the protection chamber 5 can begin to tilt at this time, and the closing plate 14 begins to release the closure of the protection chamber 5. At the same time, through the threaded connection between the extrusion block 20 and the threaded rod 17, the sliding connection between the extrusion block 20 and the vehicle body assembly part 1, the extrusion block 20 will move toward the direction close to the extrusion button 22 and squeeze the extrusion button 22 toward the inside of the mounting groove 21 through the arc edge, so that pressing the extrusion button 22 does not affect the subsequent movement of the extrusion block 20 at the same time, and the warning light 2 is on at any time to warn the surrounding personnel and vehicles. Subsequently, the threaded rod 17 continues to rotate until the closing plate 14 completely releases the closure of the protection chamber 5. At this time, under the action of gravity, the battery box body 6 slides out of the protection chamber 5 through the pulley 7 until it is restricted by the wire rope 10, thereby ensuring the safety of the driver, surrounding personnel and vehicles.

[0036] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
