Abstract
Description
Technical Field
[0001] This utility model relates to the field of control boxes, and more particularly to a drive control box for explosion-proof lithium-ion transport vehicles. Background Technology
[0002] Explosion-proof lithium-ion transport vehicles have been widely used in many scenarios with stringent safety requirements, such as chemical, petroleum, and mining industries, due to their advantages of high efficiency, environmental protection, and explosion-proof characteristics. Among them, the drive control box, as the key carrier of the drive control system, plays a vital role in ensuring the normal operation of the entire system due to the rationality of its structural design.
[0003] However, in traditional explosion-proof rubber-wheeled vehicles, the electrical control box is rigidly fixed to the frame with bolts. This design requires the removal of the entire vehicle's protective plate during maintenance, which is extremely inconvenient. At the same time, this fixing method has insufficient impact resistance. When the vehicle is driving on bumpy roads, vibrations will be directly transmitted to the circuit boards inside the control box through the rigid connection. Over time, this can easily lead to cracking of the solder joints, leaving the control box without effective protection when facing vibration and impact. Utility Model Content
[0004] To overcome the problems of traditional explosion-proof rubber-wheeled vehicles where the electrical control box is rigidly fixed to the frame with bolts, making maintenance inconvenient and impact resistance insufficient, vibration can easily cause the circuit board solder joints to crack, and there is a lack of effective protection.
[0005] The technical solution of this utility model is as follows: an explosion-proof lithium-ion transport vehicle drive control box, including an L-shaped bracket installed on the transport vehicle. A shock absorber connected to the transport vehicle is installed at the lower horizontal end of the bracket. The control box body is installed at the upper end of the bracket via a sliding mechanism. A protective shell is installed at the rear end of the bracket. An electric push rod is installed on the end face of the protective shell. A clamping module for fixing the control box body is installed at the power output end of the electric push rod. The clamping module is opened or closed by the electric push rod. A guide mechanism connected to the clamping module is installed at the upper horizontal end of the bracket. The clamping module is guided to move by the guide mechanism. The clamping module includes a transmission unit connected to the power output end of the electric push rod and a clamping unit connected to the transmission unit. The transmission unit drives the clamping unit to clamp or release the control box body.
[0006] Preferably, the transmission unit includes a transmission plate disposed on the power output end of the electric push rod, a transmission block one disposed on the upper end of the transmission plate, a transmission block two disposed on the lower end of the transmission plate, and a connecting rod rotatably connected to both the transmission block one and the transmission block two, and a connecting block rotatably connected to the connecting rod.

The surfaces of the first clamping plate and the second clamping plate are arrayed with floppy disks, and a reinforcing rod is provided between the first clamping plate and the second clamping plate.
[0008] Preferably, the sliding mechanism includes a convex rail integrally mounted on the horizontal part of the bracket, and a sliding groove adapted to the convex rail is provided at the lower end of the control box body, with the convex rail and the sliding groove being slidably connected.
[0009] Preferably, the guiding mechanism includes a slide rail mounted on the horizontal part of the frame, a slider mounted on the slide rail, and the end face of the slider being connected to the lower end of the clamping plate.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0021] Please see Figure 1 - Figure 5This utility model provides an embodiment of an explosion-proof lithium-ion transport vehicle drive control box, including an L-shaped bracket 1 mounted on the transport vehicle. A shock absorber 2 connected to the transport vehicle is mounted at the lower horizontal end of the bracket 1. A control box body 3 is mounted at the upper end of the bracket 1 via a sliding mechanism. A protective shell 4 is mounted at the rear end of the bracket 1. An electric push rod 5 is mounted on the end face of the protective shell 4. A clamping module for fixing the control box body 3 is mounted at the power output end of the electric push rod 5. The clamping module is opened or closed by the electric push rod 5. A guide mechanism connected to the clamping module is mounted at the upper horizontal end of the bracket 1. The clamping module is guided to move by the guide mechanism.The clamping module includes a transmission unit connected to the power output end of the electric push rod 5 and a clamping unit connected to the transmission unit. The transmission unit drives the clamping unit to clamp or release the control box body 3. The L-shaped bracket 1 serves as the main supporting structure for the entire drive control box. The shock absorber 2 is located at the lower horizontal part of the bracket 1 and connected to the transport vehicle. During the transport vehicle's operation, various vibrations and impacts will occur due to the complex and changing road conditions. The shock absorber 2 utilizes the synergistic effect of its internal elastic elements (such as springs) and damping elements (such as hydraulic dampers) to absorb and buffer the vibration energy transmitted from the transport vehicle. When encountering bumpy roads, the elastic elements... Elastic deformation occurs, converting vibration energy into stored elastic potential energy. Simultaneously, the damping element dissipates this energy by generating a damping force opposite to the vibration direction, effectively reducing damage to the internal electronic components of the drive control box and ensuring stable operation of the control box body 3. The sliding mechanism allows for easy movement of the control box body 3 during maintenance and repair. The control box body 3 integrates various electronic control components, such as circuit boards, controllers, and sensors. These components work together to achieve precise control of the explosion-proof lithium-ion transport vehicle's drive system, ensuring safe, stable, and efficient operation of the transport vehicle. The electric actuator 5 serves as the power source for the clamping module. It consists of a motor, a reduction mechanism, and a lead screw and nut assembly. When the motor is powered on, the reduction mechanism reduces the output speed of the high-speed rotating motor while increasing the output torque, which in turn drives the lead screw to rotate. The rotation of the lead screw causes the mating nut to move linearly along its axis, thus achieving the extension and retraction of the electric actuator 5. By controlling the forward and reverse rotation of the motor, the extension and retraction direction and stroke of the electric actuator 5 can be precisely controlled, providing a stable power output to the clamping module and enabling its opening and closing operations. The transmission unit converts the linear motion of the electric actuator 5 into… The clamping or releasing action required by the clamping unit is transformed into the clamping action. When the transmission unit drives the clamping unit to move, it applies a clamping force to the control box body 3, fixing it to the bracket 1. When it is necessary to release the control box body 3, the clamping units move away from each other under the action of the transmission unit, releasing the clamping of the control box body 3, allowing the control box body 3 to move through the sliding mechanism. The guide mechanism is used to provide precise guidance for the movement of the clamping module. When the electric push rod 5 drives the clamping module to move, the clamping module moves along the direction set by the guide mechanism, ensuring that the clamping module maintains a stable movement trajectory during opening, closing, or slamming without deviation or shaking.
[0022] Please see Figure 3In this embodiment, the transmission unit includes a transmission plate 6 disposed on the power output end of the electric push rod 5. A transmission block 7 is disposed on the upper end of the transmission plate 6, and a transmission block 8 is disposed on the lower end of the transmission plate 6. A connecting rod 9 is rotatably connected to both the transmission block 7 and the transmission block 8, and a connecting block 10 is rotatably connected to the connecting rod 9. The clamping unit includes a clamping plate 11 and a clamping plate 12 connected to the connecting block 10. Floppy disks 13 are arrayed on the surface of the clamping plate 11 and the clamping plate 12. A reinforcing rod 14 is disposed between the clamping plate 11 and the clamping plate 12. The guiding mechanism includes a guide plate disposed on the horizontal part of the frame. The slide rail 17 has a slider 18 mounted on it. The end face of the slider 18 is connected to the lower end of the clamping plate 12. The transmission plate 6 serves as a connecting component between the transmission unit and the power output end of the electric push rod 5. The transmission plate 6 acts as a bridge for power transmission. When the power output end of the electric push rod 5 extends or retracts, it directly drives the transmission plate 6 to produce a corresponding displacement. When the transmission plate 6 moves with the electric push rod 5, the transmission block 7 and the transmission block 8 move synchronously, converting the linear motion of the electric push rod 5 into its own movement. When the transmission block 7 and the transmission block 8 move under the drive of the transmission plate 6, the connecting rod 9 transmits the power... The linear motion of the moving block is converted into its own oscillating motion, and then, through rotational connection with the connecting block 10, the oscillating motion is further converted into linear clamping or releasing motion of the connecting block 10 and the clamping unit. This conversion of motion forms allows the linear motion of the electric push rod 5 to be effectively converted into the clamping action required by the clamping unit. Driven by the connecting block 10, clamping plates 11 and 12 can move simultaneously to achieve stable clamping or releasing of the control box body 3. The floppy disks 13 arranged in an array on their surface have multiple functions. On the one hand, the floppy disks 13 increase the clamping distance between the clamping plates and the control box body 3. The friction between the plates improves the stability of the clamping and prevents the control box body 3 from shifting due to vibration during transportation. On the other hand, the floppy disk 13 acts as a buffer, absorbing the impact force generated during clamping and preventing the clamping plates from scratching or damaging the surface of the control box body 3. The reinforcing rod 14 is set between the first clamping plate 11 and the second clamping plate 12, which enhances the overall structural strength and stability of the clamping unit. At the same time, the reinforcing rod 14 can also improve the rigidity of the clamping unit, ensuring that the first clamping plate 11 and the second clamping plate 12 remain parallel and stable during clamping, thus improving the clamping effect.
[0023] Please see Figure 2 , Figure 4 and Figure 5In this embodiment, the sliding mechanism includes a convex rail 15 integrally mounted on the horizontal part of the bracket 1. A groove 16 adapted to the convex rail 15 is provided at the lower end of the control box body 3, and the convex rail 15 and the groove 16 are slidably connected. A sliding plate 19 is provided on the vertical part of the bracket 1. Through grooves 20 adapted to the sliding plate 19 are provided at the upper end of transmission block 1 7 and the lower end of transmission block 2 8, and the sliding plate 19 and the through grooves 20 are slidably connected. Adaptive magnets are provided in both the convex rail 15 and the groove 16, and the convex rail 15 and the groove 16 are magnetically connected. The sliding rail 17 is mounted on the horizontal part of the bracket 1, providing a stable track for the movement of the slider 18. When the clamping module moves under the drive of the transmission unit, the slider 18 slides linearly along the sliding rail 17. This design provides precise control over the movement of the clamping module. The guide rail 15 and the slide rail 16 prevent the clamping module from shifting or shaking during movement. The design of the guide rail 15 and the slide rail 16 allows the control box body 3 to slide freely on the guide rail 15 via the slide rail 16, realizing convenient movement of the control box body 3 on the bracket 1. When it is necessary to maintain, repair or adjust the position of the control box body 3, simply push the control box body 3 to slide it to the designated position along the guide rail 15. In addition, the two are magnetically connected. This magnetic connection method not only ensures the stability of the control box body 3 in the fixed state, but also facilitates its movement operation when needed, achieving a balance between stability and convenience. The slide plate 19 provides additional guidance and support for the movement of transmission block 7 and transmission block 8, ensuring that the power can be accurately transmitted to the clamping unit.
[0024] Working principle: During the journey, due to the complex and ever-changing road conditions, the transport vehicle will generate various vibrations and impacts. At this time, the shock absorber 2 uses the synergistic effect of internal elastic elements (such as springs) and damping elements (such as hydraulic dampers) to absorb and buffer the vibration energy transmitted from the transport vehicle, effectively reducing the damage of vibration to the electronic components inside the drive control box and ensuring the stable operation of the control box body 3.
[0025] When maintenance, repair, or position adjustment of the control box body 3 is required, the operator starts the electric push rod 5. The transmission plate 6 moves with the electric push rod 5, driving the transmission block 1 7 and transmission block 2 8 to move synchronously. The connecting rod 9 converts the linear motion of the transmission block into its own swing motion. Then, through the rotational connection with the connecting block 10, the swing motion is further converted into the linear clamping or releasing motion of the connecting block 10 and the clamping unit. Under the drive of the connecting block 10, the clamping plate 1 11 and clamping plate 2 12 move simultaneously to release the control box body 3.
[0026] At this time, the control box body 3 can be moved by the sliding mechanism. At the same time, the convex rail 15 and the slide groove 16 are both equipped with matching magnets. The magnetic connection not only ensures the stability of the control box body 3 in the fixed state, but also facilitates its movement operation when needed.
[0027] After maintenance, repair or adjustment is completed, the operator restarts the electric push rod 5 to make it move in the opposite direction. The transmission unit converts the linear motion of the electric push rod 5 into the clamping action required by the clamping unit. The clamping plates 11 and 12 move simultaneously to stably clamp the control box body 3 onto the bracket 1. At this time, the control box body 3 returns to a fixed state, and the explosion-proof lithium-ion transport vehicle can continue to drive.
[0028] Through the above steps, by using L-shaped bracket 1 and shock absorber 2 to protect electronic components, and sliding mechanism and electric push rod 5 to drive clamping module to work, it is convenient for staff to maintain and repair. It solves the problems of traditional explosion-proof rubber-wheeled vehicle electrical control box and frame bolt rigid fixation, inconvenient maintenance and insufficient impact resistance, vibration can easily cause circuit board solder joints to crack, and lack of effective protection.
