Description

Technical Field

[0001] This invention relates to the field of new energy trailer technology, specifically an electric drive device for a new energy trailer. Background Technology

[0002] A traditional trailer is a vehicle towed by a truck but without its own power drive. It consists of a truck and one or more trailers, relying on the power provided by the tractor unit. The truck and the towing truck are the driving sections of the truck train, called the tractor unit, and the driven sections towed by the tractor unit are called trailers. It is an important type of vehicle for road transport. Using truck trains is the most effective and simplest way to improve economic efficiency and can conveniently realize segmented transport.

[0003] Existing technology has several drawbacks: current trailers rely entirely on the tractor for power, which consumes a lot of fuel, has a short range, and is inconvenient to operate in complex road conditions; when the road conditions are poor, such as rain, icy roads, or uneven roads, the trailer's center of gravity is prone to shift, which may even lead to rollover, posing a safety hazard; when unloading cargo from the trailer, the goods need to be manually moved out of the cargo box, which is labor-intensive and inefficient. Summary of the Invention

[0004] The purpose of this invention is to provide an electric drive device for new energy trailers to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: The electric drive device for the new energy trailer includes a trailer frame, an electric drive box is installed below the trailer frame, a tilt sensor is installed below the electric drive box, a battery panel, a drive motor, a mechanical transmission device, a regeneration device, and a controller are installed in the electric drive box, a wheel is installed on one side of the mechanical transmission device, a hydraulic cylinder and an anti-rollover device are installed below the trailer frame, a support block is installed on the cylinder rod of the hydraulic cylinder, a partition is installed above the trailer frame, an automatic unloading device is installed on the partition, and the battery panel, drive motor, regeneration device, tilt sensor, and hydraulic cylinder are connected to the controller. When the trailer is at risk of tipping over, the tilt sensor under the electric drive box detects the trailer tilting, and the controller activates the anti-tipping device to adjust the trailer's center of gravity, shifting it towards the tilted side. Simultaneously, it supports the tilted side to prevent the trailer from tipping over. When unloading is required, the controller extends the hydraulic cylinder rod, which moves the support block towards the ground until it touches the ground. The unloading door of the trailer is then manually opened, and the controller is manually activated to start the automatic unloading device. The trailer bed automatically tilts until it reaches the designated angle for unloading. After unloading is complete, the automatic unloading device is activated, causing the trailer bed to rotate back to its initial position, and the unloading door is manually closed.

[0006] The anti-rollover device includes a center of gravity adjustment device, a first support device, and a second support device. The center of gravity adjustment device is installed below the trailer frame. A first gear is installed at one end of the center of gravity adjustment device. A drive belt meshes with the outer side of the first gear. A second gear and a third gear mesh with the inner wall of the drive belt. The second gear rotates on the first support device, and the third gear rotates on the second support device. The first support device is installed on one side of the electric drive box, and the second support device is installed on the other side of the electric drive box. When the tilt sensor detects that the trailer is tilting towards the first support device, the controller activates the center of gravity adjustment device, increasing the weight on the second support device side of the trailer, shifting the center of gravity towards the second support device. Simultaneously, the center of gravity adjustment device drives the first gear to rotate, which in turn drives the drive belt, which in turn drives the second and third gears. The second gear then activates the first support device, placing it on the ground, while the third gear moves the second support device away from the ground.

[0007] The center of gravity adjustment device includes a mounting plate and a first rotating shaft. A first gear is mounted on the first rotating shaft. The mounting plate is installed below the trailer frame. An H-shaped plate and a fixed plate are mounted on one side of the mounting plate. A first motor is mounted on one side of the fixed plate. A fourth gear is mounted on the output shaft of the first motor. The first rotating shaft is rotatably connected to the fixed plate. A fifth gear and a sixth gear are mounted on the first rotating shaft. The fifth gear meshes with the fourth gear. A movable plate is slidably connected to the H-shaped plate. A rack is connected to one side of the movable plate. The rack meshes with the sixth gear. A counterweight is installed between the two movable plates. The first motor is connected to a controller. When the tilt sensor detects that the trailer is tilted towards the first support device, the controller starts the first motor. The output shaft of the first motor drives the fourth gear to rotate, the fourth gear drives the fifth gear to rotate, the fifth gear drives the first shaft to rotate, the first shaft drives the sixth gear to rotate, and the sixth gear drives the rack to slide towards the second support device. The rack drives the moving plate to slide, making the weight on the second support device side greater than the weight on the first support device side. When the tilt sensor detects that the trailer is tilted towards the second support device, the controller reverses the first motor and repeats the above steps, making the weight on the first support device side greater than the weight on the second support device side.

[0008] The first support device includes a side plate, which is installed on one side of the electric drive box. A rotating column is installed on the side plate, and the second gear rotates on the rotating column. A short rod is installed on the rotating column, and a long rod is rotatably connected to one side of the short rod. A T-shaped plate is rotatably connected to one side of the long rod. A slide rail is connected to one side of the side plate, and the T-shaped plate slides in the slide rail. A caster wheel is installed below the T-shaped plate. The first support device and the second support device have the same structure. When the tilt sensor detects that the trailer is tilted towards the first support device, the second gear drives the rotating column to rotate. The rotating column drives the short rod to rotate towards the ground. The short rod drives the long rod to rotate. The long rod drives the T-shaped plate to slide towards the ground in the slide rail. The T-shaped plate drives the casters to move towards the ground until they touch the ground. The third gear drives the rotating column of the second support device to rotate. The rotating column drives the short rod to rotate away from the ground, so that the casters of the second support device are away from the ground. When the tilt sensor detects that the trailer is tilted towards the second support device, the above steps are repeated, so that the casters of the second support device touch the ground and the casters of the first support device are away from the ground.

[0009] The automatic unloading device includes a load-bearing block connected to one side of a partition. A lifting device and a stabilizing device are mounted above the partition, rotatably connected to each other. A cylinder is mounted on the load-bearing block, and a horizontal plate is rotatably connected to the cylinder. A trailer is mounted on the horizontal plate, and a loading door is installed on one side of the trailer. The lifting device is rotatably connected to the horizontal plate. When the trailer is unloading, the operator manually opens the loading door, and the controller activates the lifting and stabilizing devices, causing the trailer to rotate around the cylinder until a designated angle is reached, at which point the trailer unloads from the loading door. When unloading is complete, the controller activates the lifting and stabilizing devices again, causing the trailer to rotate back to its initial position around the cylinder, and the operator manually closes the loading door.

[0010] The lifting device includes a second motor and a track. The second motor and the track are mounted on a partition. A lead screw is mounted on the output shaft of the second motor. A nut seat is slidably connected to the lead screw. A first bevel gear is mounted on the lead screw and meshes with a stabilizing device. A second rotating shaft is rotatably connected inside the nut seat. A lifting plate and rollers are mounted on the second rotating shaft. The rollers slide and rotate in the track. A connecting rod is installed between the two lifting plates. The lifting plates are rotatably connected to a horizontal plate. The connecting rod is rotatably connected to the stabilizing device. The second motor is connected to a controller. When the trailer is unloading, the manual control controller starts the second motor. The output shaft of the second motor drives the lead screw to rotate, which in turn drives the nut seat to slide away from the second motor. The nut seat then drives the second rotating shaft to slide on the track, which in turn drives the lifting plate to rotate away from the partition. The lifting plate then drives the cross plate to rotate, which in turn drives the trailer to rotate, lifting one side of the trailer to a specified angle. At the same time, the lead screw drives the first bevel gear to rotate, which in turn drives the stabilizing device to rotate. The stabilizing device supports the connecting rod, making the rotation of the lifting plate more stable.

[0011] The stabilizing device includes fixed blocks mounted on a partition. A third rotating shaft is rotatably connected between the two fixed blocks. A second bevel gear and a support plate are mounted on the third rotating shaft. The first and second bevel gears mesh. One end of the support plate rotates on a connecting rod. The first bevel gear drives the second bevel gear to rotate, which in turn drives the third rotating shaft to rotate. The third rotating shaft then drives the support plate to rotate away from the partition.

[0012] The initial positions of the short rod and the long rod of the first support device are opposite to the initial positions of the short rod and the long rod of the second support device.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. This invention enables the trailer to have a certain degree of autonomous power by installing an electric drive box. The independent electric drive system can directly drive the wheels through the motor, improving the overall energy efficiency, reducing the burden on the tractor, and extending the vehicle's range. Through the independent electric drive system, the new energy trailer can flexibly adjust the power output under complex road conditions, providing more stable handling.

[0015] 2. The anti-rollover device of the present invention can adjust the center of gravity of the trailer, so that the center of gravity is biased towards the tilted side, while supporting the tilted side to prevent the trailer from rolling over and ensure the driver's driving safety.

[0016] 3. The lifting device of the present invention can automatically lift the trailer box, which is convenient for unloading. There is no need for manual entry into the box to carry the goods, which reduces labor costs, reduces the labor intensity of manual labor, and improves work efficiency. At the same time, the stabilizing device can support the lifting device, making the operation of the lifting device more stable. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0025] Example: Figures 1-6 As shown, the present invention provides a technical solution: the electric drive device for a new energy trailer includes a trailer frame 1, an electric drive box 2 installed below the trailer frame 1, a tilt sensor installed below the electric drive box 2, a battery panel, a drive motor, a mechanical transmission device, a regeneration device, and a controller installed in the electric drive box 2, a wheel 3 installed on one side of the mechanical transmission device, a hydraulic cylinder 7 and an anti-rollover device 4 installed below the trailer frame 1, a support block 8 installed on the cylinder rod of the hydraulic cylinder 7, a partition 5 installed above the trailer frame 1, an automatic unloading device 6 installed on the partition 5, and the battery panel, drive motor, regeneration device, tilt sensor, and hydraulic cylinder 7 connected to the controller. When the trailer is at risk of tipping over, the tilt sensor under the electric drive box 2 detects the trailer tilting, and the controller activates the anti-tipping device 4 to adjust the trailer's center of gravity, shifting it towards the tilted side and providing support to prevent the trailer from tipping over. When unloading is required, the controller extends the cylinder rod of the hydraulic cylinder 7, which moves the support block 8 towards the ground until it touches the ground. The unloading door 62 of the trailer body 61 is then manually opened, and the controller is manually activated to activate the automatic unloading device 6. The trailer body 61 automatically tilts until it reaches the designated angle for unloading. After unloading is completed, the automatic unloading device 6 is activated to rotate the trailer body 61 back to its initial position, and the unloading door 62 is manually closed.

[0026] The anti-rollover device 4 includes a center of gravity adjustment device 41, a first support device 42, and a second support device 43. The center of gravity adjustment device 41 is installed below the trailer frame 1. A first gear 47 is installed at one end of the center of gravity adjustment device 41. A drive belt 46 meshes with the outer side of the first gear 47. A second gear 44 and a third gear 45 mesh with the inner wall of the drive belt 46. The second gear 44 rotates on the first support device 42, and the third gear 45 rotates on the second support device 43. The first support device 42 is installed on one side of the electric drive box 2, and the second support device 43 is installed on the other side of the electric drive box 2.

[0027] When the tilt sensor detects that the trailer is tilted towards the first support device 42, the controller activates the center of gravity adjustment device 41, increasing the weight on one side of the second support device 43, thus shifting the center of gravity towards the second support device 43. Simultaneously, the center of gravity adjustment device 41 drives the first gear 47 to rotate, which in turn drives the drive belt 46. The drive belt 46 then drives the second gear 44 and the third gear 45. The second gear 44 activates the first support device 42, placing it on the ground, while the third gear 45 moves the second support device 43 away from the ground. When the tilt sensor detects that the trailer is tilted towards the second support device 43, the controller activates the center of gravity adjustment device 41 to increase the weight on one side of the first support device 42, causing the center of gravity to shift towards the first support device 42. At the same time, the center of gravity adjustment device 41 drives the first gear 47 to rotate, the first gear 47 drives the transmission belt 46 to rotate, the transmission belt 46 drives the second gear 44 and the third gear 45 to rotate, and the third gear 45 activates the second support device 43, causing the second support device 43 to be supported on the ground. The second gear 44 then drives the first support device 42 away from the ground.

[0029] When the tilt sensor detects that the trailer is tilted towards the first support device 42, the controller starts the first motor 4106. The output shaft of the first motor 4106 drives the fourth gear 4107 to rotate, the fourth gear 4107 drives the fifth gear 4108 to rotate, the fifth gear 4108 drives the first shaft 4104 to rotate, the first shaft 4104 drives the sixth gear 4105 to rotate, the sixth gear 4105 drives the rack 4110 to slide towards the second support device 43, and the rack 4110 drives the moving plate 4109 to slide, so that the weight on the second support device 43 side is greater than the weight on the first support device 42 side. When the tilt sensor detects that the trailer is tilted towards the second support device 43, the controller reverses the first motor 4106 and repeats the above steps, so that the weight on the first support device 42 side is greater than the weight on the second support device 43 side.

The initial positions of the short rod 4202 and the long rod 4203 of the first support device 42 are opposite to the initial positions of the short rod 4202 and the long rod 4203 of the second support device 43.

[0031] When the tilt sensor detects that the trailer is tilted towards the first support device 42, the second gear 44 drives the rotating column to rotate, which in turn drives the short rod 4202 to rotate closer to the ground. The short rod 4202 drives the long rod 4203 to rotate, and the long rod 4203 drives the T-shaped plate 4205 to slide closer to the ground in the slide rail 4204.

The third gear 45 drives the rotating column of the second support device 43 to rotate, which in turn drives the short rod 4202 to rotate away from the ground, causing the caster 4206 of the second support device 43 to move away from the ground. When the tilt sensor detects that the trailer is tilted towards the second support device 43, the above steps are repeated, so that the caster 4206 of the second support device 43 touches the ground and the caster 4206 of the first support device 42 moves away from the ground.
