Description

Technical Field

[0002] New energy vehicles refer to all other energy vehicles except gasoline and diesel engines, including fuel cell vehicles, hybrid vehicles, hydrogen energy-powered vehicles, solar vehicles, etc. With the increase in the sales volume of new energy vehicles, some new energy trucks in the market also have a good market, especially some electric vehicles and hybrid vehicles.

[0003] After retrieval, the "cargo box for a new energy vehicle" disclosed in Chinese Patent (Publication No.: CN208906758U) includes a bottom plate, a front plate, a rear plate, a left plate, and a right plate respectively connected to the four sides of the bottom plate. The rear plate is hinged to the bottom plate through a connecting key. Cavities are provided at corresponding positions of the left plate and the right plate. A connecting rod is movably arranged in the cavity, and a limiting ring is provided at the port of the connecting rod. One end of the connecting rod passes through the cavity circle of the limiting ring and is fixedly connected to the rear plate, and a limiting disc is provided at one end. The cavity is an arc cavity, the connecting rod is an arc connecting rod, the length of the connecting rod is the same as the length of the cavity, and the diameter is smaller than the diameter of the cavity. The diameter of the limiting disc is larger than the diameter of the cavity circle of the limiting ring.

[0004] However, in the process of implementing related technologies, there are some technical defects in this type of patent:

[0005] First, although the rear plate of the cargo box is used to extend the loading length in this type of patent, during the process of loading and unloading goods, it mainly relies on manpower to unload or load the goods, and it is more difficult to load and unload some large-sized goods. Some cargo boxes also adopt a tipping design, which only facilitates unloading, but loading still requires manual handling, and this tipping type of unloading is likely to cause the goods to be squeezed and collided with each other, resulting in damage.

A motor 53 is fixedly installed at one end of the inner side of the box body 1, and the output shaft of the motor 53 is fixedly connected to one of the first conveyor rollers 51. A first support plate 54 is fixedly connected to the bottom end of the inner side of the box body 1, and the first support plate 54 is located on the inner side of the first conveyor belt 52. A limit piece 55 is arranged at one end of one of the first conveyor rollers 51 to limit the rotation of the first conveyor roller 51 by cooperating with the closing of the box door panel 2, and a second conveying mechanism 6 is arranged on the inner side of the box door panel 2 to transport the goods by cooperating with the rotation of the first conveyor roller 51.

[0036] During loading, the door panel 2 is opened by controlling the hydraulic rod 3, and then the goods are moved to the second conveying mechanism 6 on the door panel 2, and then the motor 53 is started to drive the corresponding first conveying roller 51 to rotate, so that the second conveying mechanism 6 conveys the goods to the first conveyor belt 52 in the box body 1, and the first conveyor belt 52 cooperates with the rotation of the first conveying roller 51 to convey the goods to the inside of the box body 1, and then the hydraulic rod 3 is controlled to drive the door panel 2 to close to complete the loading; similarly, during unloading, the door panel 2 is opened by controlling the hydraulic rod 3, and then the motor 53 is started to drive the first conveying roller 51 to rotate in the opposite direction, so that the first conveyor belt 52 conveys the goods to the door panel 2, and then the second conveying mechanism 6 conveys the goods to the unloading position for easy unloading.

At this time, the rotating block 551 is restricted and cannot rotate, so that the first conveying roller 51 cannot rotate.

[0040] Furthermore, the second conveying mechanism 6 includes two second conveying rollers 61 arranged in parallel, one of which is rotatably connected to the inner side of the fixing seat 7, one end of the second conveying roller 61 passes through the rotating shaft of the door panel 2 and is rotatably connected to the door panel 2, and the end of the second conveying roller 61 is provided with a transmission member 64 which drives the second conveying roller 61 to rotate by cooperating with the rotation of the first conveying roller 51, and the other second conveying roller 61 is rotatably connected to one end of the inner side of the door panel 2, and a second conveying roller 64 is provided between the two second conveying rollers 61. Belt 62, two second conveyor rollers 61 are connected by the second conveyor belt 62, the inner side of the box door panel 2 is fixedly connected with a second support plate 63, the second support plate 63 is located on the inner side of the second conveyor belt 62, the transmission member 64 includes a first gear 641, the first gear 641 is coaxially fixedly connected with the second conveyor roller 61, one end of the outer side of the box body 1 is rotatably connected with a second gear 642 meshing with the first gear 641, and one of the first conveyor rollers 51 is coaxially fixedly connected with a third gear 643 meshing with the second gear 642.

[0041] By starting the motor 53 to drive the corresponding first conveyor roller 51 to rotate, under the transmission action of the first conveyor belt 52, the two first conveyor rollers 51 rotate synchronously, so that the third gear 643 rotates synchronously, and the second gear 642 rotates, so that the first gear 641 drives the second conveyor roller 61 to rotate synchronously, and then the second conveyor belt 62 conveys the goods in the same conveying direction as the first conveyor belt 52. In this way, the first conveyor belt 52 can cooperate with the second conveyor belt 62 to load and unload goods, which greatly reduces the amount of manual labor and also improves the loading and unloading efficiency of goods.

[0042] Further, the clamping mechanism 4 includes a partition 41, which is fixedly connected to the top of the inner side of the box body 1, and a plurality of pressure rods 42 penetrating the partition 41 are slidably connected to the partition 41, and the plurality of pressure rods 42 are equidistantly distributed along the length direction of the partition 41, and the bottom ends of the plurality of pressure rods 42 are fixedly connected to a pressure plate 43, and the top ends of the plurality of pressure rods 42 are provided with a top pressure piece 44 which drives the pressure rod 42 to slide downward by cooperating with the closing of the box door plate 2, and the top pressure piece 44 includes a plurality of protrusions 441 corresponding to the pressure rods 42 one by one, and the plurality of protrusions 441 are fixedly connected to the top ends of the corresponding pressure rods 42, and the plurality of pressure rods 42 are sleeved with a return spring 44. 2, one end of a plurality of return springs 442 contacts with the corresponding protrusions 441, and the other ends of a plurality of return springs 442 contact with the partition plate 41, a sliding rod 443 is connected to the sliding inside of the box body 1, and a plurality of arc top blocks 444 corresponding to the protrusions 441 are fixedly connected to the sliding rod 443, and the plurality of arc top blocks 444 contact with the corresponding protrusions 441 by cooperating with the sliding of the sliding rod 443, a pressure plate 445 is hinged at one end of the sliding rod 443, and the box door panel 2 contacts with the pressure plate 445 by rotating, and a clearance groove 8 is provided at one end of the box door panel 2, and the pressure plate 445 contacts with the inner wall of the clearance groove 8 when the box door panel 2 is closed.

[0043] Working principle: When loading, the box door panel 2 is driven to open by controlling the hydraulic rod 3, and then the goods are transported to the second conveyor belt 62 on the box door panel 2, and then the motor 53 is started to drive the corresponding first conveyor roller 51 to rotate. Under the transmission action of the first conveyor belt 52, the two first conveyor rollers 51 rotate synchronously, so that the third gear 643 rotates synchronously, and the second gear 642 rotates, so that the first gear 641 drives the second conveyor roller 61 to rotate synchronously and in the same direction as the first conveyor roller 51, so that the second conveyor belt 62 transports the goods to the first conveyor belt 52, and then the first conveyor belt 52 transports the goods to the inside of the box body 1 to complete the loading;

[0044] After loading is completed, the hydraulic rod 3 is controlled to drive the box door plate 2 to close, so that the box door plate 2 contacts the pressure plate 445 and applies thrust to it, so that the pressure plate 445 drives the slide bar 443 to slide, so that all the arc top blocks 444 contact the corresponding protrusions 441, so that the protrusions 441 are squeezed and move downward, which makes all the pressure rods 42 slide downward synchronously. At this time, the return spring 442 is compressed and accumulates potential energy, which makes the pressure plate 43 move downward and exerts pressure on the goods, so that the goods remain stable inside the box body 1, effectively avoiding the problem of shaking and collision damage of the goods during the driving of the car;

[0045] When the door panel 2 is closed, the elastic limiting rod 553 can be slidably matched with one of the limiting holes 552, and the rotating block 551 is restricted and cannot rotate, so that the first conveying roller 51 cannot rotate, which can avoid the problem that the goods are violently shaken and damaged due to the inertia of the goods during transportation;

[0046] When unloading, the box door panel 2 is driven to open by controlling the hydraulic rod 3. At this time, the elastic limiting rod 553 can be separated from the limiting hole 552 to release the restriction on the first conveying roller 51. At the same time, the reset spring 442 releases the potential energy to make the pressure plate 43 move upward and separate from the goods. Then the motor 53 is started to drive the first conveying roller 51 to rotate in the opposite direction, so that the first conveyor belt 52 cooperates with the second conveyor belt 62 to transport the goods to the unloading position to facilitate unloading. This loading and unloading method can greatly reduce the difficulty of loading and unloading of goods, and improve the loading and unloading efficiency and safety.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
