Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1-2, fig. 1 is a schematic structural view of an embodiment of a vehicle carrier according to the present disclosure; fig. 2 is a schematic view of the vehicle carrier of fig. 1 with the protective cover and chain removed.

The vehicle carrier 10 includes a carrier body 100, two sets of transport modules 200, and a driving unit 300.

The driving portion 300 is disposed in the middle region of the carrier body 100, the two sets of transporting assemblies 200 may be disposed on two opposite sides of the carrier body 100, and the driving portion 300 may be connected to the two sets of transporting assemblies 200 to provide power to the two sets of transporting assemblies 200, so as to transmit the vehicle carried on the transporting assemblies 200 to a predetermined direction.

In this embodiment, the transmission directions of the two sets of transportation assemblies 200 may extend along the length direction of the carrier body 100, and the distance between the two sets of transportation assemblies 200 may be matched with the width of the vehicle, so that the front wheels and the rear wheels of the vehicle located on the same side may be borne on the same set of transportation assemblies 200. For example, the vehicle front left wheel and rear left wheel may be carried on one of the sets of transport assemblies 200; the vehicle right front and rear wheels may be carried on another set of the transport assemblies 200.

In this embodiment, the driving unit 300 is disposed at the middle position of the carrier main body 100, and the driving unit 300 is usually higher than the carrying surface of the transportation module 200 because the driving unit 300 needs to be provided with a power source such as a battery, a motor, and the like and a controller. Also, when the vehicle is completely placed on the vehicle carrier 10 (the left and right front wheels and the right and front wheels of the vehicle are respectively carried on the two sets of the transport assemblies 200), the driving portion 300 needs to be disposed at a distance from the chassis of the vehicle.

However, when the vehicle is not completely placed on the vehicle carrier 10, that is, during the transportation of the vehicle along with the transportation assemblies 200 (for example, when the front left wheel and the front right wheel of the vehicle are respectively carried on the two transportation assemblies 200, and the rear left wheel and the rear right wheel of the vehicle are carried on the ground), the chassis of the vehicle is inclined with respect to the ground as a whole, and at this time, the end of the driving portion 300 is easily worn away from the chassis of the vehicle during the loading of the vehicle along with the relative displacement of the vehicle and the vehicle carrier 10, so that the vehicle is gradually and completely loaded on the loading surface of the transportation assemblies 200.

In the scheme of the application, the height of the edge area 301 of the driving part 300 on the side exceeding the bearing surface is set to be smaller than that of the middle area 302. Specifically, on the side of the driving part 300 beyond the carrying surface of the transportation assembly 200, the distance between the edge area 301 of the driving part 300 and the carrying surface is smaller than the distance between the middle area 302 of the driving part 300 and the carrying surface. And when the vehicle is loaded and carried on the carrying surface, the middle area 302 of the driving part 300 is spaced from the lowest point of the chassis of the vehicle. Therefore, with the above-described arrangement, it is possible to avoid the edge area 301 of the driving portion 300 from contacting the chassis of the vehicle to cause the chassis of the vehicle to wear.

In this embodiment, the driving unit 300 needs to be provided with a power source such as a battery and a motor and a component such as a controller, and therefore, a protective cover 600 may be further covered on one side of the power source such as a battery and a motor and the component such as a controller on the bearing surface, where the protective cover 600 may be used to cover and protect each component in the driving unit 300.

In this embodiment, the side of the protective cover 600 facing away from the carrier main body 100 may be disposed toward the chassis of the vehicle. The setting of the height of the edge area 301 of the driving part 300 on the side beyond the bearing surface to be smaller than the height of the middle area 302 may specifically be represented as: the distance between the middle area of the side surface of the protective cover 600 facing away from the carrier body 100 and the carrier body 100 is larger than the distance between the edge area of the surface and the carrier body 100. Therefore, by recessing the edge region of the side surface of the protective cover 600 away from the carrier main body 100 in the direction close to the carrier main body 100, the edge region of the protective cover 600 and the lowest point of the vehicle chassis do not touch each other during the process that the vehicle enters the carrier main body 100, so that the vehicle carrier 10 can adapt to more vehicles with chassis of different heights, and the chassis is not scratched, thereby protecting the safety of the vehicle.

In this embodiment, the edge region of the protective cover 600 may be optionally provided as a slope or an arc surface inclined to the side close to the carrier main body 100.

The protective cover plate 600 may be integrally formed by stamping, casting, or the like; or a plurality of separate components may be formed by splicing.

When the protective cover 600 is formed by splicing, the protective cover 600 may include a middle part 610 and two end parts 620, and the two end parts 620 respectively form the inclined surfaces or the arc surfaces at the edge regions of the protective cover 600. The two end members 620 may be located on opposite sides of the middle member 610, and the central connection of the two end members may be parallel to the length direction of the carrier body 100.

Further, alternatively, the protective cover 600 may be detachably attached to the carrier main body 100 by a fastener such as a screw; or may be fixedly attached to the carrier body 100 by welding or bonding.

Further, in this embodiment, the carrier main body 100 is a frame of the entire vehicle carrier 10, and is configured to carry various components on the carrier, wherein the carrier main body 100 includes a central frame 110 and side frames 120, and a certain distance is left between the central frame 110 and the side frames 120, so that the central frame 110 and the side frames 120 enclose two driving grooves 101, both the driving grooves 101 extend along a length direction of the carrier main body 100, and the driving grooves 101 are respectively disposed on two sides of the vehicle carrier 10 in a width direction. The center frame 110 is located in the area between the two running grooves 101.

The two sets of transportation assemblies 200 are respectively installed on the two running grooves 101. In this embodiment, the two driving slots 101 may be parallel and spaced apart, and the two corresponding sets of transporting assemblies 200 are also parallel and spaced apart.

In this embodiment, each set of transporting assemblies 200 includes at least two parallel chains 210, and the chains 210 can move along the guideway 101 in one or two directions to transport the vehicle to the carrier. The two directions may mean that the chain 210 is transported back and forth along the length direction of the carrier body 100.

The chain 210 may be looped around and/or wound around a plurality of connecting rollers 220 and a driving roller 230.

In this embodiment, the chain 210 is used as a carrier for transporting the vehicle, and since the friction between the chain 210 and the wheels of the vehicle is large, when the vehicle is transported by the chain 210, the problem of position deviation of the vehicle when entering the vehicle carrier 10 due to slipping of the wheels of the vehicle can be avoided.

In this embodiment, the driving roller 230 may be used to be connected to a power output end of a driving assembly 310 in the driving portion 300, and the driving roller 230 may be driven to rotate by the driving assembly 310, and further the connecting roller 220 may be driven to rotate by the chain 210.

Alternatively, gears are disposed on both the connecting roller 220 and the driving roller 230, and the chain 210 can be meshed with the gears of both the connecting roller 220 and the driving roller 230.

In the present embodiment, please refer to fig. 5, which is a schematic structural diagram of the battery pack in the vehicle carrier shown in fig. 2 after rotating 180 °. The battery pack 320 is disposed in the center region of the carrier body 100, and the battery pack 320 may be provided with a clearance groove 321 for disposing the driving unit 310. By disposing the driving assembly 310 in the clearance groove 321 on the battery pack 320, the battery pack 320 and the driving assembly 310 can be mounted compactly while ensuring the size of the battery pack 320, thereby saving the mounting space.

Wherein, optionally, the battery pack 320 may be L-shaped as a whole. The driving element 310 may be placed in the L-shaped gap.

In addition, since the battery pack 320 and the driving assembly 310 are relatively thick and both can be mounted in the central region of the carrier main body 100, the battery pack 320 and the driving assembly 310 can be covered and protected by the middle member 610 having a relatively higher height.

Further, in this embodiment, the driving assembly 310 and the driving roller 230 may be connected by a coupling 240, and the coupling 240 may be in an H shape, and opposite ends of the coupling 240 may be engaged with the driving shaft of the coupling 240 and the driving roller 230, respectively.
