[0063] In an optional embodiment of the present application, the side edges of the first and second telescopic control plates 431 and 432 are connected with the ends of the first and second lifting rods 31 and 32.

[0064] The first and second telescopic control plates 431 and 432 move to push the first and second lifting rods 31 and 32 to move.

[0065] In the embodiment, when the first and second telescopic control plates 431 and 432 move towards the end of the bottom plate, the side edges press the first and second lifting rods 31 and 32, so that the first and second lifting rods 31 and 32 extend from the side plate 13 to clamp the vehicle tire.

[0066] When the first and second telescopic control plates 431 and 432 move to the center position, the first and second lifting rods 31 and 32 are retracted to put down the tire.

[0067] In an optional embodiment of the present application, the traveling guide wheels telescopic rod 51 is provided with traveling guide wheels 52 at the end.

[0069] When the flat car is about to run to the ground, the traveling guide wheels telescopic rod 51 is retracted in advance to prevent the traveling guide wheels 52 from being damaged due to the too long telescopic rod.

[0070] In an optional embodiment of the present application, the lifting device 6 is arranged on the bottom plate 12 and extends in the direction perpendicular to the bottom plate 12.

[0071] In this embodiment, the lifting device 6 is located at the four corners of the vehicle bottom plate 12. Sensors are provided inside the lifting device 6 to sense the weight of the vehicle and determine the required lifting force, thereby controlling the lifting of the flatbed truck.

[0072] The lifting device 6 may provide lifting force by means of hydraulic or air suspension.

[0073] In an optional embodiment of the present invention, a second motor is provided inside the lifting device 6;

[0074] The driving wheel 7 is connected to the second motor, and the second motor drives the driving wheel 7 to rotate.

[0075] In this embodiment, the driving wheel 7 is connected to the second motor inside the lifting device 6, and the driving wheel 7 is driven to rotate by the second motor, thereby providing power for the flatbed truck and driving the flatbed truck to move.

[0076] In an optional embodiment of the present invention, the intelligent flatbed truck for loading and unloading vehicles further includes: an auxiliary device 8, and the auxiliary device 8 is engaged with the travel guide wheel 52.

[0077] In an optional embodiment of the present invention, the auxiliary device 8 includes:

[0078] A track 81 is provided on the auxiliary device 8, and the travel guide wheel 52 moves along the track 81;

[0079] Tire traps 82 are provided on both sides of the track 81 .

[0080] In the above embodiment, Figure 4 As shown, the auxiliary device 8 is mainly used to modify the platform carrying the vehicle in the automobile transporter, and corresponding tracks 81 and tire pits 82 are set on the platform.

[0081] The track 81 is a rectangular groove that engages with the travel guide wheel 52 on the flatbed vehicle. Combined with the track, the smart flatbed vehicle does not deviate during movement and always remains in the middle of the vehicle transport vehicle, ensuring the safety of the vehicle during loading and unloading.

[0082] The tire trap 82 is arc-shaped, matching the shape and size of the vehicle tire. When the tire is lowered, it will sink into the tire trap 82, thereby securing the vehicle and ensuring its safety during transportation. When the vehicle needs to be moved, the first and second lifting rods 31, 32 of the flatbed truck extend to lift the vehicle out of the tire trap 82, allowing it to be moved again.

[0083] Optionally, the intelligent flat car of the loading and unloading vehicle is internally provided with a mobile power supply, which provides a power source for the flat car, and does not need to be connected with an external power supply through a wire, thereby increasing the activity range of the flat car.

[0084] The intelligent flat car of the loading and unloading vehicle described in the above embodiments has the following specific working process:

[0085] The flat car travels to the bottom of the vehicle under the guidance of the first camera 21, and the flat car is accurately positioned by the start working of the flat car distributed on both sides of the flat car and accurately finding the position of the vehicle tire;

[0086] Then, the first motor 41 works to drive the gear 42 to rotate, and through the mutual combination of the gear 42 and the racks at the tail of the first telescopic control plate 431 and the second telescopic control plate 432, an outward pushing force is given to the telescopic control plates. The first telescopic control plate 431 and the second telescopic control plate 432 move symmetrically to both ends of the bottom plate 12 under the guidance of the pulleys 44 fixed in the grooves of the bottom plate 12, thereby pushing the first lifting rods 31 and the second lifting rods 32 at the four corners to extend from the side plates 13 to clamp the vehicle tires, facilitating subsequent vehicle transfer;

[0087] After the lifting rods extend, the lifting device 6 works to lift the flat car together with the vehicle. Then, the second motor drives the driving wheels 7 to work to drive the flat car to move.

[0088] When the flat car travels to the auxiliary device 8 on the automobile transport platform, the first camera 21 guides the flat car to align the track 81 on the auxiliary device 8, and then the flat car travels to the platform, the travel guide wheels 52 on the bottom plate 12 extend to abut against both sides of the track to prevent the flat car from deviating during running on the platform, thereby causing vehicle collision;

[0089] Then, the flat car runs to the designated position on the automobile transport platform, the lifting device 6 retracts, the flat car lowers, the vehicle is placed down, and through the accurate positioning of the second camera 22 and the first camera 21, the vehicle is accurately placed in the tire pit 82 on the automobile transport platform, thereby ensuring the safety of vehicle transportation;

[0090] Then, the first motor 41 works to rotate, the first telescopic control plate 431 and the second telescopic control plate 432 retract, the lifting rods automatically retract, the flat car exits the platform along the track 81, and when the flat car approaches the ground, the travel guide wheel telescopic rod 51 retracts, the travel guide wheel 52 retracts, the flat car runs to the ground, finds the next vehicle, and repeats the above operation to continue loading the vehicle.

[0091] The unloading process is opposite to the above process. First, under the action of the first camera 21 and the second camera 22, the flat car is driven to the bottom of the vehicle, and the lifting rod is aligned with the tire pit 82. Then, the lifting rod is extended to clamp the tire, the lifting device 6 works to lift the vehicle, and the tire is lifted away from the tire pit. After lifting, the driving wheel 7 rotates, the flat car drives away from the car transport platform along the track 81. When approaching the ground, the travel guide wheel telescopic rod 51 is retracted, the travel guide wheel 52 is retracted, the flat car is driven to the designated position on the ground under the action of the first camera 21 and the second camera 22. Then, the flat car is lowered, the lifting rod is retracted, the flat car exits the bottom of the vehicle, and the unloading is completed.

[0092] The intelligent flat car for loading and unloading vehicles described in the present application automatically finds the position of the vehicle through the camera and fixes the vehicle with the lifting rod. The lifting device lifts the vehicle, and then the driving device drives the whole vehicle to move on the fixed track in combination with the guide wheel, so as to load and transport the vehicle to the designated position and fix it. The whole vehicle loading and unloading process is automated and intelligent, the loading and unloading efficiency is improved, and the safety of the whole loading and transportation process is improved. The whole loading process does not require the power of the vehicle itself and does not require professional drivers to operate, which saves the cost of manpower and material resources in the whole loading and unloading process and reduces the work burden of the transportation driver.

[0093] When the intelligent flat car completes the loading and unloading task of the car on the platform, the intelligent flat car always drives along the specific track under the action of the travel guide mechanism, strictly ensures that the transported vehicle can accurately reach the designated position, and ensures that the vehicle is always in the middle position of the loading platform, so that the vehicle will not be scratched during loading and unloading. After the vehicle is placed in the designated position of the platform, it will also be fixed by the corresponding tire pit to ensure the safety of the vehicle during transportation. In addition, the intelligent flat car can strictly control the distance between adjacent vehicles during loading of the vehicle, so as to avoid rear-end accidents that may occur during loading in a narrow space. The intelligent flat car does not need to start the vehicle, and the loading and unloading of the vehicle will not be affected when the vehicle loses power, especially when the new energy vehicle is out of power and cannot be immediately supplemented.

[0094] The intelligent flat car for loading and unloading vehicles described in the present application has little requirement for the structure of the car transport vehicle, only needs slight modification, sets corresponding tracks for the flat car and sets corresponding tire pits for the car, does not require other special equipment, has strong applicability, and can be widely applied to various car transport vehicles. The implementation of this technology can provide reliable technical support for the intelligent transformation and development of the whole industry.

[0095] The above is the preferred embodiment of the present application. It should be noted that for ordinary skilled persons in the technical field, some improvements and refinements can be made without departing from the principles of the present application, and these improvements and refinements should also be considered within the protection scope of the present application.
