It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. In the following description, many specific details are set forth to fully understand the present disclosure. The described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments.

[0045] Figure 1 It is a schematic structural diagram of a thrust - lifting type vehicle carrier in the retracted state, Figure 2 It is a schematic structural diagram of a thrust - lifting type vehicle carrier in the opened state. As Figure 1 and Figure 2As shown in the figure, the thrust-lifting type vehicle transporter includes a vehicle body 10, a holding mechanism 20, a telescopic mechanism 40, and a lifting mechanism 30. The holding mechanism 20 is used to hold the wheels of the vehicle, and the lifting mechanism 30 is used to lift the wheels at the other end, so that the vehicle body 10 can move with the vehicle loaded, realizing the vehicle transportation function. The "lifting" action in this application refers to the action that the lifting mechanism 30 extends from the running surface where the wheel contacts the ground to the lower part of the wheel, so as to lift the wheel and carry the vehicle.

[0046] The vehicle body 10 is in a rectangular frame structure, and is provided with a plurality of traveling wheels and corresponding drivers to drive the traveling wheels to rotate. The overall width of the vehicle transporter is smaller than the distance between the vehicle wheels, and the overall height is lower than the height of the vehicle chassis, so that it can move under the vehicle through the traveling wheels to transport the vehicle.

[0047] The holding mechanism 20 is used to hold the front wheels or rear wheels of the vehicle, and those skilled in the art can set the control method of the holding mechanism 20 according to needs. The structure and control method of the holding mechanism 20 are existing. In Figure 1 and Figure 2 the shown embodiment, the holding mechanism includes a pair of push plates 22. Both ends of each push plate 22 are rotatably connected to a holding arm 21, and the push plate 22 is connected to the holding arm 21 through a connecting member 23. During operation, the pair of push plates 22 move towards each other, driving the holding arms 21 to move and at the same time driving the holding arms 21 to rotate through the connecting member 23, so that the holding arms 21 on the same side of the pair of push plates 22 hold the wheel simultaneously from both sides of the traveling direction of the wheel. However, the holding mechanism 20 is not limited to Figure 1 and Figure 2 the shown holding mechanism 20. The holding mechanism 20 can also be the handling device disclosed in Chinese Patent CN201010160150.0 Handling Device and Vehicle Transporter, the holding mechanism disclosed in Chinese Patent CN201410172726.3 Intelligent Transporter of a Stereo Garage, the holding mechanism disclosed in Chinese Patent CN205713319U Holding-Type Vehicle Transporter, and the wheel clamping device of a vehicle transporter disclosed in Chinese Patent CN109267795A. The above patent documents are incorporated into this application by reference and will not be elaborated here. During operation, taking the holding mechanism 20 holding the front wheels of the vehicle as an example, after the holding arms 21 of the holding mechanism 20 extend out, they clamp and lift the wheels from the front and rear sides of the wheels. After the wheels are lifted, the wheels are fixed by the holding mechanism 20 and cannot move.

[0048] Figure 3 is a schematic structural view of the lifting mechanism 30 in the retracted state, Figure 4 is a schematic structural view of the lifting mechanism 30 in the opened state. As Figure 3 and Figure 4As shown, the lifting mechanism 30 is used to lift the wheels (i.e., front wheels or rear wheels) of one end of the vehicle from the front and rear sides of the wheels after the holding mechanism 20 holds (i.e., fixes) the wheels of the vehicle, so that the vehicle carrier can lift the front wheels and rear wheels of the vehicle and move the loaded vehicle to a predetermined location to complete the vehicle handling operation.

[0049] In this embodiment, the lifting mechanism 30 includes a bottom frame 31, lifting arms 32, a drive assembly, support wheels 35 and drive wheels 36. The lifting arms 32 are movably mounted on the bottom frame 31 so as to be able to expand or contract and move to both sides in the moving direction of the bottom frame 31. In this embodiment, the lifting arms 32 can be expanded or contracted from both sides of the bottom frame 31 by rotation. The drive assembly is used to drive the lifting arms 32 to expand (i.e., extend) or contract (i.e., retract), and the support wheels and drive wheels 36 are used to support and drive the movement of the bottom frame 31, and cooperate with the telescopic mechanism 40 to drive the lifting arms 32 to lift the wheels. In some other embodiments, the bottom frame 31 can also be moved independently by the telescopic mechanism 40 or the drive wheels 36.

[0050] The bottom frame 31 is movably connected to the vehicle body 10. In this embodiment, the bottom frame 31 can be movably connected to the end position of the vehicle body 10 through a two-stage, three-stage or more telescopic mechanism 40, so that the bottom frame 31 can move back and forth relative to the vehicle body 10 along the vehicle traveling direction. To improve the load-bearing capacity of the bottom frame 31, in this embodiment, the bottom frame 31 is also provided with support wheels 35 and drive wheels 36. The number of support wheels is two, which are respectively rotatably arranged on both sides of the bottom frame 31. The drive wheels 36 are rotatably connected to the bottom frame 31 and are used for the bottom frame 31 to move relative to the vehicle body 10. In this embodiment, the bottom frame 31 is also provided with a battery pack 361 and a driver. The driver is connected to the drive wheels 36 and drives the drive wheels 36 to rotate under the power supply of the battery pack 361, so as to be able to pull the bottom frame 31 to move back and forth relative to the vehicle body 10 under the support of the support wheels 35.

[0051] The end of the lifting arm 32 is rotatably connected to the bottom frame 31 through a bearing, and is used to move close to the wheel at the other end after the holding mechanism 20 holds the wheel at one end of the vehicle until the wheel is lifted. In this embodiment, the lifting arm 31 has a wedge-shaped structure with a smaller thickness at the front than at the rear. The thickness of the wedge-shaped opening at the front is smaller, while the thickness at the rear is larger. In this way, the wedge-shaped opening at the front can facilitate cutting into the lower part of the wheel, and the rear part can stop the wheel to prevent the wheel from disengaging from the lifting arm 31. The lifting arm 32 is rotatably connected to the bottom frame 31 and rotates 180° relative to the bottom frame 31. The lifting mechanism 30 further includes a limit block, and the limit block is connected to the bottom frame 31. When the drive unit drives the lifting arm 32 to rotate until it abuts against the limit block, the lifting arm 32 is in the unfolded state for docking with the wheel. When the lifting arm 32 rotates to the open state, the wedge-shaped opening at the front is located on the side close to the wheel. Since the thickness of the rear part is larger, it can prevent the risk of the wheel from crossing over the lifting arm 32. When the lifting arm 32 rotates 180° to the retracted state, the wedge-shaped openings of a pair of lifting arms 32 face each other, and the lifting arm 32 is completely retracted within the width range of the bottom frame 31 to avoid obstructing the passage of the vehicle transporter under the vehicle. Those skilled in the art understand that the wedge-shaped lifting arm 31 is not necessary, and other shaped lifting arms 31 can also cut into the lower part of the wheel to lift the vehicle. Those skilled in the art can also set some rollers at the front of the lifting arm 31 to facilitate cutting into the wheel.

[0052] The drive assembly for driving the lifting arm 32 to rotate. In this embodiment, the drive assembly includes a sliding plate 34, a connecting rod 33, and a drive unit (not shown in the figure). The sliding plate 34 is movably connected to the bottom frame 31 along the traveling direction of the vehicle through a slide rail-slider structure. In this embodiment, the slide rail 341 is provided on the bottom frame 31, and the sliding plate 34 is movably connected to the slide rail 341. The connecting rod 33 has a semi-"U" shaped structure, with one end rotatably connected to the sliding plate 34 and the other end rotatably connected to the lifting arm 32. Among them, the position where the lifting arm 32 is connected to the connecting rod 33 deviates from the position where it is connected to the bottom frame 31. In this way, when the sliding plate 34 moves, it can drive the lifting arm 32 to rotate relative to the bottom frame 31 through the connecting rod 33. The drive unit is connected to the sliding plate 34 and is used to drive the lifting arm 32 to rotate through the sliding plate 34 and the connecting rod 33.

[0053] The above-mentioned thrust-lifting type vehicle transporter is further configured with a controller and a memory. The memory stores programs and data for controlling the thrust-lifting type vehicle transporter. After the controller reads the programs and data, it drives the thrust-lifting type vehicle transporter to implement the following thrust-lifting type vehicle handling method. The method includes the following steps:

[0054] S1: After the vehicle carrier moves below the vehicle, the holding mechanism 20 holds the wheels at one end of the vehicle. Taking the holding mechanism 20 holding the front wheels of the vehicle as an example, after the vehicle carrier moves below the vehicle, the holding mechanism 20 is located at a position corresponding to the front wheels of the vehicle, and then the two holding arms 21 of the holding mechanism 20 hold the tires from the front and rear sides of the front wheels respectively, lifting the front wheels of the vehicle. At this time, the front wheels of the vehicle are in a fixed state.

[0055] S2: The bottom frame 31 of the lifting mechanism 30 moves relative to the vehicle body 10 of the vehicle carrier, driving the lifting arm 32 to embed under the wheels at the other end of the vehicle to lift the wheels. In this step, taking the holding mechanism 20 holding the front wheels of the vehicle and the lifting mechanism 30 lifting the rear wheels of the vehicle as an example for illustration. After the controller detects that the holding arms 21 of the holding mechanism 20 hold the front wheels, the sliding plate 34 drives the lifting arm 32 to rotate to the open state through the connecting rod 33, and the driver pulls the driving wheel 36 to load the bottom frame 31 to move in a direction away from the holding mechanism 20, lifting the wheels from the inner side of the wheels, that is, the opening of the lifting arm 32 extends from the front side of the rear wheels under the rear wheels to lift the rear wheels. Since the lifting arm 32 does not need to hold or clamp the tires from the front and rear sides of the rear wheels, even if there is a vehicle stopper at the rear side of the rear wheels, it will not prevent the lifting arm 32 from lifting the vehicle, thus avoiding the vehicle stopper from hindering the vehicle carrier from carrying the vehicle.

[0056] In some other embodiments, the bottom frame 31 moves in a direction close to the holding mechanism 20 to lift the wheels from the outside of the wheels. Specifically, after the controller detects that the holding mechanism 20 holds the front wheels or rear wheels of the vehicle, it controls the lifting arm 32 to move towards the wheels from the outside of the wheels, lifting the wheels from the side away from the holding mechanism 20, thus avoiding the vehicle stopper on this side from hindering the vehicle carrier from carrying the vehicle. Those skilled in the art can set the direction of the lifting mechanism 30 to lift the wheels according to the actual situation, and this application does not limit this.

[0057] Figure 5 is a schematic structural diagram of another lifting mechanism. As Figure 5 shown, different from the Figure 3 and Figure 4 shown lifting mechanism 30, Figure 5The lifting arm 32 of the shown lifting mechanism 30 is movably and telescopically connected to the bottom frame 31. Specifically, the lifting arm 32 is movably connected to the bottom frame 31 along both sides in the length direction of the vehicle body 10. For example, it can be movably connected to the bottom frame 31 along both sides in the traveling direction of the bottom frame 31 by means of a slider-rail, rollers and roller grooves, etc. The lifting mechanism 30 further includes a driving assembly for driving the telescopic movement of the lifting arm 32. As an example, the driving assembly includes a driving gear 37 and a driver (not shown in the figure). The driving gear 37 is rotatably connected to the bottom frame 31. A pair of the lifting arms 32 are arranged to move relatively, and teeth 321 are arranged along the length direction on the relative sides. The driving gear 37 meshes with the teeth 321 of the pair of lifting arms 32. The driver can be a motor, and the output shaft is connected to the driving gear 37 for synchronously driving a pair of the lifting arms 32 to extend or retract from the bottom frame 31 by driving the driving gear 37 to rotate. During operation, when the driver drives the driving gear 37 to rotate forward or backward, a pair of the lifting arms 32 can be synchronously driven to extend or retract and move from both sides of the bottom frame 31.

[0058] Figure 6 is a schematic structural diagram of the telescopic mechanism. As Figure 6 shown, the telescopic mechanism 40 is used to drive the lifting mechanism 30 to move closer to or away from the wheels relative to the vehicle body 10. As an example, the telescopic mechanism 40 includes a first telescopic arm 41, a second telescopic arm 42 and a driving assembly. A telescopic motor 43 and a lead screw 44. The first telescopic arm 41 is movably connected to the vehicle body 10 along the telescopic direction. The second telescopic arm 42 is movably connected to the first telescopic arm 41 and is connected to the bottom frame 34. Specifically, a row of rollers 45 are arranged along the telescopic direction on both sides of the vehicle body 10. Roller grooves 451 are provided on both side surfaces of the first telescopic arm 41. The first telescopic arm 41 realizes relative movement along the telescopic direction with respect to the vehicle body 10 by the rollers 45 being embedded in the roller grooves 451; similarly, roller grooves 451 are also provided on the outer side surfaces on both sides of the first telescopic arm 41. Rollers 45 are provided on both sides of the second telescopic arm 42. The second telescopic arm 42 also realizes telescopic movement along the telescopic direction relative to the first telescopic arm 41 by the rollers 45 being embedded in the roller grooves 451. The driving assembly is connected to the first telescopic arm 41 and the second telescopic arm 42 for driving the first telescopic arm 41 to move relative to the vehicle body 10 and driving the second telescopic arm 42 to move relative to the first telescopic arm 41. In this embodiment, the driving assembly includes a telescopic motor 43 and a lead screw 44, and drives the first telescopic arm 41 and the second telescopic arm 42 to telescopically move through the telescopic motor 43 and the lead screw 44.

[0059] During operation, the first telescopic arm 41 moves relative to the vehicle body 10, and the second telescopic arm 42 moves relative to the first telescopic arm 41 to drive the bottom frame 34 to move closer to or away from the wheels. In some other embodiments, the telescopic mechanism 40 can also be other mechanisms. For example, it can be a lead screw 44-nut structure to drive the bottom frame 34 to move, or it can be a hydraulic or pneumatic manner to drive the bottom frame 34 to move. The present application does not limit this.

[0060] After the above-mentioned thrust-lifting type vehicle transporter and transportation method hold the wheels at one end of the vehicle through the holding mechanism 20, the lifting arm 32 of the lifting mechanism 30 lifts the wheels at the other end of the vehicle, so that it is not necessary to lift the wheels from both sides of the wheels, avoiding the vehicle stopper in the parking space from hindering the vehicle transportation operation. The vehicle transporter can lift the vehicle tire with only one-sided operation. The vehicle body 10 is small and can enter under the vehicle from the side of the vehicle, effectively overcoming the obstacle of the vehicle stopper to the transported vehicle, adapting to various parking space scenarios, including the situation where there is a vehicle stopper and the clamping space of a conventional AGV is insufficient. It can respond quickly during emergency transportation, improving the timeliness and flexibility of vehicle transportation.
