Description

Technical Field

[0001] The present disclosure belongs to the field of vehicle handling equipment, and in particular, to a vehicle handler. Background Art

[0002] Parking spaces correspond to automated parking equipment, and generally have the following parking methods:

[0003] Mother - son type AGV: The mother vehicle transports the son vehicle and the car, and the son vehicle is responsible for transporting the car to the mother vehicle. The disadvantage is that a specially designed parking platform is required to meet the handling conditions, either by raising the parking platform or designing a special platform.

[0004] Car - board type AGV: Transports the car by carrying the car - board that supports the car on the vehicle. The disadvantage is also that the car - board needs to be transported, and there are special requirements for the parking platform.

[0005] Holding type AGV (such as gantry AGV, RAY parking robot, ultra - thin holding type AGV): Can transport cars without a convex platform. However, in a parking garage, there are generally obstacles such as car stoppers in the parking space. The holding type AGV is restricted by the car stoppers in the parking space and cannot transport the vehicle on the parking space with car stoppers. Summary of the Invention

[0006] In view of the above, it is necessary to provide a bilateral - thrust lifting type vehicle handler and a handling method, aiming to prevent obstacles in the parking space from hindering vehicle handling.

[0007] To this end, the present disclosure first provides a bilateral - thrust lifting type vehicle handler, including a vehicle body, and further including a pair of lifting mechanisms respectively connected to both ends of the vehicle body. The lifting mechanism includes:

[0008] A bottom frame, movably connected to the vehicle body;

[0009] A pair of lifting arms, connected to the bottom frame;

[0010] When the vehicle body moves below the vehicle, the bottom frames of the pair of lifting mechanisms move along the directions respectively close to the wheels at both ends of the vehicle until the pair of lifting arms lift the wheels of the vehicle.

[0011] According to the bilateral - thrust lifting type vehicle handler, the lifting arm is a wedge - shaped structure with a thickness at the front smaller than that at the rear.

[0012] According to the bilateral - thrust lifting type vehicle handler, the pair of lifting arms are connected to the bottom frame in a deployable or retractable manner.

[0013] According to the bilateral thrust lifting type vehicle carrier described above, the lifting arm is rotatably connected to the bottom frame, and the lifting mechanism further includes a driving assembly for driving the lifting arm to rotate. The driving assembly includes:

[0014] A sliding plate, movably connected to the bottom frame;

[0015] A connecting rod, one end of which is rotatably connected to the sliding plate and the other end of which is rotatably connected to the sliding plate;

[0016] A driver, connected to the sliding plate, for driving the lifting arm to rotate through the sliding plate and the connecting rod.

[0017] According to the bilateral thrust lifting type vehicle carrier described above, the lifting mechanism further includes a limiting block, which is connected to the bottom frame. When the driver drives the lifting arm to rotate until it abuts against the limiting block, the lifting arm is in an unfolded state for docking with the wheel.

[0018] According to the bilateral thrust lifting type vehicle carrier described above, the lifting arm is movably connected to the bottom frame along both sides of the length direction of the vehicle body; the lifting mechanism further includes a driving assembly for driving the lifting arm to extend and unfold or retract. The driving assembly includes:

[0019] A driving gear, rotatably connected to the bottom frame, the lifting arm is provided with teeth, and the driving gear meshes with a pair of the lifting arms;

[0020] A driver, connected to the driving gear, for synchronously driving a pair of the lifting arms to extend out of or retract into the bottom frame by driving the driving gear to rotate.

[0021] According to the bilateral thrust lifting type vehicle carrier described above, the lifting mechanism further includes a supporting wheel and a driving wheel rotatably connected to the bottom frame. The driving wheel is used for driving the bottom frame to move, and the supporting wheel is used for supporting the bottom frame.

[0022] According to the bilateral thrust lifting type vehicle carrier described above, it further includes a telescopic mechanism, which is connected to the vehicle body and has two ends connected to the bottom frame of the lifting mechanism, for synchronously pushing the lifting arms to move towards each other.

[0023] According to the bilateral thrust lifting type vehicle carrier described above, the telescopic mechanism includes:

[0024] A first telescopic arm, movably connected to the vehicle body along the telescopic direction;

[0025] A second telescopic arm, movably connected to the first telescopic arm along the telescopic direction;

[0026] A driving assembly, which is connected to the first telescopic arm and the second telescopic arm, is used to drive the first telescopic arm to move relative to the vehicle body and drive the second telescopic arm to move relative to the first telescopic arm.

[0027] In addition, the present disclosure also provides a bilateral thrust lifting type vehicle handling method, which is applicable to the bilateral thrust lifting type vehicle handler. The method includes the following steps:

[0028] After the vehicle handler moves below the vehicle, the bottom frames of the lifting mechanisms located at both ends of the vehicle body move towards the wheels;

[0029] The bottom frame drives the lifting arms to embed under the front wheels and rear wheels of the vehicle to lift the front wheels and rear wheels.

[0030] According to the bilateral thrust lifting type vehicle handling method, the bottom frames of the lifting mechanisms located at both ends of the vehicle body moving towards the wheels includes: the telescopic mechanism drives a pair of lifting arms of the lifting mechanisms to synchronously lift the wheels from the inner sides of the wheels.

[0031] Compared with the prior art, the above-mentioned bilateral thrust lifting type vehicle handler and handling method lift the front wheels and rear wheels by respectively lifting the front wheels and rear wheels from the inner sides of the wheels by two lifting arms of a pair of lifting mechanisms. During the moving process, the lifting arms only need to be inserted from one side of the wheels, so that it is not necessary to lift the wheels from both sides of the wheels, avoiding obstacles such as vehicle stoppers in the parking space from hindering the vehicle handling operation.

[0041] In order to more clearly understand the above - mentioned objects, features, and advantages of the present disclosure, the present disclosure will be described in detail below in conjunction with the drawings and specific embodiments. 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 in order 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. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present disclosure.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present disclosure belongs. The terms used in the present specification are only for the purpose of describing specific embodiments, and are not intended to limit the present disclosure.

[0043] In each embodiment, for the convenience of description rather than to limit the present disclosure, the term "connection" used in the specification and claims of the present patent application for the present disclosure is not limited to physical or mechanical connection, but may include electrical connection, whether direct or indirect. "Upper", "lower", "below", "left", "right", etc. are only used to represent relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship also changes accordingly.

[0044] Figure 1 is a schematic structural diagram of a bilateral - thrust lifting - type vehicle transporter in the retracted state, Figure 2 is a schematic structural diagram of a bilateral - thrust lifting - type vehicle transporter in the deployed state. As Figure 1 and 2As shown in the figure, the bilateral thrust lifting type vehicle transporter includes a vehicle body 10, a telescopic mechanism 20, and a pair of lifting mechanisms 30. The pair of lifting mechanisms 30 are respectively connected to both ends of the vehicle body 10. The telescopic mechanism 20 is used to drive the lifting mechanisms 30 to move towards the front wheels and rear wheels of the vehicle, lift the front wheels and rear wheels, so as to load the vehicle and realize the wheel handling operation. The "lifting" action in this application means that the lifting mechanism 30 extends from the driving surface where the wheel contacts the ground to the lower part of the wheel, so as to lift the wheel and carry the vehicle.

[0045] The vehicle body 10 is in a rectangular frame structure, provided with a plurality of traveling wheels 11 and corresponding drivers to drive the traveling wheels 11 to rotate. The overall width of the vehicle body 10 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 11 to carry the vehicle.

[0046] Figure 3 It is a schematic structural diagram of the lifting mechanism. As Figures 1-3 shown, the lifting mechanism 30 is used to lift the front wheels and rear wheels respectively from the inner sides of the vehicle tires at both ends of the vehicle body 10 after the whole vehicle transporter moves under the vehicle. Thus, the vehicle transporter can lift the front wheels and rear wheels of the vehicle, load the vehicle and move it to the destination to complete the vehicle handling operation.

[0047] In this embodiment, the lifting mechanism 30 includes a bottom frame 34, a lifting arm 31, a driving assembly, a supporting wheel 352, and a driving wheel 35. The lifting arm 31 is installed on the bottom frame 34 and is used to lift the wheel. The driving assembly is used to drive the lifting arm 31 to expand to one side in the driving direction of the wheel or retract to the position between the two wheels. The supporting wheel 352 and the driving wheel 35 are used to support and drive the movement of the bottom frame 34, and cooperate with the telescopic mechanism 20 to drive the lifting arm 31 to lift the wheel. In some other embodiments, the bottom frame 34 can also be separately towed and moved by the telescopic mechanism 20 or the driving wheel 35.

[0048] The bottom frame 34 is movably connected to the vehicle body 10. In this embodiment, the bottom frame 34 can be movably connected to the end position of the vehicle body 10 through a two-stage, three-stage or more-stage telescopic mechanism 20, so that the bottom frame 34 can move back and forth relative to the vehicle body 10 along the vehicle length direction. To improve the load-bearing capacity of the bottom frame 34, in this embodiment, the bottom frame 34 is also provided with supporting wheels 352 and driving wheels 35. The number of supporting wheels 352 is two, which are respectively rotatably arranged on both sides of the bottom frame 34. The driving wheel 35 is rotatably connected to the bottom frame 34 and is used to drive the bottom frame 34 to move relative to the vehicle body 10. In this embodiment, the bottom frame 34 is also provided with a battery pack 351 and a driver. The driver is connected to the driving wheel 35 and drives the driving wheel 35 to rotate under the power supply of the battery pack 351, so as to tow the bottom frame 34 to move back and forth relative to the vehicle body 10 under the support of the supporting wheels 352.

[0049] The lifting arm 31 can be connected to the bottom frame 34 in an expandable or foldable manner, and is used to lift the front and rear wheels of the vehicle. In this embodiment, the lifting arm 31 is a wedge-shaped structure with a front thickness less than a rear thickness to facilitate lifting the wheel. The thickness of the wedge-shaped opening at the front is smaller, while the thickness of the rear is larger, so that the wedge-shaped opening at the front can be convenient for cutting into the bottom of the wheel, and the rear can stop the wheel to prevent the wheel from escaping from the lifting arm 31. In this embodiment, the lifting arm 31 is rotatably connected to the bottom frame 34 and can be rotated 180° relative to the bottom frame 34. The lifting mechanism 30 also includes a limit block, which is connected to the two sides of the outer end of the bottom frame 34. When the driving assembly drives the lifting arm 31 to rotate to abut against the limit block, the lifting arm 31 is in an expanded state to dock the wheel. When the lifting arm 31 rotates to the expanded state, the wedge-shaped opening at the front is located at a position close to one side of the vehicle length direction (i.e., the inner side of the wheel). Preferably, the thickness of the rear part of the lifting arm 31 can be set larger to prevent the wheel from passing over the lifting arm 31; when the lifting arm 31 rotates 180° to the retracted state, the wedge-shaped openings of the pair of lifting arms 31 are arranged opposite to each other, and the lifting arm 31 is completely retracted to the width of the bottom frame 34 to avoid obstructing the vehicle carrier from passing under the vehicle. Those skilled in the art understand that the wedge-shaped lifting arm 31 is not necessary, and other shapes of lifting arms 31 can also cut under 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.

[0050] The driving assembly is used to drive the lifting arm 31 to rotate. In this embodiment, the driving assembly includes a sliding plate 33, a connecting rod 32 and a driver (not shown in the figure). The sliding plate 33 is movably connected to the bottom frame 34 along the traveling direction of the vehicle through a slide rail-slider structure. In this embodiment, the slide rail 331 is set on the bottom frame 34, and the sliding plate 33 is movably connected to the slide rail 331. The connecting rod 32 is a semi-"U"-shaped structure, one end of which is rotatably connected to the sliding plate 33, and the other end is rotatably connected to the lifting arm 31. Among them, the position of the connecting rod 32 connecting the lifting arm 31 deviates from the position of the connecting rod 32 connecting the bottom frame 34, so that when the sliding plate 33 moves, the lifting arm 31 can be driven to rotate relative to the bottom frame 34 through the connecting rod 32. The driver is connected to the sliding plate 33, and is used to drive the sliding plate 33 to move back and forth along the slide rail 331, thereby driving the lifting arm 31 to rotate through the connecting rod 32.

[0051] Figure 4 Schematic diagram of the structure of the telescopic mechanism 20. Figure 4As shown, the telescopic mechanism 20 is used to drive the lifting mechanism 30 to move relative to the vehicle body 10 closer to or farther away from the wheels. In this embodiment, the number of telescopic mechanisms 20 is two, and each telescopic mechanism 20 correspondingly drives a lifting mechanism 30 to move in the direction of approaching or departing from the wheels.

[0052] As an example, the telescopic mechanism 20 includes a first telescopic arm 21, a second telescopic arm 22, and a driving assembly. The telescopic motor 23 and the lead screw 24, the first telescopic arm 21 is movably connected to the vehicle body 10 along the telescopic direction, the second telescopic arm 22 is movably connected to the first telescopic arm 21 and is connected to the bottom frame 34. Specifically, a row of rollers 25 arranged along the telescopic direction are provided on both sides of the vehicle body 10, roller grooves 251 are provided on both sides of the first telescopic arm 21, and the first telescopic arm 21 realizes relative movement along the telescopic direction with respect to the vehicle body 10 by the rollers 25 being inserted into the roller grooves 251; similarly, roller grooves 251 are also provided on the outer sides of both sides of the first telescopic arm 21, rollers 25 are provided on both sides of the second telescopic arm 22, and the second telescopic arm 22 also realizes telescopic movement along the telescopic direction relative to the first telescopic arm 21 by the rollers 25 being inserted into the roller grooves 251. The driving assembly is connected to the first telescopic arm 21 and the second telescopic arm 22, and is used to drive the first telescopic arm 21 to move relative to the vehicle body 10, and to drive the second telescopic arm 22 to move relative to the first telescopic arm 21. In this embodiment, the driving assembly includes a telescopic motor 23 and a lead screw 24, and drives the first telescopic arm 21 and the second telescopic arm 22 to telescopically move through the telescopic motor 23 and the lead screw 24.

[0053] During operation, the first telescopic arm 21 moves relative to the vehicle body 10, and the second telescopic arm 22 moves relative to the first telescopic arm 21, driving the bottom frame 34 to move closer to or farther away from the wheels. In some other embodiments, the telescopic mechanism 20 can also be other mechanisms. For example, it can be a lead screw 24-nut structure to drive the bottom frame 34 to move, or it can be a hydraulic or pneumatic method to drive the bottom frame 34 to move. The present application does not limit this.

[0054] The above-mentioned bilateral thrust lifting type vehicle transporter is also configured with a controller and a memory. The memory stores programs and data for controlling the actions of the bilateral thrust lifting type vehicle transporter. After the controller reads the programs and data, it drives the bilateral thrust lifting type vehicle transporter to implement the following handling method. The method includes the following steps:

[0055] S1: After the vehicle transporter moves under the vehicle, the bottom frames 34 of the lifting mechanisms 30 at both ends of the vehicle body 10 move towards the wheels. In this step, the vehicle transporter generally moves to the central position between the front wheels and the rear wheels of the vehicle, and the lifting mechanisms 30 at both ends of the vehicle body 10 move towards the front wheels and the rear wheels synchronously. Before or during the movement, under the control of the controller, the sliding plate 33 drives the lifting arm 31 to rotate to the unfolded state through the connecting rod 32, and the wedge-shaped openings at the front parts of the lifting arms 31 face the front wheels and the rear wheels.

[0056] S2: The bottom frame 34 drives the lifting arm 31 to embed under the front wheels and the rear wheels of the vehicle to lift the front wheels and the rear wheels. In this step, the driver traction drive wheel 35 loads the bottom frame 34 to move along the direction close to the front wheels and the rear wheels, and the drive components of the telescopic mechanism 20 drive the lifting mechanisms 30 at both ends to move towards the front wheels and the rear wheels respectively, and lift the front wheels and the rear wheels respectively from the inner sides of the front wheels and the rear wheels, that is, the openings of the lifting arms 31 lift the front wheels from the rear sides of the front wheels and lift the rear wheels from the front sides of the rear wheels to lift the front wheels and the rear wheels. During the movement, the lifting arms 31 at both ends generally contact the front wheels and the rear wheels synchronously and lift the front wheels and the rear wheels synchronously. In this way, during the process of lifting the front wheels and the rear wheels, the vehicle body 10 is basically still located at the central position of the vehicle, the telescopic stroke of the telescopic mechanism 20 is short, and the thrust received is greater. When the lifting arm 31 lifts the vehicle, the thrust on the front wheels and the rear wheels will be more balanced.

[0057] Figure 5 is a schematic structural diagram of another lifting mechanism. As Figure 5 shown, different from the lifting mechanism 30 shown in Figure 3 and Figure 4 the lifting arm 31 of the lifting mechanism 30 shown in Figure 5 is movably and telescopically connected to the bottom frame 34. Specifically, the lifting arm 31 is movably connected to the bottom frame 34 along both sides of the length direction of the vehicle body 10. For example, it can be movably connected to the bottom frame 34 along both sides of the length direction of the vehicle through a slider-rail, a roller and a roller groove. The lifting mechanism 30 further includes a drive component for driving the telescopic movement of the lifting arm 31. As an example, the drive component includes a drive gear 36 and a driver (not shown in the figure). The drive gear 36 is rotatably connected to the bottom frame 34. A pair of the lifting arms 31 are arranged to move relatively, and teeth 311 are arranged along the length direction on the opposite sides. The drive gear 36 meshes with the teeth 311 of a pair of the lifting arms 31. The driver can be a motor, and the output shaft is connected to the drive gear 36. By driving the drive gear 36 to rotate, a pair of the lifting arms 31 are synchronously driven to extend or retract from the bottom frame 34. During operation, when the driver drives the drive gear 36 to rotate forward or backward, a pair of the lifting arms 31 can be synchronously driven to extend or retract and move from both sides of the bottom frame 34.

[0058] Those skilled in the art understand that the structures of the lifting mechanisms 30 at both ends of the vehicle body 10 can be the same or different. In some other embodiments, the lifting arms 31 of the lifting mechanism 30 can also be non-retractable and directly project out from both sides of the bottom frame 34 along the moving direction of the bottom frame 34. As an example, in the scenario where the bilateral thrust lifting type vehicle transporter enters below the vehicle from both sides of the vehicle, the lifting arms 31 do not need to adopt a retractable structure (rotary telescopic or linear telescopic structure). Those skilled in the art can set the specific structure of the lifting mechanism 30 according to needs.

[0059] In the above-mentioned bilateral thrust lifting type vehicle transporter and the transportation method, since the lifting arms 31 do not need to hold or clamp the tires from the front side of the front wheels and the rear side of the rear wheels, even if there are obstacles such as vehicle stoppers on the front side of the front wheels and the rear side of the rear wheels, it will not hinder the lifting arms 31 from lifting the wheels. Thus, it is possible to avoid the vehicle stoppers from hindering the vehicle transporter from transporting the vehicle. Moreover, the vehicle transporter can enter below the vehicle from the front and rear of the vehicle, or from both sides of the vehicle, and can adapt to various parking space scenarios.

[0060] In several specific embodiments provided by the present disclosure, for those skilled in the art, it is obvious that the present disclosure is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present disclosure, the present disclosure can be implemented in other specific forms.
