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.

It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

In one embodiment, as shown in fig. 1 to 11, a self-locking vehicle handling system 100 includes a frame 10, and a traveling mechanism 30 and a clamping arm mechanism 40 mounted on the frame 10.

The vehicle transportation system 100 moves to a parking position of the vehicle through the traveling mechanism 30, each clamping arm mechanism 40 is matched with a corresponding wheel position, and each clamping arm mechanism 40 clamps a corresponding wheel and supports the vehicle in a matched manner, so that the vehicle transportation system 100 can transport the vehicle. The carrying process of parking and taking out vehicles is realized.

As shown in fig. 8 to 10, the clamping arm mechanism 40 includes:

a lifting base 42 slidably mounted with respect to the base 11;

a first driving mechanism 43 mounted on the base 11 for driving the lifting base 42 to move;

a pair of movable arms 41 which are matched with each other to clamp the wheel, wherein each movable arm 41 rotates on the lifting seat 42;

the second drive mechanism 44 is independently disposed on each movable arm 41, and the second drive mechanism 44 is attached to the lifter base 42 and drives the corresponding movable arm 41 to rotate by the worm gear mechanism 47.

The two movable arms 41 are substantially rod-shaped and have corresponding strength, in an initial state, the two movable arms 41 are opposite in extending direction relative to the rotating axial direction of the two movable arms 41, namely the two movable arms are arranged substantially in a collinear manner, and in operation, the second driving mechanism 44 drives the two movable arms 41 to rotate around the axis of the two movable arms 41 until the two movable arms 41 clamp the vehicle wheel, and at the moment, the two movable arms 41 support the bottom of the vehicle wheel substantially side by side.

After the two movable arms 41 are clamped, the first driving mechanism 43 drives the lifting seat 42 and the movable arms 41 to lift, so that the height of the two movable arms 41 from the ground can be increased by 40mm or more, the vehicle is completely separated from the ground, and a larger space is kept; when the vehicle conveying system 100 meets the condition of uneven ground or potholes during the process of conveying the vehicle, the movable arm 41 and the vehicle wheels can not touch the ground, and the safety of equipment and the safety of the vehicle are effectively protected.

The ground is a support surface for supporting the vehicle handling system 100 and should be understood in a broad sense, i.e., a support surface capable of being provided for the vehicle handling system 100 to travel on may be understood to be a ground surface, such as a floor or other support structure.

The worm and gear mechanism 47 can not only transmit the power of the second driving mechanism 44 to the two movable arms 41, but also can realize the self-locking of each movable arm 41 when each movable arm 41 moves to a preset position, and does not need to additionally arrange a locking mechanism for each movable arm 41 or avoid the locking by braking the second driving mechanism 44.

The first driving mechanism 43 mainly drives the lifting seat 42 to make a linear reciprocating motion along the height direction of the system, and in order to realize the basic function, a motor, an air cylinder, a hydraulic cylinder or even a manual driving component can be selected in the prior art, and when the motion mode directly output by the first driving mechanism 43 is inconsistent with the motion mode of the lifting seat 42, the motion mode can be steered and transmitted by using a proper transmission component.

The second driving mechanism 44 is mainly used to drive the movable arm 41 to rotate, and in order to implement its basic function, a motor, an air cylinder, a hydraulic cylinder or even a manual driving component may be selected in the prior art, and when the motion mode directly output by the second driving mechanism 44 is inconsistent with the motion mode of the movable arm 41, a proper transmission component may be used to steer and transmit the motion mode.

In another embodiment, the movable arm 41 is rotatably mounted at the bottom of the lifting seat 42, and the rotation axis of the movable arm 41 extends along the height direction of the system, so as to reduce the height of the movable arm 41 when the movable arm is not lifted (or is considered as an initial state) as much as possible, so as to adapt to wheels with different sizes.

In another embodiment, in the worm gear mechanism 47, the worm 471 is directly linked with the second driving mechanism 44, the worm wheel 472 is fixed to the rotating shaft of the movable arm 41, the worm wheel 472 is engaged with the worm 471, and the worm wheel 472 is coaxially arranged with the rotating shaft of the movable arm 41.

In another embodiment, as shown in fig. 1 and 2, the frame 10 includes a plurality of (e.g., two) relatively moving frames, and the clamping arm mechanisms 40 of all the frames 10 cooperate to support the vehicle, and in order to ensure the balance and stability of the vehicle handling system 100, the two frames 10 relatively moving are connected by the telescopic mechanism 50 for guiding the trend of the relative movement.

The two frame bodies 10 can move towards or away from each other within the stroke range of the telescopic mechanism 50. The provision of the telescopic mechanism 50 enables the entire vehicle handling system 100 to be balanced and stable. The telescoping mechanism 50 enables the relative distance between the two frame bodies 10 to be adjustable, and ensures that the vehicle handling system 100 is integrated and integrally and uniformly operated.

Before the vehicle carrying system 100 carries the vehicle, the two frame bodies 10 move in opposite directions or in reverse directions under the driving of the traveling mechanism 30 respectively, and then the relative distance between the clamping arm mechanisms 40 arranged on the two frame bodies 10 is adjusted, so that when the vehicle carrying system 100 carries the vehicles with different wheelbases, the clamping arm mechanisms 40 are not needed to carry out independent distance adjustment, the overall dimension of the vehicle carrying system 100 can be effectively reduced, and meanwhile, the requirement of the vehicle carrying system 100 on the dimension of the channel can be effectively reduced.

Wherein, telescopic machanism 50 can be single part, and telescopic machanism 50 can also be fixed with a support body 10 with two support body 10 clearance fit that are connected simultaneously (can take place relative displacement), and with another support body 10 clearance fit, telescopic machanism 50 and at least one support body 10 can take place relative motion to the change of two support body 10 intervals of adaptation.

When the telescopic mechanism 50 is a single component, the telescopic mechanism 50 and the two frame bodies 10 can be fixedly connected, and at the moment, the telescopic mechanism 50 can deform and adapt to the change of the distance between the two frame bodies 10 through the deformation.

The shape of the telescopic mechanism 50 is not limited strictly, for example, when it is a rod, at least one end of the rod can slide along the corresponding frame 10, or the middle part (middle position or position near the middle) of the rod itself can be bent or deformed to change the length of the two ends of the rod. Of course, if the telescoping mechanism 50 is an assembly, it can be connected to the two frames 10 in the above-mentioned ways, and when the distance between the two frames 10 is changed, the relative movement between different components in the assembly can be used.

For example, the telescoping mechanism 50 is a multi-link mechanism in which at least two rods are capable of moving relative to each other to change the overall span of the multi-link mechanism, i.e., to change the length of the telescoping mechanism 50.

Since the two frame bodies 10 are provided with the traveling mechanism 30, the telescoping mechanism 50 adopts a passive mode, i.e., the two frame bodies 10 actively move, and the telescoping mechanism 50 passively adapts to the change of the distance between the two frame bodies 10. The telescoping mechanism 50 can also be provided with power to actively drive the two frame bodies 10 to move relatively.

In another embodiment, as shown in fig. 3 to 5, the vehicle handling system 100 has opposite system length and system width directions, and the vehicle handling system 100 has an overhead region 101 penetrating in the system length direction, and the racks 10 are sequentially arranged in the system length direction.

Wherein the system length (i.e., X-direction in fig. 3) and the system width (i.e., Y-direction in fig. 3) are perpendicular to each other.

The vehicle handling system 100 moves to the parked position of the vehicle until the vehicle is within the overhead area 101. At this point, the vehicle handling system 100 does not have to enter from under the vehicle chassis, avoiding the height of the vehicle handling system 100 being limited to the height of the vehicle chassis from the ground.

In another embodiment, in order to ensure the balance and stability of the vehicle handling system 100, each rack 10 includes a pair of bases 11, the same pair of bases 11 are disposed on two sides of the overhead area 101 along the width direction of the system and are connected and fixed to each other by a connecting beam 20 passing over the overhead area 101, each base 11 is configured with a traveling mechanism 30 and a clamping arm mechanism 40, and the clamping arm mechanisms 40 on each base 11 cooperate with each other to support a vehicle located in the overhead area 101.

In another embodiment, the bases 11 on the same side of the hollow space 101 in the width direction of the system are connected by the telescopic mechanism 50, and the distance between the two shelves 10 along the length direction of the system can be adjusted and changed by the guidance of the telescopic mechanism 50.

In another embodiment, as shown in fig. 6 and 7, the first base 111 and the second base 112 are respectively connected to the telescopic mechanism 50, the telescopic mechanism 50 at least includes a guide 51, one end of the guide 51 is slidably engaged with the first base 111, and the other end is slidably or fixedly engaged with the second base 112.

The first base 111 and/or the second base 112 are provided with sliding grooves which are matched with the guide members 51 to limit the movement tendency of each other, for example, the guide members 51 can be inserted into the sliding grooves and can move along the sliding grooves. Similarly, the guiding element 51 may be provided with a sliding slot, and each base is provided with a guiding element matching with the sliding slot.

In the present embodiment, both ends of the guide 51 are slidably engaged with the first base 111 and the second base 112, respectively, and the maximum distance between the two frame bodies 10 can be increased as much as possible when the space occupied by the first base 111 and the second base 112 is constant.

In another embodiment, the first base 111 and the second base 112 are respectively mounted with guide wheels 52 in a row along the length direction of the system, and the guide members 51 are respectively engaged with the guide wheels 52 on the corresponding side bases 11.

Each guide wheel 52 is rotatably connected to the corresponding side base 11, and the rotation axes of each guide wheel 52 on the same base 11 are arranged in parallel.

The guiding wheel 52 can be a driven wheel, and at least one guiding wheel 52 can be provided with power according to requirements, for example, a gear-rack engagement or the like is adopted to drive the guiding element 51 to move so as to change the distance between the two frame bodies 10.

In order to limit the trend of the relative movement between the guide member 51 and the guide wheels 52 in the row and the smoothness of the relative movement, a support groove (for example, the guide member 51 has a C-shaped cross section) extending along the length of the system may be formed on the guide member 51, the support groove has an upper side wall and a lower side wall opposite to each other along the height direction of the system, the guide wheels 52 in the same row may be both attached to a certain side wall (for example, the upper side wall), or the guide wheels 52 in the same row may be divided into two parts, wherein the top of one part of the guide wheels 52 is attached to the upper side wall, and the bottom and the lower side wall are arranged with a gap; the bottom of the other part of the guide wheel 52 is attached to the lower side wall, and the top is arranged with a gap from the upper side wall.

In the present embodiment, the number of the guide wheels 52 on the same base 11 is 2 to 10, for example, 3, 4 or 5, but of course, in other embodiments, the number of the guide wheels 52 on the same base 11 may be larger, and the number of the guide wheels 52 may be adjusted according to the length of the chute.

In another embodiment, the vehicle handling system 100 further comprises at least one of the following stop mechanisms:

the first limiting mechanism 53 acts between the two frame bodies 10 to limit the minimum distance between the two frame bodies 10 in a close state;

the second limiting mechanism 54 acts between the two frame bodies 10 to limit the maximum distance between the two frame bodies 10 in the extending state.

The first limiting mechanisms 53 are arranged at two ends of the guide piece 51, and limiting steps matched with the first limiting mechanisms 53 are arranged in the sliding grooves to prevent the guide piece 51 from being separated from the sliding grooves.

The second limiting mechanism 54 is disposed in the sliding groove. In the present embodiment, the second limit mechanism 54 is a stopper attached to the base 11 and capable of abutting against the guide 51 to limit the movement of the guide 51 within the chute. Of course, in other embodiments, the second limiting mechanism 54 may be the bottom wall of the chute.

In another embodiment, in order to escape the connection beam 20 from the vehicle in the overhead space 101, the connection beam 20 includes an elevated piece 21 and a cross piece 22; the raising member 21 extends upward from the base 11; the cross member 22 is connected between the elevations 21 of the same pair of bases 11.

In the same support body 10, the number of the raising members 21 is two, the two raising members 21 are respectively located on the two bases 11, and both ends of the crossing member 22 are respectively connected with the two raising members 21.

In another embodiment, the raising members 21 extend obliquely upward from the base 11, and the top ends of the raising members 21 on the two frame bodies 10 are close to each other, which can reduce the space occupied by the vehicle handling system 100 during the shutdown.

In another embodiment, the two bodies 10 have a close state adjacent to each other and an extended state away from each other, and only one of the two bodies 10 walks or both walks at the same time when the state is changed.

When the vehicle carrying system 100 is in a standby state, the two racks 10 are close to each other; when the vehicle handling system 100 needs to handle a vehicle, the extended state is adjusted according to the wheelbase length of the vehicle, so that the distance between the two frame bodies 10 is adapted to the wheelbase length.

The close state is a state in which the two frame bodies 10 abut against each other, or a state in which the minimum distance between the two frame bodies 10 is located under the restriction of the telescoping mechanism 50.

The extended state is relative to the closed state. It can be understood that the two frame bodies 10 are relatively moved from the close state to increase the distance, i.e. in the extending state. For example, the limit position of the extended state is that the telescoping mechanism 50 limits the maximum distance between the two lower frame bodies 10.

In another embodiment, the vehicle handling system 100 is configured with a detection unit for detecting the wheel position of the vehicle and a control unit; the control unit is electrically connected with the detection unit and is used for receiving the signal from the detection unit and driving the travelling mechanism 30 to enable the clamping arm mechanism 40 to be matched with the corresponding wheel position.

The wheel position of the vehicle is detected by the detection unit, the detected wheel position signal is sent to the control unit, and the control unit receives and processes the wheel position signal and drives the two frame bodies 10 to move relatively according to the processed signal, so that each clamping arm mechanism 40 is matched with the corresponding wheel position. The detection unit may be a laser, a photosensitive device, a photoelectric switch, or the like.

Further, each frame 10 supplies power to the traveling mechanism 30, the clamping arm mechanism 40, the control unit and the detection unit through an external power supply or a battery power supply carried by the frame.

The traveling mechanism 30 and the clamping arm mechanism 40 on each frame body are respectively in communication connection with the detection unit and the control unit.

The detecting unit may be installed on each frame 10, i.e. may move with the vehicle handling system 100, may be externally installed relative to the vehicle handling system 100, and may be installed on a vehicle moving path generally, and detect the wheel position of the vehicle when the vehicle passes through, and the detecting unit may be configured with a corresponding processing function, and convert the relative positions of the front and rear wheels into wheel base information and then transmit the wheel base information to the control unit, or may directly transmit the relative positions of the front and rear wheels to the control unit, and the control unit performs processing conversion.

In one embodiment, the detecting unit is installed on one side of each frame 10 facing the empty space 101, and when a vehicle enters the empty space 101, the detecting unit can obtain a wheel position signal.

The detection unit and the control unit can adopt wired or wireless communication.

During wireless communication, the detection unit is provided with a wireless transmitting module, the control unit is provided with a wireless receiving module, the wireless transmitting module transmits the detected signal, and the wireless receiving module can receive the signal.

In another embodiment, the detection unit is external to the vehicle handling system 100 and wireless communication is used between the detection unit and the control unit.

For example, the detection unit is installed at the entrance of a garage, and when a vehicle enters the entrance of the garage, the detection unit can acquire wheel position signals.

The traveling mechanism 30 and the clamping arm mechanism 40 on each frame body are respectively in communication connection with the detection unit and the control unit.

In another embodiment, the contact portion of the running gear 30 and the ground in each frame 10 forms a supporting region, the force center of the frame 10 when supporting the vehicle is directed to the supporting region along the gravity direction, and the telescoping mechanism 50 only plays a role of connection and does not bear torque.

In each frame body 10, there may be a plurality of sets of running gear 30, and generally at least two sets of running gear 30 are distributed on both sides of the overhead area, so that the contact parts of the running gear 30 and the ground are arranged at intervals, and the contact parts of the plurality of positions enclose a so-called support domain.

Everywhere, there may be an area with a certain area, or a line segment (e.g. the road wheel is a rigid wheel), or even a point (e.g. the road wheel is a rigid sphere);

the plurality of contact portions as a whole may be an area or a line segment.

For example, two sets of running gears 30 of the same frame 10 are distributed on both sides of the vehicle when the vehicle handling system 100 handles the vehicle.

Each set of the traveling mechanism 30 adopts a single-wheel structure or a parallel double-wheel structure, at this time, if the deformation of the tire is neglected, the contact positions of the traveling mechanism 30 and the ground are collinear in the same frame body 10, a line segment formed by connecting two contact positions which are farthest away in each frame body 10 is used as a support domain, and the projection of the stress center along the gravity direction is positioned on the support domain.

Referring to fig. 8, the force center points in the direction Q to the support field, which corresponds to the point M.

Since the traveling wheels 31 may be deformed according to the weight of the frame body 10 and the vehicle body, the area of the contact portion is changed without affecting the determination of the support region.

For another example, more than two sets of traveling mechanisms 30 are provided on the same frame 10, or all the traveling wheels 31 in the same traveling mechanism 30 are not arranged coaxially, at this time, the contact portion between the traveling mechanism 30 and the ground is a support region surrounded by three or more points and having a certain area, and the projection of the force center along the gravity direction is located in the support region. In the preferred embodiment, two sets of traveling mechanisms 30 are provided on the same frame 10, when the vehicle handling system 100 handles a vehicle, the two sets of traveling mechanisms 30 on the same frame 10 are distributed on two sides of the vehicle, each set of traveling mechanism 30 adopts a single-wheel or side-by-side double-wheel structure, and when the vehicle handling system 100 moves forward or backward, all the traveling wheels 31 on the same frame 10 are coaxially arranged.

In another embodiment, the movable arms 41 are spaced apart and side-by-side in the working position of the support vehicle, and the axis of travel of each frame 10 is located between the movable arms 41 in the same pair that grip the same wheel in the direction of gravity.

Because the same pair of movable arms 41 are generally symmetrically clamped at two sides of the lower half part of the same wheel, the middle position of the same pair of movable arms 41 basically corresponds to the stress center of the frame body in the gravity direction, and the projection of the stress center of the frame body in the structure can correspond to the walking wheel axis.

When the vehicle handling system 100 faces vehicles with different wheelbases in the using process, the projection of the stress center of the vehicle handling system 100 falls into the position of the support domain; meanwhile, the structural arrangement of the vehicle handling system 100 is more compact, and the overall dimension of the vehicle handling system 100 is effectively controlled.

In another embodiment, in order to lower the center of gravity of the frame 10 from affecting the center of force of the frame 10 when supporting a vehicle, the center of gravity of each frame 10 itself is directed in the direction of gravity toward the support area.

In another embodiment, the coupling beam 20 is installed to swing or slide with respect to the frame 10, wherein the swing axis is parallel to the width direction of the system, and the sliding direction is parallel to the length direction of the width direction of the system.

By adjusting the coupling beam 20, changing the relative position between the coupling beam 20 and the frame 10 may serve to adjust the center of gravity position of the base 11, or adapt the vehicle handling system 100 to vehicles of different heights.

The gravity center position of the base 11 is adjusted, so that whether the vehicle is unloaded or carried, the gravity center position of each frame body 10 is directly above the support domain, the overturning tendency of the frame body is reduced, the torque applied to the telescopic mechanism 50 is avoided, the telescopic mechanism 50 can be simplified as much as possible, and the strength requirement of the telescopic mechanism 50 is reduced.

The change in the position of the center of gravity of the base 11 can be detected by a sensing device (for example, a gyroscope or the like can be used); when the posture of the frame body 10 is changed (overturned), the sensing device detects a change signal of the gravity center position and sends the change signal to the control unit, and the control unit receives and processes the change signal of the gravity center position and drives the connecting beam 20 to change the position of the frame body 10 according to the processed signal, so that the posture of the connecting beam on the frame body is changed, the posture change trend of the frame body is compensated, and the gravity center position of each frame body 10 is ensured to be positioned right above the support domain.

In another embodiment, the connecting beam 20 is height adjustable relative to the frame 10 in order to further accommodate the vehicle handling system 100 with vehicles of different heights.

In one embodiment, as shown in fig. 12, there is further provided a vehicle handling method, where the vehicle handling system of each of the above embodiments is adopted, the vehicle handling method includes:

acquiring wheel base information of a vehicle;

adjusting the spacing of each frame body in the vehicle carrying system according to the wheel base information to enable the relative position of each clamping arm mechanism to be matched with the wheel base information;

aiming at the vehicles in the overhead area, driving each clamping arm mechanism to respectively clamp and support the corresponding vehicle wheel in a state that each clamping arm mechanism is matched with the wheel;

the vehicle handling system moves a handling vehicle as a whole.

When the wheel base information of the vehicle is obtained, the wheel base information can be obtained by using a detection unit which is preset at the moving path of the vehicle; in the process that the vehicle enters the empty space, the detection units arranged on the frame bodies of the vehicle conveying system can be utilized.

Before the vehicle is carried, each clamping arm mechanism is matched with the position of a wheel, the control unit needs to correspondingly adjust the distance between the two frame bodies according to the wheel base information, and the wheel base information can be obtained before the vehicle enters the overhead area, so that the distance between the frame bodies can be adjusted in advance, and can also be adjusted after the vehicle enters the empty area.

The adjustment mode of each support body interval can be single support body motion or two support body linkages, for example the running gear of control unit to support body sends drive signal, and when running gear worked, control unit also compares support body interval and wheel base information according to its amount of exercise in real time and whether matches, also can additionally set up the ranging unit certainly, gathers support body interval in real time and sends to control unit.

The distance between the frame bodies can be adjusted according to the wheel base information, but during actual transportation, each clamping arm mechanism should be matched with the actual position of the wheel, so that the relative position of the whole vehicle transportation system and the vehicle needs to be adjusted, that is, the relative position of the vehicle in the overhead area is further confirmed, this point can utilize the prior art, for example, a sensing element which is arranged in or out of the frame body is used for knowing the relative position of the vehicle, and after the relative position of the vehicle is confirmed, each clamping arm mechanism is in a state of being matched with the position of the wheel. If the distance between the frame bodies is adjusted when the vehicle enters the frame empty area, the actual positions of the clamping arm mechanisms and the wheels can be matched when the distance is adjusted.

Then, the control unit drives the movable arms in each clamping arm mechanism to rotate, the movable arms of the same pair are in a parallel spaced state and are just positioned at two sides of the bottom of the corresponding wheel, then the control unit drives each pair of movable arms to synchronously ascend to lift the vehicle to be separated from the ground, and the clearance height between the bottom of the wheel and the ground can be increased to 20mm or more according to requirements.

According to the preset carrying destination, the control unit drives the traveling mechanism to drive the vehicle carrying system to integrally move, and the carrying of the vehicle is realized.

The vehicle handling system 100 of the present application is structurally modified to avoid having to enter from under the vehicle chassis, thereby avoiding the height of the vehicle handling system 100 being limited by the height of the vehicle chassis from the ground.
