Description

Technical Field

[0001] This application relates to the field of vehicle mobile equipment technology, and in particular to a foldable vehicle mover and its control method. Background Technology

[0002] A car mover is a specialized tool used to move vehicles in confined spaces. It is widely used in parking lots, auto repair shops, 4S stores, showrooms, and other scenarios. It can enable lateral movement and turning of vehicles, solving problems such as vehicles being parked too tightly or being unable to reverse out of the parking space.

[0003] Most existing car movers are fixed structures, with their frames, support arms, and wheels rigidly connected, making them impossible to fold and store. This results in car movers taking up a significant amount of space when not in use, making them inconvenient for warehousing, transportation, and carrying. Furthermore, assembling and packaging car movers requires considerable packaging space. To save space, manufacturers often disassemble the car movers before shipping, requiring users to assemble them themselves, which causes significant inconvenience.

[0004] To address the aforementioned issues, there is currently no solution for a car mover that can both move cars and fold away for storage when not in use to reduce space occupation. Summary of the Invention

[0005] This application aims to address at least one of the technical problems existing in the related art. To this end, this application proposes a folding car mover and its control method, which can be unfolded to support and move vehicles when in use, and folded away for storage when not in use to significantly reduce the space occupied.

[0006] A folding car mover according to a first aspect embodiment of this application includes:

[0007] Main crossbeam;

[0008] Secondary crossbeam;

[0009] At least two support arms are respectively mounted on the main crossbeam and the secondary crossbeam to support the vehicle wheels;

[0010] The main crossbeam and the secondary crossbeam are connected by a first hinge structure, so that the secondary crossbeam can rotate relative to the main crossbeam between a first position and a second position.

[0011] The support arm is connected to the corresponding crossbeam via a second hinge structure, so that the support arm can rotate relative to the corresponding crossbeam between a third position and a fourth position.

[0012] The embodiments of this application can produce the following technical effects: through the first hinge structure between the main crossbeam and the secondary crossbeam and the second hinge structure between the support arm and the corresponding crossbeam, the vehicle mover can switch between an unfolded state and a folded state. When not in use, the secondary crossbeam and the support arm can be folded and stored, greatly reducing the space occupied and facilitating warehousing, transportation and carrying.

[0013] According to one embodiment provided in this application, when the secondary crossbeam rotates relative to the main crossbeam to the first position, the main crossbeam and the secondary crossbeam are connected end to end in the longitudinal direction and extend in the same straight line direction to form an unfolded state; when the secondary crossbeam rotates relative to the main crossbeam to the second position, the secondary crossbeam folds back and overlaps with the side of the main crossbeam to form a folded state.

[0014] Understandably, in the unfolded state, the main crossbeam and the secondary crossbeam are connected end to end to form a straight beam frame, which together constitutes the full width of the frame to support the wheels on both sides; in the folded state, the secondary crossbeam rotates around the hinge to the side of the main crossbeam and overlaps with it, thereby significantly reducing the overall width of the frame.

[0015] According to one embodiment provided in this application, when the support arm is rotated to the third position, the support arm extends outward perpendicular to the corresponding crossbeam to support the vehicle wheels; when the support arm is rotated to the fourth position, the support arm is folded and stored under the corresponding crossbeam.

[0016] Understandably, when the support arm is extended, it extends outward perpendicular to the crossbeam, forming a U-shaped or H-shaped support structure together with the main crossbeam and the secondary crossbeam to support the vehicle wheels; when the support arm is folded, it rotates to the bottom of the crossbeam, making full use of the space under the crossbeam for storage without increasing the overall thickness.

[0017] According to one embodiment provided in this application, the first hinge structure includes a hinge, and the second hinge structure includes a rotating pin.

[0018] Understandably, the hinge enables in-plane rotation between the main crossbeam and the secondary crossbeam, allowing the secondary crossbeam to rotate relative to the main crossbeam in the horizontal plane; the swivel pin enables out-of-plane rotation between the support arm and the crossbeam, allowing the support arm to rotate relative to the crossbeam in the vertical plane. The two hinge methods are adapted to different folding direction requirements.

[0019] According to one embodiment provided in this application, it further includes a first locking mechanism and a second locking mechanism; the first locking mechanism is disposed between the main crossbeam and the secondary crossbeam, and is used to lock the secondary crossbeam to the main crossbeam when the secondary crossbeam rotates to the first position, so as to prevent the secondary crossbeam from rotating relative to the main crossbeam; the second locking mechanism is disposed between the support arm and the corresponding crossbeam, and is used to lock the support arm to the corresponding crossbeam when the support arm rotates to the third position, so as to prevent the support arm from rotating relative to the corresponding crossbeam.

[0020] Understandably, the first and second locking mechanisms lock when the frame and support arm are deployed, respectively, to ensure that all parts of the vehicle mover remain fixed during operation and will not rotate unexpectedly due to force, thus ensuring the load-bearing capacity and structural stability of the vehicle mover and guaranteeing operational safety.

[0021] According to one embodiment of this application, a folding locking mechanism is also included, which includes a hook and a pin. The hook is disposed on one of the support arms, and the pin is disposed on the other support arm. When the sub-beam rotates to the second position and the support arm rotates to the fourth position, the hook hooks the pin to maintain the folded state of the folding car mover.

[0022] Understandably, the folding locking mechanism secures the components together when the vehicle mover is in the folded state, preventing it from being accidentally unfolded during storage or transportation, ensuring the reliable maintenance of the folded state, and facilitating handling and storage.

[0023] According to one embodiment of this application, the main crossbeam and / or the secondary crossbeam are provided with a guide mechanism, and the support arm is slidably disposed on the guide mechanism; the guide mechanism extends along the length direction of the main crossbeam and / or the secondary crossbeam, and the distance between adjacent support arms is adjusted when the support arm slides along the guide mechanism.

[0024] Understandably, the guide mechanism allows the support arm to slide along the length of the crossbeam, thereby adjusting the distance between the two support arms and enabling the vehicle mover to adapt to different vehicle track widths, thus exhibiting good versatility and applicability.

[0025] According to one embodiment of this application, a driving mechanism is further included. The driving mechanism is disposed on the main crossbeam and / or the secondary crossbeam and connected to the support arm for driving the support arm to slide along the guide mechanism. The driving mechanism includes a lead screw transmission mechanism or a hydraulic transmission mechanism. The lead screw transmission mechanism includes a lead screw and a lead screw nut. The lead screw is rotatably disposed on the main crossbeam and / or the secondary crossbeam, and the lead screw nut is connected to the support arm. The hydraulic transmission mechanism includes a hydraulic cylinder and a quick-connect coupling. The hydraulic cylinder is disposed on the main crossbeam and / or the secondary crossbeam, and the piston rod of the hydraulic cylinder is connected to the support arm.

[0026] Understandably, by driving the support arm to slide along the guide mechanism through screw drive or hydraulic drive, the operator can lift and lower the wheels by turning the handle or operating the hydraulic station without complicated operating steps. Screw drive is suitable for scenarios with electric drills or no external power source, while hydraulic drive is suitable for scenarios with electric or manual hydraulic stations or scenarios that require simultaneous lifting of multiple car movers. The two can be flexibly selected according to actual needs.

[0027] According to one embodiment provided in this application, the support arm includes an arc-shaped bending member, the middle part of which protrudes downward and is provided with a roller, the roller being used to contact the vehicle wheel, and the bottom of both ends of the arc-shaped bending member is provided with casters, and at least one end is used to connect to the corresponding crossbeam.

[0028] Understandably, the middle of the bow-shaped bending component protrudes downwards, and the roller passes through the middle protrusion. When the vehicle mover lifts the wheel, the roller contacts the wheel, reducing frictional resistance and avoiding damage to the tire. The omnidirectional wheels at the bottom of both ends of the bow-shaped bending component allow the vehicle mover to move flexibly in all directions after lifting the vehicle, making it easy to move or turn the vehicle to the target position.

[0029] A method for operating a folding car mover according to a second aspect embodiment of this application, applied to the folding car mover described in any one of the first aspect embodiments, includes the following steps:

[0030] The secondary crossbeam is rotated relative to the main crossbeam to the first position, and the support arm is rotated relative to the corresponding crossbeam to the third position, so that the folding car mover is in the unfolded state;

[0031] Adjust the support arms to both sides of the vehicle wheels;

[0032] Drive the support arm to move along the length of the main crossbeam and / or the secondary crossbeam, so that the support arm clamps and lifts the vehicle wheel;

[0033] Move the vehicle to the target location;

[0034] Drive the support arm to move in the opposite direction, causing the vehicle wheels to descend to the ground;

[0035] The support arm is rotated to the fourth position relative to the corresponding crossbeam, and the secondary crossbeam is rotated to the second position relative to the main crossbeam, so that the folding car mover is in a folded state.

[0036] The control method of the second aspect of this application can achieve the following technical effect: by first unfolding the vehicle mover, then lifting the wheels, moving the vehicle, lowering the wheels, and finally folding and storing it, the operator can quickly unfold and complete the vehicle moving operation when needed, and quickly fold and store it after the operation is completed. The operation steps are simple and clear, and a single person can complete the whole process.

[0037] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0052] The following is combined Figures 1 to 11 This application describes the folding car mover and its operation method.

[0053] A folding car mover according to a first aspect embodiment of this application includes:

[0054] Main crossbeam 1;

[0055] Secondary crossbeam 2;

[0056] At least two support arms 3 are respectively disposed on the main crossbeam 1 and the secondary crossbeam 2 for supporting the vehicle wheels;

[0057] The main crossbeam 1 and the secondary crossbeam 2 are connected by a first hinge structure, so that the secondary crossbeam 2 can rotate relative to the main crossbeam 1 between a first position and a second position;

[0058] The support arm 3 is connected to the corresponding crossbeam via a second hinge structure, so that the support arm 3 can rotate relative to the corresponding crossbeam between a third position and a fourth position.

[0059] The embodiments of this application can produce the following technical effects: through the first hinge structure between the main crossbeam 1 and the secondary crossbeam 2 and the second hinge structure between the support arm 3 and the corresponding crossbeam, the vehicle mover can switch between the unfolded state and the folded state. When not in use, the secondary crossbeam 2 and the support arm 3 can be folded and stored, which greatly reduces the space occupied and facilitates warehousing, transportation and carrying.

[0060] In such Figure 1 and Figure 2 In the illustrated embodiment, the main crossbeam 1 and the secondary crossbeam 2 are connected by a hinge 7. The secondary crossbeam 2 can rotate in the horizontal plane relative to the main crossbeam 1 about the hinge 7. Figure 1 As shown, when the vehicle mover is in the deployed state, the secondary crossbeam 2 rotates relative to the main crossbeam 1 to the first position, and the main crossbeam 1 and the secondary crossbeam 2 are connected end-to-end longitudinally and extend in the same straight direction. Figure 2 As shown, when the car mover is in the folded state, the secondary crossbeam 2 rotates to the second position relative to the main crossbeam 1, and the secondary crossbeam 2 folds back and overlaps with the side of the main crossbeam 1.

[0061] The support arm 3 is connected to the corresponding crossbeam (main crossbeam 1 or secondary crossbeam 2) via a rotating pin 8. The support arm 3 can rotate relative to the corresponding crossbeam in a vertical plane around the rotating pin 8. Figure 1 As shown, when the vehicle mover is in the extended state, the support arm 3 rotates to the third position, extending outward perpendicularly to the corresponding crossbeam to support the vehicle wheels. Figure 2 As shown, when the car mover is in the folded state, the support arm 3 rotates to the fourth position and is folded and stored under the corresponding crossbeam.

[0062] According to one embodiment provided in this application, the system further includes a first locking mechanism 9 and a second locking mechanism 10. The first locking mechanism 9 is disposed between the main crossbeam 1 and the secondary crossbeam 2, and is used to lock the secondary crossbeam 2 to the main crossbeam 1 when the secondary crossbeam 2 rotates to a first position, thereby preventing the secondary crossbeam 2 from rotating relative to the main crossbeam 1. The second locking mechanism 10 is disposed between the support arm 3 and the corresponding crossbeam, and is used to lock the support arm 3 to the corresponding crossbeam when the support arm 3 rotates to a third position, thereby preventing the support arm 3 from rotating relative to the corresponding crossbeam.

[0063] Understandably, the first locking mechanism 9 and the second locking mechanism 10 lock when the frame is deployed and the support arm 3 is deployed, respectively, to ensure that all parts of the vehicle mover remain fixed during operation and will not rotate unexpectedly due to force, thus ensuring the load-bearing capacity and structural stability of the vehicle mover and ensuring operational safety.

[0064] According to one embodiment provided in this application, a folding locking mechanism 11 is also included. For example... Figure 8As shown, the folding locking mechanism 11 includes a hook 12 and a pin 13. The hook 12 is disposed on one of the support arms 3, and the pin 13 is disposed on the other support arm 3. The hook 12 hooks the pin 13 when the sub-beam 2 rotates to the second position and the support arm 3 rotates to the fourth position, so as to keep the folding car mover in the folded state.

[0065] Understandably, the folding locking mechanism 11 secures the components together when the vehicle mover is in the folded state, preventing the vehicle mover from being accidentally unfolded during storage or transportation, ensuring the reliable maintenance of the folded state, and facilitating handling and storage.

[0066] According to one embodiment provided in this application, such as Figure 5 As shown, the main crossbeam 1 and / or the secondary crossbeam 2 are provided with a guide mechanism 14, and the support arm 3 is slidably mounted on the guide mechanism 14. The guide mechanism 14 extends along the length direction of the main crossbeam 1 and / or the secondary crossbeam 2, and the support arm 3 adjusts the spacing between adjacent support arms 3 when sliding along the guide mechanism 14. Specifically, a nylon pad 22 is provided between the guide mechanism 14 and the support arm 3. The nylon pad 22 is used to reduce friction and noise when the support arm 3 slides along the guide mechanism 14, and to prevent direct wear between metal parts.

[0067] Understandably, the guide mechanism 14 enables the support arm 3 to slide along the length of the crossbeam, thereby adjusting the distance between the two support arms 3, so that the vehicle mover can adapt to the wheel track of different vehicles and has good versatility and applicability.

[0068] According to one embodiment of this application, a drive mechanism is further included. The drive mechanism is disposed on the main crossbeam 1 and / or the secondary crossbeam 2 and connected to the support arm 3, for driving the support arm 3 to slide along the guide mechanism 14. The drive mechanism includes a lead screw transmission mechanism or a hydraulic transmission mechanism.

[0069] The lead screw drive mechanism includes a lead screw 15 and a lead screw nut 16. The lead screw 15 is rotatably mounted on the main crossbeam 1 and / or the secondary crossbeam 2 via a lead screw bearing 21. The lead screw bearing 21 is fixed to the crossbeam and provides rotational support for the lead screw 15. The lead screw nut 16 is connected to the support arm 3. A handle 17 is provided at the end of the lead screw 15. The operator can rotate the handle 17 to drive the lead screw 15 to rotate, and the lead screw nut 16 drives the support arm 3 to slide along the guide mechanism 14. The operator can also use a power drill with a socket to drive the lead screw 15 to rotate.

[0070] Understandably, by driving the support arm 3 to slide along the guide mechanism 14 through the screw drive, the operator can lift and lower the wheel by turning the handle 17. No complicated operation is required, making it suitable for scenarios without an external power source.

[0071] According to other embodiments of this application, the drive mechanism may also be a hydraulic transmission mechanism. For example... Figure 9 As shown, the hydraulic transmission mechanism includes a hydraulic cylinder 18 and a quick-connect coupling 19. The hydraulic cylinder 18 is mounted on the main crossbeam 1 and / or the secondary crossbeam 2, and the piston rod of the hydraulic cylinder 18 is connected to the support arm 3. When oil is supplied to the hydraulic cylinder 18 through the quick-connect coupling 19, the piston rod drives the support arm 3 to slide along the guide mechanism 14. Furthermore, four wheel lifters can share the same hydraulic station, or the four hydraulic cylinders can be connected in parallel using hydraulic hoses. When high-pressure hydraulic oil is supplied to the hydraulic cylinders, synchronous lifting of the four wheels can be achieved. Figure 9 and Figure 11 As shown

[0072] Understandably, hydraulic transmission is suitable for scenarios requiring labor-saving operation or simultaneous lifting of multiple vehicle movers. Operators can provide power to the hydraulic cylinders via electric or manual hydraulic stations, making it flexible and convenient to use.

[0073] According to one embodiment provided in this application, such as Figure 7 As shown, the support arm 3 includes an arc-shaped bent member 4, with a downward-protruding center and a roller 5 passing through it. The roller 5 is used to contact the vehicle wheels. Universal wheels 6 are provided at the bottom of both ends of the arc-shaped bent member 4, and at least one end is used to connect to the corresponding crossbeam.

[0074] Understandably, the middle of the bow-shaped bending component 4 protrudes downwards, and the roller 5 passes through the protrusion. When the vehicle mover lifts the wheel, the roller 5 contacts the wheel, reducing frictional resistance and preventing tire damage. The swivel wheels 6 at the bottom of both ends of the bow-shaped bending component 4 allow the vehicle mover to move flexibly in all directions after lifting the vehicle, facilitating the horizontal or vertical movement of the vehicle to the target location.

[0075] According to other embodiments of this application, the lead screw transmission mechanism can also be electrically driven, that is, a drive motor is installed at the end of the lead screw 15, and the lead screw 15 is rotated by the motor to realize the electric sliding of the support arm 3. The hydraulic transmission mechanism can also use a manual hydraulic pump as a power source, so that it can still be used normally in the absence of power. The vehicle mover can be configured with different numbers of support arms 3 according to actual needs. For example, four support arms 3 can be used to correspond to the four wheels of the vehicle, or two support arms 3 can be used to correspond to the two wheels on the same axle.

[0076] The working principle and technical effects of the foldable car mover described in this application will be further explained below in conjunction with its usage process.

[0077] A method for operating a folding car mover according to a second aspect embodiment of this application includes the following steps:

[0078] Rotate the secondary crossbeam 2 relative to the main crossbeam 1 to the first position, and rotate the support arm 3 relative to the corresponding crossbeam to the third position, so that the folding car mover is in the unfolded state;

[0079] Adjust support arm 3 to both sides of the vehicle wheels;

[0080] Drive the support arm 3 to move along the length of the main crossbeam 1 and / or the secondary crossbeam 2, so that the roller 5 on the support arm 3 is in contact with and clamped to the tire surface, and continue to drive the support arm 3 to move until the wheel is completely off the ground and the roller 5 bears the entire weight of the vehicle, thereby achieving lifting;

[0081] Move the vehicle to the target location;

[0082] Drive support arm 3 to move in the opposite direction, causing the vehicle wheels to descend to the ground;

[0083] Rotate the support arm 3 relative to the corresponding crossbeam to the fourth position, and rotate the secondary crossbeam 2 relative to the main crossbeam 1 to the second position, so that the folding car mover is in the folded state.

[0084] Specifically, when the car mover is needed, first remove it from its stored state. Unhook the hook 12 of the folding locking mechanism 11, disengaging it from the pin 13. Rotate the secondary crossbeam 2 relative to the main crossbeam 1 to the first position, where the main crossbeam 1 and secondary crossbeam 2 are connected end-to-end longitudinally and extend in the same straight line. Simultaneously rotate the support arm 3 relative to the corresponding crossbeam to the third position, where the support arm 3 extends outward perpendicular to the corresponding crossbeam. Lock the first locking mechanism 9 and the second locking mechanism 10 respectively, keeping the car mover in its unfolded state.

[0085] Then, according to the wheel track of the vehicle to be moved, pull out the positioning pin on the guide mechanism 14 (not shown in the figure), slide the support arm 3 along the guide mechanism 14, adjust the support arm 3 to the position corresponding to the vehicle wheel, and then insert the positioning pin back to fix the guide mechanism 14.

[0086] Next, operate the drive mechanism. If a screw drive is used, the operator turns the handle 17 or uses a hand drill to drive the screw 15 to rotate. The screw nut 16 drives the support arm 3 to move towards the center along the guide mechanism 14, so that the roller 5 on the support arm 3 contacts and clamps the wheel. Continuing to drive the screw 15 will lift the wheel. If a hydraulic drive is used, connect the quick-connect connector 19 of the hydraulic station to the quick-connect connector 19 on the hydraulic cylinder 18, start the hydraulic station to supply oil to the hydraulic cylinder 18, and the piston rod pushes out to drive the support arm 3 to move towards the center to lift the wheel.

[0087] Once all four wheels are raised, the operator moves the vehicle to the target location by pushing and pulling the vehicle mover using handle 20.

[0088] When it is necessary to lower the wheels, operate the drive mechanism in reverse. In the screw drive mode, turn the handle 17 or the electric drill in reverse to drive the screw 15 to rotate in the opposite direction. The support arm 3 moves outward along the guide mechanism 14, and the wheels descend to the ground under gravity. In the hydraulic drive mode, connect the quick-connect connector 19 of the hydraulic station to the quick-connect connector 19 on the hydraulic cylinder 18, loosen the oil release nut of the hydraulic station, and under the weight of the vehicle, the support arm 3 moves outward to compress the piston rod of the hydraulic cylinder 18, and the wheels descend to the ground.

[0089] After the vehicle relocation operation is completed, pull out the first locking mechanism 9 and the second locking mechanism 10, and rotate the support arm 3 relative to the corresponding crossbeam to the fourth position, so that the support arm 3 is folded and stored under the corresponding crossbeam. Then rotate the secondary crossbeam 2 relative to the main crossbeam 1 to the second position, so that the secondary crossbeam 2 is folded back and overlapped to the side of the main crossbeam 1. Finally, hook the hook 12 onto the pin 13 to keep it folded, which is convenient for storage and transportation.

[0090] Compared with traditional fixed-structure car movers, the folding car mover and its operation method of this application have the following advantages:

[0091] First, the foldable design significantly reduces storage space: the main crossbeam 1 and the secondary crossbeam 2 adopt a hinged structure, and the support arm 3 and the crossbeam adopt a hinged structure, which can achieve double folding. When not in use, the space occupied can be reduced by more than 60%, which is convenient for warehousing, transportation and carrying, and solves the problem of traditional car movers being large and inconvenient to store.

[0092] Second, multiple locking mechanisms ensure a stable and reliable structure: through the coordinated action of the first locking mechanism 9, the second locking mechanism 10, and the folding locking mechanism 11, each hinge is firmly locked when the vehicle is unfolded, ensuring the load-bearing capacity and structural stability of the vehicle mover, preventing structural loosening during operation, and ensuring operational safety.

[0093] Third, it is easy to operate and highly practical: the spacing of the support arm can be quickly adjusted by inserting and removing the positioning pin to adapt to different wheel tracks, and the wheels can be lifted and lowered by turning the handle or operating the hydraulic station. No complicated tools are required, and one person can complete the operation. It is suitable for use in various scenarios such as parking lots, auto repair shops, 4S stores, and showrooms.

[0094] Fourth, wide adaptability: The drive mechanism can adopt either screw drive or hydraulic drive, and users can choose flexibly according to actual needs and usage scenarios; screw drive is suitable for scenarios without external power source, while hydraulic drive is suitable for scenarios that require labor-saving operation or simultaneous lifting of multiple car movers.

[0095] The device embodiments described above are merely illustrative, and some or all of the structures can be selected to achieve the purpose of this embodiment according to actual needs. Those skilled in the art can understand and implement these embodiments without any creative effort.

[0096] Finally, it should be noted that the above embodiments are only used to illustrate this application and are not intended to limit this application. Although this application has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of this application do not depart from the spirit and scope of the technical solutions of this application and should be covered within the scope of the claims of this application.
