Description

Technical Field

[0001] The invention discloses a car mover, belonging to the technical field of car movers. Background Art

[0002] A car mover is a special driving device for moving unpowered RVs, trailers, trailers or yachts. When the vehicle itself has no driving force, the car mover can be used to drive the vehicle forward.

[0003] A car mover usually includes a frame, a hub motor and a tire fixed to the outer peripheral side of the hub motor. The hub motor includes a drive motor, a reduction mechanism connected to the drive motor and a wheel hub driven to rotate by the drive motor. However, during use, a traditional electric car mover requires an operator to manually operate a handle to control the moving direction of the car mover. The weight of the moved object is usually very large, and manual operation of the car mover requires a large external force, which makes the operator more laborious. Moreover, in the prior art, the drive motor and the reduction mechanism are respectively arranged on the left and right sides of the outer surface of the hub, which will cause the power transfer wheel to have a longer length in the axial direction of the hub. When the car mover turns, the area swept by the hub motor is larger. When the user manually operates the car mover, the distance to the car mover is close, and it is easy to collide with the car mover, posing a safety hazard. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem that a car mover is difficult to turn and is prone to collision with a user. For this purpose, a car mover is provided, which can automatically control the turning of the car mover through a steering mechanism, and the drive motor and the reduction mechanism are arranged in the wheel hub, thereby reducing the space occupied by the car mover and reducing the possibility of the car mover colliding with the user.

[0005] To solve the above technical problems, the present invention adopts the following technical solutions:

[0006] The transmission gear of the present invention is connected with the gear train of the transmission gear of the present invention, and the transmission gear of the present invention is connected with the gear train of the transmission gear of the transmission gear to the gear train of the transmission gear.

[0007] The beneficial effects of the present invention are:

[0008] The steering mechanism described in the present invention drives the transmission part through the steering motor to realize the relative rotation of the support rod and the frame. During use of the car mover, the support rod is fixedly connected to the object to be transported. When steering is required, the steering motor is started, and the support rod and the frame are relatively rotated through the action of the transmission part. Since the support rod and the object to be transported are fixed, the frame will drive the wheel hub motor to rotate, thereby realizing the steering of the car mover. No human operation is required during the steering process, making the operator more relaxed and labor-saving. At the same time, it can also enable the operator to stay away from the car moving support wheel, and the operator can maintain a safe distance from the moved object, thereby improving the safety of the use of the car moving support wheel; in addition, the wheel hub motor includes a wheel hub, and a left cover and a right cover are fixed on both sides of the wheel hub. The left cover, the right cover and the wheel hub are surrounded by a cavity, and the drive motor and the reduction mechanism are arranged between the left cover and the right cover, that is, the drive motor and the reduction mechanism are both in The wheel hub is provided with a controller, and the user can control the steering motor and the drive motor at the same time, so that the vehicle mover can steer while moving forward or backward, thereby reducing the risk of damage to the vehicle and the reducer.

[0009] Preferably, the transmission member includes a worm gear and a worm screw that mesh with each other, the worm gear is connected to the output shaft of the steering motor, the worm gear is fixedly connected to the support rod, and the support rod rotates synchronously with the worm gear to achieve relative rotation between the frame and the support rod. Adopting the above-mentioned technical solution, the steering mechanism can accurately control the relative rotation angle of the support rod and the frame through the worm gear and the worm screw, thereby achieving precise steering of the entire car mover, improving the operator's control over the car mover, and reducing the possibility of collision of the object to be transported; in addition, the worm gear is connected to the steering motor, and the transmission coordination of the worm gear and the worm screw has a self-locking characteristic. The steering motor can control the rotation of the worm gear through the worm gear, and when the steering motor is not working, power cannot be transmitted from the worm gear to the worm gear, that is, the support rod cannot control the worm gear to drive the worm gear to rotate, thereby preventing the possibility of accidental steering of the car mover, helping to improve the stability of the car mover during operation, and also improving the safety of the use of the car mover; secondly, the structure of the worm gear and the worm screw transmission system is relatively simple, easy to disassemble and assemble, and convenient for daily maintenance and care, which helps to extend the service life of the car mover and reduce maintenance costs.

[0010] Preferably, the steering mechanism includes an upper box body and a lower box body that are spliced together, and an installation cavity for the rotation of the worm gear and the worm is formed between the upper box body and the lower box body. The lower box body is fixed to the top of the frame, and the bottom end of the support rod passes through the upper box body and extends into the installation cavity, and is fixedly connected to the worm gear. With the above-mentioned technical solution, the splicing of the upper box body and the lower box body simplifies the assembly process of the steering mechanism, making it easier to access the internal components during manufacturing and maintenance. When the worm gear, worm gear and other components need to be repaired or replaced, the upper box body can be conveniently disassembled without removing the entire steering mechanism from the frame. In addition, the support rod is directly connected to the turbine, which can more effectively transmit the steering drive force, reduce the steering error caused by loose connection or wear, and make the steering of the car mover more accurate and reliable.

[0011] Preferably, the driving motor includes a casing, the casing has a connecting portion at the end near the left side cover, a through hole is provided in the middle of the left side cover, the connecting portion extends into the through hole and rotates with the inner wall of the through hole, and the connecting portion is fixedly connected to the frame.

[0012] Preferably, the housing of the drive motor and the housing of the reduction mechanism are integrally formed. By adopting the aforementioned technical solution, the drive motor and the reduction mechanism share the same housing, which allows for tighter installation of the drive motor and the reduction mechanism, further reducing their volume and achieving a high degree of integration between the drive motor and the reduction mechanism, making the internal structure of the wheel hub more compact. Furthermore, the integral structure of the drive motor housing and the reduction mechanism ensures a stable and reliable connection between the drive motor and the reduction mechanism, reducing the possibility of loosening due to vibration, and making the transmission connection between the drive motor and the reduction mechanism even tighter and more reliable.

[0013] Preferably, the drive motor includes a casing, a stator fixed to the inner wall of the casing, and a rotor for cooperating with the stator. One side of the casing is provided with a convex ring extending toward the right side cover. The convex ring serves as the housing of the reduction mechanism. One end of the rotor extends into the convex ring and is transmission-connected to the reduction mechanism.

[0014] Preferably, the right side cover is provided with a sealing convex ring that rotatably engages with the convex ring. The right side cover is also provided with a transmission portion that extends into the convex ring. The transmission portion is fixedly connected to the movable ring gear and is driven for rotation by the movable ring gear. Adopting this technical solution, using the right side cover to seal the convex ring eliminates the need for a housing at the end of the reduction mechanism, further reducing the volume occupied by the reduction mechanism and improving the compactness of the wheel hub's internal structure. It also serves to position the reduction mechanism's internal structure, ensuring stable and reliable assembly of the internal structure.

[0015] Preferably, the sun gear and the output shaft of the drive motor are integrally formed. By adopting the aforementioned technical solution, the sun gear and the output shaft of the drive motor are integrally formed, which significantly reduces the outer diameter of the sun gear, thereby reducing the volume of the reduction mechanism, thereby keeping the reduction mechanism compact and lightweight. Furthermore, since the sun gear is part of the output shaft of the drive motor, the installation of the sun gear can be omitted, which helps to simplify the assembly process and reduce the cumulative error caused by multiple installation steps. Furthermore, it also ensures that the drive motor stably drives the sun gear to rotate, thereby improving the transmission accuracy and reliability of the sun gear and planetary gears.

[0016] Preferably, the frame includes a connecting base, with downwardly extending connecting plates disposed on either side of the connecting base. The two connecting plates are rotatably engaged with the left and right covers, respectively. The connection between the connecting plates and the connecting base is provided with a plurality of indentations forming reinforcing ribs. The aforementioned technical solution increases the rigidity of the connection between the connecting base and the connecting plates, thereby increasing the load capacity of the connecting base, enabling the vehicle mover to carry heavier objects, while also reducing the likelihood of deformation or damage to the connecting base.

[0017] Preferably, the support rod includes an inner rod and an outer rod, the outer rod is slidingly connected to the inner rod, a screw rod is rotatably connected to the outer rod, and a nut is provided at the end of the inner rod that cooperates with the screw rod. The screw rod and the nut rotate relative to each other to realize relative sliding of the inner rod and the outer rod.

[0026] The following is an explanation and description of the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention. However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0028] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0029] like Figures 1 to 5 As shown, this embodiment shows a car mover, including a frame 1, a hub motor 2 for driving the frame 1 to move, and a support rod 4 at the top of the frame 1 and rotatably connected to the frame 1. The hub motor 2 includes a wheel hub 21 with a tire 26 on the outer circumference and a drive motor 24 for driving the wheel hub 21 to rotate. A left cover 22 and a right cover 23 are fixed on both sides of the wheel hub 21. A steering mechanism 3 is provided between the frame 1 and the support rod 4. The steering mechanism 3 includes a steering motor 31 and a transmission member connected to the support rod 4. The steering motor 31 is fixed relative to the frame 1 and drives the support rod 4 to rotate relative to the frame 1 through the transmission member. A controller for controlling the steering motor 31 and the drive motor 24 is provided on the frame 1. The output shaft of the drive motor 24 is connected to the reduction mechanism 25. The drive motor 24 and the reduction mechanism 25 are both located between the left cover 22 and the right cover 23. The reduction mechanism 25 includes a sun gear driven by the output shaft, planetary gears 252 meshing with the sun gear, and a fixed ring gear 253 and a movable ring gear 254 meshing with the outer circumference of the planetary gear 252. The fixed ring gear 253 remains fixed relative to the drive motor 24, and the movable ring gear 254 is fixedly connected to the right cover 23. The planetary gear 252 drives the movable ring gear 254 to rotate to drive the right cover 23 to rotate.

[0030] The steering mechanism 3 described in this embodiment drives the transmission part through the steering motor 31 to realize the relative rotation of the support rod 4 and the frame 1. During the use of the car mover, the support rod 4 is fixedly connected to the object to be transported. When steering is required, the steering motor 31 is started, and the support rod 4 and the frame 1 are rotated relative to each other through the action of the transmission part. Since the support rod 4 is fixed to the object to be transported, the frame 1 will drive the hub motor 2 to rotate, thereby realizing the steering of the car mover. No human operation is required during the steering process, making the operator more relaxed and labor-saving. At the same time, it can also enable the operator to stay away from the car moving support wheel, and the operator can maintain a safe distance from the moved object, thereby improving the safety of the use of the car moving support wheel; in addition, the hub motor 2 includes a wheel hub 21, and a left cover 22 and a right cover 23 are fixed on both sides of the wheel hub 21. The left cover 22, the right cover 23 and the wheel hub 21 are surrounded by a cavity, and the drive motor 24 and the reduction mechanism 25 are arranged between the left cover 22 and the right cover 23, that is, the drive motor 24 and the reduction mechanism 25 are both in the cavity. The wheel hub 21 is provided with a plurality of control wheels 24 and 25, and the wheel hub 21 is provided with a plurality of control wheels 24 and 25. The wheel hub 21 is provided with a plurality of control wheels 24 and 25. The control wheels 24 and 25 are provided with a plurality of control wheels 24 and 25. The control wheels 24 and 25 are provided with a plurality of control wheels 24 and 25. The control wheels 24 and 25 are provided with a plurality of control wheels 24 and 25.

[0031] like Figure 2 and Figure 5As shown, the steering mechanism 3 in this embodiment also includes a worm gear box 32 fixed to the top of the frame 1, and the transmission member includes a worm wheel 34 and a worm 33. The steering motor 31 is fixedly connected to the worm gear box 32 through a reduction box. The worm gear box 32 includes an upper box body 321 and a lower box body 322 that are spliced with each other. A mounting cavity for the worm wheel 34 and the worm 33 to rotate is formed between the upper box body 321 and the lower box body 322. The lower box body 322 is fixedly mounted on the upper surface of the frame 1. The top of the upper box body 321 is provided with a through hole for the support rod 4 to extend into, and the bottom end of the support rod 4 extends into the mounting cavity. It is fixedly connected to the worm gear 34 in the worm gear box 32. The splicing of the upper box body 321 and the lower box body 322 simplifies the assembly process of the steering mechanism 3, making it easier to access the internal components during manufacturing and maintenance. When the worm gear 34, worm 33 and other parts need to be repaired or replaced, the upper box body 321 can be easily disassembled without removing the entire steering mechanism 3 from the frame 1; in addition, the support rod 4 is directly connected to the turbine, which can more effectively transmit the steering drive force, reduce the steering error caused by loose connection or wear, and make the steering of the car mover more accurate and reliable.

[0032] like Figure 2 As shown, the worm wheel 34 and the worm 33 in this embodiment are both placed horizontally, and the worm wheel 34 is sleeved on the outer surface of the support rod 4. The bottom end of the support rod 4 extends into the lower box body 322 and is rotatably connected to the lower box body 322 through a bearing. In addition, the through-hole of the upper box body 321 is also provided with a bearing connected to the support rod 4. When the car mover needs to turn, the steering motor 31 is started, and the steering motor 31 drives the worm 33 to rotate through the reduction gear box. The worm 33 cooperates with the worm wheel 34 to drive the support rod 4 to rotate. Since the support rod 4 is connected to the object to be transferred, the support rod 4 is fixed relative to the object to be transferred, so the rotation of the frame 1 relative to the support rod 4 is realized, thereby realizing the steering of the car mover.

[0033] like Figure 2 and Figure 3As shown, the wheel hub 21 described in this embodiment is annular as a whole, and the outer peripheral side of the wheel hub 21 is covered with a tire 26. The wheel hub 21 contacts the ground through the tire 26. The tire 26 can buffer the wheel hub 21, reduce the bump amplitude during the power transfer wheel process, and make the movement of the power transfer wheel more stable. At the same time, it can also protect the wheel hub 21, reduce the possibility of deformation of the wheel hub 21, and help to extend the service life of the power transfer wheel; in addition, the two sides of the wheel hub 21 are respectively fixed with a left cover 22 and a right cover 23, and the wheel hub 21, the left cover 22 and the right cover 23 are surrounded to form a accommodating cavity, and the drive motor 24 and the reduction mechanism 25 are arranged between the left cover 22 and the right cover 23, wherein one end of the drive motor 24 is rotatably connected to the left cover 22, and the other end is transmission-connected to the reduction mechanism 25, and the output end of the reduction mechanism 25 is transmission-connected to the right cover 23, and the drive motor 24 drives the right cover 23 to rotate through the reduction mechanism 25, and the wheel hub 21 rotates as the right cover 23 rotates, thereby realizing the movement of the power transfer wheel.

[0034] The driving motor 24 in this embodiment includes a housing 241, a stator 243 fixed to the inner wall of the housing 241, and a rotor 242 for cooperating with the stator 243, wherein the housing 241 has a connecting portion 244 at the end close to the left cover 22, and the connecting portion 244 is rotatably connected to the left cover 22. The housing 241 has a convex ring 251 extending toward the right cover 23 at the end close to the right cover 23. The reduction mechanism 25 is installed in the convex ring 251, and one end of the rotor 242 extends into the convex ring 251 and is transmission-connected to the reduction mechanism 25. In this embodiment, the convex ring 251 and the housing 241 are an integrated structure. By installing the reduction mechanism 25 in the convex ring 251, By making the drive motor 24 and the reduction mechanism 25 share the same housing 241, the installation of the drive motor 24 and the reduction mechanism 25 can be made tighter, the volume of the drive motor 24 and the reduction mechanism 25 can be further reduced, the drive motor 24 and the reduction mechanism 25 can be highly integrated, and the structure inside the wheel hub 21 can be made more compact; in addition, the housing 241 of the drive motor 24 and the box body of the reduction mechanism 25 are an integrated structure, so that the connection between the drive motor 24 and the reduction mechanism 25 can remain stable and reliable, reducing the possibility of the drive motor 24 and the reduction mechanism 25 becoming loose due to vibration, and making the transmission connection between the drive motor 24 and the reduction mechanism 25 tighter and more reliable.

[0035] Of course, it is understandable that in other embodiments, the housing 241 and the protruding ring 251 may also be a split structure.

[0036] like Figure 1 and Figure 2As shown, in this embodiment, the two sides of the frame 1 are provided with connecting plates 12 extending downward, and the frame 1 is in an inverted U shape as a whole. The drive motor 24 is rotatably connected between the two connecting plates 12. The left cover 22 of the wheel hub 21 is provided with a through hole. The connecting portion 244 of the housing 241 extends into the through hole and rotates with the inner wall of the through hole through a bearing. The connecting portion 244 is fixedly connected to one of the connecting plates 12. The right cover 23 forms a seal with the convex ring 251 and rotates with the convex ring 251. The right cover 23 is provided with a transmission portion 231 extending into the convex ring 251. The transmission portion 231 is transmission-connected to the reduction mechanism 25 and driven to rotate by the reduction mechanism 25. The outer side of the right cover 23 is rotatably engaged with the other connecting plate 12 through a bearing. By using the right cover 23 to seal the convex ring 251, the housing at the end of the reduction mechanism 25 can be omitted, further reducing the volume occupied by the reduction mechanism 25, and improving the compactness of the internal structure of the wheel hub 21. At the same time, it can also play a positioning role for the internal structure of the reduction mechanism 25, so that the assembly of the internal structure of the reduction mechanism 25 remains stable and reliable.

[0037] like Figure 3 As shown, the reduction mechanism 25 in this embodiment includes a sun gear driven by an output shaft, planetary gears 252 meshing with the sun gear, and a fixed ring gear 253 and a movable ring gear 254 meshing with the outer circumference of the planetary gear 252. The fixed ring gear 253 remains fixed relative to the drive motor 24, and the movable ring gear 254 is fixedly connected to the right side cover 23. The planetary gear 252 drives the movable ring gear 254 to rotate to drive the right side cover 23 to rotate. The fixed ring gear 253 and the movable ring gear 254 are used to reduce the output shaft of the drive motor 24, which can provide a higher reduction ratio, thereby being able to output a greater torque to the wheel hub 21, so that the wheel hub 21 can carry a greater weight, which helps to improve the wheel The scope of use of the hub 21; in addition, the fixed ring gear 253 and the movable ring gear 254 share the same planetary gear 252, which can avoid reverse transmission of power, prevent the reverse input of power into the drive motor 24 and cause damage to the drive motor 24, and can protect the drive motor 24, which helps to extend the service life of the drive motor 24; secondly, when the drive motor 24 is turned off, since the power cannot be transmitted in the opposite direction, the reduction mechanism 25 can have a self-locking effect, preventing the hub 21 from still rotating after the drive motor 24 is turned off, ensuring the stability of the power transfer wheel after parking, avoiding automatic landslide and other phenomena, and making the use of the power transfer wheel safer.

[0038] In order to improve the transmission accuracy between the sun gear and the output shaft, the sun gear and the output shaft of the drive motor 24 in this embodiment are an integrated structure, that is, the outer surface of the output shaft end is cut to form a plurality of teeth, so that it can maintain engagement with multiple planetary gears 252. The sun gear and the output shaft of the drive motor 24 are set to an integrated structure, which can greatly reduce the outer diameter of the sun gear, and thus reduce the volume of the reduction mechanism 25 to keep the reduction mechanism 25 small and light; in addition, the sun gear is part of the output shaft of the drive motor 24, which can eliminate the installation of the sun gear, help simplify the assembly process, and reduce the cumulative error caused by multiple installation steps; secondly, it can also ensure that the drive motor 24 stably drives the sun gear to rotate, thereby improving the transmission accuracy and transmission reliability of the sun gear and the planetary gear 252.

[0039] like Figure 1 and Figure 4 As shown, the support rod 4 in this embodiment includes an inner rod 41 and an outer rod 42. The outer rod 42 is slidably connected to the inner rod 41, and a screw rod 421 is rotatably connected to the outer rod 42. The end of the inner rod 41 is provided with a nut 411 that cooperates with the screw rod 421. The screw rod 421 and the nut 411 rotate relative to each other to realize the relative sliding of the inner rod 41 and the outer rod 42; in addition, in order to facilitate the rotation of the screw rod 421, the top of the screw rod 421 in this embodiment passes through the top of the outer rod 42 and is fixedly connected to a handle 44. The operator can realize the rotation of the screw rod 421 by rotating the handle 44; secondly, the outer surface of the outer rod 42 in this embodiment is fixedly installed with a clamp 43, and the support rod 4 fixes the moved object through the clamp 43. After that, the operator controls the outer rod 42 and the inner rod 41 to slide relative to each other by rotating the handle 44, so that the support rod 4 gradually extends. When the moved object is lifted to the specified height, the wheel hub 21 can be controlled to start to achieve the car moving effect.

[0040] In addition, in order to make the use of the car moving support wheel more intelligent, the frame 1 in this embodiment is provided with a mounting seat, and a controller is fixed in the mounting seat. The controller is used to control the steering motor 31 and the drive motor 24. At the same time, the controller is equipped with a remote control. The operator can remotely control the car mover through the remote control. While the car mover is moving forward or backward, the operator can also control the car mover to turn left or right at the same time, so that the car mover can turn simultaneously during the forward and backward processes, thereby improving the intelligence of the car mover. At the same time, it can also keep the operator away from the operating range of the car mover, which can significantly improve the safety of the use of the car mover.

[0041] The support rod 4 described in this embodiment can be fixed to the heavy object, and then can drive the heavy object for transportation, so that the vehicle moving support wheel can be used in fields such as moving non-powered RVs and trailers. Of course, it can be understood that in other embodiments, multiple vehicle moving support wheels can also be combined to form a multi-drive transfer cart, which can be applied to the field of logistics and transportation, and move and transport items during warehousing and distribution. Of course, it can be understood that in other embodiments, the vehicle moving support wheel is applied to the vehicle field, and the vehicle moving support wheel is installed on the vehicle. The power transfer wheel of this embodiment has a simple structure and can be directly driven, thereby eliminating complex structures such as the chassis.

[0042] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art will understand that the present invention includes, but is not limited to, the contents described in the drawings and the above specific embodiments. Any modifications that do not deviate from the functional and structural principles of the present invention are intended to be included within the scope of the claims.
