Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of parking equipment, in particular to a telescopic comb tooth carrier. BACKGROUND

[0002] The vehicle transfer technology in the automatic garage is divided into two forms of the platform plate transfer technology and the no-platform plate transfer technology, and the comb tooth type no-platform plate transfer technology is widely applied due to its high comprehensive performance. The first generation of comb tooth transfer technology was introduced in the 1980s and entered commercialization, which is called COMPARK system. It was invented by Giovanni Valli, an Italian industrial inventor and EU registered engineer. Since 1997, the system has been introduced to Shanghai, Shenzhen, Guangzhou and other places in China.

[0003] The existing comb tooth carrier technology is old, the structure is complex, and it is difficult to maintain and repair. With the increase of the service life, failures occur from time to time. For example, the telescopic and lifting of the comb tooth are not flexible enough or appear to be stuck, which affects the normal use and increases the use cost. Therefore, it is necessary to update and optimize the structure to reduce the occurrence of failures and improve the use efficiency. CONTENT OF THE INVENTION

[0004] In order to solve the existing problems of the comb tooth carrier, simplify the structure, reduce the occurrence of failures and improve the use efficiency, the present application provides a telescopic comb tooth carrier.

[0005] The telescopic comb tooth carrier provided by the present application adopts the following technical scheme.

[0006] A telescopic comb tooth carrier comprises:

[0007] A walking chassis comprises a chassis and a walking device arranged on the chassis, and the walking device is used for supporting and driving the chassis to walk;

[0008] A lifting comb tooth device comprises a lifting mechanism and a comb tooth mechanism, and the lifting mechanism is arranged on the chassis and used for driving the lifting of the comb tooth mechanism;

[0009] The lifting mechanism includes a lifting frame with two lifting supports spaced apart at both ends. Lifting support wheels are rotatably mounted on the two lifting supports. The lifting mechanism also includes spiral lifting wheels located at both ends of the lifting frame. Two arc-shaped ramp grooves are formed around the outer side of each spiral lifting wheel. The spiral lifting wheels are rotatably supported on a base frame and rotated by a lifting power assembly. The lifting support wheels are located within the arc-shaped ramp grooves. The lifting mechanism also includes a limiting assembly, which includes a limiting cylinder mounted on the base frame. The limiting cylinder moves a limiting rod. A limiting groove is formed at the bottom of each spiral lifting wheel. When the spiral lifting wheel rotates and raises the lifting frame to its highest position, the limiting rod inserts into the limiting groove.

[0010] The comb mechanism includes a first comb mechanism, which includes a first left comb frame and a first right comb frame. The first left comb frame and the first right comb frame are slidably mounted on the lifting frame along the left and right width direction of the base frame. The first left comb frame and the first right comb frame are slidably mounted by a first comb power component mounted on the lifting frame.

[0011] By adopting the above technical solution, the chassis can support and drive the entire telescopic comb transporter to move, thus achieving transportation. The comb mechanism can carry the vehicle, and the lifting support wheel can roll along the inclined surface of the arc-shaped ramp, thereby driving the lifting support wheel and the lifting frame to rise and fall, and in turn driving the comb frame to rise and fall. When the spiral lifting wheel rotates and drives the lifting frame to rise to the highest position, the limit cylinder drives the limit rod to move, so that the limit rod inserts into the limit groove, causing the spiral lifting wheel to stop rotating, and the lifting frame to complete the rising operation. This ensures that the rising of the lifting mechanism and the comb mechanism is limited, improving the safety, stability and accuracy of the rising. Furthermore, under the drive of the first comb power component, the first left comb frame and the first right comb frame slide, realizing the extension and retraction of the comb.

[0012] Optionally, the lifting mechanism further includes a detection component, which includes an upper detection ramp and a lower detection ramp disposed at the top and bottom of the end of the lifting bracket. A detection support plate is disposed on the base frame. An upper micro switch and a lower micro switch are disposed on the detection support plate near the end of the lifting bracket, spaced vertically. When the lifting bracket rises to the highest position, the upper micro switch touches the upper detection ramp. When the lifting bracket falls to the lowest position, the lower micro switch touches the lower detection ramp.

[0013] By adopting the above technical solution and through the setting of the detection components, when the lifting frame rises to the highest position, the upper micro switch touches the upper detection ramp, and the upper micro switch detects the signal, thus determining that the lifting frame (i.e., the comb mechanism) has risen to the highest position; when the lifting frame descends to the lowest position, the lower micro switch touches the lower detection ramp, and the lower micro switch detects the signal, thus determining that the lifting frame (i.e., the comb mechanism) has descended to the lowest position. This can cooperate with the limit components to prevent excessive lifting and avoid excessive rotation of the spiral lifting wheel, collision or detachment of the lifting support wheel from the arc-shaped ramp groove, and subsequent jamming.

[0014] Optionally, the bottom of the spiral lifting wheel is provided with a base bracket, and a base support wheel that is rotatably mounted on the base bracket and supported on the bottom of the spiral lifting wheel.

[0015] By adopting the above technical solution, the bottom support rollers can provide support at the bottom of the spiral lifting wheel, thereby enhancing its strength, extending its service life, and improving its stability.

[0016] Optionally, the base frame is provided with a guide shaft, and the lifting frame is provided with a guide sleeve that cooperates with the guide shaft.

[0017] By adopting the above technical solution, the cooperation between the guide shaft and the guide sleeve helps to improve the lifting stability of the lifting frame.

[0018] Optionally, the first comb tooth power assembly includes a first comb tooth motor unit mounted on the lifting frame, the first comb tooth motor unit driving the lead screw to rotate, and the front and rear threads of the lead screw have opposite directions;

[0019] A front lead screw is provided in conjunction with the front lead screw. Front connecting rod assemblies are symmetrically arranged on both sides of the front lead screw. The front connecting rod assembly includes a front connecting rod A that is hinged to the front lead screw. The front connecting rod A is hinged to the front connecting rod B. One end of the front connecting rod B is hinged to the lifting frame, and the hinge point between the front connecting rod B and the lifting frame is located at the front end of the front lead screw. The other end of the front connecting rod B is hinged to the front connecting rod C. The front connecting rod C is hinged to the first left comb tooth frame and the first right comb tooth frame.

[0020] A rear lead screw is provided in conjunction with the rear lead screw. A rear connecting rod assembly is symmetrically provided at both ends of the rear lead screw assembly. The rear connecting rod assembly includes a rear connecting rod A that is hinged to the rear lead screw assembly. The rear connecting rod A is hinged to the rear connecting rod B. One end of the rear connecting rod B is hinged to the lifting frame, and the hinge point between the rear connecting rod B and the lifting frame is located at the rear end of the rear lead screw assembly. The other end of the rear connecting rod B is hinged to the rear connecting rod C. The rear connecting rod C is hinged to the first left comb tooth frame and the first right comb tooth frame.

[0021] By adopting the above technical solution, the first comb tooth motor unit drives the lead screw to rotate, which in turn drives the lead sleeve that cooperates with the lead screw to move. Through the linkage motion, the extension and retraction of the first left comb tooth frame and the first right comb tooth frame are realized. The extension and retraction of the first left comb tooth frame and the first right comb tooth frame have good synchronization, are easy to control, and have strong stability.

[0022] Optionally, the lifting frame has two sections, one in front and one in back, with the two lifting frames sharing a common spiral lifting wheel at their adjacent ends; the comb mechanism further includes a second comb mechanism, with the first comb mechanism mounted on one lifting frame and the second comb mechanism mounted on the other lifting frame; the second comb mechanism includes a second left comb frame and a second right comb frame, which are slidably mounted on the lifting frame along the left-right width direction of the base frame, and are driven to slide by a second comb power assembly mounted on the lifting frame.

[0023] Optionally, the second comb gear power assembly includes a comb gear rotatably mounted on the lifting frame. The comb gear is driven to rotate by a second comb motor mounted on the lifting frame. A left comb rack is mounted on the second left comb frame, and a right comb rack is mounted on the second right comb frame. The left and right comb racks mesh with the front and rear sides of the comb gear, respectively.

[0024] By adopting the above technical solution, under the drive of the second comb motor unit, the comb gear meshes with the left and right comb racks, driving the second left and second right comb frames to slide, thereby realizing the extension and retraction of the comb teeth.

[0025] Optionally, the walking device includes a support mechanism, a drive mechanism, and a steering drive mechanism;

[0026] The drive mechanism is located at one end of the base frame and includes drive wheels that are symmetrically rotated on both sides of the base frame. The drive wheels are driven to rotate by the drive power unit A mounted on the base frame through sprocket and chain transmission.

[0027] The steering drive mechanism is located on both sides of the other end of the chassis. The steering drive mechanism includes a rotating seat fixedly connected to the chassis. A drive wheel seat is rotatably mounted on the bottom of the rotating seat. A fixed rotating gear concentric with the rotation center of the drive wheel seat is fixedly mounted on the bottom of the rotating seat. A steering power unit is mounted on the drive wheel seat. The steering power unit drives a moving rotating gear meshing with the fixed rotating gear to rotate. The steering drive wheel is located at the bottom of the drive wheel seat and is driven to rotate by the drive power unit B mounted on the drive wheel seat.

[0028] The support mechanism is located between the drive mechanism and the steering drive mechanism, and includes walking support wheels that are symmetrically rotated on both sides of the base frame.

[0029] By adopting the above technical solution, the drive mechanism, driven by drive power unit A, rotates the drive wheel, supporting and driving the chassis to move. The steering drive mechanism, driven by drive power unit B, rotates the steering drive wheel, supporting and driving the chassis to move. Driven by the rotational power unit, the drive wheel seat rotates through gear meshing, thereby changing the direction of the steering drive wheel and achieving steering of the chassis's movement. The support mechanism's walking support wheels only serve a supporting function.

[0030] Optionally, the drive mechanism further includes a tensioning assembly, which includes a tensioning sprocket rotatably mounted on an adjusting plate. The tensioning sprocket is configured to cooperate with a chain. One end of the adjusting plate is hinged to the base frame, and the other end of the adjusting plate is hinged to a threaded shaft. A fixing plate is provided on the base frame, and a U-shaped groove is provided on the fixing plate. The threaded shaft is located in the U-shaped groove, and nuts are tightened on the threaded shafts located on both sides of the fixing plate.

[0031] By adopting the above technical solution, the swing position of the adjusting plate can be adjusted by adjusting the position of the two nuts on the threaded shaft, thereby adjusting the position of the tension sprocket, tightening or loosening the chain, realizing the adjustment of chain tension, improving the driving stability of the drive mechanism, and ensuring the stable movement of the chassis.

[0032] Optionally, guide wheels are rotatably connected to all four corners of the base frame.

[0033] By adopting the above technical solution, the guide wheel can act as a guide by contacting the side wall of the parking space when the underframe enters the parking space.

[0034] In summary, this application includes at least the following beneficial effects:

[0035] 1. This application utilizes a chassis to support and drive the integrated telescopic comb transporter for transportation. The comb mechanism can carry the vehicle, and the lifting support wheels can roll along the inclined surface of the arc-shaped ramp, thereby driving the lifting support wheels and the lifting frame to rise and fall, which in turn drives the comb frame to rise and fall.

[0036] 2. This application, through the setting of a limit component, ensures that when the spiral lifting wheel rotates and drives the lifting frame to its highest position, the limit cylinder moves the limit rod, causing the limit rod to insert into the limit groove, stopping the spiral lifting wheel from rotating and completing the lifting frame's upward operation. This limits the upward movement of the lifting mechanism and the comb mechanism, improving the safety, stability, and accuracy of the upward movement. Through the setting of the detection component, when the lifting frame rises to its highest position, the upper microswitch contacts the upper detection ramp, detecting a signal and thus determining that the lifting frame (i.e., the comb mechanism) has reached its highest position; when the lifting frame descends to its lowest position, the lower microswitch contacts the lower detection ramp, detecting a signal and thus determining that the lifting frame (i.e., the comb mechanism) has descended to its lowest position. This, in conjunction with the limit component, prevents excessive lifting and avoids excessive rotation of the spiral lifting wheel, or even collisions or detachment of the lifting support wheel from the arc-shaped ramp groove, causing jamming.

[0037] 3. This application uses the first comb tooth motor unit to drive the lead screw to rotate, which in turn drives the lead sleeve that cooperates with the lead screw to move. Through the linkage motion, the extension and retraction of the first left comb tooth frame and the first right comb tooth frame are realized. The extension and retraction of the first left comb tooth frame and the first right comb tooth frame have good synchronization, are easy to control, and have strong stability.

[0038] 4. The bottom of the spiral lifting wheel of this application is provided with a base bracket, and a base support wheel is rotatably mounted on the base bracket, supporting the bottom of the spiral lifting wheel. The base support wheel provides support to the bottom of the spiral lifting wheel, providing a certain support force, which helps to enhance the strength of the spiral lifting wheel, extend its service life, and improve its stability.

[0039] 5. This application, through the configuration of the drive mechanism, enables the drive wheel to rotate under the drive power unit A, thereby supporting and driving the chassis to move. The steering drive mechanism, driven by the drive power unit B, enables the steering drive wheel to rotate, supporting and driving the chassis to move. Driven by the rotation power unit, the drive wheel seat rotates through gear meshing, thus changing the direction of the steering drive wheel and achieving steering of the chassis's movement. The support mechanism's walking support wheel only serves a supporting function. Attached Figure Description

[0051] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0052] The following is in conjunction with the appendix Figures 1 to 9 This application will be described in further detail.

[0053] This application discloses a telescopic comb transporter.

[0054] Reference Figures 1 to 9 A telescopic comb transporter includes a walking chassis and a comb lifting device.

[0055] The chassis includes a base frame 1 and a traveling device mounted on the base frame 1. The traveling device is used to support and drive the base frame 1 to travel.

[0056] Guide wheels 2 are rotatably connected to the four corners of the base frame 1. The guide wheels 2 can act as guides when the base frame 1 enters the parking space and comes into contact with the side wall of the parking space.

[0057] The walking device includes a support mechanism, a drive mechanism, and a steering drive mechanism.

[0058] The support mechanism is located in the middle of the base frame 1 and includes symmetrically rotating walking support wheels 3 on both sides of the base frame 1. The walking support wheels 3 only serve a supporting function.

[0059] The drive mechanism is located at one end of the base frame 1 and includes drive wheels 4 symmetrically arranged on both sides of the base frame 1. The drive wheels 4 are driven to rotate by a drive power unit A mounted on the base frame 1 through a sprocket and chain transmission. The drive power unit A can be a motor assembly. The drive mechanism, driven by the drive power unit A, rotates the drive wheels 4, thus supporting and driving the base frame 1 to move.

[0060] The drive mechanism also includes a tensioning assembly, which includes a tensioning sprocket 6 rotatably mounted on an adjusting plate 5. The tensioning sprocket 6 is configured to cooperate with the chain. One end of the adjusting plate 5 is hinged to the base frame 1, and the other end of the adjusting plate 5 is hinged to a threaded shaft 7. A fixed plate 8 is mounted on the base frame 1, and a U-shaped groove 9 is formed on the fixed plate 8. The threaded shaft 7 is located within the U-shaped groove 9, and nuts 10 are tightened on the threaded shaft 7 on both sides of the fixed plate 8. By adjusting the positions of the two nuts 10 on the threaded shaft 7, the swing position of the adjusting plate 5 can be adjusted, thereby adjusting the position of the tensioning sprocket 6, tightening or loosening the chain, realizing chain tension adjustment, improving the driving stability of the drive mechanism, and ensuring stable movement of the chassis.

[0061] The steering drive mechanism is located on both sides of the other end of the base frame 1. The steering drive mechanism includes a rotating seat 11 fixedly connected to the base frame 1. A drive wheel seat 12 is rotatably mounted on the bottom of the rotating seat 11. A fixed rotating gear 13, concentric with the rotation center of the drive wheel seat 12, is fixedly mounted on the bottom of the rotating seat 11. A steering power unit 14, which can be a motor, is mounted on the drive wheel seat 12. The steering power unit 14 drives a moving rotating gear 15 meshing with the fixed rotating gear 13 to rotate. A steering drive wheel 16 is located at the bottom of the drive wheel seat 12 and is driven to rotate by a drive power unit B17, which can also be a motor. The steering drive mechanism, driven by the drive power unit B17, rotates the steering drive wheel 16, supporting and driving the base frame 1 to move. Driven by the rotating power unit, the drive wheel seat 12 rotates through gear meshing, thereby changing the direction of the steering drive wheel 16 and achieving steering of the base frame 1.

[0062] The walking chassis supports and drives the entire telescopic comb transporter to move, thus enabling transportation.

[0063] The lifting comb device includes a lifting mechanism and a comb mechanism. The comb mechanism can support the vehicle. The lifting mechanism is mounted on the base frame 1 and is used to drive the comb mechanism to lift and lower, thereby driving the vehicle to lift and lower.

[0064] The lifting mechanism includes a lifting frame 18, a limit component, and a detection component.

[0065] Two lifting brackets 19 are spaced apart at both ends of the lifting frame 18, and lifting support wheels 20 are rotatably mounted on the two lifting brackets 19. The lifting mechanism also includes spiral lifting wheels 21 located at both ends of the lifting frame 18. Two arc-shaped inclined grooves 22 are opened on the outer side of the spiral lifting wheel 21 in a circumferential direction. The spiral lifting wheel 21 is rotatably supported on the base frame 1 and is driven to rotate by a lifting power component. The lifting power component can be a motor unit, which drives the spiral lifting wheel 21 to rotate through a sprocket and chain transmission. The lifting support wheels 20 are located in the arc-shaped inclined grooves 22.

[0066] A base bracket 23 is provided at the bottom of the spiral lifting wheel 21, and a base support wheel 24 is rotatably mounted on the base bracket 23, supporting the bottom of the spiral lifting wheel 21. The base support wheel 24 provides support at the bottom of the spiral lifting wheel 21, providing a certain support force, which helps to enhance the strength of the spiral lifting wheel 21, extend its service life, and improve its stability.

[0067] The lifting frame 18 has two parts, front and back, and the two lifting frames 18 share a common spiral lifting wheel 21 at their adjacent ends.

[0068] A guide shaft 25 is provided on the base frame 1, and a guide sleeve 26 is provided on the lifting frame 18 to guide and cooperate with the guide shaft 25. The cooperation between the guide shaft 25 and the guide sleeve 26 helps to improve the lifting stability of the lifting frame 18.

[0069] The limiting assembly includes a limiting cylinder 27 hinged to the base frame 1, a limiting rod 28 hinged to the limiting rod bracket 29, and a limiting cylinder 27 hinged to one end of the limiting rod 28. The limiting cylinder 27 drives the limiting rod 28 to move, that is, drives the limiting rod 28 to swing. The bottom of the spiral lifting wheel 21 has a limiting groove 30. When the spiral lifting wheel 21 rotates and drives the lifting frame 18 to rise to the highest position, the other end of the limiting rod 28 is inserted into the limiting groove 30 to limit the spiral lifting wheel 21 to continue to rotate.

[0070] The detection assembly includes an upper detection ramp 31 and a lower detection ramp 32 located at the top and bottom of the end of the lifting bracket 19, respectively. A detection support plate 33 is mounted on the base frame 1. An upper micro switch 34 and a lower micro switch 35, spaced apart vertically, are mounted on the detection support plate 33 near the end of the lifting bracket 19. When the lifting bracket 18 rises to its highest position, the upper micro switch 34 contacts the upper detection ramp 31. When the lifting bracket 18 descends to its lowest position, the lower micro switch 35 contacts the lower detection ramp 32. Through this detection assembly, when the lifting bracket 18 rises to its highest position, the upper micro switch 34 contacts the upper detection ramp 31, detecting a signal, thus indicating that the lifting bracket 18 (i.e., the comb mechanism) has reached its highest position. When the lifting bracket 18 descends to its lowest position, the lower micro switch 35 contacts the lower detection ramp 32, detecting a signal, thus indicating that the lifting bracket 18 (i.e., the comb mechanism) has descended to its lowest position. It can work with the limit component to prevent excessive lifting and avoid excessive rotation of the spiral lifting wheel 21, and prevent the lifting support wheel 20 from colliding with or detaching from the arc-shaped ramp 22, causing jamming.

[0071] The lifting support wheel 20 can roll along the inclined surface of the arc-shaped ramp 22, thereby driving the lifting support wheel 20 and the lifting frame 18 to rise and fall, and in turn driving the comb frame to rise and fall. When the spiral lifting wheel 21 rotates and drives the lifting frame 18 to rise to the highest position, the limit cylinder 27 drives the limit rod 28 to move, so that the limit rod 28 inserts into the limit groove 30, causing the spiral lifting wheel 21 to stop rotating, and the lifting frame 18 to complete the rising operation. This ensures that the rising of the lifting mechanism and the comb mechanism is limited, improving the safety, stability and accuracy of the rising.

[0072] The comb mechanism includes a first comb mechanism and a second comb mechanism. The first comb mechanism is mounted on a lifting frame 18 at one end of the base frame 1, and the second comb mechanism is mounted on a lifting frame 18 at the other end of the base frame 1.

[0073] The first comb tooth mechanism includes a first left comb tooth frame 36 and a first right comb tooth frame 37. The first left comb tooth frame 36 and the first right comb tooth frame 37 are slidably mounted on the lifting frame 18 along the left and right width direction of the base frame 1. The first left comb tooth frame 36 and the first right comb tooth frame 37 are slidably mounted by a first comb tooth power assembly mounted on the lifting frame 18. Both the first left comb tooth frame 36 and the first right comb tooth frame 37 are provided with multiple comb teeth.

[0074] The first comb tooth power assembly includes a first comb tooth motor unit 38 mounted on the lifting frame 18. The first comb tooth motor unit 38 drives the lead screw 39 to rotate, and the front and rear threads of the lead screw 39 are in opposite directions.

[0075] A front lead screw 40 is provided in conjunction with the front lead screw 39. Front connecting rod assemblies are symmetrically arranged on both sides of the front lead screw 40. The front connecting rod assembly includes a front connecting rod A41 that is hinged to the front lead screw 40. The front connecting rod A41 is hinged to the front connecting rod B42. One end of the front connecting rod B42 is hinged to the lifting frame 18, and the hinge point between the front connecting rod B42 and the lifting frame 18 is located at the front end of the front lead screw 40. The other end of the front connecting rod B42 is hinged to the front connecting rod C43. The front connecting rod C43 is hinged to the first left comb tooth frame 36 and the first right comb tooth frame 37.

[0076] A rear threaded sleeve 44 is provided in conjunction with the rear threaded screw 39. Rear connecting rod assemblies are symmetrically arranged at both ends of the rear threaded sleeve 44. The rear connecting rod assembly includes a rear connecting rod A45 that is hinged to the rear threaded sleeve 44. The rear connecting rod A45 is hinged to the rear connecting rod B46. One end of the rear connecting rod B46 is hinged to the lifting frame 18, and the hinge point between the rear connecting rod B46 and the lifting frame 18 is located at the rear end of the rear threaded sleeve 44. The other end of the rear connecting rod B46 is hinged to the rear connecting rod C47. The rear connecting rod C47 is hinged to the first left comb tooth frame 36 and the first right comb tooth frame 37.

[0077] The first comb tooth motor group 38 drives the lead screw 39 to rotate, which in turn drives the lead sleeve that cooperates with the lead screw 39 to move. The linkage movement realizes the extension and retraction of the first left comb tooth frame 36 and the first right comb tooth frame 37. The extension and retraction of the first left comb tooth frame 36 and the first right comb tooth frame 37 have good synchronization, are easy to control, and have strong stability.

[0078] The second comb mechanism includes a second left comb frame 48 and a second right comb frame 49. The second left comb frame 48 and the second right comb frame 49 are slidably mounted on the lifting frame 18 along the left and right width direction of the base frame 1. The second left comb frame 48 and the second right comb frame 49 are slidably mounted by a second comb power assembly mounted on the lifting frame 18. Each of the second left comb frame 48 and the second right comb frame 49 is provided with two comb teeth.

[0079] The second comb gear power assembly includes a comb gear rotatably mounted on the lifting frame 18. The comb gear is located inside the gearbox 50, and a sprocket is coaxially fixed at its bottom. The comb gear is driven to rotate by a second comb gear motor unit mounted on the lifting frame 18 via a sprocket and chain drive. A left comb gear rack 51 is mounted on the second left comb gear frame 48, and a right comb gear rack 52 is mounted on the second right comb gear frame 49. The left and right comb gear racks 51 and 52 mesh with the front and rear sides of the comb gear, respectively. Driven by the second comb gear motor unit, the comb gear meshes with the left and right comb gear racks 51 and 52, causing the second left and right comb gear frames 48 and 49 to slide, thus achieving the extension and retraction of the comb teeth.

[0080] Working principle:

[0081] When the chassis 1 needs to be moved to transport the vehicle, the chassis 1 moves under the drive of the traveling device. The guide wheels 2 abut against the side wall of the parking space to guide the movement and improve the accuracy of the chassis 1.

[0082] After the frame moves to the bottom of the vehicle, the first and second comb-tooth mechanisms operate. Once the comb teeth have fully extended, the lifting mechanism operates, and the spiral lifting wheel 21 rotates. During its rotation, the spiral lifting wheel 21 pushes the lifting support wheel 20 to rotate and roll along the inclined surface of the arc-shaped ramp 22. When the lifting support wheel 20 gradually rolls from the lowest point of the arc-shaped ramp 22 to the highest point, the lifting mechanism drives the comb-tooth mechanism to rise. Conversely, when the lifting support wheel 20 gradually rolls from the highest point of the arc-shaped ramp 22 to the lowest point, the lifting mechanism drives the comb-tooth mechanism to descend. Once the comb-tooth mechanism has risen, the vehicle rises and leaves the ground, ready for transport.
