Rotatable carrier plate structure

Abstract

This invention relates to the field of garages, specifically to a rotatable vehicle platform structure, comprising a traveling device including a drive rod, a first roller, a second roller, and a turning wheel. The drive rod is rotatably mounted on the vehicle platform, with both the first and second rollers mounted on the drive rod, and the turning wheel engaging with the drive rod. A straight-line guide rail is located on one side of the vehicle platform, with both the first roller and the turning wheel embedded in it. A turning guide rail is connected to the end of the straight-line guide rail and offset from it, with a turning support plate on the side of the turning guide rail closest to the straight-line guide rail. The drive rod drives the first and second rollers to rotate. When the first roller moves off the straight-line guide rail, the turning wheel moves onto the turning support plate, creating a speed difference between the turning wheel and the second roller. The second roller pushes the turning wheel to turn on the turning support plate, thus enabling the vehicle platform to turn. This transmission structure is simpler overall than a differential, effectively saving costs.

Description

Technical Field

[0001] This invention relates to the field of garages, and in particular to a rotatable vehicle platform structure. Background Technology

[0002] Currently, downward-spinning, non-avoidance automated parking systems have a cost-effective advantage compared to two-story lift-and-slide automated parking systems because they can truly achieve a 1:2 parking ratio. At the same time, with the introduction of new regulations, most simple lift-type automated parking systems can no longer be calculated based on a 1:2 parking ratio, which will greatly increase the demand for downward-spinning, non-avoidance automated parking systems.

[0003] Most down-rotating, non-avoidance automated parking systems in the industry use a differential to connect the drive wheels via a transmission shaft and employ a turning guide rail for guidance. When the vehicle platform moves to the corner of the track, the differential drives the wheels at both ends to rotate at different speeds, thus achieving turning in motion. This type of drive system has a relatively complex structure and high cost. Summary of the Invention

[0004] To solve at least one of the above-mentioned technical problems, the present invention provides a rotatable vehicle platform structure, and the technical solution adopted is as follows.

[0005] A rotatable vehicle platform structure includes a vehicle platform and further includes...

[0006] A walking device includes a transmission rod, a first roller, a second roller, and a turning wheel. The transmission rod is rotatably mounted on the vehicle platform. The first roller and the second roller are both mounted on the transmission rod. The turning wheel is engaged with the transmission rod and can rotate on the transmission rod.

[0007] A straight guide rail is provided on one side of the vehicle platform, and the first roller and the turning wheel are both located in the straight guide rail;

[0008] A turning guide rail is connected to the end of the straight guide rail and is offset from the straight guide rail. A turning support plate is provided on the side of the turning guide rail near the straight guide rail. The turning support plate is used to support the turning wheel to move independently.

[0009] The rotatable vehicle platform structure of this invention has at least the following beneficial effects: During use, the transmission rod drives the first roller and the second roller to rotate and move. The first roller moves in the straight guide rail, and the second roller moves on the ground. When the first roller moves out of the straight guide rail, the turning wheel moves onto the turning support plate, while the first roller is suspended on the outside of the turning support plate. At this time, the rollers supporting the vehicle platform are the second roller and the turning wheel. Since the turning wheel is rotatably connected to the transmission rod, the force that drives the second roller forward is not transmitted to the turning wheel. Therefore, a speed difference is formed between the turning wheel and the second roller. The walking speed of the second roller is greater than that of the turning wheel. As the second roller continues to move, it pushes the turning wheel to turn on the turning support plate, thereby realizing the turning of the entire vehicle platform. This transmission structure can achieve the effect of differential turning without the use of a differential, and the turning effect is also very good. The overall structure is simpler than that of a differential, effectively saving manufacturing costs.

[0010] According to other embodiments of the present invention, in a rotatable vehicle platform structure, the turning wheel is disposed on the side of the first roller and rotatably connected to the transmission rod.

[0029] Currently, downward-spinning, non-avoidance automated parking systems have a cost-effective advantage compared to two-story lift-and-slide automated parking systems because they can truly achieve a 1:2 parking ratio. At the same time, with the introduction of new regulations, most simple lift-type automated parking systems can no longer be calculated based on a 1:2 parking ratio, which will greatly increase the demand for downward-spinning, non-avoidance automated parking systems.

[0030] Most down-rotating, non-avoidance automated parking systems in the industry use a differential to connect the drive wheels via a transmission shaft and employ a turning guide rail for guidance. When the vehicle platform moves to the corner of the track, the differential drives the wheels at both ends to rotate at different speeds, thus achieving turning in motion. This type of drive system has a relatively complex structure and high cost.

[0031] To address the aforementioned technical problems, this invention provides a rotatable vehicle platform structure.

[0032] See Figures 1 to 5The rotatable vehicle platform structure includes a vehicle platform, a traveling device 200, a straight guide rail 300, and a turning guide rail 400. The traveling device 200 includes a transmission rod 210, a first roller 211, a second roller 212, and a turning wheel 213. The transmission rod 210 is rotatably mounted on the vehicle platform 001. The first roller 211 and the second roller 212 are both mounted on the transmission rod 210. The turning wheel 213 is engaged with the transmission rod 210 and can rotate on the transmission rod 210. The straight guide rail 300 is located on one side of the vehicle platform 001. The first roller 211 and the turning wheel 213 are both located in the straight guide rail 300. The turning guide rail 400 is connected to the end of the straight guide rail 300 and is offset from the straight guide rail 300. A turning support plate 301 is provided on the side of the turning guide rail 400 near the straight guide rail 300. The turning support plate 301 is used to support the turning wheel 213 to move independently.

[0033] During operation, the transmission rod 210 drives the first roller 211 and the second roller 212 to move. The first roller 211 moves within the straight guide rail 300, while the second roller 212 moves on the ground. When the first roller 211 moves out of the straight guide rail 300, the turning wheel 213 moves onto the turning support plate 301, while the first roller 211 hangs suspended outside the turning support plate 301 and spins freely. At this time, the rollers supporting the vehicle platform 001 are the second roller 212 and the turning wheel 213. Since the turning wheel 213 is rotatably connected to the transmission rod 210, the transmission rod 210... The force that drives the second roller 212 forward will not be transmitted to the turning wheel 213. Therefore, a speed difference will be formed between the turning wheel 213 and the second roller 212. The walking speed of the second roller 212 is greater than that of the turning wheel 213. As the second roller 212 continues to move, it will push the turning wheel 213 to turn on the turning support plate 301, thereby realizing the turning of the vehicle platform 001. This transmission structure can achieve the effect of differential turning without the use of a differential, and the turning effect is also very good. The overall structure is simpler than that of a differential, effectively saving manufacturing costs.

[0034] The vehicle platform 001 includes a front crossbeam 011, a rear crossbeam 012, a left longitudinal beam 013, and a right longitudinal beam 014. The left longitudinal beam 013 and the right longitudinal beam 014 are arranged opposite each other at intervals. The front crossbeam 011 and the rear crossbeam 012 are respectively fixed to the front and rear ends of the left longitudinal beam 013 and the right longitudinal beam 014.

[0035] In some embodiments, a drive device 500 is installed on the vehicle platform 001, a drive wheel 501 is installed at the power output end of the drive device 500, a driven wheel 502 is installed on the transmission rod 210, and the drive wheel 501 and the driven wheel 502 are connected through a transmission component.

[0036] Specifically, a mounting base 600 is provided on the rear crossbeam 012 of the vehicle platform 001. The drive device 500 is fixed on the mounting base 600. Both the drive wheel 501 and the driven wheel 502 are sprockets. The drive wheel 501 is fixed on the power output shaft of the drive device 500, and the driven wheel 502 is fixed on the transmission rod 210. The drive wheel 501 and the driven wheel 502 are connected by a transmission chain. During operation, the drive device 500 drives the drive wheel 501 to rotate. The drive wheel 501 drives the driven wheel 502 to rotate through the transmission chain. The driven wheel 502 drives the transmission rod 210 to rotate. The transmission rod 210 drives the first roller 211 and the second roller 212 to rotate.

[0037] In some embodiments, a first connecting plate 015 and a second connecting plate 016 are respectively provided on the two longitudinal beams of the vehicle platform 001. The first connecting plate 015 and the second connecting plate 016 are arranged opposite to each other, and the transmission rod 210 is rotatably installed between the first connecting plate 015 and the second connecting plate 016.

[0038] Specifically, a first connecting plate 015 is installed at the rear end of the left longitudinal beam 013 of the vehicle platform 001, and a second connecting plate 016 is installed at the rear end of the right longitudinal beam 014 of the vehicle platform 001. The first connecting plate 015 and the second connecting plate 016 extend rearward along the length of the longitudinal beam. The first connecting plate 015 and the second connecting plate 016 are arranged opposite to each other. The two ends of the transmission rod 210 are rotatably connected to the first connecting plate 015 and the second connecting plate 016 through bearings. The second roller 212 is located inside the second connecting plate 016, and the first roller 211 and the turning wheel 213 are located outside the first connecting plate 015.

[0039] To improve the forward stability of the vehicle platform 001, in some embodiments, the side of the vehicle platform 001 away from the walking device 200 is provided with casters 017.

[0040] Specifically, two casters 017 are installed at the bottom of the front crossbeam 011 of the vehicle platform 001, and the two casters 017 are arranged at intervals along the length of the front crossbeam 011.

[0041] To improve the stability of the vehicle platform 001 as it travels in the straight guide rail 300, in some embodiments, the rotatable vehicle platform structure further includes a first guide device 700. The first guide device 700 includes a support rod 701 and a first guide wheel 702. One end of the support rod 701 is fixed to the vehicle platform 001, and the other end of the support rod 701 is equipped with the first guide wheel 702, which is located inside the straight guide rail 300.

[0042] Specifically, the support rod 701 is a square tube structure. One end of the support rod 701 is fixed to the side of the left longitudinal beam 013 by a mounting plate. The first guide wheel 702 is installed horizontally below the support rod 701 by a rotating shaft. The first guide wheel 702 is located in the straight guide rail 300. When the vehicle platform 001 moves forward in the straight guide rail 300, the first guide wheel 702 will roll synchronously in the straight guide rail 300 to improve the stability of the vehicle platform 001 moving in the straight guide rail 300.

[0043] In some embodiments, the turning wheel 213 is disposed on the side of the first roller 211 and is rotatably connected to the transmission rod 210.

[0044] Specifically, the turning wheel 213 is rotatably mounted on the outside of the first roller 211, and both the turning wheel 213 and the first roller 211 are located inside the straight guide rail 300. This way, installing the turning wheel 213 and the first roller 211 together can effectively save space.

[0045] The straight guide rail 300 is a channel steel structure. The straight guide rail 300 extends along the length of the longitudinal beam. Angle steel 302 is welded to both sides of the straight guide rail 300. The angle steel 302 is used to fix it to the ground. The straight guide rail 300 is located below the first roller 211. The first roller 211 and the turning wheel 213 are directly embedded in the straight guide rail 300 and can move in the straight guide rail 300.

[0046] A turning guide rail 400 is located at the end of the straight guide rail 300. The turning guide rail 400 includes a base plate 401 and two arc-shaped curved plates 402 that are vertically fixed on the base plate 401. The two arc-shaped curved plates 402 are arranged at intervals. A turning support plate 301 with the same bending direction as the arc-shaped curved plates 402 is provided on the side of the turning guide rail 400 near the straight guide rail 300. The turning support plate 301 and the base plate 401 are integral structures. The turning support plate 301 is connected to the inside of the straight guide rail 300.

[0047] To ensure the stability of the vehicle platform 001 in the turning guide rail 400, in some embodiments, a second guide device 800 is installed on the vehicle platform 001. The second guide device 800 includes a support frame 810 and a second guide wheel 820. The support frame 810 is installed on the first connecting plate 015, and the second guide wheel 820 is installed on the support frame 810. The second guide wheel 820 is located outside the straight guide rail 300 and is used to travel in the turning guide rail 400.

[0048] Specifically, the support frame 810 includes two square tubes and a rectangular plate. One end of each of the two square tubes is fixed to the first connecting plate 015 with screws. The rectangular plate is horizontally fixed to the other end of the two square tubes. Two second guide wheels 820 are horizontally mounted on the underside of the rectangular plate via a rotating shaft. The two second guide wheels 820 are arranged at intervals along the length of the rectangular plate. Both second guide wheels 820 are located on the outside of the straight guide rail 300. When the vehicle platform 001 moves to the end of the straight guide rail 300, the two second guide wheels 820 will move into the turning guide rail 400. As the second roller 212 continues to move, it pushes the turning wheel 213 to turn on the turning support plate 301. The synchronous turning motion of the two second guide wheels 820 in the turning guide rail 400 can ensure the stability of the vehicle platform 001 during the turning process.

[0049] In some embodiments, the support frame 810 is fixed to the vehicle platform 001 across the turning wheel 213 and the first roller 211.

[0050] Specifically, the two square tubes of the support frame 810 are located on both sides of the first roller 211 and the turning wheel 213, respectively, and the rectangular plate is located on the outside of the turning wheel 213. The rectangular plate and the two square tubes form a support frame 810 that surrounds the first roller 211 and the turning wheel 213. In this way, the second guide device 800, the first roller 211, and the turning wheel 213 are installed in the same position, which effectively reduces the space occupancy rate.

[0051] In some embodiments, a positioning block is installed on the turning guide rail 400, and a positioning switch is provided on the support frame 810. When the vehicle platform 001 is in place, the positioning switch is activated to stop the operation of the positioning block.

[0052] Specifically, the positioning block is fixed to the turning guide rail 400 by the first bending plate, and the positioning switch is fixed to the rectangular plate of the support frame 810 by the second bending plate. When the vehicle plate 001 turns in the turning guide rail 400 until the positioning switch contacts the positioning block, it indicates that the vehicle plate 001 has turned into position, and the vehicle plate 001 will not move anymore.

[0053] Of course, this application is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
