Description

Technical Field

[0001] This utility model relates to the field of parking equipment technology, and in particular to a mechanical parking device and its vehicle blocking system. Background Technology

[0002] Currently, unmanned or semi-unmanned mechanical parking systems (such as vertical lifting parking systems, horizontal moving parking systems, aisle stacking parking systems, and robot-assisted parking systems) typically include entrance / exit doors, a transfer area, a work area door, a work area, and a transporter / robot. The entrance / exit door is located at the entrance / exit of the transfer area, which contains parking platforms. The work area door is located in front of the parking platforms. The transporter / robot operates between the transfer area and the work area, used to move vehicles from the transfer area to parking spaces in the work area, or vice versa. The work area is the main area for automated equipment operation and vehicle storage.

[0003] When parking a vehicle, the work area door closes, the entrance / exit door opens, the driver drives the vehicle onto the parking platform, stops it, and leaves the transition area, then issues a parking command. Next, the entrance / exit door closes, the work area door opens, and the transporter / robot enters the transition area from the work area, moving the vehicle to its designated parking space.

[0004] However, when a vehicle enters the parking space at too high a speed, or if the driver makes a mistake, the vehicle may veer forward off the parking platform and crash into the work area door, causing damage to the vehicle and equipment. In severe cases, the vehicle may even crash into the work area, endangering the driver's safety. Utility Model Content

[0039] Figure 1 This is a schematic side view of the vehicle stopper of a mechanical parking device according to an embodiment of the present invention in the vehicle-stopping state, as shown. Figure 1 As shown, and refer to Figures 2 to 6 This utility model provides a vehicle blocking system for a mechanical parking device 10, including a vehicle blocker 100, a drive device 200, and a linkage device 300.

[0040] A vehicle stopper 100 is disposed within the transition area 520 of the parking equipment 10, and is located in front of the parking platform 550 of the transition area 520. The vehicle stopper 100 has a vehicle-stopping state and a yielding state. A drive unit 200 is disposed within the transition area 520. A linkage device 300 is drivingly connected to the drive unit 200, the vehicle stopper 100, and the entrance / exit gate 510 of the parking equipment 10, so that when the drive unit 200 performs a first action, the entrance / exit gate 510 is opened by the linkage device 300, and the vehicle stopper 100 is switched to the vehicle-stopping state by the linkage device 300; and when the drive unit 200 performs a second action, the entrance / exit gate 510 is closed by the linkage device 300, and the vehicle stopper 100 is switched to the yielding state by the linkage device 300.

[0041] The mechanical parking equipment 10 can be a vertical lifting parking equipment, a horizontal moving parking equipment, a lane stacking parking equipment, or a handling robot parking equipment, etc. The mechanical parking equipment 10 can be equipped with entrance / exit doors 510, a transition area 520, a work area door 530, a work area 540, and a transporter / transport robot, etc. The transition area 520 and the work area 540 are typically relatively enclosed areas. The transition area 520 is typically the area where, during vehicle storage and retrieval, the driver's driving state is switched to the parking equipment 10's control state, or vice versa. The work area 540 is typically the area where the parking equipment 10 operates and stores vehicles; drivers are not allowed to enter this area. The transporter / transport robot operates in the transition area 520 and the work area 540 to transport vehicles parked in the transition area 520 to the work area 540 and place them in designated parking spaces.

[0042] When parking, drivers must slowly drive the vehicle onto the parking platform 550 and park it in the designated position. If the vehicle is traveling too fast or the driver makes a mistake, the vehicle may easily veer forward off the parking platform 550 and crash into the work area door 530, causing damage to the vehicle and equipment. In severe cases, the vehicle may even crash into the work area 540, endangering the personal safety of the driver.

[0043] In this embodiment, a vehicle stopper 100 is installed on the front side of the parking platform 550, that is, the vehicle stopper 100 is located between the parking platform 550 and the work area door 530, to stop vehicles and prevent them from rushing forward out of the parking platform 550 and colliding with the work area door 530. The vehicle stopper 100 can use various forms to stop vehicles. For example, the vehicle stopper 100 can use a liftable stop bar, which can be slidably installed on the vertical guide rail or the side wall where the work area door 530 is located. When the stop bar is within the height range of the front of the vehicle, it forms a vehicle-stopping state; when the stop bar is above the roof of the vehicle or below the ground of the transition area 520, it forms a yielding state. As another example, the vehicle stopper 100 can use a laterally movable stop bar, which can be slidably installed on the transverse guide rail on the ground of the transition area 520. When it moves laterally between the parking platform 550 and the work area door 530, it forms a vehicle-stopping state. A buffer element, such as an air cushion or rubber, can be provided on the stop bar to prevent the stop bar from damaging the vehicle.

[0044] Furthermore, the inventors astutely discovered a connection between the states of the vehicle stopper 100 and the entrance / exit gate 510: when the entrance / exit gate 510 is open, it indicates that a driver is storing or retrieving a vehicle in the transition area 520, and the vehicle may overshoot the parking platform 550; in this case, the vehicle stopper 100 needs to be in a stopping state. When the entrance / exit gate 510 is closed, it indicates that there is no driver in the transition area 520, and the transporter / transport robot needs to transport the vehicle from the transition area 520 to the work area 540, or vice versa, via the work area door 530; in this case, the vehicle stopper 100 needs to be in a yielding state to allow the transporter / transport robot to pass. Utilizing this connection, by setting up a linkage device 300, the vehicle stopper 100 and the entrance / exit gate 510 can be controlled simultaneously using a single drive device 200, thereby saving manufacturing costs for the parking equipment 10.

[0045] In this embodiment, the driving device 200 can be a motor, an electric / hydraulic push rod, etc. For example, the first action can be forward rotation, extension, etc., and the second action can be reverse rotation, retraction, etc. The linkage device 300 can be a linkage transmission mechanism such as rope drive, chain drive, gear drive, screw drive, or linkage drive, which simultaneously transmits the power of the driving device 200 to the vehicle stop 100 and the entrance / exit door 510, thereby simultaneously changing the state of the vehicle stop 100 and the entrance / exit door 510.

[0046] In this utility model's vehicle blocking system, by installing a vehicle blocker 100 with both blocking and yielding states on the front side of the parking platform 550, the system effectively prevents vehicles from crashing into the work area door 530 after exiting the parking platform 550, thus improving the safety of the parking equipment 10. Furthermore, by setting up a linkage device 300, the power of the drive device 200 is simultaneously transmitted to the vehicle blocker 100 and the entrance / exit door 510. Compared to having separate drive devices for the vehicle blocker 100 and the entrance / exit door 510, this reduces the cost of the drive devices and lowers the overall manufacturing cost of the parking equipment 10.

[0047] In some embodiments of the vehicle-stopping system of this utility model, such as Figure 1-3 and Figure 5 As shown, the vehicle stopper 100 includes a vertically arranged limiting guide rail and a horizontal stop bar 130.

[0048] The limiting guide rail is located in front of the over-length detection switch 413 of the parking device 10, and its upper end is located above the over-height detection switch 415 of the parking device 10. The limiting guide rail includes a left limiting guide rail 110 and a right limiting guide rail 120 arranged opposite each other, with the left limiting guide rail 110 located to the left of the left over-width detection switch 411 of the parking device 10, and the right limiting guide rail 120 located to the right of the right over-width detection switch 412 of the parking device 10. A lateral stop bar 130 is vertically connected between the left limiting guide rail 110 and the right limiting guide rail 120. When the lateral stop bar 130 is above the over-height detection switch 415, the vehicle stop 100 is in a yielding state; when the lateral stop bar 130 is at a first preset height, the vehicle stop 100 is in a blocking state. The first preset height is lower than the over-height detection switch 415.

[0049] The limiting guide rail can be fixedly installed on the ground of the conversion area 520 or on the side wall where the work area door 530 is located. The limiting guide rail is used to provide sufficient lateral support for the lateral stop bar 130, thereby preventing the impact of vehicles. The limiting guide rail is also used to guide and limit the raising and lowering of the lateral stop bar 130.

[0050] The front overhang detection switch 413 (usually a photoelectric switch) is used to detect whether the vehicle exceeds the distance from the front of the car to the front wheels (also known as the front overhang) for parking by the parking device 10. The overheight detection switch 415 (usually a photoelectric switch) is used to detect whether the vehicle exceeds the maximum height of the car for parking by the parking device 10. When the vehicle stop 100 is in the yielding state, the lateral stop 130 is higher than the overheight detection switch 415 to prevent scraping the top of the vehicle.

[0051] The first preset height is the distance between the lower edge of the transverse barrier 130 and the ground of the transition area 520. The first preset height can be set to 0.2 to 0.5 meters to block most types of passenger cars. Below 0.2 meters, it may scrape the vehicle chassis. Above 0.5 meters, it may scrape the vehicle hood. The distance between the upper edges of the transverse barrier 130 should be greater than 0.1 meters to effectively block parked vehicles. In some embodiments, the distance between the upper edges of the transverse barrier 130 is greater than 0.3 meters to block most types of parked vehicles and create a larger impact surface for better withstanding vehicle impacts.

[0052] In some embodiments of the vehicle-stopping system of this utility model, such as Figure 1-2 and Figure 4-5As shown, the drive device 200 includes a drive motor, and the linkage device 300 is connected to the horizontal stop bar 130 and the entrance / exit door 510 through rope drive and / or chain drive, so that when the drive motor rotates forward, it drives the entrance / exit door 510 to rise and causes the horizontal stop bar 130 to fall, and when the drive motor rotates in reverse, it drives the horizontal stop bar 130 to rise and causes the entrance / exit door 510 to fall.

[0053] In this embodiment, both the transverse stop 130 and the entrance / exit door 510 are lifting mechanisms. Specifically, when the drive motor rotates forward, the linkage device 300 transmits rotational power to the transverse stop 130 and the entrance / exit door 510, causing the entrance / exit door 510 to rise while simultaneously causing the transverse stop 130 to fall, thus creating an open door state and a vehicle-blocking state. When the drive motor rotates in reverse, the linkage device 300 transmits rotational power to the transverse stop 130 and the entrance / exit door 510, causing the transverse stop 130 to rise while simultaneously causing the entrance / exit door 510 to fall, thus creating a closed door state and a yielding state. This transmission mechanism has a simple structure, high reliability, and low cost.

[0054] In some embodiments of the vehicle-stopping system of this utility model, such as Figure 1-4 As shown, the linkage device 300 includes a first rope transmission mechanism 310 and a second rope transmission mechanism 320.

[0055] The first rope drive mechanism 310 includes a first drum 311, a first pulley 312, and a first steel rope 313. The first drum 311 is fixedly connected to the output shaft of the drive motor. The first pulley 312 is rotatably connected to the upper end of the limiting guide rail. One end of the first steel rope 313 is wound around the first drum 311, and the other end passes over the first pulley 312 and is fixedly connected to the transverse stop bar 130. The second rope drive mechanism 320 includes a second drum 321, a second pulley 322, and a second steel rope 323. The second drum 321 is coaxially fixedly connected to the first drum 311. The second pulley 322 is rotatably connected to the side wall where the entrance / exit door 510 is located. One end of the second steel rope 323 is wound around the second drum 321, and the other end passes over the second pulley 322 and is fixedly connected to the entrance / exit door 510.

[0056] In this embodiment, the linkage device 300 is used to transmit the lifting force, and the horizontal stop bar 130 and the entrance / exit door 510 can be lowered under their own gravity.

[0057] By appropriately setting the nominal diameters of the first drum 311 and the second drum 321, the ratio of the lifting speed of the horizontal stop bar 130 and the entrance / exit door 510 can be easily adjusted. For example... Figure 4As shown, since the lifting stroke of the horizontal stop bar 130 is less than that of the entrance / exit door 510, the first drum 311 can use a smaller nominal diameter, and the second drum 321 can use a larger nominal diameter, so that the horizontal stop bar 130 and the entrance / exit door 510 can be raised and lowered into position simultaneously.

[0058] This transmission mechanism has fewer parts, higher reliability, and lower cost.

[0059] In some embodiments of the vehicle-stopping system of this utility model, such as Figure 5 As shown, the linkage device 300 includes a first chain drive mechanism 330 and a second chain drive mechanism 340.

[0060] The first chain drive mechanism 330 includes a first sprocket 331, a second sprocket 332, and a third sprocket 333. The first sprocket 331 is fixedly connected to the output shaft of the drive motor, the second sprocket 332 is rotatably connected to the upper end of the limiting guide rail, and the third sprocket 333 is rotatably connected to the lower end of the limiting guide rail. The second sprocket 332 is a double-row sprocket. The first sprocket 331 is driven by the second sprocket 332 via the first circulating chain 334, and the second sprocket 332 is driven by the third sprocket 333 via the second circulating chain 335. A transverse stop bar 130 is fixedly connected to the second circulating chain 335. The second chain drive mechanism 340 includes a fourth sprocket 341, a fifth sprocket 342, and a sixth sprocket 343. The fourth sprocket 341 is coaxially fixedly connected to the first sprocket 331. The fifth sprocket 342 and the sixth sprocket 343 are both rotatably connected to the side wall where the entrance / exit door 510 is located, and are spaced vertically apart. The fifth sprocket 342 is a double-row sprocket. The fourth sprocket 341 is connected to the fifth sprocket 342 via the third circulating chain 344. The fifth sprocket 342 is connected to the sixth sprocket 343 via the fourth circulating chain 345. The entrance / exit door 510 is fixedly connected to the fourth circulating chain 345.

[0061] In this embodiment, due to the use of a circulating chain, the lifting and lowering of the transverse baffle 130 and the entrance / exit door 510 do not require their own gravity, resulting in higher reliability of the lifting and lowering operation.

[0062] In some embodiments of the vehicle-stopping system of this utility model, such as Figure 5-6 As shown, the drive device 200 includes a drive motor. The linkage device 300 includes a ball screw 351 mechanism 350 and a first chain drive mechanism 330.

[0063] The ball screw mechanism 350 includes a screw 351 and a screw nut 352. The screw 351 is horizontally positioned above the entrance / exit door 510. The screw 351 is connected to the drive motor via a belt drive mechanism 360, and the screw nut 352 is fixedly connected to the entrance / exit door 510. The belt drive mechanism 360 includes a main pulley 361 fixedly connected to the output shaft of the drive motor, a driven pulley 362 coaxially fixedly connected to the screw 351, and a circulating belt 363. The first chain drive mechanism 330 includes a first sprocket 331, a second sprocket 332, and a third sprocket 333.

The second sprocket 332 is a double-row sprocket. The first sprocket 331 is connected to the second sprocket 332 via the first circulating chain 334, and the second sprocket 332 is connected to the third sprocket 333 via the second circulating chain 335. The transverse stop bar 130 is fixedly connected to the second circulating chain 335.

[0064] In this embodiment, the entrance / exit door 510 is a horizontal sliding door. Compared to a lifting door, a horizontal sliding door is suitable for transition areas with lower heights.

[0065] The ball screw mechanism is a transmission mechanism with high reliability, long service life and high precision. It can efficiently convert the rotation of the drive motor into lateral linear motion, thereby realizing the lateral opening and closing of the entrance and exit door 510.

[0066] In some embodiments of the vehicle-stopping system of this utility model, such as Figure 6 As shown, the entrance / exit door 510 is a double door, the lead screws 351 are two screws with opposite directions of rotation and are coaxially fixedly connected, and there are also two lead screw nuts 352, which are fixedly connected to the left and right entrance / exit doors 510 respectively, so as to realize relative opening or relative closing.

[0067] In some embodiments of the vehicle-stopping system of this utility model, such as Figure 6 As shown, the first chain drive mechanism 330 consists of two sets, respectively located on the left and right sides of the parking platform 550. Specifically, two first sprockets 331 are respectively mounted at both ends of the drive shaft, two second sprockets 332 are respectively mounted at the upper ends of the left limit guide rail 110 and the right limit guide rail 120, and two third sprockets 333 are respectively mounted at the lower ends of the left limit guide rail 110 and the right limit guide rail 120. In this way, the horizontal stop bar 130 can be simultaneously raised and lowered from both ends via two second circulating chains 335, further improving the reliability of the raising and lowering of the horizontal stop bar 130.

[0068] In some embodiments of the vehicle-stopping system of this utility model, the drive device 200 includes a drive motor. The linkage device 300 includes a ball screw mechanism 351 and a first rope transmission mechanism 310.

[0069] The ball screw mechanism 350 includes a screw 351 and a screw nut 352. The screw 351 is laterally positioned on the upper side of the entrance / exit door 510. The screw 351 is connected to the drive motor via a belt drive mechanism 360, and the screw nut 352 is fixedly connected to the entrance / exit door 510. The belt drive mechanism 360 includes a main pulley 361 fixedly connected to the output shaft of the drive motor, a driven pulley 362 coaxially fixedly connected to the screw 351, and a circulating belt 363. The first rope drive mechanism 310 includes a first drum 311, a first rope pulley 312, and a first steel rope 313. The first drum 311 is coaxially fixedly connected to the main pulley 361, the first rope pulley 312 is rotatably connected to the upper end of the limit guide rail, one end of the first steel rope 313 is wound around the first drum 311, and the other end passes over the first rope pulley 312 and is fixedly connected to the transverse stop bar 130.

[0070] In some embodiments of the vehicle-stopping system of this utility model, such as Figure 2 As shown, the vehicle blocking system also includes an upper limit switch 421. The upper limit switch 421 is installed on the limit guide rail, and the upper limit switch 421 is triggered when the transverse stop 130 rises to the yielding state.

[0071] The upper limit switch 421 can be a limit switch, photoelectric switch, etc., used to generate a predetermined signal when the horizontal stop bar 130 is raised to the upper limit, to ensure that the horizontal stop bar 130 is raised to the upper limit and to prevent the vehicle from being scratched.

[0072] In some embodiments of the vehicle-stopping system of this utility model, such as Figure 1 As shown, the vehicle blocking system also includes a lower limit switch 422. The lower limit switch 422 is installed on the limit guide rail, and is triggered when the transverse stop bar 130 descends to the vehicle blocking state.

[0073] The lower limit switch 422 can be a limit switch, photoelectric switch, etc., used to generate a predetermined signal when the horizontal stop bar 130 is lowered to the lower limit, so as to ensure that the horizontal stop bar 130 is lowered to the lower limit and effectively prevent the vehicle from rushing out of the parking platform 550.

[0074] In some embodiments of the mechanical parking device of this utility model, such as Figure 1-2 and Figure 5 As shown, the mechanical parking equipment 10 includes an entrance / exit gate 510, a transfer area 520, and the aforementioned vehicle blocking system.

[0075] Mechanical parking equipment 10 can be vertical lifting parking equipment, planar moving parking equipment, lane stacking parking equipment, or handling robot parking equipment, etc.

[0076] By installing a vehicle blocking system in the transition zone 520, the system effectively prevents vehicles from crashing into the work area door 530 after exiting the parking platform 550, thus improving the safety of the parking equipment 10. Furthermore, by incorporating a linkage device 300 into the vehicle blocking system, the power of the drive unit 200 is simultaneously transmitted to the vehicle blocker 100 and the entrance / exit door 510. Compared to having separate drive units 200 for the vehicle blocker 100 and the entrance / exit door 510, this reduces the cost of the drive unit 200 and lowers the overall manufacturing cost of the parking equipment 10.

[0077] In some embodiments of the mechanical parking device of this utility model, such as Figure 1-2 and Figure 5 As shown, the mechanical parking system 10 also includes a work area 540, a transporter (not shown), and a work area door 530. The work area 540 has multiple parking spaces. The transporter is used to move vehicles parked on parking platforms 550 in the transition area 520 to the work area 540. A vehicle stopper 100 is located between the parking platform 550 and the work area door 530.
