Description

Technical Field

[0001] This utility model relates to the field of parking equipment technology, specifically to a vehicle platform entrance / exit widening mechanism applied to parking equipment and flat parking spaces. Background Technology

[0002] Parking equipment is widely used in China, with lift-and-slide parking systems and simple lift-and-slide systems with multiple parking spaces accounting for over 70% of the market share. These two types of parking equipment are simple in design and cost-effective, but their main problem is the limited width of the entrance and exit, which severely affects the convenience of parking and retrieving vehicles. This problem has existed since the introduction of this type of parking equipment, and it has become more prominent with the increasing width of passenger cars. A few years ago, the industry proposed a technical solution called "secondary lateral movement," which can help with the convenience of parking and retrieving vehicles to some extent, but it still has the following problems: First, the increase in entrance and exit width is limited (usually only half the width of the pillars, about 75mm); second, the secondary lateral movement of the car platform affects all parking and retrieval actions, impacting the operating efficiency of the equipment; third, the original lateral movement detection and positioning method of the equipment needs to be modified. In addition, many surface parking spaces (especially indoor parking spaces) are narrow, also resulting in insufficient entrance and exit dimensions for parking and retrieval. Therefore, finding better technical solutions to truly address the limitations of existing technologies for lift-and-slide parking systems, simple lift-and-slide parking systems with multiple parking spaces, and flat parking spaces, which have limited entrance and exit widths, remains an urgent problem for the industry. Summary of the Invention

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the shortcomings of existing technologies such as lifting and traversing parking equipment, simple lifting parking equipment with multiple parking spaces, and flat parking spaces, which have limited entrance and exit width and seriously affect the storage and retrieval of vehicles. It provides an innovative solution that significantly increases the entrance and exit width on the driver's side of the vehicle storage and retrieval in a simple and effective way, improves the convenience of using the equipment, and enhances the competitiveness of related complete products.

[0004] To address the aforementioned problems, this utility model provides a vehicle platform entrance / exit widening mechanism, characterized in that it is applied to parking equipment and surface parking spaces, comprising: The vehicle platform is a level platform with its longitudinal centerline perpendicular to the lane centerline, and it supports vehicles on top. The levelness refers to the fact that the upper plane of the vehicle platform's driving passage and the four wheel-bearing areas are all on the same horizontal plane. The four wheel-bearing areas refer to the areas where the four wheels of the vehicle are located when the vehicle platform is stationary and when it makes lateral displacement.

[0005] The displacement unit includes at least two sets of drive components; the drive components include a self-drive unit and a power unit.

[0006] The self-drive unit includes several drive rollers horizontally arranged in the area carrying the wheel, with their center lines parallel to the longitudinal center line of the vehicle body. The center distance between any two adjacent drive rollers is less than the width of the wheel. The self-drive unit also includes several sets of self-drive transmission pairs, with any two adjacent drive rollers connected through one set of self-drive transmission pairs. When any drive roller rotates, it drives all the drive rollers to rotate synchronously and in the same direction.

[0007] The power unit is mounted on the vehicle panel and includes a motor reducer and a power transmission pair. The driving component of the power transmission pair is fixedly mounted on the output shaft of the motor reducer, and the driven component is coaxially mounted with any of the drive rollers and rotates synchronously.

[0008] The rotation of the motor reducer drives all the drive rollers to rotate through the power transmission pair and the self-drive transmission pair, thereby driving the vehicle, which is stationary on the vehicle platform, to make a lateral displacement to the left or right.

[0009] A photographing device is mounted on a frame above the vehicle platform, with the shooting direction facing the vehicle platform and the shooting range including the outer frame area of ​​the vehicle platform, to obtain the relative position information of the vehicle on the vehicle platform.

[0010] The selection key is located on the operation box. The operator determines the vehicle body that needs to be laterally displaced and the direction of the lateral displacement by operating the selection key.

[0011] The control unit is connected to the displacement unit, the imaging device, and the selection key.

[0012] The single-run implementation of the technical solution described in this application includes the following steps: First, the operator determines the vehicle body that needs lateral displacement and the direction of the lateral displacement by operating the selection key, and the relevant information is sent to the control unit.

[0013] Second, the control unit instructs the displacement unit to operate based on the information, and instructs the photographing device to enter working mode. The displacement unit drives the vehicle to move in a specified lateral direction, and the photographing device takes pictures of the vehicle body at preset photographing intervals, sending the relevant image information to the control unit.

[0014] Third, the control unit compares the image information containing the vehicle outline and the vehicle panel outline with the pre-set image information of the vehicle displacement position.

[0015] Fourth, when the vehicle is in position, the control unit instructs the displacement unit to stop operating and the camera to stop working.

[0016] Fifth, the above operation results in the vehicle platform that needs to access the vehicle gain an additional entrance and exit width dimension on the driver's side.

[0017] Furthermore, according to the aforementioned vehicle platform entrance / exit widening mechanism, the driving assembly comprises two sets, and the displacement unit further comprises two sets of follower assemblies; the two sets of driving assemblies are respectively disposed in two load-bearing wheel areas on one longitudinal side of the vehicle platform, and the two sets of follower assemblies are respectively disposed in two load-bearing wheel areas on the other longitudinal side of the vehicle platform.

[0018] Furthermore, according to the aforementioned vehicle platform entrance / exit widening mechanism, the driving assembly comprises two sets, and the displacement unit further comprises two sets of follower assemblies; the two sets of driving assemblies are respectively arranged in two load-bearing wheel areas diagonally distributed with respect to the center point of the vehicle platform, and the two sets of follower assemblies are respectively arranged in two other load-bearing wheel areas diagonally distributed with respect to the center point of the vehicle platform.

[0019] Furthermore, according to the aforementioned vehicle platform entrance / exit widening mechanism, the driving assembly comprises four sets, respectively disposed in the four wheel-bearing areas of the vehicle platform.

[0020] Optionally, according to the aforementioned vehicle platform entrance / exit widening mechanism, the following component includes a plurality of horizontally continuous following rollers, the center line of which is parallel to the longitudinal center line of the vehicle platform, and the center distance between any two adjacent following rollers is less than the width of the wheel.

[0021] Optionally, according to the aforementioned vehicle platform entrance / exit widening mechanism, the power transmission pair is characterized by adopting one of the following two structures: In the first method, the power transmission pair includes a first sprocket, a second sprocket, and a transmission chain; the first sprocket is the driving component, the second sprocket is the driven component, and the transmission chain is a roller chain, a toothed chain, or a toothed belt, which meshes with the first sprocket and the second sprocket.

[0022] Method 2: The power transmission pair includes a coupling; one end of the coupling is the driving component, and the other end is the driven component.

[0023] Optionally, according to the aforementioned vehicle platform entrance / exit widening mechanism, the self-driven transmission pair includes a main gear, an intermediate gear, and a driven gear; the plurality of driving rollers are arranged continuously, with one side defined as the starting side and the other side as the ending side.

[0024] The first drive roller on the starting side is defined as the first master roller; the drive roller adjacent to the first master roller in the direction of the ending side is the first slave roller, the first slave roller also serves as the second master roller, and the drive roller adjacent to the second master roller is the second slave roller; the arrangement of the subsequent master rollers and slave rollers is similar.

[0025] The self-driven transmission pair that drives the first driven roller to rotate is defined as the first self-driven transmission pair, and the self-driven transmission pair that drives the second driven roller to rotate is defined as the second self-driven transmission pair; the arrangement of the subsequent self-driven transmission pairs is similar.

[0026] The first self-driven transmission pair is configured as follows: the main gear is coaxially mounted and rotates synchronously with the first main roller, the driven gear is coaxially mounted and rotates synchronously with the first driven roller, and the intermediate gear is positioned between the main gear and the driven gear, meshing with both the main gear and the driven gear respectively. The second self-driven transmission pair is configured as follows: the driven gear of the first self-driven transmission pair serves as the main gear of the second self-driven transmission pair, the driven gear of the second self-driven transmission pair is coaxially mounted and rotates synchronously with the second driven roller, and the intermediate gear is positioned between the main gear and the driven gear, meshing with both the main gear and the driven gear respectively. The configuration methods for the main gear, intermediate gear, and driven gear of subsequent self-driven transmission pairs are similar.

[0027] Optionally, according to the aforementioned vehicle platform entrance / exit widening mechanism, the self-drive transmission pair includes a main sprocket, a driven sprocket, and a chain; the chain is a roller chain, a toothed chain, or a toothed belt; the plurality of drive rollers are arranged continuously, with one side defined as the starting side and the other side as the ending side.

[0028] The first drive roller on the starting side is defined as the first master roller; the drive roller adjacent to the first master roller in the direction of the ending side is the first slave roller, the first slave roller also serves as the second master roller, and the drive roller adjacent to the second master roller is the second slave roller; the arrangement of the subsequent master rollers and slave rollers is similar.

[0029] The self-driven transmission pair that drives the first driven roller to rotate is defined as the first self-driven transmission pair, and the self-driven transmission pair that drives the second driven roller to rotate is defined as the second self-driven transmission pair; the arrangement of the subsequent self-driven transmission pairs is similar.

[0030] The self-driven transmission pair that drives the first driven roller to rotate is defined as the first self-driven transmission pair, and the self-driven transmission pair that drives the second driven roller to rotate is defined as the second self-driven transmission pair; the arrangement of the subsequent self-driven transmission pairs is similar.

[0031] The first self-driven transmission pair is configured such that the main sprocket, driven sprocket, and chain are installed coaxially with the first main roller and rotate synchronously, the driven sprocket is installed coaxially with the first driven roller and rotates synchronously, and the chain meshes with the main sprocket and driven sprocket. The second self-driven transmission pair is configured such that the main sprocket is installed coaxially with the second main roller and rotates synchronously, the driven sprocket is installed coaxially with the second driven roller and rotates synchronously, and the chain meshes with the main sprocket and driven sprocket. The configuration of the main sprocket, driven sprocket, and chain for subsequent self-driven transmission pairs follows the same principle.

[0032] Optionally, according to the aforementioned vehicle platform entrance / exit widening mechanism, the self-drive transmission pair includes a main sprocket, a driven sprocket, and a chain; the chain is a roller chain, a toothed chain, or a toothed belt.

[0033] The drive assembly also includes several follower rollers arranged horizontally with their centerlines parallel to the longitudinal centerline of the vehicle body. The follower rollers are located between two drive rollers. The drive rollers and the follower rollers are arranged alternately, with one side defined as the starting side and the other side as the ending side.

[0034] The first drive roller on the starting side is defined as the first master roller. Moving towards the ending side, the follower roller adjacent to the first master roller is the first follower roller, and the drive roller adjacent to the first follower roller is the first slave roller. The first slave roller also serves as the second master roller, the follower roller adjacent to the second master roller is the second follower roller, and the drive roller adjacent to the second follower roller is the second slave roller. The arrangement of the master roller, follower roller, and slave roller is then deduced in the same manner.

[0035] The self-driven transmission pair that drives the first driven roller to rotate is defined as the first self-driven transmission pair, and the self-driven transmission pair that drives the second driven roller to rotate is defined as the second self-driven transmission pair; the arrangement of the subsequent self-driven transmission pairs is similar.

[0036] The first self-driven transmission pair is configured such that the main sprocket, driven sprocket, and chain are installed coaxially with the first main roller and rotate synchronously, the driven sprocket is installed coaxially with the first driven roller and rotates synchronously, and the chain meshes with the main sprocket and driven sprocket. The second self-driven transmission pair is configured such that the main sprocket is installed coaxially with the second main roller and rotates synchronously, the driven sprocket is installed coaxially with the second driven roller and rotates synchronously, and the chain meshes with the main sprocket and driven sprocket. The configuration of the main sprocket, driven sprocket, and chain for subsequent self-driven transmission pairs follows the same principle.

[0037] The difference between this technical solution and the previous one is that this technical solution provides a follower roller between every two drive rollers, which increases the center distance between the two drive rollers without affecting the load-bearing effect.

[0038] As is common sense, for sprocket / chain drives (especially roller chain drives), there should be a reasonable center distance between the two sprockets; if it is too small, it will affect the smoothness of the transmission. Therefore, the advantage of this technical solution is that it increases the center distance between the two sprockets of the self-drive transmission pair, which helps to improve the smoothness of the transmission between the two sprockets of the self-drive transmission pair.

[0039] Optionally, according to the aforementioned vehicle platform entrance / exit widening mechanism, the selection key is a selection key for the vehicle platform involved in storing or retrieving the vehicle. After the operator selects the vehicle platform involved in storing or retrieving the vehicle, the control unit automatically determines the vehicle platform that needs to be moved laterally and the direction of the vehicle's lateral displacement.

[0040] The key feature of this solution is that it takes into account the default parking system, where the vehicle's driver's side is positioned on the platform after it has entered and is parked. The purpose of widening the platform's entrance / exit is to widen the driver's side entrance / exit for platforms used for storing and retrieving vehicles. Therefore, after the operator selects the platform involved in storing or retrieving a vehicle, the control unit automatically selects the platform requiring lateral movement (actually the platform adjacent to the driver's side of the platform) and the direction of lateral movement (vehicles parked on the platform adjacent to the driver's side of the platform will move laterally away from the driver's side of the platform).

[0041] Optionally, according to the aforementioned vehicle platform entrance / exit widening mechanism, the selection key includes a button for selecting the vehicle platform to be moved laterally, and also includes directional keys; the directional keys include a left-moving key, a right-moving key, and a center key; the operator determines the vehicle platform to be moved laterally by using the button, and then determines the lateral movement direction of the vehicle by using the directional keys.

[0042] The key feature of this solution is that the operator first uses the buttons on the control box to determine the vehicle platform that needs to be moved laterally, and then uses the directional keys to determine the lateral movement direction of the wheels. The purpose of selecting the directional keys is as follows: the left key moves the vehicle laterally to the left, the right key moves the vehicle laterally to the right, and the center key moves the vehicle laterally to the center position.

[0043] Furthermore, according to the aforementioned vehicle platform entrance / exit widening mechanism, the function of the control unit is embedded inside the operation box; or, embedded inside the control system of the equipment.

[0044] It is obvious that the function of the control unit of this utility model can be embedded in the operation box or in the control system of the equipment. For upgrading and retrofitting old equipment and for application in flat parking spaces, the cost of embedding the function of the control unit in the operation box is relatively lower.

[0045] Furthermore, according to the aforementioned vehicle platform entrance / exit widening mechanism, the vehicle platform is characterized in that it is a vehicle platform installed on the ground floor.

[0046] The vehicle platform set on the ground floor refers to the ground floor lateral vehicle platform for lifting and traversing parking equipment; it also refers to the ground floor vehicle platform for simple lifting parking equipment with multiple parking spaces and for flat parking spaces.

[0047] This solution takes into account the following reasons: First, the lifting platform of the lift-and-slide parking equipment and the simple lift-and-slide parking equipment with multiple parking spaces is obstructed by the traction chain, significantly reducing the space available for lateral movement; Second, if the lift platform needs to store or retrieve vehicles, the lateral movement of vehicles parked on the ground-level platform adjacent to the driver's side of the lift platform can achieve the purpose of widening the entrance / exit. Therefore, installing the relevant widening mechanism only on the ground-level platform is a reasonable option.

[0048] The present invention provides a vehicle platform entrance / exit widening mechanism applicable to lifting and traversing parking equipment, simple lifting parking equipment with multiple parking spaces, and flat parking spaces. Compared with the closest prior art, it has the following advantages.

[0049] 1. It can significantly increase the width of the entrance / exit on the driver's side.

[0050] As mentioned above, the "secondary lateral movement" technology is limited by the lateral movement over-limit setting in the system, typically only achieving an increase in width of about 75mm (the maximum width of the parking equipment column is usually only 150mm, and the lateral movement over-limit switch can only be placed in the middle of the column at most). This invention, assuming a parking space width of 2400mm (this is a relatively small size required for parking equipment; although industry standards allow for parking spaces with widths as low as 2350mm for small cars, this is rarely used in practice), and a parked vehicle width of 2000mm (this is already the standard for extra-large vehicles), then compared to a normal parking space in the middle, there is 200mm of usable space on each side. In other words, this invention can achieve at least a 200mm increase in width, more than twice that of existing "secondary lateral movement" technologies.

[0051] 2. After adopting the "secondary lateral movement" technical solution, the lateral movement of the vehicle platform will widen the tunnel and create a pit that will affect the driver's entry and exit. Therefore, it is necessary to add a mechanism to fill the pit. However, since the technical solution of this utility model does not involve the lateral movement of the vehicle platform, it does not have the above defects.

[0052] 3. The "secondary lateral movement" technology will cause safety issues to all parking spaces during operation, thus necessitating the cessation of all parking space storage and retrieval operations, resulting in reduced equipment operating efficiency. In contrast, the operation of this utility model only involves one parking platform, without affecting the storage and retrieval operations of other parking spaces or the scheduling of parking platforms, and has no impact on the operating efficiency of the equipment.

[0053] Therefore, the present invention has significant differences compared with the prior art and has significant improvements in performance.

[0054] It should be further noted that the technical solution of this utility model can be applied not only to new products, but also to the upgrading and transformation of existing equipment and the performance improvement of flat parking spaces, thus further expanding the scope of application.

Detailed Implementation

[0060] 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.

[0061] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0062] like Figures 1 to 3 As shown, these are existing products ( Figure 1 ), "secondary transverse movement" technical solution ( Figure 2 ) and the technical solution of this utility model ( Figure 3 A schematic diagram of the width variation of the vehicle platform entrance and exit (a plan view). Figures 1 to 3 All parking spaces have three bays (bay 1 01, bay 2 02, and bay 3 03); above each bay are parking platforms (platform 1 21, plaque 2 22, and plaque 3 23), the outline of which is shown in the diagram; vehicles (vehicle 1 11, vehicle 2 12, and vehicle 3 13) are parked on these platforms, their outlines also shown in the diagram. The right side of each vehicle's outline is a thick solid line, indicating the driver's side.

[0063] Figures 1 to 3 All are assumed to be: parking space center distance 2400mm, vehicle platform width 2350mm, and vehicle width 2000mm.

[0064] Figures 1 to 3 It is assumed that vehicle 11, which is parked on platform 21, is ready to be retrieved; moreover, platform 21 is a lifting platform and cannot be moved laterally.

[0065] from Figure 1 As can be seen, due to the lack of "entrance / exit widening" technology in existing products, the center lines 31A of parking space one, 31B of vehicle platform one, and 31C of vehicle one are always on a straight line; similarly, the center lines 32A of parking space two, 32B of vehicle platform two, 32C of vehicle two, and 33A of parking space three, 33B of vehicle platform three, and 33C of vehicle three are all on a straight line; the theoretical width of the entrance / exit on the driver's side of vehicle one 11 is 400mm.

[0066] Figure 2As shown, a "secondary lateral movement" technique is employed. Vehicle platform 22, carrying vehicle platform 22, and vehicle platform 3, carrying vehicle platform 33, simultaneously shift laterally to the right. This lateral movement causes the center lines 32B and 32C of vehicle platform 2 to shift from the center line 32A of parking space 2, and the center lines 33B and 33C of vehicle platform 3 to shift from the center line 33A of parking space 3. The displacement distance is 75mm, resulting in an entrance / exit width of 400 + 75 = 475mm for the driver's side of vehicle platform 11. It must be noted that during the "secondary lateral movement," all platforms except vehicle platform 11 undergo lateral movement.

[0067] Figure 3 As shown, the entrance / exit widening technology of this utility model is adopted. Under the drive of the displacement unit, vehicle 12 on vehicle platform 22 moves laterally to the right without moving vehicle platform 22 (this lateral displacement causes the center line 32C of vehicle 12 to shift from the center line 32B of vehicle platform 2 and the center line 32A of parking space 2). Theoretically, the displacement distance is 200mm, making the entrance / exit width on the driver's side of vehicle 11 400+200=600mm. It can be seen that the operation of the entrance / exit widening technology of this utility model only involves one vehicle platform, and this vehicle platform does not need to move; only the vehicle moves.

[0068] As can be seen from the above, the present invention can significantly increase the width of the driver's side entrance and exit of a vehicle, and completely solve the problem of narrow entrances and exits in the prior art.

[0069] like Figure 4 The diagram shows three ways of arranging the displacement unit in the technical solution of this utility model (in plan view).

[0070] in: The leftmost plan view shows a displacement unit comprising two sets of drive assemblies and two sets of follower assemblies. The two sets of drive assemblies are respectively positioned in two load-bearing wheel areas on one side of the longitudinal direction of the vehicle platform, and the two sets of follower assemblies are respectively positioned in two load-bearing wheel areas on the other side of the longitudinal direction of the vehicle platform. As shown in the figure, the two sets of drive assemblies 40 are respectively positioned in two load-bearing wheel areas on the left side of the longitudinal direction of the vehicle platform 30, and the two sets of follower assemblies 41 are respectively positioned in two load-bearing wheel areas on the right side of the longitudinal direction of the vehicle platform 30. Clearly, swapping the positions of the two sets of drive assemblies 40 and the two sets of follower assemblies 41 achieves the same effect.

[0071] The central planar view shows a displacement unit comprising two sets of drive components and two sets of follower components. The two sets of drive components are respectively positioned in two wheel-bearing areas diagonally opposite the center point of the vehicle platform, and the two sets of follower components are respectively positioned in two other wheel-bearing areas diagonally opposite the center point of the vehicle platform. As shown in the figure, the two sets of drive components 40 are positioned at the upper left and lower right corners of the vehicle platform 30, respectively, and the two sets of follower components 41 are positioned at the upper right and lower left corners of the vehicle platform 30, respectively. Clearly, swapping the positions of the two sets of drive components 40 and the two sets of follower components 41 achieves the same effect.

[0072] The rightmost plan view shows that the displacement unit includes four sets of drive components 40, which are respectively set in the four wheel-bearing areas of the vehicle plate 30. Example

[0073] Figure 5 The diagram shown is a top view of the first embodiment of the self-driven unit in the present invention.

[0074] Comparing the above content Figure 5 As can be seen, the self-driven transmission pair in this embodiment includes a main gear, an intermediate gear, a driven gear, and a driving roller arranged continuously.

[0075] As shown in the figure, the drive rollers are arranged horizontally and continuously from left to right, with the left side as the starting side and the right side as the ending side. The drive rollers shown in the figure are 61, 62, 63, 64, and 65.

[0076] As shown in the figure, bearing seats 30 are provided at the shaft ends of both the drive roller and the intermediate roller.

[0077] Comparing the above content Figure 5 It can be known that: The leftmost drive roller 61 is defined as the first master roller, the drive roller 62 adjacent to the first master roller (i.e., drive roller 61) is the first slave roller, the first slave roller (i.e., drive roller 62) also serves as the second master roller, and the drive roller 63 adjacent to the second master roller (i.e., drive roller 62) is the second slave roller; the arrangement of the master rollers and slave rollers thereafter is similar.

[0078] The self-driven transmission pair that drives the first driven roller (i.e., drive roller 2 62) to rotate is defined as the first self-driven transmission pair 21, and the self-driven transmission pair that drives the second driven roller (i.e., drive roller 3 63) to rotate is defined as the second self-driven transmission pair 22; the arrangement of the subsequent self-driven transmission pairs is similar.
