Description

Technical Field

[0001] This invention relates to the field of automated mechanical equipment, and more specifically to the design of functional components for parking garages. Background Technology

[0002] With the development of modern society, the number of cars on the road is increasing year by year. The orderly parking of cars is a crucial aspect of car use. In many applications, such as shopping mall parking spaces, multi-level parking garages, smart parking spaces, and car wash parking spaces, users' vehicles need to be correctly parked before subsequent actions can be taken, such as using parking robots for repositioning and position correction.

[0003] Currently, when vehicles enter parking spaces in automated parking garages, they are often simply parked and locked. The vehicles' positions within the spaces are not precise, causing inconvenience for subsequent vehicle operations. For example, during operations, transport robots may damage the wheel hubs or frame of vehicles due to improper parking. Alternatively, irregular parking of vehicles during the lateral movement or lifting of the vehicle platform can cause instability or displacement.

[0004] For example, Chinese patent document with publication number CN202220971566.9 discloses a vertical circulating lifting parking device. The user parks the vehicle on the vehicle platform, which is equipped with blocks to position the vehicle's tires in the front and rear directions, thereby facilitating the parking of the vehicle in the correct position and providing convenience for subsequent operation procedures.

[0005] However, this technical solution has drawbacks. First, the stability of the protrusions is poor, and they are prone to displacement after prolonged use. Second, the vehicle platform has multiple functions, and the presence of the protrusions compromises the integrity of the platform and vehicle passability, causing inconvenience to other operations. Third, for some vehicles with low chassis, the chassis is easily damaged by mechanical parts when using automated lifting equipment. Summary of the Invention

[0006] The purpose of this invention is to provide a safety positioning device suitable for parking garages. It determines the parking position by positioning the vehicle's tires, has a good anti-collision effect, maintains the integrity of the vehicle platform and the vehicle's passability, and is less likely to cause damage to the chassis of the vehicle.

[0007] The present invention is achieved through the following technical solution: A safety positioning device suitable for parking garages, comprising a vehicle carrier plate with an opening, a back seat, a drive device, and a wheel baffle rotatably connected to the back seat and flipped under the drive of the drive device, the wheel baffle being installed at the opening, and the safety positioning device further comprising a height detection device for detecting the height of the vehicle chassis.

[0008] As a preferred embodiment of the present invention, the driving device includes a motor and a transmission assembly. The motor includes an output wheel, and the transmission assembly includes a chain connected to the output wheel, a connecting sprocket connected to the chain, and a rotating shaft connected to the connecting sprocket. The wheel baffle is connected to a multi-link device, and the rotating shaft drives the wheel baffle to rotate through the multi-link device.

[0009] As a preferred embodiment of the present invention, the multi-link device includes a first link and a second link, the rotating shaft is connected to the first link, the first link and the second link are connected by a first shaft, and the second link is connected to the wheel baffle by a second shaft.

[0010] As a preferred embodiment of the present invention, the wheel baffle includes a main baffle and a back plate connected to the back of the main baffle. The back plate has a rotation hole and a pulling hole. The connecting rod is connected to the pulling hole, and the back plate shaft passes through the rotation hole and is connected to the back seat.

[0011] As a preferred embodiment of the present invention, the wheel baffle includes a reinforcing side plate, the reinforcing side plate extending in a direction perpendicular to the main baffle, and the two are connected by a circular arc-shaped protective plate.

[0012] As a preferred embodiment of the invention, it also includes a pad tube, the backrest being mounted on the upper surface of the pad tube.

[0013] As a preferred embodiment of the present invention, it further includes an angle sensing device for detecting the rotation angle of the wheel baffle, the angle sensing device comprising a position sensor and a sensing element connected to the rotation shaft.

[0014] As a preferred embodiment of the present invention, the number of position sensors is two, which are mounted on a mounting plate, and the mounting plate is provided with an arc-shaped adjustment groove.

[0015] As a preferred embodiment of the present invention, the height detection device includes a swing assembly and a detection device. The swing assembly includes a base plate, a rotating device connected to the base plate, and a swing arm that flips relative to the base plate via the rotating device. The swing arm includes a main arm connected to the rotating device and two side arms connected to the main arm. A long shaft is connected to the side arms, and a roller is sleeved on the long shaft. The roller includes a main cylinder located between the two side arms and a side extension cylinder located outside the side arms.

[0016] As a preferred embodiment of the present invention, the diameter of the opening in the roller is larger than the radial diameter of the long shaft.

[0017] As a preferred embodiment of the present invention, the roller is a plurality of short cylindrical bodies independently mounted on the long shaft.

[0018] As a preferred embodiment of the present invention, the detection device is mounted on the base plate, and a sensor for cooperating with the detection device is mounted on the swing arm. The sensor includes an adjustment part for adjusting the extension length relative to the swing arm.

[0019] In summary, the present invention has the following beneficial effects:

[0020] 1. The wheel guards can be flipped up to block or flipped down to lie flat. When lying flat, they will not block the wheels, and the vehicle can continue to move forward normally.

[0021] 2. If the vehicle chassis is too low, the chassis will touch the height detection device to prevent low-chassis vehicles from entering.

[0022] 3. The wheel baffle can not only flip up and down, but also completely cover the opening after flipping, so that the surface of the entire vehicle platform is neat and does not affect the normal passage of vehicles.

[0023] 4. The entire drive unit can be hidden in the area below the opening, without interfering with the vehicle.

[0024] 5. A rotation center back plate shaft is set at a position with a small rotation radius, and a force-bearing point shaft is set at a position with a large rotation radius. The force is stable and the rotation of the wheel baffle is smooth.

[0025] 6. The backrest is designed with a small size, and there are pads underneath for reinforcement and elevation. On the one hand, this increases the support strength of the backrest; on the other hand, the force during the wheel baffle's flipping process is distributed on the small-sized backrest with a small lever arm, which is less likely to cause deformation of the backrest and improves the rotational stability of the wheel baffle.

[0026] 7. The end of the main baffle extends rearward with a reinforcing side plate, which serves to further increase the overall structural strength of the wheel baffle.

[0027] 8. The presence of the rounded guard plate makes it less likely for the vehicle tires to be damaged when they come into contact with the wheel guard plate during contact.

[0028] 9. On the one hand, the presence of the side expansion cylinder increases the width of the contact distance with the vehicle chassis, reducing the risk of false detections and missed detections. On the other hand, the vehicle chassis contacts the rollers, and the circular shape and rotation of the rollers make the contact relatively flexible, providing a certain degree of protection for the vehicle chassis.

[0029] 10. The rollers feature a segmented design, comprising multiple independent short cylinders. This segmented design reduces production costs and avoids the low tolerance for errors caused by coaxiality requirements, while also facilitating assembly.

[0030] 11. In addition, the segmented design makes the rotation of the rollers smoother and more convenient.

[0031] 12. The opening diameter of the roller's shaft hole is larger than the radial diameter of the long shaft. This setting can avoid wear and noise that occur between the two metal materials during rotation.

[0032] 13. The extension length of the sensing element is adjustable, thereby adjusting the starting angle of the swing arm to adapt to different detection heights. Attached Figure Description

Detailed Implementation

[0043] The present invention will be further described in detail below with reference to the accompanying drawings.

[0044] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0045] Example 1: A safety positioning device suitable for parking garages, which mainly comprises two components, namely... Figure 1 The wheel alignment device shown and Figure 5 The height detection device shown is used when a user drives their vehicle into the parking garage. The vehicle will first pass over this device. If the vehicle's chassis is too low, it will touch the device, which will then alert the user through standard methods such as flashing warning lights and sounding an alarm to prevent low-chassis vehicles from entering. Normally, when a vehicle enters the garage, its tires will be... Figure 1 The wheel alignment device acts as a guide, positioning the entire vehicle. This obstruction is mainly achieved by the wheel baffle 5. In this case, the wheel baffle 5 can be flipped up to block or flipped down to lie flat. When lying flat, it does not obstruct the wheels, and the vehicle can continue to move forward normally.

[0046] Specifically, such as Figure 1 and Figure 2 As shown, the vehicle includes a vehicle carrier 91, on which the vehicle drives when it enters the garage. An opening 92 is provided on the vehicle carrier 91, and the space below the opening 92 is used to install the drive unit 4. A backrest 93 is also installed in this space; this component can be considered a fixed part, with the wheel wells rotatably connected to it and tilting up and down under the drive of the drive unit 4.

[0047] like Figure 2 and Figure 3 As shown, the power comes from motor 41. When motor 41 operates, output wheel 411 rotates. This rotation is achieved through chain 421 and connecting sprocket 422, which drives rotating shaft 423 to rotate. Rotating shaft 423, via a multi-link device 424 as a transmission component, drives wheel baffle 5 to rotate. Multi-link device 424 includes connecting rod 1 4241 and connecting rod 2 4242. Rotating shaft 423 is connected to connecting rod 1 4241. Connecting rod 1 4241 and connecting rod 2 4242 are connected via shaft 1 4243. Connecting rod 2 4242 and wheel baffle 5 are connected via shaft 2 4244. Wheel baffle 5 includes main baffle 51, with a back plate 55 on its back side. Back plate 55, as a connecting component, has a pull hole 552 at its top and a rotation hole 551 at its bottom. Shaft 2 4244 is connected to back seat 93 via pull hole 552, and back plate shaft 95 is connected to back seat 93 via rotation hole 551.

[0048] Through this transmission structure, the wheel baffle 5 can not only flip up and down, but also completely cover the opening 92 after flipping, resulting in a smooth surface of the entire vehicle platform 91 and not affecting the normal passage of vehicles. Furthermore, the entire drive unit 4 can be hidden within the area below the opening 92, without interfering with the vehicle. A rotation center backplate shaft 95 is set at a position with a small flip radius, while a force-bearing point shaft 4242 is set at a position with a large flip radius, ensuring stable force distribution and high smoothness of wheel baffle 5 flipping.

[0049] In this case, to further improve the rotational stability of the wheel baffle 5, the backrest 93 was designed with a small size, and a pad tube 94 for reinforcement and elevation was set underneath it. This design, on the one hand, increases the support strength of the backrest 93, and on the other hand, the force during the rotation of the wheel baffle 5 is on the small-sized backrest 93 with a small lever arm, which is less likely to cause deformation of the backrest 93, thus improving the rotational stability of the wheel baffle 5.

[0050] like Figure 2 As shown, a reinforcing side plate 53 extends rearward from the end of the main baffle 51, which further increases the overall structural strength of the wheel baffle 5. The two are connected by an arc-shaped protective plate 52, making it less likely for the vehicle tire to be damaged when it comes into contact with the wheel baffle 5.

[0051] The height detection device, which includes a swing assembly 2, is located near the garage entrance. Figure 6 and Figure 8 As shown, the device includes a base plate 21, which can be mounted on the ground using common fasteners or on a vehicle platform 91, and is considered a stationary component. A rotating device 22 is mounted on the upper surface of the base plate 21. The rotating device 22 can be a hinge structure, comprising a pivot 222 and a flap 221 connected to the pivot 222. The upper surface of the flap 221 is connected to a swing arm 26, allowing the swing arm 26 to rotate around the pivot 222. A torsion spring 223 is fitted around the pivot 222, providing elastic cushioning for the rotation and reset of the swing arm 26. The number of rotating devices 22 can be adjusted by the user; in this case, there are two, installed along the length of the base plate 21, i.e., along the axial direction of the long shaft 24.

[0052] like Figure 7 As shown, the swing arm 26 comprises two parts: a main arm 261 and a side arm 262 connected thereto. In this embodiment, the two are vertically connected. The two side arms 262 have connecting holes 263 through which the long shaft 24 passes.

[0053] The roller 25 passes through the long shaft 24. In this embodiment, the roller 25 is a segmented design, comprising multiple independent short cylinders. The segmented design reduces production costs and avoids the low tolerance caused by coaxiality requirements, facilitating assembly. In addition, the segmented design makes the rotation of the roller 25 smoother and more convenient.

[0054] In this case, roller 25 comprises two areas, such as Figure 7 As shown, these are the main tube 251 between the two side arms 262 and the side extension tube 252 in the region outside the side arms 262.

[0055] When a vehicle passes by, if the vehicle chassis is too low, it will touch the roller 25, causing the swing arm 26 to rotate. This rotation process is detected by the detection device 3 installed on the base plate 21, thereby triggering a signal.

[0056] In this case, on the one hand, the presence of the side extension tube increases the width of the contact distance with the vehicle chassis, reducing the risk of false positives and false negatives. On the other hand, the vehicle chassis contacts the roller 25, and the circular shape and rotation of the roller 25 make the contact relatively flexible, providing a certain degree of protection for the vehicle chassis.

[0057] In this embodiment, the opening diameter of the shaft hole of the roller 25 is larger than the radial diameter of the long shaft 24, which allows the roller 25 to fit loosely on the long shaft 24. When the car chassis touches the roller 25, the roller 25 rotates relative to the long shaft 24. The long shaft 24 can be fixedly connected to the swing arm 26, that is, during the rolling process, the roller 25 rotates while the long shaft 24 does not rotate. Since the long shaft 24 and the swing arm 26 are often made of metal, while the roller 25 is made of soft material, this arrangement can avoid wear and noise that occur between the two metal materials during rotation.

[0058] like Figure 7 and Figure 8 As shown, the detection device 3 is mounted on the base plate 21. The sensing element 23 is mounted on the main arm 261 and cooperates with the detection device 3. The detection device 3 can be either a contact type or a photoelectric type. In this embodiment, a contact type limit switch is used, which provides more stable and accurate detection. The extension length of the sensing element 23 can be adjusted, thereby adjusting the starting angle of the swing arm 26 to adapt to different detection heights. In this embodiment, the sensing element 23 can be a bolt, which achieves the adjustment of the extension length through a threaded connection with the swing arm 26.
