Description

Technical Field

[0001] The invention relates to three-dimensional parking equipment, in particular to a wheel positioning device for a vehicle entrance hall of a three-dimensional garage. Background Art

[0002] With the development of society and the improvement of people's living standards, motor vehicles have become the main means of transportation for people to travel. With the increase in the number of vehicles, parking spaces are tight. In order to solve the parking problem, large parking lots must be built. Since large parking lots require a large area of ​​land, this not only increases the cost of building parking lots, but also increases the land area, especially in densely populated cities. Therefore, stereo parking garages are becoming more and more widely used.

[0003] In order to ensure parking safety, existing three-dimensional parking garages are generally equipped with an entrance hall with a parking rack. Users drive the vehicle into the entrance hall through the outer door and park it on the parking rack before leaving. The inner door of the entrance hall opens and the transporter transports the vehicle to the interior of the three-dimensional parking garage.

[0004] The wheel alignment device is a key component of the entrance hall of a three-dimensional parking garage. It is mainly used to bear the vehicle load and provide accurate wheel position during the vehicle storage and retrieval process to ensure that the vehicle is safely and stably lifted and lowered by the intelligent transporter. Therefore, the wheel alignment mechanism is required to have high strength and provide accurate vehicle position during the storage and retrieval process. Since the vehicle intelligent transporter requires accurate position of the vehicle wheels and the wheels are easy to correct when the vehicle is centered, wheel alignment and position detection are very important and are also important technical difficulties.

[0005] The wheel alignment device in the prior art generally adopts round steel or V-shaped structure welded in the parking position. The driver parks the car by feeling that the wheel hits the round steel or falls into the V-shaped structure. Due to the difference in individual perception, the amount of parking spaces varies greatly. When the vehicle intelligent transporter pushes the wheel to straighten it, the wheel may be punctured or out of position, resulting in difficulty in storage and retrieval, and there is a risk of vehicle damage. Summary of the invention

[0006] The purpose of the present invention is to provide a wheel positioning device for a parking entrance hall of a three-dimensional parking garage, so as to solve the problems existing in the prior art and improve the smoothness and safety of the operation of the three-dimensional parking garage.

[0007] The objective of the present invention is achieved in this way: a wheel positioning device for a vehicle entrance hall of a stereoscopic parking garage comprises a mounting base plate, a hinge device is arranged in the middle of the mounting base plate, inclined floating wheel groups are symmetrically arranged on the front and rear sides, the hinge device comprises a hinge seat and a hinge plate, the hinge seat is fixed on the mounting base plate, one side of the hinge plate is rotatably connected to the hinge seat, and the other side is fixedly connected to the adjacent floating wheel group, an elastic support for the wheel group is arranged on the mounting base plate, a detection device is arranged at the bottom of the mounting base plate, a detection trigger device is connected to the bottom of the floating wheel group, an inverted L-shaped limit plate is connected to the outer side of the floating wheel group, a notch is arranged on the mounting base plate corresponding to the setting position of the limit plate, the horizontal section of the limit plate is fixedly connected to the floating wheel group, a horizontal limit rod is arranged on the outer side of the lower end of the vertical section of the limit plate, and a limit screw matched with the limit rod is arranged on the mounting base plate.

In order to ensure the accuracy of wheel position detection, the floating wheel groups on the front and rear sides are equipped with detection devices and detection trigger devices, which are provided to the system to judge the wheel position state, so that the control system can determine that the wheel is parked in place only when the front and rear two sets of detection devices detect the pressure signal.

[0009] The wheel alignment device for the entrance hall of a three-dimensional garage of the present invention forms a V-shaped vehicle wheel parking structure through the front and rear two floating wheel groups. The wheel group elastic support and the wheel group limit rod provide floating space for the floating wheel group. The detection devices of the front and rear two floating wheel groups provide the position status of the front and rear sides of the same wheel, which helps to accurately and effectively determine the position status of the vehicle wheels. The overall position of the vehicle can be controlled through the system, thereby improving the efficiency of vehicle storage and retrieval and the overall safety of the vehicle. In summary, the wheel alignment device for the entrance hall of a three-dimensional garage of the present invention can effectively solve the efficiency and safety of vehicle storage and retrieval in the entrance hall of an existing three-dimensional garage.

[0010] As a further improvement of the present invention, the wheel group elastic support includes a mounting sleeve, a compression spring and an annular convex top sleeve. The top of the mounting sleeve is fixedly connected to the bottom surface of the mounting base plate. The compression spring is installed in the mounting sleeve. The annular convex top sleeve cover is arranged on the compression spring and the top passes through the mounting base plate and connects with the bottom surface of the floating wheel group. The overall structure is stable and can provide a stable rebound support force for the floating wheel group.

[0011] As a further improvement of the present invention, the detection device is a pressure sensor, and the detection trigger device is a trigger plate. The trigger plate is in an inverted L shape. The horizontal section of the trigger plate is fixedly connected to the floating wheel group, and the vertical section of the trigger plate extends downward through the mounting base plate and cooperates with the detection head of the pressure sensor. The structure has strong stability and accurate signal detection.

[0012] As a further improvement of the present invention, the horizontal section of the limit plate and the horizontal section of the trigger plate are simultaneously connected to the floating wheel set by bolts, thereby saving space and simplifying the connection.

[0013] As a further improvement of the present invention, polyurethane buffer pads are provided at the four corners of the bottom surface of the floating wheel group to prevent the floating wheel group from rigidly colliding with the mounting base plate when the floating wheel group moves to a horizontal state.

[0014] As a further improvement of the present invention, the floating wheel group includes a mounting bracket, and a guide wheel is installed on the top of the mounting bracket through the wheel axle. The guide wheel is in a frustum shape to better fit the tire surface and improve the support stability. A copper bushing is provided on the wheel axle, which has good wear resistance and is maintenance-free.

[0015] As a further improvement of the present invention, the inclination angle of the floating wheel set is 5°, and the control of the inclination angle can be achieved by adjusting the limit screw to ensure the initial contact area between the tire and the floating wheel set without affecting the entry and exit of the wheel.
