Description

Technical Field

[0001] The present invention relates to the technical field of three-dimensional parking devices, and more specifically, to a front wheel in-place device for a mechanical three-dimensional parking garage and a limit device for the parking garage. Background Art

[0002] The comb-tooth type is a handling form of three-dimensional garage products. The structure is divided into a lifting channel and berths. The lifting channel is provided with a lifting comb-tooth frame and a lifting system. The lifting comb teeth are divided into two parts: front-wheel comb teeth and rear-wheel comb teeth. The berths are transverse comb-tooth frames distributed on both sides of the lifting channel. The entrance and exit are arranged in the lifting channel on the ground floor or are provided with a fixed rotary disk. When parking a vehicle, through the exchange between the lifting comb-tooth frame and the transverse comb-tooth frame, it reaches the designated floor, and through the transverse movement of the transverse comb-tooth frame, the handling from the channel to the berth is realized. Through the transverse rotary disk, the vehicle is turned around and enters and exits the garage forward.

[0003] Existing mechanical three-dimensional parking garages generally store and retrieve vehicles according to the following method or the opposite method: First, the vehicle is parked in the entrance and exit room, then the vehicle is carried by a transporter to a lifting or transverse movement device, and then the vehicle is transported to the parking floor where the target parking space is located by the lifting or transverse movement device. Finally, the vehicle is parked in the parking space by the transporter.

[0004] When a customer parks a vehicle, if the vehicle is not parked exactly in the center of the comb-tooth platform and is biased or tilted left and right, it will cause difficulties for the lifting system to complete its work tasks and may even cause accidents in severe cases.

[0005] Customers can only adjust the position of the vehicle by observing the position of the vehicle with their eyes, which requires a relatively high level of reversing and parking skills for customers, and thus the satisfaction of customers using the three-dimensional parking garage is affected. The possible dangerous situations are: 1. The lifting system starts working before the front wheels of the vehicle reach the front-wheel comb teeth position of the lifting comb teeth; 2. The lifting system starts working when only a part of the front wheels of the vehicle reach the front-wheel comb teeth or only one front wheel reaches the front-wheel comb teeth; 3. The vehicle stops or is parked obliquely above the lifting comb teeth. When the parking personnel do not notice the above situations and the lifting system starts working, it may cause damage to the vehicle or personnel.

[0006] Therefore, how to quickly and accurately park the vehicle on the comb-tooth frame, predict and sense the in-place of the wheels, and improve the structure of the mechanical three-dimensional parking garage to better meet the market demand has great practical significance. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to provide a front wheel positioning device for a mechanical three-dimensional parking garage in view of the above deficiencies. This device cooperates with the original comb structure of the three-dimensional parking garage according to the actual parking and parking needs. The provided front wheel positioning device can accurately and quickly help the driver find the accurate position where the wheels need to be parked. In order to ensure that the vehicle is parked in a safe position on the lifting comb frame, an additional protection for automatically detecting whether the vehicle position meets the requirements is added, improving the safety and efficiency of vehicle access and adding a safety protection system for the intelligent mechanical parking equipment to be unattended.

[0008] The object of the present invention is achieved by the following technical solutions:

[0009] The provided front wheel positioning device for a mechanical three-dimensional parking garage includes a first basic comb with a front wheel positioning device inside, and a second basic comb adjacent to the first basic comb with an inclined surface structure on its upper surface; the distance between the first basic comb and the second basic comb is less than 1 / 3 of the wheel diameter;

[0010] The first basic comb includes a basic comb frame and a limiting comb frame. At the top of the limiting comb frame, there is a front wheel positioning support plate, and a flap is movably connected to the edge of the front wheel positioning support plate;

[0011] Extending downward from the upper surface of the front wheel positioning support plate and passing through the inside of the front wheel positioning support plate, an adjusting structure is installed. The adjusting structure includes a pressure rod structure, a compression spring, and a spring backing plate; at the top of the pressure rod structure, a bearing structure is installed. The outer wall of the pressure rod structure is provided with a compression spring. One end of the compression spring abuts against the bearing structure, and the other end abuts against the spring backing plate;

[0012] Outside the adjusting structure, a guide sleeve with a stop step on its inner wall is provided. The spring backing plate is sleeved in the stop step and sleeved on the outer wall of the pressure rod structure;

[0013] At the end of the pressure rod structure, a travel switch pressure plate is fixed; it is used to control the opening and closing of the travel switch.

[0014] The front wheel positioning device for this mechanical three-dimensional parking garage provides a positioning structure for the wheels (especially the front wheels of the vehicle). When the wheels reach the positions of the first basic comb and the second basic comb, the adjusting structure in the first basic comb is triggered to drive the pressure rod structure to control the opening or closing of the travel switch connected to one end of the pressure rod structure.

[0015] Further, the front wheel positioning support plate is a ramp support plate with an angle of 5° - 30° between its upper surface and the horizontal plane, and the lower surface of the front wheel positioning support plate is parallel to the bottom plate.

[0016] Further, the flap is installed at the edge of the highest end of the ramp support plate through a rotating shaft. A positioning block is provided on the inner surface of the flap, and a groove structure adapted to the positioning block is provided on the ramp support plate.

[0017] Further, the bearing structure is a deep groove ball bearing. The bearing structure is sleeved on a shaft rod installed at the top end of the pressure rod structure.

[0018] Further, a connecting ear is provided on the outer wall of the guide sleeve. The guide sleeve is fixedly connected to a mounting plate arranged in parallel with the lower surface of the front wheel in-place device through the connecting ear.

[0019] Further, both the first basic comb tooth and the second basic comb tooth include a bottom plate longitudinally installed with at least two column structures. A cross beam structure is connected to the top end of the column structure, so that the first comb tooth structure is a hollow rectangular structure.

[0020] Further, the height of the column is greater than the height of the adjusting structure.

[0021] The purpose of the present invention also lies in providing a parking garage limit device, including a front wheel comb tooth structure and a rear wheel comb tooth structure. The front wheel comb tooth structure includes the above-mentioned front wheel in-place device for a mechanical stereo parking garage.

[0022] The front wheel in-place device for a mechanical stereo parking garage of the present invention is installed in the lifting comb tooth pit at the entrance and exit of the garage. When the front wheel of the vehicle presses on the flap of the front wheel in-place device, the flap rotates downward through a movable connection structure (such as a hinge) to fit the inclined surface structure of the front wheel in-place support plate, and at the same time forces the pressure rod structure to move downward through the guide sleeve. A travel switch pressing plate is installed on the pressure rod structure, and the travel switch pressing plate contacts the limit switch contact. When the travel switch pressing plate moves downward, it triggers the limit switch to act, indicating that the front wheel has reached the position. When the front wheel of the vehicle leaves the flap, the compression spring restores, pushes up the flap, and the pressure rod structure moves upward, so as to restore the limit switch contact, indicating that the front wheel has left.

[0023] The present invention has the following beneficial effects compared with the prior art:

[0024] The purpose of the front wheel in-place device for a mechanical stereo parking garage of the present invention is to ensure that the vehicle is parked in a safe position on the lifting comb tooth frame, adding an automatic detection of whether the vehicle position meets the requirements for protection, improving the safety and efficiency of vehicle access and storage, and adding a safety protection system for the intelligent mechanical parking equipment for unattended operation. It is convenient for the vehicle to enter and exit the garage.

[0025] When the vehicle is parked, it drives into the lifting channel. Only when both front wheels on both sides press on the tipping plate can the two safety protection switches (travel switches) be triggered to act. These two safety protection switches are connected in series in the safety circuit of the PLC control system of the mechanical parking equipment, indicating that the front and rear and left and right positions of the vehicle meet the parking requirements, and then the lifting comb can perform the lifting action. This avoids dangerous situations such as the front wheels not being parked in place or the vehicle (a vehicle with a narrow wheelbase) being parked sideways and only pressing on one side of the lifting comb.

[0026] On the one hand, the parking garage limit device of the present invention improves the comfort of the driver entering and leaving the garage, facilitates vehicle storage and retrieval. On the other hand, it limits the position of the vehicle on the lifting comb, adds an automatic vehicle position protection device, prevents vehicle damage events caused by the vehicle not being parked in place or parked sideways, etc., and improves the safety and efficiency of vehicle storage and retrieval.

DETAILED DESCRIPTION OF THE INVENTION

[0033] The following specific embodiments further illustrate the present invention in detail. Unless otherwise specified, various raw materials used in the embodiments of the present invention can be obtained through regular commercial purchases or prepared according to conventional methods in the art, and the equipment used is commonly used in experiments. Unless otherwise defined or explained, all professional and scientific terms used herein have the same meaning as those familiar to skilled personnel in the art.

[0034] Embodiment 1

[0035] As Figures 1 to 5 shown, the front-wheel in-place device for this mechanical three-dimensional parking garage includes a basic comb tooth 1 with a front-wheel in-place device inside, and a basic comb tooth 2 adjacent to the basic comb tooth 1 with an inclined surface structure on its upper surface; the distance between the basic comb tooth 1 and the basic comb tooth 2 is less than 1 / 3 of the wheel diameter;

[0036] The basic comb tooth 1 includes a basic comb tooth frame and a limit comb tooth frame. The basic comb tooth frame includes a bottom plate 11 and at least two column structures 14 longitudinally installed along the bottom plate 11. The height of the column structure 14 is greater than the height of the adjustment structure. In this embodiment, two column structures 14 are provided and are respectively arranged on both sides of the bottom plate 11; and the top ends of the column structures 11 are connected with a cross beam structure 15, so that the comb tooth structure and the bottom plate 11 form a rectangular hollow structure; the cross beam structure 15 is a rectangular structure, and multiple comb tooth structures form plane comb teeth with the same interval. The top end of the limit comb tooth frame is provided with a front-wheel in-place support plate 124, and a flap 121 is movably connected to the edge of the front-wheel in-place support plate 124; the front-wheel in-place support plate 124 is a slope support plate with an included angle of 5° to 30° between its upper surface and the horizontal plane, and the lower surface of the front-wheel in-place support plate 124 is arranged parallel to the bottom plate 11. More specifically, the flap 121 is installed at the edge of the highest end of the slope support plate through a rotating shaft 123, and a positioning block 122 is arranged on the inner surface of the flap 121, and the positioning block 122 is adapted to the groove structure on the slope support plate.

[0037] An adjustment structure is installed by extending downward from the upper surface of the front-wheel in-place support plate 124 through the inside of the front-wheel in-place support plate 124. The adjustment structure includes a pressure rod structure 18, a compression spring 191 and a spring backing plate 192; a bearing structure 17 is installed at the top end of the pressure rod structure 18, a compression spring 191 is arranged on the outer wall of the pressure rod structure 18, one end of the compression spring 191 abuts against the bearing structure 17, and the other end abuts against the spring backing plate 192; a guide sleeve 19 is arranged outside the adjustment structure, a stop step is arranged on the inner wall of the guide sleeve 19, and a spring backing plate 192 sleeved on the outer wall of the pressure rod structure 18 is arranged in the stop step.

[0038] In this embodiment, the upper surface of the adjacent basic comb tooth two of the basic comb tooth one is an inclined surface structure 16. When the wheel is in place, the front wheel in-place device of the basic comb tooth one and the upper surface of the basic comb tooth two form a V-shaped positioning groove structure. The setting of this structure is beneficial to positioning the front wheel between the front wheel in-place devices, and can accurately and quickly enable the driver to find the accurate position where the wheel needs to be parked.

[0039] More specifically, a connecting ear is provided on the outer wall of the guide sleeve 19, and the guide sleeve 19 is fixedly connected to the mounting plate 102 arranged parallel to the lower surface of the front wheel in-place device through the connecting ear.

[0040] A travel switch pressing plate 101 is fixed at the end of the pressing rod structure; one end of the travel switch pressing plate 101 extends above one side of the limit switch 10, and is used to control the opening and closing of the travel switch.

[0041] As a preferred solution of this embodiment, the bearing structure 17 is a deep groove ball bearing, and the bearing structure 17 is sleeved on a shaft rod (not shown) installed at the top of the pressing rod structure 18.

[0042] The front wheel in-place device for this mechanical three-dimensional parking garage is used in cooperation with the existing lifting comb tooth frame.

[0043] In this embodiment, the front wheel in-place device for this mechanical three-dimensional parking garage is provided with a limit comb tooth frame on the basic comb tooth one. When the vehicle parks, the lifting comb tooth frame descends, and the vehicle drives into the lifting channel. Only when both front wheels on both sides press the flap, can the two safety protection switches be triggered to act. These two safety protection switches are connected in series in the safety circuit of the PLC control system of the mechanical parking equipment, indicating that the front and rear and left and right positions of the vehicle meet the parking requirements, and then the lifting comb tooth can be lifted. This avoids the dangerous situation where the front wheel is not parked in place, or the vehicle (a vehicle with a narrow wheelbase) parks sideways and only presses one side of the lifting comb tooth.

[0044] The parking garage limit device made of the front wheel in-place device for the mechanical three-dimensional parking garage of the present invention is installed in the lifting comb tooth pit at the entrance and exit of the garage. When the front wheel of the car presses the flap of the front wheel in-place device, the flap rotates downward through a movable connection structure (such as a hinge) to fit the inclined surface structure of the front wheel in-place support plate, and at the same time forces the pressing rod structure to move downward through the guide sleeve. A travel switch pressing plate is installed on the pressing rod structure, and the travel switch pressing plate contacts the contact of the limit switch. When the travel switch pressing plate moves downward, it triggers the limit switch to act, indicating that the front wheel has reached the position. When the front wheel of the car leaves the flap, the compression spring restores, pushes the flap up, and the pressing rod structure moves upward, so as to realize the restoration of the limit switch contact, indicating that the front wheel has left.
