Description

Technical Field

[0001] This application relates to the field of parking technology, and in particular to a rotating lifting parking tray. Background Technology

[0002] As the core load-bearing component of automated parking systems, the anti-slip performance of the rotating lifting parking pallet directly affects the safety and stability of the parking process. This is especially true in scenarios where it is adapted to the narrow tires of small new energy vehicles with a width of ≤185mm, where the need for anti-slip is even more urgent.

[0003] Existing rotating and lifting parking trays mostly employ traditional anti-slip designs, primarily consisting of flat rubber anti-slip strips, straight grooved anti-slip plates, or evenly distributed cylindrical protrusions. Their design focuses on the basic anti-slip requirements of general-purpose vehicles, failing to specifically optimize for the structural characteristics and stress properties of narrow tires. This results in numerous technical shortcomings in practical applications. The anti-skid structure is poorly adapted to narrow tires; the grip enhancement mechanism is simplistic, relying solely on the basic friction of the rubber material and lacking auxiliary grip structures; and it lacks a multi-dimensional anti-skid mechanism.

[0004] Therefore, a rotating lifting parking pallet is proposed. Summary of the Invention

[0005] This application aims to at least partially solve one of the technical problems in the aforementioned technologies.

[0006] To achieve the above objectives, the first aspect of this application proposes a rotary lifting parking pallet, comprising two support members and several pallet bodies, wherein an active rotating shaft is installed between the support members, and active lifting gears are installed at both ends of the active rotating shaft near the support members. An auxiliary rotating shaft is installed between the support members. The auxiliary rotating shaft is located below the active rotating shaft. Auxiliary lifting gears are installed at both ends of the auxiliary rotating shaft near the support members. A transmission sprocket is installed between the active lifting gear and the auxiliary lifting gear; The transmission sprocket is movably connected to the transverse plate via a movable component, and the transverse plate is movably connected to the pallet body via a connecting plate; The surface of the tray body is provided with a trapezoidal groove corresponding to a car tire. The trapezoidal groove is narrow at the front and wide at the back and has an inclined surface inside. The inclined surface has a vacuum adsorption microcavity. The inner wall of the trapezoidal groove is provided with a composite anti-slip layer.

[0007] In addition, the rotary lifting parking pallet proposed in this application may also have the following additional technical features: As a further description of the above technical solution: A drive component is installed at one end of the active rotating shaft.

[0008] As a further description of the above technical solution: The driving component includes a motor and a reducer. The output end of the motor is connected to the input end of the reducer, and the output end of the reducer is connected to the drive shaft.

[0009] As a further description of the above technical solution: The movable component includes a connecting lug and a connecting rod. The connecting lug is fixed to the transmission sprocket, and the connecting rod is inserted into the through hole of the connecting lug. The connecting rod passes through the transverse plate and is interference-fitted with it.

[0010] As a further description of the above technical solution: One end of the connecting plate is connected to the side of the transverse plate by a pin, and the other end is connected to the side of the pallet body by a pin.

[0011] As a further description of the above technical solution: The trapezoidal groove has an internal slope that slopes downwards at an angle of 20-30 degrees.

[0012] As a further description of the above technical solution: The vacuum adsorption microcavity has a diameter of 1.5 cm and a depth of 0.5 cm.

[0013] As a further description of the above technical solution: The composite anti-slip layer is made of nitrile rubber and a 15% steel wire skeleton.

[0014] Advantages of this invention: The rotary lifting parking pallet of this application solves the problem of narrow tire structure characteristics. Through structural optimization, material improvement and multi-dimensional grip synergistic design of anti-slip solution, it solves the technical problems of high slip rate, short service life, severe tire wear and poor environmental adaptability in the prior art. Featuring a trapezoidal groove design, specifically designed for narrow tires, it utilizes an angled surface to contact the tire, increasing the contact area by 35% compared to traditional anti-skid strips; A composite material system is used to balance rigidity and wear resistance, thereby improving service life; It is suitable for use throughout the entire life cycle of tires. Even if the tread wears down, the vacuum suction force can still compensate for insufficient gripping force and maintain stability.

[0016] The above and / or additional aspects and advantages of this application will become apparent and readily understood from the following description of the embodiments taken in conjunction with the accompanying drawings, wherein: Figure 1 This is a front structural diagram of the present invention; Figure 2 This is a schematic diagram of the rear structure of the present invention; Figure 3 This is a schematic diagram of the parking tray structure of the present invention. Detailed Implementation

[0017] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0018] The rotating lifting parking pallet of Embodiment 1 of this application will be described below with reference to the accompanying drawings.

[0019] like Figure 1-2 As shown, the rotary lifting parking pallet of Embodiment 1 of this application may include two support members 1 and several pallet bodies 5. An active rotating shaft 7 is installed between the support members 1, and active lifting gears 10 are installed at both ends of the active rotating shaft 7 near the support members 1 for active rotation, facilitating subsequent lifting. To achieve automatic rotation, a drive member 8 is installed at one end of the active rotating shaft 7. The drive member 8 includes a motor and a reducer. The output end of the motor is connected to the input end of the reducer, and the output end of the reducer is connected to the active rotating shaft 7. The motor and its associated components drive the active rotating shaft 7 to rotate. An auxiliary rotating shaft 9 is installed between the support members 1, positioned below the active rotating shaft 7 to facilitate cooperation between the two shafts. Auxiliary lifting gears 12 are installed at both ends of the auxiliary rotating shaft 9 near the support members 1 for auxiliary rotation, facilitating subsequent lifting. Simultaneously, the active lifting gears 10 and auxiliary lifting gears 12 are connected at their respective ends. A transmission sprocket 11 is installed between the lowering gears 12. When the active lifting gear 10 rotates, it can drive the auxiliary lifting gear 12 to rotate, forming a lifting system. The rotation of the gears drives the pallet body 5 to rotate and lift. In order to connect the pallet body 5 and prevent it from tipping over due to not being perpendicular to the ground during the lifting process, the moving parts include a connecting ear 6 and a connecting rod 2. The connecting ear 6 is fixed to the transmission sprocket 11, and the connecting rod 2 is inserted into the through hole of the connecting ear 6. The connecting rod 2 passes through the transverse plate 3 and is interference-fitted with it, so that the parking pallet 5 is connected to the connecting ear 6. One end of the connecting plate 4 is connected to the side of the transverse plate 3 by a pin, and the other end is connected to the side of the pallet body 5 by a pin, so that the pallet body 5 can rotate relative to the transmission sprocket 11. Through the rotation design, the parking pallet 5 is always perpendicular to the ground to prevent the car from falling off.

[0020] like Figure 2As shown, to enhance the fixation of the car tire and maintain stability within the tray, preventing accidents during lifting and lowering, a trapezoidal groove 13 corresponding to the car tire is formed on the surface of the tray body 5. The trapezoidal groove 13 is designed to be narrower at the front and wider at the back, with an internal sloping surface. A vacuum adsorption micro-cavity 14 is formed on the sloping surface. When the car tire enters the trapezoidal groove 13, the vacuum adsorption micro-cavity 14 adsorbs the tire (the air inside the cavity is expelled when the tire rolls over it, creating negative pressure and improving adhesion), thus enhancing stability. Simultaneously, a composite anti-slip layer is formed on the inner wall of the trapezoidal groove 13 to improve surface wear resistance and the coefficient of friction. The internal sloping surface of the trapezoidal groove 13 is inclined downwards at an angle of 20-30 degrees, causing the car tire to sink below the surface of the tray, preventing lateral swaying and maintaining stability. The vacuum adsorption micro-cavity 14 has a diameter of 1.5 cm and a depth of 0.5 cm, utilizing the principle of vacuum adsorption to enhance adhesion and further improve tire stability. The composite anti-slip layer is made of a combination of nitrile rubber and a 15% steel wire skeleton, mixed with 5%... Ceramic particles (0.3-0.5mm in diameter) improve surface wear resistance and coefficient of friction, preventing tire slippage and accidents.

[0021] Operating principle: When the car is parked in the tray body 5, the four tires enter the trapezoidal grooves 13 on the tray. Due to the existence of the slope, the bottom of the tire will be lower than the surface of the tray after entering, forming a sinking. At the same time, there are vacuum adsorption microcavities 14 on the slope. When the tire rolls over, the air in the cavity is expelled to form negative pressure, which further improves the stability of the tire in the trapezoidal grooves 13. In addition, the presence of composite anti-slip can prevent the tire from slipping and has good wear resistance, which can be used for a long time. During lifting, the motor and reducer drive the drive shaft 7 to rotate, thereby driving the drive lifting gear 10 to rotate. Through the transmission sprocket 11, the auxiliary lifting gear 12 below rotates, forming a rotating state. Since the pallet body 5 is connected to the transmission sprocket 11 (see the above embodiment for details), the transmission sprocket 11 drives the pallet body 5 to lift and lower, thereby adjusting the height for convenient use and parking.
