Description

Technical Field

[0001] This utility model relates to the field of three-dimensional parking garage technology, specifically a foldable cantilever space expansion structure. Background Technology

[0002] Multi-level parking garages are highly efficient parking facilities that utilize mechanical structures to create multiple parking levels. They can significantly increase the number of parking spaces on limited land and are commonly found in urban commercial areas, residential areas, and other places with high parking demand, providing an effective solution to parking problems.

[0003] Utility model patent CN213626867U discloses a lift for an automated parking garage. This lift includes a first placement slot, a second placement slot, and a guide rod. A return spring is fixedly connected inside the first placement slot, and a support block is fixedly connected to the top of the return spring. An inclined surface with a slot is provided on the upper front of the support block. This utility model relates to the field of automated parking garage technology. Through the coordinated use of the first and second placement slots, guide rod, return spring, support block, inclined surface, slot, support spring, and stop block, when a vehicle drives onto the lifting platform, the return spring causes the support block to rise, thus locking the wheels and preventing the vehicle from rolling away. This solves the problem that existing automated parking garage lifts lack a component for limiting and fixing vehicles, leading to vehicle roll-away when the lift malfunctions, causing losses to the owner.

[0004] The lift used in this multi-level parking garage cannot expand the space around the lift platform after parking. When a vehicle is parked, the small distance between the parking area and the surrounding structure makes it difficult for people to get out of the car smoothly due to limited space. This is especially true in multi-car garages, where it can obstruct the opening of car doors and affect the user experience. In view of this, we propose a foldable cantilever space expansion structure. Utility Model Content

[0005] The purpose of this utility model is to provide a foldable cantilever space expansion structure to solve the problem mentioned in the background art of inconvenience for people to get out of the car due to limited space after parking.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A foldable cantilevered space expansion structure includes a parking platform. A pair of lifting seats are provided at both ends of the parking platform, which are used to lift the parking platform. Space expansion mechanisms are installed on both ends of the parking platform, allowing for horizontal lateral extension and retraction on the parking platform. Each space expansion mechanism includes a cantilever plate extending into and slidably connected to the parking platform, and a power component installed within the parking platform. The power component drives the cantilever plate to move. The power component includes a rotating motor and a long shaft. The rotating motor is coaxially connected to the long shaft, which is rotatably connected to the parking platform. Several friction wheels are coaxially fixed on the long shaft, serving as the power source for the cantilever plate to move within the parking platform.

[0008] Preferably, side grooves are provided at the bottom edges of both ends of the parking plate, and a storage groove is provided between the groove walls of the two side grooves, into which the cantilever plate is stored;

[0009] In this setup, the side grooves and storage slots provide storage space for the cantilever panel, keeping the structure compact when not in use.

[0010] Preferably, side grooves are provided at the left and right edges of the top surface of the parking plate, and the side grooves are connected to the side grooves. A protruding edge is provided at the outer edge of the top surface of the cantilever plate. When the cantilever plate retracts into the parking plate along the storage groove, the protruding edge will eventually abut against the groove wall of the side groove.

[0011] In this configuration, the side groove and the convex edge work together to form a limiting structure, ensuring that the cantilever plate is accurately positioned after it retracts into place.

[0012] Preferably, a guardrail is fixed to the top of the protruding edge, and the guardrail moves synchronously with the movement of the cantilever plate;

[0013] In this setup, the guardrail moves synchronously with the cantilever panel, providing safety protection for personnel after the space expands.

[0014] Preferably, a plurality of movable wheels are installed at the outer end of the bottom surface of the cantilever plate. When the cantilever plate moves in the parking plate, the movable wheels are used to reduce the moving resistance of the cantilever plate.

[0015] In this setting, the movable wheels reduce friction when the cantilever plate moves, making the extension and retraction process smoother.

[0016] Preferably, a limiting groove is provided at both the front and rear edges of the cantilever plate, the inner end of the limiting groove is closed and the outer end of the limiting groove is open, and a limiting block is installed on both the front and rear groove walls of the side groove, the limiting block extending into the limiting groove;

[0017] In this configuration, the limiting groove and the limiting block work together to prevent the cantilever plate from extending excessively when it moves outward, thus ensuring the safety of the structure during operation.

[0018] Preferably, the long shaft passes through the side groove, the friction wheel is located in the side groove, a groove is formed on the outer peripheral surface of the friction wheel, a rubber wheel ring is fitted in the groove, and the outer ring of the rubber wheel ring abuts against the bottom surface of the cantilever plate;

[0019] In this configuration, the wheel groove and rubber rim increase the friction between the friction wheel and the bottom surface of the cantilever plate, making power transmission more stable.

[0020] Preferably, a plurality of fixed seats are sleeved on the outer side of the long shaft, and the ends of the fixed seats are fixed to the groove wall of the side groove, and the long shaft can rotate in the fixed seats;

[0021] In this configuration, the fixed base supports the long shaft, ensuring its stability during rotation.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] This foldable cantilevered space expansion structure features horizontally retractable space expansion mechanisms on both sides of the parking platform. After the vehicle is parked, the cantilever platform can extend from the storage slot, expanding the usable space around the parking platform and providing more space for people to get out of the car, thus improving the ease of use of the multi-level parking equipment.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0035] Please see Figures 1-7 The foldable cantilevered space expansion structure includes a parking platform 100. A pair of lifting seats 110 are provided at both ends of the parking platform 100. The lifting seats 110 are used to raise and lower the parking platform 100, allowing it to meet different parking height requirements. Space expansion mechanisms 200 are installed on both ends of the parking platform 100. The space expansion mechanisms 200 can perform horizontal lateral extension and retraction on the parking platform 100. The space expansion mechanism 200 includes a cantilever plate 210 that extends into and slidably connects to the parking platform 100, and a power component 220 installed in the parking platform 100. The power component 220 drives the cantilever plate 210. The space expansion mechanism 200 allows the cantilever plate 210 to perform horizontal lateral extension and retraction under the drive of the power component 220, thereby expanding the space around the parking platform.

[0036] like Figures 3-5As shown, in this utility model, side grooves 120 are provided at the bottom edges of both ends of the parking plate 100, and a storage groove 140 is provided between the groove walls of the two side grooves 120. The cantilever plate 210 is stored in the storage groove 140. The side grooves 120 and the storage groove 140 provide storage space for the cantilever plate 210, so that the structure can remain compact when not in use. Side grooves 130 are provided at the left and right edges of the top surface of the parking plate 100. The side grooves 130 are connected to the side grooves 120. A protruding edge 211 is provided at the outer edge of the top surface of the cantilever plate 210. When the cantilever plate 210 retracts into the parking plate 100 along the storage groove 140, the protruding edge 211 will eventually abut against the groove wall of the side groove 130. The cooperation between the side groove 130 and the protruding edge 211 can play a limiting role when the cantilever plate 210 retracts into place, ensuring that its storage position is accurate. Limiting grooves 214 are provided on both the front and rear edges of the cantilever plate 210. The inner end of the limiting groove 214 is closed and the outer end is open. Limiting blocks 121 are installed on both the front and rear walls of the side groove 120. The limiting blocks 121 extend into the limiting groove 214. When the cantilever plate 210 moves outward along the receiving groove 140, the limiting blocks 121 will eventually abut against the inner wall of the limiting groove 214. The setting of the limiting grooves 214 and the limiting blocks 121 can limit the cantilever plate 210 when it moves outward, prevent it from extending too far, and ensure the safety of the structure during operation.

[0037] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, specifically, a guardrail 212 is fixed to the top of the protruding edge 211. The guardrail 212 moves synchronously with the movement of the cantilever plate 210. The guardrail 212 provides protection after the cantilever plate 210 extends into the extended space, ensuring personnel safety. Several moving wheels 213 are installed at the outer end of the bottom surface of the cantilever plate 210. When the cantilever plate 210 moves in the parking platform 100, the moving wheels 213 reduce the moving resistance of the cantilever plate 210, making the extension and retraction of the cantilever plate 210 smoother.

[0038] like Figure 4 , Figure 6 and Figure 7As shown, the power assembly 220 further includes a rotary motor 221 and a long shaft 222. The rotary motor 221 is coaxially connected to the long shaft 222, and the long shaft 222 is rotatably connected to the parking plate 100. Several friction wheels 223 are coaxially fixed on the long shaft 222. The friction wheels 223 are the power components for the movement of the cantilever plate 210 in the parking plate 100. By starting the rotary motor 221, the rotary motor 221 can drive the friction wheels 223 to rotate through the long shaft 222, providing power for the movement of the cantilever plate 210. The long shaft 222 passes through the side groove 120, and the friction wheel 223 is located inside the side groove 120. A wheel groove 2231 is opened on the outer peripheral surface of the friction wheel 223, and a rubber wheel ring 2232 is fitted in the wheel groove 2231. The outer ring of the rubber wheel ring 2232 abuts against the bottom surface of the cantilever plate 210. The wheel groove 2231 and the rubber wheel ring 2232 can increase the friction between the friction wheel 223 and the bottom surface of the cantilever plate 210, making the power transmission more stable and reliable.

[0039] like Figure 4 and Figure 6 As shown, in addition, as shown in the figure, a number of fixed seats 224 are sleeved on the outer side of the long shaft 222. The ends of the fixed seats 224 are fixed on the groove wall of the side groove 120. The long shaft 222 can rotate in the fixed seats 224. The fixed seats 224 are used to support the long shaft 222, prevent the long shaft 222 from bending under force, and ensure the stability of the long shaft 222 when rotating.

[0040] It is worth noting that the rotating motor 221 involved in this utility model is a conventional technology and will not be described in detail here.

[0041] In this embodiment, the foldable cantilever space expansion structure is used as follows: First, the parking platform 100 is adjusted to the ground via the lifting seat 110 for vehicle parking. Then, the rotating motor 221 is started, causing the rotating motor 221 to drive the friction wheel 223 to rotate via the long shaft 222. The rubber wheel rim 2232 on the friction wheel 223 abuts against the bottom surface of the cantilever plate 210, thereby causing the cantilever plate 210 to move outward along the storage groove 140, expanding the space around the parking platform. Next, the vehicle is parked on the parking platform 100, and people can easily get out of the vehicle through the expanded space. Finally, after the people get out of the vehicle, the rotating motor 221 is started again, causing the cantilever plate 210 to retract into the parking platform 100 along the storage groove 140, with the protruding edge 211 abutting against the groove wall of the side groove 130, completing the storage of the cantilever plate 210.
