Description
Technical Field
[0001] This utility model relates to the field of multi-level parking garage technology, specifically a double-layer multi-level parking garage designed to prevent falls. Background Technology
[0002] Existing automated parking systems typically employ a platform lifting structure, using a geared motor to drive a chain to move the platform up and down. When a vehicle is parked on the upper level, the platform rises to its highest position, at which point its stability relies primarily on the self-locking function of the geared motor to prevent accidental descent. However, this design has the following safety hazards and technical defects:
[0003] 1. If the geared motor wears out, malfunctions in the circuit, or fails the self-locking mechanism due to long-term load operation, the vehicle platform may lose its support, causing the vehicle to fall from a height and resulting in a serious safety accident.
[0004] 2. The drive chain may break due to fatigue, corrosion or overload during long-term use, causing the vehicle platform to fall uncontrollably.
[0005] Therefore, there is an urgent need for a highly reliable safety protection technology for automated parking garages to solve the problem of vehicle platform falling due to mechanical failure and improve the safety and stability of parking equipment. Utility Model Content
[0006] To address the technical problems in the background art, this utility model discloses a double-layer three-dimensional parking garage that prevents falls.
[0007] This utility model provides a double-layer three-dimensional parking garage that prevents falls, including a parking rack and a car carrier plate. The car carrier plate is raised and lowered by a geared motor under the action of chain drive. The parking rack is equipped with hooks.
[0008] The upper end of the hook is hinged to the parking frame, and the lower end extends with an upward-curving hook portion, forming an upward-opening groove.
[0009] The lower end face of the hook is arranged at an angle, and its height decreases from the hook to the root.
[0010] The vehicle platform is equipped with hooks, which engage with the lifting hooks in sequence through a rising and falling motion.
[0011] The hook is also equipped with an automatic release plate;
[0012] When the hook disengages from the hook in sequence through the rising and falling motion, the disengagement plate seals the opening end of the groove and is arranged at an angle, with its height decreasing from the hook towards the hook part.
[0013] Furthermore, a connecting plate is also provided on the parking frame. The upper end of the connecting plate is hinged to the parking frame, and a weight is provided at the lower end. The weight abuts against the outer side of the hook facing away from the hook, and under its gravity, it generates a downward rotating thrust on the hook.
[0014] Furthermore, the automatic release plate extends outward with multiple rotationally symmetrical slide plates; hooks are located between adjacent slide plates; when the hooks rise to the position of disengaging from the hook, the automatic release plate is fixed by the blocking assembly, and one of the slide plates blocks the opening end of the groove; this slide plate is arranged at an angle.
[0015] Furthermore, the slides are configured as four pieces; the weight is configured as a blocking component; when the hook rises to the position of disengaging from the hook, the upper end of one of the slides abuts against the lower end of the weight; the direction of the pressure applied by the weight and the direction of extension of the slide in contact with the weight coincide.
[0016] Furthermore, both the hook and the connecting plate are hinged to the parking frame via hinge shafts.
[0017] Furthermore, the hook includes two symmetrically spaced hook plates; the upper ends of the hook plates are fixedly connected by a connecting plate; the inner sides of the lower ends of the hook plates are fixedly connected by a partition; and the hook plates are all fitted with hinge shafts.
[0018] Furthermore, the connecting plate is located between the hook plates.
[0019] Furthermore, the automatic release plate is located between the hook plates and is hinged to the middle position of the hook plates.
[0020] The beneficial effects of this utility model are:
[0021] 1. When the vehicle carrier is placed in the air-mounted parking space, the vehicle carrier is fixed by hooking the hook to avoid the risk of the vehicle carrier falling.
[0022] 2. When the hook is engaged with the lifting hook, the lifting hook bears the load of the vehicle platform and the vehicle, while the reduction motor and chain are not subjected to stress, making the reduction motor and chain less prone to damage and extending their service life.
[0023] 3. The lower end face of the hook is inclined to serve as a guide; when the hook moves upward, the hook can automatically rotate upward in the opposite direction of the hook.
[0024] 4. With the inclined design of the lower end face of the hook and the combined effect of the automatic release plate, the mechanical anti-fall structure of the hook and the hook does not require additional power to drive. It can automatically lock and unlock by relying solely on the lifting action of the vehicle platform, which reduces the system complexity and failure rate. Attached Figure Description

[0032] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0033] like Figure 1 As shown, this utility model discloses a double-layer three-dimensional parking garage that prevents falls, including a parking rack 1 and a car carrier 2. The car carrier 2 is raised and lowered by a geared motor under the action of chain drive.
[0034] The following content is based on Figure 4 For reference.
[0035] A hook 3 is installed on the parking frame 1. The upper end of the hook 3 is hinged to the parking frame 1 via a horizontally arranged hinge shaft 8, and the lower end extends to the upper right with a hook portion 31, forming an upward-opening groove 32; the lower end face of the hook portion 31 is inclined, and its height increases from left to right. To facilitate the processing of the hook 3 and reduce its weight, the specific structure of the hook 3 is as follows: Figure 2 and Figure 3 As shown, the hook 3 includes two symmetrically spaced hook plates 33; the upper end of the hook plate 33 is fixedly connected by a fixing plate 34; the inner side of the lower end of the hook plate 33 is fixedly connected by a spacer 35; and the hook plate 33 is fitted with a hinge shaft 8.
[0036] The vehicle platform 2 is equipped with hooks 4, which are U-shaped with their openings facing downwards. Hooks 4 engage with hooks 3 sequentially through a rising and falling motion. The specific operation process is as follows: Figure 4-7As shown, during the ascent of the vehicle platform 2, the hook 4 first contacts the lower end face of the hook 3 and applies pressure and thrust to the lower end face of the hook 3. Under the tilting action of the lower end face of the hook 3, the hook 3 rotates to the left; when the hook 4 moves upward to disengage from the hook 3, the hook 3 returns to its original position under the action of gravity, at which point the hook 4 is located directly above the groove 32. When the vehicle platform 2 is driven to descend, the hook 3 can stably and automatically engage within the groove 32.
[0037] Because the hook 3 is relatively light, it is prone to inaccurate and unstable repositioning due to the friction of the hinge shaft 8. Therefore, a connecting plate 6 is also installed on the hinge shaft 8. The upper end of the connecting plate 6 is hinged to the hinge shaft 8, and a weight 7 is provided at the lower end. The weight 7 is biased to the left and abuts against the left side of the hook 3. With this arrangement, when the weight 7 rotates downward under its own weight, it will generate a thrust on the hook 3, enabling the hook 3 to be repositioned stably.
[0038] The connecting plate 6 is located between the hook plates 33, and the weight 7 extends to both sides in the thickness direction of the connecting plate 6, so that the weight 7 abuts against the left side of the two hook plates 33. This arrangement can make the hook 3 bear the force evenly and the reset more stable.
[0039] To enable the hook 3 to automatically disengage from the groove 32, an automatic disengagement plate 5 is also provided between the hook plates 33. The automatic disengagement plate 5 is rotatably connected to the middle position of the hook 3; the automatic disengagement plate 5 also extends outwards with four rotationally symmetrical sliding plates 51, the extension direction of which coincides with the hinge point of the automatic disengagement plate 6. The sliding plates 51 are respectively designated as the first sliding plate 511, the second sliding plate 512, the third sliding plate 513, and the fourth sliding plate 514. When the hook 4 engages with the hook 3, the first sliding plate 511 is located above the hook 4, the second sliding plate 512 is located to the left of the first sliding plate 511, and the third sliding plate 513 is located below the hook 4.
[0040] When hook 4 needs to be detached from hook 3, such as Figure 8-11As shown, the hook 4 is first driven to rise, pushing the first slide plate 511 upward, thereby causing the automatic disengagement plate 5 to rotate. The hook 4 continues to rise until the lower end of the second slide plate 512 abuts against the lower end of the weight 7, and the direction of the pressure applied by the weight 7 to the second slide plate 512 coincides with the extension direction of the second slide plate 512. At this time, the second slide plate 512 and the weight 7 form a force balance, which can keep the position fixed. At this time, the third slide plate 513 rotates upward to block the opening end of the groove 32, and the third slide plate 513 also tilts to the lower right. Then, the hook 4 is driven to descend, and a downward pushing force is applied to the third slide plate 513. The third slide plate 513 drives the hook 3 and the automatic disengagement plate 5 to rotate to the left. When the hook 4 descends to disengage from the third slide plate 513, the direction of the pressure applied by the weight 7 to the second slide plate 512 is offset from the extension direction of the second slide plate 512. The weight 7 drives the second slide plate 512 to rotate downward and pushes the hook 3 to reset. In this way, the hook 4 automatically disengages from the hook 3.
[0041] Compared to existing technologies, the advantages of this embodiment are: 1. When the vehicle carrier 2 parks the vehicle in the air-filled loading position, the vehicle carrier 2 is fixed by hooking the hook 4 with the lifting hook 3, thereby avoiding the risk of the vehicle carrier 2 falling. 2. When the hook 4 is engaged with the lifting hook 3, the lifting hook 3 bears the load of the vehicle carrier 2 and the vehicle, while the reduction motor and chain are not under stress, making the reduction motor and chain less prone to damage and extending their service life. 3. The lower end face of the hook 31 is inclined, serving as a guide; when the hook 4 moves upward, the lifting hook 3 can automatically rotate upward in the opposite direction to the hook 31. 4. With the combined effect of the inclined lower end face of the hook 31 and the automatic disengagement plate 5, the mechanical anti-fall structure of the lifting hook 3 and hook 4 does not require additional power drive, and can achieve automatic locking and unlocking solely by the lifting action of the vehicle carrier 2, reducing system complexity and failure rate.
[0042] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
