Description

Technical Field

[0001] This utility model belongs to the field of mechanical parking space technology, specifically relating to a mechanical parking space with a weight limiting function. Background Technology

[0002] With the rapid pace of urbanization, the number of vehicles in cities has increased dramatically, making parking difficulties increasingly prominent. To address this issue, double-layer mechanical parking spaces have emerged. Existing double-layer mechanical parking spaces typically consist of multiple parking platforms. After a user parks their vehicle in a designated area, a mechanical lifting and translating device automatically moves the vehicle to the designated parking spot. However, this design has several drawbacks. First, due to the weight of the vehicle itself, the back-and-forth movement of the lifting and translating devices results in high energy consumption, increasing operating costs and environmental impact. Second, the complex mechanical structure leads to difficulties in later maintenance, increasing maintenance costs and time. Furthermore, the complex structure of the lifting and translating devices in traditional designs requires high manufacturing and installation costs. To solve these problems, this invention proposes a semi-embedded double-layer mechanical parking space with a weight-limiting function. This achieves double-layer parking while simplifying the mechanical structure, reducing energy consumption, decreasing the complexity and cost of later maintenance, and maintaining high parking efficiency.

[0003] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a mechanical parking space with a weight limiting function, comprising a frame, with lifting channels on both sides of the frame, a parking space frame slidably connected to the frame inside the lifting channels, a car frame at the top and bottom of the parking space frame, a platform at the bottom of each car frame, a weight limiting mechanism at the bottom of the platform, a guide wheel at the top of the frame, a traction machine at the top of the frame, multiple steel wire ropes on the traction wheel of the traction machine, both ends of the steel wire ropes being fixed to the top of the two parking space frames respectively, and the rope body being mounted on the guide wheel, and a fixing mechanism on both sides of the parking space frame.

[0005] As a preferred technical solution of this utility model, the frame is a rectangular frame structure, and the overall height of the parking space frame is equal to 2 / 3 of the internal height of the frame.

[0006] As a preferred technical solution of this utility model, the fixing mechanism includes a fixing hole, a limiting rail and a drive motor. The fixing hole is opened in the side wall of the frame, the limiting rail is fixed to the side wall of the parking space frame, and a support rod is slidably connected inside the limiting rail. The output end of the drive motor and the support rod body are connected by a gear and rack transmission.

[0007] As a preferred embodiment of this utility model, the weight limiting mechanism includes a pressure sensor, a controller, and an alarm. The pressure sensor is installed at the four corners of the bottom of the table, and the controller is electrically connected to the alarm, the pressure sensor, and the driver of the drive motor, respectively.

[0008] As a preferred embodiment of this utility model, guide rails are installed at the four corners of the lifting channel, and pulleys are fixed at the four corners of the parking space frame. The lifting channel and the parking space frame are slidably connected by the guide rails and pulleys.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] (1) This utility model adopts a lifting mechanism driven by the vehicle's own weight and a traction motor, utilizing the vehicle's gravitational potential energy conversion to achieve low-power operation. Compared with traditional all-mechanical power drive, energy consumption is reduced by more than 30%, significantly reducing operating costs. Replacing the complex lifting mechanism with a traction system, combined with a semi-embedded rectangular frame design, reduces the number of mechanical parts by 30% to 40%, lowering manufacturing costs and installation difficulty. It is also easy to maintain, with a lower failure rate, resulting in lower maintenance costs in the later stages.

[0011] (2) Multiple steel wire ropes are used for connection to improve durability and installability, and avoid the risk of falling due to the breakage of a single rope; the fixing mechanism drives the support rod to insert into the fixing hole through gear and rack transmission, so that the displacement deviation of the parking space frame after locking is less than 1mm, ensuring that the vehicle is parked stably. Pressure sensors are integrated at the four corners of the platform to monitor the vehicle weight in real time and link the alarm system through the controller, effectively avoiding structural damage or safety hazards caused by overload, and improving the service life of the equipment and parking safety.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0017] Example

[0018] Please see Figure 1-2 This utility model provides the following technical solution: a mechanical parking space with weight limiting function, including a frame 1, with lifting channels 2 on both sides of the frame 1, and a parking space frame 3 slidably connected to the frame 1 inside the lifting channels 2. Car frames 4 are provided at the top and bottom of the parking space frame 3, and a platform 5 is installed at the bottom of each car frame 4. A weight limiting mechanism is installed at the bottom of the platform 5. A guide wheel 6 is installed at the top of the frame 1, and a traction machine 7 is installed at the top of the frame 1. Multiple steel wire ropes 8 are installed on the traction wheels of the traction machine 7. The two ends of the steel wire ropes 8 are respectively fixed to the top of the two parking space frames 3, and the rope body of the steel wire rope 8 is installed on the guide wheel 6. A fixing mechanism is provided on both sides of the parking space frame 3. The frame 1 is a rectangular frame structure, and the overall height of the parking space frame 3 is equal to 2 / 3 of the internal height of the frame 1. In this embodiment, the car's own weight and the traction motor jointly drive the lifting, utilizing gravitational potential energy conversion to achieve low power consumption. Energy consumption is lower than traditional methods, reducing operating costs. Traction systems replace complex lifting mechanisms, reducing mechanical parts by 30% to 40% and lowering manufacturing and installation costs. They are easy to maintain, have a low failure rate, and save on later maintenance costs.

[0019] To ensure the stability of the parking frame 3 when it is fixed, in this embodiment, as a preferred technical solution of the present invention, the fixing mechanism includes a fixing hole 12, a limiting rail 13 and a drive motor 14. The fixing hole 12 is opened on the side wall of the frame 1, the limiting rail 13 is fixed to the side wall of the parking frame 3, and a support rod 15 is slidably connected inside the limiting rail 13. The output end of the drive motor 14 and the body of the support rod 15 are connected by a gear and rack transmission.

[0020] To avoid excessive vehicle weight leading to a large difference in distance between the two vehicles, in this embodiment, as a preferred technical solution of the present invention, the weight limiting mechanism includes a pressure sensor 9, a controller 10, and an alarm 11. The pressure sensor 9 is installed at the four corners of the bottom of the platform 5, and the controller 10 is electrically connected to the alarm 11, the pressure sensor 9, and the driver of the drive motor 14, respectively.

[0021] To ensure the stability of the parking space frame 3 during lifting, in this embodiment, as a preferred technical solution of the present invention, guide rails 16 are installed at the four corners of the lifting channel 2, and pulleys are fixed at the four corners of the parking space frame 3. The lifting channel 2 and the parking space frame 3 are slidably connected through the guide rails 16 and pulleys.

[0022] Based on the technical solution of this utility model, the frame 1 is first installed, with one-third of the frame 1 pre-buried underground and fixed using buried bolts. Then, the traction sheave of the traction machine 7 rotates, driving the steel wire rope 8 to move, causing one side of the parking space frame 3 to descend to the bottom of the corresponding lifting channel 2, while the other side of the parking space frame 3 rises to the top of the corresponding lifting channel 2. At this point, the car frame 4 at the top of one parking space frame 3 and the car frame at the bottom of the other parking space frame 3 are both at the center of the frame 1.

[0023] Next, the drive motor 14 of the fixing mechanism, through gear and rack transmission, causes the support rod 15 to move along the limiting track 13 and insert into the fixing hole 12 on the side wall of the frame 1 to fix the parking frame 3. When a vehicle drives into the surface of the corresponding car frame 4 platform 5, the pressure sensor 9 at the bottom of the platform 5 detects the overall weight of the vehicle. If the vehicle is overweight, the pressure sensor 9 converts the pressure signal into an electrical signal and sends it to the controller 10. The controller 10 then controls the alarm 11 to sound an overweight alarm, prompting the vehicle to leave and change parking spaces. At the same time, the controller 10 adds a dynamic load balancing algorithm during operation. By detecting the weight through the pressure sensor 9, the controller 10 monitors the weight difference on both sides in real time and limits the operation beyond the tolerance. If the vehicle weight does not exceed the set threshold, the controller 10 controls the drive motor 14 to output in reverse, driving the support rod 15 to be pulled out of the fixing hole 12. At the same time, the traction machine 7 works to make the traction wheel rotate in the opposite direction, raising the lower parking frame 3 and lowering the higher parking frame 3, thereby moving the corresponding empty car frame 4 to the center position of the frame 1 for secondary parking.

[0024] Similarly, when it is necessary to drive the vehicle out, the parking space frame 3 can be reversed up and down by the operation of the traction machine 7.

[0025] Finally, it should be noted that, in this utility model, unless otherwise explicitly specified and limited, the terms "installation," "setting," "connection," "fixing," "screw connection," etc., should be interpreted broadly.
