Description

Technical Field

[0001] This utility model belongs to the field of automated parking system technology, specifically an automated parking system with parking reminder function. Background Technology

[0002] A multi-level parking garage, also known as a mechanical parking system or mechanical automated parking system, is a mechanical or automated equipment system that uses a steel structure as the main frame, combined with lifting and traversing devices, and a control system, to maximize the storage and retrieval of vehicles. It is an effective tool for professional parking lot management companies to increase parking capacity, revenue, and parking fee income.

[0003] Because the parking spaces in multi-level parking garages are relatively small, they require drivers to have good parking skills. When novice drivers attempt to park, even with the help of rearview mirrors and reversing camera systems, they still need to accurately judge the distance between the vehicle and the surrounding environment, often requiring repeated adjustments to the parking space, which reduces parking efficiency to some extent. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-level parking garage with parking reminder function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A multi-level parking garage with parking reminder function includes a foundation, on which a lift cabin and a parking cabin are provided, enclosed by several columns and beams. Several lateral movement devices are provided inside the parking cabin. A lifting device is provided on the top of the lift cabin. A lifting device connected to the lifting device is provided inside the lift cabin. A fixed comb tooth seat is provided on the foundation. The comb teeth of the fixed comb tooth seat are staggered with the comb teeth of the lifting device and are located inside the lifting path of the lifting device. The lifting device can be lowered to a horizontal height lower than the horizontal height of the fixed comb tooth seat. The front comb teeth of the fixed comb tooth seat are provided with I-shaped grooves. An I-shaped support plate is placed on the I-shaped grooves. Return springs are symmetrically provided between the support plate and the I-shaped grooves. A placement groove is provided between two return springs. A pressure sensor is placed in the placement groove. A buzzer electrically connected to the pressure sensor is provided on the foundation.

[0007] Furthermore, a compression spring is also provided in the placement groove. One end of the compression spring abuts against the bottom of the placement groove, and the other end abuts against the bottom of the pressure sensor. A certain amount of space is left between the bottom of the support plate and the top of the pressure sensor.

[0008] Furthermore, the bottom of the I-shaped groove is symmetrically provided with threaded grooves, the bearing plate is symmetrically provided with countersunk holes, a limiting post is provided through the countersunk hole, the bottom of the limiting post is provided with an external thread that is threadedly connected to the threaded groove, the two reset springs are respectively sleeved on the two limiting posts, and the top of the limiting post is provided with a limiting part that cooperates with the countersunk hole.

[0009] Furthermore, the lifting device includes two symmetrical lifting frames. The inner sides of the two lifting frames are provided with a front wheel support comb tooth group and a rear wheel support comb tooth group. Each of the two front wheel support comb tooth groups has a comb tooth that is lower than the other comb teeth. The two lower comb teeth are aligned and respectively located between two extensions on both sides of the bearing plate.

[0010] Furthermore, the crossbeams are crossbeam one arranged in the width direction, crossbeam two arranged in the length direction, and crossbeam three. Crossbeam one, crossbeam two, and crossbeam three are all fixedly connected to two adjacent columns by screws. Crossbeam two is located on the outside and is higher than crossbeam one. Crossbeam one is provided with a slide bar and an electrical component that supplies power to the transverse movement device.

[0011] Furthermore, the transverse movement device includes a transverse comb frame, with several rollers cooperating with slide bars on the outer sides of both ends of the transverse comb frame, and sprocket sets installed on the inner sides of both ends of the transverse comb frame. The two sprocket sets are respectively connected to several rollers at their corresponding ends, and the two sprocket sets are connected by a drive shaft. A drive motor is provided on the transverse comb frame to drive the drive shaft to rotate, and a slide head assembly is installed on the transverse comb frame. The slide head assembly is slidably connected to the electrical components.

[0012] Furthermore, the electrical component includes several support frames connected to a "C"-shaped fixed beam. The fixed beam has an opening facing downwards and a conductive slide rail is installed inside it. The conductive slide rail is slidably connected to the slide head assembly.

[0013] Furthermore, the lifting device includes gear assembly one, gear assembly two, gear assembly three, and gear assembly four symmetrically installed on the top of the lifting chamber. Gear assembly one and gear assembly three are wound with chains and extend downward to connect with two corners of the lifting device. Gear assembly two and gear assembly four are wound with chains and extend downward to connect with the other two corners of the lifting device. Gear assembly one and gear assembly two are connected by a transmission shaft two, which is connected to a drive motor two.

[0014] The beneficial effects of this utility model are:

[0015] This invention features an I-shaped groove on the front teeth of a fixed comb holder, upon which an I-shaped support plate is placed. Symmetrical return springs are positioned between the support plate and the I-shaped groove, lifting the support plate upwards until its upper surface is flush with or slightly below the foundation surface. A placement groove is located between the two return springs, housing a pressure sensor. A buzzer, electrically connected to the pressure sensor, is also located on the foundation. When the vehicle's front wheels slowly approach the support plate, they press down on it, compressing the return springs and causing the front wheels to slightly sink, providing an initial parking indication. Simultaneously, the pressure plate exerts pressure on the pressure sensor below, which transmits the signal to the buzzer, triggering an audible alarm to further remind the driver that the vehicle has reached the designated position. This effectively solves the problem of novice drivers repeatedly adjusting their parking positions due to difficulty in judging the parking location in traditional multi-level parking garages, thus improving parking efficiency.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0030] Please refer to Figure 1-11 ;

[0031] A multi-level parking garage with parking reminder function includes a foundation 1, on which are mounted a lift cabin 3 and a parking cabin 4, which are enclosed by several columns 2 and crossbeams. The parking cabin 4 consists of multiple parking areas, each of which has a lateral movement device 7 for horizontal vehicle transfer. A lifting device 5 is located at the top of the lift cabin 3, and a lifting device 6 connected to the lifting device 5 is located inside the lift cabin 3. The lifting device 5 enables the lifting and lowering of the lifting device 6, thereby completing the vertical transport of vehicles. A fixed comb tooth seat 8 is located on the foundation 1, with the comb teeth of the fixed comb tooth seat 8 interlocking with the comb teeth of the lifting device 6 and positioned inside the lifting path of the lifting device 6. The lifting device 6 can be lowered to a horizontal height lower than the horizontal height of the fixed comb tooth seat 8. The front comb teeth of the fixed comb seat 8 are provided with I-shaped grooves 81. I-shaped support plates 82 are placed on the I-shaped grooves 81. Reset springs 83 are symmetrically arranged between the support plates 82 and the I-shaped grooves 81. The two reset springs 83 push the support plates 82 upward so that their upper end surfaces are flush with or slightly lower than the surface of the foundation 1. A placement groove 84 is provided between the two reset springs 83. A pressure sensor 841 is installed in the placement groove 84. A buzzer 11 electrically connected to the pressure sensor 841 is also provided on the foundation 1. When the front wheels of the vehicle slowly move to the position of the support plate 82, the front wheels will press down on the support plate 82, causing the return spring 83 to be compressed, resulting in a slight sinking of the front wheels, which serves as an initial reminder that the vehicle has arrived at the designated parking position. At the same time, after the support plate 82 is pressed down, it will apply pressure to the pressure sensor 841 below. After receiving the signal, the pressure sensor 841 transmits it to the buzzer 11, which then sounds to further remind the driver that the vehicle has reached the designated position. This effectively solves the problem of novice drivers repeatedly adjusting their parking positions due to the difficulty in judging the parking position in traditional multi-level parking garages, thus improving parking efficiency. The driver then stops the car, turns off the engine, and gets out. He then starts the lifting device 5, which raises the lifting device 6. As the lifting device 6 rises, it transfers the vehicle onto itself and continues to rise vertically above the target parking area so that the lateral movement device 7 can enter below the lifting device 6. Subsequently, the lateral movement device 7 moves laterally from the parking area towards the lifting chamber 3. When the lateral movement device 7 is fully inside the lifting chamber 3, the lifting device 5 drives the lifting device 6 to move downward, so that the horizontal height of the lifting device 6 is lower than the horizontal height of the lateral movement device 7. During this process, the lifting device 6 transfers the vehicle to the lateral movement device 7. Finally, the lateral movement device 7 moves horizontally back to the original parking area, thus completing the parking of the vehicle.When it is time to retrieve the vehicle, simply control the lateral movement device 7 carrying the vehicle to move from the parking area to the same level lift compartment 3. Then, the lifting device 5 drives the lifting device 6 to rise above the lateral movement device 7. During this process, the lifting device 6 can transfer the vehicle onto itself and lift the vehicle above the lateral movement device 7. Then, the lateral movement device 7 moves from the lift compartment 3 back to the original parking area. Finally, the lifting device 5 drives the lifting device 6 carrying the vehicle to descend to below the horizontal level of the fixed comb seat 8 and transfers the vehicle to the fixed comb seat 8.

[0032] In this embodiment, a compression spring 842 is also provided inside the placement slot 84. One end of the compression spring 842 abuts against the bottom of the placement slot 84, and the other end abuts against the bottom of the pressure sensor 841. In the initial state, the compression spring 842 is in a naturally extended state, pushing the pressure sensor 841 upward. The natural extension height of the compression spring 842 is less than the depth of the placement slot 84. Therefore, even if the pressure sensor 841 is pushed up, it will not completely detach from the placement slot 84; only its upper part slightly protrudes from the slot opening. When the support plate 82 is pressed down by the front wheel of the vehicle, the support plate 82 moves downward and contacts the pressure sensor 841, compressing the compression spring 842 and pressing the pressure sensor 841 completely back into the placement slot 84. The signal is transmitted to the buzzer 11, causing the buzzer 11 to sound. When the vehicle leaves, the pressure disappears, the return spring 83 pushes the support plate 82 up, and the compression spring 842 returns to its original state, driving the pressure sensor 841 back to its initial position. In addition, a certain amount of space is reserved between the bottom of the support plate 82 and the top of the pressure sensor 841. When the support plate 82 is not under the pressure of the front wheel of the vehicle, the return spring 83 will lift the support plate 82 to disengage it from the pressure sensor 841. If the buzzer 11 still sounds when there is no vehicle pressure, it indicates that the pressure sensor 841 has detected an abnormal signal, which means that the return spring 83 may have failed. The return spring 83 needs to be checked and replaced in time to ensure the normal operation of the position detection function.

[0033] In this embodiment, the bottom of the I-shaped groove 81 is symmetrically provided with threaded grooves 811, and the bearing plate 82 is symmetrically provided with countersunk holes 821. A limiting post 822 passes through the countersunk hole 821, and the bottom of the limiting post 822 is provided with an external thread that is threaded to the threaded groove 811, thereby realizing the fixed installation of the limiting post 822. Two return springs 83 are respectively sleeved on the two limiting posts 822. When the bearing plate 82 is subjected to pressure and moves downward, it will move vertically downward along the direction of the limiting post 822. The top of the limiting post 822 is provided with a limiting part 823, which cooperates with the countersunk head in the countersunk hole 821 to limit the maximum rising height of the bearing plate 82, and prevent the bearing plate 82 from being excessively lifted due to the excessive natural elongation height of the return spring 83, resulting in the top surface of the bearing plate 82 being higher than the top surface of the foundation 1. Preferably, the upper end face of the limiting part 823 is provided with a hexagonal groove, and the limiting post 822 can be rotated by inserting a hexagonal bar tool into the groove, thereby unscrewing it out of the threaded groove 811, which facilitates the disassembly of the bearing plate 82, so as to replace the reset spring 83 or the compression spring 842, or to inspect and maintain the pressure sensor 841.

[0034] In this embodiment, the lifting device 6 includes two symmetrical lifting frames 61. Each of the two lifting frames 61 has a front wheel support comb tooth assembly 62 and a rear wheel support comb tooth assembly 63 on its inner side. Each of the two front wheel support comb tooth assemblies 62 has a comb tooth positioned lower than the other comb teeth. The two lower comb teeth are aligned and positioned between two extensions on either side of the support plate 82. When the lifting device 6 rises and transfers the vehicle onto it, the lowest points of the vehicle's two front wheels will contact these two lower comb teeth, thereby limiting the movement of the vehicle's front wheels and securing the vehicle during the lifting process.

[0035] In this embodiment, the crossbeams are crossbeam 91 in the width direction, crossbeam 92 in the length direction, and crossbeam 93 in the length direction. Crossbeam 91, crossbeam 92, and crossbeam 93 are all fixedly connected to two adjacent columns 2 by screws. The position between two adjacent crossbeams 91 corresponds to a parking area. Crossbeam 92 is located on the outside and is higher than crossbeam 91. It is used to limit the movement distance of the lateral movement device 7 and prevent it from accidentally sliding out. Crossbeam 93 is used to reinforce the structural strength of the parking area and the lifting chamber 3. Crossbeam 91 is provided with a slide bar 95 and an electrical component 94 that supplies power to the lateral movement device 7.

[0036] In this embodiment, the lateral movement device 7 includes a lateral movement comb frame 71, which serves as the main support for vehicle parking. Several rollers 72 that cooperate with slide bars 95 are provided on the outer sides of both ends of the lateral movement comb frame 71. The lateral movement of the lateral movement comb frame 71 is achieved by the rolling friction between the rollers 72 and the slide bars 95. Sprocket sets 73 are installed on the inner sides of both ends of the lateral movement comb frame 71. The two sprocket sets 73 are respectively connected to several rollers 72 at the corresponding end. The two sprocket sets 73 are connected by a drive shaft 74 to ensure that the rollers 72 on both sides run synchronously. A drive motor 75 is provided on the lateral movement comb frame 71 to drive the drive shaft 74 to rotate. The drive motor 75 drives the drive shaft 74 to rotate, thereby driving the entire lateral movement device 7 to perform lateral displacement. In order to provide continuous power to the drive motor 75, a slider assembly 76 electrically connected to the drive motor 75 is installed on the transverse comb frame 71. The slider assembly 76 is slidably connected to the electrical component 94 and provides power to the drive motor 75 by means of sliding contact power supply.

[0037] The electrical component 94 in this embodiment includes several support frames 941, which are connected to a "C"-shaped fixed beam 942. The fixed beam 942 has its opening facing downwards and a conductive slide rail 943 is installed inside. The conductive slide rail 943 is slidably connected to the slide head assembly 76. The sliding contact power supply technology eliminates the need to connect the drive motor 75 to the power supply device via wires, improving the safety and reliability of the device. For details, please refer to the published technical document "CN105401768A, Sliding Contact Power Supply System and Three-Dimensional Circulating Garage Having the Same". It should be noted that each transverse comb frame 71 has two slide head assemblies 76, and the two slide head assemblies 76 are spaced apart. At the same time, the electrical component 94 is also provided inside the lifting chamber 3. As the traverse device 7 moves from the parking area to the lifting chamber 3, the slider assembly 76 near the lifting chamber 3 gradually detaches from the conductive slide rail 943 in that area. However, the other slider assembly 76 remains in contact with the original conductive slide rail 943, continuing to supply power to the drive motor 75. Before the other slider assembly 76 detaches from the original conductive slide rail 943, the slider assembly 76 that detaches from the original conductive slide rail 943 first will be electrically connected to the conductive slide rail 943 inside the lifting chamber 3. When the traverse device 7 fully enters the lifting chamber 3, both slider assemblies 76 are connected to the conductive slide rail 943 of the lifting chamber 3, thus maintaining a powered state throughout the entire movement process and ensuring the continuity and stability of the traverse device 7's operation.

[0038] In this embodiment, the lifting device 5 includes gear assemblies 51, 52, 53, and 54 symmetrically mounted on the top of the lifting chamber 3. Gear assemblies 51 and 53 are wound with chains and extend downward to connect with two corners of the lifting device 6. Gear assemblies 52 and 54 are wound with chains and extend downward to connect with the other two corners of the lifting device 6. Gear assemblies 51 and 52 are connected by a transmission shaft 55, which is connected to a drive motor 56. When the drive motor 56 is started, it drives the transmission shaft 55 to rotate, causing gear assemblies 51 and 52 to work synchronously. As gear assemblies 51 and 52 operate, they drive gear assemblies 53 and 54 to operate together via their respective chains, thereby achieving simultaneous control of the four corners of the lifting comb device and ensuring that it can move smoothly up and down in the vertical direction.
