Technical Field

[0002] In traditional parking lots, car owners often need to circle around in the parking lot to find an empty parking space. Due to the scattered layout of parking spaces, car owners have no effective guidance and can only check each area one by one. On average, car owners may need to spend 10 minutes or even longer to find an empty parking space, which not only wastes the car owner's time, but also easily causes traffic congestion in the parking lot. In addition, the parking lot needs to arrange staff for management, including guiding vehicles to park, collecting parking fees, etc. For example, a medium-sized parking lot needs at least 3-5 staff members who work in shifts 24 hours a day, with high labor costs. In addition, some parking spaces can only park one car, and effective hierarchical management and effective parking cannot be carried out, which affects the overall operational efficiency of the parking lot. Therefore, it is urgent to propose a smart parking system and a low-altitude guided drone to improve the above problems, so as to better manage the parking lot and improve the efficiency of parking space utilization. Summary of the invention

A top plate is installed on the top of each inner sliding rod, and the bottom of the inner sliding rod is fixedly connected to the upper platform. The charging component and the positioning and pushing component are both installed on the upper side of the top plate. When the low-altitude guiding drone is parked on the upper side of the top plate, the low-altitude guiding drone is clamped and positioned by the positioning and pushing component, and is pushed to the front side of the charging component for charging; A plurality of infrared detectors are installed in the middle of the lower table and the middle of the upper table to detect whether a vehicle is parked. The outer pole is installed with a controller for controlling the synchronous lifting and lowering of each vertical hydraulic telescopic rod. The controller is electrically connected to the infrared detector, and the controller is connected to the control room electrical signal.

After the rotating rod rotates, it drives the two transverse clamping rods to move relative to each other to clamp and position the low-altitude guided drone on the top plate.

When the two transverse clamping rods are relatively displaced to clamp and position the low-altitude guided drone, the rubber push rod moves backward to push the low-altitude guided drone tightly against the front side of the charging assembly, and charging is performed while correcting the positioning.

[0011] A further improvement based on the above technical solution is that: a plurality of support blocks are fixedly arranged in the middle of the opposite side of two adjacent outer poles, and a clamping assembly is respectively arranged on the left and right sides of the upper table, and after the upper table is raised and lowered, it is clamped on the adjacent support blocks for auxiliary support through the clamping assembly; The card placement assembly includes a mounting frame fixedly connected to the upper table, a plurality of slide grooves are longitudinally opened on both sides of the upper table, and screws are rotatably installed on the front and rear sides of the mounting frame respectively, a longitudinal sliding sleeve is connected to the threaded sleeve on the screw, and a slider is integrally provided on one side of the longitudinal sliding sleeve, and is slidably connected to the slide groove of the upper table through the slider; A transmission motor is installed on the outside of the installation frame, and a worm, a worm wheel and a shaft are installed on the inside of the installation frame, wherein both ends of the shaft are respectively connected to two screw shafts, the worm wheel is fixed in the middle of the shaft, the shaft end of the transmission motor is connected to the worm shaft, and is connected to the worm wheel through the worm.

[0012] It also includes a low-altitude guiding drone, which is applied to the above-mentioned smart parking system. Four relatively arranged L-shaped inclined support rods are installed at the bottom of the low-altitude guiding drone, and the upper sides of the four L-shaped inclined support rods are relatively inclined, so that the overall shape is narrow at the top and wide at the bottom. After the two transverse clamping rods are relatively displaced, they contact the inclined parts of the outer sides of the four L-shaped inclined support rods, and when the rubber push rod is displaced backward, it contacts the inclined parts of the two L-shaped inclined support rods on the front side. A charging port is arranged on the rear side of the low-altitude guiding drone, and the charging port is arranged corresponding to the charging plug.

[0013] Further: A guidance display screen is installed at the bottom center of the low-altitude guidance UAV, and the guidance display screen is connected to the control room via a wireless signal. The guidance display screen is located between four L-shaped inclined support rods, and a ball bearing is embedded in the bottom of the L-shaped inclined support rod and contacts the upper side of the top plate through the ball bearing.

[0014] By adopting the above technical solution, the present invention has the following advantages: The present invention provides a plurality of double-layer parking devices in the parking lot. Both the lower and upper decks of the double-layer parking devices can park vehicles, which can reasonably improve the space utilization rate of the parking lot. In addition, infrared detectors are provided on the lower and upper decks to detect whether there are vehicles parked on the lower and upper decks. When the barrier recognizes a new vehicle, the control room quickly controls the corresponding low-altitude guiding drone on the device to fly to the front and upper part of the new vehicle at the barrier through radio electromagnetic waves, and guides the new vehicle to drive to the corresponding double-layer parking device with vacant space along the planned route, so as to achieve the effect of quickly guiding parking and improve the intelligent management of the parking lot. A guidance display screen is provided on the low-altitude guidance drone, which is used to illuminate and display the corresponding license plate of the guidance vehicle, thereby ensuring the accuracy of the guidance vehicle. Four L-shaped inclined struts are provided at the bottom of the low-altitude guidance drone, which can be better parked on the upper side of the double-layer parking equipment, and can be quickly clamped and pushed to the front side of the charging component by the positioning and pushing component for fixed parking or charging, thereby improving the use stability and endurance of the low-altitude guidance drone; Among them, since the overall shape of the four L-shaped inclined support rods is narrow at the top and wide at the bottom, when the transverse clamping rod of the positioning and pushing assembly is relatively displaced, it can not only push the inclined surface of the four L-shaped inclined support rods to correct the position of the low-altitude guiding drone, but also avoid pushing the four L-shaped inclined support rods to move upward and overturn. At the same time, with the longitudinal displacement of the rubber push rod of the longitudinal pushing structure, the clamped L-shaped inclined support rod can be pushed to the rear side, so as to be pressed against the charging assembly to achieve a stable fixing effect, and the ball embedded in the bottom of the L-shaped inclined support rod can better reduce the friction during movement, improve the smoothness of movement and reduce wear. The longitudinal pushing structure can also cooperate with the charging plug of the charging assembly to directly insert it into the charging port to charge the low-altitude guiding drone. The front and rear positions of the mounting frame plate can be adjusted under the action of the first electric push rod, thereby adjusting the distance and insertion depth between the charging plug and the charging port on the front side of the mounting frame plate, which is more flexible and stable to use. Moreover, the charging plug is elastically arranged on the mounting frame plate through a buffer spring, so it can adapt to the depth of different charging ports, avoiding the wear of the charging port and the charging plug caused by the rigid force generated by the backward displacement of the low-altitude guiding drone, and having a better service life. In addition, a clamping assembly is provided on both sides of the upper table. When the clamping assembly rises to a certain height, it is clamped on each support block through the extended longitudinal sliding sleeve, thereby effectively providing auxiliary support to the upper table, avoiding the upper table from falling and damaging the vehicle due to sudden failure of the vertical hydraulic telescopic rod, and effectively improving the safety of the equipment. At the same time, a roller cylinder is installed at the bottom of the lower table, which can be moved backward under the push of the longitudinal hydraulic telescopic rod, thereby ensuring that the upper table can be moved downward to allow the parked vehicles to drive out, making it more flexible and convenient to use.

DETAILED DESCRIPTION

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0017] like Figure 1-11 As shown, the present invention provides a technical solution for a smart parking system, a smart parking system comprising a control room, a gate 2 connected to the control room, and a plurality of double-layer parking devices 3 arranged in a parking lot and connected to the control room signal, and also comprising a plurality of low-altitude guiding drones 4 connected to the control room wireless signal, the low-altitude guiding drones 4 being parked on the top of the double-layer parking device 3, when the gate 2 identifies the vehicle, the low-altitude guiding drones 4 connected to the control room wireless signal can be quickly activated, the wireless signal can be the 2.4GHz / 5.8GHz ISM frequency band or laser communication and frequency hopping spread spectrum (FHSS) technology in the prior art, since there are a plurality of low-altitude guiding drones 4 and they are parked on the top of the double-layer parking device 3, they can quickly fly to the front of the vehicle to guide the vehicle to the double-layer parking device 3 with vacant space for parking, which greatly shortens the time for the car owner to find a parking space and avoids the traffic congestion caused by the car owner blindly looking for a parking space in the traditional parking lot; Among them, the double-layer parking equipment 3 includes a lower table 31 and an upper table 35 which is movable and arranged on the upper side of the lower table 31. Two infrared detectors 36 are installed in the middle of the lower table 31 and the middle of the upper table 35. The infrared detector 36 can accurately detect whether the parking space is occupied. The control room can accurately command the low-altitude guidance drone 4 to guide the vehicle to the double-layer parking equipment 3 with vacant space based on the information fed back by the infrared detector 36, thereby improving the utilization rate of the parking space. Of course, the infrared detector 36 can also be replaced by an ultrasonic detector in the prior art for detection, and two relatively arranged external poles 32 are respectively provided on the left and right sides of the lower table 31. The external poles 32 are installed with a controller 8 for controlling the synchronous lifting of each vertical hydraulic telescopic rod 321. The controller 8 is electrically connected to the infrared detector 36, and the controller 8 is electrically connected to the control room. The outer pole 32 is connected with the ground at the bottom, and an inner sliding rod 33 is slidably arranged on the inner side of the outer pole 32, and a vertical hydraulic telescopic rod 321 for pushing and pulling the inner sliding rod 33 to slide up and down is installed on one side of the outer pole 32, and a top plate 34 is installed on the top of each inner sliding rod 33, and the bottom of the inner sliding rod 33 is fixedly connected to the upper table 35, so the upper table 35 of the double-layer parking device 3 can be lifted and lowered by the vertical hydraulic telescopic rod 321, and the inner sliding rod 33 on the inner side of the outer pole 32 is fixedly connected to the upper table 35, and the lifting and lowering of the upper table 35 is realized under the pushing and pulling action of the vertical hydraulic telescopic rod 321, and the controller 8 is electrically connected to the infrared detector 36 and can control the synchronous lifting and lowering of the vertical hydraulic telescopic rod 321, which makes the lifting and lowering operation of the upper table 35 flexibly adjustable according to the parking situation of the vehicle, thereby improving the space utilization flexibility of the double-layer parking device 3.

[0018] In this embodiment, a charging component 5 and a positioning and pushing component 6 are installed on the top of the double-layer parking device 3, which are used to fix and clamp the low-altitude guiding drone 4 and automatically charge the low-altitude guiding drone 4. The charging component 5 and the positioning and pushing component 6 are both installed on the upper side of the top plate 34. When the low-altitude guiding drone 4 completes the guiding task, when the low-altitude guiding drone 4 is parked on the upper side of the top plate 34, the low-altitude guiding drone 4 is clamped and positioned by the positioning and pushing component 6, and then pushed to the front side of the charging component 5 for automatic charging, so that the parking and charging operations of the low-altitude guiding drone 4 are automated, reducing manual intervention and improving the drone The efficiency and endurance of the battery are improved; specifically, the charging assembly 5 includes a charging platform 51, a battery 52 and a solar panel 7 installed on the rear side of the top of the top plate 34. The solar panel 7 is electrically connected to the battery 52. ​​The solar panel 7 can convert solar energy into electrical energy and store it in the battery 52, which provides a source of energy for the charging platform 51. For example, in a relatively open environment such as an open-air parking lot, the solar panel 7 has better power generation conditions, which can reduce dependence on external electricity and reduce operating costs. An installation frame 53 is provided on the upper side of the charging platform 51, and a charging plug 54 is movably installed on the front side of the installation frame 53. The charging plug The head 54 is arranged at the rear position of the positioning and pushing component 6. When the low-altitude guiding UAV 4 is docked on the top plate 34, the charging plug 54 corresponds to the charging port 44 on the rear side of the low-altitude guiding UAV 4. Among them, a hollow slot 531 is opened in the middle of the mounting frame plate 53, and the charging plug 54 is movably embedded in the inner side of the hollow slot 531. A buffer spring 55 is installed in the inner side of the hollow slot 531, and is elastically connected to the rear side of the charging plug 54 through the buffer spring 55. When the low-altitude guiding UAV 4 is pressed against the front side of the charging platform 51, due to the possible impact force or slight difference in the docking position, the buffer spring 55 can play a role. The buffering effect prevents the charging plug 54 and the UAV charging port from being worn out due to rigid contact, thereby extending the service life of the charging plug 54 and the UAV charging port 44. The charging platform 51 is longitudinally installed with a first electric push rod 56 connected to the controller 8. The telescopic end of the first electric push rod 56 is connected to the rear side of the mounting frame 53. The controller 8 controls the telescopic movement of the first electric push rod 56 to adjust the front and rear position of the mounting frame 53, thereby adjusting the distance and insertion depth between the charging plug 54 and the charging port 44 on the rear side of the low-altitude guided UAV 4, so that the position of the charging plug 54 can be flexibly adjusted according to the docking situation of the UAV.

[0019] The positioning and pushing assembly 6 includes a rotating rod 61 and a guide rod 62 which are installed on the upper side of the top plate 34 for transverse rotation, and two transverse clamping rods 63 which are longitudinally arranged on the upper side of the top plate 34. The rotating rod 61 and the guide rod 62 are both penetrated by the front sides of the two transverse clamping rods 63, wherein the rotating rod 61 is provided with two opposite threads 611 on both sides, and the two opposite threads 611 are respectively connected with the two transverse clamping rods 63 for threaded transmission. The top plate 34 is provided with a driving motor 612 for driving the rotating rod 61 to rotate, and the driving motor 612 is connected to and controlled by the controller 8. After the rotating rod 61 rotates, it drives the two transverse clamping rods 63 to move relative to each other to clamp and position the low-altitude guiding drone 4 on the top plate 34. This threaded transmission method can achieve more accurate positioning, push the drone to the correct position before charging, make the charging port correspond to the charging plug 54, and improve its accuracy and stability in use. As a further improvement, longitudinal pushing structures 64 are respectively arranged on the rear sides of the two transverse clamping rods 63, and the longitudinal pushing structures 64 include inner grooves 641 opened on the rear sides of the two transverse clamping rods 63, and rubber push rods 642 are longitudinally slidably arranged on the inner sides of the inner grooves 641. The two rubber push rods 642 protrude and are arranged on the opposite sides of the two transverse clamping rods 63. The rear ends of the two transverse clamping rods 63 are installed with second electric push rods 643 electrically connected to the controller 8, and the rubber push rods 642 are pushed and pulled by the second electric push rods 643 to move forward and backward along the inner grooves 641. When the two transverse clamping rods 63 are relatively displaced to clamp and position the low-altitude guiding UAV 4, the rubber push rods 642 move backward to push the low-altitude guiding UAV 4 to the front side of the charging component 5, and charging is performed while correcting the positioning. This can not only correct the position of the UAV, but also make the UAV fit closely with the charging component 5, ensuring that the charging plug 54 can be accurately inserted into the charging port 44 of the low-altitude guiding UAV 4 to achieve stable charging.

[0020] In the above technical solution, parking space display screens 37 for displaying the parking space number and color are respectively installed on the upper and lower sides of the middle part of the left outer pole 32, so that the car owner can quickly and intuitively obtain the parking space number and related status information after entering the parking lot, for example, by color distinction: green means vacant, red means occupied, etc., which is convenient for the car owner to quickly find the designated parking space or find a vacant parking space, thereby improving the efficiency of parking space management; license plate display screens 38 for displaying the license plate number are respectively installed on the upper and lower sides of the middle part of the right outer pole 32, so that the designated parking space can be quickly found, and in this way, the parking lot management personnel can quickly determine the parking position of the vehicle through the license plate display screen 38 later, which is very convenient for vehicle management, inquiry and handling of special situations, such as illegal parking of vehicles and the need to contact the owner urgently. The license plate display screen 38 and the parking space display screen 37 are both connected to and controlled by the controller 8, and the controller 8 can realize centralized management of all display screens. During the operation of the parking lot, for example, when performing operations such as parking space allocation adjustment and vehicle information update, the display screen content can be modified uniformly and quickly, reducing the workload of manual operation one by one, and improving the overall operation and management efficiency of the parking lot.

[0021] In addition, a plurality of roller drums 311 are installed at the bottom of the lower table 31 for transverse rotation, and are in rolling contact with the ground through the roller drums 311. The bottoms of the two outer poles 32 on the left side and the two outer poles 32 on the right side of the lower table 31 are respectively installed with longitudinal hydraulic telescopic rods 322, and are connected to the rear side of the lower table 31 through the telescopic ends of the longitudinal hydraulic telescopic rods 322. The longitudinal hydraulic telescopic rods 322 are connected and controlled by the controller 8, which enables the lower table 31 to be displaced on the ground more easily under the push of the longitudinal hydraulic telescopic rods 322, thereby increasing the flexibility of the movement of the lower table 31, reducing the obstacles that may be encountered when the vehicle drives out, providing convenience for the vehicles in and out of the parking lot, and realizing the efficient operation of the entire double-layer parking equipment 3.

[0022] In this embodiment, a plurality of support blocks 39 are fixedly arranged in the middle of the opposite side of the two adjacent front and rear outer poles 32, and the left and right sides of the upper table 35 are respectively provided with a clamping assembly 350. After the upper table 35 is raised and lowered, it is clamped on the adjacent front and rear support blocks 39 for auxiliary support through the clamping assembly 350. The cooperation between the clamping assembly 350 and the support block 39 enables the bearing pressure of the upper table 35 to be reasonably shared. Compared with the support structure relying solely on the upper table 35 itself, this auxiliary support method can extend the service life of the upper table 35 and the entire double-layer parking device 3, and can effectively enhance the stability of the upper table 35, prevent the upper table 35 from becoming unstable due to shaking or other external factors when parking vehicles, and ensure the safety of vehicle parking. Specifically, the card-releasing assembly 350 includes a mounting frame 351 fixedly connected to the upper table 35, and a plurality of slide grooves 354 are longitudinally provided on both sides of the upper table 35. Screw rods 352 are rotatably installed on the front and rear sides of the mounting frame 351, and a longitudinal sliding sleeve 353 is threadedly sleeved on the screw rod 352, and a slider 3531 is integrally provided on one side of the longitudinal sliding sleeve 353, and is slidably connected to the slide groove 354 of the upper table 35 through the slider 3531. Since the longitudinal sliding sleeve 353 threadedly sleeved on the screw rod 352 is slidably connected to the slide groove 354 of the upper table 35 through the slider 3531, the rotation of the screw rod 352 can accurately control the extension or retraction of the longitudinal sliding sleeve 353. This precise transmission and control method enables the card-releasing assembly 350 to be accurately clamped on the support block 39, thereby realizing a reliable auxiliary support function. In order to achieve synchronous rotation of the two screw rods 352, a transmission motor 355 is installed on the outer side of the installation frame 351, and a worm 356, a worm wheel 357 and a shaft 358 are installed on the inner side of the installation frame 351, wherein both ends of the shaft 358 are respectively connected to the two screw rods 352 shafts, and the worm wheel 357 is fixed in the middle of the shaft 358. The shaft end of the transmission motor 355 is connected to the worm 356 shaft, and is connected to the worm wheel 357 through the worm 356, so that the two screw rods 352 can rotate synchronously with the rotation of the shaft 358. This structure is relatively simple to control, easy to realize automatic control, and more convenient to maintain the equipment, which can reduce maintenance costs and difficulty.

[0023] The utility model also includes a low-altitude guiding drone, which is applied to the above-mentioned intelligent parking system. Four relatively arranged L-shaped inclined support rods 41 are installed at the bottom of the low-altitude guiding drone 4, and the upper sides of the four L-shaped inclined support rods 41 are relatively inclined, so that the overall shape is narrow at the top and wide at the bottom. After relative displacement, the two transverse clamping rods 63 contact the inclined parts of the outer sides of the four L-shaped inclined support rods 41, and the rubber push rod 642 contacts the inclined parts of the two L-shaped inclined support rods 41 on the front side when it moves backward. A charging port 44 is provided on the rear side of the low-altitude guiding drone 4, and the charging port 44 is correspondingly arranged with the charging plug 54, so that the positioning and pushing component 6 can stably clamp, position and push the low-altitude guiding drone 4. This matching relationship ensures that the drone can accurately reach the designated position before charging, ensures that the charging plug 54 is accurately docked with the charging port 44, so that the parking and positioning of the low-altitude guiding drone 4 on the top of the double-layer parking device 3 are more accurate, which helps to improve the operation efficiency of the entire intelligent parking system, and the L-shaped inclined support rod 41 A ball bearing 43 is embedded in the bottom and contacts the upper side of the top plate 34 through the ball bearing 43. When the drone moves on the top plate 34, the ball bearing 43 can reduce friction, making the movement of the drone more flexible, which helps to improve the efficiency of the drone's positioning and charging operations; and a guidance display screen 42 is installed at the bottom center of the low-altitude guidance drone 4. The guidance display screen 42 is connected to the control room through a wireless signal. The guidance display screen 42 is located between four L-shaped inclined support rods 41. In the process of guiding the vehicle to the parking space, the guidance display screen 42 can display guidance information, such as the direction arrow to the parking space, the distance, the license plate of the guiding vehicle, etc., to provide guidance to the car owner more intuitively and enhance the guidance effect. At the same time, the drone can be equipped with existing high-definition / infrared cameras to achieve full-area monitoring of the parking lot, identify abnormal events such as illegal parking and intrusion, and trigger sound and light alarms. It can also detect real-time vehicle information through ultrasonic waves, dynamically plan the optimal parking route, and push navigation instructions to the driver through the guidance display screen 42.

[0024] In a more specific implementation process, after the barrier 2 identifies the vehicle, the control room receives the information of the vehicle's arrival. Since the barrier 2 is connected to the control room, the identification signal can be quickly obtained by the control room. Then, the control room controls the low-altitude guidance drone 4 connected to its signal through a wireless signal. The low-altitude guidance drone 4 is usually parked on the top of the double-layer parking device 3. After receiving the signal, it starts and flies to the front and upper part of the new vehicle at the barrier 2. Two infrared detectors 36 are installed in the middle of the lower table 31 and the upper table 35 of the double-layer parking device 3. The infrared detector 36 can detect whether there is a vehicle parked on the table. The control room determines the double-layer parking device 3 with vacant space through the information fed back by these infrared detectors 36, and then controls the low-altitude guidance drone 4 to fly along the route planned by the system to guide the new vehicle to the corresponding double-layer parking device 3 with vacant space. During the guidance process, since a guidance display screen 42 is installed at the bottom center of the low-altitude guidance drone 4, the guidance display screen 42 is connected to the control room via a wireless signal. The control room can control the guidance display screen 42 to light up and display the corresponding license plate of the guided vehicle, thereby ensuring the accuracy of the guided vehicle, and parking display screens 37 for displaying the position number and color are installed on the upper and lower sides of the middle part of the left outer pole 32, and license plate display screens 38 for displaying the license plate number are installed on the upper and lower sides of the middle part of the right outer pole 32. The license plate display screen 38 and the parking display screen 37 are connected to and controlled by the controller 8. The controller 8 controls the parking display screen 37 to display the corresponding position number and color according to the parking situation of the vehicle and the use of the parking space. For example, the parking display screen 37 on the side of the lower table 31 displays green to indicate an empty parking space, and the parking display screen 37 on the side of the upper table 35 displays red to indicate an occupied parking space, which can be intuitively seen on the spot, and the license plate display screen 38 can be controlled to display the corresponding license plate number, ensuring that the vehicle can determine the corresponding parking position according to this information for parking; After the guidance is completed, after the low-altitude guiding drone 4 flies to the upper side of the top plate 34 of the double-layer parking equipment 3, the positioning and pushing assembly 6 starts to work, and the driving motor 612 in the positioning and pushing assembly 6 drives the rotating rod 61 to rotate. Since the rotating rod 61 is provided with two relative threads 611 on both sides, which are threadedly connected with the two transverse clamping rods 63, the rotating rod 61 drives the two transverse clamping rods 63 to move relative to each other after rotation, and clamps and positions the low-altitude guiding drone 4 on the top plate 34. After the two transverse clamping rods 63 are relatively displaced, they contact the outer inclined parts of the four L-shaped inclined support rods 41 at the bottom of the low-altitude guiding drone 4 to position the drone. In this way, the four L-shaped inclined support rods 41 are positioned and will not move upward and tip over. After the two transverse clamping rods 63 are relatively displaced to clamp and position the low-altitude guiding drone 4, the longitudinal pushing structure The second electric push rod 643 in 64 pushes and pulls the rubber push rod 642 to move backward along the inner slide groove 641, and the rubber push rod 642 contacts the inclined part of the two L-shaped inclined support rods 41 on the front side and pushes the low-altitude guiding drone 4 to move and press it against the front side of the charging component 5, and the ball 43 embedded in the bottom of the L-shaped inclined support rod 41 can better reduce the friction during movement, improve the smoothness of movement and reduce wear, so that the displacement of the drone is more stable and not easy to tip over. The charging plug 54 in the charging component 5 adjusts the front and rear positions under the action of the first electric push rod 56 to adapt to the charging port 44 on the rear side of the low-altitude guiding drone 4, and because the charging plug 54 is elastically arranged on the mounting frame plate 53 by the buffer spring 55, it can adapt to the depth of different charging ports 44 to avoid wear, thereby realizing the charging of the low-altitude guiding drone 4; When the upper table 35 is raised or lowered, since the vertical pole 32 is equipped with a controller 8 for controlling the synchronous raising or lowering of each vertical hydraulic telescopic rod 321, the controller 8 is electrically connected to the infrared detector 36, and the controller 8 is electrically connected to the control room. When the height of the upper table 35 needs to be adjusted, the controller 8 controls the extension and retraction of the vertical hydraulic telescopic rod 321 according to the detection result of the infrared detector 36 or the instruction of the control room, thereby realizing the raising or lowering of the upper table 35, so that the vehicle can enter the upper table 35. After the upper table 35 is raised, the transmission motor 321 in the card release assembly 350 is turned on. The shaft end of 55 is connected to the worm 356 shaft, and is connected to the worm wheel 357 through the worm 356, driving the shaft 358 to rotate. The two ends of the shaft 358 are respectively connected to the two screws 352 shafts, so that the longitudinal sliding sleeve 353 connected by the threaded sleeve on the screw 352 is extended or retracted with the assistance of the sliding connection between the slider 3531 and the slide groove 354 of the upper table 35. When extended, the longitudinal sliding sleeve 353 is clamped on the front and rear adjacent support blocks 39 for auxiliary support, so as to avoid the sudden failure of the vertical hydraulic telescopic rod 321 causing the upper table 35 to fall and damage the vehicle, thereby improving the safety of use; A plurality of roller drums 311 are installed at the bottom of the lower table 31 for transverse rotation, and are in rolling contact with the ground through the roller drums 311. A longitudinal hydraulic telescopic rod 322 is installed at the bottom of the two outer poles 32 on the left side and the two outer poles 32 on the right side of the lower table 31 respectively, and is connected to the rear side of the lower table 31 through the telescopic end of the longitudinal hydraulic telescopic rod 322. The longitudinal hydraulic telescopic rod 322 is connected to and controlled by the controller 8. When it is necessary to allow the vehicle parked on the upper table 35 to drive out, the controller 8 controls the longitudinal hydraulic telescopic rod 322 to push the lower table 31 to move backward, thereby ensuring that the upper table 35 can move downward to allow the vehicle to drive out.
