Description

Technical Field

[0001] This invention relates to the field of intelligent garage auxiliary devices, and in particular to a vehicle detection and automatic centering device. Background Technology

[0002] With the development of the times, automated parking garages are becoming increasingly common, and many places have built such garages. Because they are intelligent and automated parking systems, the requirements for the accuracy and safety of the transmission during parking are much higher. A slight mistake could lead to a safety accident. Solving the problems of parking position accuracy and safety stability during the parking process is of paramount importance. Moreover, the existing parking space transmission structure is not good enough in terms of centering. As people's living standards improve, their safety requirements are also increasing. Automated parking equipment will inevitably have stricter requirements in this regard. Furthermore, when moving the vehicle after centering, the left and right drive modules are softly connected. If the speed of one side is uneven, there is a risk of the vehicle falling off. To address this, we propose a vehicle detection and automatic centering device. Summary of the Invention

[0008] Preferably, the lifting system includes a liftable vehicle stop assembly located on the upper side of the corresponding roller positions on the left and right body frames. An electric push rod is provided on the side of the vehicle stop assembly and is fixedly connected to the inside of the left and right body frames. A pin is provided between the vehicle stop assembly and the electric push rod.

[0012] Preferably, the distance detection system includes a rotatable rotating platform disposed on the side of the left body frame near the right body frame, a fixed rod fixedly installed on the side of the rotating platform, a distance sensor fixedly installed on the side of the fixed rod away from the rotating platform, and a mating piece fixedly installed on the side of the right body frame near the left body frame corresponding to the position of the distance sensor.

[0013] Beneficial effects

[0014] This invention provides a vehicle detection and automatic centering device. It has the following advantages:

[0015] (1) The vehicle detection and automatic centering device guides the vehicle to the designated position via the approach bridge. The functional detection system detects the vehicle. Through the cooperation of the chassis detection module, the first light curtain assembly, and the second light curtain assembly, the chassis detection module detects the vehicle chassis height, and the first and second light curtain assemblies detect the front and rear tires. At the same time, the lifting system extends and retracts. Through the cooperation of the electric push rod, the vehicle blocking rod assembly, and the pin shaft, the electric push rod extends and retracts to push the vehicle blocking rod assembly vertically upward to stop the vehicle. The power system centers the vehicle through the cooperation of the front drive assembly, the front centering rod, the drive shaft, the rear drive assembly, and the rear centering rod. The front drive assembly drives the front centering rod to push to the side of the vehicle tires. Through the linkage of the drive shaft, the rear drive assembly pushes the rear centering rod to the side of the vehicle tires. Finally, the drive rail system moves the vehicle to the garage through the cooperation of the drive motor, drive gear, and track plate. This makes parking easier. The driver only needs to park the vehicle on the platform and does not need to worry about the left and right positions.

[0016] (2) When the vehicle is moved to the garage, the vehicle detection and automatic centering device uses a rotating table, a fixed rod, a distance sensor and a mating plate to rotate and drive the fixed rod to swing 90 degrees so that the distance sensor and the mating plate can make contact signals. The distance range of the distance sensor and the mating plate is used to determine whether the speed of the left and right body frames is normal, and the speed of the left and right body frames is changed accordingly. This avoids the vehicle from falling off the left and right body frames and being damaged due to asynchronous operation of the left and right body frames.

[0017] (3) When the vehicle is moved to the garage, the drive gears of the left and right body frames mesh with the track plate during the movement. Through the cooperation of the connecting rod, lower contact block, upper contact block, counter and reset spring, the track plate squeezes the connecting rod to push the lower contact block to contact the upper contact block to trigger the counter to count. The reset spring resets the lower contact block. The counting frequency determines which group of the left and right body frames has abnormal speed. At the same time, if one group of counters does not show a counting signal after the drive gear and track plate mesh for one revolution, it can be determined whether there is misalignment between the drive gear and the track plate.

[0035] Furthermore, such as Figure 6As shown, the functional detection system 3 includes a rectangular frame 31 that is vertically and equidistantly fixed to the sides of the left body frame 1 and the right body frame 2. Photoelectric sensors 32 are equidistantly arranged at multiple angles on the sides of the frame 31. These photoelectric sensors 32 are existing technology and will not be described in detail here. A chassis detection module 33 is located between the left body frame 1 and the right body frame 2. The chassis detection module 33 consists of multiple distance sensors, a camera, and a protective box.

The front drive assembly 41 consists of a motor, a fixed shaft, gears and chains, and the rear drive assembly 42 consists of a fixed shaft, gears and chains. The power is connected between them through the drive shaft 43. The front drive assembly 41 drives the front centering rod 44 to push and the drive shaft 43 to rotate. The drive shaft 43 drives the rear drive assembly 42 to drive the rear centering rod 45 to push synchronously, which plays a role in pushing and centering the vehicle. The limit switch 36, the proximity switch 37 and the push rod detection switch 38 play a role in monitoring the position status of the front drive assembly 41.

[0037] Furthermore, such as Figure 8As shown, the lifting system 5 includes a liftable vehicle blocking rod assembly 51 located on the upper side of the corresponding roller 9 positions on the left side frame 1 and the right side frame 2. The vehicle blocking rod assembly 51 is composed of multiple rectangular plates and a rotating shaft. The vehicle blocking rod assembly 51 can be folded and extended under power drive to limit the vehicle. An electric push rod 52 is provided on the side of the vehicle blocking rod assembly 51 and is fixedly connected to the inside of the left side frame 1 and the right side frame 2. A pin 53 is provided between the vehicle blocking rod assembly 51 and the electric push rod 52 and the vehicle blocking rod assembly 51 and the electric push rod 52 are connected together through the pin 53. The electric push rod 52 extends and extends to push the vehicle blocking rod assembly 51 vertically upward to stop the vehicle.

[0038] Furthermore, such as Figure 9 As shown, the drive track system 7 includes a drive motor 71 fixedly installed on the sides of the left side frame 1 and the right side frame 2. A drive gear 72 is fixedly connected to the side of the drive motor 71 and meshes with the distance detection system 6. The drive motor 71 and the drive gear 72 are existing technologies and will not be described in detail here. Detection components 73 are equidistantly arranged at the root of the drive gear 72. A track plate 74 is arranged on the lower side of the left side frame 1 and the right side frame 2 and meshes with the drive gear 72.

[0039] Furthermore, such as Figure 10 As shown, the detection component 73 includes a mounting groove 731 formed at the root of the drive gear 72. The mounting groove 731 is a rectangular groove. A movable connecting rod 732 is disposed inside the mounting groove 731 and extends through the drive gear 72. The connecting rod 732 is a circular rod with one side spherical. A counter 733 is fixedly installed on the bottom wall inside the mounting groove 731. The counter 733 is existing technology and will not be described in detail here. An upper contact block 734 is fixedly connected to the upper side of the counter 733 and is located inside the mounting groove 731. A movable lower contact block 735 is disposed inside the mounting groove 731 corresponding to the position of the upper contact block 734. The contact block 734 and the lower contact block 735 are rectangular blocks. The lower contact block 735 is connected to the connecting rod 732 by a threaded connection. A return spring 736 is fixedly connected between the side of the lower contact block 735 and the inner wall of the mounting groove 731. The return spring 736 is sleeved on the side of the connecting rod 732. The return spring 736 is existing technology and will not be described in detail here. The track plate 74 presses the connecting rod 732 to push the lower contact block 735 to slide into contact with the upper contact block 734 in the mounting groove 731, triggering the counter 733 to count the signal and feed it back to the controller. The frequency of the count interval helps to determine which group of the left body frame 1 and the right body frame 2 has abnormal speed. The return spring 736 plays a reset role for the lower contact block 735.

[0040] Furthermore, such as Figure 11As shown, the distance detection system 6 includes a rotatable rotating platform 61 located on the side of the left body frame 1 near the right body frame 2. The rotating platform 61 is existing technology and will not be described in detail here. A fixed rod 62 is fixedly installed on the side of the rotating platform 61. The fixed rod 62 is a circular rod. A distance sensor 63 is fixedly installed on the side of the fixed rod 62 away from the rotating platform 61. The distance sensor 63 is model BJ15M-TDT. A mating piece 64 is fixedly installed on the side of the right body frame 2 near the left body frame 1, corresponding to the position of the distance sensor 63. The mating piece 64 is a rectangular block. The rotation of the rotating platform 61 causes the fixed rod 62 to swing 90 degrees, so that the distance sensor 63 and the mating piece 64 make contact and the signal is fed back to the external controller, detecting that the relative position between the left body frame 1 and the right body frame 2 remains unchanged.

[0041] Working principle of the invention:

[0042] In operation, firstly, an external controller electrically connected to the inner sides of the left and right side frames 1 and 2 is installed. When a vehicle enters the entrance / exit position, the system automatically detects the vehicle and recognizes the license plate, simultaneously opening the gate. The vehicle then passes through the ramp 8 onto the upper roller 9 of the left and right side frames 1 and 2. The function detection system 3 detects the vehicle to facilitate its allocation to a suitable parking position. The chassis detection module 33 detects the vehicle's chassis height and feeds the feedback to the controller. The photoelectric sensor 32 on the side of the mounting bracket 31 detects the vehicle's front and rear overlength, presence of other vehicles, and accidental entry by personnel and feeds the feedback to the controller. The first light curtain assembly 34 and the second light curtain assembly 35 detect the front and rear tires to determine whether they have reached the designated area and feed the feedback to the controller. Simultaneously, the lifting system 5 extends and retracts, allowing the vehicle to enter and stop at the corresponding position. The controller controls the electric push rod 52 to extend... The retractable braking rod assembly 51 extends vertically upward to stop the vehicle. Then, the power system 4 centers the vehicle. The controller controls the front drive assembly 41 to drive the front centering rod 44 to the side of the vehicle's tires. The transmission shaft 43 transmits the power to the rear drive assembly 42 to push the rear centering rod 45 to the side of the vehicle's tires. The limit switch 36, proximity switch 37, and push rod detection switch 38 monitor the position of the front drive assembly 41, thus horizontally pushing the vehicle for centering. The roller 9 facilitates vehicle movement. Finally, the drive track system 7 drives the left side frame 1 and right side frame 2 to move the vehicle into the garage. The controller controls the drive motor 71 to drive the drive gear 72 to rotate and mesh with the track plate 74 for driving. This makes parking easier, as the driver only needs to park the vehicle on the platform without worrying about its left or right position.

[0043] When the vehicle is moved into the garage, the controller controls the rotating platform 61 to rotate, causing the fixed rod 62 to swing 90 degrees. This causes the distance sensor 63 and the mating piece 64 to make contact, and the signal is fed back to the external controller. When the left side frame 1 moves slowly or the right side frame 2 moves quickly, the distance between the distance sensor 63 and the mating piece 64 deviates from the normal range and increases, driving the left side frame 1 to speed up or the right side frame 2 to slow down. If the distance does not return to the normal range after two seconds, the controller controls the drive track system 7 to stop running. When the right side frame 2 moves slowly or the left side frame 1 moves quickly, the distance between the distance sensor 63 and the mating piece 64 deviates from the normal range and decreases, driving the right side frame 2 to speed up or the left side frame 1 to slow down. If the distance does not return to the normal range after two seconds, the controller controls the drive track system 7 to stop running. This prevents the vehicle from falling off the left side frame 1 and right side frame 2 due to asynchronous operation, thus avoiding damage.

[0044] When the vehicle is moved into the garage, the drive gear 72 of the left body frame 1 and the right body frame 2 engages with the track plate 74 during movement. The track plate 74 presses the connecting rod 732, pushing the lower contact block 735 to slide into the mounting groove 731 and contact the upper contact block 734, triggering the counter 733 to count and send a signal to the controller. The reset spring 736 resets the lower contact block 735. When not engaged, the lower contact block 735 and the upper contact block 734 do not contact each other. The frequency of the counting interval helps to determine which set of speeds of the left body frame 1 and the right body frame 2 is abnormal, which helps the controller to determine the speed of the left body frame 1 and the right body frame 2 and adjust the speed accordingly. At the same time, if one set of counters 733 does not show a counting signal after the drive gear 72 and the track plate 74 have engaged for one revolution, it can be determined whether there is misalignment between the drive gear 72 and the track plate 74.
