Description

Technical Field

[0001] The present invention relates to the technical field of parking space detectors, and in particular to an ultrasonic parking space detector based on the Beidou system. Background Art

[0002] The ultrasonic parking space detector based on the Beidou system is an innovative parking management device that integrates Beidou satellite positioning technology and ultrasonic ranging technology. Through the dual technical architecture of Beidou high-precision positioning combined with ultrasonic real-time detection, it realizes the coordinated optimization of parking space status detection and global navigation of the parking lot.

[0003] The document with the prior art publication number CN221175581U provides a floor-mounted ultrasonic parking space detector. When using this technology, a water-soaked cleaning brush is used to directly clean the cover plate. The sewage after cleaning will flow into the water storage tank along the convex surface. There is no need to dry the surface of the cover plate, thereby saving the time spent by the cleaning staff on drying and increasing the cleaning efficiency. Reducing the drying steps can also improve the enthusiasm of the cleaning staff, avoid the cleaning staff's cleaning enthusiasm being reduced due to the cleaning process being too cumbersome, and ensure the cleaning effect.

[0004] However, when existing technologies are used in outdoor parking spaces, snow and ice easily accumulate on the device surface in snowy conditions. Because existing technologies lack a means to address these accumulations, snow and ice can obscure the ultrasonic sensor's detection area, preventing the proper transmission and reception of ultrasonic signals. This ultimately results in ineffective parking space detection or inaccurate data.

DETAILED DESCRIPTION

[0019] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0020] like Figures 1-8 The Beidou system-based ultrasonic parking detector shown in the figure includes an embedded base 1, with an adjustable base 2 slidingly mounted within it. An ultrasonic sensor 3 is mounted on the adjustable base 2, a push-pull mechanism 4 rotatably mounted within the adjustable base 2, a fixed bracket 5 fixedly mounted on the adjustable base 2, a top cover 6 rotatably mounted above the bracket 5, and multiple pry bars 7 rotatably mounted on the underside of the top cover 6. An ice-breaking mechanism 8 slidably mounted on one side of the pry bars 7, and multiple reciprocating screws 9 rotatably mounted on the underside of the top cover 6. The ultrasonic sensor 3, model SRF05, offers a longer detection range and is suitable for scenarios requiring high accuracy, such as precise parking detection.

[0021] like Figure 3As shown, multiple reinforcing plates 101 are fixedly attached to the outer side of the embedded seat 1. Multiple inverted V-shaped rubber rings 102 are fixedly attached to the top of the embedded seat 1. A motor A103 is fixedly attached to the inner wall of one side of the embedded seat 1. A threaded rod 104 is fixedly attached to the output end of motor A103. A fixed rack 105 is fixedly attached to the inner wall of one side of the embedded seat 1. The reinforcing plates 101 enhance the strength of the embedded seat 1 during embedment. The motor A103 drives the connected threaded rod 104 to rotate, causing the threaded rod 104 to move the adjustment seat 2 connected to the slider 201 upward.

[0022] like Figure 4 As shown, a slider 201 is fixedly connected to one side of the adjustment seat 2 , the slider 201 is threadedly connected to the threaded rod 104 , and a sliding groove 202 is provided on the adjustment seat 2 .

[0023] like Figure 4 As shown, a movable frame 301 is fixedly installed on the ultrasonic sensor 3 , and a slide seat 302 is fixedly connected to one end of the movable frame 301 . The slide seat 302 is slidably matched with the slide groove 202 .

[0024] like Figure 5 As shown, the push-pull mechanism 4 includes a worm 401, which is rotatably connected to the inner wall of the adjustment seat 2, a gear 402 fixedly connected to the outer end of the worm 401, and the gear 402 is meshed with the fixed rack 105 for transmission. A worm wheel 403 is meshed with the inner end of the worm 401, and the worm wheel 403 is rotatably connected to the inner wall of the adjustment seat 2. A connecting rod group 404 is fixedly connected to one end of the worm wheel 403, and the other end of the connecting rod group 404 is rotatably connected to the slide 302. Under the action of the fixed rack 105, the meshing gear 402 drives the connected worm 401 to rotate, so that the worm 401 can drive the connecting rod group 404 connected to the worm wheel 403 to rotate, thereby driving the slide 302 to move, so that the slide 302 drives the ultrasonic sensor 3 on the movable frame 301 to move out from under the top cover 6.

[0025] like Figure 6 As shown, the lower surface of the top cover 6 is provided with a plurality of sealing ring grooves 601, the inner walls of which mate with the outer walls of the inverted V-shaped rubber ring 102. A rotating shaft 602 is fixedly connected to the bottom end of the top cover 6, which is rotatably connected to the fixing frame 5. A motor B603 is fixedly connected to the bottom end of the rotating shaft 602, which is also fixedly connected to the fixing frame 5. The motor B603 drives the top cover 6 connected to the rotating shaft 602 to rotate, allowing snow accumulated on the top cover 6 to be shaken off.

[0026] By providing a rotatable top cover 6 and a sealing ring groove 601 in the top cover 6, when the device is used in an outdoor parking space, the snow on the top cover 6 can be processed. When the top cover 6 rotates, the snow can be shaken off or driven away from the surface of the detector through friction with the snow, preventing snow from accumulating on the surface of the detector, thereby ensuring the normal operation of the ultrasonic sensor 3. The sealing ring groove 601 prevents snow water from seeping into the interior of the detector, which not only solves the problem of interference of snow accumulation on the equipment, but also enhances the long-term reliability of the equipment.

[0027] like Figure 7 As shown, a fixed plate 701 is rotatably connected to one end of the pry bar 7, which is fixedly connected to the top cover 6. An adjustment rack 702 is fixedly connected to the fixed plate 701. A driving shaft 703 is fixedly connected to the end of the pry bar 7 near the inner wall of the embedded seat 1. Transmission grooves 704 are formed on both sides of the other end of the pry bar 7. The pry bar 7 drives the ice-breaking mechanism 8 through the principle of leverage, which is more labor-saving.

[0028] like Figure 8 As shown, ice-breaking mechanism 8 includes an ice-breaking cone 801, which is rotatably connected to top cover 6. A connecting ring 802 is rotatably connected to the outer wall of the middle portion of ice-breaking cone 801. A rubber sleeve 803 is fixedly connected to connecting ring 802. The other end of rubber sleeve 803 is fixedly connected to top cover 6. A movable frame 804 is rotatably connected to the lower end of ice-breaking cone 801. The inner wall of movable frame 804 slides with the outer wall of driving shaft 703. A universal joint 805 is fixedly connected to the bottom end of ice-breaking cone 801. Universal joint 805 is rotatably connected to movable frame 804. One end of universal joint 805 is fixedly connected to adjusting wheel 806, which meshes with adjusting rack 702 for transmission. Rubber sleeve 803 can improve sealing performance. When the pry bar 7 swings back and forth, the driving shaft 703 on the pry bar 7 will drive the ice-breaking cone 801 connected to the movable frame 804 to move up and down, breaking the ice layer above the top cover 6. At the same time, under the action of the adjusting rack 702, the universal joint 805 connected to the adjusting wheel 806 will rotate, so that the universal joint 805 can drive the ice-breaking cone 801 to rotate.

[0029] like Figure 6 、 Figure 7As shown, a transmission wheel 901 is fixedly connected to the bottom end of the reciprocating screw 9, and an annular rack 501 is fixedly connected to the fixed frame 5. The transmission wheel 901 and the annular rack 501 are meshed and transmitted. A push block 902 is slidably provided on the reciprocating screw 9, and both ends of the push block 902 are slidably fitted with the inner wall of the transmission groove 704. When the top cover 6 rotates, it drives the reciprocating screw 9 to rotate. At this time, under the action of the annular rack 501, the reciprocating screw 9 connected to the transmission wheel 901 rotates, causing the reciprocating screw 9 to drive the push block 902 to reciprocate. At this time, the two ends of the push block 902 slide in the transmission groove 704, thereby driving the pry bar 7 to swing back and forth.

[0030] Working Principle: The parking detector uses an ultrasonic sensor 3 installed in the parking space to detect parking spaces. The ultrasonic sensor 3 emits sound waves, detects the reflected waves, and measures the distance from the sensor to obstacles such as cars. By calculating the propagation time of the ultrasonic waves, or the round-trip time, the occupancy status of the parking space can be determined. If the reflected wave indicates that a parking space is occupied, the detector marks the space as "occupied." The Beidou system provides high-precision positioning information, allowing the parking detector to accurately locate each parking space. When integrated with parking lot management systems, Beidou positioning can help car owners or managers quickly query the exact location of parking spaces, thereby improving the efficiency of finding vacant spaces.

[0031] When snow falls, the motor B603 drives the top cover 6 connected to the rotating shaft 602 to rotate, so that the snow on the top cover 6 can be thrown off. At the same time, the rotation of the top cover 6 drives the reciprocating screw 9 to rotate. At this time, under the action of the annular rack 501, the reciprocating screw 9 connected to the transmission wheel 901 rotates, so that the reciprocating screw 9 drives the pushing block 902 to move back and forth. At this time, the two ends of the pushing block 902 slide in the transmission groove 704, thereby driving the pry bar 7 to swing back and forth; When the pry bar 7 swings back and forth, the driving shaft 703 on the pry bar 7 drives the ice-breaking cone 801 connected to the moving frame 804 to move up and down, breaking the ice layer above the top cover 6. At the same time, under the action of the adjusting rack 702, the universal joint 805 connected to the adjusting wheel 806 rotates, so that the universal joint 805 can drive the ice-breaking cone 801 to rotate, thereby improving the ice-breaking efficiency. When the ultrasonic sensor 3 needs to be repaired, the motor A103 is used to drive the connected threaded rod 104 to rotate, so that the threaded rod 104 drives the adjustment seat 2 connected to the slider 201 to move upward; When the ultrasonic sensor 3 is moved out of the embedded seat 1, under the action of the fixed rack 105, the meshing gear 402 will drive the connected worm 401 to rotate, so that the worm 401 can drive the connecting rod group 404 connected to the worm wheel 403 to rotate, thereby driving the slide 302 to move, so that the slide 302 drives the ultrasonic sensor 3 on the movable frame 301 to be moved out from under the top cover 6 for maintenance.
