Description

Technical Field

[0001] The invention relates to the technical field of vehicle distance measurement, in particular to an intelligent vehicle distance measurement device. Background Art

[0002] When vehicles are driving on the road, the distance between vehicles is measured. After the measurement information is exchanged, the road capacity can be improved, the road congestion can be reduced, and the road can be smoother. In actual vehicle distance measurement, intelligent vehicle distance measurement devices are often required. On highways, intelligent vehicle distance measurement devices are usually installed on gantry frames; The laser radar in the intelligent vehicle distance measurement device mainly determines the vehicle distance by receiving pulse signals. When the laser radar is working, it can not only measure the vehicle distance, but also count the vehicles, which provides convenience for traffic flow management. At the same time, the laser radar also has the function of vehicle speed detection, which helps to maintain the overall traffic order of the road. In addition, when the laser radar is working, it can be connected to the highway data management center, so that the highway data management center can timely understand the vehicle situation on the road site, which is convenient for highway management personnel to better manage road conditions, and also convenient for law enforcement departments to better retain evidence and facilitate the handling of illegal accidents; For example, the application number CN201821521200.1 is a device for collecting evidence of violations of high-speed vehicles that do not meet the safety distance requirements. When working, it provides a device for collecting evidence of violations of high-speed vehicles that do not meet the safety distance requirements, which can accurately and timely detect violations and avoid misidentification; There is also a safe speed and distance warning system for highways with application number CN201620233005.3, whose central processing unit system is connected to the vehicle distance confirmation system and the early warning display system respectively, which is conducive to protecting the driver's driving safety and reducing traffic accidents, and ensuring traffic safety; And a highway congestion 5G network prediction system based on ETC gantry with application number CN202110076853.3, which detects vehicles on the highway at a fixed distance through the data acquisition module, while the main display module and the auxiliary display module in the warning module remind the rear vehicles of the speed and distance, so that the ETC gantry, 5G network and congestion prediction are well combined; During use, if the radar can follow the measured vehicle, the measurement accuracy will be higher. However, the device in the above application does not have the radar following function during use, which leads to insufficient measurement accuracy and brings unnecessary trouble to the vehicle distance measurement.

[0014] Preferably, through holes are provided on the surface of the warning plate, and the through holes are distributed on the surface of the warning plate at equal intervals.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the intelligent vehicle distance measuring device adopts a new structural design. When working, the device box and the laser radar are driven to rotate by the motor, the long pin, the first bevel gear and the second bevel gear. At this time, the laser radar can follow the measured vehicle, and then multiple measurements can be performed, thereby improving the measurement accuracy. At the same time, when the device box rotates, the knocking block will hit the copper plate, and the copper plate will make a sound, which plays a role in driving away birds, preventing bird droppings from remaining on the working plate, thereby preventing the working plate from being corroded, and extending the service life of the entire device. In addition, a swingable warning plate is provided, which cooperates with the copper plate to optimize the bird-driving effect, thereby optimizing the anti-corrosion effect. The specific contents are as follows: (1) When the intelligent vehicle distance measuring device is in use, when the laser radar is required to work, the sensor controller inside the device box controls the motor, and the motor drives the connecting shaft to rotate through the long pin, the first bevel gear and the second bevel gear. When the connecting shaft rotates, the device box and the laser radar are driven to rotate slowly. At this time, the laser radar can follow the vehicle and perform multiple measurements, thereby improving the measurement accuracy; (2) In the intelligent vehicle distance measuring device, bird droppings will corrode the working plate, and when the connecting shaft rotates, the connecting shaft will drive the cam to rotate synchronously, and then the cam will intermittently push the movable plate. When the movable plate is pushed, the movable plate rises under the action of the limit column. At this time, the connecting spring is squeezed, and when the cam continues to rotate until it is no longer in contact with the movable plate, the movable plate falls under the action of its own gravity and the connecting spring. That is, the movable plate performs reciprocating linear motion in the vertical direction under the action of the cam thrust, its own gravity, the limit column and the connecting spring. At this time, the movable plate will drive the striking block to strike the copper plate inside the auxiliary plate again and again, causing the copper plate to make a sound. At this time, the copper plate plays a warning role, keeping the birds away from the working plate, thereby preventing droppings from remaining on the working plate, thereby extending the overall service life of the device; Furthermore, the striking blocks are evenly spaced on the lower surface of the movable plate, which optimizes the striking effect and thus optimizes the bird-repelling effect; Furthermore, during the movement of the movable plate, the limit plate on the lower surface of the limit column limits the moving distance of the movable plate, so that the movable plate will not fall, thereby ensuring the working stability of the movable plate and the knocking block; (3) In the intelligent vehicle distance measuring device, when the movable plate performs reciprocating linear motion in the vertical direction, the movable plate drives the column to move synchronously. When the column moves, it drives the external rod to slide inside the guide groove. At this time, the vertical rod and the rotating shaft rotate under the action of the external rod and the guide groove, and then the vertical rod drives the warning plate to rotate through the connecting rod. At this time, the warning plate also plays a role in driving away birds. The warning plate and the copper plate cooperate to optimize the effect of driving away birds. Furthermore, when the shaft rotates, the torsion spring will be stretched, and the torsion spring plays a role in assisting the shaft to rotate. At the same time, the evenly spaced through holes not only reduce the gravity of the warning plate, but the wind sound formed by the air passing through the through holes also has the effect of repelling birds.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

When the tracking component is working, the laser radar 7 follows the measured vehicle and performs multiple measurements; A warning component is provided on the lower surface of the working plate 2, and the warning component includes a cam 13 fixedly connected to the end of the other side of the connecting shaft 6, and a driving component is provided on the upper surface of the working plate 2, and the driving component includes a rotating shaft 21 rotatably provided on the upper surface of the working plate 2. When the warning component and the driving component are working, a sound is made to drive away flying birds and avoid the residue of bird droppings.

[0020] The output end of the motor 3 is fixedly connected with a long pin 8 , and the end of the long pin 8 is fixedly connected with a first bevel gear 9 corresponding to the second bevel gear 28 . Baffles 10 are fixedly connected to both sides of the connecting shaft 6 , and the baffles 10 are in contact with the surface of the connecting plate 5 .

[0021] During use, when the laser radar 7 is needed to work, the induction controller inside the equipment box 4 controls the motor 3 on the lower surface of the working plate 2. At this time, the motor 3 drives the connecting shaft 6 to rotate inside the connecting plate 5 through the long pin 8, the first bevel gear 9 and the second bevel gear 28 (when the connecting shaft 6 rotates, the baffle 10 makes the connecting shaft 6 rotate more stably). When the connecting shaft 6 rotates, it drives the equipment box 4 and the laser radar 7 to rotate slowly. At this time, the laser radar 7 can follow the vehicle and perform multiple measurements, thereby improving the measurement accuracy.

[0024] The droppings of birds will corrode the working plate 2, and when the connecting shaft 6 rotates, the connecting shaft 6 will drive the cam 13 to rotate synchronously, and then the cam 13 will intermittently push the movable plate 15. When the movable plate 15 is pushed, the movable plate 15 rises under the action of the limit column 14. At this time, the connecting spring 18 is squeezed, and when the cam 13 continues to rotate until it is no longer in contact with the movable plate 15, the movable plate 15 falls under the action of its own gravity and the connecting spring 18, that is, the movable plate 15 performs reciprocating linear motion in the vertical direction under the action of the thrust of the cam 13, its own gravity, the limit column 14 and the connecting spring 18, and at this time the movable plate 15 will drive the knocking The block 16 repeatedly hits the copper plate 12 inside the auxiliary plate 11, causing the copper plate 12 to make a sound. At this time, the copper plate 12 serves as a warning, keeping the birds away from the working plate 2, thereby preventing feces from remaining on the working plate 2, and extending the service life of the entire device. The striking blocks 16 are evenly spaced on the lower surface of the movable plate 15, thereby optimizing the striking effect and thus optimizing the bird-repelling effect. At the same time, during the movement of the movable plate 15, the limiting plate 17 on the lower surface of the limiting column 14 limits the moving distance of the movable plate 15, so that the movable plate 15 will not fall, thereby ensuring the working stability of the movable plate 15 and the striking blocks 16.

[0025] Embodiment 3: Different from Embodiment 2, the warning plate 26 and the through hole 27 are provided to achieve a better bird-repelling effect. Figure 7-Figure 9 As shown: The driving assembly also includes a column 19 fixedly connected to the upper surface of the movable plate 15, and the column 19 passes through the interior of the working plate 2, a vertical rod 22 is fixedly connected to the upper surface of the rotating shaft 21, and a guide groove 23 is opened on the surface of the vertical rod 22, and the left and right sides of the column 19 are fixedly connected to external rods 20, and the external rods 20 correspond to the guide grooves 23 one by one.

[0026] The end of the external rod 20 is located inside the guide groove 23. The driving assembly also includes a connecting rod 25 fixedly connected to the surface of the vertical rod 22, and the end of the connecting rod 25 is fixedly connected to a warning plate 26.

When the column 19 rises, the column 19 will drive the external rod 20 to slide inside the guide groove 23 on the surface of the shaft 21. At this time, the vertical rod 22 and the shaft 21 rotate under the action of the external rod 20 and the guide groove 23, and then the vertical rod 22 drives the warning plate 26 to rotate through the connecting rod 25. When the shaft 21 rotates, the torsion spring 24 will be stretched, and the torsion spring 24 plays an auxiliary role in the shaft. 21 rotates. When the column 19 descends, the shaft 21 rotates under the action of the torsion spring 24, the external rod 20 and the guide groove 23, so that the warning plate 26 is in a swinging state. The warning plate 26 plays a role in driving away the birds. At the same time, the through holes 27 evenly distributed on the surface of the warning plate 26 not only reduce the gravity of the warning plate 26, but also the wind sound formed by the air passing through the through holes 27 also has the effect of driving away birds. At this time, the warning plate 26 and the copper plate 12 cooperate to optimize the effect of driving away birds.
