Description

Technical Field

[0001] The present invention relates to the technical field of composite measurement equipment, and in particular to a composite measurement equipment of a laser radar and a camera. Background Art

[0002] A front-view camera is a camera mounted on the front of the vehicle. It's used when parking and allows you to clearly see obstacles in front of the vehicle, making parking easier. Front-view cameras typically produce a true-image image, as opposed to a mirrored image of a rear-view camera. They can be designed with or without reverse markings.

[0003] Existing vehicle-mounted forward-looking binocular cameras and lidars do not have the function of rotation, which means they can only face one direction and are not flexible enough to use. At the same time, the rear cover cannot be removed, making it inconvenient to repair the parts inside the shell.

[0004] Publication number CN215154360U discloses a vehicle-mounted forward-looking binocular camera and laser radar, comprising a mounting base and a housing. A rotating base is welded to the outer wall of the top of the housing, and the rotating base is rotatably connected to the mounting base via a bearing. A driven gear is welded to the outer wall of the top of the rotating base, and a motor is bolted to the inner wall of the top of the mounting base. A driving gear is bolted to the output end of the motor, and the driving gear and the driven gear are meshed with each other. An annular groove is provided on the inner wall of the bottom of the mounting base. When the motor of the present invention drives the driving gear and the driven gear to mesh, the rotating base can drive the housing to rotate, thereby adjusting the angle of the camera and radar. The invention is very flexible to use, and the ball bearings roll inside the annular groove. On the one hand, the ball bearings can provide auxiliary support for the rotating base and the housing, and on the other hand, they can make the rotating base drive the housing to rotate more smoothly, thereby improving stability.

[0005] The above technical solution can effectively realize the coordinated operation of the camera and radar, but it does not have sufficient shock absorption effect, which is not conducive to ensuring the stability of its operation, so it needs to be improved. Summary of the Invention

[0006] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a laser radar and camera composite measurement device.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A laser radar and camera composite measurement device includes a monitoring measurement component, a monitoring radar component is installed on one side of the monitoring measurement component, and the front ends of the monitoring radar component and the monitoring measurement component are arranged flush;

[0009] The upper end of the monitoring and measuring component is detachably connected with a connecting frame component. The upper end of the connecting frame component is fixed with a support plate component. A damping buffer mechanism is arranged on the upper end of the support plate component. A buffer rubber pad is arranged on the damping buffer mechanism. Positioning sliding rods are fixed on both sides of the support plate component. One ends of the two positioning sliding rods are slidably sleeved with sliding sleeve components. The damping buffer mechanism is connected with the two sliding sleeve components;

[0010] One end of the sliding sleeve component is rotatably connected with an inclined swing rod. The upper ends of the two inclined swing rods are jointly rotatably connected with a connecting protection frame. A buffer elastic mechanism is arranged on the sliding sleeve component. The buffer elastic mechanism is connected with the support plate component. A pressure mechanism is arranged on one of the inclined swing rods. The pressure mechanism is connected with the connecting frame component.

[0011] Preferably, in order to facilitate the quick installation and disassembly of the connecting frame component for equipment maintenance and repair, two bolts are rotatably sleeved on one side of the upper end of the monitoring and measuring component. One ends of the two bolts are screwed into the connecting frame component.

[0012] Preferably, in order to convert and buffer external forces, fully reduce the possible vibration of the equipment, fully ensure the stability of the equipment, and improve the measurement accuracy, the damping buffer mechanism includes a damping telescopic component fixed on the support plate component. A top plate is fixed on the damping telescopic component. The buffer rubber pad is fixed on the upper end of the top plate. The buffer rubber pad abuts against the connecting protection frame. Swing rods are rotatably connected to both sides of the lower end of the top plate. The two swing rods are respectively rotatably connected to the two sliding sleeve components.

[0013] Preferably, in order to effectively convert external forces, through the telescopic operation of the first spring, external forces can be effectively absorbed and converted, and in cooperation with the damping telescopic component, external forces can be fully offset. The buffer elastic mechanism includes a first spring sleeved on one end of the sliding sleeve component and the positioning sliding rod. A collar is fixed on the sliding sleeve component. One end of the first spring is fixed on the opposite sides of the support plate component and the collar.

[0014] Preferably, in order to resist the force received at the front end, protect the position of the monitoring component, and avoid the situation of front-end collision during vibration, the connecting protection frame can be used for full protection. The pressure mechanism includes an auxiliary rod rotatably connected to the lower end of one of the inclined swing rods. The auxiliary rod is located on one side of the connecting frame component. A sliding plate is rotatably connected to the lower end of the auxiliary rod. A reset mechanism is jointly arranged between the sliding plate and the connecting frame component.

[0015] Preferably, in order to further convert external force and avoid direct collision between components, the reset mechanism includes a cross bar slidably sleeved on the sliding plate. One end of the cross bar is fixed to one side of the connecting frame assembly, and a second spring is fixedly arranged between the sliding plate and the connecting frame assembly.

[0016] Preferably, in order to facilitate the adjustment of the angle of the connecting and protecting machine frame and expand the monitoring range, a mounting pan-tilt assembly is installed at the upper end of the connecting and protecting machine frame.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. When an external force is transmitted to the connecting and protecting machine frame, the connecting and protecting machine frame will extrude the inclined swing rod, causing the inclined swing rod to push the two sliding sleeve parts to move relatively, which can extrude the first spring, facilitating the conversion of the external force into the potential energy of the first spring. At the same time, when the inclined swing rod operates, the sliding sleeve part will push the swing rod, enabling the top plate to rise. The rising of the top plate can cause mutual extrusion between the top plate and the connecting and protecting machine frame. The buffer rubber pad has a certain flexibility and can receive the pressure of the connecting and protecting machine frame and convert it.

[0019] 2. It is very likely that an external force directly impacts one end of it. When one end of the connecting and protecting machine frame is stressed, the auxiliary rod can be pushed by the inclined swing rod to push the sliding plate to extrude the second spring and move, so as to achieve the purpose of further protection and avoid direct collision between components.

[0020] 3. By installing the pan-tilt assembly, it is convenient to install it in a suitable position, and it is convenient to control the shooting angle of the monitoring and measuring assembly through the pan-tilt assembly to implement dynamic monitoring. Description of the Drawings

Detailed implementation manner

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0028] Refer to Figures 1-5 , the lidar and camera composite measurement device includes a monitoring and measuring component 2. The monitoring and measuring component 2 is a high-definition monitoring camera, which can perform long-term shooting, improve the clear picture, and can process the monitored picture so as to perform calculation and measurement according to the picture structure. A monitoring radar component 4 is installed on one side of the monitoring and measuring component 2. The monitoring radar component 4 and the front end of the monitoring and measuring component 2 are flush. In actual production and preparation, the distance from the object and the shape and position measurements of the object can be understood according to the monitoring radar component 4, and high-quality restoration can be achieved through the cooperation of the monitoring and measuring component 2, so as to fully improve the measurement quality and the measurement effect on the object to be measured.

[0029] Refer to Figures 1-5 , the upper end of the monitoring and measuring component 2 is detachably connected with a connecting frame component 7 for easy quick assembly. Two bolts 8 are rotatably sleeved on one side of the upper end of the monitoring and measuring component 2. One end of each of the two bolts 8 is screwed into the connecting frame component 7. In the actual operation process, the horizontal height of the bolt 8 is at the upper end of the monitoring and measuring component 2, so that the connecting frame component 7 can be made to abut against the upper end of the monitoring and measuring component 2 and move towards the direction of the bolt 8, and the bolt 8 can be rotated to be screwed into the connecting frame component 7 to complete the connection and fixation between the monitoring and measuring component 2 and the connecting frame component 7.

[0030] Refer to Figures 1-5 , the upper end of the connecting frame component 7 is fixed with a support plate member 13. A damping buffer mechanism is provided on the upper end of the support plate member 13, and a buffer rubber pad 9 is provided on the damping buffer mechanism. The damping buffer mechanism can support in the reverse direction and can effectively convert the external force to fully ensure the stability of the monitoring and measuring component 2 to ensure the measurement quality.

[0031] Refer to Figures 1-4, the damping and buffering mechanism includes a damping telescopic assembly 11 fixed on the support plate member 13. A top plate 10 is fixed on the damping telescopic assembly 11. A buffer rubber pad 9 is fixed on the upper end of the top plate 10. The buffer rubber pad 9 abuts against the connecting and protecting frame 1. Two swing rod members 5 are rotatably connected to both sides of the lower end of the top plate 10. The two swing rod members 5 are respectively rotatably connected to two sliding sleeve members 6. When an external force is transmitted, the movement of the sliding sleeve member 6 will push the swing rod member 5 to operate. The swing rod member 5 and the damping telescopic assembly 11 cooperate to enable the top plate 10 to drive the buffer rubber pad 9 to rise. The buffer rubber pad 9 abuts against the connecting and protecting frame 1, and the buffer rubber pad 9 is squeezed and deformed, which can convert the external force for protection.

[0032] Refer to Figures 1-4 , positioning sliding rod members 14 are fixed on both sides of the support plate member 13. One end of each of the two positioning sliding rod members 14 is slidably sleeved with a sliding sleeve member 6. The damping and buffering mechanism is connected to the two sliding sleeve members 6. The positioning sliding rod member 14 can ensure the stability of the movement of the sliding sleeve member 6. One end of the sliding sleeve member 6 is rotatably connected to an inclined swing rod member 16. The upper ends of the two inclined swing rod members 16 are jointly rotatably connected to the connecting and protecting frame 1. A buffer elastic mechanism is provided on the sliding sleeve member 6. The buffer elastic mechanism is connected to the support plate member 13. The buffer elastic mechanism can effectively convert the external force and reduce the impact.

[0033] Refer to Figures 1-4 , the buffer elastic mechanism includes a first spring 12 sleeved on one end of the sliding sleeve member 6 and the positioning sliding rod member 14. A collar 15 is fixed on the sliding sleeve member 6. One end of the first spring 12 is fixed on the opposite sides of the support plate member 13 and the collar 15. When the connecting and protecting frame 1 is stressed, the force of the connecting and protecting frame 1 is transmitted to the inclined swing rod member 16, causing the two sliding sleeve members 6 to move relatively, which can squeeze the first spring 12. The first spring 12 contracts, converting the pressure into its potential energy and slowing down the external force.

[0034] Refer to Figures 1-5, a pressure mechanism is provided on one of the swing rods 16. The pressure mechanism is connected to the connecting frame assembly 7. The pressure mechanism includes an auxiliary rod 17 rotatably connected to the lower end of one of the swing rods 16. The auxiliary rod 17 is located on one side of the connecting frame assembly 7. A sliding plate 18 is rotatably connected to the lower end of the auxiliary rod 17. A reset mechanism is jointly provided between the sliding plate 18 and the connecting frame assembly 7. The reset mechanism includes a cross bar 20 slidably sleeved on the sliding plate 18. One end of the cross bar 20 is fixed to one side of the connecting frame assembly 7. A second spring 19 is jointly fixed between the sliding plate 18 and the connecting frame assembly 7. When the end of the connection protection frame 1 close to the camera is collided, the auxiliary rod 17 will squeeze the sliding plate 18 to contract the second spring 19, further converting the external force for protection. At the same time, the swing rod 16 connected thereto will also operate to push the component to squeeze the first spring 12 for protection, which can effectively prevent the front end of the connection protection frame 1 from colliding with the monitoring and measuring component 2, fully protecting the camera and radar components from being damaged.

[0035] Referring to Figures 1-2 , an installation pan-tilt assembly 3 is installed at the upper end of the connection protection frame 1. The installation pan-tilt assembly 3 is convenient for adjusting the angle of the connection protection frame 1 to expand the monitoring range.

[0036] In the present invention, when installation is required, the staff connects and fixes the connecting frame assembly 7 and the monitoring and measuring component 2 through bolts 8.

[0037] It is effectively connected and fixed to the connection protection frame 1 through the installation pan-tilt assembly 3. The position of the connection protection frame 1 can be well adjusted through the installation pan-tilt assembly 3 to achieve the purpose of the position and angle of the monitoring and measuring component 2, which helps to realize dynamic tracking and monitoring.

[0038] When an external force impacts the connection protection frame 1, the force of the connection protection frame 1 is transmitted to the swing rod 16, causing the two sliding sleeve parts 6 to move relative to each other, which can squeeze the first spring 12. At this time, the movement of the sliding sleeve part 6 can cause the swing rod 5 to push the top plate 10 to rise. The top plate 10 and the connection protection frame 1 squeeze the buffer rubber pad 9 to effectively convert the external force. At the same time, when the end of the connection protection frame 1 close to the camera is collided, the auxiliary rod 17 will squeeze the sliding plate 18 to contract the second spring 19, further converting the external force for protection.

[0039] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
