Description

Technical Field

[0001] This invention belongs to the field of vehicle-mounted laser inspection technology, and particularly relates to a vehicle laser inspection device with anti-collision protection and its application method. Background Technology

[0002] Vehicle-mounted laser detection devices are in-vehicle equipment that utilize laser technology for environmental perception, target detection, or parameter measurement. They are widely used in fields such as autonomous driving, intelligent transportation, and safety assistance systems. Their core function is to emit laser beams and receive reflected signals, combined with data processing technology, to achieve precise detection of the surrounding environment or specific targets.

[0003] In the invention patent application entitled "An Angle Positioning Detection Device for Vehicle-Mounted Scanning Laser Early Warning Radar" (publication number: CN117233731A, publication date: 2023-12-15), the device includes a housing, a rotating plate, a limiting frame, a base, and a drive and angle detection assembly. By incorporating an angle sensor assembly and an angle positioning detection assembly, the angle positioning detection assembly detects the rotation angle of the drive shaft. The rotation of a swing arm triggers the detection of photoelectric sensors. When the swing arm rotation triggers the detection of the two photoelectric sensors, the angle sensor and the stepper motor's step count are corrected. Furthermore, a synchronous belt assembly increases the transmission ratio between the angle sensor assembly, the angle positioning detection assembly, and the drive shaft, increasing the rotation angle of the angle sensor and the swing arm, and thus increasing the swing angle of the swing arm. This facilitates the triggering of the photoelectric sensor detection, thereby improving the stepper motor's step count correction accuracy and increasing the control accuracy of the laser early warning radar's rotation.

[0004] While current laser inspection devices can perform inspections normally, they lack an external protective structure that automatically deploys in the event of a collision. Impacts can easily cause severe damage to the equipment, rendering it unable to function properly and potentially resulting in data loss. Therefore, there is an urgent need for a vehicle laser inspection device with anti-collision protection and its application method. Summary of the Invention

[0005] The purpose of this invention is to address the problem that while current laser inspection devices can perform inspections normally, they lack an external protective structure that automatically erects upon impact. This results in insufficient protection for the device during an impact, easily causing severe damage, malfunction, and data loss, leading to poor practical application. Therefore, this invention proposes a vehicle laser inspection device with impact protection and its application method.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a vehicle laser detection device with anti-collision protection, comprising a mounting cover and a support assembly disposed on the mounting cover, wherein a pneumatic protection mechanism is disposed on the outside of the support assembly, the pneumatic protection mechanism comprising a bottom shell, a feeding pipe fixedly installed on one outer wall of the bottom shell, the interior of the bottom shell being filled with sodium azide powder, and an air hole being disposed on the top surface of the bottom shell, wherein a pneumatic push rod is disposed on the air hole.

[0007] As a further description of the above technical solution:

[0008] The support assembly includes a support column, which is fixedly installed on the top surface of the base plate, and a support plate is fixedly installed at the top of the support column.

[0009] As a further description of the above technical solution:

[0010] An adjustment motor is fixedly installed on the top surface of the support plate, and one end of the output shaft of the adjustment motor is fixedly connected to the bottom surface of the testing machine cover.

[0011] As a further description of the above technical solution:

[0012] The bottom of the mounting cover is provided with a base plate, the base plate is provided with a support component, the top of the support component is provided with a detection machine cover, a camera and a mounting groove are provided on one outer wall of the detection machine cover, and a laser detection head is fixedly installed inside the mounting groove.

[0013] As a further description of the above technical solution:

[0014] A protective cover is fixedly installed at the top of the pneumatic push rod, and an internal air cushion is provided on the inner surface of the protective cover. The protective cover is located outside the adjusting motor.

[0015] As a further description of the above technical solution:

[0016] Two electronic control components are provided on the inner wall of the bottom shell. The electronic control components include a battery box, which is fixedly installed on the inner wall of the bottom shell. Two conductors are fixedly installed on one outer wall of the battery box, and a resistance wire is fixedly installed between the two conductors. The resistance wire and the two conductors are all located inside the shell cavity of the bottom shell.

[0017] As a further description of the above technical solution:

[0018] A touch button is fixedly installed on one inner wall of the battery box, and an adsorption magnetic cylinder is fixedly installed on the other inner wall of the battery box. A touch ball is adsorbed inside the adsorption magnetic cylinder. The touch ball is located on one side of the touch button. The touch button is used to control the current flow between the resistance wire and the two conductors. A top plate is provided on the top surface of the battery box.

[0019] As a further description of the above technical solution:

[0020] The mounting cover has a bottom groove on its bottom surface and a side groove on its side wall. A positioning component is provided in the bottom groove and the side groove. The positioning component includes a first spring and a second spring. The first spring is fixedly installed inside the bottom groove. A pressing block is fixedly installed at one end of the first spring. The pressing block is slidably connected to the bottom groove. One end of the pressing block is located outside the mounting cover.

[0021] As a further description of the above technical solution:

[0022] A side plate is fixedly installed on one outer wall of the pressing block, and a pin is fixedly installed on the bottom surface of the side plate. The second spring is fixedly installed in the side groove, and a positioning block is fixedly installed on one end of the second spring. The positioning block is slidably connected to the side groove. One end of the pin is inserted into a pin hole provided on the bottom surface of the positioning block. An operating rod is fixedly installed on both outer walls of the positioning block. A stroke groove is provided on the outer surface of the mounting cover. One end of the operating rod passes through the stroke groove and extends to the outside of the mounting cover.

[0023] This invention also discloses an application method for a vehicle laser detection device with anti-collision protection, comprising the following steps:

[0024] S1. First, install and position the device. When the device is installed in the installation area, the pressing block will retract inward when it is pressed. At this time, the side plate will move up and the pin will move up until one end of the pin is disengaged from the pin hole on the top surface of the positioning block. At this time, the second spring is no longer restricted and can push the positioning block to move sideways. The positioning block that is pushed out can automatically be inserted into the side slot of the installation area, thereby completing the quick fixation of the whole device.

[0025] S2. During the use of this device, if a vehicle is involved in a collision, the entire device will generate a huge vibration in an instant. The vibration will be transmitted to the pneumatic protection mechanism. At this time, the pressure ball that was originally strongly attached to the magnetic adsorption cylinder will detach from the magnetic adsorption cylinder and slide to one side in an instant of vibration. The pressure ball will directly press the button. The button that is pressed can control the two conductors and the resistance wire to be energized. The energized resistance wire heats up quickly.

[0026] S3. At this time, a large amount of sodium azide powder inside the bottom shell will rapidly expand upon heating, generating a large amount of gas. This high-speed gas will quickly push each pneumatic push rod upwards, and each pneumatic push rod can quickly push the protective cover to the outside of the testing machine cover, thus protecting the testing machine cover.

[0027] S4. At the moment the protective cover pops up, the built-in air cushion can also pop up simultaneously. The built-in air cushion can contact the laser detection head and camera on the outer surface of the detection machine cover, providing secondary protection for important components of the detection structure and preventing damage to important structures.

[0028] S5. When the device is in use, the camera can take pictures of the surrounding environment, the laser detection head can scan the surrounding environment, and then acquire and analyze information on obstacles on the road and transmit it synchronously to the vehicle intelligent terminal. The intelligent terminal analyzes the information, automatically plans the vehicle's route, and makes adjustments in real time.

[0029] S6. When it is necessary to disassemble the device, the disassembly can be completed quickly by moving the positioning block to the side using the operating lever.

[0030] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0031] This invention incorporates a pneumatic protection mechanism. In the event of a vehicle collision, the entire device experiences a tremendous vibration, which is transmitted to the pneumatic protection mechanism. The pressure ball, initially strongly adhered to the magnetic adsorption cylinder, detaches from the cylinder and slides to one side. This pressure ball directly presses against the button, energizing two conductors and a resistance wire. The energized resistance wire rapidly heats up, causing a large amount of sodium azide powder inside the bottom shell to expand rapidly upon heating, generating a large amount of gas. This high-speed gas quickly pushes upwards against the pneumatic push rods, which in turn push the protective cover to the outside of the testing machine cover, providing protection. This design utilizes pneumatic principles to effectively protect the testing machine cover in the instant of a vehicle collision. Compared to traditional protection structures, this protection structure has an extremely short trigger time, significantly improving the protection effect on the equipment.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Please see Figure 1-8 As shown, the present invention provides a vehicle laser detection device with anti-collision protection, including a mounting cover 1, a base plate 10 at the bottom of the mounting cover 1, a support component 6 on the base plate 10, a detection machine cover 5 at the top of the support component 6, a camera 3 and a mounting groove 4 on one outer wall of the detection machine cover 5, a laser detection head 2 fixedly installed inside the mounting groove 4, and a pneumatic protection mechanism 7 on the outside of the support component 6.

[0044] The support assembly 6 includes a support column 64, which is fixedly installed on the top surface of the base plate 10. A support plate 62 is fixedly installed on the top of the support column 64. An adjustment motor 63 is fixedly installed on the top surface of the support plate 62. One end of the output shaft of the adjustment motor 63 is fixedly connected to the bottom surface of the detection machine cover 5.

[0045] The pneumatic protective mechanism 7 includes a base shell 74. A feeding pipe 76 is fixedly installed on one outer wall of the base shell 74. The interior of the base shell 74 is filled with sodium azide powder. An air hole is provided on the top surface of the base shell 74, and a pneumatic push rod 73 is provided on the air hole. A protective cover 71 is fixedly installed on the top end of the pneumatic push rod 73. Two electronic control components 75 are provided on the inner wall of the base shell 74. The electronic control components 75 include a battery box 756, which is fixedly installed on the inner wall of the base shell 74. Two conductors 754 are fixedly installed on one outer wall of the battery box 756. A resistance wire 755 is fixedly installed between conductors 754. The resistance wire 755 and the two conductors 754 are both located inside the cavity of the bottom shell 74. A touch button 753 is fixedly installed on one inner wall of the battery box 756. An adsorption magnetic cylinder 757 is fixedly installed on the other inner wall of the battery box 756. A touch ball 752 is adsorbed inside the adsorption magnetic cylinder 757. The touch ball 752 is located on one side of the touch button 753. The touch button 753 is used to control the current flow between the resistance wire 755 and the two conductors 754. A top plate 751 is provided on the top surface of the battery box 756.

[0046] The specific implementation method is as follows: During the use of this device, if a vehicle collision occurs, the entire device will generate a huge vibration in an instant. The vibration will be transmitted to the pneumatic protection mechanism 7. At this time, the pressure ball 752, which was originally strongly attracted to the magnetic adsorption cylinder 757, will detach from the magnetic adsorption cylinder 757 and slide to one side in an instant of vibration. The pressure ball 752 will directly press the button 753. The button 753, which is pressed, can control the two conductors 754 and the resistance wire 755 to be energized. The energized resistance wire 755 heats up rapidly. At this time, a large amount of sodium azide powder in the bottom shell 74 will rapidly expand in an instant of heating, generating a large amount of gas. This high-speed gas will quickly push each pneumatic push rod 73 upward. Each pneumatic push rod 73 can quickly push the protective cover 71 to the outside of the detection machine cover 5, thus protecting the detection machine cover 5.

[0047] This design utilizes aerodynamic principles to effectively protect the detection hood 5 at the moment of a vehicle collision. Compared to traditional protection structures, this protection structure has an extremely short trigger time, greatly improving the protection effect on the equipment.

[0048] A bottom groove is provided on the bottom surface of the mounting cover 1, and a side groove is provided on the side wall of the mounting cover 1. A positioning component 9 is provided in the bottom groove and the side groove. The positioning component 9 includes a first spring 91 and a second spring 95. The first spring 91 is fixedly installed inside the bottom groove, and a pressing block 92 is fixedly installed at one end of the first spring 91. The pressing block 92 is slidably connected to the bottom groove, and one end of the pressing block 92 is located on the outside of the mounting cover 1. A side plate 93 is fixedly installed on one outer wall of the pressing block 92. A pin 94 is fixedly installed on the bottom surface of 93. The second spring 95 is fixedly installed in the side groove. A positioning block 97 is fixedly installed on one end of the second spring 95. The positioning block 97 is slidably connected to the side groove. One end of the pin 94 is inserted into the pin hole 96 provided on the bottom surface of the positioning block 97. An operating rod 98 is fixedly installed on both outer walls of the positioning block 97. A stroke groove 11 is provided on the outer surface of the mounting cover 1. One end of the operating rod 98 passes through the stroke groove 11 and extends to the outside of the mounting cover 1.

[0049] The specific implementation method is as follows: When positioning and installing the device, the device is directly installed in the installation area. At this time, the pressing block 92 will retract inward when pressed, which will simultaneously drive the side plate 93 to move upward and the pin 94 to move upward until one end of the pin 94 disengages from the pin hole 96 on the top surface of the positioning block 97. At this time, the second spring 95 loses its restraint and can push the positioning block 97 to move sideways. The positioning block 97 can then automatically snap into the side slot in the installation area, thereby completing the quick fixation of the entire device. When it is necessary to disassemble the device, the device can be quickly disassembled by simply moving the positioning block 97 sideways with the operating lever 98. When the device is in use, the camera 3 can take pictures of the surrounding environment, and the laser detection head 2 can scan the surrounding environment to acquire and analyze information on obstacles on the road. The above information can be transmitted to the vehicle intelligent terminal in real time. The intelligent terminal analyzes the information, automatically plans the vehicle's route, and makes adjustments in real time. The above information will also be backed up in the vehicle's infotainment system.

[0050] An internal air cushion 72 is provided on the inner surface of the protective cover 71, and the protective cover 71 is located outside the adjusting motor 63.

[0051] The specific implementation method is as follows: at the moment the protective cover 71 pops up, the built-in air cushion 72 can also pop up synchronously. The built-in air cushion 72 can contact the laser detection head 2 and camera 3 on the outer surface of the detection machine cover 5, which will provide secondary protection for important components on the detection structure, avoid damage to important structures, and further improve the overall self-protection effect of the device.

[0052] This invention also discloses an application method for a vehicle laser detection device with anti-collision protection, comprising the following steps:

[0053] S1. First, install and position the device. Install the device in the installation area. At this time, the pressing block 92 will retract inward when pressed. At this time, the side plate 93 will move upward and the pin 94 will move upward simultaneously until one end of the pin 94 disengages from the pin hole 96 on the top surface of the positioning block 97. At this time, the second spring 95 loses its restraint and can push the positioning block 97 to move sideways. The positioning block 97 that is pushed out can automatically snap into the side slot in the installation area, thereby completing the rapid fixation of the entire device.

[0054] S2. When it is necessary to disassemble the device, the disassembly of the device can be completed quickly by simply moving the positioning block 97 to the side using the operating lever 98.

[0055] S3. During the use of this device, if a vehicle is involved in a collision, the entire device will generate a huge vibration in an instant. The vibration will be transmitted to the pneumatic protection mechanism 7. At this time, the pressure ball 752, which was originally strongly attached to the magnetic adsorption cylinder 757, will detach from the magnetic adsorption cylinder 757 and slide to one side in an instant of vibration. The pressure ball 752 will directly press the button 753. The button 753, which is pressed, can control the two conductors 754 and the resistance wire 755 to be energized. The energized resistance wire 755 will heat up quickly.

[0056] S4. At this time, a large amount of sodium azide powder in the bottom shell 74 will rapidly expand when heated, generating a large amount of gas. This high-speed gas will quickly push each pneumatic push rod 73 upwards, and each pneumatic push rod 73 can quickly push the protective cover 71 to the outside of the testing machine cover 5, thus protecting the testing machine cover 5.

[0057] S5. At the moment the protective cover 71 pops up, the built-in air cushion 72 can also pop up simultaneously. The built-in air cushion 72 can contact the laser detection head 2 and camera 3 on the outer surface of the detection machine cover 5, which provides secondary protection for important components of the detection structure and avoids damage to important structures.

[0058] S6. When the device is in use, the camera 3 can take pictures of the surrounding environment, and the laser detection head 2 can scan the surrounding environment to acquire and analyze information on obstacles on the road. The above information can be transmitted to the vehicle intelligent terminal in real time. The intelligent terminal analyzes the information, automatically plans the vehicle's route, and makes adjustments in real time. The above information will also be backed up to the vehicle's infotainment system in real time.

[0059] Working principle: First, the device is installed and positioned within the installation area. When the device is pressed, the contact block 92 retracts inward, which simultaneously moves the side plate 93 upward and the pin 94 upward until one end of the pin 94 disengages from the pin hole 96 on the top surface of the positioning block 97. At this point, the second spring 95 is no longer restrained and can push the positioning block 97 to move laterally. The extended positioning block 97 can then automatically engage with the side slot in the installation area, thus quickly fixing the entire device. When it is necessary to disassemble the device, simply move the positioning block 97 laterally using the operating lever 98 to quickly disassemble the device.

[0060] During the use of this device, if a vehicle collision occurs, the entire device will generate a huge vibration instantly. This vibration will be transmitted to the pneumatic protection mechanism 7. At this moment, the pressure ball 752, which was originally strongly attracted to the magnetic adsorption cylinder 757, will detach from the magnetic adsorption cylinder 757 and slide to one side during the vibration. The pressure ball 752 will directly press the button 753. The pressed button 753 can control the two conductors 754 and the resistance wire 755 to be energized. The energized resistance wire 755 will heat up rapidly. At this time, the bottom shell 74... A large amount of sodium azide powder will rapidly expand upon heating, generating a large amount of gas. This high-speed gas will rapidly push each pneumatic push rod 73 upwards, which will quickly push the protective cover 71 to the outside of the inspection machine cover 5, thus protecting the inspection machine cover 5. At the moment the protective cover 71 pops up, the built-in air cushion 72 can also pop up simultaneously. The built-in air cushion 72 can contact the laser detection head 2 and camera 3 on the outer surface of the inspection machine cover 5, providing secondary protection for important components of the inspection structure and preventing damage to important structures.

[0061] When the device is in use, camera 3 can take pictures of the surrounding environment, and laser detection head 2 can scan the surrounding environment to acquire and analyze information on obstacles on the road. The above information can be transmitted to the vehicle intelligent terminal at the same time. The intelligent terminal analyzes the information, automatically plans the vehicle's route, and makes adjustments in real time. The above information will also be backed up to the vehicle's infotainment system at the same time.

[0062] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

At this time, a large amount of sodium azide powder in the bottom shell (74) will rapidly expand when heated, generating a large amount of gas. These high-speed gases will quickly push each pneumatic push rod (73) upwards. Each pneumatic push rod (73) can quickly push the protective cover (71) to the outside of the detection machine cover (5) to protect the detection machine cover (5). S4. At the moment the protective cover (71) pops up, the built-in air cushion (72) can also pop up synchronously. The built-in air cushion (72) can contact the laser detection head (2) and camera (3) on the outer surface of the detection machine cover (5), which will provide secondary protection for important components of the detection structure and prevent damage to important structures. S5. When the device is in use, the camera (3) can take pictures of the surrounding environment, the laser detection head (2) can scan the surrounding environment, and then acquire and analyze the information of obstacles on the road and transmit it to the vehicle intelligent terminal in real time. The intelligent terminal analyzes the information, automatically plans the route of the vehicle, and makes adjustments in real time. S6. When it is necessary to disassemble the device, the device can be quickly disassembled by moving the positioning block (97) to the side using the operating lever (98).
