Description

Technical Field

[0001] This invention relates to the field of smart devices, and in particular to a road obstacle recognition device. Background Technology

[0002] Intelligent devices are electronic devices that possess computing power, can sense their environment, analyze data, and make autonomous decisions. They typically connect to networks or other devices via wireless protocols and are widely used in fields such as home, healthcare, and transportation. Roadblock recognition devices are also a type of intelligent device. On unmanned delivery vehicles, cameras are usually installed as roadblock recognition devices to quickly identify roadblocks. However, traditional roadblock recognition devices do not have automatic cleaning components, making it impossible to automatically and quickly clean the camera's external protective cover. This results in dirt damaging the camera's external protective cover, affecting the camera's normal operation and making it unable to accurately identify roadblocks. This directly affects the normal and accurate operation of the unmanned delivery vehicle and poses a significant safety hazard.

[0003] To address the aforementioned problems, this invention provides improvements. Summary of the Invention

Both the second and fourth pipes are equipped with one-way valves. A circular sleeve is fixed to the bottom of the transparent protective cover. Multiple sets of teeth are evenly fixed to the bottom of the inner cavity of the circular sleeve. A drive motor is fixed to the auxiliary seat via a side frame.

[0027] Example

[0028] A roadblock recognition device includes a bracket 1 fixed to an unmanned delivery vehicle. A disc 2 is fixed to the top right side of the bracket 1, and an auxiliary seat 3 is fixed to the disc 2. A transparent protective cover 4 is rotatably mounted on the auxiliary seat 3. A camera 5 for recognizing roadblocks is installed inside the transparent protective cover 4. A water tank 25 and a placement frame 19 are fixed sequentially along the left-right direction on the front of the inner cavity of the bracket 1. A waterproof cover is fixed to the right side of the water tank 25, and a controller is installed inside the waterproof cover. A base frame 10 is rotatably mounted on the bottom surface of the transparent protective cover 4. The bottom end of the base frame 10 is fixed to the disc 2. An auxiliary cleaning component is installed on the base frame 10. The auxiliary cleaning component includes a scraper 11 located on one side of the base frame 10 and attached to the transparent protective cover 4. An L-shaped nozzle 16 located on the back of the transparent protective cover 4 is embedded in the top of the scraper 11. Multiple sets of spray holes 1 are opened at both the bent end and the vertical end of the top of the L-shaped nozzle 16. 7. A water pump 20 and an air pump 21 are fixed sequentially in the left and right directions inside the placement frame 19. The inlet end of the water pump 20 is connected to the bottom of the front of the water tank 25 through the first pipe. The outlet end of the water pump 20 is connected to the second pipe 22. One end of the second pipe 22 passes through the bracket 1 and is rotatably mounted with a third pipe 18 whose top end is connected to the L-shaped nozzle 16. The air inlet end of the air pump 21 is connected to an air inlet pipe that passes through to the outside of the placement frame 19. The air outlet end of the air pump 21 is connected to the fourth pipe 23. One end of the fourth pipe 23 passes through the bracket 1 and is connected to the second pipe 22. A one-way valve 24 is provided on both the second pipe 22 and the fourth pipe 23. A round sleeve 8 is fixed to the bottom of the transparent protective cover 4. Multiple sets of teeth 9 are evenly fixed to the bottom of the inner cavity of the round sleeve 8. A drive motor 6 is fixed to the auxiliary seat 3 through the side frame. A gear 7 that meshes with the teeth 9 is fixed to the output shaft of the drive motor 6.

[0029] Specifically, this invention, by setting up auxiliary cleaning components, utilizes a water pump 20, along with a second pipe 22, a third pipe 18, an L-shaped nozzle 16, and multiple sets of nozzles 17 at different positions, to comprehensively clean the outer ring of the transparent protective cover 4 with water spray. Furthermore, in conjunction with a drive motor 6, gears 7, and teeth 9, the transparent protective cover 4 can be driven to rotate synchronously during water spraying, thereby simultaneously and quickly scraping away dirt from the outer ring of the transparent protective cover 4, enabling rapid and automatic cleaning. Simultaneously, the design of the air pump 21, along with a one-way valve 24, allows for air jet treatment of the surface after cleaning, quickly removing water stains from the surface of the transparent protective cover 4, further improving the cleaning effect. This multi-mode cleaning approach enables rapid and automatic cleaning of the surface of the transparent protective cover 4, effectively preventing dirt buildup from affecting the camera 5's accurate identification of road obstacles.

[0030] A protrusion is fixed on one side of the base frame 10, and the protrusion and the bottom bent end of the scraper 11 are hinged together by a hinge. A mounting frame 12 is fixed on the back side of one side of the base frame 10. An auxiliary motor 13 is fixed inside the mounting frame 12. A drive frame 14 is fixed to the output shaft of the auxiliary motor 13. An auxiliary slot 15 is provided on the scraper 11 for inserting one end of the drive frame 14. A placement slot is provided on the bracket 1 for the scraper 11, the third pipe 18 and the L-shaped nozzle 16 to be used together.

[0031] Specifically, the design of the auxiliary motor 13 can change the angle of the drive frame 14, and in conjunction with the auxiliary slot 15 and the hinge, the angle of the scraper 11 can be controlled so that when cleaning is not required, the scraper 11 and its components can be quickly flipped to the bottom to avoid obstructing the camera 5, thus improving the functionality of the device. In addition, the design of the placement slot provides sufficient space for the scraper 11 to swing, preventing the scraper 11 from colliding with the bracket 1 when it drives its components to rotate.

[0032] The vertical end of the third pipe 18 has a telescopic pipe structure, and the connection end between the third pipe 18 and the second pipe 22 has an L-shaped structure.

[0033] Specifically, the third pipe 18, with its vertical end designed as a telescopic tube structure, and its docking end designed as an L-shaped structure, allows the third pipe 18 to rotate with the scraper 11 without obstruction and without colliding with the bracket 1 and the base frame 10.

[0034] The end of the fourth pipe 23 near the second pipe 22 is inclined downward. The one-way valve 24 on the fourth pipe 23 is above the one-way valve 24 on the second pipe 22. The one-way valve 24 on the fourth pipe 23 is located at the bend end of the fourth pipe 23.

[0035] Specifically, the fourth pipe 23, with its downward-sloping structure at one end, and in conjunction with the one-way valve 24, can effectively prevent purified water from directly entering the air pump 21 through the fourth pipe 23, thereby preventing damage to the air pump 21, improving the stability of the device during operation, and avoiding mutual interference.

[0036] Multiple sets of arc-shaped drainage grooves are evenly distributed on the bottom of the disc 2.

[0037] Specifically, the design of multiple sets of arc-shaped drainage channels can quickly guide sewage and prevent sewage from accumulating on the disc 2, thus affecting the normal operation of the drive motor 6.

[0038] Both the placement frame 19 and the mounting frame 12 have an isolation net embedded at their bottom.

[0039] Specifically, the design of the isolation net can dissipate heat from the auxiliary motor 13, air pump 21 and water pump 20, preventing the auxiliary motor 13, air pump 21 and water pump 20 from overheating and being damaged in a relatively enclosed environment, thus improving the stability of the electrical equipment during operation.

[0040] The specific usage process is as follows: In the initial state, the scraper 11 is located inside the bracket 1 and below the transparent protective cover 4. At this time, the auxiliary motor 13 is turned on by the controller, which drives the drive frame 14 to rotate. With the cooperation of the auxiliary groove 15, the scraper 11 and its components can be driven to swing up quickly until one side of the scraper 11 is attached to the transparent protective cover 4. At this time, the water pump 20 and the drive motor 6 are turned on by the controller. The water pump 20 quickly transports the clean water in the water tank 25 to the L-shaped nozzle 16 through the second pipe 22 and the third pipe 18, and sprays it out in multiple directions onto the surface of the transparent protective cover 4 through the spray hole 17. At the same time, the drive motor 6 drives the gear 7 to rotate, which, with the assistance of the teeth 9, drives the circular sleeve 8 and the transparent protective cover 4 to rotate. The transparent protective cover 4 rotates synchronously, allowing for rapid and simultaneous scraping of dirt from its outer ring during water spraying. This enables quick and automatic cleaning of the outer ring of the transparent protective cover 4. After cleaning, to prevent water stains from adhering, the air pump 21 is activated via the controller. The air pump 21 rapidly delivers external air through the fourth pipe 23 to the second pipe 22 and the L-shaped nozzle 16, and then sprays it in multiple directions onto the surface of the transparent protective cover 4 through the nozzles 17. This, combined with the scraper 11, removes water stains, thus quickly cleaning the surface of the transparent protective cover 4. The one-way valve 24 controls the flow of clean water and air, allowing the air to quickly remove any remaining clean water from the second pipe 22, the third pipe 18, and the L-shaped nozzle 16. The rapid, automatic cleaning of the transparent protective cover 4 surface effectively prevents dirt buildup from affecting the camera 5's accurate obstacle recognition. This invention utilizes an auxiliary cleaning component, employing a water pump 20, along with a second pipe 22, a third pipe 18, an L-shaped nozzle 16, and multiple sets of nozzles 17 at different positions, to thoroughly clean the outer ring of the transparent protective cover 4 with water. Furthermore, the drive motor 6, gears 7, and teeth 9 drive the transparent protective cover 4 to rotate synchronously during water spraying, thus simultaneously and quickly scraping away dirt from the outer ring of the transparent protective cover 4. This allows for rapid, automatic cleaning of the outer ring of the transparent protective cover 4. Simultaneously, the design of the air pump 21, along with a one-way valve 24, allows for air jet treatment of the surface after cleaning. In order to quickly remove water stains from the surface of the transparent protective cover 4, the cleaning effect of the transparent protective cover 4 is further improved. At this time, multiple cleaning methods are used to quickly and automatically clean the surface of the transparent protective cover 4, thereby effectively preventing dirt from affecting the camera 5's accurate identification of road obstacles. The design of the auxiliary motor 13 can change the angle of the drive frame 14, and in conjunction with the auxiliary slot 15 and hinge, the angle of the scraper 11 can be controlled so that when cleaning is not required, the scraper 11 and its upper parts can be quickly flipped down to avoid obstructing the camera 5, thus improving the functionality of the device. The design of the placement slot provides sufficient space for the scraper 11 to swing, preventing the scraper 11 from colliding with the bracket 1 when it drives its upper parts to rotate.The third pipe 18, with its vertical end designed as a telescopic tube and its docking end designed as an L-shape, allows it to rotate unimpeded with the scraper 11 without colliding with the support 1 and the base frame 10. The fourth pipe 23, with one end sloping downwards and equipped with a one-way valve 24, effectively prevents clean water from directly entering the air pump 21 through the fourth pipe 23, thus avoiding damage to the air pump 21 and improving the stability of the device during operation, preventing mutual interference. The design of multiple sets of arc-shaped drainage channels allows for rapid drainage of sewage, preventing sewage accumulation on the disc 2 and affecting the normal operation of the drive motor 6. The design of the isolation net allows for heat dissipation of the auxiliary motor 13, air pump 21, and water pump 20, preventing overheating and damage to these components in a relatively enclosed environment, thus improving the stability of the electrical equipment during operation.

[0041] It should be noted that the functions to be implemented by each hardware component in this invention are supported by a large number of mature technologies and belong to the prior art. The essence of this invention is to optimize and combine existing hardware and its connection methods for specific application scenarios to meet the adaptation requirements of specific application scenarios and solve the problems raised in the background technology (without involving improvements to the internal software of the hardware).
