Description

Technical Field

[0001] This utility model belongs to the field of remote control vehicles, specifically, it relates to an intelligent remote control vehicle with anti-collision function. Background Technology

[0002] With the development of electronic information technology and intelligent control technology, intelligent remote control cars have been widely used in fields such as toys and entertainment, education and scientific research, and environmental detection. They achieve remote operation through wireless remote control technology and have gradually integrated intelligent functions such as autonomous navigation, path planning, and environmental perception, which greatly improves the ease of use and scene adaptability. However, when existing intelligent remote control cars are operated by children, the front of the toy cars is very easy to collide with the corners of walls, doors, tables and chairs, which can easily damage the body parts and cause malfunctions.

[0003] Chinese patent CN218165956U discloses an intelligent toy remote control car with anti-collision function. The device uses an inflatable airbag to slow down and buffer the car body, making the front parts less prone to damage and improving the safety performance of the car body. However, during use, the user needs to judge the position of the remote control car in real time. When the remote control car is far away from the user, the user cannot clearly see the surrounding environment, which reduces the control of the remote control car. At the same time, the remote control car of this device does not have an obstacle avoidance function, making the remote control car prone to collisions during driving, which will eventually damage the remote control car.

[0004] In view of this, this utility model is proposed. Utility Model Content

Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings.

[0019] Please see Figure 1-11 As shown, this embodiment provides an intelligent remote control car with anti-collision function, including a base plate 1, a shell 2, a control module 11, two front wheels 3, two rear wheels 6, and a first motor 10 for driving the two rear wheels 6 to rotate. It also includes a mounting cover 5, which is disposed on the shell 2. The mounting cover 5 has a recessed mounting groove 22. An infrared sensor 20 and a camera 21, which are signal-connected to the control module 11, are fixedly installed in the mounting groove 22. The infrared sensor 20 and the camera 21 are both arranged facing the front end of the shell 2. Two sets of rotating frames 12 are rotatably disposed on both sides of the base plate 1 through a first rotating shaft 13. The two front wheels 3 are respectively rotatably disposed on the two sets of rotating frames 12. The base plate 1 is provided with a steering assembly 7 for driving the two front wheels 3 to turn. The steering assembly 7 is signal-connected to the control module 11.

[0020] Specifically, in this embodiment, the outer shell 2 is fixedly mounted on the base plate 1. Two sets of front wheels 3 and two sets of rear wheels 6 are rotatably mounted on both sides of the base plate 1. The control module 11 controls the first motor 10, the steering assembly 7, the infrared sensor 20, and the camera 21. A wireless module is also installed on the floor to transmit the video captured by the camera 21 to the user's controller, allowing the user to observe the surroundings of the remote-controlled car in real time. After the intelligent remote-controlled car is started, the control module 11 initializes each component (first motor 10, steering assembly 7, infrared sensor 20, camera 21, wireless module) to ensure that each component is in a ready-to-work state. The infrared sensor 20 continuously emits infrared signals forward. When it encounters an obstacle, the signal is reflected and received. The sensor transmits the obstacle distance information to the control module 11 in real time. The camera 21 simultaneously captures images of the environment ahead. After processing by the control module 11, the video signal is transmitted to the user's controller by the wireless module, allowing the user to observe the surroundings in real time. The user sends driving commands (forward, backward, ...) through the controller. Commands (such as steering) are transmitted wirelessly to the control module 11. The control module 11 controls the first motor 10 to operate, driving the two rear wheels 6 to rotate, enabling the vehicle to move forward or backward. If steering is required, the control module 11 activates the steering assembly 7, driving the two sets of rotating frames 12 to rotate around the first rotating shaft 13, causing the two front wheels 3 to deflect, thus completing the steering action. When the infrared sensor 20 detects that the distance to an obstacle ahead is less than the safety threshold, the information is fed back to the control module 11. After confirming the obstacle information by combining the image from the camera 21, the control module 11 automatically adjusts the first motor 10 (such as deceleration or stopping) and the steering assembly 7 (such as steering to avoid collisions). At the same time, the user can manually correct the driving direction by using real-time video assistance. The overall mechanism is simple to operate. The infrared sensor 20 quickly detects obstacles at close range, and the camera 21 provides visual environmental information. The combination of the two enables the control module 11 to more accurately determine the position, distance, and shape of obstacles, improving obstacle avoidance accuracy and preventing damage to the remote control car after prolonged use.

[0021] It should be noted that, in this embodiment, the working principle of the control module 11, the infrared sensor 20, and the camera 21 is existing technology and will not be described here.

[0022] In this embodiment, as Figures 1 to 7As shown, the steering assembly 7 includes a second motor 71, a rotating plate 72, and two drive arms 73. The second motor 71 is fixedly mounted on the base plate 1. The rotating plate 72 is centrally fitted and fixedly mounted on the drive shaft of the second motor 71. The first ends of the two sets of drive arms 73 are respectively hinged to both ends of the rotating plate 72, and the second ends of the two sets of drive arms 73 are respectively hinged to two sets of rotating frames 12. The second motor 71 is signal-connected to the control module 11. A protective cylinder 14 is fixedly mounted on the base plate 1 and the outer shell 2. The mounting cover 5 is slidably disposed inside the protective cylinder 14. The protective cylinder 14 is provided with a storage groove 19 for the mounting cover 5 to slide. The protective cylinder 14 is provided with a protective component 8 for driving the mounting cover 5 to slide. Specifically, the protective cylinder 14 is fixedly mounted on the base plate 1 and the outer shell 2. On the shell 2, the protective cylinder 14 extends to the outside of the shell 2 from the end opposite to the bottom plate 1. When the control module 11 issues a steering command, the second motor 71 starts, and its drive shaft drives the rotating plate 72 to rotate. When the rotating plate 72 rotates, it drives the two sets of rotating frames 12 to rotate around the first rotating shaft 13 through the two drive arms 73, thereby realizing the steering of the front wheel 3. At the same time, when the remote control car encounters a possible collision, the protective component 8 will drive the mounting cover 5 to slide in the storage slot 19 of the protective cylinder 14 to store the infrared sensor 20 and the camera 21, which plays a protective role. The setting of the protective cylinder 14 and the protective component 8 can protect the key sensor components when the remote control car is in a collision, reduce the possibility of damage, and improve the durability of the remote control car.

[0023] In this embodiment, as Figures 1 to 8 As shown, a collision avoidance assembly 4 is provided on the base plate 1. The collision avoidance assembly 4 includes a fixed block 45, which is fixedly installed on the base plate 1. A movable plate 43 is movably installed inside the fixed block 45. A movable groove 16 is provided inside the fixed block 45 for the movable plate 43 to move. A spring 44 is provided inside the movable groove 16 to abut against the movable plate 43. A first rack 42 is fixedly connected to the movable plate 43 at one end and extends to the outside of the base plate 1 and the outer shell 2 at the other end, where an arc-shaped plate 41 is fixedly installed. The first rack 42 is movably installed inside the fixed block 45. Specifically, the first rack 42 passes through and is movably installed on the outer shell 2. The spring 44 in the collision avoidance assembly 4 plays a buffering role, which can absorb the energy during the collision and reduce the impact force on the remote control car body, thereby protecting the internal structure and electronic components of the remote control car from damage. The arc-shaped plate 41 can increase the contact area with the obstacle, making the collision force distribution more uniform and further reducing the impact of the collision.

[0024] In this embodiment, as Figures 1 to 8As shown, the protective component 8 includes a second rack 83 and two gears 81. The two gears 81 are rotatably mounted on the fixed block 45 via a second rotating shaft 82. The first end of the second rack 83 is fixedly connected to the mounting cover 5. The second rack 83 passes through and is movably mounted on the protective cylinder 14. The two gears 81 mesh with the first rack 42 and the second rack 83, respectively. Specifically, when the first rack 42 moves due to a collision, the movement of the first rack 42 will drive the second rack 83 to move through the gears 81. The second rack 83 is fixedly connected to the mounting cover 5, thereby causing the mounting cover 5 to slide inside the protective cylinder 14, thus protecting the sensor inside the mounting cover 5. Through the transmission structure of the gears 81 and rack, the action of the anti-collision component 4 is linked with the action of the protective component 8, so that the sensor can be automatically and promptly protected when the remote control car collides, without the need for additional control circuits or complex operations. The structure is simple and highly reliable.

[0025] In this embodiment, as Figures 6 to 11As shown, the fixed block 45 is provided with a limiting component 9 for limiting the movable plate 43. The limiting component 9 includes two mounting plates 96, which are symmetrically fixedly mounted on the fixed block 45, and a rotating rod 91, which is rotatably disposed between the two mounting plates 96 via a third rotating shaft 97. A torsion spring 92 is sleeved on the rotating rod 91, and the two ends of the torsion spring 92 are fixedly connected to the mounting plate 96 and the rotating rod 91, respectively. A limiting block 93 and a sliding block 94 are fixedly mounted on the rotating rod 91, which are relative to the limiting block 93. 3. Fixedly mounted on the movable plate 43, the sliding block 94 is slidably disposed within the fixed block 45, the sliding block 94 has an embedded limit groove 95, and the fixed block 45 has a through hole 23 communicating with the movable groove 16. A connecting rod 15 is vertically fixedly connected to the drive shaft of the second motor 71, and an abutment plate 17 is fixedly mounted on the end of the connecting rod 15 away from the second motor 71. The abutment plate 17 intermittently abuts against the end of the rotating rod 91 away from the limit block 93. Specifically, under normal conditions, the torsion... Spring 92 causes the limiting block 93 on the rotating rod 91 to engage in the through hole 23. When the first rack 42 moves under the impact force, the movable plate 43 drives the sliding block 94 to move into the movable groove 16. The movable plate 43 compresses the spring 44. When the sliding block 94 slides to the through hole 23, the sliding block 94 pushes the limiting block 93 to move. The limiting block 93 pushes the rotating rod 91 to rotate, thereby causing the limiting block 93 to engage in the limiting groove 95 to limit the movable plate 43. When it is necessary to release the limiting block 93, the limiting block 93 can be engaged in the limiting groove 95. When the limit is reached at position 3, the user can control the second motor 71 to rotate via the controller. The connecting rod 15 rotates together with the drive shaft of the second motor 71. The contact plate 17 on the connecting rod 15 intermittently contacts the end of the rotating rod 91 away from the limit block 93. When the contact plate 17 contacts the rotating rod 91, it pushes the rotating rod 91 to rotate, causing the limit block 93 to disengage from the limit groove 95 of the sliding block 94, thereby releasing the limit on the movable plate 43. The movable plate 43 is reset under the action of the spring 44.

[0026] In this embodiment, as Figures 6 to 10 As shown, a limiting plate 18 is fixedly installed on the mounting cover 5, and the limiting plate 18 is slidably disposed in the storage groove 19.

[0027] Working principle: When the remote-controlled car is in use, the infrared sensor 20 and camera 21 start working. The infrared sensor 20 continuously emits infrared signals forward and receives reflected signals, while the camera 21 captures real-time images of the environment ahead. Both transmit the data synchronously to the control module 11. The limiting component 9 is in its initial state and does not limit the movable plate 43. The arc plate 41 is in its initial position, i.e., at the front end of the base plate 1 and the outer shell 2. The mounting cover 5 is located outside the protective cylinder 14 and on the top of the outer shell 2. The infrared sensor 20 and camera 21 are fully exposed to obtain the maximum detection range. The limiting plate 18 is in its initial position within the storage slot 19, preventing the mounting cover 5 from sliding out of the protective cylinder 14. The control module 11 receives the distance data from the infrared sensor 20 and the image data from the camera 21. It analyzes the presence of obstacles ahead and their distance, size, and position using algorithms. If an obstacle is detected and is far away (e.g., >1 meter), the control module 11 transmits obstacle information to the remote control via wireless signal (to assist the user in judgment). At the same time, it calculates the turning angle based on the obstacle's position. If an obstacle is detected and is close (e.g., <0.5 meters), the control module 11 transmits the obstacle information to the remote control via wireless signal.(1 meter), the control module 11 automatically triggers the obstacle avoidance command without manual operation by the user. At this time, the two sets of second motors 71 of the control module 11 start, and their drive shafts drive the rotating plate 72 to rotate. The rotating plate 72 pulls the rotating frame 12 on both sides to rotate around the first rotating shaft 13 through the drive arms 73 hinged at both ends, thereby driving the two front wheels 3 to turn synchronously, so that the remote control car can avoid obstacles to the left / right. If the obstacle avoidance is not timely and a collision occurs, the obstacle hits the arc plate 41. The arc plate 41 pushes the first rack 42 to move into the fixed block 45. The first rack 42 drives the movable plate 43 to compress the spring in the movable groove 16. Spring 44 deforms to absorb collision energy, reducing the impact on the vehicle body. Simultaneously, when the first rack 42 moves, the gear 81 meshing with it rotates, driving another gear 81 and the meshing second rack 83 to move. The second rack 83 pulls the mounting cover 5 inward along the storage groove 19 of the protective cylinder 14, pulling the infrared sensor 20 and camera 21 into the protective cylinder 14 (preventing the sensors from directly impacting obstacles). When the sliding block 94 moves with the movable plate 43, when the movable plate 43 moves to the designated position in the movable groove 16, the limiting groove 95 on the sliding block 94 corresponds to the limiting block 93, causing the limiting block... Inserting 93 into the limiting groove 95 limits the movable plate 43, preventing the mounting cover 5 from detaching from the protective cylinder 14. When it is necessary to remove the mounting cover 5 along the protective cylinder 14, the steering assembly 7 can be rotated by an external controller. That is, the connecting rod 15 on the drive shaft of the second motor 71 rotates with the drive shaft, causing the contact plate 17 to intermittently contact the rotating rod 91. The rotating rod 91 overcomes the elastic force of the torsion spring 92 and rotates around the third rotating shaft 97, causing the limiting block 93 to disengage from the limiting groove 95 of the sliding block 94, releasing the limitation on the movable plate 43. This allows the movable plate 43 to reset under the action of the spring 44, thus obtaining the arc plate 41. The system is reset for subsequent use. Simultaneously, the first rack 42 moves in the reverse direction, driving the second rack 83 to move in the reverse direction via gear 81. The mounting cover 5 slides out of the protective cylinder 14, re-exposing the sensor for continued detection. The overall structure features simple operation and a high degree of automation. The infrared sensor 20 and camera 21 enable long-distance environmental detection, assisting the user in judgment. The control module 11 automatically triggers obstacle avoidance steering (reducing reliance on manual operation). The anti-collision component 4 and the protective component 8 work together to achieve collision buffering and sensor protection (reducing the risk of damage), comprehensively solving the problems of low long-distance operability and susceptibility to collision damage.

Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model.
