Description

Technical Field

[0001] This invention belongs to the field of tracking vehicle technology, specifically relating to a high-speed intelligent tracking vehicle. Background Technology

[0002] In general vehicle testing experiments, a track with barriers is used, with identifiable markings on the track floor. The test vehicle identifies and moves along the markings. However, when testing the vehicle's high-speed recognition capability and turning performance, the vehicle is prone to deviating from the original track at high speeds, making it easy for the vehicle to collide with the barriers. The barriers are usually made of rubber cushioning material, but as the test speed increases and the angle of the curve increases, the vehicle may still be damaged after colliding with the barriers. Since the vehicle's base plate is a single piece, disassembling and replacing all components when damaged is very troublesome. Summary of the Invention

[0003] The purpose of this invention is to provide a simple and rationally designed high-speed intelligent vehicle that follows tracks in order to solve the above problems.

[0004] The present invention achieves the above objectives through the following technical solutions:

[0005] A high-speed intelligent vehicle with tracking capability includes a base plate, front wheels, and rear wheels. Two sets of front and rear wheels are provided on each side of the base plate. The vehicle is characterized by further including a control component and a detection component. The detection component is located on the side of the base plate near the front of the vehicle. The control component is electrically connected to the detection component and the servo motor of the front wheels. The detection component transmits signals to the control component, which can control the servo motor of the front wheels to adjust its direction. The base plate includes a detachably connected main plate and a protective plate. The protective plate is positioned in the direction of movement of the main plate and is an elastic element. When the protective plate is compressed to its limit, the main plate and the protective plate separate.

[0006] As a further optimization of the present invention, a cylindrical body is fixedly connected to the surface of the protective plate, and a limiting member is slidably connected inside the cylindrical body. Two sets of limiting members are provided, and a limiting groove adapted to the limiting member is opened inside the main board. The limiting member can be inserted into or removed from the limiting groove.

[0007] As a further optimization of the present invention, the protective plate includes an airbag, the airbag is connected to a connecting pipe, the connecting pipe is connected to the cylinder, and the connection point is between the limiting member and the cylinder. When the airbag is compressed, the gas in the airbag enters between the limiting member and the cylinder through the connecting pipe, driving the limiting member to move out of the limiting groove. At this time, the main board and the protective plate are separated.

[0008] As a further optimization of the present invention, a piston plate is fixedly connected to the end of the limiting member, and a first-order return member is provided between the two sets of piston plates.

[0009] As a further optimization of the present invention, air inlets are provided on both sides of the cylinder, and a U-shaped pipe is connected between the two sets of air inlets, and the connecting pipe is connected to the U-shaped pipe.

[0010] As a further optimization of the present invention, the airbag is provided in several groups, and the several groups of airbags are evenly distributed on the surface of the protective plate. The airbags are all connected to the U-shaped tube through the connecting pipe. When the airbag is compressed, the gas is transported to both sides of the cylinder through the connecting pipe and the U-shaped tube, so that the two groups of piston plates move closer to each other, thereby driving the two groups of limiting members to move out of the limiting groove.

[0011] As a further optimization of the present invention, each airbag surface is provided with an auxiliary plate, and a foam support plate, a third recovery component, and a folding frame assembly are provided between the auxiliary plate and the protective plate. When the foam support plate is supported between the auxiliary plate and the protective plate, the third recovery component is in a stored state. When it is impacted, the folding frame assembly deforms and destroys the foam support plate, thereby moving the third recovery component and fully compressing the airbag.

[0012] As a further optimization of the present invention, the detection component can rotate at the end of the motherboard. When the detection component rotates past the front wheel, the detection component is in a detection state. When the detection component rotates to the bottom of the motherboard, the detection component can be protected.

[0013] As a further optimization of the present invention, the detection component includes probes disposed on both sides of the lower surface of the motherboard. A movable plate is slidably connected inside the limiting groove, and a second return component is disposed between the movable plate and the limiting groove. A toothed plate is disposed on the surface of the movable plate. The probe is rotatably connected to the motherboard, and a gear meshing with the toothed plate is fixedly connected to the surface of the probe. When the limiting component moves out of the limiting groove, the second return component drives the movable plate and the toothed plate to move back, and the gear meshing with the toothed plate rotates, so that the probe rotates completely to the bottom of the motherboard.

[0014] As a further optimization of the present invention, a connecting rope is provided between the motherboard and the protective plate. When the limiting member moves out of the limiting groove, the protective plate falls to the ground under its own weight. The connecting rope can keep the protective plate connected to the motherboard when it is on the ground.

[0015] The beneficial effects of this invention are as follows: This invention can effectively protect the electrical components in intelligent vehicles, and it features a detachable protective plate and main board, which facilitates flexible replacement of damaged components.

[0026] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0027] refer to Figure 1The structure shown provides a tracking high-speed mobile intelligent vehicle, including a base plate 1, front wheels 2, and rear wheels 3. Two sets of each of the front wheels 2 and rear wheels 3 are provided on both sides of the base plate 1. The vehicle also includes a control component 4 and a detection component. The detection component is located on the side of the base plate 1 near the front of the vehicle, and the control component 4 is electrically connected to the detection component and the servo motor of the front wheel 2. The detection component transmits signals to the control component 4, which can control the servo motor of the front wheel 2 to adjust its direction. The base plate 1 includes a detachably connected main plate 11 and a protective plate 12. The protective plate 12 is located in the direction of movement of the main plate 11 and is an elastic element. When the protective plate 12 is compressed to its limit, the main plate 11 and the protective plate 12 separate.

[0028] In this embodiment, it should be noted that the solution uses the STC89C52 microcontroller as the main controller. The car motor is equipped with a reduction gear set. The DC motor is controlled by a motor drive chip. By changing the input level of the chip control terminal, the motor can be rotated forward and backward and stopped, which can also meet the requirements of the DC geared motor.

[0029] Specifically, in this embodiment, the intelligent vehicle mainly consists of: a guide line serving as the target for the vehicle to track; a detection system detecting the vehicle's relative path; inputting this information into a microcontroller; the microcontroller processing this information; and outputting control commands to the drive module to control the vehicle's DC motor, ensuring the vehicle travels quickly and smoothly along a pre-set route. A 5V rechargeable battery pack is used as the main power source. An STC89C52 microcontroller serves as the main controller. Because the vehicle's motor contains a reduction gear set, speed regulation is not required. A motor driver chip controls the DC motor; by changing the input level of the chip's control terminal, the motor can be rotated forward, reversed, or stopped, meeting the requirements of a DC geared motor. Using this chip as the motor driver offers advantages such as ease of operation and good stability. A photodetector is constructed using photoresistors. The resistance of the photoresistor changes with the ambient light. When light shines on a white line, the light emission is strong; when light shines on a black line, the light emission is weak. Thus, the microcontroller and the tracking sensor form a system with feedback signals.

[0030] In other embodiments, the following components are used: one STM microcontroller; two infrared sensors; one battery; two DC geared motors; one DC stepper motor driver board; one switch; and DuPont wires. The positive terminal of the power supply is connected to the 12V driver power supply, and the negative terminal is connected in series with the switch to the driver power supply GND. The driver's OUT1, OUT2, OUT3, and OUT4 pins are connected to the motors via DuPont wires. The STM microcontroller's A1, A2, A3, and A4 pins are connected to the driver's N1, N2, N3, and N4 pins via DuPont wires, respectively. The OUT pins of the two infrared sensors are connected to the STM microcontroller's B12 and B13 pins via DuPont wires, the infrared sensor's GND pin is connected to the STM microcontroller's GND pin via DuPont wires, and the infrared sensor's VCC pin is connected to the STM microcontroller's 3.3 pin via DuPont wires. The battery module provides power. For the infrared sensors: when a black line is detected, the green indicator light on the circuit board illuminates, and the OUT port continuously outputs a low-level signal. IN1, IN2, IN3, and IN4 are used to control the forward, reverse, and stop rotation of the two motors by their voltage levels. The STM microcontroller module receives signals from the sensors and commands from the PC; it analyzes and processes the collected signals and sends them to various modules that require control.

[0031] The power supply provides power to the entire system. The infrared sensor detects the black line signal and outputs it to the STM microcontroller. The STM microcontroller receives the signal from the infrared sensor, processes it, and sends it to the drive module. The drive module adjusts the motor's voltage level to change the motor's direction of rotation.

[0032] Further reference Figures 2 to 4 As shown in the structure, a cylindrical body 74 is fixedly connected to the surface of the protective plate 12. A limiting member 61 is slidably connected inside the cylindrical body 74. Two sets of limiting members 61 are provided. A limiting groove 62 adapted to the limiting member 61 is opened inside the main plate 11. The limiting member 61 can be inserted into or removed from the limiting groove 62.

[0033] Furthermore, the protective plate 12 includes an airbag 71, which is connected to a connecting pipe 72. The connecting pipe 72 is connected to the cylinder 74, and the connection point is between the limiting member 61 and the cylinder 74. When the airbag 71 is compressed, the gas in the airbag 71 enters between the limiting member 61 and the cylinder 74 through the connecting pipe 72, driving the limiting member 61 to move out of the limiting groove 62. At this time, the main board 11 separates from the protective plate 12.

[0034] Furthermore, a piston plate 76 is fixedly connected to the end of the limiting member 61, and a first return member 75 is provided between the two sets of piston plates 76; air inlets are provided on both sides of the cylinder 74, and a U-shaped tube 73 is connected between the two sets of air inlets, and the connecting pipe 72 is connected to the U-shaped tube 73; several sets of airbags 71 are provided, and the several sets of airbags 71 are evenly distributed on the surface of the protective plate 12. Each airbag 71 is connected to the U-shaped tube 73 through the connecting pipe 72. When the airbag 71 is compressed, the gas is transported to both sides of the cylinder 74 through the connecting pipe 72 and the U-shaped tube 73, so that the two sets of piston plates 76 move closer to each other, thereby driving the two sets of limiting members 61 to move out of the limiting groove 62.

[0035] Based on Example 1, further, referring to Figures 5 to 9 As shown in the diagram, it should be noted that in the actual setup, each airbag 71 has an auxiliary plate 91 on its surface. A foam support plate 92, a third recovery component 94, and a folding frame assembly 93 (optional) are provided between the auxiliary plate 91 and the protective plate 12. When the folding frame assembly 93 is in place, the foam support plate 92 is supported between the auxiliary plate 91 and the protective plate 12, and the third recovery component 94 is in a stored state. Upon impact, the folding frame assembly 93 deforms, which breaks the foam support plate 92, and the third recovery component 94 moves, fully compressing the airbag 71.

[0036] It should also be noted that the foam support plate 92 can help protect the main board 11 after the base plate 1 is impacted.

[0037] Furthermore, the detection component can rotate at the end of the motherboard 11. When the detection component rotates past the front wheel 2, the detection component is in a detection state. When the detection component rotates to below the motherboard 11, the detection component can be protected.

[0038] Furthermore, the detection assembly includes probes 5 disposed on both sides of the lower surface of the motherboard 11. A movable plate 81 is slidably connected inside the limiting groove 62, and a second return member 82 is disposed between the movable plate 81 and the limiting groove 62. A toothed plate 83 is disposed on the surface of the movable plate 81. The probes 5 are rotatably connected to the motherboard 11, and a gear 84 that meshes with the toothed plate 83 is fixedly connected to the surface of the probes 5. When the limiting member 61 moves out of the limiting groove 62, the second return member 82 drives the movable plate 81 and the toothed plate 83 to move back, and the gear 84 that meshes with the toothed plate 83 rotates, so that the probes 5 rotate completely below the motherboard 11.

[0039] A connecting rope 10 is provided between the main board 11 and the protective plate 12. When the limiting member 61 moves out of the limiting groove 62, the protective plate 12 falls to the ground under its own weight. The connecting rope 10 keeps the protective plate 12 connected to the main board 11 when it is on the ground. In actual use, a corresponding resistance mechanism can be provided on the lower surface of the protective plate 12, such as a rubber pad. When the vehicle body is impacted, the main board 11 and the protective plate 12 separate. The connecting rope 10 keeps the main board 11 connected to the protective plate 12. The connection between the two is maintained. After the vehicle body is impacted, it will move in the opposite direction due to the reaction force. At this time, the protective plate 12 is connected to the ground through the connecting rope 10 and the main board 11 and moves relative to the ground. The resistance mechanism at the bottom of the protective plate 12 can reduce the movement speed of the vehicle body when it rebounds, so that the vehicle body stops in a short time. In actual use, a corresponding reinforcing rib structure can be added inside the protective plate 12. On the one hand, it can improve the strength of the protective plate 12, and on the other hand, it can increase the weight of the protective plate 12 and increase the friction between the protective plate 12 and the ground.

[0040] Furthermore, both ends of the connecting rope 10 are connected to the main board 11 and the protective plate 12 by means of a locking buckle. In actual use, when the protective plate 12 is severely damaged, the connection between the main board 11 and the protective plate 12 can be released by the locking buckle and a new protective plate 12 can be replaced.

[0041] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
