Description
Technical Field
[0001] This utility model relates to the field of toy equipment technology, and in particular to a novel remote-controlled electric vehicle. Background Technology
[0002] Remote-controlled electric toy cars are toy cars that are remotely controlled via radio remote control. They fall under the category of remote-controlled model cars (RC cars). Their core feature is the use of radio remote control technology to control the toy car's forward, backward, and turning movements. Operating remote-controlled electric toy cars can help children develop hand-eye coordination, logical thinking, and problem-solving skills. It can also cultivate their concentration and decision-making abilities. Some models even incorporate traffic rule education functions, helping children establish safety awareness.
[0003] While existing remote-controlled electric toy cars have their advantages, they also suffer from several technical drawbacks due to structural limitations. Firstly, they lack safety features when moving forward or backward. If the toy car encounters obstacles such as walls at the front or rear, or if wireless control is delayed, there is a risk of damage. Secondly, since forward and backward movement is only controlled wirelessly, children have relatively limited knowledge of the technology and cannot broaden their understanding. Therefore, it is essential to provide an electric toy car that offers better self-protection and enhances children's knowledge. Utility Model Content
[0004] To overcome the shortcomings of existing remote-controlled electric toy cars, which are limited by their structure and have the drawbacks described in the background art, this utility model provides a new type of remote-controlled electric car based on a remote-controlled electric toy car body. In application, under the joint action of related mechanisms, children can control the toy car body to move forward, backward, and turn not only wirelessly but also through light control. Moreover, the motor power of the toy car body can be disconnected in time before the toy car body moves forward or backward at a certain distance from an obstacle (such as a wall), thereby playing a better self-protection role and improving children's knowledge of light control.
[0005] The technical solution adopted by this utility model to solve its technical problem is:
[0006] A novel remote-controlled electric vehicle includes a remote-controlled electric toy car body, an infrared emitting module, an infrared receiving module, a wireless emitting module, a wireless receiving circuit, a photoelectric detection module, and a convex lens. Multiple sets of the convex lens and infrared receiving module are included, and at least two sets of the photoelectric detection module and infrared emitting module are included.

The front and rear ends of the toy car body each have mounting holes, and multiple sets of infrared receiving modules are fixedly installed within these mounting holes. Multiple sets of convex lenses are fixedly installed within the front ends of these mounting holes. The infrared emitting module and wireless emitting module are installed inside a component box. The emitting head of the infrared emitting module is located outside an opening at the front end of the component box, and the transmitting button of the wireless emitting module is located outside the upper end of the component box. The wireless receiving circuit is installed inside the electric toy car body, and its control signal input terminal is electrically connected to the signal output terminals of the photoelectric detection module and the multiple sets of infrared receiving modules.
[0007] Furthermore, the front photoelectric detection module of the toy car body has its probe facing forward, the rear photoelectric detection module has its probe facing backward, the front infrared receiving module has its receiving surface facing forward, and the rear infrared receiving module has its receiving surface facing backward.
[0008] Furthermore, the distance between the transmitter heads of the two infrared emitting modules is the same as the distance between the two sets of double-sided convex lenses at the front and rear ends of the toy car body.
[0009] Furthermore, the photoelectric receiver head of the infrared receiving module is located at the focal point of the rear end of the convex lens.
[0010] Furthermore, the wireless receiving circuit includes electrically connected relays and a wireless receiving circuit module. The four power output terminals of the wireless receiving circuit module are respectively connected to the positive power input terminals of the four relays. The positive control power input terminals of the first and second relays are connected, as are the positive control power input terminals of the third and fourth relays. The negative power input terminals and negative control power input terminals of the four relays are connected to the negative power input terminal of the wireless receiving circuit module.
[0011] Furthermore, the multiple sets of infrared receiving modules are equipped with four electrically connected relays. The negative power input terminals of the four relays are connected to the negative power input terminals of the multiple sets of infrared receiving modules. The positive power input terminal and positive control power input terminal of the first relay are connected to the power output terminal of the first set of infrared receiving modules. The positive power input terminal and positive control power input terminal of the second relay are connected to the power output terminal of the second set of infrared receiving modules. The positive power input terminal and positive control power input terminal of the third relay are connected to the power output terminal of the third set of infrared receiving modules. The positive power input terminal and positive control power input terminal of the fourth relay are connected to the power output terminal of the fourth set of infrared receiving modules. The positive power input terminals of the multiple sets of infrared receiving modules are also connected.
[0012] Compared with the prior art, the beneficial effects of this utility model are: This utility model is based on a remote-controlled electric toy car body. In application, under the joint action of related mechanisms, children can not only wirelessly control the toy car body to move forward or backward and turn through the wireless transmitting module and wireless receiving circuit, but also...
[0013] It can also control the toy car to move forward, backward, and turn through four sets of infrared receiving modules and infrared transmitting modules via light control. When the toy car moves forward or backward at a certain distance from an obstacle (such as a wall), the power supply to the motor of the toy car can be cut off in time under the action of photoelectric modules, which can prevent the toy car from being damaged. This can play a better role in protecting the toy car itself and enhance children's knowledge of light control. Attached Figure Description

The front infrared receiving modules E4 and E5 have their receiving surfaces facing forward, and the rear infrared receiving modules E6 and E7 have their receiving surfaces facing backward. The photoelectric detector heads of the four sets of infrared receiving modules E4, E5, E6, and E7 are located at the focal points of the rear ends of the four sets of double-sided convex lenses 5. The distance between the emitters of the two sets of infrared emitting modules 2 is the same as the distance between the two sets of double-sided convex lenses 5 at the front and rear ends of the toy car body. The wireless receiving circuit includes four relays J1, J2, J3, and J4 connected via circuit board wiring, a wireless receiving circuit module E1, and four power output terminals (pins 3, 4, 5, and 6) of the wireless receiving circuit module E1 connected to the positive power input terminals of the four relays J1, J2, J3, and J4 respectively. The positive control power input terminals of the first relay J1 and the second relay J2 are connected, as are the positive control power input terminals of the third relay J3 and the fourth relay J4. The negative power input terminals and negative control power input terminals of the four relays J1, J2, J3, and J4 are connected to the negative power input terminal (pin 2) of the wireless receiving circuit module E1. Four infrared receiver modules E4, E5, E6, and E7 are equipped with four relays J5, J6, J7, and J8 mounted on a circuit board and connected via circuit board wiring. The negative power input terminals of the four relays J5, J6, J7, and J8 are connected to pin 2 of the negative power input terminals of the four infrared receiver modules E4, E5, E6, and E7. The positive power input terminal and positive control power input terminal of the first relay J5 are connected to pin 3 of the power output terminal of the first infrared receiver module E4. The second relay J6... The positive power input terminal and the positive control power input terminal are connected to pin 3 of the power output terminal of the second infrared receiving module E5. The positive power input terminal and the positive control power input terminal of the third relay J7 are connected to pin 3 of the power output terminal of the third infrared receiving module E6. The positive power input terminal and the positive control power input terminal of the fourth relay J8 are connected to pin 3 of the power output terminal of the fourth infrared receiving module E7. Pin 1 of the positive power input terminals of the four infrared receiving modules E4, E5, E6, and E7 is connected. The power input terminals 1 and 2 of the wireless receiving circuit module E1, the power input terminals 1 and 2 of the two photoelectric detection modules E2 and E3, the power input terminals 1 and 2 of the four infrared receiving modules E5, E6, E7, and E8, and the two poles of the battery G1 inside the electric toy car are connected by wires respectively; the positive control power input terminals of relays J1 and J2 are connected by wires to the power output terminal 3 of the photoelectric detection module E2, and the positive control power input terminals of relays J3 and J4 are connected by wires to the power output terminal 3 of the photoelectric detection module E3; the normally open contacts of relays J5, J6, J7, and J8 are connected by wires to the positive power input terminals of relays J1, J2, J3, and J4 respectively.The power input terminals 1 and 2 of the infrared transmitting module 2 (whose power switch is located outside the opening at the upper rear of the component box) and the two terminals of a 12V battery 7 (connected in parallel to the two terminals of a charging socket 8 via wires; when the battery 7 is depleted, the external 12V power charger is inserted into the charging socket 8 to charge the battery) are connected via wires. The two normally open contacts of relay J1 and relay J2 are connected via wires to the positive and negative power input terminals of the motors of the two electric drive wheels at the front and rear of the left end and the two electric drive wheels at the front and rear of the right end of the toy car body 1, respectively. The two normally open contacts of relay J3 and relay J4 are connected via wires to the positive and negative power input terminals of the motors of the two electric drive wheels at the front and rear of the left end and the two electric drive wheels at the front and rear of the right end of the toy car body 1, respectively.
[0020] Figure 1 , 2As shown in Figure 3, the 12V DC power output from battery G1 enters the power input terminals of the wireless receiving circuit, photoelectric detection modules E2 and E3, and infrared receiving modules E4, E5, E6, and E7, thus powering up the aforementioned circuits and modules. When the user presses the first and second transmit buttons of the wireless transmitting module 3, the wireless transmitting module 3 transmits the first and second wireless closed signals. After receiving these signals, the wireless receiving circuit module E1 outputs high-level signals from pins 3 and 4, respectively, which enter the power input terminals of relays J1 and J2. Relays J1 and J2 are energized and their control power input terminals and normally open contacts close. Consequently, the positive and negative power input terminals of the motors of the two electric drive wheels at the front and rear of the left end and the two electric drive wheels at the front and rear of the right end of the toy car body 1 are energized, causing the toy car body 1 to move forward in a straight line. When the user presses the first and second transmit buttons of the wireless transmitter module 3 again, the wireless transmitter module 3 transmits the first and second open-circuit wireless signals. Upon receiving these signals, the wireless receiver module E1 stops outputting high-level signals at pins 3 and 4, which then enter the power input terminals of relays J1 and J2. Relays J1 and J2 are de-energized and their control power input terminals and normally open contacts are no longer closed, thus stopping the toy car body 1 from moving forward in a straight line. When the user presses the third and fourth transmit buttons of the wireless transmitter module 3, the wireless transmitter module 3 transmits the third and fourth closed-circuit wireless signals. Upon receiving these signals, the wireless receiver module E1 outputs high-level signals at pins 5 and 6, respectively, which then enter the power input terminals of relays J3 and J4. Relays J3 and J4 are energized and their control power input terminals and normally open contacts are closed. This energizes the positive and negative power input terminals of the motors for the two electric drive wheels on the left and right sides of the toy car body 1, causing the toy car body 1 to move backward in a straight line. When the user presses the third and fourth transmit buttons on the wireless transmitter module 3 again, the wireless transmitter module 3 transmits the third and fourth wireless open-circuit signals. Upon receiving these signals, the wireless receiver module E1 stops outputting high-level signals at pins 5 and 6, which then enter the power input terminals of relays J3 and J4. Relays J3 and J4 are de-energized and their control power input terminals and normally open contacts are open, thus stopping the toy car body 1 from moving backward in a straight line. Specifically, when the operator individually controls the positive and negative power input terminals of the motors on the left or right side of the toy car body 1 via the wireless transmitter module, the toy car body 1 moves forward, turns right, or turns left in a straight line; when the operator individually controls the positive and negative power input terminals of the motors on the left or right side of the toy car body 1 via the wireless transmitter module, the toy car body 1 moves backward, turns left, or turns right.
[0021] Figure 1 , 2As shown in Figure 3, when the toy car body 1 moves forward or backward at a distance far from an obstacle (such as a wall), the detector head of photoelectric detection module E2 or E3 outputs a high level to the positive control power input terminal of relays J1, J2 or J3, J4 within about 20 centimeters of the detector head due to the absence of an obstacle. The toy car body 1 is then wirelessly controlled to move forward or backward normally. When the toy car body 1 moves forward or backward at a distance close to an obstacle (such as a wall), the detector head of photoelectric detection module E2 or E3 stops outputting a high level to the positive control power input terminal of relays J1, J2 or J3, J4 within 20 centimeters of the detector head due to an obstacle. In this way, the toy car body 1 is no longer wirelessly controlled to move forward or backward (this does not affect the reverse control of the toy car body 1 moving forward or backward). This new invention can also control the toy car body 1 to move forward or backward using light control. Within a certain distance (e.g., within 10 meters), when the user aligns the transmitters of the two infrared emitting modules 2 with the convex lens 5 in front of the first infrared receiving module E4 on the front left and the second infrared receiving module E5 on the front right of the toy car body 1, and turns on the power switch of the two infrared emitting modules, the infrared beams emitted linearly by the infrared emitting modules 2 will be focused by the convex lens 5 onto the receivers of the first infrared receiving module E4 on the front left and the second infrared receiving module E5 on the front right. As a result, pin 3 of the infrared receiving modules E4 and E5 outputs a high level, thereby energizing relays J5 and J6 to control the power supply. When the input and normally open contacts close, relays J1 and J2 will be energized and their control power input and normally open contacts will close. Similar to wireless control, the toy car body 1 will move forward in a straight line (when the infrared beam is not shining in front of the receiver heads of infrared receiver modules E4 and E5, pin 3 of infrared receiver modules E4 and E5 will stop outputting a high level, relays J1 or J2 will be de-energized, and the toy car body will stop moving forward). Specifically, when the user points one of the infrared transmitter modules 2 at the convex lens 5 of the front left infrared receiver module E4 or the front right second infrared receiver module E5, the toy car body 1 will move forward in a straight line and turn right or left.When the user aligns the transmitters of the two infrared transmitter modules 2 with the convex lens 5 in front of the first infrared receiver module E6 on the left rear end and the second infrared receiver module E7 on the right rear end of the toy car body 1, and turns on the power switch of the two infrared transmitter modules, the infrared beams emitted linearly by the infrared transmitter modules 2 will be focused by the convex lens 5 onto the receivers of the first infrared receiver module E6 on the left rear end and the second infrared receiver module E7 on the right rear end. As a result, pin 3 of the infrared receiver modules E6 and E7 outputs a high level, which energizes relays J7 and J8, closing their control power input terminals and normally open contacts. Subsequently, relay J3... When J4 is energized, its control power input terminal and normally open contact terminal close. Similar to wireless control, the toy car body 1 will move backward in a straight line (when the infrared beam is not shining in front of the receiver heads of infrared receiver modules E6 and E7, pin 3 of infrared receiver modules E6 and E7 will stop outputting a high level, relay J3 or J4 will be de-energized, and the toy car body will stop moving forward). Specifically, when the user points one of the infrared transmitter modules 2 in front of the convex lens 5 of the rear left set of infrared receiver module E6 or the rear right set of infrared receiver module E7, the toy car body 1 will move backward in a straight line and turn left or right.
[0022] Figure 1 , 2 As shown in Figure 3, through the above-mentioned application, under the joint action of relevant institutions, children can not only wirelessly control the toy car to move forward or backward and turn, but also control the toy car to move forward or backward and turn by light control. Moreover, before the toy car moves forward or backward at a certain distance from an obstacle (such as a wall), the power supply of the motor controlling the toy car can be disconnected in time, preventing the toy car from being damaged. This can play a better role in protecting the toy car itself and improve children's knowledge of light control. Figure 3Among them, relays J1, J2, J3, J4, J5, J6, J7, and J8 are DC12V; wireless transmitter module 3 and wireless receiver module E1 are finished 433MHz wireless transmitter and receiver module components (working on the same principle as automotive wireless transmitter and receiver module components); photoelectric detection modules E2 and E3 are finished infrared sensor photoelectric detection modules of model E3F-DS30C4, which have two power input terminals and one signal output terminal. Depending on the selection, the signal output terminal outputs power or not when there is an obstacle or no obstacle in front of the detector head during operation; conversely, when there is an obstacle or no obstacle in front of the detector head... When there is no obstacle, the signal output terminal either does not output power or outputs power (in this embodiment, power is output when there is no obstacle in front). There is a distance adjustment knob at the rear of its housing. Adjusting to the left reduces the detection distance and adjusting to the right increases the detection distance (in this embodiment, it is adjusted to 20 cm). The infrared emitting module 2 and the infrared receiving modules E4, E5, E6, and E7 are finished infrared emitting and receiving components of model E3F-20C1 / L (there are two infrared emitting modules and four infrared receiving modules). When the infrared receiving component receives the infrared beam emitted by the infrared emitting module, the power output terminal outputs power; otherwise, it does not output power. The maximum detection distance is 20 meters.
