Description

Technical Field

[0001] The utility model relates to the technical field of model car control, and particularly relates to a remote control model car system. Background Art

[0002] A remote control model car is abbreviated as RC Car (Remote control, or Radio control), or simply called a remote control car, which is a subclass of models. A remote control model car generally consists of a remote control car body, a remote controller and a receiver. A remote control model car is a model car that is controlled remotely, that is, a remote control model. Remote control model cars are becoming increasingly popular among young people.

[0003] A remote control model car is not a toy. It has a power system (such as an engine) that is the same as or similar to that of a car. In addition, it also has a suspension system and high-performance tires and other structures. A remote control model car is a special model car. During the operation and driving process of a remote control model car, the smoothness and responsiveness of the vehicle's driving speed are very important for operation and viewing.

[0004] For existing model cars powered by a DC brushed motor, when driving on a slope or an uneven road section, the driving speed of the model car will be affected by the road conditions, resulting in the model car being unresponsive or difficult to control during operation. The main reasons are as follows: when the model car is driving at a constant speed and encounters a downhill section, the speed of the model car will increase due to the influence of gravity, making it difficult to control; when the model car is driving at a constant speed and encounters an uphill section, the speed of the model car will decrease due to the influence of gravity, making it difficult to control. Summary of the Invention

[0005] In view of the above-mentioned existing technical situation, the present utility model is proposed. Its purpose is to provide a remote control model car system that can adjust the vehicle speed of a remote control model car in real time so that the remote control model car can drive stably.

[0028] Hereinafter, with reference to the accompanying drawings, the remote control model car system, remote control model car and speed control method of the remote control model car involved in the present utility model will be described in detail.

[0029] Figure 1 It is a functional module diagram showing the remote control model car system S involved in the example of the present utility model. Figure 2 It is a functional module diagram showing the remote control model car 1 involved in the example of the present utility model.

[0030] Refer to Figure 1 , the first aspect of the present utility model relates to a remote control model car system S.

[0031] In some examples, the remote control model car system S may include a remote control model car 1 and a remote controller 2. The remote controller 2 can be used to control the movement of the remote control model car 1.

[0032] In some examples, the remote control model car 1 can be an electric remote control car. In some examples, the remote control model car 1 can be a drift car, a racing car, a climbing car, an off-road vehicle, a big foot car, a simulation off-road vehicle, a container truck, etc.

[0033] Refer to Figure 2 , in some examples, the remote control model car 1 may include a vehicle body 11, a power motor 13, a receiver 14, an operation information detection module 17 and an electronic speed controller 12.

[0034] In some examples, the operation information detection module 17 can be configured to detect the operation information of the vehicle body.

[0035] In some examples, the receiver 14 can be configured to obtain the remote control instructions of the remote controller 2 and the running information of the vehicle body 11. In some examples, the receiver 14 can be configured to control the electronic speed governor 12 to adjust the second rotational speed to the first rotational speed when it is determined that the remote control instructions have not changed and the running information has changed. In some examples, the rotational speed of the power motor is the first rotational speed when the running information has not changed, and the rotational speed of the power motor is the second rotational speed when the running information has changed, and the first rotational speed is different from the second rotational speed.

[0036] In the remote control model vehicle system according to the first aspect of the present invention, when the receiver 14 determines that the remote control instructions have not changed and the running information has changed, it can control the electronic speed governor 12 to adjust the second rotational speed to the first rotational speed. Wherein, the rotational speed of the power motor is the first rotational speed when the running information has not changed, and the rotational speed of the power motor is the second rotational speed when the running information has changed, and the first rotational speed is different from the second rotational speed. In this case, the electronic speed governor 12 can adjust the undesired second rotational speed to the first rotational speed in real time according to the remote control instructions of the remote controller 2 and the running information of the vehicle body, thereby being able to adjust the vehicle speed of the remote control model vehicle 1 in real time so that the remote control model vehicle 1 can run stably.

[0037] In some examples, the power motor 13 can be a brushed motor, and more specifically, a DC brushed motor. In other examples, the power motor 13 can also be a brushless motor.

[0038] Figure 3 It is a functional block diagram of the vehicle body 11 according to the examples of the present invention. Figure 4 It is a functional block diagram of the electronic speed governor 12 according to the examples of the present invention.

[0039] Refer to Figures 3 to 4 , in some examples, the remote control model vehicle 1 can include a power supply 15. The power supply 15 can be used to supply power to each module.

[0040] In some examples, the remote control model vehicle 1 can include a voltage detection module 16. The voltage detection module 16 can be configured to detect the voltage fluctuation information of the power supply 15 and output the voltage fluctuation information to the receiver 14, and the receiver 14 can judge the running information according to the voltage fluctuation information.

[0041] In some examples, the electronic speed governor 12 can convert the voltage fluctuation information into the real-time rotational speed of the power motor 13 through calculation.

[0042] Refer to Figure 3 , in some examples, the vehicle body 11 can include a body 110 and wheels 111.

[0043] In some examples, the running information may include at least one of the real-time rotational speed of the power motor 13, the first real-time traveling speed of the wheel 111, the real-time attitude of the vehicle body 110, and the second real-time traveling speed of the vehicle body 110.

[0044] In some examples, the remote control model vehicle 1 may include a running information detection module 17. The running information detection module 17 may be configured to detect the running information.

[0045] In some examples, the running information detection module 17 may be built into the power motor 13. Thus, it is convenient for the running information detection module 17 to detect the rotational speed of the power motor 13, and the internal installation space of the remote control model vehicle 1 can be saved.

[0046] In some examples, the running information detection module includes at least one of a rotational speed sensor, a speed sensor, and a gyroscope. The rotational speed sensor is configured to detect the real-time rotational speed, the speed sensor is configured to detect the second real-time traveling speed and / or the first real-time traveling speed, and the gyroscope is configured to detect the real-time attitude.

[0047] In some examples, the rotational speed sensor can be used to be disposed on the power motor 13 to detect the real-time rotational speed. In some examples, the speed sensor is disposed on the wheel 111 to detect the first real-time traveling speed, and / or the speed sensor is disposed on the vehicle body 110 to detect the second real-time traveling speed. In some examples, the gyroscope is disposed on the vehicle body 110 to detect the real-time attitude.

[0048] In some examples, the running information includes uniform motion.

[0049] In some examples, when the electronic speed controller 12 determines that the remote control instruction has not changed and the uniform motion becomes non-uniform motion, the second rotational speed can be adjusted to the first rotational speed. In other words, at this time, adjusting the second rotational speed to the first rotational speed means changing the changed non-uniform motion back to the original uniform motion. When the remote control model vehicle 1 is running on a steep slope or an uneven road surface, it is extremely easy for the vehicle speed to change, resulting in the instability of the remote control model vehicle 1, and it is also easy to cause the running state of the remote control model vehicle 1 to be inconsistent with the operation of the remote controller 2 (referred to as not following the hand). In this case, through the real-time adjustment of the electronic speed controller 12, the remote control model vehicle 1 can be maintained in the original uniform motion state, and the remote control model vehicle 1 can also achieve uniform driving on a steep slope or an uneven road surface, so as to ensure the stable driving of the remote control model vehicle 1, and at the same time, the remote control of the remote control model vehicle 1 can follow the hand.

[0050] In some examples, the receiver 14 may include a signal processing module 120 and a control module 121. The signal processing module 120 is configured to receive remote control instructions and operation information, process them, and then send them to the control module 121. The control module 121 can be used to control the electronic speed governor 12 to adjust the rotational speed of the power motor 13

[0051] Figure 5 is a flowchart showing the vehicle speed control method of the remote control model car 1 involved in the examples of the present utility model

[0052] Referring to Figure 5 , a second aspect of the present utility model relates to a vehicle speed control method for a remote control model car 1. The remote control model car 1 may include a power motor 13 and a vehicle body 11. The remote control model car 1 can adjust the vehicle speed by adjusting the rotational speed of the power motor 13. The vehicle speed control method of the remote control model car 1 may include the following steps:

[0053] Step S100, obtaining the remote control instructions of the remote controller 2

[0054] Step S200, obtaining the operation information of the vehicle body 11

[0055] Step S300, judging the change situations of the remote control instructions and the operation information

[0056] Step S400, when it is judged that the remote control instructions do not change and the operation information changes, adjusting the second rotational speed to the first rotational speed, where the rotational speed of the power motor 13 when the operation information does not change is the first rotational speed, and the rotational speed of the power motor 13 when the operation information changes is the second rotational speed

[0057] In the vehicle speed control method of the remote control model car 1 involved in the second aspect of the present utility model, when it is judged that the remote control instructions do not change and the operation information changes, the second rotational speed can be adjusted to the first rotational speed, where the rotational speed of the power motor 13 when the operation information does not change is the first rotational speed, and the rotational speed of the power motor when the operation information changes is the second rotational speed. The first rotational speed is different from the second rotational speed. In this case, the undesired second rotational speed can be adjusted to the first rotational speed in real time according to the remote control instructions of the remote controller 2 and the operation information of the vehicle body 11. Thus, the vehicle speed of the remote control model car 1 can be adjusted in real time so that the remote control model car 1 can travel stably

[0058] The vehicle speed control method of the remote control model car 1 involved in the examples of the present utility model can be implemented based on the remote control model car system S and the remote control model car 1 involved in the first aspect of the present utility model. For the specific embodiments of the remote control model car system S and the remote control model car 1, refer to the partial descriptions of the above remote control model car system S and the remote control model car 1, which will not be elaborated here

[0059] According to the present utility model, it is possible to provide a remote control model car system S and a speed control method for a remote control model car 1 that can adjust the speed of the remote control model car 1 in real time so that the remote control model car 1 can travel stably.

[0060] Although the present utility model has been specifically described above in conjunction with the accompanying drawings and examples, it should be understood that the above description does not limit the present utility model in any way. Those skilled in the art can make deformations and changes to the present utility model as needed without departing from the essence and scope of the present utility model, and these deformations and changes all fall within the scope of the present utility model.
