[0002] In pursuit of racing speed, existing toy remote-controlled cars have switched from external dry-cell batteries, nickel-metal hydride batteries, and nickel-cadmium batteries to more powerful lithium batteries. Current solutions for toy remote-controlled cars use a motor drive with a receiver chip and a lithium battery charging chip to drive the motor and charge the lithium battery. However, the lithium battery charging chip and the motor with receiver chip typically operate independently. This means that while the lithium battery charging chip is charging the lithium battery, the motor with receiver chip is also outputting a drive signal when it receives a remote control signal. This can cause the remote-controlled car to start even if the charging plug is not unplugged, posing a safety hazard.

Detailed Implementation

To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following detailed description, with reference to the accompanying drawings and examples, further illustrates the utility model. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the scope of the utility model.

It should also be understood that terms such as those defined in general dictionaries should be understood to have the same meaning as in the context of the prior art, and should not be interpreted in an idealized or overly formal sense unless specifically defined as herein.
[0047] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
[0048] The inventors discovered that existing remote-controlled toy car solutions use a motor drive chip with a receiver and a lithium battery charging chip to drive the motor and charge the lithium battery. However, the lithium battery charging chip and the motor with receiver usually operate independently. This means that while the lithium battery charging chip is charging the battery, the motor with receiver also outputs a drive signal when it receives a remote control signal. This can cause the remote-controlled car to start even if the charging plug is not unplugged, posing a safety hazard. Furthermore, to prevent battery damage, a lithium battery protection chip is usually added, which requires additional external logic control, making the entire circuit complex and resulting in poor coordination between different parts.
[0049] To address the aforementioned technical problems, this utility model provides a toy remote control car receiver with a drive circuit, system, and toy remote control car. By connecting the charging module to the drive module, when the charging module charges the lithium battery, it outputs a charging signal to the drive module. This ensures that even if the drive module receives a remote control signal while detecting that the lithium battery is charging, it will not start the toy remote control car, thus avoiding the safety hazard caused by accidental start-up while the toy remote control car is charging. Furthermore, by integrating an undervoltage protection unit into the drive module, low-voltage detection is achieved, preventing damage to the lithium battery due to undervoltage. Compared to solutions that rely on adding a lithium battery protection chip, this approach offers higher integration and a simpler circuit.
[0050] Please also refer to Figures 1 to 4 This utility model provides a preferred embodiment of a toy remote control car receiver with a drive circuit.
[0051] In some embodiments, such as Figure 1 As shown, this utility model provides a toy remote control car receiver with a drive circuit, which includes a charging module 100 and a drive module 200. The charging module 100 is connected to the drive module 200, and the charging module 100 is used to charge a lithium battery 300 and output a charging signal to the drive module 200 when charging; the drive module 200 is connected to the charging module 100, and the drive module 200 is used to drive a motor to work according to the received remote control signal, and to stop driving the motor to work when the charging signal is received.
[0052] In this embodiment, the charging module 100 and the drive module 200 can operate independently. When the toy remote control car is charging, the charging module 100 charges the lithium battery 300. At this time, the drive module 200 can receive a charging signal fed back by the charging module 100. This charging signal is a trigger signal. After receiving the charging signal, the drive module 200 shuts down functions such as high-frequency motor drive decoding, and no output drive motor will operate. In this way, by connecting the charging module 100 and the drive module 200, when the charging module 100 charges the lithium battery 300, it outputs a charging signal to the drive module 200. This ensures that even if the drive module 200 receives a remote control signal when it detects that the lithium battery 300 is charging, it will not drive the toy remote control car to start. This avoids the safety hazards caused by the toy remote control car being accidentally triggered to start while charging, improves safety, and reduces power consumption.
[0053] In some embodiments, such as Figure 1 As shown, the drive module 200 includes: a signal amplification unit 210, a signal decoding unit 220, a drive output unit 230, a clock and logic processing unit 240, a charging communication unit 250, and a power supply and reference unit 260. The signal amplification unit 210 receives remote control signals; the signal decoding unit 220 is connected to the signal amplification unit 210 and is used to decode the received remote control signals; the drive output unit 230 is connected to the signal decoding unit 220 and is used to drive the motor 500; the clock and logic processing unit 240 is connected to both the signal decoding unit 220 and the drive output unit 230, and is used to control the operation of both the signal decoding unit 220 and the drive output unit 230. The charging communication unit 250 is connected to the charging module 100 and the clock and logic processing unit 240 respectively. The charging communication unit 250 is used to output a shutdown signal to the clock and logic processing unit 240 when the charging signal is received. The clock and logic processing unit 240 is also used to control the signal decoding unit 220 and the drive output unit 230 to be in a stopped working state according to the shutdown signal. The power supply and reference unit 260 is connected to the clock and logic processing unit 240 and is used to provide power to the clock and logic processing unit 240.
[0054] In this embodiment, the signal amplification unit 210, signal decoding unit 220, drive output unit 230, clock and logic processing unit 240, charging communication unit 250, and power supply and reference unit 260 are integrated on a single chip. The signal amplification unit 210 receives the remote control signal emitted by the remote control handle, amplifies the signal, and outputs it to the signal decoding unit 220. The signal decoding unit 220 decodes the amplified remote control signal and outputs it to the drive output unit 230. The drive output unit 230 drives the motor to operate, for example, forward or backward, based on the decoded remote control signal. The clock and logic processing unit 240 provides clock and logic control for the signal decoding unit 220 and drive output unit 230, and the power supply and reference unit 260 provides power to the clock and logic processing unit 240. The charging communication unit 250 is connected between the charging module 100 and the clock and logic processing unit 240. It can receive the charging signal fed back by the charging module 100 and output a shutdown signal to the clock and logic processing unit 240 when it receives the charging signal, so that the clock and logic processing unit 240 will not control the signal decoding unit 220 and the drive output unit 230 to work.
[0055] In some embodiments, such as Figure 1 As shown, the drive module 200 also includes an undervoltage protection unit 270, which is connected to the clock and logic processing unit 240 and the power supply and reference unit 260 respectively. The undervoltage protection unit 270 is used to detect the battery voltage.
[0056] In this embodiment, the power supply and reference unit 260 can provide a reference voltage for the undervoltage protection unit 270. The undervoltage protection unit 270 is integrated inside the drive module 200 and can realize the chip low voltage detection function. When the battery voltage is lower than the set value, the drive module 200 shuts down the corresponding module and enters an extremely low ground standby state to prevent the lithium battery 300 from being damaged due to undervoltage. Compared with the existing technology that uses an additional lithium battery protection chip, the integration is higher, the circuit is simpler, and it is more conducive to coordinated control.
[0057] In some embodiments, such as Figure 1 and Figure 2As shown, the charging module 100 includes: a charging unit 110, a temperature feedback unit 120, a constant current feedback unit 130, a constant voltage feedback unit 140, and a low voltage and short circuit feedback unit 150. The charging unit 110 is connected to the charging communication unit 250. The charging unit 110 charges the lithium battery 300 and outputs a charging signal to the charging communication unit 250 when charging. The temperature feedback unit 120 is connected to the charging unit 110. The temperature feedback unit 120 detects the temperature during charging and feeds it back to the charging unit 110. The constant current feedback unit 130 is connected to the charging unit 110. The constant current feedback unit 130 detects the constant current and feeds it back to the charging unit 110. The constant voltage feedback unit 140 is connected to the charging unit 110. The constant voltage feedback unit 140 detects the constant voltage and feeds it back to the charging unit 110. The low voltage and short circuit feedback unit 150 is connected to the charging unit 110. The low voltage and short circuit feedback unit 150 detects low voltage signals and short circuit signals and feeds them back to the charging unit 110.
[0058] In this embodiment, the charging module 100 can be connected to an external power source to charge the lithium battery 300. By integrating a temperature feedback unit 120 within the charging module 100 to detect the charging temperature, and by using a constant current feedback unit 130, a constant voltage feedback unit 140, and a low voltage and short circuit feedback unit 150 to detect the constant current state, constant voltage state, and low voltage and short circuit state of the charging module 100, the overall chip can be fully utilized for heat dissipation, charging the lithium battery with the maximum safe and reliable charging current, thus improving charging efficiency. It should be noted that the circuit structure of the charging module 100, temperature feedback unit 120, constant current feedback unit 130, constant voltage feedback unit 140, and low voltage and short circuit feedback unit 150 are existing mature circuits and will not be described in detail here.
[0059] In some embodiments, such as Figure 1 and Figure 3 As shown, the charging communication unit 250 includes a signal sampling circuit 251 and a comparison circuit 252. The signal sampling circuit 251 is connected between the charging module 100 and the comparison circuit 252, and is used to sample the charging signal output by the charging module 100. The comparison circuit 252 is connected between the signal sampling circuit 251 and the clock and logic processing unit 240, and is used to output a shutdown signal to the clock and logic processing unit 240 according to the charging signal.
[0060] In this embodiment, the input terminal of the signal sampling circuit 251 is connected to the charging unit 110, and the output terminal of the signal sampling circuit 251 is connected to the input terminal of the comparison circuit 252. The signal sampling circuit 251 can feed back the charging signal output by the charging unit 110 to the comparison circuit 252. When the comparison circuit 252 detects the charging signal, it can output a shutdown signal to the clock and logic processing unit 240 so that the drive module 200 will not drive the motor to work.
[0061] In some embodiments, the signal sampling circuit 251 includes a first resistor R1 and a second resistor R2; one end of the first resistor R1 is connected to the charging module 100, and the other end of the first resistor R1 is connected to one end of the second resistor R2 and the input terminal of the comparison circuit 252; the other end of the second resistor R2 is grounded.
[0062] Furthermore, the comparison circuit 252 includes a comparator, the input terminal of the comparator P1 is connected to the common terminal of the first resistor R1 and the second resistor R2, and the output terminal of the comparator P1 is connected to the clock and logic processing unit 240.
[0063] In this embodiment, the signal sampling circuit 251 is implemented by connecting the first resistor R1 and the second resistor R2 in series. The signal sampling circuit 251 is integrated into the driving module 200, and the charging unit 110 inputs the charging signal to the signal sampling circuit 251 through the enable pin EN of the driving module 200. The comparator P1 can perform hysteresis comparison on the input charging signal, and when a charging signal is input, it can output a shutdown signal (high level signal) to the clock and logic processing unit 240.
[0064] In some embodiments, such as Figure 4 As shown, this utility model also provides a toy remote control car receiver belt drive system, which includes a lithium battery 300, a charging interface 400, a motor 500, and the toy remote control car receiver belt drive system as described above; the charging port of the lithium battery 300 is connected to the charging module 100, and the output terminal of the lithium battery 300 is connected to the drive module 200; the charging interface 400 is connected to the input terminal of the lithium battery 300; the motor 500 is connected to the drive module 200.
[0065] In this embodiment, the charging interface 400 is connected to an external power source, which is then connected to the charging module 100. The charging module 100 charges the lithium battery 300. The lithium battery 300 is connected to the power supply pin VDDP of the drive module 200 to supply power to the drive module 200. The drive module 200 drives the motor 500 to operate, enabling the toy remote control car to perform forward and backward movements. The charging module 100 is connected to the enable pin EN of the drive module 200, and when charging the lithium battery 300, it inputs a charging signal to the enable pin EN of the drive module 200.
[0066] In some embodiments, the charging interface 400 may be, but is not limited to, a USB interface.
[0067] In some embodiments, the present invention also provides a toy remote control car, which includes a remote control handle and a toy remote control car receiver with a drive system as described above.

[0069] By connecting the charging module to the drive module, when the charging module charges the lithium battery, it outputs a charging signal to the drive module. This prevents the drive module from starting the toy remote control car even if it receives a remote control signal when it detects that the lithium battery is charging. This avoids the safety hazards caused by the toy remote control car being accidentally triggered to start while charging.
[0070] By integrating an undervoltage protection unit into the drive module, low-voltage detection of the drive module is achieved, preventing damage to the lithium battery due to undervoltage.
