[0043] In one embodiment, Figure 1 As shown, a motorcycle voltage stabilization control circuit 10 is provided, comprising: a bridge switch charging circuit 102 , a speed detection module 104 , a bridge short-circuit voltage regulation circuit 106 , a voltage sampling circuit 108 and a control circuit 110 .

[0044] The input end of the bridge switching charging circuit 102 is connected to the output end of the generator 20, and the output end of the bridge switching charging circuit 102 is connected to the load 30. The bridge switching charging circuit 102 is used to transmit the electrical energy generated by the generator 20 to the load 30 on the motorcycle that requires electrical energy to maintain the operation of the motorcycle.

[0045] The rotation speed detection module 104 is connected to the bridge switch charging circuit 102 ; the rotation speed detection module 104 is used to detect the rotation speed of the generator 20 .

[0046] The bridge short-circuit voltage regulating circuit 106 is connected to the bridge switch charging circuit 102 .

[0047] The bridge switching charging circuit 102 is used to convert the AC power output by the generator 20 into DC power and output this DC power to the load 30. The bridge short-circuit voltage regulator circuit 106 is a circuit that performs voltage regulation based on a bridge circuit structure (such as a full-bridge or half-bridge configuration), ensuring that the voltage input to the load 30 is always within a safe voltage range. Specifically, the bridge short-circuit voltage regulator circuit 106 may include a bridge rectifier, a filter capacitor, a linear regulator or a switching regulator to ensure output voltage stability, and a current-limiting resistor.

[0048] The voltage sampling circuit 108 is used to collect the output voltage of the bridge switch charging circuit 102 .

[0049] The control circuit 110 is connected to the speed detection module 104, the voltage sampling circuit 108, and the bridge short-circuit voltage regulation circuit 106. The control circuit 110 is configured to output a first electrical signal when the speed is greater than a preset speed, and to output a second electrical signal when the speed is less than or equal to the preset speed and a zero-crossing point of the output voltage is detected. The preset speed can be determined based on the performance of the motorcycle to ensure that the voltage remains stable during use. For example, the preset speed can be 2000 rpm.

[0050] The first electrical signal is used to drive the bridge short-circuit voltage regulation circuit 106 to stop working; the second electrical signal is used to drive the bridge short-circuit voltage regulation circuit 106 to work, so as to perform zero-crossing short-circuit voltage regulation on the bridge switch charging circuit 102 .

[0051] The control circuit 110 obtains the speed measured by the speed detection module 104. When the speed is greater than the preset speed, the control circuit 110 outputs a first electrical signal to drive the bridge short-circuit voltage regulation circuit 106 to stop working. The current output by the generator 20 is supplied to the load 30 via the bridge switch charging circuit 102. The motorcycle is in a switch voltage regulation state, and the voltage of the motorcycle is adjusted by the switch voltage regulation method to achieve voltage stabilization. When the speed is less than or equal to the preset speed and the zero crossing point of the output voltage is detected, the control circuit 110 outputs a second electrical signal to drive the bridge short-circuit voltage regulation circuit 106 to work. At this time, the motorcycle enters the short-circuit voltage regulation state. The bridge short-circuit voltage regulation circuit 106 can support the zero-crossing short-circuit voltage regulation function of the motorcycle.

[0052] The motorcycle voltage stabilization control circuit 10 includes a bridge switch charging circuit 102, a speed detection module 104, a bridge short-circuit voltage regulation circuit 106, and a control circuit 110. The control circuit 110 obtains the speed of the generator 20 detected by the speed detection module 104, and when the speed is greater than a preset speed, outputs a first electrical signal to drive the bridge short-circuit voltage regulation circuit 106 to stop working and enter the motorcycle's switch voltage regulation state. When the speed is less than or equal to the preset speed and the output voltage crosses a zero point, the control circuit 110 outputs a second electrical signal to drive the bridge short-circuit voltage regulation circuit 106 to operate, thereby performing zero-crossing short-circuit voltage regulation on the bridge switch charging circuit 102 and entering the motorcycle's short-circuit voltage regulation state. Therefore, a motorcycle equipped with the motorcycle voltage stabilization control circuit 10 can enter the switch voltage regulation state or the short-circuit voltage regulation state based on the speed of the generator 20, thereby enhancing the motorcycle's voltage stabilization performance and improving the motorcycle's driving safety.

[0053] It should be noted that the motorcycle voltage stabilization control circuit 10 provided in the embodiment of the present application is a hardware improvement solution, which mainly uses the connection of various parts to solve the above-mentioned technical problems. The control circuit 110 part can realize the output of the above-mentioned first electrical signal and the second electrical signal based on the existing single-chip microcomputer control program or hardware such as comparators.

[0054] For example, in one embodiment, the control circuit 110 may include a first comparator, wherein an input of the first comparator is connected to the output of the speed detection module 104, a reference terminal of the first comparator is connected to a first reference voltage corresponding to a preset speed, and an output of the first comparator is connected to a controlled terminal of the bridge short-circuit voltage regulator circuit 106.

[0055] When the input signal of the first comparator is greater than the first reference voltage, the first electrical signal is output. When the input signal of the first comparator is less than or equal to the first reference voltage, the second electrical signal is output. The first electrical signal and the second electrical signal can be signals of opposite levels. For example, the first electrical signal is at a high level and the second electrical signal is at a low level; or the first electrical signal is at a low level and the second electrical signal is at a high level. The selection of high and low levels can be based on the specific structure of the bridge short-circuit voltage regulator circuit 106. In principle, the first electrical signal can be applied to drive the bridge short-circuit voltage regulator circuit 106 to stop working; and the second electrical signal can be applied to drive the bridge short-circuit voltage regulator circuit 106 to work, thereby performing zero-crossing short-circuit voltage regulation on the bridge switch charging circuit 102.

[0056] Furthermore, the first comparator may be a digital comparator or an analog comparator.

[0057] Furthermore, the first comparator may also achieve outputs of different levels by combining different types of logic gates, triggers, switches and other devices, thereby distinguishing the first electrical signal from the second electrical signal.

[0058] Similarly, in one embodiment, the control circuit 110 may further include a second comparator and a monostable trigger. The input of the second comparator is connected to the output of the voltage sampling circuit 108. The reference terminal of the first comparator is used to receive a second reference voltage, which is 0 volts. The output of the second comparator is connected to the input of the monostable trigger; the output of the monostable trigger is connected to the controlled terminal of the bridge short-circuit voltage regulator circuit 106.

[0059] When the voltage at the input terminal of the second comparator is greater than or less than 0, the output signal of the second comparator will change, and the monostable trigger is connected to the output of the second comparator to generate a pulse signal and output it to the controlled end of the bridge short-circuit voltage regulation circuit 106, thereby controlling the bridge short-circuit voltage regulation circuit 106 to stop working.

[0060] Furthermore, the motorcycle voltage stabilization control circuit 10 may be provided with a built-in power supply to supply power to the control circuit 110 .

[0061] In one embodiment, Figure 2 As shown, the motorcycle voltage stabilization control circuit 10 further includes: a charging control shutdown circuit 112 .

[0062] The charge control shutdown circuit 112 is connected in series to the path where the bridge switch charging circuit 102 charges the load 30 .

[0063] The control circuit 110 is also connected to the charge control shutdown circuit 112. The control circuit 110 is further configured to output a third electrical signal when the output voltage is greater than a preset voltage. The third electrical signal is configured to drive the charge control shutdown circuit 112 to shut down.

[0064] The control circuit 110 obtains and compares the output voltage of the bridge switch charging circuit 102 with a preset voltage, and when the output voltage is greater than the preset voltage, outputs a third electrical signal to the charging control shutdown circuit 112 to drive the charging control shutdown circuit 112 to shut down, thereby cutting off the power transmission path from the bridge switch charging circuit to the load 30, thereby avoiding overcharging of the load 30 and improving the safety of the motorcycle.

[0065] The preset voltage can be determined according to the rated voltage of the load 30 of the motorcycle to ensure that the load 30 is within a safe voltage range at any time.

[0066] In one embodiment, Figure 2As shown, the control circuit 110 includes: a control shutdown module 1102 , a trigger opening module 1104 and a processing circuit 1106 .

[0067] The control shutdown module 1102 is connected in parallel with the bridge short-circuit voltage regulating circuit 106 .

[0068] The controlled end of the trigger opening module 1104 is connected to the control end of the control shutoff module 1102 , and the output end of the trigger opening module 1104 is connected to the controlled end of the bridge short-circuit voltage regulating circuit 106 .

[0069] The processing circuit 1106 is respectively connected to the speed detection module 104 and the controlled end of the control shutdown module 1102. The processing circuit 1106 is used to drive the control shutdown module 1102 and the trigger opening module 1104 to open when the speed is less than or equal to the preset speed and the zero crossing point of the output voltage is detected, so as to output a second electrical signal to the bridge short-circuit voltage regulation circuit 106 through the trigger opening module 1104.

[0070] The processing circuit 1106 is further configured to drive the shutdown module 1102 to shut down when the rotational speed is greater than a preset rotational speed.

[0071] When the shutdown control module 1102 is turned on, the shutdown control module 1102 drives the trigger opening module 1104 to turn on, thereby outputting a second electrical signal to the bridge short-circuit voltage regulation circuit 106, and the motorcycle enters the short-circuit voltage regulation state. When the shutdown control module 1102 is turned off, the shutdown control module 1102 is also turned off, thereby outputting a first electrical signal to the bridge short-circuit voltage regulation circuit 106, and the motorcycle enters the switch voltage regulation state.

[0072] In one embodiment, Figure 2 As shown, when the motorcycle voltage stabilization control circuit 10 includes the charging control shutdown circuit 112 , the motorcycle voltage stabilization control circuit 10 further includes: a charging triggering opening circuit 114 .

[0073] The charging triggering and enabling circuit 114 is connected in series to the path of the bridge switch charging circuit 102 charging the load 30 , and the controlled terminal of the charging triggering and enabling circuit 114 is connected to the control terminal of the charging control shutoff circuit 112 , and the output terminal of the charging triggering and enabling circuit 114 is connected to the controlled terminal of the bridge switch charging circuit 102 .

[0074] The on-off state of the charge triggering on circuit 114 is opposite to that of the charge control shut-off circuit 112 .

[0075] When the output voltage is greater than a preset voltage, the control circuit 110 drives the charge control shutdown circuit 112 to shut down, thereby cutting off the power supply circuit between the bridge switch charging circuit 102 and the load 30 to prevent overvoltage on the load 30. When the charge control shutdown circuit 112 is shut down, the charge control shutdown circuit 112 sends an electrical signal to the charge trigger enable circuit to stop the bridge switch charging circuit 102.

[0076] Correspondingly, when the output voltage is less than or equal to the preset voltage, the control circuit 110 drives the charging control shutdown circuit 112 to close, thereby turning on the power circuit between the bridge switch charging circuit 102 and the load 30; when the charging control shutdown circuit 112 is closed, the charging control shutdown circuit 112 sends a corresponding electrical signal to the charging trigger opening circuit to resume operation of the bridge switch charging circuit 102, thereby resuming power supply to the load 30.

[0077] Therefore, the charge triggering circuit 114 sends a corresponding electrical signal to the bridge switch charging circuit 102 according to the state of the charge control shutoff circuit 112 .

[0078] In one embodiment, Figure 2 As shown, the motorcycle voltage stabilization control circuit 10 further includes a reverse connection protection circuit 116 .

[0079] The reverse connection protection circuit 116 is connected in series to a common path between the bridge switch charging circuit 102 , the bridge short-circuit voltage regulating circuit 106 and the load 30 .

[0080] The reverse connection protection circuit 116 includes devices such as diodes or relays, thereby preventing circuit damage caused by reverse connection of energy storage devices such as batteries in the motorcycle, thereby improving the safety of the motorcycle.

[0081] In one embodiment, Figure 2 As shown, the motorcycle voltage stabilization control circuit 10 further includes a filter circuit 118 .

[0082] The filter circuit 118 is connected in series to a common path between the bridge switch charging circuit 102 , the bridge short-circuit voltage regulating circuit 106 and the load 30 .

[0083] The filter circuit 118 can smooth the electrical signal input to the load 30 , so that the load 30 operates under a smooth and stable electrical signal, thereby improving the stability of the motorcycle.

[0084] In one embodiment, Figure 2 As shown, the motorcycle voltage stabilization control circuit 10 further includes: an energy storage module 120 .

[0085] The energy storage module 120 is connected in series to a common path between the bridge switch charging circuit 102, the bridge short-circuit voltage regulating circuit 106 and the load 30. The energy storage module 120 can be used to store the electrical energy output by the bridge switch charging circuit.

[0086] In one embodiment, Figure 2 As shown, the motorcycle voltage stabilization control circuit 10 further includes a phase voltage zero-crossing detection circuit 122 when the generator 20 includes a multi-phase output.

[0087] The phase voltage zero-crossing detection circuit 122 is connected to the control circuit 110 , and is used to detect the output voltage of each phase of the generator 20 .

[0088] Phase voltage zero-crossing detection circuit 122 detects the moment when the waveform of the AC signal output by generator 20 switches from positive to negative, or vice versa, thereby controlling the electrical signal. Specifically, when the AC signal switches at zero, it does not impact load 30, thereby improving the safety of the motorcycle.

[0089] In one embodiment, the motorcycle voltage stabilization control circuit 10 further includes a speed zero-crossing sampling circuit.

[0090] The speed zero-crossing sampling circuit is connected to the bridge switch charging circuit 102 , the speed detection module 104 and the control circuit 110 respectively.

[0091] In one embodiment, a motorcycle is provided, comprising the motorcycle voltage stabilization control circuit as described above.

[0092] A motorcycle equipped with the motorcycle voltage stabilization control circuit can enter a switching voltage regulation state or a short-circuit voltage regulation state based on the rotational speed of the generator, thereby enhancing the voltage stabilization performance of the motorcycle and improving the driving safety of the motorcycle.
