The temperature control signal can be directly transferred to the control module 5 by the wireless communication module 7, or sent to the control module 5 after being processed by the wireless communication module 7. It is not limited here, as long as the temperature control signal can enable the user to remotely control the temperature of part of the snowplow to rise or fall. In some embodiments, the operating device 6 can be set on the snowplow or separated from the snowplow. The user can control the temperature of at least part of the snow blower by means of the operating device 6 locally and / or remotely.

[0039] In some embodiments, the snowplow further includes a visual display device 8 and a button assembly 9, which are arranged on the main body 1 or the handle 3.

[0045] In some embodiments, Figure 7 As shown, the temperature of at least part of the working component 2 can be adjusted to prevent the working component 2 from freezing in a cold environment and affecting the normal use of the snowplow.

[0046] The rotating shaft 21 connects the main body housing 11 and the snow paddle 22. The temperature of at least part of the rotating shaft 21 is adjustable to prevent the rotating shaft 21 from freezing and affecting the normal operation of the snow paddle 22. The two ends of the rotating shaft 21 are respectively connected to the main body housing 11 through connecting pieces.

In some embodiments, the connecting piece is a bearing, and the temperature regulating device 10 is provided on the bearing.

[0047] The temperature of at least a portion of the snow paddle 22 is adjustable, so that after the snowplow is used, the snow attached to the snow paddle 22 is prevented from freezing in a cold environment, which would affect the next use. In some embodiments, a temperature regulating device 10 is provided at a portion of the snow paddle 22 where snow is accumulated, so as to heat the snow on the snow paddle 22 to prevent freezing.

[0048] The above-mentioned operating device 6 sends a control signal to the control module 5 through the wireless communication module 7. In some embodiments, continue to refer to Figure 2 As shown, the wireless communication module 7 includes a Wifi unit, and the operating device 6 sends a temperature control signal to the control module 5 through the Wifi unit, thereby realizing a wireless communication connection between the operating device 6 and the control module 5 .

[0049] Reference Figure 3 As shown, the wireless communication module 7 includes a Bluetooth unit, and the operating device 6 sends a temperature control signal to the control module 5 via the Bluetooth unit, thereby realizing a wireless communication connection between the operating device 6 and the control module 5 .

[0050] In some other embodiments, the wireless communication module 7 includes a Wifi unit and a Bluetooth unit, and the operating device 6 can send a temperature control signal to the control module 5 through any one of the units, thereby increasing the optionality of wireless connection between the operating device 6 and the control module 5.

[0051] The operating device 6 sends a temperature control signal to the control module 5 through the wireless communication module 7. In some other embodiments, the operating device 6 can also send a control signal to the control module 5 to control components such as the snowplow motor and the travel motor, or send a control signal to the control module 5 to adjust the working mode of the snowplow.

[0052] The operating device 6 can be a remote controller or a smart device, such as a mobile phone, a smart watch, a tablet computer, a computer, etc. The operating device 6 can be installed on the main body 1 of the snowplow, and the operating device 6 has a matching button. Pressing the matching button can start pairing and connection with the control module 5 on the snowplow, so as to perform corresponding operation control on the snowplow.

[0053] See also Figure 4 As shown, the control module 5 can control the temperature regulating device 10 to heat the components provided with the temperature regulating device 10, such as the handle 3, the visual display device 8 and the working component 2. The control module 5 exchanges information with the wireless communication module 7, and the operating device 6 sends a signal to the wireless communication module 7. The energy device 4 supplies power to the control module 5, and at the same time, the energy device 4 can also supply power to the wireless communication module 7. When the snowplow is equipped with the energy device 4, but the whole machine is not powered on, the control module 5 is not powered by the energy device 4, and the snowplow is in a standby state. That is to say, when the snowplow is in a standby state, the energy device 4 is connected to the snowplow, but does not supply power to the snowplow except for the wireless communication module 7. Only the wireless communication module 7 is always kept in the powered-on state to receive the instructions issued by the user, saving energy consumption. In the standby state, the energy device 4 only supplies power to the wireless communication module 7 to keep the wireless communication module 7 working normally. At this time, the energy consumption of the wireless communication module 7 is small, and the signal sent by the operating device 6 can be received at any time. After the wireless communication module 7 receives the signal sent by the operating device 6, it wakes up the energy device 4 through the control module 5 to power on the snowplow except for the wireless communication module 7, which is convenient, energy-saving and environmentally friendly. The control module 5 includes a step-down module. The step-down module is arranged on the PCB board 814. The energy device 4 supplies power to at least part of the wireless communication module 7 through the step-down module. The step-down module can reduce the voltage provided by the energy device 4 to the voltage required by the wireless communication module 7. In some embodiments, the step-down module reduces the voltage of 60V, 56V, 48V, or 40V to 5V, 3.3V, 2.5V, or 1.8V.

[0054] In some embodiments, the wireless communication module 7 may also be powered by a separate second energy device, such as a button battery, a dry cell battery, etc., so that the wireless communication module 7 is always powered on.

[0055] like Figure 8 As shown, the control module 5 includes a switch board 12 and a battery management system 13 (Battery Management System). The user operates the operating device 6 and remotely sends a signal to the wireless communication module 7. After receiving the signal sent by the operating device 6, the wireless communication module 7 sends a signal to the switch board 12. The switch board 12 grounds the enabling pin of the battery management system 13 through the EIA-485 communication protocol or other communication protocols, and the battery management system 13 is activated and supplies power to the snowplow. The control module 5 controls the temperature change of some snowplows. In this way, the temperature of some snowplows is adjusted.

[0056] In this embodiment, the control process for heating the handle 3 is as follows. The user operates the operating device 6 and sends a signal to the wireless communication module 7. The wireless communication module 7 sends a signal to the switch board 12. The switch board 12 activates the battery management system 13, and the battery management system 13 enables the PCB board 814 to be powered. The step-down module of the PCB board 814 converts the large voltage provided by the energy device 4 into a small voltage and heats the temperature regulating device 10. The snow blower includes a first temperature sensor 14. The first temperature sensor 14 is arranged on the switch board 12. The first temperature sensor 14 detects the ambient temperature and sends a control signal to the PCB board through the detected ambient temperature. When the temperature is low, the PCB board 814 uses a larger heating power to heat the temperature regulating device 10, and when the temperature is high, the PCB board 814 uses a smaller heating power to heat the temperature regulating device 10. In this embodiment, the heating power includes P1, P2, P3 and P4, and P1>P2>P3>P4. When the temperature is less than -10 degrees, the heating power is P1. When the temperature is greater than or equal to -10 degrees and less than 0 degrees, the heating power is P2. When the temperature is greater than or equal to 0 degrees and less than 15 degrees, the heating power is P3. When the temperature is greater than or equal to 15 degrees, the heating power is P4. The control module 5 includes a temperature sensor for detecting the temperature, which improves the heating efficiency and saves energy.

[0057] The snow blower includes a temperature switch 15. The temperature switch 15 is disposed in the circuit of the temperature regulating device 10. The temperature switch 15 detects the temperature at the temperature regulating device 10 and controls the circuit on and off according to the temperature at the temperature regulating device 10. When the temperature of the temperature regulating device 10 is greater than the preset temperature, the temperature switch 15 is disconnected. When the temperature of the temperature regulating device 10 is greater than 50°C, the temperature switch 15 is disconnected, and the temperature regulating device 10 does not continue to heat. In some embodiments, the preset temperature is greater than or equal to 30°C and less than or equal to 70°C. When the temperature of the temperature regulating device 10 is greater than 40°C, the temperature switch 15 is disconnected, and the temperature regulating device 10 does not continue to heat. In some embodiments, when the temperature of the temperature regulating device 10 is greater than 30°C, the temperature switch 15 is disconnected, and the temperature regulating device 10 does not continue to heat. In some embodiments, when the temperature of the temperature regulating device 10 is greater than 60°C, the temperature switch 15 is disconnected, and the temperature regulating device 10 does not continue to heat. In some embodiments, when the temperature of the temperature regulating device 10 is greater than 70°C, the temperature switch 15 is disconnected, and the temperature regulating device 10 does not continue to heat. In some embodiments, the temperature switch 15 detects the temperature of the handle 3 .

[0058] In some embodiments, a second temperature sensor is provided near the temperature regulating device 10. The second temperature sensor is connected to the switch board 12 or the PCB board 814, and detects the temperature of the temperature regulating device 10. When the second temperature sensor detects that the temperature near the temperature regulating device 10 is greater than 50°C, the PCB board 814 stops the power supply to the temperature regulating device 10. The maximum heating temperature is set for the temperature regulating device 10 through the temperature switch 15 or the second temperature sensor, thereby improving safety and avoiding scalding the user.

[0059] The above shows and describes the basic principles, main features and advantages of the present application.
