[0050] Please see Figure 1 and Figure 5 The vehicle 200 can be equipped with a winch 14 to assist the vehicle 200 in getting out of trouble or to help other vehicles 200 get out of trouble. The vehicle 200 includes a high-voltage system 100, which includes a power battery 18 and a winch assembly 10. The winch assembly 10 includes a first motor 12 and a winch 14. The power battery 18 is electrically connected to the first motor 12.

[0051] The winch 14 can be installed in the front compartment 19 of the vehicle 100. Specifically, one end of the cable of the winch 14 is fixed to the winch 14, and the other end is connected to a connector, which can fix the winch 14 to a target object (such as another vehicle or a fixed object) to anchor the vehicle 200 thereto. The winch 14 has a rotating shaft. When the first motor 12 is connected to the winch 14, the output shaft 16 of the first motor 12 can be connected to the rotating shaft. When the first motor 12 rotates, the output shaft 16 drives the rotating shaft to rotate, thereby causing the winch 14 to release and tighten the cable. Optionally, the winch 14 includes a reel on which the cable can be wound. The reel can be connected to the rotating shaft, and the cable can be tightened and released when the reel rotates.

[0052] In related technologies, the winch 14 is driven by a hydraulic system. When the winch 14 is working continuously, it is prone to stop working due to excessive temperature, causing the winch 14 to stop working as well, resulting in interruption of rescue and poor user experience.

[0053] In this embodiment, the first motor 12 and the winch 14 are configured to be installed in the vehicle 200. The first motor 12 is connected to the winch 14 and is electrically connected to the power battery 18 of the vehicle 200. The first motor 12 is configured to drive the winch 14 using the power battery 18, which is the battery that drives the drive motor of the vehicle 200. Thus, the first motor 12 can use the output voltage of the power battery 18 to drive the winch 14, improving the overheating problem when the first motor 12 drives the winch 14, thereby facilitating continuous operation of the winch 14 and enhancing the user experience. Specifically, the power battery 18 can be in the form of a battery pack or other types of power batteries.

[0054] It is understandable that the voltage of the power battery 18 is often as high as hundreds of volts. The first motor 12 is driven by the power battery 18. While ensuring a certain power, the current of the first motor 12 when it is working can be reduced, thereby reducing the heat generated by the first motor 12 and enabling the winch 14 to work continuously.

[0055] In some alternative embodiments, the operating voltage of the first motor 12 is greater than 250V.

[0056] The winch 14 is connected to the first motor 12, and the power battery 18 of the vehicle 200 supplies power to the first motor 12. Using the power battery 18 to power the first motor 12 has two advantages: firstly, it increases the operating voltage of the first motor 12 and reduces its operating current, preventing the hydraulic system from overheating and shutting down during continuous operation of the winch 14, thus avoiding rescue interruptions. Secondly, using the power battery 18 on the vehicle 200 to power the first motor 12 eliminates the need for an additional power supply for the winch assembly 10, saving installation space and manufacturing costs.

[0057] Optionally, to control the operation of the first motor 12, the winch assembly 10 of the vehicle 200 may include a first controller 20. The first controller 20 is connected to the first motor 12 and configured to use the output voltage of the power battery 18 to control the first motor 12 to drive the winch 14. The first controller 20 may include a microcontroller unit (MCU) with functions of bus data parsing, calculation, and driving. The first controller 20 is also connected to a power supply unit 21, which is electrically connected to and configured to supply power to the first controller 20.

[0058] The power supply unit 21 is a low-voltage power supply unit 21, which is connected to the first controller 20 to supply power to the first controller 20. The power supply unit 21 can be a low-voltage energy storage module configured on the vehicle 200 itself, or it can be a separately set low-voltage battery, which is electrically connected to the first controller 20.

[0059] Optionally, the first controller 20 is also configured to control the operation of the second motor 22. The second motor 22 may be a motor on the vehicle 200 that drives other accessories. By having the first controller 20 control the rotation of the first motor 12 and the second motor 22, the number of controllers required can be reduced, thereby lowering the cost of the vehicle 200.

[0060] Optionally, the second motor 22 can be the compressor motor 24 of the vehicle 200. In this way, the first controller 20 can control the operation of the vehicle 200 compressor motor 24 to drive the compressor, and the first controller 20 can also control the operation of the first motor 12 to drive the winch, for example, to tighten or release the cable. The first motor 12 and the compressor motor 24 can share the first controller 20. This reduces the number of controllers required and lowers the cost of the vehicle 200.

[0061] Furthermore, the first controller 20 is configured to control the operation of the first motor 12 according to a first control command, and to control the operation of the second motor 22 according to a second control command. The first and second control commands are generated by user operation according to user needs or according to commands from the high-voltage system 100.

[0062] Optionally, the first and second control commands can be generated via a physical switch 38. The physical switch 38 may take the form of, but is not limited to, a rotary switch, push-button switch, slide switch, etc., located within the vehicle 200. The first controller 20 is connected to the physical switch 38, and the user generates the first and second control commands by operating the physical switch 38. In one example, the first control command may be an instruction to control the winch 14 to tighten the cable; in another example, it may be an instruction to control the winch 14 to release the cable. In one example, the second motor 22 is the compressor motor 24 of the vehicle 200, and the second control command may be an instruction to control the vehicle's air conditioning to turn on, causing the compressor motor 24 to start at a target speed.

[0063] Optionally, the first and second control commands can be generated via a virtual switch. The virtual switch may include a virtual switch displayed on a display unit of the vehicle 200, and the user can generate the first control command by operating (long press or short press, etc.) the virtual switch of the winch 14 through the vehicle's display unit.

[0064] Furthermore, the first controller 20 can communicate with the user's terminal device 40, which includes, but is not limited to, car keys, tablets, smartphones, wearable smart devices, etc. The user generates a first control command and / or a second control command through the corresponding control switch on the terminal device 40.

[0065] Optionally, the first and second control commands can be generated via voice commands. The first controller 20 is connected to a voice component on the vehicle 200, which can collect user voice commands, thereby enabling the first controller 20 to generate the first and / or second control commands based on the user's voice commands.

[0066] Optionally, in order to enable the first controller 20 to control the first motor 12 and the second motor 22, the first controller 20 may include a control unit 26 and a switching unit 28.

[0067] The switching unit 28 connects the first motor 12, the second motor 22, and the control unit 26. The control unit 26 is configured to control the switching unit 28 to control the first motor 12 to drive the winch 14. The control unit 26 is also configured to control the switching unit 28 to control the second motor 22. By controlling the switching unit 28, the control unit 26 can control the first motor 12 and the second motor 22.

[0068] Optionally, the second motor 22 and the first motor 12 can share the switching unit 28, which reduces the use of the switching unit 28 and lowers costs. The control unit can control the switching unit 28 to achieve synchronous control of the first motor 12 and the second motor 22. When the first motor 12 and the second motor 22 share the switching unit 28, the control unit 26 drives the first motor 12 and the second motor 22 to work simultaneously according to the control command. For example, the first motor 12 drives the winch 14 to operate, and the second motor 22 drives the first accessory 42 (such as the compressor) to operate. When the user turns on the winch 14 to reel in the cable, a control command is generated, and the control unit 26 controls the switching unit 28 to drive the first motor 12 and the second motor 22 to work simultaneously according to the control command. Ultimately, this achieves the winch 14 rotating to reel in the cable, while the air conditioner on the vehicle 200 operates simultaneously.

[0069] Optionally, the switching unit 28 includes a set of power module components. On the one hand, the set of power module components can drive the first motor 12 and the second motor 22 to work according to the control signal of the first controller 20; on the other hand, it can send the status signals of the first motor 12 and the second motor 22 back to the first controller 20, thereby enabling the first controller 20 to achieve closed-loop control of the first motor 12 and the second motor 22.

[0070] A set of power module components includes a first bridge arm 29, which connects a first motor 12 and a second motor 22, enabling the set of power module components to output voltages of different phases and use voltages of the same phase to synchronously control the first motor 12 and the second motor 22.

[0071] like Figure 2 As shown, the first bridge arm 29 connects the control unit 26 and the first motor 12 and the second motor 22.

[0072] The first motor 12 and the second motor 22 include, but are not limited to, high-voltage synchronous motors, high-voltage asynchronous motors, or high-voltage asynchronous wound-rotor motors, etc. Optionally, when the first motor 12 and the second motor 22 share the switching unit 28, the first motor 12 and the second motor 22 can be motors of the same type and model to improve the reliability of the motors.

[0073] Optionally, the control unit 26 is configured to control the first motor 12 and the second motor 22 to operate simultaneously according to control commands.

[0074] When the first motor 12 and the second motor 22 are operating simultaneously, the on / off state of the control switch unit 28 is used to control the first motor 12 and the second motor 22 to be in a synchronized state. The synchronized state can be, for example, phase synchronization of the first motor 12 and the second motor 22.

[0075] When the first motor 12 and the second motor 22 share the switching unit 28, the initial phases of the first motor 12 and the second motor 22 may be different. During startup, a smaller current is initially used to control the rotation of both motors. Once the first motor 12 and the second motor 22 reach a synchronized state, the required speed is then used to control their synchronized rotation to prevent damage to either motor 12 or the second motor 22. The synchronized state of the first motor 12 and the second motor 22 indicates that they operate in the same phase.

[0076] Optionally, Hall sensors are installed on the first motor 12 and the second motor 22 to detect the position of the motor rotor, thereby determining whether the first motor 12 and the second motor 22 have reached a synchronized state.

[0077] Optionally, the switching unit 28 includes a first switching unit and a second switching unit. The first switching unit is electrically connected to the first motor 12 and the control unit 26, and the control unit 26 is configured to control the first motor 12 to drive the winch 14 to operate. The second switching unit is electrically connected to the second motor 22 and the control unit 26, and the control unit 26 is configured to control the second switching unit to control the operation of the second motor 22. In this way, the on / off state and operating state of the first motor 12 and the second motor 22 can be controlled respectively.

[0078] For further details, please refer to [link / reference]. Figure 3 The first switching unit may include a first power module component 30, and the second switching unit may include a second power module component 32. The first power module component 30 can receive control signals from the first controller 20, drive the first motor 12 to operate, and send the status detection signal of the first motor 12 back to the first controller 20. The second power module component 32 can receive control signals from the first controller 20, drive the second motor 22 to operate, and send the status detection signal of the second motor 22 back to the first controller 20. The first power module component 30 and the second power module component 32 can respectively implement closed-loop control of the first motor 12 and the second motor 22 by the first controller 20.

[0079] like Figure 3 As shown, in some optional embodiments, both the first power module assembly 30 and the second power module assembly 32 include three bridge arms. The three bridge arms correspond to the U phase, V phase, and W phase, respectively. Each bridge arm is equipped with two IGBTs to control the on / off state of the U phase, V phase, and W phase of the first motor 12 and the second motor 22. The first power module assembly 30 and the second power module assembly can provide voltages of different phases to the first motor 12 and the second motor 22, respectively.

[0080] Optionally, the winch assembly 10 of the vehicle 200 also includes a second controller 34. The second controller 34 is electrically connected to the first controller 20. The second controller 34 is configured to send control commands to the first controller 20, causing the first controller 20 to control a motor, including a first motor 12, according to the control commands. The second controller 34 has the function of parsing and transmitting various information acquisition devices 37, bus data, and high- and low-frequency data. The communication methods between the second controller 34 and the first controller 20 include, but are not limited to, CAN (Controller Area Network), CANFD (CAN Flexible Data-rate), LIN (Local Interconnect Network), Ethernet, and other data communication protocols.

[0081] Optionally, the second controller 34 is the domain controller of the vehicle 200. The domain controller divides the entire vehicle into several domains such as powertrain, intelligent cockpit, and autonomous driving according to the functions of automotive electronic components. It uses multi-core CPU (Central Processing Unit) / GPU (Graphics Processing Unit) chips with stronger processing power to centrally control each domain, which has advantages such as platformization, compatibility, high integration, and good performance.

[0082] Optionally, the control commands include the motor's rotational speed and / or rotational direction. The second controller 34 is electrically connected to the first controller 20. The second controller 34 is configured to send control commands to the first controller 20. When the first controller 20 controls the first motor 12 and the second motor 22 respectively, the control commands may include a first control command and a second control command, wherein the first control command includes the rotational speed and rotational direction of the first motor 12, and the second control command includes the rotational speed and rotational direction of the second motor 22.

[0083] The second controller 34 connects to the data acquisition device 37 and the input component 36. The data acquisition device 37 includes, but is not limited to, vehicle temperature sensors, pressure sensors, solar radiation sensors, altitude sensors, slope sensors, etc. The data acquisition device 37 is used to acquire various signals from inside and outside the vehicle 200.

[0084] Optionally, the input component 36 may include a physical switch 38 disposed on the vehicle 200. The second controller 34 generates control commands based on the user's operation of the physical switch 38. For example, when the user presses the rope release button on the vehicle 200, the second controller 34 generates a first control command (including the speed and rotation angle of the first motor 12) and sends it to the first controller 20. The first controller controls the first motor 12 to operate according to the target speed and rotation angle in the first control command, so that the winch 14 releases the cable.

[0085] Optionally, the input component 36 may include a terminal device 40 that is communicatively connected to the vehicle 200. The terminal device 40 includes, but is not limited to, car keys, tablets, smartphones, wearable smart devices, etc. The user generates control commands through corresponding control switches on the terminal device 40.

[0086] Optionally, the second controller 34 is configured to generate control commands based on the output information of the acquisition device 37 and the output commands of the input component 36.

[0087] Optionally, the second controller 34 is configured to generate control commands based on the output commands of the input component 36.

[0088] For example, the vehicle 200 has a control switch for the winch 14. The control switch for the winch 14 includes a release button and a reel button. When the user presses the release button, the second controller 34 generates a control command based on the user's operation of the release button and sends the control command to the first controller 20. The first controller 20 drives the first motor 12 according to the control command, and the first motor 12 drives the winch 14 to rotate, releasing the cable.

[0089] The winch assembly 10 described above can achieve the following functions: The user operates the input component 36; for example, the user presses the soft button for the rope winding function on the winch 14 on the terminal device 40 (this operation can be a long press or a short press), and simultaneously turns on the vehicle's air conditioning switch and sets the air outlet temperature to 26°C. During the button's active period, the terminal device 40 sends an output command through a specific data communication protocol (such as a CAN bus), which is received by the second controller 34.

[0090] The second controller 34 determines the user's current needs for the winch 14 and air conditioning based on the output information of the input component 36, and controls the vehicle air conditioning and winch. For example, the temperature sensor of the acquisition device 37 acquires that the current outside temperature is 30°C and the inside temperature is 28°C, and the slope sensor of the acquisition device 37 acquires that the slope of the current location of the vehicle 200 is 30°. The second controller 34 calculates the compressor motor 24 speed (e.g., 3000 r / min) that can make the air conditioner outlet temperature reach the target outlet temperature, and the first motor 12 speed (e.g., 2000 r / min) required to make the vehicle 200 be pulled at a constant speed under the current slope (30°) based on the output information of the acquisition device 37 and the output instructions of the input component 36 (turning on the air conditioner switch and setting the target air outlet temperature to 26°, and the rope retraction control instruction). It generates a second control instruction (target speed of compressor motor 24 is 3000 r / min) and a first control instruction (target speed of first motor 12 is 2000 r / min), and sends the first control instruction and the second control instruction to the first controller 20 via the bus. The first controller 20 controls the compressor motor 24 to run at the target speed according to the second control instruction, and controls the first motor 12 to drive the winch 14 to run at the target speed according to the first control instruction.

[0091] Specifically, the first controller 20 can receive a first control command and a second control command, and control the corresponding IGBTs in the first switching unit and the second switching unit according to the first control command and the second control command, respectively, to provide high voltage electricity of different phases, so as to control the compressor motor 24 and the first motor 12 to run at the target speed.

[0092] Furthermore, to enhance the integration of the vehicle 200, the first motor 12 is also configured to drive the first accessory 42 of the vehicle 200. In one embodiment, the first motor 12 and the winch 14 are configured to be located in the front compartment 19 of the vehicle 200 for easy user access.

[0093] Typically, the compressor and compressor motor 24 of vehicle 200 are also located in the front compartment 19. The first motor 12 may include the compressor motor 24. Therefore, the winch 14 and the compressor can share the compressor motor 24, thereby saving installation space and weight for the winch 14. It is understood that the first accessory 42 may be any other functional component of vehicle 200 besides the winch 14, which can be driven by an electric motor.

[0094] Optionally, the first motor 12 is the compressor motor 24 of the vehicle 200. The first accessory 42 is a compressor. The compressor motor 24 of the vehicle 200 is generally installed near the front compartment 19 of the vehicle 200. When the winch 14 is installed in the front compartment 19 of the vehicle 200, the compressor motor 24 can be connected. Therefore, the compressor motor 24 that drives the compressor (first accessory 42) can be reused as the power source for driving the winch 14. The compressor motor 24 can be arranged close to the winch 14, resulting in a shorter transmission distance and better transmission effect.

[0095] The winch 14 is installed in the front compartment 19 of the vehicle 200. The first motor 12 includes a compressor motor 24 installed in the front compartment 19, and the first accessory 42 includes a compressor. In this way, the winch 14 and the compressor share a single high-voltage motor, saving installation space.

[0096] Optionally, the first motor 12 is the drive motor of the vehicle 200. The first accessory 42 is a wheel. Reusing the drive motor of the drive wheel (first accessory 42) can provide greater power to the winch.

[0097] like Figure 4 As shown, optionally, the winch assembly 10 of the vehicle 200 also includes a switching element 43.

[0098] Optionally, the switching element 43 is configured to connect the first motor 12 and the winch 14, and to connect the first motor 12 and the first accessory 42. In this way, the winch 14 and the first accessory 42 can share the first motor 12, and the first motor 12 can drive the winch 14 and the first accessory 42 to operate simultaneously, reducing costs.

[0099] Optionally, the switching element 43 is configured to connect the first motor 12 and the winch 14 or to connect the first motor 12 and the first accessory 42. Specifically, when the switching element 43 is configured to connect the first motor 12 and the winch 14, the first motor 12 can drive the winch 14 to run, and the first motor 12 is disconnected from the first accessory 42.

[0100] When the switching element 43 is configured to connect the first motor 12 and the first accessory 42, the first motor 12 can drive the first accessory 42 to run, and the first motor 12 is disconnected from the winch 14.

[0101] Optionally, the switching element 43 may include a clutch 44, which is disposed between the driving element and the driven element, and achieves selective power transmission by engaging or disengaging the driving element and the driven element.

[0102] The clutch 44 includes a first part 44a, a second part 44b, and a third part 44c. The first part 44a is connected to the rotating shaft of the winch 14. The second part 44b is connected to the first accessory 42, and the third part 44c is connected to the output shaft 16 of the first motor 12. When the first part 44a and the third part 44c are engaged, the second part 44b and the third part 44c are disengaged, and the first motor 12 is connected to the winch 14, enabling the first motor 12 to drive the winch 14.

[0103] When the first part 44a and the third part 44c are separated, the first motor 12 is disconnected from the winch 14. When the second part 44b and the third part 44c are engaged, the first part 44a and the third part 44c are separated, the first motor 12 is connected to the first accessory 42, and the first motor 12 can drive the first accessory 42 to operate, for example, drive the rotation mechanism of the first accessory to rotate. When the second part 44b and the third part 44c are separated, the first motor is disconnected from the first accessory 42.

[0104] With the third part 44c separated from the first part 44a and the second part 44b, the first motor 12 is disconnected from the winch 14 and from the first accessory 42.

[0105] Optionally, the switching element 43 may include a gearbox. For example, the gearbox may use multiple transmission elements to distribute and transmit power, allowing the output shaft 16 of the motor to be selectively connected to the rotating mechanism on the first accessory 42 or the rotating shaft of the winch 14.

[0106] Optionally, the winch assembly 10 of the vehicle 200 also includes a reducer 46. The reducer 46 is disposed between the driving member and the driven member or actuator, and serves to match the rotational speed and transmit torque. Using the reducer 46 can reduce the rotational speed and increase the torque, enabling the driven member to withstand greater loads and achieve higher working efficiency.

[0107] Optionally, the reducer 46 is configured to connect the switching element 43 and the first motor 12. Specifically, the reducer 46 connects the third part 44c and the output shaft 16 of the first motor 12. The speed of the first motor 12 is reduced by the reducer 46 and then output to the winch 14.

[0108] Optionally, the reducer 46 is configured to connect the winch 14 and the switching element 43. Specifically, the reducer 46 connects the first part 44a and the rotating shaft of the winch 14. The rotational speed of the first electric motor 12 is transmitted to the reducer 46 via the third part 44c and the first part 44a. After reduction, the reducer 46 outputs the speed to the rotating shaft of the winch 14.

[0109] In summary, by setting up the speed reducer 46, the rotational speed can be reduced while the torque is increased, allowing the winch 14 to withstand a greater load.

[0110] Optionally, the operating voltage of the first motor 12 is not less than 250 volts (V). This allows the first motor 12 to provide greater power to the first accessory 42 or the winch 14. Using a high-voltage motor avoids the winch 14 from shutting down due to overheating caused by excessive current from a low-voltage motor.

[0111] In some examples, the operating voltage of the first motor 12 can be 250V, 270V, 300V, 330V, 360V, 400V, 450V, 500V, 550V, 600V, or other voltages not less than 250V. The upper limit of the operating voltage of the first motor 12 can be set according to the actual situation, and is not specifically limited here.

[0112] In one embodiment, the operating voltage of the first motor 12 may be provided by the power battery 18 of the vehicle 200, which is a battery that drives the drive motor of the vehicle 200.

The first motor 12 is configured to drive the winch 14 using the power battery. The power battery 18 is a battery that drives the drive motor of the vehicle 200.

[0115] In the winch assembly 10 of the aforementioned vehicle 200, the first motor 12 can use the output voltage of the power battery 18 to drive the winch 14 to operate, thereby enabling the winch 14 to work continuously and improving the user experience.
