In order to simplify the disclosure of the embodiments of the present application, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present application. The embodiments of the present application may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the embodiments of the present application provide examples of various specific processes and materials, but those of ordinary skill in the art will appreciate the application of other processes and / or the use of other materials.

[0048] 1 and 5 , a vehicle 200 may be equipped with a winch 14 to assist in escaping a vehicle 200 or other vehicle 200. 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.

[0049] The winch 14 can be set in the front cabin 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 is used to drive the rotating shaft to rotate, driving the winch 14 to release and tighten the cable. Optionally, the winch 14 includes a reel, and the cable can be wound around the reel. The reel can be connected to the rotating shaft, and the cable can be tightened and released when the reel rotates.

[0050] In the related art, the winch 14 is driven by a hydraulic system. When the winch 14 works continuously, it is easy to stop working due to excessive temperature, causing the winch 14 to also stop working, resulting in rescue interruption and poor user experience.

[0051] In the embodiment of the present application, the first motor 12 and the winch 14 are configured to be installed in a 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. The power battery 18 is the battery that drives the drive motor of the vehicle 200. In this way, the first motor 12 can use the output voltage of the power battery 18 to drive the winch 14, thereby reducing the problem of the first motor 12 driving the winch 14 overheating during operation, thereby facilitating continuous operation of the winch 14 and improving the user experience. Specifically, the power battery 18 can be in the form of a battery pack or other forms of power battery.

[0052] It can be understood 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 can be reduced during operation, thereby reducing the heat generated by the first motor 12, so that the winch 14 can work continuously.

[0053] In some optional embodiments, the operating voltage of the first motor 12 is greater than 250V.

[0054] The winch 14 is connected to the first motor 12, which is powered by the power battery 18 of the vehicle 200. Using the power battery 18 to power the first motor 12 increases the operating voltage and reduces the operating current of the first motor 12, preventing the hydraulic system from overheating and potentially interrupting the rescue operation when the winch 14 is continuously operating. Furthermore, using the power battery 18 of the vehicle 200 to power the first motor 12 eliminates the need for a separate power source for the winch assembly 10, saving installation space and manufacturing costs.

[0055] 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 is configured to utilize 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) having bus data parsing, calculation, and driving functions. The first controller 20 is also connected to a power supply unit 21, which is electrically connected to the first controller 20 and configured to supply power to the first controller 20.

[0056] 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 storage module configured on the vehicle 200 itself, or a separately provided low-voltage battery, which is electrically connected to the first controller 20.

[0057] Optionally, the first controller 20 is further configured to control the operation of a second motor 22. The second motor 22 may be a motor that drives other accessories on the vehicle 200. The first controller 20 controls the rotation of the first motor 12 and the second motor 22, thereby reducing the number of controllers used and lowering the cost of the vehicle 200.

[0058] Alternatively, the second motor 22 may be the compressor motor 24 of the vehicle 200 . In this manner, the first controller 20 can control the operation of the compressor motor 24 of the vehicle 200 to drive the compressor. The first controller 20 can also control the operation of the first motor 12 to drive the winch, for example, to tighten or loosen the winch 14 . The first motor 12 and the compressor motor 24 may share the first controller 20 . This reduces the number of controllers used and lowers the cost of the vehicle 200 .

[0059] Furthermore, the first controller 20 is configured to control the operation of the first motor 12 according to a first control instruction and to control the operation of the second motor 22 according to a second control instruction. The first control instruction and the second control instruction are generated by a user according to user requirements or according to instructions of the high voltage system 100.

[0060] Optionally, the first control instruction and the second control instruction may be generated through a physical switch 38. The physical switch 38 may be in the form of a knob switch, a push button switch, a sliding switch, etc., which are provided in the vehicle 200. The first controller 20 is connected to the physical switch 38, and the user generates the first control instruction and the second control instruction by operating the physical switch 38. In one example, the first control instruction may be an instruction to control the winch 14 to tighten the cable, and in one example, the first control instruction 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 instruction may be an instruction to control the vehicle air conditioner to turn on, so that the compressor motor 24 turns on at a target speed.

[0061] Optionally, the first control instruction and the second control instruction may be generated by a virtual switch. The virtual switch may include a virtual switch displayed on a display component of the vehicle 200, and the user may operate (long press or short press, etc.) the virtual switch of the winch 14 through the display component of the vehicle to generate the first control instruction.

[0062] Furthermore, the first controller 20 can be communicatively connected to a user's terminal device 40, which includes but is not limited to a car key, a tablet computer, a smart phone, a wearable smart device, etc. The user generates a first control instruction and / or a second control instruction through corresponding control switches on the terminal device 40.

[0063] Optionally, the first control instruction and the second control instruction may be generated by voice commands. The first controller 20 is connected to a voice component on the vehicle 200, which can collect user voice commands, so that the first controller 20 can generate the first control instruction and / or the second control instruction based on the user's voice commands.

[0064] Optionally, in order to implement 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 switch unit 28 .

[0065] The switch unit 28 is connected to the first motor 12, the second motor 22, and the control unit 26. The control unit 26 is configured to control the switch unit 28 to control the first motor 12 to drive the winch 14. The control unit 26 is also configured to control the switch unit 28 to control the second motor 22. The control unit 26 controls the switch unit 28 to control the first motor 12 and the second motor 22.

[0066] Optionally, the second motor 22 and the first motor 12 may share a switch unit 28, which can reduce the use of the switch unit 28 and reduce costs. The control unit can control the switch 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 switch unit 28, the control unit 26 drives the first motor 12 and the second motor 22 to work simultaneously according to the control instruction. For example, the first motor 12 drives the winch 14 to operate, and the second motor 22 drives the first accessory 42 (such as a compressor) to operate. When the user turns on the winch 14 rope retraction switch, a control instruction is generated, and the control unit 26 controls the switch unit 28 to drive the first motor 12 and the second motor 22 to work simultaneously according to the control instruction. Ultimately, the winch 14 rotates to retract the cable, and the air conditioner on the vehicle 200 runs at the same time.

[0067] Optionally, the switch unit 28 includes a set of power module assemblies. The set of power module assemblies can, on the one hand, drive the first motor 12 and the second motor 22 according to control signals from the first controller 20, and on the other hand, send 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 implement closed-loop control of the first motor 12 and the second motor 22.

[0068] A group of power module components includes a first bridge arm 29, which connects the first motor 12 and the second motor 22, so that the group of power module components can output voltages of different phases and use the same phase voltage to synchronously control the first motor 12 and the second motor 22.

[0069] As shown in FIG. 2 , the first bridge arm 29 connects the control unit 26 and the first motor 12 and the second motor 22 .

[0070] The first motor 12 and the second motor 22 include, but are not limited to, a high-voltage synchronous motor, a high-voltage asynchronous motor, or a high-voltage asynchronous wound-rotor motor. Optionally, if the first motor 12 and the second motor 22 share a switching unit 28, the first motor 12 and the second motor 22 may be motors of the same type and model to improve motor reliability.

[0071] Optionally, the control unit 26 is configured to control the first motor 12 and the second motor 22 to operate simultaneously according to the control instruction.

[0072] When the first motor 12 and the second motor 22 are in operation simultaneously, the switch unit 28 is controlled to be on and off to synchronize the first motor 12 and the second motor 22. The synchronization state may be, for example, phase synchronization of the first motor 12 and the second motor 22.

[0073] When the first motor 12 and the second motor 22 share the switch unit 28, the first motor 12 and the second motor 22 may initially have different phases. Therefore, during startup, the first motor 12 and the second motor 22 need to be controlled to rotate at a relatively low current. After the first motor 12 and the second motor 22 reach a synchronous state, the first motor 12 and the second motor 22 are controlled to rotate synchronously at the speed specified in the first control instruction or the second control instruction to prevent damage to the first motor 12 or the second motor 22. The synchronous state of the first motor 12 and the second motor 22 indicates that the first motor 12 and the second motor 22 are operating in the same phase.

[0074] Optionally, Hall sensors are provided on the first motor 12 and the second motor 22 to detect the positions of the motor rotors, thereby determining whether the first motor 12 and the second motor 22 have reached a synchronous state.

[0075] Optionally, the switch unit 28 includes a first switch unit and a second switch unit. The first switch unit is electrically connected to the first motor 12 and the control unit 26. The control unit 26 is configured to control the first motor 12 to drive the winch 14. The second switch unit is electrically connected to the second motor 22 and the control unit 26. The control unit 26 is configured to control the second switch unit to control the operation of the second motor 22. In this way, the power on and off states and operating states of the first motor 12 and the second motor 22 can be controlled separately.

[0076] Further, referring to FIG3 , the first switch unit may include a first power module assembly 30, and the second switch unit may include a second power module assembly 32. The first power module assembly 30 can receive control signals from the first controller 20, drive the first motor 12 to operate, and send a status detection signal of the first motor 12 back to the first controller 20. The second power module assembly 32 can receive control signals from the first controller 20, drive the second motor 22 to operate, and send a status detection signal of the second motor 22 back to the first controller 20. The first power module assembly 30 and the second power module assembly 32 can respectively implement closed-loop control of the first motor 12 and the second motor 22 by the first controller 20.

[0077] As shown in FIG3 , in some optional embodiments, the first power module assembly 30 and the second power module assembly 32 each include three bridge arms. The three bridge arms correspond to the U phase, the V phase, and the W phase, respectively. Each bridge arm is equipped with two IGBTs to control the on / off states of the U phase, the V phase, and the 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 respectively provide voltages of different phases to the first motor 12 and the second motor 22.

[0078] Optionally, the winch assembly 10 of the vehicle 200 further 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 instructions to the first controller 20 so that the first controller 20 controls the motor according to the control instructions, and the motor includes the first motor 12. 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 method between the second controller 34 and the first controller 20 includes but is not limited to CAN (Controller Area Network), CANFD (CAN Flexible Data-rate), LIN (Local Interconnect Network), Ethernet and other data communication protocols.

[0079] Optionally, the second controller 34 is a domain controller for the vehicle 200. The domain controller divides the vehicle into several domains, such as powertrain, smart cockpit, and autonomous driving, based on the functions of the vehicle's electronic components. It utilizes a multi-core CPU (Central Processing Unit) / GPU (Graphic Processing Unit) chip with greater processing power to centrally control each domain, offering advantages such as platformization, compatibility, high integration, and high performance.

[0080] Optionally, the control instructions include the speed and / or rotation direction of the motor. The second controller 34 is electrically connected to the first controller 20. The second controller 34 is configured to send control instructions to the first controller 20. When the first controller 20 controls the first motor 12 and the second motor 22, respectively, the control instructions may include a first control instruction and a second control instruction, wherein the first control instruction includes the speed and rotation direction of the first motor 12, and the second control instruction includes the speed and rotation direction of the second motor 22.

[0081] The second controller 34 is connected to a collection device 37 and an input component 36. The collection device 37 includes, but is not limited to, a vehicle temperature sensor, a pressure sensor, a sunlight radiation sensor, an altitude sensor, a slope sensor, etc. The collection device 37 is used to collect various signals from inside and outside the vehicle 200.

[0082] Optionally, the input component 36 may include a physical switch 38 provided on the vehicle 200. The second controller 34 generates a control instruction based on the user's operation of the physical switch 38. For example, when the user presses the rope-releasing button on the vehicle 200, the second controller 34 generates a first control instruction (including the speed and rotation angle of the first motor 12) and sends it to the first controller 20. The first controller controls the operation of the first motor 12 at the target speed and rotation angle specified in the first control instruction, causing the winch 14 to release the cable.

[0083] 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, a car key, a tablet computer, a smartphone, a wearable smart device, etc. The user generates a control instruction through a corresponding control switch on the terminal device 40.

[0084] Optionally, the second controller 34 is configured to generate a control instruction according to the output information of the acquisition device 37 and the output instruction of the input component 36 .

[0085] Optionally, the second controller 34 is configured to generate a control instruction according to an output instruction of the input component 36 .

[0086] For example, vehicle 200 includes control switches for winch 14. These switches include a release button and a reel button. When a user presses the release button, second controller 34 generates a control instruction based on the user's operation and sends the instruction to first controller 20. First controller 20 then drives first motor 12 according to the control instruction, which in turn rotates winch 14, releasing the cable.

[0087] The winch assembly 10 can implement the following functions: a user operates the input component 36, for example, the user presses the winch 14 retraction function soft key on the terminal device 40 (the operation here can be a long press or a short press), and at the same time, the user turns on the vehicle's air conditioner and sets the air temperature to 26°C. While the key is active, the terminal device 40 sends an output command via a specific data communication protocol (such as a CAN bus), which is received by the second controller 34.

[0088] The second controller 34 determines the user's demand for the winch 14 and the air conditioner at this time based on the output information of the input component 36, and controls the vehicle air conditioner and the winch. For example, the temperature sensor of the acquisition device 37 detects that the current temperature outside the vehicle is 30°C and the temperature inside the vehicle is 28°C. The slope sensor of the acquisition device 37 detects that the slope of the current position of the vehicle 200 is 30°. The second controller 34 calculates the speed of the compressor motor 24 (for example, 3000 r / min) that can make the air outlet temperature of the air conditioner reach the target air outlet temperature, and the speed of the first motor 12 (for example, 2000 r / min) required for the vehicle 200 to be pulled at a uniform speed when the vehicle 200 is at 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 on the vehicle and setting the target air outlet temperature of the air conditioner to 26°C, and the rope retraction control instruction), and generates a second control instruction (the target speed of the compressor motor 24 is 3000 r / min) and a first control instruction (the target speed of the first motor 12 is 2000 r / min), and sends the first control instruction and the second control instruction to the first controller 20 through the bus. The first controller 20 controls the operation of the compressor motor 24 according to the second control instruction, so that the compressor motor 24 runs at the target speed, and controls the first motor 12 to drive the winch 14 to run according to the first control instruction, so that the first motor 12 runs at the target speed.

[0089] Specifically, the first controller 20 can receive the first control instruction and the second control instruction, and control the corresponding IGBTs in the first switch unit and the second switch unit according to the first control instruction and the second control instruction, respectively, to provide high voltage electricity of different phases to respectively control the compressor motor 24 and the first motor 12 to operate at the target speed.

[0090] Furthermore, to enhance the integration of the vehicle 200, the first motor 12 is further 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 disposed in the front cabin 19 of the vehicle 200 for user convenience.

[0091] Typically, the compressor and compressor motor 24 of vehicle 200 are also located in front compartment 19. The first motor 12 may include the compressor motor 24. Therefore, the winch 14 and the compressor may share the compressor motor 24, thereby saving installation space and weight for the winch 14. It will be appreciated that the first accessory 42 may be any other functional component of vehicle 200 besides the winch 14, which may be driven by a motor.

[0092] 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 cabin 19 of the vehicle 200. When the winch 14 is installed in the front cabin 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 placed in close proximity to the winch 14, ensuring a shorter transmission distance and better transmission efficiency.

[0093] The winch 14 is mounted on the front cabin 19 of the vehicle 200. The first motor 12 includes a compressor motor 24 mounted on the front cabin 19. The first accessory 42 includes a compressor. In this way, the winch 14 and the compressor share a high-voltage motor, saving installation space.

[0094] Optionally, the first motor 12 is a drive motor of the vehicle 200. The first accessory 42 is a wheel. Reusing the drive motor of the drive wheel (the first accessory 42) can provide greater power for the winch.

[0095] As shown in FIG. 4 , optionally, the winch assembly 10 of the vehicle 200 further includes a switching member 43 .

[0096] Optionally, the switching member 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 at the same time, thereby reducing costs.

[0097] Optionally, the switching member 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 member 43 is configured to connect the first motor 12 and the winch 14, the first motor 12 can drive the winch 14 to operate, and the first motor 12 is disconnected from the first accessory 42.

[0098] When the switching member 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 operate, and the first motor 12 is disconnected from the winch 14 .

[0099] Optionally, the switching member 43 may include a clutch 44 , which is disposed between the active member and the driven member, and realizes selective power transmission by combining or separating the active member and the driven member.

[0100] The clutch 44 includes a first portion 44a, a second portion 44b, and a third portion 44c. The first portion 44a is connected to the rotating shaft of the winch 14. The second portion 44b is connected to the first accessory 42, and the third portion 44c is connected to the output shaft 16 of the first motor 12. When the first portion 44a and the third portion 44c are engaged, the second portion 44b and the third portion 44c are separated, and the first motor 12 is connected to the winch 14, so that the first motor 12 can drive the winch 14 to operate.

[0101] When the first portion 44a is separated from the third portion 44c, the first motor 12 is disconnected from the winch 14. When the second portion 44b is engaged with the third portion 44c, the first portion 44a and the third portion 44c are separated, and the first motor 12 is connected to the first accessory 42. The first motor 12 can drive the first accessory 42 to operate, such as driving the rotating mechanism of the first accessory to rotate. When the second portion 44b and the third portion 44c are separated, the first motor is disconnected from the first accessory 42.

[0102] When the third portion 44 c is separated from both the first portion 44 a and the second portion 44 b , the first motor 12 is disconnected from the winch 14 and the first accessory 42 .

[0103] Optionally, the switching member 43 may include a gearbox. For example, the gearbox may utilize multiple transmission members to distribute and transmit power, so that the output shaft 16 of the motor can be selectively connected to the rotating mechanism on the first accessory 42 or the rotating shaft of the winch 14.

[0104] Optionally, the winch assembly 10 of the vehicle 200 further includes a speed reducer 46. The speed reducer 46 is disposed between the driving member and the driven member or actuator, and functions to match rotational speeds and transmit torque. The speed reducer 46 can reduce rotational speed and increase torque, enabling the driven member to withstand greater loads and achieve higher operating efficiency.

[0105] Optionally, the reducer 46 is configured to connect the switching member 43 and the first motor 12 , specifically, the reducer 46 connects the third portion 44 c 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 .

[0106] Optionally, a speed reducer 46 is configured to connect the winch 14 and the switching member 43. Specifically, the speed reducer 46 connects the first portion 44a and the rotating shaft of the winch 14. The rotational speed of the first motor 12 is transmitted to the speed reducer 46 via the third portion 44c and the first portion 44a. The speed reducer 46 reduces the speed and outputs it to the rotating shaft of the winch 14.

[0107] In summary, the provision of the speed reducer 46 can reduce the rotational speed while increasing the torque, so that the winch 14 can withstand a greater load.

[0108] 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 can prevent a low-voltage motor from overheating due to excessive current, which could cause the winch 14 to suspend operation.

[0109] In some examples, the operating voltage of the first motor 12 can be 250 V, 270 V, 300 V, 330 V, 360 V, 400 V, 450 V, 500 V, 550 V, 600 V, or other voltages not less than 250 V. The upper limit of the operating voltage of the first motor 12 can be set according to actual conditions and is not specifically limited here.

[0110] In one embodiment, the operating voltage of the first motor 12 may be provided by the power battery 18 of the vehicle 200 , where the power battery 18 is a battery that drives the drive motor of the vehicle 200 .
