[0050] See also Figure 1 and Figure 5 The vehicle 200 may 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, which includes a first motor 12 and a winch 14, and the power battery 18 is electrically connected to the first motor 12.

[0051] The winch 14 can be arranged 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.

[0052] 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 over-high temperature, causing the winch 14 to also stop working, resulting in rescue interruption and poor user experience.

[0053] In the embodiment of the present application, the first motor 12 and the winch 14 are configured to be arranged in the vehicle 200, the first motor 12 is connected to the winch 14, the first motor 12 is configured to be electrically connected to the power battery 18 of the vehicle 200, and the first motor 12 is configured to drive the winch 14 to operate using the power battery 18, and the power battery 18 is a battery that drives the driving motor of the vehicle 200 to operate. In this way, the first motor 12 can drive the winch 14 to operate using the output voltage of the power battery 18, improve the phenomenon of the first motor 12 driving the winch 14 being too high when working, and then facilitate the continuous operation of the winch 14 and improve the user experience. Specifically, the power battery 18 can be in the form of a battery pack, or other forms of power batteries.

[0054] 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.

[0055] In some optional 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 supply power to the first motor 12 can, on the one hand, increase the working voltage of the first motor 12, reduce the working current of the first motor 12, and prevent the hydraulic system from stopping working due to excessive temperature when the winch 14 is working continuously, resulting in interruption of rescue. On the other hand, using the power battery 18 on the vehicle 200 to supply power to the first motor 12 eliminates the need to configure an additional power supply for the winch assembly 10, which can save installation space and manufacturing costs.

[0057] Optionally, in order 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 the first controller 20 is configured to control the first motor 12 to drive the winch 14 to operate using the output voltage of the power battery 18. 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.

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

[0059] Optionally, the first controller 20 is further configured to control the operation of the second motor 22. The second motor 22 may be a motor for driving other accessories on the vehicle 200. The first controller 20 controls the rotation of the first motor 12 and the second motor 22, which can reduce the number of controllers used and reduce the cost of the vehicle 200.

[0060] Alternatively, the second motor 22 may be a compressor motor 24 of the vehicle 200. In this way, the first controller 20 may control the operation of the compressor motor 24 of the vehicle 200 to drive the compressor to operate, and the first controller 20 may also control the operation of the first motor 12 to drive the winch to operate, such as causing the winch 14 to tighten or release a cable. The first motor 12 and the compressor motor 24 may share the first controller 20. In this way, the number of controllers used may be reduced, thereby reducing the cost of the vehicle 200.

[0061] Further, the first controller 20 is configured to control the first motor 12 to operate according to the first control instruction, and to control the second motor 22 to operate according to the second control instruction. The first control instruction and the second control instruction are generated by user operation according to user requirements or according to instructions of the high voltage system 100.

[0062] Optionally, the first control instruction and the second control instruction may be generated by 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 arranged 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 be turned on, so that the compressor motor 24 is turned on at a target speed.

[0063] 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.

[0064] Furthermore, the first controller 20 can be connected to the user's terminal device 40 for communication, and the terminal device 40 includes but is not limited to a car key, a tablet computer, a smart phone, a wearable smart device, etc. The user generates the first control instruction and / or the second control instruction through the corresponding control switch on the terminal device 40.

[0065] Optionally, the first control instruction and the second control instruction may be generated by voice instructions. The first controller 20 is connected to a voice component on the vehicle 200, and the voice component may collect user voice instructions, so that the first controller 20 may generate the first control instruction and / or the second control instruction according to the user's voice instructions.

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

[0067] 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 to operate. The control unit 26 is also configured to control the switch unit 28 to control the second motor 22 to operate. The control unit 26 controls the switch unit 28 to control the first motor 12 and the second motor 22.

[0068] 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 retracting 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. Finally, the winch 14 rotates to retract the cable, and the air conditioner on the vehicle 200 is running at the same time.

[0069] Optionally, the switch unit 28 includes a group of power module components. The group of power module components can, on the one hand, 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, send the state signal of the first motor 12 and the second motor 22 back to the first controller 20, so that the first controller 20 can achieve closed-loop control of the first motor 12 and the second motor 22.

[0070] 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.

[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 a high voltage synchronous motor, a high voltage asynchronous motor or a high voltage asynchronous wound rotor motor, etc. Optionally, when the first motor 12 and the second motor 22 share a switch 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 run simultaneously according to the control instruction.

[0074] When the first motor 12 and the second motor 22 are in a state of simultaneous operation, the switch unit 28 is controlled to be in a synchronous state. The synchronous state may be, for example, phase synchronization of the first motor 12 and the second motor 22 .

[0075] In the case where the first motor 12 and the second motor 22 share the switch unit 28, the initial phases of the first motor 12 and the second motor 22 may be different. When starting, it is necessary to first control the first motor 12 and the second motor 22 to rotate with a smaller current, wait for the first motor 12 and the second motor 22 to run to a synchronous state, and then control the first motor 12 and the second motor 22 to rotate synchronously at the speed required 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 means that the first motor 12 and the second motor 22 run in the same phase.

[0076] Optionally, Hall sensors are provided on the first motor 12 and the second motor 22 to detect the positions of the motor rotors, so as to determine whether the first motor 12 and the second motor 22 have reached a synchronous state.

[0077] 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, and the control unit 26 is configured to control the first motor 12 to drive the winch 14 to operate. The second switch 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 switch unit to control the operation of the second motor 22. In this way, the power on and off states and the working states of the first motor 12 and the second motor 22 can be controlled respectively.

[0078] For further information, see Figure 3 , 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 may receive a control signal from the first controller 20, drive the first motor 12 to operate, and send a state detection signal of the first motor 12 back to the first controller 20. The second power module assembly 32 may receive a control signal from the first controller 20, drive the second motor 22 to operate, and send a state 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 may respectively implement closed-loop control of the first controller 20 on the first motor 12 and the second motor 22.

[0079] like Figure 3 As shown, 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 provided 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 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 a control instruction to the first controller 20 so that the first controller 20 controls the motor according to the control instruction, 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), CAN FD (CAN Flexible Data-rate), LIN (Local Interconnect Network), Ethernet and other data communication protocols.

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

[0082] Optionally, the control instruction includes 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 a control instruction to the first controller 20. When the first controller 20 controls the first motor 12 and the second motor 22 respectively, the control instruction may include a first control instruction and a second control instruction, 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.

[0083] The second controller 34 is connected to the collection device 37 and the input component 36. The collection device 37 includes but is not limited to the vehicle's temperature sensor, pressure sensor, sunlight radiation sensor, height sensor, slope sensor, etc. The collection device 37 is used to collect various signals 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 a control instruction according to the user's operation on 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 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 with the target speed and rotation angle in the first control instruction, 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 a car key, a tablet computer, a smart phone, a wearable smart device, etc. The user generates a control instruction through a corresponding control switch on the terminal device 40.

[0086] 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 .

[0087] Optionally, the second controller 34 is configured to generate a control instruction according to an output instruction 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 rope-releasing button and a rope-collecting button. When the user presses the rope-releasing button, the second controller 34 generates a control instruction according to the user's operation on the rope-releasing button, and sends the control instruction to the first controller 20. The first controller 20 drives the first motor 12 according to the control instruction, and the first motor 12 drives the winch 14 to rotate and release the cable.

[0089] The winch assembly 10 can realize the following functions: the user operates on the input component 36, for example, the user presses the soft key of the winch 14 rope collection function on the terminal device 40 (the operation here can be a long press or a short press), and the user turns on the air conditioner switch on the car and sets the air outlet temperature of the air conditioner to 26° C. During the effective period of the key, the terminal device 40 sends an output command through a specific data communication protocol (such as a CAN bus), and the second controller 34 receives it.

[0090] The second controller 34 determines the user's demand for the winch 14 and the air conditioner 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 that can make the air outlet temperature of the air conditioner reach the target air outlet temperature (for example, 3000r / min) and the speed of the first motor 12 (for example, 2000r / 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 conditioning switch on the vehicle and setting the target air outlet temperature of the air conditioner to 26°C, and the rope retracting control instruction), and generates the second control instruction (the target speed of the compressor motor 24 is 3000r / min) and the first control instruction (the target speed of the first motor 12 is 2000r / 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.

[0091] 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 run at the target speed.

[0092] Further, in order to improve 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 disposed in the front cabin 19 of the vehicle 200 for user convenience.

[0093] Typically, the compressor and the compressor motor 24 of the vehicle 200 are also disposed in the front cabin 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 the installation space of the winch 14 and the weight of the winch 14. It is understood that the first accessory 42 may be any other functional component of the vehicle 200 except the winch 14, and the functional component may be driven and operated by a motor.

[0094] Optionally, the first motor 12 is a 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 at a position of the vehicle 200 close to the front cabin 19, and 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 a power source for driving the winch 14. The compressor motor 24 can be arranged close to the winch 14, so that the transmission distance is short and the transmission effect is good.

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

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

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

[0098] 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.

[0099] 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.

[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 operate, and the first motor 12 is disconnected from the winch 14 .

[0101] 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.

[0102] The clutch 44 includes a first portion 44a, a second portion 44b, and a third portion 44c, wherein 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 is coupled to the third portion 44c, the second portion 44b and the third portion 44c are separated, and the first motor 12 is connected to the winch 14, and the first motor 12 can drive the winch 14 to operate.

[0103] When the first part 44a is separated from the third part 44c, the first motor 12 is disconnected from the winch 14. When the second part 44b is engaged with the third part 44c, the first part 44a is separated from the third part 44c, 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 part 44b is separated from the third part 44c, the first motor is disconnected from the first accessory 42.

[0104] 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 .

[0105] Optionally, the switching member 43 may include a gearbox. For example, the gearbox may use a plurality of 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.

[0106] Optionally, the winch assembly 10 of the vehicle 200 further includes a reducer 46. The reducer 46 is disposed between the active member and the driven member or the actuator to match the rotation speed and transmit the torque. The use of the reducer 46 can reduce the rotation speed and increase the torque, so that the driven member can bear a larger load and have a higher working efficiency.

[0107] 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 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 member 43, specifically, the reducer 46 connects the first part 44a and the rotating shaft of the winch 14. The rotation speed of the first motor 12 is transmitted to the reducer 46 via the third part 44c and the first part 44a, and the reducer 46 outputs the speed to the rotating shaft of the winch 14 after deceleration.

[0109] In summary, by providing the reducer 46, the rotation speed can be reduced while the torque is increased, so that the winch 14 can withstand a greater load.

[0110] Optionally, the working voltage of the first motor 12 is not less than 250 volts (V), so that the first motor 12 can provide more power to the first accessory 42 or the winch 14. Using a high-voltage motor can avoid the low-voltage motor causing overheating protection due to excessive current, which may cause the winch 14 to stop working.

[0111] In some examples, the operating voltage of the first motor 12 may 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 may be set according to actual conditions and is not specifically limited herein.

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