Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular to a trailer hook device and a control method thereof, an electronic device, a storage medium and a vehicle. Background Art

[0002] As the number of cars increases, the functions of cars are becoming more and more diversified. Vehicles are usually equipped with trailers, which can tow luggage carts to move with the vehicle or tow stranded vehicles to a safe area.

[0003] The trailer device generally includes a trailer hitch arranged in front of the vehicle and a trailer hook arranged at the rear of the vehicle. The trailer hook can be used to connect with the trailer hitch of the towed object so that the vehicle can tow the towed vehicle to move.

[0004] However, since the towed object cannot control its direction autonomously, it will swing irregularly during driving, thus affecting the driving posture and comfort of the main vehicle. Summary of the invention

[0005] The object of the present invention is to provide a trailer hook device and a control method thereof, an electronic device, a storage medium and a vehicle, aiming to solve the problem of vehicle shaking caused by the towed object during towing.

[0006] In order to achieve the above object, the present invention adopts the following technical scheme:

[0007] In a first aspect, the present application provides a trailer hook device, which may include a trailer hook assembly and a drive assembly, wherein the trailer hook assembly is suitable for being movably connected to a vehicle, and the drive assembly is suitable for driving the trailer hook assembly to move relative to the vehicle to reduce the vibration of the vehicle during towing.

[0008] The trailer hook device provided in the present application can drive the trailer hook assembly to move relative to the vehicle through a driving assembly to offset the impact of the swing of the towed object on the vehicle, thereby reducing the shaking of the vehicle and improving the driving comfort of the vehicle.

[0009] In some embodiments, the trailer hook assembly may be adapted to be movably connected to the vehicle along the width direction of the vehicle, and the drive assembly may be adapted to drive the trailer hook assembly to move relative to the vehicle along the width direction of the vehicle to reduce the shaking of the vehicle along the width direction.

[0010] In this way, during the towing process, the interference of the swing of the towed object on the vehicle along the width direction can be reduced, thereby reducing the shaking of the vehicle and improving the driving experience.

[0011] In some embodiments, the trailer hook device may further include a crossbeam, which may be adapted to be fixed to the vehicle and extend along the width direction of the vehicle, and the drive assembly may be adapted to drive the trailer hook assembly to move along the crossbeam.

[0012] In this way, the crossbeam can provide a guiding function for the trailer hook assembly, allowing the trailer hook assembly to move relative to the crossbeam to offset the swing of the towed object, thereby reducing the shaking of the vehicle.

[0013] In some embodiments, the trailer hook assembly may include a sliding member and a trailer hook connected to the sliding member, wherein the sliding member is slidably connected to the crossbeam, and the driving assembly is connected to the sliding member, and the driving assembly is suitable for driving the sliding member to slide along the crossbeam and drive the trailer hook to move along the crossbeam.

[0014] In this way, the driving assembly can drive the sliding member to slide along the crossbeam and drive the trailer hook to move along the crossbeam, thereby offsetting the swing of the towed object and reducing the shaking of the vehicle.

[0015] In some embodiments, the trailer hook assembly may further include a switching member, which may be connected between the sliding member and the trailer hook, and the switching member may allow the trailer hook to switch between a deployed state and a stowed state relative to the sliding member.

[0016] When the sliding member is in the unfolded state, the trailer hook can be used to connect with the towed object so as to drag the towed object to move along with the movement of the vehicle; when the towed object is not needed to be towed, the switching member can switch the towed object to the stowed state. In this way, the trailer hook can be stowed when not in use, thereby making the vehicle more beautiful and preventing the trailer hook from being exposed and causing increased damage to the vehicle when the vehicle collides.

[0017] In some embodiments, the trailer hook may include a connecting arm and a trailer part, the two ends of the connecting arm in the extension direction are respectively a first end and a second end, the first end is connected to the switching member, and the trailer part is arranged at the second end; when the trailer hook is in the extended state, the extension direction of the connecting arm intersects with the cross beam, and when the trailer hook is in the stowed state, the extension direction of the connecting arm is parallel to the cross beam.

[0018] When the trailer hook is in the extended state, the extension direction of the connecting arm intersects with the crossbeam, which can increase the distance between the crossbeam and the trailer part; when the trailer hook is in the stowed state, the extension direction of the connecting arm is parallel to the crossbeam, which can make the vehicle appearance more beautiful and prevent the trailer hook from protruding from the crossbeam, causing increased damage to the vehicle when a vehicle collision occurs.

[0019] In some embodiments, the switching member may be a rotating member, and the switching member allows the trailer hook to rotate relative to the sliding member between the deployed state and the stored state.

[0020] In this way, the trailer hook can rotate relative to the sliding member, so that the trailer hook can be flexibly switched between the deployed state and the stored state by rotating, and the operation is simple and convenient.

[0021] In some embodiments, the trailer hook assembly may further include a locking structure for locking the trailer hook to keep the trailer hook in an extended state.

[0022] In this way, when the trailer hook needs to tow the towed object, the locking structure can lock the trailer hook to keep the trailer hook in the deployed state, thereby preventing the trailer hook from rotating between the deployed state and the stowed state to cause the towed object to swing.

[0023] In some embodiments, the trailer hook device may further include a storage box, and the driving assembly is further used to drive the trailer hook to slide along the cross beam into the storage box, and when the trailer hook is located in the storage box, the trailer hook is in a storage state.

[0024] In this way, when the vehicle does not need to perform a towing task, the trailer hook is in a storage state. By providing the storage box, the trailer hook can be hidden at the bottom of the vehicle, thereby increasing the aesthetics of the vehicle.

[0025] In some embodiments, the storage box may include a first side wall and a second side wall that are opposite and spaced apart, and a storage space is formed between the first side wall and the second side wall. Before the trailer hook enters the storage box, the trailer hook is in the deployed position, the direction in which the first end points to the second end is consistent with the direction in which the first side wall points to the second side wall, and along the extension direction of the cross beam, the storage space is opposite to the first end, and when the driving assembly drives the trailer hook to slide along the cross beam toward the storage space, the second side wall squeezes the connecting arm to rotate the trailer hook from the deployed position to the storage position.

[0026] The storage space can be used to store the trailer hook. In this way, when the driving component drives the trailer hook to slide along the cross beam toward the storage space, the driving component drives the sliding member to slide into the storage space. Since the trailer hook is in the deployed state, the trailer hook cannot directly enter the storage space. The second side wall applies an extrusion force to the connecting arm, which can rotate the rotating member, thereby rotating the trailer hook from the deployed position to the storage position.

[0027] In some embodiments, before the trailer hook enters the storage box, the end of the first side wall facing the trailer hook is the third end, and the end of the second side wall facing the trailer hook is the fourth end; a first guide surface is provided between the inner wall surface of the first side wall and the end surface of the third end, and a second guide surface is provided between the inner wall surface of the second side wall and the end surface of the fourth end.

[0028] In this way, when the trailer hook enters the storage space, the first guide surface and the second guide surface can guide the trailer hook, thereby making the trailer hook enter the storage space more smoothly and avoiding the angle between the inner wall surface of the second side wall and the end face of the fourth end from blocking and damaging the trailer hook.

[0029] In some embodiments, the storage box may also include a bottom wall connected between the first side wall and the second side wall; before the trailer hook enters the storage box, the end of the bottom wall facing the trailer hook is the fifth end, and the end of the bottom wall away from the trailer hook is the sixth end; from the fifth end to the sixth end, the inner wall surface of the bottom wall gradually extends upward.

[0030] When the trailer hook enters the storage box, as the inner wall surface of the bottom wall gradually extends upward, the trailer hook is gradually lifted upward. In this way, the gap between the trailer hook and the ground can be increased, thereby preventing the trailer hook from hooking foreign objects during driving and causing interference with the driving process.

[0031] In a second aspect, the present application also provides a control method for a trailer hook device, which may include: acquiring motion posture information of the vehicle; and based on the motion posture information, controlling a driving component in the trailer hook device to drive the trailer hook component to move relative to the vehicle.

[0032] In this way, the motion posture information can be used to determine the offset between the towed object and the vehicle, and the trailer hook device can be controlled. By driving the activity of the trailer hook assembly, part of the interference of the offset to the vehicle can be offset, thereby reducing the shaking of the vehicle during towing and improving the driving experience.

[0033] In some embodiments, based on motion posture information, controlling a drive component in a trailer hook device to drive the trailer hook component to move relative to a vehicle may include: based on motion posture information, controlling a drive component in the trailer hook device to drive the trailer hook component to move along a crossbeam in the trailer hook device, wherein the crossbeam is suitable for being fixed on the vehicle.

[0034] In this way, the crossbeam can provide a guide for the trailer hook assembly, and the driving assembly drives the trailer hook assembly to move relative to the crossbeam to offset part of the offset between the towed object and the vehicle, thereby reducing the shaking of the vehicle.

[0035] In some embodiments, the method may also include: acquiring rear image information of the vehicle; determining the position of the trailer hitch of the towed object based on the rear image information; and controlling the movement of the vehicle based on the position of the trailer hitch so that the trailer hook of the vehicle is close to the trailer hitch.

[0036] In this way, the position of the trailer hitch can be obtained through the rear image information, so that the vehicle movement can be controlled through the vehicle driving system to make the trailer hook close to the trailer hitch of the towed object.

[0037] In some embodiments, the method may further include: obtaining the relative position relationship between the trailer hitch and the trailer hook; based on the relative position relationship, controlling the driving component in the trailer hook device to drive the trailer hook component to move so as to dock the trailer hitch with the trailer hook.

[0038] Based on the relative position relationship, it can be determined whether the positions of the trailer hitch and the trailer hook have reached the docking position range. After reaching the docking position range, the driving component in the trailer hook device is controlled to drive the trailer hook component to move and adjust the trailer hook position to dock the trailer hitch with the trailer hook.

[0039] In some embodiments, the method may further include: in response to detecting that the towed object is disconnected from the trailer hook assembly, controlling the driving assembly in the trailer hook device to drive the trailer hook assembly to move, so as to store the trailer hook assembly in a storage box of the trailer hook device. In this way, when the towing task is not required, the trailer hook can be stored in the storage box.

[0040] In some embodiments, the method may further include: in response to detecting that an emergency safety event has occurred or is about to occur in the vehicle, controlling the towed object to be disconnected from the vehicle.

[0041] When the vehicle detects that an emergency safety event has occurred or is about to occur, such as rollover, skidding or collision, it can control the disconnection between the towed object and the vehicle, reducing possible damage to the main vehicle and improving the safety and stability of the vehicle.

[0042] In a third aspect, the present application provides an electronic device, which includes a processor and a memory connected to the processor, the memory is used to store computer instructions, and the computer instructions are loaded and executed by the processor to enable the electronic device to implement the method of the second aspect above.

[0043] In a fourth aspect, the present application provides a computer-readable storage medium having computer instructions stored thereon. When the computer instructions are executed on a computer, the computer executes the method of the second aspect.

[0044] In a fifth aspect, the present application provides a vehicle, comprising the trailer hook device of the first aspect, the electronic device of the third aspect, or the computer-readable storage medium of the fourth aspect.

[0045] In a sixth aspect, the present application provides a computer program product, which includes computer instructions. When the computer instructions are executed on a computer, the computer executes the method of the second aspect.

[0046] The beneficial effects of the second to sixth aspects mentioned above refer to the corresponding description of the first aspect and will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0071] As the number of cars increases, the functions of cars are becoming more and more diversified. Vehicles are usually equipped with trailers, which can tow luggage carts to move with the vehicle or tow stranded vehicles to a safe area.

[0072] The trailer device generally includes a trailer hitch arranged in front of the vehicle and a trailer hook arranged at the rear of the vehicle. The trailer hook can be used to connect with the trailer hitch of the towed object so that the vehicle can tow the towed vehicle to move.

[0073] However, since the towed object cannot control its direction autonomously, it will swing irregularly during driving, thus affecting the driving posture and comfort of the main vehicle.

[0074] Based on this, an embodiment of the present application provides a trailer hook device, which is movably connected to the vehicle through a trailer hook assembly, so that the trailer hook assembly moves relative to the vehicle when the towed object swings, thereby reducing the impact of the swing of the towed object on the vehicle.

[0075] The embodiments provided in this application are described in detail below in conjunction with the accompanying drawings.

[0076] Please refer to Figure 1 , Figure 1 A structural schematic diagram of a trailer hook device 100 provided in an embodiment of the present application, the trailer hook device 100 may include a trailer hook assembly 1, the trailer hook assembly 1 may be movably connected to a vehicle, and the trailer hook assembly 1 is used to connect to a towed object so that the towed object can move along with the movement of the vehicle.

[0077] Since the trailer hook assembly 1 is movably connected to the vehicle, when the towed object swings irregularly, the trailer hook assembly 1 can move relative to the vehicle, thereby reducing the shaking of the vehicle itself caused by the swinging of the towed object.

[0078] If the towed object swings with a large amplitude, and the trailer hook assembly 1 moves with the towed object, it will still cause the vehicle to shake, and may cause the life of the trailer hook assembly 1 to be reduced and the loss to be increased. Therefore, the trailer hook device 100 provided in the embodiment of the present application may also include a driving assembly 2, which can drive the trailer hook assembly 1 to move relative to the vehicle.

[0079] In this way, the driving assembly 2 can drive the trailer hook assembly 1 to move relative to the vehicle to offset the impact of the swing of the towed object on the vehicle, thereby reducing the shaking of the vehicle and improving the comfort of the vehicle. In addition, the trailer hook assembly 1 will not swing irregularly with the towed object, and can limit the moving track of the towed object to reduce the swing of the towed object.

[0080] In some embodiments of the present application, the trailer hook assembly 1 can be movably connected to the vehicle along the width direction of the vehicle, and the driving assembly 2 can drive the trailer hook assembly 1 to move along the width direction of the vehicle.

[0081] In this way, during the towing process, the interference of the swing of the towed object on the vehicle along the width direction can be reduced, thereby reducing the shaking of the vehicle and improving the driving experience.

[0082] In some embodiments of the present application, the trailer hook device 100 may further include a crossbeam 3 , which may be fixedly connected to the vehicle and extend along the width direction of the vehicle, and the drive assembly 2 is used to drive the trailer hook assembly 1 to move along the crossbeam 3 .

[0083] In this way, the cross beam 3 can provide a guide for the trailer hook assembly 1, so that the trailer hook assembly 1 can move relative to the cross beam 3 to offset the swing of the towed object, thereby reducing the shaking of the vehicle.

[0084] In a possible structural design, the driving assembly 2 can be connected to the cross beam 3, and the driving assembly 2 can move relative to the cross beam 3 along the width direction of the vehicle to drive the trailer hook assembly 1 to move along the width direction of the vehicle.

[0085] In another possible structural design, the trailer hook assembly 1 can be connected to the cross beam 3, and the driving assembly 2 drives the trailer hook assembly 1 to move on the cross beam 3, so that the trailer hook assembly 1 can move along the width direction of the vehicle.

[0086] In some embodiments, a mounting portion 4 is disposed on the cross beam 3 , and the mounting portion 4 can be used to fix the cross beam 3 on the vehicle so that the trailer hook assembly 1 can move relative to the vehicle.

[0087] In some embodiments, the mounting portion 4 may include a first mounting portion 41 and a second mounting portion 42, and the first mounting portion 41 and the second mounting portion 42 are respectively arranged at opposite ends of the beam 3. In this way, two mounting points can be provided for the beam 3, making the trailer hook device 100 more securely installed.

[0088] In addition, the first mounting portion 41 and the second mounting portion 42 are disposed at both ends of the trailer hook assembly 1, which can prevent the mounting portion 4 from interfering with the movement of the trailer hook assembly 1, thereby making the movement of the trailer hook assembly 1 smoother and reducing vehicle shaking.

[0089] The cross beam 3 is connected to the rear end of the vehicle through the first mounting portion 41 and the second mounting portion 42 . The cross beam 3 can constitute at least a part of the rear anti-collision beam of the vehicle to provide anti-collision protection for the rear of the vehicle.

[0090] In some embodiments of the present application, the trailer hook device 100 may further include a longitudinal beam, the longitudinal beam is fixedly connected to the vehicle and extends in the height direction of the vehicle, and the cross beam 3 is slidably connected to the longitudinal beam, so that the trailer hook assembly 1 slides in the height direction of the vehicle. In this way, it is convenient to connect the trailer hook assembly 1 to the trailer hook on the towed object.

[0091] In some embodiments, the longitudinal beam may include a first longitudinal beam and a second longitudinal beam, the first mounting portion 41 may be slidably connected to the first longitudinal beam, and the second mounting portion 42 may be slidably connected to the second longitudinal beam, so that the cross beam 3 can slide more smoothly along the longitudinal beam.

[0092] In some embodiments of the present application, the trailer hook assembly 1 may include a sliding member 11 and a trailer hook 12 connected to the sliding member 11 , the sliding member 11 may be slidably connected to the crossbeam 3 , and the driving assembly 2 is connected to the sliding member 11 .

[0093] In this way, the driving assembly 2 can drive the sliding member 11 to slide along the cross beam 3 and drive the trailer hook 12 to move along the cross beam 3, thereby offsetting the swing of the towed object and reducing the shaking of the vehicle.

[0094] In a possible structural design, the driving assembly 2 may include a driving member, which is directly connected to the sliding member 11 and slides synchronously with the sliding member 11 .

[0095] In another possible structural design, the driving assembly 2 may include a driving member and a transmission member, wherein the transmission member is connected between the driving member and the sliding member 11, and the driving member is fixedly connected to the cross beam 3. The driving member outputs power to the transmission member, and the sliding member 11 is driven to slide along the cross beam 3 through the transmission of the transmission member. Exemplarily, the transmission member may be a chain.

[0096] In some embodiments of the present application, the trailer hook assembly 1 may further include a switching member 13 , which is connected between the sliding member 11 and the trailer hook 12 , and the switching member 13 allows the trailer hook 12 to switch between an extended state and a retracted state relative to the sliding member 11 .

[0097] When the sliding member 11 is in the unfolded state, the trailer hook 12 can be used to connect with the towed object so as to drag the towed object to move along with the movement of the vehicle; when the towed object does not need to be towed, the switching member 13 can switch the towed object to the stowed state. In this way, the trailer hook 12 can be stowed when not in use, thereby making the vehicle more beautiful and preventing the trailer hook 12 from being exposed and causing increased damage to the vehicle when the vehicle collides.

[0098] In some embodiments of the present application, the trailer hook 12 may include a connecting arm 121 and a trailer portion 122, the two ends of the connecting arm 121 in the extension direction are respectively a first end 1211 and a second end 1212, the first end 1211 can be connected to the switching member 13, and the trailer portion 122 is arranged at the second end 1212; when the trailer hook 12 is in the deployed state, the extension direction of the connecting arm 121 intersects with the cross beam 3, and when the trailer hook 12 is in the retracted state, the extension direction of the connecting arm 121 is parallel to the cross beam 3.

[0099] The trailer part 122 is used to connect the towed object. The connecting arm 121 is connected between the switching member 13 and the trailer part 122, which can increase the distance between the switching member 13 and the trailer part 122, thereby making the connection between the towed object and the trailer part 122 more convenient. In addition, increasing the distance between the cross beam 3 and the trailer part 122 can prevent the towed object from moving forward due to inertia when the vehicle is braking, thereby preventing damage to the vehicle.

[0100] When the trailer hook 12 is in the deployed state, the extension direction of the connecting arm 121 intersects with the cross beam 3, which can increase the distance between the cross beam 3 and the trailer part 122; when the trailer hook 12 is in the stored state, the extension direction of the connecting arm 121 is parallel to the cross beam 3, which can make the appearance of the vehicle more beautiful and prevent the trailer hook 12 from protruding from the cross beam 3, causing increased damage to the vehicle when a vehicle collision occurs.

[0101] In some embodiments, a solenoid valve is provided on the trailer hook 12. When the solenoid valve is energized, the trailer portion 122 can absorb the trailer hook. In this way, when the trailer hook 12 is in the unfolded state and the trailer hook 12 is connected to the towed object, the solenoid valve is energized, and the trailer portion 122 absorbs the trailer hook of the towed object, thereby locking the trailer hook and the trailer hook 12 to prevent the towed object from falling off the trailer hook 12.

[0102] In some embodiments of the present application, the switching member 13 may be a rotating member 13A, and the switching member 13 allows the trailer hook 12 to rotate relative to the sliding member 11 between the deployed state and the stored state.

[0103] In this way, the trailer hook 12 can rotate relative to the sliding member 11, so that the trailer hook 12 can be flexibly switched between the deployed state and the stored state by rotating, and the operation is simple and convenient.

[0104] In some embodiments of the present application, the trailer hook assembly 1 may further include a locking structure, and the locking structure is used to lock the trailer hook 12 to keep the trailer hook 12 in the deployed state.

[0105] In this way, when the trailer hook 12 needs to tow the towed object, the locking structure can lock the trailer hook 12 to keep the trailer hook 12 in the deployed state, preventing the trailer hook 12 from rotating between the deployed state and the stowed state to cause the towed object to swing.

[0106] In a possible structural design, after the vehicle is connected to the towed object, the vehicle starts to move, and the trailer hook assembly 1 is subjected to a dragging force from the towed object. At this time, the locking mechanism works to lock the position of the towing hook to maintain the deployed state.

[0107] In another possible structural design, when the trailer hook 12 needs to tow an object, the trailer hook 12 switches from the stowed state to the deployed state. At this time, the locking mechanism works to lock the position of the towing hook to maintain the deployed state.

[0108] Please refer to Figure 1 , Figure 2 and Figure 3 , Figure 2 This is a schematic diagram of the structure of a storage box 5 provided in an embodiment of the present application. Figure 3 It is a structural schematic diagram of the trailer hook 12 in the storage state. In some embodiments of the present application, the trailer hook device 100 may further include a storage box 5, and the drive assembly 2 may also be used to drive the trailer hook 12 to slide along the cross beam 3 into the storage box 5, and when the trailer hook 12 is located in the storage box 5, the trailer hook 12 is in the storage state.

[0109] In this way, when the vehicle does not need to perform a towing task, the trailer hook 12 is in a stored state. By providing the storage box 5, the trailer hook 12 can be hidden at the bottom of the vehicle, thereby increasing the aesthetics of the vehicle.

[0110] In some embodiments of the present application, the storage box 5 may include a first side wall 51 and a second side wall 52 that are opposite and spaced apart, and a storage space is formed between the first side wall 51 and the second side wall 52. The storage space may be used to store the trailer hook 12.

[0111] Before the trailer hook 12 enters the storage box 5, the trailer hook 12 is in the unfolded position, the direction from the first end 1211 to the second end 1212 is consistent with the direction from the first side wall 51 to the second side wall 52, and along the extension direction of the crossbeam 3, the storage space is opposite to the first end 1211.

[0112] Since the first end 1211 is connected to the sliding member 11 , the storage space is opposite to the first end 1211 along the extension direction of the beam 3 . When the trailer hook 12 is stored, the driving assembly 2 can drive the sliding member 11 to slide along the beam 3 to the storage space.

[0113] When the driving assembly 2 drives the trailer hook 12 to slide along the cross beam 3 toward the storage space, the second side wall 52 presses the connecting arm 121 to rotate the trailer hook 12 from the deployed position to the stored position.

[0114] In this way, when the driving component 2 drives the trailer hook 12 to slide along the cross beam 3 toward the storage space, the driving component 2 drives the sliding member 11 to slide into the storage space. Since the trailer hook 12 is in the deployed state, the trailer hook 12 cannot directly enter the storage space. The second side wall 52 applies an extrusion force to the connecting arm 121, which can rotate the rotating member 13A, thereby rotating the trailer hook 12 from the deployed position to the storage position.

[0115] In some embodiments of the present application, before the trailer hook 12 enters the storage box 5, the end of the first side wall 51 facing the trailer hook 12 is the third end 503, and the end of the second side wall 52 facing the trailer hook 12 is the fourth end 504; a first guide surface 501 is provided between the inner wall surface of the first side wall 51 and the end surface of the third end 503, and a second guide surface 502 is provided between the inner wall surface of the second side wall 52 and the end surface of the fourth end 504.

[0116] In this way, when the trailer hook 12 enters the storage space, the first guide surface 501 and the second guide surface 502 can guide the trailer hook 12, so that the trailer hook 12 can enter the storage space more smoothly, avoiding the angle between the inner wall surface of the second side wall 52 and the end surface of the fourth end 504 from blocking and damaging the trailer hook 12.

[0117] Exemplarily, the first guide surface 501 and the second guide surface 502 may be inclined guide surfaces, or the first guide surface 501 and the second guide surface 502 may also be arcuate surfaces.

[0118] In some embodiments of the present application, the storage box 5 also includes a bottom wall 53 connected between the first side wall 51 and the second side wall 52; before the trailer hook 12 enters the storage box 5, the end of the bottom wall 53 facing the trailer hook 12 is the fifth end 505, and the end of the bottom wall 53 away from the trailer hook 12 is the sixth end 506; from the fifth end 505 to the sixth end 506, the inner wall surface of the bottom wall 53 gradually extends upward.

[0119] When the trailer hook 12 enters the storage box 5, as the inner wall surface of the bottom wall 53 gradually extends upward, the trailer hook 12 is gradually lifted upward. In this way, the gap between the trailer hook 12 and the ground can be increased, thereby preventing the trailer hook 12 from hooking foreign objects during driving and causing interference with the driving process.

[0120] In some embodiments, the trailer hook assembly 1 may further include an elastic member, which may be connected between the sliding member 11 and the trailer hook 12. Thus, when the trailer hook 12 is gradually lifted upward, the elastic member is compressed, so that the trailer hook 12 can be lifted.

[0121] The embodiment of the present application also provides a vehicle, which may include the above-mentioned trailer hook device 100 to realize the function of towing the towed object. When the vehicle is towing, since the driving component 2 can drive the trailer hook 12 to move relative to the vehicle, the vehicle shakes less during the towing process, thereby improving the driving comfort of the vehicle.

[0122] The embodiment of the present application also provides a control method of a trailer hook device 100 , which can be used to control the trailer hook device 100 provided by the embodiment of the present application.

In some embodiments, the vehicle may include a motion posture acquisition device, which can be used to collect motion posture information.

[0126] Exemplarily, the motion posture information may include the vehicle's driving trajectory offset, the vehicle's roll angle and the vehicle's tail swing angle. The motion posture acquisition device may include a camera, a distance sensor or an angle sensor, and the above-mentioned motion posture information is obtained through detection by the camera, the distance sensor or the angle sensor.

[0127] S102 . Based on the motion posture information, control the driving component 2 in the trailer hook device 100 to drive the trailer hook component 1 to move relative to the vehicle.

[0128] In some embodiments, the vehicle may further include a controller, and the motion posture acquisition device transmits the collected motion posture information to the controller. In this way, the offset between the towed object and the vehicle can be determined through the motion posture information. The controller can control the trailer hook device 100, and by driving the activity of the trailer hook assembly 1, part of the interference of the offset to the vehicle can be offset, thereby reducing the shaking of the vehicle during towing and improving the driving experience.

[0129] Please refer to Figure 6 , Figure 6 The second schematic diagram of a control method of a trailer hook device 100 provided in an embodiment of the present application, in some embodiments, the trailer hook device 100 may include a crossbeam 3 fixedly connected to the vehicle, and the step S102 may include:

[0130] S1021 . Based on the motion posture information, control the driving assembly 2 in the trailer hook device 100 to drive the trailer hook assembly 1 to move along the crossbeam 3 in the trailer hook device 100 .

[0131] In this way, the cross beam 3 can provide a guide for the trailer hook assembly 1, and the driving assembly 2 drives the trailer hook assembly 1 to move relative to the cross beam 3 to offset part of the offset between the towed object and the vehicle, thereby reducing the shaking of the vehicle.

[0132] Please refer to Figure 7 , Figure 7 The third schematic diagram of a control method of a trailer hook device 100 provided in an embodiment of the present application. In some embodiments of the present application, the control method of the trailer hook device 100 may further include the following steps:

[0135] Exemplarily, the rear-end image acquisition and analysis device may include a camera and a processor, wherein the camera is used to acquire an image of the towed object, and the processor is used to analyze the image.

[0136] S202, determining the position of the trailer hook of the towed object based on the rear image information;

[0137] The processor analyzes the relative position of the towed object and the vehicle through the acquired rear image information, and determines the position of the trailer hitch through the position of the trailer hitch on the towed object and the above relative position.

[0138] S203: Based on the position of the trailer hitch, control the vehicle to move so that the trailer hook 12 is close to the trailer hitch of the towed object.

[0139] In some embodiments, the vehicle includes a vehicle driving system. In one possible implementation, the vehicle driving system can control the vehicle to perform driving operations. Exemplarily, the driving operations can include moving forward, moving backward, turning, and braking.

[0140] In another possible implementation, the vehicle driving system may include a display screen, and the controller may display the driving information on the display screen, and the driver may adjust the vehicle position according to the driving information.

[0141] In this way, the rear image acquisition and analysis device can transmit the position of the trailer hitch to the controller, and the controller can process the vehicle driving information and then control the vehicle movement through the vehicle driving system to make the trailer hook 12 close to the trailer hitch of the towed object.

[0142] In some embodiments of the present application, the control method of the trailer hook device 100 may further include the following steps:

[0143] S204, obtaining the relative position relationship between the trailer hitch and the trailer hook 12;

[0144] The vehicle driving system controls the movement of the vehicle so that the trailer hook 12 is close to the trailer hitch of the towed object. During the movement, the rear image acquisition and analysis device continuously acquires images of the towed object to obtain the position of the trailer hitch. After the controller receives the position of the trailer hitch, it analyzes and obtains the relative position relationship between the trailer hitch and the trailer hook 12.

[0145] S205 , based on the relative position relationship, controlling the driving assembly 2 in the trailer hook device 100 to drive the trailer hook assembly 1 to move, so as to dock the trailer hook with the trailer hook 12 .

[0146] According to the relative position relationship, the controller can determine whether the positions of the trailer hitch and the trailer hook 12 have reached a docking position range.

[0147] If the docking position range is reached, the controller controls the driving component 2 in the trailer hook device 100 to drive the trailer hook component 1 to move, adjust the position of the trailer hook 12, and dock the trailer hook with the trailer hook 12.

[0148] If the docking position range is not reached, the controller continues to control the vehicle driving system to adjust the vehicle position so that the positions of the trailer hook and the trailer hook 12 reach the docking position range.

[0149] Please refer to Figure 8 , Figure 8 The fourth schematic diagram of a control method of a trailer hook device 100 provided in an embodiment of the present application.
