[0089] In some embodiments of the present application, the slider 41 is slidably connected to the second vehicle 1 .

[0090] The slider 41 can be slidably mounted on the vehicle frame, that is, mounted on the side of the vehicle, or can be slidably mounted on the vehicle chassis, without limitation.

[0091] Furthermore, the slide 41 is connected to the axle.

[0092] In some embodiments of the present application, the axle adjustment device 100 also includes a main body 3, which is installed on the body of the vehicle, and the adjustment part 4 is connected to the main body 3 and can move relative to the main body 3; that is, in this embodiment, the adjustment part 4 is assembled on the body of the vehicle through the main body 3 to realize the movement of the adjustment part 4 relative to the body of the vehicle 1, thereby being able to adjust the position of the axle on the vehicle.

[0093] In some embodiments of the present application, the main body 3 is installed on the body of the second vehicle 1 , and the adjustment portion 4 is connected to the main body 3 and can move relative to the main body 3 to adjust the position of the first axle 11 on the second vehicle 1 .

[0094] The main body 3 may be mounted on the frame of the vehicle 1 , that is, assembled to the side of the vehicle; or it may be mounted on the chassis of the vehicle 1 ; there is no limitation here.

[0095] In some embodiments of the present application, the main body 3 includes a slide rail 31, the adjustment portion 4 includes a slider 41, the slide rail 31 extends in a first direction of the vehicle, and the slider 41 is slidingly connected to the slide rail 31; in this embodiment, by providing a slider 41 to slide on the slide rail 31, the movable path of the slider 41 is limited, so that the slider 41 can only move along the extension direction of the slide rail 31, and the slider 41 is connected to the axle, thereby ensuring the stability of the axle adjustment device 100 when adjusting the axle of the vehicle.

[0096] It should be noted that the first direction is the front-rear direction of the vehicle, that is, the slider 41 can move in the front-rear direction of the vehicle, so that the axle of the vehicle can move relative to the vehicle in the front-rear direction.

[0097] In some embodiments of the present application, the main body 3 also includes a fixing portion 32, which is fixed to the body of the vehicle 1, and the slide rail 31 is installed on the fixing portion 32; that is, in this embodiment, the fixing portion 32 is provided so that the slide rail 31 is firmly fixed to the body of the vehicle 1.

[0098] In order to prevent the fixing portion 32 from interfering with the sliding movement of the slider 41 on the slide rail 31 , the fixing portion is located at one end of the slide rail 31 and connected to the slide rail 31 .

[0099] In some embodiments of the present application, two fixing portions 32 are provided, and the two fixing portions 32 are respectively located at two ends of the slide rail 31 and connected to the slide rail 31 .

[0100] In some embodiments of the present application, the fixing portion 32 may be mounted on the vehicle frame, that is, assembled to the side of the vehicle, or may be mounted on the chassis of the vehicle, without limitation.

[0101] In some embodiments of the present application, the axle adjustment device 100 also includes a driving member 5, which is connected to the adjustment portion 4 and is configured to drive the adjustment portion 4 to move relative to the body of the vehicle to adjust the position of the axle; that is, in this embodiment, the adjustment portion 4 is driven to move by the driving member 5 to adjust the position of the vehicle's axle, thereby ensuring the balance of the vehicle.

[0102] In some embodiments of the present application, the driving member 5 includes a driving motor 51 and a transmission screw 52, and the transmission screw 52 is connected to the output shaft of the driving motor 51; wherein the adjustment part 4 is screwed on the transmission screw 52 and is locked in rotation with the transmission screw 52; that is, in this embodiment, since the adjustment part 4 is locked in rotation with the transmission screw 52, when the driving motor 51 drives the transmission screw 52 to rotate, the adjustment part 4 will not rotate, and thus, on the basis of threaded cooperation with the transmission screw 52, it can move along the extension direction of the transmission screw 52 to adjust the axle position of the vehicle, thereby ensuring the balance of the vehicle.

[0103] In some embodiments of the present application, the transmission screw 52 extends along the first direction.

[0104] In some embodiments of the present application, the transmission screw 52 is further provided with two fixing portions 32 to support both ends of the transmission screw 52 , thereby improving the stability of the adjustment portion 4 moving on the transmission screw 52 .

[0105] In some embodiments of the present application, the driving motor 51 is installed on the fixing portion 32 .

[0106] The present application also proposes a vehicle, including a first axle 11 and an axle adjustment device 100. The axle adjustment device 100 is connected to the first axle 11 and is used to adjust the position of the first axle. The axle adjustment device 100 is as described above. Since the present vehicle adopts all the technical solutions of all the above embodiments, it at least has the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.

[0107] In some embodiments of the present application, the vehicle also includes a second axle, which is suitable for being fixedly mounted on the vehicle, and the axle adjustment device 100 is used to adjust the position of the first axle 11 relative to the second axle; that is, in this embodiment, the axle adjustment device 100 can adjust the distance between the first axle 11 and the second axle to ensure the balance of the vehicle under different real-time conditions.

[0108] It can be understood that, in this embodiment, the distance between the first axle 11 and the second axle can be adjusted when the vehicle is in a driving state, a stationary state, or a towed and moving state.

[0109] In addition, in some embodiments of the present application, the second axle can be installed on the vehicle body through another axle adjustment device 100, that is, the first axle and the second axle can both move relative to the vehicle body, and the movements of the first axle and the second axle are not synchronized and do not interfere with each other.

[0110] In some embodiments of the present application, the vehicle also includes a second axle, and the axle adjustment device 100 is also connected to the second axle and is used to adjust the position of the second axle; that is, in this embodiment, the axle adjustment device 100 can simultaneously adjust the positions of the first axle 11 and the second axle on the vehicle to ensure the balance of the vehicle under different real-time conditions.

[0111] It can be understood that, in this embodiment, the position adjustment of the first axle 11 and the second axle can be performed when the vehicle is in a driving state, a stationary state, or a towed and moving state.

[0112] In some embodiments of the present application, the first axle and the second axle are arranged in a first direction.

[0113] In some embodiments of the present application, there are two axle adjustment devices 100, and the two axle adjustment devices 100 are spaced apart in the second direction and are both connected to the first axle 11, and the second direction is different from the direction of movement of the first axle 11; wherein, the two adjustment parts 4 in the two axle adjustment devices 100 are both configured to be connected to the first axle 11 of the vehicle; wherein, by providing two axle adjustment devices 100 to adjust the first axle 11 of the vehicle at the same time, the stability of the position adjustment of the first axle 11 of the vehicle is improved.

[0114] In some embodiments of the present application, the moving direction of the first axle 11 is a first direction, that is, a front-rear direction of the vehicle; the second direction is a left-right direction of the vehicle.

[0115] The present application also proposes a vehicle system, including a first vehicle 2 and a second vehicle 1, wherein the second vehicle is used to be towed and moved by the first vehicle 2, and the second vehicle 1 is the vehicle in the above embodiment, or the second vehicle includes the axle adjustment device 100 in the above embodiment; since the present vehicle system adopts all the technical solutions of all the above embodiments, it has at least the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.

[0116] In the vehicle system proposed in the embodiment of the present application, when the second vehicle 1 is being towed and in a driving state, when the second vehicle 1 is turning or subjected to a lateral external force, the axle position on the second vehicle 1 can be adjusted according to the implementation situation to reduce the possibility of lateral imbalance and rollover of the second vehicle 1 when it is being towed and moving.

[0117] In addition, when the second vehicle 1 is being towed and in motion, when the second vehicle 1 is in an uphill or downhill situation, the center of mass position of the second vehicle 1 changes due to the influence of the slope, which will cause the pressure applied by the second vehicle 1 to the first vehicle 2 to change, that is, it will cause interference with the front wheels or rear wheels of the first vehicle 2, thereby affecting the driver's safe driving. At this time, the axle position of the second vehicle 1 can be adjusted according to the real-time situation to ensure the driver's driving safety during driving.

[0118] The present application also proposes an axle adjustment method, comprising:

[0119] Step S10: In response to the vehicle being in an unbalanced state, adjusting the axle positions of the vehicle to keep the vehicle balanced.

[0120] In this embodiment, when it is determined that the vehicle is in an unbalanced state, the position of the axle on the vehicle is adjusted to keep the vehicle balanced, thereby preventing the vehicle from tilting or rolling over.

[0121] It should be explained that the unbalanced state of the vehicle includes the state before the vehicle tends to be unbalanced and the state where the vehicle has already been unbalanced; for example, in one embodiment, the unbalanced state includes the state before the vehicle tends to tilt or swing laterally and the state where the vehicle has already tilted or swung laterally.

[0122] The axle position adjustment of the vehicle can be performed when the vehicle is in a moving state or when the vehicle is in a stationary state.

[0123] For example, in one embodiment, when loading items into a vehicle while the vehicle is stationary, the position of the vehicle's axles is adjusted to keep the vehicle balanced, thereby preventing the vehicle from tilting and causing the items carried in the vehicle to move in a second vehicle.

[0124] For example, in another embodiment, when the vehicle is in motion, the position of one axle on the vehicle is adjusted relative to another axle, so that the vehicle can maintain balance when turning, going uphill or downhill, etc., thereby reducing the possibility of the vehicle losing control or rolling over.

[0125] In some embodiments of the present application, the method further comprises:

[0126] Step S09: determining whether the vehicle is in an unbalanced state according to the vehicle imbalance information.

[0127] In this embodiment, the control logic of the vehicle is as follows: based on the acquired imbalance information of the vehicle, it is determined that the vehicle is in an unbalanced state, and the position of the axle of the vehicle is adjusted according to the imbalance state to keep the vehicle balanced.

[0128] In some embodiments of the present application, the imbalance information includes the positions of axles of the vehicle and the center of mass of the vehicle.

[0129] Step S09 includes:

[0130] Step S091: Determine that the vehicle is in an unbalanced state based on the deviation of the axle position of the vehicle from the center of mass of the vehicle.

[0131] That is, in this embodiment, when the axle position of the vehicle deviates from the center of mass of the vehicle, the vehicle may easily lose its balance while in motion or at rest, and may tilt or roll over.

[0132] In some embodiments of the present application, step S10 includes:

[0133] Step S101: Control the axle of the vehicle to move in a direction close to the center of mass of the vehicle until the vehicle maintains balance.

[0134] In this embodiment, if it is detected that the axle of the vehicle deviates from the center of mass of the vehicle, the position of the axle of the vehicle is adjusted so that the axle of the vehicle is close to the center of mass of the vehicle until the vehicle remains balanced.

[0135] In one embodiment, when a vehicle is driving and turning or receiving lateral external force, due to the position deviation between the center of mass and the axle, the axle position of the vehicle can be adjusted according to the real-time situation to reduce the possibility of lateral imbalance and rollover of the vehicle during driving.

[0136] In another embodiment, when a vehicle is driving and is on an uphill or downhill slope, the center of mass position of the vehicle changes due to the influence of the slope, causing the front wheels or rear wheels of the vehicle connected to the axle to be under excessive pressure, thereby affecting the driver's safe driving. The axle adjustment method in the embodiment of the present application can adjust the axle position of the vehicle according to the real-time situation to ensure the driver's driving safety during driving.

[0137] In another embodiment, when the vehicle is at rest, the axle positions of the vehicle can be adjusted so that the axles are close to the center of mass of the vehicle, so that the vehicle remains balanced. That is, when the vehicle is at rest, the vehicle is prevented from tilting and causing items carried in the vehicle to move within the vehicle.

[0138] In addition, the axle adjustment method further includes controlling the axle adjustment device 100 to fix the position of the axle of the vehicle when the axle of the vehicle does not deviate from the center of mass of the vehicle.

[0139] See also Figure 4 , the present application also proposes an axle adjustment method, comprising:

[0140] Step S100 : In response to the second vehicle 1 being in an unbalanced state, adjusting the axle positions of the second vehicle 1 to keep the second vehicle 1 balanced.

[0141] The second vehicle 1 is adapted to be towed and moved by the first vehicle 2 .

[0142] like Figure 3 As shown, the second vehicle 1 can be connected to the first vehicle 2 to be towed by the first vehicle 2. During this towing activity, if the second vehicle 1 is in an unbalanced state, the position of the first axle 11 of the second vehicle 1 is adjusted to keep the second vehicle 1 balanced.

[0143] It should be explained that the unbalanced state includes the state before the second vehicle 1 shows an unbalanced tendency and the state in which the unbalance has occurred; for example, in one embodiment, the unbalanced state includes the state before the second vehicle 1 shows a tendency to tilt or swing laterally and the state in which the second vehicle 1 has already tilted or swung laterally.

[0144] Furthermore, the position adjustment of the first axle 11 of the second vehicle 1 may be performed when the second vehicle 1 is moving, or may be performed when the second vehicle 1 is stationary.

[0145] In one embodiment, when the second vehicle 1 is towed by the first vehicle 2 and is in a moving state, the second vehicle 1 is kept balanced by adjusting the position of the first axle 11 of the second vehicle 1; if the second vehicle 1 is turning or subjected to a lateral external force, the position of the first axle 11 of the second vehicle 1 can be adjusted according to the real-time situation to reduce the possibility of lateral imbalance and rollover of the second vehicle 1 when it is towed and in a moving state.

[0146] In addition, when the second vehicle 1 is not towed and is stationary, the position of the first axle 11 of the second vehicle 1 can also be adjusted. For example, when the second vehicle 1 is stationary and items are being loaded into the second vehicle 1, the position of the first axle 11 of the second vehicle 1 can be adjusted to keep the second vehicle 1 balanced, thereby preventing the second vehicle 1 from tilting and causing the items carried in the second vehicle 1 to move within the second vehicle 1.

[0147] In some embodiments of the present application, the axle adjustment method further includes:

[0148] Step S90: determining that the second vehicle 1 is in an unbalanced state according to the unbalance information of the second vehicle 1 .

[0149] In this embodiment, the control logic of the second vehicle 1 is as follows: based on the acquired imbalance information of the second vehicle 1, it is determined that the second vehicle 1 is in an unbalanced state, and the position of the first axle 11 of the second vehicle 1 is adjusted according to the imbalance state to keep the second vehicle 1 balanced.

[0150] In some embodiments of the present application, the imbalance information includes the tongue weight of the second vehicle 1 and the dead weight of the second vehicle 1; wherein, the tongue weight of the second vehicle 1 is the ballast weight applied by the second vehicle 1 to the first vehicle 2 when the second vehicle 1 is connected to the first vehicle 2, and the dead weight of the second vehicle 1 includes the weight of the second vehicle and the weight of the items or people it carries.

[0151] In some embodiments of the present application, step S90 includes:

[0152] Step S901: Based on the ratio of the tongue weight of the second vehicle 1 to the dead weight of the second vehicle 1 not satisfying a preset range, it is determined that the second vehicle 1 is in an unbalanced state.

[0153] That is, in this embodiment, when the ratio of the tongue weight of the second vehicle 1 to the own weight of the second vehicle 1 does not meet the preset range, the second vehicle 1 may easily lose its balance when being towed and moving or when stationary, and may tilt, roll over, etc.

[0154] The ratio of the tongue weight of the second vehicle 1 to the deadweight of the second vehicle 1 is obtained and compared with a preset interval to confirm that the ratio of the tongue weight of the second vehicle 1 to the deadweight of the second vehicle 1 does not meet the preset interval. At this time, the second vehicle 1 is in an unbalanced state.

[0155] Among them, a tongue weight detection device 7 is provided at the connection position between the first vehicle 2 and the second vehicle 1, so as to obtain the tongue weight information of the second vehicle 1 in real time when the first vehicle 2 is connected to the second vehicle 1 and does not move, and when the first vehicle 2 is pulling the second vehicle 1 to move, so as to calculate the ratio of the tongue weight of the second vehicle 1 to the dead weight of the second vehicle 1.

[0156] In one embodiment, when the second vehicle 1 is moving and turning or receiving a lateral external force, the position of the first axle 11 of the second vehicle 1 can be adjusted according to the real-time situation to reduce the possibility of lateral imbalance and rollover of the second vehicle 1 while being towed and moving.

[0157] In another embodiment, when the second vehicle 1 is driving and is on an uphill or downhill slope, the center of mass position of the second vehicle 1 changes due to the influence of the slope, which will cause the tongue weight of the second vehicle 1 to change, that is, it will cause interference with the front wheels or rear wheels of the first vehicle 2, thereby affecting the driver's safe driving. At this time, the position of the first axle 11 of the second vehicle 1 can be adjusted according to the real-time situation to ensure the driver's driving safety during driving.

[0158] In addition, the axle adjustment method further includes controlling the axle adjustment device 100 to fix the position of the first axle 11 of the second vehicle 1 when the ratio of the tongue weight of the second vehicle 1 to the dead weight of the second vehicle 1 satisfies a preset range.

[0159] In some embodiments of the present application, step S100 includes:

[0160] Step S1001: Determine whether the ratio of the tongue weight of the second vehicle 1 to the weight of the second vehicle 1 is greater than a preset range.

[0161] Step S1002: Control the axle of the second vehicle 1 to move toward the first vehicle 2 until the second vehicle 1 maintains balance.

[0162] Among them, when the ratio of the tongue weight of the second vehicle 1 to the dead weight of the second vehicle 1 is greater than a preset range, the pressure applied by the second vehicle 1 to the first vehicle 2 is too great, and the first axle 11 of the second vehicle 1 is controlled to move toward the first vehicle 2 until the second vehicle 1 maintains balance; this can reduce the possibility of the second vehicle 1 tilting, swaying laterally, or even rolling over during the towing process.

[0163] In some embodiments of the present application, step S100 includes:

[0164] Step S1003: determining that the ratio of the tongue weight of the second vehicle 1 to the dead weight of the second vehicle 1 is less than a preset range;

[0165] Step S1004: Control the axle of the second vehicle 1 to move in a direction away from the first vehicle 2 until the second vehicle 1 maintains balance.

[0166] Among them, when the ratio of the tongue weight of the second vehicle 1 to the dead weight of the second vehicle 1 is less than a preset range, the pressure applied by the second vehicle 1 to the first vehicle 2 is too small, and the first axle 11 of the second vehicle 1 is controlled to move away from the second vehicle 1 until the first vehicle 2 is balanced; this can reduce the possibility of tilting, lateral swinging or even rollover of the second vehicle 1 during the towing process.

[0167] It should be supplemented that the first vehicle 2 pulls the second vehicle 1 in the first direction, that is, the first axle 11 of the first vehicle 2 can move relative to the first vehicle 2 in the first direction.

[0168] In some embodiments of the present application, the first direction is the front-to-back direction of the second vehicle 1, and the first vehicle 2 can be located on any side of the second vehicle 1 in the front-to-back direction, and the first axle 11 of the first vehicle 2 can move relative to the first vehicle 2 in the front-to-back direction.

[0169] In some embodiments of the present application, the preset interval is 10% to 15%; that is, if the ratio of the tongue weight of the second vehicle 1 to the dead weight of the second vehicle 1 does not meet 10% to 15%, the second vehicle 1 is prone to tilting, swaying laterally or even overturning during the towing process.

[0170] In some embodiments of the present application, the imbalance information includes the position of the first axle 11 of the second vehicle 1 and the center of mass of the second vehicle 1 .

[0171] Step S90 includes:

[0172] Step S902 : Based on the deviation of the axle position of the second vehicle 1 from the center of mass of the second vehicle 1 , it is determined that the second vehicle 1 is in an unbalanced state.

[0173] Among them, if the position of the first axle 11 of the second vehicle 1 deviates from the center of mass of the second vehicle 1, the second vehicle 1 is likely to tilt, and when the second vehicle 1 is connected to the first vehicle 2, a greater pressure will be applied to the first vehicle 2. For example, in one embodiment, the first axle 11 of the second vehicle 1 is located between the center of mass of the second vehicle 1 and the first vehicle 2, which will make the rear wheels of the first vehicle 2 prone to slipping, and even lift the rear wheels of the first vehicle 2 off the ground; in another embodiment, if the center of mass of the second vehicle 1 is located between the first axles 11 of the first vehicle 2 and the second vehicle 1, the front wheels of the first vehicle 2 are likely to slip, thereby reducing the turning ability of the first vehicle 2, and even lift the front wheels of the first vehicle 2 off the ground.

[0174] In this embodiment, by obtaining the position of the first axle 11 of the second vehicle 1, the position of the first axle 11 of the second vehicle 1 is compared with the center of mass position of the second vehicle 1 to determine that the position of the first axle 11 of the second vehicle 1 deviates from the center of mass of the second vehicle, and to determine that the second vehicle 1 is in an unbalanced state.

[0175] In some embodiments of the present application, step S100 includes:

[0176] Step S1005: Control the axle of the second vehicle 1 to move in a direction close to the center of mass of the second vehicle 1 until the second vehicle 1 maintains balance.

[0177] In this embodiment, if it is detected that the first axle 11 of the second vehicle 1 deviates from the center of mass of the second vehicle 1 , the axle position of the second vehicle 1 is adjusted so that the axle of the second vehicle 1 is close to the center of mass of the second vehicle 1 until the second vehicle 1 remains balanced.

[0178] In one embodiment, when the second vehicle 1 is being towed and moving and is turning or receiving a lateral external force, the axle position of the second vehicle 1 can be adjusted according to the real-time situation to reduce the possibility of lateral imbalance and rollover of the second vehicle 1 while being towed and moving.

[0179] In another embodiment, the second vehicle 1 is being towed and is in an uphill or downhill situation. At this time, due to the influence of the slope, the center of mass position of the second vehicle 1 changes, which will cause the tongue weight value of the second vehicle 1 to change, that is, it will cause interference with the front wheels or rear wheels of the first vehicle 2, thereby affecting the driver's safe driving. The axle adjustment method in the embodiment of the present application can adjust the position of the first axle 11 of the second vehicle 1 according to the real-time situation to ensure the driver's driving safety during driving.

[0180] In another embodiment, when the second vehicle 1 is untowed and stationary, the position of the first axle 11 of the second vehicle 1 can be adjusted so that the first axle 11 of the second vehicle 1 is close to the center of mass of the second vehicle 1, so that the second vehicle 1 remains balanced. That is, when the second vehicle 1 is untowed and stationary, the balance of the second vehicle 1 can be achieved only by the wheels of the second vehicle 1 being in contact with the ground, thereby preventing the second vehicle 1 from tilting and causing the items carried in the second vehicle 1 to move within the second vehicle 1.

[0181] In addition, the axle adjustment method further includes controlling the axle adjustment device 100 to fix the position of the first axle 11 of the second vehicle 1 when the first axle 11 of the second vehicle 1 does not deviate from the center of mass of the second vehicle 1 .
