[0035] To make the technical problems solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0036] The present invention provides a vehicle including a lateral movement device as described below. This lateral movement device is applied to the vehicle to enable lateral movement of the vehicle.

[0037] like Figure 1 As shown, the lateral movement device provided in the embodiment of the present invention includes a liquid supply device 10 and a plurality of lateral movement mechanisms 20. The plurality of lateral movement mechanisms 20 are arranged in a one-to-one correspondence with a plurality of wheels 100, and all of the plurality of lateral movement mechanisms 20 are connected to the liquid supply device 10. The lateral movement mechanism 20 includes a shock absorber 201 and a hydraulic cylinder 202. The hydraulic cylinder 202 and the shock absorber 201 are selectively connected to the liquid supply device 10 so that the liquid supply device 10 can supply liquid to the hydraulic cylinder 202 or the shock absorber 201. The top end of the shock absorber 201 is adapted to be connected to the vehicle body, and the bottom end of the shock absorber 201 is adapted to be connected to the wheel 100, so that when the fluid supply device 10 supplies fluid to the shock absorber 201, the shock absorber 201 can raise the vehicle body at the corresponding wheel 100; the outer end of the hydraulic cylinder 202 is adapted to be connected to the wheel 100, and the inner end of the hydraulic cylinder 202 is adapted to be connected to the vehicle body, so that when the fluid supply device 10 supplies fluid to the hydraulic cylinder 202, the hydraulic cylinder 202 can drive the corresponding wheel 100 to move along the width direction of the vehicle.

[0038] The lateral movement device provided by this invention, by incorporating a shock absorber 201 and a hydraulic cylinder 202, can simultaneously raise the vehicle and move the wheels 100 in the width direction of the vehicle. The lateral movement of the vehicle can be decomposed into the lateral movement of each wheel, meaning it can be achieved through the lateral movement of each wheel. Thus, when parallel parking, simply park the vehicle parallel to the parking space and then use the lateral movement device to complete the parallel parking, significantly reducing the difficulty of parallel parking. Compared to traditional vehicles, vehicles equipped with a lateral movement device can directly achieve lateral movement without repeatedly reversing or adjusting the direction, making operation simple and convenient. Furthermore, the lateral movement mechanism 20 of the lateral movement device provided by this invention can both raise the vehicle's height and achieve lateral movement, with both functions sharing the hydraulic supply device 10, simplifying the structure.

[0039] The working principle of the lateral movement device provided by the present invention is as follows: the lateral movement of the vehicle can be decomposed into the lateral movement of each wheel. The four wheels move laterally in sequence. When a specific wheel moves laterally, the shock absorbers of the other wheels raise the vehicle body so that the wheel that needs to move laterally is suspended in the air. At this time, most of the weight of the vehicle is borne by the other three wheels, which greatly reduces the resistance of the wheel's lateral movement and avoids excessive wear of the wheel during lateral movement.

[0040] The lateral movement mechanism 20 of this invention has four parts, corresponding to the left front wheel, right front wheel, left rear wheel, and right rear wheel, respectively. When the left front wheel moves laterally, the shock absorbers corresponding to the right front wheel, left rear wheel, and right rear wheel raise the vehicle body, thereby suspending the left front wheel in the air. There is no specific restriction on the order in which the wheels move laterally. For example, when the vehicle needs to move to the left, the left front wheel, right front wheel, left rear wheel, and right rear wheel can move to the left in sequence, or the left front wheel, left rear wheel, right front wheel, and right rear wheel can move to the left in sequence.

[0041] The vehicle body of the present invention includes at least a body and a frame, for example, the top end of the shock absorber 201 is connected to the body, and the inner end of the hydraulic cylinder 202 is connected to the frame.

[0042] Both the shock absorber 201 and the hydraulic cylinder 202 can be connected to the wheel 100 via the swing arm 200. More specifically, both the shock absorber 201 and the hydraulic cylinder 202 are adapted to be connected to the swing arm 200, which is adapted to connect to the wheel 100.

[0043] In one embodiment of the present invention, such as Figure 1As shown, the lateral movement mechanism 20 also includes a first control valve 203. One end of the first control valve 203 is connected to the liquid supply device 10 via a first connecting pipe 204, and the other end of the first control valve 203 is connected to the shock absorber 201. The hydraulic cylinder 202 is connected to the first connecting pipe 204. At this time, at least a portion of the structure of the first connecting pipe 204 leading to the liquid supply device 10 is a shared part for both the height lifting function and the lateral movement function, thus simplifying the overall structure. This invention integrates a lateral movement function based on an active suspension (capable of raising vehicle height). By setting the first control valve 203, when a wheel needs to move laterally, the body lifting function of the corresponding wheel can be locked. This allows the corresponding wheel to be suspended in the air, and also allows the liquid in the liquid supply device 10 to only enter the hydraulic cylinder 202, thereby achieving rapid lateral movement of the corresponding wheel.

[0044] like Figure 1 and Figure 2 As shown, the hydraulic cylinder 202 includes a cylinder body 2021, a first piston 2022, and a first piston rod 2023. The first piston 2022 is disposed inside the cylinder body 2021 to divide the cylinder body 2021 into a first chamber 2024 and a second chamber 2025. One end of the first piston rod 2023 is connected to the first piston 2022, and the other end of the first piston rod 2023 is adapted to be connected to the wheel 100. The first piston rod 2023 extends along the width direction of the vehicle. The inlet of the first chamber 2024 and the inlet of the second chamber 2025 are selectively connected to the first connecting pipe 204. The outlet of the first chamber 2024 and the outlet of the second chamber 2025 are selectively connected to the liquid supply device 10. When one of the first chamber 2024 and the second chamber 2025 is connected to the first connecting pipe 204, the other of the first chamber 2024 and the second chamber 2025 is connected to the liquid supply device 10. In other words, the connection channel between the cylinder 2021 and the liquid supply device 10 can only be connected through one path, thereby enabling the vehicle to move in one direction.

[0045] The first piston rod 2023 of the present invention extends along the width direction of the vehicle, so that when the pressure in the first chamber 2024 or the second chamber 2025 changes and causes the first piston rod 2023 to move, the corresponding wheel can move along the width direction of the vehicle. It is understood that the extension of the first piston rod 2023 along the width direction of the vehicle can be interpreted as the first piston rod 2023 extending approximately along the width direction of the vehicle; it is not strictly required that the angle between the first piston rod 2023 and the horizontal line be zero, as long as the angle between the first piston rod 2023 and the horizontal line is within a small preset range.

[0046] In such Figure 1 and Figure 2In the illustrated embodiment, the distance from the first chamber 2024 to the centerline of the vehicle's width direction is greater than the distance from the second chamber 2025 to the centerline of the vehicle's width direction. That is, the first chamber 2024 is located on the outer side closer to the wheel, and the second chamber 2025 is located on the inner side farther from the wheel. When the inlet of the first chamber 2024 is connected to the first connecting pipe 204, and the outlet of the second chamber 2025 is connected to the liquid supply device 10, the wheel moves towards the other wheel on the same axle. For example, the left front wheel moves towards the right front wheel, i.e., to the right. Similarly, the right front wheel moves towards the left front wheel, i.e., to the left. When the inlet of the second chamber 2025 is connected to the first connecting pipe 204, and the outlet of the first chamber 2024 is connected to the liquid supply device 10, the wheel moves away from the other wheel on the same axle. For example, the left front wheel moves away from the right front wheel, i.e., to the left. Taking the right front wheel as an example, the right front wheel moves away from the left front wheel, that is, it moves to the right.

[0047] Therefore, when the vehicle needs to move to the left, the inlet of the second chamber 2025 of the lateral movement mechanism 20 corresponding to the left front wheel and left rear wheel is connected to the first connecting pipe 204, and the outlet of the first chamber 2024 is connected to the liquid supply device 10. Similarly, the inlet of the first chamber 2024 of the lateral movement mechanism 20 corresponding to the right front wheel and right rear wheel is connected to the first connecting pipe 204, and the outlet of the second chamber 2025 is connected to the liquid supply device 10. When the vehicle needs to move to the right, the inlet of the first chamber 2024 of the lateral movement mechanism 20 corresponding to the left front wheel and left rear wheel is connected to the first connecting pipe 204, and the outlet of the second chamber 2025 is connected to the liquid supply device 10. Similarly, the inlet of the second chamber 2025 of the lateral movement mechanism 20 corresponding to the right front wheel and right rear wheel is connected to the first connecting pipe 204, and the outlet of the first chamber 2024 is connected to the liquid supply device 10.

[0048] like Figure 1 As shown, the inlet of the first chamber 2024 is connected to the first connecting pipe 204 via the second connecting pipe 206, the inlet of the second chamber 2025 is connected to the first connecting pipe 204 via the third connecting pipe 208, the outlet of the first chamber 2024 is connected to the liquid supply device 10 via the fourth connecting pipe 210, and the outlet of the second chamber 2025 is connected to the liquid supply device 10 via the fifth connecting pipe 212; a second control valve 205 is provided on the second connecting pipe 206, a third control valve 207 is provided on the third connecting pipe 208, a fourth control valve 209 is provided on the fourth connecting pipe 210, and a fifth control valve 211 is provided on the fifth connecting pipe 212.

[0049] The lateral movement device of the present invention can connect one of the inlets of the first chamber 2024 or the second chamber 2025 to the first connecting pipe 204 by controlling the second control valve 205 and the third control valve 207, and connect one of the outlets of the first chamber 2024 and the second chamber 2025 to the liquid supply device 10 by controlling the fourth control valve 209 and the fifth control valve 211. The second control valve 205 and the fifth control valve 211 form one group, and the third control valve 207 and the fourth control valve 209 form another group; at most one group of the two groups of control valves can be in the open state.

[0050] When the second control valve 205 and the fifth control valve 211 are open, the inlet of the first chamber 2024 is connected to the first connecting pipe 204, and the outlet of the second chamber 2025 is connected to the liquid supply device 10. At this time, the third control valve 207 and the fourth control valve 209 are both closed. When the third control valve 207 and the fourth control valve 209 are open, the inlet of the second chamber 2025 is connected to the first connecting pipe 204, and the outlet of the first chamber 2024 is connected to the liquid supply device 10. At this time, the second control valve 205 and the fifth control valve 211 are both closed. When the wheels do not need to move laterally, the first control valve 203 is open, and the second control valve 205, the third control valve 207, the fourth control valve 209, and the fifth control valve 211 are all closed, thus enabling the vehicle height to be raised.

[0051] In such Figure 1 In the illustrated embodiment, the fluid supply device 10 includes a reservoir 101 and a hydraulic pump 102. The hydraulic pump 102 is connected to the reservoir 101. The inlets of the shock absorber 201 and the hydraulic cylinder 202 are connected to the outlet of the hydraulic pump 102, and the outlet of the hydraulic cylinder 202 is connected to the reservoir 101. The inlet of the hydraulic cylinder 202 is the inlet of the first chamber 2024 and the inlet of the second chamber 2025, as described above. The outlet of the hydraulic cylinder 202 is the outlet of the first chamber 2024 and the outlet of the second chamber 2025, as described above. When lateral movement or raising of the vehicle body is required, the hydraulic pump 102 pumps the oil in the reservoir 101 to the shock absorber 201 or the hydraulic cylinder 202.

[0052] In such Figure 1 In the embodiment shown, the lateral movement device further includes a counterweight 30 and a drive mechanism. The counterweight 30 is disposed on the vehicle body, and the drive mechanism is used to drive the counterweight 30 to move along the length direction of the vehicle.

[0053] The counterweight 30 of the present invention is mounted on the frame, and a guide rail 301 is also mounted on the frame. The drive mechanism is used to drive the counterweight 30 to move along the guide rail 301. The drive mechanism of the present invention can be a motor, electric motor, or other structure, and the counterweight 30 and the drive mechanism can be driven directly or through a transmission structure, which will not be elaborated further here.

[0054] In one embodiment, when the front axle wheel 100 moves in the width direction of the vehicle, the counterweight 30 moves rearward; when the rear axle wheel 100 moves in the width direction of the vehicle, the counterweight 30 moves forward. When the left or right front wheel of the front axle moves in the width direction of the vehicle, the counterweight 30 moves rearward to shift the vehicle's center of gravity rearward, thus making it easier for the left or right front wheel to be suspended. Similarly, when the left or right rear wheel of the rear axle moves in the width direction of the vehicle, the counterweight 30 moves forward to shift the vehicle's center of gravity forward, thus making it easier for the left or right rear wheel to be suspended.

[0055] The lateral movement device also includes a controller 40, which is configured such that when the corresponding wheel of one of the multiple lateral movement mechanisms 20 moves along the width direction of the vehicle, the shock absorbers 201 of the other lateral movement mechanisms 20 raise the vehicle body at the corresponding wheel 100. That is, when the left front wheel moves along the width direction of the vehicle, the vehicle body corresponding to the right front wheel, left rear wheel, and right rear wheel is raised by the shock absorbers.

[0056] Specifically, when the vehicle needs to move to the left, taking the left front wheel's lateral movement to the left as an example, the first control valve 203 of the lateral movement mechanism corresponding to the right front wheel, left rear wheel, and right rear wheel opens, while the second control valve 205, third control valve 207, fourth control valve 209, and fifth control valve 211 all close. This lifts the vehicle body at the right front wheel, left rear wheel, and right rear wheel, thereby suspending the left front wheel in the air. The first control valve 203, second control valve 205, and fifth control valve 211 of the lateral movement mechanism corresponding to the left front wheel close, while the third control valve 207 and fourth control valve 209 open, thus achieving the leftward lateral movement of the left front wheel. Taking the lateral movement of the right front wheel to the left as an example, the first control valve 203 of the lateral movement mechanism corresponding to the left front wheel, left rear wheel, and right rear wheel opens, while the second control valve 205, third control valve 207, fourth control valve 209, and fifth control valve 211 are all closed. This lifts the vehicle body at the left front wheel, left rear wheel, and right rear wheel, thus suspending the right front wheel in the air. The first control valve 203, third control valve 207, and fourth control valve 209 of the lateral movement mechanism 20 corresponding to the right front wheel close, while the second control valve 205 and fifth control valve 211 open, enabling the right front wheel to move laterally to the left. Then, the left rear wheel and right rear wheel move laterally to the left. The specific order of the lateral movement of the wheels is not limited.

[0057] In an embodiment of the present invention, the shock absorber 201 includes a housing, a second piston, and a second piston rod. The housing is connected to the wheel 100. The second piston is disposed inside the housing to divide the housing into an upper chamber and a lower chamber. One end of the second piston rod is connected to the second piston, and the other end of the second piston rod is connected to the vehicle body. The fluid supply device 10 is used to supply fluid to the lower chamber. Thus, when the fluid supply device 10 supplies fluid to the lower chamber, the amount of oil in the lower chamber increases, thereby driving the second piston and the second piston rod to move upward, thereby driving the vehicle body connected to the second piston rod to move upward, achieving the purpose of raising the vehicle body.

[0058] The second piston rod is provided with a liquid supply channel. One end of the liquid supply channel is connected to the lower chamber, and the other end is connected to the liquid supply device 10. The second piston rod of this invention integrates a liquid supply channel, eliminating the need for additional holes in the vibration damper, resulting in high reliability and low cost.

[0059] In one embodiment of the present invention, an accumulator 50 is provided on the first connecting pipe 204. The accumulator 50 allows for pre-storage of pressure to enable rapid vehicle height adjustment. The connection point between the hydraulic cylinder 202 and the first connecting pipe 204 is located between the connection point of the accumulator 50 and the first connecting pipe 204 and the first control valve 203. In this way, the power source for the lateral movement of the wheels can also be pre-stored in the accumulator 50 to achieve rapid response for the lateral movement of the vehicle.

[0060] Vehicles equipped with the aforementioned lateral movement device, by incorporating shock absorbers 201 and hydraulic cylinders 202, can simultaneously raise the vehicle and allow the wheels 100 to move in the width direction of the vehicle. The lateral movement of the vehicle can be decomposed into the lateral movement of each wheel, meaning it can be achieved through the lateral movement of each wheel. Thus, when parallel parking, it is only necessary to park the vehicle parallel to the parking space and then use the lateral movement device to complete the parallel parking, significantly reducing the difficulty of parallel parking. Compared to traditional vehicles, vehicles equipped with the lateral movement device can directly achieve lateral movement without repeatedly reversing or adjusting the direction, making operation simple and convenient. Furthermore, the lateral movement device provided by this invention, with its lateral movement mechanism 20, can achieve both vehicle height lifting and lateral movement, sharing the same hydraulic supply device 10 for both functions, simplifying the structure.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
