Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0073] It should be understood that references throughout this specification to "one embodiment" or "an embodiment" mean that a particular feature, structure, or characteristic associated with the embodiment is included in at least one embodiment of the present invention. Therefore, the appearances of "in one embodiment" or "in an embodiment" throughout this specification do not necessarily refer to the same embodiment.

[0075] like Figures 1 to 4 As shown, an embodiment of the present invention discloses a suspension system, which includes a first motor 10 and a first suspension assembly 30. The first motor 10 is used to drive a vehicle, wherein the first motor 10 is connected to the first suspension assembly 30, and the first motor 10 can drive the first suspension assembly 30 to rise and fall.

[0076] like Figures 1 to 4As shown, an embodiment of the utility model discloses a suspension system, which is installed between the body and wheels of a vehicle. The height of the wheels is adjusted through the suspension system to reduce the vibration and impact of uneven road conditions on the body, thereby improving the ride comfort of the vehicle.

[0077] The suspension system disclosed in the embodiment of the present invention includes a first motor 10 and a first suspension assembly 30. The first motor 10 is used to drive the vehicle. In other words, the first motor 10 is the vehicle's main drive motor, capable of driving the wheels. For example, the first motor 10 is connected to a first wheel 50, and the first motor 10 drives the first wheel 50 to rotate.

[0078] It should be noted that the first motor 10 in the embodiment of the present invention is a motor that drives the vehicle. Generally speaking, the first motor 10 refers to the motor of the powertrain. It can be any powertrain motor in hybrid vehicles, extended-range vehicles, and pure electric vehicles. Whether it is a single front-wheel drive motor, a single rear-wheel drive motor, a dual-motor motor, a triple-motor motor, or a quad-motor motor, all fall within the scope of the first motor 10. It is understood that any motor that can participate in driving the vehicle falls within the scope of the vehicle driving motor in this application.

[0079] Furthermore, in the embodiments of the present invention, there are no specific limitations on the type of the first motor 10. The first motor 10 may be a permanent magnet synchronous motor, an asynchronous motor, such as an asynchronous induction motor, an electrically excited synchronous motor, an axial flux motor, or the like. The embodiments of the present invention do not impose any specific limitations on this, and in actual applications, technicians may select the type as needed.

[0080] It should be noted that the first suspension assembly 30 in the embodiment of the present invention is connected between the first wheel 50 and the vehicle body, and the first wheel 50 is driven to rise and fall by the first suspension assembly 30 .

[0081] In this embodiment of the utility model, the first motor 10 is connected to the first suspension assembly 30 to drive the first suspension assembly 30 upwards and downwards. This provides the first suspension assembly 30 with greater power, allowing it to drive the first wheel 50 upwards and downwards, increasing the take-off height of the first wheel 50 and broadening the vehicle's application scenarios. Furthermore, by driving the first suspension assembly 30 with the first motor 10, there is no need for a separate suspension drive motor, resulting in a higher level of integration and lowering costs.

[0082] Alternatively, as Figures 1 to 4As shown, the suspension system in the embodiment of the present invention further includes a first transmission mechanism 20, wherein one end of the first transmission mechanism 20 is connected to the first motor 10, and the other end of the first transmission mechanism 20 is connected to the first suspension assembly 30. The first transmission mechanism 20 connects the first suspension assembly 30 to the first motor 10, so that the first motor 10 can drive the first suspension assembly 30 to rise and fall through the first transmission mechanism 20, thereby driving the first wheel 50 to rise and fall, thereby increasing the wheel's take-off height and expanding the vehicle's application scenarios.

[0083] It can be understood that the first motor 10 in the embodiment of the present invention can not only drive the first suspension assembly 30 to rise and fall through the first transmission mechanism 20, but also drive the first wheel 50 to rotate. For example, the first motor 10 can only drive the first wheel 50 to rotate. Alternatively, the first motor 10 can only drive the first suspension assembly 30 to rise and fall through the first transmission mechanism 20. Alternatively, the first motor 10 can not only drive the first wheel 50 to rotate, but also drive the first suspension assembly 30 to rise and fall through the first transmission mechanism 20. Through the above arrangement, the number of drive motors installed inside the vehicle can be reduced, thereby saving space and reducing costs.

[0084] The suspension system disclosed in the embodiment of the present invention includes a first motor 10, a first transmission mechanism 20, and a first suspension assembly 30. The first motor 10 is used to drive the vehicle and serves as the vehicle's main drive motor. The first motor 10 can also drive the first suspension assembly 30 up and down via the first transmission mechanism 20, providing the first suspension assembly 30 with greater power. The first suspension assembly 30 can then drive the first wheel 50 up and down, allowing the first wheel 50 to have a higher take-off height and a wider range of vehicle applications.

[0085] Furthermore, the first motor 10 in the embodiment of the present invention can not only drive the first wheel 50 to rotate, but also drive the first suspension assembly 30 to rise and fall via the first transmission mechanism 20. This high level of integration eliminates the need for a separate suspension drive motor, thereby reducing the number of drive motors installed within the vehicle, saving space, and lowering costs.

[0086] Alternatively, as Figures 1 to 4 As shown, the suspension system in the embodiment of the present invention also includes a second transmission mechanism 40, wherein one end of the second transmission mechanism 40 is connected to the first motor 10, and the other end is used to connect to the first wheel 50 of the vehicle; the first suspension assembly 30 is used to connect to the first wheel 50.

[0087] like Figures 1 to 4 As shown, one end of the second transmission mechanism 40 is connected to the first motor 10 , and the other end is connected to the first wheel 50 of the vehicle, so that the first motor 10 can drive the first wheel 50 to rotate through the second transmission mechanism 40 .

[0088] It should be noted that the first suspension assembly 30 is connected between the first wheel 50 and the vehicle body, so that the first wheel 50 can be raised and lowered through the first suspension assembly 30, thereby reducing uneven road conditions, vibration and impact on the vehicle body, and improving the ride comfort of the vehicle.

[0089] In this embodiment of the present invention, the first motor 10 can drive the first suspension assembly 30 to rise and fall via the first transmission mechanism 20. The first suspension assembly 30 has greater power, driving the first wheel 50 to rise and fall, thereby increasing the takeoff height of the first wheel 50. Furthermore, the first motor 10 can also drive the first wheel 50 to rotate via the second transmission mechanism 40, thereby reducing the number of drive motors installed within the vehicle, saving space, and lowering costs.

[0090] Alternatively, as Figures 1 to 4 As shown, the first transmission mechanism 20 includes a first on-off component 21, a first speed-changing component 22 and a first transmission shaft 23, wherein the first motor 10 has a first motor shaft 11; the first on-off component 21 and the first speed-changing component 22 are sequentially connected between the first motor shaft 11 and one end of the first transmission shaft 23; the other end of the first transmission shaft 23 is connected to the first suspension assembly 30.

[0091] like Figures 1 to 4 As shown, the first motor 10 in the embodiment of the present invention has a first motor shaft 11. The first transmission mechanism 20 includes a first on-off component 21, a first speed-changing component 22 and a first transmission shaft 23. The first transmission shaft 23 has a first end and a second end that are arranged opposite to each other. The first end of the first transmission shaft 23 is connected to the first suspension assembly 30. The first on-off component 21 and the first speed-changing component 22 are connected between the second end of the first transmission shaft 23 and the first motor shaft 11, so as to control the on-off of the first motor shaft 11 and the first transmission shaft 23 through the first on-off component 21, and adjust the rotation speed of the first transmission shaft 23 through the first speed-changing component 22 so that the rotation speed of the first transmission shaft 23 is larger or smaller than the rotation speed of the first motor shaft 11. For example, the rotation speed of the first motor shaft 11 is larger, and the rotation speed is adjusted by the first speed-changing component 22 so that the rotation speed of the first transmission shaft 23 is smaller.

[0092] It should be noted that the first on / off component 21 in the embodiment of the present invention may be a first clutch, which controls the on / off connection between the first motor shaft 11 and the first transmission shaft 23. The first speed-changing component 22 may be a first transmission or a first reducer. The speed of the first transmission shaft 23 is adjusted by the first transmission or the first reducer.

[0093] Of course, the above is only an example of the specific structure of the first switching component 21 and the first speed changing component 22. It does not limit the present invention. In actual applications, technicians can select appropriate first switching component 21 and first speed changing component 22 as needed.

[0094] In this embodiment of the present invention, the first on / off component 21 controls the on / off switching of the first motor shaft 11 and the first transmission shaft 23, allowing the first motor 10 to drive the first suspension assembly 30 as needed to adjust the takeoff height of the first wheel 50 and enhance vehicle comfort. Furthermore, in this embodiment of the present invention, the first speed-changing component 22 adjusts the rotational speed of the first transmission shaft 23, allowing the rotational speed of the first transmission shaft 23 to be greater or less than that of the first motor shaft 11. This increases the lifting height of the first suspension assembly 30, the takeoff height of the first wheel 50, and enhances vehicle comfort.

[0095] Alternatively, as Figures 1 to 4 As shown, the second transmission mechanism 40 includes a second on-off component 41, a second speed change component 42 and a first drive shaft 43, wherein the second on-off component 41 and the second speed change component 42 are sequentially connected between the first motor shaft 11 and one end of the first drive shaft 41; the other end of the first drive shaft 41 is used to drive the first wheel 50.

[0096] like Figures 1 to 4 As shown, the second transmission mechanism 40 in the embodiment of the present invention includes a second on-off component 41, a second speed change component 42 and a first drive shaft 43. The first drive shaft 43 has a first end and a second end that are arranged opposite to each other. The first end of the first drive shaft 43 is connected to the first wheel 50, and the second on-off component 41 and the second speed change component 42 are connected between the second end of the first drive shaft 43 and the first motor shaft 11, so as to control the on-off of the first motor shaft 11 and the first drive shaft 43 through the second on-off component 41, and adjust the speed of the first drive shaft 43 through the second speed change component 42 so that the speed of the first drive shaft 43 is larger or smaller than the speed of the first motor shaft 11. For example, the speed of the first motor shaft 11 is smaller, and the speed is adjusted by the second speed change component 42 so that the speed of the first drive shaft 43 is larger.

[0097] It should be noted that the second on / off component 41 in the embodiment of the present invention may be a second clutch, which controls the on / off connection between the first motor shaft 11 and the first drive shaft 43. The second speed-changing component 42 may be a second transmission or a second reducer. The speed of the first drive shaft 43 is adjusted by the second transmission or the second reducer.

[0098] Of course, the above is only an example of the specific structure of the second switching component 41 and the second speed changing component 42. It is not intended to limit the present invention. In actual applications, technicians can also select appropriate second switching component 41 and second speed changing component 42 as needed.

[0099] In this embodiment of the present invention, the second on / off component 41 controls the on / off switching of the first motor shaft 11 and the first drive shaft 43, allowing the first motor 10 to drive the first wheel 50 as needed, thereby placing the vehicle in different operating modes. Furthermore, in this embodiment of the present invention, the second speed-changing component 42 adjusts the speed of the first drive shaft 43, making it either faster or slower than the speed of the first motor shaft 11, thereby varying the speed of the first wheel 50 and adjusting the vehicle's travel speed.

[0100] Alternatively, as Figures 1 to 4 As shown, the suspension system disclosed in the embodiment of the present invention also includes a second motor 60 and a second suspension assembly 80. The second motor 60 is used to drive the vehicle, wherein the second motor 60 is connected to the second suspension assembly 80, and the second motor 60 can drive the second suspension assembly 80 to rise and fall.

[0101] like Figures 1 to 4 As shown, the suspension system disclosed in the embodiment of the present invention also includes a second motor 60. It will be understood that the first motor 10 is used to drive the first wheel 50 of the vehicle, and the second motor 60 is used to drive the second wheel 100 of the vehicle. Exemplarily, the first wheel 50 is the left front wheel of the vehicle, and the second wheel 100 is the left rear wheel of the vehicle. The first motor 10 and the second motor 60 are spaced apart along the length of the vehicle, with the first motor 10 connected to the first wheel 50 to drive the first wheel 50, and the second motor 60 connected to the second wheel 100 to drive the second wheel 100.

[0102] The suspension system disclosed in the embodiment of the present invention includes a second motor 60 and a second suspension assembly 80. The second motor 60 is the vehicle's main drive motor, capable of driving the vehicle's second wheel 100. For example, the first motor 10 is connected to the first wheel 50, driving the first wheel 50 to rotate, and the second motor 60 is connected to the second wheel 100, driving the second wheel 100 to rotate.

[0103] It should be noted that the second suspension assembly 80 in the embodiment of the present invention is connected between the second wheel 100 and the vehicle body, and the second wheel 100 is driven to rise and fall by the second suspension assembly 80 .

[0104] In this embodiment of the utility model, the second motor 60 is connected to the first suspension assembly 80 to drive the second suspension assembly 80 upwards and downwards. This provides the second suspension assembly 80 with greater power, allowing it to drive the second wheel 100 upwards and downwards, increasing the take-off height of the second wheel 100 and broadening the vehicle's application scenarios. Furthermore, by using the second motor 60 to drive the second suspension assembly 80, there is no need for a separate suspension drive motor, resulting in a higher level of integration and lowering costs.

[0105] Alternatively, as Figures 1 to 4 As shown, the suspension system in the embodiment of the present invention further includes a third transmission mechanism 70, one end of which is connected to the second motor 60, and the other end of which is connected to the second suspension assembly 80. The second suspension assembly 80 is connected to the second motor 60 via the third transmission mechanism 70, so that the second motor 60 can drive the second suspension assembly 80 to rise and fall via the third transmission mechanism 70, thereby driving the second wheel 100 to rise and fall, thereby increasing the take-off height of the second wheel 100 and expanding the vehicle's application scenarios.

[0106] It will be appreciated that the second motor 60 in the embodiment of the present invention can both drive the second suspension assembly 80 to rise and fall via the third transmission mechanism 70 and also drive the second wheel 100 to rotate. For example, the second motor 60 can only drive the second wheel 100 to rotate. Alternatively, the second motor 60 can only drive the second suspension assembly 80 to rise and fall via the third transmission mechanism 70. Alternatively, the second motor 60 can both drive the second wheel 100 to rotate and, at the same time, drive the second suspension assembly 80 to rise and fall via the third transmission mechanism 70. Through the above arrangement, the number of drive motors installed within the vehicle can be reduced, thereby saving space and reducing costs.

[0107] Alternatively, as Figures 1 to 4 As shown, the suspension system disclosed in the embodiment of the present invention also includes a fourth transmission mechanism 90, wherein one end of the fourth transmission mechanism 90 is connected to the second motor 60, and the other end is used to connect to the second wheel 100 of the vehicle; the second suspension assembly 80 is used to connect to the second wheel 100.

[0108] like Figures 1 to 4 As shown, one end of the fourth transmission mechanism 90 is connected to the second motor 60 , and the other end is connected to the second wheel 100 of the vehicle, so that the second motor 60 can drive the second wheel 100 of the vehicle to rotate through the fourth transmission mechanism 90 .

[0109] It should be noted that the second suspension assembly 80 is connected between the second wheel 100 and the vehicle body, so that the second wheel 100 can be raised and lowered by the second suspension assembly 80, thereby reducing uneven road conditions, vibration and impact on the vehicle body, and improving the ride comfort of the vehicle.

[0110] In this embodiment of the present invention, the second motor 60 can drive the second suspension assembly 80 to rise and fall via the third transmission mechanism 70. This provides greater power for the second suspension assembly 80 to move the second wheel 100 up and down, allowing the second wheel 100 to achieve a higher takeoff height. Furthermore, the second motor 60 can also drive the second wheel 100 to rotate via the fourth transmission mechanism 90, thereby reducing the number of drive motors installed within the vehicle, saving space, and lowering costs.

[0111] Alternatively, as Figures 1 to 4 As shown, the third transmission mechanism 70 in the embodiment of the present invention includes a third on-off component 71, a third speed change component 72 and a second transmission shaft 73, wherein the second motor 60 has a second motor shaft 61; the third on-off component 71 and the third speed change component 72 are sequentially connected between the second motor shaft 61 and one end of the second transmission shaft 73; the other end of the second transmission shaft 73 is connected to the second suspension assembly 80.

[0112] like Figures 1 to 4 As shown, the second motor 60 in the embodiment of the present invention has a second motor shaft 61. The third transmission mechanism 70 includes a third on-off component 71, a third speed-changing component 72, and a second transmission shaft 73. The second transmission shaft 73 has a first end and a second end that are arranged opposite to each other. The first end of the second transmission shaft 73 is connected to the second suspension assembly 80. The third on-off component 71 and the third speed-changing component 72 are connected between the second end of the second transmission shaft 73 and the second motor shaft 61, so as to control the on-off of the second motor shaft 61 and the second transmission shaft 73 through the third on-off component 71, and adjust the speed of the second transmission shaft 73 through the third speed-changing component 72 so that the speed of the second transmission shaft 73 is larger or smaller than the speed of the second motor shaft 61. For example, the speed of the second motor shaft 61 is larger, and the speed is adjusted by the third speed-changing component 72 so that the speed of the second transmission shaft 73 is smaller.

[0113] It should be noted that the third on / off component 71 in the embodiment of the present invention may be a third clutch, which controls the on / off switching of the second motor shaft 61 and the second transmission shaft 73. The third speed-changing component 72 may be a third transmission or a third reducer. The speed of the second transmission shaft 73 is adjusted by the third transmission or the third reducer.

[0114] Of course, the above is only an example of the specific structure of the third switching component 71 and the third speed changing component 72. It does not limit the present invention. In actual application, technicians can select appropriate third switching component 71 and third speed changing component 72 as needed.

[0115] In this embodiment of the present invention, the third on / off component 71 controls the on / off switching of the second motor shaft 61 and the second transmission shaft 73, allowing the second motor 60 to drive the second suspension assembly 80 as needed to adjust the take-off height of the second wheel 100 and enhance vehicle comfort. Furthermore, in this embodiment of the present invention, the third speed-changing component 72 adjusts the speed of the second transmission shaft 73, allowing the speed of the second transmission shaft 73 to be higher or lower than the speed of the second motor shaft 61. This increases the lifting height of the second suspension assembly 80, the take-off height of the second wheel 100, and enhances vehicle comfort.

[0116] Alternatively, as Figures 1 to 4 As shown, the fourth transmission mechanism 90 in the embodiment of the present invention includes a fourth on-off component 91, a fourth speed change component 92 and a second drive shaft 93, wherein the fourth on-off component 91 and the fourth speed change component 92 are sequentially connected between the second motor shaft 61 and one end of the second drive shaft 93; the other end of the second drive shaft 93 is used to drive the second wheel 100.

[0117] like Figures 1 to 4 As shown, the fourth transmission mechanism 90 in the embodiment of the present invention includes a fourth on-off component 91, a fourth speed change component 92, and a second drive shaft 93. The second drive shaft 93 has a first end and a second end that are arranged opposite to each other. The first end of the second drive shaft 93 is connected to the second wheel 100. The fourth on-off component 91 and the fourth speed change component 92 are connected between the second end of the second drive shaft 93 and the second motor shaft 61, so as to control the on-off of the second motor shaft 61 and the second drive shaft 93 through the fourth on-off component 91, and adjust the speed of the second drive shaft 93 through the fourth speed change component 92 so that the speed of the second drive shaft 93 is larger or smaller than the speed of the second motor shaft 61. For example, the speed of the second motor shaft 61 is smaller, and the speed is adjusted by the fourth speed change component 92 so that the speed of the second drive shaft 93 is larger.

[0118] It should be noted that the fourth on / off component 91 in the embodiment of the present invention may be a fourth clutch, which controls the on / off switching of the second motor shaft 61 and the second drive shaft 93. The fourth speed-changing component 92 may be a fourth transmission or a fourth reducer. The speed of the second drive shaft 93 is adjusted by the fourth transmission or the fourth reducer.

[0119] Of course, the above is only an example of the specific structure of the fourth switching component 91 and the fourth speed change component 92. It does not limit the present invention. In actual application, technicians can also select appropriate fourth switching component 91 and fourth speed change component 92 according to their needs.

[0120] In this embodiment of the present invention, the fourth on / off component 91 controls the on / off switching of the second motor shaft 61 and the second drive shaft 93, allowing the second motor 60 to drive the second wheel 100 as needed, thereby placing the vehicle in different operating modes. Furthermore, in this embodiment of the present invention, the fourth speed-changing component 92 adjusts the speed of the second drive shaft 93, making it either faster or slower than the speed of the second motor shaft 61, thereby varying the speed of the second wheel 100 and adjusting the vehicle's travel speed.

[0121] Alternatively, as Figures 1 to 4 As shown, the suspension system disclosed in the embodiment of the present invention further includes a fifth on-off component 110 , one end of the fifth on-off component 110 is connected to the second suspension assembly 80 , and the other end is connected to the first motor 10 .

[0122] like Figures 1 to 4 As shown, in this embodiment of the present invention, a fifth on-off component 110 is connected between the second suspension assembly 80 and the first motor 10. Specifically, one end of the fifth on-off component 110 is connected to the second suspension assembly 80, and the other end is connected to the first motor 10. This allows the fifth on-off component 110 to control the on / off switching of the second suspension assembly 80 and the first motor 10. When the fifth on-off component 110 is connected to the second suspension assembly 80 and the first motor 10, the energy generated by the movement of the second suspension assembly 80 can be transferred to the first motor 10, which then recovers the energy.

[0123] For example, Figures 1 to 4 As shown, one end of the fifth switching component 110 can be connected between the third switching component 71 and the third speed change component 72, and the other end can be connected to the first motor shaft 11. One end of the fifth switching component 110 can also be connected between the third speed change component 72 and the second suspension assembly 80, and the other end can be connected to the first motor shaft 11. In the embodiment of the present invention, there is no specific limitation to this. In actual applications, technicians can set it as needed.

[0124] The suspension system disclosed in the embodiments of the present invention has multiple on / off states. Depending on the on / off state of the suspension system, the vehicle operates in different modes. This also allows for a high level of integration within the suspension drive assembly disclosed in the embodiments of the present invention. The following description of the vehicle's operating modes will use the example of a first wheel 50 being the left front wheel and a second wheel 100 being the left rear wheel as an example.

[0125] It should be noted that the third wheel 220 may be the right front wheel of the vehicle, and the fourth wheel 270 may be the right rear wheel of the vehicle. When the vehicle is in different operating modes, the operating states of the third suspension assembly 190 and the third wheel 220 are similar to those of the first suspension assembly 30 and the first wheel 50, respectively. The operating states of the fourth suspension assembly 240 and the fourth wheel 270 are similar to those of the second suspension assembly 80 and the second wheel 100, respectively. Extensive details will not be given here.

[0126] Optionally, when the vehicle is in the first mode, which means that the vehicle is in energy recovery mode and rear-wheel drive, the first on-off component 21 disconnects the connection between the first motor shaft 11 and the first transmission shaft 23, and the second on-off component 41 disconnects the connection between the first motor shaft 11 and the first drive shaft 43; the third on-off component 71 disconnects the connection between the second motor shaft 61 and the second transmission shaft 73, and the fourth on-off component 91 connects the second motor shaft 61 and the second drive shaft 93; the fifth on-off component 110 connects the first motor 10 and the second suspension assembly 80.

[0127] The vehicle has a first mode, which is an energy recovery mode, and is rear-wheel drive. When the vehicle is in energy recovery mode and rear-wheel drive, the first disconnect component 21 disconnects the first motor shaft 11 and the first transmission shaft 23, and the second disconnect component 41 disconnects the first motor shaft 11 and the first drive shaft 43. This means that the first drive shaft 23 does not drive the first suspension assembly 30 up or down, and the first drive shaft 43 does not drive the first wheel 50 to rotate. The third disconnect component 71 disconnects the second motor shaft 61 and the second transmission shaft 73, and the fourth disconnect component 91 connects the second motor shaft 61 and the second drive shaft 93. This means that the second transmission shaft 73 does not drive the second suspension assembly 80 up or down, while the second drive shaft 93 drives the second wheel 100 to rotate. The fifth disconnect component 110 connects the first motor 10 and the second suspension assembly 80. Energy generated by the vibration of the second suspension assembly 80 is transferred to the first motor 10, where it is recovered.

[0128] Optionally, when the vehicle is in the first mode, which means that the vehicle is in energy recovery mode and rear-wheel drive, the first on-off component 21 connects the first motor shaft 11 and the first transmission shaft 23, and the second on-off component 41 disconnects the connection between the first motor shaft 11 and the first drive shaft 43; the third on-off component 71 disconnects the connection between the second motor shaft 61 and the second transmission shaft 73, and the fourth on-off component 91 connects the second motor shaft 61 and the second drive shaft 93; the fifth on-off component 110 disconnects the connection between the first motor 10 and the second suspension assembly 80.

[0129] The vehicle has a first mode, which is an energy recovery mode, and is rear-wheel drive. When the vehicle is in the first mode, i.e., energy recovery mode with rear-wheel drive, the first disconnect component 21 connects the first motor shaft 11 and the first transmission shaft 23, and the second disconnect component 41 disconnects the first motor shaft 11 and the first drive shaft 43. This means that the first drive shaft 23 drives the first suspension assembly 30 up and down, while the first drive shaft 43 does not drive the first wheel 50 to rotate. The third disconnect component 71 disconnects the second motor shaft 61 and the second transmission shaft 73, and the fourth disconnect component 91 connects the second motor shaft 61 and the second drive shaft 93. This means that the second transmission shaft 73 does not drive the second suspension assembly 80 up and down, while the second drive shaft 93 drives the second wheel 100 to rotate. The fifth disconnect component 110 disconnects the first motor 10 and the second suspension assembly 80, allowing the energy generated by the vibration of the first suspension assembly 30 to be transferred to the first motor 10, where it is recovered.

[0130] Optionally, when the vehicle is in the first mode, which means that the vehicle is in energy recovery mode and is front-wheel drive, the first on-off component 21 disconnects the connection between the first motor shaft 11 and the first transmission shaft 23, and the second on-off component 41 connects the first motor shaft 11 and the first drive shaft 43; the third on-off component 71 connects the second motor shaft 61 and the second transmission shaft 73, and the fourth on-off component 91 disconnects the connection between the second motor shaft 61 and the second drive shaft 93; the fifth on-off component 110 disconnects the connection between the first motor 10 and the second suspension assembly 80.

[0131] The vehicle has a first mode, which is when the vehicle is in energy recovery mode and front-wheel drive. When the vehicle is in energy recovery mode and front-wheel drive, the first on-off component 21 disconnects the first motor shaft 11 and the first transmission shaft 23, and the second on-off component 41 connects the first motor shaft 11 and the first drive shaft 43. This means that the first drive shaft 23 does not drive the first suspension assembly 30 up or down, while the first drive shaft 43 drives the first wheel 50 to rotate. The third on-off component 71 connects the second motor shaft 61 and the second transmission shaft 73, and the fourth on-off component 91 disconnects the second motor shaft 61 and the second drive shaft 93. This means that the second transmission shaft 73 drives the second suspension assembly 80 up or down, while the second drive shaft 93 does not drive the second wheel 100 to rotate. The fifth on-off component 110 disconnects the first motor 10 and the second suspension assembly 80, allowing the energy generated by the vibration of the second suspension assembly 80 to be transferred to the second motor 60 for energy recovery.

[0132] Optionally, when the vehicle is in the second mode, which means that the vehicle is in the take-off mode, the first on-off component 21 connects the first motor shaft 11 and the first transmission shaft 23, and the second on-off component 41 disconnects the connection between the first motor shaft 11 and the first drive shaft 43; the third on-off component 71 connects the second motor shaft 61 and the second transmission shaft 73, and the fourth on-off component 91 disconnects the connection between the second motor shaft 61 and the second drive shaft 93; the fifth on-off component 110 disconnects the connection between the first motor 10 and the second suspension assembly 80.

[0133] The vehicle has a second mode, which is referred to as a take-off mode. When the vehicle is in take-off mode, the first on-off component 21 connects the first motor shaft 11 and the first transmission shaft 23, and the second on-off component 41 disconnects the first motor shaft 11 and the first drive shaft 43. That is, the first drive shaft 23 drives the first suspension assembly 30 to rise and fall, and the first drive shaft 43 does not drive the first wheel 50 to rotate. The third on-off component 71 connects the second motor shaft 61 and the second transmission shaft 73, and the fourth on-off component 91 disconnects the second motor shaft 61 and the second drive shaft 93. That is, the second transmission shaft 73 drives the second suspension assembly 80 to rise and fall, and the second drive shaft 93 does not drive the second wheel 100 to rotate. The fifth on-off component 110 disconnects the first motor 10 and the second suspension assembly 80, and energy recovery is not performed.

[0134] When the vehicle is in take-off mode, it enters a static or inertial driving state. The first transmission shaft 23 drives the first suspension assembly 30 up and down, while the second transmission shaft 73 drives the second suspension assembly 80 up and down. All the energy from the first motor 10 is used to drive the first suspension assembly 30 up and down, while all the energy from the second motor 60 is used to drive the second suspension assembly 80 up and down. This provides greater driving force for the first and second suspension assemblies 30 and 80, enabling the vehicle to take off from the spot and enhance its ability to leap over obstacles.

[0135] Optionally, the vehicle has a third mode, which is when the vehicle is in four-wheel drive mode. When the vehicle is in four-wheel drive mode, the first on-off component 21 disconnects the first motor shaft 11 and the first transmission shaft 23, and the second on-off component 41 connects the first motor shaft 11 and the first drive shaft 43. The third on-off component 71 disconnects the second motor shaft 61 and the second transmission shaft 73, and the fourth on-off component 91 connects the second motor shaft 61 and the second drive shaft 93. The fifth on-off component 110 disconnects the first motor 10 and the second suspension assembly 80.

[0136] The vehicle has a third mode, which indicates that the vehicle is in four-wheel drive mode. When the vehicle is in four-wheel drive mode, the first on-off component 21 disconnects the first motor shaft 11 and the first transmission shaft 23, and the second on-off component 41 connects the first motor shaft 11 and the first drive shaft 43. In other words, the first drive shaft 23 does not drive the first suspension assembly 30 to rise or fall, and the first drive shaft 43 drives the first wheel 50 to rotate. The third on-off component 71 disconnects the second motor shaft 61 and the second transmission shaft 73, and the fourth on-off component 91 connects the second motor shaft 61 and the second drive shaft 93. In other words, the second transmission shaft 73 does not drive the second suspension assembly 80 to rise or fall, and the second drive shaft 93 drives the second wheel 100 to rotate. The fifth on-off component 110 disconnects the first motor 10 and the second suspension assembly 80, and energy recovery is not performed.

[0137] When the vehicle is in the four-wheel drive mode, the first motor 10 drives the first wheel 50 to rotate, and the second motor 60 drives the second wheel 100 to rotate, so as to increase the vehicle speed.

[0139] When the vehicle is in this mode, the first on / off component 21 disconnects the first motor shaft 11 and the first transmission shaft 23, while the second on / off component 41 connects the first motor shaft 11 and the first drive shaft 43. This means that the first drive shaft 23 does not drive the first suspension assembly 30 up or down, while the first drive shaft 43 drives the first wheel 50 to rotate. The third on / off component 71 connects the second motor shaft 61 and the second transmission shaft 73, while the fourth on / off component 91 disconnects the second motor shaft 61 and the second drive shaft 93. This means that the second transmission shaft 73 drives the second suspension assembly 80 up or down, while the second drive shaft 93 does not drive the second wheel 100 to rotate. The fifth on / off component 110 connects the first motor 10 and the second suspension assembly 80. The energy generated by the vibration of the second suspension assembly 80 can be transferred to the first motor 10, where it can be recovered.

[0140] When the vehicle is in this mode, the second motor 60 drives the second suspension assembly 80 to rise and fall, while the first motor 10 drives the first wheel 50 to rotate, ensuring greater interior comfort under varying road conditions. Furthermore, the energy generated by the vibration of the second suspension assembly 80 can be transferred to the first motor 10 for energy recovery.

[0142] When the vehicle is in this mode, the first on / off component 21 connects the first motor shaft 11 and the first transmission shaft 23, while the second on / off component 41 disconnects the first motor shaft 11 and the first drive shaft 43. This means that the first drive shaft 23 drives the first suspension assembly 30 up and down, while the first drive shaft 43 does not drive the first wheel 50. The third on / off component 71 disconnects the second motor shaft 61 and the second transmission shaft 73, while the fourth on / off component 91 connects the second motor shaft 61 and the second drive shaft 93. This means that the second transmission shaft 73 does not drive the second suspension assembly 80 up and down, while the second drive shaft 93 drives the second wheel 100. The fifth on / off component 110 connects the first motor 10 and the second suspension assembly 80.

When the first transmission mechanism 20 is connected to the first suspension assembly 30 and the first motor 10, the power of the first motor 10 can be transmitted to the first bidirectional hydraulic pump 120 through the first transmission mechanism 20. The first bidirectional hydraulic pump 120 changes the pressure in the upper and lower chambers of the shock absorber in the first suspension assembly 30 by rotating forward and reverse, thereby driving the shock absorber piston rod to rise and fall, thereby driving the first wheel 50 to rise and fall.

When the first transmission mechanism 20 is connected to the first suspension assembly 30 and the first motor 10, the power of the first motor 10 can be transmitted to the first ball screw assembly 160 through the first transmission mechanism 20. The first ball screw assembly 160 is connected to the piston rod of the shock absorber in the first suspension assembly 30. By controlling the rotation direction of the balls in the first ball screw assembly 160, the shock absorber piston rod is driven to rise and fall, thereby driving the first wheel 50 to rise and fall.
