Description

Technical Field

[0001] The present disclosure relates to the field of vehicle driving technology, and in particular to a driving system and a vehicle. Background Art

[0002] At present, there are a large number of loads driven by electric motors in vehicles, such as windows, seats, door locks, etc. These loads have the characteristics of short working time and high power when working. For example, the seats are adjusted less frequently during use and the time of each adjustment is short, which makes the motor used for seat adjustment less frequently used. In addition, since the seats themselves and the load are large, the work done by the motor used for seat adjustment is large during operation. Therefore, the motor needs to be designed with a larger power, which leads to low overall efficiency. The large energy consumption of the motor also leads to a higher overall cost of use. At the same time, since the motor needs to arrange more control lines, power lines and other wiring harnesses and control devices such as controllers and servers, the overall space occupied is also large.

[0045] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0046] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0047] like Figure 1 As shown, an embodiment of the present disclosure proposes a driving system, including an air source 1 and at least one air circuit module 2, the air circuit module 2 includes a main air circuit 21 and at least one branch unit 22, the air inlet end of the main air circuit 21 is connected to the air outlet end of the air source 1, the branch unit 22 includes a branch air circuit 221, a pneumatic component 222 and a first control valve 223, the air inlet end of the branch air circuit 221 is connected to the first air outlet end of the main air circuit 21, the air outlet end of the branch air circuit 221 is connected to the air inlet end of the pneumatic component 222, the pneumatic component 222 is used to drive a load 3 of the vehicle, the first control valve 223 is arranged between the air outlet end of the branch air circuit 221 and the air inlet end of the pneumatic component 222, and the first control valve 223 is used to selectively open the passage between the air outlet end of the branch air circuit 221 and the air inlet end of the pneumatic component 222.

[0048] It can be understood that since the air inlet end of the main air circuit 21 is connected to the air outlet end of the air source 1, the air inlet end of the branch air circuit 221 is connected to the first air outlet end of the main air circuit 21, and the air outlet end of the branch air circuit 221 is connected to the air inlet end of the pneumatic component 222, the compressed air output by the air source 1 can pass through the main air circuit 21 and the branch air circuit 221 in sequence and enter the pneumatic component 222, so that the pneumatic component 222 can use the compressed air to operate, and since the first control valve 223 is arranged between the air outlet end of the branch air circuit 221 and the air inlet end of the pneumatic component 222 and selectively opens the passage between the air outlet end of the branch air circuit 221 and the air inlet end of the pneumatic component 222, when the drive system is applied to a vehicle, the first control valve 223 can be used to control the operation of the pneumatic component 222, thereby controlling the load 3 of the vehicle to meet the movement requirements of the load 3 of the vehicle.

[0049] Since the pneumatic component 222 utilizes compressed air to output kinetic energy, and the whole only involves the control of the first control valve 223, the overall design power of the drive system is relatively low. Therefore, even when the drive system is not used frequently, the whole has a relatively high overall efficiency. At the same time, since the drive system utilizes the air source 1 for centralized supply of compressed air, and the whole only involves power loss at the air source 1 and the first control valve 223, the overall energy consumption is greatly reduced. Moreover, the pneumatic component 222 only involves the main air circuit 21 and the branch air circuit 221 as well as the wiring harness for controlling the first control valve 223, which greatly reduces the overall wiring harness and control devices, thereby effectively reducing the occupied space of the drive system and reducing the use cost of the drive system.

[0050] Among them, since the pneumatic component 222 uses compressed air to output kinetic energy, the pneumatic component 222 has the characteristics of small dead zone of movement, no overload burning, strong temperature adaptability, easy maintenance, high integration, and light weight compared to the electric motor. This not only reduces the size and weight of the drive system, but also makes the drive system more reliable and safe, and has a lower cost of use.

[0051] Since the control of the pneumatic component 222 is relatively simple, not only the control power consumption of the drive system is greatly reduced, the control wiring harness is greatly reduced, so that when the drive system is used in the vehicle, it is beneficial to improve the vehicle's EMC (Electromagnetic Compatibility) and EMI (Electromagnetic Interference) environment, thereby improving the control efficiency of the entire vehicle. In addition, when the drive system is used in the vehicle, it can also greatly reduce the high-power drive circuit on the BCM (Body Control Module), thereby reducing the device cost and heat dissipation cost of the BCM, and at the same time facilitating the layout of the BCM.

[0052] It should be noted that the gas source 1 refers to a source for providing compressed air. The specific type of the gas source 1 can be set according to actual needs and is not limited to this. For example, the gas source 1 can be a gas tank 11 filled with compressed air, an air compressor 14, etc.

[0053] The number of gas circuit modules 2 can be set according to actual needs and is not limited to this. For example, the gas circuit modules 2 can be one, two, three, four, etc., wherein, when there are multiple gas circuit modules 2, the main gas circuits 21 of the multiple gas circuit modules 2 are respectively provided with compressed air by the gas source 1.

[0054] The main air circuit 21 is used for transferring compressed air. The specific type of the main air circuit 21 can be set according to actual needs and is not limited to this. For example, the main air circuit 21 can be an air pipe. The main air circuit 21 includes a second air outlet end and multiple first air outlet ends. The first air outlet end is used to be connected to the air inlet end of the branch air circuit 221, and the second air outlet end is used to discharge excess compressed air.

[0055] The number of branch units 22 can be set according to actual needs and is not limited to this. For example, the branch unit 22 can be one, two, three, four, etc., wherein, when there are multiple branch units 22, the branch air circuits 221 of the multiple branch units 22 are respectively provided with compressed air by the main air circuit 21.

[0056] The branch air path 221 is used for transferring compressed air. The specific type of the branch air path 221 can be set according to actual needs and is not limited to this. For example, the branch air path 221 can be a trachea.

[0057] The pneumatic component 222 is used to output kinetic energy using compressed air. The specific type of the pneumatic component 222 can be set according to actual needs and is not limited to this. For example, the pneumatic component 222 can be a pneumatic component such as a cylinder and a pneumatic motor 22224, or it can be a driving structure composed of multiple pneumatic components such as a cylinder and a pneumatic motor 22224.

[0058] The first control valve 223 is used to control the on-off of the passage between the branch air path 221 and the pneumatic component 222. The specific type of the first control valve 223 can be set according to actual needs and is not limited to this. For example, the first control valve 223 can be a switch valve, a two-position three-way valve, a three-position five-way valve, etc.

[0059] The load 3 of the vehicle refers to the functional components that need to move in the vehicle. The specific type of the load 3 can be set according to actual needs and is not limited to this. For example, the load 3 can be a seat 31, a door lock 32, a window 33, a wiper 34, a tailgate 35, a beam 36 and an axle 37, etc.

[0060] like Figure 2 As shown, in some embodiments, the gas source 1 includes a gas tank 11 and a second control valve 12, the gas outlet end of the gas tank 11 is connected to the gas inlet end of the main gas circuit 21, and the second control valve 12 is arranged between the gas outlet end of the gas tank 11 and the gas inlet end of the main gas circuit 21, and the second control valve 12 is used to selectively open the passage between the gas outlet end of the gas tank 11 and the gas inlet end of the main gas circuit 21.

[0061] It can be understood that since the air inlet end of the main air circuit 21 is connected to the air outlet end of the air tank 11, the compressed air output by the air tank 11 can pass through the main air circuit 21 and the branch air circuit 221 in sequence and then enter the pneumatic component 222, so that the pneumatic component 222 can use the compressed air to operate, and since the second control valve 12 is arranged between the air outlet end of the air tank 11 and the air inlet end of the main air circuit 21 and selectively opens the passage between the air outlet end of the air tank 11 and the air inlet end of the main air circuit 21, the second control valve 12 can cooperate with the first control valve 223 to control the operation of the pneumatic component 222. Therefore, when the drive system is applied to a vehicle, the operation of the pneumatic component 222, the first control valve 223 and the second control valve 12 can be used to meet the movement requirements of the vehicle's load 3.

[0062] It should be noted that the air tank 11 serves as the air source 1 to output compressed air to the main air circuit 21. The specific type of the air tank 11 can be set according to actual needs and is not limited to this. For example, the air tank 11 can be a tank structure, and the air tank 11 is filled with air with a certain pressure. When the second control valve 12 is opened, the air tank 11 outputs compressed air to the main air circuit 21. When the second control valve 12 is closed, the air tank 11 stops outputting compressed air to the main air circuit 21.

[0063] When the compressed air in the air storage tank 11 is insufficient, the air storage tank 11 may be replaced, or other equipment may be used to supply compressed air to the air storage tank 11, and there is no limitation to this.

[0064] The second control valve 12 is used to control the on-off of the passage between the gas storage tank 11 and the main gas path 21. The specific type of the second control valve 12 can be set according to actual needs and is not limited to this. For example, the second control valve 12 can be a switch valve.

[0065] like Figure 2 As shown, in some embodiments, the gas source 1 also includes a first air pressure sensor 13, an air compressor 14 and a third control valve 15. The detection end of the first air pressure sensor 13 is arranged in the gas storage tank 11, the gas outlet end of the air compressor 14 is connected to the gas inlet end of the gas storage tank 11, and the third control valve 15 is arranged between the gas outlet end of the air compressor 14 and the gas inlet end of the gas storage tank 11. The third control valve 15 is used to selectively open the passage between the gas outlet end of the air compressor 14 and the gas inlet end of the gas storage tank 11.

[0066] It can be understood that since the detection end of the first air pressure sensor 13 is arranged in the air tank 11, the drive system can use the first air pressure sensor 13 to detect the air pressure in the air tank 11, and since the air outlet end of the air compressor 14 is connected to the air inlet end of the air tank 11, the third control valve 15 is arranged between the air outlet end of the air compressor 14 and the air inlet end of the air tank 11 and selectively opens the passage between the air outlet end of the air compressor 14 and the air inlet end of the air tank 11, so that when the air pressure in the air tank 11 is lower than the set threshold value, the drive system can use the opening of the third control valve 15 and the air compressor 14 to replenish compressed air into the air tank 11, so that the air pressure in the air tank 11 is maintained above the set threshold value, thereby ensuring the stable air supply from the air tank 11 to the pneumatic component 222.

[0067] At the same time, by using the air storage tank 11 as a transfer component for compressed air, it can also buffer the compressed air output by the air compressor 14 to ensure that the compressed air pressure input by the pneumatic component 222 is more stable. At the same time, it can also reduce the starting frequency of the air compressor 14, thereby extending the service life of the air compressor 14 and reducing the use cost of the drive system.

[0068] It should be noted that the first air pressure sensor 13 is used to detect the air pressure in the air storage tank 11. The specific type of the first air pressure sensor 13 can be set according to actual needs and is not limited to this.

[0069] The air compressor 14 is an air compressor, and the air compressor 14 is used to compress air according to the input electrical energy or kinetic energy. The specific type of the air compressor 14 can be set according to actual needs and is not limited to this.

[0070] The third control valve 15 is used to control the on-off of the passage between the air compressor 14 and the air storage tank 11. The specific type of the third control valve 15 can be set according to actual needs and is not limited to this. For example, the third control valve 15 can be a switch valve, etc.

[0071] The second control valve 12 and the third control valve 15 operate independently. When the pneumatic component 222 needs to be actuated, the second control valve 12 is opened. When the air pressure in the air storage tank 11 is insufficient, the third control valve 15 is opened.

[0072] The first control valve 223, the second control valve 12 and the third control valve 15 may be controlled by a controller, and the specific type of the controller may be set according to actual needs and is not limited thereto. For example, the controller may be a BCM of the vehicle.

[0073] The threshold value of the air pressure in the air storage tank 11 can be set according to actual needs and is not limited thereto.

[0074] like Figure 2As shown, in some embodiments, the gas source 1 also includes an engine 16 and / or a battery 17, the power output end of the engine 16 is connected to the power input end of the air compressor 14, and the power output end of the battery 17 is connected to the power input end of the air compressor 14.

[0075] It can be understood that since the power output end of the engine 16 is connected to the power input end of the air compressor 14, the engine 16 can provide kinetic energy to the air compressor 14, so that the air compressor 14 can operate and generate compressed air to be output to the air tank 11, thereby ensuring that the air tank 11 provides a stable air supply to the pneumatic component 222.

[0076] Since the power output end of the battery 17 is connected to the power input end of the air compressor 14, the battery 17 can provide electrical energy to the air compressor 14, so that the air compressor 14 can operate and generate compressed air to be output to the air tank 11, thereby ensuring that the air tank 11 provides a stable air supply to the pneumatic component 222.

[0077] It should be noted that the engine 16 is a machine for converting other forms of energy into kinetic energy. The specific type of the engine 16 can be set according to actual needs and is not limited to this. For example, the engine 16 can be an engine 16 in a vehicle.

[0078] The battery 17 is a device for converting chemical energy into electrical energy. The specific type of the battery 17 can be set according to actual needs and is not limited to this. For example, the battery 17 can be a battery 17 in a vehicle.

[0079] According to actual use requirements, the gas source 1 may include only the engine 16, the gas source 1 may include only the battery 17, or the gas source 1 may include both the engine 16 and the battery 17, and there is no limitation to this.

[0080] like Figure 3 and Figure 4 As shown, in some embodiments, the pneumatic component 222 includes a first drive component 2221, the air inlet end of the first drive component 2221 is connected to the air outlet end of the branch circuit 221, the drive end of the first drive component 2221 moves in a straight line, and the first control valve 223 is arranged between the air outlet end of the branch circuit 221 and the air inlet end of the first drive component 2221.

[0081] It can be understood that the compressed air output by the air source 1 passes through the main air path 21 and the branch air path 221 in sequence and then enters the first drive component 2221. The drive end of the first drive component 2221 uses compressed air to perform linear motion. Therefore, when the drive system is applied to a vehicle, the first drive component 2221 can be used to drive the load 3 to perform linear motion, rotational motion, and the like, thereby meeting the movement requirements of the load 3 of the vehicle.

[0082] It should be noted that the first driving component 2221 is used to utilize compressed air to make its driving end perform linear motion. The specific type of the first driving component 2221 can be set according to actual needs and is not limited to this.

[0083] The first driving component 2221 can drive the load 3 to perform linear motion, or can drive the load 3 to perform rotational motion, swinging motion, etc. with the help of a transmission mechanism, and there is no limitation to this.

[0084] like Figure 3 and Figure 4 As shown, in some embodiments, the first driving assembly 2221 includes a first linear cylinder 22211, and the first control valve 223 is a three-position five-way valve;

[0085] The rodless chamber ventilation end of the first linear cylinder 22211 is connected to the first end of the first control valve 223, and the third end of the first control valve 223 is connected to the outlet end of the branch gas path 221, wherein the first end of the first control valve 223 is connected to the second end of the first control valve 223, or the first end of the first control valve 223 is connected to the third end of the first control valve 223;

[0086] And / or the rod chamber ventilation end of the first linear cylinder 22211 is connected to the fourth end of the first control valve 223, and the third end of the first control valve 223 is connected to the outlet end of the branch air path 221, wherein the fourth end of the first control valve 223 is connected to the third end of the first control valve 223, or the fourth end of the first control valve 223 is connected to the fifth end of the first control valve 223.

[0087] It can be understood that, since the first control valve 223 is a three-position five-way valve, the first control valve 223 has five ports, namely the first end, the second end, the third end, the fourth end and the fifth end. When the first end of the first control valve 223 is connected to the second end of the first control valve 223, since the rodless chamber ventilation end of the first linear cylinder 22211 is connected to the first end of the first control valve 223, the rodless chamber of the first linear cylinder 22211 can be exhausted by the first control valve 223, so that the first linear cylinder 22211 can be exhausted by the first control valve 223. The piston rod of the cylinder 22211 can retract; when the first end of the first control valve 223 is connected to the third end of the first control valve 223, since the rodless chamber ventilation end of the first linear cylinder 22211 is connected to the first end of the first control valve 223, and the third end of the first control valve 223 is connected to the outlet end of the branch air path 221, the compressed air in the branch air path 221 can enter the rodless chamber of the first linear cylinder 22211, thereby driving the piston rod of the first linear cylinder 22211 to extend. Thus, by controlling the first control valve 223, the first linear cylinder 22211 can retract.

[0088] When the fourth end of the first control valve 223 is connected to the third end of the first control valve 223, since the rod chamber ventilation end of the first linear cylinder 22211 is connected to the fourth end of the first control valve 223, the third end of the first control valve 223 is connected to the outlet end of the branch air path 221, so that the compressed air in the branch air path 221 can enter the rod chamber of the first linear cylinder 22211, thereby driving the piston rod of the first linear cylinder 22211 to retract; when the fourth end of the first control valve 223 is connected to the fifth end of the first control valve 223, since the rod chamber ventilation end of the first linear cylinder 22211 is connected to the fourth end of the first control valve 223, the rod chamber of the first linear cylinder 22211 can be exhausted by the first control valve 223, thereby allowing the piston rod of the first linear cylinder 22211 to extend. Therefore, by controlling the first control valve 223, the first linear cylinder 22211 can perform telescopic action.

[0089] It should be noted that when only the rodless chamber ventilation end of the first linear cylinder 22211 is connected to the first end of the first control valve 223, and the third end of the first control valve 223 is connected to the outlet end of the branch air path 221, the first linear cylinder 22211 can use compressed air to extend the piston rod, and the retraction of the piston rod of the first linear cylinder 22211 can be driven by other means, such as manpower, the deadweight of the load 3, the spring in the load 3, etc. Among them, the first control valve 223 can be regarded as a two-position three-way valve.

[0090] When only the rod chamber ventilation end of the first linear cylinder 22211 is connected to the fourth end of the first control valve 223, and the third end of the first control valve 223 is connected to the outlet end of the branch air path 221, the first linear cylinder 22211 can use compressed air to retract the piston rod, and the extension of the piston rod of the first linear cylinder 22211 can be driven by other means, such as manpower, the deadweight of the load 3, the spring in the load 3, etc. Among them, the first control valve 223 can be regarded as a two-position three-way valve.

[0091] At the same time, the rodless chamber ventilation end of the first linear cylinder 22211 is connected to the first end of the first control valve 223, and the third end of the first control valve 223 is connected to the air outlet end of the branch air path 221, and the rod chamber ventilation end of the first linear cylinder 22211 is connected to the fourth end of the first control valve 223, and the third end of the first control valve 223 is connected to the air outlet end of the branch air path 221. At this time, the first linear cylinder 22211 can use compressed air to extend and retract the piston rod.

[0092] Among them, when the first control valve 223 is in the first open state, the first end is connected to the third end, and the fourth end is connected to the fifth end. At this time, the compressed air in the branch air circuit 221 can enter the rodless chamber of the first linear cylinder 22211, and the rod chamber of the first linear cylinder 22211 can be exhausted by the first control valve 223, thereby making the piston rod of the first linear cylinder 22211 extend under the drive of compressed air; when the first control valve 223 is in the second open state, the first end is connected to the second end, and the fourth end is connected to the third end. At this time, the rodless chamber of the first linear cylinder 22211 can be exhausted by the first control valve 223, and the compressed air in the branch air circuit 221 can enter the rod chamber of the first linear cylinder 22211, thereby making the piston rod of the first linear cylinder 22211 retract under the drive of compressed air. Thus, when the first control valve 223 is switched between the first open state and the second open state, the extension and retraction action of the piston rod of the first linear cylinder 22211 can be realized.

[0093] like Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, in some embodiments, the pneumatic component 222 includes a second drive component 2222, the air inlet end of the second drive component 2222 is connected to the air outlet end of the branch circuit 221, the drive end of the second drive component 2222 rotates, and the first control valve 223 is arranged between the air outlet end of the branch circuit 221 and the air inlet end of the second drive component 2222.

[0094] It can be understood that the compressed air output by the air source 1 passes through the main air path 21 and the branch air path 221 in sequence and then enters the second drive component 2222. The driving end of the second drive component 2222 uses the compressed air to perform rotational motion. Therefore, when the drive system is applied to a vehicle, the second drive component 2222 can be used to drive the load 3 to perform linear motion, rotational motion, etc., thereby meeting the movement requirements of the load 3 of the vehicle.

[0095] It should be noted that the second driving component 2222 is used to utilize compressed air to make its driving end perform rotational motion. The specific type of the second driving component 2222 can be set according to actual needs and is not limited to this.

[0096] The second driving component 2222 can drive the load 3 to perform rotational motion, and can also drive the load 3 to perform linear motion, swinging motion, etc. with the help of a transmission mechanism, and there is no limitation to this.

[0097] like Figure 5 and Figure 6As shown, in some embodiments, the second driving assembly 2222 includes a second linear cylinder 22221 and a third linear cylinder 22222, and the first control valve 223 is a three-position five-way valve;

[0098] The rodless chamber ventilation end of the second linear cylinder 22221 and the rod chamber ventilation end of the third linear cylinder 22222 are respectively connected to the first end of the first control valve 223, and the third end of the first control valve 223 is connected to the outlet end of the branch air path 221, wherein the first end of the first control valve 223 is connected to the second end of the first control valve 223, or the first end of the first control valve 223 is connected to the third end of the first control valve 223;

[0099] And / or the rod chamber ventilation end of the second linear cylinder 22221 and the rodless chamber ventilation end of the third linear cylinder 22222 are respectively connected to the fourth end of the first control valve 223, and the third end of the first control valve 223 is connected to the outlet end of the branch air path 221, wherein the fourth end of the first control valve 223 is connected to the third end of the first control valve 223, or the fourth end of the first control valve 223 is connected to the fifth end of the first control valve 223.

[0100] It can be understood that, since the first control valve 223 is a three-position five-way valve, the first control valve 223 has five ports, namely the first end, the second end, the third end, the fourth end and the fifth end. When the first end of the first control valve 223 is connected to the second end of the first control valve 223, since the rodless chamber ventilation end of the second linear cylinder 22221 and the rod chamber ventilation end of the third linear cylinder 22222 are respectively connected to the first end of the first control valve 223, the rodless chamber of the second linear cylinder 22221 and the rod chamber of the third linear cylinder 22222 can be exhausted by the first control valve 223, so that the piston rod of the second linear cylinder 22221 can be retracted, and at the same time, the third linear cylinder 22222 can be retracted. The piston rod of the cylinder 22222 can extend; when the first end of the first control valve 223 is connected to the third end of the first control valve 223, since the rodless chamber ventilation end of the second linear cylinder 22221 and the rod chamber ventilation end of the third linear cylinder 22222 are respectively connected to the first end of the first control valve 223, the third end of the first control valve 223 is connected to the outlet end of the branch air path 221, so that the compressed air in the branch air path 221 can enter the rodless chamber of the second linear cylinder 22221 and the rod chamber of the third linear cylinder 22222, thereby driving the piston rod of the second linear cylinder 22221 to extend, and at the same time making the piston rod of the third linear cylinder 22222 retract. Therefore, by controlling the first control valve 223, the second linear cylinder 22221 and the third linear cylinder 22222 can perform telescopic movements, and the telescopic movements of the second linear cylinder 22221 and the third linear cylinder 22222 are opposite.

[0101] When the fourth end of the first control valve 223 is connected to the third end of the first control valve 223, since the rod chamber ventilation end of the second linear cylinder 22221 and the rodless chamber ventilation end of the third linear cylinder 22222 are respectively connected to the fourth end of the first control valve 223, the third end of the first control valve 223 is connected to the outlet end of the branch air path 221, so that the compressed air in the branch air path 221 can enter the rod chamber of the second linear cylinder 22221 and the rodless chamber of the third linear cylinder 22222, thereby driving the piston rod of the second linear cylinder 22221 to retract, and at the same time driving the third linear cylinder 2222 2 extends; when the fourth end of the first control valve 223 is connected to the fifth end of the first control valve 223, since the rod chamber ventilation end of the second linear cylinder 22221 and the rodless chamber ventilation end of the third linear cylinder 22222 are respectively connected to the fourth end of the first control valve 223, the rod chamber of the second linear cylinder 22221 and the rodless chamber of the third linear cylinder 22222 can be exhausted by the first control valve 223, so that the piston rod of the second linear cylinder 22221 can extend, and the piston rod of the third linear cylinder 22222 can retract. Thus, by controlling the first control valve 223, the second linear cylinder 22221 and the third linear cylinder 22222 can perform telescopic movements, and the telescopic movements of the second linear cylinder 22221 and the third linear cylinder 22222 are opposite.

[0102] It should be noted that, when only the rodless chamber ventilation end of the second linear cylinder 22221 and the rod chamber ventilation end of the third linear cylinder 22222 are respectively connected to the first end of the first control valve 223, and the third end of the first control valve 223 is connected to the outlet end of the branch air path 221, the second linear cylinder 22221 can use compressed air to extend the piston rod, and the third linear cylinder 22222 can use compressed air to retract the piston rod, and the piston rod retraction action of the second linear cylinder 22221 and the piston rod extension action of the third linear cylinder 22222 can be driven by other means, such as: manpower, the deadweight of the load 3, the spring in the load 3, the inertia of the load 3, etc. Among them, the first control valve 223 can be regarded as a two-position three-way valve.

[0103] When only the rod chamber ventilation end of the second linear cylinder 22221 and the rodless chamber ventilation end of the third linear cylinder 22222 are respectively connected to the fourth end of the first control valve 223, and the third end of the first control valve 223 is connected to the outlet end of the branch air path 221, the second linear cylinder 22221 can use compressed air to retract the piston rod, and the third linear cylinder 22222 can use compressed air to extend the piston rod, and the piston rod extension action of the second linear cylinder 22221 and the piston rod retraction action of the third linear cylinder 22222 can be driven by other means, such as: manpower, the deadweight of the load 3, the spring in the load 3, the inertia of the load 3, etc. Among them, the first control valve 223 can be regarded as a two-position three-way valve.

[0104] At the same time, the rodless chamber ventilation end of the second linear cylinder 22221 and the rod chamber ventilation end of the third linear cylinder 22222 are respectively connected to the first end of the first control valve 223, and the third end of the first control valve 223 is connected to the air outlet end of the branch air path 221, and the rod chamber ventilation end of the second linear cylinder 22221 and the rodless chamber ventilation end of the third linear cylinder 22222 are respectively connected to the fourth end of the first control valve 223, and the third end of the first control valve 223 is connected to the air outlet end of the branch air path 221. At this time, the second linear cylinder 22221 and the third linear cylinder 22222 can use compressed air to respectively extend and retract the piston rod, and the extension and retraction actions of the second linear cylinder 22221 and the third linear cylinder 22222 are opposite.

[0105] Among them, when the first control valve 223 is in the first open state, the first end is connected to the third end, and the fourth end is connected to the fifth end. At this time, the compressed air in the branch air path 221 can enter the rodless chamber of the second linear cylinder 22221 and the rod chamber of the third linear cylinder 22222, and the rod chamber of the second linear cylinder 22221 and the rodless chamber of the third linear cylinder 22222 can be exhausted by the first control valve 223, so that the piston rod of the second linear cylinder 22221 is extended under the drive of the compressed air, and the piston rod of the third linear cylinder 22222 is retracted under the drive of the compressed air. When the first control valve 223 is in the second open state, the first end is connected to the second end, and the fourth end is connected to the third end. At this time, the rodless chamber of the second linear cylinder 22221 and the rod chamber of the third linear cylinder 22222 can be exhausted by the first control valve 223, and the compressed air in the branch air path 221 can enter the rod chamber of the second linear cylinder 22221 and the rodless chamber of the third linear cylinder 22222, so that the piston rod of the second linear cylinder 22221 is retracted under the drive of the compressed air, and the piston rod of the third linear cylinder 22222 is extended under the drive of the compressed air. Therefore, the first control valve 223 can realize the alternating extension and retraction of the piston rod of the second linear cylinder 22221 and the piston rod of the third linear cylinder 22222 when switching between the first open state and the second open state.

[0106] When the second linear cylinder 22221 and the third linear cylinder 22222 drive the load 3 to rotate, for example, when the load 3 is a disc, the piston rods of the second linear cylinder 22221 and the third linear cylinder 22222 are respectively connected to the two ends of the disc, and the piston rods of the second linear cylinder 22221 and the third linear cylinder 22222 are respectively located on both sides of the disc, thereby realizing the rotation of the disc under the alternating extension and contraction of the second linear cylinder 22221 and the third linear cylinder 22222. Among them, the connection between the piston rods of the second linear cylinder 22221 and the third linear cylinder 22222 and the disc and the connection between the cylinder barrels of the second linear cylinder 22221 and the third linear cylinder 22222 and the installation position are all hinged.

[0107] like Figure 7 and Figure 8 As shown, in some embodiments, the second driving assembly 2222 includes a rotary cylinder 22223, and the first control valve 223 is a three-position five-way valve;

[0108] The rod chamber ventilation end of the rotary cylinder 22223 is connected to the first end of the first control valve 223, and the third end of the first control valve 223 is connected to the outlet end of the branch gas path 221, wherein the first end of the first control valve 223 is connected to the second end of the first control valve 223, or the first end of the first control valve 223 is connected to the third end of the first control valve 223;

[0109] And / or the rodless chamber ventilation end of the rotary cylinder 22223 is connected to the fourth end of the first control valve 223, the third end of the first control valve 223 is connected to the outlet end of the branch air path 221, wherein the fourth end of the first control valve 223 is connected to the third end of the first control valve 223, or the fourth end of the first control valve 223 is connected to the fifth end of the first control valve 223.

[0110] It can be understood that, since the first control valve 223 is a three-position five-way valve, the first control valve 223 has five ports, namely the first end, the second end, the third end, the fourth end and the fifth end. When the first end of the first control valve 223 is connected to the second end of the first control valve 223, the rod chamber of the rotary cylinder 22223 can be exhausted by the first control valve 223 because the rod chamber of the rotary cylinder 22223 is connected to the first end of the first control valve 223, so that the rotary cylinder 22223 can be exhausted by the rod chamber of the rotary cylinder 22223, thereby The piston rod of the cylinder 22223 can rotate in the forward direction; when the first end of the first control valve 223 is connected to the third end of the first control valve 223, since the rod chamber ventilation end of the rotary cylinder 22223 is connected to the first end of the first control valve 223, and the third end of the first control valve 223 is connected to the outlet end of the branch air path 221, the compressed air in the branch air path 221 can enter the rod chamber of the rotary cylinder 22223, thereby driving the piston rod of the rotary cylinder 22223 to rotate in the reverse direction. Therefore, by controlling the first control valve 223, the rotary cylinder 22223 can rotate in both directions.

[0111] When the fourth end of the first control valve 223 is connected to the third end of the first control valve 223, since the rodless chamber ventilation end of the rotary cylinder 22223 is connected to the fourth end of the first control valve 223, the third end of the first control valve 223 is connected to the outlet end of the branch air path 221, so that the compressed air in the branch air path 221 can enter the rodless chamber of the rotary cylinder 22223, thereby driving the piston rod of the rotary cylinder 22223 to rotate forward; when the fourth end of the first control valve 223 is connected to the fifth end of the first control valve 223, since the rodless chamber ventilation end of the rotary cylinder 22223 is connected to the fourth end of the first control valve 223, the rodless chamber of the rotary cylinder 22223 can be exhausted by the first control valve 223, thereby allowing the piston rod of the rotary cylinder 22223 to rotate in the opposite direction.

[0112] It should be noted that, when only the rod chamber ventilation end of the rotary cylinder 22223 is connected to the first end of the first control valve 223, and the third end of the first control valve 223 is connected to the outlet end of the branch air path 221, the rotary cylinder 22223 can use compressed air to reversely rotate the piston rod, and the forward rotation of the piston rod of the rotary cylinder 22223 can be driven by other means, such as manpower, the deadweight of the load 3, the spring in the load 3, etc. Among them, the first control valve 223 can be regarded as a two-position three-way valve.

[0113] When only the rodless chamber ventilation end of the rotary cylinder 22223 is connected to the fourth end of the first control valve 223, and the third end of the first control valve 223 is connected to the outlet end of the branch air path 221, the rotary cylinder 22223 can use compressed air to rotate the piston rod in the forward direction, and the reverse rotation of the piston rod of the rotary cylinder 22223 can be driven by other means, such as manpower, the deadweight of the load 3, the spring in the load 3, etc. Among them, the first control valve 223 can be regarded as a two-position three-way valve.

[0114] At the same time, the rod chamber ventilation end of the rotary cylinder 22223 is connected to the first end of the first control valve 223, and the third end of the first control valve 223 is connected to the outlet end of the branch air path 221, and the rodless chamber ventilation end of the rotary cylinder 22223 is connected to the fourth end of the first control valve 223, and the third end of the first control valve 223 is connected to the outlet end of the branch air path 221. At this time, the rotary cylinder 22223 can use compressed air to perform forward or reverse rotation of the piston rod.

[0115] Among them, when the first control valve 223 is in the first open state, the first end is connected to the third end, and the fourth end is connected to the fifth end. At this time, the compressed air in the branch air circuit 221 can enter the rod chamber of the rotary cylinder 22223, and the rodless chamber of the rotary cylinder 22223 can be exhausted by the first control valve 223, so that the piston rod of the rotary cylinder 22223 rotates in the opposite direction under the drive of compressed air; when the first control valve 223 is in the second open state, the first end is connected to the second end, and the fourth end is connected to the third end. At this time, the rod chamber of the rotary cylinder 22223 can be exhausted by the first control valve 223, and the compressed air in the branch air circuit 221 can enter the rodless chamber of the rotary cylinder 22223, so that the piston rod of the rotary cylinder 22223 rotates forward under the drive of compressed air. Thus, when the first control valve 223 is switched between the first open state and the second open state, the bidirectional rotation of the piston rod of the rotary cylinder 22223 can be achieved.

[0116] like Fig. 9 and Fig.10As shown, in some embodiments, the second drive assembly 2222 includes a pneumatic motor 22224, and the first control valve 223 is a three-position five-way valve;

[0117] The first ventilation end of the pneumatic motor 22224 is connected to the first end of the first control valve 223, and the third end of the first control valve 223 is connected to the outlet end of the branch gas path 221, wherein the first end of the first control valve 223 is connected to the second end of the first control valve 223, or the first end of the first control valve 223 is connected to the third end of the first control valve 223;

[0118] And / or the second ventilation end of the pneumatic motor 22224 is connected to the fourth end of the first control valve 223, the third end of the first control valve 223 is connected to the outlet end of the branch air path 221, wherein the fourth end of the first control valve 223 is connected to the third end of the first control valve 223, or the fourth end of the first control valve 223 is connected to the fifth end of the first control valve 223.

[0119] It can be understood that since the first control valve 223 is a three-position five-way valve, the first control valve 223 has five ports, namely the first end, the second end, the third end, the fourth end and the fifth end. When the first end of the first control valve 223 is connected to the second end of the first control valve 223, since the first ventilation end of the pneumatic motor 22224 is connected to the first end of the first control valve 223, the first ventilation end of the pneumatic motor 22224 can use the first control valve 223 to exhaust air, thereby allowing the output shaft of the pneumatic motor 22224 to rotate forward; when the first end of the first control valve 223 is connected to the third end of the first control valve 223, since the first ventilation end of the pneumatic motor 22224 is connected to the first end of the first control valve 223, the third end of the first control valve 223 is connected to the outlet end of the branch air path 221, so that the compressed air in the branch air path 221 can enter the first ventilation end of the pneumatic motor 22224, thereby driving the output shaft of the pneumatic motor 22224 to rotate in the reverse direction. Therefore, by controlling the first control valve 223, the pneumatic motor 22224 can rotate bidirectionally.

[0120] When the fourth end of the first control valve 223 is connected to the third end of the first control valve 223, since the second ventilation end of the air motor 22224 is connected to the fourth end of the first control valve 223, and the third end of the first control valve 223 is connected to the outlet end of the branch air path 221, the compressed air in the branch air path 221 can enter the second ventilation end of the air motor 22224, thereby driving the output shaft of the air motor 22224 to rotate in the forward direction; when the fourth end of the first control valve 223 is connected to the fifth end of the first control valve 223, since the second ventilation end of the air motor 22224 is connected to the fourth end of the first control valve 223, the second ventilation end of the air motor 22224 can be exhausted by the first control valve 223, thereby enabling the output shaft of the air motor 22224 to rotate in the reverse direction. Thus, by controlling the first control valve 223, the air motor 22224 can rotate in both directions.

[0121] It should be noted that, when only the first ventilation end of the pneumatic motor 22224 is connected to the first end of the first control valve 223, and the third end of the first control valve 223 is connected to the outlet end of the branch air path 221, the pneumatic motor 22224 can use compressed air to reversely rotate the output shaft, and the forward rotation of the output shaft of the pneumatic motor 22224 can be driven by other means, such as: manpower, the deadweight of the load 3, the spring in the load 3, etc. Among them, the first control valve 223 can be regarded as a two-position three-way valve.

[0122] When only the second ventilation end of the pneumatic motor 22224 is connected to the fourth end of the first control valve 223, and the third end of the first control valve 223 is connected to the outlet end of the branch air path 221, the pneumatic motor 22224 can use compressed air to rotate the output shaft in the forward direction, and the output shaft of the pneumatic motor 22224 can be driven in the reverse direction by other means, such as manpower, the deadweight of the load 3, a spring in the load 3, etc. Among them, the first control valve 223 can be regarded as a two-position three-way valve.

[0123] At the same time, the first ventilation end of the pneumatic motor 22224 is connected to the first end of the first control valve 223, and the third end of the first control valve 223 is connected to the outlet end of the branch air path 221, and the second ventilation end of the pneumatic motor 22224 is connected to the fourth end of the first control valve 223, and the third end of the first control valve 223 is connected to the outlet end of the branch air path 221. At this time, the pneumatic motor 22224 can use compressed air to perform forward or reverse rotation of the output shaft.

[0124] When the first control valve 223 is in the first open state, the first end is connected to the third end, and the fourth end is connected to the fifth end. At this time, the compressed air in the branch air path 221 can enter the first ventilation end of the pneumatic motor 22224, and the second ventilation end of the pneumatic motor 22224 can be exhausted by the first control valve 223, so that the output shaft of the pneumatic motor 22224 rotates in the reverse direction under the drive of the compressed air; when the first control valve 223 is in the second open state, the first end is connected to the second end, and the fourth end is connected to the third end. At this time, the first ventilation end of the pneumatic motor 22224 can be exhausted by the first control valve 223, and the compressed air in the branch air path 221 can enter the second ventilation end of the pneumatic motor 22224, so that the output shaft of the pneumatic motor 22224 rotates forward under the drive of the compressed air. Therefore, the first control valve 223 can realize the bidirectional rotation of the piston rod of the pneumatic motor 22224 when switching between the first open state and the second open state.

[0125] like Fig.11 and Fig.12 As shown, in some embodiments, the first control valve 223 is a two-position three-way valve, the pneumatic assembly 222 includes an air spring 2223 and a second air pressure sensor 2224, the ventilation end of the air spring 2223 is connected to the first end of the first control valve 223, the third end of the first control valve 223 is connected to the outlet end of the branch air path 221, and the detection end of the second air pressure sensor 2224 is arranged in the air spring 2223;

[0126] The first end of the first control valve 223 is communicated with the second end of the first control valve 223 , or the first end of the first control valve 223 is communicated with the third end of the first control valve 223 .

[0127] It can be understood that, since the first control valve 223 is a two-position three-way valve, the first control valve 223 has three ports, namely, the first end, the second end and the third end. When the first end of the first control valve 223 is connected to the second end of the first control valve 223, since the ventilation end of the air spring 2223 is connected to the first end of the first control valve 223, the air spring 2223 can be exhausted by the first control valve 223; when the first end of the first control valve 223 is connected to the third end of the first control valve 223, since the ventilation end of the air spring 2223 is connected to the first end of the first control valve 223, the third end of the first control valve 223 is connected to the outlet end of the branch air path 221, so that the compressed air in the branch air path 221 can enter the air spring 2223. Therefore, by controlling the first control valve 223, the amount of air in the air spring 2223 can be adjusted.

[0128] Among them, since the detection end of the second air pressure sensor 2224 is set in the air spring 2223, the driving system can use the second air pressure sensor 2224 to detect the air pressure in the air spring 2223, and then when the air pressure in the air spring 2223 is lower than the set threshold or higher than the set threshold, the driving system can use the first control valve 223 to add compressed air to the air spring 2223 or exhaust air from the air spring 2223, so that the air pressure in the air spring 2223 is maintained at the set threshold, thereby ensuring the stable operation of the load 3.

[0129] It should be noted that the air spring 2223 is a spring made using the elasticity of air, and the specific type of the air spring 2223 can be set according to actual needs and is not limited to this.

[0130] The second air pressure sensor 2224 is used to detect the air pressure in the air spring 2223. The specific type of the second air pressure sensor 2224 can be set according to actual needs and is not limited to this.

[0131] When the first control valve 223 is in the first open state, the first end is connected to the third end, and at this time, the compressed air in the branch air path 221 can enter the air spring 2223, so that the elastic force of the air spring 2223 increases with the filling of compressed air; when the first control valve 223 is in the second open state, the first end is connected to the second end, and at this time, the air spring 2223 can be exhausted by the first control valve 223, so that the elastic force of the air spring 2223 decreases with the discharge of compressed air. Therefore, the first control valve 223 can realize the elastic force adjustment action of the air spring 2223 when switching between the first open state and the second open state.

[0132] like Figure 2 As shown, in some embodiments, the gas circuit module 2 also includes a first muffler 23 and / or a second muffler 24, the first muffler 23 is arranged at the second air outlet end of the main gas circuit 21, and the second muffler 24 is arranged at the air outlet end of the pneumatic component 222.

[0133] It can be understood that since the first muffler 23 is arranged at the second air outlet end of the main air circuit 21, the noise generated when the second air outlet end of the main air circuit 21 is exhausted is greatly reduced, thereby avoiding noise pollution caused by the use of the drive system, thereby improving the user experience; since the second muffler 24 is arranged at the air outlet end of the pneumatic component 222, the noise generated when the air outlet end of the pneumatic component 222 is exhausted is greatly reduced, thereby avoiding noise pollution caused by the use of the drive system, thereby improving the user experience.

[0134] It should be noted that both the first muffler 23 and the second muffler 24 are cylinder mufflers, and the specific types of the first muffler 23 and the second muffler 24 can be set according to actual needs, and there is no limitation on this.

[0135] When the second muffler 24 is provided, if the air outlet end of the pneumatic component 222 uses the first control valve 223 to exhaust air, the second muffler 24 can be provided on the second end and the fifth end of the first control valve 223 .

[0136] According to actual use needs, only the first muffler 23 can be set at the second air outlet end of the main air circuit 21, or only the second muffler 24 can be set at the air outlet end of the pneumatic component 222, or the first muffler 23 can be set at the second air outlet end of the main air circuit 21 and the second muffler 24 can be set at the air outlet end of the pneumatic component 222 at the same time, and there is no limitation on this.

[0137] The embodiment of the present disclosure further provides a vehicle, comprising a load 3 and a driving system as in the embodiment of the present disclosure, wherein a power output end of a pneumatic component 222 in the driving system is connected to a power input end of the load 3 .

[0138] It can be understood that since the air inlet end of the main air circuit 21 is connected to the air outlet end of the air source 1, the air inlet end of the branch air circuit 221 is connected to the first air outlet end of the main air circuit 21, and the air outlet end of the branch air circuit 221 is connected to the air inlet end of the pneumatic component 222, the compressed air output by the air source 1 can pass through the main air circuit 21 and the branch air circuit 221 in sequence and enter the pneumatic component 222, so that the pneumatic component 222 can use the compressed air to operate, and since the first control valve 223 is arranged between the air outlet end of the branch air circuit 221 and the air inlet end of the pneumatic component 222 and selectively opens the passage between the air outlet end of the branch air circuit 221 and the air inlet end of the pneumatic component 222, the drive system can use the first control valve 223 to control the operation of the pneumatic component 222, and then control the load 3 of the vehicle to meet the movement requirements of the load 3 of the vehicle.

[0139] Since the pneumatic component 222 utilizes compressed air to output kinetic energy, and the whole only involves the control of the first control valve 223, the overall design power of the drive system is relatively low. Therefore, even when the drive system is not used frequently, the whole has a relatively high overall efficiency. At the same time, since the drive system utilizes the air source 1 for centralized supply of compressed air, and the whole only involves power loss at the air source 1 and the first control valve 223, the overall energy consumption is greatly reduced. Moreover, the pneumatic component 222 only involves the main air circuit 21 and the branch air circuit 221 as well as the wiring harness for controlling the first control valve 223, which greatly reduces the overall wiring harness and control devices, thereby effectively reducing the occupied space of the drive system and reducing the use cost of the drive system.

[0140] Among them, since the pneumatic component 222 uses compressed air to output kinetic energy, the pneumatic component 222 has the characteristics of small dead zone of movement, no overload burning, strong temperature adaptability, easy maintenance, high integration, and light weight compared to the electric motor. This not only reduces the size and weight of the drive system, but also makes the drive system more reliable and safe, and has a lower cost of use.

[0141] Since the control of the pneumatic component 222 is relatively simple, not only the control power consumption of the drive system is greatly reduced, the control wiring harness is greatly reduced, which is beneficial to the improvement of the vehicle's EMC and EMI environment, thereby improving the control efficiency of the entire vehicle, but also it can greatly reduce the high-power drive circuit on the vehicle's BCM, thereby reducing the device cost and heat dissipation cost of the BCM, and at the same time facilitates the layout of the BCM.

[0142] It should be noted that the specific type of vehicle can be set according to actual needs and is not limited to this. For example, the vehicle can be an electric vehicle, a fuel vehicle, etc.

[0143] In some embodiments, at least one gas circuit module 2 of the driving system includes a first gas circuit module and a second gas circuit module, and the first gas circuit module and the second gas circuit module are respectively located on both sides of the vehicle.

[0144] It can be understood that since the first air circuit module and the second air circuit module are respectively located on both sides of the vehicle, not only can the loads 3 on both sides of the vehicle be moved by utilizing the first air circuit module and the second air circuit module to meet the usage requirements, but also the space occupied by the vehicle is reduced, while facilitating the vehicle's control over the first air circuit module and the second air circuit module.

[0145] It should be noted that the first air circuit module can be set on the left side of the vehicle, and the second air circuit module can be set on the right side of the vehicle. The first air circuit module can be used to drive the vehicle's main driver's seat 31, second row of seats 31, left door lock 32, left window 33, front and rear wipers 34, etc., and the second air circuit module can be used to drive the vehicle's passenger seat 31, third row of seats 31, right door lock 32, right window 33, tailgate 35, etc., without any restriction.

[0146] The first gas circuit module and the second gas circuit module are both gas circuit modules 2.

[0147] like Fig.13 As shown, in some embodiments, the load 3 includes at least one of a seat 31, a door lock 32, a window 33, a wiper 34 and a tailgate 35, wherein the power output end of the pneumatic component 222 is connected to the power input end of at least one of the seat 31, the door lock 32, the window 33, the wiper 34 and the tailgate 35.

[0148] The load 3 may include one of the seat 31 , the door lock 32 , the window 33 , the wiper 34 and the tailgate 35 , or may include multiple of the seat 31 , the door lock 32 , the window 33 , the wiper 34 and the tailgate 35 , without limitation.

[0149] like Fig.13 As shown, in some embodiments, the load 3 includes a seat 31, wherein the power output end of the first drive component 2221 of the drive system is connected to the power input end of the seat 31; and / or the power output end of the second drive component 2222 of the drive system is connected to the power input end of the seat 31.

[0150] It can be understood that, since the power output end of the first drive component 2221 is connected to the power input end of the seat 31 , the drive system can utilize the first drive component 2221 to drive the movement of the seat 31 , thereby meeting the movement requirements of the seat 31 .

[0151] Since the power output end of the second driving component 2222 is connected to the power input end of the seat 31 , the driving system can utilize the second driving component 2222 to drive the movement of the seat 31 , thereby meeting the movement requirements of the seat 31 .

[0152] It should be noted that, according to actual usage needs, only the power output end of the first drive component 2221 of the drive system can be connected to the power input end of the seat 31, or only the power output end of the second drive component 2222 of the drive system can be connected to the power input end of the seat 31, or the power output end of the first drive component 2221 of the drive system can be connected to the power input end of the seat 31, and the power output end of the second drive component 2222 of the drive system can be connected to the power input end of the seat 31 at the same time, and there is no restriction on this.

[0153] According to actual use needs, the seat 31 can move in a single direction, the seat 31 can also move in multiple directions, the seat 31 can move in a linear direction, and the seat 31 can also move in a rotational direction, and there is no limitation on this.

[0154] Among them, when the seat 31 needs to move in multiple directions, multiple branch units 22 should be set, and the multiple branch units 22 correspond to the multiple directions of movement of the seat 31 respectively. For example, when the seat 31 needs to move up and down, left and right, and front and back, three branch units 22 are set, and the pneumatic components 222 of the three branch units 22 drive the up and down movement, left and right movement, and front and back movement of the seat 31 respectively.

[0155] Both the first drive assembly 2221 and the second drive assembly 2222 can realize the linear motion and rotational motion of the seat 31. For example, when the first drive assembly 2221 drives the seat 31 to move linearly, the first drive assembly 2221 can directly adopt the first linear cylinder 22211 and other components; when the first drive assembly 2221 drives the seat 31 to move rotationally, the first drive assembly 2221 can adopt the first linear cylinder 22211 and other components and configure corresponding transmission mechanisms; when the second drive assembly 2222 drives the seat 31 to move linearly, the second drive assembly 2222 can adopt the second linear cylinder 22221 and the third linear cylinder 22222, the rotary cylinder 22223, the pneumatic motor 22224 and other components and configure corresponding transmission mechanisms; when the second drive assembly 2222 drives the seat 31 to move rotationally, the second drive assembly 2222 can directly adopt the second linear cylinder 22221 and the third linear cylinder 22222, the rotary cylinder 22223, the pneumatic motor 22224 and other components.

[0158] It can be understood that, since the power output end of the first drive component 2221 is connected to the power input end of the door lock 32 , the drive system can utilize the first drive component 2221 to drive the movement of the door lock 32 , thereby meeting the switching requirements of the door lock 32 .

[0159] Since the power output end of the second drive component 2222 is connected to the power input end of the door lock 32 , the drive system can utilize the second drive component 2222 to drive the movement of the door lock 32 , thereby meeting the opening and closing requirements of the door lock 32 .

[0160] It should be noted that, according to actual usage needs, only the power output end of the first drive component 2221 of the drive system can be connected to the power input end of the door lock 32, or only the power output end of the second drive component 2222 of the drive system can be connected to the power input end of the door lock 32, or the power output end of the first drive component 2221 of the drive system can be connected to the power input end of the door lock 32, and the power output end of the second drive component 2222 of the drive system can be connected to the power input end of the door lock 32 at the same time, and there is no restriction on this.

[0161] According to actual use needs, the internal components of the door lock 32 can move in a single direction or in multiple directions. The internal components of the door lock 32 can move in a linear direction or in a rotational direction, and there is no limitation on this.

[0162] When the internal components of the door lock 32 need to move in multiple directions, multiple branch units 22 should be provided, and the multiple branch units 22 correspond to the multiple directions of movement of the internal components of the door lock 32 respectively.

[0163] The first drive assembly 2221 and the second drive assembly 2222 can both realize the linear motion and rotational motion of the internal components of the door lock 32. For example, when the first drive assembly 2221 drives the internal components of the door lock 32 to move linearly, the first drive assembly 2221 can directly use the first linear cylinder 22211 and other components. When the first drive assembly 2221 drives the internal components of the door lock 32 to move rotationally, the first drive assembly 2221 can use the first linear cylinder 22211 and other components and configure a corresponding transmission mechanism; the second drive assembly 2221 When 222 drives the internal components of the door lock 32 to move linearly, the second driving component 2222 can use the second linear cylinder 22221 and the third linear cylinder 22222, the rotary cylinder 22223, the pneumatic motor 22224 and other components and configure corresponding transmission mechanisms.

[0171] The first driving assembly 2221 and the second driving assembly 2222 can both realize the linear motion and the rotational motion of the vehicle window 33. For example, when the first driving assembly 2221 drives the vehicle window 33 to move linearly, the first driving assembly 2221 can directly use the first linear cylinder 22211 and other components. When the first driving assembly 2221 drives the vehicle window 33 to move rotationally, the first driving assembly 2221 can use the first linear cylinder 22211 and other components and configure a corresponding transmission mechanism.

[0179] The first drive assembly 2221 and the second drive assembly 2222 can both realize the linear motion and the rotational motion of the wiper 34. For example, when the first drive assembly 2221 drives the wiper 34 to move linearly, the first drive assembly 2221 can directly use the first linear cylinder 22211 and other components. When the first drive assembly 2221 drives the wiper 34 to move rotationally, the first drive assembly 2221 can use the first linear cylinder 22211 and other components and configure a corresponding transmission mechanism.
