[0029] like Figures 1 to 10 As shown, the drive system of this disclosure may include components such as an electric actuator 100, a first steering component 200, and a second steering component 300.

[0030] In use, the drive system disclosed herein can fix the electric actuator 100, the first steering component 200, and the second steering component 300 to the vehicle body. A track is also provided on the vehicle body, and a sliding component is mounted on the track. When the electric actuator 100 is activated, it can drive the sliding component to slide along the track. When the sliding door is fixed to the sliding component, the electric actuator 100 can drive the sliding door to move.

[0031] Those skilled in the art should know that the fixing methods of the electric actuator 100, the first steering component 200, and the second steering component 300 can be implemented using existing technologies, and this disclosure will not elaborate on them one by one.

[0032] The electric actuator 100 of this disclosure is used to drive the movement of the first rope 400 and the second rope 500; in other words, the electric actuator 100 of this disclosure can drive the first rope 400 or the second rope 500 to retract. Furthermore, since the first rope 400 and the second rope 500 are fixed to the same component, when the first rope 400 retracts, the second rope 500 can be pulled out. Similarly, when the second rope 500 retracts, the first rope 400 can be pulled out.

[0033] One end of the first rope 400 passes through the first steering member 200 and is turned by the first steering member 200; and the other end of the second rope 500 passes through the second steering member 300 and is turned by the second steering member 300; thus, the first rope 400 and the second rope 500 of this disclosure can extend or retract in a predetermined direction.

[0034] The structure of the electric actuator 100 will be described below with reference to the accompanying drawings.

[0035] Specifically, the electric actuator 100 disclosed herein may include components such as a first housing 110, a second housing 120, an intermediate housing 130, and a motor 140.

[0036] The first housing 110 forms the base structure of the electric actuator 100 of this disclosure, thereby fixing the electric actuator 100 to the vehicle body. In a preferred embodiment, the first housing 110 may have components such as a first mounting hole 111, a second mounting hole 112, and a third mounting hole 113, in which case three mounting screws can pass through the first mounting hole 111, the second mounting hole 112, and the third mounting hole 113 respectively, and fix the first housing 110 to the vehicle body.

[0037] More preferably, the first mounting hole 111 and the second mounting hole 112 can be circular holes, and the third mounting hole 113 can be an elongated hole. Thus, the first mounting hole 111 and the second mounting hole 112 can achieve accurate positioning and fixation of the electric actuator 100 during installation. At this time, the elongated third mounting hole 113 can prevent problems such as misalignment of the machine body holes that make it difficult to install the electric actuator, facilitating the installation of the electric actuator 100 by workers on the production line.

[0038] In this disclosure, vibration damping components 114 are provided in the first mounting hole 111, the second mounting hole 112, and the third mounting hole 113. These vibration damping components 114 can be pads made of materials such as rubber. By providing these vibration damping components 114, the vibration and noise of the electric actuator 100 during operation can be effectively reduced, improving the user experience. Additionally, a bushing 115 can be provided in the vibration damping component 114. This bushing 115 can be made of metal and makes pressure contact with the vehicle body, thus fixing the electric actuator 100 to the vehicle body.

[0039] The intermediate housing 130 is fixed to the first housing 110, and the second housing 120 is fixed to the intermediate housing 130, so that the first housing 110 and the second housing 120 are located on both sides of the intermediate housing 130.

[0040] The motor 140 is fixed to the first housing 110. A magnetic ring 141 is installed on the output shaft of the motor 140, and a Hall element 142 is provided on the motor 140. The magnetic ring 141 is used to trigger the Hall element 142.

[0041] Therefore, in the drive system of this disclosure, the real-time position of the sliding door can be calculated by detecting the position of the motor 140. In other words, the position detection of the high-speed side motor 140 in the drive system of this disclosure has higher accuracy than the position detection of the low-speed side of the sliding door in the prior art.

[0042] In this disclosure, a worm gear portion 143 is provided on the output shaft of the motor 140, and a gear 144 is rotatably disposed within the first housing 110. The worm gear portion 143 meshes with the gear 144, thereby enabling the gear 144 to rotate when the motor 140 rotates. In a preferred embodiment, the worm gear portion 143 is a double-headed worm.

[0043] In this disclosure, gear 144 can be a helical gear, and gear 144 can also be replaced by a worm gear.

[0044] The gear 144 has a central hole in which a gear shaft is installed. The gear shaft is circumferentially connected to the gear 144, so that the gear 144 and the gear shaft can rotate synchronously.

[0045] In a preferred embodiment, gear 144 is drivenly connected to drum 150, which is located between intermediate housing 130 and second housing 120. Specifically, at least a portion of the gear shaft is provided with an external spline, and the center hole of drum 150 is provided with an internal spline. Thus, the gear shaft and drum 150 are connected by a spline engagement, allowing gear 144, gear shaft, and drum 150 to rotate synchronously.

[0046] In this disclosure, the other end of the first rope 400 is fixed to the drum 150, and a portion of the first rope 400 is wound around the drum 150; the other end of the second rope 500 is fixed to the drum 150, and the other end of the second rope 500 is wound around the drum 150, so that when the drum 150 rotates, the first rope 400 and the second rope 500 can move synchronously and in opposite directions.

[0047] In some embodiments, a cover plate is provided on the first housing 110, one end of the gear shaft can be rotatably supported on the cover plate, and the other end can be rotatably disposed on the second housing 120. In a preferred embodiment, the middle part of the gear shaft can be rotatably supported on the intermediate housing 130, thereby the gear shaft of the present disclosure has good axial and radial stability. In other words, the gear shaft of the present disclosure is not easily displaced in either the axial or radial direction.

[0048] The electric actuator 100 disclosed herein also includes components such as a first tensioning device 160 and a second tensioning device 170. The first tensioning device 160 is disposed between the intermediate housing 130 and the second housing 120, and is used to tension the first rope 400. The second tensioning device 170 is disposed between the intermediate housing 130 and the second housing 120, and is used to tension the second rope 500.

[0049] Therefore, the electric actuator disclosed herein has a high degree of integration and is easy for workers to install.

[0050] Specifically, the first tensioning device 160 and the second tensioning device 170 of this disclosure have the same structure / symmetrical structure, and the following description only uses the first tensioning device 160 as an example.

[0051] The intermediate housing 130 and the second housing 120 of this disclosure are both formed with guide structures. The first tensioning device 160 includes a support frame 161, a pulley 162 and a spring 163. The support frame 161 is slidably disposed on the intermediate housing 130 and the second housing 120 and can be guided by the guide structures of the intermediate housing 130 and the second housing 120.

[0052] The pulley 162 of this disclosure is rotatably mounted on the support frame 161, at which time the first rope 400 can be wound around the pulley 162 and tensioned by the first tensioning device 160.

[0053] One end of the spring 163 is supported on the support frame 161, and the other end of the spring 163 is supported on the second housing 120. The spring 163 is in a pre-compressed state, so that the support frame 161 has a tendency to move from the first position to the second position due to the elastic force applied by the spring 163.

[0054] The first tensioning device 160 disclosed herein also includes a limiting member 164 for limiting the support frame 161 to a first position. Specifically, a limiting hole is provided on the second housing 120, and the limiting member can be inserted into the limiting hole and can prevent the support frame 161 from moving to the second position, thereby limiting the support frame 161 to the first position.

[0055] At this time, since the first tensioning device 160 is in the first position, the first rope 400 has a relatively long extension length, which makes it convenient for the worker to fix the first rope 400 to the sliding member. After the worker completes the assembly and connection of the entire drive system, the limiting member 164 can be removed. At this time, the first tensioning device 160 can apply tension to the first rope 400, so that the drive system is in normal working condition.

[0056] Both the intermediate housing 130 and the second housing 120 of this disclosure are provided with elongated slots, which are arranged along the direction from the first position to the second position. In other words, the elongated slots are arranged along the movement direction of the support frame 161. Moreover, the pulley axle of the pulley 162 corresponds to the position of the elongated slot, thereby allowing a worker to drive the support frame 161 from the second position to the first position using tools such as screwdrivers. After the support frame 161 moves to the first position, the aforementioned limiting member 164 is inserted, and the limiting member 164 restricts the support frame 161 to the first position.

[0057] According to another aspect of this disclosure, a sliding door is provided, which includes the aforementioned drive system.

[0058] According to another aspect of this disclosure, a motor vehicle is provided, which includes the drive system described above, and / or includes the sliding door described above.
