[0041] like Figures 1-3 As shown, in this embodiment, the electric side-opening door actuator includes a housing 1, a ball joint assembly 2, a motor 3, a transmission assembly 4, and a connecting rod 5. The ball joint assembly 2 is rotatably disposed within the housing 1, the motor 3 is disposed within the housing 1, and the transmission assembly 4 includes a double gear 41, a first gear 42, and a second gear 43. The double gear 41 is rotatably disposed within the housing 1 and meshes with the output end of the motor 3. The first gear 42 is rotatably disposed within the output end of the motor 3 and meshes with the double gear 41. The second gear 43 is fixedly sleeved on the ball joint assembly 2 and meshes with the first gear 42. The connecting rod 5 rotatably passes through the ball joint assembly 2 and connects to the door. The connecting rod 5 can move axially relative to the housing 1 to open or close the door.

[0042] A motor 3 is housed inside the housing 1. A first gear 42 is fitted onto the output end of the motor 3. The first gear 42 is either a spur gear or a helical gear. A double gear 41 and a second gear 43 are also correspondingly configured as spur gears or helical gears, ensuring meshing with the first gear 42. The first gear 42 can rotate relative to the output end of the motor 3. The double gear 41 is rotatably mounted inside the housing 1, and its meshing with the output end of the motor 3 and the first gear 42 provides a transmission connection. A connecting rod 5 passes through the housing 1, and a ball-and-socket assembly 2 is mounted on the connecting rod 5. The ball-and-socket assembly 2 is in a transmission connection with the connecting rod 5, and a second gear 43 is fixedly nested on the ball-and-socket assembly 2. Specifically, the outer ring of the ball-and-socket assembly 2 is fixedly connected to the second gear 43, and the inner ring of the ball-and-socket assembly 2 is connected to the connecting rod 5 to form a transmission pair.

[0043] The working process of this electric side-opening door actuator is as follows: First, the motor 3 starts. Under the driving action of the motor 3, the output end of the motor 3 drives the double gear 41 to rotate. The double gear 41 drives the first gear 42 to rotate relative to the output end of the motor 3. The first gear 42 drives the second gear 43 to rotate. At the same time, the ball joint assembly 2 rotates synchronously with the second gear 43. The rotation of the ball joint assembly 2 drives the connecting rod 5 to move axially and extend relative to the housing 1, so that the door can open or close relative to the vehicle body. By converting the rotation of the motor 3 into the extension and retraction of the connecting rod 5, the transmission assembly 4 can play the role of speed reduction and torque increase, resulting in high transmission efficiency and improved reliability of the electric side-opening door opening and closing. It has fewer parts, is easy to assemble, and facilitates later maintenance.

[0044] Furthermore, referring to Figures 2-3The transmission assembly 4 also includes an output gear 44, which is fixedly sleeved on the output end of the motor 3 and meshes with a double gear 41. The output gear 44 is configured as a spur gear or a helical gear. The double gear 41 includes a first meshing part 411 and a second meshing part 412. The first meshing part 411 meshes with the output gear 44, and the second meshing part 412 meshes with the first gear 42. The output gear 44 is a tooth of the motor 3. When the motor 3 starts, the output end of the motor 3 and the output gear 44 rotate synchronously. The output gear 44 drives the first meshing part 411 to rotate. At the same time, the second meshing part 412 drives the first gear 42 to rotate. The first gear 42 drives the second gear 43 to rotate. Simultaneously, the ball joint assembly 2 rotates synchronously with the second gear 43. The rotation of the ball joint assembly 2 drives the connecting rod 5 to move axially and extend relative to the housing 1, so that the door can open or close relative to the vehicle body.

[0045] Furthermore, continue to refer to Figures 2-3 The ball socket assembly 2 includes a ball socket 21 and a ball socket sleeve 22. The ball socket 21 is wound around the connecting rod 5 and can be drivenly connected to the connecting rod 5. The ball socket sleeve 22 is fixedly sleeved on the ball socket 21 and rotatably connected to the housing 1. The outer ring of the ball socket sleeve 22 is fixedly connected to the second gear 43. The ball socket sleeve 22 is formed by two sleeves being spliced ​​together. The ball socket sleeve 22 has a symmetrical structure, which facilitates installation. The ball socket assembly 2 also includes a pin 24. The ball socket sleeve 22 has a connecting hole, and the ball socket 21 has a fixing hole. The pin 24 is fixedly inserted into the connecting hole and the fixing hole to fix the ball socket sleeve 22 and the ball socket 21 relatively, ensuring that there is no relative movement between the ball socket 21 and the ball socket sleeve 22. The fixing hole is an elongated structure. After one end of the pin 24 is fixed to the connecting hole, the other end of the pin 24 can be easily fixed and connected through the elongated fixing hole, avoiding the inability to insert the pin 24 due to misalignment between the fixing hole and the connecting hole, thus ensuring high adaptability.

[0046] Furthermore, continue to refer to Figures 2-3 The ball socket assembly 2 also includes a bearing 23, which is sleeved on the ball socket sleeve 22. The inner ring of the bearing 23 is fixedly connected to the ball socket sleeve 22, and the outer ring of the bearing 23 is fixedly connected to the housing 1. In this embodiment, there are two bearings 23, located on both sides of the ball socket sleeve 22 along the axial direction of the connecting rod 5. The ball socket sleeve 22 can rotate within the housing 1 via the bearings 23.

[0047] Furthermore, continue to refer to Figures 2-3The ball socket 21 also has a connecting hole with an internal thread on its wall and an external thread on the outer circumference of the connecting rod 5. The ball socket 21 and the connecting rod 5 are threaded together. The connecting hole inside the ball socket 21 has a threaded structure that mates with the connecting rod 5. That is, the ball socket 21 and the connecting rod 5 are rotatably connected to form a transmission pair, so that the ball socket assembly 2 rotates to drive the connecting rod 5 to move axially relative to the housing 1, allowing the door to open or close relative to the vehicle body.

[0048] Furthermore, continue to refer to Figures 2-3 The electric side-opening door actuator also includes a seal 6. The housing 1 includes a first outer shell 11 and a second outer shell 12. The first outer shell 11 is installed in the opening of the second outer shell 12, and the seal 6 is clamped at the joint between the first outer shell 11 and the second outer shell 12. The seal 6 is a sealing ring, which ensures good sealing after the first outer shell 11 and the second outer shell 12 are assembled into the housing 1 by bolts, ensuring that the lubricating oil inside the housing 1 is not easily leaked. At the same time, it prevents external dust from entering the housing 1 and affecting the transmission efficiency of the transmission assembly 4. Driven by the motor 3, the transmission assembly 4, and the ball joint assembly 2, the connecting rod 5 can be axially displaced relative to the housing 1 to open or close the door.

[0049] Furthermore, continue to refer to Figures 2-3 The electric side-opening door actuator also includes a pull ring 7 and a stop 8. The pull ring 7 and the stop 8 are respectively disposed at both ends of the connecting rod 5. The pull ring 7 is fixedly connected to the door, and the stop 8 is used to limit the axial displacement of the connecting rod 5 relative to the housing 1. The connecting rod 5 is connected to the door through the pull ring 7. The axial displacement of the connecting rod 5 relative to the housing 1 extends or retracts to open or close the door. The stop 8 is used to limit the maximum opening and closing angle of the door.

[0050] This embodiment also provides a side-opening car door, including a door body and an electric side-opening door actuator, which is mounted on the door body. A double gear 41 is rotatably mounted on the housing 1 and meshes with the output end of the motor 3. A first gear 42 is rotatably mounted on the output end of the motor 3 and meshes with the double gear 41. A second gear 43 is fixedly sleeved on the ball joint assembly 2 and meshes with the first gear 42. A connecting rod 5 rotatably passes through the ball joint assembly 2 and is connected to the door body. The connecting rod 5 can move axially relative to the housing 1 to open or close the door body. By converting the rotation of the motor 3 into the extension and retraction of the connecting rod 5, the transmission assembly 4 can reduce speed and increase torque, resulting in high transmission efficiency and improved reliability of the electric side-opening door.

[0051] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
