[0002] In the automotive door sector, a variety of innovative ideas have mushroomed and flourished, such as scissor doors, falcon-wing doors, and sliding doors. However, traditional door stoppers generally have a simple structural design, requiring manual opening and closing. Long-term use can lead to internal structural damage and abnormal noise, further affecting the user experience. These designs fail to meet the current requirements for electrification and high-quality automotive products.

[0003] With the increasing popularity of new energy vehicles, electric vehicles have already captured a significant share of the automotive market. Their low noise levels, environmental friendliness, and various high-tech features are attractive selling points. Among these, the high-tech automatic door opening and closing feature offers unparalleled practicality.

[0004] The existing electric opening system of automobile doors is also called automobile electric door, generally referred to as electric door. It is a combination of door opening driver, electric suction door lock, radar, ECU and other parts installed on the automobile door to electrically open the automobile door. The door can be opened and closed without manual pushing and pulling. At present, the driver of automobile electric door is generally composed of a drive motor and a screw assembly. The drive motor drives the screw rod of the screw assembly to rotate, which then drives the slider on the screw rod to shift phase. The slider is then connected to the car body, or a push rod is added to the slider, which is then connected to the car body, thereby realizing the electric opening and closing of the automobile door. However, the above scheme has the disadvantages of large installation space, complex structure, large number of parts, inconvenient assembly, low applicability and high cost.

Those skilled in the art will understand the specific meanings of these terms in the present invention based on the specific circumstances.

[0044] Throughout this specification, reference to terms such as "one embodiment," "some embodiments," "illustrative embodiments," "examples," "specific examples," or "some examples" means that a specific feature, structure, material, or characteristic described in conjunction with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, illustrative uses of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0045] like Figures 1 to 9 As shown, the present invention discloses a vehicle side door driver device, comprising:

[0046] A drive motor 1 , wherein a worm 9 is provided on an output shaft of the drive motor 1 ;

[0047] The housing assembly 4 is mounted on the vehicle door body;

[0048] The transmission assembly 2 includes a worm gear 11, a threaded rod 6, a sliding guide device 7, and a drive connecting rod 3. The worm gear 11 drives the threaded rod 6 to rotate via a spline. The threaded rod 6 is threadedly connected to the sliding guide device 7. A guide portion 703 is provided on the sliding guide device 7. A sliding limit structure is formed between the guide portion 703 and the housing assembly 4. One end of the drive connecting rod 3 is connected to the sliding guide device 7, and the other end extends out of the housing assembly 4 and is connected to the vehicle body.

[0049] The worm 9 drives the worm wheel 11 to drive the threaded rod 6 to rotate. The rotation axis of the worm 9 is arranged perpendicular to the rotation axis of the threaded rod 6. During the rotation process, the threaded rod 6 drives the sliding guide device 7 to slide horizontally on the threaded rod 6. The driving connecting rod 3 moves integrally with the sliding guide device 7 to drive the car door to open or close relative to the car body.

[0050] The automobile side door drive device described in the present invention optimizes the transmission structure inside the drive, forms a worm gear transmission mechanism through the worm 9 provided by the drive motor 1 and the worm wheel 11 provided on the input end of the threaded rod 6, reduces the length direction of the drive, and utilizes the sliding limiting structure formed between the housing assembly 4 and the sliding guide device 7, such as a guide rail, a slider limiting structure, or a bump, a slide groove limiting structure, etc., to limit the circumferential movement of the sliding guide device 7 relative to the threaded rod 6. A screw transmission mechanism is formed between the sliding guide device 7 and the threaded rod 6, simplifies the transmission component, and further reduces the size of the drive. When in use, the drive motor 1 drives the worm 9 to drive the worm wheel 11 to rotate, and the worm wheel 11 drives the threaded rod 6 to rotate synchronously through the spline connection. The threaded rod 6 and the sliding guide device 7 are connected by a threaded connection to form a screw transmission mechanism. The threaded rod 6 converts the rotational motion into the linear motion of the sliding guide device 7 and generates an axial force. The axial force acts on the driving link 3 at the same time to make it move linearly synchronously. The driving link 3 applies the axial force to the connecting bracket 14 that is connected to the car body through linear motion. The connecting bracket 14 is arranged at the end of the driving link 3 extending out of the shell assembly 4. At this time, the car body generates a reaction force and acts on the car door along the drive. Since the reaction force does not pass through the rotation center of the car door body, there is a force arm between the reaction force and the rotation center of the car door body, so a rotational torque is generated to achieve the function of driving the car door body to automatically open or close.

[0051] Compared with the transmission structure in the prior art that realizes the relative sliding of the push rod through a screw, a guide rod, and a push rod, the automobile side door drive device described in the present invention has a simpler transmission structure, is more convenient to assemble, has higher space utilization, greatly reduces the size of the drive, improves installation efficiency, is lower in cost, and has stronger applicability.

[0052] As a preferred example of the present invention, the sliding guide device 7 includes a slider body 701 , the threaded rod 6 passes through the slider body 701 and is threadedly connected thereto, and a guide portion 703 is provided in at least two directions of the slider body 701 .

[0053] This arrangement further ensures the stability and reliability of the sliding movement of the sliding guide device 7 relative to the threaded rod 6 when the threaded rod 6 rotates, ensuring the reliable use of the automobile side door opening drive device described in the present invention.

[0054] As a preferred example of the present invention, the guide portion 703 includes a first guide protrusion 7031 and a second guide protrusion 7032. The first guide protrusion 7031 is provided at the upper end of the slider body 701, and forms a sliding guide limit structure with the upper inner wall of the housing assembly 4. The second guide protrusion 7032 is provided at the lower end of the slider body 701, and forms a sliding guide limit structure with the lower inner wall of the housing assembly 4. Specifically, the first guide protrusion 7031 includes two support leg limit plates, and the two support leg limit plates are bent and arranged toward opposite sides (front and back directions) of the sliding direction of the sliding guide device 7. The second guide protrusion 7032 includes at least two ribs, and the two ribs are also arranged toward opposite sides (front and back directions) of the sliding direction of the sliding guide device 7.

[0055] This setting has a simple structure and is easy to process and manufacture. It also further improves the stability and smoothness of the screw sliding transmission of the sliding guide device 7 relative to the housing assembly 4, avoids position deviation of the driving connecting rod 3 during movement, and causes failure of opening and closing of the automobile door body, further improving the reliability of the use of the automobile side door opening drive device described in the present invention.

[0056] As a preferred embodiment of the present invention, the sliding guide device 7 further includes a first connecting plate 702, which is disposed above the slider body 701. The first connecting plate 702 is plugged into the drive link 3 via a ball-and-socket connector 302 and a ball-and-socket fixing post 704. As an example of the present invention, the drive link 3 includes a guide rod body 301, with a ball-and-socket connector 302 disposed at the end of the guide rod body 301. Correspondingly, a ball-and-socket fixing post 704 is fixed to the first connecting plate 702, with the ball head of the ball-and-socket fixing post 704 inserted into the ball-and-socket connector 302 for connection. This arrangement connects the sliding guide device 7 to the drive link 3 via a ball-and-socket connection structure, preventing the torsional force generated by the relative sliding of the sliding guide device 7 during the rotational movement of the threaded rod 6 from being applied to the drive link 3, ensuring that the drive link 3 can slide stably and smoothly horizontally relative to the housing assembly 4. Furthermore, the rotary bearing disposed at the end of the threaded rod 6 away from the worm gear 11 can be eliminated, thereby further reducing accessories, lowering production costs, and improving assembly efficiency. Alternatively, the ball and socket fixing column 704 may also be provided at the end of the guide rod body 301 , and the ball and socket connector 302 may be fixed on the first connecting plate 702 .

[0057] As a preferred embodiment of the present invention, the first guide protrusion 7031 is provided on the upper surface of the first connecting plate 702. The first guide protrusion 7031 includes two vertical support plates 70311. A foot stop plate 70312 is provided at each end of the two vertical support plates 70311 away from the first connecting plate 702. At least one horizontal support plate 70313 is provided between the two vertical support plates 70311. Specifically, the two vertical support plates 70311 are provided in parallel, with the plane where the vertical support plates 70311 are located being perpendicular to the upper surface of the first connecting plate 702. Two horizontal support plates 70313 are provided, and the two horizontal support plates 70313 are provided near the middle of the vertical support plates 70311. The plane where the horizontal support plates 70313 are located is parallel to the plane where the foot stop plate 70312 is located.

[0058] This arrangement defines a structure and assembly structure of a first guide protrusion, which has a simple structure and a stable connection, and further improves the smoothness and reliability of the sliding guide device 7 in driving the driving connecting rod 3 to slide horizontally when the threaded rod 6 rotates.

[0059] As a preferred example of the present invention, a built-in damping device 10 is provided at the end of the worm gear 11 provided on the threaded rod 6 , and the built-in damping device 10 is used to achieve self-locking of the threaded rod 6 when the drive motor 1 loses power.

[0060] This arrangement enables the drive motor 1 to lose power accidentally during the opening and closing process of the automobile door, and the drive-side transmission structure of the worm 9 and worm wheel 11 can have a self-locking function to prevent the threaded rod 6 from rotating, and the built-in damping device 10 can further prevent the threaded rod 6 from rotating, thereby ensuring that even if the drive motor 1 loses power, the drive connecting rod 3 will not retract automatically, and the automobile door body can hover at any position to avoid the occurrence of safety accidents.

[0061] As a preferred example of the present invention, the built-in damping device 10 includes a damper housing 1001 and a damper connecting cover 1002, and an accommodating cavity 1006 is formed between the damper housing 1001 and the damper connecting cover 1002. A pressure plate friction plate assembly 1003 and a wave spring assembly 1004 are sequentially arranged in the accommodating cavity 1006. A healthy tooth connecting portion 1005 is provided on the side of the damper housing 1001 away from the damper connecting cover 1002, and the healthy tooth connecting portion 1005 is spline-connected to the worm gear 11. As an example of the present invention, the damper housing 1001 and the damper connection cover 1002 are detachably connected via a claw connection portion 1007 and a slot connection portion 1008. A plurality of the claw connection portions 1007 and the slot connection portions 1008 are provided correspondingly, and the claw connection portion 1007 can be provided on either the damper housing 1001 or the damper connection cover 1002. This arrangement requires the threaded rod 6 to overcome the static pressure generated by the pressure plate friction plate assembly 1003 and the wave spring assembly 1004 within the damper housing 1001 and the damper connection cover 1002 during rotation, further increasing the torque at the output end of the threaded rod 6. At the same time, the pressure plate friction plate assembly 1003 is assembled into one piece, thereby improving the ease of assembly and reliability of the built-in damping device 10.

[0062] As a preferred example of the present invention, the shell assembly 4 includes a first connecting shell 401 and a second connecting shell 402. The first connecting shell 401 is used to cover the connecting end of the drive motor 1 and the threaded rod 6. The second connecting shell 402 is used to cover the output end of the threaded rod 6 and the sliding guide device 7 and the driving connecting rod 3. The first connecting shell 401 and the second connecting shell 402 are detachably connected. A connecting cover 5 is provided on the side of the first connecting shell 401 away from the second connecting shell 402. An avoidance opening 12 is provided on the connecting cover 5. The end of the driving connecting rod 3 away from the sliding guide device 7 slides out from the avoidance opening 12.

[0063] As an example of the present application, the housing assembly 4 is divided into three parts: a detachable connecting cover 5, a first connecting shell 401, and a second connecting shell 402, so as to meet the assembly requirements of the transmission assembly 2 formed by the worm 9, the worm wheel 11, the threaded rod 6, the sliding guide device 7, and the built-in damping device 10 of the driving connecting rod 3. Preferably, the rotation axis of the worm 9 is arranged perpendicular to the rotation axis of the threaded rod 6. At the same time, when the built-in damping device 10 needs to be adjusted, it is only necessary to remove the connecting cover 5 to expose the built-in damping device 10, which is convenient and quick to adjust.

[0064] As a preferred embodiment of the present invention, a dustproof device 13 is provided on the avoidance opening 12. Preferably, the dustproof device 13 is a dustproof brush. This arrangement prevents dust from entering the drive mechanism through the avoidance opening 12 and generating abnormal noise.

[0065] The vehicle side door actuator device described in the present invention can upgrade the vehicle door bodies of existing models without changing the installation method of the existing vehicle door body limiter or destroying the existing structure within the vehicle door body, thereby improving vehicle quality and meeting customers' high-level usage requirements. Vehicles using the vehicle side door actuator device described in the present invention can achieve automatic and manual door opening and closing on flat slopes, uphill slopes, side slopes, and other conditions, and can maintain a full-angle hovering effect. At the same time, the present invention also designs a dustproof device 13 at the avoidance opening 12 on the connecting cover 5 to prevent dust from entering the drive mechanism and generating abnormal noise.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
