Description

Technical Field

[0001] This utility model relates to the field of drive motor technology, specifically to a drive motor for a car side sliding door. Background Technology

[0002] Automotive sliding doors, especially electric sliding doors used in MPVs, minivans, and high-end SUVs, greatly enhance the convenience and luxury of vehicle use with their automatic opening and closing function. The core component of this function is the car sliding door drive motor, which receives instructions from the electronic control unit to drive the transmission mechanism (such as a steel cable or screw), thereby realizing the automatic opening and closing of the door. Currently, the drive motor is usually integrated into the interior space of the door cavity or the body frame. When it malfunctions, in order to repair or replace the faulty motor, the repair personnel usually need to perform a cumbersome disassembly process: first, the entire interior panel of the sliding door and even the door assembly need to be removed from the vehicle to expose the internal drive assembly; only then can the drive motor be disassembled. However, the following drawbacks still exist: simple motor failures involve a large amount of disassembly and assembly time, resulting in high final repair costs; in emergency situations where the motor fails and cannot be repaired immediately, the door system often gets stuck in a certain position, making it difficult to quickly switch to a reliable manual mode, causing the doors to be unable to open and close normally, which seriously affects the use of the vehicle. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a drive motor for a car side sliding door, which solves the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A sliding door drive motor for automobiles includes: a main housing; a secondary housing fixedly mounted on one side of the main housing, and a transmission chamber 1 and a transmission chamber 2 respectively disposed within the secondary housing; a transmission assembly being assembled inside both transmission chamber 1 and transmission chamber 2; a mounting assembly being assembled inside the main housing; a motor fixedly mounted on one side of the mounting assembly; the output end of the motor passing through the mounting assembly and connected to a connecting assembly; the motor being connected to the transmission assembly via the connecting assembly; and a rotating component rotatably mounted on one side of the secondary housing and connected to the transmission assembly; the mounting assembly includes a mounting base and a loading plate; the connecting assembly includes a drive shaft, and... The driven shaft has a locking seat fixedly installed inside the main housing. The locking seat holds a loading plate. The motor is installed on one side of the loading plate. The output end of the motor is connected to the drive shaft, which has a connection port one. The driven shaft is rotatably installed between the main housing and the transmission chamber two. The driven shaft has a connecting block, which has a connection port two. The driven shaft is mutually locked with the drive shaft through the connecting block, the connection port two, the connection port one, and the connection port two. The rotating component includes a rotating cap and a drive block. A rotating cap that is connected to the transmission assembly is rotatably installed on one side of the sub-housing. The drive block is fixedly installed inside the rotating cap.

[0005] This utility model provides a drive motor for a sliding door in an automobile. Compared with the prior art, it has the following advantages: 1. The combination of slots, loading plates and fastening knobs enables modular installation of the motor. When the motor needs to be repaired or replaced, there is no need to disassemble the entire drive assembly. The motor module can be pulled out as a whole simply by loosening two knobs, which greatly shortens the maintenance time and labor costs. Meanwhile, the design of the connecting components constitutes a floating coupling; its technical advantages are: during insertion and installation, the connecting block can automatically align and embed itself into the connection port, compensating for minor installation coaxiality deviations and ensuring smooth power transmission; when the motor is disassembled, the power connection is automatically disconnected; during installation, the connection is automatically restored. This process requires no additional adjustments, achieving a plug-and-play effect; 2. In case of motor failure, power outage, or control system malfunction, the rotating cap and drive block provide a purely mechanical emergency operation interface; by directly rotating the rotating cap with a tool, power is transmitted directly to the worm gear through the connecting shaft, bypassing the faulty motor and electrical system, ensuring that the door can still be manually opened and closed in an emergency, and guaranteeing the safety of passengers entering and exiting.

[0009] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0010] As an embodiment of this utility model, to solve the technical problems in the background art, the following automobile side sliding door drive motor is provided. Combined with... Figures 1-5As shown, it includes: a main housing 100, a secondary housing 200 fixedly mounted on one side of the main housing 100, and a transmission chamber 1 201 and a transmission chamber 202 respectively disposed inside the secondary housing 200. A transmission assembly 600 is assembled inside both transmission chamber 1 201 and transmission chamber 202. An installation assembly 400 is assembled inside the main housing 100. A motor 300 is fixedly mounted on one side of the installation assembly 400. The output end of the motor 300 passes through the installation assembly 400 and is connected to a connecting assembly 800. The motor 300 is connected to the transmission assembly 600 via the connecting assembly 800. A rotating component 700 connected to the transmission assembly 600 is rotatably mounted on one side of the secondary housing 200. The installation assembly 400 includes a locking seat 401 and a loading plate 403. The connecting assembly 800 includes a drive shaft 801 and a driven shaft 803. The main housing 100 has a fixed mounting bracket 401 inside, and a loading plate 403 is mounted inside the mounting bracket 401. The motor 300 is mounted on one side of the loading plate 403. The output end of the motor 300 is connected to the drive shaft 801, and the drive shaft 801 is provided with a first connection port 802. The driven shaft 803 is rotatably mounted between the main housing 100 and the transmission chamber 202. The driven shaft 803 is provided with a connecting block 804, and the connecting block 804 is provided with a second connection port 805. The driven shaft 803 is connected to the drive shaft 801 through the connecting block 804, the second connection port 805, the first connection port 802, and the drive shaft 801. The rotating component 700 includes a rotating cap 701 and a drive block 702. The rotating cap 701, which is connected to the transmission assembly 600, is rotatably mounted on one side of the sub-housing 200, and the drive block 702 is fixedly mounted inside the rotating cap 701.

[0011] In the above scheme: The main housing 100 and the secondary housing 200 are fixedly connected to form the main frame of the equipment. The interior of the secondary housing 200 is divided into transmission chamber one 201 and transmission chamber two 202 to accommodate the transmission mechanism. The motor 300 serves as the power source and is designed based on the YC-021 side sliding door motor. Its output shaft is connected to the transmission assembly 600 through the connecting component 800. The specific path is as follows: motor 300, drive shaft 801, driven shaft 803, worm 603, worm wheel 601, transmission gear sleeve 602. Finally, the power is output from the transmission gear sleeve 602 to drive the side sliding door to move.

[0012] The mounting component 400 has a snap-fit ​​seat 401 fixed inside the main housing 100. The loading plate 403 can be inserted into its slot 402 and secured. The motor 300 is fixed on the loading plate 403. The drive shaft 801 and driven shaft 803 of the connecting component 800 achieve power transmission through the engagement of the first connecting port 802, the connecting block 804 and the second connecting port 805. This design allows the motor and its drive shaft 801 to automatically separate from the transmission system simply by pulling out the loading plate 403 during disassembly.

[0013] The rotating cap 701 of the rotating component 700 has a non-circular drive block 702 inside. When the motor fails, a special tool or a manual wrench can be inserted and rotated to directly drive the worm gear 603, thereby realizing the manual opening and closing of the side sliding door.

[0014] In this embodiment, the transmission assembly 600 includes a worm gear 601, a transmission sleeve 602, and a worm 603. The worm gear 601 is rotatably mounted inside the first transmission chamber 201, and the transmission sleeve 602 is fixedly mounted on the front side of the worm gear 601. The worm 603 is rotatably mounted inside the second transmission chamber 202.

[0015] Inside transmission chamber 202, worm 603 is coaxially connected to driven shaft 803. Inside transmission chamber 1 201, worm wheel 601 meshes with worm 603 to form a worm gear reduction mechanism. This mechanism has the characteristics of large transmission ratio and good self-locking, which can effectively reduce motor speed, increase output torque, and prevent the side sliding door from moving due to external force when stationary.

[0016] A transmission gear sleeve 602 is fixedly mounted on the front of the worm gear 601. The inner hole of the transmission gear sleeve 602 is usually designed with splines or specific tooth profiles for connecting with the input shaft of the door drive mechanism to ultimately transmit power to the side sliding door.

[0017] In this embodiment, a detachable cover plate 500 is fixedly installed on the front of the main housing 100, and the cover plate 500 is provided with an assembly hole 501 corresponding to the transmission gear sleeve 602.

[0018] The cover plate 500 is fixed to the front of the main housing 100 by screws. After removing the cover plate 500, the transmission chamber 201 is exposed, providing a channel for direct contact with the transmission sleeve 602 and the worm gear 601. This mounting hole 501 facilitates: lubrication and maintenance of the transmission components; direct observation of gear meshing; and serves as a docking port for the output shaft and the transmission sleeve 602.

[0019] In this embodiment, the mounting base 401 is provided with a slot 402 for mounting the loading plate 403, and two sets of fastening knobs 404 are threadedly installed on the mounting base 401.

[0020] The shape of the slot 402 matches the outer contour of the loading plate 403, ensuring that it will not wobble after insertion and initial positioning. After the fastening knobs 404 on both sides are screwed in, their ends press tightly against the loading plate 403, generating huge friction force to firmly fix it in the card holder 401, resisting the vibration and torque when the motor is working. When disassembling, you only need to loosen these two knobs, which is extremely convenient.

[0021] In this embodiment, a bearing seat is fixedly installed on the other side of the loading plate 403, and the output shaft of the motor 300 passes through the bearing seat and is installed and connected to the drive shaft 801.

[0022] The bearing seat fixed to the loading plate 403 provides an additional support point for the output shaft of the motor 300. This design has two key effects: Increased rigidity: Reduces the deflection of the output shaft under stress, resulting in smoother operation and extended motor life; Ensure alignment: Ensure that the motor output shaft, drive shaft 801 and driven shaft 803 are on the same axis to ensure smooth power transmission and reduce abnormal wear and noise.

[0023] In this embodiment, the rotating component 700 further includes a connecting shaft 703. The connecting shaft 703 is rotatably mounted on one side of the sub-housing 200 via a bearing. The inner end of the connecting shaft 703 is connected to the end of the worm gear 603, and a rotating cap 701 is fixedly mounted on the outer end of the connecting shaft 703.

[0024] The connecting shaft 703 is mounted on the secondary housing 200 via bearings, ensuring smooth rotation and low resistance. Its inner end is fixed to the end of the worm 603 via splines or set screws, while the outer end is fixedly mounted with a rotating cap 701. Therefore, the torque generated by rotating the rotating cap 701 is directly transmitted to the worm 603 without loss through the connecting shaft 703, thereby driving the entire transmission system. The use of bearings ensures that manual operation is easy and effortless.

[0025] Working principle and usage process of this utility model: In use, the connecting wires on the motor 300 are matched and connected to the external controller. When the motor 300 is started, the motor 300 can drive the drive shaft 801 to rotate using its own output shaft. The drive shaft 801 can then rotate synchronously through the driven shaft 803, which is engaged by the connecting port 1 802, the connecting block 804, and the connecting port 2 805. At that time, the other end of the driven shaft 803 will synchronously drive the worm gear 603 to rotate. The worm gear 603 drives the worm wheel 601, causing the transmission gear sleeve 602 on the worm wheel 601 to rotate. The transmission gear sleeve 602 uses its internal tooth structure to drive the connecting shaft to rotate. When the motor malfunctions during operation and cannot be driven normally, personnel can manually adjust the motor structure without disassembling the cover plate 500. The operation is completed by personnel using tools or manually. The method is as follows: the motor 300 is a non-self-locking motor. Tools or fingers are inserted into the rotating cap 701 to apply force to the drive block 702, causing the rotating cap 701 to drive the worm gear 603 to rotate through the connecting shaft 703. The drive is achieved by manually rotating the worm gear 603, thus controlling the sliding door and facilitating personnel to perform inspection and maintenance. If the motor 300 needs to be disassembled for maintenance or replacement: personnel first disassemble the parts on the cover plate 500, and then rotate the fastening knob 404 to loosen the fastening between the loading plate 403 and the locking seat 401. Then, personnel can pull the loading plate 403 out of the locking seat 401, and the synchronous motor 300 can be taken out. During the removal, the drive shaft 801 is separated from the driven shaft 803 through the first connection port 802 and the second connection port 805. This allows for quick disassembly and separation of the motor 300.

[0026] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
