Description

Technical Field

[0001] The utility model relates to a door driving device for an automobile. Background Art

[0002] With the development of my country's automobile industry, the types and functions of automobiles are becoming increasingly numerous and diverse. People have higher and higher requirements for automobile comfort, and the use of vehicles is increasingly tending towards intelligence and automation. For car doors, more humane opening and closing will improve passenger comfort.

[0003] The automatic opening and closing of car doors generally uses a drive device, which drives the pull rope to be retracted and released, and drives the car door to be opened and closed through the pull rope, thereby realizing the automatic operation of the car door. However, the traditional car door drive device will be affected by the brushes inside its motor body during operation. In actual use, there is a risk of electric sparks generated by the brushes during the rotation of the motor, so there is a certain safety hazard. At the same time, the stability of the existing drive device is poor, and the opening and closing of the car door during use has a large impact on the drive device, which can easily cause damage to the components inside the drive device. Therefore, it is necessary to develop a new type of drive device to solve the problems encountered during the use of the existing drive device. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a vehicle mid-door driving device which is convenient to use, simple to operate, has good stability, flexible transmission, and has good buffering capacity to reduce the impact caused by the opening and closing of the vehicle door, and has practicality and wide application.

[0005] In order to solve the above problems, the utility model adopts the following technical solutions:

[0006] A door drive device for an automobile comprises a first box body, a second box body, a control panel, a brushless motor, a gear transmission structure, a winding wheel and a guide wheel mechanism, wherein the first box body is connected to the second box body, the control panel, the brushless motor and the gear transmission structure are mounted in the first box body, the winding wheel and the guide wheel mechanism are mounted in the second box body, the brushless motor drives the winding wheel to rotate via the gear transmission structure, the gear transmission structure comprises a first gear, a second gear, a third gear and a fourth gear, the first gear is mounted at one end of the brushless motor, the second gear and the third gear are connected to form an integral structure, and the fourth gear is connected to the winding wheel via a fixed shaft.

[0007] The utility model realizes the automatic opening and closing operation of the vehicle door through the action of a brushless motor, a gear transmission mechanism and a winding wheel, through the control of a control panel and through the action of a pull rope.

[0008] Preferably, there are two guide wheel mechanisms, both of which include a guide wheel, a guide bracket and a spring. The guide wheel is mounted on the guide bracket, and the other end of the guide bracket is connected to the spring.

[0009] This arrangement, through the action of the spring, applies an elastic force or supporting force to the guide bracket and the guide wheel, so that the pull rope is always in a taut state, ensuring the normal operation of the pull rope; at the same time, when the car door is opened or closed, the pull rope is instantly subjected to increased force. At this time, the spring plays a better buffering role, reducing the direct force on the winding wheel, and providing better protection for the drive device.

[0010] Preferably, a slot is provided at one end of the guide bracket, and two sides of the guide wheel are arranged in the slot.

[0011] This arrangement realizes the installation of the guide wheel through the action of the slot and realizes the movable connection with the guide wheel.

[0012] Preferably, a guide groove is provided on the box body 2, and a portion of the guide bracket is embedded in the guide groove.

[0013] This arrangement realizes the positioning of the guide bracket and the control of the moving direction of the guide bracket.

[0014] Preferably, the box body 2 is provided with a wire drawing groove at the guide wheel.

[0015] This arrangement facilitates the connection and insertion of the drive device and the door connection pull rope.

[0016] Preferably, a mounting member 1 and a mounting member 2 are installed between the box body 1 and the box body 2.

[0017] This arrangement, through the functions of the first mounting member and the second mounting member, completes the rapid installation and fixation of the drive device on the vehicle, thereby increasing the convenience of installation.

[0018] The beneficial effects of the utility model are: easy to use, simple to operate, good stability, flexible transmission, and good buffering ability, which reduces the impact caused by the opening and closing of the car door. At the same time, the use of a brushless motor increases the safety during use and can meet the use requirements of a wide range of car models. It is practical and widely used.
