Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

The embodiment of the application provides an automobile, which can be any kind of automobile commonly seen in the market, such as a car, an MPV, an SUV and the like. The automobile comprises an automobile body and an automobile door 200, wherein an inlet and an outlet are formed in the automobile body, and the shape and the size of the automobile door 200 are respectively matched with the shape and the size of the inlet and the outlet one by one. When the door 200 closes the entrance, the door 200 is closed, and when the door 200 opens the entrance, the door 200 is opened.

Different from a side-hung rotating door-opening mode used on a traditional automobile, a sliding door driving mechanism 100 is installed between a vehicle door 200 and a vehicle body.

Referring to fig. 1, a sliding door drive mechanism 100 is shown in accordance with an embodiment of the present application. The sliding door driving mechanism 100 is used for connecting a vehicle door 200 and a vehicle body and enabling the vehicle door 200 to open or close in a side sliding manner relative to the vehicle body, and the sliding door driving mechanism 100 includes: a driver 10 for being mounted on the vehicle body; the driving wheel 20 is in driving connection with the driving part 10; the driven wheel 30 is in contact transmission fit with the driving wheel 20, and the rotation axis of the driven wheel 30 is parallel to the rotation axis of the driving wheel 20 in the vertical direction; and the swinging assembly 40 is in transmission connection with the driven wheel 30, and the swinging assembly 40 is used for being connected with the vehicle door 200.

In summary, the technical solution of the present embodiment has the following advantages: the sliding door driving mechanism 100 of the above-mentioned scheme is applied to an automobile, and is particularly used for connecting a vehicle body and a vehicle door 200, and enabling the vehicle door 200 to perform door opening or closing operations in a side sliding manner. Specifically, when the door 200 is opened from a closed state, the driving member 10 outputs a rotational power to drive the driving wheel 20 to rotate, the driving wheel 20 drives the driven wheel 30 to rotate synchronously, and the driven wheel 30 can further drive the swing assembly 40 to swing in parallel on a horizontal plane because the rotation axes of the driving wheel 20 and the driven wheel 30 are arranged in parallel in the vertical direction, so that the door 200 is opened in a trackless side-slipping manner under the driving of the swing assembly 40, and the occupied space after opening the door is small; in addition, even if the vehicle is collided laterally, the driven wheel 30 can rotate passively relative to the driving wheel 20 under the action of impact force, so that impact energy is eliminated, the sliding door driving mechanism 100 is prevented from being damaged, the vehicle door 200 can be ensured to normally slide and open when the vehicle is collided, and the use reliability is improved.

Preferably, on the basis of the above embodiment, the driving gear 20 is configured as a driving gear, and the driven gear 30 is configured as a driven gear, and the driving gear is meshed with the driven gear in a transmission fit. The driving gear is meshed with the driven gear, so that the transmitted power is more stable, the transmission efficiency is higher, the structure is simple, and the action and the position precision of the door opening or closing of the vehicle door 200 in a side-slipping mode are high.

Of course, in other embodiments, the purpose of improving the transmission stability and ensuring the transmission efficiency can also be achieved by arranging a concave-convex friction increasing structure on the wheel surface of the driving wheel 20 and/or the driven wheel 30, or arranging a layer of friction increasing pad on the wheel surface of the driving wheel 20 and/or the driven wheel 30.

In some embodiments, the drive gear has a diameter less than a diameter of the driven gear. The driving part 10 adopts a driving motor, the driving gear is directly connected with the driving motor, higher rotating speed can be obtained, and when the driving gear drives the driven gear to rotate, the rotating speed of the driven gear is slower, so that the stable opening and closing action of the vehicle door 200 is more facilitated.

It should be noted that, the diameter of the driving gear in other embodiments may be equal to or smaller than the diameter of the driven gear, and the diameter may be flexibly selected according to different working conditions.

Referring to fig. 1, in addition, in the above embodiment, the sliding door driving mechanism 100 further includes a transmission unit 50, the transmission unit 50 is in driving connection with the driving member 10, and the transmission unit 50 is in driving connection with the driving wheel 20. In operation, the transmission unit 50 can better transmit the rotational power output by the driving member 10 to the driving wheel 20.

For example, in the present embodiment, the transmission unit 50 is provided as a planetary reducer. When the rotary power output by the driving motor is transmitted to the planetary reducer, the planetary reducer can reduce the rotating speed, increase the torque, and improve the driving torque of the swing assembly 40, so that the opening and closing of the vehicle door 200 are reliable.

Referring to fig. 1, in some embodiments, the swing assembly 40 includes a fixed frame 41, a rotating shaft 42, and a swing arm 43, the fixed frame 41 is configured to be fixed on the vehicle body, the rotating shaft 42 is rotatably disposed on the fixed frame 41 and fixedly connected to the driven wheel 30, and the swing arm 43 is fixedly disposed on the rotating shaft 42 and connected to the vehicle door 200. The fixed frame 41 is fixedly connected with the vehicle body, and provides support for the rotating shaft 42 and the swing arm 43, so that the rotating shaft 42 and the swing arm 43 are ensured to rotate stably. The rotating shaft 42 and the driven wheel 30 are coaxially connected and fixed to each other, so that the driven wheel 30 can synchronously drive the rotating shaft 42 to rotate, and the rotating shaft 42 can further drive the swing arm 43 and the vehicle door 200 to swing, thereby realizing the side-sliding door opening or door closing operation of the vehicle door 200.

With reference to fig. 1, based on the above embodiment, the rotating shaft 42 includes a locking member 421, an end cap 422 and a shaft body, a first end of the shaft body is provided with a limiting plate 423, the shaft body is disposed on the driven wheel 30, the fixing frame 41 and the swing arm 43 in a penetrating manner, the limiting plate 423 is abutted against the driven wheel 30, a second end of the shaft body is fixedly connected to the end cap 422 through the locking member 421, and the end cap 422 is abutted against the fixing frame 41.

During installation, the second end of the shaft body sequentially penetrates through the driven wheel 30, the fixed frame 41 and the swing arm 43 until the limiting plate 423 is abutted against the wheel surface of the driven wheel 30, and the second end of the shaft body is positioned. The retaining member 421 is connected with the end cover 422 and the shaft body, the first end of the shaft body is locked and fixed, and all the parts of the rotating shaft 42 can be assembled and fixed. For example, the locking member 421 of the present embodiment is a bolt, and a threaded hole is formed on the second end surface of the shaft body, and the bolt is screwed into the threaded hole.

In addition, in order to improve the ability of the swing arm 43 to withstand a side impact, a reinforcing rib 44 is provided on the swing arm 43. The strengthening ribs 44 are arranged in a cross-shaped structure as in the present embodiment, which has a better strengthening effect on the swing arm 43.

Further, the swing arm 43 is rotatably connected to the vehicle door 200 by a pin. Also, the door 200 has rotational freedom compared to the swing arm 43, which can eliminate the manufacturing size and assembling size error, and ensure the door 200 to be closed tightly, and meanwhile, the door 200 can be buffered by rotation when being impacted laterally, thereby ensuring the self structure safety.
