Description

Technical Field

[0001] This utility model relates to the field of automotive door technology, and in particular to a simple electric sliding door drive system. Background Technology

[0002] As people's living standards continue to improve, cars are being used more and more in people's lives. There are many types of cars, which can be classified according to their uses, including cars, buses, and trucks. Among them, small vans are widely used in many industries because they are inexpensive and economical. Small vans are equipped with sliding side doors, which are used to open and close the car body by sliding horizontally.

[0003] However, many car sliding doors are currently opened and closed manually, which may be difficult for people with less strength, sometimes requiring them to open the sliding door while reaching for something.

[0004] The existing technology, application number CN201821869886.3, is a car door drive mechanism. Its structure is complex, its overall layout occupies a large area, and its installation is difficult.

[0005] Therefore, a simple electric sliding door drive system needs to be designed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a simple electric sliding door drive system to overcome the above-mentioned shortcomings of the existing technology.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A simple electric sliding door drive system includes a slide rail, a lower sliding door guide rail placed on the slide rail, a belt drive module placed inside the slide rail for driving movement, and a sliding assembly driven by the belt drive module and installed along the slide rail. The sliding assembly includes a connecting bracket connected to a car door panel, a lower sliding door hinge located at the bottom front end of the connecting bracket, an upper sliding door hinge located at the upper front end of the connecting bracket, a sliding plate connected to the lower sliding door hinge via a connecting shaft and placed inside the slide rail, lower rollers respectively located around the bottom of the sliding plate and respectively abutting against the inner wall of the slide rail, a belt fixing bracket connected to the sliding plate via bolts and fixed to the belt drive module, an upper connecting block connected to the upper sliding door hinge, and upper rollers respectively located on both sides of the upper connecting block and placed inside the lower sliding door guide rail for sliding.

[0009] Preferably, the belt drive module includes a drive motor located at one end of the slide rail, a main roller driven by the drive motor, a transmission roller 33 located at the other end of the slide rail, and a transmission belt arranged around the main roller and the transmission roller and placed within the slide rail.

[0010] Preferably, a limiting U-shaped plate is also provided on the transmission belt.

[0011] Preferably, the drive motor is mounted on a bracket.

[0012] The beneficial effects of this utility model are: This technical solution realizes the opening and closing of the entire car door by setting a simple belt transmission. The drive wheel moves along the front and rear direction of the vehicle under the drive of the belt, thereby driving the lower hinge to move in the front and rear direction. Since the lower hinge is fixedly connected to the sliding door, the sliding door can be opened and closed electrically. The structure of synchronous upper and lower drive sliding is simple and low cost. Attached Figure Description

[0017] Reference Figures 1 to 3 A simple electric sliding door drive system includes a slide rail 1, a lower guide rail 2 placed on the slide rail, a belt drive module 3 placed inside the slide rail and used for driving movement, and a sliding component 4 driven by the belt drive module and installed along the slide rail.

[0018] The belt drive module 3 includes a drive motor 31 located at one end of the slide rail, a main roller 32 driven by the drive motor, a transmission roller 33 located at the other end of the slide rail, and a transmission belt 34 arranged around the main roller 32 and the transmission roller 33 and placed within the slide rail. The drive motor 31 drives the main roller 32 to rotate, and with the assistance of the transmission roller 33, the transmission belt rotates, thereby driving the sliding component 4 fixedly installed on the transmission belt to move.

[0019] To limit the transmission belt and prevent it from shaking during transmission, a limiting U-shaped plate 35 is also provided on the transmission belt. The limiting U-shaped plate covers the transmission belt and is fixedly installed in conjunction with the slide rail, thereby limiting the position of the transmission belt and preventing it from shaking during transmission, which would affect the accuracy and efficiency of the sliding component 4.

[0020] In order to install the drive motor, the drive motor is fixed by mounting bracket 36;

[0021] The sliding assembly 4 includes a connecting bracket 41 that connects to the car door panel, a lower sliding door hinge 42 located at the bottom front end of the connecting bracket, an upper sliding door hinge 43 located at the top front end of the connecting bracket, a sliding plate 45 connected to the lower sliding door hinge 42 via a connecting shaft 44 and placed within the slide rail, lower rollers 46 respectively located around the bottom of the sliding plate and respectively attached to the inner wall of the slide rail, a belt fixing bracket 47 connected to the sliding plate via bolts and fixed to the transmission belt, an upper connecting block 48 connected to the upper sliding door hinge, and upper rollers 49 respectively located on both sides of the upper connecting block and placed within the lower sliding door guide rail 2 for sliding cooperation.

[0022] The entire sliding assembly 4 is connected to the belt fixing bracket 47, which is fixed to the transmission belt. When the transmission belt is driven, the belt fixing bracket 47 moves synchronously. At the same time, the lower roller 46 supports the inner wall of the slide rail to assist in sliding, while the upper roller 49 supports the inner wall of the lower track 2 of the sliding door to assist in sliding, thereby realizing the upper and lower track driving and sliding, which greatly increases the driving efficiency.

[0023] The advantages of this utility model are that the technical solution achieves the opening and closing of the entire car door by setting a simple belt transmission. The drive wheel moves along the front and rear direction of the vehicle under the drive of the belt, thereby driving the lower hinge to move in the front and rear direction. Since the lower hinge is fixedly connected to the sliding door, the sliding door can be opened and closed electrically. The structure adopts a structure of synchronous upper and lower drive sliding, which is simple and low in cost.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
