Embodiment Construction
[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.
[0028] It should be noted that when an element is referred to as being “fixed on”, “disposed on” or “installed on” another element, it may be directly on the other element or there may be an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be an intervening element at the same time; the specific way that one element is fixedly connected to another element can be realized through existing technologies, and will not be discussed here. To repeat it agai...

The invention relates to a damping reduction box, a power operated tailgate and an automobile. The damping reduction box comprises a box shell, a power output shaft, a first inner gear ring and a friction plate, wherein the output port of the box shell is provided with a bearing, the power output shaft is arranged in the box shell and one end of the power output shaft is sleeved with the bearing,a first tooth structure is arranged on the outer wall of the power output shaft, the first inner gear ring is sleeved outside the power output shaft and is in meshing transmission with the first toothstructure, the friction plate is sleeved on the power output shaft and is in close contact with the end face of the first gear ring, the friction plate is fixed to the inner box wall of the box shell, and the first gear ring can rotate oppositely to the friction plate. Compared with the traditional way of adding a damper additionally, the scheme enhances the internal resistance by improving the internal structure of the traditional box shell, so the damping reduction box does not cause the problems of occupying the space of a trunk and increasing costs, and the damping reduction box is beneficial to improving the production economy of manufacturers and reducing the cost of users.
Description
technical field [0001] The invention relates to the technical field of auto parts, in particular to a damping reduction box, an electric tailgate and an automobile. Background technique [0002] At present, the opening and closing action of the tailgate of the automobile all relies on the strut to realize. The strut is generally a telescopic rod structure. When it is extended, the tailgate is lifted and opened, and when it is retracted, the tailgate is lowered and closed with the car body. For some special types of vehicles, such as SUVs and pickups, the weight of the tailgate is relatively large, so that the internal resistance of the strut itself is not enough to support the weight of the tailgate. In this case, it is necessary to add additional dampers to the strut. However, adding a damper will bring other problems: adding a damper will directly lead to an increase in manufacturing costs, which will increase the economic burden on the company and customers; in addition,...
