Description

Rotating structure capable of preventing motor from being blocked and mobile phone support Technical Field The utility model relates to the technical field of electronic product application, in particular to a rotating structure capable of preventing a motor from being blocked and a mobile phone support. Background Along with the popularization of the intelligent mobile phone, the intelligent mobile phone is used more and more frequently in daily life and work of people, and the functions are also diversified more and more. The mobile phone support is used as an auxiliary tool, so that a user can watch videos, conduct video call, browse webpages and the like in different scenes conveniently, and the market demand is growing increasingly. However, the existing mobile phone support has a plurality of problems in the use process, so that the improvement of user experience is limited. The limitation of manual adjustment, the traditional mobile phone support mostly adopts a manual angle adjustment mode, and a user needs to manually stir or rotate the support to adjust to a proper angle. The mode is inconvenient to operate, and particularly when the hands of a user are busy (such as cooking, driving and other scenes), the angle of the bracket is difficult to adjust quickly. Moreover, the manual adjustment precision is low, fine angle adjustment is difficult to realize, and the diversified requirements of users on different use scenes cannot be met. In recent years, some mobile phone supports with electric adjustment angles gradually appear, and an automatic adjustment function is realized through a built-in motor, so that the convenience of use is improved to a certain extent. However, in practical use, the mobile phone support with electric adjustment also exposes some problems. For example, when the motor encounters excessive resistance or seizing during rotation, the motor is liable to burn out. This is because the motor continuously outputs a large current when it is stuck, and the excessive current may damage the coil, brush, etc. inside the motor, thereby affecting the service life and reliability of the mobile phone holder. In addition, the structural design of current electric mobile phone support is unreasonable enough, and the motor appears not hard up or wearing and tearing with the junction of support easily, has further reduced the stability and the durability of product. The function is single, except the problem of regulation mode, and current cell phone stand's function is comparatively single, can't satisfy the diversified demand of user. Along with the development of science and technology, the mobile phone is not only used for communication and entertainment, but also matched with intelligent home, intelligent wearing equipment and the like. For example, many users wish to be able to conveniently charge a mobile phone wirelessly or to charge a device such as a smart watch while using a mobile phone cradle. However, most of the mobile phone holders currently only have basic supporting functions, and lack of support for these additional functions limits the application scenarios in modern life. The appearance and the practicality are not enough, and from the appearance design, the design of current cell phone stand is comparatively simple, lacks aesthetic property and individuation. In modern home and office environments, consumers are not only focusing on the practicality of the product, but also have higher requirements on the design of the appearance of the product. In addition, the internal wiring design of the existing mobile phone support is unreasonable, and the exposed wires not only affect the appearance, but also can cause the problems of wire abrasion, short circuit and the like, and potential safety hazards exist. In summary, the existing mobile phone support has certain defects in the aspects of adjustment mode, structural design, functional diversity, appearance practicability and the like, and cannot meet the requirements of modern consumers on the mobile phone support with high quality, multiple functions, attractive appearance and practicability. Therefore, it is necessary to design a novel mobile phone support, solve the problem that current product exists, promote user experience, satisfy the demand of market to high performance mobile phone support. Disclosure of Invention Aiming at the defects, the utility model aims to solve the problems that the existing mobile phone support is difficult to be compatible with manual and electric operation and is easy to be blocked and burnt out due to large current when a motor rotates. In order to solve the problems, the utility model particularly provides a rotary structure with a motor blocking prevention function, which is characterized in that a base is connected with a supporting rod through a first rotating shaft mechanism, the first rotating shaft mechanism comprises a rotating shaft arranged at the upper part of the base, a motor f
