Description

Rotating mechanism and foldable electronic equipment Technical Field The present application relates to the field of electronic products, and in particular, to a rotating mechanism and a foldable electronic device. Background The rotating mechanism has become one of the essential core components of the foldable electronic device, wherein the shaft cover and the supporting plate serve as important components of the rotating mechanism, and the reliability of the fixed connection of the shaft cover and the supporting plate can influence the reliability of the whole machine. However, as the foldable electronic device is gradually developed, the size thereof is gradually reduced, and the rotating mechanism is continuously thinned and narrowed, so that the space between the shaft cover and the supporting plate is very limited, which results in very limited space reserved for the connecting piece for connecting the shaft cover and the supporting plate, and further, the reliability of the fixed connection between the shaft cover and the supporting plate is low. Disclosure of Invention The application provides a rotating mechanism and a foldable electronic device, which can ensure reliable connection of a supporting plate and a shaft cover. The first aspect of the application provides a rotating mechanism comprising a shaft cover, a supporting plate and a connecting piece, wherein the shaft cover comprises a body part and two first mounting parts, the body part comprises a setting surface, and the setting surface extends along the length direction of the rotating mechanism. Along the length direction of the rotating mechanism, two first installation parts are respectively arranged at two ends of the setting surface in a protruding mode, and the two first installation parts are opposite at intervals. The backup pad is equipped with two second installation department, and two second installation department are located the backup pad along the opposite both ends of slewing mechanism's length direction. The support plate is laminated on the support surface of the body in the thickness direction of the rotation mechanism. The backup pad is located the interval between two first installation department, and two first installation department and two second installation department butt respectively. Along the length direction of the rotating mechanism, one end of the connecting piece is fixed on the first installation part, and the other end of the connecting piece is fixed on the second installation part. It will be appreciated that the rotating mechanism is applied to a foldable electronic device and that the surface of the support plate facing away from the shaft cover is used to support a display screen of the foldable electronic device. In the related art, the supporting plate and the shaft cover are fixedly connected through a screw, the rod part of the screw is fixed on the shaft cover, the nut of the screw is fixed on the supporting plate, and the surface of the nut, which is opposite to the supporting plate and is away from the shaft cover, is exposed, namely the nut faces the display screen of the foldable electronic device. At this time, the direction of the fixing force between the shaft cover and the support plate is parallel to the thickness direction. However, as the rotating mechanism is continuously thinned, the space in the thickness direction is very limited, so that the nut interferes with the display screen, and at the moment, once the foldable electronic equipment falls, the nut can impact the display screen, so that the display screen is damaged. In addition, the smaller Z-direction space can only accommodate screws with shorter rod parts, so that locking teeth on the rod parts are shorter, and finally, the connection reliability of the shaft cover and the supporting plate is insufficient. In addition, because the shaft cover is thin, the interval between the bottom of the screw and the appearance surface of the shaft cover is very small, and gravure is easily generated on the appearance surface of the shaft cover. In the application, the first mounting part and the second mounting part are arranged along the length direction and are fixedly connected by the connecting piece, and the fixing force between the supporting plate and the shaft cover is parallel to the length direction. The fixing mode mainly occupies the space in the length direction, and the space requirement in the thickness direction is small. The support plate and the shaft cover can be reliably connected, the display screen cannot be interfered, the display screen is prevented from being damaged, gravure on the appearance surface of the shaft cover can be prevented, and the appearance fineness of the shaft cover is improved. In some embodiments, one of the first mounting portion and the second mounting portion is provided with a locking aperture and the other is provided with a mounting structure. One end of the connecting piece is fi
