Description

Electric slide rail Technical Field The invention relates to the technical field of sliding rails, in particular to an electric sliding rail. Background The slide rail can bear a larger load, and can reciprocate along the linear track with less force. By utilizing the characteristics, more and more refrigerator products are loaded with sliding rail components, and storage components (drawers, racks and the like) which are small to the inside are large to the refrigerator door body. The conventional synchronous sliding rail is generally characterized in that the upper rail is stressed and moves along the front direction, the upper rail is correspondingly driven to move in the same direction as the upper rail under the action of the fixing of an upper rail belt, the belt drives the front synchronous wheel and the rear synchronous wheel to correspondingly rotate anticlockwise, meanwhile, the lower rail is fixed by a lower rail belt, the lower rail is provided with a fixed rail, the middle rail correspondingly moves along the same direction as the upper rail, the speed is one half of that of the upper rail, and the rear synchronous wheel is provided with a synchronous shaft which drives the sliding rail on the other side to synchronously move. The sliding rail is the same as the working principle from the opening state to the closing state, but the directions are opposite. The existing synchronous sliding rail lacks power and a transmission system thereof, and in the whole process, the manpower is required to continuously provide pulling/pushing force, and the sliding rail can move until the sliding rail is completely opened or completely closed. The guide rail is not able to move until fully opened or fully closed because of the manual effort required to continue providing the pulling/pushing force. This results in a number of inconveniences for the user in some scenarios. For example, when a user holds the article with both hands but needs to open the refrigerator, when the user with an older age bends down to take and put the refrigerator article, the user is difficult to perform continuous drawing operation, the sliding rail cannot be completely opened or closed, and the user experience is poor. Disclosure of Invention The invention aims to enable the sliding rail to be automatically opened and closed, and improve the use experience of a user. The invention further aims to reduce the feeling of the pause in the moving process of the sliding rail and improve the fluency. In particular, the invention provides an electric sliding rail.
