Full-automatic opening and closing umbrella

Abstract

The invention discloses a full-automatic opening and closing umbrella which comprises a middle rod (1), an upper nest (21), a lower nest (22), an umbrella handle (3) and umbrella ribs (4). The middlerod (1) is formed by sleeving at least two sections of pipe fittings from inside to outside in a sliding manner, and comprises a first pipe fitting (11) connected with the umbrella handle (3) and a second pipe fitting (12) adjacently sleeved with the first pipe fitting (11); a motor (5) is arranged in the umbrella handle (3), and an output shaft of the motor (5) is connected with a transmission piece arranged in an inner cavity of the first pipe fitting (11); a rack (7) is fixedly arranged in the second pipe fitting (12) in the length direction of the second pipe fitting (12), a structure meshed with the rack (7) is arranged on the transmission piece, and the motor (5) rotates to drive the rack (7) to move upwards or downwards through the transmission piece. According to the full-automaticopening and closing umbrella, power is transmitted through the transmission piece arranged on the first pipe fitting and the rack arranged in the second pipe fitting, work is more reliable and durable, the structure is simple, and automatic stretching and retracting of the middle rod can be achieved.

Description

technical field [0001] The invention relates to umbrellas for daily use, in particular to an electric folding umbrella with the function of automatic opening and closing. Background technique [0002] The automatic opening and closing umbrellas on the market are mainly mechanical and electric. The control of the mechanical opening and closing umbrella is mainly through the opening spring, the bullet, and the bullet connected to the bullet in the middle rod of the umbrella. It is realized by going around the middle rod and the cable of the pulley set on the lower nest, the complex control device set in the umbrella handle and many other components. By pressing the control button on the umbrella handle, the umbrella can be automatically opened and folded automatically. However, after the umbrella cover is folded, the user still needs to forcefully compress the tubes of the unfolded middle rod until they are locked to completely retract the umbrella. Moreover, in order to prev...

Problems solved by technology

This has further caused the structure of this automatic opening and closing umbrella to be quite complicated, with a lot of parts, and it is also difficult to assemble, which increases the cost of the umbrella, and the work is not reliable enough.

And the structure of electric type is as disclosed in the Chinese utility model patent of CN205813811U as notification number, mainly is to drive the pulley and the pulley that are arranged in the middle stick by the motor in the umbrella handle to control the expansion and contraction of each section of the middle stick. Although this structure is relatively simple, all the power of each section of the rod in the deployment needs to be transmitted through the pull rope in the pipe connected to the umbrella handle, which makes it more difficult to open the umbrella, and the pull rope is easily damaged after long-term use. And the problem that the umbrella cannot be used
