Abstract

The utility model relates to a full-automatic umbrella, which is controlled by a pushbutton (9) arranged on the full-automatic umbrella handle (5) to be opened and to be closed automatically. The utility model can be provided with motive power by an electric motor (7) arranged in the full-automatic umbrella handle (5) and the motive power is accumulated by a spring; so the motive power can be released in the processes of opening and closing the full-automatic umbrella to push the relevant positions of the full-automatic umbrella to move and to complete the automatic opening and closing of the full-automatic umbrella.

Description

Full-automatic umbrella

Full automatic umbrella is a kind of umbrella that can automatic switch, is a kind of daily necessities of automation.

In the existing umbrella, nonautomatic umbrella needs both hands manually opened, manual-lock; Though umbrella can be opened automatically automatically, can not close automatically, still need when closing manually and to require great effort.All these umbrellas are switch fully automatically all, uses very inconvenience many time.

The utility model aims to provide manual operating of a kind of need, can open the automatic umbrella that can close automatically again automatically.This umbrella so the required power of the switch of umbrella need provide separately, therefore is provided with power supply and motor owing to do not use the manpower switch in umbrella, this is a first feature of the present utility model; But within the scope that the volume of umbrella can hold, no matter be power supply or motor, all can't be in the extremely short time, providing is enough to energy that umbrella is opened or packs up, so the utility model is provided with a spring mechanism, the power that motor was provided in a period of time by it changes elastic potential energy into to be put aside, and with this huge elastic potential energy umbrella is opened or packs up in the moment of umbrella opener, and this is a second largest feature of the present utility model.

The utility model---full automatic umbrella is made up of canopy and handle of umbrella two parts.The canopy part is by umbrella cloth (1), umbrella frame formations such as (2), and its structure and existing folded umbrella are basic identical; The handle of umbrella part is made of handle (5), metallic rod (4) and metal loop bar (3), metal loop bar (3) is enclosed within on the metallic rod (4), constitute Collapsible structure, metal loop bar (3) upper end is connected with umbrella frame (2) top, and metallic rod (4) lower end is connected with handle (5).Be provided with power supply (6) (dry cell or battery), micromotor (7), speed changer (8) and circuit etc. in the handle (5), its switch for whole umbrella provides driving source.The outside of handle (5) is provided with the button (9) of the switch of a control umbrella.Be provided with in the metallic rod (4) along its axial screw rod (10) and in order to keep the bearing (22) of screw rod (10), speed changer (8) in one end of screw rod (10) and the handle (5) links to each other, be with nut (11) on the screw rod (10), nut (11) slides along metallic rod (4) during screw rod (10) rotation, nut (11) is connected with an end of the spring mechanism that is positioned at metallic rod (4) (12), the other end of spring mechanism (12) extends in the metal loop bar (3), be connected with the top of metal loop bar (3), spring mechanism (12) can be by a spring, or formations such as several spring and support.Metal loop bar (3) is provided with pulley (13), pulley base (14), flexible lock pin (15) etc., has two holes (16,17) on metallic rod (4), goes into for flexible lock pin (15) pin.Also be provided with a thin gangbar (19) in the metallic rod (4), it is subjected to nut (11) effect, stirs flexible lock pin (15) when umbrella opener, and can stir the motor commutation switch (21) that is positioned at metallic rod (4) lower end.The umbrella frame hub tube (18) of canopy part links to each other with the upper end of metallic rod (4) by the pulley (13) on the metal loop bar (3) with rope (20), so that metal loop bar (3) is when moving, umbrella frame (2) can link with it.

The running of full automatic umbrella when switch as shown in Figure 2.When umbrella was in collapse state, the nut (11) in the metallic rod (4) was positioned at the upper end of screw rod (10), and spring mechanism (12) is in complete compressive state.When umbrella need be opened, press the button (9), circuit is connected, motor (7) begins to rotate, by speed changer (8), screw rod (10) promotes nut (11) to be continued to move up, stir gangbar (19) and further compress spring mechanism (12), gangbar (19) at first rushes open flexible lock pin (15), make it to break off relations, promptly under the elastic force effect of spring mechanism (12), made progress ejects rapidly metal loop bar (3), and umbrella frame hub tube (18) is also because of rope (20) interlock simultaneously, metal loop bar (3) moves upward relatively, and umbrella frame (2) begins to open (Fig. 2 I).When metal loop bar (3) moved to the top, in flexible lock pin (15) the pin hand-hole (16), metal loop bar (3) and metallic rod (4) pin is extremely fixing, and umbrella frame this moment (2) opened fully, and nut (11) is still moving up.Gangbar (19) is further stirred motor commutation switch (21), and motor (7) change turns to, and nut (11) begins to move downward, with spring mechanism (12) stretching (Fig. 2 II).When nut (11) moves to screw rod (10) lower end, motor (7) stall, nut (11) stop motion, spring mechanism this moment (12) is in complete extended state, this state will be retained to next time and close, and provide power, opening process so far to finish (Fig. 2 III) for closing.The pass closed procedure and the opening process of umbrella are similar, press the button (9), circuit is connected, nut (11) continues to move down, drive gangbar (19) and rush open flexible lock pin (15), metal loop bar (3) moves rapidly downwards under the elastic force effect of spring mechanism (12), and umbrella frame (2) also begins to pack up (Fig. 2 IV).Metal loop bar (3) is when moving to the end, in flexible lock pin on it (15) the pin hand-hole (17), metal loop bar (3) and metallic rod (4) pin is extremely fixing, umbrella frame this moment (2) is packed up fully, gangbar (19) is further stirred motor commutation switch (21), motor (7) change turns to, and nut (11) begins to move upward, with spring mechanism (12) compression (Fig. 2 V).On nut (11) moves to screw rod (10), motor (7) stall, spring mechanism (12) keeps complete compressive state, closes closed procedure and finishes (Fig. 2 VI).Of the present utility modelly open or close the motor power of once closing or open the back savings before all being each time and finished, need certain interval of time so open or close at every turn.

The utility model compared with prior art, characteristics are that it is easy to use.Existing umbrella is switch fully automatically all, as user during only with a manual operating, then can't maybe can only open and can not close by switch, uses inconvenience.And the utility model---full automatic umbrella is power with the motor, and the user can make it automatic switch with a hand leggiero, as long as can just can handle its switch with hand-held umbrella, uses very convenient.Because the driving of motor is only when opening and closing, and the use of umbrella is not very frequent, so as a whole, the utility model is power saving very.When not needing automatic switch, also can manually make it switch, this moment, it was equivalent to an existing folded umbrella.

The equal special-less process requirement of the manufacturing of all parts of the utility model, umbrella cloth (1), umbrella frame (2), metal loop bar (3), metallic rod (4) etc. are basic identical with the method for making of existing folded umbrella.
