Description of the invention: [Technical field to which the invention pertains] The present invention relates to an umbrella body, and more particularly to an umbrella body that can be automatically opened and closed. [Prior Art] According to the current, most of the umbrellas on the market require the user to personally do the work of opening and closing the umbrella with the hand. The opening and closing action of this type of umbrella must be with both hands. That is, we must first hold the grip of the umbrella with one hand and push the umbrella with the other hand through the sleeve of the rib to make the umbrella cloth up, so it is quite troublesome to operate; If the user's hand holds other items, the item must be put down first, and the opening and closing of the umbrella can be operated. It is quite inconvenient to use. Secondly, the hand is often used by the umbrella to limit the item. The hook of the sleeve is moved, so the operation safety needs to be improved. In view of the above-mentioned shortcomings, there is an umbrella that uses the power spring as the power to drive the sleeve to move upward to achieve the opening of the umbrella. The opening operation of the umbrella does not require the use of both hands, so the operation is relatively simple, and If the user holds the item on his hand, the use of the umbrella is also convenient, and the hand is not easily damaged; however, the closing action of the umbrella must still be performed by both hands. Wherever the money is used and used; in addition, when the above-mentioned umbrella is applied to the sunshade of the outdoor table, the user must personally open the umbrella to shade or close the umbrella, but the umbrella Both are relatively large and cumbersome, which is more inconvenient to cause the operation and use of the umbrella to open and close. In view of this, the inventor of this case has been carefully researched and accumulated years of experience in research and development and manufacturing in related industries, and finally has the invention. SUMMARY OF THE INVENTION In view of the above-mentioned deficiencies, it is an object of the present invention to provide an umbrella that can be automatically opened and closed, which can be automatically opened and closed by side light, which is convenient for the user to operate and convenient to use. In order to achieve the above object, the present invention provides an umbrella that can be automatically opened and closed, including a hollow shaft tube, a head cover, a grip, a sleeve, an umbilical group, a power unit, a light sensor, a screw, a nut, and a fixing member; the hollow shaft tube has a top end, a bottom end, and a long groove disposed between the top end and the bottom end, the head sleeve is disposed at a top end of the hollow shaft tube, a grip is disposed at the bottom end of the hollow, the bribe is movably sleeved outside the hollow shaft, and is located between the head cover and the grip, the stalk end-end is inserted into the sleeve, and the other end is The power unit is pivotally connected to the handle, and the power unit is disposed in the grip body, and is electrically connected to the axial force unit. The screw is disposed in the hollow shaft tube, and the end thereof is connected to the head sleeve. The other end is connected with the power single unit 'the screw can be rotated by the power single core and screwed on the screw' and can be displaced along the axial direction of the mechanical pure with the rotation of the screw, and the member passes through the shaft Long slots are locked to the nut. Therefore, when the light sensor side reaches a predetermined amount of light, the power unit can be driven to drive the screw, so that the nut moves to synchronously drive the axial displacement of the sleeve along the 201132314, and the The rib group is opened or closed to achieve the function of automatically opening and closing the umbrella body, which is convenient for the user to use. The embodiments of the present invention are described in detail below with reference to the accompanying drawings, wherein: The structure diagram of the expanded state. Fig. 1 is a structural view showing the umbrella body in an unfolded state according to a preferred embodiment of the present invention. "Monthly, as shown in Fig. 1 is an umbrella body 10 which can be automatically opened and closed according to a preferred embodiment of the present invention. The structure of the umbrella body 1G includes a hollow shaft tube 12, . . The head cover 13, a grip 14, a sleeve 15, an rib group, a power unit 17, a screw 18, a nut 19, a fixing member 2, and a photosensor 21 〇a have a working shaft S 12 A top end 121 and a bottom end 122' and a side turn between the top end 121 and the money end 122 are axially open-long slots (2). The head cover 13 is sleeved on the top end 121 of the hollow shaft tube, and has a bottom 14 at the bottom end m of the hollow shaft tube 12 for holding, and has a chamber 141 therein, which is suitable for The hollow shaft tubes 12 are internally connected to each other. The sleeve 15 is a cylindrical body that is sleeved on the hollow shaft tube two towing portion 151 and is movable between the head cover 13 and the grip 201132314. The rib group 16 is composed of a plurality of sets of radiatingly arranged financial arms (6), and is covered with an umbrella-not shown; the elbow branch f i6i _ end is pivotally connected to the head cover 13 The portion 131 is pivotally connected, and the other end is coupled to the second plumbing portion 151 of the sleeve 15. When the sleeve 15 is moved, each of the financial arms 161 will be unfolded or folded, so that the rib group 16 can be _ expansion state S1 (as shown in the second figure) and - undeployed state S2 (such as the first figure); the power unit 17 has a - switch m, - motor 172 and _ battery, s-switch 171 is located in the The grip 14 is exposed on the outside and electrically connected to the 172 and the battery 173. The screw 18 is axially disposed in the hollow shaft tube 12, and has one end connected to the head sleeve 13 and the other end connected to the motor 172 of the power unit 17, and is rotatable by the motor 172. The nut 19 is screwed to the screw 18 and is displaceable along the axial direction of the hollow shaft 11 as the screw a expands. The fixing member 20 is a bolt in the embodiment, and is fastened to the fixing member 2 through the sleeve μ and the long groove 123 of the hollow tubular body 12, so that the sleeve 15 can be The nut 19 is displaced synchronously; it should be noted that the nut 19 is limited to move within the long groove 123 of the hollow tubular body 12. The light sensor 21 is a device capable of detecting the light content, and is electrically connected to the power unit 17 for detecting the external light intensity, and according to the control signal to the power unit π, The power unit 17 controls the screw to operate; in detail, when the light content detected by the light sensor 21 is higher than the first value, the light sensor 21 sends a first signal to the motor, 2011201132314 The moving edge motor 172 drives the screw is, moves the nut Μ upward, and synchronously drives the sleeve 15 to move upward, thereby unfolding the elbow arms 161 ′ of the rib group ι6 so that the umbrella body 1 is unfolded State S1; when the light content of the side of the photosensor 21 is lower than the second set value, the photosensor 21 sends a second signal to the motor 172' to drive the motor 172 to drive the screw in the opposite direction. 18' causes the job 19 to move downward, and simultaneously drives the sleeve I5 to move downward, thereby folding the elbow arms 161 of the bolster group 6, so that the umbrella body 10 is in an unexpanded state; It can be seen that the umbrella 1 of the present invention is used for the purpose of automatic opening and closing by the weight measurement of the debt. Compared with the manufacturer's umbrella structure, the user can operate the umbrella body ω without opening and closing, so that the operation is quite simple, and the user operates the umbrella body ω at the same time. Other items can be slammed (4) 1G operation; in addition, such as Shuming's technique f is used for outdoor «Square material of the county to overcome the user's time spent in the opening and closing of the umbrella body and cost ^1 As described above, HI is an umbrella of the present invention, and has advantages. Fang Bao is easy to use and easy to use. However, the above-mentioned ones are only preferred of the present invention. Any application should be made in the application of the invention. The change should be included in the invention.
