Abstract

The utility model discloses an automatic tracking parasol. The parasol comprises an umbrella cover, an umbrella handle and a base, and further comprises light sensor pairs, a steering engine, a single-chip microcomputer and a storage battery, wherein each light sensor pair is composed of two light sensors which are arranged on the umbrella cover and symmetrical about the top of the umbrella, and the steering engine is mounted on the umbrella handle. The light sensors, the steering engine and the single-chip microcomputer are powered by the storage battery. The light sensor pairs are connected with the single-chip microcomputer, and the single-chip microcomputer is connected with the steering engine. The light sensor pairs collect light intensity signals and transmit the signals to the single-chip microcomputer, and the single-chip microcomputer determines whether the difference of the light intensity exceeds a preset threshold, and transmits a signal indicating whether steering engine should rotate or not. The automatic tracking parasol provided by the utility model is simple in structure and low in cost, and can effectively achieve the effect that the shade area does not move with the sun, thereby having relatively high economic value and wide application prospects.

Description

A kind of from the motion tracking parasols

Technical field

The utility model relates to the sun-shading equipment technical field, is a kind of from the motion tracking parasols specifically.

Background technology

The Climatic issues of bringing along with expanding economy are increasingly severe, and especially the problem such as ozone hole, climate warming has had a strong impact on people's life especially.Summer is more hot more a lot, it is exactly the reason of atmosphere, it is large that the kinetic energy of light particle becomes, thereby interior can also the raising than before much transformed, injury to human body is also large a lot, this is also the reason that present cutaneum carcinoma patient sharply increases, more obvious through the temperature difference of measuring sunshine direct projection district and shadow region, so the importance of sunshade is also more important more.Various parasols are also arranged on the market, but mostly these such umbrellas are that stiff fixing parasols, dirigibility is too poor, and often moved along with the movement of the sun in one day in the zone that it can cover.

The utility model content

The purpose of this utility model is for above-mentioned deficiency of the prior art, provide a kind of can follow the tracks of the sun, need not manual adjustments, round-the-clock sunshade from the motion tracking parasols.

The purpose of this utility model is achieved through the following technical solutions:

A kind of from the motion tracking parasols, comprise umbrella cover, umbrella handle and base, umbrella handle is erect and is fixed on base, also comprise that being symmetrical in the umbrella top is located at the optical sensor pair that every 2 optical sensors of umbrella cover form, be arranged on the steering wheel on umbrella handle, single-chip microcomputer and accumulator, described optical sensor, steering wheel and single-chip microcomputer are by storage battery power supply, described optical sensor pair is connected with single-chip microcomputer, single-chip microcomputer is connected with steering wheel, described optical sensor is passed to single-chip microcomputer to the intensity of illumination signal by collecting, single-chip microcomputer judges whether the difference of intensity of illumination surpasses default threshold values, send the signal whether rotated to steering wheel.

As preferred version, the steering wheel adopted has 2, be arranged on respectively middle and upper part and the bottom of umbrella handle, a steering wheel rotates on surface level by umbrella cover, another steering wheel rotates on vertical plane by umbrella cover, and each steering wheel has corresponding optical sensor pair, and described optical sensor is to being uniformly distributed on umbrella cover, be each optical sensor and adjacent optical sensor 90 degree of being separated by, every pair of two right optical sensors of optical sensor 180 degree of being separated by.The every pair of optical sensor pair and single-chip microcomputer and corresponding steering wheel form a road control circuit, and two steering wheels just have the two-way control circuit.

Described accumulator is chargeable storage, and having strengthened can be in the wild or interim place applicability.

The ultimate principle of the device the utility model proposes is: be uniformly distributed four sensors on umbrella cover and detect, these four sensors 90 degree of being separated by between detecting, the sensor of every two 180 degree of being separated by is one group, form optical sensor pair, whether whether sensor controls corresponding steering wheel over threshold value according to the difference of the data of two sensors detections of one group of optical sensor centering is rotated.In umbrella bar middle and upper part and bottom, a steering wheel is arranged respectively, the steering wheel of middle and upper part can allow umbrella cover rotate on vertical plane, and the steering wheel of bottom can make umbrella cover rotate on surface level.The utility model adopts the sensor technology perception sun to move the variation that latter two optical sensor detects data difference, and after processing by single-chip microcomputer, output control signal control steering wheel rotates, and can adjust effectively and timely the position of umbrella cover, realizes effective sunshade.

The utlity model has following outstanding beneficial effect: the utility model is simple in structure from the motion tracking parasols, cost is low, can effectively realize that shadow region is not moved with the sun and mobile effect realizes that commercialization has higher economic worth and wide application prospect.
