however, the existing water rocket cannot record the flying height, because the power of the water rocket is limited, strict requirements are imposed on the weight and the volume of the rocket body, if the weight of the altimeter is too large, the gravity center position of the water rocket can be changed, the flying height of the water rocket is influenced, the measured data is inaccurate, and therefore the altimeter which is extremely light in weight and cannot influence the flying of the water rocket is designed.
The utility model has the following contents:
the utility model aims at overcoming the weak point of current product, provide an aircraft model is with miniature utmost point light weight gauge.
The utility model adopts the technical proposal that: a micro extremely light height gauge for an aircraft model is provided with a micro PCB, wherein a microprocessor, an air pressure sensor and a switch are attached to the back of the PCB, the front of the PCB is connected with a battery guide positioning cover, and a space for accommodating a button battery is formed between the battery guide positioning cover and the PCB; wherein:
a plurality of digit indication LED lamps which are distributed at intervals are attached to the front surface of the PCB and between one side of the battery guide connection positioning cover and the edge of the PCB; a digital display LED lamp group capable of presenting digital 0-9 patterns is attached between one side of the battery guide positioning cover and one corner of the PCB.
The number of the digit indication LED lamps is four, and the number of the digit indication LED lamps is a hundred digit indication LED lamp, a ten digit indication LED lamp, a single digit indication LED lamp and a ten decile digit indication LED lamp.
The digital display LED lamp group comprises seven LED lamps, and one of the numbers 0-9 is displayed by lighting at different positions in the seven LED lamps.
One corner of the PCB is provided with an inner concave unfilled corner, the switch is attached to the edge of the inner concave unfilled corner, and the shifting piece of the switch protrudes out of the inner concave unfilled corner.
The altimeter has a weight of less than or equal to 1.3 grams without a button cell and a weight of less than or equal to 1.9 grams with a button cell.
The utility model discloses an above-mentioned structure, through the cooperation of four number indication LED lamps and digital display LED banks, the simple computational formula of rethread obtains measured altitude value to can save and adopt liquid crystal display to show the height, and then can reduce the volume, the weight of altimeter, make the weight of altimeter alleviate extremely, no longer than 1.9g, can not influence the flight of water rocket basically.
Description of the drawings:
fig. 1 is a schematic view of the structure of a micro ultra-light weight gauge for an aircraft model.
The specific implementation mode is as follows:
the present invention will be further described with reference to the following specific embodiments and accompanying drawings.
As shown in fig. 1, a micro extremely light height gauge for an aircraft model, the height gauge comprises a micro PCB 1, a microprocessor, an air pressure sensor (not shown in the figure) and a switch 2 are attached to the back of the PCB 1, a battery lead positioning cover 3 is connected to the front of the PCB 1, and a space for accommodating a button battery is formed between the battery lead positioning cover 3 and the PCB 1; wherein:
a plurality of digit indication LED lamps 4 which are distributed at intervals are attached to the front surface of the PCB 1 and between one side of the battery guide connection positioning cover 3 and the edge of the PCB; a digital display LED lamp group 5 capable of presenting digital 0-9 patterns is attached between one side of the battery guide positioning cover 3 and one corner of the PCB board 1.
The number of the digit indication LED lamps 4 is four, and the number of the digit indication LED lamps is a hundred digit indication LED lamp 41, a ten digit indication LED lamp 42, a single digit indication LED lamp 43 and a ten decile digit indication LED lamp 44; they respectively correspond to the hundred digit indication, the ten digit indication, the unit digit indication and the ten decile digit indication;
the digital display LED lamp group 5 comprises seven LED lamps, and one of the numbers 0-9 is displayed by lighting of different positions of the seven LED lamps.
When the height gauge is used, the button battery is firstly installed, then the switch 2 is turned on, the height gauge performs self-checking, and after all the LED lamps are sequentially lightened once or twice, the self-checking is completed after the LED lamps are ensured to be free of faults; when the altimeter is lifted to the highest point along with an aircraft such as a water rocket and the like, the highest value is measured and recorded, and the display form of the highest value is as follows: the four-digit indication LED lamp flashes from high position to low position in a rotating mode, and the digital display LED lamp group changes the displayed digits correspondingly, for example, when the hundred-digit indication LED lamp 41 flashes, the digital display LED lamp group displays a digit such as "8" and then flashes, which means that the hundred digits of the height value are "8", namely 800; then, when the digit indication LED lamp is switched to the tens indication LED lamp 42 and the digit display LED lamp group also displays a digit such as "8" and then blinks, which means that the tens of the height value is "8", that is, 80; similarly, when the single digit indication LED lamp 43 is switched to flash, the digital display LED lamp set displays a digit, for example, "5", and then flashes, which means that the single digit is "5", that is, 5; when the LED lamp 44 is switched to the decimal indication to flash, the digital display LED lamp group displays a number such as '3', and then flashes, which means that the decimal is '3', namely '0.3'; in summary, the maximum altitude of the altimeter flight is 800+80+5+ 0.3-885.3 m.
And after the switch is closed, the recorded height value is cleared, so that the device can be used repeatedly.
One corner of the PCB board 1 is provided with an inner concave corner 11, the switch 2 is attached to the edge of the inner concave corner, and a shifting piece of the switch 2 protrudes out of the inner concave corner 11.
