Technical field
The utility model relates to a kind of weighing-appliance, particularly relates to a kind of weighing mobile phone of high-precision wide detection range.
Background technology
In daily life, often run into the scene needing to weigh.As gone out shopping, worry is given short weight, and weighs after motion.Mobile phone to be gone out the equipment that must carry as people, by utilizing it to weigh, can solve the problem of weighing in daily life, overcoming user in the inconvenience needing to be inconvenient to carry in the scene of weighing weighing-appliance.
At present, what most of weighing mobile phone all adopted is hook weighting manner, and this weighting manner limitation is very large, when determinand can not be linked up with on hook, just has no idea to its detection of weighing.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of weighing mobile phone of high-precision wide detection range, is placed on by determinand on mobile phone, detect its weight by pressure sensor, and measuring range can do more, and measures convenient; By the design to pressure sensor installation site, available protecting mobile phone screen and cell phone mainboard, avoid measured object to cause damage to mobile phone screen and cell phone mainboard.
The purpose of this utility model is achieved through the following technical solutions: a kind of weighing mobile phone of high-precision wide detection range, it comprises upper shell, mobile phone screen, cell phone mainboard and lower house from top to bottom successively, it also comprises one or more pressure sensor, described pressure sensor is fixedly connected between upper shell and lower house, upper shell or lower house are the supporting body of measured object, and supporting point is not arranged on mobile phone screen and cell phone mainboard, and on pressure sensor.
It also comprises filter and signal amplifier, and pressure sensor is connected with filter and signal amplifier successively, and signal amplifier is connected with the analog to digital converter on cell phone mainboard and CPU processor again successively.
Described pressure sensor comprises the different pressure sensor of the different range of at least two precision, and the symmetrical two ends being arranged on mobile phone.
Described pressure sensor comprises the pressure sensor that four bridge-types are electrically connected, and these four pressure sensors are distributed in the corner of mobile phone.
Described pressure sensor is resistance-strain type voltage sensor, comprises elastoresistance foil gauge.
Load-bearing reinforcement is also provided with between described pressure sensor and lower house.
Described upper shell and lower house are also provided with waterproof Anti-scratching diaphragm.
The beneficial effects of the utility model are:
1) the utility model is by the function of weighing of mobile phone, solves user in the problem needing to be inconvenient to carry in the scene of weighing weighing-appliance.
2) in the utility model, be placed on by determinand on mobile phone, detect its weight by pressure sensor, measuring range can do more, and measures convenient; By the design to pressure sensor installation site, available protecting mobile phone screen and cell phone mainboard, avoid measured object to cause damage to mobile phone screen and cell phone mainboard.
3) the utility model is by arranging multiple multiple pressure sensor, such that the certainty of measurement of weighing mobile phone is high, detection range is wide, have more practicality.
Accompanying drawing explanation
Fig. 1 is one of structure chart of the weighing mobile phone of the utility model high-precision wide detection range;
Fig. 2 is the structure chart two of the weighing mobile phone of the utility model high-precision wide detection range;
In figure, 1-upper shell, 2-lower house, 3-mobile phone screen, 4-pressure sensor.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail, but protection range of the present utility model is not limited to the following stated.
As shown in Figure 1; a kind of weighing mobile phone of high-precision wide detection range; it comprises upper shell 1, mobile phone screen 3, cell phone mainboard and lower house 2 from top to bottom successively; it also comprises one or more pressure sensor 4; described pressure sensor 4 is fixedly connected between upper shell 1 and lower house 2; upper shell 1 or lower house 2 are the supporting body of measured object; and supporting point is not arranged on mobile phone screen 3 and cell phone mainboard; and on pressure sensor 4; available protecting mobile phone screen and cell phone mainboard, avoid measured object to cause damage to mobile phone screen and cell phone mainboard.
