Abstract
The utility model discloses a kind of mobile phone multipoint pressure test structure, the structure includes：The pressure contact block being linked in sequence, pressure sensor, micrometer and stepper motor, the micrometer is rotatably connected on the output shaft of stepper motor, and can up and down be stretched with the rotation of stepper motor, the other end of the micrometer is connected with pressure sensor, the pressure contact block is arranged on the tail end of pressure sensor, the pressure sensor is electrically connected with stepper motor, the pressure contact block applies pressure to mobile phone to be detected, and pressure contact block pressure applied scope is judged by the pressure sensor, stepper motor rotates and adjusts the length of micrometer to change the pressure that pressure sensor is received if not in the pressure limit.It is static test mode that the utility model, which solves existing mobile phone pressure test, it is impossible to the size of the rising dynamic adjustment pressure of technical indicator, the poor technical problem of test accuracy, with can dynamic regulation test pressure, the features such as stable testing.
Description
【Technical field】
The utility model is related to mobile phone test field, more particularly to a kind of mobile phone multipoint pressure test structure.
【Background technology】
With the continuous progress of science and technology, the update of mobile phone productses is more and more faster, at present, intelligent touch-screen hand
Progressively substitution conventional keys mobile phone turns into the Mobile Phone Consumption product of main flow to machine, however, smart mobile phone is because screen is larger, machine
Body is relatively thin, so crash resistance is poor, causes its service life shorter, therefore, the drop resistant performance of handset shell it is whether qualified, it is necessary to
Carrying out strength test to it can just learn, mobile phone needs to choose a point in entire surface in manufacturing process or multiple points are carried out
Pressing carries out pressure test simultaneously, and the traditional pressure test point from one o'clock to four, uses spring and pressure is passed
The combination of sensor, static test mode, but with the rising of technical indicator, it is desirable to multiple spot is tested simultaneously, traditional test
Method accuracy and continuity are poor.
【The content of the invention】
In summary, the main purpose of the utility model is the test in order to solve existing mobile phone pressure test for static state
Mode, it is impossible to the size of the rising dynamic adjustment pressure of technical indicator, the poor technical problem of test accuracy, and provide
A kind of mobile phone multipoint pressure test structure.
In order to solve the above-mentioned technical problem, the utility model provides a kind of mobile phone multipoint pressure test structure, the structure
Including：Pressure contact block, pressure sensor, micrometer and the stepper motor being linked in sequence, the micrometer are rotatably connected
On the output shaft of stepper motor, and can up and down it be stretched with the rotation of stepper motor, the other end of the micrometer is connected with pressure
Force snesor, the pressure contact block is arranged on the tail end of pressure sensor, and the pressure sensor is electrically connected with stepper motor,
The pressure contact block applies pressure to mobile phone to be detected, and judges the pressure that pressure contact block is applied by the pressure sensor
Power scope, stepper motor rotates and adjusts the length of micrometer to change pressure sensor receipts if not in the pressure limit
The pressure arrived.
Rectangular Spring is provided with the pressure sensor and in pressure contact block.
The outside of the pressure contact block, pressure sensor and micrometer is also arranged with protective cover.
Beneficial effect produced by the utility model is：Compared with existing technical scheme, the utility model can be dynamic
The pressure of test is adjusted, so as to reach the effect of steady testing, without increasing and the original such as connection loosing with testing time
The pressure change thus produced causes test errors.Further, since adding the micrometer and miniature stepping electricity of adjustable length
Machine, therefore the signal that can be provided by pressure sensor judges whether pressure is qualified, if not within the scope of we require,
Micrometer length can be adjusted by rotary electric machine to reach that change pressure sensor receives pressure come required for adjusting in time
Pressure.
【Brief description of the drawings】
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of the present utility model without protective cover；
【Embodiment】
The following example is explained further and supplemented to of the present utility model, and any limit will not be constituted to the utility model
System.
As shown in Fig. 1~Fig. 2, a kind of mobile phone multipoint pressure test structure of the present utility model includes：The pressure being linked in sequence
Power contact block 1, pressure sensor 2, micrometer 3 and stepper motor 4.Inventive point of the present utility model is, in traditional pressure
Micrometer 3 and stepper motor 4 are added in test structure, the micrometer 3 is rotatably connected in the output shaft of stepper motor 4
On, and can up and down be stretched with the rotation of stepper motor, the other end of the micrometer 3 is connected with pressure sensor 2, the pressure
Power contact block 1 is arranged on the tail end of pressure sensor 2, and the pressure sensor 2 is electrically connected with stepper motor 4, and the pressure connects
Contact block 1 applies pressure to mobile phone to be detected, and judges the pressure applied scope of pressure contact block 2 by the pressure sensor 2,
Stepper motor 4 rotates and adjusts what the length of micrometer 3 was received to change pressure sensor if not in the pressure limit
Pressure, the pressure of our needs is adjusted with this.
As shown in Fig. 2 further, Rectangular Spring 5 is provided with the pressure sensor 2 and in pressure contact block 1.
Such as Fig. 1, further, the outside of the pressure contact block 1, pressure sensor 2 and micrometer 3 is also arranged with protection
Cover 6.
By above-mentioned technical proposal compared with scheme before, the pressure that this mode can be tested with dynamic regulation, so that
The effect of steady testing, rather than increasing with testing time are reached, the pressure change produced due to reasons such as connection loosings
Cause test errors.
Although being disclosed by above example to the utility model, scope of the present utility model is not limited to
In this, under conditions of conceiving without departing from the utility model, it is similar that each component of the above can be understood with art personnel
Or equivalent element is replaced.
