Detailed Description

It should be noted that, in the present application, technical features in examples and embodiments may be combined with each other without conflict, and the detailed description in the specific embodiment should be understood as an explanation of the gist of the present application and should not be construed as an improper limitation to the present application.

The directional terms used in the description of the present application are used for convenience in describing the present application and for simplicity in description, and do not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the present application.

Before describing the embodiments of the present application, the principle of calibration of the proximity switch will be described. Referring to fig. 3, when the proximity switch 31 of the terminal device 3 is calibrated, the key 311 of the proximity switch 31 is toggled to move to different positions, and the sensing element 312 in the proximity switch 31 records corresponding position information of the key 311 corresponding to different states of the terminal device 3, that is, the calibration of the terminal device 3 is primarily completed. When the user uses the terminal device, the user dials the key 311 to reach different position intervals, which is used as a basis for switching the state of the terminal device 3. For example, three different position intervals are reached by toggling the key 311, so that the terminal device 3 is switched in three different states.

Before describing the embodiments of the present application, it is necessary to analyze the defects of the calibration operation of the proximity switch in the prior art, and obtain the technical solution of the embodiments of the present application through reasonable analysis.

In the prior art, in the process of calibrating the proximity switch 31 of the terminal device 3, for example, a hall switch, an operator usually manually dials the key 311 of the hall switch to record different position information of the key 311, and the different position information is used as a basis for switching the state of the terminal device 3.

On the one hand, due to the structural characteristics of the key 311, in the process of dialing the key 311, the key 311 is easy to cause certain damage to the fingers of the operator, especially when in assembly line operation, the same operation needs to be performed on a plurality of terminal devices 3 repeatedly, and at this time, the damage to the fingers of the operator caused by calibration work is especially obvious.

On the other hand, taking hall switch calibration as an example, since the reading of the magnetic field strength of the hall element to the magnet 311 'is very sensitive to the relative position of the two, when the key 311 is dialed by a finger, a certain pressing action is applied to the key 311, that is, a certain acting force towards the hall element is generated to the key 311, so that the magnet 311' is easily too close to the hall element, and further the key 311 is not dialed in place, which causes the abnormal calibration value of the hall switch, even causes the result of the function failure of the hall switch.

The terminal device 3 may be various products such as a mobile phone, a tablet, or an electronic book reader, which have the proximity switch 31 and require calibration. The proximity switch 31 may be of any type, such as an eddy current type, a hall type, a capacitive type, or a photoelectric type, and the principle is that the state of an internal circuit of the proximity switch 31 is changed by the movement of the key 311, so as to control the terminal device 3 to switch the state. For example, the proximity switch 31 is a hall switch, and in this case, the button 311 includes a magnet 311', and a hall element, such as an IC element, is mounted on the terminal device 3 as the sensing element 312. The movement of the button 311 moves the magnet 311', so that the magnetic field around the hall element changes, and an induced current or an induced electromotive force is generated. The induced current or induced electromotive force generated by the hall elements corresponding to different positions of the key 311 is recorded as a signal for switching the state of the terminal device 3, that is, the calibration of the proximity switch 31 is completed.

It is understood that when the proximity switch 31 is an eddy current switch, the key 311 should include a conductive object, and the movement of the conductive object generates an eddy current inside the proximity switch 31 as a basis for switching the state of the terminal device 3. Similarly, when the proximity switch 31 is of other types, the key 311 should include corresponding materials capable of causing the state of the internal circuit of the proximity switch 31 to change, which will not be described herein again.

Referring to fig. 1, the calibration jig 1 includes a toggle portion 11 and a clamping portion 12. The toggle part 11 is used for applying force to toggle the key 311 of the proximity switch 31 to move, the clamping part 12 is provided with an accommodating cavity 121 for accommodating the key 311, and the clamping part 12 is connected with the toggle part 11 and used for clamping the key 311.

In the process of calibrating the proximity switch 31 of the terminal device 3, the fixed jig 2 is used for limiting 6 degrees of freedom of the terminal device 3, and shaking or displacement of the terminal device is avoided. The calibration jig 1 abuts against the key 311 of the proximity switch 31 through the clamping portion 12, and the force is applied to the toggle portion 11 to drive the calibration jig 1 to move, so as to drive the key 311 to move, thereby completing the calibration work of the proximity switch 31.

It should be understood that the form of the fixing jig 2 is not limited to the groove shape shown in fig. 2 and 3, and may be a claw type or a snap type, which can limit 6 degrees of freedom of the terminal device 3, so as to ensure that the terminal device 3 does not shift or move when the calibration jig 1 is operated.

Preferably, the calibration jig 1 is made of a hard plastic material, so that the weight of the calibration jig 1 can be reduced, the calibration jig 1 is soft, the key 311 is protected from being scratched, manual operation of an operator is facilitated, and the principle of man-machine engineering is better met.

The calibration jig 1 of the proximity switch 31 provided by the embodiment of the application has the advantages that the toggle part 11 and the clamping part 12 are arranged, the movement of the key 311 can be realized by manually operating the toggle part 11 or operating other power, the finger does not need to be directly contacted with the key 311, the damage of the key 311 to the finger is avoided, and the calibration jig 1 is simple in structure and convenient and fast to operate.

In an embodiment, referring to fig. 1 to 3, the clamping portion 12 of the calibration fixture 1 provided by the present application includes clamping arms 122 formed at two ends of the accommodating cavity 121 along the moving direction of the key 311, and each clamping arm 122 is connected to the toggle portion 11. In the calibration work, the two ends of the key 311 are clamped by the clamping arms 122 to drive the key 311 to move, the calibration jig 1 with the structure is simpler in structure, can be rapidly installed on the key 311 and also can be rapidly detached, and the convenience in operation is further improved.

Preferably, the clamping arm 122 is in surface contact with the key 311, and the contact area is as large as possible, so that the reliability of the calibration jig 1 for transmitting power to the key 311 can be improved, and the smoothness of the movement of the key 311 can be improved.

Further, in an embodiment, referring to fig. 1 to 3, the toggle portion 11 of the calibration fixture 1 provided by the present application includes a boss 111 and a toggle body 112. The boss 111 is used for applying force so that the toggle button 311 moves, two ends of the toggle body 112 are respectively connected with the boss 111 and the clamping part 12, and a positioning area 113 is formed between the boss 111 and the toggle body 112.

Through setting up boss 111, improved manual operation's convenience, can also set up the circular arc chamfer at boss 111's edges and corners department, prevent the injury that the edges and corners caused to the operator finger. When the power part 4 is used for operation, the bosses 111 and the positioning areas 113 improve the clamping and positioning precision of the power part 4 on the calibration jig 1, and improve the working stability and reliability of the calibration jig 1.

In an embodiment, referring to fig. 2 and fig. 3, the accommodating cavity 121 of the calibration fixture 1 provided by the present application includes an accommodating area 1211 and an avoiding area 1212. The receiving area 1211 is used for receiving the key 311, and the size of the receiving area 1211 matches with the size of the key 311 along the moving direction of the key 311. Specifically, the size of the receiving area 1211 may be slightly larger than the size of the key 311, or may be the same as the size of the key 311, so as to avoid the inaccuracy of controlling the displacement of the key 311 due to the excessive gap between the two.

The space-avoiding region 1212 is in communication with the accommodating region 1211 and is used for spacing the key 311 from the dial portion 11. The existence of the clearance 1212 can prevent the toggle body 112 of the calibration fixture 1 from contacting the key 311, and effectively prevent the calibration fixture 1 from generating an acting force on the key 311 in a direction toward the key 311 along the calibration fixture 1, thereby preventing the magnet 311' from being too close to the hall element, which causes the proximity switch 31 to fail.

In an embodiment, referring to fig. 1 to fig. 3, the calibration fixture 1 further includes a guiding portion 13, wherein the guiding portion 13 is connected to the clamping portion 12 and is used for guiding when the toggle button 311 moves.

Alternatively, the guide portions 13 may be provided on both the grip arms 122 of the grip portion 12 at both ends in the moving direction of the key 311, or the guide portions 13 may be provided only on the grip arm 122 at one end thereof. Specifically, the guiding portion 13 may be a two-sheet structure, and the two-sheet structure is distributed on two sides of the clamping arm 122, and when the calibration jig 1 moves, the two-sheet structure slides on the terminal device 3, so as to prevent the key 311 from shifting during the moving process. The guiding portion 13 may also be a roller structure, and when the calibration fixture 1 moves, the roller rolls on the terminal device 3, so as to still prevent the key 311 from shifting during the movement.
