Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 to 9, an embodiment of the present invention provides a terminal device, including a housing (not shown) and a telescopic module 10 capable of extending out of or retracting into the housing, where the telescopic module 10 includes a support 11 and a functional device 12 disposed on the support 11, and the functional device 12 may be a camera, an infrared sensor, or the like; and the terminal device may further include a driving mechanism (not shown) for driving the telescopic module 10 to extend out of or retract into the housing, the driving mechanism is in driving connection with the telescopic module 10, and the telescopic module 10 is driven to make a stroke motion so as to switch between an extending state of extending out of the housing and a retracting state of shrinking the housing.
Wherein, terminal equipment still includes:
a detection terminal group 20 disposed on the expansion module 10;
an inductance coil assembly 30 disposed in the telescopic channel of the detection terminal group 20;
and a detection module (not shown) electrically connected to the inductance coil assembly 30 for detecting an inductance change of the inductance coil assembly 30 and determining a telescopic distance of the telescopic module 10 according to the inductance change.
In the present embodiment, since the detecting terminal set 20 is disposed on the telescopic module 1, the detecting terminal set 20 can move along with the telescopic module 10, that is, the telescopic strokes of the detecting terminal set 20 and the telescopic module 10 are the same. Thus, the telescopic distance of the telescopic module 10 can be determined by detecting the telescopic distance of the detection terminal group 20.
By arranging the inductance coil assembly 30 in the telescopic channel of the detection terminal set 20, the telescopic channel is a movement space occupied by the detection terminal set 20 in the movement process along with the telescopic module 10, and the inductance coil assembly 30 can be arranged opposite to the detection terminal set 20. Thus, during the telescopic movement of the detecting terminal set 20 with the telescopic module 10, there is an overlapping area between the detecting terminal set 20 and the inductance coil assembly 30. And since the relative positions of the detection terminal set 20 and the inductance coil assembly 30 are different, the inductance values of the inductance coil assembly 30 are also different; therefore, the inductance variation of the inductance coil assembly 30 can be detected by the detection module, and the relative position between the detection terminal set 20 and the inductance coil assembly 30 can be determined according to the inductance variation, so as to determine the telescopic distance of the telescopic module 10 (the detection terminal set 20). Through the inductance change condition that detects inductance coil assembly 30, can carry out real-time detection to the flexible distance of flexible module 10 to the flexible distance that obtains flexible module 10 that can be accurate, the effectual problem that has solved the calculation of the flexible distance of flexible module 10 among the prior art and has had the accuracy poor.
The inductor assembly 30 includes a substrate (not shown) and an inductor assembly disposed on the substrate, and the inductor assembly may be disposed on the substrate by etching or by pasting and winding. The substrate may be a circuit board, or a plate structure for fixing, and is preferably a circuit board.
In the process of stretching and retracting the detection terminal set 20, a projection track of the detection terminal set 20 on the substrate forms a projection area, the projection area is an overlapping coverage area existing between the detection terminal set 20 and the substrate in the process of stretching and retracting, and the inductance coil sets are at least distributed in the projection area. In this way, in the process of the telescopic movement of the detection terminal group 20, the inductance of the inductance coil group will change continuously, so that the relative position between the detection terminal group 20 and the inductance coil group can be determined according to the inductance that changes continuously, and the telescopic distance between the detection terminal group 20 and the telescopic module 10 can be further determined.
The inductance detection principle according to the embodiment of the invention comprises the following steps: when a target object (such as metal) approaches the inductance coil, the resonance frequency of the inductance coil is changed, the change of the frequency is detected through a detection chip (namely a detection module), the change condition of the inductance coil can be calculated according to the change condition of the frequency, and the position relation or the relative position of the target object and the inductance coil is further determined according to the inductance change condition of the inductance coil.
The following describes in detail embodiments of the present invention:
as shown in fig. 1, the inductance coil assembly may be directly disposed on the substrate (circuit board), and the coil density of the inductance coil assembly may gradually become sparse along the extension and retraction direction of the detection terminal assembly 20 (i.e., the direction from the contraction state of the extension and retraction module to the extension state of the extension and retraction module), and the detection terminal assembly 20 disposed on the support 12 is suspended above the inductance coil assembly. Thus, when the detecting terminal set 20 (i.e. the telescopic module 10) is located at different stroke positions, the number of coils covered by the detecting terminal set 20 is different, and the inductance detected by the detecting module is also different, so that the relative positions of the detecting terminal set 20 and the inductance coil set can be determined according to the detected inductance change condition, and the telescopic distance between the detecting terminal set 20 and the telescopic module 10 can be determined. The coil density of the inductance coil set may also gradually become dense along the expansion and contraction direction of the detection terminal set 20 (i.e., the direction from the contraction state of the expansion module to the extension state of the expansion module), and the distribution manner of the coil density of the inductance coil set in this embodiment is not particularly limited, as long as the number of coils covered by the detection terminal set 20 is different when the detection terminal set 20 is at different stroke positions.
It can be assumed that the detection terminal set 20 is located in the densest area of the inductor coil set when the detection terminal set 20 is at the zero point of the contracted state, so that the inductance of the inductor coil set changes as the detection terminal set 20 moves in the contraction direction as shown in fig. 2.
However, since a single inductance coil is easily interfered, in order to improve the detection accuracy and the detection anti-interference capability of the inductance change condition, a detection mode combining two inductance coils or a plurality of inductance coils can be used. The example that the inductor group includes the first inductor 31 and the second inductor is given as an example.
As shown in fig. 3, the density direction of the coil density of the first inductor coil 31 is opposite to the density direction of the coil density of the second inductor coil 32, and the first inductor coil 31 and the second inductor coil 32 are arranged in parallel along the expansion and contraction direction of the detection terminal group 20. Fig. 4 is a schematic diagram showing changes in inductance corresponding to the inductor group in the present embodiment.
As shown in fig. 5, the density direction of the coil density of the first inductor coil 31 is opposite to the density direction of the coil density of the second inductor coil 32, and the first inductor coil 31 and the second inductor coil 32 are arranged in series along the expansion and contraction direction of the detection terminal group 20; the detection terminal set 20 includes a first terminal 21 disposed opposite to the first inductor 31 and a second terminal 22 disposed opposite to the second inductor 32. Fig. 6 is a schematic diagram showing changes in inductance corresponding to the inductor group in the present embodiment.
As shown in fig. 7, the inductance coil set may be an inductance coil with a uniform coil density distribution, the detection terminal set 20 may be a metal sheet, and when the stroke position of the detection terminal set 20 changes, the overlapping area between the detection terminal set 20 and the inductance coil set also changes, so that the inductance of the inductance coil set detected by the detection module also changes, and the telescopic distance between the detection terminal set 20 and the telescopic module 10 is determined according to the inductance change. Fig. 8 is a schematic diagram showing changes in inductance corresponding to the inductor group in the present embodiment. In addition, in order to improve the detection accuracy and the detection anti-interference capability of the inductance change condition, two or more coils can be arranged to be combined for detection.
As shown in fig. 9, the inductor set may include at least two inductors, and the at least two inductors are spaced apart along the telescoping direction of the detecting terminal set 20, so that the telescoping distance of the telescoping module 10 can be detected step by step. As shown in fig. 9, in the present embodiment, the inductor group includes 6 inductors, which are L1, L2, L3, L4, L5, and L6 in sequence, the detection terminal group 20 is set to be one metal sheet (detection terminal), and when the detection terminal group 20 covers a certain inductor and detects that the inductance of the inductor is greater than a preset threshold value, the induction result corresponding to the inductor is set to be 1, otherwise, the induction result is set to be 0. And when the induction result of two induction coils is 1, the interference is determined to exist, and the stroke position (telescopic distance) of the telescopic module can be judged in an auxiliary manner by matching with the induction coil state of the last position. The corresponding relationship between the sensing result and the stroke position (telescopic distance) is shown in table 1:
| l1 value | L2 value | L3 value | L4 value | L5 value | L6 value | Position of |
| 1 | 0 | 0 | 0 | 0 | 0 | 1 |
| 0 | 1 | 0 | 0 | 0 | 0 | 2 |
| 0 | 0 | 1 | 0 | 0 | 0 | 3 |
| 0 | 0 | 0 | 1 | 0 | 0 | 4 |
| 0 | 0 | 0 | 0 | 1 | 0 | 5 |
| 0 | 0 | 0 | 0 | 0 | 1 | 6 |
TABLE 1
In order to enhance the anti-interference capability, the detecting terminal set 20 may include two or more metal sheets (detecting terminals), and when the detecting terminal set 20 includes two detecting terminals, the corresponding relationship between the sensing result and the stroke position (telescopic distance) is shown in table 2:
| l1 value | L2 value | L3 value | L4 value | L5 value | L6 value | Position of |
| 1 | 1 | 0 | 0 | 0 | 0 | 1 |
| 0 | 1 | 1 | 0 | 0 | 0 | 2 |
| 0 | 0 | 1 | 1 | 0 | 0 | 3 |
| 0 | 0 | 0 | 1 | 1 | 0 | 4 |
| 0 | 0 | 0 | 0 | 1 | 1 | 5 |

The number of the detection terminals can be increased to further increase the reliability of detection, and the positions of the detection terminals can also be arranged non-adjacently.
Like this, through the inductance change condition that detects inductance coil assembly 30, can carry out real-time detection to the flexible distance of flexible module 10 to the flexible distance that obtains flexible module 10 that can be accurate, there is the poor problem of accuracy in the effectual calculation of the flexible distance of having solved flexible module among the prior art.

Like this through the inductance change condition that detects inductance coil assembly, can carry out real-time detection to the flexible distance of flexible module to the flexible distance that obtains flexible module that can be accurate, the effectual problem that has solved the calculation of the flexible distance of flexible module among the prior art and has had the accuracy poor.

Then, the telescopic distance of the telescopic module corresponding to the inductance change condition can be searched from the preset second corresponding relation, so that the telescopic distance of the telescopic module of the terminal equipment is determined.
