The electronic device provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
As shown in fig. 1, an embodiment of the present application discloses an electronic device, including: a battery rear cover 1; a metal antenna body 2 (dotted line part in the figure), wherein the metal antenna body 2 is embedded in the battery rear cover 1; the metal polar plate 3, the metal polar plate 3 locates on the surface of the battery back cover 1; the projection of the metal pole plate 3 on the plane where the metal antenna body 2 is located is a first projection, the first projection is at least partially overlapped with the metal antenna body 2, a first graph is formed in the overlapped area of the first projection and the metal antenna body 2, and the area of each unit length interval of the first graph in the first direction is unequal; and the detection device is connected with the metal polar plate 3 and is used for detecting the capacitance value between the metal antenna body 2 and the metal polar plate 3.
The battery back cover 1 is a non-conductive battery back cover, and the material of the battery back cover 1 may be plastic, glass, or other non-conductive material.
Here, the metal plate 3 may be disposed on a surface of the battery back cover, for example, attached to an inner surface of the battery back cover 1, or may be disposed on another surface of the battery back cover, which is not limited in the embodiment of the present application. Because the metal antenna body 2 is embedded in the battery rear cover 1, the metal polar plate 3 is arranged on the inner surface of the battery rear cover 1. The metal antenna body 2 and the metal pole plate 3 form a gap with a preset distance.
Here, the inner surface of the battery back cover 1 specifically refers to a side of the battery back cover 1 close to the main board of the electronic device.
It should be noted that the metal antenna body 2 is parallel to the metal plate 3 and spaced by a predetermined distance, a capacitor is formed between the metal antenna body 2 and the metal plate 3, the metal antenna body 2 serves as one plate of the capacitor, and the metal plate 3 serves as the other plate of the capacitor.
Here, the projection of the metal pole plate 3 on the plane where the metal antenna body 2 is located is a first projection, the first projection is at least partially overlapped with the metal antenna body 2, a first pattern is formed in an overlapped area of the first projection and the metal antenna body 2, and the area of the first pattern in each unit length interval in the first direction is unequal, so that when the metal antenna body 2 is cracked or broken in the production process of the electronic device, the crack or the break of the metal antenna body 2 can be detected according to the change of the capacitance value between the metal pole plate 3 and the metal antenna body 2.
In one example, as shown in fig. 2, the overlapping region of the metal plate 3 and the metal antenna body 2 forms a first pattern, the first pattern is a triangle, and the area of the first pattern in each unit length section in the first direction is not equal, wherein the first direction is the length direction of the metal antenna body 2, the unit length section is any one of N length sections obtained by equally dividing the length of the metal antenna body 2 by N, and N is a positive integer greater than or equal to 2.
Of course, the above is only an example, and the first direction may also be the width direction of the metal antenna body 2; the length direction or the width direction of the battery back cover 1 may be also the length direction or the width direction of the metal plate 3, which is not limited herein.
As an optional implementation manner, the electronic device further includes:
a processor (not shown) connected to the detection means.
Wherein the processor is configured to obtain the capacitance value; obtaining a first superposition area according to the capacitance value; determining a first overlapping area corresponding to the first overlapping area according to the corresponding relation between the overlapping areas and the overlapping areas; and determining whether the metal antenna body has a failure part or not according to the first overlapping area.
Here, the capacitance value is a capacitance value between the metal antenna body 2 and the metal plate 3 detected by the detection device.
When the metal antenna body 2 of the electronic device is normal, the overlapping area of the metal plate 3 and the metal antenna body 2 is the largest. When a fracture occurs at a certain position, the fracture is corresponding to a specific overlapping area, namely the overlapping areas are different, the corresponding fracture positions are different, and according to a capacitance calculation formula: when C is k × S × h, it is possible to accurately determine at which position the metal antenna body 2 is broken. Wherein C represents a capacitance value between the metal antenna body 2 and the metal pole plate 3; k represents an electrostatic force constant; s represents a coincidence area between the metal antenna body 2 and the metal plate 3; represents a dielectric constant; h represents the separation distance between the metal antenna body 2 and the metal plate 3.
Optionally, as shown in fig. 1, a first side of the metal plate 3 is flush with a second side of the metal antenna body 2, and a length of the first side is equal to a length of the second side.
That is, the first side of the metal plate 3 is consistent with the width of the metal antenna body 2. If the length of the metal antenna body 2 is L and the width thereof is W, the first side of the metal plate 3 is W.
Optionally, the detection device is connected to the metal plate 3 through a conductive connection assembly.
In an optional implementation, the conductive connection assembly includes: conductive contact 4 and metal spring (not shown); the conductive contact piece 4 is connected with the metal polar plate 3; the metal elastic sheet is respectively connected with the metal polar plate 3 and the detection device.
It should be noted that, the number of the conductive contact pieces 4 is plural, and the surface is plated with gold and arranged like a finger.
Optionally, the detection device is a capacitive sensor.
In one example, the capacitive sensor may be a SAR-reduction sensor function block in a SAR (Specific Absorption Rate) sensor; the metal plate 3 is a metal antenna plate in the SAR sensor. It should be noted that the SAR reduction sensor function module is disposed on a main board of the electronic device. That is to say, the capacitance detection method of the SAR reduction sensor can be directly utilized, and according to the capacitance change between the metal antenna body 2 and the metal pole plate 3, whether the metal antenna body 2 embedded in the battery rear cover 1 is normal or abnormal can be detected, so that the risk point is avoided in advance, the manufacturing cost is saved, and the quality problem is solved from the material end.
Alternatively, in order to facilitate detection of the capacitance value, the area of the first pattern in the adjacent unit length section in the first direction is linearly increased.
In one example, as shown in fig. 2, the metal antenna body 2 is a rectangular antenna body, and has a length L and a width W; the average division of L is N6, the corresponding overlap area S1 WL/12, S2 3WL/12, S3 5WL/12, S4 7WL/12, S5 9WL/12, and S6 11 WL/12.
As can be seen from the above example, the areas in the adjacent unit length sections of the first pattern (specifically, the triangle in this example) are, for example, S2 is greater than S1, and S1 and S2 are isodyne, S3 is greater than S2, and S2 and S3 are isodyne, that is, the areas in the adjacent unit length sections of the first pattern increase linearly. Therefore, the overlapping area is determined through the detected capacitance value, and then the corresponding part on the metal antenna body can be determined according to the overlapping area.
In the electronic device of the embodiment of the application, the metal antenna body is embedded in the rear cover of the battery; the metal polar plate is arranged on the surface of the battery rear cover; the projection of the metal pole plate on the plane of the metal antenna body is a first projection, the first projection is at least partially overlapped with the metal antenna body, a first graph is formed in the overlapped area of the first projection and the metal antenna body, and the area of each unit length interval of the first graph in the first direction is unequal; the detection device is connected with the metal pole plate and used for detecting the capacitance value between the metal antenna body and the metal pole plate, so that whether the metal antenna body embedded in the battery rear cover is normal or not and the abnormal position can be detected according to the change of the capacitance value between the metal antenna body and the metal pole plate, the risk of poor hardware quality after an electronic device finished product caused by the restriction of the antenna design in the electronic device is avoided in advance, and the finished product quality of the electronic device is improved.

Here, the existence of the failed part in the metal antenna body indicates that a crack and/or a slit exists in the hardware of the metal antenna body, and specifically, where the failed part appears can be determined by the position of the first overlapping area.
Here, the information of the failure part is displayed, and the purpose is to notify the user that the metal antenna body is abnormal, so that the user can find out problems in time and repair or replace the metal antenna body.
