The electronic device provided by the embodiment of the application is described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.
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), the metal antenna body 2 is embedded in the battery rear cover 1; the metal polar plate 3 is arranged on the surface of the battery rear cover 1; the projection of the metal polar 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 an overlapped area of the first projection and the metal antenna body 2, and the areas of the first graph in each unit length interval in the first direction are 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 rear cover 1 is a non-conductive battery rear cover, and the material of the battery rear cover 1 may be a non-conductive material such as plastic or glass.
The metal electrode plate 3 may be disposed on the surface of the battery rear cover, for example, attached to the inner surface of the battery rear cover 1, or may be disposed on other surfaces of the battery rear cover, which is not limited in the embodiment of the present application. Since the metal antenna body 2 is embedded in the battery rear cover 1, the metal electrode plate 3 is provided on the inner surface of the battery rear cover 1. The metal antenna body 2 and the metal polar plate 3 form a space, and the space is preset.
Here, the inner surface of the battery back cover 1 specifically refers to a surface of the battery back cover 1 close to the main board of the electronic device.
The metal antenna body 2 and the metal electrode plate 3 are parallel and spaced by a preset distance, a capacitor is formed between the metal antenna body 2 and the metal electrode plate 3, the metal antenna body 2 is used as one electrode plate of the capacitor, and the metal electrode plate 3 is used as the other electrode plate of the capacitor.
Here, the projection of the metal electrode 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, the overlapped area of the first projection and the metal antenna body 2 forms a first pattern, and the areas of the first pattern in each unit length interval in the first direction are different.
In an example, as shown in fig. 2, the overlapping area of the metal electrode plate 3 and the metal antenna body 2 forms a first pattern, the first pattern is a triangle, and the area of each unit length section in the first direction is unequal, where 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 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 merely an example, and the first direction may be the width direction of the metal antenna body 2; the length direction or width direction of the battery rear cover 1, or the length direction or width direction of the metal electrode plate 3 may be used, and is not particularly limited.
As an alternative implementation, the electronic device further includes:
a processor (not shown) coupled to the detection device.
The processor is used for acquiring 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 determining whether a failure part exists in the metal antenna body 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 electrode plate 3 and the metal antenna body 2 is the largest. When a fracture occurs at a certain position, a specific overlapping area is corresponding, namely, the overlapping areas are different, the corresponding fracture positions are different, and according to a capacitance calculation formula: c=k×s×epsilon/h, it is possible to accurately determine at which position the metal antenna body 2 breaks. Wherein, C represents the capacitance value between the metal antenna body 2 and the metal polar plate 3; k represents an electrostatic force constant; s represents the superposition area between the metal antenna body 2 and the metal polar plate 3; epsilon represents the dielectric constant; h represents the distance between the metal antenna body 2 and the metal plate 3.
Optionally, as shown in fig. 1, the first side of the metal pole plate 3 is flush with the second side of the metal antenna body 2, and the length of the first side is equal to the 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 is W, the first side of the metal plate 3 is W.
Optionally, the detection device is connected with the metal polar plate 3 through a conductive connection component.
In an alternative implementation, the conductive connection assembly includes: conductive contacts 4 and metal spring plates (not shown); wherein the conductive contact 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.
The number of conductive contacts 4 is plural, and the surface of the conductive contacts is arranged like a finger.
Optionally, the detection device is a capacitive sensor.
In an example, the capacitive sensor may be a reduced electromagnetic wave absorption ratio (Specific Absorption Rate, SAR) sensor function module in a reduced SAR sensor; the metal plate 3 is a metal antenna plate in a down SAR sensor. It should be noted that the SAR reduction sensor functional module is disposed on a motherboard of the electronic device. That is, the capacitance detection method of the SAR sensor can be directly utilized, and according to the capacitance change between the metal antenna body 2 and the metal electrode plate 3, whether the metal antenna body 2 embedded in the battery rear cover 1 is normal or abnormal can be detected, so that risk points can be avoided in advance, manufacturing cost can be saved, and quality problems can be solved from a material end.
Optionally, in order to facilitate detection of the capacitance value, the area of the first pattern in adjacent unit length intervals in the first direction increases linearly.
In an 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 of L was divided into n=6 parts, corresponding to overlapping areas s1=wl/72, s2=3 WL/72, s3=5 WL/72, s4=7 WL/71, s5=9 WL/72, s6=11 WL/72.
As can be seen from the above examples, the area in the adjacent unit length sections of the first pattern (specifically, triangle in this example) is larger than S1, S1 and S2 are equal difference, S3 is larger than S2, and S2 and S3 are equal difference, i.e., the area in the adjacent unit length sections of the first pattern increases linearly. In this way, the overlapping area is determined by 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 polar 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 an overlapped area of the first projection and the metal antenna body, and the areas of the first graph in each unit length interval in the first direction are unequal; the detection device is connected with the metal polar plate and is used for detecting the capacitance value between the metal antenna body and the metal polar 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 polar plate, the risk that the hardware quality is poor after the finished product of the electronic equipment is caused by the restriction on the antenna design in the electronic equipment is avoided in advance, and the quality of the finished product of the electronic equipment is improved.
