[0034] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.
[0035] See also Figure 1 As shown, Figure 1The present invention provides an electronic device 1, which may be a mobile electronic device such as a mobile phone, a tablet, or a laptop computer. The present invention takes the mobile phone as an example for explanation, which should not be construed as a limitation on the electronic device 1.
[0036] The electronic device 1 includes an antenna assembly, which is a medium for the electronic device 1 to communicate with the outside world. In the prior art, the antenna assembly is usually designed by stamping a metal sheet, and the shape of the metal sheet is stamped out by a mold. However, this method requires the design of a dedicated mold and has many process steps.
[0037] In order to reduce the occurrence of the above situation, the antenna assembly is improved in the embodiment of the present application, which will be explained below with reference to the accompanying drawings.
[0038] Please combine Figure 1 Also see Figure 2 As shown, Figure 2 A first structural schematic diagram of an antenna assembly provided in an embodiment of the present application. The antenna assembly 100 includes a circuit board 110 and an antenna body 120. The circuit board 110 is used to provide a basis for electrical connection for electrical components. The circuit board 110 has a plurality of metal solder joints (not shown in the figure) for connecting electrical components. Exemplarily, the circuit board 110 has at least two slots 112. The slots 112 may be grooves or through holes. The specific configuration may be as required and is not specifically limited here. Among them, the slots 112 or the side walls surrounding the slots 112 are covered with metal solder joints to facilitate the connection of electrical components.
[0039] The antenna body 120 is the main component of the antenna assembly 100. The antenna body 120 is integrated and bent. When manufacturing, it is only necessary to bend the material of a preset size and then connect it to the circuit board 110 to obtain the antenna assembly 100. The manufacturing process is simple and does not require a special mold, which can reduce costs. Among them, the antenna body 120 includes a first feeding part 122, a grounding part 124 and at least one radiating arm 126. The first feeding part 122 is also the feeding point of the signal, and the grounding part 124 refers to the component that grounds the antenna body 120 so that the antenna body 120 can form an electrical loop. The first feeding part 122 and the grounding part 124 are respectively penetrated in at least two slots 112. On the one hand, an electrical loop can be formed, and on the other hand, the first feeding part 122 and the grounding part 124 can also be used to fix at least one radiating arm 126.
[0040] In the antenna assembly 100 provided in the embodiment of the present application, the antenna body 120 is designed to be an integrated and bent structure, and is fixed in the slot 112 of the circuit board 110 through the first feeding part 122 and the grounding part 124. There is no need to use a special mold to make the antenna body 120, and it can be achieved by simply bending it, which simplifies the manufacturing process of the antenna assembly 100 and can reduce costs.
[0041] Exemplarily, the material of the antenna body 120 is metal, the antenna body 120 is cylindrical, and the antenna body 120 is uniformly cylindrical in its extension direction, which can facilitate the preparation of the substrate of the antenna body 120. The diameter of the antenna body 120 ranges from 1 mm to 3 mm, such as a value in the range of 1.5 mm to 2 mm, which can achieve a certain strength and facilitate bending.
[0042] Exemplarily, in order to facilitate the fixing of the antenna body 120, the extension directions of two slots 112 in at least two slots 112 in the circuit board 110 intersect. It can be understood that the slot 112 can be in a long strip shape, and the extension direction of the slot 112 is also the length direction thereof. In addition, the two slots 112 are arranged at intervals, and the extension directions of the two slots 112 are arranged to intersect, such as the two slots 112 can be arranged vertically. Compared with the method of arranging the two slots in parallel, the reliability of fixing the antenna body 120 can be improved, thereby increasing the stability of the performance of the antenna body 120.
[0043] It should be noted that the antenna assembly 100 may have different numbers of radiation frequency bands, which is the frequency range in which the antenna can operate, such as the radiation frequency in the range of 1G to 300G. The antenna assembly 100 of the embodiment of the present application may have at least three structural components, which will be described below.
[0044] Please combine Figure 2 Also see Figure 3 and Figure 4 As shown, Figure 3 A schematic diagram of the structure of a circuit board provided in an embodiment of the present application, Figure 4 A schematic diagram of the structure of the antenna body provided in an embodiment of the present application. In the first mode, the antenna assembly 100 may have three different radiation frequency bands. Exemplarily, the antenna assembly 100 has a first direction X, a second direction Y and a third direction Z which are perpendicular to each other.
[0045] The first feeder 122 may be U-shaped to facilitate the arrangement and installation of the antenna body 120. For example, the first feeder 122 includes a first sub-segment 1220, a second sub-segment 1222, and a third sub-segment 1224. The second sub-segment 1222 is disposed in a slot 112, and the second sub-segment 1222 may extend along the second direction Y. The first sub-segment 1220 and the third sub-segment 1224 are disposed opposite to each other and both extend along the third direction Z. The first sub-segment 1220 is bent and connected to one end of the second sub-segment 1222, and the third sub-segment 1224 is bent and connected to the other end of the second sub-segment 1222.
[0046] Correspondingly, the grounding portion 124 may also be U-shaped. For example, the grounding portion 124 may include a fourth sub-segment 1240, a fifth sub-segment 1242, and a sixth sub-segment 1244. The fifth sub-segment 1242 is disposed in another slot 112, and the fifth sub-segment 1242 may extend along the first direction X. The fourth sub-segment 1240 and the sixth sub-segment 1244 are disposed opposite to each other and both extend along the third direction Z. The fourth sub-segment 1240 is bent and connected to one end of the fifth sub-segment 1242, and the sixth sub-segment 1244 is bent and connected to the other end of the fifth sub-segment 1242.
[0047] Exemplarily, the distance between the second sub-segment 1222 and the fifth sub-segment 1242 ranges from 9 mm to 16 mm, such as a value in the range of 10 mm to 15 mm, to meet the requirements of radiation arms in different frequency bands.
[0048] At least one radiating arm 126 includes a first radiating arm 1260, a second radiating arm 1262, and a third radiating arm 1264. The radiation frequency bands of the first radiating arm 1260, the second radiating arm 1262, and the third radiating arm 1264 are different.

[0049] Among them, the first radiation arm 1260, the second radiation arm 1262 and the third radiation arm 1264 are arranged to form a rectangular structure, and the first radiation arm 1260 and the third radiation arm 1264 are not connected. Compared with other extended shapes, the space occupied by the antenna body 120 can be saved.
[0050] Exemplarily, the first radiation arm 1260 includes a first sub-arm 1260a and a second sub-arm 1260b that are bent and connected, the first sub-arm 1260a is bent and connected to the first sub-segment 1220, and the first sub-arm 1260a extends along the second direction Y, and the second sub-arm 1260b extends along the first direction X. The bending angle of the first sub-arm 1260a and the second sub-arm 1260b can be 90°, so that the radiation requirement of the first radiation arm 1260 can be met, interference with other radiation arms can be avoided, and space can be saved. Exemplarily, the length of the first sub-arm 1260a is less than the length of the second sub-arm 1260b, so that the space occupied by the antenna body 120 along the second direction Y can be saved.
[0051] Exemplarily, the second radiation arm 1262 includes a third sub-arm 1262a and a fourth sub-arm 1262b that are connected in a bending manner. The third sub-arm 1262a is connected in a bending manner to the third sub-segment 1224, and the third sub-arm 1262a extends along the second direction Y. The fourth sub-arm 1262b extends along the first direction X and is connected in a bending manner to the fourth sub-segment 1240. The bending angle of the third sub-arm 1262a and the fourth sub-arm 1262b can be 90°, so that the working requirements of the second radiation arm 1262 can be met, interference with other radiation arms can be avoided, and space can be saved. Among them, the length of the third sub-arm 1262a is less than the length of the fourth sub-arm 1262b, so that the space occupied by the antenna body 120 along the second direction Y can be saved.
[0052] Exemplarily, the third radiating arm 1264 includes a fifth sub-arm 1264a, a sixth sub-arm 1264b, a seventh sub-arm 1264c, an eighth sub-arm 1264d and a ninth sub-arm 1264e which are bent and connected in sequence. The fifth sub-arm 1264a is bent and connected to the sixth sub-segment 1244 and extends along the first direction X. The sixth sub-arm 1264b extends along the second direction Y, the seventh sub-arm 1264c extends along the first direction X and is opposite to the fourth sub-arm 1262b; the eighth sub-arm 1264d extends along the second direction Y and is located between the first sub-arm 1260a and the sixth sub-arm 1264b; the ninth sub-arm 1264e extends along the first direction X and is close to the second sub-arm 1260b. The arrangement of the eighth sub-arm 1264 d and the ninth sub-arm 1264 e can satisfy the length requirement of the third radiation arm 1264 on the one hand, and can avoid the first radiation arm 1260 on the other hand, thereby avoiding interference with the first radiation arm 1260 .
[0053] See also Figure 5 As shown, Figure 5 A second structural schematic diagram of an antenna assembly provided in an embodiment of the present application. In the second mode, the antenna assembly 100 may have four different radiation frequency bands. Exemplarily, the antenna assembly 100 has a first direction X, a second direction Y, and a third direction Z that are perpendicular to each other.
