Description

TECHNICAL FIELD

[0001] The utility model relates to electronic equipment technical field especially relates to an antenna module and electronic equipment. BACKGROUND

[0002] In the field of electronic devices, with the continuous improvement of consumer demand for device thinness, durability, cost control and other aspects, electronic devices with full-metal shells gradually become the mainstream choice due to their good structural strength and aesthetics. Full-metal shells not only provide excellent protection performance, but also effectively shield external electromagnetic interference, creating a stable working environment for electronic components inside the electronic device.

[0003] However, the introduction of full-metal shells has brought challenges to the antenna design of electronic devices. Due to the shielding effect of metal on electromagnetic waves, traditional antenna design methods often cannot achieve good signal transmission and reception effects in a full-metal environment. In order to solve this problem, the industry has developed various antenna solutions for electronic devices with full-metal shells, including but not limited to nano-injection molded antennas, flexible printed circuit (FPC) antennas with built-in supports, laser-engraved antennas, and cavity antennas.

[0004] The nano-injection molded antenna solution embeds the antenna part in the metal shell by nano-injection molding, achieving integrated design of the antenna and the metal shell, while avoiding the shielding of the metal on the antenna performance. However, this solution requires high-precision injection molding technology and molds during production, resulting in relatively high costs, which is not conducive to mass production and cost control.

[0005] The cavity antenna solution is to create a specific cavity structure on the metal shell and place the antenna inside the cavity to improve the performance of the antenna using the electromagnetic properties of the cavity. Although this solution performs well in terms of antenna performance, the processing of the cavity and the manufacturing cost of the antenna body are also high, limiting its widespread application.

[0006] The FPC antenna with built-in support and the laser-engraved antenna solution attempt to control costs by reducing the manufacturing cost of the antenna. The FPC antenna with built-in support uses FPC as an antenna carrier and fixes it inside the metal shell through a support. However, the antenna efficiency of this solution is relatively low, and due to the flexibility of FPC and the stability of the support, the antenna performance often fails to meet the ideal state. The laser-engraved antenna is to engrave the shape and pattern of the antenna on the metal shell by laser, although the cost is lower, but the antenna efficiency and performance are also insufficient.

[0007] In summary, the existing antenna scheme applicable to the electronic device with a full-metal shell has certain limitations in cost control, antenna efficiency and performance, etc. Utility model content

Specific implementation

[0034] In order to make the purpose, technical scheme and advantages of the utility model more clear, the technical scheme in the utility model will be described clearly and completely below in combination with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.

[0035] With the introduction of the full-metal shell design of the electronic equipment, the antenna design of the electronic equipment is also challenged, which leads to the increase of the antenna design cost, the obvious reduction of the antenna efficiency and performance. Based on this, the utility model provides a novel antenna design scheme to meet the design requirements of the full-metal shell of the electronic equipment, realize the overall improvement of the cost control, the antenna efficiency and the performance.

[0036] Referring to Figure 1 The utility model provides a kind of antenna module, which is used for being reversibly arranged on the equipment main body, comprising panel 21, metal middle frame 22 and bottom plate 23, metal middle frame 22 is clamped between panel 21 and bottom plate 23, panel 21, metal middle frame 22 and bottom plate 23 are enclosed to form cavity, and the internal device for accommodating antenna module in cavity.

[0037] Wherein, the outer wall of metal middle frame 22 is formed with at least two breaks 221, and metal middle frame 22 is divided into at least two metal segments insulated from each other through at least two breaks 221. Wherein, at least one metal segment constitutes an antenna radiator. The antenna radiator is electrically connected to the equipment main body, and signal transmission can be achieved between the antenna radiator and the equipment main body.

[0038] The utility model discloses an antenna module on which the antenna radiator is arranged outside the equipment main body, and at least part of the metal middle frame of the antenna module is used as the antenna radiator at the same time, so that the metal shell of the equipment main body does not need to be opened for injection molding, thereby reducing the production cost. Moreover, the antenna radiator can rotate with the antenna module, and compared with the traditional antenna design scheme, the utility model can improve the coverage performance and passive efficiency of the antenna.

[0039] Specifically, taking the example that the outer wall of metal middle frame 22 is formed with two breaks 221, metal middle frame 22 is divided into a first metal segment 222 and a second metal segment 223 insulated from each other through the two breaks 221, and at least one of the first metal segment 222 and the second metal segment 223 can be used as an antenna radiator to receive an antenna signal.

[0040] It should be noted that when the first metal segment 222 and the second metal segment 223 are both used as antenna radiators, the first metal segment 222 and the second metal segment 223 can be used as different antennas to receive antenna signals of different frequencies, so as to integrate two antenna radiators on the metal middle frame 22 and adapt to different functional requirements respectively.

[0041] It can be understood that the length of the first metal segment 222 and the second metal segment 223 can be adjusted according to actual needs, and the length of the metal segment can be adjusted by adjusting the distance between the two breaks 221.

The loop antenna has a specific resonant frequency, which can match the frequency of the received signal, thereby improving the reception efficiency.

[0043] Referring to Figures 2-4Each antenna radiator has at least one feed point and one ground point formed on it using laser engraving technology.

Two feed points are formed on the first metal segment 222, and the two feed points are connected to two antenna springs 241 in a one-to-one correspondence. This two-access-point method makes it easier to tune the antenna, without needing to add a lot of matching to tune the impedance. Furthermore, the antenna is not very sensitive and will not deviate too much due to the thickness of the coating process.

[0049] Continue reading Figure 2 The antenna module also includes a functional component 25 disposed within the cavity. In one specific embodiment, the functional component 25 may be at least one of a camera component, a face recognition component, and an iris recognition component, but is not limited thereto.
