In some related technologies, a radiator is usually formed by slotting a metal frame of the device, and although the metal frame can be filled with a broken seam of the frame by plastic parts, the texture and the color of the plastic material are different from those of the metal frame, and a fall appears visually, so that the appearance is affected.

Based on this, this disclosure provides an electronic equipment, can set up the radiator in electronic equipment's inside in this electronic equipment, is favorable to the design of all-metal integration back lid, promotes pleasing to the eye.

Specifically, as shown in fig. 1-3, the electronic device 100 may include a metal rear cover 1, a protective sheet 2, an antenna support 3 and a radiator 4, where the metal rear cover 1 may include a body 11 and a support ring 12, the body 11 may further include an opening 111, the support ring 12 is disposed around the opening 111, the protective sheet 2 may be disposed in the support ring 12, the antenna support 3 is stacked under the protective sheet 2 and the antenna support 3 is locally adhered to the protective sheet 2, and the radiator 4 is disposed on a surface of the antenna support 3 facing the protective sheet 2, where the disposition area of the radiator 4 is different from an adhesion area of the antenna support 3 and the protective sheet 2, so that the radiation performance of the radiator 4 is prevented from being affected due to colloid disposition, or the radiator 4 is prevented from being deformed, the radiation effect of the antenna is affected, and the material is saved due to the reduction of the adhesion area. The camera can be arranged in the electronic equipment 100, the lighting surface of the camera is arranged towards the protective sheet 2, and the avoidance opening corresponding to the camera can be arranged on the antenna bracket 3 so as to prevent the antenna bracket 3 from shielding the lighting of the camera, and meanwhile, the protective sheet 2 is arranged as a light-transmitting sheet so as to prevent light from being blocked.

With this, can set up the radiator 4 in the inside of electronic equipment 100 in this disclosure, can reduce the fracture that forms on the frame of body 11, need not to set up under the circumstances of other radiators on the frame of this body 11, can realize that all-metal does not have the design of slotting frame, promote pleasing to the eye degree. For example, the electronic device 100 may include a flat board, and since the number of the antenna arrangements of the flat board is far smaller than that of the antenna arrangements of the mobile phone terminal, when the radiator 4 covers the wifi2.4g frequency band and the wifi5g frequency band, and uses the antenna as the wifi antenna, no other radiator is required to be set on the frame of the flat board, and thus, the full-metal seamless design of the flat board can be realized.

Wherein, the supporting ring 12 can be a hollow cylindrical structure, and the peripheral edge of the protecting sheet 2 is contacted with the inner wall of the supporting ring 12; or, this support ring 12 is hollow cylindrical setting, still includes simultaneously from the annular boss of inner wall inwards extension, and protection piece 2 can set up in this annular boss face that deviates from antenna boom 3 to this can be spacing protection piece 2 through the setting of annular boss, avoids protection piece 2 excessively to push down and leads to the deformation of radiator 4. The protection sheet 2 can shield the annular opening area of the support ring 12 and the protection sheet 2 can be flush with the outer side end part of the support ring 12, thereby improving the attractiveness; the antenna bracket 3 may be partially disposed in the hollow area of the support ring 12, and partially penetrate through the opening 111 on the body 11; alternatively, the antenna support 3 may be integrally located in the hollow area of the support ring 12, and may be specifically designed according to the size of the antenna support 3. The radiator 4 may include an LDS radiator or an FPC radiator, which is not limited by the present disclosure.

As shown in fig. 4 and 5, the antenna support 3 is provided with a surface protection bonding area 31 and an antenna area 32 facing the protection sheet 2, the protection sheet 2 is provided with the bonding area 31, and the radiator 4 is provided in the antenna area 32, and compared with the scheme that the whole surface of the antenna support is bonded with the protection sheet 2 in the related art, the bonding area is reduced, no colloid is bonded between the area of the antenna area 32 and the protection sheet 2, and the risk of the protection sheet 2 being crushed is increased. Accordingly, as shown in fig. 4, the antenna support 3 may further include a boss 33 extending from the antenna region 32 toward the protective sheet 2, and the boss 33 may be penetrated with the radiator 4 to contact the protective sheet 2, thereby supporting the protective sheet 2 through the boss 33, improving structural reliability, and reducing the risk of the protective sheet 2 being crushed.

The plane where the antenna area 32 is located and the plane where the bonding area 31 is located may be different areas located on the same plane of the antenna support 3, or the antenna support 3 may further include an area where a part of the surface facing the protective sheet 2 is recessed inwards to form the antenna area 32, at this time, the radiator 4 may be disposed on the bottom surface of the antenna area 32, and the antenna area 32 and the bonding area 31 may be obviously distinguished by forming the antenna area 32 in an inwards recessed manner, which is beneficial to the assembly of the radiator 4. The relative positional relationship between the adhesive 31 and antenna 32 areas may be designed as desired, for example, in some embodiments, the adhesive 31 and antenna 32 areas may be disposed side-by-side or diagonally; alternatively, in other embodiments, as shown in fig. 4 and 5 of the present disclosure, the bonding area 31 may be disposed around the antenna area 32, where the antenna area 32 is located in a middle area of a surface of the antenna support 3 facing the protection sheet 2, so that, on one hand, the bonding area 31 that may be circumferentially surrounded is bonded to the protection sheet 2, which is beneficial for improving the installation stability of the protection sheet 2, and on the other hand, the antenna area 32 is disposed in the middle, which is beneficial for increasing the distance between the radiator 4 and the support ring 12 and the surrounding cameras, so as to construct a better radiation environment, and is beneficial for improving the radiation effect of the radiator 4.

Through multiple simulations and experiments by the inventor, still as shown in fig. 5, a single boss may be disposed near the center of the antenna region 32, and the end surface area of the single boss 33 is greater than or equal to a first set area, which may be equal to 20mm ² The structural reliability of the protection sheet 2 can be ensured, for example, in some embodiments, the end surface area of the single boss 33 may be equal to 27mm ² . By the design of the single boss 33, the structural stability of the protection sheet 2 can be improved, meanwhile, the number of the bosses 33 is small, and the forming process of the antenna bracket 3 is relatively simple.

However, the area of the single boss 33 needs to be as high as 20mm ² As described above, the occupied area of the antenna region 32 is relatively large, and the radiation efficiency of the radiator 4 is relatively greatly affected. Accordingly, as shown in fig. 6 and 7, the antenna mount 3 includes a plurality of bosses 33, the plurality of bosses 33 are arranged along the diagonal line of the antenna region 32, and the sum of the end surface areas of the plurality of bosses 33 is smaller than the second set area. As shown for example in fig. 6 and 7, the body portion of the antenna section 32 is arranged substantially square, and the antenna mount 3 comprises three bosses 33 arranged along the diagonal of the body portion of the antenna section 32. The sum of the end surface areas of the three bosses 33 is smaller than that of the second designFixed area, e.g. may be less than 15mm ² For example, the sum of the end surface areas of the three bosses 33 is equal to 12mm ² Compared with the scheme of setting of a single boss 33, the structure stability of the protection sheet 2 can be met by arranging the bosses 33 in the diagonal direction, the occupied area of the bosses 33 can be reduced, the effective radiation area of the radiator 4 can be increased, the throughput test of the wifi antenna is facilitated, and the user experience is improved.

Specifically, software simulation analysis is performed on the radiation condition of the radiator 4 under the condition of the single boss 33 and the radiation condition of the radiator 4 under the condition of the plurality of bosses 33, as shown in fig. 8 and 9, an S11 curve and a radiation efficiency curve of the radiator 4 under the condition of the single boss 33 are obtained, as can be seen from fig. 8, the resonance of the radiator 4 at the first identification point can better cover the wifi2.4g frequency band, the resonance at the second identification point can better cover the wifi5g frequency band, and as can be seen from fig. 9, the radiation efficiency at the wifi5g frequency band (i.e. at the second identification point in fig. 9) can be close to-2 dB, the radiation efficiency is good, and the radiation efficiency at the wifi2.4g frequency band (i.e. at the first identification point in fig. 9) can be close to-6 dB, although the radiation efficiency is relatively low, and the use requirement is satisfied. As shown in fig. 10 and 11, an S11 curve and a radiation efficiency curve of the radiator 4 in the case of a plurality of bosses 33 are obtained; according to fig. 10, the resonance of the radiator 4 at the first identification point can better cover the wifi2.4g frequency band, the resonance at the second identification point can better cover the wifi5g frequency band, and according to fig. 9, the radiation efficiency at the wifi5g frequency band (i.e. between the third identification point and the fourth identification point in fig. 11) can be close to-3 dB, the radiation efficiency is good, and the radiation efficiency at the wifi2.4g frequency band (i.e. between the first identification point and the second identification point in fig. 11) can be close to-5 dB. Comparison shows that the radiator 4 under two conditions can both cover wifi2.4g frequency channel and wifi5g frequency channel well to all possess good radiant efficiency at wifi5g frequency channel, and the efficiency bottleneck of wifi2.4g frequency channel under the single boss 33 condition can be optimized in the arrangement of a plurality of bosses 33, promotes the radiant efficiency of radiator 4 at wifi2.4g frequency channel.

In the description herein, the antenna support 3 includes three bosses 33 as an example, and in other embodiments, the antenna support 3 may include two bosses 33, or four bosses 33 or more than four bosses, which is not limited in the present disclosure.

In the above-described embodiment, as shown in fig. 12, in order to feed the feeding signal to the radiator 4, the electronic device 100 may further include a circuit board 5, the circuit board 5 being disposed at a side of the antenna support 3 facing away from the radiator 4, and the radiator 4 may be electrically connected to a feed terminal disposed on the circuit board 5. In order to provide a good clearance environment for the radiator 4, the circuit board 5 may further include a metal avoidance area (not shown) disposed corresponding to the boss 33, where the metal avoidance area may be a through hole formed on the circuit board 5 and corresponding to the boss 33 and penetrating the circuit board 5, or the metal avoidance area may be a through hole formed on a copper foil layer on the circuit board 5 and corresponding to the boss 33, which may be designed according to the requirement.
