The above situation may lead to failure problems of the whole machine in reliability test, such as soft compression and bending failure.

Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of a housing structure according to the present utility model. The housing structure 100 may include, but is not limited to, an antenna structure 110, a body structure 120, and a bridge structure 130. The antenna structure 110 serves as a carrier for radiating or receiving microwave signals. The body structure 120 is used to connect the antenna structure 110 to provide support for the antenna structure 110. In addition, the main structure 120 is used in the intelligent communication device to receive various devices (such as radio frequency circuits) and provide strength of the whole machine. Specifically, the intelligent communication device may be a mobile phone, a tablet computer, a handheld station, and the like. A part of the bridge structure 130 is connected to the antenna structure 110, and another part of the bridge structure 130 is connected to the main structure 120, so as to improve the strength of the antenna structure 110 and the main structure 120.

It will be appreciated that the smart communication device may be subjected to reliability tests, such as soft press tests, bending tests, etc., prior to shipment. If the strength of the antenna structure 110 and the main structure 120 in the smart communication device is not great enough, various tests may fail, and the final product may not meet the requirements of the user. In particular, when the antenna structure 110 needs to be made small and thin or the performance of the antenna structure 110 needs to be improved by increasing the distance between the antenna structure 110 and the main body structure 120, the strength of the antenna structure 110 and the main body structure 120 may be greatly reduced. Therefore, the bridge structure 130 needs to be added to connect the antenna structure 110 and the main body structure 120, so as to improve the strength of the antenna structure 110 and the main body structure 120, thereby improving the structural strength of the whole intelligent communication device.

Further, the bridge structure 130 is disposed on an edge of the main structure 120. The antenna structure 110 and the main structure 120 are arranged at intervals, and the gap bridge structure 130 is arranged between the antenna structure 110 and the main structure 120, so that the gap bridge structure 130 connects the antenna structure 110 and the main structure 120 without affecting the antenna structure 110 to radiate or receive microwave signals.

Optionally, the antenna structure 110, the main body structure 120 and the bridge structure 130 are integrally formed and manufactured by CNC (Computer Numerical Control) to ensure strength and precision of the manufacturing process. The CNC machining may include CNC lathe machining, CNC milling machine machining, CNC boring machine machining, and the like.

Optionally, the antenna structure 110, the main body structure 120, and the bridge structure 130 are made of an aluminum alloy, and may specifically be a high-strength aluminum alloy. The aluminum alloy with high strength, low density and good processing performance can improve the structural strength, reduce the weight and is easy to process.

Further, the length L3 of the main structure 120 is greater than the length L2 of the gap bridge structure 130, and the length L2 of the gap bridge structure 130 is greater than the length L1 of the antenna structure 110, so that the gap bridge structure 130 and the antenna structure 110 can be integrated into the overall profile design of the main structure 120, and the overall appearance is more neat and attractive, and meanwhile, the gap bridge structure 130 is also facilitated to be connected with the main structure 120 from two ends.

Further, the bridge structure 130 may include, but is not limited to, a head portion 131, a middle portion 132, and a tail portion 133, which are sequentially connected. The tail portion 133 of the bridge structure 130 is connected to the antenna structure 110 and the main body structure 120, and the middle portion 132 and the head portion 131 of the bridge structure 130 are connected to the main body structure 120. In this way, both the performance of the antenna structure 110, e.g. the overall transmit power of the antenna structure 110, and the strength of the antenna structure 110 and the body structure 120 are ensured.

Optionally, the head portion 131, the middle portion 132, and the tail portion 133 of the bridge structure 130 are integrally formed. Such as integral injection molding or integral CNC machining, etc., to ensure the overall structural strength of the bridge structure 130.

Further, the body structure 120 includes an edge structure 121 and a slot 122. The edge structure 121 and the slot 122 are disposed adjacent. The antenna structure 110 comprises a bending structure 111. The bending structure 111 faces the main structure 120 and is disposed in the slot 122 of the main structure 120. The width W2 of the slot 122 may be greater than the width W1 of the bent structure 111. The head 131 of the bridge structure 130 connects the edge structure 121 of the body structure 120 across the slot 122. The bending structure 111 is used for radiating or receiving microwave signals. In this manner, the bending structure 111 may be stowed within the body structure 120, making the overall housing structure 100 more compact. The minimum distance between the bending structure 111 and the main body structure 120 is greater than 1mm to ensure the performance of the antenna structure 110.

Further, the housing structure 100 further includes an injection molding 140 (not shown). The injection molding member 140 is fixed to the antenna structure 110, the main body structure 120, and the bridge structure 130. The injection molding 140 may fill the gaps between the antenna structure 110, the main body structure 120, and the bridge structure 130, resulting in a flat, complete housing structure 100.

It will be appreciated that the addition of the bridge structure 130 increases the moment of inertia of the housing structure 100, thereby providing increased strength.

Alternatively, the injection molding 140, the antenna structure 110, the main body structure 120, and the bridge structure 130 may be integrally formed by an in-mold injection molding process.

Alternatively, the material of the injection molding member 140 may be polycarbonate and glass fiber, wherein the ratio of polycarbonate to glass fiber may be (5-15): 1, which may be specifically 5:1, 6:1, 10:1, 12:1, 15:1, etc.

Additionally, the method of manufacturing the housing structure 100 includes the steps of:

s101: the antenna structure, the main body structure and the bridge structure are manufactured through CNC processing technology.

Specifically, the antenna structure 110, the main body structure 120, and the bridge structure 130 are integrally formed aluminum alloy pieces. The antenna structure 110, the main body structure 120, and the bridge structure 130 may be manufactured by CNC machining.

S102: and (3) placing the antenna structure, the main body structure and the bridge structure into a mold, and obtaining a semi-finished product through an in-mold injection molding process.

Specifically, the antenna structure 110, the main body structure 120 and the bridge structure 130 manufactured by the above steps are placed in a special mold, and then an injection molding piece 140 is manufactured by an in-mold injection molding process, and the injection molding piece 140 is connected with the antenna structure 110, the main body structure 120 and the bridge structure 130 by a glue pulling structure, so as to obtain a semi-finished product.

S103: on the basis of the semi-finished product, the reinforcing ribs are cut off through a CNC processing technology to obtain the shell structure.

Specifically, in the semi-finished product obtained in the above step, the head 131 of the bridge structure 130 is provided with a reinforcing rib, and the reinforcing rib is connected with the bending structure 111 of the antenna structure 110, so as to improve the strength of the bending structure 111, thereby avoiding the bending structure 111 from being deformed by plastic melt impact during the in-mold injection process. After the in-mold injection molding process is completed, the reinforcing ribs lose effect. Retaining the stiffener may affect the performance of the antenna structure 110. Therefore, the reinforcing ribs need to be cut off by a CNC machining process on the basis of the semi-finished product. The ribs are cut away to provide the desired shell structure 100.

The housing structure 100 may be applied to a smart communication device to accommodate various devices and provide strength to the whole machine.
