Description

Technical Field

[0001] The present application relates to the field of electronic technology, and particularly to a housing assembly and a terminal device. Background Art

[0002] Generally, mobile phone brands will launch multiple models with different configurations in the same series at the same time, such as launching models with different types of battery covers. Generally speaking, among the models in the same series, different types of battery covers are basically the same in overall structure, but only different in local appearance. For example, generally, glass battery covers and leather-patterned battery covers will bulge slightly at the rear camera module avoidance hole, which is a small crater shape, but the ceramic battery cover is basically a large crater shape at the rear camera module avoidance hole. In order to prevent the battery cover from being damaged or collapsing due to lack of support at the crater shape, generally, the main board bracket is used to provide support for it. For battery covers with different crater shapes, different types of main board brackets need to be configured. The main board bracket has a complex shape and a relatively high mold opening cost. At the same time, the main board bracket providing support for the battery cover is not conducive to laser engraving LDS antennas or applying flexible antennas.

[0003] Therefore, it is necessary to improve the existing housing assembly, enhance the versatility of the main board bracket, and reduce the cost incurred for providing support for the battery cover. Utility Model Content

[0029] It should also be further understood that the term "and / or" used in the specification and appended claims of the present application refers to any combination and all possible combinations of one or more of the related listed items, and includes these combinations.

[0030] In this document, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0031] In addition, in the description of the present application, the terms "first", "second", etc. are only used for distinguishing descriptions, and cannot be understood as indicating or implying relative importance.

[0032] The technical solution provided by this application is applicable to terminal devices. The terminal device can be a mobile phone, a tablet computer, a laptop computer, a smart bracelet, a smart watch, a smart helmet, a smart glasses, etc. The terminal device can also be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless communication function, a computing device or other processing devices connected to a wireless modem, a vehicle-mounted device, an electronic device in a 5G network or an electronic device in a future evolved public land mobile network (PLMN), etc. The embodiments of this application do not limit this.

[0033] Figure 1 , Figure 2 Exemplarily, a partial structure (housing assembly) of the terminal device provided by this application is shown, taking the terminal device as a mobile phone for illustration. The terminal device includes a screen, a battery cover 2 (rear shell), a main board, a battery, a main board bracket 1, a rear module, a rear module decoration piece and a spacer 3. And the housing assembly, as a partial structure of the terminal device, includes the main board bracket 1, the battery cover 2 and the spacer 3. The battery cover 2 is provided with a convex portion 4, the convex portion 4 corresponds to the position of the main board bracket 1, and the convex portion 4 is provided with a first avoidance hole 5 for avoiding the rear module of the terminal device; the spacer 3 is provided with a second avoidance hole 6, the spacer 3 is clamped between the main board bracket 1 and the convex portion 4, and both sides of the spacer 3 are respectively attached to the inner sides of the main board bracket 1 and the convex portion 4, and the second avoidance hole 6 corresponds to the position of the first avoidance hole 5.

[0034] It can be understood that with the development of electronic technology, the functions of the rear module of terminal devices such as mobile phones (the rear module, for example, integrates structures such as a camera, a photosensor, a fill light, etc.) are continuously enhanced, the volume of the rear module is getting larger and larger, and it is necessary to open an avoidance hole (the first avoidance hole 5) on the battery cover 2 (rear shell) to make the rear module protrude and use the rear module decoration piece to cover and protect it outside. In order to make the shape of the battery cover 2 coordinated with the protruding rear module and achieve a good visual effect, the part of the battery cover 2 around the first avoidance hole 5 will bulge backward to form the convex portion 4. Among models of the same series with different configurations, the shapes of the convex portions 4 on the battery cover 2 are also different.

[0035] In the prior art, the convex portion 4 is supported by the main board bracket 1. For the battery covers 2 with different convex portions 4, different main board brackets 1 need to be mold-produced to support the convex portion 4. However, the structure of the main board bracket 1 is complex and requires a high mold cost, which greatly increases the manufacturing cost of mobile phones. In addition, the outer shape of the main board bracket 1 that supports the convex portion 4 is adapted to the inner side of the convex portion 4, lacking a relatively flat area, which is not convenient for laser-direct-structuring (LDS) antenna engraving or flexible antenna application.

[0036] In this embodiment, referring to Figure 1 , Figure 2 , Figure 4 , Figure 1 and Figure 2 , the main board bracket 1 is the same as that in Figure 1 and Figure 2 , except that the convex portion 4 of the battery cover 2 is different, which also results in different cushion blocks 3 in Figure 1 and Figure 2 . For the battery covers 2 with different convex portions 4, different cushion blocks 3 can be configured so that the main board bracket 1 can be universal. By arranging the cushion block 3 between the battery cover 2 and the main board bracket 1, the structure of the main board bracket 1 is simplified, enabling the same main board bracket 1 to be shared among models in the same series, saving the mold cost of the main board bracket 1. At the same time, the peripheral area of the simplified main board bracket 1 has a simple outer contour, and the outer contour area of the main board bracket 1 can be used as the engraving area 7, where it is convenient to engrave the LDS antenna or apply the flexible antenna.

[0037] It can be understood that a flexible antenna or an LDS antenna can be arranged between the main board bracket 1 and the cushion block 3. When the LDS antenna is arranged, the LDS antenna can be engraved on the side of the main board bracket 1 close to the battery cover 2.

[0038] As can be seen from Figure 3 , Figure 1 and Figure 2 , the cushion blocks 3 in two different embodiments are different, where the thickness of the b cushion block is greater than that of the a cushion block. In one embodiment, the b cushion block at least includes two parts (or two layers), and one part is the same as the a cushion block. When the b cushion blocks are produced in excess, the part of the b cushion block that is the same as the a cushion block can be used as the a cushion block, and when the a cushion blocks are produced in excess, the a cushion blocks can be used in the b cushion block, which can improve the universality of the a cushion block, improve the resource utilization rate, and reduce material waste.

[0039] It is easy to understand that the spacer 3 can be made of plastics, such as polycarbonate (PC), acrylonitrile-butadiene-styrene copolymer (ABS), thermoplastic polyurethane elastomer (TPU). Preferably, TPU material is selected. The TPU material has good processability, and the surface of the molded product is smooth, with high strength and environmental protection. In addition, the spacer 3 made of TPU material has elasticity, which can play a buffering role when the mobile phone drops, and can reduce the risk of the mobile phone being broken.

[0040] It should be noted that the battery cover 2 can be made of hard materials, such as ceramics or glass, or can be made of soft materials, such as leather.

[0041] On the other hand, the present application provides a terminal device, and the terminal device adopts the foregoing housing assembly. For the specific structure of the housing assembly, reference is made to the foregoing embodiments. Since the present terminal device adopts the technical solutions of the foregoing embodiments, it has at least the beneficial effects brought by the technical solutions of the foregoing embodiments, which will not be elaborated herein one by one.

[0042] It should be noted that the above embodiments can be freely combined according to needs. The above is only the preferred embodiment of the present application. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present application, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present application.
