Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment housing structures, and in particular to an electronic equipment and a housing assembly thereof. Background Art

[0002] Drop reliability is an important indicator for evaluating the quality of electronic devices such as mobile phones. As one of the most important components of the entire electronic device, the drop reliability of the motherboard is particularly important. The motherboard of an electronic device is the "brain" of the entire electronic device. It integrates a variety of chips, inductors, capacitors, etc., and is fixed to the middle frame of the shell with screws.

[0003] The motherboard carries all the chips and is installed in the middle frame of the electronic device. The electronic device will inevitably be subjected to external forces during the falling process. In the development process of electronic equipment, the motherboard stress needs to be considered, and the stress on the motherboard needs to be reduced from the design perspective (the motherboard stress refers to the force distribution on the motherboard that is transmitted internally when the electronic device is subjected to external loads such as falling) to ensure the safety of the chips on the motherboard and avoid damage to the motherboard when the electronic device falls. However, conventional technical solutions generally use methods such as adding foam to solve the above problems, but the effect of the above methods is limited and cannot solve the problem of drop reliability well. Summary of the invention

[0004] A first aspect of an embodiment of the present application provides a shell assembly, which includes: a main shell, a decorative part and an elastic part; the main shell includes a first surface and a second surface arranged opposite to each other, the main shell is provided with a mounting hole, the decorative part is arranged in the mounting hole and protrudes from the first surface, the decorative part is connected to the main shell through the elastic part, and can elastically shrink along the mounting hole when the decorative part is subjected to force.

[0005] In a second aspect, an embodiment of the present application provides an electronic device, wherein the electronic device includes the housing assembly described in the above embodiment.

[0006] The shell assembly provided in the embodiment of the present application has a structure in which an elastic member is arranged between the decorative member and the shell. When the decorative member receives external force, the elastic member can play a buffering role so that the decorative member can elastically shrink, thereby reducing the impact on the internal components of the electronic device and improving the drop reliability of the electronic device.

[0017] The present application is further described in detail below in conjunction with the accompanying drawings and examples. It is particularly noted that the following examples are only used to illustrate the present application, but are not intended to limit the scope of the present application. Similarly, the following examples are only some embodiments of the present application rather than all embodiments, and all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0018] The terms "first", "second", and "third" in the embodiments of the present application are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Thus, the features defined as "first", "second", and "third" can expressly or implicitly include at least one of the features. In the description of the present application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined. In the embodiments of the present application, all directional indications (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication also changes accordingly. The terms "including" and "having" in the embodiments of the present application and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units that are not listed, or optionally also includes other steps or components inherent to these processes, methods, products, or devices.

[0019] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] As used herein, "electronic devices" (or simply "terminals") include, but are not limited to, devices configured to receive / send communication signals via a wireline connection (e.g., via a public switched telephone network (PSTN), a digital subscriber line (DSL), a digital cable, a direct cable connection, and / or another data connection / network) and / or via a wireless interface (e.g., for a cellular network, a wireless local area network (WLAN), a digital television network such as a DVB-H network, a satellite network, an AM-FM broadcast transmitter, and / or another communication terminal). Communication terminals configured to communicate via a wireless interface may be referred to as "wireless communication terminals", "wireless terminals" or "mobile terminals". Examples of mobile terminals include, but are not limited to, satellite or cellular phones; personal communication system (PCS) terminals that may combine cellular radiotelephones with data processing, fax, and data communication capabilities; PDAs that may include radiotelephones, pagers, Internet / intranet access, web browsers, organizers, calendars, and / or global positioning system (GPS) receivers; and conventional laptop and / or palmtop receivers or other electronic devices that include radiotelephone transceivers. A mobile phone is an electronic device equipped with a cellular communication module.

[0021] In order to reduce the stress on the motherboard of electronic equipment and prevent the motherboard chip from failing when it falls, the commonly used solutions are mainly the following.

[0022] Constrained appearance: The appearance of the phone, such as the length, width, and thickness of the whole phone and the shape of the rear camera decorative parts, especially the shape of the rear camera decorative parts, has a great impact on the stress of the motherboard. Usually, the rear camera decorative parts are protruding designs. When the phone falls, the protruding structure collides with the floor, and the collision generates huge impact energy that is transmitted to the inside of the phone and finally to the motherboard. If the shape of the rear camera decorative parts has a great impact on the stress of the motherboard, the appearance of the phone will be required to be adjusted, such as adjusting the position of the rear camera decorative parts or the protruding height, and the reliability requirements of the phone will conflict with the appearance.

[0023] Optimize motherboard stress through structural design: When the appearance modification is limited, the motherboard stress will be further optimized through structural design. Common methods include: a. Add silicone pads or foam materials, and use the cushioning properties of silicone pads or foam to reduce force transmission; b. Adjust the layout of screws to change the force on the motherboard; c. Design reinforcement ribs to increase the bending strength of the motherboard; d. Adjust the chip layout; e. Other minor structural modifications.

[0024] However, none of the above solutions can effectively solve the problem of drop reliability of electronic devices. When the current existing technology faces a conflict between drop reliability requirements and appearance styling, it is impossible to simultaneously meet the protrusion requirements of the rear camera decorative parts and the reliability requirements of the mainboard stress. In order to ensure that the appearance of the electronic device is competitive, this application proposes a structural solution for a rear camera decorative part.

[0025] The present application embodiment provides an electronic device, please refer to Figures 1 to 3 , Figure 1 is a partial structural diagram of an embodiment of the electronic device of the present application, Figure 2 yes Figure 1 A schematic diagram of the disassembled structure of the electronic device in the embodiment, Figure 3 yes Figure 1 Schematic diagram of the structure of the electronic device along the AA line in the embodiment; it should be noted that the electronic device in the present application may include electronic devices with camera components such as mobile phones, tablet computers, laptops, wearable devices, etc. The electronic device includes but is not limited to the following structures: a housing component 100 and a control circuit board 200.

[0026] For more information, please see Figure 4 , Figure 4 yes Figure 3The enlarged schematic diagram of the structure at B in the embodiment, wherein the housing assembly 100 includes: a main housing 110, a decorative member 120 and an elastic member 130. The main housing 110 may be the back cover of the electronic device, i.e., the battery cover. The main housing 110 includes a first surface 111 and a second surface 112 disposed opposite to each other, the main housing 110 is provided with a through mounting hole 1100, the decorative member 120 is disposed in the mounting hole 1100 and protrudes from the first surface 111, the decorative member 120 is connected to the main housing 110 through the elastic member 130, and can be elastically contracted along the mounting hole 1100 when the decorative member 120 is subjected to force. Optionally, the decorative member 120 and the elastic member 130 in this embodiment may be arranged corresponding to the control circuit board 200 in the thickness direction of the electronic device, or corresponding to the chip arrangement on the control circuit board 200, and the elastic member 130 may play the role of elastic buffering, reducing the impact on the main housing and internal devices (such as the control circuit board 200) when the decorative member 120 is impacted by external force. The elastic member 130 may be a spring or a pre-stressed and compressible material. The main housing 110 may be fixed to the middle frame 300 of the electronic device by double-sided adhesive tape; the control circuit board 200, i.e., the main board (on which all chips are integrated), may be fixed to the middle frame 300 by screws.

[0027] Please also read Figure 5 and Figure 6 , Figure 5 yes Figure 4 The enlarged schematic diagram of the structure at C in the embodiment, Figure 6 yes Figure 4 The enlarged schematic diagram of the structure at D in the embodiment, optionally, the housing assembly 100 in this embodiment further includes a cover plate 140, wherein the cover plate 140 may be a structure such as a flash 210 or a camera covered on the electronic device, which is not specifically limited here. The cover plate 140 may also be provided with a lens 1400.

[0028] The cover plate 140 includes an integral cover body 141 and a connecting portion 142, the connecting portion 142 is arranged along the side circumference of the cover body 141, and the connecting portion 142 is fixedly connected to the second surface 112 of the main housing 110, specifically, it can be fixed by bonding with a double-sided adhesive tape 101. Optionally, the decorative member 120 in this embodiment is an annular structure, the cover body 141 is inserted into the decorative member 120, and the decorative member 120 and the connecting portion 142 are connected by an elastic member 130.

[0029] Optionally, the elastic member 130 in this embodiment can be a spring, which is an annular structure and is fixedly connected to the decorative member 120, specifically by welding. The elastic member 130 is specifically a spring with a square cross section to ensure that the decorative member 120 does not deflect after assembly.

[0030] Optionally, see Figure 5 and Figure 6 In this embodiment, the decorative element 120 is provided with a locking protrusion 121 at one end of the second surface 112 of the main housing 110, and the locking protrusion 121 is locked with the second surface 112 of the main housing 110. A positioning protrusion 143 can also be provided on the connecting portion 142 for positioning with the positioning hole on the main housing 110.

[0031] Optionally, the housing assembly 100 in this embodiment further includes a decorative plate 150, which is fixedly connected to the first surface 111 of the main housing 110, which may be bonded or welded, etc., which is not specifically limited here. The decorative plate 150 is provided with a through hole 151 corresponding to the mounting hole 1100 of the main housing 110, and the decorative member 120 is passed through the through hole 151 and protrudes from the side surface of the decorative plate 150 away from the main housing 110, wherein the amount of the decorative member 120 protruding from the decorative plate 150 is generally more than 0.3 mm, and the stress problem encountered is more serious. The amount of the decorative member 120 protruding from the decorative plate 150 in this embodiment is more than 0.3 mm.

[0032] The decorative part 120 (including the square cross-section spring) is assembled between the decorative plate 150 and the cover plate connection part 142, and the decorative part will not deflect by the hole matching in the XY direction. In the Z direction, the pre-stressing and compressible characteristics of the spring are used. In the non-falling state, that is, the natural state, the decorative part 120 is supported by the spring in a normal "convex" state to achieve the ID effect; when the electronic device falls on the back and the decorative part 120 collides with the floor, the compressible characteristics of the spring are used, and the spring is compressed so that the decorative part 120 can be "retracted", that is, the protrusion of the decorative part 120 changes to a "variable" state, so that the energy of the electronic device falling and colliding is reduced, and the further impact and force transmission of the decorative part 120 to the internal structure is also reduced, and finally the force on the control circuit board 200 (main board) is also relieved, so that the main board chip does not fail.

[0033] In order to solve the mainboard stress problem caused by decorative parts of electronic equipment, a rear camera decorative part solution is designed. This rear camera decorative part solution cleverly utilizes the pre-load characteristics and compressible characteristics of the spring, which not only ensures the barrel protruding effect on the ID appearance, but also solves the mainboard stress problem caused by the impact transmission of the decorative parts when the back falls, so that the product design takes into account both the appearance and the quality reliability of the product.

[0034] Furthermore, the present application also provides an electronic device. The electronic device in this embodiment may include a mobile phone, a tablet computer, a laptop computer, a wearable device, etc. This embodiment is described by taking a mobile phone as an example.
