Description

Electronic device

Technical Field

The application relates to the field of terminal equipment, in particular to electronic equipment.

Background

Electronic devices are often designed with one-piece appearance pieces for the purpose of pursuing a neat and consistent appearance. The appearance piece is provided with a main body and a side wall, and the side wall is bent relative to the main body. The inside of the appearance piece requires a mounting housing to support the appearance piece. Due to the bending transition structure of the appearance piece, when the shell and the appearance piece are assembled, the shell is easy to collide with the side wall. This can result in excessive side wall stress and susceptibility to damage, reducing the reliability of the appearance.

SUMMERY OF THE UTILITY MODEL

The technical scheme of the application provides an electronic equipment, can solve the uneven problem of outward appearance spare atress because the collision leads to when casing and outward appearance spare equipment.

The electronic equipment comprises an appearance piece, a first shell and a second shell; the appearance piece comprises a main body part, a first side part and a second side part, wherein the first side part and the second side part are respectively connected to two opposite sides of the main body part; the first shell is positioned in the accommodating cavity and comprises a first anti-collision part and a supporting part connected with the first anti-collision part, the first anti-collision part is connected with the first side part and positioned between the first side part and the supporting part, and the material hardness of the first anti-collision part is less than that of the supporting part; the second shell is positioned in the accommodating cavity; the first housing and the second housing are adjacent side by side in a direction from the first side portion to the second side portion, and the second housing is connected with the main body portion and the second side portion.

In the technical scheme, the appearance piece is a part which is exposed outside and can be directly observed by a user in the electronic equipment. The appearance piece may be a component having only a mechanical function, such as a housing; or the external appearance element may be an electronic component such as a display screen (which may be referred to as a home screen). The body portion may be a plate-like structure having a substantially uniform or non-uniform thickness. The first and second side portions may be substantially identical or different in structure. The first side portion and/or the second side portion may be a plate-like structure having a substantially uniform thickness or a non-uniform thickness. Taking the first side portion as an example, the first side portion may be a flat plate structure or formed by connecting at least two flat plate structures end to end, and the first side portion may be connected with the main body portion at an included angle. Alternatively, the first side portion may be a bent plate structure (e.g., an approximately arc-shaped plate), and the first side portion may be in bending transition with the main body portion. The first side portion is connected with the main body portion in such a structure, which can be referred to as that the first side portion is bent relative to the main body portion, that is, a path from the main body portion to the first side portion has a bending tendency.

In this application technical scheme, first casing is adjacent side by side with the second casing, and not range upon range of setting in electronic equipment's thickness direction. The first shell and the second shell support the appearance piece together. The first anticollision portion of first casing separates supporting part and first lateral part, and first anticollision portion contacts with first lateral part and is connected, and the supporting part does not contact with first lateral part and also does not connect. The material hardness of the first anti-collision part is less than that of the supporting part, namely the texture of the first anti-collision part is softer, and the texture of the supporting part is harder. The supporting portion is mainly used for guaranteeing the structural strength of the first shell, so that the first shell can better support the first side portion, and the hardness of the supporting portion can be set according to the requirement.

When the inner wall with first casing and first lateral part is in coordination, because first anticollision portion texture is softer, first anticollision portion is comparatively gentle to the striking of first lateral part, and the impact that first lateral part received is less, and first lateral part is difficult for damaging, and this makes the reliability of outward appearance piece obtain promoting. Furthermore, in consideration of manufacturing accuracy and/or assembly accuracy limitations, the first housing may not be in close contact with the inner wall of the first side portion, and a part of the first housing may be in point contact or line contact with the inner wall of the first side portion. However, because the outer layer of the first shell is the first anti-collision part with a relatively soft texture, even if the first anti-collision part is in point contact or line contact with the inner wall of the first side part, the inner wall of the first side part cannot be seriously extruded or collided, so that stress concentration on the inner wall of the first side part can be avoided, and the risk of damage to the first side part is reduced. Based on this, the reliability of the appearance piece is improved.

In one implementation, the first side portion is curved and encloses a first accommodating space, and at least a portion of the first anti-collision portion is located in the first accommodating space. In this implementation, the first side portion may be a bent plate-like structure; or the structure can be a plate-shaped structure formed by connecting a plurality of flat plate structures end to end, wherein the adjacent flat plate structures form an included angle. The first receiving space may have a corresponding shape. The first anti-collision part can basically just fill the first accommodating space, namely the boundary of the first anti-collision part is basically flush with the boundary of the first accommodating space; or only part of the first anti-collision part is positioned in the first accommodating space, and part of the first anti-collision part exceeds the first accommodating space; or the first anti-collision part is completely positioned in the first accommodating space, but the boundary of the first anti-collision part is retracted into the boundary of the opening of the first accommodating space. With limited manufacturing and/or assembly accuracy, the curved first side portion may be susceptible to impact, crushing, and bumping when mated with the first housing. However, because this implementation has designed the softer first anticollision portion of texture, can reduce impact, extrusion and the top impact that first side portion received, can avoid the inner wall of first side portion to produce stress concentration, reduce the impaired risk of first side portion to make the reliability of outward appearance piece obtain promoting.

In one implementation, the first anti-collision part encloses a second accommodating space, and at least part of the supporting part is located in the second accommodating space. In this implementation, the supporting portion may substantially just fill the second accommodating space, that is, the boundary of the supporting portion is substantially just flush with the boundary of the opening of the second accommodating space; alternatively, only part of the supporting part is positioned in the second accommodating space, and part of the supporting part exceeds the second accommodating space; alternatively, the supporting portion may be entirely located in the second receiving space, but the boundary of the supporting portion is retracted within the boundary of the opening of the second receiving space. The support portion may have a shape adapted to the second receiving space. This kind of design of first anticollision portion and supporting part can carry out good support to first side, ensures the effect of carrying out collision avoidance to first side simultaneously.

In one implementation, the supporting portion is located in the second accommodating space, and the supporting portion fills the second accommodating space, that is, the boundary of the supporting portion is substantially flush with the boundary of the second accommodating space. The design of the supporting part can enable the first shell to well support the first side part, and also enables the first shell to be compact in structure and convenient to assemble.

In one implementation, the first impact prevention portion includes a connecting portion and a partition portion; the connecting part is connected with the first side part, and the connecting part and the first side part are profiled and form a second accommodating space; the partition part is connected with the inner wall of the second accommodating space and divides the second accommodating space into different areas; each zone is provided with a support part, at least part of which is located within the zone. In this implementation, the shape of the connecting portion of the first bumper portion may be similar to the shape of the first side portion. The separating part is positioned on one side of the connecting part, which is deviated from the first side part. The number of the partitions may be n, where n is a natural number greater than or equal to 2. The n separating parts can divide the second accommodating space of the connecting part into n +1 areas, and each area can be provided with one supporting part. For a single support, it may be substantially just full of a single area, i.e. the boundary of the support is substantially just flush with the boundary of the opening of the area; alternatively, the support portion may be only partially within the region, partially beyond the region; alternatively, the support portion may be located entirely within the region, but the boundary of the support portion is recessed within the boundary of the opening of the region. The support may have a shape adapted to the area. The design of the first anti-collision part and the supporting part can enable the first shell to well support the first side part, and meanwhile, the effect of anti-collision protection on the first side part is ensured.

In one implementation, the support portion is located within the area and the support portion fills the area. In this implementation, the support portion within each zone may fill the zone, i.e. the boundary of the support portion is substantially flush with the boundary of the zone. The design of the supporting part can enable the first shell to well support the first side part, and also enables the first shell to be compact in structure and convenient to assemble.

In one implementation, the first shell includes a second bump protection portion, the second bump protection portion is connected with a side of the support portion facing away from the first side portion, and a material hardness of the second bump protection portion is less than a material hardness of the support portion. In this implementation, the support portion may be sandwiched between the first and second anti-collision portions. The texture of the second anti-collision part is soft, and the parts mounted in the appearance piece can be prevented from being damaged by collision. The magnitude relation of the hardness of the materials of the second anti-collision part and the first anti-collision part is not limited, and the two parts can be equal or unequal.

In one implementation mode, at least one first matching part is arranged on the surface of the first anti-collision part at intervals, at least one second matching part is arranged on the surface of the supporting part at intervals, and the at least one second matching part is connected with the at least one first matching part one by one; one of the first matching part and the second matching part is a groove, the other one is a protrusion, and the protrusion is inserted into the groove to form connection. In this implementation, "one-to-one connection" refers to one-to-one connection, that is, one first mating portion is connected to one second mating portion correspondingly. This kind of connection structure is convenient for make, can guarantee the joint strength of first anticollision portion and supporting part, and then ensures that first casing can carry out good support to first side, guarantees to carry out collision avoidance's effect to first side.

In one implementation, the first anti-collision part is connected with the supporting part into a whole. In this implementation, the first housing may be manufactured by an integrated process, such as an in-mold injection molding process, a nano injection molding process, or both the nano injection molding process and the in-mold injection molding process. The first casing size precision of integral type is higher, is convenient for guarantee the equipment precision, is favorable to first casing to carry out good support to first side, guarantees to carry out collision avoidance's effect to first side.

In one implementation, the accommodating cavity is furled at the opening; the end of the first shell far away from the second shell is connected with the first side part, and the end of the second shell far away from the first shell is connected with the second side part. In the implementation mode, the circumferential length of the highest arched part of the inner wall of the accommodating cavity is the largest, and the circumferential length of the opening is smaller than the largest circumferential length. The circumferential length of the inner wall of the accommodating cavity from the highest part of the arch to the opening is reduced. The circumferential length may be calculated by: a plurality of planes which are basically parallel to the main body part are respectively intersected with the inner wall of the containing cavity to obtain a plurality of intersecting lines. The length of each intersection line can be referred to as a circumferential length of the inner wall of the receiving cavity. The first shell and the second shell basically fill the containing cavity, and the first shell and the second shell support the appearance piece with the furled inner cavity together. The appearance piece having the furled inner cavity may be susceptible to impact, crushing and bumping when engaged with the first housing. However, because this implementation has designed the softer first anticollision portion of texture, can reduce impact, extrusion and the top impact that first side portion received, can avoid the inner wall of first side portion to produce stress concentration, reduce the impaired risk of first side portion to make the reliability of outward appearance piece obtain promoting.

In one implementation, the first side portion and the second side portion are both arc-shaped and both arch in a direction away from each other. The arc-shaped bending structure can create full and expanded appearance effects, so that the electronic equipment has better appearance experience and can also enhance the holding feeling of a user. Also, the exterior member having the arc-shaped bent structure may be easily subjected to impact, crush, and knock when being engaged with the first housing. However, because this implementation has designed the softer first anticollision portion of texture, can reduce impact, extrusion and the top impact that first side portion received, can avoid the inner wall of first side portion to produce stress concentration, reduce the impaired risk of first side portion to make the reliability of outward appearance piece obtain promoting.

In one implementation, the bend angle of the first side portion is 90 ° -180 °; and/or the bending angle of the second side part is 90-180 degrees. In this implementation, a tangent L1 of the first side portion is made at a position where the first side portion is connected to the main body portion, a tangent L2 of the first side portion is made at an end portion of the first side portion away from the main body portion, and both the tangent L1 and the tangent L2 are rays. Turning from tangent line L1 to tangent line L2, the angle at which tangent line L1 makes with tangent line L2 is referred to as the bend angle. The bending angles of the first side part and the second side part are independently set and can be the same or different. The bending angle is set in the range, so that the electronic equipment has better appearance experience, and the holding feeling of a user is enhanced. In addition, the reliability of the appearance piece with the bending angle can be improved by designing the first anti-collision part with soft texture.

In one implementation, the first side portion includes at least two flat portions, one of the at least two flat portions is connected with the main body portion and forms an included angle, and every two adjacent flat portions are connected and form an included angle; and/or the second side part comprises at least two flat parts, one flat part of the at least two flat parts is connected with the main body part and forms an included angle, and every two adjacent flat parts are connected and form the included angle. In this embodiment, the first side portion is formed of at least two flat portions, the flat portions of the first side portion are substantially flat, and a bending angle is formed between adjacent flat portions. The appearance of the appearance piece is hard, and certain application scenes can be met, for example, the application scenes of electronic equipment serving as outdoor display equipment. Also, such a design piece having bent corners may be susceptible to impact, crushing, and bumping when mated with the first housing. However, because this implementation has designed the softer first anticollision portion of texture, can reduce impact, extrusion and the top impact that first side portion received, can avoid the inner wall of first side portion to produce stress concentration, reduce the impaired risk of first side portion to make the reliability of outward appearance piece obtain promoting.

In one implementation, the material hardness of the first impact-prevention portion is shore D60 degrees to shore D90 degrees, such as shore D60 degrees, shore D70 degrees, shore D80 degrees, shore D90 degrees.

First anticollision portion and supporting part are made to the material more than using, can realize avoiding the inner wall of first side to produce the purpose that stress concentration, guarantee the structural strength and the manufacturability of first casing.

In one implementation, the appearance piece is a display screen. In this implementation, because the display screen has the first lateral part and the second lateral part that relative main part is buckled, consequently the demonstration visual angle of this display screen is great, can promote user experience. And, through the softer first anticollision portion of design texture, can carry out collision avoidance to the display screen that needs key protection, promote the reliability of display screen.

The electronic device will be described below as an example of a mobile phone.

In one embodiment, as shown in fig. 1 and 2, the electronic device 10 may include an exterior member 11, a first housing 12, a second housing 13, a cover member 14, a circuit board assembly 16, and a conductive member 15.

The exterior member 11 is a part exposed to the outside of the electronic device 10 and directly observable by a user. The appearance piece 11 may be a component having only a mechanical function, such as a housing. Or the external appearance element 11 may also be an electronic component such as a display screen (which may be called a main screen), in particular a curved screen. In one mode, the display screen can comprise a cover plate and a display layer which are attached to each other. The cover plate protects the display layer and can be touched by a user. The display layer can be formed by overlapping multiple layers of materials, and the display layer is provided with a plurality of pixels and can realize display. In another mode, different from the above mode, the display screen may further include a circuit structure for driving and controlling the display layer, such as a flexible circuit board, a data line, a driving line, a component, and the like. These circuit structures are provided outside the display layer. Alternatively, in yet another form, several circuit structures, such as data lines, drive lines, and/or components, may be integrated within the display layer.

As shown in fig. 2 and 3, the exterior member 11 may include a first side portion 111, a body portion 112, and a second side portion 113, the body portion 112 being connected between the first side portion 111 and the second side portion 113. The body portion 112 may be a flat plate-like structure or a bent plate-like structure (taking the flat plate-like structure as an example) having a substantially uniform thickness. Alternatively, the main body 112 may have a flat plate-like structure or a bent plate-like structure with a non-uniform thickness. The outer profile of the body portion 112 may be approximately rectangular. The embodiment of the present application does not limit the specific structure of the main body 112.

The first side portion 111 and the second side portion 113 may have substantially the same structure or different structures (for example, the first side portion and the second side portion may be substantially symmetrically distributed on two sides of the main body portion 112). The first side portion 111 and/or the second side portion 113 may be a bent plate-like structure having a substantially uniform thickness or a non-uniform thickness (taking a substantially uniform thickness as an example). The first side portion 111 and the second side portion 113 may each be curved and arched away from each other, e.g., approximately arc-shaped. The structure of the first side portion 111 and the main body portion 112 may be referred to as a bending of the first side portion 111 relative to the main body portion 112, that is, a transition from the flat main body portion 112 to the curved first side portion 111. Similarly, the structure of the second side portion 113 and the main body portion 112 can be referred to as the second side portion 113 being bent relative to the main body portion 112.

The bending angle of the first side 111 and the bending angle of the second side 113 can reach 150 ° -180 ° (including 150 ° and 180 °). As shown in fig. 3, taking the first side portion 111 as an example, the bending angle can be defined by: a tangent L1 of the first side portion 111 is made at a position where the first side portion 111 connects with the main body portion 112, a tangent L2 of the first side portion 111 is made at an end portion of the first side portion 111 away from the main body portion 112, and both the tangent L1 and the tangent L2 are rays. Turning from tangent line L1 to tangent line L2, the angle at which tangent line L1 makes with tangent line L2 is referred to as the bend angle. The bending angle of the first side portion 111 shown in fig. 4 may be 180 °.

In the first embodiment, the bending angle of the second side portion 113 may also be 180 °, that is, the lengths of the first side portion 111 and the second side portion 113 in the bending direction may be one half of the circumference. Alternatively, the bending angle of the first side portion 111 and the bending angle of the second side portion 113 may not be equal, and the lengths of the first side portion 111 and the second side portion 113 in the bending direction may not be equal.

In the first embodiment, the bending angle of the first side portion 111 and the bending angle of the second side portion 113 can reach 150 to 180 degrees, and it can be considered that the two sides of the exterior member 11 form a large arc-shaped bent structure. The large-radian bending structure can create full and expanded appearance effects, so that the electronic equipment 10 has better appearance experience and can enhance the holding feeling of a user.

As shown in fig. 3, the first side portion 111, the main body portion 112 and the second side portion 113 may enclose an accommodating cavity 11a with an opening, wherein an opening 11b is formed between an end of the first side portion 111 away from the main body portion 112 and an end of the second side portion 113 away from the main body portion 112. The receiving cavity 11a may be approximately C-shaped. The receiving cavity is closed at the opening 11 b. The circumferential length of the highest camber of the inner wall of the housing cavity 11a is the largest, and the circumferential length d1 of the opening 11b is smaller than the largest circumferential length. The circumferential length of the inner wall of the housing cavity 11a decreases from the highest point of the bulge to the opening 11 b. The circumferential length may be calculated by: the planes substantially parallel to the main body 112 intersect with the inner wall of the containing cavity 11a to obtain a plurality of intersecting lines. The length of each intersection line may be referred to as a circumferential length of the inner wall of the housing cavity 11 a.

As shown in fig. 3, the first side portion 111 may be curved to enclose a first receiving space 111a, and the first receiving space 111a may be an inner space of the first side portion 111. The first receiving space 111a may be an approximately semicircular open cavity, and an interface (shown by a vertical dotted line at a tangent line L1 in fig. 3) between the first side portion 111 and the main body portion 112 may be a boundary of the first receiving space 111 a. The first receiving space 111a is an area of the receiving cavity 11 a. The first housing space 111a is for housing a first housing 12 (to be described later). The first receiving space 111a has an inner surface 111b (i.e., the inner surface 111b of the first side portion 111).

As shown in fig. 2 and 4, the first housing 12 may be approximately semi-cylindrical, and a cross-sectional shape (a cross-sectional shape perpendicular to an extending direction thereof) thereof may be approximately semi-circular. As shown in fig. 5, the first housing 12 is mounted in the first receiving space 111a of the first side portion 111. For example, the first housing 12 may be connected to the inner wall of the first receiving space 111a, and the connection includes that the first housing 12 is indirectly connected to the inner wall of the first receiving space 111a through a medium (such as glue, foam, etc.), and may also include that the first housing 12 is in direct contact with the inner wall of the first receiving space 111 a. The first housing 12 is entirely located in the first receiving space 111a, and the first housing 12 substantially just fills the first receiving space 111a, i.e. the boundary of the first housing 12 is substantially flush with the boundary of the opening of the first receiving space 111 a.

In other embodiments, only a portion of the first housing 12 is located in the first receiving space 111a, and a portion of the first housing is located outside the first receiving space 111 a; alternatively, the first housing 12 is entirely located in the first housing space 111a, but the boundary of the first housing 12 is retracted within the boundary of the opening of the first housing space 111 a.

As shown in fig. 5, the first housing 12 may include a first collision prevention part 121 and a support part 122, which are connected. The first anti-collision part 121 and the support part 122 may be integrated; alternatively, the first collision prevention part 121 and the support part 122 may be manufactured separately and then assembled together.

As shown in fig. 5 and fig. 2, the first anti-collision part 121 may have a strip shape and a cross-sectional structure of an approximately arc-shaped plate shape. As shown in fig. 5, the first collision avoidance portion 121 may have a surface 121a that is approximately semi-cylindrical. As shown in fig. 3 and 5, the surface 121a of the first anti-collision part 121 and the inner surface 111b of the first accommodating space 111a are substantially contoured (similar to each other). The surface 121a and the inner surface 111b may be in direct contact. Alternatively, the surface 121a and the inner surface 111b may be indirectly connected through a medium, for example, the surface of the surface 121a may be adhered with foam, and the foam is in contact with the inner surface 111 b; or the surface 121a and the inner surface 111b may be adhered by glue. The first collision avoidance portion 121 may substantially just fill the first receiving space 111a, that is, the boundary of the first collision avoidance portion 121 is substantially flush with the boundary of the first receiving space 111 a. In other embodiments, only a portion of the first anti-collision part 121 is located in the first accommodating space 111a, and a portion of the first anti-collision part exceeds the first accommodating space 111 a; alternatively, the first impact prevention portion 121 is entirely located in the first accommodation space 111a, but the boundary of the first impact prevention portion 121 is retracted within the boundary of the opening of the first accommodation space 111 a.

As shown in fig. 5, the first collision avoidance portion 121 having the arc-shaped curved shape may enclose the second receiving space, and an inner surface of the second receiving space 121b may be approximately a semi-cylindrical surface. The second receiving space 121b is for receiving a support portion 122, which will be described later.

In a first embodiment, the first impact-prevention portion 121 may be made of a softer material, for example, the hardness of the material of the first impact-prevention portion 121 may be shore D60 degrees to shore D90 degrees, such as shore D60 degrees, shore D70 degrees, shore D80 degrees, and shore D90 degrees. The first bump guard 121 having such material hardness is advantageous for improving the problem of uneven stress on the first side portion 111 (as will be described later). The modulus of the material of the first impact-prevention portion 121 may be 1000MPa-15000MPa (inclusive), which enables the first impact-prevention portion 121 to have certain deformation performance and also optimizes the problem of uneven stress on the first side portion 111 (described further below). The material strength of the bumper 121 may be 20MPa to 200MPa (inclusive), which provides the first bumper 121 with suitable structural support properties.

In one embodiment, the material of the first bumper portion 121 may be plastic, including but not limited to polybutylene terephthalate (PBT) containing 20% Glass Fiber (GF), Polycarbonate (PC) containing 20% glass fiber, Polyamide (PA), and polyphenylene sulfide (PPS). Alternatively, the material of the first bumper portion 121 may be a bio-based material (a material obtained by extracting and processing components from animals and plants), a composite material, a foamed ceramic, kevlar, a nano cellulose, a carbon fiber, or the like. The first collision avoidance portion 121 cannot transmit electromagnetic waves, and may be an insulator, for example.

As shown in fig. 5 and fig. 2, the supporting portion 122 may be approximately cylindrical or strip-shaped. As shown in fig. 5, the supporting portion 122 is entirely located in the second receiving space 121b of the first collision prevention portion 121. The supporting portion 122 may substantially just fill the second receiving space 121b, i.e., the boundary of the supporting portion 122 is substantially just flush with the boundary of the opening of the second receiving space 121 b. The shape of the supporting portion 122 may be adapted to the shape of the second receiving space 121 b. The inner surface of the second receiving space 121b may cover the supporting portion 122, i.e., the inner surface of the second receiving space 121b may substantially seamlessly adhere to the surface of the supporting portion 122. In other embodiments, only a portion of the supporting portion 122 is located in the second receiving space 121b, and a portion of the supporting portion exceeds the second receiving space 121 b; alternatively, the support portion 122 is entirely located in the second receiving space 121b, but the boundary of the support portion 122 is retracted within the boundary of the opening of the second receiving space 121 b.

In the first embodiment, the supporting portion 122 can be used as a structural bearing component in the first housing 12 for ensuring the structural strength of the first housing 12. The material strength of the support 122 may be 100MPa-500MPa, such as 100MPa, 200MPa, 350MPa or 500 MPa. The material strength of the support portion 122 greatly affects the structural strength of the first housing 12, and the structural strength of the first housing 12 can be better ensured by setting the material modulus of the support portion 122 within the above range. The material modulus of the support 122 may be 40GPa to 100GPa, such as 40GPa, 60GPa, 80GPa, or 100 GPa. The material toughness (or elongation at break) of the support portion 122 may be 1% -20%, such as 1%, 5%, 10%, or 20%. The material modulus and the material toughness of the support portion 122 also have an effect on the structural strength of the first housing 12, and setting at least one of these two material parameters within the respective ranges described above can optimize the structural strength of the first housing 12.

In the first embodiment, the hardness of the material of the supporting portion 122 may be greater than that of the material of the first impact-prevention portion 121, that is, the texture of the supporting portion 122 is harder, and the texture of the first impact-prevention portion 121 is softer. This allows the support portion 122 to maintain a constant surface shape, which facilitates the structural load bearing function of the support portion 122.

In one embodiment, the material of the supporting portion 122 may be metal, such as aluminum profile (model 6013, 6063, 5083, 7075, etc.), die-cast aluminum (model ADC12), magnesium alloy (model AZ91D), copper alloy, or stainless steel (model 301, 304, etc.), etc. Alternatively, the material of the support 122 may be ceramic, kevlar, nanocellulose, composite material, carbon fiber, or the like.

As shown in fig. 6, the surface of the supporting portion 122 facing the first bumper portion 121 may form at least one groove 122a, for example, fig. 6 shows 2 grooves 122 a. These grooves 122a are provided at intervals. The groove 122a may be approximated as a dovetail groove, that is, as shown in fig. 5, the cross-sectional shape of the groove 122a may be approximated as a trapezoid having a wider base and a narrower tip.

As shown in fig. 6, a surface of the first collision prevention part 121 facing the support part 122 may be formed with at least one protrusion 121c, and the number of the protrusions 121c may correspond to the number of the grooves 122 a. These protrusions 121c are provided at intervals. The shape of the protrusion 121c may be adapted to the shape of the groove 122a, that is, as shown in fig. 6, the cross-sectional shape of the protrusion 121c may be approximately trapezoidal, with the root of the protrusion 121c being narrower and the tip thereof being wider. The protrusion 121c is matched with the groove 122a, or the protrusion 121c is inserted into the groove 122a to form connection. The dovetail-shaped groove 122a enables the protrusion 121c to be reliably matched with the groove 122a, and ensures that the first anti-collision part 121 is firmly connected with the supporting part 122.

The shape of the groove 122a on the supporting portion 122 and the shape of the protrusion 121c on the first collision avoidance portion 121 in fig. 6 are merely examples, and the embodiment of the present application is not limited thereto. For example, as shown in fig. 7 (fig. 7 only shows the matching relationship between the first anti-collision part 121 and the supporting part 122, but not limited to the specific structures of the two), in addition to the groove 122a, the surface of the supporting part 122 may be provided with grooves of other shapes, such as a groove 122c approximately in a T shape, and a groove 122b approximately in a circular arc shape (which may be a semicircle, a major arc, or a minor arc). The number of the grooves 122a, 122b and 122c may be at least one. Correspondingly, the protrusion 121d on the first bump guard 121 has a shape matched with the groove 122b, and the protrusion 121d is matched with the groove 122 b; the protrusion 121e of the first bump guard 121 has a shape fitting the groove 122c, and the protrusion 121e fits the groove 122 c.

It is understood that the supporting portion 122 has the groove 122a, the groove 122b and the groove 122c in fig. 7, and the first bumper portion 121 has the protrusion 121c, the protrusion 121d and the protrusion 121e, which are only examples. In practice, the supporting portion 122 may be formed with at least one recess, and the first anti-collision portion 121 may be formed with at least one protrusion.

In the first embodiment, the positions of the groove and the protrusion may be interchanged, that is, the first anti-collision part 121 may have a groove, and the supporting part 122 may have a protrusion, which is engaged with the groove. Therefore, in the embodiment of the present application, it can be considered that a first matching portion is formed on the first collision avoidance portion 121, a second matching portion is formed on the supporting portion 122, and one of the first matching portion and the second matching portion is a groove, and the other is a protrusion. In other embodiments, the first anti-collision part 121 and the supporting part 122 may be connected by other structures or manners, not limited to the cooperation of the protrusion and the groove.

In the first embodiment, the first anti-collision part 121 and the supporting part 122 can be manufactured by an integrated process. For example, the first bump guard 121 and the supporting portion 122 may be formed by an in-mold molding process. The support 122 may be placed into a mold cavity of an injection molding apparatus such that the molten plastic adheres to the surface of the support 122. The plastic and the supporting portion 122 can be reliably combined through processes of pressure maintaining, cooling, and the like, and the first housing 12 is finally obtained. Wherein, the plastic part forms a first anti-collision part 121, and the first anti-collision part 121 and the support part 122 are connected into a whole. The protrusion of the first bump guard 121 may be formed naturally during the adhesion of the molten plastic.

It will be appreciated that the in-mold molding process described above is merely exemplary, and that first housing 12 may be manufactured by other suitable processes. For example, the one-piece first housing 12 may be formed using a nano-injection molding process, or using a nano-injection molding process and an in-mold injection molding process. Alternatively, the first anti-collision part 121 and the supporting part 122 may be manufactured by a suitable process, and then assembled. For example, the supporting portion 122 may be inserted into the second receiving space 121b of the first collision prevention portion 121 in a manner similar to a push-out drawer.

As shown in fig. 2 and 4, the second housing 13 is mounted in the receiving cavity 11a of the exterior member 11, and the second housing 13 may be in direct contact with the inner wall of the receiving cavity 11 a. Alternatively, the second housing 13 may be indirectly connected to the inner wall of the receiving cavity 11a through a medium, for example, foam may be adhered to the surface of the second housing 13, and the foam contacts the inner wall of the receiving cavity 11 a; or the second housing 13 may be adhered to the inner wall of the receiving chamber 11a by adhesive. The first housing 12 and the second housing 13 are disposed side by side adjacent to each other in a direction from the first side 111 to the second side 113. For example, in the perspective of fig. 4, the first casing 12 and the second casing 13 are adjacent side by side in the left-right direction, rather than being stacked in the up-down direction. The first housing 12 and the second housing 13 may be fixedly connected, for example, by bonding, snap-fitting via a snap-fit structure, or by a connecting member (e.g., a screw) or the like. Alternatively, the first housing 12 and the second housing 13 may not be connected, and they may be juxtaposed, and a certain gap may be maintained therebetween. The gap may be small to ensure a reliable support of the outer element 11 by both.

As shown in fig. 4, the shape of the second housing 13 may be adapted to the shape of the receiving cavity 11 a. The second housing 13 may include a first portion 131 and a second portion 132, and the first portion 131 and the second portion 132 may be integrated or assembled together. The first portion 131 may be approximately plate-shaped and may be substantially contoured to the main body portion 112 of the exterior member 11, and the first portion 131 is connected to the main body portion 112. The second portion 132 may be approximately semi-cylindrical, and the cylindrical side of the second portion 132 may be approximately tangential to the surface of the first portion 131 facing the body portion 112. The second portion 132 may also be considered as a fence structure that is raised towards one side of the first portion 131 (e.g., the lower side of the first portion 131 in fig. 4). The second portion 132 may be substantially contoured with the second side 113. The second portion 132 may substantially abut a surface of the second side 113, the second portion 132 being connected to the second side 113.

In the first embodiment, the first housing 12 is located in the first receiving space 111a of the receiving cavity 11a of the exterior member 11, and the second housing 13 substantially occupies the other region of the receiving cavity 11a except the first receiving space 111 a. This design allows the joint line between the second housing 13 and the first housing 12 (i.e., the boundary line between the two) to be close to the first side portion 111 of the exterior part 11, and the main body portion 112 of the exterior part 11 can be supported by a large, continuous surface of the first portion 131 of the second housing 13, thereby ensuring the reliability of the main body portion 112. For example, when the first portion 131 is flat, a larger continuous surface of the first portion 131 can ensure a higher flatness and can more closely fit the main body 112, which is also flat, thereby ensuring reliability of the main body 112.

It is understood that this is merely an example and that the embodiments of the present application are not limited thereto. For example, the size of the first housing 12 may be increased, and the first housing 12 may include a portion located inside the first receiving space 111a and a portion outside the first receiving space 111 a. The first housing 12 is located outside the first receiving space 111a, and supports the main body 112 of the exterior member 11 together with the first portion 131 of the second housing 13.

In the first embodiment, the second housing 13 may also include a first anti-collision portion and a support portion, similar to the first housing 12. For example, the second portion 132 of the second housing 13 may include a first bump guard and a support portion connected. The first bump guard may be connected to the second side portion 113. The supporting portion may include a portion supporting the body portion 112 and a portion supporting the second side portion 113. The portion supporting the body part 112 may be connected with the body part 112. The portion supporting the second side 113 is connected to the first bumper, and the first bumper may separate the portion supporting the second side 113 from the second side 113. Such a second housing 13 can be considered to have a crash-proof design. The material selection and material parameters of the first anti-collision part of the second shell 13 may be the same as those of the first anti-collision part 121 of the first shell 12. The material selection and material parameters of the support portion of the second housing 13 may be the same as those of the support portion 122 of the first housing 12. And will not be repeated here.

It is understood that the second housing 13 having a crash-proof design is an example, and the embodiment of the present application is not limited thereto. The second housing 13 may also include a support portion but no first bumper portion.

In the first embodiment, the first housing 12 and the second housing 13 may be collectively referred to as a housing. The housing may be, for example, a middle frame of the electronic device 10, with the first housing 12 and the second housing 13 each being a one-piece middle frame.

The electronic device 10 in the first embodiment includes a first housing 12 and a second housing 13, which is merely an example. The embodiment of the present invention is not limited to this, and for example, the electronic device may further include another housing, which is adjacent to the first housing 12 and the second housing 13 in parallel and is mounted in the housing cavity 11a of the exterior member 11.

As shown in fig. 3 and 4, the first housing 12, the second housing 13 and the external appearance member 11 may be assembled by first placing the first housing 12 having a smaller size into the first receiving space 111a from the opening 11b of the receiving cavity 11a, then holding the second housing 13 in an inclined posture, and placing one end (referred to as a first end) of the second housing 13 into the receiving cavity 11a from the opening 11b at a position corresponding to the second side portion 113, while the other end (referred to as a second end opposite to the first end) of the second housing 13 does not yet enter the receiving cavity 11 a. After the first end is mounted in place, the second end is placed into the accommodating cavity 11a, and finally the second housing 13 is completely accommodated in the accommodating cavity 11 a.

When the first anti-collision part 121 is matched with the inner wall of the first accommodating space 111a, because the outer layer of the first shell 12 is the first anti-collision part 121 with soft texture, the first anti-collision part 121 has gentle impact on the first side part 111, the impact on the first side part 111 is small, and the first side part 111 is not easy to damage. Similarly, the second housing 13 with the anti-collision design can also make the second side portion 113 less prone to damage. Therefore, the reliability of the exterior member 11 is improved.

In addition, in consideration of the manufacturing accuracy and/or the assembly accuracy, the first housing 12 may not be in close contact with the inner wall of the first housing space 111a, and a part of the first housing 12 may be in point contact or line contact with the inner wall of the first housing space 111 a. However, the outer layer of the first shell 12 is the first anti-collision part 121 which is soft, so that even if the first anti-collision part 121 makes point contact or line contact with the inner wall of the first accommodating space 111a, the inner wall of the first accommodating space 111a is not seriously pressed or collided, stress concentration on the inner wall of the first accommodating space 111a can be avoided, and the risk of damage to the first side part 111 can be reduced. Likewise, when the outer layer of the second housing 13 has the first bumper portion, the risk of damage to the second side portion 113 can be reduced. Based on this, the reliability of the exterior member 11 is improved.

In addition, by designing the split type first housing 12 and the split type second housing 13, the first housing 12 and the second housing 13 can be respectively installed in the accommodating cavity 11a of the exterior piece 11. The split type shell design can meet the requirements that the opening 11b between the first side part 111 and the second side part 113 in the appearance piece 11 is narrow, the overall size of the shell is large, and the assembly problem of the traditional shell and the appearance piece 11 with large-radian curves is solved.

As shown in fig. 2 and 4, the circuit board assembly 16 is located in the receiving cavity 11a and can be fixed on a side of the second housing 13 facing away from the external appearance member 11. The circuit board assembly 16 may be located in a space enclosed by the first portion 131 and the second portion 132. An edge of the circuit board assembly 16 may be proximate the first housing 12. The circuit board assembly 16 may enable electrical control of the electronic device 10 to provide electrical performance to the electronic device 10. The circuit board assembly 16 may include a circuit board, and a circuit disposed on the circuit board. The circuitry may include radio frequency circuitry operable to convert the baseband signals to radio frequency signals. The circuit board can be also provided with a ground pole, the ground pole can be a conductor, and the ground pole can be used as a zero potential reference point of the circuit board.

As shown in fig. 4 and 5, the conductive member 15 may be fixed on the circuit board assembly 16, for example, on a side of the circuit board assembly 16 facing away from the second housing 13. The conductive member 15 may be mounted on the edge of the circuit board assembly 16 to facilitate the connection of the conductive member 15 with the supporting portion 122 of the first housing 12. This connection of the conductive member 15 to the support portion 122 may be an unfixed connection, such as a contact; or may be a fixed connection such as welding, snap-fit, etc. The conductive member 15 has a conductive property and may be made of, for example, a metal material such as copper. The structure of the conductive member 15 is not limited in the embodiment of the present application, for example, the conductive member 15 may be an elastic sheet. The conductive member 15 may be a feeding member (described later) or a grounding member.

In one embodiment, the support portion 122 may be used as an antenna radiator. The supporting portion 122 may be electrically connected to the rf circuit of the circuit board assembly 16 through the conductive member 15 to receive the rf signal, convert the rf signal into an electromagnetic wave signal, and radiate the electromagnetic wave signal. The conductive member 15 can be used as a feeding member to feed rf signals into the supporting portion 122. Taking the example of the supporting portion 122 transmitting the electromagnetic wave signal to realize the antenna output, the supporting portion 122 may actually receive the electromagnetic wave signal to realize the antenna input. Alternatively, the support portion 122 may be an antenna radiator, and the support portion 122 may be electrically connected to the rf circuit in other manners. The conductive member 15 may serve as a grounding member for grounding the supporting portion 122.

The first embodiment of the present invention can make the supporting portion 122 have the functions of both structural support and antenna radiator, thereby avoiding additional antenna radiator and simplifying the product structure.

In addition, when the exterior member 11 is an electronic component, the exterior member 11 may interfere with an antenna signal. However, since the first anti-collision part 121 between the exterior piece 11 and the supporting part 122 cannot transmit electromagnetic waves, that is, does not interfere with the first anti-collision part 121 of the antenna signal, the first anti-collision part 121 can separate the supporting part 122 from the exterior piece 11 that can interfere with the antenna signal, thereby providing an antenna clearance area required by the supporting part 122, and thus ensuring the radiation and reception performance of the supporting part 122.

In other embodiments, the support portion 122 may not function as an antenna radiator.

As shown in fig. 2 and 4, the closure member 14 may be approximately plate-shaped, such as flat or bent. As shown in fig. 3, the cover member 14 may be installed at the opening 11b of the receiving cavity 11a and close the receiving cavity 11 a. The closure member 14 may be a component having only a mechanical function; alternatively, the closure member 14 may be an electronic component, such as a display screen (which may be referred to as a secondary screen), which is defined above and will not be repeated here. When the cover member 14 is also a display screen, the electronic device 10 is capable of a 360 degree wrap around omnidirectional display.

As shown in fig. 8 and 9, in the second embodiment, different from the first embodiment, the first housing 22 of the electronic device 20 may include the first anti-collision part 221, the support part 222 and the second anti-collision part 223, which may be connected together, or they may be manufactured and assembled separately. The first anti-collision part 221 is connected to the first side 111 of the exterior part 11. The support portion 222 is located between the first and second bump guards 221 and 223.

As shown in fig. 9, the structure of the first bumper portion 221 may be similar to that of the first bumper portion 121 described above. For example, the first collision prevention part 221 may have a cross-sectional structure of an approximately arc-shaped plate shape. The first collision avoidance portion 221 substantially follows the first receiving space 111a, and the first collision avoidance portion 221 may be connected to the inner wall of the first receiving space 111a, for example, adhered by adhesive; alternatively, foam may be adhered to the surface of the first bumper 221, and the foam may contact the inner wall of the first receiving space 111 a. The first anti-collision part 221 may also enclose a second receiving space.

As shown in fig. 9, unlike the first collision avoidance portion 121, both ends of the first collision avoidance portion 221 in the circumferential direction (the direction along which the arc extends) may be retracted inside the boundary of the first accommodation space 111a (the boundary of the first accommodation space 111a is indicated by two longer vertical dashed lines in fig. 9, which is merely an illustration for clear expression). In other embodiments, one circumferential end of the first anti-collision portion 221 is retracted inside the boundary of the first receiving space 111a, and the other circumferential end is substantially flush with the boundary of the first receiving space 111a or exceeds the boundary of the first receiving space 111 a. Alternatively, both ends of the first collision prevention portion 221 in the circumferential direction may be substantially flush with the boundary of the first accommodation space 111 a.

The material selection and material parameters of the first impact prevention portion 221 may be the same as those of the first impact prevention portion 121, and are not repeated here.

As shown in fig. 9, the structure of the support portion 222 is similar to that of the first collision avoidance portion 121 described above, and the support portion 222 may have a cross-sectional structure of an approximately arc-shaped plate shape. The boundary of the supporting portion 222 may be substantially just flush with the boundary of the first receiving space 111 a. In contrast, both ends of the support portion 222 in the circumferential direction may exceed the corresponding boundaries of the first collision avoidance portion 221, or both ends of the first collision avoidance portion 221 in the circumferential direction may be retracted into the corresponding boundaries of the support portion 222. This enables the first bump guard 221 to recede from the first side portion 111 of the exterior member 11.

Due to machining accuracy limitations, a smooth transition may not be possible between the first side portion 111 and the main body portion 112, which may cause the first impact prevention portion 221 to collide or bump against the transition region between the first side portion 111 and the main body portion 112. However, since the end of the first anti-collision portion 221 close to the main body 112 in the circumferential direction is avoided, the first anti-collision portion 221 can be prevented from colliding or bumping against the transition region between the first side portion 111 and the main body 112, thereby improving the reliability of the exterior part 11. In addition, due to machining and/or assembly accuracy limitations, a smooth transition between the first side portion 111 and the cover 14 may not be possible, which may cause the first bump guard 221 to collide or bump against the transition region between the first side portion 111 and the cover 14. However, since the end of the first collision avoidance portion 221 adjacent to the cover member 14 in the circumferential direction is avoided, the first collision avoidance portion 221 can be prevented from colliding or bumping against the transition region between the first side portion 111 and the cover member 14, thereby improving the reliability of the exterior member 11.

The connection manner of the support portion 222 and the first anti-collision portion 221 can be the same as that described in the first embodiment. The material selection and material parameters of the supporting portion 222 can be the same as those of the supporting portion 122 in the first embodiment. And will not be repeated here.

As shown in fig. 9, the second bumper portion 223 may have a structure similar to that of the support portion 122, for example, the second bumper portion 223 may be approximately semi-cylindrical. The semi-cylindrical surface of the second collision prevention part 223 may be connected with the support part 222. The connection manner of the second collision avoidance portion 223 and the support portion 222 may be the same as the connection manner of the first collision avoidance portion 221 and the support portion 222, and is not repeated here. In other embodiments, the first housing 22 may lack the second bumper 223.

The material selection and material parameters of the second bumper 223 may be the same as for the first bumper 221 and will not be repeated here. Alternatively, the material hardness of the second bumper portion 223 and the material hardness of the first bumper portion 221 may be different, but both are less than the material hardness of the support portion 222. Due to the soft texture of the second bump guard 223, it is possible to avoid causing a bump damage to a component mounted in the exterior piece 11, which may be, for example, a component disposed on the circuit board assembly 16.

The second embodiment can also have the technical effects of the first embodiment, for example, the reliability of the appearance piece 11 is higher; the difficulty in assembling the traditional shell and the appearance piece 11 with large-radian bending can be overcome; the support 222 may be used as an antenna radiator, and the radiation and reception performance of the support 222 may be ensured; a 360 degree surround omnidirectional display can be achieved. In addition, in the embodiment, by making the first anti-collision portion 221 avoid, the first anti-collision portion 221 can be prevented from colliding or bumping against the transition area between the first side portion 111 and the cover member 14, or the transition area between the first side portion 111 and the main body portion 112, so as to enhance the reliability of the exterior member 11; it is also possible to avoid the occurrence of a collision damage to the components mounted in the exterior member 11.

As shown in fig. 10 and 11, unlike the first embodiment, the first housing 32 of the electronic apparatus 30 of the third embodiment may include a first collision prevention part 321 and two support parts 322.

As shown in fig. 11, unlike the first collision prevention part 121 of the first embodiment, the first collision prevention part 321 of the third embodiment may include a connection portion 3211 and a partition portion 3212.

The structure of the connecting portion 3211 may be similar to that of the first anti-collision portion 121 in the first embodiment, for example, the connecting portion 3211 may have a cross-sectional structure with an approximately arc-shaped plate shape. The connecting portion 3211 may be contoured to the first side portion 111. Both ends of the connecting portion 3211 in the circumferential direction (the direction in which the arc extends) may be substantially flush with the boundary of the first accommodating space 111a of the first side portion 111 (the boundary of the first accommodating space 111a is indicated by two long vertical dashed lines in fig. 9, which is merely an illustration for clarity). The connection portion 3211 may directly contact an inner wall of the first receiving space 111 a. Alternatively, the connection portion 3211 and the inner wall of the first receiving space 111a may be indirectly connected through a medium, for example, foam may be adhered to the surface of the connection portion 3211, and the foam contacts the inner wall of the first receiving space 111 a; or the surface of the connecting portion 3211 and the inner wall of the first accommodating space 111a may be adhered by glue. The connection portion 3211 may enclose a second receiving space 321 a.

The partition 3212 may have an approximately rectangular cross-sectional configuration. The partition 3212 is connected to an inner wall of the second receiving space 321 a. The partition 3212 partitions the second receiving space 321a into an area C1 and an area C2. The partition 3212 may, for example, substantially equally divide the second receiving space 321a, so that the shapes and volumes of the region C1 and the region C2 are substantially equal, for example, the inner wall of the region C1 and the inner wall of the region C2 are both approximately quarter circular arc surfaces. Of course, this is merely an example, the position of the partition 3212 in the second accommodating space 321a may be flexibly set as required, and the shapes and volumes of the region C1 and the region C2 may be adjusted accordingly.

In other embodiments, at least one end of the connecting portion 3211 in the circumferential direction may be retracted within the corresponding boundary of the first receiving space 111a, which is the same relief design as that described in the second embodiment, and thus reliability of the exterior member 11 can be improved.

The material selection and material parameters of the first anti-collision part 321 in the third embodiment may be the same as those of the first anti-collision part 121 in the first embodiment, and are not repeated here.

As shown in fig. 11, a support 322 may be disposed in each of the areas C1 and C2. Brace 322 in region C1 may have a configuration that matches that of region C1, and may substantially fill region C1. Brace 322 in region C2 may have a configuration that matches that of region C2, and may substantially fill region C2. The connection manner of the two supporting portions 322 and the first anti-collision portion 121 can be the same as that described in the first embodiment, and is not repeated here. In other embodiments, the portion of support 322 in region C1 is located within region C1, and a portion may be located outside of region C1. The portion of support 322 in region C2 is located within region C1 and may be partially located outside region C1.

The material selection and material parameters of the two supporting portions 322 can be the same as those of the supporting portion 122 in the first embodiment. And will not be repeated here. Alternatively, the materials of the two supporting portions 322 may be different, but the materials of both supporting portions may be determined from the range of materials that may be selected for the supporting portion 122 in the first embodiment. The material parameters of the two supporting portions 322 may be different, but the material parameters of both supporting portions may be determined from the range of material parameters that may be selected for the supporting portion 122 in the first embodiment.

Each support 322 may act as an independent antenna radiator. Since the two supporting portions 322 are separated by the partition portion 3212, they do not interfere with each other electromagnetically. Alternatively, only one of the support portions 322 may be an antenna radiator, and the other support portion 322 may be a purely mechanical component, and thus, there may be no electromagnetic wave transmission function.

In other embodiments, the number of partitions 3212 may be n, where n is greater than or equal to 2. The n partitions 3212 may divide the second receiving space 321a of the connecting portion 3211 into n +1 regions, for example, each of which may have one supporting portion 322.

The third embodiment can also have the technical effects of the first embodiment, such as making the reliability of the appearance piece 11 higher; the difficulty in assembling the traditional shell and the appearance piece 11 with large-radian bending can be overcome; one or two support portions 322 may be used as an antenna radiator, and the radiation and reception performance of the antenna radiator may be ensured; a 360 degree surround omnidirectional display can be achieved.

As shown in fig. 12 and 13, in the fourth embodiment, the first collision avoidance portion 421 of the first casing 42 of the electronic device 40 may include a connection portion 4211 and a partition portion 3212. In contrast to the third embodiment, one end (for example, one end close to the cover member 14) of the connecting portion 4211 in the circumferential direction (the direction along which the arc extends) may be retracted inward to the corresponding boundary of the first accommodating space 111a (the boundary of the first accommodating space 111a is indicated by two long vertical dashed lines in fig. 13, which is only an illustration for clarity), that is, the end of the connecting portion 4211 is retracted relative to the first side portion 111. The end of the link 4211 that is retracted may correspond to the region C2. The partition 322 located in the region C2 has a space from the first side portion 111. Such an escape design can prevent the connecting portion 4211 from colliding or colliding against the transition region between the first side portion 111 and the cover member 14, and improve the reliability of the exterior member 11. It is understood that the other end (e.g., the end close to the body portion 112) of the connecting portion 4211 in the circumferential direction may be retracted within the corresponding boundary of the first accommodating space 111a according to product requirements.

The solution of the fourth embodiment can also have the technical effects of the third embodiment, for example, the reliability of the appearance piece 11 is made higher; the difficulty in assembling the traditional shell and the appearance piece 11 with large-radian bending can be overcome; one or two support portions 322 may be used as an antenna radiator, and the radiation and reception performance of the antenna radiator may be ensured; a 360 degree surround omnidirectional display can be achieved. In addition, in the fourth embodiment, by making the first anti-collision portion 421 in an avoiding design, the first anti-collision portion 421 can be prevented from colliding or bumping against the transition region between the first side portion 111 and the cover member 14 and/or the transition region between the first side portion 111 and the main body portion 112, so that the reliability of the exterior member 11 is enhanced.

As shown in fig. 14 and 15, in the fifth embodiment, the external appearance piece 51 of the electronic device 50 may include a first side portion 511, a main body portion 112, and a second side portion 513.

Unlike the third embodiment, the appearance member 51 of the fifth embodiment may be approximately in a box shape. For example, the first side portion 511 may include a flat portion 5111 and a flat portion 5112, both of which may be substantially flat plate-like structures. The flat portion 5111 is connected to the flat portion 5112 and forms an included angle, which may be approximately 90 degrees, for example. The flat portion 5111 may be connected to the main body portion 112 and form an included angle, which may be approximately 90 degrees, for example. The second side 513 may have substantially the same structure as the first side 511. The first receiving space 511a surrounded by the first side portion 511 may be approximately square. The housing chamber 51a surrounded by the exterior member 51 is closed at the opening 51 b.

In other embodiments, the first side portion 511 may include one flat portion or at least three flat portions. The included angle between the flat portions and the main body portion 112 and the included angle between the flat portions can be set according to the product requirement, and are not limited to approximately 90 degrees. Accordingly, the shape of the first receiving space 511a surrounded by the first side portion 511 is also adjusted.

As shown in fig. 16, the first collision prevention part 521 of the first housing 52 may include a connection part 5211 and a partition part 3212. Unlike the third embodiment, the shape of the connection portion 5211 of the fifth embodiment may be adapted to the shape of the first receiving space 511a of the first side portion 511, for example, the connection portion 5211 may have a cross-sectional structure of an approximately square frame shape.

The electronic device 50 of the fifth embodiment has a relatively hard appearance, and can meet some application scenarios, for example, the application scenario in which the electronic device 50 is used as an outdoor display device. The fifth embodiment can also have the technical effects of the third embodiment, such as making the reliability of the appearance piece 51 higher; the difficulty of assembling the conventional housing with the appearance piece 51 having a large curvature can be overcome; one or two support portions 322 may be used as an antenna radiator, and the radiation and reception performance of the antenna radiator may be ensured; a 360 degree surround omnidirectional display can be achieved.

In the embodiments of the present application, the designs in the above embodiments may be combined according to product requirements. For example, the structures on different cross-sections of the first housing (which are all parallel to cross-section a-a in fig. 1) may be different, as the structures on two cross-sections may be shown in any two of fig. 5, 9, 11, 13, respectively, or the structures on three cross-sections may be shown in any three of fig. 5, 9, 11, 13, respectively, and so on. To achieve the above design, there may be at least two first housings assembled together, one first housing having only one cross-sectional structure, and different first housings having different cross-sectional structures. Or the first shell is a one-piece component, each section of the first shell has only one cross-sectional structure, and the cross-sectional structures of different sections are different.

The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present application, and shall be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
