Some embodiments of the present application are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.

Referring to fig. 1 and fig. 2, an embodiment of the present application provides an electronic device 200. The electronic device 200 includes a main body 201 and a housing assembly 100. The housing assembly 100 includes a shell 10, a structural member 20, a connector 40, a diaphragm 30, and a functional member 50. The housing 10 is sealingly connected to the main body 201. In an embodiment, the electronic device 200 is a mobile phone, the main body 201 is a mobile phone middle frame structure, the housing 10 is a battery cover structure, and the functional component 50 is a camera module, but not limited thereto. The main body 201 is provided with components in the electronic device 200, such as a circuit board, a microphone, and an earphone.

For clarity of the following description, the first direction Z is defined as a thickness direction of the electronic device 200 according to a rectangular coordinate system, the second direction X is a length direction of the electronic device 200, and the third direction Y is a width direction of the electronic device 200.

The housing 10 is provided with a first through hole 101. The functional element 50 is arranged on the side of the structural element 20 facing away from the housing 10. An orthographic projection of the structural member 20 on the housing 10 in the first direction Z covers the first through hole 101. The functional element 50 can be photographed through the first through hole 101. The connector 40 and the diaphragm 30 are in turn disposed between the structural member 20 and the housing 10. The connector 40 is disposed between the structural member 20 and the diaphragm 30. The diaphragm 30 is disposed between the housing 10 and the connecting member 40.

It will be appreciated that in other embodiments, the body 201 may also be a screen and the housing 10 may be used to mount components within the electronic device 200. The body 201 is sealingly connected to the housing 10 such that the components within the electronic device 200 are in a sealed environment.

The connection member 40 has a waterproof function. In an embodiment, the connecting member 40 may be a viscose structure such as a sealant, foam, etc., and opposite sides of the connecting member 40 are adhered to the structural member 20 and the membrane 30, but not limited thereto. It will be appreciated that in other embodiments, the connector 40 may be adhesively secured to the housing 10 and the structural member 20 by an adhesive construction. Alternatively, the connecting member 40 may be non-bonded to the housing 10 and/or the structural member 20, and the connecting member 40 may be secured between the housing 10 and the structural member 20 by clamping the housing 10 and the structural member 20 against opposite sides of the connecting member 40.

In one embodiment, the membrane 30 is a decorative sheet structure with adhesive on one surface, but is not limited thereto. The side of the membrane 30 facing away from the connection 40 is bonded to the housing 10. It will be appreciated that in other embodiments, the membrane 30 may be adhesively secured to the housing 10 by an adhesive construction. The case 10 is of transparent glass structure, but is not limited thereto. The housing 10 covers the side of the membrane 30 facing away from the connection 40, the housing 10 being able to expose the membrane 30 such that the membrane 30 is visible on the outside of the housing 10. The outside of the housing 10 is the side of the housing 10 facing away from the functional element 50. The membrane 30 is used to decorate the housing 10 of the electronic device 200. For example, the membrane 30 may be patterned or may be made of different materials to present different textures. In one embodiment, the membrane 30 is a glare film, but is not limited thereto. When the casing 10 is broken by impact, the broken casing 10 is adhered to the membrane 30, and the danger caused by the breakage of the casing 10 with a glass structure is avoided.

It will be appreciated that in other embodiments, the housing 10 may be a non-transparent glass structure, the membrane 30 need not decorate the housing 10, and the membrane 30 may be a single-sided adhesive film structure. It will be appreciated that the housing assembly 100 may be employed in a structure that includes a functional element 50 that is required to be exposed from the housing 10.

It will be appreciated that in other embodiments, the housing 10 may be partially transparent, with the transparent structure allowing the membrane 30 to be visible from the outside of the housing 10.

In other embodiments, the functional element 50 may be a flashlight module, a decorative nameplate, a fingerprint identification module, etc. The electronic device 200 may also be a tablet computer, a notebook computer, a vehicle-mounted device, a wearable device, an unmanned aerial vehicle, or other products. The wearable device may be a smart watch, virtual Reality (VR) glasses, or the like.

The structural member 20 is provided with a first recess 23. The connecting member 40 and the diaphragm 30 are respectively accommodated in the first groove 23. The first groove 23 provides a mounting space for the diaphragm 30 and the connection member 40, so that a portion of the housing assembly 100 corresponding to the first groove 23 is reduced in thickness.

The structural member 20 is provided with a second recess 25. The second recess 25 and the first recess 23 are located on opposite sides of the structural member 20, respectively. The second recess 25 is adapted to receive the functional element 50. The second recess 25 provides a receiving space for the functional element 50, so that a portion of the housing assembly 100 corresponding to the second recess 25 is reduced in thickness.

The thickness of the portion of the structural member 20 corresponding to the first recess 23 and the second recess 25 may be made to be the minimum thickness required to meet the strength requirement, resulting in a reduction in the thickness of the housing assembly 100 and the electronic device 200.

In one embodiment, the first groove 23 and the second groove 25 are formed on opposite sides of the structural member 20 by milling, but not limited thereto. For example, in another embodiment, the first groove 23 and the second groove 25 may be formed on one side of the structural member 20 by casting.

In one embodiment, the orthographic projections of the first groove 23 and the second groove 25 on the housing 10 along the first direction Z are not coincident. The orthographic projections of the first groove 23 and the second groove 25 on the projection plane along the second direction X are not coincident, respectively. The projection plane is any plane perpendicular to the second direction X, for example, the projection plane may be a plane 400 as shown in fig. 2. The plane 400 is perpendicular to the second direction X.

The region of the functional element 50 located outside the first through hole 101, which is projected on the housing 10 in the first direction Z, is a projection region. The projection area of the functional element 50 is directed to one side of the housing 10, and the portion of the structural element 20 having a distance smaller than or equal to the set value is a zone 51. The set value H1 is 0, but is not limited thereto. In one embodiment, the number of the sections 51 is one, and the side of the section 51 facing the housing 10 is parallel to the plane 501 of the housing 10, but is not limited thereto. When the functional element 50 is fixedly mounted on the structural element 20, the section 51 is in abutment with the structural element 20. The distance between the region 51 and the structural member 20 is 0, and the dimension of the region 51 in the first direction Z of the electronic device 200 is largest in the projection area of the functional member 50. The second recess 25 accommodates the section 51 of the functional element 50 a. The front projection of the diaphragm 30 and the region 51 onto the housing 10 in the first direction Z, respectively, do not coincide. The front projection of the connecting piece 40 and the section 51 respectively in the first direction Z onto the housing 10 does not coincide.

The first groove 23 provides an installation space for the diaphragm 30 and the connecting piece 40, the diaphragm 30 and the area 51 which is smaller than the set value from the structural piece 20 are staggered, and the connecting piece 40 and the area 51 are also staggered, so that the area 51 of the functional piece 50, the diaphragm 30 and the connecting piece 40 are not overlapped in the first direction Z of the electronic equipment 200, the sealing performance of the electronic equipment 200 is ensured, and meanwhile, the thickness is reduced.

The opposite sides of the housing 10 may be provided with groove structures (the first groove 23 and the second groove 25) staggered along the direction parallel to the housing 10, so as to provide the receiving space in the first direction Z for the connecting piece 40, the membrane 30 and the section 51, the section 51 of the functional piece 50 is received in the second groove 25, the first groove 23 and the second groove 25 are staggered along the direction parallel to the housing 10, the section 51 of the functional piece 50, the connecting piece 40 and the membrane 30 are not overlapped along the first direction Z, and the thickness of the electronic device 200 is reduced.

The orthographic projection portions of the first groove 23 and the second groove 25 in the projection plane along the second direction X are overlapped, so that the functional element 50 in the second groove 25 is closer to the housing 10, and the thickness of the electronic device 200 is further reduced.

It will be appreciated that in other embodiments, the set point may be set as desired, and the set point may be greater than 0; the orthographic projections of the second groove 25 and the first groove 23 on the housing 10 along the first direction Z may also coincide, and the orthographic projections of the second groove 25 and the first groove 23 in the projection plane along the second direction X may also not coincide.

For example, in another embodiment, as shown in fig. 3A, in the housing assembly 100a, a plane 501a is formed on a side of the projection area of the functional element 50a facing the structural member 20a, the projection area of the functional element 50a and the structural member 20a need to maintain a set safe distance S, the set value H2 needs to satisfy H2 Σs, and in order to reduce the thickness of the housing assembly 100, the set value H2 is set equal to S, and the plane 501a is the region 51a.

The orthographic projection portions of the first groove 23a and the second groove 25a of the structural member 20a on the housing 10 along the first direction Z are overlapped, and orthographic projections of the first groove 23a and the second groove 25a in the projection plane along the second direction X are not overlapped. The connector 40 and the diaphragm 30 are received in the first recess 23a of the structural member 20 a. The section 51a of the functional element 50a is accommodated in the second recess 25 a. The spacing h between the bottom wall of the first recess 23a and the bottom wall of the second recess 25a is equal to the first threshold h0. The first threshold h0 may be set based on the strength, stiffness, weight, workability, etc. of the structural member 20. The distance h is greater than or equal to the first threshold h0, so that the structural member 20 meets the strength requirement and the rigidity requirement, and the structural member 20 is not easy to deform under the stress.

In yet another embodiment, as shown in fig. 3B, in the housing assembly 100B, a side of the projection area of the functional element 50B facing the structural element 20B includes a curved surface 503a, and a distance between the curved surface 503a and the structural element 20B varies within a certain range. The curved surface 503a is spaced a safe distance S from the structural member 20 b. Setting a set value h3=s+a, a being a rational number greater than 0. A portion (a portion in a broken line frame in fig. 3B) of the curved surface 503a at a distance smaller than H3 from the structural member 20B forms a region 51B. The size of a determines the size of the area of the orthographic projection of the segment 51b on the housing 10.

The orthographic projections of the first groove 23b and the second groove 25b of the structural member 20b on the housing 10 along the first direction Z do not coincide, and the orthographic projections of the first groove 23b and the second groove 25b in the projection plane along the second direction X do not coincide. The spacing w of the two sidewalls of the first groove 23b adjacent to the second groove 25b is equal to the second threshold w0. The second threshold w0 may be set based on the strength, stiffness, weight, workability, etc. of the structural member 20. The spacing w is greater than or equal to the second threshold w0, so that the structural member 20 meets the strength requirement and the rigidity requirement, and the structural member 20 is not easy to deform under the stress.

The connector 40 and the diaphragm 30 are received in the first recess 23b of the structural member 20 b. The section 51b of the functional element 50b is accommodated in the second recess 25 b.

It is understood that in other embodiments, the second direction X may be the width direction of the electronic device 200, and the third direction Y is the length direction of the electronic device 200. The orthographic projections of the first groove 23 and the second groove 25 on projection planes perpendicular to the second direction X (width direction of the electronic device 200) may be coincident or non-coincident, respectively.

The set value is greater than 0, so that the area of the orthographic projection of the area 51b on the housing 10 along the first direction Z is greater than 0, and further the orthographic projections of the connecting piece 40 or the diaphragm 30 and the area 51b on the housing 10 along the first direction Z are staggered, so that the size accumulation of the connecting piece 40 or the diaphragm 30 and the area 51b in the first direction Z is avoided, and the thickness of the electronic device 200 is reduced.

It will be appreciated that in other embodiments, the number of sections 51 may be plural. For example, as shown in fig. 3C, in the case assembly 100C, the projection area of the functional element 50C includes a plurality of curved surfaces 503b and two flat surfaces 501b connected to both sides of the plurality of curved surfaces 503 b. The plurality of curved surfaces 503b form a wave shape. The plane 501b adjacent to the first through hole 101 is at a greater distance from the structural member 20 than the other plane 501b. The distance between the apex of the curved surface 503b near the structural member 20 and the structural member 20 is greater than the distance between the two flat surfaces 501b and the structural member 20. Curved surface 503b is spaced a distance L from structure 20. The set value H4 is greater than L. L is less than the distance from the structure 20 near the plane 501b of the first through hole 101. The distance between the vertex of the curved surface 503b away from the structural member 20 and the structural member 20 is greater than the set value H4. It can be derived that a plurality of sections 51c are formed on each curved surface 503b at a distance from the structural member 20 of less than or equal to H4, and another section 51d is formed near the plane 501b of the first through hole 101. The plurality of sections 51C and 51d are shown in a dashed box in fig. 3C.

The structural member 20c has no second recess. The connector 40 and the diaphragm 30 are received in the first recess 23c of the structural member 20 c. The

sections

51c and 51d of the functional element 50c are located on the side of the structural element 20c facing away from the housing 10.

The front projections of the connecting member 40 and the diaphragm 30 on the housing 10 along the first direction Z are located on the sides of the plurality of

sections

51c and 51d away from the first through hole 101, that is, the front projections of the connecting member 40 and the diaphragm 30 on the housing 10 along the first direction Z are located on the outer peripheral sides of the plurality of

sections

51c and 51d.

The area 51c and the area 51d are not overlapped with the orthographic projection of the first groove 23c on the housing 10 along the first direction Z, so that the thickness of the part of the structural member 20c corresponding to the first groove 23c along the first direction Z can be made to be the minimum thickness meeting the strength requirement, and the thicknesses of the housing assembly 100 and the electronic device 200 are further reduced.

The number of the sections 51 is plural, the connecting piece 40 and the diaphragm 30 are located on the outer peripheral side of the sections 51, and the structural member 20 is easily provided with the first groove 23 with proper sealing dimension, so that the first groove 23 accommodates the connecting piece 40 and the diaphragm 30.

It will be appreciated that in other embodiments, the sections 51B,51C of the curved surfaces 503a,503B shown in fig. 3B and 3C may also be attached to the structural member 20, with the set point being equal to a, if no safety distance is required.

Referring to fig. 2, the electronic device 200 further includes a decoration 60. At least one of the decoration 60 and the structural member 20 passes through the first through hole 101, and the decoration 60 is hermetically connected with the structural member 20.

It will be appreciated that in other embodiments, the trim piece 60 may be sealingly attached to the housing 10.

It will be appreciated that in other embodiments, the trim piece 60 may be secured to the housing 10 or the structural member 20 in a non-sealing manner when the functional element 50 does not require waterproofing.

In one embodiment, the front projection of the diaphragm 30 on the housing 10 along the first direction Z is located on the outer peripheral side of the front projection of the area 51 on the housing 10 along the first direction Z, but is not limited thereto. An orthographic projection of the decoration 60 on the housing 10 in the first direction Z covers the first through hole 101. The decorative piece 60 intersects the front projection of the membrane 30 onto the housing 10 in the first direction Z, respectively. One side of the decoration 60 needs to extend toward the inside of the first through hole 101 to achieve connection of the decoration 60 with the structural member 20; the other side of the decoration 60 extends in the opposite direction to achieve the intersection of the decoration 60 with the orthographic projection of the diaphragm 30 on the housing 10 in the first direction Z, respectively, so that the inside of the housing 10 except the diaphragm 30 cannot be displayed on the outside of the housing 10.

In one embodiment, the connecting member 40 is located in the projection area of the housing 10 and the diaphragm 30 is located in the projection area of the housing 10, but is not limited thereto. I.e. the end face of the membrane 30 facing the first through hole 101 is closer to the first through hole 101 than the end face of the connecting piece 40 facing the first through hole 101. The first groove 23 may be formed as a stepped groove so that a groove portion of the first groove 23 can support the diaphragm 30. The first groove 23 includes a first groove 231 and a second groove 233. In the first direction Z, the first slot 231 is farther from the housing 10 than the second slot 233. The first groove 231 is farther from the first through hole 101 than the second groove 233 in a direction parallel to the housing 10. The connector 40 is disposed in the first groove 231, and the diaphragm 30 is disposed in the second groove 233. The connection 40 supports a portion of the diaphragm 30. The bottom wall of the second groove 233 supports the portion of the diaphragm 30 corresponding to the circumferential side of the first groove 231, prevents the diaphragm 30 from being suspended at a side facing away from the housing 10, and improves the shock resistance of the housing assembly 100.

In one embodiment, the structural member 20 is attached to the housing 10 at the peripheral side of the first groove 231, and the structural member 20 and the membrane 30 support the housing 10 together, so as to avoid suspending the housing 10 and improve the shock resistance of the housing assembly 100.

It will be appreciated that in other embodiments, the structural member 20 may not contact the housing 10.

It will be appreciated that in other embodiments, the first slot 231 and the second slot 233 of the first recess 23 may also be coplanar toward the sidewalls of the first through hole 101, respectively. The connecting piece 40 and the diaphragm 30 are respectively accommodated in the first groove 23, and the end face of the diaphragm 30 facing the first through hole 101 is coplanar with the end face of the connecting piece 40 facing the first through hole 101.

The orthographic projection of the connecting piece 40 on the shell 10 along the first direction Z is located in the orthographic projection area of the diaphragm 30 on the shell 10 along the first direction Z, so that the connecting piece 40 can fully support the diaphragm 30, or the first groove 23 can be manufactured into a stepped groove, so that the connecting piece 40 and the groove wall of the first groove 23 jointly support the diaphragm 30, the diaphragm 30 is prevented from being suspended, the part of the shell 10 adhered with the diaphragm 30 is prevented from being suspended, and the shock resistance of the shell assembly 100 is improved.

The decoration 60 includes a support base 61 and a cover 63. The part of the structural member 20 passes through the first through hole 101 and is connected with the supporting seat 61 in a sealing manner. The structural member 20 and the support seat 61 are clamped on opposite sides of the housing 10, respectively. The structural member 20 is fixedly connected with the supporting seat 61 through the threaded connection of the fastener with the structural member 20 and the supporting seat 61 respectively. It will be appreciated that in other embodiments, the structural member 20 and the supporting seat 61 may be fixedly connected by other connection methods such as snap-fit. The support seat 61 is hermetically connected to the structural member 20 by a gasket, sealant, or the like, so that the functional member 50 is isolated from the outside of the case 10.

The support seat 61 is provided with a second through hole 21. The cover 63 is hermetically connected to the support base 61 and covers the second through hole 21. The cover 63 is transparent to expose the functional element 50.

It will be appreciated that in other embodiments, the trim piece 60 need not be in sealing engagement with the structural member 20 when the structural member 20 or the functional member 50 is provided with sealing capability. The decoration 60 may be omitted, and the structural member 20 is fixedly coupled to one side of the case 10 by adhesion.

It will be appreciated that in other embodiments, the front projection of one of the connector 40 and the diaphragm 30 onto the housing 10 along the first direction Z is not coincident with the front projection of the region 51 onto the housing 10 along the first direction Z, so that the thickness of the electronic device 200 may also be reduced. For example, as shown in fig. 4, in another embodiment, the housing assembly 100d differs from the housing assembly 100 shown in fig. 2 in that: a portion of the connecting member 40 is located in the first groove 23d, and a portion of the other connecting member 40 bonded to the diaphragm 30 and the diaphragm 30 are accommodated in the first groove 23d, and a portion of the connecting member 40 located on the peripheral side of the diaphragm 30 is bonded between the structural member 20d and the housing 10. The diaphragm 30 of the housing assembly 100 and the front projection of the region 51 onto the housing 10 in the first direction Z, respectively, do not coincide. The membrane 30 and the section 51 are not overlapped in the first direction Z, respectively, reducing the thickness of the housing assembly 100 d.

The connecting piece 40 is partially located outside the first groove 23d and is disposed between the structural member 20d and the housing 10, so as to prevent the housing 10 from being suspended at one side of the structural member 20d, and improve the shock resistance of the housing assembly 100 d.

As another example, as shown in fig. 5, in yet another embodiment, the housing assembly 100e differs from the housing assembly 100 shown in fig. 2 in that: the connecting member 40 is accommodated in the first groove 23e, and a part of the diaphragm 30 is adhered between the housing 10 and the connecting member 40, and the other part is positioned between the structural member 20e and the housing 10. The diaphragm 30 of the housing assembly 100e and the front projection of the region 51 onto the casing 10 in the first direction Z, respectively, do not coincide. The connector 40 and the section 51 are not overlapped in the first direction Z, respectively, reducing the thickness of the housing assembly 100 e.

When the housing 10 is of a non-transparent glass structure, the membrane 30 may be omitted. For example, as shown in fig. 6, in another embodiment, the housing assembly 100f differs from the housing assembly 100 shown in fig. 2 in that: the connector 40 of the housing assembly 100f is bonded between the shell 10 and the structural member 20 f. The connecting piece 40 is accommodated in the first groove 23f, and the orthographic projections of the connecting piece 40 and the area 51 on the housing 10 along the first direction Z are not overlapped. The connector 40 and the section 51 are not overlapped in the first direction Z, respectively, reducing the thickness of the housing assembly 100 f.

When the side of the functional element 50 facing the housing 10 is provided with a planar structure, the planar structure of the functional element 50 can be directly bonded to the housing 10. For example, in another embodiment, FIG. 7 shows a partial schematic view of the housing assembly 100g mounted to the shell 10. The functional element 50d is a nameplate structure, and the functional element 50d and the structural element of the housing assembly 100g are the same structure. The functional element 50d passes through the first through hole 101 and is exposed from the first through hole 101 to the housing 10. The functional element 50d is provided with a connecting surface 52 on the side facing the housing 10. The connection surface 52 has a planar structure. The attachment member 40 is bonded between the attachment surface 52 and the housing 10 such that the functional element 50 is directly attached to the housing 10. The region 51g of the functional element 50d has a planar structure and is bonded to the case 10. The region 51g of the projection region of the functional element 50d is located on the inner peripheral side of the connecting surface 52, but is not limited thereto.

It will be appreciated that in other embodiments, when the section 51g of the functional element 50g shown in fig. 7 is located on the outer peripheral side of the connection surface 52, the functional element 50g may be fixedly connected to the housing 10 by adhering the connection member 40 between the connection surface 52 and the housing 10, as long as the connection surface 52 meets the sealing dimension requirement along the width parallel to the connection member 40.

It will be appreciated that in other embodiments, the housing assembly 100g shown in fig. 7 may also include a diaphragm (not shown). One side of the diaphragm is adhered to the case 10, and the other side is adhered to the connector 40, and the other part is adhered to the region 51g of the functional element 50 g.

Referring to fig. 8, in another embodiment, a housing assembly 100h includes a housing 10, a structural member 20, and a connecting member 40a. The housing 10 is provided with a first through hole 101, and opposite sides of the structural member 20 are respectively provided with a first groove 23h and a second groove 25h. The functional component 50h is disposed on the structural component 20, and an orthographic projection of the functional component on the housing 10 along the first direction Z covers the first through hole 101. The connecting member 40a is bonded between the structural member 20h and the housing 10, and an orthographic projection of the connecting member 40a on the housing 10 in the first direction Z is located on an outer peripheral side of the first through hole 101, and on an inner peripheral side of an orthographic projection of the region 51h on the housing 10 in the first direction Z. The portion of the functional element 50h that is spaced from the structural element 20 by zero is a zone 51h. The second recess 25h accommodates the region 51h, avoids overlapping of the connection member 40a and the region 51h in the first direction Z, and reduces the thickness of the electronic device including the housing assembly 100 h. In the above-mentioned housing assembly 100 and the electronic device 200 including the housing assembly 100, the housing 10 is provided with the first groove 23, the connecting member 40 is at least partially accommodated in the first groove 23, the first groove 23 provides an accommodating space for the connecting member 40, so that the thickness of the portion of the housing 10 corresponding to the first groove 23 can be made to be the minimum thickness meeting the strength requirement, so as to reduce the thickness of the housing assembly 100 and the electronic device 200.

The housing 10 is further provided with a second groove 25, and the second groove 25 is used for accommodating the functional element 50, so as to provide an installation space for the functional element 50, so that the thickness of the portion of the housing 10 corresponding to the second groove 25 can be made to be the minimum thickness meeting the strength requirement, and the thickness of the housing assembly 100 and the electronic device 200 can be reduced.

The orthographic projections of the first groove 23 and the second groove 25 on the housing 10 along the first direction Z are not overlapped, so that the region 51 in the second groove 25 and the connecting piece 40 or the membrane 30 in the first groove 23 are not overlapped in the first direction Z, and the housing assembly 100 ensures sealing performance while reducing thickness. When the diaphragm 30 is omitted, the thickness of the housing assembly 100 and the electronic device 200 is further reduced.

The above embodiments are only for illustrating the technical solution of the present application and not for limiting, and although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solution of the present application may be modified or equivalently replaced without departing from the spirit and essence of the technical solution of the present application.
