Light that the flash light sent can shine to the quilt bat object evenly behind bearing structure and the even light structure, for being clapped the object light filling to make the flash light realize the light filling effect. External light is collected by the rear camera through the light-transmitting structure and the first supporting hole, so that the rear camera can achieve the shooting function.

In some possible implementations, the light transmissive structure is located on one side of the support structure; the orthographic projection of the light homogenizing structure on the supporting structure is not overlapped with the orthographic projection of the light transmitting structure on the supporting structure, the light homogenizing structure collects light rays emitted by the flash lamp in all directions and then uniformly irradiates the light rays forwards to a shot object to supplement light for the shot object, and the flash lamp can be protected while the light supplementing effect is realized; the light transmission structure is collected by the rear camera after transmitting light of external light, so that the rear camera can achieve the shooting function, and the light transmission structure can also protect the rear camera.

In some possible implementations, in a case that an orthographic projection of the light uniformizing structure on the support structure does not overlap with an orthographic projection of the light transmitting structure on the support structure, the housing assembly further includes an adhesive structure; the light-transmitting structure is fixed on the supporting structure through the bonding structure; the bonding structure is provided with a first opening part; in the first direction, the first opening part corresponds to the first support hole; the first direction is a thickness direction of the main body structure. The light-transmitting structure is fixed on the supporting structure through the bonding structure, the method is simple, and the stability of the assembly is improved; and the first opening part is formed in the bonding structure, so that the bonding structure is prevented from influencing the shooting function of the rear camera.

In some possible implementations, along the first direction, the first support hole penetrates through the light unifying structure; the light transmitting structure is fixed on one side of the light homogenizing structure, which is far away from the supporting structure; the first direction is a thickness direction of the main body structure. Even light structure and light-transmitting structure stromatolite set up in fretwork portion, and the light-transmitting structure exposes the outside, so, can protect even light structure isotructure through light-transmitting structure.

In some possible implementations, the light-transmitting structure covers the light-homogenizing structure along the first direction on the basis that the light-transmitting structure is fixed to a side of the light-homogenizing structure facing away from the supporting structure. Therefore, after the rear shell is combined with the display screen and the middle frame, the terminal equipment only exposes the light-transmitting structure of the shell assembly from a rear view, namely the exposed structure is single, and the appearance quality of the terminal equipment is improved.

In some possible implementations, the support structure further includes a stop portion; the limiting part is arranged on the fixing part and arranged around the light uniformizing structure. Set up spacing portion on fixed knot constructs, when carrying out the body construction with flash lampshade to fashionable, carry on spacingly to flash lampshade through spacing portion for flash lampshade is accurate sets up in the body construction. And the limiting part is arranged around the dodging structure, so that the alignment precision is further improved.

In some possible implementation manners, a first groove corresponding to the limiting part is arranged on one side of the main body structure facing the supporting structure, and the limiting part is located in the first groove. Therefore, after the rear shell is combined with the display screen and the middle frame, the terminal equipment only exposes the light-transmitting structure of the shell assembly from the rear view, namely the exposed structure is single, and the appearance quality of the terminal equipment is improved. Meanwhile, the limiting part is arranged in the first groove, the size of the shell assembly in the thickness direction of the main structure cannot be increased, and the shell assembly is light and thin.

In some possible implementations, in a case where the light-transmitting structure is fixed to a side of the light unifying structure facing away from the support structure, in the first direction, a surface of the light-transmitting structure facing away from the side of the light unifying structure is flush with a surface of the main body structure facing away from the side of the support structure. By the arrangement, the appearance quality of the terminal equipment can be further improved.

In some possible implementations, in a case where the light-transmissive structure is fixed to a side of the light unifying structure facing away from the support structure, the housing assembly further includes an adhesive structure made of a light-transmissive material; the light-transmitting structure is fixed on the light-homogenizing structure through the bonding structure; the adhesive structure includes a first opening portion; in the first direction, the first opening portion corresponds to the first support hole. The light-transmitting structure is fixed on the light-homogenizing structure through the bonding structure, the method is simple, and the stability of the assembly is improved; and set up first opening on adhesive structure, avoid adhesive structure to influence the shooting function of rearmounted camera. Meanwhile, the bonding structure is made of the light-transmitting material, so that light rays emitted by the dodging structure are not shielded, the light supplementing function of the flash lamp is not influenced, the area of the bonding structure is large, and the light-transmitting structure can be more firmly fixed on the dodging structure.

In some possible implementations, in a case where the light-transmitting structure is fixed to a side of the light unifying structure facing away from the support structure, the housing assembly further includes an adhesive structure; the light-transmitting structure is fixed on the light-homogenizing structure through the bonding structure; the bonding structure comprises a first opening part and a second opening part; in the first direction, the first opening part corresponds to the first support hole, and the second opening part corresponds to the light uniformizing structure. The light-transmitting structure is fixed on the light-homogenizing structure through the bonding structure, the method is simple, and the stability of the assembly is improved; and set up first opening on adhesive structure, avoid adhesive structure to influence the shooting function of rearmounted camera. In addition, the bonding structure further comprises a second opening part, and the second opening part corresponds to the light homogenizing structure, so that the bonding structure cannot shield light emitted by the light homogenizing structure, and further the light supplementing function of the flash lamp cannot be influenced. When the adhesive structure further includes the second opening portion, the material of the adhesive structure can be selected more flexibly, i.e. not only a light-transmitting material but also a non-light-transmitting material.

In some possible implementations, the first support hole penetrates through the light unifying structure along a first direction; a second groove is formed in the surface of one side, away from the supporting structure, of the light homogenizing structure; the light-transmitting structure is fixed in the second groove; the first direction is a thickness direction of the main body structure. So set up, when being fixed in the second recess that even light structure was seted up with light-transmitting structure, can improve counterpoint equipment precision. In addition, the light-transmitting structure is located in the second groove, and the light-homogenizing structure can be used for protecting the light-transmitting structure.

In some possible implementation manners, in the case that a second groove is formed in a side surface of the light uniformizing structure away from the support structure, the housing assembly further includes an adhesive structure; the light-transmitting structure is arranged in the second groove through the bonding structure; the bonding structure is provided with a first opening part; in the first direction, the first opening portion corresponds to the first support hole. The light-transmitting structure is fixed on the light-homogenizing structure through the bonding structure, the method is simple, and the stability of the assembly is improved; and set up first opening on adhesive structure, avoid adhesive structure to influence the shooting function of rearmounted camera. In addition, because the second groove can limit the flowing of glue, a glue dispensing process can be adopted when the bonding structure is formed. The bonding structure formed by the dispensing process can improve the bonding effect between the light-transmitting structure and the flash lampshade.

In some possible implementation modes, the supporting structure and the light homogenizing structure are integrally formed, so that the process steps are simplified, the supporting structure and the light homogenizing structure do not need to be bonded, and the preparation efficiency of the shell assembly is improved.

In some possible implementations, the support structure and the light homogenizing structure are formed separately, so that the material of the support structure can be selected more flexibly, for example, the material of the support structure may include not only PMMA material but also metal and the like.

In some possible implementations, the elastic modulus of the light transmissive structure is greater than the elastic modulus of the light unifying structure. Because the light-transmitting structure is high in hardness and not easy to wear, when the light-transmitting structure is made of a high-transmittance material, the high transmittance can be kept even if the light-transmitting structure is used for a long time, the transmittance of the light-transmitting structure cannot be influenced by scratching, and the light-transmitting requirement and the PV value requirement are met.

In some possible implementations, the material of the light-transmitting structure includes a material with high transmittance and high hardness such as glass or sapphire. Avoid because the printing opacity structure is used for a long time and is easily scraped the flower, and lead to the printing opacity structure transmissivity low, and then influence the shooting performance of rearmounted camera.

In some possible implementations, the shape of the hollowed-out portion includes a racetrack shape; the racetrack shape is the shape of a city surrounded by two arcs and two opposite sides of a rectangle, wherein the two arcs are arranged oppositely and are respectively adjacent to the two opposite sides. The shape of the hollow-out part can also comprise a track shape, a circle shape, a round square shape, a round rectangle shape and the like.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The term "and/or" herein is merely an association relationship describing an associated object, and means that there may be three relationships, for example, a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone.

The terms "first" and "second," and the like in the description and in the claims of the embodiments of the present application, are used for distinguishing between different objects and not for describing a particular order of the objects. For example, the first target object and the second target object, etc. are specific sequences for distinguishing different target objects, rather than describing target objects.

In the embodiments of the present application, words such as "exemplary" or "for example" are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "e.g.," is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

In the description of the embodiments of the present application, the meaning of "a plurality" means two or more unless otherwise specified. For example, a plurality of processing units refers to two or more processing units; the plurality of systems refers to two or more systems.

The embodiment of the application provides a terminal device, which can be an electronic device integrated with a rear-mounted flash lamp, a camera and other devices, such as a mobile phone, a tablet computer, a Personal Digital Assistant (PDA), a vehicle-mounted computer and the like. The embodiment of the present application does not limit the specific form of the electronic device. As shown in fig. 1, for convenience of description, the following description will be made by taking a mobile phone as an example of the terminal device.

As shown in fig. 1, the mobile phone includes a display screen 10, a rear case 20, and a middle frame 30 between the display screen 10 and the rear case 20. The display screen 10, the middle frame 30 and the rear case 20 may enclose an accommodation cavity. The accommodating cavity is internally provided with a flash lamp 40, a rear camera 50 and the like. The number of the rear cameras 50 may be one or more. When the number of the rear cameras 50 is plural, the functions of the plural rear cameras 50 may be different. For example, in one possible implementation, one of the rear cameras 50 is responsible for main shooting, one of the rear cameras 50 is responsible for zooming, one of the rear cameras 50 is responsible for wide-angle, one of the rear cameras 50 is responsible for macro, one of the rear cameras 50 is responsible for increasing the shooting focusing speed (e.g., time-of-flight camera), and the like.

For the convenience of clearly describing the following structural features and the positional relationship of the structural features, the positional relationship of the structures in the mobile phone is defined by the X-axis direction, the Y-axis direction and the Z-axis direction. The X-axis direction is the width direction of the mobile phone, the Y-axis direction is the length direction of the mobile phone, and the Z-axis direction (also called the first direction) is the thickness direction of the mobile phone.

Referring to fig. 2, the rear housing 20 includes a rear housing body 21 and a decoration 60, wherein the rear housing body 21 is opened with a decoration hole 211, and the decoration 60 is disposed at the decoration hole 211. The garnish 60 includes a garnish body 61, and in some embodiments, the garnish 60 may further include a structure for fixing the garnish body 61 to the rear case body 21.

As for the shape of the decoration hole 211, as shown in fig. 2, the shape of the decoration hole 211 may be, for example, a racetrack shape, a circular shape, a rounded square shape, a rounded rectangle, or the like, which is not limited in this embodiment of the application. It is understood that the racetrack shape may be: the two arcs are in a shape of a wall surrounding two opposite sides of a rectangle, wherein the two arcs are arranged oppositely, and the two arcs are respectively adjacent to the two opposite sides.

In order to solve the problems of the background art, in the related art, the rear housing body 21 or the decoration body 61 is made of a light-transmitting material, and light can transmit through the rear housing body 21 or the decoration body 61, so that the flash lamp 40 achieves a light supplementing effect, and the rear camera 50 achieves a shooting function.

However, in some terminal devices, the material of the rear case body 21 or the garnish body 61 may be a non-light-transmitting material. Illustratively, the material of the rear case body 21 or the garnish body 61 may include, for example, an opaque material such as plastic, a cellulose skin, or glass fiber. Because the non-light-transmitting material has a shielding effect on light, light emitted by the flash lamp 40 cannot be irradiated to the photographed object, and further light cannot be supplemented to the photographed object; the rear camera 50 cannot receive external light, and further cannot collect images, so that a shooting function is realized.

Based on this, the present application embodiment provides a housing component, which may be the rear housing 20 or the decoration 60 above. The following exemplifies the arrangement positions when the rear camera 50 and the flash 40 and the like are applied to the housing assembly.

In some possible implementations, with continued reference to fig. 2, the rear camera 50 includes at least one first rear camera 51. The rear case body 21 includes a light-transmitting region 212 and other regions 213. The flash 40 and the at least one first rear camera 51 are located in the light-transmitting area 212. The light emitted by the flash 40 can irradiate the object to be photographed after passing through the light-transmitting area 212 of the rear case body 21, so as to supplement light for the object to be photographed, i.e. the light supplement function is realized. The external light can be collected by the first rear camera 51 after passing through the light-transmitting region 212 of the rear housing body 21, so that the first rear camera 51 can realize the shooting function. In some embodiments, the plurality of rear cameras 50 may also include at least one second rear camera 52. The rear case body 21 has a region where the decoration hole 211 is located, in addition to the first region 212 and the other regions 213. At least one second rear camera 52 is located in the area where the decoration hole 211 is located, and outside light is collected by the second rear camera 52 after passing through the decoration body 61, so that the second rear camera 52 achieves a shooting function.

Here, when the number of the first rear cameras 51 is plural, the functions of the plural first rear cameras 51 may be the same or different. When the number of the second rear cameras 52 is plural, the functions of the plural second rear cameras 52 may be the same or different.

In other possible implementations, the number of the first rear camera 51 in the terminal device is one or more. The garnish body 61 may include the light-transmitting region 212 described above and other regions 213, wherein the other regions 213 may be, for example, regions other than the light-transmitting region 212. The strobe 40 and all of the first rear cameras 51 are located in the light-transmitting area 212. The light that flash light 40 sent can shine to the object of being clapped behind the light zone 212 of decoration body 61, for being clapped the object light filling to realize the light filling function. The external light can be collected by the first rear camera 51 after passing through the light-transmitting region 212 of the trim body 61, so that the first rear camera 51 can realize the shooting function.

It should be noted that the number of the rear cameras 50 and the positional relationship among the decoration 60, the flash 40 and the rear cameras 50 may be set according to actual situations, and this is not particularly limited in the embodiment of the present application.

As shown in fig. 3, the structure of the housing assembly will be described in detail below in conjunction with the terminal device. The housing assembly includes: main part structure, flash of light lamp shade and light-transmitting structure. It is understood that when the housing assembly is the rear case 20 of the terminal device, the main structure of the housing assembly is the rear case body 21 of the rear case 20. When the housing component is the garnish 60, the main structure in the housing component is the garnish body 61 of the garnish 60. Even if the material of the rear case body 21 or the decoration body 61 is a non-light-transmitting material, the housing assembly provided in the embodiment of the present application can also enable the flash 40 to realize a light supplementing function, and enable the rear camera 50 to realize a shooting function.

The specific structure of the housing assembly may be various, and the following description is made by using a typical example, and for more convenience and clarity of the following description, the following example describes the specific structure of the housing assembly by using the housing assembly as the rear housing 20 of the terminal device. The following does not limit the present application.

It is understood that when the housing component is the decoration 60, the specific structure of the decoration 60 and the effect thereof are the same as those of the following examples in which the housing component is the rear case 20, and detailed description of the specific structure when the housing component is the decoration 60 will not be provided below.

In one example, as shown in fig. 3 and 4, the housing assembly includes a body structure 21, a glare shield 22, and a light transmissive structure 25. The main body structure 21 is provided with a hollow portion 200. The hollow portion 200 is located in the light-transmitting area 212.

Referring to fig. 5a, the flashlight cover 22 includes a support structure 23 and a light unifying structure 24. The light unifying structure 24 is located at one side of the support structure 23. The support structure 23 includes a support portion 234 and a fixing portion 235 located at the periphery of the support portion 234. The supporting portion 234 defines at least one first supporting hole 2341. The first support hole 2341 penetrates the support portion 234 in the Z-axis direction. The flashlight cover 22 is fixed on the main body structure 21 through the fixing part 235; the light unifying structure 24 is located in at least a portion of the hollowed-out portion 200 in a direction in which the support structure 23 faces the main body structure 21. The light-transmitting structure 25 is also located at one side of the support structure 23. The light-transmitting structure 25 is located in at least a portion of the hollow portion 200, and the light-transmitting structure 25 covers the first support hole 2341.

With reference to fig. 5b, the support structure 23 comprises a first fixing area 231, a second fixing area 232 and a third fixing area 233. The first fixing region 231 is a region where an orthographic projection of the main body structure 21 on the support structure 23 overlaps the support structure 23, i.e., a region where the fixing portion 235 is located. The third fixing region 233 is a region of the support structure 23 including the first support hole 2341. The second fixing region 232 is a region of the support structure 23 other than the first fixing region 231 and the third fixing region 233. The supporting portion 234 is located at the second fixing region 232 and the third fixing region 233. The light unifying structure 24 is located at the second fixing area 232. The light-transmitting structure 25 is located at the third fixing region 233. In this way, the orthographic projection of the light unifying structure 24 on the support structure 23 does not overlap with the orthographic projection of the light transmissive structure 25 on the support structure 23.

Further, after the rear housing 20 is aligned with the display screen 10 and the middle frame 30, the first rear camera 51 and the flashlight 40 may be located on a side of the supporting structure 23 facing the display screen 10. Also, the first rear camera 51 is located at the third fixed area 233, and the flash 40 is located at the second fixed area 232.

It should be noted that, in some possible implementations, the supporting portion 234 is provided with a plurality of first supporting holes 2341, and the number of the first rear cameras 51 located in the third fixing area 233 may be the same as the number of the first supporting holes 2341. For example, referring to fig. 5b, the supporting portion 234 of the third fixing area 233 is provided with two first supporting holes 2341, and the number of the first rear cameras 51 of the third fixing area 233 may be two. In the Z-axis direction, one of the first support holes 2341 corresponds to one of the first rear cameras 51; another first supporting hole 2341 is connected to another first rear camera 51. That is, one of the first support holes 2341 covers an orthographic projection of one of the first rear cameras 51 on the support structure 23; the other first support hole 2341 covers an orthographic projection of the other first rear camera 51 on the support structure 23. In other words, in the Z-axis direction, one of the first support holes 2341 exposes one of the first rear cameras 51; the other first supporting hole 2341 exposes the other first rear camera 51.

In another possible implementation manner, referring to fig. 5d, the supporting portion 234 of the third fixing region 233 is formed with a first supporting hole 2341. One first support hole 2341 exposes one or more first rear cameras 51 in the Z-axis direction.

Here, the orthographic projection of the main body structure 21 on the support structure 23 may be a projection of the main body structure 21 on the support structure 23 along the Z-axis direction. The orthographic projection of the light unifying structure 24 on the support structure 23 may be a projection of the light unifying structure 24 on the support structure 23 along the Z-axis direction. The orthographic projection of the light-transmitting structure 25 on the support structure 23 may be a projection of the light-transmitting structure 25 on the support structure 23 along the Z-axis direction. The orthographic projection of the first rear camera 51 on the support structure 23 may be a projection of the first rear camera 51 on the support structure 23 along the Z-axis direction.

The material of the support structure 24 is not limited in the embodiments of the present application.

In some possible implementations, the material of the support structure 24 may include, for example, a light transmissive material. The light-transmitting material can transmit light, in other words, the light-transmitting material generally does not block the light from passing through. Exemplary materials for support structure 24 include, for example, plastic materials such as polymethyl Methacrylate (PMMA). In this way, the light emitted by the flash 40 can uniformly irradiate the object to be photographed through the transparent supporting structure 23 and the light-homogenizing structure 24, so as to supplement light for the object to be photographed, and thus the flash 40 can supplement light. External light is collected by the first rear camera 51 through the light-transmitting structure 25 and the first support hole 2341, so that the first rear camera 51 realizes the shooting function thereof.

In other possible implementations, the material of the support structure 24 may include, for example, a non-light-transmissive material. Illustratively, the material of the support structure 24 includes a non-light-transmitting material such as a metal, for example. Because the non-light-transmitting material shields light, the light emitted by the flash lamp 40 cannot irradiate the object to be photographed, and further, the light cannot be supplemented to the object to be photographed. In this case, the supporting portion 234 may further have at least one second supporting hole 2342, and the at least one second supporting hole 2342 is located in the second fixing area 232. In this way, the light emitted by the flash 40 can uniformly irradiate the object to be photographed through the second supporting hole 2342 and the light-homogenizing structure 24, so as to supplement light for the object to be photographed, and thus the flash 40 can supplement light. External light is collected by the first rear camera 51 through the light-transmitting structure 25 and the first support hole 2341, so that the first rear camera 51 realizes the shooting function thereof. In fig. 5a, fig. 5b, and fig. 5c, the material of the supporting structure 24 is a non-light-transmitting material, that is, the supporting portion 234 has a second supporting hole 2342 at a position located in the second fixing area 232.

It can be seen that, even if the material of the main body structure 21 is a non-light-transmitting material, the housing assembly in this example can implement the light supplement function of the flash 40, and enable the first rear camera 51 to implement the shooting function. On the basis, the flash lamp 40 can be protected by the light homogenizing structure 24, and the first rear camera 51 can be protected by the light transmitting structure 25.

In some possible implementations, in the Z-axis direction, the surface of the dodging structure 24 on the side facing away from the flash 40 and the surface of the light-transmitting structure 25 on the side facing away from the first rear camera 51 are both flush with the surface of the main body structure 21 on the side facing away from the flash 40. In this way, after the rear shell 20 is aligned with the display screen 10 and the middle frame 30, the appearance quality of the terminal device is improved when viewed from the rear.

As for the material of the light uniformizing structure 24, the embodiment of the present application is not particularly limited thereto, and any material may be used as long as it is a light uniformizing material. The dodging material is a material which can converge light rays in any direction and then uniformly emit the light rays forwards. For example, the material of the light unifying structure 24 may include a plastic material such as PMMA. Further, for example, fresnel characteristics having a light uniformizing effect may be formed on the light uniformizing structure 24. The fresnel pattern features with the light homogenizing effect can be formed, for example, by an injection molding process. Further, the elastic modulus of the light unifying structure 24 is, for example, 3GPa or less. For example 2GPa or 3 GPa.

As for the material of the light-transmitting structure 25, the material of the light-transmitting structure 25 is not limited in the embodiments of the present application. As long as it is a light-transmitting material. The light-transmitting material can transmit light, in other words, the light-transmitting material generally does not block the light from passing through. In addition, the light-transmitting structure 25 is also relatively rigid. When the material of the light-transmitting structure 25 is a material with a high transmittance, the light-transmitting structure 25 has high hardness and is wear-resistant, and after long-term use, the light-transmitting structure 25 can also have a high transmittance and a low peak-to-valley (PV) value. In some possible implementations, the light transmission rate of the light-transmitting structure 25 is, for example, greater than or equal to 93%, the mohs hardness thereof is greater than or equal to 6, the PV value < 1.3 λ and the elastic modulus thereof is greater than or equal to 50GPa during the life cycle. For example, 50GPa, 60GPa or 72 GPa. Illustratively, the material of the light-transmitting structure 25 may include glass, sapphire lens, and the like. Because light-transmitting structure 25 hardness is big, difficult wearing and tearing, therefore light-transmitting structure 25 can keep high transmissivity, even if light-transmitting structure 25 uses for a long time, still can satisfy printing opacity requirement and PV value requirement. It can be avoided that when the material of the light-transmitting structure 25 is the same as the material (for example, a plastic material) of the light-homogenizing structure 24, the transmittance of the light-transmitting structure 25 is low due to the scratch of the light-transmitting structure 25 after long-term use, and further the shooting performance of the first rear camera 51 is affected.

In addition, the shape of the hollow portion 200 may be designed into any shape based on design requirements, which is not limited in the embodiments of the present application. For example, the shape of the hollow portion 200 is, for example, a racetrack shape, a circular shape, a rounded square shape, a rounded rectangle shape, and the like, wherein all embodiments of the present application are described by taking the shape of the hollow portion 200 as the racetrack shape as an example.

In addition, in the present application, the supporting structure 23 and the light unifying structure 24 of the flashlight cover 22 may be formed separately or integrally.

The support structure 23 and the light unifying structure 24 are separately formed and integrally formed as described in detail below.

With continued reference to fig. 5a, fig. 5a illustrates an example in which the support structure 23 and the light unifying structure 24 are separately molded. The support structure 23 and the light unifying structure 24 are separately formed, so that the material of the support structure 23 can be selected more flexibly, for example, the material of the support structure 23 may include not only PMMA material but also metal, etc.

In addition, the assembly method between the main body structure 21 of the housing assembly, the support structure 23 of the flashlight cover 22, the light homogenizing structure 24 and the light transmitting structure 25 is not limited in this embodiment.

For example, with continued reference to fig. 5c, in some possible implementations, a layer connection 26 may be first provided on the support structure 23. The connecting structure 26 is not only located at the first fastening region 231 but also at the second fastening region 232. When the connecting structure 26 is arranged, the second supporting hole 2342 needs to be avoided, and the connecting structure 26 is prevented from shielding light emitted by the flash lamp 40 after the rear shell 20 is combined with the display screen 10 and the middle frame 30, so that the object to be shot cannot be irradiated.

The light unifying structure 24 is then fixed to the support structure 23 through the connecting structure 26 while covering the second support hole 2342 with the light unifying structure 24. An adhesive structure 27 is then provided on the support structure 23, the adhesive structure 27 and the connecting structure 26 being located on the same side of the support structure 23, and the adhesive structure 27 being located at the third fixing area 233. It can be understood here that, in order to avoid the adhesive structure 27 from affecting the shooting function of the first rear camera 51, the adhesive structure 27 is provided with a first opening 271. The first opening 271 corresponds to the first support hole 2341 in the Z-axis direction, that is, an orthographic projection of the first opening 271 on the support structure 23 covers the first support hole 2341, that is, the first opening 271 exposes the first support hole 2341 in the Z-axis direction. After the adhesive structure 27 is disposed, the main structure 21 and the flashlight cover 22 can be aligned, the supporting structure 23 of the flashlight cover 22 is fixed on the first surface of the main structure 21 through the connecting structure 26 on the fixing portion 235, and the light homogenizing structure 24 is located in the hollow portion 200.

Of course, the support structure 23 may be fixed to the first surface of the main body structure 21 by the connecting structure 26 on the fixing portion 235, and then the adhesive structure 27 may be provided on the support structure 23.

Here, the orthographic projection of the first opening 271 on the support structure 23 may be a projection of the first opening 271 on the support structure 23 along the Z-axis direction.

Here, it should be further noted that the first surface is: after the rear shell 20 is aligned with the display screen 10 and the middle frame 30, the main body structure 21 is close to the surface of one side of the display screen 10. The first surface described below is also a surface of the main structure 21 close to the display screen 10 after the rear housing 20 is aligned and combined with the display screen 10 and the middle frame 30, and is not described in detail below.

Next, the light-transmitting structure 25 is fixed on the supporting structure 23 by the adhesive structure 27, and is located in the third fixing region 233 and at least a portion of the hollow portion 200, and covers the first supporting hole 2341. Thus, the light-transmitting structure 25 and the light-homogenizing structure 24 are both located in the hollow portion 200. After the rear housing 20 is aligned with the display screen 10 and the middle frame 30, the terminal device only exposes the light-transmitting structure 25 and the light-homogenizing structure 24 of the housing assembly from a rear view.

For another example, in some possible implementations, a layer connecting structure 26 may be provided on the support structure 23. The connecting structure 26 is provided not only at the first fixing region 231 but also at the second fixing region 232 and the third fixing region 233. When the connecting structure 26 is arranged, the first supporting hole 2341 and the second supporting hole 2342 need to be avoided, and the connecting structure 26 is prevented from shielding light emitted by the flash lamp 40, so that the light cannot irradiate the shot object; and prevent the connection structure 26 from shielding external light, so that the first rear camera 51 cannot receive external light, and thus cannot collect an image. The light unifying structure 24 is then fixed on the supporting structure 23 through the connecting structure 26 and located in the second fixing area 232 while covering the second supporting hole 2342. After the light homogenizing structure 24 is arranged, the main body structure 21 and the flashlight cover 22 can be jointed. The supporting structure 23 is fixed on the first surface of the main structure 21 through the connecting structure 26 on the fixing portion 235, and the light uniformizing structure 24 is located in a portion of the hollow portion 200.

Of course, the light homogenizing structure 24 may be fixed on the supporting structure 23 by the connecting structure 26 located at the second fixing region 232 after the supporting structure 23 is fixed on the first surface of the main body structure 21 by the connecting structure 26 located at the fixing portion 235.

Next, the light-transmitting structure 25 is fixed on the supporting structure 23 through the connecting structure 26 and located in the third fixing region 233, covering the first supporting hole 2341.

Of course, after the supporting structure 23 is fixed on the first surface of the main body structure 21 by the connecting structure 26 on the fixing portion 235, the light-transmitting structure 25 can be fixed on the supporting structure 23 by the connecting structure 26, and then the light-homogenizing structure 24 can be fixed on the supporting structure 23 by the connecting structure 26. Thus, the light-transmitting structure 25 and the light-homogenizing structure 24 are both located in the hollow portion 200.

As another example, in some possible implementations, a ring of connecting structures 26 may be provided on the support structure 23. The connecting structure 26 is located at the first fixing area 231. An adhesive structure 27 is then provided on the support structure 23. The adhesive structure 27 is located on the same side of the support structure 23 as the attachment structure 26, and the adhesive structure 27 is arranged at the second and

third fastening areas

232, 233. When the bonding structure 27 is arranged, the first supporting hole 2341 and the second supporting hole 2342 need to be avoided, and the bonding structure 27 is prevented from shielding light emitted by the flash lamp 40 and being incapable of irradiating the shot object; and to avoid the bonding structure 27 from shielding the external light, so that the first rear camera 51 cannot receive the external light, and further cannot collect the image. After the adhesive structure 27 is provided, the body structure 21 and the flashlight cover 22 may be mated. The support structure 23 is secured to the first face of the body structure 21 by the attachment structure 26 on the securing portion 235. The adhesive structure 27 is now exposed through the hollowed-out portion 200. The light unifying structure 24 is then fixed on the support structure 23 by the adhesive structure 27 and located at the second fixing region 232, so that the light unifying structure 24 is located in a portion in the hollow portion 200. Next, the light-transmitting structure 25 is fixed on the supporting structure 23 by the adhesive structure 27 and located in the third fixing region 233, so that the light-transmitting structure 25 is located in a portion of the hollow portion 200.

Of course, the light-transmitting structure 25 may be fixed on the supporting structure 23 by the adhesive structure 27 and located in the third fixing region 233, so that the light-transmitting structure 25 is located in the hollow portion 200. Next, the light unifying structure 24 is fixed on the supporting structure 23 through the adhesive structure 27 and located in the second fixing area 232, so that the light unifying structure 24 is located in a portion of the hollow portion 200.

Referring to fig. 6a and 6b, it can be seen from fig. 6a and 6b that the support structure 23 and the light homogenizing structure 24 are integrally formed, that is, the flash cover 22 is integrally formed. When the flash cover 22 is integrally formed, the process steps are simplified, the bonding of the supporting structure 23 and the light uniformizing structure 24 is not required, and the manufacturing efficiency of the housing assembly is improved.

In addition, the assembly method among the main body structure 21 of the housing assembly, the flashlight cover 22 and the light-transmitting structure 25 is not limited in this embodiment.

For example, referring to fig. 6c, in some possible implementations, a ring of connecting structures 26 may be provided on the fixing portion 235. A layer of adhesive structure 27 is then provided on the support 234 at the third fixing area 233. The light unifying structure 24, the adhesive structure 27 and the connecting structure 26 are located on the same side of the support structure 23. In order to avoid the adhesive structure 27 from affecting the shooting function of the first rear camera 51, the adhesive structure 27 is provided with a first opening 271. The first opening 271 corresponds to the first support hole 2341 in the Z-axis direction, that is, an orthographic projection of the first opening 271 on the support structure 23 covers the first support hole 2341, that is, the first opening 271 exposes the first support hole 2341 in the Z-axis direction. After the adhesive structure 27 is provided, the body structure 21 and the flashlight cover 22 may be mated. The glare shield 22 is fixed to the first surface of the main body structure 21 by the connection structure 26 on the fixing portion 235 so that the light uniforming structure 24 is located in a portion in the hollow portion 200. Next, the light-transmitting structure 25 is fixed on the supporting structure 23 by the adhesive structure 27 and located in the third fixing region 233, so that the light-transmitting structure 25 is located in a portion of the hollow portion 200. Thus, the light-transmitting structure 25 and the light-homogenizing structure 24 are both located in the hollow portion 200.

The materials of the connecting structure 26 and the adhesive structure 27 are not limited in this embodiment. Illustratively, the material of the connecting structure 26 and the adhesive structure 27 may include, for example, double-sided tape.

In addition, with continued reference to fig. 5b and 6b, the present embodiment does not specifically limit the size and shape of the fixing portion 235. The retainer 235 at the periphery of the support 234 includes a first annular edge 2351 and a second annular edge 2352. The first annular edge 2351 is an edge in contact with the support 234; the second annular edge 2352 is an edge 2352 located on a side of the first annular edge 2351 facing away from the support 234. Wherein the closest distance from any point on the first annular edge 2351 to the second annular edge 2352 is the dimension W1 of the retainer portion 235. The larger the dimension W1 of the fixing portion 235, the larger the area of the connecting structure 26 on the fixing portion 235, and the more fully the flashlight cover 22 is fixed to the main body structure 21 by the connecting structure 26. Of course, in practical applications, the dimension W1 of the fixing portion 235 may not be infinite. In some possible implementations, the dimension W1 of the fixation portion 235 may be greater than or equal to 0.6mm, less than or equal to 2mm, for example. For example, the dimension W1 of the fixation portion 235 may be 1.42 mm. Thus, the size W1 of the fixing portion 235 is not too large, which does not occupy too much internal space of the terminal device, and the size W1 of the fixing portion 235 is not too small, which does not cause the flashlight cover 22 and the main body structure 21 to be fixed firmly.

It should be noted here that the support structure 23 and the light homogenizing structure 24 of the flashlight cover 22 in the following examples may be formed separately or integrally. The following description will be made by taking the support structure 23 and the light uniformizing structure 24 as an example.

It should be noted that the housing assembly in the above example is not only suitable for the main body structure 21 to be made of a non-light-transmitting material, but also suitable for the main body structure 21 to be made of a light-transmitting material. The housing assembly of the following example is not only suitable for the main structure 21 to be made of a non-light-transmitting material, but also suitable for the main structure 21 to be made of a light-transmitting material, and the following example is not repeated.

In yet another example, as shown in fig. 7, 8 and 9, unlike the previous example: the dodging structure 24 in this example is located not only at the second fixed region 232 but also at the third fixed region 233. The first support hole 2341 penetrates the light unifying structure 24 located at the third fixing area 233 in the Z-axis direction. Optionally, the light homogenizing structure 24 located at the second fixing region 232 is, for example, a fresnel feature with a light homogenizing effect.

In addition, the position of the light-transmitting structure 25 in the present example is also changed accordingly as compared with the above example. Specifically, the light-transmitting structure 25 is disposed on a side of the light unifying structure 24 away from the support structure 23, that is, the light unifying structure 24 is located between the light-transmitting structure 25 and the support structure 23. The light-transmitting structure 25 is located in the second fixing region 232 and the third fixing region 233. In the Z-axis direction, the light uniformizing structure 24 and the light transmitting structure 25 are stacked and embedded in the hollow portion 200.

In this way, after the rear shell 20 is aligned with the display screen 10 and the middle frame 30, the light emitted by the flash 40 can uniformly irradiate the object to be photographed through the supporting structure 23, the light-homogenizing structure 24 and the light-transmitting structure 25, so as to supplement light for the object to be photographed, and thus the flash 40 can supplement light. External light is collected by the first rear camera 51 through the light-transmitting structure 25 and the first support hole 2341, so that the first rear camera 51 realizes the shooting function thereof. That is, the housing assembly in this example can realize the light supplement function of the flash 40 and the photographing function of the second rear camera 50. On this basis, the light-transmitting structure 25 covers the light uniformizing structure 24 along the Z-axis direction. Because the light homogenizing structure 24 and the light transmitting structure 25 are stacked and embedded in the hollow portion 200, and the light transmitting structure 25 is disposed on a side of the light homogenizing structure 24 away from the supporting structure 23, after the rear shell 20 is closed with the display screen 10 and the middle frame 30, the terminal device is only exposed out of the light transmitting structure 25 of the housing assembly when viewed from the rear view, that is, the exposed structure is single, and the appearance quality of the terminal device is improved. In addition, since the light-transmitting structure 25 is exposed to the outside, the structure such as the light uniformizing structure 24 can be protected by the light-transmitting structure 25; and because the exposed light-transmitting structure 25 has high hardness and high transmittance, the light-transmitting requirement and the PV value requirement can be met even if the light-transmitting structure 25 is used for a long time.

In some possible implementations, in the Z-axis direction, a surface of the light unifying structure 24 on a side facing away from the support structure 23 is lower than a surface of the main body structure 21 on a side facing away from the support structure 23, and a surface of the light transmitting structure 25 on a side facing away from the support structure 23 is flush with a surface of the main body structure 21 on a side facing away from the support structure 23. By the arrangement, the appearance quality of the terminal equipment can be further improved.

The assembly method among the main body structure 21 of the housing assembly, the flashlight cover 22 and the light-transmitting structure 25 is not limited in this embodiment.

For example, referring to fig. 10, in some possible implementations, a ring of the connecting structure 26 may be provided on the fixing portion 235. A layer of adhesive structures 27 is then provided on the side of the light unifying structure 24 facing away from the support structure 23, wherein the adhesive structures 27 are located at the second and third fixing

areas

232, 233 for example. In order to avoid that the bonding structure 27 shields the external light after the subsequent alignment, so that the first rear camera 51 cannot receive the external light and further cannot collect an image, the bonding structure 27 located in the third fixing area 233 is provided with a first opening 271. The first opening 271 corresponds to the first support hole 2341 in the Z-axis direction, that is, an orthographic projection of the first opening 271 on the support structure 23 covers the first support hole 2341, that is, the first opening 271 exposes the first support hole 2341 in the Z-axis direction. In addition, in order to prevent the adhesive structure 27 from blocking the light emitted from the flash 40 after the rear case 20 is aligned with the display screen 10 and the middle frame 30, and thus the light cannot be irradiated to the object, the adhesive structure 27 located in the second fixing area 232 is provided with a second opening 272. The portion of the light unifying structure 24 having the fresnel character is exposed through the second opening portion 272. After the adhesive structure 27 is provided, the body structure 21 and the flashlight cover 22 may be mated. The flashlight cover 22 is fixed on the first surface of the main body structure 21 through the connecting structure 26 on the fixing portion 235, and the light homogenizing structure 24 is located in the hollow portion 200.

Of course, after the flashlight cover 22 is fixed to the first surface of the main body structure 21 by the connecting structure 26 on the fixing portion 235, a layer of adhesive structure 27 may be disposed on the side of the light uniforming structure 24 away from the supporting structure 23.

Next, the light-transmitting structure 25 is fixed on the light uniformizing structure 24 by the adhesive structure 27. The light-transmitting structure 25 is located in the second fixing region 232 and the third fixing region 233. In this way, the light uniformizing structure 24 and the light transmitting structure 25 are stacked and embedded in the hollow portion 200 in the Z-axis direction. When the rear housing 20 is aligned with the display screen 10 and the middle frame 30, the terminal device only exposes the light-transmitting structure 25 of the housing assembly when viewed from the rear.

It should be noted here that the material of the bonding structure 27 may include a non-light-transmitting material or a light-transmitting material. The foregoing has defined light transmissive materials and will not be described in detail herein. With continued reference to fig. 10, when the material of the adhesive structure 27 includes a non-light-transmitting material, the adhesive structure 27 needs to be provided with a second opening 272 in the second fixing region 232. Alternatively, referring to fig. 11, when the material of the adhesive structure 27 may include a light-transmitting material, for example, the adhesive structure 27 does not need to open the second opening 272 in the second fixing region 232. When the second opening 272 is not formed in the bonding structure 27, the area of the bonding structure 27 is increased, and the light-transmitting structure 25 can be more firmly fixed on the light-homogenizing structure 24. When the material of the adhesive structure 27 includes a transparent material, the material of the adhesive structure 27 may include Optically Clear Adhesive (OCA), for example.

In another example, as shown in fig. 12 and 14, unlike the previous example: the support structure 23 further includes a stop 236; the position-limiting portion 236 is disposed on the fixing portion 235 and surrounds the light-homogenizing structure 24. In one possible implementation manner, in the Z-axis direction, the surface of the side of the dodging structure 24 facing away from the support structure 23 is lower than the surface of the side of the limiting portion 236 facing away from the support structure 23.

Carry on spacingly to the flash lampshade 22 through setting up spacing portion 236 for when carrying out the counterpoint with the major structure 21 with the flash lampshade 22, can carry on spacingly to the flash lampshade 22 through spacing portion 236, make the accurate setting on the major structure 21 of flash lampshade 22. Further, the limiting part 236 is disposed around the light uniformizing structure 24, so as to further improve the alignment precision.

It should be noted that, in the present embodiment, the specific position of the limiting portion 236 on the fixing portion 235 is not limited. As long as the flashlight cover 22 can be limited.

In one possible implementation, referring to fig. 14, an orthographic projection of the limiting portion 236 on the supporting structure 23 is located at an outer circle of an orthographic projection of the hollow portion 200 on the supporting structure 23, that is, the limiting portion 236 is located at an edge of the fixing portion 235. Thus, the limiting portion 236 not only limits the flashlight cover 22, but also accurately sets the flashlight cover 22 on the main body structure 21. When the light-transmitting structure 25 is fixed in the limiting portion 236, the alignment and assembly accuracy of the light-transmitting structure 25 can be improved.

In one possible implementation, referring to fig. 17, the position-limiting portion 236 may also be located at a non-edge region of the fixing portion 235, for example, at a middle region of the fixing portion 235.

In one possible implementation, referring to fig. 13, the main body structure 21 is provided with a first groove 210 corresponding to the position-limiting portion 236 on a side facing the support structure 23, and the position-limiting portion 236 is located in the first groove 210. Thus, after the rear housing 20 is aligned with the display screen 10 and the middle frame 30, the terminal device only exposes the light-transmitting structure 25 of the housing assembly from a rear view, that is, the exposed structure is single, thereby improving the appearance quality of the terminal device.

In the present embodiment, the assembly manner among the main body structure 21 of the housing assembly, the flashlight cover 22 and the light-transmitting structure 25 is not limited in the present embodiment. Referring to fig. 16, for example, the assembling method may be the same as that of the above embodiment, and specifically, the assembling method of the above embodiment may be referred to, and is not described herein again.

When the light-transmitting structure 25 is disposed on the light unifying structure 24, for example, a layer of adhesive structure 27 may be disposed on the light unifying structure 24, and the light-transmitting structure 25 is fixed on the light unifying structure 24 through the adhesive structure 27. As in the above embodiment, in order to avoid that the bonding structure 27 blocks the external light after the subsequent alignment, and the first rear camera 51 cannot receive the external light, and thus cannot collect an image, the bonding structure 27 located in the third fixing area 233 is provided with a first opening 271. The first opening 271 corresponds to the first support hole 2341 in the Z-axis direction, that is, an orthographic projection of the first opening 271 on the support structure 23 covers the first support hole 2341, that is, the first opening 271 exposes the first support hole 2341 in the Z-axis direction. In order to prevent the adhesive structure 27 from shielding the light emitted from the flash 40 after the rear housing 20 is combined with the display screen 10 and the middle frame 30, and thus the light cannot be irradiated to the object to be photographed, the adhesive structure 27 located in the second fixing area 232 is provided with a second opening 272. The portion of the light unifying structure 24 having the fresnel character is exposed through the second opening portion 272.

It should be noted here that the material of the bonding structure 27 may include a non-light-transmitting material or a light-transmitting material. The foregoing has defined light transmissive materials, and the description thereof is omitted here. With continued reference to fig. 16, when the material of the adhesive structure 27 includes a non-light-transmitting material, the adhesive structure 27 needs to be provided with a second opening 272 in the second fixing region 232. Alternatively, when the material of the adhesive structure 27 may include a light-transmitting material, for example, in this case, the adhesive structure 27 does not need to open the second opening 272 (not shown in the figure) in the second fixing region 232. When the second opening portion 272 is not formed in the bonding structure 27, the arrangement area of the bonding structure 27 is increased, and the light-transmitting structure 25 can be more firmly fixed on the light uniforming structure 24. When the material of the adhesive structure 27 includes a transparent material, the material of the adhesive structure 27 may include an Optically Clear Adhesive (OCA), for example.

In yet another example, as shown in fig. 18, 19 and 20, the light unifying structure 24 in this example is located not only at the second fixing area 232 but also at the third fixing area 233. The difference from the previous example is: the light homogenizing structure 24 located in the second fixing region 232 and the third fixing region 233 is provided with a second groove 241 on a side away from the flash 40, and the second groove 241 is located in the second fixing region 232 and the third fixing region 233. The light uniformizing structure 24 is embedded in the hollow portion 200, and the light transmitting structure 25 is located in the second groove 241. After the rear shell 20 is combined with the display screen 10 and the middle frame 30, light emitted by the flash lamp 40 can uniformly irradiate the object to be photographed through the supporting structure 23, the light-homogenizing structure 24 and the light-transmitting structure 25, so as to supplement light for the object to be photographed, and thus the flash lamp 40 can supplement light. External light is collected by the first rear camera 51 through the light-transmitting structure 25 and the first support hole 2341, so that the first rear camera 51 realizes the shooting function thereof. That is, even if the material of the main body structure 21 is a non-light-transmitting material, the housing assembly in this example can implement the light supplement function of the flash 40 and the shooting function of the second rear camera 50. In addition, since the second groove 241 is formed on the light uniformizing structure 24, the alignment and assembly accuracy can be improved when the light transmitting structure 25 is fixed in the second groove 241. In addition, the light-transmitting structure 25 is located in the second groove 241, and the light-homogenizing structure 24 can be used for protecting the light-transmitting structure 25.

In some possible implementations, in the Z-axis direction, the surface of the side of the light uniforming structure 24 facing away from the flash lamp 40 is flush with the surface of the side of the main body structure 21 facing away from the flash lamp 40, and the surface of the side of the light-transmitting structure 25 facing away from the flash lamp 40 is also flush with the surface of the side of the main body structure 21 facing away from the flash lamp 40. So set up, can promote this terminal equipment's outward appearance quality.

For example, referring to fig. 21, in some possible implementations, a ring of connecting structures 26 may be provided on the fixing portion 235. After the connection structure 26 is disposed, the main body structure 21 and the flashlight cover 22 can be closed, the flashlight cover 22 is fixed on the first surface of the main body structure 21 through the connection structure 26 on the fixing portion 235, and the light homogenizing structure 24 is located in the hollow portion 200. An adhesive structure 27 is then provided within the groove 241. Since the groove 241 may restrict the flow of glue, an adhesive structure 27 may be provided within the groove 241 by a glue dispensing process, wherein the adhesive structure 27 is located at the second and third fixing

areas

232, 233, for example. In order to prevent the bonding structure 27 from shielding external light after the rear housing 20 is combined with the display screen 10 and the middle frame 30, and thus the first rear camera 51 cannot receive the external light and further cannot collect images, the bonding structure 27 located in the third fixing area 233 is provided with a first opening 271. The first opening 271 corresponds to the first support hole 2341 in the Z-axis direction, that is, an orthographic projection of the first opening 271 on the support structure 23 covers the first support hole 2341, that is, the first opening 271 exposes the first support hole 2341 in the Z-axis direction. In addition, in order to prevent the adhesive structure 27 from blocking the light emitted from the flash 40 and preventing the light from being irradiated to the object after the rear case 20 is aligned with the display screen 10 and the middle frame 30, the adhesive structure 27 located in the second fixing region 232 is opened with a second opening 272. The portion of the light unifying structure 24 having the fresnel character is exposed through the second opening portion 272. Next, the light-transmitting structure 25 is fixed in the groove 241 through the adhesive structure 27 and located in the second fixing region 232 and the third fixing region 233. Thus, after the rear housing 20 is aligned and combined with the display screen 10 and the middle frame 30, the terminal device exposes the light-transmitting structure 25 and the light-homogenizing structure 24 of the housing assembly, and the light-homogenizing structure 24 surrounds the light-transmitting structure 25 when viewed from the rear.

It is understood that the adhesive structure 27 is provided by a dispensing process, so as to improve the adhesion effect between the light-transmitting structure 25 and the flashlight cover 22.

It should be noted here that the material of the bonding structure 27 may include a non-light-transmitting material or a light-transmitting material. The foregoing has defined light transmissive materials, and the description thereof is omitted here. With continued reference to fig. 21, when the material of the adhesive structure 27 includes a non-light-transmitting material, the adhesive structure 27 needs to be provided with a second opening 272 in the second fixing region 232. Alternatively, when the material of the adhesive structure 27 may include a light-transmitting material, for example, in this case, the adhesive structure 27 does not need to open the second opening 272 (not shown in the figure) in the second fixing region 232. When the second opening 272 is not formed in the bonding structure 27, the area of the bonding structure 27 is increased, and the light-transmitting structure 25 can be more firmly fixed on the light-homogenizing structure 24. When the material of the adhesive structure 27 includes a transparent material, the material of the adhesive structure 27 may include an Optically Clear Adhesive (OCA), for example.

In still another example, as shown in fig. 22, 23, and 24, unlike the previous example: the second groove 241 is located only at the third fixing region 233. The light-homogenizing structure 24 is embedded in the hollow portion 200, and the light-transmitting structure 25 is located in the second groove 241. In this way, after the rear shell 20 is aligned with the display screen 10 and the middle frame 30, the light emitted by the flash 40 can uniformly irradiate the object to be photographed through the supporting structure 23, the light-homogenizing structure 24 and the light-transmitting structure 25, so as to supplement light for the object to be photographed, and thus the flash 40 can supplement light. External light is collected by the first rear camera 51 through the light-transmitting structure 25 and the first support hole 2341, so that the first rear camera 51 realizes the shooting function thereof. That is, even if the material of the main body structure 21 is a non-light-transmitting material, the housing assembly in this example can implement the light supplement function of the flash 40 and implement the shooting function of the second rear camera 50. On the basis, the second groove 241 is formed on the light uniformizing structure 24. Therefore, when the light-transmitting structure 25 is fixed in the second groove 241, the alignment and assembly accuracy can be improved. In addition, when the light-transmitting structure 25 is located in the second groove 241, the light-homogenizing structure 24 can be used to protect the light-transmitting structure 25.

In one possible implementation manner, in the Z-axis direction, a surface of a side wall of the second groove 241 facing away from the flash lamp 40 is flush with a surface of a side of the main body structure 21 facing away from the flash lamp 40, and a surface of the light-transmitting structure 25 facing away from the flash lamp 40 is also flush with a surface of a side of the main body structure 21 facing away from the flash lamp 40. By the arrangement, the appearance quality of the terminal equipment can be further improved.

For example, referring to fig. 25, in some possible implementations, a ring of connecting structures 26 may be provided on the fixing portion 235. After the connection structure 26 is disposed, the main body structure 21 and the flashlight cover 22 can be closed, the flashlight cover 22 is fixed on the first surface of the main body structure 21 through the connection structure 26 on the fixing portion 235, and the light homogenizing structure 24 is located in the hollow portion 200. An adhesive structure 27 is then provided within the second recess 241. Since the second groove 241 may limit the flow of glue, an adhesive structure 27 may be provided within the second groove 241 by a dispensing process, wherein the adhesive structure 27 is located at the third fixing area 233, for example. In order to avoid that the bonding structure 27 blocks the external light after the subsequent folding, so that the first rear camera 51 cannot receive the external light and further cannot collect an image, the bonding structure 27 located in the third fixing area 233 is provided with a first opening 271. The first opening 271 corresponds to the first support hole 2341 in the Z-axis direction, that is, an orthographic projection of the first opening 271 on the support structure 23 covers the first support hole 2341, that is, the first opening 271 exposes the first support hole 2341 in the Z-axis direction. Next, the light-transmitting structure 25 is fixed in the second groove 241 by the adhesive structure 27. Thus, after the rear housing 20 is aligned and combined with the display screen 10 and the middle frame 30, the terminal device exposes the light-transmitting structure 25 and the light-uniformizing structure 24 of the housing assembly, and the light-uniformizing structure 24 located in the third fixing area 233 surrounds the light-transmitting structure 25 from a rear view.

It can be understood that the adhesive structure 27 is disposed by a dispensing process, so as to improve the adhesion effect between the auxiliary light-transmitting structure 25 and the flashlight cover 22.
