Detailed Description

In the present embodiments, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature.

In the present embodiments, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises the element.

In the embodiment of the present application, "and/or" is merely an association relationship describing an association object, and indicates that three relationships may exist, for example, a and/or B may indicate: a exists alone, A and B exist together, and B exists alone. In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.

With the development of technology, electronic devices such as mobile phones and tablet computers include a rear camera module. Along with the increasing requirements of users on shooting definition and shooting area size of the rear-mounted camera module, the rear-mounted camera module in the electronic equipment comprises a rear-mounted wide-angle camera module and/or a rear-mounted tele camera module or comprises a plurality of rear-mounted main camera modules besides the rear-mounted main camera module, so that the number of the rear-mounted camera modules is increased. For example, currently, the number of rear camera modules in a high-end mobile phone is generally greater than or equal to 3. Meanwhile, as the requirements of users on the area of an imaging sensor of the camera module and the optical anti-shake stroke are higher and higher, the occupied area of a single camera module is larger and larger. Based on the two reasons, the occupation space of the rear camera module in the electronic equipment in the prior art is increased. In this way, the set volume of other electronic devices (such as batteries) around the rear camera module is compressed, thereby causing the performance of the other electronic devices to be degraded.

On the basis, the electronic equipment comprises a rear camera module and a flash lamp module. The flash lamp module is arranged in the electronic equipment and is installed close to the rear camera module, and is used for taking pictures or videos of the rear camera under the dark light environment to play a role in supplementing light. In order to increase the shooting performance of the rear camera module in the electronic equipment on the premise of guaranteeing the performance of other electronic devices around the rear camera, the improvement thought of the electronic equipment is to embed the flash module in the back cover where the camera decoration is located, so that the rear camera module can be accommodated by utilizing the partial space originally used for accommodating the flash module in the electronic equipment, the volume of other electronic devices around the rear camera module is not required to be compressed, the occupied space of the rear camera module in the electronic equipment can be increased, and the shooting performance of the rear camera module in the electronic equipment is guaranteed.

On the other hand, on the premise that the number of the rear camera modules 30 and the area occupied by the single rear camera module 30 are certain, a part of the space in the electronic device 100, which is originally used for accommodating the flash module 40, can be used for accommodating the battery 60, so as to increase the setting volume and capacity of the battery 60 in the electronic device 100 and improve the cruising ability of the electronic device 100.

It should be noted that, the other electronic devices described in the embodiments of the present application are not limited to the battery 60, but may be other electronic devices such as a motherboard. The following examples are illustrative of the other electronic device being the battery 60 and are not to be construed as limiting the application in any way.

In some embodiments, referring to fig. 3, the battery 60 is disposed inside the back cover main body 211, and the front projection area of the battery 60 on the back cover main body 211 overlaps with the occupied area of the accommodating hole 212b on the back cover main body 211, that is, the whole or part of the occupied area of the accommodating hole 212b on the back cover main body 211 is located in the front projection area of the battery 60 on the back cover main body 211, and the battery 60 and the accommodating hole 212b are stacked in the thickness direction (that is, the Z-axis direction) of the electronic device. In this way, under the premise that the size of the battery 60 is fixed, the rear camera module 30 is accommodated by using the part of the space in the electronic device 100 which is originally used for accommodating the flash module 40, so that the occupied space of the rear camera module in the electronic device can be increased without compressing the volume and capacity of the battery 60, and the shooting performance of the rear camera module 30 in the electronic device 100 is ensured. On the other hand, when the number of the rear camera modules 30 and the area occupied by the single rear camera module 30 are fixed, the battery 60 is accommodated in the electronic device 100 by using the part of the space originally used for accommodating the flash module 40, so that the setting volume and capacity of the battery 60 in the electronic device 100 are increased, and the cruising ability of the electronic device 100 is improved.

Since the flash module 40 has a certain height, the receiving hole 212b needs to have a certain length in order to be able to insert most or all of the flash module 40 into the back cover 21 where the camera trim 212 is located, and in order to provide the receiving hole 212b having a certain length with setting conditions, two embodiments may be adopted, which are the following first and second embodiments, respectively.

Embodiment one: an axial one section of the accommodation hole 212b is provided by the camera trim 212, and an axial other section of the accommodation hole 212b is provided by the back cover main body 211.

For example, referring to fig. 2 and 3, the orthographic projection of the camera hole 212a in the plane of the mounting opening 70 is located in the mounting opening 70, and the orthographic projection of the receiving hole 212b in the plane of the mounting opening 70 is located outside the mounting opening 70.

The camera trim 212 has a first portion A1, and the back cover main body 211 has a second portion A2, and the second portion A2 is located inside the first portion A1 and is stacked with the first portion A1. The inner side of the first portion A1 refers to a side of the first portion A1 near the internal accommodating space of the electronic device.

The receiving hole 212b includes a first through hole 212b1 and a second through hole 212b2. The first through hole 212b1 is disposed in the first portion A1, and the first through hole 212b1 penetrates through a surface of the first portion A1 near the second portion A2 and a surface of the first portion A1 far from the second portion A2. The second through hole 212b2 is disposed in the second portion A2, and the second through hole 212b2 penetrates through an inner surface of the second portion A2 and an outer surface of the second portion A2. The inner surface of the second portion A2 refers to a surface of the second portion A2 close to the internal accommodating space of the electronic device, and the outer surface of the second portion A2 refers to a surface of the second portion A2 away from the internal accommodating space of the electronic device. The second through hole 212b2 communicates with the first through hole 212b 1.

In this way, the first through hole 212b1 of the accommodating hole 212b is provided by the camera trim 212, the first through hole 212b1 forms a section of the accommodating hole 212b in the axial direction, the second through hole 212b2 of the accommodating hole 212b is provided by the back cover main body 211, and the second through hole 212b2 forms another section of the accommodating hole 212b in the axial direction, so that when the thickness of the back cover main body 211 and the thickness of the portion of the camera trim 212 located outside the back cover main body 211 are fixed, the thicknesses are larger, and the accommodating hole 212b can be ensured to have a sufficient length to be embedded with the flash module 40, so that the flash module 40 is prevented from extending outside the accommodating hole 212 b. On this basis, the size of the mounting opening 70 arranged on the back cover main body 211 is smaller, so that the structural strength of the back cover main body 211 can be ensured to a certain extent, meanwhile, the flatness of the inner surface of the back cover main body 211 is better, and the battery 60 cannot be scratched in the assembly process.

On the basis of the above embodiment, on the back cover main body 211, the distance d (refer to fig. 2) between the mounting opening 70 and the second through hole 212b2 is greater than or equal to 4mm. Specifically, the distance d may be 4mm, 5mm, 6mm, 7mm, or the like, and is not particularly limited herein. In this way, the width of the portion of the back cover main body 211 located between the mounting opening 70 and the second through hole 212b2 is made larger, and the structural strength of the portion and the structural stability of the back cover main body 211 are ensured.

The camera trim 212 has various structural forms, and the fixing manner of the camera trim 212 on the back cover main body 211 includes, but is not limited to, gluing, integral molding, screwing and clamping.

Specifically, with continued reference to fig. 3-5, the ornamental piece body 2121 is stopped against the peripheral surface of the edge of the back cover body 211 where the mounting opening 70 is located, and the first portion A1 is located on the ornamental piece body 2121. The fixing piece 2122 is stopped against the inner surface of the periphery of the back cover main body 211 where the mounting port 70 is located. The anchor 2122 is fixedly coupled to the trim body 2121. In some embodiments, referring to FIG. 4, the anchor 2122 is fixedly coupled to the trim body 2121 by a screw 80. In other embodiments, the anchor 2122 and the trim body 2121 may be fixedly attached by adhesive, snap fit, or the like.

In this way, the structure of the camera ornament 212 is simple, and the connection operation of the camera ornament 212 on the back cover main body 211 is convenient, and the cost is low.

With reference to fig. 6, fig. 6 is a schematic structural view of an inner surface of the back cover main body 211 in the electronic device shown in fig. 3-5. The front projection area of the fixing piece 2122 on the back cover main body 211 is defined as a first projection area B1, the occupied area of the mounting opening 70 on the back cover main body 211 is defined as a second area B2, and the occupied area of the second through hole 212B2 on the back cover main body 211 is defined as a third area B3. The first projection area B1 has a first outer contour edge a, which is located on the same side as the second area B2 as the third area B3. On this basis, the edge of the third region B3 close to the second region B2 is continuously defined as a first edge a1, and the edge of the third region B3 far from the second region B2 is a second edge a2. The first outer contour edge a may be located between the second area B2 and the first edge a1, may be located between the first edge a1 and the second edge a2, or may be located on a side of the second edge a2 away from the second area B2, which is not particularly limited herein.

Specifically, referring to fig. 7, fig. 7 is a schematic structural diagram of an inner surface of the back cover main body 211 in the electronic device shown in fig. 3-5 when the first outer contour edge a is located between the second area B2 and the first edge a1, or the first outer contour edge a is overlapped with the first edge a1, and the fixing member 2122 does not extend to the area where the second through hole 212B2 is located. The inner surface of the back cover 21 where the accommodating hole 212B is located is formed by the inner surface of the back cover main body 211, and the inner surface of the back cover main body 211 is generally smooth and flat, and when the battery 60 is disposed on the side of the first outer contour edge a away from the second area B2, such as the battery 60 is disposed on the inner side of the area B4 in fig. 7, the flatness of the area opposite to the battery 60 on the inner surface of the back cover 21 can be ensured, and the battery 60 is prevented from being scratched during the assembly process.

When the first outer contour edge a is located between the first edge a1 of the third area B3 and the second edge a2 of the third area B3, referring to fig. 6, the area of the fixing element 2122 that is stopped on the inner surface of the back cover main body 211 is larger, and the connection stability between the camera trim 212 and the back cover main body 211 is better. Meanwhile, when the battery 60 is disposed at the side of the first outer contour edge a, which is far from the second region B2, such as the battery 60 may be disposed at the inner side of the region B4 in fig. 6, the inner surface of the back cover 21 where the receiving hole 212B is located is partially formed by the inner surface of the back cover body 211, and the other partial region is formed by the surface of the fixing piece 2122, which is far from the garnish body 2121, such that the battery 60 is disposed at the inner side of the region formed by the inner surface of the back cover body 211 in the inner surface of the back cover 21 where the receiving hole 212B is located, so that flatness of the region on the inner surface of the back cover 21 opposite to the battery 60 can be ensured, avoiding scratching the battery 60 during assembly. On the basis of the embodiment, a avoidance notch C is disposed on the fixing member 2122 opposite to the second through hole 212b2, where the avoidance notch C is used to avoid the second through hole 212b2, so as to ensure that the accommodating hole 212b penetrates through the inner surface of the back cover 21.

Referring to fig. 8, fig. 8 is a schematic view of another structure of the inner surface of the back cover main body 211 in the electronic device shown in fig. 3-5, when the first outer contour edge a is located at the side of the third area B3 away from the second area B2, the area of the fixing member 2122 that is stopped at the inner surface of the back cover main body 211 is larger, and the assembly stability between the camera trim 212 and the back cover main body 211 is better. On this basis, in order to ensure that the receiving hole 212b penetrates the inner surface of the back cover 21, the receiving hole 212b further includes a third through hole provided on the fixing member 2122 at a position opposite to the second through hole 212b2, the third through hole communicating with the second through hole 212b2 and the first through hole 212b1 to form the receiving hole 212b. On the basis of this embodiment, the inner surface of the back cover 21 where the accommodation hole 212B is located is formed by the surface of the mount 2122 away from the garnish body 2121, and the battery 60 may be stacked on the inside of the mount 2122, for example, the battery 60 may be disposed on the inside of the region B4 in fig. 8. Like this, there is certain coincidence region in the thickness direction of electronic equipment battery 60 and second through-hole 212b2, can increase the setting quantity of rear-mounted camera module and the occupation area of single rear-mounted camera module under the prerequisite of guaranteeing battery 60's volume and capacity, promotes the shooting performance of the interior rear-mounted camera module of electronic equipment.

In combination with the above three cases, in implementation, according to a specific application scenario, the assembly stability between the camera trim 212 and the back cover main body 211, the safety of the battery 60, and the shooting performance of the rear camera module may be comprehensively considered to determine which implementation is adopted, which embodiment is not limited in the embodiment of the present application.

The receiving hole 212b may be a straight hole or a stepped hole, and is not particularly limited herein, as long as the flash module 40 can be received and fixed.

In some embodiments, referring to fig. 9, fig. 9 is a schematic cross-sectional structure of the electronic device 100 shown in fig. 1-3, where the back cover 21 is located in the accommodating hole 212 b. The receiving bore 212b includes a first bore section 212ba and a second bore section 212bb. The first hole section 212ba is disposed on the inner surface of the back cover 21, the second hole section 212bb is disposed on one side of the first hole section 212ba away from the inner surface of the back cover 21, the cross-sectional area of the second hole section 212bb is smaller than that of the first hole section 212ba, and a first step surface m1 is formed between the inner side surface of the second hole section 212bb and the inner side surface of the first hole section 212 ba.

On the basis, referring to fig. 10, fig. 10 is an exploded view of the flash module 40 in the electronic device 100 shown in fig. 1-3. The flash module 40 includes a circuit board 41 and a flash 42 disposed on the circuit board 41. The flash 42 is used to introduce electrical power via the circuit board 41. The flash 42 may be mounted on the circuit board 41 using surface mount technology (surface mount technology, SMT) to reduce the thickness of the flash module 40. The circuit board 41 includes, but is not limited to, a printed circuit board (printed circuit board, PCB) and a flexible circuit board (flexible printed circuit board, FPC).

Referring to fig. 11, fig. 11 is a schematic diagram illustrating an assembly structure of the back cover 21 shown in fig. 9 and the flash module 40 shown in fig. 10. The circuit board 41 is accommodated in the first hole section 212ba, and the circuit board 41 is fixed on the first stepped surface m 1. Specifically, the circuit board 41 may be adhesively fixed to the first step surface m1 by using an adhesive layer. The flash 41 is received in the second hole section 212 bb.

Thus, the structure composed of the circuit board 41 and the flash lamp 42 can be mounted from the inner side of the back cover 21 into the accommodation hole 212b, which is convenient for mounting operation and has high efficiency.

In some embodiments, referring back to fig. 10, when the circuit board 41 is an FPC, the flash module 40 further includes a stiffener 43. The reinforcing plate 43 is laminated on the surface of the circuit board 41 away from the flash 42. In some embodiments, the stiffener 43 is adhesively secured to the surface of the circuit board 41 remote from the flash 42 using a glue line. Referring to fig. 11, the reinforcing plate 43 is accommodated in the first hole section 212ba together with the circuit board 41. The reinforcing plate 43 is used to increase the structural strength of the circuit board 41 and prevent the circuit board 41 from being deformed by wrinkling. The reinforcing plate 43 may be selected from a metal plate, and exemplified by an aluminum plate, a steel plate, an iron plate, or the like. Thus, on the one hand, the circuit board 41 can be prevented from being wrinkled and deformed, and on the other hand, the metal material has excellent heat conduction performance, and can play a role in heat dissipation of the circuit board 41. When the circuit board 41 is a PCB, the structural strength of the circuit board 41 is excellent, and the fold deformation can be prevented by the structural strength of the circuit board itself, so that the reinforcing plate 43 may not be provided.

In some embodiments, referring to fig. 10, an end of the flash module 40 near the inner side of the back cover 21 is located in the receiving hole 212 b. Specifically, an end of the flash module 40 near the inner side of the back cover 21 is located in the first hole section 212ba of the accommodation hole 212 b. The distance h between the end face of the one end of the flash module 40 near the inner side of the back cover 21 and the inner surface of the back cover 21 where the accommodation hole 212b is located is greater than or equal to 0mm. In this way, the flash module 40 is prevented from protruding from the inner surface of the back cover 21, thereby preventing the flash module 40 from rubbing or even puncturing the battery 60 located inside the back cover 21. On this basis, in some embodiments, a distance h between an end face of the flash module 40 near the inner side of the back cover 21 and the inner surface of the back cover 21 where the accommodation hole 212b is located is greater than or equal to 0.15mm. In this way, it is ensured that the flashlight module 40 does not scratch or puncture the battery 60 inside the back cover 21.

In the above embodiment, it should be noted that, when the inner surface of the back cover 21 where the accommodating hole 212b is located is formed by the inner surface of the back cover main body 211 (see fig. 7), the distance between the end surface of the flash module 40 near the inner side of the back cover 21 and the inner surface of the back cover 21 where the accommodating hole 212b is located means: the distance between the end face of the one end of the flash module 40 near the inner side of the back cover 21 and the inner surface of the back cover main body 211. When a partial region of the inner surface of the back cover 21 where the accommodation hole 212b is located is formed by the inner surface of the back cover body 211 and another partial region is formed by the surface of the fixture 2122 away from the garnish body 2121 (see fig. 6), the distance between the end face of the one end of the flash module 40 near the inner side of the back cover 21 and the inner surface of the back cover 21 where the accommodation hole 212b is located also means: the distance between the end face of the one end of the flash module 40 near the inner side of the back cover 21 and the inner surface of the back cover main body 211. When the inner surface of the back cover 21 where the accommodation hole 212b is located is formed by the surface of the fixing piece 2122 away from the garnish body 2121 (see fig. 8), the distance between the end surface of the end of the flash module 40 close to the inner side of the back cover 21 and the inner surface of the back cover 21 where the accommodation hole 212b is located means: the end face of the one end of the flash module 40 near the inner side of the back cover 21 is distant from the surface of the fixture 2122 away from the garnish body 2121.

Since the battery 60 is disposed inside the region formed by the inner surface of the back cover body 211 in the inner surface of the back cover 21 in which the accommodation hole 212b is located when the inner surface of the back cover 21 in which the accommodation hole 212b is located is formed by the inner surface of the back cover body 211 or a partial region is formed by the inner surface of the back cover body 211, in both embodiments, it is possible to prevent the holder 2122 from rubbing or puncturing the battery 60 in addition to the flash module 40, thereby enabling to secure the safety performance of the battery 60. Note that each of the following embodiments is described on the basis that the inner surface of the back cover 21 where the accommodation hole 212b is located is formed by the inner surface of the back cover main body 211 or a partial area is formed by the inner surface of the back cover main body 211, and this is not to be construed as a particular limitation to the present application.

Specifically, when the thickness of the portion of the flash module 40 for being received in the first hole section 212ba is less than or equal to the thickness of the back cover body 211, all the sections of the first hole section 212ba may be disposed on the back cover body 211. When the thickness of the portion of the flash module 40 for being received in the first hole section 212ba is greater than the thickness of the back cover main body 211, a portion of the first hole section 212ba may be disposed on the back cover main body 211 and another portion may be disposed on the camera trim 212. In this way, the first hole section 212ba is enabled to fully accommodate the corresponding portion of the flash module 40, avoiding the flash module 40 protruding from the inner surface of the back cover body 211, thereby preventing the flash module 40 from snagging and puncturing the battery 60 located inside the back cover body 211.

In the embodiment shown in fig. 11, the portion of the flash module 40 for being received in the first hole section 212ba is a whole formed of the circuit board 41 and the reinforcing plate 43, and the circuit board 41 is an FPC, and the thickness of the FPC is thin. Thus, the thickness of the circuit board 41 is small, the sum of the thickness of the circuit board 41 and the thickness of the reinforcing plate 43 is smaller than the thickness of the back cover main body 211, and all the sections of the first hole section 212ba are provided on the back cover main body 211. This simple structure, the seting up operation of first hole section 212ba is convenient.

In other embodiments, referring to fig. 12, fig. 12 is a schematic diagram illustrating an assembly structure of the back cover 21 and the flash module 40 according to still other embodiments of the present disclosure. In the present embodiment, the portion of the flash module 40 for being received in the first hole section 212ba is a circuit board 41, and the circuit board 41 is a PCB, and the thickness of the PCB is larger than that of the FPC. Thus, the thickness of the circuit board 41 is larger than that of the back cover main body 211, and one section in the axial direction of the first hole section 212ba is provided on the back cover main body 211, and the other section is provided on the camera trim 212. Thereby, the first hole section 212ba is enabled to fully accommodate the circuit board 41, preventing the flash module 40 from protruding from the inner surface of the back cover main body 211, thereby preventing the flash module 40 from rubbing against the battery 60 located inside the back cover main body 211.

On the basis of the above embodiment, the second hole section 212bb may be disposed on the camera trim 212 in all sections, or may be disposed on the camera trim 212 in some sections, and disposed on the back cover main body 211 in another section, which is not specifically limited in the embodiment of the present application.

In some embodiments, referring to fig. 10, the one end of the electrical connection structure 46 is electrically connected to the circuit board 41 in the flash module 40. The other end of the electrical connection structure 46 has a terminal 461. Referring to fig. 15 and 16, the terminal 461 is fixed on the inner surface of the back cover 21, and the orthographic projection area of the terminal 461 on the back cover main body 211 does not overlap with the orthographic projection area (area B4 in fig. 15) of the battery 60 on the back cover main body 211. Thus, the electric connection structure 46 does not interfere with the battery 60, and the thickness of the electronic device 100 can be reduced. On this basis, the terminals 461 can be further electrically connected with the main board 50 in fig. 2 by means of abutting of elastic sheets, plugging of plugging components, and the like. In other embodiments, the terminal 461 may be further electrically connected to the auxiliary board or other control board of the electronic device by means of abutting the elastic piece, plugging the plugging component, or the like, which is not specifically limited in the embodiments of the present application.

In some embodiments, referring to fig. 14, the inner surface of the back cover 21 is provided with a fixing portion 220, the fixing portion is a boss disposed on the inner surface of the back cover 21, in other embodiments, the fixing portion 220 may be a groove disposed on the inner surface of the back cover 21, or a partial area on the inner surface of the back cover 21 that is flush with other areas, the fixing portion 220 has a fixing surface 220a, the fixing surface 220a is used for fixing the terminal 461 in fig. 10, and the fixing portion 220 is used for adjusting the height of the terminal 461 so that the terminal 461 is firmly electrically connected with the main board 50 by abutting with a spring plate, plugging in a plugging assembly, or the like.

Referring to fig. 16, the terminal 461 is fixed on the fixing surface 220a of the fixing portion 220, and the plurality of limiting protrusions 221 stop at edges of the terminal 461 to limit the terminal 461, so as to prevent the terminal 461 from being dislocated, and ensure the positioning accuracy of the terminal 461 and the alignment accuracy of the main board 50.

In the prior art, the back cover 21 needs to have a certain waterproof property, that is, the back cover 21 can prevent moisture located at the outer side of the back cover 21 from entering the inner side of the back cover 21 through the back cover 21. Since there is an assembly gap in the portion of the back cover 21 where the accommodation hole 212b is located, moisture easily permeates into the inside of the back cover 21 from this portion. There are two water seepage paths of the portion where the accommodation hole 212b is located. Referring to fig. 17, fig. 17 is a schematic diagram of two water seepage paths in the back cover 21 shown in fig. 9, the first water seepage path L1 enters the accommodating hole 212b from the gap between the light-transmitting cover plate 213 and the camera decoration 212, and enters the inner side of the back cover 21 from the accommodating hole 212b, and the sealing of the portion can be achieved by arranging a whole layer of sealant between the light-transmitting cover plate 213 and the camera decoration 212 to ensure the sealing performance. The second water penetration path L2 is formed by a gap between the trim body 2121 of the camera trim 212 and the back cover body 211, and enters the accommodation hole 212b, and enters the inside of the back cover 21 through the accommodation hole 212 b. In order to ensure the appearance refinement of the back cover 21, the gap between the main body 2121 of the decoration piece and the main body 211 of the back cover is small, and a structure with superior sealing performance such as sealing foam and sealing rubber cannot be installed, and the simple sealing is generally performed by using the back adhesive 214, so that the sealing performance of the second water seepage path L2 is poor, and the sealing performance of the second water seepage path L2 is mainly improved.

In the first sealing manner, referring to fig. 18, fig. 18 is a schematic view showing an outer surface structure of the back cover 21 shown in fig. 5 (a) after removing the main body 2121 and the transparent cover 213. A third sealing material C3 is provided between the garnish body 2121, the mount 2122, and the back cover body 211, the third sealing material C3 being disposed around the circumference of the hole group consisting of the accommodation hole 212b and one camera hole 212a, thereby preventing moisture outside the third sealing material C3 from entering the accommodation hole 212b and one camera hole 212a in the third sealing material C3. The material of the third sealing material C3 may be a sealing material having high elasticity such as a sealing foam or a sealing rubber. The third sealing material C3 has at least one screw 80 therein, and in the embodiment shown in fig. 18, the number of screws 80 is two, the two screws 80 fix the fixing member 2122 with the garnish body 2121, and the third sealing material C3 can be effectively compressed by the locking force of the two screws 80, thereby performing a sealing function to prevent moisture outside the third sealing material C3 from entering the accommodating hole 212b and the one camera hole 212a in the third sealing material C3. In this sealing manner, the camera hole 212a and the receiving hole 212b do not need to be sealed separately, so that the sealing structure is simple and the cost is low, but moisture outside the third sealing material C3 can pass through the third sealing material C3 by the gap f between the fixing member 2122 and the back cover main body 211 and enter the inner side of the third sealing material C3, so that the waterproof effect is poor.

In the second sealing manner, referring to fig. 19 and 20, fig. 19 is a schematic view showing the structure of the outside surface of the back cover 21 shown in fig. 5 (a) after removing the main body 2121 and the transparent cover plate 213, and fig. 20 is a schematic view showing the cross-sectional structure of the back cover 21 shown in fig. 19 at line B-B. A first sealing material C1 is provided between a first portion (not shown in the drawings) on the garnish body 2121 and a second portion A2 of the back cover body 211, the first sealing material C1 being provided around a circumference of the accommodation hole 212 b. On this basis, the first sealing material C1 is a sealing material having high elasticity such as a sealing foam or a sealing rubber. The sealing materials with high elasticity have better sealing performance, and can effectively prevent water vapor outside the first sealing material C1 from entering the first sealing material C1. However, the elastic sealing material has a large rebound force, which easily causes the sealant 214 between the end of the fitting body 2121 located away from the mounting port 70 of the accommodation hole 212b and the back cover body 211 to fail, and causes the end (i.e., K portion) of the fitting body 2121 located away from the mounting port 70 of the accommodation hole 212b to tilt, thereby affecting the appearance refinement of the fitting body 2121.

In the third sealing manner, the first sealing material C1 in fig. 19 and 20 is replaced by a sealing material having elasticity such as sealing foam, sealing rubber, etc. by a sealing material having small or no elastic compression such as waterproof foam, etc., and such a sealing material can perform a sealing function. On this basis, in order to limit the position of the sealing material, in some embodiments, referring to fig. 20, a sealant groove 212C is provided on the decoration main body 2121, the sealant groove 212C is disposed around a circumference of the receiving hole 212b, and the first sealing material C1 is disposed in the sealant groove 212C, thereby limiting the position of the first sealing material C1 by means of the sealant groove 212C, which is simple in structure and easy to implement. In other embodiments, the sealant groove 212c may also be provided on the back cover body 211, or on both the trim body 2121 and the back cover body 211. However, when the height of the first sealing material C1 provided between the trim main body 2121 and the back cover main body 211 is small, an effective sealing effect cannot be performed, and when the height of the first sealing material C1 is large, a gap between the trim main body 2121 and the back cover main body 211 may be caused to be large, or an end portion of the trim main body 2121 located at an end of the receiving hole 212b remote from the mounting opening 70 may be lifted up, thereby affecting the appearance refinement of the trim main body 2121.

In a fourth sealing manner, referring to fig. 21, fig. 21 is a schematic cross-sectional view of the back cover 21 shown in fig. 5 (a) after removing the main body 2121 and the transparent cover 213. In this embodiment, on the basis of the third sealing manner, the cross-sectional area of the second through hole 212b2 is larger than that of the first through hole 212b1, and the surface of the first portion A1 facing the second portion A2 is provided with a rib 212d around the first through hole 212b 1. The rib 212d is accommodated in the second through hole 212b2, and a second sealing material C2 is disposed between the rib 212d and the inner wall of the second through hole 212b 2. The second sealing material C2 may be dispensing, rubber, foam, silica gel, or the like, and is not particularly limited in the embodiment of the present application. In this way, the first sealing material C1 having a small height can be provided between the garnish body 2121 and the back cover body 21 to ensure the appearance of the camera garnish 212 to be fine, and on this basis, secondary sealing can be achieved by the second sealing material C2, thereby improving sealing performance and preventing moisture from entering.

The anchor 2122 is fixedly coupled to the trim body 2121. Specifically, the fixing element 2122 and the ornamental body 2121 may be fixedly coupled by means of adhesive, snap-fit, screw-coupling, or the like. In this way, the structure of the camera ornament 212 is simple, and the connection operation of the camera ornament 212 on the back cover main body 211 is convenient, and the cost is low.

On the basis of the above-described embodiment, one section in the axial direction of the accommodation hole 212b is provided by the garnish body 2121, and the other section in the axial direction of the accommodation hole 212b is provided by the mount 2122.
