Description

Technical Field

[0001] The present application relates to the field of camera technology, and in particular to a camera device and electronic equipment. Background Art

[0002] In order to send and receive sound signals, a camera device is typically provided with a microphone, which is fixed in a groove provided on the housing. A through-hole is provided on the inner surface of the groove, one end of which leads to the front of the microphone and the other end leads to the outside of the camera device, thereby facilitating the microphone to receive sound signals from the outside or send sound signals to the outside through the through-hole. In order to prevent external moisture or dust from entering the interior of the camera device through the through-hole and between the microphone and the inner surface of the groove, in related art, a dispensing structure is typically provided on the back of the microphone. The dispensing structure can form a sealing structure, thereby preventing moisture or dust from entering the interior of the camera device through the gap between the microphone and the inner surface of the groove.

[0003] However, the dispensing process is relatively complicated and requires a long time to cure, which can easily cause breakpoints in the assembly line, resulting in reduced production efficiency and increased manufacturing costs. Utility Model Content

[0004] In order to solve the above technical problems, the present application provides a camera device and an electronic device, which can improve the production efficiency of the camera device and reduce the manufacturing cost of the camera device.

[0005] In a first aspect of the present application, a camera device is provided, comprising: a housing, a microphone, a sealing portion and a limiting structure. A groove is provided on the housing. At least part of the microphone is located in the groove. For example, part of the microphone is located in the groove, and the rest of the microphone extends out of the groove; or, the entire structure of the microphone is located in the groove. The sealing portion is located between the microphone and the inner surface of the groove. The limiting structure is fixed to the housing, and the limiting structure also abuts against the surface of the microphone facing away from the bottom surface of the groove. The limiting structure is configured to provide pressure to the sealing portion through the microphone, so that the sealing portion abuts against the inner surface of the groove and the outer surface of the microphone under the action of pressure.

[0006] The housing is typically provided with a first through-hole, which is located on the bottom surface of the groove. The sealing portion is typically provided with a second through-hole, which is connected to the first through-hole. The microphone has a front and a back surface, wherein the front surface may refer to the surface that receives and transmits sound signals, and the back surface is the surface opposite to the front surface. The front surface of the microphone may face the bottom surface of the groove and abut against the interior of the sealing portion. In this way, the microphone can receive sound signals from the outside and transmit signals to the outside through the second through-hole in the sealing portion and the first through-hole in the housing.

[0007] During the use of the camera device, external water vapor or dust often enters the interior of the camera device through the first through hole and the second through hole, as well as the gap between the sealing part and the microphone, thereby causing damage to components such as the lens. However, in the present application, the sealing part abuts against the inner surface of the groove under the action of pressure, thereby preventing a gap from forming between the sealing part and the inner surface of the groove. The sealing part also abuts against the outer surface of the microphone under the action of pressure, thereby preventing a gap from forming between the sealing part and the outer surface of the microphone. In this way, it is possible to achieve sealing between the sealing part and the inner surface of the groove, as well as sealing between the sealing part and the microphone, thereby preventing water vapor and dust from entering the interior of the camera device from between the sealing part and the inner surface of the groove, as well as between the sealing part and the microphone.

[0008] Since in the present application, the sealing of the camera device is achieved by a limiting structure and a sealing part, when manufacturing the camera device, the manufactured limiting structure can be fixed on the shell and the next process can be continued, eliminating the curing waiting time of the glue dispensing structure, thereby not causing breakages in the assembly line, and thus improving the production efficiency of the camera device and reducing the manufacturing cost of the camera device.

[0009] In addition, the limiting structure can usually be made of materials such as metal or plastic, which have stable material properties and are not easy to age, thereby being able to maintain good sealing for a long time.

[0010] Regarding the structure of the sealing portion, in one possible embodiment, the sealing portion includes an elastic seal and a rib structure. The elastic seal is positioned within the groove, and the rib structure is positioned between the elastic seal and the inner surface of the groove. The projected area of ​​the rib structure on the elastic seal is smaller than the outer surface area of ​​the elastic seal. If the elastic seal deforms under pressure, the elastic seal and the inner surface of the groove are in closer contact. Therefore, the transverse dimension of the sealing portion needs to be larger than the transverse dimension of the groove. If the sealing portion does not include the rib structure, the dimensions of the elastic seal need to be larger than the dimension of the groove along the first direction, making it difficult to install the elastic seal into the groove. If the sealing portion includes both the elastic seal and the rib structure, because the dimension of the rib structure along the first direction is smaller than the dimension of the elastic seal along the first direction, the contact area between the rib structure and the sidewalls of the groove is smaller. During installation, the sidewalls of the groove provide less resistance to the sealing portion, making it easier to install the sealing portion into the groove. In other words, the sealing portion is easier to install.

[0011] In some embodiments of the present application, at least a portion of the elastic seal is located between the microphone and the side wall of the groove. For example, a portion of the elastic seal is located between the microphone and the side wall of the groove, or the entire elastic seal is located between the microphone and the side wall of the groove. The rib structure includes a first rib, the first rib is an annular structure, the first rib is sleeved on the outer surface of the elastic seal, and abuts against the side wall of the groove. Along the first direction, the size of the first rib is smaller than the size of the elastic seal, and the first direction is the direction in which the microphone points to the limiting structure. In this way, the first rib in an annular structure can form a circle of sealing structure between the elastic seal and the side wall of the groove, thereby preventing water vapor or dust from entering the interior of the camera device from between the elastic seal and the side wall of the groove.

[0012] Specifically, the rib structure includes at least two first ribs spaced apart from each other. The greater the number of first ribs, the better the sealing performance between the elastic seal and the sidewall of the groove. Therefore, when the rib structure includes at least two first ribs, the sealing performance between the elastic seal and the sidewall of the groove can be improved.

[0013] In one example, the first rib is provided on the elastic seal and forms an integral structure with the elastic seal. The elastic seal can generally be made of an elastic material such as rubber. In this solution, the material of the first rib can be the same as that of the elastic seal, that is, an elastic material such as rubber can also be used. In this way, on the one hand, when the limiting structure provides pressure to the sealing part through the microphone, both the elastic seal and the first rib can be deformed. On the other hand, when the first rib and the elastic seal form an integral structure, injection molding can be used to manufacture the elastic seal and the first rib at the same time, thereby making the sealing part simpler to manufacture. Compared with the solution in which the first rib and the elastic seal adopt a split structure, the positioning process of the first rib is omitted, and therefore the assembly process is also simpler and more convenient.

[0014] In another embodiment, the first rib is provided on the sidewall of the recess and forms an integral structure with the housing. The housing is typically made of a rigid material such as metal or plastic. Therefore, in this embodiment, the first rib is made of the same material as the housing, i.e., metal or plastic. When the elastic seal is deformed by the retaining structure, the protruding first rib acts on the outer surface of the elastic seal, forming a recessed portion therein. Part of the first rib is embedded in the recessed portion, thereby achieving a seal between the elastic seal and the first rib. Because the first rib and the housing are integrally formed, the seal between the first rib and the housing is also improved. Furthermore, when the first rib and the housing are integrally formed, the elastic seal and the first rib can be manufactured simultaneously through injection molding, simplifying the production of the seal. Compared to designs where the first rib and the elastic seal are separate components, the positioning step of the first rib is eliminated, making the assembly process simpler and more convenient.

[0015] In some embodiments of the present application, at least a portion of the elastic seal is located between the microphone and the bottom surface of the groove. For example, a portion of the elastic seal is located between the microphone and the bottom surface of the groove, or the entire elastic seal is located between the microphone and the bottom surface of the groove. The rib structure includes a second rib, the second rib is located between the elastic seal and the bottom surface of the groove, the second rib is in the form of an elongated strip, and both ends of the second rib are in contact with the side walls of the groove. Along the second direction, the size of the second rib is smaller than the size of the elastic seal, and the second direction is perpendicular to the first direction. In this way, the second rib can form a sealing structure between the elastic seal and the groove that extends from one side wall of the groove to the other side wall, thereby preventing water vapor or dust from entering the interior of the camera device from between the elastic seal and the bottom surface of the groove.

[0016] Specifically, the rib structure includes at least two second ribs spaced apart from each other. The greater the number of second ribs, the better the sealing performance between the elastic seal and the bottom surface of the groove. Therefore, when the rib structure includes at least two second ribs, the sealing performance between the elastic seal and the bottom surface of the groove can be improved.

[0017] In one example, the second rib is provided on the elastic seal and forms an integral structure with the elastic seal. The elastic seal can generally be made of an elastic material such as rubber. In this solution, the material of the second rib can be the same as that of the elastic seal, that is, an elastic material such as rubber can also be used. In this way, on the one hand, when the limiting structure provides pressure to the sealing part through the microphone, both the elastic seal and the second rib can be deformed. On the other hand, when the second rib and the elastic seal form an integral structure, injection molding can be used to manufacture the elastic seal and the second rib at the same time, thereby making the sealing part simpler to manufacture. Compared with the solution in which the second rib and the elastic seal adopt a split structure, the positioning process of the second rib is omitted, and therefore the assembly process is also simpler and more convenient.

[0018] In another embodiment, the second rib is provided on the sidewall of the groove and forms an integral structure with the housing. The housing is typically made of a rigid material such as metal or plastic. Therefore, in this embodiment, the second rib is made of the same material as the housing, i.e., it can also be made of metal or plastic. On the one hand, when the elastic seal is deformed by the retaining structure, the protruding second rib acts on the outer surface of the elastic seal, forming a recessed portion therein. Part of the second rib is embedded in the recessed portion, thereby achieving a seal between the elastic seal and the first rib. Because the second rib and the housing are integrally formed, the seal between the second rib and the housing is also improved. Furthermore, when the second rib and the housing are integrally formed, the elastic seal and the second rib can be manufactured simultaneously using injection molding, which simplifies the production of the seal. Compared to an embodiment in which the second rib and the elastic seal are separate components, the positioning step of the second rib is eliminated, making the assembly process simpler and more convenient.

[0019] Regarding the structure of the sealing portion, in another possible embodiment, the sealing portion includes an elastic seal instead of a rib structure. Therefore, the solution is relatively simple. In this case, part of the elastic seal is located between the microphone and the sidewalls of the groove, and part of the elastic seal is located between the microphone and the bottom surface of the groove. When the limiting structure applies pressure to the elastic seal through the microphone, the elastic seal deforms under the action of this pressure, causing the side surfaces of the elastic seal to abut the sidewalls of the groove, and the bottom surface of the elastic seal to abut the bottom surface of the groove, thereby achieving a seal between the sealing portion and the inner surface of the groove. The side surfaces of the elastic seal located within the groove contact the sidewalls of the groove, resulting in a larger contact area between the elastic seal and the sidewalls of the groove. The entire bottom surface of the elastic seal contacts the bottom surface of the groove, resulting in a larger contact area between the elastic seal and the bottom surface of the groove. The larger the contact area, the better the sealing performance. Therefore, this solution can achieve better sealing with a relatively simple structure.

[0020] In some embodiments of the present application, the sidewall of the groove includes a first sidewall segment close to the bottom surface and a second sidewall segment connected to the end of the first sidewall segment facing away from the bottom surface, and the dimension of at least a portion of the second sidewall segment along the second direction gradually increases from the end connected to the first sidewall segment toward the end facing away from the first sidewall segment. In other words, at least a portion of the second sidewall segment is an inclined sidewall, for example, the entire second sidewall segment is an inclined sidewall. Alternatively, the first portion of the second sidewall segment is an inclined sidewall, the second portion of the second sidewall segment has the same dimension along the second direction, and the second portion is located at the end of the first portion facing away from the first sidewall segment. Therefore, the dimension of the second portion along the second direction is greater than the dimension of the first sidewall segment along the second direction. Since the dimension of the sealing portion along the second direction is greater than the dimension of the sidewall of the groove along the second direction, when assembling the camera device, it is convenient to install the sealing portion from the second portion with a larger dimension in the second direction and the first portion with an inclined sidewall into the first sidewall segment.

[0021] In some embodiments of the present application, the camera device further includes a rear housing, the rear housing being fixed to the housing, the rear housing including a main body and a retaining structure extending from the main body. Camera devices in related art are typically provided with a rear housing. If the retaining structure is a structure extending from the main body of the rear housing, then the rear housing of related art can be appropriately improved. Moreover, in related art, the rear housing itself is fixed to the housing by screwing, welding, or gluing, so there is no need to design an additional connection structure for the retaining structure to be fixed to the housing.

[0022] In other embodiments of the present application, the camera device further includes a rear housing, and a gap is formed between the rear housing and the retaining structure. In other words, the retaining structure and the rear housing are two independent structures. In other words, the present application can be implemented by adding the retaining structure based on the relevant technology without modifying the rear housing, thereby not affecting the mold for manufacturing the rear housing and, therefore, avoiding the cost increase caused by remaking the mold for the rear housing.

[0023] In a second aspect of the present application, an electronic device is provided, comprising a controller and the camera device of any one of the above embodiments, wherein the controller is electrically connected to the camera device. The electronic device can achieve all the effects of the camera device. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0042] In the description of the embodiments of this application, unless otherwise specified, "multiple" means two or more. For example, "multiple processing units" means two or more processing units; "multiple systems" means two or more systems.

[0043] In order to send and receive sound signals, such as Figure 1 As shown, the camera device 1 is generally provided with a microphone 20, which is fixed in a groove 11 provided on the housing 10. A first through hole 1114 is provided on the inner surface 111 of the groove 11 of the housing 10. One end of the first through hole 1114 leads to the front surface 21 of the microphone 20, and the other end leads to the outside of the camera device 1, thereby facilitating the microphone 20 to receive sound signals from the outside or send sound signals to the outside through the first through hole 1114. In order to prevent external moisture or dust from entering the interior of the camera device 1 through the first through hole 1114 and between the microphone 20 and the inner surface 111 of the groove 11, in the related art, a dispensing structure 60 is generally provided on the back surface 22 of the microphone 20. The dispensing structure 60 can form a sealing structure, thereby preventing moisture or dust from entering the interior of the camera device 1 through the space between the microphone 20 and the inner surface 111 of the groove 11.

[0044] However, the dispensing process is relatively complicated and requires a long time to cure, which can easily cause breakpoints in the assembly line, resulting in reduced production efficiency and increased manufacturing costs.

[0045] Based on this, an embodiment of the present application provides a camera device 1. The camera device 1 can be a camera device 1 that is installed and used independently, such as a dome camera. The camera device 1 can also be a camera device 1 integrated into an electronic device. In this scenario, the electronic device can further include a controller that is electrically connected to the camera device 1. The controller can be used to control the camera device 1 to perform operations such as capturing images and uploading image information.

[0046] Here, electronic devices may be, for example, consumer electronic products, home electronic products, vehicle-mounted electronic products, financial terminal products, communication electronic products, etc., and the embodiments of the present application do not limit this. For example, the above-mentioned consumer electronic products may be mobile phones, tablet computers, laptop computers, personal computers (PCs), personal digital assistants (PDAs), smart wearable products (e.g., smart watches, smart bracelets, etc.), virtual reality (VR) terminal devices, augmented reality (AR) terminal devices, drones, etc. Home electronic products may be smart door locks, televisions, smart speakers, refrigerators, sweeping robots, etc. Vehicle-mounted electronic products may be vehicle-mounted navigation systems, vehicle-mounted displays, etc. Financial terminal products may be automated teller machines (ATMs), electronic devices for self-service transactions, etc.

[0047] For the convenience of description, three directions are defined here, namely Figure 2 The Z direction (first direction) shown in FIG. Figure 2 The X direction (second direction) shown and Figure 4 The Y direction (third direction) shown, the X direction, the Y direction and the Z direction are perpendicular to each other.

[0048] like Figure 2 As shown, the camera device 1 may include: a housing 10, a microphone 20, a sealing portion 30, and a limiting structure 40. The housing 10 may be a housing 10 that secures components such as a lens, microphone 20, and a fill light on the camera device 1. The housing 10 is provided with a recess 11. The inner surface 111 of the recess 11 may include a bottom surface 1113 and sidewalls 1112. The housing 10 is also provided with a first through hole 1114, which is located on the bottom surface 1113 of the recess 11.

[0049] At least part of the microphone 20 is located in the groove 11. For example, part of the microphone 20 is located in the groove 11, and the rest of the microphone 20 extends out of the groove 11. Or, Figure 2 As shown, the entire structure of the microphone 20 is located within the recess 11. The microphone 20 has a front surface 21 and a back surface 22. The front surface 21 may refer to the surface that receives and transmits sound signals, while the back surface 22 is the surface facing away from the front surface 21. In this embodiment, the front surface 21 faces the bottom surface 1113 of the recess 11, and the back surface 22 faces away from the bottom surface 1113 of the recess 11.

[0050] like Figure 2As shown, the sealing portion 30 is located between the microphone 20 and the inner surface 111 of the groove 11. The sealing portion 30 is provided with a second through hole 33, which is communicated with the first through hole 1114.

[0051] like Figure 2 As shown, the retaining structure 40 is fixed to the housing 10 and abuts against the surface of the microphone 20 that faces away from the bottom surface 1113 of the groove 11. The retaining structure 40 is configured to apply pressure to the sealing portion 30 through the microphone 20, so that the sealing portion 30 abuts against the inner surface 111 of the groove 11 and the outer surface of the microphone 20 under the action of pressure. In other words, the retaining structure 40 can provide axial (Z-direction) positioning for the microphone 20.

[0052] like Figure 2 As shown, the front face 21 of the microphone 20 abuts against the interior of the sealing portion 30 , so that the microphone 20 can receive sound signals from the outside and transmit signals to the outside through the second through hole 33 on the sealing portion 30 and the first through hole 1114 on the housing 10 .

[0053] During use of the camera device 1, external moisture or dust can often enter the camera device 1 through the first through-hole 1114 and the second through-hole 33, as well as the gap between the sealing portion 30 and the microphone 20, causing damage to components such as the lens. However, in this embodiment, the sealing portion 30 abuts against the inner surface 111 of the groove 11 under pressure, thereby preventing the formation of a gap between the sealing portion 30 and the inner surface 111 of the groove 11. The sealing portion 30 also abuts against the outer surface of the microphone 20 under pressure, thereby preventing the formation of a gap between the sealing portion 30 and the outer surface of the microphone 20. This ensures a tight seal between the sealing portion 30 and the inner surface 111 of the groove 11, as well as between the sealing portion 30 and the microphone 20, preventing moisture and dust from entering the camera device 1 through the gaps between the sealing portion 30 and the inner surface 111 of the groove 11, and between the sealing portion 30 and the microphone 20.

[0054] Since the sealing of the camera device 1 is achieved by the limiting structure 40 and the sealing portion 30 in this embodiment, when manufacturing the camera device 1, the manufactured limiting structure 40 can be fixed on the housing 10 and the next step can be continued, eliminating the need for the sealing portion 30. Figure 1 The curing waiting time of the dispensing structure 60 shown will not cause a break in the assembly line, thereby improving the production efficiency of the camera device 1 and reducing the manufacturing cost of the camera device 1.

[0055] In addition, Figure 1In the related art shown, there may be compatibility issues between the glue structure 60 and the groove 11 of the housing 10. In addition, the glue structure 60 is prone to aging, which may lead to sealing failure. In this embodiment, the limiting structure 40 can generally be made of materials such as metal or plastic, which have stable material properties and are not easily aged, thereby maintaining good sealing for a long time.

[0056] like Figure 2 As shown, the sealing portion 30 includes an elastic seal 31 and a rib structure 32. The elastic seal 31 is located within the groove 11, and the rib structure 32 is located between the elastic seal 31 and the inner surface 111 of the groove 11. The projected area of ​​the rib structure 32 on the elastic seal 31 is smaller than the outer surface area of ​​the elastic seal 31. If the elastic seal 31 deforms under pressure, the contact between the elastic seal 31 and the inner surface 111 of the groove 11 will be closer. For this reason, the dimension of the sealing portion 30 along the X-direction needs to be larger than the dimension of the groove 11 along the X-direction. If the sealing portion 30 does not include the rib structure 32, the dimension of the elastic seal 31 along the X-direction needs to be larger than the dimension of the groove 11 along the X-direction, which will make it difficult for the elastic seal 31 to fit into the groove 11. When the sealing portion 30 includes the elastic sealing member 31 and the rib structure 32, because the projected area of ​​the rib structure 32 on the elastic sealing member 31 is smaller than the outer surface area of ​​the elastic sealing member 31, the contact area between the rib structure 32 and the sidewall 1112 of the groove 11 is smaller. Therefore, when the sealing portion 30 is installed into the groove 11, the sidewall 1112 of the groove 11 provides less resistance to the sealing portion 30, making it easier to install the sealing portion 30 into the groove 11. In other words, the sealing portion 30 is easier to install.

[0057] like Figure 2 As shown, part of the elastic seal 31 is located between the microphone 20 and the side wall 1112 of the groove 11 , and part of the elastic seal 31 is located between the microphone 20 and the bottom surface 1113 of the groove 11 .

[0058] like Figure 3 As shown, the rib structure 32 includes a first rib 321. The first rib 321 is an annular structure. The first rib 321 is sleeved on the outer surface of the elastic seal 31 and is in contact with the elastic seal 31. Figure 2 The side wall 1112 of the groove 11 shown in FIG. 1 is abutted. Along the Z direction, the size of the rib structure 32 is smaller than the size of the elastic seal 31. Figure 2 As shown, the first rib 321 with an annular structure can form a radial sealing structure between the elastic seal 31 and the side wall 1112 of the groove 11, thereby preventing water vapor or dust from entering the interior of the camera device 1 from between the elastic seal 31 and the side wall 1112 of the groove 11.

[0059] In this embodiment, if Figure 3As shown, the rib structure 32 includes at least two first ribs 321 spaced apart from each other. The greater the number of first ribs 321, the better the seal between the elastic seal 31 and the sidewall 1112 of the groove 11. Therefore, when the rib structure 32 includes at least two first ribs 321, the seal between the elastic seal 31 and the sidewall 1112 of the groove 11 can be improved. In other embodiments, the rib structure 32 may include only one first rib 321.

[0060] like Figure 2 As shown, the first rib 321 is provided on the elastic seal 31 and forms an integral structure with the elastic seal 31. The elastic seal 31 can generally be made of an elastic material such as rubber. In this embodiment, the material of the first rib 321 can be the same as that of the elastic seal 31, that is, it can also be made of an elastic material such as rubber. Thus, on the one hand, when the limiting structure 40 applies pressure to the sealing portion 30 through the microphone 20, both the elastic seal 31 and the first rib 321 can be deformed. On the other hand, when the first rib 321 and the elastic seal 31 form an integral structure, the elastic seal 31 and the first rib 321 can be manufactured simultaneously by injection molding, thereby simplifying the manufacture of the sealing portion 30. Furthermore, compared to an embodiment in which the first rib 321 and the elastic seal 31 are separated, the positioning step of the first rib 321 is eliminated, thereby simplifying the assembly process.

[0061] It can be understood that when the limiting structure 40 provides pressure to the sealing part 30 through the microphone 20, the elastic seal 31 and the first rib 321 are compressed under the action of the pressure, and the compression amount can be 20%-30% of the size of the elastic seal 31 and the first rib 321 in the unstressed state.

[0062] like Figure 2 As shown, the rib structure 32 includes a second rib 322, and the second rib 322 is located between the elastic sealing member 31 and the bottom surface 1113 of the groove 11. Figure 4 As shown, the second rib 322 is a long strip structure, and both ends of the second rib 322 are in contact with the side wall 1112 of the groove 11. Along the X direction, the size of the rib structure 32 is smaller than Figure 2 Thus, the second rib 322 can form a sealing structure between the elastic seal 31 and the groove 11, extending from one side wall 1112 of the groove 11 to the other side wall 1112 of the groove 11, thereby preventing moisture or dust from entering the interior of the camera device 1 from between the elastic seal 31 and the bottom surface 1113 of the groove 11.

[0063] In this embodiment, the rib structure 32 includes at least two second ribs 322 spaced apart from each other. The greater the number of second ribs 322, the better the seal between the elastic seal 31 and the bottom surface 1113 of the groove 11. Therefore, when the rib structure 32 includes at least two second ribs 322, the seal between the elastic seal 31 and the bottom surface 1113 of the groove 11 is improved. In other embodiments, the rib structure 32 may include only one second rib 322.

[0064] In this embodiment, if Figure 2 As shown, the second rib 322 is provided on the sidewall 1112 of the groove 11 and forms an integral structure with the housing 10. The housing 10 can generally be made of a rigid material such as metal or plastic. Therefore, in this embodiment, the second rib 322 is made of the same material as the housing 10, that is, it can also be made of a material such as metal or plastic. On the one hand, when the elastic seal 31 is deformed by the limiting structure 40, the protruding second rib 322 can act on the outer surface of the elastic seal 31, thereby forming a recessed portion on the outer surface of the elastic seal 31, and a portion of the second rib 322 is embedded in the recessed portion, thereby achieving a seal between the elastic seal 31 and the first rib 321. Since the second rib 322 forms an integral structure with the housing 10, the seal between the second rib 322 and the housing 10 is also better. On the other hand, when the second rib 322 and the housing 10 are integrally formed, injection molding can be used to simultaneously manufacture the elastic seal 31 and the second rib 322, thereby simplifying the manufacture of the sealing portion 30. Furthermore, compared to a solution in which the second rib 322 and the elastic seal 31 are separate structures, the positioning step of the second rib 322 is omitted, thus simplifying and facilitating the assembly process.

[0065] In this embodiment, if Figure 2 As shown, the sidewall 1112 of the groove 11 includes a first sidewall section 1115 close to the bottom surface 1113 and a second sidewall section 1116 connected to the end of the first sidewall section 1115 facing away from the bottom surface 1113. The dimension of at least a portion of the second sidewall section 1116 along the X-direction gradually increases from the end connected to the first sidewall section 1115 toward the end facing away from the first sidewall section 1115. In other words, at least a portion of the second sidewall section 1116 is an inclined sidewall. For example, the entire second sidewall section 1116 is an inclined sidewall. Or, as Figure 2As shown, the first portion 1116a of the second sidewall segment 1116 is an inclined sidewall, while the second portion 1116b of the second sidewall segment 1116 has the same dimensions along the X-direction throughout. The second portion 1116b is located at the end of the first portion 1116a facing away from the first sidewall segment 1115. Therefore, the dimension of the second portion 1116b along the X-direction is greater than the dimension of the first sidewall segment 1115 along the X-direction. Because the dimension of the sealing portion 30 along the X-direction is greater than the dimension of the sidewall 1112 of the groove 11 along the X-direction, when assembling the camera device 1, it is easier to install the sealing portion 30 from the second portion 1116b (with the larger X-direction dimension) and the first portion 1116a (with the inclined sidewall) into the first sidewall segment 1115.

[0066] like Figure 5 As shown, the camera device 1 further includes a rear shell 50, which is fixed to the housing 10. The rear shell 50 includes a main body 51 and a limiting structure 40 extending from the main body 51. The camera device 1 in the related art is usually provided with a rear shell 50. If the limiting structure 40 is a structure extending from the main body 51 of the rear shell 50, then the rear shell 50 in the related art can be appropriately improved. Moreover, the rear shell 50 in the related art itself is fixed to the housing 10 by screwing, welding, or gluing. Therefore, there is no need to design an additional connection structure for fixing the limiting structure 40 to the housing 10.

[0067] In other embodiments of the present application, Figure 2 The difference between the embodiments shown is the structure of the sealing portion 30. Specifically, Figure 6 As shown, the sealing portion 30 includes an elastic sealing member 31 but does not include a rib structure 32. Therefore, the solution is relatively simple.

[0068] In this case, a portion of the elastic seal 31 is located between the microphone 20 and the sidewall 1112 of the groove 11, and another portion of the elastic seal 31 is located between the microphone 20 and the bottom surface 1113 of the groove 11. When the limiting structure 40 applies pressure to the elastic seal 31 through the microphone 20, the elastic seal 31 deforms under the action of this pressure, causing the side surfaces of the elastic seal 31 to abut against the sidewall 1112 of the groove 11, and the bottom surface of the elastic seal 31 to abut against the bottom surface 1113 of the groove 11, thereby achieving a seal between the sealing portion 30 and the inner surface 111 of the groove 11. Furthermore, the side surfaces of the portion of the elastic seal 31 located within the groove 11 are in contact with the sidewall 1112 of the groove 11, resulting in a larger contact area between the elastic seal 31 and the sidewall 1112 of the groove 11. The entire bottom surface of the elastic seal 31 contacts the bottom surface 1113 of the groove 11, so the contact area between the elastic seal 31 and the bottom surface 1113 of the groove 11 is also large. The larger the contact area, the better the sealing performance. Therefore, this solution can achieve better sealing performance with a relatively simple structure.

[0069] In other embodiments of the present application, Figure 2 The difference shown is that the structure of the elastic seal 31 and the embodiment are Figure 2 The second rib 322 is removed from the embodiment shown. Figure 7 As shown, the elastic seal 31 is located between the microphone 20 and the sidewall 1112 of the groove 11. In this embodiment, the elastic seal 31 is annular and is sleeved onto the outer surface of the microphone 20. The outer surface of the elastic seal 31 abuts the inner surface of the first rib 321, and the outer surface of the first rib 321 abuts the sidewall 1112 of the groove 11.

[0070] In other embodiments of the present application, Figure 2 The difference shown is that the structure of the elastic seal 31 and the embodiment are Figure 2 The first rib 321 is removed from the embodiment shown. Figure 8 As shown, the elastic seal 31 is located between the microphone 20 and the bottom surface 1113 of the groove 11. In this embodiment, the microphone 20 and the elastic seal 31 are stacked along the Z-direction, with the outer surface of the microphone 20 abutting the sidewall 1112 of the groove 11, and the outer surface of the elastic seal 31 also abutting the sidewall 1112 of the groove 11. The bottom surface of the elastic seal 31 abuts the top surface of the second rib 322, and the bottom surface of the second rib 322 abuts the bottom surface 1113 of the groove 11.

[0071] In other embodiments of the present application, Figure 2 The difference between the embodiments shown is the location of the first rib 321. Figure 9As shown, the first rib 321 is provided on the sidewall 1112 of the groove 11 and forms an integral structure with the housing 10. The housing 10 can generally be made of a rigid material such as metal or plastic. Therefore, in this embodiment, the first rib 321 is made of the same material as the housing 10, that is, it can also be made of a material such as metal or plastic. On the one hand, when the elastic seal 31 is deformed by the limiting structure 40, the protruding first rib 321 can act on the outer surface of the elastic seal 31, thereby forming a recessed portion on the outer surface of the elastic seal 31, and a portion of the first rib 321 is embedded in the recessed portion, thereby achieving a seal between the elastic seal 31 and the first rib 321. Since the first rib 321 forms an integral structure with the housing 10, the seal between the first rib 321 and the housing 10 is also good. On the other hand, when the first rib 321 and the housing 10 are integrally formed, injection molding can be used to simultaneously manufacture the elastic seal 31 and the first rib 321, thereby simplifying the manufacture of the sealing portion 30. Furthermore, compared to a solution in which the first rib 321 and the elastic seal 31 are separate structures, the positioning step of the first rib 321 is omitted, thus simplifying and facilitating the assembly process.

[0072] In other embodiments of the present application, Figure 2 The difference between the embodiments shown is the location of the second rib 322. Figure 10 As shown, the second rib 322 is provided on the elastic seal 31 and forms an integral structure with the elastic seal 31. The elastic seal 31 can generally be made of an elastic material such as rubber. In this embodiment, the material of the second rib 322 can be the same as that of the elastic seal 31, that is, it can also be made of an elastic material such as rubber. In this way, on the one hand, when the limiting structure 40 applies pressure to the sealing portion 30 through the microphone 20, both the elastic seal 31 and the second rib 322 can be deformed. On the other hand, when the second rib 322 and the elastic seal 31 form an integral structure, the elastic seal 31 and the second rib 322 can be manufactured simultaneously by injection molding, thereby simplifying the manufacture of the sealing portion 30. On the other hand, compared to an embodiment in which the second rib 322 and the elastic seal 31 are separated, the positioning process of the second rib 322 is eliminated, thereby simplifying the assembly process.

[0073] In other embodiments of the present application, Figure 5 The difference between the illustrated embodiments is the structure of the rear housing 50. Specifically, Figure 11As shown, there is a distance D between the rear cover 50 and the limiting structure 40. In other words, the limiting structure 40 and the rear cover 50 are two independent structures. In other words, this embodiment can be implemented by adding the limiting structure 40 based on the relevant technology without modifying the rear cover 50, thereby not affecting the mold for manufacturing the rear cover 50. Therefore, there is no cost increase caused by remaking the mold for the rear cover 50.

[0074] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.
