Description

Technical Field

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

[0002] With the continuous upgrade of mobile phone hardware, the camera components inside the phone are also getting larger, which in turn leads to increased power consumption and heat generation. The camera assembly consists of a camera and a housing. For the camera assembly, the use of foam sealing between the housing and the camera can achieve dust protection, but foam cannot isolate water vapor. When the phone is operating in a high-humidity environment, the humidity of the gas in the cavity between the housing, camera, and lens will increase. In this case, when using the camera to shoot or record, the increased camera temperature will create a temperature difference on the inside of the lens, causing condensation on the lens surface (called fogging), which seriously affects the user's normal use. Utility Model Content

[0003] The purpose of this application is to disclose a camera assembly and an electronic device.

[0004] In a first aspect, the present application discloses a camera assembly comprising a housing, a camera, a lens, a first vapor barrier, and a second vapor barrier. The housing, the camera, and the lens form a cavity; the first vapor barrier is hermetically connected to the housing and the camera; and the second vapor barrier is hermetically connected to the housing and the lens to seal the cavity.

[0005] In some embodiments, the first water vapor barrier is sealed and bonded to the housing, and the first water vapor barrier includes an elastic member, and the elastic member is elastically and sealedly abutted against the camera.

[0006] In some embodiments, the elastic member includes a trumpet-shaped sealing portion, the sealing portion abuts against the camera, and / or the elastic member is a silicone member.

[0007] In some embodiments, the elastic member is a silicone member, and the first water vapor insulating member further includes a supporting member, which is assembled with the elastic member and bonded to the housing.

[0008] In some embodiments, the support member is bonded to the housing by double-sided tape or glue.

[0009] In some embodiments, the support member is annular and surrounds the elastic member.

Based on the insulating effect of the first vapor barrier and the second vapor barrier, water vapor is effectively prevented from entering the cavity, thereby controlling the humidity of the cavity environment. This prevents the lens from fogging when the camera heats up, thus avoiding the problem of lens fogging when the user uses an electronic device (such as a mobile phone). In particular, this problem is avoided when the electronic device is used in a high humidity environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 is an exploded view of a camera assembly according to an embodiment of the present application;

[0016] Figure 2 yes Figure 1 a cutaway view of the camera assembly shown;

[0017] Figure 3 yes Figure 2 Enlarged view of part A. DETAILED DESCRIPTION

[0018] Here, the technical solutions in the embodiments (or "implementations") of the present application will be clearly and completely described in conjunction with the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0019] If there are terms related to directional indications or positional relationships in the embodiments of this application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationship, movement, etc. between the components in a specific posture (as shown in the accompanying drawings); if the specific posture changes, the directional indication or positional relationship will also change accordingly. In addition, the terms "first" and "second" in the embodiments of this application are only used for the purpose of convenience of description and should not be understood as indicating or implying relative importance.

[0020] See also Figure 1 、 Figure 2 and Figure 3 In a first aspect, the present application discloses a camera assembly, comprising a housing 1, a camera 2, a lens 3, a first water vapor barrier 4, and a second water vapor barrier 5. The housing 1, the camera 2, and the lens 3 constitute a cavity 10. The housing 1, the camera 2, and the lens 3 can be assembled in any structure to form the cavity 10. The first water vapor barrier 4 is sealed to the housing 1 and the camera 2; and the second water vapor barrier 5 is sealed to the housing 1 and the lens 3 to seal the cavity 10.

[0021] An assembly environment of the camera assembly of the present application is: temperature is 20°C, humidity ≤30% or 25°C, humidity ≤45%. The assembly environment determines the initial state of the cavity environment, so the required assembly environment is a critical environment in which the lens does not fog when the camera is used.

[0022] As described above, the first vapor barrier 4 is sealedly connected to the housing 1 and the camera 2; and the second vapor barrier 5 is sealedly connected to the housing 1 and the lens 3. Thus, based on the insulating effect of the first vapor barrier 4 and the second vapor barrier, water vapor is effectively prevented from entering the cavity 10, thereby controlling the humidity of the cavity 10 environment. This ensures that when the camera 2 heats up, the lens 3 does not fog, thereby avoiding the problem of the lens 3 fogging when the user uses an electronic device (such as a mobile phone). In particular, the problem of the lens 3 fogging when the electronic device is used in a high humidity environment is avoided.

[0023] Based on the functions of the first water vapor barrier 4 and the second water vapor barrier 5 , the structure of the first water vapor barrier 4 and the second water vapor barrier 5 is not limited, as long as they can at least have the function of isolating water vapor.

[0024] See also Figure 2 and Figure 3 The first water vapor barrier 4 is sealed and bonded to the housing 1. The first water vapor barrier 4 includes an elastic member 41. The elastic member 41 elastically and sealedly abuts against the camera 2. The first water vapor barrier 4 can be a component as in the present application, or a single component.

[0025] As set up as described above, the sealing effect is good and the bonding is easy to achieve by the sealed bonding of the first water vapor insulating member 4 and the shell 1, and the elastic sealing abutment of the elastic member 41 utilizes the deformation of the elastic member 41 to achieve a good seal between the shell 1 and the camera 2. In addition, the aforementioned sealed abutment will not generate excessive pressure on the camera, thereby not damaging the camera 2 or causing poor imaging of the camera 2.

[0026] See also Figure 2 and Figure 3 The elastic member 41 includes a trumpet-shaped sealing portion 411, and the sealing portion 411 abuts against the camera 2. Figure 3 In the embodiment, the sealing portion 411 is a horn that increases in size toward the lens 3 (in Figure 3 In some embodiments, the sealing portion may be a flared portion that grows larger away from the lens 3 (inclined outward). In comparison, an inward tilt provides a more reliable seal because an outward tilt could cause the sealing portion 411 to deform and abut against the corner 21 formed by the top and side edges of the camera 2, resulting in poor sealing.

[0027] As set up above, the elastic member 41 includes a trumpet-shaped sealing portion 411. The sealing position that cooperates with the camera 2 can be designed to be closer to the edge of the camera 2, reducing the deformation of the camera 2. At the same time, the elastic member 41 deforms toward the camera 2 after deformation, ensuring the sealing effect and better preventing water vapor from entering, so that the lens 3 does not fog.

[0028] See also Figure 2 and Figure 3 The elastic member 41 is a silicone member, for example, a silicone member with a hardness of 30 is selected.

[0029] As described above, since the elastic member 41 is a silicone member, which has a certain hardness, it can meet the strength requirements of the sealing structure while not exerting excessive pressure on the camera 2. When the silicone member has the trumpet-shaped sealing portion 411, the silicone deforms to ensure a good seal between the housing 1 and the camera 2, thereby ensuring a good sealing effect and better preventing moisture from entering, thereby preventing the lens 3 from fogging.

[0030] See also Figure 1 、 Figure 2 and Figure 3 The first moisture barrier 4 further includes a support member 42. The support member 42 is assembled with the elastic member 41 and bonded to the housing 1. The bonding method is not limited to adhesive bonding. The material of the support member 42 is not limited, for example, PET. The thickness of the support member 42 is not limited, for example, the thickness is T, 0.15mm≤T≤0.3mm.

[0031] As described above, since the first vapor barrier 4 includes the elastic member 41, the support member 42 is provided to increase the strength of the first vapor barrier 4, thereby facilitating the handling of the first vapor barrier 4. Furthermore, the support member 42 enhances the hardness of the first vapor barrier 4 and facilitates the bonding of the first vapor barrier 4 to the housing 1.

[0032] In some embodiments, the support member 42 is bonded to the housing 1 by a double-sided adhesive tape 43. In some embodiments, the support member 42 can also be bonded to the housing 1 by glue.

[0033] As described above, the double-sided tape 43 or glue is used for bonding, and the sealing effect between the first water vapor barrier 4 and the housing 1 is good. In addition, in some cases, the double-sided tape 43 is a foam adhesive to absorb tolerances and ensure the sealing effect.

[0034] See also Figure 1 The support member 42 is annular and surrounds the elastic member 41. Based on the supporting function of the support member 42, the support member 42 is not limited to an annular shape.

[0035] As described above, since the support member 42 is annular, the circumference of the elastic member 41 is supported and can better play a supporting role, thereby ensuring the strength of the first water vapor insulation member 4.

[0036] In some embodiments, the double-sided adhesive is foam adhesive with a thickness of t, 0.1 mm ≤ t ≤ 0.2 mm, and a width of w, 1.2 mm ≤ w ≤ 2 mm.

[0037] See also Figure 1 、 Figure 2 and Figure 3 The second water vapor insulating member 5 is made of foam glue. Alternatively, the second water vapor insulating member 5 is formed by curing glue.

[0038] As described above, the lens 3 is in direct contact with the outside world, placing higher demands on sealing. Since the second vapor barrier 5 is made of foam adhesive, the foam adhesive absorbs structural tolerances to ensure double-sided adhesive activation, ensuring a strong seal and meeting higher sealing requirements. Of course, the second vapor barrier 5 is formed by curing glue, which also provides a good seal and meets higher sealing requirements.

[0039] See also Figure 1 、 Figure 2 and Figure 3 The camera assembly includes a filler 6, which is fixed to the housing 1 and positioned within the cavity 10. The placement of the filler 6 within the cavity 10 is not limited; for example, the filler 6 is secured to the housing 1 via glue 7. In the embodiment of the present application, the filler 6 is made of plastic. However, any material is acceptable, as long as it provides a filling function to reduce the camera assembly's volume. The filler 6 can be made of a lightweight material to reduce the weight of the camera assembly.

[0040] The seal formed by the first and second vapor barriers 4 and 5 separates the external environment from the cavity 10. The volume of cavity 10 and the initial internal environment jointly determine its initial absolute moisture content. Reducing the volume of cavity 10 can reduce this absolute moisture content. This, combined with the previously mentioned assembly environment requirements, allows the lens to remain fog-free even in environments with large temperature fluctuations (40°C to 45°C). In this configuration, the filler 6 is located within cavity 10. Compared to a cavity 10 without a filler, the presence of filler 6 reduces the volume of cavity 10, improving the lens's resistance to fogging and enabling the lens to remain fog-free even in high humidity and large temperature fluctuations. Another purpose of filler 6 is to prevent shrinkage of the housing 1. Due to the camera's design, the housing 1 has thick areas of glue. To prevent shrinkage from affecting the sealing interface, glue must be locally reduced to ensure dimensional accuracy. Reducing glue increases the volume of cavity 10, necessitating filler 6 to prevent shrinkage.

[0041] See also Figure 2 and Figure 3 The camera 2 includes a camera head 22 that forms the cavity 10. The camera head 22 is referenced to the lens 3. The portion of the camera 2 closest to the lens 3 is the camera head, while the portion farther from the lens 3 is the camera tail. The filler 6 is annular (referred to as a filler ring) and passes through the camera head 22.

[0042] As configured above, since the filling piece 6 is annular and is passed through by the camera head 22 , the filling piece 6 fills a larger portion, thereby better playing the aforementioned role of reducing the volume of the cavity 10 .

[0043] In a second aspect, the present application discloses an electronic device. The electronic device includes any of the aforementioned camera assemblies. The electronic device is not limited to, for example, a mobile phone, a tablet computer, and the like.

[0044] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of this application shall be included in the scope of protection of this application.
