Description

Technical Field

[0001] The utility model relates to the technical field of cameras, and particularly relates to a fixed-focus camera with a sealed cover. Background Art

[0002] In electronic devices with a camera function, fixed-focus cameras are often equipped. Common fixed-focus cameras are as Figure 1 and Figure 2 shown. There are petals 2 on the lens of the camera 1. When the camera 1 is assembled with the housing 8, there is a gap 4 at the assembly and mating part with the main body 3 of the housing 8. As can be seen from the Figure 3 sectional view, the edge of the lens at the upper part of the camera 1 has a stepped structure, and it is sealed and isolated from the housing 8 by a sealing foam 9. There is a gap 4 between the sealing foam 9 and the lens. The lower part of the camera 1 is installed on a support pad 10 with medium hardness, and the support pad 10 is fixed on the support base 11. When the distance between the lens of the camera and the lens 6 is relatively far, in order not to affect the viewing angle 7 of the camera, the visible area of the lens 6 is relatively large, and the black edge 12 of the lens 6 can block the internal structure of the housing. However, users can see the internal structures of the camera 1 such as the petals 2, the gap 4, and the steps from the visible area of the lens 6, which affects the overall appearance effect of the product. Moreover, if the sealing performance of the lens 6 or the sealing foam 9 gradually deteriorates during use, dust and moisture are likely to enter the main board of the electronic device, affecting other functions of the whole machine.

[0003] Therefore, the existing technology still needs to be improved. Content of the Utility Model

[0004] In view of the deficiencies of the above-mentioned existing technology, the purpose of the utility model is to provide a fixed-focus camera with a sealed cover, so as to solve the problems that the internal structure of the existing fixed-focus camera can be seen from the visible area of the lens, affecting the appearance effect, and the sealing performance deterioration affects the functions of the whole electronic device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A fixed-focus camera with a sealed cover includes a camera, a lens, and a housing. Among them, a soft rubber sleeve is sleeved on the stepped surface of the lens of the camera, the housing is sleeved on the camera and is closely attached to the soft rubber sleeve, the lens is fixed in the lens groove on the surface of the housing, and the soft rubber sleeve covers the petals on the lens and fully wraps and seals the stepped surface of the camera.

[0007] In the fixed-focus camera with a sealed cover, the soft rubber sleeve includes a bottom sleeve ring and a top sleeve ring located on the surface of the bottom sleeve ring. The bottom sleeve ring and the top sleeve ring are integrally formed, and a round hole opened in the middle of the top surface of the top sleeve ring is used to expose the lens of the camera.

[0008] In the aforementioned sealed fixed-focus camera, the outer side of the top sleeve and the top plane of the bottom sleeve form an L-shaped stepped surface, which is adapted to the bending part on the inner side of the housing.

[0009] In the aforementioned sealed fixed-focus camera, the inner surfaces of the top and bottom sleeves form a two-fold stepped surface, which is adapted to the stepped surface of the camera.

[0010] In the aforementioned sealed fixed-focus camera, an interference fit of 0.05 to 0.15 mm is reserved between the two stepped surfaces and the stepped surface of the camera.

[0011] In the aforementioned sealed fixed-focus camera, the top surface of the top sleeve is a downwardly inclined surface at a preset angle.

[0012] Compared to existing technologies, the sealed fixed-focus camera provided by this utility model includes a camera, a lens, and a housing. A soft rubber sleeve is fitted onto the stepped surface of the camera lens. The housing is fitted onto the camera and tightly adheres to the soft rubber sleeve. The lens is fixed in a lens groove on the surface of the housing. The soft rubber sleeve covers the petals on the lens and completely seals the stepped surface of the camera. By fitting the soft rubber sleeve onto the stepped surface, the gap between the lens and the housing is filled while covering the petals on the lens. The internal structures such as petals, gaps, and steps are not visible from the visible area of ​​the lens. This reduces the exposed area of ​​the camera without affecting the camera's viewing angle, thereby improving the appearance of the camera lens. At the same time, the soft rubber sleeve fills all gaps between the housing and the camera, preventing dust and moisture from entering the motherboard of the electronic device even if the lens sealing deteriorates, thus avoiding affecting other functions of the device.

[0019] This utility model provides a sealed, covered fixed-focus camera. To make the objectives, technical solutions, and advantages of this utility model clearer and more explicit, the following detailed description, with reference to the accompanying drawings and embodiments, further illustrates the utility model. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this utility model.

[0020] Please also refer to Figure 4 and Figure 5 This utility model provides a sealed and covered fixed-focus camera, which is installed on electronic devices such as mobile phones. The fixed-focus camera includes a conventional camera 1, a lens 6, and a housing 8 (the structure relevant to this embodiment is mainly described here, and other structures such as the support pad 10 and the support base 11 are not described in detail). A soft rubber sleeve 13 is fitted on the stepped surface of the lens of the camera 1. The housing 8 is fitted on the camera 1 and is tightly attached to the soft rubber sleeve 13. The lens 6 is fixed in the lens groove on the surface of the housing 8. The soft rubber sleeve 13 covers the petals on the lens and completely seals the stepped surface of the camera 1.

[0021] By covering the stepped surface of camera 1 with a soft rubber sleeve 13, the petals on the lens are covered while filling the gap between the lens and the housing. The internal structure of camera 1, such as petals 2, gaps 4, and steps, will not be visible from the visible area of ​​lens 6. This reduces the exposed area of ​​the camera without affecting the camera's viewing angle, thereby improving the appearance of the camera lens. At the same time, the soft rubber sleeve 13 fills all the gaps between the housing and the camera, so even if the lens seal deteriorates, dust and moisture will not enter the motherboard, thus avoiding affecting other functions of the device.

[0022] In this embodiment, the soft rubber sleeve 13 includes a bottom sleeve 131 and a top sleeve 132 located on the surface of the bottom sleeve 131. The bottom sleeve 131 and the top sleeve 132 are integrally formed, and the round hole in the middle of the top surface of the top sleeve 132 is used to expose the lens of the camera.

[0023] Please refer to the following: Figure 6The diameter of the top sleeve 132 is smaller than that of the bottom sleeve 131. The vertical outer side of the top sleeve 132 and the top plane of the bottom sleeve 131 form an L-shaped stepped surface 133, which is adapted to the bending part on the inner side of the housing. The inner side of the soft rubber sleeve 13 is composed of the inner sides of the top sleeve 132 and the bottom sleeve 131, forming a two-fold stepped surface. This two-fold stepped surface is adapted to the stepped surface of the camera 1, so that the inner side of the soft rubber sleeve 13 fits snugly against the outer side of the camera, completely covering the upper part of the camera 1. For ease of assembly, a 0.05-0.15mm interference fit is reserved on one side between the inner side of the soft rubber sleeve 13 and the outer side of the camera to ensure that it will not fall off during pre-assembly. During assembly, the soft rubber sleeve 13 is first pre-assembled on the camera 1, and then the whole assembly is installed into the housing.

[0024] The outer vertical surface of the bottom sleeve 131 is flush with the outer vertical surface of the camera to prevent the soft rubber sleeve 13 from lifting the housing and affecting assembly.

[0025] The top surface of the top collar 132 is a downward-sloping inclined surface 134 at a preset angle greater than the camera's viewing angle (e.g., 30 degrees). This structure with a large-angle opening, such as... Figure 4 As shown, there should be a gap of more than 0.2mm between the camera and the viewing angle 7 to avoid blocking the camera's view and affecting the photo quality.

[0026] The soft rubber sleeve 13 is preferably made of thermoplastic elastic soft materials such as silicone, TPU (Thermoplastic Urethane), and TPE (Thermoplastic Elastomer), with a hardness of generally 30 to 70A; the color is a dark color close to the lens color of the camera, such as black.

[0027] The existing support pad 10 is a medium-hardness rigid support. In specific implementation, it can also be replaced with a medium-hardness soft support, such as foam, to avoid overpressure on the camera due to tolerance accumulation.

[0028] In summary, the fixed-focus camera with a sealed cover provided by this utility model adds a soft rubber sleeve between the housing and the camera. This sleeve covers the petals at the edge of the lens and the gap between the lens and the housing, thus reducing the exposed area of ​​the lens and improving the appearance of the lens area without affecting the camera's field of view. Simultaneously, the soft rubber sleeve completely encloses the stepped surface above the camera, preventing dust and moisture from entering the motherboard even if the lens seal deteriorates, thus avoiding affecting other functions of the device.

[0029] It should be understood that the application of this utility model is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
