[0028] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.
[0029] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which this application belongs.
[0030] The technical solution of the embodiment of the present application is to solve the above technical problems, and the overall idea is as follows:
[0031] Example 1
[0032] Reference Figure 1 and attached Figure 2 The electronic device provided in an embodiment of the present application includes a shell 1, a camera assembly 2 and a transparent cover plate 3, wherein the shell 1 includes a revealing window 11; the camera assembly 2 is fixed in the shell 1, and the lens 21 of the camera assembly 2 is revealed through the revealing window 11; the transparent cover plate 3 is arranged corresponding to the revealing window 11, and a closed space is formed between the transparent cover plate 3 and the top surface of the lens 21 of the camera assembly 2, and the transparent cover plate 3 includes an isolation layer 31 to isolate the temperature of the transparent cover plate 3 away from the lens assembly 2.
[0033] Specifically, in order to solve the problem in the prior art that when the lens enters a low-temperature environment from a high-temperature environment, water mist is easily generated, which affects the use, the electronic device provided in this embodiment sets an isolation layer 31 in the transparent cover plate 3 of the corresponding lens assembly 2, so that the isolation layer 31 can isolate the low-temperature gas outside the electronic device from being transmitted through the transparent cover plate 3 to the inner surface of the transparent cover plate 3 and contacting the higher temperature gas in the enclosed space, thereby preventing condensation on the inner wall of the transparent cover plate 3 to produce water mist, thereby effectively ensuring the clarity of the lens 21 during the image acquisition process and improving the user experience.
[0034] The electronic device provided in this embodiment may be, but is not limited to, a mobile phone, a camera, a laptop computer, a tablet computer, or other electronic device structure with a camera.
[0035] Among them, the shell 1 is a rigid structure, which is the overall appearance structure of the electronic device. The specific shape and size can be designed and adjusted according to actual needs. For example, when the electronic device is a mobile phone, the shell 1 can be, but not limited to, a rectangular trough or a cuboid structure, which can be, but not limited to, a metal material or a hard plastic material. The shape and size of the revealing window 11 on the shell 1 can be designed and adjusted according to actual needs, such as a rectangle or a circle, as long as it can cooperate with the camera assembly 2 to reveal the lens 21 to realize image acquisition. For a mobile phone, the revealing window 11 can be, but not limited to, opened in the upper part or the middle part of the back of the shell 1. The camera module 2 is fixedly arranged in the shell 1, and can be installed by, but not limited to, bonding, screwing, etc. This setting can be easily understood by those skilled in the art, and will not be repeated here; the lens 21 of the camera module 2 can be kept inside the shell 1 corresponding to the revealing window 11, or can be kept in a state of extending out of the shell 1. The lens 21 of the camera module 2 can also be extended relative to the shell 1 through the revealing window 11 so as to be able to enter and exit the shell 1, and the camera module 2 is sealed and connected to the circumferential inner wall of the revealing window 11.
[0036] Among them, the transparent cover plate 3 is a rigid structure, which can transmit light so as not to affect the image acquisition of the lens 21, and can be colorless and transparent or colored and transparent; the transparent cover plate 3 can be but not limited to transparent glass material; in this embodiment, an isolation layer 31 is arranged in the transparent cover plate 3, and the isolation layer 31 has the properties of heat insulation and light transmission; the transparent cover plate 3 can be an isolation layer 31 arranged between double-layer glass, or the isolation layer 31 can be set as the outermost layer of the transparent cover plate 3; in this embodiment, the transparent cover plate 3 is sealed and connected with the shell 1, and can be but not limited to sealing and bonding with the edge of the shell 1 or the exposure window 11 through foam, so that the space between the transparent cover plate 3 and the top surface of the lens 21 forms a closed space, and then when the electronic device enters the environment with a higher temperature from the environment with a lower temperature, even if the gas in the closed space maintains a higher temperature, the low-temperature gas outside the transparent cover plate 3 will not pass through the transparent cover plate 3 to contact the gas with a higher temperature, and then no water droplets condensation, i.e., water mist, will be generated on the inner wall of the transparent cover plate 3, and the image acquisition of the lens 21 will not be affected. In this embodiment, the light-transmitting cover plate 3 can also be Figure 1 As shown, the inner wall of the exposure window 11 is sealed with the circumferential outer wall, and a supporting ring 12 can also be set at the exposure window 11. A supporting step is set on the supporting ring 12 to support the light-transmitting glass 3, and then the bottom and side surfaces of the light-transmitting glass 3 need to maintain a sealed connection with the supporting steps of the supporting ring 12.
[0037] According to the above, the electronic device provided by the present application, by setting an isolation layer 31 in the transparent cover plate 3, enables the isolation layer 31 to isolate the temperature on the side away from the lens 21, prevents the low temperature outside the lens 21 from quickly passing through the cover plate in a short time to affect the higher temperature air in the enclosed space, and avoids high and low temperature airflows from contacting the inner surface of the transparent cover plate 3 in a short time to cause condensation of water vapor, effectively improving the user experience of the lens 21 and even the entire device; thereby solving the problem in the prior art that when the lens enters a low temperature environment from a high temperature environment, water mist is easily generated to affect the use.
[0038] The term "and / or" in this article is merely a description of the association relationship of associated objects, indicating that three relationships may exist, for example, A and / or B, which is specifically understood as: A and B may be included at the same time, A may exist alone, or B may exist alone, and any of the above three situations may exist.
[0039] Further, see Attachment Figure 1 In the electronic device provided in this embodiment, in a specific implementation, the light-transmitting cover plate 3 includes at least a first cover plate 32 and a second cover plate 33, the first cover plate 32 and the second cover plate 33 are stacked and spaced apart, and the isolation layer 31 is disposed between the first cover plate 32 and the second cover plate 33.
[0040] Specifically, in order to ensure the strength and service life of the light-transmitting cover plate 3, in this embodiment, the light-transmitting cover plate 3 is set to include at least a first cover plate 32 and a second cover plate 33. The first cover plate 32 and the second cover plate 33 are both light-transmitting rigid glass cover plates, and an isolation layer 31 is set between the two, so that the first cover plate 32 and the second cover plate 33 can become a protective layer for the isolation layer 31, thereby improving the overall strength of the light-transmitting cover plate 3, and can also extend the contact path of high and low temperature gases to a certain extent, and reduce the probability of water mist formation. The first cover plate 32 and the second cover plate 33 are equal in size and thickness, and the required light transmittance of the lens 21 is ensured; the isolation layer 31 can be set to be the same size as the first cover plate 32 and the second cover plate 33, or it can only correspond to the position of the lens 21. In this embodiment, the light-transmitting cover plate 3 can also include a larger number of glass cover plates to improve the strength and thermal insulation effect of the light-transmitting cover plate 3.
[0041] Further, see Attachment Figure 1 In the electronic device provided in this embodiment, in a specific implementation, the isolation layer 31 is a transparent colloid; or the isolation layer 31 is a vacuum layer.
[0042] Specifically, in order to achieve that the isolation layer 31 is both light-transmitting and heat-insulating, in this embodiment, the isolation layer 31 can be set as a transparent colloid or a vacuum layer; when the isolation layer 31 is set as a transparent colloid, it can be but not limited to optical adhesive (OCA, Optical Clear Adhhesive), which has a high light transmittance and heat-insulating properties. At the same time, setting the isolation layer 31 as OCA colloid can also bond the first cover plate 32 and the second cover plate 33 to each other to improve the overall strength of the light-transmitting cover plate 3; when the isolation layer 31 is set as a vacuum layer, it is necessary to seal the first cover plate 32, the second cover plate 33 and the shell 1, so that a vacuum enclosed space is formed between the first cover plate 32 and the second cover plate 33, and there is no gas or even sound propagation medium inside, so that the temperature of the high-temperature gas cannot be transmitted to the lens 21 side through the vacuum layer.
[0043] Further, see Attachment Figure 1 In the electronic device provided in this embodiment, in a specific implementation, the light-transmitting cover plate 3 also includes a third cover plate (not shown in the figure); the third cover plate and the first cover plate 32 and the second cover plate 33 are stacked in sequence and arranged at intervals, and the isolation layer 31 is provided between adjacent cover plates.
[0044] Specifically, in order to improve the strength of the light-transmitting cover plate 3, a third cover plate may be provided in the present embodiment. The third cover plate is also a rigid light-transmitting glass cover plate. An isolation layer 31 is provided between adjacent cover plates, that is, two spaced isolation layers 31, to further improve the thermal insulation effect. The two isolation layers 31 may be the same or different. For example, both may be OCA colloids, both may be vacuum layers, or one may be OCA colloid and the other may be a vacuum layer. The specific setting methods are as follows:
[0045] The first type is that at least one of the isolation layer 31 between the third cover plate and the first cover plate 32 and the isolation layer 31 between the first cover plate 32 and the second cover plate 33 is a transparent colloid. That is, the isolation layer 31 between the third cover plate and the first cover plate 32 is an OCA colloid, and the isolation layer 31 between the first cover plate 32 and the second cover plate 33 is a vacuum layer, or the isolation layer 31 between the first cover plate 32 and the second cover plate 33 is an OCA colloid, and the isolation layer 31 between the third cover plate and the first cover plate 32 is a vacuum layer, or the isolation layer 31 between the third cover plate and the first cover plate 32 and the isolation layer 31 between the first cover plate 32 and the second cover plate 33 are both OCA colloids.
[0046] The second type: at least one of the isolation layer 31 between the third cover plate and the first cover plate 32 and the isolation layer 31 between the first cover plate 32 and the second cover plate 33 is a vacuum layer. That is, the isolation layer 31 between the third cover plate and the first cover plate 32 is a vacuum layer, and the isolation layer 31 between the first cover plate 32 and the second cover plate 33 is an OCA colloid, or the isolation layer 31 between the first cover plate 32 and the second cover plate 33 is a vacuum layer, and the isolation layer 31 between the third cover plate and the first cover plate 32 is an OCA colloid, or the isolation layer 31 between the third cover plate and the first cover plate 32 and the isolation layer 31 between the first cover plate 32 and the second cover plate 33 are both vacuum layers.
[0047] Of course, it is understandable that after the number of glass cover layers is increased, the isolation layer 31 can also be reasonably matched according to the above settings, and no further details will be given here.
[0048] Furthermore, in the electronic device provided in this embodiment, in a specific implementation, the sum of the thicknesses of the first cover plate 32 , the second cover plate 33 , and the isolation layer 31 is a specified thickness.
[0049] Specifically, in order to ensure the strength and design specifications of the light-transmitting cover plate 3, in this embodiment, the sum of the thicknesses of the first cover plate 32, the second cover plate 33 and the isolation layer 31 is a specified thickness, for example: the sum of the thicknesses is 0.5 mm or 0.8 mm; wherein the thicknesses of the first cover plate 32 and the second cover plate 33 may be the same or different, for example: when the light-transmitting cover plate 3 only includes the first cover plate 32, the second cover plate 33 and the isolation layer 31, the thicknesses of the first cover plate 32 and the second cover plate 33 may be 0.2 mm respectively, and the isolation layer 31 may be 0.1 mm; the thickness of the first cover plate 32 may also be set to 0.1 mm, and the thicknesses of the second cover plate 33 and the isolation layer 31 may be 0.2 mm respectively.
[0050] Further, see Attachment Figure 3 and attached Figure 4 In the electronic device provided in this embodiment, in a specific implementation, the transparent cover plate 3 also includes an adhesive layer 34; the orthographic projection of the isolation layer 31 along the first direction a completely coincides with the orthographic projection of the lens 21 of the lens assembly 2 along the first direction a; the first direction a is the direction in which the first cover plate 32 and the second cover plate 33 are stacked; the adhesive layer 34 is arranged around the isolation layer 31, and the first cover plate 32 and the second cover plate 33 are bonded to the two sides of the adhesive layer 34 respectively.
[0051] Specifically, because the vacuum design is difficult, in order to reduce the difficulty of design and processing, in this embodiment, an adhesive layer 34 is set in the form of a vacuum layer for the isolation layer 31, and the isolation layer 31 is set to a smaller area, which is only set corresponding to the lens 21. The adhesive layer 34 is set around the isolation layer 31 to ensure that the image acquisition area of the lens 21 will not generate water. At the same time, the first cover plate 32 and the second cover plate 33 are bonded by the adhesive layer, which can not only improve the strength of the transparent cover plate 3 but also seal the isolation layer 31; it can be understood that the adhesive layer 34 in this embodiment can be but not limited to the aforementioned optical glue, which can also be light-transmitting and heat-insulating, and thus the processing area of the vacuum layer can be reduced while ensuring heat insulation, thereby reducing the difficulty of processing. It can be understood that the vacuum layer and the OCA colloid can be alternately arranged along the radial direction of the exposure window 11.
[0052] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
