Description

Technical Field

[0001] This application relates to the field of image acquisition device technology, specifically to a protective cover, camera module and electronic terminal. Background Technology

[0002] Infrared camera modules are primarily used for image capture in nighttime or low-light environments. In electronic terminals such as vehicles, infrared camera modules installed inside vehicles can monitor the driver's status in real time, thereby improving intelligent driving. Current infrared camera modules mainly consist of a protective housing assembly, a lens, and an infrared supplementary lighting component. The protective housing assembly mainly includes a light-transmitting cover, a light-shielding cover, a lens light-shielding cover, and a supplementary lighting cover. The lens light-shielding cover and the supplementary lighting cover are positioned between the light-transmitting cover and the protective housing to respectively shield the lens and the infrared supplementary lighting component, reducing stray light interference with image quality.

[0003] However, the independent design of the light-transmitting components, protective cover, lens hood, and supplementary light hood makes the disassembly and assembly of the protective cover assembly cumbersome, increases the difficulty of disassembling and assembling the infrared camera module, and results in high disassembly and assembly costs. Utility Model Content

[0004] In view of the above, it is necessary to provide a protective cover, camera module and electronic terminal to reduce disassembly and assembly costs.

[0005] One embodiment of this application provides a protective cover, including a mounting component, an adhesive component, and a light-transmitting component. The mounting component has a first through hole and a second through hole. The first through hole is configured to mount a lens, and the second through hole is configured to mount an infrared supplementary light component. The adhesive component is disposed on the mounting component and has a first light-transmitting hole and a second light-transmitting hole. The first light-transmitting hole is adapted to and correspondingly disposed with the first through hole, and the second light-transmitting hole is adapted to and correspondingly disposed with the second through hole. The light-transmitting component is disposed on the adhesive component and covers the first light-transmitting hole and the second light-transmitting hole.

[0006] In the aforementioned protective cover, the first through hole on the mounting component and the first light-transmitting hole on the adhesive component are adapted and correspondingly set to enable the lens to capture an image. The second through hole on the mounting component and the second light-transmitting hole on the adhesive component are adapted and correspondingly set to allow the infrared light emitted by the infrared supplementary light component to pass through. The adhesive component is connected between the mounting component and the light-transmitting component to achieve a fixed connection between the mounting component and the light-transmitting component, thereby reducing the difficulty of disassembling and assembling the protective cover and thus reducing the disassembly and assembly costs of the protective cover.

[0007] In some embodiments, the mounting member has a first groove and a second groove arranged opposite to each other, a first through hole and a second through hole are both formed on the bottom wall of the first groove and respectively communicate with the second groove, and the adhesive member and the light-transmitting member are both provided in the second groove.

[0008] The first groove provides a limiting space for the light-transmitting component, thereby improving the installation efficiency of the light-transmitting component. The second groove provides a limiting space for the lens and infrared filler component, thereby improving the installation efficiency of the lens and infrared filler component.

[0009] In some embodiments, the depth of the first groove is greater than the depth of the second groove. By setting the depth of the first groove to be greater than the depth of the second groove, the installation space for the light-transmitting component, lens, and infrared supplementary light component can be reasonably arranged, which is beneficial for the miniaturization of the protective cover.

[0010] In some embodiments, the adhesive and the light-transmitting element are respectively clearance-fitted with the sidewalls of the second groove. With this arrangement, a space for movement can be formed between the sidewalls of the adhesive and the second groove, and between the light-transmitting element and the sidewalls of the second groove, preventing the adhesive from overflowing into the second groove due to high-temperature liquefaction.

[0011] In some embodiments, the distance between the adhesive and the sidewall of the second groove is greater than the distance between the light-transmitting element and the sidewall of the second groove.

[0012] The above settings can prevent the bonded parts from overflowing into the light-transmitting parts due to high-temperature liquefaction.

[0013] In some embodiments, the first light-transmitting hole and the first through hole are coaxially arranged, and the inner diameter of the first light-transmitting hole is larger than the inner diameter of the first through hole.

[0014] The above settings prevent the adhesive from blocking the light passing through the first through hole.

[0015] In some embodiments, the second light-transmitting hole and the second through hole are coaxially arranged, and the inner diameter of the second light-transmitting hole is larger than the inner diameter of the second through hole.

[0016] The above settings prevent the adhesive from blocking light passing through the second through hole.

[0017] In some embodiments, the distance between the surface of the light-transmitting element facing away from the adhesive and the bottom wall of the second groove is less than or equal to the depth of the second groove.

[0018] The above configuration allows the light-transmitting component to be completely housed in the second groove, preventing external components from colliding with the light-transmitting component and thus improving its service life.

[0019] One embodiment of this application also provides a camera module, including a lens, an infrared filler, and the aforementioned protective cover. The lens is mounted on the protective cover and is correspondingly disposed with a first through hole, while the infrared filler is mounted on the protective cover and is correspondingly disposed with a second through hole.

[0020] In the protective cover of the aforementioned camera module, the first through hole on the mounting component and the first light-transmitting hole on the adhesive component are adapted and correspondingly set to enable the lens to capture an image. The second through hole on the mounting component and the second light-transmitting hole on the adhesive component are adapted and correspondingly set to allow the infrared light emitted by the infrared supplementary light component to pass through. The adhesive component is connected between the mounting component and the light-transmitting component to achieve a fixed connection between the mounting component and the light-transmitting component, reducing the difficulty of disassembling and assembling the protective cover, thereby reducing the disassembly and assembly cost of the camera module.

[0021] An embodiment of this application also provides an electronic terminal, including a housing and the aforementioned camera module, wherein the camera module is mounted on the housing.

[0022] In the protective cover of the aforementioned electronic terminal, the first through hole on the mounting component and the first light-transmitting hole on the adhesive component are adapted and correspondingly set to enable the lens to capture an image. The second through hole on the mounting component and the second light-transmitting hole on the adhesive component are adapted and correspondingly set to allow the infrared light emitted by the infrared supplementary light component to pass through. The adhesive component is connected between the mounting component and the light-transmitting component to achieve a fixed connection between the mounting component and the light-transmitting component, thereby reducing the difficulty of disassembling and assembling the protective cover and reducing the disassembly and assembly costs of the electronic terminal.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0031] The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0032] Please see Figure 1 and Figure 2 One embodiment of this application provides a protective cover 100, including a mounting member 110, an adhesive member 120, and a light-transmitting member 130. The mounting member 110 has a first through hole 110a and a second through hole 110b. The first through hole 110a is configured to mount a lens, and the second through hole 110b is configured to mount an infrared supplementary light member. The adhesive member 120 is disposed on the mounting member 110 and has a first light-transmitting hole 120a and a second light-transmitting hole 120b. The first light-transmitting hole 120a is adapted to and correspondingly disposed with the first through hole 110a, and the second light-transmitting hole 120b is adapted to and correspondingly disposed with the second through hole 110b. The light-transmitting member 130 is disposed on the adhesive member 120 and covers the first light-transmitting hole 120a and the second light-transmitting hole 120b.

[0033] It should be noted that the first light-transmitting hole 120a and the first through hole 110a being adapted and correspondingly set means that the shape of the first light-transmitting hole 120a is the same as the shape of the first through hole 110a, and after the adhesive 120 is installed to the mounting part 110, the first light-transmitting hole 120a and the first through hole 110a are axially corresponding to each other in the first through hole 110a. The second light-transmitting hole 120b and the second through hole 110b being adapted and correspondingly set means that the shape of the second light-transmitting hole 120b is the same as the shape of the second through hole 110b, and after the adhesive 120 is installed to the mounting part 110, the second light-transmitting hole 120b and the second through hole 110b are axially corresponding to each other in the second through hole 110b. The number of second through holes 110b can be multiple, and the multiple second through holes 110b are arranged at intervals. The number of second light-transmitting holes 120b can be single, that is, the multiple second through holes 110b are all located in the second light-transmitting hole 120b. The number of second light-transmitting holes 120b can also be multiple, and the multiple second light-transmitting holes 120b are arranged in a one-to-one correspondence with the multiple second through holes 110b.

[0034] In the aforementioned protective cover 100, the first through hole 110a on the mounting component 110 and the first light-transmitting hole 120a on the adhesive component 120 are adapted and correspondingly set to enable the lens to capture an image. The second through hole 110b on the mounting component 110 and the second light-transmitting hole 120b on the adhesive component 120 are adapted and correspondingly set to allow the infrared light emitted by the infrared supplementary light component to pass through. The adhesive component 120 is connected between the mounting component 110 and the light-transmitting component 130 to achieve a fixed connection between the mounting component 110 and the light-transmitting component 130, thereby reducing the difficulty of disassembling and assembling the protective cover 100 and thus reducing the disassembly and assembly cost of the protective cover 100.

[0035] Please see Figure 2 and Figure 3 In some embodiments, the mounting member 110 has a first groove 110c and a second groove 110d that are arranged opposite to each other. The first through hole 110a and the second through hole 110b are both opened on the bottom wall of the first groove 110c and respectively connect to the second groove 110d. The adhesive member 120 and the light-transmitting member 130 are both provided in the second groove 110d.

[0036] The first groove 110c provides a limiting space for the light-transmitting component 130, thereby improving the installation efficiency of the light-transmitting component 130. The second groove 110d provides a limiting space for the lens and the infrared fill light component, thereby improving the installation efficiency of the lens and the infrared fill light component.

[0037] Please see Figure 3 In some embodiments, the depth of the first groove 110c is greater than the depth of the second groove 110d. By setting the depth of the first groove 110c to be greater than the depth of the second groove 110d, the installation space for the light-transmitting component 130, the lens, and the infrared supplementary light component can be reasonably arranged, which is beneficial to the miniaturization of the protective cover 100.

[0038] In some embodiments, the adhesive 120 and the light-transmitting element 130 are respectively clearance-fitted with the sidewalls of the second groove 110d. Through this arrangement, movable spaces can be formed between the adhesive 120 and the sidewalls of the second groove 110d, and between the light-transmitting element 130 and the sidewalls of the second groove 110d. This prevents the adhesive 120 from overflowing into the second groove 110d due to high-temperature liquefaction, thereby improving the aesthetics of the protective cover 100.

[0039] In some embodiments, the distance between the adhesive 120 and the sidewall of the second groove 110d is greater than the distance between the light-transmitting element 130 and the sidewall of the second groove 110d.

[0040] The above-mentioned design prevents the adhesive 120 from overflowing into the light-transmitting part 130 due to high-temperature liquefaction, thereby improving the aesthetics of the protective cover 100.

[0041] Please see Figure 3 In some embodiments, the first light-transmitting hole 120a and the first through hole 110a are coaxially arranged, and the inner diameter of the first light-transmitting hole 120a is larger than the inner diameter of the first through hole 110a.

[0042] With the above settings, the adhesive 120 can be prevented from blocking the light passing through the first through hole 110a.

[0043] In some embodiments, the second light-transmitting hole 120b and the second through hole 110b are coaxially arranged, and the inner diameter of the second light-transmitting hole 120b is larger than the inner diameter of the second through hole 110b.

[0044] With the above settings, the adhesive 120 can be prevented from blocking the light passing through the second through hole 110b.

[0045] Please see Figure 3 In some embodiments, the distance between the surface of the light-transmitting element 130 facing away from the adhesive element 120 and the bottom wall of the second groove 110d is less than or equal to the depth of the second groove 110d.

[0046] With the above arrangement, the light-transmitting element 130 can be completely housed in the second groove 110d, avoiding collisions between external components and the light-transmitting element 130, which helps to improve the service life of the light-transmitting element 130.

[0047] Please see Figure 4 One embodiment of this application also provides a camera module 200, including a lens 210, an infrared filler element 220, and the aforementioned protective cover 100. The lens 210 is mounted on the protective cover 100 and is correspondingly disposed with the first through hole 110a. The infrared filler element 220 is mounted on the protective cover 100 and is correspondingly disposed with the second through hole 110b. The camera module 200 can be used for driver status monitoring.

The second through hole 110b on the mounting member 110 and the second light-transmitting hole 120b on the adhesive member 120 are adapted and correspondingly set to transmit infrared light emitted by the infrared supplementary light member 220. The adhesive member 120 is connected between the mounting member 110 and the light-transmitting member 130 to achieve a fixed connection between the mounting member 110 and the light-transmitting member 130, thereby reducing the difficulty of disassembling and assembling the protective cover 100 and thus reducing the disassembly and assembly cost of the camera module 200.
