[0030] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0031] An embodiment of the first aspect of the present disclosure is to provide a camera combination module, as shown in Figures 2 to 5, comprising an upper cover 1, a filter holder 2, a lower cover 3 and a lens assembly 4, wherein the upper cover 1 is connected to the lower cover 3, and the filter holder 2 is arranged between the upper cover 1 and the lower cover 3, the lens assembly 4 is installed below the lower cover 3, and a dustproof cavity 31 is recessed on the side of the lower cover 3 facing the lens assembly 4, and a lens module 41 in the lens assembly 4 extends into the dustproof cavity 31, and an imaging sensor is integrated in the lens module 41.

[0032] When installing the above-mentioned camera combination module, the filter bracket 2 is assembled between the upper cover 1 and the lower cover 3, and then the upper cover 1 can be connected to the lower cover 3 by snap connection, screw connection, etc. The lower cover 3 is provided with a dustproof cavity 31, and the lens module 41 in the lens assembly 4 can be extended into the dustproof cavity 31, and finally the lens assembly 4 can be connected to the lower cover 3.

[0033] Compared to the prior art, the camera assembly module provided in the above embodiment places the upper cover 1, filter holder 2, and lower cover 3 in the front, allowing the lens module 41 to be embedded within the lower cover 3. Furthermore, the imaging sensor is integrated within the lens module 41, eliminating the need for a separate placement of the imaging sensor on the circuit board 42. This effectively reduces the height of the camera assembly module and results in a smaller overall size. Furthermore, the provision of the dustproof chamber 31 on the lower cover 3 not only reduces the height of the lens module 41 but also acts as a dustproof barrier, preventing dust from entering the space surrounding the lens module and causing adverse effects.

[0034] The structure of the lens assembly 4 is described in detail below:

[0035] In some embodiments, as shown in Figure 3, the lens assembly 4 includes a circuit board 42 and a lens module 41 mounted on the circuit board 42. The circuit board 42 is connected to the lower cover 3 to embed the lens module 41 into the dustproof cavity 31 and close the bottom opening of the dustproof cavity 31. The circuit board 42 provides power for the lens module 41.

[0036] To ensure the position accuracy between the circuit board 42 and the lower cover 3, a positioning hole 421 is opened on one of the circuit board 42 and the lower cover 3, and a positioning pin 32 is protruded from the other to penetrate into the positioning hole 421, so as to achieve accurate positioning of the two.

[0037] As shown in Figures 3 and 4, in at least one embodiment, the circuit board 42 is provided with a positioning hole 421, and there are two positioning holes 421, which are located at opposite corners of the circuit board 42. The lower cover 3 is provided with two positioning pins 32 that are inserted into the positioning holes 421 in a one-to-one correspondence.

[0038] Of course, the number of positioning holes 421 and positioning pins 32 is not limited to two, and may also be two, four, five, etc.

[0039] To enhance the sealing performance of the dustproof cavity 31 , the circuit board 42 and the lower cover 3 may be fixedly connected by colloid.

[0040] The structures of the lower cover 3 and the upper cover 1 are described in detail below:

[0041] In some embodiments, as shown in Figures 3 and 4, a lug 33 is protruded from the edge of one end of the lower cover 3 near the filter holder 2, and a connecting hole 331 is opened on the lug 33. The connecting hole 331 is configured for a fastener to pass through to fix the lower cover 3 to the panel of the product.

[0042] The fasteners may be screws, pins, etc.

[0043] In at least one embodiment, the fastener is a screw.

[0044] The above-mentioned lugs 33 can be configured as two, three, four or more. As shown in Figure 3, the lugs 33 can be configured as three, two of which are located on one side of the lower cover 3, and the remaining lug 33 is located on the other side of the lower cover 3, so that the lower cover 3 can be firmly installed on the product.

[0045] As shown in Figures 3 and 4, a first cavity 36 is recessed on the side of the lower cover 3 facing the lens assembly 4, and a second cavity 37 is recessed on the side of the lower cover 3 away from the lens assembly 4. Along the length direction of the lower cover 3, that is, the left and right direction in Figure 4, the dustproof cavity 31 is located between the first cavity 36 and the second cavity 37.

[0046] As shown in FIG3 , the lower cover 3 is provided with a first light inlet and outlet communicating with the dustproof cavity 31 , and the first light inlet and outlet are arranged opposite to the lens module 41 .

[0047] Similarly, the upper cover 1 is provided with a second light inlet and outlet arranged opposite to the first light inlet and outlet.

[0048] Specifically, the shapes of the first light inlet and outlet and the second light inlet and outlet can be adapted to the shape of the top of the lens module 41.

[0049] In at least one embodiment, as shown in FIG. 3 , the first light inlet and outlet and the second light inlet and outlet may be circular.

[0050] In some embodiments, to facilitate the disassembly of the upper cover 1 and the lower cover 3 , one of the upper cover 1 and the lower cover 3 is provided with a female buckle 11 , and the other is provided with a male buckle 34 engaged with the female buckle 11 .

[0051] Taking FIG. 3 and FIG. 4 as an example, the upper cover 1 is provided with a female buckle 11 , and the lower cover 3 is provided with a male buckle 34 engaged with the female buckle 11 .

[0052] The above-mentioned female buckles 11 can be configured in two, three, four, five, etc., and correspondingly, the male buckles 34 can also be configured in two, three, four, five, etc.

[0053] In at least one embodiment, there are four female buckles 11, two of which are arranged on one side of the upper cover 1, and the other two female buckles 11 are arranged on the other side of the upper cover 1. The male buckles 34 correspond to the female buckles 11 above and below, and are also arranged in four.

[0054] In some embodiments, as shown in FIG3 , the filter holder 2 is slidably disposed between the upper cover 1 and the lower cover 3 , thereby enabling the position of the filter on the filter holder 2 relative to the lens module 41 to be switched to different positions depending on the day and night, achieving excellent photographic effects. To ensure the sliding stability of the filter holder 2 , the upper cover 1 is provided with a first retaining structure 12 that slidably engages with one side of the filter holder 2 , and the lower cover 3 is provided with a second retaining structure 35 that slidably engages with the other side of the filter holder 2 .

[0055] Specifically, as shown in FIG3 , the first limiting structure 12 may include two first limiting ribs arranged opposite to each other. The top surface of the filter holder 2 slides with the two first limiting ribs, and the movement range of the filter holder 2 can be limited by the first limiting ribs.

[0056] Correspondingly, as shown in FIG3 , the second limiting structure 35 may also include two oppositely arranged second limiting ribs, the extension direction of the second limiting ribs being parallel to the extension direction of the first limiting ribs, and the bottom surface of the filter holder 2 slidingly cooperates with the two second limiting ribs.

[0057] A preferred embodiment of the camera assembly module is described in detail below:

[0058] In some embodiments, as shown in Figure 3, the camera assembly module also includes a buffer assembly, which is installed above the upper cover 1 or below the lens assembly 4. Of course, the buffer assembly is preferably installed above the upper cover 1 and below the lens assembly 4. The buffer assembly can play a buffering role during the product assembly process.

[0059] In some embodiments, as shown in FIG3 , the buffer assembly includes a first foam 5 , which is disposed above the upper cover 1 . The first foam 5 is also configured to prevent light inside the product from entering the camera assembly module.

[0060] When the fastener passes through the connection hole 331 to assemble the lower cover 3 to the product, the first foam 5 will be compressed and deformed under the action of pressure, preventing the light inside the product from entering the camera assembly module.

[0061] Specifically, in order to facilitate the connection of the first foam 5 , the first foam 5 is adhered to the upper cover 1 through colloid.

[0062] In addition, as shown in FIG3 , a third light inlet and outlet is provided on the first foam, which is arranged opposite to the second light inlet and outlet, and the shape of the third light inlet and outlet is the same as that of the second light inlet and outlet.

[0063] In some embodiments, the buffer assembly includes a second foam 6 , which is disposed below the lens assembly 4 .

[0064] To facilitate the connection of the second foam 6 , the second foam 6 is adhered to the bottom surface of the lens assembly 4 through colloid.

[0065] An embodiment of the second aspect of the present disclosure provides a security camera. The security camera provided by the embodiment of the second aspect of the present disclosure includes the above-mentioned camera combination module.

[0066] The security camera provided in the second aspect of the present disclosure has the camera combination module provided in the embodiment of the first aspect of the present disclosure, and thus has all the beneficial effects of the camera combination module provided in the embodiment of the first aspect of the present disclosure.

[0067] In some embodiments, the lens module 41 on the lens assembly 4 in the security camera preferably includes a lens module of a mobile phone lens.

[0068] The pixels of mobile phone lenses can reach tens of millions or even hundreds of millions of pixels, which can effectively improve the image clarity of security cameras, make the images more realistic, and improve the user experience.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them. Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present disclosure.
