[0031] Figure 1 FIG. 1 is a schematic diagram showing a lens fixing structure 100 according to an embodiment of the present utility model. Figure 2 An exploded view of a lens fixing structure 100 according to an embodiment of the present utility model is shown below. Figure 1 and Figure 2 Describe in detail.

[0032] like Figure 1 and Figure 2As shown, the lens fixing structure 100 includes a bottom shell 110, a bracket 120, a main board 130 and a lens 140, wherein the bracket 120, the main board 130 and the lens 140 constitute a lens assembly. Specifically, a second lens hole 121 is provided on the bracket 120; the main board 130 is fixedly connected to the back side of the bracket 120; the lens 140 is fixedly connected to the surface of the main board 130 by bonding, welding or the like, and extends into the second lens hole 121. The bottom shell 110 may be a metal shell or a plastic shell, and may provide an installation position and effective support and protection for the lens assembly (the bracket 120, the main board 130 and the lens 140). Specifically, the bottom shell 110 has a top plate 111 and a side wall 112, wherein the side plate is arranged around the top plate 111 and defines a receiving chamber 113 together with the top plate 111, and a first lens hole 114 is arranged on the side wall 112 of the bottom shell 110, and the lens assembly is arranged in the receiving chamber 113 and the lens 140 extends into the first lens hole 114. In addition, a first positioning portion 115 and a fixing column 116 are fixedly arranged in the bottom shell 110 (i.e., in the receiving chamber 113), and a second positioning portion 122 is arranged on the bracket 120, and the bracket 120 is screwed to the fixing column 116, and the first positioning portion 115 is plugged and matched with the second positioning portion 122. The bracket 120 and the fixing column 116 (bottom shell 110) may be fastened together by screws. By cooperating with the first positioning portion 115 and the second positioning portion 122, the relative position of the bracket 120 and the bottom shell 110 can be determined, and the bracket 120 is not easily tilted or deformed due to the locking of the screws, thereby ensuring the concentricity of the lens 140 and the first lens hole 114 and reducing the possibility of interference between the lens 140 and the bottom shell 110.

[0033] According to one embodiment of the utility model, Figure 1 and Figure 2 As shown, the first positioning portion 115 can be a square column, and the second positioning portion 122 can be a square hole that matches the square column. Through the cooperation of the square column and the square hole, the bracket 120 can be provided with stable support and positioning, ensuring that the bracket 120 is not easily tilted or deformed due to the locking of the screws. In other embodiments, the design of the first positioning portion 115 and the second positioning portion 122 can be flexibly adjusted according to actual conditions. For example, the first positioning portion 115 can be set as a square hole, and the second positioning portion 122 can be set as a square column; for another example, the first positioning portion 115 can be set as a column in a circular, triangular or other shape, and the second positioning portion 122 can be correspondingly set as a hole in a circular, triangular or other shape.

[0034] According to one embodiment of the utility model, Figure 1 and Figure 2As shown, the first positioning portion 115 and the second positioning portion 122 can be respectively provided in plurality to provide more effective support for the bracket 120 and further reduce the possibility of the bracket 120 being tilted and deformed due to the locking of the screws, for example Figure 1 In the illustrated embodiment, two first positioning portions 115 and two second positioning portions 122 are respectively provided.

[0035] According to one embodiment of the utility model, Figure 1 and Figure 2 As shown, the first positioning portion 115 can be disposed on the side wall 112 of the bottom housing 110 and adjacent to the first lens hole 114, and correspondingly, the second positioning portion 122 can be disposed on the top of the bracket 120. The above arrangement helps to ensure accurate positioning of the lens assembly and ensures correct alignment between the lens 140 and the bottom housing 110.

[0036] According to one embodiment of the utility model, Figure 1 and Figure 2 As shown, the mainboard 130 is connected to the bracket 120 by screws. Specifically, two through holes 131 are provided on the mainboard 130, and the two through holes 131 are respectively located at two opposite corners on the mainboard 130. Correspondingly, two screw holes 123 are provided on the bracket 120, and the screw holes 123 correspond to the through holes 131 one by one. The screws (not shown in the figure) connecting the mainboard 130 and the bracket 120 are threadedly connected with the screw holes 123 after passing through the through holes 131. By providing the through holes 131 at two opposite corners on the mainboard 130, it is helpful to achieve uniform distribution of the screw locking force and reduce local stress concentration. In addition, a plurality of positioning holes 132 can be provided on the mainboard 130, and a plurality of positioning columns 124 can be provided on the bracket 120. The position of the mainboard 130 on the bracket 120 can be accurately positioned by the cooperation of the positioning columns 124 and the positioning holes 132, thereby reducing the possibility of deformation of the mainboard 130 due to screw locking. Preferably, two positioning holes 132 and two positioning columns 124 may be provided respectively, wherein the two positioning holes 132 may be provided respectively at other two opposite corners of the main board 130 to more effectively protect the main board 130 .

[0037] According to one embodiment of the utility model, Figure 1 and Figure 2 As shown, a plurality of fixing columns 116 (for example, two) may be provided, and the plurality of fixing columns 116 are respectively provided on both sides of the first lens hole 114 to provide more stable support for the bracket 120. Preferably, a reinforcing rib 117 may be provided between the fixing column 116 and the side wall 112 of the bottom shell 110 to improve the supporting capacity of the fixing column 116 for the bracket 120 and ensure the stability of the installation of the bracket 120.

[0038] According to one embodiment of the utility model, Figure 2 As shown, a silicone ring 150 is provided in the first lens hole 114 , and the lens 140 extends into the silicone ring 150 , wherein the silicone ring 150 can prevent stray light in the bottom shell 110 from entering the lens 140 to affect the imaging effect, and can also play a role in physical protection of the lens 140 . Figure 3 A schematic diagram of a silicone ring 150 according to an embodiment of the present invention is shown. Figure 2 and Figure 3 As shown, a card slot 151 is provided on the outer circumference of the silicone ring 150, and the silicone ring 150 can be connected to the bottom shell 110 through the card slot 151. Such a configuration not only simplifies the installation process of the silicone ring 150, but also makes replacement more convenient and quick. Specifically, the user only needs to gently press the silicone ring 150 into the first lens hole 114 to achieve the connection between the silicone ring 150 and the bottom shell 110; when removing the silicone ring 150, there is no need to use complex tools, and the user can directly pull the silicone ring 150 out of the first lens hole 114 by hand.

[0039] Figure 4 A schematic diagram of a camera 200 according to an embodiment of the present utility model is shown. Figure 4 As shown, the camera 200 includes the lens fixing structure 100 as described above.

[0040] Compared with the prior art, the embodiment of the utility model provides a lens fixing structure 100 and a camera 200, wherein the lens 140 is fixed on the bracket 120 along with the mainboard 130, and by respectively providing a first positioning portion 115 and a second positioning portion 122 that cooperate with each other on the bottom shell 110 and the bracket 120, the bracket 120 is not easily tilted or deformed due to the locking of the screws, thereby ensuring the concentricity of the lens 140 and the first lens hole 114, and reducing the possibility of interference between the lens 140 and the bottom shell 110.
