Specifically, the camera device 2 includes a CMOS sensor 21 and a lens 22, the sighting device 3 is a laser light, and the lighting device 4 is a fill light. Here, "the bracket 1 is configured to be directly fixed in the housing 9" means that the bracket 1 is a fixed structure of the code scanning module fixed on an external structure.

[0024] By means of the above technical scheme, the camera device 2, the aiming device 3 and the lighting device 4 do not need to be integrated on a PCB and then connected to the main board 8 in the shell 9 through the PCB, but are directly connected to the main board 8 through connection structures such as flexible circuit boards and welding wires. Moreover, the code scanning module of the present invention also has no shell structure, thereby reducing the size and cost of the code scanning module, which is beneficial to cost reduction and miniaturization of the data acquisition terminal.

[0025] In some embodiments, the code scanning module further includes a flexible circuit board 5, and the camera device 2 and the lighting device 4 are connected to the main board 8 via the flexible circuit board 5. Of course, the camera device 2 and the lighting device 4 are not limited to being connected to the main board 8 via the flexible circuit board 5.

[0026] In some embodiments, the aiming device 3 is connected to the mainboard 8 via welding wires 6 , but the present invention is not limited thereto.

[0027] In some embodiments, the bracket 1 is a single body structure, that is, the bracket 1 is formed in one step.

[0028] As a specific embodiment, the bracket 1 includes an aiming device fixing portion 11, a camera device fixing portion 12 and an illumination device fixing portion 13 arranged in sequence along the left and right directions. The aiming device fixing portion 11 is formed with a fixing groove 110 adapted to the aiming device 3, and the fixing groove 110 is open upward and extends and penetrates in the front-to-back direction. The camera device fixing portion 12 is formed with an installation groove 120 adapted to the camera device 2, and the installation groove 120 penetrates forward and opens upward, and the rear end of the installation groove 120 is formed with a first rear baffle 12 1, one end of the first rear baffle 121 is connected to the middle of one side of the aiming device fixing part 11, the camera device 2 is installed in the installation groove 120 and attached to the first rear baffle 121, the lighting device fixing part 13 is formed with an installation space 130 adapted to the lighting device 4, the installation space 130 is open forward and upward, and the rear end of the installation space 130 is formed with a second rear baffle 131, the second rear baffle 131 is located on the front side of the first rear baffle 121, and the lighting device 4 is installed in the installation space 130 and attached to the second rear baffle 131. Through this design, it is not only conducive to the reliable and reasonable installation of the camera device 2, the aiming device 3 and the lighting device 4, but also conducive to the miniaturization of the overall structure. Specifically, in order to achieve stable fixation, the aiming device 3 and the bottom wall of the fixing groove 110, the camera device 2 and the first rear baffle 121, and the lighting device 4 and the second rear baffle 131 can be fixed by adhesive.

[0029] Preferably, the second rear baffle 131 and the first rear baffle 121 are connected as one body through the connecting wall 320 , so as to enhance the overall structure. In a specific example, the portion of the flexible circuit board 5 between the camera device 2 and the lighting device 4 is arranged along the front side of the connecting wall 320 .

[0030] More preferably, the bracket 1 further comprises a first fixing plate 14 and a second fixing plate 15, wherein the first fixing plate 14 is connected to the rear bottom of the second rear baffle wall 131 and the connecting wall 320, and the first fixing plate 14 is formed with a first through hole 140 for screws to pass through, and the second fixing plate 15 is connected to the front of the aiming device fixing part 11 on the side opposite to the first rear baffle wall 121, and the second fixing plate 15 is formed with a second through hole 150 for screws to pass through.
