Description

Technical Field

[0001] This utility model relates to the field of electronic equipment, and in particular to a shielding cover with a lens bracket and a lens module. Background Technology

[0002] In related technologies, the shielding cover and camera bracket are two independent structures that need to be packaged separately and fixed to the printed circuit board (PCB) using SMT (Surface Mount Technology). The camera bracket, made of stainless steel, requires initial stamping, matte tin plating, and then cutting to meet SMT requirements. However, PCB space is limited, and directly fixing the camera to the PCB would occupy considerable space. The applicant's utility model patent application (CN223080371U) discloses a new technical solution that cleverly combines the shielding cover and lens. It uses a separate lens bracket (described in this text) welded to the outer surface of the shielding cover, fixing the lens to the outer surface without occupying PCB space; it only requires a board-to-board connector for connection. However, this solution's lens bracket includes a full-length fixing beam welded to the shielding cover surface, increasing the beam's thickness, material utilization, and the amount of welding area.

Detailed Implementation

[0019] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0020] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0022] Please refer to Figures 1 to 3The present invention relates to a shielding cover with a lens holder, comprising a cover body 10 and a lens holder 20. The cover body 10 is fixed to a printed circuit board, and the lens holder 20 is soldered to the cover body 10. The cover body 10 has a shielding cavity 101 inside, which is used to accommodate electronic components on the printed circuit board to shield the signals of each component and prevent interference between the components and external signals. The cover body 10 also has a first surface 102 and a second surface 103 disposed opposite to each other. The first surface 102 is attached to the printed circuit board and surrounds the shielding cavity 101. The lens holder 20 is used to fix a lens (not shown), and includes a fixing beam 21 soldered to the second surface 103 of the cover body 10 and fixing pieces 22, 23 formed by bending upward from the inner edge of the fixing beam 21. All the fixing pieces 22, 23 are bent and extended from the fixing beam 21 in a direction away from the cover 10, and the fixing pieces 22, 23 and the fixing beam 21 together restrict the fixing space 24, within which the lens is restricted.

[0023] In this embodiment of the utility model, the cover 10 is fixed to the printed circuit board, and the lens bracket 20 is soldered to the cover 10. The process is simple, the fixation is reliable, and it saves space on the printed circuit board. Furthermore, the lens bracket 20 does not require electroplating or cutting, making the process even simpler and effectively reducing production costs. Moreover, the cover 10 and the lens bracket 20 can be soldered together and packaged and SMT completed in one go, eliminating the need for separate packaging and SMT of the cover 10 and the lens bracket 20, further simplifying the process and reducing production costs. In addition, all fixing pieces 22 and 23 extend from the fixing beam 21 in a direction away from the cover 10 and together with the fixing beam 21, they restrict the fixing space 24. The lens is confined within the fixing space 24, which facilitates lens assembly and makes it convenient to use.

[0024] The fixing beam 21 includes a transverse beam 211 extending in the transverse direction and a pair of longitudinal beams 212 extending vertically from both ends of the transverse beam 211. A second positioning hole 213 is formed vertically through the transverse beam 211. The fixing piece includes a first fixing piece 22 formed by bending upward from the inside of the transverse beam 211 and a second fixing piece 23 formed by bending upward from the inside of the pair of longitudinal beams 212. The first fixing piece 22 protrudes towards the fixing space 24 and forms a supporting protrusion 221 to reduce the fixing support surface. The second fixing piece 23 has a locking hole 231 at the bending point with the longitudinal beam 212, which is used for snap-fit ​​fixing with the lens assembly. The first fixing piece 22 and the pair of second fixing pieces 23 are arranged in a triangular shape, and the fixing space 24 is open directly opposite the first fixing piece 22.

[0025] The cover 10 includes a top wall 107, a side wall 104 extending downward from the periphery of the top wall 107, and a flange 106 folded outward from the side wall 104. The shielding cavity 101 is formed by the top wall 107, the side wall 104, and the printed circuit board. The first surface 102 is the plane where the flange 106 is located and is directly attached to the printed circuit board. The second surface 103 is the plane where the top wall 107 is located, but different areas of the top wall 107 can have different heights, that is, the second surface 103 is not a unique plane. For example, in this embodiment, the top wall 107 where the lens bracket 20 is fixed is higher than the horizontal plane of other areas. Of course, in other embodiments, the area where the lens bracket 20 is fixed can also be lower than the horizontal plane of other areas.

[0026] The bottom surface of the fixed space 24, i.e., the top cover 107, is fixed to the outer periphery by the first fixing piece 22 and the second fixing piece 23. The top cover 107 has a first positioning hole 105 at the position corresponding to the second positioning hole 213 of the crossbeam 211. Both the first positioning hole 105 and the second positioning hole 213 consist of a pair, and their function is to accurately position the lens bracket 20 on the top cover 107 during welding. The first positioning hole 105 and the second positioning hole 213 can also serve as ventilation and heat dissipation transmission holes.

[0027] This utility model also includes a lens module, which includes the aforementioned housing 10, a lens bracket 20 welded to the housing 10, a lens (not shown) fixed to the fixed space 24, and a board-to-board connector (not shown) connecting the lens and the printed circuit board. One end of the board-to-board connector is connected to the lens, and the other end is connected to the printed circuit board by passing a cable around the housing 10.

[0028] The lens is provided with a hook structure corresponding to the locking hole 231 on the lens bracket 20. The hook structure is locked into the locking hole 231 for fixation to enhance the force of fixing the lens in the fixed space 24.

[0029] In some embodiments, the upper outer side of the lens is also provided with several slots (not shown). After the lens is installed in the fixing space 24, all the fixing pieces 22, 23 can be bent in opposite directions so that all the fixing pieces 22, 23 can be inserted into the slots on the top of the lens to achieve positioning and fixing in various directions.

[0030] As an optional implementation, the welding described above can be laser spot welding. It is understood that other welding methods may also be used in other implementations, which will not be elaborated here.

[0031] As an alternative implementation, the printed circuit board can be a PCB (Printed Circuit Board). It is understood that in other implementations, the printed circuit board can also be other types of printed circuit boards, which will not be elaborated upon here.

[0032] In some preferred embodiments, an insulating layer is formed on the first surface 102. This insulating layer provides electrical and mechanical protection, reduces the impact of electromagnetic radiation on surrounding circuits, and improves the heat and chemical resistance of the enclosure 10, thereby enhancing the reliability of the enclosure 10 and enabling it to better protect electronic devices and extend their service life. As an example, the insulating layer can be a paint layer coated on the first surface 102, offering good insulation and low cost. It is understood that in other embodiments, the insulating layer can be other insulating structures, which will not be elaborated upon here.

[0033] As an example, a shield with a lens holder can be applied to mobile phones or other electronic devices.

[0034] This invention uses a lens bracket 20 welded and fixed to the top wall 107 of the cover 10, and bends the lens bracket 20 from the inside to form several fixing pieces 22, 23, directly using the top wall 107 as the bottom surface of the fixing space 24. Compared with the prior art, this reduces the thickness of the lens bracket 20 as the bottom wall of the fixing space 24, thus reducing the overall height of the product.

[0035] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The above embodiments only illustrate preferred implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
