The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0028] Please refer to Figures 1 to 7, the shielding cover structure of the embodiment of the present utility model includes a cover body 1 and a support body 2. Among them, the cover body 1 is fixed to the circuit board, and the support body 2 is welded to the cover body 1. The cover body 1 has a receiving space 101 for accommodating the electronic components on the circuit board, so as to avoid squeezing the electronic components. The cover body 1 also has a first surface 102 and a second surface 103 arranged opposite to each other, and the first surface 102 is used to enclose and form the receiving space 101. The support body 2 is used to fix the camera assembly, and the support body 2 includes a plate body portion 201 and a fixing portion 202. The plate body portion 201 is welded to the second surface 103, and there are multiple fixing portions 202. All the fixing portions 202 are respectively formed on the plate body portion 201, and all the fixing portions 202 extend away from the cover body 1 from the plate body portion 201. Moreover, all the fixing portions 202 and the plate body portion 201 jointly define an installation space 203, and the camera assembly is restricted within the installation space 203.

[0029] In the embodiment of the present utility model, the cover body 1 is fixed to the circuit board, and the support body 2 is welded to the cover body 1. The process is simple, the fixation is firm, and the space occupied by the circuit board is saved. Moreover, the support body 2 does not require electroplating with matte tin and cutting, and the process is simpler, effectively reducing the production cost. Moreover, the cover body 1 and the support body 2 can be packaged and SMTed at one time after being welded together. The cover body 1 and the support body 2 do not need to be packaged and SMTed separately, further simplifying the process and reducing the production cost. In addition, all the fixing portions 202 extend away from the cover body 1 from the plate body portion 201 and jointly define the installation space 203 with the plate body portion 201, and the camera assembly is restricted within the installation space 203, which is convenient for assembling the camera assembly and easy to use.

[0030] Exemplarily, the camera assembly is electrically connected to the circuit board. The camera assembly and the circuit board are prior arts and will not be elaborated here.

[0031] In some embodiments, after the camera assembly is installed on the support body 2, all the fixing portions 202 can be bent towards each other so that all the fixing portions 202 cooperate with the plate body portion 201 to fix the camera assembly within the installation space 203. In other embodiments, after the camera assembly is installed on the support body 2, the fixing portions 202 do not need to be bent, and all the fixing portions 202 can cooperate with each other to clamp the camera assembly and fix the camera assembly on the support body 2. In other embodiments, other methods can also be used to fix the camera assembly on the support body 2, which will not be elaborated here.

[0032] In some preferred embodiments, please refer to Figure 2 、 Figure 6 and Figure 7, a first ventilation hole 104 is formed in the cover body 1, and the first ventilation hole 104 penetrates through the first surface 102 and the second surface 103. That is to say, the first ventilation hole 104 can communicate the accommodation space 101 with the outside. Accordingly, please refer to Figure 1 and Figure 5 , a second ventilation hole 20111 is formed in the plate body portion 201, and the second ventilation hole 20111 penetrates through the plate body portion 201. Moreover, the second ventilation hole 20111 communicates with the first ventilation hole 104, so as to realize the communication between the accommodation space 101 and the outside. The provision of the first ventilation hole 104 and the second ventilation hole 20111 can not only promote the heat dissipation of the electronic device accommodated in the cover body 1. Moreover, after the cover body 1 is fixed to the circuit board, the circuit board will seal the opening of the accommodation space 101. If the accommodation space 101 is completely sealed, the air inside the accommodation space 101 will expand at high temperature, and there may be a risk of implosion. The first ventilation hole 104 and the second ventilation hole 20111 can effectively reduce the risk of implosion and further improve the fixing reliability.

[0033] As an example, when assembling the cover body 1 and the support body 2, the first ventilation hole 104 and the second ventilation hole 20111 can also be simultaneously penetrated by the positioning pins, so as to realize the pre-positioning of the support body 2 on the cover body 1, further improving the assembly accuracy and being more convenient for subsequent welding.

[0034] In some examples, two first ventilation holes 104 can be formed in the cover body 1. Accordingly, two second ventilation holes 20111 are also formed in the plate body portion 201, and the second ventilation holes 20111 and the first ventilation holes 104 are arranged in one-to-one correspondence, which not only further improves the heat dissipation performance, but also is more convenient for rapid and accurate pre-positioning.

[0035] As an alternative implementation manner, the above welding can be laser spot welding. It can be understood that in other implementations, other welding methods can also be used, which will not be elaborated here.

[0036] As an alternative implementation manner, the circuit board can be a PCB (Printed Circuit Board). It can be understood that in other implementations, the circuit board can also be other circuit boards, which will not be elaborated here.

[0037] In some preferred embodiments, a first insulating layer is formed on the first surface 102. The first insulating layer can provide electrical and mechanical protection, reduce the influence of electromagnetic radiation on the surrounding circuits, and improve the heat resistance and chemical resistance of the housing 1, thereby enhancing the reliability of the housing 1, enabling the housing 1 to better protect the electronic devices and extend their service life. As an example, the first insulating layer can be a paint layer coated on the first surface 102, which has good insulation effect and low cost. It can be understood that in other embodiments, the first insulating layer can be other insulating structures, which will not be elaborated here.

The welding regions 2012 have a fourth surface 20121, and the fourth surface 20121 is welded to the second surface 103 of the housing 1. The third surface 20112 and the fourth surface 20121 are located on both sides of the plate body portion 201 in the thickness direction. In this embodiment, the square region 2011 can be used to support the camera assembly, improving the assembly stability. The welding regions 2012 of the plate body portion 201 are welded to the housing 1, which can not only quickly and accurately identify the welding positions, but also no solder joints are arranged in the square region 2011, avoiding affecting the assembly of the camera assembly, thereby improving the assembly quality.

[0039] As an example, please refer to Figure 5 and Figure 6 , there are four welding regions 2012, and the four welding regions 2012 are respectively formed at the four corners of the square region 2011, so that the support 2 can be more stably and effectively fixed to the housing 1.

[0040] As an example, please refer to Figure 5 , two second ventilation holes 20111 are formed on the square region 2011, and the two second ventilation holes 20111 are arranged at both ends of a diagonal line close to the square region 2011, thereby further improving the heat dissipation performance.

It can be understood that in other embodiments, the second insulating layer can be other insulating structures, which will not be elaborated herein.

[0044] In some embodiments, a third insulating layer is formed on the fifth surface 2021. The third insulating layer can provide electrical and mechanical protection, improve the heat resistance and chemical resistance of the fixing portion 202, thereby improving the reliability of the fixing portion 202, enabling the fixing portion 202 to better limit the imaging component and extending its service life.

[0045] Exemplarily, the third insulating layer can be a paint layer coated on the fifth surface 2021 of the fixing portion 202, which has good insulation effect and low cost.

[0049] In some more preferred embodiments, please refer to Figure 5 , the square area 2011 has four sides, and fixing portions 202 are formed on at least three of the sides.

[0050] As an alternative embodiment, please refer to Figure 5 , fixing portions 202 are formed on three sides of the square area 2011, and no fixing portion 202 is provided on the other side, which is more convenient for wiring, thereby connecting the imaging component and the circuit board more stably.

[0051] In some examples, please refer to Figure 5, the four sides of the square area 2011 include two relatively arranged first sides 20113 and two relatively arranged second sides 20114. Fixing parts 202 are respectively formed on two first sides 20113 and one of the second sides 20114, and the number of fixing parts 202 arranged on the two first sides 20113 is equal, so that the support body 2 can more stably and effectively limit the imaging component.
