Support structure and camera module provided with same

A support structure comprises a support body, wherein the support body comprises a first surface and a second surface which is arranged opposite to the first surface, a groove used for placement of an optical filter is formed in the first surface, the side wall of the groove is arranged obliquely relative to the bottom face of the groove, and the orthographic projection in the direction facing the bottom face of the groove is located outside the bottom face of the groove. Therefore, when the first surface of the support body and a shot drive component are attached in a flush mode through adhesive, due to the fact the side wall of the groove is oblique relative to the bottom face of the groove, according to the hydromechanics, the obliquely-arranged side wall of the groove can provide the guide function for the flow direction of the overflowing adhesive; meanwhile, due to the fact that the side wall of the groove is arranged obliquely, a gap is reserved between the first surface of the support body and the shot drive component to form a containing space, the overflowing part of the adhesive between the first surface and the shot drive component can flow to the containing space along the side wall of the groove and is prevented from overflowing to the surface of the optical filter placed in the groove, the optical filtering performance of the optical filter is ensured, and accordingly the imaging effect of a camera module is good.

The invention discloses a landfill liquid guide and drainage system. The landfill liquid guide and drainage system comprises a diversion blind groove and a guide and drainage device installed in the diversion blind groove. The guide and drainage device is composed of a floral tube and an outer wrapping layer. A plurality of filter holes are formed in the floral tube. A cushion layer is arranged on the outer surface of the floral tube and is distributed in the axis direction of the floral tube. Grooves are formed in the outer surface of the cushion layer. The filter holes are distributed in the circumferential direction of the floral tube in four sets. The circle center angle of the portion, corresponding to the area where each set of filter holes are located, of the floral tube is 45 degrees. The cushion layer is located on the area, not occupied by the filter holes, of the outer side of the floral tube, wherein the corresponding circle center angle is 45 degrees. The cushion layer is arranged between the floral tube and the wrapping layer, and therefore the space between the floral tube and the wrapping layer is enlarged, and the liquid guide and drainage efficiency between the floral tube and the wrapping layer is improved; the grooves are formed, the contact area between the cushion layer and the wrapping layer is narrowed, and by means of the design, harmful liquid infiltrating the contact area of the cushion layer and the wrapping layer can be smoothly collected and converged into the guide and drainage floral tube.
