Problems solved by technology
However, due to the coaxiality requirements between the lens and the lens holder, the tolerance zone must be designed to be narrow enough, resulting in the defects that the total area of the contact gap is too small and the bonding strength is not enough, which cannot meet the user's requirements.
Especially after the cycle test of temperature shock and mechanical shock in the later stage, it is very common for the lens to fall off the lens mount, which leads to a great reduction in the yield of the lens module

Embodiment Construction
[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0021] see figure 1 and figure 2 , the lens barrel 100 of the first embodiment of the present invention is used to install the lens 200, the lens barrel 100 and the lens 200 are clearance fit, and the inner wall 11 of the lens barrel 100 is provided with a holding groove 20, so The lens 200 is bonded to the lens barrel 100 by filling the gap in the clearance fit and the adhesive 30 in the holding groove 20 .
[0022] For another way of describ...

The invention relates to the field of mobile terminals, particularly to a lens cone comprising a first end surface, a second end surface, and a receiving hole penetrating the first end surface and thesecond end surface. The receiving hole is used for receiving a lens; and a first clearance is formed between the inner wall of the receiving hole and the outer edge of the lens. A holding groove is formed in the first end surface; and the opening of the holding groove is communicated with the inner wall of the receiving hole. The lens is adhered to the lens cone by bonders filling the first clearance and the holding groove. Because of the holding groove, more bonders are received and thus the contact area between the lens cone and the bonders are increased, so that the lens is bonded firmly.In addition, the invention also relates to a lens module including the lens cone.
Description
technical field [0001] The invention relates to the field of mobile terminals, in particular to a lens barrel and a lens module including the lens barrel. Background technique [0002] In today's mobile terminal field, taking pictures and taking pictures has become an indispensable function. The component that realizes this function is usually a lens module. The lens module includes a lens, a lens mount, a motor, and a series of sensing elements. The lens mount is a key carrier for fixing the lens and assisting focusing. [0003] Most of the current lenses are fixed on the lens holder by straight cylinder or threaded installation method. For the straight cylinder lens, the corresponding lens holder also needs to be designed into a matching straight cylinder shape. After the assembly is completed, the lens and the Coating and fixing at the contact gap of the carrier. However, due to the coaxiality requirements between the lens and the lens holder, the tolerance zone must be...
