It can be understood that the electronic device in the present application may include an electronic device having a camera structure, such as a mobile phone, a tablet computer, a notebook computer, and a wearable device, and specifically, the electronic device in the embodiment of the present application may be a mobile phone.

Referring to fig. 1 and 2, fig. 1 is a schematic structural diagram of a camera assembly 100 of an electronic device according to an embodiment of the present disclosure, and fig. 2 is a schematic structural diagram of a cross section along a-a direction in fig. 1, where the camera assembly 100 generally includes a lens body 10, a lens holder 20, and a bracket 30. It is understood that the camera assembly 100 may further include a circuit board 50, and the circuit board 50 is connected to the lens holder 20 and an external device of the electronic device, which may be a front shell, a rear shell or a middle frame of the electronic device.

Specifically, the lens body 10 is substantially mounted in a mounting space provided on the lens holder 20, the lens holder 20 is mounted in a mounting space provided on the bracket 30, and an end of the lens holder 20 away from the lens body 10 is connected to the circuit board 50.

Further, the lens holder 20 generally includes an inner side wall 21 connected end to end, the inner side wall 21 encloses a lens hole 25, and the lens hole 25 is used for installing the lens body 10. The lens body 10 may be generally a cylindrical structure, and the outer periphery of the lens body 10 is fixedly connected with the inner side wall 21 of the lens hole 25, that is, the outer periphery of the lens body 10 is fixedly connected with the inner side wall 21 of the lens holder 20, so as to fixedly connect the lens body 10 with the lens holder 20.

It is understood that in some embodiments of the present application, a groove may be formed on an inner side wall of the lens hole 25, and a protrusion may be formed on an outer periphery of the lens body 10, and the protrusion and the groove cooperate to fixedly connect the lens body 10 and the lens holder 20. Alternatively, threads may be formed on the inner sidewall of the lens hole 25 and the outer circumference of the lens body 10, respectively, to fix the lens body 10 and the lens holder 20 by the threaded connection.

Of course, in other embodiments, the lens body 10 may have other shape structures, such as a rectangular body structure, a conical body structure, and the like. The outer periphery of the lens body 10 and the inner side wall of the lens hole 25 may also be fixed in other manners, for example, the fixing manner of the lens body 10 and the lens holder 20 may be realized by adhesive fixation, snap fixation, and the like.
