In this embodiment, the camera assembly is applied to an aircraft as an example, and a detailed description is given.

The structure and implementation principle of the camera assembly and the aircraft of the present embodiment are described in detail below with specific embodiments. The following specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.

Fig. 1 is the structural schematic diagram of the camera module provided by the utility model. As shown in fig. 1, the camera assembly comprises a lens mount 20 and a lens assembly 40 mounted on the lens mount 20, wherein the lens assembly 40 comprises a lens barrel 10 and at least one lens enclosed in the lens barrel 10;

the lens holder 20 includes a connection member connected to the lens assembly for driving the lens assembly 40 to move a preset displacement in the optical axis direction of the lens when the temperature inside the lens holder 20 rises, the preset displacement being used to compensate for the amount of change in the focal length caused by the expansion of the lens.

In this embodiment, the connecting member may specifically be a connecting structure having expansion with heat and contraction with cold functions. The lens assembly can be driven to move for a preset displacement. The connector may or may not be connected to the lens assembly. Taking the example that the connecting piece drives the lens assembly to move upwards, when in connection, the connecting piece can be connected with one end of the lens assembly far away from the lens base and drive the lens assembly to move upwards from one end of the lens assembly far away from the lens base, and the connecting piece can also be connected with one end of the lens assembly close to the lens base and push the lens assembly to move upwards from one end of the lens assembly close to the lens base. The above description only schematically illustrates the implementation of the connection, and the embodiment is not particularly limited herein with respect to other connection relationships between the connection member and the lens assembly.

One possible implementation is shown in fig. 1, and as shown in fig. 1, the connecting member may be specifically a thermal expansion member 30, and the top end of the thermal expansion member 30 is connected to a lens assembly 40. The lens assembly 40 includes a lens of at least one lens. Among the materials constituting the lenses, at least one of the lenses is made of plastic, and the other lenses may be made of glass or the like.

In the specific implementation process, when the temperature rises, the thermal expansion member 30 thermally expands, the lens thermally expands, and at this time, the thermal expansion member 30 drives the lens assembly 40 to move along the optical axis direction of the lens by a preset displacement, so as to compensate the focal length variation caused by the expansion of the lens.

The following describes in detail the implementation principle of the present camera module with reference to fig. 2. Fig. 2 is the working principle schematic diagram of the camera assembly provided by the utility model. As shown in fig. 2, (one) represents the position of the focal plane when the lens assembly 40 is unheated. Specifically, when the lens assembly 40 is not heated, the optical path is shown by a solid line, and at this time, the normal focal plane is located at a position a1, which is the plane L where the image sensor chip is located. And (ii) represents the position of the focal plane when the lens assembly 40 is heated in the prior art. Specifically, when the lens assembly 40 is heated, the lens in the lens assembly 40 is thermally expanded, and in the view shown in fig. 2, after the lens is thermally expanded, the specific optical path is shown by a dotted line, and the focal plane is located at a position a2, that is, the focal plane is moved downward by a distance Y, and the focal plane does not fall on the image sensor chip. And (iii) represents the position of the focal plane when the lens assembly 40 is heated when a thermal expansion member is provided in the camera head assembly. Specifically, in the view shown in fig. 2, when the lens assembly 40 is heated, the lens thermally expands, which will cause the focal plane to move downward, but at the same time, the thermal expansion member thermally expands, after being heated and expanded, the length of the thermal expansion piece along the optical axis direction of the lens is extended, so as to drive the lens component to move towards the direction far away from the image sensor chip, i.e., the lens assembly is driven to move upward, in the embodiment, the expansion displacement of the thermal expansion member 30 along the optical axis direction is equal to the displacement of the lens along the focal plane of the optical axis direction, i.e., the focal plane moves down by a distance Y equal to the distance X that the lens assembly moves up, the resulting focal plane a2 falls on the plane L where the image sensor chip is located, therefore, the focal plane after temperature change is coincident with the focal plane before temperature change, namely, the focal plane always falls on the image sensor chip, and the imaging definition is further ensured. This embodiment makes the distance that the connecting piece upwards drove the removal of lens subassembly equal with the distance that focal plane moves down to guaranteed that the focal plane is located the plane that image sensor chip located all the time, made the camera subassembly can shoot clear image.

As will be understood by those skilled in the art, an object expands thermally by an elongation, which is the temperature difference x the length of the object x the rate of thermal expansion. The movement amount of the focal plane of the lens along with the temperature rise can be obtained through limited experiments, and therefore the corresponding relation between the movement amount of the focal plane and the temperature rise is obtained. The final experimental data show that the relationship between the focal plane movement amount and the temperature rise presents a linear relationship. Since the temperature difference is given by the environment, a material having the highest possible thermal expansion coefficient can be selected and the length of the thermal expansion member can be determined by the above formula. Optionally, according to the overall size of the camera head assembly, the length of the thermal expansion member is determined, then the thermal expansion rate is determined, and finally the material corresponding to the thermal expansion rate is selected. That is, the material of the thermal expansion member in this embodiment is plastic satisfying the predetermined thermal expansion coefficient. In the present embodiment, the material of the thermal expansion member and the thermal expansion coefficient of the thermal expansion member are not particularly limited as long as the amount of focal length change caused by the expansion of the lens can be compensated.
