Description

Technical Field

[0001] This utility model relates to the field of lens structure design technology, specifically to a structure and lens that allows the lens interface to be adjusted at an angle perpendicular to the lens optical axis. Background Technology

[0002] In existing designs, the lens and camera are connected via an interface. For example... Figure 1 In the lens shown, the interface 1' is fixed to the lens barrel 2' by screws, and then connected to the camera side by threads 3'. Therefore, after the threads 3' of the lens interface and the corresponding threads of the camera interface are tightened and installed in place, the relative axial angle between the lens and the camera is fixed and cannot be adjusted.

[0003] This fixed axial angle may cause positional interference between components on the lens side, such as the aperture housing 4' or the focusing motor 5', and structural components on the customer's camera side, such as the camera mount or bracket, thereby affecting the installation of structural components on the camera body side. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a structure and lens that enables the lens interface to be adjusted at an angle perpendicular to the optical axis of the lens, thereby achieving a vertical and stable connection between the lens and the camera, while allowing the angle to be arbitrarily adjusted in the direction perpendicular to the optical axis of the lens, thus avoiding the impact of lens-side components on the installation of main unit-side structural components.

[0005] In a first aspect, this utility model provides a structure for achieving adjustable angle of the lens interface perpendicular to the optical axis of the lens, comprising:

[0006] The retaining ring is used to fix the lens barrel in place.

[0007] An interface component, wherein the outer diameter of one end of the interface component is larger than the inner diameter of the fixing ring, is engaged between the fixing ring and the lens barrel, and can rotate within the accommodating space between the fixing ring and the lens barrel; the other end of the interface component is provided with a connecting structure that matches the connecting structure of the camera.

[0008] A wave-shaped washer is placed between one end of the interface component and the fixing ring. The height of the wave-shaped washer in its free state is greater than the gap between one end of the interface component and the fixing ring. The rebound force after the wave-shaped washer is compressed makes the interface component perpendicular to the optical axis of the lens.

[0009] Furthermore, the retaining ring is fixedly connected to the lens barrel by multiple screws.

[0010] Furthermore, the connection structure of the interface component is threaded.

[0011] Optionally, the ratio of the height of the waveform washer in its free state to the gap between one end of the interface and the retaining ring is 10:7.

[0012] Optionally, the ratio of the height of the waveform washer in its free state to the gap between one end of the interface piece and the retaining ring is 10:5.

[0013] Optionally, the wave washer is a metal wave washer.

[0014] Optionally, the waveform washer is a rubber waveform washer.

[0015] Secondly, this utility model provides a lens, including the structure described in the first aspect that enables the lens interface to be angled perpendicular to the optical axis of the lens.

[0016] The advantages of this utility model are:

[0017] By disassembling the original lens mount into an interface component and a retaining ring, the retaining ring is fixed to the lens barrel, and the interface component is secured between the retaining ring and the lens barrel. This allows the interface component to rotate within the space between the retaining ring and the lens barrel, thereby changing the angle of the lens relative to the optical axis of the camera. At the same time, a wave-shaped washer fills the gap between one end of the interface component and the retaining ring. The rebound force of the wave-shaped washer after compression ensures that the interface component is vertically fixed to the optical axis of the lens, allowing the lens angle to be arbitrarily adjusted in the vertical optical axis direction. This avoids the lens-side components affecting the installation of the main unit-side structural components. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0028] Please see Figures 3 to 5 As shown, this embodiment provides a structure 100 for making the angle of the lens interface perpendicular to the optical axis of the lens adjustable, including:

[0029] The retaining ring 1 is detachably and fixedly connected to the lens barrel 200;

[0030] Interface component 2, one end of which has an outer diameter larger than the inner diameter of the fixing ring 1, is engaged between the fixing ring 1 and the lens barrel 200, and can rotate within the accommodating space between the fixing ring 1 and the lens barrel 200; the other end of the interface component 2 is provided with a connecting structure 21, which matches the connecting structure of the camera.

[0031] A wave washer 3 is disposed between one end of the interface component 2 and the fixing ring 1. The height of the wave washer 3 in its free state is greater than the gap between one end of the interface component 2 and the fixing ring 1. The rebound force after the wave washer 3 is compressed makes the interface component 2 vertically fixed in the direction of the lens optical axis, so that when the lens 200 is connected to the host, it can rotate without loosening.

[0032] like Figure 5As shown, the wave-shaped washer 3 is typically composed of a series of interconnected wavy folds, a structure that allows it to deform under compression. When an external load is applied to the wave-shaped washer, the space between the folds shrinks, causing the entire washer to deform. During deformation, the material inside the wave-shaped washer 3 is subjected to tensile and compressive forces. When the external load disappears, the wave-shaped washer 3 returns to its original state through the elastic restoring force of its internal material. This restoring force is called the springback force. The springback force refers to the force generated when the wave-shaped washer 3 returns to its original state after being compressed and deformed. It is an important indicator of the elasticity of the wave-shaped washer 3. The greater the springback force, the better the recovery ability and the higher the elastic modulus of the wave-shaped washer.

[0033] Since the lens barrel 200 is not fixedly connected to the interface component 2, but the interface component 2 is vertically fixed to the optical axis of the lens by the axial rebound force of the wave washer 3, the interface component 2 or the lens barrel 200 can be rotated to change the relative axial angle between the lens and the camera, and the axial angle can be adjusted at any angle without restriction.

[0034] Specifically, the fixing ring 1 is fixedly connected to the lens barrel 200 by a plurality of screws 11.

[0035] Specifically, the connection structure 21 of the interface component 2 is threaded.

[0036] The wave washer 3 is a thin, circular fastener with a regular wave shape. The height of the wave washer 3 in its free state is selected according to the gap width between one end of the interface piece 2 and the fixing ring 1.

[0037] In one possible implementation, the ratio of the height of the waveform washer 3 in its free state to the gap between one end of the interface piece 2 and the retaining ring 1 is 10:7.

[0038] In another possible implementation, the ratio of the height of the waveform washer 3 in its free state to the gap between one end of the interface piece 2 and the retaining ring 1 is 10:5.

[0039] The wave-shaped washer 3 can be a metal wave-shaped washer or a rubber wave-shaped washer. The wave-shaped washer 3 can be made of different materials, such as metal or rubber. Different materials have different elastic moduli and ductility, thus affecting the rebound force. Generally, metal wave-shaped washers have higher rebound force, while rubber wave-shaped washers have lower rebound force.

[0040] Figure 6 This is a schematic diagram of the overall structure of a lens that uses the structure 100 in this embodiment to make the lens interface angle adjustable in the direction perpendicular to the lens optical axis.

[0041] The working principle of this utility model is as follows:

[0042] The interface component 2 is embedded into the end of the lens barrel 200 that connects to the camera. A wave-shaped washer 3 is then fitted, followed by a retaining ring 1. The retaining ring 1 is then tightened onto the lens barrel 200 using screws 11. Because the height of the wave-shaped washer 3 in its free state is greater than the gap between the interface component 2 and the retaining ring 1, the spring force after compression of the wave-shaped washer 3 allows the interface component 2 to be vertically fixed to the optical axis of the lens. Furthermore, since the lens barrel 200 is not fixedly connected to the interface component 2, after the threads of the interface component 2 are in place with the camera, the lens barrel 200 can be rotated according to the current position of the lens-side components to rotate them to the target position, thus avoiding any impact on the installation of the main unit-side structural components from the lens-side components.

[0043] This invention decomposes the original lens interface into an interface component and a retaining ring. The retaining ring is fixed to the lens barrel, and the interface component is held between the retaining ring and the lens barrel, allowing the interface component to rotate within the space between the retaining ring and the lens barrel, thereby changing the angle of the lens relative to the optical axis of the camera. At the same time, a wave-shaped washer fills the gap between one end of the interface component and the retaining ring, and the rebound force after the wave-shaped washer is compressed to fix the interface component perpendicular to the optical axis of the lens, making the angle of the lens arbitrarily adjustable in the perpendicular optical axis direction, and avoiding the impact of lens-side components on the installation of main unit-side structural components.

[0044] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
