Abstract

The present disclosure provides a connecting bracket and a camera system. The camera system may include a first lens unit, a second lens unit, a first image sensor unit corresponding to the first lens unit, a second image sensor unit corresponding to the second lens unit, and a connecting bracket configured to connect the first lens unit and the first image sensor unit to form a first camera component, and connect the second lens unit and the second image sensor unit to form a second camera component. A predetermined angle may be formed between a first optical axis of the first camera component and a second optical axis of the second camera component.

First claim

the connecting bracket further includes:
a first mounting part on the first mounting surface configured to cooperate with the first connecting part to mount the first lens unit on the connecting bracket; and
a second mounting part on the third mounting surface configured to cooperate with the second connecting part to mount the second lens unit on the connecting bracket.

4. The camera system of claim 3 , wherein
the first connecting part includes a first threaded joint and the first mounting part includes a first threaded connector corresponding to the first threaded joint; or
the second connecting part includes a second threaded joint and the second mounting part includes a second threaded connector corresponding to the second threaded joint.

5. The camera system of claim 3 , wherein
the first connecting part includes a first fixing plate and the first mounting part includes a first fixing seat corresponding to the first fixing plate, the first fixing plate being connected to the first fixing seat by one or more screws; or
the second connecting part includes a second fixing plate and the second mounting part includes a second fixing seat corresponding to the second fixing plate, the second fixing plate being connected to the second fixing seat by one or more screws.

6. The camera system of claim 1 , wherein at least one image sensor unit of the first image sensor unit or the second image sensor unit includes a third fixing plate, and the at least one image sensor unit is connected to the connecting bracket by one or more screws through the third fixing plate.

7. The camera system of claim 1 , wherein the predetermined angle is less than or equal to 15°.

8. The camera system of claim 1 , wherein the connecting bracket further includes a first aperture configured to transmit one or more optical signals from the first lens unit to the first image sensor unit, and a second aperture configured to transmit one or more optical signals from the second lens unit to the second image sensor unit.

9. The camera system of claim 8 , wherein the connecting bracket further includes:
a first protruding part disposed around the first aperture, the first protruding part being configured to limit a position of the first lens unit, provide a dust-proof function, or block an interference light; or
a second protruding part disposed around the second aperture, the second protruding part being configured to limit a position of the second lens unit, provide a dust-proof function, or block an interference light.

10. The camera system of claim 1 , wherein the connecting bracket further includes one or more springs configured to adjust at least one of the second mounting surface, or the fourth mounting surface.

11. The camera system of claim 1 , wherein the connecting bracket further includes a reinforced structure configured to strengthen the connecting bracket.

12. The camera system of claim 1 , wherein the first lens unit includes a telephoto lens unit, and the second lens unit includes a wide-angle lens unit.

13. A connecting bracket, comprising:
