Abstract

A clamping device for mounting a mobile terminal device to a hot shoe of an image photographing apparatus includes a quick release structure and a clamping assembly. The quick release structure includes a cold shoe fixing piece for connecting to a quick release interface of the hot shoe, and a first locking structure for selectively quickly locking the cold shoe fixing piece to the hot shoe, or quickly unlocking the cold shoe fixing piece from the hot shoe. The clamping assembly is configured to clamp the mobile terminal device, so that the mobile terminal device can be mounted, together with the quick release structure, to a quick release interface of the image photographing apparatus along with the clamping device. This facilitates quick and reliable mounting of the mobile terminal device to the image photographing apparatus, and quick removal of the mobile terminal device from the image photographing apparatus.

First claim

What is claimed is:

1 . A clamping mechanism for clamping a mobile terminal device, comprising:
a first clamping part and a second clamping part disposed opposite to the first clamping part, to enclose an accommodating space configured to accommodate a mobile terminal device; and a manual operation part, disposed outside the accommodating space and configured to drive the first clamping part and the second clamping part to move between a clamping position and a releasing position, wherein at the clamping position, the first clamping part and the second clamping part are capable of clamping the mobile terminal device, and at the releasing position, the first clamping part and the second clamping part are capable of releasing the mobile terminal device.

2 . The clamping mechanism according to claim 1 , wherein the manual operation part comprises at least one pressing protrusion configured to drive the first clamping part and the second clamping part to move from the clamping position to the releasing position; and
the at least one pressing protrusion is disposed on at least one of the first clamping part or the second clamping part.

3 . The clamping mechanism according to claim 2 , wherein the at least one pressing protrusion comprises
a pressing protrusion on the first clamping part; and a pressing protrusion on the second clamping part opposite to the pressing protrusion on the first clamping part.

4 . The clamping mechanism according to claim 3 , wherein the pressing protrusion on the first clamping part is located on a side of the first clamping part facing the second clamping part; and
the pressing protrusion on the second clamping part is located on a side of the second clamping part facing the first clamping part.

5 . The clamping mechanism according to claim 1 , further comprising:
an elastic reset member to reset the first clamping part and the second clamping part from the releasing position to the clamping position.

6 . The clamping mechanism according to claim 5 , wherein the elastic reset member is a tension spring; and
two ends of the tension spring are respectively fixed to the first clamping part and the second clamping part, or one of the two ends of the tension spring is mounted to a fixing position.

7 . The clamping mechanism according to claim 1 , wherein the first clamping part comprises a first engaging rack facing the second clamping part;
the second clamping part comprises a second engaging rack facing the first clamping part; and the first engaging rack is engaged with the second engaging rack to move the first clamping part and the second clamping part in opposite directions, under operation of the manual operation part, to clamp or release the mobile terminal device.

8 . The clamping mechanism according to claim 7 , further comprising: a transmissive gear,
wherein the first engaging rack are in transmissive connection with the second engaging rack via the transmissive gear.

9 . The clamping mechanism according to claim 1 , wherein at least one of an inner surface of the first clamping part for contacting the mobile terminal device, or an inner surface of the second clamping part for contacting the mobile terminal device comprises an elastic pad.

10 . The clamping mechanism according to claim 9 , wherein the elastic pad comprises at least one part to contact a side of the mobile terminal device, and a surface of the at least one part is a cambered surface.

11 . The clamping mechanism according to claim 1 , wherein a decorative piece is disposed on at least one of an outer surface of the first clamping part facing away from the mobile terminal device, or an outer surface of the second clamping part facing away from the mobile terminal device.

12 . The clamping mechanism according to claim 1 , further comprising:
a cover body, wherein the first clamping part and the second clamping part are slidably disposed on a first surface of the cover body.

13 . A clamping device for mounting a mobile terminal device to a hot shoe of an image photographing apparatus, comprising:
a quick release structure, comprising
a cold shoe fixing piece to connect to a quick release interface of the hot shoe, and
a first locking structure to selectively quickly lock the cold shoe fixing piece to the hot shoe, or quickly unlock the cold shoe fixing piece from the hot shoe; and
a clamping assembly fixed to the cold shoe fixing piece to selectively clamp or release a mobile terminal device.

14 . The clamping device according to claim 13 , wherein the first locking structure comprises:
a stud configured to fix to the clamping assembly on the cold shoe fixing piece; and a locking nut mounted on the stud.

15 . The clamping device according to claim 13 , further comprising a quick release seat and a handle connection base, wherein
the quick release seat is rotatably connected to the handle connection base, the quick release seat is in quick release connection with the cold shoe fixing piece, and the handle connection base is fixed to a handle of an image photographing apparatus.

16 . The clamping device according to claim 13 , wherein the clamping assembly comprises a clamping mechanism connected to the cold shoe fixing piece;
a clamping mechanism comprising:
a first clamping part,
a second clamping part disposed opposite to the first clamping part to enclose an accommodating space configured to accommodate a mobile terminal device, and
a manual operation part, disposed outside the accommodating space configured to drive the first clamping part and the second clamping part to move between a clamping position and a releasing position, wherein
at the clamping position, the first clamping part and the second clamping part are capable of clamping the mobile terminal device, and
at the releasing position, the first clamping part and the second clamping part are capable of releasing the mobile terminal device.

17 . The clamping device according to claim 16 , wherein the clamping mechanism is rotatable relative to the cold shoe fixing piece.

18 . The clamping device according to claim 17 , wherein the clamping mechanism is configured to selectively rotates the mobile terminal device to a horizontal position or a vertical position.

19 . The clamping device according to claim 16 , wherein the clamping assembly further comprises a support mechanism fixed to the cold shoe fixing piece; and
the clamping mechanism is configured to rotatably connected to the support mechanism.

20 . A photographing apparatus, comprising:
a camera; and a clamping device, wherein a cold shoe fixing piece of the clamping device is clamped on a hot shoe of the camera, the clamping device comprises:
a quick release structure, comprising the cold shoe fixing piece to connect to a quick release interface of the hot shoe, and a first locking structure to selectively quickly lock the cold shoe fixing piece to the hot shoe or quickly unlock the cold shoe fixing piece from the hot shoe, and
a clamping assembly fixed to the cold shoe fixing piece to selectively clamp or release a mobile terminal device.
