Description

Technical Field

[0001] This utility model relates to the field of gimbal technology. More specifically, this utility model relates to a quick-release structure, a stabilized gimbal, and a camera device. Background Technology

[0002] A gimbal stabilization head is a widely used support structure on cameras (camera phones, cameras, camcorders, etc.) to provide stable support for the camera. A gimbal stabilization head can output rotation in at least one direction to adjust the camera's angle and position. Currently, the connection between the camera and the gimbal stabilization head is either secured with multiple screws or uses a quick-release mechanism. While screw fixation provides good stability, the installation and removal of screws are cumbersome and time-consuming, resulting in low camera disassembly efficiency. Therefore, how to securely fix the camera to a gimbal stabilization head while simplifying the installation process is a technical problem that needs to be solved by those skilled in the art.

Detailed Implementation

[0048] The present invention will be further described in detail below with reference to the embodiments, so that those skilled in the art can implement it based on the description.

[0049] It should be noted that in the description of this utility model, the terms "horizontal", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0050] like Figures 1-6 As shown, an embodiment of this utility model provides a quick-release structure, including:

[0051] The connecting plate 1 has a first protrusion 2 and a second protrusion 3 on its outer side;

[0052] The fixing plate 4 has a receiving groove 5 in its middle part, and a first groove 6 and a second groove 7 are provided opposite to each other on the side wall of the receiving groove 5;

[0053] An elastic locking assembly is disposed in the second groove 7. When the connecting plate 1 is disposed in the fixing plate 4, the first protrusion 2 is embedded in the first groove 6. The locking 8 of the elastic locking assembly rotates into the receiving groove 5 and presses against the second protrusion 3.

[0054] In this embodiment, the elastic locking assembly unlocks, and under the action of external force, the locking buckle 8 of the elastic locking assembly rotates until it is completely housed in the second groove 7. At this time, the fixing plate 4 is placed into the receiving groove 5, and the bottom of the receiving groove 5 supports it. In the direction of the line connecting the first protrusion 2 and the second protrusion 3, the length of the receiving groove 5 is greater than the length of the connecting plate 1. At this time, the fixing plate 4 can be translated in the receiving groove 5, so that the first protrusion 2 is embedded in the first groove 6. At this time, the external force is removed, and the locking buckle 8 rotates until its pressing end moves into the receiving groove 5 and presses against the second protrusion 3. At this time, the connecting plate 1 can be fixed in the receiving groove 5, realizing the connection between the connecting plate 1 and the fixing plate 4. When it is necessary to remove the connecting plate 1 from the fixing plate 4, the external force drives the locking buckle 8 to rotate until its pressing end rotates to be housed in the second groove 7. At this time, the second protrusion 3 is no longer locked by the locking buckle 8, and the connecting plate 1 can be removed from the receiving groove 5.

[0055] As one specific implementation method, such as Figure 5 and Figure 6 As shown, both the second protrusion 3 and the pressing end of the latch 8 are set as slopes, which makes the locking effect of the latch 8 on the second protrusion 3 better without affecting the rotation of the latch 8.

[0056] Preferably, in another embodiment of the present invention, the receiving groove 5 is a through groove, and two supporting parts 9 are provided opposite to each other on its side wall, and the connecting plate 1 is provided with a recessed part corresponding to the supporting part 9.

[0057] In this embodiment, the receiving groove 5 is a through groove, and the connecting plate 1 is supported by two support parts 9, thereby reducing the height of the receiving groove 5 and the weight of the fixing plate 4.

[0058] As one specific implementation method, such as Figure 4 and Figure 5 As shown, both the support part 9 and the recessed part are designed as slopes.

[0059] Preferably, in another embodiment of the present invention, the elastic locking assembly includes:

[0060] A rotating shaft 10 is disposed within the second groove 7;

[0061] A rotating component 11 is rotatably sleeved on the rotating shaft 10 at one end. The side wall of the second groove 7 is provided with a first notch 12 corresponding to the rotating component 11, and the other end of the rotating component 11 passes through the first notch 12.

[0062] The latch 8 is rotatably sleeved on the rotating shaft 10. The latch 8 is provided with a second notch 13, and one end of the rotating member 11 is disposed in the second notch 13.

[0063] The first torsion spring is sleeved on the rotating shaft 10 and connected to the rotating component 11 and the fixed plate 4 respectively;

[0064] The second torsion spring is sleeved on the rotating shaft 10 and connected to the latch 8 and the fixing plate 4 respectively.

[0065] In this embodiment, such as Figure 3 and Figure 4 As shown, the fixing plate 4 includes a base plate 14 and a cover plate 15. A receiving groove 5, a first groove 6, and a second groove 7 are provided on the base plate 14. The cover plate 15 is then installed on the base plate 14, sealing the first groove 6 and the second groove 7. An opening corresponding to the receiving groove 5 is provided on the cover plate 15. The rotating component 11 and the latch 8 both rotate along the rotating shaft 10. The two ends of the latch 8 slide against the base plate 14 and the cover plate 15, respectively. The rotating component 11 is disposed in the second notch 13 of the latch 8, and its two ends slide against the latch 8 and the cover plate 15, respectively. Grooves are cut into the base plate 14 and the latch 8 to form a first mounting cavity 16 for installing a first torsion spring. Under the force of the first torsion spring, the latch 8 rotates until its pressing end rotates into the receiving groove 5. Slots are cut into the rotating member 11 and the cover plate 15 to form second mounting cavities 17 for mounting the second torsion spring. Under the force of the second torsion spring, the rotating member 11 rotates until it abuts against the inner wall of one side of the first notch 12, at which point the elastic locking assembly is in a locked state. During the rotation of the rotating member 11, it does not contact the inner wall of the second notch 13 and does not drive the locking buckle 8 to rotate. When the elastic locking assembly needs to be unlocked, under the action of external force, the rotating member 11 rotates around the pivot 10. When the rotating member 11 rotates until it abuts against the inner wall of the second notch 13, it will drive the locking buckle 8 to rotate, so that the locking buckle 8 is completely housed in the second groove 7, completing the unlocking of the elastic locking assembly. At this time, both the first and second torsion springs are compressed. After the external force is removed, the first and second torsion springs return to their original state, the rotating member 11 and the locking buckle 8 return to their original positions, and the elastic locking assembly returns to the locked state.
