Description

Technical Field

[0001] This application relates to the technical field of underwater photography equipment, and particularly relates to a bracket device. Background Art

[0002] When taking underwater photos, insufficient light can lead to abnormal exposure and poor image quality. Especially as the diving depth increases, the light will become darker and darker, resulting in difficult imaging. Therefore, underwater photographers usually carry special flashlights and go underwater to take pictures together with the photographic equipment. For example, two flashlights are locked and fixed on the left and right sides of a waterproof camera or a camera waterproof housing (the camera is sealed and installed therein) through a mechanical structure, and the camera controls the synchronous operation of the flashlights through electrical or optical signals. In addition, a floating arm is usually installed between the flashlight and the waterproof camera or the camera waterproof housing to increase buoyancy to offset the gravity of the entire photographic equipment in water, so that the overall force is close to zero, and it is convenient for the photographer to operate and control flexibly underwater.

[0003] Before going underwater to take pictures, the photographer needs to carefully adjust and test the positions and angles of the flashlights on the left and right sides and the size of the floating arm to see if they are appropriate, and finally lock and fix them. Completing the above operations on the shore is not difficult, but it will become very difficult in water due to the influence of water resistance and buoyancy. Underwater, when the shooting angle needs to be changed from horizontal shooting to vertical shooting, the underwater photographer must first rotate the camera waterproof housing counterclockwise by 90 degrees. At this time, the flashlights and the floating arm will synchronously rotate to two positions arranged vertically and horizontally. Then the photographer must adjust the upper and lower flashlights and the floating arm to the horizontal position one by one, and finally lock and fix them. Conversely, when changing from vertical shooting back to horizontal shooting, the camera waterproof housing must be rotated clockwise by 90 degrees, and at this time, the positions of the left and right flashlights and the floating arm need to be adjusted again. Therefore, the conversion between horizontal shooting and vertical shooting underwater is very cumbersome and time-consuming. Summary of the Invention

Therefore, the various sequences in the specification and the drawings are only for clearly describing a certain embodiment, and do not mean that they are the necessary sequences, unless it is otherwise stated that a certain sequence must be followed.

[0038] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the described objects, and do not have any sequential or technical meanings. And the "connection" and "coupling" mentioned in the present application, unless otherwise specified, both include direct and indirect connection (coupling).

[0039] This embodiment provides a bracket device.

[0040] Please refer to Figures 1-8 , the bracket device includes a first base body 100, a second base body 200, a guide rail assembly 300, and a locking device 400.

[0041] Please refer to Figures 1-5 , the first base body 100 is used to connect with an underwater photographic device, and the second base body 200 is used to connect with a photographic auxiliary device. The guide rail assembly 300 is disposed between the first base body 100 and the second base body 200. The first base body 100 and the second base body 200 are movably connected through the guide rail assembly 300. The first base body 100 can rotate along an arc on the second base body 200 to form a first preset angle and a second preset angle with the second base body 200. The locking device 400 can switch between a locked state and an unlocked state. The locking device 400 restricts the movement of the first base body 100 on the second base body 200 in the locked state and allows the movement of the first base body 100 on the second base body 200 in the unlocked state.

[0042] Before taking underwater photos, the underwater photography device can be connected to the first base 100, and the photography auxiliary device can be connected to the second base 200. When taking underwater photos, if it is necessary to switch the shooting angle of the underwater photography device between the landscape shooting state and the portrait shooting state, the photographer can first switch the locking device 400 to the unlocked state, then rotate the first base 100 along the arc movement path to form a desired first preset angle or second preset angle with the second base 200, and then switch the locking device 400 to the locked state, so that the switching and locking between the portrait shooting state and the landscape shooting state of the underwater photography device can be achieved quickly and conveniently.

[0043] Please refer to Figures 1-5 , it should be noted that the underwater photography device can include a waterproof camera, a camera waterproof housing, etc. That is to say, the first base 100 can be connected to the underwater camera or the camera waterproof housing, and the photography auxiliary device can include but is not limited to an underwater flash and a floating arm. Please refer to Figure 3 and Figure 5 , in the actual application scenario, the underwater flash and the floating arm can be respectively arranged on the opposite sides of the second base 200, and the underwater flash and the floating arm can be generally arranged in the horizontal direction. When the first base 100 and the second base 200 form a first preset angle, the underwater photography device can be configured in the landscape shooting state, and when the first base 100 and the second base 200 form a second preset angle, the underwater photography device can be configured in the portrait shooting state.

[0044] Specifically, the rotation angle of the first base 100 on the second base 200 can be 90°. For example, please refer to Figure 3 , Figure 3 shows a schematic diagram of the bracket device in the landscape shooting state. When it is necessary to switch to the portrait shooting state, the photographer can first switch the locking device 400 to the unlocked state, then rotate the first base 100 counterclockwise by 90°, and then switch the locking device 400 to the locked state, so as to achieve the switching of the underwater photography device from the landscape shooting state to the portrait shooting state. On the contrary, please refer to Figure 5 , Figure 5 shows a schematic diagram of the bracket device in the portrait shooting state. When it is necessary to switch to the landscape shooting state, the photographer can first switch the locking device 400 to the unlocked state, then rotate the first base 100 clockwise by 90°, and then switch the locking device 400 to the locked state, so as to achieve the switching of the underwater photography device from the portrait shooting state to the landscape shooting state.

[0045] Please refer to Figure 1 and 2, in one embodiment, the guide rail assembly 300 includes a guide rail 310 and a movable member 320. The guide rail 310 is connected to or integrally formed with one of the first seat body 100 and the second seat body 200, and the movable member 320 is connected to or integrally formed with the other of the first seat body 100 and the second seat body 200. At least a part of the guide rail 310 is arc-shaped, and the movable member 320 is movably connected to the guide rail 310. The movable member 320 can move on the guide rail 310 so that the first seat body 100 rotates along an arc on the second seat body 200 to form a first preset angle and a second preset angle with the second seat body 200.

[0046] The movable connection between the first seat body 100 and the second seat body 200 is realized through the cooperation of the guide rail 310 and the movable member 320. When using the bracket device, the angle switching of the first seat body 100 is realized by the sliding of the movable member 320 along the guide rail 310. Specifically, please refer to Figure 2 , in this embodiment, the guide rail 310 is integrally formed with the first seat body 100, and the movable member 320 is fixedly connected to the second seat body 200. In other embodiments, the guide rail 310 can also be an independent structural member, which is fixedly connected to the first seat body 100.

[0047] It should be noted that in this embodiment, the main parts of the first seat body 100, the second seat body 200 and the guide rail 310 are all set to be arc-shaped, which is beneficial to improving the consistency of the structure of the bracket device and reducing the volume of the bracket device. In other embodiments, based on actual needs, the shapes of the first seat body 100 and the second seat body 200 can also be set to be disc-shaped, semi-circular or other suitable shapes.

[0048] Please refer to Figure 1 and 2 , in one embodiment, a first limiting member 330 and a second limiting member 340 are provided on the guide rail 310, and the movable member 320 is movably arranged between the first limiting member 330 and the second limiting member 340. When the movable member 320 moves to abut against the first limiting member 330, the first seat body 100 and the second seat body 200 form a first preset included angle. When the movable member 320 moves to abut against the second limiting member 340, the first seat body 100 and the second seat body 200 form a second preset included angle.

[0049] On the one hand, since the moving stroke of the moving member 320 on the guide rail 310 can only be between the first limiting member 330 and the second limiting member 340, the rotation angle of the first base body 100 is limited by the first limiting member 330 and the second limiting member 340. At the same time, the first limiting member 330 and the second limiting member 340 can also prevent the moving member 320 from disengaging from the two ends of the track. On the other hand, the user only needs to rotate the first base body 100 so that the moving member 320 abuts against the first limiting member 330 or the second limiting member 340, which indicates that the first base body 100 has been rotated to form a first preset included angle or a second preset included angle with the second base body 200. That is to say, the first limiting member 330 and the second limiting member 340 also play a role in feedback to prompt that the rotation of the first base body 100 is in place. Specifically, buffer pads 350 can be arranged on the sides of the first limiting member 330 and the second limiting member 340 facing the moving member 320, and the buffer pads 350 can be made of silica gel or rubber materials.

[0050] Please refer to Figures 6-8 , in an embodiment, the locking device 400 includes an operating mechanism 410, a transmission mechanism 420, and a locking mechanism 430. The operating mechanism 410 is configured to be able to move between a first position and a second position. The locking mechanism 430 is movably arranged between the guide rail 310 and the moving member 320. The locking mechanism 430 can move to a locking position and an unlocking position. When the locking mechanism 430 is in the locking position, it prevents the moving member 320 from moving on the guide rail 310. When the locking mechanism 430 is in the unlocking position, it allows the moving member 320 to move on the guide rail 310. The transmission mechanism 420 is arranged between the operating mechanism 410 and the locking mechanism 430. The transmission mechanism 420 can drive the locking mechanism 430 to move based on the movement of the operating mechanism 410. When the operating mechanism 410 moves to the first position, it drives the locking mechanism 430 to move to the locking position through the transmission mechanism 420, so that the locking device 400 is switched to the locking state. When the operating mechanism 410 moves to the second position, it drives the locking mechanism 430 to move to the unlocking position through the transmission mechanism 420, so that the locking device 400 is switched to the unlocking state.

[0051] Please refer to Figures 6-8, when it is necessary to switch the locking device 400 to the locked state, the user can move the operating mechanism 410 to the first position. The movement of the operating mechanism 410 drives the movement of the transmission mechanism 420, thereby driving the locking mechanism 430 to move to the locked position through the transmission mechanism 420, and then preventing the moving member 320 from moving on the guide rail 310 to realize the switching of the locking device 400 to the locked state. When it is necessary to switch the locking device 400 to the unlocked state, the user can move the operating mechanism 410 to the second position, drive the movement of the transmission mechanism 420 through the operating mechanism 410, thereby driving the locking mechanism 430 to move to the unlocked position through the transmission mechanism 420, and then allowing the moving member 320 to move on the guide rail 310 to realize the switching of the locking device 400 to the unlocked state.

[0052] Specifically, the operating mechanism 410 can move between the first position and the second position by rotation, linear motion or other suitable motion modes. For example, please refer to Figure 6 and 7 , the operating mechanism 410 can be configured as a rotatable knob 411, which is installed on the second seat body 200 through a rotating shaft 412. The "first position" can be the position when the knob 411 is in a "fallen" state in Figure 6 , and the "second position" can be the position when the knob 411 is in an "erect" state in Figure 7 . Of course, in other embodiments, the operating mechanism 410 can also be configured as a push-button switch for linear motion, and the operating mechanism 410 can also be installed on the moving member 320. That is, the motion form and installation position of the operating mechanism 410 can be flexibly set according to actual needs.

[0053] Please refer to Figures 6-8 , in one embodiment, the locking mechanism 430 includes a locking bolt 431, the locking bolt 431 is movably connected to the moving member 320, and a first locking slot 432 and a second locking slot 433 are provided on the guide rail 310. When the first seat body 100 moves to a first preset angle with the second seat body 200, the locking bolt 431 is aligned with the first locking slot 432. When the first seat body 100 and the second seat body 200 form a second preset angle, the locking bolt 431 is aligned with the second locking slot 433. The operating mechanism 410 is rotationally connected to the first seat body 100 or the second seat body 200. When the operating mechanism 410 rotates to the first position, it drives the locking mechanism 430 to move to the locked position through the transmission mechanism 420, so that the locking bolt 431 is inserted into the first locking slot 432 or the second locking slot 433. When the operating mechanism 410 moves to the second position, it drives the locking mechanism 430 to move to the unlocked position through the transmission mechanism 420, so that the locking bolt 431 is disengaged from the first locking slot 432 or the second locking slot 433.

[0054] When the first body 100 moves to a first preset angle with respect to the second body 200, the locking pin 431 aligns with the first locking slot 432. At this time, if it is necessary to switch the locking device 400 to the locked state, the user can rotate the operating mechanism 410 to the first position, thereby driving the locking mechanism 430 to move to the locked position through the transmission mechanism 420, so that the locking pin 431 is inserted into the first locking slot 432, and further preventing the movable member 320 from moving on the guide rail 310 through the engagement between the locking pin 431 and the first locking slot 432. When the first body 100 moves to a second preset angle with respect to the second body 200, the locking pin 431 aligns with the second locking slot 433. At this time, if it is necessary to switch the locking device 400 to the locked state, the user can rotate the operating mechanism 410 to the first position, thereby driving the locking mechanism 430 to move to the locked position through the transmission mechanism 420, so that the locking pin 431 is inserted into the second locking slot 433, and further preventing the movable member 320 from moving on the guide rail 310 through the engagement between the locking pin 431 and the second locking slot 433. That is to say, the "locked position" of the locking mechanism 430 can be understood as the position when the locking pin 431 is inserted into the first locking slot 432 or the second locking slot 433. The "unlocked position" of the locking mechanism 430 can be understood as the position when the locking pin 431 disengages from the first locking slot 432 and the second locking slot 433.

[0055] Please refer to Figures 6-8 , in one embodiment, a first locking inclined surface 434 is provided on the locking pin 431, and a second locking inclined surface 435 is provided in both the first locking slot 432 and the second locking slot 433. The first locking inclined surface 434 is used to abut against the second locking inclined surface 435 in the first locking slot 432 or the second locking slot 433 in the locked state of the locking device 400.

[0056] On the one hand, through the abutment between the first locking inclined surface 434 and the second locking inclined surface 435, the stable engagement between the locking pin 431 and the first locking slot 432 or the second locking slot 433 is achieved. On the other hand, the cooperation between the first locking inclined surface 434 and the second locking inclined surface 435 plays a guiding role in the movement of the locking pin 431 inserted into the first locking slot 432 or the second locking slot 433.

[0057] Please refer to Figures 6-8, in one embodiment, the transmission mechanism 420 includes a transmission member 421, a first transmission roller 422, a second transmission roller 423, and a transmission lever 424. The transmission member 421 is movably disposed on the movable member 320. The first transmission roller 422 is rotatably connected to the transmission member 421, and the second transmission roller 423 is rotatably connected to the locking bolt 431. The middle of the transmission lever 424 is rotatably connected to the movable member 320, and the first transmission roller 422 and the second transmission roller 423 are respectively located at both ends of the transmission lever 424. When the operating mechanism 410 rotates to the first position, it drives the first transmission roller 422 to press one end of the transmission lever 424, so that the transmission lever 424 rotates, and then presses the second transmission roller 423 through the other end of the transmission lever 424, so that the second transmission roller 423 drives the locking bolt 431 to insert into the first locking slot 432 or the second locking slot 433.

[0058] When it is necessary to switch the locking device 400 to the locked state, the user can rotate the operating mechanism 410 to the first position, so that the transmission member 421 drives the first transmission roller 422 to move toward one end of the transmission lever 424 under the pressure of the operating mechanism 410, thereby driving the transmission lever 424 to rotate through the first transmission roller 422, and then pressing the second transmission roller 423 through the other end of the transmission lever 424, and driving the locking bolt 431 to insert into the first locking slot 432 or the second locking slot 433 through the second transmission roller 423.
