Description

Technical Field

[0001] The utility model relates to the field of camera waterproof shells, in particular to a multi-directional control device applied to camera waterproof shells. Background Art

[0002] The multi-selector of a digital camera is usually in the form of a circular pad or a group of buttons used as a navigation tool. The multi-selector allows the user to navigate the camera menu, move the focus, view the enlarged picture in playback mode, and also allows other functions to be implemented. The multi-selector usually includes five buttons for controlling the up, down, left, and right directions and a button in the center of the buttons (usually marked "OK" or "SET" to confirm the selection). When the user holds the camera, the multi-selector is usually ergonomically located within the reach of the user's right thumb.

[0003] When taking photos underwater, the waterproof housing is used to protect the camera from water while allowing the user to access important functions of the camera from outside the housing. In order to enable the waterproof housing to operate the camera's multi-selector, some people have installed an operating pad on the waterproof housing (such as CN104335115B), but this operating pad still has shortcomings. Specifically, the pad operates the camera by pressing, but when operating, it often requires a lot of force to trigger the button (especially when the user is wearing gloves, the operation is more difficult), which is inconvenient for consumers to operate; secondly, the direction button on the pad is too close to the central button, and the user is prone to accidentally touch other buttons underwater.

[0004] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

The roller of the transmission rod pushes the transmission slider to move and presses the pressure-bearing part of the trigger lever, so that the action section of the trigger lever rotates around the fulcrum, and the trigger part triggers the camera button.

[0010] As a preferred solution, the transmission rod is arranged in a horizontal direction, and the transmission slider is arranged in a vertical direction.

[0011] As a preferred solution, the transmission slider has a pushing inclined surface adapted to the roller; and the first rotating rod is provided with a reset torsion spring.

The first mounting block 21, the second mounting block 22, and the third mounting block 23 can be fixedly connected to the waterproof housing by connecting screws.

[0036] During operation, the first toggle knob 10 is rotated, and the first toggle knob 10 drives the first toggle block 14 to push the transmission rod 12 to move horizontally to the left, and the roller 121 of the transmission rod 12 pushes the transmission slider 13 to move downward and press the pressure-bearing part 112 of the trigger lever 11, so that the action section of the trigger lever 11 rotates downward around the fulcrum, and the trigger part 111 of the trigger lever 11 triggers the camera button.

[0037] Furthermore, in actual application, the multi-directional control device of the present application has 4 sets of direction key driving mechanisms, and the 4 first dial knobs 10 are arranged at four corners, so as to correspond to the direction keys of the four directions of the camera (up, down, left, and right). Preferably, the triggering directions of the 4 first dial knobs 10 are the same (all are triggered clockwise or counterclockwise), so that it is more in line with the user's operating habits. It should be added that: in actual application, in order to avoid each other, the specific shape structures of the transmission rod 12 and the trigger lever 11 driven by the 4 first dial knobs 10 are different, but the functions and implementation methods in the entire driving mechanism are roughly the same.
