TECHNICAL FIELD

The present disclosure relates to the field of waterproof cases of cameras, and in particular, to a multi-directional control device applied to a waterproof case of a camera.

BACKGROUND

A multi-selector of a digital camera is usually in the form of a circular pad or a group of buttons, which is used as a navigation tool. The multi-selector allows a user to activate navigate a camera menu, move a focus, and browse enlarged images in a replay mode, and further allows other functions to be achieved. The multi-selector typically includes five buttons for controlling up, down, left, and right directions, and a button located in a center of a space enclosed by the buttons (usually marked as “OK” or “SET” to confirm selections). When a user holds the camera, the multi-selector is usually ergonomically located within reach of the right thumb of the user.

For underwater photography, a waterproof case is used to prevent water from entering the camera and allow a user to access important functions of the camera from the outside of the case. To enable the waterproof case to achieve operations of the multi-selector on the camera, a person has mounted an operation pad (such as CN104335115B) on the waterproof case. However, this operation pad still has shortcomings. Specifically, a user operates the camera through the pad by pressing, but buttons can be triggered only under great force during operation (especially when a user wears gloves, it is harder for the user to perform operations), leading to the problem of inconvenience of operation by consumers. Secondly, direction buttons on the pad are located too close to a center button, making it easy for a user to accidentally touch other buttons in water.

Therefore, it is necessary to research a new technical solution to solve the above problems.

Preferably, the transmission rod12is arranged in a horizontal direction, and the transmission sliding block13is arranged in an up-down direction. An upper end of the transmission sliding block13is provided with a pushing slope132that is adapted to the roller121. When the transmission rod12is pushed (moved), the roller121is in contact with the pushing slope132and drives the transmission sliding block13to move downwards through the pushing slope132. A lower end of the transmission sliding block13is provided with a pressing part131(the pressing part131is usually cylindrical).

Specifically, the multi-directional control device further includes a first mounting block21, a second mounting block22, and a third mounting block23. The first mounting block21, the second mounting block22, and the third mounting block23are arranged in sequence from right to left in this embodiment. The first mounting block21is provided with a first rotating shaft211arranged in a front-back direction. The trigger lever11is provided with a rotating hole adapted to the first rotating shaft211. The first rotating shaft211passes through the rotating hole, thus forming a fulcrum of the trigger lever11. The first mounting block21is further provided with a first mounting slot212that is adapted to the trigger lever11. A right section of the trigger lever11is located in the first mounting slot212. This not only plays a role in pre-positioning and facilitating mounting, but also has the advantage of improving the working stability.

The second mounting block22is provided with a guide slot that extends transversely towards the left and right. The transmission rod12is located in the guide slot in a manner of moving left and right, and the roller121is connected to a left end of the transmission rod12and is located outside the guide slot. The transmission sliding block13is located on a left side of the roller121. When the transmission rod12moves to the left side, the roller121pushes the transmission sliding block13to move downwards. The second mounting block22is further provided with a reset spring222configured to drive a push rod to be reset.

The third mounting block23is provided with a mounting hole231that penetrates through the third mounting block in the up-down direction, and the transmission sliding block13is mounted in the mounting hole231in a manner of moving up and down. Meanwhile, an elastic reset member configured to drive the transmission sliding block13to be reset is further arranged in the mounting block231, and the elastic reset member can be a spring sleeving the transmission sliding block. The third mounting block23is further provided with a second mounting slot232. A left section of the trigger lever11is located in the second mounting slot232. Preferably, the trigger part111of the trigger lever11is located on a left side of the third mounting block23, and the load-bearing part112is located on a right side of the second mounting slot232.

In practical applications, the first rotary rod101is sleeved with a reset torsion spring102and several limiting rings, thereby ensuring the working stability and rotation handfeel of the first rotary rod101. This is a conventional technique and will not be elaborated here. The first push block14is provided with a hook-shaped push part141, and the transmission rod12is provided with a force-bearing wall surface adapted to the push part141(the force-bearing wall surface is usually a straight wall surface). The first mounting block21, the second mounting block22, and the third mounting block23can be fixedly connected to the waterproof case through connecting screws.

During working, the first toggle knob10is turned. The first toggle knob10drives the first push block14to push the transmission rod12to move horizontally to the left; and the roller121of the transmission rod12pushes the transmission sliding block13to move downwards and press the load-bearing part112of the trigger lever11, so that the action section of the trigger lever11rotates downwards around the fulcrum and the trigger part111of the trigger lever11triggers a button of the camera.

Further, in practical applications, the multi-directional control device of the present disclosure is provided with four groups of direction button driving mechanisms, and the four first toggle knobs10are arranged at four corners, corresponding to direction buttons of four buttons of the camera (up, down, left, and right). Preferably, trigger directions of the four first toggle knobs10are the same (all the first toggle knobs are triggered clockwise or counterclockwise). In this way, it is more in line with an operation habit of a user. It should be added that in practical applications, for avoidance, specific shapes and structures of the transmission rods12and the trigger levers11which are driven by the four first toggle knobs10are different, but their functions and implementations in the entire driving mechanism are roughly the same. Correspondingly, the first mounting block21is provided with a corresponding number of first mounting slots212; the second mounting block22is provided with a corresponding number of guide slots; and the third mounting block23is provided with a corresponding number of second mounting slots232.

During use, the multi-directional control device further includes a middle button driving mechanism, which has roughly the same principle as the direction button driving mechanism mentioned above. Specifically, the middle button driving mechanism includes a second toggle knob31, a first transmission lever32, and a second transmission lever33; the second toggle knob31is connected to a second rotary rod311; the second rotary rod311is provided with a second push block34; the first transmission lever32is provided with a rotating hole; and the rotating hole passes through the foregoing first rotating shaft211to form a fulcrum of the first transmission lever32. The first mounting block21is provided with a second rotating shaft213, and the second transmission lever33has a rotating hole. The rotating hole of the second transmission lever33passes through the second rotating shaft213, thus forming a fulcrum of the second transmission lever33. The second push block34acts on one side (right side) of the fulcrum of the first transmission lever32, and the other side (left side) of the fulcrum of the first transmission lever32acts on the second transmission lever33. Specifically, in conjunction with the accompanying drawings, when the second toggle knob31is turned downwards, the second toggle knob31drives the second push block34to downwards press the first transmission lever32. A left section of the first transmission lever32upwarps, thereby acting on the second transmission lever33. A right section of the second transmission lever33rotates upwards around its fulcrum, and a left section of the second transmission lever33rotates downwards around its fulcrum, thereby triggering a middle button of the camera.

The design focus of the present disclosure is that compared with the prior art, the multi-directional control device applied to the waterproof case of the camera operates the camera in the waterproof case by toggling, instead of pressing directional buttons of the camera, so that the multi-directional control device is more labor-saving, is in line with operation habits of some persons, and brings different operation selections for consumption. Secondly, the specific design of the control device of the present disclosure also has the advantages of easy operation, reliability, and the like.
