[0002] Underwater photography can truly reflect underwater scenes, such as the life of aquatic plants and animals, geological data of the seabed and riverbed, archaeological discoveries, etc. Underwater photography is widely used in scientific research, military technology, sports, teaching, etc., and underwater photography has gradually entered people's lives with the development of technology.

[0003] During underwater photography, a photographic and video equipment is usually placed in a waterproof casing to resist deformation and damage caused by water pressure. Operating mechanisms such as buttons, knobs, and dials are provided on the outside of the waterproof casing of the photographic and video equipment. After being connected to the internal actuator through a sealed transmission shaft, the original buttons of the photographic and video equipment can be accessed. During underwater photography, since the cameraman wears a diving suit and gloves and other equipment, therefore, when taking pictures, it is more inclined to use larger-sized knobs or push rods to access some frequently used buttons.

[0004] With the rapid iteration of photographic and video equipment, the structure and size of professional photographic and video equipment are becoming more and more refined and compact. However, the existing actuator occupies a large space due to its complex structure and is difficult to meet the use requirements of a miniaturized waterproof casing. Summary of the Utility Model

[0039] The present application will be further described in detail below in conjunction with the accompanying drawings through specific embodiments. Similar elements in different embodiments are labeled with related similar element numbers. In the following embodiments, many detailed descriptions are provided to enable a better understanding of the present application. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification, which is to avoid overwhelming the core part of the present application with excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0040] In addition, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operation steps involved in each embodiment can also be reordered or adjusted in a manner obvious to those skilled in the art. Therefore, the specification and the drawings are only for clearly describing a certain embodiment, and do not mean to be the necessary composition and / or order.

[0041] The serial numbers assigned to the components in this document, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meaning. And the "connection" and "coupling" mentioned in the present application, unless otherwise specified, both include direct and indirect connection (coupling).

[0042] Underwater photography and imaging devices are usually installed in a waterproof housing, and operation components such as buttons, knobs, and dials are provided on the outside of the waterproof housing, and the original buttons of the photography and imaging device can be accessed through a sealed transmission structure connected to the internal actuator. Due to the fact that the cameraman needs to wear a diving suit and gloves, etc., the operating mechanism and the actuator tend to be products with larger sizes. Due to the continuous update and iteration of photography and imaging devices, the structural dimensions of professional photography and imaging devices are becoming more and more refined and compact. However, the existing actuator occupies a large space due to its complex structure, so it is difficult to meet the internal space requirements of the miniaturized waterproof housing corresponding to the miniaturized photography and imaging device.

[0043] To address the above problems, the present application proposes a two-way operating device for the waterproof housing of a photography and imaging device to streamline the structure and thus meet the usage requirements of the internal space of the miniaturized waterproof housing.

[0044] See Figures 1-3 As shown, the two-way operating device for the waterproof housing of the photography and imaging device provided in this embodiment includes: an operating mechanism 100 and an actuator 200.

[0045] The operating mechanism 100 includes a rotary operating member 10, a connecting shaft 11, and an elastic reset assembly 12. The connecting shaft 11 is rotatably disposed through the waterproof housing 1000. One end of the connecting shaft 11 is exposed outside the waterproof housing 1000, and the other end of the connecting shaft 11 extends into the waterproof housing 1000. The elastic reset assembly 12 is disposed inside the waterproof housing 1000 and connected to the connecting shaft 11. The rotary operating member 10 is fixed to one end of the connecting shaft 11 and is located outside the waterproof housing 1000 for the photographer to operate. The rotary operating member 10 can be rotated along the first operating direction F1 to drive the connecting shaft 11 to rotate from the initial position to the first preset rotation position around its axis, or can be rotated along the second operating direction F2 to drive the connecting shaft 11 to rotate from the initial position to the second preset rotation position around its axis. The elastic reset assembly 12 is used to rotate the connecting shaft 11 from the first preset rotation position or the second preset rotation position to the initial position.

[0046] In this embodiment, as Figure 1 shown, the first operating direction F1 and the second operating direction F2 are opposite rotation directions, that is, it can be made that after operating the rotary operating member 10, it can be rotated along the first operating direction F1 to drive the connecting shaft 11 to rotate from the initial position to the first preset position around its axis and the second preset position to which the connecting shaft 11 is rotated from the initial position by rotating along the second operating direction F2 are different positions. Under the action of the elastic reset assembly 12, when the connecting shaft 11 rotates to the first preset rotation position, it can be reset to the initial position, and when the connecting shaft 11 rotates to the second preset rotation position, it can also be reset to the initial position. In other words, for different preset rotation positions, the connecting shaft needs to be reset to the initial position under the action of the elastic reset assembly 12, and two-way operation can be realized by rotating the rotary operating member 10 along different operating directions.

[0047] In an embodiment of the present application, the elastic reset assembly 12 includes an elastic member 121 and a mounting seat body 122. Among them, the elastic member 121 is preferably a torsion spring. The elastic member 121 is sleeved on the connecting shaft 11. The mounting seat body 122 is fixed inside the waterproof housing 1000 and positions the torsion spring on the mounting seat body 122. That is, during the rotation of the connecting shaft 11 from the initial position to the first preset rotation position or the second preset rotation position, the torsion spring can store elastic potential energy, so that after releasing the rotary operating member 10, the connecting shaft 11 can be reset from the first preset rotation position or the second preset rotation position to the initial position under the action of the released elastic potential energy of the torsion spring.

[0048] To facilitate the photographer to operate the rotary operating member 10, two operating portions 101 are further provided on the rotary operating member 10. The two operating portions 101 are disposed on opposite sides of the rotary operating member 10 for the photographer to hold with the hand.

[0049] The actuator 200 includes a connection component 20, a first pressing part 21, and a second pressing part 22. Inside the waterproof housing 1000, there is a photographic and video recording device 2000 which has a first button 2001 and a second button 2002. The actuator 200 is arranged inside the waterproof housing 100, and the connection component 20 is connected to the other end of the connection shaft 11. Both the first pressing part 21 and the second pressing part 22 are connected to the connection component 20 and face or are directly opposite to the first button 2001 and the second button 2002 of the photographic and video recording device 2000 respectively.

[0050] The connection shaft 11 rotates to a first preset rotation position to drive the first pressing part 21 to press the first button 2001 through the connection component 20, and to make the second pressing part 22 disengage from or move away from the second button 2002, so that only the first pressing part 21 presses the first button 2001 to execute the function of the first button 2001.

[0051] The connection shaft 11 rotates to a second preset rotation position to drive the second pressing part 22 to press the second button 2002 through the connection component 20, and to make the first pressing part 21 disengage from or move away from the first button 2001, so that only the second pressing part 22 presses the second button 2002 to execute the function of the second button 2002.

[0052] It can be understood that both the first preset rotation position and the second preset rotation position are positions after the connection shaft 11 rotates a certain angle around its axis, and the connection shaft 11 only has axial rotation. In this embodiment, it can be considered that the angles of rotation of the connection shaft 11 around its axis at the first preset rotation position and the second preset rotation position are the same or different, which are specifically determined according to the distance between the first pressing part 21 and the first button 2001 and the distance between the second pressing part 22 and the second button 2002.

[0053] In this application, through the connection of the connection shaft 11, the rotation operation of the rotating operating member 10 by the photographer in the first operation direction F1 or the second operation direction F2 can be transmitted to the connection component 20 through the connection shaft 11. Furthermore, when the connection shaft 11 rotates to the first preset rotation position, the first pressing part 21 presses the first button 2001, and when the connection shaft 11 rotates to the second preset rotation position, the second pressing part 22 presses the second button 2002. By adopting the transmission mode of the connection shaft 11 to the connection component 20, the structure of this device can be effectively simplified to adapt to the use of the miniaturized waterproof housing 1000 corresponding to the miniaturized photographic and video recording device 2000.

[0054] In this embodiment, the operating mechanism 100 further includes a bushing 13. The bushing 13 is sealed and installed in the waterproof housing 1000. The connection shaft 11 is rotatably disposed in the bushing 13 and is fixedly connected to the rotating operating member 10.

[0055] In a specific embodiment, the rotation operating member 10 is rotatably connected to the bushing 13 by screws 131, and the appearance cover 132 is snap-fitted on the rotation operating member 10 to prevent the screws 131 from being exposed, so as to maintain the aesthetics of the product.

[0056] In one embodiment, a sealing ring 110 is also sleeved on the connecting shaft 11 to seal the gap between the connecting shaft and the bushing 13.

[0057] In the first embodiment of the present application, as Figure 1 and Figure 2 shown, the connecting assembly 20 includes a connecting member 201. The connecting member 201 has a first connecting portion 202 and a second connecting portion 203. The connecting member 201 is fixedly connected to the other end of the connecting shaft 11. Specifically, an internal thread hole 111 is provided at the other end of the connecting shaft 11, and a through hole 2011 is provided on the connecting member 201. The connecting member 201 can be fixedly connected to the other end of the connecting shaft 11 by passing a connecting bolt 204 through the through hole 2011 and screwing it into the internal thread hole 111.

[0058] In this embodiment, the first pressing portion 21 is perpendicular to the first connecting portion 202, and the second pressing portion 22 is perpendicular to the second connecting portion 203. The connecting member 201, the first connecting portion 202, and the second connecting portion 203 form a structure approximately in the shape of a Y, such that the first connecting portion 202 and the second connecting portion 203 are parallel to each other, and both the first connecting portion 202 and the second connecting portion 203 are arranged along the axial direction of the connecting shaft 11. In other words, both the first pressing portion 21 and the second pressing portion 22 are perpendicular to the axis of the connecting shaft 11.

[0059] When the photographer operates the rotary operating member 10 to rotate in the first operating direction F1, the connecting shaft 11 is driven to rotate synchronously about its axis, so as to rotate from the initial position to the first preset rotation position. During the rotation of the connecting shaft 11, the connecting member 201 can be driven to rotate synchronously, so that the first pressing portion 21 on the first connecting portion 202 moves in the direction towards the first button 2001, and the first button 2001 can be pressed by the first pressing portion 21. At the same time, the second pressing portion 22 on the second connecting portion 203 moves in the direction away from the second button 2002. After that, under the action of the elastic reset assembly 12, the connecting shaft 11 is reset from the first preset rotation position to the initial position. The photographer operates the rotary operating member 10 again at the initial position state to rotate in the second operating direction F2, drives the connecting shaft 11 to rotate synchronously about its axis, so as to rotate from the initial position to the second preset rotation position. During the rotation of the connecting shaft 11, the connecting member 201 is driven to rotate synchronously, so that the second pressing portion 22 on the second connecting portion 203 moves in the direction towards the second button 2002, and the second button 2002 can be pressed by the second pressing portion 22. At the same time, the first pressing portion 21 on the first connecting portion 202 moves in the direction away from the first button 2001, so as to operate different buttons.

[0060] See Figures 4-8 As shown, each figure shows a second embodiment of the connecting assembly 20 in the two-way operating device of the waterproof housing of the photographic and video device provided in the present application. In the second embodiment of the present application, only the structure of the connecting assembly 20 is different from that in the first embodiment. The connecting assembly 20 includes a linear movement conversion module 230, a first abutting portion 231, a second abutting portion 232 and a seat body 233. The input end of the linear movement conversion module 230 is connected to the other end of the connecting shaft 11. The first abutting portion 231 and the second abutting portion 232 are both installed at the output end of the linear movement conversion module 230. The linear movement conversion module 230 can convert the rotational movement of the connecting shaft 11 rotating to the first preset rotation position into a linear movement moving to the first preset movement position along its length direction. Or, the linear movement conversion module 230 can convert the rotational movement of the connecting shaft 11 rotating to the second preset rotation position into a linear movement moving to the second preset movement position along its length direction. The seat body 233 is fixed inside the waterproof housing 1000. The first pressing portion 21 and the second pressing portion 22 are arranged on the seat body 233 so as to be reciprocally slidable and resettable.

[0061] In this embodiment, the direction of the linear movement of the first preset movement position and the second preset movement position is the length direction of the linear movement conversion module 230.

[0062] As Figure 7As shown, at the first preset moving position, the first abutting portion 231 abuts against the first pressing portion 21 to press the first button 2001, while the second abutting portion 232 does not contact the second pressing portion 22. Thus, only the first button 2001 can be pressed through the first pressing portion 21. As Figure 8 shown, at the second preset moving position, the second abutting portion 232 abuts against the second pressing portion 22 to press the second button 2002, while the first abutting portion 231 does not contact the first pressing portion 21. Thus, only the second button 2002 can be pressed through the second pressing portion 22.

[0063] In this embodiment, the linear movement conversion module 230 includes a gear 2301 and a rack 2302. The gear 2301 is installed at the other end of the connecting shaft 11 and can rotate synchronously with the connecting shaft 11. In a specific embodiment, the connecting shaft 11 is coaxially connected to the gear 2301. The rack 2302 is slidably disposed inside the waterproof housing 1000, and the rack 2302 meshes with the gear 2301. Both the first abutting portion 231 and the second abutting portion 232 are installed on the rack 2302. When the connecting shaft 11 rotates to the first preset rotation position, the gear 2301 drives the rack 2302 to move along its length direction to the first preset moving position, that is, the rack 2302 converts the rotational movement of the gear 2301 into a linear movement along its length direction. The displacement amount of moving to the first preset moving position is related to the rotation angle of the connecting shaft 11 rotating from the initial position to the first preset rotation position. When the connecting shaft 11 rotates to the second preset rotation position, the gear 2301 drives the rack 2302 to move along its length direction to the second preset moving position, that is, the rack 2302 converts the rotational movement of the gear 2301 into a linear movement along its length direction. The displacement amount of moving to the second preset moving position is related to the rotation angle of the connecting shaft 11 rotating from the initial position to the second preset rotation position.

[0064] It can be understood that the first preset moving position and the second preset moving position are linear movements along the length direction of the rack 2302.

[0065] See Figures 9-12 shown. In the third embodiment of the present application, the difference between this embodiment and the second embodiment is that an extension connection unit 24 is further provided in the linear movement conversion module 230 of the present application to increase the transmission distance and achieve remote control.

[0072] When the photographer operates the rotation operating member 10 to rotate, and synchronously drives the connection shaft 11 to rotate from the initial position to the first preset rotation position. During this process, the first swing member 245 swings synchronously with the connection shaft 11. Under the action of the sliding portion 2461 sliding in the chute 2451, it can drive the second swing member 246 to swing. Under the action of the fork portion 2471 and the fork 2462, it drives the third swing member 247 to swing. The swinging third swing member 247 can drive the second extension shaft 248 to rotate around its axis, so as to drive the rack 2302 to move linearly to the first preset movement position through the gear 2301, and then press the first button 2001 by the way of the first abutting portion 231 abutting against the first pressing portion 21. When the photographer operates the rotation operating member 10 to rotate, and synchronously drives the connection shaft 11 to rotate from the initial position to the second preset rotation position. During this process, the first swing member 245 swings synchronously with the connection shaft 11. Under the action of the sliding portion 2461 sliding in the chute 2451, it can drive the second swing member 246 to swing. Under the action of the fork portion 2471 and the fork 2462, it drives the third swing member 247 to swing. The swinging third swing member 247 can drive the second extension shaft 248 to rotate around its axis, so as to drive the rack 2302 to move linearly to the second preset movement position through the gear 2301, and then press the second button 2002 by the way of the second abutting portion 232 abutting against the second pressing portion 22.

[0073] See Figure 14 As shown in the figure, the extended connection unit 24 provided by the fourth embodiment of the present application can be installed inside the waterproof housing 1000. See Figure 15As shown, the first swing member 245 and the second swing member 246 can be installed inside the waterproof housing 1000, while the third swing member 247 and the second extension shaft 248 are installed on the camera tray 1001. After assembling the camera tray 1001 into the inside of the waterproof housing 1000, the fork portion 2471 of the third swing member 247 can be inserted into the fork 2462 of the second swing member 246.

[0074] See Figures 6-8 As shown, in the above four embodiments, the connection assembly 20 further includes a first inclined surface contact portion 205, a second inclined surface contact portion 206, a first button reset member 207, and a second button reset member 208. The seat body 233 has a first installation channel (not shown in the figure) and a second installation channel (not shown in the figure).

The first inclined surface 2052 of the first inclined surface contact portion 205 faces the first abutting portion 231, and the second inclined surface 2062 of the second inclined surface contact portion 206 faces the second abutting portion 232.

[0075] When the connecting shaft 11 rotates to the first preset rotation position to drive the rack 2302 to move linearly to the first preset movement position through the gear 2301, the first abutting portion 231 contacts the first inclined surface 2052 of the first inclined surface contact portion 205 and presses the first button 21 by the first pressing portion 231.

[0076] When the connecting shaft 11 rotates to the second preset rotation position to drive the rack 2302 to move linearly to the second preset movement position through the gear 2301, the second abutting portion 232 contacts the second inclined surface 2062 of the second inclined surface contact portion 206 and presses the second button 22 by the second pressing portion 232.

[0077] In the present application, the first abutting portion 231 and the second abutting portion 232 are rotatably installed on the rack 2302 so as to contact the first inclined surface 2052 of the first inclined surface contact portion 205 and the second inclined surface 2062 of the second inclined surface contact portion 206 by rolling respectively.

[0078] In summary, for the two-way operating device of the waterproof housing of the photographic and video equipment provided in this application, through the connection of the connecting shaft, the rotation operation of the photographer along the first operation direction or the second operation direction can be transmitted to the connecting component through the connecting shaft. Furthermore, when the connecting shaft rotates to the first preset rotation position, the first pressing portion presses the first button, and when the connecting shaft rotates to the second preset rotation position, the second pressing portion presses the second button. By adopting the method of transmitting the connecting component through the connecting shaft, the structure of the device can be effectively simplified to adapt to the use of the miniaturized waterproof housing corresponding to the miniaturized photographic and video equipment.
