Description

Technical Field

[0001] The present application relates to the technical field of camera equipment, and more specifically to a dial device for a camera waterproof housing and a camera waterproof housing. Background Art

[0002] As people's desire to explore the underwater world increases, underwater photography has gradually become a popular leisure activity. When taking underwater photos, the camera is installed in a waterproof housing, which is usually made of high-strength, corrosion-resistant plastic materials or aluminum alloys, and uses a sealing rubber ring to prevent seawater from penetrating, protecting the camera, lens and other electronic equipment.

[0003] The camera is provided with several rotatable operating dials for accessing commonly used functions. For example, the aperture size or sensitivity can be quickly set by rotating the front operating dial, and the shutter speed can be quickly set by rotating the rear operating dial. Therefore, a corresponding dial device is also provided on the waterproof housing of the camera to realize the above functions of the camera from the outside or underwater.

[0004] Since a pair of handles are usually provided on both sides of the camera's waterproof housing to facilitate the photographer to grasp and operate the device, the existing technical solution is generally to set a dial operating mechanism on both sides or near the sides of the camera's waterproof housing, and transmit power inward through a sealed transmission shaft to drive the dial installed inside the waterproof housing and the camera operating panel to produce synchronous movement through friction or engagement. The contact state or pre-pressure amount of the above-mentioned dial and operating panel determines the operability and comfort. When the contact amount or pre-pressure amount is insufficient, the dial and the operating panel will slip; on the contrary, when the contact amount or pre-pressure amount is too large, the external dial operating mechanism feels heavy and has poor comfort, and in serious cases, it may even damage the camera operating panel.

[0032] The present application is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. 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, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and 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.

[0033] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations, and the operation steps involved in each embodiment can also be replaced or adjusted in a sequence in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing a certain embodiment and do not mean that the composition and / or sequence are necessary.

[0034] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0035] See also Figures 1 to 7The present application provides a dial device 1 (hereinafter referred to as "dial device") for a waterproof housing 2 of a camera 3, comprising an operating knob 11, a transmission mechanism 12, a dial 13 and a pre-pressing mechanism 14. The operating knob 11 is used to provide power, and the transmission mechanism 12 is used to transmit the power to the dial 13, thereby driving the dial 13 to move. The pre-pressing mechanism 14 can drive the dial 13 to move and make the dial 13 contact or bite with the operating disk 31 of the camera 3 with a certain preset pressure. Then, through the cooperation of the operating knob 11 and the transmission mechanism 12, the dial 13 can drive the operating disk 31 to rotate synchronously, thereby realizing the operation of the camera 3, so as to realize the functions of accessing the camera 3 including setting the aperture size or sensitivity and quickly setting the shutter speed. The dial 13 can bite (engage) with the operating disk 31, and the power is provided by rotating the operating knob 11. The transmission mechanism 12 transmits the rotational power to the dial 13. After the pre-pressing mechanism 14 makes the dial 13 contact with the operating disk 31, it synchronously drives the operating disk 31 to rotate.

[0036] Since the pre-pressing mechanism 14 can make the dial 13 and the operating disk 31 engage with each other with a preset pressure, it can effectively ensure that the operating disk 31 rotates synchronously with the dial 13, and there will be no slipping between the dial 13 and the operating disk 31 due to insufficient force applied during operation, or the operating disk 31 will be crushed or damaged due to excessive force applied. This makes the operation of the operating disk 31 of the camera 3 more convenient and quick, and the operation feel is comfortable.

[0037] The pre-pressing mechanism 14 includes a first swing bracket 141, a second swing bracket 142, a fixing seat 143 and a hinge shaft 144. The fixing seat 143 is provided with a first mounting hole 1431. The hinge shaft 144 is arranged in the first mounting hole 1431. The first swing bracket 141 and the second swing bracket 142 are movably connected through the hinge shaft 144. The dial 13 is connected to the first swing bracket 141. The second swing bracket 142 has a first position and a second position, and the first swing bracket 141 has a third position and a fourth position. The second swing bracket 142 can switch between the first position and the second position under the action of an external force, and synchronously drive the first swing bracket 141 to switch between the third position and the fourth position. When the second swing bracket 142 is in the first position, the first swing bracket 141 moves to the third position, and the dial 13 is separated from the operating disk 31. When the second swing bracket 142 is in the second position, the first swing bracket 141 moves to the fourth position, and the dial 13 abuts against the operating disk 31.

[0038] Before the dial device 1 is installed in the waterproof housing of the camera 3, the second swing bracket 142 is located at the first position, the first swing bracket 141 is located at the third position, and the dial 13 is separated from the operating panel 31. As the dial device 1 is installed in the waterproof housing of the camera 3, the second swing bracket 142 abuts against the inner wall of the waterproof housing 2 of the camera 3, and under the external force applied by the waterproof housing of the camera 3 to the second swing bracket 142, the second swing bracket 142 switches from the first position to the second position, and at this time, the first swing bracket 141 also switches from the third position to the fourth position synchronously, synchronously driving the dial 13 to abut against the operating panel 31, and the dial 13 can be pressed on the operating panel 31 with a preset pressure, and tightly abut (bite or mesh) with the operating panel 31.

[0039] The pre-stressing mechanism 14 also includes a first spring 145, which is arranged between the first swing bracket 141 and the second swing bracket 142. The second swing bracket 142 includes a first swing portion 1421 and a second swing portion 1422. The first swing portion 1421 and the second swing portion 1422 are configured to form a second swing bracket 142 with a substantially L-shaped structure. The first swing bracket 141 is arranged between the first swing portion 1421 and the second swing portion 1422, and the first spring 145 is arranged between the first swing portion 1421 and the first swing bracket 141. The force applied by the waterproof housing of the camera 3 to the second swing portion 1422 makes the first swing portion 1421 squeeze the first spring 145 when the second swing bracket 142 is switched to the second position. Under the action of the first spring 145, the first swing bracket 141 is switched to the fourth position, driving the dial 13 to move to abut (engage or mesh) with the operating panel 31. At this time, since the force applied by the waterproof shell of the camera 3 to the second swing part 1422 is not canceled, the first spring 145 is compressed and arranged between the first swing bracket 141 and the second swing bracket 142, so that the first swing bracket 141 can stably provide pressure to the operating disk 31 through the dial 13, so that the preset pressure is stable during the entire operation process, the operating disk 31 can rotate stably, and there is no need to apply additional force to the operating disk 31, which facilitates the addition operation.

[0040] It should be further explained that the aforementioned preset pressure can be adjusted by adjusting the elastic coefficient of the first spring 145 , specifically, to enable the dial 13 to abut against the operating disk 31 without damaging or crushing the operating disk 31 .

[0041] Furthermore, in order to more intuitively and clearly describe the operation process of the dial device 1, it is stipulated that when the second swing bracket 142 is in the first position, the first swing part 1421 is roughly horizontally arranged, the second swing part 1422 is vertically arranged, the first swing bracket 141 is horizontally arranged below the first swing part 1421, and the dial 13 is correspondingly arranged above the operating disk 31. When the second swing bracket 142 switches from the first position to the second position, the first swing part 1421 rotates downward around the hinge shaft 144, and under the action of the first spring 145 (elastic restoring force), the first swing bracket 141 rotates downward around the hinge shaft 144, so that the dial 13 moves downward and abuts against the operating disk 31.

[0042] The preload mechanism 14 further includes a second spring 146, which is disposed between the second swing bracket 142 and the fixed seat 143. When the second swing bracket 142 is in the second position, the first swing bracket 141 moves to the fourth position, and the second spring 146 is compressed and disposed between the second swing bracket 142 and the fixed seat 143. When the second swing portion 1422 of the second swing bracket 142 rotates under the external force of the waterproof housing of the camera 3, the second spring 146 is squeezed and disposed between the second swing portion 1422 and the fixed seat 143. As the external force of the waterproof housing of the camera 3 is cancelled, under the elastic restoring force of the second spring 146, the second swing portion 1422 and the first swing portion 1421 rotate, so that the second swing bracket 142 returns to the first position, and under the synchronous action of the first spring 145, the first swing bracket 141 returns to the third position, at which time the dial 13 and the operating panel 31 are separated.

[0043] Furthermore, in order to further ensure that the preset pressure of the dial 13 on the operating disk 31 is stable and effective, a limiter 147 is further provided on the second swing bracket 142. The limiter 147 is used to limit the rotation of the first swing bracket 141. The setting of the limiter 147 can limit the limit position of the first swing bracket 141 when it rotates downward. Specifically, the limiter 147 is provided on the second swing portion 1422. The first swing bracket 141 stops moving under the action of the limiter 147. As the second swing portion 1422 continues to move, the first swing portion 1421 continues to squeeze the first spring 145. Therefore, under the joint action of the first spring 145 and the limiter 147, the preset pressure applied by the dial 13 to the operating disk 31 is further increased, which can effectively prevent the dial 13 and the operating disk 31 from slipping against each other. The limiter 147 can be a limit screw.

[0044] The transmission mechanism 12 includes a first transmission assembly 121, a second transmission assembly 122 and a third transmission assembly 123. The first transmission assembly 121 is connected to the operating knob 11, the third transmission assembly 123 is connected to the dial 13, and the second transmission assembly 122 is arranged between the first transmission assembly 121 and the third transmission assembly 123. The operating knob 11 can drive the first transmission assembly 121 to rotate around the first axis A, and drive the second transmission assembly 122 to rotate, so that the third transmission assembly 123 rotates around the second axis B, and the first axis A and the second axis B are perpendicular to each other. Through the first transmission assembly 121, the second transmission assembly 122 and the third transmission assembly 123, not only can the rotational power of the operating knob 11 be transmitted to the dial 13, and the operating disk 31 can be synchronously driven to rotate through the dial 13, but also the rotational power of the operating knob 11 can be redirected, so that an integrated design can be realized, and the occupied volume of the entire dial device 1 can be effectively reduced, so as to adapt to the limited space in the waterproof housing of the camera 3.

[0045] Specifically, the first transmission assembly 121 includes a first transmission shaft 1211 and a first transmission gear 1212; the second transmission assembly 122 includes a second transmission shaft 1221, a second transmission gear 1222, a first bevel gear 1223, a second bevel gear 1224, a third transmission shaft 1225 and a third bevel gear 1226; the third transmission assembly 123 includes a fourth bevel gear 1231 and a fourth transmission shaft 1232; the two ends of the first transmission shaft 1211 are respectively connected to the operating knob 11 and the first transmission gear 1212; the two ends of the second transmission shaft 1221 are respectively connected to the second transmission gear 1222 and the first bevel gear 1223; the two ends of the third transmission shaft 1225 are respectively connected to the second bevel gear 1224 and the third bevel gear 1226; the two ends of the fourth transmission shaft 1232 are respectively connected to the fourth bevel gear 1231 and the dial 13; the second transmission gear 1222 and the first The transmission gear 1212 is meshed; the first bevel gear 1223 and the second bevel gear 1224 are meshed, and the axes of the first bevel gear 1223 and the second bevel gear 1224 are perpendicular to each other; the third bevel gear 1226 and the fourth bevel gear 1231 are meshed, and the axes of the third bevel gear 1226 and the fourth bevel gear 1231 are perpendicular to each other; the first transmission shaft 1211 and the second transmission shaft 1221 are arranged in a direction parallel to the first axis A, and the axes of the first transmission gear 1212, the second transmission gear 1222 and the first bevel gear 1223 are parallel to the first axis A; the fourth transmission shaft 1232 is arranged in a direction parallel to the second axis B, and the axis of the fourth bevel gear 1231 is parallel to the second axis B; the third transmission shaft 1225 is perpendicular to the first axis A and the second axis B, and the axes of the second bevel gear 1224 and the third bevel gear 1226 are perpendicular to the first axis A and the second axis B.

[0046] Furthermore, the first transmission gear 1212 and the second transmission gear 1222 are both spur gears.

[0047] Since the third transmission shaft 1225 is perpendicular to the first axis A and the second axis B, the second transmission shaft 1221 is arranged in parallel with the first axis A, the first bevel gear 1223 and the second bevel gear 1224 are meshed, the axes of the first bevel gear 1223 and the second bevel gear 1224 are perpendicular to each other, the third bevel gear 1226 and the fourth bevel gear 1231 are meshed, and the axes of the third bevel gear 1226 and the fourth bevel gear 1231 are perpendicular to each other, and the rotation direction of the transmitted power can be changed by the cooperation of the first transmission gear 1212, the second transmission gear 1222, the first bevel gear 1223 and the second bevel gear 1224, and then since the fourth transmission shaft 1232 is parallel to the second axis B, the rotation direction of the transmitted power is changed again by the cooperation of the third bevel gear 1226 and the fourth bevel gear 1231, and finally the rotation direction of the dial 13 is adapted to the operating disk 31, which can drive

[0048] The operating dial 31 rotates.

[0051] In order to further protect the operating disk 31, a protective outer coating 132 is provided on the circumference of the dial 13. The protective outer coating 132 is made of a soft and wear-resistant material, such as rubber or silicone, and can serve as a protective structure of the dial 13. The shape is adapted to the toothed structure 131 on the circumference of the dial 13 to prevent the operating disk 31 from being damaged due to friction when the operating disk 31 and the dial 13 abut and rotate synchronously.

[0052] Furthermore, the dial 13 is a dual-material injection molding or structural part, the inner material is hard and high-strength, which improves its own strength and thus increases its service life, while the outer material is relatively soft and wear-resistant to prevent crushing or damage to the operating disk 31.
