[0002] In addition to traditional on-land photography, the demand for underwater photography is also gradually increasing. Waterproof protective cases and camera buoyancy rods are both commonly used auxiliary shooting devices in underwater photography.

[0003] The existing camera buoyancy rod has a hollow structure, and air can enter the inside of the buoyancy rod to promote the formation of buoyancy. That is to say, the existing camera buoyancy rod can only play a role in supporting the camera, floating in the water to prevent the camera from sinking. When the camera needs to be operated, the user must manually operate the camera, resulting in inconvenient use and a single function of the buoyancy rod. Summary of the Utility Model

[0058] In order to make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some, rather than all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0059] Please refer to Figure 1 , the photographic buoyancy rod 100 is used to be connected to an electronic device with a photographing function and can be used for photographing in water through the photographic buoyancy rod 100. The photographic buoyancy rod 100 is composed of a main body 10, a connecting member 30 and a signal amplifier 50. Specifically, a control member 11 is arranged on the front surface of the main body 10, and the control member 11 is used to control functions such as the switch and photographing of the photographic buoyancy rod. The connecting member 30 is obliquely connected to the top of the main body 10 and is used to be connected to the electronic device. The signal amplifier 50 can be arranged inside the photographic buoyancy rod 100 and extends upward from the control member 11 to the connecting member 30.

[0060] Please refer to Figure 1 and Figure 2, the main body 10 is a long cylinder. The main body 10 successively includes an upper cover 13, an outer shell 15, and a bottom cover 17 from top to bottom. Specifically, the upper cover 13 is fixedly installed at one end of the outer shell 15, the top of the upper cover 13 is not closed while the bottom of the upper cover 13 closes one end of the outer shell 15, and the top and bottom are inclined relative to the outer shell 15. A second through hole 131 ( Figure 3 ) is provided at the bottom of the upper cover 13 near the control member 11, and the second through hole 131 communicates with the control member 11.

[0061] Please refer to Figure 2 and Figure 3 , the outer shell 15 is a rod-shaped structure with a closed top and an open bottom, the top is an inclined surface, and the inclination angle of the top of the outer shell is the same as the inclination angle of the bottom of the upper cover. One side of the outer shell 15 near the control member 11 is a platform surface 155, and the platform surface 155 is a flat and smooth surface. An inwardly recessed rectangular groove 151 is formed at the upper part of the front surface of the outer shell 15 near the upper cover 13. The groove 151 is formed by a part of the platform surface 155 recessing inward relative to the platform surface 155, that is, the top end of the groove 151 is flush with the platform surface 155. The groove 151 is used to accommodate the control member 11. When the control member 11 is embedded in the groove 151, the cover body 113 of the control member 11 is flush with the platform surface 155. Setting the platform surface 155 as a flat surface not only makes it flush with the outer surface of the control member 11, maintaining the flatness of the outer shell 15, but also meets the requirement for the placement of the user's fingers when holding, making the holding more stable. It can be understood that the platform surface 155 and the control member 11 can be simultaneously set as curved surfaces 157, or one of the platform surface 155 and the control member 11 can be set as a curved surface. The other surfaces of the outer shell 15 except the platform surface 155 are set as curved surfaces 157. Through the setting of the curved surfaces 157, there are no obvious edges and corners at the rear part of the main body 10, so that when the user holds the main body 10, the palm can naturally bend and wrap around the curved surface 157, and the user's holding is more stable and more comfortable. The inside of the outer shell 15 is hollow, forming a buoyancy chamber 153. The buoyancy chamber 153 is filled with air, so that the photographic buoyancy rod 100 floats in water. In one embodiment, no components are provided in the buoyancy chamber 153. Since the density of the air in the buoyancy chamber 153 is less than the density of water, the photographic buoyancy rod 100 can float on the water surface through the buoyancy chamber 153. In another embodiment, a sponge is provided in the buoyancy chamber 153. Since the density of the sponge is less than the density of water, the photographic buoyancy rod 100 can float on the water surface through the buoyancy chamber 153. It can be understood that the sponge can be replaced with other items with a density less than that of water. It can be understood that the buoyancy structure of the photographic buoyancy rod 100 is not limited to the two structures described in the above embodiments.

[0062] The bottom cover 17 is snap-fitted to the bottom of the outer shell 15. When the bottom cover 17 and the outer shell 15 are connected, the bottom cover 17 forms a closure for the bottom of the buoyancy chamber 153. In this embodiment, a wire-hanging hole 171 is provided at one end of the bottom cover 17 away from the control member 11. The wire-hanging hole 171 can be connected to a hanging rope or pendant with a rope buckle, facilitating the user to carry and decorate. An installation hole 173 is provided in the middle of the bottom of the bottom cover 17. The installation hole 173 can be set to be connected in cooperation with a screw rod for installing a bracket or a hanging rope with a screw rod member. The photographic buoyancy rod 100 of this embodiment provides two ways of connecting the hanging rope.

[0063] The upper cover 13 and the outer shell 15 can be set as an integrally formed structure or a detachable connection structure, and the outer shell 15 and the bottom cover 17 can be set as an integrally formed structure or a detachable connection structure, as long as the internal sealing state of the buoyancy chamber 153 is ensured.

[0064] Please refer to Figure 2 , in the existing design, the control member of the buoyancy rod used underwater is designed as a trigger buckle. When the trigger buckle is used, it will block the screen of the electronic device, and the user cannot see the picture they shoot, and the feedback of pressing the trigger buckle is not good. The control member 11 of this embodiment abandons the traditional trigger buckle design and adopts an electronic panel control. The control member 11 is installed in the groove 151. The control member 11 includes a housing 111 and a cover 113. The housing 111 is fixedly installed in the groove 151. After the cover 113 covers the housing 111, a hollow accommodation space 1111 is formed inside. An electronic component 115 is arranged in the accommodation space 1111. The top surface of the cover 113 is flush with the platform surface 155.

[0065] Specifically, the electronic component 115 includes a hardware board 1151 connected to the cover 113, a circuit board 1153 connected to the hardware board 1151, and a power supply 1155 for powering the control member 11. A plurality of independent keys are distributed on the cover 113, and the plurality of keys correspond to various functions such as switch, shutter, and adjustment. The hardware board 1151 is provided with a plurality of holes corresponding to the keys of the cover 113, and the sizes and shapes of the plurality of holes are not specifically limited. A plurality of electrical contact units 1152 are arranged on one side of the circuit board 1153 close to the hardware board 1153. Please refer to Figure 3, multiple electrical contact units 1152 pass through multiple holes in the hardware board 1151 and contact multiple buttons on the cover 113. When the user touches the cover 113, a force is applied to the cover 113, causing the cover 113 to deform and squeeze the electrical contact units 1152, and then a command is issued by the circuit board 1153. An indicator light 1131 is also provided on the control member 113 to indicate the working status, power level, etc. of the photographic buoy 100. The user can understand whether there is an operation error according to the indicator light 1131. Through the control member 11, the user can easily complete the operation of photographing with the electronic device underwater without blocking the screen of the electronic device. Compared with traditional buoys, the operation is more convenient and more practical.

[0066] Please refer to Figure 2 and Figure 3 , a connecting member 30 includes a connecting plate 31 connected to the top of the upper cover 13 and a plurality of limiting plates 33 extending from the connecting plate 31 away from the housing 15. The connecting plate 31 is inclined, and the inclination degree is the same as that of the top of the upper cover 13, so that the connecting plate 31 can be clamped on the upper cover 13. The limiting plates 33 extend perpendicular to the upper surface of the connecting plate 31, so that the limiting plates 33 are inclined toward the control member 11 on one side relative to the main body 10. When the electronic device is connected to the connecting member 30, the screen of the electronic device faces the control member 11. The inclined connecting member 30 makes the adjustable angle of the electronic device on the side close to the user larger, making it more convenient to use.

[0067] Please refer to Figures 2 - 4 , the plurality of limiting plates 33 are arranged at intervals, and a rotation space 335 is formed between two limiting plates 33. In this embodiment, the number of limiting plates 33 is three, in the shape of a three-claw. The limiting plate 33 includes a U-shaped body 331 and a cover plate 333. Through holes 3313 are provided at corresponding positions on the tops of the body 331 and the cover plate 333. Protrusions are formed on one side of the limiting plates 33 on both sides away from the middle limiting plate 33, and the through holes 3313 penetrate through the protrusions of the limiting plates 33 on both sides. The middle limiting plate 33 does not have protrusions, so the two sides of the middle limiting plate 33 are flat structures. Each through hole 3313 is aligned, and a screw (not shown in the figure) passes through the through hole 3313 and the electronic device connection mechanism, so that the electronic device is rotatably connected to the connecting member 30. A receiving groove 3311 is recessed on the inner side of the body 331, and a third through hole 311 penetrating the connecting plate 31 is formed at the connection between the receiving groove 3311 and the connecting plate 31. The size of the receiving groove 3311 is set to just accommodate the size of the signal amplifier 50, so that the signal amplifier 50 is just clamped in the receiving groove 3311 without displacement. During use, the cover plate 333 completely covers the signal amplifier 50, thus preventing water from contacting the signal amplifier 50.

[0068] Most of the floating rods on the market currently use a trigger to drive a mechanical structure to complete photography. The reason why there is no floating rod with Bluetooth settings is that when operating in environments such as fresh water or sea water, the response range of wireless signals such as Bluetooth signals will decrease as the salinity of the water increases. The photographic floating rod 100 of this embodiment adds a signal amplifier on the basis of the traditional floating rod, expanding the response range of the wireless signal. The photographic floating rod 100 can be remotely controlled to take pictures through Bluetooth connection with a floating rod device.

[0069] Please refer to Figure 5 , the photographic floating rod 100 is also provided with a wireless signal receiving device 70, and the photographic floating rod 100 and the electronic device are interactively connected through wireless signals such as Bluetooth. It can be understood that the photographic floating rod 100 can also be interactively connected with the electronic device through an external mechanical structure.

[0070] Specifically, in the present utility model, a Bluetooth module (wireless module) 71 is connected to the circuit board of an existing electronic device with a photographic function such as a camera, a mobile phone, and a tablet computer (the camera is exemplified in this embodiment). The Bluetooth module 71 of the photographic floating rod 100 is Bluetooth-connected to the Bluetooth module 71 on the camera to realize the control of the photographic floating rod 100 over the camera. When the user needs to take a self-portrait or group photo, without the help of others and without turning on the delayed photography function, the photographic floating rod 100 can be directly installed on the camera. The user holds the photographic floating rod 100 and sends a control signal through the photographic floating rod 100. The control signal is amplified by the signal amplifier 50 and then transmitted to the Bluetooth module 71. The Bluetooth module 71 transmits the control signal to the main control circuit of the electronic device with a photographic function. After being processed by the main control circuit, it controls the image capture unit to take pictures. The user can remotely control the mobile phone to take pictures at a short distance, or at a distance of more than ten meters or even farther. Its operation is simple, the control is safe and reliable, and the practicability is strong. It should be noted that the embodiment of the present utility model does not limit this control method with Bluetooth. Specifically, it can also be other wireless connection control methods, or other wired connections (such as connecting through a Type-C to realize control operations or using a robotic arm and other structures to realize control operations).

[0071] Please refer to Figures 2 to 4, in this embodiment, the signal amplifier 50 is an antenna. It can be understood that the signal amplifier 50 can also be other devices for amplifying signals. One end of the signal amplifier 50 is connected to the circuit board 1153, and the other end extends upward and successively passes through the first through hole 1113 of the housing 111 and the second through hole 131 of the upper cover 13, then passes through the third through hole 311 of the connecting plate 31, and finally is snap-fitted into the receiving groove 3311. The first through hole 1113, the second through hole 131, the third through hole 311, the receiving groove 3311, the upper cover 13 and the receiving space 1111 are communicated with each other. It can be understood that the position of the signal amplifier 50 can be located at any one of the plurality of limiting plates. It can be understood that the number of the signal amplifiers 50 can be multiple, and no specific limitation is made.

[0072] In the photographic buoyancy rod 100 of the present utility model, by providing the control member 11 of the electronic component, the problems of poor key feedback and screen occlusion when using a trigger in a traditional buoyancy rod are solved. The control of the control member 11 makes the photographic buoyancy rod 100 more intelligent, convenient and more operable. By providing the signal amplifier 50, the problem of poor signal response of wireless signals in waters with high salinity is overcome. Thus, the photographic buoyancy rod 100 of the present utility model can remotely control an electronic device through wireless signals such as Bluetooth, improving the convenience of operation.

[0073] So far, the technical solution of the present utility model has been described in combination with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present utility model is obviously not limited to these specific embodiments. Without departing from the principle of the present utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present utility model.
