Description

Technical Field

[0001] This utility model relates to the technical field of underwater photography equipment, and in particular to a waterproof structure for a mobile phone zoom knob with an underwater bearing. Background Technology

[0002] As we all know, underwater photography devices are mainly used to capture underwater scenes, and the captured scenes offer a completely new artistic aesthetic. In recent years, they have become increasingly popular among photographers. In terms of design, underwater photography devices often need to ensure that the interior is absolutely sealed to prevent water leakage. With the continuous upgrading of mobile phone shooting functions, mobile phones have now become a common device for underwater photographers. Therefore, waterproof underwater shooting cases are adapted to the shooting structure of mobile phones. The basic principle of these devices is to place the mobile phone inside the device (waterproof case) and then close the cover. The device's casing has many waterproof button structures or waterproof knob structures to meet the user's control of mobile phone photography, especially the operation of mobile phone zoom.

[0003] Currently, to achieve zoom operation on mobile phones, a knob is usually set on the casing to control zoom (mainly through a built-in communication circuit board, specifically including WIFI, Bluetooth, infrared, RF, etc.). For the waterproof structure of this type of knob, waterproofing is basically just relying on O-rings. However, there is a lot of contact friction between the knob shaft and the casing. In addition, the waterproof pressure of the O-ring results in a poor feel when operating the knob, leading to a poor product experience for consumers. Utility Model Content

[0004] To address the shortcomings of the existing technology, the purpose of this utility model is to provide a waterproof underwater zoom knob structure for mobile phones with bearings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A waterproof underwater zoom knob structure for a mobile phone with an underwater bearing includes a housing and a knob. The housing has an inner cavity and a channel communicating with the inner cavity on its surface. The knob includes a rotating cap and a rotating rod integrally connected to the rotating cap. The rotating rod passes through the channel and is connected to the channel via a bearing. The inner cavity has a circuit board with an encoder. The bottom end of the rotating rod is placed in the inner cavity and connected to the operating lever of the encoder. At least one waterproof rubber ring is provided at the port of the rotating rod and the channel.

[0007] Preferably, the bottom end of the rotating rod is locked to the connection between the channel and the inner cavity by a C-shaped retaining ring.

[0008] Preferably, a partition is provided in the inner cavity, and a battery cavity is formed in the inner cavity through the partition. A battery is installed in the battery cavity, and the battery is electrically connected to the circuit board.

[0009] Preferably, the circuit board integrates a microcontroller with Bluetooth functionality and a charge / discharge management circuit.

[0010] Preferably, the surface of the rotating cap is provided with anti-slip serrations.

[0011] Preferably, the housing has an outwardly protruding gripping portion on the side near the knob.

[0012] Preferably, the gripping part is provided with anti-slip texture.

[0013] By adopting the above-mentioned solution, this utility model uses a bearing design to prevent the knob's rotating rod from making surface-to-surface frictional contact with the channel. By using the bearing as a rotating connecting part, the rotational friction between components can be effectively reduced. After being equipped with a waterproof rubber ring, a sealed and waterproof knob operation can be achieved, which is also smooth. At the same time, combined with the rotation of the encoder, it relies on Bluetooth communication to meet the operation of mobile phone photography and zoom functions. Attached Figure Description

[0022] like Figures 1 to 5 As shown in the figure, this embodiment provides a waterproof underwater zoom knob structure for mobile phones with bearings, including a housing 1 and a knob 2. The housing 1 is provided with an inner cavity 3 and a channel 4 through the inner cavity 3 on its surface. The knob 2 includes a rotating cap 21 and a rotating rod 22 integrally connected to the rotating cap 21. The rotating rod 22 passes through the channel 4 and is connected to the channel 4 by a bearing 5. The inner cavity 3 is provided with a circuit board 6, and an encoder 7 is provided on the circuit board 6. The bottom end of the rotating rod 22 is placed in the inner cavity 3 and connected to the operating lever of the encoder 7. At least one waterproof rubber ring 8 is provided at the port of the rotating rod 22 and the channel 4.

[0023] The housing in this embodiment is an underwater waterproof housing for storing a mobile phone. The specific structure only needs to meet the requirement of waterproof storage for the phone. Regarding the rotation mechanism, the following steps are involved when assembling it with housing 1:

[0024] 1. First, assemble and fix the circuit board 6 with encoder 7 onto the housing 1;

[0025] 2. The knob 2's lever 22 is fitted with a waterproof rubber ring 8 (a waterproof sealing O-ring).

[0026] 3. Then install the bearing 5 onto the knob 2 rod 22 (interference fit);

[0027] 4. Then press the knob 2 with bearing 5 into the corresponding hole in channel 4;

[0028] 5. Finally, use the C-shaped retaining ring 9 to lock the knob 22.

[0029] In this embodiment, by using the bearing 5, the knob's lever does not make surface-to-surface frictional contact with the channel. By using the bearing 5 as a rotating connector, rotational friction between components can be effectively reduced. After equipping with the waterproof rubber ring 8, a sealed, waterproof, and smooth knob operation can be achieved.

[0030] Furthermore, this embodiment primarily enables Bluetooth communication and focusing with a mobile phone, thus requiring a power supply. Therefore, a partition 10 is provided within the inner cavity 3, forming a battery cavity 11. A battery 12 is installed in the battery cavity 11, and the battery 12 is electrically connected to the circuit board 6. The circuit board 6 integrates a microcontroller with Bluetooth functionality and a charge / discharge management circuit (power supply), and also includes an SWD programming interface, a reset circuit, and a crystal oscillator circuit. In this embodiment, the microcontroller can be an NRF51822-QFAC model, and the charge / discharge management circuit mainly consists of a charging management chip (TP4056X) and a voltage regulator (XC6701D332PR-G).

[0031] Furthermore, in order to facilitate the application of underwater force to the rotating cap 21 and avoid rotational slippage, the surface of the rotating cap 21 in this embodiment is provided with anti-slip serrations 23.

[0032] Furthermore, in order to facilitate gripping the housing 1 and to allow smooth rotation of the knob 2 when gripping, this embodiment provides an outwardly protruding gripping part 13 on the side of the housing 1 near the knob 2. At the same time, the gripping part 13 is provided with anti-slip texture 14 to prevent slipping when gripping.

[0033] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
