Description
Technical Field
[0001] This utility model relates to the field of control component design, and in particular to a highly sensitive and durable fine-tuning knob. Background Technology
[0002] A knob is a manual control element that operates equipment by rotating or pulling it out. Based on function, it can be divided into two types: continuous multi-rotation (360° rotation) and fixed-position rotation. Knobs come in various shapes, including four basic categories: circular, polygonal, pointer-shaped, and rotary. They are widely used in industrial control, home appliances, medical instruments, and other fields. Knob design must balance information prompts, operating logic, and ergonomics, achieving precise control through scale markings and tactile textures.
[0003] The core principle of a knob is to change the mechanical contact state or electrical signal through rotation, thereby controlling the parameters or functions of the device. Its basic components include the knob body, the rotating shaft, and the contact point / trigger arm. It changes the circuit connection state through physical displacement; or it triggers the rotation of a magnet by rotating the knob, which is converted into a magnetic sensor that captures the angle change and then into a signal that is decoded by an electronic chip.
[0004] The lifespan of knobs on the market is generally around 5,000 cycles, but when a knob is damaged, the entire knob needs to be replaced. When used in positions that require frequent adjustments, the lifespan of the knob is relatively short. In addition, the turning pressure of knobs on the market cannot be controlled, resulting in an inability to adjust the feel when rotating. In the gaming equipment industry, the operating feel will seriously affect the actual operation of the game. Therefore, it is necessary to design a new highly sensitive and durable fine-tuning knob to solve the above problems. Utility Model Content
[0005] To overcome the shortcomings mentioned above, this utility model provides a technical solution that can solve the above problems.
[0006] A highly sensitive and durable fine-tuning knob includes a knob base, a rotating shaft, a turntable, a sensor positioning base, a photoelectric sensor, and a tactile adjuster;
[0007] The rotating shaft is rotatably mounted in the knob seat, the turntable is fixedly mounted on the rotating shaft, the sensor positioning seat is fixedly mounted on the side of the knob seat, the photoelectric sensor is fixedly mounted on the bottom of the sensor positioning seat, the photoelectric sensor has a U-shaped detection groove formed on it, and the turntable is fitted into the U-shaped detection groove with clearance fit.
[0008] The tactile adjuster includes a side plate, an adjusting bolt, a rubber assembly, and a gear. The gear is fixedly mounted on the rotating shaft, the side plate is fixedly mounted on the bottom side of the knob seat, the adjusting bolt is screwed onto the side plate, and the rubber assembly is fixedly mounted on the inner end of the adjusting bolt, with the inner end of the rubber assembly abutting against the gear.
[0009] Furthermore, the side plate has threaded holes formed therein, and the adjusting bolts are screwed into the threaded holes.
[0010] Furthermore, the upper end of the rotating shaft extends out of the knob seat, and a twist handle is fixedly installed on the upper end of the rotating shaft.
[0011] Furthermore: the upper end of the rotating shaft is formed with a first external thread, and the twisting handle is screwed and installed at the first external thread.
[0012] Furthermore: a rolling bearing is fitted between the knob seat and the rotating shaft, and bearing mounting grooves are formed at the bottom end of the twist handle and the top end of the knob seat, with the rolling bearing fitted between the two bearing mounting grooves.
[0013] Furthermore, the outer side of the twist handle is integrally formed with anti-slip teeth.
[0014] Furthermore: the lower end of the rotating shaft is formed with a second external thread, the gear is fixedly installed on the upper end of the turntable, and the middle part of both the gear and the turntable is formed with internal threads, and the second external thread is helically fitted into the internal thread.
[0015] Furthermore, the turntable has several light-transmitting holes formed on it, and these holes are arranged in a circular array. The U-shaped detection groove of the photoelectric sensor detects the real-time position of the turntable through the light-transmitting holes.
[0016] Furthermore, both the sensor positioning base and the photoelectric sensor are provided in pairs.
[0017] Furthermore, the photoelectric sensor employs a slotted photoelectric switch.
[0018] Compared with the prior art, the beneficial effects of this utility model are:
[0019] 1. The rotating shaft rotates within the knob base. As the shaft rotates, the real-time position of the turntable can be detected through the U-shaped detection groove of the photoelectric sensor, thereby determining the rotation angle of the shaft. By replacing the traditional knob with photoelectric detection, high-precision rotation detection can be achieved, enabling fine-tuning of the angle.
[0020] 2. When the photoelectric sensor is damaged and detection errors occur, the problem can be resolved by replacing the photoelectric sensor alone, without having to replace the entire knob assembly, thus reducing maintenance costs;
[0021] 3. It is equipped with a feel adjuster, which can control the force of the rubber component pressing on the gear by turning the adjusting bolt, thereby realizing the adjustment of rotation pressure. Different pressures can be adjusted according to different application scenarios. It is suitable for fine adjustment when tightening and for large adjustment when loosening, which is convenient for practical application. At the same time, it can also control the feel of rotation, and the operating experience is better when applied to gaming devices.
