Description

Technical Field

[0001] This invention relates to the field of stepless knob technology, specifically a novel stepless knob for a central control screen. Background Technology

[0002] As is well known, a "stepless knob" for a central control screen usually refers to a type of knob that controls the vehicle's central control screen. This knob design allows users to adjust different functions or parameters on the screen by rotating it continuously, rather than having fixed scales or limits like a traditional switch. This stepless knob design is common in car central control screens, for example, for adjusting volume, zooming in and out of navigation maps, and adjusting the air conditioning temperature.

[0003] However, the existing center console's stepless knob assembly is not fully embedded within the product, resulting in the aluminum alloy knob protruding significantly above the main unit's thickness, typically by more than 20mm. The bearing is mounted on a plastic structural component, relying on it for fixation and limiting. Insufficient flatness leads to wobbling during rotation. Infrared ranging is used to sense knob rotation, requiring high flatness and deformation control of the structural component's mating surfaces. Furthermore, when compatible with motor vibration feedback, it is susceptible to vibration interference, leading to inaccurate ranging and knob malfunction. Infrared ranging, limited by structural characteristics, can only operate on a limited range and cannot detect subtle rotational changes, thus failing to achieve free adjustment of gears. Currently, photoelectric tracking sensors typically use metal structural components, increasing product weight and cost. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a novel stepless rotary knob for central control screens.

[0005] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: a novel stepless rotary knob for a central control screen, comprising an aluminum alloy frame, a main screen, a button board, a photoelectric tracking sensor, a lower cover, an aluminum alloy knob, a fully laminated touchscreen, a fixed bracket, a motor, a rotating bracket, a bearing, and silicone leather. The main screen is mounted on the aluminum alloy frame, the photoelectric tracking sensor is mounted on the button board, the button board is mounted at the bottom of the aluminum alloy frame, the lower cover is mounted at the bottom of the aluminum alloy frame, the fully laminated touchscreen is mounted on the fixed bracket, the bearing is positioned between the fixed bracket and the rotating bracket, the fixed bracket has threaded posts, and the fixed bracket is connected to the aluminum alloy frame through the threaded posts, the motor is mounted on the fixed bracket, and the silicone leather is attached to the aluminum alloy frame with a hole for clearance, the size of which is smaller than the outer diameter of the aluminum alloy knob.

[0006] To improve the engagement effect, in this embodiment, the fixed bracket is provided with bearing inner ring tightening ribs, first bearing ribs, threaded columns and motor limiting buckles. There are several first bearing ribs and several bearing inner ring tightening ribs.

[0007] To improve the engagement effect, in this embodiment, the rotating bracket is provided with a bearing limiting buckle, a second bearing limiting rib, a limiting groove, an aluminum alloy knob assembly buckle, an aluminum alloy knob fastening rib, and a photoelectric tracking sensor irradiation surface. The bearing is provided with a limiting groove, which matches the limiting post.

[0008] To improve stability, the present invention is improved in that the fully laminated touch screen is bonded to the fixed bracket with adhesive backing.

[0009] To improve stability, the present invention is improved in that the motor is attached to the fixed bracket by a foam pad and adhesive backing.

[0010] To improve stability, the present invention is improved by providing a plurality of threaded columns.

[0011] (III) Beneficial Effects Compared with the prior art, the present invention provides a novel stepless rotary knob for central control screens, which has the following beneficial effects: This novel stepless rotary knob for central control screens features an embedded design in its aluminum alloy knob, significantly reducing its thickness and achieving an ultra-thin design. The knob's bearings are secured by a metal structural component through a pressing fit, ensuring that the knob will not deform under stress during rotation, preventing instability or wobbling. A photoelectric tracking sensor detects the knob's rotation, converting light signals into electrical signals. After data processing and control, the position, speed, and direction of the target are calculated, preventing knob failure due to deformation or vibration feedback. The photoelectric tracking sensor can detect very subtle displacement changes, thus improving the knob's sensitivity. Furthermore, the corresponding illumination surface is planar, allowing for flexible adjustment of the number of settings according to product requirements. In this structure, the illumination surface of the photoelectric tracking sensor is made of plastic with a metallic paint finish, resulting in a lighter and lower-cost product. It also allows for flexible adjustment of the metallic paint color and fineness based on sensor performance requirements, greatly mitigating material limitations in photoelectric solutions.

The main screen 2 is mounted on the aluminum alloy frame 1. The photoelectric tracking sensor 4 is mounted on the button panel 3, which is located at the bottom of the aluminum alloy frame 1. The lower cover 5 is located at the bottom of the aluminum alloy frame 1. The fully laminated touchscreen 7 is mounted on the fixed bracket 8. The bearing 12 is located between the fixed bracket 8 and the rotating bracket 11. The fixed bracket 8 has a threaded post 16, which connects the fixed bracket 8 to the aluminum alloy frame 1. The motor 10 is mounted on the fixed bracket 8. The silicone leather 13 is attached to the aluminum alloy frame 1 and has an opening that avoids obstruction; the opening size is smaller than the outer diameter of the aluminum alloy knob 6.

[0015] To improve the engagement effect, in this embodiment, the fixed bracket 8 is provided with a bearing 12 inner ring tightening rib, a first bearing 12 rib, a threaded column 16 and a motor 10 limiting buckle. The first bearing 12 rib is provided in several units, and the bearing 12 inner ring tightening rib is provided in several units.

[0016] To improve the engagement effect, in this embodiment, the rotating bracket 11 is provided with a bearing 12 limiting buckle, a second bearing 12 limiting rib, a limiting groove 21, an aluminum alloy knob 6 assembly buckle, an aluminum alloy knob 6 tight fitting rib, and a photoelectric tracking sensor irradiation surface 24. The bearing 12 is provided with a limiting groove 21, which matches the limiting post 20.

[0017] To improve stability, in this embodiment, the fully laminated touch screen 7 is attached to the fixed bracket 8 with adhesive backing.

[0018] To improve stability, in this embodiment, the motor 10 is attached to the fixing bracket 8 by foam padding and adhesive backing.

[0019] To improve stability, in this embodiment, the threaded post 16 is provided with several of them.

[0020] In summary, during use, the knob structure adopts a modular embedded assembly. First, the fully laminated touchscreen 7 is attached to the fixed bracket 8 with adhesive backing. The motor 10 is then attached to the fixed bracket 8 with foam padding and adhesive backing. The foam cushioning prevents the motor 10 from vibrating and generating noise. The motor 10 is prevented from falling off by limiting ribs. The outer ring of the bearing 12 is fixed to the rotating bracket 11 by the bearing 12 limiting buckle. The bearing 12 is limited by the second bearing 12 limiting rib and reinforced with strong adhesive to ensure that it does not detach in the horizontal direction and cause free rotation. The fixed bracket 8 is connected to the inner ring of the bearing 12 by the first bearing 12 limiting rib and the tight-fitting rib of the bearing 12. The rotating bracket 11 is limited by the second bearing 12 limiting rib. The buckle connects to the outer ring of the bearing 12, thereby fixing the bracket 8 and the rotating bracket 11 together through the bearing 12. Then, the aluminum alloy knob 6 is fixed to the rotating bracket 11 by the aluminum alloy knob 6 mounting buckle and the aluminum alloy knob 6 fastening rib. The silicone leather 13 is attached to the aluminum alloy middle frame 1, with a hole to avoid gaps. The hole size is smaller than the outer diameter of the aluminum alloy knob 6, so that there is no gap in the front view of the product, ensuring the product's beautiful appearance. After the aluminum alloy knob 6 is assembled, it is embedded in the aluminum alloy middle frame 1. The fixing bracket 8 is provided with a positioning post, and the aluminum alloy middle frame 1 is provided with a positioning hole that matches the positioning post. Thus, the positioning post and positioning hole on the fixing bracket 8 are matched and positioned with the aluminum alloy middle frame 1. The photoelectric tracking sensor 4 is welded to the button plate 3. Plate 3 is locked and fixed to the aluminum alloy frame 1. The aluminum alloy frame 1 has an opening at the sensor position to avoid obstruction. The rotating bracket 11 is sprayed with metallic paint on the plane position corresponding to the photoelectric tracking sensor 4 to realize the photoelectric tracking sensing function. After the aluminum alloy knob 6 is assembled, the motor 10 and the touch screen are connected to the button plate 3 through FPC to realize the vibration feedback function. The principle of photoelectric tracking function: The advantages of the photoelectric tracking system are high precision and fast response. Since the light signal can propagate very fast, the photoelectric tracking system can track and control the target in real time. The photoelectric tracking system consists of three parts: photoelectric sensor, data processing and control unit. The light source is generally a laser or photodiode, which can emit a very narrow beam of light. The beam is focused by a lens. A beam of light is used to illuminate a target object. The target object reflects a portion of the light signal after being illuminated. A photoelectric sensor receives these reflected light signals. The photoelectric sensor typically includes a photosensitive element and a signal amplification circuit, converting the light signal into an electrical signal for acquisition. The electrical signal acquired by the photoelectric sensor is processed and analyzed by a data processing and control unit. The data processing and control unit can identify the target based on the information in the light signal and calculate parameters such as the target's position, velocity, and direction. Through the calculation and analysis of these parameters, the photoelectric tracking system can accurately track and locate the target. The calculated and analyzed data is transmitted to the motor 10 via the main chip. The motor 10 receives the photoelectric analysis parameters and senses the knob's movement.Simultaneously, vibration feedback is provided. In practical applications, the target can be controlled according to specific needs, such as achieving automatic target tracking or controlling the target's movement trajectory.
