[0026] The following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the drawings in the embodiments of this application. It can be understood that the specific embodiments described here are only used to explain this application, rather than limiting this application. Additionally, it should be noted that for the sake of description, only parts related to this application rather than all structures are shown in the drawings. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of this application.
[0027] It should be noted that all directional indications in the embodiments of the present application, such as up, down, left, right, front, back... are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture as shown in the drawings. If the specific posture changes, the directional indications will also change accordingly.
[0028] In addition, the descriptions involving "first", "second", etc. in the present application are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present application.
[0029] Refer to Figure 1 , Figure 1 which is an exploded view of a knob screen device provided by the present application.
[0030] Refer to Figure 2 , Figure 2 which is a partial enlarged view of a knob screen device provided by the present application.
[0031] The knob screen device includes: a transparent window 10, a display panel 20, a panel support frame 30, a rotating housing 40, a main board 50 and a base 60. A Hall sensor 510, a magnet 520 and a roller 530 are provided on the main board 50.
[0032] In some embodiments, the display panel 20 is preferably formed by bonding a glass panel or an acrylic panel to the screen.
[0033] In some embodiments, the panel support frame 30 is made of a semi-transparent material. Among them, background light beads are also provided on the main board 50, and the semi-transparent support frame can achieve an edge backlight effect.
[0034] Combined with Figure 1 and Figure 2 , the inner side of the rotating housing 40 is provided with a track 410 that matches the roller 530.
[0035] Among them, the Hall sensor 510 and the magnet 520 are respectively provided on two sides of the main board.
[0036] It can be understood that the Hall sensor 510 and the magnet 520 are respectively provided on two sides of the main board 50, which can effectively utilize the thickness of the main board 50, thereby reducing the thickness of the overall device.
[0037] Further, the magnet 520 and the Hall sensor 510 are located on different sides of the main board 50, which helps to miniaturize the structure of this part. Users can obtain a more delicate knob experience. The smaller the right roller 530 is, the more turns the magnet 520 rotates when the roller 530 rotates by the same angle, and the more pulse signals the Hall sensor 510 can distinguish, that is, the higher the rotation sensitivity is.
[0038] Wherein, the roller 530 is coaxially connected to the magnet 520, and the rotation of the roller 530 drives the rotation of the magnet 520.
[0039] Wherein, when the magnet 520 rotates, the relative position between the Hall sensor 510 and the magnet 520 remains unchanged.
[0040] Further, the base 60 is provided with an opening 610 matching the roller 530.
[0041] It can be understood that the roller 530 is embedded in the opening 610 of the base 60, making full use of the space and effectively reducing the overall thickness of the knob device.
[0042] Refer to Figure 3 , Figure 3 is a perspective view of a knob screen device provided by the present application.
[0043] It can be understood that the entire knob screen device is delicate and concise, suitable for a variety of products, and easy to install.
[0044] Wherein, the roller 530 is elastic and slightly higher than the plane of the main board 50, so that it protrudes from the surface of the main board 50.
[0045] It can be understood that the roller 530 contacts the track 410 on the inner side of the rotating housing 40. When the rotating housing 40 rotates, relative movement occurs between the track 410 and the roller 530, and the friction force drives the rotation of the roller 530.
[0046] In some embodiments, the knob device is further provided with a voice control module 70. The voice control module 70 can execute corresponding programs when receiving voice commands, and the UI interface of the display panel 20 will display the corresponding programs, enriching the user's usage methods.
[0047] Refer to Figure 4 , Figure 4 is a flowchart of a control method for a knob screen device provided by the present application.
[0048] In some embodiments, the control method includes:
[0049] The first step is to rotate the rotating housing to drive the relative movement of the roller through the rotation of the rotating housing.
[0050] In the second step, the movement of the roller drives the rotation of the magnet;
[0051] In the third step, the Hall sensor senses the rotation of the magnet;
[0052] In the fourth step, the system determines the rotation data through the pulse signal sent by the Hall sensor;
[0053] Finally, the system executes the corresponding program.
[0054] Different from the prior art, the present invention provides a knob screen device, which includes: a transparent window, a display panel, a panel support frame, a rotating housing, a main board and a base, and the main board is provided with a Hall sensor, a magnet and a roller. Through the above method, the knob screen device can be delicately constructed, easy to operate and sensitive to response.
[0055] In the embodiments provided in this application, it should be understood that the disclosed methods and structures can be implemented in other ways. For example, the structural embodiments described above are only illustrative, and there may be other division methods in actual implementation, such as multiple units or components can be combined or integrated into another system, or some features can be ignored or not executed.
[0056] The above description is only an implementation method of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
