Detailed Description

For ease of understanding, the specific structure and operation of the present invention will be further described herein with reference to FIGS. 1-7:

the specific structure of the invention is shown in fig. 1-7, and the main structure of the invention comprises a rotating part 10, and the front surface of the rotating part 10 facing an operator forms an LED luminous surface. The rotary part 10 is rotatably fixed on the fixed seat 20, so that a user holds the rotary part 10 and then rotates and applies force, the rotary part 10 is controlled to generate rotary action based on the rotary seat, the encoder 30 generates follow-up reaction, and finally the signal output of the encoder 30 is used for controlling the LED luminous surface to generate follow-up color change. When in use, the interactive knob can be matched with software in the prior art to realize the purpose of color change of the LED luminous surface, but the following must be pointed out: the software that cooperates with the interactive knob is not an innovative part of the present invention nor an integral part of the present invention.

Furthermore, the universal interactive knob can be realized by the following two embodiments:

example 1:

as shown in fig. 1 to 4, the whole universal type interactive knob, namely, the present invention, comprises a rotating part 10, a fixed seat 20, a shaft sleeve 40, an encoder 30 and a damper 70 which are axially arranged in sequence. Wherein:

the rotary part 10 comprises a knob cover 11, and a light equalizing plate 12, a spacer bush 13 and a transparent connecting shaft 14 are axially and sequentially arranged in a cylinder cavity of the knob cover 11. During actual assembly, the light equalizing plate 12 is coaxially pressed at a hole shoulder in the cylinder cavity of the knob cover 11, and the pressing operation is realized through the spacer bush 13; the arrangement of the light-equalizing plate 12 can make the light diffuse and more uniform, and is more suitable for visual observation. The transparent connecting shaft 14 is fixed in the knob cover 11 by the set screw 90, and the spacer 13 is pressed axially by the transparent connecting shaft 14 so as to press the light equalizing plate 12.

The turning operation of the entire knob cover 11 is achieved by a turning bearing 80 located at the end of the knob cover 11. The outer ring of the slewing bearing 80 is fixed at the tail end of the knob cover 11; while the inner ring of the swivel bearing 80 is interference fit on the bearing seat 42 and is clamped and positioned by the shaft clamp 44. The whole bearing seat 42 is sleeved on the outer wall of the shaft sleeve 40, and sequentially passes through the flange 41 at the shaft sleeve 40 and the fixing plate 16 and then is screwed on the bearing seat 42 through axial screws, so that the purpose of integrated fixedly connecting the bearing seat 42, the fixing seat 20 and the shaft sleeve 40 is realized.

Encoder 30 is shown in fig. 1-4 as being secured to the end of sleeve 40. To ensure the operational feel of the present invention, the present invention further adds a damper 70 as shown in fig. 3-4 to the structure of fig. 1-2. Specifically, a fixed cylinder 60 is first coaxially and downstream from the rear end of the boss 40. On the one hand, the cylinder cavity of the fixed cylinder 60 constitutes a housing cavity of the encoder 30; on the other hand, the damper 70 is fixed to the rear end of the fixed cylinder 60, thereby achieving a dynamic damping effect of the rotational force at the rotating part 10 by being coupled with the power of the encoder 30.

Example 2:

as shown in fig. 5-6, the entire universal interactive knob now includes the rotary part 10, the conductive slip ring 100, the damper 70 and the encoder 30, which are axially arranged in sequence. Wherein:

the rotary part 10 comprises a knob cover 11, and a lens 15, a light equalizing plate 12, an LED lamp plate 50 and a fixing plate 16 are axially and sequentially arranged in a barrel cavity of the knob cover 11. In actual assembly, the spigot of the lens 15 and the light-equalizing plate 12 which are integrated is fixed at the head end of the knob cover 11. The LED lamp panel 50 is directly fixed at the head end surface of the fixing plate 16, and the tail end surface of the fixing plate 16 extends coaxially with the rotating shaft 10a, so as to form a power fit with the damper 70.

The damper 70 serves as a core structure of the present embodiment, and skillfully plays a role in the assembly structure after the front opening. The head end of the damper 70 is fixed to the mounting plate 21 of the fixing base 20 through the connecting rod 22, and the tail end is fixed to the encoder 30; in addition, the front end of the damper 70 is also fixed with a conductive slip ring 100, so that the fixed seat 20, the conductive slip ring 100, the damper 70 and the encoder 30 together form a static member in a three-dimensional space. The power output shaft of the rotating part 10, i.e. the rotating shaft 10a, is formed by coaxially extending the tail end of the fixing plate 16 outwards. The rotation shaft 10a is connected with the damper 70 by power as shown in fig. 5 to 6, so that the rotation power of the rotation part 10 is inputted into the damper 70 and is inputted into the encoder 30 again from the damper 70. Of course, a slip ring rotor should also be coaxially disposed at the input shaft of the damper 70 in order to achieve the power access function of the LED lamp panel 50.

In actual operation, any of the above embodiments is arranged in an array manner as shown in fig. 7, and other planar or even three-dimensional arrangements may be adopted. After the layout is completed, through rotating any rotating part 10, the rotating part 10 rotates and simultaneously increases the operation handfeel through the damper 70, and the color of the LED luminous surface is changed through the encoder 30, so that the color dazzling purpose of the whole interactive wall can be realized, and the interactive wall is extremely beneficial to the scientific and teaching field with higher manual operability requirements or the advertising field with higher color richness requirements.

The interactive wall can be used as a visual art device or space decoration; because each universal interactive knob is used as a pixel point in the area, a viewer can rotate each universal interactive knob to adjust different colors and brightness required by each pixel point, so that a colorful pattern is formed on the whole array structure, and finally, the complete pattern forming requirement is realized. Compared with the traditional lamp box, lamp belt and other modes, the interactive wall scheme provided by the invention has stronger interactivity, richer colors, more various modeling and pattern changes and better visual effect; typical scenes of applications include malls, public spaces, playgrounds, and the like.

Of course, the foregoing is illustrative of two embodiments of the present invention. In actual operation, for example, the transparent connecting shaft 14 is changed to other axial propping structures, or the swivel bearing 80 is replaced by a swivel ring, and even the various groups of universal interactive knobs described in the above embodiments are combined in other array modes or even in non-array modes, or are changed in color by remote control, etc.; the operation mode of each group of universal interactive knobs not only comprises manual adjustment, but also comprises the combination of a gesture sensor and a gesture control array; or combining with a somatosensory sensor to display a human shadow or an interactive picture; or combined with a color sensor, can acquire the color of clothes of a viewer, automatically switch, form a chameleon effect and the like, and the conventional changes made on the basis of knowing the technical structure of the invention are all considered to be equivalent or similar designs and fall within the protection scope of the invention.
