Detailed Implementation

[0023] The specific embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but are not intended to limit the scope of this application.

[0024] When it comes to entertainment, there are usually requirements for the entertainment effect. For example, in display equipment, the more mysterious the content to be displayed, the better the final effect and the easier it is to satisfy the user's psychological needs.

[0025] In these devices, a simple motor drives a rotating structure to display different patterns, eventually stopping on a certain pattern without any sudden changes or surprises.

[0026] In this regard, such as Figures 1-4 As shown in the preferred embodiment of this application, a rotating device 10 includes: a first support 101, a second support 102, a rotating rod 103, a rotating wheel 104, a cap 105, and a motor 106.

[0027] The second support 102 is equipped with a limiting block 1021, which is located on the side of the second support 102 closest to the first support 101. A rotating rod 103 is rotatably connected to the first support 101. A rotating wheel 104 is a cylindrical structure, fixed to the rotating rod 103, and its cylindrical surface is evenly divided into at least two patterned areas 1041. A cap 105 is rotatably connected to the rotating rod 103, and includes an arc surface 1051 and a baffle 1052. The arc surface 1051 covers the outside of the rotating wheel 104, and its dimensions are the same as the dimensions of the patterned areas 1041. The baffle 1052 abuts against the limiting block 1021 when the cap 105 rotates. The motor 106 is fixed on the first bracket 101. The output shaft of the motor 106 is coaxially connected to the first bracket 101. The motor 106 is used to drive the rotating rod 103 to rotate. The rotating rod 103 drives the cap 105 to rotate through friction.

[0028] With the above scheme, the motor 106 drives the rotating rod 103, which is fixedly connected to the rotating wheel 104. Therefore, the rotating wheel 104 always rotates synchronously with the rotating rod 103. The cap 105 covering the rotating wheel 104 is rotatably connected to the rotating rod 103. The rotating rod 103 drives the cap 105 to rotate through friction.

[0029] Therefore, when the motor 106 drives the rotating rod 103, the rotating rod 103 simultaneously drives the rotating wheel 104 and the cap 105 to rotate. The pattern area 1041 of the rotating wheel 104, which is covered by the cap 105, is not visible. Therefore, when rotating, at least one pattern area 1041 on the rotating wheel 104 is in an unpredictable state.

[0030] At this time, when the cap 105 is rotated to the baffle 1052 is in contact with the limiting block 1021, because the limiting block 1021 is fixed with the support, the limiting force is much greater than the friction force, so the cap 105 stops rotating, and the rotating wheel 104 continues to rotate, the originally hidden pattern area 1041 is exposed, and the pattern there is suddenly displayed, achieving unexpected entertainment effect.

[0031] The rotating device 10 with mutation effect of the application can be applied to various equipment, such as awarding equipment and face changing equipment, to improve the entertainment of these equipment.

[0032] In order to improve the synchronization of the rotating wheel 104 and the cap 105 before reaching the limit, in an embodiment, the rotating device 10 can further include a damping bearing 107, which is installed between the cap 105 and the rotating rod 103, for increasing the friction force between the cap 105 and the rotating rod 103.

[0033] The design of adding the damping bearing 107 can increase the friction force between the cap 105 and the rotating rod 103, improve the synchronization of the rotating wheel 104 and the cap 105 before reaching the limit, make the device run more stably and controllably, further optimize the entertainment effect, and avoid the undesirable display effect caused by poor synchronization.

[0034] In an embodiment, the pattern of the arc surface 1051 is the same as the pattern of one of the pattern areas 1041.

[0035] From the visual effect, the same pattern setting makes the whole display process have a certain coherence, and it is not easy for the user to prematurely perceive the change rule of the pattern area 1041. This confusion increases the user's expectation of the rotation result, attracts the user's continuous attention, and improves the attraction of the rotating device 10 in the entertainment scene.

[0036] In an embodiment, the rotating device 10 further includes a plurality of position sensors 108 distributed in the circumference, and the position sensors 108 correspond one-to-one to the pattern areas 1041; the rotating rod 103 is provided with a baffle 1031 close to the motor 106, the baffle 1031 extends along the radial direction of the rotating rod 103, and the baffle 1031 can trigger any position sensor 108 when the rotating rod 103 rotates.

[0037] Because the position sensors 108 correspond one-to-one to the pattern areas 1041, when the baffle 1031 triggers the position sensor 108 when the rotating rod 103 rotates, the position of each pattern area 1041 on the rotating wheel 104 can be accurately known. This makes the device be able to accurately control the position of the rotating wheel 104 to stop rotating according to the needs, ensures that the specific pattern area 1041 is accurately presented when needed, and meets the diversified display requirements.

[0038] For example, in some game scenarios, a pattern area 1041 with a prize mark can be precisely displayed at a specified position. Alternatively, in some toys, a certain expression pattern or character pattern can be precisely displayed.

[0039] The combination of the position sensor 108 and the blocking piece 1031 adds more interactivity to the rotating device 10. It provides a hardware basis for subsequent combination with an external control system, and allows the rotating wheel 104 to rotate to a specified pattern area 1041 according to the user's operation instructions. For example, in a prize drawing activity, the user presses a button, and the device controls the rotating wheel 104 to stop at the corresponding winning pattern area 1041 according to the preset rules, thereby increasing the user's sense of participation and interest

[0040] In an embodiment, the position sensor 108 is an optical sensor.

[0041] Even if the size of the blocking piece 1031 is small or the rotation speed changes slightly, the optical sensor can clearly detect it. This ability to recognize slight changes allows the rotating device 10 to adapt to different working conditions and design requirements, and to operate stably and accurately whether it is rotating at high speed or low speed.

[0042] Correspondingly, as shown in Figure 5 The present application also provides a display device 1, which can include the rotating device 10, the body 11, and the observation window 12 of any embodiment of the present application.

[0043] When the blocking plate 1052 is in contact with the limiting block 1021, the cap 105 corresponds to the observation window 12.

[0044] Through the above scheme, a special observation position is defined to provide the best viewing position for the user. It can be understood that, since the observation window 12 corresponds to the cap 105 when the limit is reached, the user can be shown the hidden pattern when the motor 106 reverses.

[0045] For ease of understanding, reference can be made to Figure 6 from the perspective A in the figure. The first drawing in the figure is the assumed starting position, and the motor 106 rotates counterclockwise, and the rotating rod 103 simultaneously drives the cap 105 and the rotating wheel 104 to rotate. When it rotates to the position in the second drawing, the blocking plate 1052 is in contact with the limiting block 1021, so the cap 105 stops, and the rotating rod 103 can continue to drive the rotating wheel 104 to rotate, so that the hidden pattern area 1041 can be exposed. At this time, the motor 106 rotates clockwise (i.e., reverses), and the reverse does not have a limiting block 1021, so the rotating rod 103 can simultaneously drive the rotating wheel 104 and the cap 105 to rotate, so that the exposed pattern area 1041 can be displayed to the user through the observation window 12, achieving a sudden change or a face-changing effect.

[0046] In an embodiment, the display device 1 further comprises a controller, the controller being in communication connection with the position sensor 108 and the motor 106 respectively; and a power supply, the power supply being in electrical connection with the controller, the position sensor 108 and the motor 106 respectively.

[0047] In an embodiment, the display device 1 further comprises a switch, the switch being used to start or stop the motor 106.

[0048] It can be understood that, since the display device 1 in the present application contains all the technical features of the rotating device 10, the embodiments and advantages of the rotating device 10 in the present application are applicable to the display device 1 in the present application, and the present application will not be repeated here.

[0049] Compared with the prior art, the rotating device 10 and the display device 1 in the embodiments of the present application have the following advantages:

[0050] The rotating device 10 and the display device 1 in the embodiments of the present application form a device that can rely on friction for synchronous movement by means of the rotating wheel 104 and the cap 105. When the motor 106 drives the rotating rod 103, the part of the rotating wheel 104 blocked by the cap 105 is invisible, thus having a certain unpredictability. When the baffle 1052 on the cap 105 hits the limiting block 1021 fixed on the support, the friction between the cap 105 and the rotating rod 103 is not enough to resist the limiting force, so that the rotating wheel 104 can continue to rotate while the cap 105 stops, so that the pattern on the rotating wheel 104 blocked by the cap 105 suddenly appears, achieving the effect of pattern mutation, reducing the predictability, and thus improving the entertainment effect.

[0051] The above is only the preferred embodiment of the present application, and it should be pointed out that, for ordinary skilled persons in the technical field, several improvements and replacements can be made without departing from the technical principles of the present application, and these improvements and replacements should also be regarded as the protection scope of the present application.
