Description

Technical Field

[0001] The utility model relates to the technical field of intelligent Rubik's Cube, and more specifically, to a brush piece and an intelligent Rubik's Cube. Background Art

[0002] The smart Rubik's Cube is an educational toy. When existing smart Rubik's Cubes are rotated, the brush piece contacts or disconnects with the sensor at different positions, generating corresponding electrical signals. This allows for rapid mechanical contact and disconnection, thereby improving the response speed of rotation detection. The brush piece's structure is relatively simple, making installation and maintenance easier. However, it still has drawbacks, such as unstable contact between the brush piece and the sensor, which can lead to signal loss or detection errors. In light of this, we propose a brush piece and a smart Rubik's Cube. Utility Model Content

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art, meet practical needs, and provide a brush and an intelligent Rubik's Cube to solve the technical problem that the contact between the current brush and the sensor is not stable enough.

The lifting pieces are curved structures, and an external protrusion is provided on the lifting piece. The outer periphery of the external protrusion is provided with a warping portion integrally connected to the brush base, and the warping portion and the lifting piece have different lifting angles with the plane of the brush base as the base point.

[0005] Preferably, an extension portion is provided on one side of the tilting portion, a splitting cavity for splitting the tilting portion is opened on one side of the tilting portion, and a convex cone is provided at the center position of one end of the splitting cavity.

[0006] Preferably, the convex cone and the outer protrusion are both made of conductive materials.

[0007] Preferably, the conductive material is silver-plated copper wire.

[0008] Preferably, the brush plate base, the lifting plate, the outer protrusion and the raised portion are integrally formed as a whole.

[0009] Preferably, when the magic cube rotates, it contacts the corresponding detection sensor to realize the transmission of the rotation signal.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. The utility model sets brush points on the surface of the base. The brush points are made of conductive material to ensure conductivity and durability. The brush piece is formed in one piece: the conductive material is processed into the designed shape by machinery and equipment, and does not require secondary processing, achieving the effect of convenient production and processing, and solving the problem of convenient brush manufacturing.

[0012] 2. The utility model also adopts a two-stage lifting structure of the brush point. The length, width and angle of the brush point are precisely designed, which can reduce friction loss while maintaining appropriate contact force. When the Rubik's Cube rotates, it contacts the corresponding detection sensor to realize the transmission structure of the rotation signal, and achieves a stable contact effect between the brush point and the sensor, further solving the problem of unstable contact between the brush piece and the sensor.

[0015] like Figure 1 As shown, the utility model relates to a brush and an intelligent Rubik's Cube, comprising a brush substrate 1, a semicircular cavity 2, a lifting piece 3, an outer protrusion 4, a tilting portion 5, a split cavity 6, and a convex cone 7. The semicircular cavity 2 is arranged on one side of the brush substrate 1, and two holes are arranged on the other side of the brush substrate 1. The two holes can be connected to external devices. The two ends of the brush substrate 1 close to the semicircular cavity 2 are fixed with two lifting pieces 3. The lifting piece 3 is a curved structure. The end of the lifting piece 3 is an outer protrusion 4. The outer periphery of the outer protrusion 4 is provided with a tilting portion 5 integrally connected to the brush substrate 1. An extended portion is provided on one side of the rising portion 5, and a splitting cavity 6 for splitting the extended portion is opened on one side. A convex cone 7 is provided at the center position of one end of the splitting cavity 6. The rising portion 5 and the lifting piece 3 have different lifting angles with the plane of the brush sheet substrate 1 as the base point, forming a two-stage lifting structure. The rising portion 5 and the lifting piece 3 are made of elastic material. The protruding parts on the rising portion 5 and the lifting piece 3 are brush points, namely the convex cone 7 and the outer protrusion 4. The convex cone 7 and the outer protrusion 4 are made of conductive material, and the conductive material is preferably silver-plated copper wire;

[0016] It should be noted that the length, width and angle of the brush points are precisely designed to reduce friction losses while maintaining appropriate contact force;

[0017] Two-stage lifting structure: A two-stage lifting structure is set between the brush base 1 and the brush point. The design of this structure makes the brush contact effective stroke larger and softer, thereby achieving the following effects;

[0018] Increase the softness of the brush: The two-stage lifting structure allows the brush to have a larger deformation space during rotation, thereby improving the softness of the brush, reducing friction and wear caused by excessive hardness, and increasing the effective stroke height of the contact: The two-stage lifting structure also effectively increases the contact stroke between the brush point and the sensor, ensuring stable electrical signal transmission under various operating conditions and avoiding signal loss. The two-stage lifting structure is made of elastic material, which can effectively absorb external force and provide moderate rebound force when the brush contacts the sensor, further improving the service life of the brush.

[0019] In order to facilitate processing and manufacturing, the brush piece is formed in one piece: the conductive material is processed into the designed shape by machinery and equipment, and no secondary processing is required. The one-piece forming can be done by stamping or casting.

[0020] The brush is applied to the smart Rubik's Cube. The brush is installed in the smart Rubik's Cube. When the smart Rubik's Cube rotates, the corresponding detection sensor contacts to realize the transmission of the rotation signal.

[0021] The intelligent Rubik's Cube brush provided by this utility model can effectively improve the accuracy and response speed of rotation detection through optimized design, and significantly improve the softness of the brush and the effective stroke height of the contact through the two-stage lifting structure, thereby extending the service life of the brush and improving the user experience.

[0022] The embodiments disclosed in the present invention are preferred embodiments, but are not limited to them. Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
