Description

Technical Field

[0001] The utility model relates to a rotating device, in particular to a miniature rotating base. Background Art

[0002] Ornaments are widely used in daily life. To enhance their aesthetics and user experience, manufacturers often install LED lights on them. In the prior art, ornaments can be categorized as either static or moving. While all components of static ornaments are stationary, at least a portion of a moving ornament can move. Whether installing LED lights or other decorative elements to enhance aesthetics or user experience on static or moving ornaments, they are often limited to static components.

[0003] LED lights or other decorations that require electricity cannot be installed on the moving part, nor can the user have a better experience. In order to solve the above technical problems, the applicant applied for a utility model patent on August 17, 2024. The name of the utility model patent is Motor Chamber, and the application number is 2024219957432. Through the motor chamber of the ornament, LED lights or other decorations that require electricity can be set on the rotating part and rotate with the rotating part, which can well solve the above technical problems.

[0004] The original motor compartment uses a "conductive elastic part", that is, a spring, to achieve the effect of "when the conductive ring rotates with the rotating part, the conductive elastic part is always in contact with the conductive ring". The applicant found in subsequent production that although the above-mentioned motor compartment technical solution can solve the problems existing in the existing technology, this connection method has certain defects. The spring is located on one side of the conductive ring and the rotating part. The spring will always exert a lateral force on the conductive ring and the rotating part. Since the rotating part is a vertical axial component, the rotating part is prone to bending during long-term use (that is, the rotating part will not be completely vertical). Once the LED lamp or other decorations to be powered on are long, the bending is more obvious. Therefore, in order to solve the above problems, the applicant has improved and designed the technical solution for the above problems. It is necessary to protect the new technical solution through corresponding applications. Utility Model Content

[0006] According to one aspect of the utility model, a miniature rotating base is provided, including a base body, a rotating cover, a motor, a transmission mechanism, a fixed ring and a moving ring. The rotating cover is arranged on the base body, and the motor and the transmission mechanism are both arranged on the base body. The motor can drive the rotating cover to rotate through the transmission mechanism. The fixed ring is arranged on the base body, and the moving ring is connected to the rotating cover. The rotating cover can drive the moving ring to rotate synchronously. The moving ring can always form an electrical connection with the fixed ring during the rotation process, and the moving ring can be electrically connected to an LED lamp or other decorations that need to be powered.

[0007] In some embodiments, a fixing plate is provided on the base body, and there are two fixing rings, namely an inner fixing ring and an outer fixing ring.

[0013] In the present invention, after the motor is started, the motor can drive the transmission mechanism to rotate, and the transmission mechanism can drive the rotating cover to rotate. Since a moving ring is provided on the rotating cover, when the moving ring rotates with the rotating cover, the moving ring can also always be electrically connected to the fixed ring. The fixed ring can be electrically connected to the power supply through a wire, and the moving ring is electrically connected to the LED lamp or other decorations to be powered on. The LED lamp or other decorations to be powered on will rotate with the moving ring. Therefore, the LED lamp or other decorations to be powered on can always be in an on state, which can solve the problem that the LED lamp or other decorations to be powered on cannot be installed on the rotating parts, so that users have a better usage experience.

[0014] In addition, compared with the utility model named Motor Chamber applied by the applicant on August 17, 2024, the motion ring of the utility model will not exert lateral force on the output shaft of the rotating cover and the transmission mechanism, so that the LED lamp or other decorations that need to be powered on are always in a vertical state.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] Figures 1 to 6 The structure of a micro rotating base according to one embodiment of the present invention is schematically shown.

[0025] like Figures 1 to 6 As shown, a miniature rotating base includes a base body 1, a rotating cover 2, a motor 3, a transmission mechanism 4, a fixed ring and a moving ring.

[0026] like Figure 1 As shown, the rotating cover 2 can be mounted on the base 1 and can rotate relative to the base 1. The motor 3 and the transmission mechanism 4 can be mounted on the base 1. After the motor 3 is started, the motor 3 can drive the rotating cover 2 to rotate via the transmission mechanism 4. The fixed ring can be mounted on the base 1, and the moving ring can be mounted on the rotating cover 2. The moving ring can rotate synchronously with the rotating cover 2. The moving ring can always be electrically connected to the fixed ring during rotation. The fixed ring can be connected to a power source via a wire, and the moving ring can be electrically connected to an LED lamp or other decoration that requires power. Therefore, when power is applied, the LED lamp or other decoration that requires power can remain powered during rotation.

[0027] In this embodiment, if Figure 2 As shown, a fixing plate 11 can be installed on the base 1, and there are two fixing rings, namely an inner fixing ring 5 and an outer fixing ring 6. The inner fixing ring 5 can be set in the inner ring of the outer fixing ring 6, and the inner fixing ring 5 and the outer fixing ring 6 will not have contact. Both fixing rings are fixed to the upper end surface of the fixing plate 11. In addition, Figure 5As can be seen, the two fixed rings are provided with fixing feet 561, which can be fixed to the fixed plate 11 via the fixing feet 561. The fixing feet 561 extend downward and can be electrically connected to the power supply via wires. Therefore, the two fixed rings are fixedly mounted on the base 1 via the fixed plate 11. This embodiment also has two moving rings, namely an inner moving ring 7 and an outer moving ring 8. At least a portion of the lower end surface of the inner moving ring 7 is always in contact with the inner fixed ring 5, and at least a portion of the lower end surface of the outer moving ring 8 is always in contact with the outer fixed ring 6. Therefore, when the inner moving ring 7 and the outer moving ring 8 rotate, the inner moving ring 7 can always form an electrical connection with the inner fixed ring 5, and the outer moving ring 8 can always form an electrical connection with the outer fixed ring 6.

[0028] like Figure 5 and Figure 6 As shown, the lower end surfaces of the inner moving ring 7 and the outer moving ring 8 can be integrally formed with contact pins 9, each with a hemispherical contact portion. The inner moving ring 7 contacts the inner fixed ring 5 via the hemispherical contact portion, and the outer moving ring 8 contacts the outer fixed ring 6 via the hemispherical contact portion. The provision of the hemispherical contact portion can reduce the friction experienced by the outer moving ring 8 during rotation, making the rotation process smoother and more fluid.

[0029] like Figure 5 and Figure 6 As shown, both the inner movement ring 7 and the outer movement ring 8 have two contact pins 9, and each of the inner movement ring 7 and the outer movement ring 8 is provided with two protruding pins 10. The protruding pins 10 extend out of the rotating cover 2 and are engaged with the rotating cover 2. Therefore, the inner movement ring 7 can be fixedly connected to the rotating cover 2 via the protruding pins 10, and the outer movement ring 8 can be fixedly connected to the rotating cover 2 via the protruding pins 10.

[0030] like Figure 3 As shown, a plurality of balls 111 (preferably five balls 111 in this embodiment) may be mounted on the upper end surface of the fixed plate 11, and the rotating cover 2 forms a rolling connection with the fixed plate 11 via the balls 111. Therefore, the balls 111 can reduce the friction force on the rotating cover 2 during rotation.

[0031] like Figure 4As shown, the transmission mechanism 4 includes a plurality of coaxial gear components 41 and helical teeth 42. The output end of the motor 3 is coaxially connected to the helical teeth 42. The helical teeth 42 are connected to one of the coaxial gear components 41. The remaining coaxial gear components 41 are connected to each other in sequence. Another coaxial gear component 41 is coaxially connected to the output shaft 411. The cross-section of the upper end of the output shaft 411 is a regular hexagon. A regular hexagonal through hole is provided in the middle position of the rotating cover 2. The upper end of the output shaft 411 can be inserted into the regular hexagonal through hole in the middle of the rotating cover 2. A fixed rod 13 can also be fixedly installed in the regular hexagonal through hole of the rotating cover 2. An LED lamp or other decorations to be powered can be installed on the fixed rod 13 (for example, the wires of the LED lamp or other decorations to be powered can be passed through the fixed rod 13 and electrically connected to the inner moving ring 7 and the outer moving ring 8). The coaxial gear component 41 in this embodiment is two gears, one large and one small. The connection method of the multiple coaxial gear components 41 can be as follows: Figure 4 As shown, a deceleration effect can be achieved by using a plurality of coaxial gear components 41 , so that the rotation of the rotary cover 2 is slowed down.

[0032] like Figure 4 As shown, the base 1 may be mounted with a battery compartment 12 containing a power source (e.g., dry cell batteries). The power source can provide power to the motor of the present invention and the LED light or other powered decorative item. The motor in this embodiment can be connected in series with the LED light or other powered decorative item, or in parallel with the LED light or other powered decorative item.

[0033] In the present invention, after the motor 3 is started, the motor 3 can drive the transmission mechanism 4 to rotate, and the transmission mechanism 4 can drive the rotating cover 2 to rotate. Since the rotating cover 2 is provided with a motion ring, the motion ring rotates with the rotating cover 2 while the motion ring can always be electrically connected to the fixed ring. The motion ring is electrically connected to the LED light or other decorations to be powered, so that the LED light or other decorations to be powered can be always in the on state while rotating together. This can solve the problem in the prior art that the LED light or other decorations to be powered cannot be installed on the rotating parts, allowing users to have a better user experience. In addition, the motion ring of the present invention will not exert lateral force on the output shaft of the rotating cover 2 and the transmission mechanism 4, so that the LED light or other decorations to be powered can always be in a vertical state.

[0034] The present invention is not limited to the above-mentioned optional implementation methods. Anyone can derive various other forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, any technical solution that falls within the scope defined by the claims of the present invention shall fall within the scope of protection of the present invention.
