Description

Technical Field

[0001] The utility model relates to the technical field of power mechanisms, and particularly to a driving mechanism. Background Art

[0002] The ring-shaped chandelier with the application number 2020109323850 adopts a conductive slip ring with the application number 2020226091099. The conductive slip ring has the following problems: the stator is sleeved outside the cylinder, the cylinder axially protrudes from the rotor, and the outer surface of the connecting pipe of the driving mechanism is fixed by screws on the side surface of the protruding end of the cylinder. Moreover, a limiting block is arranged in the circumferential direction of the protruding end of the cylinder to limit the axial position of the rotor. The limiting block is also fixed on the protruding end of the cylinder by screws. Whether it is the fixation with the connecting pipe of the driving mechanism or the limitation of the rotor, multiple screws penetrating from the side are required, and it cannot be assembled by equipment. Manual assembly is time-consuming and laborious; the cylinder protrudes outside the rotor, making the thickness of the conductive slip ring too thick, which limits the number of rotating lamps on the ring-shaped chandelier. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a driving mechanism, which adopts a thin conductive slip ring. By arranging a convex block inside the shaft sleeve of the conductive slip ring for positioning connection with the arc-shaped orientation pipe, the shaft sleeve does not need to protrude from the rotor, thereby reducing the space required for the installation of the driving mechanism.

[0004] The technical solution adopted by the utility model to solve the above technical problems is as follows:

[0005] A driving mechanism includes a housing, a power assembly, a wing frame, an arc-shaped orientation pipe, and a conductive slip ring. One end of the arc-shaped orientation pipe is fixedly connected to the inside of the housing, and the other end of the arc-shaped orientation pipe extends out of the housing. The conductive slip ring includes a shaft sleeve, a stator, a rotor, and a housing that are sleeved and installed in sequence from the inside to the outside. A convex block is arranged on the inner wall of the shaft sleeve, a clamping groove is arranged on the outer side wall of the arc-shaped orientation pipe, the conductive slip ring is sleeved on one end of the arc-shaped orientation pipe extending out of the housing, the convex block is clamped in the clamping groove, the wing frame, the housing, and the rotor are fixedly connected, and the power assembly is arranged inside the housing to drive the wing frame to rotate relative to the arc-shaped orientation pipe.

[0006] Preferably, a first notch is formed at one end of the arc-shaped orientation pipe extending out of the housing to form the clamping groove.

[0007] Preferably, the power assembly includes a motor, a driving wheel, and a driven wheel. The driving wheel is connected to the output shaft of the motor, the driven wheel is sleeved outside the arc-shaped orientation pipe, the driven wheel is fixedly connected to the wing frame, and the driving wheel and the driven wheel are meshed or connected by a belt.

[0008] Preferably, a first bearing is provided between the driven wheel and the arc directional tube.

[0009] Preferably, a first opening is provided on a side of the shell facing the wing frame, and the first opening is enclosed by a side dustproof plate.

[0010] Preferably, a control module is arranged above the power assembly, and a second opening is provided on the top of the shell, and the second opening is sealed by an upper dustproof plate.

[0011] Preferably, a mounting groove is provided in the middle of the wing frame, and the conductive slip ring is completely accommodated in the mounting groove.

[0012] Preferably, a plurality of conductive annular grooves are axially distributed on the outer wall of the stator, and a through hole is provided on the rotor, in which a brush wire is passed. One end of the brush wire passes through the through hole to the inside of the rotor and contacts the bottom of the conductive annular groove.

[0013] Preferably, the housing is provided with a second notch, and the wire connected to the brush wire is led out through the second notch.

[0014] Preferably, the wing frame has a wire accommodating cavity, and the inner side wall of the mounting groove is provided with a through hole communicating with the wire accommodating cavity.

[0015] Compared with the prior art, the advantages of the utility model are:

[0016] 1. By setting the bump inside the conductive slip ring and the slot of the arc directional tube for installation, compared with the traditional multi-screw locking method that requires precise alignment and tightening of multiple screws, the new bump slot design only requires one clamping action, which greatly simplifies the installation process and improves production efficiency. Due to the reduction in the use of screws, the number of parts that need to be inspected and replaced during maintenance is reduced, thereby reducing maintenance costs and workload. The close fit between the bump and the slot provides better structural stability and reduces the risk of equipment failure caused by loose screws.

[0017] 2. By setting the shell to a structure with openings on both the side and the top, the first opening on the side facilitates the installation of drive components such as the motor, and the second opening on the top facilitates the installation and maintenance of the control module.

[0018] 3. By using the conductive slip ring in the present application, the wires led out of the rotor extend through the through hole into the wire accommodating cavity and are connected to the lamp at the outer end of the wing frame. In this way, the wires will not be entangled during the clockwise or counterclockwise rotation of the wing frame, and the electrical connection is stable. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0029] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model.

[0030] Embodiment 1

[0031] A driving mechanism, as shown in combination with Figure 1-8 the figure, includes a housing 1, a power assembly, a wing frame 3, an arc-shaped orientation tube 4, and a conductive slip ring 5. The power assembly is located inside the housing 1 and is used to drive the wing frame 3 located outside the housing 1 to rotate around the arc-shaped orientation tube 4.

[0032] The power assembly includes a motor 21, a driving wheel 22, and a driven wheel 23. The driving wheel 22 is connected to the output shaft of the motor 21. The driven wheel 23 is sleeved outside the arc-shaped orientation tube 4, and the driven wheel 23 is fixedly connected to the wing frame 3. The driving wheel 22 and the driven wheel 23 are meshed or connected by a belt. A first bearing 24 is arranged between the driven wheel 23 and the arc-shaped orientation tube 4 to reduce the friction during the rotation of the driven wheel 23.

[0033] One side of the housing 1 facing the wing frame 3 is provided with a first opening 11, and the opposite side is provided with a first through hole 12. One end of the arc-shaped orientation tube 4 has a flange 41, which is fixedly screwed to the edge of the first through hole 12 on the housing 1, so as to fix the arc-shaped orientation tube 4 to the housing 1. The other end of the arc-shaped orientation tube 4 extends out of the housing 1 through the first opening 11. The power assembly is installed into the housing 1 through the first opening 11 and then sealed by a side dust-proof plate 13. There is a through hole on the side dust-proof plate 13 or an installation space is left between the side dust-proof plate 13 and the housing 1 to facilitate the partial accommodation or passing through of the arc-shaped orientation tube 4 and the driven wheel 23.

[0034] A control module 6 is arranged above the motor 21. Therefore, a second opening 14 is opened at the top of the housing 1, and the second opening 14 is sealed by an upper dust-proof plate 15.

[0035] On one side of the middle of the wing frame 3 far from the housing 1, there is an installation groove 31. The bottom of the installation groove 31 has a second through hole. The conductive slip ring 5 is installed in the installation groove 31. After the arc-shaped orientation tube 4 enters the installation groove 31 through the second through hole, it is connected to the conductive slip ring 5.

[0036] The conductive slip ring 5 includes a bushing 51, a stator 52, a rotor 53, and a housing 54 that are sleeved and installed in sequence from the inside to the outside. The housing 54 is fixedly connected to the rotor 53 and rotates synchronously with the rotor 53.

[0037] At least one convex block 511 is arranged on the inner wall of the bushing 51. One end of the arc-shaped orientation tube 4 extending out of the housing 1 is provided with a first notch to form a clamping groove 42. The conductive slip ring 5 is sleeved outside the arc-shaped orientation tube 4, and the positioning and clamping connection between the convex block 511 and the clamping groove 42 is used to realize the limit installation of the conductive slip ring 5.

[0038] The bushing 51 includes a first end and a second end. In order to make the conductive slip ring 5 thin enough, the second end of the bushing 51 is received in the rotor 53, or the second end of the bushing 51 is flush with the outer end face of the rotor 53, so as to prevent the bushing 51 from protruding from the rotor 53 and increasing the thickness of the conductive slip ring 5. In this embodiment, although the first end of the bushing 51 protrudes from the rotor 53, the first end of the bushing 51 is restricted within the housing 54 or flush with the end face of the housing 54, so the thickness of the conductive slip ring 5 will not be increased either. Those skilled in the art should understand that the first end of the bushing 51 can be completely received within the housing 54, which mainly depends on the structural arrangement of the housing 54.

[0039] A second bearing 56 and a stator 52 are sleeved on the outer side of the bushing 51. A positioning structure 512 extends radially outward from the first end of the bushing 51. A ring-shaped cover plate 55 is fixedly connected to the second end of the bushing 51. The bearing and the stator 52 are axially arranged between the ring-shaped cover plate 55 and the positioning structure 512. The ring-shaped cover plate 55 is coaxially arranged with the bushing 51. The outer diameter of the ring-shaped cover plate 55 is larger than the outer diameter of the second end of the bushing 51. A limiting structure 533 is provided on the inner wall of the rotor 53. The end face of the ring-shaped cover plate 55 away from the bushing 51 abuts against the limiting structure 533.

[0040] In this embodiment, the second bearing 56 is close to the positioning structure 512, and the stator 52 is close to the ring-shaped cover plate 55. The outer diameter of the second bearing 56 is larger than the outer diameter of the stator 52. An annular groove 534 for accommodating the second bearing 56 is provided on the inner side wall of the rotor 53, which restricts the position of the second bearing 56 and can prevent the second bearing 56 from affecting the stator 52.

[0041] A retaining edge extends radially inward from one end of the housing 54. The housing 54 is fixedly screwed to the rotor 53 through the retaining edge. The second end of the bushing 51 is restricted by the limiting structure 533 of the rotor 53, so that the bushing 51 and the stator 52 cannot break away from the rotor 53. The limiting structure 533 can be an annular rib or a plurality of annular blocks arranged at intervals.

[0042] Specifically, a plurality of the above-mentioned bumps 511 are distributed on the inner wall of the bushing 51 along the circumferential direction. The plurality of bumps 511 axially protrude from the bushing 51. The ring-shaped cover plate 55 is sleeved outside the plurality of bumps 511 to restrict the position of the ring-shaped cover plate 55.

[0043] A wire groove 513 is provided on the outer side wall of the bushing 51. A wire hole 551 is provided on the ring-shaped cover plate 55. The wire hole 551 is correspondingly communicated with the wire groove 513. The lead wire of the stator 52 passes through the wire groove 513 and the wire hole 551 and then exits. Specifically, the wire hole 551 is aligned with one of the bumps 511, which is convenient for alignment installation. Those skilled in the art should understand that the wire hole 551 can also be provided on the positioning structure 512. The positioning structure 512 is an annular rib or a plurality of annular blocks arranged at intervals.

[0044] The rotor 53 includes a plurality of arc-shaped docking blocks 531, and the plurality of arc-shaped docking blocks 531 are arranged in a circular ring shape. A positioning component is arranged between two adjacent arc-shaped docking blocks 531. The positioning component includes a positioning block 5311 and a positioning groove 5312. The positioning block 5311 is arranged on one arc-shaped docking block 531, and the positioning groove 5312 is arranged on another adjacent arc-shaped docking block 531.

[0045] A plurality of conductive ring grooves 521 are distributed along the axial direction on the outer side wall of the stator 52. Three lead wires are fixedly installed in the wire grooves 513 of the bushing 51 by interval potting insulation. After the lead wires are led out and pass through the wire holes 551 of the annular cover plate 55, the annular cover plate 55 is fixed to the second end of the bushing 51 by screws, ensuring the axial movement of the bushing 51 and the rotor 53 during installation and transportation, and filling glue into the wire holes 551 to fix the lead wires. At least one arc-shaped docking block 531 is provided with a through hole, and a brush wire 532 is inserted through the through hole. One end of the brush wire 532 passing through the through hole into the interior of the rotor 53 contacts the bottom of the conductive ring groove 521. A plurality of brush wires 532 are arranged on the rotor 53 and inserted through the through holes, and the lead wires are led out and the brush wires 532 and the lead wires are fixed by potting. The housing 54 is provided with a second notch 541, and the lead wires connected to the brush wires 532 are led out through the second notch 541.

[0046] During installation, the arc-shaped orientation tube 4 extends out of the housing 1, and then the wing frame 3 is sleeved on the outer side of the arc-shaped orientation tube 4. The circular orientation tube extends into the installation groove 31. The clamping groove 42 of the circular orientation tube is clamped and matched with the convex block 511 in the bushing 51, so that the bushing 51 cannot rotate relative to the arc-shaped orientation tube 4. The housing 54 is fixedly connected to the installation groove 31 of the wing frame 3 by screws. The wing frame 3, the housing 54 and the rotor 53 are fixedly connected, and the rotor 53 and the wing frame 3 can rotate synchronously and continuously for 360 degrees without winding. The wing frame 3 has a wire accommodating cavity, and a through hole 311 communicating with the wire accommodating cavity is opened on the inner side wall of the installation groove 31.

[0047] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
