[0042] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0043] Please refer to Figure 1-7 , in the embodiment of the present utility model, a driving assembly for an LED moving head lamp includes a rotating bracket 2 for the pitching swing of the lamp holder 3; the rotating bracket 2 is arranged in a U shape, and a rotating power supply assembly 6 is cooperatively installed at the bottom of the rotating bracket 2;

[0044] The rotating power supply assembly 6 includes a rotating tube 66 facilitating the passing of wires, and a positive electrode sliding contact pole piece 64 and a negative electrode sliding contact pole piece 65 are fixed on the inner wall of the rotating tube 66;

[0045] The positive electrode sliding contact pole piece 64 and the negative electrode sliding contact pole piece 65 are made of insulating materials, which can be, but are not limited to, ceramics, plastics, etc.

[0046] The purpose of using insulating materials for the positive electrode sliding contact pole piece 64 and the negative electrode sliding contact pole piece 65 is to prevent the rotating tube 66 from being electrified; ensuring the safe use of the equipment.

[0047] The lower ends of the positive sliding contact electrode sheet 64 and the negative sliding contact electrode sheet 65 are fixed with metal ball heads; the inner sides of the two metal ball heads are respectively connected with the positive line and the negative line for controlling the rotating motor 91;

[0048] The metal ball heads at the lower ends of the positive electrode sliding contact plate 64 and the negative electrode sliding contact plate 65 are slidingly connected to the metal conductive rings arranged in the positive electrode slide 62 and the negative electrode slide 63 .

[0049] The metal ball head contacts the metal conductive rings in the positive slide 62 and the negative slide 63 to achieve rotational movement while ensuring normal power supply, prevent the wire from twisting, and ensure the free rotation of the bottom shell 1 and the rotating bracket 2.

[0050] In this embodiment, the metal conductive ring is arranged in a ring shape, and its longitudinal section is arranged in a C shape; the positive electrode slide 62 and the negative electrode slide 63 are opened inside the power supply base 61; the power supply base 61 is fixed on the inner side of the internal bracket 4.

[0051] Specifically, the upper end of the rotating tube 66 is fixed to the bottom of the rotating bracket 2 via a flange, and the middle position of the rotating tube 66 is rotatably connected to the upper end of the bottom shell 1 via a bearing.

[0052] A driven gear 67 is also mounted on the outer side of the lower end of the rotating tube 66 , and the driven gear 67 is connected to a driving gear 69 mounted on the driving motor 610 through a toothed belt 68 .

[0053] By adopting the above technical solution, when in use, the driving motor 610 drives the rotating tube 66 installed at the bottom of the rotating bracket 2 to rotate with the cooperation of the driving gear 69, the toothed belt 68 and the driven gear 67. While rotating, the positive sliding contact electrode 64 and the negative sliding contact electrode 65 rotate in the positive slide 62 and the negative slide 63 respectively. Since the metal conductive circles in the positive slide 62 and the negative slide 63 are electrically connected to the power module 13 and the controller 5 respectively through wires, the metal ball head can be charged and transmitted to the driving motor 610 and the rotating motor 91 through the wires. When the rotating bracket 2 rotates, the positions of the wires and the driving motor 610 and the rotating motor 91 can be ensured to remain relatively unchanged, so that the rotating bracket 2 can be flexibly and freely rotated without twisting the wires.

[0054] In this embodiment, protruding shafts are fixed on both sides of the lamp holder 3, and the protruding shafts are rotatably connected to the rotating bracket 2 through bearings, and are transmission-connected to the lamp holder driving assembly 9;

[0055] The described lamp holder driving assembly 9 includes a second pulley 93 fitted and mounted with the convex shaft; the second pulley 93 is drivingly connected by a belt to a first pulley 92 mounted on the output shaft of a rotary motor 91; the rotary motor 91 is fixed to the inner side of the rotary bracket 2.

[0056] By adopting the above technical solution, the rotary motor 91 realizes the pitching swing of the lamp holder 3 under the cooperation of the first pulley 92, the belt and the second pulley 93, with a simple structure and convenient control.

[0057] In this embodiment, the controller 5 is electrically connected to the power supply module 13, and the controller 5 is also electrically connected to the signal terminal 10; the power supply module 13 is electrically connected to the power switch 11; the power switch 11 is electrically connected to the power socket 12; the signal terminal 10, the power switch 11 and the power socket 12 are embedded on one side of the bottom shell 1.

[0058] By adopting the above technical solution, the power cord is plugged into the power socket 12, the power supply module 13 converts the commercial power into direct current, and controls the actions of the driving motor 610 and the rotary motor 91 through the controller 5.

[0059] In this embodiment, ventilation windows are provided on both sides of the bottom shell 1, and a heat dissipation fan 7 is provided inside the ventilation windows; the heat dissipation fan 7 is electrically connected to the controller 5 and the power supply module 13; a handle 8 is also provided on the side of the bottom shell 1 where the ventilation window is provided.

[0060] The provision of the heat dissipation fan 7 can dissipate heat from the electrical components inside the bottom shell 1 to ensure the normal operation of the device.

[0061] As a further explanation of the above embodiment, the lamp holder 3 is also connected by a rotary connection and power supply method, with the same principle, so it will not be elaborated here.

[0062] The working principle of the present utility model is: when in use, the driving motor 610 drives the rotary tube 66 mounted at the bottom of the rotary bracket 2 to rotate under the cooperation of the driving gear 69, the toothed belt 68 and the driven gear 67. During the rotation, the positive sliding contact pole piece 64 and the negative sliding contact pole piece 65 rotate in the positive sliding track 62 and the negative sliding track 63 respectively. Since the metal conductive rings in the positive sliding track 62 and the negative sliding track 63 are electrically connected to the power supply module 13 and the controller 5 through wires respectively, this can make the metal ball head charged and transmit it to the driving motor 610 and the rotary motor 91 through wires. When the rotary bracket 2 rotates, it can ensure that the positions of the wires relative to the driving motor 610 and the rotary motor 91 remain unchanged, so as to realize the flexible free rotation of the rotary bracket 2 without the occurrence of wire twisting.

[0063] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model.
