[0037] As Figures 1 to 6The stage lamp with integrated rotating assembly in the embodiment is shown in the structure comprising a bottom case 100, a supporting arm 101, a lamp head 102 for projecting light beam, and a rotating assembly. The lamp head 102 is rotatably connected to the supporting arm 101 through the rotating assembly. The rotating assembly comprises a rotating shaft sleeve 1 and a pivot shaft 2 which are pivotally connected to each other. The lamp head 102 is rotatably connected to the supporting arm 101 through the mutual pivoting of the rotating shaft sleeve 1 and the pivot shaft 2. In addition, the rotating shaft sleeve 1 or the pivot shaft 2 is integrally formed on the lamp head 102 close to one side of the supporting arm 101. Correspondingly, the pivot shaft 2 or the rotating shaft sleeve 1 is fixedly connected to the supporting arm 101. However, specifically, in the drawings of the embodiment, only the pivot shaft 2 integrally formed on the lamp head 102 and the rotating shaft sleeve 1 fixedly connected to the supporting arm 101 are described as one of the embodiments.

[0038] It can be understood that the stage lamp structure of the embodiment is designed to integrally form the pivot shaft 2 of the rotating assembly on the lamp head 102 of the stage lamp. Compared with the screw connection, the integrally formed pivot shaft 2 on the lamp head 102 of the stage lamp helps to improve the assembly accuracy and structural stability of the pivot part of the stage lamp, and reduces the steps of screw fixing and separate assembly of the shaft assembly, thereby controlling the assembly error and looseness of the stage lamp from the source. The integrated pivot design can eliminate the separate assembly steps for the pivot part, simplify the manufacturing and assembly process, improve the production and assembly efficiency, and reduce the overall cost. The integrally formed structure can better maintain the close fit of the rotating assembly of the pivot part of the stage lamp head after long-term use, reduce the looseness of the fastener caused by vibration, thermal expansion and contraction, etc., and improve the rotation accuracy and service life of the lamp head or support arm. That is, since the pivot shaft 2 is directly formed on the lamp head 102, the problems of shaft center deviation and inconsistent screw fastening caused by the need for multiple screws to position the traditional split shaft are avoided. From a technical logic point of view, the use of an integrated structure can achieve screwless assembly, thereby eliminating multi-point tolerance, significantly reducing the coaxiality and yaw of the pivot part of the lamp head, and ultimately achieving high-precision rotation positioning of the lamp head, reducing the assembly error of the pivot part of the lamp head and improving the positioning accuracy. In addition, it can avoid the attenuation of rotation accuracy caused by screw loosening. During long-term use, the loosening of the fastener caused by vibration, heat dissipation and environmental factors is no longer a major concern. From a technical logic point of view, the use of an integrated design can achieve traditional screwless connection, thereby achieving a more stable lamp head rotation structure, and maintaining a higher level of rotation accuracy of the lamp head in the long term. In addition, since the rotating assembly of the pivot part of the stage lamp head does not need to be frequently disassembled, the rotating friction pair operates in a fixed and accurate shaft position, and the structural fatigue and wear are effectively controlled, thereby effectively reducing the failure rate. When the integrated structure is combined with the motor drive, the assembly gap is smaller, the smoothness of the lamp head pitching or horizontal rotation is improved, and the shaking and drifting phenomena during long-distance projection are suppressed. From a technical logic point of view, the assembly accuracy of the pivot part can effectively reduce the looseness of the pivot part of the lamp head, so that the rotation of the lamp head is more stable, thereby improving the stability of optical projection, and the rotation process of the stage lamp head is more stable and the spot projection accuracy is higher.

[0039] In one embodiment, the lamp head 102 is provided with a support side plate 3 close to one side of the support arm 101, the pivot shaft 2 is integrally formed with the support side plate 3, that is, the pivot shaft 2 is integrally formed on the support side plate 3, and the rotating shaft sleeve 1 is mounted on the support arm 101. After the pivot shaft 2 and the rotating shaft sleeve 1 are pivotally connected, the lamp head 102 can rotate on the support arm 101. It can be understood that the pivot shaft 2 is fixed on the support side plate 3 in the lamp head 102 by integral molding, avoiding the complex assembly of traditional connection by screws or separate parts. In the working process, the support side plate 3 bears part of the weight of the lamp head 102 and the inertia force during rotation, and is pivotally connected with the rotating shaft sleeve 1 on the support arm 101 through the pivot shaft 2. When the stage lamp rotates, the support side plate 3 fixed in the lamp head 102 serves as an intermediate force-bearing part between the lamp head 102 and the pivot assembly, which can ensure smooth movement and high precision between the pivot shaft 2 and the support arm 101. In summary, by integrally forming the pivot shaft or the rotating shaft sleeve with the support side plate 3 in the lamp head, the dimensional accumulation error caused by the split structure of the screw assembly can be reduced, the stability and precision of the stage lamp rotating assembly during long-term use are improved, and the stage lamp manufacturing and installation process is simplified, reducing production cost.

[0040] Specifically, in the present embodiment, the number of support side plates 3 is two, the support arm 101 is in U-shaped structure, the lamp head 102 is pivotally connected to the inner side of the support arm 101 through the rotating assembly, and the number of rotating assemblies is correspondingly set to two. The two support side plates 3 are respectively arranged on the left and right sides of the lamp head 102, and the left and right sides of the lamp head 102 are respectively connected to the rotating shaft sleeve 1 in the support arm 101 through the pivot shaft 2, so that the left and right sides of the lamp head can be supported by the support arm 101, and the structure is more stable.

[0041] In one embodiment, the lamp head 102 is provided with a mounting bracket 4 for pivoting with the support arm 101, and the support side plate 3 is fixedly connected to the mounting bracket 4, and the support side plate 3 is part of the mounting bracket 4. It can be understood that the mounting bracket 4 plays a role of bearing and positioning, ensuring that the support side plate 3 can obtain an accurate and firm mounting position in the lamp head 102. After the support side plate 3 is fixed by the mounting bracket 4, it becomes an integral part of the support pivot shaft 2, providing accurate support for the rotation of the lamp head 102. In the working process, the inertia load or external force during rotation of the lamp head is transmitted to the support side plate 3 through the pivot shaft 2, and finally transmitted to the internal structure of the lamp head 102 by the mounting bracket 4 and dispersed, which can ensure that the force distribution of the lamp head during rotation is more uniform, reducing local stress concentration or vibration.

[0042] Optionally, the pivot shaft 2 and the support side plate 3 are formed by die casting or pressure casting, and in this embodiment, the pivot shaft 2 and the support side plate 3 are formed by die casting or pressure casting. It can be understood that the two processes avoid the separate manufacturing of the support side plate 3 and the pivot shaft 2, but achieve integration through the same process, thereby achieving higher consistency in size, tolerance and surface treatment. After integrated molding, the pivot shaft 2 provided by the support side plate 3 does not need to be additionally assembled and fastened during actual assembly, thereby greatly reducing assembly errors and potential loosening risks. The integrated die casting / pressure casting structure not only reduces the number of parts and the use of connecting fasteners, but also ensures the surface quality and dimensional accuracy of each part through a precision mold, thereby significantly improving the long-term stability and reliability of the stage light in the rotating function.

[0043] Preferably, a plurality of effect modules for intercepting light beams and generating specific light effects are installed in the lamp head 102, and the mounting bracket 4 is a U-shaped structure, and the effect modules are inserted into the inner side of the mounting bracket.

[0044] In one embodiment, the rotating shaft sleeve 1, the pivot shaft 2, and the support side plate 3 are made of aluminum alloy, zinc alloy, or magnesium-aluminum alloy. Such alloy materials have high mechanical strength, good corrosion resistance, and relatively light weight, meeting the durability requirements of the stage light for frequent rotation. When the stage light is working, the lamp head needs to be rotated at different angles. The above-mentioned materials have good performance in terms of impact load and thermal influence during rotation, and at the same time, the weight of the entire lamp head is reduced, facilitating maintenance and operation.

[0045] In one embodiment, the rotating assembly further includes a rotating bearing 5, which is interposed between the pivot shaft 2 and the rotating shaft sleeve 1. The outer periphery of the pivot shaft 2 is connected to the inner ring of the rotating bearing 5, and the inner periphery of the rotating shaft sleeve 1 is connected to the outer ring of the rotating bearing 5. It can be understood that the inner ring of the rotating bearing 5 is tightly fitted with the pivot shaft 2, and the outer ring is tightly fitted with the rotating shaft sleeve 1, which ensures that the bearing can bring low friction and high precision relative movement when the lamp head rotates. When the driving assembly drives the pivot shaft 2 to rotate, the rotating bearing 5 reduces the frictional resistance through its rolling or sliding elements, so that the lamp head can rotate smoothly and at high speed. The bearing also shares part of the load caused by the weight of the lamp head and external impact, reducing wear and heat caused by direct contact between the pivot shaft and the shaft sleeve, solving the problem of easy wear of the rotating assembly, making the rotation smoother and prolonging the service life of the entire machine. It can also prevent the shaft sleeve from loosening or the precision from decreasing due to long-term rotation, thereby improving the overall stability and reliability of the stage light.

[0046] In one embodiment, the pivot shaft 2 is drivingly connected with a driving assembly, which drives the lamp head 102 to rotate around the support arm 101 by driving the pivot shaft 2 to rotate around the rotating sleeve 1, i.e. the driving assembly drives the pivot shaft 2 and the lamp head 102 to rotate together. The driving assembly can adopt various driving structures, such as gear set transmission structure, worm gear transmission structure, etc. Specifically, the driving assembly of the present embodiment includes a motor 6, a driving wheel 7, a rotating wheel 8, and an annular transmission belt 9. The motor 6 is responsible for providing driving force. The driving wheel 7 is coaxially connected to the output shaft of the motor 6. The rotating wheel 8 is coaxially fixedly connected to the pivot shaft 2. The two ends of the annular transmission belt 9 are wound around the driving wheel 7 and the rotating wheel 8, respectively, i.e. the annular transmission belt 9 is bridged between the driving wheel 7 and the rotating wheel 8 to form a closed transmission loop. When the motor 6 works, the output shaft of the motor 6 drives the driving wheel 7 to rotate, and the annular transmission belt 9 transmits the rotating force to the rotating wheel 8, so that the pivot shaft 2 follows the rotation, i.e. the transmission is performed in the order of “motor—driving wheel—transmission belt—rotating wheel—pivot shaft—lamp head”, and a complete rotating driving link is integrated. The annular transmission belt 9 is made of high-wear-resistant and low-noise material (such as rubber or polyurethane), which can maintain stable transmission during work. By adopting the motor 6 and belt driving mode, stable driving and high-efficiency transmission of the pivot shaft 2 are obtained, and noise and transmission loss caused by gear meshing or other complex mechanisms are reduced.

[0047] Optionally, in the present embodiment, the diameter of the pivot shaft 2 is 30-50 mm. The range of 30-50 mm is a relatively optimal design for different specifications of lamp heads considering the common load, rotating torque, and space constraints of stage lamp heads, i.e. the pivot shaft 2 with this size specification can improve the universality and adaptability of the pivot shaft 2, facilitate the unified production of the same stage lamp series or different power lamp types, easily meet the needs of industrial standardized production, and shorten the research and development cycle.

[0048] In one embodiment, preferably, along the light emitting direction of the lamp head 102, the pivot shaft 2 is arranged closer to the light emitting port of the lamp head 102 than the center of gravity of the lamp head 102. It can be understood that since the stage lamp is often integrated with light sources, effect modules, and heat dissipation devices inside the lamp head 102, the center of gravity is not necessarily at the geometric center. By arranging the pivot shaft 2 away from the center of gravity of the lamp head, the lamp head can be naturally downward or maintained in a safe position when powered off or not in use, i.e. the stage lamp can automatically return to a safe orientation (such as the lamp head downward) in the unpowered or accidental power-off state, while maintaining better dynamic balance during work, which is beneficial to subsequent maintenance operations and simplifies the need for resetting the initial position of the lamp head.

[0049] Finally, it should be noted that: the above examples are used to illustrate the technical solutions of the present application, but not limited to; although the present application is described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still be modified to the technical solutions recorded in the foregoing examples, or part of the technical features are replaced; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
