Description

Technical Field

[0001] This utility model relates to the field of stage lighting technology, and in particular to a stage light with an integrated rotating shaft in the chassis. Background Technology

[0002] In the field of stage lighting equipment, the base housing serves as the carrier for the main control components and also supports the rotation of the lamp head to achieve multi-dimensional movement and dazzling stage effects. Most stage lights use a support arm to drive the lamp head to rotate horizontally around the base housing. However, in the design of the rotational connection between the support arm and the base housing, existing technologies generally suffer from the following major problems:

[0003] Firstly, regarding structural layout and space utilization, the rotation axis of the existing stage lights, as a load-bearing component, is crucial for installation stability. To ensure installation strength, existing designs often employ a sheet metal structure to build a dedicated fixing platform, which supports and secures the rotation axis. This fixing platform is typically mounted on the base plate of the chassis and extends upwards along the chassis's height. This design significantly occupies the internal vertical space of the chassis, dividing it into multiple areas. This increases the difficulty of arranging critical components such as power modules and control circuits, as well as routing cables across these areas, thereby increasing wiring complexity and potential safety hazards.

[0004] Secondly, regarding the reliability of the rotating connection, existing methods for connecting the rotating shaft to the base housing mostly employ a detachable structure, such as fixing the rotating shaft or its support to the housing with bolts. Under long-term dynamic loads from the rotation of the support arm and lamp head, this type of connection is prone to loosening. Once the connection loosens, it will directly lead to a decrease in the rotational accuracy of the support arm, and may even cause shaking and abnormal noise, seriously affecting the stability and reliability of the stage light.

[0005] Furthermore, regarding the waterproof and dustproof performance of the equipment, to meet the waterproof and dustproof requirements of stage equipment used outdoors or in humid environments, gaps inevitably exist at the interface between the existing split-connection rotating shaft and the base chassis, usually requiring the addition of multiple sealing rings. This not only increases the number of parts and assembly steps, but may also cause the waterproof performance to gradually weaken due to the aging of the sealing rings, thereby allowing moisture or dust to enter the chassis and cause internal components to become damp and damaged.

[0006] In summary, how to optimize the internal space layout of the base chassis, simplify the structure and improve manufacturing efficiency, and significantly improve the waterproof and dustproof performance of the equipment while ensuring the strength and load-bearing capacity of the rotating connection has become a key technical challenge that urgently needs to be solved in the current stage lighting structure design.

The pivot shaft, as an integral extension of the top plate of the base housing, provides a stable center of rotation, while the bushing serves as the rotation interface for the support arm. Through this collaborative work, the support arm achieves stable horizontal rotation relative to the base housing.

[0010] According to the present invention, a stage lamp with an integrated rotating shaft is provided in the chassis. The bushing is pivotally connected to the outer periphery of the pivot shaft. The top plate is provided with an annular protrusion for surrounding the bushing on one side near the support arm. A sealing element is provided between the bushing and the annular protrusion.

[0014] The pivot shaft is located within the receiving cavity and extends from the recess of the receiving cavity toward the outside of the top plate;

[0015] The sealing element is a skeleton oil seal, and the opening of the annular protrusion is larger than the opening of the receiving cavity. The second stepped surface formed between the edge of the cavity opening and the inner edge of the bottom of the annular protrusion abuts against the supporting skeleton of the skeleton oil seal.

[0016] According to the present invention, a stage light with an integrated rotating shaft in the chassis has a top plate recessed into the cavity of the bottom chassis on the side near the support arm to form a receiving cavity.

[0017] The pivot shaft is located within the receiving cavity and extends outward from the recess of the receiving cavity toward the top plate.

[0018] According to the present invention, a stage lamp with an integrated rotating shaft in the chassis is provided with a plurality of second reinforcing ribs on the side of the top plate away from the support arm.

[0019] Each of the second reinforcing ribs is connected to the top plate and is disposed along the outer side wall surrounding the receiving cavity.

[0020] According to the present invention, a stage light with an integrated rotating shaft in its chassis has a pivot shaft protruding from the top plate of the bottom chassis by at least 10 mm.

[0021] According to the present invention, a stage light with an integrated rotating shaft is provided in the chassis, wherein an annular transition slope is formed at the connection between the pivot shaft and the top plate.

[0022] According to the present invention, a stage lamp with an integrated rotating shaft in its chassis is provided, wherein at least one bearing is sleeved between the bushing and the pivot shaft.

[0024] According to the present invention, a stage light with an integrated rotating shaft is provided in the chassis, wherein the side plate and the top plate are integrally formed and include at least two opposing first side plates and two opposing second side plates.

[0025] A stage lamp with an integrated rotating shaft in its chassis, according to the present invention, further includes a drive mechanism, the drive mechanism comprising a motor, a drive wheel, a driven wheel, and a transmission belt;

[0026] The motor and the drive wheel are both fixedly mounted on the support arm;

[0027] The driving wheel is fixed to the power output shaft of the motor and is connected to the driven wheel via the transmission belt.

[0028] The driven wheel is fixed to the pivot shaft;

[0029] The motor outputs torque to the pivot shaft via the transmission belt, drive wheel, and driven wheel, which drives the support arm to rotate around the base housing.

[0030] This invention provides a stage lighting solution with an integrated rotating shaft in its chassis. By integrally molding the pivot shaft with the top plate of the base chassis, it effectively eliminates the weaknesses of traditional split connections, improves the connection strength, overall rigidity, and rotational accuracy of the pivot structure, and avoids the risk of loosening or breakage under long-term load. This integrated design eliminates the need for an additional fixed platform, freeing up vertical space inside the base chassis, optimizing the layout of components such as power modules and control circuits, reducing wiring complexity and safety hazards, and improving space utilization. Simultaneously, it reduces the number of parts and assembly steps, simplifies the manufacturing process, directly reduces material, processing, and labor costs, and significantly improves production efficiency. Furthermore, the structure eliminates potential leakage points between the top plate and the rotating shaft, eliminating the need for multiple sealing rings, greatly improving waterproof and dustproof performance, effectively protecting internal precision components, and extending the equipment's service life. In summary, this invention provides a stage lighting solution with a superior structure and more reliable performance, improving the overall reliability of the product. Attached Figure Description

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0045] like Figures 1 to 8 As shown in the figure, this embodiment of a stage light has an integrated rotating shaft in its chassis. This stage light is mainly used in stage performances, studios and other occasions, and achieves a wonderful lighting effect through the multi-dimensional rotation of the lamp head.

[0046] As described in the background section, the installation of the rotating shaft of existing stage lights typically relies on the support of the base plate of the chassis and the construction of a dedicated fixing platform. This not only divides the internal space of the chassis, increases wiring difficulty and safety hazards, but also makes the detachable connection prone to loosening, affecting rotational accuracy and reliability. Furthermore, the waterproof design is relatively complex. This invention aims to solve the above problems by optimizing the connection structure between the chassis and the rotating shaft, thereby improving the internal space layout of the chassis while ensuring connection strength and waterproof performance.

[0047] In one specific embodiment, the stage light includes a lamp head 300 for generating a light beam, a support arm 200 for supporting the rotation of the lamp head 300, and a base housing 100 for supporting the rotation of the support arm 200. The base housing 100 serves as the base and carrier of the entire device's control core, housing electronic components such as power modules and control circuitry. The base housing 100 includes a top plate 101 and a bottom plate 102, which are joined together by means such as bolts, snap-fit ​​connections, or welding to form a cavity for accommodating the internal components. The support arm 200 is horizontally rotatably connected to the base housing 100 via a rotating assembly, allowing the support arm 200 to rotate about an axis perpendicular to the top plate 101.

[0048] The rotating assembly includes a bushing 201 and a pivot shaft 104 that are pivotally connected to each other. The bushing 201 is fixedly mounted on the support arm 200, specifically, the bushing 201 can be fixedly connected to the horizontal frame 202 of the support arm 200. The horizontal frame 202 is a structural component of the support arm 200, used to connect the lamp head 300 and realize the pitch rotation of the lamp head. The pivot shaft 104 is integrally formed on the top plate 101 of the base housing 100, that is, the pivot shaft 104 and the top plate 101 are a single structural component, for example, manufactured by die casting (such as aluminum alloy or magnesium alloy die casting), forging or other metal integral forming processes. This integrated structure, where the pivot shaft 104 and top plate 101 are integrally formed, significantly reduces the number of parts and assembly errors compared to the traditional separate structure where the rotating shaft is mounted on the chassis frame via a base plate. This simplifies the manufacturing and assembly process, thereby effectively reducing production costs. This integrated structure greatly enhances the strength of the pivot shaft 104 connection root, enabling it to better withstand the weight and dynamic rotational loads of the lamp head 300 and support arm 200. It effectively avoids the loosening or breakage problems associated with traditional connection methods, significantly improving the reliability and durability of the equipment. Furthermore, since there is no need for an additional fixed platform inside the bottom chassis 100, the internal cavity becomes more complete and spacious, greatly optimizing the layout and wiring of components such as the power module and control circuits. This not only reduces wiring complexity but also minimizes potential safety hazards. In addition, the one-piece molding eliminates the need for the top plate 101 to have a hole for the rotation axis, fundamentally eliminating potential leakage points common in traditional designs, which significantly improves the waterproof and dustproof performance of the bottom enclosure 100, making it particularly suitable for outdoor and humid environments.

[0049] To further enhance waterproofing, especially in stage lighting models used outdoors or in humid environments, the top plate 101 near the support arm 200 (i.e., the outer surface of the top plate 101) is provided with an annular protrusion 105 for surrounding the bushing 201. Additionally, a seal is included to seal the outer periphery of the bushing 201, which is pivotally connected to the outer periphery of the pivot shaft 104. In this embodiment, the seal is a skeleton oil seal 106. The annular protrusion 105 forms an annular groove or enclosure structure, the inner side of which is used to engage or accommodate the skeleton oil seal 106. The skeleton oil seal 106 is a commonly used sealing element; its lip can tightly fit between the outer surface of the bushing 201 and the inner wall of the annular protrusion 105, effectively preventing moisture, rainwater, and dust from entering the support arm 200 or the base housing 100 through the connection gap between the bushing 201 and the annular protrusion 105, protecting internal precision components. For stage lighting used indoors, this skeleton oil seal 106 may not be required.

[0050] To ensure that the top plate 101 and the annular protrusion 105 have sufficient structural strength to withstand the load from the support arm 200 and the installation force of the skeleton oil seal 106, a number of first reinforcing ribs 107 and second reinforcing ribs 108 are integrally formed on the top plate 101.

[0051] like Figure 3 As shown, each of the first reinforcing ribs 107 is integrally formed on one side of the top plate 101 of the base housing 100 near the support arm 200, and surrounds and connects to the periphery of the annular protrusion 105. Specifically, these first reinforcing ribs 107 extend along the height direction of the annular protrusion 105, connect the planar portion of the top plate 101 with the outer wall of the annular protrusion 105, and are evenly or non-uniformly distributed along the outer periphery of the annular protrusion 105. This design effectively enhances the deformation resistance of the annular protrusion 105.

[0052] like Figure 4 As shown, each of the second reinforcing ribs 108 is integrally formed in the inner cavity of the bottom housing 100, that is, on one side of the top plate 101 located inside the cavity, and is connected around the periphery of the annular protrusion 105 (corresponding to the position of the annular protrusion 105 on the inner side of the top plate). These second reinforcing ribs 108 can be distributed radially or in a grid pattern, further enhancing the overall rigidity and load-bearing capacity of the top plate 101 in the root region of the pivot shaft 104, and preventing the top plate 101 from deforming under high loads.

[0053] To optimize the mounting structure of the pivot shaft 104 and further enhance the connection strength, the top plate 101 has a recessed cavity 109 on the side facing the bottom housing 100 near the support arm 200. The pivot shaft 104 is located within this cavity 109 and extends from the recessed surface (i.e., the bottom of the cavity) of the cavity 109 towards the outside of the top plate 101 (i.e., away from the bottom housing 100). The pivot shaft 104 needs to have a certain length to ensure effective engagement and load-bearing with the bushing 201. If the pivot shaft 104 protrudes directly from the flat surface of the top plate 101, it may result in an excessively large gap between the support arm 200 and the bottom housing 100, affecting the overall aesthetics and structural compactness. By providing the receiving cavity 109, a portion of the pivot shaft 104 can be "embedded" in the thickness of the top plate 101, or in other words, the root of the pivot shaft 104 is situated on a recessed platform. This ensures the effective length of the pivot shaft 104 while appropriately reducing the installation height between the support arm 200 and the base housing 100. Simultaneously, the formation of the receiving cavity 109 effectively creates a reinforced base around the root of the pivot shaft 104, enhancing the connection strength between the top plate 101 and the pivot shaft 104 and making it less prone to breakage.

[0054] In a preferred embodiment, the pivot shaft 104 protrudes from the top plate 101 of the base housing 100 by at least 10 mm. This length ratio ensures sufficient connection length and load-bearing capacity while maintaining structural compactness. Of course, the specific protruding length ratio can be adjusted according to the actual load, bearing specifications, and space requirements.

[0055] The structural optimizations related to the receiving cavity 109 and the skeleton oil seal 106 are as follows: the opening of the annular protrusion 105 (referring to its inner diameter or the diameter of the space formed to receive the oil seal) is larger than the opening of the receiving cavity 109 (referring to the diameter of the receiving cavity itself). Furthermore, the second stepped surface 119 between the edge of the cavity opening of the receiving cavity 109 and the bottom inner edge of the annular protrusion 105 abuts against the supporting skeleton of the skeleton oil seal 106. This means that the skeleton oil seal 106 can be installed within the annular space formed between the top edge of the cavity opening of the receiving cavity 109 and the bottom inner edge of the annular protrusion 105. The second stepped surface 119 located on the bottom side of this annular space provides an axial positioning and support surface for the skeleton oil seal 106, ensuring that the skeleton oil seal 106 is securely installed and provides a good sealing effect.

[0056] To further improve the fatigue and fracture resistance of the connection between the pivot shaft 104 and the top plate 101, an annular transition slope or rounded corner is formed at the connection between the pivot shaft 104 and the top plate 101 (specifically, the concave surface of the receiving cavity 109). This annular slope (or chamfer, R-angle) can effectively disperse stress and avoid stress concentration at the root of the connection, thereby significantly enhancing the reliability of the connection and preventing fracture under high load or long-term vibration.

[0057] Furthermore, the bushing 201 and the pivot shaft 104 are rotatably connected via at least one bearing 110. Typically, two or more angular contact ball bearings or deep groove ball bearings are used to withstand radial and axial loads. The outer ring of the bearing 110 is embedded in a corresponding countersunk hole in the bushing 201 and secured by an appropriate method (such as an interference fit, retaining ring, or gland). The inner ring of the bearing 110 is fitted onto the pivot shaft 104. To precisely position the inner ring of the bearing 110 and transmit axial force, the outer wall of the pivot shaft 104 is formed with a first stepped surface 111 suitable for abutting against the inner ring of the bearing 110. This first stepped surface 111 is a step with an increased diameter, and one end face of the inner ring of the bearing 110 can be pressed against this first stepped surface 111. In this embodiment, two bearings 110 are provided, which are maintained at a certain distance by bearing spacers 117 and are axially secured at the end of the pivot shaft 104 by fasteners such as shaft end retaining rings 116 (such as snap rings) or nuts, ensuring stable operation of the bearing system.

[0058] To construct a robust base chassis 100 frame, the base chassis 100 also includes side panels. These side panels are supported between the top plate 101 and the base plate 102, together forming a cavity. More specifically, the side panels are integrally formed with the top plate 101 and include two opposing first side panels 103 and two opposing second side panels 118. Each first side panel 103 and each second side panel 118 mutually encloses the cavity and is connected to opposite sides of the top plate 101 from different positions. Each first side panel 103 and each second side panel 118 extends downwards from the top plate 101 and is supported between the top plate 101 and the base plate 102, together constituting the frame structure of the base chassis 100. This integrated side panel design, compared to separate side panels connected by screws or other means, provides higher structural rigidity and overall integrity, offering sufficient strength support for the entire stage lighting system.

[0059] As an improvement to enhance user convenience, handles 114 can be provided on both of the one-piece molded first side panels 103. Since the handles 114 need to support the weight of the entire lamp when moving the equipment, placing them on the one-piece molded first side panels 103 ensures that the handles have sufficient support strength and connection stability. At the same time, this design also makes the installation and maintenance of the equipment more convenient.

[0060] The stage light's support arm 200 needs to be driven to rotate by a drive mechanism. This embodiment also includes a drive mechanism. This drive mechanism is typically installed inside the base housing 100 and includes a motor 120, a drive pulley 121, a driven pulley 112, and a transmission belt 113. The motor 120, drive pulley 121, and bushing 201 are all fixedly mounted on the horizontal frame 202 of the support arm 200. The transmission belt 113 (e.g., a synchronous belt) connects the drive pulley and the driven pulley 112. The drive pulley 121 is coaxially sleeved on the power output shaft of the motor 120 and is connected to the driven pulley 112 via the transmission belt 113.

[0061] Driven wheel 112 is coaxially connected to pivot shaft 104, and is fixedly connected to the end of pivot shaft 104 by several locking screws 115. Motor 120, through transmission belt 113, drive wheel 121, and driven wheel 112, outputs torque to pivot shaft 104, driving support arm 200 and bushing 201 to rotate around pivot shaft 104. It can be understood that since pivot shaft 104 is integrally formed with the top plate 101 of base housing 100, and the top plate 101 is fixed, pivot shaft 104 itself is also fixed and cannot rotate. Therefore, driven wheel 112 fixed to pivot shaft 104 is also fixed and does not rotate. When motor 120, located inside support arm 200, starts, it drives drive wheel 121, also located inside support arm 200, to rotate. Drive wheel 121 transmits torque to driven wheel 112 through transmission belt 113. However, since the driven wheel 112 is fixed to the stationary pivot shaft 104, it cannot rotate. Under the torque transmitted by the driving wheel, the transmission belt 113 tends to "walk" relative to the fixed driven wheel 112. This "walking" force, in turn, acts on the entire support arm 200 that carries the motor 120 and the driving wheel 121, thereby driving the support arm 200 (along with the lamp holder 300 on it) to rotate horizontally around the fixed pivot shaft 104. Simply put, the motor 120 and the driving wheel 121, as power sources, are located on the movable support arm 200. The motor 120 drives the driven wheel 112 fixed to the pivot shaft 104. Since the driven wheel 112 cannot move, it in turn drives the entire support arm 200 to rotate.

[0062] Regarding material selection, to achieve lightweight and high strength, the top plate 101 and / or side plate 103 are preferably made of aluminum alloy or magnesium alloy. These materials have good mechanical properties, thermal conductivity, and machinability, making them very suitable for integrally molding complex structural components through methods such as die casting.

[0063] In summary, this embodiment, by integrally molding the pivot shaft 104 with the top plate 101 of the base housing 100, and combining optimized designs such as the annular protrusion 105, reinforcing ribs 107 and 108, the receiving cavity 109, and the annular inclined surface, not only significantly improves the connection strength, rotation accuracy, and waterproof performance of the stage lighting rotating mechanism, but also effectively optimizes the internal space layout of the base housing 100, reduces manufacturing costs and assembly complexity, and provides a technical solution with a better structure and more reliable performance for the field of stage lighting equipment.

[0064] The above description is only a preferred embodiment of the present utility model and is not intended to limit the technical solution of the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
