Description

Technical Field

[0001] This invention belongs to the technical field of lighting auxiliary devices, specifically referring to a controllable lighting-specific lifting device. Background Technology

[0002] In indoor lighting scenarios, the height of light fixtures (such as chandeliers, exhibition hall display lights, etc.) often needs to be adjusted according to usage requirements.

[0003] Traditional lighting lifters suffer from insufficient lifting control precision, poor braking stability, and easy structural wear, leading to uncontrollable lifting and stopping processes, inability to stop precisely, and short service life. They are ill-suited for scenarios requiring high controllability and reliability (such as high-end exhibition halls and stage lighting). Therefore, there is an urgent need for a controllable lighting lifter that offers strong controllability, stable braking, and a reliable structure. Summary of the Invention

[0004] To address the aforementioned challenges, this invention provides a controllable lighting fixture lifting device that enables precise control of lighting fixture lifting, improves braking stability and structural reliability, and extends the device's service life.

[0005] To achieve the above functions, the technical solution adopted by the present invention is as follows: a controllable lighting fixture lifting device, comprising a first housing and a second housing, the first housing and the second housing being assembled together to form an internal installation space, within which a braking component and a power board component are arranged; a rotating shaft is provided on the inner wall of the second housing, and a pull-coil wheel is fitted on the rotating shaft, rotating coaxially with the rotating shaft; a lifting line is wound on the pull-coil wheel, one end of the lifting line is wound around the outer circumference of the pull-coil wheel, and the other end of the lifting line is used to connect to the lighting fixture to be lifted; the lifting line is retracted and extended by the rotation of the pull-coil wheel; a lifting spring is connected between the pull-coil wheel and the rotating shaft, the lifting spring being a spiral spring structure, one end of the lifting spring being fixedly connected to the rotating shaft, and the other end of the lifting spring being fixedly connected to the pull-coil wheel; the lifting restoring force is provided by the elastic deformation released by its own winding.

[0006] As a preferred embodiment of the present invention, the braking assembly includes a brake pad, a brake pad cover, and a spring disc brake rail. The brake pad is installed on one side of the spring disc brake rail. The brake pad cover is installed on the inner wall of the outer casing by bolts. The brake pad cover covers the outside of the brake pad and provides axial restraint for the brake pad. The spring disc brake rail is configured to cooperate with the brake pad.

[0007] As a preferred embodiment of the present invention, the spring disc brake rail is provided with an arc-shaped toothed groove, and the brake pad is provided with a tooth head that matches the arc-shaped toothed groove, so that the reliability of brake locking is ensured when the two are engaged.

[0008] As a preferred embodiment of the present invention, the power board assembly includes a power board one and a power board two, which are respectively installed inside the housing two to provide power and signal control support for the electronic control execution part of the braking assembly.

[0009] As a preferred embodiment of the present invention, both the first and second outer shells are provided with threaded openings at their bottoms, and the inner sidewalls of the threaded openings are provided with threads. The threaded openings, in conjunction with the external lead screws, provide a fixing effect for the entire assembly.

[0010] Compared with the prior art, the present invention achieves the following beneficial effects by adopting the above structure: 1. Through the coordinated electronic and mechanical control of the power board assembly and the braking assembly, precise braking and stable stopping can be achieved at any position during the raising and lowering of the lamp, meeting the fine adjustment needs of lamp height in different scenarios; 2. The brake pads and spring disc brake rail work together to form a dual guarantee of "mechanical locking and friction braking", which effectively avoids slippage and loss of control during the lifting process and improves braking stability and safety. 3. The lifting spring adopts a spiral structure, which provides uniform elastic restoring force during the release and winding process. Combined with the synchronous winding and unwinding action of the pull wheel, it ensures that the lifting and lowering process of the lamp is smooth and without jerking, thus improving the user experience.

[0013] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0014] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The invention will be further described in detail below with reference to the accompanying drawings.

[0015] like Figures 1-7 As shown, the controllable lighting fixture lifting device provided by the present invention includes a first outer shell 1 and a second outer shell 2, which are assembled together to form an internal installation space. Both the first outer shell 1 and the second outer shell 2 have threaded openings 9 at their bottoms, and the inner walls of the threaded openings 9 are provided with threads. The threaded openings 9, in conjunction with an external lead screw, provide a fixing function for the entire assembly. A braking component 3 and a power board component 4 are arranged within the installation space formed by the assembly of the first outer shell 1 and the second outer shell 2. A rotating shaft 5 is provided on the inner wall of the second outer shell 2, and a [missing information - likely a component or part] is fitted onto the rotating shaft 5. A pull reel 6 rotates coaxially with a rotating shaft 5. A lifting line 7 is wound around the pull reel 6. One end of the lifting line 7 is wrapped around the outer circumference of the pull reel 6, and the other end is used to connect to the lamp to be raised or lowered. The lifting line 7 is raised or lowered by the rotation of the pull reel 6. A lifting spring 8 is connected between the pull reel 6 and the rotating shaft 5. The lifting spring 8 is a spiral spring structure. One end of the lifting spring 8 is fixedly connected to the rotating shaft 5, and the other end of the lifting spring 8 is fixedly connected to the pull reel 6. The lifting and lowering restoring force is provided by the elastic deformation released by its own winding.

[0016] like Figures 1-3 and Figure 6As shown, the braking assembly 3 includes a brake pad 301, a brake pad cover 302, and a spring disc brake rail 303. The brake pad 301 is installed on one side of the spring disc brake rail 303. The brake pad cover 302 is installed on the inner wall of the outer casing 1 by bolts. The brake pad cover 302 covers the outside of the brake pad 301 and forms an axial limit on the brake pad 301. The spring disc brake rail 303 is configured to cooperate with the brake pad 301. The spring disc brake rail 303 is provided with an arc-shaped tooth groove. The brake pad 301 is provided with a tooth head that matches the arc-shaped tooth groove. When the two are engaged, the reliability of the brake lock is ensured.

[0017] like Figures 1-3 and Figure 5 As shown, the power board assembly 4 includes a first power board 401 and a second power board 402. The first power board 401 and the second power board 402 are respectively installed inside the second housing 2 to provide power and signal control support for the electronic control execution part of the braking assembly 3.

[0018] In practical use, the user sends a "descend" signal via remote control. After receiving the signal, the power board 402 disengages from the spring disc brake rail 303. At this time, the weight of the lamp drives the pull wheel 6 to rotate, and the shaft 5 rotates synchronously. The lifting spring 8 is wound up and stores energy, and the lifting line 7 is gradually released from the groove of the pull wheel 6. The lamp descends smoothly until the user triggers a "stop" signal or reaches the lowest limit. The user then sends an "ascend" signal. The power board 401 remains in the retracted state, the lifting spring 8 releases its stored energy, and drives the shaft 5 to rotate counterclockwise. The pull wheel 6 synchronously winds up the lifting line 7, and the lamp rises under the restoring force of the lifting spring 8. If it is necessary to stop midway, a "brake" signal is sent, and the brake pad 301 is pressed against the pull wheel 6. The friction force stops the pull wheel 6 from rotating, and the lamp stops stably.

[0019] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
