Description

Technical Field

[0001] This utility model relates to the field of adjustment device technology, and in particular to a multi-degree-of-freedom flexible adjustment device. Background Technology

[0002] Light beams are a crucial component in modern interior design, and one of the most challenging parameters to control during lighting design is the beam angle. Currently, most designers use lighting simulation software to model their ideal beams on computers, but this often falls short of the desired effect. Multiple trials are needed to determine the lighting effect, and the beam angle of spotlights must be repeatedly adjusted.

[0003] As shown in the reference case "A Multi-Angle Beam Adjustment Device" (publication number CN219433183U), a central block is connected to the middle of the base plate. A spherical slot in the central block is used to mount a rotating ball. The rotating ball can rotate at multiple angles and adjust its tilt, thereby adjusting the angle of the spotlight beam at the bottom. Multiple damping strips are installed in the spherical slot through embedded grooves. The damping strips make frictional contact with the rotating ball, allowing the rotating ball to rotate with damping. The adjustment is convenient. When the desired angle is reached, the rotating ball is permanently fixed by a locking screw to prevent the rotating ball from shaking.

[0004] The existing adjustment components have a small contact area between the locking screw and the rotating ball during use, resulting in concentrated force and making them prone to instability. They are also prone to loosening after prolonged use or under stress, affecting the stability of the beam angle. Furthermore, the screw end directly presses against the ball, which can easily cause surface damage and affect the smoothness of subsequent adjustments.

[0005] Therefore, a multi-degree-of-freedom flexible adjustment device is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a multi-degree-of-freedom flexible adjustment device to solve the aforementioned problems. It improves upon the issues of small contact area between the locking screw and the rotating ball, concentrated force leading to unstable fixing, and easy loosening after long-term use or under stress, thus affecting the stability of the beam angle. Furthermore, the direct pressing of the screw end against the ball can easily cause surface damage, affecting the smoothness of subsequent adjustments.

[0007] This utility model achieves the above-mentioned objectives through the following technical solution: a multi-degree-of-freedom flexible adjustment device, comprising: a mounting base, a fixing frame disposed on one side of the mounting base, and a lamp housing disposed inside the fixing frame; an adjustment and positioning mechanism, the adjustment and positioning mechanism for multi-directional flexible and stable adjustment of the lamp being disposed between the fixing frame and the mounting base; wherein, the adjustment and positioning mechanism includes an adjustment ball fixedly mounted on one side of the mounting base, an adjustment component disposed between the adjustment ball and the fixing frame, and a protective component disposed between the fixing frame and the lamp housing. Through the cooperation of the adjustment component and the adjustment ball, the lamp can be flexibly adjusted in multiple directions. When locking the adjustment ball, the locking pressure is evenly distributed by the adjustment component, avoiding problems such as scratches and indentations on the surface of the adjustment ball caused by concentrated force in traditional structures, extending the service life of the adjustment ball, and ensuring the smoothness of subsequent adjustments. The protective component can hide the wiring harness and also protect the wiring harness, preventing the wiring harness from being exposed and affecting the aesthetics.

[0008] Preferably, the adjustment assembly includes a connecting frame rotatably mounted on the surface of the adjustment ball. The outer side of the connecting frame is connected to the fixing frame, and the inner side of the connecting frame is adapted to the surface of the adjustment ball. Movable tubes are fixedly installed on both sides of the connecting frame. Positioning blocks are slidably installed inside the two movable tubes. The adjacent side of the two positioning blocks abuts against the surface of the adjustment ball. During adjustment, the connecting frame rotates and slides on the surface of the adjustment ball to synchronously drive the fixing frame and the lamp to adjust their angles. After adjustment, the two positioning blocks can be synchronously driven to abut against the surface of the adjustment ball and limit their movement, allowing the positioning blocks to fit against the surface of the adjustment ball over a large area, making the locking force more uniform. Through the flexible buffer contact between the positioning blocks and the adjustment ball, the wear and damage to the surface of the ball caused by direct rigid contact are reduced.

[0009] Preferably, the surface of the movable tube is provided with a movable hole, a movable rod is fixedly installed on one side of the positioning block, one end of the movable rod is slidably installed inside the movable hole, and the same bidirectional screw is provided between the two movable rods, with both ends of the bidirectional screw passing through the two movable rods and threadedly connected to the two movable rods. Through the threaded movement of the bidirectional screw and the two movable rods, the synchronous movement and adjustment of the two positioning blocks can be realized. After the adjustment is completed, the two positioning blocks can simultaneously and evenly limit and fix the adjusting ball.

[0010] Preferably, the moving rod is L-shaped, the interior of the adjusting ball is hollow, and a through hole is provided on the surface of the adjusting ball. The L-shaped moving rod can reduce space occupation, thereby moving the positioning block in a small space.

[0011] Preferably, the fixing frame is U-shaped, and the lamp housing is rotatably installed inside the fixing frame. The lamp housing is rotatably connected to the fixing frame through a damping shaft, which can realize the flexible horizontal rotation of the lamp and the multi-directional adjustment of the adjusting ball, so as to make the light illumination angle more varied.

[0012] Preferably, the protective component includes a conductive slip ring rotatably mounted on the surface of the fixed frame. One end of the conductive slip ring is fixedly connected to the connecting frame. The fixed frame can rotate on one side of the conductive slip ring. The conductive slip ring can provide a stable electrical connection during the rotation of the fixed frame, avoiding cable entanglement caused by repeated rotation.

[0013] Preferably, a spotlight is slidably installed inside the lamp housing, and a telescopic sleeve is fixedly installed between the surface of the lamp housing and one side of the fixing frame. The spotlight can slide axially inside the lamp housing to adjust the illumination distance or the focal length of the beam. When the lamp housing is adjusted in angle or slid, the telescopic sleeve can extend and retract synchronously with the displacement of the lamp housing, thereby effectively protecting the internal cables or wire harnesses.

[0014] The beneficial effects of this utility model are:

[0015] 1. By cooperating with the adjustment component and the adjustment ball, the lamp can be flexibly adjusted in multiple directions. When locking the adjustment ball, the adjustment component evenly distributes the locking pressure, avoiding problems such as scratches and indentations on the surface of the adjustment ball caused by concentrated force in traditional structures. This extends the service life of the adjustment ball and ensures smooth subsequent adjustments. The protective component can hide the wiring harness and also protect it, preventing the wiring harness from being exposed and affecting the aesthetics.

When the lamp housing is adjusted in angle or slid, the telescopic sleeve can extend and retract synchronously with the displacement of the lamp housing, thereby effectively protecting the internal cables or wire harnesses.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In practical implementation: such as Figure 1-4 As shown, a multi-degree-of-freedom flexible adjustment device includes: a mounting base 1, a fixing frame 2 on one side of the mounting base 1, and a lamp housing 21 inside the fixing frame 2; an adjustment positioning mechanism 3, which is used to perform multi-directional flexible and stable adjustment of the lamp and is disposed between the fixing frame 2 and the mounting base 1; wherein, the adjustment positioning mechanism 3 includes an adjustment ball 31 fixedly installed on one side of the mounting base 1, an adjustment component 32 is disposed between the adjustment ball 31 and the fixing frame 2, and a protective component 33 is disposed between the fixing frame 2 and the lamp housing 21. Through the cooperation of the adjustment component 32 and the adjustment ball 31, the lamp can be flexibly adjusted in multiple directions. When locking the adjustment ball 31, the locking pressure is evenly distributed by the adjustment component 32, avoiding the problems of scratches and indentations on the surface of the adjustment ball 31 caused by force concentration in traditional structures, extending the service life of the adjustment ball 31, and ensuring the smoothness of subsequent adjustments. The protective component 33 can hide the wire harness and also protect the wire harness, preventing the wire harness from being exposed and affecting the aesthetics.

[0024] The luminaire achieves focused and directional lighting through an internal light source, reflector, and lens system. In conjunction with the adjustment and positioning mechanism 3, the luminaire can be flexibly adjusted in multiple directions and angles. Furthermore, the adjustment component 32 and the protective component 33 do not affect the normal use and operation of the luminaire during use.

[0025] like Figure 2 and Figure 3As shown, the adjustment assembly 32 includes a connecting frame 321 rotatably mounted on the surface of the adjustment ball 31. The outer side of the connecting frame 321 is connected to the fixed frame 2, and the inner side of the connecting frame 321 is adapted to the surface of the adjustment ball 31. Movable tubes 323 are fixedly installed on both sides of the connecting frame 321. Positioning blocks 324 are slidably installed inside the two movable tubes 323. The adjacent sides of the two positioning blocks 324 are pressed against the surface of the adjustment ball 31. One side of the positioning block 324 has an arc surface structure, and its contact surface matches the surface of the adjustment ball 31, forming a spherical fit. It is made of wear-resistant and anti-slip material, possessing good friction performance and elastic buffering capacity. During adjustment, the connecting frame 321 rotates and slides on the surface of the adjustment ball 31, thereby synchronously driving the fixed frame 2 and the lamp to adjust the angle. After adjustment, the two positioning blocks 324 can be synchronously driven to press against the surface of the adjustment ball 31 for limitation, allowing the positioning blocks 324 to fit against the surface of the adjustment ball 31 over a large area, making the locking force more uniform. The overall stability of the fixing frame 2 and lamp housing 21 is significantly improved. The flexible buffer contact between the positioning block 324 and the adjusting ball 31 reduces the wear and damage to the surface of the ball caused by direct rigid contact, effectively protects the integrity of the adjusting ball 31, and ensures the reliability of the long-term operation of the adjustment system. The surface of the movable tube 323 is provided with a moving hole 325. A moving rod 326 is fixedly installed on one side of the positioning block 324. One end of the moving rod 326 is slidably installed inside the moving hole 325. The same bidirectional screw 327 is provided between the two moving rods 326, and both ends of the bidirectional screw 327 pass through the two moving rods 326 and are threadedly connected to the two moving rods 326. Through the threaded movement of the bidirectional screw 327 and the two moving rods 326, the synchronous movement and adjustment of the two positioning blocks 324 are realized. After the adjustment is completed, the two positioning blocks 324 can simultaneously and evenly limit and fix the adjusting ball 31, so that the two positioning blocks 324 generate symmetrical and uniform locking force when locking.

[0026] The moving rod 326 is L-shaped, the inside of the adjusting ball 31 is hollow, and the surface of the adjusting ball 31 has a through hole 322. The L-shaped moving rod 326 can reduce space occupation, thereby moving the positioning block 324 in a small space. The fixed frame 2 is U-shaped, and the lamp housing 21 is rotatably installed inside the fixed frame 2. The lamp housing 21 is rotatably connected to the fixed frame 2 through a damping shaft, which can realize the flexible rotation of the lamp in the horizontal direction. Combined with the multi-directional adjustment of the adjusting ball 31, the light illumination angle is more abundant.

[0027] like Figure 2 and Figure 4As shown, the protective component 33 includes a conductive slip ring 331 rotatably mounted on the surface of the fixed frame 2. One end of the conductive slip ring 331 is fixedly connected to the connecting frame 321. The fixed frame 2 can rotate on one side of the conductive slip ring 331. The conductive slip ring 331 can provide a stable electrical connection during the rotation of the fixed frame 2, avoiding cable entanglement caused by repeated rotation. A spotlight 333 is slidably mounted inside the lamp housing 21. A telescopic sleeve 332 is fixedly mounted between the surface of the lamp housing 21 and one side of the fixed frame 2. The spotlight 333 can slide axially inside the lamp housing 21 to adjust the illumination distance or beam focal length. When the lamp housing 21 is adjusted in angle or slid, the telescopic sleeve 332 can extend and retract synchronously with the displacement of the lamp housing 21, thereby effectively protecting the internal cables or wire harnesses.

[0028] In use, this invention allows the connecting frame 321 to rotate and slide on the surface of the adjusting ball 31 during adjustment, simultaneously driving the fixing frame 2 and the lamp to adjust their angles. The threaded movement of the bidirectional screw 327 and the two moving rods 326 enables the synchronous movement and adjustment of the two positioning blocks 324. After adjustment, the two positioning blocks 324 simultaneously and evenly limit and fix the adjusting ball 31, generating a symmetrical and uniform locking force during locking. The flexible buffer contact between the positioning blocks 324 and the adjusting ball 31 reduces wear and damage to the ball's surface from direct rigid contact, effectively protecting the integrity of the adjusting ball 31 and ensuring the stability of the adjustment system. For long-term operational reliability, the lamp housing 21 is rotatably connected to the mounting bracket 2 via a damping shaft, allowing for flexible horizontal rotation of the lamp. Combined with the multi-directional adjustment of the adjusting ball 31, this results in a wider range of lighting angles. The mounting bracket 2 can rotate on one side of the conductive slip ring 331, which provides a stable electrical connection during the rotation of the mounting bracket 2, preventing cable tangling caused by repeated rotation. The spotlight 333 can slide axially inside the lamp housing 21 to adjust the illumination distance or beam focal length. The telescopic sleeve 332 can extend and retract synchronously with the displacement of the lamp housing 21 when the lamp housing 21 is adjusted in angle or slid, thus effectively protecting the internal cables or wire harnesses.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
