Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of lighting lamps, in particular to a lens swing structure and a lighting down lamp. BACKGROUND

[0002] The lighting down lamp is an indoor lighting device with a built-in lens and a support. The lens is rotationally connected with the support in the down lamp, so that the lens can swing relative to the support, thereby adjusting the projection direction and range of light to meet different lighting needs. When the lens swings, rotational inertia is generated, which causes the lens to deviate when it stops swinging, making it difficult to control the lens swing. Meanwhile, the support and the lens interact, causing the rotational connection part between the lens and the support to wear out easily.

[0003] As disclosed in the comparative document CN201020649525.5, a novel remote control down lamp includes a cylindrical lamp cylinder with a lamp head inside and an open bottom; a first fixed disc is arranged inside the lamp cylinder, the first fixed disc is connected with the lamp head, and the first fixed disc is arranged in the lamp cylinder in a rotatable manner through a fixed shaft; a first motor is arranged on the first fixed disc, an output shaft of the first motor is connected with a transmission mechanism for driving the lamp head to swing in a horizontal plane; the transmission mechanism includes a driving gear, a driven gear and a rolling belt; the first fixed disc is downwardly provided with a first support, and the first support is provided with the driven gear; the output shaft of the first motor is connected with the driving gear, the driving gear drives the driven gear through the rolling belt, and the driven gear is connected with the lamp holder support provided with the lamp head to swing. However, when the lamp holder support rotates, the lamp holder support swings due to inertia, which causes the lamp holder support to deviate in swing angle, thereby causing the lamp holder support and the first support to wear out easily when rotating.

[0028] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0029] like Figures 1 to 4 As shown, it is a lens swing structure 10 according to an embodiment of the present disclosure, including a support assembly 100, a drive assembly 200, a lens assembly 300 and a damping wheel assembly 400. The support assembly 100 includes a support panel 110, a first connecting arm 120 and a second connecting arm 130. The first connecting arm 120 and the second connecting arm 130 are connected to the same side of the support panel 110 and are arranged in parallel and opposite directions.

[0030] Further, the lens assembly 300 includes a lens body 310, a first rotating arm 320, and a second rotating arm 330. The first rotating arm 320 and the second rotating arm 330 are respectively connected to both ends of the lens body 310. The first rotating arm 320 is rotatably connected to the first connecting arm 120, and the second rotating arm 330 is rotatably connected to the second connecting arm 130. The drive assembly 200 is fixedly connected to the first connecting arm 120. The first rotating arm 320 is provided with a driven gear 321, and the output gear of the drive assembly 200 meshes with the driven gear 321. The damping wheel assembly 400 is fixedly connected to the second rotating arm 330. The second connecting arm 130 is provided with a fixed gear 131, and the fixed gear 131 meshes with the damping wheel assembly 400. The damping wheel assembly 400 is used to slow down the rotation of the fixed gear 131.

[0031] In the embodiment, the output end of the driving assembly 200 rotates to drive the driven gear 321 to rotate, so that the first rotating arm 320 further drives the lens body 310 to swing relative to the first connecting arm 120, thereby causing the second rotating arm 330 to rotate with the second connecting arm 130; when the output end of the driving assembly 200 stops rotating, the driven gear 321 stops rotating, so that the first rotating arm 320 stops swinging with the first connecting arm 120, and the damping wheel assembly 400 slows down the rotation of the cogwheel 131, so that the second rotating arm 330 and the second connecting arm 130 stop swinging quickly.

[0032] The lens swing structure 10 and the lighting down lamp described above, the driving assembly 200 can accurately control the rotation of the driven gear 321, thereby achieving accurate adjustment of the swing of the first rotating arm 320 and the lens body 310; when the output end of the driving assembly 200 stops rotating, the driven gear 321 and the first rotating arm 320 stop rotating, and the damping wheel assembly 400 slows down the inertial rotation of the cogwheel 131, so that the lens body 310 of the lens assembly 300 stops swinging stably, thereby making the swing position of the lens body 310 accurate, and the damping wheel assembly 400 reduces the friction and noise during the rotation of the second rotating arm 330 and the second connecting arm 130, thereby reducing the wear between the second rotating arm 330 and the second connecting arm 130.

[0033] As shown in Figure 2 one of the embodiments, the damping wheel assembly 400 includes a damping seat 410, a shaft core 420, and a damping gear 430, the damping seat 410 is fixed to the second rotating arm 330, the shaft core 420 is rotationally connected to the damping seat 410, and the damping gear 430 is connected to the shaft core 420. In the embodiment, the damping seat 410 is fixed on the second rotating arm 330, and the damping seat 410 is filled with silicon-based damping grease, which increases the rotational friction between the shaft core 420 and the damping seat 410. The silicon-based damping grease buffers the rotation of the shaft core 420, so that the damping gear 430 on the shaft core 420 buffers the rotation of the cogwheel 131, thereby causing the second rotating arm 330 and the second connecting arm 130 to stop stably.

[0034] As shown in Figure 2 one of the embodiments, the second rotating arm 330 is provided with a limiting receiving cavity 3301, and the damping seat 410 is adaptively installed in the limiting receiving cavity 3301. In the embodiment, the damping seat 410 is adaptively installed in the limiting receiving cavity 3301, so that the damping seat 410 is more stable, the installation process of the damping seat 410 is simplified, the damping seat 410 is accurately positioned in the limiting receiving cavity 3301, and the tightness of the engagement between the damping gear 430 and the cogwheel 131 is improved.

[0035] As shown in Figure 3As shown in the drawings, in one embodiment, the driving assembly 200 comprises a motor 210, a rotating shaft 220 and a driving gear 230, the motor 210 is fixed to the first connecting arm 120, the rotating shaft 220 is rotatably connected to the motor 210, the driving gear 230 is connected to the rotating shaft 220, and the driving gear 230 is engaged with the driven gear 321. In this embodiment, the motor 210 drives the rotating shaft 220 to rotate, and the driving gear 230 rotates with the rotating shaft 220, so that the driving gear 230 drives the driven gear 321 to rotate, so that the first rotating arm 320 swings relative to the first connecting arm 120. By adjusting the rotating speed of the motor 210, the swinging speed of the first rotating arm 320 can be changed, and by changing the rotating direction of the motor 210, the forward and reverse swinging of the first rotating arm 320 can be realized, thereby realizing the accurate control of the lens body 310 on the first rotating arm 320 and the second rotating arm 330.

[0036] As shown in the drawings, Figure 3 In one embodiment, the support assembly 100 is also provided with a touch power-off piece 140, which is installed on the second connecting arm 130. The touch power-off piece 140 is provided with a touch end 141, and the lens body 310 is provided with a first blocking strip 311 and a second blocking strip 312. The touch end 141 is arranged between the first blocking strip 311 and the second blocking strip 312. The touch power-off piece 140 is electrically connected to the power supply end of the driving assembly 200, and is used to control the driving assembly 200 to stop working. In this embodiment, when the angle of rotation of the lens body 310 is too large, the touch end 141 of the touch power-off piece 140 on the second connecting arm 130 contacts the first blocking strip 311 and the second blocking strip 312, and the touch power-off piece 140 controls the electrically connected driving assembly 200 to stop working, so that the first rotating arm 320 controls the lens body 310 to stop rotating, thereby effectively limiting the rotation angle of the lens body 310 and providing power-off protection, preventing the lens body 310 from being damaged due to the rotation angle being too large.

[0037] As shown in the drawings, Figure 4 In one embodiment, the inner side of the second connecting arm 130 is provided with a limiting piece 132, the second rotating arm 330 is provided with a first blocking groove 3302, and one end of the limiting piece 132 penetrates the first blocking groove 3302. In this embodiment, when the second rotating arm 330 starts to rotate, one end of the limiting piece 132 slides in the first blocking groove 3302. The sliding range of the limiting piece 132 in the groove is limited, so that when the limiting piece 132 contacts the blocking groove, the rotation angle of the second rotating arm 330 is limited, and the second rotating arm 330 is prevented from rotating, thereby further preventing the rotation angle of the lens body 310 on the second rotating arm 330 from being too large.

[0038] As shown in Figure 3 In one embodiment, the driven gear 321 is an intermittent gear structure. In this embodiment, the driven gear 321 of the intermittent gear structure has a limited number of teeth, and when the part of the driving gear 230 engaged with the driven gear 321 exceeds the teeth of the driven gear 321 of the first rotating arm 320, the first rotating arm 320 stops rotating, thereby effectively controlling the rotation range of the first rotating arm 320.

[0039] As shown in Figure 3 In one embodiment, the inner side of the first connecting arm 120 is provided with a second limiting groove 1201, and the driven gear 321 is arranged in the second limiting groove 1201. In this embodiment, the second limiting groove 1201 can limit the rotation angle of the driven gear 321 of the first rotating arm 320, further limiting the activity range of the first rotating arm 320, thereby effectively controlling the swing range of the lens body 310 on the first rotating arm 320.

[0040] As shown in Figure 1 In one embodiment, the lens assembly 300 further comprises a first reinforcing rib 340 and a second reinforcing rib 350, the first reinforcing rib 340 is connected to the first rotating arm 320 and the lens body 310, and the second reinforcing rib 350 is connected to the second rotating arm 330 and the lens body 310. In this embodiment, by arranging the first reinforcing rib 340 and the second reinforcing rib 350, the connection strength between the first rotating arm 320, the lens body 310 and the second rotating arm 330 is increased, so that the lens assembly 300 can remain stable when stressed, reducing the possibility of deformation and vibration.

[0041] The application also provides a lighting downlight, which comprises the lens swing structure 10 in any of the above embodiments, and a receiving groove is arranged in the shell, and the lens swing structure is mounted in the receiving groove. In this embodiment, the lens body 310 of the lighting downlight is smoothly and reliably swung in the shell through the lens swing structure 10, thereby increasing the durability of the lighting downlight.

[0042] Compared with the prior art, the present disclosure has at least the following advantages:

[0043] The lens swing structure 10 and the illumination down lamp described above, the driving assembly 200 can accurately control the rotation of the driven gear 321, thereby realizing the accurate adjustment of the swing of the first rotating arm 320 and the lens body 310, when the output end of the driving assembly 200 stops rotating, the driven gear 321 and the first rotating arm 320 stop rotating, the damping wheel assembly 400 slows down the inertial rotation of the cogged wheel 131, so that the lens body 310 of the lens assembly 300 stops swinging stably, thereby making the swing position of the lens body 310 accurate, the damping wheel assembly 400 reduces the friction and noise in the rotation process of the second rotating arm 330 and the second connecting arm 130, and further reduces the wear between the second rotating arm 330 and the second connecting arm 130.

[0044] The above-described embodiments only express several implementation manners of the present disclosure, and the description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the disclosed patent. It should be noted that, for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure.
