Description

TECHNICAL FIELD

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

[0002] The rotating down lamp is a lighting device with adjustable light irradiation angle. One end of the rotating down lamp can be rotated to adjust the light irradiation angle, so as to adjust the direction and range of light according to the needs. The lens of the down lamp is rotatably connected with the down lamp body through a rotating connection assembly. When the rotating connection assembly in the down lamp rotates, due to the influence of the tolerance of the rotating connection assembly of the down lamp, a slight deviation occurs between the rotating connection assemblies. The deviation will cause the surface of the rotating connection assembly to be worn, thereby causing the rotating connection assembly to be easily damaged.

[0003] As disclosed in the comparative file CN202122400291.1, a down lamp for fixing a light-emitting module through a ball assembly includes a face ring assembly and a light-emitting module. The light-emitting module is provided with a ball assembly, and the shell of the face ring assembly is provided with a circular clamping groove one. The ball assembly is buckled with the circular clamping groove one, so that the light-emitting module is rotatably installed on the shell of the face ring assembly. The scheme makes the light-emitting module rotatably installed on the shell of the face ring assembly through the ball assembly and the circular clamping groove one. However, the scheme fails to solve the problem that the light-emitting module and the rotating face ring assembly have a tolerance, which causes a deviation during rotation, thereby causing the light-emitting module and the rotating face ring assembly to be easily damaged.

[0029] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0030] like Figures 1 to 5 As shown, it is a horizontal rotation structure 10 according to an embodiment of the present disclosure, including a housing assembly 100, a sliding connection assembly 200, an elastic abutment assembly 300 and a lens mount assembly 400. The housing assembly 100 includes an upper housing 110 and a lower housing 120. The lower housing 120 is connected to the upper housing 110. The upper housing 110 is used to mount a light source. The lens mount assembly 400 is located below the light source and is used to mount a lens.

[0031] Furthermore, a sliding cavity 101 is formed between the upper housing 110 and the lower housing 120. The sliding connection assembly 200 includes a rotating ring plate 210, ball bearings 220, and a sliding ring 230 installed in the sliding cavity 101. A mounting ring portion 121 protrudes from the lower housing 120. The sliding ring 230 is sleeved on the mounting ring portion 121. The sliding ring 230 is disposed between the rotating ring plate 210 and the lower housing 120. The sliding ring 230 has a circular groove 2301. There are multiple circular grooves 2301 and ball bearings 220. Each ball bearing 220 is installed in a corresponding circular groove 2301. One end of the elastic abutment assembly 300 is fixed to the upper housing 110, and the other end of the elastic abutment assembly 300 elastically abuts against the rotating ring plate 210. The lens mount assembly 400 is connected to the rotating ring plate 210.

[0032] In the embodiment, the sliding ring 230 limits the rolling balls 220 in the circular grooves 2301 during the rotation of the rotating ring plate 210, the rolling balls 220 are used to support the smooth sliding between the rotating ring plate 210 and the lower shell 120, so that the rotating ring plate 210 is freely rotated in the sliding cavity 101, thereby driving the lens seat assembly 400 to rotate; when the rotating ring plate 210 vibrates or shifts up and down during the rotation, the elastic abutting assembly 300 elastically deforms to keep the elastic abutment to the rotating ring plate 210.

[0033] The horizontal rotation structure 10 described above limits the plurality of rolling balls 220 in the corresponding circular grooves 2301 through the sliding ring 230, so that the plurality of rolling balls 220 uniformly support the rotation of the rotating ring plate 210 and the lower shell 120, thereby making the rotating ring plate 210 slide more smoothly on the lower shell 120, and further making the lens seat assembly 400 on the rotating ring plate 210 rotate smoothly; the elastic abutting assembly 300 elastically deforms to keep the elastic abutment to the rotating ring plate 210, so that the rotating ring plate 210 is continuously abutted by the elasticity, thereby keeping the rotating ring plate 210 better stability and continuity during rotation, and further reducing the risk of damage caused by vibration or shift between the rotating ring plate 210 and the lower shell 120.

[0034] As shown in Figure 1 and Figure 2 In one embodiment, the elastic abutting assembly 300 includes a mounting shell 310, a spring 320 and a ball 330, the mounting shell 310 is connected to the upper shell 110, the mounting shell 310 is provided with a containing cavity 3101, the spring 320 and the ball 330 are installed in the containing cavity 3101, the two ends of the spring 320 are respectively abutted to the mounting shell 310 and the ball 330, and the ball 330 is abutted to the rotating ring plate 210. In the embodiment, the containing cavity 3101 provided by the mounting shell 310 provides the installation space of the spring 320 and the ball 330, when the rotating ring plate 210 vibrates or shifts during the rotation, the spring 320 can absorb the impact by its elastic deformation, and the ball 330 makes point contact with the rotating ring plate 210 through the surface, which reduces the friction resistance between the ball 330 and the rotating ring plate 210, so that the rotation is more smooth.

[0035] As shown in Figure 2As shown in one of the embodiments, the sliding ring 230 is provided with a first sliding groove 2302 on the side away from the upper shell 110, and part of the ball 220 is embedded in the first sliding groove 2302. In this embodiment, the first sliding groove 2302 is used to accommodate part of the ball 220, so that the ball 220 can stably roll along the path of the first sliding groove 2302 during rotation. The ball 220 is adapted to the profile of the first sliding groove 2302, reducing the frictional resistance of the ball 220 during rolling, thereby improving the smoothness and accuracy of the rotation of the rotating ring plate 210.

[0036] As shown in one of the embodiments, the sliding ring 230 is provided with a first sliding groove 2302 on the side away from the upper shell 110, and part of the ball 220 is embedded in the first sliding groove 2302. In this embodiment, the first sliding groove 2302 is used to accommodate part of the ball 220, so that the ball 220 can stably roll along the path of the first sliding groove 2302 during rotation. The ball 220 is adapted to the profile of the first sliding groove 2302, reducing the frictional resistance of the ball 220 during rolling, thereby improving the smoothness and accuracy of the rotation of the rotating ring plate 210. Figure 2 As shown in one of the embodiments, the lower shell 120 is provided with a second sliding groove 1201, and part of the ball 220 is embedded in the second sliding groove 1201. The second sliding groove 1201 is aligned with the first sliding groove 2302 in the vertical direction. In this embodiment, the second sliding groove 1201 is aligned with the first sliding groove 2302 in the vertical direction, so that the two ends of the ball 220 are respectively embedded in the first sliding groove 2302 and the second sliding groove 1201. The ball 220 is simultaneously limited and guided by the first sliding groove 2302 and the second sliding groove 1201, reducing the deviation or bounce of the ball 220, thereby further improving the stability and reliability of the rotation of the rotating ring plate 210. In one of the embodiments, a plurality of balls 220 are arranged along the circumference of the sliding ring 230. In this embodiment, the plurality of balls 220 are arranged along the circumference of the sliding ring 230, so that the balls 220 can be uniformly distributed during rotation, thereby providing a stable support and rolling path. By arranging the balls 220 along the circumference, the contact force between the sliding ring 230 and the lower shell 120 is dispersed, improving the stability and load-bearing capacity of the rotating structure.

[0037] As shown in one of the embodiments, the sliding ring 230 is provided with a first sliding groove 2302 on the side away from the upper shell 110, and part of the ball 220 is embedded in the first sliding groove 2302. In this embodiment, the first sliding groove 2302 is used to accommodate part of the ball 220, so that the ball 220 can stably roll along the path of the first sliding groove 2302 during rotation. The ball 220 is adapted to the profile of the first sliding groove 2302, reducing the frictional resistance of the ball 220 during rolling, thereby improving the smoothness and accuracy of the rotation of the rotating ring plate 210. Figure 3 Figure 4 As shown in one of the embodiments, the horizontal rotating structure 10 further comprises a limit stop 500 connected to the upper shell 110 adjacent to the lower shell 120, and the rotating ring plate 210 is provided with a limit block 211 away from the lens seat assembly 400. In this embodiment, the limit stop 500 is fixed to the upper shell 110. When the limit block 211 of the rotating ring plate 210 contacts the limit stop 500, the limit stop 500 actively rotates the rotating ring plate 210, so that the rotating ring plate 210 can stop rotating when it reaches the preset position, preventing the rotating ring plate 210 from rotating excessively and causing damage to the lens seat assembly 400.

[0038] As shown in one of the embodiments, the sliding ring 230 is provided with a first sliding groove 2302 on the side away from the upper shell 110, and part of the ball 220 is embedded in the first sliding groove 2302. In this embodiment, the first sliding groove 2302 is used to accommodate part of the ball 220, so that the ball 220 can stably roll along the path of the first sliding groove 2302 during rotation. The ball 220 is adapted to the profile of the first sliding groove 2302, reducing the frictional resistance of the ball 220 during rolling, thereby improving the smoothness and accuracy of the rotation of the rotating ring plate 210. Figure 4 ​As shown in the drawings, in one of the embodiments, the upper shell 110 is further provided with a driving motor 111, the output end of the driving motor 111 is provided with a driving gear 112, the circumferential direction of the rotating ring plate 210 is provided with a rotating gear 212, and the driving gear 112 of the driving motor 111 is engaged with the outer edge of the rotating gear 212.

[0039] As shown in the drawings, Figure 5 As shown in the drawings, in one of the embodiments, the sliding ring 230 is provided with a mounting gap 2303, and the mounting gap 2303 is communicated with the circular groove 2301. In this embodiment, the mounting gap 2303 disperses and relieves the sliding ring 230, reduces the stress of the sliding ring 230 in the process of installing the ball 220, thereby facilitating the installation of the ball 220 in the circular groove 2301, and reducing the risk of damage to the sliding ring 230.

[0040] As shown in the drawings, Figure 3 As shown in the drawings, in one of the embodiments, the upper shell 110 is provided with an embedding groove 1101, and the lower shell 120 is provided with an embedding block 122 adjacent to one end of the upper shell 110, and the embedding block 122 is clamped in the embedding groove 1101.
