[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0028] Example 1

[0029] The present invention provides an energy-saving and high-efficiency solar street lamp for outdoor lighting, such as Figures 1 to 7 As shown, it includes a lamp pole 1, a lamp body 2 is fixedly installed on the top of the lamp pole 1, a connecting tube 5 is fixedly installed on the center of the top of the lamp body 2, a lamp cap 4 is fixedly connected to the top of the connecting tube 5, hinges 9 are symmetrically installed on four sides of the bottom end of the lamp cap 4, a photovoltaic panel 3 is fixedly connected to one end of the hinge 9, a No. 1 rotating seat 7 is fixedly installed in the middle of the back of four photovoltaic panels 3, four No. 1 rotating seats 7 are rotatably connected inside the four No. 1 rotating seats 7, a No. 2 rotating seat 14 is sleeved on the outer surface of one end of the four support rods 12, a No. 3 fixing ring 15 is fixedly installed between the bottom ends of the four No. 2 rotating seats 14, and an electric telescopic rod 11 is fixedly installed inside the connecting tube 5 in the middle of the top of the No. 3 fixing ring 15.

[0030] like Figure 3 and 5 As shown, two slides 16 are symmetrically installed at the bottom edge of the back of the four photovoltaic panels 3, and the same outer frame 17 is slidably installed between the two slides 16. The four outer frames 17 are fixedly installed with rotating shafts 22. The outer surfaces of the four rotating shafts 22 are rotatably connected with light boards 18. Two No. 1 connecting ropes 8 are fixedly installed at the top of the four outer frames 17. The other ends of several No. 1 connecting ropes 8 are fixedly installed at the top of the No. 3 fixing ring 15. The movable end of the electric telescopic rod 11 drives the No. 3 fixing seat to slide toward the top of the connecting pipe 5, so that the No. 3 fixing ring 15 and the No. 1 fixing The distance between the rings 6 becomes shorter, thereby shortening the length of the No. 1 connecting rope 8 between the No. 3 fixing ring 15 and the No. 1 fixing ring 6, so that the range of motion of the other end of the connecting rope is expanded. According to the principle of gravity, the other end of the No. 1 connecting rope 8 is affected by the weight of the outer frame 17, and the outer frame 17 drives the connecting rope to slide along the slide seat 16 toward the bottom end of the photovoltaic panel 3. At the same time, the slide seat 16 drives the lamp board 18 to slide toward the bottom end of the photovoltaic panel 3. The dynamic adjustment of the position of the lamp board 18 can cooperate with the lamp body 2 of the street lamp. The lamp board 18 slides downward close to the ground, which can increase the light intensity in the area and improve the lighting effect.

[0031] like Figure 3 and 5As shown, the bottom ends of both sides of the four lamp panels 18 are fixedly installed with a No. 3 rotating seat 19, and a No. 2 connecting rope 20 is rotatably installed inside the No. 3 rotating seat 19. One end of several No. 2 connecting ropes 20 are fixedly installed with rope buckles 23. Two relatively fastening ropes 23 are fixedly installed on the back of the same photovoltaic panel 3. As the lamp panel 18 slides toward the bottom end of the photovoltaic panel 3, one end of the No. 2 connecting rope 20 is driven to slide toward the bottom end of the photovoltaic panel 3. With the lamp panel 18 as a reference, the photovoltaic panel 3 moves toward the direction of the lamp cap 4 at this time. The movement of the photovoltaic panel 3 drives the rope buckle 23 to move, and the rope buckle 2 The No. 2 connecting rope 20 on 3 pulls the No. 3 rotating seat 19 connected to the other end. At this time, the No. 2 connecting rope 20 rotates in the No. 3 rotating seat 19, and the lamp board 18 rotates around the rotating shaft 22, so that the angle between the No. 2 connecting rope 20 and the photovoltaic panel 3 gradually becomes smaller, and the angle between the lamp board 18 and the outer frame 17 gradually becomes smaller, and finally the angle between the lamp board 18 and the photovoltaic panel 3 becomes smaller. As the photovoltaic panel 3 gradually opens, the opening angle of the lamp board 18 is expanded, which can effectively cover a wider shadow area and expand the illumination range.

[0032] like Figure 3 and 4 As shown, a slide hole is opened on the outer surface of the connecting tube 5, and the No. 3 fixing ring 15 passes through the slide hole and is connected to the movable end of the electric telescopic rod 11, providing a connection space for the No. 3 fixing ring 15 and the electric telescopic rod 11, facilitating the connection between the No. 3 fixing ring 15 and the electric telescopic rod 11, so that the electric telescopic rod 11 can drive the No. 3 fixing ring 15 to move longitudinally.

[0033] like Figure 3 and 5 As shown, a No. 1 fixing ring 6 is fixedly installed on the outer surface of the connecting tube 5, and holes are set on the surface of the No. 1 fixing ring 6. A fixing buckle 21 is fixedly installed on the back side of the photovoltaic panel 3 at both sides of the No. 1 rotating seat 7. The No. 1 connecting rope 8 passes through the fixing buckle 21 and the hole. The fixing ring and the fixing buckle 21 guide the No. 1 connecting rope 8, which can ensure that the No. 1 connecting rope 8 slides in the correct direction and prevent the No. 1 connecting rope 8 from being entangled on other parts.

[0034] like Figure 3 and 4 As shown, a plurality of dust-proof strips 13 are arranged on the inner wall of the connecting tube 5, and the dust-proof strips 13 block the slide hole, and the dust-proof strips 13 are fixedly installed at the top and bottom ends of the No. 3 fixing ring 15, so that when the No. 3 fixing ring 15 moves longitudinally, the dust-proof strips 13 move longitudinally together, and during the longitudinal movement of the dust-proof strips 13, the dust-proof strips 13 always block the slide hole, so as to prevent dust and insects from entering into the interior of the connecting tube 5, and prevent the interior of the connecting tube 5 from being damaged.

[0035] like Figure 3 and 4As shown, a No. 2 fixing ring 10 is fixedly installed at one end of the electric telescopic rod 11, and the No. 2 fixing ring 10 is fixedly installed inside the connecting tube 5. The No. 2 fixing ring 10 fixes the electric telescopic rod 11 to prevent the electric telescopic rod 11 from shaking while extending and retracting, thereby affecting the sliding of the No. 3 fixing ring 15.

[0036] like Figure 2 and 5 As shown, fixing grooves are opened on both sides of the front side of the lamp board 18, and the No. 3 rotating seat 19 is fixedly installed at the bottom end of the fixing groove in the lamp board 18 to provide space for the No. 2 connecting rope 20 and the rope buckle 23. When the angle between the lamp board 18 and the photovoltaic panel 3 becomes smaller, the rope buckle 23 and the No. 2 connecting rope 20 gradually approach the lamp board 18. At this time, the rope buckle 23 gradually approaches the top of the fixing groove to prevent the protruding rope buckle 23 from bumping against the surface of the lamp board 18 when the lamp board 18 approaches the photovoltaic panel 3, causing damage to the light board 18.

[0037] like Figure 6 and 7 As shown, a gutter 24 is fixedly installed at one end of the back side of the photovoltaic panel 3. The gutter 24 is located between the gaps of the two photovoltaic panels 3. The rainwater flowing in from the gaps between the two photovoltaic panels 3 is guided by the gutter 24 so that the rainwater flows along the gutter 24 to the bottom end of the photovoltaic panel 3, thereby preventing the rainwater from entering the interior of the photovoltaic panel 3 along the gaps and causing problems such as short circuit in the lifting structure.

[0038] Working principle: On a clear day, the electric telescopic rod 11 is started, and the movable end of the electric telescopic rod 11 drives the No. 3 fixing seat to slide toward the top of the connecting tube 5, and the No. 3 fixing seat pushes the support rod 12 to move upward, and the support rod 12 rotates in the No. 2 rotating seat 14 and the support rod 12 pushes the No. 1 rotating seat 7, so that the support rod 12 rotates along the No. 1 rotating seat 7, so that the angle between the support rod 12 and the photovoltaic panel 3 changes, and the photovoltaic panel 3 is unfolded outward from the folded state, and at the same time, the distance between the No. 3 fixing ring 15 and the No. 1 fixing ring 6 changes. The outer frame 17 is used to move the No. 1 connecting rope 8 to the bottom of the photovoltaic panel 3. The outer frame 17 drives the connecting rope to slide along the slide 16 toward the bottom of the photovoltaic panel 3. The slide 16 drives the light board 18 to slide toward the bottom of the photovoltaic panel 3. The dynamic adjustment of the position of the light board 18 can cooperate with the light body 2 of the street lamp. The light board 18 slides down close to the ground, which can increase the light intensity in the area and improve the lighting effect.

[0039] As the lamp panel 18 slides toward the bottom of the photovoltaic panel 3, one end of the second connecting rope 20 is driven to slide toward the bottom of the photovoltaic panel 3. With the lamp panel 18 as a reference, the photovoltaic panel 3 moves toward the lamp cap 4 at this time. The movement of the photovoltaic panel 3 drives the rope buckle 23 to move. The second connecting rope 20 on the rope buckle 23 pulls the third rotating seat 19 connected to the other end. At this time, the second connecting rope 20 rotates in the third rotating seat 19, and the lamp panel 18 rotates with the rotating shaft 22 as the axis, so that the angle between the second connecting rope 20 and the photovoltaic panel 3 gradually becomes smaller. The angle between the lamp board 18 and the outer frame 17 gradually becomes smaller, and finally the angle between the lamp board 18 and the photovoltaic panel 3 becomes smaller. As the photovoltaic panel 3 gradually opens, the opening angle of the lamp board 18 expands, which can effectively cover a wider shadow area and expand the irradiation range. Through the opening of the photovoltaic panel 3 and the change of the angle and irradiation range of the lamp board 18, a brighter and longer-lasting lighting effect is achieved in cooperation with the street lamp body 2, making the entire area look neater and more orderly, greatly improving the overall aesthetics.

[0040] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
