Technical Field

[0001] This utility model relates to the field of solar street light technology, specifically a foldable solar street light with a solar panel. Background Technology

[0002] Foldable solar streetlights utilize solar panels to convert light energy into electrical energy, which is then stored in batteries for nighttime illumination. The panels are foldable, unfolding to increase the light-receiving area and improve light absorption efficiency when in use; they can be folded away when not in use or during transportation and installation, reducing space occupation and enhancing convenience and safety. They are suitable for various applications including road lighting, public squares, temporary lighting, and lighting in remote areas.

[0003] Existing foldable solar streetlights typically use bolts or screws to connect the solar panels to the support frame. Due to repeated folding over long periods and exposure to outdoor environments, factors such as wind vibration, temperature changes, and rain corrosion can cause the bolts to loosen or corrode. This can lead to panel angle shifts, reduced light-receiving efficiency, and even structural instability or detachment. To ensure stability, regular inspection and tightening of the bolts are necessary, increasing maintenance frequency and labor costs, which is detrimental to long-term stable use and large-scale application.

[0004] To address this issue, this utility model provides a foldable solar street light with a solar panel to solve the problem of loose solar panel connecting bolts and frequent maintenance. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of the existing technology by providing a foldable solar street light with a battery panel, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a foldable solar street light, comprising a main body, a first solar panel being bolted to the top of the main body, first fixing blocks being fastened to both sides of the main body, a first rotating block being hinged to the side of the first fixing block, and a second solar panel and a third solar panel being welded and fixed to the ends of the first rotating blocks located on both sides of the main body away from the first fixing block, respectively, and the second solar panel and the third solar panel can be folded and folded up above the first solar panel;

[0007] The main body has several sets of protrusions integrally formed on its side. The contact surface of the first fixing block has grooves that match the protrusions. The protrusions and grooves are interlocked and connected to fix the first fixing block to the main body.

[0008] Preferably, the cross-sectional shape of the protrusion and the groove is rectangular.

[0009] Preferably, the cross-sectional shape of the protrusion and the groove is trapezoidal.

[0024] 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.

[0025] Example 1

[0026] Please see Figures 1-4 The illustration shows a foldable solar street light with a solar panel, comprising a main body 1. A first solar panel 101 is bolted to the top of the main body 1. First fixing blocks 201 are connected to both sides of the main body 1 by fasteners 203, preferably screws. A first rotating block 202 is hinged to the first fixing block 201. A second solar panel 102 and a third solar panel 103 are respectively welded and fixed to the ends of the first rotating blocks 202 located on both sides of the main body 1 away from the first fixing block 201. The second solar panel 102 and the third solar panel 103 can be folded and retracted above the first solar panel 101.

[0027] The structure of the second solar panel 102 and the third solar panel 103, which can be folded or unfolded relative to the first solar panel 101, allows the size of the solar panel to be adjusted as needed. During transportation, the second solar panel 102 and the third solar panel 103 can be folded above the first solar panel 101 to reduce the volume, save space, and facilitate transportation, handling, and storage. In use, the second solar panel 102 and the third solar panel 103 can be unfolded so that they are arranged parallel to the first solar panel 101, thereby increasing the light-receiving area and improving the light energy absorption efficiency.

[0028] The main body 1 has several sets of protrusions 205 integrally formed on its side. The contact surface of the first fixing block 201 has grooves 204 that mate with the protrusions 205. The protrusions 205 and grooves 204 are interlocked to fix the first fixing block 201 to the main body 1. The cross-sections of the protrusions 205 and grooves 204 are preferably rectangular. When installing the first fixing block 201, the grooves 204 on the first fixing block 201 are interlocked with the protrusions 205 on the side of the main body 1. Then, the first fixing block 201 is connected to the side of the main body 1 by screws. The protrusions 205 and grooves 204 form a stable interlocking structure, avoiding the problems of bolt loosening, displacement, or detachment caused by environmental factors during long-term outdoor use of traditional solar streetlights. This not only reduces maintenance frequency and labor costs but also improves the overall stability of the structure, thereby extending the service life of the solar streetlight.

[0029] The bottom of the main body 1 is provided with a combination structure 3 for connecting with the lamp post. The combination structure 3 includes a second fixing block 301 that is bolted to the bottom of the main body 1. A third fixing block 302 is welded to the bottom of the second fixing block 301. A fourth fixing block 303 is welded to the bottom of the third fixing block 302. A second rotating block 304 is rotatably mounted on the side of the fourth fixing block 303. A connecting cylinder 305 that connects to the lamp post is welded to the bottom of the second rotating block 304. A locking block 306 is welded to the side of the connecting cylinder 305. A locking groove 307 that matches the locking block 306 is opened at the bottom of the main body 1. The connecting cylinder 305 is locked in place by the locking block 306 and the locking groove 307.

[0030] A battery is slidably installed inside the main body 1. Limiting blocks 106 are welded and fixed on both sides of the battery. A limiting groove 105 adapted to the limiting blocks 106 is opened inside the main body 1. The limiting blocks 106 and the limiting groove 105 cooperate to fix the battery. A lamp 104 for lighting is installed at the bottom of the main body 1 by bolts.

[0031] Example 2

[0032] Figure 5 The structure of the second embodiment of this utility model is shown, and... Figure 1-4 Compared to the device shown, the difference is that the cross-sectional shape of the protrusion 205 and the groove 204 is trapezoidal. When installing the first fixing block 201, the first fixing block 201 is moved to slide and engage along the side wall of the main body 1. Installation and fixation are achieved by sliding in. The trapezoidal structure has a self-locking function when subjected to external force, which can further improve the stability of the connection between the first fixing block 201 and the main body 1 and reduce the frequency of maintenance.

[0033] Example 3

[0034] Figure 6The structure of the third embodiment of this utility model is shown. Compared with the first and second embodiments, the difference is that the cross-sectional shape of the protrusion 205 and the groove 204 is arc-shaped. Through the arc-shaped contact structure, the changes caused by external vibration and thermal expansion and contraction can be buffered, thereby improving the stability of the solar street light. When installing the first fixing block 201, the first fixing block 201 is moved to slide and engage along the side wall of the main body 1, and the installation and fixation are achieved by sliding in.

[0035] Working principle:

[0036] When transportation or storage is required, the second solar panel 102 and the third solar panel 103 can be rotated inward around the first rotating block 202. Through the hinge between the first fixed block 201 and the first rotating block 202, the second solar panel 102 and the third solar panel 103 can be stably folded and folded above the first solar panel 101, reducing the overall volume and facilitating transportation and storage. In use, the second solar panel 102 and the third solar panel 103 are unfolded outward, increasing the overall light-receiving area of ​​the solar panel and improving the light energy conversion efficiency.

[0037] When installing the first fixing block 201, the groove 204 on the first fixing block 201 engages with the protrusion 205 on the side of the main body 1. Then, the first fixing block 201 is connected to the side of the main body 1 by a screw. The protrusion 205 and the groove 204 form a stable engaging structure, avoiding the problems of bolt loosening, displacement, or detachment caused by environmental factors during long-term outdoor use of traditional solar streetlights. This not only reduces maintenance frequency and labor costs but also improves the overall stability of the structure, thereby extending the service life of the solar streetlight. Simultaneously, the screw further reinforces the connection between the first fixing block 201 and the main body 1, significantly reducing bolt loosening and maintenance frequency.

[0038] Furthermore, the battery can be installed inside the main body 1 through the sliding engagement of the limiting block 106 and the limiting groove 105, facilitating quick battery installation and replacement. The lamp 104 is bolted to the bottom of the main body 1 to provide nighttime illumination.
