Detailed Implementation

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0021] Example 1, referring to Figures 1 to 3 This is the first embodiment of the present invention. This embodiment provides a solar lamp that can adjust the tilt angle of the solar panel to improve the light energy utilization efficiency. It includes: a cylindrical transparent shell 1, a pair of end caps 2, a V-shaped strip bracket 3, a solar panel 5, a battery assembly 6, an LED light sheet 4, and a control circuit.

[0022] The cylindrical transparent outer shell 1 is made of a high-transmittance, UV-resistant material, and its two ends are sealed by end caps 2. A first friction positioning structure is provided between the contact surfaces of the end caps 2 and the outer shell to lock the position after the end caps 2 are rotated relative to each other. The outer side of the end caps 2 is rotatably mounted on an external bracket, which is fixed to the wall by expansion screws, so that the entire lamp can be adjusted relative to the outer shell by the wall support.

[0023] The V-shaped strip support 3 is coaxially disposed inside the outer casing, and its two ends are circumferentially fixedly connected to the end cover 2, so that the V-shaped strip support 3 can rotate relative to the outer casing around the axis with the end cover 2. The inner sidewall of the V-shaped opening of the V-shaped strip support 3 is provided with a sliding groove 8 along the axial direction. The edge of the solar panel 5 slides in the sliding groove 8, and a second friction positioning structure is provided between the contact surfaces, so as to keep the position of the solar panel 5 stable after sliding adjustment.

[0024] The battery assembly 6 is fixed inside the V-shaped opening of the V-shaped strip bracket 3 to store the electrical energy output by the solar panel 5. The outer walls on both sides of the V-shaped strip bracket 3 have axially arranged lamp holder slots 9, with at least two LED lamp pieces 4 fixedly embedded in their respective slots. A control circuit is installed inside one of the end caps 2 and is electrically connected to the LED lamp pieces 4, the solar panel 5, and the battery assembly 6 to achieve energy management and lighting control.

[0025] Working principle of Example 1: In use, the solar panel 5 converts light energy into electrical energy and stores it in the battery assembly 6. The control circuit drives the LED light sheet 4 to work according to lighting needs. When it is necessary to adjust the light-receiving angle of the solar panel 5, the user can manually rotate either end cover 2, causing the V-shaped strip bracket 3 fixedly connected to it to rotate relative to the outer casing, thereby causing the solar panel 5 to rotate synchronously, achieving optimized matching of the light direction. In addition, the user can also move the solar panel 5 along the front sliding groove 8 of the cylindrical transparent outer casing 1 to further fine-tune its position, ensuring optimal light exposure in different seasons and time periods.

[0026] Technical effects of Example 1: 1. Flexible angle adjustment: By setting detachable end caps 2 at both ends of the cylindrical transparent shell 1, and adopting a first friction positioning structure between the contact surface of the end caps 2 and the shell, the V-shaped strip support 3 can rotate around the axis of the shell with the end caps 2, thereby realizing the tilt angle adjustment of the solar panel 5 to adapt to different light directions and improve photovoltaic conversion efficiency.

[0027] 2. Stable Position Locking: The inner wall of the V-shaped opening of the V-shaped strip bracket 3 is provided with a sliding groove 8, which slides and engages with the edge of the solar panel 5. In conjunction with the second friction positioning structure, the solar panel 5 can maintain a stable position after sliding adjustment, avoiding position displacement due to vibration or external force.

[0028] 3. Compact structure and high integration: The battery assembly 6 is fixed inside the V-shaped strip bracket 3, the LED light sheet 4 is embedded in the light sheet placement slots 9 on both sides of the bracket, and the control circuit is integrated into the end cover 2, forming a lighting design with a compact overall structure and high internal space utilization.

[0029] 4. Easy maintenance and assembly: The detachable design of the end cap 2 makes it easy for users to maintain, replace or upgrade internal components without affecting the overall structure.

[0030] 5. Balancing appearance and protection: The cylindrical transparent housing 1 not only provides a consistent overall appearance for the lamp, but also provides good protection for the internal components, adapting to the needs of complex outdoor environments.

[0031] Example 2, refer to Figure 1 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment further optimizes the structural design of the end cap 2 based on embodiment 1, so as to improve the control convenience and charging convenience of the solar lamp.

[0032] The outer surface of the end cap 2, which contains the embedded control circuit, is provided with a button assembly 10 and a charging port. The button assembly 10 includes at least one silicone button, which is electrically connected to the control circuit and is used to realize functions such as switching lighting modes, adjusting brightness, or power on / off. The charging port is also electrically connected to the control circuit and is used to wire charge the battery assembly 6 through an external power supply device in cases of insufficient light or prolonged rainy weather.

[0033] To enhance the protection of the charging port, the end cover 2 has a connection opening, and the charging port is located inside the connection opening. The connection opening is detachably covered by a sealing cover 11, and the outer edge of the sealing cover 11 has radially outwardly extending opening protrusions 12, so that the user can grasp and open it when charging is needed. At the same time, the sealing cover 11 provides waterproof and dustproof protection when not charging.

[0034] Working principle of Example 2: When users need to adjust the lighting mode or switch the lights on and off, they can operate directly via the silicone button. The button signal is processed by the control circuit and drives the LED light panel 4 to work. When the solar panel 5 cannot provide sufficient power due to weather or installation location, the battery assembly 6 can be charged via an external power source through the charging port. The charging port is protected by a sealing cover 11 when not in use, effectively preventing rainwater and dust from entering the end cover 2 and ensuring the long-term stable operation of the control circuit and electrical connections.

[0035] Technical effects of Example 2: 1. The button assembly 10 has a simple structure and intuitive operation, and can realize a variety of lighting control functions, improving the ease of use of the lamps.

[0036] 2. The charging port provides backup power for the lights in severe weather or special environments, improving their battery life.

[0037] 3. The design of the sealing cover 11 and the opening protrusion 12 not only improves the protection level of the charging port, but also takes into account the ease of operation for users, making it suitable for long-term outdoor use.

[0038] 4. When used in conjunction with Example 1, it can provide reliable manual control and emergency charging functions while maintaining efficient use of solar energy, enabling the lamp to work stably in various application scenarios.

[0039] Example 3, referring to Figure 1 and Figure 3 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment further optimizes the structural design of the V-shaped strip bracket 3 to improve its overall rigidity and installation stability.

[0040] At least one set of positioning reinforcing ribs 13 are provided on the outer surfaces of the two side walls of the V-shaped strip bracket 3 and on the outer surface of the back opening of the bottom wall of the V-shaped structure. The positioning reinforcing ribs 13 extend along the axial direction of the V-shaped strip bracket 3, and their two ends are fixedly connected to the inner side walls of a pair of end caps 2, thereby forming a stable connection path between the end caps 2 and the V-shaped strip bracket 3, reducing the possibility of bracket deformation or end cap 2 loosening during long-term use.

[0041] The positioning reinforcing rib 13 has a circular cross-section and protrudes axially from the outer surface of the side wall and bottom wall of the V-shaped strip bracket 3. The maximum protrusion height of the positioning reinforcing rib 13 is 0.5-0.8 times its cross-sectional diameter, ensuring sufficient strength while avoiding excessive internal space occupation. To reduce overall weight and improve processing efficiency, the positioning reinforcing rib 13 has a cylindrical weight-reducing cavity running axially through it. This weight-reducing cavity can reduce material usage without significantly affecting structural rigidity and facilitates mold forming and demolding.

[0042] Working principle of Example 3: During operation, the V-shaped strip bracket 3 achieves overall rotational adjustment through its fixed connection to the end cap 2 at both ends. The positioning reinforcing rib 13, acting as a strengthening component of the bracket, not only shares the load from the solar panel 5, LED light sheet 4, and battery assembly 6 during rotation, but also provides stable support when the end cap 2 is rotated and locked, preventing the bracket from twisting or deforming. Simultaneously, the weight-reducing cavity reduces the bracket's weight while maintaining strength, thereby lowering the torque requirement for rotating the end cap 2.

[0043] Technical effects of Example 3: 1. The setting of the positioning reinforcing rib 13 effectively improves the structural strength and deformation resistance of the V-shaped strip bracket 3, and extends the life of the lamp for long-term outdoor use.

[0044] 2. The design of a circular cross-section and a specific protrusion height improves support stability while also taking into account space utilization and aesthetic harmony.

[0045] 3. The application of cylindrical weight-reducing cavity enables the support to significantly reduce weight while maintaining high strength, thereby reducing the resistance and energy consumption of rotation adjustment.

[0046] 4. The positioning reinforcing rib 13 is directly fixed to the inner wall of the end cap 2, forming a multi-point force path, which further improves the connection between the end cap 2 and the bracket.

[0047] Example 4 is the fourth embodiment of this utility model. Unlike the previous embodiment, this embodiment further optimizes the adjustment and positioning structure of the solar panel 5, the heat dissipation structure of the battery component 6, and the sealing structure between the end cover 2 and the outer shell, so as to improve the stability of the lamp, heat dissipation performance and protection capability.

[0048] The inner wall of the slide groove 8 on the inner side wall of the V-shaped opening of the V-shaped strip bracket 3 is provided with multiple limiting grooves (not shown) at intervals along its length. The solar panel 5 has elastic clips (not shown) on its own edge. When the solar panel 5 slides along the slide groove 8 to the target position, the elastic clips can be inserted into the corresponding limiting grooves, thereby achieving quick positioning and stable fixation without additional tools.

[0049] Reference Figure 3 A metal mounting plate 14 is fixedly installed on the inner side of the V-shaped bottom wall of the V-shaped strip bracket 3, and the battery assembly 6 is attached to the surface of the metal mounting plate 14. Heat dissipation fins 15 extend from the side of the metal mounting plate 14 away from the battery. The heat dissipation fins 15 extend through the V-shaped bottom wall to the outside, so that the heat generated by the battery during operation can be efficiently conducted to the outside air, avoiding high temperature from affecting battery performance and life.

[0050] An annular sealing groove (not shown) is provided at the connection between the end cap 2 and the cylindrical transparent outer shell 1. A double-lip sealing ring (not shown) is nested in the sealing groove. The inner lip of the double-lip sealing ring is in close contact with the side wall of the end cap 2, and the outer lip is in close contact with the inner wall of the outer shell, forming a double sealing structure to effectively prevent moisture and dust from entering the lamp.

[0051] Working principle of Example 4: In use, the user can push the solar panel 5 along the slide 8 until the elastic clip engages with the target limiting groove, achieving precise positioning; this structure can maintain the stability of the solar panel 5 even under vibration or wind. The heat generated by the battery assembly 6 during charging and discharging is quickly conducted to the heat dissipation fins 15 through the metal mounting plate 14 and further released into the outside air, ensuring the battery operates within a safe temperature range. The double-lip sealing ring forms an effective sealing barrier at the mating point between the end cap 2 and the outer casing, blocking external rainwater and dust, ensuring the reliable operation of the internal electrical components.

[0052] Technical effects of Example 4: 1. Multiple limiting slots and elastic clips work together to achieve fast, accurate and stable adjustment of the solar panel position, improving the efficiency of light energy utilization.

[0053] 2. The combination of the metal mounting plate 14 and the exposed heat dissipation fins 15 significantly improves the heat dissipation efficiency of the battery and extends its service life.

[0054] 3. The double-lip sealing ring enhances the protection level of the lamp, making it suitable for various harsh outdoor environments.

[0055] 4. The three optimization measures work together to give the lighting fixtures higher stability, durability and energy efficiency during long-term outdoor use.
