[0004] In the process of realizing this application, the inventors discovered the following problems with the prior art: At present, most traditional solar lights are installed and used with a fixed structure. Because it is difficult to adjust the lighting angle of the lamp body according to different situations, the solar lights are inconvenient to use and the applicable range of solar lights is reduced. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a wind-following solar lamp that solves the problem that fixed-structure solar lamps have difficulty adjusting the lighting angle of the lamp body according to different situations.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a solar lamp with a tailwind function, comprising a lamp body shell and a main controller. An indicator light hole is provided at the midpoint of the lower end of the front face of the lamp body shell. A mounting rod is movably disposed at the midpoint of the lower end face of the lamp body shell. A mounting block is provided on the lower end face of the mounting rod. A damping shaft is provided at the connection between the mounting rod and the mounting block. A solar panel is provided on the rear face of the lamp body shell. A light-transmitting plate is provided on the front face of the lamp body shell. Locking blocks are provided at the upper and lower ends of both sides of the rear face of the lamp body shell. A driving mechanism is fixedly disposed on one side of the mounting block. The output end of the driving mechanism is fixedly connected to the damping shaft. The main controller is bidirectionally connected to an attitude control module, a power management module, and a light-controlled switch module.

[0007] Preferably, the drive mechanism includes a motor housing, inside which a stepper motor is fixedly installed, and at the output end of the stepper motor, an angle sensor is fixedly installed.

[0008] Preferably, the mounting block is rotatably disposed on the lower end face of the mounting rod, and the damping shaft is rotatably embedded at the rotatable connection between the mounting rod and the mounting block.

[0009] Preferably, the attitude control module includes an attitude control unit, which is connected to an angle adjustment module and a position memory module.

[0010] Preferably, the power management module includes a power management unit, which is connected to a charge / discharge management module and a display management module.

[0011] Preferably, the light-controlled switch module includes a light-controlled switch unit, which is connected to an ambient light acquisition module and a switch control module.

[0012] Preferably, the plurality of the locking blocks are snapped and fixedly disposed on the upper and lower ends of the rear end face of the lamp body housing, and one side of the plurality of the locking blocks is attached to both sides of the rear end face of the solar panel.

[0013] Preferably, the mounting rod is movably embedded at the midpoint of the lower end face of the lamp housing, and a mounting hole is provided at the midpoint of the lower end of the rear end face of the lamp housing.

[0014] Preferably, the size of the lamp housing can be selected according to different situations, and the solar panel is embedded at the midpoint of the rear end face of the lamp housing. The size of the solar panel can be changed according to the size of the lamp housing.

[0015] Preferably, the light-transmitting plate is embedded and fixedly disposed on the front end face of the lamp body housing, and the light-transmitting plate can be increased or decreased according to the size of the lamp body housing.

[0016] Working Principle: The lighting fixture uses a main controller as its core processing unit, coordinating the attitude control module, power management module, and light control switch module through a bidirectional communication bus. Regarding energy supply, the solar panel integrates a battery and inverter, converting and storing solar energy into electrical energy. The power management module's internal power management unit controls the charge / discharge management module to collect battery voltage and current signals in real time, using a coulomb integral algorithm to estimate the remaining capacity, thus achieving charge / discharge and overcharge / over-discharge protection. Simultaneously, the display management module drives power indicator lights embedded in the indicator light holes to visually display the charging progress and remaining power.

[0017] In terms of light sensing and switch control, the light control switch module receives the ambient light signal collected by the photosensitive sensor through the light control switch unit. After being digitized by the ADC, the switch control module executes a threshold comparison and delay confirmation algorithm with hysteresis loop. Based on the day and night changes, it automatically outputs the switch command to realize the automated light control management of the lamps.

[0018] Regarding attitude adjustment, when the illumination angle needs to be adjusted, the attitude control module, relying on the attitude control unit, controls the stepper motor in the drive mechanism to rotate the damping shaft through the angle adjustment module. This allows the mounting rod, which is embedded in the midpoint of the lower end face of the lamp housing, to adjust its angle relative to the mounting block within a certain range. Simultaneously, the angle sensor collects the rotation angle feedback signal in real time for position closed-loop calculation. Combined with the position memory module, this stores frequently used angle data, ensuring that the lamp can automatically adjust to the optimal attitude and self-lock position according to illumination requirements or user settings. Light passes through the light-transmitting plate embedded in the front face of the lamp housing to achieve directional illumination. The entire lamp uses clips to auxiliaryly fix the solar panel, and bolts in the mounting holes to fix the extension length of the mounting rod, ensuring structural stability.

[0019] This invention provides a wind-driven solar lamp. It has the following beneficial effects: This invention provides a solar lamp with a tailwind capability. Through the cooperation of a drive mechanism and a damping shaft, it achieves precise adjustment and self-locking of the lamp's illumination angle, significantly improving its flexibility and applicability. Simultaneously, it adopts a telescopic adjustment mounting rod and a modular design for the lamp body and accessories, allowing for specification adaptation and structural adjustment according to different usage scenarios and needs. Furthermore, it achieves automatic angle adjustment and position memory through a posture control module, combined with charge / discharge protection and visual display from a power management module, and automated light control management from a light control switch module, realizing intelligent, convenient, safe, and efficient use throughout the entire lifecycle of the solar lamp.

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figure 1-4As shown, this embodiment of the invention provides a wind-following solar lamp, including a lamp housing 1 and a main controller 12. An indicator light hole 5 is provided at the midpoint of the lower end of the front face of the lamp housing 1. An installation rod 2 is movably arranged at the midpoint of the lower end of the lamp housing 1. An installation block 3 is provided at the lower end of the installation rod 2. A damping shaft 6 is provided at the connection between the installation rod 2 and the installation block 3. A solar panel 7 is provided at the rear end of the lamp housing 1. A light-transmitting plate 4 is provided at the front end of the lamp housing 1. A locking block 8 is provided at the upper and lower ends of both sides of the rear end of the lamp housing 1. A drive mechanism 11 is fixedly arranged on one side of the installation block 3. The output end of the drive mechanism 11 is fixedly connected to the damping shaft 6.

[0024] Specifically, after opening an indicator light hole 5 at the lower midpoint of the front end face of the lamp housing 1, the power indicator light installed in the lamp housing can be embedded into the opened indicator light hole 5. The opened indicator light hole 5 can limit and assist the installation of the indicator light. After the mounting rod 2 is movably embedded at the midpoint of the lower end face of the lamp housing 1, the mounting rod 2 can be used to install and fix the lamp housing 1. At the same time, after the mounting block 3 is rotatably set on the lower end face of the mounting rod 2, the mounting rod 2 and the lamp housing 1 can be rotated 180 degrees around the mounting block 3 as the midpoint. After the damping shaft 6 is embedded in the rotating connection of the mounting block 3, the damping shaft 6 can be adjusted by the drive mechanism 11 to fix the angle of the mounting rod 2 and the lamp housing 1 after rotation. After the solar panel 7 is embedded in the rear end face of the lamp housing 1, the installed solar panel 7 can supply power to the lamp body. After the light-transmitting plate 4 is embedded in the front end face of the lamp housing 1, the light-transmitting plate 4 can protect the lamp panel in the lamp housing 1. The clips 8 installed on both sides of the rear end face of the lamp housing 1 can play an auxiliary role in fixing the embedded solar panel 7.

[0025] like Figure 5 As shown, the drive mechanism 11 includes a motor housing 1101, a stepper motor 1102 is fixedly installed inside the motor housing 1101, an angle sensor 1103 is fixedly installed at the output end of the stepper motor 1102, a mounting block 3 is rotatably installed on the lower end face of the mounting rod 2, and a damping shaft 6 is rotatably embedded at the rotatable connection between the mounting rod 2 and the mounting block 3.

[0026] Specifically, during use, the stepper motor 1102 is connected to one end of the damping shaft 6, and the damping shaft 6 is connected to the mounting rod 2. The rotation angle is detected by the angle sensor 1103, and the stepper motor 1102 drives the damping shaft 6 to rotate, thereby adjusting the illumination angle. The stepper motor 1102 has a self-locking function, and can be positioned for illumination after rotating to a suitable angle. The motor housing 1101 has heat dissipation holes on its surface to ensure heat dissipation of the internal structure.

[0027] The size of the lamp housing 1 can be selected according to different situations. The solar panel 7 is embedded at the midpoint of the rear end face of the lamp housing 1. The size of the solar panel 7 can be replaced according to the size of the lamp housing 1.

[0028] Specifically, the lamp housing 1 can be replaced with the traditional housing according to different usage scenarios and needs, thereby increasing the application range of the solar lamp. At the same time, the solar panel 7 embedded in the rear end of the lamp housing 1 can also be embedded in the lamp housing 1 according to the size of the lamp housing 1 to be used. The solar panel 7 integrates a battery and an inverter, which can realize the function of converting solar energy into electrical energy and storing it.

[0029] The mounting rod 2 is movably embedded at the midpoint of the lower end face of the lamp housing 1, and a mounting hole 9 is provided at the midpoint of the lower end of the rear end face of the lamp housing 1.

[0030] Specifically, after the mounting rod 2 is movably embedded into the midpoint of the lower end face of the lamp housing 1, the mounting rod 2 can be extended and adjusted inside the lower end of the lamp housing 1. After the mounting hole 9 is opened at the midpoint of the lower end of the rear end face of the lamp housing 1, the mounting bolt can be embedded in the mounting hole 9. After rotating the embedded bolt, one end of the bolt can be pressed against the outer surface of the mounting rod 2, thereby fixing the length of the mounting rod 2 after extension and retraction adjustment, which can better facilitate the use of the solar lamp.

[0031] Multiple clips 8 are fixedly installed on the upper and lower ends of the rear end face of the lamp body shell 1, and one side of the multiple clips 8 is attached to both sides of the rear end face of the solar panel 7.

[0032] Specifically, after the clip 8 is installed and fixed to the upper and lower ends of the rear end face of the lamp body shell 1 with fixing bolts, the installed clip 8 can better assist in fixing the solar lamp panel embedded in the rear end face of the lamp body shell 1, and prevent the solar panel 7 from accidentally falling off.

[0033] The light-transmitting plate 4 is embedded and fixedly installed on the front end face of the lamp body housing 1. The light-transmitting plate 4 can be added or removed according to the size of the lamp body housing 1.

[0034] Specifically, after the light-transmitting plate 4 is embedded and installed on the front end face of the lamp housing 1, the installed light-transmitting plate 4 can provide a certain protective effect on the lamp panel of the solar lamp. At the same time, the light-transmitting plate 4 installed on the front end face of the lamp housing 1 can also be selected and one or more light-transmitting rods can be embedded and installed on the front end face of the lamp housing 1 according to the size of the lamp housing 1.

[0035] like Figure 6-9As shown, the main controller 12 is bidirectionally connected to the attitude control module 13, the power management module 14, and the light control switch module 15. The attitude control module 13 includes an attitude control unit 1301, which is connected to an angle adjustment module 1302 and a position memory module 1303.

[0036] Specifically, the main controller 12, as the core processing unit for the entire lighting fixture, exchanges data and issues commands with the attitude control module 13, power management module 14, and light control switch module 15 through a bidirectional communication bus. It is responsible for coordinating the working sequence of each sub-light fixture, processing sensor feedback data, and executing control algorithms to achieve integrated intelligent control of lighting fixture attitude adjustment, power management, and automatic switching. The attitude control module 13, relying on the attitude control unit 1301, works with the stepper motor 1102 and the angle sensor 1103 to perform rotation within a 180-degree range through the angle adjustment module 1302. At the same time, it collects feedback signals from the angle sensor 1103 in real time to perform position closed-loop calculations. The position memory module 1303 records commonly used angle data through a memory to ensure that the lighting fixture can automatically adjust to the optimal attitude according to lighting requirements or user settings.

[0037] The power management module 14 includes a power management unit 1401, which is connected to a charge / discharge management module 1402 and a display management module 1403. The light control switch module 15 includes a light control switch unit 1501, which is connected to an ambient light acquisition module 1502 and a switch control module 1503.

[0038] Specifically, during use, the power management module 14 controls the charging and discharging management module 1402 to collect battery voltage and current signals in real time through the power management unit 1401. Combined with the coulomb integral algorithm, the remaining capacity is estimated, thereby realizing the functions of charging and discharging and overcharging and over-discharging protection for the solar panel 7 and its components. The display management module 1403 visually displays the charging progress and remaining power in the form of power indicator lights, realizing safe and efficient management of the battery throughout its entire life cycle.

[0039] The light control switch module 15, through the light control switch unit 1501 and in conjunction with the photosensitive sensor 10, converts the external light intensity into an electrical signal, which is then digitized by an ADC and transmitted to the switch control module 1503. The latter executes a threshold comparison and delay confirmation algorithm with hysteresis loop, and automatically outputs switch commands according to day and night changes, thereby realizing automated light control management of the lamps.
