Description

Technical Field

[0001] This utility model relates to the field of warning light technology, specifically a solar-powered warning light. Background Technology

[0002] Warning lights are devices that emit a specific light source to visually alert people in the surrounding area to relevant situations. They are widely used in scenarios such as road construction, engineering operations, and emergency rescue.

[0003] Currently, most warning lights on the market are powered by traditional batteries. Since batteries have limited power, they need to be replaced periodically, increasing operating costs and potentially causing the warning light to malfunction if the batteries are forgotten, thus affecting its effectiveness. Furthermore, existing warning lights often require bolts or other fasteners to be fixed in a specific location, making installation cumbersome. If the warning light needs to be moved to another location for operational purposes, the fasteners must be removed, resulting in inconvenient operation and poor flexibility. Utility Model Content

[0004] The purpose of this invention is to provide a solar-powered warning light to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A solar-powered warning light includes:

[0007] The solar cell is installed inside the housing and is attached to most of the lower surface of the light-transmitting glass sheet. A small area on the light-transmitting glass sheet is reserved where the solar cell is not attached. The area where the solar cell is not attached allows the light emitted by the LED to pass through the light-transmitting glass sheet, which serves as a warning and reminder.

[0008] The LED beads are fixedly soldered to the top surface of the circuit board, and multiple LED beads are arranged in a straight line along the length of the circuit board to form a row. Directly above the row of LED beads, the circuit board has through holes for mounting the circuit board. The circuit board is connected to the solar cells and the battery respectively through wires.

[0009] Preferably, the through hole is connected to the corresponding mounting post by a fixing screw. After the fixing screw passes through the through hole, it is tightened into the screw hole of the mounting post, pressing the circuit board tightly against the top surface of the mounting post. This keeps the circuit board parallel to the light-transmitting glass sheet on the device housing, ensuring that the light emitted by the lamp bead is directed toward the light-transmitting glass sheet at a vertical or near-vertical angle, facilitating the efficient transmission of light through the light-transmitting glass sheet and its outward dispersion.

[0010] Preferably, the mounting posts are fixedly connected to the mounting portions protruding on both sides of the receiving groove inside the housing. The number of mounting posts on each side is the same as the number of through holes on the circuit board, and the position of the mounting posts matches the position of the corresponding through holes on the circuit board.

[0011] Preferably, a storage battery is provided in the receiving slot. The storage battery is glued to the bottom of the receiving slot with adhesive. The storage battery is electrically connected to the circuit board through wires to provide the power required for the circuit board and LED beads to work.

[0012] Preferably, a switch is provided on the side of the housing. The switch is electrically connected to the circuit board via a wire. When the switch is operated, the lamp beads can be turned on and off by switching the circuit on and off.

[0013] Preferably, the upper end face of the outer shell is fixedly connected to an outwardly protruding outer edge, and a glass plate mounting groove is formed between the outer edge and the upper end face of the outer shell. The light-transmitting glass plate is interference-fitted with the glass plate mounting groove, and a disassembly groove is provided on both sides of the inner edge of the outer edge.

[0014] Preferably, a waterproof adhesive groove is fixedly connected to the upper end face of the glass plate mounting groove.

[0015] Preferably, the rear end of the housing is provided with a handle, the handle is connected to the rotating seat via a damping shaft, and the rotating seat is integrally formed and connected to the lower end face of the outer edge.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention, by setting solar cells attached to most of the lower surface of a light-transmitting glass sheet with a small reserved area, can not only fully absorb sunlight for photoelectric conversion, but also ensure that the light from the LED beads is not blocked, thus taking into account both energy storage and warning functions.

[0018] This invention, by setting a glass plate mounting groove, a waterproof adhesive groove, and a disassembly groove, ensures a stable interference fit between the transparent glass plate and the glass plate mounting groove, forms an effective waterproof barrier with the waterproof adhesive groove, and facilitates maintenance with the disassembly groove, thereby improving the equipment's sealing performance, durability, and maintainability.

[0019] This invention features a handle connected to the rotating base via a damping shaft. The damping force allows the handle to be fixed at any angle, and together with the outer shell, it can stably raise the warning light, ensuring a good warning angle in different scenarios and enhancing the reminder effect.

[0020] This utility model, by setting a handle with a through hole, can be fixed to a wall or bracket with bolts. Combined with a damping shaft, the outer shell can be rotated to adjust the angle, which increases the installation methods and improves the stability and flexibility of the equipment.

[0028] 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.

[0029] Example 1:

[0030] Please see Figures 1 to 5 This utility model provides a technical solution:

[0031] A solar-powered warning light includes a solar chip 6 and a handle 902. The solar chip 6 is attached to most of the lower surface of a light-transmitting glass sheet 5 and a small area is reserved for light from the LED beads 701 to pass through for warning purposes. Meanwhile, the handle 902 is rotatably connected to the outside of the housing 1 via a damping shaft 901, and the warning light can be raised by the tilt angle formed by the rotation in conjunction with the housing 1.

[0032] like Figure 1The outer casing 1 has an integrally formed outer edge 2 protruding outward on its upper surface. A glass plate mounting groove 4 is formed between the outer edge 2 and the upper surface of the outer casing 1. The light-transmitting glass plate 5 is tightly fitted into the mounting part 103 by interference fit to ensure a stable connection. The upper surface of the glass plate mounting groove 4 is also fixedly connected with a protruding waterproof adhesive groove 3 by waterproof adhesive. The waterproof adhesive groove 3 is preferably made of waterproof rubber material, which can effectively prevent rainwater from seeping into the internal components, enhance waterproofness, and improve the durability of the equipment in outdoor environments. Disassembly grooves 201 are provided on both sides of the inner edge of the outer edge 2 to facilitate the subsequent disassembly, maintenance, or replacement of the light-transmitting glass plate 5. The lower surface of the outer edge 2 has an integrally formed rotating seat 9, which provides a fulcrum for the installation of the handle 902.

[0033] like Figure 2 The solar cell 6 is firmly attached to the lower surface of the light-transmitting glass sheet 5 with adhesive, covering most of the area, so as to fully absorb sunlight for photoelectric conversion. At the same time, a small area is reserved on the light-transmitting glass sheet 5 where the solar cell 6 is not attached, so as to ensure that the warning light emitted by the lamp bead 701 can be emitted outward through the light-transmitting glass sheet 5 without obstruction, directly playing a reminder role, and avoiding the solar cell 6 from obstructing the warning light.

[0034] In this embodiment, the solar cell 6 and the light-transmitting glass sheet 5 are preferably connected with high-strength waterproof adhesive. The adhesive is evenly applied to the edge of the solar cell 6, so that the solar cell 6 is tightly bonded to the lower end face of the light-transmitting glass sheet 5, ensuring a tight fit between the two. The light-transmitting glass sheet 5 is tightly embedded in the glass sheet mounting groove 4 by interference fit. The upper end face of the glass sheet mounting groove 4 is fixed with waterproof adhesive to a raised waterproof groove 3. The upper end face of the waterproof groove 3 is attached to the lower end face of the light-transmitting glass sheet 5, forming a waterproof barrier to prevent rainwater or water vapor from seeping in from the gap between the light-transmitting glass sheet 5 and the mounting part 103, thus protecting the internal components such as the circuit board 7 and the LED beads 701.

[0035] When it is necessary to inspect or replace the internal components or the transparent glass plate 5, tools or fingernails can be used to insert into the disassembly slots 201 on both sides to simultaneously and easily lift the transparent glass plate 5 upwards and remove it from the glass plate mounting slot 4. Disassembly is simple and greatly reduces the difficulty and cost of maintenance.

[0036] like Figure 3The LED beads 701 are fixedly welded to the top surface of the circuit board 7. Multiple LED beads 701 are arranged in a straight line along the length of the circuit board 7 to form a continuous and uniform warning light band. Mounting posts 104 are fixedly connected to the protruding mounting portions 103 on both sides of the receiving groove 102 inside the housing 1. The number of mounting posts 104 on each side is the same as the number of through holes 903 on the circuit board 7, and their positions correspond one-to-one. The fixing screws 702 pass through the through holes 903 on the circuit board 7 and are tightened into the screw holes of the mounting posts 104, pressing the circuit board 7 tightly against the top surface of the mounting posts 104. This keeps the circuit board 7 parallel to the light-transmitting glass sheet 5 on the housing 1, so that the light emitted by the LED beads 701 can be directed towards the light-transmitting glass sheet 5 at a vertical or near-vertical angle, minimizing light refraction loss and improving light transmission efficiency.

[0037] When installing the circuit board 7, place the circuit board 7 with the soldered LED beads 701 on top of the mounting part 103 of the receiving groove 102 inside the housing 1, so that the two through holes 903 on the circuit board 7 are aligned with the two mounting posts 104 on the corresponding side of the mounting part 103. Then, pass the fixing screws 702 through the through holes 903 and tighten them into the screw holes of the mounting posts 104 until the circuit board 7 is tightly pressed against the top surface of the mounting posts 104, thus completing the installation. The structure is simple and can improve the installation efficiency.

[0038] It should be noted that there are two through holes 903 on the circuit board 7, and two mounting posts 104 are also provided on each side of the mounting portion 103 of the inner receiving groove 102 of the outer casing 1. Since there are mounting posts 104 on both sides, the circuit board 7 can be installed on the left mounting post 104 or the right mounting post 104 according to actual needs. For example, depending on the wiring situation, the length of the wires will be different. If the wire length is insufficient when installed on the left mounting post 104, it can be installed on the right mounting post 104, which enhances the flexibility and applicability of the device.

[0039] like Figure 4 A battery 8 is housed within a recess 102 inside the outer casing 1. The battery 8 is securely glued to the bottom of the recess 102, ensuring it will not loosen during movement or vibration. The battery 8 is electrically connected to the circuit board 7 via wires, continuously providing the circuit board 7 and the LED beads 701 with the necessary power. The electrical energy converted by the solar cells 6 can be stored in the battery 8, achieving energy reserve. A switch 101 is also provided on the side of the outer casing 1. The switch 101 is electrically connected to the circuit board 7 via wires, allowing operators to easily control the circuit's on / off state, thereby turning the LED beads 701 on and off.

[0040] When installing the battery 8, first apply an appropriate amount of glue evenly to the bottom of the receiving groove 102 inside the casing 1. Then place the battery 8 with the outer casing facing down at the bottom of the receiving groove 102, ensuring that the outer casing is in full contact with the glue. The adhesive will firmly bond the battery 8 to the bottom of the receiving groove 102. Connect the positive and negative terminals of the battery 8 to the corresponding terminals on the circuit board 7 via wires to complete the electrical connection between the battery 8 and the circuit board 7. Then connect the two terminals of the switch 101 to the corresponding control circuit terminals on the circuit board 7 with wires to ensure a secure connection.

[0041] After the solar cell 6 absorbs sunlight and converts it into electrical energy, it is transmitted to the battery 8 for storage via the charging circuit on the circuit board 7. When the warning light needs to be used, the switch 101 is closed, and the electrical energy stored in the battery 8 is transmitted to the lamp bead 701 via the circuit board 7 to power the lamp bead 701 and make it light up. When the switch 101 is opened, the circuit is interrupted, and the lamp bead 701 stops working. The switch 101 controls the opening and closing of the control circuit to achieve convenient control of the lamp bead 701, improving the flexibility and convenience of use.

[0042] Furthermore, this warning light integrates an algorithm-controlled intelligent operating mode. The clock module on the integrated circuit board 7 can acquire real-time time information. When it detects that evening (e.g., 18:00), the algorithm automatically triggers the control logic. Without manual operation of switch 101, the electrical energy stored in battery 8 is automatically transferred to LED bead 701 via circuit board 7 to illuminate it. At dawn (e.g., 7:00), the algorithm automatically cuts off the power supply, and LED bead 701 stops working. This is suitable for unattended scenarios, ensuring timely nighttime warnings while avoiding unnecessary power consumption during the day, thus improving the intelligence level and energy efficiency of the equipment.

[0043] Specifically, the clock module is preferably DS1302, and the circuit board is equipped with a microcontroller, preferably STC89C52.

[0044] Specifically, the outer casing of battery 8 is preferably made of PVC material that is wear-resistant, corrosion-resistant, and has a certain degree of insulation, which wraps around the battery to protect the battery body.

[0045] like Figure 5 The handle 902 is rotatably connected to the rotating seat 9 via the damping shaft 901. When the handle 902 is rotated, the damping force of the damping shaft 901 can make the handle 902 stop stably at any angle. With the help of the arc-shaped tilt angle formed after the handle 902 is rotated, it cooperates with the outer edge 2 of the outer shell 1 to make the warning light stand up stably, ensuring that a good warning angle can be maintained in different scenarios and enhancing the reminder effect.

[0046] Specifically, the outer shell 1 and handle 902 are preferably made of ABS plastic. This material is lightweight, which significantly reduces the overall weight of the warning light, making it easy to carry and move. It also has good impact resistance and weather resistance, allowing it to withstand certain collisions and exposure to wind and sun in complex outdoor environments without easily being damaged, effectively extending the service life of the equipment. The waterproof groove 3 is preferably made of EPDM rubber, which has superior aging resistance and waterproof performance, maintaining good elasticity and sealing for a long time, ensuring the effectiveness of the waterproof barrier. The core component of the damping shaft 901 is preferably made of wear-resistant alloy material to ensure that it is not easily worn during long-term rotational use, maintaining a stable damping effect, and allowing the handle 902 to be reliably fixed at any angle.

[0047] When the warning light is in use, the solar panel 6 absorbs sunlight, converts it into electrical energy, and stores it in the battery 8. To activate the warning light, close the side switch 101 on the outer casing 1. Power from the battery 8 is then transmitted to the LED 701 via the circuit board 7. The light from the LED 701 passes through the pre-reserved area of ​​the translucent glass 5. To adjust the warning angle, rotate the handle 902 and secure it using the damping shaft 901. Disconnect the switch 101 after use. For maintenance, insert a tool or fingernail into the disassembly slots 201 on both sides of the outer edge 2, and lift the translucent glass 5 upwards to inspect internal components or replace the glass.

[0048] Example 2:

[0049] Please see Figure 6 This utility model provides a technical solution that is basically the same as that in Embodiment 1, with slight differences:

[0050] like Figure 6 The handle 902 and the rotating base 9 are rotatably connected via a damping shaft 901, allowing for highly flexible rotation of the handle 902, whether it's a small-angle fine-tuning or a large-angle flip. By applying external force to the handle 902 and pushing or pulling it in the desired direction, the damping force inside the damping shaft 901 is overcome, causing the damping shaft 901 to rotate. This, in turn, drives the handle 902 to rotate flexibly around the rotating base 9. Once the handle 902 has rotated to the appropriate angle, releasing the external force immediately stops the shaft from rotating further, stabilizing the handle 902 at the current angle. This forms a stable support structure with the outer casing 1, allowing the warning light to stand stably without additional fixing devices. It can also be easily lifted from its current surface without cumbersome disassembly steps, making it convenient to move the warning light to other locations for use.

[0051] By engaging the handle 902 with the outer edge 2 of the housing 1, the warning light can be stably mounted on any flat surface such as the ground, tabletop, or steps, without the need for additional fixing devices, greatly enhancing its adaptability to various usage scenarios. Regardless of the environment, the angle can be adjusted to ensure that the light from the warning light is presented at the optimal viewing angle, allowing others to clearly observe the warning signal and further enhancing the warning effect.

[0052] Example 3:

[0053] This utility model provides a technical solution that is basically the same as that in Embodiment 2, with the following slight differences:

[0054] The handle 902 has a through hole 903, which corresponds to a bolt hole on a wall, bracket, or other object. A bolt is passed through the through hole 903 and tightened into the bolt hole, allowing the handle 902 to be fixed to the wall or bracket. Once the handle 902 is fixed, it is connected to the outer casing 1 via a damping shaft 901. The outer casing 1 can then be rotated, and the damping force of the shaft 901 allows it to remain stable at the desired angle during rotation. This changes the orientation of the warning light, making the warning light more easily visible and improving its practicality and flexibility in different installation scenarios.

[0055] After fixing the handle 902 to the wall or bracket with bolts, the tight fit between the bolts, through holes 903, and bolt holes forms a strong connection, making the warning light installation more secure. Even under the influence of external factors such as wind and vibration, it is not easy to loosen or shift, ensuring the stability of the equipment during long-term use. This fixing method complements the method of supporting the handle 902 vertically, allowing users to freely choose the installation method according to the actual scenario and usage needs. When it is necessary to use it in one scene for a long time, it can be installed with bolts; if the warning light needs to be moved to another place after a short period of use, it can be directly placed on a flat surface using the handle 902.

[0056] All other parts of this utility model not described herein are the same as existing technologies, or are known technologies, or can be implemented using existing technologies, and will not be described in detail here.

[0057] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
