Technical Field

[0001] This utility model relates to the field of solar street light technology, and in particular to a solar street light head structure with an integrated lithium battery pull-out maintenance compartment, which is suitable for integrated street light design that facilitates convenient maintenance and battery replacement in outdoor road lighting systems. Background Technology

[0002] At present, solar street lights are widely used in urban roads, rural roads, parks and scenic spots for lighting, and are valued for their energy saving, environmental protection and convenient installation. In traditional solar street lights, lithium batteries are mostly installed by external mounting or underground burial, which has the following defects: (1) Inconvenient maintenance: Replacing batteries requires disassembling the light pole or opening the underground box, which is time-consuming and laborious; (2) Safety hazards: External mounting structure batteries are easily affected by external impact, sun exposure or rain, which poses a risk of short circuit or damage; (3) Dispersed structure: Lithium batteries, lighting heads and controllers are often installed independently, resulting in complicated wiring, increased costs and low integration.

[0003] To address the aforementioned issues, some streetlights have begun to integrate batteries into the lamp head. However, these are mostly fixed installations, making replacement difficult later on. Furthermore, inadequate heat dissipation and sealing designs further limit their widespread adoption in large-scale applications. Therefore, developing a structurally sound integrated lithium-ion battery solar streetlight lamp head with a pull-out replacement function and good protective performance has become a key technological requirement for improving product maintenance efficiency and application stability.

[0018] Example 1: As Figure 1As shown, a solar street light head structure with an integrated lithium battery pull-out maintenance compartment includes a head housing (1), a lighting module (2), a control module (3), and a lithium battery compartment (4). The head housing (1) is a hollow structure with the lighting module (2) installed at the front end. The control module (3) is located on top of the housing. The lithium battery compartment (4) is installed inside the rear section of the head housing (1) via a slide rail assembly (5). It adopts a drawer-type structure and can be pulled out along the guide rail for easy replacement later. To prevent the battery compartment from completely detaching from the housing, a limiting block is provided at the end of the slide rail assembly. This block, together with the limiting groove structure on the slider, forms the limit position for pulling out, preventing excessive pulling and detachment. The slider adopts a slot-type sliding fit, which has a certain friction and anti-slip design, improving structural stability. To accommodate lithium batteries of different capacities or sizes, the lithium battery compartment (4) can be modularly designed according to the number and volume of the battery cells. Multiple guide rail mounting positions and limit slots are reserved inside the housing, allowing for the replacement or sliding installation of battery compartment structures of different lengths. The positions of the slide rail assembly and locking mechanism are adjustable to ensure compatibility with battery modules of various specifications without replacing the entire lamp head housing.

[0019] Example 2: Figure 2 and Figure 3 As shown, the slide rail assembly (5) includes two guide rails on the left and right sides and a slider that slides with them. The guide rails are fixed to both sides of the inner wall of the lamp head housing (1), and the slider is installed at the bottom of the lithium battery compartment (4). The sliding fit ensures a smooth and stable pull-out process. The guide rails are made of stainless steel, which has good corrosion resistance and mechanical strength. To prevent the battery compartment from accidentally falling off during the pull-out process, the end of the guide rail is provided with a limiting boss structure, and the tail of the slider is provided with a stop groove that matches it, forming a mechanical limiting fit; at the same time, an elastic buffer pad is provided between the slider and the guide rail to improve the shock resistance and prevent the slide rail from falling off due to loosening. The structure has reserved installation holes, which facilitates the subsequent addition of safety lock pins or auxiliary buckles according to different application scenarios, thereby improving the overall operation stability and maintenance safety.

[0020] Example 3: Figure 4As shown, the front end of the lithium battery compartment (4) is provided with a locking mechanism (6), which is a spring-return type buckle structure. The buckle head is fastened to the slot inside the housing by means of the buckle head. The buckle head is set on the lower side of the front end of the battery compartment and fixed to the buckle seat by screws. The slot is set at the corresponding position on the inner wall of the lamp head housing. The buckle structure is provided with a compression spring inside. One end of the spring is fixed to the inner wall of the buckle seat and the other end is connected to the buckle head. When the lithium battery compartment is inserted, the buckle head is compressed into the slot. After release, the spring force makes the buckle head automatically spring back and lock, realizing automatic reset. When pulling out, the buckle head is pressed to make it disengage from the slot to complete the unlocking operation. It automatically locks after insertion and unlocks by pressing when pulling out to prevent vibration and loosening. A sealing ring (7) is provided at the joint between the battery compartment (4) and the lamp head housing (1). The material is weather-resistant silicone, which has good waterproof and dustproof capabilities. The sealing ring is crimped to ensure overall sealing. The sealing ring is embedded in the annular groove at the front edge of the battery compartment, forming a press-fit with the corresponding flange inside the lamp head housing. After the battery compartment is inserted, the housing structure applies axial pressure to the sealing ring, with a pressing depth of approximately 60%-70% of the radial thickness of the sealing ring, ensuring tight contact and good resilience to prevent loosening and water leakage. During use, the operator pulls the front end of the battery compartment from the back of the lamp head housing, guiding it outwards along the slide rail. The slider and guide rail ensure smooth sliding. When the battery compartment is fully pulled out and passes the limit stop, the latch automatically disengages from the slot, unlocking the device. After replacing the battery, the battery compartment is pushed back along the original track. During this process, the slider re-enters the guide rail, and the front latch of the battery compartment automatically slides into the slot inside the housing under the action of the compression spring, completing the reset and locking. Simultaneously, the sealing ring and the housing contact surface are tightly pressed together, forming a complete seal to prevent dust and moisture from entering. The entire process can be completed by a single person, making it convenient and reliable.

[0021] Example 4: Figure 5 As shown, the back of the lamp head housing (1) is provided with multiple ventilation holes (8), each with a waterproof mesh cover to prevent rainwater and dust from entering; heat dissipation fins (9) are arranged in the corresponding areas of the ventilation holes, which are made of die-cast aluminum alloy and are integrated with the lamp head to effectively improve heat dissipation efficiency and prevent the lithium battery and control module from overheating. The ventilation holes (8) are evenly distributed in the upper middle area of ​​the back of the lamp head housing (1), with 3 to 5 holes on each side and a hole diameter of about 6 mm; the specific number and arrangement are determined according to the heat generation inside the lamp head and the structural space layout to ensure smooth air convection and not affect the installation of the internal structure; the waterproof mesh cover is installed in close contact with the ventilation holes, providing good dustproof and rainproof effects.

[0022] Example 5: A heat insulation layer (10) is provided between the control module (3) and the lithium battery compartment (4). The heat insulation layer (10) is made of porous ceramic fiber felt, which has high thermal resistance performance and a thickness of about 3mm. It is pasted between the bottom of the control module and the top of the battery compartment and fixed by high-temperature adhesive to form an effective heat isolation barrier, which significantly reduces the heat conduction from the module to the battery. This effectively reduces the impact of the control module's heat generation on the battery performance. In addition, the bottom of the lamp head housing (1) is provided with a mounting base plate (11) with screw holes, which facilitates the quick fixing of the lamp head to the top of the lamp post, realizing modular installation.

[0023] To achieve automatic power-off after the lithium battery compartment is removed, a power-off contact switch is installed at the end of the slide rail. The switch is fixed inside the lamp holder housing, corresponding to the rear of the battery compartment. A pressure plate is located at the bottom of the battery compartment. When the battery compartment is fully inserted, the pressure plate presses down, closing the contact switch and the circuit. When the battery compartment is pulled out to the critical position, the pressure plate releases, and the contact switch pops up, disconnecting the circuit, thus automatically cutting off the power and preventing short circuits or arcing during hot-swapping. The contact switch is a reed switch type, which is sensitive and highly reliable. The contact switch is connected to the main power circuit of the control module via a wire. When the switch is closed, the power circuit is connected, and the control module operates normally. When the contact switch is open, the power line is immediately cut off, forming a physical isolation. No software control is required, ensuring complete circuit disconnection. The structure is simple and highly reliable. The entire power-off circuit uses a low-voltage DC scheme, complying with outdoor lighting equipment safety regulations.

[0024] The above description is only a preferred embodiment of the present utility model. Any modifications and variations made by those skilled in the art to the structural details without departing from the concept of the present utility model shall fall within the protection scope of the present utility model.
