Description

Technical Field

[0001] This utility model relates to the field of road emergency signal light technology, and in particular to a USB road emergency signal light with waterproof function. Background Technology

[0002] Emergency traffic lights are indispensable for ensuring road traffic safety, especially in scenarios such as nighttime, inclement weather, road construction, traffic accidents, or emergency repairs. Their core function is to provide highly visible warning or guidance signals to alert drivers to changes in road conditions, effectively avoid potential dangers, and ensure the safety of workers and passing vehicles.

[0003] Currently, most road emergency traffic lights on the market rely on dry cell batteries for power. While this power supply method is simple in structure and easy to implement, dry cell batteries have limited capacity and their power is quickly depleted under continuous high-intensity operation. Once the battery is depleted, the traffic light stops working, loses its warning function, and poses a serious safety hazard. In practical applications, especially in remote areas or emergency situations, it may not be possible to immediately obtain a matching spare battery. Frequent battery replacements are not only cumbersome and require manual intervention, but also increase maintenance costs and management burden.

[0004] To address the battery life issue of dry cell batteries, alternative solutions using USB interfaces for power supply have emerged in the market. Theoretically, these solutions can provide longer-lasting power using power banks, mobile phones, or solar panels combined with power banks. However, road emergency signal lights are constantly exposed to the outdoor environment and must meet high levels of dust and water resistance to withstand harsh conditions such as rain, sand, mud, road splashes, and corrosion from de-icing agents in winter.

[0005] Standard USB interfaces (Type-A, Type-C, Micro-USB, etc.) are not designed for high-protection environments. Their exposed metal contacts and open slot structure are highly susceptible to dust accumulation and liquid intrusion, leading to poor contact, short circuits, oxidation and corrosion, and ultimately failure.

[0006] To safely and reliably use USB power in road emergency traffic lights, a dedicated, reliable dustproof and waterproof structure must be designed for the USB interface. This results in a significant increase in cost, structural complexity, and reduced ease of maintenance.

[0007] In summary, the existing power supply methods for road emergency signal lights have obvious shortcomings: traditional dry cell battery power supply relies on specific battery models, has limited battery life, is inconvenient to replace, and has high long-term costs; while the introduced USB power supply method can improve battery life, it is forced to add additional dustproof and waterproof structures due to interface protection problems, which increases costs and complexity. Utility Model Content

[0008] This utility model addresses the shortcomings of existing technologies by providing a waterproof USB road emergency signal light. This waterproof USB road emergency signal light integrates the USB interface into the battery compartment, and the battery compartment cover has a waterproof structure. This meets the waterproof requirements for both dry battery power and USB interface power, eliminating the need for a separate dustproof and waterproof structure for the USB interface and reducing costs.

[0009] To solve the aforementioned technical problems, this utility model provides a waterproof USB road emergency signal light, comprising a signal light body, a battery compartment on the signal light body, a detachable cover connected to the battery compartment, a light panel on the signal light body, a USB interface on the light panel, a socket aligned with the USB interface on the inner wall of the battery compartment, an elastic sealing ring on the cover that presses against the side wall of the battery compartment to seal the battery compartment, and a first notch for a USB power cable to pass through on the side of the battery compartment and / or the elastic sealing ring. When the cover is closed, the sealing ring blocks the first notch or the USB power cable is pressed to block the first notch. This road emergency signal light can be powered not only by dry cell batteries inserted into the battery compartment but also by a USB power cable inserted into the USB interface, powered by a power bank or mobile phone. When powered by dry cell batteries, the elastic sealing ring on the cover seals the first notch and keeps the battery compartment sealed after the cover is closed. When powered by a USB power cable, the elastic sealing ring can deform, allowing the cover to close even when the USB power cable passes through the first notch, and the deformed ring still ensures a tight seal. This satisfies the waterproof requirements for both dry cell battery and USB power supply, eliminating the need for a separate dustproof and waterproof structure for the USB interface and reducing costs.

[0010] In the above technical solution, preferably, a positioning groove is provided on the side of the battery compartment, and a limiting part is provided on the opening side of the positioning groove. A bending elastic part is provided on the side of the compartment cover. After the bending elastic part is inserted into the elastic positioning groove, it is positioned by the limiting part. This structure facilitates the opening and closing of the compartment cover. Simply pressing the bending elastic part can disengage it from the limiting part, and it is easy to assemble and disassemble.

[0011] In the above technical solution, preferably, the bending elastic part is provided with a cable outlet groove to avoid interference between the USB power cable and the bending elastic part on the cover.

[0012] In the above technical solution, preferably, the cable outlet slot is aligned with the first notch. This structure allows the USB power cable to extend straight between the cable outlet slot and the first notch, facilitating the insertion of the USB power cable into the cable outlet slot and the first notch.

[0013] In the above technical solution, preferably, an insert block is provided on the side of the compartment cover opposite to the bending elastic part, and a slot matching the insert block is provided on the main body of the signal light. When the compartment cover is closed, the insert block is inserted into the slot, and then the bending elastic part is positioned in the positioning groove, making the positioning of the compartment cover more reliable.

[0014] In the above technical solution, preferably, the outer shell of the signal light body is provided with a second notch aligned with the first notch. This also allows the USB power cable to extend straight between the first and second notches, facilitating its insertion into the first and second notches.

[0015] In the above technical solution, preferably, a switch is provided on the lamp panel, and a switch button aligned with the switch is provided on the top of the signal light body. This structure allows the switch on the lamp panel to be activated by pressing the switch button, facilitating the switching of the signal light.

[0016] Compared with existing technologies, this invention has the following advantages: This road emergency signal light can be powered not only by dry cell batteries inserted into the battery compartment, but also by a USB power cable inserted through a USB interface, powered by a power bank or mobile phone. When powered by dry cell batteries, the elastic sealing ring on the compartment cover can seal the first gap and seal the battery compartment after the cover is closed; when powered by a USB power cable, because the elastic sealing ring can deform, the cover can still be closed even when the USB power cable passes through the first gap, and the deformation of the elastic sealing ring can still ensure the battery compartment is sealed. Therefore, it meets the waterproof requirements for both dry cell battery power and USB interface power, eliminating the need for a separate dustproof and waterproof structure for the USB interface, thus reducing costs.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: See below Figures 1 to 6 A waterproof USB road emergency signal light includes a signal light body 1, a battery compartment 2 on the signal light body 1, a cover 3 detachably connected to the battery compartment 2, a light panel 4 on the signal light body 1, a USB interface 5 on the light panel 4, a socket 6 on the inner wall of the battery compartment 2 aligned with the USB interface 5, an elastic sealing ring 7 on the cover 3 that presses against the side wall of the battery compartment 2 to seal the battery compartment 2, and a first notch 8 on the side of the battery compartment 2 and / or the elastic sealing ring 7 for the USB power cable to pass through. When the cover 3 is closed, the elastic sealing ring 7 blocks the first notch 8 or the USB power cable is pressed to block the first notch 8.

[0024] In this embodiment, the battery compartment 2 has a first notch 8 on its side.

[0025] In other embodiments, the first notch 8 may also be provided on the elastic sealing ring 7, or the side of the battery compartment 2 and the elastic sealing ring 7 are provided with aligned first notches 8, which are misaligned and sealed after the compartment cover 3 is closed, or are kept sealed by the compression deformation of the elastic sealing ring 7 when the USB power cable passes through.

[0026] In this embodiment, to facilitate the positioning of the compartment cover 3 and the elastic sealing ring 7, an annular groove 31 is provided on the outer periphery of the positioning compartment cover 3, and the elastic sealing ring 7 is fitted inside the annular groove 31.

[0027] This type of road emergency signal light can be powered not only by dry cell batteries inserted into the battery compartment 2, but also by a USB power cable inserted into the USB interface 5, via a power bank or mobile phone. When powered by dry cell batteries, the elastic sealing ring 7 on the cover 3 seals the first notch 8, thus sealing the battery compartment 2. When powered by the USB power cable, because the elastic sealing ring 7 is deformable, the cover 3 can still close even when the USB power cable passes through the first notch 8, and the deformed elastic sealing ring 7 still ensures a seal in the battery compartment 2. This satisfies the waterproof requirements for both dry cell battery power and USB interface 5 power supply, eliminating the need for a separate dustproof and waterproof structure for the USB interface 5, thus reducing costs.

[0028] In this embodiment, a positioning groove 9 is provided on the side of the battery compartment 2, and a limiting part 10 is provided on the opening side of the positioning groove 9. A bending elastic part 11 is provided on the side of the compartment cover 3. After the bending elastic part 11 is inserted into the elastic positioning groove 9, it is positioned by the limiting part 10. This structure facilitates the opening and closing of the compartment cover 3. The bending elastic part 11 can be disengaged from the limiting part 10 simply by squeezing the bending elastic part 11, and it is easy to assemble and disassemble.

[0029] In this embodiment, the bending elastic part 11 is provided with a cable outlet groove 12 to avoid interference between the USB power cable and the USB power cable. This structure can prevent the bending elastic part 11 on the cover 3 from interfering with the USB power cable.

[0030] In this embodiment, the cable outlet slot 12 is aligned with the first notch 8. This structure allows the USB power cable to extend straight between the cable outlet slot 12 and the first notch 8, facilitating the insertion of the USB power cable into the cable outlet slot 12 and the first notch 8.

[0031] In this embodiment, an insert 16 is provided on the side of the cover 3 opposite to the bending elastic part 11, and a slot 17 matching the insert 16 is provided on the signal lamp body 1. When the cover is closed, the insert is inserted into the slot 17, and then the bending elastic part 11 is placed into the positioning groove 9 for positioning, making the positioning of the cover 3 more reliable.

[0032] In this embodiment, the outer shell of the signal light body 1 is provided with a second notch 13 aligned with the first notch 8. This also allows the USB power cable to extend straight between the first notch 8 and the second notch 13, facilitating its insertion into the first notch 8 and the second notch 13.

[0033] In this embodiment, a switch 14 is provided on the lamp panel 4, and a switch button 15 aligned with the switch 14 is provided on the top of the signal light body 1. This structure allows the switch 14 on the lamp panel 4 to be activated by pressing the switch button 15, facilitating the switching on and off of the signal light.

[0034] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
