Safety warning device for semi-trailer

Abstract

This utility model provides a safety warning device for semi-trailer trucks, including a mounting base with a through groove on one side. Limiting plates are provided on both sides of the through groove, forming a mounting chamber between the limiting plates and the through groove. An insert block with a trapezoidal cross-section is slidably connected inside the mounting chamber, with one side extending to the outside of the mounting base and fixedly mounted with a warning light. A solar panel is installed at the center of the warning light. This utility model allows for tool-free installation and removal of the warning light through the sliding engagement of the trapezoidal insert block and the through groove, improving installation and removal efficiency compared to traditional bolt fixing. Furthermore, the use of magnets effectively attracts and fixes the insert block, ensuring its stability even on bumpy roads and preventing it from falling off. The solar panel at the center of the warning light converts solar energy into electrical energy, enabling the warning light to continue operating after the vehicle is turned off, solving the problem of power failure in traditional vehicle power supplies.

Description

Technical Field

[0001] This utility model belongs to the field of semi-trailer truck technology, and more specifically, it relates to a safety warning device for semi-trailer trucks. Background Technology

[0002] Semi-trailers are heavy-duty transport vehicles, and they come in many varieties, including 11-meter stake semi-trailers, 13-meter stake semi-trailers, and low-flatbed semi-trailers. Traditionally, semi-trailers use hazard lights when driving on highways, especially at night, as these lights play a crucial role in ensuring safe driving at night.

[0003] Traditional semi-trailer truck warning devices are mostly bolt-fixed, which requires tools and is time-consuming, making them difficult to install and remove quickly. After installation, they need to be connected to the truck battery for power, and cannot continue to work after the vehicle is turned off. In addition, long-term power consumption may lead to battery depletion. Therefore, in view of this, we have studied and improved the existing structure and its shortcomings to provide a safety warning device for semi-trailer trucks, in order to achieve a more practical value.

[0023] Example:

[0024] As attached Figure 1 To be continued Figure 4 As shown:

[0025] This utility model provides a safety warning device for semi-trailer trucks, including a mounting base 1. A through groove 3 is provided on one side of the mounting base 1. Limiting plates 2 are provided on both sides of the through groove 3, and an installation chamber is formed between the limiting plates 2 and the through groove 3. An insert 4 is slidably connected inside the installation chamber, and the cross-section of the insert 4 is trapezoidal. One side of the insert 4 extends to the outside of the mounting base 1 and is provided with an installation plate 13. A warning light 5 is installed on one side of the installation plate 13, and a solar panel 8 is installed at the center of the warning light 5.

[0026] The top dimension of the through groove 3 is larger than the bottom dimension. The trapezoidal guide structure of the through groove 3 can assist the insertion block 4 in quick positioning, avoid jamming caused by angular deviation during installation, improve the convenience of operation, and facilitate the rapid drainage of rainwater when it rains, thus improving the ease of use of the device.

[0027] The mounting base 1 has mounting slots on both sides of the slot, and magnets 6 are installed inside the mounting slots. The two sides of the plug 4 are made of metal that can be attracted by magnets 6, which can effectively attract and fix the plug 4. Combined with the trapezoidal structure of the through slot 3, it can resist the high-frequency vibration when the truck is traveling at high speed, and meet the needs of truck drivers for quick operation when loading, unloading and maintenance.

[0028] The warning light 5 has circular grooves on both sides, and fastening bolts 7 are connected inside the circular grooves. One end of the fastening bolts 7 is fastened to the mounting plate 13. The fastening bolts 7 are designed to be detachable, which makes it easy to replace the warning light 5 or the plug 4 separately, thus reducing maintenance costs.

[0029] The warning light 5 contains a battery, and a mounting slot is provided on one side of the warning light 5. A charging connector 9 is installed inside the mounting slot. A control board is installed inside the warning light 5, located on the side of the battery. The control board, charging connector 9, battery, and solar panel 8 are all interconnected by wires. A rubber protective cap 10 is installed on one side of the mounting slot to seal the charging connector 9. The solar panel 8 and the charging connector 9 work together to support dual charging via "solar energy + external power". At night or in weather conditions where solar energy cannot be absorbed, the solar panel 8 can be removed and recharged with a power bank to ensure uninterrupted power supply for the warning light 5. The rubber protective cap 10 is designed to resist the intrusion of rain or dust, extending the service life of the device.

[0030] The mounting base 1 has mounting holes 11 at each of its four corners. The mounting holes 11 support bolt fixing to different positions such as the rear, side, and roof of the truck to form a continuous warning strip and increase the warning range of large trucks.

[0031] The mounting base 1 has reflective strips 12 affixed to both sides away from the warning light 5. The reflective strips 12 reflect light under the illumination of the light, forming a dual warning of "active light emission + passive reflection" with the warning light 5. The warning effect can still be achieved when the warning light 5 is taken out for charging, thus improving driving safety.

[0032] The working principle of this embodiment:

[0033] When using the warning device, first install the mounting base 1 at the designated position on the semi-trailer truck. Then, slide the insert 4 into the through groove 3. Because the through groove 3 has limiting plates 2 on both sides, forming a trapezoidal fit with the insert 4, and the top of the through groove 3 is larger than the bottom, the insert 4 automatically locks in place due to the trapezoidal wedge effect. At the same time, the metal material on both sides of the insert 4 attracts the magnet 6 in the mounting groove, achieving a double locking of mechanical locking and magnetic fixation, thus completing the installation. Meanwhile, reflective strips 12 are attached to both sides of the mounting base 1, which will illuminate the vehicle under the headlights. The solar panel 8 is installed in the center of the warning light 5. During the day, it absorbs light energy and converts it into electrical energy, which is stored in the battery through the control board. At night or when there is insufficient light, the battery supplies power to the warning light 5 to achieve continuous warning. When the battery is depleted, the plug 4 is pulled out and taken to the cab. Then, the rubber protective cap 10 can be lifted and the battery can be charged by connecting an external power source (such as a truck charger or power bank) through the charging connector 9, thereby ensuring its range.

[0034] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
