[0003] The existing structure of LED illuminated door handles still has the following problems when in use: On the one hand, most illuminated door handles lack intelligent sensing and adjustment of lighting functions, either always on, resulting in high energy consumption, or the sensing logic is simple and cannot flexibly adjust the brightness or on / off state according to ambient light and usage scenarios (such as the distance of people approaching); on the other hand, the integration of the light-emitting components with the handle body is insufficient, the light diffusion effect is poor, the lighting range is limited, and power replacement and component maintenance are not convenient enough, affecting the user experience and service life. Utility Model Content

[0004] (a) Technical problems to be solved.

[0005] To address the shortcomings of existing technologies, this utility model provides a structure for an LED illuminated door handle, which includes an intelligent sensing and light diffusion mechanism, as well as a main structure that is easy to assemble and maintain. This solves the problems of lack of intelligent lighting adjustment, poor light diffusion effect, and inconvenient component maintenance mentioned in the background technology.

[0006] (ii) Technical solution.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a structure for an LED light-emitting door handle, comprising a handle body, a light-emitting mechanism, a washer, and a foot pad.

[0008] The handle body includes a U-shaped handle frame. Grooves are formed in the middle of both sides of the top of the U-shaped handle frame. A mounting hole is formed in the center of the bottom wall of each groove for fasteners to securely connect the handle to the external structure. An assembly groove is formed in the center of the top of the U-shaped handle frame, providing installation space for the core components of the light-emitting mechanism. Mounting slots are formed at both ends of the assembly groove to accommodate strip lamp holders and LED beads. A top cover is installed at the opening of the top of the groove for protection and sealing. Lens-type glass plates are fixedly installed on the outer walls of both ends of the U-shaped handle frame, located at the opening of the mounting slots, to diffuse the light from the LED beads, improving the lighting range and uniformity.

[0009] The light-emitting mechanism includes an energy storage battery pack, a charging interface, a controller, a sensor, and a strip lamp holder disposed within the mounting slot. Each of the two strip lamp holders has multiple LED beads at one end, providing sufficient illumination. The sensor is located on top of the controller and includes a distance sensor and a light sensor, capable of detecting ambient light levels and the distance between a person and the handle. The charging interface is located on top of the energy storage battery pack for easy charging. The controller, sensor, charging interface, and strip lamp holder are all electrically connected to the energy storage battery pack for power supply and signal control. The top cover has a charging interface adapter slot for the charging interface and a sensor adapter slot for the sensor, allowing the charging interface and sensor to interact with the outside through the slots on the top cover.

[0010] The washer is fixedly installed on the outside of the mounting hole opening on the bottom wall of the groove, serving as a buffer and seal; the foot pads are fixedly installed at the bottom of both ends of the U-shaped handle bracket, enhancing the stability and anti-slip properties of the handle after installation.

[0011] As a further improvement of this utility model, the lens-type glass plate is fixed to the outer wall of the U-shaped handle frame by a snap-fit ​​connection, which is convenient for installation and disassembly, and can effectively diffuse the light emitted by the LED beads, so that the light can illuminate the surrounding area more evenly.

[0012] As a further improvement of this utility model: the strip lamp holder is a long strip structure adapted to the shape of the inner side of the mounting groove, ensuring that the strip lamp holder can be stably assembled in the mounting groove; multiple LED beads are arranged at uniform intervals on the strip lamp holder, making the lighting more uniform and the range wider.

[0013] As a further improvement of this utility model: the controller and the energy storage battery pack are fixedly installed on the bottom wall of the assembly slot, and the installation is stable; the controller has a preset control program, which can intelligently control the LED beads to turn on, turn off and adjust the brightness according to the distance signal and light signal detected by the sensor, so as to achieve energy-saving lighting that is suitable for different scenarios.

[0014] As a further improvement of this utility model: through holes are provided between the upper and lower side walls of the foot pad corresponding to the mounting holes, so that fasteners can pass through to fix the handle; and the bottom of the foot pad is provided with anti-slip teeth to increase the friction between the foot pad and the mounting surface, improve the stability of the handle after installation, and prevent loosening.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, by setting up sensors with distance sensing probes and light sensing probes, and in conjunction with a controller with a preset control program, the LED beads can be intelligently controlled to turn on, turn off, and adjust their brightness according to the ambient light intensity and the distance between the person and the handle. For example, when the light is dim and someone approaches the handle, the LED beads are automatically turned on and adjusted to a suitable brightness, which not only meets the lighting needs but also avoids the energy waste caused by constant lighting, thus realizing intelligent and energy-saving lighting control. At the same time, the diffusion effect of the lens-type glass plate on the light of the LED beads effectively improves the lighting range and light uniformity, making the lighting assistance effect better.

[0016] 2. In this utility model, by integrating the various components of the light-emitting mechanism into the assembly groove and installation groove of the handle body, and by using convenient snap-fit ​​connections for the top cover, lens glass plate, etc., the integration of the light-emitting components with the handle body is high. This not only facilitates assembly but also makes it convenient for subsequent maintenance or replacement of the energy storage battery pack, LED beads, etc. In addition, the anti-slip serrations on the bottom of the foot pads enhance the stability of the handle installation, while the gaskets improve the sealing and cushioning of the installation point. The overall structure is more practical and reliable. Attached Figure Description
