Description

Technical Field

[0001] This utility model belongs to the field of truck parts technology, specifically a truck headlight. Background Technology

[0002] Truck headlights are generally used for illumination and warning purposes when trucks are driving at night. Currently, existing truck headlights typically consist of a lamp, a bracket, and a transparent lampshade. When in use, the light from the lamp illuminates the environment through the transparent lampshade. However, during vehicle operation, such as when passing through muddy sections, the transparent lampshade is easily covered with dirt, affecting the lighting effect. Furthermore, it is difficult for drivers to get out of the vehicle to clean it at high speeds, impacting its usability. Moreover, during the day when the headlights are not needed, the transparent lampshade is easily damaged by external forces. Therefore, researching a new truck headlight to solve these problems is of great significance. Utility Model Content

[0027] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0028] like Figure 1-5 As shown, this utility model provides a technical solution: a truck headlight, including a truck light component 1, and a cleaning component 2 is assembled in front of the truck light component 1;

[0029] The truck light assembly 1 includes a headlight housing 11, a headlight lens bracket 12, a headlight lens assembly 13, an LED circuit board 14, a circuit board bracket 15, a headlight trim frame 16, a lens trim frame 17, a headlight lens trim 18, and a lamp cover 19. The headlight lens bracket 12 is installed in the headlight housing 11, which serves to accommodate and fix the entire assembly. The headlight lens assembly 13 is installed on the headlight lens bracket 12. The LED circuit board 14 is installed in the headlight housing 11 through the circuit board bracket 15, which stably mounts the LED circuit board 14. In the headlight housing 11, the headlight trim frame 16 is installed in front of the headlight housing 11, the lamp cover 19 is installed in front of the headlight trim frame 16, and the lens trim frame 17 is installed in the headlight trim frame 16. The headlight trim frame 16 can fix the lens trim frame 17 to maintain stability. At the same time, the headlight trim frame 16 can seal the headlight housing 11. Secondly, the lens trim frame 17 can limit the headlight lens assembly 13 to maintain the firmness of the headlight lens assembly 13. The headlight lens assembly 13 is set in the lens trim frame 17, and the headlight lens trim 18 is installed in front of the lens trim frame 17.

[0030] The cleaning component 2 includes a guide structure 21, which includes two fixing members 211. The two fixing members 211 are fixedly connected to the front of the lampshade 19. A horizontal plate 212 is fixedly connected to the front of the two fixing members 211. Multiple sliding sleeves 213 are fixedly connected to the horizontal plate 212. A guide rod 27 slides through the sliding sleeves 213, allowing it to slide smoothly. The guide rod 27 can also smoothly connect to the baffle 210 after passing through the sliding sleeves 213. Furthermore, the guide rod 27 descends to the front of the lampshade 19, providing protection for the lampshade 19. Two support members 24 are fixedly connected to the top of the horizontal plate 212. The guide structure 21 is located on the upper side in front of the lampshade 19. A drive structure 22 is installed on one side of the guide structure 21. The drive structure 22 includes a bracket 222, which can fix the motor 221 to maintain its stability. The bracket 222 is fixedly connected to one side of the horizontal plate 212. The motor 221 is installed above the bracket 222. The motor 221 drives the lead screw 23 to rotate, so that the lead screw 23 can drive the nut 25 to move. The output shaft of the motor 221 is fixedly connected to the lead screw 23. One end of the drive structure 22 is fixedly connected to the lead screw 23. The threads of the lead screw 23 are arranged in opposite directions from the middle to both ends. The threads of the lead screw 23 are arranged in opposite directions, allowing the lead screw 23 to drive the nuts 25 to achieve relative and opposite movements. This enables the connecting rod 262 to unfold smoothly. The lead screw 23 is rotatably mounted on two support members 24 via two bearings. The lead screw 23 can maintain stable rotation through the bearings, allowing the lead screw 23 to stably drive the nut 25. Two nuts 25 are threaded onto the lead screw 23, and each nut 25 is connected to a connecting rod structure 26. The connecting rod structure 26 includes two hinge brackets 261, which are hinged to both ends of the connecting rod 262 via pins. The connecting rod 262 can move smoothly through the pins, allowing the connecting rod 262 to rotate smoothly. The horizontal bar 28 moves up and down. Two hinged frames 261 are fixedly connected to the horizontal bar 28 and the nut 25 respectively. The horizontal bar 28 is connected above the two connecting rod structures 26. Multiple guide rods 27 are fixedly connected below the horizontal bar 28. The bottom ends of the multiple guide rods 27 pass through the guide structure 21 and are fixedly connected to the baffle 210. A sponge layer 29 is fixedly connected behind the baffle 210. The sponge layer 29 is attached to the front of the lampshade 19. A squeezing roller 3 is fixed on the lower side of the front of the lampshade 19. When the sponge layer 29 contacts the squeezing roller 3 downward, the sponge layer 29 is squeezed and deformed by the squeezing roller 3, which facilitates the removal of moisture from the sponge layer 29.

[0031] The working principle of this utility model is as follows: During cleaning, the motor 221 drives the lead screw 23 to rotate, and the lead screw 23 drives the two nuts 25 to move away from each other. The nuts 25 drive the connecting rod 262 to spread to both sides through the hinge frame 261, and the connecting rod 262 drives the horizontal bar 28 to move downward. The horizontal bar 28 drives the guide rod 27 to move downward, and the guide rod 27 can drive the sponge layer 29 to move downward. The sponge layer 29 cleans the lamp cover 19 downward. When the sponge layer 29 contacts the squeezing roller 3, the squeezing roller 3 squeezes the sponge layer 29 to drain water. After cleaning, the motor 221 reverses, and the sponge layer 29 returns to its original position.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
