[0002] Headlights, also known as headlamps, are lighting devices mounted on both sides of the front of a car for nighttime driving. They are available in two-lamp and four-lamp systems. The effectiveness of headlights directly impacts driving maneuverability and traffic safety at night.

[0003] In actual industrial production, headlights tend to heat up after prolonged use, so a heat dissipation structure is usually installed for them. However, traditional headlight heat dissipation structures often use ventilation holes, allowing air to enter directly through these holes to cool the headlights. Since air often contains dust, dust inevitably accumulates around the headlights as air enters directly, which can easily affect the headlights. This results in inadequate dust filtration during headlight heat dissipation, severely impacting the protective measures for headlight heat dissipation. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0029] Please see Figure 1-4 As shown, this utility model is a headlight with a heat dissipation structure, comprising:

[0030] Lampshade 1, with mounting plate 2 fixedly connected to one side of lampshade 1;

[0031] The protective mechanism 3 includes a frame plate 31 fixedly connected to one side of the mounting plate 2, a filter plate 32 provided on one side of the frame plate 31, a fixing plate 33 provided on the other side of the frame plate 31, a side rod 35 fixedly connected to the other side of the frame plate 31, a fan 36 fixedly installed inside the frame plate 31, a fixing block 37 fixedly connected to one side of the filter plate 32, a locking block 38 fixedly connected to one side of the fixing plate 33, a connecting rod 39 fixedly connected to the other side of the fixing plate 33, a spring 310 sleeved on the outer surface of the connecting rod 39, and a bottom block 311 fixedly connected to one end of the connecting rod 39.

[0032] The locking mechanism 34 includes a fixed plate 341 on one side of the fixed plate 33, a rotating block 342 on one side of the side rod 35, a threaded rod 343 fixedly connected to one side of the rotating block 342, a sleeve rod 344 fixedly connected to one side of the fixed plate 341, and a limit block 345 fixedly connected to one end of the threaded rod 343.

[0033] The protective mechanism 3 is used to protect the heat dissipation of the headlight inside the lamp cover 1 and the mounting plate 2. Two fans 36 for air supply and exhaust are respectively installed on the frame plate 31 to ensure good air circulation inside the lamp cover 1 and prevent the heat inside the lamp cover 1 from being unable to dissipate properly. A filter plate 32 is connected to one side of each of the two fans 36 to filter dust and prevent dust from entering the lamp cover 1 and affecting the headlight. The locking mechanism 34 is used to lock and reinforce the filter plate 32 after it is fixed to the frame plate 31, to prevent the filter plate 32 from accidentally separating from the frame plate 31 and to improve the stability of the connection between the filter plate 32 and the frame plate 31.

[0034] The frame plate 31 has a mounting groove on one side that matches the filter plate 32, and the fan 36 has an insertion hole on one side that matches the fixing block 37.

[0035] The filter plate 32 is installed and fixed to the frame plate 31 through the mounting groove. The fixing block 37 is inserted between the frame plate 31 and the fan 36 through the insertion hole to avoid the filter plate 32 from failing to be installed properly.

[0036] One side of the locking block 38 slides through one side of the frame plate 31, and one side of the fixing block 37 is provided with a locking hole that matches the locking block 38.

[0037] The locking block 38 is used to fix the fixing block 37. The locking block 38 passes through the frame plate 31 and is inserted into the fixing block 37 through the locking hole, so that the filter plate 32 can be fixed on the frame plate 31 by the locking block 38 and the fixing block 37.

[0038] One end of the connecting rod 39 slides through one end of the side rod 35, and the inside of the side rod 35 is provided with a groove that matches the bottom block 311;

[0039] By creating a groove, the bottom block 311 can slide inside the side rod 35, preventing the connecting rod 39 from being unable to move properly on the side rod 35.

[0040] One end of the spring 310 is welded to one side of the inner wall of the inner groove of the side rod 35, and the other end of the spring 310 is welded to one side of the bottom block 311.

[0041] Spring 310 provides sufficient elastic force, and the base block 311 can actively restore its position after being moved by utilizing the elastic force of spring 310.

[0042] Working principle: The frame plate 31 is fixed on the mounting plate 2. Two fans 36, one for air supply and one for air exhaust, are installed inside the frame plate 31. Filter plates 32 are installed on each of the two fans 36. Fixing blocks 37 on the filter plates 32 are inserted into the fans 36 and the frame plate 31, pushing the filter plates 32 to move. One side of the locking block 38 is sloped. As the fixing block 37 is inserted, after the fixing block 37 contacts the locking block 38, the locking block 38 actively moves due to the movement of the fixing block 37, and in the process, it drives the fixing plate 33 to move. The connecting rod 39 gradually moves out of the side rod 35 along with the movement of the fixing plate 33. The bottom block 311 gradually moves inward along with the movement of the connecting rod 39. As the side rod 35 moves internally, the spring 310 contracts due to the movement of the bottom block 311, until the filter plate 32 can no longer move. At this point, the locking block 38 corresponds to the locking hole on the fixing block 37, and the spring 310 is no longer affected by the force. Its shape gradually returns to its original state, and in the process of restoring its shape, it drives the bottom block 311 to reset. The connecting rod 39 follows the movement of the bottom block 311 and re-inserts into the side rod 35. The fixing plate 33 moves with the movement of the connecting rod 39 and drives the locking block 38 to move. The locking block 38 inserts into the fixing block 37 and fixes it. The filter plate 32 is fixed on the frame plate 31 by the fixing block 37 and the locking block 38.

[0043] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0044] A groove adapted to the fixed plate 341 is provided on one side of the fixed plate 33, and one end of the sleeve rod 344 slides through one side of the inner wall of the groove. A sliding hole adapted to the sleeve rod 344 is provided on one end of the connecting rod 39 and one side of the bottom block 311.

[0045] A groove is provided so that the fixing plate 341 can overlap with the fixing plate 33, and a sliding hole is provided so that the sleeve rod 344 can slide normally inside the connecting rod 39 and the bottom block 311.

[0046] One end of the threaded rod 343 passes through one side of the side rod 35 via a bearing. One end of the sleeve rod 344 is provided with a threaded hole that matches the thread on the threaded rod 343, and the other end of the sleeve rod 344 is provided with a limiting groove that matches the limiting block 345.

[0047] A threaded hole is provided so that the sleeve rod 344 can move normally during the rotation of the threaded rod 343. A limiting groove is provided so that the limiting block 345 can move normally inside the sleeve rod 344 and be limited.

[0048] Working principle: After the filter screen plate 32 and the frame plate 31 are fixed together by the locking block 38 and the fixing block 37, the rotating block 342 is rotated. During the rotation of the rotating block 342, the threaded rod 343 is rotated. As the threaded rod 343 rotates, the sleeve rod 344 gradually moves and drives the fixing plate 341 to move. The fixing plate 341 gradually moves closer to the fixing plate 33 until the rotating block 342 can no longer rotate. The fixing plate 341 contacts the fixing plate 33 and fixes it. The fixing plate 33 remains in a fixed position. The locking block 38 is stably inserted into the fixing block 37, and the filter screen plate 32 and the frame plate 31 are locked and fixed.
