Description

Technical Field

[0001] This utility model belongs to the field of LED aluminum substrate technology, specifically relating to a high-efficiency heat dissipation composite LED aluminum substrate. Background Technology

[0002] In the lighting field, the application of LED lighting products is attracting worldwide attention. LEDs have many advantages such as high luminous efficiency, long lifespan, energy saving, and environmental protection, and are increasingly widely used in many fields.

[0003] Chinese patent publication number CN 217464346 U discloses a high-efficiency heat dissipation composite LED aluminum substrate, including a mounting plate. The top of the mounting plate has a groove, and an LED aluminum substrate body is fixedly mounted in the groove. A heat-conducting plate is fixedly mounted at the bottom of the LED aluminum substrate body, and a heat-conducting cavity is formed in the heat-conducting plate.

[0004] However, the current high-efficiency heat dissipation composite LED aluminum substrate has the following problems: it cannot allow the heat of the LED aluminum substrate to be blown out through the ventilation port, it cannot remove the dust on the top of the mounting plate, and it cannot achieve the cleaning effect, which makes the heat dissipation device unable to work smoothly. Therefore, we propose a high-efficiency heat dissipation composite LED aluminum substrate. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency heat dissipation composite LED aluminum substrate, which can solve the problems of the inability to blow away the heat of the LED aluminum substrate through the ventilation holes, the inability to scrape off the dust on the top of the mounting plate, the inability to achieve a cleaning effect, and the inability of the heat dissipation device to work properly.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A high-efficiency heat dissipation composite LED aluminum substrate includes a support leg and a mounting plate. The mounting plate is fixedly connected to the bottom of the support leg. A ventilation opening is passed through the top of the mounting plate. An LED aluminum substrate is snapped into the bottom of the mounting plate. A heat dissipation device is provided at the bottom of the mounting plate. The heat dissipation device includes a motor, which is fixedly passed through the top of the mounting plate. A rotating shaft is fixedly connected to the end of the motor's output shaft. A rotating plate is fixedly connected to the circumferential surface of the rotating shaft. A round shaft passes through the top of the rotating plate.

[0008] A gear is fixedly connected to the circumferential surface of the circular shaft, a fixing ring is fixedly connected to the circumferential surface of the circular shaft, a fan blade is fixedly connected to the circumferential surface of the fixing ring, a support rod is fixedly connected to the bottom of the mounting plate, and a gear plate is fixedly connected to the bottom of the support rod.

[0009] The gear meshes with the gear disk, the gear is located at the top of the rotating plate, and there are two support rods that are symmetrical to each other along the vertical central axis at the bottom of the mounting plate.

[0010] A cleaning device is provided on the top of the mounting plate. The cleaning device includes a half gear, which is fixedly connected to the circumferential surface of the rotating shaft. A sliding groove is passed through the top of the mounting plate, and a spring is fixedly connected to the sliding groove.

[0011] A slider is fixedly connected to the end of the spring away from the inner wall of the groove. A rack is fixedly connected to the side of the slider, and a scraper is fixedly connected to the top of the slider.

[0012] The slider has an L-shaped side cross-section and is slidably connected to the inner wall of the groove.

[0013] The half gear meshes with the rack, the side section of the scraper is U-shaped, and the scraper is slidably connected to the top of the mounting plate.

[0014] The technical effects achieved by this utility model are as follows:

[0015] This invention utilizes the interplay of components such as gears, a fixed ring, fan blades, and a circular shaft. When the gear moves along with the circular shaft, it rotates counterclockwise due to the influence of the gear disc, forcing the circular shaft to rotate counterclockwise as well. When the circular shaft rotates counterclockwise, it forces the fixed ring, which is fixed to the circumference of the circular shaft, to rotate counterclockwise, thereby causing the fan blades to rotate counterclockwise. This achieves the effect of storing air and blowing the heat from the LED aluminum substrate out through the ventilation opening, thus achieving heat dissipation and improving the stability of the LED aluminum substrate.

[0016] This invention utilizes the interplay of components such as a half-gear, rack, slide, and spring to achieve a situation where, when the half-gear rotates continuously, it no longer meshes with the rack, causing the rack to lose its force. Consequently, the slider and spring lose their force, and the spring uses its own elasticity to reset the slider and rack. This allows the scraper fixed to the top of the slider to scrape back and forth on the top of the mounting plate, removing dust and achieving a cleaning effect. This ensures that the heat dissipation device can function smoothly. Attached Figure Description

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figure 1-5 As shown, a high-efficiency heat dissipation composite LED aluminum substrate includes a support leg 1 and a mounting plate 2. The mounting plate 2 is fixedly connected to the bottom of the support leg 1. A ventilation opening 3 is passed through the top of the mounting plate 2. An LED aluminum substrate 4 is snapped into the bottom of the mounting plate 2. A heat dissipation device 5 is provided at the bottom of the mounting plate 2. The heat dissipation device 5 includes a motor 51, which is fixedly passed through the top of the mounting plate 2. A rotating shaft 52 is fixedly connected to the end of the output shaft of the motor 51. A rotating plate 53 is fixedly connected to the circumferential surface of the rotating shaft 52. A circular shaft 54 ​​passes through the top of the rotating plate 53.

[0026] A gear 55 is fixedly connected to the circumferential surface of the round shaft 54, a retaining ring 56 is fixedly connected to the circumferential surface of the round shaft 54, a fan blade 57 is fixedly connected to the circumferential surface of the retaining ring 56, a support rod 58 is fixedly connected to the bottom of the mounting plate 2, and a gear disk 59 is fixedly connected to the bottom of the support rod 58. The support rod 58 can support the gear disk 59.

[0027] Gear 55 meshes with gear disk 59. Gear 55 is located on the top of rotating plate 53. There are two support rods 58, which are symmetrical about each other along the vertical central axis of the bottom of mounting plate 2. Gear 55 meshes with gear disk 59, which enables gear 55 to rotate counterclockwise.

[0028] According to the above structure, when the operator turns on the external power, the motor 51 starts to operate, forcing the rotating shaft 52 to rotate counterclockwise, which in turn drives the rotating plate 53 to rotate counterclockwise. When the rotating plate 53 rotates counterclockwise, it drives the circular shaft 54 ​​to rotate counterclockwise along with the rotating plate 53, causing the gear 55 fixed on the circumference of the circular shaft 54 ​​to rotate counterclockwise. Since the gear 55 meshes with the gear disk 59, when the gear 55 moves together with the circular shaft 54, the gear 55 is affected by the gear disk 59 and rotates counterclockwise, forcing the circular shaft 54 ​​to rotate counterclockwise as well. When the circular shaft 54 ​​rotates counterclockwise, it forces the fixing ring 56 fixed on the circumference of the circular shaft 54 ​​to rotate counterclockwise, thereby causing the fan blade 57 to rotate counterclockwise, achieving the effect of wind storage, blowing the heat of the LED aluminum substrate 4 out through the ventilation port 3, achieving the effect of heat dissipation, and improving the stability of the LED aluminum substrate 4.

[0029] like Figure 1-5 As shown, a cleaning device 6 is provided on the top of the mounting plate 2. The cleaning device 6 includes a half gear 61, which is fixedly connected to the circumferential surface of the rotating shaft 52. A sliding groove 62 passes through the top of the mounting plate 2, and a spring 63 is fixedly connected to the sliding groove 62. The half gear 61 can move with the movement of the rotating shaft 52.

[0030] A slider 64 is fixedly connected to the end of the spring 63 away from the inner wall of the slide groove 62. A rack 65 is fixedly connected to the side of the slider 64, and a scraper 66 is fixedly connected to the top of the slider 64. When the spring 63 loses its force, it can drive the slider 64 to reset.

[0031] The side section of the slider 64 is set in an L shape. The slider 64 is slidably connected to the inner wall of the groove 62. When the slider 64 is subjected to force and slides on the inner wall of the groove 62, it can drive the rack 65 to move.

[0032] The half gear 61 meshes with the rack 65, the side section of the scraper 66 is set in a U shape, the scraper 66 is slidably connected to the top of the mounting plate 2, and the scraper 66 can stick to the top of the mounting plate 2 to scrape away dust.

[0033] According to the above structure, due to long-term use of this component, dust will accumulate on the top of the mounting plate 2. In order to prevent dust from clogging the ventilation vent 3, when the rotating shaft 52 rotates counterclockwise, it forces the half gear 61 to rotate counterclockwise, forcing the rack 65 to slide on the inner wall of the slide groove 62 through the slider 64. This causes the spring 63 to be stretched by tension. When the half gear 61 continues to rotate, the half gear 61 no longer meshes with the rack 65, and the rack 65 loses its force. As a result, the slider 64 and the spring 63 lose their force. The spring 63 uses its own elasticity to drive the slider 64 and the rack 65 to reset, so that the scraper 66 fixed on the top of the slider 64 scrapes back and forth on the top of the mounting plate 2 to remove the dust, achieving a cleaning effect and enabling the heat dissipation device 5 to complete its work smoothly.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications 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. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
