Description

Technical Field

[0001] The utility model relates to the field of stage lights, in particular to a heat dissipation base inside a stage light. Background Art

[0002] A Chinese utility model patent with the patent publication number CN221375602U discloses a stage light base. By fixedly arranging electrical components and the like inside the top cover, it effectively provides better protection for the internal electrical components, and there is a spaced space formed between the circuit board, the heat dissipation fan and the bottom cover, which can effectively protect the internal electrical components even when the base collides or drops. At the same time, a safety rope matching component is arranged on the bottom cover, which facilitates the installation of the safety rope and effectively stores the hanging ring when not in use. At the same time, a quick replacement structure for the battery and the moisture-proof beads is also arranged inside the base, which is convenient for regular replacement. Although this patent dissipates heat from the stage light base by means of an internal fan, it can improve the waterproof performance of the base and enhance safety by installing the electrical components upside down, but the position of the internal heat dissipation fan is not well arranged. When the heat dissipation fan blows air in a closed space during operation, due to the unreasonable air duct design and the relatively random air direction, the heat dissipation efficiency will be affected.

[0032] For the embodiments, please refer to Figures 1-3 as shown in

[0033] A heat dissipation base inside a stage light, comprising a base 100; a base cover 110 is connected above the base 100; an accommodation space is formed inside the base cover 110; the base cover 110 is approximately a bottomless cuboid thin shell structure as a whole, and an accommodation space approximately in the shape of a cuboid is formed inside after the base cover 110 is fixedly connected to the base 100; a top plate 111 is formed at the top of the base cover 110; an installation plate 120 located inside the accommodation space is fixedly connected inside the top plate 111; electrical components 130 and a first circuit board 140 are connected to the installation plate 120; multiple installation plates 120 can be provided; as Figure 1 shown, two installation plates 120 are arranged in parallel. Electrical components 130 are installed at the bottom of the upper installation plate 120, and the first circuit board 140 and a heat dissipation fan 160 are installed at the bottom of the lower installation plate 120;

[0034] The first circuit board 140 and the installation plate 120 are arranged at intervals, so that the wind blown out by the heat dissipation fan 160 can pass through the upper and lower end faces of the first circuit board 140, increasing the contact area with the first circuit board 140 and being able to take away heat faster; the heat dissipation fan 160 is arranged on one side of the first circuit board 140; the air outlet direction of the heat dissipation fan 160 passes through the first circuit board 140 and faces the length direction of the top plate 111; the bottom of the heat dissipation fan 160 is arranged at an interval from the base 100; the air outlet direction of the heat dissipation fan 160 is along the length direction of the top plate 111, which can reduce the blockage of the wind by internal components, enable the air blown out by the heat dissipation fan 160 to travel a longer distance, and when blowing along the length direction, the fluidity of the wind is relatively better. The first circuit board 140 directly faces the air outlet of the heat dissipation fan 160, and the first circuit board 140 is arranged parallel to the top plate 111, with a small wind blocking area, which is conducive to air outlet;

[0035] Furthermore, the heat dissipation fan 160 is installed on the installation plate 120 and the bottom of the heat dissipation fan 160 is arranged at an interval from the base 100, and the wind blown out by the heat dissipation fan 160 is more likely to form a circulating wind in the accommodation space in the direction shown by the thick black line in Figure 6 This makes the internal air blowing have better fluidity, can ensure a relatively fast flow speed, which is conducive to heat transfer, and the heat can be better transferred to the outside through the base cover 110 and the base 100;

[0036] In one embodiment, a second circuit board 150 is connected below the first circuit board 140 through connecting posts 141. Four connecting posts 141 are provided, which are respectively located at the four corners of the first circuit board 140. Such a design can realize the arrangement of a double-layer circuit board, and the structure of the double-layer circuit board cooperates with the cooling fan 160 to have a better heat dissipation effect. It should be noted that the bottom of the second circuit board 150 is also spaced from the base 100, so that both the upper and lower end faces of the second circuit board 150 can be used for heat dissipation. The first circuit board 140 and the mounting plate 120 can be spaced apart by using shorter connecting posts 141 or by using sleeves. For example, sleeves are provided at the bottom of the mounting plate 120. The sleeves have internal threads, and the first circuit board 140 is fixed to the internal threads of the sleeves by screws, and the length of the sleeves spaces the first circuit board 140 from the mounting plate 120.

[0037] In one embodiment, the electrical component 130 is arranged on the side of the first circuit board 140 and parallel to the air outlet direction of the cooling fan 160, so as not to block the air outlet of the cooling fan 160. The electrical component 130 mainly uses the circulating air formed by the cooling fan 160 for heat dissipation, and does not require the cooling fan 160 to blow directly.

[0038] In one embodiment, a support frame 170 is fixedly connected between the top plate 111 and the base 100. The support frame 170 is located in the accommodation space. Two support frames 170 are arranged opposite to each other. The support frame 170 can be used to enhance the strength of the base cover 110 to prevent it from deforming due to dropping and can also enhance its bearing capacity. Heat dissipation fins 112 are arranged at intervals on the outer side of the base cover 110. By providing the heat dissipation fins 112, the heat dissipation effect of the base cover 110 can be effectively improved.

[0039] In one embodiment, a lifting plate assembly 180 and several support feet 113 are installed at the bottom of the base 100. Usually, four support feet 113 are provided, which are respectively located at the four corners of the base 100.

By providing the handle 210, it is convenient to take and carry the base 100.

[0041] In one embodiment, the handle 210 includes a connecting portion 211 movably connected to the arm portion 200; as Figure 2 shown, in this embodiment, the handle 210 is U-shaped, and the connecting portions 211 are the two ends of the handle 210; the connecting portion 211 includes a rotating portion 212 and a limiting groove 213; the arm portion 200 is provided with a receiving cavity 220 capable of receiving the connecting portion 211; a guiding sliding groove 221 cooperating with the rotating portion 212 and a limiting post 222 capable of cooperating with the limiting groove 213 are provided in the receiving cavity 220; the limiting post 222 is arranged at the bottom of the receiving cavity 220; during operation, the rotating portion 212 can rotate relative to the guiding sliding groove 221 or slide along the guiding sliding groove 221; the axial direction of the limiting post 222 is parallel to the extending direction of the guiding sliding groove 221, which can ensure that the limiting post 222 smoothly cooperates with the limiting groove 213 during guiding;

[0042] As Figure 2 , Figure 3 , Figure 5 shown, the handle 210 is in a retracted state in the figure, and the rotating portion 212 of the handle 210 cooperates with the Figure 3 end portion on the right side of the guiding sliding groove 221 in the figure. When in use, pick up the handle 210 and rotate it counterclockwise by 90°. At this time, the connecting portion 211 of the handle 210 will move relative to the receiving cavity 220, push the handle 210 towards the middle of the base cover 110, and the rotating portion 212 will slide along the direction of the guiding sliding groove 221, so that the limiting post 222 is inserted into the limiting groove 213, and the position of the handle 210 is fixed. At this time, the handle 210 cannot rotate relative to the rotating portion 212, and the base 100 can be carried more conveniently; in one embodiment, the extending direction of the guiding sliding groove 221 is the horizontal direction, so that the handle 210 can be in a horizontal state after being fixed; in one embodiment, the position of the handle 210 can also be not fixed for use, and the handle 210 can be directly rotated to pick up the base 100;

[0043] In one embodiment, a limiting baffle 223 is provided at one end of the guiding sliding groove 221 away from the bottom of the receiving cavity 220. By providing the limiting baffle 223, the limiting baffle 223 is used as a detachable structure, which can facilitate the installation and disassembly of the handle 210;

[0044] In one embodiment, the arm portion 200 includes a fixing portion 230 fixedly connected to the base cover 110; an outer cover portion 240 is connected to the outside of the fixing portion 230; a receiving groove 241 for receiving the handle 210 is provided on the outer cover portion 240; the receiving cavity 220 is arranged on the fixing portion 230.
