DETAILED DESCRIPTION

[0023] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figure 1-6 As shown, the present embodiment provides a small servo motor for adjusting the saddle of an electric bicycle, which includes a shell 1, a detachable servo motor 2 installed inside the shell 1, a heat sink 3 fixedly installed on the top of the shell 1, and a heat dissipation structure 25 provided between the shell 1 and the heat sink 3; the heat dissipation structure 25 includes two heat conducting plates 4 symmetrically installed inside the shell 1, a plurality of heat conducting pipes 5 fixedly installed between the two heat conducting plates 4, and fins 6 fixedly installed on the heat conducting pipes 5; a support frame 7 is fixedly installed inside the heat dissipation box 3, and a plurality of heat dissipation fans 8 are fixedly installed on the support frame 7, and the heat dissipation fan 8 is located on one side of the fin 6; a plurality of air outlets 9 are provided on both sides of the heat dissipation box 3, and one side of the heat conducting plate 4 is in contact with one side of the servo motor 2.

[0025] In this embodiment, the heat generated by the operation of the servo motor 2 can be quickly conducted to the heat pipe 5 through the heat conduction plate 4, and the heat on the heat conduction plate 4 is quickly conducted to the fins 6 through the heat conduction pipe 5 and quickly dissipated, thereby achieving rapid heat dissipation and cooling of the servo motor 2; at the same time, the cooling fan 8 is started to generate air flow to continuously blow air in the direction of the fins 6 to ensure that the heat on the fins 6 is evenly blown away and dissipated through the air outlet 9, thereby accelerating the transfer and dissipation of heat and further improving the heat dissipation effect.

[0026] like Figure 1 and Figure 4 As shown, a plurality of slide bars 10 are fixedly mounted inside the housing 1 , a plurality of fixing blocks 11 are fixedly mounted on the servo motor 2 , the fixing blocks 11 are slidably connected to the slide bars 10 , and the housing 1 and the servo motor 2 are fixed by bolts 22 .

[0027] In this embodiment, when the servo motor 2 needs to be inspected and maintained, the bolt 22 is rotated and removed so that it no longer limits and fixes the servo motor 2, making it easy to take out the servo motor 2 for inspection and maintenance; after the inspection and maintenance is completed, the servo motor 2 can be quickly slid into the interior of the housing 1 by aligning the slide bar 10 with the fixing block 11. The slide bar 10 can reduce the friction when the servo motor 2 moves, and also prevent lateral deviation of the servo motor 2 during movement, which helps the servo motor 2 to remain stable when moving. The servo motor 2 is again limited and fixed by the bolt 22 to prevent shaking, completing the quick installation.

[0028] like Figure 4 As shown, a ventilation cover 12 is fixedly mounted on one side of the housing 1 , a support frame 13 is fixedly mounted inside the ventilation cover 12 , an exhaust fan 14 is fixedly mounted on one side of the support frame 13 , and a filter screen 15 is mounted on one side of the ventilation cover 12 .

[0029] In this embodiment, starting the exhaust fan 14 to generate airflow can continuously transport external air to the interior of the shell 1 for circulation and ventilation, thereby blowing air to cool the heat conduction plate 4 and the servo motor 2, further improving the cooling and heat dissipation effect; the setting of the filter 15 can filter dust particles in the air, preventing dust from entering the interior of the servo motor 2 and affecting the normal operation of the servo motor 2.

[0030] like Figure 4-Figure 6 As shown, a plurality of mounting blocks 16 are fixedly installed on one side of the ventilation hood 12, and a plurality of mounting grooves 17 compatible with the mounting blocks 16 are opened on one side of the filter screen 15. Two slots 18 are symmetrically opened on the mounting block 16, and a telescopic rod 19 is fixedly installed inside the slot 18. A card ball 20 is fixedly installed at one end of the telescopic rod 19. A card slot compatible with the card ball 20 is opened on the inner wall of the mounting groove 17, and a spring 21 is provided on the surface of the telescopic rod 19. The two ends of the spring 21 are respectively connected to the surface of the card ball 20 and the inner wall of the slot 18. The diameter of the top of the mounting block 16 is smaller than the diameter of the bottom.

[0031] In this embodiment, when the filter 15 needs to be cleaned or replaced after being used for a long time, the filter 15 is pulled outward. When the filter 15 moves outward, it squeezes the card ball 20. When the card ball 20 is squeezed, it squeezes the telescopic rod 19 and the spring 21 inward to continuously shrink until the card ball 20 is out of the card slot and no longer limits the filter 15. It is convenient to take out the filter 15 for cleaning or replacement, and prevent dust from clogging the filter 15 and affecting the air flow. When installing, align the mounting block 16 with the mounting slot 17 and insert it into the mounting slot. The mounting block 16 is pushed into the mounting slot. When the card ball 20 moves in the slot 18, it will squeeze the telescopic rod 19 and the spring 21 inward to shrink when it is squeezed. The card ball 20 shrinks to the inside of the slot 18 until the slot 18 fits with the card slot. The elasticity of the telescopic rod 19 and the spring 21 is used to drive the card ball 20 to rebound to the inside of the card slot, limiting and fixing the filter 15 to prevent the filter 15 from shaking and falling off, thereby completing quick disassembly and replacement; the diameter of the top of the mounting block 16 is smaller than the diameter of the bottom, so that when the mounting block 16 is inserted into the mounting slot 17, the insertion resistance is reduced, thereby improving installation efficiency.

[0032] like Figure 1 As shown, two bases 23 are symmetrically mounted on the bottom of the housing 1 , and a plurality of threaded holes 24 are formed on the bases 23 .

[0033] The above description shows and describes the preferred embodiments of the present invention. It should be understood that the present invention is not limited to the form disclosed herein. Any changes and modifications made by those skilled in the art without departing from the spirit and scope of the present invention should be within the scope of protection of the claims attached to the present invention.
