Description

Technical Field

[0001] This utility model belongs to the technical field of deceleration mechanisms, specifically relating to a fully sealed, waterproof, and moisture-proof deceleration mechanism. Background Technology

[0002] A speed reducer is an independent component consisting of gear drives, worm drives, or gear-worm drives enclosed in a rigid housing. It is commonly used as a speed reduction transmission device between a prime mover and a working machine. It plays a role in matching speeds and transmitting torque between the prime mover and the working machine or actuator, and its applications are extremely widespread in modern machinery.

[0003] According to patent number CN202220179736.X, a speed reducer with a waterproof mechanism includes a speed reducer body. The speed reducer body includes a housing and a fixed cover. The fixed cover is fixedly installed at one end of the housing by a first screw. The fixed cover is configured as a cylindrical structure with one end open. A heat dissipation hole is opened on one side of the fixed cover. The heat dissipation hole is evenly distributed. A waterproof component is installed on the inner side of the fixed cover. The waterproof component is located on one side of the heat dissipation hole. The waterproof component includes a fixed plate and a waterproof and breathable membrane. The fixed plate is installed on the inner wall of the fixed cover. The waterproof and breathable membrane is installed on one side of the fixed plate by a second screw.

[0004] The above solution has certain technical defects in actual use. Although it can be waterproofed by using a waterproof and breathable membrane, it affects the air circulation. When the air contains a lot of moisture, some water will still enter the shell and affect its interior. In addition, in environments with large temperature differences between the inside and outside of the shell, water stains may condense on the waterproof and breathable membrane, which may not only cause the shell to rust, but may also cause the reducer to short circuit. Therefore, we propose a fully sealed waterproof and moisture-proof reduction mechanism. Utility Model Content

[0005] The purpose of this invention is to provide a fully sealed, waterproof, and moisture-proof deceleration mechanism to solve the existing problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fully sealed, waterproof, and moisture-proof speed reduction mechanism, comprising a speed reducer body, a heat sink cover, and a cooling plate. A heat dissipation cavity is provided at the end of the speed reducer body. The heat sink cover is fixedly installed on the outer periphery of the heat dissipation cavity by mounting screws. The heat sink cover is sealed to the outer periphery of the speed reducer body housing with waterproof sealant. A cylindrical heat-conducting plate is provided inside the heat sink cover. One end of the heat-conducting plate extends into the interior of the heat dissipation cavity, and the other end extends into the interior of the heat sink cover. The heat-conducting plate and the heat dissipation cavity are also fixedly connected by waterproof sealant. A cooling plate is provided on the surface of the end of the heat-conducting plate extending into the heat sink cover. The heat-absorbing end of the cooling plate is fixedly connected to the heat-conducting plate by thermally conductive silicone grease, and the heat-releasing end of the cooling plate is fixedly connected to heat dissipation fins by thermally conductive silicone grease.

[0007] Preferably, the heat sink has an air inlet at its end, a cooling fan is fixedly installed inside the air inlet, the cooling fan is fixedly installed inside the air inlet by mounting screws, and air outlets are symmetrically opened on both sides of the exterior of the heat sink.

[0008] Preferably, a heat-conducting rod is provided on the outer periphery of the cooling chip, the heat-conducting rod is arranged around the cooling chip, and the two sides of the heat-conducting rod are in close contact with the heat-conducting plate and the heat dissipation fins, respectively.

[0009] Preferably, a heat insulation layer is filled between the heat-conducting plate and the heat dissipation fins. The heat insulation layer wraps around the outer periphery of the cooling plate and the heat-conducting rod but does not affect their contact with the heat-conducting plate and the heat dissipation fins.

[0010] Preferably, a first dustproof net is provided on the outside of the air inlet, and one side of the outer periphery of the first dustproof net is fixedly installed on the outer periphery of the air inlet by adhesive bonding.

[0011] Preferably, a second dustproof net is provided on the inner side of the air outlet, and one outer periphery of the second dustproof net is fixedly installed on the inner side of the air outlet by adhesive bonding.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By using waterproof sealant to install the heat sink cover, the sealing between the heat sink cover and the reducer body housing is improved. Combined with the heat conduction plate and waterproof sealant to seal the heat dissipation cavity, a complete seal is achieved, effectively preventing the influence of external temperature and humidity environment on the inside of the reducer body housing. At the same time, the heat conduction plate, cooling plate and heat dissipation fins are used to diffuse heat into the heat sink cover by heat transfer. Finally, the heat dissipation fan, together with the air outlet, ventilates and dissipates heat inside the heat sink cover, ensuring stable heat dissipation effect.

[0014] 2. By setting heat-conducting rods on the outer periphery of the cooling chip, the contact area between the two sides of the cooling chip and the heat-conducting plate and heat dissipation fins is increased, thereby improving the efficiency of heat transfer and indirectly improving the heat dissipation effect. In conjunction with the heat insulation layer, the heat absorption end and heat release end of the cooling chip are isolated to avoid the internal temperature of the heat dissipation cover affecting the cooling chip and reducing the operating efficiency of the cooling chip.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 This utility model provides a fully sealed, waterproof, and moisture-proof speed reduction mechanism: it includes a speed reducer body 1, a heat sink 2, and a cooling plate 6. A heat dissipation cavity 3 is provided at the end of the speed reducer body 1. The heat sink 2 is fixedly installed on the outer periphery of the heat dissipation cavity 3 by mounting screws. The heat sink 2 and the outer periphery of the housing of the speed reducer body 1 are sealed with a waterproof sealant 14. A columnar heat-conducting plate 5 is provided inside the heat sink 2. One end of the heat-conducting plate 5 extends into the interior of the heat dissipation cavity 3, and the other end of the heat-conducting plate 5 extends into the interior of the heat sink 2. The heat-conducting plate 5 and the heat dissipation cavity 3 are also fixedly connected by a waterproof sealant 14. A cooling plate 6 is provided on the surface of the end of the heat-conducting plate 5 that extends into the interior of the heat sink 2. The heat-absorbing end of the cooling plate 6 is fixedly connected to the heat-conducting plate 5 by thermally conductive silicone grease, and the heat-releasing end of the cooling plate 6 is fixedly connected to heat dissipation fins 9 by thermally conductive silicone grease.

[0021] Specifically, the heat sink 2 has an air inlet 10 at its end, and a cooling fan 11 is fixedly installed inside the air inlet 10. The cooling fan 11 is fixedly installed inside the air inlet 10 by mounting screws. Air outlets 4 are symmetrically opened on both sides of the exterior of the heat sink 2.

[0022] Specifically, a heat-conducting rod 7 is provided on the outer periphery of the cooling chip 6. The heat-conducting rod 7 is arranged around the cooling chip 6, and the two sides of the heat-conducting rod 7 are in close contact with the heat-conducting plate 5 and the heat dissipation fins 9, respectively.

[0023] Specifically, a heat insulation layer 8 is filled between the heat-conducting plate 5 and the heat dissipation fins 9. The heat insulation layer 8 wraps around the outer periphery of the cooling chip 6 and the heat-conducting rod 7 but does not affect their contact with the heat-conducting plate 5 and the heat dissipation fins 9.

[0024] Specifically, a first dustproof net 12 is provided on the outside of the air inlet 10, and one side of the outer periphery of the first dustproof net 12 is fixedly installed on the outer periphery of the air inlet 10 by adhesive bonding.

[0025] Specifically, a second dustproof net 13 is provided on the inner side of the air outlet 4, and one side of the outer periphery of the second dustproof net 13 is fixedly installed on the inner side of the air outlet 4 by adhesive bonding.

[0026] In this embodiment, during use, the heat inside the heat dissipation cavity 3 is absorbed by the heat-conducting plate 5 and then transferred to the interior of the heat dissipation cover 2 from the other end of the heat-conducting plate 5. The cooling fin 6, which is set at one end of the heat-conducting plate 5, absorbs the heat dissipated by the heat-conducting plate 5 at its heat-absorbing end and then transfers it to the heat dissipation fins 9 from its heat-releasing end. At the same time, the heat-conducting rod 7 is used to increase the contact area between the cooling fin 6 and the heat-conducting plate 5 and the heat dissipation fins 9, thereby improving the efficiency of heat transfer and indirectly improving the heat dissipation efficiency. After absorbing heat, the heat dissipation fins 9 diffuse it into the interior of the heat dissipation cover 2. Finally, the cooling fan 11 draws in outside air, filters it through the first dustproof net 12, and injects it into the interior of the heat dissipation cover 2 to ventilate and dissipate heat on the surface of the heat dissipation fins 9. The heat diffused by the heat dissipation fins 9 is discharged through the air outlet 4, thereby achieving the purpose of heat dissipation. This design makes the heat dissipation cavity 3 completely closed, and the external temperature and humidity environment is unlikely to affect the interior of the reducer body 1, while effectively ensuring the stability of the heat dissipation efficiency.
