Description

Technical Field

[0001] This utility model relates to the field of garden engine heat dissipation technology, specifically a high-efficiency heat dissipation structure for the cylinder block of a small garden engine. Background Technology

[0002] Cooling the engine of a garden machinery is crucial for ensuring its normal operation. Here's some information about garden engine cooling: The Importance of Cooling to Prevent Overheating Damage: Garden engines generate a significant amount of heat during operation. If not cooled promptly, excessively high engine temperatures can cause parts to expand and deform, disrupting clearances, accelerating wear, and potentially leading to serious malfunctions such as cylinder scoring or bearing seizure, shortening engine lifespan and maintaining stable performance. Overheating also reduces the viscosity of engine lubricating oil, decreasing lubrication and increasing friction losses, resulting in decreased engine power and increased fuel consumption. Furthermore, high temperatures can affect the combustion process, causing incomplete combustion, carbon buildup, and further impacting engine performance.

[0003] Regarding the above-mentioned technical solutions, the existing heat dissipation structure cannot be adjusted according to the height of the engine block, making it difficult to adjust according to the model of the engine block. This affects its heat dissipation effect, and it lacks good protection. In actual use, dust can easily enter the inside of the fan blades, thus affecting the heat dissipation effect.

[0004] To address these issues, this invention provides a high-efficiency heat dissipation structure for the cylinder block of a small garden engine. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency heat dissipation structure for a small garden engine cylinder block, comprising a base plate, a heat dissipation component fixedly mounted on the top of the base plate, a power component fixedly mounted on the top of the base plate, and a protective component on one side of the heat dissipation component; the heat dissipation component comprises a fixing frame and a bidirectional threaded rod, the fixing frame being fixedly mounted on the top of the base plate, the bidirectional threaded rod being connected to the inner side wall of the fixing frame via a bearing, a gear being fixedly connected to the side wall of the bidirectional threaded rod, a moving block being threadedly connected to the side wall of the bidirectional threaded rod, a connecting rod being hinged to the top of the moving block, a lifting plate being hinged to the top of the connecting rod, heat dissipation fins being fixedly mounted on the top of the lifting plate, and a fan being provided on one side of the heat dissipation fins.

[0009] Furthermore, the protective component also includes a slot, which is formed on the top of the slide plate, and a lever is slidably connected to one side of the L-shaped frame, the lever engaging with the slot.

[0010] The above technical solution can achieve a reinforcement effect.

[0011] Furthermore, the protective component also includes a limiting piece, which is fixedly connected to the side wall of the lever.

[0012] The above technical solution can achieve a good limiting effect.

[0013] Furthermore, the protective assembly also includes a pull ring, which is fixedly connected to the top of the lever, and a limit block is fixedly installed on one side of the slide plate.

[0014] The above technical solution utilizes a pull ring to facilitate the movement of the lever.

[0016] The above technical solution can provide power to facilitate height adjustment.

[0017] Furthermore, the heat dissipation assembly also includes a stabilizing block, which is fixedly installed at the bottom of the movable block and is slidably connected to the base plate.

[0018] By adopting the above technical solution, stability can be improved, making the movement of the moving block more stable.

[0031] Reference Figures 1 to 4 This application provides a high-efficiency heat dissipation structure for a small garden engine cylinder block, including a base plate 1. A heat dissipation component 2 is fixedly installed on the top of the base plate 1, and a power component 3 is fixedly installed on the top of the base plate 1. The power component 3 includes a motor 31 and a gear 2 32. The motor 31 is fixedly installed on the top of the base plate 1, and the gear 2 32 is fixedly connected to the output end of the motor 31. The gear 2 32 is meshed with a gear 1 23. A protective component 4 is provided on one side of the heat dissipation component 2. The heat dissipation component 2 includes a fixing bracket 21 and a bidirectional threaded rod 22. The fixing bracket 21 is fixedly installed on the base plate 1. At the top, a bidirectional threaded rod 22 is connected to the inner wall of the fixed frame 21 via a bearing. A gear 23 is fixedly connected to the side wall of the bidirectional threaded rod 22. A movable block 24 is threadedly connected to the side wall of the bidirectional threaded rod 22. A connecting rod 25 is hinged to the top of the movable block 24. A lifting plate 26 is hinged to the top of the connecting rod 25. A heat dissipation fin 27 is fixedly installed on the top of the lifting plate 26. A fan 28 is provided on one side of the heat dissipation fin 27. The heat dissipation assembly 2 also includes a stabilizing block 29. The stabilizing block 29 is fixedly installed at the bottom of the movable block 24. The stabilizing block 29 is slidably connected to the base plate 1.

[0032] In this embodiment, the motor 31 is first started, which drives the gear 2 32 to rotate, which in turn drives the gear 1 23 to rotate, which in turn drives the bidirectional threaded rod 22 to move. Then, the bidirectional threaded rod 22 drives the moving block 24 to slide on the top of the base plate 1 through the stabilizing block 29, which allows the moving block 24 to drive the connecting rod 25 to adjust the height of the heat dissipation fins 27 and the fan 28 through the lifting plate 26, so that the heat dissipation fins 27 and the fan 28 can better cool the engine.

[0033] Reference Figures 1 to 4In one aspect of this embodiment, the protective component 4 includes an L-shaped frame 41 and a sliding plate 42. The L-shaped frame 41 is fixedly installed at the bottom of the lifting plate 26, and the sliding plate 42 is slidably connected to one side of the L-shaped frame 41. A protective shell 43 is fixedly installed on one side of the sliding plate 42. The protective component 4 also includes a slot 44, which is opened at the top of the sliding plate 42.

The protective component 4 also includes a pull ring 47, which is fixedly connected to the top of the locking rod 45. A limiting block 48 is fixedly installed on one side of the sliding plate 42.

[0034] In this embodiment, the sliding plate 42 can be pushed to slide on one side of the L-shaped frame 41, so that the protective shell 43 can protect the fan 28. Then, the pull ring 47 can be pulled to slide the locking rod 45 on one side of the L-shaped frame 41, so that the locking rod 45 can be engaged with the locking slot 44 to fix the protective shell 43, so that the protective shell 43 can have a good protective effect.

[0035] Working principle: First, starting the motor 31 drives the gear 2 32 to rotate, which in turn drives the gear 1 23 to rotate. The gear 1 23 then drives the bidirectional threaded rod 22 to move. The bidirectional threaded rod 22 then drives the moving block 24 to slide on the top of the base plate 1 through the stabilizing block 29. This allows the moving block 24 to drive the connecting rod 25 to adjust the height of the heat dissipation fins 27 and the fan 28 through the lifting plate 26, thus improving the cooling effect of the heat dissipation fins 27 and the fan 28 on the engine.

[0036] Then, push the slide plate 42 to slide on one side of the L-shaped frame 41, so that the protective shell 43 can protect the fan 28. Then pull the pull ring 47 to slide the locking rod 45 on one side of the L-shaped frame 41, so that the locking rod 45 can be engaged with the locking slot 44 to fix the protective shell 43, so that the protective shell 43 can have a good protective effect.
