Description

Technical Field

[0001] This utility model relates to the field of automotive engine fan technology, and in particular to an automotive engine fan with strong shock resistance. Background Technology

[0002] The car engine fan is a key component installed in the engine cooling system. It generates airflow by rotating, drawing in cool air from the front of the radiator and blowing it to the back of the radiator, thereby improving cooling efficiency and preventing the engine from overheating. There are many types of car engine fans, including mechanical car engine fans and electronic car engine fans.

[0003] To address this, patent CN205592186U discloses an automotive engine cooling fan, including a support plate and fan blades distributed circumferentially along the support plate. The front of the fan blades is a suction surface, and the back of the fan blades is a pressure surface. When the automotive engine cooling fan rotates, it blows air from the suction surface to the pressure surface. The back of the fan blades is provided with pressure surface guide ribs that guide the airflow in the direction of the wind. This invention improves the fan's cooling effect by guiding the airflow through the pressure surface guide ribs, thus reducing the change in blade lift caused by centrifugal force and unstable airflow at higher fan speeds. Furthermore, it features low noise and minimal vibration.

[0004] Existing automotive engine fans are installed by using bolts to connect the fan to the air guard. These bolts are prone to loosening, resulting in poor stability of the connection between the engine fan and the air guard, which affects the performance. Utility Model Content

[0005] The purpose of this invention is to provide a car engine fan with strong shock resistance, in order to solve the defect of poor connection stability between the existing car engine fan and the windshield.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a car engine fan with strong shock resistance, comprising an engine fan component, the engine fan component being evenly mounted on a rotating shaft, a first connecting plate being mounted on the outer side of one end of the rotating shaft, the first connecting plate being provided with a lubrication structure, a wind guard ring being provided at one end of the engine fan component, a mounting plate being provided inside the wind guard ring, the mounting plate being connected and fixed to the wind guard ring by an arm beam, a second connecting plate being mounted at one end inside the mounting plate, a protective structure being provided between the second connecting plate and the mounting plate, the second connecting plate being connected to the first connecting plate by fixing bolts, a positioning structure being provided between the second connecting plate and the first connecting plate, the positioning structure including a positioning groove formed on the inner wall of one end of the second connecting plate and a positioning block installed at one end of the first connecting plate.

[0007] Preferably, the lubrication structure includes a lubrication tank, a lubrication channel, a sponge pad, and a sealing plug. The lubrication tank is mounted on the first connecting plate. A sponge pad is installed at the bottom of the inside of the lubrication tank. An oil filling port is installed at the top of the lubrication tank, and a sealing plug is installed on the oil filling port. The bottom of the lubrication tank is connected to the lubrication channel at the top of the inside of the first connecting plate.

[0008] The above structure allows for lubrication of the rotating shaft, preventing wear caused by excessive friction between the rotating shaft and the first connecting disc.

[0009] Preferably, the protective structure includes a damper, a limiting block, a limiting groove, a recess, a telescopic rod, and a telescopic spring. The recess is formed inside the mounting plate, and dampers are symmetrically installed inside the recess. Telescopic rods are evenly installed on both sides inside the recess, and each telescopic rod is fitted with a telescopic spring. Limiting grooves are evenly formed on the inner sidewall of the recess, and limiting blocks are evenly installed on the outer side of the second connecting plate.

[0010] The above structure enhances the vibration resistance of the engine fan components and improves their performance.

[0011] Preferably, the limiting block is inserted into the limiting groove and forms a sliding connection therewith.

[0012] Preferably, one end of the telescopic spring is connected to the other end of the second connecting disc, and the telescopic spring and the second connecting disc form a telescopic structure.

[0013] The above structure further enhances the vibration resistance of the engine fan components.

[0014] Preferably, the positioning block and the positioning groove cooperate to form an engagement structure.

[0015] The above structure allows for positioning when the first and second connecting discs are docked, enhancing the stability of the connection between the engine fan components and the air guard ring.

[0016] Preferably, the fixing bolts are arranged at equal intervals between the second connecting plate and the first connecting plate.

[0017] The above structure improves the stability of the connection between the second connecting plate and the first connecting plate.

[0018] The present invention provides a car engine fan with strong shock resistance, the advantages of which are:

[0019] The positioning structure can position the first connecting plate and the second connecting plate when they are docked, enhancing the stability of the connection between the engine fan component and the air guard ring. The protective structure can enhance the vibration resistance of the engine fan component and improve its performance. The lubrication structure can lubricate the shaft and prevent wear caused by excessive friction between the shaft and the first connecting plate.

[0020] With the positioning structure set, the positioning block is inserted into the positioning groove, which can be positioned when the first connecting plate and the second connecting plate are docked, to prevent the first connecting plate and the second connecting plate from sliding against each other, and to enhance the stability of the connection between the engine fan component and the air guard ring.

[0021] By using the protective structure, telescopic springs, telescopic rods and dampers in combination, a certain shock absorption effect can be achieved, protecting the engine fan components, enhancing their shock resistance and improving their performance.

[0022] Through the designed lubrication structure, under the influence of gravity, the lubricating oil in the lubrication tank passes through the sponge pad and is discharged through the lubrication channel, dripping onto the surface of the rotating shaft to achieve the purpose of lubrication and avoid wear caused by excessive friction between the rotating shaft and the first connecting plate.
