Description

Technical Field

[0001] This utility model belongs to the technical field of fan mounting components, and more specifically, it relates to a radiator fan mounting component. Background Technology

[0002] During vehicle operation, the engine, transmission, and various electronic devices continuously generate a large amount of heat. Taking the engine as an example, the combustion temperature in its combustion chamber can reach thousands of degrees Celsius. If this heat cannot be dissipated in time, the engine operating temperature will rise sharply, leading to a decrease in lubricating oil viscosity, increased wear of parts, and in severe cases, even engine knocking, cylinder scoring, and other malfunctions, which will greatly affect the vehicle's power performance, reliability, and service life. As a key component of the vehicle's cooling system, the radiator fan plays a crucial role. It accelerates airflow and promotes heat exchange between the radiator and the outside air. To maintain the stability of the radiator on the vehicle, an installation component is required.

[0003] Based on existing technology, it has been found that some existing radiator fan installation methods that use bolt connections are prone to bolt loosening under long-term vibration. Once the bolts loosen, the fan will wobble during operation, which will not only reduce the heat dissipation effect, but may also cause damage to the components due to collisions between the fan and surrounding parts. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model relates to a radiator fan mounting assembly, which solves the problem that some existing radiator fan mounting methods using bolt connections are prone to bolt loosening under long-term vibration. Once the bolts loosen, the fan will shake during operation, which not only reduces the heat dissipation effect but may also cause damage to components due to collisions between the fan and surrounding parts.

[0005] This utility model provides a radiator fan mounting assembly, achieved through the following specific technical means: A radiator fan mounting assembly includes: a mounting plate; four sets of locking bolt holes on the mounting plate; an inner fixing plate fixed to the outside of the mounting plate by screws; four sets of adjustment grooves on the edge of the inner fixing plate; anti-loosening bolts installed inside the four sets of adjustment grooves; an outer mounting plate on the outside of the inner fixing plate; four sets of mating bolt holes on the outer mounting plate; an auxiliary radiator plate fixed to the outside of the outer mounting plate; heat dissipation holes on the auxiliary radiator plate; a fan frame fixed to the outside of the auxiliary radiator plate; a protective outer plate on the outside of the fan frame; and four sets of fixing bolts rotatably connected to the protective outer plate.

[0006] Preferably, the mounting plate is located at the vehicle body mounting position; the outer side of the inner fixing plate is provided with equidistant meshing grooves.

[0007] Preferably, the adjusting groove and the corresponding locking bolt hole are aligned on the same axis.

[0008] Preferably, the four sets of anti-loosening bolts are configured as hexagonal prisms, and threaded rod-shaped protrusions are fixed to the two bottom surfaces of the four sets of anti-loosening bolts respectively. The threaded rods on one side of the four sets of anti-loosening bolts are respectively threaded into the corresponding locking bolt holes.

[0009] Preferably, the outer plate has a groove that engages with the inner plate's groove.

[0010] Preferably, the four sets of mating bolt holes are aligned with the corresponding adjusting grooves and locking bolt holes on the same axis; the interior of the four sets of mating bolt holes is connected to the threaded rod on the other side of the corresponding anti-loosening bolt.

[0011] Preferably, the fan frame has a fan assembly inside; the protective outer plate is fixed to the fan frame by four sets of fixing bolts.

[0012] The radiator fan mounting assembly proposed in this utility model has the following beneficial effects: 1. The anti-loosening bolt adopts a hexagonal prism structure with threaded rod-shaped protrusions at both ends. It is connected by a two-way thread through the locking bolt hole of the mounting plate and the matching bolt hole of the outer plate to form a stable triangular fastening structure. This design can effectively resist vertical and horizontal vibrations during vehicle operation, prevent the loosening problem caused by vibration in traditional single bolt connections, and greatly improve the stability of fan installation. 2. The equidistant meshing grooves on the outer side of the inner plate and the grooves on the outer plate cooperate with each other to form a mechanical interlocking structure after the anti-loosening bolts are tightened. This structure not only increases the friction of the contact surface, but also disperses the stress transmitted by vibration, further reducing the risk of bolt loosening and ensuring that the fan can operate stably for a long time under complex road conditions.
