Description

Technical Field

[0001] The utility model relates to the technical field of automobile radiators, in particular to a fan assembly for automobile radiators. Background Art

[0002] The automobile radiator is an important component of the engine cooling system. It is mainly composed of three parts: the water inlet chamber, the water outlet chamber and the radiator core. During operation, the engine's high-temperature coolant is distributed into the radiator core through the water inlet chamber. When the coolant flows in the flat tubes of the core, it is dissipated and cooled by the external flowing air. After cooling, it is concentratedly transported from the water outlet chamber to the coolant return pipe, realizing the circulation and cooling of the coolant.

[0003] Car radiators offer excellent heat dissipation, but the fan inside them is exposed to the outside world. This makes it easy for insects to enter and collide with the fan when the radiator is not running. After collision, proteins and other organic substances in the insect secretions can adhere to the fan blades, potentially breeding microorganisms. Microbial metabolites can further corrode the plastic. Furthermore, these organic substances can attract impurities such as dust, affecting the fan's cooling efficiency. Mosquito secretions contain a variety of components, including acids, proteins, peptides, lipids, and carbohydrates. Acids can corrode some plastics. Car radiator fans are typically made of engineering plastics, such as polyamide 66 (PA66). PA66 plastic offers excellent heat resistance and durability, but long-term exposure to acidic environments can damage its molecular structure, affecting the durability of the fan assembly. Consequently, current car radiator fan assemblies lack the necessary protective structures.

[0004] Based on this, a fan assembly for an automobile radiator is proposed. Utility Model Content

[0008] The rotating mechanism includes a gear ring, which is rotatably connected to one side of the fixed hoop. One end of the deflection shaft is connected to gear 2, which is meshed with the inner ring of the gear ring. The outer ring of the gear ring is connected to a transmission member for driving the gear ring to rotate.

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1:

[0026] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0027] A fan assembly for an automobile radiator includes a shell 1, which is fixedly connected to the inside of the automobile radiator. A connecting frame 2 is connected to one side of the shell 1, and a main motor 4 is connected to the connecting frame 2. The output end of the main motor 4 is connected to a rotating shaft 12, and the rotating shaft 12 is connected to fan blades 15. When the main motor 4 rotates, it can synchronously drive the fan blades 15 to rotate, so that the fan inside the radiator starts to run, achieving the effect of heat dissipation. A deflection shaft 10 is rotatably connected to the shell 1, and the deflection shaft 10 is connected to the shell 1, and four deflection shafts 10 are provided. A protective cover 11 is connected to one end of the rotating shaft 12. The protective cover 11 structure is set to four, and the number of protective covers 11 is the same as the number of deflection shafts 10. A rotating mechanism for driving the protective cover 11 to rotate is connected to one side of the shell 1.

[0028] Specifically, such as Figure 1 As shown, a fixing hoop 3 is connected to the connecting frame 2, and the main motor 4 is fixedly connected to the fixing hoop 3. By providing the fixing hoop 3, the firmness of the structural connection of the main motor 4 is improved, wherein the fixing hoop 3 is structurally sleeved on the main motor 4.

[0029] Specifically, such as Figure 2As shown, a limiting ring 13 is connected to the rotating shaft 12. By setting the limiting ring 13, when each protective cover 11 is combined, the area of ​​the fan assembly exposed to the external environment can be effectively reduced, and the internal structure has good sealing performance. When the protective cover 11 is docked, the limiting ring 13 can block the docking center of the protective cover 11. At this time, the limiting ring 13 is attached to one side of the docking center of the protective cover 11.

[0030] Specifically, such as Figure 3 As shown, the rotating mechanism includes a gear ring 6, which is rotatably connected to one side of the fixing hoop 3. One end of the deflection shaft 10 is connected to a gear 2 9, which is engaged with the inner ring of the gear ring 6. The outer ring of the gear ring 6 is connected to a transmission member for driving the gear ring 6 to rotate. Tooth structures are provided on both the inner and outer sides of the gear ring 6, wherein the outer tooth structure of the gear ring 6 is engaged with the gear 1 8, and the inner tooth structure of the gear ring 6 is engaged with multiple gear 2 9.

[0031] Specifically, such as Figure 5 As shown, a sleeve 14 is connected to one side of the fixed hoop 3, and a rotating frame 7 is connected to one side of the gear ring 6. The rotating frame 7 is rotatably connected to the sleeve 14. By setting the sleeve 14 to limit the structure of the rotating frame 7, the stability of the rotation of the gear ring 6 is improved, thereby avoiding contact between the rotating frame 7 and the output end of the main motor 4.

[0032] Specifically, such as Figure 3 As shown, the transmission part includes a side motor 5, which can rotate forward and reverse, and the forward and reverse angles can be precisely controlled, and correspond to the opening and closing of the protective cover 11 respectively. The side motor 5 is a direct reference to the existing technology. The more common motors with this function are stepper motors, DC motors and AC motors. The output end of the side motor 5 is connected to a gear 8, and the gear 8 is engaged with the outer ring of the gear ring 6. After the side motor 5 is started, it can drive the gear ring 6 to rotate a certain angle, thereby opening or closing the protective cover 11. After the rotation is completed, the side motor 5 stops running.

[0033] Example 2:

[0034] See also Figure 6 , which is different from the first embodiment, is that the number of deflection axes 10 is two. This type of deflection axis 10 can still protect the fan blade 15. In order to avoid motion interference, the number of deflection axes 10 is greater than or equal to two and less than or equal to six. The maximum rotation angle of the deflection axis 10 is 90°. The number of deflection axes 10 needs to be comprehensively considered, among which the optimal number of deflection axes 10 is four.

[0035] In summary, the fan assembly for a car radiator provided in this embodiment can shut down the main motor 4 when the fan assembly inside the car radiator is not in use, stop the rotation of the fan blades 15, start the side motor 5, and use the rotation of gear 1 8 to drive the gear ring 6 to rotate. At this time, the tooth structure on the inner side of the gear ring 6 will drive gear 2 9 to rotate, and each deflection shaft 10 starts to rotate, thereby driving the protective cover 11 to close to each other, completing the protection of the structure on one side of the fan assembly layer, thereby preventing the internal structure of the fan assembly from being corroded and improving the durability of the internal structure of the fan assembly.

[0036] The above description of the embodiments is intended to enable those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
