[0031] Example 1

[0032] Reference Figures 1-4 This invention provides a quick-assembly, anti-loosening automotive electronic fan. Due to the tight fit between the rocker arm 203 and the slot 202, the fan is effectively prevented from loosening during vehicle operation due to bumps or other reasons, thus improving the fan's stability and reliability. It includes a main body unit 100 and a mounting unit 200.

[0033] The housing 101 in the main unit 100 serves as the supporting structure for the entire fan, protecting the internal fan components and ensuring their proper operation. The symmetrically arranged skirts 102 on the housing 101 not only increase structural stability but also provide crucial connection points for subsequent installation. The symmetrically formed mounting holes 103 on the skirts 102 are essential for engaging with the mounting pins 201 in the mounting unit 200. By aligning the mounting holes 103 with the mounting pins 201, the initial positioning of the fan can be quickly achieved, significantly improving installation efficiency and saving time compared to traditional installation methods in finding the installation location.

[0034] The fixing pin 201 in the mounting unit 200 is fixedly mounted on the car radiator, and its position precisely corresponds to the fixing hole 103, ensuring that the fan can be accurately installed on the radiator. The slot 202 on the fixing pin 201 is the key part to prevent the fan from loosening. The pry bar 203 symmetrically arranged on the skirt plate 102 has one end extending into the slot 202. When the pry bar 203 moves, it can tightly cooperate with the slot 202, thereby firmly fixing the fan to the radiator. The pry block 204 at the bottom of the pry bar 203 abuts against the top of the skirt plate 102, and the bottom end of the pry block 204 is designed to be hemispherical. The top of the skirt plate 102 has a T-shaped sliding groove 205, and a T-shaped slider 206 is slidably connected in the T-shaped sliding groove 205. The T-shaped slider 206 is rotatably connected to the pry block 204. This unique design allows the pry bar 204 to slide within the T-shaped groove 205 and rotate around the T-shaped slider 206 when the rocker arm 203 moves, flexibly adapting to various movement states of the rocker arm 203 and ensuring the stability and reliability of the cooperation between the rocker arm 203 and the slot 202.

[0035] During use, firstly, align the fixing holes 103 of the skirt plate 102 of the main unit 100 with the fixing pins 201 on the car radiator for initial positioning. Then, by applying external force, the pry bar 203 moves, and the pry block 204 at the bottom of the pry bar 203 slides and rotates within the T-shaped groove 205, gradually pushing one end of the pry bar 203 deeper into the slot 202. As the pry bar 203 moves further, it engages tightly with the slot 202, firmly fixing the fan to the radiator. This installation method is simple and quick, significantly shortening installation time and improving efficiency compared to traditional bolt and nut installation methods. Simultaneously, the tight engagement between the pry bar 203 and the slot 202 effectively prevents the fan from loosening due to bumps or other factors during vehicle operation, improving the fan's stability and reliability.

[0036] Example 2

[0037] Reference Figures 1 to 3 This is the second embodiment of the present invention. Unlike the previous embodiment, the drive assembly consists of a lifting member and a locking member disposed on the skirt plate 102. The locking member is disposed on the top of the lifting member and is used to lock the position of the lifting member to ensure that the fan will not loosen due to external factors after it is fixed.

[0038] The lifting component includes a screw 207 and a screw block 208. The screw block 208 is fitted onto the screw 207 and is threadedly connected to the screw 207. A connecting shaft 209 is symmetrically arranged on the screw block 208. The connecting shaft 209 engages with the end of the rocker arm 203 furthest from the annular groove 202 via a hinge hole. When the screw 207 is rotated, according to the threaded transmission principle, the screw block 208 moves up and down along the screw 207. Since the connecting shaft 209 engages with the rocker arm 203 via the hinge hole, the up-and-down movement of the screw block 208 causes the rocker arm 203 to rotate around its connection point with the skirt plate 102, thereby enabling the rocker arm 203 to be pressed or released within the groove 202, completing the installation and removal of the fan.

[0039] To ensure the stability and accuracy of the movement of the screw block 208, symmetrical limit grooves 210 are formed on the screw block 208, and symmetrical limit rods 211 that slide in cooperation with the limit grooves 210 are fixedly connected to the skirt plate 102. The limit rods 211 extend vertically and pass through the limit grooves 210. The function of the limit rods 211 is to restrict the movement trajectory of the screw block 208, so that it can only move in the vertical direction, thereby preventing the screw block 208 from deviating or shaking during movement and ensuring that the drive assembly can work stably and reliably.

[0040] The locking assembly includes a connecting plate 212 fixedly mounted on the top of the two limit rods 211. A boss 213 is fixedly connected to the connecting plate 212, and a worm gear 214 is rotatably connected to the boss 213. A through hole 219 is provided on the connecting plate 212. The top end of a screw 207 passes through the through hole 219 and is rotatably connected to the through hole 219. A worm wheel 215 is fixedly connected to the top end of the screw 207, and the worm gear 214 is meshed with the worm wheel 215. An extension shaft 216 is fixedly connected to one end of the worm gear 214. The extension shaft 216 passes through the boss 213 and is fixedly connected to a standard hexagonal head 217, which is adapted to a wrench. By using a wrench to rotate the standard hexagonal head 217, the worm gear 214 is driven to rotate. Since the worm gear 214 is meshed with the worm wheel 215, the rotation of the worm gear 214 will drive the worm wheel 215 to rotate, thereby causing the screw 207 to rotate. Once the screw 207 is rotated to the appropriate position and the fan is fixed in place, the self-locking characteristics of the worm gear 215 and worm 214, along with the function of the locking component, can effectively lock the position of the lifting component and prevent the fan from becoming loose.

[0041] During use, first use a wrench to turn the standard hex head 217, which drives the worm gear 214 to rotate. The worm gear 214 drives the worm wheel 215 to rotate, thereby rotating the screw 207. Under the rotation of the screw 207, the screw block 208 moves upward along the vertical direction defined by the limiting rod 211. The connecting shaft 209 on the screw block 208 drives one end of the rocker arm 203 to move upward, while the other end of the rocker arm 203 rotates around its connection point with the skirt plate 102. This causes the end of the rocker arm 203 located in the slot 202 to press downward against the slot 202, firmly fixing the fan to the water tank. When it is necessary to disassemble the fan, turn the standard hex head 217 in the opposite direction. The screw 207 reverses direction, and the screw block 208 moves downward along the limiting rod 211, causing one end of the rocker arm 203 to move downward. This causes the end of the rocker arm 203 located in the slot 202 to lift upward, releasing the pressure on the slot 202, allowing the fan to be removed from the water tank. This drive component design makes fan installation and removal more convenient and efficient, while also improving the fan's secureness and stability.

[0042] Example 3

[0043] Reference Figures 1 to 3 This is the third embodiment of the present invention. Unlike the previous embodiment, a silicone pad 218 is fixedly connected to the bottom of the skirt panel 102. The silicone pad 218 is double-layered, with an upper layer of silicone with a Shore hardness of 80±5 and a lower layer of silicone with a Shore hardness of 40±5. The two layers are integrally formed through a molding and vulcanization process. The upper silicone layer, with its higher hardness, provides better support and wear resistance, capable of withstanding the pressure and vibration generated by the fan during operation, protecting the lower silicone layer and the skirt panel 102 from damage. The lower silicone layer, with its lower hardness, has good flexibility and conformability, allowing it to better fit the surface of the car's radiator, filling the gap between the skirt panel 102 and the radiator, thus providing a good seal. Simultaneously, the silicone pad 218 also has a buffering effect, reducing the transmission of vibration and noise generated during fan operation to the radiator, thus reducing the impact of noise on the driver and passengers.

[0044] During use, when the fan is installed on the radiator, the silicone gasket 218 at the bottom of the skirt 102 makes tight contact with the radiator surface. The lower silicone layer adapts to the shape of the radiator surface, filling gaps and preventing dust and moisture from entering the connection between the fan and the radiator, thus avoiding corrosion and loosening of components due to dust and moisture accumulation. The upper silicone layer provides support for the lower silicone layer, ensuring that the silicone gasket 218 will not deform or be damaged during long-term use. In addition, the cushioning effect of the silicone gasket 218 can reduce vibration during fan operation, extend the service life of the fan and radiator, and improve the stability and reliability of the entire automotive cooling system.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
