Description

Technical Field

[0001] The present invention relates to the technical field of automobile wheels, and in particular to a low wind resistance wheel. Background Art

[0002] Major OEMs are now developing large aluminum wheel covers. These covers can meet diverse customer aesthetic requirements, while also reducing wind resistance. However, due to high brake temperatures during continuous braking, fully enclosed wheel covers prevent effective heat dissipation, leading to reduced braking force.

[0003] For example, announcement number CN110588238A, published on December 20, 2019, discloses a wheel comprising a rim and spokes. The spokes are disposed at one axial end of the rim and have ventilation holes formed therein. At least a portion of the edges of the ventilation holes are bent toward the axial inner side of the rim to form a bent flange. At least a portion of the bent flange is abutted against the inner wall of the rim and welded to the rim to form a first weld bead at the junction of the two. The ventilation holes in the wheel disclosed above can cool the wheel and brakes, but the wheel has high wind resistance and poor practicality. Summary of the Invention

[0004] The present invention aims to provide a low-drag wheel with enhanced practicality. This invention reduces wheel wind resistance by sealing the ventilation holes with a shielding plate. When cooling is required, the power supply assembly causes the drive assembly to rotate the shielding plate, causing the ventilation holes on the shielding plate to coincide with the ventilation holes on the wheel, thereby cooling the brakes. This, in turn, reduces wheel wind resistance and brake cooling, resulting in enhanced practicality.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention to solve its technical problems is: a low wind resistance wheel, including a wheel and a brake arranged on the wheel, the wheel is provided with ventilation holes, the wheel is provided with a shielding plate, the shielding plate is provided with air holes, the wheel is provided with a driving component for driving the shielding plate to move, and the wheel is provided with a power supply component for supplying power to the driving component.

[0006] The driving assembly includes a solenoid valve arranged on the wheel, and a piston of the solenoid valve is connected to the shielding disk.

[0007] A hook is provided on the piston of the electromagnetic valve, and a clamping seat matched with the hook is provided on the shielding disk.

[0008] The shielding disk is annular, and a fixed wheel is provided in the air vent of the shielding disk. The fixed wheel is connected to the wheel, and a groove is provided on the fixed wheel for engaging with the shielding disk. The shielding disk can rotate around the fixed wheel.

[0009] The fixed wheel is connected to the wheel via a first screw.

[0010] The power supply assembly includes a coil box connected to the wheel, a magnet box is provided on the brake, a winding coil is provided in the coil box, a permanent magnet is provided in the magnet box, a capacitor is provided on the magnet box, and a temperature control switch is provided on the coil box. The capacitor and the winding coil are electrically connected in parallel, and the winding coil, the temperature control switch and the solenoid valve are electrically connected in series to form a circuit.

[0011] The coil box is annular, and the winding coils are symmetrically arranged on the coil box.

[0012] The wheel is provided with a mounting surface for mounting a coil box, and the mounting surface and the coil box are provided with a receiving groove for placing a temperature control switch.

[0013] The coil box is provided with a mounting seat, and the mounting seat is connected to the wheel via a second screw.

[0014] The magnet box is connected to the brake via a third screw, and the distance between the permanent magnet and the coil winding is 3-5 mm.

[0015] The beneficial effects of the present invention are:

[0016] When the solenoid valve is in normal temperature, it does not work and the solenoid valve return spring causes the shielding plate to close the air vents on the wheel, thereby reducing the wind resistance of the wheel and achieving rapid movement of the wheel. When the brake temperature rises during the braking process of the car and needs to be cooled, the power supply component works to cause the drive component to drive the shielding plate to move on the wheel, so that the air vents on the shielding plate coincide with the air vents on the wheel. The air flow passes through the air vents and the vents to cool the brake, thereby achieving stable use of the brake and higher practicality.

[0017] The power supply assembly consists of a magnet box, coil box, winding coil, and permanent magnet. When the temperature control switch detects that the wheel temperature is above a specified value, the temperature control switch closes. The rotation of the wheel causes the winding coil in the coil box and the permanent magnet in the magnet box to rotate relative to each other, thereby generating electricity through the principle of magnetic field cutting. The current passes through the capacitor and the temperature control switch, activating the solenoid valve, thereby achieving stable rotation of the shielding disk and keeping the vents unobstructed. When the temperature control switch detects that the wheel temperature is below a specified value, the temperature control switch disconnects and cuts off the current. The solenoid valve does not operate, and the solenoid valve's built-in return spring pushes the solenoid valve piston back to its original position, driving the shielding disk to rotate and close the wheel vents. The rotation of the shielding disk is driven by the rotation of the wheel, which is environmentally friendly and more practical. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0030] like Figure 1-9As shown, the low wind resistance wheel includes a wheel 1 and a brake 2 arranged on the wheel 1, the wheel 1 is provided with a ventilation hole 3, the wheel 1 is provided with a shielding plate 4, the shielding plate 4 is provided with an air vent 5, the wheel 1 is provided with a driving component for driving the shielding plate 4 to move, and the wheel 1 is provided with a power supply component for supplying power to the driving component. Specifically, when the ventilation hole 3 and the air vent 5 coincide with each other, the air flow flows through the air vent 5 and the air vent 3 to cool the brake 2.

[0031] When in use, the shielding plate 4 works to close the air vents 3 on the wheel 1, thereby reducing the wind resistance of the wheel 1 and realizing rapid movement of the wheel 1. When the temperature of the wheel 1 rises during the braking process of the car and needs to be cooled, the power supply component works to make the drive component drive the shielding plate 4 to move on the wheel 1, and then the air vents 5 on the shielding plate 4 coincide with the air vents 3 on the wheel 1. The air flow passes through the air vents 5 and the air vents 3 to cool the brake 2, thereby realizing stable use of the brake 2 and higher practicality.

[0032] Reference Figure 1-5 , the driving component includes a solenoid valve 6 arranged on the wheel 1, the piston of the solenoid valve 6 is connected to the shielding plate 4, and the operation of the solenoid valve 6 causes the shielding plate 4 to move, thereby adjusting the position of the air vent 5 on the shielding plate 4, thereby realizing the low wind resistance and temperature reduction control of the wheel 1. In this embodiment, there are two solenoid valves 6, and the two solenoid valves 6 are symmetrically arranged on the wheel 1. The solenoid valve 6 is specifically a LY05 DC push-pull electromagnet. The solenoid valve 6 is connected to the wheel 1 through screws. Specifically, four screws are provided on the periphery of each solenoid valve 6, and the four screws are threaded with the wheel 1. The solenoid valve 6 is fixed by squeezing the solenoid valve 6 by the four screws. Specifically, a return spring is provided on the outer sleeve of the movable end of the solenoid valve 6, so that when the solenoid valve 6 is not working, the piston of the solenoid valve 6 is in an extended state. At this time, the shielding plate 4 closes the air vent 3.

[0033] Reference Figure 5 The piston of the solenoid valve 6 is provided with a hook 18, and the shielding disk 4 is provided with a holder 19 that cooperates with the hook. The solenoid valve 6 can stably drive the shielding disk 4 to move through the cooperation of the hook 18 and the holder 19. Specifically, the cross-section of the holder 19 is a mouth shape, and the cross-section of the hook 18 is U-shaped. The end of the hook 18 is stuck in the holder 19, so that the hook 18 moves the holder 19 as the solenoid valve 6 works, thereby realizing the movement of the shielding disk 4. The holder 19 and the shielding disk 4 are integrally formed, and the hook 18 is connected to the piston of the solenoid valve 6 by screws.

[0034] Reference Figure 3 and 4The shielding plate 4 is annular, and a fixed wheel 7 is provided in the air vent 5 of the shielding plate 4. The fixed wheel 7 is connected to the wheel 1, and a groove 8 is provided on the fixed wheel 7 to engage with the shielding plate 4. The solenoid valve 6 works to make the shielding plate 4 rotate under the support of the fixed wheel 7, thereby realizing stable driving of the shielding plate 4. Specifically, a through hole 401 is provided in the middle position of the shielding plate 4. The setting of the through hole 401 facilitates the stable installation of the shielding plate 4 on the wheel 1. Ten air holes 5 are symmetrically provided on the upper ring of the shielding plate 4. Four fixed wheels 7 are provided in five of the ten air holes 5. The rotation of the shielding plate 4 is limited by the setting of the groove 8 on the fixed wheel 7, thereby ensuring the stable rotation of the shielding plate 4. In this embodiment, the air hole 5 is rectangular, and the fixed wheels 7 on both sides of the air hole 5 fix the shielding plate 4.

[0035] Reference Figure 4 The fixed wheel 7 is connected to the wheel 1 through the first screw 9. The setting of the first screw 9 realizes the stable rotation of the fixed wheel 7 on the wheel 1 and facilitates the convenient disassembly and assembly of the fixed wheel 7. Specifically, a threaded hole that cooperates with the first screw 9 is provided on the wheel 1.

[0036] Reference Figure 1-6 The power supply component includes a coil box 10 connected to the wheel 1, a magnet box 11 is provided on the brake 2, a winding coil 12 is provided in the coil box 10, a permanent magnet 13 is provided in the magnet box 11, a capacitor 14 is provided on the magnet box 11, and a temperature control switch 15 is provided on the coil box 10. The capacitor 14 is electrically connected to the winding coil 12 in parallel, and the winding coil 12, the temperature control switch 15 and the solenoid valve 6 are electrically connected in series to form a circuit. When the wheel 1 rotates, the coil box 10 on the wheel 1 rotates, and then the winding coil 12 in the coil box 10 and the permanent magnet 13 in the magnet box 11 rotate relative to each other, thereby generating electricity through the principle of magnetic field cutting, and stabilizing the current in the circuit through the capacitor 14, and the brake 2 works to generate When the heat is higher than the specified temperature, the temperature control switch 15 is closed, so that the winding coil 12 and the capacitor 14 are connected to the circuit formed by the temperature control switch and the solenoid valve 6. The electricity generated by the winding coil 12 is stabilized by the capacitor 14 and then supplies power to the solenoid valve 6. The solenoid valve 6 works to move the shielding disk 4. In this embodiment, the coil box 10 is annular, and fourteen coil windings 12 and a capacitor 14 are symmetrically arranged in an annular shape on the coil box 10. Six permanent magnets 13 are provided in the magnet box 11. Each coil winding 12 is aligned with two permanent magnets 13. The capacitor 14 is used to stabilize the current in the coil to ensure that the solenoid valve 6 is stable in the open state. In this embodiment, the specific model of the temperature control switch 15 is KSD9700 temperature control switch.

[0037] Specifically, the fourteen coil windings 12 and the capacitor 14 are connected in series to form a closed loop, the capacitor 14 , the solenoid valve 6 and the temperature control switch 15 are connected in series to form a closed loop, and the temperature control switch 15 controls the on and off of the solenoid valve 6 .

[0038] The coil box 10 is annular, and the winding coil 12 is annularly symmetrically arranged on the coil box 10, so as to ensure that the winding coil 12 and the permanent magnet 13 rotate relative to each other when the coil box 1 rotates with the wheel 1, thereby generating current.

[0039] The wheel 1 is provided with a mounting surface 21 for mounting the coil box 10. The mounting surface 21 is used to achieve stable mounting of the coil box 10 on the wheel 1. In this embodiment, the cross-section of the coil box 10 is trapezoidal, and the mounting surface 21 is provided with an inclined surface to ensure that the coil box 10 is stuck on the mounting surface 21. The mounting surface 21 and the coil box 10 are provided with a receiving groove 22 for placing the temperature control switch 15. After the coil box 10 is connected to the wheel 1, the temperature control switch 15 is stuck in the receiving groove 22 between the coil box 10 and the mounting surface 21. The switch 15 is accommodated in the receiving groove 22, so as to facilitate real-time detection of the temperature transmitted from the brake 2 to the wheel 1. Specifically, the temperature control switch 15 is a normally open type of 140°C. When the temperature is less than 140°C, the temperature control switch 15 is not conductive, the solenoid valve 6 is closed, and the shielding plate 4 rotates through the solenoid valve 6 to close the ventilation hole 3, thereby reducing the wind resistance of the wheel 1. When the temperature is greater than 140°C, the temperature control switch 15 is opened, the solenoid valve 6 is energized, and the shielding plate 4 rotates to open the ventilation hole 3, thereby increasing the ventilation volume and reducing the temperature of the brake 2.

[0040] Reference Figure 6 The coil box 10 is provided with a mounting seat 16, which is connected to the wheel 1 through a second screw 17. The coil box 10 is stably installed on the wheel 1 through the mounting seat 16 and the second screw 17. Specifically, there are five mounting seats 16, and the five mounting seats 16 are welded symmetrically on the coil box 10 in an annular manner. A through hole is provided on the mounting seat 16 for the second screw 17 to pass through, and a threaded hole that cooperates with the second screw 17 is provided on the wheel 1.

[0041] The magnet box 11 is connected to the brake 2 by a third screw 20. The distance between the permanent magnet 13 and the coil winding 12 is 3-5 mm, so that the winding coil can stably fit the magnetic field of the permanent magnet. In this embodiment, the distance between the permanent magnet 13 and the coil winding 12 is 4 mm.
