[0023] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0024] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0025] This embodiment mainly describes a modular design for automotive wheel hubs, as detailed below:

[0026] like Figure 1 As shown, a modularly designed automobile wheel hub includes a transmission component 7 and a wheel hub assembly. The wheel hub assembly is fixedly mounted on the transmission component 7, and the transmission component 7 is connected to the automobile. The automobile drives the wheel hub assembly to operate through the transmission component 7.

[0027] like Figure 5 As shown, the wheel hub assembly includes an outer rim 1 and an inner rim 3, which are detachably connected together. Specifically, the outer rim 1 is provided with a first protruding edge 19, which extends inward to the inner side of the outer rim 1. The first protruding edge 19 is provided with a plurality of first through holes 20. The inner rim 3 is provided with a second protruding edge 10, which is provided with a second through hole 11 corresponding to the first protruding edge 19. The first protruding edge 19 and the second protruding edge 10 abut against each other, and are fixedly connected by bolts passing through the first through holes 20 and the second through holes 11 simultaneously.

[0028] like Figures 2-4As shown, further, the inner side of the second protruding edge 10 abuts against the side baffle 4. Specifically, the side baffle 4 is provided with a third protruding edge 17, which extends outward and is provided with a third through hole 16 corresponding to the first protruding edge 19. The bolt passes through the first through hole 20, the second through hole 11 and the third through hole 16 at the same time, and fixes the side baffle 4 to the outer wheel rim 1 and the inner wheel rim 3 at the same time.

[0029] The side baffle 4 is also provided with a connecting part 15. Specifically, the connecting part 15 extends inward and is provided with several screw holes. The outer side of the transmission component 7 is provided with an opening corresponding to the screw holes. After the side baffle 4 is fixed, the bolt passes through the screw holes and the opening at the same time to fix the side baffle 4 a second time, making the side baffle 4 more stable when the car is moving. After the connecting part 15 on the side baffle 4 is fixed, it fits against the outer side of the transmission component 7, preventing foreign objects splashed up during the car from directly colliding with the transmission component 7 and causing damage to the transmission component 7.

[0030] like Figure 8 As shown, a fixing ring 2 is provided between the outer rim 1 and the inner rim 3. The fixing ring 2 surrounds the outer rim 1 and the inner rim 3. The edge of the fixing ring 2 extends downward and abuts against the outer rim 1 and the inner rim 3 respectively, so that the fixing ring 2 forms a closed space between the outer rim 1 and the inner rim 3. The closed space covers the connection position of the first protruding edge 19 and the second protruding edge 10, preventing foreign objects from getting stuck in the connection gap between the first protruding edge 19 and the second protruding edge 10.

[0031] A locking device is provided on the inner side of the fixing ring 2. The fixing ring 2 is pressed tightly against the outer wheel rim 1 and the inner wheel rim 3 by the locking device. Specifically, the locking device includes a first locking plate 28, a second locking plate 30 and a lock body 29. The first locking plate 28 and the second locking plate 30 are rotatably connected to both ends of the lock body 29 by a pin.

[0032] The fixed ring 2 is a non-closed loop. The fixed ring 2 has a cross section, specifically, the cross section includes a first cross section 13 and a second cross section 14. The lock body 29 is located at the port of the first cross section 13.

[0033] A mounting base 5 is provided at the port of the first section 13. The other end of the mounting base 5 is located away from the first section 13, and the mounting base 5 protrudes outward from the fixing ring 2, so that the pin and the lock body 29 can be positioned between the mounting base 5 and the inner wheel rim 3.

[0034] After the first locking plate 28 is rotatably connected to the lock body 29 by a pin, the other end is fixedly mounted on the inner wall of the fixing ring 2 away from the first section 13 by two rivets. After the second locking plate 30 is rotatably connected to the lock body 29 by a pin, the other end is fixedly mounted on the second section 14 by two rivets. Through the fixed connection between the first locking plate 28 and the second locking plate 30, the fixing ring 2 is locked between the outer wheel rim 1 and the inner wheel rim 3.

[0035] like Figure 7 As shown, a pressure gauge is installed on the transmission component 7, which allows users to monitor tire pressure changes in real time and prevent tire blowouts due to tire pressure issues.

[0036] The pressure gauge is equipped with a valve body 24, an air inlet pipe 9 and an air outlet pipe 27. A fixed seat 25 is fixedly installed on the valve body 24. The fixed seat 25 abuts against the outer wheel rim 1 and is tightened by bolts. After tightening, the pressure gauge is fixedly installed on the outer wheel rim 1 through the fixed seat 25.

[0037] An intake pipe 9 and an outlet pipe 27 are connected to the valve body 24. A pin 8 is installed inside the valve body 24. One end of the intake pipe 9 is inserted into the valve body 24 and rests against the pin 8. A pressure sensor is installed inside the transmission component 7. The outlet pipe 27 is fixedly connected to the pressure sensor. When the tire pressure of the car tire increases, the intake pipe 9 pushes out the pin 8, the gas flow in the outlet pipe 27 increases, and the pressure sensor detects the increase in tire pressure. When the tire pressure of the car tire decreases, the gas flow in the intake pipe 9 decreases, the pin 8 retracts inward, the gas flow in the outlet pipe 27 decreases, and the pressure sensor detects the decrease in tire pressure.

[0038] An outer casing 23 is provided outside the air outlet pipe 27. The outer casing 23 is made of rubber material and is fixedly installed on the transmission component 7 to protect the air outlet pipe 27 and prevent it from being damaged by foreign objects splashed during the movement of the car.

[0039] The intake pipe 9 passes through the wheel hub assembly and is connected to the car tire. Specifically, a through hole 21 is provided on the first convex edge 19 of the outer wheel rim 1, and a notch 22 is provided on the second convex edge 10 that abuts against the first convex edge 19. The notch 22 is rectangular and extends into the inner wheel rim 3. A groove 18 is provided on the third convex edge 17 that abuts against the inner wall of the second convex edge 10. The through hole 21, the notch 22 and the groove 18 abut against each other to form a channel for the air supply pipe 27 to pass through the wheel hub assembly.

[0040] The end of the air outlet pipe 27 is provided with a valve core 26, and the fixing ring 2 is provided with an outwardly protruding mounting seat 6. The mounting seat 6 is provided with a limit hole 12, and the valve core 26 is located in the limit hole 12 to facilitate monitoring the pressure changes of the car tires.

[0041] like Figure 3As shown, the mutual abutment of the through hole 21, the notch 22 and the slot 18 also provides a positioning function for the user when assembling the wheel hub assembly, making it easy for the user to quickly find the correct assembly position.
