Specific implementation mode

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Embodiment 1: Please refer to Figures 1 - 4 , a safety wheel hub for preventing tire detachment, including a wheel hub 1. Both ends of the wheel hub 1 are connected with a fastening disc 2 through fastening bolts 3. The fastening disc 2 is provided with a plurality of guide rods 4 evenly distributed in a ring shape. The guide rods 4 are jointly slidably installed with a limiting plate 5. A first elastic member 6 for resetting the limiting plate 5 is sleeved on the guide rods 4. Both ends of the first elastic member 6 are respectively connected with the guide rods 4 and the limiting plate 5. A protective sleeve 22 is sleeved on the guide rods 4. The first elastic member 6 is located inside the protective sleeve 22. The protective sleeve 22 can prevent external objects from being caught in the gap between the first elastic members 6 and avoid these objects from hindering the normal movement of the first elastic member 6. A first guide frame 7 is fixedly connected to the fastening disc 2. A pressure plate 9 is slidably installed on the first guide frame 7 through four slide blocks 8. The pressure plate 9 is provided with four extrusion blocks 901 that are in contact and cooperation with the limiting plate 5. The surface of the extrusion block 901 in contact and cooperation with the limiting plate 5 is designed as an inclined surface, so that the limiting plate 5 can move downward along the inclined surface of the extrusion block 901. A tensile spring 10 is connected between each slide block 8 and the first guide frame 7. A tire 11 is installed on the wheel hub 1. The tire 11 is provided with a groove corresponding to the limiting plate 5. By engaging the limiting plate 5 into the groove, the fixation of the wheel hub 1 and the tire 11 is achieved.

[0025] In the initial state, due to the action of the tension spring 10, the pressure plate 9 is located at a specific position. At this time, the extrusion block 901 on the pressure plate 9 will extrude the limit plate 5, and the first elastic member 6 is compressed accordingly, causing the limit plate 5 to move downward and snap into the corresponding groove on the tire 11, thereby fixing the tire 11 to the wheel hub 1, effectively preventing relative sliding or tire detachment between the tire 11 and the wheel hub 1, thus improving the service life and safety of the wheel hub 1. When the tire 11 needs to be disassembled, rotate the pressure plate 9 counterclockwise again to relieve the pressure of the extrusion block 901 on the limit plate 5. At this time, the tension spring 10 will be stretched. Then, under the reset elastic force of the first elastic member 6, the limit plate 5 will move upward and withdraw from the groove of the tire 11 to complete the unlocking operation, so that the tire 11 can be easily removed.

[0026] Embodiment 2: On the basis of Embodiment 1, please refer to Figure 5 , a support seat 12 is fixedly connected to the fastening plate 2. A through hole is provided on the support seat 12, and the fastening bolt 3 passes through this through hole. A second guide frame 13 is fixedly connected to the support seat 12. A limit disk 14 is slidably arranged on the second guide frame 13. A through hole is also provided on the limit disk 14. In the initial state, the through hole on the limit disk 14 is offset from the through hole on the support seat 12 to fix the fastening bolt 3. A second elastic member 15 for resetting the limit disk 14 is sleeved on the second guide frame 13.

[0027] When the wheel hub 1 is moving, the limit disk 14 is used to firmly press the fastening bolt 3 to prevent the fastening bolt 3 from loosening due to the vibration of the wheel hub 1. When the connection condition of the fastening bolt 3 needs to be detected, rotate the limit disk 14 clockwise. At this time, the second elastic member 15 is compressed accordingly, and the through hole on the limit disk 14 is aligned with the through hole on the support seat 12, so that the fastening bolt 3 is exposed for easy inspection and maintenance.

[0028] Please refer to Figure 6 , an external tire pressure monitor 16 with functions of monitoring tire pressure and giving early warnings is arranged on the inner ring of the wheel hub 1. An installation seat 17 is arranged on the inner ring of the wheel hub 1. A controller 18 is arranged on the installation seat 17. An intelligent air pump 19 is installed on the installation seat 17. One end of an air charging pipe 20 is connected to the air outlet end of the intelligent air pump 19, and the other end of the air charging pipe 20 is communicated with the air filling port of the tire 11. A protective shell 21 is arranged outside the intelligent air pump 19, and the protective shell 21 is used to protect the intelligent air pump 19 from being damaged by external environmental factors such as dust, moisture, and stones.

[0029] During the operation of the wheel hub 1, the external tire pressure monitor 16 monitors the air pressure inside the tire 11 in real time. If the detected pressure value is lower than the normal pressure range, it indicates that there may be a leakage in the tire 11. At this time, the controller 18 will activate the intelligent air pump 19. The intelligent air pump 19 inhales and compresses the external air and then injects it into the tire 11 through the air filling pipe 20 to complete the automatic inflation operation. When the air pressure in the tire 11 reaches the preset normal range, the controller 18 will operate the intelligent air pump 19 to stop working.

[0030] Although the present invention has been described with reference to exemplary embodiments, it should be understood that the present invention is not limited to the disclosed exemplary embodiments. The scope of the following claims should be given the broadest interpretation so as to cover all variations and equivalent structures and functions.
