The lifting slide rod 18 can drive the displacement sensor 24 to move, thereby driving the displacement sensor 24 to measure the displacement.

[0034] In the technical solution described in this embodiment, the displacement sensor 24 is connected to the controller via an electrical signal. The controller is located inside the monitoring housing 8 and is connected to a power source via an electrical signal. The power source is a battery and is located inside the monitoring housing 8.

[0035] Example 2: See also Figures 1 to 8Based on Embodiment 1, a new energy vehicle wheel hub with anti-loosening monitoring function is provided. The monitoring housing 8 has a monitoring column 23 integrally formed at its bottom surface. A lifting sleeve 13 is slidably mounted on the monitoring column 23. The lifting sleeve 13 is a hollow cylinder with an open bottom end. A return spring 26 is provided between the lifting sleeve 13 and the monitoring column 23. A sleeve guide shaft 27 is integrally formed on the lifting sleeve 13. A column guide hole 28 is coaxially provided on the monitoring column 23. The sleeve guide shaft 27 slides within the column guide hole 28, and the return spring 26 is sleeved on the sleeve guide shaft 27. A column bearing 22 is provided near the bottom end of the monitoring column 23. The monitoring column 23 is connected to a rotating plate 25 via the column bearing 22. The rotating plate 25 is parallel to the bottom surface of the monitoring housing 8. The rotating plate 25 has driven teeth 20 symmetrically arranged in the circumferential direction. The rotating plate 25 is driven by the driven teeth 20 meshing with the drive gear 16 at the corresponding position. The drive gear 16 has a drive motor, which is connected to the controller and battery, which are also located in the monitoring housing 8. A guide rod 21 is fixedly arranged on the rotating plate 25.

The bottom end of the guide rod 21 is fixedly arranged on the rotating plate 25, and the top end of the guide rod 21 is a smooth ball end. The guide rods 21 are symmetrically arranged on the rotating plate 25.

[0036] In the technical solution described in this embodiment, the monitoring column 23 is fixedly disposed on the bottom surface of the monitoring housing 8, and the monitoring column 23 is a circular column.

[0037] In the technical solution described in this embodiment, the lifting sleeve 13 is a hollow cylinder with an open bottom end. The lifting sleeve 13 is sleeved on the circumferential outer end face of the monitoring column 23, and the lifting sleeve 13 is slidably arranged along the monitoring column 23.

[0038] In the technical solution described in this embodiment, a return spring 26 is provided between the lifting sleeve 13 and the monitoring column 23. The return spring 26 can provide a reset force for the movement of the lifting sleeve 13 relative to the monitoring column 23.

[0039] In the technical solution described in this embodiment, a sleeve guide shaft 27 is coaxially arranged inside the lifting sleeve 13. The sleeve guide shaft 27 can be inserted into the column guide hole 28, which is located at the central axis of the monitoring column 23.

[0040] In the technical solution described in this embodiment, the lifting sleeve 13 is provided with a sleeve thread groove 14 in the circumferential direction. The lifting sleeve 13 drives the guide rod 21 to move through the sleeve thread groove 14. The movement of the guide rod 21 can drive the rotating plate 25 to rotate. The rotating plate 25 realizes the movement around the monitoring column 23 through the column bearing 22.

[0041] In the technical solution described in this embodiment, the guide rod 21 is an L-shaped rod with a spherical smooth end at its top. The bottom end of the guide rod 21 is fixedly mounted on the rotating plate 25, and the guide rod 21 slides along the sleeve thread groove 14 through the spherical smooth end at its top. Since the lifting sleeve 13 can slide relative to the monitoring column 23, this means that the sleeve thread groove 14 will slide relative to the guide rod 21 in the fixed position, thereby driving the guide rod 21 and the rotating plate 25 to move.

[0042] Example 3: See also Figures 1 to 8 Based on Embodiments 1 and 2, a new energy vehicle wheel hub with anti-loosening monitoring function is provided. The rotating plate 25 has a fan-shaped outer plate 19 circumferentially arranged. The fan-shaped outer plate 19 has a narrow end and a wide end. An arc-shaped end face connecting the narrow end and the wide end is provided on the outer end face of the fan-shaped outer plate 19. A micro switch 15 is provided on the path of the fan-shaped outer plate 19 as it rotates with the rotating plate 25. The micro switch 15 is electrically connected to a controller. A housing positioning block 30 is integrally provided on the bottom surface of the monitoring housing 8. The monitoring housing 8 is inserted into a positioning hole 6 through the housing positioning block 30. The positioning hole 6 is located on the bottom surface of the monitoring groove 5. Parallel buffer positioning ribs 9 are integrally provided on the outer circumferential side of the monitoring housing 8. A buffer shell 7 is provided between the parallel buffer positioning ribs 9. The buffer shell 7 is made of elastic material and protrudes from the outer end face of the buffer positioning ribs 9. The monitoring housing 8 contacts the circumferential side of the monitoring groove 5 through the buffer shell 7. The monitoring housing 8 is provided with a housing connecting post 12 at the circumferential corner position. The monitoring housing 8 is hinged to the top cover 10 through the housing connecting post 12. The top cover 10 is provided with a top cover through hole 11. The housing connecting post 12 has a connecting hole corresponding to the top cover through hole 11. The two connecting holes are connected to the top cover 10 and the monitoring housing 8 by hinge.

[0043] In the technical solution described in this embodiment, the fan-shaped outer plate 19 can cooperate with the micro switch 15 to realize the start and stop control of the motor in the drive gear 16, and can also feed the signal back to the controller to realize the monitoring of the anti-loosening function.

[0044] In use, this application employs a microcontroller as the controller and a battery as the power source. The controller is electrically connected to the displacement sensor 24, the microswitch 15, and the drive motor of the drive gear 16 via electrical signals. The controller includes a wireless signal transmitter to facilitate pairing with a receiver on the vehicle and to achieve feedback of the monitoring signal.

[0045] During use, the top end face of the lifting sleeve 13 needs to be pressed flush with the top cover 10 at the installation position. At this time, the controller records the displacement sensor 24 at the position of the lifting slide rod 18 as the initial position, and the drive motor on the drive gear 16 is in a de-energized state. The controller starts the drive motor of the drive gear 16 at fixed time intervals. The drive gear 16 can drive the rotating plate 25 to rotate through the driven gear 20 meshing with it. If the rotating plate 25 can rotate, it will drive the integrally set arc-shaped rotating plate 17 to move. The arc-shaped rotating plate 17 can drive the lifting slide rod 18 to move, and the lifting slide rod 18 will drive the displacement sensor 24 on the side of the monitoring housing 8 to move. At this time, the displacement sensor 24 can realize the displacement measurement of the movement of the lifting slide rod 18, and the displacement sensor 24 can feed back the measured signal to the controller. If the rotating plate 25 is in a large rotation angle range, the fan-shaped outer plate 19 will move with the rotating plate 25. During the rotation with the rotating plate 25, the fan-shaped outer plate 19 will touch the micro switch 15. After being touched, the micro switch 15 will transmit a signal to the controller. After receiving the signal, the controller will send an alarm signal to the outside to remind the driver and passengers to check in time.

[0046] However, if the connection position is not loose, the drive gear 16 will not drive the driven gear 20 that meshes with it to rotate. This is mainly because the top of the guide rod 21 is limited in the sleeve thread groove 14, and the sleeve thread groove 14 is located on the circumferential side of the lifting sleeve 13. The lifting sleeve 13 is limited at the top contact position and there will be no axial displacement of the lifting sleeve 13 relative to the monitoring column 23.

[0047] Finally, although this application explains and illustrates the technical solutions of this application through preferred embodiments, those skilled in the art can rearrange and combine the technical solutions based on their prior art. Such rearrangements and combinations of the technical solutions should be understood as extensions of the scope of protection of this application and are protected by this application.
