[0025] The structure of the remaining parts is the same as that described in Example 1. Those skilled in the art can understand the technical solution described in this embodiment based on the technical solution described in Example 1.

[0026] Based on the above embodiments, the following paragraphs will continue to describe in detail the technical features involved and the functions and roles played by the technical features in this technical solution, so as to help technical personnel in this field to fully understand the technical solution and reproduce it.

[0027] In this application, if Figures 1 to 2 The figure shows the overall structure of a self-deformation monitoring hub, including a center plate 28 connected to the rim 5 via a plurality of circumferentially distributed spokes 1 to form an integral structure. A center hole 9 is machined in the middle of the center plate 28. Several bolt holes 7 are distributed around the center plate 28 around the center hole 9. The bolt holes 7 are detachably connected to the mounting position via bolts. The bolt holes 7 are located between adjacent spokes 1.

[0028] In the present application, a valve hole 6 is processed on the rim 5 .

[0029] In the present application, the spoke plate 1 is a Y-shaped structure, and a spoke plate reinforcement rib 8 is integrally formed at the edge of the spoke plate 1 .

[0030] In the present application, the spoke plate 1 forms a spoke inner cavity 2 with a similar shape on its inner side according to its shape, and the spoke inner cavity 2 is closed at the opening position by a cover plate with the same shape as the spoke plate 1 .

[0031] A controller 3 is fixedly mounted at the bottom end of the spoke-inner cavity 2 near the center plate 28. The controller 3 includes a signal transmission unit, such as a WiFi signal module, Bluetooth signal module, or IoT module, which can wirelessly transmit detected signals to an onboard control unit. The controller 3 also includes a through hole that connects to the rigid rod 10 and the box connecting rod 14. The box connecting rod 14 is fixedly connected to the through hole. A sliding sleeve is provided at the connection between the rigid rod 10 and the through hole, and the sliding sleeve is fixed to the controller 3.

[0032] In the present application, the top end of the rigid rod 10 is in contact with the rim 5 . Since the spokes 1 are evenly distributed around the circumference of the rim 5 , several rigid rods 10 in the hub structure can monitor the circumferential deformation of the rim 5 .

[0033] In the present application, the bottom end of the rigid rod 10 passes through the sliding sleeve of the controller 3 and extends into the interior of the controller 3, and the bottom end of the rigid rod 10 is connected to the bottom surface of the controller 3 through the reset spring 16. The above structure can achieve the adjustment and reset of the motion range of the rigid rod 10.

[0034] In the present application, the rigid rod 10 is symmetrically processed with a rod tooth-shaped portion 11 on both sides, and the rod tooth-shaped portion 11 extends a certain distance along the length direction of the rigid rod 10. The length of the rod tooth-shaped portion 11 is required to meet the movement displacement of the rigid rod 10 itself and the adjustment of the position of the box sleeve 13 relative to the rigid rod 10.

[0035] In the present application, the rigid rod 10 is transmitted through the toothed portion 11 of the rod body and the structure in the monitoring box body 12 . The monitoring box body 12 is respectively processed with through holes at the top and bottom ends for the rigid rod 10 to pass through.

[0036] The monitoring box body 12 is internally connected to a secondary gear 18 via a shaft. The secondary gears 18 are divided into two groups, each group including two coaxially connected secondary gears 18. The secondary gears 18 in the same group are connected to the primary gear 17 via a shaft. The primary gear 17 is located between the coaxially adjacent secondary gears 18 and meshes with the toothed portion 11 of the rod body for transmission.

[0037] In the present application, the primary gear 17 and the secondary gear 18 have a large transmission ratio, which can amplify the small movement distance of the toothed portion 11 of the rod body. Adjacent secondary gears 18 in different groups are forced to synchronize transmission through synchronization gears 19. The synchronization gears 19 on both sides of the rigid rod 10 are forced to synchronize transmission through a gear synchronization rod 20, which is rotationally connected to the monitoring box body 12.

[0038] In the present application, the hole 15 in the rod body is a bar-shaped through hole, which does not affect the displacement movement of the rigid rod 10 , but enables the rigid rod 10 to move under the guidance of the gear synchronization rod 20 .

[0039] In the present application, the secondary gear 18 is meshed with the monitoring gear 21 for transmission, and the secondary gear 18 and the monitoring gear 21 have a large transmission ratio, so that the secondary gear 18 enables the monitoring gear 21 to rotate a certain angle. This rotation angle will make the displacement of the rigid rod 10 reflected in the swing amplitude of the monitoring pendulum 25. The swing end of the monitoring pendulum 25 is provided with a pendulum transmitting end 26. The pendulum transmitting end 26 is a wire beam light transmitter, and a laser transmitter with a smaller divergence performance can be selected. The light source emitted by the pendulum transmitting end 26 can be irradiated into the corresponding monitoring hole 24, so that the photosensitive element in the monitoring hole 24 can sense the light and form an electrical signal. The PCB circuit board located in the U-shaped plate groove 23 can transmit the photosensitive signal to the corresponding controller 3.

[0040] In this application, there are multiple monitoring holes 24 distributed along the U-shaped plate groove 23, and the distribution range is within the swing path of the rocker transmitting end 26 following the monitoring rocker 25. Different swing amplitudes of the rocker transmitting end 26 correspond to monitoring holes 24 at different locations. The photosensitive elements of different monitoring holes 24 have different codes, and the order in which different codes generate electrical signals is also different. The controller 3 determines the deformation of the wheel hub based on the different codes and the order in which the different codes generate electrical signals.

[0041] In the present application, the monitoring U-shaped plate 22 has a U-shaped plate groove 23 for placing a PCB circuit board. In the present application, the monitoring U-shaped plates 22 are distributed at the four corners of the box sleeve 13 and are symmetrically arranged. The four monitoring U-shaped plates 22 and their internal structures such as the PCB circuit board, the monitoring rocker 25, and the rocker transmitting end 26 can achieve mutual signal correction to avoid false alarms. At the same time, in order to ensure the stability of the gear synchronization rod 21, an auxiliary connecting block 27 can be set inside the monitoring box body 12, and a bearing structure can be provided at the connection point between the auxiliary connecting block 27 and the gear synchronization rod 21.

[0042] The above shows and describes the basic principles, main features and advantages of the present application. However, those skilled in the art should understand that the above embodiments in the present application are merely the most preferred technical solutions and are not intended to limit the scope of protection of the present application. Without departing from the inventive spirit and scope of the present application, those skilled in the art may make changes and improvements to the technical solutions of the present application based on the existing technology they possess, which still fall within the scope of protection of the present application.
