[0023] 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 the present technical solution, so as to help technicians in this field to fully understand the technical solution and reproduce it.

[0024] In this application, if Figure 1 to Figure 2 As shown, it shows the overall structure of a deformation self-monitoring hub, including a center plate 28, which is connected to the rim 5 through a plurality of circumferentially distributed spokes 1 to form an integral structure, a center hole 9 is processed at the middle position of the center plate 28, and a plurality of bolt holes 7 are distributed at the center plate 28 position circumferentially of the center hole 9, and the bolt holes 7 are connected to the installation position through a bolt structure to realize a detachable connection of the hub. The bolt holes 7 are located between adjacent spokes 1.

[0025] In the present application, a valve hole 6 is processed on the rim 5 .

[0026] In the present application, the spoke plate 1 is a Y-shaped structure, and a spoke plate reinforcing rib 8 is integrally formed at the edge of the spoke plate 1 .

[0027] In the present application, the spoke plate 1 forms a spoke built-in cavity 2 of similar shape on the inner side according to its shape, and the spoke built-in cavity 2 is closed at the opening position by a cover plate of the same shape as the spoke plate 1 .

[0028] The spoke built-in cavity 2 is fixedly provided with a controller 3 at the bottom near the center plate 28. The controller 3 has a transmitting unit for signal transmission. The transmitting unit is a WiFi signal module, a Bluetooth signal module, an Internet of Things module, etc. in the prior art, which can transmit the monitored signal to the vehicle control unit in a wireless transmission manner. The controller 3 also has a through hole connected to the rigid rod 10 and the box body connecting rod 14. The box body connecting rod 14 is fixedly connected to the through hole. A sliding sleeve is provided at the connection position between the rigid rod 10 and the through hole, and the sliding sleeve is fixed on the controller 3.

[0029] 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 , a plurality of rigid rods 10 in the hub structure can monitor the circumferential deformation of the rim 5 .

[0030] In the present application, the bottom end of the rigid rod 10 passes through the sliding sleeve of the controller 3 and then 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.

[0031] In the present application, the two sides of the rigid rod 10 are symmetrically processed with rod tooth-shaped parts 11, and the rod tooth-shaped parts 11 extend a certain distance along the length direction of the rigid rod 10. The length of the rod tooth-shaped parts 11 must 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.

[0032] 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.

[0033] The monitoring box body 12 is internally connected to a secondary gear 18 through a shaft body, and the secondary gear 18 is divided into two groups, each group including two coaxially connected secondary gears 18. The secondary gears 18 in the same group are connected to a primary gear 17 through a shaft body, and the primary gear 17 is located between the coaxially adjacent secondary gears 18, and the primary gear 17 is meshed with the toothed portion 11 of the rod body for transmission.

[0034] In the present application, the primary gear 17 and the secondary gear 18 have a large transmission ratio, which can realize the amplification of the small movement distance of the rod body toothed portion 11, and the adjacent secondary gears 18 in different groups realize forced synchronous transmission through the synchronous gear 19. The synchronous gears 19 on both sides of the rigid rod 10 realize forced synchronous transmission through the gear synchronization rod 20, and the gear synchronization rod 20 is rotatably connected to the monitoring box body 12.

[0035] In the present application, the hole 15 in the rod body is a bar-shaped through hole, which will not affect the displacement movement of the rigid rod 10 , but can enable the rigid rod 10 to move under the guidance of the gear synchronization rod 20 .

[0036] 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, and 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, and the PCB circuit board located in the U-shaped board groove 23 can transmit the photosensitive signal to the corresponding controller 3.

[0037] In the present application, there are a plurality of monitoring holes 24 distributed along the U-shaped plate groove 23, and the distribution range is the swing path of the swing rod transmitting end 26 following the monitoring swing rod 25. Different swing amplitudes of the swing rod transmitting end 26 correspond to monitoring holes 24 at different positions, and the photosensitive elements of different monitoring holes 24 have different codes, and the order of generating electrical signals of different codes is also different. The controller 3 determines the deformation of the wheel hub according to the different codes and the order of generating electrical signals of different codes.

[0038] In the present application, the monitoring U-shaped plate 22 has a U-shaped plate groove 23 for placing the 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 the structures arranged inside them, such as the PCB circuit board, the monitoring swing rod 25, and the swing rod transmitting end 26, can realize mutual correction of signals to avoid false alarms. At the same time, in order to ensure the stability of the gear synchronization rod 21, an auxiliary connection block 27 can be arranged inside the monitoring box body 12, and a bearing structure can be arranged at the connection position between the auxiliary connection block 27 and the gear synchronization rod 21.

[0039] The above shows and describes the basic principles, main features and advantages of the present application, but those skilled in the art should understand that the above embodiments in the present application are only the most preferred technical solutions and are not used to limit the scope of protection of the present application. Without departing from the inventive spirit and scope of the present application, the changes and improvements made to the technical solutions of the present application by those skilled in the art based on the existing technologies they have mastered still fall within the scope of protection of the present application.
