[0041] On the basis of the above embodiments, the following paragraphs are used to continue to describe in detail the technical features involved and the functions and roles played by these technical features in the technical solution, so as to help those skilled in the art fully understand the technical solution and reproduce it.
[0042] In this application, the basic components of the wheel hub include a rim 1, a spoke 2, and a web 3. A plurality of web mounting holes 4 are circumferentially distributed on the web 3. The spoke 2 can connect the web 3 and the rim 1, and the rim 1 can mount a tire.
[0043] A monitoring sleeve 6 is integrally installed in the space surrounded by the web mounting holes 4 on the web 3. The monitoring sleeve 6 has an opening at the end far from the web 3. A monitoring seat cover plate 5 is connected to the opening of the monitoring sleeve 6, and the connection between the monitoring seat cover plate 5 and the monitoring sleeve 6 is achieved through fasteners.
[0044] A stepped hole 16 is machined in the area surrounded by the monitoring sleeve 6 on the web 3. The stepped hole 16 is coaxially arranged with the monitoring sleeve 6. The stepped hole 16 is composed of three coaxially arranged hole bodies, namely a guiding hole, a limiting hole, and a mounting hole. The inner diameter of the guiding hole is larger than that of the limiting hole, and the inner diameter of the limiting hole is larger than that of the mounting hole. A push rod 11 that slides relative to it is arranged in the mounting hole. The outer side wall of the push rod 11 contacts the inner wall of the mounting hole. A step structure is formed between the limiting hole and the mounting hole to limit the limiting rod 12 during the reset process in the limiting hole. The circumferential outer side wall of the limiting rod 12 is in contact with and slides relative to the inner wall of the limiting hole. A plurality of evenly distributed counterbore guiding grooves 22 are machined on the inner wall of the guiding hole, and the counterbore guiding grooves 22 can slide relative to the protrusions on the circumferential direction of the guiding rod 13.
[0045] A transmission rod 14 is coaxially arranged on the end face of the guiding rod 13 facing the monitoring seat cover plate 5. The transmission rod 14 and the guiding rod 13 can rotate relative to each other, that is, a guiding rotating shaft is coaxially arranged on the guiding rod 13. A guiding blind hole is machined on the end face of the web mounting hole 4, and the guiding blind hole is rotationally connected to the guiding rotating shaft through a bearing structure.
[0046] In this application, a return spring 10 is arranged between the end of the transmission rod 14 and the end of the monitoring seat cover plate 5. The two ends of the return spring 10 are respectively connected to the end faces of the transmission rod 14 and the monitoring seat cover plate 5 through spring seat bodies.
[0047] A spiral drive groove 15 is machined on the circumferential side wall of the drive rod 14, and the spiral drive grooves 15 are evenly distributed around the central axis of the drive rod 14. The drive rod 14 is slidably connected to the inner hole guide rod 19 through the spiral drive groove 15. The inner hole guide rod 19 is correspondingly arranged with the spiral drive groove 15, and the contact end face between the inner hole guide rod 19 and the spiral drive groove 15 is a smooth end face. The inner hole guide rod 19 is fixedly installed on the inner hole side wall of the rotating plate 17, and the inner hole guide rods 19 are distributed around the central axis of the inner hole of the rotating plate 17.
[0048] A plurality of rotating plate drive holes 18 are machined in the circumferential direction of the rotating plate 17, and the rotating plate drive holes 18 are evenly distributed around the central axis of the rotating plate 17. There is enough clearance between the circumferential side wall of the rotating plate 17 and the circumferential inner wall of the monitoring sleeve 6.
[0049] The rotating plate 17 drives a sensor slide rod 20 through the rotating plate drive hole 18. A shrapnel mounting rod is coaxially arranged at the top end of the sensor slide rod 20. The shrapnel mounting rod can limit the relative position between the sensor slide rod 20 and the looseness sensor 7, and ensure that the sensor slide rod 20 can move relative to the looseness sensor 7 under the drive of the rotating plate drive hole 18.
[0050] In the present application, a T-shaped groove body is machined on the end face of the looseness sensor 7 facing the sensor slide rod 20. The bottom end opening of the T-shaped groove body faces the direction where the sensor slide rod 20 is located, and the shrapnel mounting rod is limited in the T-shaped groove body. A metal shrapnel 21 is installed at the top end of the shrapnel mounting rod away from the sensor slide rod 20. The metal shrapnel 21 is in the T-shaped groove body and contacts the bottom surface of the T-shaped groove body. Several groups of circuits composed of paired metal contacts are arranged on the bottom surface of the T-shaped groove body. The signals of this circuit can be sent into the connected vehicle wiring harness or wireless transmission unit respectively through the ports of the circuit board. When a wireless transmission unit is configured, the power supply mode of the wireless transmission unit and the circuit board can be selected as wired or independent battery power supply.
[0051] In the present application, the rotating plate 17 is connected to the cover plate rotating shaft 9 through a plurality of rotating plate connecting plates 8 fixedly arranged at the inner hole position. A bearing structure is arranged at the connection position between the rotating plate connecting plate 8 and the cover plate rotating shaft 9. The cover plate rotating shaft 9 is fixed on the monitoring seat cover plate 5.
[0052] In the case of the above structure, the relative movement relationship of each structure in the present application is as follows: when the spoke plate 3 is installed on the shaft body through the spoke plate mounting hole 4 and the fastening bolt, the ejector rod 11 can be squeezed into the stepped hole 16 by the disc body on the shaft body.
[0053] The ejector rod 11 drives the limit rod 12 and the guide rod 13 integrally provided therewith to move into the stepped hole 16. The guide rod 13 can ensure the movement stability of the limit rod 12 and the ejector rod 11. The guide rod 13 drives the transmission rod 14 to move in the direction of the rotating plate 17. The transmission rod 14 contacts the inner hole guide rod 19 on the rotating plate 17 through the spiral transmission groove 15. When the transmission rod 14 moves in the direction of the monitoring seat cover plate 5, due to the interaction between the spiral transmission groove 15 and the inner hole guide rod 19, the transmission rod 14 rotates itself. The inner hole guide rod 19 also moves under the drive of the spiral transmission groove 15 and drives the rotating plate 17 to rotate together. The rotating plate 17 rotates around the cover plate rotating shaft 9 through the rotating plate connecting plate 8. The rotation of the rotating plate 17 can drive the corresponding sensor slide rod 20 to move through the rotating plate drive hole 18. The movement of the sensor slide rod 20 causes a relative movement between it and the loose sensor 7. The relative movement between the transmission rod 14 and the monitoring seat cover plate 5 can also squeeze the return spring 10 provided therebetween, causing the return spring 10 to deform.
[0054] When the outer circumferential wall of the rotating plate 17 is provided with a telescopic rod, the end face of the telescopic rod facing the inner wall of the monitoring sleeve 6 is a smooth structure. The monitoring sleeve 6 is processed with a contact conduction groove for the telescopic rod to slide in or out. Two contacts that can be conducted by the end of the telescopic rod are arranged in the contact conduction groove. The contacts are respectively connected to the circuit board of the loose sensor 7 at the corresponding positions through wires. The structure in this paragraph can cooperate with the structures of the loose sensor 7, the sensor slide rod 20, and the metal elastic sheet 21 to realize the mutual correction of signals.
[0055] Specifically, when the bolt in the spoke mounting hole 4 becomes loose, the ejector rod 11 will reset under the action of the return spring 10. During the reset process, the transmission rod 14 will drive the rotating plate 17 to rotate through the spiral transmission groove 15 and the inner hole guide rod 19. The rotating plate 17 drives the sensor slide rod 20 to return to a certain position along the loose sensor 7 through the rotating plate drive hole 18 and conduct the paired contacts in the loose sensor 7 within a set distance. The conduction of the contacts will cause the circuit board in the loose sensor 7 to form a loop signal. This loop signal can be transmitted to the control unit through the vehicle wiring harness or the wireless transmission unit to realize an alarm. And during the conduction of the above contacts in the loose sensor 7, the contacts in the corresponding contact conduction groove can be conducted together. The signal in the contact conduction groove can be mutually verified with the signal in the loose sensor 7 to improve the accuracy of signal judgment and avoid false alarms of a single signal. Therefore, in this application, multiple loose sensors 7 and multiple contact conduction grooves are provided. When more than half of the contacts are conducted, the signal is determined to be true.
[0056] Finally, although this specification describes the technical solution in the manner of the best embodiments, it does not limit those skilled in the art to recombine the technical solution recorded in this application under the circumstances of the prior art they have mastered. Such recombination should be considered to be still within the protection scope of this application.
