[0039] 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.
[0040] In the present application, the basic structure of the wheel hub includes a rim 1, spokes 2, and a spoke plate 3. There are several spoke plate mounting holes 4 distributed circumferentially on the spoke plate 3. The spokes 2 can realize the connection between the spoke plate 3 and the rim 1, and the rim 1 can realize the installation of the tire.
[0041] The spoke plate 3 is integrally installed with a monitoring sleeve 6 in the space enclosed by the spoke plate mounting hole 4. The monitoring sleeve 6 is opened at the end face away from the spoke plate 3. A monitoring seat cover plate 5 is connected to the opening of the monitoring sleeve 6. The connection between the monitoring seat cover plate 5 and the monitoring sleeve 6 is achieved by fasteners.
[0042] The spoke plate 3 is processed with a stepped hole 16 in the area where the monitoring sleeve 6 is arranged, and 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 guide hole, a limit hole, and a mounting hole. The inner diameter of the guide hole is larger than the inner diameter of the limit hole, and the inner diameter of the limit hole is larger than the inner diameter of the mounting hole. The mounting hole is provided with a push rod 11 that slides relative to it. The outer wall of the push rod 11 contacts the inner wall of the mounting hole. There is a step structure between the limit hole and the mounting hole to achieve the limiting of the limit rod 12 in the limit hole during the resetting process. The circumferential outer wall of the limit rod 12 is in contact with the inner wall of the limit hole and slides relatively. A number of evenly distributed countersunk guide grooves 22 are processed on the inner wall of the guide hole, and the countersunk guide grooves 22 can slide relative to the circumferential protrusions of the guide rod 13.
[0043] The guide rod 13 is coaxially provided with a transmission rod 14 on the end face facing the monitoring seat cover 5, and the transmission rod 14 and the guide rod 13 can rotate relative to each other, that is, a guide shaft is coaxially provided on the guide rod 13, and a guide blind hole is processed on the end face of the spoke plate mounting hole 4, and the guide blind hole is rotatably connected to the guide shaft through a bearing structure.
[0044] In the present application, a reset spring 10 is provided between the end of the transmission rod 14 and the end of the monitoring seat cover 5, and the two ends of the reset spring 10 are respectively connected to the end faces of the transmission rod 14 and the monitoring seat cover 5 through a spring seat body.
[0045] The circumferential side wall of the transmission rod 14 is processed with a spiral transmission groove 15, and the spiral transmission groove 15 is evenly distributed around the central axis of the transmission rod 14. The transmission rod 14 is slidably connected with the inner hole guide rod 19 through the spiral transmission groove 15, and the inner hole guide rod 19 is arranged corresponding to the spiral transmission groove 15, and the contact end surface of the inner hole guide rod 19 and the spiral transmission groove 15 is a smooth end surface. 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 rod 19 is distributed around the inner hole central axis of the rotating plate 17.
[0046] The rotating plate 17 is processed with a plurality of rotating plate driving holes 18 in the circumferential direction, and the rotating plate driving holes 18 are evenly distributed around the central axis of the rotating plate 17. A sufficient gap is left between the circumferential side wall of the rotating plate 17 and the circumferential inner wall of the monitoring sleeve 6.
[0047] The rotating plate 17 drives a sensor slide rod 20 through a rotating plate driving hole 18. A spring mounting rod is coaxially arranged at the top end of the sensor slide rod 20. The spring mounting rod can enable the sensor slide rod 20 and the loose sensor 7 to be relatively limited, and ensure that the sensor slide rod 20 can move relative to the loose sensor 7 under the drive of the rotating plate driving hole 18.
[0048] In the present application, the looseness sensor 7 is processed with a T-shaped groove on the end face facing the sensor slide bar 20, the bottom end opening of the T-shaped groove faces the direction of the sensor slide bar 20, and the shrapnel mounting rod is limited in the T-shaped groove. The shrapnel mounting rod is installed with a metal shrapnel 21 at the top away from the sensor slide bar 20, and the metal shrapnel 21 is in the T-shaped groove and contacts the bottom surface of the T-shaped groove. The bottom surface of the T-shaped groove is provided with several groups of loops composed of paired metal contacts, and the loop signal can be respectively sent to the connected vehicle wiring harness or wireless transmitting unit through the port of the circuit board. When the wireless transmitting unit is configured, the power supply mode of the wireless transmitting unit and the circuit board can be selected as wired or independent battery power supply.
[0049] In the present application, the rotating plate 17 is connected to the cover plate 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 shaft 9. The cover plate shaft 9 is fixed on the monitoring seat cover 5.
[0050] In the case of the above structure, the relative movement relationship of each structure in the present application is that when the spoke plate 3 is installed on the shaft body through the spoke plate mounting hole 4 and the fastening bolts, the push rod 11 can be squeezed into the stepped hole 16 by the disc on the shaft body.
[0051] When the top rod 11 drives the limit rod 12 and the guide rod 13 integrally provided therewith to move into the stepped hole 16, and the guide rod 13 can ensure the movement stability of the limit rod 12 and the top rod 11, the guide rod 13 drives the transmission rod 14 to move in the direction of the rotating plate 17, and 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 itself rotates, and 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, and 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 driving hole 18, and the movement of the sensor slide rod 20 causes it to move relative to the loose sensor 7. The relative movement between the transmission rod 14 and the monitoring seat cover 5 can also squeeze the reset spring 10 disposed therebetween, causing the reset spring 10 to deform.
[0052] When a telescopic rod is provided on the outer circumferential wall of the rotating plate 17, the inner wall end surface of the telescopic rod facing the monitoring sleeve 6 is a smooth structure, and the monitoring sleeve 6 is processed with a contact conduction groove for the telescopic rod to slide in or out, and two contacts that can be conducted by the ends of the telescopic rod are provided in the contact conduction groove, and the contacts are respectively connected to the circuit board of the loose sensor 7 at the corresponding position through wires. The structure in this paragraph can cooperate with the structure of the loose sensor 7, the sensor slide rod 20, and the metal spring 21 to realize mutual correction of signals.
[0053] Specifically, when the bolt in the radial plate mounting hole 4 is loosened, the push rod 11 will be reset under the action of the reset 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 driving hole 18, and the paired contacts in the loose sensor 7 are turned on within a set distance. The conduction of the contacts will make the circuit board stroke loop signal in the loose sensor 7, and the loop signal can be transmitted to the control unit through the vehicle wiring harness or the wireless transmitting unit to realize the alarm. And in the process of the above-mentioned contact conduction in the loose sensor 7, the contact in the corresponding contact conduction groove can be turned on at the same time. The signal in the contact conduction groove can realize mutual verification with the signal in the loose sensor 7, improve the accuracy of signal judgment, and avoid the false alarm of a single signal. Therefore, in the present application, multiple loose sensors 7 and multiple contact conduction grooves are set. When more than half of the contacts are turned on, the signal is judged to be true.
[0054] Finally, although this specification describes the technical solution in the form of the best embodiment, it does not limit the technicians in this field to recombine the technical solutions recorded in this application based on the existing technology they have mastered. Such recombination should be considered to be still within the scope of protection of this application.
