Description

An online tire pressure monitoring and matching device and its process Technical Field

[0001] This invention relates to the field of tire pressure monitoring and matching technology, and in particular to an online tire pressure monitoring and matching device and its process. Background Technology

[0002] With the development of automotive technology, tire pressure monitoring systems have been widely used in automobiles. Tire pressure monitoring monitors the working environment of the car tires, obtains tire pressure and temperature information, and determines whether the tires are working properly based on this information. If the tires are not working properly, the tire pressure monitoring system will issue an alarm to reduce tire wear and improve driving safety.

[0003] Based on the above, existing tire pressure monitoring matching equipment and processes have the following shortcomings:

[0004] When the tire pressure monitoring system (TPMS) installed on the wheel hub needs to be matched and learned during mixed-line production of automobiles, since the wheel hub and tire have already been assembled and the wheel hub size and materials are different, it is not guaranteed that the wheel hub is in a relative state when the TPMS is learned and activated with the matching device. Therefore, there will be problems such as the distance being too far or the position being inaccurate during scanning, which will lead to the inability to complete the corresponding matching learning. Summary of the Invention

[0005] This disclosure relates to an online tire pressure monitoring system (TPMS) matching device and its process. The device controls the rotation of a bidirectional threaded rod through the cooperation of a twin-screw drive and a transmission wheel assembly. This bidirectional threaded rod controls the distance between two matching detection rods, allowing the TPMS to be matched and learned from both the inner and outer sides of the tire wheel hub. This enables the matching of mixed-line TPMS to the TPMS based on the different electromagnetic wave reflection and absorption capabilities of different wheel hub materials, thus improving the accuracy of the TPMS after installation on the vehicle.

[0006] In a first aspect, this disclosure provides an online tire pressure monitoring and matching device and its process, specifically comprising: a device frame; a translational slide is slidably connected to the bottom of the right side wall of the device frame, a tire bracket is slidably connected to the right side wall of the translational slide, a one-way threaded rod is rotatably connected to the right side wall of the translational slide, a transmission wheel set is connected to the top of the one-way threaded rod, a single screw drive motor is fixedly installed on the top of the right side wall of the translational slide, a tire fixing shaft is rotatably connected to the top of the front side of the right side wall of the device frame, a locking nut is threadedly connected to the right end of the tire fixing shaft, a drive motor is fixedly installed on the right side wall of the device frame behind the tire fixing shaft, a transmission gear is fixedly connected to the right end of the drive shaft of the drive motor, and a detection matching rod is slidably connected to the right side wall of the device frame, the left end of the detection matching rod is threadedly connected to the two-way threaded rod.

The bottom of the translation slide is provided with sliding balls in a rectangular array.

[0009] Furthermore, the translation slide is L-shaped, with a rectangular guide groove in the right side wall of the translation slide, and an embedded groove in the bottom left side of the guide groove. The shape of the embedded groove matches the tire bracket. Two guide rods are symmetrically arranged on the front and rear sides of the guide groove. A one-way threaded rod is rotatably connected in the middle of the upper and lower side walls of the guide groove. The top of the one-way threaded rod is connected to the right side of the transmission wheel set and the single screw drive motor. A fixing post is fixedly installed on the top rear side of the translation slide.

[0010] Furthermore, the tire bracket is U-shaped, and two guide sliding holes are symmetrically opened in the upper and lower side walls of the right end of the tire bracket. The guide sliding holes are slidably connected to the guide sliding rod in the guide sliding groove of the right side wall of the translation slide. The middle of the upper and lower side walls of the right end of the tire bracket is threadedly connected to a one-way threaded rod.

[0011] Furthermore, a counterweight block is fixedly connected to the left end of the tire fixing shaft and rotatably connected to the equipment frame. A driven gear and a transmission gear on the rear side are meshed on the left side wall of the tire fixing shaft. Ten fixing threaded holes are arranged in a ring array on the right side wall of the tire fixing shaft, and the fixing threaded holes are connected to the positioning screw at the left end of the positioning column.

[0012] Furthermore, a shaft fixing protrusion is provided in the middle of the right side wall of the tire fixing shaft, and a locking screw is fixedly connected in the middle of the right side wall of the shaft fixing protrusion. A locking nut is threaded onto the locking screw, and two control levers are symmetrically provided on the right side wall of the locking nut.

[0013] Furthermore, a "convex" shaped control slide is provided in the right side wall of the equipment frame. A bidirectional threaded rod is rotatably connected to the left side of the upper and lower end faces of the control slide. A transmission wheel set is connected to the bottom of the bidirectional threaded rod. A twin-screw drive is connected to the left side of the transmission wheel set. The twin-screw drive is fixedly installed on the bottom left side of the control slide.

[0014] Furthermore, two detection matching rods are symmetrically arranged. The left ends of the two detection matching rods are respectively threaded to the upper and lower ends of the bidirectional threaded rod. The left ends of the detection matching rods are slidably connected to the control slide groove of the equipment frame. Long strip-shaped TPMS matching probes are provided on the upper and lower side walls of the two detection matching rods.

[0015] The present invention discloses a process for using an online tire pressure monitoring and matching device, comprising the following steps:

[0016] 1) First, roll the tire assembly onto the translation slide. Then, control the one-way screw rod to rotate in both directions through the cooperation of the drive shaft and transmission wheel set of the single screw drive motor. This one-way screw rod controls the tire carrier to lift and lower on the translation slide.

[0017] 2) Then, the electric telescopic rod and the translating slide are connected at the bottom of the right side wall of the equipment frame. The electric telescopic rod can control the translating slide to slide left and right. With the cooperation of the sliding ball bearings at the bottom of the translating slide, the translating slide can slide smoothly. According to the usage requirements, the translating slide and the tire carrier can support the tire that needs to be matched for tire pressure and bring it close to the equipment frame, which is convenient for lifting and changing the entire tire set.

[0018] 3) Then, when the tire assembly, supported by the translation carriage and tire carrier, reaches the right side of the tire fixing axle and the wheel hub is fitted onto the tire fixing axle, the positioning pin is passed through according to the number of wheel hub fixing holes and connected to the corresponding fixing threaded hole through the positioning screw. The wheel hub can be fixed according to different models of wheel hubs and the number of fixing holes. The wheel hub can be better fixed by locking the nut, and the wheel hub can be prevented from falling off when rotating.

[0019] 4) Then, the tire fixed shaft is driven by the drive motor through the meshing of the driven gear and the transmission gear. At the same time, when the wheel hub of the tire group is close to the right side wall of the equipment frame, the double screw drive and the transmission wheel group control the rotation of the bidirectional screw rod. The distance between the two detection matching rods can be controlled by the bidirectional screw rod, so that the tire pressure monitoring equipment can be matched and learned from the inner and outer sides of the wheel hub of the tire group. In this way, the TPMS produced on the mixed production line can be matched to the tire pressure monitoring equipment according to the different electromagnetic wave reflection and absorption capabilities of different wheel hub materials, which facilitates the improvement of the accuracy of the tire pressure monitoring equipment after it is installed in the vehicle.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. The single-screw drive mechanism, through the cooperation of its drive shaft and transmission wheel set, controls the forward and reverse rotation of the unidirectional screw rod. This unidirectional screw rod then controls the lifting and lowering of the tire carrier on the translation slide. Connected to the translation slide by an electric telescopic rod located at the bottom of the right side wall of the equipment frame, the electric telescopic rod controls the left and right sliding of the translation slide. With the assistance of sliding ball bearings at the bottom of the translation slide, smooth sliding is achieved. This allows the translation slide and tire carrier to support the tire requiring tire pressure matching and bring it closer to the equipment frame, facilitating the lifting and replacement of the entire tire assembly. The translation slide and tire carrier work together to move tires of various models and materials closer to the tire mounting shaft, improving ease of use.

[0022] 2. When the tire assembly, supported by the sliding carriage and tire carrier, reaches the right side of the tire fixing axle and the wheel hub is fitted onto the tire fixing axle, the positioning pin passes through according to the number of wheel hub fixing holes and is connected to the corresponding fixing threaded hole through the positioning screw. This allows the wheel hub to be fixed according to different models of wheel hubs and the number of fixing holes. This enables the system matching and learning of the tire pressure monitoring equipment installed on the wheel hub when multiple models are produced on mixed production lines and the tire pressure monitoring equipment is affected by the military tire pressure monitoring equipment. The locking nut further secures the wheel hub and prevents it from falling off during rotation. The tire fixing axle is driven by the drive motor through the meshing of the driven gear and the transmission gear. This allows the tire pressure monitoring equipment to be matched and tested through the detection matching rod when the wheel hub rotates.

[0023] 3. When the wheel hub of the tire set is close to the right side wall of the equipment frame, the rotation of the bidirectional threaded rod is controlled by the cooperation of the twin-screw drive and the transmission wheel set. The distance between the two detection matching rods can be controlled by the bidirectional threaded rod, so that the tire pressure monitoring equipment can be matched and learned from the inner and outer sides of the wheel hub. This allows the TPMS produced on the mixed production line to be matched to the tire pressure monitoring equipment according to the different electromagnetic wave reflection and absorption capabilities of different wheel hub materials, which facilitates the improvement of the accuracy of the tire pressure monitoring equipment after it is installed in the vehicle.

[0043] By adopting the above technical solution, the drive shaft of the single screw drive 7 and the transmission wheel set 6 are used to control the one-way threaded rod 5 to rotate in both directions. This one-way threaded rod 5 controls the tire carrier 4 to lift and lower on the translation slide 3. The electric telescopic rod 2, which is set at the bottom of the right side wall of the equipment frame 1, connects to the translation slide 3.

The online tire pressure monitoring and matching device and its process also include: a counterweight block 1101 is fixedly connected to the left end of the tire fixing shaft 11 and rotatably connected to the equipment frame 1; a driven gear 1102 is provided on the left side wall of the tire fixing shaft 11 and meshes with the transmission gear 1001 on the rear side; ten fixing threaded holes 1103 are opened in a circular array in the right side wall of the tire fixing shaft 11, and the fixing threaded holes 1103 are connected to the positioning screw 1201 at the left end of the positioning column 12.

Thus, the tire carrier 4 is controlled to lift and lower on the translation slide 3 by the one-way screw rod 5.

[0054] 2) Then, the electric telescopic rod 2 and the translation slide 3 are connected to the bottom of the right side wall of the equipment frame 1. The electric telescopic rod 2 can control the translation slide 3 to slide left and right. With the cooperation of the sliding ball bearing 8 at the bottom of the translation slide 3, the translation slide 3 can slide smoothly.

Long strip-shaped TPMS matching probes are provided on the upper and lower side walls of the two detection matching rods (15).

10. The process of using an online tire pressure monitoring and matching device as described in claims 1-9 includes the following steps: 1). First, roll the tire assembly onto the translation slide (3). Then, control the one-way screw rod (5) to rotate in both directions through the cooperation of the drive shaft of the single screw drive (7) and the transmission wheel assembly (6). Thus, control the tire carrier (4) to lift and lower on the translation slide (3) through the one-way screw rod (5). 2). Then, by connecting the electric telescopic rod (2) set at the bottom of the right side wall of the equipment frame (1) with the translation slide (3), the translation slide (3) can be controlled to slide left and right by the electric telescopic rod (2). With the cooperation of the sliding ball (8) at the bottom of the translation slide (3), the translation slide (3) can slide smoothly, so that the tire that needs to be matched for tire pressure can be supported by the translation slide (3) and the tire bracket (4) to approach or the equipment frame (1) according to the usage requirements, so as to facilitate the lifting and replacement of the entire tire group. 3). Then, when the tire assembly lifted by the translation slide (3) and tire bracket (4) reaches the right side of the tire fixing shaft (11) and the wheel hub is put on the tire fixing shaft (11), the positioning pin (12) is passed through according to the number of wheel hub fixing holes and connected to the corresponding fixing thread hole (1103) through the positioning screw (1201). The wheel hub can be fixed according to different models of wheel hubs and the number of fixing holes. The wheel hub can be better fixed by locking the locking nut (13) to prevent the wheel hub from falling off when rotating. 4) Then the tire fixed shaft (11) is driven by the drive motor (10) through the meshing of the driven gear (1102) and the transmission gear (1001). At the same time, when the wheel hub of the tire group is close to the right side wall of the equipment frame (1), the double screw drive (9) and the transmission wheel group (6) are used to control the rotation of the double screw rod (14). The distance between the two detection matching rods (15) can be controlled by the double screw rod (14) so ​​that the tire pressure monitoring equipment can be matched and learned from the inner and outer sides of the wheel hub of the tire group. In this way, the TPMS produced by the mixed production line can be matched to the tire pressure monitoring equipment according to the different electromagnetic wave reflection and absorption capabilities of different wheel hub materials, which is conducive to improving the accuracy of the tire pressure monitoring equipment after it is installed on the vehicle.
