DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] like Figures 1 to 7As shown, a solid tire slip detection device 100 includes: a power device 10, a first force-applying component 20 for synchronously moving with the wheel hub 102, and a second force-applying component 30 for synchronously moving with the solid tire 101.

[0031] The first force-applying assembly 20 includes a sleeve 21, a base 22, a screw shaft 23, a hand-cranked wheel 24, and two first sliding assemblies 25. The sleeve 21 is fixed to the base 22. A vent is provided in the middle of the sleeve 21. The hand-cranked wheel 24 is rotated by the user to drive the screw shaft 23. The hand-cranked wheel can be directly mounted on the screw shaft to directly drive the screw shaft to rotate. The hand-cranked wheel can also indirectly drive the screw shaft to rotate. Specifically, the hand-cranked wheel 24 indirectly drives the screw shaft 23 to rotate via a transmission mechanism. The transmission mechanism can be a gear transmission mechanism, a worm gear transmission mechanism, or a belt transmission mechanism. Specifically, the transmission mechanism is a gear transmission mechanism. The transmission mechanism includes a driving bevel gear 241 and a passive bevel gear 232. The driving bevel gear 241 is fixed to the axle of the hand-cranked wheel 24. The passive bevel gear 232 is mounted on the screw shaft 23. The driving bevel gear 241 meshes with the passive bevel gear 232. The screw shaft 23 is rotatably mounted to the base 22. Screw structures 231 with opposite thread rotation directions are formed at both ends of the screw shaft 23. Two first sliding assemblies 25 are respectively disposed at both ends of the screw shaft 23. The first sliding assembly 25 includes a slide rod 251, a screw nut 252, a first slide seat 253, and a first drive member 254 for inserting into the hole in the hub 102. The slide rod 251 is inserted into the sleeve 21 from the end and slides along the sleeve 21. The air vent provided in the middle of the sleeve 21 allows for communication between the interior and exterior of the sleeve 21, thereby balancing air pressure and preventing movement of the slide rod 251 within the sleeve 21 in the presence of compressed air. The screw nut 252 and the screw structure 231 constitute a screw nut transmission mechanism. The screw nut 252 and the slide rod 251 are fixed to the first slide seat 253. The first drive member 254 is mounted to the first slide seat 253.

[0032] The relative positions of the two first slides 253 can be adjusted by rotating the hand wheel 24, thereby adjusting the relative positions of the two first driving members 254 to adapt to different wheel hubs.

[0033] The second force-applying assembly 30 includes a rotating sleeve 31, a guide rod 32, and two second sliding assemblies 33. The rotating sleeve 31 is rotatably mounted to the base 22. The guide rod 32 is fixed to the rotating sleeve 31. The two second sliding assemblies 33 are respectively disposed at each end of the guide rod 32. The second sliding assembly 33 includes a second slide 331, a second driving member 332 for inserting into the tread groove of the solid tire 101, and a locking assembly 333 for locking the position of the second slide 331 relative to the guide rod 32. The second slide 331 is slidably mounted to the guide rod 32. The second driving member 332 is mounted to the second slide 331. The locking assembly 333 includes a locking bolt 3331, a locking nut 3332, and a lower clamping plate 3333. The top of the lower clamping plate 3333 contacts the guide rod 32. The locking bolt 3331 passes through the second slide 331 and the lower clamping plate 3333 and is threadedly connected to the locking nut 3332.

[0034] When the locking assembly 333 is unlocked, the positions of the two second slides 331 can be adjusted, thereby adjusting the positions of the two second driving members 332 to adapt to different solid tires.

[0035] The first driving member 254 and the second driving member 332 can be designed in structure and shape according to the structure of the solid tire and the structure of the wheel hub. For example, the second driving member 332 can be designed in a contoured manner according to the tread of the solid tire so that the solid tire can be embedded in the second driving member 332.

[0036] The power unit 10 includes a motor 11, a torque sensor 12, a gear 13, and an internal gear ring 14. The internal gear ring 14 is fixed to the top of a rotating sleeve 31. The torque sensor 12 is connected at both ends to the motor shaft of the motor 11 and the gear 13, respectively. The gear 13 meshes with the internal gear ring 14, which is fixed to the rotating sleeve 31. The motor 11 is fixed to and disposed within the base 22.

[0037] Torque sensor 12 detects torque. If relative rotation between the solid tire 101 and the wheel hub 102 does not occur when the predetermined torque is reached, the tire is considered qualified and no slipping occurs. As torque increases, if relative rotation between the solid tire 101 and the wheel hub 102 does occur before the predetermined torque is reached, the tire is considered unqualified and slipping occurs. Motor 11 is controlled by gradually increasing output torque.

[0038] In a specific embodiment, there are two guide rods 32. The second force-applying assembly 30 further includes two guide rod fixing plates 34. The two guide rod fixing plates 34 are respectively fixed to the ends of the rotating sleeve 31. The two guide rods 32 simultaneously pass through the two guide rod fixing plates 34 and are fixed to the two guide rod fixing plates 34.

[0039] As a specific embodiment, two notches for the guide rods 32 to be embedded in are formed on both sides of the rotating sleeve 31. The two guide rods 32 are respectively embedded in the two notches.

[0040] As a specific implementation, the second slide 331 and the guide rod 32 are slidably connected via a linear bearing.

[0041] As a specific embodiment, the sliding direction of the second sliding seat 331 along the guide rod 32 and the sliding direction of the sliding rod 251 along the sliding sleeve 21 are both perpendicular to the rotation axis of the rotating sleeve 31 relative to the base 22 .

[0042] As a specific embodiment, the bottom of the inner gear ring 14 is fixed to the top of the rotating sleeve 31. A cover 141 is fixed to the top of the inner gear ring 14. The cover 141 closes the top of the inner gear ring 14 to prevent foreign matter from entering the inner gear ring 14.

[0043] As a specific embodiment, the first driving member 254 is detachably mounted to the first slide 253. The second driving member 332 is detachably mounted to the second slide 331. Different first driving members and second driving members can be selected according to different solid tires and wheel hubs.

[0044] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0045] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
