Description

Technical Field

[0001] The present invention relates to the technical field of luggage rollers, and specifically relates to a luggage roller and a roller bearing with a shock absorption effect. Background Art

[0002] A luggage roller is a common device, mainly used on transportation tools such as suitcases and trolleys to provide frictional force so that these tools can roll forward. The main function of the roller is to reduce friction and make it more labor-saving when dragging an object on the ground.

[0003] Currently, the luggage roller is directly connected to the luggage wheel frame through a bearing and a round shaft. It is okay when traveling on a smooth road surface, but on a relatively potholed paved road surface, such as a brick road or an asphalt road surface, etc., when the roller travels, due to the small contact area of the roller with the ground, even a slightly potholed road surface will cause vibrations. The above-mentioned road surfaces are the most severe. Such vibrations cause greater damage to the roller and are prone to cause roller damage, especially when there are more and heavier items in the luggage, the damage is greater, resulting in time-consuming and laborious pulling.

Detailed implementation manners

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-10, the present invention provides a technical solution: including a wheel frame 1, an internal bearing 2 and a wheel set 4. The internal bearing 2 is connected and arranged inside the wheel frame 1. As can be seen from the drawings, a round shaft is connected and arranged inside the internal bearing 2. The wheel set 4 is connected and arranged at both ends of the round shaft. The internal bearing 2 includes an inner steel ring 5 and an outer steel ring 6. On both sides of the surface of the inner steel ring 5, a lining frame 7 is connected and arranged. Inside the lining frame 7, multiple support shafts 8 are rotatably arranged. Grooves are formed on the outer surface of the inner steel ring 5, and multiple piezoelectric ceramics 9 are connected in the grooves. On the inner ring of the outer steel ring 6, multiple elastic pieces 11 are connected and arranged. On one side of each elastic piece 11, a roller 12 is rotatably arranged. On both sides of the outer steel ring 6 and the inner steel ring 5, side seals 15 are connected and arranged. On the inner ring of the inner steel ring 5, a primary buffer mechanism is connected and arranged; The wheel set 4 includes an inner hub 20 and a wheel sleeve 28. On the surface of the inner hub 20, an installation kit 21 is connected and arranged. On the surface of the installation kit 21, multiple shock-absorbing rubber frames 22 are connected and arranged. The other ends of the shock-absorbing rubber frames 22 are connected and arranged with an outer hub 23. On one side of the inner hub 20, a fitting groove is formed, and a control energy mechanism 24 is connected and arranged in the fitting groove. On one side of the inner hub 20, a hub cap 25 is fitted and connected. The hub cap 25 is also made of rubber. On the side of the inner hub 20 away from the hub cap 25, a buffer mechanism 26 is connected and arranged. On the outer ring of the outer hub 23, multiple driven wheel rollers 27 are rotatably arranged. The wheel sleeve 28 is sleeved and connected on the surface of the driven wheel rollers 27. On one side of the inner wall of the wheel sleeve 28, a power receiving driving mechanism 29 is connected and arranged. On the surface of the installation kit 21, two sets of micro electric push rods 30 are connected and arranged. The output ends of the micro electric push rods 30 are connected and arranged with an extension extrusion mechanism 31. On one side of the extension extrusion mechanism 31, an extension frame 32 is connected and arranged. On one side of the installation kit 21, a fixed sleeve 33 is connected and arranged. The extension frame 32 is slidably connected with the fixed sleeve 33.

[0020] Refer to Figure 3 As shown, on both sides of the lining frame 7 at the positions where the mutually approaching sides of the outer steel ring 6 and the inner steel ring 5 are located, an inner sealing ring 10 is connected and arranged. Through Figure 3 the enlarged part in, it can be seen that the setting of the inner sealing ring 10 can block the lining frame 7 inside the outer steel ring 6 and the inner steel ring 5, thereby blocking the piezoelectric ceramics 9, the elastic pieces 11 and the rollers 12 located inside, and preventing lubricating oil from seeping in as much as possible, so as to ensure the power generation effect.

[0021] Refer to Figure 3 and Figure 5As shown, on one side of the inner steel ring 5, a power connection piece 13 and an external power connection piece 14 are connected and arranged. On one side of the external power connection piece 14 close to the power connection piece 13, two contact pieces 141 are connected and arranged. One side of the contact piece 141 is in contact with the power connection piece 13. Among them, the external power connection piece 14 is connected and arranged on one side of the circular shaft. The power connection piece 13 is electrically connected to each piezoelectric ceramic 9. When the piezoelectric ceramic 9 generates current due to friction, the current will be transmitted to the power connection piece 13 and then transmitted to the external power connection piece 14 through the contact of the contact piece 141. An insulating coating is connected and arranged on the inner ring of the external power connection piece 14 to prevent the current from being transmitted to the circular shaft. The external power connection piece 14 is electrically connected to the energy control mechanism 24.

[0022] Refer to Figure 5 As shown, the primary buffer mechanism includes a connecting frame 16, a buffer rubber sleeve 19 and a fixed sleeve frame 17 connected and arranged on the inner ring of the inner steel ring 5. Positioning strips 18 are connected and arranged on one side of the fixed sleeve frame 17 and the connecting frame 16 close to each other. One end of the positioning strips 18 close to each other is connected and arranged to the buffer rubber sleeve 19. The fixed sleeve frame 17 is connected to the circular shaft. When vibration occurs, it will be transmitted to the buffer rubber sleeve 19 through the fixed sleeve frame 17, playing a shock-absorbing effect on the connecting frame 16, thereby ensuring the shock-absorbing effect on the internal bearing 2.

[0023] Refer to Figure 9 As shown, the energy control mechanism 24 includes an installation ring 241 and an installation circuit board frame 242 connected and arranged inside the fitting groove. On one side of the inner wall of the installation ring 241, a fixed magnet ring 243 is connected and arranged. On the inner side of the installation ring 241, a pushing magnet ring 244 is connected and arranged. Auxiliary magnet rings 245 are connected and arranged on both the inner and outer sides of the installation circuit board frame 242, and an adsorption magnet 246 is connected and arranged on one side close to the fixed magnet ring 243. A power supply processing unit is connected and arranged on one side of the installation circuit board frame 242. Through the adsorption between the adsorption magnet 246 and the fixed magnet ring 243, the installation circuit board frame 242 is connected to the installation ring 241. At the same time, the diameter of the adsorption magnet 246 is smaller than that of the fixed magnet ring 243, so that a certain moving space is left for the installation circuit board frame 242 on one side of the installation ring 241. At the same time, the sides of the auxiliary magnet ring 245 and the pushing magnet ring 244 close to each other are of the same pole, so as to provide a repulsive force for the installation circuit board frame 242 to prevent direct collision and provide a protection effect for the power supply processing unit; The power processing unit includes a DC conversion chip 247, a capacitor 248, a control chip 249, a voltage regulator chip 250 and a vibration sensor chip 251 connected to one side of the mounting circuit board frame 242. A heat dissipation hole is opened on one side of the hub cover 25 corresponding to the power processing unit. The electric heat treatment unit is electrically connected to the buffer mechanism 26, the extension and extrusion mechanism 31 and the micro electric push rod 30. The external electric chip 14 transmits the current to the DC conversion chip 247, converts it into AC, and then stabilizes the voltage through the voltage regulator chip 250. The capacitor 248 can play the role of energy storage and filtering to ensure the stability of the overall circuit. At the same time, the vibration sensor chip 251 detects the vibration state of the wheel group 4 in the moving state, thereby sending a corresponding control signal through the control chip 249. When in use, a threshold is set for the monitoring of the vibration sensor chip 251, which is used as a trigger condition.

[0024] Reference Figure 10 As shown, the buffer mechanism 26 includes an annular frame 261 connected to one side of the inner hub 20, a plurality of cylinder bodies 262 are connected to the surface of the annular frame 261, a connecting rod 263 is slidably provided at one end of the cylinder body 262, a piston block 264 is connected to one end of the connecting rod 263, a traction spring 265 is connected to one side of the piston block 264, the other end of the traction spring 265 is connected to one side of the inner wall of the annular frame 261, an extension rod 266 is connected to the other end of the connecting rod 263, a limiting ball head 267 is connected to the other end of the extension rod 266, a magnetic fluid 268 is filled in the annular frame 261, a plurality of through holes are provided on one side of the piston block 264, a limiting arc groove 111 is provided on the inner side of the outer hub 23 corresponding to the extension rod 266, When in use, the annular frame 261 is fixed on the inner hub 20. When the vibration is transmitted to the annular frame 261 through the inner hub 20, it will cause the piston block 264 to slide in the cylinder body 262. The setting of the traction spring 265 provides a certain traction force. At the same time, the through hole on one side of the piston block 264 slows down the passage speed of the magnetic fluid 268, thereby achieving a buffering effect. When the piston block 264 slides, since the limiting ball head 267 slides in the limiting arc groove 111 and will not be separated from the limiting arc groove 111, a supporting effect is achieved through the connection between the connecting rod 263 and the extension rod 266. When a large and frequent vibration amplitude is detected, the magnetic fluid 268 is energized through the power processing unit to increase its viscosity and increase the buffering and shock absorption effect.

[0025] Reference Figure 4 and Figure 6As shown, a friction layer 281 is provided on one side of the inner wall of the wheel sleeve 28 corresponding to the driven wheel roller 27, and an anti-bias layer 282 is provided on the corresponding outer wheel hub 23. By setting the anti-bias layer 282, the wheel sleeve 28 will be stably embedded in the inner side of the outer wheel hub 23. When the wheel sleeve 28 rolls, the friction layer 281 can ensure the friction with the driven wheel roller 27, while maintaining the support, reducing the friction between the driven wheel roller 27 and the wheel sleeve 28. The outer surface of the wheel sleeve 28 is provided with wheel grooves. Because it is a conventional setting, it is not repeated in the specification and is not drawn in the drawings.

[0026] Reference Figure 6 As shown, the power-receiving drive mechanism 29 includes a ceramic plate frame 291 and a ceramic plate frame 1 292 which are rotatably arranged between the inner sides of the wheel sleeve 28. The sides of the ceramic plate frame 291 and the ceramic plate frame 292 which are close to each other are rotatably connected, and a permanent magnet 293 is connected to one side. As shown in the accompanying drawings, the ceramic plate frame 1 291 and the ceramic plate frame 292 are folded in an untriggered state. When the extending and extruding mechanism 31 is pushed out by the micro electric push rod 30, the ceramic plate frame 1 291 and the ceramic plate frame 292 can be stretched open, so that the power-receiving drive mechanism 29 can fit with the stretched wheel sleeve 28 to ensure the active travel effect.

[0027] Reference Figure 7 As shown, the extending and extruding mechanism 31 includes an arc frame 311, and multiple groups of guide rollers 312 are rotatably arranged on both sides of the arc frame 311. Multiple groups of core frames 313 are connected to the inner side of the arc frame 311, and winding coils 314 are connected to one side of the core frames 313. One side of the arc frame 311 is connected to a mounting seat block 222 and one side of the mounting kit 21 is connected to the other side. The micro electric push rod 30, the extending frame 32 and the fixing sleeve 33 are connected and arranged between the mounting seat block 222. The micro electric push rod 30 extends and pushes the arc frame 311 , so that the arc frame 311 moves out of the outer hub 23, thereby squeezing the wheel sleeve 28 through the guide roller 312, and the arc frames 311 extending on both sides cooperate with the outer hub 23, so that the wheel sleeve 28 forms a triangle. After the wheel sleeve 28 is stretched, the power receiving drive mechanism 29 is also stretched, and the winding coil 314 is energized through the power processing unit to generate a magnetic field, thereby pushing the permanent magnet 293. Through the setting of the driven roller 27 and the guide roller 312, the wheel sleeve 28 can be actively operated, thereby automatically moving forward.

[0028] The implementation principle of this application is as follows: When the invention is in use and the luggage is pulled forward on a relatively flat road surface, such as a flat and smooth road surface at an airport or on a floor, the vibration is small, and multiple permanent magnets 293 will generate an adsorption force with the outer wheel hub 23, thereby preventing rolling between the wheel sleeve 28 and the outer wheel hub 23. Through the setting of 8 between the inner steel ring 5 and the outer steel ring 6, the smoothness of the movement is ensured, and the wheel set 4 rolls to form a rolling motion. When the inner steel ring 5 rotates with the wheel set 4 through the connection of the round shaft, the rollers 12 on the inner side of the elastic sheet 11 will rub and squeeze each piezoelectric ceramic 9, thereby generating an electric current, and the electric current is transmitted to the power processing unit through the connection of the power receiving sheet 13 and the external power receiving sheet 14. When the luggage travels on a relatively bumpy road surface, such as an uneven paved road surface like bricks or asphalt, when the vibration sensor chip 251 detects a large vibration, the power processing unit sends an electric current to the buffer mechanism 26 to increase the damping effect, thereby enhancing the shock absorption effect. At the same time, the micro electric push rod 30 extends to push the extension and extrusion mechanism 31 to move outward, expanding the wheel sleeve 28 into a triangle, thereby increasing the contact area with the ground. At the same time, the winding coil 314 is energized to generate a magnetic field, which reacts with the permanent magnet 293 to push the wheel sleeve 28 to move forward actively, greatly reducing the human effort when carrying heavy items.
