[0002] A servo drive wheel, an integrated mechanical structure integrating a driving motor, a speed reducer, and a steering motor, can realize functions of walking, traction, and steering. It is usually used in conjunction with a servo motor to improve the accuracy and response speed of use, and is mainly used in fields such as industrial automation, logistics transportation, and agricultural machinery.

[0003] It is found that the following problems have not been well solved: when the servo drive wheel is continuously used, mechanical wear will occur on its own, and various faults will occur in the equipment after long-term use. Therefore, the staff needs to disassemble the servo drive wheel or the driving wheel. However, when only the driving wheel is severely worn, the existing device needs to disassemble the entire device for replacement, which is time-consuming and laborious, inconvenient to selectively disassemble and replace according to the worn parts, and not convenient for the use of the device.

A semi-arc groove is opened on the outer wall of the bottom column, and the inner diameter of the semi-arc groove matches the outer diameter of the bump. The bottom end of the bottom column is fixedly connected to the top end of the rotating disk.

[0010] Preferably, the control member further includes an inner column, which is slidably connected in the inner wall of the fixed column. Connecting rods are fixedly connected to both ends of the inner column. The connecting rods penetrate through the fixed column and are slidably connected to the inner wall of the fixed column, and the outer walls of the connecting rods are fixedly connected to the bottom end of the switching disk;

[0011] An annular groove is opened in the inner wall of the inner column, and a number of annularly arranged extrusion balls are fitted in the inner wall of the annular groove. The front ends of the a number of extrusion balls are provided with ejection grooves, and the a number of ejection grooves are opened on the outer wall of the fixed column.

[0012] Preferably, the installation mechanism further includes a top plate, which is horizontally arranged at the top end of the switching disk. A connecting plate of a C-shaped mechanism is fixedly connected to the bottom end of the top plate, and the bottom end of the connecting plate is fixedly connected to the outer wall of the installation bin. A gear disk is fixedly connected to the top end of the connecting plate, and a transmission gear is engaged on the side wall of the gear disk. The top end of the transmission gear is connected to a servo motor, and the top end of the servo motor is fixedly connected to a top disk. The top end of the top disk is fixedly connected to the vehicle body through bolts.

[0013] Preferably, the installation mechanism further includes a rotating shaft, which is rotatably connected to the bottom end of the top plate through the shaft end. A plurality of clamping grooves are formed in the inner wall of the rotating shaft. A clamping column is inserted into the inner wall of the rotating shaft. A plurality of through grooves are formed in the outer wall of the clamping column at equal intervals. And a clamping plate is slidably connected to the inner wall of each of the plurality of through grooves. A left hinge rod is hinged in the inner wall of the clamping plate. And the other end of the left hinge rod is hinged to a movable column. A right hinge rod is hinged to the inner side of the left hinge rod. And one end of the right hinge rod is hinged to the outer wall of the clamping plate. And the other end of the right hinge rod is hinged to a limiting column. The bottom end of the limiting column is fixedly connected to the inner wall of the top plate;

[0014] The outer wall of the movable column is in spline connection with the inner wall of the limiting column. An upper rotation groove is formed in the outer wall of the movable column. The bottom end of the movable column is sleeved with a rotating sleeve. An inner rotation groove is formed in the inner wall of the bottom end of the rotating sleeve. And a push rod is inserted into the inner wall of the rotating sleeve. The bottom end of the push rod extends to the bottom end of the top plate;

[0015] Convex points are fixedly connected to the outer wall of the push rod. And convex points with the same structure are fixedly connected to the outer wall of the top end of the rotating sleeve.

[0016] A usage method of a robot servo wheel includes the following steps:

[0017] S1. During equipment installation, the staff can manually install the top plate on the bottom end of the vehicle body through bolts. Then, hold the protective shell and insert it towards the rotating shaft on the top plate. At this time, the clamping plate is pressed and contracts inward, so that the clamping column can be directly inserted into the inside of the rotating shaft. At this time, the clamping plate moves to the clamping groove, and the clamping plate resets through the spring and is inserted into the clamping groove, so that the whole protective shell is installed on the top plate;

[0018] S2. Then, the staff can manually align the shaft end of the driving wheel and insert it into the shaft end of the driving motor. Since the shaft ends of the driving motor and the driving wheel are in spline connection, one side of the driving wheel is installed on the protective shell. Then, the frustum block can be attached to the protective shell and the sealing cover can be pushed upward. At this time, the frustum block at the uppermost position respectively pushes open the front ends of the wedge block and the limiting rod through its own inclined surface, so that the uppermost frustum block is inserted into the installation groove. However, since the two frustum blocks are arranged oppositely, the lowermost frustum block cannot push open the limiting rod. So, the arrangement of a plurality of limiting rods at this time will make the lowermost frustum block unable to rise and be stuck between the two frustum blocks and unable to move. Thus, the sealing cover is restricted and installed on the protective shell;

[0019] S3. Next, when the staff needs to replace the driving wheel alone, they can manually pull the positioning post outwards. The positioning post is removed from the insertion slot. At this time, rotate the switching disk counterclockwise. The positioning post on the switching disk moves from the inclined slot towards the lower arc slot, and the switching disk moves downwards accordingly. As the switching disk moves downwards, the connecting rod at the lower end of the switching disk drives the inner column to move downwards first, and the annular groove on the bottom column moves synchronously. The groove wall of the annular groove no longer squeezes several extrusion balls to expand outwards, unlocking the inner column. At this time, as the switching disk continues to move downwards, the bottom end of the switching disk presses the pressure column. The sliding block in the pressure column slides inside the semi-circular arc groove of the bottom column, pushing the bottom column to rotate. The bottom column drives the rotating disk to rotate. The arc groove on the rotating disk pushes the limiting rod to move backwards through the convex block, and the limiting rod is pulled out from between the two frustum-shaped blocks;

[0020] S4. Immediately afterwards, without the restriction of the limiting rod, the staff manually pushes the sealing cover upwards again. The lower frustum-shaped block pushes the wedge-shaped block open. The wedge-shaped block enters the installation slot. At the same time, the wedge-shaped block is reset by the spring, pushing the lower frustum-shaped block and the upper frustum-shaped block together. At this time, when moving downwards, the two closed frustum-shaped blocks can squeeze the wedge-shaped block, continuously pass through the wedge-shaped block and move out of the installation slot. At this time, the sealing shell can be removed from the protective shell;

[0021] S5. When the staff needs to disassemble the protective shell, the staff pulls the positioning post outwards again and rotates the switching disk clockwise. The switching disk rotates from the inclined slot to the upper arc slot, and the switching disk moves upwards. The switching disk pushes the push rod, and the push rod rises. The push rod drives the rotating sleeve to rotate through the convex point. The rotating sleeve rotates. At this time, the convex point at the top of the rotating sleeve slides in the upper rotating slot, pushing the movable column to rise. The movable column pulls the left hinge rod to contract inwards. The left hinge rod drives the clamping plate to be received into the clamping column from the through slot, and the clamping plate is separated from the clamping groove, causing the upper half of the protective shell to be separated from the top plate. At this time, the protective shell can be pulled out to disassemble the protective shell.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] In the present invention, through the setting of the limiting rod and the two groups of frustum-shaped blocks, it is convenient for the staff to perform quick installation and disassembly.

[0024] In the present invention, through the setting of the switching disk, it is possible to control the up and down movement of the switching disk according to needs, select the required disassembly function, and facilitate the staff to perform disassembly and replacement according to needs.

[0025] In the present invention, through the setting of the clamping plate and the clamping groove, as well as the cooperative setting of the push rod and the switching disk, the staff can quickly disassemble the protective shell. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0043] 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 ordinary technical staff in the art without creative work belong to the scope of protection of the present invention.

[0044] Please refer to Figures 1 to 16 , the present invention provides a technical solution: a robot servo wheel, including a protective shell 1, a driving motor is fixedly connected to the outer wall of the protective shell 1, and a plug-in bin 2 is opened at the spindle end of the driving motor. A driving wheel 3 is inserted into the inner wall of the protective shell 1. The shaft end of the driving wheel 3 is inserted and arranged with the inner wall of the protective shell 1, and the shaft end of the driving wheel 3 is splined with the spindle of the driving motor. An installation mechanism 4 is arranged inside the protective shell 1;

[0045] The installation mechanism 4 includes an installation bin 41 which is opened in the inner wall of the protective shell 1. A guiding plate 42 is fixedly connected to the bottom wall of the installation bin 41. A number of guiding grooves 43 are equidistantly opened in the inner wall of the guiding plate 42. A limiting rod 44 is slidably connected inside a number of the guiding grooves 43. The front end of the limiting rod 44 is arranged in a spring telescopic structure. A number of bump blocks 45 are fixedly connected to the tops of the limiting rods 44. A fixing column 46 is fixedly connected to the top of the guiding plate 42. A rotating disk 47 is rotatably connected to the outer wall of the fixing column 46. A number of arc-shaped grooves 48 are annularly arranged at equal intervals at the bottom end of the rotating disk 47. A number of the arc-shaped grooves 48 and a number of the bump blocks 45 are arranged in one-to-one correspondence;

[0046] A control member 49 is arranged on the outer wall of the fixing column 46.

[0047] In this embodiment, as Figure 3 , Figure 4 , Figure 5 and Figure 9 shown, the installation mechanism 4 further includes an installation groove 410 which is opened in the inner wall of the protective shell 1. A wedge-shaped block 411 is slidably connected in the inner wall of the installation groove 410. A spring is fixedly connected to the rear end of the wedge-shaped block 411. The spring is fixedly connected to the inner wall of the protective shell 1. The front end of the wedge-shaped block 411 is in fit connection with a positioning column 412. Two relatively arranged frustum-shaped blocks 413 are sleeved on the outer wall of the positioning column 412. A sealing cover 414 is fixedly connected to the bottom end of the positioning column 412. The two frustum-shaped blocks 413 and the limiting rod 44 are horizontally arranged. Through the arrangement of the two frustum-shaped blocks 413, the frustum-shaped blocks 413 can be restricted during initial installation to achieve a quick installation effect.

[0048] In this embodiment, as Figure 9 shown, the front end of the limiting rod 44 has an inclined surface formed by machining. The outer diameter of the front end of the limiting rod 44 matches the distance between the two relatively arranged frustum-shaped blocks 413, so that only one of the two frustum-shaped blocks 413 can pass through. When the frustum-shaped block 413 passes through, it is inserted between the two frustum-shaped blocks 413 for locking.

[0049] In this embodiment, as Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the control member 49 includes an upper arc groove 491, the upper arc groove 491 is formed on the outer wall of the fixed column 46, both ends of the upper arc groove 491 communicate with an inclined groove 492, and the front end of the inclined groove 492 communicates with a lower arc groove 493. Insertion grooves 494 are formed at the centers of the two inclined grooves 492, and a positioning rod 495 is inserted into the inner wall of the insertion groove 494. A switching disk 496 is sleeved on the outer wall of the fixed column 46, the outer wall of the switching disk 496 is inserted and arranged with the positioning rod 495, and a return spring is sleeved on the outer wall of the positioning rod 495. The bottom end of the switching disk 496 is in close connection with a pressing column 497, a sliding block 498 is fixedly connected to the inner wall of the pressing column 497, and a bottom column 499 is inserted into the inner wall of the pressing column 497. A semi-arc groove 4910 is formed on the outer wall of the bottom column 499, and the inner diameter of the semi-arc groove 4910 matches the outer diameter of the bump 433. The bottom end of the bottom column 499 is fixedly connected to the top end of the rotating disk 47. Through the arrangement of the upper arc groove 491 and the lower arc groove 493, the switching disk 496 can be rotated to move the switching disk 496 up and down to control the position of the switching disk 496.

[0050] In this embodiment, as Figure 5 , Figure 6 , Figure 7 and Figure 8 shown, the control member 49 further includes an inner column 4911. The inner column 4911 is slidably connected to the inner wall of the fixed column 46, both ends of the inner column 4911 are fixedly connected with connecting rods 4912. The connecting rods 4912 penetrate through the fixed column 46, the connecting rods 4912 are slidably connected to the inner wall of the fixed column 46, and the outer wall of the connecting rods 4912 is fixedly connected to the bottom end of the switching disk 496;

[0051] An annular groove 4913 is formed in the inner wall of the inner column 4911, a number of extrusion balls 4914 arranged in an annular array are closely arranged on the inner wall of the annular groove 4913, and ejection grooves 4915 are arranged at the front ends of the number of extrusion balls 4914. The number of ejection grooves 4915 is formed on the outer wall of the fixed column 46. Through the arrangement of the number of extrusion balls 4914, the bottom column 499 can be locked to prevent the bottom column 499 from automatically rotating, resulting in installation failure.

[0052] In this embodiment, as Figure 10 , Figure 11 and Figure 12As shown, the installation mechanism 4 further includes a top plate 415. The top plate 415 is horizontally arranged at the top of the switching disc 496, and the bottom end of the top plate 415 is fixedly connected to the connecting plate 416 of the C-shaped mechanism. Moreover, the bottom end of the connecting plate 416 is fixedly connected to the outer wall of the installation bin 41. The top end of the connecting plate 416 is fixedly connected to a gear disc 417, and a transmission gear 418 is engaged with the side wall of the gear disc 417. The top end of the transmission gear 418 is connected to a servo motor, and the top end of the servo motor is fixedly connected to a top disc 419. The top end of the top disc 419 is fixedly connected to the vehicle body through bolts. When the equipment is in use, the top disc 419 needs to be fixed on the vehicle body to facilitate quick installation and disassembly, and it is convenient for the staff to carry out maintenance and replacement.

[0053] In this embodiment, as Figure 14 , Figure 14 , Figure 15 and Figure 16 shown, the installation mechanism 4 further includes a rotating shaft 420. The rotating shaft 420 is rotatably connected to the bottom end of the top disc 419 through the shaft end. A plurality of clamping grooves 421 are formed in the inner wall of the rotating shaft 420. A clamping column 422 is inserted into the inner wall of the rotating shaft 420. A plurality of equally spaced through grooves 423 are formed in the outer wall of the clamping column 422, and a clamping plate 424 is slidably connected to the inner walls of the plurality of through grooves 423. A left hinge rod 425 is hinged to the inner wall of the clamping plate 424, and the other end of the left hinge rod 425 is hinged to a movable column 426. A right hinge rod 427 is hinged to the inner side of the left hinge rod 425, and one end of the right hinge rod 427 is hinged to the outer wall of the clamping plate 424, and the other end of the right hinge rod 427 is hinged to a limiting column 428. The bottom end of the limiting column 428 is fixedly connected to the inner wall of the top plate 415;

[0054] The outer wall of the movable column 426 is in spline connection with the inner wall of the limiting column 428. An upper rotation groove 429 is formed in the outer wall of the movable column 426. The bottom end of the movable column 426 is sleeved with a rotating sleeve 430. An inner rotation groove 431 is formed in the inner wall of the bottom end of the rotating sleeve 430. A push rod 432 is inserted into the inner wall of the rotating sleeve 430. The bottom end of the push rod 432 extends to the bottom end of the top plate 415;

[0055] Convex points 433 are fixedly connected to the outer wall of the push rod 432, and convex points 433 with the same structure are fixedly connected to the outer wall of the top end of the rotating sleeve 430. Through the arrangement of the clamping plate 424, when the switching disc 496 rises, the clamping plate 424 is triggered to contract and separate from the clamping groove 421, and the protective shell 1 can be directly pulled out for quick disassembly.

[0056] In this embodiment, as Figures 1 to 16 shown, a method for using a robot servo wheel includes the following steps:

[0057] S1. During equipment installation, the staff can manually install the top plate 419 at the bottom end of the vehicle body through bolts. Then, hold the protective shell 1 and insert it towards the rotating shaft 420 on the top plate 419. At this time, the clamping plate 424 is pressed and contracts inward, enabling the clamping column 422 to directly insert into the inside of the rotating shaft 420. At this time, the clamping plate 424 moves to the clamping groove 421, and the clamping plate 424 is reset by the spring and inserted into the clamping groove 421, so that the entire protective shell 1 is installed on the top plate 419;

[0058] S2. Then, the staff can manually align the shaft end of the driving wheel 3 and insert it into the shaft end of the driving motor. Since the shaft ends of the driving motor and the driving wheel 3 are connected by splines, one side of the driving wheel 3 is installed on the protective shell 1. Then, the frustum block 413 can be attached to the protective shell 1, and the sealing cover 414 is pushed upward. At this time, the uppermost frustum block 413 respectively pushes open the front ends of the wedge block 411 and the limiting rod 44 through its own inclined surface, so that the uppermost frustum block 413 is inserted into the installation groove 410. However, since the two frustum blocks 413 are arranged oppositely, the lowermost frustum block 413 cannot push open the limiting rod 44. The setting of several limiting rods 44 at this time will cause the lowermost frustum block 413 to be unable to rise and be stuck between the two frustum blocks 413 and unable to move, thereby restricting the sealing cover 414 and installing it on the protective shell 1;

[0059] S3. Then, when the staff needs to replace the driving wheel 3 alone, the positioning column 412 can be manually pulled outwards. The positioning column 412 is removed from the insertion groove 494. At this time, the switching disk 496 is rotated counterclockwise. The positioning column 412 on the switching disk 496 moves from the inclined groove 492 towards the lower arc groove 493. The switching disk 496 moves downwards accordingly. As the switching disk 496 moves downwards, the connecting rod 4912 at the lower end of the switching disk 496 drives the inner column 4911 to move downwards first, and the annular groove 4913 on the bottom column 499 moves synchronously. The groove wall of the annular groove 4913 no longer squeezes several extrusion balls 4914 to expand outwards, unlocking the inner column 4911. At this time, as the switching disk 496 continues to move downwards, the bottom end of the switching disk 496 presses the pressure column 497. The sliding block 498 in the pressure column 497 slides inside the semi-circular arc groove 4910 of the bottom column 499, pushing the bottom column 499 to rotate. The bottom column 499 drives the rotating disk 47 to rotate. The arc groove 48 on the rotating disk 47 pushes the limiting rod 44 to move backwards through the convex block 45, and the limiting rod 44 is withdrawn from between the two frustum blocks 413;

[0060] S4. Immediately afterwards, without the restriction of the limiting rod 44, the staff manually pushes the sealing cover 414 upwards again. The frustum block 413 at the lower end pushes the wedge-shaped block 411 open, and the wedge-shaped block 411 enters the installation groove 410. At the same time, the wedge-shaped block 411 is reset by the spring, pushing the frustum block 413 at the lower end and the frustum block 413 at the upper end to close. Then, when moving downwards, the two closed frustum blocks 413 can squeeze the wedge-shaped block 411, continuously pass through the wedge-shaped block 411 and move out of the installation groove 410. At this time, the sealing shell can be removed from the protective shell 1;

[0061] S5. When the staff needs to disassemble the protective shell 1, the staff pulls the positioning column 412 outwards again and rotates the switching disk 496 clockwise. The switching disk 496 rotates from the inclined groove 492 to the upper arc groove 491. The switching disk 496 moves upwards, and the switching disk 496 pushes the push rod 432. The push rod 432 rises and drives the rotating sleeve 430 to rotate through the bump 433. The rotating sleeve 430 rotates. At this time, the bump 433 at the top of the rotating sleeve 430 slides in the upper rotating groove 429, pushing the movable column 426 upwards. The movable column 426 pulls the left hinge rod 425 to contract inwards.

8. A method for using a robot servo steering wheel, using the robot servo steering wheel according to any one of claims 1 to 7, characterized in that: The steps include: S1. When installing the equipment, the staff can manually install the top plate (419) on the bottom end of the vehicle body by bolts, and then hold the protective shell (1) and insert it toward the rotating shaft (420) on the top plate (419). At this time, the clamping plate (424) is compressed and shrinks inward, so that the clamping column (422) can be directly inserted into the rotating shaft (420). At this time, the clamping plate (424) moves to the clamping groove (421), and the clamping plate (424) is reset by the spring and inserted into the clamping groove (421), so that the protective shell (1) is installed on the top plate (419) as a whole; S2. The staff can then manually align the shaft end of the driving wheel (3) with the shaft end of the driving motor and insert it. Since the shaft ends of the driving motor and the driving wheel (3) are splined, one side of the driving wheel (3) is installed on the protective shell (1). Then, the truncated cone block (413) can be fitted on the protective shell (1) and the sealing cover (414) can be pushed upward. At this time, the truncated cone block (413) at the top can respectively move the front ends of the wedge block (411) and the limit rod (44) through its own inclined surface. The uppermost truncated cone block (413) is pushed open so that the uppermost truncated cone block (413) is inserted into the installation groove (410). However, since the two truncated cone blocks (413) are arranged relative to each other, the lowermost truncated cone block (413) cannot push open the limiting rod (44). Therefore, the arrangement of the plurality of limiting rods (44) at this time will make the lower truncated cone block (413) unable to rise and get stuck between the two truncated cone blocks (413) and unable to move, thereby restricting the sealing cover (414) and installing it on the protective shell (1); S3. When the staff needs to replace the driving wheel (3) alone, the positioning column (412) can be manually pulled outward, and the positioning column (412) is removed from the insertion groove (494). At this time, the switching disk (496) is rotated counterclockwise, and the positioning column (412) on the switching disk (496) moves from the inclined groove (492) to the lower arc groove (493), and the switching disk (496) moves downward accordingly. The switching disk (496) moves downward, and the connecting rod (4912) at the lower end of the switching disk (496) drives the inner column (4911) to move downward first, and the annular groove (4913) on the bottom column (499) moves synchronously, and the annular groove (4913) on the bottom column (499) moves synchronously. 3) The groove wall no longer squeezes a plurality of squeezing balls (4914) outwardly, unlocking the inner column (4911), and at this time the switching disk (496) continues to move downward, the bottom end of the switching disk (496) presses the column (497), and the sliding block (498) in the column (497) slides inside the semi-arc groove (4910) of the bottom column (499), pushing the bottom column (499) to rotate, and the bottom column (499) drives the rotating disk (47) to rotate, and the arc groove (48) on the rotating disk (47) pushes the limit rod (44) to move backward through the protrusion (45), and the limit rod (44) is pulled out from between the two truncated cone blocks (413); S4. Then, without the restriction of the limit rod (44), the staff manually pushes up the sealing cover (414) again, and the truncated cone block (413) at the lower end pushes the wedge block (411) open, and the wedge block (411) enters the installation groove (410). At the same time, the wedge block (411) is reset by the spring, pushing the truncated cone block (413) at the lower end and the truncated cone block (413) at the upper end to close together, and then moves downward. The two closed truncated cone blocks (413) can squeeze the wedge block (411), continuously pass through the wedge block (411) and move out of the installation groove (410), and then the sealing shell can be removed from the protective shell (1); S5. When the staff needs to remove the protective shell (1), the staff pulls the positioning column (412) outward again, rotates the switching disk (496) clockwise, and the switching disk (496) rotates from the inclined groove (492) to the upper arc groove (491). The switching disk (496) moves upward, and the switching disk (496) pushes the push rod (432). The push rod (432) rises and pushes the rotating sleeve (430) to rotate through the protrusion (433). The rotating sleeve (430) rotates. At this time, the rotating sleeve (430) ) The protrusion (433) at the top of the protective shell (1) slides in the upper rotation groove (429), pushing the movable column (426) to rise, and the movable column (426) pulls the left hinge rod (425) to retract inward, and the left hinge rod (425) drives the clamping plate (424) to be received into the clamping column (422) from the through groove (423), and the clamping plate (424) is separated from the clamping groove (421), so that the upper part of the protective shell (1) is separated from the top plate (419), and the protective shell (1) can be pulled out and disassembled.
