[0045] As shown in Figure 1 , Figure 2 , Figures 8 to 13 , the educational robot of the embodiment of the present application adopts a wheeled walking system. Preferably, the wheeled walking system comprises four wheel group structures 10, as shown in Figure 1 and Figure 8 , the structural forms of the four wheel group structures 10 are the same, and each wheel group structure 10 has independent adjustment function, wherein the adjustment function includes lifting function of lifting or lowering the overall height of the intelligent vehicle and speed regulation function of independently adjusting the rotating speed of the wheel 11.

[0046] As shown in Figure 1 and Figure 2 , each wheel group structure 10 comprises a wheel 11, a connecting arm 12 and two driving members 13. The connecting arm 12 is a supporting installation carrier of the wheel group structure 10, one of the driving members 13 is installed at the first end of the connecting arm 12, and the other driving member 13 and the wheel 11 are detachably assembled to form a driving wheel module.

[0047] As shown in Figures 2 to 4As shown, the connecting arm 12 includes a first outer support housing 121, a second outer support housing 122, and a rotating inner support housing 123.

[0048] like Figure 4 As shown, the first outer support housing 121 includes a first sleeve 1211 and a first frame 1212. The two ends of the first frame 1212 are connected to the first sleeve 1211, forming a racetrack-shaped first outer support housing 121. The first sleeve 1211 is located at the first end of the first outer support housing 121, and the first frame 1212 forms the second end of the first outer support housing 121 opposite to the first sleeve 1211. Figure 2 and Figure 4 As shown, the first sleeve 1211 has multiple notches 1213 that are circumferentially spaced around the central axis of the first sleeve 1211, and, as Figure 3 and Figure 4 As shown, a first mounting through hole 1214 is provided on the first frame edge 1212, which is the second end of the first outer bracket housing 121.

[0049] like Figure 4 As shown, the second outer support housing 122 includes a cap portion 1221 corresponding to the first sleeve 1211 and a second frame edge 1222. The two ends of the second frame edge 1222 are connected to the cap portion 1221, forming a racetrack-shaped second outer support housing 122 that matches the racetrack shape of the first outer support housing 121. The cap portion 1221 is provided with hooks 1223 corresponding to a plurality of latches 1213. The cap portion 1221 fits snugly onto the first sleeve 1211, and each hook 1223 engages in its corresponding latch 1213. Specifically, the cap portion 1221 is provided with a stop protrusion 1224, and the end of the first sleeve 1211 facing the cap portion 1221 is provided with a plurality of notches 1215 spaced apart, such as... Figure 2 and Figure 4 As shown, after the cap portion 1221 is fitted onto the first sleeve 1211, the notch 1215 and the cap portion 1221 form a sliding guide groove. Specifically, the first sleeve 1211 has two symmetrical notches 1215 on its end. When the cap portion 1221 is fitted onto the first sleeve 1211, the second frame edge 1222 simultaneously mates with the first frame edge 1212 and is fixed together with screws. Figure 3 As shown, after the first frame edge 1212 and the second frame edge 1222 are joined together, two opposing first clearance openings 1231 and second clearance openings 1232 are formed, and the first mounting through hole 1214 is located on the second frame edge 1222 between the first clearance opening 1231 and the second clearance opening 1232.

[0050] like Figure 4As shown, the rotating inner support shell 123 comprises a second sleeve 1233 and a third frame edge 1234, two ends of the third frame edge 1234 are connected to the second sleeve 1233 to form a race track type rotating inner support shell 123. The second sleeve 1233 is located at the first end of the rotating inner support shell 123, and the third frame edge 1234 forms the second end of the rotating inner support shell 123 opposite to the second sleeve 1233. The second sleeve 1233 is rotatably sleeved on the first sleeve 1211, and the inner wall of the second sleeve 1233 is provided with a plurality of clamping protrusions 1235, each clamping protrusion 1235 is correspondingly located in the notch 1215, and the corresponding second sleeve 1233 is provided with two opposite clamping protrusions 1235. Then the second outer support shell 122 is coveringly connected to the first outer support shell 121, at this time the second sleeve 1233 is blocked by the sleeve cover part 1221 and cannot be separated from the first sleeve 1211, and the clamping protrusions 1235 and the stop protrusions 1224 are spaced apart. After the second outer support shell 122 is coveringly connected to the first outer support shell 121, the third frame edge 1234 can pass through the first avoiding port 1231 and the second avoiding port 1232 during the rotation of the rotating inner support shell 123 around the central axis of the first sleeve 1211, when the third frame edge 1234 is located at the space position between the first avoiding port 1231 and the second avoiding port 1232, the clamping protrusions 1235 are located at the middle position of the notch 1215, that is, at this time the third frame edge 1234 can be rotated towards the first avoiding port 1231 and pass through the first avoiding port 1231, and also can be rotated towards the second avoiding port 1232 and pass through the second avoiding port 1232. The second mounting through hole 1236 is formed in the third frame edge 1234 as the second end of the rotating inner support shell 123, when the third frame edge 1234 is located at the space position between the first avoiding port 1231 and the second avoiding port 1232, at this time the second mounting through hole 1236 and the first mounting through hole 1214 are opposite to each other and have a spacing therebetween. And the third frame edge 1234 as the second end of the rotating inner support shell 123 forms a recessed groove 1237 towards the outer side wall of the first mounting through hole 1214, the extension direction of the recessed groove 1237 is consistent with the extension direction of the third frame edge 1234.

[0051] As Figure 5 And Figure 6As shown, the driving member 13 comprises a first housing 131, a second housing 132, an output end housing 133 and internal components (not shown, the internal components generally comprise a circuit board, a driving motor, a speed reduction mechanism and an output shaft, etc., which are basically the same as the internal components of the existing steering gear, thus not described again). The first housing 131 and the second housing 132 are fixedly connected to each other to form an assembly inner space, specifically, the first housing 131 and the second housing 132 are fixedly connected by screwing a plurality of screws therebetween, and the internal components are installed in the assembly inner space. The output end housing 133 is installed on the output shaft of the internal components, and the output end housing 133 and the output shaft rotate synchronously, that is, the output end housing 133 rotates relative to the first housing 131 and the second housing 132. Specifically, the output shaft of the internal components extends from one end of the second housing 132 away from the first housing 131, and the output end housing 133 is located at the one end of the second housing 132 away from the first housing 131. Further, the first housing 131 is provided with a plurality of mounting lugs 1311, which are uniformly arranged around the central axis of the first housing 131, and preferably, the first housing 131 is provided with two opposite mounting lugs 1311. Moreover, each mounting lug 1311 is hollow, so that the cable of the internal components can be arranged in the hollow mounting lug 1311, or a plug-in terminal is installed in the hollow mounting lug 1311, and then the cable of the internal components is connected to the plug-in terminal. A plurality of insertion ports 1331 and clamping grooves 1332 corresponding to the insertion ports 1331 are formed on the side wall of the one end of the output end housing 133 away from the first housing 131, and the insertion ports 1331 are circumferentially spaced apart around the central axis of the output end housing 133. Preferably, the output end housing 133 is provided with two opposite insertion ports 1331 and corresponding two clamping grooves 1332.

[0052] As shown in Figure 1 and Figure 2 Two driving members 13 are assembled to the connecting arm 12, one of which is installed at the first end of the connecting arm 12, and the other of which is installed at the second end of the connecting arm 12. Specifically, the first end of the connecting arm 12 is formed by the first end of the first outer support housing 121, the first end of the second outer support housing 122 and the first end of the rotating inner support housing 123; and the second end of the connecting arm 12 is formed by the second end of the first outer support housing 121, the second end of the second outer support housing 122 and the second end of the rotating inner support housing 123.

[0053] As shown in Figure 1 and Figure 2As shown, when one of the driving members 13 is installed to the first end of the connecting arm 12, specifically, the output end shell 133 of the driving member 13 is installed to the first end of the connecting arm 12. Specifically, the output end shell 133 is inserted into the first sleeve 1211, and the two locking protrusions 1235 are inserted into the two corresponding insertion openings 1331. Wherein, before the output end shell 133 is inserted into the first sleeve 1211, the third frame edge 1234 of the rotating inner support shell 123 is first turned out from between the first avoiding opening 1231 and the second avoiding opening 1232, and then passed through the first avoiding opening 1231 or the second avoiding opening 1232. After the output end shell 133 is inserted into the first sleeve 1211, the rotating inner support shell 123 is then turned back to the position between the first avoiding opening 1231 and the second avoiding opening 1232, at this time, the locking protrusions 1235 slide into the locking slot 1332 along the locking slot 1332, and one side slot wall of the locking slot 1332 is stopped by the locking protrusions 1235 and the stopping protruding edge 1224, at this time, one side slot wall of the locking slot 1332 abuts against the stopping protruding edge 1224. In this way, the driving member 13 is completed to be installed to the first end of the connecting arm 12.

[0054] As Figure 1 and Figure 2As shown, when the other driving member 13 is installed to the second end of the connecting arm 12, specifically, the first housing 131 of the driving member 13 is installed to the second end of the connecting arm 12. Specifically, when the driving member 13 installed to the first end of the connecting arm 12 is inserted into the first sleeve 1211, at the same time, the driving member 13 installed to the second end of the connecting arm 12 is placed into the runway-shaped space formed by the abutment of the first frame 1212 and the second frame 1222, and one of the two installation lugs 1311 on the first housing 131 of the driving member 13 passes through the first installation through hole 1214. Then, in the process of rotating the inner rotating bracket housing 123 back to the position between the first avoiding port 1231 and the second avoiding port 1232, the other installation lug 1311 on the first housing 131 of the driving member 13 corresponds to enter the recessed groove 1237, and slides along the recessed groove 1237 until the installation lug 1311 passes into the second installation through hole 1236. In the process of sliding the installation lug 1311 along the recessed groove 1237, the second frame 1222 is slightly elastically deformed by the extrusion of the installation lug 1311, so that the installation lug 1311 can slide along the recessed groove 1237 and pass into the second installation through hole 1236. In this way, the two installation lugs 1311 pass into the first installation through hole 1214 and the second installation through hole 1236 respectively, so as to limit the first housing 131 from being detached from the second end of the connecting arm 12, and the two installation lugs 1311 abut against the first frame 1212 and the second frame 1222 respectively, so as to clamp the first housing 131 between the first frame 1212 and the second frame 1222 without loosening.

[0055] After the two driving members 13 are placed in the corresponding positions of the first end and the second end of the connecting arm 12 respectively, the inner rotating bracket housing 123 is rotated back to the position between the first avoiding port 1231 and the second avoiding port 1232, so that the two driving members 13 can be installed on the connecting arm 12 at the same time.

[0056] As Figure 7As shown, the wheel 11 includes a support shell 111, a rotating end cap 112, and a tire 113. The tire 113 is integrally molded from rubber and has a certain degree of elasticity, allowing it to expand elastically and fit snugly onto the outer circumferential surface of the support shell 111 as the wheel tread. The support shell 111 has a receiving space 1111, and the inner wall of the receiving space 1111 has multiple cantilever arms 1112 arranged circumferentially, preferably two centrally symmetrical cantilever arms 1112. Furthermore, the inner wall of the receiving space 1111 has a stepped surface 1113 corresponding to the cantilever arms 1112, and an assembly opening 1114 is formed between the free end of the cantilever arm 1112 and the stepped surface 1113. The inner sidewall of the rotating end cap 112 has multiple radially extending latches 1121, preferably two oppositely arranged latches 1121. When the rotating end cap 112 is installed onto the support shell 111, the two latches 1121 are aligned with the two mounting openings 1114 respectively, allowing the mounting openings 1114 to open slightly, thus enabling the latches 1121 to enter between the cantilever 1112 and the stepped surface 1113. Under normal circumstances, when the mounting openings 1114 are not expanded, the latches 1121 are difficult to disengage from between the cantilever 1112 and the stepped surface 1113, thereby confining the rotating end cap 112 to the support shell 111. Furthermore, the latches 1121 can rotate and slide between the cantilever 1112 and the stepped surface 1113.

[0057] like Figure 7 As shown, when assembling the wheel 11 and the drive unit 13, specifically, the wheel 11 is installed onto the output end housing 133. The output end housing 133 of the drive unit 13 is inserted into the receiving space 1111, and the insertion port 1331 and the corresponding latch 1121 are aligned with each other until the latch 1121 enters the insertion port 1331. Then, the rotating end cover 112 is rotated, causing the latch 1121 to slide into the latch groove 1332. In this way, one side wall of the latch groove 1332 is stopped by the latch 1121 and the cantilever 1112, and at this time, one side wall of the latch groove 1332 abuts against the cantilever 1112. Thus, the installation of the wheel 11 and the drive unit 13 is completed, and the drive wheel module (the drive wheel module corresponds to the second end of the connecting arm 12) is assembled.

[0058] like Figures 8 to 13 As shown, the educational robot also includes a body body 20. After the four wheel sets 10 are assembled, the four wheel sets 10 can be assembled onto the body body 20, thereby completing the structural assembly of the wheeled walking system of the educational robot.

[0059] like Figures 8 to 13 As shown, the vehicle body 20 includes a body frame 21 and a floor cover 22. The body frame 21 has an accommodating space 211, such as... Figure 13As shown, the accommodation space 211 is used to install the fixed battery 40, master module 30 and other components. The bottom cover 22 is installed and fixed to the bottom of the vehicle body frame 21 by a plurality of bolts 23. The main body profile shape of the vehicle body frame 21 is a cuboid, and both sides of the bottom of the vehicle body frame 21 are provided with open accommodation grooves 212 along the direction of travel of the educational robot. Furthermore, a plurality of first insertion grooves 213 are provided on the groove wall of the side of the accommodation groove 212 opposite the bottom cover 22, and specifically, three first insertion grooves 213 are provided on the groove wall of each side of the accommodation groove 212 of the vehicle body frame 21. Correspondingly, a plurality of second insertion grooves 221 are provided on both sides of the bottom cover 22 along the direction of travel of the educational robot, and the plurality of second insertion grooves 221 and the plurality of first insertion grooves 213 correspond one-to-one, that is, three second insertion grooves 221 are provided on both sides of the bottom cover 22.

[0060] As shown in Figure 8 and Figure 9 After the assembly of each wheel group structure 10 is completed, the first housing 131 of the driving member 13 at the first end of the connecting arm 12 in each wheel group structure 10 will be installed and fixed to the vehicle body main body 20. As shown in Figure 9 , taking the assembly process of one of the wheel group structures 10 assembled to the left rear end position of the vehicle body main body 20 as an example. Specifically, one of the two mounting lugs 1311 of the first housing 131 of the driving member 13 at the first end of the connecting arm 12 is inserted into the first insertion groove 213 at the left rear end position of the vehicle body frame 21, and then the bottom cover 22 is closed to the bottom of the vehicle body frame 21, so that the other mounting lug 1311 is aligned and inserted into the second insertion groove 221 at the left rear end position of the bottom cover 22, and then the bolts 23 are screwed to connect and fix the bottom cover 22 to the bottom of the vehicle body frame 21. At this time, the two mounting lugs 1311 are respectively inserted into the first insertion groove 213 and the second insertion groove 221, thereby restricting the driving member 13 from being separated from the vehicle body frame 21 and the bottom cover 22. Furthermore, the groove wall of the accommodation groove 212 is provided with a first abutting recess 214 corresponding to the position of each first insertion groove 213, which is adapted to the corresponding outer wall position of the first housing 131, and the bottom cover 22 is provided with a second abutting recess 222 corresponding to the position of each second insertion groove 221, which is adapted to the corresponding outer wall position of the first housing 131. When the bottom cover 22 is connected and fixed to the bottom of the vehicle body frame 21 by the bolts 23, the first abutting recess 214 and the second abutting recess 222 respectively abut the corresponding outer wall position of the first housing 131, thereby clamping and fixing the first housing 131, preventing the driving member 13 from shaking relative to the vehicle body main body 20, that is, preventing the wheel group structure 10 from shaking relative to the vehicle body main body 20.

[0061] As shown in Figure 9 and Figure 11As shown, the front end and the rear end of the vehicle body frame 21 are both provided with a third insertion slot 215 along the direction of travel of the educational robot, and correspondingly, the front end and the rear end of the bottom cover 22 are both provided with a fourth insertion slot 223, and the third insertion slot 215 at the front end of the vehicle body frame 20 is opposite to the fourth insertion slot 223, and the third insertion slot 215 at the rear end of the vehicle body frame 20 is opposite to the fourth insertion slot 223. And the front end of the vehicle body frame 21 is provided with a third abutting recess 216 corresponding to the position of the third insertion slot 215, and the rear end of the vehicle body frame 21 is provided with a third abutting recess 216 corresponding to the position of the third insertion slot 215. Correspondingly, the front end of the bottom cover 22 is provided with a fourth abutting recess 224 corresponding to the position of the fourth insertion slot 223, and the rear end of the bottom cover 22 is provided with a fourth abutting recess 224 corresponding to the position of the fourth insertion slot 223.

And the front end of the vehicle body frame 21 is provided with a third abutting recess 216 corresponding to the position of the third insertion slot 215, and the rear end of the vehicle body frame 21 is provided with a third abutting recess 216 corresponding to the position of the third insertion slot 215. Correspondingly, the front end of the bottom cover 22 is provided with a fourth abutting recess 224 corresponding to the position of the fourth insertion slot 223, and the rear end of the bottom cover 22 is provided with a fourth abutting recess 224 corresponding to the position of the fourth insertion slot 223.

[0063] The balance car type educational robot uses a gyroscope (not shown) to detect the overall balance of the intelligent vehicle. The gyroscope and the main control module 30 are electrically connected. When the gyroscope detects that the overall balance of the intelligent vehicle is unbalanced, the gyroscope sends an unbalanced signal to the main control module 30, and then the main control module 30 sends an adjustment signal to the two drive members 13 of the drive wheel module according to the unbalanced signal after receiving the unbalanced signal, so that the two drive members 13 quickly respond to adjust the overall balance of the intelligent vehicle, so that the intelligent vehicle restores balance.

[0064] As shown in the accompanying drawings, Figure 13As shown, the assembly is performed for the master module 30 and the battery 40, thus the accommodation space 211 is divided into a lower space with a smaller space volume and an upper space with a larger space volume, and the lower space is directly extended at the bottom of the upper space, that is, the upper space and the lower space are communicated with each other. The battery 40 is installed in the lower space, and the master module 30 is installed in the upper space. Moreover, the horizontal circumferential contour shape of the upper space is matched with the contour shape of the master module 30, and the horizontal circumferential contour shape of the lower space is matched with the contour shape of the battery 40 (the horizontal circumferential direction refers to the circumferential direction of an object in the horizontal direction when the vehicle body frame 21 is placed horizontally on a flat ground in a normal posture). Further, the space height of the upper space is matched with the thickness of the master module 30, and the space height of the lower space is matched with the height of the battery 40, so that the master module 30 is directly stacked on the battery 40 and the corresponding terminal contacts between them are directly contacted to realize the electrical connection between them.

[0065] As shown in the figure, Figure 13 As shown, the side wall of the battery 40 is provided with an elastic buckle 41, and the corresponding side wall of the lower space is provided with a clamping interface 2113 matched with the elastic buckle 41. Specifically, along the direction of the educational robot, the front side wall and the rear side wall of the battery 40 are each provided with an elastic buckle 41, and the front side wall and the rear side wall of the lower space are also provided with clamping interfaces 2113. When the battery 40 is placed into the lower space, the elastic buckle 41 is clamped into the clamping interface 2113, thereby preventing the battery 40 from being taken out of the lower space and preventing the battery 40 from moving up and down. After the battery 40 is placed, the master module 30 is directly placed into the upper space.

[0066] The vehicle body main body 20 further comprises a top cover 24.

[0067] In the educational robot of the present application, the top cover 24 can be detachably covered on the top of the vehicle body frame 21 through the clamping structure and locked with the corresponding clamping matching structure, so as to cover the master module 30 placed in the upper space and prevent the master module 30 from being taken out of the upper space. Moreover, the inner wall of the top cover 24 abuts against the top wall of the master module 30, so that the master module 30 is fixed between the top cover 24 and the battery 40. The top cover 24 can be detached from the vehicle body frame 21 by disengaging the clamping structure, and then the components such as the master module 30, the battery 40 and the like can be maintained, replaced and the like.

[0068] In an embodiment, the top cover 24 is locked on the top of the vehicle body frame 21 by a plurality of screws, so as to cover the master control module 30 placed in the upper space and prevent the master control module 30 from being taken out of the upper space. In addition, the inner wall of the top cover 24 abuts against the top wall of the master control module 30, so that the master control module 30 is fixed between the top cover 24 and the battery 40. The top cover 24 can be detached from the vehicle body frame 21 by detaching the screws, and then the master control module 30, the battery 40 and other components can be maintained, replaced and the like.

[0069] In an embodiment, as shown in Figure 13 , one side of the top cover 24 is reversibly installed on the vehicle body frame 21 by a pin shaft 25, and the other side of the top cover 24 opposite to the pin shaft 25 is provided with a barb, and the corresponding position of the vehicle body frame 21 is provided with a buckle 217. When the top cover 24 is reversed around the pin shaft 25 to cover the top of the vehicle body frame 21, the barb and the buckle 217 are locked with each other, so as to cover the master control module 30 placed in the upper space and prevent the master control module 30 from being taken out of the upper space. In addition, the inner wall of the top cover 24 abuts against the top wall of the master control module 30, so that the master control module 30 is fixed between the top cover 24 and the battery 40. The top cover 24 can be reversed around the pin shaft 25 from the vehicle body frame 21 by unlocking the barb and the buckle 217, and then the master control module 30, the battery 40 and other components can be maintained, replaced and the like.

[0070] As shown in Figure 15 and Figure 16 , the educational robot further comprises a mechanical arm 50, which is detachably installed on the vehicle body frame 21 by an adapter 51.

[0071] As shown in Figure 13 and Figure 14 , along the traveling direction of the educational robot, the left and right sides of the top opening of the vehicle body frame 21 are each provided with a plurality of entry ports 218 and a plurality of clamping grooves 219, the plurality of clamping grooves 219 and the plurality of entry ports 218 are one-to-one correspondingly communicated, and each clamping groove 219 is located in the same side direction of the corresponding entry port 218. Specifically, the left and right sides of the top opening of the vehicle body frame 21 are each provided with two entry ports 218 and two clamping grooves 219. In addition, when the vehicle body frame 21 is placed on the horizontal ground, each clamping groove 219 extends horizontally.

[0072] As shown in Figure 15 and Figure 16 , along the traveling direction of the educational robot, the left and right sides of the adapter 51 are each provided with a plurality of clamping blocks 511. Specifically, the left and right sides of the adapter 51 of the present embodiment are each provided with two clamping blocks 511.

[0073] When the mechanical arm 50 is assembled to the vehicle body frame 21 through the adapter 51, the top cover 24 needs to be removed from the top of the vehicle body frame 21 first, so that each access opening 218 on the top of the vehicle body frame 21 is exposed. Then, each clamping block 511 of the adapter 51 is aligned with the corresponding access opening 218, so that each clamping block 511 enters the corresponding access opening 218. Then, the adapter 51 is pushed horizontally, so that each clamping block 511 slides into the corresponding clamping groove 219. In this way, the adapter 51 is clamped and fixed on the vehicle body frame 21, that is, the mechanical arm 50 is assembled on the vehicle body frame 21 through the adapter 51.

[0074] In order to prevent the clamping block 511 from sliding out of the clamping groove 219 and causing the mechanical arm 50 to be separated from the vehicle body frame 21, the upper surface (and / or the lower surface) of each clamping block 511 is provided with at least one anti-disengagement protrusion 512, as shown in Figure 15 Correspondingly, the upper groove wall (and / or the lower groove wall) of the clamping groove 219 is provided with at least one matching protrusion 2191, as shown in Figure 14 During the sliding of the clamping block 511 into the clamping groove 219, the anti-disengagement protrusion 512 abuts and presses the matching protrusion 2191, and the anti-disengagement protrusion 512 passes over the matching protrusion 2191. In this way, the matching protrusion 2191 can block the anti-disengagement protrusion 512, so as to prevent the clamping block 511 from sliding out of the clamping groove 219.

[0075] In the embodiment, a plurality of matching protrusions 2191 are arranged on the same side wall of the clamping groove 219, and the plurality of matching protrusions 2191 are arranged in sequence and at intervals. When the clamping block 511 slides into the clamping groove 219, the clamping block 511 can be adjusted to be blocked by any matching protrusion 2191, so as to prevent the clamping block 511 from sliding out of the clamping groove 219. Further preferably, the interval between any two adjacent matching protrusions 2191 is equal to the width of the clamping block 511.

[0076] When it is necessary to disassemble the mechanical arm 50 from the vehicle body frame 21, the adapter 51 only needs to be pulled with force, so that the clamping block 511 slides towards the direction of the access opening 218. Then, the anti-disengagement protrusion 512 abuts and presses the matching protrusion 2191 again, and then passes over the matching protrusion 2191, so as to disengage the clamping block 511 from the access opening 218.

[0077] The mechanical arm 50 is an extensible mechanical arm, that is, the extension length of the mechanical arm 50 can be extended, and the activity freedom and activity flexibility of the mechanical arm 50 are not affected. As shown in Figure 15 and Figure 16As shown, the mechanical arm 50 comprises a head end section arm 513, a terminal section arm 514, at least one connecting arm 12 and a plurality of driving members 13. The following will be described by taking the mechanical arm 50 provided with only one connecting arm 12 as an example to illustrate the structural design of the mechanical arm 50.

[0078] As shown in Figure 17 and Figure 18 , the head end section arm 513 is provided with a first section arm support shell 5131, a head end main support 5132 and a head end auxiliary support 5133.

[0079] As shown in Figure 18 , the head end main support 5132 is provided with a first fork-shaped portion and a first curved portion, the first curved portion is shaped as a half track type, and the two ends of the half track type of the first curved portion have two connecting positions with the first fork-shaped portion, the connecting line direction of the two connecting positions is perpendicular to the connecting line direction of the two fork arms of the first fork-shaped portion. The first section arm support shell 5131 and the two fork arms of the first fork-shaped portion are fixedly connected and located between the two fork arms of the first fork-shaped portion. The position of the first curved portion opposite to the first section arm support shell 5131 is provided with a first fixed through hole 5134, and the inner wall of the elbow position of the first curved portion is smoothly arranged.

[0080] As shown in Figure 18 , the head end auxiliary support 5133 is provided with a second fork-shaped portion and a second curved portion, the second curved portion is shaped as a half track type, and the two ends of the half track type of the second curved portion have two connecting positions with the second fork-shaped portion, the connecting line direction of the two connecting positions is perpendicular to the connecting line direction of the two fork arms of the second fork-shaped portion. The two fork arms of the second fork-shaped portion are rotatably installed on the first section arm support shell 5131, and the first section arm support shell 5131 is located between the two fork arms of the second fork-shaped portion. The position of the second curved portion opposite to the first section arm support shell 5131 is provided with a second fixed through hole 5135, and the outer wall of the elbow position of the second curved portion is smoothly arranged. The outer wall of the second curved portion corresponding to the second fixed through hole 5135 is provided with a head end recess groove 5136, and the extension direction of the head end recess groove 5136 is consistent with the extension direction of the track type of the second curved portion.

[0081] That is, the first fork-shaped portion and the second fork-shaped portion jointly constitute a first end portion of the U-shaped structure of the head end section arm 513, and the first curved portion and the second curved portion jointly constitute a second end portion which is curvedly shaped, and the first end portion and the second end portion are orthogonally arranged. In a specific application of the head end section arm 513, the output end shell of one driving member 13 is fixedly installed on the first end portion of the head end section arm 513 (i.e. the output end shell of the driving member 13 is fixedly installed on the first section arm support shell 5131 fixedly connected with the two fork arms of the first fork-shaped portion), and the shell of another driving member 13 is fixedly installed on the second end portion of the head end section arm 513.

[0082] As shown in Figure 18 The first arm support shell 5131 includes a head end sleeve shell 51311 and a head end rotating end cover 51312, both of the two fork arms of the first forked part and both of the two fork arms of the second forked part are connected to the two side outer walls of the head end sleeve shell 51311, and the head end rotating end cover 51312 is rotationally installed to the head end sleeve shell 51311. Specifically, the head end sleeve shell 51311 is provided with a head end placing space 51313, and the inner wall of the head end placing space 51313 is provided with a plurality of head end cantilever arms 51314 arranged in a circumferential direction, preferably two head end cantilever arms 51314 arranged in a central symmetry. Moreover, the inner wall of the head end placing space 51313 is provided with a head end stepped surface 51315 corresponding to the head end cantilever arms 51314, and a head end assembly opening 51316 is formed between the free ends of the head end cantilever arms 51314 and the head end stepped surface 51315. The inner side wall of the head end rotating end cover 51312 is provided with a plurality of head end lugs 51317 extending in a radial direction, preferably two head end lugs 51317 arranged oppositely. When the head end rotating end cover 51312 is installed to the head end sleeve shell 51311, the two head end lugs 51317 are respectively corresponding to the two head end assembly openings 51316, so that the head end assembly openings 51316 are slightly expanded, and thus the head end lugs 51317 enter between the head end cantilever arms 51314 and the head end stepped surface 51315. Normally, when the head end assembly openings 51316 are not expanded, the head end lugs 51317 are difficult to be separated from between the head end cantilever arms 51314 and the head end stepped surface 51315, so as to limit the head end rotating end cover 51312 on the head end sleeve shell 51311. Moreover, the head end lugs 51317 can rotationally slide between the head end cantilever arms 51314 and the head end stepped surface 51315, and the head end lugs 51317 are arranged in a spaced manner with the head end cantilever arms 51314.

[0083] As shown in Figure 16 When the driving member 13 is installed to the first arm support shell 5131, specifically, the output end shell 133 of the driving member 13 is installed to the first arm support shell 5131. The output end shell 133 of the driving member 13 is inserted into the head end placing space 51313, and the insertion port 1331 and the corresponding head end lug 51317 are aligned with each other until the head end lug 51317 enters the insertion port 1331. Then, the head end rotating end cover 51312 is rotated, so that the head end lug 51317 slides into the slot 1332 along the slot 1332. In this way, one side slot wall of the slot 1332 is stopped by the head end lug 51317 and the head end cantilever arm 51314 matched with each other, and at this time, the one side slot wall of the slot 1332 abuts against the head end cantilever arm 51314. In this way, the installation of the driving member 13 and the first arm support shell 5131 is completed.

[0084] Then, the other driving member 13 is installed to the second end of the head link arm 513, specifically, the first housing 131 of the driving member 13 is installed between the first bending part and the second bending part. As shown in Figure 16 the second bending part is first rotated out so that the second fixed through hole 5135 is no longer opposite to the first fixed through hole 5134, then the first housing 131 of the driving member 13 is put into the half track type space of the first bending part, and one mounting lug 1311 of the first housing 131 of the driving member 13 is inserted into the first fixed through hole 5134. Then, the second bending part is rotated back into the head main support 5132, and the other mounting lug 1311 of the first housing 131 of the driving member 13 is correspondingly inserted into the head recessed groove 5136 and slides along the head recessed groove 5136 until the mounting lug 1311 is inserted into the second fixed through hole 5135. During the sliding of the mounting lug 1311 along the head recessed groove 5136, the second bending part is slightly elastically deformed by the extrusion of the mounting lug 1311, so that the mounting lug 1311 can slide along the head recessed groove 5136 and be inserted into the second fixed through hole 5135. In this way, the two mounting lugs 1311 are respectively inserted into the first fixed through hole 5134 and the second fixed through hole 5135, so that the first housing 131 is limited and cannot be separated from the second end, and the two mounting lugs 1311 respectively abut against the inner wall of the first bending part and the outer wall of the second bending part, so that the first housing 131 is clamped between the head main support 5132 and the head auxiliary support 5133 and cannot be loosened.

[0085] Then, the output end housing 133 of the driving member 13 installed to the second end of the head link arm 513 is installed to the first end of the connecting arm 12. Then, the third driving member 13 of the mechanical arm 50 is installed to the second end of the connecting arm 12.

[0086] Finally, the end link arm 514 and the output end housing 133 of the third driving member 13 are installed, and the mechanical arm 50 provided with only one connecting arm 12 is assembled.

[0087] As shown in Figure 19 and Figure 20As shown, the end link arm 514 comprises a tail rotating end cover 5140, a tail sleeve 5141 and a tail operating part 5142, and the tail operating part 5142 is fixedly connected to the outer wall of the tail sleeve 5141. The tail operating part 5142 can be a humanoid palm, a suction cup assembly, a fork or a mechanical clamp device. The tail operating part 5142 of the embodiment is preferably a mechanical clamp device, which is widely used in the prior art and will not be described here. Specifically, the tail sleeve 5141 is provided with a tail placing space 5143, and the inner wall of the tail placing space 5143 is provided with a plurality of tail cantilever arms 5144 arranged in a circumferential direction, preferably two tail cantilever arms 5144 arranged in a central symmetry. Moreover, the inner wall of the tail placing space 5143 is provided with a tail stepped surface 5145 corresponding to the tail cantilever arm 5144, and a tail assembly opening 5146 is formed between the free end of the tail cantilever arm 5144 and the tail stepped surface 5145. The inner side wall of the tail rotating end cover 5140 is provided with a plurality of tail lugs 5147 extending in a radial direction, preferably two tail lugs 5147 arranged oppositely. When the tail rotating end cover 5140 is installed to the tail sleeve 5141, the two tail lugs 5147 are respectively corresponding to the two tail assembly openings 5146, so that the tail assembly openings 5146 are slightly opened, so that the tail lugs 5147 enter between the tail cantilever arms 5144 and the tail stepped surface 5145. Under normal circumstances, when the tail assembly openings 5146 are not expanded, the tail lugs 5147 are difficult to separate from between the tail cantilever arms 5144 and the tail stepped surface 5145, thereby limiting the tail rotating end cover 5140 on the tail sleeve 5141. Moreover, the tail lugs 5147 can rotate and slide between the tail cantilever arms 5144 and the tail stepped surface 5145. The output end shell 133 of the third driving member 13 is inserted into the tail placing space 5143, so that the insertion port 1331 and the corresponding tail lug 5147 are aligned with each other, until the tail lug 5147 enters the insertion port 1331. Then, the tail rotating end cover 5140 is rotated, so that the tail lug 5147 slides into the slot 1332 along the slot 1332. In this way, one side of the slot 1332 is stopped by the tail lug 5147 and the tail cantilever arm 5144, and at this time, one side of the slot 1332 abuts against the tail cantilever arm 5144.

[0088] When it is necessary to expand the extension length of the mechanical arm 50, the number of the connecting arms 12 and the number of the driving members 13 required to be added can be selected according to the actual extension length required to be expanded by the mechanical arm 50, and all the connecting arms 12 and the driving members 13 are sequentially connected to form an expansion module of the mechanical arm 50. Then, the expansion module connected in series is connected in series with the head end link arm 513 and the tail end link arm 514 to complete the expansion of the mechanical arm 50.

[0089] As shown in Figure 15 and Figure 16 illustrated, the driving member 13 and the adapter 51 of the mechanical arm 50 are connected and fixed to the first arm support shell 5131. Specifically, the adapter 51 includes an adapter plate frame 5101, a first adapter seat shell 5102 and a second adapter seat shell 5103.

[0090] As shown in Figure 15 and Figure 16 illustrated, along the direction of travel of the educational robot, the left and right sides of the adapter plate frame 5101 are each protrudingly provided with a plurality of clamping blocks 511, preferably two clamping blocks 511. When the adapter plate frame 5101 is installed on the vehicle body frame 21, the inner surface of the adapter plate frame 5101 abuts against the main control module 30, thereby stably fixing the main control module 30 in the vehicle body frame 21.

[0091] As shown in Figure 16 illustrated, the first adapter seat shell 5102 can be a separate component relative to the adapter plate frame 5101, at which time the first adapter seat shell 5102 is fixedly installed on the adapter plate frame 5101 by a plurality of screws; the first adapter seat shell 5102 can also be an integral structural component of the adapter plate frame 5101. As shown in Figure 16 illustrated, the first adapter seat shell 5102 includes a bottom shell 51021, a first side wall 51022 and a second side wall 51023. In this embodiment, the bottom shell 51021 is preferably fixedly installed on the adapter plate frame 5101 by a plurality of screws. The first side wall 51022 and the second side wall 51023 are connected to the bottom shell 51021 in opposition, so that two opposite limiting notches 51024 are formed between the first side wall 51022 and the second side wall 51023. Moreover, the end walls of the first side wall 51022 and the second side wall 51023 away from the bottom shell 51021 are each provided with a first buckling protrusion 51025.

[0092] As shown in Figure 16 illustrated, the second adapter seat shell 5103 is provided with a through channel 51031, the inner wall of the through channel 51031 is provided with two opposite avoidance grooves 51032 and two opposite second buckling protrusions 51033, and the lines between the two avoidance grooves 51032 and the two second buckling protrusions 51033 are perpendicular to each other. The second buckling protrusion 51033 and the first buckling protrusion 51025 cooperate with each other to limit the second adapter seat shell 5103 on the first adapter seat shell 5102.

[0093] Specifically, when the first adapter housing 5102 is a separate component relative to the adapter plate frame 5101, the bottom shell 51021, the first side wall 51022, and the second side wall 51023 of the first adapter housing 5102 pass through the through-pass 51031. Then, the bottom shell 51021 is fixedly installed on the adapter plate frame 5101 by multiple screws. At this time, the first latching protrusion 51025 blocks the second latching protrusion 51033, so the second adapter housing 5103 cannot detach from the first adapter housing 5102.

[0094] Furthermore, when the first adapter housing 5102 and the adapter plate frame 5101 are integrally formed, the first side wall 51022 and the second side wall 51023 need to be brought together, then inserted into the through-passage 51031, and then the first side wall 51022 and the second side wall 51023 are released. In this way, the first latching protrusion 51025 blocks the second latching protrusion 51033, so the second adapter housing 5103 cannot detach from the first adapter housing 5102.

[0095] like Figure 16 As shown, when the robotic arm 50 is assembled with the drive component 13 and the adapter component 51 of the first arm support housing 5131, the two clearance grooves 51032 of the second adapter housing 5103 are aligned with the two limiting notches 51024 of the first adapter housing 5102. Then, the two mounting lugs 1311 of the drive component 13 enter the two limiting notches 51024 through the two clearance grooves 51032, and the mounting lugs 1311 abut against the bottom of the limiting notches 51024. At this point, the outer wall surface of the mounting lug 1311 facing away from the bottom of the limiting notch 51024 is basically flush with the wall surface of the second latching protrusion 51033 facing the first adapter housing 5102. Then, the second adapter housing 5103 is rotated so that the mounting lug 1311 is clamped between the bottom of the second latching protrusion 51033 and the limiting notch 51024. At this time, the two ends of each first latching protrusion 51025 are respectively fastened to the side surface of the two second latching protrusions 51033 facing the drive member 13. Furthermore, the end face openings of the two mounting lugs 1311 are exposed between the first adapter housing 5102 and the second adapter housing 5103, thereby facilitating the installation of the plug-in terminal.

[0096] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
