[0024] Installation principle: The modular main drive wheel set 6 and the modular support wheel set 7 can be installed at the front or rear end of the main frame 1 as needed. The modular main drive wheel set 6 mainly provides power, and a motor is set inside to drive the drive wheels on both sides to rotate, while the modular support wheel set 7 is used for support and steering. Adjustment bolts can also be installed inside the bottom support frame 2 so that it can adapt to modular main drive wheel sets 6, modular support wheel sets 7 and modular power supply modules 8 of different widths to increase adaptability.

[0025] Rubber pads are provided on the contact surfaces of the bottom support frame 2, the side limit frame 3, the electric control inner limit frame 4 and the electric control outer limit frame 5 to improve cushioning and safety.

[0026] In order to cooperate with the lateral limitation, both sides of the modular main driving wheel group 6 and the modular supporting wheel group 7 are provided with lateral limiting slots 11 that cooperate with the side limiting frame 3 and the electronically controlled outer limiting frame 5.

[0027] In order to cooperate with the top support limit, the main frame 1 has an integrated transverse limit frame 12 located above the modular main driving wheel set 6 and the modular support wheel set 7.

[0028] The transverse limiting frame 12 limits the upper surfaces of the modular main drive wheel set 6 and the modular support wheel set 7 from the upper end, thereby ensuring the stability of the installation of the modular main drive wheel set 6 and the modular support wheel set 7.

[0029] In order to cooperate with lateral transmission adjustment, the inner walls on both sides of the main frame 1 are symmetrically provided with a first transmission groove 13 for installing and transmitting the electronically controlled inner limit frame 4 and a second transmission groove 14 for installing and transmitting the electronically controlled outer limit frame 5.

[0030] In order to cooperate with the inner adjustment, the electrically controlled inner limit frame 4 includes a first electrically controlled screw rod 41 movably installed inside the first transmission groove 13, a first internal thread adjustment block 42 threadedly mounted on the first electrically controlled screw rod 41, an internal control frame 43 with an inverted T-shaped structure fixed on the side wall of the first internal thread adjustment block 42, and an electrically controlled locking frame 44 installed at the upper end of the internal control frame 43.

[0031] The electric locking frame 44 includes a longitudinal screw rod installed inside the longitudinal section of the internal control frame 43, an internal thread top lifting seat threadedly sleeved on the longitudinal screw rod, and a top side limit frame fixed on the side wall of the internal thread top lifting seat.

[0032] Before installing the modular power supply module 8, first use the longitudinal screw rod to drive the internal thread top lifting seat to rise, and then adjust the first electric control screw rod 41 according to the number of modular power supply modules 8 that need to be installed, and use the first electric control screw rod 41 to drive the first internal thread adjustment blocks 42 on both sides to move horizontally along the first transmission groove 13, and then use the internal control frame 43 to drive the electric control locking frame 44 at its upper end to squeeze the outside of the modular power supply module 8 from both sides, and then control the electric control locking frame 44 to descend to lock and limit the upper end of the modular power supply module 8.

[0033] In order to cooperate with the electric control outer side adjustment limit, the transmission electric control outer side limit frame 5 includes a second electric control screw 51 movably installed in the second transmission groove 14, a second internal thread adjustment block 52 threadedly mounted on the second electric control screw 51, and a lateral limit frame 53 fixed on the side wall of the second internal thread adjustment block 52.

[0034] People first install the modular main drive wheel set 6 and the modular support wheel set 7 on the bottom of both sides of the main frame 1, and the lateral limit slot 11 at one end is clamped on the side limit frame 3 to limit it from the outside. Then, the second electric control screw 51 is controlled to rotate, driving the second internal thread adjustment block 52 to translate along the second transmission groove 14, so that the lateral limit frame 53 is inserted into the lateral limit slot 11 at the other end. In this way, the modular main drive wheel set 6 and the modular support wheel set 7 can be firmly installed on both sides of the bottom of the main frame 1.

[0035] In order to cooperate with the lateral assembly and fixation, bottom locking sleeves 15 for installing the modular lateral limit frames 9 are fixedly installed on both sides of the upper surface of the main frame 1, and locking bolts 16 for fixing the modular lateral limit frames 9 are inserted inside the bottom locking sleeves 15.

[0036] In order to cooperate with lateral support and limitation, the modular lateral limit frame 9 includes a lateral limit frame 91, a lateral locking sleeve 92 fixed on the upper and lower ends of the outer side of the lateral limit frame 91, and an upper support plate 93 and a lower support plate 94 movably installed inside the lateral limit frame 91.

[0037] The side limit frames on both sides are first fixed to the upper end of the main frame 1 by passing through the bottom locking sleeve 15 and the side locking sleeve 92 through the locking bolts 16, and then the horizontal storage grooves for installing the upper support plate 93 and the lower support plate 94 are opened in the internal cross beam of the side limit frame 91. The upper support plate 93 and the lower support plate 94 are respectively axially movably installed on both sides of the horizontal storage grooves. After the side limit frames on both sides are fixed to the two sides of the upper end of the main frame 1, the upper support plate 93 and the lower support plate 94 are flipped toward the inside of the horizontal storage grooves on the other side until the ends are inserted into the inside of the horizontal storage grooves, and the bolts are installed and limited. Then, the upper support plate 93 on one side and the lower support plate 94 on the other side are staggered to form an X-shaped support frame, which is installed and limited by the bolts located in the middle of the upper support plate 93 and the lower support plate 94. In this way, multiple bottom mounting brackets for supporting the modular storage box 10 can be formed.

[0038] In order to facilitate installation and improve fit, strip-shaped assembly openings 95 are opened inside the upper support plate 93 and the lower support plate 94.

[0039] In order to facilitate assembly, the lower surface of the modular storage box 10 has a downwardly protruding external thread positioning pin 17, and the upper end of the modular storage box 10 is provided with a top positioning hole 18 that cooperates with the external thread positioning pin 17.

[0040] The upper modular storage box is inserted into the top positioning hole 18 at the upper end of the lower modular storage box through the external thread positioning pin 17 at the bottom, and then the locking nut is put on the external thread positioning pin 17 to lock and fix it; The modular storage box 10 can also be inserted into the strip assembly port 95 through the external threaded positioning pin 17 at the bottom, and then the locking nut is put on the external threaded positioning pin 17 to lock and fix the modular storage box 10, the upper support plate 93 and the lower support plate 94.
