[0027] Example 1

[0028] The following description, in conjunction with the accompanying drawings, illustrates the vehicle frame disclosed in this utility model. Figure 1 As shown, it includes a rectangular frame 100, which includes two support columns 110 arranged in the vertical direction. The upper ends of the two support columns 110 are connected by an upper connecting beam 120, and the lower ends of the two support columns 110 are connected by a lower connecting beam 130. Lifting mechanisms 200 are respectively provided at the two support columns 110.

[0029] The structure of the lifting mechanism 200 can be designed as needed. In one embodiment, as shown in the attached figure... Figure 1As shown, the lifting mechanism 200 includes a lead screw 210 rotatably disposed in the support column 110. The lead screw 210 extends vertically, and its two ends are rotatably disposed in the support column 110 via bearings 220. At the same time, the movable nut of the lead screw 210 is connected to a lifting seat 230 that can slide along the support column 110. The top or bottom of the support column 110 is provided with a motor 240 that drives the screw of the lead screw 210 to rotate. The motor 240 is preferably a right-angle geared motor, which is located in the upper connecting beam 120 or the lower connecting beam 130. Correspondingly, the cross-sectional shape of the upper connecting beam 120 and / or the lower connecting beam 130 is U-shaped. At the same time, in order to facilitate the connection between the upper connecting beam 120 and the lower connecting beam 130 and the support column 110, the parallel support plates on both sides of the upper connecting beam 120 and the lower connecting beam 130 are C-shaped. During operation, the motor 240 drives the screw of the lead screw 210 to rotate, and the movable nut drives the lifting seat 230 to slide up and down along the support column 110 to adjust its position.

[0030] In another embodiment, as shown in the appendix Figure 2 As shown, the lifting mechanism 200 includes an upper drive wheel 250 and a lower drive wheel 260. The upper drive wheel 250 and the lower drive wheel 260 are respectively rotatably mounted on mounting seats 140 at the top and bottom of the support column 110. The mounting seats 140 are located inside the upper connecting beam 120 and the lower connecting beam 130. A drive belt 270 is fitted on the upper drive wheel 250 and the lower drive wheel 260. The drive belt 270 is connected to a lifting seat 230 that can slide along the support column 110. The upper drive wheel 250 or the lower drive wheel 260 is connected to a motor 240 that drives its rotation. To avoid interference between motors 240 when adjacent sorting carts are connected, the axes of the upper drive wheel 250 and lower drive wheel 260 of at least one lifting mechanism 200 are perpendicular to the extension direction of the upper connecting rod. In this case, the motor 240 is located on the side of the rectangular frame 100. Preferably, the axes of the upper drive wheel 250 and lower drive wheel 260 of both lifting mechanisms 200 are perpendicular to the extension direction of the upper connecting rod. The motor 240 can be a known geared motor. During operation, the motor 240 drives the upper drive wheel 250 or the lower drive wheel 260 to rotate, which in turn drives the drive belt 270 to rotate. The drive belt 270 causes the lifting seat 230 to slide up and down along the support column 110.

[0031] As attached Figure 3As shown, the upper connecting beam 120 is provided with at least one top limiting wheel 300 whose axis extends vertically. Two mounting shafts 400 extending vertically are symmetrically arranged on the top of the upper connecting beam 120, and the top of each mounting shaft 400 is rotatably provided with the top limiting wheel 300. Simultaneously, a fisheye spherical bearing 500 is also provided on each of the two mounting shafts 400. The inner ring of the fisheye spherical bearing 500 is fitted onto the mounting shaft 400. Furthermore, a rigid connecting rod or an elastic connecting rod 600 is coaxially screwed to the connecting rod of one side of the fisheye spherical bearing 500.

[0032] As attached Figure 3 Appendix Figure 4 As shown, the lower connecting beam 130 is connected to the movable frame 800 via two fine-tuning components 700. Each fine-tuning component 700 is located at the bottom of the lower connecting beam 130 and includes a bearing seat 710 and a spherical bearing 720 mounted on the bearing seat 710. The outer ring of the spherical bearing 720 is an inner spherical surface, and the inner ring of the spherical bearing 720 is an outer spherical surface that matches the inner spherical surface. The inner rings of the spherical bearings 720 of the two fine-tuning components 700 are respectively connected to a pin 810. The two pins 810 are perpendicular to each other and are mounted at the same height on the movable frame 800. The movable frame 800 includes a T-shaped first support rod 820 and a second support rod 830. The extension direction of the first support rod 820 is consistent with the extension direction of the upper connecting beam 120. Two pins 810 are provided on the first support rod 820, with one pin 810 located at the first end of the first support rod 820 and the other pin 810 close to the second end of the first support rod 820. The first support rod 820 also has clearance holes for the fine-tuning assembly 700 to connect to the pins 810. A mounting hole is provided at the second end of the first support rod 820, with the axis of the mounting hole extending vertically. A hinge bearing 840, which is a known spherical bearing, is provided at the mounting hole.

[0033] As attached Figure 4 As shown, the first end of the first support rod 820 is connected to the second support rod 830, and a connecting pin 850 for connecting the inner ring of the hinge bearing 840 is provided in the middle of the second support rod 830. Both ends of the second support rod 830 are provided with traveling wheels 860, the axes of which extend horizontally. The second support rod 830 is also provided with two lower limit wheels 870 located symmetrically distributed inside the two traveling wheels 860, the axes of which extend vertically.

[0034] Furthermore, a linear motor secondary assembly 880 may be installed at the bottom of the first support rod 820, and a sliding contact line current collector (not shown in the figure) may be installed on the side of the first support rod 820.
