The elastic band 221 is connected to the first hanging ring 122 or the second hanging ring 23 through the hook 222. When the luggage needs to be fixed, the elastic band 221 is used to cover the luggage, and the other end of the elastic band 221 is buckled on the first hanging ring 122 through the hook 222, so that the two ends of the elastic band 221 are fixed, and the luggage can be tied to the vehicle bottom frame 1 or the diagonal support platform 12. When the luggage needs to be taken out, the hook 222 of the elastic band 221 is removed from the first hanging ring 122 to release the luggage, and the luggage can be taken out from the vehicle bottom frame 1 or the diagonal support platform 12, and the elastic band 221 can be hung on the second hanging ring 23 at the top of the support frame 2 through the hook 222 to prevent the elastic band 221 from swinging at will and affecting the taking of the luggage.

[0052] When the amount of luggage is large and the stacking height is high, the elastic band 221 is difficult to be stably tied. Therefore, the adjustment part 22 can be moved along the adjustment groove 21 to adjust the starting height of the elastic band 221 to adapt to the bundling of different amounts of luggage.

[0053] FIG3 shows the elastic strap 221 and the first hanging ring 122 in a tied state, and the items on the vehicle chassis 1 are luggage.

[0054] Furthermore, the inner wall of the adjustment groove 21 is provided with a plurality of serrations, and the adjustment portion 22 is also provided with serrations on the surface opposite to the serrations of the adjustment groove 21. The serrations are all located inside the adjustment groove 21, which are not shown in the figure for inconvenience.

[0055] When the adjusting portion 22 is pushed in the direction away from the serrations of the adjusting slot 21, the surfaces of the two serrations do not contact, so that the adjusting portion 22 can move freely along the adjusting slot 21. When the moving position is determined, the serrations of the adjusting portion 22 are fitted with the serrations of the adjusting slot 21, and at the same time, the elastic strap 221 is pulled by the adjusting portion 22 so that the serrations of the adjusting portion 22 cannot be separated from the serrations of the adjusting slot 21. By utilizing the meshing state of the serrations, the position of the adjusting portion 22 is fixed and it cannot continue to move along the adjusting slot 21, thereby avoiding the position displacement of the adjusting portion 22 during the bundling process of the elastic strap 221, which affects the stability of the bundling.

[0056] In some embodiments, reference Figure 4 As shown, the advertising screen 3 is provided with a rotating shaft 31 at both ends along the vertical direction, and the two rotating shafts 31 are pivotally connected to the vehicle chassis 1 and the shared charging box 4, that is, a pivot bearing or a pivot hole can be set at the bottom of the vehicle chassis 1 and the shared charging box 4. If a mounting platform or a mounting seat is set on the top of the support frame 2, a pivot bearing or a pivot hole can also be set at the bottom of the mounting platform or the mounting seat. The advertising screen 3 can be pivotally connected to the pivot bearings or pivot holes on any structure of the vehicle chassis 1 or the industrial charging box, the mounting platform, and the mounting seat through the rotating shafts 31 at the upper and lower ends.

[0057] The advertising screen 3 is pivotally connected via a rotating shaft 31, so that the advertising screen 3 can rotate along the middle of the two support frames 2, thereby opening up the space between the two support frames 2. This is suitable for use when there is too much luggage to be carried by a luggage trolley and there is insufficient space on the chassis 1 and the diagonal support platform 12. By rotating the advertising screen 3, the advertising screen 3 opens up the space on both sides, thereby increasing the space available for placing the luggage trolley, thereby improving the space available for placing the luggage trolley.

[0058] For further reference, Figure 5 As shown, the chassis 1 is provided with a slidable extension frame 16. When the luggage placement space needs to be expanded, the extension frame 16 is pulled out from the bottom of the chassis 1 so that the luggage can be placed on the extension frame 16, further increasing the placement space of the entire luggage trolley.

[0059] The extension frame 16 can be located at the bottom of the vehicle frame 1 or at the top of the vehicle frame 1. Specifically, a slide groove is set at the bottom or top of the vehicle frame 1, and the extension frame 16 is located in the slide groove and can be pulled out or recovered along the slide groove.

[0060] The extension frame 16 is provided with a snap-in groove 161, the inner groove width of the snap-in groove 161 is the same as the thickness of the advertising screen 3, or slightly larger than the inner groove width of the advertising screen 3, and the inner groove of the snap-in groove 161 is L-shaped. After the advertising screen 3 is pivoted, the snap-in groove 161 can be snapped with the bottom of the advertising screen 3, so that the advertising screen 3 cannot continue to rotate, and the space on both sides of the advertising screen 3 can be stably opened, and the normal handling of the luggage cart will not be affected by the rotation of the advertising screen 3 during movement, thereby improving the stability of the luggage expansion space.

[0061] If the extension frame 16 is disposed at the bottom of the vehicle bottom frame 1 , a fitting opening is provided at the front of the vehicle bottom frame 1 for the clamping slot 161 to extend into or extend out of, so as to ensure that the clamping slot 161 will not be interfered with during recovery.

[0062] Among them, a limiting groove 162 is opened on the extension frame 16, and the card slot body 161 can slide along the limiting groove 162. The length of the extension frame 16 extending out of the vehicle bottom frame 1 will not affect the position of the card slot body 161. The card slot body 161 can be moved to a position to be carded with the advertising screen 3 through the limiting groove 162.

[0063] A protrusion 1611 may be provided on the snap-in slot body 161, and a threaded hole is provided on the protrusion 1611, in which a bolt, preferably a butterfly bolt, may be screwed. When the extension frame 16 is continuously pulled out, in order to ensure that the position of the snap-in slot body 161 and the advertising screen 3 is stable and will not move with the extension frame 16, after the extension frame 16 is pulled out to a certain length, the snap-in slot body 161 is moved to the advertising screen 3 through the limit slot 162, and the bolt is tightened so that the bolt is pressed against the limit slot 162 and the protrusion 1611, thereby fixing the snap-in slot body 161 in the position after the limit slot 162 is screwed.

[0064] Further, refer to Figure 6 or Figure 7 As shown, a telescopic slot 24 is provided on the side of the support frame 2 close to the advertising screen 3, and a pulling opening 25 is provided on the side away from the advertising screen 3. The pulling opening 25 is connected to the telescopic slot 24. A clamping portion 26 is provided in the telescopic slot 24, and a pulling portion 27 is provided in the pulling opening 25. The pulling portion 27 is pivotally connected to the clamping portion 26. The clamping portion 26 can adopt a clamping slot 261 body, so a clamping slot 261 is provided on the clamping portion 26. The pulling portion 27 can adopt a pulling rod or a pulling screw. A pivot hole can be provided at one end of the clamping portion 26 close to the pulling opening 25. The pulling portion 27 can be pivotally connected to the clamping portion 26 through the pivot hole and cannot be separated from the pivot hole. At the same time, the pulling portion 27 can pull the clamping portion 26 or push the clamping portion 26 to extend out of the telescopic slot 24 or retract the telescopic slot 24.

[0065] The width of the clamping groove 261 matches the width of the advertising screen 3 , and matching means that the advertising screen 3 can be just embedded or inserted into the clamping groove 261 , so that the clamping portion 26 is clamped with the advertising screen 3 through the clamping groove 261 .

[0066] Specifically, the pulling portion 27 is used to move the clamping portion 26 toward the advertising screen 3. The clamping portion 26 can clamp the side of the advertising screen 3 through the clamping groove 261, so that the advertising screen 3 cannot rotate, so as to achieve the effect of stabilizing the position of the advertising screen 3 when there is no need to expand the luggage placement space. When the advertising screen 3 needs to be rotated, the pulling portion 27 is used to pull the clamping portion 26 toward the telescopic groove 24, so that the clamping portion 26 is received in the telescopic groove 24 and separated from the side of the advertising screen 3. The advertising screen 3 loses the fixing effect of the clamping portion 26 and can be rotated along the pivot point through the rotating shaft 31 to expand the luggage placement space.

[0067] The two support frames 2 are both provided with telescopic slots 24 , clamping portions 26 and pulling portions 27 , so that both sides of the advertising screen 3 are clamped, thereby improving the stability of the advertising screen 3 .

[0068] A rubber pad or a rubber layer may be provided in the clamping groove 261 to prevent the surface of the advertising screen 3 from being damaged.

[0069] Further, refer to Figure 7 As shown, a spring can be arranged in the telescopic groove 24, and the spring contacts the outer wall of the clamping part 26, so that the spring always applies an elastic force to the clamping part 26 in the direction outward of the telescopic groove 24, so that the clamping part 26 can be plugged into the advertising screen 3 under the action of the elastic force to clamp the advertising screen 3. When the pulling part 27 pulls the clamping part 26, the spring is squeezed and the clamping part 26 is separated from the advertising screen 3. When the advertising screen 3 is rotated to the position of the telescopic groove 24, the clamping part 26 is pulled by the pulling part 27 to squeeze the spring. After the pulling part 27 is released, the clamping part 26 is clamped to the advertising screen 3 through the clamping groove 261 under the action of the elastic force of the spring.

[0070] On the other hand, reference Figure 6 As shown, when no spring is provided in the telescopic slot 24, an internal thread is provided in the pulling mouth 25, and an external thread is provided in the pulling portion 27. The pulling portion 27 is screwed to the support frame 2 through the pulling mouth 25. Since the pulling portion 27 and the clamping portion 26 are pivotally connected, when the pulling portion 27 rotates, the clamping portion 26 is limited by the telescopic slot 24 and will not rotate with it. However, the pulling portion 27 is screwed to the pulling mouth 25, so that when the pulling portion 27 rotates, it can extend into or out of the telescopic slot 24 along the pulling mouth 25, and drive the clamping portion 26 to move along the telescopic slot 24, thereby switching the clamping state of the advertising screen 3.

[0071] The screw connection between the pulling opening 25 and the pulling portion 27 can increase the stability of the clamping between the clamping portion 26 and the advertising screen 3, so that the advertising screen 3 can be fixed more firmly when switching positions, thereby reducing the possibility of loosening when moving on a bumpy road.

[0072] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
