[0047] The present invention will be described in more detail below with reference to the accompanying drawings. It should be noted that the description of the present invention with reference to the accompanying drawings is merely illustrative and non-limiting. Various embodiments can be combined with each other to form other embodiments not shown in the following description.

[0048] A movable platform is a mobile carrier used for transportation, including but not limited to automated guided vehicles, shuttles, and other similar products. A loading platform is provided on the movable platform to serve as a docking device for materials. The surface of the loading platform used to carry materials is called the loading surface, and the loading area is the size of the loading surface.

[0049] See also Figure 1-11 The present invention relates to a movable platform with a variable bearing area, comprising:

[0050] Movable platform 1;

[0051] An adjusting module 2, wherein the adjusting module 2 is installed on the movable platform 1;

[0052] At least two carrier sections 3 are installed on the adjustment module 2; the carrier sections 3 are combined to form part or all of the carrying platform;

[0053] The adjustment module 2 can adjust the distance between the carrier sections 3 to adjust the bearing area of the bearing platform.

[0054] The regulating module 2 described in the present invention can be, but is not limited to, driven by a motor, a screw, or a gear.

[0055] The adjustment module 2 is used to adjust the distance between the carrier sections 3, which can be adjusted to move some of the carrier sections 3 or all of the carrier sections 3 at the same time. The carrier sections 3 can be adjusted to move in one direction or in multiple directions.

[0056] The carrier section 3 has a bearing surface, and the bearing surfaces of the carrier sections 3 are combined to form the bearing surface of the bearing platform. The bearing surfaces of the carrier sections 3 can be spliced together or not in contact with each other.

[0057] More specifically, when the carrier section 3 is adjusted away from the center of the movable platform 1, it extends beyond the edge of the movable platform 1. This has the advantage that when the movable platform 1 is empty, its size is small, making movement and shuttle more flexible. When the movable platform 1 needs to be loaded, the carrier section 3 extends outward toward the edge of the movable platform 1, increasing the load-bearing area and allowing it to carry materials that are much larger than the size of the movable platform 1 itself.

[0058] The present invention solves the problem that the carrier form of the backpack-type movable platform is relatively fixed, and more handling times are required when the materials to be transported are large in size.

[0059] Preferably, the movable platform includes at least three carrier sections, and the adjustment module can adjust the spacing between the carrier sections in at least two different directions. By adjusting the positions of the individual carrier sections, the forces applied can be balanced and distributed, maintaining a stable material load during movement of the movable platform without the need for a spacer device.

[0060] Example 1:

[0061] In a preferred embodiment, the movable platform 1 is in the shape of a cuboid and is provided with wheels on a side of the movable platform 1 close to the ground, so that the movable platform 1 can move freely on the ground.

[0063] The first adjustment component 201 is fixedly arranged on the movable platform 1 along the first direction.

[0064] The second adjustment component 202 is arranged on the first adjustment component 201 along the second direction.

[0065] The second adjustment component 202 can move relative to the movable platform 1 along the first adjustment component 201; the carrier section 3 can move relative to the first adjustment component 201 along a second direction; the first direction and the second direction are arranged to intersect.

[0066] like Figure 1 As shown, its length direction is consistent with the second direction, and its width direction is consistent with the first direction.

[0067] As shown in the figure, the adjustment module 2 includes two groups of first adjustment components 201 symmetrically arranged on the movable platform 1, and two groups of second adjustment components 202 intersectingly arranged on the two groups of first adjustment components 201;

[0068] The two groups of the second adjustment components 202 can move away from or approach each other along the first direction through the two groups of the first adjustment components 201;

[0069] The carrying platform includes four carrier sections 3 , and two carrier sections 3 are installed on each set of the second adjustment components 202 ;

[0070] The carrier sections 3 can be moved away from or closer to each other along the first direction through the first adjustment component 201 , and can be moved away from or closer to each other along the second direction through the second adjustment component 202 .

[0071] In a preferred embodiment, the adjustment module 2 includes a driving device 22, and the driving device 22 is fixedly arranged on the movable platform 1. The output end of the driving device 22 is fixedly connected to the corresponding carrier section 3 to drive the corresponding carrier section 3 to move.

[0072] Preferably, the regulating module 2 includes a driving device 22 and a synchronizing device 23.

[0073] The driving device 22 includes a driving motor 221, and the synchronizing device 23 includes a driving shaft 231, a driven shaft 232, a synchronous belt 233 connecting the driving shaft 231 and the driven shaft 232, and two transmission members 234;

[0074] The output shaft of the driving motor 221 is connected to the driving shaft 231; the driving motor 221, the driving shaft 231, and the driven shaft 232 are installed on the movable platform 1;

[0075] The output shaft of the driving motor 221 is connected to the driving shaft 231;

[0076] The two transmission members 234 are respectively fixed on two opposite sides of the synchronous belt 233 , and the two transmission members 234 are respectively fixedly connected to the two second adjustment assemblies 202 .

[0077] Preferably, the regulating module 2 includes a driving device 22 and a synchronizing device 23.

[0078] The driving device 22 includes a driving motor 221; the synchronizing device 23 includes a driving shaft 231, a driven shaft 232, a synchronous belt 233 connecting the driving shaft 231 and the driven shaft 232, and two transmission members 234; the output shaft of the driving motor 221 is connected to the driving shaft 231; the driving motor 221, the driving shaft 231, and the driven shaft 232 are installed on the movable platform 1;

[0079] The output shaft of the driving motor 221 is connected to the driving shaft 231;

[0080] The two transmission members 234 are respectively fixed to two opposite sides of the synchronous belt 233 , and the two transmission members 234 are respectively fixedly connected to the two carrier sections 3 .

[0081] Each adjustment module 2 includes a drive device 22, which is fixedly mounted on the movable platform 1 and located between the movable platform 1 and the carrier section 3. Each drive device 22 includes a drive motor 221, and each synchronization device 23 includes a driven shaft 232 and a timing belt 233. The drive motor 221, the driving shaft 231, and the driven shaft 232 are all fixedly mounted on the movable platform 1 and located between the movable platform 1 and the carrier section 3. The driving shaft 231 is mounted on the output shaft of the drive motor 221. One end of the timing belt 233 is in driving connection with the driving shaft 231, and the other end is in driving connection with the driven shaft 232.

[0082] To ensure that the synchronous belt 233 can more stably drive the carrier section 3 to slide, the adjustment module 2 further includes a transmission member 234. The transmission member 234 may be square in shape, with one end fixedly connected to the synchronous belt 233 and the other end fixedly connected to the carrier section 3. In practice, the drive motor 221 drives the synchronous belt 233 to move, and the transmission member 234 drives the carrier section 3 to move along with the synchronous belt 233.

[0083] Preferably, the transmission member 234 includes an upper shell 2341 and a lower shell 2342. The upper shell 2341 has a groove formed on a side near the synchronous belt 233, the groove being used to accommodate the synchronous belt 233. The lower shell 2342 has a plurality of protrusions formed on a side near the synchronous belt 233. The protrusions are evenly spaced and sized to match the grooves. Specifically, the synchronous belt 233 is first positioned within the groove, and the lower shell 2342 is then positioned on the upper shell 2341. The protrusions securely secure the synchronous belt 233 within the groove. Fasteners securely connect the upper shell 2341 and the lower shell 2342, thereby securing the transmission member 234 to the synchronous belt 233.

[0084] Taking the carrier subassembly located at the bottom as an example, the two carrier subassemblies 3 are symmetrically arranged along the second direction, the guide rail 211 extends along the first direction, and the carrier subassembly 3 slides back and forth along the first direction. A driving device 22 is provided between the carrier subassembly 3 and the movable platform 1. In order for the two carrier subassemblies 3 to slide symmetrically along the first direction, two transmission members 234 are provided on the synchronous belt 233. One end of one of the transmission members 234 is fixedly provided on the side of the synchronous belt 233 close to the movable platform 1, and the other end is fixedly connected to one of the carrier subassemblies 3. One end of the other transmission member 234 is fixedly provided on the side of the synchronous belt 233 away from the movable platform 1, and the other end is fixedly connected to the other carrier subassembly 3. Since the synchronous belt 233 rotates in a circular motion, when the drive motor 221 rotates, the synchronous belt 233 drives one of the carrier sections 3 to move along the first direction, and the synchronous belt 233 drives the other carrier section 3 to move in the opposite direction of the first direction.

[0085] More preferably, the two carrier subassemblies 3 are provided in conjunction with one drive device 22. That is, the carrier subassembly located at the bottom is provided with one drive device 22, and the synchronous belt 233 provided in conjunction with the drive device 22 is provided along a first direction; the carrier subassembly located at the top is provided with two drive devices 22, and the synchronous belt 233 provided in conjunction with the drive device 22 is provided along a second direction.

The intermediate bracket 4 is fixed to the center line of the movable platform 1 and is arranged along the second direction. The surface of the intermediate bracket 4 away from the movable platform 1 can be part of the load-bearing platform. An anti-slip layer can be provided on the intermediate bracket 4. The intermediate bracket 4 can limit the second adjustment component 202 from sliding toward the other end of the guide rail 211, that is, the two groups of the second adjustment components 202 can only slide back and forth on the guide rails 211 on both sides of the intermediate bracket 4.

[0094] In order to more firmly secure the carrier section 3 to the sliding member 213, the second adjustment assembly 202 further includes a fixing member 214. The fixing member 214 is in the form of an elongated strip, with its length aligned with the second direction. The fixing member 214 is provided with a plurality of screw holes, each of which corresponds one-to-one with the screw holes on the sliding member 213. Fasteners pass through the screw holes and screw holes to secure the fixing member 214 to the sliding member 213.

When the carrier section 3 moves to a specified position, the spring 242 bounces the latch 241 and passes it through the fixing hole 2121, so that the carrier section 3 is fixed at the specified position.

[0099] More preferably, each of the adjustment modules 2 further includes a driving component 25 , and the driving component 25 is used to move the latch 241 out of the fixing hole 2121 .
