[0003] The existing intelligent transport vehicles have at least two intelligent features: first, intelligent load sensing, which "informs" the operator and the sensing probes on both sides that there are goods on the vehicle; second, the cargo fixing structure, which clamps and fixes the goods to prevent them from falling during transportation. However, the existing transport vehicles with load sensing and cargo fixing functions are too complicated in structure, which ultimately leads to high prices and poor practicality. Therefore, the market is in urgent need of a practical storage transport vehicle with load sensing and cargo fixing functions.

[0025] The following descriptions are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention.

[0026] Example: As attached Figure 1 , 2 , 3, 4, 5, 6 and attached Figure 7 As shown, a load sensing and fixing structure for an intelligent warehouse transport vehicle is characterized in that it includes a rectangular groove 1 arranged on the upper surface of the bottom plate 11 of the transport vehicle, a bottom plate 2 arranged in the rectangular groove 1, two side limit plates 3 respectively arranged at the two end positions of the upper surface of the bottom plate 2, an inclined pressure plate unit 4 hinged at the lower end on the upper end surface of one of the side limit plates 3 and used for limiting and fixing above the cargo box 12, a protruding plate unit 5 arranged on the bottom plate 2 and used for receiving the downward pressure of the cargo box 12, a display sensing unit 6 arranged in the side limit plate 3 provided with the inclined pressure plate unit 4 and used for indicating the load status of the transport vehicle, and a driving rope unit 7 arranged in the bottom plate 2 and the side limit plate 3 and used for pulling down and driving the inclined pressure plate unit 4 to open and expose the display sensing unit 6.

[0027] In this embodiment, the protruding plate unit 5 has an initial state of protruding upward, and the force of the protrusion is set to be relatively large, ensuring that a preset number of the cargo boxes 12 in a row, for example, 4, can press down the protruding plate unit 5 only when all are stacked. At this time, the driving rope unit 7 is first pulled downward, and the display sensing unit 6 is lowered, indicating that the transport vehicle is performing normal loading operations. Then the inclined pressure plate unit 4 is pulled to a rotated and folded state. At this time, the inclined pressure plate unit 4 is located below a row of cargo boxes 12, ensuring that the topmost or multiple cargo boxes 12 above can be limited and "pressed" by the inclined pressure plate unit 4 even if they shake up and down during transportation, so as to ensure the effectiveness of the above-mentioned cargo box fixing function.

[0028] Compared with the method of having a fixed inclined plate blocking and limiting on the top, this embodiment has the advantage that all the cargo boxes 12 can be easily placed from top to bottom. That is, if the inclined pressure plate unit 4 is fixed and tilted at a small angle to fix the cargo box, all the cargo boxes must be pushed from the side into the U-shaped structure composed of the bottom plate 2 and the side limiting plate 3, which is relatively laborious. Therefore, triggering the rotating and retracting of the inclined pressure plate unit 4 can ensure the convenience of stacking the cargo boxes from top to bottom.

[0029] The protruding plate unit 5 includes a second rectangular groove 501 arranged on the upper surface of the base plate 2, a fixed plate 502 arranged on the inner bottom surface of the second rectangular groove 501 at a position on one side away from the inclined pressure plate unit 4, a fixed cylinder 503 arranged on the other side of the inner bottom surface of the second rectangular groove 501, a pressure inclined plate 504 whose inclined lower end is hinged on the fixed plate 502 and whose inclined upper end is higher than the upper surface of the transport vehicle bottom plate 11 and located above the fixed cylinder 503, and a protruding column 505 inserted into the fixed cylinder 503 and upwardly supporting the inclined upper end of the pressure inclined plate 504 and used to pull the driving rope unit 7. The protruding plate unit 5 further includes a first fixed pulley 506 disposed in the second rectangular groove 501 and closer to the inclined pressure plate unit 4 than the fixed cylinder 503 and used to bypass the first fixed pulley 506 for installing the driving rope unit 7, and a vertical slot 507 disposed on the fixed cylinder 503 and used for the driving rope unit 7 to extend into and connect to the lower end surface of the protruding column 505. The protruding plate unit 5 further includes a supporting spring 508 disposed in the fixed cylinder 503 and used to push the protruding column 505 upward.

[0030] In this embodiment, after a row of cargo boxes are all stacked, the support spring 508 is compressed to the lowest point, the pressure-bearing inclined plate 504 is at least completely retracted into the rectangular groove 1, the bottom cargo box remains horizontal, and the inclined pressure plate unit 4 is at least rotated and retracted to have a vertical projection overlapping area with the cargo box, so that the upper cargo box 12 has a basically effective limiting and fixing effect when jumping up and down during transportation.

[0031] In addition, after the second-to-last cargo box is stacked, the inclined pressure plate unit 4 is rotated and retracted to a state in which the gap between the inclined pressure plate unit 4 and the side limit plate 3 still ensures that the cargo box can be easily stacked from top to bottom. Therefore, the elastic coefficient of the support spring 508 in this embodiment should be selected in combination with the actual weight of the cargo box to ensure the above-mentioned effect.

[0032] Among them, the first fixed pulley 506 is used to ensure the initial horizontal effect of the rope body in the driving rope unit 7 and ensure the effectiveness of pulling, while the vertical slot 507 is used to effectively convert the lifting action of the protruding column 505 into the pulling action of the rope body in the driving rope unit 7, and finally ensure that the display sensing unit 6 effectively switches to display the loading status and the inclined pressure plate unit 4 effectively presses the cargo box.

[0033] The driving rope unit 7 includes an L-shaped cavity 701 disposed in the bottom plate 2 and having a side opening connected to the second rectangular groove 501, a lower vertical cavity 702 disposed in the side limiting plate 3 and opening upward from the upper opening of the L-shaped cavity 701, a side slot 703 disposed at the upper end of the lower vertical cavity 702 and used to expose the display sensing unit 6, an upper vertical cavity 704 opening upward from the side slot 703 to the upper end surface of the side limiting plate 3, and a connecting rope body 705 passing through the L-shaped cavity 701, the lower vertical cavity 702, the side slot 703 and the upper vertical cavity 704 and used to connect the lower end surface of the protruding column 505 and the inclined pressure plate unit 4. The driving rope unit 7 also includes a second fixed pulley 706 disposed in the L-shaped cavity 701 and used to bypass the installation of the connecting rope body 705.

[0034] In this embodiment, the L-shaped cavity 701, the lower vertical cavity 702, the side groove 703 and the upper vertical cavity 704 are integrally connected to ensure that the connecting rope body 705 can convert the downward displacement of the protruding column 505 into the rotational retraction power of the driving rope unit 7 and the vertical movement force of the display sensing unit 6. Finally, the second fixed pulley 706 is used to fix the connecting rope body 705 which is "L-shaped" as a whole to avoid excessive wear between the connecting rope body 705 and the overall cavity.

[0035] The inclined pressure plate unit 4 includes a vertical plate 401 arranged on the upper end surface of the side limit plate 3, a mounting shaft 402 arranged on the side of the vertical plate 401, an inclined pressure plate 403, a mounting hole 404 arranged at one end of the inclined pressure plate 403 and used to insert the mounting shaft 402, and a torsion spring 405 sleeved on the mounting shaft 402 and used to drive the inclined pressure plate 403 to rotate and open upward in the mounting hole 404. The upper end of the connecting rope body 705 is connected to a side position of the inclined pressure plate 403 close to the mounting hole 404.

[0036] In this embodiment, the torsion spring 405 is arranged in accordance with the prior art, with the aim of making the inclined pressure plate 403 have an initial rotational opening force, thereby ensuring that each cargo box can be relatively easily stacked downward between the two side limit plates 3. Finally, the fixing point of the connecting rope body 705 on the inclined pressure plate 403 is very close to the mounting hole 404, so that the connecting rope body 705 pulls the inclined pressure plate 403 to rotate and close in a manner similar to a "labor-intensive lever", thereby ensuring that a small downward pulling distance of the connecting rope body 705 can be converted into a relatively large rotation angle of the inclined pressure plate 403, thereby ensuring the effective limiting and fixing effect of the inclined pressure plate 403 on the cargo box.

[0037] The display sensing unit 6 includes a receiving groove 601 which is opened upward from the top surface of the side groove 703 and communicates with the upper vertical cavity 704, and a display colored plate 602 which is arranged in the receiving groove 601 and the upper and lower sides are respectively arranged at the two ends of the cut end of the connecting rope body 705. The display sensing unit 6 also includes a reflection plate 603 which is arranged on the side of the display colored plate 602 and is used to reflect the rays used for recording the passage of the transport vehicle.

[0038] In this embodiment, the color of the display colored plate 602 is red, which is bright and eye-catching. The warehouse staff can know from a distance which transport vehicle is carrying goods normally, and the material of the reflective plate 603 is an existing mirror reflective plate or other radio wave reflective plate, which ensures that the existing, for example, activated, infrared generator can receive the emitted light and light waves when the reflective plate 603 passes by, and ensures that the generator can transmit the status of the vehicle carrying goods normally to the control center, so that the information whether all transport vehicles are carrying goods normally can be simply, quickly and accurately known.

[0039] The number of the rectangular grooves 1 on the upper surface of the transport vehicle bottom plate 11 is 2-3.

[0040] In this embodiment, the rectangular groove 1, the bottom plate 2, the side limit plate 3, the inclined pressure plate unit 4, the protruding plate unit 5, the display sensing unit 6 and the driving rope unit 7 constitute a complete set of load sensing and fixing structures. The multiple sets of the load sensing and fixing structures work independently without affecting each other. Therefore, 2-3 rectangular grooves 1 can be set, that is, 2-3 sets of the load sensing and fixing structures.

[0041] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various modifications can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the present invention. These are all non-creative modifications and are protected by patent law as long as they are within the scope of the claims of the present invention.
