The terms "first", "second", "third", etc. are only for the convenience of describing the present technical solution, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first", "second", "third", etc. can explicitly or implicitly include one or more of the features. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0030] In the following description, specific details such as specific system structures and technologies are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details that hinder the description of the present invention.

[0031] Please refer to Figures 1 to 4The present application provides a pallet 30 lifting device for unmanned vehicle transportation, which includes a first lifting assembly 10 and a second lifting assembly 20 arranged at intervals, a placement space for placing the unmanned vehicle is formed between the first lifting assembly 10 and the second lifting assembly 20, and the first lifting assembly 10 and the second lifting assembly 20 have a synchronous lifting speed. Among them, the first lifting assembly 10 includes a first frame 11, a first power member 12 and a first support plate 15, the first frame 11 is arranged on the opposite side of the second lifting assembly 20, and a first rotating rod 13 is arranged in the vertical direction inside the first frame 11, and a first connecting member 14 is connected to the first rotating rod 13 in a transmission manner; the first power member 12 is fixed on the top of the first frame 11, and the power output end of the first power member 12 passes through the top of the first frame 11 and is connected to one end of the first rotating rod 13, which is used to control the rotation of the first rotating rod 13 to drive the first connecting member 14 to move back and forth; one end of the first connecting member 14 is embedded in the first support plate 15.

[0032] Exemplarily, the first lifting assembly 10 and the second lifting assembly 20 are symmetrically arranged at intervals so that a placement space can be formed between the first lifting assembly 10 and the second lifting assembly. When the empty pallet 30 on the unmanned vehicle needs to be transported to the pallet 30 warehouse for storage, the unmanned vehicle with the pallet 30 is placed in the placement space. At this time, the first lifting assembly 10 and the second lifting assembly 20 support the two sides of the unmanned vehicle, and then the empty pallet 30 of the unmanned vehicle is lifted to a suitable height with the cooperation of the first lifting assembly 10 and the second lifting assembly 20, and then pushed into the pallet 30 warehouse for storage, thereby realizing automatic transportation. It should be noted that the structures of the first lifting assembly 10 and the second lifting assembly 20 can be the same or different, and there is no limitation on this.

[0033] It should be noted that the "first power member 12" mentioned above can be a motor, the first rotating rod 13 can be a screw rod, and the first connecting member 14 can be a nut seat. In this way, the motor drives the screw rod to rotate, and since the nut seat and the screw rod are connected by threads, the screw rod can drive the nut seat to rise and fall during the rotation process, and then drive the first support plate 15 to rise and fall, so as to realize the unmanned vehicle equipped with the empty pallet 30.

[0034] Here, it should be noted that the above-mentioned "the first lifting assembly 10 and the second lifting assembly 20 have synchronous lifting speeds" may mean that the difference between the lifting speed of the first lifting assembly 10 and the lifting speed of the second lifting assembly 20 is considered to be the same within a certain preset position. For example: the difference between the lifting speed of the first lifting assembly 10 and the lifting speed of the second lifting assembly 20 is between 0 and 1 m / s. If the lifting speed of the first lifting assembly 10 is 3 m / s, and the lifting speed of the second lifting assembly 20 is 3.5 m / s, then the difference between the lifting speed of the first lifting assembly 10 and the lifting speed of the second lifting assembly 20 is 0.5 m / s, and the lifting speeds of the first lifting assembly 10 and the second lifting assembly 20 can be regarded as the same.

[0035] The pallet 30 lifting device for unmanned vehicle transportation based on the above technical features forms a placement space through the first lifting component 10 and the second lifting component 20 arranged at intervals, and then the unmanned vehicle is used to transfer the empty pallet 30 to the placement space. At this time, the two sides of the empty pallet 30 are respectively supported by the first lifting component 10 and the second lifting component 20, and then the empty pallet 30 is lifted to a suitable height by the first lifting component 10 and the second lifting component 20 at a synchronous lifting speed and pushed into the pallet 30 warehouse for storage, thereby realizing automatic transportation, which effectively solves the problem that the existing low-operation and maintenance cost unmanned vehicle without a fork support structure cannot directly deliver the empty pallet 30 into the pallet 30 warehouse, nor can it directly take away the pallet 30 that has been palletized.

[0036] In a possible implementation, the first lifting assembly 10 further includes a plurality of first sliding rods 16 spaced apart in the first frame 11 , a first sliding sleeve 17 is sleeved on the first sliding rod 16 , and one end of the first sliding sleeve 17 is embedded in the first support plate 15 .

[0037] It should be noted that the “plurality” mentioned above refers to two or more than two, and the number of the first sliding bars 16 can be determined according to actual conditions and is not limited thereto.

[0038] Exemplarily, by arranging a plurality of first sliding rods 16 at intervals in the first frame 11, and sleeved on the sliding rods the first sliding sleeves 17, since the first support plate 15 is connected to the first sliding sleeve 17, the first support plate 15 can have better stability when being driven to be raised or lowered, thereby ensuring that the empty pallet 30 is lifted more smoothly.

[0039] In a possible embodiment, the first support plate 15 is provided with a first mounting hole 70 and two second mounting holes 60 at intervals, the first mounting hole 70 is located between the two second mounting holes 60, and the first connector 14 and the first sleeve 17, one end of which extends toward the first support plate 15, respectively extends into the first mounting hole 70 and the second mounting hole 60 to connect with the first support plate 15. In this way, by providing the first mounting hole 70 and the second mounting hole 60 at intervals on the first support plate 15, and then extending the first connector 14 and the first sleeve 17 into the first mounting hole 70 and the second mounting hole 60 respectively, and then fixing the first connector 14 and the first sleeve 17 by fasteners, so that the first connector 14 and the first sleeve 17 can be fixedly connected to the first support plate 15, the structure is simple and the assembly and disassembly are convenient.

[0040] In a possible implementation, the first support plate 15 includes a first connection portion 152 and a first support portion 151 , the first connection portion 152 is located above the first support portion 151 , and the first connection portion 152 and the first support portion 151 are connected by a vertical portion.

[0041] In a possible embodiment, a plurality of first reinforcing blocks 80 and second reinforcing blocks 90 are further included, wherein the first reinforcing blocks 80 are distributed along the first direction on the surface of the vertical portion facing the second lifting assembly 20, and the surface of the first supporting portion 151 is connected to the first reinforcing blocks 80, and the second reinforcing blocks 90 are distributed along the first direction on the surface of the vertical portion facing away from the second lifting assembly 20, and the first connecting portion 152 is connected to the second reinforcing blocks 90. In this way, the strength between the first supporting portion 151 and the first connecting portion 152 can be effectively enhanced by providing a plurality of first reinforcing blocks 80 and second reinforcing blocks 90, and the risk of the empty pallet 30 falling due to breakage during the process of supporting the empty pallet 30 to rise can be effectively avoided.

[0042] In a possible implementation, the width of the first support portion 151 is between 15 cm and 20 cm. The width of the first support portion 151 is set within the above range in order to provide more area for supporting the empty tray 30 and ensure the stability of lifting.

[0043] In a possible implementation, a first protective plate 40 and a second protective plate are further included, and the first protective plate 40 and the second protective plate are respectively arranged on the front surface and the rear surface of the first frame 11 to cover the interior of the first frame 11. In this way, it is possible to effectively prevent foreign matter from entering the first frame 11 and sticking to the first rotating rod 13 and the first sliding rod 16, thereby affecting the smooth lifting of the first support plate 15.

[0044] In a possible implementation manner, the structure of the second lifting assembly 20 is the same as that of the first lifting assembly 10 .

[0045] In a possible implementation manner, a control box 50 is further included. The control box 50 is fixed on the top of the first frame 11 and is used to control the lifting of the first lifting assembly 10 and the second lifting assembly 20 .

[0046] It can be understood that the above embodiments only express the preferred implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the utility model. It should be pointed out that, for ordinary technicians in this field, without departing from the concept of the utility model, the above-mentioned technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the utility model. Therefore, all equivalent changes and modifications made to the scope of the claims of the utility model should belong to the scope covered by the claims of the utility model.
