Due to the perpendicular arrangement of the second connection portion 512 and the first connection portion 511, the first connection member 51 may be regarded as an "L" shaped connection member. Therefore, the first connecting piece 51 can be detachably connected with the first support frame 21 and the second support frame 22 of the cargo lifting mechanism 20 through the first connecting part 511, and can be detachably connected with the sliding piece 32 through the second connecting part 512, so that the cargo lifting mechanism 20 is connected with the sliding piece 32. The detachable connection means may include, but is not limited to, a bolt, a screw, or other fastening means.

Referring to fig. 8 and 9, the second link 52 includes a third connecting portion 521 and two fourth connecting portions 522, and the third connecting portion 521 is located between the two sliders 32 and is connected to the transfer member 423. The fourth connecting portion 522 is connected to the end of the third connecting portion 521 and is disposed opposite to the two sliders 32, the fourth connecting portion 522 is connected between the second connecting portion 512 and the sliders 32, and the third connecting member 53 is disposed on the third connecting portion 521. Through the arrangement of the third connecting portion 521 and the two fourth connecting portions 522, the cargo lifting mechanism 20, the sliding member 32 and the conveying member 423 can be connected in pairs without affecting the arrangement of the driving assembly 41.

Alternatively, the fourth connecting portion 522 may be located on a side of the second connecting portion 512 away from the sliding member 32, and connected between the second connecting portion 512 and the cargo lifting mechanism 20.

Wherein the first height threshold includes, but is not limited to, the maximum height that the cargo lift mechanism 20 can move on the guide 31. By providing the engaging piece 60 in this way, the height of the cargo lifting mechanism 20 on the guide 31 can be limited to the first height threshold value, so that the cargo lifting mechanism 20 is prevented from being separated from the guide 31 by the driving of the driving mechanism 40.

To detect the height of the load lifting mechanism 20 on the guide 31, as shown with reference to fig. 8 and 9, the truck may further include a first position detecting assembly electrically connected to the driving assembly 41 of the driving mechanism 40 and configured to detect whether the load lifting mechanism 20 is at a first height threshold on the guide 31. Thus, when the first position detecting assembly detects that the cargo lifting mechanism 20 is at the first height threshold on the guide 31, a corresponding signal can be transmitted to the driving assembly 41 so as to change the rotation direction of the transmission assembly 42 (for example, to change the second transmission wheel 424 from the forward rotation to the reverse rotation) through the driving assembly 41, or to control the first transmission wheel 421 and the second transmission wheel 424 to stop rotating, so as to achieve the purpose of limiting the height of the cargo lifting mechanism 20 on the guide 31 to the first height threshold.

For example, the first position sensor 71 may include, but is not limited to, a proximity sensor or a light sensor. The first position sensor 71 is electrically connected to the driving assembly 41 and configured to determine that the cargo lifting mechanism 20 is at the first height threshold on the guide 31 when the first position sensor 71 moves to a position opposite to the engaging member 60, and transmit a position signal to the driving assembly 41 so as to maintain the cargo lifting mechanism 20 at the first height threshold of the guide 31 by changing the rotation direction of the second transmission wheel 424 by the motor 411 in the driving assembly 41 or stopping the rotation of the second transmission wheel 424.

Referring to fig. 9, a cross beam 33 is connected between the two guiding members 31, the cross beam 33 is connected with one end of the guiding member 31 away from the movable base 10, and the first driving wheel 421 is fixed on the cross beam 33 through a fixing seat 331. The engaging member 60 may be fixed on the cross beam 33 at a position opposite to the first position sensor 71, so that when the first position sensor 71 moves to a position opposite to the engaging member 60 along with the cargo lifting mechanism 20, the engaging member 60 can contact with the first position sensor 71 while being engaged with the third connecting portion 521 of the second connecting member 52, or block light of the first position sensor 71, so as to detect the height of the cargo lifting mechanism 20 on the guide 31 by the first position sensor 71, determine that the cargo lifting mechanism 20 is located at the first height threshold of the guide 31, and transmit a position signal to the driving assembly 41.

As shown in fig. 9, the first position detecting assembly further includes a member to be measured 72, and the first position sensor 71 can be fixed on the third connecting portion 521 of the second connecting member 52 through the member to be measured 72, so that not only the fixing of the first position sensor 71 on the second connecting member 52 can be realized through the member to be measured 72, but also the height of the cargo lift mechanism 20 movable on the guide member 31 can be further limited.

Further, in some embodiments, the cart further comprises a second position detection assembly electrically connected to the drive assembly 41 of the drive mechanism 40 and configured to detect whether the cargo lift mechanism 20 is at a second height threshold on the guide 31, the second height threshold being less than the first height threshold. The second height threshold may include, but is not limited to, a minimum height for the cargo lift mechanism 20 to be movable on the guide 31. In this way, by the cooperation of the first position sensor 71 and the second position sensor 73, the maximum and minimum heights of the cargo lifting mechanism 20 that can move on the guide 31 can be defined, so as to enhance the reliability of the movement of the cargo lifting mechanism 20 on the guide 31.

Wherein the second position detecting assembly includes a second position sensor 73. For example, the second position sensor 73 may include, but is not limited to, a proximity sensor or a light sensor. The second position sensor 73 is located in the moving base 10 and opposite to the object to be measured 72 (as shown in fig. 6), so that when the object to be measured 72 moves to a position opposite to the second position sensor 73 along with the cargo lifting mechanism 20, the object to be measured 72 can contact with the second position sensor 73 or block light of the second position sensor 73, so that the second position sensor 73 detects the height of the cargo lifting mechanism 20 on the guide 31, and it is determined that the cargo lifting mechanism 20 is located at the second height threshold of the guide 31.

The first position detecting unit and the second position detecting unit constitute a position detecting unit 70 of the transportation vehicle. According to the design requirements of different trucks, the heights of the first height threshold and the second height threshold on the guide 31 can be adjusted accordingly, and it is only necessary to ensure that the second height threshold of the guide 31 is lower than the first height threshold of the guide 31.

The second connecting member 52 may be located in the driving housing 80, and the first connecting portion 511 of the first connecting member 51 may be inserted into the assembling slot 81 for connecting the cargo lifting mechanism 20. The goods lifting mechanism 20 is disposed perpendicular to the driving housing 80 and exposed outside the driving housing 80, so that the transporting function of the transporting vehicle for goods such as bins on the transporting lines with different heights can be realized by the goods lifting mechanism 20.

Figure 11 illustrates an enlarged view of the truck of figure 10 at D.

In order to prevent dust or other impurities from entering the interior of the truck through the gap between the first connecting member 51 and the groove wall of the assembling groove 81, referring to fig. 11, a first brush 90a is disposed in the assembling groove 81, the first brush 90a is shielded by the assembling groove 81, and the connecting member 50 is inserted into the first brush 90 a.
