The first embodiment is as follows:
referring to fig. 1 and 2, fig. 1 and 2 are schematic structural views of a rotating device for a logistics trolley in different angles, which includes a cargo base 100 and a connection base 200, wherein the cargo base 100 is used for supporting cargo, for example, a tray 110 of the cargo base 100 can be used for placing the cargo, and a first fixing portion 101 is disposed on the top of the cargo base 100. The connection base 200 is used for being fixed with a moving mechanism 210 of the logistics trolley, the connection base 200 is provided with a second fixing part 201, and the first fixing part 101 and the second fixing part 201 are rotatably connected through a rotating shaft 300.
The cargo base 100 and the connection base 200 both include a plate-shaped structure having a thickness, and when the first fixing portion 101 and the second fixing portion 201 are connected by the rotation shaft 300, the cargo base 100 can be relatively rotated with respect to the connection base 200.
The cargo base 100 is provided with a limiting sliding groove 102, the connection base 200 is provided with a positioning pin 202, and the positioning pin 202 is suitable for being inserted into the limiting sliding groove 102, so that the limiting sliding groove 102 can limit the rotation angle of the connection base 200.
Referring to fig. 2, in this embodiment, the limiting chute 102 is an arc-shaped track, two ends of the limiting chute 102 are end points of the track, two ends of the limiting chute 102 are provided with locking openings for limiting the positioning pin 202, and when the positioning pin 202 moves to a certain end point, the positioning pin 202 can stay at the end point to limit the deflection amplitude of the connection base 200. It is understood that the amplitude of the deflection of the linking base 200 is limited, i.e. the angle of rotation of the linking base 200 relative to the cargo base 100 is limited.
In this embodiment, the limiting sliding groove 102 limits the connecting base 200 to swing within a range of plus or minus 95 °.
In other embodiments, the limiting sliding groove 102 limits the connecting base 200 to swing within a range of plus or minus 45 °.
In this embodiment, the position of the positioning pin 202 corresponds to the midpoint of the limiting chute 102, and the movement track of the positioning pin 202 is a partial circumference taking the center of the rotating shaft as the center of the circle and the distance from the center of the rotating shaft to the positioning pin 202 as the radius, or the shape of the limiting chute 102 is a partial circumference taking the center of the rotating shaft as the center of the circle and the distance from the center of the rotating shaft to the positioning pin 202 as the radius.
According to the rotating device for the logistics trolley, the embodiment also provides the logistics trolley which comprises the rotating device and a moving mechanism 210, wherein the moving mechanism 210 is suitable for moving along the logistics track. The movement mechanism 210 described herein includes a connection base 200. An angle sensor (not shown) and a fixer 400 are arranged on the moving mechanism 210, and the angle sensor is used for measuring the rotating state of the moving mechanism 210; the rotating state comprises a first state and a second state; the moving mechanism 210 is in the first state without rotating relative to the connection base 200, and the moving mechanism 210 is in the second state with rotating relative to the connection base 200.
For example, when the moving mechanism 210 moves only on a horizontal rail, or the moving mechanism 210 moves only on a vertical rail, the cargo on the pallet 110 is kept stable by the gravity H, and the moving mechanism 210 does not have an angular deflection with respect to the horizontal plane, that is, the moving mechanism 210 does not rotate with respect to the connection base 200, and the angular sensor measures the moving state of the moving mechanism 210 as the first state.
For example, when the moving mechanism 210 is turned from the horizontal rail of the vertical rail to the left or right, since the cargo base 100 can rotate relatively to the connection base 200 and the cargo on the pallet 110 is acted by the gravity H, the cargo base 100 does not rotate relative to the horizontal plane, only the moving mechanism 210 rotates, that is, the moving mechanism 210 rotates relative to the cargo base 100, and the angle sensor measures the motion state of the moving mechanism 210 as the second state.
In this embodiment, the fastener 400 is activated by the first state of the moving mechanism 210 to limit the relative rotation between the moving mechanism 210 and the cargo bed 100. For example, when the moving mechanism 210 is not angularly deflected relative to the horizontal plane, the retainer 400 operates to limit the relative rotation between the moving mechanism 210 and the cargo bed 100.
In this embodiment, the fixer 400 may include an electromagnet, and a metal may be disposed on the cargo bed 100 at a corresponding position. When the moving mechanism 210 does not deflect at an angle relative to the horizontal plane, the electromagnet works, and the moving mechanism 210 is attracted by magnetic force to limit the relative rotation between the moving mechanism 210 and the cargo base 100, so that the possibility of shaking of the cargo base 100 is reduced when the moving mechanism 210 moves in a horizontal or vertical track, and the safety of the cargo transportation process is improved.
The retainer 400 is closed under the trigger of the second state of the moving mechanism 210, and the relative rotation between the moving mechanism 210 and the cargo bed 100 is released.
For example, when the moving mechanism 210 is angularly deflected with respect to the horizontal plane, the electromagnet is turned off, so that the moving mechanism 210 and the cargo base 100 can rotate relatively, that is, only when the moving mechanism 210 rotates with respect to the cargo base 100, the cargo base 100 does not rotate with respect to the horizontal plane, thereby ensuring the level of the cargo on the pallet 110 during the turning process and ensuring the distribution safety of the cargo during the distribution process.
In this embodiment, the fixing device 400 includes at least two electromagnets, and the electromagnets are symmetrically disposed on two sides of the connection base 200, that is, on two sides of the moving mechanism 210.
In this embodiment, balls are disposed between the cargo base 100 and the moving mechanism 210 to reduce friction between the cargo base 100 and the moving mechanism 210, reduce resistance when the cargo base 100 and the moving mechanism 210 rotate relatively, improve rotation efficiency, and ensure a service life of the logistics trolley. In some embodiments, the cargo bed 100 and the moving mechanism 210 may be further configured with a layer of lubricant oil.
The commodity circulation dolly with rotary device can be applied to track commodity circulation transmission field, and especially medical treatment, takeaway are dispatched, the express delivery is dispatched, the aspect such as machine-building has guaranteed that the commodity circulation dolly is switched into horizontal orbital in-process by vertical track, and the surface that cargo base 100 was used for the bearing goods remains the level all the time to avoid the goods to empty, guaranteed the delivery safety of product.
According to the logistics trolley, the embodiment also provides an unmanned distribution system, and the system comprises the logistics trolley.
The present invention has been described in terms of specific examples, which are provided to aid understanding of the invention and are not intended to be limiting. For a person skilled in the art to which the invention pertains, several simple deductions, modifications or substitutions may be made according to the idea of the invention.
