## Abstract

The embodiments of the present disclosure provide a logistics trolley, including a carrier for carrying a material, a body for supporting the carrier, and wheels disposed below the bottom of the trolley body, wherein the carrier has an extension length in a horizontal direction greater than an extension length of the trolley body in a horizontal direction, the carrier includes a conveying mechanism for conveying the material.

## Claims

### Claim 1

A production line, comprising at least one line body having a height and an extension direction, and at least one logistics trolley, each logistics trolley comprising:
a carrier for carrying a material;
a trolley body for supporting the carrier; and
wheels disposed at the bottom of the trolley body, wherein the carrier has an extension length in a horizontal direction greater than an extension length of the trolley body in a horizontal direction, and wherein the carrier comprises a conveying mechanism for conveying the material;
wherein the logistics trolley is arranged to be movable along the extension direction of the line body, and wherein the carrier of the logistics trolley is configured to be higher than the line body and transport the material in a direction transverse to the extension direction of the line body; and
wherein the production line comprises one line body having one logistics trolley disposed at each of two sides, the carriers of the two logistics trolleys arranged oppositely across the line body of the production line.

### Claim 2 (depends on 1)

The production line according to claim 1, wherein the material remains stationary relative to the carrier of the logistics trolley and spans across the carrier, the two logistics trolleys arranged to move along the line body of the production line to move the material along the extension direction of the line body.

### Claim 3 (depends on 1)

The production line according to claim 1, wherein the conveying mechanism of the carrier of each logistics trolley is configured to move the material on the carrier of the two logistics trolleys in a direction transverse to the extension direction of the line body.

### Claim 4 (depends on 1)

The production line according to claim 1, wherein the conveying mechanism comprises a roller conveying mechanism including a support frame and a plurality of rollers mounted on the support frame.

### Claim 5 (depends on 4)

The production line according to claim 4, wherein the logistics trolley further comprises a drive motor arranged to drive the roller conveying mechanism to convey the material.

### Claim 6 (depends on 1)

The production line according to claim 1, wherein the conveying mechanism comprises a belt conveyor.

### Claim 7 (depends on 1)

The production line according to claim 1, wherein the conveying mechanism includes a linear motor and a guide rail on which the linear motor is mounted.

### Claim 8 (depends on 1)
