This is particularly true in manufacturing sectors such as automotive, logistics, and photovoltaics, where the concept of unmanned factory production has become a mainstream trend. Turnover vehicles, as a form of material transport, are lightweight, flexible, widely applicable, and cost-effective, making them widely used in all aspects of industrial production. With the continuous investment and development of companies in the concept of unmanned factory production, especially the introduction of automated guided vehicles (AGVs) to transport materials, turnover vehicles that can be adapted for AGV use have become a new development direction in turnover vehicle technology.

[0003] Traditional non-powered trolleys lack their own power source and typically display material information via nameplates or work orders. Material updates require manual replacement and are unable to automatically display detailed information such as the work order. Traditional powered trolleys, on the other hand, typically display material information via CTR, LCD, or LED displays, all of which require power from the AGV battery pack. This increases the AGV's power consumption, resulting in increased charging frequency and reduced availability. Summary of the Invention

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0029] Reference Figure 1-Figure 5 As shown, the present invention discloses an unmanned transport turnover vehicle, comprising a vehicle frame 10, casters 13, and an electronic ink screen 11. The vehicle frame 10 is provided with a loading port and a unloading port, which are symmetrically arranged relative to the vehicle frame 10. The electronic ink screen 11 is also provided on the vehicle frame 10. A chassis 12 is provided at the bottom of the vehicle frame 10, which interfaces with a power mechanism 30. The power mechanism is an automatic driving mechanism, such as an AGV.

[0030] Since the present invention is provided with a chassis 12 docked with the power mechanism 30, it can be directly docked with the power mechanism 30 for use, and the transfer process is automatically completed with high efficiency, without the need for manual participation, thus freeing up logistics personnel.

[0031] The electronic ink screen 11 with a display function of the present invention can dynamically display and update various material information and work order information, does not require additional power supply, is easy to use, and is inexpensive. The electronic ink screen 11 uses NFC near-field communication to realize dynamic input and update of display information. The electronic ink screen 11 is configured to display various types of information of unmanned transport turnover vehicles, such as: information about the materials carried, the direction of material flow, and work order details. The user or the AGV dispatching system sends the above information to the power mechanism 30, such as the AGV, through a wireless network. The AGV automatically transmits or updates the information to the electronic ink screen 11 through NFC near-field communication. In addition, the user can also directly write and input display information through a handheld NFC client.

[0032] Since the loading and unloading ports are symmetrically arranged relative to the vehicle frame 10, the turnover vehicle can achieve a first-in-first-out (FIFO) of materials, thus resolving the drawback that powered turnover vehicles cannot achieve FIFO. In the present invention, the turnover vehicle is provided with freely movable casters 13, which can be used in conjunction with the power mechanism 30 or manually propelled. It has strong fault tolerance and can be manually propelled even in the event of a malfunction, thereby ensuring normal production in the workshop.

[0033] like Figure 4 As shown, a limit plate 60 is provided on the lower side of the chassis 12 so that the power mechanism 30 and the vehicle body frame 10 move synchronously. There can be four limit plates 60. When the power mechanism 30 moves between the limit plates 60, the limit plates 60 can prevent relative sliding between the upper surface of the power mechanism 30 and the unmanned transport turnover vehicle. An identification area 121 is provided at the bottom of the chassis 12. The identification area 121 is provided toward the power mechanism 30. The identification area 121 is provided with a QR code or an RFID card for marking the number of the unmanned transport turnover vehicle. The power mechanism 30 automatically identifies the QR code or RFID card information on the identification area 121 through its own camera or RFID.

[0034] like Figure 1 and Figure 2 As shown, a multi-layered loading area 20 is provided on the vehicle frame 10. This multi-layered loading area 20 facilitates the loading of multiple items. At least one horizontal conveyor assembly 40 is provided on the loading area 20, located between the loading and unloading ports. This horizontal conveyor assembly 40 facilitates the loading and unloading of items.

[0035] The horizontal conveyor assembly 40 includes a first gear 44, which meshes with a second gear of the external automated equipment to enable the horizontal conveyor assembly 40 to carry materials. The external automated equipment has a second gear, which in turn has a drive source that drives the second gear to rotate. The turnover vehicle of the present invention is an unpowered structure. By docking the first gear 44 of the turnover vehicle of the present invention with the second gear of the external automated equipment, the second gear can be rotated, thereby achieving movement of the horizontal conveyor assembly 40. The front and rear end structures of the horizontal conveyor assembly 40 are identical, allowing materials to enter and exit the horizontal conveyor assembly 40 from either side. The height and width of the horizontal conveyor assembly 40 installed on the vehicle frame 10 are configured to match the inlet and outlet ports of the automated equipment. Each horizontal conveyor assembly is symmetrically provided with a first gear 44 at both ends, allowing the front end of the horizontal conveyor assembly 40 to dock with the second gear of the automated equipment, or the rear end to dock with the second gear of the automated equipment, thereby obtaining external power.

[0036] The horizontal conveyor assembly 40 includes a first conveyor belt 41, a second conveyor belt 42, a transmission member 43, a first pulley, and a second pulley. The first conveyor belt 41 and the second conveyor belt 42 are coplanar. The first pulley drives the first conveyor belt 41, while the second pulley drives the second conveyor belt. The first and second pulleys are connected by a transmission member. The first pulley or the second pulley is connected to a first gear 44, which drives the first and second pulleys to rotate synchronously. The first gear 44 enables the first and second conveyor belts 41, 42 to move synchronously. The synchronized movement of the first and second conveyor belts 41, 42 enables material transport.

[0037] like Figure 3-Figure 5 As shown, a blocking assembly for limiting material position is provided between the first conveyor belt 41 and the second conveyor belt 42. The blocking assembly can be automatically triggered and reset. When triggered, the material can pass through the blocking assembly without hindrance. When reset, the material is prevented from passing through the blocking assembly. The horizontal conveyor assembly 40 is provided with a blocking assembly at both the inlet and outlet, thus facilitating material position limiting.

[0038] The blocking assembly includes a blocking member 52. When the external automated equipment loads the turnover vehicle, the blocking member 52 moves downward or tilts to allow the material to flow into the turnover vehicle. A base plate 50 can be provided between the first conveyor belt 41 and the second conveyor belt 42. The blocking assembly may include a pressure rod 51 and a reset spring 53. A groove is provided on the base plate 50. The blocking member 52 is inserted into the groove. The pressure rod 51 is connected to the lower end of the blocking member 52 by a rotating shaft. The spring is provided between the pressure rod 51 and the base plate 50. When the pressure rod 51 is subjected to horizontal pressure, the pressure rod 51 can move horizontally to allow the blocking member 52 to rotate around the pressure rod 51, causing the limit plate 60 to tilt, thereby facilitating the inflow of materials. When the pressure rod 51 is no longer subjected to pressure, the spring resets the pressure rod 51, allowing the blocking member 52 to rotate to a vertical state. In this way, the position of the material can be limited.

[0039] Limiting plates 60 are provided on both sides of the conveying assembly 40. The limiting assembly can facilitate the limiting of the transmission of materials.

[0040] The working principle of the present invention is as follows: the AGV provides the power required for the movement of the unmanned transport vehicle, transfers the unmanned transport vehicle to the desired location, aligns the loading and unloading ports of the unmanned transport vehicle with the automation equipment, and the first gear 44 at one end of the horizontal conveying assembly 40 engages with the end of the automation equipment. At the same time, the blocking assembly at the corresponding end is triggered, and the blocking effect is released. The first gear 44 is connected to the conveyor belt, and the automation equipment provides the power for the synchronous transmission of the horizontal conveying assembly 40 through the first gear 44. When the automation equipment is operating, materials can be directly transferred horizontally between the automation equipment and the horizontal conveying assembly 40. After the transfer is completed, the first gear 44 is disengaged from the automation equipment, and the blocking assembly is reset, the blocking effect is activated, and the material transfer process ends.

[0041] like Figure 7 As shown, when picking up materials, the front end of the unmanned transport turnover vehicle is aligned with the automation equipment, the front end first gear 44 of the horizontal conveying component 40 is engaged with the end of the automation equipment, and materials 5a, 5b, 5c and 5d are transferred to the turnover vehicle in sequence.

[0042] When transferring to the next automated equipment for loading, if the first-in-first-out requirement is followed, the AGV drives the turnover vehicle so that the rear end faces the automated equipment, and the gear at the rear end of the turnover vehicle engages with the gear of the automated equipment, and the material will be transferred to the automated equipment in the order of 5a, 5b, 5c, and 5d; if the first-in-last-out requirement is followed, the AGV drives the turnover vehicle so that the front end gear faces the automated equipment, and the front end gear engages with the second gear of the automated equipment, and the material will be transferred to the automated equipment in the order of 5d, 5c, 5b, and 5a. In this way, the turnover vehicle in the present invention can realize both first-in-first-out and first-in-last-out of materials.

[0043] The beneficial effects of the present invention are:

[0044] 1. The unmanned transport turnover vehicle of the present invention can be directly docked and used in conjunction with AGV. The transfer process is completed automatically with high efficiency, no manual participation is required, and logistics personnel are liberated.
