Description

Technical Field

[0001] This application relates to the field of material handling technology, and more specifically, to unmanned transport vehicles. Background Technology

[0002] With the development of intelligent technology, driverless transport vehicles have emerged in logistics transportation. By using computers, front infrared rangefinders, front high-definition cameras, GPS navigators, rear infrared rangefinders, rear high-definition cameras, and speed sensors in coordination, driverless transport vehicles can effectively reduce the amount of human resources required for handling goods.

[0003] The prior art publication CN211166649U provides an unmanned transport vehicle, relating to the field of material handling equipment technology. Specifically, it includes a base, with a storage platform fixedly mounted on the upper surface of the base using a bracket. Both sides of the upper surface of the storage platform are fixedly mounted with "U"-shaped frames. Guide wheels for guiding steel wires are fixedly mounted on the top of each frame. Vertically arranged sliding cavities are opened on opposite sides of each frame, and protective covers are provided on the outer sides of each frame. Pulleys corresponding to the sliding cavities are fixedly mounted on the inner walls of both sides of the protective covers, with each pulley sliding in contact with its corresponding cavity. A drive mechanism is fixedly mounted on the mounting plate to drive the protective cover up and down along the sliding cavities on the frames. The drive mechanism allows for free adjustment of the protective cover, enabling it to cover the goods placed on the storage platform, providing protection and preventing goods from falling during transport, thus enhancing the unmanned transport vehicle's ability to protect goods.

[0004] Although the existing technical solutions described above can achieve the relevant beneficial effects through their structure, they still have the following drawbacks:

[0005] The protective cover is used to protect the goods by moving up and down. When loading and unloading goods, the protective cover moves above the frame and exposes the storage platform. When protecting the goods, the protective cover can only protect the goods close to the storage platform. When loading and unloading, the protective cover is above the frame, which makes it difficult to load and unload goods in the space at the top of the frame, making it inconvenient to use.

[0006] Regarding the aforementioned related technologies, the inventor believes that using a vertically movable protective cover to protect goods has several drawbacks. When loading and unloading goods, the protective cover moves above the frame, exposing the storage platform. However, during this process, the protective cover can only protect goods close to the storage platform. Furthermore, when the protective cover is above the frame, it makes it difficult to load and unload goods in the space at the top of the frame, resulting in inconvenience.

[0007] In light of this, we propose an unmanned transport vehicle. Utility Model Content

[0008] 1. Technical problems to be solved

[0009] The purpose of this application is to provide an unmanned transport vehicle that solves the technical problems in the above-mentioned background technology, which uses a protective cover that moves up and down to protect goods. When loading and unloading goods, the protective cover moves above the frame and exposes the storage platform. During protection, the protective cover can only protect the goods near the storage platform. When loading and unloading, the protective cover is above the frame, which makes it difficult to load and unload goods in the space above the frame, resulting in inconvenience. This application achieves the desired technical effect.

[0010] 2. Technical Solution

[0011] The technical solution of this application provides an unmanned transport vehicle, including:

[0012] Vehicle body;

[0013] Side rails: Side rails are fixedly installed on both sides of the top of the vehicle body;

[0014] Support bases are fixedly installed at the bottom of both ends of the side rail;

[0015] Protective doors are rotatably mounted on the support bases;

[0016] An opening and closing mechanism is installed between the top of the protective door and the side railing;

[0017] Telescopic mechanism: The protective door is equipped with a telescopic mechanism, which is connected to the opening and closing mechanism.

[0018] The above solution allows the protective door to be rotated and opened and closed via an opening and closing mechanism. When the protective door is open, the top of the vehicle body is exposed, making it easier to load and unload goods. At the same time, the telescopic mechanism retracts, reducing the space occupied by the protective door after it is opened. During transport, the protective door closes, and the telescopic mechanism extends, thereby shielding and protecting both ends of the vehicle body to prevent goods from falling during transport.

[0019] Optionally, the opening and closing mechanism includes a fixed plate, with fixed plates fixedly installed at the top of both ends of the side rail, and rotating shafts fixedly installed at the top and bottom of the protective door. The rotating shafts rotate through the support base and the fixed plate. The fixed plate has a roller groove, and a toothed ring is fixedly installed on the inner wall of the roller groove. A dual-axis motor is fixedly installed inside the protective door. The top output shaft of the dual-axis motor passes through the protective door and is fixedly sleeved with a rolling gear. The rolling gear is located in the roller groove and meshes with the toothed ring. The bottom output shaft of the dual-axis motor is connected to a telescopic mechanism. The roller groove has an arc-shaped structure, and the axes of the roller groove and the toothed ring coincide with the axis of the rotating shaft. A conductive slip ring is installed between the support base and the rotating shaft at the bottom of the protective door.

[0020] The above scheme uses a dual-axis motor to drive a rolling gear to rotate. As the rolling gear moves along the groove, it rolls along the toothed ring, thereby pushing the protective door to rotate along the shaft, achieving the purpose of opening and closing.

[0021] Optionally, the telescopic mechanism includes a slide groove, the protective door has a slide groove, a drive shaft is rotatably engaged in the slide groove, one end of the drive shaft is sleeved with a meshing bevel gear between it and the output shaft at the bottom of the dual-axis motor, a slide plate is slidably engaged in the slide groove, multiple stops are fixedly installed on the slide plate, the stops slide through the side of the protective door, a rotating cylinder is fixedly sleeved on the drive shaft at the slide groove, the rotating cylinder is provided with a long thread, the slide plate sleeves the rotating cylinder and is threadedly connected to the long thread, the stops on the two protective doors on the same side of the vehicle body are staggered, and anti-collision strips with elastic rubber structure are fixedly installed on the outer walls of both ends of the vehicle body.

[0022] With the above solution, during the opening and closing of the protective door driven by the dual-shaft motor, the transmission shaft is driven to rotate through the linkage of the bevel gear. The transmission shaft drives the rotating drum to rotate. When the protective door is open, the long thread drives the sliding plate to move, so that the stop bar is retracted into the protective door, reducing the volume and facilitating the loading and unloading of goods. When the protective door is closed, the long thread drives the sliding plate to move, so that the stop bar covers and protects the end of the vehicle body, making it convenient to use.

[0023] 3. Beneficial effects

[0024] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0025] 1. This application uses a dual-shaft motor to drive a rolling gear to rotate. As the rolling gear moves along the groove, it rolls along the gear ring, thereby pushing the protective door to rotate along the shaft to achieve the purpose of opening and closing. During the opening and closing process of the protective door driven by the dual-shaft motor, the transmission shaft is driven to rotate through the linkage of the bevel gear. The transmission shaft drives the rotating drum to rotate. When the protective door is open, the long thread drives the sliding plate to move, so that the stop bar is retracted into the protective door, reducing the volume and facilitating the loading and unloading of goods. When the protective door is closed, the long thread drives the sliding plate to move, so that the stop bar covers and protects the end of the vehicle body, making it convenient to use.

The opening and closing mechanism 5 can drive the protective doors 4 to rotate and open and close. When the protective doors 4 are open, the top of the vehicle body 1 is exposed, which facilitates loading and unloading of goods. At this time, the telescopic mechanism 6 retracts, reducing the space occupied by the protective doors 4 after they are opened. During transport, the protective doors 4 are closed, and the telescopic mechanism 6 extends, thereby shielding and protecting both ends of the vehicle body 1 to prevent goods from falling during transport.

A conductive slip ring is installed between the support base 3 and the rotating shaft 52 at the bottom of the protective door 4. The dual-axis motor 53 drives the rolling gear 54 to rotate. When the rolling gear 54 moves along the groove 55, it rolls along the toothed ring 56, thereby pushing the protective door 4 to rotate along the rotating shaft 52 to achieve the purpose of opening and closing.

[0033] Reference Figure 2 and Figure 3The telescopic mechanism 6 includes a slide groove 61. The protective door 4 has a slide groove 61. A drive shaft 62 is rotatably engaged within the slide groove 61.

The levers 67 on the protective doors 4 are interlocked. Both ends of the vehicle body 1 are fixedly installed with anti-collision strips 7 of elastic rubber structure. During the opening and closing of the protective doors 4 driven by the dual-shaft motor 53, the transmission shaft 62 is driven to rotate through the bevel gear 63. The transmission shaft 62 drives the rotating drum 64 to rotate. When the protective doors 4 are open, the long thread 66 drives the sliding plate 65 to move, so that the levers 67 are retracted into the protective doors 4, reducing the volume and facilitating the loading and unloading of goods. When the protective doors 4 are closed, the long thread 66 drives the sliding plate 65 to move, so that the levers 67 cover and protect the ends of the vehicle body 1, making it convenient to use.

[0035] Working principle: The dual-shaft motor 53 drives the rolling gear 54 to rotate. When the rolling gear 54 moves along the groove 55, it rolls along the toothed ring 56, thereby pushing the protective door 4 to rotate along the rotating shaft 52 to achieve the purpose of opening and closing. During the opening and closing process of the protective door 4 driven by the dual-shaft motor 53, the transmission shaft 62 is driven to rotate through the bevel gear 63. The transmission shaft 62 drives the rotating drum 64 to rotate. When the protective door 4 is open, the long thread 66 drives the sliding plate 65 to move, so that the stop lever 67 is retracted into the protective door 4, reducing the volume and facilitating the loading and unloading of goods. When the protective door 4 is closed, the long thread 66 drives the sliding plate 65 to move, so that the stop lever 67 covers and protects the end of the vehicle body 1, making it convenient to use.
