Description

Technical Field

[0001] This utility model relates to the field of unmanned logistics vehicle technology, specifically to an automatic sensing unmanned logistics vehicle door device. Background Technology

[0002] With the continuous development of vehicle and computer technologies, autonomous driving technology is maturing and has gradually become a research hotspot for many scholars both domestically and internationally. Relying on the collaborative efforts of artificial intelligence, computer vision, radar, monitoring devices, and global positioning systems, computers can automatically and safely operate motor vehicles without any human intervention. However, despite the rapid development of autonomous driving technology, its practical implementation in passenger cars remains limited, with applications only found in some small logistics vehicles.

[0003] Currently, the doors of driverless logistics vehicles are opened manually by logistics personnel. However, since logistics personnel are carrying goods in both hands, they do not have a free hand to open the door. Therefore, logistics personnel need to put down the goods in their hands before they can open the door and store the goods into the vehicle, which leads to low work efficiency. Utility Model Content

A rotating shaft is rotatably mounted inside each support. Sleeves are fixedly mounted on the outer sides of both ends of the rotating shaft. An L-shaped drive arm is fixedly mounted on one side of each sleeve. The other end of the L-shaped drive arm is fixedly mounted to the door panel via a fixing plate. A transmission gear is fixedly mounted in the middle section of the rotating shaft. A drive gear meshes with the side of the transmission gear. The shaft of the drive gear is fixedly mounted to the output end of the motor reducer. The motor reducer is fixedly mounted to the top of the unmanned logistics vehicle body. The motor reducer is a servo reducer with a self-locking output shaft function.

[0006] Preferably, a shaft housing is fitted on the outer side of the rotating shaft, one end of the shaft housing is fixedly installed with the support, and a gear housing is fixedly installed on the other end of the shaft housing.

[0007] Preferably, a travel limit switch is fixedly installed on the top of the unmanned logistics vehicle body and behind the sleeve, and a pressure sensor is embedded on the top of the unmanned logistics vehicle body and below the L-shaped drive arm.

[0009] Preferably, an electronic lock is embedded inside the door panel, and the electronic lock is connected to the PLC controller via signal.

[0010] (III) Beneficial Effects Compared with the prior art, this utility model provides an automatic sensing unmanned logistics vehicle door device, which has the following beneficial effects: 1. The automatic sensing unmanned logistics vehicle door device uses a touch-sensitive switch to transmit a signal to the PLC controller for signal processing. The PLC controller then controls the motor reducer to run, which in turn controls the drive gear to rotate. The drive gear then drives the transmission gear to rotate, which in turn drives the rotating shaft to rotate. The rotating shaft then drives the L-shaped drive arm to rotate, which in turn rotates and opens the door panel, thus achieving the purpose of automatically sensing and opening the door.

[0011] 2.

This process realizes the automatic opening or closing of the door panel, improving work efficiency. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1 The automatic sensing unmanned logistics vehicle door device includes an unmanned logistics vehicle body 1, which is an unmanned logistics vehicle product that is already mature in the market. As it is a known technology, its principle will not be described in detail in this application. Door panels 2 are movably installed on both the front and rear sides of the unmanned logistics vehicle body 1. A sensor switch 3 is embedded in the frame of the unmanned logistics vehicle body 1. The sensor switch 3 is an infrared touch sensor switch. Even without touching it with a finger or elbow, the human body temperature will cause the sensor switch 3 to send an open or close signal. At the same time, depending on the actual situation, the sensor switch 3 can be replaced with a facial recognition camera. When the logistics personnel face the camera, they can also control the door to open automatically. A drive component 4 is set on the top of the unmanned logistics vehicle body 1 to drive the door panels 2 to open or close automatically.

[0016] Please see Figure 2-4 The drive assembly 4 includes three sets of supports 41, with two supports in each set. The three sets of supports 41 are arranged at equal intervals. A rotating shaft 42 is rotatably installed inside the support 41. A sleeve 43 is fixedly installed on the outer side of both ends of the rotating shaft 42. An L-shaped drive arm 44 is fixedly installed on one side of the sleeve 43. The other end of the L-shaped drive arm 44 is fixedly installed to the door panel 2 through a fixing plate 45.

[0017] Please see Figure 2-4 A transmission gear 46 is fixedly installed in the middle section of the rotating shaft 42. A drive gear 47 meshes with the side of the transmission gear 46. The shaft of the drive gear 47 is fixedly installed with the output end of the motor reducer 48. The motor reducer 48 is fixedly installed on the top of the unmanned logistics vehicle body 1. The motor reducer 48 is a servo reducer with a self-locking output shaft function.

[0018] Please see Figure 2-4A shaft housing 49 is fitted on the outside of the rotating shaft 42 to protect the rotating shaft 42; one end of the shaft housing 49 is fixedly installed with the support 41, and the other end of the shaft housing 49 is fixedly installed with a gear housing 410 to protect the gear.

[0019] Please see Figure 2-4 A travel limit switch 411 is fixedly installed on the top of the unmanned logistics vehicle body 1 and behind the sleeve 43 to determine that the motor reducer 48 will stop running after the door panel 2 is rotated open; a pressure sensor is embedded on the top of the unmanned logistics vehicle body 1 and below the L-shaped drive arm 44 to ensure that the motor reducer 48 will stop running after the door panel 2 is rotated closed.

[0020] Please see Figure 2-4 The inductive switch 3, pressure sensor and travel limit switch 411 are all connected to the PLC controller signal. The PLC controller is connected to the motor reducer 48 signal. The PLC controller is also connected to the internal control system of the unmanned logistics vehicle body 1 signal. An electronic lock is embedded inside the door panel 2. The electronic lock is connected to the PLC controller signal.

[0021] Please see Figure 1-4 The inductive switch 3, pressure sensor, travel limit switch 411, PLC controller, motor reducer 48 and electronic lock are all references to existing technologies, which will not be described in detail in this application. When using them, the preferred option can be selected under the premise of meeting the driving conditions.

[0022] Working principle: When in use, the sensor switch 3 is touched by a finger. The sensor switch 3 transmits the signal to the PLC controller for signal processing. The PLC controller then controls the motor reducer 48 to run. The motor reducer 48 controls the drive gear 47 to rotate. The drive gear 47 drives the transmission gear 46 to rotate. The transmission gear 46 drives the rotating shaft 42 to rotate. The rotating shaft 42 drives the L-shaped drive arm 44 to rotate. The L-shaped drive arm 44 then rotates and opens the door panel 2, thereby achieving the purpose of automatically sensing and opening the door.

[0023] When the L-shaped drive arm 44 rotates to the 120° position, that is, the door panel 2 is rotated open by 120°, the L-shaped drive arm 44 is exactly pressing against the travel limit switch 411, and the travel limit switch 411 will stop the motor reducer 48 through the PLC controller. Conversely, when the door panel 2 rotates to close, the L-shaped drive arm 44 presses against the pressure sensor, and the PLC controller stops the motor reducer 48. This process enables the door panel 2 to open or close automatically, improving work efficiency.

[0024] After door panel 2 is closed, the electronic lock automatically locks door panel 2 to the frame of unmanned logistics vehicle body 1. Conversely, the PLC controller can also drive the electronic lock to open automatically, allowing door panel 2 to be opened again.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
