DETAILED DESCRIPTION

[0021] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0022] like Figures 1 to 4 As shown, a transfer vehicle 10 of the present application includes: a mobile body 11, on which a docking assembly is provided. After the goods are docked by the docking assembly, the mobile body 11 transfers the goods to a designated location. The docking assembly includes: a support frame 12, on which a plurality of rollers 13 are rotatably mounted. The plurality of rollers 13 are arranged in parallel along a straight line, and the two rollers 13 at both ends of the straight line are electric rollers 14. Through the rolling transmission of the electric rollers 14 and the rollers 13, the goods can be docked above the support frame 12.

[0023] Further, at both ends of the support frame 12, there are provided: a baffle 15 and a driving assembly 17. The driving assembly 17 drives the baffle 15 to move between extending the support frame 12 and retracting the support frame 12. In this way, when the cargo is connected, the baffle 15 can block the cargo from the front and rear ends of the support frame 12 to prevent the cargo from falling from the support frame 12. Photoelectric sensors 16 are respectively provided at both ends and the middle of the support frame 12 to control the driving assembly 17 when the cargo is detected. The photoelectric sensors 16 at both ends and the photoelectric sensor 16 in the middle are both communicatively connected to the driving assembly 17. When the photoelectric sensors 16 at both ends and the photoelectric sensor 16 in the middle simultaneously send the same light detection electrical signal to the driving assembly 17, that is, when the photoelectric sensors 16 at both ends and the photoelectric sensor 16 in the middle detect the cargo, it is determined that the cargo has been connected to the designated position of the support frame 12. At this time, the driving assembly 17 receives the electrical signals of the three photoelectric sensors 16 and starts to drive the baffle 15 to extend out of the support frame 12, thereby shielding the cargo. On the contrary, when one or more of the three photoelectric sensors 16 do not send an electrical signal for detecting goods, the driving assembly 17 drives the baffle 15 to be in a state of being retracted into the support frame 12 .

[0024] Furthermore, the photoelectric sensors 16 at both ends are communicatively connected to the electric roller 14. When the photoelectric sensors 16 at both ends send the same light detection electrical signal to the electric roller 14 at the same time, that is, when the photoelectric sensors 16 at both ends detect the goods at the same time or do not detect the goods at the same time, the electric roller 14 receives the electrical signals of the photoelectric sensors 16 at both ends and stops rotating, thereby saving energy while realizing automatic docking.

[0025] Therefore, the above-mentioned transfer vehicle can automatically control the lifting and lowering of the baffle plate 15 at the appropriate time through the electrical connection between the driving component 17 and the photoelectric sensor 16, that is, when docking goods, the baffle plate 15 is retracted into the support frame 12, and when the goods are docked and transferred, the baffle plate 15 is controlled to extend out of the support frame 12. In this way, the baffle plate 15 can prevent the goods from sliding off the front or rear end of the support frame 12 under the influence of the moving inertia, and the installation during the transfer process is stable, thereby improving the logistics efficiency.

[0026] As a specific embodiment, the driving assembly 17 includes: a mounting frame 171, a driving motor 172 is fixed on the mounting frame 171, a crank 173 is fixed on the motor shaft of the driving motor 172, and the baffle 15 is slidably inserted into the guide slot 1711 formed on the mounting frame 171, and a lifting slot 151 is formed at the lower end of the baffle 15 for inserting the axle pin provided at the end of the crank 173 away from the motor shaft. In this way, when the driving motor 172 receives the same electrical signal sent by the three photoelectric sensors 16 at the same time, it starts to rotate, driving the crank 173 to rotate around the axis. Since the moving direction of the baffle 15 is constrained by the guide slot 1711, the baffle 15 is driven by the axle pin to move upward to a preset position through the guide slot 1711 when the crank 173 rotates, thereby shielding the goods. On the contrary, the driving motor 172 flips and drives the baffle 15 to retract into the support frame 12. The outer sleeve of the shaft pin is provided with a pulley 1731. The pulley 1731 is in contact with the groove wall of the lifting groove 151, so that the smoothness of the lifting and lowering of the baffle 15 can be improved and the mechanical energy consumption can be reduced.

[0027] Furthermore, guide shafts 174 are provided on both sides of the baffle 15, and guide holes 1712 are formed on both sides of the guide groove 1711 of the mounting frame 171 for inserting corresponding guide shafts 174. In this way, the lifting and lowering of the baffle 15 can be stabilized by the two guide shafts 174.

[0028] As a specific implementation, the driving motor 172 is provided with a receiving antenna 1721 for receiving electrical signals, and the photoelectric sensors 16 are electrically connected to the receiving antenna 1721 to improve the effectiveness of simultaneously receiving electrical signals from three photoelectric sensors 16 .

[0029] As a specific implementation, the support frame 12 is also provided with an indicator light 18, which is electrically connected to the photoelectric sensors 16 at both ends and in the middle, so as to indicate the current state of the transfer vehicle 10, that is, the docking state or the transfer state, according to the detection information of the photoelectric sensors 16. When the three photoelectric sensors 16 detect the goods at the same time, the indicator light 18 turns green, indicating that the transfer state has been entered. If any of the three photoelectric sensors 16 does not detect the goods, the indicator light 18 turns red, indicating that it is in the docking state.

[0030] As a specific implementation, two roller switches 19 are also provided on the support frame 12 to respectively control the corresponding electric rollers 14, which can be manually operated to improve the controllability of the connection.

[0031] As a specific implementation, the outer circumference of the motorized rollers at both ends are sleeved with two rubber roller rings 141 for driving the goods, increasing the friction between the motorized rollers and the goods, and improving the effectiveness of the goods docking. Specifically, the diameter of the motorized roller is smaller than the diameter of the roller 13 located between the two motorized rollers 14, and the diameter of the rubber roller ring 141 is larger than the diameter of the roller 13. Then, the two rubber roller rings 141 are respectively located at the two ends of the motorized roller 14, and the driving assembly 17 and the baffle 15 are installed between the two rubber roller rings 141 of the same motorized roller 14, so that the installation space of the docking assembly as a whole can be reduced.

[0032] Furthermore, the difference between the diameter of the rubber roller ring 141 and the diameter of the roller 13 is greater than or equal to 0.4 cm and less than or equal to 0.8 cm, so as to ensure the stability and stability of the rubber roller ring 141 in connecting the goods.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the above embodiments do not limit the utility model in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the utility model.
