[0025] 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.
[0026] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0027] This application provides a high-value consumables logistics robot. The robot has a housing 1 for storing high-value consumables. A drive chassis 3, which moves the housing 1, is located at the bottom of the housing 1. The drive chassis 3 specifically includes a chassis frame 31 and a chassis cover 32. The chassis cover 32 is located on the outer periphery of the chassis frame 31 and protects the chassis frame 31 and the components mounted thereon. Drive wheels 2 are located on both side walls of the chassis frame 31, providing power to the drive chassis 3. A laser sensor 5 is located on each side of the drive wheel 2. Several ultrasonic sensors 6 are evenly distributed on opposite side walls of the chassis cover 32. The laser sensors 5 and ultrasonic sensors 6 can emit laser signals and ultrasonic signals to the front and rear sides of the drive chassis 3. Both the laser sensor 5 and the ultrasonic sensor 6 are electrically connected to the first electronic controller 4, which is mounted on the chassis frame 31. The first electronic controller 4 receives road condition information from the laser sensor 5 and the ultrasonic sensor 6, and controls the drive wheels 2 to avoid obstacles or stop moving. In addition, a camera 7 is also provided on the side wall of the chassis cover 32. The camera 7 can capture the road conditions in front of the drive chassis 3 and feed the road condition information back to the first electronic controller 4. The first electronic controller 4 uses the camera 7, the ultrasonic sensor 6 and the laser sensor 5 to detect the road conditions in a coordinated manner, and accurately and stably controls the operation of the high-value consumables logistics robot. Furthermore, an operation panel 8 is provided at the end of the housing 1 away from the drive chassis 3. The operator can issue commands such as running, picking up goods or stopping to the high-value consumables logistics robot through the operation panel 8.
[0028] Please refer to the instruction manual appendix. Figure 2 The chassis frame 31 is a rectangular frame, with rectangular mounting cavities 10 protruding upwards at the four apex corners of the chassis frame 31. Universal wheels 9 are installed inside the mounting cavities 10, each consisting of a wheel body and a connecting frame. The connecting frame is rotatably connected to the top of the mounting cavity 10 and is perpendicular to the top of the mounting cavity 10. The connecting frame is connected to the wheel body, and the rotation axis of the wheel body is perpendicular to the direction of the connecting frame. That is, while the connecting frame drives the wheel body to rotate, the wheel body can also rotate around its own axis. Furthermore, drive wheels 2 are located between the two mounting cavities 10, and the two drive wheels 2 rotate independently. Each drive wheel 2 is connected to a motor. The turning and steering of the high-value consumables logistics robot can be achieved through different speeds and directions of each drive wheel 2. Simultaneously, the universal wheels 9 located on both sides of the drive wheels 2 can support the smooth displacement of the drive chassis 3 and prevent the high-value consumables logistics robot from tipping over due to inertia when the drive chassis 3 turns.
[0029] Please refer to the instruction manual appendix. Figure 2 With appendix Figure 3 Two laser sensors 5 are respectively located on both sides of the drive wheel 2. Each laser sensor 5 is connected to the side of the mounting cavity 10 away from the universal wheel 9 via a mounting plate, and the two mounting cavities 10 are located on the diagonal of the chassis frame 31. A through hole is provided on the end face of the chassis cover 32, through which the laser sensors 5 can pass through the chassis cover 32 and extend to the outside of the drive chassis 3, so that the laser sensors 5 can emit laser signals to the outside. It should be noted that the signal emission directions of the two laser sensors 5 are opposite, that is, the laser sensors 5 can detect whether there are obstacles on the front and rear sides of the drive chassis 3. Furthermore, two ultrasonic sensors 6 are provided on each of the two side walls of the chassis cover 32 parallel to the rotation axis of the drive wheel 2. The ultrasonic sensors 6 are symmetrically distributed at both ends of the side walls of the chassis cover 32, and the direction of the signal emitted by the ultrasonic sensors 6 is always opposite to the movement of the drive chassis 3. With parallel orientation, the ultrasonic sensors 6 can detect whether there are obstacles on the front and rear sides of the drive chassis 3 in real time. There is sufficient spacing between the ultrasonic sensors 6 on the same side to avoid excessive overlap of the detection range of the ultrasonic sensors 6 and improve the reliability of the detection function of the ultrasonic sensors 6. In addition, a camera 7 is also provided on the outer wall of the chassis cover 32. The camera 7 is located on the edge of the drive chassis 3 near the box 1 and is located between the ultrasonic sensors 6 to ensure that the camera 7 can always capture the road conditions in front of the high-value consumables logistics robot and has a sufficient shooting range. A first electronic controller 4 is provided on the chassis frame 31. The first electronic controller 4 is electrically connected to the camera 7, ultrasonic sensors 6 and laser sensors 5 respectively. The first electronic controller 4 receives the road condition information fed back by the above components and controls the drive wheels 2 to perform obstacle avoidance or emergency stop operations.
[0030] Please continue to refer to the instruction manual appendix. Figure 2 Each mounting cavity 10 has a boss 11 at the end opposite to the caster wheel 9. Two parallel support beams 12 are connected between the bosses 11. Each support beam 12 is arranged along the movement direction of the drive chassis 3 and is used to connect the housing 1. Preferably, the support beams 12 and the housing 1 are connected by welding. A battery 17 is provided on the chassis frame 31 between the support beams 12. The battery 17 is electrically connected to electronic components such as the drive wheel 2, laser sensor 5, ultrasonic sensor 6, and camera 7. The battery 17 provides power to the above components.
[0031] Please refer to the instruction manual appendix. Figure 3 A door is provided on the side wall of the box body 1, and a latch 15 is provided on the inner edge of the door. Correspondingly, an electronic lock core 16 is provided on the side wall of the box body 1, which can cooperate with the latch 15. The electronic lock core 16 is electrically connected to the battery 17. Several limiting grooves are evenly distributed on the inner wall of the box body 1 along the height direction of the box body 1. A hook 14 is connected to the top corner of each partition 13. The hook 14 is snapped into the limiting groove to fix the partition 13 in the inner cavity of the box body 1. By changing the snapping position of the hook 14, the spacing between each partition 13 can be changed. Users can adjust it according to the size of the high-value consumables stored to ensure that the storage space in the box body 1 is used to the fullest extent.
[0032] The two sides of the housing 1 perpendicular to the supporting beam 12 have a certain height difference, and the side wall closer to the camera 7 is lower than the other side wall. A top plate 21 is provided at the end of the housing 1 away from the drive chassis 3. The top plate 21 is parallel to each supporting beam. A bent portion is provided on the edge of the top plate 21 near the lower side, fitting snugly against the top of the lower side wall. A fixing cover 22 is provided around the outer side of the area where the top plate 21 fits against the side wall of the housing, fixing the top plate 21 to the side wall of the housing. It should be noted that the operation panel 8 is located on the bent portion of the top plate 21. The operation panel 8 includes a touch screen 81, a card reader 82, a power switch 83, and an emergency stop switch 84. A receiving cavity is provided between the top plate 21 and the housing 1. The container is equipped with a second electronic controller 18, which is electrically connected to the electronic lock cylinder 16. The touch screen 81 is also electrically connected to the second electronic controller 18. Users can enter a password through the touch screen 81 to control the electronic lock cylinder 16 to pop out the latch 15 and open the door. In addition, the card reader 82 is connected to the second electronic controller 18. Users can place their authentication card in the card reader 82, which will identify the identity information. After verifying the information, the second electronic controller 18 will control the electronic lock cylinder 16 to pop out the latch 15 and open the door. The emergency stop switch 84 is electrically connected to the drive wheel 2. Users can press the emergency stop button to lock the drive wheel 2 and achieve an emergency stop. The power switch 83 is directly connected to the battery 17 and controls the start and stop of the high-value consumables logistics robot.
[0033] Preferably, the size of the accommodating cavity is larger than the size of the second electronic controller 18, that is, the outer periphery of the second electronic controller 18 has space allowance, so that after the second electronic controller 18 fails, the maintenance personnel have enough space to put in the maintenance tools, which facilitates the subsequent maintenance work.
[0034] In addition, a first charging port 19 and a second charging port are provided on the side wall of the drive chassis 3. The first charging port 19 is connected to the battery 17 and can be connected to an external charging pile to charge the battery 17. The second charging port 20 is also connected to the battery 17. The operator can manually insert a wire into the second charging port 20 to charge the power supply 17.
[0035] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.
[0036] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
