Description

Technical Field

[0001] This utility model relates to the field of unmanned transport vehicle technology, specifically to an unmanned emergency management device. Background Technology

[0002] AGV, or Automated Guided Vehicle, also known as driverless transport vehicle, is a transport vehicle equipped with automatic guidance devices (such as electromagnetic, optical, or sensor devices) that can travel along a prescribed path and has safety protection and transfer functions. Its core technology system covers three major areas: navigation guidance, control system, and safety mechanism.

[0003] AGVs achieve multi-dimensional value enhancement, efficiency and cost optimization, and significantly reduce human error rate through automation. A one-time investment replaces long-term labor costs, supports special scenarios such as darkness (film warehouses), radiation (nuclear power plants), and cleanliness (pharmaceutical workshops), and requires only 50% of the minimum aisle width of traditional forklifts. They also support the integration of complex processes and long-distance transportation (>60 meters).

[0004] Driverless transport vehicles are typically equipped with emergency devices to prevent accidents in case of emergencies. These devices usually control the vehicle to brake suddenly. However, to facilitate subsequent cargo handling, driverless transport vehicles often place goods directly on the top platform of the vehicle. During emergency braking, the goods stacked on top of the vehicle may slide off due to inertia, causing damage to the goods and disrupting the transport of other vehicles. The goods will also need to be rearranged afterward. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an unmanned emergency management device that can effectively solve the problems mentioned in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides an unmanned emergency management device, including an unmanned vehicle body. Each of the four corners of the unmanned vehicle body has a movable wheel. A controller and a servo motor are fixed to the top of one end of the unmanned vehicle body. A placement slot is opened at the top of the other end of the unmanned vehicle body. A sleeve plate is fixed to the bottom of the inner wall of the placement slot. A baffle plate is movably fitted onto the outer wall of the sleeve plate. A second spring is fixed to the inner wall of the baffle plate. A telescopic cylinder and a support rod are fixed to one side of the inner wall of the unmanned vehicle body. A transmission rod is hinged to the power output end of the telescopic cylinder. A limit rod is fixed to one side of the top of the transmission rod. A limit hole is opened through the middle of the top of one side of the baffle plate. Slide grooves are opened on both sides of the top of the unmanned vehicle body. A first spring is fixed to one end of the inner wall of the slide groove, and a slider is fixed to one end of the first spring. A pressure sensor is fixed to the bottom of the inner wall of the slide groove.

[0008] Furthermore, two pressure sensors are provided, one in the middle of the slide groove and the other on the inner wall of the slide groove away from the first spring. The bottom of the slider and the top of the two pressure sensors are on the same horizontal plane.

[0009] Furthermore, a cover plate is fixed to the top of the slide, the height of the slider is less than the depth of the slide, and the length of the first spring is equal to the distance between the pressure sensor located in the middle and one end of the slide.

[0010] Furthermore, a rectangular through hole is provided through the middle of one side of the transmission rod, and one end of the support rod is hinged to the middle of the rectangular through hole. The support rod is located at the end of the transmission rod near the telescopic cylinder.

[0011] Furthermore, there are two second springs, which are located on both sides of the middle part of the inner wall of the baffle, and the length of the two second springs is greater than the sum of the height of the sleeve and the baffle.

[0012] Furthermore, the controller is electrically connected to the telescopic cylinder, the controller is electrically connected to the two pressure sensors, and a timer is installed inside the controller.

[0013] Furthermore, a driven gear is rotatably connected to the top of one side of the inner wall of the autonomous vehicle body, and a rotating roller is fixed to one side of the driven gear. There are two driven gears, and a driving gear meshes in the middle of each of the two adjacent driven gears. The power output end of the servo motor is fixed to one of the driving gears.

[0014] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0015] 1. This application determines whether emergency handling is required by using the signal transmission time interval of the controller and two pressure sensors. When it is determined that emergency handling is required, the controller controls the extension cylinder to extend, the limit rod at the top of the transmission rod slides out of the limit hole, and the second spring releases its elastic potential energy, causing the baffle to quickly pop out from inside the sleeve plate. The baffle blocks the goods on the top of the rotating roller, thereby achieving the effect of blocking the transported goods and preventing them from falling in an emergency.

[0016] 2. This application uses a support rod to support the transmission rod. When the telescopic cylinder extends, the bottom end of the transmission rod moves a small distance. The lever principle causes the top end of the transmission rod to move a longer distance, allowing the limiting rod at the top of the transmission rod to slide out of the limiting hole quickly, thereby achieving a faster response speed of the device.

[0017] 3. When it is necessary to unload goods onto a platform with a small height difference from the unmanned vehicle, this application can drive the active gear to rotate via a servo motor, which in turn drives multiple driven gears and rotating rollers to rotate simultaneously, thereby achieving self-unloading of the top goods, thus enabling the vehicle to have unloading capabilities and improving the efficiency of some goods transportation.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0027] This application discloses an unmanned emergency management device, including an unmanned vehicle body 1. Each of the four corners of the unmanned vehicle body 1 has a movable wheel 2. A controller 3 and a servo motor 4 are fixed to the top of one end of the unmanned vehicle body 1. A placement groove 12 is opened at the top of the other end of the unmanned vehicle body 1. A sleeve plate 13 is fixed to the bottom of the inner wall of the placement groove 12. A baffle 14 is movably sleeved on the outer wall of the sleeve plate 13. A second spring 20 is fixed to the inner wall of the baffle 14. A telescopic cylinder 15 and a support rod 16 are fixed to one side of the inner wall of the unmanned vehicle body 1. A transmission rod 17 is hinged to the power output end of the telescopic cylinder 15. A limit rod 18 is fixed to one side of the top of the transmission rod 17. A limit hole 21 is opened through the middle of the top of one side of the baffle 14. Slide grooves 8 are opened on both sides of the top of the unmanned vehicle body 1. A first spring 9 is fixed to one end of the inner wall of the slide groove 8. A slider 10 is fixed to one end of the first spring 9. A pressure sensor 11 is fixed to the bottom of the inner wall of the slide groove 8.

[0028] Reference Appendix Figure 2There are two pressure sensors 11, located in the middle of the slide 8 and at the end of the inner wall of the slide 8 away from the first spring 9, respectively. The bottom of the slider 10 and the top of the two pressure sensors 11 are on the same horizontal plane. A cover plate is fixed to the top of the slide 8. The height of the slider 10 is less than the depth of the slide 8. The length of the first spring 9 is equal to the distance between the pressure sensor 11 in the middle and one end of the slide 8. The cover plate is set to prevent the movement of the slider 10 from being affected when goods are stacked later. When the unmanned vehicle body 1 brakes, the slider 10 slides inside the slide 8. The first spring 9 is a soft spring, and the first spring 9 has little effect on the slider 10 when it moves. When there is no external force, the slider 10 is located on the side of the pressure sensor 11 in the middle. When braking, the slider 10 passes the pressure sensor 11 in the middle first and then passes the pressure sensor 11 at the right end.

[0029] Reference Appendix Figure 4 A rectangular through hole 19 is provided through the middle of one side of the transmission rod 17. One end of the support rod 16 is hinged to the middle of the rectangular through hole 19. The support rod 16 is located at the end of the transmission rod 17 near the telescopic cylinder 15. The support rod 16 supports the transmission rod 17. When the telescopic cylinder 15 extends, the bottom end of the transmission rod 17 moves a small distance. The lever principle causes the top end of the transmission rod 17 to move a longer distance, so that the limiting rod 18 at the top of the transmission rod 17 can slide out quickly from the limiting hole 21.

[0030] Reference Appendix Figure 4 There are two second springs 20, which are located on both sides of the middle part of the inner wall of the baffle 14. The length of the two second springs 20 is greater than the sum of the heights of the sleeve 13 and the baffle 14. The baffle 14 is supported by the two second springs 20. When the limiting rod 18 separates from the limiting hole 21, the second springs 20 release elastic potential energy, causing the baffle 14 to pop out quickly from inside the sleeve 13. The baffle 14 blocks the goods on the top of the rotating roller 7.

[0031] Reference Appendix Figure 1 and 3 The controller 3 is electrically connected to the telescopic cylinder 15 and to two pressure sensors 11. The controller 3 has a timer inside. When the pressure sensor 11 senses pressure, it sends a signal to the controller 3. The timer inside the controller 3 records the signal interval between the two pressure sensors 11. The intervention value of the timer is preset. When the time interval between the received signals from the two pressure sensors 11 is less than the intervention value, the controller 3 controls the telescopic cylinder 15 to extend.

[0032] Reference Appendix Figure 3The unmanned vehicle body 1 has a driven gear 6 rotatably connected to the top of one side of its inner wall. A rotating roller 7 is fixed to one side of the driven gear 6. There are two driven gears 6, and each of the two adjacent driven gears 6 has a driving gear 5 meshing in the middle. The power output end of the servo motor 4 is fixed to one of the driving gears 5. When it is necessary to unload the goods onto a platform with a small height difference from the unmanned vehicle body 1, the servo motor 4 can drive the driving gear 5 to rotate, thereby driving multiple driven gears 6 and rotating roller 7 to rotate simultaneously, so as to realize the self-unloading of the goods on the top.

[0033] The workflow of this utility model is as follows:

[0034] During the movement of goods by the unmanned vehicle body 1, when braking, the slider 10 slides inside the slide groove 8. The first spring 9 is a soft spring, so its influence on the slider 10 is minimal when it moves. When not subjected to external force, the slider 10 is located on the side of the pressure sensor 11 in the middle. When braking, the slider 10 first passes the pressure sensor 11 in the middle and then passes the pressure sensor 11 located at the right end. When the pressure sensor 11 senses pressure, it sends a signal to the controller 3. The timer inside the controller 3 records the signal distance between the two pressure sensors 11. The intervention value of the timer is preset in advance. When the signal interval time of pressure sensor 11 is less than the intervention value, controller 3 controls telescopic cylinder 15 to extend, supporting transmission rod 17 through support rod 16. When telescopic cylinder 15 extends, the bottom end of transmission rod 17 moves a small distance. The lever principle causes the top end of transmission rod 17 to move a longer distance, allowing the limiting rod 18 at the top of transmission rod 17 to slide out of limiting hole 21 quickly. When limiting rod 18 separates from limiting hole 21, second spring 20 releases elastic potential energy, causing baffle 14 to pop out quickly from inside sleeve 13. Baffle 14 blocks the goods on top of rotating roller 7.

[0035] The controller model mentioned above can be FV420.

[0036] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
