Abstract
Description
Technical Field
[0001] This utility model relates to the field of AGV anti-tipping technology, specifically an AGV trolley anti-tipping mechanism. Background Technology
[0002] Existing devices, when tilted, can cause the AGV to tip over if the tilt angle is too large. Furthermore, when goods are piled on top of the AGV, the risk of tipping over is even greater once the AGV tilts because the goods tilt simultaneously. Therefore, the AGV needs to provide timely emergency support when it tilts to prevent tipping over, and simultaneously trigger an audible alarm mechanism when tilting occurs. Thus, an AGV anti-tipping mechanism is needed to solve the above problems. Utility Model Content

[0021] 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.
[0022] Please see Figure 1-5 An AGV (Automated Guided Vehicle) anti-tipping mechanism includes: a vehicle body 1; a front panel 2 on the outer wall of the vehicle body 1; a visual zone 3 on the outer wall of the front panel 2; a storage platform 4 on the top of the vehicle body 1; an operation screen 5 on the outer wall of the vehicle body 1; an audible and visual alarm 6 on the outer wall of the vehicle body 1; rollers 7 movably connected to the inner wall of the vehicle body 1; a telescopic motor 8 installed in the inner cavity of the vehicle body 1; a telescopic cylinder 9 connected to the outer wall of the telescopic motor 8; a connecting rod 10 connected to the bottom of the telescopic cylinder 9; and a ground support rod 11 connected to the outer wall of the connecting rod 10. A pressure sensor 12 is installed on the inner wall of the connecting rod 10. A cavity 13 is opened in the inner cavity of the vehicle body 1. A fixed slide 14 is connected to the inner wall of the vehicle body 1. An inner groove 15 is opened on the outer wall of the fixed slide 14. A slider 16 is movably sleeved on the outer wall of the fixed slide 14. An electrode plate 17 is connected to the outer wall of the slider 16. An extension rod 18 is fixedly connected to the inner wall of the vehicle body 1. An electrode plate 19 is connected to the outer wall of the extension rod 18. A return spring 20 is connected to the inner wall of the vehicle body 1. A door 21 is movably connected to the inner wall of the vehicle body 1.
[0023] The visual area 3 is located on the right side of the device, and the inner cavity of the visual area 3 is equipped with a front-facing binocular camera and a 3D LiDAR. By setting the visual area 3 on the right side of the device, the visual area 3 on the front side of the device uses the front-facing binocular camera and 3D LiDAR to construct a three-dimensional model of the environment and identify the ground in advance, so that the device keeps the visual area 3 facing one side.
[0024] The device includes two audible and visual alarms 6, which are symmetrically arranged on both sides of the device. The two audible and visual alarms 6 will flash strongly on both sides of the device and be triggered under specific circumstances, so that staff can understand some of the device's status through the audible and visual alarms 6 on both sides.
[0025] The telescopic motor 8 has a telescopic cylinder 9 connected to its power output end. The telescopic cylinder 9 is connected to the ground support rod 11 via a connecting rod 10. When the telescopic motor 8 outputs telescopic power, the telescopic cylinder 9 enters the telescopic state. The telescopic cylinder 9 synchronously drives the connecting rod 10 to raise and lower the height, thereby controlling the connecting rod 10 and the ground support rod 11.
[0026] The device has four pressure sensors 12, which are arranged symmetrically in pairs inside the connecting rod 10. The four pressure sensors 12 are positioned on both sides of the two connecting rods 10. When the connecting rod 10 and the ground support rod 11 are in contact with the ground at a certain point, the pressure sensors 12 can detect the pressure magnitude at the same time.
[0027] The bottom of the slider 16 is provided with a protrusion, and the outer wall of the protrusion is adapted to the size of the inner wall of the inner groove 15. The bottom of the slider 16 on the device is provided with a protrusion, so that when the slider 16 on the device moves left and right on the outer wall of the fixed slide 14, it slides in the inner cavity of the inner groove 15 by means of the protrusion, thereby making the slider 16 on the device slide along the fixed slide 14.
[0028] Among them, electrode plate 17 and electrode plate 19 are set on the same horizontal line, and electrode plate 17 and electrode plate 19 are electrically connected to the audible and visual alarm 6 and the operation panel 5. Because electrode plate 17 and electrode plate 19 are set on the same horizontal line, when the device is not stable, the slider 16 inside the device will slide to the left or right, so that electrode plate 17 on one side will actively approach and contact electrode plate 19, thereby triggering the audible and visual alarm 6 at the corresponding position to sound an alarm when electrode plate 17 and electrode plate 19 on one side of the device come into contact.
[0029] The return spring 20 is located on the outside of the extension rod 18, and the other end of the return spring 20 away from the vehicle body 1 is in contact with the outer wall of the slider 16. Because the return spring 20 is located on the outside of the extension rod 18, the slider 16 on the device will compress the length of the return spring 20 when the device shakes as a whole, thereby compressing the length of the return spring 20. During this process, the electrode plate 17 and the electrode plate 19 collide, and when the device as a whole returns to balance, the return spring 20 pushes the slider 16 back to its original position.
[0030] The working principle is as follows: First, by setting up structures such as electrode plate 17, electrode plate 19, telescopic motor 8, and ground support rod 11, electrode plate 17 on the device collides with electrode plate 19, triggering the telescopic mechanism of telescopic motor 8. The telescopic cylinder 9 carries the connecting rod 10 to the ground for support, so that the connecting rod 10 and ground support rod 11 on one side of the device contact the ground to form temporary support and prevent the trolley from tipping over. Then, by setting up structures such as slider 16, return spring 20, electrode plate 17, audible and visual alarm 6, and operation panel 5, when the device tilts as a whole, the slider 16 inside the device will slide along the outer wall of the fixed slide rail 14. No matter which side it slides to, electrode plate 17 will actively collide with electrode plate 19. The collision between electrode plate 17 and electrode plate 19 triggers the alarm mechanism of audible and visual alarm 6, so that the operator can know the tilt direction through the audible and visual alarm 6 on one side of the device, and then deactivate the alarm mechanism at the subsequent operation panel 5.
[0031] 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.
