TECHNICAL FIELD

[0001] The present application relates to the technical field of transportation equipment, in particular to an automatic guided vehicle capable of stabilizing load. BACKGROUND

[0002] The automatic guided vehicle is an unmanned transportation tool powered by a battery, which travels along a preset path through navigation devices such as magnetic strips, tracks, lasers or two-dimensional codes. The system is composed of an AGV, a control computer, navigation devices and a charging device, and can realize path planning, task execution and automatic charging. The automatic guided vehicle is now widely used in the logistics industry. The automatic guided vehicle transports goods to the predetermined storage location according to the instructions of the system. In the logistics industry, goods are usually stacked in the cargo box of the automatic guided vehicle for transportation. However, the existing technology does not have a goods loading and fixing structure. When the stacked goods tilt in the cargo box, the overall center of gravity of the guided vehicle will shift, which may cause the guided vehicle to roll over when turning. SUMMARY

[0003] The present application aims to solve the shortcomings in the prior art and proposes an automatic guided vehicle capable of stabilizing load. The fixed mechanism is provided, so that when the goods tilt, the receiving plate tilts synchronously, the receiving plate drives the first gear to rotate, so that under the meshing action of the first gear and the first rack, the first rack drives the inclined block to slide, so that the starting frame moves away from the first rack along the inclined surface of the inclined block, and then the starting frame drives the sliding groove to slide relative to the linkage rod, the two linkage rods drive the two clamping plates to move closer to each other, and the tilted goods stack is clamped and fixed from both sides, which avoids the further tilting of the stacked goods, thereby reducing the overall center of gravity shift trend of the guided vehicle, and further reducing the risk of vehicle rollover when the guided vehicle turns.

[0004] In order to achieve the above object, the present application adopts the following technical scheme: An automatic guided vehicle capable of stabilizing load, comprising a vehicle body, a cargo box is arranged on the top outer wall of the vehicle body, a receiving plate is rotatably inserted on the inner wall of the cargo box through a rotating shaft, a transmission chamber is arranged in the cargo box, a first gear is installed on the rotating shaft of the receiving plate and rotatably inserted in the transmission chamber, a box door is slidably inserted on one side outer wall of the cargo box, a third rack is fixed on the outer wall of the box door and engaged with the first gear, a fixing mechanism is arranged in the cargo box, a balancing mechanism is arranged on the vehicle body, the fixing mechanism comprises a first rack slidably inserted on the bottom of the transmission chamber, the first rack is engaged with the first gear, a pair of symmetrical inclined blocks are welded on the outer wall of the first rack, a starting frame abutting against the inclined blocks is slidably inserted on the inner wall of the bottom of the cargo box, V-shaped grooves are formed on the outer wall of the starting frame, clamping plates are slidably inserted on the inner wall of the cargo box and the box door, a linkage rod is slidably inserted in the groove and welded on the outer wall of each clamping plate, when the box door is moved upward to open the cargo box, the receiving plate drives the goods to tilt toward the side of the box door for unloading, at the same time, the engagement of the first gear and the first rack triggers the fixing mechanism, the clamping plates in the cargo box push the goods to the side of the box door, when the goods pile is tilted due to the shift of the center of gravity, the fixing mechanism drives the clamping plates on both sides to fix the goods.

[0005] Preferably, a second spring is arranged between the outer wall of the starting frame and the inner wall of the cargo box.

[0006] Preferably, a pair of first springs are arranged between the bottom outer wall of the receiving plate and the inner wall of the cargo box and symmetrically distributed on both sides of the first gear.

[0007] Preferably, the balancing mechanism comprises a pair of second racks arranged on the outer walls of both ends of the first rack, a pair of deflection frames are rotatably inserted on the top outer wall of the vehicle body and symmetrically distributed on both sides of the receiving plate through a rotating shaft, a pair of protrusions are arranged on the outer wall of one end of the vehicle body and symmetrically distributed on both sides of the vehicle body.

[0008] Preferably, a second gear is installed on the rotating shaft of each deflection frame and engaged with the second rack.

[0009] Preferably, a slide rod is slidably inserted in each deflection frame, an installation frame is welded on the outer wall of one end of each slide rod away from the vehicle body, an avoidance groove is formed on the outer wall of the first rack, and a trigger rod is slidably inserted in the avoidance groove and welded on the outer wall of each slide rod.

[0010] Preferably, a third spring is arranged between the outer wall of each installation frame and the outer wall of the deflection frame, a universal wheel is rotatably connected to the outer wall of each installation frame, and a protective plate is installed on the outer wall of each installation frame.

[0011] Preferred configuration: The impact is buffered by the balancing mechanism, and the fixing mechanism is triggered by the trigger rod to clamp and fix the goods during the impact. When the stacked goods tilt due to the shift of the center of gravity, the balancing mechanism drives the deflection frame to rotate the mounting frame toward the tilted side of the receiving plate under the meshing action of the second rack and the second gear.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention, through the setting of a fixing mechanism, causes the receiving plate to tilt synchronously when the goods are tilted, which in turn causes the receiving plate to drive the first gear to rotate. Under the meshing action of the first gear and the first rack, the first rack drives the inclined block to slide, which causes the starting frame to move away from the first rack along the inclined surface of the inclined block. In turn, the starting frame drives the slide groove to slide relative to the linkage rod. The two linkage rods drive the two clamping plates to move closer to each other along the slide groove, clamping and fixing the tilted goods stack from both sides, preventing the stacked goods stack from tilting further, thereby reducing the overall center of gravity shift tendency of the guide vehicle, and thus reducing the possibility of the guide vehicle overturning when turning.

[0013] 2. This invention utilizes a support plate to tilt heavy objects for assisted unloading. The cargo box is opened manually or with the help of a lifting device, causing the door to drive the third rack and the first gear to mesh. Under the meshing action of the third rack and the first gear, the first gear drives the support plate to tilt towards the side of the door, allowing the goods on the support plate to slide out of the cargo box along the tilted support plate, thus achieving the effect of assisted unloading and avoiding the time-consuming and laborious unloading caused by excessive weight of the goods.

[0014] 3. The present invention, through the setting of a balancing mechanism, causes the receiving plate to drive the first gear to rotate. Under the meshing action of the first gear and the first rack, the first rack drives the second rack to move. Since the second rack is distributed at both ends of the first rack, when the first rack moves, only the second rack near the tilting direction meshes with the second gear near the tilting side. Thus, under the meshing action of the second rack and the second gear, the second gear drives the deflection frame to rotate towards the tilting side of the goods. The deflection frame drives the mounting frame to rotate synchronously. The universal wheels support the ground, increasing the stability of the vehicle chassis and thus preventing the guide vehicle from overturning due to the tilting of the stacked goods.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0018] See Figures 1 to 10As shown, an automated guided vehicle (AGV) capable of stabilizing loads includes a vehicle body 1. A cargo box 11 is mounted on the top outer wall of the vehicle body 1. A receiving plate 2 is rotatably inserted into the inner wall of the cargo box 11 via a rotating shaft. A transmission chamber 111 is located inside the cargo box 11. A first gear 21 is mounted on the rotating shaft of the receiving plate 2 and rotatably inserted into the transmission chamber 111. A door 12 is slidably inserted into one side outer wall of the cargo box 11. A third rack 121, which meshes with the first gear 21, is fixed on the outer wall of the door 12. A fixing mechanism is provided inside the cargo box 11. A balancing mechanism is provided on the vehicle body 1. When the door 12 is moved upward to open the cargo box 11, the receiving plate 2 causes the cargo to tilt and unload towards the door 12. At the same time, the fixing mechanism is triggered by the meshing action of the first gear 21 and the first rack 3. The clamping plate 4 inside the cargo box 11 pushes the cargo towards the door 12. A second spring 52 is provided between the outer wall of the starting frame 5 and the inner wall of the cargo box 11.

[0019] It should be noted that in the initial state, the door 12 closes the cargo box 11, and the door 12 drives the third rack 121 to move to the bottom of the transmission chamber 111. The third rack 121 is located below the first gear 21. At this time, the rotation of the first gear 21 will not drive the third rack 121 to rotate.

[0020] When transporting goods, the goods are stacked on the receiving plate 2 inside the cargo box 11. When unloading the goods, the box door 12 is opened manually or with the help of a lifting device. This causes the box door 12 to drive the third rack 121 to mesh with the first gear 21. Under the meshing action of the third rack 121 and the first gear 21, the first gear 21 drives the receiving plate 2 to tilt towards the side where the box door 12 is located. This allows the goods on the receiving plate 2 to slide out of the cargo box 11 along the tilted receiving plate 2, achieving the effect of assisted unloading. This avoids the situation where unloading is time-consuming and laborious due to excessive weight of the goods. Compared with the existing technology that only has the function of transportation, this device can achieve the effect of assisted unloading by tilting heavy objects, which greatly improves work efficiency.

[0021] The fixing mechanism includes a first rack 3 slidably inserted into the bottom of the transmission chamber 111, which meshes with the first gear 21. A pair of symmetrically distributed inclined blocks 31 are welded to the outer wall of the first rack 3. A starting frame 5 that abuts against the inclined blocks 31 is slidably inserted into the bottom inner wall of the cargo box 11. A V-shaped groove 51 is provided on the outer wall of the starting frame 5. Clamping plates 4 are slidably inserted into the box door 12 and the inner wall of the cargo box 11 opposite the box door 12. A linkage rod 41 that is slidably inserted into the groove 51 is welded to the outer wall of each clamping plate 4. When the stacked goods tilt due to the shift of the center of gravity, the fixing mechanism drives the clamping plates 4 on both sides to fix the goods. A pair of first springs 22 symmetrically distributed on both sides of the first gear 21 are provided between the bottom outer wall of the receiving plate 2 and the inner wall of the cargo box 11.

[0022] It should be noted that in the initial state, under the action of the first spring 22 on both sides, the receiving plate 2 is in a horizontal state, and under the action of the second spring 52, the starting frame 5 and the inclined block 31 are kept in contact, and the two linkage rods 41 are located in the opening end of the V-shaped slide groove 51.

[0023] When loading goods, the goods are stacked on the receiving plate 2 inside the cargo box 11. Due to the different weights of each item or ground bumps, the stacked goods may tilt to one side inside the cargo box 11. The goods cause the receiving plate 2 to tilt synchronously, which in turn causes the receiving plate 2 to rotate the first gear 21. Under the meshing action of the first gear 21 and the first rack 3, the first rack 3 causes the inclined block 31 to slide. This causes the starting frame 5 to move away from the first rack 3 along the inclined surface of the inclined block 31. In turn, the starting frame 5 causes the sliding groove 51 to slide relative to the linkage rod 41. The two linkage rods 41 move along the sliding groove 51 to bring the two clamping plates 4 closer to each other, clamping and fixing the tilted goods stack from both sides to prevent the stacked goods stack from tilting further. This reduces the tendency of the overall center of gravity of the guided vehicle to shift, thereby reducing the risk of the guided vehicle overturning when turning.

[0024] In addition, when unloading goods, the cargo box 11 is opened by moving the upper door 12. At this time, the clamping plate 4 on the door 12 will move upward synchronously with the door 12, thereby avoiding the goods inside the cargo box 11. At the same time, the third rack 121 drives the first gear 21 to rotate, causing the first gear 21 to drive the first rack 3 to slide, thereby triggering the fixing mechanism to repeat the above process, causing the clamping plate 4 on the inner wall of the cargo box 11 to slide towards the side where the door 12 is located, thereby pushing the goods towards the side of the door 12, further improving the unloading effect.

[0025] The balancing mechanism includes a pair of second racks 32 mounted on the outer walls of both ends of the first rack 3. A pair of deflector frames 6 symmetrically distributed on both sides of the support plate 2 are rotatably inserted into the top outer wall of the vehicle body 1 via a pivot. A pair of protrusions 13 symmetrically distributed on both sides of the vehicle body 1 are provided on the outer wall of the end of the vehicle body 1 closest to the deflector frames 6. A second gear 61 meshing with the second racks 32 is mounted on the pivot of each deflector frame 6. A slide rod 71 is slidably inserted into the inner side of each deflector frame 6. A mounting bracket 7 is welded to the outer wall of the end of each slide rod 71 furthest from the vehicle body 1. A clearance groove 33 is provided on the outer wall of the first rack 3. The outer wall of each slide rod 71 is... Each mounting frame 7 is welded with a trigger rod 711 that slides into the clearance groove 33. A third spring 72 is provided between the outer wall of each mounting frame 7 and the outer wall of the deflection frame 6. A caster wheel 73 is rotatably connected to the outer wall of each mounting frame 7. A protective plate 74 is installed on the outer wall of each mounting frame 7. The impact is buffered by the set balancing mechanism. At the same time, the fixing mechanism is triggered by the trigger rod 711 to clamp and fix the goods during the impact. When the stacked goods are tilted due to the shift of the center of gravity, the balancing mechanism drives the deflection frame 6 to rotate the mounting frame 7 toward the tilted side of the receiving plate 2 under the meshing action of the second rack 32 and the second gear 61.

[0026] It should be noted that in the initial state, the two deflection frames 6 are in a parallel distribution, and the third spring 72 is in a naturally extended state.

[0027] Due to differences in the weight of each item or uneven ground, when the stacked goods in the cargo box 11 tilt to one side, the goods cause the receiving plate 2 to tilt synchronously, causing the receiving plate 2 to drive the first gear 21 to rotate. As a result, under the meshing action of the first gear 21 and the first rack 3, the first rack 3 drives the second rack 32 to move. Since the second rack 32 is distributed at both ends of the first rack 3, when the first rack 3 moves, only the second rack 32 on the side closer to the tilt direction meshes with the second gear 61 on the side closer to the tilt. As a result, under the meshing action of the second rack 32 and the second gear 61, the second gear 61 drives the deflection frame 6 to rotate towards the side of the tilted goods. The deflection frame 6 drives the mounting frame 7 to rotate synchronously. The universal wheels 73 support the ground, increasing the stability of the chassis of the vehicle body 1, thereby preventing the guide vehicle from overturning due to the tilting of the stacked goods.

[0028] Meanwhile, as the deflector 6 rotates, the mounting bracket 7 gradually extends along the protrusion 13 on the vehicle body 1, thereby increasing the degree of cargo tilt, increasing the tilt angle of the receiving plate 2, increasing the meshing stroke of the first gear 21 and the first rack 3, increasing the sliding stroke of the second rack 32, and increasing the meshing stroke of the second rack 32 and the second gear 61, thereby increasing the rotation angle of the deflector 6, increasing the extension length of the mounting bracket 7 along the protrusion 13, and thus increasing the stability of the vehicle body 1.

[0029] In addition, the third spring 72 and the protective plate 74 enable the balancing mechanism to buffer the impact on the front of the vehicle body 1, reducing the impact on the vehicle body 1. At the same time, when there is an impact, the mounting bracket 7 compresses the third spring 72, causing the slide rod 71 to drive the trigger rod 711 to slide in the avoidance groove 33. This causes the trigger rod 711 to push the starting bracket 5 away from the first rack 3, thereby triggering the fixing mechanism to drive the two clamping plates 4 to clamp and fix the cargo, preventing the cargo from hitting the inner wall of the cargo box 11 due to inertia during the impact, which would cause secondary damage.

[0030] Working principle: When transporting goods, the goods are stacked on the receiving plate 2 inside the cargo box 11. When the stacked goods tilt to one side due to the different weight of each item or ground bumps, etc. Under the action of the fixing mechanism, the cargo drives the receiving plate 2 to tilt synchronously, causing the receiving plate 2 to drive the first gear 21 to rotate. As a result, under the meshing action of the first gear 21 and the first rack 3, the first rack 3 drives the inclined block 31 to slide, causing the starting frame 5 to move away from the first rack 3 along the inclined surface of the inclined block 31. This causes the starting frame 5 to drive the slide groove 51 to slide relative to the linkage rod 41. The two linkage rods 41 drive the two clamping plates 4 to move closer to each other along the slide groove 51, clamping and fixing the tilted cargo stack from both sides, preventing the stacked cargo stack from tilting further, thereby reducing the overall center of gravity shift tendency of the guide vehicle, and thus reducing the chance of the guide vehicle overturning when turning. Under the action of the balancing mechanism, the receiving plate 2 drives the first gear 21 to rotate, so that under the meshing action of the first gear 21 and the first rack 3, the first rack 3 drives the second rack 32 to move. Since the second rack 32 is distributed at both ends of the first rack 3, when the first rack 3 moves, only the second rack 32 on the side closer to the tilt direction meshes with the second gear 61 on the side closer to the tilt direction. Thus, under the meshing action of the second rack 32 and the second gear 61, the second gear 61 drives the deflection frame 6 to rotate towards the side of the goods tilt. The deflection frame 6 drives the mounting frame 7 to rotate synchronously. The universal wheel 73 supports the ground, increasing the stability of the chassis of the vehicle body 1, thereby avoiding the situation where the guide vehicle will overturn due to the tilt of the stacked goods. When unloading goods, the cargo box 11 is opened manually or with the help of a lifting device by moving the door 12 upwards. This causes the door 12 to drive the third rack 121 to mesh with the first gear 21. Under the meshing action of the third rack 121 and the first gear 21, the first gear 21 drives the receiving plate 2 to tilt towards the side of the door 12. This allows the goods on the receiving plate 2 to slide out of the cargo box 11 along the tilted receiving plate 2, achieving the effect of assisted unloading. This avoids the time-consuming and laborious unloading caused by excessive weight of the goods. Compared with the existing technology that only has the function of transportation, this device can achieve the effect of assisted unloading by tilting heavy objects, which greatly improves the work efficiency. At the same time, through the fixed mechanism, the third rack 121 drives the first gear 21 to rotate, which in turn drives the first gear 21 to slide the first rack 3. This triggers the fixed mechanism to repeat the above process, causing the clamping plate 4 on the inner wall of the cargo box 11 to slide towards the side of the door 12. This further pushes the goods towards the door 12, improving the unloading effect.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
