An AI-powered obstacle avoidance and walking chassis

Abstract

This utility model relates to the field of chassis technology, specifically to an artificial intelligence automatic obstacle avoidance and walking chassis. It includes a chassis body with an annular slide rail. The annular slide rail has an upward-opening groove, and multiple baffles are slidably mounted in the groove. Limiting grooves are formed on the side walls of the groove. Limiting blocks are slidably mounted on the side of the baffles facing the limiting grooves. A pushing mechanism is connected to the limiting blocks. In its natural state, the limiting blocks extend into the limiting grooves under the action of the pushing mechanism. A locking mechanism is also included. The space formed by the multiple baffles, spaced apart and enclosed, is used for placing goods and protecting them from falling. The multiple baffles can slide along the annular slide rail, approaching and retracting towards each other. When this is done, the side of the space formed by the multiple baffles is open, facilitating the loading and unloading of goods. When it is necessary to lock the position of the baffles, simply pressing the locking mechanism will cause the limiting blocks to engage with the limiting grooves for locking, making the operation more convenient and faster.

Description

Technical Field

[0001] This utility model relates to the field of chassis technology, specifically to an artificial intelligence-based automatic obstacle avoidance and walking chassis. Background Technology

[0002] An AI-powered automatic obstacle avoidance chassis is an automated transport device that can move and carry goods in transportation or load-bearing environments. For example, the AI-powered chassis disclosed in patent documents with authorization announcement numbers CN115635834B and CN113500911B is a mobile platform that achieves autonomous obstacle avoidance through control system and sensor technology.

[0003] However, most existing AI-powered walking chassis do not have protective structures (such as the walking chassis disclosed above) during use. That is, they cannot effectively protect goods from impact or prevent goods placed on the chassis from moving and falling off. Goods are at risk of being damaged by collisions, and there is a high risk that goods will fall off the walking chassis if they are not placed stably or if there is external interference. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide an artificial intelligence automatic obstacle avoidance walking chassis, which can protect and limit the goods placed on the chassis, reduce the risk of goods being damaged by collision or falling off the chassis, so as to solve the technical problems described in the background art.

[0005] This utility model is achieved through the following technical solution:

[0006] An artificial intelligence-based automatic obstacle avoidance and walking chassis includes a chassis body, an annular slide rail arranged at the outer edge of the chassis body, the annular slide rail having an upward-opening groove, and a baffle slidably fitted in the groove;

[0007] A limiting groove is provided on the side wall of the slide. A limiting block is slidably assembled on the side of the baffle facing the limiting groove. A pushing mechanism is connected to the limiting block. In the natural state, the limiting block extends into the limiting groove under the action of the pushing mechanism.

[0008] It also includes a locking mechanism, which, under the intervention of external force, can push the limiting block to move and abut against the limiting groove, thereby locking the baffle.

[0009] Furthermore, the baffle has an installation groove on the side facing the limiting groove, and the limiting block is slidably assembled in the installation groove;

[0010] The pushing mechanism includes a slide rod fixedly connected in the mounting groove, and the center line of the slide rod is parallel to the movement trajectory of the limiting block;

[0011] The bottom of the limiting block is integrally formed with a slider, which is slidably connected to the slide rod. A spring is fitted on the slide rod. In its natural state, the limiting block extends out of the mounting groove under the outward force generated by the spring.

[0012] Furthermore, the baffle has a vertical hole inside, and the locking mechanism includes a vertical rod inserted vertically into the vertical hole. A ball is installed at the bottom of the vertical rod, and the limiting block has an inclined surface on the side facing the ball, with the inclined surface located directly below the ball.

[0013] A pushing component is connected to the vertical rod. When the vertical rod moves downward under the action of the pushing component, the ball presses against the inclined surface, thereby pushing the limiting block to move outward and abut against the limiting groove to lock the baffle.

[0014] The baffle is provided with a limit component to limit the travel of the vertical rod and continuously lock the baffle.

[0015] Furthermore, the baffle has a storage groove communicating with the vertical hole on its outward side. The pushing component includes a handle hinged in the storage groove. A push rod is hinged between the handle and the vertical rod. When the handle is pressed, the vertical rod is pushed downward by the push rod.

[0016] Furthermore, a second spring is also fitted outside the slider, and the second spring and the first spring are respectively placed on both sides of the slider.

[0017] Furthermore, a limiting hole is provided on the vertical rod, a side hole is provided on the side of the baffle, and the limiting component includes a limiting rod that is movably inserted into the side hole, and a spring is fitted around the limiting rod.

[0018] When the vertical rod moves and the limiting hole aligns with the side hole, the limiting rod is inserted into the limiting hole under the action of the spring three to restrict the vertical movement of the vertical rod.

[0019] Furthermore, the limiting assembly also includes a limiting ring fixedly connected to the outward opening of the side hole, and the two ends of the spring three abut against the limiting rod and the limiting ring respectively.

[0020] Furthermore, the limiting groove protrudes outward from the groove wall of the limiting block to form a protrusion, and the limiting block has a groove on the side facing the protrusion that matches the shape of the protrusion.

[0021] The beneficial effects of this utility model are as follows:

[0022] 1. An annular slide rail is arranged on the outer edge of the chassis body. Multiple baffles are slidably mounted on the annular slide rail at intervals. The space formed by the multiple baffles unfolding and closing at intervals is used for placing goods and for impact protection and preventing the goods from falling. The multiple baffles can slide along the annular slide rail and move closer to each other and close together. At this time, the side of the space formed by the multiple baffles is open, which is conducive to the loading and unloading of goods.

[0023] 2. When the baffle is inserted downward into the slide groove, the groove wall of the slide groove presses the limiting block into the mounting groove through the inclined surface. After the baffle is inserted vertically into the slide groove, the pushing mechanism pushes the limiting block out of the mounting groove and into the limiting groove, quickly completing the installation of the baffle. At this time, the limiting block can vertically limit the baffle, so that the baffle can only slide along the slide groove, preventing the baffle from disengaging from the annular slide rail.

[0024] 3. When it is necessary to lock the position of the baffle, simply press the locking mechanism to drive the limiting block to abut against the limiting groove for locking, making the operation more convenient and faster. Attached Figure Description

[0032] Typical embodiments embodying the features and advantages of this utility model will be specifically described in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0033] In the description of this application, the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the structure referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0034] Please see Figure 1 and Figure 2 This utility model provides a technical solution: an artificial intelligence automatic obstacle avoidance walking chassis, including a chassis body 1. The chassis body 1 adopts the intelligent walking chassis disclosed in the prior art with publication numbers CN113500911 B or CN115635834B. Through the combined use of various sensors, it can effectively sense and avoid obstacles. Its specific structure and working principle will not be described in detail here.

[0035] An annular slide rail 2 is arranged on the outer edge of the chassis body 1. A rubber layer can be provided on the outside of the annular slide rail 2 to reduce the impact force generated during collision. The annular slide rail 2 has an upward-opening groove 21. Multiple baffles 3 are slidably assembled in the groove 21 at intervals. The space formed by the multiple baffles 3 at intervals is used for placing goods and to protect the goods from impact and prevent them from falling.

[0036] Multiple baffles 3 can slide along the annular slide rail 2 and move closer to each other, at which time the space formed by the multiple baffles 3 is open on the side, which is conducive to the loading and unloading of goods.

[0037] Please see Figures 1 to 3 The slide 21 has an annular limiting groove 22 on its side wall, and the baffle 3 has an installation groove 31 on the side facing the limiting groove 22. A limiting block 4 is slidably assembled in the installation groove 31. A pushing mechanism 5 is connected to the limiting block 4. The pushing mechanism 5 includes a slide rod 51 fixedly connected in the installation groove 31. The center line of the slide rod 51 is parallel to the movement trajectory of the limiting block 4.

[0038] The bottom of the limiting block 4 is integrally formed with a slider 52, which is slidably connected to the slide rod 51. A spring 53 is fitted on the slide rod 51. In its natural state, the limiting block 4 extends out of the mounting groove 31 under the outward force generated by the spring 53.

[0039] The limiting block 4 has inclined surfaces at its outward end. When the baffle 3 is inserted downward into the slide groove 21, the groove wall of the slide groove 21 presses the limiting block 4 into the mounting groove 31 through the inclined surfaces. When the baffle 3 is inserted vertically into the slide groove 21, the spring 53 deforms back to its original state and pushes the slider 52 outward, thereby pushing the outward end of the limiting block 4 out of the mounting groove 31 and into the limiting groove 22. At this time, the limiting block 4 can vertically limit the baffle 3, so that the baffle 3 can only slide along the slide groove 21, preventing the baffle 3 from detaching from the annular slide rail 2.

[0040] Please see Figure 2 and Figure 3 The baffle 3 is equipped with a locking mechanism 6 for pushing the limiting block 4 to move and abut against the limiting groove 22, thereby locking the baffle 3. The baffle 3 has a vertical hole 32 inside. The locking mechanism 6 includes a vertical rod 61 inserted vertically into the vertical hole 32. In order to reduce the weight of the chassis, the vertical rod 61 can be a hollow rod structure. A ball bearing 62 is installed at the bottom of the vertical rod 61. The limiting block 4 has an inclined surface 41 on the side facing the ball bearing 62. The inclined surface 41 is located directly below the ball bearing 62.

[0041] The baffle 3 has a storage groove 33 communicating with the vertical hole 32 on its outward side. A pushing component 63 is connected to the vertical rod 61. The pushing component 63 includes a handle 631 hinged in the storage groove 33. A push rod 632 is hinged between the handle 631 and the vertical rod 61. When the handle 631 is pressed, the vertical rod 61 is pushed downward by the push rod 632. At this time, the ball bearing 62 squeezes the inclined surface 41, thereby pushing the limiting block 4 to move outward and abut against the limiting groove 22 to lock the baffle 3. After the baffle 3 is locked, the sliding of the baffle 3 is restricted, thereby ensuring the stability of the goods placement.

[0042] Secondly, by rolling and pushing the limiting block 4 with the ball 62, the friction generated during the movement of the limiting block 4 can be reduced, making the operation smoother.

[0043] Please see Figure 3 The limiting groove 22 protrudes outward from the groove wall of the limiting block 4 to form a protrusion 23. The limiting block 4 has a groove 42 that matches the shape of the protrusion 23 on the side facing the protrusion 23. When the limiting block 4 abuts against the limiting groove 22 under the action of the pushing component 63, the contact area between the limiting block 4 and the limiting groove 22 can be increased by the cooperation of the protrusion 23 and the groove 42, thereby increasing the friction and further improving the locking effect.

[0044] Please see Figure 3 A second spring 633 is also fitted outside the slide rod 51. The second spring 633 and the first spring 53 are respectively placed on both sides of the slider 52. When the force on the limiting block 4 is released, the second spring 633 deforms back to its original state, thereby pushing the limiting block 4 partially back into the mounting groove 31, thereby releasing the abutment state between the limiting block 4 and the limiting groove 22. In this state, the baffle 3 can slide freely along the slide groove 21.

[0045] Please see Figure 2 and Figure 4 The vertical rod 61 has a limiting hole 611, the side of the baffle 3 has a side hole 34, the baffle 3 is provided with a limiting component 64, the limiting component 64 includes a limiting rod 641 movably inserted into the side hole 34, a limiting ring 643 is fixedly connected in the outward opening of the side hole 34, and a spring 642 is fitted on the limiting rod 641. The two ends of the spring 642 abut against the limiting rod 641 and the limiting ring 643 respectively.

[0046] When the vertical rod 61 moves downward under the action of the pushing component 63 and pushes the limiting block 4 to abut and lock against the limiting groove 22, the limiting hole 611 aligns with the side hole 34 during the movement of the vertical rod 61, and the limiting rod 641 is inserted into the limiting hole 611 under the action of the spring 642 to restrict the vertical movement and reset of the vertical rod 61, thereby continuously locking the baffle 3;

[0047] When it is necessary to disengage from the locked state, simply pull the limiting rod 641 outward to disengage it from the limiting hole 611. At this time, the spring 633 deforms and pushes the limiting block 4 to reset. During the reset process, the limiting block 4 pushes the vertical rod 61 upward. When the vertical rod 61 moves upward, it pushes the handle 631 to open through the push rod 632, facilitating the next locking operation.

[0048] When the limiting rod 641 is released, the limiting rod 641 abuts against the outer surface of the vertical rod 61 under the action of the deformation of the spring 642, so that it can automatically extend into the limiting hole 611 to restrict the movement of the vertical rod 61 during the next locking operation, thus ensuring the stability of the locking state.

[0049] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
