Technical Field

[0001] This utility model relates to the field of mobile vehicle technology, specifically to an anti-collision structure for an AI mobile vehicle. Background Technology

[0002] In the field of education, AI mobile vehicles are an important tool for students to learn about artificial intelligence, robotics, and programming. By developing and debugging these mobile vehicles, students can understand sensor principles, AI algorithm applications, and robot control technology, thus cultivating practical skills and innovative thinking.

[0003] In actual use, it was found that due to the blind spots of the sensors and the limitations of the sensor programming algorithm, students often failed to avoid obstacles in time during the movement of the mobile car, resulting in collisions and damage to the mobile car itself. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an anti-collision structure for an AI mobile car, which can buffer the collision and reduce the damage to the car body.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-collision structure for an AI mobile car, comprising a body, a protective cover on the outer periphery of the body, the body including a chassis and a top plate detachably connected to the chassis, a buffer unit connected to the chassis, the buffer unit including a rebounding buffer arm, one end of the buffer arm extending outward as a buffer end, the chassis and the top plate both having through connecting holes, the protective cover being fitted onto the outer periphery of the body through the connecting holes, and when a collision occurs, the protective cover moves towards the body to press against the buffer end, and the buffer arm provides cushioning.

[0006] The present invention is further configured such that: a sleeve rod is fixed on the chassis, a sleeve hole is provided on the buffer arm, the through hole of the buffer arm is sleeved on the outer periphery of the sleeve rod and can rotate around the sleeve rod, and a torsion spring is sleeved on the outer periphery of the sleeve rod, one end of the torsion spring is fixed to the buffer arm and the other end is fixed to the chassis.

[0007] The present invention is further configured such that: a threaded post is fixed on the chassis, and a limiting plate is detachably connected to the top of the threaded post; the limiting plate can contact the top of the buffer arm to limit the buffer arm in the vertical direction.

[0008] The present invention is further configured such that: a limit switch is installed on the limit plate, and the contact end of the limit switch extends along the extension direction of the buffer end.

[0009] The present invention is further configured such that: the inner side of the protective cover is provided with a connecting groove adapted to the outer periphery of the vehicle body, and the upper and lower sides of the connecting groove are respectively provided with through holes corresponding to the connecting holes, and a positioning bolt is installed in the connecting hole, the positioning bolt being used to limit the position of the protective cover.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] Because of the buffer unit, when the car collides, the protective cover is pressed towards the car body, pushing the buffer end to rotate the buffer arm and compress the torsion spring, thus achieving multi-stage buffering. Therefore, it effectively solves the technical problem of large damage to the car body when the car collides in the prior art. In addition, through the setting of limit switches, when the impact force is too large and the buffer arm deflects excessively, the limit switches can trigger a braking signal, and force the car to stop or change direction according to the corresponding control program, so as to further improve the safety of the car body protection.

[0017] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., 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 the invention and for simplifying the description, and do not indicate or imply that the device or element 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 the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] like Figures 1 to 4 As shown, this utility model discloses an anti-collision structure for an AI mobile car, including a body 1, with a protective cover 2 covering the outer periphery of the body 1. The body 1 includes a chassis 1-1 and a top plate 1-2 detachably connected to the chassis 1-1, i.e., the top plate 1-2 and the chassis 1-1 are detachably connected by bolts to facilitate disassembly and maintenance of internal components and overall assembly. The chassis 1-1 is connected to a buffer unit, which includes a spring-loaded buffer arm 31. The specific structure of the spring-loaded buffer arm 31 is as follows: a sleeve rod 32 is fixed on the chassis 1-1, and a sleeve hole is provided on the buffer arm 31. The through hole 21 of the buffer arm 31 is sleeved around the sleeve rod 32 and can rotate around the sleeve rod 32. A torsion spring 33 is fitted around the outer periphery of the sleeve rod 32. One end of the torsion spring 33 is fixed to the buffer arm 31, and the other end is fixed to the chassis 1-1, so that the buffer arm 31 can elastically unfold outward under normal conditions.

[0020] In addition, one end of the buffer arm 31 extends outward as a buffer end. When the protective cover 2 moves inward due to a collision, its inner wall presses against the buffer end, forcing the buffer arm 31 to rotate around the sleeve rod 32. The impact energy is absorbed by the deformation of the torsion spring 33. After the collision is resolved, the torsion spring 33 drives the buffer arm 31 to reset.

[0021] In this embodiment, the specific connection relationship between the protective cover 2 and the vehicle body 1 is as follows: multiple connecting holes 4 are evenly distributed along the circumference on both the chassis 1-1 and the top plate 1-2. The inner side of the protective cover 2 is provided with a connecting groove that matches the contour of the vehicle body 1. Through holes 21 are opened on the upper and lower sides of the connecting groove corresponding to the positions of the connecting holes 4. Positioning bolts are inserted into the through holes 21 and nuts are screwed in to fix it to the connecting holes 4, so that the protective cover 2 is limited to the outer periphery of the vehicle body 1. The specifications of the through holes 21 are larger than the specifications of the connecting holes 4. The buffer units are symmetrically arranged on the chassis 1-1. In this way, when the protective cover 2 is pressed in different directions, it can generate corresponding deflection and press the buffer end inward to fully adapt to different collision angles.

[0022] In this embodiment, a threaded post 5 is fixed on the chassis 1-1. A limiting plate 6 is detachably connected to the top of the threaded post 5. That is, by screwing a screw into or out of the threaded hole of the threaded post 5, the limiting plate 6 can be detachably connected. After installation, the limiting plate 6 can contact the top of the buffer arm 31, thus limiting the buffer arm 31 in the vertical direction and ensuring the stability of the connection of the buffer arm 31.

[0023] In this embodiment, a limit switch 7 is further installed on the limit plate 6. The contact end of the limit switch 7 extends along the extension direction of the buffer end. The signal end of the limit switch 7 can be electrically connected to the controller of the trolley. When the rotation angle of the buffer arm 31 exceeds the threshold, the contact end of the limit switch 7 is triggered by the downward pressure and sends a signal to the trolley controller. Through the corresponding program, operations such as stopping or reversing can be performed to further improve the safety of the vehicle body 1.

[0024] The specific implementation principle of this solution is as follows:

[0025] When the car collides, the protective cover 2 is pressed towards the car body 1, pushing the buffer end to rotate the buffer arm 31 and compress the torsion spring 33, thus achieving multi-stage buffering. If the impact force is too large and causes the buffer arm 31 to deflect excessively, the limit switch 7 triggers a braking signal, forcing the car to stop or change direction according to the corresponding control program. After the collision is resolved, the torsion spring 33 drives the buffer arm 31 to reset and pushes the protective cover 2 back to its original position. The protective cover 2 is preferably made of lightweight, high-strength composite material.

[0026] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
