[0002] Robots equipped with drive mechanisms and intelligent recognition mechanisms, such as LiDAR, can automatically walk and avoid obstacles, and can achieve a variety of functions depending on the application scenario.

[0003] The prior art (application number 202122569758.5, published on April 15, 2022) describes an intelligent robot for intelligent obstacle recognition, comprising a main body and a shock-absorbing component for protecting the main body. The shock-absorbing component includes a slot on the side wall of the main body, a groove inside the slot, a slider inside the groove, a first support rod on the upper surface of the slider, a cavity inside the first support rod, a limiting block inside the cavity, a second support rod on the outer surface of the limiting block, a first spring inside the cavity, and a baffle at one end of the second support rod. One end of the first spring is fixedly connected to the bottom of the cavity, and the other end of the first spring is fixedly connected to the limiting block. This invention solves the problem of insufficient protection in existing intelligent robots for intelligent obstacle recognition by setting up a main body, slot, groove, slider, first support rod, cavity, limiting block, second support rod, and baffle.

[0004] Currently, robots identify obstacles by directly relying on a set of recognition modules, which has a relatively limited recognition range. Furthermore, the robot's outer shell may not recognize obstacles when moving, which can easily cause collisions. Some robots with anti-collision protection functions also have an increased external space requirement. Utility Model Content

[0005] The purpose of this invention is to provide a robot that can quickly identify obstacles, in order to solve the problems mentioned in the background art, where current robots rely directly on a set of identification modules to identify obstacles, which has a limited identification range, and the robot's outer shell is prone to collisions when it does not identify obstacles during movement.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a robot capable of quickly identifying obstacles, comprising a robot body and a moving mechanism below it. The moving mechanism is located below the robot body and provides power to the robot body. An intelligent recognition module is installed above the robot body, and the intelligent recognition modules are distributed at equal angles around the center of the robot body to identify obstacles at different angles. A protective cover is nested on the outside of the robot body, and a through groove is opened inside the protective cover. The through groove is correspondingly set with the intelligent recognition module. After the protective cover rotates, it wipes and blocks the intelligent recognition module. A rotating mechanism is set in the middle of the protective cover to control the rotation of the protective cover, and an anti-collision mechanism is set on the outside of the protective cover.

[0007] To further optimize this technical solution, the rotating mechanism includes a drive shaft, which is mounted on top of the robot body. The drive shaft is connected to the protective cover to provide power to the protective cover, and the lower part of the drive shaft is connected to the motor output shaft to obtain rotational power.

[0008] To further optimize this technical solution, a docking mechanism is provided between the drive shaft and the protective cover, and the drive shaft and the protective cover are detachably connected through the docking mechanism.

[0009] To further optimize this technical solution, the docking mechanism includes a transmission block and a locking block. The transmission block is rectangular and fixed above the drive shaft. The center of the protective cover has a groove that is nested with the transmission block. The upper part of the transmission block is threaded with a locking block, which presses the protective cover against the outside of the transmission block.

[0010] To further optimize this technical solution, the anti-collision mechanism includes a protective plate and an automatic retraction mechanism. The protective plate is evenly distributed on the outer side of the protective cover, and the inner end of the protective plate is connected to the automatic retraction mechanism.

[0011] To further optimize this technical solution, a buffer plate is nested at the outer end of the protective plate, and a reset spring is fixed inside the buffer plate, with the reset spring and the protective plate being fixedly connected.

[0012] To further optimize this technical solution, the automatic retraction mechanism includes a mounting shaft, a torsion spring, a transmission gear, a movable rack, and a top block;

[0013] The mounting shaft is fixed to the inner end of the protective plate, and the protective plate and the protective cover are rotatably connected through the mounting shaft;

[0014] A torsion spring is positioned on the outside of the mounting shaft to provide rotational restoring force for the mounting shaft;

[0015] The transmission gear is fixedly connected to the end of the mounting shaft;

[0016] The movable rack is located on the outside of the transmission gear and forms a meshing connection with the transmission gear. The movable rack and the protective cover form an up-and-down sliding structure, and ball bearings are provided below the movable rack.

[0017] The top block is fixed to the surface of the robot body, and its top cross-section is an arc-shaped structure located below the movable rack. The upper surface of the top block is designed with an inclined structure.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] (1) By setting up multiple sets of intelligent recognition modules, obstacles in multiple directions can be recognized, thereby improving the obstacle recognition range. The protective cover on the outside of the intelligent recognition module can be rotated. After the equipment is stopped, the protective cover rotates to shield and protect the intelligent recognition module. At the same time, it can also clean the surface of the intelligent recognition module and maintain its good recognition effect.

[0020] (2) The protective cover can be removed from the outside of the robot body, which makes it convenient to clean and maintain the inside of the protective cover. The protective cover is installed in a ring on the outside of the robot body, and the outer side is equipped with a protective plate, which can provide anti-collision protection for the movement of the robot body.

[0021] (3) The protective plate can be rotated and stored on the surface of the protective cover, thereby reducing the space occupied when the device is stored, making it convenient to store and carry. The rotation of the protective plate and the rotation of the protective cover are linked together. After the protective cover protects the intelligent identification module, the protective plate can be automatically retracted. Attached Figure Description

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.

[0033] Please see Figures 1-9 Example 1: This utility model provides the following technical solution: A robot capable of quickly identifying obstacles, comprising a robot body 1 and a moving mechanism below it. The moving mechanism is located below the robot body 1 and provides power to the robot body 1. An intelligent recognition module 2 is installed on the top of the robot body 1, and the intelligent recognition modules 2 are distributed at equal angles with the center of the robot body 1 as the center, and identify obstacles at different angles. A protective cover 3 is nested on the outside of the robot body 1, and a through groove 4 is opened inside the protective cover 3. The through groove 4 is correspondingly set with the intelligent recognition module 2. After the protective cover 3 rotates, it wipes and blocks the intelligent recognition module 2. A rotating mechanism is set in the middle of the protective cover 3 to control the rotation of the protective cover 3, and an anti-collision mechanism is set on the outside of the protective cover 3.

[0034] The mobile mechanism can be set up in the form of tracks or rollers, and work with the intelligent recognition module 2 to detect and identify external obstacles. The intelligent recognition module 2 can be an existing mature recognition module such as radar or sensor. When the intelligent recognition module 2 is in use, the through slot 4 on the protective cover 3 corresponds to the intelligent recognition module 2, so that the intelligent recognition module 2 is exposed.

[0035] Example 2: Based on Example 1, a rotating mechanism is disclosed, including a drive shaft 5. The drive shaft 5 is installed above the robot body 1. The drive shaft 5 is connected to the protective cover 3 to provide power to the protective cover 3. The lower part of the drive shaft 5 is connected to the motor output shaft to obtain rotational power. A docking mechanism is provided between the drive shaft 5 and the protective cover 3. The drive shaft 5 and the protective cover 3 are detachably connected through the docking mechanism. The docking mechanism includes a transmission block 6 and a locking block 7. The transmission block 6 is rectangular and fixed above the drive shaft 5. The middle part of the protective cover 3 is provided with a groove that is nested with the transmission block 6. The upper part of the transmission block 6 is threadedly connected to the locking block 7, which presses the protective cover 3 against the outside of the transmission block 6.

[0036] The rotation of the drive shaft 5 can drive the protective cover 3 to rotate, switching the protection state of the protective cover 3 for the intelligent identification module 2. The protective cover 3 can also be disassembled. To disassemble the protective cover 3, first rotate the locking block 7 to release the connection between the locking block 7 and the transmission block 6. Then, the protective cover 3 can be moved upward and removed from the outside of the transmission block 6, thus disassembling the protective cover 3.

[0037] Example 3: Based on Example 1, an anti-collision mechanism is disclosed, comprising a protective plate 8 and an automatic retraction mechanism. The protective plates 8 are evenly distributed on the outer side of the protective cover 3, and the automatic retraction mechanism is connected to the inner end of the protective plate 8. A buffer plate 9 is nested at the outer end of the protective plate 8, and a return spring 10 is fixed inside the buffer plate 9. The return spring 10 and the protective plate 8 are fixedly connected. The automatic retraction mechanism includes a mounting shaft 11, a torsion spring 12, a transmission gear 13, a movable rack 14, and a top block 15. The mounting shaft 11 is fixed to the inner end of the protective plate 8, and the protective plate 8 forms a connection between the mounting shaft 11 and the protective cover 3. A rotatable connection is provided, a torsion spring 12 is provided on the outside of the mounting shaft 11 to provide rotational reset force for the mounting shaft 11, a transmission gear 13 is fixedly connected to the end of the mounting shaft 11, a movable rack 14 is provided on the outside of the transmission gear 13 and forms a meshing connection with the transmission gear 13, and the movable rack 14 and the protective cover 3 form an up-and-down sliding structure, and a ball is provided below the movable rack 14, and a top block 15 is fixed to the surface of the robot body 1, and the top block 15 has a circular arc structure in its top view section and is located below the movable rack 14, and the upper surface of the top block 15 has an inclined structure design.

[0038] The protective plate 8 provides collision protection for the robot body 1. When the robot body 1 is no longer in use, the protective cover 3 can be rotated to shield the intelligent recognition module 2. When the protective cover 3 rotates, the movable rack 14 moves below the top block 15, relieving the upward pushing effect of the top block 15 on the movable rack 14. The torsion spring 12 drives the mounting shaft 11 to rotate, which in turn drives the protective plate 8 to rotate, storing the protective plate 8 on the surface of the protective cover 3, reducing the space occupied by the device and making it convenient for storage and carrying.
