[0004] Secondly, without the role of auxiliary mechanisms, the buffer mechanism may experience problems such as jamming and increased friction during use, and passive safety cannot be guaranteed when the buffer mechanism malfunctions.

[0005] Finally, without modular design and quick-installation structure, installing and replacing anti-collision devices requires more fixing structures and tools, making the operation complex and time-consuming, thus making the robot maintenance and upgrade process cumbersome and increasing downtime.

[0028] 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.

[0029] Example 1:

[0030] Please see Figures 1-5 A robot anti-collision structure includes a main body 1, a buffer mechanism, and a quick-installation mechanism. The buffer mechanism includes a connecting plate 2, a pressure plate 3, a connecting rod 4, a damper 5, and auxiliary components. The connecting plate 2 is fixedly installed on the main body 1 and detachably connected to the main body 1. The pressure plate 3 is rotatably connected to the connecting rod 4 and slidably connected to the connecting plate 2. One end of the connecting rod 4 is rotatably connected to the damper 5, and the damper 5 is fixedly installed in the connecting plate 2. The auxiliary components include a first buffer pad 6, a second buffer pad 7, and a roller 8. The first buffer pad 6 is fixedly installed on the pressure plate 3, the second buffer pad 7 is fixedly installed on the pressure plate 3, and the roller 8 is installed in the connecting plate 2 and rotatably connected to the connecting plate 2.

[0031] In this embodiment, the buffer mechanism includes a connecting plate 2, a pressure plate 3, a connecting rod 4, a damper 5, and auxiliary components. During use, when the main body 1's traveling wheels 14 operate, causing the main body 1 to collide with the wall, the pressure plate 3 is subjected to external pressure. The pressure plate 3 is forced to move closer to the connecting plate 2, while the first chuck 19 of the first connecting rod 17 on the pressure plate 3 slides in the first groove 21 of the connecting plate 2. The sliding of the pressure plate 3 causes a change in the position of the connecting rod 4, at which point the connecting rod 4 transmits force to the damper 5. The damper 5 is mounted on the mounting block 28, and the mounting block 28 is subjected to force by sliding in the connecting plate 2. At this time, the friction block 29 on the mounting block 28 slides in the third sliding groove 30 in the connecting plate 2 and begins to work on the damper 5. The heat generated by the friction block 29 sliding in the third sliding groove 30 is also circulated to the outside through the heat dissipation hole 23 on the connecting plate 2. After the damper 5 absorbs the force, the reaction of the damper 5 allows the mounting block 28 to reset and the connecting rod 4 to reset as well, so that the pressure plate 3 also returns to its original position.

[0032] In this embodiment, the auxiliary components include a first buffer pad 6, a second buffer pad 7, and a roller 8. In use, the first buffer pad 6 first contacts the wall surface. Due to its special material, it weakens the force and then transfers the force to the pressure plate 3. The pressure plate 3 then begins to contact the connecting plate 2. When the two are close, the second buffer pad 7 contacts the connecting plate 2 and relieves some of the force on the pressure plate 3. Then, the connecting rod 4 slides in the positioning groove 27 of the roller 8, thus completing the buffering of the main body 1 against the wall surface.

[0033] In this embodiment, the quick installation mechanism includes a connecting block 9, a spring 10, a contact plate 11, a fixing plate 12, and a fixing bolt 13. In use, the connecting plate 2 is first installed onto the main body 1, and then the connecting block 9 is installed onto the connecting plate 2. When the connecting block 9 is installed, the positioning hole 25 on the connecting block 9 is aligned with the positioning rod 24 on the connecting plate 2. Then the connecting block 9 begins to contact the connecting plate 2. At this time, the contact plate 11 contacts the connecting plate 2 and is compressed by the force. Meanwhile, the second chuck 20 on the second connecting rod 18 on the contact plate 11 slides in the second slide groove 22 of the connecting block 9. The fixing plate 12 installed on the connecting block 9 begins to enter the locking hole 16 on the upright plate 15 of the main body 1. At this time, the fixing bolt 13 is inserted into the connecting hole 26 and the fixing bolt 13 is tightened. The fixing bolt 13 engages with the connecting block 9 and the connecting plate 2 respectively, thereby fixing the connecting plate 2 onto the main body 1.

[0034] Example 2:

[0035] In summary, during use, the first step is to install the buffer device, such as the connecting plate 2. First, install the connecting plate 2 onto the main body 1, then install the connecting block 9 onto the connecting plate 2. During installation, the positioning hole 25 on the connecting block 9 should be aligned with the positioning rod 24 on the connecting plate 2. Then, the connecting block 9 begins to contact the connecting plate 2. At this time, the contact plate 11 contacts the connecting plate 2, and the force compresses the spring 10. Simultaneously, the second chuck 20 on the second connecting rod 18 on the contact plate 11 slides in the second groove 22 of the connecting block 9. The fixing plate 12 installed on the connecting block 9 begins to enter the locking hole 16 on the upright plate 15 of the main body 1. At this time, the fixing bolt 13 is inserted into the connecting hole 26, and the fixing bolt 13 is tightened. The fixing bolt 13 engages with the threads of the connecting block 9 and the connecting plate 2, thereby fixing the connecting plate 2 to the main body 1. Subsequently, when the main body 1 is running, there will be collisions. At this time, the pressure plate 3 will be subjected to external pressure. The pressure plate 3 is forced to move closer to the connecting plate 2, and the first chuck 19 of the first connecting rod 17 on the pressure plate 3 is in the connecting plate 2. The damper 5 slides in the first groove 21, and the sliding of the pressure plate 3 causes the position of the connecting rod 4 to change. At this time, the connecting rod 4 transmits the force to the mounting block 28 of the damper 5, and the mounting block 28 slides in the connecting plate 2 under the force. At the same time, the friction block 29 on the mounting block 28 slides in the third groove 30 in the connecting plate 2 and begins to work on the damper 5. The heat generated by the friction block 29 sliding in the third groove 30 is also circulated to the outside through the heat dissipation holes 23 on the connecting plate 2. After the damper 5 absorbs the force, the damper 5... The reaction causes the mounting block 28 to reset and the connecting rod 4 to reset as well, causing the pressure plate 3 to return to its original position. During the operation of the buffer mechanism, the first buffer pad 6 first contacts the wall. Due to its special material, it weakens the force and then transmits the force to the pressure plate 3. The pressure plate 3 then begins to contact the connecting plate 2. When the two are close, the second buffer pad 7 contacts the connecting plate 2 and relieves some of the force on the pressure plate 3. Then the connecting rod 4 slides in the positioning groove 27 of the roller 8, completing the buffering of the main body 1 against the wall.

[0036] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
