[0060] like Figures 1 to 21 As shown together, this embodiment also discloses a safety buffer device, including the profile frame mentioned above, and also including a buffer sponge layer 2, a safety touch edge strip 3 and a protective rubber layer 4. The bottom of the buffer sponge layer 2 is provided with a positioning groove 21 adapted to the positioning protrusion 15. The buffer sponge layer 2 is installed on the top surface of the profile frame through the positioning protrusion 15 and the positioning groove 21, and the buffer sponge layer 2 is fixedly connected to the profile frame. The top of the buffer sponge layer 2 is provided with a mounting groove 22, and the safety touch edge strip 3 is arranged in the mounting groove 22. The protective rubber layer 4 covers the safety touch edge strip 3, the buffer sponge layer 2 and the profile frame.

[0061] The safety buffer device is installed on the moving part through a profile frame, and the protective rubber layer 4 realizes safety protection of the internal structure. When subjected to external pressure or impact, the buffer sponge layer 2 realizes force buffering and plays a role in impact protection. At the same time, the safety touch edge strip 3 located in the mounting groove 22 at the top of the buffer sponge layer 2 is subjected to extrusion force or shear force, so that the external pressure or impact signal can be detected, and the detection signal is fed back to the control system, and the control system controls the moving part to stop working; because the safety touch edge strip 3 is located in the mounting groove 22 at the top of the buffer sponge layer 2, and the protective rubber layer 4 covers the safety touch edge strip 3, the safety touch edge strip 3 has a high detection sensitivity to external pressure or impact, and when subjected to external pressure or impact, it can ensure that the moving part stops working in time to avoid accidents, and the use is safe and reliable.

[0062] In one embodiment, if Figures 1 to 5 , Figure 6 , Figure 8 and Fig. 9 As shown in the figure, the inner side of the bottom of the protective rubber layer 4 has an integrally formed clip 41, which is an umbrella-shaped structure. The clip 41 is clipped into the clip slot 14, and the protective rubber layer 4 is connected to the profile frame through the clip 41 and the clip slot 14.

[0063] In one embodiment, if Figure 5 , Figure 6 , Figure 8 and Fig. 9 As shown in the figure, the inner side of the top of the protective rubber layer 4 has an integrally formed bead 42, and the bead 42 corresponds to the side of the safety touch edge strip 3. The bead 42 can apply pressure to the side position of the safety touch edge strip 3 through the bead 42 when subjected to lateral pressure or impact, making the detection of lateral pressure or impact more sensitive.

[0064] In one embodiment, as Figure 5 , Figure 6 , Figures 10 to 14 As shown together, the safety touch edge strip 3 includes an elastic rubber tube 31, and the elastic rubber tube 31 includes an integrally formed bottom portion and an arched portion. The bottom portion is used to adhere to the bottom surface of the mounting groove 22, and the arched portion is close to the protective rubber layer 4. The arched portion is deformed after being subjected to external pressure or impact, and is easy to reset after the external pressure or impact is removed. A first conductive rubber strip 32 is provided on the inner side of the bottom portion, and a second conductive rubber strip 33 corresponding to the first conductive rubber strip 32 is provided on the inner side of the arched portion. A deformation cavity 34 is formed between the first conductive rubber strip 32, the second conductive rubber strip 33 and the elastic rubber tube 31, and at least one conductive wire 35 is provided in the first conductive rubber strip 32 and the second conductive rubber strip 33 along their length directions.

[0065] When subjected to external pressure or impact, the elastic rubber tube 31 is deformed so that the second conductive rubber strip 33 contacts the first conductive rubber strip 32, thereby realizing the detection of external pressure or impact signals. The detection sensitivity is high, and it can meet the use requirements of external pressure or impact detection in all directions. The detection range is wide, and it can be reset in time after being subjected to external pressure or impact.

[0066] In one embodiment, if Fig.11 , Fig.13 and Fig.14 As shown together, the first conductive rubber strip 32 has a contact protrusion 321 on the side facing the second conductive rubber strip 33, and the contact protrusion 321 is arranged along the length direction of the first conductive rubber strip 32. The side of the second conductive rubber strip 33 facing the first conductive rubber strip 32 is a planar structure. Therefore, when subjected to external pressure or impact, it is easier to achieve contact between the second conductive rubber strip 33 and the first conductive rubber strip 32, and the detection sensitivity is high.

There is a gap between the two third conductive rubber strips 36, and a deformation cavity 34 is formed between the third conductive rubber strip 36 and the elastic rubber tube 31.

[0068] When subjected to external pressure or impact, the elastic rubber tube 31 will be deformed, so that the two third conductive rubber strips 36 are in contact with each other, thereby realizing the detection of external pressure or impact signals. The elastic rubber tube 31 is a flat structure, and the two third conductive rubber strips 36 are respectively located at the top and bottom of the inner side of the elliptical tube hole of the elastic rubber tube 31, which makes it easier to realize the contact and conduction of the two third conductive rubber strips 36, and the detection sensitivity is high. In addition, the safety edge touch anti-collision strip has a simple structure, low manufacturing cost, and is easy and convenient to install and use.

[0069] In another embodiment, if Figures 16 to 20 As shown in the figure, the elastic rubber tube 31 has a strip-shaped protrusion 311 on one side close to the protective rubber layer 4, and the strip-shaped protrusion 311 is an integrally formed structure of the elastic rubber tube 31. The strip-shaped protrusion 311 increases the structural strength of the elastic rubber tube 31, and when it is subjected to slight external pressure or impact, the external pressure or impact force will act on the strip-shaped protrusion 311, making the two third conductive rubber strips 36 easier to contact, further improving the detection sensitivity of the safety touch edge strip 3.

[0070] In another embodiment, if Figures 18 to 20 As shown together, the opposite side of the third conductive rubber strip 36 is an arc-shaped structure, and the middle distance between the cross-sections of the two third conductive rubber strips 36 is smaller than the edge distance; when subjected to external pressure or impact, the two third conductive rubber strips 36 are easier to contact, and the detection sensitivity is higher. When subjected to external pressure or impact, the elastic rubber tube 31 is deformed, so that the two third conductive rubber strips 36 are in contact. At this time, the two third conductive rubber strips 36 at the position subjected to external pressure or impact separate the deformation cavity 34 into two independent parts.

[0071] In one embodiment, if Fig.12 , Fig.15 , Fig.17 and Fig.21As shown together, a tube end plug-in 37 is provided at the end of the elastic rubber tube 31, and the tube end plug-in 37 includes an integrally formed insertion portion 371 and a wire dividing portion 372, the insertion portion 371 is adapted to the deformation cavity 34 and inserted into the deformation cavity 34, the wire dividing portion 372 is located outside the elastic rubber tube 31, and wire avoiding grooves 3721 corresponding to the conductive wire 35 are respectively opened on both sides of the wire dividing portion 372, the conductive wire 35 respectively extends into the wire avoiding grooves 3721 and is connected with a conductive wire 38, and a waterproof plug 39 is provided between the conductive wire 38 and the elastic rubber tube 31, the waterproof plug 39 wraps the wire dividing portion 372 and the connection terminals of the conductive wire 35 and the conductive wire 38, and the waterproof plug 39 is integrally injection molded with the conductive wire 38 and the elastic rubber tube 31. The provided tube end plug 37 is convenient for separating the two conductive wires 35. When in use, the tube end plug 37 is installed on the end of the elastic rubber tube 31, and then the conductive wire 35 and the wire 38 are connected. Thereafter, the connected components are placed in the injection molding equipment, and the waterproof plug 39 is obtained by the injection molding process. Since the waterproof plug 39 wraps the wiring ends of the conductive wire 35 and the wire 38, a good sealing of the wiring ends is achieved, and the waterproof plug 39 is integrally formed with the wire 38 and the elastic rubber tube 31, it has better waterproof performance, achieves a complete waterproof seal, and greatly extends the service life of the safety touch edge strip 3.

[0072] In one embodiment, the conductive wire 35 includes bulletproof wire, copper foil wire and silver foil wire. The copper foil wire and silver foil wire are wound on the bulletproof wire, which greatly improves the conductive performance of the conductive wire 35 and has good toughness and yield resistance, thereby greatly improving the detection sensitivity and service life of the safety touch edge strip 3.

[0073] It can be understood that the structure of the safety edge strip 3 includes but is not limited to the above two structures, and other safety edge strip 3 structures with pressure detection function can also be installed and used.

[0074] It can be understood that the safety buffer device can be installed on moving parts such as machine tool workbenches and electric doors that are subject to the risk of extrusion and shearing. It can also be installed and used in industrial production, automated warehouses, logistics systems, amusement facilities and other fields. For example, it can be installed on a rail-mounted AGV cart for use. It is not only simple and convenient to install and operate, but also can provide good safety protection.
