Abstract
Description
Technical Field
[0001] This utility model relates to the field of safety protection equipment, and in particular to a safety edge anti-collision strip that can be installed at corners. Background Technology
[0002] A safety edge, also known as a safety contact edge, is a strip-shaped pressure-sensitive switch. Safety edges and safety buffers are flexible, bendable strips that can be fixed to the edges of moving parts where there is a risk of crushing or shearing, such as machine tool tables and electric doors.
[0003] Currently, during the use of equipment such as scissor lifts, AGVs (Automated Guided Vehicles), lifting platforms, stages, and movable doors, the moving parts are highly susceptible to colliding with personnel, posing a risk of injury. To avoid such injuries, existing technologies typically determine the obstacle status by detecting motor current parameters or by installing anti-pinch strips to more directly sense obstacles and reduce harm. However, existing anti-pinch strips have significant drawbacks: while the conductive parts of the anti-pinch section deform under impact and pressure, the anti-pinch section itself is not easily deformed due to internal support or straight edges; at bends in the equipment, two anti-pinch strips need to be bonded together, but the bonded area is also difficult to deform, easily creating blind spots and posing safety hazards.
[0004] In addition, Chinese patent CN218616962U discloses a safety anti-collision connector for AGV vehicles. Although it achieves corner installation by designing the inner angle of the bent aluminum rail to be a right angle, it can only guarantee protection in the horizontal direction. There are still blind spots in the vertical direction, and it cannot completely avoid the risk of collision at corners. Utility Model Content
[0005] To address the aforementioned technical problems, this utility model provides a safety edge anti-collision strip that can be installed at corners.
[0006] The technical solution includes an integrally formed right-angled aluminum profile and a rubber skeleton that is detachably connected to the aluminum profile, wherein a number of conductive rubber strips are inserted into the rubber skeleton.
[0007] A set of insertion slots is provided on each of the two outer sides of the aluminum profile, and the rubber skeleton is connected to the aluminum profile through the insertion slots;
[0008] The rubber skeleton includes an integrally formed mounting part and an arched part. The horizontal projection of the mounting part is L-shaped, and a set of mounting guide rails are respectively provided on the two inner sides. The mounting guide rails are engaged with the insertion slot.
[0009] The outer surface of the arched part is arc-shaped, and several receiving holes are opened on the arched part. Each receiving hole is equipped with a conductive rubber strip, which can deform and trigger an electrical signal when it is subjected to collision and compression.
[0010] Preferably, the conductive strip is in the shape of a hollow tube, with two opposing longitudinal conductive strips on its inner wall.
[0011] Preferably, the cross-section of the conductive adhesive strip is an oblong ring, a rectangular ring, or a circular ring.
[0012] Preferably, the conductive strip is a metal conductive wire, specifically a copper wire or an aluminum wire.
[0013] Preferably, the number of receiving holes is 3-6, and they are evenly distributed along the length of the rubber skeleton.

[0026] Example 1
[0027] See Figures 1 to 4 This utility model provides a corner-mountable safety edge anti-collision strip, including an integrally formed right-angle aluminum profile 1, which serves as the supporting frame for the entire anti-collision strip. It is manufactured using an integral molding process, and the corner angle is 90°, which can completely fit the right-angle corners of equipment such as scissor lift platforms and AGV unmanned vehicles; and a rubber frame 2 that is detachably connected to the aluminum profile 1, with several conductive rubber strips 8 inserted on the rubber frame 2.
[0028] A set of insertion slots 3 are provided on each of the two outer sides of the aluminum profile 1, and the rubber frame 2 is connected to the aluminum profile 1 through the insertion slots 3;
[0029] The rubber skeleton 2 includes an integrally formed mounting part 4 and an arched part 5. The horizontal projection of the mounting part 4 is L-shaped, and a set of mounting guide rails 6 are respectively provided on the two inner sides. The mounting guide rails 6 are engaged with the insertion groove 3.
[0030] During installation, align the mounting guide rail 6 with the insertion slot 3, press and slide to the limit position to complete the assembly. To disassemble, slide in the opposite direction to separate, achieving quick assembly and disassembly.
[0031] The outer surface of the arched part 5 is arc-shaped, and the radius of the arc can be designed according to the protection requirements. This structure can reduce the impact force during collision and reduce the injury to personnel or objects. Furthermore, the arched part 5 has several receiving holes 7, and each receiving hole 7 is equipped with a conductive rubber strip 8. The conductive rubber strip 8 can deform and trigger an electrical signal when subjected to collision and compression.
[0032] When the arched part 5 is subjected to collision and compression, it deforms and triggers an electrical signal; after the electrical signal is transmitted to the equipment control system, it can immediately control the equipment to stop running, thereby achieving safety protection.
[0033] The conductive strip 8 is in the shape of a hollow tube, with two opposing longitudinal conductive strips on its inner wall.
[0034] The cross-section of the conductive adhesive strip 8 is a waist-shaped ring, a rectangular ring, or a circular ring.
[0035] The conductive strip is a metallic conductive wire, specifically a copper or aluminum wire.
[0036] When the arched part 5 is subjected to collision and compression, the hollow conductive strip 8 deforms, the two longitudinal conductive strips come into contact and form a conductive circuit, triggering an electrical signal; after the electrical signal is transmitted to the equipment control system, it can immediately control the equipment to stop running, thereby achieving safety protection.
[0037] The number of receiving holes 7 is 3-6, and they are evenly distributed along the length of the rubber skeleton 2.
[0038] The aluminum profile 1 has several mounting holes. The aluminum profile 1 can be fixed to the corner of the equipment by screws passing through the mounting holes.
[0039] An adhesive layer is provided on both inner sides of the aluminum profile 1.
[0040] The aluminum profile 1 has an adhesive layer on both inner sides, and the surface of the adhesive layer is covered with release paper. After peeling off the release paper, it can be directly pasted onto the surface of the equipment. It can be used with the mounting holes to achieve double fixation and improve installation stability. The aluminum profile 1 has both mounting holes and adhesive layer, which can be adapted to the surface of equipment made of different materials such as sheet metal, plastic, and silicone, and the installation method is flexible.
[0041] When using this utility model, the aluminum profile 1 is fixed at the corresponding position of the vehicle corner, the mounting guide rail 6 on the inner side of the mounting part 4 of the rubber frame 2 is aligned with the insertion grooves 3 on the two outer sides of the aluminum profile 1, the rubber frame 2 is pressed and slid along the insertion grooves 3 to the limit position, and the rubber frame 2 and the aluminum profile 1 are fixed together. At this time, the arched part 5 of the rubber frame 2 faces outward and is in a state that can receive collisions.
[0042] When the vehicle is driving or turning, if the arched part 5 of the rubber frame 2 collides with an obstacle or person before the vehicle, the arched part 5 is squeezed, the conductive rubber strip 8 in the receiving hole 7 is deformed, and the two longitudinal conductive strips on its inner wall come into contact, triggering an electrical signal.
[0043] The electrical signal is transmitted to the vehicle's control system. Upon receiving the signal, the control system promptly stops the vehicle to prevent a collision and further damage, thereby protecting the vehicle and surrounding personnel.
[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
