On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0025] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0027] like Figure 1 to Figure 6As shown, in one embodiment of the utility model, a foldable obstacle ladder is involved, the foldable obstacle ladder is formed by a plurality of ladder elements 10 hinged to each other, the ladder elements 10 are arranged in an I-shaped shape, the ladder elements 10 include two side plates 1 and a crossbeam 2 erected between the two side plates 1, and the plurality of ladder elements 10 are hinged to each other through the side plates 1, so that two adjacent ladder elements 10 can be folded, and a structure for obstacle support is formed after folding. This embodiment is used for firefighting, security and other robots to cross obstacles, and is formed by a plurality of ladder elements 10 hinged to each other. When in use, two adjacent ladder elements 10 can be folded to form a support frame for the obstacle ladder, which plays a supporting role during the robot's driving process, so that the robot can cross obstacles. The problem that some existing robots have high steps and high difficulty in crossing is solved, and a foldable foldable obstacle ladder is adopted, which is easy to carry and can be used as a support for obstacles of any shape, and is highly practical.

[0028] The above embodiment can flexibly adapt to different obstacles. The ladder element 10 is set in an I-shaped shape, so that the entire foldable obstacle ladder can flexibly adapt to obstacles of different heights and shapes, which improves the scope of application and flexibility of obstacle crossing. Two adjacent ladder elements 10 are hinged to each other through the side panels 1, which can be folded and unfolded. When folded, a structure for obstacle crossing support is formed, which is convenient for the ladder to be stored and carried when not in use, saving space and improving portability. The design of the crossbeam 2 erected between the two side panels 1 and the side panels 1 being hinged to each other enables the foldable obstacle ladder to form a stable support structure after unfolding, which can withstand the pressure and weight during the obstacle crossing process and ensure safety in use. Due to the I-shaped setting and reasonable material selection, the foldable obstacle ladder can achieve a lightweight design while ensuring structural strength, which is easy to carry and operate. The foldable obstacle ladder can not only be used for obstacle crossing, but also can be used in various scenarios such as field and rescue, and has strong versatility and practicality.

[0029] Both ends of the side panels 1 are provided with hinge shafts 3, and the hinge shafts 3 are used to hinge the adjacent side panels 1. In this embodiment, the hinge shafts 3 are used for connection to ensure the hinge stability between the two adjacent side panels 1, which is convenient for the structure to be folded and unfolded for use.

[0030] The side panel 1 is provided with a hinge through-hole, and the hinge shaft 3 passes through the hinge through-hole on the side panel 1 and the hinge through-hole on the adjacent side panel 1 in sequence, so that the adjacent side panels 1 can move around the hinge shaft 3. In this embodiment, the hinge through-hole design facilitates the hinge shaft 3 to be retained inside after passing through, and the side panel 1 rotates along the hinge shaft 3 under the action of the hinge through-hole.

[0031] Both ends of the hinge shaft 3 are provided with a fixing head 31, and the fixing head 31 is used to fix and limit the two adjacent side panels 1. In this embodiment, the fixing head 31 is set to fix and limit the two ends. In actual use, one end can be a threaded head and the other end can be a nut. The specific hinge shaft 3 can also be set as a bolt, which saves costs. This design only needs to set the nut to be fixed to prevent it from falling off during use.

[0032] The inner side surface and the outer side surface between two adjacent side panels 1 are fitted together. In this embodiment, the fitting design of the inner side surface and the outer side surface facilitates assembly, the structure is stable and reliable, and folding and unfolding are more convenient.

[0033] The corners of the side panels 1 are provided with R-corners 11. In this embodiment, the R-corners 11 are provided to protect the structure, preventing the sharp corners from causing damage to the traveling robot, and also avoiding damage to the building that is crossing the obstacle.

[0034] The cross beam 2 is arranged at the center of the two side plates 1. In this embodiment, the cross beam 2 is arranged at the center to ensure the structural strength and stability, and also to limit the folding position of the ladder element 10.

[0035] The cross beam 2 is a right-angled structural member and is provided with a tip portion 21, which faces the width direction of the side plate 1. Specifically, a support portion 22 is provided at one end of the cross beam 2 away from the tip portion 21, and the support portion 22 extends outward from the tip portion 21. In this embodiment, by using a right-angled angle iron as a support, the structural strength is high, and the two sides are the tip portion 21 and the support portion 22, respectively, to ensure the structural support strength and durability.

[0036] The two ends of the cross beam 2 are fixedly connected to the side plate 1 by welding. In this embodiment, welding is adopted, which is suitable for mass production and has a stable and reliable structure. However, in actual use, it is not limited to connecting by screws, etc., as long as the structural support strength is ensured.

[0037] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
