Description

Technical Field

[0001] This utility model relates to the field of rescue equipment, specifically a followable rescue support device. Background Technology

[0002] In the field of wilderness rescue, timely and effective rescue operations are crucial for saving lives. However, traditional wilderness rescue currently faces many technical bottlenecks.

[0003] In complex terrain environments, the transportation of injured personnel usually relies on the cooperation of multiple people, which not only makes the rescue extremely inefficient, but also exposes rescuers to high risks brought about by complex terrain, such as landslides and falls, which seriously threatens the lives of rescuers.

[0004] Current self-propelled equipment mainly relies on conventional GPS positioning systems for positioning and movement. Although the current GPS positioning accuracy error can be controlled within 5-10 meters, this error may have unpredictable consequences during field rescues due to the difficulty in determining road conditions, leading to a decrease in rescue efficiency.

[0005] Furthermore, during wilderness rescue operations, medical equipment, transportation vehicles, and rescue tools are often separated, which means that the injured cannot receive necessary medical treatment in a timely manner while being transported to a safe area, greatly delaying the emergency response time and increasing the risk to the injured's lives. Utility Model Content

[0006] To address one of the shortcomings of existing technologies, this utility model provides a followable rescue carrying device to solve the problem of transferring the injured during existing field rescues.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a followable rescue carrying device, comprising:

[0008] The supporting mechanism can support the human body on its upper side;

[0009] A mobile mechanism is located below the support mechanism, with its upper part connected to the support mechanism and its lower part equipped with a track assembly.

[0010] Tracking agencies include:

[0011] The tag component can be carried by the human body;

[0012] The tracking component is electrically connected to the moving mechanism to form a control loop; the tracking component can control the moving mechanism to follow the movement of the tag component.

[0013] Preferably, the supporting mechanism includes:

[0014] The upper load-bearing section is a stretcher structure;

[0015] The lower support part is located below the upper support part, and a tool attachment structure is provided around the lower support part.

[0016] Preferably, the moving mechanism further includes:

[0017] The main power unit is connected to the lower bearing unit on its upper side; the track assembly is symmetrically arranged on two parallel horizontal sides of the main power unit; the tracking assembly is electrically connected to the main power unit to form a control loop.

[0018] Preferably, the moving mechanism further includes:

[0019] The obstacle avoidance assembly includes several obstacle avoidance sensors, which are disposed at both ends of the upper support portion along its length.

[0020] Preferably, the moving mechanism further includes:

[0021] The lighting assembly includes at least two lighting groups arranged around the periphery of the upper support portion.

[0022] Preferably, the tag assembly includes a wristband and a tag portion disposed on the wristband;

[0023] The tracking component includes a UWB positioning module.

[0024] Preferably, the tool includes:

[0025] The oxygen cylinder is attached to one side of the lower support.

[0026] Preferably, the tool further includes:

[0027] The shovel is attached to the side of the lower support unit away from the oxygen cylinder.

[0028] Preferably, the tool further includes:

[0029] The winch is located on the side of the lower support unit adjacent to the oxygen cylinder.

[0030] Preferably, it also includes:

[0031] A gas sensing component is disposed on the outside of the supporting structure. The gas sensing component can collect and report ambient gas.

[0032] Compared with existing technologies, this device offers the following advantages: It utilizes a control loop formed by a human-carryable tag and tracking component, enabling the device to automatically follow rescue personnel, thus solving the difficulties of transporting injured individuals collaboratively. In complex terrain environments, it not only effectively improves rescue efficiency but also reduces the risks faced by rescue personnel due to landslides, falls, and other high-risk situations, ensuring their safety.

[0033] Secondly, the tracking component using the UWB positioning module has higher positioning accuracy compared to traditional self-propelled devices that rely on GPS positioning. It can accurately follow the target and effectively avoid the problem of reduced rescue efficiency due to positioning errors.

[0034] Furthermore, the surrounding structure of the carrying mechanism can be used to integrate rescue tools and medical equipment such as oxygen cylinders, shovels, and winches, enabling the injured to receive necessary medical treatment and environmental remediation in a timely manner during transport to a safe area. This greatly shortens the emergency response time and reduces the risk to the injured's life. Attached Figure Description

Detailed Implementation

[0042] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0043] Please see Figures 1-5 This application provides the following technical solutions:

[0044] A followable rescue support device includes a support mechanism 1 and a moving mechanism 2. The support mechanism 1 supports the human body, and the moving mechanism 2 is located below the support mechanism 1. The moving mechanism 2 includes track components 21 and a power unit 22. The power unit 22 is connected to the support mechanism 1 on its upper side; a track component 21 is respectively installed on both horizontal sides of its lower part. The moving mechanism 2, together with the power unit 22 and the track components 21, forms an all-terrain mobile platform. Its specific internal structure can adopt existing technology, and its main purpose is to enable movement in the wild. For example, the power unit 22 can be an all-terrain adaptive chassis with six-wheel independent suspension and differential drive.

[0045] In addition, this solution also includes a tracking mechanism 3, which is used to enable the mobile mechanism 2 to follow the movement of the mobile mechanism 2. The mobile mechanism 3 includes a tag component 31 and a tracking component 32. The tag component 31 adopts a wristband structure, which includes a wristband and a tag portion set on the wristband. The wristband tag can be a ULM3-SH wristband tag. It uses an STM32L051K8U6 as the main control unit. The tracking component 32 and the main power unit 22 of the mobile mechanism 2 are electrically connected to form a control loop; the tracking component 32 can control the mobile mechanism 2 to follow the movement of the tag component 31. The tracking component 32 includes a UWB positioning module. With the help of the UWB positioning system, a PDOA phase difference direction finding algorithm is used, combined with TOF ranging to form a three-dimensional spatial coordinate solution. The UWB positioning module in this solution uses an operating frequency band of 3.5-6.5GHz. The PDOA base station in the UWB positioning module is installed on the outside of the main power unit 22, and works with the tag component 31 for positioning and tracking. The active unit within the main power unit 22 can adopt an STM32H743+FPGA dual-processor architecture, with an additional 48V20Ah lithium battery pack to ensure a range of more than 30km.

[0046] Based on the above implementation scheme, the supporting mechanism 1 includes an upper supporting part 11 and a lower supporting part 12. The upper supporting part 11 is a stretcher structure, but unlike conventional stretcher structures, it uses a rectangular frame as the outer support frame, with a flexible stretcher fabric inside the rectangular frame for internal support. This prevents the injured person from slipping off the upper supporting part 11. Several "n"-shaped binding frames are installed on the outer support frame of the upper supporting part 11, which, combined with straps, can secure the injured person. The lower supporting part 12 is located below the upper supporting part 11, and its periphery is equipped with a tool-attaching structure.

[0047] This device allows the injured person to be placed on the upper support unit 11, with one rescuer wearing a tag component 31 for walking guidance, and the moving mechanism 2 following along. Other rescuers can then monitor the injured person from the side of the device.

[0048] Based on the above implementation scheme, the tools for attaching the lower support section 12 can be selected according to the actual situation. This scheme provides several commonly used tool configurations, including an oxygen cylinder 4, a shovel 5, and a winch 6. The oxygen cylinder 4 is attached to one side of the lower support section 12. The shovel 5 is attached to the side of the lower support section 12 away from the oxygen cylinder 4. The winch 6 is located on the side of the lower support section 12 adjacent to the oxygen cylinder 4. In other words, the winch 6 is located on the front or rear side of the lower support section 12 in the direction of travel. The winch 6 is an electric winch with a rated load of up to 500 kg and a wire rope length of 50 m.

[0049] Oxygen cylinder 4 is used to provide oxygen to the injured, while shovel 5 and winch 6 are designed to be used during rescue operations due to the complexity of the wilderness rescue environment.

[0050] Based on the above implementation scheme, the moving mechanism 2 also includes an obstacle avoidance component 23, which includes a plurality of obstacle avoidance sensors, which are disposed at both ends of the upper bearing part 11 in the length direction.

[0051] The obstacle avoidance sensors include infrared TOF sensors, with four infrared TOF sensors arranged on the front and rear sides of the upper support 11 to construct a 120°×360° detection field. In addition, a millimeter-wave radar with an operating frequency of 24GHz is used to assist in terrain recognition.

[0052] Based on the above implementation scheme, the mobile mechanism 2 also includes a lighting assembly 24, which consists of two lighting groups. These two lighting groups are respectively located on the front and rear sides of the upper support portion 11, with each lighting group comprising two lights. By combining these lighting systems, rescue operations can be carried out even in low-light conditions.

[0053] Based on the above implementation scheme, a gas sensing component 7 is also installed on the outside of the supporting structure 1. The gas sensing component 7 can collect and report ambient gas. The gas sensing component 7 adopts a four-in-one gas detector, which can provide feedback alarms for toxic and harmful gases, such as carbon monoxide, hydrogen sulfide, and other combustible oxygen gases.

[0054] Based on the above implementation plan, as a further extension of the plan, an expansion device interface can be set on the lower bearing part 12 as a port reserved for the access of the vital signs monitoring module.
