Description

Technical Field

[0001] This invention relates to the field of transportation technology, and in particular to a transfer stretcher door and a transportation vehicle. Background Technology

[0002] Rescue vehicles are mainly used in medical transport, rescue, and disaster relief missions, ensuring that patients are transferred to medical facilities as quickly as possible.

[0003] Most medical transport vehicles need to transport patients quickly, safely, and smoothly from the accident site to the nearest medical facility during medical rescue missions. However, traditional rescue transport vehicles typically require rescue personnel to carry the injured into and out of the vehicle's cargo compartment, a process that is inefficient and consequently leads to lower rescue efficiency. Therefore, solving the problem of rapidly moving patient stretchers into and out of the cargo compartment during transport will be one of the key technologies for transport vehicles to complete rescue missions. Summary of the Invention

[0004] The main objective of this invention is to provide a transfer stretcher door, which aims to improve the efficiency of transporting patients into and out of the transport vehicle.

[0005] To achieve the above objectives, the present invention proposes a transfer stretcher door for a transport vehicle, the transport vehicle having an entrance and exit, the transfer stretcher door comprising:

[0006] A hatch, which is rotatably located at the inlet / outlet; and

[0007] A stretcher is provided at the hatch, and the length direction of the stretcher is parallel to the width direction of the inlet and outlet.

[0008] Optionally, the hatch and the bottom of the inlet / outlet are rotatably connected, the hatch opens downwards by rotation, and the stretcher is rotatably mounted on the hatch.

[0009] Optionally, the stretcher has a pedal state and a stretcher state. In the pedal state, the hatch is open and the stretcher is parallel to the ground. In the stretcher state, the hatch is open or closed and the stretcher is parallel to the ground.

[0010] Optionally, the stretcher also has a stowed state, in which the stretcher is arranged parallel to the hatch and the stretcher is positioned close to the hatch.

[0011] Optionally, the transfer stretcher door further includes a locking device, which is located between the door and the stretcher.

[0012] Optionally, the locking device includes a locked state, a partially locked state, and an unlocked state;

[0013] In the locked state, the locking device locks the stretcher;

[0014] In the semi-locked state, the locking device provides torque to the stretcher to slow down the rotation speed of the stretcher;

[0015] In the unlocked state, the locking device unlocks the stretcher.

[0016] Optionally, the hatch is provided with a first mounting bracket, and the stretcher is rotatably connected to the first mounting bracket.

[0017] Optionally, there are two first mounting brackets, which are spaced apart along the width of the hatch. Each end of the stretcher is provided with a second mounting bracket, and each first mounting bracket is rotatably connected to a second mounting bracket.

[0018] Optionally, the first mounting bracket and / or the second mounting bracket are arranged in a triangular frame configuration.

[0019] Optionally, the outer edge of the apex corner of the first mounting bracket and / or the second mounting bracket is arc-shaped.

[0020] Optionally, the stretcher is plate-shaped; and / or

[0021] The stretcher is made of carbon fiber.

[0022] The present invention also proposes a transport vehicle, the transport vehicle including an inlet and outlet and the aforementioned transfer stretcher door, the transfer stretcher door being rotatably disposed at the inlet and outlet.

[0023] The aforementioned transfer stretcher door has at least the following beneficial effects:

[0024] The technical solution of this invention employs a transport vehicle, a hatch, and a stretcher. The transport vehicle has an entrance and exit; the hatch is rotatably located at the entrance and exit; the stretcher is located at the hatch, and the length direction of the stretcher is parallel to the width direction of the entrance and exit. Specifically, this solution places the stretcher on the cabin door, allowing patients to be transported into or out of the transport vehicle by opening and closing the door. Compared to the traditional method of manually carrying stretcher beds in and out of the transport vehicle, this saves time spent on stretcher transport and effectively provides rapid boarding and transfer for patients with mobility impairments who require stretcher immobilization. This reduces the labor costs for rescue personnel and improves transfer efficiency, thereby enhancing overall rescue efficiency. Furthermore, traditional stretchers are secured after being placed in the transport vehicle to prevent secondary injuries to patients caused by vehicle jolting during transport. This solution, by placing the stretcher directly on the cabin door, eliminates the need for securing the stretcher after it enters the transport vehicle, further saving time and improving rescue efficiency. Moreover, placing the stretcher directly on the cabin door reduces the unnecessary weight of both the door and the stretcher, saving space in the transport vehicle and effectively improving space utilization. It is evident that the technical solution of this invention can improve the efficiency of transporting patients into and out of the transport vehicle's cabin, thereby improving rescue efficiency.

[0034] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0036] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0037] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0038] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0039] This invention proposes a transfer stretcher door.

[0040] It should be noted that the present invention uses an aircraft as an example to illustrate the configuration of the transport vehicle 100. Of course, the transport vehicle 100 in this solution is not limited to an aircraft, but can also be a vehicle or other transport vehicle.

[0041] Furthermore, the term "parallel" in this application can be understood as parallel; for example, "parallel to the ground" as described below means parallel to the ground, and "parallel to the hatch" means parallel to the hatch. Of course, "parallel" in this application can also be understood as slightly inclined; for example, "parallel to the ground" as described below can also mean slightly inclined to the ground.

[0042] Reference Figure 1 and Figure 2 In one embodiment of the present invention, the transfer stretcher door is used for a transport vehicle 100, which is located at the entrance / exit 110. The transfer stretcher door includes a hatch 200 and a stretcher 300. The hatch 200 is rotatably located at the entrance / exit 110. The stretcher 300 is located at the hatch 200, and the length direction of the stretcher 300 is parallel to the width direction of the entrance / exit 110.

[0043] It should be noted that the parallelism between the length direction of the stretcher 300 and the width direction of the inlet / outlet 110 mentioned above refers to the parallelism between the length direction of the stretcher 300 and the width direction of the inlet / outlet 110.

[0044] Specifically, this solution places the stretcher 300 on the door 200, allowing patients to be transported into or out of the transport vehicle 100 by opening and closing the door 200. Compared to the traditional method of manually carrying stretcher beds in and out of the transport vehicle 100, this saves the time required for transporting the stretcher 300. It effectively provides rapid boarding and transfer for patients with mobility issues who require stretcher 300 immobilization, thereby reducing the labor costs for rescue personnel and improving transfer efficiency, ultimately enhancing rescue efficiency. Furthermore, traditional stretchers are secured after being placed in the transport vehicle. To prevent secondary injuries to patients due to bumps during transport, this solution directly places the stretcher 300 on the door 200, eliminating the need to secure the stretcher after it's inside the transport compartment, thus saving time and improving rescue efficiency. Furthermore, placing the stretcher 300 directly on the door 200 reduces the weight of both the door 200 and the stretcher 300 themselves, saving space in the transport compartment and effectively improving its space utilization. The length of the stretcher 300 is parallel to the width of the inlet / outlet 110, increasing the stability of its installation. Therefore, this invention improves the efficiency of transporting patients into and out of the transport compartment of the vehicle 100, thereby enhancing rescue efficiency.

[0045] Optionally, in this embodiment, the hatch 200 and the inlet / outlet 110 are rotatably connected at the bottom. The hatch 200 rotates downwards to open, and the stretcher 300 is rotatably mounted on the hatch 200. It can be understood that when the hatch 200 rotates downwards to open, the stretcher 300 will rotate relative to the hatch 200, always maintaining a parallel position with the ground. This ensures that when the patient is transported out of the transport cabin, the patient will also remain parallel to the ground. Similarly, when the hatch 200 rotates upwards to close, the stretcher 300 will also rotate relative to the hatch 200, always maintaining a parallel position with the ground. This ensures that when the patient is transported into the transport cabin, the patient will also remain parallel to the ground, thus preventing tilting and improving patient comfort. Of course, the invention is not limited to this. In other embodiments, the hatch 200 may also be rotatably connected to the side of the inlet / outlet 110, and the hatch 200 may rotate to open to the left or right.

[0046] Furthermore, when the hatch 200 rotates downwards and opens, the stretcher 300 will rotate relative to the hatch 200, maintaining a parallel position with the ground. At this time, the stretcher 300 can also serve as a footboard for rescue personnel. Traditional aircraft footboards are often designed to be compact to save weight and reduce drag, allowing only one person to enter or exit the transport cabin at a time. However, for rescue aircraft, efficiency in entering and exiting the cabin is particularly important. This design integrates the stretcher 300 and the footboard into a structural design, eliminating the need for traditional footboards. This saves space and improves space utilization. Moreover, the length of the stretcher 300 is sufficient to allow three people to enter and exit the transport cabin of the transfer stretcher door simultaneously, improving rescue efficiency during rescue missions. Traditional transfer stretcher doors have relatively simple boarding methods, often using external footboards, which also increase aerodynamic drag on the aircraft. This solution utilizes the stretcher 300 as a footboard, which can be folded into the transport cabin, without disrupting the aircraft's aerodynamic shape during flight. For aircraft with fixed-wing cruise capability, this solution can effectively reduce aerodynamic drag and thus lower energy consumption.

[0047] Reference Figures 2 to 6 Optionally, the stretcher 300 has a pedal state and a stretcher state. In the pedal state, the hatch 200 is open and the stretcher 300 is parallel to the ground. In the stretcher state, the hatch 200 is open or closed and the stretcher 300 is parallel to the ground. It can be understood that the pedal state allows the user to step in and out of the transport cabin, and the stretcher 300 is parallel to the ground in the stretcher state. Regardless of whether the hatch 200 is open or closed, the stretcher 300 can be used as a stretcher to fix the patient when it is necessary to fix the patient.

[0048] Optionally, the stretcher also has a folded state. In the folded state, the stretcher 300 is arranged parallel to the hatch 200, with the stretcher 300 positioned close to the hatch 200. The folded state allows for storage; that is, the stretcher 300 can be rotated, folded, and secured to the inner wall of the transfer stretcher door. This avoids the stretcher 300 occupying space in the transport compartment, increasing the effective internal loading space provided by the transfer stretcher door for other equipment and personnel. This improves the space utilization rate of the transport compartment.

[0049] The stretcher 300 has a pedal state, a stretcher state, and a storage state, which can improve the flexibility of the stretcher 300 and increase its functionality.

[0050] Furthermore, the transfer stretcher door also includes a locking device, which is located between the door 200 and the stretcher 300. It can be understood that setting a locking device between the door 200 and the stretcher 300 can lock the stretcher 300, increase the stability of the stretcher 300, prevent the stretcher 300 from shaking, and improve the comfort of the injured.

[0051] Furthermore, the locking device includes a locked state, a half-locked state, and an unlocked state; in the locked state, the locking device locks the stretcher 300; in the half-locked state, the locking device provides torque to the stretcher 300 to slow down the rotation speed of the stretcher 300; in the unlocked state, the locking device unlocks the stretcher 300. It can be understood that the locking device can quickly lock the stretcher 300, avoiding manual locking of the stretcher 300, thus improving the efficiency of unlocking and locking the stretcher 300, thereby increasing rescue efficiency. Moreover, the locking device has a half-locked state, which can provide torque to the stretcher 300 to prevent the stretcher 300 from rotating too fast, thereby improving the comfort of the injured.

[0052] Furthermore, when the stretcher 300 is in the pedal state and the storage state, the locking device is in the locked state; when the stretcher 300 is in the stretcher state, the locking device is in the semi-locked state; during the switching process of the stretcher 300 between the pedal state, the storage state and the stretcher state, the locking device is in the unlocked state.

[0053] It should be noted that when the stretcher 300 is in the footboard position, rescue personnel need to enter and exit the transport compartment. The stretcher 300 can be used as a footboard for rescue personnel to step on. The locking device locks the stretcher 300. At this time, the stretcher 300 is stationary relative to the compartment door 200. This can prevent the stretcher 300 from shaking when personnel step on it, thereby increasing safety and improving the efficiency of personnel entry and exit, and thus increasing rescue efficiency.

[0054] Furthermore, when the stretcher 300 is in the stowed state, the tightening device locks the stretcher 300, which can prevent the stretcher 300 from shaking during the operation of the transfer stretcher door and thus avoid accidentally injuring the personnel in the transport compartment. Moreover, the tightening device locks the stretcher 300 in the stowed state, which can prevent the stretcher 300 from occupying space in the transport compartment, thereby improving the space utilization rate of the transport compartment.

[0055] Furthermore, during the switching between the pedal state, the stowage state, and the stretcher state, the locking device of the stretcher 300 is in the unlocked state, meaning that the stretcher 300 can rotate freely relative to the cabin door 200. Since the stretcher 300 opens when the cabin door 200 rotates downwards or closes when it rotates upwards, the stretcher 300 can rotate freely relative to the cabin door 200 during the switching between the pedal state, the stowage state, and the stretcher state. The stretcher 300 always remains parallel to the ground. When the stretcher 300 is carrying a patient, this ensures that the patient remains parallel to the ground when being transported in and out of the transport cabin, preventing the patient from tilting and improving patient comfort.

[0056] Furthermore, when the stretcher 300 is in the stretcher position, the locking device is in a semi-locked state. That is, the locking device only provides torque to the stretcher 300 to slow down the rotation speed of the stretcher 300. In other words, when the stretcher door is being driven, the stretcher 300 is fixed to the injured person, and when the stretcher door is bumpy, the locking device provides a certain amount of damping to the stretcher 300, thereby reducing the swing amplitude of the stretcher 300, improving patient comfort, and preventing the stretcher 300 from rotating rapidly with the stretcher door.

[0057] Reference Figure 4 and Figure 6 Optionally, in this embodiment, the locking device is configured as a damping motor 400. The damping motor 400 ensures the stretcher 300 is stable and controllable during the closing and opening of the hatch 200, and reduces the rotational jolts felt by the injured person during driving, thus increasing the safety of the stretcher 300. Of course, the invention is not limited to this. In some other embodiments, the locking device can also lock a damping washer. When the stretcher 300 is in the pedal state and the stowed state, the buckle is used to lock the stretcher 300. When the stretcher 300 is in the stretcher state, the damping washer is placed between the hatch 200 and the stretcher 300, thereby slowing down the rotation speed of the stretcher 300. During the switching between the pedal state, the stowed state and the stretcher state, the buckle can be released, allowing the stretcher 300 to rotate freely relative to the hatch 200.

[0058] Optionally, the hatch 200 is provided with a plurality of first mounting brackets 210, and the stretcher 300 is rotatably connected to the first mounting brackets 210; the provision of the first mounting brackets 210 can facilitate the installation and arrangement of the stretcher 300.

[0059] Optionally, in this embodiment, two first mounting brackets 210 are provided, and the two first mounting brackets 210 are spaced apart along the width direction of the hatch 200. The two ends of the stretcher 300 are respectively rotatably connected to one of the first mounting brackets 210. It can be understood that fixing from both ends of the stretcher 300 can increase the stability of the stretcher 300 installation. Of course, the present invention is not limited to this. In other embodiments, there may be only one first mounting bracket 210, with the first mounting bracket located in the middle of the stretcher 300 and rotatably connected to the stretcher 300.

[0060] Optionally, in this embodiment, a second mounting bracket 310 is provided at each end of the stretcher 300, and a first mounting bracket 210 is rotatably connected to a second mounting bracket 310. This increases the operating space for the connection process of the first mounting bracket 210 of the stretcher 300, making it easier to install the stretcher 300. Of course, the present invention is not limited to this. In other embodiments, the two ends of the stretcher 300 can also be directly rotatably connected to the first mounting bracket 210.

[0061] Optionally, in this embodiment, the first mounting bracket 210 and / or the second mounting bracket 310 are arranged in a triangular frame configuration. It can be understood that, based on the principle of triangle stability, arranging the first mounting bracket 210 and / or the second mounting bracket 310 in a stretcher 300 frame configuration not only reduces weight but also increases the stability of the first mounting bracket 210 and the second mounting bracket 310, thereby increasing the stability of the stretcher 300. Of course, the invention is not limited to this; in other embodiments, the first mounting bracket 210 and / or the second mounting bracket 310 may also be arranged in a triangular panel configuration.

[0062] Furthermore, the first mounting bracket 210 and / or the second mounting bracket 310 are arranged in an isosceles triangular frame, which not only balances the forces on the first mounting bracket 210 and / or the second mounting bracket 310, but also helps to keep the stretcher 300 balanced.

[0063] Optionally, in this embodiment, the outer edges of the apex corners of the first mounting bracket 210 and / or the second mounting bracket 310 are arc-shaped. This increases safety and prevents the apex corners from scratching rescuers or patients.

[0064] Optionally, in this embodiment, the stretcher 300 is plate-shaped. It is understood that a traditional rescue stretcher 300 typically consists of a stretcher 300 body, sleds, pulleys, braking components, and a telescopic structure. If the aircraft uses a similar medical transport bed for transport, it would result in a significant weight penalty to the overall aircraft performance, and would occupy more space in the transport vehicle 100, hindering the care of patients by rescue personnel. This solution sets the stretcher 300 in a plate shape and connects it to the cabin door 200, eliminating the need for sleds, pulleys, and telescopic structures. This not only reduces the weight and space occupied by the stretcher 300 but also increases its reliability. Of course, the invention is not limited to this; in other embodiments, the stretcher 300 may also include a frame and a stretcher 300 fabric disposed on the frame.

[0065] Furthermore, the stretcher 300 can be equipped with quick-release railings, safety straps, telescopic bed boards, and other rescue functions, depending on its capabilities.

[0066] Optionally, in this embodiment, the stretcher 300 is made of carbon fiber. Firstly, carbon fiber is lightweight, reducing the weight of the stretcher 300. Secondly, carbon fiber has excellent energy absorption rate; its impact energy absorption capacity is six to seven times that of steel and three to four times that of aluminum, resulting in higher safety. Thirdly, carbon fiber has higher vibration damping; while light alloys require 9 seconds to stop vibration, carbon fiber composites stop vibration in 2 seconds, improving the comfort of the stretcher 300. Fourthly, carbon fiber has higher fatigue strength; the fatigue strength of steel and aluminum is 30-50% of their tensile strength, while carbon fiber can reach 70-80%, thus improving the reliability of the stretcher 300. Fifthly, carbon fiber is more designable than metals, making it easier to platformize, modularize, and integrate the stretcher 300's development. This allows the carbon fiber stretcher 300 to be modularized and integrated, significantly reducing the number of parts, tooling investment, and development cycle. Of course, the invention is not limited to this; in other embodiments, the stretcher 300 can also be made of plastic.

[0067] The present invention also proposes a transport vehicle, which includes a transfer stretcher door. The specific structure of the transfer stretcher door is as described in the above embodiments. Since the main transport vehicle adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The transfer stretcher door is rotatably located at the entrance / exit.

[0068] It should be noted that the means of transport is not limited to aircraft, but can also be vehicles or other means of transport.

[0069] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
