[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0038] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" can / explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0039] like Figures 1 to 4As shown, the utility model provides a rescue robot 100, comprising a robot body 1, a moving assembly 2, a support platform 3 and a stretcher 4. The moving assembly 2 is installed at the lower part of the robot body 1 to drive the robot body 1 to move. The support platform 3 is arranged at the upper part of the robot body 1 and has an upward and downward movable stroke relative to the robot body 1. The stretcher 4 is detachably arranged on the upper side of the support platform 3 so that the stretcher 4 can be separated from the support platform 3.

[0040] The technical solution of the utility model is to set a support platform 3 that can move up and down, so that the height of the stretcher 4 located above the support platform 3 can be adjusted, so that when the patient is transferred to the ambulance, there is no need to manually adjust the height of the patient. In addition, the stretcher 4 can be separated from the support platform 3, but after the patient is lifted to the required height, the stretcher 4 can be moved directly to avoid direct movement of the patient, reduce the impact on the patient, and improve the rescue efficiency.

[0041] It is understandable that the mobile component 2 can adopt a track mechanism or a wheel mechanism. The wheel mechanism: uses wheels to move, has a simple structure, high maneuverability, smooth movement, high efficiency, and easy operation. The track mechanism: uses multiple belt-shaped tires for driving, and can travel on uneven or obstructed ground. Due to its strong passing ability, the track mechanism is often used in mobile robots that need to operate in complex terrain.

[0042] In one embodiment, the support platform 3 can be arranged to move up and down so that the support platform 3 has an up and down movable stroke relative to the robot body 1; the rescue robot also includes a lifting component 5, which is installed between the robot body 1 and the support platform 3 to drive the support platform 3 to move up and down.

[0043] It can be understood that the lifting component 5 is set to drive the support platform 3 to move up and down, so that the stretcher 4 located on the support platform 3 is lifted and lowered to adjust the distance between the patient and the ambulance. Specifically, in this embodiment, the lifting component 5 includes an electric telescopic rod, the bottom of the electric telescopic rod is installed on the robot body 1, and the telescopic end thereof is installed at the lower part of the support platform 3. The lifting and lowering of the support platform 3 is adjusted by changing the extension and retraction of the telescopic end.

[0044] In one embodiment, at least two lifting assemblies 5 are provided, and at least two lifting assemblies 5 are symmetrically arranged at the lower part of the support platform 3 .

[0045] It can be understood that by providing at least two lifting components 5, the pressure received by a single lifting component 5 can be dispersed, and the symmetrical arrangement can enable the support platform 3 to maintain smooth movement during the lifting process.

[0046] In one embodiment, a sliding portion 41 is disposed on the lower side of the stretcher 4 , and a sliding groove 31 is provided on the upper portion of the support platform 3 , and the sliding groove 31 allows the sliding portion 41 to slide on the support platform 3 .

[0047] It is understandable that the sliding part 41 can be a wheel, a roller or other types of sliding mechanisms, which enable the stretcher 4 to move smoothly on the ground or other planes, reducing the bumps and discomfort to the patient. The design of the sliding groove 31 ensures that the sliding part 41 can be stably maintained in the correct position, and will not fall off or shift even during the movement, thereby reducing the impact on the patient and improving the quality of rescue.

[0048] In one embodiment, a handle 42 is further provided on the circumference of the stretcher 4 .

[0049] It is understandable that multiple handles 42 can be set on the sides of the stretcher 4. In this way, the sliding part 41 can be pushed by the handles 42 to slide in the sliding groove 31. At the same time, the handles 42 are also convenient for rescue personnel to grasp, lift or transport, increase the force points, and will not affect the patient on the stretcher 4.

[0050] In one embodiment, the rescue robot 100 further includes a locking assembly 6, which includes a connecting portion 61 and a locking portion 62. The connecting portion 61 is mounted on one side of the stretcher 4, and the locking portion 62 is connected to the support platform 3 at a position corresponding to the connecting portion 61. The locking portion 62 has a movable stroke relative to the connecting portion 61, and the locking portion 62 can move between a locking position and a release position during the movable stroke; wherein, in the locking position, the connecting portion 61 is locked by the locking portion 62, so that the stretcher 4 can be connected to the support platform 3; and in the release position, the connecting portion 61 is released by the locking portion 62, so that the stretcher 4 can be separated from the support platform 3.

[0051] It is understandable that the locking assembly 6 is to ensure that when the rescue robot 100 carries the stretcher 4, the stretcher 4 can be firmly connected to the support platform 3 of the robot to prevent accidental detachment in complex terrain or when performing tasks, and can be quickly released when the stretcher 4 needs to be removed. When the locking portion 62 is in the locked position, it fastens the connecting portion 61 through a mechanical device (such as a buckle, bolt, pin or hydraulic / pneumatic system), thereby firmly locking the stretcher 4 on the support platform 3. This can ensure the stability of the stretcher 4 during transportation. When the stretcher 4 needs to be removed from the support platform 3, the operator will move the locking portion 62 to the release position. In this position, the locking mechanism will be released or withdrawn, and the connecting portion 61 will be released, so that the stretcher 4 can be smoothly removed from the support platform 3.

[0052] In one embodiment, the locking assembly 6 further includes a fixing portion 63, which is connected to the support platform 3 to form a first slot 611, and the end of the connecting portion 61 away from the stretcher 4 is connected to the fixing portion 63, and a second slot 631 is formed; wherein the first slot 611 is connected to the second slot 631 to constitute a movable stroke of the locking portion 62, the locking portion 62 is located in the first slot 611 to constitute a release position, and the locking portion 62 is located in the second slot 631 to constitute a locking position.

[0053] In this way, the first slot 611 and the second slot 631 provide guidance for the movement of the locking part 62, ensuring that it can accurately move to the predetermined position, so that the movable range of the locking part 62 is limited, and its freedom of movement is reduced, so that the locking part 62 can work normally in the face of vibration and impact, thereby improving the locking reliability of the locking part 62.

[0054] In one embodiment, the locking assembly 6 further comprises an elastic member 64 , one end of which is connected to the fixing portion 63 , and the other end of which is connected to the locking portion 62 , and which is loaded with a tensile force to drive the locking portion 62 to remain in the locking position.

[0055] It is understandable that when the locking portion 62 is in the unlocked position, i.e., in the first slot 611, the elastic member 64 is stretched due to its own tension. In this stretched state, the elastic member 64 attempts to pull the locking portion 62 back to its original position, i.e., the locked position in the second slot 631. Therefore, the tension of the elastic member 64 actually helps drive the locking portion 62 to overcome any external resistance, thereby ensuring that the locking portion 62 is reliably locked in the second slot 631.

[0056] When the locking portion 62 needs to be released, the operator will pull the locking portion 62 out of the second slot 631 through manual operation or automatic mechanism, so that it enters the unlocking position in the first slot 611. At this time, since the locking portion 62 has left the second slot 631, the connecting portion 61 is released by the locking portion 62 and can be separated from the fixing portion 63. The addition of the elastic member 64 not only enhances the stability of the locking mechanism, but also provides a self-locking function when the locking mechanism fails, ensuring that the stretcher 4 will not accidentally fall off under any circumstances.

[0057] In one embodiment, the locking assembly 6 also has a limiting rail 65 and a limiting slider 66. The limiting rail 65 is installed on the support platform 3, and its extension direction is the same as the tension loaded by the elastic member 64. One end of the limiting slider 66 is connected to the limiting rail 65 and slides along the extension direction of the limiting rail 65, and the other end is connected to the locking portion 62. The lower side of the limiting slider 66 is connected to the end of the elastic member 64 away from the fixed portion 63, so that the limiting slider 66 is subjected to the tension loaded by the elastic member 64 and slides along the limiting rail 65 toward the fixed portion 63 until the locking portion 62 moves in the same direction to the locked position and stops.

[0058] It is understandable that the limiting track 65 plays a guiding and positioning role, and it provides a path for the limiting slider 66 to move along its own extension direction. The limiting slider 66 is used to ensure that the locking portion 62 can accurately move in its active stroke. When the limiting slider 66 slides along the limiting track 65 in the direction of the fixed portion 63, it will receive an external force to load its elastic member 64 with a tensile force, so that the locking portion 62 is located in the release position. When the limiting slider 66 slides along the limiting track 65 in the direction of the fixed portion 63, it will be subjected to the tensile force of the elastic member 64, so that the locking portion 62 is located in the locked position. When the locking portion 62 reaches the locked position, the limiting slider 66 is maintained in that position due to the continuous stretching action of the elastic member 64, thus ensuring that the locking portion 62 is firmly fixed in place until a release command is received to disengage it from the locked position. Through this mechanism, not only the reliability and stability of the locking portion are enhanced, but also the accuracy and repeatability of the operation are ensured.

[0059] In one embodiment, the rescue robot 100 further includes a storage box disposed on the robot body 1 , through which materials needed for rescue can be placed.

[0060] In one embodiment, the rescue robot 100 also includes a control system 7 disposed on the robot body 1. The control system 7 has a controller 71 and a signal receiver 72. The signal receiver is used to receive external instructions and transmit them to the controller 71, and the controller 71 drives the moving component 2 to move.

[0061] It can be understood that the signal receiver 72 receives external instructions and transmits the signal to the controller 71, and the controller 71 controls the movement of the mobile component 2, so that the rescue robot 100 can move intelligently and automatically, thereby improving the efficiency of rescue.

[0062] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention.
