Fig. 1 shows a schematic structural diagram of two open states of a housing of a fixed node robot according to an embodiment of the present disclosure, fig. 2 shows a schematic structural diagram of two open states of a protective housing of a fixed node robot according to an embodiment of the present disclosure, and fig. 3 shows a schematic structural diagram of a housing assembly of a fixed node robot according to an embodiment of the present disclosure.

As shown in fig. 1, the housing assembly of the fixed node robot includes two housings 10 which are snap-connected and can be opened. The housing 10 may be made of nylon or glass fiber, and the impact resistance of the housing 10 may be enhanced by using the material, so as to effectively protect the modules inside the housing 10 from being damaged, thereby protecting the modules inside the housing 10 from working normally. The outer surface of the shell 10 (or the exposed part of the shell 10) can be sprayed with flame-retardant heat-insulating paint, so that the exposed part of the shell 10 has flame-retardant heat-insulating effect, and the fixed node type robot arranged in a fire scene can work normally.

One side of the two housings 10 is hinged, an elastic member is disposed at the hinge of the two housings 10, for example, a rotating shaft 11 may be disposed at one side of the two housings 10, the two housings 10 may be rotatably disposed on the rotating shaft 11, a first torsion spring 12 is sleeved on the rotating shaft 11, one leg of the first torsion spring 12 abuts against one housing 10, the other leg abuts against the other housing 10, when the housings 10 are fastened, the first torsion spring 12 is in a compressed state, and at this time, the first torsion spring 12 provides an opening elastic force for the two housings 10.

The other side of the two housings 10 may be provided with locking means for locking. When the locking device is locked, the two shells 10 are in a buckling state; when the locking device is opened, the elastic force provided by the first torsion spring 12 may open the two housings 10. The specific structure of the locking device is described in the following embodiments.

In some application scenarios, when a fire disaster occurs, the fixed node type robot needs to be arranged to a fire scene in a throwing mode (for example, manual throwing can be adopted, and a throwing device can also be adopted for throwing), when the fixed node type robot is thrown, the angle of the fixed node type robot when the fixed node type robot falls to the ground is uncontrollable, for example, one side provided with a locking device is possibly contacted with the ground, at the moment, the front face of the locking device can face the bottom face after the locking device is opened, and therefore the required video information of the fire scene cannot be acquired.

Therefore, the outer surface of the shell 10 can be set to be an arc-shaped surface, that is, the cross section of the two shells 10 is in an eggshell-like shape (for example, an oval shape or a circular shape) when the two shells 10 are locked by the locking device, and by adopting the design mode, the back surface of one of the shells 10 is in contact with the ground finally under the adjustment of the self gravity no matter which surface the shell assembly is in contact with the ground after falling to the ground, so that the front surface of the shell assembly can face upwards after the shell assembly is bounced off under the action of the first torsion spring 12.

An audio and video bin 13 is arranged in one of the shells 10 close to one end, and a main control board bin 14 is arranged in the other end; a communication compartment 15 is provided in the other housing 10 near one end and a battery compartment 16 is provided near the other end.

As shown in fig. 2 and 3, a protective case 20 is coated on an outer surface of the case 10, and the protective case 20 has a buffer portion 21 at a front end of the case 10, the buffer portion 21 having a honeycomb structure and having a width (B direction in fig. 2) and a height (H direction in fig. 2) that are gradually reduced from the rear to the front (i.e., the rear end of the case 10 toward the front end).

The buffer portion 21 may be provided not only at the front end of the housing 10 but also at the rear end of the housing 10, and the buffer portions 21 may be provided even at both ends of the housing 10.

When the two housings 10 are fastened to each other, the two buffer portions 21 are fastened to each other to form a bullet shape. The buffer part 21 is in a bullet head shape, the cross section of the shell 10 behind the buffer part 21 is in an eggshell-like shape, so that the whole fixed node type robot is streamline, when the fixed node type robot is thrown, the frictional resistance of air can be reduced, meanwhile, the fixed node type robot can fly according to a preset track, and when the fixed node type robot lands on the ground, the buffer part 21 can be guaranteed to land on the ground firstly, and the huge impact force generated by collision between the fixed node type robot and the ground can be buffered.

In order to further ensure the flight path of the fixed node type robot in the air, the gravity center of the fixed node type robot can be controlled through the arrangement position of each module in the fixed node type robot. Specifically, in one housing 10, the audio/video cabinet 13 may be disposed at one end of the housing 10 close to the buffer portion 21, and the main control board cabinet 14 may be disposed at one end of the housing 10 far from the buffer portion 21; in another housing 10, the communication chamber 15 may be disposed at an end of the housing 10 close to the buffer portion 21, and the battery chamber 16 may be disposed at an end of the housing 10 far from the buffer portion 21.

Fig. 4 shows a schematic structural diagram of an operating state of a fixed node robot according to an embodiment of the present disclosure, and fig. 5 shows a schematic structural diagram of an operating state of a fixed node robot according to another embodiment of the present disclosure.

As shown in fig. 4, in one of the housings 10, an audio/video control board 33 may be fixedly mounted in the audio/video compartment 13 through bolts, and a speaker may be fixedly mounted on an upper surface of the audio/video control board 33 through a speaker gland; the main control board 34 may be fixedly mounted in the main control board chamber 14 through bolts, and a voice sensor (e.g., a microphone) may be fixedly mounted on one side of the main control board 34. An antenna assembly 32 can be fixedly arranged between the audio and video cabin 13 and the main control board cabin 14 through bolts. The antenna assembly 32 may be a 580MHz antenna.

For example, voice communication with the people trapped in the fire scene may be performed through the speaker, the microphone, and the antenna assembly 32, and sound information of the fire scene may be collected and transmitted through the microphone and the antenna assembly 32.

In the other shell 10, a communication module 36 can be fixedly arranged in the communication cabin 15 through bolts; the battery compartment 16 may be fixedly mounted with a battery 35 therein by bolts.

A gas sensor may also be provided within either housing 10 and connected to the antenna assembly 32 to enable information such as gas concentration at the fire site to be collected and transmitted.

It should be noted that, by arranging the antenna assembly 32, the audio/video control board 33, the main control board 34, the battery 35 and the communication module 36 in the housing 10, the center of gravity of the fixed node type robot can also be adjusted, so that the fixed node type robot can be thrown and laid according to a predetermined flight trajectory.

As shown in fig. 5, in order to protect the audio/video control board 33, the main control board 34, the communication module 36 and the battery 35, cover plates may be respectively disposed on the audio/video bin 13, the main control board bin 14, the communication bin 15 and the battery bin 16, and high temperature resistant sealing rings may be disposed at the connection portions of the cover plates and the respective bins. The cover plate can be sprayed with flame-retardant heat-insulating paint.

With continued reference to fig. 4 and 5, a camera assembly 31 is disposed at a position of one of the shells 10 close to the protection shell 20, and the camera assembly 31 can be pressed against an accommodating cavity formed by the two shells 10 when the two shells 10 are buckled, and can also be bounced to a working state when the two shells 10 are opened to collect video information of a fire scene, so that portable deployment in the fire scene can be realized.

Therefore, when the camera assembly 31 is in a non-working state (i.e., the housing 10 is in a locked state), the camera assembly 31 can be pressed against the accommodating cavity formed by the two housings 10, so that the camera assembly 31 is prevented from being damaged by external force, and when the camera assembly is in a working state (i.e., the housing 10 is in an opened state), the camera assembly bounces, so that video information of a fire scene can be collected.

It should be noted that the camera assembly 31 is in an operating state of being flipped up to form a certain angle with a plane where the upper surface of any one of the housings 10 is located, and the video information of the fire scene can be collected at the angle. For example, camera assembly 31 may be flipped up to an angle of 30 °, 60 °, or 90 ° to the plane in which the upper surface of either housing 10 lies. Preferably, after the camera assembly 31 is bounced to the working state, the extending direction of the camera assembly 31 is perpendicular to the plane where the upper surface of any one of the housings 10 is located, that is, the camera assembly 31 is bounced to form an angle of 90 ° with the plane where the upper surface of any one of the housings 10 is located.

In order to ensure that the camera assembly 31 forms an included angle of 90 degrees with the plane where the upper surface of the housing 10 is located when the camera assembly is in a working state, the camera assembly can be installed and fixed in a limiting manner.

Specifically, referring to fig. 6, the camera head assembly 31 includes a bracket 311, a second torsion spring 312, a stopper 313, two 180 ° cameras 314, and an antenna (not shown in the figure). The bracket 311 is long, the two 180-degree cameras 314 are oppositely arranged at one end of the bracket 311 so as to be capable of acquiring video information in front and back directions when the camera assembly 31 is in a working state, the other end of the bracket 311 is hinged to the casing 10, the second torsion spring 312 is arranged at the hinged position, and the limiting member 313 is arranged on the casing 10 and used for limiting the bouncing angle of the camera assembly 31.

More specifically, one leg of the second torsion spring 312 abuts against the housing 10, and the other leg abuts against one side of the bracket 311, that is, two legs of the second torsion spring 312 are located inside an included angle of a plane where the camera head assembly 31 and the upper surface of the housing 10 are located. The position limiting member 313 includes a base 3131 and a baffle 3132, the base 3131 is disposed in the housing 10, the baffle 3132 is connected to the base 3131, and the baffle 3132 has a predetermined inclination angle with respect to the plane where the upper surface of the housing is located, where the angle may be 45 °, so as to ensure that the camera assembly 31 is limited by the baffle 3132 after being popped up, and forms a 90 ° included angle with the plane where the upper surface of the housing 10 is located after being popped up.
