Description

Technical Field

[0001] This invention relates to the field of life detection technology, and specifically to a life detection device. Background Technology

[0002] Life detection robots are specialized search and rescue robots designed for use in emergency situations such as earthquakes, explosions, landslides, and fires. They are primarily used to replace rescue personnel in searching for people in dangerous locations. Equipped with life detectors, life detection robots are small in size, which can reduce damage to the disaster site, prevent secondary injuries to victims, and allow them to navigate through narrow spaces inaccessible to rescue personnel.

[0003] However, the terrain at disaster sites is extremely complex, with various steep slopes, deep pits, and other terrains with large height spans. Conventional life detection robots usually move by tires or tracks, and the terrain height they can climb is limited, making it impossible for them to move to locations with large height spans. This greatly affects the rescue coverage area and reduces the quality of rescue efforts. Summary of the Invention

[0004] In view of the shortcomings of existing technologies, this invention proposes a life detection device to solve the problem that conventional life detection robots cannot move to locations with excessively large height spans.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] The present invention provides a life detection device, comprising:

[0007] The shell has a first power box at the bottom of its inner cavity, and tracks that are connected to the first power box are respectively provided on both sides of the shell. A second power box is provided inside the shell, and a propeller that extends above the shell is connected to the top of the second power box. A detector is provided on the shell.

[0008] A protective mechanism includes two protective plates symmetrically arranged on both sides of the outer surface of a housing. Each protective plate has a support at both ends, and a rotating shaft connects the two supports. The rotating shaft is rotatably mounted inside the housing.

[0009] The drive mechanism is capable of synchronously driving the two shafts to rotate in opposite directions, so that the two protective plates rotate above the propeller or to the bottom of the track.

[0010] Furthermore, the top of the housing is provided with a top opening that matches the size of the second power box, the second power box is slidably connected to the inner wall of the housing, and limit plates are respectively provided on both sides of the bottom of the second power box.

[0011] Furthermore, a first conductive sheet is provided on the top of one of the limiting plates, and a second conductive sheet is provided on the inner wall of the housing located directly above the first conductive sheet, and the second conductive sheet is connected to a power source.

[0012] Furthermore, the drive mechanism includes a drive motor, a first gear, and a rack. A sliding groove is provided on the top of the first power box. The rack is slidably installed in the sliding groove and located between two rotating shafts. One first gear is provided on each rotating shaft and is respectively connected to the rack for transmission. The drive motor is installed in the housing and located on one side of one of the rotating shafts. The motor shaft end of the drive motor is provided with a second gear that meshes with the first gear of the rotating shaft.

[0013] Furthermore, the top of the rack is connected to the bottom of the second power box.

[0014] Furthermore, each of the protective plates is rotatably connected to a buffer plate on the outer side of the end near the track. The end of the buffer plate away from the rotatable connection point is connected to the protective plate with a first airbag. The first airbag is provided with a conduit extending into the housing. The end of the conduit is connected to a second airbag. The second airbag is installed on the lower side of the inner wall of the housing directly above the limiting plate, and a rebound spring is provided inside the second airbag.

[0015] Furthermore, each of the protective plates is equipped with multiple auxiliary rollers at the end near the track.

[0016] As can be seen from the above technical solution, the present invention provides a life detection device:

[0017] 1. When the device needs to traverse terrain with large height spans, such as steep slopes and deep pits, and the tracks alone cannot achieve positional movement, the propeller can be driven to rotate through the second power box to lift the entire device, thereby enabling the device to successfully cross various terrains with large height spans, expanding the rescue coverage area and improving the quality of rescue.

[0018] 2. The second power box needs to be raised first so that the first conductive plate and the second conductive plate can make contact and be energized before the propeller can be started. This helps to prevent the propeller from being started when the tracked drive device is moving normally, which could cause misoperation.

[0019] 3. By rotating the two protective plates above the propeller, the propeller can be protected when it is not in use, preventing damage to the propeller when the device passes through narrow gaps or passages. Rotating the two protective plates below the tracks can protect the tracks when the device takes off, preventing damage to the tracks from violent impact with the ground when the device falls.

[0020] 4. By utilizing the drive mechanism, the state changes of multiple structures can be realized simultaneously. While driving the two protective plates to change position, the second power box can be driven to move up and down simultaneously, thereby realizing the power supply and disconnection of the second power box. It can also change the inflation state of the first airbag to provide further protection for the device. Attached Figure Description

[0029] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the invention; therefore, the invention is not limited to the specific embodiments disclosed below.

[0030] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0032] like Figure 1-3 As shown, the life detection device provided in this embodiment includes a housing 1, a protective mechanism 2, and a drive mechanism 3.

[0033] A first power box 11 is located at the bottom of the inner cavity of the housing 1. Tracks 12, which are driven and connected to the first power box 11, are respectively located on both sides of the housing 1. A second power box 13 is located inside the housing 1. A propeller 14 extending above the housing 1 is driven and connected to the top of the second power box 13. A detector 15 is installed on the housing 1. Motors are installed in the first power box 11 and the second power box 13, respectively, to drive the tracks 12 and the propeller 14, enabling the device to move via the tracks 12 and be lifted by the propeller 14. In practical use, when the device needs to traverse terrain with large height spans, such as steep slopes and deep pits, and the tracks 12 alone cannot achieve the required movement, the propeller 14 can be rotated by the second power box 13 to lift the entire device. This allows the device to successfully traverse various terrains with large height spans, expanding the rescue coverage area and improving the quality of rescue operations. It should be noted that the second power box 13 can not only drive the propeller 14 to rotate, but also adjust the propeller 14 or the tilt of the propeller blades to change the direction of travel of the device in the air. This adjustment structure can be referenced from existing technology products, such as toy helicopters, so it will not be described in detail here.

[0034] In one embodiment, the top of the housing 1 has a top opening 16 that matches the size of the second power box 13. The second power box 13 is slidably connected to the inner wall of the housing 1. By raising the second power box 13, the propeller 14 is raised, reducing the obstruction of the housing 1 on the propeller 14, thereby increasing the lift of the propeller 14 during rotation. Limiting plates 131 are respectively provided on both sides of the bottom of the second power box 13 to prevent the second power box 13 from detaching from the housing 1.

[0035] To prevent accidental activation of the propeller 14 while the track 12 is moving normally, a further feature is provided: a first conductive plate 132 is mounted on the top of one of the limiting plates 131. The first conductive plate 132 is electrically connected to the motor inside the second power box 13. A second conductive plate 133 is mounted on the inner wall of the housing 1 directly above the first conductive plate 132. The second conductive plate 133 is connected to a power supply 134, which can be a battery. In actual use, the second power box 13 must be raised first to allow the first conductive plate 132 and the second conductive plate 133 to contact and energize before the propeller 14 can be activated, thus helping to avoid accidental activation.

[0036] The protective mechanism 2 includes two protective plates 21, which are symmetrically arranged on both sides of the outer shell 1. Each end of the protective plate 21 has a bracket 22, and a rotating shaft 23 connects the two brackets 22. The rotating shaft 23 is rotatably installed inside the shell 1. By rotating the two protective plates 21 above the propeller 14, the propeller 14 can be protected when it is not in use, preventing damage to the propeller 14 when the device passes through narrow gaps or passages. Rotating the two protective plates 21 below the track 12 protects the track 12 during takeoff, preventing damage to the track 12 due to a violent impact with the ground when the device falls.

[0037] Preferably, each protective plate 21 is provided with multiple auxiliary rollers 215 at one end near the track 12. As the protective plate 21 rotates to the bottom of the track 12, the auxiliary rollers 215 can reduce friction and make the state switching of the protective plate 21 smoother.

[0038] The drive mechanism 3 can synchronously drive the two rotating shafts 23 to rotate in opposite directions, so that the two protective plates 21 rotate above the propeller 14 or to the bottom of the track 12.

[0039] In one embodiment, the drive mechanism 3 includes a drive motor 31, a first gear 32, and a rack 33. A sliding groove 111 is provided on the top of the first power box 11. The rack 33 is slidably mounted in the sliding groove 111 and located between two rotating shafts 23. One first gear 32 is provided on each rotating shaft 23 and is respectively connected to the rack 33 for transmission. The drive motor 31 is installed inside the housing 1 and located on one side of one of the rotating shafts 23. A second gear 34 is provided at the motor shaft end of the drive motor 31, meshing with the first gear 32 of that rotating shaft 23. In actual use, the drive motor 31 is started, and the second gear 34 meshes with the first gear 32 of one rotating shaft 23 to rotate. This first gear 32 then continues to drive the rack 33 to slide. The rack 33 located between the two first gears 32 will drive the other first gear 32 to rotate in the opposite direction to the previous first gear 32, so that the two rotating shafts 23 can rotate synchronously in opposite directions, thereby enabling the two protective plates 21 to rotate synchronously above the propeller 14 or below the track 12.

[0040] Furthermore, the top of the rack 33 is connected to the bottom of the second power box 13. It should be noted that when the second power box 13 is located inside the housing 1, the two protective plates 21 are positioned above the propeller 14 for protection. When the drive motor 31 drives the two protective plates 21 away from above the propeller 14, the rack 33 also rises under the drive motor 31, thereby raising the propeller 14 until the two protective plates 21 rotate to below the track 12, at which point the propeller 14 will rise to its highest point, completing the switching of the protective plate 21's usage state.

[0041] In one embodiment, each protective plate 21 has a buffer plate 211 rotatably connected to the outer side of its end near the track 12. A first airbag 212 is connected between the end of the buffer plate 211 away from the rotatable connection point and the protective plate 21. A conduit 213 extending into the housing 1 is provided on the first airbag 212. A second airbag 214 is connected to the end of the conduit 213. The second airbag 214 is installed on the lower side of the inner wall of the housing 1 directly above the limiting plate 131, and a rebound spring (not shown) is provided inside the second airbag 214. In actual use, when the protective plate 21 is above the propeller 14, the second power box 13 is located inside the housing 1. At this time, the limiting plate 131 will be away from the inner cavity top wall of the housing 1. The second airbag 214 is in an extended state under the action of the rebound spring, with gas concentrated inside the second airbag 214 and the first airbag 212 in a compressed state. When the propeller 14 needs to be rotated, under the action of the drive mechanism 3, the protective plate 21 rotates away from the top of the propeller 14 and gradually rotates to the bottom of the track 12. The second power box 13 is also lifted by the rack 33, and then the limiting plate 131 begins to squeeze the second airbag 214, so that gas is filled into the first airbag 212. After the first airbag 212 expands, the buffer plate 211 will be rotated and unfolded under force. During the period when the protective plate 21 is under the track 12, the buffer plate 211 will always maintain a certain distance from the protective plate 21. When the device needs to land after crossing high-span terrain with the help of the propeller 14, the first airbag 212 between the buffer plate 211 and the protective plate 21 will provide cushioning to absorb the vibration generated when the device lands and collides with the ground, preventing damage to the internal equipment of the device.

[0042] The life detection device provided by this invention, in practical use, when the device needs to traverse terrain with large height spans such as steep slopes and deep pits, and the track 12 alone cannot achieve positional movement, the drive motor 31 is activated to drive the two protective plates 21 to switch from above the propeller 14 to below the track 12. During the rotation of the protective plates 21, the second power box 13 is synchronously driven to move upward, so that the propeller 14 is raised. At the same time, the limiting plate 131 will squeeze the second airbag 214, so that gas is filled into the first airbag 212, providing buffering between the buffer plate 211 and the protective plate 21. When the switching is completed, the first conductive plate 132 and the second conductive plate 133 will make contact and be energized, so that the propeller 14 can be activated. After the propeller 14 is used up, the drive motor 31 is reversed to change the device's usage state again, so that it can continue to move using the track 12.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
