In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0051] Combine the following Figure 1-Figure 7 A multi-source sensor device according to an embodiment of the present invention is described.

[0052] An embodiment of a first aspect of the present invention provides a multi-source sensor device, Figure 1 One of the structural schematic diagrams of the multi-source sensor device provided by an embodiment of the present invention is illustrated. Figure 2 The second structural diagram of the multi-source sensor device provided by the embodiment of the present invention is illustrated. Figure 3 The third structural diagram of the multi-source sensor device provided by the embodiment of the present invention is illustrated as follows: Figures 1 to 3As shown, the multi-source sensor device 200 includes an integrated body 1, a multi-source sensor 2 and a protective mechanism 3. The multi-source sensor 2 is arranged on the integrated body 1. The protective mechanism 3 includes a driving component 31 and a protective part 32. The driving component 31 is connected to the integrated body 1 and the protective part 32 respectively. The driving component 31 is used to drive the protective part 32 to move so as to achieve shielding and removal of the multi-source sensor 2.

[0053] The multi-source sensor 2 is used to sense the surrounding environment information, and the multi-source sensor 2 includes at least one of a laser radar 21 , an infrared imager 22 , a camera 23 , and a blind spot radar 24 .

[0054] The driving component 31 drives the protective component 32 to move between a first position and a second position; in the first position, the protective component 32 is located on a side of the multi-source sensor 2 away from the integrated body 1 and blocks the multi-source sensor 2; in the second position, the protective component 32 moves away from a side of the multi-source sensor 2 away from the integrated body 1 to expose the multi-source sensor 2.

[0055] It is understandable that if Figure 2 As shown, the laser radar 21 is arranged on the integrated body 1. The laser radar 21 can obtain parameter information of the target, such as target distance, direction, height, speed, posture, and even shape parameters, so as to detect, track and identify the target.

[0056] The infrared imager 22 is arranged on the integrated body 1. The infrared imager 22 can adopt an infrared night vision device for observing long-distance targets, identifying targets, monitoring and reconnaissance, etc. It can be applied to tasks such as night combat, monitoring and reconnaissance.

[0057] The camera 23 is disposed on the integrated body 1 , and the camera 23 can obtain image information of a target and recognize the object based on the image information.

[0058] The blind spot radar 24 is arranged in the integrated body 1, and is used to make up for the difference in perception effect in the area outside the field of view of the laser radar 21, so as to effectively cope with complex working conditions.

[0059] It should be noted that one or more of the laser radar 21, the infrared imager 22, and the camera 23 can be integrated on the integrated body 1. When the laser radar 21, the infrared imager 22, the camera 23, and the blind spot radar 24 are integrated on the integrated body 1 at the same time, they can sense the existence of high-intensity electronic countermeasures and a large number of stealth targets through collaborative work, thereby meeting the multi-sensory needs of unmanned defense equipment.

[0060] It is understandable that if Figure 3As shown, the protective component 32 is in the first position, shielding the multi-source sensor 2 and having a certain front protection capability; when the multi-source sensor 2 needs to work, the driving component 31 drives the protective component 32 to move, so that the protective component 32 switches from the first position to the second position, as shown in FIG. Figure 2 As shown, at this time, the protective component 32 is removed to expose the multi-source sensor 2, and the multi-source sensor 2 senses the outside world.

[0061] It should be noted that the initial position of the protection component 32 can be at the first position to prevent the multi-source sensor 2 from being damaged by foreign objects during transportation, so as to increase the service life of the multi-source sensor 2.

[0062] The multi-source sensor device 200 provided in an embodiment of the present invention can obtain multi-sensory attribute parameters and facilitate management by integrating a laser radar 21, an infrared imager 22, a camera 23, and a blind spot radar 24 into an integrated body 1, and can meet the application of unmanned defense equipment in multiple environments; and, the driving component 31 drives the protective component 32 to move between a first position and a second position. When the multi-source sensor 2 is working normally, the protective component 32 is moved away from the side of the multi-source sensor 2 away from the integrated body 1, so that the multi-source sensor 2 is exposed for external perception. At this time, the protective component 32 is in the second position; when the multi-source sensor 2 needs to be protected, the protective component 32 is located on the side of the multi-source sensor 2 away from the integrated body 1 and blocks the multi-source sensor 2. At this time, the protective component 32 is in the first position to prevent foreign matter from splashing onto the sensor surface and affecting the perception ability of the multi-source sensor 2.

[0063] In one embodiment of the present invention, Figure 5 The schematic diagram of the cooperation between the integrated body and the protective component provided by the embodiment of the present invention is illustrated. Figure 6 The structural diagram of the protection mechanism provided by the embodiment of the present invention is illustrated as follows: Figure 5 and Figure 6 As shown, the driving assembly 31 includes a driving member 311 and a main rotating member 312 . The driving member 311 is disposed on the integrated body 1 . The main rotating member 312 is rotatably disposed on the integrated body 1 . The main rotating member 312 is connected to the driving member 311 and the protective member 32 , respectively.

[0064] It can be understood that the driving member 311 can be a driving motor arranged in the integrated body 1. The driving member 311 drives the main rotating component 312 to rotate, and the main rotating component 312 drives the protective component 32 to rotate, thereby realizing the rotation of the protective component 32 relative to the integrated body 1, thereby realizing the rotation of the protective component 32 relative to the multi-source sensor 2 on the integrated body 1, so as to achieve the shielding of the multi-source sensor 2 by the protective component 32.

[0065] In the embodiment of the present invention, the main rotating component 312 includes a rotating member 3121 , which is rotatably disposed on the integrated body 1 and connected to the driving member 311 , and the rotating member 3121 is connected to the protective component 32 .

[0066] It can be understood that the rotating member 3121 is installed on the integrated body 1 through a bearing, the rotating member 3121 is an annular rotating plate, the inner ring surface of the rotating member 3121 is connected to the driving member 311 through a transmission component, and the outer ring surface of the rotating member 3121 is connected to the protective component 32.

[0067] Furthermore, the main rotating component 312 also includes a telescopic component 3122 , and the rotating component 3121 is connected to the protective component 32 via the telescopic component 3122 , and the protective component 32 can be extended and retracted relative to the integrated body 1 via the telescopic component 3122 .

[0068] It can be understood that the driving member 311 drives the rotating member 3121 to rotate, thereby driving the protective member 32 to switch between the first position and the second position. When the protective member 32 is in the second position, the telescopic member 3122 is in a retracted state, and the protective member 32 moves away from the multi-source sensor 2 to expose the multi-source sensor 2. When the protective member 32 switches from the second position to the first position, the telescopic member 3122 extends, and then the driving member 311 drives the rotating member 3121 to rotate, driving the protective member 32 to rotate to the outside of the multi-source sensor 2 and cover the multi-source sensor 2. At this time, the protective member 32 is in the first position, the telescopic member 3122 is in an extended state, and the protective member 32 covers the multi-source sensor 2.

[0069] It is understandable that after the protective component 32 completes the protective task, when the protective component 32 switches from the first position to the second position, the driving member 311 first drives the rotating member 3121 to rotate in the opposite direction and return to its original position, and then the telescopic member 3122 retracts.

[0070] In the embodiment of the present invention, the transmission component includes a main transmission component and a slave transmission component that cooperate with each other. The main transmission component is arranged on the driving component 311, and the slave transmission component is arranged on the rotating component 3121.

[0071] It can be understood that the main transmission member is coaxially arranged on the output of the driving member 311, the slave transmission member is arranged on the inner ring surface of the rotating member 3121, and the slave transmission member is meshed with the main transmission member for transmission, then the driving member 311 drives the main transmission member to rotate synchronously, the main transmission member drives the slave transmission member to rotate, and the slave transmission member drives the rotating member 3121 to rotate synchronously.

[0072] It is understandable that the main transmission member and the driven member can adopt a gear transmission mode, then the main transmission member is a driving gear, and the driven member is a driven gear. Of course, the driven gear can be formed on the inner ring surface of the rotating member 3121, so that the inner ring surface of the rotating member 3121 has driven teeth meshing with the driving gear.

[0073] It should be noted that an intermediate transmission gear may be provided between the main transmission member and the slave transmission member to reduce the volume of the transmission components.

[0074] In one embodiment of the present invention, Figure 6 As shown, the driving assembly 31 also includes a secondary rotating component 313 , which is rotatably disposed on the integrated body 1 and connected to the protective component 32 .

[0075] It can be understood that in order to improve the rotation stability of the protective component 32, a slave rotating component 313 is also arranged between the integrated body 1 and the protective component 32, the main rotating component 312 and the slave rotating component 313 are coaxially spaced and connected to the protective component 32.

[0076] It can be understood that the driving member 311 drives the main rotating component 312 to rotate, and the main rotating component 312 and the slave rotating component 313 are connected via the protective component 32 , so that the slave rotating component 313 rotates synchronously with the main rotating component 312 .

[0077] It should be noted that the secondary rotating component 313 is located above the primary rotating component 312 . The secondary rotating component 313 has the same structure as the primary rotating component 312 , including a rotating component 3121 and a telescopic component 3122 , which will not be described in detail in this embodiment.

[0078] In the multi-source sensor device 200 provided by the embodiment of the present invention, a slave rotating component 313 is arranged between the integrated body 1 and the protective component 32 . The main rotating component 312 and the slave rotating component 313 rotate synchronously, thereby improving the stability of the rotation and extension of the protective component 32 .

[0079] In one embodiment of the present invention, the multi-source sensor device 200 also includes a washing and blowing mechanism (not shown in the figure), the washing and blowing mechanism includes a washing and blowing body and a washing and blowing pipeline, the washing and blowing body is arranged in the integrated body 1, the washing and blowing pipeline is connected to the washing and blowing body, and the outlet of the washing and blowing pipeline is used for washing and blowing the multi-source sensor 2.

[0080] It is understandable that when there are stains on the lens surface of the multi-source sensor 2, the cleaning and blowing mechanism is started to clean the multi-source sensor 2, and then blow-dried after cleaning, so as to better perceive the surrounding environment information.

[0081] Furthermore, the washing and blowing body includes a flushing component, an air-drying component and a switching valve. The air-drying component and the flushing component are arranged in the integrated body 1. The first end of the switching valve is connected to the flushing component, the second end of the switching valve is connected to the air-drying component, and the third end of the switching valve is connected to the inlet of the washing and blowing pipeline.

[0082] It can be understood that the flushing component includes a flushing liquid tank and a flushing machine, which is respectively connected to the flushing liquid tank and the first end of the switching valve, and is connected to the first end of the switching valve and the third end of the switching valve, and can clean the lens of the multi-source sensor 2 through the washing and blowing pipeline.

[0083] It can be understood that the air-drying component includes an air dryer, which is connected to the second end of the switching valve, connected to the second end of the switching valve and the third end of the switching valve, and can achieve air drying of the lens of the multi-source sensor 2 through a washing and blowing pipeline.

[0084] Among them, the first end of the switching valve is connected to the third end of the switching valve, and the switching valve is in a water circuit state; the second end of the switching valve is connected to the third end of the switching valve, and the switching valve is in a gas circuit state.

[0085] The multi-source sensor device 200 provided in the embodiment of the present invention cleans and dries the lens of the multi-source sensor 2 through a washing and blowing mechanism, so that the surface of the multi-source sensor 2 remains clean, thereby having automatic anti-fouling capability and meeting the application requirements of multiple environmental scenarios (deserts, forests, amphibians, etc.).

[0086] In one embodiment of the present invention, a flow channel connected to the outlet of the washing and blowing pipeline is constructed inside the protective component 32, and a nozzle 3221 connected to the flow channel is provided on one side of the protective component 32 close to the integrated body 1.

[0087] It can be understood that the lens of the multi-source sensor 2 is cleaned and dried by the nozzle 3221 provided on the protective component 32 .

[0088] It can be understood that when there are stains on the lens surface of the multi-source sensor 2, the flushing machine is started, the switching valve is switched to the water path state, and the cleaning medium of the flushing liquid tank passes through the washing and blowing pipe, the flow channel in the protective component 32, and the nozzle 3221 to flush the lens surface of the multi-source sensor 2; after flushing, the flushing machine is turned off, the air dryer is started, the switching valve is switched to the air path state, and the hot air of the air dryer passes through the washing and blowing pipe, the flow channel in the protective component 32, and the nozzle 3221 to dry the lens surface of the multi-source sensor 2.

[0089] In one embodiment of the present invention, Figure 7 The structural diagram of the protection component provided by the embodiment of the present invention is illustrated as follows: Figure 7 As shown, the protective component 32 is a hollow structure, which includes an outer protective plate 321 and an inner protective plate 322 that are connected. A cavity is formed between the outer protective plate 321 and the inner protective plate 322, and the cavity serves as a flow channel. The inner protective plate 322 is provided with a nozzle 3221 that is connected to the cavity.

[0090] In the embodiment of the present invention, a connecting pipe 3222 communicating with the cavity is provided on the inner protection plate 322 , and the connecting pipe 3222 is communicated with the outlet of the washing and blowing pipeline.

[0091] Furthermore, the washing and blowing pipeline has a water-gas rotating joint to prevent the washing and blowing pipeline from rotating and being damaged during the rotation of the protection component 32. The water-gas rotating joint can be a 360° water-gas rotating joint.

[0092] It should be noted that a circular hole is opened on the rotating plate of the rotating component 313, and the protective component 32 is connected to the rotary joint through a connecting pipe 3222 passing through the circular hole, and then connected to the washing and blowing body to form a rotating protective mechanism.

[0093] In one embodiment of the present invention, Figure 4 The fourth structural diagram of the multi-source sensor device provided by the embodiment of the present invention is illustrated as follows: Figure 4 As shown, the integrated body 1 includes an upper seat 11, a middle seat 12, a lower seat 13, and a bottom plate 14 which are arranged in sequence from top to bottom, and the rotating member 3121 of the main rotating component 312 is arranged between the lower seat 13 and the middle seat 12 through a bearing, and the rotating member 3121 of the secondary rotating component 313 is arranged between the middle seat 12 and the upper seat 11 through a bearing.

[0094] Furthermore, the multi-source sensor 2 includes a laser radar 21, an infrared imager 22, a camera 23 and a blind spot radar 24 arranged in sequence from top to bottom; in this embodiment, Figure 2 As shown, the infrared imager 22 adopts an infrared night vision device, the camera 23 adopts a camera module, the laser radar 21 is arranged on the upper seat 11, the infrared imager 22 and the camera 23 are arranged on the side wall of the middle seat 12, and the infrared imager 22 is located above the camera 23, and the blind spot radar 24 is arranged on the side wall of the lower seat 13.

[0095] It should be noted that the laser radar 21 is "standing high and seeing far", which can expand the detection distance within the limited range of the pitch angle of the laser radar 21, and is arranged on the upper seat 11 at the top of the integrated body 1. The blind spot radar 24 is mainly used to solve the problem of lateral blind spots and special-shaped target detection, making up for the difference in perception effects in areas outside the field of view of the laser radar 21, and can effectively deal with jamming and lane changes, and effectively deal with complex working conditions. It is arranged on the side wall of the lower seat 13 at the bottom of the integrated body 1. The infrared imager 22 is used in environments such as total darkness, weak light, and glare, and is suitable for severe weather such as sandstorms and haze days, to help safe driving all day long. Combined with the sensor module structure and the field of view of the infrared imager 22 and other factors, it is arranged on the side wall of the middle seat 12 below the laser radar 21. The camera 23 completes the driving perception task by detecting, identifying and understanding the external environment. Combined with the sensor module structure and the field of view of the camera 23 and other factors, it is arranged below the infrared imager 22. The camera 23 is a passive light-sensing device, which is very sensitive to light. The camera 23 is located close to the infrared imager 22 to form complementary advantages.

[0096] The multi-source sensor device 200 provided in an embodiment of the present invention integrates a laser radar 21, an infrared imager 22, a camera 23, and a blind spot radar 24 side by side from top to bottom in an integrated body 1.

[0108] It should be noted that the existing unmanned vehicle sensors are installed in a scattered manner and are difficult to manage in a unified manner. In addition, in harsh combat environments (sandy, muddy, watery, etc.), foreign objects are easily splashed onto the sensor surface, affecting the sensor's perception of the external environment, further affecting the execution of tasks. At the same time, when the unmanned vehicle is in combat, the shock wave generated by shooting will impact the sensor, affecting the service life of the sensor, and even exposed and unprotected sensors are easily hit and fail, making it impossible to complete subsequent tasks. The unmanned defense equipment provided by the embodiment of the present invention has a high degree of integration and can meet multi-sensing requirements by adopting a multi-source sensor device 200 that integrates a laser radar 21, an infrared imager 22, a camera 23, and a blind spot radar 24; in addition, the protection mechanism 3 resists the impact of foreign objects, thereby having protection capabilities to increase the service life.

[0109] The unmanned defense equipment provided by the embodiment of the present invention integrates the laser radar 21, infrared night vision device, camera module, blind spot radar 24, washing and blowing mechanism and protection mechanism 3 into the integrated body 1, and the multi-source sensor device 200 has the ability of anti-fouling, anti-impact and anti-ballistic. It can meet the application of unmanned defense equipment in multiple environments (desert, forest, amphibious, etc.) and has strong engineering applicability.

[0110] It should be noted that when the unmanned defense equipment provided by the embodiment of the present invention is driving in a harsh environment, if stains stick to the lens surface of the multi-source sensor 2, the lens can be cleaned and dried at any time through the washing and blowing mechanism, thereby reducing the impact of the environment on the unmanned defense equipment.

[0111] The unmanned defense equipment provided in the embodiment of the present invention can integrate all sensors in front of the vehicle into one by integrating the laser radar 21, infrared imager 22, camera 23, and blind spot radar 24 side by side from top to bottom in the integrated body 1, so as to facilitate management and data fusion and meet the driving perception requirements during the driving process of the unmanned defense equipment.
