Description

Technical Field

[0001] This invention relates to the field of robotic dog technology, and more particularly to a border patrol robotic dog. Background Technology

[0002] Border patrol robot dogs are a product of the combination of bionic robot technology and security needs. Traditional border patrols rely on manpower and fixed monitoring, which is inefficient and easily limited by terrain. There is an urgent need for mobility and intelligence. Therefore, border patrol robot dogs have emerged. Equipped with modules such as radar, cameras, and jamming guns, they have the functions of autonomous patrol, target detection and interception.

[0003] In existing technologies, robotic dogs used for border patrols typically have precision instruments such as radar, cameras, and jamming guns fixed to their surface. When not engaging (tracking) targets, this makes them less maneuverable in areas with obstacles such as bushes, and the instruments are easily damaged. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a border patrol robot dog.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A border patrol robot dog includes: a robot dog body and an outer casing. The outer casing has a first cavity extending through the top of the outer casing. Inside the outer casing is an instrument platform that can be driven to flip at the opening of the first cavity. Precision instruments for tracking targets are mounted on the surface of the instrument platform. A bracket is fixedly installed at the bottom of the first cavity. An inner casing that slides up and down along the surface of the first cavity is provided between the bracket and the instrument platform. An elastic element is provided between the inner casing and the bracket. The inner casing has a second cavity extending through the top of the inner casing. Under the elastic force of the elastic element, the inner casing abuts against the instrument platform and covers the instrument inside the second cavity.

[0006] Preferably, the inner box and the bracket are provided with a push-button latch, and the elastic element is provided with multiple springs, with the two ends of the springs being fixedly installed to the bottom of the inner box and the top of the bracket, respectively.

[0007] Preferably, the top edge of the inner box has two symmetrically shaped inclined surfaces, a main shaft runs through the inside of the instrument platform, the main shaft is fixedly installed with the instrument platform, the two ends of the main shaft extend out from opposite sides of the instrument platform, and the ends of the main shaft are connected to the device inside the robot dog body that drives its rotation.

[0008] Preferably, the instrument platform is detachably and fixedly installed with elastic protrusions on both opposite sides, and both elastic protrusions are formed in an arc shape on the side near the outer casing.

[0009] Preferably, an anti-loosening mechanism is provided between the inner box and the bracket, which is used to prevent the push-button lock from being accidentally unlocked.

[0010] Preferably, the anti-loosening mechanism includes a first shaft and a second shaft. When the instrument platform is rotated 180 degrees to place the instrument in the external environment, the bottom end of the first shaft abuts against the top end of the second shaft, at which time the inner box and the support form a whole.

[0011] Preferably, there are multiple first shafts, each of which is disposed inside a plurality of springs and is fixedly installed to the bottom of the inner housing. There are also multiple second shafts, and the surface of the bracket has multiple through holes adapted to the second shafts. The multiple second shafts are slidably installed in the corresponding through holes.

[0012] Preferably, the bracket has a downward-facing U-shaped structure, and a transmission mechanism for driving the second shaft to slide within the through hole is provided between the bracket and the bottom of the first cavity.

[0013] Preferably, the transmission mechanism includes a driving chain, a chain, a driven chain, and a third shaft. The surface of the third shaft is provided with external threads. The third shaft is rotatably connected to the bracket. One end of the third shaft passes through the outer surface of the outer housing and is fixedly installed at the rotation center of the driven chain. The driving chain is fixedly sleeved on the surface of the main shaft. After the chain is tightened, it is sleeved between the driving chain and the driven chain.

[0014] Preferably, the transmission mechanism further includes a slider, a rack, multiple gears, and multiple fourth shafts. One end of each of the multiple fourth shafts is fixedly installed to the rotation center of the multiple gears. Each of the fourth shafts also has an external thread on its surface. The multiple fourth shafts are inserted into the interior of the multiple second shafts from the bottom end and are threadedly connected to them. The multiple gears are rotatably connected to the bottom of the first cavity. The rack is slidably installed in the bottom of the first cavity and simultaneously meshes with the multiple gears. The slider is also slidably installed in the bottom of the first cavity and fixedly installed to one end of the rack. One end of the third shaft passes through the outer surface of the slider and is threadedly connected to it.

[0015] By combining an outer casing and an inner casing to protect the instrument, the outer casing provides direct contact protection, such as impact (or even bulletproof), while the inner casing provides non-contact protection (such as ultrasonic attacks). This two-layer protection effectively prevents the instrument used to track (attack) targets from being damaged during patrols, thus extending the lifespan of the device. Attached Figure Description

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] Reference Figure 1 A border patrol robot dog includes: a robot dog body 100 and an outer casing 200. The outer casing 200 has a first cavity that extends through the top of the outer casing 200. Inside the outer casing 200 is an instrument platform 300 that can be driven to flip at the opening of the first cavity. The surface of the instrument platform 300 is equipped with precision instruments (radar, camera, jamming gun, etc.) for tracking targets. A bracket 220 is fixedly installed at the bottom of the first cavity. Between the bracket 220 and the instrument platform 300 is an inner casing 210 that slides up and down along the surface of the first cavity. An elastic element 230 is provided between the inner casing 210 and the bracket 220. The inner casing 210 has a second cavity that extends through the top of the inner casing 210. Under the elastic force of the elastic element 230, the inner casing 210 abuts against the instrument platform 300 and covers the instruments inside the second cavity.

[0022] Among them, such as Figure 2 As shown, after the instrument platform 300 is driven to rotate 180 degrees clockwise (or counterclockwise), the instrument can be sequentially pulled out from the inner casing 210 and the outer casing 200 for tracking (attacking) relevant targets. After tracking is completed, it enters patrol mode. To prevent damage to the instrument during patrol, the instrument platform 300 rotates 180 degrees in the opposite direction to reset, as shown. Figure 3 As shown, the instrument is brought into the inner casing 210 through the outer casing 200. The outer casing 200 is used to provide direct contact protection, such as impact (or even bulletproof), while the inner casing 210 is used for non-contact protection (such as ultrasonic attacks). By combining the two layers of protection, the instrument used to track (attack) targets is effectively prevented from being damaged during patrol, thus improving the service life of the device.

[0023] In a more specific implementation, such as Figure 3 As shown, the outer casing 200 is made of a relatively hard material such as stainless steel (or bulletproof material), which can provide the instrument with impact protection. The inner casing 210 adopts a double-layer structure. Its surface is made of rubber-based composite material and embedded with melamine foam. The former uses acoustic impedance mismatch to reflect ultrasonic waves, while the latter consumes sound wave energy through friction in its internal micropores. It also has the functions of fire resistance and high temperature resistance, providing more comprehensive protection for the instrument.

[0024] Among them, the elastic element 230 is provided with multiple springs, and the two ends of the springs are fixedly installed to the bottom of the inner box 210 and the top of the bracket 220 respectively. The springs can be rubber damping springs, which have damping characteristics. After compression, they slowly rebound by relying on the viscous friction of molecular chains, which can prevent the inner box 210 from quickly resetting and hitting the instrument platform 300, causing the instrument to vibrate violently, and thus better protect the instrument.

[0025] It is important to note that, for example Figure 2 As shown, the length and width of the instrument platform 300 are greater than the length and width of the opening of the inner box 210. The top edge of the inner box 210 has two symmetrically opened inclined surfaces 211, which makes it easier to push the inner box 210 downward when the edge of the instrument platform 300 abuts against it. A main shaft 310 runs through the inside of the instrument platform 300. The main shaft 310 is fixedly installed with the instrument platform 300. The two ends of the main shaft 310 pass out from the two opposite sides of the instrument platform 300. The ends of the main shaft 310 are connected to the device inside the robot dog body 100 that drives its rotation. Driving the main shaft 310 to rotate will drive the instrument platform 300 to rotate, thereby squeezing the inner box 210 to move downward and further compressing the spring. At this time, a channel is formed between the top of the inner box 210 and the instrument platform 300 to facilitate the entry and exit of the instrument.

[0026] The instrument platform 300 is frequently rotated, and it was found that its fit with the inner wall of the outer casing 200 is not tight, allowing sand and dirt to easily enter. This is detrimental to the later maintenance and upkeep of the equipment. Therefore, if... Figure 6 As shown, the instrument platform 300 has detachable and fixed elastic protrusions 320 on both opposite sides. The two elastic protrusions 320 are arc-shaped on the side near the outer casing 200. The elastic protrusions 320 are made of rubber, which can seal the gap between the instrument platform 300 and the outer casing 200, effectively preventing a large amount of sand and dust from entering the device during patrol. At the same time, the detachable design makes it easy to replace after wear and tear, improving the convenience of subsequent maintenance.

[0027] In practical applications, it was found that when the instrument platform 300 carries the instrument into the inner box 210, the inner box 210 needs to be pushed again (the inner box 210 is reset under the force of the spring) before the instrument can enter the second cavity opened in the inner box 210, which increases the power consumption of the robot dog.

[0028] In one specific embodiment, the inner housing 210 and the support 220 are equipped with a push-button latch (existing technology, specific structure not described). When the instrument platform 300 pushes the inner housing 210 to its lower limit (the instrument platform 300 rotates 90 degrees), the inner housing 210 and the support 220 are connected by the push-button latch. At this time, the inner housing 210 cannot move upward under the action of the spring return force. Only when the instrument platform 300 is in the reset process, pushing the inner housing 210 downward is sufficient to unlock the push-button latch.

[0029] By setting a push-button latch, repeated large-stroke pushing can be avoided, reducing the energy consumption inside the robot dog.

[0030] After the push-button lock is locked, there are two unlocking scenarios: one is that the instrument platform 300 flips and resets, pushing the inner box 210 down to unlock; the other is that the robot dog body 100 experiences violent shaking when moving to track the target, causing the inner box 210 to suddenly increase the pressure on the spring, which is greater than the force required to overcome further compression of the spring, causing the inner box 210 to move down and the push-button lock to unlock unexpectedly.

[0031] In one specific design, an anti-loosening mechanism 400 is provided between the inner housing 210 and the bracket 220. The anti-loosening mechanism 400 can be used to prevent the push-button lock from being accidentally unlocked.

[0032] More specifically, the anti-loosening mechanism 400 includes a first shaft 410 and a second shaft 420. When the instrument platform 300 is rotated 180 degrees to place the instrument in the external environment, the bottom end of the first shaft 410 abuts against the top end of the second shaft 420. At this time, the inner box 210 and the bracket 220 are integrated. No matter how the robot dog body 100 is shaken, the inner box 210 will not slide down to compress the spring. Only when the instrument platform 300 rotates in the opposite direction to reset will the second shaft 420 disengage from the first shaft 410. When the instrument platform 300 pushes the inner box 210, the two have separated by a sufficient distance, which facilitates the downward movement of the inner box 210 and unlocks the push-type lock.

[0033] More specifically, such as Figure 5 As shown, multiple first shafts 410 are provided, each of which is disposed inside a multiple spring and fixedly installed to the bottom of the inner housing 210. Multiple second shafts 420 are provided, and the surface of the bracket 220 has multiple through holes 221 adapted to the second shafts 420. The multiple second shafts 420 are slidably installed in the corresponding through holes 221 (see...). Figure 7 ).

[0034] like Figure 3As shown, the bracket 220 has a U-shaped structure with the opening facing downwards. A transmission mechanism 500 for driving the second shaft 420 to slide in the through hole 221 is provided between the bracket 220 and the bottom of the first cavity.

[0035] More specifically, the transmission mechanism 500 includes a drive sprocket 510, a chain 520, a driven sprocket 530, and a third shaft 540. The surface of the third shaft 540 is provided with external threads. The third shaft 540 is rotatably connected to the bracket 220. One end of the third shaft 540 passes through the outer surface of the outer housing 200 and is fixedly installed at the rotation center of the driven sprocket 530. The drive sprocket 510 is fixedly sleeved on the surface of the main shaft 310. After the chain 520 is tightened, it is sleeved between the drive sprocket 510 and the driven sprocket 530.

[0036] The transmission mechanism 500 also includes a slider 550, a rack 560, multiple gears 570, and multiple fourth shafts 580. One end of each of the multiple fourth shafts 580 is fixedly installed at the rotation center of the multiple gears 570. Each fourth shaft 580 is also provided with an external thread. The multiple fourth shafts 580 are inserted into the interior of the multiple second shafts 420 from the bottom end and are threadedly connected to them. The multiple gears 570 are rotatably connected to the bottom of the first cavity. The rack 560 is slidably installed at the bottom of the first cavity and meshes with the multiple gears 570 at the same time. The slider 550 is also slidably installed at the bottom of the first cavity and fixedly installed at one end of the rack 560. One end of the third shaft 540 passes through the outer surface of the slider 550 and is threadedly connected to it.

[0037] By setting up a transmission mechanism 500, when the instrument platform 300 is flipped, the main shaft 310 drives the active toothed sprocket 510 to rotate, which in turn drives the driven toothed sprocket 530 to rotate through the chain 520. The driven toothed sprocket 530 drives the third shaft 540 to rotate, which in turn drives the slider 550 to slide at the bottom of the first cavity through the thread, which in turn drives the rack 560 to slide. The rack 560 simultaneously drives multiple gears 570 to rotate in the same direction, which in turn drives the fourth shaft 580 to drive the second shaft 420 to slide in the through hole 221 through the thread.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
