Description

[Technical Field]

[0001] The present invention relates to the technical field of robots, and more particularly to a lifting bridge platform module. [Background technology]

[0002] For large-scale outdoor robotic applications (e.g., solar-powered patrol inspections and fence monitoring), stable wireless network coverage and flexible video surveillance capabilities are core requirements.

[0003] Traditional solutions typically use omnidirectional base stations to implement local area networks, but their coverage distance is limited and base stations must be densely deployed, resulting in high costs and making it difficult to meet long-distance transmission requirements, especially in scenarios with narrow and long roads. Furthermore, while directional bridges can achieve long-distance bridging, their vertical coverage is limited by their set height. In long-distance scenarios, the set height must be lowered to reduce signal attenuation, while in short-distance scenarios, the height must be increased to minimize vertical deviation, requiring dynamic adjustment of the fixed bridge. Furthermore, the pan-head camera mounted on the robot must be able to flexibly adjust its field of view according to the height of the detection target (e.g., solar panels, fence equipment, etc.).

[0004] In conventional technology, the head is usually installed independently of the bridge, which requires redundant lifting mechanisms in the equipment, which not only complicates the structure and increases manufacturing costs, but also causes problems such as cable wear and tangling during lifting operations. Summary of the Invention [Problem to be solved by the invention]

[0005] In view of the above, the present invention provides a lifting bridge head module to solve the problems of the prior art, such as the need to provide a redundant lifting mechanism in the equipment because the head is usually installed independently of the bridge, which not only complicates the structure and increases manufacturing costs, but also causes cable wear and tangles during lifting operations. [Means for solving the problem]

[0006] This invention is a lifting mechanism having a bottom adapted for fastening to a support platform of a robot body; a bridge mounting frame fixed to a side of the lifting mechanism and on which a directional bridge is mounted; a head assembly fixed to the top of the lifting mechanism and including a pitch motor, a horizontal rotation motor, and a camera; a cable having a top end signal-connected to the directional bridge and the head assembly and a bottom end suitable for signal connection to an external control device; The lifting bridge head module drives the bridge mounting frame and the head assembly to move synchronously with the lifting action of the lifting mechanism.

[0007] When the robot moves to the target area, the lifting mechanism uses telescopic movements to drive the bridge mounting frame fixed to its side and the platform assembly on top to raise and lower synchronously. The directional bridge in the bridge mounting frame dynamically adjusts the signal transmission angle according to changes in lifting height, meeting wireless transmission requirements at various distances. Meanwhile, the pitch motor and horizontal rotation motor in the platform assembly rotate the camera to multiple angles according to external control commands, capturing monitoring images in real time. Meanwhile, the cables connected to the directional bridge and platform assembly maintain a stable signal connection with the external control device by adaptively extending and retracting during the lifting process.

[0008] The synchronous drive mechanism of the lifting mechanism enables the height of the directional bridge and the camera's field of view to be adjusted in an integrated manner, avoiding the risk of equipment redundancy or cable pull-in caused by the independent lifting and lowering of the bridge and camera head. At the same time, it ensures dynamic matching of wireless signal strength and monitoring field of view, improving the communication stability and patrol inspection efficiency of the robot in complex terrain.

[0009] In one optional embodiment, the lift bridge head module further includes a support arm, the support arm being disposed between the lift mechanism and the head assembly; The head assembly is secured to the top of the lift mechanism by a support arm.

[0010] When the lifting mechanism performs lifting and lowering operations, the support arm fixed to the top of the lifting mechanism moves up and down in synchronization with the telescopic operation. The support arm integrates the pan head assembly and the lifting mechanism into an integral structure through a rigid connection, so that the lifting height of the pan head assembly closely matches the telescopic stroke of the lifting mechanism.

[0011] In one optional embodiment, the support arm comprises: a bottom plate fixed to the top of the lifting mechanism; Four fasteners inserted into the four corners of the bottom plate to fix it; The top plate is provided above the bottom plate, fixed to the fasteners at four corners, and spaced apart from the bottom plate.

[0012] In one optional embodiment, the lifting bridge head module further includes an L-shaped connecting member, the L-shaped connecting member being disposed between the bridge mounting frame and the support arm, and the bridge mounting frame being fixed to the support arm via the L-shaped connecting member.

[0013] To install, first fasten the vertical plate of the L-shaped connecting member to the bridge mounting frame with a bolt. Next, fasten the horizontal plate of the L-shaped connecting member to the support arm, and then insert another bolt through the horizontal plate's adjustment hole to lock it to the support arm's mounting surface. The adjustment hole has a long horizontal slot structure, allowing the horizontal plate to slide laterally relative to the support arm. Once in position, lock the horizontal plate's adjustment hole to the support arm's mounting surface.

[0014] In one optional embodiment, the vertical plate of the L-shaped connecting member is connected to the bridge mounting frame, and an oblong hole is drilled in the vertical plate, and the bridge mounting frame is fixed to the L-shaped connecting member by a bolt provided in the oblong hole.

[0015] When installing, the vertical plate is pressed tightly against the side of the bridge mounting frame, the bolts are passed through the oblong holes in the vertical plate and screwed into the threaded holes in the side walls of the bridge mounting frame, the position of the L-shaped connecting member relative to the bridge mounting frame is adjusted by sliding the bolts inside the oblong holes, and then the bolts on both sides are tightened symmetrically to lock the relative positions of the vertical plate and the bridge mounting frame.

[0016] The cooperation of the oblong holes and bolts allows the positioning and adjustment of the bridge mounting frame and the L-shaped connecting member, so that the mounting distance between the two can be adapted to the requirements of various working conditions.

[0017] In one optional embodiment, the horizontal plate of the L-shaped connecting member is fixed to the top plate.

[0018] In one optional embodiment, the cable is spring wire.

[0019] As the lifting mechanism moves up and down, the spring wire utilizes the elastic stretching properties of its helical structure to adaptively compensate for changes in the length of the cable between the bridge mounting frame, the head assembly, and the fixed end during the lifting process, avoiding the risk of bending fatigue and breakage caused by repeated stretching of traditional fixed cables. At the same time, the spring wire's coiled shape naturally stretches and contracts in response to changes in lifting and lowering, eliminating the need for a separate cable guide mechanism. This not only reduces the complexity of the cable storage design, but also ensures that the elastic tension maintains stable contact between the cable and the connection port, preventing signal interruptions and unstable power supply due to loose cables.

[0020] In one optional embodiment, the spring wire is disposed vertically.

[0021] In one optional embodiment, the lifting mechanism is a scissor-type lifting frame or a screw-type lifting frame, the bottom of which is fixed to the support platform of the robot body by a flange.

[0022] In one optional embodiment, a gasket is provided between the bottom flange of the lifting mechanism and the robot support platform. [Brief explanation of the drawings]

[0024] In order to more clearly describe the specific embodiments of the present invention or the technical solutions in the prior art, the following will briefly introduce the drawings necessary for describing the specific embodiments or the prior art. The accompanying drawings in the following description are some embodiments of the present invention, and it is obvious to those skilled in the art that other drawings can be obtained based on these drawings without any creative work.

[0025] In order to make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without any creative work fall within the protection scope of the present invention.

[0026] For large-scale outdoor robotic applications (e.g., solar-powered patrol inspections and fence monitoring), stable wireless network coverage and flexible video surveillance capabilities are core requirements.

[0027] Traditional solutions typically use omnidirectional base stations to implement local area networks, but their coverage distance is limited and base stations must be densely deployed, resulting in high costs and making it difficult to meet long-distance transmission requirements, especially in narrow and long road scenarios. Furthermore, while directional bridges can achieve long-distance bridging, their vertical coverage is limited by their set height. In long-distance scenarios, the set height must be lowered to reduce signal attenuation, while in short-distance scenarios, the height must be increased to minimize vertical deviation, requiring dynamic adjustment of the fixed bridge. At the same time, the pan-head camera mounted on the robot must be able to flexibly adjust its field of view according to the height of the detection target (e.g., solar panels, fence equipment, etc.).

[0028] In conventional technology, the head is usually installed independently of the bridge, which requires redundant lifting mechanisms in the equipment, which not only complicates the structure and increases manufacturing costs, but also causes problems such as cable wear and tangling during lifting operations.

[0029] Hereinafter, an embodiment of the present invention will be described with reference to FIGS.

[0030] According to an embodiment of the present invention, there is provided a lifting bridge head module, which includes a lifting mechanism 1, a bridge mounting frame 2, a head assembly 4, and a cable 5.

[0031] Specifically, the bottom of the lifting mechanism 1 is suitable for fixing to the support platform of the robot body, the bridge mounting frame 2 is fixed to the side of the lifting mechanism 1 and has a directional bridge 3 attached to it, the pan head assembly 4 is fixed to the top of the lifting mechanism 1 and includes a pitch motor, a horizontal rotation motor and a camera, and the top end of the cable 5 is connected to the directional bridge 3 and the pan head assembly 4 and the bottom end is suitable for connecting to an external control device. The lifting and lowering operation of the lifting mechanism 1 drives the bridge mounting frame 2 and the pan head assembly 4 to move synchronously.

[0032] The operation method of the platform assembly of the lifting bridge is as follows.

[0033] When the robot moves to the target area, the lifting mechanism 1 extends and retracts to drive the bridge mounting frame 2 fixed to its side and the platform assembly 4 at the top, causing them to rise and fall vertically in sync. Here, the directional bridge 3 on the bridge mounting frame 2 dynamically adjusts the signal transmission angle according to changes in the lifting height, meeting the wireless transmission requirements of various distances.

[0034] At the same time, the pitch motor and horizontal rotation motor of the pan head assembly 4 rotate the camera to multiple angles according to external control commands to capture the monitoring screen in real time. Meanwhile, the cable 5 connected to the directional bridge 3 and the pan head assembly 4 maintains a stable signal connection with the external control device by adaptively expanding and contracting during the lifting process.

[0035] In the above embodiment, the synchronous drive mechanism of the lifting mechanism 1 enables the height of the directional bridge 3 and the camera field of view to be adjusted in an integrated manner, avoiding the risk of equipment redundancy or cable 5 being pulled in due to the independent lifting and lowering of the bridge and the camera head, while ensuring dynamic matching of wireless signal strength and monitoring field of view, thereby improving the communication stability and patrol inspection efficiency of the robot in complex terrain.

[0036] In one embodiment, the lifting bridge head module further includes a support arm 6, which is disposed between the lifting mechanism 1 and the head assembly 4, and the head assembly 4 is fixed to the top of the lifting mechanism 1 by the support arm 6.

[0037] When the lifting mechanism 1 performs a lifting operation, the support arm 6 fixed to the top of the lifting mechanism 1 moves up and down in synchronization with the extension and retraction operation. The support arm 6 integrates the pan head assembly 4 and the lifting mechanism 1 into an integrated structure through a rigid connection, so that the lifting height of the pan head assembly 4 closely matches the extension and retraction stroke of the lifting mechanism 1.

[0038] In one embodiment, the support arm 6 includes a bottom plate 61, four fasteners 62, and a top plate 63, the bottom plate 61 is fixed to the top of the lifting mechanism 1, the four fasteners 62 are inserted into and fixed to the four corners of the bottom plate 61, the top plate 63 is provided above the bottom plate 61 and fixed to the fasteners 62 at the four corners, and a gap is provided between the bottom plate 61 and the top plate 63.

[0039] Here, a cylindrical bolt is used as the fastener 62.

[0040] In one embodiment, the lifting bridge head module further includes an L-shaped connecting member 7, which is disposed between the bridge mounting frame 2 and the support arm 6, and the bridge mounting frame 2 is fixed to the support arm 6 via the L-shaped connecting member 7.

[0041] To install, first, the vertical plate of the L-shaped connecting member 7 is tightly secured to the bridge mounting frame 2 with a bolt, then the horizontal plate of the L-shaped connecting member 7 is tightly secured to the support arm 6, and another bolt is passed through the adjustment hole in the horizontal plate to lock it to the mounting surface of the support arm 6. The adjustment hole has a long slot structure running horizontally, allowing the horizontal plate to slide laterally relative to the support arm 6. Once the position is determined, the adjustment hole in the horizontal plate is locked to the mounting surface of the support arm 6.

[0042] In one embodiment, the vertical plate of the L-shaped connecting member 7 is connected to the bridge mounting frame 2, and an oblong hole is drilled in the vertical plate, and the bridge mounting frame 2 is fixed to the L-shaped connecting member 7 by a bolt provided in the oblong hole.

[0043] When installing, the vertical plate is pressed tightly against the side of the bridge mounting frame 2, the bolt is passed through the oblong hole in the vertical plate and screwed into the threaded hole in the side wall of the bridge mounting frame 2, the position of the L-shaped connecting member 7 relative to the bridge mounting frame 2 is adjusted by sliding the bolt inside the oblong hole, and then the bolts on both sides are tightened symmetrically to lock the relative positions of the vertical plate and the bridge mounting frame 2.

[0044] The cooperation of the oblong holes and the bolts allows the positioning and adjustment of the bridge mounting frame 2 and the L-shaped connecting member 7, so that the mounting distance between them can be adapted to the requirements of various working conditions.

[0045] In one embodiment, the horizontal plate of the L-shaped connecting member 7 is fixed to the top plate 63 .

[0046] In one embodiment, the cable 5 is a spring wire.

[0047] When the lifting mechanism 1 performs lifting and lowering operations, the spring wire utilizes the elastic stretching properties of its spiral structure to adaptively compensate for changes in the length of the cable 5 between the bridge mounting frame 2, the pan head assembly 4, and the fixed end during the lifting process, avoiding the risk of bending fatigue and breakage caused by repeated stretching of the conventional fixed cable 5. At the same time, the spring wire's winding shape naturally stretches and contracts in response to changes in lifting and lowering, eliminating the need for a separate guide mechanism for the cable 5. This not only reduces the complexity of the design of the cable 5 storage path, but also ensures that the elastic tension maintains stable contact between the cable 5 and the connection port, preventing signal interruptions and unstable power supply due to loose cable 5.

[0048] In one embodiment, the spring wire is vertically oriented.

[0049] In one embodiment, the lifting mechanism 1 is a scissor-type lifting frame or a screw-type lifting frame, the bottom of which is fixed to the support platform of the robot body by a flange.

[0050] 1, the lifting mechanism 1 is a screw-type lifting frame, the bottom of which is fixed to the support platform of the robot body by a flange. Since the screw-type lifting frame is a conventional structure, it can be used as is in this embodiment.

[0051] In one embodiment, a gasket is provided between the bottom flange of the lifting mechanism 1 and the robot support platform.

[0052] The overall operation process of the lifting bridge platform assembly is as follows:

[0053] When the robot moves into the working area, the lifting mechanism 1 drives the telescopic rod to move up and down in accordance with a preset height command, thereby vertically driving the support arm 6 and platform assembly 4 fixed to the top of the rod. At the same time, the bridge mounting frame 2 on the side works in conjunction with the lifting mechanism 1 via the L-shaped connecting member 7 to adjust the set height of the directional bridge 3.

[0054] During this process, the pitch motor and horizontal rotation motor of the pan head assembly 4 adjust the pitch angle and horizontal direction of the camera according to the external control signal to capture the image of the target, and the spring wire automatically expands and contracts with the lifting stroke to adapt to the change in the length of the bridge mounting frame 2, the pan head assembly 4, and the cable 5 at the fixed end, ensuring the continuity of power supply and data transmission.

[0055] Through the dynamic height adjustment of the lifting mechanism 1, the antenna direction of the directional bridge 3 and the camera field of view can be synchronously adapted to the communication and monitoring requirements of different distances, ultimately achieving coordinated optimization of the robot's wireless signal coverage range and vision-based patrol inspection accuracy.

[0056] Although the embodiments of the present invention have been described with reference to the drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and all such modifications and variations are included within the scope defined by the appended claims.
