Description

Technical Field

[0001] This utility model relates to the field of robotics technology, specifically to a lifting bridge gimbal module. Background Technology

[0002] In large-scale outdoor robot applications (such as photovoltaic inspection and perimeter monitoring), stable wireless network coverage and flexible video surveillance capabilities are core requirements.

[0003] Traditional solutions typically employ omnidirectional base stations for local area network deployment, but their coverage distance is limited, requiring dense base station deployment which leads to high costs, especially in scenarios with narrow roads where long-distance transmission needs cannot be met. Furthermore, while directional bridges can achieve long-distance bridging, their vertical coverage is limited by their installation height: long-distance scenarios require lower installation heights to reduce signal attenuation, while short-distance scenarios require higher heights to minimize vertical deviation, posing a dynamic adjustment requirement for fixed-installation bridges. Simultaneously, the gimbal camera mounted on the robot needs to flexibly adjust its field of view according to the height of the target being detected (such as photovoltaic panels or perimeter fencing).

[0004] In existing technologies, the pan-tilt unit is often installed independently from the network bridge, which requires the equipment to be equipped with redundant lifting mechanisms. This not only increases the structural complexity and manufacturing cost, but also causes problems such as easy wear and tangling of cables during lifting. Utility Model Content

[0005] In view of this, the present invention provides a lifting bridge gimbal module to solve the problem that in the prior art, the gimbal is often installed independently from the bridge, which leads to the need for redundant lifting mechanisms in the equipment. This not only increases the structural complexity and manufacturing cost, but also causes the cables to wear out and become tangled during the lifting motion.

[0006] This utility model provides a lifting bridge gimbal module, including:

[0007] The lifting mechanism has its bottom adapted to be fixed to the support platform of the robot body;

[0008] A wire mesh bridge mounting frame is fixed to the side of the lifting mechanism, and a directional wire mesh bridge is mounted on the wire mesh bridge mounting frame;

[0009] A gimbal assembly is fixed to the top of the lifting mechanism, and the gimbal assembly includes a pitch motor, a horizontal rotation motor, and a camera;

[0010] The cable has its top end connected to the directional bridge and the gimbal assembly for signal connection, and its bottom end is suitable for signal connection to an external control device.

[0011] The lifting mechanism's lifting action synchronously drives the movement of the network bridge mounting frame and the gimbal assembly.

[0012] When the robot moves to the target area, the lifting mechanism drives the wire bridge mounting frame fixed to its side and the gimbal assembly on top to move vertically in sync through telescopic movement. The directional wire bridge on the mounting frame dynamically adjusts its signal transmission angle according to the height of the lift to adapt to the wireless transmission requirements of different distances. At the same time, the pitch motor and horizontal rotation motor of the gimbal assembly drive the camera to rotate at multiple angles according to external control commands to capture monitoring images in real time. The cable connecting the directional wire bridge and the gimbal assembly maintains a stable signal connection with the external control device through adaptive telescopic extension during the lifting process.

[0013] By using the synchronous drive mechanism of the lifting mechanism, the height of the directional bridge and the field of view of the camera can be adjusted in an integrated manner, avoiding the equipment redundancy and cable pulling risks caused by the independent lifting of the bridge and the pan-tilt unit. At the same time, it ensures the dynamic matching of wireless signal strength and monitoring field of view, improving the communication stability and inspection efficiency of the robot in complex terrain.

[0014] In one alternative embodiment, the lifting bridge gimbal module further includes a support arm disposed between the lifting mechanism and the gimbal assembly.

[0015] The gimbal assembly is fixed to the top of the lifting mechanism via a support arm.

[0016] When the lifting mechanism performs a lifting action, the support arm fixed to its top moves vertically in sync with the telescopic movement. The support arm is rigidly connected to combine the gimbal assembly and the lifting mechanism into an integral structure, so that the lifting height of the gimbal assembly is strictly consistent with the telescopic stroke of the lifting mechanism.

[0017] In one alternative implementation, the support arm includes:

[0018] The base plate is fixed to the top of the lifting mechanism;

[0019] Four fasteners are inserted and fixed at the four corners of the base plate;

[0020] A top plate is disposed on the upper side of the bottom plate, and the top plate is fixed to the fasteners at its four corners, with a gap between the bottom plate and the top plate.

[0021] In one optional embodiment, the lifting bridge gimbal module further includes an L-shaped connector, which is disposed between the bridge mounting frame and the support arm, and the bridge mounting frame is fixed to the support arm via the L-shaped connector.

[0022] During installation, first, the vertical plate of the L-shaped connector is attached and fixed to the support bridge mounting frame with bolts. Then, the horizontal plate of the L-shaped connector is attached to the support arm, and another set of bolts is used to pass through the adjustment hole on the horizontal plate and lock it with the mounting surface of the support arm. The adjustment hole is a transverse long groove structure, which allows the horizontal plate to slide laterally relative to the support arm. After determining the position, the adjustment hole on the horizontal plate is locked with the mounting surface of the support arm.

[0023] In one optional embodiment, the vertical plate of the L-shaped connector is connected to the bridge mounting frame, the vertical plate has an elongated hole, and the bridge mounting frame is fixed to the L-shaped connector by bolts provided in the elongated hole.

[0024] During installation, after attaching the vertical plate to the side of the bridge mounting frame, pass the bolt through the elongated hole on the vertical plate and thread it into the screw hole on the side wall of the bridge mounting frame. Adjust the position of the L-shaped connector relative to the bridge mounting frame by sliding the bolt in the elongated hole. Then tighten the bolts on both sides symmetrically to lock the relative position of the vertical plate and the bridge mounting frame.

[0025] By using the combination of elongated holes and bolts, the positioning and adjustment of the cable bridge mounting frame and L-shaped connectors can be achieved, ensuring that the installation spacing between the two can adapt to different working conditions.

[0026] In one alternative embodiment, the horizontal plate of the L-shaped connector is fixed to the top plate.

[0027] In one alternative implementation, the cable is a spring wire.

[0028] When the lifting mechanism performs the lifting action, the spring wire, through the elastic expansion and contraction characteristics of its own spiral structure, adaptively compensates for the changes in cable length between the bridge mounting frame, the gimbal assembly, and the fixed end during the lifting process. This avoids the risk of bending fatigue or breakage caused by repeated stretching of traditional fixed cables. At the same time, the coiled shape of the spring wire naturally unfolds or contracts when the lifting height changes, eliminating the need for an additional cable guiding mechanism. This simplifies the design complexity of the cable storage path and maintains stable contact between the cable and the connection port through elastic tension, preventing signal interruption or power instability caused by cable loosening.

[0029] In one alternative implementation, the spring wire is arranged vertically.

[0030] In one alternative implementation, the lifting mechanism is a scissor lift or a screw lift, the bottom of which is fixed to the support platform of the robot body via a flange.

[0031] In one alternative embodiment, a gasket is provided between the bottom flange of the lifting mechanism and the robot carrying platform. Attached Figure Description

[0046] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0047] In large-scale outdoor robot applications (such as photovoltaic inspection and perimeter monitoring), stable wireless network coverage and flexible video surveillance capabilities are core requirements.

[0048] Traditional solutions typically employ omnidirectional base stations for local area network deployment, but their coverage distance is limited, requiring dense base station deployment which leads to high costs, especially in scenarios with narrow roads where long-distance transmission needs cannot be met. Furthermore, while directional bridges can achieve long-distance bridging, their vertical coverage is limited by their installation height: long-distance scenarios require lower installation heights to reduce signal attenuation, while short-distance scenarios require higher heights to minimize vertical deviation, posing a dynamic adjustment requirement for fixed-installation bridges. Simultaneously, the gimbal camera mounted on the robot needs to flexibly adjust its field of view according to the height of the target being detected (such as photovoltaic panels or perimeter fencing).

[0049] In existing technologies, the pan-tilt unit is often installed independently from the network bridge, which requires the equipment to be equipped with redundant lifting mechanisms. This not only increases the structural complexity and manufacturing cost, but also causes problems such as easy wear and tangling of cables during lifting.

[0050] The following is combined Figures 1 to 2 The following describes embodiments of the present invention.

[0051] According to an embodiment of the present invention, a lifting bridge gimbal module is provided, including a lifting mechanism 1, a bridge mounting frame 2, a gimbal assembly 4, and a cable 5.

[0052] Specifically, the bottom of the lifting mechanism 1 is suitable for fixing to the support platform of the robot body; the wire bridge mounting frame 2 is fixed to the side of the lifting mechanism 1, and a directional wire bridge 3 is installed on the wire bridge mounting frame 2; the gimbal assembly 4 is fixed to the top of the lifting mechanism 1, and the gimbal assembly 4 includes a pitch motor, a horizontal rotation motor and a camera; the top end of the cable 5 is connected to the directional wire bridge 3 and the gimbal assembly 4 for signal connection, and the bottom end of the cable 5 is suitable for signal connection to an external control device; wherein, the lifting action of the lifting mechanism 1 synchronously drives the wire bridge mounting frame 2 and the gimbal assembly 4 to move.

[0053] The working principle of the lifting bridge gimbal module is as follows:

[0054] When the robot moves to the target area, the lifting mechanism 1 drives the wire bridge mounting frame 2 fixed to its side and the gimbal assembly 4 on top to move vertically in sync through telescopic movement. The directional wire bridge 3 on the wire bridge mounting frame 2 dynamically adjusts the signal transmission angle according to the change of lifting height to adapt to the wireless transmission requirements of different distances.

[0055] Meanwhile, the pitch motor and horizontal rotation motor of the gimbal assembly 4 drive the camera to rotate at multiple angles according to external control commands, capturing monitoring images in real time. The cable 5 connecting the directional bridge 3 and the gimbal assembly 4 maintains a stable signal connection with the external control device through adaptive extension and retraction during the lifting process.

[0056] The above embodiment achieves integrated adjustment of the height of the directional bridge 3 and the field of view of the camera through the synchronous drive mechanism of the lifting mechanism 1, avoiding the equipment redundancy and cable 5 pulling risks caused by the independent lifting of the bridge and the pan-tilt unit. At the same time, it ensures the dynamic matching of wireless signal strength and monitoring field of view, and improves the communication stability and inspection efficiency of the robot in complex terrain.

[0057] In one embodiment, the lifting bridge gimbal module further includes a support arm 6, which is disposed between the lifting mechanism 1 and the gimbal assembly 4; the gimbal assembly 4 is fixed to the top of the lifting mechanism 1 by the support arm 6.

[0058] When the lifting mechanism 1 performs a lifting action, the support arm 6 fixed at its top moves vertically in sync with the telescopic movement. The support arm 6 connects the gimbal assembly 4 and the lifting mechanism 1 into an integral structure through a rigid connection, so that the lifting height of the gimbal assembly 4 is strictly consistent with the telescopic stroke of the lifting mechanism 1.

[0059] In one embodiment, the support arm 6 includes a base plate 61, four fasteners 62 and a top plate 63. The base plate 61 is fixed to the top of the lifting mechanism 1. The four fasteners 62 are inserted and fixed at the four corners of the base plate 61. The top plate 63 is located on the upper side of the base plate 61. The four corners of the top plate 63 are fixed to the fasteners 62, and there is a gap between the base plate 61 and the top plate 63.

[0060] Among them, fastener 62 is a cylindrical bolt.

[0061] In one embodiment, the lifting bridge gimbal module further includes an L-shaped connector 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 connector 7.

[0062] During installation, first, the vertical plate of the L-shaped connector 7 is attached and fixed to the support bridge mounting bracket 2 with bolts. Then, the horizontal plate of the L-shaped connector 7 is attached to the support arm 6. Another set of bolts is passed through the adjustment hole on the horizontal plate and locked to the mounting surface of the support arm 6. The adjustment hole is a transverse long groove structure, which allows the horizontal plate to slide laterally relative to the support arm 6. After determining the position, the adjustment hole on the horizontal plate is locked to the mounting surface of the support arm 6.

[0063] In one embodiment, the vertical plate of the L-shaped connector 7 is connected to the bridge mounting frame 2. An elongated hole is provided on the vertical plate, and the bridge mounting frame 2 is fixed to the L-shaped connector 7 by bolts provided in the elongated hole.

[0064] During installation, after attaching the vertical plate to the side of the bridge mounting frame 2, the bolts are passed through the elongated holes on the vertical plate and threaded into the screw holes on the side wall of the bridge mounting frame 2. The position of the L-shaped connector 7 relative to the bridge mounting frame 2 is adjusted by sliding the bolts in the elongated holes. Then, the bolts on both sides are tightened symmetrically to lock the relative position of the vertical plate and the bridge mounting frame 2.

[0065] The positioning and adjustment of the cable bridge mounting bracket 2 and the L-shaped connector 7 are achieved by using the elongated hole and bolts to ensure that the installation distance between the two is adapted to different working conditions.

[0066] In one embodiment, the horizontal plate of the L-shaped connector 7 is fixed to the top plate 63.

[0067] In one embodiment, cable 5 is a spring wire.

[0068] When the lifting mechanism 1 performs the lifting action, the spring wire, through the elastic expansion and contraction characteristics of its own spiral structure, adaptively compensates for the change in the length of the cable 5 between the bridge mounting frame 2, the gimbal assembly 4 and the fixed end during the lifting process, avoiding the risk of bending fatigue or breakage caused by repeated stretching of the traditional fixed cable 5; at the same time, the coiled shape of the spring wire naturally unfolds or contracts when the lifting height changes, without the need for an additional cable 5 guiding mechanism, which simplifies the design complexity of the cable 5 storage path, and maintains stable contact between the cable 5 and the connection port through elastic tension, preventing signal interruption or power instability caused by the cable 5 becoming loose.

[0069] In one embodiment, the spring wire is arranged vertically.

[0070] In one embodiment, the lifting mechanism 1 is a scissor lift or a screw lift, and its bottom is fixed to the support platform of the robot body by a flange.

[0071] like Figure 1 In the structure shown, the lifting mechanism 1 is a screw-type lifting frame, whose bottom is fixed to the support platform of the robot body via a flange. The screw-type lifting frame is an existing structure and can be directly adopted in this embodiment.

[0072] In one embodiment, a gasket is provided between the bottom flange of the lifting mechanism 1 and the robot carrying platform.

[0073] The overall working process of the lifting bridge gimbal module is as follows:

[0074] When the robot moves to the work area, the lifting mechanism 1 drives the telescopic rod to rise and fall according to the preset height command, and simultaneously drives the support arm 6 and the gimbal assembly 4 fixed on its top to rise or fall vertically. At the same time, the side net bridge mounting frame 2 adjusts the erection height of the directional net bridge 3 in conjunction with the lifting mechanism 1 through the L-shaped connector 7.

[0075] During this process, the pitch motor and horizontal rotation motor of the gimbal assembly 4 adjust the pitch angle and horizontal orientation of the camera according to the external control signal to capture the target image. The spring cable automatically extends and retracts with the lifting stroke to adapt to the length changes of the cable 5 of the bridge mounting bracket 2, the gimbal assembly 4 and the fixed end, ensuring the continuity of power supply and data transmission.

[0076] Through the dynamic height adjustment of the lifting mechanism 1, the antenna pointing of the directional bridge 3 is synchronously adapted to the communication and monitoring needs at different distances with the camera's field of view, ultimately achieving coordinated optimization of the robot's wireless signal coverage and visual inspection accuracy.

[0077] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
