Description

Technical Field

[0001] This invention belongs to the field of robot peripheral assembly technology, specifically relating to a loading mechanism and loading components for loading external devices onto a robot. Background Technology

[0002] As robots are increasingly used in industrial inspection, environmental monitoring, special operations, and secondary development, it is often necessary to mount various external functional devices such as sensors, image acquisition devices, and computing terminals on the robot body. Currently, the industry generally uses adapter structures to connect external devices to the robot body, but most existing adapter components only have simple hole-fitting functions, resulting in limited functionality.

[0003] Power cables, signal cables, and other wiring harnesses required for the operation of external devices are typically laid bare. During robot movement, obstacle crossing, and posture adjustment, these exposed harnesses are susceptible to scraping, pulling, and repeated bending, leading to problems such as aging, signal interruption, and power supply abnormalities over time. Furthermore, the lack of a neat and orderly restraint structure when multiple harnesses are arranged together results in a messy and disordered appearance, which not only leads to poor assembly aesthetics but also causes significant inconvenience for later wiring maintenance and equipment disassembly / reassembly. To address the shortcomings of the existing technology, this invention proposes a loading mechanism and loading components for loading external devices onto robots.

[0004] The methods described in this section are not necessarily methods that had been previously conceived or adopted. Unless otherwise specified, no method described in this section should be assumed to be prior art simply because it is included in this section. Similarly, unless otherwise specified, the issues mentioned in this section should not be considered to be accepted in any prior art. Summary of the Invention

[0005] This invention aims to solve the technical problems of existing robot external device adapter structures having limited functionality, lacking dedicated cable harness storage and management structures, making exposed cable harnesses prone to mechanical damage, resulting in chaotic wiring layouts and cumbersome subsequent maintenance and disassembly.

[0006] To achieve the above objectives, one technical solution adopted by the present invention is: A loading mechanism for loading external devices onto a robot, the loading mechanism having a first connecting part for connecting to the external device and a second connecting part for connecting to the robot; The loading mechanism has an internal cavity for storing the wiring harness of external devices; The cavity is equipped with a cable management structure, which is used to organize the cable bundles contained in the cavity.

[0007] Furthermore, the cable management structure has multiple cable management units, which are used to organize multiple cable bundles.

[0008] Furthermore, the cable management structure is provided with a plurality of first grooves spaced apart along the first direction. The first groove is a through groove that runs through the second direction. The first direction is perpendicular to the second direction. The portion of the cable management structure located between any two adjacent first grooves forms the cable management unit. The cable management unit is used for binding the cable bundle to the cable management unit.

[0009] Furthermore, the cable management unit is provided with a plurality of second slots spaced apart along a third direction. The second slots are through slots that pass through the first direction and are used for the binding structure of the cable bundle to pass through. The third direction is perpendicular to the second direction.

[0010] Furthermore, the loading mechanism also includes: Two first side plates are distributed with a left-right interval; Two second side plates, the two second side plates are distributed at an interval between the front and rear; A top plate is located on top of the two first side plates and the two second side plates; The top plate, together with the two first side plates and the two second side plates, forms the cavity.

[0011] Furthermore, the top plate is fixedly connected to the two first side plates on the left and right sides respectively to form a main frame that runs through the front and back. The two second side panels are detachably connected to the front and rear ends of the main frame, respectively, to close the front and rear ends of the main frame.

[0012] Furthermore, the second side plate includes an abutting portion and a blocking portion distributed vertically; The main frame has receiving grooves on both the front and rear sides for accommodating the abutting part, and the bottom of the receiving groove has a slot for the shielding part to be inserted. When the second side plate is assembled with the main frame, the shielding part is inserted into the slot, and the abutting part is embedded in the receiving groove and remains in contact. At this time, the upper end of the abutting part is not higher than the upper end of the main frame. The abutting part protrudes from the shielding part on the side opposite to the main frame, so as to form a step surface at the lower end of the abutting part for the user to lift upward.

[0013] Furthermore, the left and right ends of the cable management structure are detachably connected to the two first side plates, respectively; The first connecting portion is configured to longitudinally penetrate the first mounting hole in the top plate; The second connecting portion is configured as a second mounting hole that extends longitudinally through the second side plate, and the second mounting hole is configured as a stepped hole.

[0014] Furthermore, the loading mechanism is also equipped with a protective cover for protecting external equipment; The protective cover is detachably connected to the loading mechanism; Two protective covers are configured, and the two protective covers are symmetrically arranged on opposite sides of the external device; The loading mechanism has a wire passage groove on its outer side that communicates with the cavity, and the wire passage groove is used for the wire harness to pass through.

[0015] The present invention also provides a loading assembly for loading external devices onto a robot, comprising a loading mechanism as described in any of the preceding claims, wherein two loading mechanisms are configured, and in one of the two loading mechanisms, the second connecting portion of the loading mechanism is higher than the second connecting portion of the other loading mechanism.

[0016] Compared with the prior art, the present invention has the following advantages: This invention features a closed cavity inside the loading mechanism, which can store and hide all the wiring harnesses of external devices. This prevents the wiring harnesses from being scratched, pulled, and repeatedly bent by external obstacles during the robot's movement, obstacle crossing, and posture adjustment. It effectively reduces faults such as line aging, signal interruption, and power supply abnormalities, and improves the operational stability and service life of the wiring harnesses.

[0017] The cavity is equipped with a comb-like cable management structure with a first groove and a second groove, which can separate, limit and fix multiple functional wire harnesses independently, avoid wire harnesses crossing and tangling, make the overall wiring more orderly, and facilitate later line maintenance and equipment disassembly and assembly.

[0018] The second side panel adopts a plug-in detachable structure, which can be disassembled and assembled without the aid of tools. It can quickly open the front and rear space of the cavity and greatly reduce the difficulty of internal wire harness maintenance. The cable management structure also adopts a detachable connection method, which can flexibly replace the adapter structure according to the wire harness specifications and improve the device's adaptability.

[0019] The external double-sided protective cover can provide lateral physical protection for external equipment, while avoiding the working areas of equipment detection and heat dissipation, and will not interfere with the normal operation of external equipment.

[0020] In addition, the loading assembly consists of two loading mechanisms arranged at different heights, which can be adapted to the installation height requirements of different external devices. The high-position installation structure ensures that the detection equipment has a sufficient field of view, while the low-position installation structure lowers the overall center of gravity of the robot, effectively improving the stability of the robot during movement and broadening the applicable scenarios of the overall device.

Detailed Implementation

[0023] The invention will now be further described with reference to the accompanying drawings.

[0024] Please refer to Figure 1 In one or more embodiments of a loading mechanism for loading external devices onto a robot, an exemplary structure of the loading mechanism is shown. In the illustrated embodiment, the loading mechanism 1 includes a first connecting portion 1a for connecting to the external device and a second connecting portion 1b for connecting to the robot. The first connecting portion 1a is configured to achieve positioning and installation between the loading mechanism 1 and the external device, and the second connecting portion 1b is configured to achieve positioning and installation between the loading mechanism 1 and the robot body. With this configuration, the loading mechanism 1 can act as a transfer connector to assemble and connect the external device to the robot body.

[0025] Please refer to Figure 2 and Figure 3 The loading mechanism 1 has a cavity 1c inside, which is used to store the wiring harness of external devices. Specifically, the power cables, signal cables, and other wiring harnesses required for the operation of external devices can be stored and hidden inside the cavity 1c, thus preventing the wiring harnesses from being exposed. During the robot's movement, obstacle crossing, and posture adjustment, the wiring harnesses stored in the cavity 1c will not be scratched, pulled, or repeatedly bent by external obstacles, thereby reducing the probability of faults such as wire aging, signal interruption, and power supply abnormalities.

[0026] Please continue to refer to Figure 2and Figure 3 The cavity 1c is provided with a cable management structure 11, which is used to organize the wire bundles contained in the cavity 1c. With the cable management structure 11, multiple wire bundles can be neatly arranged inside the cavity 1c, avoiding messy tangling of the wire bundles, making the assembly effect more beautiful, and facilitating subsequent circuit maintenance and equipment disassembly and assembly.

[0027] In one or more exemplary but non-limiting embodiments, the cable management structure 11 has a plurality of cable management units 11a, which are used to organize multiple cable bundles. Specifically, external devices are typically equipped with multiple cable bundles with different functions, such as power cables, signal cables, and communication cables. By setting up multiple cable management units 11a, each cable bundle can be organized onto its corresponding cable management unit 11a, achieving separation and orderly arrangement of the cable bundles and avoiding cross-entanglement between different cable bundles.

[0028] Please continue to refer to Figure 2 and Figure 3 Furthermore, the cable management structure 11 is provided with a plurality of first grooves 11b spaced apart along a first direction. Each first groove 11b is a through groove extending along a second direction, perpendicular to the second direction. The portion of the cable management structure 11 located between any two adjacent first grooves 11b forms a cable management unit 11a, which is used to bind cable bundles. Specifically, in the illustrated embodiment, the cable management structure 11 is configured as a comb-like structure. The plurality of first grooves 11b divide the cable management structure 11 into a plurality of cable management units 11a, each cable management unit 11a being equivalent to a comb tooth. During cable management, cable bundles can be wrapped around the cable management unit 11a and the outer side of the corresponding cable bundle through a binding structure to fix the cable bundles to the cable management unit 11a, completing corresponding operations on multiple cable bundles, thereby achieving the separation, fixation, and orderly arrangement of the cable bundles.

[0029] It should be understood that the specific orientations of the first and second directions can be adaptively adjusted according to the actual spatial layout of the cavity 1c. In the illustrated embodiment, the first direction is the length direction of the cable management structure 11 (i.e., the left-right direction shown in the figure), and the second direction is the thickness direction of the cable management structure 11 (i.e., the up-down direction shown in the figure).

[0030] In one or more exemplary but non-limiting embodiments, the spacing of the first slots 11b can be adaptively set according to the diameter of the wire harness. For example, for wire harnesses with larger diameters, the spacing of the first slots 11b can be appropriately increased to increase the width of the wire management unit 11a and accommodate the larger diameter wire harnesses; for wire harnesses with smaller diameters, the spacing of the first slots 11b can be appropriately decreased to achieve denser fixing.

[0031] Please continue to refer to Figure 3 Furthermore, the cable management unit 11a has multiple second slots 11c spaced apart along a third direction. Each second slot 11c is a through slot extending along a first direction, used for the passage of a binding structure for securing the cable harness. The third direction is perpendicular to the second direction. Specifically, when securing the cable harness, cable ties, wire ties, or other binding structures are typically used to bind the cable harness to the cable management unit 11a. By creating multiple second slots 11c on the cable management unit 11a, the binding structure can pass through the second slots 11c and secure the cable harness to the cable management unit 11a. This prevents the binding structure from shifting along the third direction, thus fixing the cable harness in a stable position. It also facilitates the binding of multiple binding structures at intervals along the third direction within the same cable management unit 11a, allowing for multi-point securing of the same cable harness.

[0032] In one or more exemplary but non-limiting embodiments, the number of the second slots 11c can be adaptively set according to the wire harness binding requirements. For example, for wire harnesses with larger diameters, the number of the second slots 11c can be appropriately increased to form multi-point binding and enhance binding strength; for wire harnesses with smaller diameters, the number of the second slots 11c can be appropriately reduced to lower processing costs.

[0033] Please continue to refer to Figure 1 Furthermore, the loading mechanism 1 also includes two first side plates 121, two second side plates 13, and a top plate 122. The two first side plates 121 are spaced apart horizontally, and the two second side plates 13 are spaced apart front to back. The top plate 122 is located above the two first side plates 121 and the two second side plates 13. The top plate 122, together with the two first side plates 121 and the two second side plates 13, forms the cavity 1c. With the above configuration, the loading mechanism 1 forms a box-like structure with internal accommodating space, and the cavity 1c can provide a closed storage environment for the wiring harness of external devices.

[0034] Specifically, the two first side plates 121 respectively constitute the left and right side walls of the loading mechanism 1, the two second side plates 13 respectively constitute the front and rear side walls of the loading mechanism 1, and the top plate 122 constitutes the top wall of the loading mechanism 1. The aforementioned plates enclose and form a downwardly open cavity 1c, allowing the wire harness to enter the cavity from its lower opening and be organized and stored by the wire management structure 11.

[0035] Please continue to refer to Figure 2Furthermore, the top plate 122 is fixedly connected to the two first side plates 121 on its left and right sides respectively, forming a main frame 12 that runs through the front and rear. The two second side plates 13 are detachably connected to the front and rear ends of the main frame 12 to close the front and rear ends of the main frame 12. Specifically, the main frame 12 is integrally fixedly connected to the top plate 122 and the two first side plates 121 to form a U-shaped cross-section frame structure that runs through the front and rear. The two second side plates 13, as detachable sealing plates, are respectively installed at the front and rear ends of the main frame 12 to close the through opening, thereby forming the cavity 1c together with the main frame 12.

[0036] The purpose of the detachable connection design of the second side plate 13 is that when it is necessary to organize, inspect, or replace the wiring harness inside the cavity 1c, the operator can remove the second side plate 13 from the main frame 12, thereby directly entering the cavity 1c from the front or rear to perform the operation. After the operation is completed, the second side plate 13 can be reinstalled onto the main frame 12. This detachable connection method brings convenience and improves efficiency in wiring harness maintenance and equipment disassembly and assembly, and also facilitates the retrieval of items inside the cavity 1c.

[0037] Please continue to refer to Figure 1 Furthermore, the second side plate 13 includes an abutment portion 131 and a shielding portion 132 distributed vertically. The main frame 12 has receiving grooves 12a on both the front and rear sides for accommodating the abutment portion 131, and the bottom of the receiving groove 12a has a slot 12b for the shielding portion 132 to be inserted into.

[0038] When the second side plate 13 is assembled with the main frame 12, the blocking part 132 is inserted into the slot 12b, and the abutting part 131 is embedded in the receiving groove 12a and remains in contact. At this time, the upper end of the abutting part 131 is not higher than the upper end of the main frame 12, so as to maintain a simple and beautiful overall shape. Specifically, the insertion of the blocking part 132 into the slot 12b will realize the positioning of the second side plate 13 in the left-right and front-back directions, and the cooperation of the abutting part 131 into the receiving groove 12a will realize the positioning of the second side plate 13 in the vertical direction. This design is simple to disassemble and assemble; it can be disassembled by lifting it upwards, and it will be closed again by inserting it.

[0039] Furthermore, the abutment portion 131 protrudes from the blocking portion 132 on the side opposite to the main frame 12, forming a stepped surface 131a at the lower end of the abutment portion 131 for the user to lift upwards. Specifically, when it is necessary to disassemble the second side panel 13, the operator can place their fingers on the stepped surface 131a and apply upward force to remove the second side panel 13 from the main frame 12, which is simple and quick.

[0040] Please continue to refer to Figure 2 Furthermore, the left and right ends of the cable management structure 11 are detachably connected to the two first side plates 121, respectively. Specifically, the cable management structure 11 can be detachably installed between the two first side plates 121 by means of bolt connection, snap-fit ​​connection, or plug-in connection. In this embodiment, the method is bolt connection. When it is necessary to adjust the cable management method or replace the cable management structure 11 with a different specification, the operator can remove the cable management structure 11 from the first side plate 121 for replacement or adjustment, so that the loading mechanism 1 can be used flexibly.

[0041] Please continue to refer to Figure 1 The first connecting portion 1a is configured as a first mounting hole 1a1 that extends longitudinally through the top plate 122. Specifically, the first mounting hole 1a1 is a through hole extending vertically through the top plate 122, and the position of the first mounting hole 1a1 corresponds to the mounting hole position on the external device. During assembly, the fastener passes through the mounting hole of the external device and the first mounting hole 1a1 and is threaded, thereby fixing the external device onto the loading mechanism 1. The threaded fastening here can be achieved by making the first mounting hole 1a1 an internally threaded hole and directly threading it to the threaded hole, or by passing through the first mounting hole 1a1 and then threading it to the nut.

[0042] Please continue to refer to Figure 1 The second connecting portion 1b is configured as a second mounting hole 1b1 that extends longitudinally through the second side plate 13, and the second mounting hole 1b1 is configured as a stepped hole. Specifically, the second mounting hole 1b1 is a through hole extending vertically through the second side plate 13, and its position corresponds to the mounting hole position on the robot body. During assembly, fasteners pass through the second mounting hole 1b1 and screw into the mounting hole on the robot body, thereby fixing the loading mechanism 1 to the robot body.

[0043] Please continue to refer to Figure 1Furthermore, the loading mechanism 1 is also equipped with a protective cover 2 for protecting the external equipment. The protective cover 2 is detachably connected to the loading mechanism 1, for example, by means of bolt locking or snap-fit ​​connection. In this embodiment, it is configured to be bolt locking. The protective cover 2 covers the outside of the external equipment, providing physical protection against impacts, dust, and debris, thereby reducing the risk of damage to the external equipment due to bumps during robot operation and extending the service life of the equipment.

[0044] In this embodiment, two protective covers 2 are configured, symmetrically arranged on opposite sides of the external device. Specifically, the two protective covers 2 protect the external device from both sides, forming a semi-enclosed protective structure. This semi-enclosed structure provides lateral protection to the external device while avoiding the device's working areas (such as sensing areas, image acquisition areas, heat dissipation areas, etc.), thus not affecting the device's normal detection, imaging, and heat dissipation functions.

[0045] Please continue to refer to Figure 2 The loading mechanism 1 has a wire passage groove 1d on its outer side that communicates with the cavity 1c. The wire passage groove 1d is used for wire harnesses to pass through. Specifically, the wire harness of the external device needs to enter the cavity 1c before connecting to the robot. In this embodiment, the wire passage groove 1d is configured as a through groove on the top plate 122, allowing the wire harness to enter the cavity 1c through the wire passage groove 1d, thus achieving internal and external connection of the wire harness.

[0046] Please refer to Figure 4 The present invention also provides a loading assembly for loading external devices onto a robot, comprising a loading mechanism 1 as described in any of the preceding claims. Two loading mechanisms 1 are configured, arranged side-by-side, with the second connecting portion 1b of one loading mechanism 1 being higher than the second connecting portion 1b of the other loading mechanism 1.

[0047] Specifically, in the illustrated embodiment, both loading mechanisms 1 are mounted on the back of the robot, each used to carry different external devices. The robot in this embodiment is a quadruped robot. The second connecting portion 1b (i.e., the robot body connecting surface) of the rear loading mechanism 1 is positioned higher, while the second connecting portion 1b of the front loading mechanism 1 is positioned lower. This staggered configuration allows external devices (such as gimbal-type devices) mounted on the higher loading mechanism 1 to achieve a higher mounting height, thus gaining a wider field of view or detection range; while external devices mounted on the lower loading mechanism 1 do not require excessively high mounting height, which helps to lower the overall center of gravity and improve the stability of the robot during movement. By setting the second connecting portions 1b of the two loading mechanisms 1 at different heights, the differentiated mounting height requirements of different external devices can be met, improving the versatility and adaptability of the loading components.

[0048] In summary, this invention addresses the problems of existing robot external device adapter structures, such as limited functionality, exposed and easily damaged wiring harnesses, and messy wiring that hinders maintenance. It designs a loading mechanism and loading assembly. The loading mechanism connects the robot and external device via two sets of connecting parts, enabling modular and rapid assembly. The internal cavity can conceal all wiring harnesses, preventing them from being scratched, pulled, or bent during robot movement, thus reducing the incidence of wiring failures. The comb-like, detachable cable management structure within the cavity can secure various wiring harnesses in sections, preventing tangling. Combined with a detachable second side plate, the cavity can be quickly opened by hand, significantly improving the efficiency of wiring harness maintenance and device assembly / disassembly. Simultaneously, the external protective cover provides protection for the external device without affecting its performance. The loading assembly, composed of two sets of staggered loading mechanisms, can adapt to the installation height requirements of different external devices, balancing the detection field of view with the robot's operational stability. This invention features a simple structure, convenient assembly and disassembly, effectively overcoming the shortcomings of existing adapter structures, and offering greater practicality and adaptability.
