Description

Technical Field

[0001] This invention belongs to the field of unmanned equipment, quick load removal and rapid replacement, and specifically relates to a structure for rapid load replacement of unmanned equipment. Background Technology

[0002] With the rapid development of the intelligent unmanned industry, the application fields of unmanned equipment are becoming increasingly widespread. The payload is a crucial component for unmanned equipment to perform tasks, and different mission scenarios require different payloads. This necessitates rapid payload replacement tailored to the specific mission scenario. Therefore, designing a simple, easy-to-operate, stable, and reliable rapid payload replacement structure has become a mainstream requirement. Currently, there are many types of rapid payload replacement structures. Most technical solutions use screws, knobs, pull pins, and slide rails, but these often require tools or manual operation for disassembly and replacement, making them inconvenient and slow. Furthermore, screws and knobs are prone to loosening in vibrating environments, and pull pins and slide rails are susceptible to wobbling, affecting payload stability. Additionally, these solutions generally lack connector design or have connectors protruding from the outside of the structure, making them vulnerable to impacts during payload placement and use, potentially damaging the equipment and affecting aesthetics. Based on the mainstream requirements and existing shortcomings, designing a rapid payload replacement structure that addresses the deficiencies of existing technologies while meeting current mainstream needs is a pressing issue.

[0003] The existing technical solutions have the following technical problems:

[0004] Existing technical solutions generally use screws, knobs, pull pins, and slide rails to achieve this, but these often require tools or manual operation to disassemble and replace, making them inconvenient and slow to operate. Moreover, screws and knobs are prone to loosening in vibrating environments, and pull pins and slide rails are prone to shaking, affecting the stability of the load.

[0005] Existing technical solutions generally do not incorporate connector design or the connectors protrude from the outside of the structure. During load placement and use, the connectors are easily bumped and damaged, which can lead to equipment damage. Moreover, they are not aesthetically pleasing. Summary of the Invention

[0041] Working principle:

[0042] When the intelligent equipment with the fixed component (22) already installed needs to be loaded, the load containing the movable component (23) is taken out with one hand. The upper working surface of the front end of the sliding frame (8) in the movable component (23) is aligned with the insertion guide surface (103) of the left limit guide rail (1) and the right limit guide rail (6), and the lower working surface of the front end of the sliding frame (8) is aligned with the lower limit working surface (106) of the left limit guide rail (1) and the right limit guide rail (6). At this time, the trigger push rod (12) is pushed to the limit position to compress the spring (16). Under the action of the connecting rod and the guide mechanism, the left locking slider (13) and the right locking slider (17) are driven to retract inward, and the two are exactly inside the sliding frame (8). The upper limit working surface (101) of the left limit guide rail (1) pushes the sliding frame (8) in the movable part assembly (23) to the limit position; at this time, the first male connector (2) and the second male connector (5) are fully connected to the first female connector (9) and the second female connector (10) respectively; then the trigger push rod (12) is released, and under the action of the spring force of the spring (16), the connecting rod and the guide mechanism, the left locking slider (13) and the right locking slider (17) pop out. At this time, the conical surface at the front end of the left locking slider (13) and the right locking slider (17) is perfectly matched with the conical hole surface of the left limit guide rail (1) and the right limit guide rail (6) to ensure that the movable part of the load quick change structure is fully limited and fastened.

[0043] When it is necessary to disassemble and replace the current load, push the trigger push rod (12) in the movable part component (23) to the limit position to compress the spring (16). Under the action of the connecting rod and the guide mechanism, the left locking slider (13) and the right locking slider (17) are driven to retract inward and are completely retracted into the sliding frame (8). The conical surfaces at the front ends of the left locking slider (13) and the right locking slider (17) are pulled out from the positioning cone holes of the left limit guide rail (1) and the right limit guide rail (6). Then, pull out the movable part component (23) with force and at a uniform speed.

[0044] The core of this invention is its quick-change locking structure design that allows for one-handed operation and its concealed connector design, as detailed below:

[0045] 1) The key to the quick-change locking structure design that can be operated with one hand lies in the design of a locking structure that combines a connecting rod and a limit guide rail.
