Description
Technical Field
[0001] The present invention relates to the field of robotics and automation equipment technology, and in particular to a modular battery connection device for a mobile robot with magnetic quick-disconnect and battery-changing capabilities. Background Art
[0002] With the widespread application of mobile robot technology in logistics, warehousing, inspection operations, emergency rescue, and other fields, the endurance of mobile robots has become a key factor limiting their efficiency and scope of application. To meet the needs of long-term operations, modular battery replacement technology has gradually become a mainstream solution, enabling continuous operation of mobile robots through the rapid replacement of battery packs. However, existing mobile robot battery docking technology still has many shortcomings. During the battery docking process, traditional magnetic docking structures often use a single permanent magnet design, relying solely on fixed magnetic force to achieve connection. This makes it difficult to adjust the docking force according to actual working conditions, resulting in low docking accuracy and susceptibility to interference, leading to docking failure. Furthermore, the lack of effective guidance and calibration mechanisms makes it easy for battery packs to be inserted incorrectly, which not only affects power supply stability but can also cause serious consequences such as battery short circuits and equipment damage. Regarding the stability of battery connections, conventional mechanical locking structures are complex and rely heavily on manually operated components such as bolts and clips. This makes it impossible to achieve automated and rapid locking and disconnection, seriously affecting battery replacement efficiency. Furthermore, during mobile robot operation, existing locking structures are unable to withstand external forces such as vibration and bumps, posing a risk of battery loosening or even falling off.

It does not require complex electronic control or hydraulic systems, and achieves rapid locking and release in a purely mechanical way, reducing costs and improving operational safety.
[0021] The heat dissipation mechanism 6 comprises an external frame 601. A through-hole 602 is provided on one side of the external frame 601 near the battery compartment 4.

The card slot 13 cooperates with the battery connecting plate 5 to realize mechanical positioning and electrical connection between battery components, ensuring stable installation and orderly line layout.
[0024] The elastic locking mechanism 9 is arranged near the connection part of the battery compartment 4 or the auxiliary battery holder 3. The elastic locking mechanism 9 is deployed near the connection part between the battery compartment 4 and the auxiliary battery holder 3.

The anti-misinsertion self-calibration positioning mechanism 14 is installed at the docking port of the battery compartment 4 and the auxiliary battery holder 3. In the initial stage of docking, rough positioning is achieved through the geometric cooperation of the docking slot 1402 and the self-calibration docking slot 1403.

Automatic calibration is achieved through mechatronic design. Compared with the method of post-detection and correction, it eliminates connection errors from the source and improves equipment safety and operational convenience.
[0026] In the present invention, the battery compartment 4 and the auxiliary battery holder 3 are moved to the docking position by the mobile robot 1, and the mounting slot 2 provides a stable carrying space. The bipolar magnetic guide docking mechanism 8 is activated, and the positive magnet 803 and the negative magnet 804 generate an initial magnetic force to guide the contact connection block 1 801 and the contact connection block 2 802 to initially approach each other; at the same time, the power controller 810 controls the coil 811 to generate an electromagnetic force to enhance or weaken the suction force between the permanent magnets to achieve precise docking. The micro electric telescopic rod 1 806 fine-tunes the position of the docking plate 805 according to the control instructions to ensure the docking accuracy. The epoxy resin rubber ring 1 808 and the epoxy resin rubber ring 2 809 provide sealing and buffering to prevent external environmental interference and collision damage. The mobile robot is combined with an adjustable bipolar magnetic docking mechanism to achieve automatic and precise docking of the battery assembly in a mobile state. Through the composite control of permanent magnet and electromagnetic force, it breaks through the limitations of traditional single magnetic docking and improves the flexibility and reliability of docking. During the docking process between the battery compartment 4 and the auxiliary battery holder 3, the anti-misinsertion self-calibration positioning mechanism 14 comes into play. The docking slot 1402 on the support cylinder 1401 is initially aligned with the self-calibration docking slot 1403. The second micro-electric telescopic rod 1405 drives the docking rod 1404 to extend and precisely insert into the docking slot 1402, completing the calibration and locking action. This prevents misinsertion due to angle or position deviation and ensures that the connection direction and position of the battery assembly are accurate. An automated anti-misinsertion calibration mechanism is proposed, which uses the electric telescopic rod and the slot to achieve real-time monitoring and error correction during the docking process. Compared with traditional manual calibration or simple mechanical limiters, it greatly improves connection accuracy and operational efficiency.
[0027] The elastic locking mechanism 9 is activated after the battery assembly is docked, and the compression spring 908 pushes the movable plate 903 to move along the fixed vertical rod 907, so that the groove 904 is engaged with the buckle groove 902 on the fixed plate 901 to achieve mechanical locking. The connecting spring 906 assists the movable plate 903 in resetting and stabilizing. When the battery assembly needs to be separated, the external force overcomes the elastic force of the compression spring 908, so that the movable plate 903 moves and unlocks, completing the rapid separation. The design is based on the elastic locking structure of double springs, which takes into account both locking reliability and separation convenience. It does not require complex electronic control or hydraulic systems, and achieves rapid locking and release in a purely mechanical way, reducing costs and improving operational safety.
