Detailed Implementation

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention. Furthermore, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. The descriptions such as "first" and "second" used in this embodiment are only used to distinguish different institutions and do not refer to the order or a specific number. Example

[0029] like Figure 1 and Figure 2 As shown, the battery quick-swap system in this embodiment includes a battery quick-swap mechanism 1 and a battery swapping vehicle 2.

[0030] The battery quick-change mechanism 1 includes a door 11 and a battery compartment 12. The door 11 is hinged to the robot body via a rotating shaft 13. The free end of the door 11 is provided with a first mating part 14, which is connected to a second mating part 15 on the robot via a detachable connector 19. In this embodiment, the detachable connector 19 is preferably a pin, which has a simple structure and is easy to operate. Of course, buckles, magnetic devices, or electromagnetic locks can also be used to achieve a detachable connection.

[0031] The battery compartment 12 is equipped with a rolling assembly 16 for supporting and guiding the pushing and pulling of the battery 3. In this embodiment, the rolling assembly 16 is preferably a roller arranged along the direction of battery movement to reduce friction. It can be understood that the rolling assembly can also adopt equivalent structures such as rollers, sliders, or guide rails.

[0032] A battery connector 17 is located at the rear end of the battery compartment 12, and a limiter 18 is located at the front end. The battery connector 17 is electrically connected to the robot's management system. Figure 4As shown, the battery connector 17 preferably uses a flexible contact terminal with an automatic alignment function. When the battery 3 is pushed into the battery compartment 12 and positioned, its battery interface 31 is reliably connected to the battery connector 17, enabling power supply. The limiter 18 is used to detect whether the battery 3 is installed in place. When the battery is pushed in, the limiter can lock the battery to achieve a limit. In another preferred embodiment, the limiter can be a micro switch, photoelectric sensor, or proximity sensor, etc., to detect whether the battery is in place.

[0033] like Figure 3 As shown, the battery swapping vehicle 2 includes a frame 21, a battery carrying mechanism 22, a handle 23, and a wheel set 24. The battery carrying mechanism 22 is used to carry the spare battery and the old battery to be replaced. In this embodiment, the battery carrying mechanism 22 adopts a roller mechanism to facilitate battery sliding. Alternatively, a conveyor belt or sliding platform structure can also be used.

[0034] The battery carrying mechanism 22 has a docking mechanism 25 and a movable stop bar 26 on one side, and a fixed stop bar 27 on the other side. The fixed stop bar 27 is used to prevent the battery from sliding out during normal operation and movement. One end of the movable stop bar 26 is hinged to the frame 21 via a movable shaft, and the other end can be freely raised or lowered into a fixed slot on the frame. When it is necessary to remove the battery, the movable stop bar 26 can be raised; after the battery is placed, the movable stop bar 26 can be lowered to prevent the battery from slipping out during movement.

[0035] The armrest 23 is equipped with a fixing device 28 for securing the movable stop 26 when it is in the raised position, facilitating battery replacement with both hands. In this embodiment, the fixing device is preferably a magnet, and the corresponding part of the movable stop 26 is made of a magnetic material. Of course, the fixing device can also be a slot or a mechanical lock, etc.

[0036] The battery carrying mechanism 22 is provided with at least two battery receiving positions 29, and the corresponding docking mechanism 25 is provided with at least two.

[0037] The docking mechanism 25 is used to precisely dock and position itself with the opening end of the battery compartment 12 when the battery swapping vehicle approaches the robot. In this embodiment, the docking mechanism 25 can be designed as a concave arc-shaped surface, while the opening end of the battery compartment 12 is correspondingly provided with a convex arc-shaped surface, achieving guidance and positioning through the interaction of the arc surfaces. As another preferred embodiment, the docking mechanism 25 can also be a wedge-shaped guide strip, which cooperates with the guide groove correspondingly provided at the opening end of the battery compartment 12, using the inclined surface to achieve automatic correction and positioning.

[0038] The wheel set 24 includes swivel wheels and a braking device. The braking device is a foot-operated braking mechanism installed on at least one swivel wheel, which facilitates the flexible movement and reliable parking of the battery swapping vehicle 2.

[0039] Battery replacement process:

[0040] 1. Preparation: Place the fully charged battery into the empty battery compartment 29 of the battery swapping vehicle;

[0041] 2. Open the hatch: Disconnect the detachable connector (e.g., pull up the latch) and open the hatch 11 on the robot;

[0042] 3. Positioning and docking: Push the battery swapping cart 2 next to the robot so that the docking mechanism 25 on the cart is aligned and fitted with the opening end of the battery compartment 12 to achieve positioning;

[0043] 4. Remove the old battery: Lift and fix the movable stop bar 26, release the limiter 18, pull the old battery in the battery compartment 12 out along the rolling assembly 16, and place it in the empty battery holding position of the battery swapping vehicle 2;

[0044] 5. Install new battery: Move the battery swapping vehicle, accurately position the docking mechanism and the battery compartment, push the fully charged battery into the battery compartment 12 along the rolling assembly 16, and after it is in place, rotate the limiter 18 to limit the battery, and ensure that the battery connector and the battery interface 31 are reliably connected.

[0045] 6. Replacement complete: Close and lock the hatch 11, remove the battery replacement vehicle 2, and the battery replacement is complete.
