As a crucial energy supply component for robots, the stability of the connection between the battery and the robot directly affects the robot's working performance and reliability, especially for quadruped robots with large ranges of motion.

[0003] Existing robot battery connection devices, such as a utility model patent entitled "Battery Quick-Release Structure, Battery Module and Robot" (publication number: CN218769846U), have a battery structure rigidly connected inside the robot's battery compartment and connected to the robot's power input connector via a power output connector. As the robot moves, the battery structure often wobbles relative to the battery compartment, causing the power output connector on the battery structure to vibrate slightly. This results in stress between the rigidly connected power output connector and the power input connector, leading to a short lifespan for the connector and potentially affecting battery safety with long-term use.

[0013] Preferably, a first guide component is provided between the battery structure and the power socket to guide the power output connector and the power input connector to interlock; and / or,

[0014] A second guide assembly is provided between the battery structure and the mounting base to guide the battery structure into the battery compartment.

[0035] like Figures 1-8 As shown in the figure, as an embodiment of the present invention, a floating battery connection device is provided, including a battery structure 1, a mounting base 4, and a power socket 2. A power output connector 15 is provided on the outer side of the battery structure 1. A battery compartment 40 for accommodating the battery structure 1 is formed inside the mounting base 4, and the battery structure 1 and the battery compartment 40 are arranged with a gap to allow it to sway within the battery compartment 40. The power socket 2 includes a connector base and a power input connector 21 disposed on the connector base and capable of interlocking with the power output connector 15. The connector base is connected to the side wall of the battery compartment 40 via a floating mechanism. After the battery structure 1 is connected to the mounting base 4, the power output connector 15 and the power input connector 21 interlock to conduct electricity, and the power socket 2 can float relative to the mounting base 4 with the battery structure 1 via the floating mechanism. The floating battery connection device of this embodiment has a power socket 2, and the socket base is connected to the side wall of the battery compartment 40 through a floating mechanism. This allows the socket base to float relative to the mounting base 4 along with the battery structure 1. After the battery structure 1 is connected to the mounting base 4, the power socket 2 can move with the movement of the battery structure 1 relative to the mounting base 4. The power input connector 21 on the power socket 2 and the power output connector 15 on the battery structure 1 can also move with the movement of the battery structure 1. This can buffer the stress generated between the power input connector 21 and the power output connector 15 during the robot's movement, extend the service life of the power input connector 21 and the power output connector 15, improve the safety of the battery structure 1, and ensure the stability of the conductivity between the power input connector 21 and the power output connector 15. This avoids poor contact problems caused by the robot's movement and improves the reliability of the battery structure 1.

[0036] like Figure 2 As shown, in some specific embodiments, the floating mechanism includes a plurality of movable connectors 22 connected to the side wall of the battery compartment 40 and arranged around the power input connector 21, and a plurality of movable channels 26 arranged through the connector base corresponding to the movable connectors 22. The movable connectors 22 and the movable channels 26 are configured with a clearance fit to allow the connector base to float relative to the side wall of the battery compartment 40.

[0037] In some specific embodiments, the movable connector 22 includes a movable shaft 221 arranged with gaps in the movable channel 26, a connecting shaft 222 connected to one end of the movable shaft 221 and connected to the side wall of the battery compartment, and a limiting head 223 connected to the other end of the movable shaft 221 and limited to the side of the plug-in base away from the side wall of the battery compartment, so that the plug-in base can move relative to the side wall of the battery compartment, so that after the battery structure 1 is connected to the mounting base 4, the power socket 2 can sway relative to the movable shaft 221 as the battery structure 1 sways relative to the mounting base 4.

[0038] like Figure 2 As shown, in some specific embodiments, the battery structure 1 includes a battery body 10 and an operating body 11 arranged at one end of the battery body 10 along its length and connected to the battery body 10. A power output connector 15 is disposed on the battery body 10 at one end away from the operating body 11. The mounting base 4 includes a first side plate 43 corresponding to the power output connector 15 disposed on one side of the battery compartment 40. The connector base is connected to the first side plate 43 through a floating mechanism. An opening is provided at one end of the mounting base 4 along its length for the battery structure 1 to extend into the battery compartment 40. 42. The first side plate 43 is located on the side of the battery compartment 40 away from the opening 42. It allows the battery structure 1 to extend into the battery compartment 40 through the opening 42, so that the power output connector 15 can directly plug into and assemble with the power input connector 21 as the battery structure 1 extends in. It also allows the battery structure 1 to extend out of the battery compartment 40 through the opening 42, so that the power output connector 15 can directly separate from the power input connector 21 as the battery structure 1 extends out, thereby realizing quick assembly or disassembly of the battery structure 1 and facilitating the replacement of the battery structure 1. The end of the battery body 10 away from the operating body 11 is also provided with a charging port 16 for charging the battery structure 1.

[0039] like Figure 5 As shown, in some specific embodiments, the movable shaft 221 is arranged along the length of the mounting base 4, and a first radial gap 24 is formed between the movable shaft 221 and the side wall of the movable channel 26 to allow the power socket 2 to oscillate radially relative to the movable shaft 221, so that the power socket 2 as a whole can oscillate radially with the battery structure 1 to buffer the normal stress between the power output connector 15 and the power input connector 21. A first axial gap 23 is formed between the power socket 2 and the limiting head 223, or between the power socket 2 and the first side plate 43, to allow the power socket 2 to oscillate axially relative to the movable shaft 221, so that the power socket 2 as a whole can oscillate axially with the battery structure 1 to buffer the shear stress between the power output connector 15 and the power input connector 21.

[0040] like Figure 2As shown, in some specific embodiments, a first mounting channel 431 is provided through the side wall of the battery compartment 40, that is, a first mounting channel 431 is provided through the first side plate 43. The connector base includes a base body 20 that is spaced apart in the first mounting channel 431 so that it can swing within the first mounting channel 431, and a connecting plate 25 that is arranged on the outside of the side wall of the battery compartment 40, that is, on the outside of the first side plate 43 and connected to the base body 20. The power input connector 21 is disposed on the base body 20, and the movable channel 26 is disposed on the connecting plate 25. The first mounting channel 431 facilitates the assembly and positioning of the power connector 2. Moreover, the movable connector 22 and the connecting plate 25 are disposed on the outside of the first side plate 43. Compared with being disposed on the inside of the first side plate 43, they can reduce the space occupied in the battery compartment 40, thereby improving the tightness of the fit between the battery structure 1 and the battery compartment 40 and reducing the shaking amplitude of the battery structure 1. Of course, in other embodiments, the first mounting channel 431 may not be provided, and the movable connector and the connecting plate may be directly arranged inside the first side plate 43, and the power socket 2 may be swayably connected to the first side plate 43.

[0041] In some specific embodiments, the side wall of the battery compartment 40, i.e., the first side plate 43, is provided with a plurality of connecting channels 432 arranged around the first mounting channel 431. The connecting shaft 222 can pass through the movable channel 26 and be detachably connected to the connecting channel 432, which facilitates quick assembly or disassembly of the power socket 2 from outside the first side plate 43, and the power socket 2 can be disassembled relative to the first side plate 43 for easy maintenance later. After connection, the first axial gap 23 is formed between the connecting plate 25 and the limiting head 223, or between the connecting plate 25 and the side wall of the battery compartment 40, i.e., the first side plate 43, and the first radial gap is formed between the movable shaft 221 and the side wall of the movable channel 26. Optionally, the connecting shaft 222 is set as a screw structure, and the connecting channel 432 and the connecting shaft 222 are threadedly connected, which is a stable connection. The movable shaft 221 is set as a smooth round shaft to facilitate the power socket 2. The outer diameter of the connecting shaft 222 is smaller than the outer diameter of the movable shaft 221, which facilitates the assembly or disassembly of the connecting shaft 222 through the movable channel 26.

[0042] like Figure 7 , Figure 8As shown, in some specific embodiments, a shock-absorbing component is also included. Two sets of this shock-absorbing component are respectively arranged on both sides of the power socket 2 and connected to the side wall of the battery compartment 40. This buffers the movement of the battery structure 1 relative to the inner wall of the battery compartment 40, thereby buffering the rigid collision between the battery structure 1 and the mounting base 4, and also buffering the movement of the battery structure 1 relative to the inner wall of the battery compartment 40. This allows the battery structure 1 to float gently within the battery compartment 40 during robot movement. The shock-absorbing component and the floating mechanism work together to more effectively buffer the vibration and impact forces during robot movement, ensuring that the power input connector 21 and the power output connector 15 always maintain good contact, guaranteeing stable power transmission, and further improving the safety and reliability of the battery structure 1. In other embodiments, more sets of this shock-absorbing component may be provided.

[0043] In some specific embodiments, second mounting channels 433 are respectively provided through the side wall of the battery compartment 40, that is, the first side plate 43, and arranged on both sides of the power socket 2 along the width direction of the mounting base 4. The shock absorption assembly includes a contact 32 that is retractably arranged in the second mounting channel 433, a fixing seat 31 that is sleeved on the outside of the contact 32 and installed on the outside of the side wall of the battery compartment 40, that is, the outside of the first side plate 43, and a second elastic member 33 arranged between the contact 32 and the fixing seat 31. A protruding edge 321 is provided radially on the end of the contact 32 away from the battery compartment 40. The protruding edge 321 is retractably arranged in the fixing seat 31 and limited between the outside of the first side plate 43 and the fixing seat 31 to prevent the contact 32 from falling off the fixing seat 31. The contact member 32 has a released state that protrudes into the inner side of the first side plate 43 under the pressure of the second elastic member 33, and a retracted state that retracts into the fixed base 31 under the pressure of the end of the battery body 10 away from the operating body 11. After the battery structure 1 is connected to the mounting base 4, the contact member 32 is in the retracted state and abuts against the end of the battery body 10 away from the operating body 11. A second axial gap is formed between the end of the battery body 10 away from the operating body and the first side plate 43, allowing the battery body 10 to swing axially relative to the first side plate 43. This ensures that the battery structure 1 can swing axially to buffer the shear stress between the power output connector 15 and the power input connector 21. The battery body 10 can axially sway relative to the first side plate 43 as the battery structure 1 sways relative to the mounting base 4, and simultaneously squeeze the second elastic member 33 on one or both sides. After the battery body 10 sways, the elastic force of the second elastic member 33 pushes the battery structure 1 to reset, providing elastic buffer force for the axial sway of the battery structure 1 and avoiding rigid collision between the operating body 11 and the first side plate 43.

[0044] In some specific embodiments, a first guide component is provided between the battery structure 1 and the power socket 2 to guide the power output connector 15 and the power input connector 21 to plug into each other. A second guide component is provided between the battery structure 1 and the mounting base 4 to guide the battery structure 1 into the battery compartment 40. In other embodiments, only the first guide component or only the second guide component may be provided.

[0045] like Figure 4 , Figure 5 As shown, in some specific embodiments, the first guide component includes a first guide connector 151 disposed on the outside of the battery structure 1 and a second guide connector 211 disposed on the connector base that can be plugged into the first guide connector 151. The distance between the plug end of the second guide connector 211 and the side of the connector base near the battery compartment 40 is greater than the distance between the plug end of the power input connector 21 and the side of the connector base near the battery compartment 40. This allows the first guide connector 151 to first insert into the second guide connector 211 and then the power output connector 15 to insert into the power input connector 21. This allows the first guide connector 151 to move along the second guide connector 211 to guide the power output connector 15 and the power input connector 21 to plug into each other, which is beneficial for the rapid and accurate docking of the power output connector 15 and the power input connector 21.

[0046] In some specific embodiments, the power output connector 15 and the first guide connector 151 are respectively configured as recessed structures, and the power input connector 21 and the second guide connector 211 are respectively configured as protruding structures. The second guide connector 211 includes a guide portion 2111 arranged parallel to the power connector 15 and a guide portion 2112 connected to the end of the guide portion 2111 away from the connector base. Two sets of the first guide connector 151 and the second guide connector 211 are correspondingly provided. One set of the second guide connector 211 is located on the upper side of the power input connector 21, and the vertical distance between the upper surface of the guide portion 2112 of the second guide connector 211 and the power input connector 21 gradually decreases from the end closer to the connector base to the end farther from the connector base. The other set of the second guide connector 211 is located on the lower side of the power input connector 21, and the vertical distance between the lower surface of the guide portion 2112 of the second guide connector 211 and the power input connector 21 gradually decreases from the end closer to the connector base to the end farther from the connector base. When the battery structure 1 is inserted into the battery compartment 40, the two first guide connectors 151 simultaneously extend into the corresponding second guide connectors 211 under the guidance of the two guide parts 2112, achieving precise docking between the first guide connectors 151 and the second guide connectors 211. When the power socket 2 is not connected to the battery structure 1, it is tilted downwards towards the battery compartment 40 under its own weight, deflected relative to the movable channel 26. Since the two guide parts 2112 are set as inclined surfaces, the first guide connectors 151 can gradually cooperate with the second guide connectors 211 as the battery structure 1 extends into the battery compartment 40, raising the second guide connectors 211 and the power socket 2 as a whole upwards and leveling them. This allows the power output connector 15 to extend horizontally into the power input connector 21 and be plugged in, thereby reducing the stress generated between the power output connector 15 and the power input connector 21 during the installation of the battery structure 1, and further extending the service life of the power output connector 15 and the power input connector 21. Optionally, the side of the two guide portions 2112 away from the power input connector 21 is set as a conical surface, which is adapted to various tilting states of the power socket 2 when it is not connected to the battery structure 1, where it is deflected relative to the movable channel 26 and tilted directly downward, to the lower left, or to the lower right under its own weight, so that the battery structure 1 can accurately mate with the power socket 2 in various tilting states. In other embodiments, the power output connector 15 and the first guide connector 151 can also be set as protruding structures, and the power input connector 21 and the second guide connector 211 can be set as recessed structures.

[0047] like Figure 2As shown, in some specific embodiments, the mounting base 4 further includes a second side plate 44 disposed between the first side plate 43 and the opening 42, the second side plate 44 being disposed on the bottom side of the battery compartment 40, and the second guide assembly being disposed between the second side plate 44 and the battery body 10. The second guide assembly includes a guide groove 14 arranged along the length of the mounting base 4 and a guide block 41 slidably connected to the guide groove 14 and arranged with a gap. In this embodiment, the guide block 41 is disposed inside the second side plate 44, and the guide groove 14 is disposed at the bottom of the battery body 10. When the battery structure 1 extends into the battery compartment 40, the guide block 41 can move along the guide groove 14 to guide the first guide connector 141 and the second guide connector 211 to engage with each other. Thus, the guide block 41 moves along the path of the guide groove 14 and the first guide connector 151 moves along the path of the second guide connector 211 to engage with each other, which is more conducive to the accurate docking of the power output connector 15 and the power input connector 21. At the same time, since the guide block 41 and the guide groove 14 are arranged with a gap, the battery structure 1 can shake relative to the mounting base 4 to buffer the stress between the power output connector 15 and the power input connector 21. Of course, in other embodiments, the guide groove 14 may be disposed inside the second side plate 44, and the guide block 41 may be disposed at the bottom of the battery body 10.

[0048] like Figure 3 As shown, in some specific embodiments, the end of the guide groove 14 near the opening 42 is configured as a flared opening, and the width of the flared opening gradually increases from the end away from the opening 42 to the end near the opening 42, which facilitates guiding the guide block 41 into the guide groove 14 and is beneficial for the rapid installation of the battery structure 1. Furthermore, during installation, the positioning error between the guide block 41 and the guide groove 14 is less than or equal to the positioning error between the first guide connector 151 and the second guide connector 211, ensuring that after the guide block 41 and the guide groove 14 are installed and fitted, the first guide connector 151 can still be installed and fitted with the second guide connector 211.

[0049] like Figure 2 , Figure 6As shown, in some specific embodiments, the mounting base 4 further includes a third side plate 45 arranged between the first side plate 43 and the opening 42. Two third side plates 45 are arranged opposite each other, respectively on the left and right sides of the battery compartment 40. The opposing sides of the battery structure 1 are connected to the mounting base 4 by locking components, that is, the left and right sides of the battery structure 1 are connected to the two third side plates 45 by locking components. The locking components include a locking groove 451 recessed on the mounting base 4, that is, on the third side plate 45; a telescopic channel 111 corresponding to the locking groove 451 recessed on the side of the battery structure 1, that is, on the side of the operating body 11, arranged opposite to the locking groove 451; a telescopic locking tongue block 13 arranged in the telescopic channel 111; and a first elastic member 17 arranged between the locking tongue block 13 and the inner end of the telescopic channel 111. A second radial gap is formed between the side wall of the operating body 11 and the third side plate 45, allowing the operating body 11 to swing radially relative to the third side plate 45, ensuring that the battery structure 1 can swing radially to buffer the normal stress between the power output connector 15 and the power input connector 21. The locking tongue block 13 has a released state, which protrudes outward from the outside of the battery structure 1, i.e., the outside of the operating body 11, under the pressure of the first elastic member 17, and a retracted state, which retracts into the telescopic channel 111 under the pressure of the third side plate 45. After the battery structure 1 is connected to the mounting base 4, the locking tongue block 13 is in the released state and engages with the locking groove 451 to prevent the battery structure 1 from detaching from the battery compartment 40. At the same time, the first elastic member 17 is compressed between the locking tongue block 13 and the inner end of the telescopic channel 111. The operating body 11 can move radially relative to the third side plate 45 as the battery structure 1 moves radially relative to the mounting base 4, and simultaneously squeeze one or both of the first elastic members 17. After the operating body 11 moves, the elastic force of the first elastic member 17 pushes the battery structure 1 back to its original position, providing elastic buffering force for the radial movement of the battery structure 1, and avoiding rigid collision between the operating body 11 and the third side plates 45 on both sides, so as to buffer the movement of the battery structure 1 relative to the inner wall of the battery compartment 40.

[0050] like Figure 2As shown, in some specific embodiments, the operating body 11 is also provided with a handle 12 for the operator to grip. The side of the locking tongue block 13 away from the battery compartment 40 and the side of the locking tongue block near the battery compartment 40 are respectively set as slopes. The operator can grip the handle 12 to insert the battery structure 1 into the battery compartment 40 until the power output connector 15 and the power input connector 21 are plugged in and engaged. At the same time, the locking tongue block 13 slides into the locking groove 451 along the slope of the side of the locking tongue block near the battery compartment 40 and engages with the locking groove 451 to realize the installation of the battery structure 1. The operator can grip the handle 12 and pull the battery structure 1 out of the battery compartment 40 to make the locking tongue block 13 slide out of the locking groove 451 along the slope of the side of the locking tongue block away from the battery compartment 40 and disengage from the locking groove 451 to realize the disassembly of the battery structure 1. The operation is simple and convenient, and can realize the quick installation or disassembly of the battery structure 1, making it convenient to quickly replace the battery structure 1.

[0051] In some specific embodiments, the first axial gap 23, the first radial gap 24, the second axial gap, and the second radial gap are small movable gaps, allowing the battery structure 1 to slightly wiggle the power output connector 15 and the power socket 2 relative to the mounting base 4 during robot movement, thereby buffering the stress between the power output connector 15 and the power input connector 21. The first elastic element 17 and the second elastic element 33 are respectively set as compression springs, which are simple and practical in structure. In other embodiments, the first elastic element 17 or the second elastic element 33 can also be set as other elastic structures such as elastic silicone.
