Detailed Implementation

[0037] The technical solutions of this application will be further described below with reference to specific embodiments, but this application is not limited to these embodiments.

[0038] like Figures 1 to 12 As shown, this embodiment proposes a battery structure, including:

[0039] The housing assembly 11 has a housing component 12, a first end cap 13 and a second end cap 14. The housing component 12 has an inner cavity for installing an energy storage module, and one end of the housing component 12 is provided with the first end cap 13 and the other end of the housing component 12 is provided with the second end cap 14. The first end cap 13 has an end face 15 and a side face 16, and the side face 16 is used to connect to the housing component 12.

[0040] The guide rail limiting structure 17 is disposed on the housing component 12;

[0041] The locking device 18 is mounted on the first end cover 13 via an elastic member 22. The locking device 18 has a locking tongue 19 and an adjustment part 20. The end face 15 is provided with a first adjustment port 21 for installing the adjustment part 20, and the side face 16 is provided with a clearance port 23 for installing the locking tongue 19. The elastic member 22 is used to push the locking tongue 19 out of the clearance port 23.

[0042] In this design, the locking device 18 is integrated into the first end cap 13. The elastic element 22 provides a continuous pushing force to the locking tongue 19, causing it to automatically pop out of the clearance opening 23, forming a mechanical lock with the external structure. This design eliminates the need for manual operation, simplifying the assembly process and effectively improving battery installation efficiency. The guide rail limiting structure 17 ensures precise guidance of the battery structure during installation, preventing jamming and misalignment.

[0043] The energy storage module includes battery cell components, and the housing component 12 also houses the BMS component 40 and the PACK component 41. The front end of the housing component 11 is the assembly end, and the rear end is the connection end. The overall structure is compact and easy to install in a robot.

[0044] The first end cap 13 at the front end of the housing assembly 11 is also equipped with a switch 37 and a power indicator light 38. The switch 37 controls the on / off state of the battery power. A silicone sealing gasket is installed inside the button of the switch 37. Depending on the specific installation environment, and without affecting the battery structure and installation, sealing can be applied to areas requiring waterproofing. The power indicator light 38 displays the current battery power status, allowing the operator to monitor battery usage in real time.

[0045] As one embodiment of this example, the locking device 18 is provided with a baffle 24 on the side facing the housing component 12. There is a gap between the baffle 24 and the end face 15. The baffle 24 is fixed to the end face 15 by a connector. The baffle 24 is in surface contact with the locking device 18. A limit block 25 is fixed between the baffle 24 and the end face 15.

[0046] The locking device 18 is provided with a second adjustment port 26 for the limit block 25 to pass through. One end of the elastic element 22 is provided on the limit block 25, and the other end of the elastic element 22 is provided on the locking device 18. The elastic element 22 is located between the limit block 25 and the locking tongue 19.

[0047] In this design, the locking device 18 is located between the baffle 24 and the end face 15, which can prevent the locking device 18 from disengaging. The limiting block 25 can limit the movement distance of the locking device 18 and prevent the movement distance of the locking device 18 from being too large.

[0048] In this design, the limiting block 25 is fixed to the end face 15, so the limiting block 25 cannot move; the locking device 18 is movable and can move in a directional manner under the action of the elastic element 22.

[0049] Furthermore, the elastic element 22 is a compression spring, which continuously provides a thrust to the locking device 18, so that the latch 19 can move to the outside of the side portion 16.

[0050] In one embodiment of this invention, the locking device 18 is provided with a spring mounting cavity 27 that communicates with the second adjustment port 26. The spring mounting cavity 27 is used to accommodate a compression spring. This design is for better installation of the compression spring.

[0051] In one embodiment of this invention, the number of locking devices 18 is two. The two locking devices 18 are symmetrically installed, and the latches 19 in the two locking devices 18 extend in opposite directions. This symmetrical design of the locking devices 18 improves their stability and reliability, forming a double-locking structure. This effectively disperses the lateral force on the latches 19, thereby reducing the probability of damage to the latches 19 and significantly increasing the service life of the locking devices 18.

[0052] As one embodiment of this invention, the housing component 12 is provided with a guide rail limiting structure 17.

[0053] Furthermore, the second end cap 14 is provided with an electrical connection structure, which uses a connector 42 to interface with the battery mounting cavity 29 of the robot.

[0054] Furthermore, a waterproof sealing structure is provided between the first end cap 13 and the housing component 12. The waterproof sealing structure includes a sealing ring 39 or a sealing gasket, etc. The installation position can be selected according to the specific installation structure, and its main purpose is to seal and waterproof.

[0055] Furthermore, the first end cap 13 is provided with a handle 28, which is detachably mounted on the first end cap 13, or the handle 28 is integrally formed with the first end cap 13.

[0056] In addition, this application also proposes a robot having a battery mounting cavity 29 for mounting the aforementioned battery structure; a locking seat 30 is fixed on the robot, and the locking seat 30 has a slot 31 for mounting the locking tongue 19. The battery structure is directly pushed into the battery mounting cavity 29, and the locking tongue 19 automatically locks into the slot 31, offering the advantage of high installation efficiency. During disassembly, the two adjusting parts 20 are manually moved to disengage the locking tongue 19 from the slot 31. When pulling it out, the handle 28 on the first end cover 13 can be pulled, facilitating the lifting and transfer of the battery structure.

[0057] Furthermore, the front end of the battery mounting cavity 29 is provided with a sealing surface 43, which contacts the lower edge surface of the first end cover 13. A sealing gasket is provided on the sealing surface 43 to form a sealing structure with the first end cover 13.

[0058] Furthermore, a guide groove 32 is provided on the inner wall of the battery mounting cavity 29, which is used to install the guide rail limiting structure 17. By providing the guide groove 32 on the inner wall of the battery mounting cavity 29 and providing the corresponding guide rail limiting structure 17 on the battery casing, the battery installation efficiency can be improved.

[0059] Furthermore, the groove depth of the guide groove 32 is set in the horizontal direction; the distance between the inner walls of the two ends of the guide groove 32 in the vertical direction is the opening distance of the guide groove 32, which is the width of the groove.

[0060] like Figure 11 As shown, the left side of the guide groove 32 is the locking section 33, and the right side of the guide groove 32 is the inlet section 34. The opening distance of the locking section 33 is smaller than the opening distance of the inlet section 34.

[0061] Furthermore, such as Figure 12 As shown, the left side of the guide rail limiting structure 17 is the first guide part 35, and the right side of the guide rail limiting structure 17 is the second guide part 36. The height of the first guide part 35 is less than the height of the second guide part 36.

[0062] The first guide portion 35 is used to insert into the locking section 33, and the second guide portion 36 is used to insert into the lead-in section 34.

[0063] The guide groove 32 is designed with locking section 33 and guide section 34 with different opening distances. This variable groove width design makes the vertical movement margin of the battery in the final locked position smaller, which can effectively limit the shaking of the battery after locking, enhance the stability of the connection, and prevent the battery from becoming loose due to vibration during robot movement.

[0064] This solution enables rapid import and positioning of the battery structure, automatic electrical connection, and sealing and locking. It has excellent waterproof performance and structural reliability, and is suitable for warehousing, inspection, and handling robot platforms.

[0065] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
