Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a battery disassembly and assembly structure and a humanoid robot. Background Technology

[0002] In the field of new energy vehicle batteries, especially two-wheeled vehicle batteries, a certain level of technological accumulation has been achieved, while humanoid robots are gradually emerging as a new development direction. For humanoid robots, the ease of battery installation and removal is a crucial aspect of their use. However, currently, existing battery compartment structures are typically quite simple, presenting certain difficulties in actual installation and removal operations. This, to some extent, affects the user experience and efficiency, failing to adequately meet the needs of humanoid robots in this regard. Therefore, this paper proposes a battery installation and removal structure and a corresponding humanoid robot. Utility Model Content

[0003] The purpose of this invention is to provide a battery disassembly and assembly structure and a humanoid robot to facilitate convenient battery disassembly and assembly.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A battery disassembly and assembly structure, comprising: The battery body has multiple wheel mounting spaces. A caster, wherein multiple casters are installed one-to-one in multiple wheel mounting spaces, each caster includes a housing, a first pivot, a second pivot, a variable force spring, a first transmission wheel, a second transmission wheel, a third transmission wheel, a wheel axle, and a wheel body. The first pivot, second pivot, variable force spring, first transmission wheel, second transmission wheel, third transmission wheel, and wheel axle are disposed in the housing. One end of the variable force spring is connected to the first pivot and the other end is connected to the second pivot. The first transmission wheel, second transmission wheel, and third transmission wheel are respectively connected to the first pivot, second pivot, and wheel axle. The third transmission wheel is drivingly connected to the first transmission wheel and the second transmission wheel. The wheel body is disposed on the wheel axle. The variable force spring has a maximum elastic force point, and the elastic force gradually decreases from the position of the maximum elastic force point to both sides. A battery compartment, in which the battery body is installed, and a cover is provided on the battery compartment.

[0005] In a preferred embodiment, the first drive wheel and the second drive wheel have the same diameter, which is 10-15 times the diameter of the third drive wheel.

[0006] In a preferred embodiment, the first transmission wheel, the second transmission wheel, and the third transmission wheel are all configured as gears, and the third transmission wheel meshes with the circumferences of the first transmission wheel and the second transmission wheel, respectively.

[0007] In a preferred embodiment, the number of wheel mounting spaces is set to four.

[0008] In a preferred embodiment, the wheel body includes a first wheel and a second wheel, which are respectively disposed at both ends of the axle.

[0009] In a preferred embodiment, the housing is provided with a mounting plate, the mounting plate is provided with a mounting through hole, and a mounting screw is provided in the mounting through hole, so that the mounting plate is fixedly installed in the wheel mounting space by the mounting screw.

[0010] A humanoid robot, including the aforementioned battery disassembly and assembly structure.

[0011] Compared with existing technologies, this invention, during battery installation, involves aligning the battery body with the battery compartment and inserting it. During this process, the casters on the battery body contact the inner wall of the battery compartment, causing the casters to rotate under thrust and drive the axle to rotate. The rotation of the axle synchronously drives the third transmission wheel to rotate. Since the third transmission wheel is connected to the first and second transmission wheels, the first and second transmission wheels subsequently drive the first and second rotating shafts to rotate, respectively. At this time, the variable-force spring (coil spring) connecting the first and second rotating shafts is wound around them as the two shafts rotate relative to each other. Its elastic force gradually increases along the winding direction until the battery body is fully inserted into the battery compartment and the cover is closed. At this point, the variable-force spring passes its maximum elastic force point, and the elastic force decreases after reaching its peak. Due to the limitation of the maximum elastic force point, the battery body cannot be pulled out by itself without external force, thus achieving stable locking after installation.

[0012] When removing the battery, after opening the cover, a pulling force is applied to the battery body. When this force overcomes the resistance at the maximum elastic point of the variable force spring, the elastic force of the variable force spring gradually decreases from the peak value to both sides. Its elastic force reacts on the first and second rotating shafts, and drives the axles and wheels to rotate through the transmission of the first, second and third transmission wheels, which helps to push the battery body outward. Combined with the reduced frictional resistance from the rotation of the casters, the battery body can be smoothly removed from the battery compartment.

[0013] This solution reduces frictional resistance during battery installation and removal by utilizing the rotational characteristics of casters, achieving effortless insertion and removal. By leveraging the elasticity variation of variable-force springs, the maximum elasticity point ensures stable locking of the battery after installation, while also improving ease of operation during disassembly through elastic assistance, effectively solving the problem of difficult battery compartment installation and removal in traditional systems.

Detailed Implementation

[0021] The present invention will be further described in detail below with reference to the accompanying drawings.

[0022] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0023] like Figures 1 to 6 As shown, a battery disassembly and assembly structure includes: Battery body 1, wherein the battery body 1 is provided with multiple wheel mounting spaces; Casters 16, a plurality of casters 16 are installed one-to-one in a plurality of wheel mounting spaces. Each caster 16 includes a housing 2, a first rotating shaft 5, a second rotating shaft 6, a variable force spring 7, a first transmission wheel 9, a second transmission wheel 10, a third transmission wheel 11, a wheel axle 12, and a wheel body. The first rotating shaft 5, the second rotating shaft 6, the variable force spring 7, the first transmission wheel 9, the second transmission wheel 10, the third transmission wheel 11, and the wheel axle 12 are disposed in the housing 2. One end of the variable force spring 7 is connected to the first rotating shaft 5, and the other end is connected to the second rotating shaft 6. The first transmission wheel 9, the second transmission wheel 10, and the third transmission wheel 11 are respectively connected to the first rotating shaft 5, the second rotating shaft 6, and the wheel axle 12. The third transmission wheel 11 is connected to the first transmission wheel 9 and the second transmission wheel 10 respectively. The wheel body is disposed on the wheel axle 12. The variable force spring 7 has a maximum elastic force point 8, and the elastic force gradually decreases from the position of the maximum elastic force point 8 to both sides. Battery compartment 15, in which the battery body 1 is installed, and the battery compartment 15 is provided with a cover (not shown in the figure).

[0024] In this embodiment, a battery installation and removal structure involves aligning the battery body 1 with the battery compartment 15 during installation. During this process, the casters 16 on the battery body 1 contact the inner wall of the battery compartment 15, causing the casters to rotate under thrust and drive the axle 12 to rotate. The rotation of the axle 12 synchronously drives the third transmission wheel 11 to rotate. Since the third transmission wheel 11 is connected to the first transmission wheel 9 and the second transmission wheel 10, the first transmission wheel 9 and the second transmission wheel 10 subsequently drive the first rotating shaft 5 and the second rotating shaft 6 to rotate, respectively. At this time, the variable force spring 7 (a spiral spring) connecting the first rotating shaft 5 and the second rotating shaft 6 is wound around the two shafts as they rotate relative to each other. Its elastic force gradually increases along the winding direction until the battery body 1 is fully inserted into the battery compartment 15 and the cover is closed. At this point, the variable force spring 7 passes through the maximum elastic force point 8, and the elastic force decreases after reaching its peak. Due to the limitation of the maximum elastic force point 8, the battery body 1 cannot be pulled out by itself without external force, thus achieving stable locking after installation.

[0025] When disassembling the battery, after opening the cover, a pulling force is applied to the battery body 1. When the force overcomes the resistance of the maximum elastic point 8 of the variable force spring 7, the elastic force of the variable force spring 7 gradually decreases from the peak value to both sides. Its elastic force reacts to the first rotating shaft 5 and the second rotating shaft 6. Through the transmission of the first transmission wheel 9, the second transmission wheel 10, and the third transmission wheel 11, the wheel axle 12 and the wheel body rotate, which helps to push the battery body 1 to move outward. With the reduced frictional resistance caused by the rotation of the caster 16, the battery body 1 can be smoothly removed from the battery compartment 15.

[0026] This solution reduces frictional resistance during battery installation and removal by utilizing the rotational characteristics of the caster 16, achieving effortless insertion and removal. By leveraging the elasticity variation characteristics of the variable force spring 7 and utilizing the maximum elasticity point 8, it ensures stable locking after battery installation and improves operational convenience during disassembly through elastic assistance, effectively solving the problem of difficult installation and removal of the traditional battery compartment 15.

[0027] The first transmission wheel 9 and the second transmission wheel 10 have the same diameter, which is 10-15 times the diameter of the third transmission wheel 11. During transmission, due to the large diameter difference between the first and second transmission wheels 10 and the third transmission wheel 11, the number of rotations of the first and second transmission wheels 10 will decrease significantly when the third transmission wheel 11 rotates a certain number of times. The winding degree of the variable force spring 7 is directly related to the number of rotations of the first and second rotating shafts 6. Fewer rotations mean that the variable force spring 7 does not need to be too long to achieve the required elastic force change effect, especially to meet the elastic force requirement of the maximum elastic force point 8. In this way, while ensuring that the variable force spring 7 functions properly, its length can be significantly shortened, thereby reducing the installation space required inside the caster 16 housing 2, realizing the miniaturization design of the caster 16, so that the wheel installation space on the battery body 1 does not need to be too large, which is conducive to the compact layout of the overall structure and improves space utilization.

[0028] In order to achieve stable engagement of the first transmission wheel 9, the second transmission wheel 10 and the third transmission wheel 11, the first transmission wheel 9, the second transmission wheel 10 and the third transmission wheel 11 are all configured as gears, and the third transmission wheel 11 meshes with the circumference of the first transmission wheel 9 and the second transmission wheel 10 respectively.

[0029] In this embodiment, the number of wheel mounting spaces is set to 4.

[0030] To achieve a stable wheel configuration, the wheel includes a first wheel 13 and a second wheel 14, which are respectively located at both ends of the axle 12.

[0031] To facilitate the installation of the caster 16, the housing 2 is provided with a mounting plate 3, the mounting plate 3 is provided with a mounting through hole 4, and a mounting screw is provided in the mounting through hole 4. The mounting plate 3 is fixedly installed in the wheel mounting space by the mounting screw. Example

[0032] A humanoid robot includes the battery disassembly and assembly structure described in Embodiment 1, to improve the convenience of battery disassembly and assembly in the humanoid robot.

[0033] The above description of the embodiments is provided to facilitate understanding and use of the present invention by those skilled in the art. It is obvious to those skilled in the art that various modifications can be easily made to the embodiments, and the general principles described herein can be applied to other embodiments without creative effort. Therefore, the present invention is not limited to the above embodiments. Any improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the present invention should be within the protection scope of the present invention.
