Description

Technical Field

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

[0002] With the continuous development of new energy technologies, batteries, as core energy supply components, are widely used in various electric devices, with mature applications already achieved in the two-wheeled vehicle sector. The performance and lifespan of a battery largely depend on its operating environment temperature. If heat cannot be dissipated in time, the battery temperature will become too high, affecting not only its output efficiency but also potentially causing safety hazards. Currently, some battery compartment designs for two-wheeled vehicles lack dedicated heat dissipation structures, relying solely on the battery compartment's materials and structure for natural heat dissipation. This method is inefficient and fails to meet the battery's cooling requirements under high loads. Other products use fans for cooling, but forced ventilation via fans often results in uneven heat dissipation and inefficient heat dissipation paths, leading to limited cooling effectiveness. This fails to efficiently dissipate the heat generated by the battery, negatively impacting battery performance and lifespan. With the rise of humanoid robot technology, higher demands have been placed on battery energy density and continuous working time, leading to a corresponding increase in the heat generated by batteries during operation. Existing humanoid robot battery compartment designs largely reference the structures of traditional equipment, often lacking dedicated heat dissipation structures or relying solely on simple fans for cooling. The heat dissipation effect needs further improvement and is insufficient to meet the stringent heat dissipation requirements of humanoid robots, thus hindering their stable operation and performance.

[0003] In view of this, a heat dissipation structure, a battery compartment, and a humanoid robot are proposed. Utility Model Content

[0004] The purpose of this invention is to provide a heat dissipation structure, a battery compartment, and a humanoid robot to improve heat dissipation.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A heat dissipation structure, comprising: The battery body has multiple wheel mounting spaces. Casters, with multiple casters installed one-to-one in multiple wheel mounting spaces; The wheel rails are provided with at least two parallel rails, and the lower surface of the wheel rails is provided with multiple heat dissipation fins.

[0006] In a preferred embodiment, the wheel and rail are made of aluminum alloy.

[0007] In a preferred embodiment, the caster includes two or more wheel bodies, and the wheel rail is provided with wheel grooves corresponding to the wheel bodies.

[0008] In a preferred embodiment, the caster includes a housing, a first pivot, a second pivot, a variable-force spring, a first drive wheel, a second drive wheel, a third drive wheel, an axle, and a wheel body. The first pivot, second pivot, variable-force spring, first drive wheel, second drive wheel, third drive wheel, and 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 drive wheel, second drive wheel, and third drive wheel are respectively connected to the first pivot, second pivot, and axle. The third drive wheel is drivingly connected to the first drive wheel and the second drive wheel. The wheel body is disposed on the 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.

[0009] 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.

[0010] 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.

[0011] In a preferred embodiment, the number of wheel mounting spaces is set to four.

[0012] 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.

[0013] A battery compartment includes the aforementioned heat dissipation structure, the wheel rail is disposed at the bottom of the battery compartment, and the battery compartment is provided with a cover.

[0014] A humanoid robot includes the aforementioned heat dissipation structure or the aforementioned battery compartment.

[0015] Compared to existing technologies, this invention utilizes the coordination between the casters and the wheel mounting space. The casters effectively lift the battery body slightly, creating a heat dissipation space inside the battery compartment. Simultaneously, multiple heat dissipation fins on the lower surface of the wheel rails increase the heat dissipation area. The contact between the fins and the air achieves efficient heat exchange, conducting the heat generated by the battery operation to the fins via the wheel rails and then dissipating it to the outside of the battery compartment, preventing heat accumulation inside. This synergistic effect of the above structures optimizes the heat dissipation environment through the raised heat dissipation space and enhances the heat dissipation capacity through the heat dissipation fins. Compared to existing methods without dedicated heat dissipation structures or relying solely on fans, this significantly improves the overall heat dissipation effect of the battery compartment, helping to maintain the stability of the battery's operating temperature and ensuring battery performance and lifespan.

Detailed Implementation

[0023] The present invention will be further described in detail below with reference to the accompanying drawings.

[0024] 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. Example

[0025] like Figures 2 to 6 As shown, a heat dissipation structure includes: Battery body 1, wherein the battery body 1 is provided with multiple wheel mounting spaces; Casters 13, a plurality of casters 13 are installed one-to-one in a plurality of wheel mounting spaces; The wheel rail 16 has at least two parallel rails, and the lower surface of the wheel rail 16 has multiple heat dissipation fins 17.

[0026] In this embodiment, a heat dissipation structure utilizes the interaction between the casters 13 and the wheel mounting space. The casters 13 effectively lift the battery body 1 slightly, creating a heat dissipation space inside the battery compartment 15. Simultaneously, multiple heat dissipation fins 17 on the lower surface of the wheel rail 16 increase the heat dissipation area. Efficient heat exchange is achieved through the contact between the fins and the air, conducting the heat generated by the battery operation to the fins via the wheel rail 16 and then conducting it outwards to the outside of the battery compartment 15, preventing heat accumulation inside the battery compartment 15. The synergistic effect of these structures optimizes the heat dissipation environment through the raised heat dissipation space and enhances the heat dissipation capacity with the heat dissipation fins 17. Compared to existing methods without a dedicated heat dissipation structure or relying solely on fan cooling, this significantly improves the overall heat dissipation effect of the battery compartment 15, helping to maintain the stability of the battery's operating temperature and ensuring battery performance and lifespan.

[0027] To ensure effective heat dissipation, the wheel rail 16 is made of aluminum alloy.

[0028] In order to improve the stability of the caster 13 during movement and improve the heat conduction efficiency of the wheel rail 16, the caster 13 includes two or more wheel bodies 14, and the wheel rail 16 is provided with wheel grooves 18 corresponding to the wheel bodies 14.

[0029] The caster 13 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, an axle 12, and a wheel body 14. 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 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 axle 12. The third transmission wheel 11 is connected to the first transmission wheel 9 and the second transmission wheel 10 in a transmission connection. The wheel body 14 is disposed on the 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.

[0030] With the above structural configuration, during battery installation, the battery body 1 is aligned with the battery compartment 15 and inserted. During this process, the casters 13 on the battery body 1 contact the inner wall of the battery compartment 15, causing the wheel 14 to rotate under the thrust, which in turn drives 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 respectively, 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 (coil spring) connecting the first rotating shaft 5 and the second rotating shaft 6 is wound around the two rotating 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 value. Due to the limitation of the maximum elastic force point 8, the battery body 1 cannot be pulled out by itself under the elastic force of the variable force spring 7 without external force, thus achieving stable locking after installation.

[0031] 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 14 are driven to rotate, which helps to push the battery body 1 to move outward. With the reduced frictional resistance caused by the rotation of the caster 13, the battery body 1 can be smoothly removed from the battery compartment 15.

[0032] The rotation characteristics of the caster 13 reduce the frictional resistance during battery installation and removal, achieving a labor-saving effect when inserting and removing the battery. By utilizing the elasticity variation characteristics of the variable force spring 7 and the maximum elasticity point 8, the battery is not only stably locked after installation, but also the operation is made easier during disassembly through the elasticity assistance, effectively solving the problem of difficult installation and disassembly of the traditional battery compartment 15.

[0033] 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 with the wheel body 14. The degree of winding 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 13 housing 2, realizing the miniaturization design of the caster 13, 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.

[0034] 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.

[0035] In this embodiment, the number of wheel mounting spaces is set to 4.

[0036] To facilitate the installation of the caster 13, 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

[0037] like Figures 1 to 6 As shown, a battery compartment 15 includes the heat dissipation structure described in Embodiment 1. The wheel rail 16 is located at the bottom of the battery compartment 15, and the battery compartment 15 is provided with a cover (not shown in the figure) to achieve efficient heat dissipation of the battery compartment 15.
