Description

Technical Field

[0001] This utility model relates to the field of robot battery heat dissipation technology, specifically to a heat dissipation structure for a robot battery compartment. Background Technology

[0002] The robot battery compartment is a core component of the robot's power supply system, primarily used to house and protect the battery pack, ensuring stable robot operation. The battery compartment not only needs to possess good structural strength but also provide stable electrical connections to meet the robot's movement requirements in complex environments.

[0003] However, existing robot battery compartments generate a significant amount of heat during charging and discharging. Poor heat dissipation can lead to decreased battery performance and even safety hazards. Current traditional heat dissipation methods often employ a single air duct or simple ventilation holes, resulting in uneven airflow distribution and low heat dissipation efficiency. Furthermore, the robot's working environment may contain dust, moisture, and other contaminants, which can easily clog heat dissipation channels, further exacerbating the heat dissipation problem. Therefore, there is an urgent need for a highly efficient, dustproof, and structurally optimized battery compartment heat dissipation solution. Utility Model Content

[0027] In this utility model, a positioning plate 6 is provided inside the battery compartment body 1 above the cooling fan 3. Multiple air vents 7 are provided at the edge between the positioning plate 6 and the inside of the battery compartment body 1, and a filter screen 8 is provided at the air vents 7.

[0028] In this utility model, a heightening connecting platform 9 is provided above the positioning plate 6. The heightening connecting platform 9 is connected to the lower end face of the battery pack 2. The heightening connecting platform 9 is provided with contact terminals that are electrically connected to the battery pack 2. The air duct area at the bottom of the battery pack 2 is increased by the heightening connecting platform 9.

[0029] In this utility model, multiple support columns 10 are provided on the inner side of the battery compartment body 1 above the positioning plate 6. The length of the support column 10 is greater than 1 / 2 of the inner height of the battery compartment body 1. The support column 10 is a rectangular structure protruding from the inner wall of the battery compartment body 1. The support columns 10 are arranged in a linear array at equal intervals on the inner wall of the battery compartment body 1. The inner side of the support column 10 abuts against the side of the battery pack 2. A thermally conductive silicone pad 15 is provided on the side of the support column 10 that contacts the battery pack 2. An exhaust hole 11 is provided between adjacent support columns 10. A corresponding second air guide groove 12 is provided on the outer side of the battery compartment body 1 at the exhaust hole 11.
