[0002] Against the backdrop of the rapid development of the global robotics industry, the performance of the power supply system directly determines the robot's operational stability and endurance. As the core power source for robots, the power supply system faces increasingly stringent requirements for safety, reliability, and energy allocation. Currently, battery packs are installed by bolting the battery frame to the housing. Installers must manually align the battery frame with the mounting holes on the housing, a process that requires repeated adjustments to ensure each bolt hole is aligned. This increases installation time and difficulty. Furthermore, due to the lack of pre-positioning, the battery frame is prone to shifting or tilting during installation, leading to inaccurate bolt hole alignment. This not only affects installation efficiency but may also damage the battery frame and housing. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , 2 As shown in Figures 3, 4, 5, 6, and 7, this utility model provides a technical solution: a robot-specific battery pack, comprising: a bottom shell 1, a cavity with an opening at the top of the bottom shell 1, a support plate 3 installed inside the bottom shell 1, the width of the support plate 3 being adapted to the width of the inner wall of the bottom shell 1, preventing the support plate 3 from rotating in the bottom shell 1 after installation, the support plate 3 being made of plastic, a composite plate 5 being fixedly connected to one side of the support plate 3, a battery rack 6 being installed inside the support plate 3, and multiple lithium-ion battery cells 7 being installed in the middle of the battery rack 6. The sub-battery cell 7 is connected by a copper sheet 8, which is a nickel-plated copper sheet. Multiple limiting grooves 13 are equidistantly arranged on the outer side of the battery frame 6. The limiting grooves 13 have a semi-circular structure. The positioning part is placed inside the support plate 3. The positioning part includes multiple positioning posts 14 that are installed on the inner wall of the support plate 3 by screws. An adjustment slot 15 is provided at the end of the positioning post 14 that is away from the composite plate 5. A limiting block 18 for pre-tightening positioning is provided at the top of the adjustment slot 15. The top of the limiting block 18 has an inverted V-shaped structure. An adjustment part is provided at the bottom of the limiting block 18 for pressing and fixing the limiting block 18 upward.

[0024] It should be noted that in this embodiment, after the battery rack 6 and lithium-ion battery cells 7 are combined and installed, multiple lithium-ion battery cells are connected in series through copper sheets 8 to form a high-voltage battery pack. The BMS is connected to the positive and negative terminals of each battery cell through connectors to monitor the voltage and temperature of each battery cell. The combined battery rack 6 and lithium-ion battery cells 7 are installed inside the support plate 3. The limiting groove 13 of the battery rack 6 corresponds to the positioning post 14. The battery rack 6 is pushed into the support plate 3 along the positioning post 14. During the pressing process of the limiting block 18, it retracts downward. When the battery rack 6 is installed inside the support plate 3 and its other end is located on one side of the limiting block 18, the limiting block 18 resets upward. The limiting block 18 is locked by the adjustment part. The limiting block 18 presses and fixes the battery rack 6 in the space formed by the support plate 3 and the composite plate 5, so that its internal structure is integrated to prevent it from shaking. Then the support plate 3 is bolted to the bottom shell 1. Under the limiting of the support plate 3, the internal position of the battery is prevented from shifting.

[0025] In one embodiment, a top cover 2 is fixed to the top of the bottom housing 1. The top cover 2 has heat dissipation vents on its top and sides. A composite plate 11 is fixed to the side of the protective pad 4 away from the composite plate 5. A protective pad 12 is fixed to the outer side of both the composite plate 11 and the composite plate 5. A protective pad 4 is bonded to the outer side of the support plate 3. Both the protective pad 4 and the protective pad 12 are made of ethylene-vinyl acetate copolymer.

[0026] It should be noted that in this embodiment, the top cover 2 and the bottom shell 1 are connected by bolts, thus forming a complete space for accommodating and storing the battery rack 6. Composite plate 5 and composite plate 11 are made of a composite material composed of glass fiber and epoxy resin, providing strong protection for the battery pack through their high mechanical strength, electrical insulation, and heat resistance. Protective pads 4 and 12 are made of EVA, which has good elasticity and impact resistance. They can serve to absorb shocks, reduce vibration, and protect the battery. This prevents damage to the battery from external impacts during transportation, storage, or use.

[0027] In one embodiment, a battery management system 10 is fixedly connected to one end of the battery holder 6, a display 9 is embedded in the outer side of the bottom housing 1, the display 9 is electrically connected to the battery management system 10, and a connector is embedded in the bottom of the bottom housing 1, the connector is electrically connected to the battery management system 10.

[0028] It should be noted that in this embodiment, the BMS is responsible for monitoring the battery status and performing protection and equalization charging functions. The BMS is directly connected to the individual battery cells via connectors. The display 9 is used to display the battery pack's status information. The display 9 is electrically connected to the battery management system 10 to display the data monitored by the BMS. The connection between the display and the BMS uses digital signal transmission, such as I2C or CAN bus protocols. Two connectors are provided: a DELTRON DTS7W2SY / SY4 / 1M86M3 and a Mill-Max Manufacturing Corp. Mill-Max 858-10-004-10-012000. Their function is to provide a connection interface between the external system and the battery management system. They are used to connect external devices, chargers, or other communication interfaces (e.g., for data exchange or power supply). Electrical connection: The electrical connection between the connectors and the battery management system ensures the interaction between the battery pack and external systems (such as chargers, control systems, etc.). The BMS monitors the status of each battery cell, including voltage and temperature, through the connection between the battery rack and the individual battery cells. The display 9 displays this information in real time to help the operator understand the battery's health status. The display exchanges data with the battery management system (BMS) via an electrical connection. The display acquires data from the BMS and displays it on the interface, helping users monitor the battery status in real time. Connectors on the bottom housing 1 provide connections to external devices for charging, data communication, or interfacing with other systems. The electrical connection between the connectors and the BMS allows the entire system to flexibly exchange data or provide power to external devices.

[0029] In one embodiment, the adjustment part includes a threaded rod 16 fixed inside the adjustment slot 15, the top of the threaded rod 16 having a round rod structure, the round rod structure being slidably connected to the limiting block 18, the outer side of the threaded rod 16 being threadedly connected to an adjustment nut 17, and a spring 19 being sleeved on the outer side of the threaded rod 16 and located between the limiting block 18 and the adjustment nut 17.

[0030] It should be noted that in this embodiment, the adjusting nut 17 is first rotated to the bottom of the threaded rod 16, and then the pedal positioning post 14 of the battery holder 6 is slid inward. Because the top of the limiting block 18 is an inverted V-shaped structure, the battery holder 6 presses against the inclined surface of the limiting block 18, causing the limiting block 18 to retract into the adjusting slot 15 and compress the spring 19. When one end of the battery holder 6 is misaligned with the limiting block 18, the limiting block 18 blocks one end of the battery holder 6 under the elastic force of the spring 19. At this time, the adjusting nut 17 is rotated, causing the adjusting nut 17 to compress the spring 19 upward. The spring 19 moves the limiting block 18 upward, so that the side of the limiting block 18 presses against the end of the battery holder 6. Then, thread locking glue is dripped into the connection between the adjusting nut 17 and the threaded rod 16 to prevent the battery holder 6 from loosening.
