Description

Technical Field

[0001] This utility model relates to the field of humanoid robot technology, specifically a humanoid robot with a dual-battery pack power supply system. Background Technology

[0002] Humanoid robots are widely used in daily life and industrial production. As a product of multidisciplinary integration, they involve multiple disciplines such as bionics, control engineering, electronic information, and computer science. They can also be used as experimental teaching platforms. Currently, humanoid robots are powered by a single battery pack. When the battery pack runs out of power and needs to be replaced, the entire humanoid robot system is powered off. Restarting and restoring it to its original state takes a long time. At the same time, when the humanoid robot is powered off, the machine is lying on the ground and requires multiple people to maintain and operate it.

[0003] For example, the patent with authorization announcement number CN208433452U describes a battery pack and a robot having the battery pack, including a shell, a battery pack and a hub. The battery pack is located inside the shell, and is integrated by setting up conductive bars and a hub before being connected to the power management unit. However, it is powered by a single battery pack. When the battery pack is depleted and needs to be replaced, the entire humanoid robot system is powered off. Restarting and restoring it to its original state takes a long time. At the same time, when the humanoid robot is powered off, the machine is lying on the ground, requiring multiple people to maintain and operate it, which is quite troublesome and reduces the practicality of the device.

[0004] Based on this, a humanoid robot with a dual-battery pack power supply system is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0005] The purpose of this invention is to provide a humanoid robot with a dual-battery pack power supply system to solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A humanoid robot with a dual-battery-pack power supply system includes a robot torso. The outer wall of the robot torso has two identical placement slots, in which battery pack bodies are placed. The outer wall of the battery pack bodies is provided with an unlocking mechanism, and the inner wall of the robot torso is provided with a fixing mechanism.

[0007] Based on the above technical solutions, this utility model also provides the following optional technical solutions: Preferably, the battery pack body has symmetrically formed grooves, a baffle is fixedly connected in the groove, and a top block is slidably connected in the groove. The top block has a rectangular cross-section with rounded corners, and a through groove is formed on the outer wall of the top block.

[0008] Preferably, an elastic sheet is fixedly connected to the inner sidewall of the top block, and the outer wall of the elastic sheet overlaps with the outer wall of the baffle.

[0009] Preferably, the unlocking mechanism includes a turntable, which is slidably connected to a circular groove on the outer wall of the battery pack body. Insert rods are evenly distributed and fixedly connected to the outer wall of the turntable, and insert blocks are symmetrically fixedly connected to the outer wall of the turntable. The insert blocks are arc-shaped.

[0010] Preferably, the insert rod is fixedly connected to a rotating block by bolts, and the arc-shaped groove on the outer wall of the rotating block is inserted into the insert block. The insert block and the rotating block are fixed together by bolts, and the outer wall of the rotating block abuts against the outer wall of the top block.

[0011] Preferably, the outer wall of the rotating block is evenly distributed with arc-shaped protrusions, and the connection between the protrusions and the rotating block is provided with rounded corners.

[0012] Preferably, the fixing mechanism includes a mounting plate, on which springs are uniformly fixedly connected to the outer wall of the mounting plate. The ends of the springs are fixedly connected to the inner sidewall of the robot torso. Limiting blocks are fixedly connected to the outer wall of the mounting plate. The limiting blocks are inserted into slots opened on the inner sidewall of the robot torso and into sliding grooves opened on the battery pack body. The ends of the limiting blocks abut against the outer wall of the top block.

[0013] Preferably, the cross-section of the portion connecting the limiting block and the groove on the battery pack body is trapezoidal, and the inclined surface faces the insertion direction of the battery pack body.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention, through the cooperation of a baffle, a top block, an elastic sheet, an unlocking mechanism, and a fixing mechanism, enables rapid replacement and installation of battery packs on the robot without causing it to collapse. When installing the two battery packs, the fixing mechanism secures them, preventing them from falling. If both battery packs are below a certain voltage threshold, the robot will automatically prompt for replacement without power loss. At this point, the unlocking mechanism drives the top block, which pushes out the limiting block in the fixing mechanism, releasing the restriction on the battery packs, allowing for disassembly and replacement.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] Example 1 In one embodiment, such as Figures 1-8 As shown, a humanoid robot with a dual-battery-pack power supply system includes a robot torso 1. The outer wall of the robot torso 1 has two identical placement slots, in which a battery pack body 11 is placed. The outer wall of the battery pack body 11 is provided with an unlocking mechanism 2, and the inner wall of the robot torso 1 is provided with a fixing mechanism 3.

[0026] In this embodiment, the fixing mechanism 3 can fix the two battery pack bodies 11 installed in the robot torso 1 to prevent them from falling off. When replacing one of the battery pack bodies 11, the fixing mechanism 2 can be used to remove the fixing effect of the fixing mechanism 3, and the battery pack body 11 can be taken out. The battery pack body 11 with depleted power can be taken out, while the other battery pack body 11 can continue to work, thus preventing the robot from collapsing to the ground when replacing the battery pack body 11.

[0027] In an optional embodiment, such as Figure 2 and Figure 3As shown, the battery pack body 11 has symmetrically arranged grooves. A baffle 12 is fixedly connected in the groove, and a top block 13 is slidably connected in the groove. The cross-section of the top block 13 is a rectangle with rounded corners, and a through groove is opened on the outer wall of the top block 13. An elastic piece 14 is fixedly connected to the inner side wall of the top block 13. The outer wall of the elastic piece 14 overlaps with the outer wall of the baffle 12. The top block 13 is driven to move by the unlocking mechanism 2, so that the top block 13 can push the fixing mechanism 3 out of the groove, thereby canceling the fixing effect of the fixing mechanism 3 on the battery pack body 11. Then the battery pack body 11 can be taken out from the placement groove. After taking it out, the unlocking mechanism 2 is restored to its original state. At this time, under the action of the elastic piece 14, the top block 13 is driven to slide in the groove, so that the top block 13 returns to its original position.

[0028] In an optional embodiment, such as Figure 3 As shown, the unlocking mechanism 2 includes a turntable 21, which is slidably connected to a circular groove on the outer wall of the battery pack body 11. Insert rods 22 are evenly distributed and fixedly connected to the outer wall of the turntable 21. Insert blocks 23 are symmetrically fixedly connected to the outer wall of the turntable 21. The insert blocks 23 are arc-shaped. A rotating block 24 is fixedly connected to the insert rods 22 by bolts. An arc-shaped groove on the outer wall of the rotating block 24 engages with the insert block 23. The insert block 23 and the rotating block 24 are fixed together by bolts. The outer wall of the rotating block 24 abuts against the outer wall of the top block 13. Arc-shaped protrusions are evenly distributed on the outer wall of the rotating block 24, and rounded corners are provided at the connection points between the protrusions and the rotating block 24. Rotating the turntable 21 drives the fixed... The insert rod 22 and insert block 23 on it rotate synchronously; the insert block 23 is embedded in the arc-shaped groove of the rotating block 24, thereby driving the rotating block 24 to rotate around its axis, so that the arc-shaped protrusion on the outer wall of the rotating block 24 abuts against the outer wall of the top block 13, driving the top block 13 to slide in the sliding groove opened on the outer wall of the battery pack body 11, so that the top block 13 drives the elastic sheet 14 to move synchronously, and the elastic sheet 14 deforms under the obstruction of the baffle 12. At the same time, the top block 13 pushes the limiting block 32 to move, driving the spring 33 to stretch, so that the limiting block 32 exits the sliding groove and no longer restricts the battery pack body 11. Then the battery pack body 11 can be taken out from the placement slot and replaced.

[0029] In an optional embodiment, such as Figure 3 and Figure 4As shown, the fixing mechanism 3 includes a mounting plate 31. Springs 33 are uniformly fixedly connected to the outer wall of the mounting plate 31. The ends of the springs 33 are fixedly connected to the inner side wall of the robot body 1. Limiting blocks 32 are fixedly connected to the outer wall of the mounting plate 31. The limiting blocks 32 are inserted into slots opened in the inner side wall of the robot body 1 and into sliding grooves opened on the battery pack body 11. The ends of the limiting blocks 32 abut against the outer wall of the top block 13. When installing two battery pack bodies 11 of the same size, the limiting blocks 32 are installed sequentially. During installation, the outer wall of the battery pack body 11 contacts the inclined surface of the limiting block 32, causing the limiting block 32 to retract automatically. The limiting block 32 drives the mounting plate 31 to move, causing the spring 33 to stretch. When the battery pack body 11 is fully inserted into the placement slot, under the action of the spring 33, the limiting block 32 engages with the sliding groove opened on the outer wall of the battery pack body 11 and abuts against the outer wall of the top block 13, thereby limiting and fixing the battery pack body 11, preventing the battery pack body 11 from sliding out of the placement slot.

[0030] In an optional embodiment, such as Figure 3 and Figure 4 As shown, the cross-section of the connecting part of the limiting block 32 and the sliding groove on the battery pack body 11 is trapezoidal, and the inclined surface faces the insertion direction of the battery pack body 11. The inclined surface of the limiting block 32 makes the battery pack body 11 easier to install.

[0031] In an optional embodiment, such as Figure 7 As shown, either battery pack one or battery pack two controls the switching of its output MOSFETs via its internal battery management IC (BMS IC). The system's main control MCU collects the voltages of battery pack one and battery pack two in real time through a voltage divider resistor circuit. According to the set logic algorithm, the MCU controls the operating state of battery pack one and battery pack two (such as primary / standby switching). If the voltages of both battery packs are lower than the set threshold, the system will automatically trigger a low battery replacement prompt, but the entire unit can still maintain power supply (relying on the remaining power or the minimal superposition of the power of the two battery packs), avoiding shutdown when replacing either battery pack.

[0032] Example 2 In an optional embodiment, such as Figure 1 and Figure 6As shown, the outer wall of the robot body 1 has a placement slot that can accommodate two battery packs of different sizes (e.g., a standard battery pack body 11 and a small battery pack). The small battery pack has a positioning groove. The outer wall of the standard battery pack body 11 is equipped with an unlocking mechanism 2, and the inner wall of the robot body 1 is equipped with a fixing mechanism 3. During installation, the small battery pack is first placed into the placement slot, so that the positioning groove of the small battery pack is connected to the positioning rail in the placement slot. Then, the standard battery pack body 11 is installed, and the standard battery pack body 11 is positioned against the small battery pack. Then, the fixing mechanism 3 is used to fix the standard battery pack body 11 to prevent it from falling off, thus completing the installation.

[0033] The above embodiment discloses a humanoid robot with a dual-battery pack power supply system. When installing the two battery pack bodies 11 into the placement slots on the robot's torso 1, the two battery pack bodies 11 are sequentially kept at the same height and horizontal with the upper and lower placement slots. Then, the two battery pack bodies 11 are sequentially pushed into the placement slots, causing the outer wall of the battery pack body 11 to contact the inclined surface of the limiting block 32. This causes the limiting block 32 to automatically retract, and the limiting block 32 drives the mounting plate 31 to move, stretching the spring 33. When the battery pack bodies... When the battery pack body 11 is fully inserted into the placement slot, under the action of the spring 33, the limiting block 32 engages with the sliding groove on the outer wall of the battery pack body 11 and abuts against the outer wall of the top block 13, thereby limiting and fixing the battery pack body 11, preventing it from sliding out of the placement slot. When the battery pack body 11 needs to be replaced, the turntable 21 is rotated, causing the insertion rod 22 and the insertion block 23 fixed thereon to rotate synchronously; the insertion block 23 is embedded in the arc-shaped groove of the rotating block 24, thereby causing the rotating block 24 to rotate around its axis, so that the rotating block 23... The arc-shaped protrusion on the outer wall of the battery pack body 11 presses against the outer wall of the top block 13, thereby driving the top block 13 to slide within the groove on the outer wall of the battery pack body 11. This causes the top block 13 to move synchronously with the elastic sheet 14. The elastic sheet 14 deforms under the obstruction of the baffle 12. At the same time, the top block 13 pushes the limiting block 32 to move, causing the spring 33 to stretch and the limiting block 32 to exit the groove, no longer restricting the battery pack body 11. Then, the battery pack body 11 can be removed from the placement slot and replaced. Afterward, the turntable 21 is rotated in the opposite direction to rotate... Block 24 returns to its original position, and under the elastic force of the elastic sheet 14, the top block 13 returns to its original position simultaneously. When one of the battery pack bodies 11 is removed, the other battery pack body 11 continues to work, thus ensuring that the robot will not collapse when the battery pack body 11 is replaced, thereby achieving the effect of convenient battery pack replacement. In summary, the dual battery packs are reliably fixed by the fixing mechanism 3, and the single battery pack is safely and quickly replaced by the unlocking mechanism 2, effectively avoiding the problem of robot power failure and shutdown during the replacement process.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
