Description

Technical Field

[0001] This invention relates to the field of interactive robot technology, and in particular to an intelligent interactive humanoid robot. Background Technology

[0002] With the rapid development of intelligent equipment and human-computer interaction technology, intelligent interactive humanoid robots have been widely used in service guidance, security inspection, industrial operations, and special scenario operations, placing increasingly higher demands on the continuous working capability of these devices. As a core component of humanoid robots, the power supply module currently mostly adopts a single-battery direct-supply structure in conventional designs. Although some products are equipped with dual battery packs, they generally rely on simple plug-and-play and manual switching, lacking automated docking, stable locking, and synchronous protection and heat dissipation designs, making it difficult to simultaneously meet the requirements of long battery life, high reliability, and convenient maintenance.

[0003] A search revealed a Chinese patent for an intelligent interactive humanoid robot (publication number: CN109877845B). This technology utilizes a combination of a metal ring, a battery, a plastic plate, a spring, a cam, a slide bar, and a spring plate to switch power to another battery pack when a single battery is about to run out of power. This alleviates the problem of insufficient power in emergency situations and improves the robot's overall endurance.

[0004] However, this structure has obvious defects in actual use. After long-term and frequent switching, the spring is prone to wear and deformation, resulting in poor contact with the battery terminal. At the same time, the vibration generated during the humanoid robot's walking will cause the spring to shake and shift, which can easily cause the connection with the battery terminal to loosen or break instantly, causing the robot to suddenly lose power, seriously affecting the stability of operation and safety of use. There is a need to design an intelligent interactive humanoid robot to solve the problems mentioned above. Summary of the Invention

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: an intelligent interactive humanoid robot, including a robot cavity, wherein battery pack connection units are provided on the upper and lower parts of the inner side of the robot cavity, cooling units are provided on the left and right ends of the outer side of the robot cavity, and a middle partition is welded to the middle part of the inner side of the robot cavity; Each battery pack connection unit includes a drive motor and a lifting plate. The upper end of each drive motor is fixedly connected to a drive gear. The left front part and the right rear part of each lifting plate are fixedly connected to a first threaded sleeve. Each first threaded sleeve is threadedly engaged with a threaded screw. The bottom of each threaded screw is fixedly provided with a driven gear. Each driven gear meshes with the corresponding drive gear. Each of the lifting plates is equipped with a battery pack assembly on its upper part. Each of the battery pack assemblies has a battery pack electrode protrusion on its upper rear side. Each of the battery pack assemblies is also equipped with a battery pack access plate on its upper part. The battery pack access plates are respectively fixed to the top of the inner side of the robot cavity and the bottom of the middle partition. Each of the battery pack access plates has an access slot on its bottom rear side. After the battery pack electrode protrusions move upward, they are inserted and docked with the corresponding access slots. The robot cavity has battery inlet and outlet slots on the upper and lower front sides. The upper part of each battery inlet and outlet slot has a raised anti-collision groove. The battery pack and the battery pack electrode protrusions on its upper part are pushed into the robot cavity after being inserted into the corresponding battery inlet and outlet slots and the middle partition. The drive motor's rotating shaft is also fixedly connected to a horizontal bevel gear. The upper and lower ends of the robot cavity are rotatably provided with bidirectional screws located at the bottom of the lifting plate. The middle of each bidirectional screw is fixedly connected to a vertical bevel gear. Each vertical bevel gear meshes with a corresponding horizontal bevel gear. The left and right ends of each bidirectional screw are threadedly connected to a second threaded sleeve. The upper end of each second threaded sleeve is fixedly connected to a clamping rubber plate.

[0006] Preferably, sleeves are welded to the rear left side and the front right side of the lifting plate, and guide sliding columns are provided on the inner side of the sleeves. The bottom of each threaded screw is provided with a first bearing seat, which is fixedly connected to the bottom of the corresponding robot cavity and the upper part of the middle partition plate. The left and right ends of the bidirectional screw are both fixedly connected to a second bearing seat.

[0007] By adopting the above technical solution, the lifting plate can achieve vertical and stable lifting with the cooperation of the sleeve and the guide sliding column, avoiding skewing and jamming during the lifting process, and ensuring precise docking of the battery pack electrode protrusions with the access slot; at the same time, the first bearing seat can effectively reduce the frictional resistance when the threaded screw rotates, improve transmission efficiency, reduce the load on the drive motor, and extend the service life of the transmission components.

[0008] Preferably, the battery pack access plate is provided with rod mounting slots on the left and right sides and the front and rear sides. The bottom ends of the threaded screw and the guide sliding column are respectively fixedly connected to the bottom of the corresponding robot cavity and the upper part of the middle partition. The upper ends of the threaded screw and the guide sliding column are respectively fixedly connected to the inner side of the corresponding rod mounting slot. The robot cavity is provided with insertion slots on the upper front and middle sides. After the battery pack access plate is inserted into the insertion slots, it is fixed to the robot cavity with bolts.

[0009] By adopting the above technical solution, both ends of the threaded screw and the guide sliding column are reliably fixed, resulting in higher rigidity and smoother operation of the overall lifting mechanism, without any shaking or loosening. The battery pack access plate is installed through the insertion slot, which improves assembly accuracy and fixation, facilitates later disassembly and maintenance, and ensures long-term stability and reliability of the power supply structure.

[0010] Preferably, a rear cover plate is fixedly connected to the rear side of the robot cavity by bolts; Motor mounting slots are provided on the bottom center of the robot cavity and the upper center of the middle partition plate, and the drive motors are respectively fixedly connected to the inner side of the corresponding motor mounting slots.

[0011] By adopting the above technical solutions, the rear cover plate facilitates the installation, debugging, and maintenance of internal components of the robot cavity; the drive motor is positioned and installed through the motor fixing slot, which can effectively reduce motor vibration, ensure stable meshing between the drive gear and the driven gear, and improve transmission reliability.

[0012] Preferably, the upper front side of the battery pack is fixedly connected to a first sealing plate by bolts. After the first sealing plate rises with the battery pack, it seals and covers the protruding anti-collision groove. A second sealing plate is welded to the front side of each lifting plate. After the second sealing plate rises with the lifting plate, it seals and covers the battery inlet / outlet slot.

[0013] By adopting the above technical solution, the first sealing plate and the second sealing plate can automatically complete the sealing during the lifting action, respectively sealing the raised anti-collision groove and the battery inlet / outlet groove, effectively preventing dust and moisture from entering the robot cavity, improving the overall dustproof, waterproof and anti-collision capabilities, and enhancing the robot's adaptability and safety in complex environments.

[0014] Preferably, a first rubber pad is glued and fixedly installed on both the upper left and right sides of the battery pack assembly. After the first rubber pad rises with the battery pack assembly, it abuts against the bottom of the battery pack access plate. The upper part of each drive gear is fixedly provided with a protective plate, and the four corners of the protective plate are provided with clearance grooves. Several second rubber pads are equidistantly bonded to the upper part of the protective plate. After the lifting plate is lowered, it is respectively mounted on the upper part of the corresponding second rubber pad.

[0015] By adopting the above technical solution, the first rubber pad acts as a buffer stop to avoid rigid collision between the battery pack and the battery pack access plate, while improving contact sealing and insulation; the protective plate can protect the gear transmission structure below, and the second rubber pad provides soft landing support for the lifting plate, reducing impact, noise and wear, and extending the service life of the mechanism.

[0016] Preferably, the cooling unit includes a miniature air pump fixedly connected to the middle of the left and right sides of the robot cavity. The cooling unit also includes eight diffuser connecting sleeves disposed at the four corners of the left and right sides of the robot cavity. Each diffuser connecting sleeve has a vortex air duct fixedly disposed at its outer end. Each vortex air duct has an air inlet connecting pipe connected to its outer side. Each air inlet connecting pipe is connected to the miniature air pump on the corresponding side through a connecting head.

[0017] By adopting the above technical solution, the micro air pump, together with the vortex air duct and the diffuser connecting sleeve, forms a multi-point distributed cooling air path, which can simultaneously and evenly dissipate heat from the upper and lower battery packs, quickly remove working heat, avoid battery degradation at high temperatures, and improve battery discharge performance, range and long-term operational stability.

[0018] Preferably, annular insertion slots are provided at the four corners of the left and right sides of the robot cavity, and retaining rings are provided on the inner side of the diffusion connecting sleeve, and the retaining rings are respectively engaged and connected to the inner side of the corresponding annular insertion slots. The outer side of each diffusion connecting sleeve is welded with a side lug, and the side lug is fixedly connected to the robot cavity by bolts.

[0019] By adopting the above technical solution, the diffusion connector sleeve is quickly positioned and snapped into place by the retaining ring and the annular insertion groove, making assembly convenient and connection tight; the side ears are further reinforced to ensure that the cooling pipes do not loosen or leak air under the vibration of the robot's operation, thus ensuring a continuous, stable and reliable cooling effect.

[0020] In summary, the present invention provides an intelligent interactive humanoid robot with the following beneficial effects: 1. This invention adopts an independently arranged structure of dual battery packs on the upper and lower sides of the robot cavity. With the linkage transmission of the drive motor, drive gear, driven gear, threaded screw and lifting plate in the battery pack connection unit, the upper and lower battery packs can be automatically raised and lowered and seamlessly alternated in power supply. This avoids robot shutdown caused by power interruption of a single battery. At the same time, combined with the quick-connect structure design of the battery slot, the battery pack can be directly pushed in and pulled out for replacement without disassembling the whole machine. At night, the battery can be charged directly without removing it. While improving the battery life, it significantly enhances the convenience of battery maintenance, replacement and charging, meeting the needs of long-term, high-frequency intelligent interactive operation.

[0021] 2. This invention uses a lifting plate, a first threaded sleeve, a threaded screw, a sleeve, and a guide sliding column to form a high-precision lifting and guiding mechanism. The threaded transmission has good self-locking properties, and with the limit correction of the guide sliding column, the lifting plate does not shake, deviate, or jam during the lifting process. This ensures that the battery pack electrode protrusions on the battery pack are accurately aligned and stably connected with the access slots on the battery pack access plate, and that the power supply contact is reliable and without any gaps. The first bearing seat reduces the rotation resistance of the screw, and the rod mounting slot fixes the upper and lower ends of the screw and the sliding column. The overall structure has high rigidity and runs smoothly, greatly improving the stability, durability, and overall reliability of the power supply system.

[0022] 3. This invention utilizes a follow-up sealing structure consisting of a first sealing plate, a second sealing plate, a battery pack assembly, and a lifting plate. After the battery pack assembly rises to its position, the first sealing plate automatically covers the raised anti-collision groove, and the second sealing plate automatically seals the battery inlet / outlet groove, forming a fully enclosed sealed protection. This effectively prevents dust, moisture, and debris from entering the robot's cavity. Simultaneously, in conjunction with the first rubber pad for buffering and the second rubber pad for soft landing and shock absorption, it reduces the rigid impact between the battery pack assembly and the battery pack access plate, and between the lifting plate and the protective plate. This protects the electrodes and transmission structure from collision damage, significantly improving the overall dustproof, waterproof, and anti-collision capabilities and safety protection level of the machine.

[0023] 4. This invention uses a micro air pump, air inlet connecting pipe, vortex air duct and diffuser connecting sleeve of the cooling unit to form a multi-point distributed vortex cooling system. It forms a uniform air path at the four corners of the left and right sides of the robot cavity, which can simultaneously and efficiently dissipate heat from the upper and lower battery packs, quickly remove the heat generated by battery charging and discharging, and avoid battery high temperature degradation, overheat protection or shortened life. The diffuser connecting sleeve is double fixed by the retaining ring and side ear, and the connection is firm and airtight. The cooling air path is stable and continuous, which effectively improves the battery working temperature environment, improves battery discharge performance, endurance stability and the reliability of long-term continuous operation of the robot.

Detailed Implementation

[0026] The following is in conjunction with the appendix Figure 1 - Appendix Figure 9 This application will be described in further detail below.

[0027] Example: Please see Figures 1-9 As shown, the present invention provides a technical solution: an intelligent interactive humanoid robot, including a robot cavity 1, a battery pack connection unit 2 is provided on the upper and lower parts of the inner side of the robot cavity 1, a cooling unit 3 is provided on the left and right ends of the outer side of the robot cavity 1, and a middle partition plate 105 is welded to the middle part of the inner side of the robot cavity 1. Each battery pack connection unit 2 includes a drive motor 201 and a lifting plate 203. The upper end of the drive motor 201 is fixedly connected to a drive gear 202. The left front part and the right rear part of the lifting plate 203 are fixedly connected to a first threaded sleeve 204. The first threaded sleeve 204 is threadedly engaged with a threaded screw 205. The bottom of the threaded screw 205 is fixedly provided with a driven gear 206. The driven gear 206 meshes with the corresponding drive gear 202. By driving the gear and screw through the drive motor 201, the lifting plate 203 can be stably raised and lowered with high transmission accuracy and good self-locking performance, avoiding loosening or slippage during the raising and lowering process, and improving the docking reliability of the battery pack group 211. The upper part of the lifting plate 203 is equipped with a battery pack 211. The upper rear side of the battery pack 211 is provided with a battery pack electrode protrusion 212. The upper part of the battery pack 211 is provided with a battery pack access plate 209. The battery pack access plate 209 is fixed to the top of the inner side of the robot cavity 1 and the bottom of the middle partition 105 respectively. The bottom rear side of the battery pack access plate 209 is provided with an access slot 214. After the battery pack electrode protrusion 212 moves upward, it inserts and docks with the corresponding access slot 214, realizing automatic plug-in power connection between the battery pack 211 and the battery pack access plate 209. The contact is stable and the conductivity is reliable, and the power supply circuit can be established quickly. The robot cavity 1 has battery inlet and outlet slots 102 on the upper and lower front sides. The upper part of each battery inlet and outlet slot 102 has a raised anti-collision groove 103. The battery pack 211 and the battery pack electrode protrusion 212 on its upper part are pushed into the robot cavity 1 after being inserted into the corresponding battery inlet and outlet slot 102 and the middle partition 105, respectively. This facilitates the quick installation and removal of the battery pack 211, simplifying the disassembly and assembly process. At the same time, the raised anti-collision groove 103 can protect the battery pack electrode protrusion 212 from being damaged by collision. Horizontal bevel gears 215 are fixedly connected to the rotating shaft of the drive motor 201. Inside the robot cavity 1, at the bottom of the lifting plate 203, bidirectional screws 217 are rotatably mounted. Vertical bevel gears 216 are fixedly connected to the middle of each upper bidirectional screw 217, and each vertical bevel gear 216 meshes with a corresponding horizontal bevel gear 215. Second threaded sleeves 219 are threaded to the left and right ends of the bidirectional screws 217, and clamping rubber plates 220 are fixedly connected to the upper ends of the second threaded sleeves 219. The drive motor 201... 01 Synchronously drive the horizontal bevel gear 215 to rotate, which in turn drives the vertical bevel gear 216 and the bidirectional screw 217 to rotate. As the battery pack 211 rises, the battery pack electrode protrusions 212 are inserted into the corresponding access slots 214. The clamping rubber plate 220 clamps the left and right sections of the battery pack 211, so that the battery pack 211 is in a stable working state inside the robot cavity 1. This prevents the battery pack 211 from shaking when the robot cavity 1 moves, which would cause the battery pack electrode protrusions 212 to be unstable in their connection with the access slots 214.

[0028] Sleeves 207 are welded to the rear left side and the front right side of the lifting plate 203. Guide sliding columns 208 are provided on the inner side of the sleeves 207, so that the lifting plate 203 can be lifted vertically along the guide sliding columns 208 without tilting or jamming, ensuring that the battery pack electrode protrusion 212 is precisely connected to the inlet slot 214. Each threaded screw 205 has a first bearing seat 213 at its bottom. The first bearing seat 213 is fixedly connected to the bottom of the corresponding robot cavity 1 and the upper part of the middle partition 105, respectively, to reduce the rotational friction resistance of the threaded screw 205, improve the transmission efficiency, and extend the service life of the drive motor 201 and the screw assembly. The left and right ends of the bidirectional screw 217 are fixedly connected to the second bearing housing 218, which increases the rotational stability of the second bearing housing 218.

[0029] The battery pack access plate 209 has rod mounting slots 210 on the left and right sides and front and rear sides. The bottom ends of the threaded screw 205 and the guide sliding column 208 are fixedly connected to the bottom of the corresponding robot cavity 1 and the upper part of the middle partition 105, respectively. The upper ends of the threaded screw 205 and the guide sliding column 208 are fixedly connected to the inner side of the corresponding rod mounting slot 210, so that the upper and lower ends of the threaded screw 205 and the guide sliding column 208 are fixed, resulting in high structural rigidity, more stable operation, and avoidance of shaking during lifting. The upper front and middle sides of the robot cavity 1 are provided with insertion slots 104. After the battery pack access plate 209 is inserted into the insertion slot 104, it is fixed to the robot cavity 1 by bolts. This facilitates the positioning, installation, disassembly and maintenance of the battery pack access plate 209. It is firmly fixed and not easy to loosen or shift.

[0030] A rear cover plate 101 is fixedly connected to the rear side of the robot cavity 1 by bolts; Motor mounting slots 106 are provided in the middle of the bottom side of the robot cavity 1 and the middle of the upper side of the middle partition 105. The drive motors 201 are fixedly connected to the inner side of the corresponding motor mounting slots 106, so that the drive motors 201 are installed and positioned accurately, firmly and reliably, reducing operating vibration and ensuring stable meshing between the drive gear 202 and the driven gear 206.

[0031] The upper front side of the battery pack 211 is fixedly connected with a first sealing plate 4 by bolts. After the first sealing plate 4 rises with the battery pack 211, it seals and covers the raised anti-collision groove 103. After rising to the position, it automatically closes the raised anti-collision groove 103, which plays the role of preventing dust, water, and foreign objects from entering, and protecting the internal electrode structure. A second sealing plate 5 is welded to the front side of the lifting plate 203. After the second sealing plate 5 rises with the lifting plate 203, it seals and covers the battery inlet / outlet slot 102. It moves synchronously with the lifting plate 203 and automatically seals the battery inlet / outlet slot 102, thereby improving the overall sealing and protection level of the robot cavity 1.

[0032] The upper left and right sides of the battery pack assembly 211 are both glued and fixed with first rubber pads 6. After the first rubber pads 6 rise with the battery pack assembly 211, they abut against the bottom of the battery pack access plate 209, which plays a buffering and stopping role, avoiding rigid collision between the battery pack assembly 211 and the battery pack access plate 209, and improving the contact sealing and insulation. A protective plate 7 is fixedly installed on the upper part of the drive gear 202. A clearance groove 701 is provided at each of the four corners of the protective plate 7. Several second rubber pads 8 are equidistantly bonded to the upper part of the protective plate 7. After the lifting plate 203 is lowered, it is mounted on the upper part of the corresponding second rubber pad 8. This can shield and protect the gear transmission structure below, preventing dust and debris from entering. At the same time, the second rubber pad 8 provides soft landing support for the lifting plate 203, reducing impact and noise.

[0033] The cooling unit 3 includes a miniature air pump 301 fixedly connected to the middle of the left and right sides of the robot cavity 1. The cooling unit 3 also includes eight diffuser connecting sleeves 302 set at the four corners of the left and right sides of the robot cavity 1. Each diffuser connecting sleeve 302 has a vortex air duct 303 fixedly installed at its outer end. Each vortex air duct 303 has an air inlet connecting pipe 304 connected to its outer side. The air inlet connecting pipe 304 is connected to the miniature air pump 301 on the corresponding side through a connecting head to form a multi-point distributed cooling air path, which can simultaneously and evenly dissipate heat from the upper and lower battery packs 211, quickly reduce the battery operating temperature, and improve battery life and safety.

[0034] The robot cavity 1 has annular insertion slots 107 at the four corners on the left and right sides, and a retaining ring 305 is provided on the inner side of the diffusion connecting sleeve 302. The retaining ring 305 is respectively engaged and connected to the inner side of the corresponding annular insertion slot 107, so as to realize the quick positioning and clamping of the diffusion connecting sleeve 302, which is convenient for assembly and the connection is tight and not easy to fall off. The outer side of the diffusion connecting sleeve 302 is welded with side ears 306, which are fixedly connected to the robot cavity 1 by bolts to further reinforce the diffusion connecting sleeve 302, ensuring that the cooling pipe does not loosen or leak air under operating vibration, and that the cooling effect is stable and reliable.

[0035] The implementation principle of this application embodiment is as follows: During installation, first open the rear cover plate 101 on the rear side of the robot cavity 1, insert the battery pack access plate 209 into the insertion slot 104 on the front side of the robot cavity 1, and fix it with bolts after it enters the robot cavity 1. Then, install the drive motor 201, drive gear 202, lifting plate 203, threaded screw 205 and guide sliding column 208 in the corresponding installation positions inside the robot cavity 1 in sequence, so that the first threaded sleeve 204 and the threaded screw 205 are engaged, and the sleeve 207 and the guide sliding column 208 are sleeved to ensure that the lifting structure is stable and smooth. At the same time, the diffusion connecting sleeve 302 of the cooling unit 3 is inserted into the annular insertion groove 107 on the side wall of the robot cavity 1 through the retaining ring 305, and is fixed to the robot cavity 1 with bolts using the side lug 306 to complete the overall assembly. During use, the battery packs 211 on the upper and lower sides of the robot cavity 1 operate in an independent lifting and alternating power supply mode. First, the upper battery pack 211 rises smoothly under the transmission of the drive motor 201, drive gear 202, driven gear 206 and threaded screw 205, so that the battery pack electrode protrusions 212 are inserted into the access slots 214 at the bottom of the battery pack access plate 209 to achieve stable power supply. When the upper battery pack 211 is depleted, it automatically descends and cuts off the power. The lower battery pack 211 then rises to complete the docking and power supply. The two battery packs 211 switch seamlessly, effectively extending the battery life of the humanoid robot. The drive motor 201 synchronously drives the horizontal bevel gear 215 to rotate, which drives the vertical bevel gear 216 and the bidirectional screw 217 to rotate. When the battery pack 211 rises, the battery pack electrode protrusions 212 are inserted into the corresponding access slots 214 respectively, and the clamping rubber plate 220 clamps the left and right sections of the battery pack 211. When the battery packs 211 in the upper and lower parts of the robot cavity 1 are both depleted, the two battery packs 211 can be quickly disassembled and replaced directly through the battery inlet / outlet slot 102, which significantly improves the convenience and efficiency of battery replacement. When charging at night, there is no need to disassemble the upper and lower battery packs 211; charging can be completed directly by plugging in the external plug, making it more flexible to use. After the battery pack 211 is raised into position, the first sealing plate 4 on the upper front side of the battery pack 211 simultaneously seals and covers the raised anti-collision groove 103, and the second sealing plate 5 on the front side of the lifting plate 203 simultaneously seals and covers the battery inlet and outlet groove 102, forming a complete dustproof, waterproof and anti-collision protection structure. The first rubber pad 6 on the upper left and right sides of the battery pack 211 rises with the battery pack 211 and abuts against the bottom of the battery pack access plate 209, which plays a buffering and stopping role. When the lifting plate 203 descends, it is mounted on the second rubber pad 8 on the upper part of the protective plate 7 to reduce impact and wear and protect the internal transmission structure. Meanwhile, the cooling unit 3 continuously dissipates heat for the battery pack 211. The micro air pump 301 delivers airflow to the vortex air duct 303 through the air inlet connection pipe 304, and then diffuses the cold air evenly into the robot cavity 1 through the diffusion connection sleeve 302. The hot air is directly discharged to the outside of the humanoid robot, quickly removing the heat generated by the battery pack 211 during operation, avoiding the impact of high temperature on battery performance and service life, and ensuring the long-term stable operation of the robot.
