Technical Field

[0001] This invention relates to the field of artificial intelligence, and in particular to a robot that combines intimate interaction functions with a pull-resistant arm structure. Background Technology

[0002] With the rapid development of artificial intelligence technology, family companion robots have gradually become important companions in the lives of children, the elderly, and women living alone, significantly improving their quality of life. However, current companion robots on the market have obvious functional limitations: on the one hand, interaction is limited to voice and vision, and the robots themselves lack intimate physical contact to meet users' emotional needs, failing to meet the growing consumer demand for warm and interactive experiences; on the other hand, the robot arms mostly adopt the design schemes of industrial robotic arms or general service robots, and their joint structures and drive systems are not optimized for home use, especially for children's interactive behavior. Children may pull or twist the arms out of curiosity during play, causing damage, and there is currently a lack of integrated solutions that simultaneously consider pull resistance and functional practicality. Therefore, there is an urgent need for a new type of robot that can provide a physical interactive experience and has a durable arm structure to solve the problems existing in the current technology.

[0036] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] As shown in Figures 1-3, this embodiment of the invention provides a robot, including a head and an arm. The head consists of a shell 3 and an interactive part, wherein the interactive part consists of a kneading component 1 and a feedback component. The kneading component 1 is connected to the shell 3, and the shell 3 is fitted onto the robot's head. The arm consists of a skeleton component and a drive component. The skeleton component has a first bone 5, a second bone 6, and a composite joint 4. The first bone 5 and the second bone 6 are movably connected through the composite joint 4. The drive component has a shaft flange, one end of which is connected to the robot's body, and the other end is poweredly connected to the first bone 5.

[0038] Compared with existing technologies, this invention includes a kneading component and a feedback component. While the user relaxes through the kneading motion, the feedback component analyzes the user's kneading movements and provides appropriate interactive feedback, thereby improving the user experience. Simultaneously, the composite joint 1 provides excellent tensile resistance to prevent damage to the robotic arm.

[0039] Specifically, in this embodiment of the invention, the kneading component 1 includes a flexible structure 11 and a tactile element 12. The tactile element 12 is built into the flexible structure 11 and is signal-connected to the flexible structure 11. The flexible structure 11 has good resilience properties, ensuring the user's kneading experience while also facilitating the tactile element 12 to sense the kneading action and pressure changes of the hand, thus providing a guarantee for subsequent tactile analysis.

[0040] In some embodiments, to further enhance the user experience, preferably, there are two sets of kneading components 1, each corresponding to a position on the robot's ears, acting as the robot's ears. Users can simultaneously knead the robot's ears with both hands during interaction, perfectly aligning with people's habits of affectionate interaction with cute animals or children. This design also facilitates robot handling; the two flexible structures 11 forming the robot's ears provide excellent gripping points, especially suitable for child users. Furthermore, when the robot tipes over, the flexible structures 11 act as a good buffer, preventing damage. Additionally, from an aesthetic perspective, the protrusion of the robot's ears is reasonable and does not cause visual discomfort.

[0041] Furthermore, in this embodiment of the invention, the flexible structure 11 is preferably pear-shaped, because the pear shape, which is smaller at the top and larger at the bottom, is more suitable for the palm structure when the human hand is kneading and grasping, and can provide a more comfortable kneading experience, allowing users to relax their mind and body better.

[0042] like Figure 1 As shown, the feedback component of this embodiment of the invention includes an interactive element 2 and a processor, wherein the processor is signal-connected to both the interactive element 2 and the tactile element 12. The processor has a built-in interactive algorithm for analyzing the kneading data transmitted from the tactile element 12 and simultaneously transmitting interactive commands to the interactive element 2 based on the data. The interactive element 2 can be a sensor light strip fitted around the robot's neck or a smart bell mounted on the robot's neck.

[0043] Furthermore, in this embodiment of the invention, the shell 3 is helmet-shaped to facilitate its placement on the robot's head. The lower edge of the shell 3 extends downwards, covering the robot's neck while folding outwards. Specifically, to ensure the robot's head can move freely, a gap is left between the head and torso. The downward extension and outward folding design of the shell 3 not only covers this gap for aesthetic purposes but also prevents fingers from being pinched during head movement. Simultaneously, the outward folding does not impede the robot's head movement.

[0044] Furthermore, the surface of the housing 3 in this embodiment of the invention is preferably covered with a skin-friendly layer to improve the user experience.

[0045] Furthermore, such as Figure 3 As shown, the composite joint 4 of this embodiment includes: a joint assembly 41, a metal mesh layer 43, and a silicone damping layer 44. Specifically, the joint assembly connects the first bone 5 and the second bone 6. The silicone damping layer 44 wraps around the joint assembly 41, and the metal mesh layer 43 wraps around the outside of the silicone damping layer 44. Preferably, carbon fiber reinforcing ribs may be pre-embedded in the metal mesh layer 43 to further enhance strength. Compared with the prior art, the first bone 5 and the second bone 6 of this embodiment are connected by the composite joint 4. The composite joint 4 has high strength, and when the second bone 5 is pulled, the composite joint 4 can play a good anti-pull role to avoid damage to the robot arm. Specifically, the silicone damping layer 44 has a good buffering and energy absorption effect, and can play a good protective role when the arm is pulled. The metal mesh layer 43 has good elasticity and toughness, and wrapping around the outside of the silicone damping layer 44 can further enhance the connection strength between the first bone 5 and the second bone 6.

[0046] Furthermore, such as Figure 3As shown, the joint assembly 41 of this embodiment includes: a first joint 411 and a second joint 412, wherein the first joint 411 is connected to the first bone 6; the second joint 412 is connected to the second bone 6; and the first joint 411 and the second joint 412 are magnetically connected. When the external force is too large, exceeding the magnetic force between the first joint 411 and the second joint 412, the first joint 411 and the second joint 412 automatically disconnect, preventing the external force pulling the second bone 6 from being transmitted to the connection between the first bone 5 and the shaft flange, effectively protecting the relatively fragile and vulnerable drive assembly. Simultaneously, when the external force disappears, the first joint 411 and the second joint 412 can also reconnect under the action of the magnetic force. Preferably, in some embodiments, an electromagnetic coil 42, an electromagnetic brake, and a torque sensor are provided between the first joint 411 and the second joint 412. Specifically, the first joint 411 and the second joint 412 are connected by the magnetic force generated by the electromagnetic coil 42. When the second bone 6 is subjected to an external force, the torque sensor first obtains the abnormal tensile force value, compares it with a preset safety value, and then controls the electromagnetic coil and the electromagnetic brake based on the comparison result. Typically, three safety ranges are preset: Level 1 abnormal tensile force range is 5-8 N·m, Level 2 abnormal tensile force range is 8-12 N·m, and Level 3 abnormal tensile force range is greater than 12 N·m. When Level 1 response is triggered, the servo motor of the drive component will actively reverse to compensate and offset the external force; when Level 2 response is triggered, the electromagnetic brake will lock the joint; when Level 3 response is triggered, the electromagnetic coil 42 is de-energized, and the first joint 411 and the second joint 412 are mechanically disengaged.

[0047] Furthermore, the drive assembly in this embodiment of the invention also includes a servo motor and a locking structure. The servo motor is fixedly connected to the robot body to provide power, while the shaft flange is detachably connected to the servo motor via the locking structure. Specifically, the locking structure has a switch and a locking latch, wherein the latch is used to fix the shaft flange. To prevent accidental activation of the switch and subsequent arm detachment, two switches are provided, each corresponding to one side of the shaft flange. The locking latch will only disconnect from the shaft flange when both switches are triggered simultaneously. Compared with the prior art, this embodiment of the invention is detachable, facilitating user disassembly and cleaning, and changing the robot's clothing.

[0048] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
