Description

Technical Field

[0001] This invention relates to the field of intelligent robot technology, specifically to a portable intelligent robot. Background Technology

[0002] Among portable intelligent robots, intelligent companion voice robots have become one of the mainstream portable intelligent robot categories due to their compact and portable body shape and rich intelligent interactive functions. These robots integrate core modules such as speech recognition, speech synthesis, and intelligent interaction algorithms, and can realize functions such as voice dialogue, emotional companionship, information broadcasting, and command response. They can be carried with you to meet users' needs for companionship, interaction, and information inquiry at any time.

[0003] In practical use, current intelligent companion voice robots, in order to ensure portability, have a compact body size and densely packed internal components such as batteries, main control boards, and voice modules. Prolonged voice interaction and high-frequency command responses will cause the battery to continuously discharge under high load. In addition, the limited heat dissipation space of the body makes it easy for heat to accumulate quickly, which can easily lead to abnormal temperature rise of the built-in soft-pack battery. At the same time, it is not easy to quickly achieve safe isolation and risk management after the battery reaches a high temperature. It is impossible to isolate the battery from the core components inside the robot in time to avoid high temperature battery leakage, bulging and damage to key components such as voice modules and main control boards. It is also difficult to prevent heat dissipation from causing the entire robot to malfunction, thus creating safety hazards.

[0004] To address the above problems, a portable intelligent robot is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a portable intelligent robot. By using this invention, the problem in the above-mentioned intelligent companion voice robot is that the internal soft-pack battery is prone to abnormal temperature rise during use. At the same time, it is not easy to quickly achieve safe isolation and risk management after the battery reaches a high temperature. It is impossible to isolate the battery from the core components inside the robot in time to avoid high temperature battery leakage, bulging and damage to key components such as voice module and main control board. It is also difficult to prevent heat dissipation from causing the robot to malfunction and thus creating safety hazards.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A portable intelligent robot includes an intelligent companion robot. The intelligent companion robot has a base fixedly connected to its bottom. Two safety chambers are slidably disposed within the base, each containing an elastic fixing component. Several pressure relief components are located on the top of each elastic fixing component. A positioning component is disposed within the base and engages with the safety chamber. A pouch battery is disposed within each elastic fixing component. Two first contact blocks are disposed opposite each other on one side of the pouch battery. A connecting component is slidably connected within the base and abuts against the first contact blocks. Two first deformation components are slidably disposed within the base and abut against the two pouch batteries respectively. A second deformation component is disposed within each of the two first deformation components. A cutting component is located on one side of each second deformation component. Fire extinguishing components are located on the top of the inner walls of both safety chambers.

[0007] Furthermore, the safety compartment includes a sliding frame slidably connected to the base, an arc-shaped plate fixedly connected to one side of the sliding frame, a through hole through the arc-shaped plate, and slots on the top and bottom of the sliding frame.

[0008] Furthermore, the elastic fixing component includes a movable plate slidably connected within the sliding frame. A plurality of first springs are evenly arranged on one side of the movable plate, and the other end of the plurality of first springs is fixedly connected to one side of the arc-shaped plate. A metal corrugated pipe is fixedly connected to one side of the movable plate, and the other end of the metal corrugated pipe is fixedly connected to one side of the arc-shaped plate. The position of the metal corrugated pipe corresponds to the position of the through hole. Two elastic clamps are fixedly connected to one side of the movable plate.

[0009] Furthermore, the pressure relief assembly includes several microholes extending through the top of the sliding frame, with a breathable membrane fixedly connected inside each microhole.

[0010] Furthermore, the positioning component includes a snap-fit ​​rod slidably connected to the base, the snap-fit ​​rod engaging with a snap-fit ​​groove, a second spring fixedly connected to one end of the snap-fit ​​rod, and the other end of the second spring fixedly connected to the inner wall of the base.

[0011] Furthermore, the connecting assembly includes a slidably connected inclined block within the base, a third spring fixedly connected to one side of the inclined block, and the other end of the third spring fixedly connected to the inner wall of the base. Rolling shafts are rotatably connected to both sides of the inclined block, and the rolling shafts are slidably connected to the inner wall of the base. A first inclined surface is provided on one side of the inclined block, and a plurality of balls are slidably connected within the first inclined surface. A fourth spring is fixedly connected within the inclined block, and a second contact block is fixedly connected to the other end of the fourth spring. The second contact block is slidably connected to the inclined block.

[0012] Furthermore, the first deformation component includes a first shape memory alloy fixedly connected to the base, a U-shaped frame slidably connected to the base, a heat-conducting plate fixedly connected to the U-shaped frame, the other end of the first shape memory alloy fixedly connected to the heat-conducting plate, a plurality of first heat-conducting rods evenly fixedly connected to one side of the heat-conducting plate, the bottom of the plurality of first heat-conducting rods being in contact with the top of the soft-pack battery, and a second inclined surface being provided on both sides of the U-shaped frame, the second inclined surface being in contact with the ball bearing.

[0013] Furthermore, the second deformation component includes a support rod fixedly connected within the U-shaped frame, and a second shape memory alloy is fixedly connected to one side of the support rod.

[0014] Furthermore, the cutting assembly includes a second heat-conducting rod fixedly connected to one side of the second shape memory alloy. The second heat-conducting rod is slidably connected to the U-shaped frame and the heat-conducting plate, and a triangular blade is provided at the top of one end of the second heat-conducting rod.

[0015] Furthermore, the fire extinguishing assembly includes several dry powder bags fixedly connected to the top of the inner wall of the sliding frame. The bottom of the dry powder bags is provided with a cutting strip, and the cutting strip corresponds to the position of the triangular blade.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: Through the cooperation between the first deformation component, the safety compartment, the positioning component, and the connecting component, when the temperature of the soft-pack battery reaches the preset threshold, the safety compartment can be unlocked and slid out simultaneously, the battery can be returned to the compartment limit, the battery can be sealed and isolated, and the power failure alarm can be triggered simultaneously. This can quickly achieve physical isolation between the battery and the core components, block the spread of heat and leakage, avoid risks from the source, and improve the safety of the robot in multiple scenarios. Through the cooperation between the second deformation component, the cutting component, and the fire extinguishing component, when the battery temperature continues to rise to the high temperature threshold, the dry powder pack can be precisely cut open and the dry powder can be released to fully cover the battery surface, blocking oxygen contact to suppress the spread of thermal runaway. Combined with sealing and pressure relief protection, multiple closed loops are formed to avoid open flame and explosion hazards and ensure safe use. By setting up dual soft-pack batteries, dual independent safety compartments, and matching protective components, redundant power supply can be achieved. When a single battery malfunctions and triggers the protection, the other battery can continue to provide stable power supply, preventing the robot from suddenly stopping. Moreover, the independent protection does not interfere with each other, reducing the risk of fault propagation and greatly improving the robot's power supply stability and reliability. The flexible fixing components can be used to clamp and fix the soft-pack battery, effectively buffering the vibration and impact during the robot's portable movement, preventing the battery from shifting and being damaged by bumps. At the same time, it also takes into account the need for easy disassembly and assembly, making it convenient for later battery replacement and maintenance. It is suitable for mobile use in multiple scenarios, including home and outdoor, and extends the life of the battery and the robot. The pressure relief components allow for the timely release of gas generated by the battery within the safety compartment, balancing the internal pressure to prevent explosion. The breathable membrane blocks dust and impurities and prevents leakage. The high-temperature resistant base resists the high temperatures of thermal runaway, preventing internal structural deformation and avoiding the risk of secondary pressure accumulation.

[0019] 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.

[0020] To address the issue that the internal soft-pack battery of the intelligent companion voice robot is prone to abnormal temperature rise during use, and that it is difficult to quickly and safely isolate and manage the risk after the battery reaches a high temperature, it is impossible to isolate the battery from the robot's core internal components in a timely manner to prevent high-temperature battery leakage, bulging, and damage to critical components such as the voice module and main control board. Furthermore, it is difficult to prevent heat dissipation from causing overall robot malfunction and thus creating safety hazards. Figures 1-12 As shown, the following preferred technical solutions are provided: like Figures 1-3As shown, a portable intelligent robot includes an intelligent companion robot 1. The intelligent companion robot 1 can achieve accurate speech recognition and synthesis, supports voice dialogue interaction, emotional companionship, daily information broadcasting, and voice command response. It can be used in multiple scenarios such as home and outdoors, meeting users' needs for intelligent interaction and companionship at any time. The intelligent companion robot 1 has a base 11 fixedly connected to its bottom. The base 11 can support and fix various components. Two safety chambers 2 are relatively slidably arranged inside the base 11. Each safety chamber 2 is provided with an elastic fixing component 3. Several pressure relief components 4 are provided on the top of the elastic fixing component 3. The base 11 is provided with positioning components 5. There are four sets of positioning components 5. Every two sets of positioning components 5 are arranged opposite each other on both sides of the safety chamber 2. The positioning components 5 can accurately position and stabilize the safety chamber 2, limit its sliding stroke, ensure that the safety chamber 2 is in the preset working position, and avoid displacement. The positioning components 5 are engaged with the safety chamber 2.

[0021] The elastic fixing component 3 houses a pouch battery 6, which provides stable power to the electrical components of the intelligent companion robot 1, adapting to the power supply needs of portable scenarios. The elastic fixing component 3 can elastically clamp and fix the pouch battery 6, while buffering vibrations during robot movement to prevent displacement and damage from impacts. It also facilitates the removal and replacement of the pouch battery 6. The pressure relief component 4 is used to promptly release gas generated by the pouch battery 6 within the safety chamber 2, balancing the pressure inside the chamber and preventing explosion. Two first contact blocks 61 are arranged opposite each other on one side of the pouch battery 6, such as... Figure 7 As shown, a connecting component 7 is slidably connected inside the base 11. The connecting component 7 is in contact with the first contact block 61. There are four sets of connecting components 7, with each pair of connecting components 7 in contact with two first contact blocks 61 respectively. The connecting component 7 can cooperate with the first contact blocks 61 to conduct the power of the soft-pack battery 6 to the various power-consuming components of the robot. Two first deformation components 8 are slidably arranged inside the base 11. The two first deformation components 8 are in contact with two soft-pack batteries 6 respectively. The first deformation components 8 can sense the temperature change of the soft-pack battery 6 in real time. When the battery temperature reaches a preset threshold, the shape memory alloy structure inside the first deformation component 8 deforms, triggering subsequent safety protection actions. The base 11 and its internal structure are made of high-temperature resistant materials, which can resist the heat generated when the soft-pack battery 6 experiences high-temperature thermal runaway, and prevent the internal structure of the base 11 from being damaged due to high-temperature deformation. At the same time, it provides high-temperature resistant protection for the stable operation of components such as the safety chamber 2 and the positioning component 5, ensuring that various safety protection actions are carried out smoothly.

[0022] When the intelligent companion robot 1 is in use, when the temperature of the pouch battery 6 reaches a preset threshold, the shape memory alloy structure inside the first deformation component 8 deforms, causing the safety chamber 2 to overcome the resistance of the positioning component 5 and slide out of the intelligent companion robot 1 a certain distance. Then, the moving structure of the first deformation component 8 fits against one side of the safety chamber 2, sealing the safety chamber 2. Simultaneously, during the process of fitting against the safety chamber 2, the moving structure of the first deformation component 8 pushes the pouch battery 6, allowing it to fully enter the safety chamber 2 and simultaneously compressing the elastic structure of the elastic fixing component 3. This allows the pouch battery 6 to be stably confined within the sealed safety chamber 2 under the clamping action of the elastic fixing component 3, thus achieving the connection between the pouch battery 6 and the intelligent companion robot. The physical isolation of the internal electrical components of the robot 1 blocks heat conduction and leakage diffusion. Compared with existing technologies that lack a linkage protection structure to simultaneously complete the return to the compartment limit, sealing isolation and safe removal after the battery reaches a high temperature, the robot 1 usually provides a single warning or simple heat insulation, which cannot quickly stop the spread of risks and is prone to displacement and collision of the soft-pack battery 6. Through the cooperation of the first deformation component 8, the safety compartment 2 and the elastic fixing component 3, a safety protection closed loop can be completed in the early stage of abnormality of the soft-pack battery 6. This effectively avoids thermal runaway of the soft-pack battery 6 from damaging the voice interaction, main control and other core components of the intelligent companion robot 1. It avoids safety hazards such as open flame and compartment explosion from the source, and greatly improves the safety and service life of the intelligent companion robot 1 for portable use in multiple scenarios such as home and outdoors.

[0023] During the movement of the first deformation component 8, the connecting components 7 on both sides are moved synchronously, causing the connecting components 7 to unstick with the corresponding first contact block 61 and be squeezed into the intelligent companion robot 1. After the connecting components 7 unstick with the corresponding first contact block 61, the alarm inside the intelligent companion robot 1 sounds an alarm to remind the user. The alarm is existing technology and is not shown in the figure. At the same time, by setting two soft-pack batteries 6 opposite to each other, redundant power supply can be achieved. This ensures that if one soft-pack battery 6 experiences abnormal temperature, triggers safety protection actions, or malfunctions, the other soft-pack battery 6 can continue to provide stable power to the voice interaction, alarm, and other power-consuming components of the intelligent companion robot 1, avoiding sudden shutdown of the robot. The two soft-pack batteries 6 are placed independently in two safety compartments 2, each with corresponding elastic fixing components 3 and the first deformation component 8 to achieve independent safety protection without interference. This effectively reduces the risk of safety hazards and power outages caused by a single battery failure, further improving the power supply stability and reliability of the intelligent companion robot 1.

[0024] Each of the two first deformation components 8 is equipped with a second deformation component 9. A cutting component 10 is provided on one side of the second deformation component 9. The second deformation component 9 can sense the temperature change of the pouch battery 6 in real time. When the temperature of the pouch battery 6 reaches the preset high temperature threshold, the shape memory alloy structure inside the second deformation component 9 deforms, which drives the cutting component 10 to move. Fire extinguishing components 20 are provided on the top of the inner wall of each of the two safety chambers 2. The fire extinguishing components 20 are used to store dry powder fire extinguishing medium. After being cut by the cutting component 10, the dry powder is released and covers the surface of the pouch battery 6, blocking the battery from contacting oxygen to suppress thermal runaway and avoid safety risks such as open flame and chamber explosion.

[0025] When the temperature of the pouch battery 6 continues to rise and reaches the preset high-temperature threshold, the shape memory alloy structure inside the second deformation component 9 deforms, driving the cutting component 10 to slide within the first deformation component 8, cutting open the bottom of the fire extinguishing component 20. This allows the dry powder extinguishing medium inside the fire extinguishing component 20 to fall onto the surface of the pouch battery 6, covering the surface with the dry powder extinguishing medium. This quickly blocks the contact between the pouch battery 6 and oxygen, effectively inhibiting the further spread of thermal runaway of the pouch battery 6, preventing the generation of open flames and the leakage and spread of electrolyte. Compared to existing technologies, this method largely lacks a high-temperature thermal runaway stage for the pouch battery 6. The proactive fire suppression mechanism, relying solely on isolation or early warning methods, cannot quickly contain thermal runaway, which could easily lead to damage to the entire intelligent companion robot 1 or even endanger the user's personal safety. Through the linkage of the second deformation component 9 and the cutting component 10, it can achieve rapid triggering and precise fire suppression in the critical state of thermal runaway. Combined with the sealed isolation of the safety chamber 2 and the pressure stabilization protection of the pressure relief component 4, it forms a multi-layered safety closed loop, avoiding serious safety hazards such as the explosion of the soft-pack battery 6 and the leakage of open flames, further improving the safety and reliability of the intelligent companion robot 1 in portable use in various scenarios such as home and outdoors.

[0026] like Figures 2-5 , Figure 7 , Figure 10 and Figure 11 As shown, the safety compartment 2 includes a sliding frame 21 slidably connected to the base 11. A limiting groove is provided in the base 11, and the sliding frame 21 is slidably connected to the limiting groove, which can limit the movement of the sliding frame 21 and prevent the sliding frame 21 from sliding out of the base 11. An arc plate 22 is fixedly connected to one side of the sliding frame 21. The arc plate 22 is fixedly connected to the sliding frame 21 by a screw. At the same time, the arc plate 22 and the sliding frame 21 fit tightly together, which can achieve a seal on one side of the sliding frame 21, preventing the soft-pack battery 6 in the safety compartment 2 from leaking liquid and the generated gas from leaking from the joint between the two, while enhancing the structural stability of the safety compartment 2. The arc plate 22 has a through hole 23, and the top and bottom of the sliding frame 21 are provided with slots 24.

[0027] like Figure 4 , Figure 7 and Figure 10 As shown, the elastic fixing component 3 includes a movable plate 31 slidably connected within the sliding frame 21. Several first springs 32 are evenly arranged on one side of the movable plate 31, and the other end of the several first springs 32 is fixedly connected to one side of the arc plate 22. A metal bellows 33 is fixedly connected to one side of the movable plate 31, and the other end of the metal bellows 33 is fixedly connected to one side of the arc plate 22. The position of the metal bellows 33 corresponds to that of the through hole 23. The metal bellows 33 is made of stainless steel heat-resistant material and has excellent heat resistance and insulation performance. Two elastic clamps 34 are fixedly connected to one side of the movable plate 31. Both elastic clamps 34 are connected to the movable plate 31 by screws for easy subsequent disassembly and assembly. The elastic structure of the above-mentioned elastic fixing component 3 is the first spring 32.

[0028] like Figure 7 , Figure 10 and Figure 11 As shown, the pressure relief component 4 includes several micro-holes 41 that penetrate the top of the sliding frame 21. The micro-holes 41 can promptly discharge the gas generated by the soft-pack battery 6 inside the safety chamber 2, balancing the air pressure inside the chamber. A breathable membrane 42 is fixedly connected inside the micro-holes 41. The breathable membrane 42 allows the gas inside the safety chamber 2 to be discharged through the micro-holes 41, while blocking external dust and impurities from entering the safety chamber 2, preventing the soft-pack battery 6 from leaking out. The breathable membrane 42 is made of polytetrafluoroethylene waterproof and breathable material, which has excellent waterproof, breathable and heat-resistant properties, adapting to the pressure relief protection requirements of the soft-pack battery 6 in high-temperature scenarios, and is not easily aged or damaged. The surface of the breathable membrane 42 is smooth and has the characteristic of resisting dry powder adhesion. At the same time, the residual gas generated by the thermal runaway of the soft-pack battery 6 can be quickly discharged from the protective sealing cavity through the breathable membrane 42 and the micro-holes 41. The exhaust efficiency can match the gas generation rate inside the chamber in real time, ensuring that the pressure inside the safety chamber 2 is always within the safe threshold, fundamentally avoiding the secondary pressure accumulation caused by gas retention after dry powder coverage, and eliminating the risk of secondary chamber explosion.

[0029] like Figure 4 As shown, the positioning component 5 includes a locking rod 51 slidably connected to the base 11. The locking rod 51 engages with the slot 24. One end of the locking rod 51 is arc-shaped, matching the shape of the slot 24, which enables the locking rod 51 and the slot 24 to achieve precise and stable engagement. At the same time, when the safety chamber 2 slides under the driving force of the first deformation component 8, the friction between the two is reduced, making it easy for the locking rod 51 to smoothly disengage from the slot 24 without hindering the sliding stroke of the safety chamber 2. One end of the locking rod 51 is fixedly connected to a second spring 52, and the other end of the second spring 52 is fixedly connected to the inner wall of the base 11. The elastic force of the first spring 32 is greater than that of the second spring 52, which can ensure that the safety chamber 2 can overcome the resistance of the second spring 52 and slide out smoothly without affecting the stable execution of positioning and unlocking.

[0030] like Figure 8 and Figure 9 As shown, the connecting assembly 7 includes a slidably connected inclined block 71 within the base 11. A third spring 72 is fixedly connected to one side of the inclined block 71, and the other end of the third spring 72 is fixedly connected to the inner wall of the base 11. Rolling shafts 73 are rotatably connected to both sides of the inclined block 71, and the rolling shafts 73 are rotatably connected to the inner wall of the base 11. A first inclined surface 74 is provided on one side of the inclined block 71, and a plurality of ball bearings 75 are rotatably connected within the first inclined surface 74. A fourth spring 76 is fixedly connected within the inclined block 71, and the other end of the fourth spring 76 is fixedly connected to a third spring 75. The second contact block 77 is slidably connected to the inclined block 71. When the second contact block 77 is not in contact with the first contact block 61, the elastic force of the fourth spring 76 can prevent the second contact block 77 from sliding out of the inclined block 71. Both the second contact block 77 and the first contact block 61 are provided with arc surfaces, which can reduce the friction loss when the two are in contact to conduct electricity and when they are separated, making it easy for the two to quickly and accurately fit together and smoothly separate. At the same time, it avoids scratching the surface of the contact block with the edge, ensures the conductivity stability, and facilitates the alignment and adaptation during installation.

[0031] like Figures 5-8 , Figure 11 and Figure 12 As shown, the first deformation component 8 includes a first shape memory alloy 81 fixedly connected to the base 11. A U-shaped frame 82 is slidably connected to the base 11. A heat-conducting plate 83 is fixedly connected to the U-shaped frame 82. The other end of the first shape memory alloy 81 is fixedly connected to the heat-conducting plate 83. Several first heat-conducting rods 84 are evenly fixedly connected to one side of the heat-conducting plate 83. The bottom of the several first heat-conducting rods 84 is in contact with the top of the soft-pack battery 6. A second inclined surface 85 is provided on both sides of the U-shaped frame 82. The second inclined surface 85 is in contact with the ball bearing 75. One end of the several first heat-conducting rods 84 is set to be arc-shaped, which can avoid jamming when installing a new soft-pack battery 6. The shape memory alloy structure and the moving structure in the first deformation component 8 are the first shape memory alloy 81 and the U-shaped frame 82, respectively.

[0032] When the intelligent companion robot 1 is in use, when the temperature of the soft-pack battery 6 reaches the preset threshold of the first shape memory alloy 81, the heat of the soft-pack battery 6 is conducted to the first shape memory alloy 81 through the first heat-conducting rod 84 and the heat-conducting plate 83, causing the first shape memory alloy 81 to deform and drive the U-shaped frame 82 to move. The U-shaped frame 82 fits against the soft-pack battery 6 and pushes the moving plate 31 through the soft-pack battery 6, so that the first spring 32 is gradually squeezed until it overcomes the elastic resistance of the second spring 52, causing the locking rod 51 to disengage from the locking slot 24, and then the sliding frame 21 slides out of the intelligent companion robot 1 a certain distance. At the same time, several micro-holes 41 are located outside the intelligent companion robot 1. Then the U-shaped frame 82 fits tightly against one side of the sliding frame 21, so that the sliding frame 21, the U-shaped frame 82, the arc plate 22 and the metal bellows 33 form a protective sealed cavity. The squeezing force on the soft-pack battery 6 during the process will not damage it.

[0033] Simultaneously, as the U-shaped frame 82 fits into the safety compartment 2, it pushes the soft-pack battery 6, allowing it to fully enter the sliding frame 21. This movement also drives the two elastic clamping plates 34 and the moving plate 31, causing the moving plate 31 to slide within the sliding frame 21 and compress the first spring 32. Simultaneously, the metal bellows 33 deforms, ensuring the soft-pack battery 6 is stably confined within the sealed sliding frame 21 under the clamping action of the two elastic clamping plates 34. This achieves physical isolation between the soft-pack battery 6 and the internal electrical components of the intelligent companion robot 1, preventing heat conduction and leakage. Compared to existing technologies that lack a coordinated protection structure to simultaneously complete the return to storage, sealing and isolation, and safe removal of the battery after it reaches high temperatures, this technology typically provides only a single warning or simple heat insulation, which cannot quickly stop the spread of risks and is prone to causing the soft-pack battery 6 to shift or be bumped. This technology can complete a safety protection closed loop in the early stage of the soft-pack battery 6 abnormality, effectively avoiding thermal runaway of the soft-pack battery 6 from damaging the voice interaction, main control and other core components of the smart companion robot 1. It avoids safety hazards such as open flame and explosion from the source, and greatly improves the safety and service life of the smart companion robot 1 for portable use in multiple scenarios such as home and outdoors.

[0034] During the movement of the U-shaped frame 82, the two inclined blocks 71 are squeezed by the cooperation of the second inclined surfaces 85 on both sides and several rolling balls 75, so that the two inclined blocks 71 are pushed into the base 11. At the same time, the second contact block 77 in the two inclined blocks 71 is de-adhered to the corresponding first contact block 61. After the second contact block 77 is de-adhered to the corresponding first contact block 61, the alarm inside the intelligent companion robot 1 sounds an alarm, thereby reminding the user. The alarm is existing technology and is not shown in the figure.

[0035] To address the technical problem of batteries spontaneously combusting and being difficult to extinguish, such as... Figure 3 , Figure 5 , Figure 6 and Figures 10-12 As shown, the following preferred technical solutions are provided: like Figure 6 and Figure 10 As shown, the second deformation component 9 includes a support rod 91 fixedly connected to the U-shaped frame 82. A second shape memory alloy 92 is fixedly connected to one side of the support rod 91. The temperature threshold of the second shape memory alloy 92 is greater than that of the first shape memory alloy 81, which enables graded triggering of safety protection actions. This ensures that the first shape memory alloy 81 first triggers primary protection such as the sliding out of the safety compartment 2 and sealing and isolation. When the temperature of the soft-pack battery 6 continues to rise to a higher threshold, the second shape memory alloy 92 is then triggered to drive the cutting component 10 to perform fire extinguishing actions. This ensures that the two levels of protection are connected in an orderly manner without interfering with each other, thus guaranteeing the pertinence and effectiveness of the protection.

[0036] like Figure 6 , Figure 10 and Figure 12 As shown, the cutting assembly 10 includes a second heat-conducting rod 101 fixedly connected to one side of the second shape memory alloy 92. The second heat-conducting rod 101 is slidably connected to the U-shaped frame 82 and the heat-conducting plate 83 respectively. A triangular blade 102 is provided at the top of one end of the second heat-conducting rod 101. A placement groove is provided on one side of the U-shaped frame 82. When the temperature of the soft-pack battery 6 does not reach the preset high temperature threshold, the triangular blade 102 is in the placement groove. The shape memory alloy structure inside the second deformation assembly 9 is the second shape memory alloy 92.

[0037] like Figure 10 and Figure 11 As shown, the fire extinguishing assembly 20 includes several dry powder bags 201 fixedly connected to the top of the inner wall of the sliding frame 21. The dry powder bags 201 are elongated and filled with dry powder, which can increase the coverage area after the dry powder is released, improve the coverage area of ​​the soft-pack battery 6, block the contact between the soft-pack battery 6 and oxygen, effectively suppress the spread of thermal runaway, and prevent the generation of open flames. The bottom of the dry powder bag 201 is provided with a cutting strip 202, which corresponds to the position of the triangular blade 102. The cutting strip 202 can provide a precise cutting point for the triangular blade 102, reduce the cutting resistance, and enable the triangular blade 102 to quickly and smoothly cut open the dry powder bag 201, so that the dry powder inside can be released in time.

[0038] When the temperature of the pouch battery 6 continues to rise and reaches the preset high-temperature threshold of the second shape memory alloy 92, the heat from the pouch battery 6 is conducted to the second shape memory alloy 92 through the first heat-conducting rod 84, the heat-conducting plate 83, and the second heat-conducting rod 101. This causes the second shape memory alloy 92 to deform, driving several second heat-conducting rods 101 to slide within the U-shaped frame 82 and the heat-conducting plate 83. This causes several triangular blades 102 to cut open the slit strip 202, allowing the dry powder extinguishing medium inside to fall onto the surface of the pouch battery 6. This allows the dry powder extinguishing medium to cover the surface of the pouch battery 6, quickly blocking the contact between the pouch battery 6 and oxygen, effectively inhibiting the further spread of thermal runaway of the pouch battery 6, and preventing... To prevent the generation of open flames and the spread of electrolyte leakage, this technology addresses the lack of an active fire suppression mechanism for the high-temperature thermal runaway stage of the pouch battery 6, which relies on only a single isolation or early warning method. This is insufficient to quickly contain the thermal runaway, which could easily lead to damage to the entire intelligent companion robot 1 or even endanger the user's personal safety. This technology enables rapid triggering and precise fire suppression in the critical state of thermal runaway. Combined with the sealing isolation of the sliding frame 21 and the pressure stabilization protection of the micropores 41 and the breathable membrane 42, it forms a multi-layered safety closed loop, avoiding serious safety hazards such as pouch battery 6 explosion and open flame leakage. This further enhances the safety and reliability of the intelligent companion robot 1 in portable use in various scenarios such as home and outdoor.

[0039] When the temperature of the pouch battery 6 decreases, the first memory alloy 81 and the second memory alloy 92 reach the reset temperature threshold and reset. When replacing the pouch battery 6, the user removes the arc plate 22, pulls out the arc plate 22, the moving plate 31, the first spring 32, the metal bellows 33, the elastic clamp 34, and the pouch battery 6 to be replaced. Then, the user cleans the inside of the sliding frame 21. After that, the user fixes the new pouch battery 6 with the elastic clamp 34, and then uses the external insertion rod to press the moving plate 31 so that the second contact block 77 fits with the corresponding first contact block 61. At the same time, the locking rod 51 engages with the locking slot 24. Then, the arc plate 22 is reconnected to the sliding frame 21 with the screw, thus completing the replacement of the new pouch battery 6.
