Description

Technical Field

[0001] This utility model relates to the field of intelligent toy technology, and in particular to a doll breathing simulator. Background Technology

[0002] In the process of infants' and toddlers' development, dolls, as common companion toys, play an important role in soothing emotions and providing a sense of security. However, existing dolls are usually statically designed, with relatively simple appearance and functions, lacking biomimicry and interactivity, and unable to realistically simulate human physiological characteristics or behaviors, such as breathing and heartbeat. This static characteristic limits the role of dolls in psychological comfort, especially at night or when infants and toddlers are anxious, making it difficult to effectively provide a companion-like experience. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a doll breathing simulator, which can enhance the doll's biomimetic effect and improve its calming effect.

[0004] The doll breathing simulator according to a first aspect of the present invention includes:

[0005] The outer casing unit includes a first casing and a second casing, which together form an accommodating space. The first casing is provided with a telescopic channel leading to the outside.

[0006] A simulated breathing unit includes a power component and a telescopic component. The power component is disposed within the receiving space, and the telescopic component is slidably disposed in the telescopic channel and is capable of reciprocating along the telescopic channel to simulate breathing movements.

[0007] The control unit includes a controller electrically connected to the power assembly for controlling the start or stop of the power assembly.

[0008] The doll breathing simulator according to the embodiments of this utility model has at least the following beneficial effects: by setting up a simulated breathing unit, especially the power component driving the telescopic component to reciprocate in the telescopic channel, it can simulate the rising and falling movements of the human chest or abdomen, achieving breathing movements close to those of a real human body, significantly improving the doll's bionics and interactivity; the device can simulate a regular breathing rhythm, providing infants and young children with a sense of security similar to real-life companionship, especially suitable for scenarios such as falling asleep at night or emotional instability, helping to alleviate infants' and young children's anxiety and enhance psychological comfort; the outer shell unit consists of a first shell and a second shell, enclosing a space to house key components such as the power component, resulting in a compact, safe, and reliable overall structure that does not affect the softness and aesthetics of the doll's appearance; the controller in the control unit is electrically connected to the power component, and can control the start and stop of the breathing simulation function as needed, making it easy to operate and convenient to integrate into an intelligent doll system for remote control or automatic operation.

[0009] According to some embodiments of this utility model, the telescopic assembly includes a first telescopic shell and a second telescopic shell. The first telescopic shell is sleeved on the power assembly and is drively connected to the output shaft of the power assembly. The first telescopic shell is provided with a transmission groove. The output end of the power assembly is constructed as a transmission block, which is embedded in the transmission groove. The second telescopic shell is sleeved on the first telescopic shell. The transmission groove cooperates with the transmission block to convert the circular motion of the power assembly into the reciprocating telescopic motion of the telescopic assembly in the vertical direction. The first telescopic shell and the second telescopic shell perform the reciprocating telescopic motion synchronously. The first telescopic shell and the second telescopic shell achieve synchronous reciprocating motion under the transmission action, ensuring the consistency and stability of the telescopic action, avoiding jamming or deformation problems caused by asynchronous movement, and improving the reliability of the device operation.

[0010] According to some embodiments of this utility model, the power assembly further includes a drive motor, a first reduction gear set, and a second reduction gear set. The first reduction gear set is driven by the output end of the drive motor, and the first reduction gear set is driven by the second reduction gear set. The output end of the second reduction gear set is driven by the transmission block. This multi-stage reduction gear transmission method not only improves the stability of power transmission but also effectively reduces vibration and noise caused by the high-speed operation of the motor, thereby enhancing the overall quietness and comfort of the doll's operation and making it more suitable for infants and young children.

[0011] According to some embodiments of this utility model, the surface of the second telescopic shell is provided with an arc-shaped convex surface, which protrudes away from the receiving space. The design of the arc-shaped convex surface is closer to the natural shape of the human chest or abdomen. When the telescopic component reciprocates, it can more realistically simulate the chest and abdomen rise and fall during human breathing, further enhancing the biomimicry and visual realism of the doll.

[0012] According to some embodiments of this utility model, the telescopic assembly further includes a connecting cover, which is disposed on the surface of the second telescopic shell. The connecting cover has a clearance space corresponding to the position of the arc-shaped convex surface. The surface of the connecting cover has several connecting holes for sewing and fixing the doll breathing simulator inside the doll. The connecting holes on the connecting cover provide a standard interface for sewing and fixing, allowing the doll breathing simulator to be easily and securely embedded and sewn and fixed inside the doll, ensuring that the device is not easily displaced or detached during use, thus improving assembly efficiency and product reliability.

[0013] According to some embodiments of this utility model, the top of the second telescopic shell is provided with a snap-fit ​​groove, which is located outside the arc-shaped convex surface. The bottom of the connecting cover is provided with a buckle, and the connecting cover is installed on the second telescopic shell by the cooperation of the buckle and the snap-fit ​​groove. The use of the buckle and snap-fit ​​groove cooperation method allows the connecting cover to be quickly and securely installed on the second telescopic shell without the need for additional tools or complex fasteners, simplifying the assembly process and improving production efficiency and ease of subsequent maintenance.

[0014] According to some embodiments of this utility model, the second telescopic shell is made of a light-transmitting material, and a light-emitting component is provided on the surface of the first telescopic shell. The light-emitting component is electrically connected to the controller. When the telescopic component is activated, the controller controls the light-emitting component to activate and emit light synchronously. By controlling the light-emitting component and the telescopic component to start and stop synchronously, the light emission effect is coordinated with the simulated breathing movements, such as the soft light changes that simulate the flickering of a heartbeat or the rise and fall of the chest, further enhancing the simulation effect of the doll's vital signs.

[0015] According to some embodiments of this utility model, the control unit further includes a conductive rubber button. The conductive rubber button passes through the shell wall of the first housing. The trigger end of the conductive rubber button normally abuts against the inner wall of the second telescopic shell. The conductive rubber button is electrically connected to the controller and is used to send a trigger signal to the controller. When the user presses the second telescopic shell to move it towards the first telescopic shell, the inner wall of the second telescopic shell triggers the conductive rubber button, and the controller controls the power component to start or stop. The conductive rubber button is directly embedded in the first housing and cooperates with the second telescopic shell, eliminating the need for additional independent physical buttons or sensing devices, saving internal space, and facilitating product miniaturization and compact structural design.

[0016] According to some embodiments of this utility model, the second telescopic shell is provided with a guide post, and the first telescopic shell is provided with a guide hole. The guide post passes through the guide hole to guide the telescopic movement of the second telescopic shell relative to the first telescopic shell. The cooperation between the guide post and the guide hole effectively limits the offset or rotation of the second telescopic shell during the telescopic process, ensuring its smooth movement along a predetermined direction and improving the accuracy and consistency of the breathing simulation action.

[0017] According to some embodiments of this utility model, the control unit further includes a microphone, which is electrically connected to the controller. When the microphone detects a crying sound, the controller activates the power component. By sensing the infant's crying sound through the microphone and triggering simulated breathing movements, the doll can actively respond to the infant's emotional changes, providing immediate bionic companionship and psychological comfort, and enhancing the soothing effect.

[0033] The control unit includes a controller electrically connected to the power component for controlling the start or stop of the power component.

[0034] By incorporating a simulated breathing unit, particularly a power component that drives the telescopic component to reciprocate within the telescopic channel 120, the device can simulate the rising and falling movements of the human chest or abdomen, achieving breathing actions close to those of a real human. This significantly enhances the doll's biomimicry and interactivity. The device can simulate a regular breathing rhythm, providing infants and toddlers with a sense of security similar to real-life companionship. It is especially suitable for scenarios such as falling asleep at night or emotional instability, helping to alleviate infants' anxiety and enhance psychological comfort. The outer shell unit consists of a first shell 100 and a second shell 110, which enclose and form a receiving space to house key components such as the power component.

The controller in the control unit is electrically connected to the power component and can control the start and stop of the breathing simulation function as needed. It is easy to operate and can be easily integrated into a smart doll system for remote control or automatic operation.

[0035] The telescopic assembly includes a first telescopic shell 170 and a second telescopic shell 150. The first telescopic shell 170 is sleeved on the power assembly and is drive-connected to the output shaft of the power assembly. The first telescopic shell 170 is provided with a transmission groove 240. The output end of the power assembly is constructed as a transmission block 230, which is embedded in the transmission groove 240. The second telescopic shell 150 is sleeved on the first telescopic shell 170. The transmission groove 240 and the transmission block 230 cooperate to convert the circular motion of the power assembly into the reciprocating telescopic motion of the telescopic assembly in the vertical direction. The first telescopic shell 170 and the second telescopic shell 150 reciprocate synchronously. The first telescopic shell 170 and the second telescopic shell 150 achieve synchronous reciprocating motion under the transmission action, ensuring the consistency and stability of the telescopic action, avoiding jamming or deformation problems caused by asynchronous movement, and improving the reliability of the device operation.

[0036] The power assembly also includes a drive motor 200, a first reduction gear set 210, and a second reduction gear set 220. The first reduction gear set 210 is connected to the output end of the drive motor 200, and the first reduction gear set 210 is connected to the second reduction gear set 220. The output end of the second reduction gear set 220 is connected to the transmission block 230. This multi-stage reduction gear transmission not only improves the stability of power transmission but also effectively reduces vibration and noise caused by the high-speed operation of the motor, thereby enhancing the overall quietness and comfort of the doll's operation and making it more suitable for infants and young children.

[0037] The surface of the second telescopic shell 150 is provided with an arc-shaped convex surface 250, which protrudes away from the receiving space. The design of the arc-shaped convex surface 250 is closer to the natural shape of the human chest or abdomen. When the telescopic component reciprocates, it can more realistically simulate the chest and abdomen rise and fall during human breathing, further enhancing the biomimicry and visual realism of the doll.

[0038] The telescopic assembly also includes a connecting cover 130, which covers the surface of the second telescopic shell 150. The connecting cover 130 has a clearance space corresponding to the position of the arc-shaped convex surface 250. The surface of the connecting cover 130 has several connecting holes 140 for sewing and fixing the doll breathing simulator inside the doll. The connecting holes 140 on the connecting cover 130 provide a standard interface for sewing and fixing, allowing the doll breathing simulator to be easily and securely embedded and sewn into the doll, ensuring that the device is not easily displaced or detached during use, improving assembly efficiency and product reliability.

[0039] The top of the second telescopic housing 150 is provided with a snap-fit ​​groove 160, which is located outside the arc-shaped convex surface 250. The bottom of the connecting cover 130 is provided with a buckle. The connecting cover 130 is installed on the second telescopic housing 150 by the engagement of the buckle and the snap-fit ​​groove 160. The use of the buckle and the snap-fit ​​groove 160 allows the connecting cover 130 to be quickly and securely installed on the second telescopic housing 150 without the need for additional tools or complex fasteners, simplifying the assembly process and improving production efficiency and ease of maintenance.

[0040] The second telescopic shell 150 is made of a light-transmitting material, and the surface of the first telescopic shell 170 is provided with a light-emitting component. The light-emitting component is electrically connected to the controller. When the telescopic component is activated, the controller controls the light-emitting component to activate and emit light synchronously. By controlling the light-emitting component and the telescopic component to start and stop synchronously, the light-emitting effect is coordinated with the simulated breathing movements, such as the soft light changes that simulate the flickering of a heartbeat or the rise and fall of the chest, further enhancing the simulation effect of the doll's vital signs.

[0041] The control unit also includes a conductive rubber button 180, which is inserted through the wall of the first housing 100. The trigger end of the conductive rubber button 180 normally abuts against the inner wall of the second telescopic housing 150. The conductive rubber button 180 is electrically connected to the controller and is used to send a trigger signal to the controller. When the user presses the second telescopic housing 150 to move it towards the first telescopic housing 170, the inner wall of the second telescopic housing 150 triggers the conductive rubber button 180, and the controller controls the power component to start or stop. The conductive rubber button 180 is directly embedded in the first housing 100 and cooperates with the second telescopic housing 150, eliminating the need for additional physical buttons or sensing devices, saving internal space, and facilitating product miniaturization and compact structural design.

[0042] The second telescopic shell 150 is provided with a guide post, and the first telescopic shell 170 is provided with a guide hole 190. The guide post passes through the guide hole 190 to guide the telescopic movement of the second telescopic shell 150 relative to the first telescopic shell 170. Through the cooperation of the guide post and the guide hole 190, the offset or rotation of the second telescopic shell 150 during the telescopic process is effectively limited, ensuring that it moves smoothly in the predetermined direction, thereby improving the accuracy and consistency of the breathing simulation action.

[0043] The control unit also includes a microphone, which is electrically connected to the controller. When the microphone detects a cry, the controller activates the power unit. By sensing the infant's cry through the microphone and triggering simulated breathing movements, the doll can actively respond to the infant's emotional changes, providing immediate bionic companionship and psychological comfort, and enhancing the soothing effect.

[0044] This invention provides a doll breathing simulator, comprising three main parts: a shell unit, a simulated breathing unit, and a control unit.

[0045] The outer shell unit is used to house the internal components and serves as the basic structure for connection with the doll body. The first shell 100 is provided with a telescopic channel 120 for guiding the movement of the telescopic components; the second shell 110 and the first shell 100 enclose a housing space for installing components such as power components; the first shell 100 and the second shell 110 are detachably connected by means of snaps or screws, which facilitates assembly and maintenance.

[0046] The simulated breathing unit is used to realize biomimetic breathing movements. The power component includes a drive motor 200, a first reduction gear set 210, and a second reduction gear set 220. The output end of the drive motor 200 is sequentially connected to the two-stage reduction gear sets, ultimately driving the transmission block 230 to rotate. The reduction gear sets are used to reduce the speed and increase the torque, ensuring smooth and controllable operation. The telescopic component includes a first telescopic shell 170 and a second telescopic shell 150. The first telescopic shell 170 is sleeved on the output shaft of the power component and has a transmission groove 240, which cooperates with the transmission block 230 of the power component to convert the circular motion into vertical reciprocating motion. The second telescopic shell 150 is sleeved outside the first telescopic shell 170 and extends and retracts synchronously with it. The second telescopic shell 150 is made of a light-transmitting material and has an arc-shaped outward convex surface 250 on its surface, simulating the rise and fall of the human chest and abdomen.

[0047] The first telescopic shell 170 is equipped with a light-emitting component (such as an LED light) that is electrically connected to the controller and emits light synchronously during telescopic movement. The first telescopic shell 170 is also equipped with a guide post, and the second telescopic shell 150 is equipped with a corresponding guide hole 190. The two work together to guide the movement. The top of the second telescopic shell 150 is equipped with a snap-fit ​​groove 160 for engaging with the snap-fit ​​at the bottom of the connecting cover 130. The connecting cover 130 is provided with clearance space to accommodate the arc-shaped convex surface 250 and is provided with multiple connecting holes 140 for easy sewing and fixing inside the doll.

[0048] The control unit is responsible for the overall system control logic. The controller is electrically connected to the power component, light-emitting component, microphone, etc., and controls their start, stop, and operating mode. The conductive rubber button 180 is inserted into the shell wall of the first housing 100. Under normal conditions, the trigger end abuts against the inner wall of the second telescopic shell 150. When the user presses the second telescopic shell 150 to move it, the conductive rubber button 180 is triggered and sends a signal to the controller to control the start and stop of the power component. The microphone is used to detect sound signals in the environment, especially the cries of infants. When a cry is detected, the controller automatically activates the breathing simulation function.

[0049] Assembly process: Install the drive motor 200 inside the first housing 100, and connect the first reduction gear set 210 and the second reduction gear set 220 in sequence; install the transmission block 230 at the output end of the second reduction gear set 220; sleeve the first telescopic housing 170 onto the transmission shaft, so that the transmission block 230 is embedded in its transmission groove 240; install the LED light-emitting component on the first telescopic housing 170; set the guide post on the surface of the first telescopic housing 170, and correspondingly open the guide hole 190 on the second telescopic housing 150; install the second telescopic housing 15... The 0 is fitted onto the first telescopic shell 170 to ensure that both can slide stably along the guide post; a snap-fit ​​groove 160 is provided on the top of the second telescopic shell 150; the buckle at the bottom of the connecting cover 130 is inserted into the snap-fit ​​groove 160 to complete the cover; a conductive rubber button 180 is provided on the first shell 100 and its trigger end contacts the inner side wall of the second telescopic shell 150; a microphone is installed in a suitable position inside the shell and electrically connected to the controller; finally, the entire device is sewn and fixed to the chest area inside the doll through the connecting hole 140 on the connecting cover 130.

[0050] When an infant cries, the microphone detects the crying signal, and the controller activates the power component. The power component drives the transmission block 230 to rotate, which is converted into the vertical reciprocating motion of the first telescopic shell 170 through the transmission groove 240. The second telescopic shell 150 extends and retracts synchronously with the first telescopic shell 170, forming a breathing motion similar to the rise and fall of a human chest. At the same time, the controller controls the light-emitting component to flash synchronously, simulating a heartbeat or soft breathing light. If a parent or infant presses the second telescopic shell 150, the conductive rubber button 180 is triggered, and the controller switches the power component state (start / stop). The doll continues to simulate breathing motions until the set time ends or the stop signal is triggered again.

[0051] When infants wake up crying at night, the doll automatically activates its breathing simulation function, which, combined with soft lighting, creates a sense of security and helps them fall back asleep. During the day, when infants are emotionally unstable, gently pressing the doll's chest will activate the breathing simulation to relieve anxiety. Through the linkage of light and movement, the doll's sense of life is enhanced, increasing the infant's interest and attachment.

[0052] The doll breathing simulator provided by this invention combines a precise mechanical structure with an intelligent control system to achieve a high degree of simulation of human breathing movements, exhibiting excellent biomimicry, safety, and intelligence. Its compact structure, convenient installation, and rich functionality make it particularly suitable for the field of infant comfort dolls. It can also be extended to applications such as rehabilitation assistive devices and emotional interaction robots, possessing broad market prospects and practical promotional value.

[0053] In some embodiments, the doll breathing simulator further incorporates a built-in speaker, which is disposed inside the housing unit (preferably within the first housing 100 or the second housing 110) and electrically connected to the controller. The speaker can be used to play soothing music, white noise, heartbeat sounds, or other voice cues to complement the breathing simulation and enhance the emotional calming effect on infants and young children.

[0054] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
