Abstract
Description
Technical Field
[0001] This utility model relates to the field of baby stroller technology, and more specifically, to a multifunctional safety baby stroller. Background Technology
[0002] A stroller is a portable means of transportation specifically designed for infants and toddlers. It primarily provides a safe and comfortable riding space for parents when taking their babies out, while also being easy to push and store. Through its rational structural design, it meets the different needs of infants in lying, sitting, and other positions, and has auxiliary functions such as shock absorption, sunshade, and storage, making it an indispensable tool in modern childcare.
[0003] Strollers are divided into lightweight umbrella strollers, high-view strollers, off-road strollers, retro strollers, and smart strollers. Among them, smart strollers are equipped with electric drive, automatic obstacle avoidance, remote control and other functions. Some of them have temperature control, music playback or health monitoring, and are safer. They are generally equipped with an openable sunshade and the backrest angle can be adjusted.
[0004] While existing smart strollers offer good safety, the opening and closing of the sunshade and the adjustment of the backrest angle all require individual adjustment by the user. They cannot be adjusted in a coordinated manner when needed, and users have to adjust them one by one, which is time-consuming. Therefore, we propose a multi-functional safety stroller. Utility Model Content
[0005] The purpose of this invention is to provide a multifunctional safety stroller to address the aforementioned shortcomings of the prior art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a stroller, the stroller including a frame, and a seat installed on the inner side wall of the frame;
[0007] The backrest is hinged to the end opening of the seat via a hinge rod;
[0008] The sunshade is fixed to the top of the frame at one end and hinged to the top of the frame at the other end via a hinge rod, forming a dome-shaped structure.
[0009] The transmission structure includes a clutch, one end of which is provided with a belt drive assembly A and can be driven by the belt drive assembly A and the hinge rod of the backrest; the other end of which is provided with a belt drive assembly B and can be driven by the belt drive assembly B and the hinge rod of the sunshade.
[0010] The brake disengagement structure controls the opening and closing of the clutch, including a clutch pedal assembly. When the clutch pedal assembly is pressed, the clutch is in a fully disengaged state, and when the clutch pedal assembly is not pressed, the clutch is in a fully engaged state.
[0011] As a further description of the above technical solution: a wheel frame assembly is installed at the bottom of the vehicle frame, and a camera is installed at the fixed end of the inner side wall of the sunshade.
[0012] As a further description of the above technical solution: the outer wall of the stroller is equipped with an adjustment mechanism, the adjustment mechanism includes a housing, and a transmission structure is installed inside the housing.
[0013] As a further description of the above technical solution: the belt drive assembly A and the belt drive assembly B have the same structure, both including two pulleys and a belt body. One of the pulleys of the belt drive assembly A is concentrically mounted on the end of the hinge rod of the backrest, and the other pulley of the belt drive assembly A is concentrically mounted on one end of the clutch power end.
[0014] One of the pulleys of the belt drive assembly B is concentrically mounted at the end of the hinge rod of the sunshade, and the other pulley of the belt drive assembly B is located at the other end of the clutch power end.
[0015] As a further description of the above technical solution: a gear A is concentrically mounted on the other end of the power end of the clutch, and a gear B is meshed with the outer wall of the gear A;
[0016] The backrest leveling direction is opposite to the sunshade opening direction.
[0017] As a further description of the above technical solution: the brake separation structure includes a release bearing concentrically mounted on one end of the clutch power end, a release fork is provided on the outer wall of the release bearing, and a brake cable is connected to the outer wall of the release fork and the clutch pedal assembly is connected through the brake cable.
[0018] The multifunctional safety stroller provided by this utility model, as described above, has the following beneficial effects:
[0019] This invention utilizes a transmission structure to synchronously adjust the backrest angle and the sunshade opening and closing. Since babies typically need sun protection when lying down to rest or sleep, and do not require shade when sitting to observe their surroundings, the transmission structure coordinates the rotation of the backrest with the rotation of the sunshade. This allows the sunshade to automatically unfold when the backrest is reclined and automatically retract when the backrest is adjusted to a sitting position, enabling rapid and synchronous adjustment. Furthermore, a brake separation structure controls the clutch engagement and disengagement. Pressing the clutch pedal assembly to a certain extent fully disengages the clutch, allowing for independent adjustment of the backrest angle and sunshade opening and closing, thus solving the problem of limited functionality in existing intelligent safety strollers.

[0032] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0033] Please see Figures 1-5 The present invention provides a technical solution: including a stroller 1, the stroller 1 including a frame 101, and a seat 103 installed on the inner side wall of the frame 101;
[0034] In another embodiment of the present invention, preferably, a wheel frame assembly 102 is installed at the bottom of the frame 101, and a camera 106 is installed at the fixed end of the inner side wall of the sunshade 105.
[0035] 1. Outing Mode, which is the stroller 1 in motion mode, meaning the electric motor of the configured electric assist drive is in a stable state: powered by an external power source, with existing electrical equipment such as electric motors and electric assist drives connected to the existing high-efficiency electric assist system, pushing the stroller 1 is easier and less strenuous, providing parents with a smooth pushing experience on both flat roads and slightly sloping surfaces.
[0036] Real-time monitoring and intelligent speed control: The existing product's monitoring camera 106 monitors the distance ahead in real time. When an object is detected approaching, if a safe distance value L1 is set in the external intelligent control switch, and the distance is less than the safe distance L1, a signal is transmitted to the external intelligent control switch. The external intelligent control switch controls the configured existing equipment motor to automatically reduce the speed to ensure driving safety. In an emergency, if a safe distance value L2 is set in the external intelligent control switch, and the distance is less than the safe distance L2, the existing equipment motor drives the stroller 1 to automatically move backward a certain distance in the opposite direction to avoid collision accidents.
[0037] 2. Home Mode and Safety Mode: When stroller 1 is stationary, meaning the electric motor is stably off, the stroller 1 is powered by an external power source, and camera 106 monitors the baby, using facial AI technology to accurately observe the baby's condition. If the baby is detected crying, the external smart control switch will automatically turn on the connected music player, playing soft music, while simultaneously controlling the lower motor to gently rock stroller 1 back and forth to soothe the baby.
[0038] Abnormal pushing monitoring and protection: In case of sudden rapid movement of stroller 1, i.e., the electric motor suddenly outputs beyond the set value: an existing product speed sensor can be installed on the outer wall of the motor output rod. If someone attempts to push stroller 1 quickly, i.e. the motor output speed is too fast, it will be transmitted to the external intelligent control switch. The external intelligent control switch will control the motor to reduce the output speed, and stroller 1 will automatically reduce speed. Preferably, an alarm such as a buzzer alarm will be activated simultaneously to issue an alarm signal, reminding parents of the possible abnormal situation and effectively preventing stroller 1 from being accidentally pushed away.
[0039] Visitor tracking and recording: If someone approaches the stroller 1, the camera 106 will automatically track the person's face and record the relevant information in the memory pan-tilt unit of the external smart control switch, so that parents can check it later and ensure the baby's safety.
[0040] 3. Anti-loss mode: Positioning and communication device configuration: Utilizing the BeiDou positioning system and Bluetooth communication technology, small, wearable devices such as wristbands and ankle bracelets are made and placed on the baby. Simultaneously, another Bluetooth receiver module (using existing technology and equipment, details omitted) is installed in a concealed and safe location under the stroller 1 to ensure a stable connection between the two.
[0041] Off-car alarm and tracking: When the distance between the baby and stroller 1 exceeds the safe range and the communication signal is lost, a signal is sent to the external smart control switch. The external smart control switch then activates an alarm, such as a buzzer, to simultaneously sound an alarm. Stroller 1 automatically alarms, alerting parents that the baby may be lost. Simultaneously, relevant location information is fed back to the mobile phone in real time (an app connected to the BeiDou positioning system and Bluetooth communication technology needs to be downloaded; this uses existing technology and will not be elaborated upon). This allows parents to quickly locate the baby, reducing the risk of loss. Parents can obtain real-time status information of stroller 1 via their mobile phones, including the baby's condition and location information. They can also remotely operate stroller 1 to some extent, such as emergency braking, improving the convenience and flexibility of childcare.
[0042] Preferably, a variety of high-precision sensors from existing products are used, such as OpenMV camera sensors for infant status monitoring and frontal environment perception, encoder motor sensors for speed monitoring, and distance sensors for frontal distance detection, to collect various types of data in real time. The data is then preprocessed and analyzed by a microprocessor to provide a data foundation for subsequent intelligent decision-making.
[0043] Preferably, the existing advanced facial AI algorithm is used in the external intelligent control switch system to accurately identify the baby's crying expression and achieve quick and effective soothing operation; at the same time, AI technology is also applied to the intelligent control and optimization of the overall system to improve the collaborative work efficiency of various functional modules.
[0044] Preferably, the existing Beidou positioning system and Bluetooth communication module are integrated to realize the interaction and communication between the baby and the stroller 1. The status data and location information of the stroller 1 are transmitted to the mobile phone in real time through existing wireless communication technologies such as 5G or Wi-Fi, so that parents can remotely monitor and manage it.
[0045] Preferably, an intelligent control unit is designed and developed to precisely control the execution modules such as motor drive, music playback, and alarm based on sensor data and AI analysis results, so as to realize the various functions of stroller 1, such as automatic speed adjustment, automatic soothing, and abnormal alarm.
[0046] Preferably, a mobile app is developed, providing a simple and intuitive interface that allows parents to easily view the status of stroller 1 in real time, receive alarm information, perform remote operations, and manage historical data. Simultaneously, the app enables interaction between parents and stroller 1, enhancing the user experience.
[0047] Preferably, it is also equipped with existing foot-operated brake components;
[0048] The backrest 104 is hinged to the end opening of the seat 103 via a hinge rod;
[0049] The sunshade 105 has one end of its frame fixed to the top of the frame 101, and the other end of its frame is hinged to the top of the frame 101 via a hinge rod. It is a dome-shaped structure. The frame is also covered with a canopy fabric, preferably waterproof and sun-proof Oxford cloth.
[0050] In another embodiment of the present invention, an adjustment mechanism 2 is installed on the outer side wall of the stroller 1. The adjustment mechanism 2 includes a housing 203, and a transmission structure 201 is installed inside the housing 203.
[0051] The transmission structure 201 includes a clutch 2012. One end of the power end of the clutch 2012 is provided with a belt drive assembly A2011 and can be driven by the belt drive assembly A2011 and the hinge rod of the backrest 104. The other end of the power end of the clutch 2012 is provided with a belt drive assembly B2015 and can be driven by the belt drive assembly B2015 and the hinge rod of the sunshade 105.
[0052] In another embodiment of the present invention, belt drive assembly A2011 and belt drive assembly B2015 have the same structure, both including two pulleys and a belt body. One of the pulleys of belt drive assembly A2011 is concentrically mounted on the end of the hinge rod of backrest 104, and the other pulley of belt drive assembly A2011 is concentrically mounted on one end of the power end of clutch 2012.
[0053] One of the pulleys of the belt drive assembly B2015 is concentrically mounted at the end of the hinge rod of the sunshade 105, and the other pulley of the belt drive assembly B2015 is located at the other end of the power end of the clutch 2012.
[0054] In another embodiment of the present invention, a gear A2013 is concentrically mounted on the other end of the power end of the clutch 2012, and a gear B2014 is meshed with the outer wall of the gear A2013.
[0055] The backrest 104 is leveled in the opposite direction to the awning 105.
[0056] The brake separation structure 202 controls the opening and closing of the clutch 2012 and includes a clutch pedal assembly 2024. When the clutch pedal assembly 2024 is pressed, the clutch 2012 is in a fully disengaged state, and when the clutch pedal assembly 2024 is not pressed, the clutch 2012 is in a fully engaged state.
[0057] In another embodiment of the present invention, the brake separation structure 202 includes a release bearing 2021 concentrically mounted on one end of the power end of the clutch 2012. A release fork 2022 is provided on the outer wall of the release bearing 2021. A brake cable 2023 is connected to the outer wall of the release fork 2022 and a clutch pedal assembly 2024 is connected through the brake cable 2023.
[0058] Preferably, the clutch pedal assembly 2024 can be installed at the end of the stroller handle 1 for easy pressing control when pushing. When the clutch pedal assembly 2024 is not pressed, the release fork 2022 does not act on the release bearing 2021, the clutch 2012 is in a fully engaged state, and the backrest 104 and sunshade 105 are adjusted in conjunction. When the clutch pedal assembly 2024 is pressed to a certain extent, the brake cable 2023 pulls the release fork 2022 to push the release bearing 2021, so that the clutch 2012 is in a fully disengaged state. At this time, the angle of the backrest 104 or the opening and closing of the sunshade 105 can be adjusted independently.
[0059] Working principle: This embodiment provides a multi-functional safety stroller 1. In use, this utility model can synchronously adjust the angle of the backrest 104 and the opening and closing of the sunshade 105 through the transmission structure 201. Since in most cases, the baby needs sun protection when lying down to rest and sleep, and does not need to be blocked when the baby is sitting to observe the surrounding environment, the rotational movement of the backrest 104 is coordinated with the rotational movement of the sunshade 105 through the transmission structure 201, so that the sunshade 105 automatically unfolds when the backrest 104 is laid down and automatically closes when the backrest 104 is adjusted to a sitting position. It can be quickly and synchronously adjusted, saving time and simplifying the adjustment steps.
[0060] The backrest 104 is leveled in the opposite direction to the sunshade 105 opening direction. Normally, when the clutch pedal assembly 2024 is not pressed, the release fork 2022 does not act on the release bearing 2021, and the clutch 2012 is in a fully engaged state. At this time, whether you control the opening and closing of the sunshade 105 by hand or adjust the angle of the backrest 104 by hand, both are adjusted in conjunction.
[0061] When the movable end frame of the sunshade 105 is held and pulled to open the sunshade 105, the hinge rod of the sunshade 105 rotates counterclockwise. Through the belt drive assembly B2015, the gear B2014 rotates counterclockwise in sync. Since the outer wall of the gear B2014 is meshed with the gear A2013, the gear A2013 and the clutch 2012, which is in a fully engaged state, rotate clockwise in sync. Through the belt drive assembly A2011, the hinge rod of the backrest 104 rotates clockwise in sync, and the backrest 104 is adjusted to a flat position in sync.
[0062] Preferably, in actual use, a limiting component is also required to limit the maximum rotation angle of the hinge rod of the sunshade 105 and the hinge rod of the backrest 104. At the same time, the transmission ratio needs to be adjusted according to actual needs so that when the sunshade 105 is opened to the maximum state, the backrest 104 is adjusted to the required lying angle, and when the sunshade 105 is closed, the backrest 104 is adjusted to the required sitting angle.
[0063] When it is necessary to open or close the sunshade 105 or adjust the angle of the backrest 104 separately, press the clutch pedal assembly 2024. The clutch 2012 is in a fully disengaged state, that is, the gears A2013 at both ends of the clutch 2012 and the concentric pulleys of the belt drive assembly A2011 are separated, and the angle of the backrest 104 and the opening and closing of the sunshade 105 can be adjusted separately (the camera 106, clutch 2012 and brake separation structure 202 all use existing products and the camera 106 is connected to an external smart switch and an external power source).
[0064] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
