Description

Smart trolley

The present invention relates to a smart trolley, and more particularly to a trolley that can be combined with a mobile application to achieve safe and interesting smart operation.

Usually, families with babies and young children will have a baby stroller for them to ride in. Adults can reduce the burden of holding or carrying the baby, and at the same time, the baby can sit or lie in the stroller safely and comfortably. There are many types of baby strollers on the market. In terms of frame structure, there are many folding types for consumers to choose from; in terms of equipment, the lightest baby stroller only has a seat, and the more luxurious baby strollers have additional equipment such as armrests, sunshades, dining trays or storage baskets. However, the disadvantage of these baby strollers is that they are not powered and must be pushed or pulled by manpower to move the baby stroller forward or backward.

With the advancement of technology, research on smart baby strollers is also deepening. In existing technologies, smart baby strollers usually have pressure sensors embedded in the strollers, which can sense the actual weight of the baby when the baby sits in the stroller. The baby's weight, stroller speed, mileage and ambient temperature can be viewed on the display screen on the stroller handle. The mobile application of the electronic device is wirelessly connected to the stroller to receive the above data, so that parents can understand the baby's situation in the stroller. However, existing smart strollers cannot fully allow parents to monitor the actual situation of the baby in the stroller and the environment around the stroller, and cannot fully confirm the use of the stroller, whether the baby is safe in the stroller, etc.

In view of this, the inventor has invested a lot of energy and spirit in research and development, constantly making breakthroughs and innovations in this field, hoping to solve the shortcomings of usage with novel technical means, not only to bring better products to society, but also to promote the development of the industry.

In view of the above, the main purpose of the present invention is to provide a smart stroller combined with a mobile application, which can monitor the actual situation of the baby in the stroller and the road conditions in front of the stroller through camera video, and can remotely control the stroller through the mobile application. Secondly, the smart stroller of the present invention has a fingerprint recognition unit that can simultaneously confirm the user of the smart stroller when the smart stroller is started to achieve the purpose of anti-theft; it can also record the use time, frequency and use status of the smart stroller. Furthermore, the smart stroller of the present invention has an automatic braking mechanism, a satellite positioning system, a pressure sensor and a tilt sensor to improve the safety of the smart stroller. In addition, the warning unit of the smart trolley of the present invention can generate vibration or alarm sound to remind the pusher to pay attention to the situation of the trolley, and the warning sheet can also play music and stories to improve the functionality of the trolley.

To achieve the above-mentioned purpose, the present invention provides a smart trolley including a trolley, a main control module and a power control module; wherein the trolley includes a body frame, a front wheel frame, a rear wheel frame, a seat, an armrest, a guardrail and a canopy, the bottom of the body frame is connected to the front wheel frame and the rear wheel frame, a front right wheel and a front left wheel are arranged at the bottom of the front wheel frame, a rear right wheel and a rear left wheel are arranged at the bottom of the rear wheel frame, the rear end of the body frame is connected to the armrest, the seat is installed on the body frame, the guardrail is arranged at the front end of the seat, and the canopy is arranged at the upper end of the seat. Secondly, the main control module is arranged on a base of the armrest of the cart. The main control module includes a controller, a brake controller and a first wireless communication module. The controller is electrically connected to the brake controller and the first wireless communication module.
