Patent Application
20150069727
This application claims priority to Taiwanese Patent Application No. 102132885 filed on Sep. 12, 2013, the contents of which are incorporated by reference herein.
The subject matter herein generally relates to smart strollers.
Strollers are widely used for carrying children or goods. Brake systems is very important to the strollers.
Implementations of the present technology will now be described, by way of example only, with reference to the attached figures.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein, However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures, and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the embodiments described herein.
Several definitions that apply throughout disclosure will now be presented. The term “module” refers to logic embodied in computing or firmware, or to a collection of software instruction, written in a programming language, such as Java, C, or assembly. One or more software instruction in the modules may be embedded in firmware, such as in an erasable programmable read only memory (EPROM). The modules described herein may be implemented as either software and/or computing modules and may be stored in any type of non-transitory computer-readable medium or other storage device. Some non-limiting examples of non-transitory computer-readable media include CDs, DVDs, BLU-RAY, flash memory, and hard disk drives. The term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently connected or releasably connected. The term “comprising” means “including, but not necessarily limited to”, it specifically indicates open-ended inclusion or membership in a so-described combination, group, series and the like.
In at least one embodiment, the flexible touch sensor 14 is mounted on the at least one armrest 11 to detect whether the at least one armrest 11 is grasped by a person. If the flexible touch sensor 14 determines that there is no person grasping the at least one armrest 11, the flexible touch sensor 14 generates an alert signal.
If the processor 13 detects the alert signal generated by the flexible touch sensor 14, the processor 13 controls the alert unit 17 to output an alert to prompt the persons around the smart stroller 100 that there is no person controls the smart stroller 100, and the smart stroller 100 is dangerous. In at least one embodiment, the alert unit 17 can be a loud speaker and/or a light-emitting device, accordingly, the alert can be audio signals output by the loud speaker or light emitted by the light-emitting device.
In at least one embodiment, if the processor 13 detects the alert signal generated by the flexible touch sensor 14, the processor 13 further controls the acceleration sensor 15 to detect whether the smart stroller 100 is moving. In at least one embodiment, the acceleration sensor 15 can be mounted on at least one of the wheel units 12 to detect whether the smart stroller 100 is moving. In other embodiments, the acceleration sensors 15 can be mounted on the other portions of the smart stroller 100 to detect whether the smart stroller 100 is moving.
If the acceleration sensor 15 detects that the smart stroller 100 is moving, the processor 13 controls the automatic brake units 16 to block the wheel units 12 to stop the main body 10 of the smart stroller 100 from moving. In the embodiment, the automatic brake units 16 are mounted on the wheel units 12 to block the wheel units 12 under control of the processor 13. In at least one embodiment, a brake force on each automatic brake unit 16 is gradually enhanced, thus a speed of the smart stroller 100 is gradually slowed down.
In at least one embodiment, if the processor 13 determines that the smart stroller 100 stops moving for a preset time period, the processor 13 controls the automatic brake units 16 to release the wheel units 12, thus the smart stroller 100 can be pushed by users.
It can be easily understand that the stroller 100 further can include a manual brake unit (not shown) for the user to brake manually.
The embodiments shown and described above are only examples. Many further details are often found in the art. Therefore, many such details are neither shown nor described. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the detail, including matters of shape, size, and arrangement of the parts within the principles of the present disclosure, up to and including the full extent established by the broad general meaning of the terms used in the claims. It will therefore be appreciated that the embodiments described above may be modified within the scope of the claims.
