Description

Technical Field

[0001] The present disclosure relates to the technical field of safety seats, and in particular to a base and a safety seat. Background Art

[0002] A child safety seat is a device that is installed on a car seat and restrains infants and young children on it through a restraining device. In the event of emergency braking or accidental collision of the car, the safety seat can reduce the impact force on the infant and young children through its shell and limit the movement of the infant and young children's body through its restraining device to reduce the injuries suffered by the infant and young children in the accident and ensure the safety of the infant and young children in the car. Generally speaking, the direction of a child safety seat is the forward direction of the car, but for very young infants and young children, adjusting the direction of the child safety seat to a rear-facing position can provide better protection and cushioning for the child. Therefore, in recent years, more rotatable child safety seats have appeared to achieve the effect of being placed in both forward and reverse directions.

[0003] In order to ensure the safety of children during driving, for children under 76 cm in height, the seat must be installed backward (reverse) so that the child can get better protection and cushioning during driving. However, in real life, when parents connect the seat to the base, they sometimes install the seat by mistake, which brings certain safety hazards to children. Therefore, it is urgent to develop a base with a reminder function to remind parents to avoid misinstallation of the seat. Utility Model Content

[0026] In order to enable those skilled in the art to better understand the technical solution of the present disclosure, the present disclosure is described in detail, clearly and completely in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present disclosure and are not used to limit the present disclosure.

[0027] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0028] Please refer to Figure 1 to Figure 3As shown, a base includes a base, a rotating mechanism and a signal sensing mechanism, the signal sensing mechanism is used to sense that the rotating mechanism is connected to a basket or a seat, and the installation state of the basket and the seat, the base is provided with a rotating part, the rotating mechanism is rotatably connected to the rotating part, the basket or the seat is connected to the rotating mechanism and rotates with the rotating mechanism, the base is provided with a group selection mechanism, the group selection mechanism is used to manually select the group corresponding to the child in use, the cradle or the seat or the base is provided with a controller, the group selection mechanism and the signal sensing mechanism are respectively connected to the controller. The group selection mechanism selects different groups to transmit different signals to the control center, the objects connected to the rotating mechanism or the states of the objects are different, the signal sensing mechanism transmits different signals to the control center, when the signal transmitted by the group selection mechanism to the control center does not match the signal transmitted by the signal sensing mechanism to the control center, the control center sends a prompt signal for reminding the user of the wrong installation, so as to avoid the safety hazards caused by the wrong installation of the parents, and further ensure the safety of the children when riding in the car. It should be noted that the controller is generally installed on the base, and in a few cases, the controller can also be set on the basket or the seat. In the present disclosure, the signal sensing mechanism can be set on the base or on the rotating mechanism. The signal sensing mechanism senses whether the rotating mechanism is connected to a basket or a seat, and the installation status of the basket and the seat through the Hall effect. For example, the signal sensing mechanism is a Hall sensor, a magnet is installed on the basket, and no magnet is installed on the seat. The signal sensing mechanism determines the basket or the seat, and the installation status of the basket and the seat by sensing changes in the magnetic signal. The specific structure and principle of the signal sensing mechanism can be found in another case of our company, which will not be repeated here.

[0029] Please also see Figure 6 and Figure 7 As shown, in one embodiment of the present disclosure, the base includes a first shell 1 and a second shell 2, the second shell 2 is arranged below the first shell 1, and the rotating part is arranged on the first shell 1. A connecting frame 9 is arranged on the second shell 2, a slide groove 12 is arranged on the connecting frame 9, and the adjusting member 5 is slidably connected with the slide groove 12. Specifically, the slide groove 12 is arranged below the adjusting member 5, and the arrangement of the slide groove 12 not only reduces the friction between the adjusting member 5 and the connecting frame 9, but also plays a role of limiting, so that the adjusting member 5 is more stable and reliable during the sliding process.

[0030] like Figures 4 to 7As shown, it should be noted that the group selection mechanism includes a first sensor 10 and a second sensor 11, which are respectively arranged on both sides of the adjusting member 5. When the adjusting member 5 is pushed to slide the adjusting member 5, the adjusting member 5 can touch the first sensor 10 or the second sensor 11. When the adjusting member 5 touches the first sensor 10, the first sensor 10 transmits a first signal to the controller; when the adjusting member 5 touches the second sensor 11, the second sensor 11 transmits a second signal to the controller. A touch portion 6 is arranged on the adjusting member 5, and the touch portion 6 is a convex structure, which is used to enhance the friction when pushing the adjusting member 5, so as to facilitate operation. A waist-shaped hole is arranged on the side of the first shell 1, and the touch portion 6 is exposed from the waist-shaped hole. Pushing the touch portion 6 causes the adjusting member 5 to slide along the slide groove 12. A first label and a second label are respectively arranged on both sides of the waist-shaped hole. The first label is arranged close to the first sensor 10, and the second label is arranged close to the second sensor 11. Specifically, the first label and the second label represent two different groups respectively, and different groups represent children of different height ranges. The first label and the second label can be distinguished by different colors or texts. The first label represents children with a height of 40-75cm, and the second label represents children with a height of 76-105cm. When the adjustment member 5 is pushed to the first sensor 10, the first sensor 10 transmits a first signal to the controller, indicating that the child using the base is a child with a height of 40-75cm. When the adjustment member 5 is pushed to the second sensor 11, the second sensor 11 transmits a second signal to the controller, indicating that the child using the base is a child with a height of 76-105cm.

[0031] Furthermore, the signal sensing mechanism is a sensor of electrical signals, and the basket is installed on the rotating mechanism in the forward direction, and the signal sensing mechanism transmits a fifth signal to the controller; the basket is installed on the rotating mechanism in the reverse direction, and the signal sensing mechanism transmits a sixth signal to the controller; the seat is installed on the rotating mechanism in the forward direction, and the signal sensing mechanism transmits a seventh signal to the controller; the seat is installed on the rotating mechanism in the reverse direction, and the signal sensing mechanism transmits an eighth signal to the controller; when the first sensor 10 transmits a first signal to the controller, and the signal sensing mechanism transmits a sixth signal to the controller, the controller will not issue a prompt signal at this time, otherwise, the controller will issue a prompt signal; when the second sensor 11 transmits a second signal to the controller, and the signal sensing mechanism transmits a sixth signal or an eighth signal to the controller, the controller will not issue a prompt signal at this time, otherwise, the controller will issue a prompt signal. The first sensor 10 transmits a first signal to the controller, indicating that the base is used by a child with a height of 40-75 cm. Children in this stage can only use a carrycot, and the carrycot needs to be installed in reverse. Therefore, when the signal sensing mechanism transmits a sixth signal to the controller, it indicates that the carrycot is installed in reverse on the rotating mechanism. If the carrycot is installed correctly, the controller will not issue a prompt signal. If the signal sensing mechanism transmits other signals except the sixth signal to the controller, it indicates that the carrycot is not correctly installed on the rotating mechanism or that what is installed on the rotating mechanism is not the carrycot but a seat. The second sensor 11 transmits a second signal to the controller, indicating that the base is used by children with a height of 76-105 cm. Children in this stage are still young and have a weak sense of safety. They can use both a basket and a seat, but the basket and the seat must be installed in reverse. When the signal sensing mechanism transmits the sixth signal or the eighth signal to the controller, it indicates that the basket or the seat is installed in reverse on the rotating mechanism at this time. The installation state of the basket or the seat matches the child at this stage, and the controller will not issue a prompt signal. If the signal sensing mechanism transmits other signals to the controller except the sixth signal and the eighth signal, it indicates that the basket or the seat is not correctly installed on the rotating mechanism. In this way, the safety hazards caused by improper installation of the basket or the seat can be effectively avoided.

[0032] For further information, see Figure 1 and Figure 3 As shown, the rotating mechanism includes a cover plate 3 and a bracket 8, the bracket 8 is arranged on the rotating part and can rotate on the rotating part, the cover plate 3 is connected to the bracket 8, the cover plate 3 rotates with the rotation of the bracket 8, and the basket or the seat is connected to the cover plate 3. The rotating part is a circular guide rail 7, the bracket 8 is provided with a mounting opening, and the guide rail 7 is partially embedded in the mounting opening. In order to make the child safer and more reliable when using the base, the base is also connected to a support leg 4.
