Description

Alarm system of safety seat and safety seat

Technical Field

The utility model relates to a safety seat, in particular to a safety seat with an alarm function.

Background

Safety seats have become essential for children to ride in cars, and they provide a safe and comfortable seating space for children. Safety seats typically use a harness provided to secure a child to the seat, the harness typically having a buckle for ease of use. However, if the buckle is not engaged, the safety belt cannot stably fix the child to the safety seat. When the automobile suddenly decelerates, the child can break away from the safety seat to cause injury. At present, the safety belt buckle of a common safety seat has no warning of buckling failure, so that if a parent does not buckle the buckle at the first time, the buckle can be accidentally buckled, which causes the above risks. In addition, parents carelessly leave the children on the safety seat in the car and leave the children on the car, so that the children are injured, and the current general safety seat has no solution to the problem.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem of providing an alarm system of a safety seat and the safety seat with an alarm function, which can simultaneously sense a buckle and a seat part to confirm the riding condition of a child and send out an alarm signal according to the situation so as to remind parents or driving the buckle in order to make up the defects of the prior art.

According to an embodiment of the utility model, the safety seat is provided with a buckle assembly and at least one safety belt, the buckle assembly is provided with a buckle, and the buckle assembly is arranged on a seat part of the safety seat in a seesaw structure. The alarm system comprises a position sensor, a buckle sensor and a control module. The position sensor is arranged on the buckle assembly, and when a person sits on the safety seat, the buckle assembly can be rotated to trigger the position sensor. The buckle sensor is arranged in the buckle to sense whether the safety belt is buckled to the buckle. The control module is electrically connected with the buckle sensor and the position sensor, and sends out a first alarm signal when the position sensor is judged to be triggered and the safety belt is not buckled to the buckle. Therefore, the alarm system can judge whether the buckle is buckled or not by the position sensor and the buckle sensor when a child sits on the safety seat, so that parents or a driver can be reminded of timely buckling the buckle, and the safety of the child is guaranteed.

According to another embodiment of the present invention, a safety seat comprises a seat body, a seat belt, a buckle assembly and the alarm system. The seat body has a seat portion. The buckle assembly is arranged on the seat part in a seesaw structure. Therefore, the safety seat can judge whether the buckle is buckled or not by the position sensor and the buckle sensor when a child sits on the safety seat, so that the buckle can be buckled in time for waking parents or driving, and the safety of the child is guaranteed.

Detailed Description

Please refer to fig. 1 to 3. The safety seat 1 according to the embodiment includes a seat body 12, a seatbelt 14 (only illustrated in fig. 2 in dotted lines), and a buckle assembly 16. The buckle assembly 16 is disposed on the seat portion 122 of the seat body 12. The buckle assembly 16 includes an actuating portion 162, a rotation shaft portion 164, and a buckle portion 166. The actuating portion 162 extends upward and toward the backrest 124, and has a connecting end connected to the rotating shaft portion 164 and a free end at the other end, and the free end is relatively higher than the rotating shaft portion 164. In contrast, the buckle portion 166 extends upward and in the opposite direction of the backrest 124, and has a connecting end connected to the rotating shaft portion 164 at one end and a free end relatively higher than the connecting end, so that the buckle assembly 16 is formed into a V-shape. In addition, a buckle 1662 is provided at the free end of the buckle portion 166. The rotating shaft 164 is pivotally connected to the seat 122 via a rotating shaft or a pin, so that the buckle assembly 16 is disposed on the seat 122 in a seesaw structure. The buckle assembly 16 is detachably connected to the seat belt 14 via a buckle 1662. Thus, the child can be firmly fixed to the safety seat 1 by the harness 14.

The safety seat 1 of the present embodiment is further provided with a control circuit 10 including a control module 18, a position sensor 167 (indicated by a thick-line frame in fig. 2), and a buckle sensor 168 (indicated by a thick-line frame in fig. 2). The control module 18 is electrically connected to the position sensor 167 and the buckle sensor 168, respectively. In a preferred embodiment, the position sensor 167 and the buckle sensor 168 are both disposed within the buckle 1662. In other embodiments, the position sensor 167 may be disposed on the actuating portion 162 or the rotating shaft portion 164, but the utility model is not limited thereto. In addition, in the preferred embodiment, the position sensor 167 can be a gyroscope, but those skilled in the art should understand that other types of position sensors, such as an accelerometer, can be substituted for the gyroscope, and the utility model is not limited thereto.

In a preferred embodiment, the control circuit 10 further includes a communication module 22 electrically connected to the control module 18. In some embodiments, the communication module 22 may be a bluetooth module that may be communicatively coupled to an external mobile device 34 or an onboard vehicle control system 32 via a bluetooth interface. In other embodiments, the communication module 22 may also be a WiFi, ZigBee, RFID, or other short-range communication module.

In other embodiments, the control circuit 10 may be further provided with an alarm module 20 electrically connected to the control module 18. The alarm module 20 may be a light emitting and/or sound emitting component.

When the control module 18 senses that the actuating portion 162 is pressed down by the position sensor 167 (as shown in fig. 3, for example, when a child sits on the seat portion 122 of the safety seat 1, the hip of the child presses down the actuating portion 162) and senses that the buckle 1662 is not buckled by the buckle sensor 168, the control module 18 sends a first alarm signal S1 (indicated by an arrow in fig. 1) to the alarm module 20, and at this time, the alarm module 20 may generate a light and/or sound message in a light and/or sound manner to remind a parent or a driver to buckle the buckle 1662 in time, so as to ensure the safety of the child. In addition, in practice, the buckle sensor 168 may be, but is not limited to, a proximity sensor, a limit switch, etc., and the control module 18 may be implemented by hardware (e.g., including a circuit board, a processing chip carried thereon, a communication chip, a connection interface, and other required electronic components), software, or a combination thereof, which is not described in detail herein.

In further embodiments, the alarm of the alarm module 20 may also be implemented using a device or system external to the safety seat 1. For example, the control module 18 is connected to the vehicle-mounted control system 32 of the vehicle (with the safety seat 1 mounted thereon) through the communication module 22, and the control module 18 sends the first alarm signal S1 through the communication module 22. The vehicle-mounted control system 32 receives the first warning signal S1, and controls the speaker in the vehicle to sound, the display screen in the vehicle to generate light effect, the display text, or both according to the first warning signal S1, so as to warn the person in the vehicle. As another example, control module 18 is communicatively coupled to a mobile device 34 (e.g., a smartphone, a wireless key, etc.) via a communication module 22 (e.g., a parent or a driver in a vehicle). The smartphone receives the first warning signal S1, and controls a speaker (or an earphone communicatively connected to the smartphone) of the smartphone to sound, controls a display screen of the smartphone to display lights, text, and the like, controls the smartphone to vibrate, or executes two or three of them according to the first warning signal S1, so as to alert a holder of the smartphone (e.g., a parent or a driver). The wireless key receives the first warning signal S1 and controls the speaker of the wireless key to emit sound, controls the vibration of the wireless key, controls the wireless key to emit light (e.g., via a light emitting diode), or performs two or three of them according to the first warning signal S1 to alert the holder of the wireless key (e.g., driving). In addition, in practical applications, the communication connection can be realized through a WiFi technology, a bluetooth technology or other short-distance communication technologies, in addition to a direct wire connection. The sound may include sound, music, and the like. Corresponding mobile applications may be executed on the onboard control system 32 and the smart phone to perform the aforementioned operations (alarm according to the first alarm signal S1).

Please refer to fig. 2 to 5. In the embodiment, the actuating portion 162 and the buckle portion 166 (both connected to the rotating shaft portion 164) are fixedly connected, so that the actuating portion 162 and the buckle portion 166 also rotate together relative to the seat portion 122. When the actuating portion 162 protrudes upward (e.g., when the child is not on the safety seat 1), the rotating shaft 164 rotates forward, so that the buckle 1662 on the buckle portion 166 moves toward the front of the safety seat 1, which can avoid interfering with the parent moving the child onto the seat portion 122, and is convenient for the parent to operate (e.g., when the parent does not need to hold the child onto the seat portion 122, the parent has to release one hand to pull the buckle 1662). In addition, in this embodiment, the actuating portion 162 is biased by the torsion spring 24 to tend to move to the projecting position such that when a child is not present on the safety seat 1, the actuating portion 162 remains projecting and the catch 1662 remains in a position opposite the front side.

Please refer to fig. 1 to 3. As described above, the safety seat 1 has an alarm function, and the safety seat 1 and an external device interacting with the safety seat 1 may form a safety seat alarm system (as shown in fig. 1). When the control module 18 senses that the actuating portion 162 is pressed down by the position sensor 167, the control module 18 is communicatively connected to the mobile device 34 (e.g., a smart phone, a wireless key, etc.), and when the mobile device 34 loses the communication link with the control module 18 or the signal strength of the communication link of the mobile device 34 with the control module 18 drops to a predetermined value, the mobile device 34 alerts the driver (e.g., controls the speaker of the smartphone (or an earpiece communicatively coupled to the smartphone) to sound, controls the display screen of the smartphone to display lights, text, etc., controls the smartphone to vibrate, or performs two or three of these, as well as controls the speaker of the wireless key to sound, controls the wireless key to vibrate, controls the wireless key to illuminate (e.g., through a light emitting diode), or performs two or three of these) to alert the driver that the child is still in the safety seat 1. Similarly, the control module 18 may issue the first alarm signal S1 when it is determined that the position sensor 167 is triggered and the signal strength of the communication link with the mobile device 34 decreases to a predetermined value. Therefore, the injury of the child caused by carelessly keeping the child on the safety seat 1 in the car and moving away can be avoided. Whether the communication connection between the mobile device 34 and the control module 18 is interrupted depends on the communication technology used and the actual implementation environment. Also, in principle, the signal strength of the communication connection between the mobile device 34 and the control module 18 is related to the distance between the two, so the distance between the mobile device 34 and the control module 18 can be estimated by setting the predetermined value. Therefore, in practical application, the distance (e.g. 5 meters, 10 meters, etc.) for triggering the alarm can be set first, and then the corresponding signal strength is reversely deduced to set the predetermined value.

Please refer to fig. 1 to fig. 3. In addition, in the embodiment, when the control module 18 loses the communication connection signal with the mobile device 34 or the signal strength of the communication connection between the mobile device 34 and the control module 18 decreases to a predetermined value, the control module 18 also sends a second warning signal S2 (shown by an arrow in fig. 1) to the vehicle-mounted control system 32 of the vehicle (mounted with the safety seat 1), and the vehicle-mounted control system 32 sends out warning information and/or an outward warning (for example, controls a horn of the vehicle to sound) according to the second warning signal S2 to warn the driver that the child is still on the safety seat 1. In addition, the above description related to the predetermined value can also be applied to the predetermined value herein, and is not repeated herein. Thus, the double alarm (i.e., the alarm of the moving device 34 and the vehicle-mounted control system 32) can more effectively prevent the child from being carelessly left on the safety seat 1 in the vehicle.

Please refer to fig. 1 to fig. 3. In addition, in this embodiment, the safety seat warning system provides another warning mechanism that prevents the inadvertent retention of a child on the safety seat in the vehicle. When the control module 18 senses that the actuator 162 is depressed (e.g., a child is seated on the seat portion 122 of the safety seat 1) via the position sensor 167, the control module 18 is communicatively connected to the in-vehicle control system 32. Then, when the vehicle-mounted control system 32 senses that the vehicle is turned off and the door of the vehicle is opened, the vehicle-mounted control system 32 gives an alarm (for example, controls the speaker in the vehicle to make a sound, controls the display screen in the vehicle to generate a light effect, displays text, or the like, or executes two or three of them) to warn the driver that the child is still on the safety seat 1. In other embodiments, the control module 18 may send a short message to the caregiver's mobile device 34 via the communication module 22, or notify the alarm system that a child is left in the car, etc. In addition, in practical applications, the above-mentioned various alarm mechanisms for preventing the child from being carelessly left in the safety seat 1 in the car can be used together.

Please refer to fig. 6. In practical applications, the safety seat warning system can be implemented in principle according to the flow shown in fig. 6. For the description of the components of the safety seat 1, please refer to the related description and corresponding drawings, which are not repeated herein. In step S102, the control module 18 determines whether the actuating portion 162 is pressed by the position sensor 167. If not, the process returns to step S102. If yes, the control module 18 determines whether the buckle 1662 is fastened by the buckle sensor 168, as shown in step S104. If not, the control module 18 sends a first alarm signal S1, as shown in step S106; the alarm module 20 receives the first alarm signal S1 and alarms according to the first alarm signal S1, as shown in step S108. If it is determined that the child is present, various alarm mechanisms for avoiding the child from being carelessly left in the car seat 1 are described below. In addition, the control module 18 is now, in principle, already in communication with the mobile device 34 and the vehicle control system 32 of the vehicle.

Please refer to fig. 6. In step S110, the mobile device 34 determines whether the communication connection signal with the control module 18 is lost or the signal strength of the communication connection between the mobile device 34 and the control module 18 is reduced to a predetermined value. If no, the process returns to step S110. If yes, the mobile device 34 gives an alarm, as shown in step S112. In addition, in step S114, the control module 18 determines whether the communication connection signal with the mobile device 34 is lost or the signal strength of the communication connection between the mobile device 34 and the control module 18 is reduced to a predetermined value. If no, the process returns to step S114. If yes, the control module 18 sends a second warning signal S2 to the vehicle-mounted control system 32, and the vehicle-mounted control system 32 gives an alarm according to the second warning signal S2, as shown in step S116. Further, as shown in step S118, the in-vehicle control system 32 determines whether the vehicle is turned off and the doors of the vehicle are opened. If no, the process returns to step S118. If yes, the in-vehicle control system 32 gives an alarm, as shown in step S120.

As mentioned above, the safety seat alarm system is applied to the safety seat 1, and can remind the parents or the driver to fasten the buckle 1662 in time to ensure the child sitting on the safety seat 1, and avoid the injury of the child caused by the careless retention of the child on the safety seat 1 in the car and the accident of the child getting away from the car. In practical applications, the safety seat 1 may be provided with an energy storage device (e.g., a battery) to supply power to the electronic devices disposed on the safety seat 1, which is not described herein.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
