DETAILED DESCRIPTION

[0032] Here, the technical solutions in the embodiments (or "implementations") of the present application will be described clearly and completely in conjunction with the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0033] If there are terms involving directional indications or positional relationships in the embodiments of the present application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings); if the specific posture changes, the directional indication or positional relationship will also change accordingly. In addition, the terms "first", "second", etc. involved in the embodiments of the present application are only used for the purpose of convenience of description and cannot be understood as indicating or implying relative importance.

[0034] like Figures 1 to 4 As shown, the child seat of the present application includes an upper seat back 1, a lower base 2, an adjustment component 3, a first sensor 4 and a second sensor 5. The upper seat back 1 is arranged on the adjustment component 3 and can slide relative to the adjustment component 3. The adjustment component 3 is rotatably arranged on the lower base 2, and the upper seat back 1 can slide and rotate relative to the lower base 2 through the adjustment component 3. Such a configuration allows the child seat to be adjusted at multiple angles and in multiple directions, thereby allowing the child seat to have multiple sitting states, thereby improving the applicability of the child seat to be suitable for children of different ages.

[0035] In one embodiment, the upper seat back 1 includes a safety belt 11 and a seat back body 12. The safety belt 11 is arranged on the seat back body 12, and the seat back body 12 is arranged on the adjustment component 3. The lower base 2 includes a base body 21, a mounting member 22 and a support leg 23. The adjustment component 3 is arranged on the base body 21, and the base body 21 is adjustably mounted on the mounting member 22, and the mounting member 22 is used to connect with the vehicle seat. In this arrangement, by adjusting the position between the base body 21 and the mounting member 22, the distance between the child seat and the vehicle seat can be changed, so that the child seat can be more safely connected to the vehicle seat.

[0036] The mounting member 22 is provided with an ISOFIX (child safety seat fixing system) portion 221, and the ISOFIX portion 221 is connected to the vehicle seat. The ISOFIX portion 221 improves the convenience and safety of connecting the child seat to the vehicle seat.

[0037] The support leg 23 is rotatably connected to the base body 21 and is located at the front end of the base body 21. The support leg 23 is retractable so that when the child seat is installed, the support leg 23 can contact the vehicle floor, thereby supporting the base body 21 and improving the stability of the child seat after installation.

[0038] Further integration Figure 5 to Figure 6 As shown, in one embodiment, the child seat includes a sitting position and an alarm position. The sitting position includes a forward state and a rearward state. Further, the base body 21 includes a connecting seat 211 and an extended seat back 212 protruding from the connecting seat 211, and the seat back body 12 is arranged on the connecting seat 211 through an adjustment component 3. When the upper seat back 1 is away from the extended seat back 212 and toward the front end of the base body 21, the child seat is in a forward state. When the upper seat back 1 is toward the extended seat back 212 and toward the rear end of the base body 21, the child seat is in a rearward state. It is worth noting that regardless of whether the child seat is in the forward state or the rearward state, the upper seat back 1 can be slidably adjusted relative to the lower base 2.

[0039] When the child seat is moved from the forward state to the rearward state or from the rearward state to the forward state, the upper seat back 1 rotates 180 degrees relative to the lower base 2. Each position of the child seat when it is moved from the forward state to the rearward state or from the rearward state to the forward state is an alarm position.

[0040] Further integration Figures 7 and 8 As shown, in one embodiment, the adjustment component 3 includes a component body 31 and an indication area 32. The component body 31 is connected between the upper seat back 1 and the lower base 2, and the indication area 32 is provided on the component body 31. Furthermore, the indication area 32 is located on the side of the component body 31 away from the upper seat back 1 and facing the lower base 2. The color of the indication area 32 is different from the color of the component body 31. Such a setting can improve the accuracy of the detection of the indication area 32, and then the status of the child seat can be confirmed more accurately, and the warning of the child seat can be more timely.

[0041] The first sensor 4 and the second sensor 5 can both be used to sense the color of the component body 31 and the indication area 32, and when one of the first sensor 4 and the second sensor 5 corresponds to the indication area 32, the child seat is in the sitting position. Specifically, when the first sensor 4 corresponds to the indication area 32 and the second sensor 5 corresponds to the component body 31, the child seat is in the forward state. When the second sensor 5 corresponds to the indication area 32 and the first sensor 4 corresponds to the component body 31, the child seat is in the backward state.

[0042] In another embodiment, when the first sensor 4 corresponds to the indicator area 32 and the second sensor 5 corresponds to the component body 31, the child seat is in the rearward state. When the second sensor 5 corresponds to the indicator area 32 and the first sensor 4 corresponds to the component body 31, the child seat is in the forward state.

[0043] In one embodiment, when both the first sensor 4 and the second sensor 5 correspond to the component body 31, the child seat is in the alarm position. That is, during the rotation of the child seat from the forward state to the rearward state or from the rearward state to the forward state, if the upper seat back 1 is not completely rotated relative to the lower base 2, the first sensor 4 and the second sensor 5 will both correspond to the component body 31, and then alarm the error state of the child seat being in the alarm position.

[0044] In order to improve the detection accuracy of the first sensor 4 and the second sensor 5, the component body 31 and the indicator area 32 use colors with a large color difference. Preferably, the color of the component body 31 is black, and the color of the indicator area 32 is white. Or the color of the component body 31 is white, and the color of the indicator area 32 is black. Of course, the component body 31 can also be other colors with darker hues, and the indicator area 32 can be other colors with lighter hues; or the component body 31 can also be other colors with lighter hues, and the indicator area 32 can be other colors with darker hues.

[0045] In one embodiment, the component body 31 includes a base member 311 and a guide rail 312. The base member 311 is rotatably connected to the lower base 2, the upper seat back 1 is slidably arranged on the guide rail 312, and the indication area 32 is located at the base member 311. The guide rail 312 is fixed to the base member 311, and part of the guide rail 312 passes through the base member 311. The guide rail 312 is provided with a guide groove 3121, and the guide groove 3121 is in an arc shape, and the upper seat back 1 is connected to the guide groove 3121. The upper seat back 1 can slide along an arc track relative to the lower base 2 through the guide groove 3121. Preferably, two guide rails 312 are provided, and are symmetrically arranged on the base member 311.

[0046] In order to improve the detection accuracy of the first sensor 4 and the second sensor 5, the colors of the base member 311 and the guide rail 312 are different from the color of the indication area 32. The color of the indication area 32 is white, and the color of the base member 311 is the same as the color of the guide rail 312, which is black; or the color of the indication area 32 is black, and the color of the base member 311 and the color of the guide rail 312 are white.

[0047] In another embodiment, the color of the base plate 311 and the color of the guide rail 312 may also be different colors with similar hues, and both are greatly different from the color of the indication area 32 .

[0048] In one embodiment, the indication area 32 includes a first indication area 321 and a second indication area 322. In order to improve the detection accuracy of the first sensor 4 and the second sensor 5, the first indication area 321 and the second indication area 322 are arranged on the base plate 311 and are arranged at intervals from each other. At the same time, the first indication area 321 and the second indication area 322 are also located between the two guide rails 312. Further, the first indication area 321 and the second indication area 322 are arranged diagonally on the base plate 311. Since the first sensor 4 and the second sensor 5 are installed at different positions, in order to make the first indication area 321 and the second indication area 322 easier to detect, the first indication area 321 is closer to the center of the base plate 311 than the second indication area 322.

[0049] The first indication area 321 and the second indication area 322 have the same color, and the base plate 311 and the guide rail 312 have colors different from the first indication area 321 or the second indication area 322. Further, the first indication area 321 and the second indication area 322 have white colors, and the base plate 311 has the same color as the guide rail 312, which is black. Alternatively, the first indication area 321 and the second indication area 322 have black colors, and the base plate 311 and the guide rail 312 have white colors.

[0050] When the first sensor 4 corresponds to the first indication area 321, the child seat is in the forward state. When the second sensor 5 corresponds to the second indication area 322, the child seat is in the rearward state. Further, when the child seat is in the forward state, the first sensor 4 corresponds to the first indication area 321, and the second sensor 5 corresponds to the guide rail 312 or the base plate 311. When the child seat is in the rearward state, the second sensor 5 corresponds to the second indication area 322, and the first sensor 4 corresponds to the guide rail 312 or the base plate 311.

[0051] In another embodiment, when the first sensor 4 corresponds to the first indication area 321, the child seat is in the rearward state. When the second sensor 5 corresponds to the second indication area 322, the child seat is in the forward state. Further, when the child seat is in the rearward state, the first sensor 4 corresponds to the first indication area 321, and the second sensor 5 corresponds to the guide rail 312 or the base plate 311. When the child seat is in the forward state, the second sensor 5 corresponds to the second indication area 322, and the first sensor 4 corresponds to the guide rail 312 or the base plate 311.

[0052] In one embodiment, the first sensor 4 and the second sensor 5 are disposed on the lower base 2, and to prevent the first sensor 4 and the second sensor 5 from interfering with each other, the first sensor 4 and the second sensor 5 are spaced apart. The first sensor 4 and the second sensor 5 are preferably infrared sensors.

[0053] Further integration Fig. 9 As shown, in one embodiment, the child seat includes a pressure sensor 6, a time module (not shown), a processor 7 and a reminder module (not shown). The pressure sensor 6, the time module and the reminder module are all electrically connected to the processor 7 to receive signals fed back by the pressure sensor 6 and the time module. The processor 7 can control the reminder module to start and work.

[0054] The pressure sensor 6 is arranged at the bottom of the upper seat back 1, and can be used to sense whether there is someone sitting in the child seat and detect the weight of the occupant. The time module is used to record the birth date of the occupant and the current time in real time. The time module can record multiple sets of birth date data, thereby allowing the child seat to be recycled.

[0055] The first sensor 4 and the second sensor 5 are also electrically connected to the processor 7, and the processor 7 is used to receive signals from the first sensor 4 and the second sensor 5 to control the reminder module to start. The reminder module includes a voice module and / or a wireless connection module. The wireless connection module can be connected to a mobile terminal such as a vehicle computer, a mobile phone, a computer, etc. The reminder module can make reminder notifications through voice, text, pictures, videos, etc. The reminder module is arranged on the upper seat back 1 and / or the lower base 2. Of course, the reminder module can also be a buzzer and is arranged on the processor 7.

[0056] In one embodiment, the first sensor 4 and the second sensor 5 are fixed on the processor 7 and are respectively located at opposite ends of the processor 7. The processor 7 is disposed on the lower base 2 and is located between the lower base 2 and the base plate 311. In the up and down direction of the child seat, the first sensor 4 and the second sensor 5 are disposed opposite to the first indication area 321 and the second indication area 322.

[0057] In the child seat of the present application, when the pressure sensor 6 senses the seating pressure, the signal is fed back to the processor 7, and then the first sensor 4 and the second sensor 5 are turned on for detection. If the child seat position is detected to be abnormal, the reminder module will broadcast it. Whether the seat belt is engaged in place, whether the mounting part 22 is fixed in place, and whether the support leg 23 is extended in place are all within the detection range of the child seat.

[0058] The child seat of the present application is provided with an adjustment component 3 so that the upper seat back 1 can rotate relative to the lower base 2, so that the child seat has multiple sitting states, thereby improving the applicability of the child seat. At the same time, by providing a first sensor 4 and a second sensor 5, the sitting state of the child seat can be detected, and an alarm can be issued for an incorrect sitting state of the child seat, thereby improving the safety of the child seat. In addition, the first sensor 4 and the second sensor 5 detect the component body 31 and the indicator area 32, and the component body 31 and the indicator area 32 have different colors, which can improve the accuracy of the detection of the first sensor 4 and the second sensor 5, and the warning of the child seat is more timely.

[0059] Further integration Figure 10 to Figure 11 As shown, the present application also provides a method for determining the seat usage status of a child seat, comprising:

[0060] Step S1, receiving a ride signal;

[0061] Step S2, turning on the first sensor 4 and the second sensor 5;

[0062] Step S3, analyzing the color data fed back by the first sensor 4 and the second sensor 5 to determine whether the child seat is in the sitting position; if not, start the reminder module.

[0063] The sitting signal is the sitting pressure felt by the pressure sensor 6. The seat use status determination method can automatically confirm the age of the occupant based on the birth date of the occupant and the current time recorded by the time module, and automatically match the correct seat sitting position in combination with the occupant's weight. If the current state of the child seat does not conform to the correct seat sitting position, the reminder module will be activated to alarm. If the current state of the child seat conforms to the correct seat sitting position, the child seat is in a silent state. Of course, the reminder module can also be used to remind the child seat that the sitting position is correct.

[0064] In one embodiment, step S3 further includes: analyzing the information fed back by the pressure sensor 6 and the data fed back by the time module to determine whether the child seat is in the correct sitting position; if not, starting the reminder module.

[0065] In one embodiment, in order to improve the degree of protection of the child seat for the occupant, the child seat is rearward facing for occupants under N months old, and forward facing for occupants over N months old. Specifically, the value of N is preferably 12, that is, the child seat is rearward facing for occupants under 12 months old, and forward facing for occupants over 12 months old. Of course, the value of N may also be 8 or 14, etc., and this is not limited herein.

[0066] Step S3 also includes: determining whether the age of the passenger is within N months;

[0067] If yes, determine whether the second sensor 5 corresponds to the second indication area 322; if no, start the reminder module;

[0068] If it is determined that the age of the occupant is above N months, it is determined whether the first sensor 4 corresponds to the first indication area 321; if not, the reminder module is activated.

[0069] In another embodiment, when the first sensor 4 corresponds to the first indication area 321 , the child seat is in the rearward state; and when the second sensor 5 corresponds to the second indication area 322 , the child seat is in the forward state.

[0070] The step S3 includes: determining whether the age of the passenger is within N months;

[0071] If yes, determine whether the first sensor 4 corresponds to the first indication area 321; if no, start the reminder module;

[0072] If it is determined that the age of the occupant is above N months, it is determined whether the second sensor 5 corresponds to the second indication area 322; if not, the reminder module is activated.

[0073] In one embodiment, step S3 also includes: determining whether the mounting member 22 is installed in place; if not, starting the reminder module; determining whether the support leg 23 is extended in place; if not, starting the reminder module; determining whether the seat belt 11 is engaged in place; if not, starting the reminder module.

[0074] In one embodiment, step S3 further includes: starting a voice module to play voice; and / or starting a wireless connection module to remind via a mobile terminal.

[0075] The seat use status determination method of the present application can more accurately match the seat sitting position suitable for the occupant by combining the detection of the age and weight of the occupant, thereby improving the safety of the child seat. In addition, by detecting the component body 31 and the indicator area 32 through the first sensor 4 and the second sensor 5, the detection accuracy of the first sensor 4 and the second sensor 5 can be further improved, and the early warning of the child seat can be more timely.

[0076] The present application also provides a storage medium on which a computer program is stored, and the storage medium can be read by a computer. When the computer program is executed by a processor, the seat usage status determination method as described above is implemented.

[0077] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without causing conflicts. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the drawings; all modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of this application should be included in the scope of protection of this application.
