Detailed Description

The present application is further described with reference to the accompanying drawings and the detailed description, and it should be noted that, in the present application, the embodiments or technical features described below may be arbitrarily combined to form a new embodiment without conflict.

The first embodiment is as follows:

referring to fig. 1 and 3, the present embodiment provides a child safety seat. The child safety seat includes a base, a back, and a connection assembly. The lower portion of the backrest is connected with the rear portion of the base. The connecting assembly is arranged on the lower portion of the backrest and/or the rear portion of the base and used for being connected with an automobile seat. The coupling assembling includes locking mechanical system, locking mechanical system can prevent when being in the locked state the children's safety seat follow break away from on the car seat, locking mechanical system is when the unlocked state the children's safety seat can follow break away from on the car seat.

Wherein, the lower part of the backrest can be connected with the rear part of the base through a pivot. The child safety seat has an unfolded state shown in fig. 1 and a folded and stowed state shown in fig. 2, and when the child safety seat is switched from the unfolded state to the folded and stowed state, the base pivots relative to the backrest such that the upper surface of the base is brought closer to the front surface of the backrest. The child safety seat has an unfolded state and a folded and stored state, and can be folded and stored when not needed. Folding children's safety seat of accomodating can not influence pleasing to the eye in the car to realize children's safety seat's stealthy effect. In addition, when an adult wants to take, as long as make children's safety seat in folding state of accomodating, need not dismantle children's safety seat, need install again when having avoided children to take, it is more convenient to use, has avoided the frequent dismantlement of safety seat to cause the trouble and has dismantled the difficult problem that the back is difficult to accomodate, has improved user's experience.

Wherein, coupling assembling can match car seat's the interface of predetermineeing in order to fix child safety seat on car seat. The preset interface of the car seat may be Isofix (International Standards Organization FIX) interface, Latch (Lower Anchors and teethers for childrens) interface, and other preset interfaces. The locking or the disengagement of the child safety seat on the car seat is realized by the locking mechanism of the connecting assembly.

The child safety seat further comprises an operation button, a biological information acquisition assembly, a transmission mechanism, a power mechanism and a controller. The operation button is used for receiving the pressing operation of a user. The biological information acquisition assembly is used for acquiring biological information to be identified. When the transmission mechanism is at a first position, the locking mechanism is in a locking state, and when the transmission mechanism is at a second position, the locking mechanism is in an unlocking state; alternatively, the locking mechanism may remain locked when the actuator is in the first position and may be switchable between the locked and unlocked states when the actuator is in the second position. The power mechanism is used for driving the transmission mechanism to move from the first position to the second position, or driving the transmission mechanism to move from the second position to the first position. In some embodiments, the operation buttons may be touch operation buttons.

The power mechanism can be a micro motor, and can also be other devices which drive the transmission mechanism to move through electric power. The biological information acquisition component can be a fingerprint information acquisition component, a finger vein information acquisition component, a human face information acquisition component, a palm vein information acquisition component and the like.

The switching between the locking state and the unlocking state of the locking mechanism can be realized by the change of the displacement of the power mechanism driving the transmission mechanism between the first position and the second position. The locking mechanism can lock the child safety seat in a locking state so as to achieve the effect of safety protection of a child using the child safety seat. When the locking mechanism is in an unlocked state, the child safety seat can be released from being locked, so that the child safety seat is separated from the automobile seat.

The controller is electrically connected with the operation button, the biological information acquisition assembly and the power mechanism, and first-class authentication biological information is stored in the controller. The biological information may be fingerprint information, finger vein information, face information, palm vein information, etc.

Referring to fig. 3, the controller is configured to perform the steps of:

step S101, when the operation button receives a pressing operation, the biological information acquisition assembly is used for acquiring biological information to be identified, and the biological information to be identified is compared with the first type authentication biological information.

Step S102, when it is detected that the biometric information to be identified is matched with one of the first type authentication biometric information, a permission operation instruction is sent to the power mechanism, so that the power mechanism drives the transmission mechanism to move from a current position to another position according to the permission operation instruction, wherein the current position is one of the first position and the second position, and the another position is a position other than the current position in the first position and the second position.

And step S103, when the fact that the biological information to be identified is not matched with any one of the first type of authentication biological information is detected, sending an operation prohibiting instruction to the power mechanism so that the transmission mechanism keeps the current position unchanged.

The first type of authentication biological information may be one or more pieces of biological information of the user stored in advance, and the user may also enter new biological information at any time according to needs. For example, fingerprint information of the right thumb of the user is first-type authentication biological information which is stored in advance, and when the left side of the child safety seat is unlocked, the right thumb is used for conveniently unlocking through the biological information acquisition assembly; but when the user unlocks on children's safety seat right side, it is more convenient to use the left hand forefinger to carry out the unblock through biological information acquisition subassembly, and the user can type the fingerprint information of left hand forefinger into first type authentication biological information. The first type of authentication biological information can also be biological information of a plurality of pre-stored users, and the requirement that the child safety seat can be unlocked by the plurality of users can be met.

In a specific application, a parent drives a vehicle with three persons for going out, the child sits on the child safety seat in a locked state, and the first type of authentication biological information only stores finger vein information of the three persons. In the driving process of the automobile, a child presses, tears or beats the operation button and/or the biological information acquisition assembly by hands, and because the finger vein information of the child is not matched with the first type authentication biological information, the locking mechanism of the child safety seat can keep a locking state, and the child safety seat is prevented from being separated from the automobile seat. Later need take out child safety seat from the vehicle, Zhang three can press operating button and utilize biological information collection subassembly to gather the biological information that waits to discern, because Zhang three finger vein information and first type authentication biological information phase-match, child safety seat's locking mechanical system all can switch to the unblock state, makes child safety seat can break away from car seat.

In some embodiments, the first type of authentication biometric information may further include biometric information of public service personnel such as school teachers, policemen, doctors, nurses, etc., which is pre-entered or pre-stored to the controller.

From this, through comparing the biological information of treating discernment that gathers, according to current unblock people's identification result, whether control children's safety seat's locking mechanical system unblock, improved children and used children's safety degree of safety seat, solve the problem that current children's safety seat unblock does not need authentication just can the unblock.

In some embodiments, the biometric information collection component is a fingerprint information collection component, the biometric information to be recognized and the first type authentication biometric information are fingerprint information, and the biometric information collection component and the operation button are integrated.

Therefore, when the biological information acquisition assembly and the operation button are integrated, the user finishes the acquisition of the biological information to be identified while pressing the operation button, and compared with an ordinary child safety seat, the perception of an unlocking step cannot be increased in the aspect of user experience. On one hand, the learning cost of the user is reduced; on one hand, due to the integrated design of the biological information acquisition assembly and the operation buttons, the unlocking step is more coherent, and the user experience is improved.

In some embodiments, the biometric information collection component is a vein information collection component, and the biometric information to be identified and the first type of authentication biometric information are vein information; or, the biological information acquisition component is a face information acquisition component, and the biological information to be recognized and the first type authentication biological information are face information.

Compared with face recognition and fingerprint recognition, the vein recognition precision is higher, and the recognition can be executed only by living bodies, so that the condition that face information and fingerprint information are stolen for identity verification in recognition modes such as face recognition, fingerprint recognition and the like is avoided. When the biological information to be identified and the first type of authentication biological information are vein information, the identification can be carried out only by actively extending out the finger of the user, and the intention of the user is fully respected.

Compared with fingerprint identification and vein identification, the identification of the human face does not need direct contact between limbs and a biological information acquisition component. When the biological information to be identified and the first type of authentication biological information are face information, the biological information acquisition component can be acquired from a user at a flexible distance, and the user experience is good.

Therefore, a proper biological information acquisition assembly can be selected according to the will of the user so as to meet various requirements of the user.

In some embodiments, the locking mechanism is in a locked state when the transmission mechanism is in the first position and the locking mechanism is in an unlocked state when the transmission mechanism is in the second position; the transmission mechanism and the locking mechanism remain relatively stationary. Therefore, when the transmission mechanism and the locking mechanism are kept in a relatively static arrangement, the transmission mechanism can control the locking mechanism to switch between the unlocking state and the locking state more quickly. When the locking device is operated, the user can not feel the delay of the switching of the locking state or the unlocking state, and better use experience is provided for the user.

In particular, the transmission mechanism and the locking mechanism may be integrated. Through the integrated setting of drive mechanism and locking mechanical system, reduced child safety seat unblock state and the locking state switching process in-process mechanical failure's possibility, improved child safety seat's stability.

In some embodiments, the locking mechanism is in a locked state when the transmission mechanism is in the first position and the locking mechanism is in an unlocked state when the transmission mechanism is in the second position; the transmission mechanism and the locking mechanism can move relatively. The transmission mechanism and the locking mechanism can be in transmission modes such as chain transmission, belt transmission or gear transmission, and the like, so that a preset transmission ratio is realized between the transmission mechanism and the locking mechanism, and the driving of the power mechanism is buffered. Therefore, the generation of vibration and noise in the unlocking or locking state switching process of the child safety seat is avoided.

Specifically, drive mechanism is provided with first gear portion, locking mechanical system is provided with second gear portion, drive mechanism with locking mechanical system passes through first gear portion with gear drive is realized to the second gear portion. The transmission mechanism and the locking mechanism realize a preset transmission ratio through the meshing transmission between the gears and the adjustment of the tooth numbers of the first gear part and the second gear part, and the transmission precision and the efficiency are high; the first gear part and the second gear part have good transmission relation, so that the gear transmission is more stable and the reliability is high; and the involute characteristic of the gear determines that the gear transmission can ensure constant instantaneous transmission ratio. Therefore, the gear transmission is adopted between the transmission mechanism and the locking mechanism, the unlocking or locking state switching process of the child safety seat is more stable, and the user experience is good.

In some embodiments, the locking mechanism remains locked when the transmission mechanism is in the first position and is switchable between a locked state and an unlocked state when the transmission mechanism is in the second position. The child safety seat may further include: and the detection sensor is used for detecting the position of the transmission mechanism and sending the position to the controller.

The controller may be further configured to perform the steps of: and when the position of the transmission mechanism is detected to be the second position, sending an unlocking instruction to the locking mechanism so as to enable the locking mechanism to be switched to an unlocking state.

Therefore, when the detection sensor detects that the position of the transmission mechanism is not the second position, the unlocking instruction is not sent; only when the position that detection sensor detected drive mechanism is the second position, locking mechanical system switches to the unblock state, does not need the user to manually remove children's safety seat and car seat's fixed, and intelligent degree is high.

In some embodiments, the child safety seat may further include a pressure sensor disposed on the base for sensing a pressure applied to the base; the controller can be electrically connected with the pressure sensor, and the pressure sensor is used for detecting whether the pressure applied to the base is greater than a preset pressure threshold value. The preset pressure threshold may be an initial value set according to the average level of physical development of children in the product supply area, for example, 5kg, 6kg or 8kg, or may be a pressure threshold set by the user according to actual conditions.

The controller can be further configured to detect pressure applied to the base through the pressure sensor when the operation button receives a pressing operation, and when the pressure applied to the base is smaller than a preset pressure threshold value, if the operation button receives the pressing operation, the biological information to be identified is collected by the biological information collection assembly, the biological information to be identified is compared with the first type of authentication biological information, and whether the locking mechanism of the child safety seat is unlocked or not is controlled according to a comparison result. When the pressure that the base received is not less than preset pressure threshold value, even if operating button received the press operation, biological information collection subassembly can not gather the biological information of treating discernment yet. The method can pointedly select the biological information to be identified to be compared with the first type of authentication biological information, thereby avoiding potential safety hazards caused by misoperation and unlocking of a user and reducing the data processing pressure of the child safety seat.

In one particular application, when a child is not older than 1 year, the user may set the stress threshold to 2 kg; when the user's child ages to 4 years old, the user may set the stress threshold to 8 kg; when the user's child ages up to 6 years old, the user may set the stress threshold to 16 kg. The user has a 6 year old child weighing 18.5kg and the user sets the stress threshold to 16 kg. When children use the safety seat, even if operation button and biological information acquisition subassembly are touched to user's maloperation, because pressure that pressure sensor detection base received is greater than preset pressure threshold value, biological information acquisition subassembly can not gather and treat discernment biological information, and children's safety seat's locking mechanical system more can not the unblock, has improved children's safety seat's security, has avoided the potential safety hazard that user's maloperation unblock caused.

In some embodiments, the child safety seat may further include a first communication assembly and a second communication assembly. The first communication assembly is used for establishing Bluetooth communication connection with user equipment; the second communication component is used for carrying out one or more of 3G communication, 4G communication and 5G communication with the external device; the controller is electrically connected with the pressure sensor, the first communication assembly and the second communication assembly respectively. The controller is configured to perform the steps of:

detecting whether the pressure applied to the base is greater than a preset pressure threshold value or not; when the pressure applied to the base is larger than a preset pressure threshold value, acquiring a Bluetooth communication connection state between the first communication assembly and the user equipment; when the Bluetooth communication connection state is disconnected, first prompt information is sent to the user equipment through the second communication assembly to remind a user that children are left in the car.

The Bluetooth communication connection has the advantages of low power consumption, low time delay and good communication safety. The Bluetooth communication application of low-power consumption can reduce the burden of power supply on the child safety seat. For example, the child safety seat is powered by the detachable battery, so that the service life of the battery is longer, and the problem that the user has bad use experience due to frequent replacement of the battery by the user can be avoided; for example, the child safety seat is powered by a built-in non-detachable battery, so that the size of the battery can be reduced on the premise of enough standby time, the weight of the child safety seat is further reduced, and the use experience of a user is improved; for example, the child safety seat is powered by a cigarette lighter power supply of an automobile, so that the condition that the circuit current is overloaded due to overlarge power, and then a fuse is blown, electrical equipment is damaged, and even an automobile circuit is damaged can be avoided. The advantage of the low time delay of bluetooth communication can make children's safety seat and user equipment carry out low postpone and be connected, avoids the information lag to bring the not good application experience. The characteristic that communication security nature is good can make between children's safety seat and the user equipment not receive the influence of other communication methods, connects more stably.

In addition, the connection distance of bluetooth communication is limited, for example, the distance of a stable connection of bluetooth version 4.0 is less than 100 meters, and the distance of a stable connection of bluetooth version 5.0 is less than 300 meters, and when the distance between the user equipment and the child safety seat exceeds the distance, the bluetooth connection between the user equipment and the bluetooth safety seat is disconnected. The user equipment can be a mobile phone with a Bluetooth function, an intelligent watch, an intelligent bracelet and other equipment, and is not limited as long as the Bluetooth communication with the child safety seat can be realized. Further, the child safety seat may periodically broadcast the user identifier of the bluetooth device on the bluetooth broadcast channel, and the user device may periodically monitor the user identifier of the child safety seat on the broadcast channel, for example, ten times per minute; or the child safety seat can continuously broadcast the user identifier of the bluetooth device on the bluetooth broadcast channel, and the user device can continuously monitor the user identifier of the child safety seat on the broadcast channel.

The first prompt message may be a short message, a multimedia message, app push message or phone message transmitted to the user equipment through 3G communication, 4G communication and 5G communication. When the first message is a short message, the content of the short message can be a preset short message that 'Bluetooth is disconnected', whether the child is in a safety zone 'or' whether the child is in the safety zone 'or' you are too far away from a vehicle ', whether the child is safe' or not; when the first information is a multimedia message, the multimedia message content can be a preset picture with a prompt for paying attention to the safety of the children; when the first prompt message is a telephone, the telephone content can be a preset prompt recording, such as a prerecorded children song, so that the user can think about the condition of the children in the automobile in time; the reminding information can also be the reminding information carried by the system, such as the reminding information of 'hello host, please confirm that the little host is in the safe area', or the reminding information of 'hello host, little host has not got off the bus'; when the first prompt information is app pop-up information, the app pop-up information may be "prompt information that is set in advance, prompt information that please confirm whether children are in the security area", or information that is set by the user according to user preference. The user can be a car driver or other guardians who are in the same line with the child. In addition, the user equipment can also emit vibration or sound to prompt the user that a child is forgotten in the car.

Can detect the pressure that children's safety seat's base received through pressure sensor, here can think that, after bluetooth communication sets up, pressure sensor keeps the running state, and pressure sensor carries out pressure detection with certain periodic form to make personnel's equipment compare in real time. The period of the pressure detection of the pressure sensor can be a constant set by the system, such as one or more pressure detections per minute; the pressure detection period can be set according to the requirement of a user, for example, when a child aged 3 is used, the pressure can be detected for 10 times every 1 minute; when the pressure monitoring instrument is used by children which are older than 8 years and limit the ability of civil behaviors, the pressure detection can be set to be carried out every 10 minutes, so that the pressure monitoring instrument is more humanized, has both performance and energy consumption, and is suitable for the personalized requirements of users.

Therefore, whether the child uses the child safety seat or not is detected through the pressure sensor, the first communication assembly establishes communication connection between the child safety seat and the user equipment, and whether a user using the user equipment is far away from the automobile or not is judged according to the communication connection. When the user keeps away from the car and children use the child safety seat, the user is reminded through the second communication assembly, and the children are prevented from being forgotten in the car. Whether through being connected of user equipment and children's safety seat bluetooth on the one hand, whether accurate judgement user keeps away from the car to remind, improved the security that children took the car. On the other hand, generally speaking, the user equipment is originally provided with the bluetooth communication assembly, and the technical scheme can be implemented without modifying the user equipment or paying extra cost, so that the user equipment is favorable for popularization and wide-range use.

When the transmission mechanism is at a first position, the locking mechanism is in a locking state, and when the transmission mechanism is at a second position, the locking mechanism is in an unlocking state; alternatively, the locking mechanism may remain locked when the actuator is in the first position and may be switchable between the locked and unlocked states when the actuator is in the second position. The power mechanism is used for driving the transmission mechanism to move from the first position to the second position, or driving the transmission mechanism to move from the second position to the first position.

The controller is electrically connected with the operation button, the biological information acquisition assembly and the power mechanism, and the second type of authentication biological information is stored in the controller. Referring to fig. 4, the controller is configured to perform the steps of:

step S201, when the operation button receives a pressing operation, the biological information acquisition component is used for acquiring biological information to be identified, and the biological information to be identified is compared with the second type authentication biological information.

Step S202, when the fact that the biological information to be identified is matched with one of the second type authentication biological information is detected, an operation prohibiting instruction is sent to the power mechanism, and the transmission mechanism keeps the current position unchanged.

Step S203, when it is detected that the biometric information to be identified does not match any of the second type authentication biometric information, sending an operation permission instruction to the power mechanism, so that the power mechanism drives the transmission mechanism to move from a current position to another position according to the operation permission instruction, where the current position is one of the first position and the second position, and the another position is a position other than the current position of the first position and the second position.

The base, the backrest, the connecting assembly, the operating button, the biological information acquisition assembly, the transmission mechanism, the power mechanism and the controller in the second embodiment are consistent with the implementation modes and achieved technical effects of the base, the backrest, the connecting assembly, the operating button, the biological information acquisition assembly, the transmission mechanism and the power mechanism recorded in the first embodiment, and part of the contents are not repeated.

In a specific application, a parent drives a car with three parents, four parents and five parents to go out with a child, the child sits on the child safety seat in a locked state, and finger vein information of the child is stored in the second type authentication biological information. In the driving process of the automobile, a child presses, tears or beats the operation button and/or the biological information acquisition assembly by hands, and because the finger vein information of the child is matched with the second type authentication biological information, the locking mechanism of the child safety seat can keep a locking state, and the child safety seat is prevented from being separated from the automobile seat. Finger vein information of any one of the parents Zhang III, Li IV and Wang V is not matched with biological information of second-class authentication, any one of the parents Zhang III, Li IV and Wang V can press an operation button and acquire biological information to be identified by utilizing a biological information acquisition assembly, and the child safety seat is switched from a locking state to an unlocking state, so that the child safety seat is separated from the automobile seat.

In some embodiments, public service personnel such as school teachers, policemen, doctors, nurses, etc. may also unlock the child safety seat and timely rescue the child if the parent inadvertently forgets the child in the car.

By comparing the collected biological information to be identified, when the controller detects that the biological information to be identified is matched with the second type authentication biological information, the locking mechanism is not allowed to be switched to the unlocking state. Therefore, whether unlocking is allowed or not is determined according to the identification result of the current unlocking person, and the safety degree of the child safety seat used by the child is improved.

In some embodiments, the second type of authentication biometric information is a pre-entered biometric information of a child riding in a car. Therefore, the child safety seat cannot be unlocked when a child rides on the automobile, and the safety degree of riding of the child using the child safety seat is improved.

The controller is also configured to detect pressure applied to the base through the pressure sensor when the operation button receives a pressing operation, and when the pressure applied to the base is smaller than a preset pressure threshold value, if the operation button receives the pressing operation, the biological information to be identified is collected by the biological information collection assembly, the biological information to be identified is compared with the first type of authentication biological information, and whether the locking mechanism of the child safety seat is unlocked is controlled according to a comparison result. When the pressure that the base received is not less than preset pressure threshold value, even if operating button received the press operation, biological information collection subassembly can not gather the biological information of treating discernment yet. The method can pointedly select the biological information to be identified to be compared with the first type of authentication biological information, thereby avoiding potential safety hazards caused by misoperation and unlocking of a user and reducing the data processing pressure of the child safety seat.
