It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

In the present invention, "upper" or "lower" refers to a direction away from or toward the vehicle chassis, respectively, in the case of a safety seat placed in an operating position (i.e., the safety seat is installed in a vehicle), and, when one element is "coupled" to another element, it is considered that the two communicate with each other in a wired or wireless transmission manner and that there may be intermediate elements between the two, unless otherwise stated.

Safety seats for children, especially infants, are well known and come in a variety of forms. By way of example, for infants aged 1, especially within 9 months, the safety seat is typically a cradle type safety seat, which is typically secured to the rear seat of the vehicle in a backwards mounted manner to protect the delicate cervical spine of the infant in the event of an emergency brake or vehicle crash. Along with the baby grows up and when can sitting alone, safety seat can be changed into full cladding type safety seat, and full cladding type safety seat fixes on the vehicle back seat with the mode of dorsad installation, can provide wider field of vision for the baby of sitting alone through the vehicle side window. Of course, there are currently integrated function safety seats, such as a cradle type safety seat detachably coupled to a full wrap type safety seat, to accommodate seating needs of children in different stages of growth by a single safety seat. When an infant, in particular a newborn, is placed and restrained in a safety seat by a guardian, the infant may cry anxiously due to the missing guardian's accompany, which may also distract the guardian as a driver from when driving the vehicle, the present invention aims to reduce or even avoid the possibility of the infant crying when placed and restrained in the safety seat by providing the vehicle-mounted infant soothing device with an infant soothing function.

Referring to fig. 1, an in-vehicle infant pacifying apparatus 10 according to an embodiment of the present invention includes a safety seat. For example, the safety seat may be suitable for infants within 1 year of age (especially 9 months) and/or up to a weight of 10 kg.

The safety seat includes a seat main body including a lying portion 12 adapted to a baby to lie (e.g., half-lying or lying), and side fence portions 14 provided on both sides of the lying portion 12 and extending at an angle with respect to the lying portion 12, the lying portion 12 and the side fence portions 14 collectively defining a baby lying space. The lying portion 12 may be curved in sections to varying degrees to meet the ergonomic requirements of the infant, for example, the lying portion 12 may include an upper lying section 12A adapted to be placed on and above the back of the infant (e.g., head and neck) and a lower lying section 12B adapted to be placed below the back of the infant (e.g., buttocks, legs and feet). Optionally, the upper lying section 12A is curved upwards with an overall slope of 15 ° to 45 ° in a direction away from the lower lying section 12B. Optionally, the lower lying section 12B curves upwards with a significantly smaller overall slope in a direction away from the upper lying section 12A. Thereby, the lying part 12 forms a lying environment resembling the bending of the guardian's arms. The side dam portions 14 may extend in sections at the same or different angles relative to the recumbent portion 12 and/or different lengths to provide side impact protection on both the left and right hands of the infant when placed in the safety seat. Likewise, the side barrier portions 14 may include upper side barrier sections 14A corresponding to both sides of the upper lying section 12A of the lying portion 12 and lower side barrier sections 14B corresponding to both sides of the lower lying section 12B of the lying portion 12.

The seat body comprises a seat shell 13 and a seat soft package 15 at least partially covering the seat shell 13. The seat shell 13, which is the load-bearing structure of the safety seat, may be made of a hard plastic or a fiber composite, for example, a fiber composite including CFRP (carbon fiber reinforced matrix composite) and/or GFRP (glass fiber reinforced plastic). The seat body may be a one-piece structure having multiple portions or a multi-piece structure having multiple pieces that are joined together. The seat soft bag 15 forms, for example, the surfaces of the lying portion 12 and the side shield portions 14 facing the space where the infant lies, to increase the flexibility of the safety seat. The seat soft bag 15 may be made of a foam or other soft material. It will be appreciated that additional padding may also be placed on the lying portion 12 to further increase the flexibility of the safety seat and/or to vary the degree of curvature of the upper lying section 12A and/or the lower lying section 12B.

The seat body may also include a removable headrest 30, as shown in fig. 2 and 3, the headrest 30 having a pillow interior 32 and side wings 34 extending generally perpendicular to the pillow interior 32 or at an angle to the pillow interior 32 on either side or around the pillow interior 32, such that the headrest 30 is U-shaped, wing-shaped, or horn-shaped. The wings 34 provide additional side impact protection to the head of an infant lying in the safety seat. Alternatively, the headrest 30 may be mounted on the upper lying section 12A, for example, the pillow interior 32 may be mounted in the portion as shown by the dashed box H in fig. 1, such that the side wings 34 of the headrest 30 oppose or directly adhere to the upper side stop section 14A adjacent thereto. With the shoulder 34 adjacently opposing the upper dam section 14A, the shoulder 34 faces the upper dam section 14A and may be spaced apart from or at least partially in contact with the upper dam section 14A. The headrest 30 may be made of a foam material or other flexible material, for example, the foam material includes EPP (expanded polypropylene foam), EPS (polystyrene foam), and/or EPE (pearl wool). It is to be understood that the headrest 30 may be otherwise configured, so long as the configured headrest 30 provides additional side impact protection to the infant's head.

In an alternative embodiment, the safety seat further comprises a seat base 16, the seat body being fixedly attached above the seat base 16. The seat base 16 includes a fixing device (not shown) configured as an ISOFIX joint that can be inserted into an ISOFIX interface pre-provided in the vehicle to simply and safely place the safety seat on the rear seat of the vehicle and securely fix it in the vehicle. The safety seat can be fixed in the vehicle by means of an ISOFIX joint in a rear-mounted and/or back-mounted manner. It will be appreciated that the fixture may also be configured in other ways as deemed appropriate by those skilled in the art, for example, the fixture may also be a LATCH joint or the like. In addition, the safety seat may be provided with additional fixing fittings at other locations in addition to the seat base 16.

Additionally, the safety seat may also include a generally U-shaped handle 18. The handle 18 is configured to make the safety seat easy to carry by a person when detached from the rear seat of the vehicle. The handle 18 is pivotally connected to the seat body. The safety seat may further comprise a three-point or five-point harness configured to restrain an infant lying in the safety seat, the drawing of the harness being omitted for clarity and simplicity of illustration.

The safety seat may be devoid of a seat base 16, instead the safety seat will act as an infant carrier, being removably incorporated into another safety seat. The further safety seat itself has a child seating area for placing a child that may be seated and/or erected, and the further safety seat already has, for example, an ISOFIX joint to enable insertion of an ISOFIX interface pre-provided in the vehicle. Therefore, in order to realize a comprehensive function safety seat, when an infant cannot sit alone, an infant carrier is connected and accommodated into the child seating area of the other safety seat through a plurality of connection members for placing the infant that cannot sit alone. The infant carrier may be detachable from the further safety seat when the infant may be seated alone.

In an alternative embodiment, the in-vehicle infant calming device 10 may comprise a playing means 20, the playing means 20 being configured to play the guardian's voice and being arranged (e.g. embedded) in the upper side stop section 14A of the seat body. The voice of the guardian refers to any audio having a soothing effect on the infant, such as the guardian's singing voice, speaking voice, heartbeat voice, and so on. The number of the playing devices 20 may be two, and are respectively disposed in the upper side block sections 14A on both sides of the upper lying section 12A. Alternatively, the playback device 20 is provided in a setting portion of the upper side fence section 14A corresponding to an ear of an infant lying in the safety seat. For example, the location of the playing device 20 may be determined based on the average length of the baby and ergonomic data. For example, the average body length of a baby of 6 months old (girls for example) is 67cm, and the eye height substantially flush with the ear height is equal to 0.933 × body length according to ergonomic data, whereby the setting position of the playback apparatus 20 can be determined based on the length of the side shield portion 14 defining the lying space of the baby. Alternatively, the position is set closer to the upper lying section 12A to be closer to the ears of the lying infant in the height of the side shield portions 14 defining the infant lying space. Thus, even if a certain amount of in-vehicle noise is generated while the vehicle is traveling, the baby lying in the safety seat can easily hear the sound of the guardian who is played by the playback device 20, and the volume of the playback device 20 does not need to be adjusted to be too large.

In an alternative embodiment, as schematically illustrated in the block diagram of fig. 4, the playback device 20 comprises a memory element 201, an audio playback circuit 202, and a control element 203. The memory element 201 is configured to store audio data related to the guardian's voice. The memory element 201 includes, but is not limited to, a nonvolatile memory element such as a ROM (read only memory) and a flash memory. Optionally, the audio playback circuit 202 includes an audio input unit 202A, an audio processing unit 202B, and an audio output unit 202C, the audio input unit 202A being configured to acquire audio data from the storage element 201. The audio processing unit 202B is configured to convert the audio data into an audio signal suitable for playing by the audio output unit 202C. The audio output unit 202C is configured to play audio at a certain volume based on the audio signal, for example, a heart sound of a guardian. Optionally, the audio processing unit 202B is configured to adjust the volume of the audio, for example, such that the volume of the audio is significantly less than the maximum volume at which people play music regularly, in order to prevent damage to the eardrum of the infant. The control element 203 is coupled to the storage element 201, the audio playback circuit 202, and other various electronic devices of the playback apparatus 20 to be described below, so as to control the operation of the entire playback apparatus 20. It is understood that the playing device 20 can be powered by its own rechargeable battery (e.g., lithium battery) or other vehicle charging device. The control element 203 may be manipulated by the user, i.e. the guardian, via an additional wired or wireless control interface.

Since the structure of the playback device 20 can already realize a small or even miniature playback device 20 (e.g., including MEMS speakers, etc.), based on the volume of the playback device 20 and the thickness of the soft seat package 15, the playback device 20 can be embedded only in the soft seat package 15 without interfering with the molding of the seat shell 13, and thus with little interference with the existing safety seat manufacturing process. For example, a slot 17 for receiving the playback device 20 can be provided in the top side rail section 14A only for the seat bag 15. Therefore, the playback device 20 is easy to handle.

Since the playback devices 20 are provided in the upper side rail sections 14A at the locations corresponding to the ears of the infant lying in the safety seat, the playback devices 20 are shielded by the side wings 34 of the headrest 30, while the foam material from which the headrest 30 is made generally has a sound insulating effect due to the material properties. For this purpose, a plurality of through holes are disposed in the through hole distribution region 36 of the side wing 34 corresponding to the playing device 20, so as not to obstruct the propagation path of the guardian's voice played by the playing device 20 toward the ear of the baby. In turn, the embedded playback device 20 does not affect the protection functions of the safety seat, particularly the side impact protection of the headrest 30. The through hole distribution area 36 covers all positions of the ears and the side wings of the safety seat suitable for the baby during the whole growth process (i.e. 0 to 1 year old, or 0 to 9 months old), which can also be determined based on the average length and ergonomic data of the baby during the whole growth process as described above for the setting part of the playing device 20. Alternatively, as shown in fig. 2, the through holes have the same size and are uniformly distributed corresponding to the playing device 20. Alternatively, as shown in fig. 3, the plurality of through holes include one main through hole having a diameter corresponding to the size of the playback device 20, and a plurality of auxiliary through holes having a diameter significantly smaller around the one main through hole. It will be appreciated that the size and distribution of the plurality of through holes may be of other designs, and that the distribution of the plurality of through holes in the figures is merely illustrative and not drawn to scale.

Optionally, the playback device 20 may also include a first sound sensor 204 (e.g., including a microphone) disposed in the up-side gear section 14A. The first sound sensor 204 is configured to sense the baby's cry and send a crying signal corresponding to the baby's cry to the control element 203, and the control element 203 can turn on the audio playback circuit 202 based on the received crying signal. Alternatively or additionally, control element 203 may turn off audio playback circuit 202 based on the duration of time (e.g., exceeding a preset value) that the crying signal is received. Alternatively, the first sound sensor 204 may be disposed at a suitable portion (e.g., the top portion) of the upper side block section 14A or the upper lying section 12A and does not interfere with the audio playing circuit 202, i.e., the first sound sensor 204 cannot sense the audio played by the audio playing circuit 202, and in turn, the audio played by the audio playing circuit 202 does not affect the accuracy of the first sound sensor 204 in sensing the crying of the baby.

The playback device 20 may also include a collector 205 for collecting the guardian's voice. For example, the collector 205 is a pulse sensor, when in use, the pulse sensor is worn on the wrist, fingertip or any body part suitable for collecting the pulse of the guardian to collect the pulse wave of the guardian, then the pulse sensor sends a pulse signal related to the pulse wave of the guardian to the control element 203, the control element 203 is configured to generate audio data related to the heartbeat sound of the guardian based on the received pulse signal simulation, and the audio data is stored in the storage element 201. For example, the pulse sensor may be an infrared, piezoelectric, or resistive pulse sensor. Alternatively, in order to variously sense various sounds of the guardian, the collector 205 may be a second sound sensor (e.g., a microphone), which has a sound pickup function when in use, collects singing and/or speaking sounds of the guardian when placed near the mouth of the guardian, collects heartbeat sounds of the guardian when placed at the heart of the guardian, and transmits an audio signal related to the sounds of the guardian to the control element 203, and the control element 203 converts the audio signal into audio data and stores the audio data in the storage element 201. The audio data stored in the storage element 201 may be default audio data set by the factory. When new guardian or guardian audio data is stored in the memory element 201, the default audio data may be replaced or still exist as one of the options, and thus the user may select which piece of audio data to use through an additional wired or wireless control interface. The collector 205 is separate from the safety seat to facilitate the guardian to collect and update the audio data in the memory element 201 at any time (e.g., while holding the baby for pacification). The control component 203 is coupled to the collector 205 and can communicate via wireless transmission (e.g., using bluetooth, WiFi, NFC protocol, etc.).

Although some specific embodiments of the present invention have been described in detail by way of illustration, it should be understood by those skilled in the art that the above illustration is only for purposes of illustration and is not intended to limit the scope of the invention. It will be appreciated by those skilled in the art that modifications may be made to the above embodiments without departing from the scope and spirit of the invention.
