Description

Technical Field

[0001] This utility model belongs to the field of child car seats, and relates to a child car seat and its airbag module. Background Technology

[0002] To improve child safety while traveling in cars, child car seats are typically installed. Some child car seats are equipped with airbags. When the car is moving normally, the airbag is in a deployed state and contained within the child car seat. In the event of a collision, the airbag inflates and extends outwards from the child car seat, blocking the child's front body and preventing them from hitting the front seat. However, during a collision, due to inertia, the airbag may move forward, creating a significant distance between the child and the airbag, failing to provide adequate support and protection. To address this, some solutions integrate the airbag with the seatbelt assembly to prevent the airbag from moving excessively away from the child during a collision. However, these solutions suffer from inconvenient installation, increased costs, and in some cases, even reduced comfort of the seatbelt assembly.

[0003] The information disclosed in the background section is only intended to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0052] In this document, the terms “up,” “down,” “left,” “right,” etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings of the child car seat in normal use. They are used only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0053] Figures 1 to 15 The diagrams are drawn to scale. To keep the instructions concise, the proportions of each component are not listed individually. However, the proportions and positions of each component should be considered part of the contents of this instruction manual. Example

[0054] Reference Figures 1 to 8 As shown, this embodiment provides a child car seat 100 and an airbag module 103 for the child car seat 100. The child car seat 100 is used to install on a car seat, and a child sits in the child car seat 100, which provides safety protection for the child.

[0055] Combination Figure 1 and Figure 2 As shown, a child car seat 100 includes a body 101 and a seatbelt assembly 102. The body 101 may include a base and a seat mounted on the base. Some child car seats 100 may also include a headrest, and some may further include support legs. The seatbelt assembly 102 is used to restrain a child in the seat. The seatbelt assembly 102 includes two shoulder straps 8 and Figures 3 to 8The airbag module 103 is shown. Each shoulder seatbelt 8 is connected to a buckle connector. The airbag module 103 includes a joint, and the joint and the buckle connector cooperate to form the buckle of the seatbelt assembly. One of the joint and the buckle connector is a male connector, and the other is a female connector, and the two are detachably connected. Specifically, in the example shown in the figure, the joint is a female connector, such as a slot 2; the buckle connector is a male connector, such as a tab 81; the tab 81 is inserted into the slot 2 to lock the buckle, and the tab 81 is disengaged from the slot 2 to unlock the buckle.

[0056] Combination Figures 3 to 8 As shown, the airbag module 103 of the child car seat 100 includes a module shell and an airbag (not shown in the figure). The module shell includes a shell 1 with a hollow inner cavity, which can be a plastic injection molded part. The module shell also includes a joint provided on the shell, which is detachably connected to the buckle connector on the seat belt; the joint is preferably a slot 2, which can be detachably connected to the buckle connector (insert 81) on the shoulder seat belt 8. The airbag is made of a flexible material and can inflate after inflation. The airbag is disposed in the inner cavity of the shell 1. The airbag has a folded state and an inflated state. In the folded state, the airbag is housed in the inner cavity; in the inflated state, at least part of the airbag inflates outside the module shell. Furthermore, an airbag window 12 is provided on the shell 1 to allow the airbag to bulge out of the shell 1 after inflation, providing safety protection for the child.

[0057] The housing 1 has an inner panel 14 configured to face the child's abdomen, an outer panel 15 opposite to the inner panel 14, and a side panel connecting the inner panel 14 and the outer panel 15, with a joint provided on the inner panel 14 or the side panel. Specifically, regarding the appendix... Figures 1 to 8 In the example shown, the joint is disposed on the inner plate 14 of the housing 1. Further, the joint is formed within a slot 3, which is fixed to the inner plate 14, for example, by screws. In some other embodiments, the slot 3 and the housing 1 are integral, that is, the slot 3 and the housing 1 are a single integral part.

[0058] A groove 141 is provided on the inner side of the housing 1, and the joint is located within the groove 141. The joint includes a slot 2 for positioning the latch connector, and the slot 2 is exposed towards the groove 141. The slot 2 is disposed within the housing 1 and has a slot opening located on the side wall of the groove 141; or, the module housing also has a slot seat 3 fixed to the housing 1, the slot seat 3 is located within the groove 141, the slot 2 is disposed within the slot seat 3, the groove 141 has a bottom wall and a side wall, the bottom wall and the opening of the groove 141 are opposite each other, and the opening of the slot 2 is disposed on the side wall of the groove 141. Specifically, in this embodiment, as Figure 4 and Figure 5As shown, the joint includes a slot 2 formed on the slot base 3, the slot 2 having an upward-facing notch. The slot base 3 has two slots 2 arranged side-by-side, and the inserts 81 on the two shoulder straps 8 are correspondingly inserted into the two slots 2. Further, a groove 141 is formed on the inner plate 14, the groove 141 being located above the slot 2 and communicating with the notch of the slot 2, for accommodating the insert 81 and providing operating space for inserting the insert 81 downwards into the groove 141.

[0059] like Figure 8 As shown, the housing 1 has an outer housing 1a and an inner housing 1b that are joined together, with an inner cavity located between the inner housing 1b and the outer housing 1a. A groove 141 is formed by a portion of the inner housing 1b recessed towards the outer housing 1a. The depth of the groove 141 is adapted to the snap fastener so that, after the snap fastener is engaged with the joint, the snap fastener does not protrude from the opening of the groove 141.

[0060] The airbag module 103 also includes an unlocking member 4 for disengaging the first buckle connector (slot 2) from the buckle connector (insert 81). The unlocking member 4 is disposed on the module housing 1. Specifically, the unlocking member 4 is movably disposed on the outer plate 15. Operating the unlocking member 4 allows the insert 81 to disengage from the slot 2, thereby unlocking the buckle. The locking and unlocking structure of the buckle is not a key aspect of this invention; existing locking and unlocking structures for child car seat buckles can be used and will not be elaborated upon here.

[0061] The airbag module 103 also includes a lap belt 7, the lower end of which is connected to the body 101 of the child car seat 100, for example, by fitting it onto a connecting shaft 82 on the body 101 of the child car seat 100, thereby securing the lap belt 7 to the body 101. The upper end of the lap belt 7 is connected to the module housing.

[0062] like Figure 8As shown, a gas cylinder 6 is disposed within the inner cavity of the housing 1. The gas cylinder 6 is connected to an air bladder to supply air to the air bladder. Specifically, the inflation port of the air bladder is fitted onto the opening at the top of the gas cylinder 6. When needed, air from the gas cylinder 6 enters the air bladder, causing it to inflate. The inner cavity of the housing 1 includes an air bladder receiving chamber 11 located above the gas cylinder 6, within which the air bladder is placed in a contracted state. The air bladder receiving chamber 11 is preferably located at the top of the inner cavity, and an air bladder window 12 is disposed at the top of the housing 1, with a sealing cover 13 on the air bladder window 12. Under normal conditions, the airbag is in a contracted state within the airbag housing 11, and the gas cylinder 6 does not inflate the airbag. When a collision occurs, the gas cylinder 6 supplies air to the airbag, and the airbag gradually inflates. When it inflates to a certain extent (for example, the airbag fills the airbag housing 11), the sealing cover 13 is pushed out by the airbag, thus detaching from the airbag window 12. The airbag further inflates and bulges upward from the airbag window 12, providing cushioning for the child. Typically, the inflated airbag is positioned between the child and the front seat to prevent the child from colliding with the front seat. The airbag inflation structure and control logic are not the focus of this invention; they can employ airbag inflation mechanisms and control logic known in the prior art, and will not be elaborated upon here.

[0063] The safety protection principle of the airbag module 103 and the child car seat 100 in this embodiment is as follows: When the child sits in the seat, the inserts 81 on the two shoulder seat belts 8 are inserted downwards into the slots 2 of the airbag module 103 to restrain the child in the seat; when an impact occurs, in response to the inflation command issued by the vehicle control system, the airbag inflates and expands upwards towards the airbag module 103. The expanded airbag is located between the child and the front seat to prevent the child from colliding with the front seat.

[0064] The process of assembling the airbag module 103 onto the body 101 of the child car seat 100 in this embodiment is as follows: simply connect the lower end of the lap belt 7 to the body 101; specifically, the lap belt 7 can be threaded onto the connecting shaft 82 at the lower part of the body 101. The airbag module 103 as a whole can rotate around the connecting shaft 82 for convenient use.

[0065] In summary, the airbag module 103 of this embodiment has the following advantages: the airbag module 103 is integrated into the seat belt assembly 102 of the child car seat 100, especially the slot seat 3 and the slot 2 forming the buckle are integrated into the airbag module 103; if the car collides, the airbag inflates and bulges out from the airbag window 12 of the module shell 1 and remains connected to the seat belt assembly 102, so that the airbag will not move too far away from the child due to inertia, thus ensuring good protection for the child. Under this premise, the assembly is relatively convenient (only the crotch seat belt 7 needs to be connected to the module shell 1 and the body 101 of the child car seat 100), avoiding excessive cost increase. The airbag module 103 is located on the outside of the slot seat 3, avoiding pressure on the child's chest and abdomen, and will not affect the comfort of the seat belt assembly 102. Example

[0066] This embodiment provides a child car seat 100. The only difference between the child car seat 100 in this embodiment and the child car seat 100 in embodiment 1 is the airbag module 103. Specifically, the structure of the shell 1 and the buckle seat 3 is different from that in embodiment 1. The rest is basically the same as in embodiment 1.

[0067] Reference Figures 9 to 15 As shown, the housing 1 includes a main body 1c and lateral extensions 1d disposed on the left and right sides of the main body 1c, with joints located on the lateral extensions 1d. The main body 1c includes an upper body 1c1 and a lower support 1c2, with the lower support 1c2 located below the upper body 1c1 and used for engaging with a car seat. An inner cavity is disposed in the upper body 1c1, and the lateral extensions 1d are located on the left and right sides of the lower support 1c2. The joints include slots 2 disposed on the lateral extensions 1d, with slot openings facing upwards. Each of the left and right lateral extensions 1d has a joint, i.e., each lateral extension 1d has a slot 2, with the slot openings facing upwards, for connection with the buckle connectors (inserts 81) on the left and right shoulder seat belts 8, respectively.

[0068] The bottom of the lower support 1c2 is provided with a rotating connecting part 16, which is configured to be rotatably connected to the body 101 of the child car seat 100. Specifically, the airbag module 103 and the body 101 of the child car seat 100 can be assembled by passing a connecting shaft 82 through the rotating connecting part 16 and the body 101 of the child car seat 100. The airbag module 103 can rotate around the connecting shaft 82 for convenient use.

[0069] The airbag window 12 is open. The airbag window 12 is located at the top of the housing 1, and the airbag can bulge upward from the airbag window 12 after inflation.

[0070] In this embodiment, after the airbag of the airbag module 103 inflates, it can remain connected to the seat belt assembly 102, ensuring good protection for the child. The assembly is relatively convenient and avoids excessive cost increase. The airbag module 103 is located between the slots 2 on both sides, avoiding pressure on the child's chest and abdomen and not affecting the comfort of the seat belt assembly 102.
