[0040] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Usually, the components of the embodiments of the present invention described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0041] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents the selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts fall within the scope of protection of the present invention.

[0042] It should be noted that: similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0043] In the description of the present invention, it should be noted that if terms such as "upper", "lower", "inner", "outer", etc. are used to indicate the orientation or positional relationship, it is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the present invention is usually placed when in use. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation to the present invention.

[0044] In addition, terms such as "first" and "second" are only used for distinguishing descriptions and should not be construed as indicating or implying relative importance.

[0045] It should be noted that, without conflict, the features in the embodiments of the present utility model can be combined with each other.

[0046] With the upgrading of consumers, more and more parents not only pay attention to the safety of children's car seats but also particularly care about the comfort of children when sitting in child safety seats.

[0047] For example, with the popularization of more and more new energy vehicles, and the roof design of new energy vehicles adopting panoramic sunroofs or skylight designs, especially when driving with children in the hot summer, since the hood of the child safety seat can cope with the situation of direct sunlight when children are sitting in the child safety seat, the child safety seat with a hood has become an essential choice.

[0048] The hoods of child safety seats in the prior art are often more suitable for newborns and infants. However, as children grow and reach a certain height, the hoods can no longer be used.

[0049] Specifically, the hoods of child safety seats in the prior art all adopt a fixed - type usage method for the hood, that is, the height of the hood cannot be adjusted. As the child sitting in the seat grows taller, the height of the headrest of the child safety seat will be adjusted accordingly. However, during the forward rotation process of the hood bracket, it will be interfered by the headrest. Therefore, the raised headrest will affect the normal unfolding of the hood.

[0050] In view of this, please refer to Figures 1 - 16 , the hood 200 height - adjusting mechanism and the child safety seat provided in the embodiments of the present utility model can solve this problem, and the following will describe it in detail.

[0051] Please first refer to Figure 1 and Figure 2 , an embodiment of the present utility model provides a child safety seat, which includes a seat body and a hood 200 height - adjusting mechanism. The hood mounting member 100 (detailed below) of the hood 200 height - adjusting mechanism is installed on the seat body. The hood 200 height - adjusting mechanism can realize the height adjustment of the hood 200, ensuring that the hood 200 can still be normally unfolded while the height of the headrest 1120 is adjusted.

[0052] Specifically, in this embodiment, the seat body includes a backrest 1110 and a headrest 1120. The headrest 1120 is movably mounted on the backrest 1110. For example, the headrest 1120 is slidably mounted on the backrest 1110 to facilitate adjusting the height of the headrest 1120. The sunshade 200 height adjustment mechanism includes a sunshade mounting member 100 and a sunshade 200. The sunshade mounting member 100 is used to be mounted on the seat body, and the sunshade 200 is slidably mounted on the sunshade mounting member 100 to adjust the height of the sunshade 200. Among them, the sunshade mounting member 100 is mounted on the backrest 1110 of the seat body.

[0053] After the height of the headrest 1120 of the seat body is increased, the sunshade 200 can be made to slide relative to the sunshade mounting member 100, and the height of the sunshade 200 can be adjusted accordingly, that is, the height of the sunshade 200 can also be increased to avoid interference between the unfolding process of the sunshade 200 and the headrest 1120. Therefore, this sunshade 200 height adjustment mechanism can ensure that the sunshade 200 can be normally unfolded while the height of the headrest 1120 is adjusted.

[0054] It should be noted that in this embodiment, the sunshade mounting member 100 and the backrest 1110 can be understood as separate components. In some embodiments, the sunshade mounting member 100 and the backrest 1110 can also be integrally formed.

[0055] Among them, the number of the sunshade mounting members 100 can be multiple, and the sunshade 200 is simultaneously slidably mounted on multiple sunshade mounting members 100. Here, the multiple can be at least two. For example, the number of the sunshade mounting members 100 can be two, three, four, etc.

[0056] In this embodiment, the number of the sunshade mounting members 100 is two, and the two sunshade mounting members 100 are spaced apart. The second sunshade rod 220 (detailed below) of the sunshade 200 is simultaneously slidably mounted on the two sunshade mounting members 100, and the two sunshade mounting members 100 are mounted on both sides of the backrest 1110.

[0057] It should be noted that in this embodiment, the sunshade 200 includes a sunshading member, a first sunshade rod 210, and a second sunshade rod 220. The sunshading member can be a sunshade cloth. The sunshading member is simultaneously connected to the first sunshade rod 210 and the second sunshade rod 220. The first sunshade rod 210 is rotatably connected to the second sunshade rod 220. Specifically, the first sunshade rod 210 and the second sunshade rod 220 can be connected by a pin shaft to realize the relative rotation of the first sunshade rod 210 and the second sunshade rod 220. Among them, the second sunshade rod 220 is slidably mounted on the sunshade mounting member 100.

[0058] It is easily understood that when the canopy 200 needs to be deployed, the first canopy rod 210 rotates relative to the second canopy rod 220, and then the sunshade member can be driven to deploy, so that the canopy 200 has a sunshading function.

[0059] Specifically, please refer to Figure 2 , Figure 5 and Figure 16 . In order to facilitate the sliding of the canopy 200 relative to the canopy mounting member 100, the canopy mounting member 100 has a slide rail 110, and the second canopy rod 220 of the canopy 200 is provided with a chute (not shown in the figure). The slide rail 110 and the chute are in sliding fit to facilitate adjusting the height of the canopy 200.

[0060] It should be noted that the length of the slide rail 110 can be set according to the actual situation. For example, the length of the slide rail 110 can be set according to the height of the older child sitting. The higher the height of the older child sitting, the longer the slide rail 110 can be, so that after the height of the headrest 1120 is increased, the height of the canopy 200 can be correspondingly increased to avoid interference between the deployment process of the canopy 200 and the headrest 1120.

[0061] In order to facilitate the canopy 200 to maintain its height position unchanged after being raised, the slide rail 110 of the canopy mounting member 100 has a gear block 111. The gear block 111 is used to abut against the chute of the second canopy rod 220 of the canopy 200 when the canopy 200 slides relative to the canopy mounting member 100 to a preset position, so as to limit the relative sliding between the slide rail 110 of the canopy mounting member 100 and the second canopy rod 220 and keep the height position of the canopy 200 unchanged.

[0062] This preset position can be understood as the height position where the canopy 200 is located after being raised according to the actual situation, so as to avoid interference between the deployment process of the canopy 200 and the headrest 1120.

[0063] Of course, in order to enable the canopy 200 to be maintained at multiple height positions, in this embodiment, the number of gear blocks 111 is multiple, and the multiple gear blocks 111 are spaced apart, and the height of each gear block 111 is different. For example, the number of gear blocks 111 can be two, three or four, etc.

[0064] According to a child safety seat provided by this embodiment, the working principle of the child safety seat:

[0065] As Figure 3 and Figure 4 shown, at this time, both the headrest 1120 and the canopy 200 of the child safety seat are not raised, which is equivalent to that both the headrest 1120 and the canopy 200 are in the initial state, and the canopy 200 can be normally deployed, which is applicable to children in the lower age group.

[0066] As Figure 6 and Figure 7 shown, as the child grows older, the height also increases. To accommodate older children, the headrest 1120 needs to slide relative to the backrest 1110, thereby increasing the height of the headrest 1120, and the headrest 1120 is in an elevated state.

[0067] Please continue to refer to Figure 10 and Figure 11 , to avoid interference during the deployment of the canopy 200, the height of the canopy 200 is also adjusted, and the canopy 200 is also in an elevated state. Specifically, the second canopy rod 220 of the canopy 200 slides relative to the slide rail 110 of the canopy mounting member 100, so that the height of the canopy 200 also rises. After that, the gear block 111 abuts against the second canopy rod 220, and the canopy 200 maintains its height position at this time.

[0068] Next, continue to refer to Figure 12 and Figure 13 , the first canopy rod 210 starts to rotate relative to the second canopy rod 220. Continue to refer to Figure 14 and Figure 15 , the first canopy rod 210 continues to rotate relative to the second canopy rod 220 until the canopy 200 completes the deployment action. Since the height of the canopy 200 increases, during the process of the first canopy rod 210 rotating relative to the second canopy rod 220, it will not interfere with the headrest 1120. In this way, for older children, this child safety seat can still provide a sunshade function.

[0069] In addition, it should be noted that reference can be made to Figure 8 and Figure 9 , as the child grows older, the height also increases. To accommodate older children, the headrest 1120 needs to slide relative to the backrest 1110, thereby increasing the height of the headrest 1120. However, if the height of the canopy 200 can only remain at the initial position (equivalent to the canopy in the prior art being in a fixed state and unable to adjust the height), during the process of the first canopy rod 210 of the canopy 200 rotating relative to the second canopy rod 220, it will interfere with the headrest 1120.

[0070] That is to say, in the child safety seat in the prior art, after the headrest height is adjusted, since the canopy cannot adjust the height, if the canopy is deployed, the canopy will interfere with the headrest, causing the canopy to lose its function.

[0071] In summary, the height adjustment mechanism of the canopy 200 includes a canopy mounting member 100 and a canopy 200. The canopy mounting member 100 is used to be installed on the seat body, and the canopy 200 is slidably installed on the canopy mounting member 100 to adjust the height of the canopy 200.

[0072] After the height of the headrest 1120 of the seat body is increased, the canopy 200 can be slid relative to the headrest mounting part 100, and the height of the canopy 200 can be adjusted accordingly to avoid interference between the unfolding process of the canopy 200 and the headrest 1120. Therefore, the height adjustment mechanism of the canopy 200 can ensure that the canopy 200 can still be unfolded normally when the height of the headrest 1120 is adjusted.

[0073] The child safety seat comprises a seat body and the above-mentioned head canopy 200 height adjustment mechanism, a head canopy mounting member 100 of the head canopy 200 height adjustment mechanism is mounted on the seat body, and the child safety seat has all the functions of the above-mentioned head canopy 200 height adjustment mechanism.

[0074] In addition, the child safety seat can fully utilize the function of the head canopy 200 when children of all ages are sitting in the child safety seat, that is, the height of the head canopy can be adjusted as the child grows in height, and it can be used by both older children and newborns, greatly extending the service life of the head canopy configured on the child safety seat.

[0075] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
