[0029] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and do not necessarily describe a specific order or sequence.

[0030] The terms "include" and "have" and any variations thereof in the specification and claims of the present application are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device that includes a series of steps or units does not have to be limited to only those steps or units clearly listed, but can include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0031] The present application will be further described below in conjunction with the drawings:

[0032] As shown in Figures 1 to 8 The present application provides a neck protection mechanism, which comprises a base 11 and a supporting body 12, one side of the base 11 is connected with the supporting body 12, and the other side of the base 11 is adapted to be connected and fixed with a mounting position provided on a seat and located at least one side of the head and neck position, and the supporting body 12 is adapted to contact and support the head and neck of the human body.

[0033] The neck protection mechanism 1 can be directly installed as an expansion module on an existing seat. In the field of existing seats, especially safety seats 2, both sides of the head and neck position often have structural designs. The neck protection mechanism 1 of the present application can use the base 11 to be connected and fixed to the structure, so that the supporting body 12 can cooperate with the seat to expand the supporting structure, thereby protecting the head and neck of the human body, having high applicability, reducing or even eliminating the need to modify the original structure of the seat.

[0034] For example, when the head and neck position of the safety seat 2 has a hollow structure design on both sides, and a guide hook 22 is arranged at the hollow structure design, the base 11 can be designed to be combined with the guide hook 22 to realize the connection and fixation of the neck protection mechanism 1.

[0035] Alternatively, when the head and neck position of the safety seat 2 has a hollow structure design on both sides, and other structures are arranged at the hollow structure design, the structure of the base 11 is correspondingly modified and designed to be combined with the structures to realize the connection and fixation of the neck protection mechanism 1.

[0036] Even, the head and neck position of the safety seat 2 is designed with a protruding structure on both sides, and the base 11 can also be designed to be combined with the protruding structure to realize the connection and fixation of the neck protection mechanism 1.

[0037] Specifically, for the case that the head and neck position of the safety seat 2 has a hollow structure design on both sides, the base 11 is provided with a connecting portion 111, at least one protruding buckle 1111 is arranged on the end of the connecting portion 111 away from the supporting body 12, a fixing portion 112 is formed on the end of the connecting portion 111 close to the supporting body 12, the connecting portion 111 is adapted to be inserted into the installation position, and in the plane perpendicular to the direction of the insertion of the connecting portion 111 into the installation position, at least part of the projection of the fixing portion 112 and / or the supporting body 12 and the projection of the protruding buckle 1111 protrude from the projection of the connecting portion 111, the protruding buckle 1111 is adapted to be connected with one side of the installation position, and the fixing portion 112 and / or the supporting body 12 is adapted to be connected with the other side of the installation position. The design of the protruding buckle 1111 can effectively reduce the difficulty of inserting the connecting portion 111 into the installation position, thereby facilitating the quick fixation of the fixing portion 112 and / or the supporting body 12, the fixing portion 112 and / or the supporting body 12 as part of the fixing structure can reduce the complexity of the structure, reduce the difficulty and cost of production and processing, improve the compactness of the structure, and better fit the installation position.

[0038] It can be understood that the protruding buckle 1111 and the fixing portion 112 and / or the supporting body 12 can be connected with the two sides of the installation position at both ends of the connecting portion 111, thereby realizing the fixation of the neck protection mechanism 1. This fixation method is convenient to disassemble and assemble without the need for tools, is convenient for users to operate, and has higher installation stability.

[0039] As shown in the embodiment of Figure 1 The outer surface of the protruding buckle 1111 is designed as a circular arc, which can play a guiding role and further reduce the difficulty of fixing the connecting portion 111 inserted into the installation position.

[0040] As shown in the embodiment of Figures 1 to 4In the shown embodiment, the number of the convex buckles 1111 is multiple, the convex buckles 1111 are arranged at the end of the connecting part 111, and the convex buckles 1111 are distributed on the opposite first side and second side of the connecting part 111, so that the end of the connecting part 111 can be fixed to the opposite first side and second side through the convex buckles 1111, thereby improving the stability of the clamping of the connecting part 111 and reducing the probability of shaking or disengaging from the mounting position of the connecting part 111.

[0041] In some embodiments, the outer layer or the whole of the supporting body 12 is a soft package structure, and in use, the user is adapted to directly contact the supporting body 12, and the supporting body 12 can play a buffering and damping protection role.

[0042] In some embodiments, the soft package structure of the supporting body 12 can be made of flexible materials such as cotton, sponge, rubber, and silica gel, alone or in combination.

[0043] In some embodiments, in a plane perpendicular to the direction of inserting the connecting part 111 into the mounting position, the edge of the projection of the supporting body 12 is flush with or protrudes from the edge of the projection of the base 11, so that after the mounting and fixing of the neck protection mechanism 1 are completed, the periphery of the supporting body 12 can be flush with or protrude from the edge of the base 11, thereby playing a covering effect on the base 11, reducing the contact between the user and the base 11, and combining the soft package design of the outer layer or the whole of the supporting body 12, the comfort can be effectively improved.

[0044] In some embodiments, the connecting mode between the supporting body 12 and the base 11 is glue connection or insert connection or encapsulation connection, which is convenient to process, has various connection modes, can realize covering combination or contact combination, has good fixing effect, and is not easy to separate and fall off.

[0045] As Figures 2 to 8 shown, the application also provides a safety seat including a headrest assembly 21 and a guide hook 22, and the headrest assembly 21 and the guide hook 22 are adapted to form a mounting channel 23, the mounting channel 23 is adapted to connect the neck protection mechanism 1 of any of the above embodiments, the installation and fixation of the neck protection mechanism 1 are realized by using the guide hook 22 originally possessed by the safety seat 2, the structural complexity, the production and design cost, and the installation difficulty of the neck protection mechanism 1 can be reduced, the functionality and expandability of the safety seat 2 are improved, and the safety seat 2 with the guide hook 22 that has been sold on the market can also be adapted to a certain extent, and the universality of the neck protection mechanism 1 is improved.

[0046] In some embodiments, the guide hooks 22 are arranged below the headrest assembly 21, and the guide hooks 22 are generally used for guiding and fixing the safety belt in the prior art.

[0047] In some embodiments, the number of the protruding buckles 1111 is multiple, and the protruding buckles 1111 are distributed on at least two sides of the connecting part 111 away from the supporting body 12, the connecting part 111 is adapted to pass through the installation channel 23, and the protruding buckles 1111 are adapted to be clamped and matched with the headrest assembly 21 and the guide hook 22 on the other side of the installation channel 23. By using multiple protruding buckles 1111 and clamping and matching with the headrest assembly 21 and the guide hook 22 respectively, the fixing strength of the neck protection mechanism 1 can be effectively improved, the connection stability can be improved, and the shaking can be reduced.

[0048] As shown in the embodiments of Figure 2 , the connecting part 111 enters the installation channel 23 along the length direction, and the cross-sectional shape of the connecting part 111 is adapted to the cross-sectional shape of the installation channel 23, so that the connecting part 111 can also cooperate with the structure around the installation channel 23 to achieve a certain fixing effect, thereby reducing the probability of loosening and shaking of the neck protection mechanism 1.

[0049] As shown in the embodiments of Figure 3 and 4 , the connecting part 111 is provided with protruding buckles 1111 on the opposite first side and second side, the first side is adapted to be in contact with the headrest assembly 21, and the second side is adapted to be in contact with the guide hook 22. It can be understood that the headrest assembly 21 and the guide hook 22 have at least partially opposite structures at the installation channel 23, and are adapted to cooperate with the protruding buckles 1111 on the first side and the second side respectively, which can further improve the connection stability and reduce the shaking.

[0050] Specifically, the distance between the first side and the second side is not greater than the height of the installation channel 23, and the distance between the projections of the protruding buckles 1111 on the first side and the protruding buckles 1111 on the second side in the vertical plane is not less than the height of the installation channel 23, so that the protruding buckles 1111 are not easy to come out of the installation channel 23 after entering the installation channel 23, thereby improving the fixing effect of the connection.

[0051] In some embodiments, the connecting part 111 is provided with multiple protruding buckles 1111 arranged at intervals in the direction of inserting into the installation channel 23. By changing the depth of the connecting part 111 inserted into the installation channel 23, the adjustment of the neck protection position of the neck protection mechanism 1 can be realized, so that the neck protection mechanism 1 can better fit the head and neck of the child, and the supporting and protection effect can be improved.

[0052] In some embodiments, at least part of the guide hook 22 is configured as a deformation part, which is adapted to deform to increase the caliber of the installation channel 23. The structural strength of at least part of the guide hook 22 can be configured to be lower than that of the headrest assembly 21, so that at least part of the guide hook 22 can deform before the headrest assembly 21, thereby expanding the caliber of the installation channel 23 to facilitate the passage of the protruding buckle 1111 through the installation channel 23. The caliber of the installation channel 23 includes the width and height of the installation channel 23.

[0053] As shown in the embodiments of Figure 3 and 4 , the headrest assembly 21 and / or the guide hook 22 is provided with an inclined guide side 24 at the installation channel 23. The connecting part 111 and the protruding buckle 1111 are adapted to enter the installation channel 23 along the guide side 24, which can guide the protruding buckle 1111 into the installation channel 23 and then press the guide hook 22 to deform.

[0054] As shown in the embodiments of Figures 5 to 8 , the number of guide hooks 22 and neck protection mechanisms 1 is two. The two guide hooks 22 are symmetrically arranged on both sides of the headrest assembly 21 and form installation channels 23, respectively. The neck protection mechanism 1 and the installation channel 23 are connected one by one to be symmetrically fixed on both sides of the headrest assembly 21, thereby achieving the support and limitation of the head and neck of the child on both sides.

[0055] As shown in the embodiments of Figures 7 to 8 , the two symmetrical neck protection mechanisms 1 can form an outwardly expanding structure, thereby supporting and limiting the head and neck of the child on both sides while reducing the difficulty of the child leaning between the two neck protection mechanisms 1 and reducing structural interference.

[0056] As shown in the embodiments of Figure 6 and 8 , when the neck protection mechanism 1 is connected with the installation channel 23, the supporting body 12 is adapted to be attached to the headrest assembly 21 and the guide hook 22, thereby reducing the probability of the base 11 being exposed to the outside and contacting the child, improving comfort, and improving the stability of the supporting body 12 on the safety seat 2.

[0057] In some embodiments, the end of the guide hook 22 is provided with a barb part 221. When the neck protection mechanism 1 is connected with the installation channel 23, the neck protection mechanism 1 and the barb part 221 are adapted to cooperate to form a safety belt passing opening, thereby ensuring that when the neck protection mechanism 1 is installed at the guide hook 22, the guide hook 22 can still play the role of collecting, guiding and fixing the safety belt, without affecting the original function of the guide hook 22, thereby improving the functionality and expandability of the safety seat 2.
