[0041] In order to more clearly illustrate the technical solutions in the embodiments of the present application or related technologies, the following will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0042] With the continuous development of society, more and more families have their own cars, and there are more and more opportunities for children to travel with their parents. Since children have weaker self-protection ability, they often suffer greater injuries than adults in car accidents. In response to this situation, various car safety seats have appeared on the market. These safety seats can be used on ordinary car seats. If the relative fixation between the safety seat and the car seat is insufficient, then when the car is impacted, the safety seat will have a large vertical displacement under the action of inertia, which can easily cause the child's head to be hit. Because the child's body has not yet fully developed, the child's head is very fragile, so it is easy for the child's head to be seriously injured due to the impact of the car.

[0043] Regarding the above situation, first of all, please refer to Figure 1-Figure 3 The present application proposes a seat assembly 1 , comprising a seat body 10 and an anti-slip member 20 .

[0044] The seat body 10 includes a seating portion 11, a rear cover 12 and two side panels 13. The seating portion 11 is connected to the rear cover 12 and the side panels 13. The two side panels 13 are arranged on opposite sides of the rear cover 12. A seating space 14 for accommodating a user is formed between the seating portion 11, the side panels 13 and the rear cover 12. When the user is in the seating space 14, the user sits on the seating portion 11, the user's back contacts part of the rear cover 12 of the seat assembly 1, and the side of the user's body (such as shoulders, arms, etc.) contacts the side panels 13 of the seat assembly 1.

[0045] The anti-slip member 20 is located on the side of the rear cover 12 away from the seating space 14 and connected to the rear cover 12. The anti-slip member 20 is used to contact the backrest portion of the car seat, and the projection area of ​​the anti-slip member 20 on the rear cover 12 accounts for 8% to 30% of the area of ​​the side of the rear cover 12 away from the seating space 14. The anti-slip member 20 can be a silicone strip or a rubber strip to improve friction and buffering performance.

[0046] It should be noted that, in the embodiment of the present application, an anti-slip member 20 is provided on the rear cover 12 of the seat assembly 1, so that the seat assembly 1 contacts or abuts against the car seat through the anti-slip member 20, thereby increasing the friction between the seat assembly 1 and the car seat. When the car is subjected to impact force, the displacement of the seat assembly 1 relative to the car seat can be improved. At the same time, the projection area of ​​the anti-slip member 20 on the rear cover 12 accounts for 8% to 30% of the area of ​​the side of the rear cover 12 away from the seating space 14. On the basis of ensuring the production cost, sufficient friction can be provided between the seat assembly 1 and the car seat. If the ratio of the projection area of ​​the anti-slip member 20 on the rear cover 12 to the area of ​​the side of the rear cover 12 away from the seating space 14 is less than 8%, the friction between the seat assembly 1 and the car seat is insufficient, and the displacement of the seat assembly 1 relative to the car seat cannot be reduced. If the ratio of the projection area of ​​the anti-slip member 20 on the rear cover 12 to the area of ​​the side of the rear cover 12 away from the seating space 14 is greater than 30%, the production cost cannot be reduced.

[0047] See also Figure 2-Figure 3 In some embodiments of the present application, a plurality of protrusions 21 are provided on the side of the anti-slip member 20 facing away from the rear cover 12, and the protrusions 21 are used to contact the car seat to increase the friction between the anti-slip member 20 and the car seat. The plurality of protrusions 21 may be arranged in a rectangular array or in an irregular pattern, which is not specifically limited here.

[0048] Please continue to see Figure 2-Figure 4 In some embodiments of the present application, a protrusion 121 is provided on the side of the rear cover 12 away from the riding space 14, and the anti-slip part 20 is provided on the protrusion 121 to facilitate a closer contact with the car seat. The distance from the center of the protrusion 121 to the top of the rear cover 12 is D, and the height of the rear cover 12 is H, wherein the ratio of D / H satisfies 1 / 8≤D / H≤1 / 3, that is, the anti-slip part 20 is provided at the upper end of the rear cover 12. At this time, the anti-slip part 20 contacts the upper end of the car seat. When the car is subjected to impact force, the friction between the upper end of the seat assembly 1 and the upper end of the car seat is increased, thereby preventing the lower part of the seat assembly 1 from being displaced relative to the car seat, thereby better improving the situation where the seat assembly 1 as a whole is displaced relative to the car seat.

[0049] Specifically, the rear cover 12 is provided with a mounting piece for installing a safety belt, and the side of the raised portion 121 facing the riding space 14 has a mounting cavity, and the mounting piece can be inserted into the mounting cavity, that is, the mounting piece and the anti-slip piece 20 are respectively located on opposite sides of the raised portion 121, and the inner concave part of the raised portion 121 forms the mounting cavity to provide an installation space for the mounting piece, and the outer convex part of the raised portion 121 is used to set the anti-slip piece 20, reduce the distance between the anti-slip piece 20 and the car seat, so that the anti-slip piece 20 is in close contact with the car seat. The safety belt is connected to the mounting piece, and then the safety belt can extend into the riding space to fix the user's body.

[0050] See also Figure 1 In some embodiments of the present application, the seat assembly 1 also includes a first buffer assembly 30, the first buffer assembly 30 includes a first buffer layer 31 and a second buffer layer 32, the first buffer layer 31 is connected to the seat body 10, and the second buffer layer 32 is connected to the first buffer layer 31.

[0051] It is understandable that when the car is subjected to external impact, the user's body and the first buffer component 30 are squeezed, thereby prolonging the transmission time of the impact force, and the first buffer component 30 can absorb a certain amount of energy brought by the impact, reduce the acceleration of the user's body, and reduce the damage to the user's body caused by the impact force, thereby effectively protecting the user. Among them, the preparation material of the first buffer component 30 can be soft plastic, foam material or sponge, etc., to improve the protection of the first buffer component 30 to the user; the first buffer layer 31 and the seat body 10 can be connected by bonding, clamping or injection molding, etc., and the present application does not specifically limit the shape, size, etc. of the first buffer component 30.

[0052] It should be noted that one of the first buffer layer 31 and the second buffer layer 32 can be made of foamed plastic, such as polypropylene foamed plastic (EPP), polystyrene foamed plastic (EPS) or a mixture of polystyrene and polyethylene foamed plastic (EPO), etc.; the other of the first buffer layer 31 and the second buffer layer 32 can be made of sponge material, such as inert sponge or ordinary sponge, etc. Both foamed plastic and sponge have the characteristics of light weight, heat insulation, sound absorption, shock absorption, etc., so foamed plastic and sponge are applied to the first buffer component 30, which can play a good role in buffering and shock absorption, thereby reducing the impact force on the user.

[0053] For further information, see Figure 1 and Figure 5In some embodiments of the present application, a first buffer layer 31 is disposed on the side of the side panel 13 facing the seating space 14, a mounting groove 311 is provided on the side of the first buffer layer 31 facing the seating space 14, a second buffer layer 32 is disposed in the mounting groove 311, and the buffer assembly 30 on the side panel 13 can be used to protect the side of the user's body.

[0054] It can be understood that the first buffer layer 31 is made of foamed plastic and the second buffer layer 32 is made of inert sponge. Since the hardness of foamed plastic is higher than that of inert sponge, the first buffer layer 31 is easier to form and has a certain strength, so it can be better arranged on the side panel 13.

[0055] Among them, the thickness of the second buffer layer 32 along the direction perpendicular to the side panel 13 is not less than the groove depth of the installation groove 311. When the second buffer layer 32 is arranged in the installation groove 311, when the thickness of the second buffer layer 32 is relatively large, part of the second buffer layer 32 protrudes out of the installation groove 311. When the car is subjected to external impact, the side of the user's body will first contact the second buffer layer 32, and after squeezing the second buffer layer 32, it will contact the first buffer layer 31, thereby allowing the second buffer layer 32 to first absorb a certain amount of energy brought by the impact through deformation, reduce the acceleration of the body, and finally contact the first buffer layer 31.

[0056] See also Figure 1 and Figure 6 In some embodiments of the present application, the seat assembly 1 also includes a headrest 15 and a second buffer assembly 60. The headrest 15 is arranged on the side of the rear cover 12 facing the riding space 14. The second buffer assembly 60 includes a third buffer layer 61 and a fourth buffer layer 62. The third buffer layer 61 is bonded to the headrest 15, and the fourth buffer layer 62 is bonded to the third buffer layer 61. The second buffer assembly 60 on the headrest 15 can be used to protect the user's head.

[0057] Specifically, a placement groove for installing the second buffer component 60 is provided on the headrest portion 15. Exemplarily, there are two placement grooves, which are arranged opposite to each other, and each placement groove is provided with a second buffer component 60. That is to say, when the user sits on the seat component 1, the two second buffer components 60 are respectively located on the left and right sides of the user's head; or, the placement groove is extended along the circumferential side of the headrest portion 15, and the second buffer component 60 extends along the extension direction of the placement groove. That is to say, when the user sits on the seat component 1, the second buffer component 60 wraps the left, back and right sides of the user's head to better protect the user's head.

[0058] Among them, the third buffer layer 61 is made of a slow-rebound inert sponge, and the fourth buffer layer 62 is made of foamed plastic. The fourth buffer layer 62 is closer to the user's head. When the user is riding, the head can lean on the fourth buffer layer 62 at any time, so the fourth buffer layer 62 is made of foamed plastic, so that the strength of the fourth buffer layer 62 is greater than that of the third buffer layer 61, thereby reducing damage to the fourth buffer layer 62 and extending the service life of the second buffer component 60.

[0059] In some embodiments, the headrest 15 is movably connected to the back cover 12, and the headrest 15 can move relative to the back cover 12. Exemplarily, the headrest 15 is slidably connected to the back cover 12 along the height direction of the seat assembly 1, so that the height of the headrest 15 can be adjusted according to the different heights of users, thereby adapting to the head positions of different users, thereby increasing the practicality of the seat assembly 1.

[0060] Further, in some embodiments of the present application, Figure 6 As shown, a first gap L1 is provided between the second buffer component 60 and the headrest portion 15, and the first gap L1 is also an installation gap reserved for the second buffer component 60. The setting of the first gap L1 can reduce the noise generated by friction between the second buffer component 60 and the headrest portion 15, and when the second buffer component 60 is impacted by external force, the first gap L1 can provide a deformation space for the second buffer component 60, so that the second buffer component 60 absorbs the impact force through deformation to improve the buffering performance.

[0061] Among them, the value range of the first gap L1 is 6mm to 12mm, and the first gap L1 is preferably 9mm. If the first gap L1 is less than 6mm, when the second buffer component 60 is impacted by external force, the second buffer component 60 is prone to friction with the headrest portion 15 and generate noise; if the first gap L1 is greater than 12mm, the distance between the second buffer component 60 and the headrest portion 15 is too large, and the headrest portion 15 does not provide sufficient support for the second buffer component 60, which can easily lead to an unstable position of the second buffer component 60, which is not conducive to the deformation of the second buffer component 60.

[0062] For further information, see Figure 7 In some embodiments of the present application, the headrest portion 15 includes a fixing tube 151, which is connected to the rear cover 12, and the seat assembly 1 also includes a plastic adjustment member 40, which is sleeved on the fixing tube 151 to improve the connection strength between the plastic adjustment member 40 and the fixing tube 151. Specifically, a through hole 41 is provided on the plastic adjustment member 40, and the seat assembly 1 includes a safety belt, which passes through the through hole 41 to fix the safety belt.

[0063] See also Figure 8-Figure 11In some embodiments of the present application, a fixed groove 131 is provided on the side panel 13; the seat assembly 1 also includes a fixed seat 51 and an anti-collision member 52, at least a portion of the fixed seat 51 is located in the fixed groove 131, and is detachably connected to the bottom wall of the fixed groove 131 to facilitate the disassembly and replacement of the fixed seat 51 and the anti-collision member 52, and the anti-collision member 52 is provided on the fixed seat 51.

[0064] It can be understood that the setting of the fixed groove body 131 provides installation space and setting basis for the fixed seat 51 and the anti-collision member 52, and the fixed groove body 131 can limit the fixed seat 51, thereby preventing the fixed seat 51 and the anti-collision member 52 from shifting, wherein the anti-collision member 52 can be used to abut against the door of the car, and the anti-collision member 52 can be made of soft plastic, foam material or sponge and other materials to enhance the buffering effect between the seat assembly 1 and the door.

[0065] For further information, please see Figure 8-Figure 11 A mounting column 511 is provided on one of the fixing seat 51 and the fixing slot body 131, and a mounting hole 132 is provided on the other of the fixing seat 51 and the fixing slot body 131. The mounting column 511 passes through the mounting hole 132 and can be inserted into the mounting hole 132 by a bolt, so that the fixing seat 51 and the fixing slot body 131 can be detachably connected.

[0066] The peripheral side of the mounting hole 132 may be rounded to facilitate the insertion of the mounting post 511 into the mounting hole 132. Figure 10-11 As shown, the fixed seat 51 includes a first part 512 and a second part 513 connected to each other. The first part 512 extends into the fixed groove body 131, and the second part 513 is located outside the fixed groove body 131. After the first part 512 is installed in the fixed groove body 131, there is a second gap L2 between the second part 513 and the side panel 13 of the seat assembly 1. The value range of the second gap L2 is 3mm to 5mm. When a seat cloth is set on the seat assembly 1, the seat cloth can be laid from the second gap L2 to between the side panel 13 and the second part 513 of the fixed seat 51. The setting of the second gap L2 is conducive to the assembly of the seat cloth, and the second gap L2 is preferably 3mm.

[0067] See also Fig. 9 In some embodiments of the present application, a flange structure 133 is provided on the peripheral side of the side panel 13, and a reinforcing rib 134 is also provided on the side panel 13. The reinforcing rib 134 connects the groove side wall of the fixed groove body 131 and the flange structure 133 to increase the strength of the side panel 13 and the fixed groove body 131.

[0068] Second, as Figure 1-Figure 2As shown, the present application also proposes a safety seat 2, comprising a base 70 and a seat assembly 1 as described in any of the above embodiments, wherein the seat assembly 1 is disposed on the base 70 and movably connected to the base 70.

[0069] It can be understood that the seat assembly 1 can be rotatably connected to the base 70 so that the rotation angle of the seat assembly 1 relative to the base 70 can be adjusted according to the needs of different users, that is, when the user sits on the safety seat 2, the user can face the front of the car, or the user can face the rear of the car; or, the seat assembly 1 can be slidably connected to the base 70 so that the inclination angle of the seat assembly 1 can be adjusted according to the needs of different users, that is, when the user sits on the safety seat 2, the user can adjust the angle of the user's back.
