[0002] In the related technical field, car child safety seats, also known as child restraint systems (CRS), are seats specifically designed for children of different ages (or weights), installed in cars, and effectively improve children's safety while traveling. In the event of a collision or sudden deceleration, they reduce the impact force on children and restrict their body movement to minimize injury and ensure their safety while traveling.

[0003] However, the side covers of traditional car child safety seats require many bolts to be fixed, and the side covers are composed of multiple separate parts, making the structure of the side covers complex and difficult to disassemble and assemble. Summary of the Invention

[0004] This application provides a child safety seat that reduces the number of fixing points, simplifies the overall structure of the side cover, and improves the efficiency of side cover assembly and disassembly while ensuring the stability of the connection between the side cover and the seat body.

[0005] In a first aspect, embodiments of this application provide a child safety seat, the child safety seat including a seat body and a side cover installed on the side of the seat body, the seat body including an angled seat surface and a backrest; The side cover includes a backrest, side wings, a seat, and a crotch area. The backrest is installed on one side of the backrest, and a first fixing position is provided at the top of the backrest. The side wings are curved, and their two ends are respectively connected to the top and bottom of the backrest. Up to four second fixing positions are provided sequentially from one end of the side wings to the other end. There is a gap between the side wings and the backrest. The seat is connected to the backrest and installed on one side of the seat surface. The crotch area is connected to the seat, and up to four third fixing positions are provided on the crotch area. The side cover is fixedly connected to the seat body at the first fixing position, the second fixing position, and the third fixing position.

[0006] In some embodiments, the crotch portion extends upward toward the seat surface to form a half armrest, the half armrest having two spaced-apart third fixing positions; The crotch portion extends downward toward the seat surface to form a fixing plate, and the fixing plate is provided with the third fixing position.

[0007] In some embodiments, the side wing portion is an arc-shaped structure, and the arc-shaped structure is provided with three second fixing positions, which are evenly arranged along the arc-shaped extension direction.

[0008] In some embodiments, two side covers are provided, with the side covers respectively provided on opposite sides of the seat body.

[0009] In some embodiments, the first fixing position, the second fixing position, and the third fixing position are fixing holes, and the side cover is connected to the seat body by a fastener passing through the fixing hole.

[0010] In some embodiments, the fixing holes are provided with a first reinforcing structure on the side of the side cover near the seat body.

[0011] In some embodiments, the backrest portion of the side cover abuts against the seat body, and a second reinforcing structure is provided on the side of the side cover near the seat body.

[0013] In some embodiments, the avoidance structure is an avoidance notch on the third reinforcing structure, and the avoidance notch is adapted to the corresponding part of the backrest.

[0014] In some embodiments, the total number of the three types of fixed bits is 7, wherein the number of the first fixed bit is 1, the number of the second fixed bit is 3, and the number of the third fixed bit is 3.

[0015] Based on the embodiments described above, the backrest can close one side of the backrest, and the backrest can be fixed to the backrest via a first fixing point at the top; the side wings can provide some protection on the sides of the backrest, reducing the possibility of the child seat detaching from the side. After the two ends of the side wings are connected to the top and bottom of the backrest respectively, the curved side wings can create a gap between the side wings and the backrest, allowing the seat belt to pass through this gap, thereby increasing the range of motion of the seat belt and improving its protective effect on the child. Up to four second fixing points can be used to install the side wing portion using a smaller number of fixing points. Combined with the first fixing point and the third fixing point described below, this ensures the stability of the side cover installation. The seat portion corresponds to the seat surface and is used to close the side of the seat body corresponding to the seat surface. The crotch portion corresponds to the position of the child's legs when sitting, and up to four third fixing points on the crotch portion can fix the crotch portion to the seat body. Through the cooperation of the first, second, and third fixing points, a fixed connection between the side cover and the seat body can be achieved using a smaller number of fixing points. The top of the backrest portion can be fixed using the first fixing point, and the bottom of the backrest portion can be further fixed using the third fixing points on the crotch portion. The seat portion, located between the crotch portion and the backrest portion, does not require a separate fixing point and can be indirectly fixed using the fixing of the side wing portion and the crotch portion. The embodiments of this application can reduce the number of fixing points while ensuring the stability of the connection between the side cover and the seat body, simplifying the overall structure of the side cover and improving the efficiency of side cover assembly and disassembly.

[0018] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0019] Reference Figures 1 to 5 As shown, the first aspect of this application proposes a child safety seat that, while ensuring the stability of the connection between the side cover and the seat body, reduces the number of fixing points, simplifies the overall structure of the side cover, and improves the efficiency of disassembly and assembly of the side cover.

[0020] In some embodiments of this application, the child safety seat includes a seat body 100 and a side cover 200 installed on the side of the seat body 100. The seat body 100 includes an angled seat surface 110 and a backrest 120. The seat body 100 is the main structure of the child safety seat and is the position for carrying the child. The side cover 200 is an auxiliary reinforcement structure for the child safety seat, which can form a protective barrier with the side of the seat body 100 to protect the child. The seat surface 110 of the seat body 100 is the position where the child sits, and the child's buttocks and thighs will be on the seat surface 110. The backrest 120, which is angled to the seat surface 110, is used to support the child's back and waist, improving the stability of the child's seating. A headrest 300 can be provided on the backrest 120 as needed. The headrest 300 can protect the child's head. The height of the headrest 300 can be adjusted to accommodate children of different heights, making the child's seating safer and more comfortable.

[0021] It should be noted that, referring to Figure 1Specifically, the headrest 300 and the backrest 120 can be movably connected and adjustable through the adjustment component 310. The adjustment component 310 can include an adjustment element for auxiliary adjustment, which can be a lever or a paddle. When the adjustment element is moved, the headrest 300 and the backrest 120 can be in a relatively movable state, and the position of the headrest 300 can be adjusted as needed. When the adjustment element is stopped, the headrest 300 and the backrest 120 are in a relatively fixed state, and the headrest 300 can be maintained in the adjusted position.

[0022] It should be noted that, referring to Figure 1 A base 400 can be provided at the bottom of the seat body 100. The seat body 100 can be fixedly connected to the base 400, or the seat body 100 can be rotatably connected to the base 400.

[0023] It should be noted that, referring to Figure 1 The side cover 200 of this application can be provided on the left and right sides of the seat body 100. It not only serves a decorative purpose, but also strengthens the seat body 100 and improves the overall strength and impact resistance of the seat.

[0024] It should be noted that the total number of the three types of fixing positions can be seven, of which there is one first fixing position, three second fixing positions, and three third fixing positions. This arrangement can use a smaller number of fixing positions to fix the side cover 200, simplifying the overall structure of the side cover 200 and improving the efficiency of assembling and disassembling the side cover 200.

[0025] Reference Figure 2 The side cover 200 includes a backrest 210, a side wing 220, a seat 230, and a crotch 240. The backrest 210 is installed on one side of the backrest 120, and a first fixing position 211 is provided at the top of the backrest 210. The side wing 220 is curved, and its two ends are respectively connected to the top and bottom of the backrest 210. Up to four second fixing positions 221 are provided sequentially from one end of the side wing 220 to the other end. There is a gap between the side wing 220 and the backrest 210. The seat 230 is connected to the backrest 210 and installed on one side of the seat surface 110. The crotch 240 is connected to the seat 230, and up to four third fixing positions 241 are provided on the crotch 240. The side cover 200 is fixedly connected to the seat body 100 at the first fixing position 211, the second fixing position 221, and the third fixing position 241.

[0026] Based on the above embodiments of this application, the backrest 210 can close one side of the backrest 120, and the backrest 210 can be fixed to the backrest 120 by the first fixing position 211 provided at the top; the side wing 220 can form a certain protection on the side of the backrest 120, reducing the possibility of the child seat detaching from the side. After the two ends of the side wing 220 are respectively connected to the top and bottom of the backrest 210, the curved side wing 220 can form a gap between the side wing 220 and the backrest 210, so that the seat belt can pass through the gap, thereby increasing the range of motion of the seat belt and improving the protective effect of the seat belt on the child. Up to four second fixing positions 221 can be used to install the side wing 220 with a small number of fixing positions. Combined with the first fixing position 211 and the third fixing position 241 described below, this ensures the stability of the side cover 200 installation. The seat portion 230 can correspond to the seat surface 110 and is used to close the side of the seat body 100 corresponding to the seat surface 110. The hip portion 240 corresponds to the position of the child's legs when riding, and up to four third fixing positions 241 provided on the hip portion 240 can fix the hip portion 240 to the seat body 100. The cooperation of the first fixing position 211, the second fixing position 221, and the third fixing position 241 allows for a fixed connection between the side cover 200 and the seat body 100 using a smaller number of fixing positions. Specifically, the top of the backrest 210 can be fixed using the first fixing position 211, and the bottom of the backrest 210 can be further fixed using the third fixing position 241 on the crotch area 240. The seat portion 230, located between the crotch area 240 and the backrest 210, does not require a separate fixing position and can be indirectly fixed using the side wing portion 220 and the crotch area. This embodiment of the application reduces the number of fixing positions while ensuring the stability of the connection between the side cover 200 and the seat body 100, simplifying the overall structure of the side cover 200 and improving the efficiency of its assembly and disassembly.

[0027] It should be noted that, referring to Figure 3 The seat body 100 is provided with a backrest docking part 150, a side wing docking part 160, a seat docking part 170, and a crotch docking part 180. The backrest docking part 150 corresponds to the backrest part 210 on the side cover 200 and is fixedly connected by the cooperation of a first docking position 151 and a first fixing position 211. The side wing docking part 160 corresponds to the side wing part 220 on the side cover 200 and is fixedly connected by the cooperation of a second docking position 161 and a second fixing position 221. The number of second docking positions 161 and second fixing positions 221 are the same and correspond one-to-one. The seat docking part 170 corresponds to the seat part 230 on the side cover 200. The crotch docking part 180 corresponds to the crotch part on the side cover 200 and is fixedly connected by the cooperation of a third docking position 181 and a third fixing position 241. The number of third docking positions 181 and third fixing positions 241 are the same and correspond one-to-one.

[0028] Taking the first mating position 151 and the first fixing position 211 as examples, one of the first mating position 151 and the first fixing position 211 can be a through hole, and the other can be a threaded hole. In this case, the first mating position 151 and the first fixing position 211 can be connected by bolts, screws, or screws, thereby fixing the backing part 210 to the top of the backing mating part 150. The threaded hole can be set as a through hole or a blind hole. Alternatively, both the first mating position 151 and the first fixing position 211 can be set as through holes to achieve fixation by corresponding fasteners. The cooperation of the second mating position 161 and the second fixing position 221, and the cooperation of the third mating position 181 and the third fixing position 241 are similar to the above cooperation methods, and will not be described in detail here.

[0029] In some embodiments of this application, the crotch portion 240 extends upward toward the seat surface 110 and forms a half armrest, the half armrest having two spaced-apart third fixing positions 241; The crotch portion 240 extends downward toward the seat surface 110 and forms a fixing plate, on which a third fixing position 241 is provided.

[0030] Based on the embodiments described above, the aforementioned half-armrest is part of the side cover 200. After being fixed to the seat body 100, it can form a complete armrest. The armrest provides a place for children's hands to rest and grasp, improving their stability while seated. The fixing plate extending below the crotch area 240 better secures the crotch area 240 to the seat body 100, improving the connection stability of the crotch area 240. This structure eliminates the need for fixing the middle portion of the crotch area 240, reducing the number of fixing points and increasing the speed of assembling and disassembling the side cover 200.

[0031] It should be noted that, referring to Figure 1 The seat 110 of this application is provided with a flexible seat cushion 130. The flexible seat cushion 130 can extend to the side opposite to the half of the armrest, forming the other half of the armrest. This allows the part of the armrest near the inside of the seat to be soft, improving the comfort of children when placing or gripping it. The flexible seat cushion 130 can be directly fixed to the crotch area, or it can extend from the seat body 100 near the crotch area 240 to form a mounting plate. The flexible seat cushion 130 and the crotch area 240 can be fixed to the mounting plate respectively.

[0032] In some embodiments of this application, the side wing 220 has an arc-shaped structure, and the arc-shaped structure is provided with three second fixing positions 221, which are evenly arranged along the arc-shaped extension direction.

[0033] Based on the above embodiments of this application, the arc-shaped side wing portion 220 can make the structure of the side wing portion 220 smoother and more aesthetically pleasing. Three second fixing positions 221 can fix the side wing portion 220 to the side wing docking portion 160 of the seat body 100. After the three second fixing positions 221 are evenly arranged along the arc-shaped extension direction, it can ensure uniform force distribution and improve the stability of the side wing portion 220 after fixing.

[0034] It should be noted that the three second fixing positions 221 mentioned above can be evenly spaced on the side wing 220. The arc-shaped structure is not necessarily a circular arc; it can also be a parabola, an exponential line, an elliptical arc, etc. The arc-shaped structure is only a portion of the corresponding shape.

[0035] It should be noted that the second fixing position 221 of this application is not limited to three, but can also be one or two. When one is set, the second fixing position 221 can be set in the middle position of the side wing 220; when one is set, the two second fixing positions 221 can be evenly spaced along the arc structure.

[0036] In some embodiments of this application, two side covers 200 are provided, with side covers 200 respectively provided on opposite sides of the seat body 100.

[0037] Based on the above embodiments of this application, the aforementioned opposite sides can be the left and right sides of the seat body 100. That is to say, the two side covers 200 can be respectively set on the left and right sides of the seat body 100. The two side covers 200 can not only play a decorative role, but also strengthen the seat body 100, making the entire seat less prone to damage and improving the overall strength and impact resistance of the seat.

[0038] In some embodiments of this application, the first fixing position 211, the second fixing position 221 and the third fixing position 241 are fixing holes, and the side cover 200 is connected to the seat body 100 through a fastener passing through the fixing hole.

[0039] Based on the embodiments described above, the fixing holes can be through holes or threaded holes, and the threaded holes can be blind holes or through holes. Specifically, the backrest 210 can be fixedly connected by the cooperation of the first mating position 151 and the first fixing position 211; the side wing 220 can be fixedly connected by the cooperation of the second mating position 161 and the second fixing position 221, the number of the second mating positions 161 and the second fixing positions 221 are the same and correspond one-to-one; the seat mating part 170 abuts against the seat part 230; and the crotch 240 can be fixedly connected by the cooperation of the third mating position 181 and the third fixing position 241, the number of the third mating positions 181 and the third fixing positions 241 are the same and correspond one-to-one. Taking the first mating position 151 and the first fixing position 211 as examples, one of the first mating position 151 and the first fixing position 211 can be a through hole, and the other can be a threaded hole. In this case, the first mating position 151 and the first fixing position 211 can be connected by bolts, screws, or screws, thereby fixing the backing part 210 to the top of the backing mating part 150. The cooperation of the second mating position 161 and the second fixing position 221, and the cooperation of the third mating position 181 and the third fixing position 241 are similar to the above cooperation methods, and will not be described in detail here.

[0040] Reference Figure 4 and Figure 5 In some embodiments of this application, a first reinforcing structure 250 is provided on the side of the side cover 200 near the seat body 100.

[0041] Based on the above embodiments of this application, the first reinforcing structure 250 can strengthen the fixing hole, reduce or even avoid stress concentration and damage to the side cover 200 at the fixing hole location, and can thicken the fixing hole location as needed to further improve the strength of the fixing hole location and increase the service life of the side cover 200.

[0042] In some embodiments of this application, the backrest portion 210 in the side cover 200 abuts against the seat body 100, and a second reinforcing structure 260 is provided on the side of the side cover 200 near the seat body 100.

[0043] Based on the above embodiments of this application, the second reinforcing structure 260 is used to strengthen the overall structure of the side cover 200, avoid bending deformation of the side cover 200, and better maintain the shape of the side cover 200.

[0044] In some embodiments of this application, the backrest portion 210 extends toward the backrest 120, and a third reinforcing structure 270 is provided on the extended portion. The third reinforcing structure 270 is provided with a clearance structure near the backrest 120, and the shape of the clearance structure is adapted to the shape of the abutment position of the backrest 120.

[0045] Based on the above embodiments of this application, the third reinforcing structure 270 can strengthen the backrest 210, and the side cover 200 and seat body 100 can be more tightly integrated through the setting of the avoidance structure, so as to better integrate them into one body and greatly improve the overall strength and impact resistance of the seat.

[0046] Reference Figure 5 In some embodiments of this application, the avoidance structure is an avoidance notch 271 on the third reinforcing structure 270, and the avoidance notch 271 is adapted to the corresponding part of the backrest 120.

[0047] Based on the above embodiments of this application, the shape of the clearance notch 271 can be set as needed, specifically referring to the corresponding part of the backrest 120. For example, if the part of the backrest 120 corresponding to the clearance notch 271 is L-shaped, the clearance notch 271 can be set to an L-shape of the corresponding size to avoid the corresponding position of the seat body 100, thereby facilitating the installation of the side cover 200. This setting can make the side cover 200 and the seat body 100 fit more tightly and better integrate them into one unit, greatly improving the overall strength and impact resistance of the seat.

[0048] The child safety seat described in this application can be used in conjunction with a vehicle.
