Description

Technical Field

[0001] This utility model relates to the field of child seat technology, and in particular to a child safety seat and a child safety seat system. Background Technology

[0002] To meet the childcare needs of families with children, various child seats specifically designed for children have appeared on the market. These include high chairs for easy feeding or dining, and car seats installed in car seats to ensure the safety of children while traveling. These child seats utilize their structural features to achieve specific functional effects, providing convenience for parents while ensuring the comfort and safety of children.

[0003] To ensure that child seats can adapt to various usage scenarios, the seat body is generally designed to rotate, allowing the child to change their orientation within the seat. Typically, a rotating handle is used to adjust the rotation angle; however, currently, the rotating handle may interfere with other components of the seat, affecting the smoothness of rotation. Utility Model Content

[0004] The main purpose of this utility model is to propose a child safety seat and a child safety seat system, which aims to solve the technical problem that when operating the rotating handle, the rotating handle may interfere with other structures of the child seat, thus affecting the smoothness of the child seat body during rotation.

[0005] To achieve the above objectives, this utility model proposes a child safety seat, comprising:

[0006] The seat body has a rotating disk at its bottom, and a guide plate extends outward from the side of the rotating disk away from the seat body.

[0007] The base is disposed below the seat body and the base and the seat body are connected by a rotating shaft. The base is provided with a guide groove along the circumferential direction. The guide plate is configured to be connected to the guide groove and can rotate within the guide groove. The base includes a first snap-fit ​​part and a second snap-fit ​​part disposed opposite to each other at the guide groove. The outer walls of the first snap-fit ​​part and the second snap-fit ​​part are both provided with a first guide rib protruding from them.

[0008] A rotating handle is disposed on the seat body, the rotating handle is provided with a third locking portion, the rotating handle is configured to move toward the base to lock the rotating handle, and the rotating handle is configured to move away from the base to unlock the rotating handle.

[0009] When the rotating handle is in the locked state, the third locking part can be locked to the first locking part or the second locking part, and the rotating handle is in contact with the first guide rib; when the rotating handle is in the unlocked state, the third locking part can disengage from the first locking part or the second locking part.

[0010] Specifically, in this embodiment, since the first guide rib elevates the rotating handle, it will not interfere with other structures of the base during the movement of the rotating handle (for example, the rotating handle will not interfere with the locking iron plate of the base), thereby ensuring the sensitivity when adjusting the rotating handle and improving the smoothness of the seat body when rotating.

[0011] In some embodiments, the first locking portion includes a first locking groove, the second locking portion includes a second locking groove, and the third locking portion includes a locking block. The locking block can be engaged in the first locking groove or the second locking groove to put the rotating handle in the locked state, and the locking block can disengage from the first locking groove or the second locking groove to put the rotating handle in the unlocked state.

[0012] Specifically, in this embodiment, the rotating handle and the first and second locking parts are coupled in the manner described above. This method is simple in structure and easy to operate, ensuring the stable positioning of the seat body at the first and second rotation angles, while also allowing the seat body to switch flexibly between the first and second rotation angles.

[0013] In some embodiments, the rotating disk is provided with a limiting post, and the rotating handle is provided with a limiting hole. The limiting hole and the limiting post cooperate to connect the rotating handle and the rotating disk. An elastic element is wound around the outer wall of the limiting post. One end of the elastic element is limited to the limiting post by a screw, and the other end of the elastic element abuts against the inner bottom of the rotating handle.

[0014] Specifically, in this embodiment, the elastic element simplifies the operation of the rotating handle and improves the adjustment accuracy of the rotating handle.

[0015] In some embodiments, a second guide rib is provided protruding on the side of the rotating disk near the seat body, and the bottom of the seat body contacts the second guide rib.

[0016] Specifically, in this embodiment, the second guide rib can elevate the seat body, making the seat body and the rotating disk suspended. By adopting the above structure, the surface contact between the seat body and the rotating disk can be transformed into the line contact between the seat body and the second guide rib, thereby effectively reducing the friction force on the seat body when sliding, improving the smoothness of the seat body when sliding, and ensuring that the seat body saves time and effort when adjusting the pitch angle.

[0017] In some embodiments, the child safety seat includes a headrest assembly slidably connected to the seat body, and a third guide rib protruding from the side of the seat body near the headrest assembly, with the headrest assembly in contact with the third guide rib.

[0018] Specifically, in this embodiment, the third guide rib can elevate the headrest assembly, making the headrest assembly and the seat body suspended. By adopting the above structure, the surface contact between the headrest assembly and the seat body can be transformed into a line contact between the headrest assembly and the third guide rib, thereby effectively reducing the friction force on the headrest assembly when sliding, improving the smoothness of the headrest assembly when sliding, and ensuring that the headrest assembly is time-saving and labor-saving when sliding.

[0019] In some embodiments, the third guide rib extends in a direction parallel to the sliding direction of the headrest assembly.

[0020] Specifically, in this embodiment, by adopting the above structure, the third guide rib can provide guidance for the headrest assembly during the sliding process, preventing the headrest assembly from deviating during sliding. Moreover, by adopting the above-mentioned arrangement, the smoothness of the headrest assembly during sliding can be further improved.

[0021] In some embodiments, the seat body is provided with a seat belt, and the headrest assembly is provided with a fixing cover on the side near the seat body. The fixing cover is connected to the headrest assembly by a locking pin, the end of the locking pin protruding from the fixing cover, and the seat belt and the protruding end of the locking pin are in contact.

[0022] Specifically, in this embodiment, since the protruding ends of the seat belt and the locking pin are in contact, there is a small contact area between the seat belt and the locking pin, that is, there is a small friction between the seat belt and the locking pin. This can improve the smoothness of the seat belt when stretching, prevent the seat belt from getting stuck, and reduce the difficulty of operating the seat belt.

[0023] In some embodiments, buffer members are provided on both sides of the seat body, the buffer members are provided with clearance holes, and the side walls of the seat body are provided with connecting holes. Connecting members are sequentially inserted into the clearance holes and the connecting holes, and the connecting members are used to connect the buffer members to the side walls of the seat body.

[0024] Specifically, in this embodiment, the buffer provides cushioning protection to ensure the safety of the seat body during use. By providing clearance holes on the buffer, the connection difficulty between the buffer and the side walls of the seat body can be reduced, the connection strength between the buffer and the side walls of the seat body can be improved, and the connection can be ensured that the connecting parts will not damage the buffer, thus maintaining the structural integrity of the buffer.

[0025] In some embodiments, the two side walls of the seat body are provided with a plurality of first ventilation holes, and the buffer is provided with a plurality of second ventilation holes, the plurality of second ventilation holes and the plurality of first ventilation holes being respectively arranged opposite to each other.

[0026] Specifically, in this embodiment, by providing a first vent hole on the side wall of the seat body and a second vent hole on the buffer, and by having the second vent hole and the first vent hole overlap, the air circulation speed between the seat body and the external environment can be increased, thereby improving the breathability of the seat body and enhancing its comfort.

[0027] Correspondingly, this utility model also proposes a child safety seat system, including:

[0028] The child safety seat described in any of the above embodiments;

[0029] The child safety seat is configured to be attached to the base to secure it in place.

[0030] Specifically, in this embodiment, by applying the above-mentioned child safety seat, it is easier to adjust the rotation angle of the child safety seat, improve the smoothness of the child safety seat during adjustment, and make the child safety seat adjustment time-saving and labor-saving.

[0069] To meet the childcare needs of families with children, various child seats specifically designed for children have appeared on the market. These include high chairs for easy feeding or dining, and car seats installed in car seats to ensure the safety of children while traveling. These child seats utilize their structural features to achieve specific functional effects, providing convenience for parents while ensuring the comfort and safety of children.

[0070] To ensure that child seats can adapt to various usage scenarios, the seat body is generally designed to rotate, allowing the child to change their orientation within the seat. Typically, a rotating handle is used to adjust the rotation angle; however, currently, the rotating handle may interfere with other components of the seat, affecting the smoothness of rotation.

[0071] Based on this, in order to solve the technical problem that the rotating handle 400 may interfere with other structures of the child seat when operating it, thus affecting the smoothness of the child seat body 100 during rotation, refer to Figures 1 to 12This utility model provides a child safety seat, which includes a seat body 100, a base 300, and a rotating handle 400. A rotating disk 200 is provided at the bottom of the seat body 100, and guide plates 210 extend outward from the side of the rotating disk 200 away from the seat body 100. For example, the guide plates 210 can be arranged in a circle around the circumference of the rotating disk 200, or there can be multiple guide plates 210, which can be spaced apart around the circumference of the rotating disk 200. A base 300 is disposed below the seat body 100, and the base 300 and the seat body 100 are connected by a rotating shaft. The base 300 has a guide groove 310 arranged circumferentially. A guide plate 210 is configured to connect to and rotate within the guide groove 310. The base 300 includes a first engaging portion 320 and a second engaging portion 330 disposed opposite each other at the guide groove 310. A first guide rib 340 protrudes from the outer walls of both the first engaging portion 320 and the second engaging portion 330. A rotating handle 400 is disposed on the seat body 100 and has a third engaging portion 410. The rotating handle 400 is configured to move towards the base 300 to lock, and to move away from the base 300 to unlock. When the rotating handle 400 is in the locked state, the third locking part 410 can be locked to the first locking part 320 or the second locking part 330, and the rotating handle 400 and the first guide rib 340 are in contact; when the rotating handle 400 is in the unlocked state, the third locking part 410 can be disengaged from the first locking part 320 or the second locking part 330.

[0072] Specifically, in this embodiment, it is assumed that when the third latching part 410 is latched into the first latching part 320, the seat body 100 has a first rotation angle relative to the base 300, and when the third latching part 410 is latched into the second latching part 330, the seat body 100 has a second rotation angle relative to the base 300. When the rotating handle 400 is operated to adjust the seat body 100 to rotate from the first rotation angle to the second rotation angle, an external force is first applied to the rotating handle 400, causing the rotating handle 400 to move away from the base 300. At this time, the third locking part 410 gradually disengages from the first locking part 320. When the rotating handle 400 is in the unlocked state, the third locking part 410 completely disengages from the first locking part 320, and the rotating handle 400 no longer positions and constrains the seat body 100. After being subjected to force, the seat body 100 can rotate from the first rotation angle to the second rotation angle (for example, the angle α that the seat body 100 can rotate can satisfy: 0°≤α≤360°). When the seat body 100 rotates to the second rotation angle, a counterforce is first applied to the rotating handle 400, causing it to move closer to the base 300. At this time, the third engaging portion 410 gradually engages with the second engaging portion 330. When the rotating handle 400 is locked, the third engaging portion 410 is fully engaged with the second engaging portion 330, ensuring a stable connection between the seat body 100 and the base 300. This positions the seat body 100 at the second rotation angle, allowing for adjustment of the seat body 100's rotation angle and enabling the child safety seat to adapt to different usage situations. It should be noted that the steps for operating the rotating handle 400 to adjust the seat body 100 from the second rotation angle to the first rotation angle are similar to the above process and will not be repeated here.

[0073] Because the first guide rib 340 elevates the rotating handle 400, it will not interfere with other structures of the base 300 during the movement of the rotating handle 400 (for example, the rotating handle 400 will not interfere with the locking iron plate of the base 300), thereby ensuring the sensitivity when adjusting the rotating handle 400 and improving the smoothness of the seat body 100 when rotating.

[0074] In some embodiments, refer to Figures 2-1 to 4The present invention provides a specific structural form for the third locking part 410 and the first locking part 320 and the second locking part 330 to achieve locking. For example, the first locking part 320 includes a first locking groove 321, the second locking part 330 includes a second locking groove 331, and the third locking part 410 includes a locking block 411. The locking block 411 can be locked in the first locking groove 321 or the second locking groove 331 to lock the rotating handle 400, and the locking block 411 can be disengaged from the first locking groove 321 or the second locking groove 331 to release the rotating handle 400.

[0075] Specifically, in this embodiment, by engaging the locking block 411 within the first locking groove 321, the rotating handle 400 and the first locking portion 320 are locked, ensuring that the seat body 100 can be positioned at the first rotation angle. By removing the locking block 411 from the first locking groove 321, the rotating handle 400 and the first locking portion 320 are unlocked, ensuring that the seat body 100 can rotate freely and achieve angle switching of the seat body 100. Similarly, by engaging the locking block 411 within the second locking groove 331, the rotating handle 400 and the second locking portion 330 are locked, ensuring that the seat body 100 can be positioned at the second rotation angle. By removing the locking block 411 from the second locking groove 331, the rotating handle 400 and the second locking portion 330 are unlocked, ensuring that the seat body 100 can rotate freely and achieve angle switching of the seat body 100. The above-mentioned cooperation method has a simple structure and is easy to operate. It can ensure the stable positioning of the seat body 100 at the first rotation angle and the second rotation angle, and at the same time, it can ensure the flexible switching of the seat body 100 between the first rotation angle and the second rotation angle.

[0076] In some embodiments, refer to Figures 2-1 to 2-3 ,as well as Figure 10 The rotating disk 200 is provided with a limiting post 412, and the rotating handle 400 is provided with a limiting hole. The limiting hole and the limiting post 412 cooperate to connect the rotating handle 400 and the rotating disk 200. The limiting post 412 is used to limit and guide the rotating handle 400 when it moves up and down. An elastic element 500 (for example, the elastic element 500 can be a spring) is wrapped around the outer wall of the limiting post 412. One end of the elastic element 500 is limited to the limiting post 412 by a screw 800, and the other end of the elastic element 500 abuts against the inner bottom of the rotating handle 400. In actual assembly, the rotating handle 400 is first sleeved on the limiting post 412, then the elastic element 500 is sleeved on the limiting post 412, and finally the screw 800 is connected to the limiting post 412. The screw 800 limits the elastic element 500.

[0077] Specifically, in this embodiment, when the locking block 411 disengages from the first locking groove 321 or the second locking groove 331, the rotating handle 400 moves upward along the limiting post 412. At this time, the elastic element 500 is compressed. Through the resistance of the elastic element 500, the operator can intuitively feel whether the rotating handle 400 has moved into place (for example, as the resistance felt by the operator increases, the rotating handle 400 gradually moves into place), preventing the operator from doing unnecessary work. After the seat body 100 has rotated into place, the external force applied to the rotating handle 400 is removed. At this time, the elastic element 500 has a tendency to recover its elastic deformation. Under the elastic action of the elastic element 500, the rotating handle 400 moves downward along the limiting post 412, thereby realizing that the locking block 411 automatically engages in the first locking groove 321 or the second locking groove 331. The elastic element 500 simplifies the operation process of the rotating handle 400 and improves the adjustment accuracy of the rotating handle 400.

[0078] In some embodiments, refer to Figure 7 and Figure 9 To improve the comfort of child safety seats, the tilt angle of the seat body 100 can typically be adjusted, allowing the seat body 100 to slide relative to the rotating disc 200. To facilitate this sliding, a second guide rib 220 protrudes from the side of the rotating disc 200 near the seat body 100, and the bottom of the seat body 100 contacts the second guide rib 220. For example, the second guide rib 220 may have a tapered structure from one end near the rotating disc 200 to the end away from the rotating disc 200.

[0079] Specifically, in this embodiment, the second guide rib 220 can elevate the seat body 100, making the seat body 100 and the rotating disk 200 suspended. By adopting the above structure, the surface contact between the seat body 100 and the rotating disk 200 can be transformed into a line contact between the seat body 100 and the second guide rib 220, thereby effectively reducing the friction force on the seat body 100 when sliding, improving the smoothness of the seat body 100 when sliding, and ensuring that the seat body 100 saves time and effort when adjusting the pitch angle.

[0080] In some embodiments, the space between the second guide rib 220 and the rotating disk 200 can be an injection-molded structure.

[0081] In some embodiments, refer to Figure 1 , Figure 5 and Figure 7The child safety seat includes a headrest assembly 600, which is slidably connected to a seat body 100. A third guide rib 110 protrudes from the side of the seat body 100 near the headrest assembly 600, and the headrest assembly 600 and the third guide rib 110 are in contact. Preferably, the third guide rib 110 extends in a direction parallel to the sliding direction of the headrest assembly 600. For example, if the headrest assembly 600 slides vertically relative to the seat body 100, then the third guide rib 110 is vertically positioned. The third guide rib 110 may have a tapered structure from one end near the seat body 100 to the end away from the seat body 100, and the end face of the third guide rib 110 near the headrest assembly 600 may be an arc-shaped end face. The third guide rib 110 and the seat body 100 may be an injection-molded structure.

[0082] Specifically, in this embodiment, the third guide rib 110 can elevate the headrest assembly 600, making the headrest assembly 600 and the seat body 100 suspended. By adopting the above structure, the surface contact between the headrest assembly 600 and the seat body 100 can be transformed into a line contact between the headrest assembly 600 and the third guide rib 110, thereby effectively reducing the friction force on the headrest assembly 600 when sliding, improving the smoothness of the headrest assembly 600 when sliding, and ensuring that the headrest assembly 600 is time-saving and labor-saving when sliding.

[0083] In some embodiments, refer to Figure 2-1 , Figure 5 and Figure 6 The seat body 100 is equipped with a seat belt, and the headrest assembly 600 is provided with a fixing cover 610 on the side near the seat body 100. The fixing cover 610 is connected to the headrest assembly 600 through a locking pin 620. The end of the locking pin 620 protrudes from the fixing cover 610, and the seat belt contacts the protruding end of the locking pin 620.

[0084] Specifically, in this embodiment, when a child sits on the seat body 100 and needs to fasten the seat belt, the seat belt and the locking pin 620 have a small contact area due to the contact between their protruding ends. This means there is less friction between the seat belt and the locking pin 620, which improves the smoothness of the seat belt when it is stretched, preventing jamming and reducing the difficulty of operating it. Furthermore, a rotating shaft is provided on the side of the headrest assembly 600 near the seat body 100, around which the seat belt can be wound. When the seat belt is stretched, the rotating shaft provides a sliding force, further improving the smoothness of the seat belt during sliding and making it easier and less time-consuming to operate.

[0085] In some embodiments, refer to Figure 7 and Figure 8Both sides of the seat body 100 are provided with cushioning elements 700. The cushioning elements 700 have a loose and porous structure, which can play a good role in cushioning protection when subjected to external impact. For example, the cushioning elements 700 can be foam or sponge. The cushioning elements 700 are provided with clearance holes 710, and the two side walls 120 of the seat body 100 are provided with connecting holes 121. Connectors are sequentially inserted into the clearance holes 710 and the connecting holes 121. The connectors are used to connect the cushioning elements 700 to the two side walls 120 of the seat body 100. For example, the connecting hole 121 can be a fixing pin hole, and the connector can be a fixing pin. Alternatively, the connecting hole 121 can be a threaded hole, and the connector can be a bolt or screw.

[0086] Specifically, in this embodiment, when assembling the buffer 700 to the two side walls 120 of the seat body 100, the buffer 700 can first be glued to the two side walls 120 of the seat body 100 using adhesives such as glue or tape, to achieve initial positioning of the buffer 700 on the two side walls 120 of the seat body 100. This also facilitates multiple adjustments to the positioning position of the buffer 700 on the two side walls 120 of the seat body 100, ensuring the positioning accuracy of the buffer 700 on the two side walls 120 of the seat body 100. After the buffer 700 is positioned, it can be fixedly connected to the two side walls 120 of the seat body 100 by connecting members that are sequentially inserted into the clearance hole 710 and the connection hole 121, achieving final positioning of the buffer 700 on the two side walls 120 of the seat body 100, and improving the connection strength and stability between the buffer 700 and the two side walls 120 of the seat body 100. Meanwhile, by providing clearance holes 710 on the buffer 700, the connection difficulty of the buffer 700 to the two side walls 120 of the seat body 100 can be reduced, and the connection can be guaranteed not to damage the buffer 700, so as to maintain the structural integrity of the buffer 700.

[0087] In some embodiments, refer to Figure 7 and Figure 8The seat body 100 has multiple first ventilation holes 122 on both side walls 120, and the cushioning member 700 has multiple second ventilation holes 720. The multiple second ventilation holes 720 and the multiple first ventilation holes 122 are respectively arranged opposite to each other. In other words, the multiple second ventilation holes 720 and the multiple first ventilation holes 122 are respectively overlapped. For example, the multiple first ventilation holes 122 and the multiple second ventilation holes 720 can be elongated oval holes that are parallel to each other and inclined. Alternatively, the multiple first ventilation holes 122 and the multiple second ventilation holes 720 can be radially expanded circular holes, that is, from one end of the side wall 120 of the seat body 100 to the opposite end of the side wall 120 of the seat body 100, the density and pore size of the multiple first ventilation holes 122 gradually increase simultaneously. Similarly, from one end of the cushioning member 700 to the opposite end of the cushioning member 700, the density and pore size of the multiple second ventilation holes 720 gradually increase simultaneously. It is understandable that the first vent 122 and the second vent 720 are not limited to adopting the above-mentioned structure and arrangement. As long as the first vent 122 and the second vent 720 can increase the ventilation area and improve the overall appearance of the child safety seat, it is acceptable.

[0088] Specifically, in this embodiment, by providing a first vent 122 on the side wall 120 of the seat body 100 and a second vent 720 on the buffer 700, and by having the second vent 720 and the first vent 122 overlap, the air circulation speed between the seat body 100 and the external environment can be increased, thereby improving the breathability of the seat body 100 and enhancing the comfort of the seat body 100.

[0089] Correspondingly, another embodiment of this utility model also provides a child safety seat system, which includes the child safety seat in any of the above embodiments. The child safety seat system also includes a base, to which the child safety seat is configured to be connected for securing the child safety seat. For example, the child safety seat system may include a car component, meaning the child safety seat can be installed on a car seat to facilitate travel with a child in the car.

[0090] Specifically, in this embodiment, by applying the above-mentioned child safety seat, it is easier to adjust the rotation angle of the child safety seat, improve the smoothness of the child safety seat during adjustment, and make the child safety seat adjustment time-saving and labor-saving.

[0091] Thanks to the improvements to the child safety seats described above, the child safety seat system in this embodiment has the same technical effects as the aforementioned child safety seats, which will not be repeated here.

[0092] It should be noted that other aspects of the child safety seat and child safety seat system disclosed in this utility model can be found in the prior art, and will not be repeated here.

[0093] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
