[0064] Example 1

[0065] like Figures 1-6 As shown, the child safety seat of this utility model includes a seat body and a side protection mechanism.

[0066] The seat body comprises a base 11 and a seat shell arranged on the base 11. The seat shell comprises a seat 12 for supporting the buttocks of a child and a backrest 13 for supporting the back of the child, the backrest 13 being arranged at the rear of the seat 12. The seat body further comprises a headrest 14 for supporting the head of the child, the headrest 14 being preferably arranged on the backrest 13 in a slidable manner so as to be adjustable in height on the backrest 13, so that the child safety seat can be adapted for use by children of different ages.

[0067] The side protection mechanism is arranged at the side of the headrest 14. In this embodiment, the side protection mechanism has a folded state and an unfolded state. When the side protection mechanism is not used, the side protection mechanism is in the folded state, in which the side protection mechanism is close to the side of the headrest 14, so as to avoid the side protection mechanism from forming an obstacle in the car and to avoid the side protection mechanism from being touched by a passenger sitting beside the child safety seat, and to facilitate storage. Moreover, the headrest 14 can be adjusted in position by sliding up and down relative to the backrest 13, as shown in Figures 1-3 When the side protection mechanism is used, the headrest 14 is extended upward above the backrest 13, and the side protection mechanism is in the unfolded state, in which the side protection mechanism extends outward from the side of the headrest 14 and stands on the outside of the headrest 14 and at the same time is located outside the side of the backrest 13, as shown in Figures 4-6 Thus, when the car is subjected to a side impact, the impact energy generated by the side impact can be buffered by the side protection mechanism, so as to achieve the purpose of protecting the child from the side. The child safety seat has a central plane extending in the front-rear direction, the inside here refers to the side facing the central plane, and the outside is opposite to the inside, referring to the side facing away from the central plane.

[0068] The side protection mechanism comprises a support member 2 and a bearing portion 8.

[0069] In this embodiment, one end of the support member 2 is rotationally connected to the side of the headrest 14, and the bearing portion 8 is arranged at the other end of the support member 2. Preferably, the bearing portion 8 is arranged integrally with the support member 2, and the cross-sectional areas of the support member 2 and the bearing portion 8 are the same or have a small difference, i.e. the support member 2 and the bearing portion 8 are a whole structure.

[0070] When the side protection mechanism is in the folded state, the support member 2 and the bearing portion 8 are mostly accommodated in the side of the headrest 14, as shown in Figures 1-3 When the side protection mechanism is in the unfolded state, the headrest 14 is extended upward above the backrest 13, the support member 2 is rotated to the outside of the side of the headrest 14 and stands on the outside of the side of the headrest 14, and at least the bearing portion 8 is located outside the side of the backrest 13, as shown in Figures 4-6

[0071] ​The side protection mechanism may also include a base 3, which is embedded in the side of the headrest 14, and the support member 2 is rotatably connected to the base 3. In this way, the side protection mechanism can be installed as a whole on the side of the headrest 14, making the installation of the side protection mechanism convenient. Moreover, if the side protection mechanism is damaged, it can be replaced as a whole.

[0072] The base 3 is provided with a receiving groove 33. When the side protection mechanism is in the folded state, the support member 2 and the bearing part 8 are all or most of the same and are received in the receiving groove 33, such as... Figures 7-9 As shown. When the side protection mechanism is in the deployed state, the support member 2 and the bearing part 8 mostly extend from the receiving groove 33, as... Figures 10-12 As shown.

[0073] The side protection mechanism also includes a first locking mechanism, which is disposed between the base 3 and the support member 2. When the side protection mechanism is in the unfolded state, the first locking mechanism is in the locked state, thereby locking the relative position of the support member 2 and the base 3. When the first locking mechanism is unlocked, the support member 2 can rotate relative to the base 3, thereby converting the side protection mechanism into a folded state. Of course, when the side protection mechanism does not include the base 3, the first locking mechanism can be disposed between the side of the headrest 14 and the support member 2.

[0074] In this embodiment, the first locking mechanism includes a protrusion 31 disposed on one of the base 3 and the support 2, and a recess 21 disposed on the other. When the first locking mechanism is in the locked state, the protrusion 31 is inserted into the recess 21, as shown in the example. Figure 12 As shown. When the first locking mechanism is in the unlocked state, the protrusion 31 disengages from the recess 21, as... Figure 9 As shown.

[0075] In this embodiment, the support member 2 can also be slidably disposed relative to the base 3, so that the protrusion 31 can disengage from or enter the recess 21. That is, the first locking mechanism can be unlocked or locked by sliding the support member 2 relative to the base 3, which simplifies the structure of the child safety seat.

[0076] A guide structure is also provided between the support member 2 and the base 3 to guide and limit the sliding of the support member 2 when it slides relative to the base 3 to lock or unlock the first locking mechanism. The guide structure includes a guide post 32 on one of the support member 2 and the base 3, and a guide groove 22 on the other. The guide post 32 is located in the guide groove 22 and can slide along it. When the first locking mechanism is in the locked state, the guide post 32 is located at one end of the guide groove 22, such as... Figure 12 As shown. When the first locking mechanism is in the unlocked state, the guide post 32 is located at the other end of the guide groove 22, as... Figure 9 As shown.

[0077] The side protection mechanism can further comprise a second locking mechanism arranged between the support 2 and the base 3. When the side protection mechanism is in the folded state, the second locking mechanism is in the locked state, thereby locking the relative position of the support 2 and the base 3. When the second locking mechanism is unlocked, the support 2 can rotate relative to the support base 3, thereby converting the side protection mechanism to the unfolded state. As the first locking mechanism, when the side protection mechanism does not comprise the base 3, the second locking mechanism can be arranged between the side of the headrest 14 and the support 2.

[0078] In this embodiment, the second locking mechanism adopts a press-type elastic self-locking mechanism, which is simple in structure and convenient to lock and unlock. Specifically, it comprises a first locking pin 41 and a matching part 42 which can be disengaged from the first locking pin 41. When the second locking mechanism is in the locked state, the first locking pin 41 cooperates with the matching part 42, as shown in Figure 9 . When the second locking mechanism is in the unlocked state, the first locking pin 41 is disengaged from the matching part 42, as shown in Figure 12 .

[0079] Of course, the second locking mechanism can also not be arranged, and when the side protection mechanism is in the folded state, the support 2 can be accommodated in the accommodating groove 33 of the base 3. At this time, the headrest can also be slid downward, and the side protection mechanism can be kept in the folded state by the blocking of the backrest 13.

[0080] In the case where the second locking mechanism is arranged, the side protection mechanism can further comprise an elastic member 5 arranged between the support 2 and the base 3. When the second locking mechanism is unlocked, the support 2 can automatically rotate in the direction of disengaging from the accommodating groove 33 of the base 3 under the elastic force of the elastic member 5. That is, when the side protection mechanism is unlocked by pressing the first locking pin 41, the side protection mechanism can automatically convert to the unfolded state by the elastic force of the elastic member 5, which makes it convenient to convert the side protection mechanism between the folded state and the unfolded state.

[0081] In this embodiment, when the side protection mechanism converts from the folded state to the unfolded state, the support 2 automatically rotates in the direction away from the base 3 under the elastic force of the elastic member 5 after the second locking mechanism is unlocked by pressing the first locking pin 41, until the support 2 moves to the position where the side protection mechanism is in the unfolded state; the support 2 is slid relative to the base 3, so that the convex part 31 is inserted in the concave part 21, that is, the first locking mechanism is locked, as shown in Figure 12 . At this time, the side protection mechanism is in the unfolded state.

[0082] When the side protection mechanism is converted from the unfolded state to the folded state, the support 2 is slid relative to the base 3, so that the convex portion 31 is disengaged from the concave portion 21, and the first locking mechanism is unlocked; the support 2 is rotated towards the base 3 until the side protection mechanism is in the folded state, and the second locking mechanism is locked.

[0083] Embodiment 2

[0084] In this embodiment, one end of the support 2 is slidably arranged at the side of the headrest 14, and the bearing portion 8 is arranged at the other end of the support 2. When the side protection mechanism is in the folded state, the support 2 is mostly accommodated in the side of the headrest 14. When the side protection mechanism is in the unfolded state, the support 2 is slid relative to the side of the headrest 14, and mostly extends from the side of the headrest 14 to the outside of the side of the headrest 14, and at least the bearing portion 8 is located outside the side of the backrest 13.

[0085] In this embodiment, the bearing portion 8 is an end cap fixedly arranged at the other end of the support 2, and the area of the outer side surface of the end cap is not less than the cross-sectional area of the support 2 in the lateral direction. In this way, when a side impact occurs, the impact load is first applied to the outer side surface of the end cap, and since the area of the outer side surface of the end cap is relatively large, the contact area between the end cap and the door of the vehicle can be increased, so that the impact energy generated by the side impact can be effectively absorbed, and the impact force can be greatly reduced, so that the child can be better protected.

[0086] In this embodiment, like in Embodiment 1, the bearing portion 8 can also be integrally arranged with the support 2, and the cross-sectional areas of the two are the same or have a small difference, i.e., the support 2 and the bearing portion 8 are a whole structure.

[0087] In this embodiment, the first locking mechanism includes a second locking pin 6 movably arranged on one of the base 3 and the support 2, and a second locking groove 34 arranged on the other. When the first locking mechanism is in the locked state, the second locking pin 6 is inserted in the second locking groove 34, as shown in Figure 20 When the first locking mechanism is in the unlocked state, the second locking pin 6 is disengaged from the second locking groove 34, as shown in Figure 16

[0088] The second locking groove 34 can be spaced apart from each other in the sliding direction of the support 2 relative to the base 3, so that the support 2 can extend to different positions of the side of the headrest 14, so that the side protection mechanism can be adjusted in multiple gears, so that the side protection mechanism can be selected to be in a suitable gear position according to the distance between the child safety seat and the door of the vehicle, so as to ensure installation and achieve a better side protection effect.

[0089] ​The side protection mechanism further comprises an unlocking mechanism, which can unlock the first locking mechanism when the first locking mechanism operates the unlocking mechanism in the locked state. The unlocking mechanism comprises an unlocking member 7 rotatably arranged on the base 3 or the support 2, and the second locking pin 6 is arranged at one end of the unlocking member 7, and the other end of the unlocking member 7 is provided with a pressing portion 71 for pressing by a hand when unlocking. When the first locking mechanism presses the pressing portion 71 in the locked state, the unlocking member 7 rotates relative to the base 3 or the support 2, so that the second locking pin 6 can be pulled out of the second locking groove 34, and the first locking mechanism is unlocked.

[0090] In this embodiment, a second locking mechanism can be provided to lock the position of the support 2 when the side protection mechanism is in the folded state. Of course, the second locking mechanism can also not be provided, and when the side protection mechanism is in the folded state, the support 2 can be retracted into the accommodating groove 33 of the base 3.

[0091] In the case where the second locking mechanism is provided, the elastic member 5 can be provided, so that after the side protection mechanism is unlocked by the second locking mechanism in the folded state, the side protection mechanism can be automatically converted to the unfolded state by the elastic force of the elastic member 5.

[0092] Embodiment 3

[0093] In this embodiment, one end of the bearing portion 8 is rotatably connected to the other end of the support 2.

[0094] When the side protection mechanism is in the folded state, the support 2 and the bearing portion 8 are mostly accommodated in the accommodating groove 33, and are both close to the side of the headrest 14, and a first included angle is formed between the support 2 and the bearing portion 8, as shown in Figures 21-23 and Figure 25 Preferably, the support 2 and the bearing portion 8 extend in the same direction, and the outer side of the support 2 and the outer side of the bearing portion 8 are both located inside the outer side of the side of the headrest 14; or the outer side of the support 2, the outer side of the bearing portion 8, and the outer side of the side of the headrest 14 are located in the same plane, so that the appearance of the child safety seat is beautiful, and the arrangement of the side protection mechanism does not affect the passenger located beside the child safety seat when riding.

[0095] When the side protection mechanism is in the unfolded state, the support 2 and the bearing portion 8 are both pulled out of the accommodating groove 33 and extend to the outside of the side of the headrest 14, and at least the bearing portion 8 is located outside the outer side of the backrest 13, the support 2 and the bearing portion 8 extend in different directions, and a second included angle is formed between the support 2 and the bearing portion 8, and the first included angle and the second included angle are different, as shown in Figures 26-28 and Figure 30

[0096] ​When the side protection mechanism is in the unfolded state, the extension direction of the bearing part 8 is parallel to the central plane of the child safety seat, or is arranged obliquely relative to the central plane, preferably with an oblique angle of not more than 20°. The outer side of the bearing part 8 is located outside the outer side of the support 2, or the outer side of the bearing part 8 is in the same plane as the outer side of the support 2. The area of the outer side of the bearing part 8 is not less than the cross-sectional area of the support 2 in the lateral direction. In this way, when a side impact occurs, the impact load first acts on the outer side of the bearing part 8, and since the area of the outer side of the bearing part 8 is relatively large, the contact area between the bearing part 8 and the car door can be increased, thereby effectively absorbing the impact energy generated by the side impact, greatly reducing the impact force, and thus better protecting the child.

[0097] The side protection mechanism can be switched between the folded state and the unfolded state by rotating the support 2 relative to the side of the headrest 14 and rotating the bearing part 8 relative to the support 2.

[0098] The bearing part 8 can also be slidingly rotatably connected with the support 2. Alternatively, the bearing part 8 is detachably connected with the support 2.

[0099] The side protection mechanism further comprises a limiting structure arranged between the support 2 and the bearing part 8. Due to the arrangement of the limiting structure, when the side protection mechanism is switched from the folded state to the unfolded state, after the support 2 rotates the bearing part 8 as a whole to a set position, the bearing part 8 can only rotate in one direction to switch the side protection mechanism to the unfolded state, and cannot rotate in the opposite direction.

[0100] The third locking mechanism is arranged between the support 2 and the bearing part 8. When the side protection mechanism is in the unfolded state, the third locking mechanism is in the locked state, thereby locking the relative position of the support 2 and the bearing part 8. When the third locking mechanism is unlocked, the bearing part 8 can rotate relative to the support 2, thereby switching the side protection mechanism to the folded state.

[0101] The third locking mechanism comprises a third locking pin 81 fixedly arranged on one of the support 2 and the bearing part 8, and a second locking slot 23 arranged on the other. When the third locking mechanism is in the locked state, the third locking pin 81 cooperates with the second locking slot 23, as shown in Figure 30 When the third locking mechanism is in the unlocked state, the third locking pin 81 is disengaged from the second locking slot 23, as shown in Figure 25 .

[0102] In this embodiment, the second locking slot 23 can be elastically deformed to a certain extent, thereby enabling the third locking pin 81 to enter the second locking slot 23 or disengage from the second locking slot 23.

[0103] The rest is the same as in Embodiment 1.

[0104] When the side protection mechanism is locked in the folded state by the second locking mechanism, the carrier 8 can be kept in the state of approaching the base 3 without locking the positions of the support 2 and the carrier 8 due to the limiting structure between the support 2 and the carrier 8, which makes the structure of the child safety seat simple.

[0105] When the side protection mechanism is converted from the folded state to the unfolded state, after the support 2 is rotated to the position where the side protection mechanism is in the unfolded state, the support 2 drives the carrier 8 to slide as a whole relative to the base 3, so that the convex part 31 is inserted into the concave part 21, i.e. the first locking mechanism is locked, as shown in Figure 31 the carrier 8 is rotated relative to the support 2 until the carrier 8 moves to the position where the side protection mechanism is in the unfolded state, and the second locking mechanism is locked. At this time, the side protection mechanism is in the unfolded state.

[0106] When the side protection mechanism is converted from the unfolded state to the folded state, the carrier 8 is reversely rotated relative to the support 2 to unlock the second locking mechanism until the carrier 8 is rotated relative to the support 2 to the position where the side protection mechanism is in the folded state, as shown in Figure 31 the support 2 drives the carrier 8 to slide as a whole relative to the base 3, so that the convex part 31 is out of the concave part 21, i.e. the first locking mechanism is unlocked; the support 2 and the carrier 8 are rotated as a whole to the direction of approaching the base 3 until the side protection mechanism is in the folded state, and the second locking mechanism is locked.

[0107] Embodiment 4

[0108] In this embodiment, as shown in Figures 32-36 the side protection mechanism can further include a strut assembly connected with the support 2 or the base 3 and the carrier 8, respectively. When the side protection mechanism is in the unfolded state, the strut assembly is erected between the support 2 or the base 3 and the carrier 8 to support the carrier 8, so as to improve the carrying capacity of the carrier 8, make the structural strength of the side protection mechanism better, and improve the buffering and energy absorption effect of the side protection mechanism, as shown in Figure 32 and Figure 33 When the side protection mechanism is in the folded state, the strut assembly is folded between the support 2 or the base 3 and the carrier 8, and approaches the support 2 or the base 3 and the carrier 8, respectively, as shown in Figure 34

[0109] Specifically, as shown in Figures 32-36 ​As shown, in this embodiment, the strut assembly includes a diagonal strut 91, one end of which is rotatably connected to the carrier 8, and the other end of which is rotatably and slidably arranged on the base 3. When the carrier 8 is rotated relative to the support 2 to switch the side protection mechanism between the folded state and the unfolded state, the diagonal strut 91 is caused to rotate and slide relative to the carrier 8 and the base 3, so as to stand between the carrier 8 and the base 3, or to be close to the carrier 8 and the base 3, respectively. Of course, conversely, one end of the diagonal strut 91 can be rotatably connected to the base 3, and the other end of the diagonal strut 91 can be rotatably and slidably arranged on the carrier 8. Or the diagonal strut 91 can be movably connected to the carrier 8 and the support 2.

[0110] The strut assembly further includes a torsion spring 92 arranged between the carrier 8 and the diagonal strut 91 to drive the diagonal strut 91 to automatically rotate away from the carrier 8. The torsion spring 92 can also be replaced by other elastic members.

[0111] Or, in other embodiments, one end of the diagonal strut 91 can be rotatably connected to one of the support 2 or the base 3 and the carrier 8, and the other end of the diagonal strut 91 can be detachably connected to the other of the support 2 or the base 3 and the carrier 8. When the side protection mechanism is in the unfolded state, the two ends of the diagonal strut 91 are connected to the support 2 or the base 3 and the carrier 8, respectively. When the side protection mechanism is in the folded state, the detachable connection between the other end of the diagonal strut 91 and the support 2, the base 3 or the carrier 8 is released, and the diagonal strut 91 is rotated relative to one of the support 2 or the base 3 and the carrier 8 to close to it.

[0112] Of course, when the base 3 is not provided, the diagonal strut 91 can be connected to the side of the headrest 14. The strut assembly is not limited to the structure given above, and other structure forms can also be adopted.

[0113] Embodiment 5

[0114] In this embodiment, the support 2 is slidably arranged on the side of the headrest 14. The support 2 is slidably connected to the headrest 14 in the same manner as in Embodiment 2, and the rest is the same as in Embodiment 3.

[0115] Embodiment 6

[0116] In this embodiment, the support 2 is fixedly connected to the side of the headrest 14, i.e. the headrest 14 is always in a state of extending above the backrest 13, and can only slide up and down above the backrest 13 or be fixed relative to the backrest 13. The carrier 8 can adopt the structure forms of Embodiments 1-3.

[0117] The above examples are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and to implement it, and cannot limit the protection scope of the present application. Any equivalent changes or modifications made according to the spirit and essence of the present application shall be covered within the protection scope of the present application.
