[0007] In some embodiments, when the side protection mechanism is in the second state, the area of ​​the outer side surface of the stop is not less than the cross-sectional area of ​​the support member in the lateral direction.

[0008] In some embodiments, when the side protection mechanism is in the first state, the stop and the support extend in the same direction.

[0009] In some embodiments, the stop block is rotatably connected to the support member, or the stop block is slidably rotatably connected to the support member. The side protection mechanism further includes a limiting structure disposed between the support member and the stop block, such that in the first state, the stop block can only rotate or slide unidirectionally in the direction that causes the side protection mechanism to transition to the second state.

[0010] In some embodiments, the side protection mechanism further includes a base for connecting to the side of the seat body, the support member being movably connected to the base, and the base being provided with a receiving groove; when the side protection mechanism is in a first state, at least the support member is close to the base and is wholly or partially received in the receiving groove; when the side protection mechanism is in a second state, both the support member and the stop are away from the base.

[0011] In some embodiments, the side protection mechanism further includes a first locking mechanism disposed between the base and the support member to lock the relative positions of the support member and the base member when the side protection mechanism is in a second state;

[0012] And / or, the side protection mechanism further includes a second locking mechanism disposed between the support member and the stop block to lock the relative positions of the support member and the stop block when the side protection mechanism is in the second state;

[0013] And / or, the side protection mechanism further includes a third locking mechanism disposed between the support or the stop and the base, so as to lock the relative position of the support or the stop and the base when the side protection mechanism is in the first state;

[0014] And / or, the side protection mechanism further includes an elastic element disposed between the support and the base, such that after the third locking mechanism is unlocked, the support and the stop automatically move away from the base.

[0015] In some embodiments, the support member is rotatably connected to the base, and the first locking mechanism includes a protrusion disposed on one of the base and the support member and a recess disposed on the other, the protrusion and the recess being detachably engaged, and the support member being slidably disposed relative to the base, such that the protrusion and the recess can be engaged or disengaged.

[0016] Alternatively, the support member is slidably connected to the base, and the first locking mechanism includes a first locking pin movably disposed on one of the base and the support member and a first locking groove disposed on the other, wherein the first locking pin and the first locking groove are detachably engaged.

[0020] The child safety seat has a central plane extending in the front-to-back direction. When the side protection mechanism is in the second state, the extension direction of the block is substantially parallel to the central plane, or is inclined relative to the central plane.

[0021] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: The side protection mechanism of the child safety seat of this utility model, by setting an additional stop, can increase the contact area between the side protection mechanism and the car door when the car is involved in a side collision, thereby effectively absorbing the impact energy generated by the side collision, greatly reducing the impact force, and thus better protecting the child's safety.

Detailed Implementation

[0048] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0049] Example 1

[0050] like Figures 1-6As shown, the child safety seat of this utility model includes a seat body and a side protection mechanism disposed on the side of the seat body.

[0051] The seat body includes a base 11 and a seat housing disposed on the base 11. The seat housing includes a seat 12 and a backrest 13. The seat 12 supports the child's buttocks, and the backrest 13 supports the child's back. The backrest 13 is disposed at the rear of the seat 12. The seat body also includes a headrest 14 for supporting the child's head. Preferably, the headrest 14 is slidably disposed on the backrest 13, thereby adjusting the height of the headrest 14 on the backrest 13 so that the child safety seat can be used by children of different ages.

[0052] Side protection mechanisms can be installed on the sides of the base 11, seat 12, backrest 13, or headrest 14. Figures 1-6 The diagram shows that the side protection mechanism is located on the side of the backrest 13.

[0053] The side protection mechanism has a first state and a second state. When the side protection mechanism is not in use, it is in the first state, in which case it is close to the side of the seat body, preventing it from becoming an obstruction inside the vehicle and preventing passengers next to the child safety seat from touching it. It also facilitates storage. Figures 1-3 As shown. When the side protection mechanism is in use, it is in its second state. In this state, the side protection mechanism extends outward from the side of the seat body and supports itself on the outside of the seat body, as shown. Figures 4-6 As shown, in the event of a side impact, the side protection mechanism can buffer the impact energy generated by the collision from the side of the car, thus achieving the purpose of protecting children from the side. Child safety seats have a central plane extending in the front-to-back direction. Here, the inner side refers to the side facing the central plane, and the outer side, conversely, refers to the side facing away from the central plane.

[0054] The side protection mechanism includes a support member 2 and a stop block 31. One end of the stop block 31 is rotatably connected to one end of the support member 3. In this embodiment, one end of the support member 2 is rotatably connected to the side of the seat body, i.e., the side of the backrest 13.

[0055] When the side protection mechanism is in its first operating state, both the support member 2 and the stop block 31 are close to the side of the seat body, i.e., the side of the backrest 13, forming a first angle between the support member 2 and the stop block 31. Figures 1-3 , Figures 7-11As shown. Preferably, the support member 2 and the stop block 31 extend in the same direction, and the outer side of the support member 2 and the outer side of the stop block 31 are both located inside the outer side of the backrest 13; or, the outer side of the support member 2, the outer side of the stop block 31 and the outer side of the backrest 13 are located in the same plane, which makes the child safety seat aesthetically pleasing, and the side protection mechanism will not affect the passenger sitting next to the child safety seat when riding.

[0056] When the side protection mechanism is in the second operating state, both the support member 2 and the stop block 31 extend to the outer side of the side of the seat body, i.e., the side of the backrest 13. The support member 2 and the stop block 31 extend in different directions, forming a second angle between them. The first angle and the second angle are different, such as... Figures 4-6 , Figures 12-16 As shown.

[0057] When the side protection mechanism is in its second operating state, the extension direction of the stop 31 is substantially parallel to the central plane of the child safety seat, or inclined relative to the central plane, preferably with an inclination angle not exceeding 20°. The outer side of the stop 31 is located outside the outer side of the support member 2, or the outer side of the stop 31 and the outer side of the support member 2 are located in the same plane. The area of ​​the outer side of the stop 31 is not less than the cross-sectional area of ​​the support member 2 in the lateral direction. Thus, when a side impact occurs, the impact load first acts on the outer side of the stop 31. Since the area of ​​the outer side of the stop 31 is relatively large, it can increase the contact area between it and the car door, thereby effectively absorbing the impact energy generated by the side impact, greatly reducing the impact force, and thus providing better safety protection for the child.

[0058] By rotating the support member 2 relative to the side of the backrest 13, the stop block 31 can be rotated relative to the support member 2, allowing the side protection mechanism to switch between the first and second states.

[0059] In other embodiments, the stop 31 may also be slidably and rotatably connected to the support 2. Alternatively, the stop 31 may be detachably connected to the support 2.

[0060] The side protection mechanism also includes a limiting structure, which is set between the support member 2 and the stop block 31. Due to the setting of the limiting structure, when the side protection mechanism transitions from the first state to the second state, after the support member 2 drives the stop block 31 to rotate to the set position, the stop block 31 can only rotate in one direction in the direction that causes the side protection mechanism to transition to the second state, and cannot rotate in the opposite direction.

[0061] The side protection mechanism may also include a base 4, which is embedded in the side of the seat body, i.e., the side of the backrest 13, and the support member 2 is rotatably connected to the base 4. In this way, the side protection mechanism can be installed as a whole on the side of the backrest 13, making the installation of the side protection mechanism convenient. Moreover, if the side protection mechanism is damaged, it can be replaced as a whole.

[0062] The base 4 is provided with a receiving groove 42. When the side protection mechanism is in the first state, both the support member 2 and the stop block 31 are close to the base 4, and both the support member 2 and the stop block 31 are fully received in the receiving groove 42; or the support member 2 is fully received in the receiving groove 42, and the stop block 31 is wholly or partially located in the receiving groove 42; or the support member 2 is mostly received in the receiving groove 42, and the stop block 31 is entirely located outside the receiving groove 42, such as... Figure 7 As shown. When the side protection mechanism is in the second state, both the support member 2 and the stop block 31 are dislodged from the receiving groove 42 and moved away from the base 4, as shown. Figure 12 As shown.

[0063] The side protection mechanism may also include a bracing assembly, which is connected to the support member 2 or the base 4 and the stop block 31 respectively. When the side protection mechanism is in the second state, the bracing assembly stands between the support member 2 or the base 4 and the stop block 31 to support the stop block 31, thereby improving the load-bearing capacity of the stop block 31, resulting in better structural strength of the side protection mechanism and improving its buffering and energy absorption effect. Figures 18-22 As shown. When the side protection mechanism is in the first state, the diagonal brace assembly retracts between the support member 2 or base 4 and the stop block 31, and respectively approaches the support member 2 or base 4 and the stop block 31, as shown. Figure 23 As shown.

[0064] Specifically, such as Figures 18-25 As shown, in this embodiment, the diagonal bracing assembly includes a diagonal brace 32. One end of the diagonal brace 32 is rotatably connected to the stop block 31, and the other end of the diagonal brace 32 is rotatably and slidably mounted on the base 4. When the stop block 31 rotates relative to the support member 2, causing the side protection mechanism to switch between a first state and a second state, the diagonal brace 32 can rotate and slide relative to the stop block 31 and the base 4, thereby standing upright between the stop block 31 and the base 4, or approaching the stop block 31 and the base 4 respectively. Conversely, one end of the diagonal brace 32 can also be rotatably connected to the base 4, allowing the other end of the diagonal brace 32 to be rotatably and slidably mounted on the stop block 31. Alternatively, the diagonal brace 32 can be movably connected to the stop block 31 and the support member 2.

[0065] The diagonal brace assembly may also include a torsion spring 33, which is disposed between the stop block 31 and the diagonal brace 32 to drive the diagonal brace 32 to rotate automatically away from the stop block 31. The torsion spring 33 may also be replaced by other elastic elements.

[0066] Alternatively, in other embodiments, one end of the diagonal brace 32 may be rotatably connected to either the support member 2 or the base 4 and the stop block 31, and the other end of the diagonal brace 32 may be detachably connected to the other one of the support member 2 or the base 4 and the stop block 31. When the side protection mechanism is in the second state, both ends of the diagonal brace 32 are connected to the support member 2 or the base 4 and the stop block 31, respectively. When the side protection mechanism is in the first state, the detachable connection between the other end of the diagonal brace 32 and the support member 2, the base 4, or the stop block 31 is disengaged, and the diagonal brace 32 rotates relative to one of the support member 2 or the base 4 and the stop block 31 to approach it.

[0067] Of course, without the base 4, the diagonal brace 32 can be connected to the side of the seat body. The diagonal brace assembly is not limited to the structure given above, and other structural forms can also be adopted.

[0068] The side protection mechanism also includes a first locking mechanism, which is disposed between the base 4 and the support member 2. When the side protection mechanism is in the second state, the first locking mechanism is locked, thereby locking the relative position of the support member 2 and the base 4. When the first locking mechanism is unlocked, the support member 2 can rotate relative to the base 4, thereby changing the side protection mechanism to the first state. Of course, when the side protection mechanism does not include the base 4, the first locking mechanism can be disposed between the side of the backrest 13 and the support member 2.

[0069] The first locking mechanism includes a protrusion 41 on one of the base 4 and the support 2, and a recess 21 on the other. When the first locking mechanism is in the locked state, the protrusion 41 is inserted into the recess 21, as shown below. Figure 16 As shown. When the first locking mechanism is in the unlocked state, the protrusion 41 disengages from the recess 21, as... Figure 11 As shown.

[0070] In this embodiment, the support member 2 can also be slidably disposed relative to the base 4, so that the protrusion 41 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 4, which simplifies the structure of the child safety seat.

[0071] A guide structure is also provided between the support member 2 and the base 4 to guide and limit the sliding of the support member 2 when it slides relative to the base 4 to lock or unlock the first locking mechanism. The guide structure includes a guide post 5 on one of the support member 2 and the base 4, and a guide groove 22 on the other. The guide post 5 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 5 is located at one end of the guide groove 22, such as... Figure 16As shown. When the first locking mechanism is in the unlocked state, the guide post 5 is located at the other end of the guide groove 22, as... Figure 11 As shown.

[0072] The side protection mechanism also includes a second locking mechanism, which is disposed between the support member 2 and the stop block 31. When the side protection mechanism is in the second state, the second locking mechanism is locked, thereby locking the relative positions of the support member 2 and the stop block 31. When the second locking mechanism is unlocked, the stop block 31 can rotate relative to the support member 2, thereby causing the side protection mechanism to switch to the first state.

[0073] The second locking mechanism includes a second locking pin 6 fixedly disposed on one of the support member 2 and the stop block 31, and a second locking groove 23 disposed on the other. When the second locking mechanism is in the locked state, the second locking pin 6 engages with the second locking groove 23, as shown below. Figure 16 As shown. When the second locking mechanism is in the unlocked state, the second locking pin 6 disengages from the second locking groove 23, as... Figure 11 As shown.

[0074] In this embodiment, the second locking groove 23 can undergo a certain degree of elastic deformation, thereby allowing the second locking pin 6 to enter the second locking groove 23 or disengage from the second locking groove 23.

[0075] The side protection mechanism may also include a third locking mechanism, which is disposed between the support member 2 and the base 4. When the side protection mechanism is in the first state, the third locking mechanism is locked, thereby locking the relative positions of the support member 2 and the base 4. When the third locking mechanism is unlocked, the support member 2 can rotate relative to the base 4, thereby changing the side protection mechanism to the second state. Similar to the first locking mechanism, when the side protection mechanism does not include the base 4, the third locking mechanism can be disposed between the side of the backrest 13 and the support member 2.

[0076] In other embodiments, a third locking mechanism may also be disposed between the stop 2 and the base 4.

[0077] In this embodiment, the third locking mechanism adopts a press-type elastic self-locking mechanism, which has a simple structure and is very convenient for locking and unlocking operations. Specifically, it includes a third locking pin 71 and a mating part 72 that detachably engages with the third locking pin 71. When the third locking mechanism is in the locked state, the third locking pin 71 engages with the mating part 72, as follows: Figure 11 As shown. When the third locking mechanism is in the unlocked state, the third locking pin 71 disengages from the mating part 72, as... Figure 16 As shown.

[0078] The side protection mechanism may also include an elastic element 8, which is disposed between the support 2 and the base 4. When the third locking mechanism is unlocked, the support 2 and the stop 31 as a whole can automatically move away from the base 4 under the elastic force of the elastic element 8. That is, after the third locking mechanism is unlocked in the first state, the side protection mechanism can automatically switch to the second state through the elastic force of the elastic element 8, which makes it convenient for the side protection mechanism to switch between the first and second states.

[0079] Of course, the elastic element 8 can also be omitted, and the side protection mechanism can be switched to the second state by manual operation.

[0080] When the side protection mechanism is locked in the first state by the third locking mechanism, due to the limiting structure between the support member 2 and the stop 31, it is not necessary to lock the position of the support member 2 and the stop 31, and the stop 31 can be kept close to the base 4, which makes the structure of the child safety seat simple.

[0081] When the side protection mechanism is not in use, it is locked in the first state by the third locking mechanism, such as... Figures 1-3 , Figures 7-11 As shown.

[0082] When the side protection mechanism transitions from the first state to the second state, pressing the third locking pin 71 unlocks the third locking mechanism. The support member 2 and the stop block 31 then automatically move away from the base 4 under the elastic force of the elastic member 8, until the support member 2 reaches the position where the side protection mechanism is in the second state. This causes the support member 2 to slide relative to the base 4, allowing the protrusion 41 to be inserted into the recess 21, thus locking the first locking mechanism. Figure 17 As shown; rotate the stop block 31 relative to the support member 2 until the stop block 31 moves to the position where the side protection mechanism is in the second state, and the second locking mechanism locks. At this time, the side protection mechanism is in the second state.

[0083] When the diagonal brace assembly is installed, when the stop block 31 and the support member 2 rotate to switch the side protection mechanism to the second state, the diagonal brace rod 32 will rotate, as shown below. Figure 24 and Figure 25 As shown, when the stop block 31 and the support member 2 are rotated into position, the diagonal brace 32 stands between the base 4 and the stop block 31.

[0084] When the side protection mechanism transitions from the second state to the first state, the stop block 31 rotates in the opposite direction relative to the support member 2, thereby unlocking the second locking mechanism, until the stop block 31 rotates relative to the support member 2 to the position where the side protection mechanism is in the first state. Figure 17As shown; the support member 2 drives the stop block 31 to slide relative to the base 4, thereby causing the protrusion 41 to disengage from the recess 21, and the first locking mechanism is unlocked; the support member 2 and the stop block 31 are rotated together in the direction of approaching the base 4 until the side protection mechanism is in the first state, and the third locking mechanism is locked.

[0085] When diagonal bracing components are installed, such as Figure 24 and Figure 25 As shown, when the stop block 31 rotates relative to the support member 2 to switch the side protection mechanism to the first state, it drives the diagonal brace 32 to rotate; when the stop block 31 rotates to a certain angle, the support member 2 rotates relative to the base 4 and moves closer to it, so that the stop block 31 and the diagonal brace 32 continue to rotate and move closer to the base 4 until the side protection mechanism is in the first state.

[0086] Example 2

[0087] In this embodiment, the support member 2 is slidably disposed on the side of the seat body, i.e., the side of the backrest 13. Specifically, the support member 2 is slidably connected to the base 4, and the receiving groove 42 on the base 4 extends in the left-right direction. When the side protection mechanism is in the first state, both the support member 2 and the stop 31 extend in the left-right direction, thereby retracting into the receiving groove 42 of the base 4. When the side protection mechanism transitions from the first state to the second state, the support member 2 and the stop 31 slide outward toward the outside of the child safety seat, thereby extending out of the receiving groove 42 of the base 4 and standing upright on the outside of the side of the seat body.

[0088] In this embodiment, the first locking mechanism includes a first locking pin movably disposed on one of the base 4 and the support member 2, and a first locking groove disposed on the other. When the first locking mechanism is in the locked state, the first locking pin is inserted into the first locking groove. When the first locking mechanism is in the unlocked state, the first locking pin is disengaged from the first locking groove.

[0089] Multiple first locking grooves can be provided at intervals along the sliding direction of the support member 2 relative to the base 4, so that the support member 2 can extend to different positions on the side of the backrest 13, thereby allowing the side protection mechanism to be adjusted in multiple positions. This allows the side protection mechanism to be placed in a suitable position according to the distance between the child safety seat and the car door, achieving a better side protection effect while ensuring installation.

[0090] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
