Description

Technical Field

[0001] This utility model relates to the field of children's products technology, specifically to a child safety seat. Background Technology

[0002] Child safety seats are primarily used when children are riding in cars to improve their safety. A typical child safety seat includes a base, a seat assembly mounted on the base, and support legs at the bottom of the base. The seat assembly can move relative to the base to adjust the child safety seat's position. When in use, the support legs extend downwards from the base and support the seat on the car floor to prevent the child safety seat from tipping over. For ease of transport, the support legs can usually be folded down to the bottom of the base when not in use. In existing technology, child safety seats require the support legs to support the base in some situations to improve stability. However, because the support legs can be folded down, users may forget to reposition the support legs when installing the child safety seat in the car, resulting in an unstable installation and potential safety hazards. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a child safety seat that prevents users from forgetting to switch the support leg to the support position.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A child safety seat, comprising: Base; The seat assembly is movably mounted on the base; The support leg is movably mounted on the base, and the support leg has a supporting position that supports the bottom of the base and a folded position that is close to the base; A limiting component includes a limiting member movably disposed on the base. The limiting member has a first position and a second position. When the limiting member is in the first position, the limiting member cooperates with the seat assembly to prevent the seat assembly from moving relative to the base. When the limiting member is in the second position, the limiting member disengages from the seat assembly to allow the seat assembly to move relative to the base. When the support leg is in the supporting position, the limiting member is in the second position; when the support leg is in the folded position, the limiting member is in the first position.

[0005] In some embodiments, when the support leg is in the folded position, the support leg abuts against the limiting member to place the limiting member in a first position.

[0006] In some embodiments, the bottom of the base is provided with a receiving groove. When the support leg is in the supporting position, the support leg is located outside the receiving groove, and the limiting member extends into the receiving groove by a first length. When the support leg is in the folded position, the support leg is received in the receiving groove, and the limiting member is dislodged from the receiving groove, or the limiting member extends into the receiving groove by a second length, the second length being less than the first length.

[0007] In some embodiments, the limiting component further includes an elastic member for driving the limiting member to move from a first position to a second position, one end of the elastic member being disposed on the base and the other end of the elastic member being disposed on the limiting member.

[0008] In some embodiments, the bottom of the seat assembly is provided with a slot, and when the limiting member is in a first position, the limiting member is partially inserted into the slot; when the limiting member is in a second position, the limiting member is completely disengaged from the slot.

[0009] In some embodiments, the seat assembly is rotatably connected to the base via a rotating part, and the slot is provided on one side of the rotating part; The slot is located on the front side of the rotating part.

[0010] In some embodiments, the support leg is rotatably mounted on the base; and / or, the limiting member is slidably mounted on the base.

[0011] In some embodiments, the child safety seat further includes a locking mechanism disposed between the base and the seat assembly to lock the relative position between the two, the locking mechanism having a locked state and an unlocked state, and the seat assembly being movable relative to the base when the support leg is in a supported position and the locking mechanism is in the unlocked state.

[0012] In some embodiments, the locking mechanism includes a locking member movably disposed on one of the base and the seat assembly, and a locking groove disposed on the other and cooperating with the locking member. When the locking mechanism is in a locked state, the locking member is at least partially located in the locking groove; when the locking mechanism is in an unlocked state, the locking member is completely disengaged from the locking groove.

[0013] In some embodiments, the child safety seat further includes an unlocking mechanism connected or cooperating with the locking mechanism to drive the locking mechanism to unlock. The unlocking mechanism includes an unlocking operation member movably disposed on a component in both the base and the seat assembly where the locking member is disposed, and a driving member disposed between the unlocking operation member and the locking member. The driving member is connected or cooperating with the unlocking operation member and the locking member, respectively.

[0014] In some embodiments, the unlocking mechanism is respectively disposed on the left and right sides, and the driving member on each side is connected or cooperates with the corresponding side of the locking member.

[0015] In some embodiments, the seat assembly is rotatably mounted on the base, and the seat assembly rotates relative to the base to give the child safety seat a forward-facing use state and a rear-facing use state; when the limiting member is in a first position, the child safety seat is in the forward-facing use state; when the limiting member is in a second position, the child safety seat is in either the forward-facing use state or the rear-facing use state.

[0016] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: In the child safety seat of this utility model, when the support leg is in the folded position, the seat assembly cannot move relative to the base to adjust the usage state of the child safety seat, so that the child safety seat can only be used in a certain usage state, such as the forward-facing usage state. Only when the support leg is in the supporting position can the seat assembly move relative to the base to adjust the usage state of the child safety seat. For example, the child safety seat can be used both forward-facing and rear-facing. This can avoid forgetting to switch the support leg to the supporting position, thereby improving the stability and safety of the child safety seat during use. Attached Figure Description

The directions perpendicular to the paper are "left" and "right". The above definitions of directions are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] like Figure 1 and Figure 3 As shown, the child safety seat in this embodiment includes a base 1, a seat assembly 2, and a support leg 6.

[0022] The seat assembly 2 is movably mounted on the base 1, and the seat assembly 2 can be adjusted in its usage state relative to the base 1.

[0023] In this embodiment, the seat assembly 2 is rotatably mounted on the base 1 via a rotating part, specifically a rotating shaft extending in the vertical direction. The seat assembly 2 rotates relative to the base 1 around the rotating shaft, allowing the child safety seat to have both forward-facing and rear-facing usage states. When the child safety seat is in the forward-facing usage state, the child's face is forward, i.e., facing the front of the vehicle. When the child safety seat is in the rear-facing usage state, the child's face is backward, i.e., facing the rear of the vehicle.

[0024] The seat assembly 2 may include a connector 21 and a seat housing 22 disposed on the connector 21. The connector 21 is rotatably connected to the base 1 via a pivot.

[0025] The support leg 6 is movably mounted on the base 1, and has a supporting position and a folded position relative to the base 1. When the support leg 6 is in the supporting position, it extends vertically and supports the front bottom of the base 1, as shown below. Figure 1 As shown. When the support leg 6 is in the folded position, the support leg 6 extends in the front-to-back direction, is housed at the bottom of the base 1, and is close to the base 1, as shown. Figure 3 As shown.

[0026] In this embodiment, the support leg 6 is rotatably mounted on the base 1 via a pivot extending in the left-right direction. The support leg 6 rotates back and forth relative to the base 1 around the pivot, allowing the support leg 6 to switch between a supporting position and a folded position.

[0027] The bottom of the base 1 is provided with a receiving groove 11 extending in the front-to-back direction. When the support leg 6 is in the supporting position, the support leg 6 is located outside the receiving groove 11, such as... Figure 1 As shown. When the support leg 6 is in the folded position, the support leg 6 is housed in the receiving groove 11 and does not extend to the bottom of the receiving groove 11. This makes the child safety seat compact in structure, and the folded position of the support leg 6 does not affect the installation of the base 1 on the car seat.

[0028] The child safety seat also includes a locking mechanism disposed between the base 1 and the seat assembly 2 to lock the relative position between the two, thereby locking the child safety seat in various usage positions. The locking mechanism has a locked state and an unlocked state. When the locking mechanism is in the locked state, the seat assembly 2 cannot move relative to the base 1, such as... Figures 1-4 As shown. When the seat assembly 2 needs to be moved relative to the base 1 to adjust the usage state of the child safety seat, the locking mechanism needs to be switched from the locked state to the unlocked state.

[0029] The locking mechanism includes a locking element 3 movably disposed on one of the base 1 and the seat assembly 2, and a locking groove 211 disposed on the other and cooperating with the locking element 3. When the locking mechanism is in the locked state, the locking element 3 is at least partially inserted into the locking groove 211, such as... Figures 1-4 As shown; when the locking mechanism is in the unlocked state, the locking element 3 is completely disengaged from the lock groove 211.

[0030] In this embodiment, the locking member 3 is rotatably mounted on the base 1, and the locking groove 211 is mounted on the connecting member 21, and is respectively located at the front and rear of the connecting member 21. Figures 1-8 As shown. When the locking mechanism locks the child safety seat in the forward-facing position, the front locking groove 211 engages with the locking element 3, as shown. Figures 1-4 As shown. When the locking mechanism locks the child safety seat in the rear-facing position, the rear locking groove 211 engages with the locking element 3.

[0031] Child safety seats also include an unlocking mechanism, which is connected to or cooperates with a locking mechanism so that when the locking mechanism is in a locked state, operating the unlocking mechanism can cause the locking mechanism to unlock.

[0032] like Figure 5 and Figure 6 As shown, the unlocking mechanism includes an unlocking operation component 41 and a driving component 42. The unlocking operation component 41 is movably mounted on the component where the locking component 3 is located in both the base 1 and the seat assembly 2. The driving component 42 is positioned between the unlocking operation component 41 and the locking component 3, and is connected to or cooperates with both the unlocking operation component 41 and the locking component 3 respectively. When the locking mechanism is in the locked state, the unlocking operation component 41 is operated to move it, and the driving component 42 acts on the locking component 3, causing the locking component 3 to move and disengage from the lock groove 211, thereby unlocking the locking mechanism.

[0033] In this embodiment, the unlocking operation element 41 is a button that can be slidably mounted on the base 1. The driving element 42 is a traction cable, with its two ends connected to the unlocking operation element 41 and the locking element 3, respectively. In other embodiments, the driving element may also be a pull rod, with its two ends connected to the unlocking operation element 41 and the locking element 3, respectively.

[0034] In this embodiment, the unlocking mechanisms are respectively located on the left and right sides of the base 1, and the driving members 42 on both sides are connected or cooperate with the corresponding side of the locking member 3. In this way, when the unlocking operation member 41 on either side is operated, the locking member 3 can be driven to move relative to the base 1 by the driving member 42, thereby unlocking the locking mechanism. This makes it very convenient for the operator to operate the unlocking operation member 41 when the operator is located on either side of the child safety seat.

[0035] The child safety seat also includes a reset element (not shown in the figure), which drives the locking mechanism to reset from the unlocked state to the locked state when the unlocking operation element 41 is released. The reset element can be a spring, which can be located between the locking element 3 and the base 1, between the unlocking operation element 41 and the base 1, or simultaneously between the locking element 3 and the base 1 and the unlocking operation element 41 and the base 1.

[0036] The child safety seat also includes a limiting component, which restricts the movement of the seat component 2, thereby limiting the use of the child safety seat and making it usable only in certain situations.

[0037] like Figures 1-4 , Figure 5 and Figure 6As shown, the limiting assembly includes a limiting member 51 movably mounted on the base 1. The limiting member 51 has a first position and a second position relative to the base 1. When the limiting member 51 is in the first position, it cooperates with the seat assembly 2. At this time, even if the locking mechanism is unlocked, the seat assembly 2 cannot move relative to the base 1. Thus, the child safety seat can only be used in a partial usage state, such as... Figure 1 and Figure 2 As shown. When the limiting member 51 is in the second position, the limiting member 51 disengages from the seat assembly 2. At this time, when the locking mechanism is in the unlocked state, the seat assembly 2 can move relative to the base 1, thereby adjusting the usage state of the child safety seat, such as... Figure 3 and Figure 4 As shown.

[0038] In this embodiment, the bottom of the seat assembly 2 is provided with a slot 212, such as... Figures 1-4 , Figure 7 and Figure 8 As shown. When the limiting member 51 is in the first position, the limiting member 51 is partially inserted into the slot 212. Due to the cooperation between the limiting member 51 and the slot 212, the seat assembly 2 cannot rotate relative to the base 1, as shown. Figure 1 and Figure 2 As shown. When the limiting member 51 is in the second position, the limiting member 51 is completely disengaged from the slot 212, as... Figure 3 and Figure 4 As shown.

[0039] When the support leg 6 is in the supported position, the limiting member 51 is in the second position. For the child safety seat in this embodiment, it can be used in either a forward-facing or rear-facing position for older children. When the support leg 6 is in the folded position, the limiting member 51 is in the first position. For the child safety seat in this embodiment, it can only be used in a forward-facing position for older children, and not in a rear-facing position for younger children. For a rear-facing child safety seat, the child safety seat must be switched to a forward-facing position before the support leg 6 can fold. This prevents the support leg 6 from dislodging from the supported position during use, thus improving the safety performance of the child safety seat.

[0040] The slot 212 is located on one side of the pivot that rotatably connects the seat assembly 2 and the base 1. In this embodiment, it is located on the front side of the pivot. Since the slot 212 is only provided on one side of the bottom of the seat assembly 2, when the child safety seat is in the rear-facing position, the support leg 6 cannot be folded due to the obstruction of the limiting member 51. The seat assembly 2 must first be rotated to put the child safety seat in the forward-facing position before the support leg 6 can be folded, thus preventing misuse.

[0041] In this embodiment, when the support leg 6 is in the supporting position, the limiting member 51 extends into the receiving groove 11 by a first length. When the support leg 6 moves relative to the base 1 from the supporting position to the folded position, after the support leg 6 partially enters the receiving groove 11, the support leg 6 and the limiting member 51 abut against each other. As the support leg 6 continues to move towards the folded position, due to the abutting action of the support leg 6, the limiting member 51 is driven to move relative to the base 1, thereby causing the limiting member 51 to gradually disengage from the receiving groove 11 and gradually insert into the slot 212, until the support leg 6 is in the folded position, at which point the limiting member 51 moves to the first position. When the support leg 6 is in the folded position, the support leg 6 still abuts against the limiting member 51, and the limiting member 51 can be completely disengaged from the receiving groove 11, or it can extend into the receiving groove 11 by a second length, the second length being less than the first length.

[0042] like Figures 1-4 , Figure 5 and Figure 6 As shown, the limiting assembly also includes an elastic element 52, which drives the limiting element 51 to move automatically from the first position to the second position. One end of the elastic element 52 is disposed on the base 1, and the other end of the elastic element 52 is disposed on the limiting element 51. When the support leg 6 is in the folded position, the elastic element 52 is in a compressed state. When the support leg 6 is switched to the supporting position and disengaged from the receiving groove 11, the limiting element 51 moves under the elastic force of the elastic element 52 and gradually disengages from the slot 212 and inserts into the receiving groove 11.

[0043] In this embodiment, the limiting member 51 is slidably disposed on the base 1 in the vertical direction.

[0044] 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.
