Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0042] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0043] Please refer to Figures 1-11 The support base 100 and child safety seat provided in the embodiments of the present invention can solve the above problems, and will be described in detail below.

[0044] refer to Figures 1-3 The support base 100 includes a base 110, a fixed frame 120, an adjusting member 130, and an anti-tipping frame 140; wherein, the fixed frame 120 and the adjusting member 130 are disposed on the base 110, the anti-tipping frame 140 is rotatably connected to the fixed frame 120, the adjusting member 130 is connected to the anti-tipping frame 140, and pulls the anti-tipping frame 140 to rotate relative to the fixed frame 120.

[0045] In the above technical solution, the anti-rollover frame 140 can be rotated by the adjusting component 130 during use, so that the relative angle between the anti-rollover frame 140, the fixed frame 120 and the seat 110 changes. When the seat 110 is placed on the seat cushion of the car seat 200, the anti-rollover frame 140 can fit against the back of the car seat 200 to avoid shaking during use and prevent affecting the safety of use.

[0046] refer to Figures 3-8 The fixed frame 120 is provided with a first through hole 121 and a second through hole 122 at intervals, and the anti-tipping frame 140 is provided with a third through hole 141 and a fourth through hole 142 at intervals. Fasteners are movably provided for the first through hole 121 and the third through hole 141, and for the second through hole 122 and the fourth through hole 142. The anti-tipping frame 140 is used to rotate along the fasteners connecting the first through hole 121 and the third through hole 141.

[0047] In the above technical solution, fasteners are movably installed in the corresponding through holes on the anti-rollover frame 140 and the fixed frame 120. On the one hand, the anti-rollover frame 140 and the fixed frame 120 are connected. On the other hand, the movable connection allows the anti-rollover frame 140 to rotate relative to the fixed frame 120. The relative rotation of the two allows the relative angle between the anti-rollover frame 140 and the seat 110 to change, which facilitates the anti-rollover frame 140 to fit against the backrest of the car seat 200 with different tilt angles.

[0048] Specifically, during the fastener connection process, the outer diameter of the rod segment of the fastener located inside the through hole is smaller than the inner diameter of the through hole, allowing the rod end to move within the through hole; while the outer diameter of the head of the fastener located outside the through hole is larger than the minimum inner diameter of the corresponding through hole, preventing the fastener from easily falling out of the through hole and ensuring the connection performance of the anti-tipping frame 140 and the fixing frame 120.

[0049] refer to Figure 4 The third through hole 141 is elongated, and the elongated extension direction of the third through hole 141 is consistent with the extension direction of the first through hole 121 to the second through hole 122.

[0050] In the above technical solution, by providing a long strip-shaped third through hole 141 on the anti-tipping frame 140, when the anti-tipping frame 140 needs to rotate relative to the fixed frame 120, the relative position of the fastener and the third through hole 141 can change, thereby avoiding obstruction to the rotation of the anti-tipping frame 140 and the fixed frame 120.

[0051] refer to Figure 6 The inner wall of the second through hole 122 is provided with a partition 123, which is used to divide the inner cavity of the second through hole 122 into at least two limiting cavities 124.

[0052] In the above technical solution, by setting a partition 123 to form a limiting cavity 124, the fasteners connecting the fourth through hole 142 and the second through hole 122 can be fixed in the limiting cavity 124 by the limiting effect of the partition 123 when no external force is applied; when subjected to a certain external force, the fasteners connecting the fourth through hole 142 and the second through hole 122 can be moved over the partition 123 to other limiting cavities 124.

[0053] refer to Figure 2 and Figure 7 The support base 100 also includes a fixing joint 150 and an adjusting member 130. The fixing joint 150 is connected to the seat body 110 and is used to connect to the car seat 200.

[0054] The adjusting member 130 includes a locking member 131, a pressing member 132, and a supporting member 133. The supporting member 133 is disposed on the base 110. The locking member 131 and the pressing member 132 are both disposed on the supporting member 133. The locking member 131 is connected to the fixed joint 150, and the pressing member 132 is connected to the anti-tipping frame 140. The locking member 131 is used to lock or unlock the pressing member 132.

[0055] In the above technical solution, when the fixed connector 150 is connected to the car seat 200, the locking member 131 can be pulled to move, so that the locking member 131 unlocks the push member 132. The operator can press the push member 132, and the push member 132 drives the anti-rollover frame 140 to move.

[0056] refer to Figures 9-11 The locking member 131 includes a locking lead wire 1311 and a locking slider 1312. The locking lead wire 1311 is connected between the fixed joint 150 and the locking slider 1312. The support member 133 has a locking groove 1331. The locking slider 1312 is slidably disposed in the locking groove 1331. The locking slider 1312 is used to lock or unlock the pusher 132.

[0057] In the above technical solution, the fixed joint 150 can drive the locking slider 1312 to move through the locking lead wire 1311, and the support member 133 is provided with a locking groove 1331 to guide and limit the movement of the locking slider 1312.

[0058] In this embodiment, the locking groove 1331 is perpendicular to the extension direction of the support member 133, while the extension direction of the pusher member 132 is consistent with the extension direction of the support member 133.

[0059] In other embodiments, the extending direction of the locking groove 1331 and the extending direction of the support member 133 may also have an angle, the angle range of which is 45° to 135°. The specific angle can also be 45°, 60°, 75°, 105°, 120°, or 135°, and the specific degree is not limited.

[0060] Optionally, the locking member 131 further includes a first abutment 1313 and a first spring 1314, with the locking lead wire 1311 passing through the first abutment 1313 and the first spring 1314 disposed between the first abutment 1313 and the locking slider 1312.

[0061] In the above technical solution, a first spring 1314 is provided between the first abutment block 1313 and the locking slider 1312, so that the first spring 1314 can provide a certain supporting force for the movement of the locking slider 1312. When the fixed joint 150 is connected to the car seat 200, it can drive the locking slider 1312 to compress the first spring 1314, so that the pusher 132 is in the unlocked state.

[0062] Furthermore, a release switch is provided on the fixed connector 150. By pressing this button 1321, the locking lead wire 1311 is no longer pulled by the fixed connector 150, and the locking slider 1312 can be reset and moved under the elastic tension of the first spring 1314, so that the pusher 132 is in the locked state.

[0063] Optionally, the actuating member 132 includes a button 1321, a movable block 1322, and an actuating wire 1323 connected in sequence. The support member 133 has a movable groove 1332. The movable block 1322 is slidably disposed in the movable groove 1332. The actuating wire 1323 is connected to the anti-tipping frame 140. The locking member 131 is used to lock or unlock the movable block 1322.

[0064] In the above technical solution, the operator can move the movable block 1322 by pressing the button 1321, and drive the anti-tipping frame 140 to move by pressing the lead wire 1323.

[0065] In addition, the actuating member 132 also includes a second spring 1324, which is connected between the movable block 1322 and the support member 133. The second spring 1324 is used to drive the movable block 1322 to reset when there is no external force acting on the movable block 1322.

[0066] Specifically, when the movable block 1322 is in the unlocked state, pressing the button 1321 can move the anti-tipping frame 140 by pressing the guide wire 1323, allowing the fasteners connecting the fourth through hole 142 and the second through hole 122 to move over the partition 123 into other limiting cavities 124, thereby adjusting the relative angle between the anti-tipping frame 140 and the base 110. When the movable block 1322 is in the locked state, the locking slider 1312 will limit the movable block 1322, preventing the movable block 1322 from pulling the anti-tipping frame 140 to move by pressing the guide wire 1323.

[0067] Optionally, the support base 100 further includes a first tension spring 160 and a second tension spring 170, both of which are connected between the anti-tipping frame 140 and the fixed frame 120. The extension direction of the first tension spring 160 is consistent with the extension direction of the anti-tipping frame 140, and the extension direction of the second tension spring 170 is consistent with the extension direction of the fixed frame 120.

[0068] In the above technical solution, the first tension spring 160 is used to provide tension to the anti-tipping frame 140. When the fastener connecting the fourth through hole 142 and the second through hole 122 is located outside the limiting cavity 124, the fastener can be moved back into the limiting cavity 124 under the action of the first tension spring 160. The second tension spring 170 is used to provide tension to the anti-tipping frame 140 to rotate towards the fixed frame 120. When the fastener connecting the fourth through hole 142 and the second through hole 122 moves from the limiting cavity 124 near the seat 110 to the limiting cavity 124 away from the seat 110, that is, when the relative inclination between the anti-tipping frame 140 and the seat 110 is greater, it will overcome the tension provided by the second tension spring 170 to the anti-tipping frame 140.

[0069] It is worth noting that the support base 100 also includes a cover 180, which is connected to the upper side of the base body 110 and can provide partial shielding and protection for the fixing frame 120 and the adjusting component 130. The button 1321 is located on the outside of the cover 180 and the base body 110, making it convenient for the operator to press and control.

[0070] Specifically, actual crash tests have shown that increasing the relative angle between the rollover brace 140 and the seat 110 and decreasing the gap between the rollover brace 140 and the backrest of the car seat 200 can reduce the injury to children during a collision by about 50%. See the table below for specific data:

[0071]

[0072] Here, rear refers to the direction of the collision originating from the rear of the vehicle equipped with the child safety seat; speed refers to the instantaneous velocity at the time of the collision; sled acc is the energy generated by the collision equipment; chest acc is the chest acceleration generated at the time of the collision, which can be used to measure chest injuries; head acc is the head acceleration generated at the time of the collision, which can be used to measure head injuries; and HPC is a parameter describing head injuries.

[0073] An embodiment of the present invention also provides a child safety seat, including the aforementioned support base 100, a seat cushion, and a seat belt. The seat cushion is connected to the upper side of the seat cover 180 and is used to directly contact the child and provide support. The seat belt is connected to the seat cover 180 and passes through the seat cushion, serving to safely restrain the child. Furthermore, the child safety seat may also include a support column, the top section of which is connected to the seat cover 180 or the seat body 110, and the bottom end of the support column contacts the rear floor of the vehicle, thereby increasing support stability.

[0074] The child safety seat includes a support base 100, which has all the functions of a support base 100. During use, it can ensure that it fits snugly against the back of the car seat 200, avoiding gaps, reducing shaking, and thus improving safety.

[0075] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
