[0022] This application provides a safety seat for installation into a vehicle safety seat interface. The safety seat includes a seat body, a winding element, a rigid connector, and a flexible connector. The winding element is rotatably mounted on the seat body. The rigid connector is used to connect to the safety seat interface. The flexible connector includes a first connecting portion connected to the rigid connector and a second connecting portion connected to the winding element. The flexible connector is wound or released when the winding element rotates.
[0023] In this application, when installing or removing a child safety seat, the flexible connector can be released by rotating the drive winding element. Since the flexible connector is releasable, the user only needs to place the child safety seat on the vehicle seat and pull out the rigid connector to install or remove the interface between the rigid connector and the child safety seat. There is no need to lift the child safety seat during installation and removal, and the installation and removal process is simple and labor-saving.
[0024] Please combine Figures 1 to 4 The safety seat of this embodiment includes a seat body 1, a rigid connector 2, a flexible connector 3, and a winding element 4. The rigid connector 2 is used to connect to the safety seat interface 8 of a motor vehicle. The flexible connector 3 connects the rigid connector 2 and the winding element 4. The winding element 4 is rotatably mounted on the seat body 1. The winding element 4 is used to release the flexible connector 3 during seat installation or removal, and to wind the flexible connector 3 after installation or removal.
[0025] In this embodiment, the safety seat includes two rigid connectors 2 and two flexible connectors 3. The two flexible connectors 3 are connected to the same winding element 4. By driving the winding element 4, the two flexible connectors 3 can be wound or released simultaneously. Compared to directly pulling the two flexible connectors 3 by hand, using the winding element 4 ensures that the two flexible connectors 3 are wound or released synchronously, ensuring that one side of the safety seat will not tilt forward or backward, thereby improving the installation stability of the safety seat.
[0026] In this embodiment, the child seat interface 8 is an ISOFIX interface, and the flexible connector 3 is a nylon braided strap. In other embodiments, the child seat interface can also be a LATCH (Lower Anchors and Tethers for Children) interface, and the flexible connector can also be an Oxford cloth braided strap, etc.
[0027] Please combine Figure 1 and Figure 2 The seat body 1 includes a base 11, a seat portion 12, and a headrest 13. The base 11 supports the seat portion 12 and the headrest 13. After the child safety seat is installed, the base 11 contacts the seat portion of the vehicle seat and is generally horizontally positioned to support the seat portion 12 and the headrest 13. The seat portion 12 is generally L-shaped and is an integral structure used to support the infant's buttocks, back, and waist. The headrest 13 supports the infant's head. The base 11 includes a lower shell 111 and an upper shell 112 that supports the seat portion 12. The seat body 1 is provided with a rib plate 113 supporting the upper shell 112 and a connecting rod bracket 114 connected to the rib plate. In this embodiment, the rib plate 113 and the connecting rod bracket 114 are an integral structure installed in the base 11. In other embodiments, the rib plate 113 and the connecting rod bracket 114 may also be part of the lower shell 111. The connecting rod bracket 114 also serves to support the upper shell 112. The rib plate 113 and the connecting rod bracket 114 are hollow. In this embodiment, the winding element 4 is disposed inside the base 11. In other embodiments, the winding element 4 may also be disposed in the seat portion 12, or the base 11 and the seat portion 12 may be an integral structure, and the winding element 4 may be disposed in the integral structure.
[0028] The base 11 has a length direction X, a width direction Y, and a thickness direction Z. When installed in a motor vehicle, the length direction X and the width direction Y are two directions in the horizontal plane or two directions in approximately the horizontal plane, and the thickness direction Z is a vertical direction or an approximately vertical direction. "Approximately" can be understood as an angle error within 30 degrees.
[0029] The rigid connector 2 has a first position and a second position. Please refer to... Figure 2 When the rigid connector 2 is in the first position, it is located outside the seat body 1; please refer to Figure 3 When the rigid connector 2 is in the second position, it is at least partially housed within the seat body 1. The first position of the rigid connector 2 corresponds to the released state of the flexible connector 3, at which time the child safety seat is being installed or removed; the second position of the rigid connector 2 corresponds to the state where the child safety seat has been installed into the child safety seat interface 8 or removed from the child safety seat interface 8.
[0030] In this embodiment, the rigid connector 2 includes a mounting part 21 and a connecting rod 22 connected to the mounting part. The mounting part 21 has a bayonet for connecting to the safety seat interface 8, and the connecting rod 22 is connected to the flexible connector 3.
[0031] Please combine Figure 3 and Figure 4 In this embodiment, when the rigid connector 2 is in the first position, the connecting rod 22 is located outside the connecting rod bracket 114; when the rigid connector 2 is in the second position, the connecting rod 22 is accommodated within the connecting rod bracket 114, and one end of the flexible connector 3 passes through the connecting rod bracket 114. In other embodiments, the connecting rod may also be partially accommodated within the connecting rod bracket. When the safety seat is installed in the vehicle's safety seat interface 8, the rigid connector 2 is in the second position, and the side wall of the connecting rod bracket 114 can restrict the connecting rod 22 in the length direction X, thereby restricting the movement of the safety seat in the length direction X and ensuring the stability of the safety seat. In this embodiment, the length of the connecting rod 22 is greater than the length of the mounting portion 21. When the rigid connector 2 is in the second position, it ensures that the connecting rod 22 has sufficient length (dimension in the width direction Y) to be accommodated within the connecting rod bracket 114, further ensuring the stability of the safety seat.
[0032] The flexible connector 3 includes an intermediate connecting portion 31, a first connecting portion 32 connected to the rigid connector 2, and a second connecting portion 33 connected to the winding element 4. The intermediate connecting portion 31 connects the first connecting portion 32 and the second connecting portion 33. When the rigid connector 2 is in the first position, the flexible connector 3 passes through the linkage bracket 114. The flexible connector 3 is wound or released when the winding element 4 rotates. After the flexible connector 3 is released, the user does not need to lift the entire car seat; they can simply pull out the rigid connector 2 to connect the mounting part 21 to the car seat interface 8 or remove the mounting part 21 from the car seat interface 8. The rigid connector 2 switches from the first position to the second position because the flexible connector 3 is wound, which drives the rigid connector 2, thus switching the rigid connector 2 to the second position. Conversely, the rigid connector 2 switches from the second position to the first position because the flexible connector 3 is released.
[0033] In this embodiment, the safety seat also includes a roller 5 rotatably mounted on the seat body 1. The roller 5 is rotatably mounted on the lower shell 111 of the base 11. The roller 5 is collinear with the connecting rod bracket 114, which can be understood as the roller 5 being located on the axis of the connecting rod bracket 114. The roller 5 is used to tension the flexible connector 3 while ensuring that the flexible connector 3 does not contact the inner wall of the connecting rod bracket 114, so as not to increase the resistance to winding or releasing. The flexible connector 3 changes its direction of movement after passing through the roller 5. Optionally, the direction of movement of the flexible connector 3 changes by 90 degrees after passing through the roller.
[0034] Please combine Figure 5 In this embodiment, the winding element 4 is driven to rotate by a drive assembly. The drive assembly includes a power unit 6 and a transmission unit 7. The transmission unit 7 is electrically connected to the power unit 6 and the winding element 4, thereby transmitting the power of the power unit 6 to the winding element 4 to achieve transmission. Optionally, the power unit 6 is a motor, and the transmission unit 7 includes a worm 71 and a worm wheel 72 meshing with the worm 71. The worm 71 is fixed to the output shaft of the power unit 6, and the winding element 4 is fixed to the worm wheel 72. When the power unit 6 rotates clockwise, the winding element 4 releases the flexible connector 3; when the power unit 6 rotates counterclockwise, the winding element 4 winds the flexible connector 3. Of course, in other embodiments, the transmission unit 7 can be a gear transmission structure, a belt transmission mechanism, etc.; the power unit 6 can also directly drive the winding element, that is, the drive assembly only includes the power unit 6.
[0035] The rotation axis of the winding element 4 extends along the thickness direction Z to enable simultaneous winding or unwinding of the two flexible connectors 4. The rotation axis of the power unit 6 extends along the length direction X or the width direction Y, that is, the power unit 6 is arranged along the length direction X or the width direction Y. This is because the thickness direction Z dimension is usually small, and this arrangement can save space and avoid increasing the size of the base 11 in the thickness direction Z due to the arrangement of the power unit 6.
[0036] The safety seat also includes a control panel 10, which is located on the outer surface of the seat portion of the seat body 1 for easy operation. The control panel 10 includes a power button, a winding button, and a release button. The power unit 6 can be powered by the safety seat's internal battery (not shown) or electrically connected to the vehicle's power interface for power supply. The power unit 6 automatically or manually disconnects power when the flexible connector 3 is fully wound or released to prevent it from burning out due to jamming. Optionally, the winding time is determined based on the length of the flexible connector 3 and the winding speed, and the power unit 6 automatically disconnects power after the winding time is reached. At this time, the rigid connector 2 is at least partially located within the seat body 1, and the seat portion 12 rests against the backrest of the vehicle seat. The winding speed can be calculated using the rotational speed of the power unit 6 and the transmission ratio of the transmission unit. Of course, the automatic or manual disconnection of the power unit 6 when the flexible connector 3 is partially wound or released is acceptable as long as it facilitates installation and disassembly.
[0037] In other embodiments, an operating part connected to the winding element and exposed on the outer surface of the seat body can also be provided. The user can directly drive the operating part manually to drive the winding element to rotate, thereby realizing the winding or unwinding of the flexible connector 3.
[0038] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
