Description

Technical Field

[0001] The invention relates to the technical field of mechanical engineering, in particular to a child safety seat. Background Art

[0002] A child safety seat is a device designed to provide safety protection for children when riding in a car. Its structure mainly includes the seat body, backrest, headrest, seat belt system, fixing device and other parts. The seat body provides support, the backrest and headrest give the child's body and head comfortable support and disperse the impact force in case of collision. The seat belt system usually adopts a five-point or three-point design, which can effectively restrain the child's body to prevent him / her from being injured in the car due to sudden braking or collision.

[0003] Child safety seats are commonly used in cars. Child safety seats are based on the law of inertia and the buffering principle in physics. When the vehicle collides or brakes suddenly, the child safety seat remains in place with its stable fixing device, and the seat belt tightly holds the child to prevent him / her from continuing to rush forward due to inertia. At the same time, the seat back, headrest and internal buffering material will absorb and disperse the huge energy generated by the collision, minimizing the damage caused by the impact to the child's body, thereby providing key safety protection for children during driving, greatly reducing the risk of serious injury to children in traffic accidents, and is an indispensable and important equipment to ensure the safety of children riding in vehicles.

[0004] The headrests in traditional child safety seats for cars generally adopt a fixed structural model, and the height of the headrest cannot be adaptively adjusted according to the child's height. In actual use scenarios, especially when children are in the growth and development stage, the sizes of various parts of the body change significantly, and this fixed-structure headrest is difficult to meet the actual needs of children. Long-term use of such safety seats will force the child's head to be in an unnatural posture due to the lack of proper support and comfortable placement space, which can easily cause tension and fatigue of the neck muscles, and ultimately cause children to have obvious head discomfort during the ride. This will not only affect the children's riding experience to a certain extent, but also make children resist using safety seats, indirectly reducing the actual usage rate and safety protection effect of child safety seats.

[0038] The worm 64 is driven to rotate by the micro motor 1 62, and the worm 64 is meshed with the worm wheel 66, thereby driving the worm wheel 66 to rotate, and then driving the rotating shaft 67 to rotate, so that the connecting blocks 68 fixed at both ends of the rotating shaft 67 rotate, thereby realizing the angle change of the base 2 2 relative to the base 1 1, and achieving the purpose of adjusting the angle of the backrest 3 of the base 2 2. At the same time, the micro motor 2 63 drives the frame 65 to rotate, and the micro motor 2 63 drives the frame 65 to rotate, thereby driving the rotating shaft 67 to rotate, and the rotating shaft 67 drives the connecting rod to rotate, thereby assisting the rotation direction and angle of the rotating shaft 67, which is conducive to making the angle adjustment more accurate and multi-directional, and realizing the function that children can adjust to a comfortable sitting position according to their own needs, which not only meets the riding needs of children in different scenarios and relieves the fatigue of long-term riding, but also improves the comfort and safety of children riding, provides a better experience for children riding, enhances the practicality and applicability of child safety seats, avoids the discomfort of children sitting due to the fixed angle of the backrest 3, and improves the overall safety protection effect.

[0039] Please see attached Figure 1 and attached Figure 4 The pedal adjustment assembly 7 includes a second fixed column 71, which is fixedly connected to the side of the base 2 2 away from the backrest 3. The fixed column 71 is internally slidably connected with a sliding column 72. A pedal 73 is provided at one end of the sliding column 72 away from the fixed column 71. A bolt 75 is provided at the top of the second fixed column 71. The pedal 73 is internally rotatably connected with a damping rod 74.

Bolt holes 76 are provided on the tops of the second fixed column 71 and the sliding column 72, and the bolt 75 is threadedly connected to the middle of the bolt hole 76.

[0040] By loosening the bolt 75 on the top of the fixing column 71, the restriction on the sliding column 72 is released, so that the sliding column 72 can slide freely inside the fixing column 71, thereby driving the pedal 73 to adjust its position. After the pedal 73 reaches the appropriate position, the bolt 75 is tightened again to fix the pedal 73, so that the pedal 73 can adapt to the leg length requirements of different children, which is conducive to children maintaining a natural and comfortable leg placement state when riding, reducing leg numbness and discomfort caused by improper position of the pedal 73, improving the overall comfort of children riding, optimizing the user experience of the child safety seat, ensuring the comfort experience of children in the car, reducing children's irritability caused by discomfort, and indirectly improving the safety and stability during driving.

[0041] Please see attached Figure 4 and attached Figure 5The storage box opening and closing assembly 8 includes a protrusion 81, which is symmetrically arranged on the inner wall of the base 2, and a storage box 82 is slidably connected inside the base 2. A fixing block 83 is fixedly connected to the bottom of the storage box 82, and a pressing block 84 is rotatably connected to the end of the fixing block 83 away from the storage box 82. A spring piece 85 is arranged between the storage box 82 and the pressing block 84, and an insert block 86 is fixedly connected to the top of the pressing block 84. The storage box 82 is slidably connected to the side of the protrusion 81 away from the base 2, and a slot 87 is provided at the bottom of the protrusion 81. The insert block 86 is slidably connected to the middle of the slot 87, and a handle 88 is fixedly connected to the outside of the storage box 82.

[0042] By pressing the pressing block 84, the pressing block 84 rotates around the connection point with the fixing block 83, thereby compressing the spring sheet 85 and driving the inserting block 86 to disengage from the second slot 87 at the bottom of the protrusion 81, and then the storage box 82 is conveniently and quickly pulled out of the base 2 2 through the handle 88, which is convenient for placing or taking children's items. When closing the storage box 82, the pressing block 84 is released, the spring sheet 85 rebounds, so that the pressing block 84 returns to its original position, and the inserting block 86 is reinserted into the second slot 87 to fix the position of the storage box 82, making the opening and closing operation of the storage box 82 simple and easy, which is conducive to children taking the required items conveniently during the ride, increasing the autonomy and pleasure of children in the car, and improving the children's riding experience. At the same time, it is also convenient for parents to store children's commonly used items and avoid items being scattered in the car, making the car environment more tidy and orderly.

[0043] Please see attached Figure 1 and attached Figure 8 The buffer assembly 9 includes a fixing rod 91, which is arranged on the top of the base 1. The end of the fixing rod 91 away from the base 1 is slidably connected to a fixing rod 2 92, and a compression spring 93 is arranged inside the fixing rod 2 92, which abuts between the fixing rod 91 and the fixing rod 2 92.

[0044] When the vehicle encounters a bumpy road section during driving, the fixed rod 2 92 set will slide inward relative to the fixed rod 1 91 under the action of the impact force. During this process, the compression spring 93 set inside the fixed rod 2 92 will be compressed. The compression spring 93 absorbs and buffers a part of the impact force through its own elastic deformation, so that the energy transmitted to the base 2 is reduced, which is beneficial to provide more reliable safety protection for children when the vehicle is bumpy and unstable, reduces the risk of children's body being injured due to strong impact force, enhances the safety performance of the child safety seat, ensures the safety of children riding in the vehicle, reduces the possibility of serious injury to children due to accidental impact, and effectively improves the riding comfort of the child safety seat.

[0045] Working principle: When the height of the headrest 10 needs to be adjusted, the user holds the handle 57 at one end of the insertion rod 52 and pulls the insertion rod 52 outward to make the insertion rod 52 disengage from the slot 53 on the slider 4. The insertion rod 52 drives the limit block 55 to compress the spring 56, and then the slider 4 slides up and down in the slide groove 54 of the backrest 3 to adjust the headrest 10 to a suitable height position so that the headrest 10 can adapt to the height of the child. After adjustment, release the handle 57, and the insertion rod 52 is reinserted into the corresponding slot 53 under the elastic force of the spring 56, thereby fixing the position of the slider 4 and the headrest 10.

[0046] When it is necessary to adjust the angle of the seat back 3 of the base 2, start the micro motor 1 62 and the micro motor 2 63, the micro motor 1 62 drives the worm 64 to rotate, the worm 64 engages with the worm wheel 66, thereby driving the worm wheel 66 to rotate, the worm wheel 66 drives the rotating shaft 67 to rotate, and then the connecting blocks 68 fixed at both ends of the rotating shaft 67 rotate, so as to realize the change of the angle of the base 2 2 relative to the base 1 1, so as to achieve the purpose of adjusting the angle of the seat back 3, and the frame 65 is driven to rotate by the micro motor 2 63, and the frame 65 can assist in adjusting the rotation direction and angle of the rotating shaft 67, so that the angle adjustment is more precise and multi-directional to meet the different sitting posture requirements of children.

[0047] When the position of the pedal 73 needs to be adjusted, the bolt 75 is loosened so that the bolt 75 is disengaged from the bolt hole 76, allowing the sliding column 72 to slide freely in the fixed column 71. After the pedal 73 is adjusted to a suitable position, the bolt 75 is tightened again so that the bolt 75 passes through the bolt holes 76 on the fixed column 71 and the sliding column 72, thereby fixing the position of the pedal 73. The damping rod 74 inside the pedal 73 can enable the pedal 73 to have a certain angle adjustment function, thereby meeting the usage needs of different children.

[0048] When it is necessary to open the storage box 82, the pressing block 84 is pressed, and the pressing block 84 rotates around the connection point with the fixing block 83, compressing the spring sheet 85, so that the inserting block 86 is disengaged from the second slot 87 at the bottom of the protrusion 81. At this time, the storage box 82 can be pulled out by pulling the handle 88 on the outside of the storage box 82, which is convenient for placing or taking children's items. When closing the storage box 82, by releasing the pressing piece 82, the reaction force of the spring sheet 85 drives the pressing block 84 to move downward and reinsert the inserting block 86 into the second slot 87 to fix the position of the storage box 82.

[0049] When the vehicle is traveling, the fixing rod 2 92 will slide inside the fixing rod 1 91 when it is impacted. At this time, the compression spring 93 is compressed, and the compression spring 93 can absorb and buffer part of the impact force, thereby reducing the energy transmitted to the base 2 2 .

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
