The number of the long grooves 21 is one or two. For example, two long grooves 21 are relatively arranged on the bottom surface of the foot support pad 2, and one long groove 21 corresponds to a row of blocks 5. The foot support pad 2 is fitted with the support plate 3, and each row of blocks 5 is accommodated in the corresponding long groove 21. The blocks 5 in the left row are accommodated in the long groove 21 on the left, and the blocks 5 in the right row are accommodated in the long groove 21 on the right. The number of blocks 5 is set according to the angle adjustment of the foot support pad 2. For example, the number of blocks 5 is five, six, seven or eight, and the blocks 5 in each row are evenly spaced.

[0033] An adjustable car seat safety support structure based on the above structure is used for car seat child safety support. The support plate 3 is slidably set at the lower end of the rear seat 1 of the car, and the foot support pad 2 is rotatably set on the top surface of the support plate 3. The support rod 4 is hinged in the long groove 21 on the bottom surface of the foot support pad 2, and a plurality of blocks 5 are arranged at intervals on the top surface of the support plate 3. When the child is in the car seat, the support plate 3 is pulled out from the support plate cavity of the rear seat 1 of the car, and the support plate 3 is located under the child's footboard. The foot support pad 2 is rotated to adjust the angle of the foot support pad 2 so that the foot support pad 2 is rotated towards the direction close to the child's footboard (away from the support plate 3) until the foot support pad 2 contacts the child's footboard or the shoe under the footboard.

[0035] The stop block 6 prevents the support plate 3 from being pulled out of the rear seat 1. A slot that cooperates with the stop block 6 is provided on the top wall of the support plate cavity. The stop block 6 slides within the corresponding slot, pulling out the support plate 3. The stop block 6 slides along the slot to the front end of the slot. The front wall of the slot blocks the stop block 6, restricting the support plate 3 from further sliding, thereby preventing the support plate 3 from being dislodged from the support plate cavity of the rear seat 1. The support plate 3 is rectangular in shape, with bosses provided along the widthwise side surfaces of the support plate 3. The stop block 6 is provided on the rear end upper surface of the bosses.

[0036] As an implementable method, Figure 3 、 Figure 4As shown, a groove 31 is provided at one end of the bottom of the support plate 3 away from the rear seat 1 of the automobile.

[0037] The groove 31 allows the user to reach into the groove 31 and pull the support plate 3 out of the rear seat 1. The groove 31 is concealed to prevent children from pulling out the support plate 3 at will. To facilitate the user's access to the groove 31, an inwardly concave arcuate groove is provided in the rear seat 1 at a position corresponding to the groove 31.

[0038] As an implementable method, Figure 4 、 Figure 5 As shown, a movable block through hole is provided on the groove wall of the groove 31 at one end away from the rear seat 1 of the car, and a movable block 7 is slidably provided on the movable block through hole, and the movable block 7 is provided with two opposite limiting baffles 71, and the limiting baffles 71 are located on the outside of the movable block through hole, and the end face of the movable block 7 close to the outer end of the movable block through hole is provided with two opposite first extrusion blocks 72, and the top surface and the inner side surface corners of the extrusion end of the two first extrusion blocks 72 are chamfered to form a first extrusion portion, and the support plate 3 is a hollow structural member, and a first guide rod 8 relative to the movable block 7 is provided in the support plate 3, and the movable block 7 is provided with a first guide hole cooperating with the first guide rod 8, and the first guide rod 8 is slidably penetrated in the first guide hole, and two opposite For the first linkage rod 8, the first linkage rod 10 is provided with a second extrusion block 101 that cooperates with the corresponding first extrusion block 72 at one end of the first linkage rod 10 close to the movable block 7, and the top surfaces and outer surface corners of the extrusion ends of the two second extrusion blocks 101 are chamfered to form a second extrusion portion, and a fixed rod 11 is vertically provided at the other end of the first linkage rod 10, and a support block 12 is provided on the outer side wall of the fixed rod 11 away from the end of the first linkage rod 10, and a support block through hole that cooperates with the corresponding support block 12 is provided on the side wall of the end of the support plate 3 away from the first linkage rod 10, and the support block 12 is slidably set in the support block through hole, and two opposite fixed plates 14 are provided in the support plate 3, and a first spring 13 is fixedly provided between the fixed plate 14 and the corresponding fixed rod 11.

[0039] In the initial state, the support plate 3 is located in the support plate cavity of the rear seat 1 of the automobile. The support block 12 extends out of the support block through hole and abuts against the side wall of the support plate cavity of the rear seat 1 of the automobile. There is friction between the support block 12 and the side wall of the support plate cavity, locking the support plate 3 in the support plate cavity of the rear seat 1. When the support plate 3 needs to be pulled out, the user's hand reaches into the groove 31 and presses the movable block 7. The first squeezing block 72 presses down toward the second squeezing block 101, driving the two opposing second squeezing blocks 101 to move simultaneously toward the direction close to the first guide rod 8, driving the two opposing linkage rods 10 to move simultaneously toward the direction close to the first guide rod 8, and driving the fixed rod 11 to move toward the direction close to the fixed plate 14. At the same time, the first spring 13 compresses and stores energy, driving the support block 12 to move toward the direction close to the fixed plate 14. The support block 12 contracts and enters the support block through hole. The support block 12 separates from the side wall of the support plate cavity of the rear seat 1 of the automobile. The support plate 3 is unlocked, and the support block 12 no longer presses against the support plate 3. The side walls of the plate cavity interfere with the block, allowing the support plate 3 to be freely pulled out of the support plate cavity of the rear seat 1 of the car. After the support plate 3 is pulled out, the movable block 7 is released, and the first spring 13 releases the stored energy. The first spring 13 extends and pushes the fixed rod 11 in a direction away from the fixed plate 14. The fixed rod 11 drives the support block 12 in a direction away from the fixed plate 14. The support block 12 extends out of the support block through hole and abuts against the side walls of the support plate cavity of the rear seat 1 of the car, locking the support plate 3. At the same time, the fixed rod 11 drives the linkage rod 10 in a direction away from the first guide rod 8. The second extrusion block 101 pushes up the first extrusion block 72, causing the movable block 7 to reset. A first spring 13 is fixedly arranged between the fixed plate 14 and the corresponding fixed rod 11. The first spring 13 is a compression spring. The first spring 13 resets the fixed rod 11 and the movable block 7 and supports the fixed rod 11. When retracting the support plate 3, simply press the movable block 7, push the support plate 3 into the support plate cavity of the rear seat 1, and release the movable block 7. This is very convenient. The number of first springs 13 is two or four. If there are four first springs 13, two first springs 13 are welded between the fixed plate 14 at the left end and the fixed rod 11, and two first springs 13 are welded between the fixed plate 14 at the right end and the fixed rod 11. The length of the first guide rod 8 is greater than the distance between the movable block through hole and the inner wall of the support plate 3. In the initial state, the distance between the first extrusion block 72 and the linkage rod 10 is greater than or equal to the length of the support block 12 extending out of the support block through hole, and less than or equal to the sum of the length of the support block 12 extending out of the support block through hole and the axial dimension of the support block through hole. The limit baffle 71 blocks the outside of the movable block through hole, limiting the movable block 7 and preventing it from falling into the groove 31 during the reset process.

[0040] As an implementable method, Figure 4As shown, the first guide rod 8 is provided with a second spring 9, and the second spring 9 is located between the support plate 3 and the movable block 7, and the outer diameter of the second spring 9 is larger than the outer diameter of the first guide hole.

[0041] A second spring 9 is arranged between the support plate 3 and the movable block 7. The second spring 9 is a compression spring, which plays a resetting role for the movable block 7. When the movable block 7 is pressed, the second spring 9 compresses and stores energy. When the movable block 7 is released, the second spring 9 releases the stored energy and stretches to lift the movable block 7, so that the movable block 7 is reset.

[0042] As an implementable method, Figure 4 As shown, a second guide rod 15 is provided in the support plate 3, and the fixing plate 14 and the fixing rod 11 are provided with a second guide hole that cooperates with the second guide rod 15. The two ends of the second guide rod 15 respectively pass through the corresponding second guide holes of the fixing plate 14 and the fixing rod 11, and the fixing rod 11 is slidably connected to the second guide rod 15.

[0043] The second guide rod 15 is arranged along the length of the support plate 3 and is arranged perpendicular to the fixed plate 14 and the fixed rod 11. It guides and supports the fixed rod 11, allowing the fixed rod 11 to slide back and forth along the axial direction of the second guide rod 15, ensuring stable linear motion of the fixed rod 11. The number of second guide rods 15 can be one, two, or more. For example, two second guide rods 15 are arranged at intervals within the support plate 3 to provide better guidance. The left end of the second guide rod 15 passes through the second guide holes of the fixed plate 14 and the fixed rod 11 at the left end, respectively, and the right end of the second guide rod 15 passes through the second guide holes of the fixed plate 14 and the fixed rod 11 at the right end, respectively.

[0044] As an implementable method, Figure 4 As shown, two opposing guide blocks 16 are provided in the support plate 3 , and the guide blocks 16 are provided with third guide holes, and the first linkage rod 10 is slidably inserted into the corresponding third guide holes.

[0045] Guide blocks 16 guide and support linkage rod 10, allowing linkage rod 10 to slide back and forth axially along the third guide holes of guide blocks 16, further ensuring stable linear motion of linkage rod 10. There are two or four guide blocks 16, positioned opposite each other on either side of first guide rod 8, with the third guide holes coaxially aligned.

[0046] As an implementable method, Figure 2 、 Figure 4 、 Figure 7 、 Figure 8 As shown, the outer side wall of the support block 12 is provided with an anti-slip structure.

[0047] The anti-skid structure increases the friction between the support block 12 and the rear seat 1 of the car, locks the support block 12 out of the position of the rear seat 1 of the car, and prevents the support block 12 from sliding relatively inside the rear seat 1 of the car. The anti-skid structure is an anti-skid convex point or an anti-skid convex stripe.

[0048] As an implementable method, Figure 8 As shown, the anti-slip structure is vertical stripes arranged at intervals.

[0049] The vertical stripes are evenly spaced, simple in structure, easy to manufacture, perpendicular to the sliding direction of the support block 12 , and have a good fit with the rear seat 1 of the car, thus generating better friction and being able to better lock the support plate 3 .

[0050] As an implementable method, Figure 6 、 Figure 7 As shown, a foot pad 17 is provided on the top surface of the foot support plate 2.

[0051] The foot pad 17 is removably mounted on the top surface of the foot support plate 2, enhancing the child's comfort and facilitating replacement and cleaning. For example, a side guard is provided on the top surface of the foot support plate 2, near one end of the rear seat 1. The side guard and the top surface of the foot support plate 2 form a mounting portion, which has an L-shaped cross-section. The foot pad 17 is placed within the mounting portion, and anti-slip particles are provided on the bottom surface of the foot pad 17.

[0052] The above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with this technical field can easily think of changes or replacements within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
