Description

Technical Field

[0001] This invention belongs to the technical field of side-impact protection devices, specifically relating to a hidden side-impact protection device for a child safety seat. Background Technology

[0002] A car child safety seat is a seat designed specifically for children of different ages. Installed in a car, it effectively improves the safety of children while traveling. It can be combined with additional devices such as portable cribs, infant carriers, auxiliary seats, and collision protection devices. In the event of a car collision or sudden deceleration, it reduces the impact force on children and restricts their body movement to minimize harm and ensure their safety while traveling.

[0003] In existing technology, child seats are generally equipped with cushioning pads on both sides. The flexibility of the cushioning pads can effectively prevent children from being hit by the hard child seat due to inertia when the vehicle makes a sharp turn, thus providing a good cushioning effect. However, in practice, the cushioning pads are mostly exposed to the outside of the child seat for a long time. Their surface is very easy to accumulate a lot of stains when children eat in the car, which requires caregivers to frequently remove, wash and replace them, which is time-consuming and laborious.

[0004] Therefore, there is a need for a hidden side-impact protection device for child safety seats to solve the problem that the existing cushioning pads are mostly exposed on the child seats for a long time, and their surfaces are very easy to accumulate a lot of dirt when children eat in the car. Summary of the Invention

[0005] The purpose of this invention is to provide a hidden side-impact protection device for child safety seats to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A child safety seat concealed side impact protection device includes a concealed box with one side open, a buffer protective plate vertically disposed outside the opening of the concealed box, and a flip-up concealed component disposed inside the opening of the concealed box;

[0008] The flip-up concealing component includes a flip rod rotatably mounted on the inner wall of the bottom of the concealing box and a flip plate fastened to the flip rod. The end of the flip rod rotatably extends out of the concealing box and is fixed with a rotating cap. The buffer protective plate is detachably mounted on one side of the flip plate.

[0009] It should be noted in the solution that a fixed gear is fastened to the rod above the hidden box on the flipping rod. A supply slide is provided on the side of the fixed gear and is fixedly connected to the top surface of the hidden box perpendicularly. The side of the supply slide facing the fixed gear is open. A fixed tooth block slides in the inner side of the supply slide. One end of the fixed tooth block passes between two adjacent teeth of the fixed gear. A push-pull screw is threaded through the other side of the supply slide and is rotatably connected to the other end of the fixed tooth block.

[0010] It is worth noting that a mounting plate is fixed on the back of the buffer protective plate, and several sockets are fixed at equal intervals on the side of the flip plate. A plug strip that is fixed to the mounting plate is slidably arranged in the inner side of the socket. A movable groove is opened on the inner side wall of the socket, and a positioning plug for locking the plug strip in the inner side of the socket is provided in the movable groove.

[0011] Furthermore, it should be noted that the positioning plug includes a locking block that is slidably disposed in the inner side of the movable groove in the shape of a right-angled trapezoid. One end of the locking block is fixedly connected to the innermost inner wall of the movable groove with a return spring. The plug bar has a fixing hole corresponding to the movable groove. The other end of the locking block passes through the inner side of the fixing hole, and the inclined side of the locking block is distributed upward.

[0012] Preferably, the inner wall of the locking block is provided with a pressure groove with a cross-section of a right trapezoid, and the inner wall of the top of the movable groove is provided with a pressure supply groove that communicates with the pressure groove. A pressing rod is slidably arranged in the pressure supply groove. One end of the pressing rod passes through the pressure groove and is fixed with a pressing ball that abuts against the inner wall of the pressure groove. The other end of the pressing rod passes through the socket and is fixed with a pressure plate.

[0013] Preferably, a tension spring is fitted on the rod body of the extrusion rod located inside the pressure supply groove. One end of the tension spring is fixedly connected to the inner wall of the top of the pressure supply groove, and the other end of the tension spring is fixedly connected to a fixing ring, which is tightly fitted onto the rod body of the extrusion rod.

[0014] Preferably, mounting screws are vertically fixed at the four corners on the other side of the hidden box, and mounting nuts are threaded onto the shafts of the mounting screws.

[0015] Compared with the prior art, the hidden side-impact protection device for child safety seats provided by the present invention has the following beneficial effects:

[0016] (1) By setting up a flip-to-hide component, when a child is eating in the seat, the caregiver in the car only needs to turn a knob to make the flip rod rotate 180 degrees, so that the flip plate can be swapped on both sides and the external buffer protective plate can be turned into the inside of the hidden box to hide it, thereby preventing the buffer protective plate from being contaminated during the child's meal.

[0017] (2) By setting up a socket and a plug, the mounting plate can be slid up and the plug can be slid out from the inside of the socket, so that the mounting plate and the socket can be quickly separated. This replaces the traditional setting of the hidden box and the seat being integrated. It is convenient for manual removal and cleaning of the buffer protection plate when the surface of the buffer protection plate is contaminated. Attached Figure Description

[0025] Please see Figure 1-5 The present invention provides a hidden side impact protection device for a child safety seat, including a hidden box 1 with one side open, a buffer protective plate 3 vertically arranged outside the opening of the hidden box 1, and a flip-up hidden component arranged inside the opening of the hidden box 1.

[0026] The flip-out concealing component includes a flip rod 4 rotatably mounted on the inner wall of the bottom end of the concealing box 1 and a flip plate 5 fastened to the body of the flip rod 4. The end of the flip rod 4 rotatably passes through the concealing box 1 and is fixed with a rotating cap 6. The buffer protective plate 3 is detachably mounted on one side of the flip plate 5.

[0027] By flipping the hidden parts, when the child is eating in the seat, the caregiver in the car only needs to turn the knob to make the flipping rod 4 rotate 180 degrees with the flipping plate 5. In this way, the flipping plate 5 can be switched on both sides, and the external buffer protective plate 3 can be turned into the inside of the hidden box 1 and hidden, thereby preventing the buffer protective plate 3 from being contaminated during the child's meal.

[0028] After the child finishes eating, rotate the rotating cap 6 180 degrees in the opposite direction and operate the flip plate 5 to switch the two sides again. Then, the hidden box 1 can be flipped out of the buffer protection plate 3, so that the buffer protection plate 3 can continue to be used to prevent the child in the seat from side impact.

[0029] Furthermore, such as Figure 2 As shown, it is worth noting that a fixed gear 7 is fastened to the rod body of the flipping rod 4 above the hidden box 1. A supply slide 8 is provided on the side of the fixed gear 7 and is fixedly connected to the top surface of the hidden box 1 perpendicularly. The side of the supply slide 8 facing the fixed gear 7 is open. A fixed tooth block 9 slides in the inner side of the supply slide 8. One end of the fixed tooth block 9 passes between two adjacent teeth of the fixed gear 7. A push-pull screw 10 is threaded through the other side of the supply slide 8 and is rotatably connected to the other end of the fixed tooth block 9.

[0030] After the knob is turned and the cap 6 completes the double-sided rotation of the flip plate 5, the knob is then turned and the push-pull screw 10 is pulled. This causes the push-pull screw 10 to pass through the inner side of the slide block 8 under the thread structure and push the fixed tooth block 9. The fixed tooth block 9 can then be forcefully aligned and inserted between two adjacent teeth of the fixed gear 7. In this way, the fixed gear 7, the flip rod 4 and the flip plate 5 can be effectively locked together, ensuring the stability of the buffer protection plate 3 on the outside of the hidden box 1.

[0031] Furthermore, such as Figure 1 , Figure 4 as well as Figure 5 As shown, it is worth noting that a mounting plate 2 is fixed on the back of the buffer protection plate 3, and several sockets 11 are fixed at equal intervals on the side of the flip plate 5. A plug strip 12 that is fixed to the mounting plate 2 is slidably arranged in the inner side of the socket 11.

[0032] By using the socket 11 and the insert 12, the mounting plate 2 can be slid up and the insert 12 can be slid out from the inside of the socket 11, thus quickly separating the mounting plate 2 from the socket 11. This replaces the traditional design where the hidden box 1 is integrated with the seat, and allows for easy manual removal and cleaning of the buffer protection plate 3 when its surface is contaminated.

[0033] Furthermore, such as Figure 5 As shown, it is worth noting that a movable groove 13 is provided on the inner wall of the socket 11, and a positioning plug for locking the plug 12 in the inner side of the socket 11 is provided in the movable groove 13.

[0034] The positioning plug includes a locking block 14 that is slidably disposed in the inner side of the movable groove 13 in the shape of a right trapezoid. A return spring 16 is fixed between one end of the locking block 14 and the innermost inner wall of the movable groove 13. A fixing hole 15 corresponding to the movable groove 13 is opened on the insert 12. The other end of the locking block 14 passes through the inner side of the fixing hole 15, and the inclined side of the locking block 14 is distributed upward.

[0035] When the insert 12 is aligned with the inside of the socket 11, the insert 12 can pre-contact the inclined edge of the locking block 14 inside the socket 11, causing the locking block 14 to be squeezed and passively contracted inside the movable groove 13 and deformed by compressing the return spring 16. When the insert 12 is fully inserted into the socket 11, the fixing hole 15 can correspond to the movable groove 13. Then, the locking block 14 can be reset and inserted into the fixing hole 15 under the elastic force of the return spring 16, thereby effectively locking the insert 12 and ensuring that the mounting plate 2 and the buffer protection plate 3 are fixedly connected to the socket 11.

[0036] Furthermore, such as Figure 5 As shown, it is worth noting that the inner wall of the locking block 14 is provided with a pressure groove 20 with a cross section in the shape of a right trapezoid. The inner wall of the top of the movable groove 13 is provided with a pressure supply groove 17 that communicates with the pressure groove 20. A pressing rod 18 is slidably arranged in the pressure supply groove 17. One end of the pressing rod 18 is inserted into the pressure groove 20 and a pressing ball 19 that abuts against the inner wall of the pressure groove 20 is fixed thereon. The other end of the pressing rod 18 is inserted out of the socket 11 and a pressure plate 23 is fixed thereon.

[0037] The pressure plate 23 is pressed down, and the pressure rod 18 is forced to carry the pressure ball 19 down and into the inner side of the pressure groove 20. In this way, the pressure ball 19 can squeeze the pressure groove 20 obliquely towards the inner wall during the downward movement, which can effectively form a pulling force on the locking block 14 away from the fixing hole 15, so that the locking block 14 is forced to withdraw from the inner side of the fixing hole 15, thus releasing the fixing effect on the insert 12.

[0038] Furthermore, such as Figure 5 As shown, it is worth noting that a tension spring 22 is sleeved on the rod body of the extrusion rod 18 located inside the pressure supply groove 17. One end of the tension spring 22 is fixedly connected to the inner wall of the top of the pressure supply groove 17, and the other end of the tension spring 22 is fixedly connected to a fixing ring 21. The fixing ring 21 is tightly sleeved on the rod body of the extrusion rod 18.

[0039] When the pressure plate 23 is pressed down, the pressing rod 18 moves down. At the same time, the pressing rod 18 can carry the fixing ring 21 down and stretch the tension spring 22 to deform. In this way, by utilizing the rebound force of the tension spring 22, when the pressure on the pressure plate 23 is manually released, the tension spring 22 can carry the pressing rod 18 and the pressing ball 19 to automatically reset as a whole, which is convenient for secondary use.

[0040] Furthermore, such as Figure 1 As shown, it is worth noting that there are four vertically fixed mounting screws 24 at the four corners on the other side of the hidden box 1, and mounting nuts 25 are threaded onto the rods of the mounting screws 24.

[0041] In use, align the mounting screw 24 with the pre-drilled hole that runs through the side of the seat, and make the hidden box 1 fit tightly against the side of the seat. Then, screw the mounting nut 25 into the mounting screw 24 so that the mounting nut 25 abuts against the seat. In this way, the mounting nut 25 and the mounting screw 24 can effectively fix the hidden box 1 to the side of the seat.

[0042] In summary: By using the flip-to-hide component, when a child is eating in the seat, the caregiver only needs to turn a knob to rotate the flip lever 4, which carries the flip plate 5, 180 degrees. This allows the flip plate 5 to be swapped between the two sides, turning the external buffer protective plate 3 inside the hidden box 1 to prevent it from being contaminated during the child's meal. The mounting plate 2 can be slid up using the socket 11 and insert 12, allowing the insert 12 to slide out from the inside of the socket 11, thus quickly separating the mounting plate 2 from the socket 11. This replaces the traditional design where the hidden box 1 is integrated with the seat, making it convenient for manual removal and cleaning of the buffer protective plate 3 when it becomes contaminated.
