Description

Technical Field

[0001] This utility model relates to the field of child safety seats, and more particularly to a rotating child safety seat for automobiles. Background Technology

[0002] Child safety seats are fixed to motor vehicles and consist of a child safety protection system with ISOFIX-connected seat belts or flexible components, adjustment mechanisms, accessories, etc. In the event of a car collision or sudden deceleration, they can reduce the impact force on children and restrict their body movement, thereby mitigating their injuries.

[0003] However, traditional car seats can only be "suspended in multiple positions" and cannot be fixed at any angle. Furthermore, the seat may not be able to be stably fixed when rotated to a specific angle due to insufficient strength of the locking mechanism. For example, when the vehicle encounters a bumpy road, the seat may automatically slide from the 90° suspension state to other angles, causing the child's sitting position to shift and the seat belt restraint to fail.

[0004] Therefore, it is necessary to provide a car child swivel safety seat to solve the above-mentioned technical problems. Utility Model Content

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] First Embodiment

[0029] Please refer to the following: Figure 1 and Figure 2 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a car child rotating safety seat provided by this utility model; Figure 2 for Figure 1 The diagram shows the internal structure of the base. A child car seat with rotating base includes: a main body 1, the main body 1 including a swivel chair 11, and a base 12 mounted on the bottom of the swivel chair 11;

[0030] Rotating mechanism 2, the rotating mechanism 2 includes planetary gear 22, the planetary gear 22 is installed inside the base 12;

[0031] Transmission mechanism 3, the transmission mechanism 3 includes brake pad 31, the brake pad 31 is used to prevent the rotation mechanism 2 from rotating;

[0032] The fixing mechanism 4 includes a toothed plate 41, which is installed inside the base 12.

[0033] The main frame of the swivel chair 11 is composed of high-strength engineering plastic and a metal frame. The headrest, side impact protection area and backrest are filled with expanded polypropylene foam. The surface fabric is made of polyester fiber, nylon, etc. The base 12 bears the weight of the upper part of the base 12 and the weight of the child, ensuring that it does not deform after installation. It is made of high-strength engineering plastic. The function of the rotating mechanism 2 is to drive the swivel chair 11 to rotate. There are multiple planetary gears 22. A gear ring is installed on the inner surface of the base 12. The planetary gears 22 are meshed and connected to the inner surface of the gear ring. There are multiple planetary gears 22, which can rotate on their own axis and rotate in a circle inside the base 12. The function of the transmission mechanism 3 is to connect the transmission to fix the rotating mechanism 2. There are multiple brake pads 31, which can be semi-metallic brake pads, low-metallic brake pads and ceramic brake pads, etc., preferably low-metallic brake pads. The function of the fixing mechanism 4 is to fix the rotating mechanism 2 through the transmission. There are two toothed plates 41, each of which is an arc-shaped block with teeth arrayed on one end of its surface.

[0034] The sun gear 21 is movably mounted inside the base 12, the planetary gear 22 is movably connected to the outer surface of the sun gear 21, and the planetary support 23 is movably connected to the top of the planetary gear 22.

[0035] The sun gear 21 is rotatably connected inside the base 12, and multiple planetary gears 22 are meshed with the outer surface of the sun gear 21. Each planetary gear 22 has a fixed shaft on its top, which is rotatably connected to the bottom surface of the planetary support 23. Thus, when the planetary support 23 rotates, it provides thrust to the planetary gears 22 through the shaft connection, and through meshing with the ring gear and the sun gear 21, it provides rotational and circumferential force to the planetary gears 22, as well as rotational force to the sun gear 21.

[0036] An elastic element 32 is connected to the surface of the brake pad 31, and the elastic element 32 is used to push the brake pad 31 to be connected to the surface of the sun gear 21.

[0037] The elastic element 32 can be a spring telescopic rod or a spring slide rod, preferably a spring slide rod. The bottom of the slide rod is fixedly connected to the top of the brake pad 31, and the top slides through the surface of the planetary support 23 and is fixedly connected to the surface of the connecting frame 33.

[0038] The top of the elastic member 32 is connected to the connecting frame 33, and the top of the planetary support 23 is fixedly connected to the limiting member 34, which is used to limit the movement of the connecting frame 33.

[0039] The connecting frame 33 is a circular sleeve that is slidably embedded inside the limiting member 34 and simultaneously slidably sleeved on the outer surface of the limiting member 34. Multiple plates are fixedly connected to the outer surface of the circular sleeve. The top of the sliding rod of the multiple elastic members 32 is fixedly connected to the other end of the connecting plate. By limiting the connecting frame 33 through the limiting member 34, the connecting frame 33 can drive the elastic members 32 and the brake pad 31 to move up and down. And by the elastic force of the elastic members 32, the brake pad 31 stops itself.

[0040] A meshing member 42 is fixedly connected to the inner surface of the base 12. The meshing member 42 is connected to the toothed plate 41 for fixing the rotating mechanism 2. A push-pull rod 43 is connected to the top of the toothed plate 41, and the other end of the push-pull rod 43 is movably connected to the surface of the connecting frame 33.

[0041] There are two meshing components 42, which can be an internal gear ring and a rack, preferably an internal gear ring. It is fixedly connected to the top of the meshing gear ring on the surface of the planetary gear 22. Two sliders are provided on the surface of the planetary support 23. A slider is fixedly connected to the top of each of the two tooth plates 41. The two sliders are slidably embedded in the interior of the two grooves. One end of each of the two push rods 43 is rotatably connected to the top of the two sliders, and the other end is rotatably connected to the surface of the connecting frame 33. In the natural state, the connecting frame 33 is in the lowest state. One end of each of the two push rods 43 pushes the two tooth plates 41, so that one end of their teeth meshes with the tooth surface of the meshing component 42. The planetary support 23 is then fixed.

[0042] The top of the limiting member 34 is provided with a connecting mechanism 5, which includes a connecting plate 51 and a fixing hole 52. The connecting plate 51 is fixedly connected to the top of the connecting frame 33, and the fixing hole 52 is formed on the surface of the connecting plate 51.

[0043] The top of the elastic element 32 moves through the top surface of the base 12 and is embedded in the outer surface of the top of the base 12. The connecting plate 51 is fixedly connected to the top of the elastic element 32. The surface of the elastic element 32 has multiple threaded holes, and bolts can be threaded through the fixing holes 52 to the bottom of the swivel chair 11, thus realizing the connection and fixation between the swivel chair 11 and the connecting plate 51.

[0044] The working principle of the car child rotating safety seat provided by this utility model is as follows:

[0045] When the angle of the swivel chair 11 needs to be adjusted, pull the swivel chair 11 upwards. The connecting plate 51, threaded to the bottom of the swivel chair 11, causes the elastic element 32 to move upwards. During this process, the connecting frame 33, connected to the elastic element 32, causes the brake pad 31 and the other end of the push-pull rod 43 to move upwards. The brake pad 31 then disengages from the surface of the sun gear 21. The push-pull rod 43, limited by the connection between the toothed plate 41 and the planetary support 23, applies an inward pulling force to the toothed plate 41, causing the two toothed plates 41 to move relative to each other and disengage from the meshing element 42. At this point, the sun gear 21 and the planetary support 23 lose their fixing force. Then, rotate the swivel chair 11, and the connecting plate 51... The rotating connecting frame 33 rotates, which in turn pushes the planetary support 23 to drive multiple planetary gears 22 to rotate in a circular motion. At the same time, the connecting frame 33 meshes with the sun gear 21 and rotates, driving the sun gear 21 to rotate. After rotating to a suitable angle, the swivel chair 11 is released. Under the action of gravity and the elastic force of the elastic element 32, the connecting frame 33 drives the other end of the push-pull rod 43 to move downward. The push-pull rod 43 then pushes the two toothed plates 41 to move towards each other and mesh with the surface of the meshing element 42. Under the action of gravity and elastic force, the brake pad 31 tightly squeezes the sun gear 21. Thus, the swivel chair 11 is fixed by the meshing connection of the toothed plates 41 and the meshing element 42 and the damping of the sun gear 21 by the brake pad 31.

[0046] Compared with related technologies, the car child rotating safety seat provided by this utility model has the following beneficial effects:

[0047] This utility model provides a rotating car seat for children. By pulling the swivel chair 11 upward, the toothed plate 41 is moved through the transmission mechanism 3. The rotating mechanism 2 loses its fixing force, thereby allowing the base 12 to be adjusted to any angle and fixed by the fixing mechanism 4. This achieves suspension at any angle and improves the stability of the base 12.

[0048] Second Embodiment

[0050] Specifically, the second embodiment of this application provides a different car child swivel safety seat in that the swivel seat 11 has a heating mechanism 6 inside, the heating mechanism 6 includes a temperature sensor 61, the temperature sensor 61 is fixedly installed inside the swivel seat 11, the heater 62 is fixedly installed at the bottom of the swivel seat 11, and the heat insulation pad 63 is fixedly connected to the top of the heater 62.

[0051] The surface of the heat insulation pad 63 has multiple vent holes. The heat generated by the heater 62 is transferred to the surface of the heat insulation pad 63 and flows through the vent holes.

[0052] The working principle of the car child rotating safety seat provided by this utility model is as follows:

[0053] When the temperature sensor 61 senses that the temperature of the swivel chair 11 is low, it sends a signal to control the heater 62 to start heating. The heat insulation pad 63 prevents the heater 62 from directly contacting the skin and transfers heat.

[0054] Compared with related technologies, the car child rotating safety seat provided by this utility model has the following beneficial effects:

[0055] This invention provides a car child swivel safety seat. The temperature sensor 61 senses the temperature and controls the heater 62 to heat the bottom of the swivel seat 11, increasing the child's comfort.
