Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a child safety seat with a cushioning structure. Background Technology

[0002] A child safety seat is a seat specifically designed for children of different ages (or weights), installed in a car, and effectively improves children's safety while traveling in a vehicle. The main function of a child safety seat is to reduce the impact force on children and restrict their body movement in the event of a collision or sudden deceleration, thereby ensuring their safety while traveling in a car. Specifically, child safety seats can protect children in the following situations:

[0003] Forward collision or emergency braking: Child safety seats effectively prevent children's bodies from moving forward rapidly, avoiding secondary collisions and preventing forward sliding due to poor restraint system positioning. Side collision: The backrest and headrest side wings effectively protect the child's torso and head. Rear collision: The backrest and headrest support the child's torso and head, preventing neck injuries. Rollover: The child's body and restraint system should only shift slightly, and the child must not become loose. When a child is sleeping: The seat side wings ensure the child's body does not tilt severely, preventing injury in a collision. Furthermore, child safety seats prevent children from moving around inside the vehicle and accidentally opening doors or windows, potentially falling out.

[0004] In conclusion, child safety seats are an indispensable child safety protection device in cars, and are of great significance in ensuring the safety of children while traveling in vehicles.

[0005] However, with societal development and the increasing emphasis on children's safety during travel, existing technologies are not always practically applicable. Given the prevalence of traffic accidents, child safety seats have become crucial equipment for ensuring children's safety while traveling in vehicles. However, some existing child safety seats lack sufficient cushioning performance, and the powerful impact during collisions or emergency braking can easily injure children. Utility Model Content

[0006] The purpose of this invention is to provide a child safety seat with a cushioning structure to address the issue raised in the background art, which highlights the increasing importance placed on children's safety during travel as society develops. Given the frequent traffic accidents, child safety seats have become crucial equipment for ensuring children's safety while traveling. However, some existing child safety seats lack sufficient cushioning performance, and the powerful impact during a collision or emergency braking can easily cause injury to children.

[0007] To achieve the above objectives, this utility model provides the following technical solution: including a child safety seat body and a mounting base for installation inside a car;

[0008] The child safety seat body has a buffer pad fixedly installed inside the front end of the main body. The upper rear side of the child safety seat body has an installation strip fixedly installed. The front end of the installation strip has a limit straight slide groove. The middle of the limit straight slide groove is rotatably connected to an adjusting screw through a rotating shaft. The outer curved surface of the side end of the adjusting screw is threaded with a locking ring for locking and tightening the adjusting screw. The outer curved surface of both ends of the adjusting screw is threaded with a slider. The front end of the slider is fixedly installed with an extension arm. The inner side of the extension arm is fixedly installed with a buffer airbag for cushioning and protecting the child's head and neck.

[0009] A hydraulic control cylinder for controlling the delivery of hydraulic oil is fixedly installed at the bottom of the mounting base. A hydraulic buffer telescopic rod is fixedly installed on the front and rear sides of the upper end of the mounting base. A support frame is fixedly installed on the outer telescopic part of the hydraulic buffer telescopic rod. A pressure sensor for controlling the unlocking hydraulic control cylinder is fixedly installed in the middle of the lower end of the child safety seat body. Hydraulic communication ports are fixedly connected to the inner sides of the front and rear ends of the hydraulic buffer telescopic rod.

[0010] Preferably, the cushioning pad is composed of an inner layer, a middle layer and an outer layer of cushioning materials. The inner layer is made of high-elasticity memory foam, the middle layer is a honeycomb rubber pad, and the outer layer is wrapped with soft and wear-resistant environmentally friendly fabric.

[0011] Preferably, the front end of the limiting straight slide groove passes through the upper end of the child safety seat body, the two ends of the adjusting screw have opposite external curved thread orientations, and a knob for rotating the adjusting screw is fixedly installed on the side end of the adjusting screw.

[0012] Preferably, the slider is movably connected to the inner wall of the limiting straight slide groove.

[0013] Preferably, there are four hydraulic buffer telescopic rods, with two hydraulic buffer telescopic rods forming a group, and the two groups of hydraulic buffer telescopic rods are symmetrically distributed on the front and rear sides of the upper end of the mounting base.

[0014] Preferably, the upper end of the support frame is fixedly installed on the front and rear sides of the lower end of the child safety seat body.

[0015] Preferably, the hydraulic connection port is connected to the hydraulic control cylinder via a pipe.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] When this utility model is involved in a collision, the pressure sensor fixedly installed in the middle of the lower end of the child safety seat body will quickly sense the impact force and trigger the unlocking hydraulic control cylinder. When the hydraulic control cylinder is triggered to unlock, it will release the hydraulic oil inside the hydraulic buffer telescopic rod through the hydraulic connection port. When the hydraulic oil inside the hydraulic buffer telescopic rod is released, the telescopic part of the hydraulic buffer telescopic rod can move back and forth within a certain range along the inner wall of the hydraulic buffer telescopic rod under the action of the impact force. By using the viscous resistance of the hydraulic oil to buffer and absorb energy, the impact force from the vehicle is greatly reduced, thereby achieving the effect of comprehensive buffer protection for the child.

[0018] This invention also utilizes a rotating locking ring to loosen the locking ring. When the locking ring is loosened, the adjusting screw is rotated via a knob. The threads on the outer curved surfaces of the adjusting screw at both ends face opposite directions. When the adjusting screw rotates, the force generated by the threaded connection causes the slider to move synchronously inward or outward along the inner wall of the limiting straight groove. As the slider moves synchronously inward or outward, the extension arm drives the buffer airbag to move synchronously outward or inward. This provides comprehensive cushioning protection for the child while allowing for simultaneous outward or inward adjustment of the cushioning protection range on both sides of the child's head and neck, thus improving the applicability of the buffer airbag.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 This utility model provides a child safety seat technical solution with a buffer structure: including a child safety seat body 1 and a mounting base 2 for installation inside a car;

[0026] The child safety seat body 1 has a buffer pad 3 fixedly installed inside the front end. The buffer pad 3 is composed of an inner layer, a middle layer, and an outer layer of buffer materials. The inner layer is made of high-elasticity memory foam, which can quickly respond to impact force, absorb and disperse energy. The middle layer is a honeycomb rubber pad, whose unique honeycomb structure can effectively buffer and guide the impact force to diffuse in all directions, avoiding stress concentration. The outer layer is covered with soft and wear-resistant environmentally friendly fabric, which can protect the internal buffer materials and provide a comfortable touch for children. The child safety seat body 1 has an installation strip 4 fixedly installed on the upper rear side. The front end of the installation strip 4 has a limiting straight slide groove 5, and the front end of the limiting straight slide groove 5 passes forward through the child safety seat body. At the upper end of body 1, the middle of the limiting straight slide groove 5 is rotatably connected to the adjusting screw 6 via a rotating shaft. The two ends of the adjusting screw 6 have opposite external curved thread orientations. A knob for rotating the adjusting screw 6 is fixedly installed on the side end of the adjusting screw 6. A locking ring 7 for locking and tightening the adjusting screw 6 is connected to the external curved thread on the side end of the adjusting screw 6. A slider 8 is connected to the external curved thread on both ends of the adjusting screw 6. The slider 8 is movably connected to the inner wall of the limiting straight slide groove 5, so that the slider 8 can be linearly moved and limited by the limiting straight slide groove 5. An extension arm 9 is fixedly installed at the front end of the slider 8. A buffer airbag 10 for cushioning and protecting the sides of the child's head and neck is fixedly installed on the inner side of the extension arm 9.

[0027] A hydraulic control cylinder 11 for controlling the delivery of hydraulic oil is fixedly installed at the bottom of the mounting base 2. Four hydraulic buffer telescopic rods 12 are fixedly installed on the front and rear sides of the upper end of the mounting base 2, arranged in pairs. The two sets of hydraulic buffer telescopic rods 12 are symmetrically distributed on the front and rear sides of the upper end of the mounting base 2. A support frame 13 is fixedly installed on the outer telescopic portion of the hydraulic buffer telescopic rod 12, and the upper end of the support frame 13 is fixedly installed on the front and rear sides of the lower end of the child safety seat body 1. A pressure sensor 14 for controlling the unlocking hydraulic control cylinder 11 is fixedly installed in the middle of the lower end of the child safety seat body 1. Hydraulic connection ports 15 are fixedly connected to the inner sides of the front and rear ends of the hydraulic buffer telescopic rod 12, and these ports are connected to the hydraulic control cylinder 11 via pipes, allowing the hydraulic control cylinder 11 to control the locking and releasing of the hydraulic oil inside the hydraulic buffer telescopic rod 12.

[0028] Working principle: In use, this utility model fixes the mounting base 2 inside the car. When the mounting base 2 is installed inside the car, hydraulic oil is added to the hydraulic buffer telescopic rod 12 by opening the hydraulic control cylinder 11. When the hydraulic buffer telescopic rod 12 is filled with hydraulic oil, it will maintain a full oil locked state. When the hydraulic buffer telescopic rod 12 is in a full oil locked state, the telescopic part of the hydraulic buffer telescopic rod 12, together with the support frame 13, provides overall rigid support for the child safety seat body 1, so that the child safety seat body 1 maintains a fixed posture. When the child safety seat body 1 is in a fixed position, the cushioning pad 3 will cushion and protect the child's body. The cushioning pad 3 is composed of inner, middle and outer cushioning materials. The inner layer is made of high-elasticity memory foam, which can quickly respond to impact force, absorb and disperse energy. The middle layer is a honeycomb rubber pad. Its unique honeycomb structure can effectively cushion and guide the impact force to diffuse in all directions to avoid stress concentration. The outer layer is wrapped with soft and wear-resistant environmentally friendly fabric, which can protect the internal cushioning material and provide a comfortable touch for the child. The cushioning airbag 10 will cushion and protect the sides of the child's head and neck.

[0029] When a collision occurs, the pressure sensor 14, which is fixedly installed in the middle of the lower end of the child safety seat body 1, will quickly sense the impact force and trigger the unlocking hydraulic control cylinder 11. When the hydraulic control cylinder 11 triggers the unlocking, it will release the hydraulic oil inside the hydraulic buffer telescopic rod 12 through the hydraulic connection port 15. When the hydraulic oil inside the hydraulic buffer telescopic rod 12 is released, the telescopic part of the hydraulic buffer telescopic rod 12 can move back and forth within a certain range along the inner wall of the hydraulic buffer telescopic rod 12 under the action of the impact force. It uses the viscous resistance of the hydraulic oil to buffer and absorb energy, greatly reducing the impact force from the vehicle, thereby achieving the effect of comprehensive buffer protection for the child.

[0030] Simultaneously, by rotating the locking ring 7 to loosen it, the adjusting screw 6 is turned by the knob. The threads on the outer curved surfaces at both ends of the adjusting screw 6 face opposite directions. When the adjusting screw 6 is turned, the force generated by the threaded connection will drive the slider 8 to move in a straight line inward or outward along the inner wall of the limiting straight slide groove 5. When the slider 8 moves in a straight line inward or outward, it will drive the buffer airbag 10 to move in a straight line outward or inward in a straight line through the extension arm 9. This achieves comprehensive buffer protection for the child while facilitating simultaneous outward or inward adjustment of the buffer protection range on both sides of the child's head and neck, thereby improving the applicability of the buffer airbag 10.
