Description

Technical Field

[0001] This utility model relates to the field of child car seat technology, and specifically to a child car seat side protection structure. Background Technology

[0002] Child safety seats are car safety equipment specifically designed for children of different ages (or weights). Their core function is to effectively disperse impact force and restrict the child's body displacement in sudden situations such as sudden braking and collisions, through an ergonomic structure that conforms to the characteristics of children's skeletal development. This prevents the child from being thrown out or directly colliding with hard objects inside the vehicle. At the same time, it avoids the risk of strangulation injuries to children caused by adult seat belts that do not fit properly. When using a child safety seat, the corresponding group should be selected according to the child's age and weight, and the seat should be installed and secured correctly in strict accordance with the instruction manual.

[0003] Currently, most child car seat side protection designs on the market fix energy-absorbing materials directly to the seat body using clips, screws, or adhesives, making it impossible to adjust their position. This causes the fit between the energy-absorbing module and the child's body to gradually decrease over time, weakening the protective effect. Furthermore, the energy-absorbing modules, support frames, and connecting components of existing side protection structures are quite complex, resulting in complicated assembly processes, increased production complexity, higher production costs, and inconvenient operation.

A reset block, a rotating shaft, and a reset elastic element are installed inside the side protection base. The side protection component is installed outside the side protection base.

[0007] The rotating shaft passes through the reset block and is rotatably connected to the side protection base, and the side protection component is rotatably connected to the side protection base through the rotating shaft.

[0008] As a further description of the above technical solution, an installation groove is provided on the upper outer side of the chair body, and the installation groove is used to install the side protection base.

[0009] As a further description of the above technical solution, a sliding groove is provided in the middle of one side of the side protection base, and the sliding groove is used to install the reset block.

[0014] As a further description of the above technical solution, the reset block is inserted into the rotating shaft through a shaft hole opened at its end.

[0015] As a further description of the above technical solution, the reset elastic element is disposed between the side protection base and the reset block.

[0016] As a further description of the above technical solution, a reset torque element is installed at the end of the rotating shaft.

[0017] The beneficial effects of this utility model are as follows:

[0018] In this invention, by pulling one end of the side protective component in the forward direction, it rotates around the rotation axis, simultaneously driving the reset block to slide upward along the sliding groove. When the side protective component rotates to a set angle, the end connected to the rotation axis slides into the locking groove, at which point the side protective component enters the unlocked locking state. By pulling one end of the side protective component in the reverse direction, it disengages from the locking groove, allowing the side protective component to rotate in the opposite direction around the rotation axis, at which point the rotating side protective component enters the closed retracted state.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0029] like Figures 1-6 As shown, in one embodiment, a child seat side protection structure includes a seat body 010, on which a side protection component for resisting side impact is specifically installed.

[0030] The side protection component includes a side protection base 020, inside which a reset block 040 for locking and unlocking functions, a rotating shaft 050 for driving the component to rotate, and a reset elastic element 060 for providing elastic reset force are installed. Outside the side protection base 020, a side protection element 030 that directly contacts the side impact is assembled.

[0031] Specifically, the upper left and right outer sides of the chair body 010 are provided with mounting grooves 011 that precisely match the shape of the side protection base 020. The mounting groove 011 is designed as a recessed groove structure to ensure that the side protection base 020 can remain flat with the surface of the chair body 010 after installation, without producing any protrusions, thus avoiding scratching the child; the side protection component 030 is made of energy-absorbing materials such as EPP and EPS, which can effectively absorb collision energy and reduce the impact on the child's body.

[0032] Correspondingly, the side protection base 020 can be detachably installed on the mounting slot 011 of the chair body 010 via connectors (such as screws, clips, etc.): if screw connection is used, the screw holes must be precisely aligned to ensure the connection is stable and prevent the base from loosening due to vehicle bumps; if clip connection is used, the clip must have sufficient elasticity and locking force to facilitate disassembly, maintenance and component replacement in the future, and ensure installation stability during daily use.

[0033] Furthermore, a vertically elongated sliding groove 021 is provided in the middle of one side of the side protection base 020. The groove size of the sliding groove 021 is strictly matched with the shape of the reset block 040. The inner wall is polished smooth to reduce friction. This is used to stably install the reset block 040. In the process of the reset block 040 sliding up and down in the sliding groove 021, the locking and unlocking of the side protection component 030 is accurately completed through the linkage with the rotating shaft 050 and the side protection component 030.

[0034] Correspondingly, a locking groove 022 is provided on the bottom side of the side protection base 020, which is adapted to the connection end of the rotating shaft 050 of the side protection component 030. This groove is used to tightly lock the side protection component 030, so that the side protection component 030 and the rotating shaft 050 can slide into the locking groove 022 after rotation, and achieve a stable lock by the protrusion engagement, and quickly release the lock when disengaging from the locking groove 022.

[0035] In addition, a latching groove 023 is provided on the other side of the side protection base 020. The groove is shaped to fit the size of a finger, making it easy for the user to insert their finger and apply force. The function of the latching groove 023 is to provide a point of force for turning the side protection component 030. When it is necessary to open the side protection component 030, the user does not need to find other points of leverage. They can simply insert their finger into the latching groove 023 to easily apply force and turn the side protection component 030. This effectively avoids the problem of difficulty in applying force due to the smooth surface of the side protection component 030, and significantly improves the ease of operation.

[0036] Please continue reading. Figures 1-6 In this embodiment, the reset block 040 is slidably connected to the side protection member 030 through the sliding groove 021 to ensure that the reset block 040 will not deviate or get stuck when sliding.

[0037] Furthermore, the reset block 040 has a shaft hole at its end, so that the reset block 040 can be inserted into the rotating shaft 050 through the shaft hole;

[0038] Specifically, the rotating shaft 050 passes through the reset block 040 and is rotatably connected to the side protection base 020. The rotating shaft 050 can be made of high-strength plastic or lightweight metal material, taking into account both load-bearing performance and torsional strength. Its end passes through the shaft hole of the reset block 040 and is rotatably connected to the side protection base 020. The side protection component 030 is connected to the rotating shaft 050 through its own preset connecting hole. The connecting hole and the rotating shaft 050 adopt an interference fit to ensure that the rotating shaft 050 can synchronously drive the side protection component 030 to rotate when it rotates, without relative slippage, and to ensure the consistency of component linkage.

[0039] Furthermore, the reset elastic element 060 is disposed between the side protection base 020 and the reset block 040; specifically, the reset elastic element 060 can be a compression spring, etc. When the reset block 040 slides, the compression spring can provide elastic force through its own extension and contraction. When the side protection element 030 needs to be reset, the compression spring can push the reset block 040 back to the initial position to assist in completing the state switching.

[0040] Correspondingly, a reset torque component 070 is installed at the end of the rotating shaft 050; specifically, the reset torque component 070 can be a torsion spring, etc. The torsion spring will simultaneously store or release force during the opening and closing of the side protection component 030, assisting the side protection component 030 to rotate smoothly to the target state.

[0041] Working principle:

[0042] (1) When one end of the side protection member 030 is pulled in the forward direction, force can be applied through the latching groove 023 to pull the free end of the side protection member 030 away from the chair body 010. The side protection member 030 rotates around the rotating shaft 050 in the direction away from the chair body. During this process, the reset block 040 is simultaneously driven to slide in the forward direction along the sliding groove 021. At the same time, the compression spring is compressed and the torsion spring gradually stores force. When the side protection member 030 rotates to the set angle (the angle range is 30°-60°, which can be adjusted according to the child's body size and protection needs), the connection end of the side protection member 030 and the rotating shaft 050 slides precisely into the locking groove 022, and the side protection member 030 enters the unlocked locking state.

[0043] (2) When one end of the side protection piece 030 is pulled in the opposite direction, the elastic force of the compression spring can be overcome by pulling the connection end of the side protection piece 030 and the rotating shaft 050, so that the connection end is disengaged from the locking groove 022; at the moment of disengagement, the torsion spring releases its stored force, and the side protection piece 030 rotates in the opposite direction around the rotating shaft 050 in the direction close to the chair body. At the same time, the side protection piece 030 drives the reset block 040 to slide in the opposite direction along the sliding groove 021 through the rotating shaft 050, and the compression spring gradually resets; as the side protection piece 030 continues to rotate until it is in contact with the side of the chair body 010, the reset block 040 returns to the initial position, and the side protection piece 030 enters the closed and retracted state.

[0044] With the above technical solution, the number of structural parts in this application is small, which not only reduces production and procurement costs, but also reduces assembly steps; the overall assembly process is simple, and each component can be assembled by simple connection methods such as shaft holes, screws, and snap fasteners, which effectively shortens the production cycle and reduces the risk of assembly errors; the opening and closing operation does not require tools and can be completed by manually turning or pulling, which effectively improves the ease of operation.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
