Technical Field
[0001] This utility model relates to the field of automotive parts and safety technology, specifically to a child safety seat. Background Technology
[0002] In the field of automotive safety, child car seats play a crucial role in ensuring the safety of children while traveling in vehicles. To accommodate the seating needs of children of different ages, existing child car seats generally feature fore-and-aft adjustment. However, in practical applications, current technology has significant drawbacks in terms of backrest adjustment.
[0003] Taking the child safety seat invention patent application with application number 202510261895.2 as an example, when adjusting the tilt angle, the second connecting piece fixed on the rotating disc will have a relative movement with the seat back. To facilitate positioning with the base, a second connecting hook is specially provided on the top of the second connecting piece. However, to allow the second connecting hook room to move up and down, only an adjustment hole can be provided on the seat back for this movement. This adjustment hole remains exposed after adjustment, severely affecting the product's aesthetics. For example, in some child safety seat models on the market, the exposed adjustment hole on the seat back makes the overall appearance appear rough, ruining the original refined feel of the seat. At the same time, the adjustment hole easily accumulates dust and debris, making cleaning difficult. Long-term accumulation of dust may also hinder the normal operation of internal seat components, shortening the seat's lifespan.
[0004] While some child safety seats feature decorative panels over the adjustment holes, traditional panels are often manually operated. After adjusting the seat forward and backward, users must manually cover the adjustment holes with the panel, a cumbersome process. Parents have reported that installing and operating the decorative panels on some child safety seats is quite complex, and busy parents are prone to forgetting to do so, leaving the adjustment holes exposed and significantly reducing the user experience.
[0005] In summary, the key issue that urgently needs to be addressed is how to develop a child safety seat with a linkage structure that connects the seat adjustment action with the movement of the trim panel, automatically covering the backrest adjustment holes, simplifying the trim panel operation process, and improving user experience and product quality. Utility Model Content
[0006] The technical problem to be solved by this utility model is to provide a child safety seat that can effectively solve the aesthetic and cleaning problems caused by the exposed adjustment holes on the back of the seat, and can simplify the operation process of the decorative panel by setting a linkage structure, so as to realize the automatic covering of the adjustment holes on the back of the seat.
[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a child safety seat, including a chassis and a seat body that moves relative to the chassis during adjustment. The chassis is provided with a connector, which moves relative to the seat body during adjustment. The back of the seat body is provided with an adjustment hole to avoid the protruding part of the connector. A linkage automatic cover structure is provided between the seat body and the connector. The linkage automatic cover structure includes a flexible decorative panel and a fixing component.
[0008] The upper end of the flexible decorative panel is fixed to the back of the seat body, and the lower end is fixed to the connector.
[0009] The fixing component is configured to automatically cover the adjustment hole by guiding or elastically deforming or displacing the flexible decorative panel when the connector moves relative to the seat body.
[0010] To further optimize the form of the automatic covering structure, making it more flexible, convenient, and adaptable in realizing the automatic covering function, preferably, the flexible decorative panel is a foldable telescopic curtain, and the fixing component includes a first mounting part and a second mounting part. The upper end of the telescopic curtain is fixed to the back of the seat body through the first mounting part, and the lower end is fixed to the connector through the second mounting part. The telescopic curtain automatically covers the adjustment hole by folding or unfolding when moving relative to the seat body.
[0011] To make the connection between the retractable curtain and the seat body and connectors more stable and reliable, and to facilitate installation and disassembly and improve the maintainability of the product, preferably, the first mounting part includes fasteners, and the top of the retractable curtain is fixedly connected to the back of the seat body by the fasteners.
[0012] The second mounting part includes a buckle located at the bottom of the telescopic curtain. The connector has a locking hole adapted to the buckle. The buckle and the locking hole are fastened together to achieve a detachable connection at the bottom of the telescopic curtain.
[0013] To ensure a secure connection between the buckle and the locking hole, prevent loosening during use, and guarantee the stable operation of the retractable curtain, preferably, the locking hole includes a large hole and a small hole that are interconnected. The size of the large hole is larger than the head of the buckle, and the size of the small hole is adapted to the neck of the buckle. After being inserted into the large hole, the buckle moves laterally to the small hole and is locked in the small hole by the elastic deformation of the buckle neck.
[0014] In order to provide another reliable automatic covering structure and enrich the product selection so that the product can meet the user's needs in different usage scenarios, preferably, the flexible decorative panel is a roller blind, and the fixing component includes a roller mounting part and a free end fixing part;
[0015] The roller mounting part includes a roller bracket located on the back of the seat body for fixing the roller of the blind.
[0016] The free end fixing part includes a clamping structure or magnetic adsorption component disposed on the connector for fixing the roller of the blind.
[0017] The rolling or unfolding of the blind is achieved by the relative movement of the seat body and the connecting piece.
[0018] In order to enable the roller blind to operate more smoothly during the automatic covering process, and to achieve winding and unfolding without additional power, thereby improving the convenience of use, preferably, the roller blind's roller shaft has a built-in torsion spring, one end of which is fixed to the roller shaft bracket and the other end is fixed to the roller shaft.
[0019] When the connector and the seat body are in a state of relative movement, the free end of the roller blind is stretched or released, and the torsion spring drives the roller to automatically wind or unfold the roller blind through elastic potential energy.
[0020] In order to add another effective automatic covering structure solution, further enhance the diversity and practicality of the product, and meet the preferences of different users for product structure, preferably, the flexible decorative panel is a curtain, and the fixing component includes a tension spring and a transition shaft;
[0021] One end of the curtain is fixed to the back of the seat body by a tension spring, and the other end is fixed to the connector. The transition shaft is located on the back of the seat body and is slidably connected to the middle of the curtain.
[0022] When the connector is in the downward position, the curtain is pulled to cover the adjustment hole; when the connector is in the upward position, the tension spring causes the curtain to retract.
[0023] In order to reduce the frictional resistance of the curtain during movement, improve the service life of the curtain, and enable the curtain to better adapt to the coverage needs of different adjustment levels, preferably, the transition shaft can rotate around its own axis to disperse the tensile stress of the curtain and reduce frictional resistance.
[0024] The end of the tension spring is fixed to the back of the seat body by an adjustable bolt. The adjustable bolt is used to adjust the preload of the tension spring to adapt to the coverage requirements of different adjustment levels.
[0025] To ensure the stability and accuracy of the flexible decorative panel's movement during the automatic covering process, and to ensure that it can always accurately cover the adjustment hole, preferably, the guiding function of the fixing component is achieved through a guide groove or slide rail, which is set on the back of the seat body to constrain the movement path of the flexible decorative panel.
[0026] To better adapt the automatic covering structure to the seat's adjustment function and ensure effective coverage of the adjustment holes at different adjustment levels, thereby improving the product's applicability, preferably, the relative movement between the connector and the seat body is a pitch angle adjustment, and the covering range of the flexible decorative panel corresponds to the adjustment holes exposed after the pitch angle adjustment, so as to dynamically cover the adjustment holes exposed after adjustment.
[0027] Compared with existing technologies, the advantages of this utility model are as follows: By setting a linkage-type automatic covering structure between the seat body and the connecting member, this structure includes a flexible decorative panel with its upper end fixed to the back of the seat body and its lower end fixed to the connecting member, and a fixing component that can guide or elastically deform or displace the flexible decorative panel to automatically cover the adjustment holes when the connecting member and the seat body move relative to each other. Since the upper end of the flexible decorative panel is fixed to the back of the seat body and the lower end is connected to the connecting member, the fixing component will guide or elastically deform or displace the flexible decorative panel when the two move relative to each other, perfectly achieving a seamless connection between the seat adjustment action and the movement of the decorative panel. The linkage realizes the automatic covering of the back adjustment holes, which not only solves the problem of the exposed back adjustment holes affecting the aesthetics in existing technologies, but also avoids the accumulation of dust and debris in the adjustment holes, reducing the difficulty of cleaning; at the same time, it simplifies the operation process of the decorative panel, improves the user experience and product quality.

[0036] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0037] Figures 1 to 8 The diagram shows three embodiments of this utility model. The child safety seats in embodiments 1 to 3 all include components such as chassis 1, seat body 2, connector 3, adjustment hole 4, flexible decorative panel 5, and fixing component 6. The three different embodiments are described in detail below with reference to the accompanying drawings.
[0038] Example 1
[0039] This embodiment 1 corresponds to Figures 1 to 4 This product is suitable for child safety seat usage scenarios that prioritize ease of operation and aesthetics. The structure and connection relationships of its components are as follows:
[0040] refer to Figure 1 The chassis 1 serves as the basic support structure, providing a stable mounting platform for the seat body 2. The seat body 2 can be adjusted relative to the chassis 1 to meet different usage needs. The connector 3 is mounted on the chassis 1 and moves relative to the seat body 2 during adjustment. An adjustment hole 4 is provided on the back of the seat body 2 to avoid the protruding part of the connector 3, ensuring smooth adjustment.
[0041] refer to Figures 2 to 4 As shown, in Embodiment 1, the flexible decorative panel 5 adopts a foldable telescopic curtain, and the fixing component 6 includes a first mounting part 6a and a second mounting part 6b. The fastener 6a1 of the first mounting part 6a firmly fixes the top of the telescopic curtain to the back of the seat body 2, ensuring a stable connection. The buckle 6b1 of the second mounting part 6b is located at the bottom of the telescopic curtain, and the connector 3 is provided with a matching buckle hole 31, which is composed of a large hole 31a and a small hole 312 communicating with each other. During installation, the buckle 6b1 is inserted from the large hole 31a and then moves laterally to the small hole 312. The elastic deformation of the neck of the buckle 6b1 locks it in the small hole 312, realizing a detachable connection between the bottom of the telescopic curtain and the connector 3.
[0042] To ensure the stability of the telescopic curtain during movement, refer to Figure 3 and Figure 4 As shown, a guide groove 7 is also provided on the back of the seat body 2. The edge of the telescopic curtain cooperates with the guide groove 7, so that it can only move along the preset path.
[0043] The assembly process of each component in Example 1 is as follows:
[0044] First, install the connector 3 onto the chassis 1, ensuring a secure and accurate installation. Next, install the guide groove 7 onto the back of the seat body 2, ensuring the guide groove 7 is installed precisely. Then, use fasteners 6a1 to secure the top of the retractable curtain to the back of the seat body 2. After that, align the buckle 6b1 at the bottom of the retractable curtain with the locking hole 31 on the connector 3, and complete the installation according to the steps. Finally, install the seat body 2 onto the chassis 1, ensuring a tight connection and normal relative movement.
[0045] The working principle of the linkage automatic covering structure in Example 1 is as follows:
[0046] When the seat body 2 needs adjustment, such as for tilt adjustment, the seat body 2 moves relative to the chassis 1, causing the connecting piece 3 to move relative to it. If the seat body 2 is adjusted upwards, the connecting piece 3 moves downwards, and the retractable curtain gradually unfolds under the pull of the connecting piece 3. Due to the constraint of the guide groove 7, the retractable curtain unfolds smoothly along the predetermined path, automatically covering the adjustment hole 4. When the seat body 2 is adjusted downwards, the connecting piece 3 moves upwards, and the retractable curtain gradually folds, but always maintains coverage of the adjustment hole 4, effectively preventing the adjustment hole 4 from being exposed, improving the aesthetics and ease of cleaning of the seat.
[0047] Example 2
[0048] Example 2 corresponds to Figure 5 and Figure 6 This design is suitable for scenarios where a clean appearance of the seat and the stability of the automatic blinding structure are critical. In Embodiment 2, the flexible decorative panel 5 is a roller blind. The fixing component 6 includes a roller mounting part 6c and a free end fixing part 6d. The roller mounting part 6c includes a roller bracket 6c1 located on the back of the seat body 2. The roller bracket 6c1 is used to fix the roller blind's roller 51. The roller blind's roller 51 has a built-in torsion spring. One end of the torsion spring is fixed to the roller bracket 6c1, and the other end is fixed to the roller 51. Since the torsion spring here is a conventional structure for roller blinds, it is not shown in detail in the attached drawings. The free end fixing part 6d adopts a clamping structure 6d1 located on the connector 3, mainly used to fix the free end 52 of the roller blind. To make the roller blind more stable during movement, the back of the seat body 2 can also be equipped with guide grooves or slide rails to guide and cooperate with the edge of the roller blind.
[0049] During assembly, first install the roller bracket 6c1 on the back of the seat body 2, then install the roller 51 with the built-in torsion spring 53 onto the roller bracket 6c1. Next, fix the free end 52 of the roller blind to the connector 3 using the clamping structure 6d1. Finally, install the seat body 2 onto the chassis 1, ensuring that the guide groove or slide rail fits well with the roller blind.
[0050] The working principle of the linkage automatic covering structure in Example 2 is as follows:
[0051] When tilt adjustment is required, the seat body 2 moves, causing relative movement with the connecting piece 3. If the seat body 2 is adjusted upwards, the connecting piece 3 moves downwards, stretching the free end 52 of the roller blind, causing the roller shaft 51 to rotate, and the torsion spring to store elastic potential energy. When the seat body 2 is adjusted downwards, the connecting piece 3 moves upwards, releasing the elastic potential energy and driving the roller shaft 51 to automatically wind the roller blind, ensuring it always covers the adjustment hole 4. Throughout the process, the guide groove or slide rail ensures stable movement of the roller blind, while the power provided by the torsion spring makes the winding and unfolding of the roller blind smoother, effectively improving the automatic covering effect and reliability.
[0052] Example 3
[0053] Example 3 Corresponding Figure 7 and Figure 8 It is suitable for scenarios where there are special requirements for the flexibility and adjustability of the automatic seat cover structure, such as situations where the seat angle needs to be adjusted frequently.
[0054] In Example 3, the flexible decorative panel 5 is a curtain, and the fixing assembly 6 includes a tension spring 6e and a transition shaft 6f. One end of the curtain is fixed to the back of the seat body 2 by the tension spring 6e, and the end of the tension spring 6e can also be fixed by an adjustable bolt 6e1, which allows for easy adjustment of the preload of the tension spring 6e. The transition shaft 6f is located on the back of the seat body 2 and is slidably connected to the middle of the curtain. The transition shaft 6f can rotate around its own axis to distribute the tensile stress of the curtain and reduce frictional resistance. The other end of the curtain is fixed to the connector 3. Similarly, the back of the seat body 2 is also provided with a guide groove or slide rail to constrain the movement path of the curtain.
[0055] During assembly, first install the transition shaft 6f on the back of the seat body 2, ensuring it can rotate freely. Next, use the adjustable bolt 6e1 to fix one end of the tension spring 6e to the back of the seat body 2, then connect one end of the curtain to the tension spring 6e, with the middle of the curtain slidably connected to the transition shaft 6f. Then, fix the other end of the curtain to the connector 3. Finally, install the seat body 2 and the chassis 1, and check the fit between the guide groove or slide rail and the curtain.
[0056] The working principle of the linkage automatic covering structure in Example 3 is as follows:
[0057] When tilt adjustment is required, the seat body 2 moves, causing relative movement with the connecting piece 3. When the connecting piece 3 moves downward, the curtain is pulled, smoothly covering the adjustment hole 4 with the assistance of the transition shaft 6f. When the connecting piece 3 moves upward, the tension spring 6e drives the curtain to retract. By adjusting the adjustable bolt 6e1, the preload of the tension spring 6e can be changed to adapt to the coverage requirements of different adjustment levels. For example, when adjusting at a larger angle, the preload of the tension spring 6e is increased to ensure that the curtain completely covers the adjustment hole 4; when adjusting at a smaller angle, the preload is appropriately reduced to make the curtain move more flexibly. The guide groove or slide rail ensures the stability of the curtain during movement, and the rotation of the transition shaft 6f effectively reduces the wear of the curtain, improving the service life and adaptability of the entire structure.
