Description

Technical Field

[0001] This utility model relates to the field of child safety seat technology, and in particular to a guide rail system for a sliding mechanism and a child safety seat. Background Technology

[0002] Child safety seats are essential tools when traveling with children in a car, and they are usually fixed in the rear seat of the car.

[0003] To facilitate users placing children into and removing them from their car seats while standing outside the vehicle, a sliding mechanism is installed in the car seats. This mechanism mainly consists of a sliding seat mounted on the rotating seat, with the seat itself mounted on the sliding seat. When it is necessary to remove or place a child, first rotate the rotating seat so that the seat faces the door, then slide the sliding seat relative to the rotating seat, allowing the seat to slide sideways towards the door for easy removal or placement of the child.

[0004] In the sliding mechanism of a child safety seat, an outer slide rail is provided on the rotating seat, and an inner slide rail is provided on the sliding seat. The inner and outer slide rails are nested together and can slide relative to the outer slide rail. In existing child safety seat sliding mechanisms, both the upper and lower ends of the outer and inner slide rails are bent to form limiting plates, and ball bearings (similar to drawer slide structure) are installed between the limiting plates at the upper and lower ends of the inner and outer slide rails to ensure reliable sliding and prevent the inner and outer slide rails from easily disengaging. However, both the inner and outer slide rails require multiple bending to manufacture, which is not only troublesome and inefficient but also costly. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose a guide rail system for a sliding mechanism that can reduce the number of bends, is easy to manufacture and has low cost, and a child safety seat.

[0006] The technical solution adopted by this utility model to solve its technical problem is to propose a guide rail system for a sliding mechanism, which is installed in a child safety seat. The sliding mechanism includes a rotating base and a sliding base disposed on the rotating base. The guide rail system includes:

[0007] The first outer slide rail and the second outer slide rail are arranged at intervals on the rotating seat, and both the first outer slide rail and the second outer slide rail include a first side plate;

[0008] The first inner slide rail and the second inner slide rail are respectively disposed on both sides of the sliding seat and are located between the two first side plates. The first inner slide rail and the second inner slide rail each include a second side plate. One second side plate is slidably disposed on one first side plate, and the other second side plate is slidably disposed on the other first side plate.

[0009] One of the first side plate and the second side plate is provided with a guide slide structure, and the other side plate is provided with a slide groove, and the slide groove is opened along the sliding direction of the sliding seat, and the guide slide structure passes through the slide groove;

[0010] When the sliding seat slides relative to the rotating seat, the two second side plates slide relative to the two first side plates respectively, and the relative position of the guide structure in the slide groove changes.

[0011] Furthermore, the guide structure is configured as a rivet, and the second side plate and the first side plate are connected by the rivet, and the rivet restricts the second side plate from detaching from the first side plate.

[0012] Furthermore, the slide groove includes an upper slide groove and a lower slide groove arranged in parallel, and each of the upper slide groove and the lower slide groove is provided with a guide structure.

[0013] Furthermore, the guide structure can abut against both ends of the slide groove to control the travel of the sliding seat relative to the rotating seat.

[0014] Furthermore, both the first and second outer slide rails include a fixedly connected metal frame and a plastic cover, with the plastic cover covering the metal frame;

[0015] The first and second inner slide rails are made of metal and are slidably mounted on the plastic cover, which restricts the first and second inner slide rails from contacting the metal frame.

[0016] Furthermore, the plastic cover is provided with a positioning protrusion and a buckle, and the metal frame is provided with a positioning hole. The positioning protrusion extends into the positioning hole, and the buckle is engaged with the metal frame, so that the plastic cover is fixed to the metal frame.

[0017] Furthermore, the first outer slide rail and the second outer slide rail are symmetrically arranged and each includes a base plate, and the first side plate extends upward from one side of the base plate;

[0018] The first and second outer slide rails are mounted on the rotating seat and form an open-top mounting space on the rotating seat;

[0019] The first inner slide rail and the second inner slide rail are mounted on the sliding seat, and the sliding seat can be mounted in the installation space from top to bottom.

[0020] Furthermore, the rivet has a rivet head at one end near the groove, and the size of the rivet head is larger than the width of the groove.

[0021] Furthermore, the first inner slide rail and the second inner slide rail are symmetrically arranged and each includes several folded ears. The folded ears are formed by bending from the second side plate and are used to connect with the sliding seat or the seat of the child safety seat.

[0022] This utility model also proposes a child safety seat, wherein the child safety seat is equipped with the guide rail system of the aforementioned sliding mechanism.

[0023] Compared with the prior art, the present invention has at least the following beneficial effects:

[0024] In this utility model, the guide rail system of the slide rail mechanism includes a first outer slide rail and a second outer slide rail, both of which include a first side plate. The second inner slide rail and the second inner slide rail also include a second side plate. The two second side plates are slidably mounted on the two first side plates, and the first and second side plates cooperate with each other through a guide structure and a sliding groove. This eliminates the need to bend the upper and lower ends of the first and second side plates to form limiting folds, effectively reducing the number of bends in the first outer slide rail, the second outer slide rail, the first inner slide rail, and the second inner slide rail. This eliminates the need for multiple bending processes and thus reduces the cost of the child safety seat.

[0025] In this invention, the guide slide structure is configured with rivets, which connect the second side plate and the first side plate and prevent the second side plate from detaching from the first side plate, ensuring a reliable connection between the inner and outer slide rails. Furthermore, the slide groove includes an upper slide groove and a lower slide groove, and a guide slide structure is provided in both the upper and lower slide grooves to ensure reliable guiding.

[0026] In this utility model, both the first outer slide rail and the second outer slide rail include a metal frame and a plastic cover that are fixedly connected. The plastic cover covers the metal frame, and the inner slide rail made of metal is slidably set on the plastic cover. The plastic cover separates the metal frame from the inner slide rail, which can effectively reduce noise and wear, prevent friction between metals, and the two metal frames can respectively ensure the structural strength of the two outer slide rails.

[0027] In this utility model, both the first outer slide rail and the second outer slide rail include a base plate and a first side plate extending upward from one side of the base plate. There is no bending plate on the first side plate. Therefore, the first outer slide rail and the second outer slide rail together form an open-top installation space on the rotating seat, which makes it convenient for the sliding seat with the inner slide rail to be installed in the installation space from top to bottom, making installation easy.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0047] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0048] like Figures 1-6 As shown, a guide rail system for a sliding mechanism in this embodiment is installed on a child safety seat. The sliding mechanism includes a rotating seat 50 and a sliding seat 60 disposed on the rotating seat 50. The rotating seat 50 is rotatably mounted on the base of the child safety seat and is disc-shaped, with its center being the rotation center of the rotating seat 50. By rotating the rotating seat 50, the orientation of the child in the child safety seat can be adjusted. When the child is rotated to face the side (e.g., the side facing the car door), the sliding seat is released from its restriction and can slide relative to the rotating seat 50, facilitating the placement of the child in the child safety seat and the removal of the child from the child safety seat.

[0049] The guide rail system of this embodiment mainly includes: a first outer slide rail 1, a second outer slide rail 2, a first inner slide rail 3, and a second inner slide rail 4. Since the first outer slide rail 1 and the second outer slide rail 2 are located outside the first inner slide rail 3 and the second inner slide rail 4 from a relative positional perspective, they are referred to as outer slide rails; while the first inner slide rail 3 and the second inner slide rail 4 are located inside the first outer slide rail 1 and the second outer slide rail 2, and are referred to as inner slide rails. The first outer slide rail 1 and the second outer slide rail 2 are spaced apart on the rotating seat 50, and both the first outer slide rail 1 and the second outer slide rail 2 include a first side plate 121, with the first side plate 121 and the second side plate 341 located on opposite sides of the sliding seat 60.

[0050] The first inner slide rail 3 and the second inner slide rail 4 are respectively disposed on both sides of the sliding seat 60 and are located between the two first side plates 121. The first inner slide rail 3 and the second inner slide rail 4 both include a second side plate 341. One second side plate 341 is slidably disposed on one first side plate 121, and the other second side plate 341 is slidably disposed on the other first side plate 121.

[0051] Furthermore, one of the first side plate 121 and the second side plate 341 is provided with a guide sliding structure 340, and the other is provided with a sliding groove 120. The sliding groove 120 is opened along the sliding direction of the sliding seat 60, and the guide sliding structure 340 passes through the sliding groove 120. It should be explained that when the first side plate 121 is provided with the guide sliding structure 340, the second side plate 341 is provided with the sliding groove 120, and vice versa. Both methods can achieve sliding engagement between the first side plate 121 and the second side plate 341. Ideally, in this embodiment, only the scheme of providing a sliding groove 120 on the first side plate 121 and a guide sliding structure 340 on the second side plate 341 will be described in detail.

[0052] In actual use, when the sliding seat 60 slides relative to the rotating seat 50, the two second side plates 341 slide relative to the two first side plates 121 respectively, and the relative position of the guide structure 340 in the slide groove 120 changes. Since this embodiment only details the slide groove 120 on the first side plate 121 and the guide structure 340 on the second side plate 341, the slide groove 120 is stationary, while the guide structure 340 is movable. The slide groove 120 and the guide structure cooperate to guide the second side plate 341 when it slides relative to the first side plate 121.

[0053] In the guide rail system of this embodiment, the first outer slide rail 1 and the second outer slide rail 2 both include a first side plate 121, and the second inner slide rail 4 and the second inner slide rail 5 both include a second side plate 341. The two second side plates 341 are slidably disposed on the two first side plates 121, and the first side plates 121 and the second side plates 341 cooperate with each other through the guide sliding structure 340 and the slide groove 120. It is not necessary to bend the upper and lower ends of the first side plates 121 and the second side plates 341 to form limiting folding plates. This can effectively reduce the number of bends of the first outer slide rail 1, the second outer slide rail 2, the first inner slide rail 3 and the second inner slide rail 4, and eliminate the need for multiple bending processes, thereby reducing the cost of the child safety seat.

[0054] In existing child safety seat sliding mechanisms, the edges of the outer slide rail in the guide rail system are bent inward at both ends to form limiting plates, and the edges of the inner slide rail in the guide rail system are bent outward at both ends to form limiting plates. The outer and inner slide rails slide and cooperate through the limiting plates for guidance and limitation, forming a nested fit. Therefore, both the outer and inner slide rails require multiple bending processes, which is cumbersome. Moreover, bending the entire edge makes it difficult to guarantee the bending quality.

[0055] Specifically, in this embodiment, the guide structure 340 is configured as a rivet, and the second side plate 341 and the first side plate 121 are connected by the rivet, which prevents the second side plate 341 from detaching from the first side plate 121. The end of the rivet near the slide groove 120 has a rivet head, the size of which is larger than the width of the slide groove 120, ensuring that the rivet cannot detach from the slide groove 120, thereby ensuring structural stability. If it is necessary to remove the rivet from the slide groove 120, the rivet must be destroyed before riveting.

[0056] Because the rivet is larger at both ends and smaller in the middle, it can restrict the separation between the second side plate 341 and the first side plate 121. Furthermore, the guide structure 340 can abut against both ends of the slide groove 120, controlling the travel of the sliding seat 60 relative to the rotating seat 50. For example, the total length of the slide groove 120 can be made equal to the maximum travel of the sliding seat 60.

[0057] Furthermore, in this embodiment, the slide groove 120 includes an upper slide groove 120A and a lower slide groove 120B arranged in parallel, and a guide structure 340 is provided in the upper slide groove 120A and the lower slide groove 120B respectively. The outer slide rail and the inner slide rail on each side are guided by two rivets in conjunction with the upper slide groove 120A and the lower slide groove 120B, which can ensure that the sliding of the inner slide rail relative to the outer slide rail is reliable.

[0058] In practical use, the guide structure 340 of this embodiment is set as a rivet, which connects the second side plate 341 and the first side plate 121, and can prevent the second side plate 341 from detaching from the first side plate 121, ensuring reliable connection between the inner and outer slide rails. Furthermore, the slide groove 120 includes an upper slide groove 120A and a lower slide groove 120B, and a guide structure 340 is provided in both the upper slide groove 120A and the lower slide groove 120B to ensure reliable guiding.

[0059] More specifically, in this embodiment, both the first outer slide rail 1 and the second outer slide rail 2 include a fixedly connected metal frame 12A and a plastic cover 12B, with the plastic cover 12B covering the metal frame 12A. The first inner slide rail 3 and the second inner slide rail 4 are made of metal and are slidably mounted on the plastic cover 12B. The plastic cover 12B restricts the contact between the first inner slide rail 3 and the second inner slide rail 4 and the metal frame 12A. That is, the contact between the first outer slide rail 1 and the first inner slide rail 3 is plastic and metal, and the contact between the second outer slide rail 2 and the second inner slide rail 4 is also plastic and metal, avoiding metal-to-metal contact. During sliding, this can reduce noise and increase wear resistance.

[0060] The plastic cover 12B has a positioning protrusion 125 and a buckle 123, while the metal frame 12A has a positioning hole 124. The positioning protrusion 125 extends into the positioning hole 124 to provide positioning and ensure accurate installation. The buckle 123 engages with the metal frame 12A, fixing the plastic cover 12B to the metal frame 12A. When fixing the first outer slide rail 1 and the second outer slide rail 2 to the rotating seat 50, they can be fixed to the metal frame 12A with bolts, ensuring reliable fixing and easy assembly / disassembly.

[0061] In actual use, the first outer slide rail 1 and the second outer slide rail 2 of this embodiment both include a fixedly connected metal frame 12A and a plastic cover 12B. The plastic cover 12B covers the metal frame 12A, and the inner slide rail made of metal is slidably disposed on the plastic cover 12B. The plastic cover 12B separates the metal frame 12A from the inner slide rail, which can effectively reduce noise and wear, prevent friction between metals, and the two metal frames 12A can respectively ensure the structural strength of the two outer slide rails.

[0062] like Figures 6-8 and combined Figure 4 As shown, in this embodiment, the first outer slide rail 1 and the second outer slide rail 2 are symmetrically arranged, and each also includes a base plate 122, with a first side plate 121 extending upward from one side of the base plate 122. The base plate 122 of the two outer slide rails is partially formed by a portion of the structure of the metal frame 12A and another portion by a portion of the structure of the plastic cover 12B. Similarly, the first side plate 121 of the two outer slide rails is partially formed by a portion of the structure of the metal frame 12A and another portion by a portion of the structure of the plastic cover 12B.

[0063] The first outer slide rail 1 and the second outer slide rail 2 are mounted on the rotating seat 50, forming an open-top installation space 100 on the rotating seat 50. Since there are no inwardly bent plates at the top of the two first side plates 121, the first outer slide rail 1 and the second outer slide rail 2 together form an open-top installation space 100 on the rotating seat 50. The sliding seat 60, equipped with the first inner slide rail 3 and the second inner slide rail 4, can be installed in the installation space 100 from top to bottom, making it convenient for the sliding seat 60 with the inner slide rail to be installed in the installation space 100 from top to bottom, thus facilitating installation.

[0064] Furthermore, the first inner slide rail 3 and the second inner slide rail 4 are symmetrically arranged and each includes several folded ears 342. The folded ears 342 are formed by bending from the second side plate 341 and are used to connect with the sliding seat 60 or the seat of a child safety seat. The size of the folded ears 342 is much smaller than the size of the first inner slide rail 3 and the second inner slide rail 4, making them easy to bend and forming in a single bend.

[0065] Compared to the existing sliding mechanism guide system on child safety seats, the guide system of this solution can effectively reduce the number of bends, and is easy to manufacture and low in cost.
