Description

Technical Field

[0001] This utility model relates to the field of automotive safety products technology, and more specifically, to a side-sliding structure and a child safety seat. Background Technology

[0002] The child safety seat base features a sliding mechanism on its rotating disc. When the disc rotates the seat back to the left or right, the sliding mechanism causes the seat back to extend outwards from the base, achieving a cantilevered sliding position. However, the existing sliding mechanism has a weak connection to the rotating disc. After sliding out, under the pressure of the seat back and passenger, the sliding mechanism is prone to tilting relative to the rotating disc. Furthermore, during sudden braking, the sliding mechanism can generate a forward flipping force relative to the rotating disc, causing it to tilt and affecting the riding experience and comfort. Utility Model Content

[0003] To address at least one of the aforementioned problems, this utility model first provides a side-sliding structure, comprising a rotating disk and a side-sliding mechanism that are slidably connected to each other. The rotating disk is adapted to be connected to a seat base, and the side-sliding mechanism is adapted to be connected to a seat back. One end of the side-sliding mechanism is adapted to extend out of the rotating disk, and a slide rail reinforcing plate is fixedly installed on the rotating disk. Whether the side-sliding mechanism is in its extended position or in its initial state, the slide rail reinforcing plate is adapted to block the tilting of the side-sliding mechanism.

[0004] Optionally, at least two slide rail reinforcing plates are provided at intervals along the sliding direction of the side sliding mechanism. When the side sliding mechanism is in an extended state or not in an extended state, it is suitable to cooperate with the slide rail reinforcing plate at the corresponding position.

[0005] Optionally, the side-sliding mechanism includes a sliding base plate and a backrest mounting plate fixedly connected to each other. The sliding base plate is slidably connected to the rotating disk, and the backrest mounting plate is connected to the backrest. The backrest mounting plate is made of metal, and the slide rail reinforcing plate is adapted to cooperate with the backrest mounting plate.

[0006] Optionally, a mating reinforcing plate is fixedly installed on the chair back mounting plate. The mating reinforcing plate is made of metal, and the slide rail reinforcing plate is adapted to prevent the mating reinforcing plate from warping.

[0007] Optionally, the mating reinforcing plate is located on the outer wall of the backrest mounting plate and near the rear of the seat base.

[0008] Optionally, the slide rail reinforcing plate includes a mounting base plate, an extension plate, and a limiting top plate that are fixedly connected in sequence. The mounting base plate and the limiting top plate are located at the upper and lower ends of the extension plate, respectively. The mounting base plate is fixedly connected to the rotating disk, and the mating reinforcing plate is adapted to be located directly below the limiting top plate.

[0009] Optionally, the top of the rotating disk is provided with a groove that extends through the rotating disk along its diameter. Two opposite groove walls are provided with slide rail channels, and the sliding base plate is slidably inserted into the slide rail channels.

[0010] Optionally, the mating reinforcing plate is located within the sliding channel, and the slide rail reinforcing plate is fixedly installed within the slide rail channel.

[0011] Optionally, the sidewall of the sliding base plate is provided with an elastic protrusion, and the groove wall of the slide rail channel is fixedly provided with a mating protrusion. Two mating protrusions are spaced apart along the sliding direction of the sliding base plate. When the sliding base plate is in an unextended state or in an extended state, the elastic protrusion is adapted to engage with the corresponding mating protrusion to generate a tactile sensation.

[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0013] 1. The slide rail reinforcing plate can press down on the side sliding mechanism, preventing the side sliding mechanism from tilting relative to the rotating disk due to unstable center of gravity or inertial force, thus improving the stability of the cooperation and connection between the rotating disk and the side sliding mechanism.

[0014] 2. The cooperation between the slide rail reinforcing plate and the matching reinforcing plate ensures the strength of the rotating disk and the side sliding mechanism, while also ensuring the overall weight and controlling the cost.

[0015] 3. Both the backrest mounting plate and the mating reinforcement plate are made of metal. Compared with plastic, the backrest mounting plate and the mating reinforcement plate are stronger when connected. The slide rail reinforcement plate is also stronger when mated with the mating reinforcement plate.

[0016] 4. When the sliding base plate slides, it slides in a direction guided by the slide rail channel. The slide rail reinforcing plate is installed in the slide rail channel, and the matching reinforcing plate cooperates with the slide rail reinforcing plate in the slide rail channel. The slide rail reinforcing plate and the matching reinforcing plate are hidden in the slide rail channel, which does not affect the appearance of the rotating plate and the side sliding mechanism.

[0017] 5. When the side sliding mechanism is extended to its limit or not extended, the reinforcing plate cooperates with the corresponding slide rail reinforcing plate, so that the strength of the side sliding mechanism in cooperation with the rotating disk is high in different states.

[0018] 6. When manually adjusting the side sliding mechanism, when the sliding base plate extends to its limit position or retracts completely to its initial position, the elastic protrusion will form an interference fit with the corresponding matching protrusion, generating a tactile sensation. This allows the operator to intuitively feel that the adjustment is in place, preventing excessive movement from affecting the lifespan of the components.

[0019] In addition, this utility model provides a child safety seat, including the side-sliding structure described above.

[0020] Compared to existing technologies, the child safety seat described in this utility model has the same advantages as the aforementioned side-sliding structure compared to existing technologies, which will not be repeated here. Attached Figure Description

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the following description is provided in conjunction with the appendix. Figure 1-4 This application will be described in further detail.

[0027] The accompanying drawings of this utility model embodiment provide a coordinate system XYZ, where the positive direction of the X-axis represents the right, the negative direction of the X-axis represents the left, the positive direction of the Y-axis represents the front, the negative direction of the Y-axis represents the back, the positive direction of the Z-axis represents the top, and the negative direction of the Z-axis represents the bottom.

[0028] In a first aspect, this utility model embodiment provides a side-sliding structure, referring to... Figure 1 and Figure 2The side-sliding structure includes a rotating disk 1 and a side-sliding mechanism 2. The rotating disk 1 is adapted to connect with the seat base, and the side-sliding mechanism 2 is adapted to connect with the seat back. The side-sliding mechanism 2 is slidably connected to the rotating disk 1, and one end of the side-sliding mechanism 2 is adapted to extend out of the rotating disk 1. A slide rail reinforcing plate 11 is fixedly installed on the rotating disk 1. Whether the side-sliding mechanism 2 is in its extended position or in its initial state (meaning that the side-sliding mechanism has not extended out of the rotating disk 1), the slide rail reinforcing plate 11 is adapted to prevent the side-sliding mechanism 2 from tilting up. That is, the slide rail reinforcing plate 11 can press down on the side-sliding mechanism 2, so that the side-sliding mechanism 2 will not tilt up relative to the rotating disk 1 due to unstable center of gravity or inertial force, which can improve the stability of the cooperation and connection between the rotating disk 1 and the side-sliding mechanism 2.

[0029] In this embodiment, the rotating disk 1 is preferably a circular disk, and a groove 12 is formed on the top of the rotating disk 1, which extends through the rotating disk 1 along its diameter. The bottom of the side-sliding mechanism 2 is adapted to be inserted into the groove 12 and slides within the groove 12 along its extension direction. The sliding direction of the side-sliding mechanism 2 is assumed to be the front-back direction of the rotating disk 1; it is also the front-back direction of the side-sliding mechanism 2.

[0030] Reference Figures 1 to 3 The side-sliding mechanism 2 includes a sliding base plate 21 and a backrest mounting plate 22. The sliding base plate 21 is inserted into and slides within a groove 12. The backrest mounting plate 22 is fixedly connected to the sliding base plate 21 by bolts to achieve synchronous movement. The backrest mounting plate 22 is connected to the backrest, thereby driving the backrest to move synchronously with the sliding base plate 21. Decorative shells are installed on the top of the sliding base plate 21 in both the front and rear directions for decoration, and the backrest mounting plate 22 is located between the two decorative shells.

[0031] The rotating disk 1 or the sliding base plate 21 is provided with a locking mechanism (which is prior art and is not shown in the figure). The locking mechanism can lock and limit the movement of the sliding base plate 21. In this embodiment, the locking mechanism is preferably provided on the rotating disk 1.

[0032] Slide rail channels 13 are provided on both sides of the groove 12. The extension direction of the slide rail channels 13 is the same as that of the groove 12. The slide rail channels 13 extend through the rotating disk 1 along the extension direction, but do not extend through the top of the rotating disk 1. The left and right sides of the sliding base plate 21 are respectively inserted into the corresponding slide rail channels 13 and slide, thereby making it difficult for the sliding base plate 21 to detach from the rotating disk 1 in the vertical direction. In another embodiment, a damping slide rail is installed in the slide rail channel 13, and the sliding base plate 21 is connected to the damping slide rail to achieve smooth movement.

[0033] Reference Figures 1 to 3Two backrest mounting plates 22 are symmetrically spaced along the left-right direction. The following explanation uses one backrest mounting plate 22 as an example. The backrest mounting plate 22 is made of metal, as is the slide rail reinforcing plate 11. The slide rail reinforcing plate 11 is designed to cooperate with the backrest mounting plate 22, pressing it down to prevent it from warping. Furthermore, since both the slide rail reinforcing plate 11 and the backrest mounting plate 22 are made of metal, their combined strength is enhanced, resulting in higher strength when the side-sliding mechanism 2 engages with the rotating disc 1.

[0034] A mating reinforcing plate 23 is bolted to the outer wall of the backrest mounting plate 22 (i.e., the side of the two backrest mounting plates 22 that are far apart from each other in the left-right direction). The mating reinforcing plate 23 is located on the side near the rear of the backrest mounting plate 22. Thus, regardless of whether the sliding base plate 21 is extended to its limit or not extended, the slide rail reinforcing plate 11 can press against the rear of the side sliding mechanism 2, making the sliding base plate 21 less likely to tilt relative to the rotating disk 1 due to inertia or instability of the center of gravity. In another embodiment, the mating reinforcing plate 23 may not be provided. Instead, a sheet metal plate is bent into shape on the outer wall of the backrest mounting plate 22. The sheet metal plate is fixedly connected to the sliding base plate 21, and the slide rail reinforcing plate 11 presses against the sheet metal plate.

[0035] The reinforcing plate 23 is slidably inserted into the slide rail channel 13 and moves within the slide rail channel 13. The slide rail reinforcing plate 11 is installed in the slide rail channel 13, thus concealing the slide rail reinforcing plate 11 and not affecting the appearance of the rotating disk 1 and the side sliding mechanism 2.

[0036] Reference Figures 1 to 3 The slide rail reinforcing plate 11 includes a mounting base plate 14, an extension plate 15, and a limiting top plate 16, which are fixedly connected in sequence. The mounting base plate 14, extension plate 15, and limiting top plate 16 are formed by bending. The mounting base plate 14 and the limiting top plate 16 are located at the upper and lower ends of the extension plate 15, respectively, with the limiting top plate 16 located at the top of the extension plate 15. The mounting base plate 14 and the limiting top plate 16 are located on the left and right sides of the extension plate 15, respectively, with the limiting top plate 16 located on the side of the extension plate 15 closest to another slide rail reinforcing plate 11. The mounting base plate 14 is fixedly connected to the sliding base plate 21 by bolts. The cooperating reinforcing plate 23 is adapted to be located below the limiting top plate 16, and the limiting top plate 16 presses against the cooperating reinforcing plate 23. In this way, while ensuring the strength of the cooperation between the rotating disk 1 and the side sliding mechanism 2, the overall weight is also guaranteed, and the cost is controlled.

[0037] Reference Figures 1 to 3Since the reinforcing plate 23 is located on the rear side of the backrest mounting plate 22, and when the sliding base plate 21 is extended to its maximum extent, the reinforcing plate 23 is located at the middle position along the length of the slide rail channel 13, each slide rail channel 13 is provided with two slide rail reinforcing plates 11. One slide rail reinforcing plate 11 is located near the rear within the slide rail channel 13; the other slide rail reinforcing plate 11 is located at the middle position of the slide rail channel 13. When the sliding base plate 21 is not extended at all, the slide rail reinforcing plate 11 near the rear of the sliding base plate 21 presses against the reinforcing plate 23. When the sliding base plate 21 is extended to its maximum extent, the slide rail reinforcing plate 11 at the middle position of the sliding base plate 21 presses against the reinforcing plate 23. In another embodiment, two or more slide rail reinforcing plates 11 can be spaced apart along the extension direction of the slide rail channel 13. Thus, the position where the sliding base plate 21 extends to its final position is not limited to its limit; for example, the sliding base plate 21 is also considered to be in its final position even when it has not extended to its limit. In this case, the corresponding slide rail reinforcing plate 11 can also press against the mating reinforcing plate 23, improving the stability and strength of the cooperation between the side-sliding mechanism 2 and the rotating disk 1. In yet another embodiment, the length of the slide rail reinforcing plate 11 covers the sliding length of the mating reinforcing plate 23, so the mating reinforcing plate 23 can cooperate with the slide rail reinforcing plate 11 throughout the entire sliding process.

[0038] Reference Figures 2 to 4 The sliding base plate 21 has elastic protrusions 211 integrally formed on both its left and right outer side walls, and each slide rail channel 13 has a mating protrusion 131 integrally formed on its groove wall. The following description uses the elastic protrusion 211 and corresponding mating protrusion 131 on one side of the sliding base plate 21 as an example. In this embodiment, the elastic protrusion 211 is preferably located in the middle of the sliding base plate 21 near the rear; that is, the distance from the elastic protrusion 211 to the front of the sliding base plate 21 is greater than the distance from the elastic protrusion 211 to the rear of the sliding base plate 21.

[0039] The top of the sliding base plate 21 has an elongated hole 212, which is located near the elastic protrusion 211. When the sliding base plate 21 is installed, the elastic protrusion 211 is compressed and can elastically deform into the elongated hole 212 under the action of the elongated hole 212, ensuring the ease of installation of the sliding base plate 21. Each slide rail channel 13 has two mating protrusions 131. One mating protrusion 131 is located between the two slide rail reinforcing plates 11 in the same slide rail channel 13; the other mating protrusion 131 is located near the front of the sliding base plate 21. When the sliding base plate 21 is manually moved to extend it, the elastic protrusion 211 is located between the two mating protrusions 131. When the sliding base plate 21 is extended to its limit position, the elastic protrusion 211 and the mating protrusion 131 near the front of the sliding base plate 21 form an interference fit. When the sliding base plate 21 is not extended at all, the elastic protrusion 211 and the other mating protrusion 131 form an interference fit, thereby generating a limiting feel and an interference fit sensation. At this time, the operator can stop driving the sliding plate to move, preventing excessive movement from affecting the life of the parts.

[0040] The implementation principle of the side-sliding structure in this application embodiment is as follows: the slide rail reinforcing plate 11 can press against the side-sliding mechanism 2, preventing the side-sliding mechanism 2 from tilting relative to the rotating disk 1 due to instability or inertial force. The slide rail reinforcing plate 11, the mating reinforcing plate 23, and the seat back mounting plate 22 are all made of metal. The seat back mounting plate 22 and the mating reinforcing plate 23 have higher strength after being connected, and the strength of the slide rail reinforcing plate 11 and the mating reinforcing plate 23 when they are mated is also higher. When the side-sliding mechanism 2 is extended to its limit or not extended, the mating reinforcing plate 23 is mated with the corresponding slide rail reinforcing plate 11, so that the strength of the side-sliding mechanism 2 in mating with the rotating disk 1 is high in different states. In addition, when the vehicle brakes suddenly, the two sets of slide rail reinforcing plates 11 and the corresponding mating reinforcing plates 23 can disperse the overturning force generated by inertia, resulting in more uniform force distribution and improving the life of the rotating disk 1 and the side-sliding mechanism 2.

[0041] Secondly, another embodiment of the present invention provides a child safety seat, which includes the side-sliding structure described in the first aspect above.
