Description

Technical Field

[0001] This utility model relates to the field of child car safety seat technology, and in particular to a safety seat. Background Technology

[0002] Child car seats provide protection for children's safety while traveling in vehicles. Most car seats on the market are fixed to the car seat, requiring parents to bend over and reach into the car to place their child, which is inconvenient. Some child car seats now offer orientation adjustment to accommodate children of different ages for both forward and rear-facing use, making it easier for the operator to place the child. However, during seat rotation, the seat itself shifts relative to the base in the fore-and-aft direction, requiring the user to provide sufficient space for rotation, thus affecting the user experience. Utility Model Content

[0003] The purpose of this invention is to provide a safety seat that does not require sufficient space for the seat body to rotate, thereby improving the user experience.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] Child safety seat, the child safety seat comprising:

[0006] Base;

[0007] A seat body having a first position and a second position relative to the base;

[0008] An actuating structure is disposed between the seat body and the base. The actuating structure is used to rotate the seat body relative to the base between a first position and a second position. The actuating structure includes a first shaft and a second shaft. The first shaft rotatably connects the base and the seat body, and the second shaft slidably connects the base and the seat body. When the seat body rotates from the first position to the second position, the first shaft and the second shaft move closer to each other and then move further apart. The seat body rotates circumferentially around the first shaft.

[0009] As an optional technical solution for the aforementioned safety seat, the seat body also has a third position symmetrical to the second position. The actuation structure further includes a third axis, which slidably connects the base and the seat body. When the seat body is placed in the first position, the third axis and the second axis are symmetrically arranged with respect to the central axis of the base. When the seat body rotates from the first position to the third position, the first axis and the third axis move closer to each other and then further apart, and the seat body rotates circumferentially around the first axis.

[0010] As an optional technical solution for the aforementioned safety seat, one of the base and the seat body is provided with a first sliding groove and a second sliding groove, and the other of the base and the seat body is provided with a second shaft and a third shaft. The second shaft is slidably disposed in the first sliding groove, and the third shaft is slidably disposed in the second sliding groove. When the rotation angle of the seat body is greater than 0° and less than 90°, the first shaft and the second shaft or the third shaft are close to each other, and the distance between the first shaft and the second shaft or the third shaft can reach the minimum distance value. When the rotation angle of the seat body is equal to 90°, the distance between the first shaft and the second shaft or the third shaft is greater than the minimum distance value.

[0011] As an optional technical solution for the aforementioned safety seat, both the first and second slides are straight tracks. When the seat body rotates from the first position to the second position, the second shaft slides into the first slide, the second shaft and the first shaft move closer to each other and then move further apart, and the third shaft slides out of the second slide. When the seat body rotates from the first position to the third position, the third shaft slides into the second slide, the second shaft slides out of the first slide, and the third shaft and the first shaft move closer to each other and then move further apart.

[0012] As an optional technical solution for the aforementioned safety seat, one end of the first groove extends through the edge of the seat body or the base; one end of the second groove extends through the edge of the seat body or the base.

[0013] As an optional technical solution for the aforementioned safety seat, when the seat body is placed in the first position, the first slide groove and the second slide groove are symmetrically arranged with respect to the central axis of the base. The first slide groove and the second slide groove are located at the rear end of the seat body or the base, and the first slide groove and the second slide groove are respectively inclined from the edge of the seat body or the base toward the central axis of the base.

[0014] As an optional technical solution for the aforementioned safety seat, one of the base and the seat body is provided with a guide slider and connected to the guide slider through the first shaft, and the other is provided with a guide groove. When the seat body rotates from the first position to the second position, the guide slider slides in the guide groove to form a first guide trajectory, and the seat body rotates circumferentially relative to the base; when the seat body rotates from the first position to the second position, the guide slider slides in the guide groove to form a second guide trajectory, and the seat body rotates circumferentially relative to the base.

[0015] As an optional technical solution for the aforementioned safety seat, the ratio of the length to the width of the guide groove is greater than 2.5.

[0016] As an optional technical solution for the aforementioned safety seat, one of the seat body and the base is provided with a sliding shaft, and the other of the seat body and the base is provided with a sliding groove. The sliding shaft is slidably disposed in the sliding groove. When the seat body moves from a first position to a second position, one end of the sliding groove is used to limit the rotation angle of the seat body. When the seat body moves from the first position to a third position, the other end of the sliding groove is used to limit the rotation angle of the seat body.

[0017] As an optional technical solution for the aforementioned safety seat, the sliding groove is a semi-circular groove. In the first position, the sliding groove is symmetrically arranged with respect to the central axis of the base, and the sliding shaft is located in the middle of the sliding groove. When the seat body is located in the second position, the sliding shaft is located at one end of the sliding groove. When the seat body is located in the third position, the sliding shaft is located at the other end of the sliding groove.

[0018] The beneficial effects of this utility model are:

[0019] The safety seat provided by this utility model has a seat body and a base that are rotatably connected via a first axis and slidably connected via a second axis. During the process of the seat body rotating from a first position to a second position, the seat body rotates circumferentially around the first axis. The cooperation of the first and second axes causes the seat body to form a movement trajectory, thereby changing the orientation of the seat body and making it easier to put the child on the seat body. During the rotation, the first and second axes move closer to each other and then further away from each other, so that the seat body does not have a certain amount of offset in the front-back direction relative to the base. Therefore, the user does not need to provide enough space for the installation of the safety seat to achieve the rotation of the seat body, thus improving the user experience.

[0039] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0040] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0041] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0042] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0043] The following descriptions of directions such as front, back, left, right, up, and down are all defined with reference to the direction observed by the child in the car seat when the car seat is installed facing forward in the car seat. The purpose is only to clearly illustrate the relative positional relationship of the various components in the car seat.

[0044] Referring to the accompanying drawings, this embodiment provides a safety seat, which includes a base 1, a seat body 2, and an actuating structure. The seat body 2 has a first position and a second position relative to the base 1. The actuating structure is disposed between the seat body 2 and the base 1, and is used to rotate the seat body 2 relative to the base 1 between the first position and the second position. The actuating structure includes a first shaft 41 and a second shaft 42. The first shaft 41 rotatably connects the base 1 and the seat body 2, and the second shaft 42 slidably connects the base 1 and the seat body 2. When the seat body 2 rotates from the first position to the second position, the first shaft 41 and the second shaft 42 move closer to each other and then further away from each other, and the seat body 2 rotates circumferentially around the first shaft 41.

[0045] The seat body 2 and the base 1 are rotatably connected via a first shaft 41, and slidably connected via a second shaft 42. During the process of the seat body 2 rotating from the first position to the second position, the seat body 2 rotates circumferentially around the first shaft 41. The cooperation of the first shaft 41 and the second shaft 42 causes the seat body 2 to form a movement trajectory to change the orientation of the seat body 2, making it easier to put the child on the seat body 2. During the rotation, the first shaft 41 and the second shaft 42 move closer to each other and then move further away from each other, so that the seat body 2 does not have a certain amount of offset relative to the base 1 in the front-back direction. Therefore, the user does not need to provide enough space for the installation of the safety seat to achieve the rotation of the seat body 2, which improves the user experience.

[0046] Specifically, the seat body 2 includes a supporting main body and a supporting member 20. The supporting member 20 is located at the bottom of the supporting main body and engages with it. A support member 3 is provided on the base 1. The seat body 2 is connected to the base 1 via the supporting member 20, specifically to the support member 3 on the base 1. The supporting member 20 is located between the support member 3 and the supporting main body. The supporting main body can be integrally formed with the supporting member 20 or separately formed; the two can be assembled or disassembled. This allows for the selection of different supporting main bodies to engage with the supporting member 20 and be installed on the base 1 according to usage requirements. The supporting main body can specifically be… Figure 1 , Figure 2 and Figure 5 The baby carrier 21 shown is suitable for use by younger infants and toddlers, and can also be used for... Figure 3 , Figure 4 and Figure 6 The safety seat 22 shown is designed for use by older children.

[0047] When the seat body 2 is in the first position, it faces forward or backward; when the seat body 2 is switched to the second position, it faces left or right.

[0048] Specifically, see Figures 1 to 2 As shown, the main support structure of the seat body 2 is the basket 21. Figure 1 In the state shown, basket 21 is in the first position and facing backward; Figure 2 In the indicated state, the carrier 21 is in the second position, facing to the right. Thus, when the child safety seat is installed in the car seat, when the carrier 21 is switched to the second position, the carrier 21 faces the car door frame, making it easier for parents to place the child in the carrier 21 and secure it to the carrier 21.

[0049] Similarly, see Figures 3 to 4 As shown, the main support of the seat body 2 is the safety seat 22, which is suitable for older children. Figure 3 In the indicated state, safety seat 22 is in the first position and facing forward; Figure 4 In the indicated position, the safety seat 22 is in the second position, facing to the right and towards the car door frame, making it convenient for parents to place the child on the safety seat 22 and restrain them there.

[0050] In some embodiments, such as Figure 7 and Figure 9As shown, the seat body 2 also has a third position symmetrically arranged with respect to the second position. The seat body 2 can also be moved to the third position via an actuating mechanism. The orientation of the seat body 2 in the third position is opposite to that in the second position. That is, when the seat body 2 is in the second and third positions, the orientation of the seat body 2 is to the right and to the left, respectively. This allows the user to easily select whether to switch the seat body 2 to the second or third position based on the installation position of the child safety seat in the car seat, thereby facing the corresponding side door.

[0051] Optionally, such as Figures 7 to 10 As shown, the actuation structure also includes a third shaft 43, which slidably connects the base 1 and the seat body 2. When the seat body 2 is in the first position, the third shaft 43 and the second shaft 42 are symmetrically arranged with respect to the central axis M1 of the base 1. As the seat body 2 rotates from the first position to the third position, the first shaft 41 and the third shaft 43 move closer to each other and then further apart, and the seat body 2 rotates circumferentially around the first shaft 41. The cooperation of the first shaft 41 and the third shaft 43 allows the seat body 2 to form a movement trajectory to change the orientation of the seat body 2, making it easier to place and remove the child on the seat body 2. Furthermore, during the rotation, the first shaft 41 and the third shaft 43 move closer to each other and then further apart, ensuring that the seat body 2 does not have a certain amount of offset in the front-back direction relative to the base 1. This eliminates the need for the user to provide sufficient space for the installation of the safety seat in order to achieve the rotation of the seat body 2, thus improving the user experience.

[0052] Figure 7 and Figure 8 This is a schematic diagram of the seat body 2 in the first position. Figure 9 and Figure 10 This is a schematic diagram showing the seat body 2 positioned in the second or third position. (Example) Figures 7 to 10 As shown, when the seat body 2 rotates from the first position to the second position, it forms a first movement trajectory; when the seat body 2 rotates from the first position to the third position, it forms a second movement trajectory. The first movement trajectory and the second movement trajectory do not intersect, and the seat body 2 remains in the same plane as it moves along both the first and second movement trajectories. Alternatively, the first and second movement trajectories may be located in the same horizontal plane.

[0053] When the seat body 2 rotates to the second or third position, it rotates from a forward-facing position to a left- or right-facing position, preferably facing the vehicle door, i.e., the seat body 2 rotates 90°. In some embodiments, one of the base 1 and the seat body 2 is provided with a first slide groove 44 and a second slide groove 45, and the other of the base 1 and the seat body 2 is provided with a second shaft 42 and a third shaft 43. The second shaft 42 is slidably disposed in the first slide groove 44, and the third shaft 43 is slidably disposed in the second slide groove 45. When the rotation angle of the seat body 2 is greater than 0° and less than 90°, the first shaft 41 and the second shaft 42 or the third shaft 43 are close to each other, and the distance between the first shaft 41 and the second shaft 42 or the third shaft 43 can reach the minimum distance value. When the rotation angle of the seat body 2 is equal to 90°, the distance between the first shaft 41 and the second shaft 42 or the third shaft 43 is greater than the minimum distance value. When the seat body 2 rotates to make the first shaft 41 and the second shaft 42 or the third shaft 43 reach the minimum distance value, the angle of rotation of the seat body 2 is less than 90°. As the seat body 2 continues to rotate to 90°, the first shaft 41 and the second shaft 42 or the third shaft 43 move away from each other so that the seat body 2 can rotate to the second position or the third position.

[0054] Both the first slide groove 44 and the second slide groove 45 are straight grooves. When the seat body 2 moves along the first moving trajectory, the seat body 2 is axially fixed and rotates relative to the base 1. The second shaft 42 slides into the first slide groove 44, and the third shaft 43 slides out of the second slide groove 45. The second shaft 42 and the first shaft 41 approach each other and then move away from each other, forming the first moving trajectory. This does not affect the rotation of the seat body 2 relative to the base 1, allowing the seat body 2 to move from the first position to the second position. When the seat body 2 moves along the second moving trajectory, the seat body 2 is axially fixed and rotates relative to the base 1. The third shaft 43 slides into the second slide groove 45, and the second shaft 42 slides out of the first slide groove 44. The third shaft 43 and the first shaft 41 approach each other and then move away from each other, forming the second moving trajectory. This does not affect the rotation of the seat body 2 relative to the base 1, allowing the seat body 2 to move from the first position to the third position. Optionally, the first slide groove 44 and the second slide groove 45 are provided on the seat body 2, and the second shaft 42 and the third shaft 43 are provided on the base 1. The seat body 2 and the base 1 are rotatably connected by the first shaft 41, and the second shaft 42 and the third shaft 43 can rotate along their own axes to ensure that the seat body 2 can rotate smoothly.

[0055] like Figure 7 and Figure 11As shown, one end of the first sliding groove 44 penetrates through the edge of the seat body 2 or the base 1 so that the second shaft 42 slides out of the first sliding groove 44, and one end of the second sliding groove 45 penetrates through the edge of the seat body 2 or the base 1 so that the third shaft 43 slides out of the second sliding groove 45, and the matching structure is simple. When the seat body 2 is in the first position, the first sliding groove 44 and the second sliding groove 45 are symmetrically arranged with respect to the base central axis M1 of the base 1. The first sliding groove 44 and the second sliding groove 45 are arranged at the rear end of the seat body 2 or the base 1, and the first sliding groove 44 and the second sliding groove 45 are respectively inclined from the edge of the seat body 2 or the base 1 towards the base central axis M1 of the base 1. In some other embodiments, the first sliding groove 44 and the second sliding groove 45 can also be arranged at the front end of the seat body 2 or the base 1, and are symmetrically arranged respectively with the first sliding groove 44 and the second sliding groove 45 arranged at the rear end.

[0056] In some embodiments, such as Figures 8 to 10 As shown, the base 1 has a base axis a, the seat body 2 has a seat central axis M2 extending along the longitudinal direction of the seat body 2 and a seat axis b perpendicular to and intersecting with the seat central axis M2. The seat axis b is parallel to the base axis a. When the seat body 2 is in the first position, the seat axis b coincides with the base axis a. When the seat body 2 is in the second position or the third position, the base axis a intersects with the seat central axis M2, and the distance L between the base axis a and the seat axis b > 0, for example, 50mm < L < 250mm. When the seat body 2 is in the second position or the third position, the seat body 2 does not generate displacement in the front and rear directions, and extends a distance of L in the left or right direction. When the user places a child on the seat body 2 or takes the child off the seat body 2, there is no need to bend down or stretch the body into the car for operation, and it is more convenient to use.

[0057] When the seat body 2 moves from the first position to the second position, a first guiding trajectory is formed. When the seat body 2 moves from the first position to the third position, a second guiding trajectory is formed. The first guiding trajectory and the second guiding trajectory are symmetrically arranged. Since the third position and the second position are symmetrically arranged, the first guiding trajectory and the second guiding trajectory are symmetrically arranged to ensure that the seat body 2 can move smoothly and stably to the second position or the third position. Optionally, the first guiding trajectory and the second guiding trajectory are symmetrically arranged with respect to the base central axis M1 of the base 1, so that the position states of the seat body 2 in the second position and the third position are symmetric with respect to the base central axis M1 of the base 1. The first guiding trajectory and the first moving trajectory cooperate to enable the seat body 2 to extend a distance of L in the left direction at the second position, and the second guiding trajectory and the second moving trajectory cooperate to enable the seat body 2 to extend a distance of L in the right direction at the third position.

[0058] Both the first and second guide trajectories are straight lines, and the first guide trajectory connects with the second guide trajectory. Both the first and second guide trajectories are independent motion trajectories; that is, the first guide trajectory does not intersect with the first movement trajectory, and the second guide trajectory does not intersect with the second movement trajectory. Optionally, such as... Figure 12 As shown, one of the seat body 2 and the base 1 is provided with a guide slider 53 and connected to the guide slider 53 through a first shaft 41, while the other is provided with a guide groove 52. When the seat body 2 moves along a first moving trajectory, the guide slider 53 slides in the guide groove 52 to form a first guide trajectory, and the seat body 2 rotates circumferentially relative to the base 1. When the seat body 2 moves along a second moving trajectory, the guide slider 53 slides in the guide groove 52 to form a second guide trajectory, and the seat body 2 rotates circumferentially relative to the base 1. The guide groove 52 extends in the left-right direction and is symmetrically arranged with respect to the base center axis M1 of the base 1. When the seat body 2 is in the first position, the guide slider 53 is in the middle position of the guide groove 52. When the seat body 2 moves from the first position to the second position, the guide slider 53 slides towards one end of the guide groove 52. When the seat body 2 moves from the first position to the third position, the guide slider 53 slides towards the other end of the guide groove 52.

[0059] Optionally, the seat body 2 is provided with a guide slider 53, and the base 1 is provided with a guide groove 52. The seat body 2 and the guide slider 53 are rotatably connected via a first shaft 41. The base 1 is provided with a support member 3, and the guide groove 52 is disposed on the support member 3. The guide slider 53 has an I-shaped structure, with both ends of the guide slider 53 slidably connected to the guide groove 52, and the middle part of the guide slider 53 rotatably connected to the seat body 2 via the first shaft 41.

[0060] The length-to-width ratio of the guide groove 52 is greater than 2.5 to reduce the amount of swaying when the seat body 2 rotates.

[0061] The aforementioned support member 3 is disc-shaped. The support member 3 can rotate on the base 1 around the base axis a extending in the vertical direction, so that the support member 3 can rotate 180° or 360° as a whole, so that the seat body 2 can switch between the forward facing direction and the backward facing direction. The center of the aforementioned first slide groove 44 and second slide groove 45 is also offset from the center of the support member 3.

[0062] Figure 13 and Figure 14 This is a diagram showing the intermediate position of the seat body 2 as it rotates from the first position to the second or third position. Optionally, as shown... Figures 12 to 14As shown, one of the seat body 2 and the base 1 is provided with a sliding shaft 54, and the other of the seat body 2 and the base 1 is provided with a sliding groove 55. The sliding shaft 54 ​​is slidably disposed in the sliding groove 55. When the seat body 2 moves from the first position to the second position, one end of the sliding groove 55 is used to limit the rotation angle of the seat body 2. When the seat body 2 moves from the first position to the third position, the other end of the sliding groove 55 is used to limit the rotation angle of the seat body 2 to prevent the seat body 2 from rotating excessively. Optionally, the sliding groove 55 is a semi-circular groove. When the seat body 2 is placed in the first position, the sliding groove 55 is symmetrically arranged with respect to the base central axis M1 of the base 1, and the sliding shaft 54 ​​is placed in the middle of the sliding groove 55. When the seat body 2 is placed in the second position, the sliding shaft 54 ​​is placed at one end of the sliding groove 55. When the seat body 2 is placed in the third position, the sliding shaft 54 ​​is placed at the other end of the sliding groove 55. When the seat body 2 is in the second or third position, the sliding groove 55 limits the seat body 2 to only rotate 90°, which can meet the user's needs and make it convenient for the user to take the child out of the car seat.

[0063] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
