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 safety seats protect children while the vehicle is in motion, providing effective protection for their safety as passengers. Currently, safety seats are typically fixed to car seats, requiring parents to bend over and lean their upper bodies into the car to place their children in them, which is inconvenient.

[0003] To address these issues, some car seats now offer orientation adjustment, allowing parents to rotate the seat to face the car door before placing the child in it. However, this still requires parents to lean into the car to operate the seat, making it somewhat inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a safety seat that allows parents to place their child in the seat without having to lean their upper body into the car.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] Child safety seats, including:

[0007] Base;

[0008] A seat body having a first position and a second position relative to the base;

[0009] An actuating structure is disposed between the base and the seat body, including a first shaft, one end of which is movably connected to the base, and the other end is fixedly connected to the seat body and is eccentrically disposed relative to the seat body;

[0010] When the seat body is in the first position, the orientation of the seat body is the first direction; when the seat body moves to the second position via the actuating structure, the seat body moves along the first moving trajectory, the axis of the first shaft moves relative to the base and the seat body rotates circumferentially, the central axis of the seat body deviates from the central axis when the seat body is in the first position, and the orientation of the seat body is a second direction different from the first direction.

[0011] Optionally, the actuation structure further includes a linkage plate, which is movably disposed on the base. One end of the first shaft is rotatably connected to the linkage plate, and the linkage plate can limit the movement trajectory of the first shaft so that the seat body moves along the first movement trajectory.

[0012] Optionally, the actuating structure further includes a limiting component disposed between the base and the linkage plate, the limiting component being able to limit the movement trajectory of the linkage plate.

[0013] Optionally, the limiting component includes:

[0014] The first connecting rod is hinged at one end to the base and at the other end to the linkage plate;

[0015] The second connecting rod is arranged parallel to and spaced apart from the first connecting rod, with one end hinged to the base and the other end hinged to the linkage plate.

[0016] Optionally, the actuation structure further includes a force transmission component, which is disposed on the linkage plate and connected to both the first shaft and the limiting component, so that the first shaft can drive the limiting component to move when it rotates around its own axis.

[0017] Optionally, the force transmission component includes:

[0018] The first gear is fixedly connected to the first shaft;

[0019] The second gear is rotatably mounted on the linkage plate and meshes with the first gear.

[0020] The third gear is rotatably mounted on the linkage plate and meshes with the second gear. The third gear is connected to the limiting component to drive the limiting component to move.

[0021] Optionally, the limiting component includes:

[0022] The first connecting rod is hinged at one end to the base and fixedly connected at the other end to the third gear;

[0023] The second connecting rod is arranged parallel to and spaced apart from the first connecting rod, with one end hinged to the base and the other end hinged to the linkage plate.

[0024] Optionally, there is a gap between the first gear and the base; and / or

[0025] There is a gap between the second gear and the base.

[0026] Optionally, the seat body also has a third position symmetrically arranged with respect to the second position. When the seat body switches between the first position and the third position, the seat body moves along a second trajectory, and the axis of the first axis moves relative to the base and the seat body rotates circumferentially.

[0027] Optionally, the safety seat further includes a base, the base being rotatably disposed on the base.

[0028] The beneficial effects of this utility model are:

[0029] This car seat can be installed inside a car. In its normal state, the seat is in its first position relative to the base, facing a first direction, which is either in front of or behind the car's direction of travel. When a parent needs to place the child in the seat from outside the car, they switch the seat to a second position. In this position, the seat faces a second direction, which is towards the car door. The seat's central axis is offset, and part of the seat extends beyond the door, allowing the parent to place the child directly in the seat without needing to lean into the car. The seat can then be switched back to the first position, making the process more convenient and user-friendly. Attached Figure Description

[0048] 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.

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.

[0052] See Figures 1-4 ,as well as Figure 8 This embodiment provides a safety seat that is more convenient to use.

[0053] Specifically, in this embodiment, the safety seat includes a base 1, a seat body 2, and an actuation structure 3.

[0054] The seat body 2 has a first position and a second position relative to the base 1.

[0055] The actuation structure 3 is disposed between the base 1 and the seat body 2, and includes a first shaft 31. One end of the first shaft 31 is movably connected to the base 1, and the other end is fixedly connected to the seat body 2 and is eccentrically disposed relative to the seat body 2.

[0056] When the seat body 2 is in the first position, the orientation of the seat body 2 is the first direction; when the seat body 2 is moved to the second position by the actuation structure 3, the seat body 2 moves along the first moving trajectory, the axis of the first shaft 31 moves relative to the base 1 and the seat body 2 rotates circumferentially, the central axis of the seat body 2 deviates from the central axis when the seat body 2 is in the first position, and the orientation of the seat body 2 is a second direction different from the first direction.

[0057] Specifically, see Figure 1 and Figure 2At this time, the seat body 2 is in the first position relative to the base 1, and the projections of the seat body 2 and the base 1 overlap. The orientation of the seat body 2 is the first direction. In actual use, the orientation of the seat body 2 is either in front or behind the direction of vehicle travel.

[0058] See Figure 3 At this time, the seat body 2 is between the first position and the second position. When the seat body 2 moves to the second position via the actuation structure 3, the seat body 2 moves along the first movement trajectory, the axis of the first shaft 31 moves relative to the base 1 and the seat body 2 rotates circumferentially, and the central axis of the seat body 2 deviates from the central axis when the seat body 2 is in the first position, so there will be misalignment between the seat body 2 and the base 1.

[0059] See Figure 4 At this time, the seat body 2 is in the second position relative to the base 1; at this time, the orientation of the seat body 2 changes, and the central axis of the seat body 2 deviates from the central axis when the seat body 2 is in the first position.

[0060] When the car seat is installed in a car, under normal conditions, the seat body 2 is in the first position relative to the base 1, facing a first direction, which is either in front or behind the direction of travel. When a parent needs to place the child on the seat body from outside the car, the seat body 2 is switched to the second position. In this position, the seat body 2 faces a second direction, which is towards the car door. At this time, the central axis of the seat body 2 is offset, and part of the seat body 2 extends outside the car door. Parents can place the child directly on the seat body 2 without having to lean their upper body into the car. Then, the seat body 2 is switched back to the first position, making the operation more convenient and user-friendly.

[0061] Further, see Figure 1 The safety seat also includes a base 5, with the base 1 rotatably mounted on the base 5.

[0062] Specifically, base 5 is used for mounting on car seats.

[0063] Further, see Figure 5 and Figure 6 The seat body 2 also has a third position symmetrically arranged with respect to the second position. When the seat body 2 switches between the first position and the third position, the seat body 2 moves along the second trajectory, and the axis of the first shaft 31 moves relative to the base 1 and the seat body 2 rotates circumferentially.

[0064] With this configuration, users can install the child safety seat either near the left door or near the right door in the second row, as needed.

[0065] For example, withFigure 4 Taking the indicated orientation as an example, this child safety seat is installed in the second row near the right-side door. When placing the child in the car, the parent switches the seat body 2 to the desired position. Figure 4 The second position shown is in which the seat body 2 faces to the right and can extend out from the right door.

[0066] For example, with Figure 6 Taking the indicated orientation as an example, this child safety seat is installed in the second row near the left-side door. When placing the child in the car, the parent switches the seat body 2 to the desired position. Figure 6 The third position shown is where the seat body 2 faces to the left and can extend out from the left door.

[0067] Specifically, see Figures 7-10 In this embodiment, the actuation structure 3 also includes a linkage plate 32, which is movably disposed on the base 1. One end of the first shaft 31 is rotatably connected to the linkage plate 32. The linkage plate 32 can restrict the movement trajectory of the first shaft 31 so that the seat body 2 moves along the first movement trajectory.

[0068] When the seat body 2 switches from the first position to the second position, the seat body 2 is rotated. Since the other end of the first shaft 31 is fixedly connected to the seat body 2, the first shaft 31 moves with the seat body 2. Since the linkage plate 32 can restrict the movement trajectory of the first shaft 31, the seat body 2 moves along the first movement trajectory to switch to the second position.

[0069] Of course, in this embodiment, the linkage plate 32 can also restrict the movement trajectory of the first axis 31 so that the seat body 2 moves along the second trajectory.

[0070] When the seat body 2 is switched from the first position to the third position, the seat body 2 is rotated. Since the other end of the first shaft 31 is fixedly connected to the seat body 2, the first shaft 31 moves with the seat body 2. Since the linkage plate 32 can restrict the movement trajectory of the first shaft 31, the seat body 2 moves along the second trajectory to switch to the third position.

[0071] Specifically, see Figure 8 and Figure 9 In order to restrict the movement trajectory of the linkage plate 32, thereby restricting the movement trajectory of the first axis 31, in this embodiment, the actuation structure 3 further includes a restriction component 33, which is disposed between the base 1 and the linkage plate 32. The restriction component 33 can restrict the movement trajectory of the linkage plate 32.

[0072] Specifically, see Figure 9 and Figure 10 The limiting component 33 includes a first link 331 and a second link 332.

[0073] One end of the first connecting rod 331 is hinged to the base 1, and the other end is hinged to the linkage plate 32.

[0074] The second link 332 is arranged parallel to and spaced apart from the first link 331. One end of the second link 332 is hinged to the base 1, and the other end is hinged to the linkage plate 32.

[0075] Furthermore, in order to connect the linkage plate 32 and the limiting component 33, the actuation structure 3 also includes a force transmission component 34. The force transmission component 34 is disposed on the linkage plate 32 and is connected to both the first shaft 31 and the limiting component 33, so that the first shaft 31 can drive the limiting component 33 to move when it rotates around its own axis.

[0076] Specifically, in this embodiment, the force transmission component 34 includes a first gear 341, a second gear 342, and a third gear 343.

[0077] The first gear 341 is fixedly connected to the first shaft 31.

[0078] The second gear 342 is rotatably mounted on the linkage plate 32 and meshes with the first gear 341.

[0079] The third gear 343 is rotatably mounted on the linkage plate 32 and meshes with the second gear 342. The third gear 343 is connected to the limiting component 33 to drive the limiting component 33 to move.

[0080] Specifically, in this embodiment, the upper end of the first shaft 31 is fixedly connected to the pad 4, and the pad 4 is fixedly disposed on the lower surface of the seat body 2.

[0081] Further, see Figure 7 , Figure 11 and Figure 12 The pad 4 is provided with a slot 41, and the upper end of the first shaft 31 is engaged in the slot 41. In order to prevent relative rotation between the pad 4 and the first shaft 31, a first anti-rotation plane 311 is provided on the outer side of the first shaft 31, and a second anti-rotation plane 411 is provided on the inner surface of the slot 41. The first anti-rotation plane 311 and the second anti-rotation plane 411 abut against each other to restrict relative rotation between the pad 4 and the first shaft 31.

[0082] Alternatively, the outer surface of the first shaft 31 is provided with a plurality of first anti-rotation planes 311 at intervals, and the inner surface of the slot 41 is provided with a plurality of second anti-rotation planes 411, with the first anti-rotation planes 311 and the second anti-rotation planes 411 being provided in a one-to-one correspondence.

[0083] Specifically, the number of the first anti-rotation planes 311 can be two, three, four, or more, depending on the needs, and no further restrictions are imposed here. The number of the second anti-rotation planes 411 is the same as the number of the first anti-rotation planes 311.

[0084] To avoid excessive friction between the force transmission component 34 and the base 1, which could affect the movement of the force transmission component 34, a gap exists between the first gear 341 and the base 1; and / or

[0085] There is a gap between the second gear 342 and the base 1.

[0086] Specifically, there is a gap between the lower end of the first shaft 31 and the base 1. A second gear mounting shaft 321 is fixedly mounted on the linkage plate 32, and the second gear 342 is rotatably sleeved on the second gear mounting shaft 321. There is a gap between the lower end of the second gear mounting shaft 321 and the base 1.

[0087] A third gear mounting shaft 322 is also fixedly installed on the linkage plate 32, and the third gear 343 is rotatably sleeved on the third gear mounting shaft 322.

[0088] In order for the seat body 2 to obtain stable support when the seat body 2 remains stationary, the lower surface of the third gear 343 contacts the upper surface of the base 1 and the third gear 343 can move relative to the base 1, and the upper surface of the third gear 343 contacts the lower surface of the linkage plate 32 and the third gear 343 can rotate relative to the linkage plate 32.

[0089] More specifically, one end of the first connecting rod 331 is hinged to the base 1, and the other end is fixedly connected to the third gear 343.

[0090] The second link 332 is arranged parallel to and spaced apart from the first link 331, with one end hinged to the base 1 and the other end hinged to the linkage plate 32.

[0091] Specifically, to achieve a fixed connection between the other end of the first connecting rod 331 and the third gear 343, the lower end of the third gear 343 is provided with a clearance notch 3431 to avoid the first connecting rod 331. The other end of the first connecting rod 331 passes through the clearance notch 3431 and is fixedly connected to the third gear 343 through a connector. Optionally, the connector is a pin. Furthermore, to provide double limiting for the other end of the first connecting rod 331, the other end of the first connecting rod 331 can also move through the third gear mounting shaft 322.

[0092] To enable the hinge connection between the other end of the second link 332 and the linkage plate 32, a second link connecting shaft 324 is also fixedly installed on the linkage plate 32. Specifically, the upper end of the second link connecting shaft 324 is fixed to the linkage plate 32, and the lower end moves through the other end of the second link 332, and the lower end of the second link connecting shaft 324 can move relative to the base 1.

[0093] The other end of the second link 332 is rotatably connected to the lower end of the second link connecting shaft 324.

[0094] Since the first link 331 and the second link 332 are located at the two ends of the linkage plate 32 respectively, in order to ensure the balance of the linkage plate 32 and to ensure that the seat body 2 can obtain stable support when it remains stationary, a support block 3241 is sleeved on the second link connecting shaft 324. The support block 3241 is located between the linkage plate 32 and the second link 332 to support the linkage plate 32.

[0095] For example, when the seat body 2 is in the first position, such as Figure 1 and Figure 2 As shown, the orientation of the seat body 2 is in the first direction; the states of the linkage plate 32 and the limiting component 33 are as shown in Figure 7. Figure 8 As shown.

[0096] When seat body 2 needs to be switched from the first position to Figure 4 In the second position shown, the parent's hand is placed on the seat body 2 and along... Figure 2 As shown, the seat body 2 rotates in the first clockwise direction. Simultaneously, because one end of the first shaft 31 is movably connected to the base 1, and the other end of the first shaft 31 is fixedly connected to the seat body 2 and eccentrically positioned relative to the seat body 2, the seat body 2 moves along the first trajectory under the constraint of the first shaft 31. The actuating structure 3 then... Figure 3 The state shown eventually stabilizes at... Figure 4 The state shown.

[0097] Specifically, during the movement of the seat body 2 from the first position to the second position, the first shaft 31 moves with the seat body 2. The first gear 341, fixed on the first shaft 31, rotates around the first shaft 31 in a first clockwise direction. The first gear 341 meshes with the second gear 342, thereby driving the second gear 342 to rotate around the second gear mounting shaft 321 in a second clockwise direction. The second gear 342 meshes with the third gear 343. However, since the first connecting rod 331 passes through the clearance notch 3431 on the third gear 343, the third gear 343 will not rotate around the third gear mounting shaft 322 under the restriction of the first connecting rod 331. The second gear 342 will eventually drive the first connecting rod 331 to rotate relative to the base 1 in a first clockwise direction. Under the movement of the limiting component 33, the seat body 2 moves to the second position along the first trajectory.

[0098] When seat body 2 needs to be switched from the first position to Figure 6 In the second position shown, the parent's hand is placed on the seat body 2 and along... Figure 2As shown, the seat body 2 rotates in the second clockwise direction. Simultaneously, because one end of the first shaft 31 is movably connected to the base 1, and the other end of the first shaft 31 is fixedly connected to the seat body 2 and eccentrically positioned relative to the seat body 2, the seat body 2 moves along the second trajectory under the constraint of the first shaft 31. The actuating structure 3 then... Figure 5 The state shown eventually stabilizes at... Figure 6 The state shown.

[0099] Specifically, during the movement of the seat body 2 from the first position to the third position, the first shaft 31 moves with the seat body 2. The first gear 341, fixed on the first shaft 31, rotates around the first shaft 31 in a second clockwise direction. The first gear 341 meshes with the second gear 342, thereby driving the second gear 342 to rotate around the second gear mounting shaft 321 in a first clockwise direction. The second gear 342 meshes with the third gear 343. However, since the first connecting rod 331 passes through the clearance notch 3431 on the third gear 343, the third gear 343 will not rotate around the third gear mounting shaft 322 under the restriction of the first connecting rod 331. The second gear 342 will eventually drive the first connecting rod 331 to rotate relative to the base 1 in a second clockwise direction. Under the movement of the limiting component 33, the seat body 2 moves to the second position along the first trajectory.
