In order to facilitate the child to be directly placed into the safety seat outside the car, the safety seat is usually arranged on the seat close to the door of the back seat. Furthermore, in order to further improve the convenience of use, the safety seat has a function of adjusting the direction, so that the seat can be rotated to face the door.

[0053] Embodiment one

[0054] The safety seat provided in the embodiments has high speed and efficiency in adjusting position, and is convenient to operate.

[0055] The safety seat provided in the embodiments can be used in various scenes, for example, can be installed on the rear seat of a vehicle, and can also be installed on the seat of a high-speed rail or other transportation tools.

[0056] The embodiments take the safety seat installed on the rear seat of a vehicle as an example for illustration, and other cases can be referred to the embodiments. It should be noted that the safety seat is installed on the rear seat of a vehicle close to the door.

[0057] As shown in Figures 1 to 9 The safety seat includes a base frame 100, a rotating frame 200, and an actuating mechanism 300. The rotating frame 200 is provided with a seat mounting structure, which is used to mount a seat so that the seat can move with the rotating frame 200. Exemplarily, the base frame 100 is mounted on the rear seat of a vehicle, for example, the base frame 100 is detachably connected to the rear seat. Exemplarily, the base frame 100 can be directly connected to the rear seat, and can also be connected to the rear seat through other structures, for example, the base frame 100 is connected to the rear seat through a base 500.

[0058] It should be noted that the position of the base frame 100 relative to the rear seat in the length and width directions of the vehicle is not adjustable, that is, the base frame 100 is not movable in the length and width directions of the vehicle.

[0059] The rotating frame 200 is movably arranged above the base frame 100. The rotating frame 200 can rotate and translate relative to the base frame 100 under the action of an external force, so that the seat on the rotating frame 200 can be moved from a position inside the vehicle to a position extending out of the vehicle, or to a position closer to the door of the vehicle, facilitating placing a child on the seat or taking the child on the seat out.

[0060] Exemplarily, the actuating mechanism 300 comprises a rotating disc 320 arranged on the rotating frame 200 and a guide 310 arranged on the base frame 100. The rotating disc 320 is rotatable relative to the base frame 100. In the embodiment, the rotating disc 320 is arranged on the side of the rotating frame 200 facing the base frame 100, and the guide 310 is arranged on the side of the base frame 100 facing the rotating frame 200.

[0061] When the rotating frame 200 rotates under the action of an external force, the rotating disc 320 rotates synchronously, and the rotating disc 320 rolls along the guide 310 while rotating to move the center of the rotating disc 320 in the preset direction X, thereby driving the rotating frame 200 to move in the preset direction X, so that the seat on the rotating frame 200 can be moved from a position inside the vehicle to a position extending outside the vehicle or a position closer to the door. Exemplarily, for the application of the safety seat on the vehicle, the preset direction X is the left-right direction of the vehicle. Through the guidance of the guide 310, it is ensured that the rotating disc 320 and the rotating frame 200 can move in the preset direction X.

[0062] The safety seat provided in the embodiment comprises the actuating mechanism 300, which comprises the rotating disc 320 arranged on the rotating frame 200 and the guide 310 arranged on the base frame 100. When the rotating frame 200 rotates, the rotating frame 200 drives the rotating disc 320 to rotate synchronously, and the rotating disc 320 rolls along the guide 310 while rotating to move the center of the rotating disc 320 in the preset direction X, thereby driving the rotating frame 200 to move in the preset direction X while rotating, that is, the rotation and translation of the rotating frame 200 are performed simultaneously and continuously, which improves the speed and efficiency of adjusting the position of the rotating frame 200 and facilitates operation.

[0063] Moreover, the user can operate the rotating frame 200 to move closer or farther according to actual needs, which is high in flexibility. For example, the user can push the rotating frame 200 according to actual needs, so that the seat on the rotating frame 200 can be at least partially moved outside the vehicle or closer to the door of the vehicle, so that the child on the seat can be closer to the user, facilitating the user to perform corresponding operations, such as adjusting the seating space of the child, facilitating the user to hold the child, facilitating the interaction and play between the child and the user, etc., and reducing the bending amplitude of the user when placing the child on the seat or holding the child on the seat out, which is high in use convenience.

[0064] Optionally, the guide 310 extends in the preset direction X, and the two ends of the guide 310 in the preset direction X are flush with or located inside the edges of the base frame 100, so as to prevent the arrangement of the guide 310 from increasing the overall size of the safety seat.

[0065] Exemplarily, the edge of the guide 310 away from the rotating disc 320 extends to the edge of the base frame 100, so as to fill the partial gap between the base frame 100 and the rotating frame 200, reduce the probability of dust accumulation, and additionally, the guide 310 can support the rotating frame 200 in the vertical direction (i.e. the axis direction of the rotating disc 320), so that the rotating frame 200 can be more stable and the probability of shaking of the rotating frame 200 and the seat can be reduced.

[0066] Exemplarily, the rotating frame 200 is switched between the first position and the second position, i.e. the rotating frame 200 has the first position and the second position relative to the base frame 100. The rotating frame 200 is moved between the first position and the second position under the action of an external force.

[0067] Exemplarily, when the rotating frame 200 is located at the first position, the orientation of the rotating frame 200 is the first direction; when the rotating frame 200 is moved to the second position by the actuating mechanism 300, the central axis of the rotating frame 200 deviates from the central axis when the rotating frame 200 is located at the first position, and the orientation of the rotating frame 200 is the second direction different from the first direction. The first direction and the second direction can be arranged at an angle, or the first direction and the second direction are arranged perpendicularly, which is not limited in the embodiment.

[0068] In the embodiment, the first position and the second position of the rotating frame 200 are not limited, and the above-mentioned first position and second position can be set according to the required angle adjustment range of the rotating frame 200 or the seat. Wherein, Figure 1 and Figure 4 is a schematic view of the rotating frame 200 located at the first position, Figure 6 is a schematic view of the rotating frame 200 located at the second position, Figure 5 is a state diagram of the rotating frame 200 moving from the first position to the second position. For example, in the example of Figure 4 , Figure 6 Exemplarily, when the rotating frame 200 is located at the first position, the rotating frame 200 is located at the position facing the front or rear of the vehicle, so as to facilitate the safety seat to protect the child during the driving of the vehicle; when the rotating frame 200 is located at the second position, the rotating frame 200 is located at the position facing one side of the vehicle, so that the child can be closer to the user.

[0069] Optionally, the safety seat further comprises a limiting structure (not shown in the figure), which is arranged on one of the rotating frame 200 and the base frame 100, and when the rotating frame 200 is located at the second position, the limiting structure is in contact with the other one of the rotating frame 200 and the base frame 100, so as to limit the moving stroke of the rotating frame 200, so that the rotating frame 200 can be located at the second position, and the excessive movement of the rotating frame 200 is prevented. Exemplarily, the limiting structure can be a limiting block.

[0070] It should be noted that when the rotating frame 200 is located at the first position, a stop structure can be arranged to limit the continuous movement of the rotating frame 200. Of course, when the rotating frame 200 is located at the first position, the stop structure can also be unnecessary, and the present embodiment does not limit this.

[0071] Exemplarily, when the rotating frame 200 rotates from the first position to the second position, the length of the rotation disc 320 rolling along the guide 310 is equal to one quarter of the circumference of the rotation disc 320, that is, the rotating frame 200 reaches the second position after rotating 1 / 4 turn from the first position. In this way, the number of turns of the rotating frame 200 and the rotation disc 320 is less than one turn, which further improves the speed and efficiency of the rotating frame 200 moving from the first position to the second position.

[0072] Of course, it can be understood that the rotating frame 200 and the rotation disc 320 can also rotate an integer multiple of 1 / 4 turn, and can also move from the first position to the second position, and the present embodiment does not limit this.

[0073] In some optional embodiments, the rotating frame 200 further has a third position symmetrically arranged with the second position. The rotating frame 200 can move from the first position to the third position via the actuating mechanism 300, and the orientation of the rotating frame 200 when located at the second position is opposite to the orientation of the rotating frame 200 when located at the third position. Wherein, Figure 8 is a schematic view of the rotating frame 200 when located at the third position. Figure 7 is a state diagram of the rotating frame 200 moving from the first position to the third position. By arranging that the rotating frame 200 can move to the third position, the rotating frame 200 can move to the second direction and also can move to the direction opposite to the second direction. In this way, the safety seat can be arranged on the rear seat of the vehicle close to the left door, and also can be arranged on the rear seat of the vehicle close to the right door, and both can achieve the purpose of being closer to the user, have higher flexibility and versatility, and meet the needs of different application scenarios.

[0074] It should be noted that the orientation of the rotating frame 200 when located at the second position is opposite to the orientation of the rotating frame 200 when located at the third position, and the rotation direction of the rotation disc 320 when the rotating frame 200 moves from the first position to the second position is opposite to the rotation direction of the rotation disc 320 when the rotating frame 200 moves from the first position to the third position. Figure 5 R1 in the above formula represents the rotation direction of the rotating frame 200 when moving from the first position to the second position, Figure 7 R2 in the above formula represents the rotation direction of the rotating frame 200 when moving from the first position to the third position, and R1 and R2 are opposite.

[0075] For example, when the rotating frame 200 rotates from the first position to the third position, the length by which the rotating disk 320 rolls along the guide 310 is equal to one-quarter of the circumference of the rotating disk 320, that is, the rotating frame 200 reaches the third position after rotating 1 / 4 turn from the first position.

[0076] For example, the rotating frame 200 can be continuously moved from the second position to the first position and then to the third position. At this time, the length of the rotating disk 320 rolling along the guide member 310 is equal to half the circumference of the rotating disk 320.

[0077] For example, the rotating frame 200 switches between a first position and a second position.

[0078] When the rotating frame 200 is in the first position, such as Figure 4 As shown, the orthographic projection of the rotating frame 200 in the axial direction coincides with the orthographic projection of the base frame 100 in the axial direction. By aligning the rotating frame 200 and the base frame 100 in the first position, the shape of the safety seat becomes more regular, does not occupy a large space, and facilitates the mass production of the rotating frame 200 and the base frame 100.

[0079] When the rotating frame 200 is in the second position, the line connecting the center of the rotating frame 200 and the center of the base frame 100 extends along a predetermined direction X. Similarly, when the rotating frame 200 is in the third position, the line connecting the center of the rotating frame 200 and the center of the base frame 100 extends along a predetermined direction X. This positions the rotating frame 200 directly to the left or right of the base frame 100, reducing the space requirements of the rotating frame 200 in the vehicle's front-rear direction after rotation and providing better adaptability. It should be noted that the center of the rotating frame 200 is the geometric center of its cross-section, and the center of the base frame 100 is the geometric center of its cross-section. When both the rotating frame 200 and the base frame 100 are disc structures, the center is the center of the circle.

[0080] Optionally, such as Figure 5 As shown, the guide member 310 extends in a direction parallel to the preset direction X, and when the rotating frame 200 is in the first position, the center of the rotating disk 320 is located on the center line of the guide member 310. Specifically, the center of the rotating disk 320 is located on the center line of the guide member 310 perpendicular to the preset direction X. The rotating disk 320 can roll toward both ends of the guide member 310 in the preset direction X, so that the rotating frame 200 moves to the second position and the third position respectively. For example, when the rotating disk 320 rolls toward one end of the guide member 310, the rotating frame 200 moves to the second position; when the rotating disk 320 rolls toward the other end of the guide member 310, the rotating frame 200 moves to the third position.

[0081] For example, such as Figure 2As shown, the actuating mechanism 300 further comprises an auxiliary guiding structure 400 for limiting the center of the rotating disc 320 from moving away from the preset direction X, thereby ensuring that the rotating disc 320 and the rotating frame 200 can move in the preset direction X. For example, the auxiliary guiding structure 400 can limit the distance between the center of the rotating disc 320 and the guiding member 310 to always equal the radius of the rotating disc 320, so as to prevent the rotating disc 320 from moving away from the guiding member 310 during rotation, and thus ensure that the rotating disc 320 and the guiding member 310 are always in contact.

[0082] Alternatively, the auxiliary guiding structure 400 comprises a groove 420 and a rotating shaft 410. One of the groove 420 and the rotating shaft 410 is arranged on the rotating disc 320, and the other is arranged on the base frame 100. The rotating shaft 410 is arranged opposite to the groove 420, for example, the rotating shaft 410 can be at least partially located in the groove 420. Moreover, the rotating shaft 410 is slidingly arranged along the extension direction of the groove 420, so as to be limited by the groove 420, and thus enable the rotating disc 320 and the rotating frame 200 to move in the preset direction X. The cooperation between the groove 420 and the rotating shaft 410 can make the specific structure of the auxiliary guiding structure 400 simpler, and thus facilitate manufacturing and reduce cost.

[0083] Further, please continue to refer to Figure 2 The rotating shaft 410 is arranged at the center of the rotating disc 320, that is, the rotating shaft 410 is coaxially arranged on the rotating disc 320. For example, the rotating shaft 410 can be arranged to penetrate the rotating disc 320, or the rotating shaft 410 can be arranged on only one side of the rotating disc 320 facing the base frame 100, which is not limited in the present embodiment. The groove 420 is arranged on the base frame 100, for example, the groove 420 can penetrate or not penetrate the base frame 100 in the thickness direction of the base frame 100, which is not limited in the present embodiment. The groove 420 extends in the preset direction X, and when the rotating disc 320 rolls along the guiding member 310, the rotating shaft 410 rotates in the groove 420 or rolls along the groove wall of the groove 420. By arranging the groove 420 to extend in the preset direction X, the machining and manufacturing of the groove 420 are facilitated.

[0084] Alternatively, the rotating shaft 410 is arranged on the base frame 100, specifically on the side of the base frame 100 facing the rotating disc 320. The groove 420 is arranged on the rotating disc 320, and the shape of the groove 420 is an arc shape curved toward the center of the rotating disc 320. The rotating shaft 410 is slidingly arranged along the extension direction of the arc-shaped groove 420, so as to ensure that the rotating disc 320 and the rotating frame 200 can move in the preset direction X.

[0085] In summary, the above two arrangement modes of the groove 420 and the rotating shaft 410 can both achieve the purpose of avoiding the rotating shaft from moving in a direction away from the guiding member 310, and both have high reliability.

[0086] Optionally, the length of the groove 420 is configured such that, when the rotating frame 200 is in the second position, the rotating shaft 410 is in contact with a groove wall of the groove 420 in the preset direction X, so as to limit the movement limit of the rotating disc 320 and the rotating frame 200 in the rotating direction R1, and the groove wall of the groove 420 is used as a limiting structure, thereby improving the utilization rate of the groove 420, and the overall structure of the safety seat can be simplified without the need for additional limiting structures.

[0087] Similarly, the length of the groove 420 is also configured such that, when the rotating frame 200 is in the third position, the rotating shaft 410 is in contact with another groove wall of the groove 420 in the preset direction X, so as to limit the movement limit of the rotating disc 320 and the rotating frame 200 in the rotating direction R2.

[0088] In some optional embodiments, the rotating disc 320 is a gear disc, and the outer contour of the gear disc is circular as a whole. When the auxiliary guide structure 400 includes the rotating shaft 410, the rotating shaft 410 is coaxially arranged with the gear disc. The guide member 310 includes a gear rack 311 extending in the preset direction X. The gear disc is engaged with the gear rack 311. On the one hand, the gear rack 311 can guide the rotation of the gear disc. On the other hand, the cooperation between the gear rack 311 and the gear disc can improve the stability of the rotation and movement of the gear disc, so that the movement of the gear disc is smoother.

[0089] In addition, when the rotating frame 200 is in the first position, the second position or the third position, the gear rack 311 limits the gear disc in the preset direction X, that is, directly applying a force along the preset direction X to the rotating frame 200 cannot move the gear disc relative to the gear rack 311 in the preset direction X. Only when the rotating frame 200 is driven to rotate, the gear disc can move along the gear rack 311, so that the rotating frame 200 can be stably positioned at the first position, the second position or the third position, thereby reducing the probability of shaking of the rotating frame 200 and the seat, and improving the safety of the safety seat.

[0090] In some other optional embodiments, the rotating disc 320 is disc-shaped, and the outer circumferential surface of the rotating disc 320 is a smooth surface. The surface of the guide member 310 facing the rotating disc 320 is a plane. When the rotating disc 320 rolls along the guide member 310, the outer circumferential surface of the rotating disc 320 is in frictional contact with the surface of the guide member 310 facing the rotating disc 320, and the purpose of the rotating disc 320 rolling while rotating along the guide member 310 to move the center of the rotating disc 320 in the preset direction X can also be achieved.

[0091] Optionally, the safety seat further comprises an axial locking structure (not shown in the figure) for limiting the movement of the rotating frame 200 relative to the base frame 100 in the axial direction of the base frame 100, ensuring the smooth rotation and movement of the rotating frame 200 relative to the base frame 100 in the preset direction X.

[0092] For example, the locking structure is a locking block mounted on the rotating shaft 410 at one end of the groove 420, the length or width of the locking block is greater than the width of the groove 420, so that the locking block cannot pass through the groove 420, thereby achieving the limitation of the movement of the rotating frame 200 relative to the base frame 100 in the axial direction of the base frame 100. For another example, the locking structure comprises a dovetail groove and a dovetail block, one of the two is arranged on the rotating frame 200 and the other is arranged on the base frame 100, the dovetail groove is arc-shaped so as not to interfere with the rotation and translation of the rotating frame 200, and the dovetail block is in sliding fit with the dovetail groove to limit the movement of the rotating frame 200 relative to the base frame 100 in the axial direction of the base frame 100.

[0093] Optionally, as shown in Figure 9 the safety seat further comprises a base 500, and the base frame 100 is rotatably connected to the base 500. The base 500 is used for being mounted on the rear seat of the vehicle, and the connection between the base 500 and the rear seat is a fixed connection, and the base 500 cannot rotate or translate relative to the rear seat. By rotatably connecting the base frame 100 to the base 500, the base frame 100 can rotate 360° relative to the base 500 to adjust the orientation of the base frame 100, the rotating frame 200 and the seat.

[0094] For example, the central axis of the base frame 100 is parallel to or coincides with the central axis of the base 500, and the base frame 100 can rotate relative to the base 500 with the central axis of the base frame 100 or the central axis of the base 500 as the rotation axis.

[0095] In some optional embodiments, the centers of the guide 310 and the rotating disc 320 are located on both sides of the central axis of the base frame 100, i.e., the center of the rotating disc 320 does not coincide with the central axis of the base frame 100, and the groove 420 and the center of the rotating disc 320 are located on the same side of the central axis of the base frame 100.

[0096] Embodiment Two

[0097] The safety seat provided in the embodiment is different from that in Embodiment One in that the specific structure of the auxiliary guide structure is different.

[0098] Specifically, in the embodiment, the rotating disc is arranged on the rotating frame, and the guide and the auxiliary guide structure are arranged on the base frame.

[0099] The auxiliary guide structure and the guide are located on two sides of the rotating disc in a direction perpendicular to the preset direction, so that the rotating disc is located between the auxiliary guide structure and the guide.

[0100] The auxiliary guide abuts against the rotating disc to limit the rotating disc from moving away from the guide in a direction perpendicular to the preset direction. The rotating disc is in contact with the guide and the auxiliary guide structure, so that the guide and the auxiliary guide structure limit the rotating disc in a direction perpendicular to the preset direction, to avoid the rotating disc moving away from the guide, thereby ensuring that the rotating disc and the rotating frame can move in the preset direction, and improving the structural reliability.

[0101] Further, when the guide comprises a rack and the rotating disc is a toothed disc, the auxiliary guide structure is arranged to extend in a direction parallel to the rack, that is, the auxiliary guide structure extends in the preset direction. Moreover, the auxiliary guide structure abuts against the edge of the toothed disc. It should be noted that the auxiliary guide structure is only in contact with the toothed disc, but not engaged. If the auxiliary guide structure is also a toothed structure, the rotating disc, the auxiliary guide structure and the rack will be stuck and cannot move. For example, the surface of the auxiliary guide structure facing the rotating disc is a plane.

[0102] For example, the auxiliary guide structure can be a strip structure, and the strip structure is fixedly arranged on the base frame. The two ends of the strip structure do not exceed the edge of the base frame, so as to avoid increasing the overall volume of the safety seat due to the arrangement of the auxiliary guide structure.

[0103] The other structures in the embodiment have similar structures and similar beneficial effects to the corresponding structures in the first embodiment, and the embodiment is not limited in this regard.

[0104] Embodiment three

[0105] The safety seat provided in the embodiment is different from the safety seat in the first embodiment in that the specific structure of the auxiliary guide structure is different.

[0106] Specifically, in the embodiment, two groups of auxiliary guide structures are provided. One group of auxiliary guide structures is the auxiliary guide structure in the first embodiment, and the other group of auxiliary guide structures is the auxiliary guide structure in the second embodiment.

[0107] For example, one set of auxiliary guide structures includes a rotating shaft and a groove, one of which is arranged on the rotating disc and the other of which is arranged on the base. The rotating shaft is arranged opposite to the groove, for example, the rotating shaft can be at least partially located in the groove. And the rotating shaft is arranged to slide along the extension direction of the groove to achieve the limiting of the rotating shaft by the groove, so that the rotating disc and the rotating frame move in the preset direction. Another set of auxiliary guide structures is arranged in a direction perpendicular to the preset direction, and the auxiliary guide structures are arranged on both sides of the guide on the rotating disc, so that the rotating disc is located between the auxiliary guide structures and the guide. The auxiliary guide is in contact with the rotating disc to limit the rotating disc from moving away from the guide in a direction perpendicular to the preset direction.

[0108] By arranging two sets of auxiliary guide structures, the limiting effect and reliability of the moving direction of the rotating shaft and the rotating frame can be further improved to ensure that the rotating shaft and the rotating frame can move in the preset direction.

[0109] Other structures in the embodiment have similar structures and similar beneficial effects to the corresponding structures in Embodiment One, and this embodiment is not limited thereto.

[0110] Note that the above are only the preferred embodiments of the present application and the technical principles applied. Those skilled in the art will understand that the present application is not limited to the specific embodiments described herein, and those skilled in the art can make various obvious changes, readjustments and substitutions without departing from the scope of the present application. Therefore, although the present application has been described in more detail through the above embodiments, the present application is not limited to the above embodiments, and can include more other equivalent embodiments without departing from the concept of the present application, and the scope of the present application is determined by the scope of the appended claims.
