Description

Technical Field

[0001] This invention relates to the field of children's products, and more specifically to a child safety seat. Background Technology

[0002] Child safety seats are increasingly used as a safety tool for children traveling in cars. To accommodate children of different ages and heights, child safety seats typically need to be installed in either forward-facing or rear-facing positions. Current child safety seats generally consist of a seat body and an ISOFIX connector fixed to the bottom of the seat body. The seat body includes a base, a seat that can rotatably mount on the base, and a locking mechanism that locks the base and seat together. However, the ISOFIX connector can only extend in a fixed direction relative to the seat body. Therefore, users can only connect to the car seat via the ISOFIX connector in either forward-facing or rear-facing positions. This design necessitates multiple connection methods for the child safety seat, making its structure more complex and its operation inconvenient. Summary of the Invention

[0003] Purpose of the invention: In order to solve the problems existing in the prior art, the present invention provides a child safety seat with a simple structure that can be connected to the car seat via an ISOFIX connector in both forward and rear-facing use.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A child safety seat includes a seat body and a connector connected to the seat body for connection with a car seat. The child safety seat has a forward-facing use state and a rear-facing use state. The connector is movably disposed on the seat body and can extend forward or backward relative to the seat body to connect with the car seat. The relative movement between the seat body and the connector allows the child safety seat to be switched between the forward-facing use state and the rear-facing use state.

[0006] According to some embodiments of the present invention, the connector is rotatably connected to the seat body via a rotating shaft that extends obliquely in the vertical direction, and the rotating shaft is fixedly connected to the connector.

[0007] In some preferred and specific embodiments, in the forward-facing use state, the pivot extends downwards from front to back at an angle, and in the reverse-facing use state, the pivot extends upwards from front to back at an angle. The pivot, with its specific directional angled extension, allows the upper part of the seat back to tilt downwards when the seat body is rotated to the reverse-facing use state, facilitating seating for younger children; and when the seat body is rotated to the forward-facing use state, the seat back rests against the car seat, facilitating seating for older children.

[0008] Furthermore, the angle between the axis of rotation and the plane containing the upper surface of the connector is an obtuse angle, preferably in the range of 100°-110°.

[0009] Furthermore, a first connector capable of being connected to or detached from the connector is provided on the seat body and located behind the pivot, and a second connector capable of being connected to or detached from the connector is provided on the seat body and located in front of the pivot. When the connector is connected to the first connector, the safety seat is in the forward-facing use state; when the connector is connected to the second connector, the safety seat is in the reverse-facing use state; when the connector is detached from both the first and second connectors, the connector can move relative to the seat body.

[0010] In some preferred embodiments, the connector includes a connector body rotatably connected to the bottom of the seat body via the pivot, and a third connector fixedly disposed on the connector body for connection or separation from the first or second connector, the third connector extending obliquely in the vertical direction. The connector body remains horizontally extended for easy connection to the ISOFIX interface of the car seat, regardless of whether the child seat is in a forward-facing or rear-facing position.

[0011] In some embodiments, the first connector and the second connector are respectively a first link and a second link extending in the left-right direction along the seat body, simplifying the structure of the car seat. Furthermore, the third connector has a through hole for insertion or separation from the first link or the second link.

[0012] In some preferred and specific embodiments, the third connector, in the forward use position, extends downward at an angle from front to back.

[0013] According to some embodiments of the present invention, the safety seat further includes a locking mechanism for locking the safety seat in a forward-facing or rear-facing state. The locking mechanism includes a locking member movably disposed on one of the two components, the seat body and the connector, and a first locking groove and a second locking groove disposed on the other component, located on opposite sides of the pivot and respectively engaging or disengaging with the locking member. When the locking member engages with either the first or the second locking groove, the locking mechanism locks the safety seat in a forward-facing or rear-facing state; when the locking member disengages from both the first and the second locking grooves, the locking mechanism unlocks.

[0014] In some preferred and specific embodiments, the connector includes a connector body rotatably connected to the bottom of the seat body via a pivot and a third connector fixedly disposed on the connector body. The locking member is slidably connected to the third connector. The locking mechanism further includes an elastic member disposed between the locking member and the connector body for causing the locking member to tend to insert into the first locking groove or the second locking groove. The locking member has an operating part for operating the locking member to cause the locking member to tend to separate from both the first locking groove and the second locking groove.

[0015] Furthermore, the first locking slot and the second locking slot are respectively formed on the seat body, and the first locking slot is located behind the second locking slot. When the locking member is inserted into the first locking slot, the locking mechanism locks the safety seat in the forward-facing use state; when the locking member is inserted into the second locking slot, the locking mechanism locks the safety seat in the reverse-facing use state.

[0016] In this invention, the third connecting member that is connected or separated from the first connecting member or the second connecting member and is slidably connected to the locking member can be the same component or two different components.

[0017] According to some embodiments of the present invention, the connectors are symmetrically arranged on the left and right sides of the seat body. Each connector includes a connector body rotatably connected to the bottom of the seat body and a third connector fixedly disposed on the connector body. The connector body includes a connecting frame rotatably connected to the bottom of the seat body and a connector slidably connected to the connecting frame in the front-rear direction of the seat body for connecting to the car seat. The connector can extend from one end of the connecting frame and connect to the car seat, and the length of the connector extending out of the connecting frame is adjustable. The third connector is fixedly disposed on the connecting frame and can also be connected to or separated from the front or rear of the seat body.

[0018] Furthermore, the connector has an opening for connecting to the ISOFIX interface on the car seat, and when the child safety seat is in a forward-facing or rear-facing position, the opening faces the opposite direction to the forward direction of the vehicle.

[0019] Furthermore, the connector is also provided with a movable locking hook portion inside the opening for cooperating with the car seat, the movable locking hook portion being able to retract or extend relative to the upper sidewall of the opening.

[0020] Furthermore, the connector extends forward or backward relative to the seat body to connect with the car seat. When the child safety seat is in forward-facing use, the connector extends backward relative to the seat body to connect with the car seat; when the child safety seat is in rear-facing use, the connector extends forward relative to the seat body to connect with the car seat.

[0021] According to some embodiments of the present invention, when the child safety seat is in a forward-facing position, the connector extends rearward relative to the seat body and connects to the vehicle seat; when the child safety seat is in a rear-facing position, the connector extends forward relative to the seat body and connects to the vehicle seat.

[0022] Furthermore, the lower surface of the seat body has a first support surface extending horizontally when the child safety seat is in the forward-facing use state, and the child safety seat is in a sitting position when it is in the forward-facing use state; the rear surface of the seat body has a second support surface extending horizontally when the child safety seat is in the rear-facing use state, and the child safety seat is in a reclining position when it is in the rear-facing use state.

[0023] Preferably, the angle formed between the plane containing the first support surface and the plane containing the second support surface is an acute angle; more preferably, the acute angle formed between the plane containing the first support surface and the plane containing the second support surface is 5° to 60°.

[0024] And / or, in the reverse use state, the angle formed between the plane containing the first support surface and the horizontal plane is an acute angle, and more preferably, in the reverse use state, the acute angle formed between the plane containing the first support surface and the horizontal plane is 25° to 35°.

[0025] According to some embodiments of the present invention, the seat body is a one-piece structure.

[0026] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0027] The child safety seat of the present invention can be switched between forward-facing and rear-facing use simply by rotating the connector relative to the seat body and then installing it in either direction. This is convenient to operate. Compared with traditional safety seats, the present invention can be connected to the car seat using the connector in both forward-facing and rear-facing use states, which also simplifies the structure of the seat body, making the child safety seat simpler in structure and easier to manufacture.

[0051] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0052] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," "left-right direction," "height direction," and "front-back direction," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 The orientation or positional relationship shown when a child is seated in a child safety seat is for the purpose of facilitating and simplifying the description of the invention, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, only have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0053] It should be noted that, unless otherwise specified, when a feature is referred to as "fixed" or "connected" to another feature, it can be directly fixed or connected to the other feature, or indirectly fixed or connected to the other feature. Unless otherwise explicitly specified and limited, the terms "installed," "connected," and "attached" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0054] See Figures 1-19 The child safety seat includes a seat body 100 and a connector 200 rotatably connected to the bottom of the seat body 100 via a pivot 1 extending obliquely in the vertical direction and used for connecting to a car seat. The connector 200 can also extend forward or backward relative to the seat body 100 to connect to the car seat. In this invention, "forward" refers to the direction the child faces when riding in the child safety seat, and "backward" refers to the direction the child faces away from when riding in the child safety seat. The safety seat has a forward-facing usage state and a rear-facing usage state, and the relative rotation between the seat body 100 and the connector 200 allows for tangential movement between these two states. In the reverse installation, in the forward-facing use state of the present invention, the direction in which the child sitting in the child safety seat faces is the same as the forward direction of the car's travel. In the rear-facing use state, the direction in which the child sitting in the child safety seat faces is opposite to the forward direction of the car's travel. When the child safety seat is in the forward-facing use state, the connector 200 extends rearward relative to the seat body 100 to connect with the car seat. When the safety seat is in the rear-facing use state, the connector 200 extends forward relative to the seat body 100 to connect with the car seat. In order to better connect with the car seat, the connector 200 extends horizontally in both the forward-facing and rear-facing use states.

[0055] The lower surface of the seat body 100 has a first support surface M extending horizontally when the child safety seat is in the forward-facing position, and the child safety seat is in a sitting position when in the forward-facing position. The rear surface of the seat body 100 has a second support surface N extending horizontally when the child safety seat is in the rear-facing position, and the child safety seat is in a reclining position when in the rear-facing position. In the sitting position of this invention, the angle α between the plane against which the rear surface of the seat body 1 rests and the horizontal plane (see...) Figure 10 The angle β between the plane against which the rear surface of the seat body 1 rests (this surface is a virtual plane in the reclining position) and the horizontal plane (see [reference]). Figure 17 The value is larger. The plane on which the rear surface of the seat body 1 rests in the sitting and reclining positions refers to the plane containing the cross-section at the same position on the rear surface of the seat body 1. However, in the sitting position, the plane on which the rear surface of the seat body 1 rests is the plane containing the front surface of the car seat.

[0056] See Figure 17 The angle γ formed between the plane containing the first support surface M and the plane containing the second support surface N is an acute angle, ranging from 5° to 60°. In the reverse use state, since the second support surface N is on a horizontal plane, the angle formed between the plane containing the first support surface M and the horizontal plane is also an acute angle γ. Preferably, the angle γ formed between the plane containing the first support surface M and the horizontal plane ranges from 25° to 35°. Compared with the arrangement where the first support surface M extends horizontally in both the forward and reverse use states, the child safety seat in this embodiment is provided with a first support surface M and a second support surface N so that the child can recline at a greater angle and have a more comfortable lying posture in the reverse use state. Correspondingly, in order to match the lying posture in the reverse use state, in the forward use state, the rotating shaft 1 extends downward from front to back at an angle, and in the reverse use state, the rotating shaft 1 extends upward from front to back at an angle. The rotating shaft 1 is fixedly connected to the connector 200, and the angle δ formed between the axis of the rotating shaft 1 and the plane containing the upper surface of the connector 200 is (see...). Figure 20 The included angle δ is an obtuse angle. Preferably, the included angle δ is in the range of 100-110°. More preferably, in this embodiment, the included angle δ between the center line of the rotating shaft 1 and the upper surface of the connector 200 is 105°.

[0057] A first connector that can be connected to or separated from the connector 200 is provided on the seat body 100 and located behind the pivot 1. A second connector that can be connected to or separated from the connector 200 is provided on the seat body 100 and located in front of the pivot 1. In order to simplify the structure of the child safety seat, the first connector and the second connector are respectively a first link 5 and a second link 6 that extend along the left and right directions of the seat body 100.

[0058] In this example, the connector 200 is symmetrically arranged on the left and right sides of the seat body 100, and correspondingly, the first link 5 and the second link 6 are respectively arranged on the left and right sides of the seat body 100.

[0059] See Figure 18-19 Each connector 200 includes a connector body and a third connector 10 fixedly mounted on the connector body. The connector body includes a connecting frame 8 rotatably connected to the bottom of the seat body 100 via a pivot 1, and a connector 9 slidably connected to the connecting frame 8 along the front-rear direction of the seat body 100 for connecting to the car seat. The connector 9 can extend from one end of the connecting frame 8 and connect to the car seat, and the length of the connector 9 extending from the connecting frame 8 is adjustable. The connector 9 has an opening 17 for connecting to the ISOFIX interface on the car seat. A movable locking hook 18 for cooperating with the car seat is also provided in the opening 17. The movable locking hook 18 can be retracted or extended relative to the upper side wall of the opening 17. The movable locking hook 18 also has an opening. The third connector 10 is fixedly mounted on the connecting frame 8. In this example, in order to ensure smooth connection between the third connector 10 and the seat body 100 in the forward-facing use state, the third connector 10 is configured to extend downwards from front to back in the forward-facing use state.

[0060] The two connectors 200 are connected to or disconnected from both ends of the first link 5 or the second link 6, respectively. When the two connectors 200 are connected to both ends of the first link 5, the child safety seat is in a forward-facing position; when the two connectors 200 are connected to both ends of the second link 6, the child safety seat is in a rear-facing position; when the two connectors 200 are disconnected from both the first link 5 and the second link 6, the two connectors 200 can rotate relative to the seat body 100. Specifically, the connector 200 is provided with through holes 7 that can be inserted into or separated from the first link 5 or the second link 6. The through holes 7 are respectively opened on the third connector 10. When the first link 5 or the second link 6 is inserted into the through hole 7, the connector 200 is connected to the first link 5 or the second link 6; when both the first link 5 and the second link 6 are disconnected from the through hole 7, both the first link 5 and the second link 6 are disconnected from the connector 200, and the connector 200 can rotate relative to the seat body 100.

[0061] At the bottom of the seat body 100, corresponding to the two ends of the first connecting rod 5 and the two ends of the second connecting rod 6, a first clearance groove 13 and a second clearance groove 14 are respectively provided to avoid the third connecting member 10. When the first connecting rod 5 or the second connecting rod 6 is inserted into the through hole 7 on the third connecting member 10, the third connecting member 10 is located in the first clearance groove 13 or the second clearance groove 14.

[0062] In this example, the existing connection relationship between the connector 9 and the connecting frame 8 can be used, which is not the key point. It is only necessary to ensure that the connector 9 can extend out of the connecting frame 8 from one end of the connecting frame 8 and that the extension length is adjustable and can be stored inside the connecting frame 8.

[0063] The child safety seat also includes a locking mechanism for locking the child safety seat in a forward-facing and rear-facing position. The locking mechanism is disposed between the seat body 100 and the connector 200, and the locking mechanism is disposed between the connector 200 on both sides and the seat body 100.

[0064] Each locking mechanism includes a locking member 2 slidably mounted on the connector 200 and a first locking groove 3 and a second locking groove 4 located at the bottom of the seat body 100 and on the front and rear sides of the pivot 1, which are engaged with or disengaged from the locking member 2. The first locking groove 3 is located behind the second locking groove 4. When the locking member 2 is engaged with the first locking groove 3, the locking mechanism locks the safety seat in the forward-facing position. When the locking member 2 is engaged with the second locking groove 4, the locking mechanism locks the safety seat in the rear-facing position. When the locking member 2 is disengaged from both the first locking groove 3 and the second locking groove 4, the locking mechanism unlocks.

[0065] The locking member 2 is slidably disposed on the third connecting member 10. The locking mechanism also includes an elastic member 11, a spring, disposed between the locking member 2 and the connecting bracket 8, for causing the locking member 2 to tend to engage with the first locking groove 3 or the second locking groove 4. The locking member 2 has an operating part 2b for operating the locking member 2 to tend to separate it from both the first locking groove 3 and the second locking groove 4. See details... Figure 20 The locking member 2 includes a sliding part 2a slidably disposed on the third connector 10 and an operating part 2b fixedly disposed on the sliding part 2a. Specifically, the sliding part 2a is slidably disposed inside the third connector 10 and one end of the sliding part 2a protrudes from the third connector 10 and is inserted into or separated from the first locking groove 3 or the second locking groove 4. A sliding groove 12 is opened on the third connector 10 at the position corresponding to the position of the operating part 2b along the sliding direction of the sliding part 2a, and the operating part 2a is slidably disposed in the sliding groove 12.

[0066] See Figure 20The first locking groove 3 is opened on the upper groove wall of the first clearance groove 13, and the second locking groove 4 is opened on the upper groove wall of the second clearance groove 14. The sliding part 2a of the locking member 2 is opened with a through groove corresponding to the through hole 7 of the third connecting member 10. When the first connecting rod 5 or the second connecting rod 6 is inserted into the through hole 7, the first connecting rod 5 or the second connecting rod 6 is also inserted into the through groove and can slide relative to the through groove.

[0067] In this example, the third connector 10 is connected to or separated from the seat body 100, and the locking member 2 and the elastic member 11 are respectively disposed in the third connector 10, which greatly simplifies the structure of the safety seat.

[0068] See Figure 19 The rotating shaft 1 extends obliquely in the vertical direction, and its lower end is fixedly connected to the connecting frame 8. A socket is provided at the bottom of the seat body 100 corresponding to the position of the rotating shaft 1. The rotating shaft 1 is inserted into the socket and rotates within it. A limiting member 16 is also provided at the upper end of the rotating shaft 1 to prevent it from sliding out of the socket and thus preventing the connector 200 from disengaging from the seat body 100. A third clearance groove 15 is provided at the bottom of the seat body 100 corresponding to the position of the connecting frame 8 of the connector 200 to allow the connecting frame 8 to rotate. The connector 200 rotates 180° around the axis of the rotating shaft 1.

[0069] The connection between the connecting frame 8 and the rotating shaft 1 is divided into a first section and a second section. The second section is longer than the first section. The third connector 10 is fixed on the second section. The third clearance groove 15 is used to avoid the first section. When the safety seat is in the forward or reverse use state, the upper surface of the first section abuts against the upper groove wall of the third clearance groove 15 to further support and stabilize the connector 200. The angle between the axis of the rotating shaft 1 and the plane containing the upper surface of the second section is 100°-110°.

[0070] How does this child safety seat work?

[0071] See Figures 1-10 When the child safety seat is in the forward-facing position, the connector 200's connecting bracket 8 extends horizontally, and the first support surface M of the seat body 100 extends horizontally as a support. The third connector 10 is connected to the first link 5, and the end of the first link 5 is inserted into the through hole 7 of the third connector 10. The third connector 10 is located in the first clearance groove 13, and the locking member 2 is inserted into the first locking groove 3. The locking mechanism locks the safety seat in the forward-facing position. At this time, the connector 200's connector 9 slides backward relative to the seat body 100 out of the connecting bracket 8 and connects to the car seat's ISOFIX interface through the movable locking hook part 18. The opening 17 on the connector 9 faces the rear of the child safety seat, and the opening of the movable locking hook part 18 is set downward.

[0072] When the child safety seat needs to be used rear-facing, the connector 200 separates from the car seat. Then, the operating part 2b of the locking member 2 is operated, causing the sliding part 2a to slide downwards and compress the elastic member 11, thereby disengaging the sliding part 2a from the first locking groove 3. Figure 7 As shown, the locking mechanism unlocks, releasing the operating part 2b, and the sliding part 2a slides upward and resets under the action of the elastic member 11. Then, the third connecting member 10 of the connector 200 separates from the first connecting rod 5, and the connector 200 is rotated around the rotating shaft 1. See [reference needed]. Figures 11-14 Rotate the third connector 10 to connect with the second link 6. Operate the operating part 2b to make the sliding part 2a slide downward and continue to rotate the connector 200. When the connector 200 has rotated 180°, release the operating part 2b. Under the action of the elastic member 11, the sliding part 2a is inserted into the second locking groove 4, the locking mechanism locks, and the connector 200 is fixed relative to the seat body 100.

[0073] Then, the seat body 100 is installed backwards on the car seat, so that the second support surface N of the seat body 100 extends horizontally as a support, the connecting bracket 8 of the connector 200 extends horizontally, and the connector 9 of the connector 200 slides out of the connecting bracket 8 and connects to the ISOFIX interface of the car seat. See [link to documentation]. Figures 15-17 At this time, the connector 9 of connector 200 slides forward relative to the seat body 1, extending the connecting bracket 8 to connect with the ISOFIX interface of the car seat. The opening 17 of connector 9 faces the front of the child safety seat, and the opening of the movable locking hook 18 remains downward. Whether the safety seat is in forward-facing or rear-facing mode, the opening 17 of connector 9 is always opposite to the forward-moving direction of the vehicle, and the opening of the movable locking hook 18 is always downward, facilitating engagement with the ISOFIX interface of the car seat.

[0074] When the child safety seat needs to be reversed, simply rotate the connector 200 relative to the seat body 100 and then install it in the forward or reverse direction. The operation is convenient and greatly simplifies the structure of the seat body 100 compared to traditional safety seats, making the child safety seat structure simpler and easier to manufacture.

[0075] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
