A child safety seat

Abstract

This invention discloses a child safety seat with forward-facing and rear-facing usage states. The child safety seat includes a base, a seat body rotatably mounted on the base, and a status indicator rotatably or slidably mounted on the base. The status indicator has at least a first indicator and a second indicator. An indicator window is provided on the base. Movement of the status indicator relative to the base aligns one of the first and second indicator information with the indicator window. When the child safety seat is in forward-facing or rear-facing usage states, the first indicator is aligned with the indicator window; when the child safety seat deviates from the forward-facing or rear-facing usage state, the second indicator is aligned with the indicator window. During the reversal of the child safety seat, the information indicated by the status indicator can determine whether the child safety seat is in a forward-facing or rear-facing usage state. This avoids problems such as the seat body not being rotated into position, resulting in an insecure installation, and improves the safety of the child safety seat.

Description

Technical Field

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

[0002] Child safety seats are generally used when children are riding in cars to improve their safety. A child safety seat typically consists of a base and a seat body mounted on the base. The seat body can rotate relative to the base, allowing the child safety seat to be used in both forward-facing and rear-facing positions, and can be switched between these positions, making it suitable for children of different ages.

[0003] In existing technology, when the seat body rotates relative to the base to switch between forward-facing and rear-facing positions, it's impossible to indicate whether the seat body has rotated to the correct position. If the seat body doesn't rotate to the correct position, it will be insecurely installed. This results in greater vibration during vehicle movement, affecting the comfort of the child safety seat and potentially causing accidents and endangering the child, rendering the child safety seat ineffective in protecting the child's safety while traveling. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by providing a child safety seat that can remind the user whether the child safety seat is in a forward-facing or rear-facing position.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A child safety seat has a forward-facing and a rear-facing usage state. The child safety seat includes a base and a seat body rotatably mounted on the base. The seat body rotates relative to the base to switch between the forward-facing and rear-facing usage states. The child safety seat also includes a status indicator rotatably or slidably mounted on the base. The status indicator has at least a first indicator and a second indicator. An indicator window is provided on the base. The status indicator can rotate or slide relative to the base so that one of the first and second indicator information is aligned with the indicator window. When the child safety seat is in the forward-facing or rear-facing usage state, the first indicator is aligned with the indicator window. When the child safety seat deviates from the forward-facing or rear-facing usage state, the second indicator is aligned with the indicator window.

[0007] Preferably, the child safety seat further includes a drive assembly for actuating the status indicator to align the first indicator information with the indicator window. The drive assembly includes a traction cable with one end disposed on the status indicator, a first drive member and a second drive member for pulling the traction cable to actuate the status indicator, and a third drive member for actuating the first drive member and the second drive member to pull the traction cable. The first drive member is rotatably or slidably disposed at the rear of the base, the second drive member is rotatably or slidably disposed at the front of the base, and the third drive member is rotatably and / or slidably disposed on the seat body. When the child safety seat is in a forward-facing position, the third drive member can abut against the first drive member. When the child safety seat is in a rear-facing position, the third drive member can abut against the second drive member.

[0008] Furthermore, the drive assembly also includes a connector movably disposed on the base, the rear end of the connector being connected to the first drive member, the front end of the connector being connected to the second drive member, one end of the traction cable being disposed on the status indicator, and the other end of the traction cable being disposed on one of the first drive member and the second drive member.

[0009] In one specific embodiment, the connector is a rigid connector.

[0010] Preferably, both the first driving member and the second driving member are rotatably mounted on the base, the rear end of the connector is rotatably connected to the first driving member, and the front end of the connector is rotatably connected to the second driving member.

[0011] In another specific embodiment, the connector is a flexible connector, and the two ends of the connector are respectively fixedly disposed on the first driving member and the second driving member.

[0012] Furthermore, the traction cable includes a first traction cable and a second traction cable. One end of the first traction cable is disposed on the status indicator, and the other end of the first traction cable is disposed on the first drive member. One end of the second traction cable is disposed on the status indicator, and the other end of the second traction cable is disposed on the second drive member.

[0013] Furthermore, the base has a first clearance groove at its rear and a second clearance groove at its front. The first drive member is located at the first clearance groove, and the second drive member is located at the second clearance groove. When the child safety seat is in forward-facing use, the third drive member extends out of the seat body and into the first clearance groove to abut against the first drive member. When the child safety seat is in rear-facing use, the third drive member extends out of the seat body and into the second clearance groove to abut against the second drive member.

[0014] Furthermore, the drive assembly also includes a first elastic member for providing elastic force so that the third drive member can abut against and cooperate with the first drive member and the second drive member, with the two ends of the first elastic member respectively disposed on the third drive member and the seat body.

[0015] Furthermore, the child safety seat also includes a second elastic member for providing elastic force to align the second indication information with the indication window, with the two ends of the second elastic member respectively disposed on the status indicator and the base.

[0016] Furthermore, the drive assembly also includes a first elastic element for providing an elastic force to enable the third drive element to engage with the first drive element and the second drive element, wherein the elastic force of the first elastic element is greater than the elastic force of the second elastic element.

[0017] Preferably, the first indication information is displayed in green, and the second indication information is displayed in red.

[0018] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art: When the child safety seat of the present invention rotates relative to the base to change the direction of the child safety seat, the information indicated by the status indicator can be used to determine whether the child safety seat is in a forward or reverse use state. This can avoid the problem of the seat body not rotating into place and the seat body not being installed securely, thereby improving the safety of the child safety seat during use.

[0027] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] In the following description, the directions "front," "rear," "left," "right," "up," and "down" all refer to the installation of a child safety seat in a car seat, with the front of the car being "front," the rear being "rear," and the left and right sides being "left" and "right," respectively. Figure 4 In the figure, the left direction is "front", the right direction is "back", the top direction is "up", and the bottom direction is "down". The directions perpendicular to the paper are "left" and "right". The above definitions of directions are only for the convenience of describing the present invention and simplifying the description, 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, and therefore should not be construed as limiting the present invention.

[0029] like Figure 1 , Figures 5-7 As shown, the child safety seat of the present invention includes a base 1 and a seat body 2 disposed on the base 1.

[0030] The seat body 2 is rotatably mounted on the base 1 via a pivot extending vertically. This child safety seat has a forward-facing and a rear-facing configuration. When the child safety seat is in the forward-facing position, the child's face is forward while seated in the seat. Figure 4As shown. When the child safety seat is in the rear-facing position, the child's face is facing backwards while seated in the seat, as... Figure 5 As shown. The seat body 2 can rotate relative to the base 1 around the pivot, allowing the child safety seat to switch between forward-facing and rear-facing positions.

[0031] In this embodiment, as Figure 5 and Figure 6 As shown, the seat body 2 includes a seat shell 21 and a connecting seat 22. The connecting seat 22 is rotatably mounted on the base 1 about a pivot, and the seat shell 21 is mounted on the connecting seat 22. When the connecting seat 22 rotates relative to the base 1 about the pivot, it causes the seat shell 21 to rotate synchronously relative to the base 1 about the pivot. Preferably, the seat shell 21 can slide on the connecting seat 22 in the front-to-back direction, which allows adjustment of the child safety seat's posture and improves comfort during use.

[0032] The child safety seat also includes a status indicator 3, which is rotatably or slidably mounted on the base 1. When the child safety seat is switched between forward-facing and rear-facing modes, the status indicator 3 can remind the user whether the child safety seat is in the forward-facing or rear-facing mode. In this embodiment, a fixing seat 11 is fixedly mounted on the base 1, and the status indicator 3 is rotatably mounted on the fixing seat 11.

[0033] Specifically, the status indicator 3 has at least first indicator information and second indicator information, and the base 1 is provided with an indicator window 12, such as... Figure 1 and Figure 3 As shown. When the status indicator 3 rotates or slides relative to the base 1, it can align either the first indicator information or the second indicator information with the indicator window 12. When the child safety seat is in the forward-facing or rear-facing position, the first indicator information is aligned with the indicator window 12. When the child safety seat deviates from the forward-facing or rear-facing position, the second indicator information is aligned with the indicator window 12. In this way, the user can clearly and accurately determine whether the seat body 2 of the child safety seat has rotated into position relative to the base 1 based on the information displayed in the indicator window 12, thereby improving the safety performance of the child safety seat during use.

[0034] In this embodiment, the first indicator information is displayed in green, and the second indicator information is displayed in red. That is, when the child safety seat is in the forward-facing or rear-facing position, the user will see green in the indicator window 12. When the child safety seat deviates from the forward-facing or rear-facing position, the user will see red in the indicator window 12.

[0035] The preferred status indicator 3 and the indicator window 12 are respectively set on the left and right sides of the base 1, so that the user can easily check the status of the status indicator 3.

[0036] The child safety seat also includes a drive assembly that can drive the status indicator 3 to rotate or slide relative to the base 1, thereby aligning the first indication information with the indication window 12, even if the indication window 12 displays green.

[0037] like Figure 2 , Figures 5-7 As shown, the drive assembly includes a traction cable 41, a first drive member 42, a second drive member 43, and a third drive member 44.

[0038] One end of the traction cable 41 is disposed on the status indicator 3. The traction cable 41 is used to pull the status indicator 3, causing it to rotate or slide relative to the base 1, thereby aligning the first indicator information with the indicator window 12. In this embodiment, the traction cable 41 is disposed on the left and right sides respectively corresponding to the status indicator 3, and one end of the traction cable 41 on each side is disposed on the status indicator 3 on the corresponding side.

[0039] The first drive member 42 is rotatably or slidably disposed at the rear of the base 1, and the second drive member 43 is rotatably or slidably disposed at the front of the base 1. When the first drive member 42 and the second drive member 43 are in motion, they can pull the traction cable 41, thereby pulling the status indicator 3 to move.

[0040] The third drive member 44 is rotatably and / or slidably mounted on the seat body 2. When the child safety seat is in forward-facing use, the third drive member 44 extends out of the seat body 2 and engages with the first drive member 42, thereby pulling the status indicator 3 via the traction cable 41 to align its first indicator information with the indicator window 12. When the child safety seat is in rear-facing use, the third drive member 44 extends out of the seat body 2 and engages with the second drive member 43, thereby pulling the status indicator 3 via the traction cable 41 to align its first indicator information with the indicator window 12.

[0041] like Figure 5 and Figure 6 As shown, the drive assembly also includes a first elastic element 45, which provides an elastic force to the third drive element 44 so that the third drive element 44 can partially extend outside the seat body 2, thereby enabling it to engage with the first drive element 42 or the second drive element 43. Specifically, the first elastic element 45 is a spring, and its two ends are respectively disposed on the third drive element 44 and the seat body 2.

[0042] In this embodiment, as Figures 5-7As shown, a first clearance groove 13 is provided at the rear of the base 1, and a second clearance groove 14 is provided at the front of the base 1. A first driving member 42 is rotatably disposed at the position of the first clearance groove 13, and a second driving member 43 is rotatably disposed at the position of the second clearance groove 14. A third driving member 44 is rotatably disposed on the connecting seat 22.

[0043] This embodiment provides several ways to pull the traction cable 41 by the action of the first driving member 42 and the second driving member 43, as follows.

[0044] Implementation Method 1:

[0045] like Figure 2 As shown, the drive assembly also includes a connector 46, which is movably mounted on the base 1. The connector 46 extends in the front-rear direction, with its rear end connected to the first drive member 42 and its front end connected to the second drive member 43. One end of the traction cable 41 is mounted on the status indicator 3, and the other end of the traction cable 41 is mounted on either the first drive member 42 or the second drive member 43.

[0046] Thus, when one of the first driving member 42 and the second driving member 43 is engaged with the third driving member 44, the action of the first driving member 42 and the second driving member 43 directly pulls the status indicator 3 via the traction cable 41, aligning the first indication information with the indicator window 12. When the other of the first driving member 42 and the second driving member 43 is engaged with the third driving member 44, the action of the other of the first driving member 42 and the second driving member 43 drives the action of the first driving member 42 and the second driving member 43 via the connecting member 46, which in turn pulls the status indicator 3 via the traction cable 41, aligning the first indication information with the indicator window 12.

[0047] When the indicator window 12 is located at the front of the base 1, the other end of the traction cable 41 is mounted on the second drive member 43. When the indicator window 12 is located at the rear of the base 1, the other end of the traction cable 41 is mounted on the first drive member 42. This allows the traction cable 41 to be shorter, reducing frictional loss when pulling the traction cable 41, and making it easier to pull the status indicator 3 via the traction cable 41.

[0048] In this embodiment, the indicator window 12 is located at the front of the base 1, and the other end of the traction cable 41 is disposed on the second drive member 43.

[0049] The connector 46 can be a rigid connector, in which case the rear end of the connector 46 is rotatably connected to the first drive member 42, and the front end of the connector 46 is rotatably connected to the second drive member 43.

[0050] Of course, the connector 46 can also be a flexible connector. In this case, the rear end of the connector 46 is fixedly mounted on the first drive member 42, and the front end of the connector 46 is fixedly mounted on the second drive member 43. When the connector 46 is a flexible connector, a third elastic member is also required to allow the components of the first drive member 42 and the second drive member 43 that are not connected to the traction cable 41 to rotate in the opposite direction and reset.

[0051] Implementation Method Two:

[0052] (Not shown in the diagram) The traction cable 41 includes a first traction cable and a second traction cable. One end of the first traction cable is attached to the status indicator 3, and the other end is attached to the first drive member 42. One end of the second traction cable is attached to the status indicator 3, and the other end is attached to the second drive member 43.

[0053] Thus, when the third driving member 44 abuts against the first driving member 42, it drives the first driving member 42 to move, which in turn pulls the status indicator 3 via the first traction cable, aligning the first indicator information with the indicator window 12. When the third driving member 44 abuts against the second driving member 43, it drives the second driving member 43 to move, which in turn pulls the status indicator 3 via the second traction cable, aligning the first indicator information with the indicator window 12.

[0054] like Figure 2 As shown, the child safety seat also includes a second elastic element 5, which provides an elastic force to the status indicator 3 so that the status indicator 3 can rotate to align the second indicator information with the indicator window 12. In this embodiment, the second elastic element 5 is a torsion spring, with its two ends respectively disposed on the status indicator 3 and the fixing base 11.

[0055] When the child safety seat is in forward-facing use, the position of the third drive member 44 corresponds to the position of the first clearance groove 13. The elastic force of the first elastic member 45 is greater than the sum of the elastic forces of the second elastic member 5 and the third elastic member. Under the action of the elastic force of the first elastic member 45, the third drive member 44 partially extends out of the seat body 2 and into the first clearance groove 13, thereby abutting against the first drive member 42, causing the first drive member 42 to rotate to the first position. When the first drive member 42 rotates, it pulls the connecting member 46 to move relative to the base 1, thereby driving the second drive member 43 to rotate relative to the base 1 to the second position. When the second drive member 43 rotates, it pulls the traction cable 41, causing the traction cable 41 to pull the status indicator 3 to rotate so that the first indicator information is aligned with the indicator window 12. Figure 5 As shown.

[0056] When the child safety seat is in rear-facing mode, the position of the third drive member 44 corresponds to the position of the second clearance groove 14. Under the elastic force of the first elastic member 45, the third drive member 44 partially extends out of the seat body 2 and into the second clearance groove 14, thus engaging with the second drive member 43. This causes the second drive member 43 to rotate to the second position. When the second drive member 43 rotates, it pulls the traction cable 41, causing the traction cable 41 pull status indicator 3 to rotate so that the first indicator information is aligned with the indicator window 12. During the process of the second drive member 43 rotating to the second position, the first drive member 42 is pulled to the first position via the connecting member 46. Figure 6 As shown.

[0057] When the child safety seat shifts between forward-facing and rear-facing positions, the third drive member 44 is misaligned with both the first and second clearance slots 13 and 14. Due to the abutment of the base 1, the third drive member 44 retracts completely into the seat body 2 after overcoming the elastic force of the first elastic member 45. This disengages the third drive member 44 from the first drive member 42 and the second drive member 43, thus eliminating the force exerted by the third drive member 44 on the first and second drive members 42. Consequently, the force exerted by the traction cable 41 on the status indicator 3 also disappears. The status indicator 3 then rotates in the opposite direction under the elastic force of the second elastic member 5, aligning the second indicator information with the indicator window 12. At this time, the second drive member 43 can be pulled back to the third position via the traction cable 41 under the elastic force of the second elastic member 5. Conversely, the second drive member 43, when rotating in the opposite direction, pulls the first drive member 42 back to the fourth position via the connecting member 46. Figure 7 As shown.

[0058] 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.
