Description

Technical Field

[0001] This application relates to a child safety seat, which includes an anti-misuse mechanism. Background Technology

[0002] Child safety seats are a common device that is fixed in vehicles such as cars to provide a safe riding environment for children.

[0003] In some cases, child safety seats are designed to rotate 360 ​​degrees around a vertical axis, meaning the seat can rotate between a forward-facing position (seat facing the direction of travel) and a rear-facing position (seat facing away from the direction of travel). For safety, children under 15 months should generally use a rear-facing child safety seat. To prevent users from mistakenly placing children under 15 months in a forward-facing child safety seat, the seat is equipped with a rotation-correction mechanism to prevent misuse.

[0004] In child safety seats equipped with anti-misuse mechanisms, users can switch the seat to an unlocked mode that allows rotation to a forward-facing position or a locked mode that prevents rotation to a forward-facing position via the mechanism's operating mechanism. However, existing anti-misuse mechanisms lack an automatic push-positioning mechanism. The operator may not fully engage the mechanism, resulting in the seat mode not actually being switched, ultimately leading to misuse of the seat's orientation and posing a safety hazard to children during travel.

[0005] A turntable is typically provided between the seat and the base to allow the seat to rotate between forward and rearward positions. In some cases, it may be desirable for the seat to be detachable from the turntable for seat replacement or relocation to other usage environments.

[0006] Therefore, there is a need for a mechanism to prevent misuse of child safety seats, whose operating components can be automatically pushed into position and allow the seat to be separated from the turntable. Summary of the Invention

[0015] In one embodiment, the anti-misuse mechanism further includes a linkage that swings about a lateral axis, the operating member abuts against one end of the linkage, and the lateral movement of the operating member causes the linkage to swing.

[0016] In one embodiment, the actuating member includes a beveled portion, the upper surface of which extends obliquely in a transverse manner, being higher at one end and lower at the other; the linkage includes: a handle portion that remains against the upper surface of the beveled portion; and a pivot portion spaced apart from the handle portion, the linkage being oscillating about the pivot portion; when the actuating member moves from the first position to the second position or from the second position to the first position, the handle portion abuts against and slides against the upper surface of the beveled portion, and moves in the vertical direction, thereby causing the linkage to oscillate.

[0017] In one embodiment, the pivot engages below a crossbar mounted on the seat, allowing the linkage to swing about the crossbar.

[0018] In one embodiment, the anti-misuse mechanism further includes: a pusher disposed in the seat and restricted to vertical movement; the other end of the linkage relative to the handle is engaged with the upper end of the pusher, and the swinging of the linkage causes the pusher to move vertically.

[0021] In one embodiment, the anti-misuse mechanism further includes: a follower disposed in the turntable and restricted to move longitudinally; wherein the follower is connected to the drive member such that vertical movement of the drive member can drive longitudinal movement of the follower.

[0022] In one embodiment, the driven member has two longitudinally extending sidewalls and an open top, each sidewall having a groove with an active inclined edge symmetrically formed along the longitudinal direction; the driving member has driving pins extending laterally outward from opposite sides of the driving member, the driving pins being inserted into corresponding grooves and held against corresponding active inclined edges.

[0023] In one embodiment, the child safety seat further includes: a protrusion, at least partially disposed in the turntable, movable between a locked position extending from the turntable and an unlocked position retracted into the turntable; the protrusion is disposed on the outer side of the follower near the turntable, and longitudinal movement of the follower causes the protrusion to move between the locked position and the unlocked position.

[0024] In one embodiment, the anti-misuse mechanism further includes: a positioning spring disposed between the positioning member and the seat, biasing the positioning member upward; a pusher spring disposed between the pusher and the seat, biasing the pusher upward; and a drive spring disposed between the drive member and the turntable, biasing the drive member upward.

[0025] In one embodiment, the chute is an approximately right-angled triangular groove, with the hypotenuse of the right-angled triangle located on one longitudinal side of the chute and serving as the acting hypotenuse; the anti-misuse mechanism further includes a follower spring disposed between the follower and the turntable, biasing the follower to tend to move toward the outside of the turntable, thereby causing the follower to tend to drive the protrusion to extend out of the turntable.

[0026] In one embodiment, the turntable includes: a disc-shaped portion located below the turntable; the base includes: an opening located above the base and circular in shape, the disc-shaped portion being rotatably engaged in the opening; and a blocking portion located at the edge of the opening; when the protrusion is in a locked position, the protrusion and the blocking portion interfere with each other to limit the rotation range of the turntable relative to the base.

[0087] While this invention has been illustrated and described with reference to specific embodiments, it should not be limited to the details shown. Rather, various modifications to these details may be made within the scope of equivalents of the claims and without departing from the invention.

[0088] The descriptions of directions such as "front", "back", "up" and "down" used in this document are for ease of understanding only. This invention is not limited to these directions, but can be adjusted according to actual circumstances. Although this application has been described with reference to typical embodiments, the terminology used is illustrative and exemplary, and not restrictive.

[0089] Reference Figure 1 and Figure 2 The image shows a child safety seat 1 according to this application. The child safety seat 1 includes: a base 300, a turntable 200, a seat 400, and an anti-misuse mechanism 100.

[0090] The base 300 is located at the lower part of the child safety seat 1 and is used to secure the child safety seat 1 to a vehicle such as a car.

[0091] The turntable 200 is located above the base 300 and can rotate relative to the base 300 around a basic vertical axis between forward and backward positions.

[0092] Seat 400 is located above turntable 200 and can rotate with turntable 200. That is, turntable 200 allows seat 400 to switch between forward and backward positions. In this article, Figure 2 The forward position shown is the position where the turntable 200 makes the seat 400 face forward (in the direction of the vehicle's travel). Figure 1 The rearward position shown is the position where the turntable 200 makes the seat 400 face rearward.

[0093] An anti-misuse mechanism 100 is disposed between the base 300, the turntable 200, and the seat 400. The anti-misuse mechanism 100 can prevent or allow relative rotation between the turntable 200 and the base 300.

[0094] In some applications, the seat 400 is configured to be detachably engaged with the turntable 200. The anti-misuse mechanism 100 of this application is configured to allow for the separation and engagement of the seat 400 and the turntable 200.

[0095] Reference Figure 3 and Figure 4 The image shows seat 400 of child safety seat 1.

[0096] At least a portion of the anti-misuse mechanism 100 is installed in the seat 400, specifically inside the front side of the bottom end of the seat 400. The anti-misuse mechanism 100 includes an operating element 110 for receiving operation from the user. The operating element 110 is mounted on the seat 400 and can be operated from outside the seat 400.

[0097] More specifically, the operating element 110 can be positioned relative to the seat 400. Figure 3 The first position shown is Figure 4 The device moves between the second positions shown to switch the anti-misuse mechanism 100 between the locked and unlocked positions.

[0098] For example, in Figure 3 In the first position, the operating element 110 is positioned laterally to the right in the figure, locking the anti-misuse mechanism 100. At this time, the rotation range of the turntable 200 (and the seat 400) relative to the base 300 is limited, preventing the turntable 200 from rotating to the forward position. The principle behind this rotation range limitation will be described in more detail later. When the operating element 110 is in the first position, a marking on the operating element 110 is exposed on the outside of the seat 400 to indicate the current status of the anti-misuse mechanism 100 to the user. This marking may be, for example, "<15M," indicating that the current status is suitable for children under 15 months old.

[0099] exist Figure 4 In the second position, the operating element 110 is positioned laterally to the left in the figure, placing the anti-misuse mechanism 100 in the unlocked position. At this time, the rotation range of the turntable 200 (and the seat 400) relative to the base 300 is unrestricted, allowing the turntable 200 to rotate to either a forward or rearward position. When the operating element 110 is in the second position, another indicator of the operating element 110 is exposed on the outside of the seat 400 to indicate the current status of the anti-misuse mechanism 100 to the user. This indicator, for example, is ">15M," indicating that the current status is suitable for children older than 15 months.

[0100] Reference Figures 5 to 7 Describe the principle by which the anti-misuse mechanism 100 limits the rotation range of the turntable 200 relative to the base 300.

[0101] like Figure 5 As shown, the turntable 200 is mounted on the base 300 and can be configured to rotate about a generally vertical axis. Figure 6 As shown, the turntable 200 includes a disc-shaped portion 210 located below the turntable 200. At least a portion of the anti-misuse mechanism 100 is disposed in the turntable 200, and a protrusion 170 of the anti-misuse mechanism 100 can extend from the edge of the disc-shaped portion 210. Figure 7 As shown, the base 300 includes an opening 310 and a blocking portion 320. The opening 310 is located above the base 300 and is circular. The blocking portion 320 is located at the edge of the opening 310. It is easy to understand that the disc-shaped portion 210 rotatably engages with the opening 310. When the protrusion 170 is in the locked position, the protrusion 170 and the blocking portion 320 interfere with each other to limit the rotation range of the turntable 200 relative to the base 300. For example, the blocking portion 320 is arranged along the semicircle of the opening 310. When the protrusion 170 is in the locked position (i.e., protruding from the turntable 200), the protrusion 170 can only move within the range of the rear semicircle of the opening 310, thus the turntable 200 is restricted from rotating to the forward position.

[0102] Reference Figures 8 to 14 Describe the relationship between the components of the anti-misuse mechanism 100.

[0103] The anti-misuse mechanism 100 includes an operating component 110, a toggle part 111, a sliding part 112, a positioning component 120, a positioning component spring 129, a linkage part 130, a pushing component 140, a pushing component pin 148, a pushing component spring 149, a driving component 150, a driving component pin 158, a driving component spring 159, a driven component 160, a driven component spring 169, and a protrusion 170.

[0104] The operating element 110 is disposed in the seat 400 and, according to the user's operation, is laterally (perpendicularly) to the seat 400 between a first position and a second position. Figures 8 to 11 (The direction of the paper) moves. According to the design of this application, when the operating element 110 passes the intermediate position between the first position and the second position and moves towards the first position, the operating element 110 automatically moves to the first position; when the operating element 110 passes the intermediate position and moves towards the second position, the operating element 110 automatically moves to the second position. This will be explained in detail below.

[0105] The positioning element 120 is disposed on the seat 400 and abuts against the operating element 110, so as to automatically move the operating element 110 to the first position or the second position when the operating element 110 moves toward the first position or toward the second position, as will be described in detail below.

[0106] The positioning spring 129 is disposed between the positioning member 120 and the seat 400, and biases upward on the protrusion 121 of the positioning member 120.

[0107] The linkage 130 extends longitudinally toward the interior of the seat 400 and swings about a transverse axis (i.e., about the crossbar 410). The operating member 110 abuts against one end of the linkage 130 (i.e., the end where the handle 131 is located, see...). Figure 9 , 11 Furthermore, the lateral movement of the operating member 110 will cause the linkage 130 to swing. It should be understood that the linkage 130 can extend in different directions, such as extending in an inclined direction.

[0108] The pusher 140 is vertically positioned within the seat 400 and is restricted to vertical movement. The other end of the linkage 130, relative to the handle 131, engages with the upper end of the pusher 140, and the oscillation of the linkage 130 causes the pusher 140 to move vertically. It should be understood that the pusher 140 can be positioned and / or moved in other directions, such as obliquely positioned and / or obliquely moved.

[0109] The push pin 148 is inserted between the push member 140 and the linkage member 130 to allow the interaction between the push member 140 and the linkage member 130, which will be described in detail later.

[0110] The push spring 149 is located between the push member 140 and the seat 400, and biases the push member 140 upward.

[0111] The drive member 150 is disposed in the turntable 200, vertically below the pusher member 140, and is restricted to vertical movement. The lower end of the pusher member 140 abuts against the upper end of the drive member 150, and vertical movement of the pusher member 140 causes vertical movement of the drive member 150.

[0112] The drive spring 159 is positioned between the drive component 150 and the turntable 200, biasing the drive component 150 upwards.

[0113] It is understood that the drive member 150 and the pusher member 140 are located in the turntable 200 and the seat 400, respectively. When the turntable 200 is separated from the seat 400, the drive member 150 and the pusher member 140 also separate accordingly. When the seat 400 is engaged with the turntable 200, the pusher member 140 extends from the bottom of the seat 400 and enters the turntable 200 from the top of the turntable 200 in order to push the drive member 150 downward.

[0114] The follower 160 is disposed longitudinally in the turntable 200 and is restricted to move longitudinally. The follower 160 is connected to the drive member 150 such that the vertical movement of the drive member 150 can drive the longitudinal movement of the follower 160.

[0115] The follower spring 169 is disposed between the follower 160 and the turntable 200, biasing the follower 160 so that the follower 160 tends to move closer to the outside of the turntable 200, that is, the follower 160 tends to drive the protrusion 170 to extend out of the seat 400.

[0116] The protrusion 170 is at least partially disposed in the turntable 200 and is movable between a locked position extending out of the turntable 200 and an unlocked position retracted into the turntable 200. The protrusion 170 is disposed near the outside of the turntable 200 on the follower 160, and longitudinal movement of the follower 160 causes the protrusion 170 to move between the locked position and the unlocked position.

[0117] like Figure 8 and Figure 9 As shown, the anti-misuse mechanism 100 is in the unlocked position. At this time, the operating member 110 is in the first position, and the end of the linkage 130 that abuts against the operating member 110 is lifted upward. The end of the linkage 130 opposite to the operating member 110 is pressed downward, causing the pusher 140 to move downward. The pusher 140 presses down on the drive member 150, and the drive member 150 causes the follower 160 to move into the turntable 200. Therefore, the protrusion 170 provided to the drive member 150 retracts into the turntable 200.

[0118] like Figure 10 and Figure 11As shown, when the user moves the operating member 110 to the second position, the operating member 110 no longer pushes up the end of the linkage 130 that abuts against the operating member 110, and the end of the linkage 130 opposite to the operating member 110 no longer presses down on the pusher 140. Therefore, the pusher 140 returns to its original position under the action of the pusher spring 149, and drives the linkage 130 to rotate clockwise to its original position. Because the pusher 140 no longer presses down on the drive member 150, the drive member 150 returns to its original position under the action of the drive spring 159, and no longer drives the driven member 160 to move into the turntable 200. The driven member 160 returns to its original position outside the turntable 200 under the action of the driven spring 169, driving the protrusion 170 to extend out of the turntable 200, so that the anti-misuse mechanism 100 is in the locked position.

[0119] Reference Figures 12 to 15 Describe the structure of the operating component 110, the positioning component 120, and the pushing component 140.

[0120] like Figures 13 to 14 As shown, the operating member 110 includes a sliding part 112, a toggle part 111, two positioning recesses 113, a beveled part 114, and a ridge 115.

[0121] The sliding portion 112 extends laterally and can slide against the outer surface of the seat 400 (i.e., against the child safety seat 1). The actuating portion 111 is connected to the outer side of the sliding portion 112, exposed outside the seat 400, and can move the sliding portion 112 laterally relative to the seat 400. The outer side of the sliding portion 112 may have markings, and multiple markings may be located on both sides of the actuating portion 111 (see reference). Figure 3 and Figure 4 This allows the user to easily understand the status of the anti-misuse mechanism 100. It should be understood that the sliding portion 112 can also be configured to extend in other directions, such as vertically, diagonally, or curvedly. The sliding portion 112 can conform to the outer surface of the seat 400, or it can be embedded in the seat 400 or suspended outside the seat 400. The actuating portion 111 can be exposed on the outside of the seat 400 or hidden within the seat 400.

[0122] Two positioning recesses 113 are located inside the sliding portion 112, at the transverse midpoint of the sliding portion 112, and are symmetrical about the vertical center of the sliding portion 112. It should be understood that the two positioning recesses 113 may also be asymmetrically located on one transverse side of the sliding portion 112 or on both transverse sides of the sliding portion 112. Each positioning recess 113 extends in an arc shape relative to the sliding portion 112 from its transverse midpoint. A ridge 115 is formed between the two positioning recesses 113, protruding downwards relative to the positioning recesses 113. That is, the bottom surface of the operating member 110 forms a shape that is high on both sides and low in the middle along the transverse direction at the positioning recesses 113 and the ridge 115. The ridge 115 protrudes towards the positioning member 120 and abuts against the protrusion 121 of the positioning member 120, causing the operating member 110 to automatically move to the first position or the second position. The ridge 115 is arc-shaped towards the protrusion 121 to prevent jamming between the base 115 and the protrusion 121.

[0123] The beveled portion 114 is formed on the longitudinal inner side of the positioning recess 113, and the upper surface of the beveled portion 114 extends obliquely with one end higher and the other lower in the transverse direction. It should be understood that the beveled portion 114 can also be formed in different positions, such as vertically above, vertically below, on one side of the transverse direction of the positioning recess 113, or between the positioning recess 113 and the sliding portion 112, as long as it can abut against the handle portion 131 of the linkage 130.

[0124] like Figure 15 As shown, the positioning member 120 is located vertically below the operating member 110. In other embodiments, the positioning member 120 may also be located in other directions of the operating member 110, as long as the positioning recess 113 and the ridge 115 can abut against the protrusion 121. The positioning member 120 includes a positioning member body 122 and a protrusion 121. The positioning member body 122 is generally rectangular and disposed in the seat 400. The protrusion 121 is longitudinally movably disposed in the positioning member body 122 and has an arcuate protrusion 121 adapted to the positioning recess 113. The positioning member spring 129 biases the protrusion 121 upward. When the operating member 110 approaches the intermediate position, the protrusion 121 abuts against the ridge 115, causing the operating member 110 to automatically move to the first position or the second position. When the operating member 110 passes the intermediate position and approaches the first position or the second position, the protrusion 121 abuts against the corresponding positioning recess 113 and pushes the operating member 110 to the first position or the second position.

[0125] More specifically, the aforementioned intermediate position refers to the position where the ridge 115 of the operating member 110 corresponds exactly to the top of the arcuate protrusion 121.

[0126] like Figure 13 As shown, the linkage 130 includes a handle 131, a pivot 132, and a fork 133.

[0127] The handle 131 is located at one longitudinal end of the linkage 130 and remains abutting against the upper surface of the inclined portion 114. It should be understood that the handle 131 may also be formed at other positions of the linkage 130, such as at the vertical upper end, vertical lower end or lateral side of the linkage 130, as long as it abuts against the sliding portion 112.

[0128] The pivot portion 132 and the handle portion 131 are spaced apart, and the linkage 130 can swing around the pivot portion 132. More specifically, the pivot portion 132 is a laterally extending arcuate groove that opens upward and engages below the crossbar 410 mounted on the seat 400, so that the linkage 130 can swing around the crossbar 410. It should be understood that the pivot portion 131 can be located at the longitudinal middle of the linkage 130 or near either end of the linkage 130, and the pivot portion 132 can also be of other shapes, as long as it can pivotally engage with the crossbar 410.

[0129] The fork-shaped portion 133 is located at the other longitudinal end of the linkage 130, and has two support arms that extend longitudinally and are symmetrically arranged on both sides of the transverse side with respect to the longitudinal center of the pusher 140. The pusher 140 is pivotally connected between the two support arms by a pusher pin 148 (see [link]). Figure 9 and Figure 11 It should be understood that the outriggers can also extend in other directions, such as diagonally, and the two outriggers can be set asymmetrically.

[0130] When the operating member 110 moves from the first position to the second position or from the second position to the first position, the handle 131 abuts against and slides on the upper surface of the inclined portion 114 and moves in the vertical direction, thereby causing the linkage 130 to swing.

[0131] Figures 16 to 19 The interaction between the operating element 110, the positioning element 120, the linkage element 130, and the pushing element 140 is shown more clearly.

[0132] Reference Figures 20 to 24 Describe the specific structure of the follower 160.

[0133] like Figure 21 and Figure 22 As shown, the follower 160 is generally box-shaped, having two longitudinally extending sidewalls 161 and an open top. Each sidewall 161 has a groove 162 with an active hypotenuse symmetrically formed along its longitudinal direction. More specifically, the groove 162 is an approximately right-angled triangular groove, with the hypotenuse of the right-angled triangle located on one longitudinal side of the groove 162 and serving as the active hypotenuse. It should be understood that the follower 160 can also be of other shapes, as long as it can form the groove 162 and the fixing protrusion 170.

[0134] like Figure 23 and 24As shown, the drive member 150 is a hollow, generally cylindrical shape. Drive member pins 158 are provided on the drive member 150, extending laterally outward from opposite sides of the drive member 150. The drive member pins 158 are respectively inserted into corresponding sliding grooves 162 and remain abutting against the corresponding actuating inclined edges.

[0135] Reference Figure 23 and Figure 24 This allows for a clearer understanding of the interaction between the driving component 150, the driven component 160, and the protrusion 170.

[0136] Since this application can be embodied in various forms without departing from the spirit and substance of this application, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted in the broadest sense within the scope defined by the claims. Therefore, all variations falling within the scope of the claims or their equivalents should be covered by the claims.
