Description

[Technical Field]

[0001] The present disclosure relates to a carrier, a base, and a carrier application device. [Background technology]

[0002] Basket-type child car seats and other carriers are generally combined with a base and secured to a vehicle seat. Some baskets can also be directly connected to a vehicle seat via a seat belt or an anchoring device such as ISOFIX. However, baskets connected by a seat belt are not sufficiently stable and are prone to vibration. Furthermore, baskets connected by anchoring devices often have the problem of being unable to be used in combination with different vehicle seats in various vehicle models because the anchoring devices are not adjustable. Furthermore, while some anchoring devices are adjustable, their structure is complex and inconvenient to operate.

[0003] It should be noted that the above description of the prior art is merely intended to provide background, and is not an admission that the above description of the prior art constitutes prior art to the present disclosure, nor should any description of the above description of the prior art be construed as any part of the present disclosure. Summary of the Invention

[0014] Exemplary embodiments will now be described in detail with reference to the accompanying drawings.

[0015] 1 shows that a carrier 1 according to the present disclosure is connected to a vehicle seat 2, the carrier 1 is placed on a seat 2A of the vehicle seat 2, and a leading edge 1E of the carrier 1 abuts against a seat back 2B of the vehicle seat 2. Note that although the carrier 1 shown in the drawing is a basket-type child seat, the present disclosure is not limited thereto, and the carrier 1 according to the present disclosure may be for transporting people, animals, or goods, including, but not limited to, a basket-type child seat, a carrycot, a safety seat, an animal carrier, or an goods carrier.

[0016] For ease of explanation, this disclosure takes as an example that the carrier 1 is a basket-type child seat. As shown in FIGS. 5 and 10 , the basket-type child seat 1 includes a backrest 1A, a seating portion 1B, two side portions 1C located on both the left and right sides of the backrest 1A and the seating portion 1B, and a support seat 1D located under the basket 1. As shown in FIG. 2B , the basket-type child seat 1 may further include a handle 1F for lifting the basket 1. The position where the two side portions 1C of the basket 1 are connected to the handle 1F is a lifting point G. The lifting point G can be, for example, a rotation axis connecting the two side portions 1C of the basket 1 to the handle 1F.

[0017] Furthermore, when the baby is in the basket 1, the direction in which the backrest 1A faces is defined as "front," the opposite direction is defined as "rear," the left and right directions of the baby are defined as "sideways," the side of the basket 1 on which the baby is placed is defined as the "inside" of the basket 1, and the opposite side is defined as the "outside" of the basket 1. The structure of other forms of carrier 1 may be similar to or different from a basket-type child seat.

[0018] 2A and 2B , the carrier 1 may be provided with an anchor assembly 20 for safely and securely connecting the carrier 1 to the vehicle seat 2. The anchor joint 20 includes an anchor joint 20, and an engagement interface 20A of the anchor joint 20 can directly engage with a corresponding accessory on the vehicle seat 2, such as a connecting rod, a connecting ring, or an anchor interface (usually located at the connection point between the seat 2A and the seat back 2B of the vehicle seat 2), thereby eliminating the need for an additional base and making the connection of the carrier 1 to the vehicle seat 2 more convenient and the structure simpler. Depending on the actual situation of the vehicle seat 2, the engagement interface 20A of the anchor joint 20 may be lower than the seat surface of the seat 2A of the vehicle seat 2 or may be located at the connection point between the seat 2A and the seat back 2B of the vehicle seat 2, but the present disclosure is not limited thereto.

[0019] Movable support for anchor assembly

[0020] 3, to enable the carrier 1 to be stably connected to different vehicles, the anchor assembly according to the present disclosure further includes a movable support 10. The movable support 10 is attached to the carrier 1 and connected to the anchor joint 20 or is integrally formed with the anchor joint 20. Specifically, the movable support 10 and the anchor joint 20 may be separately manufactured components, and then connected by welding, riveting, screw connection, or the like. The movable support 10 and the anchor joint 20 may also be a single integrally formed component.

[0021] The movable support 10 may be installed so that a part or the whole of it can move relative to the carrier 1, thereby changing the distance of the anchor joint 20 connected to the movable support 10 relative to the carrier 1. The "movement" of a part or the whole of the movable support 10 relative to the carrier 1 may include a situation in which two members translate relative to each other, or a situation in which two threaded structures are threadedly engaged with each other and move axially, etc.

[0022] In one embodiment, the movable support 10 may be installed such that the sum of the exposed lengths of the movable support 10 and the anchor joint 20 exposed from the carrier 1 is greater than half of the total length of the movable support 10 and the anchor joint 20.

[0023] In another embodiment, the total length of the movable support 10 and anchor joint 20 is 350 mm, and the movable support 10 may be installed such that when the movable support 10 is fully extended, the total exposed length of the movable support 10 and anchor joint 20 exposed from the carrier 1 is 269 mm.

[0024] 2B , the leading edge 1E of the carrier 1 is defined as a reference line S1, a vertical line passing through the engagement interface 20A of the anchor joint 20 is defined as a joint line S2, and the distance of the joint line S2 from the reference line S1 is defined as T. When the joint line S2 is on the left side of the reference line S1 in the drawing, the distance T is positive, and when the joint line S2 is on the right side of the reference line S1 in the drawing, the distance T is negative. Thus, the movable support 10 can be installed such that when the engagement interface 20A of the anchor joint 20 is engaged with a corresponding accessory on the vehicle seat 2, the distance T of the joint line S2 from the reference line S1 in the fore-and-aft direction of the carrier 1 is within a range of 100 mm to -30 mm. That is, the movable support 10 may be installed such that, when the engagement interface 20A of the anchor joint 20 engages with a corresponding accessory on the vehicle seat 2, if the engagement interface 20A is located in front of the leading edge 1E of the carrier 1, the distance T of the engagement interface 20A to the leading edge 1E of the carrier 1 in the front-to-rear direction of the carrier 1 is 100 mm or less, and if the engagement interface 20A is located behind the leading edge 1E of the carrier 1, the distance T of the engagement interface 20A to the leading edge 1E of the carrier 1 in the front-to-rear direction of the carrier 1 is 30 mm or less. This ensures that, when the carrier 1 is connected to the vehicle seat 2, the anchor joint 20 is sufficiently engaged with the corresponding accessory on the vehicle seat 2, and the leading edge 1E of the carrier 1 can firmly abut against the seat back 2B of the vehicle seat 2.

[0025] In another embodiment, as shown in FIG. 30, a raised portion 1E1 may be provided on both sides of the leading edge 1E of the carrier 1, and the raised portion 1E1 is installed to increase the height on both sides of the leading edge 1E, thereby preventing the carrier 1 from tipping over.

[0026] It should be understood that the present disclosure is not limited to the above-described embodiments.

[0027] The direction of movement M of the movable support 10 is inclined with respect to the horizontal plane H.

[0028] 2B , the direction of movement M of the movable support 10 has an included angle α with respect to the horizontal plane H, and the included angle α can be set to be greater than 0° and equal to or less than 30°. In one embodiment, the included angle α of the direction of movement M of the movable support 10 with respect to the horizontal plane H can be 13°. Furthermore, the included angle α of the direction of movement M of the movable support 10 with respect to the horizontal plane H is the same as the included angle of each long groove 103 with respect to the horizontal plane H. The above numerical range of the included angle can enable the anchor assembly of the carrier 1 to be applicable to most vehicle seats 2.

[0029] Of course, the present disclosure is not limited thereto, and the included angle α of the moving direction M of the movable support 10 relative to the horizontal plane H can be set to any other suitable angle greater than 30° according to actual needs.

[0030] However, to ensure a more secure and stable connection of the carrier 1 to the vehicle seat 2 and to avoid a situation in which the included angle α is too large and causes the carrier 1 to tip over, as shown in FIG. 2B , the included angle α should be equal to or less than the included angle β of the connecting line N between the lifting point G of the carrier 1 and the engagement interface 20A of the anchor joint 20 relative to the horizontal plane H. Alternatively, the included angle θ of the connecting line N between the lifting point G of the carrier 1 and the engagement interface 20A of the anchor joint 20 relative to the movement direction M of the movable support 10 should be between 10° and 45°. Alternatively, if the carrier 1 is a basket-type child seat, in this embodiment, the included angle of the extension direction of the backrest 1A of the basket-type child seat relative to the movement direction M of the movable support 10 may be 32°. This arrangement not only ensures a more secure and stable connection of the carrier 1 to the vehicle seat 2, but also makes it easier for the user to lift the carrier 1 after the anchor joint 20 is unlocked.

[0031] Note that all included angles mentioned herein, including the included angle α of the movement direction M of the movable support 10 relative to the horizontal plane H, the included angle β of the connecting line N between the lifting point G of the carrier 1 and the engagement interface 20A of the anchor joint 20 relative to the horizontal plane H, and the included angle of the extension direction of the long groove 103 relative to the horizontal plane H, are relative to the horizontal plane H (see FIG. 2B ). If the carrier 1 tilts or overturns relative to the horizontal plane H, the movement direction M of the movable support 10, the connecting line N, and the extension direction of the long groove 103 will all tilt or overturn together with the carrier 1, resulting in difficult-to-evaluate changes in the included angles of the movement direction M of the movable support 10, the connecting line N, and the extension direction of the long groove 103 relative to the horizontal plane H, which clearly deviates from the design objective of this disclosure. Therefore, this disclosure will describe the setting ranges of the above included angles on the assumption that the carrier 1 is placed on a horizontal plane and remains fixed relative to the horizontal plane. The above-mentioned included angles are all inherent characteristics of the carrier 1 itself and will not change due to changes in the installation environment of the carrier 1. Specifically, in reality, the seating surface of the seat 2A of the vehicle seat 2 may be non-horizontal or elastic, and as a result, the carrier 1 on the seat 2A may not necessarily be positioned on the horizontal plane H. However, these factors do not change the above-mentioned included angles of the carrier 1 according to the present disclosure. Furthermore, the included angle α of the movement direction M of the movable support 10 of the carrier 1 according to the present disclosure relative to the horizontal plane H, the included angle β of the connecting line N between the lifting point G of the carrier 1 and the engagement interface 20A of the anchor joint 20 relative to the horizontal plane H, and the included angle of the extension direction of the long groove 103 relative to the horizontal plane H will not change due to factors such as whether the carrier 1 is positioned on a non-horizontal or elastic seating surface, or whether the carrier 1 tips over relative to the horizontal plane.

[0032] Meanwhile, the movable support 10 can also be installed so that the included angle α of the moving direction of the movable support 10 relative to the horizontal plane is variable. For example, in one embodiment, when the movable support 10 includes a movable part and an attachment part, and the movable part is movable relative to the carrier 1, the attachment part of the movable support 10 is rotatably attached to the carrier 1 (not shown), so that the included angle α of the moving direction of the movable support 10 relative to the horizontal plane can be changed as needed, thereby allowing the anchor joint 20 to better engage with corresponding accessories on different vehicle seats 2. Of course, as mentioned above, the included angle α of the moving direction of the movable support 10 relative to the horizontal plane should not exceed the included angle β of the connecting line N between the lifting point G of the carrier 1 and the engagement interface 20A of the anchor joint 20 relative to the horizontal plane H, thereby preventing the carrier 1 from tipping over. Similarly, it should be noted that the change in the included angle α of the direction of movement M of the movable support 10 relative to the horizontal plane H described here is caused only by the rotation of the movable support 10, and not by the carrier 1 being placed on a non-horizontal surface or elastic seating surface, or by the carrier 1 tipping over relative to the horizontal plane.

[0033] 1, when a user connects the carrier 1 to the vehicle seat 2, the user first moves the movable support 10 so that the anchor joint 20 is farthest from the carrier 1, then moves the anchor joint 20 toward a corresponding accessory on the vehicle seat 2, and finally engages with the corresponding accessory. Next, the user pushes the carrier 1 toward the seat back 2B of the vehicle seat 2 until the front edge 1E of the carrier 1 abuts against the seat back 2B of the vehicle seat 2, thereby ensuring that the carrier 1 is stably placed on the vehicle seat 2. Finally, the user positions the movable support 10 in that position so that it cannot move. This ensures that the carrier 1 is safely and securely connected to the vehicle seat 2.

[0034] 5 and 10, in an embodiment in which the movable support 10 as a whole is provided movably relative to the carrier 1, the carrier 1 is provided with a support guide portion 102 for guiding the movement of the movable support 10. The support guide portion 102 may employ various structures such as a slide groove, a guide rail, or a guide pin to guide the movement of the entire movable support 10. The support guide portion 102 may also be formed inside, between, and / or outside the components of the carrier 1.

[0035] In the embodiments shown in FIGS. 4, 5, 6, and 10, the support guide portion 102 may be formed as a housing extending along the outer surface of the support seat 1D of the carrier 1 in the front-to-rear direction, passing through the seat 1B, and protruding upward between the seat 1B and the side portion 1C. That is, the support guide portion 102 is arranged so that the maximum distance L1 between the two anchor joints 20 of the movable support 10 moving along the support guide portion 102 (i.e., the distance between the lateral outer surfaces of the two anchor joints 20) is equal to or less than the distance L2 (see FIG. 6) between the outer surfaces of the two side portions 1C of the carrier 1. This allows the movable support 10 to move stably without increasing the overall volume of the carrier 1, making the overall structure of the carrier 1 compact and, in particular, eliminating the need for additional space in the width direction (i.e., the left-right lateral direction). However, the present disclosure is not limited thereto.

[0036] In this embodiment, a part of the support guide part 102 located on the outer surface of the support seat 1D of the carrier 1 is a guide rail, and a part of the housing located within the seat 1B and formed between the seat 1B and the side part 1C has a slide groove formed therein for the movable support 10 to slide within. The inner contour of the slide groove may be formed to match the outer contour of the movable support 10. As shown in FIGS. 5 and 10 , the cross sections of the inner contour of the slide groove and the outer contour of the movable support 10 are approximately square, but the present disclosure is not limited thereto.

[0037] In another embodiment, the support guide portion 102 may be formed on the outside of a component of the carrier 1. For example, the support guide portion 102 may be a guide rail or a guide pin arranged on the outer surface of each side portion 1C of the carrier 1, and the entire movable support 10 is installed so as to be movably attached to the carrier 1 by engaging with the support guide portion 102.

[0038] In an embodiment in which a portion of the movable support 10 is movable relative to the carrier 1, the movable support 10 may be a structure consisting of two members (a movable portion and a mounting portion) (not shown) that are movable relative to each other, such as a telescoping structure, i.e., one portion of the movable support 10 (the movable portion) is movable relative to the other portion (the mounting portion). Here, the mounting portion is mounted to the carrier 1, and the movable portion is connected to the anchor joint 20. By moving the movable portion relative to the mounting portion and the carrier 1, the distance of the anchor joint 20 relative to the carrier 1 can be changed.

[0039] In the carrier 1 of the present disclosure, the distance of the anchor joint 20 relative to the carrier 1 can be changed, so that when used with different vehicle seats 2, the anchor joint 20 on the carrier 1 can extend an appropriate distance relative to the carrier 1, making it suitable for engaging with corresponding accessories on different vehicle seats 2.

[0040] It should be understood that although the anchor joint 20 is shown connected to the end of the movable support 10, the anchor joint 20 may be connected to any other suitable portion of the movable support 10 as long as the distance to the carrier 1 can be changed as the movable support 10 moves.

[0041] Furthermore, the connection between the anchor joint 20 and the movable support 10 may be a fixed connection or a movable connection. For example, the movable connection between the anchor joint 20 and the movable support 10 may be configured so that the anchor joint 20 is able to change its angle with respect to the movable support 10. This makes it easier for the anchor joint 20 to better engage with corresponding accessories on different vehicle seats 2. The movable connection may be a rotational connection or an elastic connection using an elastic member such as rubber or a spring.

[0042] In the drawings, two anchor assemblies are disposed, one on each side of the carrier 1. As shown in FIG. 3, a crossbar 11 is connected between the movable supports 10 of the two anchor assemblies. The crossbar 11 increases the strength of the anchor assemblies and simultaneously enables synchronous movement of the two movable supports 10. In one embodiment, the crossbar 11 is disposed below the movable supports 10 so as to be exposed from the bottom of the carrier 1. This allows a user to contact and operate an unlocking operation member 40 (described below) disposed on the crossbar 11.

[0043] To allow the crossbar 11 to move together with the movable support 10, the carrier 1 is provided with a long groove 103 for the crossbar 11 to move within. In the embodiment shown in Figures 4, 11, 27 and 29, the long groove 103 is formed in the support seat 1D of the carrier 1, and its extending direction is parallel to the moving direction M of the movable support 10. In one embodiment, the included angle of the extending direction of the long groove 103 with respect to the horizontal plane H can be set to be greater than 0° and less than or equal to 30°.

[0044] Of course, the present disclosure is not limited thereto, and the number of anchor assemblies may be one or more than two, and may be flexibly arranged according to actual needs.

[0045] Carrier Adjustment Device

[0046] The carrier 1 further includes an adjustment device 100. The adjustment device 100 is installed so as to adjust the distance of movement of the movable support 10 relative to the carrier 1. Specifically, when a user connects the carrier 1 to the vehicle seat 2, the adjustment device 100 adjusts the movable support 10 so that the movable support 10 is connected to the movable support 10 or can move relative to the carrier 1 until the integrally formed anchor joint 20 engages with a corresponding accessory on the vehicle seat 2. Furthermore, the adjustment device 100 can also position the movable support 10 at that distance to ensure that the carrier 1 is safely and securely connected to the vehicle seat 2.

[0047] However, the present disclosure is not limited thereto, and the carrier 1 may not include the adjustment device 100. For example, in one embodiment, when the movable support 10 includes a movable portion and an attachment portion, and the movable portion is movable relative to the carrier 1, the movable portion and the attachment portion may be connected with a screw, and the movable portion can be moved along the axial direction of the movable portion relative to the attachment portion by being twisted (not shown). When the user is ready to connect the carrier 1 to the vehicle seat 2, the user can twist the movable portion to move the movable portion of the movable support 10 along the axial direction relative to the attachment portion until the anchor joint 20 connected to or integrally formed with the movable portion engages with a corresponding accessory on the vehicle seat 2. In this case, the movable support 10 can be positioned at that distance without adjusting the movable support 10 with the adjustment device 100.

[0048] Hereinafter, an embodiment in which the carrier 1 according to the present disclosure uses the adjustment device 100 will be described in detail with reference to the drawings.

[0049] As shown in FIGS. 7 and 9, the adjustment device 100 may include at least two distance positioning members 110 disposed on the movable support 10 and a movable positioning member 120 disposed on the carrier 1. Here, the movable positioning member 120 can move between an engaged position and a disengaged position. As shown in FIG. 7, when the movable positioning member 120 is in the engaged position, it engages with one of the distance positioning members 110, thereby positioning the movable support 10 at that position and setting the distance of the movable support 10 relative to the carrier 1. Furthermore, as shown in FIG. 9, when the movable positioning member 120 is in the disengaged position, it is disengaged from the distance positioning member 110, thereby releasing the movable support 10 from its position and allowing it to move relative to the carrier 1.

[0050] It should be understood that the positions of the distance positioning member 110 and the movable positioning member 120 can be interchanged, i.e., the distance positioning member 110 can be disposed on the carrier 1, and the movable positioning member 120 can be disposed on the movable support 10. Also, the movement of the movable positioning member 120 between the engaged position and the disengaged position can be by pivoting, sliding, or a combination of pivoting and sliding.

[0051] In one embodiment, the movable positioning member 120 is a positioning hook pivotally arranged on the carrier 1, and the distance positioning member 110 is at least two positioning holes arranged on the movable support 10. It should be understood that the present disclosure is not limited thereto, and the movable positioning member 120 and the distance positioning member 110 may be, for example, two members that engage with each other through a recess and a groove, or may be composed of a pin shaft and a slot, etc.

[0052] For convenience of explanation, the positioning holes 110 and the positioning hooks 120 will be taken as an example.

[0053] The positioning hook 120 can be pivoted between an engaged position and a disengaged position. As shown in Figure 7, when the positioning hook 120 is pivoted to the engaged position, it engages with one of the positioning holes 110. As shown in Figure 9, when the positioning hook 120 is pivoted to the disengaged position, it disengages from the positioning hole 110.

[0054] The at least two positioning holes 110 can be arranged at equal or unequal intervals along the moving direction of the movable support 10. Thus, when the positioning hooks 120 engage with different positioning holes 110, the movable support 10 can be positioned at different distances relative to the carrier 1. This meets the needs of connecting the carrier 1 to different vehicle seats 2.

[0055] To facilitate user operation, the adjusting device 100 may further include an adjustment operation member 130. The adjustment operation member 130 is movably disposed on the carrier 1 and is installed so as to be able to drive the positioning hook 120 to move toward the disengaged position. The adjustment operation member 130 may take various structural forms, such as a handle, a wrench, a lever, a button, or a knob. Furthermore, the movement of the adjustment operation member 130 on the carrier 1 may be implemented in various forms, such as sliding, pivoting, or screwing, as long as it can drive the positioning hook 120 to move.

[0056] Of course, the adjusting device 100 may not include the adjusting operation member 130, and the positioning hook 120 may be installed so that a user can operate it by contacting the carrier 1 from the outside.

[0057] After the adjustment operating member 130 drives the positioning hook 120 to move to the disengaged position under user operation, the adjustment operating member 130 can be returned to its initial position by a return elastic member (not shown). It should be understood that the return elastic member is not essential and the adjustment operating member 130 may be configured to return to its initial position under user operation.

[0058] 7 and 9, the adjustment device 100 may further include an interlocking member 140. A first end 141 of the interlocking member 140 is connected to the adjustment operating member 130, and a second end 142 of the interlocking member 140 is directly or indirectly connected to the positioning hook 120, so that the adjustment operating member 130 drives the positioning hook 120 via the interlocking member 140.

[0059] The interlocking member 140 may be a flexible member made of various materials such as silk thread, string, rope, etc. that can withstand tensile force, or it may be a rigid member in the form of a rod, plate, or block.

[0060] Of course, the adjustment device 100 may not include the interlocking member 140, and the adjustment operating member 130 may be directly connected to and driven by a movable positioning member such as the positioning hook 120, but in such a case, the positioning position of the adjustment operating member 130 on the carrier is not as flexible as when the interlocking member 140 is included.

[0061] 7 and 9, the positioning hook 120 may be provided with a drive unit 121. The drive unit 121 is directly or indirectly connected to the second end 142 of the interlocking member 140. Of course, the present disclosure is not limited thereto. More specifically, the positioning hook 120 may not be provided with a drive unit 121. In such a case, the second end 142 of the interlocking member 140 may be directly or indirectly connected to the main body of the positioning hook 120, as long as the interlocking member 140 can drive the positioning hook 120 to move.

[0062] In one embodiment, adjustment operating member 130 is a rotatable knob, and linkage member 140 is a pull rope wrapped around knob 130. By rotating knob 130, a user can wrap pull rope 140 more around knob 130, thus pulling pull rope 140 and driving positioning hook 120 connected to second end 142 of pull rope 140.

[0063] Hereinafter, with reference to the drawings, particularly FIG. 12, an example will be described in which the adjustment operation member 130 is a handle that is slidably disposed on the carrier 1 and that can be slid by a pulling operation by the user.

[0064] In one embodiment, the adjustment operation member 130 is disposed on the outer surface of the carrier 1 (see FIG. 11), and the interlocking member 140 extends between the two side portions 1C of the carrier 1 (see FIG. 10). In this embodiment, either the first end 141 of the interlocking member 140 or the adjustment operation member 130 must first pass through the carrier 1 to connect to the other.

[0065] 6, 8, and 10, the carrier 1 is provided with an elongated connecting groove 101 penetrating the position where the adjusting operation member 130 is to be disposed. The protruding post 131 on the adjusting operation member 130 passes through the connecting groove 101, and the first end 141 of the interlocking member 140 is connected to the protruding post 131. Furthermore, when the adjusting operation member 130 is moving, the protruding post 131 on the adjusting operation member 130 can slide within the connecting groove 101.

[0066] In yet another embodiment, a screw 132 may be connected to the protruding post 131 (see FIG. 12 ), and the diameter of the cap of the screw 132 is greater than the width of the connecting groove 101. When the adjusting / operating member 130 is attached to the carrier 1, the protruding post 131 passes through the connecting groove 101, and then the screw 132 is connected to the protruding post 131. The screw 132 prevents the protruding post 131 of the adjusting / operating member 130 from detaching from the connecting groove 101, thereby preventing the adjusting / operating member 130 from detaching from the carrier 1.

[0067] Locking and unlocking the anchor joint

[0068] To facilitate a user's manipulation of the anchor joint 20 of the anchor assembly to switch between the locked state and the unlocked state, the anchor assembly further includes an unlock drive member 30 and an unlock operation member 40, as shown in Figures 12 to 21.

[0069] Here, the unlocking drive member 30 is disposed on the movable support 10 and can slide along the movable support 10 between a driving position (see FIGS. 13 and 19) and a non-driving position (see FIGS. 14 and 21). After the anchor joint 20 enters the locked state, the unlocking drive member 30 slides to the driving position. Also, when the unlocking drive member 30 slides to the non-driving position, it enables the anchor joint 20 to enter the unlocked state.

[0070] The unlocking operation member 40 is operatively connected to the unlocking drive member 30 and is arranged so as to be able to drive the unlocking drive member 30 to slide to the non-driven position.

[0071] 13, the unlock operation member 40 is connected to and driven by the unlock drive member 30 via a transmission member 50. However, the present disclosure is not limited to this, and the transmission member 50 may be omitted, and the unlock operation member 40 may be directly connected to and driven by the unlock drive member 30.

[0072] As shown in Figures 13 and 14, a central portion 51 of the transmission member 50 is pivotally attached to the movable support 10, a first end 52 of the transmission member 50 is connected to the unlocking operation member 40, and a second end 53 of the transmission member 50 is directly or indirectly connected to the unlocking drive member 30.

[0073] The first end 52 and the second end 53 of the transmission member 50 can rotate around the rotational connection portion of the central portion 51. As a result, when a user operates the unlocking operation member 40, the movement of the unlocking operation member 40 is transmitted to the unlocking drive member 30 via the transmission member 50.

[0074] 14, when a user applies an acting force to the unlock operation member 40 in the second rotation direction R2, the first end 52 of the transmission member 50 connected to the unlock operation member 40 pivots in the second rotation direction R2 along with the unlock operation member 40, and the second end 53 of the transmission member 50 connected to the unlock drive member 30 also pivots in the second rotation direction R2. This allows the second end 53 to drive the unlock drive member 30 to slide along the movable support 10 to the non-driven position, thereby enabling the anchor joint 20 to be placed in the unlocked state.

[0075] On the other hand, when the anchor joint 20 is placed in the locked state, the unlock drive member 30 slides to the drive position along the movable support 10 by the drive of a sliding member 22 (described later) connected thereto, without the user applying any force to the unlock operation member 40. As shown in FIG. 13 , the second end 53 of the transmission member 50 is pivoted in the first rotational direction R1 by the drive of the unlock drive member 30, and the first end 52 of the transmission member 50 is also pivoted in the first rotational direction R1, whereby the first end 52 drives the unlock operation member 40 to pivot in the first rotational direction R1.

[0076] Although the transmission member 50 in FIGS. 13 and 14 has a cylindrical shape, the present disclosure is not limited thereto, and the transmission member 50 can adopt various structures such as a sheet shape or a rod shape.

[0077] 13 and 14 also show an embodiment in which the second end 53 of the transmission member 50 is indirectly connected to the unlocking drive member 30. Here, a latch 54 passes through the second end 53 of the transmission member 50, the slot 12 of the movable support 10, and the connecting hole 31 of the unlocking drive member 30, so that the second end 53 of the transmission member 50 is connected to and drives the unlocking drive member 30 via the latch 54. In order to facilitate the second end 53 of the transmission member 50 being pivoted toward the first rotation direction R1 or the second rotation direction R2, the slot 12 of the movable support 10 is arranged as an arc-shaped elongated groove so that the latch 54 can slide within the slot 12.

[0078] In another embodiment, the latch 54 may be integrally formed with the second end 53 of the transmission member 50. This allows the second end 53 of the transmission member 50 to be directly connected to the unlocking drive member 30, thereby driving the unlocking drive member 30.

[0079] It should be understood that in the carrier 1 according to the present disclosure, the adjustment operation member 130 and the unlocking operation member 40 are functionally interchangeable. That is, the adjustment operation member 130 can be installed to drive the unlocking drive member 30 to slide toward the non-driven position, and the unlocking operation member 40 can be installed to drive the positioning hook 120 to move toward the disengaged position; for this purpose, only the related members need to be slightly modified based on the above embodiment.

[0080] As shown in FIGS. 15 to 21, an anchor joint 20 of the anchor assembly includes a joint support 21, a sliding member 22, and a locking hook .

[0081] Here, the joint support 21 is connected to the movable support 10. The sliding member 22 is slidably installed within the joint support 21 and connected to the unlocking drive member 30 so as to slide together with the unlocking drive member 30 between a driving position and a non-driving position. In one embodiment, the joint support 21 is provided with a fixed pin 21A, and the sliding member 22 is provided with a corresponding elongated fixed pin sliding groove 22C for the fixed pin 21A to slide within, thereby guiding the sliding member 22 to slide within the joint support 21 and preventing the sliding member 22 from detaching from the joint support 21.

[0082] The locking hook 23 is disposed on the joint support 21 so as to be rotatable between a locked position and an unlocked position to lock or unlock a corresponding accessory on the vehicle seat 2. Specifically, during the locking process, as shown in FIG. 19 , when the anchor joint 20 engages with a corresponding accessory, such as a connecting rod, connecting ring, or anchor interface (not shown) on the vehicle seat 2, the corresponding accessory enters the engagement interface 20A of the anchor joint 20. During this process, the corresponding accessory drives the locking hook 23 to rotate to the locked position, and the locking hook 23 locks the corresponding accessory. Furthermore, when the locking hook 23 rotates to the locked position, the sliding member 22 slides to the driving position by the driving of a sliding member return elastic member 25 (described later), and also slides the unlocking driving member 30 to the driving position. During the unlocking process, as shown in FIG. 21 , when the sliding member 22 slides to the non-driving position, the locking hook 23 becomes rotatable toward the unlocked position, and the corresponding accessory is unlocked.

[0083] 15 and 17A to 17B, the anchor joint 20 may include a lock hook return elastic member 24 to rotate the lock hook 23 toward the unlocked position. The lock hook return elastic member 24 is installed to drive the lock hook 23 to rotate toward the unlocked position.

[0084] In one embodiment, the lock hook return elastic member 24 is a torsion spring disposed about the rotation axis 23B of the lock hook 23 (see FIGS. 17A and 17B). A first end 24A of the torsion spring may be connected to the lock hook 23, and a second end 24B of the torsion spring may be connected to the joint support 21. It should be understood that the present disclosure is not limited thereto, and the lock hook return elastic member 24 may employ other forms of elastic members as long as they can rotate the lock hook 23 toward the unlocked position.

[0085] 17A , 17B , 19 and 21 , in order to prevent the risk of the carrier 1 being detached from the vehicle seat 2 due to accidental unlocking between the anchor joint 20 and a corresponding accessory of the vehicle seat 2, when the anchor joint 20 is in a locked state, i.e., when the locking hook 23 is in a locked position, the anchor joint 20 may include a sliding pin 22A connected to the sliding member 22, and the locking hook 23 is provided with a corresponding recess 23A that engages with the sliding pin 22A. The recess 23A of the locking hook 23 is configured so that, when the locking hook 23 is rotated to the locked position, as shown in FIG. 19 , the sliding pin 22A of the sliding member 22 engages with the recess 23A of the locking hook 23 to prevent the locking hook 23 from rotating to the unlocked position and hold the locking hook 23 in the locked position. When it is necessary to unlock the anchor joint 20, as shown in FIG. 21, the sliding member 22 slides to the non-driven position, and the sliding pin 22A of the sliding member 22 disengages from the recess 23A of the lock hook 23, causing the lock hook 23 to rotate to the unlocked position due to the action of the lock hook return elastic member 24.

[0086] In order to facilitate the sliding pin 22A to slide together with the sliding member 22 within the joint support 21, the joint support 21 is provided with a corresponding elongated sliding pin sliding groove 21B for the sliding pin 22A to slide within, thus guiding the sliding member 22 to slide within the joint support 21 and preventing the sliding member 22 from coming off the joint support 21.

[0087] In one embodiment, the anchor joint 20 may further include a sliding member return elastic member 25. The sliding member return elastic member 25 is installed to drive the sliding member 22 to slide toward the driving position. As shown in FIGS. 19 and 21 , the sliding member return elastic member 25 may be disposed between the fixed pin 21A of the joint support 21 and the inner wall of the sliding member 22. As shown in FIG. 19 , when the sliding member 22 and the unlocking drive member 30 are in the driving position, the distance between the fixed pin 21A of the joint support 21 and the inner wall of the sliding member 22 is at its maximum, and the sliding member return elastic member 25 is in a relatively small stress state. Therefore, the sliding member return elastic member 25 applies a relatively small acting force to the sliding member 22, which helps to maintain the sliding member 22 in the driving position so that the sliding pin 22A of the sliding member 22 remains engaged with the recess 23A of the lock hook 23. As shown in FIG. 21, when the sliding member 22 slides to the non-driving position, the distance between the fixed pin 21A of the joint support 21 and the inner wall of the sliding member 22 is minimum, and the elastic member 25 for returning the sliding member is under a relatively large stress state, so that the elastic member 25 for returning the sliding member applies a relatively large acting force to the sliding member 22, which causes the sliding member 22 to slide toward the driving position.

[0088] The overall operation process of the anchor joint 20, the unlocking drive member 30, and the unlocking operation member 40 will now be described.

[0089] During the locking process, the user engages the anchor joint 20 with a corresponding accessory, such as a connecting rod, connecting ring, or anchor interface, on the vehicle seat 2, and the corresponding accessory enters the engagement interface 20A of the anchor joint 20. During this process, the corresponding accessory drives the lock hook 23 to rotate to the locked position, and the lock hook 23 locks the corresponding accessory. When the lock hook 23 rotates to the locked position, the sliding member 22 slides to the driven position by the sliding member return elastic member 25. Also, as shown in FIG. 19 , the unlocking driving member 30 connected to the sliding member 22 also slides to the driven position. As a result, when the sliding member 22 slides to the driven position, the sliding pin 22A of the sliding member 22 enters a position where it engages with the recess 23A of the lock hook 23, preventing the lock hook 23 from rotating toward the unlocked position and maintaining the lock position, as shown in FIG. 19 . When the unlock drive member 30 slides to the driving position, as shown in FIG. 13, the second end 53 of the transmission member 50 is pivoted toward the first rotational direction R1 by the driving of the unlock drive member 30, and the first end 52 of the transmission member 50 is also pivoted toward the first rotational direction R1, and the first end 52 drives the unlock operation member 40 to pivot toward the first rotational direction R1.

[0090] 14, during the unlocking process, the user applies a force to the unlocking operation member 40 in the second rotational direction R2, causing the first end 52 of the transmission member 50 connected to the unlocking operation member 40 to pivot in the second rotational direction R2 along with the unlocking operation member 40, and the second end 53 of the transmission member 50 connected to the unlocking drive member 30 to similarly pivot in the second rotational direction R2, thereby driving the unlocking drive member 30 to slide along the movable support 10 to the non-drive position. Then, the sliding member 22 connected to the unlocking drive member 30 similarly slides to the non-drive position. When the sliding member 22 similarly slides to the non-drive position, as shown in FIG. 21, the sliding pin 22A of the sliding member 22 disengages from the recess 23A of the locking hook 23, and the locking hook 23 rotates to the unlock position due to the action of the locking hook return elastic member 24, thereby unlocking the corresponding accessory.

[0091] To improve the appearance of the anchor joint 20, the anchor joint 20 further includes a joint housing 26. The joint housing 26 accommodates the joint support 21, the sliding member 33 and the locking hook 23 therein.

[0092] After the joint housing 26 is attached to the anchor joint 20, it is difficult for a user to determine whether the anchor joint 20 is in a locked or unlocked state. For this reason, in one embodiment, the anchor joint 20 according to the present disclosure is further provided with an indicator device. As shown in FIG. 15 , the joint housing 26 has an indicator window 26A that penetrates the joint housing 26. Meanwhile, as shown in FIGS. 15 , 16 , and 17A , the sliding member 22 is provided with an indicator member 22B. The indicator member 22B includes a first region 22B1 and a second region 22B2 that are adjacent to each other. The first region 22B1 and the second region 22B2 may have different colors or patterns to indicate that the anchor joint 20 is in a locked or unlocked state, respectively. The indicator member 22B can slide along with the sliding member 22, thereby switchably exposing the first region 22B1 and the second region 22B2 from the indicator window 26A, thereby indicating the status of the anchor joint 20 to the user.

[0093] Specifically, the first region 22B1 may be set to green or may have the word "LOCK" printed on it to indicate that the anchor joint 20 is in a locked state, and the second region 22B2 may be set to red or may have the word "UNLOCKED" printed on it to indicate that the anchor joint 20 is in an unlocked state. When the sliding member 22 slides to the driven position in accordance with the unlocking drive member 30, the green color of the first region 22B1 or the word "LOCKED" is exposed through the indicator window 26A, indicating to the user that the anchor joint 20 is in a locked state. When the sliding member 22 slides to the non-driven position in accordance with the unlocking drive member 30, the red color of the second region 22B2 or the word "UNLOCKED" is exposed through the indicator window 26A, indicating to the user that the anchor joint 20 is in an unlocked state.

[0094] Connecting pillar

[0095] The carrier 1 according to the present disclosure can be connected not only to a vehicle seat 2 but also to an application device (see FIGS. 92 to 100). In this specification, the application device may also be referred to as a carrier application device, and refers to a device on which the carrier 1 can be placed or applied, including, but not limited to, a stroller for carrying a baby, a baby chair, a cart for carrying a child, or a cart for goods or animals.

[0096] 2A and 2B, to facilitate connection between the carrier 1 and the carrier applying device, the carrier 1 is provided with connecting posts 200. The connecting posts 200 on the carrier may be installed to be movable between an extended position and a retracted position so as to engage with corresponding accessories on the carrier applying device, thereby allowing a user to easily connect and disconnect the carrier 1 to the carrier applying device.

[0097] In one embodiment, the connecting post 200 is configured to be driven by the adjustment operation member 130. That is, a user can adjust both the movable support 10 and the connecting post 200 by operating the adjustment operation member 130. This configuration not only makes user operation more convenient, but also reduces the number of parts on the carrier 1 and simplifies the structure. Of course, the present disclosure is not limited thereto. In another embodiment, the connecting post 200 may be operated by a user independently of the adjustment operation member 130.

[0098] In this specification, a configuration will be described in which the connecting post 200 is driven by the adjusting operation member 130 to move toward the retracted position. Meanwhile, as shown in Figures 23B and 25B, a connecting post return elastic member 202 is provided on the carrier 1. The connecting post return elastic member 202 is installed so as to move the connecting post 200 toward the extended position.

[0099] 7 and 9, the adjustment device 100 of the carrier 1 further includes a driving member 150. The driving member 150 is connected between the second end 142 of the interlocking member 140 and the driving part 121 of the positioning hook 120, and is movably installed on the carrier 1. In this embodiment, the driving part 121 is indirectly connected to the second end 142 of the interlocking member 140. The movement of the driving member 150 on the carrier 1 can take various forms, such as sliding, rotating, or a combination of sliding and rotating, as long as the acting force of the interlocking member 140 can be transmitted to the positioning hook 120.

[0100] Specifically, in the embodiment shown in FIGS. 7, 8, and 23B to 25B, the entraining member 150 includes a front entraining member portion 151 and a rear entraining member portion 152 connected to each other by a T-shaped recess-and-protrusion fitting (see FIGS. 23B and 25B). Here, the front entraining member portion 151 is connected to the second end 142 of the interlocking member 140, and the rear entraining member portion 152 is provided with an elongated entraining groove 152A into which the drive part 121 of the positioning hook 120 is inserted. The entraining groove 152A is positioned so that an acting force can be applied to the drive part 121 to pivot the positioning hook 120 between the engaged position and the disengaged position. Naturally, the present disclosure is not limited thereto. More specifically, the front entraining member portion 151 and the rear entraining member portion 152 of the entraining member 150 may be connected in various ways, such as by screw connection or riveting, or the entraining member 150 may be a single member. Also, the entraining member 150 can adopt other structural forms to drive the positioning hook 120 .

[0101] To realize that the connecting post 200 can be driven by the adjusting operation member 130, the entraining member 150 and the connecting post 200 may be installed so as to be able to drive and move relative to each other.

[0102] 23B and 25B, the entraining member front part 151 is provided with a driving ramp 151A, and the connecting post 200 is provided with a driving protrusion 201. The driving ramp 151A and the driving protrusion 201 abut against each other, so that either the entraining member front part 151 or the connecting post 200 can drive the other to move.

[0103] When the user acts on the adjusting operation member 130, the adjusting operation member 130 drives the entraining member 150 via the interlocking member 140, moving it to the right in the figure, and the entraining groove 152A of the entraining member rear part 152 drives the driving part 121 of the positioning hook 120, so that the positioning hook 120 moves toward the disengagement position and disengages from one of the positioning holes 110, so that the movable support 10 can move relative to the carrier 1. At the same time, as shown in FIG. 23B , the driving inclined surface 151A on the entraining member front part 151 presses the driving protrusion 201 on the connecting post 200, so that the connecting post 200 moves toward the retracted position (downward in FIG. 23B ) and retracts into the carrier 1, allowing the carrier 1 to be detached from the carrier applying device.

[0104] 25B , the connecting post 200 protrudes outward from the carrier 1 and moves toward the extended position (the upper part of FIG. 25B ) under the action of the connecting post return elastic member 202, thereby enabling the carrier 1 to be connected to the carrier application device. At the same time, the driving protrusion 201 on the connecting post 200 presses the driving inclined surface 151A on the leading member front part 151, causing the leading member 150 to move toward the left in the figure, and the driving groove 152A on the leading member rear part 152 drives the driving part 121 of the positioning hook 120, causing the positioning hook 120 to move toward the engagement position and engage with one of the positioning holes 110, thereby positioning the movable support 10 relative to the carrier 1.

[0105] It should be understood that the present disclosure is not limited thereto, and the driving ramp 151A may be disposed on the connecting post 200, and the driving lug 201 may be disposed on the entraining member front part 151. Alternatively, both the entraining member front part 151 and the connecting post 200 are provided with driving ramps 151A that abut against each other.

[0106] Connection Hook

[0107] 2A and 2B, in order to facilitate connection between the carrier 1 and the carrier applying device, the carrier 1 is provided with a connection hook 300. The connection hook 300 on the carrier may be installed to be movable between a connected position and a disconnected position so as to engage with a corresponding accessory on the carrier applying device, thereby allowing a user to easily connect and disconnect the carrier 1 to the carrier applying device.

[0108] 27 and 29, the connection hook 300 may be installed to be connected to the adjustment operation member 130 so that the adjustment operation member 130 can drive the connection hook 300 through a user's operation. That is, when a user operates the adjustment operation member 130, the movable support 10 can be adjusted or the connection hook 300 can be driven. This not only makes the user's operation more convenient, but also reduces the number of parts on the carrier 1 and simplifies the structure. Naturally, the present disclosure is not limited thereto, and in another embodiment, the connection hook 300 may be configured to be operated by a user independently of the adjustment operation member 130.

[0109] It should be understood that the adjustment operating member 130 may be configured to drive the connection hook 300 to move toward the connected position and / or the disconnected position. In one embodiment, the adjustment operating member 130 is configured to drive the connection hook 300 to move toward the disconnected position, and at the same time, the connection hook 300 is configured to be driven by another member to move toward the connected position. For example, the carrier 1 may include a connection hook restoring elastic member 301, which biases the connection hook 300 toward the connected position.

[0110] In this specification, an example will be described in which the connection hook 300 is driven by the adjustment operation member 130 to move toward the non-connected position, and is biased by the connection hook return elastic member 301 to move toward the connected position.

[0111] As shown in FIGS. 12, 27 and 29, the connection hook restoring elastic member 301 may be an elastic sheet disposed on the connection hook 300, and the elastic sheet may be in contact with the carrier 1.

[0112] When the user acts on the adjustment operating member 130, as shown in FIG. 29, the adjustment operating member 130 moves and drives the connection hook 300 so that the connection hook 300 is pivoted toward the disconnected position, thereby disengaging the carrier 1 from the carrier application device.

[0113] 27, when the user stops acting on the adjustment operation member 130, the connection hook 300 is pivoted toward the connection position by the elastic force of the elastic sheet 301 abutting against the carrier 1, thereby connecting the carrier 1 to the carrier application device. At the same time, the adjustment operation member 130 connected to the connection hook 300 is driven by the connection hook 300 to return to its initial position.

[0114] Second embodiment of carrier adjustment device

[0115] 31 to 42 show a second embodiment of the carrier adjustment device according to the present disclosure, and the main difference from the embodiment of the adjustment device described above with reference to FIGS. 7 to 9 is that in the second embodiment, an adjustment execution member 160 is used instead of the adjustment operation member 130, and correspondingly, the structure and drive method of the movable positioning member 120 are changed in the second embodiment.

[0116] Specifically, the second embodiment of the adjustment device 100 may include an adjustment execution member 160 that is positioned to directly or indirectly drive the movable positioning member 120 to move it toward the disengaged position.

[0117] 31 to 35, the adjustment execution member 160 is an adjustment button arranged on a crossbar 11 that is installed between two movable supports 10. The crossbar 11 can be arranged below the movable supports 10 so as to be exposed from the bottom of the carrier 1, so that a user can easily touch and operate the adjustment button 160 arranged on the crossbar 11.

[0118] However, the present disclosure is not limited thereto. The adjustment execution member 160 may take various structural forms, such as a handle, a wrench, a lever, a knob, etc., and may be located on the carrier 1 or at another position, as long as it can drive the movable positioning member 120 to move toward the disengaged position.

[0119] In the second embodiment of the adjustment device 100, as shown in Figures 34, 36, 37 and 39, the movable positioning member 120 is a positioning post that is movably disposed relative to the fixed seat 60, and the fixed seat 60 is fixed to the carrier 1. It should be understood that the movable positioning member 120 can be movably disposed on the carrier 1 without the fixed seat 60.

[0120] The at least two distance positioning members 110 are at least two positioning holes provided in each of the movable supports 10. The at least two positioning holes 110 are provided at equal or unequal intervals along the movement direction of each of the movable supports 10.

[0121] The positioning post 120 is installed so as to be movable between an engaged position and a disengaged position. As shown in Figures 34 and 36, when the positioning post 120 is moved to the engaged position, it engages with one of the positioning holes 110, thereby positioning the corresponding movable support 10 at that position. When the positioning post 120 is moved to the disengaged position, it disengages from the positioning hole 110, so that the movable support 10 is released from positioning and can move relative to the carrier 1.

[0122] To enable the positioning post 120 disposed on the fixed seat 60 to move between the engaged position and the disengaged position, as shown in FIGS. 37 and 39 , the fixed seat 60 is provided with a positioning post guide portion 601 through which the positioning post 120 moves. Naturally, the present disclosure is not limited thereto. The fixed seat 60 may be provided with other structures for guiding the movement of the positioning post 120 between the engaged position and the disengaged position. For example, one of the fixed seat 60 and the positioning post 120 may be provided with a pin shaft, and the other may be provided with a sliding groove along which the pin shaft slides, and the movement of the positioning post 120 may be guided by the engagement between the pin shaft and the sliding groove.

[0123] To realize that the adjustment execution member 160 drives the positioning column 120 , the second embodiment of the adjustment device 100 further includes a positioning member driving rod 122 and a traction member 170 .

[0124] 31, 34, 37 and 39, the fixed seat 60 is provided with a positioning member drive rod 122 that can drive the positioning post 120 to move between the engaged position and the disengaged position. A pivot end 122A of the positioning member drive rod 122 is pivotally mounted to the fixed seat 60, and a central portion of the positioning member drive rod 122 is movably connected to the positioning post 120, so that the pivoting movement of the positioning member drive rod 122 can move the positioning post 120.

[0125] More specifically, as shown in FIGS. 37 and 39 , an elongated drive rod slot 122B is provided in the center of the positioning member drive rod 122. A corresponding positioning post pin hole 125 is provided in the positioning post 120. By inserting a pin shaft (not shown) through the drive rod slot 122B and the positioning post pin hole 125, the pivotal movement of the positioning member drive rod 122 can move the positioning post 120. To facilitate the movement of the pin shaft, as shown in FIGS. 37 and 39 , the positioning post guide portion 601 of the fixed seat 60 is further provided with an elongated positioning post guide portion slot 601A through which the pin shaft passes. Naturally, the present disclosure is not limited thereto, and the positioning member drive rod 122 can drive and move the positioning post 120 in other ways. For example, the positioning member drive rod 122 can be connected to the positioning post 120 by a steel wire to drive and move the positioning post 120.

[0126] The adjustment execution member 160 and the positioning member drive rod 122 are connected and driven by a traction member 170. As shown in Figures 31 and 34, a first end of the traction member 170 is connected to the adjustment execution member 160, and a second end of the traction member 170 is connected to the free end 122C of the positioning member drive rod 122.

[0127] When an adjustment execution member 160, such as an adjustment button, is operated, the positioning member drive rod 122 is pivoted toward the disengagement direction via the traction member 170 (i.e., in FIG. 31, the free end 122C of the positioning member drive rod 122 moves downward), thereby driving the positioning column 120 to move toward the disengagement position.

[0128] It should be understood that, although in the above-described embodiment, the adjustment execution member 160 indirectly drives the positioning post 120 to move toward the disengaged position via the traction member 170 and the positioning member drive rod 122, the adjustment execution member 160 may also be disposed adjacent to the positioning post 120 and directly drive the positioning post 120.

[0129] In another embodiment, the positioning member drive rod 122 may not be installed, and the second end of the traction member 170 may be directly connected to the positioning post 120 so that the traction member 170 can directly drive the positioning post 120 to move toward the disengaged position.

[0130] The fixed seat 60 is further provided with a positioning member return elastic member 123, which is installed to directly or indirectly drive the positioning post 120 to move toward the engagement position. In the embodiment shown in Figures 36, 37, and 39, the positioning member return elastic member 123 may be a positioning member return torsion spring, which is installed to pivot the positioning member drive rod 122 in the engagement direction, thereby driving the positioning post 120 to move toward the engagement position. Of course, the positioning member return elastic member 123 may also be an elastic member with other structures, such as a spring or hydraulic rod, which is installed to directly drive the positioning post 120 to move toward the engagement position.

[0131] When connecting the carrier 1 to the vehicle seat 2, the user can first move the movable support 10 to extend relative to the carrier 1 so that the anchor joint 20 moves away from the carrier 1, which allows the user to easily engage the anchor joint 20 with a corresponding accessory on the vehicle seat 2. After engagement, the user needs to move the carrier 1 so that the leading edge 1E of the carrier 1 can abut against the seat back 22 of the vehicle seat 2, thereby ensuring that the carrier 1 is securely connected to the vehicle seat 2. During this process, the movable support 10 needs to be able to move backward toward the carrier 1 so that the anchor joint 20 is adjacent to the carrier 1. However, at this time, the user needs to constantly operate the adjustment execution member 160 to have the adjustment execution member 160 drive the movable positioning member 120 to hold it in the disengaged position, which is very inconvenient.

[0132] 36 , in order to make it easier for the user to retract the movable support 10 without operating the adjustment execution member 160, a positioning post inclined surface 124 is provided at the end of the positioning post 120 that engages with one of the positioning holes 110. The positioning post inclined surface 124 is configured so that when a force that moves the movable support 10 toward the carrier 1 is applied, the edge of the positioning hole 110 engaged with the positioning post 120 abuts against the positioning post inclined surface 124, thereby pushing the positioning post 120 toward the disengagement position until the positioning post 120 is disengaged from the positioning hole 110, thereby allowing the movable support 10 to move relative to the carrier 1. That is, the positioning post inclined surface 124 is configured to face the edge of the positioning hole 110 that is closer to the anchor joint 20. As a result, when the anchor joint 20 is subjected to an acting force in a direction toward the carrier 1 (for example, the acting force is such that when the carrier 1 is pushed toward the vehicle seat 2, the anchor joint 20 is subjected to an opposite thrust of the corresponding accessory on the vehicle seat 2), the anchor joint 20 moves the movable support 10 toward the carrier 1, and thus the edge of the positioning hole 110 on the movable support 10 applies an abutment force to the positioning post inclined surface 124, thereby pushing the positioning post 120 to move toward the disengaged position.

[0133] It should be understood that the present disclosure is not limited thereto, and in all embodiments of the present disclosure, the positioning member clamp end 126 of the movable positioning member 120, which engages with one of the distance positioning members 110, is provided with a positioning member inclined surface 126A. Moreover, the positioning member inclined surface 126A may be installed in the same manner as the positioning post inclined surface 124 described above. For example, in the embodiment shown in FIG. 66B , the movable positioning member 120 is a positioning hook pivotally arranged on the carrier 1, and the distance positioning member 110 is a positioning hole arranged on the movable support 10. Here, the positioning member clamp end 126 of the positioning hook 120, which engages with one of the positioning holes 110, is provided with a positioning member inclined surface 126A. When the positioning member inclined surface 126A is subjected to an acting force that moves the movable support 10 toward the carrier 1, the edge of the positioning hole 110 engaged with the positioning member clamp end 126 abuts against the positioning member inclined surface 126A, thereby pushing the positioning hook 120 to pivot toward the disengaged position until the positioning hook 120 is disengaged from the positioning hole 110. In this way, the movable support 10 may be set so as to be movable relative to the carrier 1.

[0134] Furthermore, when the movable supports 10 receive an acting force directed toward the carrier 1, they may move toward the carrier 1. In the process of connecting the carrier 1 to the vehicle seat 2, the movable supports 10 and the anchor joints 20 connected thereto are likely to receive an acting force directed toward the carrier 1 by coming into contact with the vehicle seat 2, and therefore the movable supports 10 may accidentally move backward relative to the carrier 1, which is detrimental to the installation of the carrier 1. To avoid this problem, in one embodiment, as shown in FIGS. 34 and 40 to 42, each of the movable supports 10 may be provided with a support insertion hole 13 (see FIGS. 34 and 40), and the carrier 1 is provided with a support insertion member 104 for insertion into the support insertion hole 13. When the support insertion member 104 is movably inserted into the support insertion hole 13, the movable supports 10 cannot move relative to the carrier 1, thereby preventing the movable supports 10 from unintentionally moving backward or extending relative to the carrier 1.

[0135] In one embodiment, the support insertion hole 13 and the support insertion member 104 are arranged so that the support insertion member 104 can be inserted into the support insertion hole 13 only when the corresponding movable support 10 is moved to a point where the distance of the anchor joint 20 relative to the carrier 1 is at its maximum. Here, the movable support 10 is moved so that the distance of the anchor joint 20 relative to the carrier 1 is at its maximum, which means that the movable support 10 is extended to the greatest extent relative to the carrier 1, which makes it easy for the user to engage the anchor joint 20 with a corresponding accessory on the vehicle seat 2. The user can then adjust the movable support 10 to an appropriate extension length.

[0136] In this embodiment, the support insert 104 may be installed so as to be pivotally attached to the carrier 1 (see FIGS. 34, 40, and 42), or may be pivotally attached inside the insert housing 104B (see FIGS. 41 and 42), and the insert housing 104B may be fixed to the carrier 1. This allows the support insert 104 to be movably inserted into the support insertion hole 13 by a pivoting movement. However, the present disclosure is not limited thereto, and the support insert 104 may be installed so as to be translationally inserted into the support insertion hole 13.

[0137] In order to keep the support insert member 104 inserted in the support insert hole 13 without it being accidentally removed, in one embodiment, as shown in Figures 34 and 40, the carrier 1 or the insert member housing 104B may be provided with an insert member return elastic member 104A, which is installed to bias the support insert member 104 in the direction of insertion into the support insert hole 13. The insert member return elastic member 104A can be an appropriate elastic member such as a torsion spring, a spring, or a hydraulic rod.

[0138] On the other hand, after the anchor joint 20 is engaged with the corresponding accessory on the vehicle seat 2, the user needs to allow the movable support 10 to move backward relative to the carrier 1, and at this time, the user needs to remove the support insertion member 104 inserted into the support insertion hole 13 from the support insertion hole 13. Naturally, the user can manually operate the support insertion member 104 to remove it from the support insertion hole 13.

[0139] In one embodiment, as shown in Figures 34 and 42, the unlocking drive member 30 (the structure and operating principle of the unlocking drive member 30 are similar to those of the unlocking drive member 30 in the embodiment shown in Figures 12 to 21) arranged on each of the movable supports 10 is provided with a protrusion 33. When the unlocking drive member 30 is in the non-driving position, the protrusion 33 is not exposed from the support insertion hole 13, and when the unlocking drive member 30 is not in the non-driving position, the protrusion 33 is exposed from the support insertion hole 13 and drives the support insertion member 104 to detach from the support insertion hole 13. In this way, the support insertion member 104 is installed so as not to prevent the movable support 10 from moving relative to the carrier 1.

[0140] Specifically, on the one hand, when a user intends to engage the anchor joint 20 with a corresponding accessory on the vehicle seat 2, the movable support 10 can be moved to maximize the distance of the anchor joint 20 relative to the carrier 1, thereby allowing the support insertion member 104 to be inserted into the support insertion hole 13. As a result, the movable support 10 is held in that position relative to the carrier 1. During this process, the anchor joint 20 is in an unlocked state, and the unlock drive member 30 is in a non-driving position. At this time, the protrusion 33 of the unlock drive member 30 is not exposed from the support insertion hole 13, so that the support insertion member 104 remains inserted into the support insertion hole 13, thereby preventing the movable support 10 from moving backward relative to the carrier 1.

[0141] On the other hand, after the anchor joint 20 engages with the corresponding accessory on the vehicle seat 2, the anchor joint 20 is in a locked state, and the unlocking drive member 30 moves to a position other than the non-driven position. At this time, the protrusion 33 of the unlocking drive member 30 is exposed from the support member insertion hole 13 and drives the support member insertion member 104 to disengage from the support member insertion hole 13, so that the support member insertion member 104 does not hinder the movable support member 10 from moving relative to the carrier 1. Therefore, the movable support member 10 can move backward relative to the carrier 1, which makes it easier for the user to abut the front edge 1E of the carrier 1 against the seat back 22 of the vehicle seat 2.

[0142] It should be understood that the above-described engagement structure between the support insert member 104 and the support insert hole 13 can be applied to all embodiments of the adjustment device according to the present disclosure. In particular, when a slope similar to the positioning pillar slope 124 is provided at the top end of the movable positioning member 120 in this embodiment of the adjustment device, the above-described engagement structure between the support insert member 104 and the support insert hole 13 can be used to prevent the movable support 10 from unintentionally moving backward or extending relative to the carrier 1. On the other hand, even if a slope similar to the positioning pillar slope 124 is not provided at the top end of the movable positioning member 120, the above-described engagement structure between the support insert member 104 and the support insert hole 13 can be used as a second safety lock in addition to the first safety lock (i.e., the engagement structure between the movable positioning member 120 and the distance positioning member 110).

[0143] It should also be understood that the positions of the support insert member 104 and the support insert hole 13 can be arranged according to actual needs.

[0144] For example, in the embodiments shown in Figures 34, 35 and 40 to 42, the support body insertion holes 13 are arranged on opposing inner side walls of the two movable supports 10. Naturally, the support body insertion hole 13 may be provided on only the inner side wall or the outer side wall of one of the movable supports 10. Therefore, the support body insertion member 104 can be arranged adjacent to the inner side wall or the outer side wall of the movable support 10 so as to be inserted into the support body insertion hole 13. In addition, the protrusion 33 is arranged on the corresponding inner side or outer side of the unlocking drive member 30.

[0145] 66A and 66B, the support insertion hole 13 is arranged in the upper wall of the movable support 10. Naturally, the support insertion hole 13 may also be arranged in the lower wall of the movable support 10. Therefore, the support insertion member 104 may be arranged adjacent to the upper wall or lower wall of the movable support 10 so as to be inserted into the support insertion hole 13. In addition, the protrusion 33 is arranged on the corresponding upper or lower surface of the unlocking drive member 30.

[0146] Second embodiment of the unlocking mechanism for the anchor assembly

[0147] Figures 31 to 39 further show a second embodiment of the unlocking mechanism for the anchor assembly according to the present disclosure, and the main difference from the embodiment of the unlocking mechanism for the anchor assembly described above with reference to Figures 12 to 21 is that in the second embodiment, an unlocking execution member 130' is used instead of the unlocking operation member 40, and the drive structure and drive method of the unlocking drive member 30 are changed accordingly.

[0148] Specifically, in the second embodiment, the anchor assembly may include an unlocking execution member 130′ that is movably disposed on the carrier 1 and is configured to directly or indirectly drive the unlocking drive member 30 to slide toward the non-driven position.

[0149] In the embodiment shown in Figures 31 to 39, the unlocking execution member 130' is the same as the adjustment operation member 130 described above in terms of its structure and positional relationship with the carrier 1, and the only difference is that the function of the adjustment operation member 130 described above is to drive the positioning hook 120 to move it toward the disengaged position, while the function of the unlocking execution member 130' in the second embodiment is to drive the unlocking drive member 30 to slide it toward the non-driven position.

[0150] In the second embodiment, the anchor assembly may include an interlocking member 140. A first end 141 of the interlocking member 140 is connected to the unlocking execution member 130′, and a second end 142 of the interlocking member 140 is connected directly or indirectly to the unlocking drive member 30, so that the unlocking execution member 130′ drives the unlocking drive member 30 via the interlocking member 140.

[0151] In the second embodiment, as shown in FIG. 33 , in order to drive the unlocking drive member 30 to slide toward the non-driven position, the unlocking drive member 30 is provided with a plurality of oblique teeth 32. Correspondingly, the anchor assembly includes an oblique tooth engagement member 61 movably arranged on a fixed seat 60. The fixed seat 60 is fixed to the carrier 1. The oblique tooth engagement member 61 is arranged so that it can move when driven by the interlocking member 140 and abut against the slant surface of one of the plurality of oblique teeth 32, thereby pushing the unlocking drive member 30 to slide toward the non-driven position. It should be understood that the oblique tooth engagement member 61 can also be movably arranged on the carrier 1 without using the fixed seat 60.

[0152] To allow the oblique-tooth engagement member 61 disposed on the fixed seat 60 to move, as shown in FIGS. 37 and 39 , the fixed seat 60 is provided with an engagement member guide portion 602 through which the oblique-tooth engagement member 61 moves inside. Naturally, the present disclosure is not limited to this. The fixed seat 60 may be provided with other structures for guiding the movement of the oblique-tooth engagement member 61. For example, a pin shaft may be provided on either the fixed seat 60 or the oblique-tooth engagement member 61, and a sliding groove in which the pin shaft can slide may be provided on the other. The movement of the oblique-tooth engagement member 61 can be guided by engagement between the pin shaft and the sliding groove.

[0153] 34 and 36, the unlocking drive member 30 is located inside the movable support 10, and therefore the oblique tooth engagement member 61 can move to pass through the positioning hole 110 in the movable support 10 and abut against the oblique teeth 32 in the unlocking drive member 30. In an embodiment in which the positioning hole 110 is not provided in the movable support 10, the movable support 10 may be provided with a dedicated through-hole (not shown) through which the oblique tooth engagement member 61 moves and passes, or the movable support 10 may be arranged to expose a portion of the unlocking drive member 30 having the oblique teeth 32 so that the oblique tooth engagement member 61 can abut against the oblique teeth 32 of the unlocking drive member 30.

[0154] In the embodiments shown in Figures 31, 33, 34, and 36 to 39, the same fixing seat 60 is used to position the diagonal tooth engagement member 61 and the positioning post 120, which is convenient for manufacturing and assembling the members. However, the present disclosure is not limited thereto, and different fixing seats may be used to separately install the diagonal tooth engagement member 61 and the positioning post 120, respectively. Also, the diagonal tooth engagement member 61 can be movably positioned on the carrier 1 without using the fixing seat 60.

[0155] To drive the diagonal tooth engagement member 61, as shown in FIGS. 33, 38, and 39, in the second embodiment, the anchor assembly further includes an engagement member turntable 62 that can drive the diagonal tooth engagement member 61. The engagement member turntable 62 is rotatably installed on the fixed seat 60. The interlocking member 140 can directly or indirectly drive the engagement member turntable 62 to rotate in the third rotation direction R3 (see FIG. 33), thereby moving the diagonal tooth engagement member 61 in the direction of abutting against the diagonal teeth 32.

[0156] 37, a turntable torsion spring 622 is provided on the turntable rotation shaft 621 of the engagement member turntable 62. The turntable torsion spring 622 biases the engagement member turntable 62 in a direction to rotate it in a fourth rotation direction R4 opposite to the third rotation direction R3 (see FIGS. 33 and 38), thereby moving the inclined tooth engagement member 61 in a direction away from the inclined teeth 32.

[0157] After the unlocking drive member 30 moves to the non-driving position and the anchor joint 20 is unlocked, the user no longer operates the unlocking execution member 130', and therefore the turntable torsion spring 622 drives the engagement member turntable 62 to rotate toward the fourth rotation direction R4, thereby driving the oblique tooth engagement member 61 to move toward the direction away from the oblique teeth 32 until it leaves the positioning hole 110, so as to prevent the oblique tooth engagement member 61 from being inserted into the positioning hole 110 and hindering the movable support 10 from moving relative to the carrier 1.

[0158] 38 and 39, in order to enable the engagement member turntable 62 to drive the oblique tooth engagement member 61, the engagement member turntable 61 is provided with an engagement member drive hole 611 (see FIG. 39), the engagement member turntable 62 is provided with a turntable drive hole 623, and the turntable drive pin 624 passes through the engagement member drive hole 611 in the oblique tooth engagement member 61 and the turntable drive hole 623 in the engagement member turntable 62, so that the engagement member turntable 62 can drive the oblique tooth engagement member 61. Here, the turntable drive hole 623 may be designed to be larger in size so that the turntable drive pin 624 has sufficient movement space when the engagement member turntable 62 drives the oblique tooth engagement member 61.

[0159] 37 and 39, the engaging member guide portion 602 of the fixed seat 60 has an elongated engaging member guide portion slot 602A through which the rotating member drive pin 624 passes and moves. Naturally, the present disclosure is not limited thereto, and the engaging member rotating member 62 may have other structures and may drive the diagonal tooth engaging member 61 in other ways. For example, the engaging member rotating member 62 may be connected via a steel wire to drive and move the diagonal tooth engaging member 61.

[0160] 31 , the anchor assembly may further include an entraining member 150 connected to the second end 142 of the interlocking member 140. The entraining member 150 is movably disposed on the carrier 1, and is connected to the engaging member turntable 62 via the turntable connecting member 63. The entraining member 150 and the turntable connecting member 63 are installed so as to be able to transmit the drive of the interlocking member 140 to the engaging member turntable 62.

[0161] It should be understood that the entraining member 150 used in the second embodiment may be the same as the entraining member 150 described above with reference to Figures 7, 8, 23B, and 25B in terms of structure and operating principle related to driving the connecting post 200. That is, the entraining member 150 and the connecting post 200 used in the second embodiment may be similarly installed to drive and move relative to each other, so that the connecting post 200 can be driven by the unlocking execution member 130'.

[0162] As shown in Figures 33 and 34, the turntable connection member 63 may be connected to a turntable connection point 625 on the engagement member turntable 62, thereby allowing the turntable connection member 63 to drive and rotate the engagement member turntable 62 in a third rotation direction R3 (see Figure 33).

[0163] 38 and 39, the engagement member turntable 62 is approximately semi-circular in order to reduce the manufacturing materials and costs of the engagement member turntable 62 and at the same time reduce the weight of the engagement member turntable 62. However, the engagement member turntable 62 may also be completely circular in shape.

[0164] It should be understood that the second embodiment of the carrier adjustment device and the second embodiment of the anchor assembly unlocking mechanism described above can be used together as shown in Figures 31 to 36, but they can also be used independently.

[0165] Third embodiment of carrier adjustment device

[0166] 43 to 46 show a third embodiment of a carrier adjustment device according to the present disclosure, and the main difference from the embodiments of the adjustment device described above with reference to FIGS. 7 to 9 is that in the third embodiment, an anchor assembly operating member 40′ is used instead of the adjustment operating member 130, and correspondingly, in the third embodiment, the drive method of the movable positioning member 120 is changed.

[0167] Specifically, in the third embodiment, the anchor assembly may include a drive wheel 70 and an anchor assembly operating member 40'.

[0168] The drive wheel 70 is rotatably disposed on the movable support 10 and is installed so that the movable support 10 can move relative to the carrier 1 or the anchor joint 20 is unlocked.

[0169] The anchor assembly operating member 40' is installed so as to directly or indirectly drive and rotate the drive turntable 70. In addition, in the embodiment shown in Figures 43, 47, and 49, the anchor assembly operating member 40' is arranged near the crossbar 11 between the two movable supports 10, and the crossbar 11 may be installed below the movable supports 10 so as to be exposed from the bottom of the carrier 1, thereby allowing a user to easily touch and operate the anchor assembly operating member 40' arranged near the crossbar 11. Naturally, the present disclosure is not limited thereto, and the anchor assembly operating member 40' may be arranged in another position as long as it is convenient for a user to operate it.

[0170] 43, anchor assembly operating member 40' can be connected to and driven by drive turntable 70 via transmission member 50. However, the present disclosure is not limited thereto, and transmission member 50 may be omitted, and anchor assembly operating member 40' may be directly connected to and driven by drive turntable 70.

[0171] As shown in FIG. 43, the central portion 51 of the transmission member 50 is pivotally attached to the movable support 10. A first end 52 of the member 50 is connected to the anchor assembly operating member 40' and a second end 53 of the transmission member is connected directly or indirectly to the drive wheel 70.

[0172] In the embodiment shown in FIG. 43 , the latch 54 passes through the second end 53 of the transmission member 50, the arc-shaped slot 12 of the movable support 10, and the elongated slot 71 of the drive turntable 70 (see FIGS. 48 and 50 ), so that the second end 53 of the transmission member 50 is connected to and drives the drive turntable 70 via the latch 54. To facilitate the pivoting of the second end 53 of the transmission member 50 in the first rotation direction R1 or the second rotation direction R2, the slot 12 in the movable support 10 is configured as an arc-shaped slot so that the latch 54 can slide within the slot 12. In another embodiment, the latch 54 may be integrally formed with the second end 53 of the transmission member 50, so that the second end 53 of the transmission member 50 is directly connected to and drives the drive turntable 70.

[0173] The first end 52 and the second end 53 of the transmission member 50 are rotatable about a rotational connection in the central portion 51 .

[0174] When a user applies a force to anchor assembly operating member 40' in second rotational direction R2, first end 52 of transmission member 50 connected to anchor assembly operating member 40' pivots in second rotational direction R2 following the movement of anchor assembly operating member 40' (see FIG. 46), and accordingly, second end 53 of transmission member 50 connected to drive turntable 70 also pivots in second rotational direction R2. As a result, second end 53 drives drive turntable 70 to rotate in fifth rotational direction R5 (see FIG. 46).

[0175] When a user applies a force to anchor assembly operating member 40' in first rotational direction R1, first end 52 of transmission member 50 connected to anchor assembly operating member 40' pivots in first rotational direction R1 following the movement of anchor assembly operating member 40' (see FIG. 50), and accordingly, second end 53 of transmission member 50 connected to drive turntable 70 also pivots in first rotational direction R1. As a result, second end 53 drives drive turntable 70 to rotate in sixth rotational direction R6 (see FIG. 50).

[0176] Therefore, when a user operates anchor assembly operating member 40 ′, the movement of anchor assembly operating member 40 ′ is transmitted to drive wheel 70 via transmission member 50 .

[0177] To enable the drive wheel 70 to move the movable support 10 relative to the carrier 1, the anchor assembly includes at least two distance positioning members 110 arranged on the movable support 10, and a movable positioning member 120 arranged on the carrier 1 and movable between an engaged position and a disengaged position, where the movable positioning member 120 engages with one of the distance positioning members 110 at the engaged position and disengages from the distance positioning member 110 at the disengaged position.

[0178] 45 and 46, the movable positioning member 120 is a positioning hook pivotally arranged on the carrier 1, and the distance positioning member 110 is at least two positioning holes arranged on the movable support 10. It should be understood that the present disclosure is not limited thereto, and the movable positioning member 120 and the distance positioning member 110 may be, for example, two members that engage with each other by a recess and a groove, or a pin shaft, a slot, or the like.

[0179] 45 and 46, the anchor assembly further includes a first drive connection member 81. The first drive connection member 81 is connected between the drive turntable 70 and the movable positioning member 120, so that when the drive turntable 70 is rotated in the fifth rotation direction R5 by being driven by the anchor assembly operating member 40′ (see FIG. 46), the drive turntable 70 drives the positioning hook 120 via the first drive connection member 81 to move toward the disengaged position, thereby allowing the movable support 10 to move relative to the carrier 1.

[0180] Third embodiment of the unlocking mechanism for the anchor assembly

[0181] Figures 47 to 50 show a third embodiment of the unlocking mechanism for an anchor assembly according to the present disclosure, and the main difference from the embodiments of the unlocking mechanism for an anchor assembly described above with reference to Figures 12 to 21 is that in the third embodiment, a turntable 70 and a second drive connection member 82 are used instead of the unlocking drive member 30.

[0182] To enable the driving turntable 70 to unlock the anchor joint 20, the anchor assembly includes a sliding member 22. The sliding member 22 is disposed within the anchor joint 20 so as to be slidable between a driving position and a non-driving position, and is further configured such that when the sliding member 22 slides to the driving position, the anchor joint 20 can be maintained in a locked state, and when the sliding member 22 slides to the non-driving position, the anchor joint 20 can be unlocked. It should be understood that the sliding member 22 and anchor joint 20 used in the third embodiment may have the same structure and operating principle as the sliding member 22 and anchor joint 20 described above with reference to Figures 15 to 21.

[0183] 48 and 50 , the anchor assembly further includes a second drive connection member 82. The second drive connection member 82 is connected between the drive turntable 70 and the sliding member 22, and when the drive turntable 70 rotates in a sixth rotation direction R6 opposite to the fifth rotation direction R5, the drive turntable 70 drives the sliding member 22 via the second drive connection member 82 to slide toward the non-driven position (see FIG. 50 ), thereby unlocking the anchor joint 20.

[0184] The first drive connection member 81 and the second drive connection member 82 may both be flexible members made of various materials such as silk thread, string, rope, etc., or may be rigid members in the shape of a rod, plate, or block.

[0185] It should be understood that the third embodiment of the carrier adjustment device and the third embodiment of the anchor assembly unlocking mechanism described above can be used together as shown in Figures 45 and 46, or can be used separately.

[0186] When the third embodiment of the carrier adjustment device and the third embodiment of the anchor assembly unlocking mechanism are used in combination, and the first drive connection member 81 and the second drive connection member 82 are flexible members, in one embodiment, the first drive connection member 81 and the second drive connection member 82 may be two parts of the same drive connection member. That is, the first drive connection member 81 and the second drive connection member 82 may be, for example, the same steel wire, and the central part of the steel wire is connected to the turntable connection point 72 on the drive turntable 70 (see FIGS. 45, 46, 48, and 50; the first drive connection member 81 is not shown in FIGS. 48 and 50 for simplicity). In fact, the third embodiment selectively realizes movement of the movable support 10 relative to the carrier 1 and unlocking of the anchor joint 20 by using the anchor assembly operating member 40′, the drive turntable 70, and the drive connection members.

[0187] Fourth embodiment of carrier adjustment device and anchor assembly unlocking mechanism

[0188] Figures 51 to 62 show a fourth embodiment of a carrier adjustment device and anchor assembly unlocking mechanism according to the present disclosure, and the main difference from the adjustment device embodiment described above with reference to Figures 7 to 9 and the anchor assembly unlocking mechanism embodiment described above with reference to Figures 12 to 21 is that in the fourth embodiment, the movement of the movable support 10 relative to the carrier 1 and the unlocking of the anchor joint 20 are achieved using an anchor assembly operating member 40' and a functional drive member 90.

[0189] Specifically, in the fourth embodiment, the anchor assembly can include a functional drive member 90 and an anchor assembly operating member 40'.

[0190] 53, 55, 57, and 61, the function driving member 90 is movably disposed on the movable support 10, and is provided with a guide groove 91 consisting of a parallel groove 91A and an inclined groove 91B that communicate with each other. Here, the extension direction of the parallel groove 91A is parallel to the movement direction of the movable support 10, and the extension direction of the inclined groove 91B is inclined with respect to the movement direction of the movable support 10. The parallel groove 91A and the inclined groove 91B have an intersection 911, the parallel groove 91A has a parallel groove end 912 that is away from the intersection 911, and the inclined groove 91B has an inclined groove end 913 that is away from the intersection 911.

[0191] Correspondingly, the movable support 10 is provided with a guide post 14 that passes through the guide groove 91 .

[0192] By engaging the guide groove 91 with the guide column 14, the functional driving member 90 can be parallel to the movement direction of the movable support 10 and move relative to the movable support 10 to unlock the anchor joint 20, or can be inclined relative to the movement direction of the movable support 10 and move relative to the movable support 10 to move the movable support 10 relative to the carrier 1.

[0193] More specifically, to unlock the anchor joint 20, when the function drive member 90 moves and the guide column 14 is positioned at the parallel groove end 912, as shown in FIG. 55 , the function drive member 90 moves to the non-driving position, and via the unlock link rod 27 connected between the function drive member 90 and the sliding member 22, the function drive member 90 drives the sliding member 22 to move to the non-driving position, thereby unlocking the anchor joint 20. It should be understood that the sliding member 22 and anchor joint 20 used in the fourth embodiment may have the same structure and operating principle as the sliding member 22 and anchor joint 20 described above with reference to FIGS. 15 to 21. In other embodiments, the function drive member 90 may be connected to and driven by another member, or may be directly connected to and driven by the sliding member 22.

[0194] In the embodiment shown in FIG. 62, the unlocking link rod 27 has a main body 271 and two connecting arms 272 extending from the main body 271. Here, the main body 271 is provided with a main body connecting hole 271A for connecting with the function driving member 90. The two connecting arms 272 are used for connecting with the sliding member 22. Naturally, the unlocking link rod 27 can adopt any other appropriate structure.

[0195] On the other hand, in order to realize movement and positioning of the movable support 10 relative to the carrier 1, as shown in Figures 59 and 60, the anchor assembly includes at least two distance positioning members 110 arranged on the movable support 10 and a movable positioning member 120 arranged on the carrier 1 and movable between an engaged position and a disengaged position. Here, when the movable positioning member 120 is in the engaged position, it is engaged with one of the distance positioning members 110, thereby preventing the movable support 10 from moving relative to the carrier 1, and when the movable positioning member 120 is in the disengaged position, it is disengaged from the distance positioning member 110, thereby allowing the movable support 10 to move relative to the carrier 1.

[0196] 59 and 60, the movable positioning member 120 is a positioning post movably disposed on the carrier 1, with a positioning member return elastic member 123 disposed below the positioning post. The positioning member return elastic member 123 is configured to drive the movable positioning member 120 to move toward the engagement position. However, the present disclosure is not limited thereto, and the movable positioning member 120 may have other structures.

[0197] Correspondingly, the functional drive member 90 is provided with at least two pressing protrusions 92, which are arranged so that when the functional drive member 90 moves until the guide column 14 is positioned at the inclined groove end 913, one of the pressing protrusions 92 can press the movable positioning member 120 into the disengaged position, as shown in FIG. 60.

[0198] That is, when the guide groove 91 and the guide column 14 move until the functional drive member 90 positions the guide column 14 at the inclined groove end 913, as shown in Figure 57, the functional drive member 90 moves in a direction substantially perpendicular to the movement direction of the movable support 10, i.e., the functional drive member 90 moves toward the downward direction in Figure 57, thereby causing one of the pressing protrusions 92 of the functional drive member 90 to contact the movable positioning member 120 and pressing the movable positioning member 120 into the disengaged position.

[0199] In one embodiment, the number and positions of the pressing protrusions 92 of the functional driving member 90 may be set to correspond to the number and positions of the distance positioning members 110, so that when the functional driving member 90 moves the guide post 14 to be positioned at the inclined groove end 913, the pressing protrusions 92 can enter the distance positioning members 110 one by one, thereby ensuring that the movable positioning member 120 is pressed to the disengaged position. Naturally, the number of the pressing protrusions 92 of the functional driving member 90 may be set to be less than the number of the distance positioning members 110.

[0200] 61, an elongated retraction groove 93 for connection to the unlocking link rod 27 is provided at the end of the function drive member 90, and the extending direction of the retraction groove 93 is parallel to the extending direction of the inclined groove 91B. The pin shaft can pass through the main body connecting hole 271A in the unlocking link rod 27 and the retraction groove 93 in the function drive member 90, thereby connecting the function drive member 90 to the unlocking link rod 27. As a result, when the function drive member 90 moves relative to the movable support body 10 in a moving direction inclined relative to the movable support body 10, it is not interfered with by the unlocking link rod 27.

[0201] The anchor assembly operating member 40′ employed in the fourth embodiment has the same structure and operating principle as the anchor assembly operating member 40′ employed in the third embodiment, except that the anchor assembly operating member 40′ in the fourth embodiment is installed to directly or indirectly drive the functional drive member 90 to move it on the movable support 10.

[0202] Similar to the third embodiment, the anchor assembly operating member 40′ in the fourth embodiment can be connected to and driven by the functional drive member 90 via the transmission member 50. However, the present disclosure is not limited thereto, and the transmission member 50 may be omitted, and the anchor assembly operating member 40′ can be directly connected to and driven by the functional drive member 90.

[0203] As shown in FIG. 51, a central portion 51 of the transmission member 50 is pivotally attached to the movable support 10, a first end 52 of the transmission member 50 is connected to the anchor assembly operating member 40′, and a second end 53 of the transmission member is directly or indirectly connected to a functional drive member 90 (not shown in FIG. 51).

[0204] In the embodiment shown in FIG. 51 , the latch 54 passes through the second end 53 of the transmission member 50, the arc-shaped slot 12 of the movable support 10, and the elongated functional drive member connecting hole 94 of the functional drive member 90 (see FIGS. 53 , 55 , 57 , and 61 ), so that the second end 53 of the transmission member 50 is connected to and drives the functional drive member 90 via the latch 54. To facilitate the second end 53 of the transmission member 50 being pivoted in the first rotation direction R1 or the second rotation direction R2, the slot 12 in the movable support 10 is configured as an arc-shaped elongated groove so that the latch 54 can slide within the slot 12. In another embodiment, the latch 54 may be integrally formed with the second end 53 of the transmission member 50, so that the second end 53 of the transmission member 50 is directly connected to and drives the functional drive member 90.

[0205] The first end 52 and the second end 53 of the transmission member 50 are rotatable about the rotational connection of the central portion 51 .

[0206] When the user applies a force to the anchor assembly operating member 40' in the second rotational direction R2, the first end 52 of the transmission member 50 connected to the anchor assembly operating member 40' is pivoted in the second rotational direction R2 along with the anchor assembly operating member 40' (see Figure 55), and then the second end 53 of the transmission member 50 connected to the functional drive member 90 is also pivoted in the second rotational direction R2, whereby the second end 53 drives and moves the functional drive member 90 until the guide post 14 is positioned at the parallel groove end 912 (see Figure 55), thereby unlocking the anchor joint 20.

[0207] When the user applies a force to the anchor assembly operating member 40' in the first rotational direction R1, the first end 52 of the transmission member 50 connected to the anchor assembly operating member 40' is pivoted in the first rotational direction R1 along with the anchor assembly operating member 40' (see Figure 57), and then the second end 53 of the transmission member 50 connected to the functional drive member 90 is also pivoted in the first rotational direction R1, thereby causing the second end 53 to drive the functional drive member 90 until the guide post 14 is positioned at the inclined groove end 913 (see Figure 57), thereby realizing movement of the movable support 10 relative to the carrier 1.

[0208] Fifth embodiment of carrier adjustment device

[0209] Figures 63 to 71 show a fifth embodiment of a carrier adjustment device according to the present disclosure, and the main difference from the embodiments of the adjustment device described above with reference to Figures 7 to 9 is that in the fifth embodiment, an adjustment execution member 180 is used instead of the adjustment operation member 130, and correspondingly, in the fifth embodiment, the connecting member between the adjustment execution member 180 and the movable positioning member 120 is omitted.

[0210] Specifically, the fifth embodiment of the adjusting device 100 may include an adjustment execution member 180. The adjustment execution member 180 is directly connected to or integrally formed with the movable positioning member 120, and is installed so as to drive the movable positioning member 120 to move toward the disengaged position. That is, since there is no other connecting member between the adjustment execution member 180 and the movable positioning member 120, the manufacturing and installation costs of the adjusting device 100 can be reduced.

[0211] In the embodiment shown in Figures 66A, 66B, 69 and 70, the movable positioning member 120 is disposed within the carrier 1, and the movable positioning member 120 has a positioning member connection portion 127 exposed outside the carrier 1 (see Figures 69 and 70), whereby the adjustment execution member 180 is connected to the positioning member connection portion 127 on the outside of the carrier 1, thereby allowing the user to easily drive the movable positioning member 120 within the carrier 1 by operating the adjustment execution member 180 outside the carrier 1.

[0212] In another embodiment, the movable positioning member 120 may not be provided with the positioning member connection portion 127, and instead the adjustment execution member 180 is provided with a portion that can be inserted into the carrier 1 and connected to the movable positioning member 120.

[0213] In yet another embodiment, the movable positioning member 120 can be integrally formed with the adjustment execution member 180, for example, the positioning member connection portion 127 of the movable positioning member 120 exposed to the outside of the carrier 1 can be used as the adjustment execution member 180.

[0214] Also, although the movable positioning member 120 is shown as a positioning hook pivotally disposed on the carrier 1, the movable positioning member 120 in this embodiment may take other forms, such as a positioning post.

[0215] Although the adjustment execution member 180 is shown in the form of a sliding cover, the adjustment execution member 180 may take various structural forms, such as a handle, a wrench, a lever, a button, or a knob. Furthermore, the movement of the adjustment execution member 180 on the carrier 1 may be performed in various forms, such as sliding, pivoting, or screw rotation, as long as it can drive the movable positioning member 120. For example, if the movable positioning member 120 is a positioning hook that is pivotally disposed on the carrier 1, the adjustment execution member 180 may be a knob that rotates coaxially with the positioning hook 120, and the knob may be installed so that, when operated to rotate by a user, it can move the positioning hook 120 and pivot it toward the disengaged position.

[0216] 68-70, the carrier 1 has an opening 105 (see FIG. 70) at the position where the movable positioning member 120 is provided, thereby exposing the movable positioning member 120 to the outside of the carrier 1 through the opening 105, thereby facilitating connection between the movable positioning member 120 and the adjustment execution member 180. The opening 105 may be sized to expose most of the movable positioning member 120, as shown in FIG. 70. The opening 105 may also be sized to expose only a small portion of the movable positioning member 120, for example, only the positioning member connection portion 127.

[0217] 68 and 69, in order to prevent dust and other foreign matter from entering the inside of the carrier 1 through the opening 105 and affecting the operation of the movable positioning member 120, and to improve the appearance of the carrier 1, the carrier 1 is provided with a decorative cover 106 that covers the opening 105. Naturally, if the size of the opening 105 is such that only the positioning member connection portion 127 of the movable positioning member 120 is exposed, there is no need to provide the decorative cover 106.

[0218] As shown in Figures 69 and 71, the decorative cover 106 is provided with a decorative cover long groove 106A that extends through the decorative cover long groove 106A, and the positioning member connecting portion 127 passes through the decorative cover long groove 106A, thereby being exposed to the outside of the carrier 1, and can slide along the decorative cover long groove 106A. The movement of the movable positioning member 120 between the engaged position and the disengaged position can be limited by the positioning member connecting portion 127 that slides along the decorative cover long groove 106A.

[0219] In addition, in order to prevent the movable positioning member 120 from swinging during movement, at least one of the carrier 1 and the decorative cover 106 can be provided with a support rib 107 for supporting the movable positioning member 120, as shown in Figures 70 and 71, thereby ensuring that the movement of the movable positioning member 120 is more stable.

[0220] 66B , the carrier 1 may further be provided with a positioning member return torsion spring 123, which is installed to drive the movable positioning member 120 to move toward the engagement position. Therefore, when the user does not operate the adjustment execution member 180, the movable positioning member 120 is driven by the positioning member return torsion spring 123 to move to the engagement position and engage with one of the distance positioning members 110.

[0221] 71, the decorative cover 106 is provided with a torsion spring column 106B on which a positioning member return torsion spring 123 is disposed. Of course, the positioning member return torsion spring 123 may be a resilient member employing another structure such as a spring or hydraulic rod that drives the movable positioning member 120 to move toward the engaged position.

[0222] 67, when two movable positioning members 120 are provided and the two movable positioning members 120 engage with two movable supports 10, respectively, a positioning member linking rod 128 may be connected between the two movable positioning members 120. The positioning member linking rod 128 is installed so that one movable positioning member 120 can synchronously move the other movable positioning member 120 via the positioning member linking rod 128. This allows the user to synchronously move the two movable positioning members 120 simply by driving one of the movable positioning members 120.

[0223] As shown in FIGS. 63, 64, and 68-70, to facilitate the operation of the movable positioning member 120, the adjustment execution member 180 is disposed on the outer surface of the support seat 1D below the side 1C of the carrier 1, allowing for easy operation by the user. In one embodiment, two adjustment execution members 180 are disposed on the outer surfaces of the two support seats 1D on both sides of the carrier 1. Therefore, when a user operates the adjustment execution member 180 on either side of the carrier 1 to drive one of the movable positioning members 120, the positioning member linkage rod 128 connected between the two movable positioning members 120 allows the two movable positioning members 120 to move synchronously, which is convenient for the user. Naturally, the user can also operate the two adjustment execution members 180 on both sides of the carrier 1 with both hands. In yet another embodiment, only one adjustment execution member 180 is disposed on the outer surface of one support seat 1D on one side of the carrier 1, thereby reducing manufacturing and installation costs. Therefore, when a user operates one adjustment execution member 180 to drive a movable positioning member 120, the two movable positioning members 120 can move synchronously due to the positioning member linkage rod 128 connected between them.

[0224] Fifth embodiment of the unlocking mechanism for the anchor assembly

[0225] Figure 72 shows a fifth embodiment of the unlocking mechanism for an anchor assembly according to the present disclosure, and the main difference from the second embodiment of the unlocking mechanism for an anchor assembly described above with reference to Figures 31 to 39 is that the intermediate member between the unlocking execution member 130' and the unlocking drive member 30 in the fifth embodiment is significantly reduced, thereby reducing the manufacturing and installation costs of the unlocking mechanism for an anchor assembly.

[0226] Specifically, the structure of the unlocking execution member 130' in the fifth embodiment and its positional relationship with the carrier 1 are the same as those of the unlocking execution member 130' described in the second embodiment.

[0227] In one embodiment, only the interlocking member 140 is provided between the unlock execution member 130′ and the unlock drive member 30, i.e., the first end 141 of the interlocking member 140 is connected to the unlock execution member 130′, and the second end 142 is directly connected to the unlock drive member 30. When a user operates the unlock execution member 130′, the unlock execution member 130′ drives the unlock drive member 30 via the interlocking member 140 to slide toward the non-driven position.

[0228] In yet another embodiment, in order for the unlock execution member 130′ to move the unlock drive member 30 to the non-driving position to unlock the anchor joint 20 and simultaneously move the connecting post 200 to the retracted position to enable the carrier 1 to be detached from the carrier applying device, as shown in FIG. 72 , not only is an interlocking member 140 having a first end 141 connected to the unlock execution member 130′ provided between the unlock execution member 130′ and the unlock drive member 30, but also a driving member 150 connected to a second end 142 of the interlocking member 140 is provided. The driving member 150 is movably disposed on the carrier 1 and connected to the unlock drive member 30 via the driving member connecting member 64. The driving member 150 and the driving member connecting member 64 are arranged to be able to transmit the driving force of the interlocking member 140 to the unlock drive member 30. Therefore, when the user operates the unlocking execution member 130', the unlocking execution member 130' drives the unlocking drive member 30 to slide toward the non-driven position via the interlocking member 140, the driving member 150, and the drive member connecting member 64.

[0229] It should be understood that the entraining member 150 used in the fifth embodiment may be substantially the same as the entraining member 150 described above with reference to Figures 6, 7, 8, 23B and 25B in terms of the structure and operating principle related to driving the connecting post 200. That is, the entraining member 150 and the connecting post 200 used in the fifth embodiment may be installed to move in conjunction with each other so that the connecting post 200 can be driven by the unlocking execution member 130'.

[0230] Base for placing carriers

[0231] In order to facilitate the user to connect the carrier 1 to the vehicle seat 2 shown in FIG. 1, the present disclosure further provides another method, namely, as shown in FIG. 73, the carrier 1 is connected to the vehicle seat 2 by a base 400.

[0232] The base 400 according to the present disclosure may be pre-connected to the vehicle seat 2 by conventional means such as a seat belt or ISOFIX. Therefore, when the carrier 1 is connected to or separated from the base 400, i.e., when the carrier 1 is connected to or separated from the vehicle seat 2, this method can greatly improve the convenience of connecting or detaching the carrier 1 to or from the vehicle seat 2.

[0233] It should be understood that the base 400 of the present disclosure can be used not only to mount a carrier 1 that includes an anchor assembly, but also to position a carrier that does not include an anchor assembly.

[0234] As shown in FIGS. 75A, 75B, 76A, and 76B, when the base 400 is used to mount a carrier 1 including the anchor assembly as described above, a retraction space 480 is provided in the base 400. The retraction space 480 may be located inside the front side of the base 400 at a position corresponding to the anchor assembly of the carrier 1. For example, the retraction space 480 may be located between the two front side walls and two base protrusions 430 (described below) of the base 400. Therefore, when the carrier 1 is placed on the base 400, the retraction space 480 can accommodate the anchor assembly of the carrier 1. For example, the retraction space 480 may be a space formed between the two front side walls and two base protrusions 430 (described below) of the base 400 and the top surface of the base 400. To ensure that the width of the evacuation space 480 is sufficient to accommodate the anchor assembly, as shown in FIGS. 76A and 76B , recesses 482 may be formed in each of the side walls of the base 400 that form the evacuation space 480, and the recesses 482 may extend downward from the top of the side wall to the center of the side wall. Therefore, when the carrier 1 is placed on the base 400, the evacuation space 480 may accommodate the anchor assembly of the carrier 1. Before the carrier 1 is placed on the base 400, the anchor assembly may be adjusted to an appropriate extended length depending on the condition of the evacuation space 480; for example, the extended length may be adjusted to the shortest length.

[0235] Of course, if the base 400 is used to place a carrier that does not include an anchor assembly, the base 400 does not need to have the retreat space 480.

[0236] 73 to 82 show a first embodiment of a base 400 according to the present disclosure for placing a carrier 1 thereon. For convenience of explanation, as described above, as shown in FIGS. 73 to 77, the direction in which the backrest 1A of the carrier 1 faces is defined as "front," the direction in which the back faces is defined as "rear," and the left-right direction of the carrier 1 is defined as "lateral direction." It should be understood that positional terms such as "front," "rear," and "lateral direction" are used for clarity and convenience of explanation and do not limit the present disclosure.

[0237] 75A, 75B, 76A, and 76B, a base 400 according to the present disclosure includes a base engagement member 410 and a base operation member 420. Here, the base engagement member 410 is used to engage the carrier 1, and the base operation member 420 is used to drive the base engagement member 410.

[0238] First, the base engaging member 410 and its associated components will be described in detail below.

[0239] 75A, 76A, and 77 to 79, the base engagement member 410 on the base 400 is arranged to be movable between an engaged position and a disengaged position. Here, the base engagement member 410 can engage with the carrier engagement member 108 (see FIG. 74) arranged on the carrier 1 at the engaged position, thereby connecting the carrier 1 to the base 400 as shown in FIG. 73, and further, the base engagement member 410 can disengage from the carrier engagement member 108 at the disengaged position, thereby allowing the carrier 1 to move away from the base 400.

[0240] As shown in FIG. 77 , the base engagement member 410 can be moved to the disengaged position by the drive of the base operating member 420 and then returned to the engaged position by the base resilient member 450. The base resilient member 450 is configured to drive the base engagement member 410 to move toward the engaged position. In the embodiment shown in FIG. 77 , the base resilient member 450 is a torsion spring. However, the base resilient member 450 may take other forms, such as a compression spring or a hydraulic rod, as long as it can drive the base engagement member 410 to move toward the engaged position. It should also be understood that the base resilient member 450 is not required for the present disclosure, and the base engagement member 410 can be configured to return to the engaged position by the drive of the base operating member 420.

[0241] In order to make it easier for the user to move the base engagement member 410 to the disengagement position without operating the base operating member 420 during the process of placing the carrier 1 on the base 400, in the embodiment shown in FIGS. 75A to 77 , an engagement member slope 413 is provided on the end of the base engagement member 410 that engages with the carrier engagement member 108. The engagement member slope 413 is installed so that when the base engagement member 410 is ready to engage with the carrier engagement member 108, the carrier engagement member 108 can abut against the engagement member slope 413, thereby pushing the base engagement member 410 to move toward the disengagement position, which is more convenient for the user.

[0242] 74, in one embodiment, the carrier engagement member 108 may be a carrier engagement rod disposed on each of the support seats 1D of the carrier 1. The base engagement member 410 may be a base engagement hook (see FIGS. 75A to 77) pivotally provided on the base 400. By engaging the carrier engagement rod 108 with or disengaging it from the base engagement hook 410, the carrier 1 can be easily connected to or detached from the base 400.

[0243] In this embodiment, as shown in FIG. 77 , an engagement member slope 413 is provided on the end of a front base engagement hook 410A (described below) that engages with the carrier engagement rod 108. The engagement member slope 413 is inclined with respect to the horizontal direction so that when the front base engagement hook 410A is ready to engage with the carrier engagement rod 108, the carrier engagement rod 108 can abut against the engagement member slope 413, thereby generating a pivot moment in the front base engagement hook 410A and causing the front base engagement hook 410A to pivot along the seventh rotational direction R7 to a disengaged position. Correspondingly, as shown in FIG. 77 , an engagement member slope 413 can also be provided on the end of a rear base engagement hook 410B (described below) that engages with the carrier engagement rod 108. The engagement member slope 413 is inclined with respect to the horizontal direction so that when the rear base engagement hook 410B is ready to engage with the carrier engagement rod 108, the carrier engagement rod 108 can abut against the engagement member slope 413, thereby generating a pivot moment on the rear base engagement hook 410B and causing the rear base engagement hook 410B to pivot along an eighth rotational direction R8 to a disengagement position. Note that in this embodiment, the direction in which the front base engagement hook 410A pivots toward the disengagement position (i.e., the seventh rotational direction R7) is different from the direction in which the rear base engagement hook 410B pivots toward the disengagement position (i.e., the eighth rotational direction R8), and therefore the inclination direction of the engagement member slope 413 of the front base engagement hook 410A is also different from the inclination direction of the engagement member slope 413 of the rear base engagement hook 410B. However, when the front base engagement hook 410A and the rear base engagement hook 410B are arranged so that they pivot in the same direction toward the disengaged position, the inclined direction of the engagement member slope 413 of the front base engagement hook 410A may be arranged so that it is in the same direction as the inclined direction of the engagement member slope 413 of the rear base engagement hook 410B.

[0244] 74, the carrier engagement rod 108 is arranged to extend along a lateral direction perpendicular to the front-rear direction of the carrier 1. It should be understood that the carrier engagement rod 108 can also be arranged to extend along the front-rear direction of the carrier 1, and in such a case, the position of the base engagement hook 410 and the engagement direction with the carrier engagement rod 108 need to be adjusted accordingly.

[0245] 77, the base engagement hook 410 is pivotally mounted to the engagement hook fixing seat 411, which is fixed to the base 400. In other embodiments, the base engagement hook 410 may also be directly connected to the base 400. Also, the base engagement hook 410 is not limited to pivoting, but may also slide.

[0246] Of course, the present disclosure is not limited thereto. The carrier engagement member 108 and the base engagement member 410 according to the present disclosure may be other engagement members. For example, the carrier engagement member 108 may be an engagement hole provided in the carrier 1, and the base engagement member 410 may be an engagement pin movably inserted into the engagement hole.

[0247] 75A to 76B, in order to better position the carrier 1 within the base 400, the base 400 may be provided with base protrusions 430 on the surface that contacts the carrier 1, and each base protrusion 430 is provided with a base groove 431 that can accommodate the carrier engagement rod 108. Furthermore, the base engagement hook 410 is at least partially movably disposed within the base groove 431, and is configured to be able to lock the carrier engagement rod 108 within the base groove 431 when the base engagement hook 410 is in the engaged position, and to allow the carrier engagement rod 108 to move in and out of the base groove 431 when the base engagement member 410 is in the disengaged position.

[0248] In order to position the carrier 1 more stably within the base 400, multiple engagement points can be arranged between the carrier 1 and the base 400 to prevent the carrier 1 from falling over or rocking after the carrier 1 and the base 400 are connected.

[0249] In the embodiment shown in FIGS. 75A to 79, the base engagement member 410 may include a front base engagement member 410A and a rear base engagement member 410B spaced apart by a fixed distance along the front-to-rear direction of the base 400. Here, the front base engagement member 410A is located at the front of the base 400, and the rear base engagement member 410A is located at the rear of the base 400. Correspondingly, as shown in FIG. 74, the carrier engagement member 108 may include a front carrier engagement member 108A and a rear carrier engagement member 108B spaced apart by a fixed distance along the front-to-rear direction of the carrier 1. The positions of the front carrier engagement member 108A and the rear carrier engagement member 108B correspond to the positions of the front base engagement member 410A and the rear base engagement member 410B, respectively. This structure can prevent the carrier 1 from tipping over in the front-to-rear direction on the base 400.

[0250] Furthermore, two or more front base engagement members 410A and two or more rear base engagement members 410B are provided along the lateral direction of the carrier 1 (as shown in FIGS. 75A to 77). Such a structure can prevent the carrier 1 from swinging laterally on the base 400.

[0251] Next, the base operating member 420 and its related components will be described in detail.

[0252] In the base 400 according to the present disclosure, the base operating member 420 is movably disposed on the base 400 and is installed to directly or indirectly drive the base engaging member 410 to move toward the disengaged position.

[0253] 75A to 79, the base engagement member 410 includes a front base engagement member 410A and a rear base engagement member 410B, and the base operating member 420 may be installed to directly drive the rear base engagement member 410B to pivot in an eighth rotational direction R8 (i.e., to move toward the disengaged position), as shown in Fig. 77, and simultaneously indirectly drive the front base engagement member 410A to pivot in a seventh rotational direction R7 (i.e., to move toward the disengaged position) via the base interlocking member 440. In this embodiment, the seventh rotational direction R7 of the front base engagement member 410A and the eighth rotational direction R8 of the rear base engagement member 410B are opposite directions. However, it should be understood that the seventh rotational direction R7 of the front base engagement member 410A and the eighth rotational direction R8 of the rear base engagement member 410B may be set to be the same, for example, the rear base engagement member 410B may be set to pivot toward the seventh rotational direction R7 to a disengaged position.

[0254] The base interlocking member 440 may be a flexible member made of various materials such as string, wire, rope, etc., or may be a rigid member in the form of a rod, plate, or block. The base interlocking member 440 is for transmitting the movement of the base operating member 420 to the front base engaging member 410A.

[0255] More specifically, as shown in Figures 76A to 81, the base operating member 420 includes an operating member main body 421 configured to be able to operate the base 400 from the outside, and an operating member extension portion 422 extending from the operating member main body 421 toward the inside of the base 400 so as to be able to contact and drive the base engaging member 410.

[0256] 77, 80, and 81, the operating member main body 421 is provided with an operating member long groove 421A extending along the front-to-rear direction of the base 400, and the base 400 is provided with a base protrusion 460 (see FIGS. 80 and 81) that passes through the operating member long groove 421A, thereby allowing the base operating member 420 to move relative to the base 400. Furthermore, because the base protrusion 460 can only slide within the operating member long groove 421A, the position and movement stroke of the base operating member 420 relative to the base 400 are limited, thereby preventing the base operating member 420 from being accidentally detached from the base 400.

[0257] 77, 80, and 81, the operating member extension 422 is provided with an operating member position restricting groove 422B extending along the front-rear direction of the base 400, and the base 400 is provided with a base position restricting post 491 passing through the operating member position restricting groove 422B. Such a structure can also restrict movement of the base operating member 420 relative to the base 400. This structure can be used together with the above-described structure of the operating member long groove 421A and base protruding post 460, or can be used alone.

[0258] To make the movement of the base operating member 420 relative to the base 400 more stable, the base 400 may be provided with a U-shaped base position limiting rib 492, and the operating member extension 422 may be installed so as to pass through the base position limiting rib 492 and move along the base position limiting rib 492. Such a structure may be used together with the above-described structure of the operating member long groove 421A and the base protruding post 460, or the above-described structure of the operating member position limiting groove 422B and the base position limiting post 491, or may be used alone.

[0259] Additionally, the base operating member 420 can drive the base engaging member 410 in a variety of ways.

[0260] 77 and 78, the operating member extension portion 422 of the base operating member 420 is provided with an elongated operating member drive groove 422A, and the base engagement member 410 is provided with an engagement member drive pin 412 (see FIG. 78), which passes through the operating member drive groove 422A. Furthermore, the extension direction of the operating member drive groove 422A is inclined with respect to the movement direction of the base operating member 420, so that when the base operating member 420 moves relative to the base 400, the operating member drive groove 422A drives the engagement member drive pin 412 to slide therein, and the sliding direction of the engagement member drive pin 412 in the operating member drive groove 422A is also inclined with respect to the movement direction of the base operating member 420, so that the base engagement member 410 pivots or moves, thereby realizing the base engagement member 410 moving toward the disengaged position.

[0261] 77, when the base operating member 420 is operated and moved, its operating member extension 422 moves synchronously, and the operating member drive groove 422A of the operating member extension 422 drives the engagement member drive pin 412 (see FIG. 78) of the rear base engagement member 410B, causing the rear base engagement member 410B to pivot in the eighth rotational direction R8 (i.e., toward the disengaged position). At the same time, the base interlocking member 440 connected to the operating member extension 422 transmits the movement of the base operating member 420 to the front base engagement member 410A, causing the front base engagement member 410A to pivot in the seventh rotational direction R7 (i.e., toward the disengaged position).

[0262] Of course, the present disclosure is not limited in this respect, and the base manipulation member 420 may drive the base engagement member 410 in other ways. For example, in an embodiment in which the direction of movement of the base manipulation member 420 is the same as the direction of movement of the base engagement member 410 toward the disengaged position, the base manipulation member 420 may be fixed or integrally formed with the base engagement member 410, thereby achieving synchronous movement. Alternatively, an intermediate member similar to the base linkage member 440 may be disposed between the base manipulation member 420 and the base engagement member 410, which can transmit the movement of the base manipulation member 420 to the base engagement member 410. Alternatively, the manipulation member extension 422 of the base manipulation member 420 may extend not only to the rear base engagement member 410B but also to the front base engagement member 410A, so that the manipulation member extension 422 of the base manipulation member 420 can simultaneously drive the rear base engagement member 410B and the front base engagement member 410A to pivot in the same direction, thereby omitting the base linkage member 440.

[0263] To avoid the problem that the base operation member 420 is exposed to the outside, resulting in an unsightly appearance and easy damage to the internal components, the base 400 further includes a bottom cover 470, as shown in FIG. 82 , which is fixed to the base 400 and partially covers the base operation member 420. The bottom cover 470 partially covers the base operation member 420, not only protecting the internal components but also allowing the user to contact and operate the base operation member 420 from outside the base 400.

[0264] The base 400 according to the present disclosure for mounting the carrier 1 may also adopt another embodiment that differs from the previous embodiment in that the carrier engagement member of the carrier is movable between an engaged position and a disengaged position, while the base engagement member of the base is fixed relative to the base. Furthermore, in such another embodiment, the base operation member is replaced with a carrier operation member.

[0265] Specifically, the base 400 is provided with a base engagement member 410' (see the schematic structure shown in Figures 75B and 76B), and the carrier 1 includes a carrier engagement member 200 (see Figures 73 and 74). The carrier engagement member 200 is arranged on the carrier 1 so as to be movable between an engaged position and a disengaged position. Here, when the carrier engagement member 200 is in the engaged position, it engages with the base engagement member 410' of the base 400, and when it is in the disengaged position, it is disengaged from the base engagement member 410'.

[0266] The carrier 1 further includes a carrier operating member, for example, an adjustment operating member 130 shown in FIG. 74. The adjustment operating member 130 is movably disposed on the carrier 1 and is installed so as to directly or indirectly drive the carrier engagement member 200 to move it toward the disengagement position. A user operates the carrier operating member on the carrier 1 to drive the carrier engagement member, thereby realizing the movement of the carrier 1 away from the base 400.

[0267] In the embodiment shown in FIGS. 73 and 74 , the carrier engagement member 200 on the carrier 1 can employ the aforementioned connecting post 200 for connecting to the carrier applying device, and the carrier operation member can employ the aforementioned adjusting and operating member 130. In this embodiment, the base 400 can be used as the carrier applying device as described above, and the base engagement member 410′ is a base engagement hole that can engage with the connecting post 200, as shown in FIGS. 75B and 76B . Specifically, the connecting post 200 is disposed on the carrier 1 so as to be movable between an extended position and a retracted position. When the connecting post 200 is in the extended position, it can engage with the base engagement member 410′ on the base 400 so that the carrier 1 can be connected to the base 400. When the connecting post 200 is in the retracted position, it can disengage from the base engagement member 410′, thereby allowing the carrier 1 to be removed from the base 400. The adjusting and operating member 130 can drive the connecting post 200 to move toward the retracted position. As a result, if the carrier 1 is already provided with the connecting posts 200, it is only necessary to place the base engagement members 410' (e.g., the base engagement holes shown in Figures 75B and 76B) that can engage with the connecting posts 200 on the base 400, and the carrier 1 can easily be connected to or disconnected from the base 400 without providing any other members, thereby significantly reducing manufacturing and assembly costs.

[0268] In order to more stably position the carrier 1 on the base 400, a plurality of connecting posts 200 may be arranged on the carrier 1. For example, at least two connecting posts 200 spaced a certain distance apart in the front-rear direction may be arranged on each side of the carrier 1, and at least two base engagement holes 410' spaced a certain distance apart in the front-rear direction may be arranged on each side wall of the base 400. Therefore, engagement between the plurality of connecting posts 200 and the plurality of base engagement holes 410' can prevent the carrier 1 from tipping over in the front-rear direction relative to the base 400.

[0269] It should be understood that the connection structure and drive of the connecting post 200 and the adjusting / operating member 130 in this embodiment may be the same as or different from the connection structure and drive of the connecting post 200 and the adjusting / operating member 130 described above with reference to Figures 2A, 2B, 7, 9, 23B, and 25B. For example, the adjusting / operating member 130 in this embodiment may be connected to and driven by only one interlocking member 140 or by another intermediate member.

[0270] Of course, the present disclosure is not limited in this respect. The carrier engagement members of the carrier 1 may not employ connecting posts 200, and the carrier operation members may not employ adjustment operation members 130. In other embodiments, separate carrier engagement members and carrier operation members may be disposed on the carrier 1 to achieve engagement or disengagement between the carrier engagement members and the base engagement members 410′ of the base 400, thereby enabling the carrier 1 to be positioned or removed from the base 400.

[0271] In addition, when the connecting posts 200 of the carrier 1 are only used to connect another carrier application device and not the base 400, the side wall of the base 400 can be provided with connecting post retraction grooves 481 at positions corresponding to the connecting posts 200. As shown in Figures 75A to 76A, when the carrier 1 is placed on the base 400, the connecting post retraction grooves 481 are used to accommodate the connecting posts 200 of the carrier 1.

[0272] Figures 83 to 91 show a second embodiment of a base 400 for mounting a carrier 1 according to the present disclosure, and the main difference from the first embodiment of the base 400 described above with reference to Figures 73 to 82 is that in the first embodiment, the base operating member 420 is composed of a single member, and the user operates the single member to move it in parallel to drive the base engaging member 410, whereas in the second embodiment, the base operating member 420 is composed of multiple members, and the user operates one of the members to rotate it to drive the base engaging member 410.

[0273] Specifically, in the second embodiment of the base 400, the base operating member 420 includes an operating member rotating portion 423 and an operating member driving portion 424.

[0274] As shown in FIGS. 84 and 86, the operating member rotating portion 423 is rotatably connected to the base 400.

[0275] The operating member rotating portion 423 is installed so that it can be rotated by operating it from outside the base 400. The operating member rotating portion 423 may be in the form of a block, a plate, a rod, or any other specially designed structure.

[0276] In one embodiment, as shown in FIG. 84, the base operating member 420 may include an operating member rotation shaft 425, and the operating member rotating portion 423 can rotate around the operating member rotation shaft 425.

[0277] It should be understood that the operating member rotation shaft 425 may be formed integrally with the operating member rotation unit 423, or may be a separate member independent of the operating member rotation unit 423, and the base 400 may be formed with a shaft hole (not shown) through which the operating member rotation shaft 425 rotates. Alternatively, the operating member rotation shaft 425 may be formed integrally with the base 400, and the operating member rotation unit 423 may be formed with a shaft hole through which the operating member rotation shaft 425 rotates.

[0278] In another embodiment, the base operating member 420 may not include the operating member rotation axis 425, and instead, an arc-shaped guide rail (not shown) may be formed on the base 400, and the operating member rotation portion 423 may rotate along the arc-shaped guide rail.

[0279] Since the operating member rotating portion 423 rotates on the base 400, the base operating member 420 does not need to extend from the base 400 as in the first embodiment, which is advantageous in application environments where the operating space is small.

[0280] The operating member driving unit 424 is movably connected to the base 400 and can contact and drive the base engaging member 410. The rotation of the operating member rotating unit 423 directly or indirectly drives and moves the operating member driving unit 424, thereby driving the base engaging member 410.

[0281] It should be understood that the base engagement member 410 used in the second embodiment may have the same structure and operating principle as the base engagement member 410 described in the first embodiment. Therefore, as shown in Fig. 84, the operation member drive unit 424 in the second embodiment may have the same structure as the operation member extension unit 422 in the first embodiment.

[0282] For example, the operating member driver 424 may be provided with an elongated driver drive groove 424B (see FIG. 84 ). The driver drive groove 424B is similar to the operating member drive groove 422A in the first embodiment and is used to engage with the engagement member drive pin 412 (see FIG. 84 ) in the base engagement member 410. As a result, when the operating member driver 424 moves relative to the base 400, the operating member drive groove 424B drives the engagement member drive pin 412 to slide therein, and the sliding direction of the engagement member drive pin 412 in the operating member drive groove 424B is similarly inclined with respect to the moving direction of the operating member driver 424, so that the base engagement member 410 is pivoted or moved, thereby realizing the base engagement member 410 moving toward the disengaged position.

[0283] As another example, the operating member driving unit 424 may be provided with a driving groove 424C (see FIG. 84) extending along the front-rear direction of the base 400. The driving groove 424C is similar to the operating member long groove 421A in the first embodiment, and is used to mate with a base protrusion 460 (see FIGS. 80 and 81) in the base 400, thereby limiting the movement of the operating member driving unit 424 relative to the base 400.

[0284] 83 to 88, an embodiment will be described in which the rotation of the operation member rotation portion 423 directly drives and moves the operation member drive portion 424. In this embodiment, the operation member rotation portion 423 acts directly on the operation member drive portion 424.

[0285] In order to move the operating member rotating part 423 in conjunction with the operating member driving part 424, as shown in FIG. 86, the operating member rotating part 423 is provided with a long rotating part interlocking groove 423A, and the operating member driving part 424 is provided with a long driving part interlocking groove 424A, and the operating member driving shaft 426 passes through the rotating part interlocking groove 423A and the driving part interlocking groove 424A simultaneously, so that the operating member rotating part 423 can drive and move the operating member driving part 424 by the operating member driving shaft 426.

[0286] More specifically, when operation member rotation unit 423 is rotated by user operation, rotation unit interlocking groove 423A in operation member rotation unit 423 rotates accordingly, whereby rotation unit interlocking groove 423A drives and moves operation member drive shaft 426 passing through it. Since operation member drive shaft 426 also passes through drive unit interlocking groove 424A in operation member drive unit 424 at the same time, when operation member drive shaft 426 abuts against the end of drive unit interlocking groove 424A during movement, operation member drive shaft 426 moves operation member drive unit 424, thereby realizing that operation member rotation unit 423 moves and moves operation member drive unit 424 via operation member drive shaft 426.

[0287] 86, a drive unit return elastic member 424D is provided on the carrier 1. The drive unit return elastic member 424D is installed so as to drive the operating member drive unit 424 to move it toward its initial position, so that when the user no longer acts on the operating member rotation unit 423, the operating member drive unit 424 returns to its initial position by the elastic force of the drive unit return elastic member 424D, and at the same time, the operating member drive unit 424 further drives the operating member rotation unit 423 via the operating member drive shaft 426 so as to return it to its initial position.

[0288] The drive unit return elastic member 424D can be an appropriate elastic member such as a spring, a torsion spring, or a hydraulic rod.

[0289] It should be understood that in the embodiment shown in FIG. 86, the elastic member 424D for returning the drive unit is installed so as to act directly on the operating member drive unit 424, but in other embodiments, the elastic member 424D for returning the drive unit may be installed so as to act directly on the operating member rotation unit 423, whereby the elastic member 424D for returning the drive unit drives the operating member rotation unit 423 to its initial position, and further the operating member rotation unit 423 drives the operating member drive unit 424 by the operating member drive shaft 426 to return it to its initial position.

[0290] Furthermore, the elastic member 424D for returning the drive unit is not essential, and the operating member rotation unit 423 may be installed so as to return to its initial position by operation by the user, and the operating member drive unit 424 is driven by the operating member drive shaft 426 so as to return to its initial position.

[0291] 89 to 91, an embodiment will be described in which the operation member rotation unit 423 indirectly drives and moves the operation member drive unit 424. Unlike the embodiment described above with reference to Figures 83 to 88, in this embodiment, the operation member rotation unit 423 acts indirectly on the operation member drive unit 424.

[0292] 89 and 91, the base operating member 420 further includes an operating member interlocking unit 427. The operating member interlocking unit 427 is installed to transmit the rotation of the operating member rotating unit 423 to the operating member driving unit 424, thereby driving and moving the operating member driving unit 424.

[0293] 89 and 91 show one embodiment of the operating member interlocking part 427. The operating member interlocking part 427 is rotatably connected to the base 400, and is provided with an interlocking part contact end 427A. The interlocking part contact end 427A abuts against the operating member rotating part 423, so that rotation of the operating member rotating part 423 can drive the operating member interlocking part 427 to rotate.

[0294] In order to link the operating member interlocking part 427 and the operating member driving part 424, the operating member interlocking part 427 is also provided with a long interlocking groove 427B, and the interlocking part driving shaft 428 passes through the interlocking groove 427B and the driving part interlocking groove 424A simultaneously, whereby the operating member interlocking part 427 can drive and move the operating member driving part 424 by the interlocking part driving shaft 428.

[0295] More specifically, when operation member rotation portion 423 is rotated by a user's operation, interlocking portion contact end 427A of operation member interlocking portion 427, which abuts against operation member rotation portion 423, is pushed and moved by operation member rotation portion 423, thereby rotating operation member interlocking portion 427. Interlocking portion long groove 427B in operation member interlocking portion 427 then rotates accordingly, and interlocking portion long groove 427B thereby moves interlocking portion drive shaft 428 which passes through it. At the same time, the interlocking unit drive shaft 428 also passes through the drive unit interlocking groove 424A in the operating member drive unit 424, so when the moving interlocking unit drive shaft 428 abuts against the end of the drive unit interlocking groove 424A, the interlocking unit drive shaft 428 moves the operating member drive unit 424, thereby causing the movement of the operating member rotation unit 423 to be first transmitted to the operating member interlocking unit 427, and then the operating member interlocking unit 427 drives and moves the operating member drive unit 424 via the interlocking unit drive shaft 428.

[0296] In order to realize rotation of the operating member linkage portion 427, in one embodiment, as shown in Figures 89 and 91, the operating member linkage portion 427 may include a linkage portion rotation axis 427C, and the operating member linkage portion 427 can rotate around the linkage portion rotation axis 427C.

[0297] It should be understood that the interlocking portion rotation shaft 427C may be formed integrally with the operating member interlocking portion 427, or may be a separate member independent of the operating member interlocking portion 427, and a shaft hole (not shown) for the interlocking portion rotation shaft 427C to rotate within may be formed on the base 400. Alternatively, the interlocking portion rotation shaft 427C may be formed integrally with the base 400, and the operating member interlocking portion 427 may have a shaft hole for the interlocking portion rotation shaft 427C to rotate within.

[0298] 91, the interlocking long groove 427B is provided at the other end of the operating member interlocking part 427 opposite the interlocking part contact end 427A. However, it should be understood that the interlocking long groove 427B may be provided at another position on the operating member interlocking part 427 as long as it can transmit the movement of the operating member rotation part 423.

[0299] 89 and 91, one embodiment of the operation member interlocking portion 427 has been described above, but the present disclosure is not limited thereto. Other structures may be adopted for the operation member interlocking portion 427. For example, the operation member interlocking portion 427 may be a flexible member such as a string, wire, or rope, one end of which is connected to the operation member rotating portion 423 and the other end of which is connected to the operation member driving portion 424. In this way, the operation member interlocking portion 427 can transmit the rotation of the operation member rotating portion 423 to the operation member driving portion 424 and drive and move the operation member driving portion 424.

[0300] 91, a drive unit return elastic member 424D is further provided on the carrier 1. The arrangement and function of the drive unit return elastic member 424D are the same as those described above, and therefore the details will not be repeated here.

[0301] As in the first embodiment, in the second embodiment of the base 400, as shown in FIGS. 83 to 91, the base engagement member 410 may include a front base engagement member 410A and a rear base engagement member 410B that are spaced a certain distance apart in the front-to-rear direction of the base 400. Here, the front base engagement member 410A is located at the front of the base 400, and the rear base engagement member 410B is located at the rear of the base 400. Also, the operation member drive unit 424 may be installed to directly drive the rear base engagement member 410B to move toward the disengagement position, and at the same time indirectly drive the front base engagement member 410A to move toward the disengagement position via a base interlocking member (not shown).

[0302] 84 , 87 , 88 , and 89 , when the base engagement member 410 is pivotable about the engagement member pivot axis 415 of the base 400, an engagement member counterweight 414 is provided on the base engagement member 410 to more stably hold the base engagement member 410 in the engaged position. The engagement member counterweight 414 is installed so that the base engagement member 410 tends to pivot toward the engaged position. For example, the position of the engagement member counterweight 414 on the base engagement member 410 may be a certain distance away from the engagement member pivot axis 415 in the front-to-rear direction of the carrier 1, and the center of gravity of the base engagement member 410 may be located between the engagement member counterweight 414 and the engagement member pivot axis 415 in the front-to-rear direction of the carrier 1, thereby facilitating the generation of a moment for pivoting the base engagement member 410 toward the engaged position.

[0303] In the present disclosure, the engagement member counterweight 414 can be any suitable counterweight member, such as a pillar, a block, etc., as long as its size and weight allow it to engage with the base engagement member 410.

[0304] 87, the rear base engagement member 410B is provided with a rear engagement member counterweight 414B. The rear engagement member counterweight 414B may be installed such that the center of gravity P2 of the rear base engagement member 410B is located between the rear engagement member counterweight 414B and the rear engagement member pivot shaft 415B in the fore-and-aft direction of the carrier 1. Therefore, the center of gravity P2 of the rear base engagement member 410B generates a moment that pivots the rear base engagement member 410B toward the engagement position.

[0305] In one embodiment, the distance X2 between the center of gravity P2 of the rear base engagement member 410B and the center line of the rear engagement member pivot shaft 415B in the front-rear direction of the carrier 1 is equal to 4 mm.

[0306] In yet another embodiment, the center of gravity P2 of the rear base engagement member 410B may be positioned so that it is on substantially the same horizontal plane I2 as the center line of the rear engagement member pivot shaft 415B. For example, the rear engagement member counterweight 414B may be positioned so that the center of gravity of the rear engagement member counterweight 414B and the center line of the rear engagement member pivot shaft 415B are on the same horizontal plane I2. With this structure, if an emergency situation occurs while the vehicle is traveling, such as a collision due to unexpected braking or acceleration, the center of gravity P2 of the rear base engagement member 410B will not generate a moment that causes the rear base engagement member 410B to pivot toward the disengaged position, thereby effectively preventing the rear base engagement member 410B from being unintentionally disengaged from the rear carrier engagement member 108B (see FIG. 74 ) of the carrier 1.

[0307] Optionally, in the embodiment shown in Fig. 88, the front base engagement member 410A is provided with a front engagement member counterweight 414A. The front engagement member counterweight 414A may be installed such that the center of gravity P1 of the front base engagement member 410A is located between the front engagement member counterweight 414A and the front engagement member pivot shaft 415A in the fore-and-aft direction of the carrier 1. Therefore, the center of gravity P1 of the front base engagement member 410A generates a moment that rotates the front base engagement member 410A toward the engaged position.

[0308] In one embodiment, the distance X1 between the center of gravity P1 of the front base engagement member 410A and the center line of the front engagement member pivot shaft 415A in the front-rear direction of the carrier 1 is equal to 17 mm.

[0309] In yet another embodiment, the center of gravity P1 of the front base engagement member 410A may be positioned so that it is on substantially the same horizontal plane I1 as the center line of the front engagement member pivot shaft 415A. For example, the front engagement member counterweight 414A may be positioned so that the center of gravity of the front engagement member counterweight 414A and the center line of the front engagement member pivot shaft 415A are on the same horizontal plane I1. With this structure, when an emergency situation occurs while the vehicle is traveling, such as a collision due to unexpected braking or acceleration, the center of gravity P1 of the front base engagement member 410A does not generate a moment that causes the front base engagement member 410A to pivot toward the disengaged position, thereby effectively preventing the front base engagement member 410A from being unintentionally disengaged from the front carrier engagement member 108A of the carrier 1 (see FIG. 74 ).

[0310] It should be understood that although in the above embodiment, the engagement member counterweight 414 has been described with reference to the second embodiment of the base 400, the engagement member counterweight 414 can be similarly applied to the first embodiment of the base 400.

[0311] Carrier application device

[0312] Next, an embodiment of a carrier application apparatus 500 according to the present disclosure will be described with reference to FIGS.

[0313] It should be noted that in the present disclosure, the carrier application device 500 refers to a device on which the carrier 1 can be placed or applied. Although the carrier application device 500 shown in the drawings is a stroller, the present disclosure is not limited thereto, and the carrier application device 500 according to the present disclosure may further include, but is not limited to, a baby chair for carrying a baby, a child cart for carrying a child, a cart for carrying goods or animals, or a base connectable to a vehicle seat.

[0314] Also, although the carrier 1 shown in the drawings is a basket-type child car seat, the present disclosure is not limited thereto, and the carrier 1 according to the present disclosure can be used to transport people, animals, or goods, including, but not limited to, basket-type child car seats, carrycots, safety seats, animal carriers, or goods carriers, etc.

[0315] The carrier 1 can have various embodiments, for example, a first embodiment of the carrier 1 has a pivotable anchor joint 20 (see FIG. 94), a second embodiment of the carrier 1 has an extendable anchor joint 20 (see FIG. 95), and a third embodiment of the carrier 1 does not have an anchor joint 20 (see FIG. 96).

[0316] For convenience of explanation, a stroller is taken as an example of the carrier application device 500, and a basket-type child seat is taken as an example of the carrier 1.

[0317] Furthermore, the direction in which the baby faces in the stroller 500 is defined as the front, and the direction in which the baby faces away from the stroller 500 is defined as the rear (see Figures 92, 94 to 96), the front-to-rear direction is defined as the longitudinal direction of the stroller 500, and the left-to-right direction perpendicular to the front-to-rear direction is defined as the lateral direction T of the stroller 500 (see Figures 93, 97, and 98). The structure of other forms of carrier application device 500 may be similar to or different from that of the stroller.

[0318] In order to safely and securely connect the basket-type child seat 1 to the stroller 500, the stroller 500 includes an application holding portion that can engage with a carrier holding portion on the basket-type child seat 1, thereby placing the basket-type child seat 1 on the stroller 500.

[0319] 92 to 98, the application holder includes two lateral application holders 510 arranged along the lateral direction T of the stroller 500. Correspondingly, as shown in FIGS. 101 to 103, the carrier holder of the basket-type child car seat 1 includes two lateral carrier holders 1G that engage with the two lateral application holders 510.

[0320] In order to realize engagement between the application holder and the carrier holder, each lateral application holder 510 is provided with a recess 511 (see Figures 93, 98 and 99), and each lateral carrier holder 1G is provided with a protrusion 1G1 (see Figures 101 to 103), and the recess 511 and the protrusion 1G1 can engage with each other.

[0321] In such a case, the distance between the two lateral application holders 510 is very close to the distance between the two lateral carrier holders 1G (to ensure better engagement between the lateral application holders 510 and the lateral carrier holders 1G), so that when the basket-type child seat 1 is placed in the stroller 500, it is relatively difficult for the protrusions 1G1 of the lateral carrier holders 1G to enter the recesses 511 of the lateral application holders 510.

[0322] To facilitate the insertion of the protrusions 1G1 into the recesses 511, in the embodiment shown in FIGS. 103 and 104 , the protrusions 1G1 are arranged so as to be operable to extend from the basket-type child car seat 1 or retract into the basket-type child car seat 1. As shown in FIG. 103 , when the protrusions 1G1 extend from the basket-type child car seat 1, i.e., when the protrusions 1G1 are in the extended position, the distance between the protrusions 1G1 on both sides of the basket-type child car seat 1 is greater than the distance between the recesses 511 on both sides of the stroller 500, which may make it difficult for the basket-type child car seat 1 to reach the connecting position with the stroller 500. Furthermore, as shown in FIG. 104 , when the protrusions 1G1 are retracted into the basket-type child car seat 1, i.e., when the protrusions 1G1 are in the retracted position, the distance between the protrusions 1G1 on both sides of the basket-type child car seat 1 is smaller than the distance between the recesses 511 on both sides of the stroller 500, which makes it easy for the basket-type child car seat 1 to reach the connecting position with the stroller 500. As a result, when placing the basket-type child seat 1 in the stroller 500, the user can first operate the protrusion 1G1 to move it back into the basket-type child seat 1, thereby allowing the basket-type child seat 1 to easily reach the connection position with the stroller 500. Then, after aligning the protrusion 1G1 with the recess 511, the user can operate the protrusion 1G1 to extend it outside the basket-type child seat 1 and insert it into the recess 511, thereby easily completing the engagement between the lateral application holding portion 510 and the lateral carrier holding portion 1G, and holding the basket-type child seat 1 in a position where it can be connected to the stroller 500.

[0323] In one embodiment, the protrusion 1G1 that can extend from the basket-type child seat 1 or retract into the basket-type child seat 1 can employ the connecting pillar 200 described above with reference to Figures 6 to 9 and Figures 22 to 25B.

[0324] Of course, the present disclosure is not limited in this respect.

[0325] The protrusion 1G1, which can extend from the basket-type child car seat 1 or retract into the basket-type child car seat 1, can employ other structures to enable the protrusion 1G1 to extend or retract. For example, a button (not shown) that works in conjunction with the protrusion 1G1 can be provided on the basket-type child car seat 1, and by pressing this button, the protrusion 1G1 can be retracted into the basket-type child car seat 1.

[0326] In addition, each of the lateral application holding portions 510 of the stroller 500 may be provided with a protrusion, and each of the lateral carrier holding portions 1G of the basket-type child seat 1 is provided with a recess. In addition, the lateral application holding portions 510 of the stroller 500 are provided with a protrusion that can be operated to extend or retract from the stroller 500.

[0327] Furthermore, in addition to such an engagement method using concave and convex fitting, the present disclosure can also employ other engagement methods such as engagement between a guide rail and a guide groove.

[0328] The two lateral application holders 510 may be configured by a part of the stroller 500 or may be configured by separate members attached to the stroller 500 .

[0329] 92 to 98, the lateral application holders 510 are formed by separate members attached to the stroller 500. In this embodiment, each lateral application holder 510 formed by a separate member includes a holder engagement end 512 and a holder connection end 513.

[0330] As shown in FIG. 99, the holder engaging end 512 is provided with a recess 511 for engaging with a protrusion 1G1 disposed on the corresponding lateral carrier holder 1G.

[0331] The holding portion connection end 513 may be connected to a hand bar 520 of the stroller 500 (see FIGS. 92 to 98).

[0332] More specifically, as shown in FIGS. 99 and 100, the holder connection end 513 is sleeve-shaped and fitted onto the handlebar 520 of the stroller.

[0333] In order to prevent the lateral application holder 510 from sliding up and down along the hand bar 520, a through hole (see Figure 99) that passes through both the hand bar 520 and the holder connection end 513 can be formed at the connection between the hand bar 520 and the holder connection end 513, and by inserting a screw or pin into the through hole, the holder connection end 513 can be prevented from moving relative to the hand bar 520.

[0334] Although the hand bar 520 shown in the drawings is a lower hand bar, the present disclosure is not limited thereto and the holder connection end 513 may be fitted over the upper hand bar of the stroller. In other embodiments, the holder connection end 513 may be connected to other parts of the stroller 500, such as a seat.

[0335] By engaging the recesses 511 on both sides of the stroller 500 with the protrusions 1G1 on both sides of the basket-type child seat 1, a two-point connection can be achieved between the stroller 500 and the basket-type child seat 1.

[0336] In the case of such a two-point connection, the basket-type child car seat 1 can be placed forward-facing on the stroller 500, i.e., the direction of the baby in the basket-type child car seat 1 matches the forward-facing direction of the stroller 500, so that the baby's line of sight matches the line of sight of the caregiver. Also, the basket-type child car seat 1 can be placed backward-facing on the stroller 500, so that the direction of the baby in the basket-type child car seat 1 matches the backward-facing direction of the stroller 500 (see Figures 94 to 96), so that the caregiver can more conveniently observe the state of the baby in the basket-type child car seat 1.

[0337] Naturally, the present disclosure is not limited thereto. In one embodiment, the application holder may include two longitudinal application holders (not shown) arranged in the front-to-rear direction of the stroller 500. Correspondingly, the carrier holder of the basket-type child car seat 1 may include two longitudinal carrier holders (not shown) that respectively engage with the two longitudinal application holders.

[0338] In yet another embodiment, the application holding portion may be a vertical support (not shown) arranged on the stroller 500, and the carrier holding portion may be a vertical slit (not shown) arranged on the basket-type child seat 1, and the basket-type child seat 1 can be placed on the stroller 500 by engagement of the vertical support and the vertical slit.

[0339] In the case of the above-mentioned two-point connection, in order to maintain balance in the fore-and-aft direction after the basket-type child seat 1 is placed on the stroller 500, the two lateral carrier holding parts 1G of the basket-type child seat 1 may be disposed in the center of the basket-type child seat 1 in the fore-and-aft direction of the basket-type child seat 1. In other words, in order to reduce the tendency of the basket-type child seat 1 to tip over in the fore-and-aft direction, the two lateral carrier holding parts 1G may be disposed as close as possible to the center of gravity of the basket-type child seat 1 in the fore-and-aft direction of the basket-type child seat 1.

[0340] In order to ensure that the basket-type child car seat 1 does not tip forward or backward after being placed in the stroller 500, the present disclosure further provides the following aspects.

[0341] In the first embodiment, the recess 511 and the protrusion 1G1 correspond to each other in shape and size, and are arranged so that the protrusion 1G1 cannot rotate within the recess 511.

[0342] For example, the recess 511 of the application holder may have a rectangular opening (see FIG. 99), and the protrusion 1G1 of the carrier holder is a pillar with a corresponding rectangular bottom (see FIGS. 101 and 102). Furthermore, the sizes of the recess 511 and the protrusion 1G1 also correspond to each other, i.e., the protrusion 1G1 of the carrier holder is slightly smaller in size than the recess 511 of the application holder. Therefore, after the protrusion 1G1 is inserted into the recess 511, the protrusion 1G1 cannot rotate within the recess 511, thereby preventing the basket-type child car seat 1 from tilting forward or backward relative to the stroller 500.

[0343] Of course, the present disclosure is not limited thereto, and the recess 511 of the application holder and the protrusion 1G1 of the carrier holder may be cylindrical with various polygonal, elliptical, or other shapes, as long as it is ensured that the protrusion 1G1 cannot rotate within the recess 511.

[0344] In a second aspect, the application holder may include a longitudinal application holder 530 that is spaced apart from the lateral application holder 510 along the longitudinal direction of the stroller 500. Correspondingly, the carrier holder includes a longitudinal carrier holder 1H that is engageable with the longitudinal application holder 530.

[0345] In the embodiment shown in FIGS. 94 to 97, the vertical application holder 530 may be an armrest of a stroller, and the vertical carrier holder 1H can engage with the armrest 530.

[0346] In one embodiment, the longitudinal carrier holder 1H is configured to be operable to move between a connected position in which it is engaged with the longitudinal application holder 530 and a non-connected position in which it is disengaged from the longitudinal application holder 530.

[0347] In yet another embodiment, the longitudinal carrier holding portion 1H operable to move between a connected position and a disconnected position may employ the connecting hook 300 described above with reference to Figures 12 and 26-29.

[0348] Of course, the present disclosure is not limited in this respect. The vertical application holder 530 may employ another member on the stroller 500, or a separate member may be disposed on the stroller 500 as the vertical application holder 530.

[0349] Similarly, the vertical carrier holding portion 1H may employ another member on the basket-type child seat 1, or a separate member may be disposed on the basket-type child seat 1 as the vertical carrier holding portion 1H.

[0350] By engaging the recesses 511 on both sides of the stroller 500 with the protrusions 1G1 on both sides of the basket-type child seat 1, and by engaging the vertical application holding portion 530 of the stroller 500 with the vertical carrier holding portion 1H of the basket-type child seat 1, a three-point connection can be achieved between the stroller 500 and the basket-type child seat 1, thereby ensuring a more stable connection between the stroller 500 and the basket-type child seat 1.

[0351] In the present disclosure, either the first aspect or the second aspect may be used alone, or both aspects may be used in combination.

[0352] As shown in FIG. 105, after the carrier 1 is placed on the carrier applying device 500, the vertical application holder 530 (e.g., armrest of the carrier 1) of the carrier applying device 500 engages with the vertical carrier holder 1H of the carrier 1 to fix the carrier 1 in the vertical direction of the carrier applying device 500. However, the vertical application holder 530 is usually smooth (see FIG. 106), and the vertical application holder 530 does not adhere perfectly to the carrier 1, so that the vertical application holder 530 cannot restrict the carrier 1 in the horizontal direction of the carrier applying device 500, and therefore the carrier 1 may sway from side to side within a small range, which may result in a potential safety hazard or startle a sleeping child.

[0353] To avoid such a situation, as shown in FIG. 107, the vertical application holder 530 according to the present disclosure may be provided with a holder stop structure 531, which is installed so as to prevent the carrier 1 from swinging.

[0354] 107 to 109, the holder stop structure 531 may be at least two stop protrusions 531 arranged on the longitudinal application holder 530. Two adjacent stop protrusions 531 can hold a part of the carrier 1 therebetween, thereby preventing the carrier 1 from swinging.

[0355] The stop protrusion 531 may have a triangular pyramid shape or other shapes.

[0356] 108 and 109, the two stop protrusions 531 are arranged non-parallel to each other so that the stop protrusions 531 can more effectively prevent the carrier 1 from swinging. This is a preferred embodiment, but the present invention is not limited to this, and the two stop protrusions 531 may also be arranged parallel to each other.

[0357] Specifically, as shown in FIG. 108, the maximum distance Z1 between the two retaining protrusions 531 may be 24 mm, and the minimum distance Z2 between the two retaining protrusions 531 may be 19 mm.

[0358] 108, the length Z3 of each retaining protrusion 531 may be 22 mm, and the width Z4 of each retaining protrusion 531 may be 13 mm. As shown in FIG. 109, the height Z5 of each retaining protrusion 531 may be 3 mm.

[0359] Corresponding to the holder stop structure 531 on the longitudinal application holder 530, the carrier 1 is provided with a carrier stop structure 1K. As shown in FIG. 110, the carrier stop structure 1K may be a protrusion structure on the carrier 1, the shape, size and position of which all correspond to the stop protrusions 531, and the carrier stop structure 1K can be engaged between two adjacent stop protrusions 531. Therefore, the carrier stop structure 1K comes into closer contact with the stop protrusions 531 and prevents the carrier 1 from swinging.

[0360] 107 and 108, at least two stop protrusions 531 are provided with guide slopes 531A, respectively, and two adjacent guide slopes 531A are arranged opposite to each other. The carrier stop structure 1K can be engaged between the two adjacent guide slopes 531A.

[0361] Of course, the present disclosure is not limited in this respect.

[0362] The holder stop structure 531 and / or the carrier stop structure 1K may adopt other structural forms.

[0363] For example, the retainer stop structure 531 may be a recess formed in the longitudinal application retainer 530, which may engage with a convex carrier stop structure 1K formed on the carrier 1 to provide closer contact.

[0364] In another example, the retainer stop structure 531 may be at least one engagement post formed on the vertical application retainer 530, and the engagement post can respectively engage with the same number of engagement hole-shaped carrier stop structures 1K formed on the carrier 1.

[0365] In yet another example, the holder stop structure 531 may be a specific surface (e.g., a curved surface, a corrugated surface, a sawtooth surface, etc.) formed on the longitudinal application holder 530, which can more closely contact the opposing surface on the carrier 1 in a face-to-face, full contact manner to prevent the carrier 1 from rocking. In such an embodiment, there is no need to separately provide the carrier stop structure 1K on the carrier 1.

[0366] In the above description of the representative examples, directional terms (such as "upper," "lower," "left," "right," "front," "rear," etc.) are used for convenience in referring to the drawings. However, it should be expressly understood that the scope of the present disclosure is not limited to any particular orientation described herein.

[0367] Because the features of the present disclosure may be embodied in various forms without departing from the characteristics of the present disclosure, the above embodiments are not limited to any of the details described above, unless otherwise stated, but should be broadly construed as falling within the scope defined by the appended claims, and therefore it should also be understood that all changes and modifications that come within the scope and limits of the claims or equivalents of such scope and limits are to be covered by the appended claims.
