Detailed Description

Although the invention is illustrated and described herein with reference to specific embodiments, the invention is not intended to be limited to the details shown. Rather, various modifications may be made in the details within the scope and range of equivalents of the claims and without departing from the invention.

The description of the directions of "front", "rear", "upper", "lower", etc. are referred to herein for convenience of understanding only, and the present invention is not limited to these directions but may be adjusted according to actual circumstances.

A child car according to the present application will first be described in its entirety with reference to fig. 1 to 2. As shown, the stroller includes a frame, wheels, and a seat. Wherein the frame comprises a linkage mechanism formed by sequentially connecting a front foot 200, an armrest frame 500, a rear foot 300 and a seat frame 400, and the seat frame 400 is arranged between the front foot 200 and the rear foot 300.

The components of the above-described linkage have lateral portions disposed on the left and right sides of the frame. And there is a corresponding lateral portion connection between the two lateral portions of each component, with the lateral portion of the front leg 200 at its lower end, the lateral portion of the armrest frame 500 at its upper end, the lateral portion of the mount 400 at its end connected to the front leg 200, and the lateral portion of the rear leg 300 at its location proximate the rear wheel. .

A first pivot 600 is provided between the front foot 200 near both extended ends and both sides of the mount 400, respectively. A second pivot 700 is provided between the two extended ends of the mount 400 and the two sides of the rear foot 300, respectively. A third pivot 800 is provided between the upper extension ends of the rear legs 300 and the positions of the armrest frame 500 near the extension ends, respectively. The folding mechanism 100 according to the present application is disposed between the two extending ends of the armrest frame 500 and the two extending ends of the front leg 200, respectively.

The pivot axes of the first pivot 600, the second pivot 700, the third pivot 800, and the folding mechanism 100 are all disposed along the lateral direction of the stroller. Thus, each set of linkages is rotationally deformed in a respective lateral plane.

Thus, a set of foldable and deformable link mechanisms are respectively formed at the left side and the right side of the baby carriage. The left and right linkages deform synchronously through the connection of the transverse portions between the components.

Referring now to fig. 3 to 6, a deformation process of the frame of the child car according to the present application will be described. As shown, the linkage can be switched between an extended state in which it is generally triangular and a collapsed state in which it is collapsed, by rotation of the front leg 200, the armrest frame 500, the rear leg 300, and the mount 400 relative to one another.

In the unfolded state, the front leg 200 and the armrest frame 500 are obliquely extended forward and downward in an extended state of approximately 180 degrees, the rear leg 300 is obliquely extended rearward and downward from the armrest frame 500, and the mount 400 is erected between the front leg 200 and the rear leg 300 to form a triangle structure as viewed from the side. In the collapsed state, the front leg 200 and the armrest frame 500 extend generally downward from the folding mechanism 100, the rear leg 300 extends generally downward from the armrest frame 500, and the mount 400 is received between the front leg 200 and the rear leg 300.

In order to control the above-described deformation of the vehicle frame, the folding mechanism 100 between the armrest frame 500 and the front foot 200 is provided in a lockable form. That is, the relative rotation between the armrest frame 500 and the forefoot 200 may be locked in the extended state shown in fig. 3, as well as in the collapsed state shown in fig. 6. In order to facilitate the user's operation, locking and unlocking of the folding mechanism 100 is controlled by an operating member 140 provided in the mount 400, which will be described in detail below.

The folding mechanism 100 according to the present application will now be described with reference to fig. 7A to 8B. As shown, the folding mechanism 100 includes: a housing 110, a rotating member 120, and an engaging member 130. The folding mechanism 100 may further include an operating member 140 and a cable 170, the operating member 140 will be described with reference to fig. 11 to 12.

The housing 110 is used to house or engage other components of the folding mechanism 100. The housing 110 is fixedly mounted to the forefoot 200 and has a disk portion 111. In the case where the forefoot 200 is a tubular member, the housing 110 may be inserted into the forefoot 200. To this end, the housing 110 has a forefoot mounting 112 inserted into the forefoot 200, which extends tangentially from the periphery of the turntable 125 towards the forefoot 200. In the case where the forefoot 200 is of other forms, the form of the forefoot mounting portion 112 may vary accordingly. A housing shaft hole 113 is formed in the center of the disc portion 111 in the lateral direction, and a lateral folding mechanism pivot shaft (not shown) is provided therethrough.

The rotating member 120 is fixedly mounted to the armrest frame 500 and has a dial 125, which dial 125 is rotatably mounted to the disk portion 111 such that the rotating member 120 can rotate relative to the housing 110. A rotating member shaft hole 123 is provided at the center of the turntable 125, and the rotating member shaft hole 123 may be coaxial with the housing shaft hole 113 so that a folding mechanism pivot shaft (not shown) is provided therethrough.

In the case where the armrest frame 500 is a tubular member, the rotation member 120 may be inserted in the armrest frame 500. To this end, the rotating member 120 is provided with a handrail frame mounting portion 124 inserted into the handrail frame 500, which extends outwardly from the periphery of the turntable 125 in a tangential direction of the turntable 125. In the case that the armrest frame 500 is of other forms, the form of the armrest frame mounting 124 may vary accordingly.

The turntable 125 has a first engagement groove 121 and a second engagement groove 122 formed on its periphery. The first and second engaging

grooves

121 and 122 are respectively provided to extend straight from the periphery of the turntable 125 toward the inside of the turntable 125 (shown more clearly in fig. 9B and 10B), pointing approximately at the center of the turntable 125 and the middle of the outer periphery. Alternatively, the extension lines of the first and second engaging

grooves

121 and 122 pass through substantially the middle of the radius of the turntable 125 perpendicular thereto, respectively.

The second engagement groove 122 is spaced apart from the first engagement groove 121 along the rotation direction of the rotation member 120. In one embodiment, the second engaging groove 122 is spaced apart from the first engaging groove 121 by 120-150 degrees along the circumferential direction of the turntable 125. The first engaging groove 121 corresponds to an expanded state of the link mechanism, and the second engaging groove 122 of the folding mechanism 100 corresponds to a folded state of the link mechanism.

The position of the first engagement groove 121 on the periphery of the turntable 125 is set such that the front foot 200 and the armrest frame 500 are in an expanded state of approximately 180 degrees about the rotational direction of the rotating member 120 when the first engagement groove 121 faces the engagement piece 130. The position of the second engagement groove 122 on the periphery of the dial 125 is set such that the engagement piece 130 can be slidably inserted into the second engagement groove 122 to lock the rotation member 120 against rotation relative to the housing 110 when the second engagement groove 122 faces the engagement piece 130.

In one embodiment, the first engagement groove 121 is a chute formed on the circumference of the turntable 125 at an angle offset from the radial direction of the turntable 125. The second engagement groove 122 is another inclined groove formed on the periphery of the turntable 125 in the same manner as the inclined groove.

The engaging member 130 is provided in the housing 110 and reciprocally slidably enters the disc portion 111. As the dial 125 rotates relative to the disc portion 111, when the first engagement groove 121 faces the engagement piece 130, the engagement piece 130 can be slidably inserted into the first engagement groove 121 to lock the rotation member 120 from rotating relative to the housing 110.

The elastic member 180 is disposed between the housing 110 and the engaging member 130, and is used to bias the engaging member 130 to slide toward the turntable 125. In the present embodiment, the elastic member 180 is provided as a compression spring. In other embodiments, the resilient member 180 may be provided in any suitable form that biases the catch 130 toward the rotating member 120.

In the case where the first engagement groove 121 and the second engagement groove 122 are provided with the inclined grooves, the end of the engagement member 130 facing the rotation member 120 is provided with the inclined groove 131, and the inclined groove 131 has a shape corresponding to the inclined groove to engage with the inclined groove in a shape-fitting manner.

One end of the cable 170 is inserted into the engaging member 130, and the other end extends out of the folding mechanism 100, so that the cable 170 can be pulled outwards to overcome the elastic force of the elastic member 180 and drive the engaging member 130 to leave the first engaging groove 121. In the present embodiment, both ends of the cable 170 are respectively hammer-head-shaped with increased diameters, and are respectively inserted and fixed in the cable first fixing portion 132 of the engaging member 130 and the cable second fixing portion 162 (fig. 12) of the slider 160.

The cable 170 is shown extending straight in fig. 8A to 8B to show its overall form, however it will be appreciated that in actual use the cable 170 extends inside the armrest frame 500 and the seat frame 400 to connect between the operating member 140 and the folding mechanism 100.

The operation device 101 according to the present application will now be described with reference to fig. 11 to 12. As shown in the figure, the operation device 101 includes: a fixed seat 150, a sliding block 160 and an operating component 140.

Is fixedly mounted to the mount 400 for mounting the slider 160 and provides a sliding rail to allow the slider 160 to slide in a direction toward and away from the mount 400.

The slider 160 is slidably mounted on the fixed base 150, and the cable 170 is fixed to the slider 160. The slider 160 is provided as two sliders 160, and the two sliders 160 are fixed to the two cables 170, respectively, and are disposed bilaterally symmetrically to each other, so that the slider slopes 161 of the sliders 160 are disposed bilaterally symmetrically.

The operating member 140 is slidably (e.g., slidably in a left-right direction) mounted on the fixed base 150 and operatively coupled to the slider 160, and the slider 160 is slidably moved by pressing the operating member 140. The operating member 140 has a driving inclined surface 141, and the slider 160 has a slider inclined surface 161, and the driving inclined surface 141 and the slider inclined surface 161 are coupled to each other such that the pressing movement of the operating member 140 is converted into a lateral line movement of the slider 160 perpendicular to the pressing direction. In the case where two sliders 160 are provided, the operating member 140 forms two driving slopes 141 arranged symmetrically left and right corresponding to the slider slopes 161 of the two sliders 160, so that the two sliders 160 can be driven to slide in opposite directions to each other by pressing the operating member 140.

Thus, when the user depresses the operating member 140 toward the mount 400, the operating member 140 will slide the slider 160 toward the center of the mount 400, thereby moving the cable 170 toward the center of the mount 400.

In other embodiments, the operating member 140 may be provided in any suitable form so long as the cable 170 is slid toward the center of the mount 400.

The operation of the folding mechanism 100 according to the present application will now be described with reference to fig. 9A to 10B.

In fig. 9A and 9B, the folding mechanism 100 is in the unfolded state, and at this time, the engaging piece 130 is inserted into the first engaging groove 121 of the rotating member 120, and the relative rotation between the housing 110 and the rotating member 120 is locked. In this case, the front foot 200 and the armrest frame 500 extend in opposite directions from each other. Because the folding mechanism 100 locks the relative rotation between the front foot 200 and the armrest frame 500, the frame's linkages are locked in the delta configuration.

When the user desires to fold up the child car, the operating member 140 can be depressed toward the seat frame 400 to pull the cable 170. The cable 170 drives the engaging member 130 to move away from the rotating member 120 against the biasing force of the elastic member 180, i.e. to be disengaged from the first engaging groove 121. At this time, the housing 110 and the rotating member 120 may relatively rotate. The user can rotate the armrest frame 500 toward the front leg 200, the rear leg 300 will also be folded toward the front leg 200, and the seat frame 400 will be folded between the front leg 200 and the rear leg 300, so that the frame (and the folding mechanism 100) will reach its folded state. At this time, the second engaging groove 122 of the rotating member 120 is aligned with the engaging member 130, and the engaging member 130 will be snapped into the second engaging groove 122 under the biasing action of the elastic member 180, so as to lock the folding mechanism 100 in its folded state, and achieve the state shown in fig. 10A and 10B.

When the user needs to deform the frame from the collapsed state to the expanded state, the above steps need only be performed in reverse.

In summary, the present application provides a new buggy that is able to control the unfolding and folding of the frame by means of an operating device provided in the seat frame. The present application also provides a folding mechanism that can be used with the child's vehicle of the present application. It will be appreciated that the folding mechanism can be applied to any other suitable device.

While preferred embodiments have been shown and described herein, it should be understood that these embodiments are presented by way of example only. Many modifications, changes, and substitutions will now occur to those skilled in the art without departing from the spirit of the invention. Accordingly, it is intended that the appended claims cover all such modifications as fall within the spirit and scope of the invention.
