Specifically, the releasing mechanism20includes a first abutting component22. When the frame40is being folded, the trigger10can slidably abut against the first abutting component22to drive the releasing mechanism20for releasing the backrest30to allow the backrest30to fold relative to the frame40. After the backrest30is released, a user can fold the backrest30together with the frame40.

Please refer toFIG.5toFIG.8.FIG.5andFIG.6are partial diagrams of the child carrier100at different states according to the embodiment of the present invention.FIG.7is another partial diagram of the child carrier100according to the embodiment of the present invention.FIG.8is a diagram of the trigger10according to the embodiment of the present invention. As shown inFIG.5toFIG.8, a triggering slanted surface11is disposed on the trigger10. An abutting slanted surface223is disposed on the first abutting component22. The triggering slanted surface11is for slidably abutting against the abutting slanted surface223. Specifically, the trigger10further includes a fixing portion12. The trigger10is installed on the frame40by the fixing portion12, so that the trigger10can move along with a folding movement of the frame40. Therefore, the triggering slanted surface11can slidably abut against the abutting slanted surface223when the frame40is being folded.

Besides, as shown inFIG.8, specifically, in this embodiment, the trigger10can be an arc-shaped structure, so that the trigger10can continuously slidably abut against the abutting slanted surface223when the frame40is being folded. The triggering slanted surface11can be a concave slanted surface. The abutting slanted surface223can be a convex slanted surface. When the frame40is in an unfolded state, the abutting slanted surface223is located inside the triggering slanted surface11. When the frame40is being folded, the trigger10moves along with the folding movement of the frame40to slidably abut against the abutting slanted surface223by the triggering slanted surface11, so that the releasing mechanism20is driven to release the backrest30. However, the present invention is not limited to this embodiment. For example, in another embodiment, it is not necessary to configure the trigger to continuously slidably abut against the abutting slanted surface when the frame is being folded, and the triggering slanted surface and the abutting slanted surface can be a convex slanted surface and a concave slanted surface respectively, or be two convex slanted surfaces. In other words, any mechanism which allows the triggering slanted surface to slidably abut against the abutting slanted surface for driving the releasing mechanism to release the backrest when the frame is being folded, is included within the scope of the present invention.

Please refer toFIG.7,FIG.9andFIG.10.FIG.9is an internal structural diagram of the releasing mechanism20in a locking state according to the embodiment of the present invention.FIG.10is an internal structural diagram of the releasing mechanism20in a releasing state according to the embodiment of the present invention. As shown inFIG.7,FIG.9andFIG.10, a first connecting base31is disposed on an end portion of the backrest30. The releasing mechanism20further includes a second connecting base21and a second abutting component23. The second connecting base21is connected to the frame40. The first connecting base31is rotatably connected to the second connecting base21. A positioning component32is disposed on the first connecting base31. Three positioning holes26are disposed on the second connecting base21and for allowing an insertion of the positioning component32. The backrest30can be positioned at different angles when the positioning component32is inserted into different ones of the three positioning holes26. The first abutting component22and the second abutting component23are slidably disposed on the second connecting base21. An end of the first abutting component22slidably abuts against the second abutting component23. When the trigger10slidably abuts against the first abutting component22, the trigger10drives the first abutting component22to push the second abutting component23to disengage the positioning component32from the corresponding positioning hole26. In this embodiment, the releasing mechanism20is driven to release the backrest30by a cooperation of the first abutting component22and the second abutting component23and a cooperation of the second abutting component23and the positioning component32to. However, the present invention is not limited to this embodiment. Any mechanism which allows the releasing mechanism to release the backrest when the frame is being folded, is included within the scope of the present invention.

Specifically, an installation assembly is disposed inside the first connecting base31. The installation assembly is connected to the positioning component32, so that the positioning component32can be driven by the installation assembly to be inserted into the corresponding positioning hole26. In this embodiment, the positioning component32can be a positioning pin. When the trigger10slidably abuts against the first abutting component22, the first abutting component22can push the second abutting component23, so that the positioning component32can be driven by the second abutting component23to disengage from the corresponding positioning hole26for releasing the backrest30. Understandably, during the aforementioned process, an acting force applied on the positioning component32and provided by the second abutting component23is greater than an acting force applied on the positioning component32and provided by the installation assembly.

As shown inFIG.7,FIG.9andFIG.10, the first abutting component22includes a first movable portion221and an abutting portion222. The first movable portion221is for pushing the second abutting component23. The abutting portion222protrudes out of the second connecting base21and is for slidably abutting against the trigger10, i.e., the abutting slanted surface223is disposed on the abutting portion222. In this embodiment, the abutting portion222protrudes out of the second connecting base21to slidably abut against the trigger10. However, the present invention is not limited to this embodiment. In another embodiment, the trigger10can be configured to stretch into the second connecting base to slidably against the abutting portion.

Please refer toFIG.9toFIG.11.FIG.11is a diagram of the second abutting component23according to the embodiment of the present invention. As shown inFIG.9toFIG.11, the second abutting component23includes a second movable portion231and a first abutting pin232. The second movable portion231is slidably disposed on the second connecting base21. The first abutting pin232is disposed on the second movable portion231and is for being slidably inserted into the corresponding positioning hole26. Furthermore, a guiding slot234is disposed on the second movable portion231. A guiding component211is disposed on the second connecting base21. The guiding component211slidably passes through the guiding slot234. The second movable portion231is driven by a sliding cooperation of the guiding component211and the guiding slot234to slide relative to the second connecting base21along a longitudinal direction of the guiding slot234, and a travel distance of a sliding movement of the second movable portion231is also limited by the sliding cooperation of the guiding component211and the guiding slot234.

Specifically, a periphery of the second connecting base21is an arc-shaped structure. The three positioning holes26are disposed on the periphery of the second connecting base21. The first abutting pin232can be integrally formed with the second movable portion231or be installed on the second movable portion231by a fastening component, such as a screwing member or a riveting member. Besides, the second abutting component23further includes two second abutting pins233pivoted to the second movable portion231and located at two sides of the first abutting pin232. The first abutting pin232and the two second abutting pins233can be inserted into the corresponding positioning holes26respectively, so that the positioning component32can be driven by the first abutting pin232or the second abutting pin233to disengage from the corresponding positioning hole26. In addition, since the periphery of the second connecting base21is the arc-shaped structure, a predetermined range of a swinging movement of each of the second abutting pins233is required when each of the second abutting pins233slides within the corresponding positioning hole26. Therefore, each of the second abutting pins233is pivoted to the second movable portion231by a second installation portion237, so that each of the second abutting pins233can pivot relative to the second movable portion231about the second installation portion237, which enables each of the second abutting pins233to slide within the corresponding positioning hole26smoothly.

In this embodiment, a restraining hole27is further disposed on the second connecting base21and located adjacent to an end of a row of the positioning holes26. The restraining hole27is for the positioning component32to be inserted therein to position the backrest30at a folded position when the backrest30is located at the folded position. In this embodiment, the folded position can be a horizontal position. It should be noticed that, different from the positioning hole26, it is not necessary to configure the first abutting pin232or the second abutting pin233to be inserted into the restraining hole27.

However, the present invention is not limited to this embodiment. In another embodiment, there can be only two positioning holes disposed on the second connecting base, and the second abutting component can include only one second abutting pin located at one side of the first abutting pin. Alternatively, in another embodiment, there can be only one positioning hole disposed on the second connecting base, and there can be no second abutting pin.

As shown inFIG.9andFIG.10, a recovering component24is disposed between the second abutting component23and the second connecting base21and for driving the second abutting component23to recover. A first installation portion236is disposed on the second movable portion231. An end of the recovering component24is fixed on the first installation portion236, and another end of the recovering component24is fixed on the guiding component211. The recovering component24can be a compression spring. When the first abutting component22is driven by the trigger10to push the second abutting component23, the second movable portion231can slide relative to the second connecting base21, so that the positioning component32can be pushed by the first abutting pin232or the second abutting pin233to disengage from the corresponding positioning hole26, and the recovering component24can be resiliently deformed. The resiliently deformed recovering component24can recover the second abutting component23, so that the first abutting pin232and the second abutting pins233are recovered for the positioning component32to be inserted into the corresponding positioning hole26.

Please refer toFIG.0.11andFIG.12.FIG.12is a diagram of the first abutting component22according to the embodiment of the present invention. As shown inFIG.11andFIG.12, a first slanted surface224is disposed on the first abutting component22. A second slanted surface235is disposed on the second abutting component23. The first slanted surface224is for slidably cooperating with the second slanted surface235. When the abutting portion222is driven by the trigger10to move along a first direction, i.e., a direction that the abutting portion222moves toward an interior of the second connecting base21, a sliding cooperation of the first slanted surface224and the second slanted surface235can change a force transmission direction, so that the second abutting component23can be pushed along a second direction different from the first direction by the first abutting component22.

As shown inFIG.9andFIG.10, a resilient component33is disposed between the backrest30and the frame40and for driving the backrest30to pivot to the folded position. Specifically, an accommodating slot34is disposed on the first connecting base31. An engaging portion25is disposed on the second connecting base21. A first end of the resilient component33is fixed on the engaging portion25, and a second end of the resilient component33abuts against a wall of the accommodating slot34. When the second connecting base21rotates relative to the first connecting base31, the resilient component33can be compressed or released accordingly. Preferably, in this embodiment, the engaging portion25can be an engaging block. The resilient component33can be a spring structure. However, the present invention is not limited to this embodiment. For example, in another embodiment, the engaging portion can be an engaging notch for accommodating the first end of the resilient component. Alternatively, in another embodiment, the resilient component can be a torsional spring structure or a leaf spring structure.

Operation of the present invention is described as follows. When the frame40is being folded, the trigger10can move along with the folding movement of the frame40, so that the abutting portion222can be driven to move toward the interior of the second connecting base21by the triggering slanted surface11and the abutting slanted surface223slidably abutting against each other. When the abutting portion222moves toward the interior of the second connecting base21, the first movable portion221can be driven to push the second movable portion231to slide along the longitudinal direction of the guiding slot234by the first slanted surface224and the second slanted surface235slidably cooperating with each other, so that the first abutting pin232and each of the second abutting pins233can be inserted into the corresponding positioning holes26respectively, and the positioning component32, which is inserted into one of the positioning holes26, can be driven by the first abutting pin232or the second abutting pin233to disengage from the corresponding positioning hole26for releasing the backrest30to allow the backrest30to fold relative to the frame40. After the backrest30is released, the user can fold the backrest30together with the frame40.

In contrast to the prior art, the foldable backrest structure of the present application utilizes the releasing mechanism disposed between the backrest and the frame and the trigger disposed on the frame to release the backrest by a cooperation of the releasing mechanism and the trigger when the frame is being folded, so that a user can fold the backrest together with the frame. Therefore, the present invention has an advantage of easy operation. Besides, the present invention further has advantages of simple structure and low manufacturing cost.

Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
