[0029] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in more detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only for interpreting the present invention and do not limit the protection scope of the present invention.

[0030] It should be noted that when a component is said to be "anchored" to another component, it may be directly located on the other component, or there may be intervening components. When a component is said to be "connected" to another component, it may be directly connected to the other component, or there may be intervening components present. As used herein, terms such as "vertical," "horizontal," "left," "right," and similar expressions are for illustrative purposes only and do not imply the only embodiment.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terms used herein are for the purpose of describing particular embodiments only and are not intended to limit the invention. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0032] One embodiment of the present invention proposes an infant carrier, such as a stroller or a child car seat. As shown in FIGS. 1 and 2 , taking a child car seat as an example, the infant carrier includes a carrier body 100, a roof unit 200, and an engagement mechanism 300, and the roof unit 200 is detachably connected to the carrier body 100 by the engagement mechanism 300. Specifically, the carrier body 100 includes a seat portion 110 and a headrest portion 120 connected to the seat portion 110, and the roof unit 200 is connected to a side surface 124 of the headrest portion 120 by the engagement mechanism 300. Specifically, referring to FIGS. 3 and 4 , the headrest portion 120 includes a first housing 121 and a second housing 122, and the first housing 121 and the second housing 122 surround each other to form a storage cavity 123.

[0033] Specifically, as shown in Figures 2 and 3, the roof unit 200 includes a first pivot base 210, a first roof strip 220, a second pivot base 230, a second roof strip 240, a roof elastic member 250, end caps 260, and a roof fabric (not shown in the drawings).

[0034] Specifically, as shown in FIGS. 2 to 4 , the first pivot base 210 includes a first disk-shaped portion 211 and a first roof connecting portion 212. One end of the first roof connecting portion 212 is connected to the outer periphery of the first disk-shaped portion 211, and the other end is provided with a first insertion groove 2121. In this embodiment, there are two first pivot bases 210, which are detachably attached to the left and right sides of the headrest portion 120, respectively. When the two first pivot bases 210 are attached to the left and right sides of the headrest portion 120, respectively, the openings of the first insertion grooves 2121 of the two first pivot bases 210 are both obliquely upward. The first roof strip 220 has a U-shaped structure, and both ends of the first roof strip 220 are inserted into the first insertion grooves 2121 of the two first pivot bases 210 on the left and right sides of the headrest portion 120. Since the groove openings of the two first insertion grooves 2121 are both provided facing obliquely upward, the attached first roof strip 220 also extends obliquely upward relative to the headrest portion 120.

[0035] 2 to 4, the second pivot base 230 includes a second disk-shaped portion 231 and a second roof connecting portion 232. One end of the second roof connecting portion 232 is connected to the outer periphery of the second disk-shaped portion 231, and the other end is provided with a second insertion groove 2321. In this embodiment, there are also two second pivot bases 230, and the second disk-shaped portions 231 of the two second pivot bases 230 can be pivotally attached to the first disk-shaped portions 211 of the two first pivot bases 210, respectively. The second roof strip 240 also has a U-shaped structure, and both ends of the second roof strip 240 are inserted into the second insertion grooves 2321 of the two second pivot bases 230, respectively.

[0036] 3 and 4, a second through-hole 233 is provided at the center of the second disk-shaped portion 231, and a portion of the end cap 260 passes through the second through-hole 233 and is connected to the first pivot base 210, thereby forming a pivotal connection between the second pivot base 230 and the first pivot base 210. The roof cloth is provided to cover the outside of the first roof strip 220 and the second roof strip 240, thereby providing functions such as shading, wind protection, and rain protection. In this way, when the roof unit 200 needs to be used, the first pivot base 210 and the second pivot base 230 cooperate (e.g., rotate relative to each other) to rotate the second roof strip 240 away from the first roof strip 220, thereby unfolding the roof cloth provided to cover between the first roof strip 220 and the second roof strip 240. When the roof unit 200 does not need to be used, the first pivot base 210 and the second pivot base 230 cooperate (e.g., rotate relative to each other) to rotate the second roof strip 240 toward the first roof strip 220, and fold the roof cloth covering the first roof strip 220 and the second roof strip 240, thereby significantly reducing the volume occupied by the roof unit 200.

[0037] Furthermore, taking the roof unit 200 located on one side of the headrest 120 as an example, the connection mechanism will be specifically described. As shown in FIGS. 3 and 4 , one of the first disk-shaped portion 211 and the second disk-shaped portion 231 is provided with a plurality of positioning grooves 2111, which may be spaced apart in the circumferential direction. The other of the first disk-shaped portion 211 and the second disk-shaped portion 231 is provided with a plurality of positioning protrusions 2311, which may be spaced apart in the circumferential direction. The plurality of positioning protrusions 2311 can be engaged with the plurality of positioning grooves 2111, respectively. In this way, when an external force is applied to the second pivot base 230 or the second roof strip 240, the second pivot base 230 rotates relative to the first pivot base 210, and each positioning protrusion 2311 can disengage from its originally engaged positioning groove 2111 and engage with another positioning groove 2111. In this way, when the external force is removed, the second pivot base 230 can be fixed at a different position relative to the first pivot base 210, thereby making it convenient to switch the roof unit 200 between the unfolded state and the folded state and to adjust the unfolded angle of the roof unit 200. Furthermore, a roof elastic member 250 is provided between the second disk-shaped portion 231 and the first disk-shaped portion 211. The roof elastic member 250 may be, for example, a torsion spring. The roof elastic member 250 always pivots the second pivot base 230 in the direction to fold the roof unit 200.

[0038] Of course, in other embodiments, the connections between the first pivot base 210 and the first roof strip 220, and between the second pivot base 230 and the second roof strip 240 do not necessarily have to be insertion connections, but may be made by means of welding, crimping, or the like. The first roof strip 220 and the second roof strip 240 do not necessarily have to have a U-shaped structure, but may be two straight rods installed opposite each other, or the like. In addition, the end cap 260 and the roof elastic member 250 do not necessarily have to be provided between the first pivot base 210 and the second pivot base 230. In short, the present invention is not limited to the above as long as the function of switching the roof unit 200 between the unfolded state and the folded state can be realized.

[0039] The present application provides an engagement mechanism for detachably connecting a first object to a second object. As shown in FIGS. 2-3 or 14-15 , the engagement mechanism 300 includes a fixed base 310 and a mounting base 320. The fixed base 310 is connected to the first object, and is provided with a receiving hole 315 and a first engagement portion. The mounting base 320 is connected to the second object, and is provided with an insertion portion 322 and a second engagement portion connected to the insertion portion 322, and the insertion portion 322 is insertable into the receiving hole 315. When the insertion portion 322 is inserted into the receiving hole 315, the first engagement portion can engage with the second engagement portion, thereby fixing the insertion portion 322 in the receiving hole 315 or disengaging the engagement to allow the insertion portion 322 to be removed from the receiving hole 315. In some embodiments, the first object is the carrier body 100 of the infant carrier and the second object is the roof unit 200 of the infant carrier.

[0040] Furthermore, as shown in FIG. 2 , there are two engagement mechanisms 300. The first pivot bases 210 connected to both ends of the first roof strip 220 are removably connected to both sides of the headrest portion 120 by the two engagement mechanisms 300, respectively, thereby ensuring that the roof unit 200 is stably connected to the headrest portion 120 by the engagement mechanisms 300. In other embodiments, the engagement mechanisms 300 may be provided on the side 124 of the headrest portion 120 or the rear side of the headrest portion 120. The rear side of the headrest portion 120 is the side of the headrest portion 120 opposite the occupant. The engagement mechanisms 300 may be provided on one side, both sides, or the rear side of the seat portion 110.

A first position restriction portion 3155 is provided on the edge of the opening of the receiving hole 315, and a second position restriction portion 3132 that can abut against the first position restriction portion 3155 is provided on the sealing lid 313, thereby preventing the sealing lid 313 from slipping out of the receiving hole 315. In some embodiments, the first position restriction portion 3155 and the second position restriction portion 3132 are both position restriction bosses.

[0045] 10 and 12 , in some embodiments, a guide ridge 3131 is provided on the sealing cover 313, a guide groove 3154 is provided on the inner wall of the receiving hole 315, and the guide ridge 3131 is slidably disposed in the guide groove 3154, so that the sealing cover 313 can smoothly move into the receiving hole 315. In some embodiments, a guide ridge 3131 may be provided on the inner wall of the receiving hole 315, and the sealing cover 313 may be provided with a guide groove 3154, and the guide ridge 3131 may be slidably disposed in the guide groove 3154.

[0046] 10 and 12, the return member 314 is provided in the receiving hole 315 and is located between the sealing cover 313 and the fixed cover 311. The return member 314 constantly moves the sealing cover 313 toward the opening of the receiving hole 315. The return member 314 is an elastic member such as a spring or an elastic piece. Furthermore, as shown in FIG. 12, the fixed cover 311 is provided with a position restricting boss 3111 that protrudes toward the receiving hole 315. One end of the return member 314 is fitted onto the position restricting boss 3111 and the other end abuts against the sealing cover 313, thereby restricting the return member 314 within the receiving hole 315 and preventing the return member 314 from slipping out of place. When the fixed base 310 is not engaged with the mounting base 320, i.e., when the roof unit 200 is not attached to the carrier body 100, the restoring member 314 presses the sealing cover 313 up to the opening position of the storage hole 315 to seal the opening of the storage hole 315, preventing foreign objects and dust from entering the storage hole 315 and preventing the fingers of an adult or infant from accidentally getting caught in the storage hole 315, while also making the overall appearance of the infant carrier more simple and beautiful.

[0047] 5 and 6, the mounting base 320 includes an operating portion 321, an insertion portion 322, and a second engagement portion connected to the insertion portion 322. In this embodiment, the second engagement portion is an elastic finger 323 that can engage with the engagement groove 316. The operating portion 321 is connected to the first pivot base 210, one end of the insertion portion 322 is connected to the operating portion 321, and the other end of the insertion portion 322, i.e., the insertion end 3221, extends in a direction away from the operating portion 321. As shown in FIG. 7, the insertion portion 322 can be inserted into the receiving hole 315, and the operating portion 321 can abut against the opening of the receiving hole 315, thereby restricting the movement stroke of the insertion portion 322 in the receiving hole 315 and preventing the operating portion 321 from being pushed too far into the receiving hole 315. 7, the insertion part 322 and the storage hole 315 are arranged such that, when the insertion part 322 is inserted into the storage hole 315 and the first engagement part is engaged with the second engagement part, the insertion end 3221 of the insertion part 322 is spaced apart from the bottom of the storage hole 315, and the opening of the storage hole 315 is also spaced apart from the operating part 321. With this arrangement, when the operating part 321 is pressed to drive the insertion part 322 toward the bottom of the storage hole 315, the engagement between the first engagement part and the second engagement part is released.

[0048] 4 and 5, the insertion part 322 has a tubular structure, such as a cylinder or a cylindrical tube, and the receiving hole 315 is a cylindrical hole that can be inserted and fitted into the insertion part 322. The cylindrical or cylindrical design makes it possible to more uniformly distribute the force received by the insertion part 322. Also, referring to FIG. 6, the insertion part 322 has a hollow cavity, and an opening 3222 is provided in the cavity wall of the hollow cavity. One end of the elastic finger 323 is connected to the hole wall 3223 of the opening 3222. A gap exists between the other end of the elastic finger 323 and the other hole wall of the opening 3222, which makes the elastic finger 323 more easily deformed. Of course, in some embodiments, the insert portion 322 does not have a hollow cavity, but has a slot (not shown in the drawings) on the side wall of the insert portion 322, one end of the elastic finger 323 is connected to the edge of the slot mouth, and there may also be a gap between the other end of the elastic finger 323 and the groove wall of the slot, which makes the elastic finger 323 more easily deformable.

[0049] In some embodiments, the elastic fingers 323 and the insert portion 322 are formed as a single piece, which can increase the connection strength between the elastic fingers 323 and the insert portion 322 and also facilitate processing. Of course, in some embodiments, the elastic fingers 323 and the insert portion 322 may be formed as two separate members connected to each other by welding, crimping, or the like.

[0050] 5 and 6 , the elastic finger 323 includes an elastic body 3231 and a locking protrusion 3232 protruding from the elastic body 3231. The elastic body 3231 has a connecting end 3233 and a free end 3234. The connecting end 3233 is connected to the hole wall 3223 of the opening 3222 of the insert part 322. The free end 3234 is spaced apart from the insertion end 3221 of the insert part 322 relative to the connecting end 3233 and extends obliquely outward away from the outer circumferential surface of the insert part 322. In this embodiment, the locking protrusion 3232 is located on the free end 3234. Of course, in some embodiments, the locking protrusion 3232 may be located between the free end 3234 and the connecting end 3233.

[0051] 5 and 6, the plane on which the groove bottom 3161 of the engagement groove 316 is located is defined as the reference plane S. When the insertion portion 322 is not inserted into the receiving hole 315, the elastic finger 323 is in its natural state, and the connecting end 3233 and at least a portion of the locking protrusion 3232 are located on opposite sides of the reference plane S. For convenience of explanation, the side of the reference plane S closer to the groove opening 3163 of the engagement groove 316 is defined as the first side, and the side of the reference plane S away from the groove opening 3163 of the engagement groove 316 is defined as the second side. In this embodiment, when the insertion portion 322 is inserted into the receiving hole 315, the connecting end 3233 is located on the first side of the reference plane S, and at least a portion of the locking protrusion 3232 is located on the second side of the reference plane S. In some embodiments, the pressing surface 317 presses the elastic finger 323 to move the free end 3234 toward a first side away from the engagement groove 316 during the process of inserting the insertion portion 322 into the receiving hole 315 (see FIG. 4 ). In some embodiments, the pressing surface 317 presses and deforms the elastic finger 323 during the process of inserting the insertion portion 322 into the receiving hole 315, and positions the entire locking protrusion 3232 on the first side of the reference plane S, so that the locking protrusion 3232 overcomes the pressing surface 317 and enters the guide groove 318. After entering the groove opening 3163 of the engagement groove 316, the locking protrusion 3232 has a tendency to return to its original state due to the action of the elastic restoring force of the elastic finger 323, thereby engaging with the engagement groove 316. During the process of inserting the insertion portion 322 of the mounting base 320 into the receiving hole 315, at least a portion of the elastic finger 323 enters the guide groove 318 due to the pressure from the pressing surface 317, and the entire locking protrusion 3232 is located on the first side of the reference plane S. When the locking protrusion 3232 of the elastic finger 323 moves to the engagement groove 316, the pressure from the pressing surface 317 and the first groove wall 3181 against the elastic finger 323 is released, and the elastic finger 323 tends to return to its original state due to the action of its own elastic recovery force, thereby engaging with the engagement groove 316. The guide groove 318 allows the elastic finger 323 to more smoothly enter and engage with the engagement groove 316.When the elastic finger 323 is engaged with the engagement groove 316, the groove bottom 3161 of the engagement groove 316 exerts a pressing force on the locking protrusion 3232 toward the first side of the reference surface S, and the elastic body 3231 exerts an elastic restoring force on the locking protrusion 3232 toward the second side of the reference surface S, and these two forces balance each other to lock the locking protrusion 3232 within the engagement groove 316. The elastic body 3231 has an elastic force that always moves the locking protrusion 3232 toward the second side of the reference surface S.

[0052] 5 and 6 , the elastic body 3231 has a guide surface 3235. In this embodiment, the guide surface 3235 is a guide slope connected between the locking protrusion 3232 and the elastic body 3231. Of course, in some embodiments, the guide surface 3235 may be a guide arc surface connected between the locking protrusion 3232 and the elastic body 3231. After the locking protrusion 3232 is locked in the engagement groove 316, the second groove wall 3162 presses the guide surface 3235 when the insertion part 322 is subsequently pushed toward the bottom of the receiving hole 315, thereby deforming the elastic finger 323 and moving the free end 3234, on which the locking protrusion 3232 is provided, into the insertion part 322 to disengage from the engagement groove 316. The guide surface 3235 can guide the relative movement of the second groove wall 3162.

[0053] 7 and 8, when the insertion portion 322 is inserted into the receiving hole 315 and the locking protrusion 3232 is engaged with the engagement groove 316, the operating portion 321 is pressed to move the insertion portion 322 toward the bottom of the receiving hole 315. As a result, as shown in FIG. 10, the second groove wall 3162 presses the guide surface 3235 to deform the elastic finger 323 toward the inside of the fixed base 310, i.e., deforms it radially inward of the receiving hole 315, until the locking protrusion 3232 can retract from the engagement groove 316. At this time, the elastic finger 323 is no longer pressed by the groove bottom 3161. The locking protrusion 3232 moves toward the second side of the reference plane S due to the elastic recovery force of the elastic body 3231. 10 and 12, the pressing force on the operating portion 321 is canceled, and as a result, the engagement between the locking protrusion 3232 and the engagement groove 316 is released, and the sealing cover 313 moves toward the opening of the storage hole 315 due to the action of the return member 314. At the same time, the sealing cover 313 presses the insertion portion 322 so that the insertion portion 322 moves in the same direction. At this time, because the locking protrusion 3232 is located on the second side of the reference plane S, even if the insertion portion 322 retreats to a position where the locking protrusion 3232 engages with the engagement groove 316, the locking protrusion 3232 does not re-engage with the engagement groove 316. In this embodiment, the extension direction of the storage hole 315, i.e., the direction from the opening to the bottom of the storage hole 315, is substantially horizontal when the infant carrier is in use. In this way, when the insertion portion 322 is inserted into the storage hole 315, the gravity of the insertion portion 322 itself has almost no force component in the direction of extension of the storage hole 315, so that when the infant carrier is in use, factors such as unevenness in the road surface or the weight of the roof unit 200 itself can be prevented from disengaging the mounting base 320 from the fixed base 310.

[0054] In some embodiments, as shown in FIGS. 13 and 14 , the engagement mechanism 300 includes a fixed base 310 and a mounting base 320. The fixed base 310 is connected to the carrier body 100, and the mounting base 320 is connected to the roof unit 200. As shown in FIG. 15 , the fixed base 310 is provided with a storage hole 315 and a first engagement portion. As shown in FIG. 17 , in this embodiment, the first engagement portion is an engagement opening 319 provided on the side wall of the storage hole 315. As shown in FIG. 15 , the mounting base 320 is provided with an insertion portion 322 and a second engagement portion connected to the insertion portion 322. The insertion portion 322 can be inserted into the storage hole 315. One end of the insertion portion 322 is connected to the outer periphery of the first disk-shaped portion 211, and the other end of the insertion portion 322 extends in a direction away from the first disk-shaped portion 211 as an insertion end 3221. The insertion portion 322 is further provided with an opening 3222. The second engagement portion is an elastic finger 323.

[0055] 15 to 17, the elastic finger 323 includes an elastic body 3231 and a locking protrusion 3232 protruding from the elastic body 3231. To allow the elastic body 3231 to be manipulated and deformed, the elastic body 3231 has a connecting end 3233 and a free end 3234. The connecting end 3233 is connected to the hole wall 3223 of the opening 3222, and the free end 3234 is farther from the first pivot base 210 than the connecting end 3233. That is, the extending direction of the elastic body 3231 is substantially the same as the extending direction of the insertion portion 322. In this embodiment, the locking protrusion 3232 is located between the free end 3234 and the connecting end 3233. Of course, in some embodiments, the locking protrusion 3232 may be located at the free end 3234. When the insertion portion 322 is inserted into the receiving hole 315, the first engagement portion can engage with the second engagement portion, thereby fixing the insertion portion 322 within the receiving hole 315. When the locking protrusion 3232 is engaged with the engagement hole 319, the locking protrusion 3232 is configured to be pressed by the inner surface of the hole wall of the receiving hole 315 to disengage from the engagement hole 319. In some embodiments, as shown in FIG. 17 , the cross section of the engagement hole 319 is V-shaped, and correspondingly, the cross section of the locking protrusion 3232 is V-shaped. With this configuration, the locking protrusion 3232 can smoothly disengage from the engagement hole 319 due to the thrust force from the inner surface of the hole wall of the receiving hole 315. The engagement mechanism 300 in this embodiment can deform the elastic finger 323 by pressing the elastic body 3231 or the locking protrusion 3232, and can also cause the locking protrusion 3232 to retreat from the engagement opening 319, thereby releasing the engagement between the locking protrusion 3232 and the engagement opening 319.

[0056] Of course, in some embodiments, the engagement mechanism 300 is not only used to connect the roof unit 200 and the carrier body 100. The engagement mechanism 300 can also be used to connect a first object, such as a handle unit (not shown in the drawings) or a handrail unit (not shown in the drawings), to a second object, such as a frame (not shown in the drawings) or a seat (not shown in the drawings), but is not limited thereto.

[0057] The above infant carrier and its engagement mechanism have at least the following technical effects. In the embodiment of the present application, the first object and the second object are detachably connected by the engagement mechanism 300. According to the engagement mechanism 300, the first engagement portion and the second engagement portion engage with each other, and the insertion portion 322 is fixed in the receiving hole 315, thereby realizing the engagement connection between the fixed base 310 and the mounting base 320. When it is necessary to separate the first object from the second object, the fixed base 310 can be separated from the mounting base 320 by operating to release the engagement between the first engagement portion and the second engagement portion. The engagement mechanism 300 of the present application has a simple configuration and is easy to operate, making it very convenient to detach and attach the first object (carrier body) and the second object (roof unit).

[0058] The technical features of the above-described embodiments can be combined in any manner, and for the sake of brevity, not all possible combinations of the technical features in the above embodiments are described, but as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.

[0059] The above examples merely illustrate some embodiments of the present invention, and the descriptions are relatively specific and detailed, but this should not be understood as limiting the scope of the claims. It should be noted that those skilled in the art can make some modifications and improvements without departing from the concept of the present invention, and all of these are within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be governed by the appended claims. [Explanation of symbols]
