[0029] To further clarify the object, technical concept and advantages of the present invention, the 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 for interpretation purposes only and do not limit the scope of protection of the present invention.

[0030] When a component is said to be "attached" to another component, it may be directly located to the other component, or there may be an intervening component. When a component is said to be "connected" to another component, it may be directly connected to the other component, or there may be an intervening component simultaneously. The terms "vertical," "horizontal," "left," "right," and similar terms used herein are for illustrative purposes only and do not imply that they represent only one embodiment.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art. Terms used herein are solely for the purpose of describing specific embodiments and are not intended to limit the invention. The terms “and / or” as used herein include any and all combinations of one or more related enumerated items.

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

[0033] Specifically, as shown in Figures 2 and 3, the roof unit 200 comprises 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, an end cap 260, and roof cloth (not shown in the drawings).

[0034] Specifically, as shown in Figures 2 to 4, the first pivot base 210 includes a first disc-shaped portion 211 and a first roof connecting portion 212. One end of the first roof connecting portion 212 is connected to the outer circumference of the first disc-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, and each is detachably attached to both the left and right sides of the headrest portion 120. When the two first pivot bases 210 are attached to both the left and right sides of the headrest portion 120, the groove openings of the first insertion grooves 2121 of the two first pivot bases 210 are both provided facing diagonally 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 both the left and right sides of the headrest portion 120. Since the openings of both first insertion grooves 2121 are positioned diagonally upward, the attached first roof strip 220 also extends diagonally upward relative to the headrest portion 120.

[0035] Specifically, as shown in Figures 2 to 4, the second pivot base 230 includes a second disc-shaped portion 231 and a second roof connecting portion 232. One end of the second roof connecting portion 232 is connected to the outer circumference of the second disc-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 disc-shaped portions 231 of the two second pivot bases 230 can each be pivotally attached to the first disc-shaped portions 211 of the two first pivot bases 210. 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.

[0036] Specifically, as shown in Figures 3 and 4, a second through-hole 233 is provided in the center of the second disc-shaped portion 231, and a part of the end cap 260 is connected to the first pivot base 210 by passing through the second through-hole 233, thereby forming a pivot connection between the second pivot base 230 and the first pivot base 210. The roof cloth is provided to cover the first roof strip 220 and the second roof strip 240, thereby performing functions such as shading, wind protection, and rain protection. Thus, when it is necessary to use the roof unit 200, the cooperation (e.g., relative rotation) of the first pivot base 210 and the second pivot base 230 allows the second roof strip 240 to rotate away from the first roof strip 220, and the roof cloth provided to cover the space between the first roof strip 220 and the second roof strip 240 can be deployed. When the roof unit 200 is not needed, the cooperation (e.g., relative rotation) of the first pivot base 210 and the second pivot base 230 allows the second roof strip 240 to rotate toward the first roof strip 220, and the roof cloth covering the space between the first roof strip 220 and the second roof strip 240 can be folded, 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 portion 120 as an example, its connection mechanism will be described in detail. As shown in Figures 3 and 4, one of the first disc-shaped portion 211 and the second disc-shaped portion 231 is provided with a plurality of positioning grooves 2111, and the plurality of positioning grooves 2111 may be spaced apart in the circumferential direction. The other of the first disc-shaped portion 211 and the second disc-shaped portion 231 is provided with a plurality of positioning protrusions 2311, and the plurality of positioning protrusions 2311 may be spaced apart in the circumferential direction. Each of the plurality of positioning protrusions 2311 can engage with the plurality of positioning grooves 2111. 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 original engaged positioning groove 2111 and engage with another positioning groove 2111. Thus, when the external force is removed, the second pivot base 230 can be fixed in a different position relative to the first pivot base 210, thereby facilitating switching between the deployed and folded states of the roof unit 200, and adjusting the deployment angle of the roof unit 200. Furthermore, the roof elastic member 250 is provided between the second disc-shaped portion 231 and the first disc-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 of folding the roof unit 200.

[0038] Naturally, in other embodiments, the connection 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, does not necessarily have to be an insertion connection; they may be connected by means such as welding or crimping. The first roof strip 220 and the second roof strip 240 do not necessarily have to be U-shaped structures; they may be two straight rods installed opposite each other. Furthermore, 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 only requirement is that the function of switching between the deployed state and the folded state of the roof unit 200 be realized, and the invention is not limited thereto.

[0039] The present invention provides an engagement mechanism for removably connecting a first object to a second object. As shown in Figures 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 storage 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, the insertion portion 322 being insertable into the storage hole 315. When the insertion portion 322 is inserted into the storage hole 315, the first engagement portion can engage with the second engagement portion, thereby fixing the insertion portion 322 in the storage hole 315 or releasing the engagement to move the insertion portion 322 out of the storage 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 Figure 2, there are two engagement mechanisms 300, and the first pivot bases 210 connected to both ends of the first roof strip 220 are each detachably connected to both sides of the headrest section 120 by the two engagement mechanisms 300, thereby ensuring that the roof unit 200 is stably connected to the headrest section 120 by the engagement mechanisms 300. In other embodiments, the engagement mechanism 300 can be provided on the side 124 of the headrest section 120 or on the rear side of the headrest section 120. The rear side of the headrest section 120 is the side opposite the occupant. The engagement mechanism 300 can be provided on one side, both sides, or on the rear side of the seat section 110. The number and connection positions of the engagement mechanisms 300 are not limited here, as long as the roof unit 200 can be detachably fixed to the carrier body 100. The following description will use the engagement mechanism 300 on one side of the headrest section 120 as an example.

[0041] The engagement mechanism 300 can have multiple forms. For example, in one embodiment, as shown in Figures 3 and 4, the engagement mechanism 300 includes a fixed base 310 and a mounting base 320. The fixed base 310 is connected to the side surface 124 of the headrest. The mounting base 320 is connected to the first pivot base 210, and the mounting base 320 is offset from the pivot axis 270 between the first pivot base 210 and the second pivot base 230. In some embodiments, the mounting base 320 may be connected to the second pivot base 230, and the mounting base 320 may be offset from the pivot axis 270 between the first pivot base 210 and the second pivot base 230.

[0042] Furthermore, as shown in Figures 3 and 4, the fixing base 310 includes a fixing lid 311, a fixing body 312, a sealing lid 313, and a return member 314. The fixing body 312 has a storage hole 315 formed in the longitudinal direction. The longitudinal direction of the fixing body 312 is substantially parallel to the insertion direction of the insertion portion 322 of the mounting base 320. In one embodiment, the storage hole 315 is a through hole. In some embodiments, the fixing body 312 includes a first segment 3121 and a second segment 3122 that communicate in the longitudinal direction. The fixing lid 311 is provided at the end of the first segment 3121 of the fixing body 312, and a projection block 31211 is provided on the outer wall of the first segment 3121 of the fixing body 312 where the fixing lid 311 is provided. In one embodiment, two projection blocks 31211 are provided in the circumferential direction on the outer wall of the first segment 3121 of the fixing body 312 where the fixing lid 311 is provided. The fixed body 312 has a first engaging portion on the wall of the storage hole 315. In some embodiments, the second segment 3122 of the fixed body 312 has a first engaging portion on the wall of the storage hole 315, which is separated from the fixed cover 311. In some embodiments, the fixed cover 311 is provided at the end of the first segment 3121 of the fixed body 312, i.e., at the first end of the fixed body 312, and forms the bottom of the storage hole 315. The fixed cover 311 is located within the storage cavity 123, and the first end of the fixed body 312 is also located within the storage cavity 123. In some embodiments, a first through-hole 1211 is provided in the first housing 121, and a second segment 3122 of the fixed body 312 is fitted into the first through-hole 1211. The second segment 3122 of the fixed body 312 is provided to pass through the first through-hole 1211 from one side of the first housing 121 and extend from the other side of the first housing 121. A projection block 31211 in the first segment 3121 of the fixed body 312 abuts against one side of the first housing 121, and the projection block 31211 is located between the fixed cover 311 and the first housing 121 (see Figure 10). The fixed lid 311, the projection block 31211 of the fixed body 312, and the first housing 121 are all provided with fixing holes at corresponding positions, and the first connecting member (not shown in the drawing) passes through the fixing holes in the first housing 121, the projection block 31211, and the upper fixed lid 311 in order, thereby fixing the fixed body 312 and the fixed lid 311 to the first housing 121.The first connecting member may be, for example, a bolt. In some embodiments, the fixing lid 311, the projection block 31211, and the first housing 121 are each provided with two corresponding fixing holes, and correspondingly, there are two first connecting members. In some embodiments, a rib 31212 is provided on the outer wall of the fixing body 312 to stably fix the fixing body 312 and the fixing lid 311 by the first housing 121 and to prevent the fixing body 312 from rotating in the circumferential direction of the first through hole 1211, and the rib 31212 extends longitudinally from the first end to the second end of the fixing body 312. The second end of the fixing body 312, i.e., the end of the second segment 3122 of the fixing body 312, is provided so as to be located outside the storage cavity 123. One end of the rib 31212 located on the second segment 3122 is closer to the second end of the fixing body 312 than to the side wall of the projection block 31211 that is closer to the second segment 3122. Correspondingly, a notch 12111 is provided in the peripheral wall of the first through hole 1211. The rib 31212 is fitted into the notch 12111, and the rib 31212 is locked in place by the notch 12111.

[0043] Furthermore, referring to Figures 5 to 7, the first engaging portion is an engaging groove 316 formed in the second segment 3122 of the fixed body 312. The storage hole 315 extends in the longitudinal direction of the fixed body 312, that is, from its opening to the bottom of the storage hole 315 along substantially the mounting direction of the mounting base 320, and the mounting direction of the mounting base 320 is, for example, parallel to the pivot axis 270 of the first pivot base 210 and the second pivot base 230. The depth direction of the engaging groove 316 extends from its opening 3163 to the bottom 3161 of the engaging groove 316 along substantially the circumferential direction of the storage hole 315, and specifically, the depth extending direction of the engaging groove 316 is substantially perpendicular to the mounting direction of the mounting base 320. The fixed body 312 has a pressing surface 317. In some embodiments, the pressing surface 317 is a sloped surface provided on the edge of the opening of the storage hole 315 and inclined toward the bottom of the storage hole 315, extending into the interior of the storage hole 315. The engagement groove 316 is located on the side of the pressing surface 317 closer to the bottom of the storage hole 315. The engagement groove 316 has a second groove wall 3162, which is installed adjacent to the groove bottom 3161 of the engagement groove 316 and is located on the side closer to the bottom of the storage hole 315. A guide groove 318 is provided on the side wall of the storage hole 315 of the second segment 3122 of the fixed body 312. The groove opening of the guide groove 318 penetrates the edge of the opening of the storage hole 315, and the guide groove 318 is installed extending substantially along the opening of the storage hole 315 toward the bottom of the hole. The guide groove 318 communicates with the engagement groove 316. The guide groove 318 has a first groove wall 3181, the groove opening 3163 of the engagement groove 316 is provided in the first groove wall 3181, and the first groove wall 3181 is connected to the pressing surface 317.

[0044] Referring to Figures 9 and 10, the sealing lid 313 is movably mounted within the storage hole 315. As shown in Figures 11 and 12, if the mounting base 320 is not engaged with the fixed base 310, the sealing lid 313 can seal the opening of the storage hole 315. A first position restricting portion 3155 is provided on the edge of the opening of the storage hole 315, and a second position restricting portion 3132 is provided on the sealing lid 313 that can abut against the first position restricting portion 3155, thereby preventing the sealing lid 313 from escaping from the storage hole 315. In some embodiments, both the first position restricting portion 3155 and the second position restricting portion 3132 are position restricting bosses.

[0045] In some embodiments, referring to Figures 10 and 12, the sealing lid 313 is provided with a guide projection 3131, and the inner wall of the storage hole 315 is provided with a guide groove 3154, and the guide projection 3131 is slidably mounted within the guide groove 3154, thereby allowing the sealing lid 313 to move smoothly into the storage hole 315. In some embodiments, the inner wall of the storage hole 315 is provided with a guide projection 3131, and the sealing lid 313 is provided with a guide groove 3154, and the guide projection 3131 may be slidably mounted within the guide groove 3154.

[0046] Furthermore, referring to Figures 10 and 12, the return member 314 is provided within the storage hole 315 and positioned between the sealing lid 313 and the fixed lid 311. The return member 314 constantly moves the sealing lid 313 toward the opening of the storage hole 315. The return member 314 is, for example, an elastic member such as a spring or an elastic piece. Furthermore, as shown in Figure 12, the fixed lid 311 is provided with a position regulating boss 3111 that protrudes toward the storage hole 315. One end of the return member 314 is fitted onto the position regulating boss 3111, and the other end abuts against the sealing lid 313. This restricts the return member 314 to the storage hole 315 and prevents it from shifting. If the fixing base 310 is not engaged with the mounting base 320, that is, if the roof unit 200 is not attached to the carrier body 100, the return member 314 presses the sealing lid 313 to the opening of the storage hole 315, sealing the opening of the storage hole 315, preventing foreign objects and dust from entering the storage hole 315, and also preventing an adult's or infant's finger from accidentally getting caught inside the storage hole 315, while also making the overall appearance of the infant carrier simpler and more aesthetically pleasing.

[0047] As shown in Figures 5 and 6, the mounting base 320 includes an operating portion 321, a contact portion 322, and a second engaging portion connected to the contact portion 322. In this embodiment, the second engaging portion is an elastic finger 323 that can engage with the engaging groove 316. The operating portion 321 is connected to the first pivot base 210, one end of the contact portion 322 is connected to the operating portion 321, and the other end of the contact portion 322, i.e., the insertion end 3221, extends away from the operating portion 321. As shown in Figure 7, the contact portion 322 can be inserted into the housing hole 315, and the operating portion 321 can abut against the opening of the housing hole 315, thereby restricting the movement stroke of the contact portion 322 within the housing hole 315 and preventing the operating portion 321 from being pushed into the housing hole 315. As shown in Figure 7, the insertion portion 322 and the storage hole 315 are arranged such that when the insertion portion 322 is inserted into the storage hole 315 and the first engaging portion engages with the second engaging portion, the insertion end 3221 of the insertion portion 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 portion 321. With this setup, when the operating portion 321 is pressed and the insertion portion 322 is driven to move toward the bottom of the storage hole 315, the engagement between the first engaging portion and the second engaging portion is released.

[0048] Specifically, referring to Figures 4 and 5, the insertion portion 322 has a cylindrical structure, for example, a cylindrical body or cylindrical tube, and the storage hole 315 is a cylindrical hole that can be inserted and fitted into the insertion portion 322. The cylindrical or cylindrical design allows the force received by the insertion portion 322 to be more uniform. Referring also to Figure 6, the insertion portion 322 has a hollow cavity, and an opening portion 3222 is provided in the cavity wall of the hollow cavity, and one end of the elastic finger 323 is connected to the hole wall 3223 of the opening portion 3222. A gap exists between the other end of the elastic finger 323 and the other hole wall of the opening portion 3222, which makes the elastic finger 323 more deformable. Naturally, in some embodiments, the insertion portion 322 does not have a hollow cavity, and a slot (not shown in the drawing) is provided in the side wall of the insertion portion 322, one end of the elastic finger 323 is connected to the edge of the groove of the slot, and a gap may also exist between the other end of the elastic finger 323 and the groove wall of the slot, thereby making the elastic finger 323 more deformable.

[0049] In some embodiments, the elastic finger 323 and the insertion portion 322 are integrally molded, which increases the connection strength between the elastic finger 323 and the insertion portion 322 and makes processing easier. Of course, in some embodiments, the elastic finger 323 and the insertion portion 322 may be formed by connecting two independent members by welding, riveting, or other means.

[0050] Referring further to Figures 5 and 6, the elastic finger 323 includes an elastic body 3231 and a locking projection 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 insertion portion 3222, and the free end 3234 extends diagonally outward from the connecting end 3233, away from the insertion end 3221 of the insertion portion 322, and away from the outer circumferential surface of the insertion portion 322. In this embodiment, the locking projection 3232 is provided on the free end 3234. Of course, in some embodiments, the locking projection 3232 may be provided between the free end 3234 and the connecting end 3233.

[0051] Referring to Figures 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 storage hole 315, the elastic finger 323 is in its natural state, and the connecting end 3233 and at least a portion of the locking projection 3232 are located on both sides of the reference plane S. For the sake 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 further away from the groove opening 3163 of the engagement groove 316 is defined as the second side. In this embodiment, during the process of inserting the insertion portion 322 into the storage 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 projection 3232 is located on the second side of the reference plane S. In some embodiments, the pressing surface 317 presses the elastic finger 323 during the process in which the insertion portion 322 is inserted into the storage hole 315 (see Figure 4), moving the free end 3234 toward the first side, away from the engagement groove 316. In some embodiments, the pressing surface 317 presses and deforms the elastic finger 323 during the process in which the insertion portion 322 is inserted into the storage hole 315, positioning the entire locking projection 3232 toward the first side of the reference surface S, thereby allowing the locking projection 3232 to move over the pressing surface 317 and enter the guide groove 318. After entering the groove opening 3163 of the engagement groove 316, the locking projection 3232 tends to return to its original state due to the elastic restoring force of the elastic finger 323, thereby engaging with the engagement groove 316. As the insertion portion 322 of the mounting base 320 is inserted into the storage hole 315, the pressure from the pressing surface 317 causes at least a portion of the elastic finger 323 to enter the guide groove 318, and the entire locking projection 3232 is positioned on the first side of the reference surface S. When the locking projection 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 restoring force, thereby engaging with the engagement groove 316. The guide groove 318 allows the elastic finger 323 to enter and engage with the engagement groove 316 more smoothly.When the elastic finger 323 engages with the engagement groove 316, the groove bottom 3161 of the engagement groove 316 has a pressing force against the locking projection 3232 toward the first side of the reference surface S, and the elastic body 3231 has an elastic restoring force against the locking projection 3232 toward the second side of the reference surface S. These two forces balance each other to lock the locking projection 3232 within the engagement groove 316. The elastic body 3231 always has an elastic force that moves the locking projection 3232 toward the second side of the reference surface S.

[0052] Furthermore, referring to Figures 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 projection 3232 and the elastic body 3231. Naturally, in some embodiments, the guide surface 3235 may be a guide arc surface connected between the locking projection 3232 and the elastic body 3231. The second groove wall 3162 is provided to press against the guide surface 3235 during the process in which the insertion portion 322 is pushed toward the bottom of the housing hole 315 after the locking projection 3232 has been locked in the engagement groove 316, thereby deforming the elastic finger 323 and moving the free end 3234 on which the locking projection 3232 is provided into the insertion portion 322, thereby releasing the engagement with the engagement groove 316. The guide surface 3235 can perform a guiding action against the relative movement of the second groove wall 3162.

[0053] Specifically, as shown in Figures 7 and 8, when the insertion portion 322 is inserted into the storage hole 315 and the locking projection 3232 is engaged with the engagement groove 316, pressing the operating portion 321 moves the insertion portion 322 toward the bottom of the storage hole 315. As a result, as shown in Figure 10, the second groove wall 3162 presses against the guide surface 3235, deforming the elastic finger 323 inward into the fixed base 310, that is, deforming it inward along the radial direction of the storage hole 315, until the locking projection 3232 can exit the engagement groove 316. At this time, the elastic finger 323 is no longer pressed by the groove bottom 3161. The locking projection 3232 moves toward the second side of the reference surface S due to the action of the elastic recovery force of the elastic body 3231. At this time, the pressing force on the operating part 321 is canceled, and referring to Figures 10 and 12, the engagement between the locking projection 3232 and the engagement groove 316 is released, so the sealing lid 313 moves toward the opening of the storage hole 315 by the action of the return member 314, and at the same time the sealing lid 313 presses against the insertion part 322 so that the insertion part 322 moves in the same direction. At this time, since the locking projection 3232 is located on the second side of the reference surface S, even if the insertion part 322 retracts to a position where the locking projection 3232 engages with the engagement groove 316, the locking projection 3232 does not engage with the engagement groove 316 again. In this embodiment, the extending direction of the storage hole 315, that is, the direction from the opening to the bottom of the storage hole 315, is approximately horizontal when the infant carrier is in use. Thus, when the insertion portion 322 is inserted into the storage hole 315, the gravity of the insertion portion 322 itself has almost no component force in the direction extending of the storage hole 315. Therefore, during the use of the infant carrier, it is possible to prevent the engagement between the mounting base 320 and the fixing base 310 from being released due to factors such as unevenness in the road surface or the weight of the roof unit 200.

[0054] In some embodiments, as shown in Figures 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 Figure 15, the fixed base 310 is provided with a storage hole 315 and a first engagement portion. As shown in Figure 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 Figure 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 circumference of the first disc-shaped portion 211, and the other end of the insertion portion 322 extends away from the first disc-shaped portion 211 as an insertion end 3221, and the insertion portion 322 is further provided with an opening 3222. The second engaging portion is an elastic finger 323.

[0055] Specifically, as shown in Figures 15 to 17, the elastic finger 323 includes an elastic body 3231 and a locking projection 3232 protruding from the elastic body 3231. The elastic body 3231 has a connecting end 3233 and a free end 3234 so that it can be manipulated and deformed, the connecting end 3233 is connected to the hole wall 3223 of the opening 3222, and the free end 3234 is further away 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 projection 3232 is provided between the free end 3234 and the connecting end 3233. Of course, in some embodiments, the locking projection 3232 may be provided on the free end 3234. When the insertion portion 322 is inserted into the storage hole 315, the first engaging portion can engage with the second engaging portion, thereby fixing the insertion portion 322 within the storage hole 315. When the locking projection 3232 engages with the engagement opening 319, the locking projection 3232 is designed to be pressed by the inner surface of the wall of the storage hole 315, thereby releasing its engagement with the engagement opening 319. In some embodiments, as shown in Figure 17, the cross-section of the engagement opening 319 is V-shaped, and correspondingly, the cross-section of the locking projection 3232 is V-shaped. By installing them in this manner, the locking projection 3232 can be smoothly released from the engagement opening 319 by the thrusting force from the inner surface of the wall of the storage hole 315. In this embodiment, the engagement mechanism 300 can deform the elastic finger 323 by pressing the elastic body 3231 or the locking projection 3232, and further, it can release the locking projection 3232 from the engagement opening 319, thereby releasing the engagement between the locking projection 3232 and the engagement opening 319.

[0056] Naturally, in some embodiments, the engagement mechanism 300 is not used only for connecting the roof unit 200 and the carrier body 100. The engagement mechanism 300 can also be used, but is not limited to, for connecting 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).

[0057] The above-described infant carrier and its engagement mechanism have at least the following technical effects. In the embodiment of the present invention, the first object and the second object are connected in a detachable manner by an engagement mechanism 300. According to the engagement mechanism 300, the engagement of the first engagement portion and the second engagement portion fixes the insertion portion 322 in the storage hole 315, thereby achieving an engaged connection between the fixing base 310 and the mounting base 320. When it is necessary to separate the first object from the second object, the fixing base 310 can be separated from the mounting base 320 by disengaging the engagement of the first engagement portion and the second engagement portion. The engagement mechanism 300 according to the present invention has a simple structure, is easy to operate, and enables very convenient removal and installation of the first object (carrier body) and the second object (roof unit).

[0058] The technical features of the embodiments described above can be combined in any way, and for the sake of brevity, not all possible combinations of the technical features in the embodiments described above have been described. However, as long as these combinations of technical features are inconsistent, they should be considered to fall within the scope described herein.

[0059] The embodiments described above are merely examples of some embodiments of the present invention, and although the descriptions are relatively specific and detailed, they should not be understood as limiting the scope of the claims. Those skilled in the art will note that, without departing from the concept of the present invention, some further modifications and improvements can be made, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the appended claims. [Explanation of symbols]
