The frame130comprises a front leg131, a rear leg132, and a handle133. The baby carrier200can be a stroller, a baby cradle, a baby swing and a baby playard, etc. Height adjustment of the canopy10can be achieved through the canopy adjustment mechanism100. For example, inFIG.1, the canopy10is at a first height, and inFIG.2, the canopy10is at a second height. The height of the canopy10can be changed to suit children of different heights, and in this way, the installation position of the canopy can be flexibly changed to meet the needs of users. Detailed description of the canopy adjustment mechanism100is as follows.

Please refer toFIGS.3-5. The present invention provides a canopy adjustment mechanism100comprising a canopy10, a locking mechanism and a lock receiving mechanism. The lock receiving mechanism is provided on the canopy10, and the locking mechanism locks at different positions of the lock receiving mechanism to achieve height adjustment of the canopy10. That is, the locking mechanism locks at a first position of the lock receiving mechanism, so that the canopy10is at the first height; and the locking mechanism locks at a second position of the lock receiving mechanism, so that the canopy10is at the second height. In addition, the canopy adjustment mechanism100further comprises a securing base12, which can be provided on the baby carrier200. The canopy10comprises an inserting base13, a first support14and a second support15. The inserting base13is connected to the securing base12, and the first support14and the second support15are pivotally connected to the inserting base13respectively. More specifically, in this embodiment, the first support14and the second support15are rotatably and pivotally connected to the inserting base13through the pivot portion16respectively.

FIGS.3-10illustrate the canopy adjustment mechanism100according to the first embodiment of the present invention. The inserting base13is slidably movable in the securing base12, and the lock receiving mechanism is provided on the inserting base13. The locking mechanism locks at different positions of the lock receiving mechanism, so that the height adjustment of the canopy10relative to the frame130can be achieved. More specifically, the lock receiving mechanism includes locking portions11, and the inserting base13is provided with at least two locking portions11along the axial direction. The locking mechanism includes a locking member30, which can be operated to engage with a locking portion11. When the locking member30is operated to disengage from one of the locking portions11(that is, the locking member30is released from one of the locking portions11), the canopy10can be operated to move, so that the locking member30engages with the other locking portion11. Moreover, the canopy adjustment mechanism100further comprises a driving portion50, and the engagement between the locking member30and the locking portion11is achieved through the action of the driving portion50. It should be noted that the driving portion50may be, but is not limited to, an elastic structure, such as a spring. By using the locking member30to engage with the locking portions11located at different positions in the axial direction of the inserting base13, the height of the canopy10can be changed accordingly. The canopy adjustment mechanism according to the invention is simple in structure and easy to operate.

Please refer toFIG.3. The securing base12has a first through groove124(as shown inFIG.7), and the locking member30has a second through groove31(as shown inFIG.10). The inserting base13slides through the second through groove31and the first through groove124in sequence, but it is not limited thereto. Please refer toFIG.5. One end of the driving portion50is connected to the locking member30, and the other end of the driving portion50is connected to the securing base12. The inserting base13has locking portions11along the axial direction (the direction indicated by K1as shown inFIG.5), and the driving portion50constantly moves the locking member30toward a locking portion11to engage with one of the locking portions11. When the locking member30is operated to disengage from one of the locking portions11, the inserting base13can be operated to move within the first through groove124, so that the locking member30engages with another locking portion11. The driving portion50described above can be a spring, but is not limited thereto. In this embodiment, two locking portions11are provided, but the number is not limited thereto. Surely more locking portions11may be provided as needed. Meanwhile, the engagement between the locking member30and the locking portion11can be achieved by employing a mating connection of two components with convex and concave shapes; for example, a mating connection of a bump and a groove may be used. The inserting base13can move up and down in the second through groove31and the first through groove124, and the locking member30is used to engage with one of the locking portions11, so that the inserting base13is secured at a certain position. By operating the locking member30to overcome the elastic force of the driving portion50, the locking member30can be released from the engagement with the locking portion11. And by pulling the inserting base13up and down so that the locking member30engages with another one of the locking portions11, the inserting base13can be secured at another position, thereby achieving the height adjustment of the canopy10at different positions. More specifically, the inserting base13comprises a connecting base134and a sliding portion135extending along the connecting base134. The sliding portion135sequentially slides through the second through groove31and the first through groove124, and it has the locking portions11along the axial direction.

Please refer toFIG.10. The securing base12comprises a securing base body121and a cover123connected to the securing base body121. The securing base body121has a receiving space125at its top, and the locking member30and the cover123are sequentially mounted into the receiving space125. More specifically, the securing base body121has two lugs122at its top, and the two lugs122and the securing base body121enclose the receiving space125. Moreover, the securing base body121and the cover123each has a corresponding first through groove124. In this embodiment, the securing base12is connected to the frame130. The locking member30is positioned between the securing base body121and the cover123; the inserting base13can sequentially pass through the first through groove124of the cover123, the second through groove31of the locking member30, and the first through groove124of the securing base body121. Further, the lugs122are provided with a first restraining portion1221and a second restraining portion1223that limit the moving distance of the locking member30, so as to ensure that the locking member30will not cause damage to the driving portion50or easily leave the receiving space125. Furthermore, the width of the middle portion38of the locking member30is larger than the width of the two ends37thereof. The locking member30is positioned between the first restraining portion1221and the second restraining portion1223. One end of the locking member30extends out of the first restraining portion1221and is connected to the driving portion50, and the other end of the locking member30extends out of the second restraining portion to form an operating portion32. When the operating portion32is operated, it drives the locking member30to overcome the elastic force of the driving portion50, so that the locking member30can be released from the locking portion11. Since the operating portion32is designed to extend out of the receiving space125, the operating portion32is easy to operate and thus disengagement of the locking member30from the locking portion11can be achieved easily.

FIGS.11-15illustrate the second embodiment of the present disclosure. Please refer toFIG.11. The first support14and/or the second support15is provided with a lock receiving mechanism. With the locking mechanism locking at different positions of the lock receiving mechanism, the length of the first support14and/or the second support15can be changed accordingly, so that height adjustment of the canopy10relative to the frame130can be achieved. More specifically, the first support14and the second support15each includes a securing portion141and a canopy bar143slidably connected to the securing portion141. That is, the purpose of height adjustment of the canopy10can be fulfilled by achieving the height adjustment of the first support14at different positions through adjusting the lock receiving mechanism at different positions on the first support14, and also by achieving the height adjustment of the second support15at different positions through adjusting the lock receiving mechanism at different positions on the second support15. It is certain that the height adjustment can be achieved by using both the first support14and the second support15at the same time. In this embodiment, the height adjustment of the first support14is taken as an example for illustration purposes; the height adjustment of the second support15can be achieved by adopting a structure similar to that of the first support14, which will not be described in detail here.

Please refer toFIG.13for specific details. The securing portion141is provided with a lock receiving mechanism; the locking mechanism can be a separate element or provided on the canopy bar143. It is certain that one of the securing portion141and the canopy bar143is provided with a locking mechanism, and the other of them is provided with a lock receiving mechanism. In this embodiment, a situation where the securing portion141is provided with a lock receiving mechanism and the locking mechanism is a separate element is specifically explained. Other situations will definitely become apparent with reference to this embodiment. Specifically, the first support14comprises the securing portion141connected to the inserting base13and the canopy bar143slidably connected to the securing portion141. It can be understood that the securing portion141and the canopy bar143slide relative to each other, and the height adjustment of the first support14at different positions is achieved by engaging the locking portion11with the locking member30so as to cause the securing portion141and the canopy bar143secured at different positions. Please refer toFIGS.13-15. The canopy bar143has insertion holes1431, and each securing portion141has an elongated groove1411that matches with an insertion hole1431. The lock receiving mechanism includes locking portions11, and the driving portion50is configured to protrude from two sides of the elongated groove1411, with the locking portions11located within the elongated groove1411. The locking mechanism includes a locking member (not shown). The locking portions11are arranged along the length direction of the elongated groove1411(the direction indicated by K2as shown inFIG.13). The locking member is configured to pass through the locking portion11and the insertion hole1431. The locking member is a separate element and may be, but is not limited to, a pin, a rivet, etc. In other embodiments, the locking member protrudes from the canopy bar143and is integrally formed with the canopy bar143, while the above effects can still be achieved. The canopy adjustment mechanism100further comprises the driving portion50, and the engagement between the locking member30and one locking portion11is achieved through the action of the driving portion50. It should be noted that the driving portion50may be, but is not limited to, an elastic structure. With the help of the driving portion50, engagement between the locking portion11and the locking member is achieved, thereby securing the securing portion141and the canopy bar143relative to each other. The canopy bar143is operated to move, driving the locking member to disengage from one of the locking portions11, and therefore, the locking member can move to another position in the elongated groove1411to engage with another locking portion11. Since the driving portion50is configured to protrude from the elongated groove1411, the width of the elongated groove1411is reduced at certain point to form the locking portion11in the elongated groove1411. Moreover, the securing portion141has arc-shaped grooves1412located close to two sides of the elongated groove1411, with each arc-shaped groove1412protruding toward the direction of the elongated groove1411; the driving portion50is located between the arc-shaped groove1412and the elongated groove1411. Since the arc-shaped groove1412protrudes toward the direction of the elongated groove1411, the elasticity of the driving portion50can be further improved. The arc-shaped groove1412has a first curved edge1413and a second curved edge1414. Both of the first curved edge1413and the second curved edge1414protrude toward the elongated groove1411, thereby improving the buffer performance of the driving portion50to achieve smooth buffering; also, the service life of the driving portion50can be extended. During use, when an external force pulls the canopy bar143outward, the locking member30moves along with the canopy bar143to overcome the buffering elasticity of the driving portion50between the elongated groove1411and the arc-shaped groove1412. As a result, the locking member30disengages from one of the locking portions11and moves to the other one of the locking portions11to engage therewith, and the height adjustment of the canopy bar143is then achieved.

FIGS.16-19illustrate the third embodiment of the present disclosure. In this embodiment, the first support14is taken as an example to describe its height adjustment; the second support15can adopt a structure similar to the one with the first support14to achieve the height adjustment thereof, which will not be described in detail here. Please refer toFIGS.18-19. The securing portion141has a sliding groove1415that allows the canopy bar143to slidably move therein, and the canopy bar143has locking portions11along the axial direction (the direction indicated by K3as shown inFIG.18). The driving portion50is positioned between the locking member30and the securing portion141, and the locking member30can be operated so that it is locked into or released from the locking portions11. More specifically, the securing portion141has a receiving hole1416, and a first end33of the locking member30is inserted into the receiving hole1416to engage with the locking portion11. A second end34of the locking member30is connected to the driving portion50, which has one end connected to the securing portion141. When the locking member30is operated to disengage from one of the locking portions11, the canopy bar143can be operated to move so that the locking member30engages with the other one of the locking portions11. In this embodiment, two locking portions11are provided, but the number is not limited thereto. Further, the first end33of the locking member30is provided with a locking pin36, and a bump portion35is provided between the first end33and the second end34; the locking pin36is inserted into the receiving hole1416to engage with the locking portion11. The securing portion141has a mounting groove1417; the locking member30is disposed in the mounting groove1417and is pivotally connected to the securing portion141at the bump portion35, which has one side abutting against the securing portion141to form a pivot point. Given the bump portion35on the locking member30that abuts against the securing portion141, together with the arrangement of the first end33and the second end34, the locking member30is able to move in a seesaw manner; consequently, it is easy to operate the second end34of the locking member30and thereby cause the locking pin36to disengage from the locking portions11. The canopy bar143has a restraining groove1433, and the securing portion141has a restraining pin1418that cooperates with the restraining groove1433to limit the moving distance of the canopy bar143, so that the canopy bar143can be prevented from leaving the sliding groove1415. During use, when an external force presses the second end34of the locking member30to overcome the elastic force of the driving portion50, the locking member30can be disengaged from the one of the locking portions11. After the disengagement, the canopy bar143is operated to move until the locking member30engages with the other one of the locking portions11, thereby achieving the height adjustment of the canopy bar143.

Compared with the prior art, the canopy adjustment mechanism100according to the present disclosure comprises a canopy10, a locking mechanism and a lock receiving mechanism, wherein the locking mechanism can lock at different positions of the lock receiving mechanism to achieve height adjustment of the canopy. Thus, the canopy adjustment mechanism100can suit children of different heights, and is easy to operate in terms of height adjustment and simple in structure.

Although the present invention has been described in conjunction with preferred embodiments, it is to be understood that the invention is not limited to the embodiments disclosed above and should cover various modifications and equivalent combinations that are made based on the essence of the invention.
