[0039] Reference below Figure 1-Figure 7 A calf rest mechanism according to an embodiment of the present invention is described.

[0040] like Figure 1-Figure 2 As shown, the calf rest mechanism according to the embodiment of the present invention is applicable to a stroller 100 with armrests. The stroller 100 with armrests comprises a frame 10, a seat portion 20, a footrest portion 30 connected to the frame 10 and located below the seat portion 20, and the calf rest mechanism comprises: a clamping structure 31, a flexible cloth 40, a connecting rod 50, and a pressing rod 60. The clamping structure 31 is arranged at the rear side of the footrest portion 30, the flexible cloth 40 is connected to the seat portion 20 and extends downward from the front side of the seat portion 20, the connecting rod 50 is connected to the lower end of the flexible cloth 40, the connecting rod 50 is clamped to the clamping structure 31, and the lower ends of the connecting rod 50 and the flexible cloth 40 are both arranged along the rear edge of the footrest portion 30. The pressing rod 60 presses on at least one side of the flexible cloth 40, and the pressing rod 60 is connected to the rear side of the frame 10.

[0041] According to the calf support mechanism of the embodiment of the present invention, the seat portion 20 and the footrest portion 30 are both connected to the frame 10, the footrest portion 30 is located below the seat portion 20, and the connecting rod 50 is connected to the lower end of the flexible cloth 40. The flexible cloth 40 can be connected to the footrest portion 30 by the clamping connection of the connecting rod 50 and the clamping structure 31 of the footrest portion 30. Since the flexible cloth 40 extends downward from the front side of the seat portion 20, the flexible cloth 40 can form a transition surface between the seat portion 20 and the footrest portion 30. When the child sits on the seat portion 20, both feet step on the footrest portion 30, and the calf is between the seat portion 20 and the footrest portion 30. The transition surface between the seat portion 20 and the footrest portion 30 of the flexible cloth 40 can support the child's calf, so as to improve the comfort of the child on the child seat. When the child sits on the seat portion 20 for a long time, the support of the calf can reduce the child's discomfort and improve the child's riding experience.

[0042] Optionally, the seat portion 20 and the flexible cloth 40 may be an integrated structure, the seat portion 20 is a flexible material that can be unfolded, and the flexible cloth 40 is a part of the seat portion 20. The seat portion 20 is fixed on the frame 10, and the front portion extends downward to form the flexible cloth 40, and a connecting rod 50 is connected to the lower end of the flexible cloth 40, and the connecting rod 50 is fixed by engaging with the footrest portion 30 through the engaging structure 31, so that the seat portion 20 and the flexible cloth 40 are connected together with the footrest portion 30 to form a fixation for the entire seat portion 20.

[0043] It is understandable that the seat portion 20 can be connected to the frame 10 in a variety of ways. The seat portion 20 can be surrounded by a cylindrical connection portion at the connection with the frame 10, and the frame 10 passes through the cylindrical connection portion to fix the seat portion 20. In this way, the seat portion 20 can be disassembled and cleaned as needed to improve the user experience. The seat portion 20 can also be connected to the frame 10 by fasteners, which can make the connection between the seat portion 20 and the frame 10 more secure, prevent the child stroller 100 from being damaged due to excessive force on the seat portion 20, and improve safety.

[0044] Among them, the seat portion 20 can form a riding area in the area where the child rides by a stitching method. In this way, the child's riding can be realized without using a hard structure, making the child ride more comfortable and improving the user's experience.

[0045] The snap-fit ​​structure 31 on the rear side of the pedal portion 30 can be snap-fitted with the connecting rod 50, so that when the seat portion 20 and the frame 10 are in active connection, the flexible cloth 40 can be disassembled through the snap-fit ​​structure 31, thereby realizing the disassembly of the entire seat portion 20, making it convenient for users to clean and improving the user experience.

[0046] Optionally, the seat portion 20 and the flexible cloth 40 may be made of a variety of materials, for example, the seat portion 20 may be made of mesh cloth, so that in summer, when a child sits on the mesh cloth, the child can breathe better, prevent the child from feeling uncomfortable due to the heat, and improve the user experience. The seat portion 20 may also be made of thick cloth with an internal filling layer, so that when a child sits on the seat portion 20 in winter, the child can keep warm. The material can be changed according to user needs.

[0047] like Figure 3-Figure 4 As shown, in some embodiments, the snap-fit ​​structure 31 includes a snap-fit ​​groove 311, and the snap-fit ​​groove 311 is provided with a snap-fit ​​entrance 3111, and the connecting rod 50 is snapped into the snap-fit ​​groove 311 through the snap-fit ​​entrance 3111. The snap-fit ​​structure 31 enables the connecting rod 50 to be detachably connected to the pedal portion 30, thereby realizing the disassembly of the flexible cloth 40 and improving the user experience. The connecting rod 50 is snapped into or out of the snap-fit ​​groove 311 through the snap-fit ​​entrance 3111, which is convenient for disassembly and assembly, and the connecting rod 50 can have a long contact line with the inner surface of the snap-fit ​​groove 311, and the snap-fit ​​is stable.

[0048] The shapes of the snap-in entrance 3111 and the snap-in groove 311 are consistent with those of the connecting rod 50. When the connecting rod 50 is snapped into the snap-in structure 31, the snap-in structure 31 and the connecting rod 50 can be ensured to fit each other, increasing the snap-in area, thereby increasing the stability of the connection between the snap-in structure 31 and the connecting rod 50. The upper end of the snap-in entrance 3111 is lower than the upper end of the snap-in groove 311, and the snap-in structure 31 forms a semi-enclosed space, the opening of which is smaller than the outer diameter of the connecting rod 50. When the connecting rod 50 is snapped into the snap-in structure 31, the connecting rod 50 can be prevented from coming out of the snap-in structure 31, so as to achieve a stable connection between the connecting rod 50 and the snap-in structure 31, thereby increasing the stability of the child stroller 100 in use.

[0049] like Figure 3As shown, in some embodiments, the pedal portion 30 includes a pedal 32, and the engaging structure 31 includes: a strip plate 312, a connecting plate 313 and a clamping plate 314. The strip plate 312 is located at the rear side of the pedal 32. The connecting plate 313 extends forward from the lower edge of the strip plate 312 and connects the pedal 32. The clamping plate 314 extends forward from the upper edge of the strip plate 312 and then bends downward, and a clamping groove 311 is defined between the clamping plate 314, the strip plate 312 and the connecting plate 313. There is a gap between the clamping plate 314 and the pedal 32, and the gap size between the clamping plate 314 and the pedal 32 is smaller than the cross-sectional area of ​​the connecting rod 50. Among them, the gap between the clamping plate 314 and the pedal 32 constitutes a clamping entrance 3111 of the clamping groove 311, and the clamping entrance 3111 is realized by deformation of the clamping plate 314 and / or the connecting plate 313 to realize the clamping of the connecting rod 50 into the clamping groove 311 through the clamping entrance 3111. The pedal 32 can provide a space for children to step on. The clamping structure 31 is connected to the pedal 32 through the connecting plate 313, so as to improve the strength of the clamping structure 31. When the flexible cloth 40 is connected to the clamping structure 31 through the connecting rod 50, the flexible cloth 40 can withstand greater force, thereby preventing the flexible cloth 40 from being damaged and increasing the service life of the stroller 100.

[0050] After the flexible cloth 40 is engaged with the engaging structure 31 through the connecting rod 50, the child's calf is supported. At this time, the lower end of the flexible cloth 40 will tend to drive the connecting rod 50 to move upward under the force. The structure formed by the clamping plate 314 on the strip plate 312 can block the connecting rod 50 in the vertical upward direction, thereby preventing the flexible cloth 40 from falling off and improving the stability of the support of the flexible cloth 40.

[0051] It should be noted that there is no specific restriction on the space size of the engagement groove 311 defined between the card plate 314, the strip plate 312 and the connecting plate 313. It can be selected according to the outer diameter of the connecting rod 50 to ensure that the connecting rod 50 will not easily fall out when engaged in the engagement groove 311.

[0052] like Figure 4 As shown, in some embodiments, the connecting plate 313 is provided with a plurality of first openings 315 along the length direction, and the clamping plate 314 is provided with a plurality of second openings 316 along the length direction, and the plurality of first openings 315 and the plurality of second openings 316 are arranged in a staggered manner. The connecting plate 313 with the first openings 315 can provide a stable connection structure for the clamping structure 31, and based on the openings, the connecting plate 313 and the clamping plate 314 have a certain deformation capacity, and at the same time, the weight of the pedal part 30 can be reduced, saving costs.

[0053] The connecting plate 313 is provided with a plurality of first openings 315, so that when the connecting rod 50 applies pressure to the clamping plate 314 and the connecting plate 313, the connecting rod 50 needs less force to escape from the clamping groove 311, thereby making it easier to disassemble the connecting rod 50. When the rear side of the pedal portion 30 is a curve, the strip plate 312 is also a curve structure, and the plurality of first openings 315 provided on the connecting plate 313 can ensure that the connecting rod 50 is smoothly disassembled from the clamping structure 31.

[0054] The clamping plate 314 can better fix the connecting rod 50. When the connecting rod 50 needs to be inserted into the locking structure 31, the connecting rod 50 is pressed at the locking inlet 3111, so that the clamping plate 314 and the connecting plate 313 are bent and deformed, and the locking inlet 3111 becomes larger, so that the connecting rod 50 can be smoothly inserted into the locking groove 311. The clamping plates 314 are arranged at intervals along the length direction of the strip plate 312, which can make the locking operation of the connecting rod 50 easier on the basis of ensuring the stable connection between the connecting rod 50 and the locking structure 31.

[0055] When the connecting rod 50 is inserted into the engaging structure 31, since pressure needs to be applied to the clamping plate 314 through the connecting rod 50, the user needs to clamp the connecting rod 50 into the engaging structure 31 by hand, and the plurality of second openings 316 provided on the clamping plate 314 can provide operating space for the user. When operating, the user can apply pressure to the connecting rod 50 through the second openings 316 with his fingers, and finally the connecting rod 50 is clamped into the engaging structure 31.

[0056] The clamping plates 314 are separated by the second openings 316, so that when the connecting rod 50 applies pressure to the clamping plates 314, each clamping plate 314 can bend independently of each other, and the force required for the connecting rod 50 to be clamped into the clamping groove 311 is smaller, thereby making it easier to clamp the connecting rod 50. When the rear side of the pedal portion 30 is a curve, the strip plate 312 is also a curve structure, and the independent clamping plates 314 can ensure that the connecting rod 50 is smoothly clamped into the clamping structure 31.

[0057] Optionally, the lower end of the flexible cloth 40 can form a cylindrical structure, and the cylindrical structure is continuously arranged along the length direction of the connecting rod 50, and the connecting rod 50 can be wrapped in the cylindrical structure. When the connecting rod 50 is inserted into the snap-fit ​​structure 31, the flexible cloth 40 is connected to the connecting rod 50 through the snap-in entrance 3111 formed between the clamping plate 314 and the pedal. The flexible cloth 40 is connected to the connecting rod 50 through the continuously arranged cylindrical structure, which can increase the connection area between the connecting rod 50 and the flexible cloth 40, making the structure of the flexible cloth 40 more stable. When the flexible cloth 40 supports the child's calf, the reliability of the support can be increased, thereby increasing the service life of the child stroller.

[0058] Further optionally, the lower end of the flexible cloth 40 can form a cylindrical structure, the cylindrical structure is arranged at intervals along the length direction of the connecting rod 50, the cylindrical structure is arranged corresponding to the second opening 316, and the connecting rod 50 can be covered in the cylindrical structure. When the connecting rod 50 is inserted into the snap-fit ​​structure 31, the flexible cloth 40 is connected to the connecting rod 50 through the snap-fit ​​entrance 3111 formed between the card plate 314 and the pedal. The flexible cloth 40 is connected to the connecting rod 50 through the cylindrical structure arranged at intervals, and the cylindrical structure is connected to the connecting rod 50 through the second opening 316. Therefore, when the connecting rod 50 is inserted into the snap-fit ​​structure 31, the cylindrical structure can be rotated on the connecting rod 50, providing a certain activity margin for the flexible cloth 40, so that the flexible cloth 40 can be stretched to a certain extent when subjected to force, preventing damage caused by pulling, so as to increase the service life of the stroller 100.

[0059] Furthermore, the material of the clamping plate 314 and / or the connecting plate 313 has a deformability, thereby making it easier to clamp the connecting rod 50 while ensuring a stable connection between the connecting rod 50 and the clamping structure 31 .

[0060] like Figure 3 As shown, in some embodiments, the pedal portion 30 includes: a lower pedal 321 and a rear baffle 322, the rear baffle 322 extending upward from the rear edge of the lower pedal 321, and the clamping structure 31 is located at the rear side of the upper end of the rear baffle 322. The lower pedal 321 can provide a stepping space for the child's feet to improve the comfort of the child. The rear baffle 322 can withstand a certain kicking force, especially when the child wears shoes, which can reduce the deformation and tearing of the flexible cloth 40 when the shoes are stepped on.

[0061] Optionally, by connecting the snap-fit ​​structure 31 with the flexible cloth 40, the lower pedal 321, the rear baffle 322 and the flexible cloth 40 form a continuous curved surface. When a child sits on the stroller 100, there is no gap or hard connection structure between the calves and feet, thereby improving the riding comfort of the child.

[0062] like Figure 5-Figure 7 As shown, the stroller 100 with armrests according to the embodiment of the present invention comprises an armrest 70 and a calf support mechanism as described in the above embodiment. The armrest 70 is detachably connected to the frame 10 and is located in front of the seat portion 20.

[0063] According to the child stroller 100 with armrests of the embodiment of the present invention, a detachable armrest 70 is provided on the child stroller, so that the child can place his hands on the armrests when riding, which can improve the comfort of the child. The provision of the armrest 70 can also limit the activity space of the child, prevent the child from falling from the child stroller 100, and increase the safety of the child when riding. In addition, the armrest 70 can be replaced with accessories with other functions to increase the expansibility of the child stroller 100 with armrests.

[0064] It is understandable that the armrest 70 may be of various types, for example, the armrest 70 may be provided as a dining tray for dining, or may be provided with a variety of toys to attract the attention of children. The armrest 70 with multiple functional settings can increase the expandability of the child stroller 100. The armrest 70 is detachable from the frame 10, and the armrest 70 with different functions can be replaced, thereby increasing the expandability of the child stroller 100.

[0065] like Figure 2 , Figure 3 As shown, the pedal portion 30 further includes: two side ears 33, the two side ears 33 are respectively located on the left and right sides of the pedal portion 30, each side ear 33 is connected to the lower pedal 321, the rear baffle 322 and the clamping structure 31, the side ears 33 are formed into a curved arc to be attached to the frame 10, and the side ears 33 are connected to the frame 10 through the first fastener 34. Through the structure of the side ears 33, the pedal portion 30 can be more firmly connected to the frame 10, thereby improving the stability of the child stroller 100.

[0066] The two side ears 33 are respectively connected to the lower pedal 321, the rear baffle 322 and the card mechanism, which can increase the connection area between the footrest 30 and the frame 10, so that the footrest 30 can withstand greater force, thereby increasing the service life of the child stroller with armrests 100. The side ears 33 are fitted with the frame 10 in a curved arc shape, which can increase the contact area between the side ears 33 and the frame 10. The arc surface contact can prevent the footrest 30 from shaking, making the connection between the footrest 30 and the frame 10 more stable.

[0067] It should be noted that the type of the first fastener 34 is not specifically limited here, and the first fastener 34 may include a bolt or a rivet. When the first fastener 34 is a bolt, the footrest can be replaced with a different specification when necessary to improve the expandability of the child stroller 100 with armrests. When the first fastener 34 is a rivet, the footrest 30 is riveted to the frame 10, which can improve the stability of the connection between the footrest 30 and the frame 10, thereby increasing the service life of the child stroller 100 with armrests.

[0068] like Figure 1-Figure 2 As shown, in some embodiments, the child stroller 100 with armrests further includes: a pressure rod 60, which is pressed on at least one side of the flexible cloth 40, and the pressure rod 60 connects the side of the flexible cloth 40 to the frame 10. This can reduce the risk of children extending their feet between the side of the flexible cloth 40 and the frame 10, thereby reducing safety hazards.

[0069] Specifically, there are two edge pressing rods 60, which are pressed on the left and right sides of the flexible cloth 40, and the edge pressing rods 60 are connected to the frame 10 through the second fasteners 61. The two edge pressing rods 60 can stably connect the flexible cloth 40 to the frame 10, and when the child rides on the child stroller, the stable structure of the flexible cloth 40 can ensure the safety of the child, thereby improving the riding experience of the child.

[0070] It should be noted that the type of the second fastener 61 is not specifically limited here, and the second fastener 61 may include a bolt or a rivet. When the second fastener 61 is a bolt, the flexible cloth 40 can be replaced with different types when necessary, for example, a thinner flexible cloth 40 can be replaced in summer to improve air permeability, and a thicker flexible cloth 40 can be replaced in winter to improve warmth retention. By replacing the flexible cloth 40, the expandability of the stroller 100 with armrests can be improved. When the second fastener 61 is a rivet, the flexible cloth 40 is riveted to the frame 10, which can improve the stability of the connection between the flexible cloth 40 and the frame 10, thereby increasing the service life of the stroller 100.

[0071] like Figure 6 As shown, further, the frame 10 is provided with connecting members 11 on the left and right sides above the seat portion 20, and the two connecting members 11 are provided with plug-in parts 111 on the side facing the seat portion 20, and plug-in plates 1111 are respectively provided on the upper and lower sides of the plug-in parts 111. The rear end of the armrest 70 is provided with a mounting groove 71, and the rear end of the mounting groove 71 is open and faces the side of the connecting member 11, and the top and bottom of the mounting groove 71 are respectively formed with slots 711, and the plug-in parts 111 are matched in the mounting groove 71, and the plug-in plates 1111 on the upper and lower sides of the plug-in parts 111 are respectively inserted in the slots 711 on the upper and lower sides. Through the mutual cooperation between the connecting member 11 and the mounting groove 71, the armrest 70 can be disassembled and assembled on the child stroller 100. When the armrest 70 needs to be installed on the frame 10, the slots 711 at the top and bottom of the mounting groove 71 can cooperate with the plug-in plates 1111 on the upper and lower sides of the plug-in part 111, so that the armrest 70 is installed on the frame 10. When a child uses the armrest 70, he or she needs to place his or her hand on the armrest 70, and the armrest 70 will be subjected to a vertical downward force. By cooperating with the slots 711 at the top and bottom and the plug plate 1111, the freedom of the armrest 70 in the vertical direction can be restricted, thereby preventing the mounting groove 71 from detaching from the connector 11, thereby improving the stability of the connection between the armrest 70 and the frame 10.

[0072] Optionally, one of the plug plate 1111 and the slot 711 has a matching groove, and the other of the plug plate 1111 and the slot 711 has a matching rib, and when the mounting slot 71 is inserted into the connector 11, the matching groove and the matching rib fit tightly. Thus, the handrail 70 can be more stably connected to the connector 11.

[0073] like Figure 6-Figure 7 As shown, further, a lock hole 1112 is provided on the plug-in portion 111. A first matching hole 72 and a second matching hole 73 are provided on the armrest 70, the first matching hole 72 is located in the mounting groove 71, and the second matching hole 73 is located at the front side of the mounting groove 71. A lock body assembly 74 is provided on the armrest 70, and the lock body assembly 74 includes: an operating member 741 and a return spring 742. The operating member 741 is swingably connected in the armrest 70, and a pressing portion 7411 and a lock tongue 7412 are provided on the operating member 741, and the pressing portion 7411 is located at the second matching hole 73, and the lock tongue 7412 extends from the first matching hole 72 to the mounting groove 71, and is used to be inserted into the lock hole 1112. The return spring 742 is connected to the operating member 741. Through the cooperation between the lock hole 1112 and the lock body assembly 74, the armrest 70 can be locked after being inserted into the frame 10, thereby improving the stability of the connection between the armrest 70 and the frame 10. By pressing the pressing portion 7411 of the lock body assembly 74, the armrest 70 can be unlocked, so that the armrest 70 can be disassembled more conveniently, thereby improving the user experience.

[0074] When the user needs to fix the armrest 70 on the frame 10, the user aligns the slot 711 with the plug plate 1111 and pushes the armrest 70 toward the frame 10. Since the locking tongue 7412 protrudes from the surface of the mounting slot 71, the locking tongue 7412 will be pressed into the inside of the armrest 70, and the return spring 742 will be compressed under pressure. After the armrest 70 is installed in place, the locking tongue 7412 is located below the lock hole 1112. Due to the elasticity of the return spring 742, the locking tongue 7412 cooperates with the lock hole 1112 to achieve the locking of the armrest 70 and the frame 10.

[0075] When the user needs to disassemble the armrest 70, the user presses the pressing portion 7411 on the operating member 741, and the operating member 741 swings in the armrest 70, and the return spring 742 is compressed. At this time, the locking tongue 7412 and the locking hole 1112 are unlocked, and the armrest 70 is pulled out in a direction away from the frame 10 to achieve disassembly of the armrest 70. After the pressing portion 7411 is released, the operating member 741 is reset due to the elasticity of the return spring 742.

[0076] It should be noted that the type of the return spring 742 is not specifically limited here, and the return spring 742 can be a compression spring or a torsion spring. When the return spring 742 is a compression spring, the compression spring can be compressed by the push of the pressing portion 7411, thereby controlling the movement of the lock tongue 7412 to achieve locking and unlocking of the armrest 70 and the frame 10. When the return spring 742 is a torsion spring, through the same principle, the movement of the pressing portion 7411 can cause the torsion spring to twist, thereby generating stress inside, thereby controlling the movement of the lock tongue 7412 to achieve locking and unlocking of the armrest 70 and the frame 10.
