[0002] A stroller is a tool vehicle designed to provide convenience for children's outdoor activities. Families who take their children out usually use strollers, which can reduce the burden of carrying children and give children a comfortable feeling. However, because strollers are too big, they take up a lot of space when placed at home. Therefore, most existing strollers are foldable.

[0003] For example, a utility model patent with application number CN202310016402.X provides a foldable frame structure, belonging to the field of handcart technology, including: a rear frame, which is provided with a hinge seat and a first rotating seat; a front frame, which is hinged to the hinge seat; a handle, which is provided with a second rotating seat, the second rotating seat being rotatably connected to the first rotating seat, the second rotating seat being provided with a hinge block; and a linkage assembly, which includes a first link, a second link, and a third link, the first link being hinged to the rear frame, the second link being hinged to the front frame, and the third link being hinged to the hinge block.

[0004] In conclusion, although some existing technical solutions can achieve overall frame folding, the handlebars are not folded further, leaving considerable room for improvement. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a foldable stroller handle and a children's stroller.

[0006] The objective of this utility model can be achieved through the following technical solution: a foldable trolley handle, comprising:

[0007] A first base body is provided with a limiting hole. The first base body includes a working position and a storage position, and the limiting hole is located between the working position and the storage position.

[0008] The second seat is rotatably connected to the first seat and can be rotated to the working position or the storage position;

[0009] A limiting pin is movably connected to the limiting hole. The limiting pin can extend or retract from the limiting hole. When the limiting pin extends out of the limiting hole, the second seat is restricted from rotating from the working position to the storage position.

[0010] The aforementioned foldable trolley handle also includes a limiting spring, the two ends of which are in contact with the first seat and the limiting pin, respectively, and the limiting spring pushes the limiting pin out of the limiting hole.

[0011] In the aforementioned foldable trolley handle, the limiting pin is provided with a linkage inclined surface. When the second seat rotates from the storage position to the working position, the second seat pushes the limiting pin back into the limiting hole through the linkage inclined surface.

[0012] The aforementioned foldable trolley handle also includes a locking element, which is movably connected to the first seat. When the second seat is in the working position, the locking element is used to lock the second seat and the first seat together.

[0013] In the aforementioned foldable trolley handle, the first base is further provided with a positioning groove, the locking member is always located in the positioning groove, the first base also includes a locking position and an unlocking position, the second base is provided with a locking groove, the locking member is movably connected to the first base and can move to the locking position or the unlocking position, the moving direction of the locking member is parallel to the axis of rotation of the second base around the first base, the locking member is provided with a locking part, when the locking member is in the locking position the locking part is inserted into the locking groove, when the locking member is in the unlocking position the locking part is separated from the locking groove.

[0014] In the aforementioned foldable trolley handle, the first seat further includes a fine-tuning position, the second seat can be rotated to the fine-tuning position, the limiting hole is located between the fine-tuning position and the storage position, and the number of locking slots is at least two sets. When the locking part is inserted into one set of the locking slots, the second seat is located in the locking position, and when the locking part is inserted into other sets of the locking slots, the second seat is located in the fine-tuning position.

[0015] The aforementioned foldable trolley handle also includes a locking spring, the two ends of which are in contact with the first seat and the locking member, respectively. The locking spring pushes the locking member to move from the unlocked position to the locked position.

[0016] The aforementioned foldable trolley handle also includes an unlock button, which is movably connected to the first seat. The direction of movement of the unlock button is parallel to the axis of rotation of the second seat around the first seat. The unlock button passes through the first seat and contacts the locking member. The unlock button can push the locking member from the locked position to the unlocked position.

[0017] In the aforementioned foldable trolley handle, the first seat is provided with a travel groove, and the second seat is provided with a travel block. The travel block is located in the travel groove and moves within the travel groove through the relative rotation of the second seat and the first seat.

[0018] A children's stroller is also provided, including the aforementioned foldable stroller handle, and further including: a support body and a handle body, wherein the support body is connected to the first seat and the handle body is connected to the second seat.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. When the limit pin extends out of the limit hole, the second seat is restricted from rotating from the working position to the storage position. Under normal working conditions, the limit pin can be controlled to extend out of the limit hole. When storage is required, the limit pin can be controlled to retract into the limit hole to allow the second seat to pass through. This effectively prevents the second seat from automatically rotating from the working position to the storage position due to external force or its own weight, which would cause inconvenience to the user.

[0021] 2. The limiting spring pushes the limiting pin out of the limiting hole, so that the limiting pin always remains in the extended state of the limiting hole without being affected by external force, preventing the limiting pin from automatically retracting into the limiting hole due to external force or its own weight, thus ensuring the safety and reliability of the structure.

[0022] 3. When the second seat rotates from the storage position to the working position, the second seat pushes the limit pin back into the limit hole through the linkage inclined surface. Therefore, when the second seat rotates from the storage position to the working position, the limit pin can automatically retract into the limit hole without manual pressing.

[0023] 4. When the locking element is in the locked position, the locking part is inserted into the locking groove. When the locking element is in the unlocked position, the locking part is separated from the locking groove. During this period, the locking element is always in the positioning groove to achieve locking or unlocking of the second seat and the first seat.

[0024] 5. When the locking part is inserted into one set of locking slots, the second seat is in the locked position. When the locking part is inserted into other sets of locking slots, the second seat is in the fine-adjustment position. Therefore, in addition to the working position and the storage position, the second seat can also be locked in the fine-adjustment position with a relatively small rotation range to accommodate users of different heights and make it more convenient.

[0025] 6. The locking spring pushes the locking element from the unlocked position to the locked position, so that the locking element always remains in the locked position without being affected by external forces, preventing the locking element from returning to the unlocked position due to external forces or its own weight, and ensuring the safety and reliability of the structure.

[0026] 7. The stroke block is located in the stroke groove and moves within the stroke groove through the relative rotation of the second seat and the first seat. The stroke block can contact the side walls at both ends of the stroke groove, thereby limiting the maximum relative rotation range between the second seat and the first seat.

[0046] like Figures 1-8 As shown, a foldable trolley handle includes:

[0047] A first base 100 is provided with a limiting hole 110. The first base 100 includes a working position and a storage position. The limiting hole 110 is located between the working position and the storage position.

[0048] The second seat 200 is rotatably connected to the first seat 100 and can be rotated to the working position or the storage position;

[0049] A limiting pin 300 is movably connected to the limiting hole 110. The limiting pin 300 can extend or retract from the limiting hole 110. When the limiting pin 300 extends out of the limiting hole 110, the second seat 200 is restricted from rotating from the working position to the storage position.

[0050] In this embodiment, when the limiting pin 300 extends out of the limiting hole 110, the second seat 200 is restricted from rotating from the working position to the storage position. Under normal working conditions, the limiting pin 300 can be controlled to extend out of the limiting hole 110, and when storage is required, the limiting pin 300 can be controlled to retract into the limiting hole 110 to allow the second seat 200 to pass through. This effectively prevents the second seat 200 from automatically rotating from the working position to the storage position due to external force or its own weight, thus preventing inconvenience to the user.

[0051] like Figures 1-8 As shown, based on the above embodiment, a limiting spring 400 is also included. The two ends of the limiting spring 400 are in contact with the first seat 100 and the limiting pin 300, respectively. The limiting spring 400 pushes the limiting pin 300 out of the limiting hole 110.

[0052] In this embodiment, the limiting spring 400 pushes the limiting pin 300 out of the limiting hole 110, so that the limiting pin 300 always remains in the state of extending out of the limiting hole 110 without being affected by external forces, preventing the limiting pin 300 from automatically retracting into the limiting hole 110 due to external forces or its own weight, thus ensuring the safety and reliability of the structure.

[0053] like Figures 1-8As shown, based on the above implementation method, the limiting pin 300 is provided with a linkage inclined surface 310. When the second seat 200 rotates from the storage position to the working position, the second seat 200 pushes the limiting pin 300 to retract into the limiting hole 110 through the linkage inclined surface 310.

[0054] In this embodiment, when the second seat 200 rotates from the storage position to the working position, the second seat 200 pushes the limiting pin 300 to retract into the limiting hole 110 through the linkage inclined surface 310. Therefore, when the second seat 200 rotates from the storage position to the working position, the limiting pin 300 can automatically retract into the limiting hole 110 without manual pressing.

[0055] like Figures 1-8 As shown, based on the above embodiment, a locking member 500 is also included. The locking member 500 is movably connected to the first seat 100. When the second seat 200 is in the working position, the locking member 500 is used to lock the second seat 200 and the first seat 100.

[0056] Specifically, the first seat 100 is also provided with a positioning groove 120, and the locking member 500 is always located in the positioning groove 120. The first seat 100 also includes a locking position and an unlocking position. The second seat 200 is provided with a locking groove 210. The locking member 500 is movably connected to the first seat 100 and can be moved to the locking position or the unlocking position. The moving direction of the locking member 500 is parallel to the axis of rotation of the second seat 200 around the first seat 100. The locking member is provided with a locking part 510. When the locking member 500 is in the locking position, the locking part 510 is inserted into the locking groove 210. When the locking member 500 is in the unlocking position, the locking part 510 is separated from the locking groove 210.

[0057] In this embodiment, when the locking member 500 is in the locked position, the locking part 510 is inserted into the locking groove 210, and when the locking member 500 is in the unlocked position, the locking part 510 is separated from the locking groove 210. During this period, the locking member 500 is always located in the positioning groove 120 to achieve locking or unlocking of the second seat 200 and the first seat 100.

[0058] like Figures 1-8As shown, based on the above embodiment, the first seat 100 further includes a fine-tuning position, the second seat 200 is rotatable to the fine-tuning position, the limiting hole 110 is located between the fine-tuning position and the storage position, and the number of locking slots 210 is at least two sets. When the locking part 510 is inserted into one set of locking slots 210, the second seat 200 is located in the locking position, and when the locking part 510 is inserted into other sets of locking slots 210, the second seat 200 is located in the fine-tuning position.

[0059] Specifically, the number of locking units 510 is not specifically limited; it can be one, two, or more.

[0060] Specifically, the number of a set of locking slots 210 is not specifically limited, but mainly corresponds to the number of locking blocks, but the total number of locking slots 210 needs to be greater than the number of locking parts 510.

[0061] In this embodiment, when the locking part 510 is inserted into one of the locking slots 210, the second seat 200 is in the locked position. When the locking part 510 is inserted into other locking slots 210, the second seat 200 is in the fine-tuning position. Therefore, in addition to the working position and the storage position, the second seat 200 can also be locked in the fine-tuning position with a relatively small rotation range to accommodate users of different heights and make it more convenient.

[0062] like Figures 1-8 As shown, based on the above embodiment, a locking spring 600 is also included. The two ends of the locking spring 600 are in contact with the first seat 100 and the locking member 500, respectively. The locking spring 600 pushes the locking member 500 to move from the unlocked position to the locked position.

[0063] In this embodiment, the locking spring 600 pushes the locking member 500 from the unlocked position to the locked position, so that the locking member 500 is always kept in the locked position without being affected by external forces, preventing the locking member 500 from returning to the unlocked position due to external forces or its own gravity, and ensuring the safety and reliability of the structure.

[0064] like Figures 1-8 As shown, based on the above embodiment, an unlock button 700 is also included. The unlock button 700 is movably connected to the first seat 100. The moving direction of the unlock button 700 is parallel to the axis of rotation of the second seat 200 around the first seat 100. The unlock button 700 passes through the first seat 100 and contacts the locking member 500. The unlock button 700 can push the locking member 500 to move from the locked position to the unlocked position.

[0065] In this embodiment, the unlock button 700 can push the locking member 500 from the locked position to the unlocked position, so as to manually keep the locking member 500 in the unlocked position and realize the rotation of the second seat 200.

[0066] like Figures 1-8 As shown, based on the above embodiment, the first seat 100 is provided with a travel groove 130, and the second seat 200 is provided with a travel block 220. The travel block 220 is located in the travel groove 130 and moves within the travel groove 130 through the relative rotation of the second seat 200 and the first seat 100.

[0067] In this embodiment, the stroke block 220 is located in the stroke groove 130 and moves within the stroke groove 130 through the relative rotation of the second seat 200 and the first seat 100. The stroke block 220 can contact the side walls at both ends of the stroke groove 130, thereby limiting the maximum relative rotation range between the second seat 200 and the first seat 100.

[0068] like Figures 1-12 As shown, a children's stroller includes a foldable stroller handle, and further includes a support body 800 and a handle body 900. The support body 800 is connected to the first seat 100, and the handle body 900 is connected to the second seat 200.
