They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0037] like Figures 1-5 As shown, this embodiment provides a trolley carrier adjustment device, including a mounting base 1, a joint 2, an angle adjustment mechanism, and a sliding adjustment mechanism. The mounting base 1 is used to be fixedly connected to the vehicle frame. The joint 2 includes a rotating connecting part 21 and a sliding connecting part 22 connected to each other. The rotating connecting part 21 is rotatably connected to the mounting base 1 to adjust the tilt angle of the carrier 100. An angle adjustment mechanism is provided between the rotating connecting part 21 and the mounting base 1. The angle adjustment mechanism is movably connected to the rotating connecting part 21 and can engage with the mounting base 1 to prevent the joint 2 from rotating with the mounting base 1, thereby locking the tilt angle of the carrier 100.

[0038] The sliding connection part 22 is used to slidably connect with the vehicle 100 so as to adjust the height of the vehicle 100; a sliding adjustment mechanism is provided between the vehicle 100 and the joint 2, the sliding adjustment mechanism is movably connected to the sliding connection part 22 and can be engaged with the vehicle 100 to lock the height of the vehicle 100.

[0039] By combining the angle adjustment mechanism and the sliding adjustment mechanism, the flexibility of the vehicle 100's angle and height adjustment is greatly improved, making it suitable for various usage scenarios (such as increasing the angle of the vehicle 100 when traveling to make it easier for children to sit up, decreasing the angle of the vehicle 100 when putting children to sleep so they can lie down, raising the position of the vehicle 100 when dining to match the height of the table, and lowering the height of the vehicle 100 to lower the center of gravity when traversing complex terrain, etc.), thus improving the practicality of the stroller and enhancing the user experience.

[0040] In some optional embodiments, the angle adjustment mechanism includes a first locking component 3 and a first connecting component. The first connecting component is movably connected to the rotating connecting part 21 and has a first locking position that engages with the card holder 1 and a first unlocking position that releases the engagement. The first locking component 3 is connected to the first connecting component and is used to drive the first connecting component to move between the first locking position and the first unlocking position. When the first locking component 3 drives the first connecting component to the angle unlocking position, the joint 2 can rotate relative to the card holder 1, thereby flexibly adjusting the tilt angle of the carrier 100.

[0041] like Figure 2 and Figure 3As shown, in some optional embodiments, the first locking component 3 includes a first elastic element 31, the first connecting component includes an angle engaging gear 4, a first gear groove 211 is provided in the rotating connecting part 21, and a second gear groove 11 corresponding to the first gear groove 211 is provided on the side of the card seat 1 near the joint 2. The angle engaging gear 4 is engaged in the first gear groove 211 and can move axially along the first gear groove 211. The first elastic element 31 is disposed between the angle engaging gear 4 and the rotating connecting part 21. The first elastic element 31 is configured to make the angle engaging gear 4 engage in the first gear groove 211 and the second gear groove 11 at the same time, so that the card seat 1 and the joint 2 stop rotating, thereby locking the tilt angle of the carrier 100.

[0042] In some optional embodiments, a first limiting shaft 212 is provided at the center of the first gear groove 211, and a second limiting shaft 14 that is adapted to the shape and size of the first limiting shaft 212 is provided at the center of the second gear groove 11. The angle-engaging gear 4 can be sleeved on the first limiting shaft 212 and the second limiting shaft 14. The first limiting shaft 212 and the second limiting shaft 14 provide a guiding function for the sliding of the angle-engaging gear 4.

[0043] In some optional embodiments, the first locking component 3 further includes an angle adjustment button 32, which is axially movably connected to the card holder 1 along the second gear groove 11. One end of the angle adjustment button 32 can pass through the inner wall of the second gear groove 11 and abut against the angle engaging gear 4. The angle adjustment button 32 is configured to push the angle engaging gear 4 into the first gear groove 211. When the angle engaging gear 4 is fully engaged in the first gear groove 211, the joint 2 can rotate relative to the card holder 1, thereby realizing the angle adjustment of the carrier 100.

[0044] In some optional embodiments, a first mounting groove 12 is provided on the side of the card holder 1 away from the joint 2, and the angle adjustment button 32 is slidably disposed in the first mounting groove 12 along the axial direction of the second gear groove 11. The angle adjustment button 32 and the card holder 1 form a compact and fitted embedded structure design, which not only effectively reduces the overall volume of the stroller carrier adjustment device, but also avoids space waste caused by the protrusion of components, thereby significantly improving the neatness and aesthetics of the device appearance. At the same time, a sliding fit relationship is formed between the inner wall surface of the first mounting groove 12 and the outer wall surface of the angle adjustment button 32. This fit relationship provides precise guidance for the reciprocating movement of the angle adjustment button 32 along the axial direction of the second gear groove 11, ensuring the stability of the button's movement trajectory. On the other hand, the bottom of the first mounting groove 12 and the two side walls can provide all-round support for the angle adjustment button 32, so that when it is subjected to external operating force, the force can be evenly distributed to the main structure of the card holder 1, thereby effectively improving the load capacity of the angle adjustment button 32 and making the stroller more reliable and durable in practical applications.

[0045] like Figure 3 As shown, in some optional embodiments, the angle adjustment button 32 includes a button body 321 and an elastic claw 322 disposed circumferentially on the button body 321. The mounting base 1 has a limiting groove 13 communicating with the first mounting groove 12, and a stepped first engaging portion is formed between the limiting groove 13 and the first mounting groove 12. The first engaging portion can engage with the elastic claw 322. The deformation capability of the elastic claw 322 enables quick press-type installation without additional fasteners, simplifying the assembly process and reducing costs. Simultaneously, the embedded structure design makes the components compact and fit well, improving space utilization and aesthetics. Furthermore, the engagement of the first engaging portion with the elastic claw 322 provides a limit to the axial movement of the angle adjustment button 32 along the second gear groove 11, preventing the angle adjustment button 32 from disengaging from the first mounting groove 12 during sliding, further enhancing the reliability of the structure and the smoothness of operation.

[0046] The elastic pawl 322 is used to abut against the inner wall of the second gear groove 11 and the angle engaging gear 4, pushing the angle engaging gear 4 to move into the first gear groove 211.

[0047] In some optional embodiments, the button body 321 is provided with at least three elastic claws 322 evenly spaced around the circumference. By applying force at multiple points, the stability of the locking structure is improved, avoiding the risk of skewing or loosening caused by force at a single point. This ensures that the angle adjustment button 32 remains circumferentially balanced after installation, provides stronger anti-torsion capability, maintains accurate trajectory when the button is pressed to adjust the angle, and avoids shaking that affects the operating feel.

[0048] In some optional embodiments, the end of the elastic claw 322 away from the button body 321 is provided with a second guide slope 3221. The second guide slope 3221 gradually slopes away from the button body 321 from the circumference of the angle adjustment button 32 towards the center. When the angle adjustment button 32 is installed, the second guide slope 3221 abuts against the inner wall of the first mounting groove 12, applying pressure to the angle adjustment button 32. The inner wall of the first mounting groove 12 generates a force on the second guide slope 3221 toward the axis of the first mounting groove 12, causing the elastic claw 322 to deform toward the axis of the first mounting groove 12, so that the elastic claw 322 can slide into the limiting groove 13 and engage with the first engaging part.

[0049] In some alternative embodiments, the button body 321 is recessed from the circumference toward the center into the first mounting groove 12, which makes it easier for the user to press the button body 321 with their finger to install or press the angle adjustment button 32, which facilitates the adjustment of the carrier 100 angle and improves the operating feel.

[0050] like Figure 5As shown, in some optional embodiments, the sliding adjustment mechanism includes a second locking component 5 and a second connecting component. The second connecting component is movably connected to the sliding connecting portion 22 and has a second locking position that engages with the carrier 100 and a second unlocking position that releases the engagement. The second locking component 5 is connected to the second connecting component and is used to drive the second connecting component to move between the second locking position and the second unlocking position. When the second locking component 5 drives the second connecting component to the second unlocking position, the joint 2 can slide relative to the carrier 100, thereby adjusting the height of the carrier 100.

[0051] In some optional embodiments, the second locking component 5 includes a second elastic element 51, and the second connecting component includes a carrier locking spring 6. The carrier 100 has a plurality of snap-fit ​​holes 101 spaced apart along its own extension direction. The carrier locking spring 6 is movably connected to the sliding connecting part 22, and the second elastic element 51 is disposed between the carrier locking spring 6 and the sliding connecting part 22. The second elastic element 51 is configured to drive the carrier locking spring 6 to snap into any snap-fit ​​hole 101 so that the joint 2 is relatively fixed to the carrier 100, thereby locking the height position of the carrier 100.

[0052] In some optional embodiments, the sliding connection 22 is provided with a second mounting groove 221, and the carrier locking spring 6 is slidably disposed in the second mounting groove 221. The second mounting groove 221 provides guidance and support for the movement of the carrier locking spring 6 toward or away from the locking hole 101, which is beneficial to improving the stability of the height locking of the carrier 100 and also beneficial to improving the load capacity of the sliding adjustment mechanism.

[0053] In some optional embodiments, the second locking component 5 further includes a rope 52 and a sliding block 53. The sliding block 53 is movably disposed within the carrier 100 along the extending direction of the carrier 100. One end of the rope 52 is connected to the sliding block 53 to drive the sliding block 53 to move along the extending direction of the carrier 100. The sliding block 53 is provided with guide structures corresponding one-to-one with the locking holes 101. When the rope 52 drives the sliding block 53 to move along the extending direction of the carrier 100, the carrier locking spring 6 can move away from the locking hole 101 under the action of the corresponding guide structure. When the carrier locking spring 6 is completely disengaged from the locking hole 101, the joint 2 can slide relative to the carrier 100, thereby realizing the height adjustment of the carrier 100.

[0054] In some optional embodiments, the sliding block 53 has a first guide groove 531 corresponding to the locking hole 101 for accommodating the vehicle locking spring 6. The end of the first guide groove 531 away from the rope 52 has a first guide slope 532. The first guide slope 532 slides with the vehicle locking spring 6 to form the above-mentioned guide structure. When the rope 52 drives the sliding block 53 to move along the extension direction of the vehicle 100, each first guide groove 531 is misaligned with the corresponding locking hole 101. The vehicle locking spring 6 moves away from the locking hole 101 under the push of the corresponding first guide slope 532, and the sliding block 53 blocks each locking hole 101 so that the vehicle locking spring 6 cannot enter all locking holes 101, thereby allowing the vehicle 100 to slide freely relative to the sliding connection part 22 of the joint 2 to achieve the height adjustment of the vehicle 100.

[0055] In some optional embodiments, the second locking component 5 further includes a third elastic element 55 disposed between the sliding block 53 and the carrier 100. The third elastic element 55 is configured to drive the sliding block 53 to reset, so that each first guide groove 531 communicates with the corresponding snap-fit ​​hole 101. After the height adjustment of the carrier 100 is completed, the rope 52 is released, and the third elastic element 55 drives the sliding block 53 to reset, so that the first guide groove 531 communicates with the snap-fit ​​hole 101 one by one. The second elastic element 51 drives the carrier locking spring 6 to snap into the snap-fit ​​hole 101 and the first guide groove 531 corresponding to the height, so as to realize the relative locking between the joint 2 and the carrier 100.

[0056] like Figure 1 and Figure 5 As shown, in some optional embodiments, the second locking component 5 further includes a sliding unlock button 54, which is movably connected to the carrier 100 and is connected to the rope 52 in a transmission manner. It can drive the rope 52 to move away from the sliding block 53, so that the rope 52 can drive the sliding block 53 to slide, thereby causing the first guide slope 532 to push the carrier locking spring 6 to move away from the snap-fit ​​hole 101.

[0057] Furthermore, the sliding unlock button 54 is located at the top of the vehicle 100, close to the operator's position, making it easy to press the sliding unlock button 54 and improving the convenience of adjusting the height of the vehicle 100.

[0058] Specifically, the second locking component 5 further includes a mounting sleeve 56 and at least two fixing blocks 57. The fixing blocks 57 are used to connect the rope body 52. ​​The at least two fixing blocks 57 are arranged opposite to each other in the mounting sleeve 56 along the length direction of the mounting sleeve 56. The sliding unlock button 54 is slidably connected to the mounting sleeve 56 along the height direction of the mounting sleeve 56. The first end of the sliding unlock button 54 is provided with a second guide groove 541. The width of the second guide groove 541 gradually decreases from the first end of the sliding unlock button towards the second end. The two side walls of the second guide groove 541 are respectively slidably engaged with at least one fixing block 57.

[0059] By pressing the sliding unlock button 54, the sliding unlock button 54 slides into the mounting sleeve 56, which drives at least two fixing blocks 57 to move closer to each other, thereby moving the rope 52 away from the sliding block 53. At the same time, the rope 52 moves the sliding block 53, causing the vehicle locking spring 6 to move away from the snap-fit ​​hole 101. After the vehicle 100 height adjustment is completed, the sliding unlock button 54 is released, and the sliding block 53 can be reset under the action of the third elastic element 55, so that each first guide groove 531 is connected to the corresponding snap-fit ​​hole 101, and the vehicle locking spring 6 snaps into the corresponding snap-fit ​​hole 101 under the action of the second elastic element 51.

[0060] In some optional embodiments, the second locking component 5 further includes a fourth elastic element 58 disposed between the two fixing blocks 57 for driving at least two fixing blocks 57 away from each other, thereby pushing the fixing blocks 57 and the rope 52 to reset, which helps to improve the efficiency and accuracy of the height locking of the vehicle 100.

[0061] It is easy to understand that, in order to improve the stability of the connection between the vehicle 100 and the frame, a card seat 1 is provided on both sides of the frame, and a joint 2 is provided on both sides of the vehicle 100. Each joint 2 is connected to the vehicle 100 through a sliding adjustment mechanism. The second locking component 5 is provided with two fixing blocks 57, which can be connected to a rope 52 respectively, thereby realizing the simultaneous control of the sliding adjustment mechanisms on both sides.

[0062] In addition, the two ends of the mounting sleeve 56 are connected to the interior of the carrier 100, and the rope 52 is threaded through the carrier 100, which can improve the uniformity and aesthetics of the stroller's appearance, as well as improve the stroller's safety and eliminate potential safety hazards for children.

[0063] In some optional embodiments, a stroller is also provided, including a frame, a carrier 100, and a stroller carrier adjustment device as described in any of the above embodiments. The bracket 1 is fixedly connected to the frame, and the sliding connection portion 22 of the joint 2 is slidably connected to the carrier 100. By applying the stroller carrier adjustment device, the flexibility of the angle and height adjustment of the carrier 100 is greatly improved, enabling it to adapt to various usage scenarios, enhancing the practicality of the stroller, and improving the user experience.

[0064] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
