[0002] Existing stroller mounting seats are typically fixed to the frame and cannot be adjusted in position according to usage needs. When the mounting seat is not in use, the exposed seat not only affects aesthetics but may also pose a safety hazard. Therefore, a stroller mounting seat mechanism that can switch between a used and concealed state is needed. Summary of the Invention
[0003] The purpose of this application is to provide a dual-position adjustment mechanism for a stroller mounting seat. Through an innovative structural design, the mechanism enables convenient switching between the use state and the hidden state of the mounting seat, thereby improving aesthetics and safety.
[0004] The technical solution of this application is: a dual-position adjustment mechanism for a stroller mounting seat, including a frame and a mounting seat. The frame has a fixing member, and the mounting seat is rotatably connected to the fixing member through a movable pin. The movable pin can move axially relative to the fixing member and is provided with an elastic member between it and the fixing member. The fixing member has a boss, and the mounting seat has a use slot and a hidden slot for locking the boss.
[0005] When the boss is locked into the use slot, the mounting base is in the extended use state;
[0006] When the boss is locked into the hidden slot, the mounting base is in a retracted and hidden state;
[0007] The mounting base can switch states through axial displacement for unlocking, rotation for adjustment, and automatic reset for locking.
[0008] As a preferred technical solution, the axial movement distance of the movable pin is greater than the mating depth between the boss and the working slot and the hidden slot.
[0009] As a preferred technical solution, the slot for use and the slot for concealment are located on the same circumference of the mounting base, but at different angles.
[0010] As a preferred technical solution, a first limiting block is formed on the fixing member, and a second limiting block is provided on the frame; when the mounting seat is in use, the first limiting block and the second limiting block respectively restrict the rotation of the mounting seat in two directions.
[0011] As a preferred technical solution, the thickness distance of the first limiting block is greater than the axial movement distance of the movable pin; the thickness distance of the second limiting block is less than the axial movement distance of the movable pin.
[0012] As a preferred technical solution, the end of the movable pin is provided with an anti-detachment structure.
[0013] As a preferred technical solution, the elastic element is a reset spring, whose preload causes the boss to form a self-locking engagement with the working slot and the hidden slot.
[0014] Compared with the prior art, this application has the following advantages:
[0015] 1. This application achieves convenient switching between the use state and the hidden state of the mounting seat through the cooperation of the movable pin and the elastic element and the engagement of the boss with different slots; in the hidden state, the mounting seat can avoid the risk of exposure, avoid the space occupation or bump risk of the protruding structure, and improve the overall aesthetics and safety of the stroller.

[0033] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the described embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. It is understood that, without conflict, some technical means of the various embodiments described herein can be substituted for or combined with each other.
[0034] In the description of this application and the claims, the terms "first," "second," etc., are used only to distinguish the described objects and have no sequential or technical meaning. Therefore, objects specified with "first," "second," etc., may explicitly or implicitly include one or more of those objects. Furthermore, the words "one" or "a" do not indicate a quantity limitation, but rather indicate the presence of at least one, while "multiple" indicates not less than two.
[0035] In the description of this application and the claims, the terms "connection," "installation," "fixation," and "reception," unless otherwise specified, should be interpreted broadly. For example, "connection" can mean a separate connection or an integral connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean a non-detachable connection or a detachable connection.

[0036] In the description of this application and the claims, if terms such as "above," "below," or "horizontal" indicate orientation or positional relationships based on the orientation or positional relationships shown in the drawings, they are only for the purpose of clearly and simply describing this application, and do not indicate or imply that the elements referred to must have a specific orientation or be constructed and operated in a specific orientation. These directional terms are relative concepts used for relative description and clarification, and may change accordingly depending on the orientation of the components in the drawings. For example, if the device in the drawings is flipped, an element described as "below" other elements will be positioned "above" other elements.
[0037] In the description of this application specification and claims, the term "if" is generally interchangeable with "when," "at," "in response to determination," or "in response to detection," depending on the context.
[0038] In the description of this application and the claims, if there is a "direction" of motion, including motion with a directional component, the term "in direction" is not necessarily understood as motion only in that one direction. Those skilled in the art can understand the specific meaning of the aforementioned terms in this application according to the specific circumstances.
[0039] like Figures 1 to 8 As shown, a dual-position adjustment mechanism for a stroller mounting seat includes a frame 1 and a mounting seat 2. A fixing member 3 is fixedly mounted on the frame 1. The mounting seat 2 is rotatably connected to the fixing member 3 via a movable pin 4. The movable pin 4 can move axially relative to the fixing member 3 and is provided with an elastic member 5 between it and the fixing member 3. The fixing member 3 is provided with a boss 301, and the mounting seat 2 is provided with a use slot 201 and a hidden slot 202 into which the boss 301 can be locked.
[0040] When the boss 301 is locked into the use slot 201, the mounting base 2 is in the extended use state;
[0041] When the boss 301 is locked into the hidden slot 202, the mounting base 2 is in a retracted and hidden state;
[0042] The mounting base 2 can switch states through axial displacement unlocking, rotation adjustment, and automatic reset locking.
[0043] In this embodiment, the axial movement distance of the movable pin 4 is greater than the mating depth between the boss 301 and the working slot 201 and the hidden slot 202. This design ensures that the boss 301 can completely disengage from the current slot, avoiding jamming during switching; at the same time, it provides sufficient axial movement margin, making the rotation smooth and interference-free. When the elastic element 5 resets, the boss 301 can accurately engage with the target slot, improving operational reliability.
[0044] In this embodiment, the used slot 201 and the hidden slot 202 are located on the same circumference of the mounting base 2, but at different angles. Although only one boss 301 design is shown in the embodiment figure, its slot position or the number of bosses can be adjusted as needed. For example, the slot position can be adjusted according to the tilt angle of the mounting rod of the mounting base 2 on the frame 1, and the number of bosses 301 can be adjusted according to the load-bearing requirements to further improve stability and reliability.
[0045] In this embodiment, a first limiting block 302 is formed on the fixing member 3, and a second limiting block 6 is provided on the frame 1. When the mounting base 2 is in use, the first limiting block 302 and the second limiting block 6 respectively restrict the rotation of the mounting base 2 in two directions. The thickness of the first limiting block 302 is greater than the axial movement distance of the movable pin 4; the thickness of the second limiting block 6 is less than the axial movement distance of the movable pin 4. This design achieves dual protection through limiting blocks of different thicknesses: the first limiting block 302 and the second limiting block 6 ensure that the mounting base 2 is stable and does not loosen when in use, while the second limiting block 6 allows smooth rotation during switching operations. The precise matching of the axial movement distances prevents accidental unlocking and ensures flexibility in switching between hidden states, improving security and ease of operation.
[0046] In this embodiment, the end of the movable pin 4 is provided with an anti-detachment structure. The anti-detachment structure can effectively prevent the movable pin 4 from accidentally disengaging during frequent operation, ensuring the reliability of the mechanism for long-term use; at the same time, it avoids the risk of parts loss and improves product safety.
[0047] In this embodiment, the elastic element 5 is a reset spring, and its preload causes the boss 301 to form a self-locking engagement with the use slot 201 and the hidden slot 202.
[0048] The working principle of this application is as follows:
[0049] This application achieves position locking by engaging the boss 301 with the use slot 201 or the hidden slot 202, so that the mounting base 2 remains fixed in both the use state and the hidden state, preventing accidental rotation.
[0050] like Figures 3 to 8 As shown, switch from active to hidden state:
[0051] Step 1, Axial displacement unlocking: Pull the mounting base 2 to move the movable pin 4 axially, the boss 301 exits the slot 201 and the lock is released.
[0052] Step 2, Rotation Adjustment: Rotate the mounting base 2 until the hidden slot 202 is aligned with the boss 301.
[0053] Step 3, Automatic Reset Locking: After releasing the tension, the elastic element 5 pushes the mounting base 2 back to its original position, causing the boss 301 to engage with the hidden slot 202, completing the state switch.
[0054] Reverse switching (from hidden state to active state): Repeat the same operation, rotate the mounting base 2 to align the active slot 201 with the boss 301 and reset the lock.
[0055] This application utilizes an innovative linkage design of axial displacement unlocking, rotational adjustment, and automatic reset locking, allowing for quick switching between the active and hidden states with simple operation, requiring no additional tools or complex steps. Its simple structure and intuitive operation, combined with high stability and safety, make it particularly suitable for strollers requiring frequent position adjustments. In the hidden state, the mounting base 2 avoids the risk of exposure, preventing protruding structures from occupying space or causing bumps, thus improving the overall aesthetics and safety of the stroller.
