Description

Technical Field

[0001] This application relates to the field of stroller technology, and in particular to a stroller push handle switching mechanism for horizontal and vertical pushing. Background Technology

[0002] The stroller in the present technology is a tool vehicle designed to facilitate the outdoor activities of infants. It is a means of transportation for babies to go out and an essential item for taking care of infants.

[0003] Most existing strollers have push handles mounted on the top of the push bar. The grip part of these push handles is basically a horizontal bar extending from left to right. Therefore, when pushing, whether with one hand or two hands, the pusher can only hold it horizontally, which is not very comfortable for pushers who push for a long time. Summary of the Invention

[0004] The purpose of this application is to provide a mechanism for switching between horizontal and vertical push of a stroller handlebar. This mechanism has a novel and simple structure and can switch between horizontal and vertical push of the handlebar, thereby improving the comfort of pushing the stroller.

[0005] The technical solution of this application is: a stroller push handle horizontal and vertical push switching mechanism, including a push rod and a push handle. The push rod has a first mounting seat at the top center, and the push handle has a second mounting seat rotatably connected to the first mounting seat. A first locking mechanism that can lock the push handle in a horizontal position and a second locking mechanism that can lock the push handle in a vertical position are provided between the first mounting seat and the second mounting seat.

[0006] As a preferred technical solution, the first locking mechanism includes a first locking member installed in a first mounting groove of the first mounting base and retractable relative to it, a first reset member disposed between the first mounting groove and the first locking member, a first locking groove disposed on the second mounting base and into which the first locking member is locked, and a first unlocking member disposed on the second mounting base and capable of pushing the first locking member out of the first locking groove.

[0007] The second mounting base has a third mounting groove that communicates with the first locking groove. The first unlocking member is slidably disposed in the third mounting groove and a third reset member is disposed between the two. The outer end of the first unlocking member protrudes from the second mounting base to form a first operating part.

[0008] As a preferred technical solution, the second locking mechanism includes a second locking member installed in the second mounting groove of the first mounting base and retractable relative to it, a second reset member disposed between the second mounting groove and the second locking member, a second locking groove disposed on the second mounting base and into which the second locking member is locked, and a second unlocking member disposed on the second mounting base and capable of pushing the second locking member out of the second locking groove.

[0009] The second mounting base has a fourth mounting groove communicating with the second locking groove. The second unlocking member is slidably disposed in the fourth mounting groove, and the outer end of the second unlocking member protrudes from the second mounting base to form a second operating part.

[0010] As a preferred technical solution, the second mounting base has a limiting post corresponding to the second unlocking member, and the side of the second unlocking member has a limiting groove. The limiting groove can be positioned in the locking position and the unlocking position of the second unlocking member by tightly fitting with the limiting post.

[0011] As a preferred technical solution, the second locking groove and the second unlocking component are two sets, symmetrically arranged on both sides of the second mounting base; the first locking groove and the first unlocking component are one set, and are arranged at a 90-degree interval from the second locking groove and the second unlocking component on both sides. This design allows the second locking mechanism to automatically lock after the first locking mechanism is released, regardless of whether the push handle is turned 90 degrees to the left or right, making operation simple and convenient.

[0012] As a preferred technical solution, the push handle is in the shape of a flat ring, and the side away from the push rod is the grip rod for pushing.

[0013] As a preferred technical solution, a grip sleeve is provided at the middle position of the grip bar. This grip sleeve preferably employs an anti-slip design, such as an anti-slip texture or raised / lowered structure on the surface, and its material is preferably an elastic or soft material to improve hand comfort.

[0014] For ease of assembly, the second mounting base is preferably formed by joining left and right base bodies together; the first mounting base is preferably formed by assembling multiple components. Since the splicing structure is diverse and is not the main protected part of this application, no specific restrictions or descriptions are made here.

[0015] Compared with the prior art, this application has the following advantages: the structure of this application is novel and simple, and it can realize the switching between horizontal and vertical pushing of the handle, thereby improving the comfort when pushing. Attached Figure Description

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.

[0036] 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.

[0037] 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.

[0038] like Figures 1 to 8 As shown, a stroller push handle horizontal / vertical push switching mechanism includes a push rod 1 and a push handle 2. The push rod 1 has a first mounting seat 3 at the top center. The push handle 2 has a second mounting seat 4 rotatably connected to the first mounting seat 3. A first locking mechanism 5 that can lock the push handle 2 in a horizontal position and a second locking mechanism 6 that can lock the push handle 2 in a vertical position are provided between the first mounting seat 3 and the second mounting seat 4.

[0039] In this embodiment, the first locking mechanism 5 includes a first locking member 502 installed in the first mounting groove 501 of the first mounting base 3 and retractable relative to it, a first resetting member 503 disposed between the first mounting groove 501 and the first locking member 502, a first locking groove 504 disposed on the second mounting base 4 and into which the first locking member 502 is locked, and a first unlocking member 505 disposed on the second mounting base 4 and capable of pushing the first locking member 502 out of the first locking groove 504;

[0040] The second mounting base 2 has a third mounting groove 506 that communicates with the first locking groove 505. The first unlocking member 505 is slidably disposed in the third mounting groove 506 and a third reset member 507 is disposed between the two. The outer end of the first unlocking member 505 protrudes from the second mounting base 4 to form a first operating part.

[0041] In this embodiment, the second locking mechanism 6 includes a second locking member 602 installed in the second mounting groove 601 of the first mounting base 3 and retractable relative to it, a second resetting member 603 disposed between the second mounting groove 601 and the second locking member 602, a second locking groove 604 disposed on the second mounting base 4 and into which the second locking member 602 is locked, and a second unlocking member 605 disposed on the second mounting base 4 and capable of pushing the second locking member 602 out of the second locking groove 604;

[0042] The second mounting base 4 has a fourth mounting groove 506 that communicates with the second locking groove 604. The second unlocking member 605 is slidably disposed in the fourth mounting groove 606, and the outer end of the second unlocking member 605 protrudes from the second mounting base 4 to form a second operating part.

[0043] In this embodiment, the second mounting base 4 has a limiting post 401 corresponding to the second unlocking member 605, and the side of the second unlocking member 605 has a limiting groove 6051. The limiting groove 6051 can be positioned in the locking position and unlocking position of the second unlocking member 605 by tightly fitting with the limiting post 401.

[0044] In this embodiment, the second locking groove 604 and the second unlocking member 605 are two sets, symmetrically arranged on both sides of the second mounting base 4; the first locking groove 504 and the first unlocking member 505 are one set, and are arranged at a 90-degree interval from the second locking groove 604 and the second unlocking member 605 on both sides. This design allows for automatic locking of the second locking mechanism 6 after the first locking mechanism 5 is released, regardless of whether the push handle is turned 90 degrees to the left or right, making operation simple and convenient.

[0045] In this embodiment, the push handle 2 is in the shape of a flat ring, with the side furthest from the push rod 1 serving as a grip rod 201 for pushing. A grip sleeve 202 is positioned in the middle of the grip rod 201. This grip sleeve 202 preferably employs an anti-slip design, such as an anti-slip texture or raised surface, and is preferably made of an elastic or soft material to improve hand comfort.

[0046] When the push handle 2 is in the lateral position, the person pushing the cart can hold the handle 201 laterally with both hands or with one hand to push it horizontally.

[0047] When the push handle 2 is in the vertical position, the person pushing the cart can hold the handle 201 vertically with one hand to push it vertically.

[0048] For ease of assembly, the second mounting base 4 is preferably formed by joining the left and right base bodies together; the first mounting base 2 is preferably formed by assembling multiple components. Since the splicing structure is diverse and is not the main protected part of this application, no specific restrictions or descriptions are made here.

[0049] The working principle of this application is as follows:

[0050] If, in the initial state, the push handle 2 is in the horizontal position, the first locking mechanism 5 is in the locked state, that is, the first locking member 502 is locked into the first locking groove 504, and the push handle 2 is locked in the horizontal position and cannot rotate. At the same time, the second locking member 602 of the second locking mechanism 6 is misaligned with the second locking groove 604, so the second locking mechanism 6 is in the unlocked state.

[0051] When push handle 2 needs to be switched from a horizontal to a vertical position, pressing the first unlocking member 505 will push the first locking member 502 out of the first locking groove 504, thus releasing the lock of the first locking mechanism 5. At this time, turning the push handle 90 degrees to the left or right will cause the second locking member 602 of the second locking mechanism 6 to be directly aligned with one of the second locking grooves 604. Under the reset action of the second reset member 603, the second locking member 602 will lock into the second locking groove 604, achieving automatic locking of the second locking mechanism 6 and keeping push handle 2 in the vertical position. Simultaneously, the first locking member 502 of the first locking mechanism 5 and the first locking groove 504 are misaligned, thus keeping the first locking mechanism 5 in the unlocked state.

[0052] When the push handle 2 needs to be switched from a vertical to a horizontal position, pressing the second unlocking member 605 causes its limiting groove 6051 to slide from the locked position to the unlocked position through a tight fit with the limiting post 401 and remain in the unlocked position. At this time, the second unlocking member 605 moves down, pushing the second locking member 602 out of the second locking groove 604, so that the second locking mechanism 6 is in the unlocked state. Then, rotating the push handle 2 in the opposite direction to return it to the flat position, the first locking member 502 locks into the first locking groove 504 under the reset action of the first reset member 503, and the first locking mechanism 5 locks again, keeping the push handle 2 in the horizontal position. Similarly, the second locking member 602 and the second locking groove 604 of the second locking mechanism 6 re-enter the misaligned state, so the second locking mechanism 6 remains in the unlocked state.

[0053] This application features a novel and simple structure that allows for switching between horizontal and vertical pushing of the push handle 2, improving comfort during pushing.
