Description

Technical Field

[0001] This invention relates to the field of children's vehicle technology, and more particularly to a children's stroller. Background Technology

[0002] Currently, strollers are an essential tool for infant and toddler care. Especially with the increasingly fast pace of life, strollers are indispensable for children's growth in order to save on childcare costs.

[0003] With the development of smart technology, strollers are also becoming increasingly intelligent. Existing smart strollers allow control of the rear wheels via buttons on a push rod, enabling functions such as forward movement, rotation, and height adjustment. These strollers also feature rotating seats for easier parental supervision. However, for smart strollers with rotating seats, the control buttons are typically located on the push rod for ease of operation, connected to the rear wheels via wires. These wires are usually housed within the stroller frame to prevent damage and potential electrical leakage. In contrast, the rotating connection between the seat and rear wheel support assembly makes the internal wires susceptible to damage. Rotation could also cause the control buttons to lose connection with the rear wheel support assembly, preventing the rear wheels from moving. Furthermore, accidental activation of the control buttons when the stroller is not being pushed could pose a safety hazard to the child.

[0004] Therefore, there is an urgent need to design a children's stroller to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide a stroller that ensures the connection of the upper and lower electrical structures after the rotary switch mechanism is rotated, thereby improving the safety of the internal structure and extending the service life of the stroller.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] Strollers, including:

[0008] A rear wheel bracket assembly includes a first bracket and a rear wheel, wherein the rear wheel is mounted on the first bracket;

[0009] The seat assembly includes a second bracket and a control switch, the control switch being disposed on the second bracket; and

[0010] A rotary switch mechanism includes a first rotary switch assembly and a second rotary switch assembly. The first rotary switch assembly is fixedly connected to the first bracket and electrically connected to the rear wheel. The second rotary switch assembly is fixedly connected to the second bracket and electrically connected to the control switch. The second rotary switch assembly is rotatably connected to the first rotary switch assembly so that the second rotary switch assembly can be connected or disconnected from the first rotary switch assembly.

[0011] Optionally, the first rotary switch assembly described above includes:

[0012] A first switch base, which is fixedly connected to the first bracket and rotatably connected to the second rotary switch assembly; and

[0013] A first connector and a second connector are symmetrically arranged along the central axis of the first switch base. Both the first connector and the second connector are fixedly connected to the first switch base. Both the first connector and the second connector can be electrically connected to the rear wheel. The second rotary switch assembly can selectively abut against either the first connector or the second connector.

[0014] Optionally, the first connector is electrically connected to the second connector, and one of the first connector and the second connector is electrically connected to the rear wheel.

[0015] Optionally, both the first connector and the second connector are electrically connected to the rear wheel.

[0016] Optionally, multiple first connectors and multiple second connectors are provided, with multiple first connectors arranged side by side and multiple second connectors arranged side by side.

[0017] Optionally, the second rotary switch assembly described above includes:

[0018] The second switch holder is fixedly connected to the second bracket and rotatably connected to the first rotary switch assembly; and

[0019] The third connector is fixed to the second switch base and electrically connected to the control switch, and can selectively abut against the first rotary switch assembly.

[0020] Optionally, multiple third connectors are provided, and multiple third connectors are arranged side by side.

[0021] Optionally, the rotary switch mechanism further includes a rotating shaft, which is connected to the first rotary switch assembly and the second rotary switch assembly, and the second rotary switch assembly is rotatable along the rotating shaft.

[0022] Optionally, the rotary switch mechanism includes a locking member disposed between the first rotary switch assembly and the second rotary switch assembly, which can lock or release the first rotary switch assembly and the second rotary switch assembly.

[0023] Optionally, the rotary switch mechanism described above is arranged symmetrically along its central axis.

[0024] The beneficial effects of this invention are:

[0025] This invention provides a stroller that replaces the rotating mechanism with a rotary switch mechanism. This allows the control switch on the seat assembly and the rear wheels on the rear wheel support assembly to be connected via the rotary switch mechanism. Specifically, the connection between the control switch and the rear wheels is achieved through the rotational connection of the first and second rotary switch assemblies, while simultaneously ensuring the rotation of the rotary switch mechanism. This prevents wear on the wires, improves the safety of the internal structure, and thus extends the lifespan of the stroller. Furthermore, when the seat assembly and the rear wheel support assembly rotate to a preset angle, the rotary switch mechanism disconnects, separating the control switch from the rear wheels. This prevents accidental activation of the control switch when the stroller is not being pushed, further enhancing the stroller's safety. Attached Figure Description

[0041] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0042] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0043] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0044] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. 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 the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0045] like Figures 1 to 4 As shown, this embodiment provides a stroller, which includes a rear wheel support assembly 10, a seat assembly, and a rotary switch mechanism 30. The rear wheel support assembly 10 includes a first support 11 and a rear wheel 12, with the rear wheel 12 mounted on the first support 11. The seat assembly includes a second support 21 and a control switch, with the control switch mounted on the second support 21. The rotary switch mechanism 30 includes a first rotary switch assembly 31 and a second rotary switch assembly 32. The first rotary switch assembly 31 is fixedly connected to the first support 11 and electrically connected to the rear wheel 12, enabling a conductive connection between the first rotary switch assembly 31 and the rear wheel 12. The second rotary switch assembly 32 is fixedly connected to the second support 21 and electrically connected to the control switch, enabling a conductive connection between the second rotary switch assembly 32 and the control switch. The second rotary switch assembly 32 is rotatably connected to the first rotary switch assembly 31, allowing the second rotary switch assembly 32 to be switched on or off with the first rotary switch assembly 31, thereby enabling a switch to be switched on or off between the control switch and the rear wheel 12.

[0046] In this embodiment of the stroller, by replacing the rotating mechanism in the existing structure with a rotary switch mechanism 30, the control switch on the seat assembly and the rear wheel 12 on the rear wheel bracket assembly 10 can be connected through the rotary switch mechanism 30. That is, the connection between the control switch and the rear wheel 12 can be achieved by rotating the first rotary switch assembly 31 and the second rotary switch assembly 32, avoiding wear of the connecting wires, improving the safety of the internal structure, and thus increasing the service life of the stroller. At the same time, it ensures the rotation of the rotary switch mechanism 30, so that the rear wheel bracket assembly 10 and the seat assembly can rotate 360°. Furthermore, when the seat assembly and the rear wheel support assembly 10 are rotated by a preset angle (in this embodiment, the preset angle is greater than 0° and less than 180°, and greater than 180° and less than 360°), the rotary switch mechanism 30 is disconnected, thereby disconnecting the control switch from the rear wheel 12. That is, the control switch can only be connected to the rear wheel 12 when the child is sitting behind the seat facing the person pushing or facing the person pushing, thus avoiding accidental activation of the control switch when people are not pushing the stroller, and improving the safety of the stroller.

[0047] Optionally, the electrical connection between the first rotary switch assembly 31 and the rear wheel 12, and the electrical connection between the second rotary switch assembly 32 and the control switch are both connected by wires, and the wires are set inside the first bracket 11 and the second bracket 21 to avoid exposure and the risk of leakage, and also to ensure that the wires are not damaged.

[0048] In this embodiment, as Figure 3 As shown, the rear wheel 12 is rotatably mounted on the first bracket 11, enabling the rear wheel 12 to move forward, backward, and rotate, thereby allowing the stroller to move forward, backward, and turn. Furthermore, the first bracket 11 is a telescopic bracket, allowing the rear wheel 12 to be raised or lowered. The above functions and structures are mature technologies in the field and will not be elaborated further. Optionally, two rear wheels 12 can be provided to improve the stability of the stroller during operation.

[0049] Furthermore, such as Figure 4 As shown, the second bracket 21 includes a push rod (not shown) and a seat bracket. The seat bracket is rotatably connected to the rear wheel bracket assembly 10, meaning the second rotary switch assembly 32 is mounted on the seat bracket. A seat can be placed on the seat bracket, allowing a child to be seated inside. The push rod is connected to the seat bracket, facilitating pushing the stroller. The control switch is located on the push rod for easy operation. It is understood that the control switch controls the movement, rotation, and extension / retraction of the rear wheels 12 using existing control structures, such as microcontrollers, which will not be elaborated upon here.

[0050] In this embodiment, as Figure 5 and Figure 6As shown, the first rotary switch assembly 31 includes a first switch base 311, a first connector 312, and a second connector 313. The first switch base 311 is fixedly connected to the first bracket 11 and rotatably connected to the second rotary switch assembly 32. The first connector 312 and the second connector 313 are both fixedly connected to the first switch base 311, and the first connector 312 and the second connector 313 are symmetrically arranged along the central axis of the first switch base 311, such that the included angle between the first connector 312 and the second connector 313 is 180°. Furthermore, both the first connector 312 and the second connector 313 can be electrically connected to the rear wheel 12. The second rotary switch assembly 32 can selectively abut against the first connector 312 or the second connector 313, so that the second rotary switch assembly 32 is connected to the rear wheel 12. When the second rotary switch assembly 32 is in a preset position, i.e., rotated 0°, 180° and 360°, the second rotary switch assembly 32 can abut against the first connector 312 or the second connector 313. At this time, the second rotary switch assembly 32 is connected to the first connector 312 or the second connector 313, thereby realizing the connection between the control switch and the rear wheel 12, so that the drive of the rear wheel 12 can be controlled by operating the control switch.

[0051] Optionally, the first switch base 311 and the first bracket 11 are integrally formed, which facilitates manufacturing and reduces the manufacturing steps of the stroller.

[0052] Optionally, in this embodiment, the first connector 312 is electrically connected to the second connector 313, and one of the first connector 312 and the second connector 313 is electrically connected to the rear wheel 12. This allows both the first connector 312 and the second connector 313 to be electrically connected to the rear wheel 12. Consequently, when the second rotary switch assembly 32 is connected to the first connector 312 or to the second connector 313, the control switch can be connected to the rear wheel 12.

[0053] In another alternative embodiment, both the first connector 312 and the second connector 313 are electrically connected to the rear wheel 12, which can also enable both the first connector 312 and the second connector 313 to be electrically connected to the rear wheel 12. This allows the control switch to be connected to the rear wheel 12 when the second rotary switch assembly 32 is connected to the first connector 312 or to the second connector 313.

[0054] Preferably, multiple first connectors 312 and multiple second connectors 313 are provided. Multiple first connectors 312 are arranged side by side to form a first connection group, and multiple second connectors 313 are arranged side by side to form a second connection group. That is, the first connection group and the second connection group are symmetrically arranged along the central axis of the first switch base 311, which increases the contact area of ​​the electrical connection between the first rotary switch assembly 31 and the second rotary switch assembly 32, avoids problems such as poor contact, and improves the stability of the electrical connection between the first rotary switch assembly 31 and the second rotary switch assembly 32.

[0055] Furthermore, such as Figure 5 and Figure 7 As shown, the second rotary switch assembly 32 includes a second switch base 321 and a third connector 322. The second switch base 321 is fixedly connected to the second bracket 21 and rotatably connected to the first rotary switch assembly 31. The third connector 322 is fixedly connected to the second switch base 321 and electrically connected to the control switch. The third connector 322 can selectively abut against the first rotary switch assembly 31. When the third connector 322 is in a preset position, i.e., when the third connector 322 rotates 0°, 180°, and 360°, the third connector 322 can abut against the first connector 312 or the second connector 313. At this time, the third connector 322 is connected to the first connector 312 or the second connector 313, thereby enabling the control switch to connect with the rear wheel 12, so that the drive of the rear wheel 12 can be controlled by operating the control switch. Optionally, the second switch base 321 and the second bracket 21 are integrally formed, which is convenient to manufacture and reduces the manufacturing steps of the stroller.

[0056] Preferably, multiple third connectors 322 are provided, and the multiple third connectors 322 are arranged side by side to form a third connection group, which increases the area of ​​electrical connection between the first rotary switch assembly 31 and the second rotary switch assembly 32, avoids problems such as poor contact, and improves the stability of electrical connection between the first rotary switch assembly 31 and the second rotary switch assembly 32.

[0057] Optionally, such as Figure 8 As shown, the first connector 312, the second connector 313 and the third connector 322 are all U-shaped contact pieces, and the top of the U-shape of the third connector 322 is also provided with a protrusion 3221 to facilitate contact and connection with the first connector 312 and the second connector 313.

[0058] In this embodiment, as Figure 5As shown, the rotary switch mechanism 30 further includes a rotating shaft 33, which is connected to the first rotary switch assembly 31 and the second rotary switch assembly 32. The second rotary switch assembly 32 rotates along the rotating shaft 33, thereby ensuring that the first rotary switch assembly 31 and the second rotary switch assembly 32 are coaxially arranged, avoiding misalignment that could lead to poor contact and improving the connection stability between the two. Specifically, the rotating shaft 33 is a pin, with a protrusion at one end and the other end passing through the first rotary switch assembly 31 and the second rotary switch assembly 32, and fixed with an external latch. It is understood that in other embodiments, the rotating shaft 33 can be a bolt with an external thread at one end, the middle of which is a smooth rod with an external thread at only one end. This bolt passes through the first rotary switch assembly 31 and the second rotary switch assembly 32, and is fixed with a nut. Furthermore, the rotating shaft 33 can also be other structures that can achieve the above functions, and no specific limitation is made here.

[0059] Furthermore, the rotary switch mechanism 30 includes a locking member disposed between the first rotary switch assembly 31 and the second rotary switch assembly 32. The locking member can lock or release the first rotary switch assembly 31 and the second rotary switch assembly 32. When the second rotary switch assembly 32 is in a preset position, it can be locked, which improves the stability between the seat and the rear wheel support assembly 10 and improves the stability of the stroller.

[0060] Optionally, the rotary switch mechanism 30 is symmetrically arranged along its central axis, which facilitates manufacturing and makes the rotary switch mechanism 30 more aesthetically pleasing.

[0061] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
