Description

Technical Field

[0001] This utility model relates to the field of children's vehicle technology, specifically a dual-purpose children's vehicle. Background Technology

[0002] Strollers are an important tool for children's daily travel and play, and there are many different types. Currently, strollers on the market, whether they are mainly for pushing or for children to ride and play, often have relatively simple design concepts and functions.

[0003] The primary function of existing children's vehicles is to enable children to move or ride. For example, common children's toy cars typically have four or three wheels supporting them on the ground. These wheels (especially the front wheels, which are usually designed as swivel wheels, and the rear wheels, which can slide in a straight line or lock) allow the children's vehicle to glide freely on the ground, providing children with movement and simple riding fun.

[0004] However, this design has significant limitations. When parents need to secure the stroller in a specific location, such as for safe play or as a fixed play structure, the current solution is usually simply to lock the rear wheels. The disadvantage of this locking mechanism is:

[0005] 1. Limited and Single Functionality: Once the rear wheels are locked, the stroller completely loses its mobility. At this point, the stroller can only provide a simple riding function, and its use and play functions in a fixed state are greatly limited. For example, children cannot engage in play activities that require slight back-and-forth or side-to-side swaying on a locked stroller, which greatly reduces the stroller's fun and practicality.

[0006] 2. Poor play experience: For active children, a completely stationary stroller quickly loses its appeal. When a stroller is completely still, the child's play space and methods are severely limited, making it impossible to engage in interactive games that require slight movement or rotation. This significantly reduces the stroller's play function and may even bore the child, causing them to lose interest in playing continuously.

[0007] 3. Lack of innovation and flexibility: Existing technology fails to provide a design for a stroller that maintains a certain level of interactivity or play potential even in a fixed mode. Indoors or specific play areas, parents often want a stroller to provide a relatively stable and interactive play platform without being completely fixed and rigid. Existing strollers clearly cannot meet this need, therefore further improvements are necessary. Utility Model Content

[0008] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a dual-purpose stroller that is simple in structure, low in manufacturing cost, and not only has the traditional sliding and moving function, but also provides a more flexible, interactive and stable fixing method when fixing is required, thereby expanding the usage scenarios of the stroller and enhancing children's play experience.

[0009] The objective of this utility model is achieved in the following way: a dual-purpose children's stroller, comprising a frame, two front wheels mounted on the front bottom of the frame, and two rear wheels mounted on the rear bottom of the frame, wherein the front and rear wheels together support the frame on the ground, wherein:

[0010] The front wheels are swivel wheels;

[0011] The rear wheel is mounted on the tilting frame, and the frame is provided with a hinge seat. The tilting frame is mounted in the hinge seat by a hinge shaft in a swing-type hinge manner. A locking device is provided between the hinge seat and the tilting frame. The locking device locks the tilting frame in a positive sliding position or a side fixed position.

[0012] Furthermore: one side of the rear wheel is provided with an axle connected to the tilting frame, and the other side of the rear wheel is provided with an anti-slip surface. When the tilting frame is in the side fixed position, the anti-slip surface is supported on the ground.

[0013] Furthermore, the anti-slip surface is provided with several outwardly protruding anti-slip particles.

[0014] Furthermore, the locking device is a locking pin that is slidably mounted on the hinge seat. Correspondingly, the flipping frame is provided with a positive locking hole and a side locking hole. The locking pin is inserted into the positive locking hole to lock the flipping frame in the positive sliding position, or inserted into the side locking hole to lock the flipping frame in the side fixed position.

[0015] Furthermore: the locking pin is connected to a drive handle, and a reset push spring is provided between the drive handle and the hinge seat. The reset push spring pushes the locking pin to move in the direction of the flipping frame.

[0016] Furthermore, the bottom of the hinge seat is provided with an indicator cavity, and the drive handle is provided with a push block that extends into the indicator cavity.

[0017] Furthermore: There are two of each of the above-ground locking holes and the side locking holes, which are symmetrically distributed on both sides of the hinge shaft. The above-ground locking holes and the side locking holes are distributed at an interval of ° along the rotation direction of the flipping frame.

[0018] Furthermore: the hinge seat is provided with a hinge hole, the hinge shaft is installed in the hinge hole, the outer side of the hinge hole is provided with a guide hole, and the locking pin passes through the guide hole and is inserted into the positive locking hole or the side locking hole.

[0019] Furthermore, the bottom of the frame is provided with a recessed receiving area, and the rear wheel is installed in the receiving area.

[0020] Furthermore: a decorative disc is provided on the front wheel, and correspondingly, a decorative ring is installed at the bottom of the frame. The interior of the decorative ring is hollow to form a rotating area, and the decorative disc is installed in the rotating area.

[0021] The beneficial effects of this utility model are: 1. Simple structure, low manufacturing cost, and improved market competitiveness.

[0022] 2. When the rear wheel is in the positive sliding position, the stroller can slide and move freely and smoothly on the ground, just like a traditional stroller, relying on the forward rolling of the front and rear wheels for support. This meets the needs of parents pushing their children or children riding and sliding, maintaining the basic transportation function of the stroller.

[0023] 3. When the stroller needs to be relatively fixed and used for children's play, the flip frame is locked in the "side fixed position" by the locking device. At this time, the anti-slip surface on the side of the rear wheel supports the ground, and its direction is perpendicular to the sliding direction of the frame, thereby preventing the stroller from sliding in a wide range of straight lines.

[0024] 4. In the side-mounted fixed position, because the front wheels of the stroller are swivel wheels, the stroller can no longer move freely in a straight line, but it can still rotate within a small range around its own axis. This "rotating in place" characteristic cleverly limits the stroller's range of motion, preventing it from sliding out of the safe area, while avoiding the stiffness and boredom of a traditional stroller when completely locked. It provides children with a relatively stable yet still interactive play platform, meeting their need for safe play within a limited space.

[0025] 5. The integrated design of the tilting frame, hinge base, and locking device makes switching between the two modes simple and intuitive. Users can easily switch modes by simply inserting or removing the locking pin, improving the user experience. Meanwhile, the rear wheels are directly mounted on the tilting frame, resulting in a compact structure without adding any complex components. Attached Figure Description

[0034] The present invention will be further described in detail below with reference to the accompanying drawings. A dual-purpose children's stroller includes a frame 1, two front wheels 2 are mounted on the front bottom of the frame 1, and two rear wheels 3 are mounted on the rear bottom of the frame 1. The front wheels 2 and the rear wheels 3 together support the frame 1 on the ground, wherein:

[0035] The front wheel 2 is a swivel wheel;

[0036] The rear wheel 3 is mounted on the tilting frame 4. The frame 1 is provided with a hinge seat 5. The tilting frame 4 is mounted in the hinge seat 5 by a hinge shaft 41. A locking device is provided between the hinge seat 5 and the tilting frame 4. The locking device locks the tilting frame 4 in a positive sliding position or a side fixed position.

[0037] In this embodiment, the stroller is supported by a frame 1, with the front wheel 2 and rear wheel 3 at the bottom jointly supporting it on the ground. The front wheel 2 is designed as a swivel wheel, allowing it to rotate freely around a vertical axis, thus enabling the stroller to steer flexibly. The key innovation lies in the fact that the rear wheel 3 is not directly fixed to the frame, but rather mounted on a swingable tilting frame 4. This tilting frame 4 is hinged to a hinge seat 5 on the frame 1 via a hinge pin 41, allowing the rear wheel 3 to swing together with the tilting frame 4. A locking device is provided between the hinge seat 5 and the tilting frame 4, which securely fixes the tilting frame 4 in two preset structural positions: one called the "positive sliding position" and the other called the "lateral fixed position." These two positions determine the posture of the rear wheel 3 relative to the ground and the frame 1, thereby affecting the overall movement pattern of the stroller.

[0038] In this embodiment, the stroller can switch from a traditional "sliding movement mode" to an innovative "playing in place mode" through a swingable flip frame and a precise locking device. This design breaks through the limitations of existing strollers with only one function, making the stroller not just a means of transportation, but also a safe and interactive play platform, greatly expanding the product's usage scenarios and value.

[0039] In one embodiment: one side of the rear wheel 3 is provided with an axle 31 connected to the tilting frame 4, and the other side of the rear wheel 3 is provided with an anti-slip surface 32. When the tilting frame 4 is in the side fixed position, the anti-slip surface 32 is supported on the ground.

[0040] In this embodiment, the rear wheel 3 is connected to the tilting frame 4 via an axle 31. Crucially, in addition to its regular rolling surface, the rear wheel 3 also has a specially designed anti-slip surface 32 on its side. When the tilting frame 4 is locked in the "side-fixed position" by the locking device, the rear wheel 3 swings, causing its normal rolling surface to detach from the ground, and instead, this anti-slip side directly contacts the ground and supports the stroller. This contact method effectively increases the friction between the rear wheel and the ground, thereby suppressing large-scale sliding of the stroller.

[0041] In this embodiment, by allowing the anti-slip surface of the rear wheels to directly support the ground, the stroller effectively prevents accidental slippage or displacement when used as a fixed play platform, providing children with a safer and more reliable play environment. This overcomes the shortcomings of traditional strollers where wobbling or slight slippage may still occur even after the wheels are simply locked.

[0042] In one embodiment, the anti-slip surface 32 is provided with a plurality of outwardly protruding anti-slip particles 33.

[0043] In this embodiment, several outwardly protruding anti-slip particles 33 are additionally provided on the surface of the anti-slip surface 32. When the anti-slip surface 32 is supported on the ground, these anti-slip particles 33 directly contact the ground, forming more contact points and greater friction.

[0044] The anti-slip particles 33 further enhance the friction performance and anti-slip effect of the anti-slip surface 32. Even on relatively smooth surfaces, it provides more reliable grip, minimizing unnecessary movement of the stroller in the "side-mounted position," making the stroller more secure and improving children's safety while playing.

[0045] In one embodiment: the locking device is a locking pin 6 that is slidably mounted on the hinge seat 5. Correspondingly, the flip frame 4 is provided with a positive locking hole 42 and a side locking hole 43. The locking pin 6 is inserted into the positive locking hole 42 to lock the flip frame 4 in the positive sliding position, or inserted into the side locking hole 43 to lock the flip frame 4 in the side fixed position.

[0046] In this embodiment, the core component of the locking device is a locking pin 6 that is slidably mounted on the hinge seat 5. The flip frame 4 has two corresponding holes in specific positions: a positive locking hole 42 for locking the "positive sliding position" and a side locking hole 43 for locking the "side fixed position". The user operates the device to slide the locking pin 6 into one of the corresponding locking holes. When the locking pin 6 engages with the locking hole, the flip frame 4 is securely fixed in the preset position represented by that hole, thus placing the stroller in the corresponding movement mode.

[0047] This locking method, which uses a locking pin and a locking hole, has the advantages of simple structure, intuitive operation, and reliable locking. Through a rigid mechanical connection, it ensures that the tilting frame 4 will not swing or disengage unexpectedly in the selected mode, thus guaranteeing the stability and safety of the stroller in both operating modes. This clear physical locking mechanism provides users with a clear and reliable mode switching experience.

[0048] In one embodiment: the locking pin 6 is connected to a drive handle 62, and a return spring is provided between the drive handle 62 and the hinge seat 5. The return spring pushes the locking pin 6 to move continuously toward the flipping frame 4. The spring continuously applies a pushing force, causing the locking pin 6 to move toward the flipping frame 4. When the user pulls the drive handle 62, the locking pin 6 disengages from the lock hole; when the user releases the handle 62, the spring force of the return spring automatically pushes the locking pin 6 back to its original position, finding and inserting it into the nearest aligned lock hole.

[0049] This spring-reset design greatly simplifies user operation and improves the convenience and security of the locking mechanism. It enables automatic return and locking of the locking pin, avoiding potential safety hazards caused by users forgetting to push the pin into place. This "foolproof" design ensures that the locking pin reliably locks after each mode switch, improving the product's user-friendliness and reliability.

[0050] In one embodiment: the bottom of the hinge seat 5 is provided with an indicator cavity 51, and the drive handle 62 is provided with a push block 63 extending into the indicator cavity 51.

[0051] In this embodiment: when the locking pin 6 is in the locked state, i.e. inserted into the keyhole, the position of the push block 63 in the indicator cavity 51 will be different from that in the unlocked state. The user can determine whether the locking pin is fully locked by observing the display status of the push block 63.

[0052] The combination of the indicator cavity and the push block provides a clear visual feedback mechanism. Users do not need to check whether the stroller is locked by touch or shaking; they can quickly and accurately determine the status of the locking device simply by looking. This greatly improves the convenience and safety of operation, effectively avoiding potential dangers caused by misjudging the locking status, such as moving or playing with the stroller when it is not fully locked.

[0053] In one embodiment: two of each of the positive locking holes 42 and the side locking holes 43 are provided, symmetrically distributed on both sides of the hinge shaft 41, and the positive locking holes 42 and the side locking holes 43 are distributed at 90° intervals along the rotation direction of the flipping frame 4.

[0054] First, the center locking hole 42 and the side locking hole 43 are arranged in pairs and symmetrically distributed on both sides of the hinge pin 41, which provides two locking points to enhance stability. More importantly, the center locking hole 42 and the side locking hole 43 are spaced 90° apart along the rotation direction of the tilting frame 4. This ensures that the tilting frame 4 rotates exactly 90° when it swings from one locking position to another.

[0055] In this embodiment, the precise 90° angle arrangement is key to efficiently switching between the two functional modes of "orthodox sliding" and "lateral fixation." It ensures that the rear wheel 3 can achieve a precise functional transition when switching from the normal rolling orthodox posture to the lateral support posture. The symmetrical distribution further enhances the mechanical balance and stability during locking, reducing swaying and ensuring the stroller's safety in both modes.

[0056] In one embodiment: the hinge seat 5 is provided with a hinge hole 52, the hinge shaft 41 is installed in the hinge hole 52, the hinge hole 52 is provided with a guide hole 53 on the outside, and the locking pin 6 passes through the guide hole 53 and is inserted into the positive locking hole 42 or the side locking hole 43.

[0057] In this embodiment, the guide hole 53 provides precise path guidance for the movement of the locking pin 6. It ensures that the locking pin 6 maintains correct alignment when entering and exiting the keyhole, effectively preventing jamming, skewness, or misalignment. This improves the smoothness and reliability of the locking mechanism, extends the service life of the components, and ensures the accuracy and stability of each locking action.

[0058] In one embodiment, the bottom of the frame 1 has a recessed receiving area 11, within which the rear wheel 3 is mounted. This recessed mounting design makes the overall structure of the stroller more compact and streamlined, reducing protruding external parts and potentially lowering the risk of impacts. Secondly, mounting the rear wheel within the receiving area provides some protection for the rear wheel, reducing damage from external impacts. Furthermore, this design helps optimize the stroller's center of gravity, potentially improving its overall stability during movement and stationary states.

[0059] In one embodiment: a decorative disc 21 is provided on the front wheel 2, and correspondingly, a decorative ring 12 is installed at the bottom of the frame 1. The interior of the decorative ring 12 is hollow to form a rotating area 13, and the decorative disc 21 is installed in the rotating area 13.

[0060] Therefore, when the stroller moves, the front wheel 2 rotates, causing the decorative disc 21 on it to rotate within the rotating area 13 of the decorative ring 12. This can protect the front wheel bearing area to some extent, preventing foreign objects from getting caught in the front wheel axle.

[0061] In summary, the dual-purpose stroller provided by this utility model has the core working principle of enabling convenient switching between the two main functional states of "free sliding" and "playing in place" through an innovative rear wheel mode switching mechanism.

[0062] Specifically: The stroller is supported by two swivel casters at the front and two rear wheels 3 mounted on the flip frame 4 at the rear. The swivel casters give the stroller the ability to turn flexibly, while the unique design of the rear wheels 3 is the key to achieving dual-purpose functionality. The concave receiving area 11 at the bottom of the frame 1 makes the rear wheels 3 more compact, improving the overall aesthetics and potential protection.

[0063] When the user needs to move the stroller in a traditional manner, the locking device is operated so that the locking pin 6 is inserted into the positive locking hole 42 on the tilting frame 4, locking the tilting frame 4 in the "positive sliding position". In this position, the normal rolling surface of the rear wheel 3 is in contact with the ground, and its direction is consistent with the direction of travel of the stroller. At this time, the front wheel and the rear wheel work together in the forward rolling direction, and the stroller can freely move forward, backward and turn flexibly on the ground, meeting the needs of parents pushing the child or the child riding and sliding, and maintaining the basic transportation function of the stroller.

[0064] When the user needs to secure the stroller, for example, for children to play in place, the locking device is operated so that the locking pin 6 is inserted into the side locking hole 43 on the flip frame 4, locking the flip frame 4 in the "side fixed position". The center locking hole 42 and the side locking hole 43 are distributed at 90° intervals along the rotation direction of the flip frame 4, ensuring precise angles when switching modes. In this position, the normal rolling surface of the rear wheel 3 is out of contact with the ground, and is instead supported by the anti-slip surface 32 provided on its side. The anti-slip surface 32 is further provided with several outwardly protruding anti-slip particles 33 to maximize the friction with the ground, thereby effectively preventing the stroller from making large-scale straight-line movements or accidental sliding.

[0065] Although the rear wheel 3 is "fixed" and restricted from straight-line sliding, the front wheel 2 of the stroller remains a swivel wheel. This unique combination allows the stroller to rotate or circle within a limited range in place, centered on a fixed axis, usually the rear wheel support point or its vicinity. This "limited range of motion but still rotatable" characteristic satisfies the need for the stroller to be secured in a safe area while providing children with an interactive play experience, avoiding the stiffness and boredom of traditional strollers that are completely locked.

[0066] The mode switching relies on the coordinated action of the hinge base 5, the flip frame 4, and the locking device. The core of the locking device is the locking pin 6, which is slidably mounted on the hinge base 5. It is operated via a connected drive handle 62 and automatically locked in place by a return spring. The guide hole 53 within the hinge base 5 provides precise guidance for the movement of the locking pin 6, ensuring smooth insertion into the oriented locking hole 42 or the lateral locking hole 43. The push block 63 on the drive handle 62 extends into the indicator cavity 51 at the bottom of the hinge base 5, providing intuitive visual feedback so that the user can clearly determine the locking status of the locking pin, further enhancing the convenience and security of operation.

[0067] In summary, this dual-purpose stroller, through its ingenious rear wheel structure, precise locking system, and omnidirectional front wheels, successfully achieves a seamless switch between "free sliding" and "stationary rotation and fixed play," greatly enhancing the stroller's practicality, playability, and safety. Therefore, it can be widely promoted and used.
