Description

Technical Field

[0001] This utility model belongs to the field of stroller technology, and specifically refers to a new type of stroller. Background Technology

[0002] In recent years, strollers have become an essential item for families with children. Various types of strollers have appeared on the market, such as the Chinese patent CN222116901U, which mainly consists of a frame and a luggage compartment. Users can install the luggage compartment onto the frame, allowing the child to not only sit on the stroller but also use it as a luggage cart, achieving a multi-functional effect. However, because the guardrail on the frame consists of a first guardrail and a second guardrail, with the second guardrail only fixed to the frame via a snap-fit, the overall stability of the guardrail is poor. The guardrail is prone to moving up and down under external force. When a child is placed inside the guardrail, when the stroller travels over bumpy roads, the child's arms inevitably press down on the second guardrail, causing the entire guardrail to tilt downwards. When the child leans back, their upper body loses the support of the guardrail, greatly reducing its protective function. The child could easily fall off the seat, posing a safety risk. Summary of the Invention

[0003] The purpose of this invention is to provide a new type of stroller with a simple structure, good guardrail stability, and a guardrail body that cannot tilt downwards when a child's arm presses down on it, ensuring that the guardrail body remains in the upper part of the child's body and thus guaranteeing the child's safety.

[0004] The purpose of this utility model is achieved as follows:

[0005] A novel stroller includes a frame and rolling wheels located at the bottom of the frame. The frame has a seat and a pull rod. Above the seat is a guardrail assembly, which includes a guardrail body and a guardrail fixing rod. The guardrail body is ring-shaped, and a connecting component is provided between the ring-shaped guardrail body and the pull rod. The guardrail fixing rod is located between the seat and the guardrail, and its top end is connected to the guardrail body, while its bottom end is connected to the seat.

[0006] Furthermore, the bottom end of the guardrail fixing rod is detachably connected to the seat cushion, and the connecting assembly is detachably connected to the pull rod.

[0007] Furthermore, the seat cushion is provided with a insertion groove, and the bottom end of the guardrail fixing rod is provided with an insertion part and a left elastic insertion plate. The insertion part and the left elastic insertion plate are arranged adjacent to each other, and a left deformation space is formed between the inner sides of the insertion part and the left elastic insertion plate. The insertion part and the left elastic insertion plate are both located in the insertion groove. A left snap-fit ​​hole is provided on the inner wall of the left side of the insertion groove, and a left snap-fit ​​protrusion is provided on the outer side of the left elastic insertion plate. The left snap-fit ​​protrusion is located in the left snap-fit ​​hole and snaps into the seat cushion, thereby preventing the insertion part from disengaging from the insertion groove.

[0008] Furthermore, the bottom end of the guardrail fixing rod is also provided with a right elastic insertion plate. The left and right elastic insertion plates are symmetrically arranged. The insertion part is located between the left and right elastic insertion plates. A right deformation space is formed between the inner side of the right elastic insertion plate and the insertion part. The right elastic insertion plate is located in the insertion groove. A right snap-fit ​​hole is opened on the inner wall of the right side of the insertion groove. A right snap-fit ​​protrusion is provided on the outer side of the right elastic insertion plate. The right snap-fit ​​protrusion is located in the right snap-fit ​​hole and snaps into the cushion, thereby preventing the insertion part from disengaging from the insertion groove.

[0009] Furthermore, the surfaces of the right and left snap-fit ​​protrusions are arc-shaped.

[0010] Furthermore, the guardrail body is provided with a first connector, which is rotatably sleeved on the guardrail body. The first connector is provided with a fixing part, and a fixing groove is provided on the fixing part. The top end of the guardrail fixing rod is located in the fixing groove and connected to the fixing part.

[0011] Furthermore, the connecting assembly includes a second connector and a trigger. The second connector is connected to the guardrail body and has a connecting portion. The trigger is hinged to one side of the connecting portion. After the trigger is driven to rotate, the inner side of the trigger will contact the other side of the connecting portion. At this time, an installation space is formed between the trigger and the connecting portion, and the pull rod can be located within the installation space. The other side of the connecting portion has a latching protrusion, and the inner side of the trigger has a latching groove. The latching protrusion can be located in the latching groove and engage with the trigger, thereby preventing the pull rod from leaving the installation space.

[0012] Furthermore, the second connector is rotatably sleeved on the guardrail body.

[0013] Furthermore, the seat cushion is provided with a soft pad, the pull rod is fitted with a handle, the handle is located above the guardrail body, and the handle is provided with a hook.

[0014] Furthermore, the frame is provided with a housing, which is located below the seat and connected to the seat.

The rolling wheels are located at the bottom of the frame body, and the bottom of the auxiliary frame is provided with auxiliary wheels.

[0015] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0016] This utility model belongs to the field of stroller technology, specifically referring to a new type of stroller, including a frame and rolling wheels at the bottom of the frame. A pull rod is provided on the frame, allowing the user to move the frame by pulling the rod, facilitating the movement of the stroller. The frame also has a seat for the child to sit on. A guardrail assembly is located above the seat, so that when the child is sitting on the seat, the guardrail assembly is positioned around the child's body. The guardrail assembly consists of a guardrail body and a guardrail fixing rod. The guardrail body is ring-shaped, and a connecting component is provided between the ring-shaped guardrail body and the pull rod, allowing the guardrail body to be fixedly connected to the pull rod. The child sitting on the seat is within the guardrail body, which provides protection and prevents the child from falling off. Compared to guardrails on existing strollers on the market, the overall stability of this guardrail is poor; when a child is placed inside the guardrail, the stroller may experience bumps or jolting. When children are on the road, their arms inevitably press down on the guardrail, causing the entire guardrail to tilt downwards. When the child leans back, their upper body loses the support of the guardrail, greatly reducing its protective function and potentially causing them to fall off the seat, endangering their safety. This invention addresses this issue by using a guardrail fixing rod located between the seat and the guardrail. The top of the fixing rod connects to the main body of the guardrail, and the bottom connects to the seat, thus securing the main body of the guardrail. When a child's arm presses down on the guardrail, the fixing rod provides support and fixation, preventing the guardrail from tilting downwards and reducing its protective function. This ensures that the main body of the guardrail remains positioned above the child's body, preventing the upper body from losing support when the child leans back and thus ensuring the child's safety.

[0040] The present invention will be further described below with reference to specific embodiments:

[0041] This utility model belongs to the field of stroller technology, specifically referring to a new type of stroller, including a frame 34 and rolling wheels 3 set at the bottom of the frame 34. The frame 34 is equipped with a pull rod 2, allowing the user to move the frame 34 by pulling the pull rod 2, facilitating the movement of the stroller. The frame 34 also has a seat 7, allowing the child to sit on the seat 7. Above the seat 7 is a guardrail assembly 8, so that when the child sits on the seat 7, the guardrail assembly 8 is positioned around the child's body. The guardrail assembly 8 consists of a guardrail body 9 and a guardrail fixing rod 10. The guardrail body 9 is circular, and a connecting component 11 is provided between the circular guardrail body 9 and the pull rod 2. The connecting component 11 allows the guardrail body 9 to be fixedly connected to the pull rod 2. When a child sitting on the seat 7 is inside the guardrail body 9, the guardrail body 9 can play a protective role, preventing the child from falling off the seat 7. Compared with the guardrails on strollers currently on the market, its overall stability is poor. When a child is placed on the guardrail... When strollers travel over bumpy sections, children's arms inevitably press down on the guardrail, causing the entire guardrail to tilt downwards. As the child leans back, their upper body loses the support of the guardrail, significantly reducing its protective function and potentially causing them to fall off the seat, posing a safety risk. This invention addresses this by using a guardrail fixing rod 10 located between the seat cushion 7 and the guardrail itself. The top of the fixing rod 10 is connected to the guardrail body 9, and the bottom of the fixing rod 10 is connected to the seat cushion 7. This secures the main body 9 of the guardrail. When a child's arm presses down on the main body 9, the guardrail fixing rod 10 provides support and fixation, preventing the main body 9 from tilting downwards and reducing its protective function. This ensures that the main body 9 remains positioned above the child's body, preventing the upper part of the child's body from losing support when leaning backwards. This prevents the child from falling off the seat cushion 7 and ensures the child's safety.

[0042] Preferably, the bottom end of the guardrail fixing rod 10 is detachably connected to the seat cushion 7, and the connecting component 11 is detachably connected to the pull rod 2; thus, the user can choose whether to remove the guardrail component 8 from the pull rod 2 according to their actual needs, which can meet the actual needs of different users, reduce the space occupied by the stroller, and facilitate the storage of the stroller.

[0043] Preferably, the seat cushion 7 has a insertion groove 12, and the bottom end of the guardrail fixing rod 10 has an insertion part 13 and a left elastic insertion plate 14. The insertion part 13 and the left elastic insertion plate 14 are arranged adjacent to each other, and a left deformation space 15 is formed between the inner surfaces of the insertion part 13 and the left elastic insertion plate 14. The insertion part 13 and the left elastic insertion plate 14 are both located in the insertion groove 12. The inner wall on the left side of the insertion groove 12 has a left locking hole 16, and the outer surface of the left elastic insertion plate 14 has a left locking protrusion 17. The left locking protrusion 17 is located in the left locking hole 16 and locks into the seat cushion, thereby restricting insertion. The connector 13 disengages from the insertion slot 12. When the user wants to install the guardrail fixing rod 10 onto the seat cushion 7, the user can align the insertion part 13 at the bottom of the guardrail fixing rod 10 and the left elastic insertion plate 14 with the insertion slot 12 on the seat cushion 7. A left deformation space 15 is formed between the inner side of the left elastic insertion plate 14 and the insertion part 13, and the left elastic insertion plate 14 can deform to a certain extent. When the user pushes the insertion part 13 and the left elastic insertion plate 14 toward the insertion slot 12, the left snap-fit ​​protrusion 17 on the outer side of the left elastic insertion plate 14 will abut against the opening of the insertion slot 12. At this time, the user continues to press down. After the guardrail fixing rod 10 is installed, the left elastic insertion plate 14 will deform and move towards the left deformation space 15, so that the left elastic insertion plate 14 and the insertion part 13 enter the insertion groove 12. Since there is a left locking hole 16 on the inner wall of the left side of the insertion groove 12, when the left elastic insertion plate 14 enters the insertion groove 12, the left elastic insertion plate 14 will automatically reset, so that the left locking protrusion 17 on the outer side of the left elastic insertion plate 14 enters the left locking hole 16 and locks with the cushion, thereby preventing the insertion part 13 from disengaging from the insertion groove 12. Finally, the guardrail fixing rod 10 is fixedly installed on the cushion part 7. When the user wants to remove the guardrail fixing rod When the guardrail fixing rod 10 is removed from the seat cushion 7, the user can pull the guardrail fixing rod 10 upwards. At this time, the left elastic insertion plate 14 at the bottom of the guardrail fixing rod 10 will move inwards under the action of external force, so that the left snap-fit ​​protrusion 17 on the left elastic insertion plate 14 will disengage from the left snap-fit ​​hole 16. At this time, the insertion part 13 and the left elastic insertion plate 14 can be disengaged from the insertion groove 12, thereby completing the separation and disassembly of the guardrail fixing rod 10 from the seat cushion 7. This method of installing and disassembling the guardrail fixing rod 10 is simple in structure, allowing the user to quickly complete the installation and disassembly of the guardrail fixing rod 10, making it convenient for the user to use.

[0044] Preferably, the bottom end of the guardrail fixing rod 10 is further provided with a right elastic insertion plate 18. The left elastic insertion plate 14 and the right elastic insertion plate 18 are symmetrically arranged. The insertion part 13 is located between the left elastic insertion plate 14 and the right elastic insertion plate 18, and a right deformation space 19 is formed between the inner side of the right elastic insertion plate 18 and the insertion part 13. The right elastic insertion plate 18 is located in the insertion groove 12. A right snap-fit ​​hole 20 is opened on the inner wall of the right side of the insertion groove 12. A right snap-fit ​​protrusion 21 is provided on the outer side of the right elastic insertion plate 18. The right snap-fit ​​protrusion 21 is located in the right snap-fit ​​hole 20 and snaps into the cushion, thereby restricting the insertion. Part 13 disengages from the insertion slot 12; the right elastic insertion plate 18 is the same as the left elastic insertion plate 14, and a right deformation space 19 is formed between the inner side of the right elastic insertion plate 18 and the insertion part 13. When the right elastic insertion plate 18 is located in the insertion slot 12, the right snap-fit ​​protrusion 21 on the outer side of the right elastic insertion plate 18 is located in the right snap-fit ​​hole 20 on the right inner wall of the insertion slot 12 and snaps into the cushion. At this time, the right elastic insertion plate 18 and the left elastic insertion plate 14 cooperate with each other, so that the connection between the guardrail fixing rod 10 and the cushion part 7 can be more stable and firm, thereby ensuring that the guardrail fixing rod 10 cannot be separated from the cushion part 7 without the action of external force.

[0045] Preferably, the surfaces of the right snap-fit ​​protrusion 21 and the left snap-fit ​​protrusion 17 are arc-shaped, making it easier for the user to install the guardrail fixing rod 10 onto or remove it from the seat cushion 7.

[0046] Preferably, the guardrail body 9 is provided with a first connecting member 22, which is rotatably sleeved on the guardrail body 9. The first connecting member 22 is provided with a fixing part 23, and the fixing part 23 is provided with a fixing groove 24. The top end of the guardrail fixing rod 10 is disposed in the fixing groove 24 and connected to the fixing part 23. The guardrail fixing rod 10 is connected to the guardrail body 9 through the first connecting member 22, and the top end of the guardrail fixing rod 10 is disposed in the fixing groove 24 of the fixing part 23. At this time, the guardrail fixing rod 10 and the first connecting member 22 are connected. The connection method of the connector 22 makes the connection between the guardrail fixing rod 10 and the first connector 22 more secure. Since the first connector 22 is rotatably sleeved on the guardrail body 9, when the guardrail body 9 is removed from the pull rod 2, the user can rotate the guardrail fixing rod 10 to drive the first connector 22 to rotate. Finally, the guardrail fixing rod 10 will enter the guardrail body 9, so that the guardrail fixing rod 10 and the guardrail body 9 are folded together, thereby reducing the storage space of the guardrail assembly 8 and making it convenient for the user to store.

[0047] Preferably, the connecting assembly 11 includes a second connecting member 25 and a trigger 27. The second connecting member 25 is connected to the guardrail body 9. The second connecting member 25 is provided with a connecting portion 26. The trigger 27 is hinged to one side of the connecting portion 26. After the trigger 27 is driven to rotate, the inner side of the trigger 27 will contact the other side of the connecting portion 26. At this time, an installation space 28 is formed between the trigger 27 and the connecting portion 26, and the pull rod 2 can be located within the installation space 28. On the other side of the connecting part 26, there is a latching protrusion 29, and on the inner side of the trigger 27, there is a latching groove 30. The latching protrusion 29 can be located in the latching groove 30 and engage with the trigger 27, thereby preventing the pull rod 2 from disengaging from the installation space 28. Since the trigger 27 is hinged to one side of the connecting part 26 of the second connecting member 25, and when the trigger 27 rotates relative to the connecting part 26, the inner side of the trigger 27 will contact the other side of the connecting part 26. At this time, a connection is formed between the trigger 27 and the connecting part 26. An installation space 28 is formed for the user to install the pull rod 2. On the other side of the connecting part 26, there is a latching protrusion 29, and on the inner side of the trigger 27, there is a latching groove 30. When the user drives the trigger 27 to rotate relative to the connecting part 26, the latching protrusion 29 will overlap with the latching groove 30, causing the latching protrusion 29 to engage with the trigger 27. This prevents the latching protrusion 29 from automatically disengaging from the latching groove 30, thus restricting the pull rod 2 from leaving the installation space 28, allowing the guardrail body 9 to... The guardrail body 9 can be smoothly installed onto the pull rod 2 via the connecting component 11. When the user wants to remove the guardrail body 9 from the pull rod 2, the user can forcefully turn the trigger 27 to separate the buckle groove 30 from the buckle protrusion 29. At this time, the installation space 28 formed between the trigger 27 and the connecting part 26 will open, thereby allowing the guardrail body 9 to be removed from the pull rod 2. This method of removing the guardrail body 9 is simple; the user only needs to turn the trigger 27 to complete the installation and removal of the guardrail body 9.

[0048] Preferably, the second connector 25 is rotatably mounted on the guardrail body 9. When the guardrail body 9 and the guardrail fixing rod 10 are disassembled, the user can rotate the second connector 25 so that the second connector 25, the connecting part 26 and the trigger 27 enter the guardrail body 9, so that the second connector 25 and the guardrail body 9 are folded together, thereby reducing the storage space of the guardrail assembly 8 and making it convenient for the user to store.

[0049] Preferably, the seat cushion 7 is provided with a soft pad 31, and the pull rod 2 is fitted with a handle 32. The handle 32 is located above the guardrail body 9, and the handle 32 is provided with a hook 33. The soft pad 31 makes it more comfortable for children to sit on the seat cushion 7, and the handle 32 on the pull rod 2 is located above the guardrail body 9. When a child sits on the seat cushion 7, the child can cover the handle 32 with their hand, so that the child's body is less likely to sway significantly when sitting on the cushion, thus preventing the child from accidentally falling off the seat cushion 7 to the ground. The hook 33 on the handle 32 allows the user to hang some items on the hook 33 without having to carry them themselves.

[0050] Preferably, the frame 34 is provided with a housing 1, which is located below and connected to the seat cushion 7. The frame 34 includes a frame body 4 and an auxiliary frame 5 inclinedly arranged on the frame body 4. The frame body 4 and the auxiliary frame 5 are in an "A" shape. The rolling wheels 3 are located at the bottom of the frame body 4, and the bottom of the auxiliary frame 5 is provided with auxiliary wheels 6. When using the frame 34 for outdoor play, the housing 1 can be used to store clothes, so that the stroller can not only be used as a stroller, but also as a pull handle. The stroller is designed for use in a box, and the frame 34 includes a main frame 4 and an auxiliary frame 5 that is tilted on the main frame 4. The main frame 4 and the auxiliary frame 5 are arranged in an "A" shape, which improves the overall load-bearing capacity of the frame 34. When the main frame 4 is tilted, the auxiliary wheel 6 at the bottom of the auxiliary frame 5 will contact the ground, so that part of the weight of the box 1 can be distributed to the auxiliary frame 5, thereby reducing the weight borne by the user's arm. When the user pulls the box 1, the auxiliary wheel 6 can rotate together with the rolling wheel 3, making it easier for the user to pull the stroller.
