Description

Technical Field

[0001] The utility model relates to the technical field of baby carriages, and more specifically to a split-type baby carriage which can be folded and unfolded quickly. Background Art

[0002] Modern parents often need to carry a stroller and luggage when traveling. Carrying separate strollers and luggage will take up more space, which is particularly inconvenient in environments with limited space such as public transportation, airports, train stations or elevators. It may be a physical challenge for parents, especially when they need to walk for a long time or go up and down stairs. In busy public places, carrying multiple items may also cause parents to be distracted, increase the risk of children getting lost or other safety issues. If a product can be designed that can be used as a stroller and can be easily converted into a suitcase, it will greatly reduce the burden on users when traveling, thereby improving the travel experience. Therefore, luggage strollers that emphasize versatility and practicality came into being and are favored by parents.

[0003] In order to further reduce the occupied space and facilitate carrying and storage, some luggage strollers are designed to be foldable, such as the luggage stroller disclosed in the Chinese patent with publication number CN215794262U and patent name "A scooter and scooter luggage". The luggage stroller is a folding structure, but the luggage cannot be disassembled, so that the luggage and the stroller cannot be used independently in some occasions where they need to be used separately, and the folding structure is quite complicated and inconvenient to produce and use.

[0004] The Chinese patent with publication number CN212074314U and patent name "A detachable and foldable skateboard luggage cart" discloses a luggage stroller in which not only the luggage and the stroller parts can be separated from each other, so that the user can use it in a variety of occasions, but also has a folding function. However, the luggage stroller still has the following problems, namely, the connection stability between the luggage and the stroller is poor. Specifically, the luggage and the stroller are connected through two sets of direct plug-in cooperation between the front hanging groove of the hanger body and the hanger nut slot, and between the docking nut and the docking groove of the lower hanger. Therefore, when the luggage is subjected to an upward external force consistent with the axial direction of the upper support rod of the scooter, the luggage is very easy to fall off, which may not only cause injuries to children, but also damage the stored items, and easily cause damage to its own components, shortening the service life, and seriously affecting the user's experience.

They are only for the convenience of simplifying the description, and do not indicate or imply that the directions are specific directions that must be possessed and specific directions, structures, and operations, and therefore should not be understood as limitations on the present utility model.

[0040] like Figures 1 to 3 As shown, the utility model relates to a split-type luggage baby stroller that can be quickly folded and unfolded, which includes a vehicle body 1 and a luggage body 2. The vehicle body 1 includes a front frame 1a and a rear frame 1b. The front frame 1a and the rear frame 1b are cross-hinged. The vehicle body 1 can be switched between a folded state and an unfolded state by controlling the front frame 1a and the rear frame 1b to rotate relative to or away from each other. The folded state is convenient for storage to save storage space as much as possible. A rotation-stopping assembly 1c is slidably connected between the hinged positions of the front frame 1a and the rear frame 1b. The front frame 1a and the rear frame 1b are hinged. The first rotating shaft and the second rotating shaft on the joint are the first constraints, and the second constraint is formed when the anti-rotation component 1c cooperates with the rear frame 1b, thereby limiting the relative rotation of the front frame 1a and the rear frame 1b to fix and maintain the folded or unfolded state. By moving the anti-rotation component 1c to disengage from the matching position with the rear frame 1b, the fixation of the current state of the vehicle body 1 can be released so that the folded and unfolded states can be switched normally. The front frame 1a has a box installation position a17 for placing luggage, and the luggage body 2 is arranged on the box installation position a17, and is specifically embedded and installed in the box installation position a 17, so that installation and removal can be completed by plugging and unplugging, the upper and lower sides of the box installation position a17 are slidably connected with the upper stop component 1d and the lower stop component 1e, and the upper stop component 1d and the lower stop component 1e are also slidably matched with the luggage body 2. In the matched state, the upper and lower sides of the luggage body 2 are respectively constrained to form a stable fixation with the vehicle body 1, thereby effectively resisting dislocation caused by accidental force, improving the safety of use, and the upper stop component 1d and the lower stop component 1e can be detached from the matching position with the luggage body 2 by sliding. After the upper and lower constraints are released, the luggage body 2 The body 2 can be removed from the matching position of the box body, so that the vehicle body 1 and itself can be used separately, which can better meet the user's usage needs in different occasions. In addition, the anti-rotation component 1c, the upper stop component 1d and the lower stop component 1e are all matched with the front frame 1a and the rear frame 1b, as well as the front frame 1a and the luggage body 2 in a sliding manner, without the need for complex gears, cams or other motion conversion mechanisms. Therefore, the structure is simple, which is convenient for the user to quickly fold or unfold the vehicle body 1 when applying control, and convenient for the disassembly and assembly of the luggage body 2. At the same time, it is easy to design and manufacture.

[0041] like Figures 3 to 6 As shown, the anti-rotation assembly 1c includes an anti-rotation wheel c11 and an anti-rotation spring c12, and the opposite surfaces of the front frame 1a and the rear frame 1b are respectively provided with an inner slideway a111 and an outer slideway b111, the inner slideway a111 and the outer slideway b111 are opposite and connected, and are combined to form a complete slideway, the anti-rotation wheel c11 is slidably matched with the inner slideway a111 and the outer slideway b111, and the shapes of the matching surfaces are non-circular to limit the relative rotation between the anti-rotation wheel c11 and the front frame 1a and the rear frame 1b, and the depth of the inner slideway a111 exceeds the height of the anti-rotation wheel c11, ensuring that the anti-rotation wheel c11 By sliding, the vehicle can completely enter the inner slide a111 to disengage from the rear frame 1b, thereby realizing the relative rotation of the front frame 1a and the rear frame 1b. The anti-rotation spring c12 is arranged in the inner slide a111, and connects the inner wall of the inner slide a111 and the anti-rotation wheel c11. In the initial state, the anti-rotation wheel c11 is supported by the anti-rotation spring c12 and is located in the outer slide b111 and the inner slide a111 at the same time. The anti-rotation spring c12 is compressed to generate elastic potential energy when the anti-rotation wheel c11 moves toward the inner slide a111, so as to prepare for the anti-rotation wheel c11 to be reset and to be matched with the rear frame 1b again.

[0042] like Figures 3 to 6 As shown, the anti-rotation assembly 1c also includes a rotation control component c13. A anti-rotation pressure groove b112 is opened on the side wall of the rear frame 1b away from the front frame 1a. The anti-rotation pressure groove b112 is opposite to the outer slide b111 and is connected to the outer slide b111 through the through groove b113. The rotation control component c13 slides in cooperation with the anti-rotation pressure groove b112. A pawl c131 is formed on the rotation control component c13. The pawl c131 passes through the through groove b113 and abuts against the anti-rotation wheel c11. The rotation control component c13 is exposed to the external space for the user to apply pressure control. The rotation control component c13 transmits pressure to the anti-rotation wheel c11, thereby providing power for the anti-rotation wheel c11 to slide along the inner slide a111 and the outer slide. When the applied force is removed, under the elastic force of the anti-rotation spring c12, the rotation control component c13 can be reset synchronously with the anti-rotation wheel c11.

In the plugged state, the upper part of the luggage body 2 is positioned by the upper plug block d12. The upper plug block d12 is provided with a guide groove d121 opposite to the push block d11, and the guide groove d121 is parallel to the upper stop channel a113. The push block d11 is embedded in the guide groove d121 and cooperates with the top wall slope of the guide groove d121. When the push block d11 is pushed to the upper operating channel a1 When the upper insert block d12 moves in the upper stop channel a113, it can drive the upper insert block d12 to move inside the upper stop channel a113, so that it can be disengaged from the slot 201 on the luggage body 2 to unlock. The upper stop spring d13 is arranged in the upper stop channel a113 and connects the inner wall of the upper stop channel a113 and the upper insert block d12. Similar to the anti-rotation spring c12, the upper stop spring d13 is compressed to generate elastic potential energy when the upper insert block d12 moves in the upper stop channel a113, so as to prepare for the upper insert block d12 to reset and re-match with the luggage body 2. The side wall of the upper insert block d12 close to the installation direction of the luggage body 2 is an inclined surface, which ensures that when the luggage body 2 is installed back to the case installation position a17, the luggage body 2 can apply pressure on this inclined surface, thereby pushing the upper insert block d12 to automatically move inward along the upper stop channel a113. When the luggage body 2 is installed in place, the upper slot 201 is opposite to the upper stop channel a113, and under the action of the upper brake spring force, the upper insert block d12 is automatically embedded in the upper slot 201. The entire process does not require the user to manually control the movement, thereby improving the installation efficiency of the luggage body 2.

[0044] like Figures 10 to 13 as well as Fig.16As shown, the lower stop assembly 1e includes a lower insert block e11 and a lower stop spring e12, a lower operating channel a121 and a lower stop channel a122 are provided on the front frame 1a, the lower operating channel a121 is located on the lateral side of the lower stop channel a122, and penetrates the side wall of the front frame 1a, the luggage body 2 is opposite to the lower stop channel a122 up and down, and one end of the lower stop channel a122 close to the luggage body 2 penetrates the side wall of the front frame 1a, the lower insert block e11 is slidably matched with the lower stop channel a122, and a shift block e111 is formed on the lower insert block e11, the shift block e111 is slidably matched with the lower operating channel a121, and the shift block e111 also extends outside the lower operating channel a121 for user control, and the lower insert block e11 is controlled to move along the lower stop channel a122 by shifting the shift block e111. 2 moves up and down, a lower slot 202 is provided on the bag body 2 for plugging with the lower plug block e11, and the lower part of the bag body 2 is positioned by the lower plug block e11 in the plugged state, and the upper plug block d12 of the upper stop assembly 1d is cooperated to realize the stable fixation of the bag body 2 and the vehicle body 1, and when the lower plug block e11 moves into the lower stop channel a122, it is disengaged from the lower slot 202, and the bag body 2 can be unlocked, and the lower stop spring e12 is arranged in the lower stop channel a122, and connects the inner wall of the lower stop channel a122 and the lower plug block e11, and the function of the lower stop spring c12 and the upper stop spring d13 is similar in that the lower stop spring e12 is compressed to generate elastic potential energy when the lower plug block e11 moves into the lower stop channel a122, so as to prepare for the lower plug block e11 to be reset to re-match with the bag body 2.

[0045] like Figures 10 to 13As shown, the lower stop assembly 1e also includes a lock tongue e13 and a limit spring e14. A lock groove e112 is provided on the side wall of the lower plug block e11 close to the lower operating channel a121. The lock tongue e13 slidably cooperates with the lock groove e112. The limit spring e14 is arranged in the lock groove e112 and connects the inner wall of the lock groove e112 and the lock tongue e13. When the lower plug block e11 slides, the lock tongue e13 moves synchronously between the relative position and the separation relative position with the lower operating channel a121. When it is not relative to the lower operating channel a121, it is squeezed by the inner wall of the lower stop channel a122 and is completely located in the lock groove e112. At this time, the limit spring e14 is in a compressed state. When the lower plug block e11 slides to be relative to the lower operating channel a121, the lock tongue e13 is driven by the limit spring e14 to be inserted into the lower operating channel a121 and is released by the limit spring The axial support of the spring e14 is stably maintained in the lower operating channel a121. At this time, the lower stop spring e12 is in a compressed state, and under the action of its elastic force, the lock tongue e13 is pushed to resist the top wall of the lower operating channel a121, thereby effectively overcoming the further recovery of the lower stop spring e12 and preventing the lower plug block e11 from sliding out of the lower stop channel a122. The side wall opposite to the top wall of the lower operating channel a121 is an inclined surface. When the user pushes the push block e111 upward to reset the lower plug block e11, the inner wall of the lock groove e112 pushes the lock tongue e13 upward to make it move upward, and the pressure between it and the top wall of the lower operating channel a121 increases. Guided by the inclined surface, it can finally move back to the lock groove e112 under the action of pressure, thereby releasing the restriction on the movement of the lower plug block e11 and ensuring that the lower plug block e11 can be reset normally.

The outer wall of the pedal b15 is formed with The locking convex b151 can rotate with the pedal b15 to be opposite to the adjusting piece b16, and squeeze the adjusting piece b16 to make it fit with the wheel frame b12. When the sleeve b14 drives the pedal b15 to move to a suitable position of the wheel frame b12, a large friction force is generated between the adjusting piece b16 and the wheel frame b12, so that the sleeve b14 and the pedal b15 are kept in any adjusted position, realizing stepless adjustment to better match the foot placement needs of children of different heights when riding.

[0049] like Figure 3 As shown, the front frame 1a also includes a cup holder a15 and a mobile phone holder a16, both of which are arranged on the pull rod a13, wherein the back frame a15 is used to place a water cup, and the mobile phone holder a16 is used to hold a mobile phone, so as to provide users with additional storage functions.

[0050] Combination Figures 1 to 16The folding and unfolding of the vehicle body 1 and the disassembly and assembly of the luggage body 2 of the luggage baby stroller of the utility model are characterized by being fast and convenient. When the front frame 1a and the rear frame 1b of the vehicle body 1 are to be unfolded or folded, it is only necessary to press the rotation control member c13 of the anti-rotation assembly 1c, and the rotation control member c13 transmits the pressure to the anti-rotation wheel c11, driving the anti-rotation wheel c11 to move toward the inner slideway a111 of the seat a11, and the anti-rotation spring c12 is compressed until it is completely separated from the outer slideway b111 of the rotating seat b11, and the front frame 1a and the rear frame 1b can be rotated normally to be folded or unfolded. When the pressure applied to the rotation control member c13 is removed, the anti-rotation spring c 12 drives the stop wheel c11 to reset and re-embed the outer slide b111 to dock with the swivel seat b11, so that the vehicle body 1 can maintain the adjusted state. When the luggage body 2 is to be disassembled, the push block d11 of the upper stop assembly 1d is pressed, and the push block d11 drives the upper plug block d12 to move into the upper stop channel a113 to disengage it from the docking with the slot 201 on the luggage body 2, unlocking the upper part of the luggage body 2, and at the same time, the push block e111 on the lower plug block e11 of the lower stop assembly 1e is pushed downward to drive the lower plug block e11 to move into the lower stop channel a122 until it disengages from the lower slot 202 of the luggage body 2, and the lower brake spring is compressed. Ensure that the lock slot e112 reaches the relative position with the lower operating channel a121, the lock tongue e13 is driven by the limit spring e14 to be inserted into the lower operating channel a121, and the lower insert block e11 is restricted from resetting. At this time, the upper stop assembly 1d and the lower stop assembly 1e are in restraining contact with the luggage body 2, and the user can smoothly disassemble the luggage body 2. When it is to be reassembled, the luggage body 2 is embedded in the box installation position a17. During the embedding process, the luggage body 2 applies pressure to the inclined surface of the upper insert block d12 opposite to its installation direction, thereby pushing the upper insert block d12 to automatically move inward along the upper stop channel a113. When the luggage body 2 is installed in place, the upper slot 201 is in contact with the upper stop Relative to channel a113, under the action of the elastic force of the upper brake spring, the upper insert block d12 automatically embeds into the upper slot 201 to position the upper part of the luggage body 2, and finally the dial block e111 is pulled back to drive the lower insert block e11 to reset, and the inner wall of the lock slot e112 pushes the lock tongue e13 upward to make it have an upward movement trend, and the pressure between it and the top wall of the lower operating channel a121 increases. Using the inclined guide, it can finally move back to the lock slot e112 under the action of pressure, thereby releasing the restriction on the movement of the lower insert block e11. At this time, the lower brake spring can be fully restored, thereby driving the lower insert block e11 to embed into the lower slot 202 of the luggage body 2, so that the luggage body 2 is firmly fixed on the vehicle body 1.

[0051] The above embodiments and descriptions are only for explaining the principle and the best embodiment of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements shall fall within the scope of the present invention to be protected.
