Description

Technical Field

[0001] The present invention relates to the field of baby carriages, and in particular to a multifunctional baby carriage. Background Art

[0002] Generally speaking, when taking preschool children (including infants and toddlers) for a walk or going out, the most basic thing they need may be a stroller. The stroller generally adopts the following basic structure: wheels are connected to the lower part, the seat is connected to the central part of the frame, the handle is located at the upper part, and the storage basket can easily store light and small items. For example, children's products can be placed in the storage basket located at the lower part of the frame under the seat.

[0003] According to the above structure, baby strollers are divided into fixed-frame baby strollers and foldable-frame baby strollers. Baby strollers with fixed frames are limited in use because they can only be used as baby strollers, so they have the disadvantage of reduced practicality. Foldable-frame baby strollers need to consider whether the folding structure is complicated and whether the support is stable. At the same time, as the use cycle of baby strollers shortens, baby strollers will not be abandoned due to failures, etc., while in most cases, baby strollers are abandoned when they exceed the age required for use by babies. Therefore, such abandoned or unused baby strollers have the problem of causing serious waste of resources and environmental pollution. On this basis, reference can be made to an outdoor multifunctional camping cart recorded in the Chinese utility model patent with announcement number "CN219339487U", in which the body adopts a foldable design. Since the body can be folded simply and quickly, it does not require too much operation, which is conducive to storage, and can be loaded through the storage basket under the seat of the body, which is convenient for users to assist in carrying items when driving to the vicinity of the destination. However, baby strollers have obvious differences in use requirements and structures from other vehicles for carrying items (such as camping cars), and are not suitable for assisting in carrying items.

[0004] In view of the existence of the above-mentioned technical problems, the present invention aims to expand the use functions of the baby stroller and proposes a new folding structure on this basis. Summary of the invention

[0005] In order to solve the above problems, the purpose of the present invention is to provide a multifunctional baby stroller. This solution realizes the lifting and lowering of the cabin body and the upper frame based on the support assembly, so that it can switch between at least two states of a baby stroller and a camper, adapting to a variety of different usage scenarios.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: A multifunctional baby stroller comprises a lower frame with wheels mounted on the lower end, an upper frame connected to the lower frame via a support assembly, and a cabin body mounted on the upper frame; the lower frame is provided with a storage basket below the cabin body; the upper frame and the cabin body thereon are lifted and lowered on the lower frame via a support assembly; when the cabin body sinks into the storage basket based on the support assembly, the cabin body and the storage basket enclose a storage cavity.

[0007] The present invention adopts the above-mentioned technical solution, which relates to a multifunctional baby stroller, in which wheels are installed under the lower frame, including front wheels and rear wheels; the upper frame is connected to the lower frame through a supporting assembly, and a cabin body is installed in the upper frame for infants to sit in, and a storage basket under the cabin body can provide a certain storage space when in the stroller state.

[0008] On this basis, the present solution is different from the prior art in that the support assembly in the present solution is a lifting support assembly, through which the upper frame and the cabin body thereon can be lifted and lowered relative to the lower frame; when descending to the lowest position, the cabin body sinks into the storage basket and is enclosed with the storage basket to form a storage cavity; in this state, it can be used as a camper, expanding the storage space.

[0009] Based on the above scheme, this scheme realizes the lifting and lowering of the cabin body and the upper frame based on the support assembly, so that it can switch between at least two states of a baby stroller and a camper, adapting to a variety of different usage scenarios. And it retains the characteristics of a high-view baby stroller and the storage space of a camper.

[0010] In a specific embodiment, the storage basket includes a bottom frame, and a bottom bib disposed above the bottom frame; the spacing between the two side cloths of the bottom bib is greater than or equal to the maximum width formed by the cabin body or the upper frames on both sides thereof, and at least the two side edges of the rear cloth of the bottom bib are detachably connected to the rear side of the side cloth or the lower frame. In this scheme, the technical scheme requires that the shape and structure of the storage basket will not interfere with the lifting and lowering of the cabin body, thereby allowing the cabin body to sink into the storage basket. Therefore, the spacing between the two side cloths of the bottom bib in this scheme is greater than or equal to the maximum width formed by the cabin body or the upper frames on both sides thereof, that is, the two side cloths of the bottom bib are at least not smaller than the maximum width formed by the upper frame, so that the widths on the left and right sides of the bottom bib allow the cabin body to sink.

[0011] Furthermore, it is necessary to allow the rear cloth of the bottom bib to be removed or lowered, so that when the cabin body sinks into the storage basket, the rear end thereof extends out of the storage basket without being interfered by the rear cloth, thereby expanding the storage space when the camper is in use.

[0012] In a further solution, in order to ensure the support strength of the storage space used as a camper, the bottom frame of the storage basket is constructed as a hard bottom frame connected to the lower frame and having support strength. When in use, the lower end of the cabin body is supported by the hard bottom frame, thereby providing a relatively stable, non-deformable and support-strength storage space.

[0013] Preferably, the cabin body or the upper frame around it can be connected to the bottom frame of the storage basket or the lower frame around it through a buckle assembly, so that the cabin body is fixed in the storage basket. In this solution, the sunken cabin body is clamped with the bottom frame or the lower frame through the buckle assembly, so that the two are relatively fixed. At this time, the whole vehicle is fixed in the state of a camper, and the cabin body and the upper frame will not rise and fall when the vehicle is pushed or pulled.

[0014] In a specific implementation, the buckle assembly includes a hook disposed on a rear crossbar at the rear side of the storage basket, and a clamping block disposed on the cabin body or the upper frame at the rear side thereof; the rear crossbar is also provided with a pedal for driving the hook. The scheme here is based on the clamping of the hook and the clamping block, so that the cabin body is fixed in the storage basket. When the vehicle needs to be adjusted to the state of a baby carriage, it is only necessary to act on the pedal (such as stepping on it) to drive the hook and the clamping block to unlock, thereby allowing the upper frame and the cabin body to be lifted upward.

[0015] The supporting assembly of the above solution may be a lifting structure such as a scissor bracket.

[0016] However, in the preferred embodiment, the support assembly includes at least one group of front support rods and a rear support rod for supporting the front support rods in the raised state, the lower end of the front support rod is hinged to the front end of the lower frame, the upper end of the front support rod is hinged to the upper frame on the side of the cabin body and is controlled by the seat locking assembly; the cabin body and the upper frame are swung and lifted relative to the lower frame based on the front support rods. In this embodiment, the two ends of a group of front support rods in the support assembly are respectively rotatably connected to the upper frame on the side of the cabin body and the front end of the lower frame; during the folding and lifting process, the front support rods can be used as swing rods to lift and lower in a swinging manner. In this embodiment, the seat locking assembly is used to control the locking or release of the hinge between the upper end of the front support rod and the upper frame. The purpose is that during the adjustment process, the position is required to be relatively rotated so that the lower end surface of the cabin body is placed in the storage basket in a substantially horizontal manner. In the state of a baby carriage, the front support rod is required to provide stable support for the cabin body and the upper frame, so it is necessary to lock it through the seat locking assembly.

[0017] This lifting structure is relatively simple and stable, and the adjustment is relatively convenient.

[0018] When the baby carriage is positioned in a baby carriage state, the front support rod is supported by the rear support rod. Specifically, the following scheme is adopted: the lower end of the rear support rod is fixedly connected / rotatably connected / detachably connected to the rear end of the lower bracket; when the rear support rod supports the front support rod in the raised state, the rear support rod is fixed relative to the lower bracket. In this scheme, the rear support rod can be fixed, rotatable or detachable, and only needs to be fixed to the lower bracket in the supporting state.

[0019] In a specific implementation scheme, the front support rods on both sides are connected by a locking link. In the scheme shown in the figure, the front support rod locking links are connected by a connecting piece. An adjustment locking assembly is built into the locking link, which includes a lock tongue that can move forward and backward from both ends of the locking link, and an operating component that drives the lock tongue to move forward and backward; the operating component adopts an unlocking handle in an implementable embodiment, and the unlocking handle can be rotated when in use. For example, two sets of screw rod structures can be used to drive the lock tongues on both sides to move forward and backward, and a locking seat for the lock tongue to extend and lock is provided on the upper end of the rear support rod. The lock tongue is inserted into the locking seat to fix the front support rod on the rear support rod to achieve support.

[0020] In a further embodiment, a push rod is further included; the lower end of the push rod is hingedly arranged on the upper end of the rear support rod. The push rod must be equipped on the baby carriage. The push rod in this embodiment can rotate with its lower end as the axis, so that it can be adjusted forward and backward, and is used to switch between pushing the vehicle and pulling the vehicle.

[0021] Preferably, the cabin body includes a seat and a footrest hinged on the front end of the seat, and the footrest can rotate relative to the seat; when the cabin body is sunk into the storage basket based on the support assembly, the footrest can rotate to be substantially flush with the seat surface of the seat and its bottom is mounted on the bottom frame of the storage basket. In this solution, the footrest is a common component of a baby stroller, and this solution requires that the footrest can rotate relative to the seat and at least be able to rotate to be substantially flush with the seat surface of the seat, so that it is laid on the bottom frame of the storage basket when it sinks into the storage basket.

[0022] Preferably, the seat and backrest of the chair are rotatably connected, and a folding canopy is also connected to the upper frame on the back side of the seat, and the backrest and the folding canopy thereon can be rotated along their axis points to cover the seat. In the scheme here, the backrest and the folding canopy thereon can be folded and stored relative to the seat, so that the camping car state can be further folded into the storage state, reducing the storage space occupied by the storage.

[0023] Preferably, the rear wheels connected to the two ends of the rear crossbar of the lower frame are equipped with hub motors, and the rear crossbar is equipped with a battery assembly for supplying power to the hub motors; the push rod is provided with a controller connected to the hub motor signal. In this scheme, the baby carriage is equipped with an electric power-assisted pushing function, and the forward speed of the hub motor is controlled by a remote control. The two rear wheels are equipped with hub motors respectively, and the left and right directions can be coordinated by the difference between the two wheels.

[0024] In a further solution, the controller is connected to the wheel hub motor based on a wireless signal, and the controller can be detachably connected to the push rod. The remote control is adsorbed on the push rod handle by magnetic attraction, and can be used directly on the handle or removed for use. This product provides a total of 3 speeds to choose from (3, 5, and 6 km / h, matching the walking speeds of the elderly, adult women, and adult men respectively). When the vehicle is fully loaded (80kg) and is electrically driven, it can travel 5 kilometers at a speed of 5 km / h. The parameters of the wheel hub motor are six inches, 350w, and 36v. The battery parameters are 36v and 8Ah. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more, unless otherwise clearly specified.

[0035] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0037] like Figures 1 to 7As shown, this embodiment relates to a multifunctional baby stroller, comprising a lower frame 1 with wheels installed at the lower end, an upper frame 2 connected to the lower frame 1 through a support assembly 5, and a cabin body 3 installed on the upper frame 2; the lower frame 1 is provided with a storage basket 4 below the cabin body 3. Wheels are installed below the lower frame 1 in the multifunctional baby stroller, including a front wheel 101 and a rear wheel 102. The upper frame 2 is connected to the lower frame 1 through a support assembly 5, and a cabin body 3 is installed in the upper frame 2 for infants to sit on. The storage basket 4 below the cabin body 3 can provide a certain storage space in the baby stroller state.

[0038] On this basis, the present solution is different from the prior art in that the upper frame 2 and the cabin body 3 thereon are lifted and lowered on the lower frame 1 by means of a support assembly 5. When the cabin body 3 sinks into the storage basket 4 based on the support assembly 5, the cabin body 3 and the storage basket 4 enclose a storage cavity. The support assembly 5 in the present solution is a lifting support assembly 5, through which the upper frame 2 and the cabin body 3 thereon can be lifted and lowered relative to the lower frame 1. When descending to the lowest position, the cabin body 3 sinks into the storage basket 4 and encloses the storage basket 4 to form a storage cavity. In this state, it can be used as a camper, which expands the storage space.

[0039] Based on the above scheme, this scheme realizes the lifting and lowering of the cabin body 3 and the upper frame 2 based on the support assembly 5, so that it can switch between at least two states of a baby stroller and a camper, adapting to a variety of different usage scenarios. And it retains the characteristics of a high-view baby stroller and the storage space of a camper.

[0040] like Figures 1 to 3 In the specific embodiment shown in , the storage basket 4 includes a bottom frame 41, and a bottom bib arranged above the bottom frame 41. The spacing between the two side cloths 421 of the bottom bib is greater than or equal to the maximum width formed by the cabin body 3 or the upper frames 2 on both sides thereof, and at least the two side edges of the rear cloth 422 of the bottom bib are detachably connected to the rear side of the side cloth 421 or the lower frame. In this scheme, the technical scheme requires that the shape and structure of the storage basket 4 will not interfere with the lifting and lowering of the cabin body 3, thereby allowing the cabin body 3 to sink into the storage basket 4. Therefore, the spacing between the two side cloths 421 of the bottom bib in this scheme is greater than or equal to the maximum width formed by the cabin body 3 or the upper frames 2 on both sides thereof, that is, the two side cloths 421 of the bottom bib are at least not smaller than the maximum width formed by the upper frame, so that the width of the left and right sides of the bottom bib allows the cabin body 3 to sink.

[0041] Furthermore, it is necessary to allow the rear cloth 422 of the bottom bib to be removed or put down, so that when the cabin body 3 sinks into the storage basket 4, the rear end extends out of the storage basket 4 and is not interfered by the rear cloth 422, thereby expanding the storage space when the camper is in use. At least the two side edges of the rear cloth 422 here can be detachably connected to the rear side of the side cloth 421 or the lower frame, such as by a zipper as shown in the figure, or by Velcro adhesion, snap fastening, etc. In a further scheme, in order to ensure the support strength of the storage space used as a camper. In this scheme, the bottom frame 41 of the storage basket 4 is constructed as a hard bottom frame 41 connected to the lower frame and having support strength. When in use, the lower end of the cabin body 3 is supported by the hard bottom frame 41, thereby providing a relatively stable, non-deformable and support-strength storage space.

[0042] like Figure 2 and 3 As shown, the cabin body 3 or the upper frame 2 around it can be connected with the bottom frame 41 of the storage basket 4 or the lower frame 1 around it through a buckle assembly. So that the cabin body 3 is fixed in the storage basket 4. In this scheme, the sunken cabin body 3 is clamped with the bottom frame 41 or the lower frame 1 by the buckle assembly, so that the two are relatively fixed. At this time, the whole vehicle is fixed in the camping car state, and when the vehicle is pushed or pulled, the cabin body 3 and the upper frame 2 will not fluctuate. In a specific implementation scheme, the buckle assembly includes a hook 61 arranged on the rear cross bar 11 on the rear side of the storage basket 4, and a clamping block 62 arranged on the cabin body 3 or the upper frame 2 on the rear side. The rear cross bar 11 is also provided with a pedal 63 for driving the hook 61. The scheme here is based on the clamping of the hook 61 and the clamping block 62, so that the cabin body 3 is fixed in the storage basket 4. When the vehicle needs to be adjusted to the baby carriage state, it is only necessary to act on the pedal 63 [such as stepping on it], thereby driving the hook 61 and the clamping block 62 to unlock, thereby allowing the upper frame 2 and the cabin body 3 to be lifted upward.

[0043] The support assembly 5 of the above solution can be a lifting structure such as a scissor bracket.

[0044] But in Figures 1 to 4In the preferred embodiment shown, the support assembly 5 includes at least one group of front support rods 51 and a rear support rod 52 for supporting the front support rods 51 in a raised state. The lower end of the front support rod 51 is hinged to the front end of the lower frame 1, and the upper end of the front support rod 51 is hinged to the upper frame 2 on the side of the cabin body 3 and controlled by the seat locking assembly 53. The cabin body 3 and the upper frame 2 are swung and lifted relative to the lower frame 1 based on the front support rods 51. In this embodiment, the two ends of a group of front support rods 51 in the support assembly 5 are rotatably connected to the upper frame 2 on the side of the cabin body 3 and the front end of the lower frame 1, respectively. During the folding and lifting process, the front support rod 51 can be used as a rocker to lift and lower in a swinging manner. In this scheme, the seat locking assembly 53 is used to control the locking or releasing of the hinge between the upper end of the front support rod 51 and the upper frame 2. The purpose is that during the adjustment process, the position is required to be relatively rotated so that the cabin body 3 is placed in the storage basket 4 in a substantially horizontal manner at the lower end surface. In the baby carriage state, the front support rod 51 is required to provide stable support for the cabin body 3 and the upper frame 2, so it needs to be locked by the seat locking assembly 53. This lifting structure is relatively simple and stable, and the adjustment is relatively convenient.

[0045] When the baby carriage is positioned in a baby carriage state, the front support rod 51 is supported by the rear support rod 52. Specifically, the following scheme is adopted: the lower end of the rear support rod 52 is fixedly connected / rotatably connected / detachably connected to the rear end of the lower bracket. When the rear support rod 52 supports the front support rod 51 in the raised state, the rear support rod 52 is fixed relative to the lower bracket. In this scheme, the rear support rod 52 can be fixed, rotatable or detachable, and only needs to be fixed to the lower bracket in the supporting state.

[0046] exist Figure 2 and 4 In the specific implementation scheme shown, the front support rods 51 on both sides are connected by a locking link 54, and in the scheme shown in the figure, the front support rod 51 and the locking link 54 are connected by a connecting piece 55. An adjustment locking assembly is built into the locking link 54, and the adjustment locking assembly includes a lock tongue 561 that can move forward and backward from both ends of the locking link 54, and an operating component that drives the lock tongue 561 to move forward and backward. The operating component adopts an unlocking handle 562 in the implementation scheme, and the unlocking handle 562 can be rotated when in use. For example, two sets of screw rod structures can be used to drive the lock tongues 561 on both sides to move forward and backward, and a locking seat 521 for the lock tongue 561 to extend and lock is provided on the upper end of the rear support rod 52. The lock tongue 561 is inserted into the locking seat 521 to fix the front support rod 51 on the rear support rod 52 to achieve support.

[0047] like Figure 1 and 5As shown, the push rod 7 is also included. The lower end of the push rod 7 is hingedly arranged on the upper end of the rear support rod 52. The push rod 7 must be equipped on the baby carriage. The push rod 7 in this solution can rotate with its lower end as the axis, so that it can be adjusted forward and backward, and is used to switch between pushing the vehicle and pulling the vehicle.

[0048] like Figure 1 and 5 As shown, the cabin body 3 includes a seat 31 and a footrest 32 hinged on the front end of the seat 31, and the footrest 32 can rotate relative to the seat 31. When the cabin body 3 sinks into the storage basket 4 based on the support assembly 5, the footrest 32 can rotate to be substantially flush with the seat surface of the seat 31 and its bottom is mounted on the bottom frame 41 of the storage basket 4. In this scheme, the footrest 32 is a common component of a baby stroller. This scheme requires that the footrest 32 can rotate relative to the seat 31 and at least be able to rotate to be substantially flush with the seat surface of the seat 31, so that it is laid on the bottom frame 41 of the storage basket 4 when it sinks into the storage basket 4. The seat and backrest of the seat 31 are rotatably connected, and a folding canopy 33 is also connected to the upper frame 2 on the back side of the seat. The backrest and the folding canopy 33 thereon can rotate along their axis points to cover the seat. In the solution here, the chair back and the folding canopy 33 thereon can be folded and stored relative to the chair seat, so that the camping vehicle state can be further folded into the storage state, reducing the storage space occupied by the storage.

[0049] Finally, the rear wheels 102 connected at both ends of the rear crossbar 11 of the lower frame 1 are built with hub motors, and the rear crossbar 11 is built with a battery assembly for supplying power to the hub motor. A controller 8 connected to the hub motor signal is provided on the push rod 7. In the scheme here, the function of electric power propulsion is added to the baby carriage, and the forward speed of the hub motor is controlled by a remote control. The two rear wheels 102 are respectively built with hub motors, and the left and right directions can be coordinated by the difference between the two wheels. The controller 8 is connected to the hub motor based on a wireless signal, and the controller 8 is detachably connected to the push rod 7. The remote control is adsorbed on the handle of the push rod 7 by magnetic attraction, and can be used directly on the handle or removed for use. This product provides a total of 3 speeds for selection, 3, 5, and 6 km / h, which match the walking speeds of the elderly, adult women, and adult men respectively. When the car is fully loaded with 80 kg and is electrically driven, it can travel 5 kilometers at a speed of 5 km / h. The parameters of the hub motor are six inches, 350w, and 36v. The battery parameters are 36v, 8Ah.

[0050] In summary, the multifunctional baby stroller involved in the technical solution proposes a new folding structure, which can be converted into a stroller, a camper and a folded state; so that the stroller can adapt to a variety of different usage scenarios. In actual implementation, the height of the seat 31 in the stroller form is 60cm, retaining the characteristics of a high-view stroller. In the camper form, it has a 35L storage space and the height of the surrounding fence is 15cm. In the fully folded state, it is 70cm long, 65cm wide and 30cm high.
