Description

[0001] This application claims the priority of a Chinese patent application filed with the State Intellectual Property Office on June 24, 2024, with application number 2024108218272 and application name “A type of multifunctional child seat for two-wheeled vehicles and its folding safety device”, all contents of which are incorporated by reference in this application. Technical Field

[0002] The invention relates to the field of child seats, in particular to a multifunctional child seat for a two-wheeled vehicle and a folding safety device thereof. Background Art

[0003] Bicycles and electric bicycles are common means of transportation for citizens to pick up and drop off their children to school because of their convenient parking. When kindergarten children under the age of six ride bicycles or electric bicycles, many cities require that fixed seats be installed on the back seat, and safety helmets should be worn when riding electric bicycles or bicycles. The "Electric Bicycle Safety Technical Specifications" (GB17761--2018) restricts the technical parameters of electric bicycles such as wheelbase and saddle length, and the carrying capacity of electric bicycles becomes very limited. After the rear safety seat is installed, the tail box cannot be installed, and the safety helmet loses an anti-theft storage space, which also limits the willingness to use high-quality safety helmets. The willingness to use the front basket of a bicycle is not high. On the one hand, the front basket affects the steering feel after loading, and on the other hand, the installation of the front basket is not very beautiful. After the fixed seat is installed on the rear cargo rack of the bicycle, there is also the problem of nowhere to store the helmet. Summary of the invention

[0004] In order to solve the problem that it is difficult to install a rear child seat for carrying people and a rear trunk for carrying goods on two-wheeled vehicles such as bicycles and electric bicycles, the present invention provides a two-wheeled vehicle multifunctional child seat and a folding safety device thereof. By folding part of the structure of the two-wheeled vehicle multifunctional child seat to form an enclosed space and using the folding safety device to lock the folding locking piece, the two-wheeled vehicle multifunctional child seat has the function of carrying goods, achieving a dual-purpose effect.

[0005] According to one aspect of the present invention, there is provided a first multifunctional child seat for a two-wheeled vehicle, comprising a folding mechanism, a base member, a limiting member, a front wall member, a backrest member and side wing members.

[0006] The folding mechanism includes a first folding member, a folding locking member and a second folding member. The folding locking member can be slidably arranged on the second folding member, or can be hinged to the second folding member, or can be detachably connected to the second folding member. A card slot is provided on the first folding member, and the card slot can cooperate with the folding locking member. In the state of carrying goods, the folding mechanism is limited in one direction, so that the multifunctional child seat of the two-wheeled vehicle cannot be transformed into the state of carrying people. It should be noted that: the folding locking member is designed to be tilted and slidably arranged on the second folding member, so that the self-locking of the folding mechanism can be achieved; the folding locking member is designed to be hinged to the second folding member, and the center of gravity of the folding locking member can be used to achieve the self-locking of the folding mechanism; the folding locking member with a thread is designed to be detachably connected to the second folding mechanism, so that the self-locking of the folding mechanism can also be achieved. Another aspect of the present invention also provides a folding safety device for a multifunctional child seat of a two-wheeled vehicle, and the folding safety device can limit the folding locking member, and the elastic element is not a necessary component to improve the reliability of the folding mechanism.

[0007] The base member includes a front base and a rear base, the rear base is hinged to the front base through a folding mechanism, the longitudinal length of the rear base is less than the longitudinal length of the rear rack or rear cargo platform of the two-wheeled vehicle, and the front base is connected to the rear clothes rack of the two-wheeled vehicle. When the rear clothes rack of the two-wheeled vehicle is not sufficient to support and limit the rear base in the state of manned use, the front base can be installed in reverse so that the child sitting on it faces the rear of the vehicle. The longitudinal length of the rear base is less than the longitudinal length of the rear clothes rack of the two-wheeled vehicle, which ensures that when the first two-wheeled vehicle multifunctional child seat is installed in reverse, the front base is always fixed on the rear clothes rack of the two-wheeled vehicle. After reverse installation, the rear base can be supported and limited by the rear clothes rack of the two-wheeled vehicle. The length of different types of child seats is stipulated in the "Safety Requirements and Test Methods for Imported and Exported Bicycle Child Seats" (GB / T23160-2008), among which: the length of the A15 rear seat is between 160mm and 220mm, and the length of the A22 rear seat is between 170mm and 230mm. The length of the seat is less than the length of the rear hanger, so the maximum length of the rear base is determined to be between 160 and 230. The Safety Requirements for Child Seats for Bicycles is still under review, and the range of the maximum length of the rear base may change after the document is published.

[0008] The limiting frame includes a front vertical frame and a front longitudinal connecting piece. The front vertical frame is used to limit the forward flipping of the front enclosure, and is fixed to the front longitudinal connecting piece. The front longitudinal connecting piece is used to connect the front vertical frame and the folding mechanism, and the front longitudinal connecting piece is directly fixed to the folding mechanism, or indirectly fixed to the folding mechanism through the front base. The front vertical frame and the front longitudinal connecting piece can be hollow structures or solid structures, and their extension paths can be straight lines or curves. The front longitudinal connecting piece, the front vertical frame, the folding mechanism and the front base can be four parts integrally formed of the same material, or they can be a combination of parts of different materials.

[0009] The front enclosure member is used to form an enclosure for the front part of the first two-wheeled vehicle multifunctional child seat when in a loading state. The front enclosure member is hinged to the front base, and the forward flipping of the front enclosure member is limited by the front vertical frame.

[0010] The backrest is connected to the rear base, and after the backrest is folded forward and close to the front enclosure, the front enclosure, the front base, the rear base and the backrest together form an enclosure structure. The present invention is used outdoors in rainy and snowy weather, and making the backrest into an integrated waterproof style is conducive to long-term storage. However, many people are accustomed to covering parked vehicles with rain gear, so it is not necessary to make the backrest into an integrated waterproof style, and the holes in the backrest are sufficient to prevent the helmet from falling off.

[0011] The side wing members are connected to the left and right sides of the backrest member. The side wing members are used to enclose the enclosure structure formed by the front enclosure member, the front base, the rear base and the backrest member from the left and right sides. The degree to which the side wing members enclose the enclosure structure is not limited, as long as the helmet does not fall off. The side wing members and the backrest member can be two parts integrally formed of the same material, or a combination of two parts of the same material or different materials. When used outdoors, there will be rain and snow. Making the side wing members into an integrated waterproof style is conducive to long-term storage of items in the cargo-carrying use state, but many people are accustomed to covering parked vehicles with rain gear, so it is not necessary to make the side wing members into an integrated waterproof style.

[0012] A partial structure of the first two-wheeled vehicle multifunctional child seat is folded to form an enclosed space, and the folding locking piece is used to limit the folding mechanism, so that the first two-wheeled vehicle multifunctional child seat can have a carrying function. In the state of carrying, the front enclosure limits the forward flipping of the backrest, and the folding locking piece limits the backward flipping of the backrest, thereby realizing the reliable storage of items. In the state of carrying people, the folding locking piece is unlocked, the backrest is flipped backward until the rear base is limited by the rear clothes hanger of the two-wheeled vehicle, and then the front enclosure is placed on the front base, and the first two-wheeled vehicle multifunctional child seat enters the state of carrying people.

[0013] Furthermore, in order to solve the problem that the backrest part is not limited in forward flipping when the vehicle is in use with passengers, which is not conducive to the installation and use of the safety belt, the above technical solution is improved: the folding locking part and the card slot cooperate with each other, and the folding mechanism is limited in one direction when the vehicle is in use with passengers, thereby limiting the forward flipping of the backrest part, so that the first two-wheeled vehicle multifunctional child seat cannot be transformed from the vehicle state to the cargo state. The backrest part that is limited in forward flipping when the vehicle is in use with passengers can fix the safety belt. According to the different shapes of the folding locking part, the number of the card slots is not limited to one or two.

[0014] Optionally, in order to reduce the obstruction of the front base to the legs of the infant, the above technical solution is improved: the front base is divided into a front base moving part and a front base fixing part. One end of the front base moving part is hinged to the front enclosure, and the other end is hinged to the front base fixing part. The front base fixing part is hinged to the rear base through a folding mechanism. In the state of use for carrying goods, the front base moving part is supported by the front longitudinal connecting part. In the state of use for carrying people, the front base moving part and the front enclosure can be flipped backwards, and the front base moving part is placed above the rear base, and the front enclosure is limited by the backrest part to reduce the obstruction to the legs of the infant.

[0015] In order to eliminate the limitation of the environmental characteristics on the size of the rear base, according to one aspect of the present invention, a second two-wheeled vehicle multifunctional child seat is provided, comprising: a folding mechanism, a base member, a limit frame, a front barrier member, a backrest member and side wing members.

[0016] The folding mechanism includes a first folding member, a folding locking member and a second folding member. The folding locking member can be slidably arranged on the second folding member, or can be detachably connected to the second folding member, or can be hinged to the second folding member. A card slot is provided on the first folding member, and the card slot can cooperate with the folding locking member. When the folding mechanism is in a state of carrying people, the folding mechanism is limited in one direction to limit the unfolding angle; and when the folding mechanism is in a state of carrying goods, the second two-wheeled vehicle multifunctional child seat cannot be transformed into a state of carrying people. The folding locking member is designed to be tilted and slidably arranged on the second folding member, so that the folding mechanism can be self-locked; the folding locking member is designed to be hinged to the second folding member, and the center of gravity of the folding locking member can be used to achieve self-locking of the folding mechanism; the folding locking member with a thread is designed to be detachably connected to the second folding mechanism, so that the folding mechanism can be self-locked. Another aspect of the present invention also provides a folding safety device for a two-wheeled vehicle multifunctional child seat, which can limit the folding locking member, and the elastic element is not a necessary component to improve the reliability of the folding mechanism. It should be noted that: in the state of passenger use, the folding mechanism limits and supports the rear base, thereby ensuring that the second two-wheeled vehicle multifunctional child seat is always rideable no matter how it is installed on the two-wheeled vehicle, eliminating the restriction of the rear hanger of the two-wheeled vehicle on the length of the rear base.

[0017] The base member comprises a front base and a rear base, and the rear base is hinged to the front base via a folding mechanism.

[0018] The limiting frame includes a front vertical frame and a front longitudinal connecting piece. The front vertical frame is used to limit the forward flipping of the front enclosure, and is fixed to the front longitudinal connecting piece. The front longitudinal connecting piece is used to connect the front vertical frame and the folding mechanism, and the front longitudinal connecting piece is directly fixed to the folding mechanism, or indirectly fixed to the folding mechanism through the front base. The front vertical frame and the front longitudinal connecting piece can be hollow structures or solid structures, and their extension paths can be straight lines or curves. The front longitudinal connecting piece, the front vertical frame, the folding mechanism and the front base can be four parts integrally formed of the same material, or they can be a combination of parts of different materials.

[0019] The front enclosure member is used to form an enclosure for the front part of the first two-wheeled vehicle multifunctional child seat when in a loading state. The front enclosure member is hinged to the front base, and the forward flipping of the front enclosure member is limited by the front vertical frame.

[0020] The backrest is connected to the rear base. The maximum angle of the backrest to flip forward around the hinge point is limited by the front enclosure. After the backrest is folded forward and close to the front enclosure, the front enclosure, the front base, the rear base and the backrest together form an enclosure structure. The present invention will be exposed to rain and snow when used outdoors. Making the backrest into an integrated waterproof style is conducive to long-term storage of items, but many people are accustomed to covering parked vehicles with rain gear. Therefore, it is not necessary to make the backrest into an integrated waterproof style. It is sufficient that the holes in the backrest will not cause the helmet to fall off.

[0021] The side wing members are connected to the left and right sides of the backrest member. The side wing members are used to enclose the enclosure structure formed by the front enclosure member, the front base, the rear base and the backrest member from the left and right sides. The degree to which the side wing members enclose the enclosure structure is not limited, as long as the helmet does not fall off. The side wing members and the backrest member can be two parts integrally formed of the same material, or a combination of two parts of the same material or different materials. When used outdoors, there will be rain and snow. Making the side wing members into an integrated waterproof style is conducive to long-term storage of items in the cargo-carrying use state, but many people are accustomed to covering parked vehicles with rain gear, so it is not necessary to make the side wing members into an integrated waterproof style.

[0022] By folding part of the structure of the second two-wheeled vehicle multifunctional child seat to form an enclosed space and using the folding locking piece to limit the folding mechanism, the second two-wheeled vehicle multifunctional child seat can have a carrying function. In the state of carrying, the front enclosure limits the forward flipping of the backrest, and the folding locking piece and the card slot cooperate to limit the backward flipping of the backrest, so as to achieve the storage of items. In the state of carrying people, the folding locking piece and the card slot limit the backward flipping of the backrest, so as to achieve the riding of children.

[0023] Furthermore, the backrest is not limited in position when the passenger is in use, so that the safety belt lacks a fixed point, and the safety of children riding needs to be improved. To this end, the technical solution provided by the embodiment of the present invention is: designing a card slot that can cooperate with the folding locking member, so that the folding locking member and the card slot cooperate with each other, and a two-way limited folding mechanism is provided in the passenger state. The backrest that is limited in both directions in the passenger state can fix the safety belt. According to the different shapes of the folding locking member, the number of the card slots is not limited to one or two.

[0024] Optionally, in order to reduce the obstruction of the front base to the legs of the infant, the above technical solution is improved: the front base is divided into a front base moving part and a front base fixing part. One end of the front base moving part is hinged to the front enclosure, and the other end is hinged to the front base fixing part. The front base fixing part is hinged to the rear base through a folding mechanism. In the state of use for carrying goods, the front base moving part is supported by the front longitudinal connecting part. In the state of use for carrying people, the front base moving part and the front enclosure can be flipped backwards, and the front base moving part is placed above the rear base, and the front enclosure is limited by the backrest part to reduce the obstruction to the legs of the infant.

[0025] According to one aspect of the present invention, a third multifunctional child seat for a two-wheeled vehicle is provided, comprising a folding mechanism, a base member, a limit frame, a front enclosure member, a backrest member and side wing members.

[0026] The folding mechanism includes a first folding member, a folding locking member, and a second folding member. The folding locking member can be slidably arranged on the second folding member, or can be detachably connected to the second folding member, or can be hinged to the second folding member. A slot is provided on the first folding member, and the slot can cooperate with the folding locking member. In the state of carrying goods, the one-way limiting folding mechanism makes it impossible for the third two-wheeled vehicle multifunctional child seat to be transformed into a state of carrying people. One of the first folding member and the second folding member is provided with a positioning protrusion, and the other of the first folding member and the second folding member is provided with a positioning slot. The positioning protrusion and the positioning slot limit the maximum unfolding angle of the folding mechanism in the state of carrying people. In the state of carrying people, the positioning protrusion and the positioning slot limit the unfolding angle of the backrest member and the rear base, thereby ensuring that no matter how the seat is installed on the two-wheeled vehicle, the seat is always rideable, eliminating the influence of environmental characteristics. The folding locking piece is designed to be tilted and slidably arranged on the second folding piece, so that the folding mechanism can be self-locked; the folding locking piece is designed to be hinged to the second folding piece, and the center of gravity of the folding locking piece is used to achieve self-locking of the folding mechanism; the folding locking piece with threads is designed to be detachably connected to the second folding mechanism, so that the folding mechanism can be self-locked. Another aspect of the present invention also provides a folding safety device for a multifunctional child seat for a two-wheeled vehicle, which can limit the folding locking piece, and the elastic element is not a necessary component to improve the reliability of the folding mechanism. It should be particularly noted that sometimes the boundaries of the positioning protrusions and the positioning slots are relatively vague. First, take the first embodiment of the third multifunctional child seat for two-wheeled vehicle as an example: Fig.21 The positioning slot is set in the second folding member, but the cross-sectional shape of the second folding member alone does not show the existence of a slot-style structure. Fig.19 It can be seen from the positioning slot in Fig.21 Secondly, from another perspective, when the positioning protrusion and the first folding member are taken as a whole, they can be regarded as a three-dimensional slot structure, and when the positioning slot and the second folding member are taken as a whole, they can be regarded as a two-dimensional protrusion structure.

[0027] The base member comprises a front base and a rear base, and the rear base is hinged to the front base via a folding mechanism.

[0028] The limiting frame includes a front vertical frame and a front longitudinal connecting piece. The front vertical frame is used to limit the forward flipping of the front enclosure, and is fixed to the front longitudinal connecting piece. The front longitudinal connecting piece is used to connect the front vertical frame and the folding mechanism, and the front longitudinal connecting piece is directly fixed to the folding mechanism, or indirectly fixed to the folding mechanism through the front base. The front vertical frame and the front longitudinal connecting piece can be hollow structures or solid structures, and their extension paths can be straight lines or curves. The front longitudinal connecting piece, the front vertical frame, the folding mechanism and the front base can be four parts integrally formed of the same material, or they can be a combination of parts of different materials.

[0029] The front enclosure member is used to form an enclosure for the front part of the first two-wheeled vehicle multifunctional child seat when in a loading state. The front enclosure member is hinged to the front base, and the forward flipping of the front enclosure member is limited by the front vertical frame.

[0030] The backrest member is connected to the rear base. The maximum angle of the backrest member to flip forward around the hinge point is limited by the front enclosure member. After the backrest member is folded forward and close to the front enclosure member, the front enclosure member, the front base, the rear base and the backrest member together form an enclosure structure. The side wing members are connected to the left and right sides of the backrest member. The side wing members are used to enclose the enclosure structure formed by the front enclosure member, the front base, the rear base and the backrest member from the left and right sides. The degree of enclosure of the enclosure structure by the side wing members is not limited as long as the helmet does not fall off. The side wing members and the backrest member can be two parts integrally formed of the same material, or can be a combination of two parts of the same material or different materials.

[0031] The third type of two-wheeled vehicle multifunctional child seat is partially folded to form an enclosed space, and the folding locking piece is used to limit the position, and the third type of two-wheeled vehicle multifunctional child seat enters the cargo-carrying use state. At this time, the front enclosure limits the forward folding of the backrest, and the folding locking piece and the card slot limit the backward folding of the backrest. The positioning protrusion and the positioning card slot limit the maximum angle of the folding mechanism, which supports the rear base, so that the child can sit in the passenger-carrying use state.

[0032] Furthermore, the forward folding of the backrest member in the state of passenger use is not limited, resulting in a lack of fixing points for the safety belt, and the safety of children riding in the seat needs to be improved. To this end, the technical solution provided by the embodiment of the present invention is: a card slot that can cooperate with the folding locking member is designed, so that the folding locking member and the card slot cooperate with each other, and the one-way limited folding mechanism in the state of passenger use prevents the seat from being converted to the state of cargo use. The backrest member that is limited in the forward flipping state of passenger use can fix the safety belt. Depending on the shape of the folding locking member, the number of card slots is not limited to one or two.

[0033] Optionally, in order to reduce the obstruction of the front base to the legs of the infant, the above technical solution is improved: the front base is divided into a front base moving part and a front base fixing part. One end of the front base moving part is hinged to the front enclosure, and the other end is hinged to the front base fixing part. The front base fixing part is hinged to the rear base through a folding mechanism. In the state of use for carrying objects, the front base moving part is supported by the front longitudinal connecting part. In the state of use for carrying people, the front base moving part and the front enclosure can be flipped backwards, the front base moving part is placed above the rear base, and the front enclosure is limited by the backrest part to reduce the obstruction to the legs of the infant.

[0034] When storing items for a long time in a state of carrying goods, the problem of how to prevent theft needs to be considered; when the folding locking member limit folding mechanism is used in a state of carrying people, the problem of accidental unlocking may occur. To this end, according to another aspect of the present invention, a folding safety device for a two-wheeled vehicle multifunctional child seat is provided, comprising: a rear pull rod, front and rear connecting rods, a rear longitudinal connecting member, a transverse connecting member, a lock body, a lock plate, and a two-wheeled vehicle multifunctional child seat according to any one of claims 1 to 9.

[0035] The rear longitudinal connecting member is fixed to the folding mechanism and is used to install the rear pull rod. The rear longitudinal connecting member can be a hollow structure or a solid structure, and its extension path can be a straight line or a curve.

[0036] The rear pull rod is slidably arranged on the rear longitudinal connecting member and is indirectly connected to the folding locking member through the front and rear connecting rods of the locking member. The front and rear connecting rods connect the folding locking member and the rear pull rod, and the movement of the folding locking member is transmitted to the rear pull rod through the front and rear connecting rods.

[0037] The lock body is fixed to the transverse connecting member to realize the anti-theft function. The locking plate is connected to the lock body to directly or indirectly limit the position of the folding locking member. The locking plate is used to limit the rear pull rod or the front and rear connecting rods to indirectly limit the position of the folding locking member.

[0038] The introduction of the transverse connector provides a wider range of fixing points for the lock body. When the number of rear longitudinal connectors is more than one, the transverse connector can simultaneously connect multiple rear longitudinal connectors to reinforce the seat.

[0039] When the folding locking piece slides longitudinally, the rear pull rod is driven by the front and rear connecting rods to slide longitudinally forward and backward; when the folding locking piece rotates around the hinge point, the rear pull rod is driven by the front and rear connecting rods to slide forward and backward; when the folding locking piece slides laterally, the rear pull rod is driven by the front and rear connecting rods to slide laterally left and right; when the folding locking piece is screwed into the first folding piece, the rear connecting rod is sleeved on the folding locking piece. At this time, the rear pull rod and the front and rear connecting rods do not rotate, and the rear pull rod is driven by the front and rear connecting rods to slide laterally.

[0040] The introduction of the folding safety device can not only realize the anti-theft storage of the items on the vehicle when it is used for carrying goods, but also prevent the folding mechanism from being accidentally unlocked when it is used for carrying people.

[0074] For the convenience of description, the terms "front", "rear", "left" and "right" are determined based on the first-person perspective of the child when sitting, and have nothing to do with the left-right direction of the drawings. For the sake of simplicity, the multifunctional child seat for a two-wheeled vehicle provided in the following embodiments may be referred to as a "seat".

[0075] 1. The first embodiment of the multifunctional child seat for a two-wheeled vehicle

[0076] like Figure 1 As shown, this embodiment provides a multifunctional child seat for a two-wheeled vehicle, comprising: a folding mechanism 1, a base member 2, a limit frame 3, a front enclosure member 4, a backrest member 5 and a side wing member 6.

[0077] like Figure 2As shown, the base member 2 includes a front base 21 and a rear base 22, and the front base 21 and the rear base 22 are hinged by a folding mechanism 1. The rear base 22, the backrest member 5, and the side wing member 6 can be folded forward together by swinging. There are two side wing members 6, which are respectively connected to the left and right sides of the backrest member 5. The backrest member 5 is connected to the rear end of the rear base 22, and the front enclosure member 4 is hinged to the front base 21. The limiting frame 3 includes a front vertical frame 31 and a front longitudinal connecting member 32. The front vertical frame 31 is fixed to the front longitudinal connecting member 32, and the front longitudinal connecting member 32 is directly fixed to the folding mechanism 1.

[0078] like Figure 3 As shown, the folding mechanism 1 includes a first folding member 11, a second folding member 12 and a folding locking member 13. The folding locking member 13 is slidably connected to the second folding member 12. The first folding member 11 is provided with a slot 14, which can cooperate with the folding locking member 13. When the seat is used for carrying objects, the one-way limit folding mechanism 1 prevents the seat from being transformed into a state for carrying people. The presence of the front enclosure 4 limits the maximum angle of the backrest member 5 to be folded forward. When the seat is used for carrying objects, the folding locking member 13 can be operated to enter the slot 14 to store the items on the vehicle.

[0079] In this embodiment, the seat can be installed forward, and the child sitting in the child seat faces the front of the two-wheeled vehicle when the child seat is used with passengers, and the front base 21 is connected to the rear hanger of the two-wheeled vehicle. If the seat is installed forward, the length of the rear hanger of the two-wheeled vehicle is not enough to support and limit the rear base 22 when the child seat is used with passengers, and the seat can be installed in reverse. The longitudinal length of the rear base 22 is less than the longitudinal length of the rear hanger of the two-wheeled vehicle, which ensures that when the child seat of the embodiment of the present invention is installed in reverse with the passenger facing backward, the front base 21 is always fixed to the rear hanger of the two-wheeled vehicle, and the rear base 22 can be supported and limited by the rear hanger of the two-wheeled vehicle.

[0080] In this embodiment, the number of the first folding member 11, the second folding member 12 and the limiting frame 3 are all two, and the number of the folding locking member 13 is one, and its cross section is circular. The folding locking member 13 is slidably arranged on the second folding member 12, and the folding locking member 13 can slide longitudinally forward and backward on the second folding member 12. In this embodiment, the direction in which the folding locking member 13 slides forward and backward has a certain inclination, and the folding locking member 13 can be inserted into the card slot 14 and maintain its position under the action of gravity. When the rear base 22 is folded forward, the second folding member 12 and the folding locking member 13 flip forward together with the rear base 22 around the hinge point.

[0081] In this embodiment, the first folding member 11 and the front base 21, the second folding member 12 and the rear base 22, the front vertical frame 31 and the front longitudinal connecting member 32, the front base 21 and the front longitudinal connecting member 32, the backrest member 5 and the side wing member 6 are all integrally formed with the same material. The maximum forward turning angle of the front enclosure member 4 is limited by the front vertical frame 31.

[0082] The seat provided in this embodiment has two use states, one is the use state of carrying people, such as Figure 2 As shown, the other is the cargo use state, such as Figure 3 The specific process of the two state transitions is as follows:

[0083] In the passenger-carrying state, the folding locking member 13 is unlocked, and the backrest member 5 is pushed to make the second folding member 12, the folding locking member 13, the rear base 22, the backrest member 5, and the side wing member 6 fold forward together by swinging. When the backrest member 5 is folded and close to the front enclosure member 4, the front enclosure member 4, the front base 21, the rear base 22, the backrest member 5, and the side wing member 6 form an enclosure structure together. After the second folding member 12 and the folding locking member 13 are flipped around the hinge point, the folding locking member 13 slides on the second folding member 12 under the action of gravity and is embedded in the slot 14 of the first folding member 11, so that the folding mechanism 1 is locked. At this time, the backrest member 5, the rear base 22, and the side wing member 6 are all limited, and the seat enters the cargo-carrying state.

[0084] In the cargo-carrying state, pull the folding locking member 13 and fold the backrest member 5 backward until the rear base 22 is supported by the rear clothes hanger of the two-wheeled vehicle, and then fold the front enclosure member 4 backward and place it on the front base 21 to put the rear seat into the passenger-carrying state.

[0085] 2. Second embodiment of the first multifunctional child seat for two-wheeled vehicles

[0086] like Figure 4 As shown, this embodiment provides a multifunctional child seat for a two-wheeled vehicle, comprising: a folding mechanism 1, a base member 2, a limit frame 3, a front enclosure member 4, a backrest member 5 and a side wing member 6.

[0088] like Figure 4 As shown, the folding mechanism 1 includes a first folding member 11, a second folding member 12, and a folding locking member 13. The folding locking member 13 is detachably connected to the second folding member 12. A slot 14 is provided on the first folding member 11, and the slot 14 can cooperate with the folding locking member 13 to limit the folding mechanism 1 in a one-way position in the state of carrying objects, so that the seat cannot be transformed into a state of carrying people. After the backrest member 5 is folded forward, the folding locking member 13 is twisted to be inserted into the slot 14, and then the folding mechanism 1 is locked to store the articles on the vehicle.

[0089] The difference between this embodiment and the first embodiment of the first two-wheeled vehicle multifunctional child seat mentioned above is that: the front base 21 and the front longitudinal connecting member 32, the front vertical frame 31 and the front longitudinal connecting member 32 of this embodiment are respectively composed of two parts made of different materials; the folding locking member 13 is a bolt, which is detachably connected to the second folding member 12; the number of the slots 14 on a single first folding member 11 is one; the slots 14 and the folding locking member 13 can cooperate with each other to limit the folding mechanism 1 in the passenger-carrying state, so that the seat cannot be transformed into the cargo-carrying state.

A slot 14 is provided on the first folding member 11, and the slot 14 can cooperate with the folding locking member 13 to limit the folding mechanism 1 in a one-way position in the state of carrying objects, so that the seat cannot be transformed into a state of carrying people. The presence of the front enclosure member 4 limits the maximum angle of the backrest member 5 to be folded forward. After the backrest member 5 is folded forward, the folding locking member 13 is operated to lock the folding mechanism 1 so that the articles accompanying the vehicle can be stored.

[0094] The main difference between the first embodiment of the first two-wheeled vehicle multifunctional child seat mentioned above is that the folding locking piece 13 of this embodiment is hinged to the second folding piece 12, and the folding locking piece 13 realizes the limiting function by swinging into the slot 14 on the first folding piece 11 under the action of gravity; the front base 21 of this implementation includes a front base moving piece 211 and a rear base moving piece 212, and the rear base fixing piece 212 and the first folding piece 11 are two parts of different materials connected to each other; the front vertical frame 31 and the front longitudinal connecting piece 32 of this embodiment are integrally formed.
