Description

TECHNICAL FIELD

[0001] The present application relates to the field of child seats, in particular to a multifunctional child seat for a two-wheeled vehicle and a folding security device thereof. BACKGROUND

[0002] After a rear safety seat is installed on an electric bicycle, a trunk cannot be installed, and a safety helmet loses a safe storage space, which also limits the willingness to use high-quality safety helmets. The willingness to use a front basket of a bicycle is not high, on the one hand, the front basket affects the steering feeling after loading, and on the other hand, the front basket is not very beautiful. After a bicycle is installed with a fixed seat on a rear loading rack, the helmet also faces the problem of no place to store. SUMMARY

[0003] In order to solve the problem that a two-wheeled vehicle such as a bicycle or an electric bicycle cannot simultaneously install a rear child seat for carrying people and a rear trunk for carrying things, the present application provides a multifunctional child seat for a two-wheeled vehicle and a folding security device thereof. By folding part of the structure of the multifunctional child seat for a two-wheeled vehicle to form an enclosed space and using the folding security device to lock the folding locking member, the multifunctional child seat for a two-wheeled vehicle has a carrying function, achieving the effect of one thing serving two purposes.

[0004] According to one aspect of the present application, a multifunctional child seat for a two-wheeled vehicle (first type) is provided, comprising a folding mechanism, a base member, a front barrier member, a backrest member, and a side wing member.

[0005] The folding mechanism comprises a first folding member, a folding locking member, and a second folding member. The folding locking member is slidably arranged on the second folding member, or hinged to the second folding member, or detachably connected to the second folding member. A clamping groove is provided on the first folding member, which can cooperate with the folding locking member to one-way limit the folding mechanism in a carrying use state, so that the multifunctional child seat for a two-wheeled vehicle cannot be changed to a people-carrying use state. It should be noted that the folding locking member is designed to be inclined and slidably arranged on the second folding member, which can realize self-locking of the folding mechanism; 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 realize self-locking of the folding mechanism; the folding locking member with threads can be detachably connected to the second folding mechanism, which can also realize self-locking of the folding mechanism. Another aspect of the present application further provides a folding security device for a multifunctional child seat for a two-wheeled vehicle, which can limit the folding locking member, and the elastic element is not a necessary component to improve the reliability of the folding mechanism.

[0006] The base piece comprises 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 non-motorized vehicle rear shelf or rear platform, and the front base is connected to the rear rack of the two-wheeled vehicle. When the rear rack of the two-wheeled vehicle is insufficient to support and limit the rear base in the state of carrying a person, the front base can be installed reversely, so that the child sitting faces the tail of the vehicle. The longitudinal length of the rear base is less than the longitudinal length of the rear rack of the two-wheeled vehicle, which ensures that the front base is always positioned on the rear rack of the two-wheeled vehicle when the multifunctional child seat (first type) of the two-wheeled vehicle is installed reversely. After reverse installation, the rear base can be supported and limited by the rear rack of the two-wheeled vehicle. The length of different types of child seats is specified in "Safety Requirements and Test Methods for Exported Bicycle Child Seats" (GB / T 23160-2008), wherein: 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 rack, and the maximum length of the rear base determined thereby is between 160 and 230. "Safety Requirements for Bicycle Child Seats" is still under review, and the range of the maximum length of the rear base may change after the document is issued.

[0007] The front wall piece is used to form a wall in front of the multifunctional child seat (first type) of the two-wheeled vehicle in the state of carrying an object, and the front wall piece is hinged to the front base through a rotating shaft or a hinge, and the front wall piece is limited by the rotating shaft or the hinge when it is flipped forward; the front wall piece can be flipped backward until it is attached to the front base in the state of carrying a person. It should be noted that the front wall piece is hinged to the front base by a common hinge, and the design of the hinge center position can limit the front wall piece by the front base. At this time, the hinge together with a part of the front wall piece and a part of the front base should be regarded as a rotating shaft with limiting function. The hinge specifically refers to a composite hinge in which two or more components are connected by rotating pairs at the same place.

[0008] The backrest piece is connected to the rear base, and after the backrest piece is flipped forward to approach the front wall piece, the front wall piece, the front base, the rear base, and the backrest piece form a closed structure together. When this application is used outdoors, it will face rainy and snowy weather, and making the backrest piece into an integrated waterproof style is beneficial for long-term storage of objects, but many people are used to shielding parked vehicles with rain gear, so it is not necessary to make the backrest piece into an integrated waterproof style. The holes of the backrest piece can not fall off the helmet.

[0009] The side wings are connected to the left and right sides of the backrest. The side wings are used to enclose the enclosure structure formed by the front baffle, front base, rear base, and backrest from both sides. The degree of enclosure provided by the side wings is not limited, as long as the helmet does not fall off. The side wings and backrest can be two parts integrally formed from the same material, or they can be a combination of two parts made of the same or different materials.

[0010] When used outdoors, vehicles will encounter rain and snow. Making the side wings one-piece waterproof is beneficial for storing items for a long time when carrying cargo. However, many people are used to covering their parked vehicles with rain gear, so making the side wings one-piece waterproof is not necessary.

[0011] A folding mechanism of a multi-functional child seat for a two-wheeled vehicle (Type I) creates an enclosed space. A folding lock limits the folding mechanism, enabling the seat to carry cargo. In cargo-carrying mode, the front bumper prevents the backrest from folding forward, and the folding lock prevents the backrest from folding backward, ensuring reliable storage of items. In passenger-carrying mode, the folding lock is unlocked, the backrest folds backward until it is stopped by the rear coat rack of the two-wheeled vehicle, and then the front bumper is placed on the front base, thus activating the passenger-carrying mode.

[0012] Furthermore, to address the issue of the backrest not being restricted from forward rotation during passenger use, which hinders the installation and use of seat belts, the above technical solution is improved: the folding locking component cooperates with the slot to unidirectionally restrict the folding mechanism during passenger use, thereby limiting the forward rotation of the backrest and preventing the two-wheeled multi-functional child seat (Type 1) from transitioning from passenger use to cargo use. The backrest, bidirectionally restricted during passenger use, can secure the seat belt. Depending on the shape of the folding locking component, the number of slots is not limited to one or two.

[0013] To eliminate the limitations imposed by environmental characteristics on the size of the rear base, according to one aspect of this application, a two-wheeled vehicle multi-functional child seat (Type II) is provided, comprising: a folding mechanism, a base member, a front panel member, a backrest member, and side wings.

[0014] The folding mechanism comprises a first folding member, a folding locking member and a second folding member. The folding locking member is slidably arranged on the second folding member, or detachably connected to the second folding member, or hingedly connected to the second folding member. The first folding member is provided with a clamping groove capable of cooperating with the folding locking member to one-way limit the folding mechanism in the passenger carrying state, thereby limiting the unfolding angle of the folding mechanism; and one-way limit the folding mechanism in the object carrying state, thereby preventing the second type of two-wheeled vehicle multifunctional child seat from being converted to the passenger carrying state. The folding locking member is designed to be obliquely slid on the second folding member, thereby achieving self-locking of the folding mechanism; the folding locking member is designed to be hingedly connected to the second folding member, thereby achieving self-locking of the folding mechanism by using the center of gravity of the folding locking member; and the folding locking member with threads is designed to be detachably connected to the second folding mechanism, thereby also achieving self-locking of the folding mechanism. Another aspect of the present application also provides a folding insurance device for the two-wheeled vehicle multifunctional child seat, which can limit the folding locking member, and the elastic element is not a necessary component for improving the reliability of the folding mechanism. It should be noted that in the passenger carrying state, the folding mechanism limits and supports the rear base, thereby ensuring that the second type of two-wheeled vehicle multifunctional child seat always has the seatability regardless of how it is installed on a non-motor vehicle, and eliminating the limitation of the rear shelf of the two-wheeled vehicle on the length of the rear base.

[0015] The base member comprises a front base and a rear base, and the rear base is hingedly connected to the front base through the folding mechanism.

[0016] The front wall member is used for forming a front wall of the first type of two-wheeled vehicle multifunctional child seat in the object carrying state, and the front wall member is hingedly connected to the front base through a rotating shaft or a hinge, and the front wall member is limited by the rotating shaft or the hinge when being flipped forward; the front wall member can be flipped backward until being attached to the front base in the passenger carrying state. It should be noted that the front wall member is hingedly connected to the front base through a common hinge, and the hinge center position is designed to limit the front wall member by the front base, and at this time, the hinge together with a part of the front wall member and a part of the front base should be regarded as a rotating shaft with a limiting function. The hinge specifically refers to a composite hinge in which two or more components are connected through rotating pairs at the same place.

[0017] The backrest member is connected to the rear base. The maximum angle of the backrest member flipped forward around the hinge point is limited by the front wall member, and the front wall member, the front base, the rear base and the backrest member form a closed structure after the backrest member is flipped forward close to the front wall member. The backrest member is made in an integrated waterproof style when the present application is used outdoors, which is beneficial for long-term storage of objects, but many people are used to shielding the parked vehicle with rain gear, so it is not necessary to make the backrest member in an integrated waterproof style, and the hole of the backrest member can not drop the helmet.

[0018] The side wing member is connected to the left and right sides of the backrest member. The side wing member is used to block the surrounding structure formed by the front wall member, the front base, the rear base and the backrest member from the left and right sides. The blocking degree of the side wing member to the surrounding structure is not limited, and the helmet will not fall off. The side wing member and the backrest member can be two parts of the same material integrally formed, or two parts of the same material or different materials combined. When used outdoors, it will face rainy and snowy weather. Making the side wing member into an integrated waterproof style is beneficial for long-term storage of articles in the article carrying state, but many people are used to shielding the parked vehicle with rain gear, so it is not necessary to make the side wing member into an integrated waterproof style.

[0019] The part structure of the folding type multifunctional child seat (second type) forms a surrounding space and uses a folding locking member to limit the folding mechanism, so that the folding type multifunctional child seat (second type) has an article carrying function. In the article carrying state, the front wall member limits the forward folding of the backrest member, and the folding locking member cooperates with the clamping groove to limit the backward folding of the backrest member, thereby realizing the storage of articles. In the passenger carrying state, the folding locking member limits the backward folding of the backrest member, thereby realizing the seating of the child.

[0020] Further, the position of the center of the hinge between the first folding member and the second folding member in the passenger carrying state affects the size of the gap between the front base and the rear base in the article carrying state. When the position of the center of the hinge is higher than the upper end surface of the base member, pushing the backrest member to fold forward will make the front base and the rear base move away from each other and the gap become larger, which is not conducive to the storage of articles with the vehicle. Therefore, the above technical solution is further improved: the position of the center of the hinge between the first folding member and the second folding member is designed to be not higher than the upper end surface of the base member in the passenger carrying state. In this way, after the backrest member is folded forward, the relative position of the front base and the rear base will be further reduced or unchanged. Specifically, when the center of the hinge between the first folding member and the second folding member is between the upper and lower end surfaces of the base member: the parts of the front base and the rear base that are higher than the hinge point move closer to each other; the parts of the front base and the rear base that are lower than the hinge point move away from each other. Designing the position of the center of the hinge between the first folding member and the second folding member to be not higher than the upper end surface of the base member can reduce the gap between the front base and the rear base in the article carrying state, which is conducive to the storage of small articles.

[0021] Further, in the passenger carrying state, the backrest member is not limited, so that the safety belt lacks a fixed point, and the safety of the child when sitting needs to be improved. Therefore, the technical solution provided by the embodiments of the present application is to design a clamping groove that can cooperate with the folding locking member, so that the folding locking member and the clamping groove cooperate with each other to limit the folding mechanism in both directions in the passenger carrying state. The backrest member limited in both directions in the passenger state can fix the safety belt. According to the shape of the folding locking member, the number of clamping grooves is not limited to one or two.

[0022] According to one aspect of the present application, a multifunctional child seat for a two-wheeled vehicle (type III) is provided, comprising a folding mechanism, a base member, a front wall member, a backrest member, and a side wing member.

[0023] The folding mechanism comprises a first folding member, a folding lock member, and a second folding member. The folding lock member is slidably arranged on the second folding member, detachably connected to the second folding member, or hingedly connected to the second folding member. The first folding member is provided with a clamping groove capable of cooperating with the folding lock member to unidirectionally limit the folding mechanism in a load-carrying use state, so that the multifunctional child seat for a two-wheeled vehicle (type III) cannot be converted to a passenger-carrying use state. One of the first folding member and the second folding member is provided with a positioning protrusion, and the other is provided with a positioning clamping groove, which limits the maximum unfolding angle of the folding mechanism in the passenger-carrying use state. In the passenger-carrying use state, the positioning protrusion and the positioning clamping groove limit the unfolding angle of the backrest member and the rear base, thereby ensuring that the seat is always rideable regardless of how it is installed on a non-motorized vehicle, eliminating the influence of environmental features. The folding lock member is designed to be obliquely arranged on the second folding member, so that the folding mechanism can be self-locked. The folding lock member is designed to be hingedly connected to the second folding member, so that the folding mechanism can be self-locked by using the center of gravity of the folding lock member. The folding lock member is designed to be detachably connected to the second folding mechanism by means of a screw thread, so that the folding mechanism can also be self-locked. Another aspect of the present application also provides a folding safety device for a multifunctional child seat for a two-wheeled vehicle, which can limit the folding lock member, and the elastic element is not a necessary component for improving the reliability of the folding mechanism.

[0024] The base member comprises a front base and a rear base, and the rear base is hingedly connected to the front base by means of the folding mechanism.

[0025] The front wall member is used to form a barrier in front of the multifunctional child seat for a two-wheeled vehicle (type I) in a load-carrying use state. The front wall member is hingedly connected to the front base by means of a pivot or a hinge, and the front wall member is limited by the pivot or the hinge when it is flipped forward. In a passenger-carrying use state, the front wall member can be flipped backward until it is attached to the front base. It should be noted that the front wall member is hingedly connected to the front base by means of a common hinge, and the design of the hinge center position can limit the front wall member by the front base. At this time, the hinge together with a part of the front wall member and a part of the front base should be regarded as a pivot with a limiting function. The hinge specifically refers to a composite hinge in which two or more components are connected by a rotary pair at the same place.

[0026] The backrest is connected with the rear base. The maximum angle of the backrest being flipped forward around the hinge point is limited by the front wall. When the backrest is flipped forward close to the front wall, the front wall, the front base, the rear base and the backrest form a closed structure. The side wings are connected to the left and right sides of the backrest. The side wings are used to block the closed structure formed by the front wall, the front base, the rear base and the backrest from the left and right sides. The blocking degree of the side wings to the closed structure is not limited, and the helmet cannot fall off.

[0027] The part structure of the two-wheeled vehicle multifunctional child seat (the third type) is flipped to form a closed space, and a folding locking piece is used for limiting, so that the two-wheeled vehicle multifunctional child seat (the third type) enters a load carrying state. At this time, the front wall limits the forward folding of the backrest, and the folding locking piece and the clamping groove limit the rearward folding of the backrest. The positioning protrusion and the positioning clamping groove limit the maximum angle of the folding mechanism being unfolded, and support the rear base, so that the child can be seated in the load carrying state.

[0028] Further, the position of the center of the hinge between the first folding piece and the second folding piece in the load carrying state affects the size of the gap between the front base and the rear base in the load carrying state. When the position of the center of the hinge is higher than the upper end surface of the base, the forward folding of the backrest will make the front base and the rear base move away from each other and the gap become larger, which is not conducive to the storage of articles carried with the vehicle. Therefore, the above technical solution is further improved: the position of the center of the hinge between the first folding piece and the second folding piece is designed to be not higher than the upper end surface of the base in the load carrying state. In this way, after the backrest is flipped forward, the relative position of the front base and the rear base will be further reduced or unchanged. Specifically, when the center of the hinge between the first folding piece and the second folding piece is between the upper and lower end surfaces of the base, the parts of the front base and the rear base that are higher than the hinge point move close to each other, and the parts of the front base and the rear base that are lower than the hinge point move away from each other. Designing the position of the center of the hinge between the first folding piece and the second folding piece to be not higher than the upper end surface of the base can reduce the gap between the front base and the rear base in the load carrying state, which is conducive to the storage of small articles.

[0029] Further, in the load carrying state, the forward folding of the backrest is not limited, so that the safety belt lacks a fixed point, and the safety of the child when sitting is to be improved. Therefore, the technical solution provided by the embodiments of the present application is to design a clamping groove that can cooperate with the folding locking piece, so that the folding locking piece and the clamping groove cooperate with each other to limit the folding mechanism in both directions in the load carrying state. The backrest limited in both directions in the load carrying state can fix the safety belt. According to the shape of the folding locking piece, the number of clamping grooves is not limited to one or two.

[0030] Optionally, a lifting structure is introduced to adjust the height of the backrest to adapt to children of different heights. Specifically, in some embodiments, it further comprises: a rear vertical fixed frame, a rear vertical moving frame, and a lifting locking member.

[0031] The rear vertical fixed frame is provided with a first limiting hole. The rear vertical fixed frame can be directly connected to the rear base or indirectly connected to the rear base through other components. For example, the rear vertical fixed frame is directly connected to the first folding member or the second folding member, thereby indirectly connecting the rear base. The rear vertical fixed frame and the rear base can be two parts integrally formed of the same material.

[0032] The rear vertical moving frame is slidably arranged in the rear vertical fixed frame, and the rear vertical moving frame is provided with a second limiting hole. The backrest member is fixed to the rear vertical moving frame. The rear vertical moving frame and the backrest member can be two parts integrally formed of the same material, or can be two parts combined of the same material or different materials.

[0033] The lifting locking member comprises a lifting locking member body, a locking pin, and an elastic member. The lifting locking member body is fixed to the backrest member. The lifting locking member body and the backrest member can be two parts integrally formed of the same material, or can be two parts combined of the same material or different materials. The locking pin is slidably arranged in the lifting locking member body, and the locking pin is simultaneously embedded in the first limiting hole and the second limiting hole under the action of the elastic member, thereby achieving the lifting locking function. The backrest member with adjustable height provides more sufficient back support for children. The side wing member is lifted together with the backrest member. When the position of the backrest member is sufficient to support the head of the child, the side wing member can also protect the head of the child from the side.

[0034] In the state of loading objects, the problem of how to prevent theft needs to be considered. In the state of loading people, the folding locking member may have the problem of accidental unlocking. Therefore, according to another aspect of the present application, a folding insurance device for a multifunctional child seat of a two-wheeled vehicle is provided, which comprises a rear pull rod, a front-rear connecting rod, a longitudinal connecting member, a transverse connecting member, a lock body, a lock plate, and a two-wheeled vehicle multifunctional child seat provided with the folding insurance device.

[0035] The longitudinal connecting member is fixed to the folding mechanism and used to mount the rear pull rod. The 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 in the longitudinal connecting member and indirectly connected to the folding locking member through the locking member front-rear connecting rod. The front-rear connecting rod is a rigid member used to connect the folding locking member and the rear pull rod. The movement of the folding locking member is transmitted to the rear pull rod through the front-rear connecting rod.

[0037] The lock body is fixed to the transverse connecting piece for realizing the anti-theft function. The lock piece is connected to the lock body for directly or indirectly limiting the folding locking piece. The rear pull rod or the front-rear connecting rod is limited by the lock piece, and the folding locking piece is indirectly limited.

[0038] The introduction of the transverse connecting piece provides a wider fixing point for the lock body. When the number of longitudinal connecting pieces is more than one, the transverse connecting piece simultaneously connects multiple longitudinal connecting pieces, which can reinforce the seat.

[0039] When the folding locking piece slides longitudinally, the rear pull rod is driven by the front-rear connecting rod to slide longitudinally; when the folding locking piece rotates around the hinge point, the rear pull rod is driven by the front-rear connecting rod to slide longitudinally; when the folding locking piece slides transversely, the rear pull rod is driven by the front-rear connecting rod to slide transversely; when the folding locking piece is rotated 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-rear connecting rod do not rotate, and the rear pull rod is driven by the front-rear connecting rod to slide transversely.

[0040] The introduction of the folding locking device can realize the anti-theft storage of the articles on the vehicle in the article carrying state, and can prevent the folding mechanism from being accidentally unlocked in the passenger carrying state. BRIEF DESCRIPTION OF DRAWINGS

[0079] For the convenience of description, the following "front", "rear", "left" and "right" are determined according to the first perspective when a child is seated, and are irrelevant to the left and right directions of the drawings. For the sake of brevity, the multifunctional child seat of a non-motor vehicle provided in the following embodiments can be referred to as "seat".

[0080] 1. A first embodiment of a two-wheeled vehicle multifunctional child seat (the first type)

[0081] As shown in Fig. 1, the present embodiment provides a multifunctional child seat of a non-motor vehicle, which comprises a folding mechanism 1, a base 2, a front barrier 3, a backrest 4 and side wings 5. Figure 1 As shown in Fig. 2, the base 2 comprises a front base 21 and a rear base 22, which are hinged by the folding mechanism 1. The rear base 22, the backrest 4 and the side wings 5 can be folded forward together by swinging. The side wings 5 are two in number and are connected to the left and right sides of the backrest 4, respectively. The backrest 4 is connected to the rear end of the rear base 22, and the front barrier 3 is connected to the front base 21 by a rotating shaft 31.

[0082] Figure 2 As shown in Fig. 3, the base 2 comprises a front base 21 and a rear base 22, which are hinged by the folding mechanism 1. The rear base 22, the backrest 4 and the side wings 5 can be folded forward together by swinging. The side wings 5 are two in number and are connected to the left and right sides of the backrest 4, respectively. The backrest 4 is connected to the rear end of the rear base 22, and the front barrier 3 is connected to the front base 21 by a rotating shaft 31.

[0083] As shown in Fig. 4, the base 2 comprises a front base 21 and a rear base 22, which are hinged by the folding mechanism 1. The rear base 22, the backrest 4 and the side wings 5 can be folded forward together by swinging. The side wings 5 are two in number and are connected to the left and right sides of the backrest 4, respectively. The backrest 4 is connected to the rear end of the rear base 22, and the front barrier 3 is connected to the front base 21 by a rotating shaft 31. Figure 3 ​As shown, the folding mechanism 1 includes a first folding piece 11, a second folding piece 12, and a folding locking piece 13. The folding locking piece 13 is slidably connected to the second folding piece 12, and the first folding piece 11 is provided with a clamping groove 14 capable of cooperating with the folding locking piece 13. In the object-carrying state, the folding mechanism 1 is unidirectionally limited, so that the seat cannot be converted to the human-carrying state. The presence of the front wall blocking piece 3 limits the maximum angle of forward folding of the backrest piece 4. In the object-carrying state, the folding locking piece 13 can be operated to enter the clamping groove 14 to achieve the storage of the objects on the vehicle.

[0084] In the embodiment, the seat is installed in the forward direction, and in the human-carrying state, the child sitting on the seat faces the front of the scooter. The front base 21 is connected to the rear carrier of the scooter. If the seat is installed in the forward direction, the length of the rear carrier of the scooter is insufficient to support and limit the rear base 22 in the human-carrying state. At this time, the seat can be installed in the reverse direction. The longitudinal length of the rear base 22 is less than the longitudinal length of the rear carrier of the scooter, so that the front base 21 of the child seat of the embodiment can be fixed to the rear carrier of the scooter when the seat is installed in the reverse direction with the occupant facing backward, and at this time, the rear base 22 can be supported and limited by the rear carrier of the scooter.

[0085] In the embodiment, the position of the folding mechanism 1 in the human-carrying state is lower than the upper end surface of the base piece 2. The number of the first folding piece 11 and the second folding piece 12 is two, and the number of the folding locking piece 13 is one, which has a circular cross section. The folding locking piece 13 is slidably arranged on the second folding piece 12, and can slide longitudinally forward and backward on the second folding piece 12. In the embodiment, the direction of forward and backward sliding of the folding locking piece 13 has a certain inclination, and the folding locking piece 13 can be embedded in the clamping groove 14 and kept in position under the action of gravity. When the rear base 22 is forward folded, the second folding piece 12 and the folding locking piece 13 are forward turned together with the rear base 22 around the hinge point.

[0086] In the embodiment, the first folding piece 11 and the front base 21, the second folding piece 12 and the rear base 22, the backrest piece 4, and the side wing piece 5 are respectively connected by two types of parts made of different materials. The pivot 31 of the embodiment is composed of a hinge and part of the front wall blocking piece and part of the front base. The maximum angle of forward turning of the front wall blocking piece 3 is limited by the front base 21.

[0087] The seat provided in the embodiment has two states, one of which is the human-carrying state as shown in Figure 2 and the other of which is the object-carrying state as shown in Figure 3 The specific process of conversion between the two states is as follows:

[0088] In the carrying person use state, the folding locking member 13 is unlocked, the backrest member 4 is pushed to make the second folding member 12, the folding locking member 13, the rear base 22, the backrest member 4, the side wing member 5, and the front wall member 3 together fold forward by swinging, when the backrest member 4 is folded and close to the front wall member 3, the front wall member 3, the front base 21, the rear base 22, the backrest member 4, and the side wing member 5 together form an enclosed structure. After the second folding member 12 and the folding locking member 13 are turned around the hinge point, the folding locking member 13 slides on the second folding member 12 under the action of gravity and is embedded into the clamping groove 14 of the first folding member 11, so that the folding mechanism 1 is locked, at this time, the backrest member 4, the rear base 22, and the side wing member 5 are all limited, and the seat enters the carrying object use state.

[0089] In the carrying object use state, the folding locking member 13 is pulled and the backrest member 4 is folded backward until the rear base 22 is supported by the rear hanger of the two-wheeled vehicle, and then the front wall member 3 is folded backward to be placed on the front base 21, and the seat enters the carrying person use state.

[0090] In the carrying person use state, the seat is provided with a safety belt to prevent the child from being thrown out of the seat in the case of emergency braking. In order to provide a reliable fixing point for the safety belt, the clamping groove 14 on the first folding member 11 can cooperate with the folding locking member 13 to one-way limit the folding mechanism 1 in the carrying person use state, so that the seat cannot be changed from the carrying person use state to the carrying object use state. As shown in Figure 2 The clamping groove 14 can cooperate with the folding locking member 13 to limit the folding mechanism 1 in the carrying person use state, and the number of the clamping groove 14 in the embodiment is two.

[0091] 2. A two-wheeled vehicle multifunctional child seat (first type) second embodiment

[0092] As shown in Figure 4 The embodiment provides a two-wheeled vehicle multifunctional child seat, which comprises a folding mechanism 1, a base member 2, a front wall member 3, a backrest member 4, and a side wing member 5. As shown in Figure 5 The side wing member 5 is fixed on the left and right sides of the backrest member 4. The base member 2 comprises a front base 21 and a rear base 22, the backrest member 4 is connected to the rear end of the rear base 22, the front wall member 3 is connected to the front end of the front base 21 through a rotating shaft 31, and the front base 21 and the rear base 22 are hinged through the folding mechanism 1. The rear base 22, the backrest member 4, and the side wing member 5 can be folded forward together by swinging. As shown in Figure 4 The longitudinal length of the rear base 22 is less than the longitudinal length of the rear hanger of the two-wheeled vehicle, and the front base 21 is fixed on the rear hanger of the two-wheeled vehicle. As shown in Figure 6As shown, the folding mechanism 1 includes a first folding piece 11, a second folding piece 12, and a folding locking piece 13. The folding locking piece 13 is hinged to the second folding piece 12. The first folding piece 11 is provided with a clamping groove 14, which can cooperate with the folding locking piece 13 to one-way limit the folding mechanism 1 in the object-carrying state, so that the seat cannot be converted to the human-carrying state. The existence of the front wall blocking piece 3 limits the maximum angle of the backrest piece 4 forward folding. After the backrest piece 4 is forward folded, the folding locking piece 13 is operated to lock the folding mechanism 1, so that the vehicle-mounted objects can be stored.

[0093] The main difference between the above-mentioned first embodiment of the two-wheeled vehicle multifunctional child seat (first type) and the third embodiment is that: the folding locking piece 13 of the third embodiment is hinged to the second folding piece 12, and the folding locking piece 13 is swung into the clamping groove 14 on the first folding piece 11 to realize the limiting function under the action of gravity; a part of the rotating shaft 31 of the third embodiment is integrally formed with the front wall blocking piece 3, and a part of the rotating shaft 31 of the third embodiment is integrally formed with the front base 21.

[0094] Providing a safety belt for the seat in the human-carrying state can prevent the child from being thrown off the seat during emergency braking. In order to provide a reliable fixing point for the safety belt, the clamping groove 14 of the third embodiment can cooperate with the folding locking piece 13 to one-way limit the folding mechanism 1 in the human-carrying state, so that the seat cannot be converted from the human-carrying state to the object-carrying state.

[0095] 3. A third embodiment of a two-wheeled vehicle multifunctional child seat (first type)

[0096] As shown in the drawings, Figure 7 As shown in the drawings, the third embodiment provides a two-wheeled vehicle multifunctional child seat, which includes a folding mechanism 1, a base piece 2, a front wall blocking piece 3, a backrest piece 4, and a side wing piece 5. As shown in the drawings, Figure 8 As shown in the drawings, the base piece 2 includes a front base 21 and a rear base 22, and the side wing piece 5 is fixed to the left and right sides of the backrest piece 4. The backrest piece 4 is connected to the rear end of the rear base 22, and the front wall blocking piece 3 is connected to the front end of the front base 21 through a rotating shaft 31. The front base 21 and the rear base 22 are hinged through the folding mechanism 1, and the rear base 22, the backrest piece 4, and the side wing piece 5 can be folded forward together in a swinging manner. As shown in the drawings, Figure 13 As shown in the drawings, the longitudinal length of the rear base 22 is less than the longitudinal length of the rear luggage rack of the two-wheeled vehicle, and the front base 21 is fixed to the rear luggage rack of the two-wheeled vehicle. As shown in the drawings, Figure 9As shown, the folding mechanism 1 includes a first folding piece 11, a second folding piece 12, and a folding locking piece 13. The folding locking piece 13 is slidably arranged on the second folding piece 12 and longitudinally slides on the second folding piece 12. The first folding piece 11 is provided with a clamping groove 14 which can cooperate with the folding locking piece 13 to unidirectionally limit the folding mechanism 1 in the object-carrying state, so that the seat cannot be changed to the person-carrying state. The existence of the front wall blocking piece 3 limits the maximum angle of the backrest piece 4 when it is folded forward. After the backrest piece 4 is folded forward, the folding locking piece 13 is operated to limit the folding mechanism 1, so that the vehicle object can be stored.

[0097] The difference between the above-mentioned first embodiment of the two-wheeled vehicle multifunctional child seat (first type) and the present embodiment mainly lies in that the number of the first folding piece 11 and the second folding piece 12 is one; the first folding piece 11 and the rear seat 22 are two parts integrally formed of the same material, and the second folding piece 12 and the front seat 21 are two parts integrally formed of the same material; the cross-sectional shape of the folding locking piece 13 is rectangular; and the folding locking piece 13 can be kept in the clamping groove 14 under the action of friction. The pivot 31 of the present embodiment is a separate component which is connected to the front wall blocking piece 3 and the front seat 21 respectively.

[0098] The seat is provided with a safety belt to prevent the child from being thrown out of the seat in an emergency brake. In order to provide a reliable fixing point for the safety belt, the clamping groove 14 of the present embodiment can cooperate with the folding locking piece 13 to unidirectionally limit the folding mechanism 1 in the person-carrying state, so that the seat cannot be changed from the person-carrying state to the object-carrying state, as shown in Figure 8 .

[0099] 4. A fourth embodiment of a two-wheeled vehicle multifunctional child seat (first type)

[0100] As shown in Figure 10 , the present embodiment provides a two-wheeled vehicle multifunctional child seat which includes a folding mechanism 1, a seat 2, a front wall blocking piece 3, a backrest piece 4, and a side wing piece 5. As shown in Figure 11 , the seat 2 includes a front seat 21 and a rear seat 22. The backrest piece 4 is connected to the rear end of the rear seat 22. The front wall blocking piece 3 is connected to the front end of the front seat 21 through a hinge 32. The side wing piece 5 is fixed to the left and right sides of the backrest piece 4. The front seat 21 and the rear seat 22 are hingedly connected through the folding mechanism 1. The rear seat 22, the backrest piece 4, and the side wing piece 5 can be folded forward together by swinging. Figure 16 As shown in Figure 12As shown, the folding mechanism 1 includes a first folding piece 11, a second folding piece 12, and a folding locking piece 13. The folding locking piece 13 is detachably connected to the second folding piece 12. The first folding piece 11 is provided with a clamping groove 14 which can cooperate with the folding locking piece 13 to unidirectionally limit the folding mechanism 1 in the object-carrying state, so that the seat cannot be converted to the human-carrying state. After the backrest piece 4 is folded forward, the folding locking piece 13 is operated to lock the folding mechanism 1, so that the vehicle articles can be stored.

[0101] Different from the first embodiment of the above-mentioned two-wheeled multi-functional child seat (the first type), the first folding piece 11 and the rear base 22 of the present embodiment are two parts integrally formed of the same material, the second folding piece 12 and the front base 21 are two parts integrally formed of the same material, the folding locking piece 13 is a bolt which is detachably connected to the second folding piece 12, the number of the clamping grooves 14 is one, and the front barrier 3 is connected to the front base 21 through a hinge 32 with a limiting function.

[0102] From the above four embodiments, it can be known that in the human-carrying state and the object-carrying state, the folding locking piece 13 can be designed to be obliquely slidably arranged on the second folding piece 12, the gravity is used to make the folding locking piece 13 slide and enter the clamping groove 14, and the position of the folding locking piece 13 is kept to limit the folding mechanism 1; the friction between the folding locking piece 13 and the second folding piece 12 can also be used to keep the position of the folding locking piece 13 to limit the folding mechanism 1; the folding locking piece 13 can also be designed to be hinged to the second folding piece 12, the center of mass of the folding locking piece 13 is lower than the hinge point, and under the action of gravity, the folding locking piece 13 enters the clamping groove 14, the position of the folding locking piece 13 is kept, and the folding mechanism 1 is limited; the folding locking piece 13 in the form of a bolt can also be designed to be screwed into the clamping groove 14 on the first folding piece 11, the position of the folding locking piece 13 is kept by using the friction, and the folding mechanism 1 is limited.

[0103] 5. A first embodiment of a two-wheeled multi-functional child seat (the second type)

[0104] As shown in the drawings, Figure 13 The present embodiment provides a non-motor vehicle multi-functional child seat, which includes a folding mechanism 1, a base piece 2, a front barrier 3, a backrest piece 4, and a side wing piece 5.

[0105] As shown in the drawings, Figure 14As shown, the base component 2 includes a front base 21 and a rear base 22. The backrest component 4 is connected to the rear end of the rear base 22, and the side wings 5 ​​are connected to the left and right sides of the backrest component 4. The front baffle component 3 is connected to the front base 21 via a pivot 31. The front base 21 and the rear base 22 are hinged by a folding mechanism 1, and the rear base 22, the backrest component 4, and the side wings 5 ​​can all fold forward together by swinging.

[0106] like Figure 15 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 has a slot 14. The slot 14 can cooperate with the folding locking member 13 to unidirectionally limit the folding mechanism 1 in the passenger-carrying state, limiting the maximum unfolding angle of the backrest member 4, so that the rear base 22 and the backrest member 4 can support a child's seating. The slot 14 can also cooperate with the folding locking member 13 to unidirectionally limit the folding mechanism 1 in the cargo-carrying state, preventing the seat from changing to the passenger-carrying state. In the cargo-carrying state, the front barrier 3 limits the maximum forward folding angle of the backrest member 4, and the folding mechanism 1 limits the rearward folding of the backrest member 4.

[0107] In this embodiment, the first folding member 1 and the front base member 21, the second folding member 12 and the rear base 22, the backrest member 4 and the side wing member 5 are all two types of parts made of different materials and are connected to each other. In this embodiment, there are two of each of the first folding member 11 and the second folding member 12, and the folding locking member 13 slides longitudinally back and forth on the second folding member 12. The direction of its sliding is somewhat inclined. The pivot 31 in this embodiment is composed of a hinge, a part of the front baffle member, and a part of the front base. The maximum forward rotation angle of the front baffle member 3 is limited by the front base 21.

[0108] The seat provided in this application embodiment has two usage states: one is a passenger-carrying usage state, such as... Figure 14 As shown; another is the cargo-carrying usage state, such as Figure 15As shown. The specific process of the two state transitions is as follows: Pulling the folding locking piece 13 unlocks the folding mechanism 1, pushing the backrest piece 4 causes the rear base 22, the second folding piece 12, the folding locking piece 13, the backrest piece 4, and the side wing piece 5 to fold forward together by swinging. After folding, the front enclosure piece 3, the front base 21, the rear base 22, the backrest piece 4, and the side wing piece 5 together form an enclosing structure. Inserting the folding locking piece 13 into the slot 14 locks the folding mechanism 1, preventing the backrest piece 4, the rear base 22, and the side wing piece 5 from folding backward. At this time, the seat enters the cargo-carrying state. Pulling the folding locking piece 13 unlocks the folding mechanism 1, then flipping the backrest piece 4 backward and inserting the folding locking piece 13 into the slot 14, at which point the rear base 22 is limited by the folding mechanism 1, and the seat enters the passenger-carrying state.

[0109] To address the issue of increased gap between the front base 21 and the rear base 22 when the seat transitions from passenger use to cargo use, the hinge points of the first folding member 11 and the second folding member 12 in this embodiment are designed to be lower than the upper surface of the base member 2 when in passenger use.

[0110] like Figure 14 As shown, in order to provide a fixed point for the seat belt and improve the safety of children riding in passenger mode, the folding locking member 13 of this embodiment can cooperate with the slot 14 to limit the folding mechanism 1 in both directions in passenger mode.

[0111] 6. A second embodiment of a multi-functional child seat for a two-wheeled vehicle (Type II)

[0112] like Figure 16 As shown, this embodiment provides a multi-functional child seat for non-motorized vehicles, including: a folding mechanism 1, a base 2, a front bumper 3, a backrest 4, and side wings 5; as Figure 17 As shown, the base component 2 includes a front base 21 and a rear base 22. The backrest component 4 is connected to the rear end of the rear base 22. The front baffle component 3 is connected to the front base 21 via a pivot 31. Side wings 5 ​​are connected to the left and right sides of the backrest component 4. The front base 21 and the rear base 22 are hinged together by a folding mechanism 1. The rear base 22, the backrest component 4, and the side wings 5 ​​can all fold forward together by swinging. Figure 18As 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 hinged to the second folding member 12. A slot 14 is provided on the first folding member 11. The slot 14 can cooperate with the folding locking member 13 to bidirectionally limit the folding mechanism 1 in the passenger-carrying state, restricting the unfolding angle of the rear base 22 so that the rear base 22 and the backrest 4 can support the child. The slot 14 can also cooperate with the folding locking member 13 to unidirectionally limit the folding mechanism 1 in the cargo-carrying state, preventing the seat from changing to the passenger-carrying state. In the cargo-carrying state, the front baffle 3 limits the maximum forward folding angle of the backrest 4, and the folding mechanism 1 restricts the rearward folding of the backrest 4.

[0113] The main difference between this embodiment and the first embodiment of the above-mentioned multi-functional child seat for two-wheeled vehicles (type 2) is that: the backrest 4 and the side wing 5 of this embodiment are two parts integrally formed from the same material; the folding locking member 13 is hinged to the second folding member 12; a part of the pivot 13 is integrally formed with the front baffle 3, and a part of the pivot 13 is integrally formed with the front base 21.

[0114] To address the issue of increased gap between the front base 21 and the rear base 22 when the seat transitions from passenger use to cargo use, the hinge points of the first folding member 11 and the second folding member 12 in this embodiment are designed to be lower than the upper surface of the base member 2 when in passenger use.

[0115] In order to provide a fixed point for the seat belt and improve the safety of children riding in the seat when it is in use with passengers, the folding locking member 13 in this embodiment can cooperate with the slot 14 to limit the folding mechanism 1 in both directions when it is in use with passengers.

[0116] 7. A third embodiment of a multi-functional child seat for a two-wheeled vehicle (Type II).

[0117] like Figure 19 As shown, this embodiment provides a multi-functional child seat for non-motorized vehicles, including: a folding mechanism 1, a base 2, a front bumper 3, a backrest 4, and side wings 5; as Figure 20 As shown, the base component 2 includes a front base 21 and a rear base 22. The backrest component 4 is connected to the rear end of the rear base 22. The front baffle component 3 is connected to the front base 21 via hinges 32. Side wings 5 ​​are connected to the left and right sides of the backrest component 4. The front base 21 and the rear base 22 are hinged together by a folding mechanism 1. The rear base 22, the backrest component 4, and the side wings 5 ​​can all fold forward together by swinging. Figure 21As shown, the folding mechanism 1 includes a first folding piece 11, a second folding piece 12, and a folding locking piece 13 which is detachably connected to the second folding piece 12. A clamping groove 14 is formed on the first folding piece 11. The clamping groove 14 can cooperate with the folding locking piece 13 to limit the folding mechanism 1 in both directions in the human-carrying state, thereby limiting the unfolding angle of the rear base 22 and enabling the rear base 22 and the backrest piece 4 to support a child. The clamping groove 14 can also cooperate with the folding locking piece 13 to limit the folding mechanism 1 in one direction in the object-carrying state, thereby preventing the seat from being converted to the human-carrying state. In the object-carrying state, the front barrier piece 3 limits the maximum angle of the backrest piece 4 in forward folding, and the folding mechanism 1 limits the backrest piece 4 in backward folding.

[0118] The main difference between the above-mentioned first embodiment of the two-wheeled multi-functional child seat (second type) and the present embodiment is that the first folding piece 11 and the rear base 22 are two parts integrally formed of the same material, and the second folding piece 12 and the front base 21 are two parts integrally formed of the same material. The folding locking piece 13 is a bolt which is detachably connected to the second folding piece 12. In the present embodiment, the hinge point of the first folding piece 11 and the second folding piece 12 is higher than the upper end surface of the base piece 2. The front barrier piece 3 of the present embodiment is connected to the front base 21 through a hinge 32 with a limiting function.

[0119] The second two-wheeled multi-functional child seat does not rely on the rear luggage rack of the two-wheeled vehicle, thereby eliminating the influence of environmental features and removing the size limitation of the rear base.

[0120] 8. A first embodiment of a two-wheeled multi-functional child seat (third type)

[0121] As shown, the present embodiment provides a non-motorized multi-functional child seat, which includes a folding mechanism 1, a base piece 2, a front barrier piece 3, a backrest piece 4, and a side wing piece 5. Figure 22 As shown, the base piece 2 includes a front base 21 and a rear base 22 which are hingedly connected through the folding mechanism 1. The front barrier piece 3 is connected to the front base 21 through a pivot 31, and the backrest piece 4 is connected to the rear end of the rear base 22. The front barrier piece 3 limits the maximum angle of the backrest piece 4 in forward folding around the hinge point. When the backrest piece 4 is folded forward to approach the front barrier piece 3, the front barrier piece 3, the front base 21, the rear base 22, and the backrest piece 4 form a closed structure together. The side wing piece 5 is connected to the left and right sides of the backrest piece 4, and the side wing piece 5 is used to enclose the closed structure formed by the front barrier piece 3, the front base 21, the rear base 22, and the backrest piece 4 from the side.

[0122] Figure 23 ​​

[0123] As shown in Figure 24 The folding mechanism 1 includes a first folding piece 11, a second folding piece 12, and a folding lock piece 13. The first folding piece 11 is connected with the front base 21, and the second folding piece 12 is connected with the rear base 22. The folding lock piece 13 is hinged to the second folding piece 12. A clamping groove 14 is formed on the first folding piece 11, and the folding lock piece 13 can be matched with the clamping groove 14 to limit the folding mechanism 1 in the one-way direction in the load-carrying state, so that the seat cannot be converted to the human-carrying state. The first folding piece 11 is provided with a positioning protrusion 15, and the second folding piece 12 is provided with a positioning clamping groove 16. The positioning protrusion 15 and the positioning clamping groove 16 limit the maximum unfolding angle of the folding mechanism 1 in the human-carrying state. It should be noted that the positioning protrusion 15 and the positioning clamping groove 16 limit the maximum unfolding angle of the rear base 22 in the human-carrying state, so as to ensure that the seat is seatable regardless of how it is installed on a non-motor vehicle, and the influence of environmental characteristics is eliminated.

[0124] The folding seat forms an enclosed space by part of the structure and limits the folding mechanism 1 by the folding lock piece 13, so that the seat enters the load-carrying state. In the load-carrying state, the front barrier 3 limits the forward folding of the backrest 4, and the folding mechanism 1 limits the rearward folding of the backrest 4, so as to realize the storage of articles. In the human-carrying state, the positioning protrusion 15 and the positioning clamping groove 16 limit the folding mechanism 1 and limit the maximum angle of the rearward folding of the rear base 22, so as to realize the seating of children.

[0125] In this embodiment, in order to solve the problem that the gap between the front base 21 and the rear base 22 becomes larger after the seat is converted from the human-carrying state to the load-carrying state. The hinge points of the first folding piece 11 and the second folding piece 12 in this embodiment are designed to be lower than the upper end surface of the base 2, so that after the backrest 4 and the rear base 22 are forward folded, the gap between the front base 21 and the rear base 22 is reduced. Smaller gap is conducive to the storage of articles carried by the vehicle.

[0126] In the human-carrying state, the forward folding of the folding mechanism 1 is not limited, which will cause the safety belt to lack a fixed point. In order to improve the safety of the seat in the human-carrying state, the folding lock piece 13 in this embodiment is designed to be matched with the clamping groove 14 to limit the forward folding of the backrest 4 in the human-carrying state.
