Description

Technical Field

[0001] The utility model 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

[0002] 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

[0003] In order to solve the problem that it is difficult to balance the installation of 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 utility model 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.

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

[0005] 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. The one-way limiting folding mechanism in the state of carrying goods makes it impossible for the multifunctional child seat of the two-wheeled vehicle to 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, and the self-locking of the folding mechanism can also be achieved. The utility model 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.

[0006] 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 multifunctional child seat of the two-wheeled vehicle 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 a multifunctional child seat (first type) of a two-wheeled vehicle 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 specified in the "Safety Requirements and Test Methods for Child Seats for Imported and Exported Bicycles" (GB / T 23160-2008), among which: the length of the rear seat of the A15 type is between 160mm and 220mm, and the length of the rear seat of the A22 type 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.

[0007] The front enclosure member is fixed to the front base or detachably connected to the front base. The existence of the front enclosure member limits the maximum angle of the backrest member to be folded forward. The end surface of the front enclosure member can be a plane or a curved surface. The shape of the end surface can enclose the enclosed structure formed by the backrest member, the side wing member and the base member. The size of the enclosure gap is not limited as long as the helmet does not fall off.

[0008] 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 utility model 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.

[0009] 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.

[0010] The folding part structure forms an enclosed space, and the folding locking part limits the folding mechanism, so that a two-wheeled vehicle multifunctional child seat (first type) can have the function of carrying objects. In the state of carrying objects, the front enclosure limits the forward flipping of the backrest part, and the flip locking part limits the backward flipping of the backrest part, thereby realizing the reliable storage of objects. In the state of carrying people, the flip locking part is unlocked, and the backrest part is flipped backward until it is limited by the rear clothes hanger of the two-wheeled vehicle, and the two-wheeled vehicle multifunctional child seat enters the state of carrying people.

[0011] Furthermore, in order to solve the problem that the backrest part is not limited in the forward flipping state when the passenger is in use, 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 passenger is in use, thereby limiting the forward flipping of the backrest part, so that the two-wheeled 1 multifunctional child seat cannot be transformed from the passenger use state to the cargo use state. The backrest part that is limited in both directions in the passenger state 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.

[0012] In order to eliminate the limitation of the environmental characteristics on the size of the rear base, according to one aspect of the utility model, a two-wheeled vehicle multifunctional child seat (type) is provided, comprising: a folding mechanism, a base member, a front enclosure member, a backrest member and side wing members.

[0013] 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 multifunctional child seat of the two-wheeled vehicle 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 utility model 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 locking member limits and supports the backrest member and the rear base, thereby ensuring that no matter how it is installed on the two-wheeled vehicle, the two-wheeled vehicle multifunctional child seat (second type) is always rideable, eliminating the restriction of the rear hanger of the two-wheeled vehicle on the length of the rear base.

[0014] 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.

[0015] The front enclosure is fixed to the front base or detachably connected to the front base, and the existence of the front enclosure limits the maximum angle of the backrest member to be folded forward. The end surface of the front enclosure can be a plane or a curved surface, and the shape of the end surface can enclose the enclosed structure formed by the backrest member, the side wing member and the base member from the side, and the size of the enclosed gap is not limited as long as the helmet does not fall off.

[0016] The backrest is connected to the rear base. The maximum angle of the backrest forward flipping 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. When the utility model is used outdoors, it will be exposed to rain and snow. 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.

[0017] 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.

[0018] The folding part of the structure of the multifunctional child seat for two-wheeled vehicles forms an enclosed space and uses the folding locking part to limit the folding mechanism, so that a multifunctional child seat for two-wheeled vehicles (second type) can have the function of carrying objects. In the state of carrying objects, the front enclosure limits the forward flipping of the backrest, and the folding locking part cooperates with the card slot to limit the backward flipping of the backrest, so as to achieve the storage of objects. In the state of carrying people, the folding locking part and the card slot limit the backward flipping of the backrest, so as to achieve the riding of children.

[0019] Furthermore, the position of the hinge center of the first folding member and the second folding member in the state of passenger use will affect the size of the gap between the front base and the rear base in the state of cargo use. When the position of the hinge center is higher than the upper end surface of the base member, pushing the backrest member to fold forward will cause the front base and the rear base to move away from each other and the gap to become larger, which is not conducive to the storage of items on the vehicle. For this reason, the above technical solution is further improved: the position of the hinge center of the first folding member and the second folding member is designed so that it is not higher than the upper end surface of the base member in the state of passenger use. 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 hinge center of 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 are close to each other; the parts that are lower than the hinge point are away from each other. The position of the hinge center of the first folding member and the second folding member is designed to be no higher than the upper end surface of the base member, which can reduce the gap between the front base and the rear base in the loading state, which is conducive to storing small items.

[0020] Furthermore, when the second folding piece is connected to the front base, the folding locking piece is located below the front base, and it is not convenient to operate the folding locking piece. To this end, the above technical solution is further improved: the first folding piece is connected to the front base, and the second folding piece is connected to the rear base. At this time, the folding locking piece and the second folding piece are flipped together with the rear base, and the position of the folding locking piece is lifted up in the state of loading and using, which is convenient for operating the folding locking piece. The first folding piece and the front base can be two parts integrally formed of the same material, or they can be a combination of two parts of the same material or different materials. The second folding piece and the rear base can be two parts integrally formed of the same material, or they can be a combination of two parts of the same material or different materials.

[0021] Optionally, the backrest is not limited in position when the seat is used with passengers, so that the safety belt lacks a fixed point, and the safety of children riding on it needs to be improved. To this end, the technical solution provided by the embodiment of the utility model is: designing a card slot that can cooperate with the folding locking piece, so that the folding locking piece and the card slot cooperate with each other, and a two-way limited folding mechanism is used in the state of carrying passengers. The backrest that is limited in both directions in the state of carrying passengers can fix the safety belt. According to the different shapes of the folding locking piece, the number of the card slots is not limited to one or two.

[0022] According to one aspect of the utility model, a multifunctional child seat for a two-wheeled vehicle (third type) is provided, comprising: a folding mechanism, a base member, a front enclosure member, a backrest member and side wing members.

[0023] 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 prevents the multifunctional child seat for a two-wheeled vehicle from being 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 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 is used to achieve self-locking of the folding mechanism; the folding locking member 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 utility model also provides a folding safety device for a multifunctional child seat of 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.

[0024] 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.

[0025] The front enclosure is fixed to the front base or detachably connected to the front base, and the existence of the front enclosure limits the maximum angle of the backrest member to be folded forward. The end surface of the front enclosure can be a plane or a curved surface, and the shape of the end surface can enclose the enclosed structure formed by the backrest member, the side wing member and the base member from the side, and the size of the enclosed gap is not limited as long as the helmet does not fall off.

[0026] The backrest is connected to the rear base. The maximum angle of the backrest flipping 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 utility model is 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 prevent the helmet from falling off.

[0027] 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.

[0028] The folding part of the multifunctional child seat for two-wheeled vehicles forms an enclosed space and is limited by the folding locking part, so that a multifunctional child seat for two-wheeled vehicles (type 3) can have the function of carrying objects. In the state of carrying objects, the front enclosure limits the forward folding of the backrest, and the folding locking part and the card slot limit the backward folding of the backrest, thereby realizing the storage of objects. In the state of carrying people, the positioning protrusion and the positioning card slot limit the folding mechanism, limit the maximum angle of the backward folding of the backrest, thereby realizing the riding of children.

[0029] Furthermore, the position of the hinge center of the first folding member and the second folding member in the state of passenger use will affect the size of the gap between the front base and the rear base in the state of cargo use. When the position of the hinge center is higher than the upper end surface of the base member, pushing the backrest member to fold forward will cause the front base and the rear base to move away from each other and the gap to become larger, which is not conducive to the storage of items on the vehicle. For this reason, the above technical solution is further improved: the position of the hinge center of the first folding member and the second folding member is designed so that it is not higher than the upper end surface of the base member in the state of passenger use. 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 hinge center of 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 are close to each other; the parts that are lower than the hinge point are away from each other. The position of the hinge center of the first folding member and the second folding member is designed to be no higher than the upper end surface of the base member, which can reduce the gap between the front base and the rear base in the loading state, which is conducive to storing small items.

[0030] Furthermore, when the second folding piece is connected to the front base, the folding locking piece is located below the front base, and it is not convenient to operate the folding locking piece. To this end, the above technical solution is further improved: the first folding piece is connected to the front base, and the second folding piece is connected to the rear base. At this time, the folding locking piece and the second folding piece are flipped together with the rear base, and the position of the folding locking piece is lifted up in the state of loading and using, which is convenient for operating the folding locking piece. The first folding piece and the front base can be two parts integrally formed of the same material, or they can be a combination of two parts of the same material or different materials. The second folding piece and the rear base can be two parts integrally formed of the same material, or they can be a combination of two parts of the same material or different materials.

[0031] Optionally, the backrest is not limited in position when the seat is used with passengers, so that the safety belt lacks a fixed point, and the safety of children riding on it needs to be improved. To this end, the technical solution provided by the embodiment of the utility model is: designing a card slot that can cooperate with the folding locking piece, so that the folding locking piece and the card slot cooperate with each other, and a two-way limited folding mechanism is used in the state of carrying passengers. The backrest that is limited in both directions in the state of carrying passengers can fix the safety belt. According to the different shapes of the folding locking piece, the number of the card slots is not limited to one or two.

[0032] Optionally, a lifting structure is introduced so that the backrest can be adjusted in height to accommodate children of different heights. Specifically, in some embodiments, it also includes: a rear vertical fixing frame, a rear vertical motion frame, and a lifting locking member.

[0033] The rear vertical fixing frame is provided with a first limiting hole, and the rear vertical fixing frame can be directly connected to the rear base or indirectly connected to the rear base through other components. For example, the rear vertical fixing frame is directly connected to the first folding member or the second folding member, thereby indirectly connecting to the rear base; the rear vertical fixing frame and the rear base can be two parts integrally formed of the same material.

[0034] The rear vertical motion frame is slidably mounted on the rear vertical fixed frame, and a second limiting hole is provided on the rear vertical motion frame. The backrest is fixed to the rear vertical motion frame. The rear vertical motion frame and the backrest 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.

[0035] The lifting locking member includes a lifting locking member body, a locking pin, and an elastic member. The lifting locking member body is slidably mounted on the rear vertical fixing frame, and the backrest member is fixed to the lifting locking member body. The lifting locking member body 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. The locking pin is slidably mounted on the lifting locking member body, and under the action of the elastic member, the locking pin is simultaneously embedded in the first limit hole and the second limit hole to realize the lifting locking function. The backrest member that can be raised and lowered to adjust the height provides more adequate back support for the child, and the side wing member is raised and lowered together with the backrest member. When the position of the backrest member is sufficient to support the child's head, the side wing member can also protect the child's head from the side.

[0036] When storing items for a long time in a state of carrying goods, the problem of theft prevention needs to be considered; when the folding locking member is used to carry people, the limit folding mechanism has the problem of accidental unlocking. To this end, according to another aspect of the utility model, 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 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 11 equipped with the folding safety device.

[0037] The longitudinal connecting piece is fixed to the folding mechanism and is used to install the rear pull rod. The longitudinal connecting piece can be a hollow structure or a solid structure, and its extension path can be a straight line or a curve.

[0038] The rear pull rod is slidably arranged on the 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.

[0039] 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 can be used to limit the rear pull rod or the front and rear connecting rods to indirectly limit the position of the folding locking member.

[0040] The introduction of the transverse connector provides a wider range of points for the lock body. When the number of longitudinal connectors is more than one, the transverse connector can simultaneously connect multiple longitudinal connectors to reinforce the seat.

[0041] When the folding locking member slides longitudinally, the rear pull rod is driven by the front and rear connecting rods to slide forward and backward. When the folding locking member 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 member slides transversely, the rear pull rod is driven by the front and rear connecting rods to slide horizontally left and right. When the folding locking member is screwed into the first folding member, the rear connecting rod is sleeved on the folding locking member. 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 horizontally.

[0042] 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.

[0080] 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".

[0081] 1. The first embodiment of the multifunctional child seat for a two-wheeled vehicle

[0082] 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 front enclosure member 3, a backrest member 4 and side wing members 5.

[0083] like Figure 2 As 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 4, and the side wing member 5 can be folded forward together by swinging. There are two side wing members 5, which are respectively connected to the left and right sides of the backrest member 4, and the backrest member 4 is connected to the rear end of the rear base member 22. The front enclosure member 3 is detachably connected to the front base 21.

[0084] 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 goods, 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 member 3 limits the maximum angle of the backrest member 4 to be folded forward. When the seat is used for carrying goods, the folding locking member 13 can be operated to enter the slot 14 to store the items on the vehicle.

[0085] In this embodiment, the seat is 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 utility model 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.

[0086] In this embodiment, the position of the folding mechanism 1 is lower than the upper end surface of the base member 2, the number of the first folding member 11 and the second folding member 12 are both two, 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 forward and backward on the second folding member 12. The direction of the folding locking member 13 sliding forward and backward is designed to have a certain inclination, and the folding locking member 13 can maintain its position under the action of gravity and always be embedded in the card slot 14 of the first folding member 11. 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.

[0087] In this embodiment, the first folding member 11 and the front base 21 are two parts of different materials and are rigidly connected to each other. The second folding member 12 and the rear base 22 are two parts of different materials and are rigidly connected to each other. The backrest member 4 and the side wing member 5 are two parts of different materials, and the side wing member 5 is fixed to the backrest member 4. The front enclosure member 3 and the front base 21 are two parts of different materials, and the front enclosure member 3 is pluggable and connected to the front base 21.

[0088] 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:

[0089] In the passenger-carrying state, the folding locking member 13 is unlocked, and 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, and the side wing member 5 fold forward together by swinging. When the backrest member 4 is folded and close to the front enclosure member 3, the front enclosure member 3, the front base 21, the rear base 22, the backrest member 4, and the side wing member 5 together form an enclosure structure. 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 4, the rear base 22, and the side wing member 5 are all limited, and the seat enters the cargo-carrying state.

[0090] In the state of using for carrying goods, the folding locking member 13 is pulled, and the backrest member 4 is folded backward, so that the rear base 22 is supported by the rear clothes hanger of the two-wheeled vehicle, and the seat enters the state of using for carrying people.

[0091] Equipping the seat with a safety belt when the seat is used with people can prevent children from being thrown off the seat in the event of an emergency brake. In order to provide a reliable fixing point for the safety belt, the card slot 14 on the first folding member 11 of this embodiment can cooperate with the folding locking member 13 to limit the folding mechanism 1 in one direction when the seat is used with people, so that the seat cannot be changed from the state of using people to the state of using goods. Figure 2 As shown, the card slot 14 can cooperate with the folding locking member 13 when a passenger is in use, and the number of the card slots 14 of the position-limiting folding mechanism 1 in this embodiment is two.

[0092] 2. A two-wheeled vehicle multifunctional child seat (first type) second embodiment

[0093] 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 front enclosure member 3, a backrest member 4 and side wing members 5.

[0094] like Figure 5 As shown, the side wing members 5 are fixed to the left and right sides of the backrest member 4. The base member 2 includes 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 enclosure member 3 is fixed to the front end of the front base 21. The front base 21 and the rear base 22 are hinged by a folding mechanism 1. The rear base 22, the backrest member 4, and the side wing members 5 can be folded forward together by swinging. Figure 4 As shown, the longitudinal length of the rear base 22 is smaller than the longitudinal length of the rear clothes hanger of the two-wheeled vehicle, and the front base 21 is fixed to the rear clothes hanger of the two-wheeled vehicle.

[0095] like Figure 6 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 arranged on the second folding member 12. A slot 14 is arranged 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 existence of the front enclosure member 3 limits the maximum angle of the backrest member 4 to be folded forward. After the backrest member 4 is folded forward, the folding locking member 13 can be operated to limit the folding mechanism 1 so that the articles accompanying the vehicle can be stored.

[0096] The difference between this embodiment and the first embodiment of the above-mentioned multifunctional child seat for two-wheeled vehicles (first type) is that the folding locking member 13 is slidably mounted on the second folding member 12 and moves in a horizontal sliding direction from left to right; the child seat of the embodiment of the utility model is installed in reverse, and the child faces the rear of the two-wheeled vehicle. The folding locking member 13 is slid horizontally to leave the slot of the first folding member 11, and the limit on the folding mechanism 1 can be released. The backrest member 4, the side wing member 5, the rear base 22, and the first folding member 11 are pushed forward to fold together to form an enclosure structure, and then the folding locking member 13 and the slot 14 are used to lock the folding mechanism 1, and the seat enters the state of loading.

[0097] Equipping the seat with a safety belt when the seat is used with people can prevent children from being thrown off the seat in the event of an emergency brake. In order to provide a reliable fixing point for the safety belt, the card slot 14 on the first folding member 11 of this embodiment can cooperate with the folding locking member 13 to limit the folding mechanism 1 in one direction when the seat is used with people, so that the seat cannot be changed from the state of using people to the state of using goods. Figure 5 As shown, the card slot 14 can cooperate with the folding locking member 13 when the vehicle is in use with passengers, so as to limit the folding mechanism 1. In this embodiment, there are two card slots 14.

[0098] 3. A third embodiment of a multifunctional child seat for a two-wheeled vehicle (first type)

[0099] like Figure 7 As shown, this embodiment provides a multifunctional child seat for a two-wheeled vehicle, comprising: a folding mechanism 1, a base member 2, a front enclosure member 3, a backrest member 4 and side wing members 5.

[0100] like Figure 8 As shown, the side wing members 5 are fixed to the left and right sides of the backrest member 4. The base member 2 includes 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 enclosure member 3 is fixed to the front end of the front base 21. The front base 21 and the rear base 22 are hinged by a folding mechanism 1. The rear base 22, the backrest member 4, and the side wing members 5 can be folded forward together by swinging. Figure 7 As shown, the longitudinal length of the rear base 22 is smaller than the longitudinal length of the rear clothes hanger of the two-wheeled vehicle, and the front base 21 is fixed to the rear clothes hanger of the two-wheeled vehicle.

[0101] like Fig. 9 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 hinged 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. In the state of loading, the folding mechanism 1 is limited in one direction, so that the seat cannot be transformed into the state of loading. The existence of the front enclosure member 3 limits the maximum angle of the backrest member 4 to be folded forward. After the backrest member 4 is folded forward, the folding mechanism 1 can be locked by the folding locking member 13 to realize the storage of the articles on the vehicle.

[0102] The difference from the first embodiment of the above-mentioned two-wheeled vehicle multifunctional child seat (first type) 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 enclosure 3 of this embodiment is fixed to the front base 21.

[0103] When the seat is used with passengers, equipping it with a seat belt can prevent young children from being thrown out of the seat in the event of an emergency brake. Figure 8As shown, in order to provide a reliable fixing point for the safety belt, the card slot 14 on the first folding member 11 of this embodiment can cooperate with the folding locking member 13 to unidirectionally limit the folding mechanism 1 in the passenger use state, so that the seat cannot be transformed from the passenger use state to the cargo use state.

[0104] 4. A multifunctional child seat for a two-wheeled vehicle (first type) Fourth embodiment

[0105] like Fig.10 As shown, this embodiment provides a multifunctional child seat for a two-wheeled vehicle, comprising: a folding mechanism 1, a base member 2, a front enclosure member 3, a backrest member 4 and side wing members 5.

The front base 21 and the rear base 22 are hinged by a folding mechanism 1, and the rear base 22, the backrest member 4, and the side wing members 5 can be folded forward together by swinging. Fig.10 As shown, the longitudinal length of the rear base 22 is smaller than the longitudinal length of the rear clothes hanger of the two-wheeled vehicle, and the front base 21 is fixed to the rear clothes hanger of the two-wheeled vehicle.

[0107] like Fig.12 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 disposed on the second folding member 12, and slides longitudinally forward and backward on the second folding member 12. A card slot 14 is disposed on the first folding member 11, and the card slot 14 can cooperate with the folding locking member 13 to limit the folding mechanism 1 in a one-way position in the cargo-carrying state, so that the seat cannot be transformed into a passenger-carrying state. The presence of the front enclosure member 3 limits the maximum angle of the backrest member 4 to fold forward. After the backrest member 4 is folded forward, the folding locking member 13 can be operated to limit the folding mechanism 1 so that the accompanying items can be stored.

[0108] The difference between this embodiment and the first embodiment of the first two-wheeled vehicle multifunctional child seat mentioned above lies in that: the front enclosure 3 and the front base 21 of this embodiment are two parts integrally formed of the same material; the front enclosure 3 is provided with holes for children to hold; the front base 21 is provided with a leg avoidance gap for children to place their legs; the number of the first folding member 11 and the second folding member 12 are both one; the first folding member 11 is connected to the rear base 22, and the second folding member 12 is connected to the front base 21; the first folding member 11 and the rear base 22 are two parts integrally formed of the same material, and the second folding member 12 and the front base 21 are two parts integrally formed of the same material; the transverse cross-section of the folding locking member 13 is rectangular; the folding locking member 13 can be retained in the slot 14 under the action of friction.

[0109] In the state of carrying people, equipping the seat with a safety belt can prevent children from being thrown off the seat in the event of an emergency brake. In order to provide a reliable fixing point for the safety belt, the card slot 14 on the first folding member 11 of this embodiment can cooperate with the folding locking member 13 to limit the folding mechanism 1 in one direction in the state of carrying people, so that the seat cannot be changed from the state of carrying people to the state of carrying goods. Fig.11 shown.

[0110] 5. A multifunctional child seat for a two-wheeled vehicle (first type) Fifth embodiment

[0111] like Fig.13 As shown, this embodiment provides a multifunctional child seat for a two-wheeled vehicle, comprising: a folding mechanism 1, a base member 2, a front enclosure member 3, a backrest member 4 and side wing members 5.

[0112] like Fig.14 As shown, the base member 2 includes 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 enclosure member 3 is fixed to the front end of the front base 21, and the side wing members 5 are fixed to the left and right sides of the backrest member 4. The front base 21 and the rear base 22 are hinged by a folding mechanism 1, and the rear base 22, the backrest member 4, and the side wing members 5 can be folded forward together by swinging. Fig.13 As shown, the longitudinal length of the rear base 22 is smaller than the longitudinal length of the rear clothes hanger of the two-wheeled vehicle, and the front base 21 is connected to the rear clothes hanger of the two-wheeled vehicle.

[0113] like Fig.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 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 4 is folded forward, the folding locking member 13 is operated to lock the folding mechanism 1 so that the articles carried by the vehicle can be stored.

[0114] The difference from the first embodiment of the above-mentioned two-wheeled vehicle multifunctional child seat (first type) is that: the front enclosure 3 and the front base 21 of this embodiment are two parts integrally formed of the same material, 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.

[0115] It can be known from the above five embodiments that, in the passenger use state and the cargo use state, the folding locking member 13 can be designed to be tilted and slidably arranged on the second folding member 12, and gravity can be used to make the folding locking member 13 slide and enter the slot 14 to achieve the limitation of the folding mechanism 1; the friction between the folding locking member 13 and the second folding member 12 can also be used to achieve the limitation of the folding mechanism 1; the folding locking member 13 can also be designed to be hinged to the second folding member 12, and when the center of mass of the folding locking member 13 is lower than its hinge point, it enters the slot 14 under the action of gravity, which can also achieve the limitation of the folding mechanism 1; the folding locking member 13 can also be designed in a bolt style to be screwed into the first folding member 11 to achieve the limitation of the folding mechanism 1.

[0116] 6. A two-wheeled vehicle multifunctional child seat (second type) first embodiment

[0117] like Fig.16 As shown, this embodiment provides a multifunctional child seat for a two-wheeled vehicle, comprising: a folding mechanism 1, a base member 2, a front enclosure member 3, a backrest member 4, and side wing members 5.

[0118] like Fig.17 As shown, the base member 2 includes 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 side wing members 5 are connected to the left and right sides of the backrest member 4, and the front enclosure member 3 is detachably connected to the front base 21. The front base 21 and the rear base 22 are hinged by a folding mechanism 1, and the rear base 22, the backrest member 4, and the side wing members 5 can be folded forward together by swinging.

[0119] like Fig.18 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, and a slot 14 is provided on the first folding member 11. The slot 14 can cooperate with the folding locking member 13. When the seat is used for carrying people, the one-way limiting folding mechanism 1 limits the unfolding angle of the backrest member 4, so that the rear base 22 and the backrest member 4 can support the children sitting on the seat. The slot 14 can also cooperate with the folding locking member 13. When the seat is used for carrying objects, the one-way limiting folding mechanism 1 prevents the seat from being transformed into the state of carrying people. When the seat is used for carrying objects, the front enclosure member 3 limits the maximum angle of the backrest member 4 to be folded forward, and the folding mechanism 1 limits the backward folding of the backrest member 4.

[0120] In this embodiment, the first folding member 11 and the front base member 21 are two types of parts made of different materials and connected to each other, and the second folding member 12 and the rear base 22 are two types of parts made of different materials and connected to each other. The backrest member 4 and the side wing member 5 are two types of parts made of different materials and connected to each other. In this embodiment, the first folding member 11 and the second folding member 12 are both two in number, and the folding locking member 13 is slidably disposed on the second folding member 12 and slides longitudinally forward and backward on the second folding member 12. The sliding direction of the folding locking member 13 is tilted to a certain extent, so that the folding locking member 13 is embedded in the card slot 14 under the action of gravity. When the rear base 22 is folded forward, the second folding member 12 and the folding locking member 13 are folded forward together around the hinge point.

[0121] The seat provided in the embodiment of the utility model has two use states: one is a passenger use state, such as Fig.17 As shown; the other is the cargo use status, such as Fig.18 As shown. The specific process of the two state conversion is: pull the folding locking member 13 to unlock the folding mechanism 1, push the backrest member 4 so that the rear base 22, the second folding member 12, the folding locking member 13, the backrest member 4, and the side wing member 5 are folded forward together by swinging. After folding, the front enclosure member 3, the front base 21, the rear base 22, the backrest member 4, and the side wing member 5 form an enclosure structure together. In the state of loading and using, the folding locking member 13 and the second folding member 12 tilt after flipping around the hinge point. The folding locking member 13 is embedded in the slot 14 under the action of gravity, and the folding mechanism 1 is locked so that the backrest member 4, the rear base 22, and the side wing member 5 cannot be folded backward. Pull the folding locking member 13 to unlock the folding mechanism 1, then flip the backrest member 4 backward and embed the folding locking member 13 in the slot 14. At this time, the rear base 22 is limited by the folding mechanism 1, and the seat enters the state of loading and using.

[0122] 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 switched from a passenger state to a cargo state, the hinge points of the first folding member 11 and the second folding member 12 of this embodiment are designed to be lower than the upper end surface of the base member 2.

[0123] In order to facilitate unlocking of the folding locking member 13, the first folding member 11 is connected to the front base 21, and the second folding member 12 is connected to the rear base 22. After the second folding member 12 is folded together with the rear base 22, it is easier to unlock in the loading state.

[0124] 7. A two-wheeled vehicle multifunctional child seat (second type) second embodiment

[0125] like Fig.19As shown, this embodiment provides a multifunctional child seat for a two-wheeled vehicle, comprising: a folding mechanism 1, a base member 2, a front enclosure member 3, a backrest member 4, and side wing members 5.

The folding locking member 13 is slidably connected to the second folding member 12, and a slot 14 is provided on the first folding member 11. The slot 14 can cooperate with the folding locking member 13. When the seat is used for carrying people, the one-way limiting folding mechanism 1 limits the unfolding angle of the backrest member 4, so that the rear base 22 and the backrest member 4 can support the children sitting on the seat. The slot 14 can also cooperate with the folding locking member 13. When the seat is used for carrying objects, the one-way limiting folding mechanism 1 prevents the seat from being transformed into the state of carrying people. When the seat is used for carrying objects, the front enclosure member 3 limits the maximum angle of the backrest member 4 to be folded forward, and the folding mechanism 1 limits the backward folding of the backrest member 4.

[0128] The difference from the first embodiment of the above-mentioned two-wheeled vehicle multifunctional child seat (second type) is that in this embodiment: the second folding member 12 and the front base member 21 are two types of parts made of different materials and connected to each other, the first folding member 11 and the rear base 22 are two types of parts made of different materials and connected to each other, and the backrest member 4 and the side wing member 5 are two parts formed in one piece from the same material. In this embodiment, the number of the first folding member 11 and the second folding member 12 is two, and the folding locking member 13 is slidably arranged on the second folding member 12, and the folding locking member 13 can slide horizontally left and right on the second folding member 12. When the rear base 22 is folded forward, the first folding member 11 and the folding locking member 13 are turned forward together around the hinge point.

[0129] In order to provide a fixing point for the safety belt and improve the safety of children when the seat is in use with passengers, the folding locking member 13 in this embodiment can also cooperate with the card slot 14 so that the folding mechanism 1 is bidirectionally limited when the seat is in use with passengers.

[0130] In combination with the five embodiments of the first two-wheeled vehicle multifunctional child seat described above, relevant personnel in the industry can also know at least three different forms of the second two-wheeled vehicle multifunctional child seat embodiments without any effort. The second two-wheeled vehicle multifunctional child seat does not rely on the rear clothes hanger of the two-wheeled vehicle, eliminates the influence of environmental characteristics, and the size restriction of the rear base is also lifted.

[0131] 8. A multifunctional child seat for a two-wheeled vehicle (third type) First embodiment

[0132] like Fig. 22 As shown, this embodiment provides a multifunctional child seat for a two-wheeled vehicle, comprising: a folding mechanism 1, a base member 2, a front enclosure member 3, a backrest member 4 and side wing members 5.

[0133] like Fig.23 As shown, the base member 2 includes a front base 21 and a rear base 22, and the rear base 22 is hinged to the front base 21 through a folding mechanism 1. The front enclosure member 3 is detachably connected to the front base 21, and the backrest member 4 is connected to the rear base connection 22. The front enclosure member 3 limits the maximum angle of the backrest member 4 to flip forward around the hinge point. When the backrest member 4 is folded forward and close to the front enclosure member 3, the front enclosure member 3, the front base 21, the rear base 22, and the backrest member 4 together form an enclosure structure. The side wing member 5 is connected to the left and right sides of the backrest member 4, and the side wing member 5 is used to laterally enclose the enclosure structure formed by the front enclosure member 3, the front base 21, the rear base 22, and the backrest member 4.

[0134] like Fig.24 As shown, the folding mechanism 1 includes a first folding member 11, a second folding member 12 and a folding locking member 13. The first folding member 11 is connected to the front base 21, and the second folding member 12 is connected to the rear base 22. The folding locking member 13 is hinged to the second folding member 12, and a slot 14 is provided on the first folding member 11. The folding locking member 13 can cooperate with the slot 14. The one-way limiting folding mechanism 1 in the state of carrying goods makes it impossible for the seat to be transformed into the state of carrying people. A positioning protrusion 15 is provided on the first folding member 11, and a positioning slot 16 is provided on the second folding member 12. The positioning protrusion 15 and the positioning slot 16 limit the maximum unfolding angle of the folding mechanism 1 in the state of carrying people. It should be noted that the positioning protrusion 15 and the positioning slot 16 limit the unfolding angle of the backrest member 4 and the rear base 22 in the state of carrying people, thereby ensuring that the seat is rideable no matter how it is installed on the two-wheeled vehicle, eliminating the influence of environmental characteristics.

[0135] When a child is not sitting on the seat, the partial structure of the folded seat forms an enclosed space and is limited by the folding lock 13, and the seat enters the state of loading. In the state of loading, the front enclosure 3 limits the forward folding of the backrest 4, and the folding lock 1 limits the backward folding of the backrest 4, so that the storage of items is realized. In the state of carrying people, the positioning protrusion 15 and the positioning slot 16 limit the folding mechanism 1, limit the maximum angle of the backward folding of the backrest 4 and the rear base 22, so that the child can sit on the seat.

[0136] 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 used for carrying objects instead of people, the hinge points of the first folding member 11 and the second folding member 12 of this embodiment are designed to be lower than the upper end surface of the base member 2, so that after the backrest member 4 and the rear base 22 are folded forward, the gap between the front base 21 and the rear base 22 is reduced. A smaller gap is conducive to the storage of articles accompanying the vehicle.

[0137] In this embodiment, the first folding member 11 is connected to the front base 21, and the second folding member 12 is connected to the rear base 22. After the second folding member 12 and the rear base 22 are folded forward together, it is more convenient to operate the folding locking member 13 in the loading state.

The first folding member 11 is provided with a slot 14, which 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 second folding member 12 is provided with a positioning protrusion 15, and the first folding member 11 is provided with a positioning slot 16. The positioning protrusion 15 and the positioning slot 16 limit the maximum unfolding angle of the folding mechanism 1 in the state of carrying people. The presence of the front enclosure 3 limits the maximum angle of the backrest member 4 to fold forward. After pushing the backrest member 4 to fold forward, the folding locking member 13 is operated to limit the folding mechanism 1 to realize the storage of the accompanying items.

[0142] Different from the first embodiment of the above-mentioned two-wheeled vehicle multifunctional child seat (third type): the front enclosure 3, the front base 21 and the second folding piece 12 of this embodiment are two parts integrally formed of the same material; the first folding piece 11 and the rear base 22 of this embodiment are two parts integrally formed of the same material.

[0143] In the state of passenger use, the forward folding of the folding mechanism 1 is not limited, which will cause the safety belt to lack a fixed point.
