Description

Technical Field

[0001] This invention relates to the field of child seats, and more particularly to a type of multifunctional child seat for two-wheeled vehicles and its folding safety device. Background Technology

[0002] Bicycles and electric bicycles are common modes of transportation for citizens to pick up and drop off children at school due to their ease of parking. Many cities require kindergarten children under six years old to have a fixed seat installed on the back of a bicycle or electric bicycle, and that they wear a safety helmet. The "Electric Bicycle Safety Technical Specification" (GB17761-2018) restricts technical parameters such as wheelbase and saddle length of electric bicycles, significantly limiting their carrying capacity. Adding a rear-mounted safety seat prevents the installation of a tail box, depriving safety helmets of a theft-proof storage space, which also limits the use of high-quality safety helmets. The use of front baskets on bicycles is also unpopular; on the one hand, carrying items in a front basket affects steering feel, and on the other hand, it is not aesthetically pleasing. Similarly, installing a fixed seat on the rear rack of a bicycle presents the problem of where to store helmets. Summary of the Invention

[0003] To address the challenge of simultaneously accommodating passenger carrying and cargo storage on two-wheeled vehicles such as bicycles and electric bicycles, this invention provides a multi-functional child seat for two-wheeled vehicles and its folding safety device. By folding down a portion of the multi-functional child seat to create an enclosed space and using the folding safety device to lock the folding mechanism, the multi-functional child seat can also carry cargo, achieving a dual-purpose function.

[0004] According to one aspect of the present invention, a first multi-functional child seat for a two-wheeled vehicle is provided, comprising: a folding mechanism, a base member, a front panel member, a backrest member, and side wings.

[0005] The folding mechanism includes a first folding member, a folding locking member, and a second folding member. The folding locking member is slidably disposed on the second folding member, or hinged to the second folding member, or detachably connected to the second folding member. The first folding member has a slot that can cooperate with the folding locking member to unidirectionally limit the folding mechanism in the loaded state, preventing the two-wheeled vehicle's multi-functional child seat from changing to a passenger-carrying state. It should be noted that: designing the folding locking member to slide obliquely on the second folding member can achieve self-locking of the folding mechanism; designing the folding locking member to be hinged to the second folding member, utilizing the center of gravity of the folding locking member, can achieve self-locking of the folding mechanism; designing a threaded folding locking member that can be detachably connected to the second folding mechanism can also achieve self-locking of the folding mechanism. Another aspect of the present invention also provides a folding safety device for a two-wheeled vehicle's multi-functional child seat, which can limit the folding locking member; the elastic element is not a necessary component to improve the reliability of the folding mechanism.

[0006] The base component includes a front base and a rear base. The rear base is hinged to the front base via 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 a non-motorized vehicle. 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 passenger-carrying state, the front base can be installed in reverse so that the child facing the rear 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, ensuring that the front base always has a position to be fixed to the rear rack when the first type of multi-functional child seat for two-wheeled vehicles is installed in reverse. After reverse installation, the rear base can be supported and limited by the rear rack of the two-wheeled vehicle. The "Safety Requirements and Test Methods for Imported and Exported Bicycle Child Seats" (GB / T 23160-2008) specifies the length of different types of child seats, including: the length of the A15 type rear seat is between 160mm and 220mm, and the length of the A22 type rear seat is between 170mm and 230mm. The seat length is less than the rear rack length, thus determining the maximum possible rear base length to be between 160 and 230 mm. The "Safety Requirements for Child Bicycle Seats" is still under review, and the range of maximum rear base lengths may change once the document is published.

[0007] The front baffle is fixed to the front base or detachably connected to the front base. The presence of the front baffle limits the maximum angle at which the backrest folds forward. The end face of the front baffle can be flat or curved, and its shape can enclose the enclosed structure formed by the backrest, side wings, and base. The size of the gap in the enclosure is not limited, as long as the helmet does not fall off.

[0008] The backrest is connected to the rear base. After the backrest folds forward and approaches the front baffle, the front baffle, front base, rear base, and backrest together form an enclosed structure. When used outdoors, this invention will face rain and snow. Making the backrest one-piece waterproof is beneficial for long-term storage. However, many people are accustomed to covering parked vehicles with rain gear, so making the backrest one-piece waterproof is not necessary; the holes in the backrest should be large enough to prevent helmets from falling out.

[0009] The side wings connect to the left and right sides of the backrest. The side wings enclose the enclosure formed by the front bumper, 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 molded from the same material, or they can be a combination of two parts made of the same or different materials. Outdoor use may involve rain and snow; making the side wings one-piece waterproof is beneficial for storing items for extended periods while carrying cargo. However, many people are accustomed to covering parked vehicles with rain gear, so making the side wings one-piece waterproof is not necessary.

[0010] The first type of multi-functional child seat for two-wheeled vehicles folds down to form an enclosed space, and a folding lock limits the folding mechanism, enabling the seat to carry cargo. In cargo-carrying mode, the front barrier prevents the backrest from folding forward, and the folding lock prevents the backrest from folding backward, thus ensuring reliable storage of items. In passenger-carrying mode, the folding lock is unlocked, and the backrest folds backward until it is stopped by the rear coat rack of the two-wheeled vehicle, at which point the first type of multi-functional child seat for two-wheeled vehicles enters passenger-carrying mode.

[0011] Furthermore, to address the issue of the backrest not being restricted from forward tilting during passenger use, which hinders the installation and use of seat belts, the above technical solution is improved: the folding locking component and the slot cooperate to unidirectionally restrict the folding mechanism during passenger use, thereby limiting the forward tilting of the backrest and preventing the first type of two-wheeled vehicle multi-functional child seat 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.

[0012] To eliminate the limitations imposed by environmental characteristics on the size of the rear base, according to one aspect of the present invention, a second type of multi-functional child seat for two-wheeled vehicles is provided, comprising: a folding mechanism, a base member, a front panel member, a backrest member, and side wings.

[0013] The folding mechanism includes a first folding component, a folding locking component, and a second folding component. The folding locking component is slidably disposed on the second folding component, detachably connected to the second folding component, or hinged to the second folding component. The first folding component has a slot that cooperates with the folding locking component to unidirectionally limit the folding mechanism's unfolding angle when in passenger-carrying mode; and unidirectionally limit the folding mechanism when carrying cargo, preventing the second type of two-wheeled multi-functional child seat from converting to passenger-carrying mode. Designing the folding locking component to slide obliquely on the second folding component achieves self-locking of the folding mechanism; designing the folding locking component to be hinged to the second folding component utilizes the center of gravity of the folding locking component to achieve self-locking of the folding mechanism; designing a threaded folding locking component that is detachably connected to the second folding mechanism also achieves self-locking of the folding mechanism. Another aspect of the invention provides a folding safety device for a multi-functional child seat for two-wheeled vehicles. This folding safety device can limit the folding locking element, and the elastic element is not a necessary component to improve the reliability of the folding mechanism. It should be noted that in the passenger-carrying state, the folding locking element limits and supports the backrest and rear base, thereby ensuring that the second type of multi-functional child seat for two-wheeled vehicles remains livable regardless of whether it is installed on a non-motorized vehicle, eliminating the limitation imposed by the rear rack of the two-wheeled vehicle on the length of the rear base.

[0014] The base component includes a front base and a rear base, with the rear base and the front base hinged together by a folding mechanism.

[0015] The front baffle is fixed to the front base or detachably connected to the front base. The presence of the front baffle limits the maximum angle at which the backrest folds forward. The end face of the front baffle can be flat or curved. Its end face shape can enclose the enclosed structure formed by the backrest, side wings, and base from the side. The size of the gap in the enclosure is not limited, as long as the helmet does not fall off.

[0016] The backrest is connected to the rear base. The maximum angle at which the backrest flips forward around the hinge point is limited by the front baffle. After the backrest folds forward and approaches the front baffle, the front baffle, the front base, the rear base, and the backrest together form an enclosed structure. When used outdoors, this invention will face rain and snow. Making the backrest one-piece waterproof would be beneficial for long-term storage of items. However, many people are accustomed to covering parked vehicles with rain gear, so making the backrest one-piece waterproof is not necessary; the holes in the backrest should be large enough to prevent helmets from falling out.

[0017] The side wings connect to the left and right sides of the backrest. The side wings enclose the enclosure formed by the front bumper, 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 molded from the same material, or they can be a combination of two parts made of the same or different materials. Outdoor use may involve rain and snow; making the side wings one-piece waterproof is beneficial for storing items for extended periods while carrying cargo. However, many people are accustomed to covering parked vehicles with rain gear, so making the side wings one-piece waterproof is not necessary.

[0018] The second type of multi-functional child seat for two-wheeled vehicles features a folding mechanism that creates an enclosed space and uses a folding lock to limit the folding action, enabling it to carry cargo. In cargo-carrying mode, the front barrier prevents the backrest from folding forward, while the folding lock, in conjunction with a slot, prevents the backrest from folding backward, thus allowing items to be stored. In passenger-carrying mode, the folding lock and slot prevent the backrest from folding backward, allowing the child to sit comfortably.

[0019] Furthermore, the position of the hinge center of the first and second folding components in passenger-carrying mode affects the size of the gap between the front and rear bases in cargo-carrying mode. When the hinge center is higher than the upper surface of the base, pushing the backrest forward will cause the front and rear bases to move further apart, increasing the gap and making it difficult to store items. Therefore, the above technical solution is further improved: the position of the hinge center of the first and second folding components is designed so that it is not higher than the upper surface of the base in passenger-carrying mode. In this way, after the backrest is folded forward, the relative position of the front and rear bases will further decrease or remain unchanged. Specifically, when the hinge center of the first and second folding components is between the upper and lower surfaces of the base: the portions of the front and rear bases above the hinge point move closer together; the portions below the hinge point move further apart. The position of the hinge center of the first and second folding parts is designed so that it is not higher than the upper surface of the base part. This reduces the gap between the front and rear bases when the item is in use, which is beneficial for storing small items.

[0020] Furthermore, when the second folding component is connected to the front base, the folding locking component is located below the front base, making its operation inconvenient. Therefore, the above technical solution is further improved: the first folding component is connected to the front base, and the second folding component is connected to the rear base. In this case, the folding locking component and the second folding component flip together with the rear base. When in use with a load, the position of the folding locking component is raised, facilitating its operation. The first folding component and the front base 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. Similarly, the second folding component and the rear base 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.

[0021] Optionally, if the backrest is not secured when the vehicle is in passenger-carrying mode, the seatbelt lacks anchor points, compromising child safety. To address this, the present invention provides a technical solution: designing a slot that cooperates with the folding locking mechanism, allowing the folding locking mechanism and the slot to work together to bidirectionally secure the folding mechanism when the vehicle is in passenger-carrying mode. The bidirectionally secured backrest can then secure the seatbelt. Depending on the shape of the folding locking mechanism, the number of slots is not limited to one or two.

[0022] According to one aspect of the present invention, a third type of multi-functional child seat for two-wheeled vehicles is provided, comprising: a folding mechanism, a base member, a front panel member, a backrest member, and side wings.

[0023] The folding mechanism includes a first folding component, a folding locking component, and a second folding component. The folding locking component is slidably mounted on the second folding component, detachably connected to the second folding component, or hinged to the second folding component. The first folding component has a slot that cooperates with the folding locking component to unidirectionally limit the folding mechanism in the loaded state, preventing the third type of two-wheeled vehicle multi-functional child seat from being converted to a passenger-carrying state. One of the first and second folding components has a positioning protrusion, and the other has a positioning slot. The positioning protrusion and positioning slot limit the maximum unfolding angle of the folding mechanism in the passenger-carrying state. In the passenger-carrying state, the positioning protrusion and positioning slot limit the unfolding angle of the backrest and rear base, thus ensuring that the seat remains livable regardless of how it is installed on a non-motorized vehicle, eliminating the influence of environmental characteristics. The invention designs a folding locking element that slides at an angle onto the second folding element, enabling self-locking of the folding mechanism. Alternatively, the folding locking element can be hinged to the second folding element, utilizing its center of gravity to achieve self-locking. A threaded folding locking element that can be detachably connected to the second folding mechanism also achieves self-locking. Another aspect of the invention provides a folding safety device for a two-wheeled vehicle's multi-functional child seat, which can limit the folding locking element; the elastic element is not a necessary component for improving the reliability of the folding mechanism.

[0024] The base component includes a front base and a rear base, with the rear base and the front base hinged together by a folding mechanism.

[0025] The front baffle is fixed to the front base or detachably connected to the front base. The presence of the front baffle limits the maximum angle at which the backrest folds forward. The end face of the front baffle can be flat or curved. Its end face shape can enclose the enclosed structure formed by the backrest, side wings, and base from the side. The size of the gap in the enclosure is not limited, as long as the helmet does not fall off.

[0026] The backrest is connected to the rear base. The maximum angle at which the backrest flips forward around the hinge point is limited by the front baffle. After the backrest folds forward and approaches the front baffle, the front baffle, the front base, the rear base, and the backrest together form an enclosed structure. When used outdoors, this invention will face rain and snow. Making the backrest one-piece waterproof would be beneficial for long-term storage of items. However, many people are accustomed to covering parked vehicles with rain gear, so making the backrest one-piece waterproof is not necessary; the holes in the backrest should be large enough to prevent helmets from falling out.

[0027] The side wings connect to the left and right sides of the backrest. The side wings enclose the enclosure formed by the front bumper, 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 molded from the same material, or they can be a combination of two parts made of the same or different materials. Outdoor use may involve rain and snow; making the side wings one-piece waterproof is beneficial for storing items for extended periods while carrying cargo. However, many people are accustomed to covering parked vehicles with rain gear, so making the side wings one-piece waterproof is not necessary.

[0028] The folding mechanism of the third type of multi-functional two-wheeled child seat creates an enclosed space, which is then limited by a folding lock, enabling the seat to carry cargo. In cargo-carrying mode, the front barrier limits the forward folding of the backrest, while the folding lock and slot limit the rearward folding, allowing for storage of items. In passenger-carrying mode, the positioning protrusion and positioning slot limit the maximum rearward folding angle of the backrest, thus ensuring a comfortable seating position for the child.

[0029] Furthermore, the position of the hinge center of the first and second folding components in passenger-carrying mode affects the size of the gap between the front and rear bases in cargo-carrying mode. When the hinge center is higher than the upper surface of the base, pushing the backrest forward will cause the front and rear bases to move further apart, increasing the gap and making it difficult to store items. Therefore, the above technical solution is further improved: the position of the hinge center of the first and second folding components is designed so that it is not higher than the upper surface of the base in passenger-carrying mode. In this way, after the backrest is folded forward, the relative position of the front and rear bases will further decrease or remain unchanged. Specifically, when the hinge center of the first and second folding components is between the upper and lower surfaces of the base: the portions of the front and rear bases above the hinge point move closer together; the portions below the hinge point move further apart. The position of the hinge center of the first and second folding parts is designed so that it is not higher than the upper surface of the base part. This reduces the gap between the front and rear bases when the item is in use, which is beneficial for storing small items.

[0030] Furthermore, when the second folding component is connected to the front base, the folding locking component is located below the front base, making its operation inconvenient. Therefore, the above technical solution is further improved: the first folding component is connected to the front base, and the second folding component is connected to the rear base. In this case, the folding locking component and the second folding component flip together with the rear base. When in use with a load, the position of the folding locking component is raised, facilitating its operation. The first folding component and the front base 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. Similarly, the second folding component and the rear base 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.

[0031] Optionally, if the backrest is not secured when the vehicle is in passenger-carrying mode, the seatbelt lacks anchor points, compromising child safety. To address this, the present invention provides a technical solution: designing a slot that cooperates with the folding locking mechanism, allowing the folding locking mechanism and the slot to work together to bidirectionally secure the folding mechanism when the vehicle is in passenger-carrying mode. The bidirectionally secured backrest can then secure the seatbelt. Depending on the shape of the folding locking mechanism, the number of slots is not limited to one or two.

[0032] Optionally, a lifting structure is introduced, allowing the backrest to be height-adjustable to accommodate children of different heights. Specifically, in some embodiments, it also includes: a rear vertical fixing frame, a rear vertical movement frame, and a lifting locking component.

[0033] The rear vertical fixing frame has a first limiting hole. 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 can be directly connected to the first or second folding piece, thereby indirectly connecting to the rear base; the rear vertical fixing frame and the rear base can be two parts integrally formed from 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 they can be a combination of two parts of the same material or different materials.

[0035] The lifting and locking mechanism includes a lifting and locking body, a locking pin, and an elastic element. The lifting and locking body slides onto the rear vertical fixing frame, and the backrest is fixed to the lifting and locking body. The lifting and locking body and the backrest can be two parts integrally formed from the same material, or they can be a combination of two parts made of the same material or different materials. The locking pin slides onto the lifting and locking body, and under the action of the elastic element, the locking pin simultaneously engages with the first and second limiting holes to achieve the lifting and locking function. The height-adjustable backrest provides more adequate back support for children. The side wings rise and fall together with the backrest; when the backrest is positioned sufficiently to support the child's head, the side wings can also protect the child's head from the side.

[0036] When storing items for extended periods while carrying cargo, theft prevention is a concern; when carrying passengers, the folding locking mechanism can be accidentally unlocked. Therefore, according to another aspect of the present invention, a folding safety device for a multi-functional child seat in a two-wheeled vehicle 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 the multi-functional child seat for a two-wheeled vehicle as described in any one of claims 1 to 11.

[0037] The longitudinal connector is fixed to the folding mechanism for mounting the rear tie rod. The longitudinal connector can be hollow or solid, and its extension path can be straight or curved.

[0038] The rear pull rod is slidably mounted on the longitudinal connecting member and indirectly connected to the folding locking member via 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 horizontal connecting member to achieve the anti-theft function. The lock plate is connected to the lock body and is used to directly or indirectly limit the flip-up locking member. The lock plate can be used to limit the pull rod or the front and rear connecting rods, and indirectly limit the flip-up locking member.

[0040] The introduction of the lateral connector provides a wider range of connection points for the lock body. When there is more than one longitudinal connector, the lateral connector can simultaneously connect multiple longitudinal connectors, thus reinforcing the seat.

[0041] When the folding locking element slides longitudinally, the rear pull rod slides back and forth along with it, driven by the front and rear connecting rods. When the folding locking element rotates around the hinge point, the rear pull rod slides back and forth along with it, driven by the front and rear connecting rods. When the folding locking element slides laterally, the rear pull rod slides laterally left and right along with it, driven by the front and rear connecting rods. When the folding locking element is screwed into the first folding element, the rear connecting rod is sleeved on the folding locking element. At this time, the rear pull rod and the front and rear connecting rods do not rotate, and the rear pull rod slides laterally along with it, driven by the front and rear connecting rods.

[0042] The introduction of a folding safety device can not only prevent theft of items when the vehicle is in use with cargo, but also prevent the folding mechanism from being accidentally unlocked when the vehicle is in use with passengers. Attached Figure Description

[0080] For ease of description, the terms "front," "rear," "left," and "right" used below are determined based on the child's first-person perspective while riding the vehicle and are unrelated to the left-right direction of the accompanying drawings. For the sake of brevity, the non-motorized multi-functional child seat provided in the following embodiments can be simply referred to as a "seat."

[0081] 1. First embodiment of a multi-functional child seat for non-motorized vehicles

[0082] like Figure 1 As shown, this embodiment provides a multi-functional child seat for non-motorized vehicles, including: a folding mechanism 1, a base 2, a front panel 3, a backrest 4, and side wings 5.

[0083] like Figure 2 As shown, the base component 2 includes a front base 21 and a rear base 22, which are hinged together by a folding mechanism 1. The rear base 22, the backrest component 4, and the side wing components 5 can all fold forward together by swinging. There are two side wing components 5, which are respectively connected to the left and right sides of the backrest component 4. The backrest component 4 is connected to the rear end of the rear base component 22, and the front baffle component 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 to unidirectionally limit the folding mechanism 1 in the cargo-carrying state, preventing the seat from changing to the passenger-carrying state. The presence of the front baffle 3 limits the maximum angle of the backrest 4 folding forward. In the cargo-carrying state, operating the folding locking member 13 to enter the slot 14 allows for the storage of items in the vehicle.

[0085] In this embodiment, the seat is installed facing forward, with the child facing the front of the two-wheeled vehicle when in passenger use. The front base 21 is connected to the rear coat rack of the two-wheeled vehicle. If the seat is installed facing forward, the length of the rear coat rack is insufficient to support and limit the rear base 22 when in passenger use. In this case, the seat can be installed facing backward. The longitudinal length of the rear base 22 is less than the longitudinal length of the rear coat rack, ensuring that when the child seat of this embodiment is installed facing backward, the front base 21 is always fixed to the rear coat rack, and the rear base 22 can be supported and limited by the rear coat rack.

[0086] In this embodiment, the folding mechanism 1 is positioned below the upper surface of the base member 2. There are two first folding members 11 and two second folding members 12, and one folding locking member 13 with a circular cross-section. The folding locking member 13 slides on the second folding member 12 and can slide back and forth on the second folding member 12. The direction of the back and forth sliding of the folding locking member 13 is designed to be slightly inclined, so that the folding locking member 13 can maintain its position under the action of gravity and always be embedded in the slot 14 of the first folding member 11. When the rear base 22 folds 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 3 are two types of parts made of different materials and are rigidly connected to each other. The second folding member 12 and the rear base 22 are two types of parts made of different materials and are rigidly connected to each other. The backrest member 4 and the side wing member 5 are two types of parts made of different materials, and the side wing member 5 is fixed to the backrest member 4. The front baffle member 3 and the front base 21 are two types of parts made of different materials, and the front baffle member 3 is pluggably connected to the front base 21.

[0088] The seat provided in this embodiment has two usage states: one is the passenger-carrying usage state, as shown below. Figure 2 As shown, another type is the cargo-carrying usage state, such as... Figure 3 As shown. The specific process of the two state transitions is as follows:

[0089] When the folding locking member 13 is unlocked in passenger-carrying mode, the backrest member 4 is pushed so that 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 folds and approaches the front baffle member 3, the front baffle member 3, the front base 21, the rear base 22, the backrest member 4, and the side wing member 5 together form an enclosing 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 inserted into the slot 14 of the first folding member 11, so that the current 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 mode.

[0090] When in cargo-carrying mode, pull the folding lock 13 and then fold the backrest 4 backward so that the rear base 22 is supported by the rear coat rack of the two-wheeled vehicle, and the seat enters the passenger-carrying mode.

[0091] Equipping the seat with a seatbelt in passenger mode prevents young children from being thrown from the seat during emergency braking. To provide a reliable anchor point for the seatbelt, the slot 14 on the first folding member 11 in this embodiment can cooperate with the folding locking member 13 to unidirectionally limit the folding mechanism 1 in passenger mode, preventing the seat from changing from passenger mode to cargo mode. Specifically, as follows... Figure 2 As shown, the card slot 14 can cooperate with the folding locking member 13 in the manned use state to limit the folding mechanism 1. In this embodiment, there are two card slots 14.

[0092] 2. Second embodiment of the first type of multi-functional child seat for non-motorized vehicles

[0093] This embodiment provides a multi-functional child seat for a two-wheeled vehicle, including: a folding mechanism 1, a base 2, a front panel 3, a backrest 4, and side wings 5.

[0094] The side wing 5 is fixed to the left and right sides of the backrest 4, which is connected to the rear end of the rear base 22. The front baffle 3 is fixed to the front end of the front base 21. The base 2 includes a front base 21 and a rear base 22, which are hinged by a folding mechanism 1. The rear base 22, the backrest 4, and the side wing 5 can all fold forward together by swinging. The longitudinal length of the rear base 22 is less than the longitudinal length of the rear coat rack of the two-wheeled vehicle. The front base 21 is fixed to the rear coat rack of the two-wheeled vehicle.

[0095] To more clearly show the structure of the folding mechanism 1, the folding locking piece on the left side is moved down for drawing purposes.

[0096] 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 slides on the second folding member 12 and slides laterally on 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 to unidirectionally limit the folding mechanism 1 in the cargo-carrying state, preventing the seat from changing to the passenger-carrying state. The presence of the front baffle 3 limits the maximum angle of the backrest 4 folding forward. After the backrest 4 is folded forward, the folding mechanism 1 is locked by the folding locking member 13, thus enabling the storage of items in the vehicle.

[0097] The difference from Embodiment 1 above is that: in this embodiment, the backrest 4 and side wing 5 are two parts integrally formed from the same material, and the front baffle 3 and front base 21 are two parts integrally formed from the same material. The first folding member 11 and the rear base 22 are two parts integrally formed from the same material, and the second folding member 12 and the front base 21 are two parts integrally formed from the same material. The front baffle 3 and the front base 21 partially enclose the front and bottom, respectively. The folding locking member 13 slides on the second folding member 12 and slides laterally on the second folding member 12. The lateral cross-sectional shape of the folding locking member 13 is rectangular. The folding mechanism 1 is located on the upper surface of the base member 2. In this embodiment, the child seat is installed facing forward on the rear rack of the two-wheeled vehicle, and the child faces the front of the two-wheeled vehicle when riding.

[0098] Equipping the seat with a seatbelt in passenger-carrying mode prevents young children from being thrown from the seat during emergency braking. To provide a reliable anchor point for the seatbelt, the slot 14 on the first folding member 11 in this embodiment can cooperate with the folding locking member 13 to unidirectionally limit the folding mechanism 1 in passenger-carrying mode, preventing the seat from changing from passenger-carrying mode to cargo-carrying mode. Specifically, the slot 14 can cooperate with the folding locking member 13 in passenger-carrying mode to limit the folding mechanism 1. This embodiment has two slots 14.

[0099] 3. Third embodiment of the first type of multi-functional child seat for non-motorized vehicles

[0100] like Figure 4 As shown, this embodiment provides a multi-functional child seat for a two-wheeled vehicle, including: a folding mechanism 1, a base 2, a front panel 3, a backrest 4, and side wings 5.

[0101] like Figure 5 As shown, the side wings 5 ​​are fixed to the left and right sides of the backrest 4. The base 2 includes a front base 21 and a rear base 22. The backrest 4 is connected to the rear end of the rear base 22, and the front baffle 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 4, and the side wings 5 ​​can all fold forward together by swinging. Figure 4 As shown, the longitudinal length of the rear base 22 is less than the longitudinal length of the rear clothes rack of the two-wheeled vehicle, and the front base 21 is fixed to the rear clothes rack of the two-wheeled vehicle.

[0102] 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 mounted on 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 to unidirectionally limit the folding mechanism 1 in the cargo-carrying state, preventing the seat from changing to the passenger-carrying state. The presence of the front baffle 3 limits the maximum angle at which the backrest 4 folds forward. After the backrest 4 folds forward, operating the folding locking member 13 to limit the folding mechanism 1 allows for the storage of items in the vehicle.

[0103] The difference between this embodiment and the second embodiment of the first type of multi-functional child seat for non-motorized vehicles is that the folding locking member 13 is slidably mounted on the second folding member 12 and moves laterally to the left and right; the child seat in this embodiment is installed in the reverse direction, with the child facing the rear of the two-wheeled vehicle. By sliding the folding locking member 13 laterally to disengage it from the slot of the first folding member 11, the restriction on the folding mechanism 1 can be released. Pushing the backrest member 4, side wing member 5, rear base 22, and first folding member 11 together, they fold forward to form an enclosing structure. Then, the folding locking member 13 and the slot 14 are used to lock the folding mechanism 1, and the seat enters the cargo-carrying state.

[0104] Equipping the seat with a seatbelt in passenger mode prevents young children from being thrown from the seat during emergency braking. To provide a reliable anchor point for the seatbelt, the slot 14 on the first folding member 11 in this embodiment can cooperate with the folding locking member 13 to unidirectionally limit the folding mechanism 1 in passenger mode, preventing the seat from changing from passenger mode to cargo mode. Specifically, as follows... Figure 5 As shown, the card slot 14 can cooperate with the folding locking member 13 in the manned use state to limit the folding mechanism 1. In this embodiment, there are two card slots 14.

[0105] 4. Fourth embodiment of the first type of multi-functional child seat for non-motorized vehicles

[0106] like Figure 7 As shown, this embodiment provides a multi-functional child seat for a two-wheeled vehicle, including: a folding mechanism 1, a base 2, a front panel 3, a backrest 4, and side wings 5.

[0107] like Figure 8 As shown, the side wings 5 ​​are fixed to the left and right sides of the backrest 4. The base 2 includes a front base 21 and a rear base 22. The backrest 4 is connected to the rear end of the rear base 22, and the front baffle 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 4, and the side wings 5 ​​can all fold forward together by swinging. Figure 7 As shown, the longitudinal length of the rear base 22 is less than the longitudinal length of the rear coat rack of the two-wheeled vehicle, and the front base 21 is fixed to the rear coat rack of the two-wheeled vehicle.

[0108] like Figure 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. The first folding member 11 is provided with a slot 14, which can 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. The presence of the front bulkhead 3 limits the maximum angle of the backrest 4 folding forward. After the backrest 4 is folded forward, the folding mechanism 1 is locked by the folding locking member 13, thus enabling the storage of items in the vehicle.

[0109] The difference between this embodiment and the first embodiment of the first type of non-motorized vehicle multi-functional child seat is that: the folding locking member 13 of this embodiment is hinged to the second folding member 12, and the folding locking member 13 swings into the slot 14 on the first folding member 11 under the action of gravity to achieve the limiting function; the front guard 3 of this embodiment is fixed to the front base 21.

[0110] Equipping car seats with seat belts when in use with passengers can prevent young children from being thrown from the seat during emergency braking. For example... Figure 8 As shown, in order to provide a reliable fixing point for the seat belt, the slot 14 on the first folding member 11 in 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.

[0111] 5. Fifth embodiment of the first type of multi-functional child seat for non-motorized vehicles

[0112] like Figure 10As shown, this embodiment provides a multi-functional child seat for a two-wheeled vehicle, including: a folding mechanism 1, a base 2, a front panel 3, a backrest 4, and side wings 5.

[0113] like Figure 11 As shown, the base component 2 includes a front base 21 and a rear base 22. Side wings 5 ​​are fixed to the left and right sides of the backrest component 4, which is connected to the rear end of the rear base 22. The front baffle 3 is fixed to the front end of the front base 21. The front base 21 and the rear base 22 are hinged together by a folding mechanism 1. The rear base 22, backrest component 4, and side wings 5 ​​can all fold forward together by swinging. Figure 10 As shown, the longitudinal length of the rear base 22 is less than the longitudinal length of the rear coat rack of the two-wheeled vehicle, and the front base 21 is fixed to the rear coat rack of the two-wheeled vehicle.

[0114] like Figure 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 slides on the second folding member 12 and slides longitudinally back and forth on 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 to unidirectionally limit the folding mechanism 1 in the cargo-carrying state, preventing the seat from changing to the passenger-carrying state. The presence of the front bulkhead 3 limits the maximum angle of the backrest 4 folding forward. After the backrest 4 is folded forward, the folding locking member 13 can be used to limit the folding mechanism 1 to store items.

[0115] The difference between this embodiment and the first embodiment of the first type of multifunctional child seat for non-motorized vehicles is that: the front baffle 3 and the front base 21 are two parts integrally formed from the same material; the front baffle 3 has holes for children to hold on to; the front base 21 has a leg clearance notch for children to place their legs; there is one first folding piece 11 and one second folding piece 12; the first folding piece 11 is connected to the rear base 22, and the second folding piece 12 is connected to the front base 21; the first folding piece 11 and the rear base 22 are two parts integrally formed from the same material, and the second folding piece 12 and the front base 21 are two parts integrally formed from the same material; the folding locking piece 13 has a rectangular cross-section; under the action of friction, the folding locking piece 13 can be held in the slot 14.

[0116] In passenger-carrying mode, equipping the seat with a seatbelt can prevent children from being thrown from the seat during emergency braking. To provide a reliable anchor point for the seatbelt, the slot 14 on the first folding member 11 in this embodiment can cooperate with the folding locking member 13 to unidirectionally limit the folding mechanism 1 in passenger-carrying mode, preventing the seat from changing from passenger-carrying mode to cargo-carrying mode. Specifically, as shown below... Figure 11 As shown.

[0117] 6. Sixth embodiment of the first type of multi-functional child seat for non-motorized vehicles

[0118] like Figure 13 As shown, this embodiment provides a multi-functional child seat for a two-wheeled vehicle, including: a folding mechanism 1, a base 2, a front panel 3, a backrest 4, and side wings 5.

[0119] like Figure 14 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 fixed to the front end of the front base 21, and the side wings 5 ​​are fixed 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 13 As shown, the longitudinal length of the rear base 22 is less than the longitudinal length of the rear coat rack of the two-wheeled vehicle, and the front base 21 is connected to the rear coat rack of the two-wheeled vehicle.

[0120] 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 detachably 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 to unidirectionally limit the folding mechanism 1 in the cargo-carrying state, preventing the seat from changing to the passenger-carrying state. After the backrest 4 is folded forward, the folding locking member 13 can be operated to lock the folding mechanism 1 and store the items in the vehicle.

[0121] The difference between this embodiment and the first embodiment of the first type of multi-functional child seat for non-motorized vehicles is that: the front barrier 3 and the front base 22 are two parts integrally formed from the same material, the first folding part 11 and the rear base 22 are two parts integrally formed from the same material, the second folding part 12 and the front base 21 are two parts integrally formed from the same material; the folding locking part 13 is a bolt that is detachably connected to the second folding part 12.

[0122] As can be seen from the above six embodiments, in both passenger-carrying and cargo-carrying states, the folding locking member 13 can be designed to slide at an angle onto the second folding member 12, using gravity to allow the folding locking member 13 to slide and enter the slot 14, thereby limiting the folding mechanism 1; alternatively, the friction between the folding locking member 13 and the second folding member 12 can be used to limit 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 limit the folding mechanism 1; or a bolt-shaped folding locking member 13 can be designed to screw into the first folding member 11, thereby limiting the folding mechanism 1.

[0123] 7. First embodiment of the second type of multi-functional child seat for non-motorized vehicles

[0124] 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 panel 3, a backrest 4, and side wings 5.

[0125] like 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, and the side wings 5 ​​are connected to the left and right sides of the backrest component 4. The front baffle component 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. The rear base 22, the backrest component 4, and the side wings 5 ​​can all fold forward together by swinging.

[0126] like Figure 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. 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, restricting the unfolding angle of the backrest member 4 so that the rear base 22 and the backrest member 4 can support the child sitting in it. 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 member 4, and the folding mechanism 1 limits the rearward folding of the backrest member 4.

[0127] In this embodiment, the first folding member 1 and the front base member 21 are two types of parts made of different materials and are connected to each other. The second folding member 12 and the rear base 22 are two types of parts made of different materials and are connected to each other. The backrest member 4 and the side wing member 5 are 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. The folding locking member 13 is slidably disposed on the second folding member 12 and slides longitudinally back and forth on the second folding member 12. The sliding direction of the folding locking member 13 is inclined to a certain extent, so that the folding locking member 13 is embedded in the slot 14 under the action of gravity. When the rear base 22 folds forward, the second folding member 12 and the folding locking member 13 fold forward together around the hinge point.

[0128] The seat provided in this embodiment of the invention has two usage states: one is a passenger-carrying usage state, such as... Figure 17 As shown; the other is the cargo usage status, such as... Figure 18As shown. The specific process of the two state transitions is as follows: Pulling the folding locking piece 13 unlocks the folding mechanism 1, and 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 baffle 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. In the cargo-carrying state, the folding locking piece 13 and the second folding piece 12 tilt after flipping around the hinge point. Under the action of gravity, the folding locking piece 13 embeds into the slot 14 and locks the folding mechanism 1, preventing the backrest piece 4, the rear base 22, and the side wing piece 5 from folding backward. Pulling the folding locking piece 13 unlocks the folding mechanism 1, and then flipping the backrest piece 4 backward and embedding 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.

[0129] To address the issue of the gap between the front base 21 and the rear base 22 widening after the seat transitions from passenger use to cargo use, the hinge point of the first folding member 11 and the second folding member 12 in this embodiment is designed to be lower than the upper surface of the base member 2.

[0130] To facilitate unlocking the folding locking member 13, 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. The second folding member 12 folds together with the rear base 22, making it easier to unlock when the device is in use with cargo.

[0131] 8. Second embodiment of the second type of multi-functional child seat for non-motorized vehicles

[0132] 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 panel 3, a backrest 4, and side wings 5.

[0133] like 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 detachably connected to the front base 21. The 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 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.

[0134] like Figure 21As 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, restricting the unfolding angle of the backrest member 4 so that the rear base 22 and the backrest member 4 can support the seated 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 member 4, and the folding mechanism 1 limits the rearward folding of the backrest member 4.

[0135] The difference between this embodiment and the first embodiment of the second type of multi-functional child seat for non-motorized vehicles 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; 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, there are two of each of the first folding member 11 and the second folding member 12. The folding locking member 13 is slidably disposed on the second folding member 12 and can slide laterally left and right on the second folding member 12. When the rear base 22 folds forward, the first folding member 11 and the folding locking member 13 flip forward together around the hinge point.

[0136] 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 also cooperate with the slot 14 to make the folding mechanism 1 bidirectionally limited when it is in use with passengers.

[0137] Based on the six embodiments of the first type of multi-functional child seat for non-motorized vehicles described above, those skilled in the art can also learn about at least four different embodiments of the second type of multi-functional child seat for non-motorized vehicles without any effort on their part. The second type of multi-functional child seat for two-wheeled vehicles eliminates the need for a rear rack on the two-wheeled vehicle, thus removing the influence of environmental characteristics, and also freeing up the size limitations of the rear base.

[0138] 9. First embodiment of the third type of multi-functional child seat for non-motorized vehicles

[0139] like Figure 22 As shown, this embodiment provides a multi-functional child seat for non-motorized vehicles, including: a folding mechanism 1, a base 2, a front panel 3, a backrest 4, and side wings 5.

[0140] like Figure 23As shown, the base component 2 includes a front base 21 and a rear base 22, with the rear base 22 hinged to the front base 21 via a folding mechanism 1. A front baffle 3 is detachably connected to the front base 21, and a backrest 4 is connected to the rear base connection 22. The front baffle 3 limits the maximum angle at which the backrest 4 flips forward around the hinge point. When the backrest 4 folds forward and approaches the front baffle 3, the front baffle 3, the front base 21, the rear base 22, and the backrest 4 together form an enclosing structure. Side wings 5 ​​are connected to the left and right sides of the backrest 4, and the side wings 5 ​​are used to provide lateral enclosure for the enclosing structure formed by the front baffle 3, the front base 21, the rear base 22, and the backrest 4.

[0141] like Figure 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. The first folding member 11 has a slot 14, which cooperates with the slot 14 to unidirectionally limit the folding mechanism 1 in the cargo-carrying state, preventing the seat from changing to a passenger-carrying state. The first folding member 11 has a positioning protrusion 15, and the second folding member 12 has 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 passenger-carrying state. It should be noted that the positioning protrusion 15 and the positioning slot 16 limit the unfolding angle of the backrest 4 and the rear base 22 in the passenger-carrying state, thereby ensuring that the seat is rideable regardless of its installation on a non-motorized vehicle and eliminating the influence of environmental characteristics.

[0142] When the child is not in the seat, the folding seat structure forms an enclosed space and is locked by the folding lock 13, allowing the seat to be used for carrying cargo. In this cargo-carrying state, the front barrier 3 limits the forward folding of the backrest 4, and the folding lock 1 limits the rearward folding of the backrest 4, thus enabling the storage of items. In the passenger-carrying state, the positioning protrusion 15 and the positioning slot 16 limit the folding mechanism 1 and restrict the maximum rearward folding angle of the backrest 4 and the rear base 22, thus allowing the child to sit in the seat.

[0143] In this embodiment, to address the issue of the increased gap between the front base 21 and the rear base 22 after the seat transitions from passenger-carrying to cargo-carrying mode, the hinge points of the first folding member 11 and the second folding member 12 are designed to be lower than the upper surface of the base member 2. This reduces the gap between the front base 21 and the rear base 22 after the backrest member 4 and the rear base 22 are folded forward. A smaller gap facilitates the storage of items carried in the vehicle.

[0144] 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 fold forward together, it is more convenient to operate the folding locking member 13 when the load is in use.

[0145] 10. Second embodiment of the third type of multi-functional child seat for non-motorized vehicles

[0146] like Figure 25 As shown, this embodiment provides a multi-functional child seat for a two-wheeled vehicle, including: a folding mechanism 1, a base 2, a front panel 3, a backrest 4, and side wings 5.

[0147] like Figure 26 As shown, the base component 2 includes a front base 21 and a rear base 22. The front baffle 3 is fixed to the front end of the front base 21, the backrest 4 is connected to the rear end of the rear base 22, and the side wings 5 ​​are fixed to the left and right sides of the backrest 4. The front base 21 and the rear base 22 are hinged by the folding mechanism 1, and the rear base 21, the backrest 4, and the side wings 5 ​​can all fold forward together by swinging.

[0148] like Figure 27 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 a bolt that detachably connects to the second folding member 12. The first folding member 11 has a slot 14 that cooperates 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. The second folding member 12 has a positioning protrusion 15, and the first folding member 11 has 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 passenger-carrying state. The presence of the front baffle 3 limits the maximum forward folding angle of the backrest 4. After pushing the backrest 4 forward to fold, operating the folding locking member 13 to limit the folding mechanism 1 allows for the storage of items in the vehicle.

[0149] Unlike the first embodiment of the third type of multi-functional child seat for non-motorized vehicles mentioned above: in this embodiment, the front barrier 3, the front base 21, and the second folding member 12 are two parts integrally formed from the same material; in this embodiment, the first folding member 11 and the rear base 22 are two parts integrally formed from the same material.

[0150] When the seat is in passenger-carrying mode, the forward folding of the folding mechanism 1 is not limited, which will result in the seat belt lacking a fixing point. In order to improve the safety of the seat when it is in passenger-carrying mode, in this embodiment, the folding locking member 13 is designed to cooperate with the slot 14 to limit the forward folding of the backrest member 4 when it is in passenger-carrying mode.

[0151] 11. Third embodiment of the third type of multi-functional child seat for non-motorized vehicles

[0152] like Figure 28 As shown in the figure, this embodiment provides a multi-functional child seat for a two-wheeled vehicle, including: a folding mechanism 1, a base 2, a front panel 3, a backrest 4, and side wings 5.

[0153] like Figure 29 As shown, the base component 2 includes a front base 21 and a rear base 22, which are hinged together by a folding mechanism 1. A front baffle 3 is fixed to the front end of the front base 21, a backrest 4 is connected to the rear end of the rear base 22, and side wings 5 ​​are fixed to the left and right sides of the backrest 4. The rear base 22, backrest 4, and side wings 5 ​​can all fold forward together by swinging.

[0154] like Figure 29 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 longitudinally slidably mounted on the second folding member 12. The first folding member 11 has a slot 14, which cooperates 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. The first folding member 11 has a positioning protrusion 15, and the second folding member 12 has 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 passenger-carrying state. The presence of the front baffle 3 limits the maximum forward folding angle of the backrest 4. By folding the backrest 4 forward and operating the folding locking member 13 to lock the folding mechanism 1, items can be stored in the vehicle.

[0155] To provide adequate back or head support for children of different heights, this embodiment introduces: a rear vertical fixing frame 6, a rear vertical movement frame 7, and a lifting locking component 8, so that the backrest 4 can be adjusted in height to accommodate children of different heights.

[0156] like Figure 30 As shown, the bottom end of the rear vertical fixing frame 6 is directly fixed to the rear base 22, and the rear vertical fixing frame 6 has a limiting hole 61. The rear vertical moving frame 7 slides on the rear vertical fixing frame 6, and the rear vertical moving frame 7 has a limiting hole 71. The backrest 4 is fixed to the rear vertical moving frame 7. In this embodiment, the rear vertical moving frame 7 and the backrest 4 are two parts made of different materials.

[0157] like Figure 31As shown, the lifting and locking mechanism comprises a lifting and locking body 80, a locking pin 81, and an elastic element 82. The lifting and locking body 80 is slidably mounted on the rear vertical fixing frame 6, and the backrest 4 is fixed to the lifting and locking body 80. The lifting and locking body 80 and the backrest 4 are two parts made of different materials connected to each other. The locking pin 81 is slidably mounted on the lifting and locking body 80, and under the action of the elastic element 82, the locking pin 81 simultaneously engages with the first limiting hole 61 and the second limiting hole 71 to achieve the lifting and locking function. The height-adjustable backrest 4 can provide more adequate back or head support for children. When the position of the backrest 4 is sufficient to support the child's head, the side wings 5 ​​can also protect the child's head from the side.

[0158] 12. Fourth embodiment of the third type of multi-functional child seat for non-motorized vehicles

[0159] The difference between this embodiment and the third embodiment of the multi-functional non-motorized vehicle child seat is that the rear vertical movement frame 7, the lifting locking main body 80, and the backrest 4 are three parts integrally molded from the same material. Specifically, as follows... Figure 32 As shown.

[0160] 13. First embodiment of the folding safety device

[0161] The first embodiment of the folding safety device is as follows: Figure 33 As shown, it includes: a rear pull rod 17, a front and rear connecting rod 18, a longitudinal connecting piece 19, a transverse connecting piece 20, a lock body 91, a lock plate 92, and the seat described in the third embodiment of the third type of non-motorized vehicle multi-functional child seat.

[0162] The longitudinal connector 19 is fixed to the second folding member 12 and connected to the rear vertical fixing frame 7. The rear pull rod 17 is slidably mounted on the longitudinal connector 19 and indirectly connected to the folding locking member 13 through the front and rear connecting rods 18. The movement of the folding locking member 13 is transmitted to the rear pull rod 17 through the front and rear connecting rods 18, and the rear pull rod 17 slides longitudinally back and forth under the drive of the front and rear connecting rods 18.

[0163] The transverse connector 20 is connected to the longitudinal connector 19 and is used to install the lock body 91. In this embodiment, the transverse connector 20 is connected to two longitudinal connectors 19 at the same time, which can reinforce the seat.

[0164] The lock body 91 is fixed to the transverse connecting member 20, and the lock plate 92 is connected to the lock body 91. Operating the lock body 91 causes the lock plate 92 to move, and the limit lever 17 can limit the flip-lock member 13 as well.

[0165] The introduction of a folding safety device solves both the problem of preventing theft when storing items for extended periods while carrying cargo and the problem of improving the reliability of the folding mechanism when carrying passengers.

[0166] 14. A second embodiment of the folding safety device

[0167] like Figure 34 As shown, unlike the first embodiment of the folding safety device, in this embodiment: the folding locking member 13 is hinged to the second folding member 12; the slot 14 can cooperate with the folding locking member 13 to limit the folding mechanism 1 in both the passenger and cargo use states; one end of the front and rear connecting rod 18 is hinged to the folding locking member 13, and the other end is fixed to the rear pull rod 17.

[0168] 15. A third embodiment of the folding safety device

[0169] like Figure 35 and Figure 36 As shown, unlike the first embodiment of the folding safety device described above, in this embodiment, the second folding member 12 is connected to the front base 21, and the folding locking member 13 is a bolt that is detachably connected to the second folding member 12; the first folding member 11 is connected to the rear base, and a slot 14 is provided on it, the slot 14 being two round holes; the rear pull rod 17 is slid laterally on the longitudinal connecting member 19, one end of the front and rear connecting rods 18 is sleeved on the folding locking member 13, and the other end is fixed to the rear pull rod 17; when the folding locking member 13 is rotated to adjust its depth, the front and rear connecting rods 18 sleeved on the folding locking member 13, together with the rear pull rod 17, move laterally.

[0170] In this embodiment, there is one longitudinal connector 19. The locking plate 92 is fixed to the lock body 91, and the lock body 91 is fixed to the longitudinal connector 19 via the transverse connector 20. By manipulating the lock body 91, the locking plate 92 is rotated, which restricts the transverse movement of the front and rear connecting rods 18, thereby limiting the folding locking member 13. After being limited, the folding locking member 13 cannot be unscrewed from the first folding member 11, which improves the reliability of the folding mechanism 1 in the passenger-carrying state and realizes the anti-theft storage of items in the vehicle in the cargo-carrying state.

[0171] This invention provides a multi-functional child seat for two-wheeled vehicles with two usage modes, catering to both passenger and cargo needs when installed in a rear-mounted child seat. To achieve these objectives, a folding mechanism 1 is an indispensable technical feature. The folding mechanism 1 has a limiting function, allowing the multi-functional child seat to remain in either passenger or cargo-carrying mode. All four independent claims in this application include this specific technical feature of the folding mechanism 1. The first three independent claims outline different structures of the folding mechanism 1, providing three types of multi-functional child seats for two-wheeled vehicles. The fourth independent claim expands upon the folding mechanism 1, making its unlocking operation more convenient and its limiting function more reliable. Simultaneously, it also enables the seat to be used for theft prevention when carrying cargo.
