Description

TECHNICAL FIELD

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

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

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

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

[0005] The base is used to support a child in a carrying state, and is used to form a barrier at the bottom in a carrying state.

[0006] The front barrier is used to form a barrier at the front of the multifunctional child seat for a two-wheeled vehicle (second type) in a carrying state. The front barrier is hinged to the base through a rotating shaft or a hinge, and the forward turning of the front barrier is limited by the rotating shaft or the hinge. The front barrier can be turned backward and placed on the base in a carrying state. It should be noted that the front barrier is hinged to the base by using a common hinge. By designing the position of the hinge center, the forward turning of the front barrier can be limited by the base. At this time, the hinge, together with a part of the front barrier and a part of the base, should be regarded as a rotating shaft with a limiting function, as shown in Figure 5 Figure 6 The hinge specifically refers to two or more components connected by a rotating pair at the same place, as shown in Figure 7 Figure 8 .

[0007] The folding mechanism comprises a first folding member, a folding locking member and a second folding member. The folding locking member is slidably arranged on the second folding member, or hingedly connected to the second folding member, or detachably connected to the second folding member. The first folding member is provided with a clamping groove. On the one hand, the clamping groove can cooperate with the folding locking member to one-way limit the folding mechanism in the object-carrying state, so that the multifunctional child seat of the two-wheeled vehicle cannot be converted from the object-carrying state to the person-carrying state. On the other hand, the clamping groove can also cooperate with the folding locking member to one-way limit the folding mechanism in the person-carrying state, so as to limit the maximum unfolding angle of the folding mechanism. It should be noted that when the folding locking member is slidably arranged on the second folding member, the self-locking of the folding mechanism can be realized by using gravity or friction. When the folding locking member is hingedly connected to the second folding member, the center of gravity of the folding locking member is designed, and the self-locking of the folding mechanism can be realized by using gravity. The folding locking member with threads can also be detachably connected to the second folding mechanism to realize the self-locking of the folding mechanism. The elastic element is not a necessary component of the folding mechanism.

[0008] The backrest comprises a first backrest member and a second backrest member. The first backrest member is fixed to the rear end of the base member. The second backrest member is hingedly connected to the first backrest member directly or indirectly through the folding mechanism. The maximum angle of the second backrest member forwardly turning around the hinge point is limited by the front wall member. When the second backrest member forwardly turns around the hinge point and is limited by the front wall member, the front wall member, the base member, the first backrest member and the second backrest member together form an enclosed structure. It should be noted that the second backrest member can be indirectly connected to the folding mechanism through the side wing member, or indirectly connected to the folding mechanism through other parts. The first backrest member can be indirectly connected to the folding mechanism through the side edge of the base, or indirectly connected to the folding mechanism through other parts.

[0009] The side wing member is fixed to the left and right sides of the second backrest member and turns with the second backrest member. In the object-carrying state, the side wing member is used to enclose the enclosed structure formed by the front wall member, the base member, the first backrest member and the second backrest member from the side, and the degree of enclosure can be partial or complete. In the person-carrying state, the side wing member fixed to the left and right sides of the second backrest member can protect the seated child from the side.

[0010] Further, in order to solve the problem that the forward turning of the second backrest member is not limited in the person-carrying state, which is not conducive to the installation and use of the safety belt, the above technical solution is improved: the folding locking member cooperates with the clamping groove to one-way limit the folding mechanism in the person-carrying state, thereby limiting the forward turning of the second backrest member, so that the multifunctional child seat of the two-wheeled vehicle (the second type) cannot be converted from the person-carrying state to the object-carrying state. The backrest limited in the forward turning in the person-carrying state is convenient for fixing the safety belt.

[0011] Further, in order to improve the comfort of the children and facilitate the movement of the arms of the children, the technical solution is improved by introducing a base side edge to reduce the area of the side wing and increase the movement range of the arms of the children. The base side edge is directly or indirectly fixed to the base and used to surround the seat together with the side wing. The base side edge can be directly fixed to the base, indirectly connected to the base through the first backrest, or connected to both the base and the first backrest. After introducing the base side edge, the side wing can be reduced by the corresponding area of the base side edge, thereby improving the movement range of the arms of the children. The base side edge can be connected to both the first backrest and the base to improve the structural strength of the seat.

[0012] Optionally, on the one hand, the long-term storage of the articles in the article-carrying state needs to consider the problem of theft prevention, and on the other hand, the folding mechanism of the folding locking piece needs to consider the problem of accidental unlocking. Therefore, a lock body and a lock piece are introduced to limit the displacement of the folding locking piece, which can serve as a security device to solve the problem of theft prevention and also solve the problem of accidental unlocking of the folding mechanism. The lock body is used to realize the locking function and is directly or indirectly fixed to the first backrest or directly or indirectly fixed to the second backrest, and the lock piece is connected to the lock body to limit the folding locking piece. The lock body can be indirectly fixed to the second backrest through the side wing, indirectly fixed to the first backrest through the base side edge, or indirectly fixed to the first backrest or the second backrest through other mechanisms. For example, the lock body is indirectly fixed to the second folding piece through a connecting piece and indirectly fixed to the second backrest through the second folding piece.

[0013] Further, the lock piece directly limits the folding locking piece, which limits the fixing point of the lock body. In order to provide a wider fixing point for the lock body, the technical solution is improved by introducing:

[0014] a rear pull rod indirectly connected to the folding locking piece to facilitate the limitation of the folding locking piece from a distance;

[0015] a front-rear connecting rod, which is a rigid piece, used to connect the folding locking piece and the rear pull rod;

[0016] a rear longitudinal connecting piece fixed to the folding mechanism, and the rear pull rod is slidably arranged in the rear longitudinal connecting piece.

[0017] According to another aspect of the present application, two multifunctional child seats for two-wheeled vehicles (second type) are provided, including a base, a front surrounding piece, a folding mechanism, a backrest, and a side wing.

[0018] The base is used to support the children in the passenger-carrying state and to form a surrounding for the bottom in the article-carrying state.

[0019] The front wall is used to form a wall for the front of the two-wheeled vehicle multifunctional child seat (second type) in the carrying state. The front wall is hinged to the base through a rotating shaft or a hinge. The forward turning of the front wall is limited by the rotating shaft or the hinge. The front wall can be turned backward and placed on the base in the carrying state. It should be noted that the front wall is hinged to the base by a common hinge. The position of the hinge center can limit the forward turning of the front wall by the base. At this time, the hinge, together with a part of the front wall and a part of the base, should be regarded as a rotating shaft with limiting function. The hinge specifically refers to two or more components connected by a rotating pair at the same place.

[0020] The folding mechanism includes a first folding piece, a folding locking piece, and a second folding piece. The folding locking piece is slidably arranged on the second folding piece, or hinged to the second folding piece, or detachably connected to the second folding piece. The first folding piece is provided with a clamping groove capable of cooperating with the folding locking piece to one-way limit the folding mechanism in the carrying state, so that the two-wheeled vehicle multifunctional child seat cannot be converted to the carrying state. One of the first folding piece and the second folding piece is provided with a positioning protrusion, and the other is provided with a positioning groove. The positioning protrusion and the positioning groove limit the maximum unfolding angle of the folding mechanism in the carrying state. It should be noted that when the folding locking piece is slidably arranged on the second folding piece, the self-locking of the folding mechanism can be realized by gravity or friction. When the folding locking piece is hinged to the second folding piece, the center of gravity of the folding locking piece is designed to realize the self-locking of the folding mechanism by gravity. The threaded folding locking piece can also be used to detachably connect the second folding mechanism to realize the self-locking of the folding mechanism. The elastic element is not a necessary component of the folding mechanism.

[0021] The backrest includes a first backrest piece and a second backrest piece. The first backrest piece is fixed to the rear end of the base. The second backrest piece is hinged to the first backrest piece directly or indirectly through the folding mechanism. The maximum angle of the forward turning of the second backrest piece around the hinge point is limited by the front wall. When the second backrest piece is turned forward around the hinge point and limited by the front wall, the front wall, the base, the first backrest piece, and the second backrest piece form a closed structure together. It should be noted that the second backrest piece can be indirectly connected to the folding mechanism through the side wing piece, or indirectly connected to the folding mechanism through other parts. The first backrest piece can be indirectly connected to the folding mechanism through the side edge of the base, or indirectly connected to the folding mechanism through other parts.

[0022] The side wings are fixed on the left and right sides of the second backrest and are turned over together with the second backrest. In the object-carrying state, the side wings are used to block the front wall, the base, the first backrest and the second backrest from the side, and the blocking degree can be partial or complete. In the human-carrying state, the side wings fixed on the left and right sides of the second backrest can protect the child from the side.

[0023] Further, in order to solve the problem that the second backrest is not limited in the forward turning state in the human-carrying state, which is not conducive to the installation and use of the safety belt, the above technical solution is improved: the folding locking member cooperates with the clamping groove to one-way limit the folding mechanism in the human-carrying state, thereby limiting the forward turning of the second backrest, so that the multifunctional child seat (second type) cannot be changed from the human-carrying state to the object-carrying state. The backrest limited in the forward turning state in the human-carrying state is convenient for fixing the safety belt.

[0024] Further, in order to improve the comfort of the child and facilitate the movement of the child's arms, the above technical solution is improved: the introduction of the base side edge reduces the area of the side wing and increases the movement range of the child's arms. The base side edge is directly or indirectly fixed to the base and is used to block the seat from the side together with the side wing. The base side edge can be directly fixed to the base, indirectly connected to the base through the first backrest, or connected to both the base and the first backrest. After the introduction of the base side edge, the side wing can subtract the corresponding area of the base side edge to improve the movement range of the child's arms. The base side edge can be connected to both the first backrest and the base to improve the structural strength of the seat.

[0025] Optionally, on the one hand, in the object-carrying state, the long-term storage of the article needs to consider the problem of theft prevention, and on the other hand, in the human-carrying state, the folding mechanism needs to consider the problem of accidental unlocking of the folding locking member. Therefore, the lock body and the lock piece are introduced to limit the displacement of the folding locking member, which can serve as a security device to solve the problem of theft prevention and also solve the problem of accidental unlocking of the folding mechanism. The lock body is used to realize the locking function and is directly or indirectly fixed to the first backrest or directly or indirectly fixed to the second backrest, and the lock piece is connected to the lock body to limit the folding locking member. The lock body can be indirectly fixed to the second backrest through the side wing, indirectly fixed to the first backrest through the base side edge, or indirectly fixed to the first backrest or the second backrest through other mechanisms. For example, the lock body is indirectly fixed to the second folding member through a connecting member, and is indirectly fixed to the second backrest through the second folding member.

[0026] Furthermore, the direct limitation of the folding locking element on the lock plate restricts the fixed points of the lock body. To provide the lock body with a wider range of fixed points, the above technical solution is improved by introducing:

[0027] The rear pull rod is indirectly connected to the folding locking mechanism, making it easy to limit the folding locking mechanism from a distance;

[0028] The front and rear linkages are rigid components used to connect the folding locking mechanism and the rear pull rod;

[0029] The rear longitudinal connector is fixed to the folding mechanism, and the rear tie rod is slidably mounted on the rear longitudinal connector. Attached Figure Description

[0063] 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, and are unrelated to the left-right direction of the accompanying drawings. For the sake of brevity, the multi-functional child seat for a two-wheeled vehicle provided in the following embodiments can be simply referred to as a "seat."

[0064] 1. A first embodiment of a multi-functional child seat for a two-wheeled vehicle (Type II).

[0065] like Figure 1 and Figure 2 As shown, this embodiment provides a multi-functional child seat for a two-wheeled vehicle, including: a base component 1, a front panel component 2, a folding mechanism 3, a backrest 4, and side wings 5.

[0066] The base component 1 is used to support a child when in passenger mode and to form a barrier around the bottom when in cargo mode.

[0067] The front barrier 2 is hinged to the front end of the base 1 via a pivot 21. In cargo-carrying mode, the front barrier 2 blocks the front of the seat; in passenger-carrying mode, it can be flipped backward onto the base 1. The pivot 21 limits the maximum angle at which the front barrier 2 can flip forward.

[0068] The folding mechanism 3 includes a first folding member 31, a folding locking member 33, and a second folding member 32. The folding locking member 33 is slidably disposed on the second folding member 32, and its sliding direction is horizontal sliding left and right. The first folding member 31 is provided with a slot 34. On the one hand, the slot 34 can cooperate with the folding locking member 33 to unidirectionally limit the folding mechanism 3 when in the cargo-carrying state, so that the two-wheeled vehicle's multi-functional child seat cannot be converted to the passenger-carrying state. On the other hand, the slot 34 can also cooperate with the folding locking member 33 to unidirectionally limit the folding mechanism 3 when in the passenger-carrying state, limiting the maximum unfolding angle of the folding mechanism 3.

[0069] The backrest 4 includes a first backrest component 41 and a second backrest component 42. The first backrest component 41 is fixed to the rear end of the base component 1. The second backrest component 42 is directly hinged to the first backrest component 41 through the folding mechanism 3. The maximum angle at which the second backrest component 42 and the first folding mechanism 31 flip forward around the hinge point is limited by the front baffle component 2. When the second backrest component 42 flips forward around the hinge point and is limited by the front baffle component 2, the front baffle component 2, the base component 1, the first backrest component 41, and the second backrest component 42 together form an enclosing structure.

[0070] Side wings 5 ​​are fixed to the left and right sides of the second backrest 42 and flip together with the second backrest 42. In the cargo-carrying mode, the side wings 5 ​​are used to enclose the enclosure structure formed by the front barrier 2, the base 1, the first backrest 41, and the second backrest 42 from the side. In the passenger-carrying mode, the side wings 5 ​​can protect the riding toddler from the side.

[0071] In this embodiment, the base component 1 and the first backrest component 41 are two parts integrally formed from the same material. Similarly, the side wing component 5 and the second backrest component 42 are two parts integrally formed from the same material. The first folding component 31 and the second backrest component 42 are also two parts integrally formed from the same material.

[0072] This embodiment has two usage states, and the specific switching process is as follows: In the passenger-carrying usage state, the front barrier 2 is flipped forward until it is limited by the pivot 21. The folding locking member 33 is pulled laterally to release the limitation on the folding mechanism 3. The second backrest member 42 is pushed forward to flip until it is limited by the front barrier 2. The folding locking member 33 is pushed to insert into the slot 34, thereby limiting the folding mechanism 3 and limiting the rearward flipping of the second backrest member 42. After completing the state switching, the specific structure after entering the cargo-carrying usage state is as follows: Figure 2 As shown.

[0073] Furthermore, in the passenger-carrying mode, the folding locking member 33 and the slot 3 of this embodiment can cooperate with each other to limit the folding mechanism 3 and limit the forward flipping of the second backrest member 42, so that the two-wheeled vehicle multi-functional child seat cannot be switched from the passenger-carrying mode to the cargo-carrying mode.

[0074] 2. A second embodiment of a multi-functional child seat for a two-wheeled vehicle (Type II).

[0075] like Figure 3 and Figure 4 As shown, this embodiment provides a multi-functional child seat for a two-wheeled vehicle, including: a base component 1, a front panel component 2, a folding mechanism 3, a backrest 4, and side wings 5.

[0076] The base component 1 is used to support a child when in passenger mode and to form a barrier around the bottom when in cargo mode.

[0077] The front barrier 2 is hinged to the front end of the base 1 via a pivot 21. In cargo-carrying mode, the front barrier 2 blocks the front of the seat; in passenger-carrying mode, it can be flipped backward onto the base 1. The pivot 21 limits the maximum angle at which the front barrier 2 can flip forward.

[0078] The folding mechanism 3 includes a first folding member 31, a folding locking member 33, and a second folding member 32. The folding locking member 33 is slidably disposed on the second folding member 32, and its sliding direction is vertical in the loading and use state. The first folding member 31 is provided with a slot 34. On the one hand, the slot 34 can cooperate with the folding locking member 33 to unidirectionally limit the folding mechanism 3 in the loading and use state, so that the two-wheeled vehicle multi-functional child seat cannot be transformed into the passenger-carrying state. On the other hand, the slot 34 can also cooperate with the folding locking member 33 to unidirectionally limit the folding mechanism 3 in the passenger-carrying state, limiting the maximum unfolding angle of the folding mechanism 3.

[0079] The backrest 4 includes a first backrest component 41 and a second backrest component 42. The first backrest component 41 is fixed to the rear end of the base component 1. The second backrest component 42 is directly hinged to the first backrest component 41 through the folding mechanism 3. The maximum angle at which the second backrest component 42 and the first folding mechanism 31 flip forward around the hinge point is limited by the front baffle component 2. When the second backrest component 42 flips forward around the hinge point and is limited by the front baffle component 2, the front baffle component 2, the base component 1, the first backrest component 41, and the second backrest component 42 together form an enclosing structure.

[0080] Side wings 5 ​​are fixed to the left and right sides of the second backrest 42 and flip together with the second backrest 42. In the cargo-carrying mode, the side wings 5 ​​are used to enclose the enclosure structure formed by the front barrier 2, the base 1, the first backrest 41, and the second backrest 42 from the side. In the passenger-carrying mode, the side wings 5 ​​can protect the riding toddler from the side.

[0081] In this embodiment, the base component 1, the first backrest component 41, the side wing component 5, the second backrest component 42, the first folding component 31, the second backrest component 42, the second folding component 32, and the first backrest component 41 are all integrally formed from the same material. In this embodiment, the base component 1 and the front baffle component 2 are hinged together by a pivot 21, which is integrally formed. When the front baffle component 2 is flipped forward to its maximum angle, the portion of the pivot 21 that connects to the front baffle component 2 is limited by the base component 1.

[0082] This embodiment has two usage states, and the specific switching process is as follows: In the passenger-carrying usage state, push the folding locking member 33 to disengage it from the slot 34 to release the restriction on the folding mechanism 3, and push the second backrest member 42 to flip forward until it is restricted by the front blocking member 2. Push the folding locking member 33 to insert it into the slot 34, thereby restricting the folding mechanism 3 and the rearward flipping of the second backrest member 42. After completing the state switching, the specific structure after entering the cargo-carrying usage state is as follows. Figure 4 As shown.

[0083] Furthermore, in the passenger-carrying mode, the folding locking member 33 and the slot 3 of this embodiment can cooperate with each other to limit the folding mechanism 3 and limit the forward flipping of the second backrest member 42, so that the two-wheeled vehicle multi-functional child seat cannot be switched from the passenger-carrying mode to the cargo-carrying mode.

[0084] Furthermore, the two-wheeled multi-functional child seat of this embodiment also includes: a base side 14. The base side 14 is fixed to the base member 1 and is used together with the side wing member 5 to side-enclose the seat, thereby reducing the area of ​​the side wing member 5 and increasing the range of motion of the child's arms.

[0085] 3. A third embodiment of a multi-functional child seat for a two-wheeled vehicle (Type II).

[0086] like Figure 5 and Figure 6 As shown, this embodiment provides a multi-functional child seat for a two-wheeled vehicle, including: a base component 1, a front panel component 2, a folding mechanism 3, a backrest 4, and side wings 5.

[0087] The base component 1 supports the child in passenger mode and forms a barrier around the bottom in cargo mode. The front barrier component 2 is hinged to the front end of the base component 1 via a pivot 21. In cargo mode, the front barrier component 2 blocks the front of the seat; in passenger mode, it can be flipped backward onto the base component. The pivot 21 limits the maximum forward flip angle of the front barrier component 2. The folding mechanism 3 includes a first folding component 31, a folding locking component 33, and a second folding component 32. The folding locking component 33 is hinged to the second folding component 32. The first folding component 31 has a slot 34. This slot 34 cooperates with the folding locking component 33 to unidirectionally limit the folding mechanism 3 in cargo mode, preventing the two-wheeled multi-functional child seat from transitioning to passenger mode. It also cooperates with the folding locking component 33 to unidirectionally limit the folding mechanism 3 in passenger mode, restricting its maximum unfolding angle.

[0088] The backrest 4 comprises a first backrest component 41 and a second backrest component 42. The first backrest component 41 is fixed to the rear end of the base component 1. The second backrest component 42 is directly hinged to the first backrest component 41 via a folding mechanism 3. The maximum forward rotation angle of the second backrest component 42 and the first folding mechanism 31 around the hinge point is limited by the front baffle component 2. When the second backrest component 42 rotates forward around the hinge point and is limited by the front baffle component 2, the front baffle component 2, the base component 1, the first backrest component 41, and the second backrest component 42 together form an enclosing structure. The side wings 5 ​​are fixed to the left and right sides of the second backrest component 42 and rotate together with the second backrest component 42. In the cargo-carrying state, the side wings 5 ​​are used to enclose the enclosing structure formed by the front baffle component 2, the base component 1, the first backrest component 41, and the second backrest component 42 from the side. In the passenger-carrying state, the side wings 5 ​​can protect the riding toddler from the side.

[0089] This embodiment has two usage states, and the specific switching process is as follows: In the passenger-carrying usage state, push the folding locking member 33 from the rear of the first backrest member 41 to disengage it from the slot 34, thereby releasing the restriction on the folding mechanism 3. Push the front baffle member 2 to flip forward to its maximum angle, and push the second backrest member 42 to flip forward until it is restricted by the front baffle member 2. Push the folding locking member 33 to insert it into the slot 34, thereby restricting the folding mechanism 3 and the rearward flipping of the second backrest member 42. After completing the state switching, the specific structure after entering the cargo-carrying usage state is as follows: Figure 6 As shown.

[0090] Furthermore, in the passenger-carrying mode, the folding locking member 33 and the slot 3 of this embodiment can cooperate with each other to limit the folding mechanism 3 and limit the forward flipping of the second backrest member 42, so that the two-wheeled vehicle multi-functional child seat cannot be switched from the passenger-carrying mode to the cargo-carrying mode.

[0091] Furthermore, the two-wheeled multi-functional child seat of this embodiment also includes: a base side 14. The base side 14 is fixed to the base member 1 and is used together with the side wing member 5 to side-enclose the seat, thereby reducing the area of ​​the side wing member 5 and increasing the range of motion of the child's arms.

[0092] In this embodiment, the folding locking member 33 is hinged to the second folding member 32. The mass distribution of the folding locking member 33 on both sides of the hinge point is different, allowing it to maintain its position under the action of gravity and remain embedded in the slot 34. In this embodiment, the base member 1, the first backrest member 41, the base side 14, and the second folding member 32 are four parts integrally formed from the same material. In this embodiment, there are two of each of the first folding member 31, the second folding member 32, and the folding locking member.

[0093] 4. A fourth embodiment of a multi-functional child seat for a two-wheeled vehicle (Type II).

[0094] likeFigure 7 and Figure 8 As shown, this embodiment provides a multi-functional child seat for a two-wheeled vehicle, including: a base component 1, a front panel component 2, a folding mechanism 3, a backrest 4, and side wings 5.

[0095] The base component 1 supports a child in passenger mode and forms a barrier around the bottom in cargo mode. The front barrier component 2 is hinged to the front end of the base component 1 via a hinge 22. In cargo mode, the front barrier component 2 blocks the front of the seat; in passenger mode, it can be flipped backward onto the base component. The hinge 22 limits the maximum angle at which the front barrier component 2 can be flipped forward.

[0096] The folding mechanism 3 includes a first folding member 31, a folding locking member 33, and a second folding member 32. The folding locking member 33 is a bolt and is detachably connected to the second folding member 32. Rotating the folding locking member 33 can adjust its depth into the slot 34. The first folding member 31 is provided with a slot 34. On the one hand, the slot 34 can cooperate with the folding locking member 33 to unidirectionally limit the folding mechanism 3 when in the cargo-carrying state, preventing the two-wheeled vehicle's multi-functional child seat from being converted to a passenger-carrying state. On the other hand, the slot 34 can also cooperate with the folding locking member 33 to unidirectionally limit the folding mechanism 3 when in the passenger-carrying state, limiting the maximum unfolding angle of the folding mechanism 3.

[0097] The backrest 4 comprises a first backrest component 41 and a second backrest component 42. The first backrest component 41 is fixed to the rear end of the base component 1. The second backrest component 42 is directly hinged to the first backrest component 41 via a folding mechanism 3. The maximum angle at which the second backrest component 42 and the folding mechanism 32 rotate forward around the hinge point is limited by the front baffle component 2. When the second backrest component 42 rotates forward around the hinge point and is limited by the front baffle component 2, the front baffle component 2, the base component 1, the first backrest component 41, and the second backrest component 42 together form an enclosing structure. The side wings 5 ​​are fixed to the left and right sides of the second backrest component 42 and rotate together with the second backrest component 42. In the cargo-carrying state, the side wings 5 ​​are used to enclose the enclosing structure formed by the front baffle component 2, the base component 1, the first backrest component 41, and the second backrest component 42 from the side. In the passenger-carrying state, the side wings 5 ​​can protect the riding toddler from the side.

[0098] In this embodiment, the base component 1, the first folding component 31, and the first backrest component 41 are three parts integrally formed from the same material. In this embodiment, the folding locking component 33 is detachably connected to the second folding component 32. After leaving the slot 34, the folding locking component 33 is still connected to the second folding component 32. At this time, the folding locking component 33 moves together with the second backrest component 42.

[0099] This embodiment has two usage states, and the specific switching process is as follows: In the passenger-carrying usage state, rotate the folding locking member 33 to disengage it from the slot 34, thereby releasing the restriction on the folding mechanism 3. Flip the front baffle 2 forward to its maximum angle, pushing the second backrest 42 forward until it is restricted by the front baffle 2. Rotate the folding locking member 33 in the opposite direction to insert it into the slot 34, thereby restricting the folding mechanism 3 and the backward flipping of the second backrest 42. After completing the state switch, the specific structure after entering the cargo-carrying usage state is as follows: Figure 8 As shown.

[0100] Furthermore, in the passenger-carrying mode, the folding locking member 33 and the slot 3 of this embodiment can cooperate with each other to limit the folding mechanism 3 and limit the forward flipping of the second backrest member 42, so that the two-wheeled vehicle multi-functional child seat cannot be switched from the passenger-carrying mode to the cargo-carrying mode.

[0101] Furthermore, the two-wheeled multi-functional child seat of this embodiment also includes: a base side 14. The base side 14 is fixed to the base member 1 and is used together with the side wing member 5 to side-enclose the seat, thereby reducing the area of ​​the side wing member 5 and increasing the range of motion of the child's arms.

[0102] 5. A fifth embodiment of a multi-functional child seat for a two-wheeled vehicle (Type II).

[0103] like Figure 9 , Figure 10 as well as Figure 11 As shown, this embodiment provides a multi-functional child seat for a two-wheeled vehicle, including: a base component 1, a front panel component 2, a folding mechanism 3, a backrest 4, and side wings 5.

[0104] The base component 1 supports a child in passenger mode and forms a barrier around the bottom in cargo mode. The front barrier component 2 is hinged to the front end of the base component 1 via a hinge 22. In cargo mode, the front barrier component 2 blocks the front of the seat; in passenger mode, it can be flipped backward onto the base component. The hinge 22 limits the maximum angle at which the front barrier component 2 can be flipped forward.

[0105] The folding mechanism 3 includes a first folding member 31, a folding locking member 33, and a second folding member 32. The folding locking member 33 slides on the second folding member 32, and its movement direction is up and down when in passenger use. The first folding member 31 is provided with a slot 34. On the one hand, the slot 34 can cooperate with the folding locking member 33 to unidirectionally limit the folding mechanism 3 when in passenger use, preventing the two-wheeled vehicle's multi-functional child seat from changing to passenger use. On the other hand, the slot 34 can also cooperate with the folding locking member 33 to unidirectionally limit the folding mechanism 3 when in passenger use, restricting the maximum unfolding angle of the folding mechanism 3.

[0106] The backrest 4 comprises a first backrest component 41 and a second backrest component 42. The first backrest component 41 is fixed to the rear end of the base component 1. The second backrest component 42 is directly hinged to the first backrest component 41 via a folding mechanism 3. The maximum angle at which the second backrest component 42 and the folding mechanism 32 rotate forward around the hinge point is limited by the front baffle component 2. When the second backrest component 42 rotates forward around the hinge point and is limited by the front baffle component 2, the front baffle component 2, the base component 1, the first backrest component 41, and the second backrest component 42 together form an enclosing structure. The side wings 5 ​​are fixed to the left and right sides of the second backrest component 42 and rotate together with the second backrest component 42. In the cargo-carrying state, the side wings 5 ​​are used to enclose the enclosing structure formed by the front baffle component 2, the base component 1, the first backrest component 41, and the second backrest component 42 from the side. In the passenger-carrying state, the side wings 5 ​​can protect the riding toddler from the side.

[0107] Furthermore, in the passenger-carrying mode, the folding locking member 33 and the slot 34 of this embodiment can cooperate with each other to limit the forward flipping of the second backrest member 42 through the limiting folding mechanism 3, so that the two-wheeled vehicle multi-functional child seat cannot be switched from the passenger-carrying mode to the cargo-carrying mode.

[0108] Furthermore, the two-wheeled multi-functional child seat of this embodiment also includes: a base side 14. The base side 14 is fixed to the base member 1 and is used together with the side wing member 5 to side-enclose the seat, thereby reducing the area of ​​the side wing member 5 and increasing the range of motion of the child's arms.

[0109] In this embodiment, the folding locking member slides onto the second folding member 32, and its two ends slide onto the second backrest member 42. The second folding member 32 is fixed to the second backrest member 42, and under the influence of gravity, the folding locking member 33 maintains its position and remains embedded in the slot 34. In this embodiment, there are two first folding members 31 and two second folding members 32. In this embodiment, the base side 14, the base member 1, and the first backrest member 41 are three parts integrally formed from the same material.

[0110] 6. A sixth embodiment of a multi-functional child seat for a two-wheeled vehicle (Type II)

[0111] like Figure 12 , Figure 13 and Figure 14 As shown, this embodiment provides a multi-functional child seat for a two-wheeled vehicle, including: a base component 1, a front panel component 2, a folding mechanism 3, a backrest 4, and side wings 5.

[0112] The base component 1 supports a child in passenger mode and forms a barrier around the bottom in cargo mode. The front barrier component 2 is hinged to the front end of the base component 1 via a pivot 21. In cargo mode, the front barrier component 2 blocks the front of the seat; in passenger mode, it can be flipped backward onto the base component. The pivot 21 limits the maximum angle at which the front barrier component 2 can flip forward.

[0113] The folding mechanism 3 includes a first folding member 31, a folding locking member 33, and a second folding member 32. The folding locking member 33 is laterally slidable on the second folding member 32, and its transverse cross-section is rectangular. The first folding member 31 is provided with a slot 34. On the one hand, the slot 34 can cooperate with the folding locking member 33 to unidirectionally limit the folding mechanism 3 in the cargo-carrying state, preventing the two-wheeled vehicle's multi-functional child seat from being converted to a passenger-carrying state. On the other hand, the slot 34 can also cooperate with the folding locking member 33 to unidirectionally limit the folding mechanism 3 in the passenger-carrying state, restricting the maximum unfolding angle of the folding mechanism 3.

[0114] The backrest 4 comprises a first backrest component 41 and a second backrest component 42. The first backrest component 41 is fixed to the rear end of the base component 1. The second backrest component 42 is directly hinged to the first backrest component 41 via a folding mechanism 3. The maximum angle at which the second backrest component 42 and the folding mechanism 32 rotate forward around the hinge point is limited by the front baffle component 2. When the second backrest component 42 rotates forward around the hinge point and is limited by the front baffle component 2, the front baffle component 2, the base component 1, the first backrest component 41, and the second backrest component 42 together form an enclosing structure. The side wings 5 ​​are fixed to the left and right sides of the second backrest component 42 and rotate together with the second backrest component 42. In the cargo-carrying state, the side wings 5 ​​are used to enclose the enclosing structure formed by the front baffle component 2, the base component 1, the first backrest component 41, and the second backrest component 42 from the side. In the passenger-carrying state, the side wings 5 ​​can protect the riding toddler from the side.

[0115] Furthermore, in the passenger-carrying mode, the folding locking member 33 and the slot 3 of this embodiment can cooperate with each other to limit the folding mechanism 3 and limit the forward flipping of the second backrest member 42, so that the two-wheeled vehicle multi-functional child seat cannot be switched from the passenger-carrying mode to the cargo-carrying mode.

[0116] Furthermore, the two-wheeled multi-functional child seat of this embodiment also includes: a lock body 91 and a lock plate 92. The lock body 91 is fixed to the second backrest 42 via the side wing 5, and the lock plate 92 is fixed to the lock body 91. Operating the lock body 91 causes the lock plate 92 to rotate, which can limit the lateral movement of the flip-up locking member 33.

[0117] In this embodiment, the folding locking member is laterally slidably disposed on the second folding member 32. The second folding member 32 and the first backrest member 41 are two parts integrally formed from the same material. Under the action of friction, the folding locking member 33 can maintain its position and always be embedded in the slot 34. In this embodiment, there is one first folding member 31 and one second folding member 32.

[0120] The base component 1 supports a child in passenger mode and forms a barrier around the bottom in cargo mode. The front barrier component 2 is hinged to the front end of the base component 1 via a pivot 21. In cargo mode, the front barrier component 2 blocks the front of the seat; in passenger mode, it can be flipped backward onto the base component. The pivot 21 limits the maximum angle at which the front barrier component 2 can flip forward.

[0121] The folding mechanism 3 includes a first folding member 31, a folding locking member 33, and a second folding member 32; the folding locking member 33 is hinged to the second folding member 32. The first folding member 31 is provided with a slot 34. On the one hand, the slot 34 can cooperate with the folding locking member 33 to unidirectionally limit the folding mechanism 3 in the cargo-carrying state, preventing the two-wheeled vehicle's multi-functional child seat from being converted to a passenger-carrying state. On the other hand, the slot 34 can also cooperate with the folding locking member 33 to unidirectionally limit the folding mechanism 3 in the passenger-carrying state, restricting the maximum unfolding angle of the folding mechanism 3.

[0122] The backrest 4 comprises a first backrest component 41 and a second backrest component 42. The first backrest component 41 is fixed to the rear end of the base component 1. The second backrest component 42 is directly hinged to the first backrest component 41 via a folding mechanism 3. The maximum angle at which the second backrest component 42 and the folding mechanism 32 rotate forward around the hinge point is limited by the front baffle component 2. When the second backrest component 42 rotates forward around the hinge point and is limited by the front baffle component 2, the front baffle component 2, the base component 1, the first backrest component 41, and the second backrest component 42 together form an enclosing structure. The side wings 5 ​​are fixed to the left and right sides of the second backrest component 42 and rotate together with the second backrest component 42. In the cargo-carrying state, the side wings 5 ​​are used to enclose the enclosing structure formed by the front baffle component 2, the base component 1, the first backrest component 41, and the second backrest component 42 from the side. In the passenger-carrying state, the side wings 5 ​​can protect the riding toddler from the side.

[0123] Furthermore, in the passenger-carrying mode, the folding locking member 33 and the slot 34 of this embodiment can cooperate with each other to limit the folding mechanism 3 and limit the forward flipping of the second backrest member 42, so that the two-wheeled vehicle multi-functional child seat cannot be switched from the passenger-carrying mode to the cargo-carrying mode.

[0124] Furthermore, the two-wheeled multi-functional child seat of this embodiment also includes: a lock body 91 and a lock plate 92. The lock body 91 is fixed to the second backrest 42 via the side wing 5, and the lock plate 92 is fixed to the lock body 91. Operating the lock body 91 causes the lock plate 92 to rotate, thereby limiting the folding locking member 33.

[0125] In this embodiment, the lock body 91 is fixed to the first backrest member 41, and the lock plate 91 is used to directly limit the folding locking member 33 that is hinged to the second folding member 32. In this embodiment, the base member 1, the first backrest member 41, and the second folding member 42 are three parts integrally formed from the same material. In this embodiment, there are two of each of the first folding member 31, the second folding member 32, and the folding locking member 33.

[0128] The base component 1 supports a child in passenger mode and forms a barrier around the bottom in cargo mode. The front barrier component 2 is hinged to the front end of the base component 1 via a pivot 21. In cargo mode, the front barrier component 2 blocks the front of the seat; in passenger mode, it can be flipped backward onto the base component. The pivot 21 limits the maximum angle at which the front barrier component 2 can flip forward.

[0129] The folding mechanism 3 includes a first folding member 31, a folding locking member 33, and a second folding member 32. The folding locking member 33 is a bolt that is detachably connected to the second folding member 32. The first folding member 31 is provided with a slot 34. On the one hand, the slot 34 can cooperate with the folding locking member 33 to unidirectionally limit the folding mechanism 3 when in the cargo-carrying state, preventing the two-wheeled vehicle's multi-functional child seat from being converted to a passenger-carrying state.

[0130] The backrest 4 comprises a first backrest component 41 and a second backrest component 42. The first backrest component 41 is fixed to the rear end of the base component 1. The second backrest component 42 is directly hinged to the first backrest component 41 via a folding mechanism 3.

When the second backrest component 42 rotates forward around the hinge point and is limited by the front baffle component 2, the front baffle component 2, the base component 1, the first backrest component 41, and the second backrest component 42 together form an enclosing structure. The side wings 5 ​​are fixed to the left and right sides of the second backrest component 42 and rotate together with the second backrest component 42. In the cargo-carrying state, the side wings 5 ​​are used to enclose the enclosing structure formed by the front baffle component 2, the base component 1, the first backrest component 41, and the second backrest component 42 from the side. In the passenger-carrying state, the side wings 5 ​​can protect the riding toddler from the side.

[0131] Furthermore, in the passenger-carrying mode, the folding locking member 33 and the slot 34 of this embodiment can cooperate with each other to limit the folding mechanism 3 and limit the forward flipping of the second backrest member 42, so that the two-wheeled vehicle multi-functional child seat cannot be switched from the passenger-carrying mode to the cargo-carrying mode.

[0132] Furthermore, the two-wheeled multi-functional child seat of this embodiment also includes: a lock body 91 and a lock plate 92. The lock body 91 is fixed to the second backrest 42 via the side wing 5, and the lock plate 92 is fixed to the lock body 91. Operating the lock body 91 causes the lock plate 92 to rotate, thereby limiting the folding locking member 33.

[0133] In this embodiment, the lock body 91 is indirectly fixed to the first backrest member 41 via the side wing member 5. The lock plate 91 is used to directly limit the folding locking member 33, restricting the folding locking member 33 from lateral displacement by rotation, thus preventing the folding locking member 33 from leaving the slot 34. In this embodiment, there are two of each of the first folding member 31, the second folding member 32, and the folding locking member 33. In this embodiment, the second folding member 32 and the side wing member 5 are two parts integrally formed from the same material.

In cargo mode, the front barrier component 2 blocks the front of the seat; in passenger mode, it can be flipped backward onto the base component. The pivot 21 limits the maximum angle at which the front barrier component 2 can flip forward.

[0137] The folding mechanism 3 includes a first folding member 31, a folding locking member 33, and a second folding member 32. The folding locking member 33 is laterally slidable on the second folding member 32. The first folding member 31 is provided with a slot 34.

The second backrest component 42 is directly hinged to the first backrest component 41 via a folding mechanism 3. The maximum angle at which the second backrest component 42 and the folding mechanism 32 rotate forward around the hinge point is limited by the front baffle component 2. When the second backrest component 42 rotates forward around the hinge point and is limited by the front baffle component 2, the front baffle component 2, the base component 1, the first backrest component 41, and the second backrest component 42 together form an enclosing structure. The side wings 5 ​​are fixed to the left and right sides of the second backrest component 42 and rotate together with the second backrest component 42. In the cargo-carrying state, the side wings 5 ​​are used to enclose the enclosing structure formed by the front baffle component 2, the base component 1, the first backrest component 41, and the second backrest component 42 from the side. In the passenger-carrying state, the side wings 5 ​​can protect the riding toddler from the side.

[0139] Furthermore, in the passenger-carrying mode, the folding locking member 33 and the slot 34 of this embodiment can cooperate with each other to limit the folding mechanism 3 and limit the forward flipping of the second backrest member 42, so that the two-wheeled vehicle multi-functional child seat cannot be switched from the passenger-carrying mode to the cargo-carrying mode.

The lock body 91 is fixed to the second backrest 42 via the side wing 5, and the lock plate 92 is fixed to the lock body 91. Operating the lock body 91 causes the lock plate 92 to rotate, thereby limiting the folding locking member 33.

[0141] Furthermore, the two-wheeled vehicle multi-functional child seat of this embodiment also includes: a rear pull rod 37, which is indirectly connected to the folding locking member 33, so as to limit the folding locking member 33 from a distance; a front and rear connecting rod 38, which is a rigid member, used to connect the folding locking member 33 and the rear pull rod 37; and a rear longitudinal connecting member 39, which is fixed to the folding mechanism 3, and the rear pull rod slides 37 on the rear longitudinal connecting member 39.

In this embodiment, the lock body 91 is fixed to the first backrest member 41. The movement of the locking plate 92 is driven by the lock body 91, and the locking plate 92 indirectly limits the lateral movement of the folding locking member 33 through the limiting front and rear connecting rods 38. In this embodiment, one end of the front and rear connecting rods 38 is fixed to the folding locking member 33, and the other end is fixed to the rear pull rod 37.

[0145] The base component 1 supports a child in passenger mode and forms a barrier around the bottom in cargo mode. The front barrier component 2 is hinged to the front end of the base component 1 via a pivot 21. In cargo mode, the front barrier component 2 blocks the front of the seat; in passenger mode, it can be flipped backward onto the base component. The pivot 21 limits the maximum angle at which the front barrier component 2 can be flipped forward.

[0146] The folding mechanism 3 includes a first folding member 31, a folding locking member 33, and a second folding member 32. The folding locking member 33 is hinged to the second folding member 32. The first folding member 31 is provided with a slot 34.

On the other hand, the slot 34 can also cooperate with the folding locking member 33 to unidirectionally limit the folding mechanism 3 when in the passenger-carrying state, restricting the maximum unfolding angle of the folding mechanism 3.

[0147] The backrest 4 comprises a first backrest component 41 and a second backrest component 42. The first backrest component 41 is fixed to the rear end of the base component 1. The second backrest component 42 is directly hinged to the first backrest component 41 via a folding mechanism 3. The maximum angle at which the second backrest component 42 and the folding mechanism 32 rotate forward around the hinge point is limited by the front baffle component 2. When the second backrest component 42 rotates forward around the hinge point and is limited by the front baffle component 2, the front baffle component 2, the base component 1, the first backrest component 41, and the second backrest component 42 together form an enclosing structure. The side wings 5 ​​are fixed to the left and right sides of the second backrest component 42 and rotate together with the second backrest component 42. In the cargo-carrying state, the side wings 5 ​​are used to enclose the enclosing structure formed by the front baffle component 2, the base component 1, the first backrest component 41, and the second backrest component 42 from the side. In the passenger-carrying state, the side wings 5 ​​can protect the riding toddler from the side.

[0148] Furthermore, in the passenger-carrying mode, the folding locking member 33 and the slot 34 of this embodiment can cooperate with each other to limit the folding mechanism 3 and limit the forward flipping of the second backrest member 42, so that the two-wheeled vehicle multi-functional child seat cannot be switched from the passenger-carrying mode to the cargo-carrying mode.

[0149] Furthermore, the two-wheeled multi-functional child seat of this embodiment also includes: a lock body 91 and a lock plate 92. The lock body 91 is fixed to the second backrest 42 via the side wing 5, and the lock plate 92 is fixed to the lock body 91. Operating the lock body 91 causes the lock plate 92 to rotate, thereby limiting the folding locking member 33.

[0150] Furthermore, the two-wheeled vehicle multi-functional child seat of this embodiment also includes: a rear pull rod 37, which is indirectly connected to the folding locking member 33, so as to limit the folding locking member 33 from a distance; a front and rear connecting rod 38, which is a rigid member, used to connect the folding locking member 33 and the rear pull rod 37; and a rear longitudinal connecting member 39, which is fixed to the folding mechanism 3, and the rear pull rod slides 37 on the rear longitudinal connecting member 39.

[0151] This embodiment also includes a base side 14, which is fixed to the base component 1. In this embodiment, the lock body 91 is fixed to the first backrest component 41. The lock plate 92 is driven by the lock body 91 to move up and down via the limiting pull rod 37, thereby indirectly limiting the folding locking component 33. In this embodiment, one end of the front and rear connecting rod 38 is hinged to the folding locking component 33, and the other end is connected to the pull rod 37. In this embodiment, the folding locking component 33 is hinged to the second folding component 32. The second folding component 32 and the rear longitudinal connecting component 39 are two parts integrally formed from the same material. The first folding component 31 and the second backrest component 42 are two parts integrally formed from the same material. Under the action of gravity, the folding locking component 33 can maintain its position and always be embedded in the slot 34. In this embodiment, there are two of each of the first folding component 31, the second folding component 32, the folding locking component 33, and the front and rear connecting rods 38.

[0154] The base component 1 supports a child in passenger mode and forms a barrier around the bottom in cargo mode. The front barrier component 2 is hinged to the front end of the base component 1 via a pivot 21. In cargo mode, the front barrier component 2 blocks the front of the seat; in passenger mode, it can be flipped backward onto the base component. The pivot 21 limits the maximum angle at which the front barrier component 2 can be flipped forward.

[0155] The folding mechanism 3 includes a first folding member 31, a folding locking member 33, and a second folding member 32. The folding locking member 33 is slidably mounted on the second folding member 32, and its sliding direction is lateral sliding. The first folding member 31 is provided with a slot 34, which can cooperate with the folding locking member 33 to unidirectionally limit the folding mechanism 3 in the cargo-carrying state, preventing the two-wheeled vehicle's multi-functional child seat from being converted to a passenger-carrying state. The first folding member 31 is provided with a positioning protrusion 35, and the second folding member 32 is provided with a positioning groove 36. The positioning protrusion 35 and the positioning groove 36 limit the maximum unfolding angle of the folding mechanism 3 in the passenger-carrying state.

[0156] The backrest 4 includes a first backrest component 41 and a second backrest component 42. The first backrest component 41 is fixed to the rear end of the base component 1. The second backrest component 42 is directly hinged to the first backrest component 41 via a folding mechanism 3. The maximum angle at which the second backrest component 42 and the first folding mechanism 31 rotate forward around the hinge point is limited by the front baffle component 2. When the second backrest component 42 rotates forward around the hinge point and is limited by the front baffle component 2, the front baffle component 2, the base component 1, the first backrest component 41, and the second backrest component 42 together form an enclosing structure. The side wings 5 ​​are fixed to the left and right sides of the second backrest component 42 and rotate together with the second backrest component 42. In the cargo-carrying state, the side wings 5 ​​are used to enclose the enclosing structure formed by the front baffle component 2, the base component 1, the first backrest component 41, and the second backrest component 42 from the side. In the passenger-carrying state, the side wings 5 ​​can protect the riding toddler from the side.

[0157] Furthermore, in the passenger-carrying mode, the folding locking member 33 and the slot 34 of this embodiment can cooperate with each other to limit the forward flipping of the second backrest member 42 through the limiting folding mechanism 3, so that the two-wheeled vehicle multi-functional child seat cannot be switched from the passenger-carrying mode to the cargo-carrying mode.

[0158] In this embodiment, the base component 1, the first backrest component 41, the side wing component 5, the second backrest component 42, the first folding component 31, the second backrest component 42, the second folding component 32, and the first backrest component 41 are all integrally formed from the same material. In this embodiment, the positioning protrusion 35 and the first folding component 31 are also integrally formed from the same material. In this embodiment, the positioning groove 36 is formed on the second folding component 32.

[0159] 12. Second embodiment of a multi-functional child seat for two-wheeled vehicles (Type II)

[0161] The base component 1 supports a child in passenger mode and forms a barrier around the bottom in cargo mode. The front barrier component 2 is hinged to the front end of the base component 1 via a pivot 21. In cargo mode, the front barrier component 2 blocks the front of the seat; in passenger mode, it can be flipped backward onto the base component. The pivot 21 limits the maximum angle at which the front barrier component 2 can be flipped forward.

[0162] The folding mechanism 3 includes a first folding member 31, a folding locking member 33, and a second folding member 32. The folding locking member 33 is hinged to the second folding member 32. The first folding member 31 has a slot 34 that can cooperate with the folding locking member 33 to unidirectionally limit the folding mechanism 3 in the cargo-carrying state, preventing the two-wheeled vehicle's multi-functional child seat from being converted to a passenger-carrying state. The second folding member 32 has a positioning protrusion 35, and the first folding member 31 has a positioning groove 36. The positioning protrusion 35 and the positioning groove 36 limit the maximum unfolding angle of the folding mechanism 3 in the passenger-carrying state.

[0163] The backrest 4 includes a first backrest component 41 and a second backrest component 42. The first backrest component 41 is fixed to the rear end of the base component 1. The second backrest component 42 is directly hinged to the first backrest component 41 via a folding mechanism 3. The maximum angle at which the second backrest component 42 and the first folding mechanism 31 rotate forward around the hinge point is limited by the front baffle component 2. When the second backrest component 42 rotates forward around the hinge point and is limited by the front baffle component 2, the front baffle component 2, the base component 1, the first backrest component 41, and the second backrest component 42 together form an enclosing structure. The side wings 5 ​​are fixed to the left and right sides of the second backrest component 42 and rotate together with the second backrest component 42. In the cargo-carrying state, the side wings 5 ​​are used to enclose the enclosing structure formed by the front baffle component 2, the base component 1, the first backrest component 41, and the second backrest component 42 from the side. In the passenger-carrying state, the side wings 5 ​​can protect the riding toddler from the side.

[0164] Furthermore, in the passenger-carrying mode, the folding locking member 33 and the slot 34 of this embodiment can cooperate with each other to limit the forward flipping of the second backrest member 42 through the limiting folding mechanism 3, so that the two-wheeled vehicle multi-functional child seat cannot be switched from the passenger-carrying mode to the cargo-carrying mode.

[0165] Furthermore, the two-wheeled multi-functional child seat of this embodiment also includes: a base side 14. The base side 14 is fixed to the base member 1 and is used together with the side wing member 5 to side-enclose the seat, thereby reducing the area of ​​the side wing member 5 and increasing the range of motion of the child's arms.

[0166] In this embodiment, the base component 1, the first backrest component 41, the side wing component 5, the second backrest component 42, the first folding component 31, the second backrest component 42, the second folding component 32, and the first backrest component 41 are all integrally formed from the same material. In this embodiment, the position protrusion 35 is fixed to the second folding component 32.

[0167] 13. Third embodiment of two types of multi-functional child seats for two-wheeled vehicles (Type II)

[0168] like Figure 29 and Figure 30 As shown, this embodiment provides a multi-functional child seat for a two-wheeled vehicle, including: a base component 1, a front panel component 2, a folding mechanism 3, a backrest 4, and side wings 5.

[0169] The base component 1 supports a child in passenger mode and forms a barrier around the bottom in cargo mode. The front barrier component 2 is hinged to the front end of the base component 1 via a pivot 21. In cargo mode, the front barrier component 2 blocks the front of the seat; in passenger mode, it can be flipped backward onto the base component. The pivot 21 limits the maximum angle at which the front barrier component 2 can be flipped forward.

[0170] The folding mechanism 3 includes a first folding member 31, a folding locking member 33, and a second folding member 32. The folding locking member 33 is slidably mounted on the second folding member 32, and its sliding direction is up and down when in passenger use. The first folding member 31 is provided with a slot 34, which can cooperate with the folding locking member 33 to unidirectionally limit the folding mechanism 3 when in cargo use, preventing the two-wheeled vehicle's multi-functional child seat from being converted to passenger use. The second folding member 32 is provided with a positioning protrusion 35, and the first folding member 31 is provided with a positioning groove 36. The positioning protrusion 35 and the positioning groove 36 limit the maximum unfolding angle of the folding mechanism 3 when in passenger use.

[0171] The backrest 4 includes a first backrest component 41 and a second backrest component 42. The first backrest component 41 is fixed to the rear end of the base component 1. The second backrest component 42 is directly hinged to the first backrest component 41 via a folding mechanism 3. The maximum angle at which the second backrest component 42 and the first folding mechanism 31 rotate forward around the hinge point is limited by the front baffle component 2. When the second backrest component 42 rotates forward around the hinge point and is limited by the front baffle component 2, the front baffle component 2, the base component 1, the first backrest component 41, and the second backrest component 42 together form an enclosing structure. The side wings 5 ​​are fixed to the left and right sides of the second backrest component 42 and rotate together with the second backrest component 42. In the cargo-carrying state, the side wings 5 ​​are used to enclose the enclosing structure formed by the front baffle component 2, the base component 1, the first backrest component 41, and the second backrest component 42 from the side. In the passenger-carrying state, the side wings 5 ​​can protect the riding toddler from the side.

[0172] Furthermore, in the passenger-carrying mode, the folding locking member 33 and the slot 34 of this embodiment can cooperate with each other to limit the forward flipping of the second backrest member 42 through the limiting folding mechanism 3, so that the two-wheeled vehicle multi-functional child seat cannot be switched from the passenger-carrying mode to the cargo-carrying mode.

[0173] Furthermore, the two-wheeled multi-functional child seat of this embodiment also includes: a lock body 91 and a lock plate 92. The lock body 91 is fixed to the second backrest 42 via the side wing 5, and the lock plate 92 is fixed to the lock body 91. Operating the lock body 91 causes the lock plate 92 to rotate, thereby limiting the folding locking member 33.

[0174] Furthermore, the two-wheeled vehicle multi-functional child seat of this embodiment also includes: a rear pull rod 37, which is indirectly connected to the folding locking member 33, so as to limit the folding locking member 33 from a distance; a front and rear connecting rod 38, which is a rigid member, used to connect the folding locking member 33 and the rear pull rod 37; and a rear longitudinal connecting member 39, which is fixed to the folding mechanism 3, and the rear pull rod slides 37 on the rear longitudinal connecting member 39.

[0175] The two-wheeled multi-functional child seat of this embodiment also includes: a base side 14. The base side 14 is fixed to the base member 1 and is used together with the side wing member 5 to surround the seat from the side, thereby reducing the area of ​​the side wing member 5 and increasing the range of motion of the child's arms. In this embodiment, the base member 1, the first backrest member 41, the first folding member 31, and the base side 14 are four parts integrally formed from the same material. In this embodiment, the side wing member 5, the second backrest member 42, the second folding member 32, and the rear longitudinal connecting member 39 are four parts integrally formed from the same material.

In this embodiment, the positioning protrusion 35 is fixed to the second folding member 32, and the positioning groove 36 is formed in the first folding member 31.

[0176] 14. Fourth embodiment of two types of multi-functional child seats for two-wheeled vehicles (Type II)

[0177] like Figure 31 and Figure 32 As shown, this embodiment provides a multi-functional child seat for a two-wheeled vehicle, including: a base component 1, a front panel component 2, a folding mechanism 3, a backrest 4, and side wings 5.

[0178] The base component 1 supports a child in passenger mode and forms a barrier around the bottom in cargo mode. The front barrier component 2 is hinged to the front end of the base component 1 via a pivot 21. In cargo mode, the front barrier component 2 blocks the front of the seat; in passenger mode, it can be flipped backward onto the base component. The pivot 21 limits the maximum angle at which the front barrier component 2 can be flipped forward.

[0179] The folding mechanism 3 includes a first folding member 31, a folding locking member 33, and a second folding member 32. The folding locking member 33 is a bolt and is detachably mounted on the second folding member 32. The first folding member 31 has a slot 34 that can cooperate with the folding locking member 33 to unidirectionally limit the folding mechanism 3 in the cargo-carrying state, preventing the two-wheeled vehicle's multi-functional child seat from being converted to a passenger-carrying state. The second folding member 32 has a positioning protrusion 35, and the first folding member 31 has a positioning groove 36. The positioning protrusion 35 and the positioning groove 36 limit the maximum unfolding angle of the folding mechanism 3 in the passenger-carrying state.

[0180] The backrest 4 includes a first backrest component 41 and a second backrest component 42. The first backrest component 41 is fixed to the rear end of the base component 1. The second backrest component 42 is directly hinged to the first backrest component 41 via a folding mechanism 3. The maximum angle at which the second backrest component 42 and the first folding mechanism 31 rotate forward around the hinge point is limited by the front baffle component 2. When the second backrest component 42 rotates forward around the hinge point and is limited by the front baffle component 2, the front baffle component 2, the base component 1, the first backrest component 41, and the second backrest component 42 together form an enclosing structure. The side wings 5 ​​are fixed to the left and right sides of the second backrest component 42 and rotate together with the second backrest component 42. In the cargo-carrying state, the side wings 5 ​​are used to enclose the enclosing structure formed by the front baffle component 2, the base component 1, the first backrest component 41, and the second backrest component 42 from the side. In the passenger-carrying state, the side wings 5 ​​can protect the riding toddler from the side.

[0181] This embodiment has two usage states, and the specific switching process is as follows: In the passenger-carrying usage state, rotate the folding locking member 33 to move it laterally and away from the slot 34, thereby releasing the restriction on the folding mechanism 3. Push the second backrest member 42 to flip forward until it is restricted by the front blocking member 2. Rotate the folding locking member 33 in the opposite direction to make it embed into the slot 34, thereby restricting the folding mechanism 3 and restricting the rearward flipping of the second backrest member 42. The specific structure after completing the state switch and entering the cargo-carrying usage state is as follows. Figure 32 As shown.

[0182] Furthermore, in the passenger-carrying mode, the folding locking member 33 and the slot 34 of this embodiment can cooperate with each other to limit the forward flipping of the second backrest member 42 through the limiting folding mechanism 3, so that the two-wheeled vehicle multi-functional child seat cannot be switched from the passenger-carrying mode to the cargo-carrying mode.

[0183] Furthermore, the two-wheeled multi-functional child seat of this embodiment also includes: a lock body 91 and a lock plate 92. The lock body 91 is fixed to the second backrest 42 via the side wing 5, and the lock plate 92 is fixed to the lock body 91. Operating the lock body 91 causes the lock plate 92 to rotate, thereby limiting the folding locking member 33.

[0184] Furthermore, the two-wheeled vehicle multi-functional child seat of this embodiment also includes: a rear pull rod 37, which is indirectly connected to the folding locking member 33, so as to limit the folding locking member 33 from a distance; a front and rear connecting rod 38, which is a rigid member, used to connect the folding locking member 33 and the rear pull rod 37; and a rear longitudinal connecting member 39, which is fixed to the second folding member 32, and the rear pull rod slides 37 on the rear longitudinal connecting member 39.

[0185] In this embodiment, the first folding member 31 is fixed to the first backrest member 41, and the second folding member 32 is indirectly connected to the second backrest member 42 via the side wing member 5. In this embodiment, there are two of each of the first and second folding members 31, and one of each of the rear pull rod 37 and the front-rear connecting rod 38. In this embodiment, one end of the front-rear connecting rod 38 is sleeved on the folding locking member 33, and the other end is fixed to the rear pull rod 37. The front-rear connecting rod 38 does not rotate with the folding locking member 33, but only moves laterally with it. The locking plate 92 indirectly limits the lateral movement of the folding locking member 33 by limiting the lateral movement of the rear pull rod 37.

[0186] This application provides a type of multi-functional child seat for two-wheeled vehicles with two usage modes, catering to both passenger and cargo needs when installed as a rear-mounted child seat. To achieve this, a folding mechanism 3 is an indispensable technical feature. The folding mechanism 3 has a limiting function, allowing the multi-functional child seat to remain in either passenger or cargo-carrying mode. Both independent claims in this application include the folding mechanism 3, thus satisfying the unity of invention requirement.
