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] The carrying capacity of an electric bicycle is very limited. After installing a rear safety seat, a trunk cannot be installed, a safety helmet loses a safe storage space, and the willingness to use a high-quality safety helmet is limited. The willingness to use a front basket is not high, on the one hand, the front basket affects the steering feeling after carrying, and on the other hand, the front basket is not very aesthetic, and after installing a rear carrying rack, the bicycle also faces the problem of no place to store the helmet. SUMMARY
[0003] In order to solve the problem that it is difficult to install a rear child seat for carrying people and a rear trunk for carrying things on a two-wheeled vehicle such as a bicycle or an electric bicycle, the present application provides a multifunctional child seat for a two-wheeled vehicle. By folding part of the structure of the multifunctional child seat for a two-wheeled vehicle to form an enclosed space, and then locking, the multifunctional child seat for a two-wheeled vehicle has a carrying function, achieving the effect of one thing serving two purposes.
[0004] According to one aspect of the present application, a multifunctional child seat for a two-wheeled vehicle (first type) is provided, comprising: a base piece, a front barrier piece, a folding mechanism, a backrest, and a side wing piece.
[0005] The base piece is used to support a young child in a carrying state, and is used to form a barrier at the bottom in a carrying state.
[0006] The front barrier piece is fixed to the front end of the base piece or detachably connected to the front end of the base piece. The front barrier piece is used to enclose the front of the seat in a carrying state, and in a carrying state, the front barrier piece can also serve as a handrail for the young child to hold.
[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 changed 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 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 first type) cannot be changed 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 is 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 is a rigid piece used to connect the folding locking piece and the rear pull rod.
[0016] A rear longitudinal connecting piece is 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, a two-wheeled multifunctional child seat (second type) is provided, which includes 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 fixed to the front end of the base or detachably connected to the front end of the base. The front wall is used to enclose the front of the seat in the object-carrying state, and the front wall can also be used as a handrail for the child to hold in the human-carrying state.
[0020] The folding mechanism comprises 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 object-carrying state, so that the multifunctional child seat of the two-wheeled vehicle cannot be converted to the human-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 human-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 using gravity or friction. When the folding locking piece is hinged to the second folding piece, the self-locking of the folding mechanism can be realized by designing the center of gravity of the folding locking piece. The folding locking piece with threads can be detachably connected to the second folding mechanism, and the self-locking of the folding mechanism can also be realized. The elastic element is not a necessary component of the folding mechanism.
[0021] The backrest comprises a first backrest piece and a second backrest piece. The first backrest piece is fixed to the rear end of the base, and the second backrest piece is hinged to the first backrest piece directly or indirectly through the folding mechanism. The maximum angle of the second backrest piece forwardly turning around the hinge point is limited by the front wall. When the second backrest piece forwardly turns around the hinge point and is 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 wing piece is fixed to the left and right sides of the second backrest piece and turns with the second backrest piece. In the object-carrying state, the side wing piece is used to enclose the closed structure formed by the front wall, the base, the first backrest piece and the second backrest piece from the side, and the degree of enclosure can be partial or complete. In the human-carrying state, the side wing pieces fixed to the left and right sides of the second backrest piece can protect the child from the side.
[0023] Further, in order to solve the problem that the second backrest part is not limited in the forward direction in the manned state, which is not conducive to the installation and use of the safety belt, the above technical solution is improved: the folding locking part cooperates with the clamping groove to one-way limit the folding mechanism in the manned state, thereby limiting the forward direction of the second backrest part, so that the multifunctional child seat (first type) cannot be changed from the manned state to the cargo carrying state. The backrest part limited in the forward direction in the manned state is convenient for fixing the safety belt.
[0024] Further, in order to improve the comfort of the child and facilitate the child's arm movement, the above technical solution is improved: the introduction of the base side edge reduces the area of the side wing part and increases the movement range of the child's arm. The base side edge is directly or indirectly fixed to the base part and is used to block the seat from the side together with the side wing part. The base side edge can be directly fixed to the base part, indirectly connected to the base part through the first backrest part, or connected to both the base part and the first backrest part. After introducing the base side edge, the side wing part can subtract the corresponding area of the base side edge to improve the movement range of the child's arm. The base side edge can be connected to both the first backrest part and the base part to improve the structural strength of the seat.
[0025] Optionally, on the one hand, in the cargo carrying state, how to prevent theft needs to be considered, and on the other hand, in the manned state, the folding mechanism of the folding locking part needs to be considered. To this end, a lock body and a lock piece are introduced to limit the displacement of the folding locking part, which can serve as a security device to solve the problem of theft 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 part or directly or indirectly fixed to the second backrest part, and the lock piece is connected to the lock body to limit the folding locking part. The lock body can be indirectly fixed to the second backrest part through the side wing part, indirectly fixed to the first backrest part through the base side edge, or indirectly fixed to the first backrest part or the second backrest part through other mechanisms. For example, the lock body is indirectly fixed to the second folding part through a connecting piece, and is indirectly fixed to the second backrest part through the second folding part.
[0026] Further, the lock piece directly limits the folding locking part, which limits the fixing point of the lock body. In order to provide a wider fixing point for the lock body, the above technical solution is improved by introducing:
[0027] The rear pull rod is indirectly connected with the folding locking part, which is convenient for limiting the folding locking part from a distance;
[0028] The front and rear connecting rods are rigid parts used to connect the folding locking part and the rear pull rod;
[0029] The rear longitudinal connecting part is fixed to the folding mechanism, and the rear pull rod is slidably arranged in the rear longitudinal connecting part. Attached Figure Description

[0063] For the convenience of description, the following "front", "rear", "left", and "right" are determined according to the first perspective when a child is seated, and are independent of the left and right directions of the drawings themselves. For the sake of brevity, the two-wheeled vehicle multifunctional child seat provided in the following embodiments can be referred to simply as "seat".
[0064] 1. A first embodiment of a two-wheeled vehicle multifunctional child seat (first type)
[0065] As shown in Figure 1 and Figure 2 , the present embodiment provides a two-wheeled vehicle multifunctional child seat, which comprises a base member 1, a front wall member 2, a folding mechanism 3, a backrest 4, and a side wing member 5.
[0066] The base member 1 is used to support a young child when in a human-carrying use state, and is used to form a bottom wall when in a cargo-carrying use state.
[0067] The front wall 2 is fixed to the front end of the base 1. In the object-carrying state, the front wall 2 is used to enclose the front of the seat. In the child-carrying state, the front wall 2 can also be used as a handrail for the child to hold.
[0068] The folding mechanism 3 comprises a first folding part 31, a folding lock 33 and a second folding part 32. The folding lock 33 is slidably arranged on the second folding part 32, and the sliding direction is left-right transverse sliding. The first folding part 31 is provided with a clamping groove 34. On the one hand, the clamping groove 34 can cooperate with the folding lock 33 to unidirectionally limit the folding mechanism 3 in the object-carrying state, so that the multifunctional child seat cannot be converted to the child-carrying state. On the other hand, the clamping groove 34 can also cooperate with the folding lock 33 to unidirectionally limit the folding mechanism 3 in the child-carrying state, so as to limit the maximum unfolding angle of the folding mechanism 3.
[0069] The backrest 4 comprises a first backrest part 41 and a second backrest part 42. The first backrest part 41 is fixed to the rear end of the base 1, and the second backrest part 42 is directly hinged to the first backrest part 41 through the folding mechanism 3. The maximum angle of the second backrest part 42 and the first folding part 31 forwardly turning around the hinge point is limited by the front wall 2. When the second backrest part 42 forwardly turns around the hinge point and is limited by the front wall 2, the front wall 2, the base 1, the first backrest part 41 and the second backrest part 42 together form an enclosed structure.
[0070] The side wing 5 is fixed to the left and right sides of the second backrest part 42 and turns with the second backrest part 42. In the object-carrying state, the side wing 5 is used to enclose the structure formed by the front wall 2, the base 1, the first backrest part 41 and the second backrest part 42 from the side. In the child-carrying state, the side wing 5 can protect the child from the side.
[0071] The base 1 and the first backrest part 41 of the embodiment are two parts integrally formed of the same material. The side wing 5 and the second backrest part 42 of the embodiment are two parts integrally formed of the same material. The first folding part 31 and the second backrest part 42 of the embodiment are two parts integrally formed of the same material.
[0072] The embodiment has two states, and the specific switching process is as follows: in the child-carrying state, the folding lock 33 is pulled transversely to release the limitation of the folding mechanism 3, and the second backrest part 42 is pushed to forwardly turn until it is limited by the front wall 2. The folding lock 33 is embedded into the clamping groove 34, thereby limiting the folding mechanism 3 and limiting the backward turning of the second backrest part 42. After the state switching is completed, the specific structure in the object-carrying state is shown in Figure 2
[0073] Further, in the state of carrying a person, the folding locking member 33 and the clamping groove 3 can limit the folding mechanism 3, limit the forward turning of the second backrest member 42, and make the multifunctional child seat of the two-wheeled vehicle unable to change from the state of carrying a person to the state of carrying an object.
[0074] 2. A second embodiment of the multifunctional child seat of the two-wheeled vehicle (the first type).
[0075] As shown in Figure 3 and Figure 4 , the embodiment provides a multifunctional child seat of the two-wheeled vehicle, which comprises a base member 1, a front barrier member 2, a folding mechanism 3, a backrest 4, and a side wing member 5.
[0076] The base member 1 is used to support a child in the state of carrying a person and is used to form a barrier at the bottom in the state of carrying an object.
[0077] The front barrier member 2 is detachably connected to the front end of the base member 1. The front barrier member 2 is used to enclose the front part of the seat in the state of carrying an object, and in the state of carrying a person, the front barrier member 2 can be used as a handrail for the child to hold or can be detached to eliminate the hindrance to the placement of the child's legs and provide more space for the child to sit.
[0078] The folding mechanism 3 comprises a first folding member 31, a folding locking member 33, and a second folding member 32. The folding locking member 33 is slidably arranged on the second folding member 32, and in the state of carrying a person, the sliding direction is vertical. The first folding member 31 is provided with a clamping groove 34, which can cooperate with the folding locking member 33 to limit the folding mechanism 3 in one direction in the state of carrying an object, so that the multifunctional child seat of the two-wheeled vehicle cannot change to the state of carrying a person, and the clamping groove 34 can also cooperate with the folding locking member 33 to limit the folding mechanism 3 in one direction in the state of carrying a person, so as to limit the maximum unfolding angle of the folding mechanism 3.
[0079] The backrest 4 comprises a first backrest member 41 and a second backrest member 42. The first backrest member 41 is fixed to the rear end of the base member 1, and the second backrest member 42 is directly hinged to the first backrest member 41 through the folding mechanism 3. The maximum angle of forward turning of the second backrest member 42 and the first folding member 31 around the hinge point is limited by the front barrier member 2. When the second backrest member 42 is turned forward around the hinge point and is limited by the front barrier member 2, the front barrier member 2, the base member 1, the first backrest member 41, and the second backrest member 42 form a closed structure.
[0080] Side wing 5, fixed on the left and right sides of the second backrest 42, and turns over with the second backrest 42. In the carrying state, the side wing 5 is used to block the front wall 2, the base 1, the first backrest 41, and the second backrest 42 from the side, forming a closed structure. In the riding state, the side wing 5 can protect the child from the side.
[0081] The base 1 and the first backrest 41, the side wing 5 and the second backrest 42, the first folding part 31 and the second backrest 42, and the second folding part 32 and the first backrest 41 of the present embodiment are all integrally formed with the same material. The front wall 2 of the present embodiment partially blocks the front of the seat, and a hole is provided on it for the child to hold.
[0082] The present embodiment has two states, and the specific switching process is as follows: in the riding state, push the folding lock 33 away from the slot 34 to release the limit of the folding mechanism 3, and push the second backrest 42 forward until it is limited by the front wall 2. Push the folding lock 33 into the slot 34 to limit the folding mechanism 3 and the backward rotation of the second backrest 42. After the state switching is completed, the specific structure in the carrying state is shown in Figure 4 .
[0083] Further, in the riding state, the folding lock 33 and the slot 3 of the present embodiment can limit the folding mechanism 3 and the forward rotation of the second backrest 42, so that the multifunctional child seat cannot be switched from the riding state to the carrying state.
[0084] Further, the present embodiment also includes a base side 14 fixed to the base 1, which is used with the side wing 5 to block the seat from the side, thereby reducing the area of the side wing 5 and increasing the range of motion of the child's arms.
[0085] 3. A multifunctional child seat for a two-wheeled vehicle (first type) third embodiment
[0086] As shown in Figure 5 and Figure 6 , the present embodiment provides a multifunctional child seat for a two-wheeled vehicle, which includes a base 1, a front wall 2, a folding mechanism 3, a backrest 4, and a side wing 5.
[0087] The base 1 is used to support a child in a passenger mode and to form a surrounding structure in a cargo mode. The front surrounding part 2 is fixed to the front end of the base 1 and is used to surround the front of the seat in the cargo mode. The folding mechanism 3 comprises a first folding part 31, a folding locking part 33 and a second folding part 32. The folding locking part 33 is hinged to the second folding part 32. The first folding part 31 is provided with a clamping groove 34 which can cooperate with the folding locking part 33 to limit the folding mechanism 3 in one direction in the cargo mode, so that the multifunctional child seat cannot be converted from the passenger mode to the cargo mode. The clamping groove 34 can also cooperate with the folding locking part 33 to limit the folding mechanism 3 in one direction in the passenger mode, so as to limit the maximum unfolding angle of the folding mechanism 3.
[0088] The backrest 4 comprises a first backrest part 41 fixed to the rear end of the base 1 and a second backrest part 42 hinged to the first backrest part 41 through the folding mechanism 3. The maximum forward turning angle of the second backrest part 42 and the first folding part 31 around the hinge point is limited by the front surrounding part 2. When the second backrest part 42 is turned forward around the hinge point and is limited by the front surrounding part 2, the front surrounding part 2, the base 1, the first backrest part 41 and the second backrest part 42 form a surrounding structure. The side wing part 5 is fixed to the left and right sides of the second backrest part 42 and is turned together with the second backrest part 42. In the cargo mode, the side wing part 5 is used to surround the surrounding structure formed by the front surrounding part 2, the base 1, the first backrest part 41 and the second backrest part 42 from the side. In the passenger mode, the side wing part 5 can protect the child from the side.
[0089] The embodiment has two modes of use, and the specific switching process is as follows: in the passenger mode, the folding locking part 33 is pushed from the rear of the first backrest part 41 to move away from the clamping groove 34, so as to release the limitation of the folding mechanism 3. The second backrest part 42 is pushed to turn forward until it is limited by the front surrounding part 2.
