Description

Technical Field

[0001] The present invention relates to a children's vehicle.

Background Art

[0002] Children's vehicles have become common products in the process of children's growth. Common children's vehicles include scooters, balance bikes, and so on. For example, when a child plays with a scooter, the child holds the steering component with both hands, steps on the bottom support frame with one foot, and slides by pedaling the ground with the other foot; for another example, when a child plays with a balance bike, the child holds the steering component with both hands, sits on the seat part of the balance bike, and then slides by pedaling the ground with both feet. However, the current existing balance bikes and scooters have relatively single functions. If a child wants to have both a scooter and a balance bike, two children's vehicles need to be purchased, which will inevitably increase the family living cost. Therefore, more and more users hope that a children's vehicle that can be used as both a scooter and a balance bike will appear.

[0003] Therefore, the present invention comes into being.

[0043] Embodiment 1:

[0044] As Figures 1 to 4 shown, a children's vehicle includes a support frame 1. One side of the support frame 1 is connected with a steering assembly 2 having a front wheel 21. The other side of the support frame 1 is connected with a bottom support frame 3 that can be stepped on by a child. The rear side of the bottom support frame 3 is connected with a rear wheel 4. The children's vehicle further includes a support rod 5 that can be both stored in the bottom support frame 3 and vertically connected relative to the bottom support frame 3. A storage space 31 for storing the support rod 5 is provided on the bottom support frame 3. The children's vehicle further includes a seat portion 6 that can be connected to the support rod 5 for a child to sit on and can be detached from the support rod 5 so that the support rod 5 can be stored. When the children's vehicle is in use, the user can vertically connect the support rod 5 to the bottom support frame 3 and install the seat portion 6 on the support rod 3. At this time, the child can sit on the seat portion 6, hold the steering assembly 2 with both hands, and slide by pedaling on the ground, using the children's vehicle as a balance bike to exercise balance. When the child wants to use the children's vehicle as a scooter, just detach the seat portion 6 from the support rod 5 and then store the support rod 5 in the storage space 31 on the bottom support frame 3. At this time, the child can hold the steering assembly 2 with both hands, step on one foot on the bottom support frame 3, and slide by pedaling on the other foot. Therefore, the children's vehicle of the present invention can be used as both a scooter and a balance bike, serving multiple purposes, reducing the cost of family life, bringing happiness to the growth of children, and being very simple and fast to operate during the switching process between the scooter and the balance bike.

[0045] As Figures 1 to 4 shown, the support rod 5 is rotatably connected to the bottom support frame 3 around a first axis A, and the storage space 31 is a strip-shaped groove provided on the bottom support frame 3 along the front-rear direction of the bottom support frame 3. When it is necessary to use the children's vehicle as a balance bike, just turn the support rod 5 out of the strip-shaped groove and vertically connect it to the bottom support frame 3, and then connect the seat portion 6. The operation is very convenient and fast.

[0046] As Figure 12 and Figure 15As shown, two opening slots 51 are provided at the lower end of the support rod 5. An operating block 72 is rotatably connected to the bottom support frame 3 through a connecting shaft 71. A locking shaft 73 is provided on the operating block 72, which can cooperate with the opening slot 51 to lock the relative position between the support rod 5 and the bottom support frame 3. A torsion spring 74 is provided on the connecting shaft 71, with one end abutted against the bottom support frame 3 and the other end abutted against the operating block 72. When the support rod 5 is stored in the storage space 31, the locking shaft 73 is inserted into one of the opening slots 51 to keep the support rod 5 in the stored state. When the support rod 5 is erected and vertically connected to the bottom support frame 3, the locking shaft 73 is inserted into the other opening slot 51 to keep the vertical state of the support rod 5. During operation, only by rotating the operating block 73 can unlocking and locking be performed, and the operation is very convenient and fast.

[0047] As Figures 1 to 4 shown, the steering assembly 2 includes a steering fork 22 that can rotate relative to the support frame 1. The front wheel 21 is connected to the steering fork 22. A steering rod 23 is connected to the steering fork 22. The upper end of the steering rod 23 is connected to a steering handle 24. A hanging position 25 for hanging the seat part 6 when the seat part 6 is separated from the support rod 5 is provided on the steering rod 23. When the children's vehicle is used as a scooter, the seat part 6 removed from the support rod 5 can be hung on the steering rod 23. When the children's vehicle is used as a balance bike, the seat part 6 can be removed from the steering rod 23. Such a structural design facilitates the storage of the seat part 6.

[0048] As Figures 1 to 4 shown, the hanging position 25 is a hook provided on the steering rod 23, and a hanging hole (not marked in the figure) that can cooperate with the hook is provided on the seat part 6.

[0049] As Figure 6 and Figure 12 shown, a footrest 26 is detachably connected to the front wheel 21. The seat part 6 includes an upper shell 61 and a lower shell 62 that can open and close relative to the upper shell 61. A storage space 63 for storing the footrest 26 is formed between the lower shell 62 and the upper shell 61. When the children's vehicle is in the balance bike state, the footrest 26 can also be installed on the front wheel 21 for the child to step on and ride. When the footrest 26 is not needed, the footrest 26 is placed in the storage space 63 on the seat part 6, which is very convenient for the use and storage of the footrest 26.

[0050] As Figure 2 and Figure 9As shown, the support frame 1 and the bottom support frame 3 are rotatably connected about the second axis B, and a locking member 8 is further provided between the support frame 1 and the bottom support frame 3 to lock their positions when they are relatively unfolded. Therefore, when it is necessary to carry or store the baby carriage, the baby carriage can be first adjusted to the balance bike state, and then the steering assembly 2 and the support frame 1 are rotated relative to the bottom support frame 3, so that the baby carriage can be folded to reduce the occupied space and facilitate carrying and storage.

[0051] As Figure 2 and Figure 10 shown, the locking member 8 includes a locking shaft 81 that can horizontally pass through the support frame 1 and the bottom support frame 3. The locking shaft 81 has a connecting end 81a and a locking end 82b. A U-shaped bar 82 that can span the support frame 1 is rotatably connected to the connecting end 81a. A locking ring 83 that can sleeve the locking end 81b to lock the support frame 1 and the bottom support frame 3 is provided on the U-shaped bar 82. When the baby carriage is in the unfolded state, the locking shaft 81 passes through the support frame 1 and the bottom support frame 3 at the same time, and the locking ring 83 of the U-shaped bar 82 is sleeved on the locking end 81b of the locking shaft 81, so as to prevent the locking shaft 81 from falling off. When the baby carriage needs to be folded, only the U-shaped bar 82 needs to be rotated to separate the locking ring 83 from the locking shaft 81. At this time, the locking shaft 81 can be pulled out, and the support frame 1 and the bottom support frame 3 can rotate relative to each other and fold.

[0052] As Figures 1 to 6 , and Figure 8 shown, a left bracket 91 and a right bracket 92 that can rotate relative to it are provided at the rear side of the bottom support frame 3. The rear wheel 4 includes a left rear wheel 41 that is rotatably connected to the left bracket 91 and can rotate from the outside of the left bracket 91 to the inside of the left bracket 91. The rear wheel 4 further includes a right rear wheel 42 that is rotatably connected to the right bracket 92 and can rotate from the outside of the right bracket 92 to the inside of the right bracket 92. Therefore, the opening degree between the left rear wheel 41 and the right rear wheel 42 can be adjusted by rotating the left bracket 91 and the right bracket 92, so that the baby carriage can be used as a tricycle, a scooter, a baby walker, and a balance bike, so that the baby carriage has a very many functions.

[0053] As Figure 8 , Figures 11 to 14As shown in the figure, the steering lever 23 includes an outer tube 231 fixedly connected to the steering fork 22 and an inner tube 232 that can move up and down within the outer tube 231. The upper end of the inner tube 232 is connected to a handlebar 24. A locking device is provided between the inner tube 232 and the outer tube 231 for locking their relative positions. The locking device includes a first locking assembly 11 provided between the upper sides of the inner tube 232 and the outer tube 231, and the locking device further includes a second locking assembly 12 and a third locking assembly 13 provided between the lower sides of the inner tube 232 and the outer tube 231. An operating assembly 10 is provided on the handlebar 24 and is connected to the third locking assembly 13 and can operate the third locking assembly 13 to unlock after the first locking assembly 11 and the second locking assembly 12 are unlocked. By using the first locking assembly 11, the second locking assembly 12, and the third locking assembly 13 to lock the inner tube 232 and the outer tube 231, the relative position between the inner tube 232 and the outer tube 231 can be locked. The user can adjust the height of the handlebar 24 by pulling and pushing the inner tube 232 to adapt to children of different heights. And by adopting three groups of locking structures, it is ensured that accidental unlocking will not occur, ensuring safety.

[0054] As Figures 11 to 14 shown, the first locking assembly 11 includes a first locking seat 111 connected to the outer tube 231. A locking piece 112 is provided in the first locking seat 111 and can move horizontally therein and pass through the wall of the outer tube 231. A plurality of first locking holes 113 that can be engaged with or disengaged from the locking piece 112 are provided on the inner tube 232. A toggle button 114 is connected to the first locking seat 111 and can rotate relative thereto and can push the locking piece 112 to move horizontally when rotating. A first return spring 115 that can push the locking piece 112 to move horizontally and reset is further provided in the first locking seat 111. At least two positioning grooves 116 are provided on the first locking seat 111. A positioning protrusion 117 that can be engaged with the positioning groove 116 for positioning after the toggle button 114 rotates relative to the first locking seat 111 is provided on the toggle button 114. When the first locking assembly 11 is in the locked state, the positioning protrusion 117 is engaged in one of the positioning grooves 116, the toggle button 114 keeps pressing the locking piece 112, and the locking piece 112 is inserted into the first locking hole 113. After rotating the toggle button 114 and making the positioning protrusion 117 engage in another positioning groove 116, the locking piece 112 moves horizontally under the action of the first return spring 115 and exits the first locking hole 113. At this time, the first locking assembly 11 is unlocked, and at this time, the second locking assembly 12 can be further operated.

[0055] As Figures 11 to 14As shown in the figure, the second locking assembly 12 includes a second locking seat 121 sleeved on the outer tube 231 and a fixed seat 122 arranged inside the inner tube 232. A locking post 123 is arranged inside the fixed seat 122 and can move horizontally therein and pass through the tube wall of the inner tube 232. A second locking hole 124 capable of engaging with or disengaging from the locking post 123 is arranged on the outer tube 231. A second return spring 125 capable of pushing the locking post 123 to move horizontally and reset is further arranged inside the inner tube 232. A button 126 is arranged on the second locking seat 121 and can slide relative to it after being pressed to push the locking post 123 out of the second locking hole 124. After the first locking assembly 11 is unlocked, when the button 126 is pressed, the button 126 pushes the locking post 123 out of the second locking hole 124. At this time, the second locking assembly 12 is unlocked. At this time, while keeping the button 126 pressed, the operating assembly 10 is operated to enable the operating assembly 10 to drive the third locking assembly 13 to unlock. Therefore, when operating, one hand needs to press the button 126 and the other hand needs to operate the operating assembly 10. Because there is a relatively long distance between the operating assembly 10 and the second locking assembly 12, it is ensured that only adults can operate, avoiding potential safety hazards caused by children's operation.

[0056] As Figures 11 to 14 shown, the third locking assembly 13 includes a locking block 131 that can move horizontally inside the inner tube 232 and pass through the tube wall of the inner tube 232. A plurality of third locking holes 132 capable of engaging with or disengaging from the locking block 131 are arranged on the outer tube 231. A sliding seat 133 connected to the operating assembly 10 and capable of sliding up and down inside the fixed seat 122 under the drive of the operating assembly 10 is arranged inside the inner tube 232. A transverse shaft 134 is arranged on the locking block 131. A driving inclined surface 135 capable of touching the transverse shaft 134 and pushing the locking block 131 to move horizontally is arranged on the sliding seat 133 when it slides longitudinally. A third return spring 136 capable of pushing the locking block 131 to move horizontally and reset is further arranged inside the fixed seat 122. When the button 126 is kept pressed and the operating assembly 10 is operated, the operating assembly 10 pushes the sliding seat 133 to slide downward. The driving inclined surface 135 on the sliding seat 133 pushes the transverse shaft 134, so that the locking block 131 exits from the third locking hole 132 on the outer tube 231. At this time, the steering handle 24 can be lifted upward to adjust the height. The operation is simple, and it is safe and reliable.

[0057] As Figures 11 to 14As shown, the operation component 10 includes a sliding button 101 provided on the handlebar 24 and capable of sliding downward relative to the handlebar 24 after being pressed. A push rod 102 is provided between the sliding button 101 and the sliding seat 133, which can push the sliding seat 133 to slide downward when the sliding button 101 slides downward. A fourth return spring 103 is also provided between the handlebar 24 and the sliding button 101 to push the sliding button 101 to reset upward. During operation, only need to press the sliding button 101, and the operation is very convenient and fast.
