Detailed Description
The technical solution of the present invention is further explained with reference to the drawings and the specific embodiments.
As shown in fig. 1 to 9, the child vehicle of the present invention includes an underframe 1, an upper surrounding frame 2 and a push rod 3, wherein the upper surrounding frame 2 is located above the underframe 1, and the push rod 3 is arranged on the underframe 1 and is used for pushing or pulling the child vehicle. The child's vehicle further comprises a front wheel assembly 4 disposed at the bottom front portion of the chassis 1 and a rear wheel assembly 5 disposed at the bottom rear portion of the chassis 1.
The buggy has an unfolded state and a folded state. When the stroller is in the unfolded state, the upper surrounding frame 2 is in the unfolded position, and is away from the bottom frame 1, and an accommodating space is formed between the bottom frame 1 and the upper surrounding frame 2, and the accommodating space is used for seating and lying for children or placing articles, as shown in fig. 1 to 3. When the stroller is in the folded position, the upper enclosure frame 2 is in the folded position, and it is brought close to the base frame 1, as shown in fig. 6 to 8. Preferably, the upper enclosure frame 2 is parallel to the base frame 1 in both the deployed and folded positions.
The child's vehicle also comprises a folding mechanism which is connected between the bottom frame 1 and the upper surrounding frame 2. The folding mechanism can be unfolded and folded, the upper surrounding frame 2 can be driven to be in the unfolded position through the unfolding action of the folding mechanism, and the upper surrounding frame 2 can be driven to be in the folded position through the folding action of the folding mechanism.
Specifically, the folding mechanism comprises a first connecting rod component and a second connecting rod component.
The first link assembly includes a first upper link 61 and a first lower link 62, an upper end of the first upper link 61 is rotatably connected to the upper surrounding frame 2 via a first shaft 71, a lower end of the first lower link 62 is rotatably connected to the base frame 1 via a second shaft 72, and a lower end of the first upper link 61 is rotatably connected to an upper end of the first lower link 62 via a third shaft 73.
The second connecting rod assembly comprises a second upper connecting rod 63 and a second lower connecting rod 64, the upper end part of the second upper connecting rod 63 is rotatably connected with the upper surrounding frame 2 through a fourth shaft 74, the lower end part of the second lower connecting rod 64 is rotatably connected with the underframe 1 through a fifth shaft 75, and the lower end part of the second upper connecting rod 63 is rotatably connected with the upper end part of the second lower connecting rod 64 through a sixth shaft 76.
The first shaft 71, the second shaft 72, the third shaft 73, the fourth shaft 74, the fifth shaft 75, and the sixth shaft 76 are arranged in parallel.
When the folding mechanism is in the unfolding state, the upper enclosure frame 2 is in the unfolding position, and the first upper connecting rod 61 is far away from the first lower connecting rod 62, so that a relatively large included angle is formed between the first upper connecting rod and the first lower connecting rod; the second upper link 63 is spaced from the second lower link 64 to form a relatively large angle therebetween. When the folding mechanism is in a folding state, the upper enclosure frame 2 is in a folding position, and the first upper connecting rod 61 is close to the first lower connecting rod 62, so that a relatively small included angle is formed between the two; the second upper link 63 is also adjacent to the second lower link 64, forming a relatively small angle therebetween.
Preferably, the first link assembly and the second link assembly are symmetrically disposed between the base frame 1 and the upper surrounding frame 2.
The first connecting rod component and the second connecting rod component are matched, so that when one of the first connecting rod component and the second connecting rod component is actuated, the other one of the first connecting rod component and the second connecting rod component can be driven to synchronously actuate, namely when the first upper connecting rod 61 and the first lower connecting rod 62 are relatively rotated to be close to each other, the second upper connecting rod 63 and the second lower connecting rod 64 are relatively rotated to be close to each other; when the first upper link 61 and the first lower link 62 rotate relatively and move away from each other, the second upper link 63 and the second lower link 64 rotate relatively and move away from each other synchronously, which enables the upper enclosure frame 2 to always keep parallel with the base frame 1 to perform up-and-down translational movement without twisting when being folded or unfolded.
In one embodiment, the first upper link 61 and the second upper link 63 are coupled to achieve synchronous motion of the first link assembly and the second link assembly.
Specifically, the first upper link 61 includes a first upper rod 611 and a first gear 612 fixedly disposed at an upper end of the first upper rod 611, the first gear 612 is rotatably connected to the upper enclosure frame 2 via a first shaft 71, and a lower end of the first upper rod 611 is rotatably connected to an upper end of the first lower link 62 via a third shaft 73. The second upper link 63 includes a second upper rod 631 and a second gear 632 fixedly disposed at an upper end of the second upper rod 631, the second gear 632 is rotatably connected to the upper peripheral frame 2 through the fourth shaft 74, a lower end of the second upper rod 631 is rotatably connected to an upper end of the second lower link 64 through the sixth shaft 76, and the first gear 612 is engaged with the second gear 632, as shown in fig. 3 and 4.
When the first upper link 61 rotates relative to the first lower link 62, the first gear 612 rotates relative to the upper enclosure frame 2, and the second gear 632 rotates relative to the upper enclosure frame 2 by the engagement of the first gear 612 and the second gear 632, so that the second upper link 63 and the second lower link 64 rotate relative to each other. Conversely, when the second upper link 63 rotates relative to the second lower link 64, the first upper link 61 can synchronously rotate relative to the first lower link 62 through the engagement of the first gear 612 and the second gear 632, so as to realize the synchronous action of the first link assembly and the second link assembly.
In yet another embodiment, the first and second lower links 62, 64 may be coupled to achieve simultaneous actuation of the first and second link assemblies.
Specifically, the first lower link 62 includes a first lower rod 621 and a third gear 622 fixedly disposed at a lower end of the first lower rod 621, the third gear 622 is rotatably connected to the chassis 1 via a second shaft 72, and an upper end of the first lower rod 621 is rotatably connected to a lower end of the first upper link 61 via a third shaft 73. The second lower link 64 includes a second lower rod 641 and a fourth gear 642 fixedly disposed at a lower end portion of the second lower rod 641, the fourth gear 642 is rotatably connected to the base frame 1 via the fifth shaft 75, an upper end portion of the second lower rod 641 is rotatably connected to a lower end portion of the second upper link 63 via the sixth shaft 76, and the third gear 622 is engaged with the fourth gear 642, as shown in fig. 3 and 5.
When the first upper link 61 and the first lower link 62 rotate relatively, the third gear 622 rotates relative to the chassis 1, and the fourth gear 642 also rotates relative to the chassis 1 by meshing the third gear 622 with the fourth gear 642, so that the second upper link 63 and the second lower link 64 rotate relatively. Conversely, when the second upper link 63 and the second lower link 64 rotate relatively, the first upper link 61 can rotate relatively to the first lower link 62 synchronously by the meshing of the third gear 622 and the fourth gear 642, so as to realize the synchronous action of the first link assembly and the second link assembly.
Of course, the above two embodiments may be adopted simultaneously, that is, the upper ends of the first upper link 61 and the second upper link 63 are engaged with the second gear 632 through the first gear 612, and the lower ends of the first lower link 62 and the second lower link 64 are engaged with the fourth gear 642 through the third gear 622. In this way, while the synchronous action of the first link assembly and the second link assembly is achieved to keep the upper enclosure frame 2 in translational movement upward or downward at all times, the structure of the locking mechanism of the child car for locking the upper enclosure frame 2 in the unfolded position is made simple, and only the positions of two members connected to each other among the upper enclosure frame 2, the first upper link 61, the first lower link 62, the chassis 1, the second lower link 64, and the second upper link 63 need to be locked.
The child stroller further comprises a first limiting structure, when the upper enclosure frame 2 is unfolded from the folding position, the action of the folding mechanism can be limited through the first limiting structure, so that the upper enclosure frame 2 is located at the unfolding position.
Specifically, as shown in fig. 3 to 5, the first limiting structure includes a first limiting portion 11 disposed on the bottom frame 1 and a second limiting portion 21 disposed on the upper enclosure frame 2, the first limiting portion 11 is disposed on two sides of the bottom frame 1, and the second limiting portion 21 is disposed on two sides of the upper enclosure frame 2. When the upper enclosure frame 2 is in the unfolded position, the first lower link 62 and the second lower link 64 are respectively abutted against and matched with the first limiting portion 11 at the corresponding position, and the first upper link 61 and the second upper link 63 are respectively abutted against and matched with the second limiting portion 21 at the corresponding position.
The child's bike further comprises a second limiting structure, when the upper enclosure frame 2 is folded from the unfolding position, the action of the folding mechanism can be limited through the second limiting structure, and therefore the upper enclosure frame 2 is located at the folding position.
Specifically, as shown in fig. 8 and 9, the second limiting structure includes a third limiting portion 12 disposed on the bottom frame 1 and a fourth limiting portion 22 disposed on the upper enclosure frame 2, the third limiting portion 12 is disposed on two sides of the bottom frame 1, and the fourth limiting portion 22 is disposed on two sides of the upper enclosure frame 2. When the upper frame 2 is in the folded position, the first lower connecting rod 62 and the second lower connecting rod 64 are respectively abutted against and matched with the third limiting portion 12 at the corresponding position, and the first upper connecting rod 61 and the second upper connecting rod 63 are respectively abutted against and matched with the fourth limiting portion 22 at the corresponding position.
In this embodiment, the folding mechanism is respectively disposed between the front end portion of the bottom frame 1 and the front end portion of the upper surrounding frame 2, and between the rear end portion of the bottom frame 1 and the rear end portion of the upper surrounding frame 2.
When the upper enclosure frame 2 is converted from the unfolded position to the folded position, after the locking mechanism is unlocked, the upper enclosure frame 2 is pressed downwards, the first upper link 61 and the first lower link 62 are relatively rotated and drawn together through the engagement of the first gear 612 and the second gear 632 and the engagement of the third gear 622 and the fourth gear 642, the second upper link 63 and the second lower link 64 are also relatively rotated and drawn together in synchronization, so that the upper enclosure frame 2 is horizontally moved downwards in a state of being parallel to the chassis 1 and drawn together with the chassis 1 until the first lower link 62 and the second lower link 64 are respectively abutted against the third limiting portion 12 at the corresponding position on the chassis 1 and are engaged, the first upper link 61 and the second upper link 63 are respectively abutted against the fourth limiting portion 22 at the corresponding position on the upper enclosure frame 2 and are engaged, the first upper link 61 and the first lower link 62 cannot be relatively rotated continuously in the current direction, the second upper link 63 and the second lower link 64 cannot be relatively rotated continuously in the current direction, and the upper enclosure frame 2, i.e. the folded position is shown in fig. 6-8.
When the upper frame 2 is in the folded position, the push rod 3 is close to the bottom frame 1, and the child car is in the folded state.
When the stroller is unfolded from the folded state, the push rod 3 is reversely moved to the unfolded position, and then the upper surrounding frame 2 is lifted upwards, the first upper link 61 and the first lower link 62 are relatively rotated and separated by the engagement of the first gear 612 and the second gear 632, and the third gear 622 and the fourth gear 642, and the second upper link 63 and the second lower link 64 are also relatively rotated and separated in synchronization, so that the upper surrounding frame 2 is kept parallel to the chassis 1 and is moved in an upward translational manner and separated from the chassis 1, until the first lower link 62 and the second lower link 64 are respectively abutted against and engaged with the first limiting portion 11 at the corresponding position on the chassis 1, the first upper link 61 and the second upper link 63 are respectively abutted against and engaged with the second limiting portion 21 at the corresponding position on the upper surrounding frame 2, the first upper link 61 and the first lower link 62 cannot be relatively rotated in the current direction, the second upper link 63 and the second lower link 64 cannot be relatively rotated in the current direction, and the upper surrounding frame 2 is located at the unfolded position, as shown in fig. 1 to 3.
