Description

Technical Field

[0001] This utility model relates to a children's tricycle. Background Technology

[0002] Children's tricycles are a common product during a child's growth. Traditional children's tricycles generally include a main frame, steering assembly, rear support assembly, seat, backrest, and a T-shaped push bar for adults to push. The push bar is located at the rear of the backrest. Therefore, current children's tricycles have the following shortcomings: 1. The push bar's location at the rear of the backrest prevents the backrest from being adjusted backward, preventing children from sitting in a semi-reclined or fully reclined position; 2. The T-shaped push bar provides poor stability when pushing the tricycle, especially on uneven surfaces, making it prone to tilting to the side.

[0003] Therefore, this utility model was created based on the above-mentioned shortcomings. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a children's tricycle with a simple structure, good stability, and the ability for children to sit in a semi-reclining or flat position.

The push rod assembly 5 is rotatably connected to the main frame 1 or the seat 4 about a third axis C.

[0010] A first transmission mechanism 7 is provided between the lower end of the push rod assembly 5 and the connecting seat 21, which can push the steering assembly 2 to rotate and fold relative to the main frame 1 when the push rod assembly 5 rotates and folds relative to the main frame 1. A second transmission mechanism 8 is provided between the connecting seat 21 and the rear support assembly 3, which can push the left rear leg 31 and the right rear leg 32 to rotate and fold relative to the main frame 1 when the steering assembly 2 rotates and folds relative to the main frame 1.

[0011] The first transmission mechanism 7 includes a rotating part 71 located at the lower end of the push rod assembly 5 and capable of rotating around the third axis C.

The lower left push rod 511 and the lower right push rod 521 are provided with T-shaped insertion seats 57 that can be inserted and matched with the insertion interfaces.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. The push rod assembly connected to the main frame or seat of this utility model includes a left push rod and a right push rod located on the left and right sides of the seat. A clearance space is formed between the left push rod and the right push rod, and there is no longer an obstruction in the space directly behind the seat. Therefore, after connecting a backrest that can rotate backward to the seat or connecting a flexible backrest pocket to the left and right push rods, the backrest or backrest pocket can be adjusted backward, allowing the child to recline or lie flat, so that the child can choose a riding posture according to actual needs for a more comfortable ride. In addition, a push handle is connected to the upper end of the left and right push rods. When an adult pushes the children's tricycle through the push handle, the force is transmitted through the left and right push rods on both sides of the main frame, which makes the children's tricycle move more smoothly and will not easily tilt, making it more convenient for adults to push.

[0018] 2. When the push rod assembly of this utility model rotates and folds relative to the main frame, it drives the steering assembly to rotate and fold towards the main frame through the first transmission mechanism. During the rotation and folding process of the steering assembly relative to the main frame, it drives the rear support assembly to rotate and fold relative to the main frame through the second transmission mechanism. This allows the children's tricycle to be folded and stored when not in use. Moreover, the steering assembly and the rear support assembly can be folded together by simply rotating the push rod assembly, making the folding operation convenient and quick.

[0019] 3. The canopy support of this utility model can move up and down with the upper left and upper right push rods. When an adult pushes the children's tricycle, the upper left and upper right push rods move upward and are in the unfolded state. At this time, the canopy support is in a high position, which can support the canopy cloth to provide shade or wind protection for the child inside the tricycle. When the child wants to ride the tricycle by himself, the canopy support and the upper left and upper right push rods can be moved downward and folded. The canopy support is in a low position, which is convenient for the child to ride. Moreover, when the canopy support is in a low position, it is also convenient for the children's tricycle to fold. Therefore, the canopy support moves up and down together with the upper left and upper right push rods, which is convenient for switching between adult pushing and child riding, and also facilitates the folding of the children's tricycle. The design is ingenious. Attached Figure Description

[0033] The present invention will be further described below with reference to the accompanying drawings:

[0034] like Figure 1 , Figure 2 , Figure 13 As shown, a children's tricycle includes a main frame 1. A steering assembly 2 with a front wheel 2a is connected to the front side of the main frame 1. A rear support assembly 3 is connected to the rear side of the main frame 1. The rear support assembly 3 includes a left rear leg 31 and a right rear leg 32 connected to the left and right sides of the main frame 1. The lower ends of the left rear leg 31 and the right rear leg 32 are connected to the rear wheel 3a. A seat 4 is provided on the main frame 1. A push rod assembly 5 extending upward is also provided on the main frame 1 or the seat 4. The push rod assembly 5 includes a left push rod 51 and a right push rod 52 spaced apart on the left and right sides of the seat 4. A clearance space 50 is formed between the left push rod 51 and the right push rod 52. A push handle 53 is connected to the upper end of the left push rod 51 and the right push rod 52. The push rod assembly 5 connected to the main frame 1 or seat 4 includes a left push rod 51 and a right push rod 52 located on the left and right sides of the seat 4. The space directly behind the seat 4 is no longer obstructed. Therefore, after the flexible backrest pocket 61 is connected to the left push rod 51 and the right push rod 52, the backrest pocket 61 can be adjusted backward, and the child can lie half-reclined or flat in the backrest pocket 61, so that the child can choose the riding posture according to actual needs, so as to ride more comfortably. In addition, a push handle 53 is connected to the upper end of the left push rod 51 and the right push rod 52. When an adult pushes the children's tricycle through the push handle 53, the force is transmitted through the left push rod 51 and the right push rod 52 on both sides of the main frame 1, which can make the children's tricycle move more smoothly and will not easily tilt, making it easier for adults to push.

[0035] like Figure 1 , Figure 4 and Figure 9 As shown, the left push rod 51 includes a lower left push rod 511 connected to the main frame 1 or the seat 4, and the right push rod 52 includes a lower right push rod 521 connected to the main frame 1 or the seat 4. The lower left push rod 511 is connected to an upper left push rod 512 that can slide and extend relative to it, and the lower right push rod 521 is connected to an upper right push rod 522 that can slide and extend relative to it. The push handle 53 is disposed at the upper end of the upper left push rod 512 and the upper right push rod 522 and connects the two. Of course, the upper left push rod 512 and the upper right push rod 522 can also be rotatably connected to the lower left push rod 511 and the lower right push rod 521, respectively. When an adult pushes the children's tricycle, the upper left push rod 512 and the upper right push rod 522 rotate relative to the lower left push rod 511 and the lower right push rod 521 and unfold. When an adult does not need to push the children's tricycle, the upper left push rod 512 and the upper right push rod 522 rotate relative to the lower left push rod 511 and the lower right push rod 521 and fold.

[0036] like Figure 2 and Figure 3 As shown, the steering assembly 2 includes a connecting seat 21 rotatably connected to the main frame 1 about a first axis A. A steering fork 22, rotatable relative to the connecting seat 21, is provided within the connecting seat 21. The front wheel 2a is mounted on the steering fork 22. A steering handle 23 is connected to the upper end of the steering fork 22. The left rear leg 31 and right rear leg 32 are rotatably connected to the main frame 1 about a second axis B. The push rod assembly 5 is rotatably connected to the main frame 1 or the seat 4 about a third axis C. Therefore, when the tricycle needs to be folded, the upper left push rod 512 and upper right push rod 522 are first slid downwards and retracted into the lower left push rod 511 and lower right push rod 521. Then, the push rod assembly 5 is rotated forward, causing it to rotate towards the main frame 1 about the third axis C. The steering assembly 2 rotates towards the main frame 1 about the first axis A, and the left rear leg 31 and right rear leg 32 rotate towards the main frame 1 about the second axis B.

[0037] like Figure 2 , Figure 3 , Figures 5 to 8 As shown, a first transmission mechanism 7 is provided between the lower end of the push rod assembly 5 and the connecting seat 21, which can drive the steering assembly 2 to rotate and fold relative to the main frame 1 when the push rod assembly 5 rotates and folds relative to the main frame 1. A second transmission mechanism 8 is provided between the connecting seat 21 and the rear support assembly 3, which can drive the left rear leg 31 and the right rear leg 32 to rotate and fold relative to the main frame 1 when the steering assembly 2 rotates and folds relative to the main frame 1. When the push rod assembly 5 rotates and folds relative to the main frame 1, it drives the steering assembly 2 to rotate and fold relative to the main frame 1 through the first transmission mechanism 7. During the rotation and folding process of the steering assembly 2 relative to the main frame 1, it drives the rear support assembly 3 to rotate and fold relative to the main frame 1 through the second transmission mechanism 8. This allows the children's tricycle to be folded and stored when not in use. Moreover, the coordinated folding of the steering assembly 2 and the rear support assembly 3 can be achieved simply by rotating the push rod assembly 5, making the folding operation convenient and quick.

[0038] like Figures 5 to 8 As shown, the first transmission mechanism 7 includes a rotating part 71 located at the lower end of the push rod assembly 5 and rotatable about a third axis C. A first transmission rod 72 is hinged to the rotating part 71 about a fourth axis D, offset from the third axis C. The other end of the first transmission rod 72 is hinged to the connecting seat 21 about a fifth axis E, offset from the first axis A. When the push rod assembly 5 rotates about the third axis C, the push rod assembly 5 pushes the second transmission rod 72, which in turn pushes the connecting seat 21 to rotate about the first axis A relative to the main frame 1, thereby realizing the linkage drive of the push rod assembly 5 to the steering assembly 2.

[0039] like Figures 5 to 8As shown, the rear support assembly 3 also includes a rotating seat 33 located on the upper ends of the left rear leg 31 and the right rear leg 32. The second transmission mechanism 8 includes multiple teeth 81 arranged circumferentially on the rotating seat 33. A transmission gear 82 rotatably connects to the main frame 1, meshing with the teeth 81. A second transmission rod 83 is hinged to the eccentric position of the transmission gear 82 around the sixth axis F. The other end of the second transmission rod 83 is hinged to the connecting seat 21 around the seventh axis G, offset from the first axis A. When the connecting seat 21 is pushed by the first transmission rod 72 and rotates around the first axis A, the connecting seat 21 pulls the second transmission rod 83, which in turn pulls the transmission gear 82 to rotate. The transmission gear 82, through its engagement with the teeth 81, causes the rotating seat 33 to rotate, thereby causing the left rear leg 31 and the right rear leg 32 to rotate and fold relative to the main frame 1. The entire transmission structure is simple and compact, making the children's tricycle flexible in folding and unfolding.

[0040] like Figure 7 and Figure 8 As shown, the first transmission rod 72 and the second transmission rod 83 are hinged to the same position on the connecting seat 21.

[0041] like Figure 1 , Figures 9 to 13As shown, the push rod assembly 5 also includes a canopy bracket 54 for supporting the canopy. The upper left push rod 512 and the upper right push rod 522 are provided with downwardly extending connecting rods 55. The canopy bracket 54 includes a collar 541 located at the lower end of the connecting rod 55 and sleeved on the lower left push rod 511 and the lower right push rod 521, which can slide with the upper left push rod 512 and the upper right push rod 522 when they slide relative to the lower left push rod 511 and the lower right push rod 521. The collar 541 is provided with a mounting seat 542, and a U-shaped support rod 543 that can support the canopy tarpaulin 59 is connected to the mounting seat 542. When an adult pushes the children's tricycle, the upper left push rod 512 and the upper right push rod 522 move upwards and are in the unfolded state. At this time, the canopy support 54 is in a high position, which can support the canopy tarpaulin 59 to provide shade or wind protection for the child inside the tricycle. When the child wants to ride the tricycle by himself, the canopy support 54, the upper left push rod 512 and the upper right push rod 522 can be moved downwards and folded. The canopy support 54 is in a low position, which is convenient for the child to ride. Moreover, when the canopy support 54 is in a low position, it is also convenient for the tricycle to fold. Therefore, the canopy support 54, the upper left push rod 512 and the upper right push rod 522 move up and down together, which is convenient for switching between adult pushing and child riding, and also makes it convenient for the tricycle to fold. Furthermore, the U-shaped support rod 543 is connected to the collar 541, and the collar 541 is connected to the upper left push rod 512 and the upper right push rod 522 through the connecting rod 55. Therefore, when the upper left push rod 512 and the upper right push rod 522 move up and down, the collar 541 is driven to slide along the lower left push rod 511 and the lower right push rod 521 through the connecting rod 55, thereby causing the U-shaped support rod 543 to move up and down. The design is ingenious.

[0042] like Figures 9 to 11 As shown, the mounting base 542 includes a fixed base 5421 disposed on a collar 541. The fixed base 5421 has multiple positioning teeth 544 along its circumference. The lower end of the U-shaped support rod 543 is connected to a movable base 5422 that can rotate relative to the fixed base 5421. The movable base 5422 has a positioning groove 545 along its circumference that engages with the positioning teeth 544 to allow the U-shaped support rod 543 to stop at the desired position. Through the engagement of the positioning groove 545 and the positioning teeth 544, when force is applied to the U-shaped support rod 543, the U-shaped support rod 543 can be rotated, unfolded, folded, or positioned by the pressure of the contact surfaces of the positioning groove 545 and the positioning teeth 544, making the unfolding or folding of the canopy tarpaulin 59 convenient and quick.

[0043] like Figure 11 As shown, the upper end of the connecting rod 55 is also provided with a transverse rod 58 that can support the backrest pocket 61.

[0044] like Figure 1 and Figure 12 As shown, U-shaped handlebars 56 are detachably connected to the lower left push rod 511 and the lower right push rod 521. The U-shaped handlebars 56 have T-shaped connectors (not shown) at both ends. The lower left push rod 511 and the lower right push rod 521 have T-shaped connectors 57 that can be inserted into the connectors. When an adult pushes the vehicle, the U-shaped handlebars are easy for children to grip, ensuring safety. When a child rides the vehicle independently, the U-shaped handlebars can be removed.

[0045] like Figure 4 and Figure 7 As shown, the connecting seat 21 is provided with a locking groove 91, and the main frame 1 is provided with a locking pin 92 that can slide inside and engage or disengage from the locking groove 91. The rear end of the main frame 1 is provided with an operating part 93 that can be gripped by a hand and slid relative to the main frame 1. The rear end of the main frame 1 is provided with an annular structure 94 that can be inserted into by a finger. The operating part 93 is located inside the annular structure 94. A cable (not shown in the figure) is provided between the operating part 93 and the locking pin 92, which can pull the locking pin 92 to disengage from the locking groove 91 when the operating part 93 is gripped. The main frame 1 is also provided with a first return spring 95 that can push the locking pin 92 to reset. A pin lock is provided between the rotating part 71 and the main frame 1 to lock the two. The main frame 1 and above the operating part 93 is provided with a button 96 that can be pressed by the thumb to unlock the pin lock when the hand grips the operating part 93. When the children's tricycle needs to be folded, fingers other than the thumb should be inserted upwards through the ring structure 94 and grasp the operating part 93. At this time, the operating part 93 pulls the locking pin 92 out of the locking groove 91 via a cable. Simultaneously, the thumb can be used to press the button 96, thereby unlocking the latch lock. Therefore, the unlocking operation is very convenient and quick, achieving simultaneous unlocking of the push rod assembly 5 and the steering assembly 2. The latch lock can adopt a traditional latching structure with a latching hole and a latching pin, which will not be described in detail here.

[0046] like Figure 12 As shown, the seat 4 is provided with a movable plate 41 that can move outward to extend the front and rear length of the seat 4. When the movable plate 41 moves outward, the front and rear length of the seat 4 is extended, so that the child can lie down and sleep in the tricycle. When it is not necessary to lie down, the movable plate 41 can be folded into the seat 4.
