DETAILED DESCRIPTION

[0055] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0056] Example:

[0057] As shown in Figures 1-7, the flip locking mechanism includes a locking component 7, which is arranged between the bucket mechanism 100 and the vehicle body 1. The locking component 7 is used to move the bucket mechanism 100 away from the vehicle body 1 when flipping, unlock the bucket mechanism 100, and lock the bucket mechanism 100 when the bucket mechanism 100 is placed on the vehicle body 1; a transmission component 8, which is connected to the locking component 7 to lock or unlock the bucket mechanism 100; an unlocking component 9, which is assembled on the vehicle body 1 and is used to unlock the bucket mechanism 100 from the locking component 7; the present invention can lock or unlock the bucket mechanism and the vehicle body by setting a flip locking mechanism, which is more stable than the existing shaft connection, has a simple structure, and is easy to assemble.

[0058] When the locking cam 73 is in the unlocked position, the locking cam 73 is in the unlocked position, and the locking cam 73 is in the unlocked position, so that the locking cam 73 can be unlocked and locked.

[0059] As shown in FIG1-2 , the transmission component 8 includes a transmission belt 80 , one end of the transmission belt 80 is connected to the locking connection portion 73 of the locking component 7 , and the other end of the transmission belt 80 is connected to the unlocking component 9 .

[0060] A limit block is provided at the end of the transmission belt 80 near the U-shaped groove 14, and the outer diameter of the limit block is larger than the notch size of the U-shaped groove 14. In this way, during use, the limit block is built into the U-shaped groove 14, and the transmission belt 80 can drive the locking connection part 73 to rotate. The locking connection part 73 includes a connecting plate 12 and a locking plate 13 fixed to the bottom of the connecting plate 12; a U-shaped groove 14 is formed on the locking plate 13, and one end of the transmission belt 80 is connected to the U-shaped groove 14, and a support block 15 connected to the spring 75 is fixed at the front end of the locking plate 13.

[0061] Specifically, as shown in FIG. 2 , a guide plate 16 is fixedly provided at the front end of the positioning plate 70 close to the U-shaped groove 14 , and a guide groove 17 for the transmission belt 80 to pass through is formed at the bottom of the guide plate 16 .

[0062] The guide plate 16 and guide groove 17 can guide the transmission belt 80, making the extension between the transmission belt 80 and the U-shaped groove 14 smoother, thereby ensuring that the unlocking component 9 is more convenient and safer to operate the transmission belt 80 during use.

[0063] The positioning groove 72 has a trumpet-shaped opening, and the bottom of the positioning groove 72 has a U-shaped structure. Setting the positioning groove 72 as a trumpet-shaped opening increases the contact area between the top of the positioning groove 72 and the mounting rod 27 during use, which facilitates the mounting rod 27 at the bottom of the dump bucket 2 to extend into the positioning groove 72 more quickly, thereby improving the assembly efficiency between the two. At the same time, the bottom of the positioning groove 72 has a U-shaped structure. The inner diameter of the U-shaped structure is the same as the outer diameter of the mounting rod 27, which avoids the mounting rod 27 located in the positioning groove 72 from shaking, making the entire stroller safer to use.

[0064] As shown in Figures 4-6, the unlocking component 9 includes a base 90 fixed on the vehicle body 1, a slide groove 91 is formed on the base 90, a slider 92 is slidably connected to the slide groove 91, the slider 92 is connected to one end of the transmission belt 80, and a sliding box 93 is assembled on the slider 92; the sliding box 93 has a mounting hole 19 formed at one end near the slider 92, the slider 92 is located in the sliding box 93, and its transmission belt 80 extends through the mounting hole 19, and a limiting column 95 is fixed along its length direction at the end of the sliding box 93 away from the mounting hole 19, and a limiting spring 96 is sleeved on the limiting column 95, and the limiting spring 96 is located on the positioning column 97 of the base 90.

[0065] A shift block 94 is fixedly provided on the top of the sliding box 93; the sliding box 93 is driven to move along the length direction of the base 90 by the shift block 94, so as to lock or open the dump bucket mechanism 100; correspondingly, a limit groove 11 adapted to the shift block 94 is formed on the vehicle body 1; the shift block 94 extends out of the limit groove 11 and moves back and forth along the limit groove 11, and the shift block 94 can be shifted from the first position L1 to the second position L2, and the shift block 94 is located in the limit groove 11 when the first position L1 and the second position L2 are both located. When the shift block 94 is in the first position L1, the locking portion 74 is located in the mounting groove 72 of the locking component 7, and when the shift block 94 is shifted from the first position L1 to the second position L2, the locking portion 74 disengages from the mounting groove 72 of the locking component 7, and the dump bucket mechanism 100 can be freely flipped.

[0066] 14 , in this embodiment, the first position L1 is a locked state, and the second position L2 is an unlocked state.

[0067] The unlocking component 9 also includes a limiting mechanism 40 for limiting the sliding of the sliding box 93 on the vehicle body 1. The sliding box 93 is formed with an assembly groove 98 that is compatible with the limiting mechanism 40.

[0069] In this embodiment, when the shift block 94 is in the second position L2, the limit button 41, through the elastic force of the limit spring 42, causes the limit button 41 of the limit mechanism 40 to extend out of the assembly slot 98, which is used to lock the shift block 94 and prevent the shift block 94 from moving. At this time, the bucket mechanism 100 is in a free flipping state, and the limit button 41 is pressed so that the limit button 41 is embedded in the assembly slot 98. At this time, the shift block 94 can be moved from the second position L2 to the first position L1, and the top of the limit button 41 abuts against the top of the sliding box 93, and the locking portion 74 is located in the mounting slot 72 of the locking component 7.

[0070] When the shift block 94 is moved from the first position L1 to the second position L2, the locking portion 74 disengages from the mounting groove 72 of the locking component 7, and the limit button 41 resting on the top of the sliding box 93 moves into the assembly groove 98, and is used to lock the sliding box 93 on the vehicle body 1 through the elastic force of the limit spring 42.

[0071] By providing the limiting mechanism 40 , it is possible to prevent children from making incorrect operations during use, thereby preventing damage to the tipping mechanism and thereby extending the service life of the entire baby stroller.

By flipping the locking mechanism, the dump bucket 2 can be locked to the vehicle body 1.

[0075] In this embodiment, two groups of crank assemblies 5 are provided, and the two groups of crank assemblies 5 are assembled on both sides of the electric gear assembly 4; with this arrangement, the drive shaft of the electric gear assembly 4 passes through the two groups of crank assemblies 5 respectively, and drives the crank assemblies 5 to rotate, making the process of driving the tipping bucket 2 to flip more stable and safer.

[0076] Among them, the electric gear assembly 4 is built into the vehicle body 1 and connected to the electric control component; the electric control component is a common button-type or push-rod-type control component, which is mainly used to start the motor and drive the electric gear set to rotate.
