[0032] Embodiments of the present application are described in detail below with reference to the accompanying drawings, wherein the same or like reference numerals represent the same or like elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary only, and are intended to explain the present application, and should not be understood as a limitation of the present application.

[0033] Reference is made below to Figures 1-7 the brake assembly 100 of the stroller according to the embodiments of the present application and the stroller.

[0034] As Figures 1-2 shown, the brake assembly 100 of the stroller according to the first aspect of the present application, the brake assembly 100 comprises: a mounting seat 10, a brake mechanism 20 and a shielding part 30.

[0035] The mounting seat 10 is arranged on the axle 200, and the mounting seat 10 is provided with a mounting cavity 11 having an open mouth 12; the brake mechanism 20 is rotatably arranged on the axle 200 and located in the mounting cavity 11; the shielding part 30 is formed on the mounting seat 10 and / or the brake mechanism 20; the open mouth 12 is located on the periphery of the mounting cavity 11, the open mouth 12 defines the upper and lower stop points of the movement stroke of the brake mechanism 20, when the brake mechanism 20 is located at the upper stop point, the brake mechanism 20 is in the release position, when the brake mechanism 20 is located at the lower stop point, the brake mechanism 20 is in the locking position, and when the brake mechanism 20 is in the release position, the shielding part 30 is used to shield the open mouth 12 above the open mouth 12.

[0036] Specifically, the mounting base 10 is arranged on the axle 200, the brake mechanism 20 is arranged in the mounting cavity 11 of the mounting base 10 and rotatably connected with the axle 200, the brake mechanism 20 can move between the upper dead point and the lower dead point of the open hole 12 to realize the locking and unlocking of the stroller, when the brake mechanism 20 is located at the lower dead point, the brake mechanism 20 is in the locked position, at this time, the stroller is in the locked state, and the wheel 300 cannot rotate, when the brake mechanism 20 is located at the upper dead point, the brake mechanism 20 is in the unlocked position, at this time, the stroller is in the unlocked state, and the wheel 300 can rotate freely, meanwhile, the shielding part 30 can shield the open hole 12 above the open hole 12, and the brake mechanism 20 is located at the upper dead point, and the brake mechanism 20 abuts against the upper end of the open hole 12.

[0037] It can be understood that the shielding part 30 can be arranged in multiple schemes, for example, the shielding part 30 is formed on the mounting base 10, the shielding part 30 is formed on the brake mechanism 20, or the shielding part 30 is arranged on both the mounting base 10 and the brake mechanism 20.

[0038] If the shielding part 30 is formed on the mounting base 10, when the brake mechanism 20 is in the unlocked position, the brake mechanism 20 is located at the upper dead point, the brake mechanism 20 has a gap with the upper edge of the open hole 12, the shielding part 30 shields the open hole 12 above the open hole 12, at this time, the shielding part 30 can shield the gap between the brake mechanism 20 and the open hole 12 to prevent sundries such as mud from entering the mounting cavity 11.

[0039] If the shielding part 30 is formed on the brake mechanism 20, when the brake mechanism 20 is in the unlocked position, the brake mechanism 20 is located at the upper dead point, the brake mechanism 20 has a gap with the upper edge of the open hole 12, at this time, the shielding part 30 can be formed on the outside of the gap, thereby preventing sundries such as mud from entering the mounting cavity 11 from the outside of the brake mechanism 20.

[0040] If the shielding part 30 is arranged on both the mounting base 10 and the brake mechanism 20, when the brake mechanism 20 is in the unlocked position, the brake mechanism 20 is located at the upper dead point, the shielding part 30 on the brake mechanism 20 can be in contact with the shielding part 30 on the mounting base 10 to form a sealing fit, thereby preventing sundries such as mud from entering the mounting cavity 11.

[0041] According to the brake assembly 100 of the stroller of the first aspect of the present application, the shielding part 30 shields the upper part of the open hole 12, which can block sundries, and can prevent sundries from entering the mounting cavity 11 during use of the stroller, prevent the brake from being stuck, and improve the stability of the brake assembly 100.

[0042] As Figure 2As shown, in some embodiments, the shielding portion 30 includes a first shielding portion 31, which is located at the upper edge of the opening 12.

[0043] Specifically, when a baby stroller is in use, due to different usage environments, debris such as mud and sand on the road may be driven by the wheels 300 and enter the mounting cavity 11 while the stroller is moving, jamming the relevant mechanisms inside the brake assembly 100, thus preventing the stroller from braking properly. When the stroller is in the locked state, it is stationary, and the probability of debris such as mud and sand entering the mounting cavity 11 is relatively small. Therefore, it is necessary to focus on solving the sealing problem of the brake assembly 100 when it is in the unlocked position. By setting the first blocking part 31 on the upper edge of the open opening 12, when the brake mechanism 20 is in the unlocked state, the brake mechanism 20 is at its upper dead point. At this time, the first blocking part 31 can abut against the brake mechanism 20, thereby blocking debris such as mud and sand.

[0044] Therefore, when the brake mechanism 20 is in the unlocked position, it can block foreign objects from entering the mounting cavity 11, thereby improving the stability of the brake assembly 100.

[0045] like Figures 2-3 As shown, the braking mechanism 20 further includes a drive unit 21 and a pedal unit 22. The drive unit 21 and the pedal unit 22 are connected by a connecting arm 23. The drive unit 21 is disposed in the mounting cavity 11, and the pedal unit 22 is located outside the mounting cavity 11. In the unlocked position, the connecting arm 23 is located below the first blocking part 31.

[0046] Specifically, when locking the stroller, stepping on the pedal 22 rotates the drive unit 21 within the mounting cavity 11, thereby switching the brake mechanism 20 to the locked position. Conversely, stepping on the pedal 22 switches the brake mechanism 20 to the unlocked position. The connecting arm 23 connects the drive unit 21 to the pedal 22. When the brake mechanism 20 is in the unlocked position, it is at its upper dead point, and the connecting arm 23 is close to the upper edge of the opening 12. At this time, the connecting arm 23 is located below the first blocking part 31, which blocks the connecting arm 23, thus separating it from the pedal 22. Any debris on the pedal 22 is then blocked by the first blocking part 31.

[0047] This prevents debris on the pedal portion 22 from entering the mounting cavity 11, thereby improving the stability of the brake assembly 100.

[0048] like Figures 2-3 As shown, optionally, the shielding part 30 further includes a second shielding part 32, which is formed on the side of the connecting arm 23 facing the first shielding part 31.

[0049] Specifically, when the brake mechanism 20 is in the released position, the brake mechanism 20 is located at the upper dead point, the connecting arm 23 is close to the upper edge of the open hole 12, the first shielding part 31 is formed on the upper edge of the open hole 12, the second shielding part 32 is formed on the side of the connecting arm 23 facing the first shielding part 31, at this time, the first shielding part 31 can cooperate with the second shielding part 32 to form a sealed space in the mounting cavity 11, thereby improving the sealing performance of the mounting cavity 11 and preventing sundries from entering the mounting cavity 11. Thus, the sundries on the pedal part 22 can be shielded, and the stability of the brake assembly 100 is further improved.

[0050] It should be noted that the relative position relationship between the first shielding part 31 and the second shielding part 32 when the brake mechanism 20 is at the upper dead point is not specifically limited herein, for example, the first shielding part 31 can be located inside the second shielding part 32, the first shielding part 31 can also be located outside the second shielding part 32, and the first shielding part 31 can also abut against the second shielding part 32. When the first shielding part 31 is located inside or outside the second shielding part 32, a labyrinth sealing structure can be formed between the first shielding part 31 and the second shielding part 32, and the contact surface therebetween has a plurality of meandering bends. When sundries such as sand and dust move into the mounting cavity 11, the plurality of meandering bends can block the sundries, thereby further improving the stability of the brake assembly 100. When the first shielding part 31 abuts against the second shielding part 32, a sealing surface is formed therebetween, which also has the effect of blocking sundries. The arrangement can be made according to actual needs.

[0051] As shown in Figures 2-4 , further optionally, the second shielding part 32 is formed as a shielding protrusion, and the first shielding part 31 is provided with a receiving groove 311, and when the brake mechanism 20 is in the released position, the shielding protrusion extends into the receiving groove 311.

[0052] Specifically, the shielding protrusion extends into the receiving groove 311 to form a labyrinth sealing structure, and a plurality of meandering bends are formed between the shielding protrusion and the receiving groove 311. When sundries such as sand and dust enter the gap therebetween, the sundries can be blocked, thereby further preventing the sundries from entering the mounting cavity 11. Moreover, when the second shielding part 32 cooperates with the first shielding part 31, the brake mechanism 20 is in the released position, and the shielding protrusion extends into the receiving groove 311, which can also prevent the brake mechanism 20 from shaking during the travel of the stroller. Thus, the stability of the brake assembly 100 can be improved.

[0053] As shown in Figure 2 , Figures 4-5 , in some embodiments, the mounting seat 10 comprises a seat body 13 and a cover body 14, the seat body 13 and the cover body 14 define the mounting cavity 11, and the open hole 12 is formed in the seat body 13.

[0054] Specifically, the mounting base 10 is composed of the base body 13 and the cover body 14. When the brake assembly 100 is assembled, the driving part 21 of the brake mechanism 20 is first installed into the mounting cavity 11, the pedal part 22 is extended out of the mounting base 10 through the open port 12, and then the cover body 14 is connected and fixed with the base body 13 to form a sealed structure. In this way, by setting the mounting base 10 as a split structure, the assembly difficulty of the brake assembly 100 can be reduced.

[0055] It should be noted that the mounting mode of the base body 13 and the cover body 14 is not specifically limited herein, and the base body 13 and the cover body 14 can be connected by buckling, bolting, screwing or inserting, which can be set according to actual needs.

[0056] As shown in Figure 4 , further, the base body 13 is provided with a first shielding rib 131, which extends along the movement track of the brake mechanism 20 and is located on one side of the brake mechanism 20.

[0057] Specifically, the first shielding rib 131 provided on the base body 13 can provide shielding on one side of the brake mechanism 20. When the driving part 21 of the brake mechanism 20 is connected with the pedal part 22 through the connecting arm 23, the connecting arm 23 is located at the open port 12, so the first shielding rib 131 on the base body 13 can cooperate with the connecting arm 23 to shield the space on the side of the brake mechanism 20 close to the base body 13.

[0058] In this way, it can be prevented that sundries enter the mounting cavity 11 from the side of the brake mechanism 20, and the stability of the brake assembly 100 can be improved.

[0059] As shown in Figure 5 , further optionally, the cover body 14 is provided with a second shielding rib 141, which extends along the movement track of the brake mechanism 20 and is located on the other side of the brake mechanism 20.

[0060] Specifically, the second shielding rib 141 provided on the cover body 14 can provide shielding on the other side of the brake mechanism 20. When the driving part 21 of the brake mechanism 20 is connected with the pedal part 22 through the connecting arm 23, the connecting arm 23 is located at the open port 12, so the second shielding rib 141 on the cover body 14 can cooperate with the connecting arm 23 to shield the space on the side of the brake mechanism 20 close to the cover body 14.

[0061] In this way, it can be prevented that sundries enter the mounting cavity 11 from the side of the brake mechanism 20, and the stability of the brake assembly 100 can be improved.

[0062] As shown in Figures 6-7 , optionally, the first shielding rib 131 and the second shielding rib 141 are adjacent to the second shielding part 32 on the brake mechanism 20 relative to the mounting cavity 11.

[0063] Specifically, in the direction extending outward from the mounting cavity 11, there are in sequence the driving part 21 of the brake mechanism 20, the connecting arm 23, the first shielding rib 131 and the second shielding rib 141 located on both sides of the connecting arm 23, the second shielding part 32, and the pedal part 22. The second shielding part 32 is located outward of the first shielding rib 131 and the second shielding rib 141, and when the brake mechanism 20 is in the released position, the second shielding part 32 is inserted into the accommodating groove 311 of the first shielding part 31, and the first shielding rib 131 and the second shielding rib 141 are located inward of the two, so that the impurities such as sand can be blocked in multiple directions, preventing the impurities from entering the mounting cavity 11. Thus, the shielding effect of the impurities can be further improved, and the stability of the brake assembly 100 can be improved.

[0065] According to the stroller of the second aspect of the present application, by arranging the above brake assembly (100) on the stroller, the sealing performance of the brake of the stroller can be improved, and the reliability of the brake of the stroller is higher.
