[0075] The child stroller is a very common child walking tool, in order to increase the safety in use, the child stroller is usually provided with a brake mechanism, when the child stroller is in the open state and is not pushed, the brake mechanism can brake the wheels of the child stroller, to prevent the child stroller from moving by itself.

[0076] Since the brake mechanism generally adopts a foot brake, the brake mechanism is usually arranged at a position close to the ground, which easily causes the dirt on the ground to enter the connecting gap of the brake mechanism. Since the connecting gap of the brake mechanism is not convenient to clean, over time, the excessive dirt will accumulate in the brake mechanism, which easily causes the brake mechanism to be not sensitive in braking or even to be stuck.

[0077] To solve the technical problem that the dirt easily enters the brake mechanism, over time, the brake mechanism is not sensitive in braking or even stuck, an embodiment of the present application provides a brake mechanism for a child stroller, which comprises a rotating shaft 100, a pedal assembly 200 and a first connecting seat 300. Figures 1 to 8 The pedal assembly 200 comprises a driving part 210 sleeved on the rotating shaft 100, and the driving part 210 is configured to rotate relative to the rotating shaft 100 around the axis direction of the rotating shaft 100. The driving part 210 has a first connecting side along the axis direction of the rotating shaft 100, and the first connecting side is provided with a first blocking part 211. The first connecting seat 300 is connected to the rotating shaft 100 and is arranged on the first connecting side. The side of the first connecting seat 300 close to the first blocking part 211 is provided with a second blocking part 310, which is sleeved in or out of the first blocking part 211 to realize the sealed connection between the first connecting seat 300 and the driving part 210. The driving part 210 is provided with a first protruding part 213 close to the first connecting seat 300, which is in contact with or spaced apart from the outer peripheral wall of the first blocking part 211 or the second blocking part 310 along the radial direction of the rotating shaft 100.

[0078] Specifically, in the embodiment, the two ends of the rotating shaft 100 can be connected to a wheel set, and the driving part 210 sleeved on the rotating shaft 100 can be rotated to realize the braking or unlocking of the wheel set. For example, the pedal assembly 200 can comprise a foot pedal 220 connected to the driving part 210, and the user can rotate the driving part 210 relative to the rotating shaft 100 around the axis direction of the rotating shaft 100 by stepping on the foot pedal 220.

[0079] The first connecting side of the driving part 210 is provided with a first connecting seat 300, the side close to the first connecting seat 300 of the driving part 210 is provided with a first blocking part 211, the side close to the driving part 210 of the first connecting seat 300 is provided with a second blocking part 310, the second blocking part 310 can be sleeved in the inside of the first blocking part 211, or the second blocking part 310 can be sleeved outside the first blocking part 211, through the cooperation between the first blocking part 211 and the second blocking part 310, the sealed connection between the driving part 210 and the first connecting seat 300 can be realized, and then the connection gap between the driving part 210 and the rotating shaft 100 can be reduced or eliminated. By adopting such structure, since the outside wall of the second blocking part 310 is tightly fitted with the inside wall of the first blocking part 211, or the inside wall of the second blocking part 310 is tightly fitted with the outside wall of the first blocking part 211, the entry of the sand and other impurities into the inside of the driving part 210 is hindered, so that there is no excessive sand and other impurities accumulated in the inside of the driving part 210, the driving part 210 is prevented from being blocked by the sand and other impurities, and the phenomenon of the driving part 210 being stuck is caused, and the normal use of the brake mechanism is affected.

[0080] Further, when the child stroller is braked or unlocked by using the brake mechanism, that is, when the driving part 210 rotates relative to the rotating shaft 100 around the axis direction of the rotating shaft 100, the driving part 210 drives the first protruding part 213 to rotate, at this time, the first protruding part 213 scrapes off the sand and other impurities attached to the outer peripheral wall of the first blocking part 211 or the outer peripheral wall of the second blocking part 310, and the self-cleaning of the first blocking part 211 or the second blocking part 310 is realized.

[0081] It should be noted that when the second blocking part 310 is sleeved in the first blocking part 211, when the driving part 210 drives the first protruding part 213 to rotate, the first protruding part 213 scrapes off the sand and other impurities attached to the outer peripheral wall of the first blocking part 211, and the self-cleaning of the first blocking part 211 is realized. When the second blocking part 310 is sleeved outside the first blocking part 211, when the driving part 210 drives the first protruding part 213 to rotate, the first protruding part 213 scrapes off the sand and other impurities attached to the outer peripheral wall of the second blocking part 310, and the self-cleaning of the second blocking part 310 is realized.

[0082] It can be understood that the first blocking part 211 and the second blocking part 310 are gap-fitted, so as to prevent the clamping between the first blocking part 211 and the second blocking part 310 from being too tight, and to ensure that the driving part 210 can rotate relative to the rotating shaft 100 around the axis direction of the rotating shaft 100.

[0083] In some embodiments, referring to Figures 1 to 8The driving part 210 has a second connecting side opposite to the first connecting side along the axial direction of the rotating shaft 100, and the driving part 210 is provided with a third blocking part 212 at the second connecting side. The brake mechanism comprises a second connecting seat 400 connected to the rotating shaft 100, which is arranged at the second connecting side, and the second connecting seat 400 is provided with a fourth blocking part 410 on the side close to the third blocking part 212, which is sleeved inside or outside the third blocking part 212 to realize the sealed connection between the second connecting seat 400 and the driving part 210. Wherein, the driving part 210 is provided with a second protruding part 214 towards the second connecting seat 400, which is in contact or spaced apart along the radial direction of the rotating shaft 100 and the outer wall of the third blocking part 212 or the fourth blocking part 410.

[0084] Specifically, in the embodiment, the second connecting side of the driving part 210 is provided with the second connecting seat 400, the side close to the second connecting seat 400 of the driving part 210 is provided with the third blocking part 212, the side close to the driving part 210 of the second connecting seat 400 is provided with the fourth blocking part 410, which can be sleeved inside the third blocking part 212, or the fourth blocking part 410 can also be sleeved outside the third blocking part 212, and the sealed connection between the driving part 210 and the second connecting seat 400 can be realized through the cooperation between the third blocking part 212 and the fourth blocking part 410, thereby reducing or eliminating the connection gap between the driving part 210 and the rotating shaft 100. With such a structure, since the outer wall of the fourth blocking part 410 closely abuts the inner wall of the third blocking part 212, or the inner wall of the fourth blocking part 410 closely abuts the outer wall of the third blocking part 212, it will hinder the entry of sand and other impurities into the interior of the driving part 210, so that there is no excessive accumulation of sand and other impurities in the interior of the driving part 210, preventing the driving part 210 from rotating sensitively due to the blockage of sand and other impurities, or even causing the driving part 210 to be stuck, affecting the normal use of the brake mechanism.

[0085] Further, when the brake mechanism is used to brake or unlock the child stroller, i.e. the driving part 210 rotates relative to the rotating shaft 100 along the axial direction of the rotating shaft 100, the driving part 210 will drive the second protruding part 214 to rotate, and at this time the second protruding part 214 will scrape off the sand and other impurities attached to the outer wall of the third blocking part 212 or the outer wall of the fourth blocking part 410, realizing the self-cleaning of the third blocking part 212 or the fourth blocking part 410.

[0086] It should be noted that when the fourth blocking part 410 is sleeved in the third blocking part 212, when the driving part 210 drives the second protruding part 214 to rotate, the second protruding part 214 can scrape off the silt and other impurities attached to the outer peripheral wall of the third blocking part 212, thereby realizing self-cleaning of the third blocking part 212. When the fourth blocking part 410 is sleeved outside the third blocking part 212, when the driving part 210 drives the second protruding part 214 to rotate, the second protruding part 214 can scrape off the silt and other impurities attached to the outer peripheral wall of the fourth blocking part 410, thereby realizing self-cleaning of the fourth blocking part 410.

[0087] It can be understood that the third blocking part 212 and the fourth blocking part 410 are gap-fitted to prevent the third blocking part 212 and the fourth blocking part 410 from being too tightly clamped, and to ensure that the driving part 210 can rotate relative to the rotating shaft 100 about the axis direction of the rotating shaft 100.

[0088] With reference to the above-mentioned embodiments, by providing the first connecting seat 300 on the first connecting side of the driving part 210, and the first blocking part 211 of the driving part 210 and the second blocking part 310 of the first connecting seat 300 are sleeved with each other, the sealed connection between the driving part 210 and the first connecting seat 300 is realized. At the same time, by providing the second connecting seat 400 on the second connecting side of the driving part 210, and the third blocking part 212 of the driving part 210 and the fourth blocking part 410 of the second connecting seat 400 are sleeved with each other, the sealed connection between the driving part 210 and the second connecting seat 400 is realized. By adopting the above structure, the overall sealing effect of the driving part 210 can be improved, and the driving part 210 can realize better silt invasion prevention effect.

[0089] In some embodiments, with reference to Figure 6 , the driving part 210 is provided with a first recess 215 at the first protruding part 213, and the first recess 215 is used to accommodate the first connecting seat 300. The driving part 210 is provided with a second recess 216 at the second protruding part 214, and the second recess 216 is used to accommodate the second connecting seat 400.

[0090] Specifically, in the present embodiment, when the second blocking part 310 is sleeved outside the first blocking part 211, the first connecting seat 300 is clamped into the first recess 215, and the position of the first connecting seat 300 can be avoided. By adopting such structure, on the one hand, it is beneficial to the contact or interval arrangement of the first protruding part 213 and the outer peripheral wall of the second blocking part 310 of the first connecting seat 300, thereby facilitating the self-cleaning effect of the first protruding part 213 on the second blocking part 310. On the other hand, it is beneficial to ensure the compactness of the structure of the brake mechanism.

[0091] Similarly, when the fourth blocking part 410 is sleeved outside the third blocking part 212, the second connecting seat 400 is clamped into the second recessed part 216, and the position of the second connecting seat 400 can be avoided. With such a structure, on the one hand, the second protruding part 214 and the outer peripheral wall of the fourth blocking part 410 of the second connecting seat 400 are in contact or are spaced apart, thereby facilitating the self-cleaning effect of the second protruding part 214 on the fourth blocking part 410. On the other hand, it is beneficial to ensure the compactness of the structure of the brake mechanism.

[0092] In some embodiments, with reference to Figures 1 to 8 , along the axis direction of the rotating shaft 100, the driving part 210 is arranged at the middle position of the rotating shaft 100.

[0093] Specifically, in the present embodiment, the driving part 210 can be connected with the foot pedal part 220, so that the user can drive the driving part 210 to rotate by stepping on the foot pedal part 220. Since different users may have different usage habits, for example, some users may be used to stepping on the foot pedal part 220 with the left foot, and some users may be used to stepping on the foot pedal part 220 with the right foot. By arranging the driving part 210 (i.e., arranging the pedal assembly 200 at the middle position of the rotating shaft 100) at the middle position of the rotating shaft 100 (because when pushing the stroller, the user is generally standing at the middle position of the stroller), it can adapt to different usage habits of users, and ensure that it is convenient for the user to use the left foot to step on the foot pedal part 220 to drive the driving part 210 to rotate, and at the same time, it is also convenient for the user to use the right foot to step on the foot pedal part 220 to drive the driving part 210 to rotate, thereby facilitating the user to use the present brake mechanism to brake or unlock the stroller.

[0094] In some embodiments, with reference to Figure 5 and Figure 7 , the rotating shaft 100 is provided with a limiting slot 110, the driving part 210 is provided with a connecting hole, and a connecting piece 120 is arranged in the limiting slot 110 and the connecting hole to connect the driving part 210 to the rotating shaft 100. For example, the connecting piece 120 can be a pin.

[0095] It should be noted that the connecting piece 120 is movably connected between the limiting slot 110 and the rotating shaft 100, that is, the connecting piece 120 can move relatively in the limiting slot 110, and the connecting piece 120 is fixedly connected with the driving part 210 through the connecting hole, that is, the connecting piece 120 can drive the driving part 210 to move when moving.

[0096] Specifically, in the present embodiment, the driving part 210 can be connected with the foot pedal part 220, so as to facilitate the user to realize the rotational driving of the driving part 210 by stepping the foot pedal part 220. When the user steps the foot pedal part 220, the connecting part 120 will move in the limiting groove 110 after being forced, and the connecting part 120 will drive the driving part 210 to rotate in the positive direction relative to the rotating shaft 100 around the axis direction of the rotating shaft 100, so as to realize the braking operation of the child stroller by using the present brake mechanism. Alternatively, the connecting part 120 will drive the driving part 210 to rotate in the reverse direction relative to the rotating shaft 100 around the axis direction of the rotating shaft 100, so as to realize the unlocking operation of the child stroller by using the present brake mechanism.

[0097] In some embodiments, referring to Figure 7 and Figure 8 , the brake mechanism comprises a first driving shaft 500, a second driving shaft 600, a first wheel 700 and a second wheel 800, the driving part 210 is provided with a first pushing slope 217 on the side close to the first connecting seat 300, one end of the first driving shaft 500 abuts against the first pushing slope 217, the first driving shaft 500 is provided with a first locking pin 510 at the end away from the first pushing slope 217, the driving part 210 is provided with a second pushing slope 218 on the side close to the second connecting seat 400, one end of the second driving shaft 600 abuts against the second pushing slope 218, the second driving shaft 600 is provided with a second locking pin 610 at the end away from the second pushing slope 218, the first wheel 700 is provided with a plurality of first locking holes 710, and the second wheel 800 is provided with a plurality of second locking holes 810. Wherein, the first driving shaft 500 is driven by the first pushing slope 217, so as to make the first locking pin 510 inserted into the first locking hole 710, and realize the braking of the first wheel 700; the second driving shaft 600 is driven by the second pushing slope 218, so as to make the second locking pin 610 inserted into the second locking hole 810, and realize the braking of the second wheel 800.

[0098] Specifically, in the embodiment, the driving part 210 can be connected with the pedal part 220, so as to facilitate the user to realize the rotational driving of the driving part 210 by stepping on the pedal part 220. When the first wheel 700 is braked, the user can step on the pedal part 220, at this time, the pedal part 220 drives the driving part 210 to rotate relative to the rotating shaft 100 around the axis direction of the rotating shaft 100, and when the driving part 210 rotates, the first pushing inclined surface 217 also rotates (as the name implies, the first pushing inclined surface 217 is an inclined pushing surface). Since the first pushing inclined surface 217 abuts against one end of the first driving shaft 500, when the first pushing inclined surface 217 rotates, a pushing force is applied to the first driving shaft 500, so that the first driving shaft 500 is elongated away from the driving part 210, so as to drive the first locking pin 510 to extend into the first locking hole 710, thereby realizing the braking operation of the first wheel 700.

[0099] It can be understood that a plurality of first locking holes 710 can be arranged around the circumference of the first wheel 700, and the first locking pin 510 extends into any one of the first locking holes 710 to realize the braking operation of the first wheel 700.

[0100] It should be noted that, with reference to the above embodiment, the first driving shaft 500 can be arranged in the first connecting seat 300 to realize the positioning connection of the first driving shaft 500.

[0101] Similarly, when the second wheel 800 is braked, the user can step on the pedal part 220, at this time, the pedal part 220 drives the driving part 210 to rotate relative to the rotating shaft 100 around the axis direction of the rotating shaft 100, and when the driving part 210 rotates, the second pushing inclined surface 218 also rotates (as the name implies, the second pushing inclined surface 218 is an inclined pushing surface). Since the second pushing inclined surface 218 abuts against one end of the second driving shaft 600, when the second pushing inclined surface 218 rotates, a pushing force is applied to the second driving shaft 600, so that the second driving shaft 600 is elongated away from the driving part 210, so as to drive the second locking pin 610 to extend into the second locking hole 810, thereby realizing the braking operation of the second wheel 800.

[0102] It can be understood that a plurality of second locking holes 810 can be arranged around the circumference of the second wheel 800, and the second locking pin 610 extends into any one of the second locking holes 810 to realize the braking operation of the second wheel 800.

[0103] It should be noted that, with reference to the above embodiment, the second driving shaft 600 can be arranged in the second connecting seat 400 to realize the positioning connection of the second driving shaft 600.

[0104] Further, with reference to Figure 1 andFigure 2 The first wheel 700 and the second wheel 800 can be respectively connected to two ends of the rotating shaft 100. The end of the rotating shaft 100 close to the first wheel 700 can be provided with a first pivot seat 130, and the first pivot seat 130 can be provided with a first pivot hole 131. The first wheel 700 can be provided with a first pivot shaft 720. By inserting the first pivot shaft 720 into the first pivot hole 131, the connection between the first wheel 700 and the end of the rotating shaft 100 can be achieved. Similarly, the end of the rotating shaft 100 close to the second wheel 800 can be provided with a second pivot seat 140, and the second pivot seat 140 can be provided with a second pivot hole 141. The second wheel 800 can be provided with a second pivot shaft 820. By inserting the second pivot shaft 820 into the second pivot hole 141, the connection between the second wheel 800 and the end of the rotating shaft 100 can be achieved.

[0105] In some embodiments, referring to Figure 5 , Figure 7 and Figure 8 , the first locking pin 510 is connected with a first elastic part 520, and the first elastic part 520 is configured to drive the first locking pin 510 to move away from the first locking hole 710, so that the first locking pin 510 is separated from the first locking hole 710, and the brake of the first wheel 700 is released. The second locking pin 610 is connected with a second elastic part 620, and the second elastic part 620 is configured to drive the second locking pin 610 to move away from the second locking hole 810, so that the second locking pin 610 is separated from the second locking hole 810, and the brake of the second wheel 800 is released.

[0106] Specifically, in the embodiment, when the first wheel 700 is in the braking state, the first driving shaft 500 drives the first locking pin 510 to extend into the first locking hole 710, and at the same time, the first elastic part 520 is compressed. When the first wheel 700 is unlocked, the user can step on the pedal part 220 again, and at this time, the pedal part 220 drives the driving part 210 to rotate in the opposite direction relative to the rotating shaft 100. When the driving part 210 rotates in the opposite direction, the first pushing inclined surface 217 also rotates in the opposite direction. When the first pushing inclined surface 217 rotates in the opposite direction, the pushing force applied to the first driving shaft 500 is removed (in other words, when the first pushing inclined surface 217 rotates in the opposite direction, the inclined surface no longer presses the end of the first driving shaft 500), that is, the first elastic part 520 is no longer compressed. At this time, the first elastic part 520 has a tendency to recover the elastic deformation. When the first elastic part 520 recovers the elastic deformation, it drives the first locking pin 510 to move away from the first locking hole 710, so that the first locking pin 510 is no longer clamped in the first locking hole 710, thereby achieving the unlocking operation of the first wheel 700.

[0107] Similarly, when the second wheel 800 is in the braking state, the second driving shaft 600 drives the second locking pin 610 to extend into the second locking hole 810, at the same time, the second elastic part 620 is compressed, when the second wheel 800 is unlocked, the user can step on the pedal part 220 again, at this time, the pedal part 220 drives the driving part 210 to rotate reversely relative to the rotating shaft 100 along the axis direction of the rotating shaft 100, when the driving part 210 rotates reversely, the second pushing inclined surface 218 also rotates reversely, when the second pushing inclined surface 218 rotates reversely, the pushing force applied to the second driving shaft 600 is removed (in other words, when the second pushing inclined surface 218 rotates reversely, the inclined surface no longer presses the end of the second driving shaft 600), that is, the second elastic part 620 is no longer pressed, at this time, the second elastic part 620 has a tendency to restore the elastic deformation, when the second elastic part 620 restores the elastic deformation, the second locking pin 610 is driven to move away from the second locking hole 810, so that the second locking pin 610 is no longer clamped in the second locking hole 810, thereby realizing the unlocking operation of the second wheel 800.

[0108] In some embodiments, referring to Figure 7 and Figure 8 , the first blocking part 211 is provided with a first supporting part 2111, and the third blocking part 212 is provided with a second supporting part 2121. Exemplarily, for example, the first supporting part 2111 can be a reinforcing rib structure, and the second supporting part 2121 can be a reinforcing rib structure.

[0109] Specifically, in the embodiment, the first supporting part 2111 is beneficial to improve the structural strength of the first blocking part 211, prevent the first blocking part 211 from being easily deformed after being stressed (since the driving part 210 will rotate relative to the rotating shaft 100, the first blocking part 211 will at least be subjected to a rotating force during the rotation of the driving part 210), thereby being beneficial to improve the connection strength between the first blocking part 211 and the second blocking part 310, avoid the connection gap between the first blocking part 211 and the second blocking part 310 from being increased, and effectively prevent impurities such as sand from entering the inside of the driving part 210.

[0110] Similarly, the second supporting part 2121 is beneficial to improve the structural strength of the third blocking part 212, prevent the third blocking part 212 from being easily deformed after being stressed (since the driving part 210 will rotate relative to the rotating shaft 100, the third blocking part 212 will at least be subjected to a rotating force during the rotation of the driving part 210), thereby being beneficial to improve the connection strength between the third blocking part 212 and the fourth blocking part 410, avoid the connection gap between the third blocking part 212 and the fourth blocking part 410 from being increased, and effectively prevent impurities such as sand from entering the inside of the driving part 210.

[0111] In some embodiments, the second blocking part 310 is provided with a first clamping groove, and the first blocking part 211 is clamped in the first clamping groove; the fourth blocking part 410 is provided with a second clamping groove, and the third blocking part 212 is clamped in the second clamping groove.

[0112] Specifically, in the embodiment, by clamping the first blocking part 211 in the first clamping groove, the connection stability between the first blocking part 211 and the second blocking part 310 is improved, and by clamping the third blocking part 212 in the second clamping groove, the connection stability between the third blocking part 212 and the fourth blocking part 410 is improved.

[0113] It should be noted that the first blocking part 211 and the first clamping groove are in clearance fit, and the third blocking part 212 and the second clamping groove are in clearance fit, so as to ensure that the driving part 210 can rotate relative to the rotating shaft 100 around the axis direction of the rotating shaft 100, and realize the braking or unlocking of the brake mechanism on the child stroller.

[0114] Correspondingly, another embodiment of the present application also provides a child stroller, which refers to Figure 9 The child stroller comprises the brake mechanism in any of the above embodiments.

[0115] Specifically, in the embodiment, the child stroller applying the brake mechanism can avoid the entry of impurities such as sand into the brake mechanism of the child stroller, so as to ensure the brake sensitivity and braking effect of the child stroller.
