Technical Field

[0001] The present application relates to the technical field of brakes, and particularly to a brake assembly and a children's vehicle. Background Art

[0002] A children's vehicle includes a brake assembly, and the brake assembly can lock and unlock a runner to meet the usage requirements of different application scenarios. In the prior art, the brake assembly includes a mounting seat, a locking member, and a driving member. The driving member can drive the locking member to move relative to the mounting seat to a locking position and an unlocking position. The driving member includes a first pushing portion and a second pushing portion. When the first pushing portion abuts against the locking member, the locking member can be in the locking position, and when the second pushing portion abuts against the locking member, the locking member can be in the unlocking position. However, when the locking member is in the locking position, affected by the movement of the runner or the vibration of the brake assembly, etc., the locking member may directly switch from the locking position where it abuts against the first pushing portion to the unlocking position where it abuts against the second pushing portion, resulting in accidental unlocking of the locking member, that is, the braking stability of the existing brake assembly is poor. Summary of the Utility Model

[0003] The main purpose of the present application is to propose a brake assembly and a children's vehicle, aiming to improve the braking stability of the brake assembly.

[0004] To achieve the above object, an embodiment of the first aspect of the present application proposes a brake assembly for braking a runner, the runner includes a locking hole, and the brake assembly includes:

[0005] A mounting seat;

[0006] A locking member, movably connected to the mounting seat, and the locking member can move relative to the mounting seat along a first direction;

[0007] A driving member, movably connected to one side of the mounting seat along the first direction, the driving member is configured to be able to move relative to the mounting seat to a locking position and an unlocking position, and during the movement of the driving member relative to the mounting seat, the driving member can drive the locking member to move relative to the mounting seat along the first direction. The driving member includes a first pushing portion and a second pushing portion. When the driving member moves to the locking position, the first pushing portion abuts against the locking member to make at least a part of the locking member extend into the locking hole. When the driving member moves to the unlocking position, the second pushing portion abuts against the locking member to make the locking member protrude out of the locking hole;

[0008] Wherein, a first protruding portion is provided between the first pushing portion and the second pushing portion, and along the first direction, the first protruding portion protrudes and extends towards the locking member.

[0009] In the above embodiment, the brake assembly includes a mounting seat, a locking member and a driving member. The driving member includes a first pushing portion and a second pushing portion. When the driving member moves to the locking position, the first pushing portion abuts the locking member so that the locking member at least partially extends into the locking hole. When the driving member moves to the unlocking position, the second pushing portion abuts the locking member so that the locking member is out of the locking hole. In the prior art, due to the influence of the movement of the rotating wheel or the vibration of the brake assembly, the locking member may directly switch from the locking position abutting the first pushing portion to the unlocking position abutting the second pushing portion, resulting in accidental release of the locking member, that is, the braking stability of the existing brake assembly is poor. In this solution, a first protrusion is provided between the first pushing portion and the second pushing portion, and the first protrusion extends toward the locking member along the first direction, that is, the first protrusion can prevent the locking member from directly switching from abutting with the first pushing portion to abutting with the second pushing portion, thereby reducing the situation where the locking member is accidentally released, and effectively improving the braking stability of the brake assembly. Compared with the solution in the prior art that the locking member moves smoothly from the first pushing part to the second pushing part, the locking member of the present solution needs to switch from the position abutting the first pushing part to the position abutting the second pushing part across the first protrusion. Since there is a height difference between the first protrusion and the first pushing part and the second pushing part, the present solution can provide strong feedback for the driving member during the switching of the movement position, thereby ensuring the accuracy of the switching operation of the driving member between the locking position and the releasing position.

[0074] Next, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present application.

[0075] The children's vehicle includes a brake assembly, and the brake assembly can lock and unlock the rotating wheel to meet the usage requirements of different application scenarios. In the prior art, the brake assembly includes a mounting seat, a locking member and a driving member. The driving member can drive the locking member to move relative to the mounting seat to a locking position and an unlocking position. The driving member includes a first pushing portion and a second pushing portion. The first pushing portion abuts against the locking member to make the locking member in the locking position, and the second pushing portion abuts against the locking member to make the locking member in the unlocking position. However, when the locking member is in the locking position, affected by the movement of the rotating wheel or the vibration of the brake assembly, etc., the locking member will directly switch from the locking position abutting against the first pushing portion to the unlocking position abutting against the second pushing portion, resulting in accidental unlocking of the locking member, that is, the braking stability of the existing brake assembly is poor.

[0076] In view of this, an embodiment of the first aspect of the present application provides a braking assembly 10, which is used to brake the rotating wheel 20 and can ensure the stability of braking. It should be noted that the braking assembly 10 can be used in a children's vehicle 1 or a wheelchair, etc. Some embodiments of the present application will be described by taking the braking assembly 10 used in the children's vehicle 1 as an example.

[0077] Referring to Figures 1 to 4 , the rotating wheel 20 of the children's vehicle 1 includes a locking hole 201, and the locking hole 201 can be provided on one side of the rotating wheel 20 facing its rotating shaft. The locking holes 201 can be provided in multiple numbers, and the locking holes 201 can be arranged at intervals around the rotating shaft of the rotating wheel 20. The following will refer to Figures 1 to 10 to introduce the braking assembly 10 of the embodiment of the present application. Specifically, the braking assembly 10 includes a mounting seat 100, a locking member 200, and a driving member 300.

[0078] Referring to Figure 3 and Figure 4 , the mounting seat 100 is used for assembling and connecting the locking member 200, the driving member 300, the rotating wheel 20, etc. The locking member 200 is used to restrict the rotation of the rotating wheel 20. The following will introduce the specific connection settings between the locking member 200 and the mounting seat 100. The locking member 200 is movably connected to the mounting seat 100. For the convenience of describing and understanding the specific locking process of the locking member 200, a first direction X is defined. The locking member 200 can move relative to the mounting seat 100 along the first direction X to Figure 5 taking the orientation in Figure 5 as a reference, the first direction X can point to the left - right direction. Referring to Figure 6 , the locking member 200 can move from right to left and extend into the locking hole 201 to brake the rotating wheel 20. Referring to

[0079] Referring to Figure 2 and Figure 3 , the following will introduce the specific connection settings between the driving member 300 and the mounting seat 100. The driving member 300 is movably connected to one side of the mounting seat 100 along the first direction X. Taking the orientation in Figure 3 as a reference, the driving member 300 can be movably connected to the right side of the mounting seat 100. The driving member 300 can move relative to the mounting seat 100 to a locking position and an unlocking position. In some embodiments, the driving member 300 can slide linearly relative to the mounting seat 100 to switch between the locking position and the unlocking position. In other embodiments, the driving member 300 can also rotate around an axis relative to the mounting seat 100 to switch between the locking position and the unlocking position. Some embodiments of the present application will be described by taking the driving member 300 rotating relative to the mounting seat 100 as an example.

[0080] Referring to Figures 5 to 7, the driving member 300 is used to drive the locking member 200 to move. The following introduces the specific connection settings between the driving member 300 and the locking member 200. The driving member 300 includes a first pushing portion 310 and a second pushing portion 320. The first pushing portion 310 and the second pushing portion 320 can adopt different structures. When the driving member 300 moves to the locking position, the first pushing portion 310 can abut against the locking member 200, so that the locking member 200 at least partially extends into the locking hole 201 to realize the braking of the runner 20. The extending length of the locking member 200 in the locking hole 201 can be determined according to the actual situation. When the driving member 300 moves to the unlocking position, the second pushing portion 320 can abut against the locking member 200, so that the locking member 200 is disengaged from the locking hole 201 to realize unlocking, that is, the runner 20 can rotate normally.

[0081] Referring to Figure 7 , a first protruding portion 330 is provided between the first pushing portion 310 and the second pushing portion 320. Specifically, in some embodiments, the first protruding portion 330 can be provided on the first pushing portion 310. In other embodiments, the first protruding portion 330 can also be provided on the second pushing portion 320. In other embodiments, the first protruding portion 330 can also be provided at the junction position between the first pushing portion 310 and the second pushing portion 320. The specific setting position of the first protruding portion 330 can be determined according to the actual situation. It can be understood that along the first direction X, the first protruding portion 330 protrudes and extends towards the locking member 200, and the specific extending length of the first protruding portion 330 can be determined according to the actual situation.

[0082] In the technical solution of the present application, the brake assembly 10 includes a mounting seat 100, a locking member 200, and a driving member 300. The locking member 200 is movably connected to the mounting seat 100, and the locking member 200 can move relative to the mounting seat 100 along the first direction X. The driving member 300 is movably connected to one side of the mounting seat 100 along the first direction X. The driving member 300 is configured to be able to move relative to the mounting seat 100 to a locking position and an unlocking position, and the driving member 300 can drive the locking member 200 to move relative to the mounting seat 100 along the first direction X during the process of moving relative to the mounting seat 100. The driving member 300 includes a first pushing portion 310 and a second pushing portion 320. When the driving member 300 moves to the locking position, the first pushing portion 310 abuts against the locking member 200, so that at least a part of the locking member 200 extends into the locking hole 201. When the driving member 300 moves to the unlocking position, the second pushing portion 320 abuts against the locking member 200, so that the locking member 200 disengages from the locking hole 201. In the prior art, affected by the movement of the runner or the vibration of the brake assembly, etc., the locking member may directly switch from the locking position abutting against the first pushing portion to the unlocking position abutting against the second pushing portion, resulting in accidental unlocking of the locking member, that is, the braking stability of the existing brake assembly is poor. In this solution, a first protruding portion 330 is provided between the first pushing portion 310 and the second pushing portion 320. Along the first direction X, the first protruding portion 330 protrudes and extends towards the locking member 200, that is, the first protruding portion 330 can prevent the locking member 200 from directly switching from abutting against the first pushing portion 310 to abutting against the second pushing portion 320, reducing the situation of accidental unlocking of the locking member 200 and effectively improving the braking stability of the brake assembly 10. Compared with the prior art solution in which the locking member moves smoothly from the first pushing portion to the second pushing portion, the locking member 200 in this solution needs to cross the first protruding portion 330 from the position abutting against the first pushing portion 310 to the position abutting against the second pushing portion 320. Since there is a height difference between the first protruding portion 330 and the first pushing portion 310 and the second pushing portion 320, that is, this solution can provide strong feedback during the process of switching the movement position of the driving member 300, ensuring the accuracy of the switching operation of the driving member 300 between the locking position and the unlocking position.

[0083] Refer to Figure 7, the specific arrangement of the first protrusion 330 in some embodiments is described below. The first push portion 310 includes a first abutting surface 311, and the first abutting surface 311 is used to abut the locking member 200. It can be understood that the first abutting surface 311 can be a plane, a curved surface or an inclined surface. Some embodiments of the present application are described by taking the first abutting surface 311 as a plane as an example. The first protrusion 330 can be protruded from the first abutting surface 311. Further, the first protrusion 330 can be protruded from the side of the first abutting surface 311 facing the second push portion 320. Compared with the scheme without a protrusion, the first protrusion 330 of this scheme can prevent the locking member 200 from moving directly from the first abutting surface 311 to the second push portion 320, effectively avoiding the accidental release of the locking member 200, and ensuring the braking stability of the brake assembly 10.

[0084] Reference Figure 7 , the specific configuration of the first protrusion 330 in other embodiments is described below. The first push portion 310 includes a first abutting surface 311, and the first abutting surface 311 is used to abut the locking member 200. It can be understood that the first abutting surface 311 can be a plane, a curved surface, or an inclined surface. The first abutting surface 311 is provided with a groove, and the groove includes a first groove side wall 3121. The first groove side wall 3121 can be located on a side of the first groove 312 adjacent to the first push portion 310, so as to Figure 7 As a reference, the first groove sidewall 3121 is located on the left side of the first groove 312. It should be noted that the first groove sidewall 3121 can define a portion of the first groove 312, and the first groove sidewall 3121 can also define a portion of the first protrusion 330, that is, the first groove 312 is connected to the first protrusion 330, so this solution can define the first protrusion 330 while opening the first groove 312. When the driving member 300 is in the locking position, the locking member 200 can extend into the first groove 312 to achieve braking. Therefore, in the process of releasing the locking member 200, the locking member 200 needs to first escape from the first groove 312 of the first pushing portion 310, and then cross the first protrusion 330 of the first pushing portion 310 before moving to the second pushing portion 320 to complete the release. Compared with the solution of only setting the first protrusion 330, this solution can effectively suppress the accidental release of the locking member 200 and further improve the stability of the braking of the locking member 200. Furthermore, the groove side wall of the first groove 312 away from the second pushing portion 320 can also limit the first protrusion 330 to prevent the locking member 200 from being separated from the first pushing portion 310 in a direction away from the second pushing portion 320, causing brake failure.

[0085] Reference Figure 7, the specific setting of the first protrusion 330 in other embodiments will be introduced below. The first pushing portion 310 includes a first abutting surface 311 for abutting against the locking member 200. It can be understood that the first abutting surface 311 can be a flat surface, a curved surface, an inclined surface, etc. The first protrusion 330 protrudes from the first abutting surface 311. The first pushing portion 310 further includes a first groove 312 arranged at an interval from the first protrusion 330, that is, the first protrusion 330 and the first groove 312 can be arranged independently of each other. The specific interval distance between the first protrusion 330 and the first groove 312 can be determined according to the actual situation. The first groove 312 can be located on the side of the first protrusion 330 facing away from the second pushing portion 320. When the driving member 300 is in the locked position, the locking member 200 can extend into the first groove 312 to achieve braking. Therefore, during the unlocking process of the locking member 200, the locking member 200 needs to first escape from the first groove 312 of the first pushing portion 310 and then cross the first protrusion 330 of the first pushing portion 310 before it can move to the second pushing portion 320 to complete the unlocking. Compared with the solution of only setting the first protrusion, this solution can effectively prevent the accidental unlocking of the locking member 200 and further improve the stability of the braking of the locking member 200. Moreover, the groove side wall of the first groove 312 facing away from the second pushing portion 320 can also limit the first protrusion 330 to prevent the locking member 200 from disengaging from the first pushing portion 310 in the direction away from the second pushing portion 320, resulting in braking failure.

[0086] The specific setting of the first groove 312 will be introduced below. In some embodiments, the first groove 312 has a first groove bottom wall 3122, and the first groove bottom wall 3122 is arranged opposite to the locking member 200 along the first direction X. Along the first direction X, the distance from the first groove bottom wall 3122 to the first abutting surface 311 is D, that is, the groove depth of the first groove 312 is D. Among them, D satisfies: 0.5 mm ≤ D ≤ 2 mm. Exemplarily, D can be 0.5 mm, 0.7 mm, 1 mm, 1.2 mm, 1.5 mm, 2 mm, etc. With the above setting of the first groove 312 in this solution, it can not only limit the direct escape of the first protrusion 330 from the first groove 312, but also prevent the locking member 200 from getting stuck during normal unlocking.

[0087] Refer to Figure 6, the specific connection arrangement of the locking member 200 and the mounting seat 100 is described below. In some embodiments, the mounting seat 100 includes a mounting hole 110, and the locking member 200 can be penetrated through the mounting hole 110 and elastically connected to the mounting seat 100. Specifically, a first elastic member 130 can be provided, one end of the first elastic member 130 can be sleeved in the mounting hole 110, and the other end is connected to the locking member 200. When in the locked position, the locking member 200 can at least partially penetrate the mounting hole 110 and at least partially penetrate the locking hole 201. When in the unlocking position, the locking member 200 can at least partially penetrate the mounting hole 110 and come out of the locking hole 201. In this solution, the mounting hole 110 of the mounting seat 100 can limit and guide the locking member 200, and ensure the stability of the position switching of the locking member 200. In other embodiments, the mounting seat 100 can also be provided with a mounting groove, and the locking member 200 can be penetrated through the mounting groove and elastically connected to the mounting seat 100. In other embodiments, the mounting base 100 may also be provided with a slide rail, and the locking member 200 may slide in the slide rail to extend into or out of the locking hole 201. The specific connection arrangement of the locking member 200 may be determined according to actual conditions.

[0088] Reference Figures 4 to 6 In some embodiments, the brake assembly 10 includes a lock housing 400, the locking member 200 can be partially sleeved in the lock housing 400, and the lock housing 400 is elastically connected to the locking member 200. Specifically, a second elastic member 121 can be provided, one end of the second elastic member 121 can be sleeved in the lock housing 400, and the other end is connected to the locking member 200. It should be noted that the end of the lock housing 400 away from the locking member 200 can abut the driving member 300. The prior art does not make the lock housing and the locking member elastically connected, that is, when the locking member needs to be in a locked state and the locking member is not aligned with the locking hole, the locking member will abut the non-locking hole area of the rotating wheel and cannot effectively brake. In this solution, the lock shell 400 is elastically connected to the locking member 200, and the driving member 300 can press the lock shell 400 along the first direction X, so that the lock shell 400 can press the first elastic member 130 and the locking member 200. Even if the locking member 200 is not aligned with the locking hole 201 and abuts against the non-locking area of the rotating wheel 20, because the first elastic member 130 is compressed, the locking member 200 still has a driving force toward the locking hole 201. Therefore, when the rotating wheel 20 continues to rotate so that the locking member 200 is aligned with the locking hole 201, the locking member 200 can be directly extended into the locking hole 201 to achieve the locking operation. This solution can ensure the braking stability of the brake assembly 10.

[0089] Reference Figure 2, The specific movement settings of the driving member 300 will be introduced below. In some embodiments, the driving member 300 can rotate relative to the mounting base 100 about the rotation axis 202 of the rotating wheel 20, so that the driving member 300 is switched from the unlocking position to the locking position. In this solution, the position switching operation of the driving member 300 is convenient and fast. It can be understood that the driving member 300 can rotate about the rotation axis 202 in the clockwise direction or in the counterclockwise direction. It should be noted that the first direction X is parallel to the rotation axis 202 of the rotating wheel 20, and the position switching operation of the driving member 300 in this solution is convenient and fast. In other embodiments, the driving member 300 can also slide relative to the mounting base 100, so that the driving member 300 is switched from the unlocking position to the locking position. Some embodiments of the present application will be described by taking the driving member 300 rotating relative to the mounting base 100 as an example.

[0090] Referring to Figures 7 to 10 , The specific rotation settings of the driving member 300 will be introduced below. In some embodiments, the first pushing portion 310 has a first end 313 facing away from the second pushing portion 320, and the second pushing portion 320 has a second end 321 facing away from the first pushing portion 310. The first end 313 and the second end 321 can be spaced apart to jointly define a limiting groove 340. The braking assembly 10 includes a limiting post 500, and the limiting post 500 can pass through the limiting groove 340 to limit the rotation angle of the driving member 300 rotating about the rotation axis 202 of the rotating wheel 20. Referring to Figure 9 , when the first end 313 abuts against the limiting post 500, that is, the driving member 300 is in the first extreme position and cannot continue to rotate in the counterclockwise direction. Referring to Figure 10 , when the second end 321 abuts against the limiting post 500, that is, the driving member 300 is in the second extreme position and cannot continue to rotate in the clockwise direction. In this solution, the limiting post 500 passes through the limiting groove 340, which can effectively inhibit the excessive rotation of the driving member 300 and ensure the braking stability of the braking assembly 10.

[0091] Referring to Figure 8, The following introduces the specific setting of the limit post 500. In some embodiments, the brake assembly 10 includes a cover body 120. The cover body 120 is detachably connected to the mounting seat 100, and the cover body 120 can be arranged on the side of the mounting seat 100 facing away from the runner 20. Specifically, the cover body 120 can cover the mounting seat 100, that is, the cover body 120 can effectively prevent foreign objects from entering the mounting seat 100. The cover body 120 can be provided with a limit post 500, and the mounting seat 100 can be provided with an assembly hole. Along the first direction X, the limit post 500 can pass through the assembly hole. Compared with the scheme where the limit post is arranged on the mounting seat 100, the limit post 500 in this scheme can not only be assembled and connected to the mounting seat 100, but also limit the rotation of the driving member 300, that is, this scheme can optimize the overall structural arrangement of the brake assembly 10. Further, the limit post 500 can be provided with a connection hole 510, and a screw can be passed through the connection hole 510 to connect with the mounting seat 100. In addition, the cover body 120 can also be provided with a connection portion 122, and the connection portion 122 is detachably connected to the mounting seat 100, which can improve the stability of the assembly connection between the cover body 120 and the mounting seat 100. The specific setting of the connection portion 122 can be determined according to the actual situation.

[0092] Referring to Figure 7 , The following introduces the specific structure of the second pushing portion 320. In some embodiments, the second pushing portion 320 includes a second abutting surface 322, and the second abutting surface 322 is used to abut against the locking member 200. It can be understood that the second abutting surface 322 can be a plane, a curved surface or an inclined surface, etc. Some embodiments of the present application will be described by taking the second abutting surface 322 as a curved surface as an example. The second abutting surface 322 is provided with a second groove 323. When in the unlocking position, the locking member 200 can extend into the second groove 323, that is, the situation where the locking member 200 directly disengages from the second pushing portion 320 and abuts against the first pushing portion 310 can be reduced, preventing the brake assembly 10 from being accidentally braked. It should be noted that the groove depth of the second groove 323 can be greater than the groove depth of the first groove 312, so that the second pushing portion 320 can drive the locking member 200 to be normally unlocked and locked.

[0093] Referring to Figure 7, the second groove 323 includes a second groove side wall 3231, and the second groove side wall 3231 can define a portion of the second groove 323. The second groove side wall 3231 can be a groove side wall of the second groove 323 on a side away from the first groove 312. The second groove 323 also includes a second groove bottom wall 3232 opposite to the locking member 200. The second groove side wall 3231 includes a third end 3233 away from the second groove bottom wall 3232 and a fourth end 3234 connected to the second groove bottom wall 3232. In order to facilitate the description and understanding of the specific shape of the second groove 323, it is assumed that the second groove 323 has a central axis 3235 perpendicular to the second groove bottom wall 3232. The extension direction of the central axis 3235 can be parallel to the first direction X. From the third end 3233 to the fourth end 3234, the distance between the second groove sidewall 3231 and the central axis 3235 gradually decreases, that is, the second groove sidewall 3231 is inclined relative to the central axis 3235. This solution can ensure the smoothness of the locking member 200 in the second groove 323 and avoid the situation of being stuck. In other embodiments, the other groove sidewall of the second groove 323 opposite to the second groove sidewall 3231 can also be inclined relative to the central axis 3235, and the specific setting can be determined according to the actual situation.

[0094] Reference Figure 7 In some embodiments, the second abutting surface 322 may be provided with a second protrusion 350. The second protrusion 350 may extend toward the locking member 200, and the second protrusion 350 is located on the side of the second groove 323 away from the second pushing portion 320. The second protrusion 350 of this solution can limit the movement of the locking member 200 from the second pushing portion 320 in the direction away from the first pushing portion 310, thereby preventing the brake assembly 10 from failing in braking. Furthermore, the second groove sidewall 3231 may define a portion of the second protrusion 350, and because the second groove sidewall 3231 may also define a portion of the second groove 323, that is, the second groove 323 is connected to the second protrusion 350, that is, this solution can effectively improve the braking stability of the brake assembly 10.

[0095] The second embodiment of the present application provides a baby stroller 1, which includes at least one brake assembly 10 and a rotating wheel 20. Some embodiments of the present application are described by taking two brake assemblies 10 as an example, and the two brake assemblies 10 can be arranged relatively along the first direction X. The brake assembly 10 of the baby stroller 1 includes a mounting seat 100, a locking member 200 and a driving member 300. The driving member 300 includes a first pushing portion 310 and a second pushing portion 320. When the driving member 300 moves to the locking position, the first pushing portion 310 abuts against the locking member 200 so that the locking member 200 at least partially extends into the locking hole 201. When the driving member 300 moves to the unlocking position, the second pushing portion 320 abuts against the locking member 200 so that the locking member 200 is released from the locking hole 201. In the prior art, due to the influence of the movement of the rotating wheel or the vibration of the brake assembly, the locking member will directly switch from the locking position abutting the first pushing portion to the unlocking position abutting the second pushing portion, resulting in accidental unlocking of the locking member, that is, the braking stability of the existing brake assembly is poor. In this solution, a first protrusion 330 is provided between the first pushing portion 310 and the second pushing portion 320, and the first protrusion 330 protrudes and extends toward the locking member 200 along the first direction X, that is, the first protrusion 330 can prevent the locking member 200 from directly switching from abutting with the first pushing portion 310 to abutting with the second pushing portion 320, thereby reducing the situation where the locking member 200 is accidentally released, and effectively improving the braking stability of the brake assembly 10. Compared with the solution of the prior art in which the locking member moves smoothly from the first pushing portion to the second pushing portion, the locking member 200 of this solution needs to switch from the position abutting against the first pushing portion 310 to the position abutting against the second pushing portion 320 across the first protrusion 330. Because there is a height difference between the first protrusion 330 and the first pushing portion 310 and the second pushing portion 320, that is, this solution can provide strong feedback for the driving member 300 in the process of switching the movement position, and ensure the accuracy of the switching operation of the driving member 300 between the locking position and the release position.

[0096] Reference Figure 1 The structure of the child stroller 1 of some embodiments is introduced below. The child stroller 1 includes a seat 50, and a plurality of rotating wheels 20 may be provided at the bottom of the seat 50. Some embodiments of the present application are described by taking the provision of four rotating wheels 20 as an example. The child stroller 1 may include a front bracket 60 and a rear bracket 70. The front bracket 60 may connect the front rotating wheel 20 to the front side of the seat 50, and the rear bracket 70 may connect the rear rotating wheel 20 to the rear side of the seat 50. The child stroller 1 may also include a handlebar 90 and a locking joint 80, etc. The locking joint 80 may connect the handlebar 90 to the seat 50. Referring to Figure 1 and Figure 2 The baby stroller 1 may include a pivot pipe 30 and a brake pedal 40 connected to each other. The two ends of the pivot pipe 30 may be connected to two rotating wheels 20 located at the rear side of the stroller body.

[0097] In some embodiments, the baby carriage 1 includes a pivot tube 30 and a brake pedal 40 that are connected to each other. The pivot tube 30 is connected to a driving member 300. After being driven, the brake pedal 40 can cause the pivot tube 30 to drive the driving member 300 to rotate, so that the driving member 300 is switched from a locked position to an unlocked position, thereby realizing the braking and unlocking of the runner 20. The locking and unlocking operations of this solution are convenient and fast.

[0098] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present application, then such directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If this specific posture changes, then the directional indications will also change accordingly.

[0099] In addition, if there are descriptions such as "first", "second", etc. involved in the embodiments of the present application, then such descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features.
