[0001] The present invention relates to the field of strollers, and more particularly to a stroller braking mechanism and a stroller equipped with the same. [Background technology]

[0002] Strollers are widely used tools designed to facilitate outdoor activities for infants and young children. Currently, conventional strollers have front and rear wheels at the bottom. The number of rear wheels is generally two, and each rear wheel is provided with a corresponding brake mechanism. When the stroller needs to be stopped, the user can fully brake the stroller only by stepping on the brake mechanisms of the two rear wheels. Conventional strollers have the following problems: 1. The user can fully brake the stroller only by stepping on the brake mechanisms of the two rear wheels, which is cumbersome and inconvenient. 2. The user is likely to only step on the brake mechanism of one rear wheel, which may cause the stroller to not be fully braked and may cause the stroller to slide down, posing a major safety hazard.

DETAILED DESCRIPTION OF THE INVENTION

[0045] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings, along with embodiments thereof, in order to explain the technical contents and structural features of the present invention in detail.

[0046] 1, 2 and 5, a stroller 200 according to the present invention includes a seat 201 and a stroller braking mechanism 100. As shown in FIG.

[0047] 5, 12 and 15, in a first embodiment of the stroller brake mechanism 100, the stroller brake mechanism 100 includes a body frame 1, a brake drive unit, an interlocking unit 4, a brake lock 5 and wheels 6, the brake drive unit is provided on the body frame 1, two interlocking units 4 are slidably provided on both the left and right sides of the body frame 1, both ends of the brake drive unit abut against the two interlocking units 4, each of which is fixedly connected to a brake lock 5, and two wheels 6 are pivotally mounted on both the left and right sides of the body frame 1, and the brake drive unit presses the interlocking units 4 to drive them to operate together with the brake locks 5, thereby engaging the brake locks 5 on both sides with the wheels 6, thereby stopping both wheels simultaneously. A seat 201 is provided on the body frame 1 and is for a baby to ride on. Here, the brake drive unit includes a brake pedal 2 and a drive member 3. The brake pedal 2 is mounted on the middle part of the body frame 1 so as to be slidable up and down. Specifically, the brake pedal 2 is mounted on the mounting member 13 of the body frame 1 so as to be slidable up and down. The interlocking unit 4 is mounted on the body frame 1 so as to be slidable up and down. Both ends of the brake pedal 2 abut against two drive members 3, and the drive member 3 is mounted on the body frame 1 so as to be slidable left and right. The drive member 3 abuts against the interlocking unit 4. Specifically, one end of the drive member 3 is mounted on the mounting member 13 so as to be slidable left and right. The drive member 3 is provided with a first position limiting groove 32 along the sliding direction. The body frame 1 is provided with a first position limiting shaft 112, which is slidably inserted into the first position limiting groove 32. That is, the first position limiting shaft 112 can slide relative to the first position limiting groove 32 of the drive member 3, and the first position limiting shaft 112 can perform a position limiting function, but is not limited thereto.By sliding the brake pedal 2, the two driving members 3 are pushed and slid, and the two driving members 3 operate the two interlocking units 4, respectively, and further move the brake locks 5 on both sides, causing the brake locks 5 on both sides to engage with the wheels 6, thereby stopping the wheels on both sides simultaneously.

[0048] 5 and 8 , in this embodiment, the brake pedal 2 is located above two driving members 3, and a first inclined surface 21 is provided on each side of the brake pedal 2. A second inclined surface 31 is provided on one end of the driving member 3, and the first inclined surface 21 is fitted into and connected to the second inclined surface 31. The fitting action between the first inclined surface 21 and the second inclined surface 31 causes the brake pedal 2 to slide downward, and the brake pedal 2 pushes the driving members 3 to slide to both the left and right sides, respectively. However, this is not limiting, and for example, a driving method using a conventional inclined groove can be adopted between the brake pedal 2 and the driving members 3. Specifically, the brake driving unit further includes a first elastic returning member 8 for returning the brake pedal 2, and the first elastic returning member 8 is provided between the brake pedal 2 and the vehicle body frame 1. When the brake pedal 2 is slid downward, the brake pedal 2 compresses the first elastic return member 8, and when the brake pedal 2 is not constrained, the brake pedal 2 can slide upward and return due to the action of the first elastic return member 8. Specifically, the brake pedal 2 is provided with a first groove 24, one end of the first elastic return member 8 is inserted into the first groove 24, the vehicle body frame 1 is provided with a second groove 111, the other end of the first elastic return member 8 is inserted into the second groove 111, and the first elastic return member 8 is positioned by the first groove 24 and the second groove 111, but this is not limiting.

[0049] 5 to 7 , in this embodiment, the brake drive unit further includes an elastically deformable positioning member 7, and the brake pedal 2 is provided with a first track groove 22 and a second track groove 23. The first track groove 22 is located below the second track groove 23, and one end of the first track groove 22 is connected to one end of the second track groove 23. One end of the positioning member 7 is fixed within the vehicle body frame 1, and by sliding the brake pedal 2, the other end of the positioning member 7 is alternately engaged with the lowest step of the first track groove 22 and the lowest step of the second track groove 23. Specifically, the first track groove 22 and the second track groove 23 are both recessed downward, and both ends of the first track groove 22 are connected to both ends of the second track groove 23, respectively, and the first track groove 22 and the second track groove 23 form a closed rail. Here, the first track groove 22 and the second track groove 23 are both V-shaped, but are not limited to this, and for example, the first track groove 22 and the second track groove 23 may be U-shaped. Furthermore, for example, the first track groove 22 and the second track groove 23 may be obliquely upward long grooves. As shown in FIG. 6 , initially, the other end of the positioning member 7 is engaged with the lowest stage of the first track groove 22 (i.e., the middle part of the first track groove 22). After the brake pedal 2 is depressed to slide downward, the other end of the positioning member 7 slides from the rail on one side of the first track groove 22 to one side of the second track groove 23, and then slides to the lowest stage of the second track groove 23 (i.e., the middle part of the second track groove 23) as shown in FIG. 7 due to its own elastic restoring force, thereby realizing positioning with respect to the brake pedal 2. After the two driving members 3 respectively operate the two interlocking units 4 together with the two brake locks 5, the brake locks 5 on both sides remain engaged with the wheels 6, thereby maintaining the locked state of the wheels 6 by the brake pedal 2.After the brake pedal 2 is depressed again to slide it downward, the other end of the positioning member 7 slides along the rail on the other side of the second track groove 23, and the elastic restoring force of the positioning member 7 itself and the first elastic returning member 8 push the brake pedal 2 to return it to its original position, and the positioning member 7 slides from the second track groove 23 to the bottom of the first track groove 22 as shown in Figure 6, thereby realizing repositioning of the brake pedal 2. The brake pedal 2 no longer slides the driving member 3, and the driving member 3, interlocking unit 4 and brake lock 5 return to their original position and disengage from the wheel 6, thereby maintaining the wheel 6 unlocked by the brake pedal 2.

[0050] 9 to 14, interlocking unit 4 includes a pushing portion 41 and a pulling portion 42. Pushing portion 41 is provided within body frame 1 so as to be able to slide up and down, and pulling portion 42 is provided within body frame 1 so as to be able to slide up and down. Pulling portion 42 is fixedly connected to brake lock 5. By sliding drive member 3 of the brake drive unit, pushing portion 41 is caused to slide. As a result, pushing portion 41 pushes pulling portion 42, causing it to slide together with brake lock 5. Specifically, drive member 3 of the brake drive unit is provided with third inclined surface 33, and pushing portion 41 is provided with fourth inclined surface 411. Third inclined surface 33 of drive member 3 is located above fourth inclined surface 411 of pushing portion 41, and third inclined surface 33 is connected to fourth inclined surface 411 by being fitted therewith. More specifically, pushing portion 41 is located above pulling portion 42 and can slide downward while pushing pulling portion 42 to slide. By sliding the driving member 3 to both the left and right sides, the third inclined surface 33 and the fourth inclined surface 411 engage with each other, causing the driving member 3 to push the pushing portion 41 and slide downward, and the pushing portion 41 slides downward and pushes the pulling portion 42, causing it to slide together with the brake locks 5, thereby causing the brake locks 5 on both sides to engage with the wheels 6 and further lock the wheels 6 on both sides. However, this is not limited to this, and for example, a driving method using a conventional inclined groove can be adopted between the driving member 3 and the pushing portion 41. Furthermore, for example, the third inclined surface 33 of the driving member 3 can be positioned below the fourth inclined surface 411 of the pushing portion 41, and as the driving member 3 slides the pushing portion 41, the pushing portion 41 pushes the pulling portion 42 upward and slides it upward, causing the pulling portion 42 to pull the brake lock 5 and engage it with the wheel 6.

[0051] 9 to 14, in this embodiment, the pushing unit 41 includes a pushing member 412 and a pin 413. The pushing member 412 is slidably mounted in the body frame 1, and one end of the pin 413 is fixedly connected to the pushing member 412 and the other end of the pin 413 abuts against the pulling unit 42, with the pin 413 being located above the pulling unit 42. Specifically, the pushing member 412 is provided with a second position limiting groove 412a along its sliding direction, and the body frame 1 is provided with a second position limiting shaft 113, which is slidably inserted into the second position limiting groove 412a. That is, the second position limiting shaft 113 can slide relative to the second position limiting groove 412a of the pushing member 412, and the second position limiting shaft 113 can perform a position limiting function, but is not limited thereto. Furthermore, the interlocking unit 4 further includes a second elastic return member 43 for returning the pushing portion 41, and the second elastic return member 43 is provided between the pushing portion 41 and the vehicle body frame 1. More specifically, the second elastic return member 43 is fitted onto the pin 413, but is not limited to this. Here, the second elastic return member 43 can be a conventional elastic member such as a compression spring.

[0052] 9 to 14 again, in this embodiment, the pull portion 42 includes a first fixed member 421 and a first pulling member 422, the first fixed member 421 is arranged so as to be slidable up and down within the body frame 1 and is located below the pushing portion 41, one end of the first pulling member 422 is fixedly connected to the first fixed member 421 and the other end of the first pulling member 422 is fixedly connected to the brake lock 5, the middle portion of the first pulling member 422 forms an inverted U-shaped structure 422a and is supported by the body frame 1, and by sliding the first fixed member 421 downward and pulling the first pulling member 422, the first pulling member 422 pulls the brake lock 5 upward and engages the brake lock 5 with the wheel 6. The pin 413 of the pushing unit 41 pushes the first fixed member 421 to slide downward, and the first fixed member 421 pulls one end of the first pulling member 422 to slide downward, and since the middle part of the first pulling member 422 forms an inverted U-shaped structure 422a and is supported by the body frame 1, the other end of the first pulling member 422 rises to pull the brake lock 5, causing the brake lock 5 to rise and engage with the wheel 6, thereby locking the wheel 6. Specifically, the pulling unit 42 further includes a steering member 423, which is fixed within the body frame 1 and located on one side of the first fixed member 421, and the inverted U-shaped structure 422a of the first pulling member 422 is drilled into and supported within the steering member 423. More specifically, the pull unit 42 further includes a second fixed member 424, which is slidably mounted up and down within the vehicle body frame 1. One end of the second fixed member 424 is fixedly connected to the first pulling member 422, and the other end of the second fixed member 424 is fixedly connected to the brake lock 5. However, this is not limiting. For example, the first pulling member 422 may be directly and fixedly connected to the brake lock 5. Here, the first pulling member 422 may be a conventional steel wire, but is not limited to this. The first pulling member 422 may also be a conventional rope, etc.Furthermore, the pull unit 42 further includes a third elastic return member 425 for returning the second fixing member 424, and the third elastic return member 425 is provided between the second fixing member 424 and the vehicle body frame 1. When the first pulling member 422 pulls the second fixing member 424 to slide it upward, the second fixing member 424 compresses the third elastic return member 425, and when the second fixing member 424 is released, the second fixing member 424 slides downward and returns due to the elastic restoring force of the third elastic return member 425, thereby sliding the brake lock 5 downward and returning it, and disengaging the brake lock 5 from the wheel 6.

[0053] 15, the wheel 6 is provided with a plurality of engagement grooves 621 along the rotation direction thereof, and the brake lock 5 can engage with or disengage from the engagement grooves 621. In this embodiment, the wheel 6 includes a wheel body 61 and a hub 62, the wheel body 61 is pivotally attached to the vehicle body frame 1, the hub 62 is fitted onto the wheel body 61, and the engagement grooves 621 are provided in the hub 62, but this is not limiting.

[0054] 5 to 15, the specific operating principle of the first embodiment of the stroller brake mechanism 100 according to the present invention is as follows.

[0055] When it is necessary to brake the wheel 6, the brake pedal 2 is depressed, and the positioning member 7 slides from the lowest stage of the first track groove 22 to the lowest stage of the second track groove 23, and positions the brake pedal 2. In this process, the brake pedal 2 presses the drive members 3 on both sides, causing the drive members 3 to slide to the left and right, respectively. The drive members 3 slide and press the push member 412 of the interlocking unit 4, causing it to slide downward together with the pin 413. As a result, the pin 413 The first fixing member 421 is pushed to slide downward, and one end of the first pulling member 422 is pulled to lower it, but by raising the other end of the first pulling member 422, the first pulling member 422 pulls the second fixing member 424 and slides it upward together with the brake lock 5, so that the brake lock 5 engages with the engagement groove 621 of the wheel 6 and further locks the wheels 6 on both sides, thereby realizing double braking of the rear wheels of the stroller 200 and improving the ease of braking operation of the stroller 200.

[0056] When it is necessary to release the lock on the wheels 6, the brake pedal 2 is pressed again, whereby the positioning member 7 slides from the lowest stage of the second track groove 23 to the lowest stage of the first track groove 22, the brake pedal 2 returns and slides upward due to the action of the first elastic return member 8, the entire interlocking unit 4 returns due to the action of the second elastic return member 43 and the third elastic return member 425, and the brake lock 5 is returned, thereby disengaging the brake lock 5 from the engagement state with the wheels 6, thereby releasing the lock on both wheels 6.

When the first traction member 422 pulls the second fixing member 424 to slide upward, the second fixing member 424 compresses the third elastic return member 425, and when the second fixing member 424 is released, the second fixing member 424 can slide downward and return due to the elastic restoring force of the third elastic return member 425, thereby sliding the brake lock 5 downward and returning it, and disengaging the brake lock 5 from the engagement state with the wheel 6.

[0063] 16 to 24, the specific operating principle of the second embodiment of the stroller brake mechanism 100 according to the present invention is as follows.

[0064] When it is necessary to brake the wheels 6, the brake pedal 2 is depressed, which rotates the brake pedal 2 together with the drive member 3, and the drive part 35 of the drive member 3 presses the first roller 414 of the pushing part 41 of the interlocking unit 4, causing the first roller 414 to slide downward together with the pin 413, and the pin 413 slides downward, pushing the first fixing member 421 of the pulling part 42 to slide downward, and pulling one end of the first pulling member 422 to lower it, while the other end of the first pulling member 422 rises, pulling the second fixing member 424 and sliding it upward together with the brake lock 5, causing the brake lock 5 to engage with the engagement groove 621 of the wheel 6, and further locking both wheels 6, thereby realizing double braking of the rear wheels of the stroller 200 and improving the ease of braking operation of the stroller 200.

[0065] When it is necessary to release the lock on the wheels 6, the brake pedal 2 is rotated in the opposite direction, and the brake pedal 2 rotates the drive member 3 to return, and the entire interlocking unit 4 returns due to the action of the second elastic return member 43 and the third elastic return member 425, and by returning the brake lock 5, the brake lock 5 is disengaged from the engagement state with the wheels 6, thereby releasing the lock on both sides of the wheels 6.

[0066] Referring to Figures 1 and 2, the vehicle frame 1 includes a vehicle frame main body 11 and a rotating part 12, and the two rotating parts 12 are pivotally mounted on both the left and right sides of the vehicle frame main body 11, respectively, and the wheels 6 are pivotally mounted on the rotating parts 12.

The orientation member 203b is engaged between the body frame main body 11 and the rotating unit 12, thereby locking the body frame main body 11 and the rotating unit 12. By operating the drift operation unit 202, the drift operation unit 202 pulls the second pulling member 203a, and the second pulling member 203a pulls and slides the orientation member 203b, thereby disengaging it from the engaged state with the rotating unit 12, thereby releasing the lock on the body frame main body 11 and the rotating unit 12. This allows the rotating unit 12 to rotate 360° together with the wheels 6 relative to the body frame main body 11. In this embodiment, the wheel 6 is a rear wheel, but is not limited to this. Here, the second traction member 203a is a steel wire, but is not limited to this, and the second traction member 203a can be a conventional rope, etc. Furthermore, the rotation orientation unit 203 further includes a fourth elastic return member 203c for returning the orientation member 203b, and the fourth elastic return member 203c is provided between the orientation member 203b and the vehicle frame main body 11. When the drift operation part 202 is operated to drive the second traction member 203a to pull the positioning member 7 and slide it upward, the positioning member 7 compresses the fourth elastic return member 203c.After the drift operation unit 202 is released, the positioning member 7 slides downward and returns due to the action of the fourth elastic return member 203c, whereby the positioning member 7 re-engages between the body frame main body 11 and the rotating unit 12, thereby locking the body frame main body 11 and the rotating unit 12. Note that since pressing the drift operation unit 202 to pull the second pulling member 203a is a conventional technique, a description of the structure of the drift operation unit 202 will be omitted.

[0068] When it is necessary to make the stroller 200 driftable, the drift operating unit 202 is pressed, causing the drift operating unit 202 to pull the second traction member 203a, which then pulls and slides the orientation member 203b, disengaging it from the rotating unit 12, thereby releasing the lock on the body frame main body 11 and the rotating unit 12, and the rotating unit 12 can rotate 360° together with the wheels 6 relative to the body frame main body 11. When the drift operating unit 202 is released, the drift operating unit 202 returns, and the orientation member 203b returns by the action of the fourth elastic return member 203c to re-engage between the body frame main body 11 and the rotating unit 12, thereby locking the body frame main body 11 and the rotating unit 12.

[0069] As described above, the stroller 200 according to the present invention is provided with the stroller brake mechanism 100, and the brake drive unit drives the interlocking units 4 on both sides to push and slide them, causing the interlocking units 4 on both sides to operate the brake locks 5 on both sides, which then engage with and lock the wheels 6 on both sides.
