Abstract
Description
[Technical Field]
[0001] This utility model relates to the field of children's strollers, and more specifically to a brake pedal mechanism for children's strollers. [Background Technology]
[0002] Strollers are a common product used to carry children during their growth. Modern strollers are equipped with brakes to ensure they can stop securely on the ground when needed.
[0003] Currently, the braking and releasing mechanisms on strollers generally use rotating pedals. To brake, the adult presses the pedal backward, causing it to rotate and release. To release, the adult hooks the brake pedal upward with their toe, causing it to rotate in the opposite direction. However, this braking mechanism has the following drawbacks: First, hooking the brake pedal upward with the toe is cumbersome, requiring the toe to reach under the pedal, making it difficult to find the correct position. Second, hooking the brake pedal with the toe can easily scratch the surface of shoes, especially shiny surfaces like leather shoes.
[0004] Therefore, this utility model was created based on the above-mentioned shortcomings. [Utility Model Content]
[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a brake pedal mechanism for a children's stroller that is simple in structure, easy to operate, and will not damage shoes.
[0006] This utility model is achieved through the following technical solution:
[0007] A brake pedal mechanism for a child stroller includes a support rod fixedly connected to the stroller frame. A fixed seat is fixedly mounted on the support rod. A footrest that can be stepped on and slides longitudinally relative to the fixed seat is connected to the fixed seat. A brake drive rod is provided inside the support rod, which can be driven by the footrest to move laterally when the footrest moves downward. A positioning structure is provided between the footrest and the fixed seat to position the footrest. The positioning structure includes a first locking position on the fixed seat and a second locking position below the first locking position. The footrest has a locking member that can alternately stop between the first locking position and the second locking position when it is stepped on. A first return spring is provided between the footrest and the fixed seat, which can push the footrest to move upward and reset when the footrest is released. A second return spring is provided between the brake drive rod and the support rod, which can push the brake drive rod to reset laterally when the footrest resets upward.
[0008] The fixed base is provided with an annular groove, and the first and second locking positions are provided on the side wall of the annular groove. In the initial state, the locking member is engaged with the first locking position. When the foot pedal is stepped down and released, the locking member moves along the annular groove and moves to the second locking position under the action of the first return spring. When the foot pedal is stepped down and released again, the locking member continues to move along the annular groove and returns to the first locking position under the action of the first return spring.
[0009] The locking component includes a swing rod that is movably connected to the footrest and can swing relative to the footrest. The lower end of the swing rod is provided with a convex shaft that can be inserted into an annular groove and engaged with a first locking position or a second locking position.
[0010] The foot pedal is equipped with a connecting shaft, and the upper end of the swing rod is rotatably connected to the connecting shaft.
[0011] The upper end of the swing rod is provided with a strip-shaped hole along its length, and the strip-shaped hole is sleeved on the connecting shaft and movably connected to the connecting shaft.
[0012] The annular groove includes a first slide section, a second slide section, a third slide section, a fourth slide section, and a fifth slide section connected in sequence. The first locking position is located at the top of the first slide section. The first slide section and the second slide section are connected by a first guide part that prevents the convex shaft from entering the fifth slide section and guides the convex shaft into the second slide section when the convex shaft moves downward. The second slide section and the third slide section are connected by a blocking part that can block the convex shaft and a second guide part that can guide the convex shaft into the upper end of the third slide section when the first return spring pushes the foot pedal upward. The second locking position is located at the upper end of the third slide section. The third slide section and the fourth slide section are connected by a guide sidewall that can guide the convex shaft into the fourth slide section and a blocking part that prevents the convex shaft from returning to the third slide section under the action of the first return spring. The fourth slide section, the fifth slide section, and the first slide section are interconnected, so that the convex shaft entering the fourth slide section returns to the first locking position at the top of the first slide section under the action of the first return spring.
[0013] The fixed base includes a front seat and a rear seat, both of which are provided with annular grooves. The foot pedal is inserted between the front and rear seats and can move up and down. The convex shaft protrudes from the front and rear sides of the swing rod and is inserted into the corresponding annular groove.
[0014] Both the front and rear seats are provided with vertically extending guide grooves, and the footrest is provided with guide blocks that slide in cooperation with the guide grooves.
[0015] The footrest is provided with a first inclined surface, and the brake drive rod is provided with a second inclined surface that abuts against the first inclined surface and can be pushed by the first inclined surface when the footrest moves downward. When the first inclined surface pushes the second inclined surface downward, the brake drive rod moves laterally to drive the brake mechanism of the stroller to brake or release the brake.
[0016] Compared with the prior art, the present invention has the following advantages:
[0017] 1. The fixed base of this utility model is provided with a first locking position and a second locking position located below the first locking position. The engaging member on the footrest can alternately stop between the first and second locking positions when the footrest is stepped on. That is, when the engaging member is in the first locking position, the footrest is positioned. When the footrest is stepped on, the engaging member engages with the second locking position, the footrest descends a certain height and is positioned. During the descent, the footrest drives the brake lever to move laterally to complete the braking or releasing of the brake. When the footrest is stepped on again, the engaging member returns to the first locking position, and the footrest returns to its original position. Therefore, braking or releasing the brake of the stroller only requires stepping on the footrest. Adults can easily find the correct position by stepping on the footrest with the sole of their shoes, without damaging the shoes. Moreover, the intermittent stepping can achieve the up-and-down reciprocating movement of the footrest to achieve braking or releasing the brake, making the operation very convenient and quick.
[0018] 2. In the initial position, the convex shaft on the swing arm of this utility model is engaged in the first locking position. When the foot pedal is pressed down, the convex shaft disengages from the first locking position and moves along the annular groove. When it reaches a certain position, the convex shaft abuts against the side wall of the annular groove. The side wall of the annular groove guides the convex shaft to continue moving, and the upper end of the swing arm rotates relative to the fixed seat. After reaching the set position, the foot pedal is released, and the first return spring pushes the foot pedal upward to return to its original position. The convex shaft then continues to move forward in the annular groove until it reaches the second locking position and stops. At this time, the foot pedal is positioned. When the footrest is positioned below the first locking position, its position allows the brake drive lever to maintain its position after lateral movement. Even when the stroller is in a braking or de-braking state, when the footrest is pressed down again, the cam shaft disengages from the second locking position and continues to move along the annular groove. When it reaches the set position, the footrest is released, and the first return spring pushes the footrest upward to reset it. The cam shaft continues to move within the annular groove and returns to the first locking position. At this point, the footrest releases the brake drive lever, putting the stroller's braking mechanism in a de-braking or braking state. Therefore, intermittently pressing the footrest positions the footrest via the swing lever and its cam shaft, thereby positioning the brake drive lever to maintain the stroller's braking or de-braking state. The movement of the cam shaft within the annular groove achieves footrest positioning, a very ingenious design.
[0019] 3. This utility model has a simple structure, is easy to operate, and is suitable for widespread application. [Attached Image Description]

Detailed Implementation Methods
[0025] The present invention will be further described below with reference to the accompanying drawings:
[0026] like Figures 1 to 5 As shown, a stroller brake pedal mechanism includes a support rod 1 fixedly connected to the stroller frame 100. A fixed seat 2 is fixedly mounted on the support rod 1, and a footrest 3, which can be stepped on and slides longitudinally relative to the fixed seat 2, is connected to the fixed seat 2. A brake drive rod 4 is provided inside the support rod 1, which can be driven by the footrest 3 to move laterally when the footrest 3 moves downward. When the footrest 3 moves downward, it pushes the brake drive rod 4 to move laterally. During the lateral movement, the brake drive rod 4 drives the stroller's brake mechanism 200 to brake or unlock. The stroller's brake mechanism can be a conventional brake mechanism, which will not be described in detail here. In this embodiment, to convert the longitudinal sliding of the footrest 3 into the lateral movement of the brake drive rod 4, the footrest 3 is provided with a first inclined surface 33, and the brake drive rod 4 is provided with a second inclined surface 41 that abuts against the first inclined surface 41 and can be pushed by the first inclined surface 33 when the footrest 3 moves downward. When the first inclined surface 33 pushes the second inclined surface 41 downward, the brake drive rod 4 moves laterally, thereby driving the brake mechanism 200 of the stroller to brake or release the brake. In this embodiment, there are two brake drive rods 4 and they are arranged on both sides of the footrest 3. When the footrest 3 moves downward, it simultaneously drives both brake drive rods 4 to move laterally, so as to achieve synchronous braking or release of the two wheels. A second return spring 7 is provided between the brake drive rod 4 and the support rod 1, which can push the brake drive rod 4 to return laterally when the footrest 3 returns to its upward position.
[0027] like Figures 3 to 5As shown, a positioning structure is provided between the foot pedal 3 and the fixed base 2 to position the foot pedal 3. The positioning structure includes a first locking position 51 on the fixed base 2 and a second locking position 52 located below the first locking position 51. The foot pedal 3 is provided with a locking member 53 that can alternately stop between the first locking position 51 and the second locking position 52 when it is stepped on. A first return spring 6 is provided between the foot pedal 3 and the fixed base 2 to push the foot pedal 3 upward to reset when it is released. By alternately engaging the locking member 53 with the first locking position 51 and the second locking position 52, the foot pedal 3 can stop in different positions to achieve braking or releasing the brake via the brake drive lever 4. Specifically, when the pedal 3 is pressed down to the set position and then released, the pedal 3 moves downward and, under the action of the first return spring 6, the engaging member 53 moves from the first engaging position 51 to the second engaging position 52, causing the pedal 3 to move from a high position to a low position and remain in the low position. During this movement, the pedal 3 drives the brake lever 4 to move laterally, thereby braking or releasing the brake. When the pedal 3 is pressed down again, the pedal 3 continues to move downward, and when released, it returns to the high position under the action of the first return spring 6. At this time, the engaging member 53 returns to the first engaging position 51, thereby releasing or braking. Therefore, by intermittently pressing the pedal 3, the engaging member 53 alternates between the first engaging position 51 and the second engaging position 52, realizing the reciprocating movement of the pedal 3, and braking or releasing the brake during the reciprocating movement. The entire braking or releasing operation only requires pressing the sole of the shoe against the pedal 3, which is convenient and quick and will not damage the shoes.
[0028] like Figures 3 to 5 As shown, the fixed base 2 is provided with an annular groove 54, and the first locking position 51 and the second locking position 52 are provided on the side wall of the annular groove 54. In the initial state, the locking member 53 is engaged with the first locking position 51. When the foot pedal 3 is stepped down and released, the locking member 53 moves along the annular groove 54 and moves to the second locking position 52 under the action of the first return spring 6. When the foot pedal 3 is stepped down and released again, the locking member 53 continues to move along the annular groove 54 and returns to the first locking position 51 under the action of the first return spring 6.
[0029] like Figures 3 to 5As shown, the engaging component 53 includes a swing rod 531 movably connected to the footrest 3 and capable of swinging relative to the footrest 3. The lower end of the swing rod 531 is provided with a convex shaft 532 that inserts into an annular groove 54 and can engage with the first locking position 51 or the second locking position 52. In order for the footrest 3 to stop at different heights, the first locking position 51 and the second locking position 52 cannot be in the same vertical direction. They are offset backward in the left and right lateral directions. In this case, in order for the engaging component 53 to engage with the first locking position 51 or the second locking position 52, the engaging component 53 includes a swing rod 531 movably connected to the footrest 3. When the convex shaft 532 moves along the annular groove 54, the swing rod 531 swings relative to the footrest 3, thereby ensuring that the convex shaft 532 can alternately stop in the first locking position 51 and the second locking position 52, and ensuring that the footrest 3 can alternately descend and rise when stepping down.
[0030] like Figures 3 to 5 As shown, the foot pedal 3 is provided with a connecting shaft 31, and the upper end of the swing rod 531 is rotatably connected to the connecting shaft 31. In this embodiment, the upper end of the swing rod 531 is provided with a strip-shaped hole 533 along its length direction. The strip-shaped hole 533 is sleeved on the connecting shaft 31 and is movably connected to the connecting shaft 31, which can avoid jamming that may occur when stepping on the foot pedal 3.
[0031] like Figure 5As shown, the annular groove 54 includes a first sliding groove section 541, a second sliding groove section 542, a third sliding groove section 543, a fourth sliding groove section 544, and a fifth sliding groove section 545 connected in sequence. The first locking position 51 is located at the top of the first sliding groove section 541. The first sliding groove section 541 is provided with a first guide part 55 at the junction of the first sliding groove section 541 and the second sliding groove section 542, which can prevent the convex shaft 532 from entering the fifth sliding groove section 545 and guide the convex shaft 532 into the second sliding groove section 542 when it moves downward. The second sliding groove section 542 is provided with a blocking part 56 at the junction of the second sliding groove section 542 and the third sliding groove section 543, which can block the convex shaft 532. The first return spring 6 pushes the foot pedal upward. When seat 3 is used, it can guide the convex shaft 532 into the second guide part 57 at the upper end of the third slide section 543. The second locking position 52 is provided at the upper end of the third slide section 543. The third slide section 543 and the fourth slide section 544 are provided with a guide side wall 58 that can guide the convex shaft 532 into the fourth slide section 544 and a blocking part 59 that prevents the convex shaft 532 from returning to the third slide section 543 under the action of the first return spring 6. The fourth slide section 544, the fifth slide section 545 and the first slide section 541 are interconnected, so that the convex shaft 532 entering the fourth slide section 544 returns to the first locking position 51 at the top of the first slide section 541 under the action of the first return spring 6. When the footrest 3 is pressed, the swing arm 531 and the footrest 3 move downwards simultaneously. The cam shaft 532 moves downwards along the side wall of the first slide section 541 and is blocked by the first guide part 55 at the junction of the first slide section 541 and the second slide section 542. At this time, the pressure on the footrest 3 is maintained, and the first guide part 55 can guide the cam shaft 532 into the second slide section 542. When the cam shaft 532 moves along the second slide section 542 to the set position, it is blocked by the blocking part 56. At this time, the pressure on the footrest 3 is released, and the first return spring 6 pushes the footrest 3 to return upwards. The second guide part 57 touches the cam shaft 532 and guides the cam shaft 532 into the upper end of the third slide section 543. At this time, it reaches the second locking position 52, and the footrest 3 is held in the low position. At this time, the braking state or the released braking state of the stroller is also maintained. When it is necessary to release or apply the brake, pressing the foot pedal 3 again causes the cam shaft 532 to move downwards from the upper end of the third slide section 543. During its downward movement, it contacts the guide side wall 58 and is guided into the fourth slide section 544. At this point, releasing the pressure on the foot pedal 3 causes the first return spring 6 to push the foot pedal 3 back upwards. The cam shaft 532 contacts the blocking part 59 and cannot return to the third slide section 543. The cam shaft 532 then moves along the fourth slide section 544 and the fifth slide section 545, returning to the first locking position 51 at the upper end of the first slide section 541, thus releasing or applying the brake on the stroller. By pressing the foot pedal 3 twice, the cam shaft 532 completes one full rotation within the annular groove 54, achieving one switch between braking and releasing the brake on the stroller.
[0032] like Figure 4 As shown, the fixed base 2 includes a front seat body 21 and a rear seat body 22. Both the front seat body 21 and the rear seat body 22 are provided with annular grooves 54. The foot pedal 3 is inserted between the front seat body 21 and the rear seat body 22 and can move up and down. The convex shaft 532 protrudes from the front and rear sides of the swing rod 531 and is inserted into the corresponding annular grooves 54. Therefore, both ends of the convex shaft 532 are inserted into the corresponding annular grooves 54, making the foot pedal 3 move up and down smoothly and not easily jammed.
[0033] like Figure 4 As shown, both the front seat 21 and the rear seat 22 are provided with vertically extending guide grooves 23, and the foot pedal 3 is provided with guide blocks 32 that slide in cooperation with the guide grooves 23, which further makes the up-and-down movement of the foot pedal 3 very smooth.
[0034] The present invention has been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the invention.
