Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of children's vehicles, and in particular to a children's stroller. Background Art
[0002] Strollers on the market are generally equipped with a rider-controlled steering mechanism, allowing the child's orientation to be adjusted as needed, for example, facing the parent for interaction or facing away from the parent to enjoy the scenery. To facilitate the stroller's movement, the rear wheels are typically oriented and the front wheels are de-oriented when the rider is on the rear side, while the front wheels are oriented and the rear wheels are de-oriented when the rider is on the front side. However, the structure that implements this function is generally complex, difficult to manufacture, and expensive. Summary of the Invention
[0003] The present invention provides a child stroller which can realize the function of adjusting the orientation of the wheel parts while the rider changes direction with a simple structure, thereby reducing the manufacturing cost of the child stroller.
[0004] The present invention provides a child stroller comprising a first travel assembly, a second travel assembly, a rider support rod, and an orientation adjustment mechanism. The first travel assembly comprises a first wheel assembly. The second travel assembly comprises a second wheel assembly. The rider support rod rotates relative to the first travel assembly or the second travel assembly. The orientation adjustment mechanism comprises a first drive block and a second drive block. When the rider support rod rotates to the same side as the first travel assembly, the first drive block drives the first wheel assembly to align, and the second drive block drives the second wheel assembly to de-align. When the rider support rod rotates to the same side as the second travel assembly, the second drive block drives the second wheel assembly to align, and the first drive block drives the first wheel assembly to de-align.
[0005] In the above-mentioned stroller, the rider support rod can be rotated relative to the first traveling assembly or the second traveling assembly to realize the reversing function. When the rider rotates to the same side as the first traveling assembly, the orientation of the first wheel assembly and the deorientation of the second wheel assembly can be realized by the orientation adjustment mechanism. When the rider rotates to the same side as the second traveling assembly, the orientation of the second wheel assembly and the deorientation of the first wheel assembly can be realized by the orientation adjustment mechanism. That is, when the rider changes direction, the orientation adjustment function provided between the first traveling assembly, the second traveling assembly and the rider support rod can be used to facilitate the pushing of the stroller after the reversal. The orientation adjustment function of the orientation adjustment mechanism is mainly realized by the first drive block and the second drive block, and the structure is simple and easy to realize. The above-mentioned stroller can realize the function of adjusting the orientation of the wheel assembly while the rider changes direction with a simple structure, thereby reducing the manufacturing cost of the stroller.

DETAILED DESCRIPTION
[0032] like Figures 1 to 3 and Figure 18 As shown, one embodiment of the present invention provides a child stroller, comprising a first travel assembly 100, a second travel assembly 200, a rider support rod 300, an orientation adjustment mechanism 400, and a drift drive mechanism 500. This child stroller, with a simple structure, can simultaneously adjust the orientation of the wheels while the rider changes direction, thereby reducing the manufacturing cost of the child stroller.
[0033] Specifically, if Figure 1 、 Figure 12 and Figure 13 As shown, the first traveling assembly 100 includes a first wheel support rod 110 , a first wheel component 120 , a first orientation mechanism 130 and a first rotating shaft 140 .
[0034] like Figure 1 、 Figure 12 and Figure 13As shown, the first wheel support rod 110 is pivotally connected to the first wheel assembly 120. Specifically, one end of the first rotating shaft 140 is fixed to the first wheel support rod 110, and the first wheel assembly 120 is pivotally connected to the other end of the first rotating shaft 140. Of course, in other embodiments, one end of the first rotating shaft 140 can also be fixed to the first wheel assembly 120, and the first wheel support rod 110 is pivotally connected to the other end of the first rotating shaft 140. This is not limited to this. The first wheel assembly 120 includes a first wheel frame 121 and a first wheel body 122. The first wheel frame 121 is pivotally connected to the first wheel support rod 110, and the first wheel body 122 is rotatably mounted in the first wheel frame 121.
[0035] like Figure 1 、 Figure 12 and Figure 13 As shown, the first orientation mechanism 130 includes a first orientation pin 131 movably disposed on the first wheel support rod 110 and a first orientation slot 132 disposed on the first wheel frame 121. The first orientation pin 131 is inserted into the first orientation slot 132 to lock the first orientation mechanism 130, thereby maintaining the first wheel assembly 120 in a certain orientation relative to the first wheel support rod 110. The first orientation pin 131 is disengaged from the first orientation slot 132 to release the first orientation mechanism 130, thereby allowing the first wheel assembly 120 to rotate 360 degrees relative to the first wheel support rod 110. Of course, the first orientation mechanism 130 may also be of other forms, as long as it can be locked to achieve orientation of the first wheel assembly 120 and can be released to achieve de-orientation of the first wheel assembly 120.
[0036] Specifically, if Figure 1 、 Figure 10 and Figure 11 As shown, the second traveling assembly 200 includes a second wheel support rod 210 , a second wheel member 220 , a second orientation mechanism 230 and a second rotating shaft 240 .
[0037] like Figure 1 、 Figure 10 and Figure 11 As shown, the second wheel support rod 210 is pivotally connected to the second wheel assembly 220. Specifically, one end of the second rotating shaft 240 is fixed to the second wheel support rod 210, and the second wheel assembly 220 is pivotally connected to the other end of the second rotating shaft 240. Of course, in other embodiments, one end of the second rotating shaft 240 can also be fixed to the second wheel assembly 220, and the second wheel support rod 210 is pivotally connected to the other end of the second rotating shaft 240. The second wheel assembly 220 includes a second wheel frame 221 and a second wheel body 222. The second wheel frame 221 is pivotally connected to the second wheel support rod 210, and the second wheel body 222 is rotatably mounted in the second wheel frame 221.
[0038] like Figure 1 、 Figure 10 and Figure 11 As shown, the second orientation mechanism 230 includes a second orientation pin 231 movably disposed on the second wheel support rod 210 and a second orientation slot 232 disposed on the second wheel frame 221. The second orientation pin 231 is inserted into the second orientation slot 232 to lock the second orientation mechanism 230, thereby maintaining the second wheel assembly 220 in a certain orientation relative to the second wheel support rod 210. The second orientation pin 231 is disengaged from the second orientation slot 232 to release the second orientation mechanism 230, thereby allowing the second wheel assembly 220 to rotate 360 degrees relative to the second wheel support rod 210. Of course, the second orientation mechanism 230 may also be of other forms, as long as it can be locked to achieve orientation of the second wheel assembly 220 and can be released to achieve de-orientation of the second wheel assembly 220.
[0039] In this embodiment, Figure 1 As shown, one end of the first wheel support rod 110 away from the first wheel component 120 is pivotally connected to one end of the second wheel support rod 210 away from the second wheel component 220 .
[0040] Specifically, if Figures 1 to 5 As shown, the rider support bar 300 includes a rider body 310 and a rider mounting seat 320 connected to each other. The rider body 310 is generally rod-shaped, and the rider mounting seat 320 is generally disc-shaped. The rider support bar 300 can rotate relative to the first travel assembly 100 or the second travel assembly 200 to change the forward direction of the child stroller. For example, when the rider support bar 300 rotates to the same side as the first travel assembly 100, the child stroller moves along Figure 6 When the rider support rod 300 rotates to the same side as the second travel assembly 200, the child stroller moves along Figure 8 Move forward in the sixth direction D6.
[0041] Specifically, if Figures 1 to 3 As shown, the orientation adjustment mechanism 400 is disposed between the first traveling assembly 100, the second traveling assembly 200 and the rider support rod 300. Figure 6 and Figure 7 As shown, the driver support rod 300 rotates to the same side as the first traveling assembly 100, and the orientation adjustment mechanism 400 drives the first wheel component 120 to be oriented and the second wheel component 220 to be unoriented. Figure 8 and Figure 9 As shown, the driver support bar 300 rotates to the same side as the second traveling assembly 200 , and the orientation adjustment mechanism 400 drives the second wheel component 220 to be oriented and the first wheel component 120 to be released from orientation.
[0042] In this embodiment, if Figures 6 to 13As shown, the orientation adjustment mechanism 400 may include a fixed shell 410, a first driving block 421, a second driving block 422, a first driving rib 431, a second driving rib 432, a first traction member 441, a second traction member 442, a first reset member 451, a second reset member 452, a third reset member 453 and a fourth reset member 454.
[0043] Specifically, if Figures 1 to 3 As shown, the fixed housing 410 includes a first fixing seat 411, a second fixing seat 412, and a connecting seat 413. The first fixing seat 411 is pivotally connected to the first traveling assembly 100, and the second fixing seat 412 is fixed to the second traveling assembly 200. The first fixing seat 411 and the second fixing seat 412 enclose a storage space. The first fixing seat 411 is generally elliptical. The second fixing seat 412 includes a fixing seat body 412a and a connecting member 412b that are interconnected. The fixing seat body 412a is an elliptical disc-shaped structure that matches the first fixing seat 411. The connecting member 412b is generally sleeve-shaped and can be mounted on the end of the second wheel support rod 210 away from the second wheel assembly 220. The connecting seat 413 is fixed to the end of the first wheel support rod 110 away from the first wheel assembly 120. The connecting seat 413 is provided with a pivot shaft 413a that passes through the first fixing seat 411 and the fixing seat body 412a in sequence to achieve a coaxial pivot connection between the three. Please also see Figure 7 The connecting base 413, the first fixing base 411, and the fixing base body 412a are pivotally connected at a first pivot point M. The rider support rod 300 is pivotally connected to the side of the second fixing base 412 facing away from the first fixing base 411. The rider support rod 300 and the second fixing base 412 are pivotally connected at a second pivot point N. The second fixing base 412 is provided with a first guide post 411a and a second guide post 411b. Of course, in other embodiments, the first guide post 411a and the second guide post 411b may also be provided on the first fixing base 411. In this embodiment, the first pivot point M is located in the first direction D1 of the second pivot point N, and the first guide post 411a and the second guide post 411b are located between the first pivot point M and the second pivot point N.
[0044] In this embodiment, the connection base 413 is made of plastic material. Of course, in other embodiments, the connection base 413 can also be made of other materials.
[0045] Furthermore, if Figures 6 to 9As shown, the first drive block 421 and the second drive block 422 are movably disposed within the fixed housing 410, i.e., within the accommodation space. Specifically, the first drive block 421 is provided with a first elongated guide slot 421a, into which a first guide post 411a is inserted. The first guide slot 421a and the first guide post 411a cooperate to enable the first drive block 421 to reciprocate along the extension direction of the first guide slot 421a, i.e., the first direction D1 and the fifth direction D5. The second drive block 422 is provided with a second elongated guide slot 422a, into which a second guide post 411b is inserted. The second guide slot 422a and the second guide post 411b cooperate to enable the second drive block 422 to reciprocate along the extension direction of the second guide slot 422a, i.e., the first direction D1 and the fifth direction D5. Of course, the first drive block 421 and the second drive block 422 can also be movably disposed within the fixed housing 410 in other ways. The first direction D1 and the fifth direction D5 are opposite to each other.
[0046] Specifically, if Figure 3 As shown, the second fixing seat 412 is provided with a through-hole 412c connected to the accommodating space. The first driving block 421 can move along the fifth direction D5 until it passes through the through-hole 412c, and the second driving block 422 can move along the fifth direction D5 until it passes through the through-hole 412c. In this embodiment, there are two through-holes 412c, each of which can accommodate the first driving block 421 and the second driving block 422. The orientation adjustment mechanism 400 also includes a separator 411c, which is located between the first driving block 421 and the second driving block 422 and is used to separate the first driving block 421 and the second driving block 422. In other embodiments, there can be only one through-hole 412c, as long as it can accommodate the first driving block 421 and the second driving block 422.
[0047] Furthermore, if Figures 2 to 5 As shown, the first driving rib 431 and the second driving rib 432 are provided on the rider support rod 300, and the second fixing seat 412 is provided with a track 412d, along which the first driving rib 431 and the second driving rib 432 can move. Through the track 412d, the first driving rib 431 can abut against the first driving block 421, and the second driving rib 432 can abut against the second driving block 422. Please refer to Figures 6 to 9The first driving block 421 is located between the first driving rib 431 and the first directional mechanism 130. The rider support bar 300 rotates to the same side as the first travel assembly 100. The first driving rib 431 pushes the first driving block 421 counterclockwise to move in the first direction D1, locking the first directional mechanism 130. The second driving block 422 is located between the second driving rib 432 and the second directional mechanism 230. The rider support bar 300 rotates to the same side as the second travel assembly 200. The second driving rib 432 pushes the second driving block 422 clockwise to move in the first direction D1, locking the second directional mechanism 230.
[0048] In this embodiment, the first driving rib 431 and the second driving rib 432 are both arc-shaped ribs. The arc lengths of the first driving rib 431 and the second driving rib 432 are different. For example, the first driving rib 431 is shorter than the second driving rib 432. This prevents the first driving rib 431 from interfering with the movement of the second driving block 422 due to its excessive length when pushing against the first driving block 421.
[0049] Furthermore, if Figures 6 to 13 As shown, the two ends of the first pulling member 441 are respectively connected to the first driving block 421 and the first orientation mechanism 130. Specifically, the two ends of the first pulling member 441 are respectively connected to the end of the first driving block 421 near the first pivot point M and the end of the first orientation pin 131 near the first pivot point M. That is, the first pulling member 441 extends from the first driving block 421 to the first orientation pin 131. In this way, when the first driving block 421 moves in the fifth direction D5, the first pulling member 441 can drive the first orientation pin 131 to move in the fourth direction D4, causing the first orientation pin 131 to disengage from the first orientation slot 132, thereby releasing the first orientation mechanism 130.
[0050] Similarly, the two ends of the second pulling member 442 are respectively connected to the second driving block 422 and the second orientation mechanism 230. Specifically, the two ends of the second pulling member 442 are respectively connected to the end of the second driving block 422 near the first pivot point M and the end of the second orientation pin 231 near the first pivot point M. In other words, the second pulling member 442 extends from the second driving block 422 to the second orientation mechanism 230. In this way, when the second driving block 422 moves in the fifth direction D5, the second orientation pin 231 can be driven by the second pulling member 442 to move in the fourth direction D4, causing the second orientation pin 231 to disengage from the second orientation slot 232, thereby releasing the second orientation mechanism 230.
[0051] In this embodiment, the first pulling member 441 and the second pulling member 442 are both steel wires. Of course, in other embodiments, the first pulling member 441 and the second pulling member 442 may also be made of other materials.
[0052] Furthermore, if Figures 6 to 9As shown, the two ends of the first return member 451 respectively abut against the fixed housing 410 and the first driving block 421. Specifically, the first return member 451 is generally arranged along the first direction D1. One end of the first return member 451 is positioned against the end of the first driving block 421 near the first pivot point M, and the other end of the first return member 451 abuts against the fixed housing 410. The first return member 451 constantly moves the first driving block 421 in the direction that drives the first orientation mechanism 130 to release. In other words, the first return member 451 constantly moves the first driving block 421 in the fifth direction D5. Thus, when the rider support bar 300 rotates from the same side as the first travel assembly 100 to the same side as the second travel assembly 200, and the first driving rib 431 switches from abutting the first driving block 421 to a non-pushing state, the first driving block 421 can move in the fifth direction D5 under the elastic force of the first restoring member 451, thereby driving the first directional pin 131 in the fourth direction D4 via the first traction member 441 to disengage from the first directional slot 132, thereby releasing the first directional mechanism 130. The first restoring member 451 may be a spring, an elastic rubber column, or the like.
[0053] Similarly, if Figures 6 to 9 As shown, the two ends of the second return member 452 respectively abut against the fixed housing 410 and the second drive block 422. Specifically, the second return member 452 is generally arranged along the first direction D1, with one end of the second return member 452 positioned against the end of the second drive block 422 near the first pivot point M, and the other end of the second return member 452 abutting against the fixed housing 410. The second return member 452 constantly causes the second drive block 422 to move in the direction that drives the second orientation mechanism 230 to release, that is, the second return member 452 constantly causes the second drive block 422 to move in the fifth direction D5. Thus, when the rider support bar 300 rotates from the same side as the second travel assembly 200 to the same side as the first travel assembly 100, and the second driving rib 432 switches from abutting the second driving block 422 to a non-pushing state, the second driving block 422 can move in the fifth direction D5 under the elastic force of the second restoring member 452, thereby driving the second directional pin 231 in the fourth direction D4 via the second pulling member 442 to disengage from the second directional slot 232, thereby releasing the second directional mechanism 230. The second restoring member 452 may be a spring, an elastic rubber column, or the like.
[0054] Furthermore, if Figure 12 and Figure 13As shown, the two ends of the third reset member 453 respectively abut against the first wheel support rod 110 and the first directional pin 131. The third reset member 453 constantly locks the first directional mechanism 130, that is, the third reset member 453 constantly moves the first directional pin 131 toward the first directional slot 132. The elastic coefficient of the third reset member 453 is smaller than the elastic coefficient of the first reset member 451. Thus, when the first driving rib 431 is not abutting the first driving block 421, the elastic force of the first reset member 451 can overcome the elastic force of the third reset member 453 and move in the fifth direction D5, thereby releasing the first directional mechanism 130. When the first driving rib 431 abuts the first driving block 421, causing it to move in the fifth direction D5 and the first reset member 451 is compressed, the first directional pin 131, under the elastic force of the third reset member 453, moves into the first directional slot 132, thereby locking the first directional mechanism 130. The third restoring member 453 can be a spring, an elastic rubber column, etc.
[0055] Similarly, if Figure 10 and Figure 11 As shown, the two ends of the fourth reset member 454 respectively abut against the second wheel support rod 210 and the second directional pin 231. The fourth reset member 454 constantly locks the second directional mechanism 230, that is, the fourth reset member 454 constantly moves the second directional pin 231 toward the second directional slot 232. The elastic coefficient of the fourth reset member 454 is smaller than the elastic coefficient of the second reset member 452. Thus, when the second driving rib 432 is not abutting the second driving block 422, the elastic force of the second reset member 452 can overcome the elastic force of the fourth reset member 454 and move in the fifth direction D5, thereby releasing the second directional mechanism 230. When the second driving rib 432 abuts the second driving block 422, causing it to move in the first direction D1 and the second reset member 452 to be compressed, the second directional pin 231, under the elastic force of the fourth reset member 454, moves into the second directional slot 232, thereby locking the second directional mechanism 230. The fourth restoring member 454 can be a spring, an elastic rubber column, etc.
[0056] The specific working principle of the orientation adjustment mechanism 400 of this embodiment is as follows:
[0057] When the driver support rod 300 rotates to the same side as the first traveling assembly 100, as shown in FIG. Figure 6 and Figure 7As shown, the first driving rib 431 pushes against the first driving block 421, causing it to be positioned closer to the first pivot point M (i.e., more downward). At this point, the first pulling member 441 is released, and the first directional pin 131, under the elastic force of the third return member 453, moves in the third direction D3, inserting the first directional pin 131 into the first directional slot 132, thereby locking the first directional mechanism 130. Simultaneously, the second driving block 422, which is not pushed against, is positioned farther from the first pivot point M (i.e., more upward) under the elastic force of the second return member 452. At this point, the second pulling member 442 is tightened, and the second directional pin 231, pulled by the second pulling member 442, overcomes the elastic force of the fourth return member 454 and moves in the fourth direction D4, disengaging the second directional pin 231 from the second directional slot 232 and releasing the second directional mechanism 230. The third direction D3 is opposite to the fourth direction D4.
[0058] Similarly, when the driver support rod 300 rotates to the same side as the second traveling assembly 200, as shown in FIG. Figure 8 and Figure 9 As shown, the second driving rib 432 pushes against the second driving block 422, causing the second driving block 422 to be located closer to the first pivot point M (i.e., a lower position). At this time, the second pulling member 442 is released, and the second directional pin 231 moves in the third direction D3 under the elastic force of the fourth reset member 454, so that the second directional pin 231 is inserted into the second directional groove 232, thereby locking the second directional mechanism 230. At the same time, the first driving block 421, which is not pushed, is located farther away from the first pivot point M (i.e., a higher position) under the elastic force of the first reset member 451. At this time, the first pulling member 441 is tightened, and the first directional pin 131, pulled by the first pulling member 441, overcomes the elastic force of the third reset member 453 and moves in the fourth direction D4, causing the first directional pin 131 to disengage from the first directional groove 132, thereby releasing the first directional mechanism 130.
[0059] In another embodiment, if Figures 14 to 17 As shown, the orientation adjustment mechanism 400 includes a fixed shell 410, a first driving block 421, a second driving block 422, a first driving rib 431, a second driving rib 432, a first pulling member 441, a second pulling member 442, a first restoring member 451, a second restoring member 452, a third restoring member 453 and a fourth restoring member 454. The structure of the orientation adjustment mechanism 400 in this embodiment is similar to that of the aforementioned Figures 1 to 13 The orientation adjustment mechanism 400 in the corresponding embodiment is basically the same, with the following differences:
[0060] First, if Figures 14 to 17As shown, one end of the first pulling member 441 is connected to the first orientation mechanism 130 (specifically, the first orientation pin 131), and the other end passes through the partition 411c and is connected to the first driving block 421. Thus, the first orientation pin 131, the first pulling member 441, the first driving block 421, and the partition 411c form a pulley-like structure, so that the movement direction of the first orientation pin 131 is opposite to that of the first driving block 421. As a result, when the first driving block 421 moves along the first direction D1, it can drive the first orientation pin 131 to move along the fourth direction D4, thereby releasing the first orientation mechanism 130.
[0061] Similarly, if Figures 14 to 17 As shown, one end of the second pulling member 442 is connected to the second orientation mechanism 230, specifically to the second orientation pin 231, and the other end passes around the partition 411c and is connected to the second driving block 422. Thus, the second orientation pin 231, the second pulling member 442, the second driving block 422, and the partition 411c form a pulley-like structure, so that the movement direction of the second orientation pin 231 is different from the movement direction of the second driving block 422. Thus, movement of the second driving block 422 along the first direction D1 can drive the second orientation pin 231 to move along the fourth direction D4, thereby unlocking the second orientation mechanism 230.
[0062] Secondly, if Figure 14 and Figure 15 As shown, the rider support rod 300 rotates to the same side as the first travel assembly 100, and the second driving rib 432 pushes the second driving block 422 along the first direction D1 to put the second orientation mechanism 230 in the unlocked state. At the same time, the first driving block 421 is not pushed by the first driving rib 431, so that the first orientation mechanism 130 is in the locked state. Figure 16 and Figure 17 As shown, the rider support rod 300 rotates to the same side as the second travel assembly 200, and the first driving rib 431 pushes the first driving block 421 along the first direction D1 to put the first directional mechanism 130 in an unlocked state. At the same time, the second driving block 422 is not pushed by the second driving rib 432, so that the second directional mechanism 230 is in a locked state.
[0063] In addition, if Figures 14 to 17As shown, in this embodiment, because the first directional pin 131 and the first driving block 421 move in opposite directions, when the first driving rib 431 no longer pushes against the first driving block 421, the first driving block 421 can move in the fifth direction D5 under the elastic force of the first return member 451. Here, the first pulling member 441 is relaxed, and the first directional pin 131 simultaneously moves in the third direction D3 under the elastic force of the third return member 453, thereby locking the first directional mechanism 130. Therefore, in this embodiment, the elastic coefficient of the third return member 453 does not need to be less than the elastic coefficient of the first return member 451.
[0064] Similarly, if Figures 14 to 17 As shown, in this embodiment, because the second orientation pin 231 and the second driving block 422 move in opposite directions, when the second driving rib 432 no longer pushes against the second driving block 422, the second driving block 422 can move in the fifth direction D5 under the elastic force of the second return member 452. Here, the second pulling member 442 is relaxed, and the second orientation pin 231 simultaneously moves in the third direction D3 under the elastic force of the fourth return member 454, thereby locking the first orientation mechanism 130. Therefore, in this embodiment, the elastic coefficient of the fourth return member 454 does not need to be less than the elastic coefficient of the second return member 452.
[0065] The specific working principle of the orientation adjustment mechanism 400 of this embodiment is as follows:
[0066] When the driver support rod 300 rotates to the same side as the first traveling assembly 100, as shown in FIG. Figure 14 and Figure 15 As shown, the second driving rib 432 pushes against the second driving block 422, and the second driving block 422 overcomes the elastic force of the second return member 452 and is positioned closer to the first pivot point M (i.e., a lower position). At this time, the second pulling member 442 is tightened, and the second pulling member 442 pulls the second directional pin 231 to overcome the elastic force of the fourth return member 454 and move in the fourth direction D4, causing the second directional pin 231 to disengage from the second directional slot 232, thereby releasing the second directional mechanism 230. At the same time, the first driving block 421, which is not pushed, is positioned farther away from the first pivot point M (i.e., a higher position) under the elastic force of the first return member 451. At this time, the first pulling member 441 is released, and the first directional pin 131 moves in the third direction D3 under the elastic force of the third return member 453, causing the first directional pin 131 to be inserted into the first directional slot 132, thereby locking the first directional mechanism 130.
[0067] Similarly, if Figure 16 and Figure 17As shown, when the rider support bar 300 rotates to the same side as the second travel assembly 200, the first driving rib 431 pushes against the first driving block 421. The first driving block 421 overcomes the elastic force of the first return member 451 and is positioned closer to the first pivot point M (i.e., a lower position). At this time, the first pulling member 441 is tightened. Simultaneously, the first pulling member 441 pulls the first directional pin 131, overcoming the elastic force of the third return member 453 and moving it in the fourth direction D4. This causes the first directional pin 131 to disengage from the first directional slot 132, thereby releasing the first directional mechanism 130. Simultaneously, the second driving block 422, which is not pushed, is positioned farther from the first pivot point M (i.e., a higher position) under the elastic force of the second return member 452. At this time, the second pulling member 442 is released, and the second directional pin 231 moves in the third direction D3 under the elastic force of the fourth return member 454, inserting the second directional pin 231 into the second directional slot 232, thereby locking the second directional mechanism 230.
[0068] In yet another embodiment, Figure 14-17 For the corresponding embodiments, please refer to Figures 18 to 24 The orientation adjustment mechanism 400 further includes a driver 460 and a fifth reset member 455. The driver 460 is generally annular and is provided with a first drive rib 431 and a second drive rib 432. The driver 460 is pivotally connected to the rider support rod 300. The first drive rib 431 and the second drive rib 432 are both movable on the track 412d. The first drive rib 431 can abut against the first drive block 421, and the second drive rib 432 can abut against the second drive block 422. When the rider support rod 300 changes direction, the driver 460 remains stationary relative to the rider support rod 300. The ends of the fifth reset member 455 respectively abut against the driver 460 and the rider support rod 300, thereby permanently securing the driver 460 and the rider support rod 300. The fifth reset member 455 may be a spring, an elastic rubber column, or the like.
[0069] Specifically, if Figures 18 to 22As shown, the drift drive mechanism 500 includes a third traction member 510 and a drift operating member 520. The two ends of the third traction member 510 are connected to the drift operating member 520 and the driving member 460, respectively. In this embodiment, the third traction member 510 is made of steel wire. Of course, in other embodiments, the third traction member 510 can also be made of other materials. The drift operating member 520 can be operated to cause the driving member 460 to overcome the force of the fifth reset member 455 through the third traction member 510 and rotate relative to the driver support rod 300 until the first driving rib 431 and the second driving rib 432 simultaneously push against the first driving block 421 and the second driving block 422, respectively. In this way, the first driving block 421 and the second driving block 422 are both in a position closer to the first pivot point M (i.e., a lower position). At this time, the first traction member 441 and the second traction member 442 are both tightened. At the same time, the first traction member 441 pulls the first directional pin 131 to overcome the elastic force of the third reset member 453 and move along the fourth direction D4. The second traction member 442 pulls the second directional pin 231 to overcome the elastic force of the fourth reset member 454 and move along the fourth direction D4, so that the first directional mechanism 130 and the second directional mechanism 230 are both released, so that the child stroller can realize the drift function.
[0070] In yet another embodiment, Figures 1 to 13 The corresponding embodiment may also include a drifting drive mechanism 500 and a fifth reset member 455. The user operates the drifting operating member 520, causing the driving member 460 to overcome the force of the fifth reset member 455 and rotate relative to the rider support rod 300 until the first driving rib 431 and the second driving rib 432 no longer push against the first driving block 421 and the second driving block 422. In this manner, the first driving block 421 and the second driving block 422 are both located farther away from the first pivot point M (i.e., further upward). At this point, the first pulling member 441 and the second pulling member 442 are pulled upward, releasing the first and second orienting mechanisms 130 and 230, thereby enabling the stroller to achieve the drifting function.
[0071] The above-mentioned child stroller has at least the following technical effects:
[0072] The rider support rod 300 can rotate relative to the first traveling assembly 100 or the second traveling assembly 200 to achieve a reversing function. When the rider support rod 300 rotates to the same side as the first traveling assembly 100, the orientation adjustment mechanism 400 can be used to orient the first wheel 120 and de-orient the second wheel 220. When the rider support rod 300 rotates to the same side as the second traveling assembly 200, the orientation adjustment mechanism 400 can be used to orient the second wheel 220 and de-orient the first wheel 120. In other words, when the rider support rod 300 changes direction, the orientation adjustment function provided between the first traveling assembly 100, the second traveling assembly 200, and the rider support rod 300 facilitates the pushing of the stroller after the reversal. The orientation adjustment function of the orientation adjustment mechanism 400 is primarily achieved through the first and second drive blocks 421, 422, resulting in a simple structure and easy implementation. The above-mentioned child stroller can realize the function of adjusting the orientation of the wheels while reversing the direction of the rider support rod 300 with a simple structure, thereby reducing the manufacturing cost of the child stroller.
[0073] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0074] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
