Description

Technical Field

[0001] The present invention relates to the technical field of child carriers, and particularly to a baby stroller. Background Art

[0002] Generally, a baby stroller on the market is provided with a rider reversing mechanism, so that the direction of the child can be adjusted as needed. For example, the child can face the parent for interaction or the child can face away from the parent to enjoy the scenery along the way. To facilitate the movement of the baby stroller, it is generally set that when the rider is on the rear wheel side, the rear wheels are oriented and the front wheels are de-oriented, and when the rider is on the front wheel side, the front wheels are oriented and the rear wheels are de-oriented. However, the structure for realizing this function is generally complex, with high manufacturing difficulty and high manufacturing cost. Summary of the Invention

[0003] The present invention provides a baby stroller, which can realize the function of adjusting the orientation of wheel members while reversing the rider with a simple structure, thereby reducing the manufacturing cost of the baby stroller.

[0004] The present invention provides a baby stroller, including a first traveling assembly, a second traveling assembly, a rider support rod, and an orientation adjustment mechanism. The first traveling assembly includes a first wheel member. The second traveling assembly includes a second wheel member. The rider support rod rotates relative to the first traveling assembly or the second traveling assembly. The orientation adjustment mechanism includes a first driving block and a second driving block. Wherein, when the rider support rod rotates to the same side as the first traveling assembly, the first driving block drives the first wheel member to be oriented, and the second driving block drives the second wheel member to be de-oriented; when the rider support rod rotates to the same side as the second traveling assembly, the second driving block drives the second wheel member to be oriented, and the first driving block drives the first wheel member to be de-oriented.

[0005] In the above baby stroller, the rider support rod can rotate relative to the first traveling assembly or the second traveling assembly, so that the reversing function can be realized. When the rider rotates to the same side as the first traveling assembly, the orientation of the first wheel member and the de-orientation of the second wheel member can be realized through the orientation adjustment mechanism. When the rider rotates to the same side as the second traveling assembly, the orientation of the second wheel member and the de-orientation of the first wheel member can be realized through the orientation adjustment mechanism. That is, when the rider reverses, the orientation adjustment function provided between the first traveling assembly, the second traveling assembly, and the rider support rod can facilitate the pushing of the baby stroller after reversing. The orientation adjustment function of the orientation adjustment mechanism is mainly realized by the first driving block and the second driving block, with a simple structure and easy implementation. The above baby stroller can realize the function of adjusting the orientation of wheel members while reversing the rider with a simple structure, thereby reducing the manufacturing cost of the baby stroller.

[0032] As Figures 1 to 3 and Figure 18 As shown in the figure, an embodiment of the present invention provides a baby stroller, which includes a first traveling assembly 100, a second traveling assembly 200, a rider support rod 300, an orientation adjustment mechanism 400, and a drift driving mechanism 500. The baby stroller can realize the function of reversing the rider and adjusting the wheel orientation with a simple structure, thereby reducing the manufacturing cost of the baby stroller.

[0033] Specifically, as Figure 1 , Figure 12 and Figure 13 shown, the first traveling assembly 100 includes a first wheel support rod 110, a first wheel assembly 120, a first orientation mechanism 130, and a first rotating shaft 140.

[0034] As Figure 1 , Figure 12 and Figure 13As shown, the first wheel support rod 110 is pivotally connected to the first wheel member 120. Specifically, one end of the first rotating shaft 140 is fixed to the first wheel support rod 110, and the first wheel member 120 is pivotally connected to the other end of the first rotating shaft 140. Of course, in other embodiments, it is also possible that one end of the first rotating shaft 140 is fixed to the first wheel member 120, and the first wheel support rod 110 is pivotally connected to the other end of the first rotating shaft 140, and no limitation is made thereto. The first wheel member 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 installed in the first wheel frame 121.

[0035] As Figure 1 , Figure 12 and Figure 13 shown, the first orientation mechanism 130 includes a first orientation pin 131 movably arranged on the first wheel support rod 110 and a first orientation groove 132 arranged on the first wheel frame 121. The first orientation pin 131 is inserted into the first orientation groove 132 to lock the first orientation mechanism 130. At this time, the first wheel member 120 maintains a certain direction relative to the first wheel support rod 110. The first orientation pin 131 disengages from the first orientation groove 132 to unlock the first orientation mechanism 130. At this time, the first wheel member 120 can rotate 360 degrees relative to the first wheel support rod 110. Of course, the first orientation mechanism 130 can also be in other forms, as long as it can be locked to achieve the orientation of the first wheel member 120 and can be unlocked to achieve the release of the orientation of the first wheel member 120.

[0036] Specifically, as Figure 1 , Figure 10 and Figure 11 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] As Figure 1 , Figure 10 and Figure 11 shown, the second wheel support rod 210 is pivotally connected to the second wheel member 220. Specifically, one end of the second rotating shaft 240 is fixed to the second wheel support rod 210, and the second wheel member 220 is pivotally connected to the other end of the second rotating shaft 240. Of course, in other embodiments, it is also possible that one end of the second rotating shaft 240 is fixed to the second wheel member 220, and the second wheel support rod 210 is pivotally connected to the other end of the second rotating shaft 240. The second wheel member 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 installed in the second wheel frame 221.

[0038] As Figure 1 ,Figure 10 and Figure 11 As shown, the second orientation mechanism 230 includes a second orientation pin 231 movably arranged on the second wheel support rod 210 and a second orientation slot 232 arranged 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, and the second wheel component 220 maintains a certain direction 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, and the second wheel component 220 can rotate 360 degrees relative to the second wheel support rod 210. Of course, the second orientation mechanism 230 can also be in other forms, as long as it can be locked to achieve the orientation of the second wheel component 220 and can be released to achieve the deorientation of the second wheel component 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, 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 The sixth direction D6 is in the process.

[0041] Specifically, 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 rider 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 rider support bar 300 is rotated 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 housing 410, a first drive block 421, a second drive block 422, a first drive rib 431, a second drive 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, as Figures 1 to 3 shown, the fixed housing 410 includes a first fixed seat 411, a second fixed seat 412, and a connecting seat 413. The first fixed seat 411 is pivotally connected to the first traveling assembly 100, the second fixed seat 412 is fixed to the second traveling assembly 200, and the first fixed seat 411 and the second fixed seat 412 enclose an accommodation space. The first fixed seat 411 is generally in an elliptical sheet-like structure. The second fixed seat 412 includes a fixed seat body 412a and a connecting member 412b connected to each other. The fixed seat body 412a is in an elliptical disk-like structure matching the first fixed seat 411, and the connecting member 412b is generally in a sleeve-like shape so as to be sleeved on one end of the second wheel support rod 210 away from the second wheel member 220. The connecting seat 413 is fixed to one end of the first wheel support rod 110 away from the first wheel member 120. The connecting seat 413 is provided with a pivot shaft 413a, and the pivot shaft 413a sequentially passes through the first fixed seat 411 and the fixed seat body 412a to achieve coaxial pivoting among the three. Please refer to Figure 7 together. The connecting seat 413, the first fixed seat 411, and the fixed seat body 412a are pivotally connected to a first pivot point M. The rider support rod 300 is pivotally connected to a surface of the second fixed seat 412 facing away from the first fixed seat 411, and the rider support rod 300 and the second fixed seat 412 are pivotally connected to a second pivot point N. The second fixed seat 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 fixed seat 411. In this embodiment, the first pivot point M is located in a 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 connecting seat 413 is made of a plastic material. Of course, in other embodiments, the connecting seat 413 may also be made of other materials.

[0045] Furthermore, as Figures 6 to 9As shown, the first driving block 421 and the second driving block 422 are movably arranged in the fixed housing 410, that is, located in the accommodation space. Specifically, a long first guide groove 421a is provided on the first driving block 421, and the first guide post 411a is inserted into the first guide groove 421a. The first guide groove 421a and the first guide post 411a cooperate with each other so that the first driving block 421 can reciprocate along the extending direction of the first guide groove 421a, that is, the first direction D1 and the fifth direction D5. A long second guide groove 422a is provided on the second driving block 422, and the second guide post 411b is inserted into the second guide groove 422a. The second guide groove 422a and the second guide post 411b cooperate with each other so that the second driving block 422 can reciprocate along the extending direction of the second guide groove 422a, that is, the first direction D1 and the fifth direction D5. Of course, the first driving block 421 and the second driving block 422 can also be movably arranged in the fixed housing 410 in other ways. The first direction D1 and the fifth direction D5 are opposite to each other.

[0046] Specifically, as Figure 3 shown, a through hole 412c communicating with the accommodation space is provided on the second fixed seat 412. The first driving block 421 can move along the fifth direction D5 to pass through the through hole 412c, and the second driving block 422 can move along the fifth direction D5 to pass through the through hole 412c. In this embodiment, there are two through holes 412c, which can respectively allow the first driving block 421 and the second driving block 422 to pass through. The orientation adjustment mechanism 400 further includes a separator 411c, and the separator 411c is located between the first driving block 421 and the second driving block 422 for separating the first driving block 421 and the second driving block 422. In other embodiments, there can also be one through hole 412c as long as it can allow the first driving block 421 and the second driving block 422 to pass through.

[0047] Furthermore, as Figures 2 to 5 shown, the first driving rib 431 and the second driving rib 432 are arranged on the rider support rod 300, and a track 412d is provided on the second fixed seat 412. The first driving rib 431 and the second driving rib 432 can move along the track 412d. 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 9, the first driving block 421 is located between the first driving rib 431 and the first orientation mechanism 130. The rider support rod 300 rotates to the same side as the first traveling assembly 100. The first driving rib 431 pushes the first driving block 421 counterclockwise to move in the first direction D1, locking the first orientation mechanism 130. The second driving block 422 is located between the second driving rib 432 and the second orientation mechanism 230. The rider support rod 300 rotates to the same side as the second traveling assembly 200. The second driving rib 432 pushes the second driving block 422 clockwise to move in the first direction D1, locking the second orientation mechanism 230.

[0048] In this embodiment, both the first driving rib 431 and the second driving rib 432 are 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 to prevent the first driving rib 431 from interfering with the movement of the second driving block 422 when pushing the first driving block 421.

[0049] Furthermore, as Figures 6 to 13 shown, both ends of the first traction member 441 are respectively connected to the first driving block 421 and the first orientation mechanism 130. Specifically, both ends of the first traction member 441 are respectively connected to one end of the first driving block 421 close to the first pivot point M and one end of the first orientation pin 131 close to the first pivot point M, that is, the first traction member 441 extends along the direction from the first driving block 421 to the first orientation pin 131. In this way, when the first driving block 421 moves along the fifth direction D5, it can drive the first orientation pin 131 to move along the fourth direction D4 through the first traction member 441, causing the first orientation pin 131 to disengage from the first orientation groove 132 and unlocking the first orientation mechanism 130.

[0050] Similarly, both ends of the second traction member 442 are respectively connected to the second driving block 422 and the second orientation mechanism 230. Specifically, both ends of the second traction member 442 are respectively connected to one end of the second driving block 422 close to the first pivot point M and one end of the second orientation pin 231 close to the first pivot point M, that is, the second traction member 442 extends along the direction from the second driving block 422 to the second orientation mechanism 230. In this way, when the second driving block 422 moves along the fifth direction D5, it can drive the second orientation pin 231 to move along the fourth direction D4 through the second traction member 442, causing the second orientation pin 231 to disengage from the second orientation groove 232 and unlocking the second orientation mechanism 230.

[0051] In this embodiment, both the first traction member 441 and the second traction member 442 are steel wires. Of course, in other embodiments, the first traction member 441 and the second traction member 442 can also be made of other materials.

[0052] Furthermore, as Figures 6 to 9As shown, two ends of the first reset member 451 are respectively abutted against the fixed housing 410 and the first driving block 421. Specifically, the first reset member 451 is disposed substantially along the first direction D1. One end of the first reset member 451 is disposed at one end of the first driving block 421 close to the first pivot point M, and the other end of the first reset member 451 is abutted against the fixed housing 410. The first reset member 451 constantly moves the first driving block 421 in the direction of unlocking the first orientation mechanism 130, that is, the first reset member 451 constantly moves the first driving block 421 in the fifth direction D5. Thus, when the rider support rod 300 rotates from the same side as the first traveling assembly 100 to the same side as the second traveling assembly 200, and the first driving rib 431 changes from pushing against the first driving block 421 to not pushing 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 reset member 451, so as to drive the first orientation pin 131 to move in the fourth direction D4 through the first traction member 441 to disengage from the first orientation groove 132, so that the first orientation mechanism 130 is unlocked. The first reset member 451 can be a spring, an elastic rubber column, etc.

[0053] Similarly, as Figures 6 to 9 shown, two ends of the second reset member 452 are respectively abutted against the fixed housing 410 and the second driving block 422. Specifically, the second reset member 452 is disposed substantially along the first direction D1. One end of the second reset member 452 is disposed at one end of the second driving block 422 close to the first pivot point M, and the other end of the second reset member 452 is abutted against the fixed housing 410. The second reset member 452 constantly moves the second driving block 422 in the direction of unlocking the second orientation mechanism 230, that is, the second reset member 452 constantly moves the second driving block 422 in the fifth direction D5. Thus, when the rider support rod 300 rotates from the same side as the second traveling assembly 200 to the same side as the first traveling assembly 100, and the second driving rib 432 changes from pushing against the second driving block 422 to not pushing 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 reset member 452, so as to drive the second orientation pin 231 to move in the fourth direction D4 through the second traction member 442 to disengage from the second orientation groove 232, so that the second orientation mechanism 230 is unlocked. The second reset member 452 can be a spring, an elastic rubber column, etc.

[0054] Furthermore, as Figure 12 and Figure 13As shown, the two ends of the third reset member 453 are respectively abutted against the first wheel support rod 110 and the first positioning pin 131. The third reset member 453 always locks the first orientation mechanism 130, that is, the third reset member 453 always makes the first positioning pin 131 move towards the direction of the first orientation groove 132. The elastic coefficient of the third reset member 453 is smaller than that of the first reset member 451. Thus, when the first driving rib 431 does not push against the first driving block 421, the first driving block 421 can move along the fifth direction D5 under the elastic force of the first reset member 451, overcoming the elastic force of the third reset member 453, so as to realize the unlocking of the first orientation mechanism 130. When the first driving rib 431 pushes against the first driving block 421, causing the first driving block 421 to move along the fifth direction D5 and the first reset member 451 to be compressed, the first positioning pin 131 moves into the first orientation groove 132 under the elastic force of the third reset member 453, so as to realize the locking of the first orientation mechanism 130. The third reset member 453 can be a spring, an elastic rubber column, etc.

[0055] Similarly, as Figure 10 and Figure 11 shown, the two ends of the fourth reset member 454 are respectively abutted against the second wheel support rod 210 and the second positioning pin 231. The fourth reset member 454 always locks the second orientation mechanism 230, that is, the fourth reset member 454 always makes the second positioning pin 231 move towards the direction of the second orientation groove 232. The elastic coefficient of the fourth reset member 454 is smaller than that of the second reset member 452. Thus, when the second driving rib 432 does not push against the second driving block 422, the second driving block 422 can move along the fifth direction D5 under the elastic force of the second reset member 452, overcoming the elastic force of the fourth reset member 454, so as to realize the unlocking of the second orientation mechanism 230. When the second driving rib 432 pushes against the second driving block 422, causing the second driving block 422 to move along the first direction D1 and the second reset member 452 to be compressed, the second positioning pin 231 moves into the second orientation groove 232 under the elastic force of the fourth reset member 454, so as to realize the locking of the second orientation mechanism 230. The fourth reset member 454 can be a spring, an elastic rubber column, etc.

[0056] The specific working principle of the orientation adjustment mechanism 400 in this embodiment is as follows:

[0057] When the rider support rod 300 rotates to the same side as the first traveling assembly 100, as Figure 6 and Figure 7As shown, the first driving rib 431 pushes against the first driving block 421, causing the first driving block 421 to be in a position closer to the first pivot point M (i.e., a lower position). At this time, the first traction member 441 is relaxed, and the first orientation pin 131 moves in the third direction D3 under the elastic force of the third reset member 453, so that the first orientation pin 131 is inserted into the first orientation groove 132 and the first orientation mechanism 130 is locked. At the same time, the un-pushed second driving block 422 is in a position farther from the first pivot point M (i.e., a higher position) under the elastic force of the second reset member 452. At this time, the second traction member 442 is tightened, and the second orientation pin 231 moves in the fourth direction D4 under the pulling force of the second traction member 442, overcoming the elastic force of the fourth reset member 454, so that the second orientation pin 231 disengages from the second orientation groove 232 and the second orientation mechanism 230 is unlocked. The third direction D3 is opposite to the fourth direction D4.

[0058] Similarly, when the rider support rod 300 rotates to the same side as the second traveling assembly 200, as Figure 8 and Figure 9 shown, the second driving rib 432 pushes against the second driving block 422, causing the second driving block 422 to be in a position closer to the first pivot point M (i.e., a lower position). At this time, the second traction member 442 is relaxed, and the second orientation pin 231 moves in the third direction D3 under the elastic force of the fourth reset member 454, so that the second orientation pin 231 is inserted into the second orientation groove 232 and the second orientation mechanism 230 is locked. At the same time, the un-pushed first driving block 421 is in a position farther 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 traction member 441 is tightened, and the first orientation pin 131 moves in the fourth direction D4 under the pulling force of the first traction member 441, overcoming the elastic force of the third reset member 453, so that the first orientation pin 131 disengages from the first orientation groove 132 and the first orientation mechanism 130 is unlocked.

[0059] In another embodiment, as Figures 14 to 17 shown, the orientation adjustment mechanism 400 includes a fixed housing 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. The structure of the orientation adjustment mechanism 400 in this embodiment is basically the same as that of the orientation adjustment mechanism 400 in the corresponding Figures 1 to 13 embodiment, the difference is that;

[0060] First, as Figures 14 to 17As shown, one end of the first traction member 441 is connected to the first orientation mechanism 130 (specifically, connected to the first orientation pin 131), and the other end bypasses the partition member 411c and is connected to the first driving block 421. In this way, the first orientation pin 131, the first traction member 441, the first driving block 421, and the partition member 411c form a structure similar to a pulley, such that the moving direction of the first orientation pin 131 is opposite to the moving direction of the first driving block 421. Thus, 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 realizing the unlocking of the first orientation mechanism 130.

[0061] Similarly, as Figures 14 to 17 shown, one end of the second traction member 442 is connected to the second orientation mechanism 230, specifically connected to the second orientation pin 231, and the other end bypasses the partition member 411c and is connected to the second driving block 422. In this way, the second orientation pin 231, the second traction member 442, the second driving block 422, and the partition member 411c form a structure similar to a pulley, such that the moving direction of the second orientation pin 231 is different from the moving direction of the second driving block 422. Thus, when the second driving block 422 moves along the first direction D1, it can drive the second orientation pin 231 to move along the fourth direction D4, thereby realizing the unlocking of the second orientation mechanism 230.

[0062] Secondly, as Figure 14 and Figure 15 shown, the rider support rod 300 rotates to the same side as the first traveling assembly 100, and the second driving rib 432 pushes the second driving block 422 along the first direction D1 to make the second orientation mechanism 230 in an unlocked state, while the first driving block 421 is not pushed by the first driving rib 431, so that the first orientation mechanism 130 is in a locked state. As Figure 16 and Figure 17 shown, the rider support rod 300 rotates to the same side as the second traveling assembly 200, and the first driving rib 431 pushes the first driving block 421 along the first direction D1 to make the first orientation mechanism 130 in an unlocked state, while the second driving block 422 is not pushed by the second driving rib 432, so that the second orientation mechanism 230 is in a locked state.

[0063] In addition, as Figures 14 to 17As shown, in this embodiment, since the first alignment pin 131 moves in the opposite direction to the first driving block 421, when the first driving rib 431 does not push against the first driving block 421, the first driving block 421 can move along the fifth direction D5 under the elastic force of the first reset member 451. At this time, the first traction member 441 is relaxed, and at the same time, the first alignment pin 131 moves along the third direction D3 under the elastic force of the third reset member 453, so as to realize the locking of the first alignment mechanism 130. Therefore, in this embodiment, the elastic coefficient of the third reset member 453 does not need to be less than the elastic coefficient of the first reset member 451.

[0064] Similarly, as Figures 14 to 17 shown, in this embodiment, since the second alignment pin 231 moves in the opposite direction to the second driving block 422, when the second driving rib 432 does not push against the second driving block 422, the second driving block 422 can move along the fifth direction D5 under the elastic force of the second reset member 452. At this time, the second traction member 442 is relaxed, and at the same time, the second alignment pin 231 moves along the third direction D3 under the elastic force of the fourth reset member 454, so as to realize the locking of the first alignment mechanism 130. Therefore, in this embodiment, the elastic coefficient of the fourth reset member 454 does not need to be less than the elastic coefficient of the second reset member 452.

[0065] The specific working principle of the alignment adjustment mechanism 400 in this embodiment is as follows:

[0066] When the rider support rod 300 rotates to the same side as the first traveling assembly 100, as Figure 14 and Figure 15 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 reset member 452 and is in a position closer to the first pivot point M (i.e., a lower position). At this time, the second traction member 442 is tightened, and at the same time, the second traction member 442 pulls the second alignment pin 231 to move along the fourth direction D4 against the elastic force of the fourth reset member 454, so that the second alignment pin 231 disengages from the second alignment groove 232 and the second alignment mechanism 230 is unlocked. At the same time, the un-pushed first driving block 421 is in a position farther 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 traction member 441 is relaxed, and the first alignment pin 131 moves in the third direction D3 under the elastic force of the third reset member 453, so that the first alignment pin 131 is inserted into the first alignment groove 132 and the first alignment mechanism 130 is locked.

[0067] Similarly, as Figure 16 and Figure 17As shown, when the rider support rod 300 rotates to the same side as the second traveling assembly 200, the first driving rib 431 pushes against the first driving block 421, and the first driving block 421 overcomes the elastic force of the first reset member 451 and is in a position closer to the first pivot point M (i.e., a lower position). At this time, the first traction member 441 is tightened, and at the same time, the first traction member 441 pulls the first positioning pin 131 to move along the fourth direction D4 against the elastic force of the third reset member 453, so that the first positioning pin 131 disengages from the first positioning groove 132 and the first positioning mechanism 130 is unlocked. At the same time, the un-pushed second driving block 422 is in a position farther from the first pivot point M (i.e., a higher position) under the elastic force of the second reset member 452. At this time, the second traction member 442 is relaxed, and the second positioning pin 231 moves in the third direction D3 under the elastic force of the fourth reset member 454, so that the second positioning pin 231 is inserted into the second positioning groove 232 and the second positioning mechanism 230 is locked.

[0068] In another embodiment, as Figures 14 - 17 corresponding to the embodiment, please also refer to Figures 18 to 24 , the orientation adjustment mechanism 400 further includes a driving member 460 and a fifth reset member 455. The driving member 460 is generally in an annular structure, and the first driving rib 431 and the second driving rib 432 are provided on the upper ring of the driving member 460. The driving member 460 is pivotally connected to the rider support rod 300, and both the first driving rib 431 and the second driving rib 432 can move on 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. When the rider support rod 300 changes direction, the driving member 460 is fixed relative to the rider support rod 300. The two ends of the fifth reset member 455 abut against the driving member 460 and the rider support rod 300 respectively, and the fifth reset member 455 always makes the driving member 460 and the rider support rod 300 relatively fixed. The fifth reset member 455 can be a spring, an elastic rubber column, etc.

[0069] Specifically, as Figures 18 to 22As shown, the drift driving mechanism 500 includes a third traction member 510 and a drift operating member 520. Both ends of the third traction member 510 are respectively connected to the drift operating member 520 and the driving member 460. In this embodiment, the third traction members 510 are all steel wires. Of course, in other embodiments, the third traction members 510 can also be made of other materials. The drift operating member 520 can be operated to cause the driving member 460 to rotate relative to the rider support rod 300 through the third traction member 510, overcoming the acting force of the fifth reset member 455, so that the first driving rib 431 and the second driving rib 432 respectively and simultaneously abut against the first driving block 421 and the second driving block 422. Thus, both the first driving block 421 and the second driving block 422 are in positions closer to the first pivot point M (i.e., lower positions). At this time, both the first traction member 441 and the second traction member 442 are tightened. At the same time, the first traction member 441 pulls the first orientation pin 131 to move along the fourth direction D4 against the elastic force of the third reset member 453, and the second traction member 442 pulls the second orientation pin 231 to move along the fourth direction D4 against the elastic force of the fourth reset member 454, unlocking both the first orientation mechanism 130 and the second orientation mechanism 230, so that the stroller can achieve the drift function.

[0070] In yet another embodiment, Figures 1 to 13 For the corresponding embodiment, a drift driving mechanism 500 and a fifth reset member 455 can also be provided. The user operates the drift operating member 520 to cause the driving member 460 to rotate relative to the rider support rod 300, overcoming the acting force of the fifth reset 455, so that the first driving rib 431 and the second driving rib 432 do not abut against the first driving block 421 and the second driving block 422. Thus, both the first driving block 421 and the second driving block 422 are in positions farther from the first pivot point M (i.e., higher positions). At this time, the first traction member 441 and the second traction member 442 are tightened upward, unlocking both the first orientation mechanism 130 and the second orientation mechanism 230, so that the stroller can achieve the drift function.

[0071] The above 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, thereby realizing the commutation function. When the rider support rod 300 rotates to the same side as the first traveling assembly 100, the orientation of the first wheel member 120 can be realized through the orientation adjustment mechanism 400 and the orientation of the second wheel member 220 can be released. When the rider support rod 300 rotates to the same side as the second traveling assembly 200, the orientation of the second wheel member 220 can be realized through the orientation adjustment mechanism 400 and the orientation of the first wheel member 120 can be released. That is, when the rider support rod 300 commutes, the orientation adjustment function provided among the first traveling assembly 100, the second traveling assembly 200 and the rider support rod 300 can facilitate the pushing of the stroller after commutation. The orientation adjustment function of the orientation adjustment mechanism 400 is mainly realized by the first driving block 421 and the second driving block 422, with a simple structure and easy implementation. The above stroller can realize the function of adjusting the wheel orientation while commuting the rider support rod 300 with a simple structure, thereby reducing the manufacturing cost of the stroller.

[0073] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
