As shown in fig. 1 to 12, a pedal adjusting mechanism of a child seat comprises a seat part 1, a pedal 2 with an upper side pivoted to a front side of the seat part 1, wherein the pedal 2 can be switched between a first angle position and a second angle position relative to the seat part 1, the seat also comprises a gear 3 which is rotatably arranged between the upper side of the pedal 2 and the seat part 2, and a locking device movably connected with the seat part 1, and the gear 3 can be driven to rotate upwards when the pedal 2 rotates upwards; and the gear 3 and the locking means are arranged such that, when the step 2 is in the first angular position, the locking means cooperate with the step 2 such that the step 2 cannot rotate downwards relative to the seat 1; the pedal 2 is rotated upwards from the first angular position, and the gear 3, which rotates upwards with the pedal 2, can drive the locking means to move out of engagement with the pedal 2, so that the pedal 2 can be rotated downwards again to the second angular position.

In this embodiment, when the step 2 is rotated up to the third angular position, the locking device is completely disengaged from the step 2, and the step 2 can be rotated down to the second working position.

Preferably, the step 2 at the second angular position can also rotate upwards to the third angular position and then rotate downwards, and when the step 2 rotates downwards to the first angular position, the locking device is matched with the gear 3 and the step 2 again, so that the step 2 cannot rotate downwards.

The upper side of the pedal 2 and the gear 3 are pivoted with the sitting portion 1 through a pivot (not shown) extending leftwards and rightwards.

The upper side of the pedal 2 and the riding part 1 are respectively provided with a first limiting part and a second limiting part, when the pedal 2 is positioned at a second angle position, one side of the first limiting part is matched with the second limiting part, and the pedal 2 can not rotate downwards relative to the riding part 1.

In this embodiment, the first limiting portion is an arc-shaped limiting groove 20 formed on the pedal 2, and the second limiting portion is a limiting projection 11 formed on the seat portion 1, where the limiting projection 11 extends into the arc-shaped limiting groove 20; when the pedal 2 is located at the second angular position, one end of the arc-shaped limiting groove 20 abuts against the limiting bump 11, and the pedal 2 cannot rotate downward relative to the seat 1. When the pedal 2 rotates relative to the seat 1, the limit projection 11 moves relative to the arc-shaped limit groove 20. The pedal 2 rotates upwards, one end 201 of the arc-shaped limit groove 20 is far away from the limit bump 11, and when the pedal 2 rotates to a third angle, the other end 202 of the arc-shaped limit groove 20 abuts against the limit bump 11, and the pedal 2 cannot rotate upwards relative to the sitting portion 1. In this way, the limiting projection 11 and the arc limiting groove 20 are arranged, so that the limit of the upper and lower rotation angle range of the pedal 2 is realized.

The upper side of the pedal 2 is provided with a receiving cavity 21 in a concave manner toward the middle of one side of the riding part 1, the gear 3 is relatively rotatably positioned in the receiving cavity 21 of the pedal 2, and the gear 3 is arranged to be immovable in the axial direction relative to the pedal 2 and the riding part 1, i.e. immovable in the left-right direction relative to the pedal 2 and the riding part 1. In the present embodiment, the end face of the gear 3 facing the sitting portion 1 is flush with the end face of the step 2 facing the sitting portion 1; therefore, after the step 2 and the gear 3 are pivoted to the seat 1, the upper end surface of the step 2 is bonded to the seat 1, and therefore the gear 3 cannot move laterally with respect to the step 2 and the seat 1, and can rotate only with respect to the step 2 and the seat 1 or rotate together with the step 2 when the step 2 rotates upward.

In this embodiment, the limit bump 11 is disposed on the sitting portion 1, the arc-shaped limit groove 20 is disposed on the pedal 2, and the arc-shaped limit groove 20 is disposed outside the accommodating cavity 21 and is communicated with the accommodating cavity 21. When the pedal 2 is at the first angle position, one side of the locking device extends into the arc-shaped limiting groove 20 and abuts against one end of the arc-shaped limiting groove 20 to be matched with the pedal, so that the pedal 2 cannot rotate downwards.

The locking device comprises a locking member 4 axially movably connected to the seat 1, a first elastic member 5 arranged between the locking member 4 and the seat 1. In this embodiment, the seat 1 is provided with a first mounting groove 12 on a side facing the step 2, and the locking member 4 is axially movably disposed in the first mounting groove 12. The first mounting groove 12 and the limit bump 11 are arranged at intervals. The first elastic member 5 is configured as a compression spring, and is disposed between the locking member 4 and the bottom wall of the first mounting groove 12.

The gear 3 is provided with a plurality of groups of locking grooves in turn towards the circumferential direction of one side of the riding part 1, each group of locking grooves 32 comprises a first locking groove 321 and a second locking groove 322 which are arranged in turn in the circumferential direction, one side of each of the first locking groove 321 and the second locking groove 322 can be in blocking fit with the locking piece 4, and the other side of each of the first locking groove 321 and the second locking groove 322 can be in inclined plane fit with the locking piece 4. In this embodiment, one side of each of the first locking groove 321 and the second locking groove 322 is set as a stop surface 3211, 3221 (as shown in fig. 6 and 7), and at least one side of each of the first locking groove 321 and the second locking groove 322 is also set as a slant surface 3212, 3222 (as shown in fig. 6 and 7); when the locking piece 4 extends into the first locking groove 321 or the second locking groove 322 and abuts against the stop surfaces 3211 and 3221, the gear 3 is blocked by the locking piece 4 and cannot rotate together with the downward rotating pedal 2; when the pedal 2 rotates upward and drives the gear 3 to rotate together, the inclined surfaces 3212, 3222 of the first locking groove 321 or the second locking groove 322 drive the locking piece 4 to move in the direction toward the seat portion 1, specifically, into the first mounting groove 12.

In this embodiment, when the pedal 2 is at the first angular position, one side of the locking member 4 extends into the first locking groove 321 and abuts against the stop surface thereof, and the locking member 4 also extends into the pedal 2 to cooperate with the pedal 2, i.e. extends into the arc-shaped limit groove 20 of the pedal 2 and abuts against one end of the arc-shaped limit groove 20, so that the pedal 2 cannot rotate downward.

Preferably, when the pedal 2 rotates upward from the first angle position to the third angle, the locking member 4 is completely separated from the pedal 2 and the first locking groove 321 and is opposite to the second locking groove 322 of the same set of locking grooves, and under the action of the first elastic member 5, one side of the locking member 4 extends into the second locking groove 322 and contacts with the stop surface thereof. When the step 2 is rotated upward from the second angular position to the third angle, the locking piece 4 is completely disengaged from the second locking groove 322 and is opposed to the first locking groove 321 of the adjacent group of locking grooves.

In this embodiment, the locking member 4 includes a main body 40 and a locking portion 41, and the locking portion 41 is disposed at one end of the main body 40 facing the pedal 2 (as shown in fig. 4).

Preferably, the first locking groove 321 is configured such that the maximum groove depth (in this embodiment, the groove depth at the position of the stop surface) is greater than the length of the locking portion 41, and the thickness of the main body 40 is greater than the thickness of the locking portion 41, and the thickness of the main body 40 is also greater than the height of the first locking groove 321. So set up, when step 2 is in first angular position, locking piece 4 is relative with first locking groove 321 and first locking groove 321 communicates with each other with arc spacing recess 20, under the effect of first elastic component 5, locking piece 4 moves towards the direction towards gear 3, locking part 41 of locking piece 4 stretches into first locking groove 321, locking piece main part 40 stretches into first locking groove 321 towards one side of gear 3 and is in abutment with its backstop face (as shown in fig. 10), the part that this side of main part 40 lies in outside first locking groove 321 stretches into step 2 in cooperation with step 2, stretch into in the arc spacing recess 20 and be in abutment with one end of arc spacing recess 20, step 2 can not rotate down. And because in the first angular position, the locking piece main body 40 is abutted against one end 201 in the arc-shaped limiting groove 20, so that more powerful support can be formed on the pedal 2, and the pedal 2 can bear larger weight in the first angular position and cannot rotate downwards, so that the use of children is safer and more reliable.

The second locking groove 322 is provided such that its maximum groove depth (in this embodiment, the groove depth at the position of its stop surface) is not greater than the length of the locking portion 41. When the pedal 2 rotates upwards from the first angle position to the third angle position, the locking piece 4 is completely separated from the pedal 2 and the first locking groove 321 and is opposite to the second locking groove 322 of the same group of locking grooves, the locking piece moves towards the direction of the gear 3 under the action of the first elastic piece 5, and only the locking part 41 stretches into the second locking groove 322 and abuts against the stop surface (as shown in fig. 11), so that the main body 40 cannot stretch into the second locking groove 322. So configured, when the locking portion 41 is positioned in the second locking groove 322, the locking member 4 has a connection relationship with the gear 3 only, and has no connection relationship with the step 2, i.e., completely disengages from the engagement with the step 2, so that the step 2 can be rotated downward.

When the step 2 is rotated upward from the second angular position to the third angle, the locking piece 4 is completely disengaged from the second locking groove 322 and is opposed to the first locking groove 321 of the adjacent group of locking grooves.

Preferably, the width of the main body 40 is also larger than the width of the locking portion 41. Thus, in the first angular position, the supporting force of the locking member main body 40 on the pedal 2 is larger, so that the pedal 2 can bear larger weight without rotating downwards in the first angular position, and the use of children is safer and more reliable.

Further, when the body 40 of the locking member 4 is inserted into the first locking groove 321 and abuts against the stop surface 3211 of the first locking groove 321, the locking portion 41 contacts the inclined surface 3212 of the first locking groove 321. So that when the gear 3 is rotated together by the step 2 rotated upward, the inclined surface of the first locking groove 321 pushes the locking piece 4 into the first mounting groove 12 by pushing the locking portion 41.

The shifting device comprises a shifting piece 6 which is connected to the upper side of the pedal 2 in an axially movable manner, and a second elastic piece 7 which is arranged between the shifting piece 6 and the pedal 2. In this embodiment, a second mounting groove 22 (as shown in fig. 5) is disposed on the upper side of the pedal 2 on the side facing the sitting portion 1, and one side of the striking member 6 is axially movably disposed in the second mounting groove 22, and the second mounting groove 22 is disposed to communicate with the accommodating cavity 21, so that the striking member 6 can extend into the accommodating cavity 21 to cooperate with the gear 3. The second elastic member 7 is configured as a compression spring, and is disposed between the toggle member 6 and the bottom wall of the second mounting groove 22.

The gear 3 is provided with the multiunit and stirs the groove towards the one side circumference of taking portion 1, and each group stirs the groove and all includes the circumference and sets gradually the first groove 311 of stirring that can supply stirring piece 6 to stretch into and stir the groove 312 with the second, when stirring piece 6 and first groove 311 or the second groove 312 of stirring are relative, under the effect of second elastic component 7, stir piece 6 and move towards the direction of gear 3 and one side stretches into in the first groove 311 or the second groove 312 of stirring.

The first toggle slot 311 and the second toggle slot 312 have one side capable of being in stop fit with the toggle member 6, and the other side capable of being in inclined fit with the toggle member 6. In this embodiment, the first toggle slot 311 and the second toggle slot 312 have a side surface configured as the stop surfaces 3111 and 3121, and at least one side surface of the first toggle slot 311 and the second toggle slot 312 is configured as the inclined surfaces 3112 and 3122; when the toggle member 6 extends into the first toggle slot 311 or the second toggle slot 312 toward one side of the gear 3 and abuts against the stop surfaces 3111 and 3121, the gear 3 is driven to rotate together by the toggle member 6 when the pedal 2 rotates upward, and the inclined surfaces 3112 and 3122 of the first toggle slot 311 or the second toggle slot 312 drive the toggle member 6 to move toward the pedal 2 when the pedal 2 rotates downward.

In this embodiment, when the pedal 2 is located at the first angular position and cannot rotate downward, one side of the toggle member 6 extends into the second toggle slot 312 and abuts against the stop surface of the second toggle slot 312; when the pedal 2 is located at the second angular position, one side of the striking member 6 extends into the first striking groove 311 and abuts against the stop surface 3111 of the first striking groove 311.

The shifting piece 6 is provided with a shifting portion 61 (as shown in fig. 9) on a side facing the sitting portion 1, and when the shifting portion 61 is opposite to the first shifting groove 311 or the second shifting groove 312, the shifting portion 61 may extend into the first shifting groove 311 or the second shifting groove 312 under the action of the second elastic piece 7. Preferably, one side surface of the striking part 61 is also provided with a bevel 62 that can be matched with the bevels 3112 and 3122 of the first striking groove 311 and the second striking groove 312, so that when the pedal 2 rotates downwards, the striking member 6 moves more smoothly.

In this embodiment, the toggle member 6 includes a body 63 and a blocking portion 64 extending upward from the body 63, the second elastic member 7 is configured as a compression spring, the compression spring is located between the bottom wall of the second mounting groove 22 and the blocking portion 64, and the toggle portion 61 is disposed on one side of the body 63. In other embodiments, the toggle portion 61 may be provided with only the body 63, and the spring is directly disposed between the body 63 and the bottom wall of the second mounting groove 22. The toggle portion 61 may be of other known and feasible construction.

In the present embodiment, the inclined surfaces 3112 and 3122 of the first and second dial grooves 311 and 312 each extend from the bottom of the stop surfaces 3111 and 3121 along the circumferential direction of the end surface of the gear 3.

As shown in fig. 8, in the same set of toggle grooves, the angle a between the stop surface 3111 of the first toggle groove 311 and the stop surface 3121 of the second toggle groove 312 is preferably equal to the angle by which the step 2 rotates downward from the third angular position to the first angular position. That is, assuming that the step 2 is rotated 30 degrees from the third angular position to the first angular position, the angle a between the stop surface 3111 of the first dial slot 311 and the stop surface 3112 of the second dial slot 312 is also 30 degrees. So set up, can guarantee that step 2 rotates from the second angular position to the third angular position and then down to the first angular position again when the piece 6 of stirring is relative with the second groove 312 of stirring of same group wave groove to stir 6 and move towards one side towards gear 3 under the effect of second elastic component 7, its portion 61 of stirring inserts in this second groove 312 of stirring and supports with the backstop face of second groove 312 of stirring.

The angle B between the stop surface 3121 of the second toggle groove 312 of one toggle groove of the two adjacent sets of toggle grooves and the stop surface 3111 of the first toggle groove 311 of the other adjacent set of toggle grooves is equal to the angle at which the step 2 rotates downward from the third angular position to the second angular position. That is, assuming that the pedal 2 is rotated 80 degrees from the third angular position to the second angular position after being rotated upward to the third angular position, the angle B is also 80 degrees. So set up, can guarantee that step 2 rotates from first angular position to the third angular position again when rotating down to the second angular position again, stir the portion 61 of stirring piece 6 and stir the first of groove 311 relatively, thus under the effect of second elastic component 7, stir piece 6 and move towards one side of gear 3, stir portion 61 inserts in this first and stir groove 311 and support with this first stop surface of stirring groove 311.

Because the toggle groove adopts the arrangement as above, when the pedal 2 can be guaranteed to move upwards from the first angle position/the second angle position to the third angle position and then rotate downwards, the pedal can precisely move to the preset second angle position/the first angle position in a rotating way, and the adjustment operation of the angle of the pedal 2 is more visual.

The specific set of toggle grooves and the angle A, B before each toggle groove stop surface may be set according to the angular difference of the first, second and third angular positions from each other.

Because the pedal 2 and the angle adjusting mechanism adopt the technical scheme, when the pedal 2 is to be adjusted from the first angle position (shown in fig. 1) to the second angle position (shown in fig. 2), the pedal 2 can be directly rotated upwards, the toggle piece 6 in the second toggle slot 312 of the toggle part 61 pushes the stop surface of the second toggle slot 312 to rotate together with the gear 3, and because the gear 3 cannot move left and right, the inclined surface of the first locking slot 321 of the gear pushes the locking piece 4 to move into the first mounting slot 12 by pushing the locking part 41 of the locking piece 4; when the step 2 is rotated up to the third angular position (as shown in fig. 12), the stopper projection 11 on the seat portion 1 abuts against the other end 202 of the step arc stopper groove 20, so that the step 2 can not be rotated up any more. At this time, the main body 40 of the locking member 4 has moved to a state completely separated from the first locking groove 321 and the arc-shaped limiting groove 20, and the locking portion 41 of the locking member 4 faces the second locking groove 322 in the same group of locking grooves, so that the locking member 4 moves towards the gear 3 under the action of the first elastic member 5 until the locking portion 41 of the locking member 4 is located in the second locking groove 322, and the locking portion 41 abuts against the stop surface of the second locking groove 322. Then the pedal 2 is rotated downwards to drive the toggle piece 6 to rotate together, because the toggle piece 6 contacts with the inclined surface of the second toggle groove 312 in the process of rotating downwards along with the pedal 2, the gear 3 cannot rotate downwards along with the pedal 2 and the toggle piece 6 but is kept still, and the locking part 41 abuts against the stop surface of the gear 3, which is the second locking groove 322, so that the gear 3 cannot rotate downwards along with the pedal 2; because the gear 3 does not rotate and does not move left and right, the poking piece 6 moves into the second mounting groove 22 under the action of the inclined surface of the second poking groove 312; when the pedal 2 rotates down to the second angular position with the toggle member 6, the limit bump 11 on the seat 1 abuts against one end of the arc limit groove 20 of the pedal 2, so that the pedal 2 can not rotate down any more, and in this state, the toggle member 6 is opposite to the first toggle groove 311 of the adjacent group of toggle grooves, so that under the action of the second elastic member 7, the toggle member 6 moves in the direction towards the gear 3 until the toggle portion 61 is inserted into the first toggle groove 311, and the toggle portion 61 contacts with the stop surface of the first toggle groove 311 (as shown in fig. 12). Thus, the step 2 is at the second angular position, and thus the adjustment and the switching of the step 2 from the first angular position to the second angular position are realized. Because in the second angular position the limit projection 11 abuts against one end of the arc-shaped limit groove 20, a gear is formed. Thus, when the lower leg of the child is leaned against the pedal 2, the pedal 2 does not rotate downwards, so that the use of the child is safer and more reliable when the pedal 2 is positioned at the second angle position.

In the process of rotating the step 2 downwards from the third angular position to the second angular position, the locking part 41 of the locking member 4 is kept in the second locking groove 322 and is in abutment with the stop surface of the second locking groove 322, that is, in the process, the gear 3 and the locking member 4 cannot rotate and move, and the relative position with the sitting part 1 is kept unchanged, so that the gear 3 and the locking member 4 are kept in the state when the second angular position is reached. This is the case, although the step 2 rotates to the first angular position during the downward rotation from the third angular position to the second angular position, because the locking member 4 is the locking portion 41 extending into the second locking groove 322, the locking member 4 does not have any engagement with the step 2, and the limit bump 11 does not abut against one end of the arc-shaped limit groove 20, so that the step 2 is not blocked from rotating downward in the first angular position, but can rotate downward to the second angular position until the limit bump 11 abuts against one end of the arc-shaped limit groove 20.

When the pedal 2 at the second angular position is to be adjusted to the first angular position, the pedal 2 is also rotated directly upwards, and the toggle piece 6 of the toggle part 61 in the first toggle slot 311 pushes the stop surface of the first toggle slot 311 to rotate together with the gear 3; because the gear 3 cannot move left and right, the locking piece 4 moves into the first mounting groove 12 under the pushing of the inclined surface of the second locking groove 322; when the step 2 is rotated up to the third angular position, the limit projection 11 on the seat 1 abuts against the other end 202 of the arc-shaped limit groove 20 of the step, so that the step 2 can not be rotated up any more, and at this time, the locking piece 4 has been moved to be completely out of the second locking groove 322 and opposite to the first locking groove 321 of the next adjacent set of locking grooves, and the first locking groove 321 communicates with the arc-shaped limit groove 20; so that under the action of the first elastic element 5, the locking element 4 moves towards the gear 3 until the side of the locking element main body 40 towards the gear 3 stretches into the first locking groove 321 and the arc-shaped limiting groove 20, the locking part 41 of the locking element 4 is also positioned in the first locking groove 321, the locking element 4 abuts against the stop surface of the first locking groove 321, and one end of the arc-shaped limiting groove 20 is further away from the locking element 4 by a certain distance; afterwards, the pedal 2 is rotated downwards again, and similarly, because the toggle piece 6 contacts with the inclined surface of the first toggle groove 311 in the process of rotating downwards along with the pedal 2, the gear 3 cannot rotate downwards along with the pedal 2 and the toggle piece 6, but is kept still, and the locking part 41 abuts against the stop surface of the gear 3, which is the first locking groove 321, and further, the gear 3 cannot rotate downwards along with the pedal 2 is ensured; under the action of the inclined surface of the first poking groove 311, the poking piece 6 moves into the first mounting groove 12; when the pedal 2 moves down to the first angle position, one end of the arc-shaped limit groove 20 abuts against the portion of the locking piece 4 extending into the arc-shaped limit groove 20, so that the pedal 2 cannot rotate down any more. In this state, the striking member 6 is completely separated from the first striking groove 311 and opposite to the second striking groove 312, and under the action of the second elastic member 7, the striking member 6 moves until the striking portion 61 thereof extends into the second striking groove 312 and abuts against the stop surface of the second striking member 6. At this time, the step 2 is at the first angular position relative to the seat portion 1 and cannot be rotated downward, so that the rotation of the step 2 is switched from the second angular position to the first angular position.

In the present embodiment, when the step 2 is in the first angular position, the step 2 is in a substantially parallel state with the seat portion 1 (as shown in fig. 1). When the pedal 2 is in the angle position, the lower leg of the child can extend forwards to rest on the pedal 2 when the child sits on the baby carriage; the seat back can be rotated backwards to a certain angle, so that the sitting portion 1 and the back can be used for the child to lie down for sleeping, and the pedal 2 approximately parallel to the sitting portion 1 corresponds to the length of the sleeping space of the child, and the lower leg of the child can be more comfortably stretched.

When the step 2 is in the second angular position, the step 2 is inclined downward relative to the seat 1 (as shown in fig. 2). When the step 2 is in this angular position, typically when a child is sitting on the stroller, the lower leg naturally rides down on the step 2.

In other embodiments, the first and second angular positions may be other suitable and feasible angular positions, as long as the lower leg of the child can be put on.

As described above, since the present utility model adopts the above structure, when the pedal 2 is to be adjusted from the first angular position to the second angular position, only the pedal 2 needs to be directly rotated upwards, the locking device can be unlocked through the gear, and then the pedal is rotated downwards to the second angular position, and no additional operation is required, so that the angle adjustment operation of the pedal is very simple; when the pedal is at the second angle position, the pedal is rotated up to a certain angle and then rotated down to the first angle position, so that the angle adjustment operation of the pedal is further simpler; when the pedal rotates upwards to the third angle position, the limit protruding block abuts against the other end of the arc limit groove, so that the pedal cannot rotate upwards any more, namely, when the pedal is required to be switched between the first angle position and the second angle position, the pedal is only required to rotate upwards until the pedal cannot rotate any more, and then the pedal is rotated downwards, so that the pedal angle adjustment operation of the child seat and the baby carriage is more visual and convenient.

In this embodiment, a pivot seat 10 (as shown in fig. 2) is disposed on the front side of the seat portion 1, the upper side of the pedal 2 is pivotally connected to the pivot seat 10, and the first mounting groove 12 and the limit bump 11 are disposed on a side of the pivot seat 10 facing the pedal 2.

In this embodiment, the sitting portion 1 is configured as a seat, the left and right sides of the front side of the seat are respectively provided with a pivot seat, and the step 2 is provided with left and right pivot seats respectively pivoted to the left and right sides of the seat.
