Description

Technical Field

[0001] The present invention relates to a children's product, in particular to a children's basket, a children's stroller and a children's car safety seat. Background Art

[0002] To meet the needs of both parents and children, child carriers are typically installed on strollers or child car seats when the child is relatively young. When installed on a stroller, the child carrier's handlebars can serve as a push handle for the user to push the stroller. The child carrier can also be carried independently, in which case the handlebars serve as a handle for the user to carry. Currently, some child carriers have handlebars that have both retractable and reversible functions. This requires the handlebars to have at least two locking mechanisms: one that controls the retraction of the handlebar to adjust its length, and one that controls the rotation of the handlebar (for switching the angle of the handlebar to facilitate pushing or carrying). These two locking mechanisms are configured to operate independently. However, when the child carrier needs to be switched between carrying and attaching to a stroller or child car seat, it is necessary to control both the first locking mechanism to adjust the length of the handlebar and the second locking mechanism to control the rotation of the handlebar, making operation very inconvenient. Summary of the Invention

[0003] The object of the present invention is to address the deficiencies in the prior art and to provide a child carrier, a child stroller and a child car safety seat with a handlebar that can be reversed and folded and easily locked and unlocked.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is:

[0005] A child carrier comprises a seat body, a retractable handlebar, wherein the handlebar comprises an upper handlebar, a lower handlebar, and a first locking mechanism;

[0006] The first locking mechanism has a locked working state and an unlocked working state. When the first locking mechanism is in the locked working state, the handlebar is locked in the extended working position or the retracted working position. When the first locking mechanism is in the unlocked working state, the handlebar switches between the extended working position and the retracted working position, and the upper handlebar slides relative to the lower handlebar to extend or retract the handlebar.

[0007] A rotation joint is provided between the lower end of the lower handlebar and the seat body, and the rotation joint includes a handlebar shaft, a second locking mechanism, and a safety mechanism;

[0008] The axis of the handlebar shaft extends along the left-right direction of the seat body, and the second locking mechanism and the safety mechanism both have a locked working state and an unlocked working state; when the safety mechanism is in the unlocked working state, the second locking mechanism is allowed to enter the unlocked working state from the locked working state, and at this time the lower end of the lower handlebar and the seat body can rotate around the handlebar shaft; when the safety mechanism is in the locked working state, the second locking mechanism is not allowed to enter the unlocked working state from the locked working state, and at this time the relative position between the lower end of the lower handlebar and the seat body is locked;

[0009] The handlebar has at least a pushing position and a carrying position relative to the seat body, and the handlebar is rotated to different angles relative to the seat body to correspond to the corresponding positions of the handlebar;

[0010] When the handlebar is in the pushing position, the first locking mechanism is in the unlocking working state and the upper handlebar slides downward relative to the lower handlebar to the retracted working position, the upper handlebar triggers the safety mechanism to change from the locking working state to the unlocking working state, allowing the second locking mechanism to change from the locking working state to the unlocking working state; during the process of the handlebar rotating about the handlebar shaft relative to the seat body, the first locking mechanism is in the locking working state, and the handlebar is also changed from the pushing position to the carrying position;

[0011] The first locking mechanism comprises:

[0012] a locking pin, the locking pin being located in the lower portion of the upper handlebar and slidably connected to the upper handlebar, the sliding direction of the locking pin being perpendicular to the sliding direction of the upper handlebar relative to the lower handlebar, the locking pin having a locking portion and a driving portion;

[0013] an upper handlebar locking hole, which is provided on a side wall of the upper handlebar adjacent to the locking portion;

[0014] a lower handlebar locking hole, which is provided on the lower side wall of the lower handlebar;

[0015] a sliding member, which is slidably disposed in the lower end portion of the upper handlebar along a sliding direction of the upper handlebar relative to the lower handlebar, and the lower end portion of the sliding member extends downwardly from the lower end portion of the upper handlebar;

[0016] a return spring disposed between the upper handlebar and the locking pin;

[0017] When the first locking mechanism is in the locked working state, the upper part of the sliding member blocks the moving path of the locking pin, and the locking part is inserted into the locking hole of the upper handlebar rod and the locking hole of the lower handlebar rod; when the first locking mechanism is in the unlocked working state, the upper part of the sliding member leaves the moving path of the locking pin, and the locking part disengages from the locking hole of the lower handlebar rod; the moving path of the locking pin refers to the sliding path of the locking pin when the first locking mechanism is switched from the locked working state to the unlocked working state; when the first locking mechanism is switched between the locked working state and the unlocked working state, the locking pin slides along the upper handlebar rod, and the return spring applies a force on the locking pin tending to switch to the locked working state.

[0018] Preferably, a first guide slope is provided on the side surface of the seat body, and the first guide slope is inclined relative to the sliding direction of the sliding member, and the first guide slope is parallel to the axis of the handlebar shaft; in the process of the handlebar being converted from the pushing gear to the basket carrying gear, the lower end of the sliding member is pressed against the first guide slope and slidably connected, and the first guide slope pushes the sliding member to slide upward, so that the upper part of the sliding member blocks the moving path of the locking pin, thereby keeping the locking part inserted in the locking hole of the lower handlebar.

[0019] Furthermore, a circumferential surface is provided on the seat body adjacent to the rotating joint side, the center of the circumferential surface is on the axis of the handlebar shaft, and the first guiding slope is a section on the circumferential surface.

[0020] Furthermore, when the handle rod is switched between the basket carrying position and other gears, the lower end of the sliding member is pressed against the circumferential surface and slidably connected, so that the upper part of the sliding member continuously blocks the moving path of the locking pin. The other gears do not include the pushing gear.

[0021] Preferably, a socket is provided on the locking pin, and when the first locking mechanism is in a locking working state, the upper portion of the sliding member is inserted into the socket; when the first locking mechanism is in an unlocking working state, the upper portion of the sliding member is disengaged from the socket.

[0022] Furthermore, a traction device is provided in the upper handlebar, and an unlocking guide block is connected to the traction device, and the unlocking guide block is at least partially inserted into the socket, and one side of the unlocking guide block is in contact with the inner wall of one side of the socket through a second guide slope, and the inner wall of one side of the socket constitutes the driving part, and the second guide slope is inclined relative to the sliding direction of the locking pin, and the second guide slope is provided on one side of the driving part or / and the unlocking guide block; when the first locking mechanism is in the locked working state, the upper part of the sliding member is located between the inner wall of the other side of the socket and the other side of the unlocking guide block; when the upper part of the sliding member is separated from the socket, the traction device pulls the unlocking guide block, and the second guide slope pushes the driving part to slide in the direction away from the locking hole of the lower handlebar, so that the first locking mechanism is in the unlocking working state.

[0023] Preferably, the second locking mechanism comprises:

[0024] A first connecting member, wherein the first connecting member is fixedly arranged on the seat body;

[0025] a second coupling member, the second coupling member being fixedly disposed on the lower end portion of the lower handlebar;

[0026] a locking member, the locking member being disposed between the first combining member and the second combining member;

[0027] an elastic member, the elastic member abutting against the locking member, the elastic member being used to drive the locking member to slide along the axis of the handlebar shaft, so that the locking member has a tendency to be locked in position with the first coupling member and the second coupling member at the same time;

[0028] When the second locking mechanism is in a locked state, the locking member is locked relative to the first and second combining members respectively; when the second locking mechanism is in an unlocked state, the locking member is locked relative to only one of the first and second combining members and is disengaged from the other combining member; when the locking member moves, the second locking mechanism switches between the locked state and the unlocked state;

[0029] The safety mechanism is used to lock the movement of the locking member in a locking working state, and allows the movement of the locking member in an unlocking working state.

[0030] Furthermore, the first coupling member is provided with a radially concave first groove, and the first groove extends along the axis of the handlebar shaft;

[0031] The second coupling member is provided with a radially concave second groove, and the second groove extends along the axis of the handlebar shaft;

[0032] The locking member is connected to an operating button exposed at the rotating joint, and the locking member is axially slidably arranged along the axis of the handlebar shaft. The locking member is provided with a radially protruding rack extending along the axis of the handlebar shaft.

[0033] When the second locking mechanism is in a locked state, the rack is inserted into the first groove and the second groove respectively, so that the locking member is engaged with the first and second combining members at the same time; when the second locking mechanism is in an unlocked state, the rack is disengaged from the groove on one of the components and is only inserted into the groove on the other component, so that the locking member is engaged with only one of the first and second combining members; when the operating button is pressed to drive the locking member to slide axially, the second locking mechanism switches between the locked state and the unlocked state;

[0034] The safety mechanism is a blocking piece. When the safety mechanism is in the locked working state and the second locking mechanism is also in the locked working state, the blocking piece blocks the moving path of the locking member; when the safety mechanism is in the unlocked working state, the blocking piece leaves the moving path of the locking member; the moving path of the locking member refers to the sliding path of the locking member when the second locking mechanism switches from the locked working state to the unlocked working state.

[0035] Furthermore, when the upper handlebar slides downward relative to the lower handlebar to a retracted working position, the upper handlebar pushes the blocking piece to leave the moving path of the locking member.

[0036] Preferably, the handlebar further has a safety seat gear relative to the seat body.

[0037] A baby stroller comprises a frame body and wheels arranged below the frame body. The frame body is provided with the above-mentioned child carrier.

[0038] A child car safety seat comprises a frame body, wheels arranged below the frame body, and a base. The frame body has an unfolded use state and a folded use state. When the frame body is in the folded use state, the frame body is mounted on the base, and the frame body is provided with the above-mentioned child carrier.

[0039] A child car safety seat comprises a base and a child carrier arranged on the base.

[0040] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0041] The child carrier of the present invention has a handlebar having a pushing gear and a carrying gear and can be switched between the two gears. The length of the handlebar can also be adjusted. When the upper handlebar slides relative to the lower handlebar to a retracted state and the handlebar rotates, the first locking mechanism can be automatically locked, so that the upper and lower handlebars cannot slide relative to each other. This saves the trouble of controlling the unlocking of both the first locking mechanism and the second locking mechanism when shifting gears, and the child carrier is more convenient to use.

[0066] like Figures 1 to 17 As shown, the child carrier 1 of the present invention comprises a seat body 2 and a retractable handlebar 3 , and the handlebar 3 is rotatably arranged on the seat body 2 .

[0067] The handlebar 3 includes an upper handlebar 4, a lower handlebar 5 and a first locking mechanism 6. Figure 5 、 Figure 9 、 Figure 11 and Figure 13 As shown, the upper handlebar 4 can be slidably arranged on the lower handlebar 5 along the length extension direction of the lower handlebar 5, and the handlebar 3 is rotationally connected to the seat body 2 through a rotation joint 7.

[0068] In this embodiment, Figure 2 As shown, the lower handlebar rod 5 has a lumen extending along its length direction, and the upper handlebar rod 4 is partially inserted into the lumen and can be slidably arranged along the length extension direction of the lumen.

[0069] The handlebar 3 and the seat body 2 rotate through the rotating joint 7 to have at least a pushing gear and a carrying gear. The handlebar 3 is rotated to different angles relative to the seat body 2 to switch to the corresponding gear of the handlebar 3.

[0070] When the handlebar 3 is in the pushing gear position, the handlebar 3 is tilted and extended, and the handlebar 3 can be in an extended state, such as Figure 1 、 Figure 14 and Figure 15 As shown, it can also be in a contracted state, such as Figure 4 As shown, the child carrier 1 can be switched between an extended working position and a retracted working position. In this case, the child carrier 1 is mounted on the frame body 34 of the child stroller and serves as the seat of the child stroller. The handlebar 3 can be used to push the child stroller (i.e., serves as a push handle for the child stroller). The length of the handlebar 3 can be adjusted according to the pusher's requirements.

[0071] The pushing gear includes a forward pushing gear and a reverse pushing gear. When the handlebar 3 is in the forward pushing gear position, the handlebar 3 extends from the back to the front and upwards. Figure 1 、 Figure 4 and Figure 14 When the handlebar 3 is in the reverse push gear position, the handlebar 3 extends upward from the front to the rear, as shown Figure 15 shown.

[0072] When the handle bar 3 is in the basket gear position, the handle bar 3 is extended in the vertical direction or tilted, and the handle bar 3 is in the retracted working position and cannot be converted to the extended working position. At this time, the handle bar 3 is mainly used to carry the child basket 1, and the child basket 1 can be carried alone, such as Figure 8 shown.

[0073] The handle bar 3 also has an anti-tilt gear, which is located between the basket carrying gear and the pushing gear. Figure 10 As shown, when the handlebar 3 is in the anti-tilt position, the handlebar 3 is fixed relative to the seat body 2 to prevent the child carrier from tipping over when being carried.

[0074] The handlebar 3 also has a safety seat gear, such as Figure 12 As shown, when the handlebar 3 is in the safety seat gear position, the handlebar 3 is in the retracted working position and cannot be converted to the extended working position.

[0075] The child carrier 1 also includes a first locking mechanism 6, which has a locked state and an unlocked state. When the first locking mechanism 6 is in the locked state, the handlebar 3 is locked in the extended or retracted position. When the first locking mechanism 6 is in the unlocked state, the handlebar 3 switches between the extended and retracted positions, and the upper handlebar 4 slides relative to the lower handlebar 5, causing the handlebar 3 to extend or retract. As the upper handlebar 4 extends, the length of the handlebar 3 increases as it extends beyond the lumen of the lower handlebar 5. When the upper handlebar 4 reaches its maximum extension from the lower handlebar 5, the handlebar 3 is at its maximum length.

[0076] Combine Figure 5 、 Figure 9 and Figure 11 As shown, the first locking mechanism 6 includes a locking pin 12, which is located in the lower portion of the upper handlebar 4 and is slidably connected to the upper handlebar 4. The sliding direction of the locking pin 12 is perpendicular to the sliding direction of the upper handlebar 4 relative to the lower handlebar 5. The locking pin 12 has a locking portion 13 and a driving portion 14; an upper handlebar locking hole 15, which is defined in the side wall of the upper handlebar 4 adjacent to the locking portion 13; and a lower handlebar locking hole 16, which is defined in the lower side wall of the lower handlebar 5.

[0077] The sliding member 17 is slidably arranged in the lower end portion of the upper handlebar rod 4 along the sliding direction of the upper handlebar rod 4 relative to the lower handlebar rod 5, and the lower end portion of the sliding member 17 extends downward from the lower end portion of the upper handlebar rod 4; the return spring 18 is arranged between the upper handlebar rod 4 and the locking pin 12.

[0078] When the first locking mechanism 6 is in the locked working state, the upper part of the sliding member 17 blocks the moving path of the locking pin 12, and the locking part 13 is inserted into the upper handlebar rod locking hole 15 and the lower handlebar rod locking hole 16; when the first locking mechanism 6 is in the unlocked working state, the upper part of the sliding member 17 leaves the moving path of the locking pin 12, and the locking part 13 disengages from the lower handlebar rod locking hole 16; the moving path of the locking pin 12 refers to the sliding path of the locking pin 12 when the first locking mechanism 6 is switched from the locked working state to the unlocked working state; when the first locking mechanism 6 is switched between the locked working state and the unlocked working state, the locking pin 12 slides along the upper handlebar rod 4, and the return spring 18 applies a force on the locking pin 12 tending to switch to the locked working state.

[0079] A first guide slope 19 is provided on the side of the seat body 2. Figure 5 、 Figure 9 、 Figure 11 and Figure 13 As shown, the first guide bevel 19 is inclined relative to the sliding direction of the slider 17, and the first guide bevel 19 is parallel to the axis 11 of the handlebar shaft; when the handlebar 3 is switched from the pushing gear to the basket carrying gear, the lower end of the slider 17 is pressed against the first guide bevel 19 and is slidably connected, and the first guide bevel 19 pushes the slider 17 to slide upward, so that the upper part of the slider 17 blocks the moving path of the locking pin 12, thereby keeping the locking portion 13 inserted into the locking hole 16 of the lower handlebar.

[0080] A circumferential surface 20 is provided on the seat body 2 adjacent to the rotary joint 7 . The center of the circumferential surface 20 is on the axis 11 of the handlebar shaft. The first guiding inclined surface 19 is a section on the circumferential surface 20 .

[0081] When the handlebar 3 switches between the basket carrying position and other positions, the lower end of the slider 17 presses against the circumferential surface 20 and is slidably connected, so that the upper part of the slider 17 continuously blocks the moving path of the locking pin 12. Other positions do not include the pushing position.

[0082] The locking pin has an insertion hole 21 . When the first locking mechanism 6 is in the locking state, the upper portion of the sliding member 17 is inserted into the insertion hole 21 . When the first locking mechanism 6 is in the unlocking state, the upper portion of the sliding member 17 is disengaged from the insertion hole 21 . A traction device 22 is provided in the upper handlebar 4, and an unlocking guide block 23 is connected to the traction device 22. The unlocking guide block 23 is at least partially inserted into the socket 21, and one side of the unlocking guide block 23 contacts the inner wall of one side of the socket 21 through a second guide bevel 24. The inner wall of one side of the socket 21 constitutes the driving part 14, and the second guide bevel 24 is inclined relative to the sliding direction of the locking pin 12. The second guide bevel 24 is provided on the driving part 14. In some other embodiments, the second guide bevel 24 is provided on one side of the unlocking guide block 23; when the first locking mechanism 6 is in the locked working state, the upper part of the sliding member 17 is located between the inner wall of the other side of the socket 21 and the other side of the unlocking guide block 23; when the upper part of the sliding member 17 is separated from the socket 21, the traction device 22 pulls the unlocking guide block 23, and the second guide bevel 24 pushes the driving part 14 to slide in the direction away from the locking hole 16 of the lower handlebar, so that the first locking mechanism 6 is in the unlocked working state.

[0083] The rotating joint 7 includes a handlebar shaft 8, a second locking mechanism 9 and a safety mechanism 10. The axis 11 of the handlebar shaft 8 extends along the left and right directions of the seat body 2. The second locking mechanism 9 and the safety mechanism 10 both have a locked working state and an unlocked working state; when the safety mechanism 10 is in the unlocked working state, the second locking mechanism 9 is allowed to enter the unlocked working state from the locked working state, and at this time the lower end of the lower handlebar 5 and the seat body 2 can rotate around the handlebar shaft 8; when the safety mechanism 10 is in the locked working state, the second locking mechanism 9 is not allowed to enter the unlocked working state from the locked working state, and at this time the relative position between the lower end of the lower handlebar 5 and the seat body 2 is locked.

[0084] The second locking mechanism 9 includes a first coupling member 25, which is fixedly arranged on the seat body 2; a second coupling member 26, which is fixedly arranged at the lower end of the lower handlebar rod 5; a locking member 27, which is arranged between the first coupling member 25 and the second coupling member 26; an elastic member 28, which is against the locking member 27, and the elastic member 28 is used to drive the locking member 27 to slide along the axis 11 of the handlebar shaft, so that the locking member 27 has a tendency to be locked in position with the first coupling member 25 and the second coupling member 26 at the same time.

[0085] When the second locking mechanism 9 is in the locked working state, the locking member 27 is locked relative to the first combining member 25 and the second combining member 26 respectively. When the second locking mechanism 9 is in the unlocked working state, the locking member 27 is locked relative to only one of the first combining member 25 and the second combining member 26, and is disengaged from the other combining member; when the locking member 27 moves, the second locking mechanism 9 switches between the locked working state and the unlocked working state.

[0086] The first coupling member 25 is provided with a radially concave first groove 29 extending along the axis 11 of the handlebar shaft. The second coupling member 26 is provided with a radially concave second groove 30 extending along the axis 11 of the handlebar shaft.

[0087] The locking member 27 is connected to an operating button 31 exposed at the rotating joint. The locking member 27 is axially slidably arranged along the axis 11 of the handlebar shaft. The locking member 27 is provided with a radially protruding rack 32, which extends along the axis 11 of the handlebar shaft.

[0088] When the second locking mechanism 9 is in the locking working state, the rack 32 is respectively inserted into the first groove 29 and the second groove 30, so that the locking member 27 is engaged with the first combining member 25 and the second combining member 26 at the same time; when the second locking mechanism 9 is in the unlocking working state, the rack 32 is disengaged from the groove on one of the components and only inserted into the groove on the other component, so that the locking member 27 is engaged with only one of the first combining member 25 and the second combining member 26; when the operation button 31 is pressed to drive the locking member 27 to slide axially, the second locking mechanism 9 switches between the locking working state and the unlocking working state.

[0089] The safety mechanism 10 is used to lock the movement of the locking member 27 in the locked state and to allow movement of the locking member 27 in the unlocked state. The safety mechanism 10 comprises a blocking plate 33. When the safety mechanism 10 is in the locked state and the second locking mechanism 9 is also in the locked state, the blocking plate 33 blocks the movement path of the locking member 27. When the safety mechanism 10 is in the unlocked state, the blocking plate 33 leaves the movement path of the locking member 27. The movement path of the locking member 27 refers to the sliding path of the locking member 27 when the second locking mechanism 9 transitions from the locked state to the unlocked state. When the upper handlebar 4 slides downward relative to the lower handlebar 5 to the retracted position, the upper handlebar 4 pushes the blocking plate 33 out of the movement path of the locking member 27.

[0090] When the handlebar 3 is in the pushing gear position, the first locking mechanism 6 is in the unlocking working state and the upper handlebar 4 slides downward relative to the lower handlebar 5 to the retracted working position. Figure 4 As shown, the upper handlebar 4 triggers the safety mechanism 10 to change from the locked working state to the unlocked working state, allowing the second locking mechanism 9 to change from the locked working state to the unlocked working state.
