Description

Technical Field

[0001] The present invention relates to the technical field of baby strollers, and particularly relates to a baby stroller and its telescopic handle assembly. Background Art

[0002] Baby strollers mainly include a bracket and a seat component. The seat component is assembled on the bracket. The bracket mainly includes a front-wheel bracket, a rear-wheel bracket, and a handle bracket. Corresponding front wheels and rear wheels are provided on the front-wheel bracket and the rear-wheel bracket. Among them, the length of the handle bracket is adjustable and is fixed at different length positions through a fixing mechanism. The fixing mechanism mainly includes the cooperation of a locking pin and a positioning hole; the front-wheel bracket and the rear-wheel bracket can be folded and are kept in an open state through a locking mechanism. The locking mechanism mainly includes a clutch.

[0003] To achieve the function of adjusting the length of the handle bracket and the folding function of the front-wheel bracket and the rear-wheel bracket, an actuating mechanism is provided on the handle bracket. The actuating mechanism is linked to the fixing mechanism to release the fixation to achieve the adjustment of the length of the handle bracket, or the actuating mechanism is linked to the locking mechanism to release the locking to achieve the folding of the front-wheel bracket and the rear-wheel bracket.

[0004] In the prior art, the function of adjusting the length of the handle bracket and the folding function of the front-wheel bracket and the rear-wheel bracket are respectively achieved by a single actuating mechanism linked to the fixing mechanism and the locking mechanism, or the function of adjusting the length of the handle bracket and the folding function of the front-wheel bracket and the rear-wheel bracket are correspondingly achieved by two groups of actuating mechanisms linked to the fixing mechanism and the locking mechanism one by one; however, when attempting to achieve one of the functions, it may trigger the implementation of the other function, and the triggered other function may be dangerous. For example, when the baby stroller is in use and attempting to achieve the function of adjusting the length of the handle bracket, it may accidentally trigger the folding function of the front-wheel bracket and the rear-wheel bracket, and this function is dangerous when the baby stroller is in use. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems in the above technologies to some extent. For this reason, an object of the present invention is to provide a telescopic handle assembly for a baby stroller, so as to effectively avoid accidentally triggering the implementation of the other function when achieving one of the functions of adjusting the length of the handle bracket and the folding function of the front-wheel bracket and the rear-wheel bracket, thereby avoiding usage risks.

[0006] The second object of the present invention is to provide a baby stroller.

[0007] To achieve the above object, an embodiment of the first aspect of the present invention provides a telescopic handle assembly for a baby stroller, including:

[0008] A fixed sleeve, wherein a plurality of positioning holes are axially provided on the fixed sleeve;

[0009] A telescopic sleeve, wherein the telescopic sleeve is slidably sleeved with the fixed sleeve;

[0010] A sliding body, the sliding body being fixed in the telescopic sleeve, and a first locking piece being radially slidably arranged on the sliding body and being adapted to extend out of the telescopic sleeve and cooperate with the positioning hole;

[0011] a first sliding member, on which a second locking member connected to a locking mechanism for keeping the bracket in an open state is radially slidably disposed, and the first sliding member is configured such that when the first sliding member is slid, the second locking member drives the locking mechanism to unlock;

[0012] The second sliding member is configured to link the first locking member to disengage from the positioning hole and drive the second locking member to disconnect from the locking mechanism when the second sliding member is slid.

[0013] According to an embodiment of the present invention, a telescopic handle assembly of a baby stroller is configured such that when the second sliding member is slid, the first locking member is linked to disengage from the positioning hole and the second locking member is driven to disconnect from the locking mechanism that keeps the bracket in an open state, that is, when the first locking member is disengaged from the positioning hole to achieve the handle bracket length adjustment function, the second locking member is disconnected from the locking mechanism that keeps the bracket in an open state and the front wheel bracket and rear wheel bracket folding function cannot be achieved; at the same time, when the first sliding member is slid, the second locking member drives the locking mechanism to unlock and achieve the front wheel bracket and rear wheel bracket folding function. At this time, the first locking member cooperates with the positioning hole and the handle bracket length adjustment function cannot be achieved. Therefore, the handle bracket length adjustment function and the front wheel bracket and rear wheel bracket folding function are selected to be achieved. When one of the handle bracket length adjustment function and the front wheel bracket and rear wheel bracket folding function is achieved, it is effectively avoided that the other function is achieved by mistaken triggering, thereby avoiding danger in use.

[0014] In addition, the telescopic handle assembly of a baby stroller according to the above embodiment of the present invention may also have the following additional technical features:

[0015] Optionally, the first sliding member is axially slidably disposed on the sliding body and connected to a first pull wire; the second sliding member is axially slidably disposed on the sliding body and connected to a second pull wire.

[0016] Specifically, a first elastic reset member is provided between the first sliding member and the sliding body; a second elastic reset member is provided between the second sliding member and the sliding body, and the second sliding member is provided with a first oblique groove suitable for cooperating with the first locking member to drive the first locking member to extend and retract, and a second oblique groove and a yielding straight groove suitable for cooperating with the second locking member and being connected to each other, the second oblique groove is suitable for driving the second locking member to radially extend and retract, and the yielding straight groove is suitable for driving the second locking member to axially translate.

[0017] Furthermore, a return spring is provided between the second locking member and the first sliding member.

[0018] Further, in the initial state, the elastic restoring force of the first elastic restoring member is greater than the elastic restoring force of the second elastic restoring member, and the elastic restoring force of the second elastic restoring member is greater than the elastic restoring force of the restoring spring. The elastic restoring force of the maximum compression amount of the restoring spring is less than the elastic restoring force of the second elastic restoring member in the initial state. The elastic restoring force of the maximum compression amount of the second elastic restoring member is less than the elastic restoring force of the first elastic restoring member in the initial state.

[0019] Further, the second sliding member is configured such that when the second sliding member is slid, the first inclined groove drives the first locking member to disengage from the positioning hole, and the second inclined groove drives the second locking member to disconnect from the locking mechanism.

[0020] Further, the first sliding member is configured such that when the first sliding member is slid, the straight displacement groove is suitable for driving the second locking member to translate axially to drive the locking mechanism to unlock.

[0021] Furthermore, the first locking member includes a first locking body and a first boss radially arranged on the first locking body, the first locking body is slidably arranged on the sliding body, and the first boss cooperates with the first inclined groove.

[0022] Furthermore, the second locking member includes a second locking body and a second boss radially arranged on the second locking body, the second locking body is slidably arranged on the first sliding member, and the second boss cooperates with the second inclined groove and the yielding straight groove.

[0023] To achieve the above-mentioned object, a second embodiment of the present invention provides a baby stroller, comprising the above-mentioned telescopic handle assembly.

[0024] A baby stroller according to an embodiment of the present invention includes a telescopic handle assembly. Since the second slider is arranged such that when the second slider is slid, the first locking member is linked to disengage from the positioning hole and at the same time the second locking member is driven to disconnect from the locking mechanism that keeps the bracket in the open state. That is, when the first locking member disengages from the positioning hole to realize the function of adjusting the length of the handle bracket, the second locking member disconnects from the locking mechanism that keeps the bracket in the open state and the folding function of the front wheel bracket and the rear wheel bracket cannot be realized. At the same time, when the first slider is slid, the second locking member drives the locking mechanism to unlock, realizing the folding function of the front wheel bracket and the rear wheel bracket. At this time, the first locking member cooperates with the positioning hole and the function of adjusting the length of the handle bracket cannot be realized. Therefore, either the function of adjusting the length of the handle bracket or the folding function of the front wheel bracket and the rear wheel bracket is realized. When one of the functions of adjusting the length of the handle bracket and the folding function of the front wheel bracket and the rear wheel bracket is realized, it is effectively avoided that the other function is accidentally triggered, thus avoiding the use of danger.

Detailed implementation mode

[0036] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0037] In the present invention, when the second sliding member is set to slide the second sliding member, the first locking member is linked to disengage from the positioning hole, and at the same time, the second locking member is driven to disconnect from the locking mechanism that keeps the bracket in the open state. That is, when the first locking member disengages from the positioning hole to realize the function of adjusting the length of the handle bracket, the second locking member disconnects from the locking mechanism that keeps the bracket in the open state and cannot realize the folding function of the front wheel bracket and the rear wheel bracket; at the same time, when the first sliding member is slid, the second locking member drives the locking mechanism to unlock, realizing the folding function of the front wheel bracket and the rear wheel bracket. At this time, the first locking member cooperates with the positioning hole and cannot realize the function of adjusting the length of the handle bracket. Therefore, either the function of adjusting the length of the handle bracket or the folding function of the front wheel bracket and the rear wheel bracket is realized. When one of the functions of adjusting the length of the handle bracket and the folding function of the front wheel bracket and the rear wheel bracket is realized, it effectively avoids mis-triggering and realizes the other function, thereby avoiding danger in use.

[0038] In order to better understand the above technical solution, the exemplary embodiments of the present invention will be described in more detail below with reference to the drawings. Although the exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0039] In order to better understand the above technical solution, the above technical solution will be described in detail below in combination with the specification drawings and specific implementation modes.

[0040] As Figures 1 to 9 shown, a telescopic handle assembly of a baby stroller according to an embodiment of the present invention includes a fixed sleeve 1, a telescopic sleeve 2, a sliding body 3, a first sliding member 4 and a second sliding member 5.

[0041] The fixed sleeve 1 is axially provided with a plurality of positioning holes 11. The axial direction is defined as the length direction of the fixed sleeve 1, and the radial direction is defined as the width direction. A connecting member of a locking mechanism for keeping the bracket in an open state is provided in the fixed sleeve 1.

[0042] The telescopic sleeve 2 is slidably sleeved on the fixed sleeve 1. In this embodiment, the telescopic sleeve 2 is slidably sleeved in the fixed sleeve 1, and the sliding limit of the telescopic sleeve 2 is restricted by a stopper.

[0043] The sliding body 3 is fixed in the telescopic sleeve 2. The sliding body 3 can be fixed in the telescopic sleeve 2 by sequentially passing a limit pin through the telescopic sleeve 2 and the sliding body 3. A first locking member 6 adapted to extend out of the telescopic sleeve 2 and cooperate with the positioning hole 11 is slidably provided on the sliding body 3 in the radial direction. A relief hole can be provided on the telescopic sleeve 2, and the first locking member 6 extends out of the telescopic sleeve 2 through the relief hole.

[0044] A second locking member 7 connected to the locking mechanism for keeping the bracket in an open state is slidably provided on the first sliding member 4 in the radial direction. The first sliding member 4 is arranged such that when the first sliding member 4 is slid, the second locking member 7 drives the locking mechanism to unlock. In the initial state, as Figure 3 shown, the connecting member of the locking mechanism for keeping the bracket in an open state is provided with a groove, and the second locking member 7 is snapped into the groove to be connected to the locking mechanism.

[0045] The second sliding member 5 is arranged such that when the second sliding member 5 is slid, the first locking member 6 is linked to disengage from the positioning hole 11 and at the same time the second locking member 7 is driven to disconnect from the locking mechanism.

[0046] Since the second sliding member 5 is arranged such that when the second sliding member 5 is slid, the first locking member 6 is linked to disengage from the positioning hole 11 and at the same time the second locking member 7 is driven to disconnect from the locking mechanism, that is, when the first locking member 6 disengages from the positioning hole 11 to realize the function of adjusting the length of the handle bracket, the second locking member 7 disconnects from the locking mechanism for keeping the bracket in an open state and the folding function of the front wheel bracket and the rear wheel bracket cannot be realized; at the same time, when the first sliding member 4 is slid, the second locking member 7 drives the locking mechanism to unlock, and the folding function of the front wheel bracket and the rear wheel bracket is realized. At this time, the first locking member 6 cooperates with the positioning hole 11, and the function of adjusting the length of the handle bracket cannot be realized. Therefore, either the function of adjusting the length of the handle bracket or the folding function of the front wheel bracket and the rear wheel bracket is realized. When one of the functions of adjusting the length of the handle bracket and the folding function of the front wheel bracket and the rear wheel bracket is realized, it is effectively avoided that the other function is accidentally triggered, thereby avoiding danger in use.

[0047] Optionally, the first slider 4 is axially slidably disposed on the sliding body 3. The first slider 4 is connected to a first wire 41, and the first wire 41 is connected to an actuating mechanism. The actuating mechanism can pull the first wire 41 to move, thereby driving the first slider 4 to slide. The second slider 5 is axially slidably disposed on the sliding body 3. The second slider 5 is connected to a second wire 51, and the second wire 51 is connected to the actuating mechanism. The actuating mechanism can pull the second wire 51 to move, thereby driving the second slider 5 to slide. The first slider 4 and the second slider 5 are arranged side by side and slidably.

[0048] A first elastic reset member 81 is provided between the first slider 4 and the sliding body 3; a second elastic reset member 82 is provided between the second slider 5 and the sliding body 3. The second slider 5 is provided with a first inclined groove 52 adapted to cooperate with the first locking member 6 to drive the first locking member 6 to expand and contract, and a second inclined groove 53 and a relief straight groove 54 adapted to cooperate with the second locking member 7 and communicate with each other. The second inclined groove 53 is adapted to drive the second locking member 7 to radially expand and contract, and the relief straight groove 54 is adapted to drive the second locking member 7 to axially translate. Optionally, a return spring 9 is provided between the second locking member 7 and the first slider 4 to drive the second locking member 7 to reset.

[0049] In the initial state, that is, when neither the first slider 4 nor the second slider 5 is slid, the elastic reset force of the first elastic reset member 81 is greater than the elastic reset force of the second elastic reset member 82, and the elastic reset force of the second elastic reset member 82 is greater than the elastic reset force of the return spring 9. The elastic reset force of the return spring 9 at the maximum compression amount is less than the elastic reset force of the second elastic reset member 82 in the initial state. The elastic reset force of the second elastic reset member 82 at the maximum compression amount is less than the elastic reset force of the first elastic reset member 81 in the initial state.

[0050] The second slider 5 is configured such that when the second slider 5 is slid, the first inclined groove 52 drives the first locking member 6 to disengage from the positioning hole 11, and at the same time, the second inclined groove 54 drives the second locking member 7 to disconnect from the locking mechanism. As Figure 3 and Figure 4 shown, when the first locking member 6 cooperates with the positioning hole 11 and at the same time the second locking member 7 cooperates with the locking mechanism, at this time, the first locking member 6 is at the lowest position, that is, closest to the locking mechanism. When the actuating mechanism pulls the second wire 51 to move, it drives the second slider 5 to slide. The first inclined groove 52 drives the first locking member 6 to move radially inward, disengaging from the cooperation with the positioning hole 11. At the same time, the second inclined groove 53 drives the second locking member 7 to move radially inward, disengaging from the cooperation with the locking mechanism. At this time, when the handle bracket length adjustment function is realized, the folding function of the front wheel bracket and the rear wheel bracket cannot be realized.

[0051] As Figure 5As shown, the first locking member 6 is disengaged from the positioning hole 11, and at the same time, the second locking member 7 is disengaged from the locking mechanism, the second pull line 51 is released, and the second sliding member 5, under the action of the second elastic reset member 82, the first inclined groove 52 of the second sliding member 5 drives the first locking member 6 to move radially outward to cooperate with the positioning hole 11; at the same time, the first sliding member 4 is reset under the action of the first elastic reset member 81, and the second locking member 7 is reset under the action of the reset spring 9. At this time, the first locking member 6 cooperates with the positioning hole 11 farther away from the locking mechanism, that is, the first locking member 6 cooperates with the positioning hole 11 at a higher position.

[0052] like Figure 6 As shown, when the first locking member 6 is at a high position, the actuating mechanism continues to pull the second pull line 51 to move, driving the second sliding member 5 to slide, and the first inclined groove 52 drives the first locking member 6 to move radially inward, disengaging from the positioning hole 11; the second inclined groove 53 of the second sliding member 5 drives the second locking member 7 to move radially inward, at this time, the second locking member 7 is not connected to the locking mechanism, and the folding function of the front wheel bracket and the rear wheel bracket cannot be realized. At this time, the retractable handle can be moved to a lower position or a higher position.

[0053] The first sliding member 4 is configured to allow the straight groove 54 to drive the second locking member 7 to translate axially and unlock the locking mechanism when the first sliding member 4 is slid. Figure 7 As shown, when the retractable handle is at the lowest position, that is, the first locking member 6 is closest to the locking mechanism, the actuating mechanism continues to pull the first pull wire 41 to move, thereby driving the first sliding member 4 to slide, and the first sliding member 4 drives the second locking member 7 to move in the yielding straight groove 54, and the second locking member 7 is embedded in the groove of the locking mechanism connecting member, thereby driving the locking mechanism to move and unlock, thereby realizing the folding function of the front wheel bracket and the rear wheel bracket, that is, realizing the vehicle folding function.

[0054] like Figure 8 As shown, when the retractable handle is at a high position, that is, the first locking member 6 is further away from the locking mechanism position, the actuating mechanism continues to pull the first pull wire 41 to move, thereby driving the first sliding member 4 to slide, and the first sliding member 4 drives the second locking member 7 to move in the yielding straight groove 54. Since the second locking member 7 is not in the groove of the locking mechanism connecting member, the locking mechanism cannot be driven to move and unlock, that is, the vehicle folding function cannot be realized.

[0055] The first locking member 6 includes a first locking body 61 and a first boss 62 radially arranged on the first locking body 61. The first locking body 61 is slidably arranged on the sliding body 3, and the first boss 62 cooperates with the first inclined groove 52. When the second sliding member 5 slides, the first inclined groove 52 pushes the first boss 62 to drive the first locking body 61 to move radially inward and outward.

[0056] The second locking member 7 includes a second locking body 71 and a second boss 72 radially arranged on the second locking body 71. The second locking body 71 is slidably arranged on the first sliding member 4, and the second boss 72 cooperates with the second inclined groove 53 and the straight groove 54. When the second sliding member 5 slides, the second inclined groove 53 pushes the second boss 72 to move radially inward and outward, and when the first sliding member 4 slides, the second boss 72 slides in the straight groove 54. A convex ridge that cooperates with the groove of the locking mechanism connecting member can be arranged on the upper end of the second locking body 71.

[0057] like Figures 1 to 9 As shown, a baby stroller according to an embodiment of the present invention includes a front wheel bracket, a rear wheel bracket and a handle bracket, and also includes the telescopic handle assembly. The front wheel bracket and the rear wheel bracket are provided with front wheels and rear wheels respectively, wherein the handle bracket can be adjusted in length and fixed at different length positions by a fixing mechanism, and the fixing mechanism mainly includes the cooperation of a locking pin and a positioning hole; the front wheel bracket and the rear wheel bracket can be folded and kept in an open state by a locking mechanism, and the locking mechanism mainly includes a clutch. The telescopic handle assembly is provided on the side of the handle bracket, such as Figure 9 shown.

[0058] A baby stroller according to an embodiment of the present invention includes a telescopic handle assembly. When the second sliding member 5 is configured to slide, the first locking member 6 is disengaged from the positioning hole 11 and the second locking member 7 is disconnected from the locking mechanism. That is, when the first locking member 6 is disengaged from the positioning hole 11 to achieve the handle bracket length adjustment function, the second locking member 7 is disconnected from the locking mechanism that keeps the bracket in an open state and the front wheel bracket and the rear wheel bracket folding function cannot be achieved. At the same time, when the first sliding member 4 is slid, the second locking member 7 drives the locking mechanism to unlock and achieve the front wheel bracket and the rear wheel bracket folding function. At this time, the first locking member 6 cooperates with the positioning hole 11 and the handle bracket length adjustment function cannot be achieved. Therefore, the handle bracket length adjustment function and the front wheel bracket and the rear wheel bracket folding function are selected to achieve one of the handle bracket length adjustment function and the front wheel bracket and the rear wheel bracket folding function. When one of the handle bracket length adjustment function and the front wheel bracket and the rear wheel bracket folding function is achieved, it is effectively avoided that the other function is achieved by mistaken triggering, thereby avoiding danger in use.
