Description

Technical Field

[0001] The present application relates to the technical field of child strollers, and in particular to a child stroller. Background Art

[0002] The existing child stroller includes a frame and an adapter seat arranged on the frame, wherein the adapter seat is used to install a seat, wherein the adapter seat can move relative to the frame and has multiple locking positions, generally two. The two locking positions of the adapter seat correspond to different usage states of the child stroller, such as leaving more space for installing other seats, or ensuring the stability of the center of gravity of the child stroller when only one seat is installed.

[0003] However, in the existing structures, a lock slot is provided on the vehicle frame, and a lock member cooperating with the lock slot is movably provided on the adapter seat. Since the adapter seat is located on the inner side of the vehicle frame, the unlocking of the lock member requires an additional unlocking member to drive the lock member out of the lock hole in the movement direction of the lock member. It is based on this unlocking logic that the lock member must be provided on the adapter seat and linked with the unlocking member, that is, the operation logic and structure constrain each other.

[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] It should be noted that when a component is referred to as being "connected" to another component, it may be directly connected to the other component or there may be a central component. When a component is referred to as being "disposed on" another component, it may be directly disposed on the other component or there may be a central component at the same time.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0035] In this application, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number or order of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0036] First, for the convenience of description, the "end" in the text refers to the end point of the structure or a certain point or a certain area in the lateral direction or a specific structure connected to the point or the area.

[0037] See also Figure 1 to Figure 7 The present application provides a child stroller 1000, comprising a frame 100 with a first adapter seat 210, and a first seat 310 detachably mounted on the first adapter seat 210. The first adapter seat 210 is slidably mounted on the frame 100, and a plurality of locking members 400 are movably mounted on the frame 100 on the sliding path of the first adapter seat 210, and the locking members 400 lock the first adapter seat 210 in a corresponding position. The corresponding position includes but is not limited to a higher first position ( Figure 4 ), and a lower second position ( Figure 5 ),like Figure 1 As shown, when installing the second seat 320, the first adapter seat 210 is locked in the first position to avoid the installation space of the second seat 320; Figure 2 As shown, when there is only the first seat 310 on the frame 100, the first adapter seat 210 is locked in the second position to lower the center of gravity of the entire vehicle.

[0038] Among them, the locking member is movably mounted on the frame, so that the unlocking member can be set at any position of the frame, and the two can be remotely linked through a transmission member such as a pull wire, thereby providing more abundant unlocking positions, such as near the top of the handlebar, etc. Even because the first adapter seat is located on the inner side of the frame, combined with the movement direction of the locking member, the locking member itself can be directly driven to unlock and exit the lock hole, thereby saving the unlocking member and the corresponding transmission member, and the structure is simpler, as shown in the following embodiment.

[0039] In one embodiment, the first adapter seat 210 is provided with a lock hole 211, and the locking member 400 has a locking position extending into the lock hole 211, and a release position withdrawing from the lock hole 211. The first adapter seat 210 is arranged on the inner side of the frame, the locking member 400 has an operating portion 410, and when the locking member 400 is in the locked position, the lock hole 211 is open to expose the operating portion 410 to facilitate the unlocking operation. Specifically, the lock hole 211 is a through hole, and the operating portion 410 is located on the end face of the locking member 400. That is, the locking member 400 also serves as an unlocking member, and the unlocking member is located on the first adapter seat 410, which is in line with the unlocking habit.

[0040] The child stroller includes an elastic member 500 that acts on the locking member 400 to switch it from the unlocking position to the locking position. The elastic member 500 may be a spring or a torsion spring, etc., which needs to be determined in combination with the motion relationship of the locking member 400. In the figure, the locking member 400 is slidably mounted on the frame 100, and the corresponding elastic member 500 is a spring, which acts on the frame 100 and the locking member 400 respectively. The sliding direction of the locking member 400 and the sliding direction of the first adapter seat 210 are perpendicular to each other, and the interaction effect of the forces is optimal.

[0041] The frame 100 is fixedly provided with a guide rail 131, the first adapter seat 210 is slidably mounted on the guide rail 131, and the locking member 400 is also slidably mounted on the guide rail 131. The inner side surface of the guide rail 131 is a plane, and the locking member 400 protrudes from the plane when it is in the locked position. The first adapter seat 210 has a guide portion 212 that presses the locking member 400 and compresses the elastic member 500 during the sliding process. When the locking hole 211 is aligned with the locking member 400, the elastic member 500 resets and drives the locking member 400 to extend into the locking hole 211. In the figure, the openings at both ends of the first adapter seat 210 along its own sliding direction are provided with guide portions 212.

[0042] See also Figure 8 and Fig. 9 In one embodiment, the frame 100 includes a front foot assembly 110, a rear foot assembly 120 and a handlebar assembly 130, and the first adapter seat 210 is slidably mounted on the handlebar assembly 130. The front foot assembly 110 and the handlebar assembly 130 are substantially in the same straight line, and the child stroller 1000 includes a second adapter seat 220 mounted on the front foot assembly 110, and a second seat 320 detachably mounted on the second adapter seat 220, and the second adapter seat 220 is detachably mounted on the front foot assembly 110.

[0043] As for the assembly relationship between the second adapter seat 220 and the front foot assembly 110, the front foot assembly 110 includes a U-shaped rod and a wheel installed at the bottom of the U-shaped rod, and the second adapter seat 220 includes a first connecting member 221 and a second connecting member 222 that are hinged to each other, and the second connecting member 222 has a socket connected to the second seat 320. The first connecting member 221 and the second connecting member 222 have a combined state of embracing the U-shaped rod, and a relatively separated state, in which the second adapter seat 220 is allowed to be separated from the front foot assembly 110.

[0044] The first connecting member 221 and the second connecting member 222 are provided with a locking structure for keeping the two in a combined state, and a corresponding releasing member for unlocking the locking structure.

[0045] The child stroller of the present application has a locking member movably mounted on the frame, so that an unlocking member can be set at any position of the frame, and the two can be remotely linked through a transmission member such as a pull wire, thereby providing a richer unlocking position, such as near the top of the handlebar, etc.; even because the first adapter seat is located on the inner side of the frame, combined with the movement direction of the locking member, the locking member itself can be directly driven to unlock and exit the lock hole, thereby saving the unlocking member and the corresponding transmission member, and the structure is simpler.

[0046] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. When the technical features in different embodiments are embodied in the same figure, it can be regarded that the figure also discloses the combination examples of the various embodiments involved.

[0047] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
