[0001] This utility model relates to an auxiliary support structure. [Background Technology]

[0002] Currently, most two-wheeled children's bikes on the market designed for younger children have a support structure. When a child is just learning to ride, the support structure is attached to the frame, allowing three wheels to touch the ground and preventing the bike from tipping over. As the child becomes more skilled and their balance needs to be improved, the support structure is removed from the frame, allowing the bike to be ridden as a balance bike with both front and rear wheels on the ground. Therefore, the support structure needs to be frequently removed and installed during the use of the bike. Since the support structure is usually attached to the frame with screws, this process is inconvenient, time-consuming, and laborious.

[0003] Therefore, this utility model was created based on the above-mentioned shortcomings. [Utility Model Content]

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide an auxiliary support structure that is simple in structure and easy to assemble and disassemble.

Detailed Implementation Methods

[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] like Figures 1 to 5 As shown, an auxiliary support structure includes a support base 1 that can be connected to a vehicle frame 100. A support rod 2 is connected to the support base 1. The support base 1 is provided with a slot 11 into which the end of the support rod 2 can be inserted. A locking component 3 is provided between the support base 1 and the support rod 2, which can lock the two when the support rod 2 is inserted into the support base 1. The locking component 3 includes a locking position 31 provided on the support rod 2. The support base 1 is provided with a movable member 32 that can move relative to it. The top of the movable member 32 is provided with a snap-fit ​​part 321 that can snap into the locking position 31. An elastic member 33 is provided between the movable member 32 and the support base 1, which can keep the snap-fit ​​part 321 snapped into the locking position 31.

[0029] In practical use, the auxiliary support structure of this utility model is connected to both the left and right sides of the stroller. When the auxiliary support structure needs to be installed, the support rod 2 is aligned with the slot 11 of the support seat 1, and then the support rod 2 is pushed upward so that the snap-fit ​​part 321 on the movable part 32 can snap into the locking position 31 on the support rod 2. At this time, the support rod 2 can be locked on the support seat 1. When the support rod 2 needs to be removed, press the movable part 32 so that the snap-fit ​​part 321 is disengaged from the locking position 31. The user can pull the support rod 2 downward to pull the support rod 2 out of the support seat 1. The disassembly and assembly are very convenient.

[0030] Of course, in one embodiment, one end of the support rod 2 is connected to a wheel. It is conceivable that in another embodiment, the other end of the support rod 2 could also be a rotatable foot support.

[0031] like Figure 4 As shown, the locking position 31 is a plug groove provided on the support rod 2 and into which the snap-fit ​​part 321 can be inserted. At the same time, the top surface of the plug groove can abut against the snap-fit ​​part 321 to prevent the support rod 2 from disengaging from the support base 1, thus ensuring a stable lock.

[0032] like Figures 2 to 3 As shown, the support base 1 includes a connecting plate 12, a connecting block 13, and a housing 14 that are interconnected. The connecting plate 12, the connecting block 13, and the housing 14 are connected sequentially, and a slot 11 is formed between the connecting plate 12, the connecting block 13, and the housing 14 to allow the support rod 2 to be inserted. The connecting plate 12, the connecting block 13, and the housing 14 are connected and fixed by quick-connect components such as screw assemblies, making connection and installation convenient.

[0033] like Figure 5 As shown, the connecting plate 12, connecting block 13 and housing 14 are provided with connecting holes 15 that can be connected to the frame 100. This arrangement makes it easy for the three to be on the same axis, which is convenient for positioning and installation, and at the same time, it is more stable when connected to the frame 100.

[0034] like Figures 2 to 3 As shown, the connecting block 13 has a protruding part 131, the connecting hole 15 passes through the protruding part 131 and the connecting block 13, and the support rod 2 has a positioning groove 21 into which the protruding part 131 can be engaged. The protruding part 131 is provided for positioning and can cooperate with the positioning groove 21 to prevent the support rod 2 from wobbling relative to the support base 1 in the front and back direction.

[0035] like Figures 2 to 3 As shown, the cross-section of the support rod 2 is U-shaped. This design makes the support rod 2 more stable when it is snapped and fixed to the support base 1. Moreover, the support rod 2 has high structural strength and is not easily deformed.

[0036] like Figure 3 As shown, the connecting plate 12 has a groove 121, and the connecting block 13 has a snap-fit ​​protrusion 132 that can be snapped into the groove 121. When the connecting plate 12 and the connecting block 13 are snapped together, the rear side 133 of the connecting block 13 is flush with the back side 122 of the connecting plate 12. This flush arrangement of the rear side 133 of the connecting block 13 with the back side 122 of the connecting plate 12 results in a smaller volume when the two are connected, and a tighter and more stable connection.

[0037] like Figures 2 to 3 As shown, the movable component 32 is rotatably connected to the connecting block 13, and the connecting block 13 is also provided with a movable space 134 within which the movable component 32 can rotate. The movable space 134 facilitates the rotation of the movable component 32.

[0038] like Figures 2 to 3 As shown, the outer shell 14 is provided with two protruding positioning parts 141 on both sides, and the connecting plate 12 is provided with a snap-fit ​​groove 123 that allows the connecting part 323 to be snapped into. The length of one of the positioning parts 141 is longer than that of the other positioning part 141. This arrangement allows the longer positioning part 141 to be snapped into the frame 100, which is convenient for positioning and installation.

[0039] like Figures 2 to 3 As shown, the outer shell 14 is also provided with a downward protruding top part 142 that can abut against the support rod 2. The top part 142 can prevent the support rod 2 from swaying relative to the support seat 1 in the left and right directions of the frame 100, thus providing more stable support.

[0040] like Figures 2 to 3 As shown, the movable part 32 includes a strip-shaped body 322 rotatably connected to the connecting block 13 via a pin. A protruding snap-fit ​​part 321 is connected to the strip-shaped body 322. A twisted connecting part 323 and a pressing piece 324 are connected to the lower end of the strip-shaped body 322. The strip-shaped body 322 is vertically arranged. The connecting part 323 causes the pressing piece 324 to be twisted at 90° relative to the strip-shaped body 322. This arrangement makes the pressing piece 324 horizontally arranged, which facilitates the user's pressing operation.

[0041] like Figures 6 to 10As shown, in another embodiment, the movable component 32 includes a plate-shaped body 325. Rotating portions 3251 are connected to both ends of the plate-shaped body 325. The connecting block 13 is provided with a rotational space 135 within which the rotating portions 3251 can move. The connecting block 13 is also provided with a guide groove 136 that communicates with the rotational space 135 and guides the rotating portions 3251 into the rotational space 135. A snap-fit ​​portion 321 is connected to the top end of the plate-shaped body 325, and a pressing portion 326 is connected to the lower end of the plate-shaped body 325. The guide groove 136 facilitates the connection of the plate-shaped body 325 to the connecting block 13 via the rotating portions 3251.

[0042] The present invention has been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the invention.
