Description

Technical Field

[0001] The utility model relates to the technical field of trailers, in particular to a bicycle trailer stabilizing component. Background Art

[0002] A bicycle trailer refers to a body structure installed behind a bicycle with a pulling function, mainly used to place items.

[0003] The Chinese invention patent "A Bicycle Trailer Connection Device Assembly" with existing application number 202210667755.1 discloses that "through the connecting tube and the bearing, when the user is riding a bicycle and turning, the bicycle is fixed through the inner circular wall of the inner ring of the connecting tube and the bearing, so that the angle between the bicycle and the bicycle trailer body can be adjusted to eighty degrees." Among them, the bicycle and the bicycle trailer can only rotate vertically within a limited range relative to each other. If the wheel on one side of the trailer encounters an obstacle and the trailer rolls over, since there is only one degree of freedom in one direction between the bicycle and the trailer, and the trailer generally has too many items and a large mass, there is a risk of the trailer rolling over and causing the bicycle to roll over. Therefore, the present application provides a bicycle trailer stabilizing component to meet the needs. Utility Model Content

[0042] like Figure 1-7As shown, the embodiment of the utility model provides a bicycle trailer stabilizing member, and the bicycle trailer and the bicycle are existing structures and are not described in detail here. Specifically, the bicycle trailer stabilizing member includes:

[0043] like Figure 2 The cross connecting shaft 9 shown is composed of a vertical shaft and a horizontal shaft, the two shafts are fixedly connected, and is used to connect the first connecting member 1 and the third connecting member 3, and the second connecting member 2 and the fourth connecting member 4;

[0044] like Figure 2 The first connecting member 1 shown has the central axis of the first connecting member 1 as the X axis, the vertical axis perpendicular to the central axis as the Y axis, and the horizontal axis perpendicular to the central axis as the Z axis;

[0045] like Figure 3 The second connecting member 2 shown in the figure has a boss 10 convexly provided at the end of the second connecting member 2 along the axial direction, and the first connecting member 1 has a groove concavely provided along the axial direction. The boss 10 is inserted into the groove and is rotatably connected through a bearing 11, so that the first connecting member 1 and the second connecting member 2 can rotate around the X-axis direction;

[0046] like Figure 1 The third connecting member 3 shown is movably connected to the free end of the first connecting member 1 by a cross connecting shaft 9. The first connecting member 1 is rotatably mounted with a vertical shaft along the Y-axis direction, and the third connecting member 3 is rotatably mounted with a horizontal shaft along the Z-axis direction. The first connecting member 1 can rotate around the vertical axis (Y-axis), and the third connecting member 3 can rotate around the horizontal axis (Z-axis). The third connecting member 3 is axially recessed with a sleeve hole 301 for accommodating the tow bar 14, and a third screw hole 302 is opened on the third connecting member 3. The third connecting member 3 and the tow bar 14 are fixedly connected by a third bolt 13 passing through the third screw hole 302;

[0047] like Figure 4 The fourth connecting member 4 shown is movably connected to the free end of the second connecting member 2 by a cross connecting shaft 9. The second connecting member 2 is installed with a vertical axis for rotation along the Y axis direction, and the fourth connecting member 4 is installed with a horizontal axis for rotation along the Z axis direction. The second connecting member 2 can rotate around the vertical axis (Y axis), and the fourth connecting member 4 can rotate around the horizontal axis (Z axis).

[0048] In summary, the third connecting member 3 and the first connecting member 1 have the degree of freedom in the Y-axis and Z-axis directions relative to each other, the first connecting member 1 and the second connecting member 2 have the degree of freedom in the X-axis direction relative to each other, and the second connecting member 2 and the fourth connecting member 4 have free ends in the Y-axis and Z-axis directions relative to each other. When the four groups of connecting members are used in combination, they have the degrees of freedom in multiple directions, which can not only ensure that the bicycle trailer can turn freely with the bicycle, but also reduce the impact of the bicycle or the bicycle trailer on each other when encountering bumps. Even if the trailer rolls over, it will not bring down the bicycle, thereby improving riding safety and effectively ensuring driving stability.

[0049] like Figure 1 and Figure 5 The clamp arm assembly 5 shown includes:

[0050] The telescopic arm 51 is slidably matched with the guide groove 402 axially provided on the fourth connecting member 4. The fourth connecting member 4 is provided with a first screw hole 401. The telescopic arm 51 is provided with a plurality of positioning holes 511. The fourth connecting member 4 and the telescopic arm 51 are fixedly connected by a first bolt 7 passing through the first screw hole 401 and the positioning holes 511.

[0052] Furthermore, if Figure 6 As shown, a dustproof ring 12 is sleeved on the outer side of the boss 10, and the contact surface between the dustproof ring 12 and the first connecting member 1 and the second connecting member 2 is a smooth surface. The smooth surface does not interfere with the relative rotation between the first connecting member 1 and the second connecting member 2. At the same time, it effectively prevents dust from entering the bearing 11, thereby increasing the service life of the bearing 11.

[0053] The technical solution provided by the utility model is to first fix the first clamp arm 52 and the second clamp arm 6 to the bicycle seat tube 15 by the second bolt 8, then insert the trailer rod 14 into the socket hole 301, and fix the two together by the third bolt 13, and then the bicycle trailer can be driven for riding, wherein, since the third connecting member 3 and the first connecting member 1 have the degree of freedom in the Y-axis and Z-axis directions relative to each other, the first connecting member 1 and the second connecting member 2 have the degree of freedom in the X-axis direction relative to each other, and the second connecting member 2 and the fourth connecting member 4 have the free ends in the Y-axis and Z-axis directions relative to each other, the four groups of connecting members have the degree of freedom in multiple directions when used in combination, which can not only ensure that the bicycle trailer can turn freely with the bicycle, but also reduce the influence of the bicycle or the bicycle trailer on each other when encountering bumps, and even when the trailer rolls over, it will not bring down the bicycle, thereby improving riding safety and effectively ensuring driving stability.

[0054] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, the specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details.

[0055] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
