Description

Technical Field

[0001] The utility model belongs to the technical field of camping vehicles and relates to a wheel steering mechanism for a camping vehicle. Background Art

[0002] Existing camping vehicles generally control the forward, backward and steering operations of the camping vehicle through a vertical handle arranged on the camping vehicle. The lower end of the handle is connected to the two wheels through a series of transmission mechanisms. Rotating the handle drives the two wheels to rotate synchronously to achieve steering.

[0003] However, the handlebars of existing camping vehicles need to drive the two wheels to rotate respectively through two sets of transmission mechanisms. The structures of the transmission mechanisms are relatively complex, with many parts, and have the disadvantages of high failure rate and asynchronous rotation of the two wheels. Utility Model Content

[0004] The utility model aims to solve the above problems existing in the steering mechanism of the existing camper and proposes a steering mechanism with simple transmission and high synchronization.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A wheel steering mechanism for a camping vehicle is arranged on a frame of the camping vehicle, and comprises a grip, a wheel, a first rotating shaft, a first connecting rod and a second connecting rod;

[0007] The wheel is rotatably arranged at the bottom of the frame through a wheel frame, the wheel is rotatably arranged on the wheel frame horizontally, and the wheel frame is rotatably arranged on the frame vertically;

[0008] The rotating shaft 1 is vertically rotatably arranged on the vehicle frame, the connecting rod 1 is located between the two wheels and is fixedly connected to the rotating shaft 1, the lower end of the gripping rod is movably connected to the rotating shaft 1, and the gripping rod drives the rotating shaft 1 and the connecting rod 1 to rotate vertically synchronously;

[0009] The left and right ends of the connecting rod 2 are respectively connected to the two wheel frames for rotation, one end of the connecting rod 1 is fixedly connected to the rotating shaft 1, and the other end is rotatably arranged in the middle of the connecting rod 2. When the handle swings left and right, it drives the connecting rod 1 to swing left and right synchronously, so that the connecting rod 2 drives the two wheel frames to swing left and right synchronously for steering.

[0010] In the above-mentioned wheel steering mechanism for camping vehicles, a limit plate is provided on both the left and right sides of the connecting rod 1. When the handle is rotated to the left or right, the left or right limit plate of the connecting rod 1 is relatively close to the connecting rod 2 until the corresponding limit plate abuts against the connecting rod 2, so as to limit the rotation angle of the handle, so as to avoid the rotation angle being too large, resulting in collision between the two wheels after rotation.

[0011] In the above-mentioned wheel steering mechanism for a camper, when the first connecting rod and the second connecting rod are relatively perpendicular, the two wheels remain parallel to the vehicle body.

[0012] In the above-mentioned camping vehicle wheel steering mechanism, a horizontal rotating shaft 2 is fixedly disposed at the lower end of the grip bar, a shaft seat is fixedly disposed at the top of the rotating shaft 1, and the rotating shaft 2 is horizontally rotatably disposed on the shaft seat, so that the grip bar can rotate up and down around the rotating shaft 2. When people of different heights drag the camping vehicle, the grip bar can be adjusted to a suitable angle by rotating it up and down to accommodate users of different heights.

[0013] In the above-mentioned wheel steering mechanism for a camping vehicle, an extension piece is fixedly provided on the wheel frame, and the outer end of the extension piece is rotatably arranged on the second connecting rod.

[0014] Compared with the prior art, the grip of the utility model is connected to the wheel through connecting rod 1 and connecting rod 2, driving the two wheels to rotate synchronously to achieve steering. The steering mechanism of the utility model is simple, with fewer parts and a low failure rate, and the steering synchronization of the two wheels is good. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0022] like Figure 1 and Figure 2As shown, a steering mechanism for a wheel 3 of a camping vehicle described in the utility model is arranged on a frame 1 of the camping vehicle, and comprises a grip 2, a wheel 3, a rotating shaft 1 4, a connecting rod 1 5 and a connecting rod 2 6; the wheel 3 is rotatably arranged at the bottom of the frame 1 through a wheel frame 11, the wheel 3 is horizontally rotatably arranged on the wheel frame 11, and the wheel frame 11 is vertically rotatably arranged on the frame 1.

[0023] like Figure 3 and Figure 4 As shown, the shaft 14 is vertically rotatably arranged on the frame 1, the connecting rod 15 is located between the two wheels 3 and is fixedly connected to the shaft 14, the lower end of the grip 2 is movably connected to the shaft 14, and the grip 2 drives the shaft 14 and the connecting rod 15 to rotate vertically synchronously; the left and right ends of the connecting rod 26 are respectively rotatably connected to the two wheel frames 11, one end of the connecting rod 15 is fixedly connected to the shaft 14, and the other end is rotatably arranged in the middle of the connecting rod 26, when the grip 2 swings left and right, it drives the connecting rod 15 to swing left and right synchronously, so that the connecting rod 26 drives the two wheel frames 11 to swing left and right synchronously for steering. An extension piece 10 is fixedly arranged on the wheel frame 11, and the outer end of the extension piece 10 is rotatably arranged on the connecting rod 26.

[0024] like Figure 5 As shown, a limit plate 7 is provided on both the left and right sides of the connecting rod 1 5. When the handle 2 rotates to the left or right, the limit plate 7 on the left or right side of the connecting rod 1 5 is relatively close to the connecting rod 2 6 until the corresponding limit plate 7 abuts against the connecting rod 2 6, which is used to limit the rotation angle of the handle 2. Avoid excessive rotation angle, which may cause the two wheels 3 to collide after rotation. When the connecting rod 1 5 and the connecting rod 2 6 are relatively vertical, the two wheels 3 remain parallel to the vehicle body.

[0025] A horizontal rotating shaft 2 8 is fixedly disposed at the lower end of the handle 2, and an axle seat 9 is fixedly disposed at the top of the rotating shaft 1 4. The rotating shaft 2 8 is horizontally rotatably disposed on the axle seat 9, so that the handle 2 can rotate up and down around the rotating shaft 2 8. When people of different heights drag the camper, the handle 2 can be adjusted to a suitable angle by rotating it up and down to accommodate users of different heights.
