Description

Universal wheel directional lock Technical Field

[0001] The invention relates to the technical field of wheel steering, in particular to a universal wheel directional lock. Background Art

[0002] Most of the existing vehicles have front wheels as steering wheels that can rotate freely, and rear wheels as fixed wheels that cannot rotate freely. This method does not cause any problems during normal driving. However, when parking sideways or turning around on narrow roads, it requires certain skills and experience, and the operation is very troublesome. Even experienced drivers are not easy to operate, let alone novice drivers. Therefore, it is necessary to improve the steering method of the vehicle. In response to the above problems, an improved universal wheel directional lock is now designed. Technical issues

[0003] Most existing vehicles have steering wheels at the front that can rotate freely, but only to a certain angle. The rear wheels are fixed wheels and cannot turn 360 degrees. This method does not cause any problems during normal driving. However, when parking sideways or turning around in narrow roads, it requires certain skills and experience, and the operation is very troublesome. Even experienced drivers are not easy to operate, let alone novice drivers. Technical Solutions

[0004] The present invention aims to provide a universal wheel directional lock to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A universal wheel directional lock includes a second mounting frame, a first mounting frame mounted on one end of the second mounting frame, a rotating frame horizontally disposed within the second mounting frame, a first rotating rod rotatably connected to a side wall of the rotating frame away from the first mounting frame, a second bevel gear mounted through the side wall of the second mounting frame at the end of the first rotating rod away from the first mounting frame, a third bevel gear mounted on the end of the first rotating rod away from the second bevel gear, and the third bevel gear disposed within the rotating frame. A second rotating rod rotatably connected to a side wall of the rotating frame adjacent to the first mounting frame, a tenth bevel gear mounted through the side walls of the second mounting frame and the first mounting frame at the end of the second rotating rod adjacent to the first mounting frame, a fifth bevel gear mounted on the end of the second rotating rod away from the tenth bevel gear, and the fifth bevel gear disposed within the rotating frame. A fourth bevel gear rotatably connected to an inner wall of the rotating frame between the fifth bevel gear and the third bevel gear, the fourth bevel gear and the third bevel gear being meshed with each other, and the fourth bevel gear and the fifth bevel gear being meshed with each other. A reversing assembly is disposed within the first mounting frame, and a switch assembly is disposed on the first and second rotating rods. As a further solution: the reversing assembly includes a sixth bevel gear, which is rotatably connected to the top of the first mounting frame, and the side of the sixth bevel gear close to the second mounting frame is meshed with the tenth bevel gear, and the side of the sixth bevel gear away from the second mounting frame is meshed with the ninth bevel gear, and a third rotating rod is horizontally installed at the center position of the ninth bevel gear, and the end of the third rotating rod away from the ninth bevel gear passes through the side wall of the first mounting frame to install the seventh bevel gear.

[0007] A further solution: The switch assembly includes a first slot seat and a second slot seat. The first slot seat is mounted on the side wall of the rotating frame away from the first mounting frame. The first slot seat is mounted on a first rotating rod. A first block seat for use with the first slot seat is slidably connected to the side wall of the first rotating rod between the rotating frame and the second mounting frame. The first block seat is connected to the first rotating rod via a slide rail. The second slot seat is mounted on the inner wall of the second mounting frame on the side close to the first mounting frame. The second slot seat is mounted on the second rotating rod. A second block seat for use with the second slot seat is slidably connected to the side wall of the second rotating rod between the rotating frame and the second mounting frame. The second block seat is connected to the second rotating rod via a slide rail.

[0008] A further solution is that reinforcing ribs are installed on the side walls of the rotating frame to improve the structural strength of the rotating frame.

[0009] A further solution is that the first slot seat is mounted on the rotating frame by welding.

[0010] During application, a fixing plate is installed at the lower ends of the second mounting frame and the first mounting frame, and a front steering rod and a rear steering rod are vertically provided at both ends of the fixing plate respectively. The front steering rod and the rear steering rod are rotatably connected to the fixing plate, the lower end of the front steering rod is installed with a front wheel, the upper end of the front steering rod is installed with a first bevel gear passing through the fixing plate, the first bevel gear and the second bevel gear are engaged with each other, the lower end of the rear steering rod is installed with a rear wheel, the upper end of the rear steering rod is installed with an eighth bevel gear passing through the fixing plate, and the seventh bevel gear and the eighth bevel gear are engaged with each other.

[0011] When the vehicle is driving normally, the first block seat is toggled to separate from the first slot seat, and the second block seat is toggled to engage with the second slot seat, so that the second rotating rod cannot rotate, thereby making the fifth bevel gear, the tenth bevel gear, the sixth bevel gear, the ninth bevel gear, the seventh bevel gear, and the eighth bevel gear unable to rotate, thereby fixing the direction of the rear wheels; when the steering component of the vehicle drives the front wheels to turn, the front steering rod drives the first bevel gear to rotate, the front steering rod drives the first bevel gear to rotate, the first bevel gear drives the second bevel gear to rotate, the second bevel gear drives the first rotating rod to rotate, the first rotating rod drives the third bevel gear to rotate, and the third bevel gear drives the fourth bevel gear to roll along the side wall of the fifth bevel gear.

[0012] The first bevel gear is driven by the first gear and the second gear is driven by the second gear. Beneficial effects

[0013] Compared with the prior art, the universal wheel directional lock enables the front wheels to rotate freely and the rear wheels to be fixed by shifting the first block seat to separate from the first slot seat and shifting the second block seat to engage with the second slot seat. At this time, the front wheels and the rear wheels are in the state of normal front and rear wheels of a vehicle, ensuring the normal driving of the vehicle; by shifting the first block seat to engage with the first slot seat and shifting the second block seat to separate from the second slot seat, the front wheels and the rear wheels can rotate simultaneously, and the rotation direction of the rear wheels is the same as that of the front wheels, which is convenient for side parking or U-turning of the vehicle, solving the problems of difficulty in side parking and U-turning on narrow roads, and is easy for users to use.
