Description

Technical Field

[0001] This utility model relates to the field of steering column, and in particular to a steering column structure that is easy to install. Background Technology

[0002] The development of the steering column can be traced back to the mid-20th century. Initially, the steering column had a relatively simple structure, its main function being to transmit torque from the steering wheel to the steering gear. To improve driver comfort and ease of operation, the adjustment capabilities of the steering column have continuously evolved. From its initial fixed and non-adjustable state, various adjustment methods have gradually developed, including yaw adjustment, tilt adjustment, and yaw and telescopic adjustment.

[0003] While current steering columns can achieve steering functions, they suffer from inconvenience in installation and difficulty in disassembly and maintenance, resulting in a significant waste of time and reduced work efficiency. Therefore, those skilled in the art have provided a steering column structure that is easy to install to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a directional column structure that is easy to install, enabling rapid installation and disassembly, and allowing for adjustment at different angles, thus greatly improving the flexibility of the directional column.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a directional column structure that is easy to install, comprising a first transmission rod, a second lower end groove fixedly connected to the lower end face of the first transmission rod, a fixing structure provided on the inner and outer walls of the first transmission rod, the fixing structure comprising a second ball joint body, the second ball joint body being located at the inner center of the first transmission rod, the first ball joint body being provided at the lower front end of the first transmission rod, the second ball joint body being provided on both side walls of the second ball joint body, a second connecting plate being provided on the side of the two second ball joint shafts that are far apart from each other, a second top plate being provided on the upper end face of the two second connecting plates, a first ball joint shaft being provided on both side walls of the first ball joint body, a first connecting plate being provided on the side of the two first ball joint shafts that are far apart from each other, a fixing shaft being fixedly connected to the upper end of the side of the two first connecting plates that are close to each other, an electric push rod being fixedly connected to the upper end face of the fixing shaft, and a first top plate being fixedly connected to the output end of the electric push rod;

[0006] Through the above technical solution, the fixing structure is located inside and on the outer wall of the first transmission rod, including the second ball joint body and the first ball joint body. After the second top plate is fixed, since the first top plate is connected to the first connecting plate through the fixing shaft, and the first connecting plate is connected to the first ball joint body through the first ball joint pivot, the movement of the first top plate will drive the first ball joint body to move within a certain range. The second ball joint body is connected to the second connecting plate through the second ball joint pivot, and the second connecting plate is connected to the second top plate, so the angle can be adjusted. Then the electric push rod is started, and its output end pushes the first top plate to move, so that the first top plate fits with the required fixing surface. The movement of the first ball joint body and the second ball joint body can provide a certain degree of flexibility and buffering for the entire directional column structure. At the same time, the first ball joint body and the second ball joint body will not affect the rotation of the first transmission rod. By setting the fixing structure, quick installation and disassembly are achieved, and different angle adjustments can be realized, which greatly improves the flexibility of the directional column.

A third rotating shaft is provided on both outer side walls of the third shaft. The two outer side walls of the two third rotating shafts are rotatably connected to a third lower end groove.

Power is sequentially transmitted from the first transmission rod to the second shaft, the second transmission shaft, the third shaft, and the third transmission rod, and finally output by the helical gear, realizing the transmission function of the steering column.

[0009] Furthermore, a third transmission rod is fixedly connected to the lower end face of the third lower end groove, and a helical gear is fixedly connected to the lower end face of the third transmission rod.

The helical gear transmits the power and motion of the drive shaft to the driven shaft through the meshing of the teeth, thus realizing the transmission of energy and the operation of the machine.

[0011] Furthermore, a second fixing screw is provided at the inner center of the second shaft body, and the second fixing screw passes through the upper and lower end faces of the second lower end groove respectively. A third fixing screw is provided at the inner center of the third shaft body, and the third fixing screw passes through the upper and lower end faces of the third upper end groove respectively.

A third fixing screw is provided at the inner center of the third shaft body. The third fixing screw passes through the upper and lower end faces of the third upper end groove to fix the third shaft body and the third upper end groove, ensuring the stable operation of the transmission structure. During maintenance, a single section can be repaired by disassembling the third fixing screw or the second fixing screw, avoiding the need to disassemble the entire direction column structure due to damage to a small section, thus improving work efficiency.

[0013] Furthermore, a first connecting block is fixedly connected to the rear end face of the first transmission rod, and a steering module is provided at the rear end of the first connecting block.

The protrusion on the steering module is embedded inside the first connecting block and fixed by the first fixing screw passing through the first connecting block and the protrusion. When the steering column structure needs to be repaired, it can be quickly disassembled by removing the first fixing screw. When the steering module receives a steering command, the steering force it generates is transmitted to the first connecting block through the protrusion, thereby driving the first transmission rod to rotate and realizing the steering function of the steering column.

[0015] Furthermore, threaded holes are provided at the four diagonal points inside the first and second top plates;

[0039] The fixing structure 5 is located inside and on the outer wall of the first transmission rod 1, including the second ball joint body 505 and the first ball joint body 504.

[0041] A second fixing screw 12 is provided at the inner center of the second shaft 11.

During maintenance, a single section can be repaired by removing the third fixing screw 16 or the second fixing screw 12, avoiding the need to disassemble the entire direction column structure due to damage to a small section, thus improving work efficiency.

[0042] The helical gear 9 generates a lateral force when the teeth mesh by the inclined angle formed by the tooth surface and the axis. This decomposes the input shaft force into radial force and tangential force. The tangential force generates a circumferential torque that drives the output shaft to rotate. At the same time, due to the different directions of the helix angle, the driving gear and the driven gear rotate in opposite directions, thereby achieving steering. This solution is a commonly used technical means in the prior art, and will not be elaborated on here.
