[0039] A mechanical steering column according to an embodiment of the present invention will be described below with reference to the accompanying drawings.
[0040] like Figure 1-Figure 5 As shown, the mechanical steering column 1 according to the embodiment of the present utility model comprises a column body 100 , a base 200 , a sliding connection column 300 and a mechanical adjustment handle 400 .
[0041] The column body 100 is suitable for connecting the steering wheel. The column body 100 has column side plates 101 on both sides. The column side plates 101 are configured with arc grooves 102 that penetrate in the transverse direction. The column body 100 has a limit axis 103 at the arc center of the arc groove 102. The base 200 has base side plates 201 on both sides. The base 200 is configured with a first slide groove 202 and a second slide groove 203 that penetrate in the transverse direction. The first slide groove 202 is located above the second slide groove 203. The limit axis 103 is penetrated in the first slide groove 202 and can slide along the first slide groove 203. The sliding connection column 300 is installed across the column side plates 101 and the base side plates 201. The sliding connection column 300 is penetrated in the arc groove 102 and the second slide groove 203 and can slide along the arc groove 102 and the second slide groove 203. The mechanical adjustment handle 400 is connected to the sliding connection column 300.
[0042] According to the mechanical steering column 1 of the embodiment of the utility model, the upper end of the column body 100 is connected to the steering wheel, and the lower end of the column body 100 is located between the column side plates 101. The sliding connection column 300 between the column side plates 101 and the base side plates 201 can move along the direction in which the arc groove 102 extends, and the sliding connection column 300 can move up and down along the second slide groove 203. When the mechanical steering column 1 needs to be adjusted according to specific requirements, the limit shaft 103 and the sliding connection column 300 will move synchronously, the limit shaft 103 will move up and down along the first slide groove 202 and the sliding connection column 300 will move up and down along the second slide groove 203, wherein the limit shaft 103 and the sliding connection column 300 will reach the uppermost end and the lowermost end of the first slide groove 202 and the second slide groove 203 respectively at the same time. In addition, during the movement, the sliding connection column 300 will also move left and right along the arc of the arc groove 102. When the sliding connection column 300 and the limiting shaft 103 reach the uppermost ends of the second slide groove 203 and the first slide groove 202 respectively, the sliding connection column 300 will synchronously reach the leftmost end of the arc groove 102. When the sliding connection column 300 and the limiting shaft 103 reach the lowermost ends of the second slide groove 203 and the first slide groove 202 respectively, the sliding connection column 300 will synchronously reach the rightmost end of the arc groove 102.
[0043] Through the mechanical steering column 1 of the present embodiment described above, a new rotation mode can be realized. Meanwhile, through the structure of the present embodiment, gas control regulation can also be realized through the present structure.
[0044] Therefore, the mechanical steering column 1 according to the embodiment of the utility model optimizes the adjustment transmission mechanism, has higher structural interchangeability, and has higher versatility.
[0045] In some specific embodiments of the present invention, Figure 1 As shown, the column body 100 includes a column shaft 110 and a connecting bracket 120. The upper end of the column shaft 110 is suitable for connecting the steering wheel, and the lower end of the column shaft 110 is suitable for connecting the steering transmission shaft. The connecting bracket 120 is sleeved on the outer peripheral side of the column shaft 110, and the two sides of the connecting bracket 120 form a column side plate 101. The upper end of the column shaft 110 is connected to the steering wheel, so that the mechanical steering column 1 can be connected to the steering wheel, so that the driver can steer the vehicle through the steering wheel. The column shaft 110, as the connecting part of the steering wheel, provides axial support and stability. The connecting bracket 120 is sleeved on the outer peripheral side of the column shaft 110, and the column side plate 101 is installed on the surrounding sides of the connecting bracket 120. This structure can provide solid support and fixation for the entire mechanical steering column 1 to ensure that the mechanical steering column 1 has sufficient strength and rigidity, can withstand the force and torque generated during steering, and ensure the stability and reliability of steering.
[0046] In some specific embodiments of the present invention, Figure 1 and Figure 2 As shown, the mechanical adjustment handle 400 includes a handle 410 and a damping member 420. The handle 410 is connected to the sliding connection column 300. The damping member 420 is installed between the handle 410 and the base side plate 201. When the handle 410 rotates, the damping member 420 applies pressure to the base side plate 201 to lock the base side plate 201 and the sliding connection column 300.
[0047] The handle 410 is connected to the sliding connection column 300, providing the driver with a convenient operating feel. Through the structure of the handle 410, the driver can easily adjust the angle or height of the mechanical steering column 1, making the driving operation more flexible and comfortable. The damping member 420 is installed between the handle 410 and the base side plate 201. When the handle 410 is rotated, pressure is applied to the base side plate 201, thereby locking the base side plate 201 and the sliding connection column 300, so as to ensure that the position of the adjusted mechanical steering column 1 is firmly fixed, prevent position changes or looseness during driving, and ensure safety and stability during driving.
[0048] In some specific embodiments of the present invention, Figure 2 As shown, the damping member 420 includes a first damping block 421 and a second damping block 422. The first damping block 421 is sleeved on the sliding connection column 300 and connected to the handle 410. The first step surface 401 is configured on the side of the first damping block 421 facing away from the handle 410. The first step surfaces 401 are arranged at intervals along the circumference of the first damping block 421. The second damping block 422 is sleeved on the sliding connection column 300. The second damping block 422 is configured with a second step surface 402 opposite to the first step surface 401. The first step surface 401 and the second step surface 402 are fitted with each other. The first step surface 401 and the second step surface 402 move relative to each other when the handle 410 rotates, so that the second damping block 422 locks the base side plate 201. For example, a diamond structure is constructed on the side of the first damping block 421 and the second damping block 422 away from each other, wherein a diamond groove is constructed at the position of the handle 410 corresponding to the installation of the first damping block 421, and the diamond structure of the first damping block 421 will be embedded in the diamond groove of the handle 410. When the handle rotates, the connection between the two will drive the damping member 420 to rotate.
[0049] Through the interaction and cooperation between the first step surface 401 of the first damping block 421 and the second step surface 402 of the second damping block 422, when the handle 410 rotates, the first step surface 401 and the second step surface 402 move relative to each other, so that the second damping block 422 can lock the base side plate 201. Through the above structure, the base side plate 201 is damped and locked when the handle 410 rotates, ensuring the stability and safety of the position of the mechanical steering column 1.
[0050] In some specific embodiments of the present invention, Figure 2 As shown, the end of the sliding connection column 300 facing the handle 410 is configured with an external gear 301, and the handle 410 is configured with an internal gear gasket 411, and the internal gear gasket 411 is meshed with the external gear 301. The internal gear gasket 411 is respectively connected to the external gear 301 of the handle 410 and another fastener connected to the handle 410, and the internal gear gasket 411 provides both good pressing force and a reliable connection relationship.
[0051] The outer gear 301 and the inner gear gasket 411 are meshed, and this structure can realize precise transmission between the handle 410 and the sliding connection column 300. When the driver rotates the handle 410, the inner gear gasket 411 is meshed with the outer gear 301, thereby transmitting the rotational force to the sliding connection column 300, so that the entire steering mechanism can be operated. The meshing of the inner gear gasket 411 and the outer gear 301 can also ensure the rotation coordination of the handle 410 and the sliding connection column 300, making the driver's steering operation more accurate and smooth. This precise transmission structure can effectively reduce the error during the steering operation and improve the driver's control ability over the steering system.
[0052] In some specific embodiments of the present invention, Figure 5 As shown, the sliding connection column 300 is constructed with multiple flange edges 303 arranged at intervals at corresponding positions of the arc groove 102, and an arc gasket 302 with the same path as the arc groove 103 is constructed between the multiple flange edges 303, and the arc gasket 302 is installed in the arc groove 102.
[0053] The structure of the arc-shaped gasket 302 can effectively reduce the direct contact between the sliding connection column 300 and the arc-shaped groove 102, thereby reducing friction and wear. The arc-shaped gasket 302 and the arc-shaped groove 102 have the same path, so that they can better cooperate and provide buffering and shock absorption effects. By reducing friction and wear, the service life of the sliding connection column 300 can be extended and the maintenance requirements can be reduced. The arc-shaped gasket 302 is tightly matched with the flange edge 303 to form a more reliable connection, which helps to improve the accuracy and controllability of steering.
[0054] In some specific embodiments of the present invention, Figure 3As shown, the outer peripheral side of the limiting shaft 103 is configured with a roller 104, and the roller 104 is matched with the first slide groove 202. The first slide groove 202 can help the limiting shaft 103 or other components to make linear motion in a certain track. When the roller 104 is matched with the first slide groove 202, it can ensure that the limiting shaft 103 makes relative motion along the path specified by the first slide groove 202, and realizes accurate positioning of the relative position. By rolling the roller 104 in the first slide groove 202, the limiting shaft 103 or other components can reduce friction when moving, thereby saving energy and helping to improve the operating efficiency of the overall system.
[0055] In some specific embodiments of the present invention, Figure 1 and Figure 3 As shown, the mechanical steering column 1 further includes a harness fixing plate 500 . The harness fixing plate 500 is installed on the front side of the column body 100 , and both ends of the harness fixing plate 500 extend to the rear of both sides of the column body 100 .
[0056] The harness fixing plate 500 can be used to fix and manage the harness inside the mechanical steering column 1. Specifically, the harness fixing plate 500 is installed on the front side of the column body 100, and its two ends extend to the rear of both sides of the column body 100. Such a structure can effectively organize and constrain the harness, prevent the harness from being confused or damaged during movement or vibration, and ensure its normal and stable working state. Therefore, the harness fixing plate 500 plays an important role in ensuring the functionality and durability of the mechanical steering column 1.
