A parking cable tension structure 100 of an embodiment of the present invention will be described first with reference to fig. 1 to 5.

As shown in fig. 1 to 5, a parking cable tensioning structure 100 according to an embodiment of the present invention may include a pull rod 1, an adjusting portion 2, a cable mounting portion 3, a parking cable 4, and an elastic pre-tightening device (e.g., a pre-tightening spring 5), where one end of the pull rod 1 may be rotatably connected to a parking handle shaft 200, the pull rod 1 includes a positioning section 11, the positioning section 11 may have a plurality of positioning positions in a length direction of the pull rod 1, the adjusting portion 2 may move on the positioning section 11 in the length direction of the pull rod 1, and the adjusting portion 2 may be selectively positioned at one of the positioning positions relative to the positioning section 11.

The adjusting portion 2 can have a one-way positioning function in the length direction of the pull rod 1, that is, when the adjusting portion 2 receives a force in a direction away from the parking cable 4, the adjusting portion 2 can be conveniently separated from the positioning section 11 and move away from the parking cable 4 relative to the pull rod 1 along the length direction of the positioning section 11. When the adjusting portion 2 receives a force in a direction toward the parking cable 4, the adjusting portion 2 is positioned on the positioning section 11 to block the adjusting portion 2 from moving toward the parking cable 4 relative to the lever 1 in a length direction of the positioning section 11.

As shown in fig. 5, to ensure the cable mount 3 is balanced, the pretension F2 of the elastic pretensioning device on the cable mount 3 may be in the opposite direction to the reaction force F1 of the parking cable 4 on the cable mount 3, or the pretension F2 of the elastic pretensioning device on the cable mount 3 may have a component in the opposite direction to the reaction force F1 of the parking cable 4 on the cable mount 3.

The following describes a process of tensioning the parking cable 4 again by the elastic pre-tightening device when the parking cable 4 is pulled for a long time and is stretched and loosened due to plastic deformation of the parking cable 4.

As shown in fig. 1, when the parking cable 4 is loosened, the stress on the cable mounting portion 3 is unbalanced, the elastic pre-tightening device has a tendency of recovering the original length and drives the cable mounting portion 3 to move towards the parking handle shaft 200 relative to the pull rod 1 along the length direction of the pull rod 1, and because the adjusting portion 2 is connected with the cable mounting portion 3, the adjusting portion 2 is separated from the positioning section 11 under the pushing of the cable mounting portion 3 and moves away from the parking cable 4 relative to the pull rod 1 along the length direction of the positioning section 11.

Further, after cable installation department 3 moved to certain distance relative pull rod 1, parking cable 4 tensioning again, 3 atresss rebalancing of cable installation department this moment, cable installation department 3 and regulating part 2 no longer move along the relative pull rod 1 of the length direction of pull rod 1, and location section 11 and regulating part 2 location to hinder regulating part 2 to move towards parking cable 4 along the relative pull rod 1 of the length direction of location section 11, guarantee that parking cable 4 is in the tensioning condition.

According to the parking cable tensioning structure 100 provided by the embodiment of the invention, by arranging the positioning section 11, the adjusting part 2 and the elastic pre-tightening device, when the parking cable 4 is elongated and loosened due to plastic deformation, the elastic pre-tightening device re-tensions the parking cable 4, and the positioning of the positioning section 11 and the adjusting part 2 can ensure that the parking cable 4 is kept in a tensioned state, so that the loosened parking cable 4 does not need to be tensioned manually, and the operation difficulty of tensioning the parking cable 4 is reduced.

In some alternative embodiments of the present invention, as shown in fig. 1 and 2a, the positioning segment 11 may include a rod body 111 and a rack segment 112 disposed on an outer circumferential surface of the rod body 111, the rack segment 112 may be disposed along a length direction of the rod body 111, that is, a tooth slot may be formed between two adjacent teeth of the rack segment 112, a plurality of positioning tooth slots 113 closely arranged along the length direction may be disposed on the rack segment 112, and each positioning tooth slot 113 may form a positioning position that can be positioned with the adjusting portion 2. Therefore, the positioning section 11 can have more positioning positions, so that the tightness of the parking cable 4 can be adjusted more accurately.

As shown in fig. 1, 2a and 3, the regulating portion 2 may include a regulating portion body 21 and a positioning pawl 22 (e.g., a pawl), and the positioning pawl 22 may be rotatably connected with the regulating portion body 21. When the parking cable 4 is in a loose state, the elastic pre-tightening device drives the adjusting part 2 to move relative to the pull rod 1, and the positioning claw 22 can rotate in the positive direction relative to the adjusting part body 21, so that the positioning claw 22 is separated from the positioning tooth groove 113, and the adjusting part 2 moves relative to the pull rod 1. When the parking cable 4 is tensioned, the positioning pawl 22 can rotate reversely relative to the adjusting part body 21, so that the positioning end 221 of the positioning pawl 22 enters one of the positioning tooth grooves 113 to realize the positioning of the adjusting part 2 and the pull rod 1.

In particular embodiments, as shown in fig. 3, each positioning spline 113 may include a riser 1131 and a ramp 1132, the riser 1131 may be perpendicular or approximately perpendicular to the lever body 111 (e.g., may be at an angle of 80 ° -100 ° to the lever body 111), and the ramp 1132 may extend outwardly from an inner end of the riser 1131 in a direction away from the parking cable 4. From this can realize the one-way location of regulating part 2 relative positioning section 11, regulating part 2 can make things convenient for relative positioning section 11 to keep away from parking cable 4 and remove promptly, and hinders regulating part 2 and move towards parking cable 4 along the relative positioning section 11 of length direction of positioning section 11.

The vertex angle of the positioning end 221 can be the same as the included angle between the vertical surface 1131 and the inclined surface 1132 of each positioning tooth groove 113 of the rack segment 112, so that the positioning end 221 is not easy to shake when positioned in the positioning tooth groove 113, and the positioning of the adjusting part 2 and the pull rod 1 is ensured to be firm.

Specifically, as shown in fig. 2a and 3, the adjusting portion body 21 may be provided with a torsion spring 23, one end of the torsion spring 23 may be located with the adjusting portion body 21, the other end of the torsion spring 23 may be fixed with the positioning pawl 22, and an elastic force applied by the torsion spring 23 may enable the positioning pawl 22 to be held in the positioning toothed slot 113, that is, when the parking cable 4 is loosened, the elastic pre-tightening device drives the cable mounting portion 3 and the adjusting portion 2 to move relative to the pull rod 1, the positioning pawl 22 may rotate forward relative to the adjusting portion body 21 under the action of the elastic pre-tightening device to disengage from the positioning toothed slot 113, and at this time, the torsion spring 23 is twisted and stores the twisting energy.

After the cable mounting part 3 moves to a certain distance relative to the pull rod 1, when the parking cable 4 is tensioned again, the force on the cable mounting part 3 is balanced, and at the moment, the torsion spring 23 can release the torsion energy and drive the positioning claw 22 to rotate reversely relative to the adjusting part body 21 so as to be repositioned with the positioning tooth groove 113.

More specifically, as shown in fig. 1 and 2a, the adjusting portion body 21 may include an upper fixing plate 211 and a lower fixing plate 212 that are fastened together, a rotation shaft 2122 and a torsion shaft 2123 may be fixed on an upper surface of the lower fixing plate 212, the positioning pawl 22 may be sleeved on the rotation shaft 2122, the positioning pawl 22 may rotate on the rotation shaft 2122, the torsion spring 23 may be sleeved on the torsion shaft 2123, one end of the torsion spring 23 may penetrate through the lower fixing plate 212 to position the lower fixing plate 212, and the other end of the torsion spring 23 may be fixed to the positioning pawl 22.

Therefore, the positioning pawl 22 and the torsion spring 23 can be disposed between the upper fixing plate 211 and the lower fixing plate 212, and the positioning section 11 can also be disposed between the upper fixing plate 211 and the lower fixing plate 212 in a penetrating manner, so as to ensure that the positioning pawl 22 and the torsion spring 23 are positioned between the upper fixing plate 211 and the lower fixing plate 212.

More specifically, as shown in fig. 2a and 3, the upper surface of the lower fixing plate 212 may further be provided with a limiting post 2124, the limiting post 2124 may be disposed on a side of the positioning pawl 22 away from the positioning segment 11, and the limiting post 2124 may stop against the positioning pawl 22 when the positioning end 221 is away from the rack segment 112, so as to limit the positioning end 221 to continue to be away from the rack segment 112, thereby preventing the positioning pawl 22 from rotating too far and failing to return, and ensuring that the positioning pawl 22 stably operates.

More specifically, as shown in fig. 2a, the lower surface of upper fixing plate 211 may be provided with an upper groove 2111, the upper surface of lower fixing plate 212 may be provided with a lower groove 2121, and when upper fixing plate 211 is fastened to lower fixing plate 212, upper groove 2111 and lower groove 2121 may be opposite to each other to form a receiving groove for receiving shaft body 111, so that the receiving groove may guide the movement of adjusting part 2 relative to shaft body 111, and ensure that adjusting part 2 moves along the length direction of shaft body 111.

In some specific embodiments, as shown in fig. 2b, the cable mounting portion 3 may include an upper mounting plate 31 and a lower mounting plate 32 which are opposite up and down, the upper mounting plate 31 may be fixed with the lower mounting plate 32, the upper mounting plate 31 may be fixed with the upper fixing plate 211, the lower mounting plate 32 may be fixed with the lower fixing plate 212, and the mounting terminal 41 at the end of the parking cable 4 may be fixed with both the upper mounting plate 31 and the lower mounting plate 32.

As shown in fig. 1, when the parking cable 4 is loosened, the cable mounting portion 3 is unbalanced in force, and the elastic pretensioner can compress the guide spring 9 while driving the cable mounting portion 3 to move in the length direction of the tension rod 1. Thus, the guide spring 9 can guide the cable mounting portion 3 when the cable mounting portion 3 moves relative to the drawbar 1, and ensure that the cable mounting portion 3 moves in the longitudinal direction of the drawbar 1.

More specifically, as shown in fig. 1, fig. 2a and fig. 5, the elastic pre-tightening device may include a pre-tightening spring 5, the pre-tightening spring 5 may be sleeved on the spring mounting section 12, the pre-tightening spring 5 may be in a compressed state, the spring mounting section 12 may be sleeved with a first gasket 6, and the first gasket 6 may be located outside the cable mounting section 3 and abut against an end of the cable mounting section 3 away from the positioning section 11.
