Description

Technical Field

[0001] The utility model relates to the technical field of automobile steering systems, and more specifically to an environmentally friendly multi-directional adjustable light truck steering column. Background Art

[0002] With the development of science and technology, the competition in the light truck industry is becoming increasingly fierce. Users have higher and higher requirements for the comfort, reliability and maneuverability of the whole vehicle, which also puts higher requirements on the parts of the whole vehicle. At present, the steering column of the light truck can adjust the steering wheel forward and backward. The forward and backward adjustment of the steering wheel is achieved by adjusting the steering column forward and backward. First, an adjustment device is needed to fix it. When the steering column is fixed on the device, the forward and backward adjustment can be achieved.

[0003] After searching, the Chinese patent application number CN201520045644.2 discloses "a front-to-rear adjustment device for a light truck steering column, including a locking bolt, an adjustment handle, a locking nut, a movable screw, a guide rail bracket, a movable bracket and a protective bracket...";

[0004] This patent realizes the rotation of the adjusting handle within a certain angle range through the structure of the adjusting handle and the movable bracket, thereby realizing the locking and loosening of the adjusting handle. Among them, during the locking and loosening operation, the movable screw is mainly locked by rotating the adjusting handle to make the locking nut contact with the guide rail bracket. Although this locking can limit the translational movement of the movable screw, when the screw and the locking nut are stripped, the locking nut will not be able to limit the rotation of the movable screw, which will cause the steering wheel to be unable to be locked and to swing, which can bring great safety risks to driving. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the utility model provides an environmentally friendly multi-directional adjustable light truck steering column, which has the advantage of being able to stably limit the rotation of a screw rod.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an environmentally friendly multi-directional adjustable light truck steering column, comprising a mounting frame one, on which a U-shaped frame is fixedly mounted, an adjustment component is mounted on the inner side of the U-shaped frame, the adjustment component comprises a mounting frame two, on the inner side of the mounting frame two a rotating shaft is fixedly mounted, the two ends of the rotating shaft are respectively slidably connected to the two ends of the inner side of the U-shaped frame, a limit block is fixedly mounted on one end of the rotating shaft, and a locking member is mounted on the other end of the rotating shaft for locking the rotating shaft.

[0007] As a preferred technical solution of the utility model, both ends of the mounting frame 1 are provided with positioning holes, and the mounting frame 1 is mounted on the vehicle body by cooperating with bolts in the positioning holes.

[0008] As a preferred technical solution of the utility model, two first mounting holes are provided on the mounting frame, and two second mounting holes corresponding to the first mounting holes are provided at one end of the U-shaped frame, and the second mounting holes are connected to the first mounting holes by the same bolt.

[0009] As a preferred technical solution of the utility model, both sides of the U-shaped frame are provided with sliding grooves matching the rotating shaft, and both ends of the rotating shaft slide along the corresponding sliding grooves.

[0010] As a preferred technical solution of the utility model, the locking piece includes a threaded strip, which is fixedly mounted on one end of the rotating shaft, a positioning nut is threadedly mounted on one end of the threaded strip, an internal threaded sleeve is also threadedly mounted on the threaded strip, the internal threaded sleeve is located on one side of the positioning nut, and a handle is fixedly mounted on the outer side of the internal threaded sleeve.

[0011] As a preferred technical solution of the utility model, a sliding sleeve is provided at one end of the rotating shaft, and the sliding sleeve slides along the axial direction of the rotating shaft and can contact the internal threaded sleeve. A locking plate is fixedly installed at one end of the sliding sleeve, and the locking plate can be tightly attached to the side wall of the U-shaped frame.

[0012] As a preferred technical solution of the utility model, a card slot is provided on the rotating shaft, and a card block is fixedly installed on the inner side of the sliding sleeve. The card block cooperates with the card slot and can slide along the card slot.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The self-rotation of the rotating shaft can cause the second mounting frame to self-rotate, so that the angle of the second mounting frame can be adjusted, thereby realizing multi-directional adjustment of the steering wheel;

[0015] 2. When locking, the handle is turned to make the internal thread sleeve and the threaded strip rotate relative to each other, which makes the internal thread sleeve approach the sliding sleeve and exert pressure on it, so that the sliding sleeve drives the locking plate to contact the U-shaped frame, so that the locking plate and the U-shaped frame are tightly attached, and the static friction between the locking plate and the U-shaped frame can limit the sliding of the rotating shaft; the block and the slot can limit the relative rotation between the rotating shaft and the sliding sleeve. Since the sliding sleeve is restricted by the locking plate, the rotating shaft is restricted and cannot rotate, which can ensure that the rotating shaft can be stably locked, effectively avoiding the problem of the steering wheel swinging due to the loosening of the second mounting frame, and greatly improving driving safety.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 5 As shown, the utility model provides an environmentally friendly multi-directional adjustable light truck steering column, including a mounting frame 1, a U-shaped frame 2 is fixedly mounted on the mounting frame 1, an adjustment assembly 3 is installed on the inner side of the U-shaped frame 2, and the adjustment assembly 3 includes a mounting frame 2 31, a rotating shaft 33 is fixedly mounted on the inner side of the mounting frame 2 31, and the two ends of the rotating shaft 33 are respectively slidably connected with the two ends of the inner side of the U-shaped frame 2, a limited block 34 is fixedly mounted on one end of the rotating shaft 33, and a locking member 35 is installed on the other end of the rotating shaft 33 for locking the rotating shaft 33. By translating the rotating shaft on the U-shaped frame 2, the upper and lower positions of the mounting frame 2 31 can be adjusted; the self-rotation of the rotating shaft 33 can make the mounting frame 2 31 rotate, so that the angle of the mounting frame 31 can be adjusted, so that the multi-directional adjustment of the steering wheel can be realized.

[0024] Among them, positioning holes 11 are opened at both ends of the mounting frame 1, and the positioning holes 11 are used to mount the mounting frame 1 on the vehicle body by cooperating with bolts.

[0025] The mounting frame 1 has two first mounting holes 12 , and one end of the U-shaped frame 2 has two second mounting holes 21 corresponding to the first mounting holes 12 . The second mounting holes 21 are connected to the first mounting holes 12 by the same bolt.

[0026] Among them, both sides of the U-shaped frame 2 are provided with slide grooves 22 matching the rotating shaft 33, and the two ends of the rotating shaft 33 slide along the corresponding slide grooves 22. The slide grooves 22 can guide the rotating shaft 33, so that the rotating shaft 33 can be ensured to remain stable during the movement.

[0027] Among them, the locking member 35 includes a threaded strip 351, which is fixedly mounted on one end of the rotating shaft 33, a positioning nut 352 is threadedly mounted on one end of the threaded strip 351, an internal threaded sleeve 353 is also threadedly mounted on the threaded strip 351, the internal threaded sleeve 353 is located on one side of the positioning nut 352, and a handle 354 is fixedly mounted on the outer side of the internal threaded sleeve 353; a sliding sleeve 355 is sleeved on one end of the rotating shaft 33, the sliding sleeve 355 slides along the axial direction of the rotating shaft 33 and can contact the internal threaded sleeve 353, a locking plate 356 is fixedly mounted on one end of the sliding sleeve 355, and the locking plate 356 can be tightly attached to the side wall of the U-shaped frame 2; a slot 358 is opened on the rotating shaft 33, a block 357 is fixedly mounted on the inner side of the sliding sleeve 355, and the block 357 cooperates with the slot 358 and can slide along the slot 358.

[0028] During installation, the positioning nut 352 is installed at the end of the rotating shaft 33 and is threadedly fixed with the thread strip 351, so that the internal thread sleeve 353 can be restricted to prevent the internal thread sleeve 353 from being separated from the rotating shaft 33 during rotation;

[0029] When locking, the handle bar 354 is rotated to make the internal threaded sleeve 353 and the threaded strip 351 rotate relative to each other, which makes the internal threaded sleeve 353 approach the sliding sleeve 355 and apply pressure to it, so that the sliding sleeve 355 drives the locking plate 356 to contact the U-shaped frame 2, so that the locking plate 356 and the U-shaped frame 2 are tightly attached, and the static friction between the locking plate 356 and the U-shaped frame 2 can limit the sliding of the rotating shaft 33; and the block 357 and the groove 358 can limit the relative rotation between the rotating shaft 33 and the sliding sleeve 355. Since the sliding sleeve 355 is restricted by the locking plate 356, the rotating shaft 33 is restricted and cannot rotate. In this way, it can be ensured that the rotating shaft 33 can be stably locked, and the problem of the steering wheel swinging due to the loosening of the mounting frame 2 31 is effectively avoided, thereby greatly improving driving safety.
