[0041] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0042] Reference below Figure 1-Figure 7 Description According to an embodiment of the utility model, the adjusting link 100 includes a first rod body 1, a second rod body 2 and a locking member 3. The first rod body 1 is formed with a guide space 10a. The second rod body 2 can be movably assembled in the guide space 10a to adjust the length of the adjusting link 100. Along the length direction of the adjusting link 100, when the second rod body 2 moves toward the direction close to the first rod body 1, the length of the adjusting link 100 decreases. When the second rod body 2 moves toward the direction away from the first rod body 1, the length of the adjusting link 100 increases, thereby achieving the effect of adjusting the length of the adjusting link 100. The locking member 3 is assembled on the first rod body 1 and cooperates with the second rod body 2 to fix the first rod body 1 and the second rod body 2, thereby limiting the relative position of the first rod body 1 and the second rod body 2, and achieving the effect of the first rod body 1 and the second rod body 2 being in a locked state.

[0043] Specifically, Figure 2-Figure 6 As shown, the second rod body 2 is formed with a matching portion 20a, and the first rod body 1 is formed with a through hole 10b. When the second rod body 2 is assembled in the guide space 10a, the through hole 10b is arranged corresponding to the matching portion 20a. The locking member 3 is penetrated in the through hole 10b, and the locking member 3 is suitable for limited position cooperation with the matching portion 20a, so as to fix the first rod body 1 and the second rod body 2. When the locking member 3 is limited position cooperation with the matching portion 20a, the relative position of the first rod body 1 and the second rod body 2 is limited in the length direction of the adjustment link 100. When the locking member 3 is separated from the matching portion 20a, the position relationship restriction between the first rod body 1 and the second rod body 2 is released in the length direction of the adjustment link 100, so that the adjustment link 100 can be extended or shortened.

[0044] Thus, by limiting the engagement or separation of the locking member 3 and the mating portion 20a, the first rod body 1 and the second rod body 2 are put into a locked state or an unlocked state. Therefore, the adjustment connecting rod 100 according to the embodiment of the utility model is easy to operate during the process of adjusting the length of the adjustment connecting rod 100.

[0045] In addition, the second rod body 2 is assembled in the guide space 10a of the first rod body 1, so most of the structure of the second rod body 2 can be stored in the guide space 10a, so that the length difference between the shortest length and the maximum length of the adjustment link 100 is large. Therefore, the adjustment link 100 according to the embodiment of the utility model has the advantage of a large adjustment range and can be suitable for a variety of usage scenarios.

[0046] In some embodiments of the present invention, Figure 1-Figure 3 and Figure 6 As shown, a matching portion 20 a is formed on the outer peripheral wall of the second rod body 2 , and the matching portion 20 a is configured as a rack. The locking member 3 is engaged with the rack to limit the second rod body 2 from moving relative to the first rod body 1 .

[0047] In some embodiments, in combination Figure 1-Figure 3 and Figure 6 As shown, the rack is extended along the length direction of the second rod body 2, meshed with the rack through the locking member 3, and the locking member 3 is fixedly connected to the first rod body 1, thereby limiting the movement of the second rod body 2 relative to the first rod body 1, so as to limit the relative position of the first rod body 1 and the second rod body 2 in the length direction of the adjusting connecting rod 100.

[0048] In addition, it should be supplemented that the matching portion 20 a is set as a rack. Since the rack has multiple teeth, the locking member 3 can be limitedly matched with at least one of the multiple teeth to improve the adjustment accuracy of the adjustment link 100.

[0049] In some embodiments of the present invention, the matching portion 20 a is configured as a limiting hole, and the locking member 3 is assembled in the limiting hole to limit the movement of the second rod body 2 relative to the first rod body 1 .

[0050] In some embodiments, the second rod body 2 is formed with a plurality of limiting holes, and the plurality of limiting holes are arranged in sequence along the length direction of the second rod body 2, and the limiting holes are arranged corresponding to the penetration hole 10b. When the locking member 3 is penetrated in the penetration hole 10b, the locking member 3 extends into one of the plurality of limiting holes so that the locking member 3 is limitedly matched with the limiting hole to limit the movement of the second rod body 2 relative to the first rod body 1, so as to limit the relative position of the first rod body 1 and the second rod body 2 in the length direction of the adjusting connecting rod 100.

[0051] In some embodiments of the present invention, Figure 3 As shown, the locking member 3 includes a fixing bolt 31 and a limiting tooth body 32. The limiting tooth body 32 is rotatably assembled on the fixing bolt 31. The fixing bolt 31 is fixedly matched with the second rod body 2. The limiting tooth body 32 is penetrated through the penetration hole 10b and meshed with the rack.

[0052] During the process of fixing the locking member 3 to the second rod body 2, the limiting tooth body 32 moves into the guide space 10a through the through hole 10b so that the limiting tooth body 32 is meshed with the rack, and the outer peripheral wall of the fixing bolt 31 is formed with an external thread, and the second rod body 2 is formed with an internal thread that is threadedly matched with the fixing bolt 31, so that the fixing bolt 31 is threadedly fixed to the second rod body 2. Since the fixing bolt 31 rotates around its own axis during the process of threading the fixing bolt 31 and the second rod body 2, the limiting tooth body 32 can be rotatably assembled to the fixing bolt 31. During the rotation of the fixing bolt 31, the limiting tooth body 32 is prevented from rotating, so that the fixing bolt 31 can rotate and be fixed to the second rod body 2, thereby preventing the locking member 3 from being separated from the second rod body 2.

[0053] Since the limiting tooth body 32 and the fixing bolt 31 can rotate relative to each other, the force driving the fixing bolt 31 to rotate cannot be further transmitted to the rack through the limiting tooth body 32, which also protects the tooth shape of the rack. In addition, when the first rod body 1 and the second rod body 2 move relative to each other along the length direction of the adjusting link 100, the second rod body 2 applies a force along the first direction to the limiting tooth body 32. Since the limiting tooth body 32 and the fixing bolt 31 can rotate relative to each other, the force acting on the limiting tooth body 32 cannot be further transmitted to the fixing bolt 31, thereby preventing the fixing bolt 31 from loosening and improving the reliability of the adjusting link 100.

[0054] In some embodiments, the limiting tooth body 32 has at least one limiting tooth 320. Figure 3 As shown, the limiting tooth body 32 has a limiting tooth 320. When the locking member 3 is limitedly matched with the rack, the limiting tooth 320 is located in the tooth gap of the rack, so that in the extension direction of the rack, the limiting tooth 320 abuts against the teeth of the rack, thereby achieving the limiting matching effect of the limiting tooth body 32 and the rack.

[0055] It should be noted that, in the above-mentioned embodiment, the limiting tooth body 32 is described as having one limiting tooth 320, but the present application is not limited thereto. The limiting tooth body 32 has two limiting teeth 320 or another number of limiting teeth 320, and each limiting tooth body 32 corresponds one-to-one with each tooth gap of the rack, thereby achieving the effect of limiting cooperation between the limiting tooth body 32 and the rack.

[0056] In some embodiments, when the limiting tooth body 32 has multiple limiting teeth 320, when one of the multiple limiting teeth 320 is damaged, the other limiting teeth 320 in the multiple limiting teeth 320 still cooperate with the rack to limit the position, thereby improving the reliability of the limiting tooth body 32 and the rack to limit the position and reducing the risk of failure of the locking member 3.

[0057] In some embodiments of the present invention, the inner wall of the penetration hole 10b is formed with a guide surface, and the outer wall of the limiting tooth body 32 is formed with a guide matching surface, and the guide matching surface is matched with the guide surface, so as to facilitate the limiting tooth body 32 to penetrate the penetration hole 10b and improve the assembly efficiency.

[0058] In some embodiments of the present invention, Figure 4-Figure 6 As shown, the first rod body 1 includes a first rod body 11 and a first connecting member 12, and the first connecting member 12 can be movably assembled at an end of the first rod body 11 away from the second rod body 2.

During the driving of the vehicle, the adjusting link 100 rotates synchronously with the bouncing of the vehicle body to control the rotation angle of the height valve, and the internal air pressure of the airbag shock absorber is adjusted by adjusting the internal gas flow, thereby achieving stiffness adjustment and improving the comfort of the vehicle body.

[0060] In some embodiments, Figure 5 As shown, a guide space 10a is formed in the first rod body 11, and an assembly opening 10c is formed at one end of the first rod body 11 away from the first connecting member 12. The assembly opening 10c is constructed as an opening of the guide space 10a, and the second rod body 21 is assembled in the guide space 10a through the assembly opening 10c to achieve the effect of coordinated assembly of the first rod body 1 and the second rod body 2.

[0062] In some embodiments, Figure 5 As shown, the barrel 11a and the first connecting ball head 11b are integrally formed, thereby ensuring the structural strength of the first rod body 11 to prevent the barrel 11a and the first connecting ball head 11b from being separated from each other. In other embodiments, the first connecting ball head 11b is detachably assembled to the barrel 11a, so that different types of first connecting ball heads 11b can be replaced, so that the first rod body 11 can be adapted to different types of first connecting members 12, thereby improving the versatility of the first rod body 11.

[0066] In some embodiments of the present invention, Figure 1-Figure 3 and Figure 6 As shown, the outer peripheral wall of the guide rod body 21a is formed with a matching portion 20a. When the guide rod body 21a extends into the guide space 10a, the matching portion 20a is correspondingly arranged with the through hole 10b, so that the locking member 3 penetrated through the through hole 10b is limitedly matched with the matching portion 20a.
