Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a stabilizer link and a vehicle. Background Art

[0002] The stabilizer bar connecting rod connects the stabilizer bar to the shock absorber. Its primary function is to reduce the vehicle's lateral roll during cornering, thereby improving cornering comfort. Due to cost control concerns, some vehicles use a cold-bending process to manufacture the stabilizer bar. However, the dimensional instability of cold-bending processes can lead to a height difference between the left and right ends of the stabilizer bar, further affecting the clearance between the left and right wheel arches and the ground.

[0003] To address the height difference between the left and right wheel arches caused by the height difference between the left and right end connection points of the stabilizer bar, related structures have adopted an adjustable stabilizer bar link. For example, some stabilizer bar links are adjusted in length using a hydraulic cylinder, but this results in high costs. Other stabilizer bar links are adjusted in length by threading two sections together, but this method is inefficient. Utility Model Content

[0004] Based on this, it is necessary to provide a stabilizer link that can adjust the length efficiently and at low cost.

[0005] A stabilizer bar connecting rod is used to connect a stabilizer bar and a shock absorber. The stabilizer bar connecting rod includes a first rod, a second rod and an adjusting rod. One end of the first rod is used to connect the stabilizer bar, and the other end is provided with a first threaded hole. One end of the second rod is used to connect the shock absorber, and the other end is provided with a second threaded hole. The adjusting rod has a first threaded portion and a second threaded portion. The first threaded portion is threadedly connected to the first threaded hole, and the second threaded portion is threadedly connected to the second threaded hole. The thread directions of the first threaded hole and the second threaded hole are opposite, so that when the adjusting rod rotates around its own axis, the first rod and the second rod can move toward or away from each other along the axis of the adjusting rod.

[0006] In one embodiment, the stabilizer rod link also includes a first locking nut, which is sleeved on the first threaded portion, and the first locking nut has a locking state locked to the first threaded portion and an unlocked state capable of moving relative to the first threaded portion; when the first locking nut is in the locked state, the first locking nut is used to cooperate with the first rod stop.

[0007] In one embodiment, the stabilizer link further includes a second locking nut, which is sleeved on the second threaded portion, and the second locking nut has a locked state locked to the second threaded portion and an unlocked state capable of moving relative to the second threaded portion; when the second locking nut is in the locked state, the second locking nut is used to cooperate with the second rod stop.

[0008] In one embodiment, the adjusting rod is further provided with a screwing portion, and along the axial direction of the adjusting rod, the screwing portion is located between the first threaded portion and the second threaded portion.

[0009] In one embodiment, the screwing portion is configured as a hexagonal head.

[0010] In one embodiment, the first threaded portion, the second threaded portion and the screwing portion are an integrated structure.

[0011] In one embodiment, the stabilizer link further includes a first mounting seat and a first ball pin, the first mounting seat is fixedly connected to the end of the first rod away from the first threaded hole, the first ball pin is rotatably mounted on the first mounting seat, and is used to connect the stabilizer link.

[0012] In one embodiment, the stabilizer link further includes a second mounting seat and a second ball pin, the second mounting seat is fixedly connected to the end of the second rod away from the second threaded hole, the second ball pin is rotatably mounted on the second mounting seat, and is used to connect to the shock absorber.

[0013] The present application also provides a vehicle, which includes a stabilizer bar, two shock absorbers and two or more stabilizer bar links implemented as described above. In each stabilizer bar link, the end of the first rod away from the first threaded hole is connected to the stabilizer bar, and the end of the second rod away from the second threaded hole is correspondingly connected to a shock absorber.

[0014] In one embodiment, along the height direction of the vehicle, the positions where the two stabilizer bar links are connected to the stabilizer bar are at the same height, and the positions where the two stabilizer bar links are connected to the corresponding shock absorbers are at the same height.

[0015] Compared to the prior art, the stabilizer link and vehicle provided by the present application have opposite thread directions for the first and second threaded holes. Therefore, when the adjustment rod is turned clockwise or counterclockwise, the first and second rods move toward each other along the axis of the adjustment rod, thereby shortening the stabilizer link. When the adjustment rod is turned in the opposite direction, the first and second rods move away from each other along the axis of the adjustment rod, thereby extending the stabilizer link. Thus, the threaded connection between the first and second rods and the adjustment rod reduces the cost of the stabilizer link. Furthermore, by turning the adjustment rod, the first and second rods can move simultaneously, significantly improving the efficiency of adjusting the length of the stabilizer link.

DETAILED DESCRIPTION

[0021] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0022] It should be noted that when a component is referred to as being "fixed to" or "disposed on" another component, it may be directly on the other component or there may be a central component. When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may be a central component at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in the specification of this application are for illustrative purposes only and do not represent the only implementation method.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of such features. Throughout the description of this application, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0024] In this application, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it can mean that the first feature is directly in contact with the second feature, or the first feature and the second feature are indirectly in contact through an intermediary.

[0025] Unless otherwise defined, all technical and scientific terms used in the specification of this application have the same meaning as commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in the specification of this application includes any and all combinations of one or more of the relevant listed items.

[0026] See also Figures 1 to 3 The present application provides a stabilizer bar link 100 for connecting a stabilizer bar 200 and a shock absorber 300. The stabilizer bar link 100 includes a first rod 10, a second rod 20 and an adjusting rod 30. One end of the first rod 10 is used to connect the stabilizer bar 200, and the other end is provided with a first threaded hole 11. One end of the second rod 20 is used to connect the shock absorber 300, and the other end is provided with a second threaded hole 21. The adjusting rod 30 has a first threaded portion 31 and a second threaded portion 32. The first threaded portion 31 is threadedly connected to the first threaded hole 11, and the second threaded portion 32 is threadedly connected to the second threaded hole 21; wherein the thread directions of the first threaded hole 11 and the second threaded hole 21 are opposite, so that when the adjusting rod 30 rotates around its own axis, the first rod 10 and the second rod 20 can move toward or away from each other along the axis of the adjusting rod 30.

[0027] It is understood that because the threads of the first threaded hole 11 and the second threaded hole 21 are in opposite directions, when the adjustment rod 30 is turned clockwise or counterclockwise, the first rod 10 and the second rod 20 move toward each other along the axis of the adjustment rod 30, thereby shortening the stabilizer link 100. When the adjustment rod 30 is turned in the opposite direction, the first rod 10 and the second rod 20 move away from each other along the axis of the adjustment rod 30, thereby extending the stabilizer link 100. In this way, the use of a threaded connection between the first rod 10, the second rod 20, and the adjustment rod 30 makes the stabilizer link 100 relatively low in cost. Moreover, by turning the adjustment rod 30, the first rod 10 and the second rod 20 can move simultaneously, thereby significantly improving the efficiency of length adjustment of the stabilizer link 100.

[0028] like Figure 2 and Figure 3 As shown, the adjusting rod 30 is further provided with a screwing portion 33, which is located between the first threaded portion 31 and the second threaded portion 32 along the axial direction of the adjusting rod 30. The screwing portion 33 is for the user to hold so as to conveniently screw the adjusting rod 30.

[0029] Optionally, the screwing portion 33 is configured as a hexagonal head. In this way, a common wrench on the market can be used to clamp the hexagonal head to screw the adjusting rod 30.

[0030] The first threaded portion 31 , the second threaded portion 32 and the screwing portion 33 are an integrated structure, which is beneficial for improving the structural strength of the adjusting rod 30 .

[0031] like Figure 2 and Figure 3 As shown, the stabilizer link 100 further includes a first locking nut 40, which is sleeved on the first threaded portion 31. The first locking nut 40 has a locked state, in which it is locked to the first threaded portion 31, and an unlocked state, in which it is movable relative to the first threaded portion 31. When the first locking nut 40 is in the locked state, it engages with the first rod 10 as a stop. It should be noted that the locking of the first locking nut 40 to the first threaded portion 31 means that the first locking nut 40 and the first threaded portion 31 cannot move relative to each other. After the stabilizer link 100 has completed length adjustment, the locked first locking nut 40 engages with the first rod 10 as a stop, preventing the first rod 10 from moving toward the adjustment rod 30 due to external forces.

[0032] like Figure 2 and Figure 3As shown, the stabilizer link 100 further includes a second locking nut 50, which is sleeved on the second threaded portion 32. The second locking nut 50 has a locked state, in which it is locked to the second threaded portion 32, and an unlocked state, in which it is movable relative to the second threaded portion 32. When the second locking nut 50 is in the locked state, it engages with the second rod 20 to form a stop. It should be noted that the second locking nut 50 being fixed to the second threaded portion 32 means that the second locking nut 50 and the second threaded portion 32 cannot move relative to each other. After the stabilizer link 100 has completed length adjustment, the locked second locking nut 50 engages with the second rod 20 to prevent the second rod 20 from moving toward the adjustment rod 30 due to external forces.

[0033] The first locking nut 40 and the second locking nut 50 are both commercially available locking nuts. Locking nuts rely on the friction between the locking nut and the bolt to achieve self-locking, thereby preventing loosening under vibration or dynamic loads. Alternatively, the first locking nut 40 and the second locking nut 50 can be configured as all-metal locking nuts, nylon locking nuts, or the like.

[0034] Specifically, the adjustment process of the stabilizer link 100 is as follows: first, loosen the first locking nut 40 and the second locking nut 50 so that the first locking nut 40 and the second locking nut 50 are both in an unlocked state; then, turn the hexagonal head clockwise or counterclockwise to adjust the length of the stabilizer link 100 to an appropriate range; finally, move the first locking nut 40 to cooperate with the stop of the first rod 10, and lock the first locking nut 40 to the first threaded portion 31. Similarly, move the second locking nut 50 to cooperate with the stop of the second rod 20, and lock the second locking nut 50 to the second threaded portion 32.

[0035] like Figure 2 As shown, the stabilizer link 100 further includes a first mounting seat 60 and a first ball pin 61. The first mounting seat 60 is fixedly connected to the end of the first rod 10 away from the first threaded hole 11. The first ball pin 61 is rotatably mounted on the first mounting seat 60 and is used to connect to the stabilizer bar 200. The first ball pin 61 is used to transmit the torque of the stabilizer bar 200 to the first mounting seat 60, thereby improving the smoothness of the vehicle's driving.

[0036] like Figure 2 As shown, the stabilizer link 100 further includes a second mounting seat 70 and a second ball pin 71. The second mounting seat 70 is fixedly connected to the end of the second rod 20 away from the second threaded hole 21. The second ball pin 71 is rotatably mounted on the second mounting seat 70 and is used to connect to the shock absorber 300. The second ball pin 71 is used to transmit the torque of the shock absorber 300 to the second mounting seat 70, thereby improving the smoothness of vehicle driving.

[0037] Please continue reading Figure 1 The present application also provides a vehicle, which includes a stabilizer bar 200, two shock absorbers 300 and two stabilizer bar links 100 as described in any one of the above embodiments. In each stabilizer bar link 100, the end of the first rod 10 away from the first threaded hole 11 is connected to the stabilizer bar 200, and the end of the second rod 20 away from the second threaded hole 21 is correspondingly connected to a shock absorber 300.

[0038] Specifically, in each stabilizer link 100 , the first ball pin 61 is connected to one end of the stabilizer bar 200 , and the second ball pin 71 is connected to one shock absorber 300 .

[0039] Furthermore, if Figure 1 As shown, along the height direction of the vehicle, the two stabilizer links 100 are connected to the stabilizer bar 200 at the same height, and the two stabilizer links 100 are connected to the corresponding shock absorbers 300 at the same height. This prevents pre-twisting of the stabilizer bar 200 before vehicle installation, thereby reducing the impact of the torsional stiffness of the stabilizer bar 200 on the wheel arch height.

[0040] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of patent protection for the present application shall be determined by the appended claims.
