In addition, the terms "first", "second", "third" and the like are only used to distinguish descriptions, and cannot be understood as indicating or implying relative importance. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined. The meaning of "several" is one or more, unless otherwise clearly and specifically defined.

[0030] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below through the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the scope of the utility model. In addition, in the following description, the description of the known structure and technology is omitted to avoid unnecessary confusion of the concept of the utility model.

[0032] Example 1: See Figure 1 and Figure 2A vehicle linkage rocker includes a frame 1, a rocker 2, a shock absorber 3 and a roller 4. The frame 1 is provided with more than two rockers 2, and the frame 1 is provided with more than two linkage components 5. Each rocker 2 is arranged on the frame 1 longitudinally (that is, in the length direction of the frame 1 or the front-to-back direction). The linkage component 5 is rotatably connected to the frame 1. A shock absorber 3 is arranged between adjacent linkage components 5. The rocker 2 and the linkage component 5 are connected by a rotatable push-pull member 6. This arrangement will cause the linkage component 5 and the shock absorber 3 to move when the roller 3 contacts a rough road. The linkage component 5 and the shock absorber 3 will make the frame 1 more stable, thereby improving the safety of use. The linkage component 5 can realize simultaneous movement in opposite directions or in opposite directions or move to one side separately according to the rough road, which is conducive to satisfying the overall stability for the rough road and improving the safety of use.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, in this embodiment, two rocker arms 2 are used, and the two rocker arms 2 are distributed correspondingly to each other, and two linkage components 5 are also used, and the two linkage components 5 are also distributed correspondingly to each other. This arrangement is reasonable and easy to implement. Further, a linkage component 5 can be added on the basis of the two linkage components 5, and the adjacent linkage components 5 (in the width direction) are connected by the shock absorber 3. This is more conducive to the linkage components 5 to achieve simultaneous movement in the same direction or in the opposite direction or to one side separately according to the rough road, which is conducive to satisfying the overall stability for the rough road and improving the safety of use.

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the frame 1 can be a part of the scooter or a separate component, so it has various forms and a wide range of options, which is more conducive to meeting the use requirements. The frame 1 is regarded as the body structure except the suspension and wheels, and the frame is regarded as fixed at any position of the frame 1.

[0035] Embodiment 2: It can be explained on the basis of embodiment 1, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the frame 1 is provided with a mounting member 7 for mounting the corresponding rocker arm 2. The mounting member 7 enables the rocker arm 2 to be disposed on the frame 1 longitudinally (i.e., in the length direction or front-to-back direction of the frame 1), and the rocker arm 2 moves up and down with the mounting member 7 as a fulcrum.

[0036] Further, if Figure 5 and Figure 6 As shown, the mounting member 7 includes a mounting seat 71 arranged on the frame 1, a connecting shaft 72 is arranged on the mounting seat 71, a rocker arm 2 is arranged on the connecting shaft 72, and a connecting plate 73 is also arranged on the connecting shaft 72. The connecting plate 73 is fixedly connected to the rocker arm 2, which is conducive to the connecting plate 73 swinging together with the up and down swinging of the rocker arm 2. A rotatable push-pull member 6 is arranged on the connecting plate 73, and a linkage assembly 5 is arranged on the rotatable push-pull member 6. Adjacent linkage assemblies 5 are connected by shock absorbers 3. The up and down swinging of this connecting plate 73 drives the horizontal back and forth movement of the rotatable push-pull member 6. The horizontal movement of the rotatable push-pull member 6 will cause the linkage assembly 5 to move toward or oppositely at the same time or to one side separately. This is conducive to satisfying the overall stability for rugged roads and improving the safety of use.

[0037] To further illustrate, Figure 3 and Figure 5 As shown, the connecting plate 73 and the rocker arm 2 are fixed together by bolts. In the present embodiment, a plurality of fixing members are evenly spaced around the connecting shaft 72. The connecting plate 72 and the rocker arm 2 are connected together by fixing members, and the fixing members are bolts, specifically four bolts, which is conducive to making the connection between the connecting plate 73 and the rocker arm 2 more stable.

[0038] To further illustrate, Figure 3 As shown, at least one sealing ring 74 is provided between the connecting shaft 72 and the rocker arm 2, which is beneficial to improving the stability of the connection between the connecting shaft 72 and the rocker arm 2. In this embodiment, two sealing rings 74 are used.

[0039] To further illustrate, Figure 3 and Figure 5 As shown, an outer cover 75 is provided on the outer side wall end surface of the connecting shaft 72, and a screw 76 is provided on the end surface of the connecting shaft 72, and the outer cover 75 can be fixed to the outer side wall end surface of the connecting shaft 72 by the screw 76. The screw 76 can be replaced by a bolt or other components for easy implementation.

[0040] Embodiment 3: It can be explained on the basis of embodiment 2, such as Figure 1 and Figure 6As shown, the rotatable push-pull member 6 adopts a rod end joint bearing or a ball head pull rod, which is not limited to the rod end joint bearing or the ball head pull rod, and can also be an intermediate rod, one end of the intermediate rod is used to connect to the connecting plate 73 of the mounting member 7, and the other end of the intermediate rod is used to connect to the linkage assembly 5. It can be seen that there are various forms and a large room for selection. In this embodiment, the two ends of the rotatable push-pull member 6 are respectively provided with connecting bolts, so that the connecting plate 73 is connected to the connecting bolt at one end of the rotatable push-pull member 6, and the linkage assembly 5 is connected to the connecting bolt at the other end of the rotatable push-pull member 6. This is not only simple to set up and easy to implement, but also conducive to better realizing the horizontal movement of the rotatable push-pull member 6.

[0041] Embodiment 4: It can be described on the basis of Embodiment 1, Embodiment 2 or Embodiment 3, such as Figure 3 , Figure 4 and Figure 6 As shown, the linkage assembly 5 includes a fixed seat 51 arranged on the frame 1, the number of which is consistent with that of the rotatable push-pull members 6, and a linkage member 52 is movably arranged on the fixed seat 51, one end of the linkage member 52 is arranged on the rotatable push-pull member 6, and the other end of the linkage member 52 is arranged on the shock absorber 3, and the corresponding linkage members 52 are respectively connected through the two ends of the shock absorber 3. It is further explained that the fixed seat 51 and the linkage member 52 are connected through a movable shaft 53, which is conducive to the linkage member 52 rotating back and forth with the movable shaft 53 as a fulcrum, and it is further explained that each linkage member 52 includes an upper member 521 and a lower member 522, the upper member 521 and the lower member 522 are connected through the movable shaft 53, and the upper member 521 and the lower member 522 are locked and connected together by a plurality of fixing bolts. Finally, I would like to explain that the linkage member 52 is divided into a crossbar portion and a vertical bar portion integrally formed with the crossbar portion. This arrangement will enable one end of the linkage member 52 connected to the shock absorber 3 to rotate with the movable shaft 53 as a fulcrum, thereby causing the linkage member 52 to move toward or oppositely at the same time or to one side separately, and one end of the linkage member 52 connected to the rotatable push-pull member 6 rotates with the movable shaft 53 as a fulcrum, so that the linkage member 52 will prompt the rotatable push-pull member 6 to move horizontally, which is ultimately conducive to meeting the overall stability for rugged roads and improving the safety of use.

[0042] The vehicle-use linkage rocker arm of the utility model can be used not only in scooters, but also in other similar device settings, and has a wider application.

[0043] The standard parts used in this application document can all be purchased from the market, and the specific connection methods of each part adopt conventional means such as mature bolts and rivets in the prior art, which will not be described in detail here.

[0044] It should be noted that although the above embodiments have been described in this article, this does not limit the scope of patent protection of the utility model. Therefore, based on the innovative concept of the utility model, changes and modifications to the embodiments described in this article, or equivalent structural or equivalent process changes made using the contents of the utility model specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields are all included in the scope of protection of the utility model patent.
