Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically a control arm that is easy to install. Background Technology

[0002] A control arm is a key transmission and guiding component in a mechanical system used to connect fixed and moving parts and to precisely control the trajectory and attitude of the moving parts. Easy-to-install control arms are mainly used in everyday automobile manufacturing, high-performance automobiles, and automobile modification.

[0003] In the existing technology, the use of the ball bearing and the limiting groove on the inner side of the shock absorber assembly connection end improves the ease of installation. However, during use, due to the weight of the control arm itself, multiple people are required to cooperate in the installation, which leads to the problem of consuming a lot of manpower. Therefore, in order to solve the above problems, a control arm that is easy to install is proposed. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a control arm that is easy to install.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: a control arm that is easy to install, comprising a control arm body, a fixing plate fixedly connected to the inner wall of the control arm body, a limit rod fixedly connected to the inner wall of the fixing plate, both ends of the limit rod fixedly connected to the inner wall of the control arm body, a sliding plate slidably connected to the outer wall of the limit rod, the outer wall of the sliding plate slidably connected to the inner wall of the control arm body, a spring provided on the outer wall of the sliding plate, the outer wall of the spring being provided on the outer wall of the fixing plate, a locking tooth one fixedly connected to the outer wall of the locking tooth one engaging with the outer wall of the locking tooth two, a shock absorber assembly fixedly connected to the outer wall of the locking tooth two, the outer wall of the shock absorber assembly slidably connected to the outer wall of the control arm body, the inner wall of the shock absorber assembly slidably connected to the outer wall of the locking tooth one, and a connecting component provided on the inner wall of the shock absorber assembly.

[0006] Preferably, the connecting assembly includes a washer, the outer wall of which is slidably connected to the inner wall of the shock absorber assembly, the outer wall of which is slidably connected to the outer wall of the second retaining tooth, a bolt slidably connected to the inner wall of the washer, the outer wall of which is slidably connected to the inner wall of the fixing plate, the outer wall of which is slidably connected to the inner wall of the sliding plate, the outer wall of which is slidably connected to the inner wall of the first retaining tooth, and a nut threadedly connected to the outer wall of the bolt, the outer wall of which is slidably connected to the outer wall of the washer.

[0007] Preferably, the outer wall of the control arm body is fixedly connected to a housing, the inner wall of the housing is rotatably connected to a rotating rod, and the outer wall of the rotating rod is fixedly connected to a knob.

[0008] Preferably, the outer wall of the rotating rod is rotatably connected to a rotating plate, and the outer wall of the rotating plate is provided with locking teeth.

[0009] Preferably, the teeth of the locking teeth are engaged with a ratchet, the inner wall of the ratchet is fixedly connected to the outer wall of the rotating rod, and the rear outer wall of the ratchet is slidably connected to the outer wall of the housing.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0023] This application discloses a control arm that is easy to install. (See also...) Figure 2 and Figure 3A control arm that is easy to install includes a control arm body 1. A fixing plate 2 is fixedly connected to the inner wall of the control arm body 1. A limit rod 3 is fixedly connected to the inner wall of the fixing plate 2. Both ends of the limit rod 3 are fixedly connected to the inner wall of the control arm body 1. A sliding plate 4 is slidably connected to the outer wall of the limit rod 3. The outer wall of the sliding plate 4 is slidably connected to the inner wall of the control arm body 1. A spring 5 is provided on the outer wall of the sliding plate 4. The outer wall of the spring 5 is provided on the outer wall of the fixing plate 2. A locking tooth 6 is fixedly connected to the outer wall of the sliding plate 4. A locking tooth 7 is engaged with the outer wall of the locking tooth 6. A shock absorber assembly 8 is fixedly connected to the outer wall of the locking tooth 7. The outer wall of the shock absorber assembly 8 is slidably connected to the control arm body 1. The outer wall of the body 1 and the inner wall of the shock absorber assembly 8 are slidably connected to the outer wall of the first tooth 6. The inner wall of the shock absorber assembly 8 is provided with a connecting component. By pressing the first tooth 6 inward, the sliding plate 4 is pushed to slide on the outer wall of the limit rod 3. During the movement, the spring 5 will undergo elastic deformation, which can provide power for the return of the first tooth 6. After the control arm body 1 is placed in the designated position, releasing the first tooth 6 will allow it to rebound and come into contact with the second tooth 7 provided in the shock absorber assembly 8. Thus, while initially fixing the control arm, the first tooth 6 can be pressed to separate it from the second tooth 7, thereby switching different angles. Therefore, the installation of the control arm can be completed by a single person.

[0024] Reference Figure 1 and Figure 4 The connecting components include a washer 9, the outer wall of which is slidably connected to the inner wall of the shock absorber assembly 8, the outer wall of which is slidably connected to the outer wall of the second tooth 7, a bolt 10 slidably connected to the inner wall of the washer 9, the outer wall of which is slidably connected to the inner wall of the fixing plate 2, the outer wall of which is slidably connected to the inner wall of the sliding plate 4, and the outer wall of which is slidably connected to the inner wall of the first tooth 6. A nut 11 is threadedly connected to the outer wall of the bolt 10, and the outer wall of the nut 11 is slidably connected to the outer wall of the washer 9. By inserting the bolt 10 into the hole of the control arm body 1 and setting the washer 9 on the outer side of the second tooth 7 on both sides, the bolt 10 and the nut 11 can push the washer 9 to move the first tooth 6 inward while achieving fixation, thereby separating the first tooth 6 from the second tooth 7, so as not to affect the normal use of the control arm body 1.

[0025] Reference Figure 1 and Figure 5 The outer wall of the control arm body 1 is fixedly connected to the outer shell 12, and the inner wall of the outer shell 12 is rotatably connected to the rotating rod 13. The outer wall of the rotating rod 13 is fixedly connected to the knob 14. The rotating rod 13 is provided on the inner wall of the outer shell 12 to provide power transmission for rotating the knob 14 to make the gear 18 and ratchet 17 rotate.

[0026] Reference Figure 1 and Figure 5The outer wall of the rotating rod 13 is rotatably connected to a rotating plate 15. The outer wall of the rotating plate 15 is provided with locking teeth 16. The rotating plate 15 and the locking teeth 16 can lock the ratchet 17, achieving self-locking. At the same time, the rotating plate 15 can be turned to make the locking teeth 16 disengage from the ratchet 17, thereby achieving unlocking.

[0027] Reference Figure 1 and Figure 5 The locking teeth 16 are engaged with a ratchet 17. The inner wall of the ratchet 17 is fixedly connected to the outer wall of the rotating rod 13, and the rear outer wall of the ratchet 17 is slidably connected to the outer wall of the housing 12. By setting the ratchet 17, the rotation of the rotating rod 13 can be restricted, thereby realizing the self-locking of the telescopic rod 20.

[0028] Reference Figure 1 and Figure 5 A gear 18 is fixedly connected to the outer wall of the rotating rod 13. The tooth end of the gear 18 is meshed with a rack 19. The gear 18 can rotate under the drive of the rotating rod 13 and can move synchronously with the rack 19 it meshes with.

[0029] Reference Figure 1 and Figure 5 A telescopic rod 20 is fixedly connected to the lower surface of the rack 19. The outer wall of the telescopic rod 20 is slidably connected to the inner wall of the housing 12. The rack 19, which meshes with the gear 18, can drive the telescopic rod 20 to move on the inner wall of the housing 12, thereby controlling the length of the control arm.

[0030] Working principle: When the control arm is needed, pressing the first tooth 6 inward pushes the sliding plate 4 to slide against the outer wall of the limit rod 3. During this movement, the spring 5 undergoes elastic deformation, providing power for the return of the first tooth 6. After placing the control arm body 1 in the designated position, releasing the first tooth 6 allows it to spring back and contact the second tooth 7 located within the shock absorber assembly 8. This initially secures the control arm, and pressing the first tooth 6 further separates it from the second tooth 7, allowing for different angle adjustments. Thus, the control arm can be installed by a single person. Bolts 10 are inserted into the holes in the control arm body 1, and washers 9 are placed on the outer sides of the second teeth 7 on both sides, ensuring secure installation. Press the locking tooth 6 to move it inward, thereby separating the locking tooth 6 from the locking tooth 7, so as not to affect the normal use of the control arm body 1. After connecting one end of the control arm, turn the knob 14 to drive the rotating rod 13 to rotate according to the required length, so that the gear 18 rotates at the same time. The rack 19 meshing with the gear 18 can drive the telescopic rod 20 to move on the inner wall of the outer shell 12, thereby controlling the length of the control arm. While the rotating rod 13 rotates, the ratchet 17 can rotate at the same time, and achieve self-locking under the combined action of the rotating plate 15 and the locking tooth 16, thereby preventing the control arm from retracting. This control arm can solve the problem of excessive manpower input, and at the same time improve the applicability and installation sensitivity of the control arm.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
