Description

Technical Field

[0001] This application relates to the field of shift fork technology, and in particular to a plastic shift fork for automobiles. Background Technology

[0002] The shift fork is widely used in the accelerator pedal of a car. When the accelerator pedal is closed, one end of the shift fork acts on the screw shaft, and the other end is fixed by the stroke control groove. A closing torque is formed in a certain proportion, and the screw shaft is fixed, which means that the accelerator pedal is also fixed.

[0003] Disadvantages of existing technology:

[0004] The manufacturing of existing metal shift forks involves multiple complex and delicate processes, including but not limited to stamping, injection molding (plastic coating), punching, and riveting. These processes are intricate. Excessive cumulative errors between these processes directly impact the yield rate of the finished product. High precision requirements and stringent quality control standards are often difficult to fully achieve, leading to fluctuations in the yield rate. Ultimately, these issues result in increased product costs.

[0005] Therefore, those skilled in the art have provided an automotive plastic shift fork to solve the problems mentioned in the background art. Utility Model Content

[0006] To address the problems mentioned in the background art, this application provides an automotive plastic shift fork.

[0007] The automotive plastic shift fork provided in this application adopts the following technical solution: it includes a U-shaped fork head, a cylindrical locking pin is fixedly connected to the inner side of the U-shaped fork head, a stop block is fixedly connected to the front of the U-shaped fork head, a rigid swing arm is fixedly connected to one side of the U-shaped fork head, a flexible swing arm is fixedly connected to the other side of the rigid swing arm, a rotating shaft is fixedly connected at the connection between the rigid swing arm and the flexible swing arm, and a rivet is inserted into one side of the flexible swing arm.

[0008] Preferably, one side of the cylindrical locking pin is provided with a first reinforcing rib fixedly installed on the inner wall of the U-shaped fork head, and a second reinforcing rib is fixedly connected to the surface of the rigid swing arm, and the two ends of the second reinforcing rib are respectively connected to the U-shaped fork head and the pivot. The rigid swing arm and the pivot are integrally injection molded.

[0009] Preferably, a third reinforcing rib is fixedly connected to the groove at the connection between the rigid swing arm and the flexible swing arm to enhance the rigidity of the rigid swing arm and the flexible swing arm.

[0011] Preferably, a washer is installed between the rivet and the flexible swing arm, and the flexible swing arm is arched.

[0012] Preferably, the cylindrical pin is slidably engaged with a spiral shaft, the bottom of the spiral shaft is fixedly connected to a spiral shaft head, the rivet passes through one end of the flexible swing arm and is slidably connected to a swing plate, the swing plate has a stroke control groove inside including a locking groove and an unlocking groove, the locking groove is the locking trajectory, and the unlocking groove is the unlocking trajectory.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. By setting the user to press down the spiral shaft head, the spiral shaft head transmits force to the spiral shaft, which drives the U-shaped fork head to lift. After releasing the user, the U-shaped fork head, which is lifted by the spring inside the spiral shaft, is lifted. Because the connection between the rigid swing arm and the flexible swing arm is fixedly connected to the rotating shaft limiter, the flexible swing arm slides down naturally along the unlocking slide groove according to the lever action, thus completing the unlocking. When the front end of the spiral shaft is pressed down, the spiral shaft is pressed to the bottom, and the U-shaped fork head is pressed down. According to the lever action, the flexible swing arm lifts up and applies a lateral force to the swing plate, keeping the two in contact, thereby causing the rivet to be engaged in the groove of the locking slide groove, thus completing the locking action.

[0015] 2. The rigidity of the shift fork is increased by using a combination of a fourth reinforcing rib, a third reinforcing rib, and a second reinforcing rib.

[0016] 3. By installing rivets that are easier to rivet, the control precision of the shift fork is greatly improved, while production costs are also significantly reduced, enhancing the company's market competitiveness. Furthermore, through minor changes in design, the deformation stiffness of the shift fork is improved, compensating for material disadvantages, increasing strength, and extending service life.

[0024] The following will be combined with the appendix Figure 1-6 The technical solution of this utility model has been clearly and completely described. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] This application discloses an automotive plastic shift fork, referring to... Figure 1-6 The device includes a U-shaped fork head 1, with a cylindrical locking pin 2 fixedly connected to the inner side of the U-shaped fork head 1. A first reinforcing rib 9, fixedly installed on the inner wall of the U-shaped fork head 1, is provided on one side of the cylindrical locking pin 2 to increase the rigidity of the U-shaped fork head 1. A stop block 3 is fixedly connected to the front of the U-shaped fork head 1. A rigid swing arm 4 is fixedly connected to one side of the U-shaped fork head 1. A second reinforcing rib 10 is fixedly connected to the surface of the rigid swing arm 4, and both ends of the second reinforcing rib 10 are respectively connected to the U-shaped fork head 1 and a rotating shaft 5. A flexible swing arm 6 is fixedly connected to the other side of the rigid swing arm 4. A rotating shaft 5 is fixedly connected at the connection between the rigid swing arm 4 and the flexible swing arm 6. The rotating shaft 5 is installed in a groove in the actuator body of the screw shaft head. The upper cover of the actuator is used together to limit the rotation of the shift fork around the axis. The rigid swing arm 4 and the rotating shaft 5 are integrally injection molded. At the connection between the rigid swing arm 4 and the flexible swing arm 6, a third reinforcing rib 11 is fixedly connected in a groove to strengthen the rigidity of the rigid swing arm 4 and the flexible swing arm 6. The flexible swing arm 6 is arched in shape. A fourth reinforcing rib 12 is fixedly connected to the back of the flexible swing arm 6 near the rigid swing arm 4 to increase the rigidity of the flexible swing arm 6. A rivet 8 is inserted into one side of the flexible swing arm 6, and a washer 7 is installed between the rivet 8 and the flexible swing arm 6. The fourth reinforcing rib 12, the third reinforcing rib 11 and the second reinforcing rib 10 are used in combination to increase the rigidity of the shift fork.

[0026] By employing the aforementioned technologies and selecting the simpler riveting rivets 8 during installation, the control precision of the shift fork is greatly improved, while production costs are significantly reduced, thereby enhancing the company's market position.

[0027] In this application, a spiral shaft 13 is slidably engaged on the surface of the cylindrical pin 2, and a spring 131 is installed inside the spiral shaft 13. The spring 131 is used to lift the U-shaped fork head 1 after compression. A spiral shaft head 14 is fixedly connected to the bottom of the spiral shaft 13, and a rivet 8 is slidably connected to a swing plate 15 through one end of the flexible swing arm 6.

[0028] The interior of the tray 15 is provided with a travel control slide 151, including a locking slide 1511 and an unlocking slide 1512. The locking slide 1511 is the locking trajectory, and the interior of the locking slide 1511 is provided with a groove for placing the rivet 8. The unlocking slide 1512 is the unlocking trajectory.

[0029] Using the above technology, the user presses down the spiral shaft head 14, which then transmits the force to the spiral shaft 13. The spiral shaft 13 drives the U-shaped fork head 1 to lift up. After releasing the hand, the spring 131 inside the spiral shaft 13 lifts the U-shaped fork head 1. Because the connection between the rigid swing arm 4 and the flexible swing arm 6 is fixedly connected to the rotating shaft 5 for limiting, according to the lever action, the flexible swing arm 6 slides down naturally along the unlocking slide groove 1512 to complete the unlocking.

[0030] When locking is required, press down the front end of the spiral shaft 13 and press the spiral shaft 13 all the way down. With the U-shaped fork head 1 pressing down, according to the lever action, the flexible swing arm 6 will lift up and apply a lateral force to 1511 in the swing plate 15, so that the two are in contact, and then the rivet 8 will be inserted into the groove of the locking slide 1511 to complete the locking action.
