[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0021] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0022] A novel knob-type manual electronic throttle includes a knob 1 and a connecting rod 4. The knob 1 is typically injection molded from engineering plastic and has an internal cavity. A clamping assembly is mounted on the knob 1. The clamping assembly includes a clamping rod 9, a connecting block 11, a push rod 3, and a spring 10. The knob 1 has a clearance hole 8, in which the push rod 3 passes. One end of the clamping rod 9 is fixedly connected to the push rod 3, and the other end of the clamping rod 9 has a forked portion 5. The end of the forked portion 5 has a barb 6. The connecting rod 4 has a corresponding groove, and the connecting block is fixedly mounted on the forked portion 5. The spring 10 is fixedly connected between the forked portion 5 and the connecting block 11.
[0023] In use, press the push rod 3 to move one end of the push rod 3 away from the end of the spring 10. The spring 10 is stretched, and one end of the connecting rod 4 is inserted into the knob 1. The connecting rod 4 enters between the two forked parts 5. At this time, release the push rod 3, the spring 10 retracts, and the push rod 3 slides in the relief hole 8. The barb 6 is engaged in the groove, and the forked parts 5 surround and hug the side wall of the connecting rod 4, thereby firmly locking the knob 1 onto the connecting rod 4, realizing the power transmission between the connecting rod 4 and the knob 1. The installation steps are simple and no additional tools are required.
[0024] The outer end of the push rod 3, located outside the knob 1, has a disc-shaped pressing part 2 that protrudes approximately 3-5 millimeters from the upper surface of the knob 1. This design makes the pressing part 2 not only a physical travel limiter to prevent the push rod 3 from falling completely into the knob 1, but also a clearly visible and easily accessible operating interface. Users can easily find and press down on this protruding part with their fingers using only their sense of touch, without needing to visually confirm it.
[0025] The knob 1 has a positioning groove 7, the diameter of which matches the diameter of the connecting rod 4. When the insertion end of the connecting rod 4 is fully inserted into the knob 1, its top surface will fit precisely into and abut against the bottom wall of the positioning groove 7. This design serves as an axial limit, ensuring that each installation achieves a uniform and precise depth, thereby guaranteeing that the barb 6 can accurately align and engage with the groove.
[0026] The insertion end of the connecting rod 4 is tapered, and the insertion end of the connecting rod 4 is processed into a smooth conical surface. The slope of the conical surface allows the barb 6 to fall smoothly into the groove, greatly simplifying the installation operation. The forked part 5 has elastic deformation capability. Its root is hinged to the clamping rod 9 or forms an elastic connection point through its own flexible design, giving it excellent radial elastic deformation capability, allowing the connecting rod 4 to move more smoothly between the two forked parts 5.
[0027] The implementation principle of this embodiment is as follows: When in use, press the pressing part 2 to move one end of the push rod 3 away from the spring 10. The spring 10 is stretched, and one end of the connecting rod 4 is inserted into the knob 1. The connecting rod 4 enters between the two forked parts 5. After the insertion end of the connecting rod 4 is fully inserted into the knob 1, its top surface will just embed and abut against the bottom wall of the positioning groove 7. At this time, release the push rod 3, the spring 10 retracts, and drives the push rod 3 to slide in the relief hole 8. The barb 6 is stuck in the groove, and the forked part 5 surrounds and hugs the side wall of the connecting rod 4, thereby firmly locking the knob 1 onto the connecting rod 4 and realizing the power transmission between the connecting rod 4 and the knob 1. When disassembling, press the pressing part 2 again to make the barb 6 leave the groove, the limit of the connecting rod 4 is released, and the connecting rod 4 can be removed from the knob 1, realizing the quick disassembly and assembly of the knob 1.
