Problems solved by technology
However, since the rotation operation can be realized without effort, there is no tactile feedback to the hand when the gear is switched, and the operation feels poor
In addition, when the knob is rotated, the outer periphery of the knob cover, the upper surface and the bottom surface of the convex edge of the knob will rub against multiple components such as the knob pressure plate and the casing, and the friction sound generated is not easy to eliminate, affecting the user experience, and the wear speed is fast

Embodiment Construction
[0018] The knob, electronic equipment and engineering vehicle of the present invention will be further described in detail below in conjunction with specific embodiments and accompanying drawings.
[0019] Such as figure 1 As shown, in one embodiment, the knob 20 of the present invention is fixed on a housing 10 . The casing 10 may include an upper casing 11 and a lower casing 12, the upper casing 11 and the lower casing 12 are connected to each other to form a storage space inside, and preferably, the connection between the upper casing 11 and the lower casing 12 is sealed with a sealing strip 13 , to prevent dust or water vapor from entering the housing. A recess 14 is formed on the shell 10 , and in this embodiment, the recess 14 is formed on the upper surface of the upper shell 11 . On the bottom plate 141 of the groove 14, an upwardly protruding fixing column is formed near the edge (refer to image 3 The fixing post 143 ), the fixing post is formed with a fixing hole ...

The invention relates to a knob, electronic equipment and an engineering vehicle. The knob comprises a knob cover, a rotating shaft, a first gear component, a second gear component and a knob pressing plate. The knob pressing plate comprises a base plate with a hole formed in the middle and a side wall basically vertically extending out along the periphery of the hole. The knob cover has a sidewall extending toward the substrate. The base plate abuts against the first gear component and the boss of the rotating shaft after being fixed so as to limit movement of the first gear component and the rotating shaft in the direction parallel to the rotating shaft, and the second gear component and the first gear component can be oppositely arranged. The side wall is opposite to the rotating shaft, an elastic piece is formed on one of the first gear component and the second gear component, a plurality of protrusions are formed on the other one of the first gear component and the second gear component, and when the knob rotates, the rotating shaft drives the second gear component to rotate, so that the elastic piece collides with the protrusions one by one to prompt the gear of the knob. The knob has the advantages of being good in operation hand feeling, low in friction noise between the rotating shaft and the knob pressing plate and good in use feeling.
Description
technical field [0001] The invention relates to a knob, an electronic device using the knob and an engineering vehicle. Background technique [0002] The rear control panel of an ordinary cement mixer truck controls the amount of cement in and out and the rotation speed of the tank are all mechanical handles, which are realized by using a potentiometer or a dial switch and setting a rotating rod in the hole through a sleeve cap. It has a large mechanical size. , takes up a lot of space, and cannot stay in a certain position. The Chinese utility model patent CN202120103846.3 with an application date of January 15, 2021 and a publication date of September 28, 2021 discloses a waterproof knob for the rear control panel of a cement mixer truck, which uses magnetic field induction to realize the function of the knob switch , The structure is simple, compact, and the advantages of labor-saving operation. However, since the rotation operation can be realized without effort, there...
