Description

Technical Field

[0001] The utility model relates to a vehicle-mounted display device, more specifically, to a vehicle-mounted central control button component with a screen. Background Art

[0002] Usually, the rotary buttons of car display devices, such as air-conditioning control knobs, are generally placed on the edge of the display screen, such as on the left, right or bottom of the display screen. This design is not an integrated design, which greatly limits the usable size of the screen and also appears to be of low grade.

[0003] Chinese utility model patent document CN208848790U discloses a vehicle-mounted button, including a pressing plate, a light-shielding perimeter bone and a guide bone; the pressing plate has a pressing surface and a bottom surface facing each other; the light-shielding perimeter bone is arranged on the bottom surface, and the light-shielding perimeter bone is vertically arranged around the edge of the bottom surface to form a columnar structure with a accommodating cavity; the light-shielding perimeter bone is provided with a limiting hole for limiting the travel range of the vehicle-mounted button; the guide bone is vertically arranged on the inner side wall of the light-shielding perimeter bone, and the guide bone is an elongated strip structure as a whole, and the guide bone and the light-shielding perimeter bone cooperate to form a T-shaped downward pressing structure for pressing the function keys on the panel body. The light-shielding perimeter bone is formed by a first light-shielding perimeter bone, a second light-shielding perimeter bone, a third light-shielding perimeter bone and a fourth light-shielding perimeter bone. The first light-shielding perimeter bone and the third light-shielding perimeter bone are arranged opposite to each other, and the second light-shielding perimeter bone and the fourth light-shielding perimeter bone are arranged opposite to each other; the guiding bone includes a first guiding bone, a second guiding bone, a third guiding bone and a fourth guiding bone. The first guiding bone is arranged on the inner wall of the first light-shielding perimeter bone and is close to the fourth light-shielding perimeter bone. The second guiding bone is arranged on the inner wall of the second light-shielding perimeter bone and is close to the third light-shielding perimeter bone. The third guiding bone is arranged on the inner wall of the third light-shielding perimeter bone and is close to the second light-shielding perimeter bone. The fourth guiding bone is arranged on the inner wall of the fourth light-shielding perimeter bone and is close to the first light-shielding perimeter bone. The second light-shielding circumference bone and the fourth light-shielding circumference bone have the same height. The T-shaped downward pressing structure formed by the cooperation of the first guide bone and the first light-shielding circumference bone has a top pressing portion protruding from the second light-shielding circumference bone; the T-shaped downward pressing structure formed by the cooperation of the third guide bone and the third light-shielding circumference bone has a top pressing portion protruding from the second light-shielding circumference bone. There are two limiting holes, which are respectively arranged in the middle area of ​​the first light-shielding circumference bone and the third light-shielding circumference bone. The light-shielding circumference bone is also provided with an avoidance gap which is an overall long strip. The avoidance gap is arranged on the first light-shielding circumference bone, and the avoidance gap is opposite to the third guide bone. The pressing plate is a translucent plate; the area on the bottom surface surrounded by the light-shielding circumference bone is a laser engraving area for laser engraving characters. The panel body is provided with a function key slot and a function key, the function key is arranged in the function key slot, and a limit block is arranged in the function key slot; the vehicle-mounted button is installed in the function key slot and abuts against the function key, and the limit portion of the limit block is placed in the limit hole. The function key is covered with a silica gel button, and the vehicle-mounted button abuts against the silica gel button.

[0004] Obviously, the car button of the patent maximizes the laser engraving area on the bottom surface by combining the traditional shading frame and the guide frame into one and setting them vertically around the edge of the bottom surface, making the structure of the entire button more concise, and significantly reducing the processing mold and material costs. In addition, the car button can be processed according to the shape and size requirements of the function key slot as needed, especially the processing of smaller car buttons, which has a wider range of applications; at the same time, the height of the shading frame (set according to the depth of the function key slot on the panel body) can also be set to the maximum to improve the shading effect. This structure cannot solve the problem that the existing knob screen lacks a sense of integrity. Utility Model Content
