Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted multimedia equipment, in particular to a vehicle-mounted multimedia player component. Background Art

[0002] With the development of flat-panel display technology and touch screen technology, more and more in-vehicle multimedia devices are using large touch screens, which largely replace physical buttons through touch, allowing users to operate directly on the screen to enhance user experience.

[0003] After adopting touch screens on in-vehicle multimedia devices, car manufacturers have greatly reduced the use of physical buttons or knobs. Some car manufacturers have even cancelled all physical buttons. Although this setting looks high-end, it is actually not conducive to vehicle control. For example, when the display is navigating, when you need to adjust the audio volume or the air-conditioning temperature, you need to exit the current display before you can operate. This operation procedure is cumbersome and has great potential risks.

[0004] In order to solve the problem of combining physical buttons with display screens, a patent document with announcement number CN208142076U discloses a novel knob button structure combined with a display screen, including a display panel, a cylindrical knob bracket and a knob assembly sleeved outside the knob bracket, wherein the knob bracket is arranged on the display area of ​​the display panel, and a positioning structure passing through the display panel is provided at the bottom end of the knob bracket; a button assembly is provided in the knob bracket, and the button assembly includes a pressing portion, a circular pressing bracket and a touch switch; the touch switch is fixedly installed in the knob bracket, the pressing portion includes a pressing surface and a pressing block connected to the pressing surface, and the pressing bracket is provided with a switch groove for sleeved the touch switch and a pressing groove cooperating with the pressing block. This scheme provides a structure for combining the knob button structure with the display screen, which can simplify the operation procedure and facilitate operation.

[0005] The solution describes that the positioning mechanism behind the knob bracket passes through the display panel and is fixed to the display panel by screws. Correspondingly, the display panel is provided with screw holes that cooperate with the screws. This setting does not design a positioning structure for the rotating bracket, which may cause the rotating bracket to deviate during installation, causing the rotating bracket to cover the content to be displayed; in addition, it can be seen from the description and drawings of the patent document that this solution will cover the display area of ​​a larger display, affecting its use; in addition, since the knob needs to control the volume or air conditioning settings, wires are indispensable between the knob and the control panel, and there is no wiring design in this solution, so it is necessary to design a vehicle-mounted multimedia player component to solve the above problems.

[0034] A housing mounting post 143 is also provided on the outer side of the bottom of the cavity 14 , and the housing mounting post 143 is used to connect the housing to the dashboard of the car.

[0035] In this embodiment, the housing is made of alloy casting, but the housing can also be made of plastic injection molding.

[0036] The cavity 14 can increase the heat dissipation space and the heat dissipation area of ​​the housing; the heat dissipation holes 141 can facilitate the installation of the radiator and further improve the heat dissipation efficiency.

[0037] like Figure 2 and Figure 7 As shown, a knob mounting portion 15 is further provided at the lower front side of the shell body 1, and the knob mounting portion 15 extends outward beyond the display mounting portion 11. The cross-section of the knob mounting portion 15 is an arc shape, that is, the knob mounting portion 15 exceeds the original rectangular display mounting portion 11, so that the knob 2 will not block a large area of ​​the effective display area of ​​the display mounting portion 11.

[0038] In this embodiment, there are two knob mounting parts 15, which are respectively located at the lower left corner and the lower right corner of the shell body 1.
