Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted display screens, in particular to a vehicle-mounted display screen back plate and a vehicle-mounted display screen. Background Art

[0002] A vehicle-mounted display screen is usually provided with a back panel, and a receiving cavity is opened on the front side of the back panel, and an optical component is installed in the receiving cavity. Since it is necessary to consider the installation and fixation of the vehicle-mounted display screen, a threaded through hole is opened on the back side of the vehicle-mounted display screen back panel, and screws are installed for installing and fixing the back panel. Since the friction between the screws and the back panel will generate debris when the screws are installed, dust-proof tape is set in the receiving cavity to block the threaded through hole. However, when installing the screws, since the threaded through hole is already blocked, as the screws are screwed in, the air in the threaded through hole is compressed, and the compressed air will cause the dust-proof tape to bulge. The bulged dust-proof tape presses the backlight panel for a long time, causing white spots to form in the display area, affecting the viewing experience. To solve this problem, some back panels replace the threaded through holes with threaded blind holes. However, the debris generated when opening the threaded blind holes is easily accumulated on the thread teeth and the bottom of the threaded blind holes, which is difficult to clean. Therefore, a new technical solution is needed to solve the problem of the bulging dust-proof tape pressing the backlight panel for a long time, causing white spots to form in the display area, affecting the viewing experience. Utility Model Content

[0003] The main purpose of the utility model is to provide a vehicle-mounted display screen back panel and a vehicle-mounted display screen, which are designed to prevent the air in the threaded through hole from being compressed and squeezing the backlight panel, so as to solve the problem in the prior art that as the screw is screwed in, the air in the threaded through hole is compressed, and the compressed air causes the dustproof tape to bulge. The bulged dustproof tape squeezes the backlight panel for a long time, causing white spots to form in the display area, affecting the viewing experience.

[0026] The utility model provides a vehicle-mounted display screen back plate and a vehicle-mounted display screen.

[0027] See also Figure 1-Figure 4 The back panel of the vehicle-mounted display screen is applied to the vehicle-mounted display screen, including a back panel 1, a side surface of the back panel 1 in the thickness direction of which is provided with a receiving cavity 101 for installing an optical component, a side surface of the back panel 1 in which the receiving cavity 101 is provided with a receiving groove 102, and the depth direction of the receiving groove 102 is consistent with the depth direction of the receiving cavity 101; the back panel 1 is provided with a threaded through hole 103 in the receiving groove 102, the back panel 1 is provided with an exhaust channel 104 and an exhaust hole 105, and the exhaust outlet of the exhaust hole 105 is provided on a side surface of the back panel 1 away from the receiving groove 102; an end of the threaded through hole 103 close to the receiving groove 102 is connected to the exhaust hole 105 through the exhaust channel 104; an adhesive component 2, the adhesive component 2 is provided in the receiving groove 102 and covers the threaded through hole 103.

[0028] The utility model provides a vehicle-mounted display screen back panel by opening a threaded through hole 103 and setting an adhesive component 2 at the threaded through hole 103 to cover the threaded through hole 103. After the threaded through hole 103 is opened, an air gun can be used to aim at the threaded through hole 103, and high-pressure gas enters from one end of the threaded through hole 103 and is discharged from the other end to blow out the debris in the threaded through hole 103 to prevent the debris from accumulating inside the threaded through hole 103. After cleaning, the adhesive component 2 is used to cover the threaded through hole 103 to prevent the debris generated by the friction between the screw and the back panel from entering the accommodating cavity 101 when the screw is installed. An exhaust channel 104 and an exhaust hole 105 are additionally provided, and the exhaust channel 104 is connected to the threaded through hole 103, and the exhaust hole 105 is connected to the exhaust channel 104. During the installation of the screws, the gas in the threaded through hole 103 will enter the exhaust channel 104 and be discharged from the exhaust hole 105. The air in the threaded through hole 103 will not be compressed, causing the adhesive component 2 to bulge. This solves the problem in the prior art that as the screw is screwed in, the air in the threaded through hole 103 is compressed, and the compressed air causes the dustproof tape to bulge. The bulged dustproof tape squeezes the backlight panel for a long time, causing white spots to form in the display area, affecting the viewing experience.

[0029] See also Figure 3 and Figure 4 In one embodiment of the present invention, a groove is opened in the accommodating groove 102 to form an exhaust channel 104, and the adhesive component 2 also covers the notch of the groove.

[0030] In the technical solution of this embodiment, the exhaust channel in the form of a groove is arranged in the receiving groove 102, which is relatively convenient to process. The use of the adhesive component 2 to cover the notch of the groove can prevent debris generated when installing the screw from entering the groove through the threaded through hole 103 and entering the receiving cavity 101 through the groove. In addition, a hole can also be drilled at one end of the threaded through hole 103 close to the receiving groove 102 to form an exhaust channel 104. One end of the hole is connected to the threaded through hole 103, and the other end is connected to the exhaust hole 105. The form of the exhaust channel 104 can be selected according to actual usage.

[0031] See also Figure 4 In one embodiment of the present invention, the exhaust hole 105 is a through hole, the exhaust hole 105 is connected to the receiving groove 102 and the exhaust groove 104, and the adhesive component 2 also covers the exhaust hole 105.

[0032] In the technical solution of this embodiment, whether the exhaust hole 105 is connected to the exhaust channel 104 can be confirmed by direct observation. At the same time, the exhaust hole 105 is set as a through hole. An air gun can be used to aim at the exhaust hole 105. High-pressure gas enters from one end of the exhaust hole 105 and is discharged from the other end, blowing out the debris generated by the opening of the exhaust hole 105 to prevent the debris from accumulating inside the exhaust hole 105.

[0033] See also Figure 4 In one embodiment of the present invention, a filler is provided in the exhaust hole 105 , and the filler is a sponge, and the filler is bonded and fixed to the adhesive component 2 .

[0034] In the technical solution of this embodiment, after the screws are installed, filler is filled into the exhaust hole 105, and the exhaust hole 105 is blocked with the filler. While ensuring air permeability, dust can be effectively prevented from entering the exhaust hole 105. The filler is adhered by the adhesive component 2 to prevent the filler from falling off.

[0035] See also Figure 4 In one embodiment of the present invention, the width of the exhaust channel 104 is 1-2 mm.

[0036] In the technical solution of this embodiment, the exhaust channel 104 is only used to discharge the gas in the threaded hole 103, so it does not need to be set too large. An overly large exhaust channel 104 takes a long time to process, while a smaller exhaust channel 104 requires higher processing precision. An exhaust channel 104 with a width of 1-2 mm is more reasonable, takes a short processing time, and does not need to have particularly high processing precision.

[0037] See also Figure 2 In one embodiment of the present invention, the thickness of the adhesive component 2 does not exceed the depth of the receiving groove 102.

[0038] In the technical solution of this embodiment, the thickness of the adhesive component 2 does not exceed the depth of the receiving groove 102, which can effectively reduce the impact of the adhesive component 2 on the backlight panel.

[0039] See also Figure 2 In one embodiment of the present invention, the adhesive component 2 is a dustproof tape or foam adhesive.

[0040] In the technical solution of this embodiment, a sticky article with high viscosity, such as dustproof tape or foam glue, is used to stick it in the receiving groove 102 to prevent the sticking component 2 from falling off.

[0041] The present invention also provides a vehicle-mounted display screen, including the above-mentioned vehicle-mounted display screen back panel. The specific structure of the vehicle-mounted display screen refers to the above-mentioned embodiment. Since the vehicle-mounted display screen adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0042] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
