DETAILED DESCRIPTION

[0021] For the display screen installed in the center control position of the vehicle, the simplicity and beauty of its appearance and structure play an important role in enhancing the design sense of the vehicle. However, the display screen needs to have a photosensitivity adjustment function to meet its smooth use needs. Currently, the light-sensitive area of ​​the display screen is mostly set at the edge of the display area, which will cause the side frame structure to be complicated or the width to increase, which is contrary to the simple design structure of the narrow-frame display screen.

[0022] In order to make the technical personnel in this field better understand the present invention, the embodiments of the present invention are described below with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the contents of the utility model described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to those necessary for the solutions of the utility model described in the claims.

[0023] See also Figure 1-3The display screen provided by the embodiment of the utility model mainly includes an upper shell 10, a lower shell 20, a light sensing element 30 and a printed circuit board 40, wherein the upper shell 10 and the lower shell 20 are connected and contacted by a buckling structure to form a cavity structure of the accommodating cavity. Preferably, the upper shell 10 and the lower shell 20 are buckled by a concave-convex structure and the outer walls of the upper shell 10 and the lower shell 20 after connection are fitted to form an outer wall surface of an integrated structure to maintain good sealing and appearance integrity; and the printed circuit board 40 is arranged in the accommodating cavity to be enclosed and protected by the upper shell 10 and the lower shell 20 to avoid the influence of external dust pollutants, etc. The printed circuit board 40 operates smoothly; the light sensing element 30 is electrically connected to the printed circuit board 40 to feedback the light signal to the printed circuit board 40, and the feedback printed circuit board 40 adjusts the display brightness of the display screen, so that the information on the display screen can be clearly observed. It should be noted that the electrical connection between the light sensing element 30 and the printed circuit board 40 is a communication connection, and the printed circuit board 40 adjusts the display brightness of the display screen after receiving the feedback from the light sensing element 30, which is the same as the feedback and adjustment process in the prior art. The focus of this article is on the setting position and structure of the light sensing element 30, and the feedback and adjustment process will not be repeated here.

[0024] On the basis of the above structure, the upper shell 10 is also provided with a mounting groove structure to fill and embed a light guide column 50 for transmitting light. It should be noted that the filling setting of the light guide column 50 is intended not to destroy the outer frame structure of the upper shell 10. The setting of the light guide column 50 can transmit the light of the external environment to the desired position. Therefore, the light sensing element 30 can sense the external light with the help of the light guide column 50 and can be set at any position in the display screen. Similarly, the setting of the light guide column 50 makes it unnecessary for the display screen to set a photosensitive area on the side of the display area, which causes the problem of increased frame. Specifically, the light guide column 50 includes a first light guide surface 510 and a second light guide surface 520, wherein the first light guide surface 510 is set toward the outside of the display screen, so that the light of the external environment enters the interior of the light guide column 50 through the first light guide surface 510, and reaches the position of the second light guide surface 520 after being refracted inside the light guide column 50. , so as to pass through the light guide column 50 from the position of the second light guide surface 520, so the sensing area of ​​the light sensing element 30 is set toward the second light guide surface 520 to meet the perception of the external lighting state; the material of the light guide column 50 is a material with good light conduction efficiency, such as polycarbonate, acrylic resin or epoxy resin, which not only ensures the efficient transmission of light, but also has excellent weather resistance and mechanical strength, and ensures that it has sufficient structural strength and service life while being exposed to the external environment on the upper shell 10. Based on the above structure, the light sensing element 30 does not need to be set toward the open hole and light-transmitting area as in the prior art, but can be set at any suitable position in the display screen. Suitable for placement here specifically refers to an area inside the display screen that does not affect the arrangement of other components and does not adversely affect the appearance, such as the width of the frame, and the light sensing element 30 senses the external ambient light with the help of the light guiding effect of the light guide column 50.

[0025] The display screen provided by the embodiment of the utility model has a groove body on the frame structure of the upper shell 10 to embed and install a light guide column 50. The light guide column 50 allows light to enter through its first light guide surface 510 facing the outside of the display screen, and transmits the light through the second light guide surface 520 after internal refraction. The embedded structure of the light guide column 50 makes the appearance structure of the upper shell 10 unchanged, that is, the width and thickness of the upper shell 10 will not change, and at the same time, the light of the external environment is transmitted to the inside of the display screen. The light sensing element 30 can be set at any position in the display screen in a posture facing the second light guide surface 520 to receive the light of the external environment and feedback the printed circuit board 40 electrically connected thereto to adjust the brightness of the display screen in real time. The above-mentioned display screen can realize the self-adjustment function of brightness through the cooperation of the light guide column 50, the light sensing element 30 and the printed circuit board 40. At the same time, the embedded setting of the light guide column 50 makes it unnecessary to set a photosensitive area in the display area of ​​the display screen, and there will be no problem of occupying the frame, thereby realizing a simple and beautiful design of the display screen.

[0026] Furthermore, in the display screen provided in the embodiment of the utility model, the display module for displaying images is tightly combined with the upper shell 10 by means of an adhesive connection to maintain the stability of the structure and simplify the assembly process of the display screen. At the same time, in some embodiments of the utility model, the display module is composed of a screen 60 and a cover plate 70. The cover plate 70 is made of glass to protect the screen 60 from physical damage without affecting the experience of the screen 60. The adhesive area is arranged on the cover plate 70 so that the cover plate 70 and the upper shell 10 cooperate to enclose the screen 60 to prevent dust and moisture from invading the screen 60.

[0027] On the basis of the above structure, the light sensing element 30 is arranged perpendicular to the display module so as to occupy a smaller space in the width direction of the display module and can be stacked with the adhesive area on the display module. It should be noted that the stacking arrangement here specifically refers to the light sensing element 30 and the adhesive area being colinear in the direction perpendicular to the display module so as to further utilize the space of the upper shell 10. The adhesive area and the light sensing element 30 are both arranged within the main structure of the upper shell 10 without occupying other areas inside and outside the display screen.

[0028] Further, based on the above-mentioned arrangement of the light sensing element 30, the first light guiding surface 510 of the light guiding column 50 can be designed with the same shape adaptability as the outer wall of the upper shell 10. The edge of the upper shell 10 of the commonly used display screen is usually designed as a rounded structure for the sake of aesthetics and safety. Therefore, the first light guiding surface 510 of the light guiding column 50 can also be designed as a curved surface structure. At the same time, it should be noted that part of the area on the first light guiding surface 510 is arranged toward the top of the display screen, while the other part of the area is arranged toward one side of the display screen, so that the first light guiding surface 510 can effectively transmit the light directly above and to the side of the display screen, and the light at the corresponding position is used The light in the direction of the user's commonly used viewing angle is an effective factor affecting the user's viewing experience of the display screen; at the same time, the second light-guiding surface 520 is a planar structure to cooperate with the light-sensing element 30. The second light-guiding surface 520 is specifically arranged in parallel with the sensing area of ​​the light-sensing element 30. Before the light reaches the second light-guiding surface 520, it passes through a straight light-guiding column 50 structure, and the light-sensing element 30 and the second light-guiding surface 520 are arranged close to each other, so that most of the light can directly reach the light-sensing element 30 from the second light-guiding surface 520, which simplifies the light transmission path, reduces the scattering and loss of light in the transmission process, and improves the accuracy of the light-sensing element 30's perception of external light.

[0029] It should also be noted that for the upper shell 10 with a partial frame of a right-angle structure, the first light-guiding surface 510 can also be adapted to be set as a bending structure with two vertical surfaces, which also has the ability to effectively transmit light directly above and to the sides of the display screen, thereby ensuring effective sensing of the light sensing element 30.

[0030] Furthermore, in some embodiments of the utility model, the light guide column 50 adopts an L-shaped structure and is fitted with the outer wall of the upper shell 10. The fitting setting here specifically refers to that the L-shaped light guide column 50 forms a continuous surface with the outer wall of the upper shell 10 after being assembled with the upper shell 10. The continuous structure not only gives people a simple and smooth feeling visually, but also provides better support and protection in structure, that is, the light guide column 50 completely fills the groove area on the upper shell 10, so that the outer frame of the outer shell maintains a complete structure, and there is no breakpoint area that affects the support and enclosure effect.

[0031] In order to further improve the accuracy and effectiveness of the self-adjustment effect of the brightness of the display screen, in some embodiments of the utility model, a light guide column 50 is respectively embedded and installed on the opposite sides of the upper shell 10, and preferably the two light guide columns 50 are symmetrically arranged on the upper shell 10, so as to give the user a balanced and harmonious intuitive feeling in terms of visual effect. At the same time, each light guide column 50 has a corresponding light sensing element 30, so that the light sensing element 30 can effectively receive the light on both sides of the display screen, and adjust the brightness of the display screen to meet the reading needs of the information on the display screen at both sides of the display screen, that is, the main and co-pilot positions. At the same time, it should be noted that the symmetrical layout of the light guide columns 50 also helps to reduce the problem of uneven brightness of the display screen under different lighting conditions. Since each light guide column 50 can independently provide light signals to the light sensing element 30, the display screen can make a comprehensive judgment based on the light changes on both sides, thereby achieving more accurate and balanced brightness adjustment; in addition, the symmetrical layout of the light guide columns 50 also simplifies the assembly and maintenance process of the display screen. Since the corresponding relationship between each light guide column 50 and the light sensing element 30 is clear and definite, it can be convenient for production and maintenance personnel to operate.

[0032] In order to further enhance the effect of the light guide column 50 in transmitting light outside the display screen, the side of the light guide column 50 may be coated with light-shielding ink to prevent light loss. Even other areas of the light guide column 50 except the first light guide surface 510 and the second light guide surface 520 may be coated with light-shielding ink to prevent unnecessary light interference and hide the non-functional parts of the light guide column 50, thereby ensuring that the light sensing element 30 can receive pure light signals in the corresponding direction, thereby improving the accuracy of light detection.

[0033] As in the aforementioned embodiment, the display module can be composed of two parts, namely, a screen 60 and a cover plate 70. The cover plate 70 covers the screen 60 and is adhesively connected to the upper shell 10 as a supporting structure, thereby improving the overall sealing performance of the display screen. At the same time, the cover plate 70 also helps to absorb and disperse the impact force when impacted by external force, thereby protecting the screen 60 from damage and improving the impact resistance of the display screen.

[0034] In addition, it should be noted that the material of the light guide column 50 can be a highly light-transmitting material such as polycarbonate, acrylic resin or epoxy resin. Among them, polycarbonate has excellent impact resistance and transparency, which can improve the impact resistance of the display screen; acrylic resin is favored for its excellent optical properties and processing properties, and is suitable for light guide columns 50 that require fine processing; epoxy resin is valued for its good adhesion and chemical corrosion resistance, and is suitable for display screens that need to be used in combination with a variety of materials; the above materials not only improve the performance of the light guide column 50, but also provide more flexibility and possibilities for the design and manufacture of display screens.

[0035] Furthermore, in the display screen provided in the embodiment of the utility model, after the upper shell 10 and the lower shell 20 are connected by snapping and aligning through the concave-convex structure, at least two connecting screws 80 that penetrate the printed circuit board 40 are used to fix them, so as to facilitate assembly and maintenance while maintaining the connection effect, and at the same time enable the printed circuit board 40 to be stably located in the accommodating cavity. It can also enable the upper and lower surfaces of the printed circuit board 40 to be exposed rather than being arranged in contact with the wall, thereby improving the heat dissipation performance of the upper and lower surfaces of the printed circuit board 40 during operation, thereby reducing the operating temperature of the circuit board and improving the stability and life of the display screen.

[0036] An embodiment of the utility model further provides a vehicle, which is provided with a display screen provided by any of the above embodiments in its central control area. The display screen provided by the above embodiments can ensure that the driver can clearly see the vehicle information under any lighting conditions, so as to make correct driving decisions. In addition, the automatic brightness adjustment function of the display screen can also reduce the driver's visual fatigue caused by light changes and improve driving safety. Since the display screen has the technical effects provided by the previous embodiments, the vehicle also has the above technical effects, which will not be repeated herein. It should also be noted that the vehicle can be a gasoline vehicle, an electric vehicle or a hybrid vehicle, etc.

[0037] It should be noted that, for the convenience of description, only the parts related to the utility model are shown in the drawings. In the absence of conflict, the embodiments and features in the embodiments of the utility model can be combined with each other.
