[Figure 3] Figure 3 is a front view of the LCD holder according to the embodiment. [Figure 4] Figure 4 is a cross-sectional view of a conventional display device along line AA. [Figure 5] Figure 5 is a front view of a conventional LCD holder. [Modes for carrying out the invention]
[0009] The embodiments of the display device disclosed herein will be described in detail below with reference to the attached drawings. However, the present invention is not limited to the embodiments described below.
[0010] Figure 1 is a front view of a display device according to an embodiment. As shown in Figure 1, the display device 10 has a cover glass 11 that covers the display and a front escutcheon 12 that holds the cover glass.
[0011] The display device 10 is installed inside the vehicle's cabin and accepts user input. For example, the display device 10 may be located on top of or inside the vehicle's instrument panel.
[0012] The display device 10 may be located on the back of the front seat and be operable from the rear seat.
[0013] The display device 10 displays information related to the car navigation system and the audio system. The display device 10 may also be part of the car navigation system.
[0014] Further, the display device 10 may display information related to the vehicle such as various meters. Further, the display device 10 may be equipped with a touch panel.
[0015] The user operates while looking at the display of the display device 10. At that time, it is conceivable that a part of the user's body such as the head collides with the display device 10 due to an impact on the vehicle.
[0016] Further, the cover glass 11 may be damaged by contact and form sharp edges.
[0017] Therefore, from the perspective of preventing user injury, the impact resistance of the device mounted on the vehicle may be defined by regulations.
[0018] One of the objects of the present embodiment is to increase the impact resistance of the display device 10 to such an extent that it can satisfy the regulations.
[0019] FIG. 2 is a cross-sectional view taken along line A-A of FIG. 1. As shown in FIG. 2, the display device 10 is entirely held by the front escutcheon 12 and the rear escutcheon 14.
[0020] Further, the cover glass 11 covers the entire display surface of the display 16. Also, there is a portion at the peripheral edge of the cover glass 11 that does not cover the display 16.
[0021] The front escutcheon 12 holds the peripheral edge of the cover glass 11 from the back side of the display 16. For example, the front escutcheon 12 is made of resin. However, the material of the front escutcheon 12 is not limited to resin and may be metal or the like.
[0022] Furthermore, the LCD (Liquid Crystal Display) holder 15 contacts the surface of the front escutcheon 12 opposite to the cover glass 11 and holds the display 16. For example, the LCD holder 15 is made of resin. However, the material of the LCD holder 15 is not limited to resin; it may also be made of metal or the like.
[0023] In the example shown in Figure 2, the LCD holder 15 is in contact with the front escutcheon 12 in region 101.
[0024] The reinforcing part 13 is in contact with the side of the LCD holder 15 opposite to the cover glass 11. For example, the reinforcing part 13 is made of pressed metal.
[0025] The front escutcheon 12 is an example of a first retaining part. The LCD holder 15 is an example of a second retaining part. The reinforcing part 13 is an example of a reinforcing part.
[0026] The impact on the cover glass 11 from the direction of impact shown in Figure 2 is absorbed by three components: the front escutcheon 12, the LCD holder 15, and the reinforcing part 13. This prevents damage to the cover glass 11. In this way, the display device 10 can protect the cover glass from impact with a simple structure.
[0027] Figure 3 is a front view of the LCD holder according to the embodiment. As shown in Figure 3, when viewing the LCD holder 15 from the cover glass 11 side, the extended portion corresponding to region 101 is visible.
[0028] The lateral range of the contact surface (region 101) of the LCD holder 15 with the front escutcheon 12 includes the central region of the cover glass 11 in the lateral direction, and the width L1 of the range is less than or equal to half the width L of the cover glass 11. Furthermore, L1 may be less than or equal to 1 / 10 of L.
[0029] This allows the impact on region 101 to be dissipated in the lateral direction. Furthermore, it allows for focused protection of areas that are particularly susceptible to impact.
[0030] Furthermore, the lateral range of the contact surface (region 101) of the LCD holder 15 with the front escutcheon 12 may extend across the entire lateral surface of the cover glass 11.
[0031] Figure 4 is a cross-sectional view of a conventional display device along line AA. The front view of the conventional display device 10a is the same as the front view of the display device 10 shown in Figure 1. Thus, the display device 10 of this embodiment has improved impact resistance without changing the design shape from the conventional one.
[0032] As shown in Figure 4, the cover glass 11a covers the display 16a. The LCD holder 15a also holds the display 16a.
[0033] The display device 10a is held in place by a front escutcheon 12a and a rear escutcheon 14a.
[0034] Furthermore, the front escutcheon 12a and reinforcing part 13a are positioned to absorb impacts to the cover glass 11.
[0035] However, as shown in Figure 4, there is a large gap between the LCD holder 15a and the reinforcing part 13a, which may indicate that the rigidity of the display device 10a is insufficient.
[0036] On the other hand, in this embodiment, as shown in Figure 2, the LCD holder 15 is an integrally molded member that contacts the front escutcheon 12, the side of the display 16, and the back of the display 16. The reinforcing part 13 is in close contact with the LCD holder 15 on the back of the display 16.
[0037] In this way, by configuring the front escutcheon 12 and reinforcing part 13 to sandwich the LCD holder 15, the gap is reduced and sufficient rigidity of the display device 10 can be ensured.
[0038] Furthermore, the reinforcing part 13 is a member processed by hemming bending, and the outer side of the bending position of the hemming bend is in contact with the LCD holder 15 (region 102).
[0039] The reinforcing part 13 in Figure 2 and the reinforcing part 13a in Figure 4 have different hemming bend positions. Therefore, reinforcing part 13 can be easily created by changing the bending position of the conventional reinforcing part 13a.
[0040] Furthermore, the vertical range of the contact surface between the LCD holder 15 and the front escutcheon 12 is greater than the thickness of the end of the LCD holder 15. This ensures even greater rigidity.
[0041] For example, as shown in Figure 4, the end of the LCD holder 15a is not in contact with the front escutcheon 12a.
[0042] Furthermore, even if the end of the LCD holder 15a is extended to contact the front escutcheon 12a, the area of the contact surface is only about the same as the cross-section of the LCD holder 15a, making it difficult to ensure sufficient rigidity.
[0043] Figure 5 is a front view of a conventional LCD holder. The conventional LCD holder 15a does not have an extended portion corresponding to region 101 in Figure 3.
[0044] As described above, the display device 10 includes a cover glass 11, a front escutcheon 12, an LCD holder 15, and a reinforcing part 13. The cover glass 11 covers the display surface of the display 16. The front escutcheon 12 holds the peripheral edge of the cover glass 11 from the back side of the display 16. The LCD holder 15 contacts the side of the front escutcheon 12 opposite to the cover glass 11 and holds the display 16. The reinforcing part 13 contacts the side of the LCD holder 15 opposite to the cover glass 11.
[0045] In this way, the impact on the cover glass 11 is absorbed by the three components: the front escutcheon 12, the LCD holder 15, and the reinforcing part 13. As a result, according to this embodiment, the cover glass can be protected from impact with a simple structure.
[0046] Further effects and modifications can be readily derived by those skilled in the art. Therefore, broader aspects of the present invention are not limited to the specific details and representative embodiments expressed and described above. Accordingly, various modifications are possible without departing from the spirit or scope of the overall concept of the invention as defined by the appended claims and equivalents.
