Description

Technical Field

[0001] The present invention relates to a display device, and more specifically, to a display device having a circuit board on which electronic components are disposed. Background Technology

[0002] In general vehicle display devices, in addition to speed display and fuel level display, multiple indicators (appearance parts) such as indicator lights and warning lights are also provided (for example, see Patent Document 1).

[0003] For example, in directional indicator lights, right-turn and left-turn lights are mostly arranged symmetrically (or vertically) around the center of the display device. Furthermore, since high-beam lights (which illuminate when the light is set to high) and automatic high-beam lights (which are set to automatically switch between high and low states based on the presence or absence of an object ahead) have similar appearances, it is preferable to arrange them in a well-balanced manner on the display device, either horizontally (or vertically).

[0006] Patent Document 1: Japanese Patent Application Publication No. 2017-181158 ( Figure 1 ) Summary of the Invention

[0007] The technical problem that the invention aims to solve

[0008] However, since the number and type of indicators installed on the display device vary depending on the vehicle model and class, there are sometimes limitations on their placement. Therefore, even when indicators with similar appearances or symmetrical (or vertically symmetrical) appearances are installed on the display device, they cannot be arranged symmetrically with the center of the display device as a reference, which may degrade the design of the display device.

[0009] The present invention was made in view of such circumstances, and its object is to provide a display device that can improve the freedom and design flexibility of the placement of the exterior parts.

[0010] Technical solutions adopted to solve technical problems

[0011] To solve the above problems, the display device of the present invention includes: a circuit board; a housing that houses the circuit board therein; and a light shield disposed on the front opening of the housing in a manner opposite to the circuit board. The housing has a partition wall that divides the space enclosed by the circuit board, the light shield, and the peripheral wall of the housing into a first partition that does not include a position that is the center when viewed from the front of the display device, and a second partition that includes the center position. In the first partition, a first electronic component is disposed on the circuit board; in the second partition, a second electronic component is disposed on the circuit board at a location that avoids the center position. A first and second light-transmitting external portion are formed on the light shield in a manner corresponding to the positions of the first and second electronic components. In the first partition, if the first electronic component is not disposed on the circuit board, the second electronic component is disposed at the center position of the circuit board, and a third light-transmitting external portion is formed on the light shield in a manner corresponding to the position of the second electronic component.

[0012] Here, the first electronic component refers to the electronic component disposed on the circuit board in the first partition, and the second electronic component refers to the electronic component disposed on the circuit board in the second partition. Therefore, the first electronic component and the second electronic component are electronic components disposed in different partitions (dispositions) on the circuit board. The first electronic component and the second electronic component can be the same electronic component or different electronic components.

[0022] Figure 8 This is a front view showing an example of the display device's arrangement relative to a vehicle's instrument panel. Detailed Implementation

[0023] Examples of the display device of the present invention will be described in detail with reference to the accompanying drawings. Figure 1 This is a front view showing the instrument panel of a vehicle equipped with a display device. Figures 2-4 This is a cross-sectional view showing the display devices with different LED light source placement positions, as described later. Figure 3 It is shown Figure 1 The image shows a cross-sectional view of the display device along section II-II, illustrating the case where two LED light sources are mounted on the circuit board. Figure 4 This shows the case where only one LED light source is used.

[0024] like Figure 1 As shown, a liquid crystal display 102 is provided on the vehicle instrument cluster 100, capable of displaying vehicle speed information or the operating status of ADAS (Advanced Driver Assistance System). An edge portion 103 is provided around the display 102. To ensure that the edge portion 103, excluding the information display area of ​​the display 102, is not conspicuous when the user views the vehicle instrument cluster 100 from the front, the edge portion 103 is composed of a light-shielding member (light-shielding plate).

[0025] like Figures 1-4 As shown, a display device 1 is provided in the lower center of the vehicle instrument 100. The display device 1 is generally composed of a housing 10, a circuit board 20, and an edge portion 103.

[0026] The housing 10 is box-shaped to accommodate the circuit board 20, and is located on the front side of the vehicle instrument panel 100 (display 102). Figures 2-4 An opening 11 is formed on the upper side of the casing 10. The circuit board 20 is located near the bottom surface 12 of the casing 10.

[0027] The edge portion 103 is composed of a light-blocking component as described above, and more specifically, it is formed by bonding a light-blocking sheet 105 to the surface of a light-transmitting plate 104. A light-transmitting appearance portion 106 can be formed on the light-blocking sheet 105. Figure 3 The diagram shows a state in which two exterior portions 106a and 106b are formed. In the embodiment, exterior portion 106a is referred to as the first exterior portion, and exterior portion 106b is referred to as the second exterior portion.

[0028] The housing 10 is provided on the vehicle instrument panel 100 such that the bottom surface of the edge portion 103 covers the front opening 11 of the housing 10. Therefore, the bottom surface of the edge portion 103 is in a state opposite to the circuit board 20.

[0029] Furthermore, the housing 10 is positioned such that its center line (centerline) when viewed from the front coincides with the center line (centerline) of the vehicle instrument cluster 100 (display 102 and edge portion 103) when viewed from the front. More specifically, the housing 10 is positioned such that the centerline CLC of the housing 10 (refer to...) Figures 2-4 The center line CLD1 (see reference) is included in the center of the vehicle instrument panel 100 (display 102 and edge portion 103) and extends vertically along the screen of the display 102. Figure 1 The instrument panel 100 (edge ​​103) is mounted in a planar manner on the vehicle instrument panel 100.

[0030] A partition wall 15 is provided in the housing 10, which divides the internal space of the housing 10 (the space enclosed by the circuit board 20, the side walls (peripheral walls) 13 of the housing 10, and the edge portion 103) into at least two parts. The internal space of the housing 10 is divided into a first partition S1 that does not include the center of the housing 10 (the position through which the center line CLC passes, which is the center position), and a second partition S2 that includes the center of the housing 10 (the position through which the center line CLC passes, which is the center position). In addition, besides the partition wall 15, other partition walls 16, 16 are provided on the housing 10 near the side walls 13 of the housing 10 to divide the space near the end of the circuit board 20.

[0031] Various electronic components are disposed on the upper surface of the circuit board 20. For example, light-emitting elements such as LEDs are provided as one example of electronic components. Figure 3 In this circuit, an LED light source (first electronic component) 31 is provided on the circuit board 20 of the first partition S1, and an LED light source (second electronic component) 32 is provided on the circuit board 20 of the second partition S2. Figure 3As shown, when the first partition S1 is equipped with an LED light source 31, the LED light source 32 in the second partition S2 is linearly symmetrical about the positions of the LED light source 31 in the first partition S1 and the LED light source 32 in the second partition S2, with the center line CLC of the housing 10 as the reference (or, with...). Figure 3 The position of point O1 on the center line CLC shown is symmetrical to the reference point.

[0032] Furthermore, the aforementioned first outer portion 106a is formed on the sheet 105 directly above the location where the LED light source 31 is positioned (corresponding to the location of the LED light source 31). Similarly, the second outer portion 106b is formed on the sheet 105 directly above the location where the LED light source 32 is positioned (corresponding to the location of the LED light source 32). The sheet 105 has high light-shielding properties, while both the first and second outer portions 106a and 106b are light-transmitting. Therefore, when the LED light source 31 in the first section S1 is lit, the user can visually perceive the light transmitted through the first outer portion 106a. Similarly, when the LED light source 32 in the second section S2 is lit, the user can visually perceive the light transmitted through the second outer portion 106b.

[0033] On the other hand, when the LED light source 31 of the first partition S1 is off, the edge portion 103 is formed by a light-shielding member, and the first partition S1 and the second partition S2 are divided into two by the partition wall 15. The light from the LED light source 32 of the second partition S2 will not enter the first partition S1. Therefore, regardless of whether the LED light source 32 of the second partition S2 is on or off, the user will have difficulty visually recognizing the first appearance portion 106a and will not be aware of the first appearance portion 106a. The same situation applies when the LED light source 32 of the second partition S2 is off.

[0034] Thus, in the display device 1 according to the embodiment, the LED light source 31 of the first partition S1 and the LED light source 32 of the second partition S2 are arranged in a line symmetrical manner with respect to the center line CLC of the housing 10 (or, with... Figure 3 The first and second appearance parts 106a and 106b, which are corresponding to LED light sources 31 and 32, are also formed in a position that is line-symmetrical with respect to the center line CLD1 of the vehicle instrument panel 100 (display 102 and edge part 103). Figure 1The first and second appearance parts 106a and 106b, which are visually recognizable by the user through the illumination and extinguishing of LED light sources 31 and 32, are visually recognizable from the center line CLD1 of the vehicle instrument 100 in a well-balanced left-right configuration, thus improving the design of the vehicle instrument 100 (and appearance parts 106).

[0035] like Figure 3 As shown, when two LED light sources 31 and 32 and two external parts 106a and 106b are provided in the display device 1, they can be well balanced and arranged from the center line CLD1 of the vehicle instrument 100. However, when only one LED light source is provided in the display device 1, the following method is generally adopted: retain one of the LED light source 31 in the first section S1 and the LED light source 32 in the second section S2, and remove the other one from the circuit board 20, thus limiting the LED light source to one. This is because even if different vehicle models are used, a universal housing 10 is mostly used, and the shape of the housing 10, the position of the partition wall 15, etc., cannot be easily changed according to the setting position of the LED light source.

[0036] In the display device 1 according to the embodiment, it is envisioned that only one LED light source is provided, and the partition wall 15 is provided in such a way that it is divided into a first partition S1 and a second partition S2, which are partitions (spaces) that do not include the center of the housing 10 (the position through which the center line CLC passes) and a partition (space) that includes the center of the housing 10 (the position through which the center line CLC passes).

[0037] Figure 4 This is a cross-sectional view of a display device 1 with only one LED light source mounted on the housing 10. The LED light source (second electronic component) 33 is positioned at the second partition S2, which is the center of the circuit board 20 (point O1 on the center line CLC). Furthermore, a third appearance portion 106c is formed on the sheet 105 directly above the position where the LED light source 33 is mounted. By forming the third appearance portion 106c on the sheet 105 in this way, the third appearance portion 106c, which is visually recognizable to the user when the LED light source 33 is illuminated, is visually recognizable on the center line CLD1 of the vehicle instrument cluster 100, thus improving the design of the vehicle instrument cluster 100 (and the appearance portion 106).

[0038] Furthermore, a universal housing 10 can be used whether only one LED light source 33 is provided relative to the housing 10 or two LED light sources 31 and 32 are provided. Therefore, it is not necessary to prepare multiple housing shapes according to the installation position and number of LED light sources, and the component (housing 10) can be universalized. In addition, even when using a universal housing 10, the appearance part 106 can be freely designed, thus increasing the flexibility of the configuration of the appearance part 106.

[0039] Furthermore, the outer surface 106 (the part that transmits light) can be easily formed by printing or other processes on the sheet 105. Therefore, the formation position of the outer surface 106 can be easily changed to correspond to the placement position of the LED light sources 31-33. Additionally, even if multiple sheets 105 with different formation positions for the outer surface 106 are prepared in advance, the cost of the vehicle instrument 100 will not increase. Moreover, since the circuit board 20 has a wiring diagram design, preparing a board with two LED light sources 31 and 32 and a board with only one LED light source 33 will not lead to increased costs due to different wiring diagram designs.

[0040] Figure 5 Show replacement Figure 3 The cross-sectional view shown is of a display device 1 with an LED light source 31 in the first partition S1 and a photoelectric sensor (first electronic component) 34. Even in cases such as Figure 5 When the photoelectric sensor (first electronic component) 34 is provided as shown, it can also be used with... Figures 2-4 The housing shown is the same as the housing 10. Furthermore, even if the position of the photoelectric sensor 34 in the first partition S1 is different from the position of the LED light source 31 (when the position of the photoelectric sensor (first electronic component) 34 and the formation position of the first appearance part 106a are offset relative to the front direction of the display device 1), by providing a light guide 40, which is bent so that its lower end is directly above the photoelectric sensor 34 and its upper end is directly below the first appearance part 106a, in the first partition S1, the light incident through the first appearance part 106a can be effectively guided to the photoelectric sensor 34 without changing the position of the first appearance part 106a (without compromising the balance of the configuration with the second appearance part 106b).

[0041] Furthermore, a light guide can be provided in the second partition S2. By providing a light guide in the second partition S2, whether the LED light source is positioned at the center (the position through which the center line CLC passes) when viewed from the front of the circuit board 20, or at a position offset from the center (the position through which the center line CLC passes) of the circuit board 20, the light from the LED light source can be effectively transmitted to the appearance section 106, making it easy for the user to visually identify.

[0042] Figure 6 It is shown in Figure 5 The diagram shows a cross-sectional view of the display device 1 with the light guide 41 installed in the second partition S2. By installing the light guide 41 in the second partition S2, when the LED light source 32 is installed on the circuit board 20, the light from the LED light source 32 can be effectively guided to the second appearance part 106b.

[0043] On the other hand, such as Figure 7 As shown, even when an LED light source 33 is configured at the location where the center line CLC of the second partition S2 passes (the location of point O1), by directly utilizing Figure 6 The housing 10 and light guide 41 shown can also effectively guide the light from the LED light source 33 to the third exterior part 106c. Furthermore, in relation to... Figure 3 When the second partition S2 of the display device 1 shown is equipped with a light guide 41, it also achieves the same effect.

[0044] The above description of the display device of the present invention has taken a vehicle instrument 100 equipped with display device 1 as an example, but the display device of the present invention is not limited to the structure of display device 1 shown in the embodiment.

[0045] For example, in the embodiment of the display device 1, the case where the display device 1 is provided at the edge portion 103 of the vehicle instrument panel 100 is described, but the display device of the present invention is not limited to the structure provided at the edge portion 103. For example, in the case where the display 102 is not a liquid crystal display but an instrument device with a pointer display composed of a dial and a pointer portion, the sheet 105 of the display device 1 is formed into a dial, and the display device 1 is provided at the center portion of the vehicle instrument panel 100 (the portion inside the edge portion 103), thereby enabling the appearance portion 106 to be used as an indicator (indicator light, warning light) provided on the vehicle instrument panel 100.

[0046] Specifically, regarding the design of the exterior section 106, by using the appearance of the turn indicator lights (appearances where the same appearance is reversed left and right) and the appearance of the high beam indicator lights (similar appearances), the left and right arrangement of the turn indicator lights, etc., in the vehicle instrument cluster 100 can be balanced and well-proportioned with respect to the center line CLD1 (or with respect to point O2). Furthermore, by arranging the indicator lights, etc., at positions on the center line CLD1 (or, at the position of point O2), the indicators can be balanced and well-proportioned in the center position. Therefore, when the user visually identifies the indicator lights or warning lights, the well-proportioned indicators can be recognized, thus eliminating the visual disharmony caused by the indicator lights being on or off, and improving visual recognizability. In addition, this arrangement of indicators enhances the design aesthetics of the vehicle instrument cluster 100.

[0047] Furthermore, the universal housing 10 can be used even if the indicator is positioned differently, thus enabling the standardization of the component (housing 10). In addition, even when using the universal housing 10, the flexibility in the arrangement of the exterior part 106 can be increased.

[0048] Furthermore, in the embodiment of the display device 1, it is described that the display device 1 is provided at the lower edge 103 of the vehicle instrument panel 100, but the position of the display device of the present invention is not limited to the lower edge 103 of the vehicle instrument panel 100. For example, as Figure 8 As shown, the display device 1 can be positioned either at the lower edge 103 position 50 or the upper edge 103 position 51 of the vehicle instrument panel 100. Even in this configuration, since the two external parts 106 are well-balanced left and right relative to the center line CLD1 of the vehicle instrument panel 100, they can achieve the same effect as the display device 1 shown in the embodiment.

[0049] In addition, such as Figure 8 As shown, the structure can also be as follows: the display device 1 is positioned at position 52 on the right edge 103 of the vehicle instrument panel 100, or at position 53 on the left edge 103 of the vehicle instrument panel 100, and the two exterior parts 106 are arranged vertically. In this way, even when two exterior parts 106 are arranged, the two exterior parts 106 are well balanced vertically with respect to the center line CLD2 extending horizontally towards the vehicle instrument panel 100, thereby achieving the same effect as the display device 1 shown in the embodiment.

[0050] Furthermore, in the display device 1 described in the embodiment, LED light sources 31 to 33 and photoelectric sensors 34 are provided as electronic components provided on the circuit board 20. However, the electronic components provided on the circuit board 20 are not limited to these, and different electronic components may be provided.
