The electronic device 1 comprises a display panel 2, a hinge portion 5, a hinge cover 7, and a main body portion 9 connected to the display panel 2 by a cable 6. The electronic device 1 is a so-called floating type in-vehicle device in which the display panel 2 is installed in a state where it protrudes from the vehicle's dashboard.

[0011] In the following explanation, the upper side of electronic device 1 during normal use will be referred to as the upper part of electronic device 1, and the lower side of electronic device 1 during normal use will be referred to as the lower part of electronic device 1. Also, in the following explanation, the left-right direction when viewing electronic device 1 from the occupant's side will be referred to as the left-right direction of electronic device 1. The direction from the driver's seat of the vehicle on which electronic device 1 is installed toward the windshield will be referred to as the front, and the opposite direction will be referred to as the rear. The front-rear direction will be the Z-axis direction. The left-right direction will be the X-axis direction. The up-down direction will be the Y-axis direction. The X-axis, Y-axis, and Z-axis directions are orthogonal in three dimensions.

[0012] The display device, the display panel 2, will be described using Figure 1. Figure 1 is a perspective view of the electronic device according to the embodiment, viewed from the front. The display panel 2 comprises a display unit 3 and a rear cover 4.

[0013] The display unit 3 is rectangular in shape and has a display surface that shows images directly in front of the occupants. The front is the surface that the vehicle occupants can see. In the case of a car navigation system, the front is the surface that faces the rear of the vehicle.

[0014] The rear cover 4 will be explained using Figure 2. Figure 2 shows the electronic device in Figure 1 with the hinge cover removed. The rear cover 4 is a cover that covers the rear of the display unit 3. The rear cover 4 is located on the back side of the display panel 2, opposite to the side on which the display surface is located. Because the rear cover 4 is located on the back side of the display unit 3, it is positioned in a location that is difficult for occupants to see when the electronic device 1 is mounted in a vehicle. The rear cover 4 comprises a cover portion 41, a support portion 42, a panel-side claw portion 43, a slit 44, and a projection portion 45.

[0015] The cover portion 41 is a plate-shaped component positioned opposite the back surface of the display portion 3. The cover portion 41 includes a support portion 42, a panel-side claw portion 43, a slit 44, and a projection portion 45. The support portion 42, the panel-side claw portion 43, the slit 44, and the projection portion 45 are located in the central part of the cover portion 41, excluding the right, left, and top portions.

[0016] The support portion 42 is positioned above the central part of the cover portion 41. The support portion 42 comprises a support portion 42R positioned to the upper right of the central part of the cover portion 41, and a support portion 42L positioned to the upper left of the central part. The support portions 42R and 42L are arranged as a pair, left and right. When it is not necessary to distinguish between the support portions 42R and 42L, they will be described as the support portion 42.

[0017] The support portion 42 is a plate-shaped part that protrudes forward from the cover portion 41. The support portion 42 supports the hinge cover 7 when the hinge cover 7, which will be described later, is assembled to the rear cover 4. The front end of the support portion 42 contacts the rear-facing surface of the hinge cover 7 when the hinge cover 7 is assembled to the rear cover 4.

[0018] The panel-side claw portion 43 is disposed above the central portion of the cover portion 41. The panel-side claw portion 43 includes a panel-side claw portion 43R disposed above the central portion of the cover portion 41 and a panel-side claw portion 43L disposed to the left of the panel-side claw portion 43R. The panel-side claw portion 43R and the panel-side claw portion 43L are arranged as a pair on the left and right. When the distinction between the panel-side claw portion 43R and the panel-side claw portion 43L is not necessary, it is described as the panel-side claw portion 43.

[0019] The panel-side claw portion 43 is disposed between a pair of left and right support portions 42. The panel-side claw portion 43 has a claw shape protruding forward from the cover portion 41. The panel-side claw portion 43 engages with the hinge cover 7. More specifically, the panel-side claw portion 43 engages with the receiving portion 731 of the hinge cover 7 in a state where the hinge cover 7 is assembled to the rear cover 4.

[0020] The slit 44 is disposed below the central portion of the cover portion 41. The slit 44 includes a slit 44R disposed at the lower right of the central portion of the cover portion 41 and a slit 44L disposed at the lower left of the central portion. The slit 44R and the slit 44L are arranged as a pair on the left and right. When the distinction between the slit 44R and the slit 44L is not necessary, it is described as the slit 44.

[0021] The slit 44 is a slit provided in the cover portion 41. The slit 44 is arranged along the vertical direction. The slit 44 engages with the slide portion 74 of the hinge cover 7 slidably when assembling the hinge cover 7 to the rear cover 4. The slit 44 guides the hinge cover 7 to the correct assembly position when assembling the hinge cover 7 to the rear cover 4. The slit 44 includes a wide portion 441 and a narrow portion 442. The wide portion 441 and the narrow portion 442 communicate with each other.

[0022] The wide portion 441 is wider in the left-right direction than the claw portion 742 of the sliding portion 74 of the hinge cover 7, which will be described later. When assembling the hinge cover 7 to the rear cover 4, the claw portion 742 of the sliding portion 74 is inserted from the front of the wide portion 441 and positioned behind the slit 44.

[0023] The narrow portion 442 communicates with the lower end of the wide portion 441. The narrow portion 442 is narrower in the left-right direction than the claw portion 742 of the sliding portion 74 of the hinge cover 7, which will be described later, and is slightly thinner in the left-right direction than the thickness of the engaging portion 741 of the sliding portion 74 of the hinge cover 7. When assembling the hinge cover 7 to the rear cover 4, the narrow portion 442 sandwiches the lower end of the engaging portion 741 of the sliding portion 74 of the hinge cover 7. When assembling the hinge cover 7 to the rear cover 4, the lower end of the engaging portion 741 of the sliding portion 74 of the hinge cover 7 slides while engaged with the narrow portion 442.

[0024] The projection 45 is a projection that prevents incorrect assembly when assembling the hinge cover 7 to the rear cover 4. When assembling the hinge cover 7 to the rear cover 4, if the lower end of the engaging portion 741 of the sliding portion 74 of the hinge cover 7 is engaged with the narrow portion 442, the projection 45 does not interfere with the hinge cover 7, and the hinge cover 7 can be properly assembled. When assembling the hinge cover 7 to the rear cover 4, if the lower end of the engaging portion 741 of the sliding portion 74 of the hinge cover 7 is not engaged with the narrow portion 442, the projection 45 interferes with the hinge cover 7, preventing the assembly of the hinge cover 7.

[0025] The projection 45 is positioned around the slit 44. The projection 45 is convex toward the hinge cover 7. The projection 45 comprises a projection 45R positioned around the slit 44R and a projection 45L positioned around the slit 44L. The projections 45R and 45L are positioned as a pair, left and right. When it is not necessary to distinguish between the projections 45R and 45L, they will be described as projection 45.

[0026] The projections 45 only need to be positioned on either the right or left side of the slit 44. In this embodiment, the projections 45 are positioned in pairs with the narrow portion 442 of the slit 44 in between.

[0027] The projection 45 may be positioned at any location along the longitudinal direction of the narrow portion 442 of the slit 44. In this embodiment, the projection 45 is positioned at the lower end of the narrow portion 442 of the slit 44.

[0028] When the hinge cover 7 is assembled to the rear cover 4, the rear cover 4 and the hinge cover 7 are fixed together by screws 49. The screws 49 are located below the support portion 42. The screws 49 consist of a screw 49R located below the support portion 42R and a screw 49L located below the support portion 42L. Screws 49R and 49L are arranged as a pair, left and right. When it is not necessary to distinguish between screws 49R and 49L, they will be described as screw 49.

[0029] The hinge portion 5 connects the back surface of the display panel 2 to the main body portion 9. The hinge portion 5 is a mounting member that allows the height of the display panel 2 to be adjusted and assembled to the main body portion 9. The hinge portion 5 is arranged as a pair, left and right, between a pair of left and right slits 44. The hinge portion 5 comprises a hinge portion 5R located to the left of slit 44R and a hinge portion 5L located to the right of slit 44L. When it is not necessary to distinguish between hinge portion 5R and hinge portion 5L, they will be described as hinge portion 5.

[0030] The hinge cover 7 will be described using Figure 3. Figure 3 is a perspective view of the hinge cover according to the embodiment. The hinge cover 7 is positioned on the back of the display panel 2 and covers the central part and the hinge part 5 of the rear cover 4. The hinge cover 7 is assembled to the rear cover 4 when the display panel 2 and the main body 9 are assembled to the vehicle. The hinge cover 7 comprises a cover part 71 and a sliding part 74.

[0031] The cover portion 71 is plate-shaped and positioned opposite the rear cover 4. The cover portion 71 is detachable from the rear cover 4. When the hinge cover 7 is assembled to the rear cover 4, the upper corner 72 of the cover portion 71 contacts the support portion 42 of the rear cover 4. When the hinge cover 7 is assembled to the rear cover 4, the upper right corner 72R of the cover portion 71 contacts the support portion 42R of the rear cover 4, and the upper left corner 72L of the cover portion 71 contacts the support portion 42L of the rear cover 4.

[0032] A receiving portion 731 is positioned on the upper part 73 of the cover portion 71. The receiving portion 731 of the cover portion 71 is a recess into which the panel-side claw portion 43 of the rear cover 4 engages when the hinge cover 7 is assembled to the rear cover 4. When the hinge cover 7 is assembled to the rear cover 4, the panel-side claw portion 43R of the rear cover 4 engages with the receiving portion 731R of the cover portion 71, and the panel-side claw portion 43L of the rear cover 4 engages with the receiving portion 731L of the cover portion 71. The receiving portions 731R and 731L are positioned as a pair, left and right.

[0033] The sliding portion 74 is located on the side of the hinge cover 7 that faces the back surface of the display panel 2 (the back surface that is not exposed to the outside of the hinge cover 7 in the assembled state). The sliding portion 74 is a slider that can slide along the slit 44 while engaged with the slit 44 of the rear cover 4. The sliding portion 74 includes a sliding portion 74R located to the lower right of the cover portion 41 that can engage with the slit 44R, and a sliding portion 74L located to the lower left that can engage with the slit 44L. The sliding portions 74R and 74L are arranged as a pair, left and right. When it is not necessary to distinguish between the sliding portions 74R and 74L, they will be described as the sliding portion 74. The sliding portion 74 includes an engaging portion 741 and a claw portion 742. The engaging portion 741 and the claw portion 742 are formed as a single unit.

[0034] The engaging portion 741 is erected from the side of the hinge cover 7 that faces the back surface of the display panel 2 (the back surface that is not exposed to the outside of the hinge cover 7 when assembled). The engaging portion 741 is plate-shaped. The engaging portion 741 is slidable by engaging with the narrow portion 442 of the slit 44 of the rear cover 4.

[0035] The claw portion 742 is positioned at the end of the engaging portion 741. The claw portion 742 has a shape that protrudes from the engaging portion 741 in at least one direction to the left or right. In this embodiment, the claw portion 742 is a plate-shaped member positioned facing a different direction from the engaging portion 741. In this embodiment, the claw portion 742 and the engaging portion 741 are perpendicular to each other. In this embodiment, the claw portion 742 and the engaging portion 741 form an L-shape when viewed in the vertical direction.

[0036] <Methods for assembling electronic equipment> Next, the assembly method and operation of the hinge cover 7 of the electronic device 1 will be explained. Before assembling the hinge cover 7, the main body 9 and display panel 2 of the electronic device 1 are mounted on the vehicle's dashboard with the cable 6 connected. It is difficult for a worker positioned on the driver's side to visually inspect the rear cover 4 and hinge cover 7, which are located behind the display unit 3 of the display panel 2.

[0037] Figure 4 is a magnified view of the assembled hinge cover and rear cover according to the embodiment. The claw portion 742 of the sliding portion 74 of the hinge cover 7 is inserted from the front of the wide portion 441 of the slit 44 of the rear cover 4 and positioned behind the slit 44. This causes the lower part of the engaging portion 741 of the sliding portion 74 to engage with the narrow portion 442 of the slit 44. In this state, the sliding portion 74 is slid downward along the slit 44. After sliding the sliding portion 74 along the slit 44 to a predetermined position (appropriate assembly position), the panel-side claw portion 43 of the rear cover 4 is pushed into the receiving portion 731 and engaged. With the panel-side claw portion 43 of the rear cover 4 engaged with the receiving portion 731, the rear cover 4 and the hinge cover 7 are fixed together with screws 49. In this way, the hinge cover 7 is assembled to the rear cover 4.

[0038] <An example of incorrect assembly> Figure 5 is a magnified partial view showing an example of an incorrect assembly state of the hinge cover and rear cover according to the embodiment. When the claw portion 742 is positioned above the slit 44 of the rear cover 4 when sliding, in other words, when the engaging portion 741 of the sliding portion 74 of the hinge cover 7 is not engaged with the slit 44 of the rear cover 4 when sliding, the projection 45 comes into contact with the claw portion 742 and restricts the sliding of the hinge cover 7. As a result, the hinge cover 7 cannot be assembled to the rear cover 4 to the appropriate assembly position where it can be fastened with the screws 49.

[0039] <Other examples of incorrect assembly> Figure 6 is a magnified partial view showing another example of an incorrect assembly state of the hinge cover and rear cover according to the embodiment. When the hinge cover 7 is brought close to the rear cover 4 with the engaging portion 741 of the sliding portion 74 of the hinge cover 7 not engaged with the slit 44 of the rear cover 4, the projection 45 contacts the claw portion 742, restricting the approach of the hinge cover 7 and the rear cover 4. As a result, the hinge cover 7 cannot be assembled to the rear cover 4 to the appropriate assembly position where it can be fastened with the screws 49.

[0040] <Effects> As described above, in this embodiment, the rear cover 4 is provided with a slit 44 and a projection 45 that is convex toward the hinge cover 7. In this embodiment, the hinge cover 7 is provided with a sliding portion 74 which includes an engaging portion 741 that engages with the slit 44 and slides, and a claw portion 742. In this embodiment, when assembling the hinge cover 7 to the rear cover 4, if the engaging portion 741 of the hinge cover 7 is not engaged with the slit 44 of the rear cover 4, the claw portion 742 of the sliding portion 74 comes into contact with the projection 45 of the rear cover 4. According to this embodiment, even if the worker cannot visually inspect the rear cover 4 and the hinge cover 7, it is easy to recognize that the hinge cover 7 is not in the correct position relative to the rear cover 4. According to this embodiment, it is possible to easily assemble the hinge cover 7 to the correct position relative to the rear cover 4.

[0041] In this embodiment, if the hinge cover 7 slides with the engaging portion 741 of the sliding portion 74 not engaged with the slit 44 of the rear cover 4, the projection 45 can contact the claw portion 742 and restrict the sliding. As a result, in this embodiment, the hinge cover 7 cannot be assembled to the rear cover 4 to a suitable assembly position where it can be fastened with the screws 49. According to this embodiment, the hinge cover 7 can be easily assembled to the rear cover 4 in a suitable position.

[0042] In this embodiment, when the hinge cover 7 is brought close to the rear cover 4 while the engaging portion 741 of the sliding portion 74 of the hinge cover 7 is not engaged with the slit 44 of the rear cover 4, the projection 45 contacts the claw portion 742, thereby restricting the approach between the hinge cover 7 and the rear cover 4. As a result, in this embodiment, the hinge cover 7 cannot be assembled to the rear cover 4 to a suitable assembly position where it can be fastened with the screws 49. According to this embodiment, the hinge cover 7 can be easily assembled to the rear cover 4 in a suitable position.

[0043] In this embodiment, the slit 44 of the rear cover 4 has a wide portion 441 that is wider than the claw portion 742 of the sliding portion 74 of the hinge cover 7, and a narrow portion 442 that is narrower than the claw portion 742 and thinner than the thickness of the engaging portion 741. In this embodiment, rattling can be suppressed by engaging the engaging portion 741 of the sliding portion 74 of the hinge cover 7 with the narrow portion 442 of the slit 44. According to this embodiment, because the slit 44 has a wide portion 441, the sliding portion 74 of the hinge cover 7 can be easily assembled into the slit 44.

[0044] In this embodiment, the projection 45 of the rear cover 4 is positioned on either side of the narrow portion 442 of the slit 44. According to this embodiment, it is easy to recognize that the sliding portion 74 of the hinge cover 7 is not in the appropriate position relative to the slit 44 of the rear cover 4.

[0045] The above-described components include those that are easily conceivable by those skilled in the art, and those that are substantially identical. Furthermore, the above-described components can be combined as appropriate. In addition, various omissions, substitutions, or modifications of the components are possible without departing from the spirit of the present invention.

[0046] <Variation> In the above description, the claw portion 742 and the engaging portion 741 are assumed to be L-shaped when viewed in the vertical direction, but this is not the only possible configuration. The claw portion 742 and the engaging portion 741 may also be T-shaped when viewed in the vertical direction. The claw portion 742 simply needs to be wider in the horizontal direction than the engaging portion 741. [Explanation of symbols]
