Abstract
Description
[Technical Field]
[0001] The present invention relates to a housing structure for a device mounted on a moving body. [Background technology]
[0002] A mobile-mounted device in which a main body having a control unit and a display unit for displaying images are mounted either integrally or separately is known and is described in Patent Document 1. The mobile-mounted device described in Patent Document 1 is a navigation device mounted in an automobile, which is a mobile body. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Japanese Patent Application Publication No. 2028-298766 Summary of the Invention [Problem to be solved by the invention]
[0004] The housing structure of the mobile-mounted device described in Patent Document 1 allows the display unit to be attached to the front of the main body unit, and the external size of the display unit is approximately the same as the external size of the front of the main body unit. On the other hand, in some car navigation devices and the like, the external size of the display unit is larger than the external size of the front of the main body unit, and in such cases the housing structure usually includes a dedicated metal mounting bracket to ensure the connection strength between the main body unit and the display unit, which has a large mass.
[0005] The dedicated mounting bracket is an unnecessary component for users who only use the mobile-mounted device in a separate state, and is a factor that creates an impression of increased costs. Also, for users who want to selectively use both the separate state and the integrated state, it is necessary to store the mounting bracket carefully so as not to lose it when using the device in a separate state. The housing structure of such a conventional mobile-mounted device, in which the external size of the detachable display unit is larger than that of the main body, leaves room for improvement in terms of reducing the impression of increased costs and improving user convenience.
[0006] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a housing structure for a mobile-mounted device that prevents users from feeling an increase in costs and improves convenience. [Means for solving the problem]
[0007] In order to solve the above-mentioned problems, a housing structure of a moving body-mounted device according to one aspect of an embodiment of the present invention has the following configuration 1). 1) A main body having a box-shaped housing including a top plate and a bottom plate; a display unit electrically connected to the main body unit to display an image; a bracket having a first plate portion and a second plate portion that are orthogonal to each other and having an L-shaped cross section; an integrated state in which an outer surface of the first plate portion is in contact with and fixed to the top plate or the bottom plate of the main body portion, and an outer surface of the second plate portion is in contact with and fixed to the display portion, so that the display portion is integrated with one side surface of the main body portion in an orthogonal orientation; a separate state in which the main body and the display unit are separated and separate, and one of the inner surfaces of the first plate and the second plate of the bracket is fixed to the top plate or the bottom plate of the main body so as to contact the top plate or the bottom plate of the main body, and the other serves as a cover plate to cover the one side surface; The housing structure of the mobile-mounted device is capable of switching between the above states. [Effects of the Invention]
[0008] According to the housing structure of the mobile-mounted device of the present invention, it is possible to obtain the effects of suppressing an increase in cost and improving convenience for users. [Brief explanation of the drawings]

[0010] A housing structure K for a moving body mounted device according to one aspect of an embodiment of the present invention will be described with reference to Figs. 1 to 4. Fig. 1 is a perspective view of a moving body mounted device TK equipped with a housing structure K according to a first aspect of an embodiment of the present invention, as viewed from diagonally above and behind the left. Fig. 2 is a perspective view of a moving body mounted device TK with the display unit 2 removed, as viewed from diagonally above and behind the left. Fig. 3 is a perspective view of a moving body mounted device TK in a separate state, as viewed from diagonally above and behind the left. Fig. 4 is a perspective view of a main body unit 1 of a moving body mounted device TK in a separate state, as viewed from diagonally above and behind the left.
[0011] For ease of explanation, the up, down, left, right, front and rear directions are defined as the directions of the arrows in FIG. 1. In one embodiment to be described, the mobile body is an automobile, and the mobile body-mounted device TK is a car navigation device. The mobile body-mounted device TK is attached to the dashboard of the mobile body. The front and rear directions in the following explanation are opposite to the front and rear directions of the automobile when the mobile body-mounted device TK is attached to the dashboard of the automobile.
[0012] As shown in FIG. 1, the mobile-mounted device TK includes a main body 1, a display 2, and a bracket 3. The main body 1 has a housing 11 that houses a control unit that controls the overall operation of the mobile-mounted device TK, an image processing unit, and the like. The housing 11 includes a top plate 11T and a bottom plate 11B (see FIG. 2) and is formed in a box shape that is thin in the vertical direction. As shown in FIG. 2, the front surface 1F, which is one side of the housing 11, is open, exposing the board 12 housed inside the housing and the receptacle 13 mounted on the board 12. The left and right portions of the front lower edge of the housing 11 have tongue portions 111 that are formed to stand up by bending the bottom plate 11B of the housing 11. The tongue portions 111 are formed with female threads.
[0013] The display unit 2 is a thin rectangular plate-like device that houses a display device. The image display surface of the display device faces forward in Fig. 1, and most of the front surface of the display unit 2 forms a rectangular opening that exposes the image display surface. The rear surface of the display unit 2 is provided with a pair of female threads 21 spaced apart on the left and right as shown in Fig. 3, and a plug 22 that connects to the receptacle 13 of the main body 1 is protruding and positioned slightly to the right of the center.
[0014] The bracket 3 is formed from a metal plate bent so that its cross section has an L-shape, and has flat first and second plate portions 35, 36. The two inner surfaces of the L shape are a first inner surface 351 of the first plate portion 35 and a second inner surface 361 of the second plate portion 36. The outer surface of the first plate portion 35 is a first outer surface 352, and the outer surface of the second plate portion 36 is a second outer surface 362.
[0015] As shown in Fig. 2, the second plate portion 36 has a rectangular opening 31 that is elongated from side to side at the bottom, slightly to the left of the center, and a through-hole 32 is formed near each of the upper left and right corners. A display unit fixing hole 33 is formed diagonally below the through-hole 32 and toward the center. A fastener N2, which is a screw, is passed through the display unit fixing hole 33 from the rear side. Furthermore, through-holes (not shown) are formed at the four corners of the first plate portion 35, through which the fastener N1 passes.
[0016] The mobile-mounted device TK can be in two states: an integrated state in which the display unit 2 is attached to the front surface 1F of the main body 1 and integrated therewith, and a separate state in which the display unit 2 is separated from the main body 1 and is a separate unit. In the separate state, the display unit 2 can be attached to a desired location by a mounting fixture (not shown), or the user can carry the display unit 2 around, allowing the user to view images in a desired location and position. In the separate state, the front surface of the housing 11 of the main body 1 is mostly covered by a bracket 3, as described below.
[0017] FIG. 1 shows the mobile-mounted device TK in an integrated state. FIG. 2 is a diagram of the mobile-mounted device TK in an integrated state, without showing the display unit 2. In the integrated state, the display unit 2 is attached to the front surface 1F, which is one side surface of the main body 1, via a bracket 3. In this example, the display unit 2 is attached in a position perpendicular to the main body 1. The bracket 3 is fixed to the front edge of the top plate of the housing 11 of the main body 1 with a fastener N1, with the first inner surface 351 of the first plate 35 facing outward and upward. In this example, the fastener N1 is four screws. In this position, the second plate 36 of the bracket 3 contributes to fixing the display unit 2. Specifically, as shown in FIG. 2, the second outer surface 362 of the second plate 36 contacts the rear surface opposite the display surface of the display unit 2, and fasteners N2, such as screws, inserted from the rear side into the display unit fixing holes 33 are screwed into the female threads 21 of the display unit 2, thereby fastening and fixing the display unit 2 to the bracket 3. At this time, the plug 22 (see FIG. 3) of the display unit 2 is inserted into the receptacle 13 of the main body 1, and the display unit 2 is electrically connected to the substrate 12 of the main body 1 and the like.
[0018] Fig. 3 shows the mobile-mounted device TK in a separate state, and Fig. 4 shows the main body 1 in a separate state. When the display unit 2 is removed in an integrated state, the front surface 1F of the main body 1 is opened, and the circuit board 12 and receptacle 13 are exposed as shown in Fig. 2. As shown in Figs. 3 and 4, the bracket 3 can be placed in a separate state in which the front surface of the main body 1 is closed by placing its second plate portion 36 against the front surface 1F of the main body 1 and fixing the first inner surface 351 of the first plate portion 35 to the upper part of the housing 11 of the main body 1 with a fixing device N1. In other words, the second plate portion 36 functions as a cover plate portion 37 that covers the front surface 1F.
[0019] Specifically, first inner surface 351 of first plate portion 35 of bracket 3 is brought into contact with top plate 11T of housing 11 and fastened with fastener N1. In this position, second plate portion 36 of bracket 3 closes the front surface of housing 11, and through hole 32 is positioned corresponding to the female thread portion of tongue portion 111 (see FIG. 2) of housing 11, so that fastener N1, which is a screw, is passed through through hole 32 and fastened to the female thread portion of tongue portion 111, as shown in FIG. 4. At this time, opening 31 of second plate portion 36 is positioned to expose receptacle 13, so that plug 811 of cable 81, which electrically connects plug 22 of display unit 2 to receptacle 13, can be inserted into receptacle 13 for electrical connection (see arrow DR81).
[0020] Since the housing structure K has the above-described configuration, the bracket 3 is used in both the integrated state and the separate state of the mobile-mounted device TK. That is, in the integrated state, it is used to fix the display unit 2, and in the separate state, it is used as a cover plate part 37 that mostly covers the front surface 1F of the housing 11 in the main body part 1. Therefore, the bracket 3 is also a necessary part for users who use the mobile-mounted device TK only in the separate state, so the sense of cost increase is suppressed. Furthermore, because the bracket 3 is used even in the separate state, the user does not need to take the trouble of storing the bracket 3, improving user convenience.
[0021] 1, when the inside dimensions in the direction perpendicular to the folding lines of the first plate portion 35 and the second plate portion 36 are widths A and B, respectively, the bracket 3 can be formed so that widths A and B are approximately equal and are also approximately equal to the outside height C of the housing 11. Here, approximately equal to height C means that the dimensions are set so that the front surface 11F of the housing 11 is mostly covered.
[0022] The relationship between the width A, width B, and height C is not limited to being approximately equal. For example, as shown in FIGS. 5A and 5B, the width B and height C may be approximately equal, with the width A being smaller than the width B. As shown in FIG. 5A, when the vertical length L2 of the display unit 2 in the integrated state is relatively small but greater than the height C, which is the vertical thickness of the main body 1, even if the width A is smaller than the width B, the bracket 3 can provide sufficient strength against tilting of the display unit 2 in the front-to-back direction, and can maintain the integrated state. As shown in FIG. 5B, which shows a separate state using the bracket 3 with different widths A and B, a second plate 36 of width B is attached to the cover of the front surface 1F of the housing 11 as a cover plate 37, and the first plate 35 is fixed to the top plate 11T of the housing 11.
[0023] 6A, the bracket 3 may be a bracket 3A having a reinforcing piece 311. The reinforcing piece 311 is formed so that the portion that becomes the upper edge of the opening 31 is bent inward and fits closely along the upper surface of the receptacle 13 when the bracket 3A is attached to the main body 1, which is in a separate state.
[0024] When using bracket 3A, as shown in Fig. 6A, it is preferable that the front ends of board 12 and receptacle 13 of main body 1 are flush with or protrude forward from the end face of opening 31. As a result, if receptacle 13 to which plug 811 is connected is pushed downward (toward board 12) by an unexpected external force (see arrow DR13B), board 12 moving downward will abut against the end face of the lower edge of opening 31, restricting excessive deformation. Also, if receptacle 13 is pushed upward (opposite board 12) and lifted (see arrow DR13U), receptacle 13 moving upward will abut against the underside of reinforcing piece 311, restricting excessive deformation. This prevents pattern peeling from occurring on board 12, improving the reliability of mobile-mounted device TK.
[0025] As shown in FIG. 7B, from the perspective of appearance quality, it is desirable that the vehicle-mounted device TK have as little gap as possible between the front end of the main body unit 1 and the rear surface of the display unit 2 in a side view in an integrated state. To achieve this, the longitudinal length of the portion of the housing 11 that becomes the cover plate portion 37 of the bracket 3 is shorter than the longitudinal (left-right) length of the front face 11F by the thickness of the left and right side plates, and the housing 11A is configured so that both side plates that form the left and right ends of the front face 11 protrude forward from the top plate 11T by at least the thickness t3 of the bracket 3. Specifically, for example, as shown in FIG. 7A, which is an enlarged perspective view of the front end of the left side plate 11L, the left side plate 11L protrudes forward from the top plate 11T by the thickness t3 of the bracket 3. As a result, when the bracket 3 is fastened to the top plate 11T as a separate body using the fastener N1, the end face of the second plate portion 36 that serves as the cover of the bracket 3 is hidden by the left side plate 11L in a side view, as shown in Fig. 7C, and the second outer surface 362 is flush with the front end 11Lf of the left side plate 11L (see also Fig. 7A), improving the appearance quality.
[0026] The embodiments of the present invention are not limited to the above-described configurations, and modifications may be made without departing from the spirit of the present invention.
[0027] The housing structure K is not limited to a case in which the brackets 3, 3A are attached to the top plate 11T of the housing 11, but may also be attached to the bottom plate 11B. That is, when the housing structure K is in a separate state, the bracket 3 is configured so that the inner surface 351, 361 of either the first plate portion 35 or the second plate portion 36 is fixed to either the top plate 11T or the bottom plate 11B of the housing 11 of the main body 1 by a fastener N1. The other becomes a cover plate portion 37 that covers the front surface 11F of the housing 11. The housing structure K can be switched between an integrated state and a separate state using the bracket 3.
[0028] The mobile body is not limited to an automobile, but may be a railroad vehicle, an airplane, a ship, a drone, etc. The mobile body-mounted device is not limited to a car navigation device, but may be a measuring device that measures and displays the body temperature of the passengers of the mobile body or the temperature inside the vehicle, a music playback device, a communication device, etc. [Explanation of symbols]
