  Next, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram for explaining a lid mounting structure and an electronic device according to an embodiment of the present invention. The electronic device 1 includes a case 2 and a bottom plate 9 as shown in FIG. The case 2 is a resin molded product, and has a rear panel 3, a right side surface 4, a left side surface 5, a back surface 6, and an upper surface 7, and the lower surface is opened. The bottom plate 9 is formed by molding a metal sheet metal and is attached to a lower opening portion of the case 2.

  The rear panel 3 is a mounting panel to which the lid 20 is attached. As shown in FIG. 1B, the rear panel 3 is formed with an opening 10 to which a lid 20 is attached together with a hole in which a switch or the like is disposed. The opening 10 is formed at a position facing an adjustment connector (not shown) that is not used during normal operation but is used during adjustment.

  The opening 10 has a rectangular shape as shown in an enlarged view in FIG. Specifically, the opening 10 has a rectangular shape with long sides in the directions of arrows X1 and X2 in the drawing and short sides in the directions of arrows Y1 and Y2.

  In addition, a bearing portion 11 that is recessed in a curved shape is formed at a central position in the longitudinal direction of the opening 10. Furthermore, an engagement convex portion 12 (corresponding to a second engagement portion described in claims) is formed at a position on one diagonal line at the outer peripheral position of the opening portion 10. The engagement convex portion 12 is formed so as to protrude outward from the rear panel 3.

  A lid 20 is attached to the opening 10. The lid 20 covers the opening 10 formed at a position facing the adjustment connector, so that foreign matter is erroneously inserted into the adjustment connector through the opening 10 or inside the case 2 through the opening 10. It has a function of preventing dust from entering the door. However, at the time of adjustment or the like, it is desirable that the lid 20 is easily attached to and detached from the rear panel 3 (case 2).

  Next, the structure of the lid 20 will be described with reference to FIGS. FIG. 2 is a perspective view of the lid 20, and FIG. 3 is a six-face view of the lid 20.

  The lid body 20 is configured such that a main body portion 21, a shaft portion 22, an engagement portion 23, an engagement recess 24, and the like are integrally formed. The main body portion 21 has a rectangular shape, and the size of the main body portion 21 is such that the opening portion 10 can be covered and closed when attached to the case 2. A large number of slits are formed on the surface 21a of the main body portion 21 in terms of design.

Further, a shaft portion 22, an engagement portion 23, and an engagement recess 24 are formed on the back surface 21 b of the main body portion 21. The shaft portion 22 is formed so as to protrude to the center position of the back surface 21 b of the main body portion 21. The formation position of the shaft portion 22 is set so as to correspond to the bearing portion 11 formed in the opening portion 10. The diameter D1 of the shaft portion 22 is set to be equal to or slightly smaller than the diameter D2 of the bearing portion 11 (D1 ≦ D2).
Two engaging portions 23 are formed in a hook shape on the shaft portion 22. The two engaging portions 23 are formed so as to extend in a direction perpendicular to the protruding direction of the shaft portion 22, that is, in a direction parallel to the back surface 21b. The two engaging portions 23 are formed so as to face each other with the shaft portion 22 in between (180 ° apart).

  The length of the pair of engaging portions 23 (indicated by the arrow H1 in the drawing) is shorter than the length of the long side of the opening 10 (indicated by the arrow x in FIG. 1C), and the opening portion. It is set to be longer than the length of 10 short sides (indicated by an arrow y in FIG. 1C) (x ≧ H1, y ≦ H1). The width dimension of the engaging portion 23 (indicated by an arrow H2 in the figure) is set to be shorter than the length of the short side of the opening 10 (indicated by the arrow y in FIG. 1C). Further, the separation distance between the engagement portion 23 and the back surface 21b (indicated by an arrow ΔW in FIG. 2A) is set to be the same as or slightly smaller than the thickness of the rear panel 3.

  The engagement recess 24 (corresponding to the first engagement portion described in the claims) is the back surface 21b of the main body portion 21, that is, a position facing the rear panel 3 when mounted, and is one of the back surface 21b. It is formed at a position on a diagonal line. The formation positions of the pair of engagement recesses 24 are formed so as to correspond to the formation positions of the engagement protrusions 12 formed on the rear panel 3.

  A guide groove 25 is formed on the back surface 21b. The guide groove 25 has a function of guiding the relative movement of the engaging projection 12 formed on the rear panel 3 when the lid 20 is rotated to be attached to the rear panel 3 as will be described later.

  The width dimension of the guide groove 25 is L1 at the entry position where the engagement protrusion 12 enters as the lid 20 rotates, and the width dimension at the position where the engagement depression 24 is formed (referred to as the engagement position). In the case of L2, L1 is set to be larger than L2 (L1> L2) and gradually narrow from the approach position toward the engagement position.

  Further, the protruding portion 26 in which the engaging recess 24 is formed protrudes from the bottom surface of the guide groove 25, and an inclined surface 27 is formed between the protruding portion 26 and the bottom surface of the guide groove 25. Is formed. Therefore, when the engaging convex portion 12 relatively advances in the guide groove 25 with the rotation of the lid body 20, it rises up the inclined surface 27 to the protruding portion 26 and then engages with the engaging concave portion 24. Match.

  Next, the operation of attaching the lid 20 to the rear panel 3 in the lid 20 mounting structure having the opening 10 and the lid 20 will be described.

  In order to attach the lid 20 to the rear panel 3, first, the extending direction of the engaging portion 23 is set to the direction in which the long side direction (X1, X2 direction) of the opening 10 coincides, and the shaft portion 22 of the lid 20 and the opening After positioning the 10 bearing portions 11, the engaging portion 23 is inserted into the opening 10 (this state is referred to as an inserted state).

  FIG. 4 shows a state where the engaging portion 23 is inserted into the opening 10. As described above, the length H1 of the engaging portion 23 is smaller than the length x of the long side of the opening 10, and the width H2 of the engaging portion 23 is shorter than the length y of the short side of the opening 10. The engaging portion 23 can be easily inserted into the engaging portion 23. FIG. 4 shows a state in which the engaging portion 23 is inserted into the opening 10.

  Next, the lid 20 is rotated 90 ° with respect to the rear panel 3 in the direction of the arrow A1. The shaft portion 22 of the lid 20 is supported by the bearing portion 11 of the opening 10. For this reason, when the lid 20 is rotated in the A1 direction, the shaft portion 22 rotates in the A1 direction within the bearing portion 11.

  As described above, the length H <b> 1 of the engaging portion 23 is longer than the length y of the short side of the opening 10. For this reason, when the lid 20 rotates 90 ° with respect to the rear panel 3, the engaging portion 23 engages with the rear panel 3.

  Further, when the lid 20 rotates with respect to the rear panel 3, the engaging convex portion 12 formed on the rear panel 3 enters the guide groove 25 formed on the lid 20 and is guided by the guide groove 25. Then, the process proceeds in the direction indicated by the arrow E in FIG. Then, when the lid 20 is rotated by 90 °, the engaging convex portion 12 engages with the engaging concave portion 24. As a result, the lid 20 is attached to the rear panel 3. FIG. 5 shows a state where the lid 20 is attached to the rear panel 3 (this state is referred to as an attached state).

  As described above, the separation distance ΔW between the engaging portion 23 and the back surface 21b is set to be equal to or slightly smaller than the thickness of the rear panel 3. For this reason, the engaging force of the engaging portion 23 with respect to the rear panel 3 is strong, so that there is no backlash between the lid 20 and the rear panel 3, and the lid 20 can be prevented from being detached from the rear panel 3. .

  Further, as the lid body 20 rotates, the engagement convex portion 12 relatively moves in the E direction in the guide groove 25 formed so as to be gradually narrowed. In particular, the rotation angle of the lid body 20 is close to 90 °. At this time, the engaging convex portion 12 gets over the inclined surface 27 and engages with the engaging concave portion 24 formed in the protruding portion 26. For this reason, the engaging force between the engaging convex portion 12 and the engaging concave portion 24 is strong, and thus the lid 20 can be reliably attached to the rear panel 3 in the attached state.

  Thus, by attaching the lid 20 to the rear panel 3 using the attachment structure according to the present embodiment, the lid 20 can be simply rotated by inserting the engaging portion 23 into the opening 10. The lid 20 can be attached to the rear panel 3. Further, there is no need for attachment parts other than the rear panel 3 (case 2) and the lid 20, and the number of parts can be reduced as compared with a conventional attachment structure using screws. Furthermore, in the rear panel 3, since it is only necessary to form the opening 10 having the bearing portion 11, the mounting structure can be simplified.

  FIG. 6 shows a state where the above-described electronic device 1 is mounted on the stand 30.

  The stand 30 can be installed horizontally on a base such as a table. However, in order to save the installation space, the electronic device 1 can be installed in a standing state with the stand 30 mounted. Has been done. In the embodiment shown in FIG. 6, the rear panel 3 is located on the front surface, the upper surface 7 is located on the right side, the bottom plate 9 is located on the left side, the right side surface 4 is located on the lower side, and the left side surface 5 is located on the upper side. (Hereinafter, this mode is referred to as a first mounting mode).

  Here, attention is paid to the shape of the electronic device 1. As shown in FIGS. 4A and 6A, the right side surface 4 and the left side surface 5 of the case 2 are formed to be inclined inward by an angle θ with respect to a direction perpendicular to the upper surface 7 ( This angle is called the inclination angle θ). This inclination angle θ is provided in order to surely and easily perform die cutting when the case 2 is molded. The specific inclination angle θ is appropriately set depending on the shape of the case 2 and the resin material to be used. In the present embodiment, θ = 3 °.

  8 and 9 are enlarged views of the stand 30. FIG. FIG. 8 is a perspective view of the stand 30, and FIG. 9 is a front view of the stand 30. The stand 30 is a resin molded product, and has a structure in which a base 31, support portions 32A and 32B, a first mounting surface 33A, a second mounting surface 33B, ribs 34A and 34B, and the like are integrally formed.

  The base 31 has an area that can ensure the stability that the electronic device 1 does not fall when the electronic device 1 is supported. An outer peripheral rib 38 and a reinforcing rib 39 for reinforcing the base 31 are formed on the back surface of the base 31. In addition, rubber feet 36 (shown by alternate long and short dash lines) functioning as slip stoppers are disposed at the four corners of the base 31.

  Rubber foot ribs 37 are formed at positions where the rubber feet 36 of the base 31 are disposed. The rubber foot ribs 37 are connected so as to be substantially perpendicular to the outer peripheral ribs 38 (connection positions are indicated by arrows B in FIG. 8B). By connecting the rubber foot ribs 37 to the outer peripheral ribs 38 in this way, the thickness at the connection position B can be reduced.

  Generally, when the thickness at the rib connection position is increased, a scale or a depression may be generated on the surface of the molded product after resin molding. However, by adopting the connection form as in the present embodiment, the thickness of the connection position B can be reduced, and after the formation of the stand 30, scales and depressions are generated on the surface of the four corner positions of the base 31. Can be suppressed.

  The pair of support portions 32 </ b> A and 32 </ b> B are erected on the base 31 at a separation distance that can support the electronic device 1 therebetween. A plurality of ribs 34A and 34B extending vertically are formed on the inner walls of the support portions 32A and 32B.

  The ribs 34 </ b> A and 34 </ b> B support the electronic device 1 by engaging with the electronic device 1 that is inclined and supported as described later. At this time, since the formation positions of the plurality of ribs 34A and 34B are separated from each other, the electronic device 1 can be supported without backlash even if the outer surface of the electronic device 1 is slightly uneven.

  Here, attention is paid to the shape of the bottom surface located between the pair of support portions 32A and 32B. As shown in FIG. 9 in an enlarged manner, the bottom surface located between the pair of support portions 32A and 32B is constituted by a first mounting surface 33A and a second mounting surface 33B.

  The first mounting surface 33A is an inclined surface that rises from the right end in the drawing toward the center position. The second mounting surface 33B is an inclined surface that rises from the left end in the drawing toward the center position. Therefore, the first mounting surface 33A and the second mounting surface 33B have a mountain shape when viewed from the front. Further, the inclination angle of the first mounting surface 33A and the inclination angle of the second mounting surface 33B are both set to the same angle as the inclination angle θ of the right side surface 4 and the left side surface 5 of the electronic device 1 described above. .

  FIG. 10A is an enlarged view showing particularly the vicinity of the first and second mounting surfaces 33A and 33B in a state where the electronic device 1 is mounted on the stand 30 according to the first mounting mode. As shown in the figure, the first mounting surface 33A and the second mounting surface 33B have a mountain shape with the center position as a vertex. For this reason, the electronic device 1 having the right side surface 4 with the inclination angle θ is mounted on the stand 30 in a substantially vertical posture by the right side surface 4 coming into contact with the second mounting surface 33B.

  In the mounting according to the first mounting mode, the first mounting surface 33A and the right side surface 4 are separated from each other. However, the right side surface 4 abuts on the second mounting surface 33B, and due to the inclination of the second mounting surface 33B and the right side surface 4, a force acts on the electronic device 1 in the direction indicated by the arrow G1 in the figure. Therefore, the electronic device 1 is supported in a state where the electronic device 1 falls on the support portion 32B. Therefore, even when the right side surface 4 is in contact with only the second mounting surface 33B having a length that is half the distance between the pair of support portions 32A and 32B, the electronic device 1 is supported by the stand 30 without rattling. .

  The bottom plate 9 of the electronic device 1 is provided with rubber feet 13 in the vicinity of the four corner positions. The rubber foot 13 functions as a slip stopper while separating the installation surface and the bottom plate 9 when the electronic device 1 is installed in a plane. The rubber feet 13 are configured to engage with the side surfaces 35A and 35B of the support portions 32A and 32B when the electronic device 1 is mounted on the stand 30. In the first mounting mode shown in FIG. 10 (A), the rubber foot 13 is engaged with the side surface 35B of the support portion 32B.

  Thus, when the electronic device 1 is attached to the stand 30 by engaging the rubber feet 13 with the side surfaces 35A and 35B of the support portions 32A and 32B, the electronic device 1 is illustrated with respect to the stand 30. 6 (B) is restricted from moving in the direction indicated by the arrow X. Thereby, for example, even if a wiring or the like is connected to the electronic device 1 and an unexpected tensile force or the like acts on the wiring, the electronic device 1 can be prevented from being detached from the stand 30.

  FIG. 7 shows a second mounting mode for the stand 30 of the electronic apparatus 1. In the second mounting mode, the rear panel 3 is located on the front surface, the upper surface 7 is located on the left side, the bottom plate 9 is located on the right side, the right side surface 4 is located on the upper side, and the left side surface 5 is located on the lower side. Yes.

  FIG. 10B is an enlarged view showing particularly the vicinity of the first and second mounting surfaces 33A and 33B in a state where the electronic device 1 is mounted on the stand 30 according to the second mounting mode. In the second mounting mode, the electronic device 1 is mounted on the stand 30 in a substantially vertical posture when the left side surface 5 abuts on the first mounting surface 33A.

  In the mounting according to the second mounting mode, the second mounting surface 33B and the left side surface 5 are in a separated state. However, the left side surface 5 abuts on the first mounting surface 33A, and a force acts on the electronic device 1 in the direction indicated by the arrow G2 in the drawing due to the inclination of the first mounting surface 33A and the left side surface 5. Therefore, the electronic device 1 is supported in a state where the electronic device 1 falls on the support portion 32A. Therefore, also in the second mounting mode, the electronic device 1 is supported by the stand 30 without rattling.

  FIG. 11 shows a third mounting mode for the stand 30 of the electronic apparatus 1. In the third mounting mode, the rear panel 3 is located on the back surface, the upper surface 7 is located on the left side, the bottom plate 9 is located on the right side, the right side surface 4 is located on the lower side, and the left side surface 5 is located on the upper side. Yes.

  In the mounting according to the third mounting mode, the second mounting surface 33B and the right side surface 4 are separated from each other, but the right side surface 4 is in contact with the first mounting surface 33A. Further, since a force acts on the electronic device 1 in the direction indicated by the arrow G2 in FIG. 11A, the electronic device 1 is supported in a state where it falls on the support portion 32A. Therefore, also in the third mounting mode, the electronic device 1 is supported by the stand 30 without rattling.

  FIG. 12 shows a fourth mounting mode with respect to the stand 30 of the electronic apparatus 1. In the fourth mounting mode, the rear panel 3 is located on the back surface, the upper surface 7 is located on the right side, the bottom plate 9 is located on the left side, the right side surface 4 is located on the upper side, and the left side surface 5 is located on the lower side. Yes.

  In the mounting according to the fourth mounting mode, the first mounting surface 33A and the left side surface 5 are separated from each other, but the left side surface 5 is in contact with the second mounting surface 33B. In addition, since a force acts on the electronic device 1 in the direction indicated by the arrow G1 in FIG. 12A, the electronic device 1 is supported in a state where it falls on the support portion 32B. Therefore, also in the fourth mounting mode, the electronic device 1 is supported by the stand 30 without rattling.

  As described above, there are first to fourth mounting modes for mounting the electronic device 1 to the stand 30. With the configuration of the present embodiment, the electronic device 1 can be reliably mounted and supported on the stand 30 in any mounting manner, and thus the degree of freedom of installation of the electronic device 1 can be increased.

  The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific embodiments described above, and various modifications are possible within the scope of the gist of the present invention described in the claims.
