Conversely, by inserting the inclined detachable panel 9 into the panel mounting recess 15, the hinge shaft 45 fits into the hinge bearing 47, and the detachable panel 9 can be attached to the main body panel 7.

  Next, the configuration of the engaging portion 43 will be described. The engaging portion 43 is disposed at the upper center of the detachable panel 9 and is configured to hold the mounting posture by engaging the detachable panel 9 and the main body panel 7 in the mounting posture. Schematically, the engaging portion 43 includes an engaging protrusion 51 that protrudes from the main body panel 7 toward the detachable panel 9 and a pair of hooks 61 that protrude from the detachable panel 9 toward the main body panel 7. The hook 61 sandwiches the engaging protrusion 51.

  FIG. 9A and FIG. 9B are a perspective view and a front view of the engaging protrusion 51. The engaging protrusion 51 is disposed at the upper center of the rear side wall surface of the panel mounting recess 15 and protrudes forward. From the tip of the engaging protrusion 51, the protrusion-side claw 53 protrudes in the right direction. Further, the engaging protrusion 51 has protrusion-side inclined portions 55 on both side surfaces as shown in the drawing, which will be described later together with the hook-side inclined portion 71 of the hook 61.

  Next, the configuration of the hook 61 will be described. As shown in FIG. 6, the pair of hooks 61 are provided in the clamper 63. The clamper 63 includes a base plate 65, and a pair of hooks 61 protrude from the base plate 65. The pair of hooks 61 are provided with an interval of a size suitable for sandwiching the engaging protrusion 51 in the lateral direction. Each hook 61 includes a hook-side claw portion 69 that protrudes toward the mating hook portion 61 at the tip. The clamper 63 is incorporated into the detachable panel 9 by being sandwiched between the detachable panel front cover 33 and the detachable panel rear cover 35 together with the operation button 23.

  FIG. 10 is an enlarged view of a portion of the clamper 63 on the back surface of the detachable panel 9. A hook recess 67 is provided in the upper part of the back surface of the detachable panel 9, and the clamper 63 is located in the hook recess 67. The pair of hooks 61 protrudes forward from the bottom of the hook recess 67, and thereby protrudes toward the main body panel 7. In addition, the front-end | tip of the hook 61 and the back surface of the detachable panel 9 are substantially the same height in the front-back direction.

  Each hook 61 has a hook-side inclined portion 71 on the side in contact with the engagement protrusion 51 as shown in the figure. The hook-side inclined portion 71 is inclined with respect to the direction in which the hook 61 is sandwiched, and the direction of inclination is set so that it goes outward as it goes upward, that is, the gap between the two hooks 61 becomes larger as it goes upward. Has been. And as shown in FIG. 9, corresponding to the hook side inclined part 71, the engagement protrusion 51 also has the protrusion side inclined part 55 on either side. The protrusion-side inclined portions 55 are both side surfaces of the engaging protrusion 51 and come into contact with the hook-side inclined portion 71 when engaged. The angle and direction of the protrusion-side inclined portion 55 are the same as those of the hook-side inclined portion 71.

  Here, the sandwiching direction by the hook 61 is the lateral direction, the support direction by the support portion 41 is the vertical direction, and the sandwiching direction and the support direction intersect at a right angle. The hook-side inclined portion 71 and the projection-side inclined portion 55 are also inclined with respect to the support direction by being inclined with respect to the sandwiching direction.

  Next, a state when the above-described engaging protrusion 51 and the pair of hooks 61 are engaged will be described. 11 is a cross-sectional view of the front view of FIG. 4 taken along line AA, FIG. 12 is an enlarged view of the engaging portion 43 of FIG. 11, and FIG. It is a longitudinal cross-sectional view.

  As illustrated, in the engaged state, the pair of hooks 61 sandwich the engaging protrusions 51 from both sides. The gap between the hooks 61 is set slightly smaller than the width of the engaging protrusion 51. Thereby, the hook 61 in the engaged state is elastically bent and deformed outward, and the pair of hooks 61 press the engagement protrusions 51 from both sides with an elastic force generated by the elastic deformation. With this pressing force, the lateral movement of the detachable panel 9 is restricted.

  Furthermore, in the present embodiment, as described below, the vertical movement of the detachable panel 9 is also restricted by the pressing force of the hook 61. In the engaged state, the hook-side inclined portion 71 of the hook 61 and the protrusion-side inclined portion 55 of the engaging protrusion 51 are in contact with each other, so that the hook-side inclined portion 71 presses the protrusion-side inclined portion 55 by elastic deformation of the hook 61. Each hook 61 receives a reaction force in an oblique direction from the engaging projection 51 by pressing between the inclined surfaces. A part of this reaction force acts on the hook 61 as a downward force F as shown in FIG. 13 and pushes down the detachable panel 9. On the other hand, the support direction of the hinge which is the support part 41 of the detachable panel 9 is upward, and is opposite to the force F. Accordingly, the detachable panel 9 is pushed down from the upper side and supported from the lower side, and the vertical movement of the detachable panel 9 is restricted.

  The detachable panel 9 is also restricted from moving in the front-rear direction as follows. At the time of engagement, the hook 61 advances from the front to the rear and engages with the engagement protrusion 51. At this time, the hook side claw portion 69 of the hook 61 gets over the projection side claw portion 53 of the engagement projection 51. As shown in FIG. 12, the hook-side claw portion 69 and the projection-side claw portion 53 continue to contact even when placed in the engaged state. The height in the front-rear direction of the hook 61 and the engagement protrusion 53 is set so that the contact state between the claws can be obtained.

  Thus, in the present embodiment, in a state where the detachable panel 9 is held in the mounting posture, the hook side claw portion 69 is in a position over the projection side claw portion 53, that is, the projection side claw portion. In a state where 53 is positioned closer to the base plate 65 than the hook side claw portion 69, the hook side claw portion 69 is in contact with the projection side claw portion 53. As a result, a force is generated in the direction in which the engaging protrusion 51 pulls the hook 61, and the movement of the detachable panel 9 in the front-rear direction is restricted.

  The above-described restriction of movement in the front-rear direction will be further described. Suppose that the hook 61 or the engaging protrusion 51 is provided higher than in the present embodiment, and the hook-side claw portion 69 is separated from the protrusion-side claw portion 53 in the engaged state. In this case, since the movement of the hook claw portion 69 is not restricted by the projection side claw portion 53, the front and rear movement of the hook 61 is allowed, and the upper end portion of the detachable panel 9 may be rattled in the front-rear direction. On the other hand, in the present embodiment, as described above, the contact between the hook side claw portion 69 and the projection side claw portion 53 is maintained even after the engagement, thereby restricting the movement of the detachable panel 9 in the front-rear direction. And rattling is prevented.

  Next, the material of the constituent elements of the engaging portion 43 will be described. The clamper 63, that is, the hook 61 is made of an elastic material, and specifically, polyacetal resin is used. The polyacetal resin is excellent in durability, slidability and heat resistance, and is flexible. In the present embodiment, an elastic material is used in order to obtain a reliable engagement state using the elastic deformation of the hook 61. On the other hand, the engagement protrusion 51 may not be an elastic body. Therefore, the engagement protrusion 51 is integrally formed with the main body panel 7, and a general resin material is used as a material, for example, a polycarbonate resin and an ABC resin.

  In the above, the support part 41 and the engaging part 43 in the attachment structure of the detachable panel 9 were demonstrated in detail. The other configuration related to the attachment of the detachable panel 9 will be described. A rotation operation portion 81 is provided at the center of the upper surface of the detachable panel 9. The rotation operation portion 81 is located in the vicinity of the engaging portion 43, and more specifically, is located at the same position in the lateral direction as the engaging portion 43 and above the engaging portion 43.

  The rotation operation part 81 is a part operated to rotate the detachable panel 9 around the rotation axis of the hinge of the support portion 41. The user puts his / her finger on the rotation operation part 81 and rotates the detachable panel 9. The rotation operation portion 81 is provided with a small upward projection 83 so that the user can easily operate.

  Further, the main body panel 7 has a notch 87 in the upper wall 85 of the panel mounting recess 15. The notch 87 is provided at a position corresponding to the rotation operation part 81 and exposes the rotation operation part 81.

  With such a configuration, the detachable panel 9 can be rotated using the rotation operation part 81 without interference between the user's finger placed on the rotation operation part 81 and the main body panel 7. Further, the structure for the rotation operation is realized by the rotation operation part 81 on the upper surface of the detachable panel 9 and the notch portion 87 of the main body panel 7, and therefore it is unnecessary to provide a special operation member, It is not necessary to provide a large space for the operation member, and the rotation operation can be performed with a compact structure.

  The upper wall portion 85 of the panel mounting recess 15 is a plate-like portion extending in the lateral direction. The disc insertion slot 13 is located above the upper wall portion 85, and the upper surface of the upper wall portion 85 also has a function of guiding the disc to be inserted.

  Furthermore, as shown in FIG. 14, an illumination unit 89 is provided on the upper surface of the upper wall portion 85. The illumination unit 89 is made of a translucent resin and transmits illumination light emitted from a light source provided inside the main body panel 7, thereby brightening the illumination unit 89.

  The illumination part 89 is provided on the upper surface of the upper wall part 85 and at a position adjacent to the notch part 87. More specifically, the illuminating unit 89 is provided on the rear side of the notch 87, at a position spaced from the edge of the notch 87, and below the disc insertion slot 13. doing. With this arrangement, the illumination unit 89 guides the position of the rotation operation portion 81 and also guides the position of the disc insertion slot 13.

  In addition, buffer members 91 are attached near both ends of the upper portion of the panel mounting recess 15. The buffer member 91 is, for example, rubber. The buffer member 91 can further contribute to preventing the detachable panel 9 from rattling.

  The configuration of the in-vehicle electronic device 1 according to the embodiment of the present invention has been described above. Next, the operation of the in-vehicle electronic device 1 will be described. Here, the operation for attaching the detachable panel 9 to the main body panel 7 and the operation for removing the detachable panel 9 from the main body panel 7 will be described in order.

  At the time of attachment, the detachable panel 9 is inserted toward the panel mounting recess 15 of the main body panel 7 in a posture inclined to the front side. As a result, the hinge shafts 45 provided at the lower ends of the panel mounting recesses 15 of the main body panel 7 pass through the notches 49 of the hinge bearings 47 at the lower ends of the detachable panel 9 and fit into the hinge bearings 47. In this way, the detachable panel 9 is in the inclined posture of FIG. At substantially the same time as the hinge shaft 45 and the hinge bearing 47 are connected, the upper end of the detachable panel 9 is moved rearward, and the detachable panel 9 is rotated about the hinge shaft 45 from the inclined posture to the mounting posture. When the detachable panel 9 reaches the position of the mounting posture, the pair of hooks 61 of the engaging portion 45 sandwich the engaging protrusion 51. At this time, the pair of hooks 61 are pushed in the lateral direction by the engaging portion 45 and elastically bent and deformed. In the right hook 61, the hook side claw portion 69 gets over the projection side claw portion 53 of the engaging projection 51. However, as described above, the hook-side claw portion 69 rides over the projection-side claw portion 53, but does not leave the projection-side claw portion 53 and stops at a position where it remains in contact with the projection-side claw portion 53.

  As described above, the engaging portion 43 engages the detachable panel 9 and the main body panel 7 and holds the detachable panel 9 in the mounting posture. In this state, as described in detail above, the movement of the detachable panel 9 in the lateral direction is restricted by the sandwiching of the pair of hooks 61. In addition, since the hook 61 and the engagement protrusion 51 are provided with inclined portions, a downward force (that is, a force opposite to the support direction) from the engagement protrusion 51 to the hook 61 as the hook 61 is elastically deformed. ) Works, and the vertical movement of the detachable panel 9 is also restricted by this force. Further, in the mounted state, the hook-side claw portion 69 is in contact with the projection-side claw portion 53 at a position over the projection-side claw portion 53, thereby restricting the movement of the detachable panel 9 in the front-rear direction. . Thus, according to the present embodiment, rattling of the detachable panel 9 can be suppressed.

  The operation when the detachable panel 9 is mounted has been described above. In the above operation, the detachable panel 9 is attached to the main body panel 7 by inserting the detachable panel 9 into the panel mounting recess 15 and turning it. Thus, the detachable panel 9 can be easily attached by a series of operations.

  Next, an operation for removing the detachable panel 9 will be described. In this case, the upper part of the attachable detachable panel 9 is moved forward. Thereby, in the engaging part 43, the hook 61 moves forward while elastically deforming, disengages from the engaging protrusion 51, and the engaged state is released. Then, the detachable panel 9 rotates about the hinge shaft 45 and tilts to the front side to be in an inclined posture. When the detachable panel 9 is moved further forward, the hinge shaft 45 passes through the notches 49 of the hinge bearings 47 on both sides, the hinge coupling is released, and the detachable panel 9 is pulled out from the panel mounting recess 15. In this way, the detachable panel 9 is removed from the main body panel 7.

  In the above detaching operation, the detachable panel 9 is rotated and removed from the main body panel 7 by moving the upper part of the detachable panel 9 forward. In this manner, the detachable panel 9 can be easily removed by a series of operations.

  In addition, it is suitable for a user to pinch the center part of the detachable panel 9 in said attachment and removal. Typically, a thumb and an index finger are used, and the thumb is placed on the rotation operation portion 81 on the upper surface, and the lower part of the panel is supported by the index finger. In this way, the detachable panel 9 can be attached to and detached from the main body panel 7 with a simple operation as described above. In addition, since the notch 87 is provided in the main body panel 7, interference between the user's finger and the main body panel 7 can be avoided, and there is no need to change the position of the finger during the attachment / detachment process (that is, no need for changing work). This also facilitates the operation.

  The detaching operation of the detachable panel 9 has been described above. Next, a modification of the present embodiment will be described.
