Japanese Patent Laid-Open No. 2003-127791

  By the way, when a device such as an audio device is attached to an instrument panel in a vehicle interior where the vibration environment is poor, the bracket is required to have vibration durability so that vehicle vibration is not transmitted to the device as much as possible. The shape and material of the bracket such as the thickness and size of the bracket are determined so as to satisfy this vibration durability.

  On the other hand, the equipment exposed from the instrument panel in the passenger compartment was subjected to a force greater than the specified size in order to minimize the impact on the occupant even when the occupant hits the equipment in the event of a vehicle collision. Sometimes it is required to be fixed so as to retract inward of the instrument panel. For this reason, it is preferable that the bracket itself for fixing the device has a structure capable of absorbing the impact.

  However, if the bracket itself has the necessary shock absorbing performance depending on the plate thickness, shape, etc., the vibration durability performance is impaired, and the conventional L-shaped bracket conflicts with the shock absorption performance and vibration durability performance. It was difficult to satisfy the two performances.

  The present invention has been made in view of such circumstances, and provides a bracket capable of obtaining necessary vibration durability while ensuring necessary shock absorption performance.

  A bracket according to the present invention is a bracket to be fixed between a first object and a second object, and includes a first attachment plate portion to be fixed to the first object, and the first attachment. A second mounting plate portion which is arranged substantially perpendicular to the first mounting plate portion without intersecting the plate portion and its extended surface and is to be fixed to the second object; and the first mounting plate portion And a corner plate portion connected to each of the second mounting plate portions at an obtuse angle, the corner plate portion including a first portion connected to a side of the first mounting plate portion, and the second mounting plate portion. And the first part and the second part are connected so as to protrude in a direction away from the region where the first mounting plate part and the second mounting plate part face. And the first portion of the corner plate portion and the corner plate portion A configuration having a cut and raised plate portion formed by raised off the two parts together in the edge end direction.

  With such a configuration, since the cut-and-raised plate portion that acts as a rib is formed on the corner plate portion connected to the first mounting plate portion and the second mounting plate portion, the rigidity of the entire bracket can be increased. In addition, since the corner plate portion is constituted by the first portion and the second portion that are connected so as to protrude in a direction away from the region where the first attachment plate portion and the second attachment plate portion face, the first object When an impact force toward the corner plate portion along the first mounting plate portion is generated by applying an impact force to the second mounting plate portion, or when an impact force is applied to the second object, the second mounting plate portion is applied to the second mounting plate portion. When an impact force toward the corner plate portion is generated along the corner plate portion, the cut-and-raised plate portion is the first portion of the corner plate portion at the boundary line between the first portion and the second portion. Each can be easily broken at a boundary line between a portion corresponding to the portion and a portion corresponding to the second portion of the corner plate portion.

  In the bracket according to the present invention, the corner plate portion includes the first attachment plate portion and the second attachment plate so that an angle with respect to the first attachment plate portion and an angle with respect to the second attachment plate portion are substantially the same.

The joint part with the second mounting plate part and the fixing part to the second object in the second mounting plate part may be arranged on the same plane.

  With such a configuration, when an impact force is applied to the corner plate portion along the first mounting plate portion by applying an impact force to the first object, or an impact force is applied to the second object. Thus, when an impact force directed toward the corner plate portion along the second mounting plate portion is generated, the impact force and the reaction force are cut up and acted effectively from both sides of the plate portion.

  Further, in the bracket according to the present invention, the edge of the portion corresponding to the first portion of the corner plate portion of the cut and raised plate portion and the second portion of the corner plate portion of the cut and raised plate portion correspond to the second portion. The edges of the portions may be broken lines and joined.

  With such a configuration, the force propagating along the edge corresponding to the first portion of the corner plate portion of the cut and raised plate portion and the force propagating along the edge corresponding to the second portion of the corner plate portion of the cut and raised plate portion are generated. The portion of the cut-and-raised plate portion corresponding to the first portion of the corner plate portion and the second portion thereof are caused to butt against the joining line between the first portion and the second portion in a concentrated manner. It can be prevented that the corresponding portion is stretched and the cut and raised plate portion is difficult to break.

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

  A bracket according to an embodiment of the present invention is configured as shown in FIGS. This bracket is used, for example, to fix an in-vehicle device (for example, an audio device) to a frame in the instrument panel. 1 is a perspective view showing a state in which a device is fixed to a frame in an instrument panel using a bracket, FIG. 2 is a perspective view showing the bracket, and FIG. 3 shows the bracket. FIG. 4 is a front view of the bracket viewed from the front of one mounting plate, and FIG. 5 is a front view of the bracket viewed from the front of the other mounting plate.

  As shown in FIG. 1, the device 200 is fixed to the frames 300a and 300b by brackets 10a and 10b fixed to both side surfaces thereof. These brackets 10a and 10b are formed by pressing one sheet metal. FIG. 1 shows only the entire configuration of one bracket 10a, but the structure is the same as that of the bracket 10a except that the other bracket 10b is also opposite to the left and right. Therefore, hereinafter, one bracket 10a will be described.

  The bracket 10a includes a first attachment plate portion 11 fixed to the device 200 (first object), a second attachment plate portion 12 fixed to the frame 300a (second object), and a first attachment plate portion. 11 and a second mounting plate portion 12 having a corner plate portion 13 connected with an obtuse angle. Further, referring to FIGS. 2 to 5 together with FIG. 1, the first mounting plate portion 11 and the second mounting plate portion 12 are configured so that the other mounting plate portion does not cross the other mounting plate portion and its extension surface. It arrange | positions so that it may become substantially right angle with respect to a part (refer especially FIG. 3). The corner plate portion 13 includes a first portion 131 connected to the first mounting plate portion 11 and a second portion 132 connected to the second mounting plate portion 12, and the first portion 131 and the second portion 132 are connected to each other. The first mounting plate portion 11 and the second mounting plate portion 12 are connected so as to be convex in a direction away from the region E (see FIG. 3) where the first mounting plate portion 12 and the second mounting plate portion 12 face.

  The first plate 131 and the second plate 132 are both cut and raised in the edge direction in the vicinity of both edge portions of the corner plate portion 13 to form cut-and-raised plate portions 14a and 14b. As a result of the cut-and-raised plate portions 14a and 14b being formed in the vicinity of both edges of the corner plate portion 13, the first mounting plate portion 11 and the second mounting plate are disposed between the two raised and raised plate portions 14a and 14b. A space 133 sandwiched between the portions 12 is formed. One cut-and-raised plate portion 14 a has a portion 141 corresponding to the first portion 131 of the corner plate portion 13 and a portion 142 corresponding to the second portion 132 toward one edge of the corner plate portion 13. It is connected to be convex. Similarly, the other cut-and-raised plate portion 14 b has a portion 141 corresponding to the first portion 131 of the corner plate portion 13 and a portion 142 corresponding to the second portion 132 on the opposite side of the corner plate portion 13. It is connected so as to be convex toward the edge. Accordingly, the two cut-and-raised plate portions 14a and 14b have convex shapes that protrude in opposite directions.

The first mounting plate portion 11 is formed with four mounting holes 111a, 111b, 112a, 112b through which bolts for fixing to the device 200 pass. As shown in FIG. 4, one of the two mounting holes 111a and 112a passes through the joint portion P1a of the one cut-and-raised plate portion 14a with the first mounting plate portion 11, and passes through the first mounting plate portion 11 and the corner. It arranges on the straight line L1a orthogonal to the boundary line _L11-13 with the board part 13 (1st part 131). The other two mounting holes 111b and 112b pass through the joint portion P1b of the other cut-and-raised plate portion 14b with the first mounting plate portion 11, and pass through the first mounting plate portion 11 and the corner plate portion 13 (first portion). They are arranged on a straight line L1b perpendicular to the boundary line L _11-13 with 131). As a result, when an impact force is applied to the device 200 and an impact force toward the corner plate portion 13 along the first mounting plate portion 11 is generated via the bolt, the impact force is effectively transferred to each cut-and-raised plate. It comes to act on the roots of the portions 14a and 14b (joined portions P1a and P1b with the first mounting plate portion 11).

The second mounting plate 12 is formed with two mounting holes 121a and 121b through which bolts for fixing to the frame 300a pass. Then, as shown in FIG. 5, one attachment hole 121a passes through a joint portion P2a of one cut-and-raised plate portion 14a with the second attachment plate portion 12 and passes through the second attachment plate portion 12 and the corner plate portion 13 ( It is arranged on a straight line L2a orthogonal to the boundary line _L12-13 with the second portion 132). The other mounting hole 121b passes through the joint portion P2b of the other cut-and-raised plate portion 14b with the second mounting plate portion 12, and is connected to the second mounting plate portion 12 and the corner plate portion 13 (second portion 132). They are arranged on a straight line L2b perpendicular to the boundary line L _12-13. Thereby, when the reaction force from the frame 300a is applied due to the impact force applied to the device 200, a force directed toward the corner plate portion 13 along the second mounting plate portion 12 is generated via the bolt. The force effectively acts on the roots of the cut-and-raised plate portions 14a and 14b (joined portions P2a and P2b with the second mounting plate portion 12).

  A straight line L1a (see FIG. 4) on which the attachment holes 111a and 112a formed in the first attachment plate portion 11 and the joining portion P1a of the cut and raised plate portion 14a with the first attachment plate portion 11 are arranged, and a second attachment plate. A straight line L2a (see FIG. 5) in which a joint portion P2a of the mounting hole 121a formed in the portion 12 and the second mounting plate portion 12 of the cut and raised plate portion 14a is arranged, and a first mounting plate of the cut and raised plate portion 14a. A straight line connecting the joint part P1a with the part 11 and the joint part P2a with the second mounting plate part 12 is included on the same plane. That is, the attachment site | part of the attachment holes 111a and 112a formed in the 1st attachment plate part 11, the attachment hole 121a formed in the 2nd attachment plate part 12, and the 1st attachment plate part 11 of the cut-and-raised plate part 14a P1a and the joining part P2a with the 2nd attachment board part 12 are arranged on the same plane. Similarly, the other mounting holes 111b and 112b formed in the first mounting plate portion 11, the other mounting hole 121b formed in the second mounting plate portion 12, and the second cut-and-raised plate portion 14b of the first raising plate portion 14b. The joint part P1b with the first mounting plate part 11 and the joint part P2b with the second mounting plate part 12 are arranged on the same plane.

  Thereby, when an impact force is applied to the corner plate portion 13 (first portion 131) along the first mounting plate portion 11 due to the impact force applied to the device 200, the impact force and the second mounting plate The reaction force toward the corner plate portion 13 (second portion 131) along the portion 12 is cut and raised, and effectively acts on the bases on both sides of the plate portions 14a and 14b.

  6 and 7 are enlarged perspective views showing the vicinity of one cut and raised plate portion 14a of the bracket 10a. 6 and 7 show the vicinity of one cut-and-raised plate portion 14a, the vicinity of the other cut-and-raised plate portion 14b is similarly configured.

  As shown enlarged in FIG. 6 together with FIGS. 2 to 5, at the boundary portion between the first portion 131 and the second portion 132 on the edge of the corner plate portion 13 on the side where the one raised plate portion 14 a is formed. A notch 134a is formed. Similarly, on the side where the other cut-and-raised plate portion 14 b is formed, a notch portion 134 b is formed at the boundary portion between the first portion 131 and the second portion 132 on the edge of the corner plate portion 13. The cutout bottom corners of these cutouts 134a and 134b may be round or cornered.

Further, as shown in FIG. 6, the boundary line L _131-141 between the first portion 131 of the corner plate portion 13 and the cut and raised plate portion 14a, the second portion 132 of the corner plate portion 13 and the cut and raised plate portion 14a, Boundary line L _132-142 and a boundary line L between the portion 141 corresponding to the first portion 131 of the corner plate portion 13 and the portion 142 corresponding to the second plate portion 132 of the corner plate portion 13 in the cut and raised plate portion 14a. _A hole 135a is formed in the root portion of the cut and raised plate portion 14a where _141-142 concentrates. Further, the other cut-and-raised plate portion 14 is also formed with a hole 135b at the same root portion. The shape of these holes 135a and 135b may be round or angular.

The edge line LE ₁₄₁ of the portion 141 corresponding to the first portion 131 of the corner plate portion 13 of the cut and raised plate portion 14a rises at a predetermined acute angle and forms a broken line. Further, the edge line LE ₁₄₂ of the portion 142 corresponding to the second portion 132 of the corner plate portion 13 of the cut and raised plate portion 14a rises at a predetermined acute angle and forms a broken line.

Further, as shown in an enlarged view in FIG. 7, the first mounting plate portion 11 (edge line LE ₁₁ ) and the corner plate portion 13 (edge line LE ₁₃₁ of the first portion ₁₃₁ ) have an obtuse angle, for example, substantially 150. They are connected at an angle of 30 degrees (complement angle: 30 degrees). The second mounting plate portion 12 (edge line LE ₁₂ ) and the corner plate portion 13 (edge line LE ₁₃₂ of the second portion ₁₃₂ ) have the same obtuse angle, for example, an angle of substantially 150 degrees (complement angle: 30 degrees). Are connected. Further, the first portion 131 and the second portion 132 of the corner plate portion 13 are connected with an obtuse angle, for example, an angle of substantially 150 degrees (complement angle: 30 degrees). The cut and raised plate portion 14 a includes a boundary line L _141-142 between a portion 141 corresponding to the first portion 131 of the corner plate portion 13 and a portion 142 corresponding to the second portion 132 of the corner plate portion 13, and the corner plate portion 13. The boundary line L _131-132 between the first portion 131 and the second portion 132 is formed to be substantially perpendicular. Thus, the cut-and-raised plate portion 14a is in a state of reliably standing up from the corner plate portion 13 that is bent at the boundary line L _131-132 between the first portion 131 and the second portion 132.

A boundary line L _11-13 between the first mounting plate portion 11 and the corner plate portion 13 (first portion 131), and a boundary line between the cut and raised plate portion 14a (portion 141) and the first portion 131 of the corner plate portion 13 L _131-141 is formed with an acute angle, for example, an angle of substantially 60 degrees. A boundary line L _12-13 between the second mounting plate portion 12 and the corner plate portion 13 (second portion 132), and a boundary line between the raised plate portion 14a (portion 142) and the second portion 132 of the corner plate portion 13 L _132-142 is formed with the same acute angle, for example, an angle of substantially 60 degrees.

According to the bracket 10a (10b) having the structure as described above, the pair of cut-and-raised plate portions 14a and 14b acting as ribs on the corner plate portion 13 connected to the first attachment plate portion 11 and the second attachment plate portion 12 are provided. Since it is formed, the rigidity of the bracket 10a (10b) as a whole can be increased. In particular, a boundary line L _11-13 between the first mounting plate portion 11 and the corner plate portion 13, and a boundary line L 131 _-141 between the cut and raised plate portion 14 a (part 141) and the first portion 131 of the corner plate portion 13, the angle between the further second attachment plate portion 12 and the corner plate section 13 and the boundary line L _12-13 of the (second portion 132), cut and raised plate section 14a (portion 142) and the corner plate section 13 first Since each of the angles between the boundary portion L _132-142 and the two portions 132 is generally based on 60 degrees capable of keeping the strength high (see FIG. 7), higher rigidity is obtained. Can do.

  Therefore, such a bracket 10a (10b) can maintain a relatively high vibration durability performance. As a result, the device 200 (see FIG. 1) fixed to the frames 300a and 300b by the brackets 10a and 10b is relatively difficult to transmit vibrations generated when traveling on a general road surface when the vehicle is traveling.

  When a direction force F (impact force) perpendicular to the frame 300a acts on the device 200 fixed to the frame 300a (300b) by such a bracket 10a (10b), as shown in FIG. 8, the first mounting plate The bracket 10a (10b) is shown in FIG. 9 by the force F toward the corner plate 13 along the portion 11 and the reaction force F ′ toward the corner plate 13 along the second mounting plate 12. Further, as shown in FIG. 11 and further enlarged as shown in FIG. 10 and as shown in FIG.

The corner plate portion 13 of the bracket 10a (10b) is bent at the boundary line L _131-132 between the first portion 131 and the second portion 132 (see FIG. 3 and FIG. 6). Since the boundary line L _131-132 becomes a press mark formed during press working, it is particularly easy to bend at the boundary. Further, the cut-and-raised plate portions 14 a and 14 b formed by cutting and raising the first portion 131 and the second portion 132 of the corner plate portion 13 are also the portion 141 and the corner plate corresponding to the first portion 131 of the corner plate portion 13. a shape which is bent in the boundary boundary L _141-142 of the portion 142 corresponding to the second portion 132 of the part 13, further, then that the boundary line L _141-142 is press marks attached at the time of press working It is particularly easy to bend at the border.

For this reason, the said force F and reaction force F 'act on the base (P1a, P1b, P2a, P2b: refer FIG. 4, FIG. 5) of the both sides of the cut-and-raised board part 14a (14b) of the bracket 10a (10b). As a result, the corner plate portion 13 starts to be folded at the boundary line L _131-132 between the first portion 131 and the second portion 132, and similarly, the cut-and-raised plate portions 14a and 14b are _Bending starts at a boundary line L _141-142 between the portion 141 corresponding to the first portion 131 and the portion 142 corresponding to the second portion 132 of the corner plate portion 13. The entire bracket 10a (10b) is deformed as shown in FIGS. 9 and 10 so as to be induced by the folding operation of the corner plate portion 13 and the cut and raised plate portions 14a and 14b.

When the force F from the first mounting plate portion 11 side and the reaction force F ′ from the second mounting plate portion 12 side act on the bracket 10a (10b) as described above, as shown in FIG. The force propagating along the edge line LE ₁₁ of the plate part ₁₁ and the edge line LE ₁₃₁ of the first part 131 of the corner plate part 13 (see the solid line arrow), the edge line LE ₁₂ and the corner of the second mounting plate part 12 on the opposite side The force propagating along the edge line LE ₁₃₂ of the second portion 132 of the plate portion 13 (see the broken line arrow) is a notch portion 134 a formed at the boundary portion between the first portion 131 and the second portion 132 of the corner plate portion 13. Therefore, the corner plate portion 13 can be more easily broken without stretching at the boundary line L _131-132 between the first portion 131 and the second portion 132.

Further, the first portion 131 of the corner plate portion 13 and the cut-and-raised plate portion 14a (portion 141) pass from the first mounting plate portion 11 side through the joint portion P1a between the raised and raised plate portion 14a and the first mounting plate portion 11. And a force propagating through the boundary line L _131-141 and the second mounting plate portion 12 side through the joint portion P2a between the raised plate portion 14a and the second mounting plate portion 12, and the second of the corner plate portion 13. The force propagating along the boundary line L _132-142 between the portion 132 and the cut and raised plate portion 14a (portion 142) can be concentrated in the hole 135a formed in the root portion of the cut and raised plate portion 14a. For this reason, the cut-and-raised plate portion 14a can be more easily broken without stretching at the boundary line L _141-142 between the portion 141 and the portion 142.

Further, since the edge line LE ₁₄₁ of the portion 141 of the cut-and-raised plate portion 14a is a broken line and the edge line LE ₁₄₂ of the portion ₁₄₂ is a broken line, the force that propagates the edge line LE ₁₄₁ , and the edge line force propagating LE ₁₄₂ is abuts intensively the apex Pt with them the edge line LE ₁₄₁ and LE _142, that is toward the plane of the cut and raised plate section 14a of both of the resultant force, cut and raised plate section 14 It can be prevented that the portion 141 corresponding to the first portion 131 of the corner plate portion 13 and the portion 142 corresponding to the second portion 132 are stretched and the raised plate portion 14a is not easily broken.

  As described above, the bracket 10a (10b) according to the embodiment of the present invention is relatively deformed by the mechanism described above when an impact force (F) is applied from the front of the device 200 (see FIG. 9). It becomes easy to do. Therefore, the bracket 10a (10b) can maintain the vibration durability performance relatively high as described above, and can also maintain the shock absorption performance relatively high.

  Further, the bracket 10a (10b) absorbs an impact by bending and deforming the corner plate portion 13 and the cut-and-raised plate portions 14a and 14b. The return movement of the subsequent device 200 can be minimized.

  Note that the cut-and-raised plate portion 10a (10b) is not limited to two places, and the first attachment plate portion 11 and the second attachment plate portion 12 are attached to an object (device 200, frame 300a, 300b) (attachment hole 111a). , 111b, 112a, 112b, 121a, 121b), one or three or more can be formed.

  As described above, the bracket according to the present invention has an effect that a necessary vibration durability performance can be obtained while ensuring a necessary shock absorbing performance, and is used for fixing an in-vehicle device to a frame. It is useful as a bracket.
