"Effect of mounting structure of in-vehicle device"
Effects of the mounting structure of the ECU 21 will be described with reference to FIGS. 1, 2 and 3. FIG.

According to the embodiment, the size of the bracket 10 is reduced (minimized) by forming the first extending portion 12 and the second extending portion 13 so as to cross each other. Thereby, the bracket 10 can be arranged even in a small space. Furthermore, according to the embodiment, of the pair of brackets 10 having the same external shape, the first extending portion 12 provided on one bracket 10M is inserted into and attached to the first restricting portion 21S of the ECU 21 . Also, the second extending portion 13 provided on the other bracket 10N is inserted into and attached to the second restricting portion 21T of the ECU 21 . Thereby, the ECU 21 and the pair of brackets 10 can be easily attached. As a result, the ECU 21 and the pair of brackets 10 can be easily attached to each other in a small space.

Here, a pair of brackets 10 (one bracket 10M and the other bracket 10N) and an ECU 21 are provided in the vehicle. With such a configuration, the ECU 21 and the pair of brackets 10 can be quickly attached and installed in a predetermined portion of the vehicle. As a result, costs and man-hours can be reduced in vehicle manufacturing.

Furthermore, by using a pair of brackets 10 having the same shape, mass production equipment for assembly with the ECU 21 can be simplified or shared compared to the case of using a pair of brackets having different shapes. The mass production facility is a robot hand that grips the bracket 10 or the like. As a result, the initial cost required for manufacturing the bracket 10 can be reduced.

Furthermore, by using a pair of brackets 10 having the same shape, the mass productivity of the brackets 10 can be improved compared to using a pair of brackets having different shapes. In particular, the bracket 10M on one side and the bracket 10N on the other side are arranged in the same arrangement when rotated 90° in the circumferential direction around the vertical direction. That is, the upper second mounting hole 13a of one bracket 10M and the upper first mounting hole 12a of the other bracket 10N play the same role. As a result, the number of man-hours required for manufacturing the bracket 10 can be reduced.

Furthermore, by using a pair of brackets 10 having the same shape, compared to the case of using a pair of brackets having different shapes, the two types of brackets can be stored separately or the two types of brackets can be stored separately in mass production equipment. You can save the trouble of setting to As a result, the bracket 10 can be easily managed.

According to the embodiment, the first extending portion 12 and the second extending portion 13 of the bracket 10 are provided with a gap therebetween. A first restricting portion 21S (the first proximal restricting portion 21c and the first distal restricting portion 21d) of the ECU 21 is in contact with both ends of the first extending portion 12 of one bracket 10M. The second restricting portion 21T (the second proximal restricting portion 21e and the second distal restricting portion 21f) of the ECU 21 is in contact with both ends of the second extending portion 13 of the other bracket 10N. As a result, the first extending portion 12 of one bracket 10M and the first restricting portion 21S of the ECU 21 are fixed without being displaced. Similarly, the second extending portion 13 of the other bracket 10N and the second restricting portion 21T of the ECU 21 are fixed without being displaced. As a result, the pair of brackets 10 (one bracket 10M and the other bracket 10N) and the ECU 21 can be positioned and fixed.

According to the embodiment, when the first extending portion 12 and the first restricting portion 21S are in contact with each other, the projection 21g provided on one side surface 21b of the ECU 21 and the upper first mounting hole 12a of one bracket 10M are connected. be done. Similarly, when the second extending portion 13 and the second restricting portion 21T are in contact with each other, the projection 21g provided on the other side surface 21b of the ECU 21 and the upper second mounting hole 13a of the other bracket 10N are connected. Thereby, one bracket 10M can be securely attached and fixed to the ECU 21 . Similarly, the other bracket 10N can be reliably attached and fixed to the ECU 21 . As a result, the pair of brackets 10 (one bracket 10M and the other bracket 10N) and the ECU 21 can be positioned and fixed.

According to the embodiment, two first mounting holes 12P (the upper first mounting hole 12a and the lower first mounting hole 12b) of the bracket 10 are provided above and below along the extending direction of the first extending portion 12. . Similarly, two upper and lower second mounting holes 13P (upper second mounting hole 13a and lower second mounting hole 13b) are provided along the extending direction of the second extending portion 13. As shown in FIG. As a result, the vertically aligned upper first mounting holes 12a and lower first mounting holes 12b do not expand more than necessary in the direction intersecting the extension direction (width direction). In other words, the first extending portion 12 of the bracket 10 can be formed based on the lateral width required to open one first mounting hole 12P. Similarly, the vertically aligned upper second mounting holes 13a and lower second mounting holes 13b do not expand more than necessary in the direction intersecting the extension direction (width direction). In other words, the second extending portion 13 of the bracket 10 can be formed based on the width required to open one second mounting hole 13P. As a result, even if the bracket 10 has a plurality of first mounting holes 12P and a plurality of second mounting holes 13P, it is possible to suppress an increase in the external shape.

According to the embodiment, the upper first mounting hole 12a and the lower first mounting hole 12b are formed with different diameters. Similarly, the upper second mounting hole 13a and the lower second mounting hole 13b are formed with different diameters. Accordingly, among the plurality of first mounting holes 12P, the lower first mounting hole 12b having a relatively small diameter is used as a hole for positioning the mounting member 30, and the upper first mounting hole 12a having a relatively large diameter is used. It can be used as a hole for fixing the mounting member 30 . In other words, after inserting the positioning pin 30b of the mounting member 30 into the lower first mounting hole 12b and aligning the positions relatively, the screw 40 is inserted into the upper first mounting hole 12a and screwed into the screw hole 30c of the mounting member 30. can be screwed into the The plurality of second mounting holes 13P have the same effect as the plurality of first mounting holes 12P. As a result, the pair of brackets 10 and mounting member 30 can be easily positioned and fixed.

According to an embodiment, the bracket 10 comprises an edge 14 connecting the first extension 12 and the second extension 13 . Thereby, the deformation of the first extending portion 12 and the second extending portion 13 can be suppressed, and the relative positions of the first extending portion 12 and the second extending portion 13 can be maintained. As a result, the state in which the ECU 21 and the pair of brackets 10 are attached can be maintained.

According to an embodiment, the base 11 is provided with a third mounting hole 11c for mounting. According to such a configuration, the base portion 11 can be made to contribute to the mounting of the in-vehicle device similarly to the first extending portion 12 and the second extending portion 13 .

"Variation"
It should be noted that, in carrying out the present invention, the specific aspects can be changed in various ways.

In the above-described embodiment, the in-vehicle device assumes an electrical configuration such as the ECU 21 as an example. Alternatively, the in-vehicle device may have a mechanical configuration such as a storage container for storing articles.

In the above-described embodiment, the first restricting portion 21S sandwiches only both side end portions of the first extended portion 12 of one bracket 10M between the first proximal restricting portion 21c and the first distal restricting portion 21d. It is assumed to be configured as Instead of this, the first restricting portion 21S has a groove-shaped opening that penetrates vertically, and the first extending portion 12 of one bracket 10M is inserted upward from the lower end of the groove-shaped opening, The first extending portion 12 may be configured to cover the entire surface. The second restricting portion 21T may also be configured to entirely cover the second extending portion 13 of the other bracket 10N by a configuration similar to that of the first restricting portion 21S.
