  By the way, in order to improve fuel consumption, weight reduction of parts mounted on vehicles is being promoted. As one of the methods for that purpose, changing the material from metal to resin has been studied. However, if the resin component has the same shape as the metal component, the strength required for the component may not be ensured. Further, if the resin amount is increased to increase the wall thickness in order to ensure strength, there may be cases where sufficient weight reduction cannot be achieved.

  In this respect, Patent Documents 1 to 3 do not consider any weight reduction of the brake bracket, and there is much room for improvement.

  An object of the present invention is to provide a brake bracket capable of achieving both weight reduction and ensuring strength.

  In order to achieve the above object, one of the inventor's attention is a force acting on the brake bracket when the pedal is depressed.

  Specifically, in the case of a brake pedal in which the above-mentioned arm portion is bent and arranged in a diagonally left direction toward the rear of the vehicle, when the driver steps on the pedal portion, the brake pedal swings around the shaft portion as a fulcrum. However, at this time, the pair of bearing portions in the brake bracket that supports both ends of the shaft portion receive rotational forces in opposite directions. That is, in the case of a right-hand drive vehicle, for example, a force is applied to the bearing portion on the left side of the vehicle body in the direction toward the pedal portion side via the shaft portion, while the bearing portion on the right side of the vehicle body is opposite to the pedal portion via the shaft portion. A force to the side will be applied.

  The present inventor considered the influence of such reaction force in reducing the weight of the brake bracket, and as a result of studying by FEM analysis, the present inventor has completed the present invention capable of solving the above problems.

  That is, the present invention is a brake bracket having a first bearing portion and a second bearing portion for rotatably supporting the first end portion and the second end portion of the shaft portion of the brake pedal, respectively. A first fixing portion and a second fixing portion for fixing the brake bracket to the vehicle body at two points, the first fixing portion being seen from the first bearing portion and the second bearing portion. The second fixed portion is disposed on the first side and is disposed on the second side opposite to the first side when viewed from the first bearing portion and the second bearing portion. The first reinforcing structure is formed in the region connecting the first fixing portion and the second fixing portion, and the second reinforcing structure is formed in the region connecting the second bearing portion and the second fixing portion. is there.

  According to the present invention, the strength of the region between the first bearing portion and the first fixed portion is increased by the first reinforcement structure, and the second bearing portion and the second strength are increased by the second reinforcement structure. The strength of the region that connects the fixed portion is increased. As a result, when the first bearing portion and the second bearing portion are subjected to mutually opposite rotational forces when the brake pedal is depressed, it is possible to achieve both weight reduction and strength securing of the brake bracket. Specifically, when the brake pedal is depressed, a force is applied to the first bearing portion in the direction toward the second side via the shaft portion, and a force is applied to the second bearing portion in the direction toward the first side. In such a case, is the first bearing portion and the second bearing portion pulled from the back side of the direction of the force acting on them (that is, from the restraint point of the first fixing portion and the second fixing portion)? Thus, the strength against the force can be imparted to the brake bracket. Therefore, the strength of the brake bracket can be ensured while reducing the material for the brake bracket as much as possible by appropriately reinforcing the region of the brake bracket that is desirably reinforced from the viewpoint of the direction of the force applied at the time of depression.

  According to a preferred aspect of the present invention, the first reinforcing structure is a first rib group including a plurality of ribs, and the second reinforcing structure is a second rib group including a plurality of ribs. Good.

  With this configuration, the first and second reinforcing structures can be easily formed.

  According to a preferred aspect of the present invention, the first rib group includes a bearing rib group formed below the first bearing portion, and a connection that connects the bearing rib group to a portion that defines the first fixing portion. A rib group, and the second rib group includes a bearing rib group formed below the second bearing portion, and a connecting rib group that connects the bearing rib group to a portion that defines the second fixing portion. It is good to have.

  According to such a configuration, the first bearing part and the second bearing part that receive force from the shaft part when stepped on are reinforced by the bearing rib groups, and between the bearing rib groups and the restraint points. Can be reinforced.

  According to a preferred aspect of the present invention, the brake bracket further includes at least one rib connecting between the bearing rib group of the first rib group and the bearing rib group of the second rib group. Good.

  According to a preferred aspect of the present invention, the first bearing portion and the second bearing portion are formed on the front surface side of the brake bracket, and the first rib group and the second rib group are on the back surface side of the brake bracket. It is good to be formed.

  According to such a configuration, since each rib group is formed on the back surface side of the brake bracket, it is possible to easily prevent interference between the vehicle parts arranged on the front surface side of the brake bracket and each rib group. In other words, the degree of freedom in designing the surface side of the brake bracket can be improved.

  According to a preferred aspect of the present invention, the first fixing portion is closer to the second bearing portion than the first bearing portion, and the second fixing portion is first than the second bearing portion. It is better to be closer to the bearing part.

  According to such a configuration, it is possible to increase the area where the first rib group and the second rib group are formed, as compared with the case where the positional relationship is opposite to these. Thereby, it is possible to secure a necessary and sufficient size for reinforcement by the ribs in an area that should be reinforced from the viewpoint of the direction of the force applied when stepping on.

  A brake bracket according to another embodiment of the present invention includes a first bearing portion and a second bearing for pivotally supporting the first end portion and the second end portion of the shaft portion of the brake pedal, respectively. A brake bracket having a portion, wherein a force is applied to the first bearing portion in a direction toward the pedal portion via the shaft portion when the pedal portion of the brake pedal is depressed, and the second bearing portion includes a pedal portion; Is provided with a first fixing portion and a second fixing portion for fixing the brake bracket to the vehicle body at two points, and the first fixing portion is a first bearing. The second fixing portion is disposed on the pedal portion side as viewed from the first bearing portion and the second bearing portion, and is disposed on the side opposite to the pedal portion as viewed from the first and second bearing portions. The bearing part and the first fixing part The to department area is formed first reinforcing structure, the region which connects the second bearing portion and a second fixing portion in which the second reinforcement structure is formed.

  According to the present invention, the strength of the region between the first bearing portion and the first fixed portion is increased by the first reinforcement structure, and the second bearing portion and the second strength are increased by the second reinforcement structure. The strength of the region that connects the fixed portion is increased. Thereby, at the time of stepping on, the first bearing portion and the second bearing portion are pulled from the back side of the direction of the force acting on them (that is, from the restraining point of the first fixing portion and the second fixing portion). As such, the strength against the force can be imparted to the brake bracket. In this manner, by appropriately reinforcing the region that is desired to be reinforced from the viewpoint of the direction of the force applied when stepped on, it is possible to secure the strength while reducing the material for the brake bracket as much as possible.

  FIG. 8 is a diagram schematically showing the principle of the reinforcing part of the brake bracket, and is a plan view of the brake bracket as seen from above, as in FIG. As described above, the brake bracket 2 is fixed to the vehicle body 3 at two points by the fixing portions 24a and 24b, and the arm portion 10 is disposed so as to bend in an oblique left direction toward the rear of the vehicle. That is, the arm part 10 is inclined to the left side of the center line YY of the bearing part 22a and the bearing part 22b (line in the vehicle front-rear direction passing through the connection point between the arm part 10 and the shaft part 14). In this case, when the driver steps on the pedal portion 12, the brake pedal 1 swings with the shaft portion 14 as a fulcrum. At this time, the bearing portions 22a and 22b are opposite to each other as indicated by arrows 81a and 81b. Will receive the rotational force. That is, when the pedal portion 12 is stepped on, the bearing portion 22a is applied with a force in the direction of the arrow 81a toward the pedal portion 12 side (second side) via the shaft portion 14, and the bearing portion 22b Thus, a force is applied in the direction of the arrow 81b toward the side opposite to the pedal portion 12 side (the first side opposite to the second side). For such a force, it is effective to increase the rigidity of the portions of the bearing portions 22a and 22b on the back side of the direction of the force.

  That is, by increasing the rigidity of the region 90a that connects the bearing portion 22a and the fixing portion 24a, the bearing portion from the restraint point (that is, the fixing portion 24a) on the reverse side of the direction of the force of the arrow 81a that the bearing portion 22a receives when stepped on. It is preferable to give strength against the force as if pulling 22a. Similarly, by increasing the rigidity of the region 90b that connects the bearing portion 22b and the fixed portion 24b, the bearing from the restraint point (that is, the fixed portion 24b) on the reverse side of the direction of the force of the arrow 81b received by the bearing portion 22b when stepped on. It is preferable to give strength against the force as if the portion 22b is pulled. In view of such a viewpoint, in the present embodiment, the first rib group 50 is formed in the former region 90a, and the second rib group 60 is formed in the latter region 90b.

  Therefore, according to the brake bracket 2 of this embodiment, it is possible to accurately reinforce the regions 90a and 90b that are desired to be reinforced from the viewpoint of the direction of the force applied when stepped on. In addition, for example, compared to the case where a grid-like rib is formed on the entire front or back surface of the brake bracket 2 for reinforcement, the area and number of ribs can be reduced, so that the strength is effectively reduced with as little resin material as possible. Can be given. That is, it is possible to achieve both weight reduction and strength securing of the brake bracket 2.

  In particular, ribs are not formed in the region connecting the bearing portion 22a and the fixing portion 24b, which are regions that need not be reinforced from the viewpoint of the direction of the force applied when stepping on, except for the bearing rib group 51. The amount of resin can be reduced. From the viewpoint of the principle of the reinforcing portion shown in FIG. 8, the two vertical ribs 72 and 73 may be omitted. This is because they are in a region connecting the bearing portion 22b and the fixing portion 24a, which are regions that do not need to be reinforced from the viewpoint of the direction of the force applied when stepping on. That is, in the present embodiment, in the region connecting the bearing portion 22a and the fixing portion 24b, it is not necessary to form a rib that connects the bearing rib group 51 at a site that defines the fixing portion 24b, or the bearing portion 22b and the fixing portion. In the region connecting with 24a, it is not necessary to form ribs (vertical ribs 72, 73) that connect the bearing rib group 61 at a site that defines the fixing portion 24a.

  The rib groups 50 and 60 that reinforce the regions 90a and 90b include bearing rib groups 51 and 61 and connecting rib groups 52 and 62, respectively. Thereby, the lower part of bearing part 22a, 22b which receives the force from the shaft part 14 at the time of depression can be reinforced with the bearing rib group 51,61. At the same time, the connection rib groups 52 and 62 can reinforce between the bearing rib groups 51 and 61 and the restraint points (fixing portions 24a and 24b).

  The embodiments of the present invention have been described above with reference to specific examples. The above specific examples are illustrations for explaining the present invention, and are not intended to limit the present invention only to the embodiments. In other words, those specific examples that have been appropriately modified by those skilled in the art are also included in the scope of the present invention as long as they have the characteristics of the present invention. For example, each element included in each of the specific examples described above and their arrangement, material, shape, size, number, and the like are not limited to those illustrated, and can be changed as appropriate.

  For example, the first and second reinforcing structures that reinforce the regions 90a and 90b are not limited to the first and second rib groups 50 and 60 including a plurality of ribs, and configurations other than ribs may be adopted. Is possible. Further, a part of the top wall 40 of the brake bracket 2 (for example, the inclined portion 42) may be omitted, or the positions of the fixing portions 24a and 24b may be changed.

  Further, a metal can be used as the material of the brake bracket 2. Even in the case of using a metal, the strength of the brake bracket 2 can be ensured while reducing the metal material used for the brake bracket 2 (that is, reducing the weight) as in the case of the resin described above. .

  In the above-described specific example, the case where the arm portion 10 of the brake pedal 1 is on the left side with respect to the center line YY of the brake bracket 2 has been described. The same applies to the case of being on the right side of Y. In the latter case, when the pedal portion 12 is depressed, a force is applied to the right bearing portion 22b shown in FIG. 8 in the direction toward the pedal portion 12 via the shaft portion 14 (the direction opposite to the arrow 81b), and A force is applied to the left bearing portion 22a shown in FIG. 8 in a direction (opposite to the arrow 81a) toward the opposite side to the pedal portion 12 via the shaft portion 14. Accordingly, the above-described reinforcing structure (region 90c connecting the right bearing portion 22b and the fixing portion 24a shown in FIG. 8 and region 90d connecting the left bearing portion 22a and the fixing portion 24a shown in FIG. The first and second rib groups may be formed. In this case, in light of the definitions of the first and second bearing portions, the right bearing portion 22b shown in FIG. 8 corresponds to the “first bearing portion”, and the left bearing portion shown in FIG. 22a corresponds to a “second bearing portion”.
