[0008] Patent Document 1: Japanese Patent No. 6325094 Summary of the invention

[0009] In the accelerator device described in Patent Document 1, a through hole portion is formed on the arm through which a connecting member can be inserted. Here, in order to ensure assembly performance when the shapes of the arm and the pedal deviate, a predetermined gap is formed between the through hole portion and the connecting member. Due to this gap, the assembly position of the arm relative to the pedal may deviate. As a result, the reaction force applied to the arm from the reaction force imparting device may deviate.

[0010] An object of the present disclosure is to provide an accelerator device capable of suppressing deviation in assembly positions while ensuring assemblability of components.

[0011] The accelerator device disclosed in the present invention comprises a pedal, an arm, a connecting member and a positioning portion. The pedal is depressed by a driver. The arm is provided in a manner connected to the pedal and is provided with a reaction force from a reaction force imparting device, which can impart a reaction force to the depression force of the driver.

[0012] The connecting member can fix the arm to the pedal. The positioning portion can limit the relative movement of the arm and the pedal. The arm has a connecting portion connected to the pedal and a through hole portion provided in the connecting portion in a manner that the connecting member can be inserted through.

[0013] The positioning portion has two mutually parallel positioning plane portions that can be engaged with other components. Therefore, by engaging the two positioning plane portions with other components, the relative movement of the arm and the pedal in a direction parallel to the positioning plane portions can be allowed, and the relative movement of the arm and the pedal in a direction perpendicular to the positioning plane portions can be restricted. Thus, the assemblability can be ensured by allowing the relative movement of the arm and the pedal in a direction parallel to the positioning plane portions, and the deviation of the assembly position can be suppressed by restricting the relative movement of the arm and the pedal in a direction perpendicular to the positioning plane portions. Therefore, it is possible to take into account both ensuring the assemblability of the components and reducing the deviation of the assembly position. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Hereinafter, accelerator devices and reaction force imparting devices to which the accelerator devices are applied according to a plurality of embodiments will be described based on the drawings. In addition, substantially the same components in the plurality of embodiments are given the same reference numerals, and description thereof will be omitted.

[0032] (First embodiment)

[0033] exist Figure 1 , Figure 2 Detailed Description of the Invention An accelerator device according to a first embodiment and a reaction force applying device to which the accelerator device is applied are shown.

[0034] The accelerator device 60 is mounted on the vehicle 1, detects the accelerator opening corresponding to the rotation angle of the pedal 70 depressed by the driver, and is used to control the driving state of the vehicle 1. The accelerator device 60 adopts a wire control acceleration method and has no mechanical connection with the throttle device of the vehicle 1. The accelerator device 60 transmits information related to the accelerator opening corresponding to the rotation angle of the pedal 70 to an electronic control unit (hereinafter referred to as "ECU") not shown. The ECU controls the throttle device based on the accelerator opening transmitted from the accelerator device 60. In this way, the driving state of the vehicle 1 is controlled.

[0035] The reaction force applying device 10 is mounted on the vehicle 1 together with the accelerator device 60, and can apply a reaction force F2 to the driver's depression force F1 to the pedal 70 of the accelerator device 60. The reaction force applying device 10 can provide driving notifications such as danger notifications and fuel efficiency improvement notifications to the driver by applying a reaction force to the pedal 70 of the accelerator device 60. In addition, the reaction force applying device 10 can limit the rotation of the pedal 70, so that the pedal 70 can be used as a footrest.

[0036] exist Figure 1 In the figure, the x-axis indicates the traveling direction of the vehicle 1, the y-axis indicates the vehicle width direction, and the z-axis indicates the vertical upward direction. In the following, unless otherwise specified, the shape or structure of the accelerator device 60 and the reaction force imparting device 10 in the state of being installed in the vehicle 1 is described. For example, "above" or "upper side" means the upper side or upper side of the accelerator device 60 or the reaction force imparting device 10 in the state of being installed in the vehicle 1. In addition, in the present embodiment, the floor panel 2 has a wall surface 7 parallel to the yz plane.

[0037] like Figure 1 to Figure 4 As shown, the accelerator device 60 includes a pedal 70, an arm 80, a connecting member 62, and a positioning portion 90. The pedal 70 is depressed by the driver. The arm 80 is provided in a manner connected to the pedal 70, and is provided with a reaction force from a reaction force applying device 10, which can apply a reaction force to the depression force of the driver.

[0038] The connecting member 62 can fix the arm 80 to the pedal 70. The positioning portion 90 can restrict the relative movement between the arm 80 and the pedal 70. The arm 80 has a connecting portion 82 connected to the pedal 70 and a through hole 84 provided in the connecting portion 82 so that the connecting member 62 can be inserted therethrough.

[0039] The positioning portion 90 has two positioning plane portions 91 that are parallel to each other and can engage with other components.

[0040] More specifically, the accelerator device 60 includes a pedal housing 61. The pedal housing 61 is fixed to the wall surface 7 of the floor panel 2 of the vehicle 1 by, for example, mounting bolts (not shown), thereby being mounted to the floor panel 2.

[0041] The pedal 70 is supported by the pedal housing 61 so as to be rotatable so as to rotate around the rotation axis Ax1. The pedal 70 is provided with a pad 71 stepped on by the driver. An accelerator opening sensor (not shown) is provided on the rotation axis Ax1 in the pedal housing 61. The accelerator opening sensor detects the accelerator opening corresponding to the rotation angle of the pedal 70 rotated by the driver's stepping operation, and transmits it to the ECU. In addition, the rotation axis Ax1 is set to be orthogonal to the z-axis and the x-axis and parallel to the y-axis.

[0042] A pedal force member (not shown) is provided in the pedal housing 61. The pedal 70 is forced in the accelerator closing direction by the pedal force member. The pedal housing 61 has a stopper for limiting the rotation of the pedal 70 in the accelerator closing direction and a stopper for limiting the rotation in the accelerator opening direction. The pedal 70 can rotate within the range of contact with the two stoppers. Figure 1 The diagram shows a state where the pedal 70 is in contact with a stopper in the accelerator closing direction, that is, a state where the accelerator is fully closed.

[0043] The pedal 70 includes a backing plate 71, a pedal base 72, and a pedal connection portion 73. The pedal connection portion 73 is formed of, for example, metal, and connects the backing plate 71 and the pedal base 72 in a manner that one end is connected to the backing plate 71 and the other end is connected to the pedal base 72. The pedal base 72 is rotatably supported by the pedal housing 61 in a manner that it rotates around the rotation axis Ax1. Thus, the pedal 70 can rotate around the rotation axis Ax1.

[0044] The arm 80 is formed in a long plate shape, and a connection portion 82 as one end portion is connected to the pedal base 72 and attached to the pedal 70. Thus, the arm 80 can rotate around the rotation axis Ax1 together with the pedal 70.

[0045] like Figure 1 , Figure 2 As shown, the reaction force applying device 10 includes an actuator 20 and a rod 40. The actuator 20 generates a driving force by energizing. The rod 40 rotates by the driving force from the actuator 20, and can apply a reaction force to the pedal 70 with respect to the driver's depression force.

[0046] More specifically, the reaction force applying device 10 includes an actuator housing 11 . The actuator housing 11 is fixed to a pedestal 9 provided on a wall surface 7 of the floor panel 2 of the vehicle 1 by, for example, mounting bolts (not shown), and is mounted to the floor panel 2 via the pedestal 9 .

[0047] The actuator 20 is, for example, an electric motor, and is housed in the actuator housing 11. The actuator 20 can output torque as a driving force by energizing. The ECU controls the energization of the actuator 20 and can control the operation of the actuator 20. A speed reducer composed of a plurality of gears (not shown) is provided in the actuator housing 11. The speed reducer can reduce the torque of the actuator 20 and output it from the shaft member 36. The shaft member 36 is provided on the rotation axis Ax2 and is supported by the actuator housing 11 so as to be rotatable around the rotation axis Ax2.

[0048] The rod 40 includes a rod body 41, a rod one end 42, a rod other end 43, etc. The rod body 41 is formed into a rod shape by metal, etc., for example. The rod one end 42 is connected to one end of the rod body 41 and is formed integrally with the rod body 41. The rod other end 43 is connected to the other end of the rod body 41 and is formed integrally with the rod body 41. The rod other end 43 is formed to be substantially perpendicular to the rod body 41. The rod other end 43 is provided in a manner parallel to the y-axis.

[0049] The rod 40 is provided so that one end portion 42 of the rod is connected to the shaft member 36. Thus, the rod 40 is rotatably supported by the actuator housing 11 so as to rotate around the rotation axis Ax2 together with the shaft member 36. The rod 40 rotates around the rotation axis Ax2 by the driving force from the actuator 20 output from the shaft member 36.

[0050] like Figure 1 As shown, the reaction force applying device 10 is provided so that the outer peripheral wall of the other end portion 43 of the rod can abut against the surface of the arm 80 of the accelerator device 60 on the side opposite to the floor panel 2 and can be separated from the surface of the arm 80 on the side opposite to the floor panel 2. Thus, the reaction force applying device 10 can apply the reaction force F2 to the driver's depression force F1 to the pedal 70 via the arm 80 from the rod 40 rotated by the driving force from the actuator 20.

[0051] Next, the structure of the accelerator device 60 will be described in detail.

[0052] like Figure 4 As shown, the pedal 70 has a pedal hole 74 and a nut 75. The pedal base 72 is formed of, for example, resin. Two pedal holes 74 are formed in a hole-like recessed manner from the outer wall of the pedal base 72. The nut 75 is formed of, for example, metal in a cylindrical shape, and a thread groove is formed on the inner peripheral wall. The nut 75 is provided in the two pedal holes 74, for example, by hot pressing. Here, the nut 75 is a component constituting a part of the pedal 70.

[0053] The arm 80 includes an arm body 81, a connecting portion 82, a reaction force receiving abutment surface 83, and a through hole portion 84. The arm body 81 is formed by, for example, bending a long plate-shaped member made of metal at a predetermined position (see Figure 2 , Figure 3 The connecting portion 82 is formed at one end of the arm body 81. The reaction force receiving contact surface 83 is formed in a planar shape on the side surface in the plate surface direction of the other end of the arm body 81 (see Figure 1 to Figure 3 , Figure 5 ).

[0054] Two through-holes 84 are provided in the connecting portion 82. The through-holes 84 are formed so as to penetrate the connecting portion 82 in the plate thickness direction. The through-hole 841, which is one of the two through-holes 84, is formed in a long hole shape (see Figure 5 ). The other through hole portion 842 of the two through hole portions 84 is formed in a cylindrical shape.

[0055] The connecting member 62 is a so-called screw made of metal, for example. The connecting member 62 has a head 621, a shaft 622 (see Figure 4 The head 621 is formed in a substantially disk shape. The shaft 622 is formed so as to extend in the axial direction from the center of the head 621. A thread that can be threadedly connected to the thread groove of the nut 75 is formed on the outer peripheral wall of the shaft 622.

[0056] This embodiment includes two connection members 62. One of the two connection members 62 is provided so as to pass through the through hole 841 and be screwed to one of the two nuts 75. The other of the two connection members 62 is provided so as to pass through the through hole 842 and be screwed to the other of the two nuts 75.

[0057] The connecting member 62 can fix the arm 80 to the pedal 70 by sandwiching the connecting portion 82 between the head portion 621 and the nut 75 . The connecting portion 82 is connected to the nut 75 which is a part of the pedal 70 .

[0058] The positioning plane portion 91 is provided in the through hole portion 841 .

[0059] The positioning plane portion 91 is formed with two inner walls of the through hole portion 841 (see Figure 5 , Figure 6 ). The positioning plane portion 911, which is one of the two positioning plane portions 91, is formed on one of the two opposing planar inner walls of the through hole portion 841. The positioning plane portion 912, which is the other of the two positioning plane portions 91, is formed on the other of the two opposing planar inner walls of the through hole portion 841. The positioning plane portion 911 and the positioning plane portion 912 are parallel to each other.

[0060] The positioning plane portions 911 and 912 are parallel to a straight line L1 connecting the centers of two connecting members 62 among the plurality of connecting members 62 (see Figure 6 ).

[0061] As Figure 6 shown, if the outer diameter of the shaft portion 622 of the connecting member 62 is R1, the inner diameter of the through-hole portion 842 is R2, the width in the short side direction of the through-hole portion 841 is W1, and the width in the long side direction of the through-hole portion 841 is W2, then the connecting member 62 and the through-hole portion 842 are formed to satisfy the relationship of 1.001 < R2 / R1 < 1.1, for example. In addition, the connecting member 62 and the through-hole portion 841 are formed to satisfy the relationships of 1.001 < W1 / R1 < 1.1 and 1.01 < W2 / R1, for example. Here, R2 = W1. In addition, W1 is equal to the distance between the positioning plane portion 911 and the positioning plane portion 912.

[0062] In addition, W2 is set to a size such that the shaft portion 622 can relatively move in the long side direction of the through-hole portion 841 inside the through-hole portion 841.

[0063] The positioning plane portion 911 and the positioning plane portion 912 are parallel planes that can engage with the connecting member 62 as other components.

[0064] In the present embodiment, when assembling the arm 80 to the pedal 70, with the shaft portions 622 of the two connecting members 62 respectively inserted through the through-hole portion 841 and the through-hole portion 842 and a part of the shaft portion 622 being threadedly connected to the nut 75, the relative movement of the arm 80 and the pedal 70 in a direction perpendicular to the positioning plane portion 91 can be restricted, and the relative movement of the arm 80 and the pedal 70 in a direction parallel to the positioning plane portion 91 can be permitted, and the assembling position of the arm 80 relative to the pedal 70 can be adjusted.

[0065] The reaction force receiving abutting surface 83 is provided so as to be able to abut against the rod 40 of the reaction force applying device 10 and receive the reaction force with respect to the driver's depressing force from the rod 40. More specifically, the reaction force receiving abutting surface 83 can abut against the outer peripheral wall of the other end portion 43 of the rod 40.

[0066] The positioning plane portion 911 and the positioning plane portion 912 are parallel to the reaction force receiving abutting surface 83 (see Figure 5 , Figure 6 ).

[0067] Therefore, when assembling the arm 80 to the pedal 70, even if the assembling position of the arm 80 relative to the pedal 70 is displaced in a direction parallel to the positioning plane portion 91, the deviation of the relative position between the other end portion 43 of the rod and the reaction force receiving abutting surface 83 can be suppressed.

[0068] As described above, in this embodiment, the connecting member 62 can fix the arm 80 to the pedal 70. The positioning portion 90 can restrict the relative movement of the arm 80 and the pedal 70. The arm 80 has a connecting portion 82 connected to the pedal 70, and a through hole portion 84 provided in the connecting portion 82 to allow the connecting member 62 to be inserted therethrough.

[0069] The positioning portion 90 has two mutually parallel positioning plane portions 91 that can be engaged with the connecting member 62 as other components. Therefore, by engaging the two positioning plane portions 91 with the connecting member 62, it is possible to allow the arm 80 and the pedal 70 to move relative to each other in a direction parallel to the positioning plane portions 91, and to limit the relative movement of the arm 80 and the pedal 70 in a direction perpendicular to the positioning plane portions 91. Thus, it is possible to ensure assemblability by allowing the arm 80 and the pedal 70 to move relative to each other in a direction parallel to the positioning plane portions 91, and to suppress the deviation of the assembly position by limiting the relative movement of the arm 80 and the pedal 70 in a direction perpendicular to the positioning plane portions 91. Therefore, it is possible to take into account both ensuring the assemblability of the components and reducing the deviation of the assembly position. Thus, it is possible to suppress the deviation of the reaction force imparted to the arm 80 by the reaction force imparting device 10.

[0070] In addition, in the present embodiment, the positioning plane portions 911 and 912 are parallel to the straight line L1 connecting the centers of two connecting members 62 among the plurality of connecting members 62 .

[0071] Therefore, the connecting member 62 can be used as another member to be engaged with the positioning flat surface portion 91. Therefore, the number of components can be reduced compared with the case where another member to be engaged with the positioning flat surface portion 91 is separately provided.

[0072] In the present embodiment, the reaction force receiving abutment surface 83 is provided to be able to abut against the rod 40 of the reaction force applying device 10 and receive a reaction force to the driver's depression force from the rod 40. The positioning plane portion 91 is parallel to the reaction force receiving abutment surface 83.

[0073] Therefore, when the arm 80 is assembled to the pedal 70, even if the assembly position of the arm 80 relative to the pedal 70 is displaced in a direction parallel to the positioning plane portion 91, it is possible to suppress the relative position deviation between the other end portion 43 of the rod and the reaction force receiving abutment surface 83. Thus, it is possible to suppress the reaction force applied to the arm 80 from the reaction force applying device 10 from deviating.

[0074] Furthermore, in the present embodiment, the positioning plane portion 91 is provided in the through hole portion 841 .

[0075] Therefore, the connecting member 62 can be used as another member to be engaged with the positioning flat surface portion 91 .

[0076] (Second embodiment)

[0077] exist Figure 7 to Figure 9 2 shows an accelerator device according to a second embodiment and a part thereof. The structures of a pedal 70 and an arm 80 of the second embodiment are different from those of the first embodiment.

[0078] In the present embodiment, the positioning portion 90 includes a positioning recess 92 provided in the pedal 70 and a positioning protrusion 93 provided in the connection portion 82 and capable of entering the positioning recess 92. The positioning flat surface portion 91 is provided in the positioning recess 92.

[0079] More specifically, two positioning recesses 92 are provided in the pedal base 72. The positioning recess 921, which is one of the two positioning recesses 92, is formed in a hole-like manner recessed from the outer wall of the pedal base 72 on one side in a direction perpendicular to the straight line L2 passing through the centers of the two pedal holes 74 (see FIG. Figure 8 The other positioning recess 922 of the two positioning recesses 92 is formed on the other side in the direction perpendicular to the straight line L2 so as to be recessed from the outer wall of the pedal base 72 in a hole shape.

[0080] The positioning recess 921 is formed in a long hole shape. The positioning recess 922 is formed in a cylindrical shape. The positioning plane portion 91 is formed with two inner walls of the positioning recess 921 (see Figure 8 ). The positioning plane portion 911, which is one of the two positioning plane portions 91, is formed on one of the two opposing planar inner walls of the positioning recess 921. The positioning plane portion 912, which is the other of the two positioning plane portions 91, is formed on the other of the two opposing planar inner walls of the positioning recess 921. The positioning plane portion 911 and the positioning plane portion 912 are parallel to each other.

[0081] Two positioning protrusions 93 are provided on the connecting portion 82 (see Fig. 9 ). The positioning protrusion 931 as one of the two positioning protrusions 93 is formed in a cylindrical shape protruding from the end surface of the connecting portion 82 on one side in a direction perpendicular to the straight line L3 passing through the centers of the through-hole portion 841 and the through-hole portion 842. The positioning protrusion 932 as the other of the two positioning protrusions 93 is formed in a cylindrical shape protruding from the end surface of the connecting portion 82 on the other side in a direction perpendicular to the straight line L3.

[0082] In addition, at positions corresponding to the positioning protrusions 931 and 932 on the end surface of the connecting portion 82 on the opposite side from the positioning protrusions 93, recessed portions 933 and 934 are formed that are recessed corresponding to the shapes of the positioning protrusions 931 and 932 (see Figure 8 ).

[0083] The positioning protrusions 931 and 932 are formed so as to be respectively able to enter the positioning recesses 921 and 922. Here, the positioning flat surfaces 911 and 912 can be engaged with the outer peripheral wall of the positioning protrusion 931 formed on the arm 80 as another member.

[0084] In the present embodiment, the through hole portion 841 is formed in a cylindrical shape. The positioning flat surface portions 911 and 912 are not parallel to the reaction force receiving abutment surface 83 .

[0085] In this embodiment, when the arm 80 is assembled to the pedal 70, with the positioning protrusions 931 and 932 respectively entering the positioning recesses 921 and 922, the relative movement of the arm 80 and the pedal 70 in a direction perpendicular to the positioning plane portion 91 can be restricted, and the relative movement of the arm 80 and the pedal 70 in a direction parallel to the positioning plane portion 91 can be allowed, thereby adjusting the assembly position of the arm 80 relative to the pedal 70.

[0086] As described above, in this embodiment, the positioning portion 90 includes the positioning recess 92 provided in the pedal 70 and the positioning projection 93 provided in the connection portion 82 and capable of entering the positioning recess 92. The positioning flat surface portion 91 is provided in the positioning recess 92.

[0087] Therefore, the relative movement between the arm 80 and the pedal 70 can be restricted by the positioning portion 90 , and the arm 80 can be fixed to the pedal 70 by the connecting member 62 .

[0088] (Third embodiment)

[0089] exist Figure 10 to Figure 12 2 shows an accelerator device according to a third embodiment and a part thereof. The configurations of a pedal 70 and an arm 80 of the third embodiment are different from those of the first embodiment.

[0090] In this embodiment, the positioning portion 90 includes a positioning recess 94 provided in the pedal 70, and a positioning protrusion 95 provided in the connecting portion 82 and capable of entering the positioning recess 94. Positioning plane portions 941 and 942 are provided in the positioning recess 94. Positioning plane portions 951 and 952 are provided in the positioning protrusion 95.

[0091] More specifically, one positioning recess 94 is provided in the pedal base 72. The positioning recess 94 is formed so as to be recessed in a hole shape from the outer wall of the pedal base 72. The positioning recess 94 is formed in a long hole shape.

[0092] The positioning plane portion 941 is formed on one of the two opposing planar inner walls of the positioning recess 94. The positioning plane portion 942 is formed on the other of the two opposing planar inner walls of the positioning recess 94. The positioning plane portion 941 and the positioning plane portion 942 are parallel to each other.

[0093] Two pedal holes 74 are formed on the bottom surface of the positioning recess 94. Nuts 75 are provided in the pedal holes 74.

[0094] One positioning protrusion 95 is provided on the connecting portion 82 (see Fig.12 The positioning protrusion 95 is formed so as to protrude from the end surface of the connection portion 82. The positioning protrusion 95 is formed into an oblong shape so that the shape of the cross section perpendicular to the protruding direction corresponds to the shape of the cross section perpendicular to the recessed direction of the positioning recess 94.

[0095] The positioning flat surface portion 951 is formed on one of the two planar outer walls of the positioning protrusion 95 that are parallel to each other. The positioning flat surface portion 952 is formed on the other of the two planar outer walls of the positioning protrusion 95 that are parallel to each other.

[0096] In addition, a recessed portion 953 that is recessed in accordance with the shape of the positioning protrusion 95 is formed at a position corresponding to the positioning protrusion 95 on the end surface of the connection portion 82 on the opposite side to the positioning protrusion 95 .
