Detailed Implementation

[0038] Hereinafter, examples of embodiments of the present invention will be described with reference to the accompanying drawings.

[0039] Figure 1 This is a front view of the vehicle door opening and closing operation device according to this embodiment. Figure 2 This is a rear view of the vehicle door opening and closing operation device according to this embodiment. Figure 3 yes Figure 2 Sectional view III-III. Figure 4 This is an exploded perspective view of the door opening and closing mechanism for a vehicle.

[0040] like Figures 1 to 4 As shown, the vehicle door opening and closing operation device 1 of this embodiment is provided on the door 2 of a vehicle such as an automobile. An operation opening 5 is formed on the outer panel 3 of the door 2 on which the vehicle door opening and closing operation device 1 is provided, and the space inside the door 2 communicates with the outside through the operation opening 5.

[0041] The vehicle door opening and closing operating device 1 includes a cover swing mechanism 20 and a door opening and closing mechanism 100. These cover swing mechanism 20 and door opening and closing mechanism 100 are housed in a housing 10. The cover swing mechanism 20 is embedded in the upper part of the housing 10, and the door opening and closing mechanism 100 is embedded in the lower part of the housing 10. In this vehicle door opening and closing operating device 1, the cover swing mechanism 20 and the door opening and closing mechanism 100 are controlled by a control unit (not shown).

[0042] The housing 10 is formed as a box shape having a front surface portion 11, a rear surface portion 12, and side portions 13 and 14. Mounting portions 16 with through holes 16a are formed in the upper and lower parts of the housing 10. Two mounting portions 16 are provided at the upper end of the housing 10, and one mounting portion 16 is provided at the lower end of the housing 10. The vehicle door opening and closing operating device 1 secures the mounting portion 16 to the outer panel 3 by screwing a bolt (not shown) inserted into the through hole 16a of the mounting portion 16 into a bracket (not shown) of the outer panel 3.

[0043] The housing 10 has an upper part with a cover swing mechanism 20 that is open at the rear, and a lower part with a door opening and closing mechanism 100 that is open at the front. A rear cover 17 is mounted on the upper part of the rear surface 12 at the rear of the housing 10.

[0044] An opening 21 with a shape substantially the same as the operation opening 5 of the outer panel 3 is formed on the front surface portion 11 of the housing 10. This opening 21 is formed at a position that communicates with the operation opening 5 of the outer panel 3 when the vehicle door opening and closing operation device 1 is fixed to the outer panel 3.

[0045] Furthermore, in the housing 10, a mounting hole 18 is formed on one side 13 adjacent to the operating opening 5, and a cylindrical lock 19 is installed in the mounting hole 18. In the vehicle door opening and closing operation device 1, by inserting a key (not shown) into the cylindrical lock 19 through the operating opening 5 and operating it, the locking mechanism of the door 2 relative to the vehicle body (not shown) can be locked and unlocked.

[0046] Figure 5 This is the front view of the cover swing mechanism. Figure 6 This is a rear view of the cover swing mechanism.

[0047] like Figure 5 and Figure 6 As shown, the cover swing mechanism 20 has a linkage unit 30 and a swing unit 70. These linkage units 30 and swing units 70 are housed in the upper part of the housing 10.

[0048] Figure 7 This is a 3D view of a linkage unit. Figure 8 This is the front view of the linkage unit. Figure 9 This is a side view of the linkage unit.

[0049] like Figures 7 to 9 As shown, the linkage unit 30 has a cover member 31, a first linkage portion 32, and a second linkage portion 33.

[0050] The cover member 31 is formed in the shape of a plate. The cover member 31 has a shape slightly smaller than the opening 21 formed on the front surface portion 11 of the housing 10. In the cover member 31, a first connecting portion 35 and a second connecting portion 37 are formed near both ends of its rear surface. The first connecting portion 35 is formed above the rear surface of the cover member 31, and the second connecting portion 37 is formed below the first connecting portion 35 on the rear surface of the cover member 31.

[0051] The first link portion 32 has a pair of first link arms 41. One end 41a of the first link arm 41 is rotatably connected to the first connection portion 35 of the cover member 31. The first link arm 41 is bent forward near the other end 41b.

[0052] The second link section 33 has a pair of second link arms 51. The second link arms 51 are bent at approximately a right angle at their middle portions. The second link arms 51 of the second link section 33 are positioned outside the first link arm 41 of the first link section 32.

[0053] In the second linkage arm 51, one end 51a is connected to the other via a connecting rod 53 (see reference). Figure 4 A pair of connecting pieces 53a are formed on the connecting rod 53, and these connecting pieces 53a are rotatably connected to the second connecting portion 37 of the cover member 31. In addition, a through hole 54 is formed at the other end 51b of the second connecting arm 51.

[0054] The bent middle portions of the second linkage arms 51 are connected to each other via cam rods 55. Cam rods 55 have a crank portion 56 formed in the shape of a crank and a cam follower portion (engaging portion) 58 fitted with a bushing 57. The bushing 57 is made of, for example, resin material and has a shape in which multiple claw portions 57b are erected from both edges of the flat plate portion 57a. In this bushing 57, the claw portions 57b erected from both edges of the flat plate portion 57a ​​grip the cam rod 55, thereby engaging it with the cam rod 55. Thus, the cam rod 55 forms a cam follower portion 58 fitted with the bushing 57.

[0055] In the second link arm 51, a plate-shaped portion 61 is formed at the bend in the middle, through which the second link arm 51 is reinforced from the middle to the other end 51b. In one plate-shaped portion 61 of the second link arm 51, a sector-shaped gear portion 62 is formed on its outer surface. A gear 64 of a damper 63 meshes with this gear portion 62, and the damper 63 is fitted into a mounting hole 65 on one side surface 13 of the housing 10 (see reference). Figure 4 ).

[0056] like Figure 1 and Figure 4 As shown, for the first link arm 41 of the first link portion 32 constituting the link unit 30, its other end 41b is inserted from the inside of the housing 10 and rotatably supported on the upper part of the front surface portion 11 of the housing 10 near the two side portions of the support recess 67.

[0057] Furthermore, for the second link arm 51 constituting the second link portion 33 of the link unit 30, a support rod 68, which is attached to the front surface portion 11 of the housing 10, is inserted through and rotatably supported in a through hole 54 formed at the other end 51b of the second link arm 51. The coil spring 69 of the second link portion 33, which is mounted on the support rod 68, is oriented in one direction relative to the rotation direction. Figure 3 Apply force in the R1 direction.

[0058] In the linkage unit 30, the first link portion 32 and the second link portion 33 of the support cover member 31 form a parallel link. That is, the first link arm 41 of the first link portion 32 and the second link arm 51 of the second link portion 33 rotate around their respective other ends 41b and 51b as fulcrums, thereby maintaining the cover member 31 in approximately the same posture movement.

[0059] Figure 10 This is a rear view of the swing mechanism of the door opening and closing device for vehicles. Figure 11 This is a cross-sectional view of the swing mechanism of the door opening and closing device for vehicles.

[0060] like Figure 4 , Figure 10 as well as Figure 11 As shown, the swing unit 70 has a box-shaped housing 73 with an open rear surface, inside which a motor 71 and a cam member 72 are housed. A cover member 74 is threadedly fixed to and mounted on the open rear surface of the housing 73 by screws 75. A sealing member 76 is provided between the housing 73 and the cover member 74, thereby sealing the space between them.

[0061] In the housing 73, two mounting portions 77 with insertion holes 77a are formed on its upper part. When the swing unit 70 is housed in the housing 10, the mounting portions 77 of the housing 73 overlap with the mounting portions 16 of the housing 10, and their respective insertion holes 16a and 77a are connected. In this state, the mounting portions 16 and 77 are jointly fastened to the bracket of the outer panel 3 by screwing the bolts (not shown) inserted into the mutually connected insertion holes 16a and 77a into the bracket (not shown).

[0062] The motor 71, housed inside the housing 73, is powered and driven via a power supply wire (not shown) connected to the electrode terminal 81. The motor 71 is arranged within the housing 73 with its drive shaft 71a facing laterally. A worm gear 82 is provided on the drive shaft 71a of the motor 71.

[0063] Inside the housing 73, between the motor 71 and the cam member 72, a reduction gear 83 is supported in a manner that allows it to rotate around an axis in the front-to-back direction. The reduction gear 83 has a major diameter gear 84 and a minor diameter gear 85, and the worm gear 82 of the motor 71 meshes with the major diameter gear 84 of the reduction gear 83.

[0064] The cam member 72 is formed in the shape of a circular plate and is supported inside the housing 73 so that it can rotate about a rotation axis 72a in the front-rear direction. The cam member 72 has an annular gear portion 86 on its front surface side, and a small diameter gear 85 of a reduction gear 83 meshes with the annular gear portion 86.

[0065] In the cam member 72, a forward-protruding switch operation protrusion 87 is formed on the inner side of the annular gear portion 86 on its front surface side. Furthermore, a rearward-protruding cam protrusion (protrusion portion) 88 is formed on the rear surface side of the cam member 72. These switch operation protrusions 87 and cam protrusions 88 are disposed on the inner side of the outer shape of the cam member 72, and are each formed in an arc shape centered on the rotation axis 72a. A circular window portion 74a is formed in the cover member 74 mounted on the housing 73, and the rear surface side of the cam member 72 with the cam protrusion 88 is fitted into this window portion 74a. This window portion 74a and the cam member 72 are sealed by an annular sealing member 89.

[0066] The cam protrusion 88 of the cam member 72 is positioned below the cam follower 58, which is fitted with a bushing 57, in the cam rod 55 of the second link portion 33 constituting the link unit 30. When the cam member 72 rotates, the cam protrusion 88 presses the cam follower 58 upward. In other words, the cam follower 58 is pushed by the cam protrusion 88 of the cam member 72.

[0067] Two stop switches 91 and 92 are provided inside the housing 73. These stop switches 91 and 92 are supported by a support member 90 at different positions around the rotation axis 72a on the front side of the cam member 72. These stop switches 91 and 92 are turned on (ON) or off (OFF) by contacting and separating from the switch-operating protrusion 87 of the cam member 72.

[0068] Furthermore, the swing unit 70 has two sensing switches 95 and 96 on its rear surface side. These sensing switches 95 and 96 are mounted on the cover member 74 installed in the housing 73. One sensing switch 95 is located at the lower part of the swing unit 70, and the other sensing switch 96 is located at the upper part of the swing unit 70. These sensing switches 95 and 96 are turned on (ON) and off (OFF) by contacting and separating from the cam rod 55 constituting the second link portion 33 of the link unit 30.

[0069] In the cover swing mechanism 20 composed of the aforementioned linkage unit 30 and swing unit 70, the cam follower 58 of the cam rod 55 is positioned overlapping the cam member 72 in the front view of the vehicle door opening and closing operation device 1. Furthermore, the swing unit 70 is disposed between a pair of first linkage arms 41 and a pair of second linkage arms 51 of the first linkage portion 32 and the second linkage portion 33 constituting the linkage unit 30.

[0070] like Figure 1 , Figure 3 as well as Figure 4 As shown, the door opening and closing mechanism 100 has an operating lever 101. The operating lever 101 has a front panel 102, a side panel 103, and a bottom 104. The operating lever 101 is housed in the lower part of the housing 10, which is open on the front side. In the operating lever 101, the front side of its bottom 104 is supported by a support shaft 105 so that it can rotate relative to the housing 10.

[0071] In the operating lever 101, there is an inwardly protruding locking protrusion 111 near the upper edge of the front surface plate portion 102. In addition, the operating lever 101 has a rearwardly protruding protrusion 112 at the bottom 104, which protrudes toward the rear side of the rear surface portion 12 of the housing 10.

[0072] A pressing lever 113 is provided on the rear surface portion 12 of the housing 10. The pressing lever 113 is rotatably mounted to the rear surface portion 12 of the housing 10 via a shaft member 114, a washer 115, and a riveting member 116. A pressing piece 113a is formed at one end of the pressing lever 113, and the pressing piece 113a abuts against the upper part of the protrusion 112 of the operating lever 101. A recess 117 is formed on the rear surface portion 12 of the housing 10. The recess 117 is configured such that when the pressing lever 113 rotates, the other end 113b of the pressing lever 113 does not abut against the inner wall surface 117a of the recess 117, thus restricting rotation (see reference). Figure 2 ).

[0073] The pressing lever 113 is assembled to the helical spring 118 of the shaft member 114, and the elastic force is directed in one direction. Figure 2 A force is applied in the R2 direction. As a result, the protrusion 112 of the operating lever 101 is pushed down by the pressing piece 113a of the pressing lever 113. Therefore, the operating lever 101 moves in a direction towards the inward side of the housing 10, centered on the support shaft 105. Figure 3 A force is applied in the R3 direction (of the sample).

[0074] In the door opening and closing mechanism 100, the user inserts their finger into the operating opening 5 of the outer panel 3 and the opening 21 of the housing 10, hooks the locking protrusion 111, and pulls it forward, thereby operating the lever 101 in the direction of force application. Figure 3 The door 2 swings in the opposite direction (R3 direction). As a result, the door 2 is opened relative to the vehicle body (not shown). It should be noted that the door 2 can be mechanically opened by the operating force of the operating lever 101, or it can be opened by a drive unit that senses and drives the operation of the operating lever 101.

[0075] Next, the operation of the cover swing mechanism 20 will be explained.

[0076] Figures 12 to 18 This is an explanatory diagram illustrating the motion of the cover's swing mechanism.

[0077] like Figure 11 and Figure 12 As shown, in the cover swing mechanism 20, in the closed state, the cover member 31 of the linkage unit 30 is embedded in the opening 21 of the housing 10, and the operation opening 5 of the outer panel 3 of the door 2 is closed by the cover member 31. Furthermore, as... Figure 10 As shown, in the closed state, the crank portion 56 of the cam rod 55 of the second link portion 33 constituting the link unit 30 contacts the sensing switch 95, which is in the ON state.

[0078] In the closed state, the user who opens the vehicle door 2 pushes the cover member 31 of the linkage unit 30 in with their finger. When the cover member 31 is pushed in, it displaces towards the operating space 7 inside the door 2, overcoming the force applied by the coil spring 69. Consequently, the first link 32 and the second link 33 of the linkage unit 30 swing against the force applied by the coil spring 69, and the crank portion 56 of the cam rod 55 of the second link 33 separates from the sensing switch 95, putting the sensing switch 95 in the OFF state. The control unit then performs authentication, for example, based on an authentication code from the electronic key held by the user. When authentication is successful, the control unit releases the locking mechanism of the door 2 relative to the vehicle body and drives the swing unit 70.

[0079] In the oscillating unit 70, a motor 71 is driven, and the rotation of the motor 71 is slowed down by a reduction gear 83 and transmitted to the cam member 72. Thus, the cam member 72 moves in one direction ( Figure 10 The cam protrusion 88 of the cam member 72 located below rotates upwards while contacting the cam follower 58 of the cam rod 55 as the cam member 72 rotates.

[0080] like Figure 13 As shown, when the cam protrusion 88 of the cam member 72 rotates upward, the cam rod 55 is pushed upward. Thus, as... Figure 14 and Figure 15 As shown, the first link portion 32 and the second link portion 33 of the parallel link constituting the link unit 30 swing respectively, thereby maintaining the posture of the cover member 31 while moving into the operating space 7. As a result, the opening portion 21 of the housing 10 and the operating opening portion 5 of the outer panel 3 are in the open state.

[0081] When in the open state, the switching protrusion 87 of the cam member 72 contacts the stop switch 92, which is in the ON state. As a result, the drive of the motor 71 is stopped, the swing of the linkage unit 30 is stopped, and the cover member 31 remains in the open position.

[0082] In this open state, the user inserts their fingers into the operating opening 5 of the outer panel 3 and the opening 21 of the housing 10, hooks their fingers onto the locking protrusion 111 of the operating lever 101 of the door opening and closing mechanism 100, and pulls the operating lever 101 forward. As a result, the door 2 is opened relative to the vehicle body.

[0083] In this open state, when the user pushes the cover member 31 of the linkage unit 30, which is set to the open state, with their finger, as... Figures 16 to 17As shown, the cover member 31 is set to the fully open state where it is pushed inward, and the cam rod 55 of the second link portion 33 constituting the link unit 30 contacts the sensing switch 96. As a result, the sensing switch 96 is set to the ON state.

[0084] When the sensing switch 96 is set to the ON state, the motor 71 of the swing unit 70 is driven, and the cam member 72 moves in the opposite direction. Figure 16 The cam protrusion 88 of the upper cam member 72 rotates downward. As the cam protrusion 88 of the cam member 72 rotates downward, the cam rod 55 of the second link portion 33, which is stressed by the coil spring 69, descends. Consequently, the first link portion 32 and the second link portion 33, constituting the parallel link of the link unit 30, move in the direction of force application (R5 direction). Figure 3 The cam member 31 swings in the R1 direction, thereby maintaining its posture while moving towards the opening 21 of the housing 10 and the operating opening 5 of the outer panel 3. Furthermore, when the cam protrusion 88 rotates downwards, the switch-operating protrusion 87 of the cam member 72 contacts the stop switch 91, which is in the ON state. Thus, the drive of the motor 71 is stopped, and the swinging of the linkage unit 30 is stopped. Then, by the force applied by the coil spring 69, the cam member 31 of the linkage unit 30 is engaged in the opening 21 of the housing 10, and the operating opening 5 of the outer panel 3 of the door 2 is in the closed state, closed by the cam member 31 (see reference). Figure 11 and Figure 12 Furthermore, since it is in this closed state, the crank portion 56 of the cam rod 55 of the second link portion 33 constituting the link unit 30 contacts the sensing switch 95, which is in the ON state. As a result, the control unit sensing cover swing mechanism 20 is in the closed state.

[0085] As explained above, the vehicle door opening and closing operation device 1 according to this embodiment is constructed such that the cam follower 58 coincides with the cam member 72 in the main view, and the cam protrusion 88 of the cam member 72 that pushes the cam follower 58 is disposed inside the outer shape of the cam member 72, thus enabling the compactness of the cover swing mechanism 20. This results in the overall miniaturization of the vehicle door opening and closing operation device 1 and the saving of space within the vehicle door 2.

[0086] Furthermore, the linkage unit 30 has a parallel linkage structure with a first linkage portion 32 and a second linkage portion 33, and the cover member 31 moves between the closed position and the open position while maintaining its posture via the linkage unit 30. Therefore, in the open state where the operating opening 5 is open, for example, the protrusion caused by the tilted arrangement of the cover member 31 can be eliminated. Therefore, in the open state, a larger operating space 7 can be ensured inside the operating opening 5, improving the operability of the user's door opening and closing mechanism 100.

[0087] Furthermore, the first linkage 32 has a pair of first linkage arms 41, the second linkage 33 has a pair of second linkage arms 51, and the swing unit 70 is disposed between the pair of first linkage arms 41 and the pair of second linkage arms 51. Therefore, the swing mechanism 20 can be further compacted, and the vehicle door opening and closing operation device 1 can be made smaller.

[0088] Furthermore, the presence of a damper 63 that applies a load to the linkage unit 30 reduces the force applied by the helical spring 69 when the linkage unit 30 swings and the cover member 31 moves, allowing the cover member 31 to slowly return to the closed position, thus improving its marketability.

[0089] It should be noted that the present invention is not limited to the embodiments described above, and can be appropriately modified and improved. Furthermore, as long as the present invention can be realized, the material, shape, size, quantity, and arrangement of the constituent elements in the above embodiments are arbitrary and not limited.

[0090] For example, in this embodiment, the linkage unit 30 is configured as follows: it employs a parallel linkage structure having a first linkage portion 32 and a second linkage portion 33, thereby allowing the cover member 31 to move between a closed position and an open position while maintaining an attitude, but this is not a limitation. Alternatively, the linkage unit may employ a single-degree-of-freedom linkage structure without a first linkage portion 32, whereby the second linkage portion 33 is connected to the cover member 31 in a non-rotational manner, thereby allowing the cover member 31 to move between a closed position and an open position by rotating relative to the surface of the door 2.

[0091] Here, the features of the embodiments of the vehicle door opening and closing operation device of the present invention described above are briefly summarized and listed as follows [1] to [6].

[0093] The cover swing mechanism (20) has a cover member (31) that moves between a closed position blocking the operating opening (5) of the door (2) of the vehicle and an open position opening the operating opening (5); and

[0094] A door opening and closing operation unit (100) is disposed inside the door (2), and is operated by the user through the operation opening (5) to open and close the door (2).

[0095] The cover swing mechanism (20) has:

[0096] Linkage unit (30), capable of swinging, supports the cover member (31) so that it can move between the closed position and the open position; and

[0097] The swing unit (70) includes a cam member (72) that rotates via a motor (71). The swing unit (70) uses a protrusion (cam protrusion 88) provided on the cam member (72) to push the engaging part (cam follower 58) of the linkage unit (30) and cause the linkage unit (30) to swing, thereby moving the cover member (31).

[0098] At least a portion of the engaging portion (cam follower 58) coincides with the cam member (72) in the main view.

[0099] The vehicle door opening and closing operating device according to the above [1] configuration has the following structure: at least a portion of the engaging part coincides with the cam member in the main view, thus enabling the compactness of the cover swing mechanism. As a result, the overall miniaturization of the vehicle door opening and closing operating device can be achieved, and the space inside the vehicle door can be saved.

[0100] [2] According to the vehicle door opening and closing operation device described in [1] above, the protrusion (cam protrusion 88) is disposed on the inner side of the outer shape of the cam member (72).

[0101] The vehicle door opening and closing operation device according to the above [2] has the following structure: the protrusion of the cam member that pushes the engagement part is arranged inside the outer shape of the cam member, so that the cover swing mechanism part can be further compacted.

[0102] [3] According to the vehicle door opening and closing operation device described in [1] or [2] above, wherein,

[0103] The linkage unit (30) has a parallel linkage structure having a first linkage portion (32) and a second linkage portion (33).

[0104] The cover member (31) moves between the closed position and the open position in a posture-maintaining state via the link unit (30).

[0105] According to the vehicle door opening and closing operating device configured as described above [3], the cover member moves between the closed position and the open position while maintaining its posture via the linkage unit. Therefore, in the open state where the operating opening is open, for example, the protrusion caused by the tilted arrangement of the cover member can be eliminated. Therefore, in the open state, a larger operating space can be ensured inside the operating opening, improving the operability of the user's door opening and closing mechanism.

[0106] [4] According to the vehicle door opening and closing operation device described in [3] above, wherein,

[0107] The first link section (32) and the second link section (33) each have a pair of link arms (41, 51).

[0108] The swing unit (70) is disposed between a pair of the connecting arms (41, 51).

[0109] According to the vehicle door opening and closing operation device configured as described above [4], the swing unit is arranged between the linkage arms, so it is possible to further compact the swing mechanism and make the vehicle door opening and closing operation device smaller.

[0110] [5] According to the vehicle door opening and closing operation device described in [1] or [2] above, wherein,

[0111] It has a damper (63) that applies load to the link unit (30).

[0112] According to the vehicle door opening and closing operation device configured as described above [5], the swaying of the linkage unit when the linkage unit swings and the cover member moves is suppressed by the damper. As a result, the cover member can move smoothly.

[0113] [6] According to the vehicle door opening and closing operation device described in [3] above, wherein,

[0114] It has a damper (63) that applies load to the link unit (30).

[0115] According to the vehicle door opening and closing operation device configured as described above [6], the swaying of the linkage unit when the linkage unit swings and the cover member moves is suppressed by the damper. As a result, the cover member can move smoothly.
