Abstract
The invention provides a door edge protector device (1) comprising: a drive mechanism (32) configured to move the protector (31); and a connecting mechanism (41) for connecting the protector (31) to the movable member (39) of the drive mechanism (32). The coupling mechanism (41) includes a recess (37a) and an outer cylindrical portion (42a) for rotatably holding the protector (31) on the movable member (39) about the rotation axis. The breakable stopper (43d) of the clip (43) prevents the protector (31) from rotating in the direction of rotation (R2) against a predetermined load that causes the protector (31) to rotate about the rotation axis (alpha) in the direction of rotation (R2) that is the direction of separation from the door edge. The weak portion (43j) of the breakable stopper portion (43d) is broken against an overload exceeding a predetermined load to allow rotation of the protector (31) in the direction of rotation (R2).
Description
Technical Field
The present invention relates to door edge protector devices.
Background
A door edge protector device for a vehicle disclosed in U.S. patent No. 8,826,596 includes: the door opening/closing device includes a movable protector, a drive mechanism for driving the protector, and an input unit for mechanically transmitting the opening/closing state of the door to the drive mechanism. The protector moves along a predetermined trajectory in conjunction with the opening and closing operation of the vehicle door in order to protect the door edge only when the vehicle door is opened. The door edge is an edge of an end (front end side end) opposite to a hinge side end, of both ends in the longitudinal direction of the rotary vehicle door.
Us patent No. 8,826,596 does not disclose how the protector is secured to the drive mechanism. For example, when the protector is fixed to the tip of a movable member (for example, a link) provided in the drive mechanism by a screw, if a load acts on the protector, the tip of the movable member may be damaged. When the tip of the movable member is damaged, the movable member needs to be replaced, which is troublesome and cannot be easily performed.
Disclosure of Invention
The invention aims to provide a door edge protector device which can prevent a movable component of a driving mechanism from being damaged even if overload is applied to a protector.
One aspect of the present invention provides a door edge protector apparatus comprising: a protector for covering and protecting an edge of a vehicle door, i.e., a door edge; a driving mechanism configured to move the protector along a trajectory including a storage position corresponding to a closed state of the door and an installation position covering an edge of the door corresponding to an open state of the door; and a connecting mechanism for connecting the protector to a movable member of the drive mechanism; the connecting mechanism includes: a holding portion that holds the protector to the movable member so as to be rotatable about a rotation axis; a1 st stopper configured to stop rotation of the protector in a1 st rotation direction with respect to a predetermined load that rotates the protector about the rotation axis in the 1 st rotation direction, which is a direction away from the door edge; and a1 st weak portion configured to break the 1 st stopper portion so as to allow the 1 st rotation direction of the protector to rotate in response to an overload exceeding the predetermined load.
When an overload for rotating the protector in the 1 st rotation direction is applied to the protector, the 1 st fragile portion is broken, and further rotation of the protector in the 1 st rotation direction is allowed. As a result, the movable member can be prevented from being damaged due to an overload acting on the protector to rotate the protector in the 1 st rotation direction.

Detailed Description
Embodiments of the present invention will be described below with reference to the drawings.
In the following description, a side of both ends of the rotary vehicle door in the longitudinal direction close to the hinge may be referred to as a hinge-side end portion, and an end portion opposite to the hinge-side end portion may be referred to as a distal-side end portion. In addition, the edge of the distal end may be referred to as a door edge.
An orthogonal coordinate system (XYZ coordinate system) shown in the figure is fixedly set with respect to the vehicle door. That is, when the vehicle door rotates, the orthogonal coordinate system also rotates.
The X-axis represents the longitudinal direction of the vehicle door. The arrow on the X axis indicates a direction toward the tip end (including the door edge). Hereinafter, the direction of the arrow on the X axis is sometimes referred to as the + X direction, and the opposite direction is sometimes referred to as the-X direction. That is, -X direction means a direction toward the hinge side end. In some cases, the + X direction and the-X direction are collectively referred to as the X direction.
The Y-axis represents the width direction of the vehicle door. The arrow on the Y axis indicates a direction toward the widthwise outer side of the vehicle door. Hereinafter, the direction of the arrow on the Y axis is sometimes referred to as the + Y direction, and the opposite direction is sometimes referred to as the-Y direction. That is, the-Y direction indicates a direction toward the inside in the width direction of the vehicle door. In some cases, the + Y direction and the-Y direction are collectively referred to as the Y direction.
The Z-axis represents the height direction of the vehicle door. The arrow on the Z axis indicates a direction toward the height direction upper side of the vehicle door. Hereinafter, the direction of the arrow on the Z axis is sometimes referred to as the + Z direction, and the opposite direction is sometimes referred to as the-Z direction. That is, the-Z direction indicates a direction toward the height direction lower side of the vehicle door. In some cases, the + Z direction and the-Z direction are collectively referred to as the Z direction.
When the vehicle door is in the closed position, the X direction represents the vehicle length direction, the Y direction represents the vehicle width direction, and the Z direction represents the vehicle height direction.
Referring to fig. 1, a door edge protector device 1 includes an input unit 2, an output unit 3, and a cable (transmission element) 4. The input unit 2 is accommodated in the vicinity of the hinge-side end portion of the vehicle door, and the output unit 3 is accommodated in the vicinity of the front-end-side end portion of the vehicle door. The entire cable 4 is housed inside the vehicle door, and mechanically couples the input unit 2 and the output unit 3.
The input unit 2 detects an open-closed state of a vehicle door. The open/close state of the vehicle door detected by the input unit 2 is mechanically transmitted to the output unit 3 through the cable 4. Specifically, when the vehicle door is closed, the front end of the plunger 22 of the input unit 2 is pushed into the housing 21 by the vehicle body as indicated by arrow a 1. When the plunger 22 is at the push-in position, the input unit 2 pulls the inner wire of the wire 4 from the output unit 3. On the other hand, if the vehicle door is in the open state, the plunger 22 moves linearly in a direction protruding from the housing 21 as indicated by an arrow a 2. When the plunger 22 is in the protruding position, the input unit 2 sends out the inner wire of the wire 4 to the output unit 3.
Referring to fig. 1 and 2, the output unit 3 includes: a protector 31 for covering the door edge for protection; a drive mechanism 32 that holds and moves the protector 31; and a housing 33 that houses the drive mechanism 32.
The protector 31 includes: a protector body 34 for covering the door edge; and a bracket 35 to which the protector main body 34 is fixed. The bracket 35 includes: a holder main body 36 extending in the Z direction along the protector main body 34; and a coupling portion 37 for coupling to a movable member 39 of the drive mechanism 32. The holder main body 36 and the coupling portion 37 are coupled by an arm portion 38. In the present embodiment, the holder 35 is made of resin.
The drive mechanism 32 includes a movable member 39 (e.g., a link) protruding from the housing 33. In the present embodiment, the movable member 39 is made of resin. A connecting portion 37 of the protector 31 is connected to the tip of the movable member 39. The drive mechanism 32 is configured to: the protector 31 is moved in accordance with pulling and sending out of the inner cable by the input unit 2, that is, in accordance with the open/close state of the vehicle door detected by the input unit 2. Specifically, the movable member 39 is moved in the X direction and the Y direction so that the protector 31 moves along a trajectory including a storage position P1 corresponding to the closed state of the vehicle door and a set position P2 covering the door edge corresponding to the open state of the vehicle door, as indicated by a two-dot chain line T in fig. 2. The drive mechanism 32 may be constituted by a combination of elements such as a cam, a cam follower, a pinion, a rack, and a spring. The specific configuration of the drive mechanism 32 is not particularly limited.
Next, referring to fig. 3 to 10, a coupling mechanism 41 for coupling the protector 31 to the movable member 39 will be described. As best shown in fig. 7 and 8, the coupling mechanism 41 in the present embodiment includes: a connecting portion 37 of the protector 31, a base portion 42 provided at the tip of the movable member 39, a clip 43, and a torsion coil spring 44. In the present embodiment, the clip 43 is made of resin.
The coupling mechanism 41 includes a holding portion 45, and the holding portion 45 supports the protector 31 to the movable member 39 so as to be rotatable about a rotation axis α extending in the Z direction. The holding portion 45 includes the coupling portion 37 of the protector 31 and the base portion 42 of the movable member 39. The structure of the holding portion 45 will be described below.
Referring to fig. 4, 7, and 9, the base portion 42 of the movable member 39 includes an outer cylindrical portion (1 st protruding shaft portion) 42a protruding in the + Z direction (upward). The proximal end of the outer cylindrical portion 42a is closed, and the distal end of the outer cylindrical portion 42a is open. The base portion 42 of the movable member 39 includes an inner cylindrical portion (2 nd protruding shaft portion) 42b, and the inner cylindrical portion 42b is provided inside the outer cylindrical portion 42a and similarly protrudes in the + Z direction (upward). The upper and lower ends of the inner cylindrical portion 42b are open.
On the other hand, referring to fig. 4, 8, and 10, a substantially circular recess 37a that opens in the-Z direction (downward) is formed in the coupling portion 37 of the protector 31. An annular rib 37c is provided on the ceiling wall 37b of the recess 37 a. Referring to fig. 3 to 6 and 10, an outer cylindrical portion 42a and an inner cylindrical portion 42b are inserted into the recess 37a from below. Further, the inner cylindrical portion 42b is inserted inside the rib portion 37 c.
As best shown in fig. 3 to 5, the connecting portion 37 of the protector 31 is supported by the base portion 42 so as to cover the base portion 42 of the movable member 39 from above. Referring to fig. 4, the top wall 37b of the recess 37a is supported by the distal end surface of the outer cylindrical portion 42 a. The circumferential wall of the recess 37a is in sliding contact with the side circumferential surface of the outer cylindrical portion 42a, and the inner circumferential surface of the rib 37c is in sliding contact with the side circumferential surface of the inner cylindrical portion 42 b. Thus, as indicated by reference numerals R1 and R2, the coupling portion 37 of the protector 31 is supported or held by the base portion 42 of the movable member 39 so as to be rotatable about a rotation axis α extending in the Z direction.
Referring to fig. 4 and 9, the torsion coil spring 44 includes: a spiral portion 44a formed by winding a linear elastic material a plurality of times; and a pair of end portions 44b, 44c, which are 1 thread-like elastic material extending from the spiral portion 44a, respectively. The spiral portion 44a is attached to the inner cylindrical portion 42b provided in the base portion 42 of the movable member 39, and is disposed in a cylindrical space defined by the inner cylindrical portion 42b, the outer cylindrical portion 42a, and the outer cylindrical portion. One end 44b of the torsion coil spring 44 is linear and extends in the radial direction of the coil portion 44a, and is locked to the base portion 42 of the movable member 39. Specifically, the end 44b of the torsion coil spring 44 is locked in a narrow slit 42c, and the slit 42c is formed in an outer cylindrical portion 42a of the base portion 42. The other end 44c of the torsion coil spring 44 has: a linear portion 44d extending in the radial direction of the spiral portion 44 a; and a portion 44e bending the portion in the-Z direction. The end portion 44c is locked to the coupling portion 37 of the protector 31. Specifically, the portion 44d of the end portion 44c protrudes outward from the outer cylindrical portion 42a through the wide slit 42d formed in the outer cylindrical portion 42a of the pedestal portion 42. As shown in fig. 8 and 10, a recess 37d is partially formed in a peripheral wall 37m of a recess 37a provided in the coupling portion 37 of the protector 31. A portion 44e of the end portion 44c of the torsion coil spring 44 is accommodated in the recess 37d, and abuts on one end wall of the recess 37d by the elasticity of the torsion coil spring 44 itself.
As described above, the one end 44b of the torsion coil spring 44 is locked to the movable member 39 and the other end 44c is locked to the protector 31, whereby the protector 31 is elastically biased in the rotational direction (2 nd rotational direction) indicated by the arrow R1 around the rotational axis α. The rotation direction R1 is a direction in which the protector body 34 approaches the door edge. A rotation direction R2 (1 st rotation direction) opposite to the rotation direction R1 is a direction in which the protector main body 34 is separated from the door edge.
Referring to fig. 7, 8, 11, and 12, the clip 43 includes: a substantially disk-shaped base 43 a; and a plurality of (4 in the present embodiment) engagement shafts 43b projecting upward (+ Z direction) from the center of the base portion 43 a.
The base portion 43a of the clip 43 is provided with: a rigid stopper (2 nd stopper) 43 c; and a breakable stopper (1 st stopper) 43 d. The rigid stopper portion 43c restricts the rotation of the protector 31 about the rotation axis α with respect to the movable member 39 in the rotation direction R1 (the biasing direction of the torsion coil spring 44 as described above). The fragile stopper portion 43d restricts rotation of the protector 31 about the rotation axis α in the rotation direction R2 with respect to the movable member 39.
The rigid stopper 43c is an arc-shaped wall portion protruding upward (+ Z direction) from the peripheral edge of the base portion 43 a. The rigid stopper portion 43c includes a pair of side surfaces 43e, 43f both extending substantially perpendicularly (in the Z direction) from the base portion. As described later, the side surface 43e locks the connection portion 37 of the protector 31, and the side surface 43f is locked by the movable member 39.
The frangible stopper 43d includes: a locking portion 43g which is an arc-shaped wall portion protruding upward (+ Z direction) from the peripheral edge of the base portion 43 a; and a sheet-like rotation preventing portion 43h extending from one end of the locking portion 43 g. A side wall portion of the locking portion 43g opposite to the rotation preventing portion 43h is an inclined wall portion 43i inclined with respect to the rotation axis α. A weak portion 43j (1 st weak portion) is provided between the locking portion 43g and the rotation preventing portion 43 h. The weak portion 43j in the present embodiment is constituted by a pair of grooves provided on the inner and outer surfaces of the breakable stopper portion 43 d. The thickness of the fragile stopper 43d at the weak portion 43j is sufficiently small compared to the thickness of the fragile stopper 43d at the other portions, i.e., the locking portion 43g and the rotation preventing portion 43 h. For example, the thickness of the fragile stopper 43d at the weak portion 43j is set to about 1/4 of the thickness of the fragile stopper 43d at the other portion.
Each engagement shaft 43b of the clip 43 has: a shaft main body 43k which is a flexible rod-shaped body protruding upward from the base portion 43 a; and an engaging portion 43m provided at the distal end of the shaft main body 43k and having a cross-sectional shape sufficiently larger than that of the shaft main body 43 k.
A circular weak portion 43r having a diameter slightly larger than that of the shaft main body 43k is provided coaxially with the shaft main body 43k at the base portion 43a of the clip 43. Further, a plurality of (6 in the present embodiment) linear weak portions 43n are provided in the base portion 43a of the clip 43. The round weak portion 43r and the weak portion 43n constitute the 2 nd fragile portion of the present invention. In the present embodiment, each weak portion 43n is formed so as to extend in the radial direction of the base portion 43a from the peripheral edge of the circular weak portion 43r to the outer edge of the base portion 43 a. The circular weak portion 43r and the weak portion 43n are constituted by a pair of grooves provided on the upper and lower surfaces of the base portion 43 a. The thickness of the round weak portion 43r and the base portion 43a at the weak portion 43n is sufficiently small compared to the thickness of the base portion 43a at the other portions. For example, the thickness of the round weak portion 43r and the base portion 43a at the weak portion 43n is set to about 1/4 of the thickness of the base portion 43a at the other portions.
As best shown in fig. 4, the clip 43 is attached to the coupling portion 37 of the protector 31 in a state where the engaging shaft 43b is inserted from below, and the coupling portion 37 of the protector 31 is covered on the base portion 42 of the movable member 39. Specifically, a recess 37e is provided in the center of the inner peripheral side of the rib 37c on the top wall 37b of the recess 37a of the protector 31. A plurality of (4 in the present embodiment) engaging projections 37f are provided on the peripheral wall of the recess 37 e. These engaging projections 37f project toward the center of the recess 37 e. The shaft main body 43k of the engagement shaft 43b of the clip 43 is inserted from below into the inner cylindrical portion 42b provided in the base portion 42 of the movable member 39. Further, the engaging portion 43m of the engaging shaft 43b is engaged with the engaging projection 37f so as to be rotatable about the rotation axis α although the linear motion along the rotation axis α is restricted. The base portion 43a of the clip 43 is disposed below the pedestal portion 42. That is, the connecting portion 37 of the protector 31 is attached to the base portion 42 of the movable member 39 by the clip 43 so as to be rotatable about the rotation axis α.
Referring to fig. 5, as described above, the coupling portion 37 of the protector 31 is elastically biased in the rotation direction R1 about the rotation axis α by the torsion coil spring 44. A1 st stopper wall portion 37g protruding downward (in the (-Z direction) substantially parallel to the rotation axis α is provided at a position near the boundary with the arm portion 38 on the outer peripheral portion of the coupling portion 37 of the protector 31. Further, a2 nd stopper wall portion 37h protruding downward (in the (-Z direction) substantially in parallel with the rotation axis α is provided at a position spaced apart from the 1 st stopper wall portion 37g on the outer peripheral portion of the coupling portion 37 of the protector 31. The first stopper wall portion 37g of the coupling portion 37 of the protector 31 is pressed against the side surface 43e of the rigid stopper portion 43c of the clip 43 and is stopped by the biasing force of the torsion coil spring 44. Although the clip 43 is rotatable about the rotation axis α as described above, the other end 43f of the rigid stopper portion 43c is pressed against the movable member 39 by the biasing force of the torsion coil spring 44 and is locked. In this way, the rigid stopper portion 43c of the clip 43 prevents or positions the coupling portion 37 of the protector 31 from rotating about the rotation axis α with respect to the base portion 42 of the movable member 39 by the elastic biasing force of the torsion coil spring 44. The 2 nd stopper wall portion 37h is pressed against the movable member 39 by the biasing force of the torsion coil spring 44 and is locked. Thereby, the connection portion 37 of the protector 31 is also prevented from rotating around the rotation axis α with respect to the base portion 42 of the movable member 39, or is positioned.
Referring to fig. 3, 6, and 8, a 3 rd stopper wall portion 37i protruding downward (-Z direction) is provided on the outer peripheral portion of the coupling portion 37 of the protector 31 at a position substantially opposite to the 1 st stopper wall portion 37 g. The side surface of the 3 rd stopper wall portion 37i is an inclined surface 37j inclined with respect to the rotation axis α.
The following description is given of the case where a load is applied to rotate the protector 31 about the rotation axis α in the rotation direction R2 against the elastic biasing force of the torsion coil spring 44. Such a load can be generated, for example, by a user holding the protector 31 in his hand and attempting to rotate the protector 31 about the rotation axis α in the rotation direction R2.
If the magnitude of the load in the rotational direction R2 is within a predetermined range, the linking portion 37 of the protector 31 is prevented from rotating by the breakable stopper portion 43d of the clip 43. Specifically, the inclined surface 37j of the 3 rd stopper wall portion 37i provided in the connection portion 37 of the protector 31 is locked to the breakable stopper portion 43d of the clip 43. More specifically, the inclined surface 37j of the 3 rd stopper wall portion 37i presses the inclined wall portion 43i provided on the locking portion 43g of the breakable stopper portion 43 d. As described above, the clip 43 is rotatable about the rotation axis α with respect to the coupling portion 37 of the protector 31 and the base portion 42 of the movable member 39. Therefore, when the locking portion 43g of the clip 43 is pressed, the rotation preventing portion 43h is pressed against the movable member 39. As a result, the locking portion 43g of the clip 43 prevents the coupling portion 37 of the protector 31 from rotating in the rotation direction R1.
When a load is further applied to rotate the protector 31 about the rotation axis α in the rotation direction R2, the inclined surface 37j of the 3 rd stopper wall portion 37i provided in the connection portion 37 of the protector 31 moves in the + Z direction along the inclination of the inclined wall portion 43i provided in the engagement portion 43g of the breakable stopper portion 43 d. That is, since the coupling portion 37 is pushed up, the engaging projection 37f pushes up the engaging portion 43m provided at the front end of the shaft main body 43k of the engaging shaft 43 b. When a load to rotate the protector 31 about the rotation axis α in the rotation direction R2 exceeds a predetermined allowable range, that is, when an overload is applied, the 3 rd stopper wall portion 37i provided in the connection portion 37 of the protector 31 presses the inclined wall portion 43i of the clip 43 in the rotation direction R2. Since the inclined wall portion 43i is pressed, the rotation blocking portion 43h is strongly pressed against the movable member 39 of the drive mechanism 32 in the rotation direction R2. As a result, the breakable stopper 43d is broken at the weakened portion 43 j. Specifically, the breakable stopper 43d is broken at the portion of the weak portion 43j, and the rotation preventing portion 43h is detached from the clip 43. Since the rotation restricting portion 43h is disengaged from the clip 43 and the restriction of the rotation of the clip 43 in the rotation direction R2 is released, the protector 31 further rotates in the rotation direction R2 around the rotation axis α from the rotation angle position before the weak portion 43j is broken. When an overload is applied to the protector 31 in this way, the breakable stopper 43d of the clip 43 is broken, and further rotation of the protector 31 is allowed. As a result, the movable member 39 can be prevented from being damaged due to an overload applied to the protector 31. Since the protector 31 is allowed to rotate in the rotation direction R2 by the breakable stopper 43d being broken, the user can visually recognize the breakage of the clip 43. Further, a breakage sound is generated by the impact of the breakage of the breakable stopper 43d, and the user can audibly recognize the breakage of the clip 43.
When a load for rotating the protector 31 about the rotation axis α in the rotation direction R2 is further applied even if the breakable stopper 43d breaks, the inclined surface 37j of the 3 rd stopper wall portion 37i provided in the connection portion 37 of the protector 31 further moves in the + Z direction along the inclination of the inclined wall portion 43i provided in the locking portion 43g of the breakable stopper 43 d. Thus, the engagement projection 37f further pushes up the engagement portion 43m provided at the tip end of the shaft main body 43k of the engagement shaft 43b, and the shaft main body 43k is broken by the circular weak portion 43r formed on the base portion 43a, and the protector 31 is separated from the movable member 39 because the shaft main body 43k is detached from the base portion 43 a. In this case, the base portion 43a of the clip 43 is broken, and thus the movable member 39 can be prevented from being broken due to an overload applied to the protector 31. The following structure is adopted: when an overload is applied to the protector 31 to rotate about the rotation axis α in the rotation direction R2, the circular weak portion 43R is easily broken by forming the weak portion 43n continuous with the circular weak portion 43R.
By replacing the clip 43 having the broken weak portion 43j with a new clip 43, the door edge protector device 1 can be easily restored to the state before an overload is applied to the protector 31. The broken clip 43 is removed, for example, in the following order. A tool is inserted through an opening 37k provided in the coupling portion 37 of the protector 31, and the engagement between the engagement portion 43m of the engagement shaft 43b and the engagement projection 37f of the coupling portion 37 is released. After the engagement is released, the clip 43 can be detached by pulling out the engaging shaft 43b from the inner cylindrical portion 42 b. Even when the clip 43 is not broken, the clip 43 can be removed in the same procedure. If the clip 43 is forcibly detached without following the normal procedure, an overload is applied to the base portion 43a of the clip 43. Due to the overload, the base portion 43a may be broken at the weak portion 43 n. In other words, if not in the regular order, the clip 43 cannot be detached as long as the clip 43 is not broken.
In the present embodiment, a recess 37e is provided in the recess 37a of the coupling portion 37 of the protector 31, and the recess 37e has a top surface provided with an opening 37 k. However, the top surface of the recess 37e may be eliminated, and the engaging portion 43m of the engaging shaft 43b may be exposed to the outside from the coupling portion 37 by using the engaging projection 37f provided on the peripheral wall of the recess 37e as the uppermost portion of the coupling portion 37.
