Description

  The present invention relates to a vehicle door check structure.

  As a conventional vehicle door check structure, a check arm is formed with a check pattern at the time of opening the door and a check pattern at the time of closing the door so that the operation feeling is different between when the door is open and when the door is closed. (For example, Patent Document 1).

JP 2000-203262 A

  However, in the structure of Patent Document 1, the check pattern once set cannot be changed, and the operation feeling may not match the user's preference.

  Therefore, an object of the present invention is to obtain a vehicle door check structure that can change the operational feeling of opening and closing the door.

  In the present invention, the check arm is engaged with or fixed to the base portion held by the vehicle body member, and the posture with respect to the base portion can be variably set in the circumferential direction with respect to the longitudinal axis of the check arm. And a pattern forming portion in which a plurality of check patterns are arranged on the side surface in the circumferential direction, and the resistor assembly is applied by variably setting the posture of the pattern forming portion with respect to the base portion in the circumferential direction. The most important feature is that the check pattern for causing resistance by moving relative to each other while being in contact can be variably set.

  According to the present invention, it is possible to change the operational feeling of opening and closing the door by changing the check pattern.

FIG. 1 is a perspective view of a vehicle door check structure according to an embodiment of the present invention. 2 is a cross-sectional view taken along the line II-II in FIG. 3 is a cross-sectional view taken along the line III-III in FIG. 4 is a cross-sectional view taken along the line IV-IV in FIG. FIG. 5 is a cross-sectional view (a cross-sectional view in a cross section orthogonal to the longitudinal axis of the check arm) of the resistor assembly and a part of the check arm of the vehicle door check structure according to the embodiment of the present invention. .

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the figure, UP is the upper side of the vehicle, LD is the longitudinal direction of the check arm (axial direction of the longitudinal axis), SD is the circumferential direction with respect to the longitudinal axis of the check arm, and RD is the longitudinal axis of the check arm. The radial direction is shown.

  A vehicle door check structure 1 according to the present embodiment is attached to a check arm 2 that is formed in an elongated rod shape and has one end in the longitudinal direction LD held by a bracket 3 as a vehicle body member, and a vehicle door (not shown). And a resistor assembly 5 that moves relative to the check arm 2 in the longitudinal direction LD while abutting the check arm 2 in accordance with the opening or closing operation of the vehicle door.

  The bracket 3 is fixed to a vehicle body skeleton member such as a pillar, and includes an attachment base portion 31 and a protrusion 32 that protrudes from the attachment base portion 31 in a substantially right angle direction. A substantially circular through hole 31a is formed in the mounting base portion 31, and a bolt inserted through the through hole 31a is screwed to the vehicle body skeleton member, whereby the mounting base portion 31 is connected to the vehicle body skeleton member. It is supposed to be attached to.

  The protruding portion 32 includes a pair of upper and lower horizontal wall portions 32a and a vertical wall portion 32b that connects between side edges of the horizontal wall portion 32a. Each horizontal wall portion 32a is formed with a substantially circular through hole 62 that faces in the vertical direction. As shown in FIG. 2, a spherical body 61 is interposed between the pair of upper and lower horizontal wall portions 32 a, and the spherical body 61 is sandwiched between edges 62 a of the through holes 62. However, the holding force of the spherical body 61 by the edge 62a is set relatively moderately, so that the spherical body 61 can rotate around the central axis Ax1 of the through hole 62. The spherical body 61 is solidified to the check arm 2 (the core member 21). Therefore, in this embodiment, the spherical body 61 and the through-hole 62 constitute the rotation holding mechanism 6 for the check arm 2.

  The check arm 2 includes an elongated core member 21 and a tubular member 22 provided so as to cover the periphery of the core member 21.

  The core member 21 is formed in a round bar shape (elongated cylindrical shape) having a substantially circular cross section, and a spherical body 61 is fixed to one end portion 21a in the longitudinal direction LD by welding or the like. In the present embodiment, the core member 21 corresponds to the base portion. In the figure, the central axis (longitudinal axis) of the core member 21 is indicated as Ax2.

  A substantially cylindrical inner peripheral surface 22a that accommodates the core member 21 in an inscribed state is formed inside the tubular member 22, while the outer periphery (on the side surface 22b) of the tubular member 22 is mutually back. The check pattern 4 (4A, 4B) is formed as two pairs of opposite belt-shaped uneven surfaces, and as shown in FIGS. 3 and 4, the cross section of each part on the outer periphery is formed in a substantially rectangular shape. That is, in this embodiment, the tubular member 22 corresponds to a pattern forming portion, and a plurality of check patterns 4A and 4B are formed side by side along the circumferential direction SD on the side surface 22b. In the present embodiment, the check patterns 4A and 4A and the check patterns 4B and 4B that make a pair opposite to each other are symmetrical with respect to a virtual plane including the axis Ax2 in the longitudinal direction LD (center). Although the shape is the same when rotated 180 ° around the axis Ax2, these do not necessarily have to be symmetrical (the same shape when rotated 180 °).

  In this embodiment, the attitude of the tubular member 22 relative to the core member 21 can be variably set in the circumferential direction SD. Specifically, four arms 71 (71a, 71b) are projected in a substantially cross shape toward one end 22c in the longitudinal direction LD of the tubular member 22 toward the outside in the radial direction RD, while the lateral wall 71a From both sides (or one side) in the width direction, sandwiching arms 72 each having a substantially U-shaped cutout 72a are provided along the longitudinal direction LD. The tubular member 22 can be rotated around the core member 21 along the circumferential direction SD. Accordingly, the user first moves the tubular member 22 along the longitudinal direction LD so as to pull out the arm 71 from the notch 72a (upper right direction in FIG. 1 and right direction in FIG. 2), and then the core member 21. The posture of the tubular member 22 with respect to the core member 21 is variable in the circumferential direction SD by selectively switching the arms 71 (71a, 71b) that are pivoted around the circumferential direction SD and clamped by the clamping arm 72. Can be set. In the present embodiment, when the arm 71a extending in the lateral direction in FIG. 1 is engaged with the sandwiching arm 72, the check pattern 4A disposed at the top and bottom at that time is effective, and the arm extending in the vertical direction in FIG. In a state where 71b is engaged with the clamping arm 72, the check pattern 4B arranged at the top and bottom at that time is effective. In such a configuration, it is possible to make it easier for the user to recognize the effective check pattern 4 by attaching marks (characters, symbols, etc.) to the arms 71a and 71b. As described above, in this embodiment, the tubular member 22 is attached to the core member 21 by the engagement between the arm 71 as the first engagement portion and the sandwiching arm 72 as the second engagement portion. The engagement mechanism 7 that engages in the circumferential direction SD is formed, and the effective check pattern 4 can be changed by switching the engagement state.

  Here, in the present embodiment, the tubular member 22 is provided with an arm 71 projecting in the radial direction RD, and this arm 71 can be used as a handle when changing the posture of the tubular member 22. It can also be used as a first engaging portion that engages with the holding arm 72 as the second engaging portion. Therefore, compared with the case where these are comprised separately, it can comprise more compactly.

  In the present embodiment, the end plate 23 is attached to the other end portion 21b of the core member 21 in the longitudinal direction LD by using a fixture 25 such as a C ring. A coil spring 24 as an elastic member is interposed between the end plate 23 and the tubular member 22, and the arm 71 is attached to the inner side of the notch 72 a (the bracket) with respect to the tubular member 22 by the coil spring 24. A biasing force in a direction of pushing toward the side close to 3 and the base side of the check arm 2) is applied. In other words, in this embodiment, the engagement by the engagement mechanism 7 is difficult to be released by the urging force of the coil spring 24 as an elastic member. The coil spring 24 is externally mounted on the core member 21.

  Further, in the present embodiment, a tip member 22d having a substantially cross-shaped cross section is fixed to the other end side in the longitudinal direction LD of the tubular member 22 (the side far from the bracket 3 and the tip side of the check arm 2). An interposing member 26 having a substantially C-shaped cross section can be fitted between the member 22d and the end plate 23. Therefore, when changing the attitude of the tubular member 22 in the circumferential direction SD with respect to the core member 21, the intervention member 26 is pulled out and removed outside in the radial direction RD, and after setting the predetermined attitude as described above, By inserting the interposition member 26 inside the radial direction RD and interposing it, the state where the clamping arm 72 is arranged on the back side of the notch 72a is maintained, and the engagement by the engagement mechanism 7 is not released. Can be.

  The resistor assembly 5 is attached to an end wall portion (an end wall portion facing the mounting surface of the bracket 3) of a panel of a vehicle door (not shown). It penetrates through the assembly 5 and enters the panel of the vehicle door. The resistor assembly 5 relatively moves along the longitudinal direction LD of the check arm 2 as the vehicle door is opened and closed (in FIG. 1, the opening direction is indicated by OP and the closing direction is indicated by CL). A resistance is generated with respect to opening and closing of the door, and the operational feeling is changed according to the opening and closing position. In the case of the vehicle door that rotates about the rotation axis Ax1 as in the present embodiment, generally, the check arm 2 is moved from the vehicle door according to the opening operation (movement in the opening direction OP) of the vehicle door. In order to advance, the resistor assembly 5 moves relative to the check arm 2 along the longitudinal direction LD so as to be separated from the bracket 3, while the vehicle door is closed (moving in the closing direction CL). Accordingly, since the check arm 2 enters the vehicle door, the resistor assembly 5 moves relative to the check arm 2 along the longitudinal direction LD so as to be close to the bracket 3.

  Further, in the present embodiment, as shown in FIGS. 2 and 5, the case 51 of the resistor assembly 5 is formed by joining a case 51 a having a cross-sectional hat shape and a plate-like case 51 b, A substantially rectangular parallelepiped internal space is formed, and an urging member 53 made of an elastic member such as rubber and a contact member 52 pressed against the check arm 2 by the urging member 53 are accommodated in the internal space. is there. The case 51 is formed with a through hole 51c that allows the check arm 2 to pass therethrough. The abutting member 52 is urged in a direction approaching each other by two urging members 53 provided on the upper and lower sides, and the check arm 2 is sandwiched between the two abutting members 52 in the vertical direction. Therefore, in the present embodiment, the check pattern 4 arranged vertically (check pattern 4A in FIGS. 1 and 2) is effective, and corresponds to the unevenness of the effective check pattern 4 when the vehicle door is opened and closed. Resistance will be obtained. As shown in FIGS. 3 and 4, the protruding amount of the check pattern 4 is changed depending on the position in the longitudinal direction LD, and in the portion where the protruding amount of the check pattern 4 is large, the opening and closing operations of the vehicle door are performed. In the portion where the resistance increases and the protrusion amount is small, the resistance of the opening and closing operations of the vehicle door decreases.

  In the present embodiment, as described above, the effective check pattern 4A that is pinched by the contact member 52 and generates resistance by variably setting the attitude of the tubular member 22 in the circumferential direction SD with respect to the core member 21. , 4B can be changed to change the operational feeling of the vehicle door. That is, according to the present embodiment, it is possible to change the position (timing) at which resistance occurs when opening and closing the vehicle door, the magnitude of resistance, the degree of increase or decrease in resistance, and the like. In this embodiment, since two check patterns 4A and 4B are set, two kinds of operation feelings can be selected.

  Further, in the present embodiment, the tubular member 22 and the resistor assembly 5 are guided to each other along the relative movement in the longitudinal direction LD thereof, whereby the core of the tubular member 22 is obtained. A guide mechanism 8 that can reduce the deviation of the circumferential direction SD with respect to the member 21 is provided. Specifically, a concave groove 52b corresponding to the cross-sectional shape (substantially rectangular in this embodiment) of the protrusion 22e of the tip member 22d is formed on the contact surfaces 52a of the two contact members 52, and the check is performed. When the resistor assembly 5 moves relative to the arm 2, the protrusion 22e is accommodated in the concave groove 52b and is moved in the longitudinal direction LD while being guided by the concave groove 52b. In this configuration, when the attitude of the tubular member 22 in the circumferential direction SD with respect to the resistor assembly 5 is deviated, the protrusion 22e and the inner surface of the groove 52b abut each other, and the protrusion 22e and the resistor assembly are in contact with each other. 5 is engaged in the circumferential direction SD, and the posture is corrected. With this configuration, even if the tubular member 22 is deviated from a predetermined posture with respect to the core member 21, the posture can be corrected by reducing the deviation. That is, in the present embodiment, the guide mechanism 8 is configured by the protrusion 22e and the concave groove 52b.

  Furthermore, in the present embodiment, the engagement mechanism 7 described above also functions as a guide in the circumferential direction. Therefore, the guide mechanism 8 and the engagement mechanism 7 can more reliably shift the posture of the tubular member 22 relative to the resistor assembly 5. Can be suppressed.

  As described above, in the present embodiment, the check arm 2 is engaged with or fixed to the core member 21 as the base portion and the core member 21, and the posture with respect to the core member 21 is changed to the longitudinal direction LD of the check arm 2. And a tubular member 22 serving as a pattern forming portion formed by arranging a plurality of check patterns 4A and 4B side by side in the circumferential direction SD on the side surface 22b. By variably setting the posture of the member 22 with respect to the core member 21 in the circumferential direction SD, it is possible to variably set the check patterns 4A and 4B that cause the resistor assembly 5 to move relative to each other while abutting and generate resistance. That is, according to this embodiment, the check pattern 4A, 4B can be changed to change the operational feeling of door opening and closing.

  Further, in the present embodiment, an arm 71 as a first engagement portion provided on the tubular member 22 and a holding arm 72 as a second engagement portion provided on the bracket 3 and engaged with the arm 71 are provided. In addition, an engagement mechanism 7 that engages the tubular member 22 with the core member 21 in the circumferential direction is provided, and the arm 71 protrudes in the radial direction RD with respect to the axis Ax2 in the longitudinal direction LD. Therefore, by changing the posture of the tubular member 22 with respect to the core member 21 by holding the arm 71, the posture changing operation can be performed more easily. Further, by sharing the gripping part and the engaging part, the configuration can be made more compact than when these parts are formed separately.

  In the present embodiment, the engagement mechanism 7 is configured by the arm 71 provided on the tubular member 22 and the clamping arm 72 provided on the bracket 3 as the vehicle body member. In this way, by configuring the tubular member 22 as the pattern forming portion to be engaged with the bracket 3 as the vehicle body member, the engagement mechanism 7 can be easily formed large in the radial direction. 7 can be easily increased in rigidity and strength.

  In the present embodiment, at least one of the tubular member 22 and the resistor assembly 5 is associated with the relative movement in the axial direction (that is, the longitudinal direction LD) of the longitudinal direction LD with respect to the central axis Ax2. The guide mechanism 8 for reducing the deviation of the posture with respect to the resistor assembly 5 is provided. The guide mechanism 8 can suppress the deviation of the attitude of the tubular member 22 with respect to the core member 21.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above embodiments, and various modifications can be made. For example, in the above-described embodiment, the configuration in which the pattern forming portion is engaged with the vehicle body member has been illustrated.

  Further, the shape, number, arrangement, etc. of the check pattern can be variously changed. In addition, the configurations of the base portion, the pattern forming portion, the engagement mechanism, the first engagement portion, the second engagement portion, the rotation holding mechanism, the guide mechanism, and the like are not limited to the above embodiment, and various Can be modified. Further, the rotation holding mechanism may have a configuration other than the ball joint (for example, a bearing or a hinge mechanism).
