Description

  The present invention relates to a hinge device used for an automobile door, and more particularly to a hinge device whose opening angle can be set large by rotating the door about two axes.

  As this type of hinge device, for example, those disclosed in Patent Documents 1 and 2 are known.

  In these hinge devices, both ends of the hinge arm are pivotally supported about the first axis and the second axis with respect to the hinge bases attached to the vehicle body side and the door side, respectively. Then, by rotating the door about the first axis and the second axis, the opening angle of the door can be set as large as about 270 degrees.

  Such a hinge device is provided with a link mechanism for switching between a time when the door rotates about the first axis and a time when the door rotates about the second axis. This link mechanism is configured to operate in accordance with changes in the relative positions of the hinge base on the vehicle body side, the hinge base on the door side, and the hinge arm, and the door rotates around the first axis. At the time of switching between the timing and the rotation timing of the door around the second axis, an activation force that acts as an operation trigger is applied. For example, when the door is opened, when the door is rotated by a predetermined angle about the first axis and then rotated about the second axis, the former rotation timing is shifted to the latter rotation timing. Sometimes an activation force is applied to the link mechanism.

  In the hinge device described in Patent Document 1, the starting force of such a link mechanism is given by an adjustment screw provided on one of the hinge base on the vehicle body side and the door side coming into contact with the hinge arm. That is, due to the contact, the relative rotation of one hinge base and the hinge arm is prevented, and instead, the other hinge base and the hinge arm rotate relative to each other. The link mechanism is activated by the rotational force. That is, the starting force of the link mechanism is indirectly applied to the link mechanism by the adjustment screw provided on the hinge base restraining the movement of the hinge arm.

  Moreover, in the hinge apparatus of patent document 2, the spring for urging | biasing a link mechanism to a specific operation | movement direction is provided, and starting force is added to a link mechanism with the spring.

  The hinge device of this example includes a first hinge base 10 attached to the vehicle body 1 side, a second hinge base 20 attached to the door 2 side, and a hinge arm 30 that connects between them. As shown in FIG. 1, the first hinge base 10 is formed in a substantially U-shaped cross section having an upper surface portion 10A, a side surface portion 10B, and a lower surface portion 10C. Similarly, the second hinge base 20 is also an upper surface portion 20A. , The side surface portion 20B and the lower surface portion 20C are formed in a substantially U-shaped cross section. As shown in FIG. 1, the hinge arm 30 is formed in a substantially U-shaped cross section having an upper surface portion 30A, a side surface portion 30B, and a lower surface portion 30C, and is formed in a substantially plane U-shape as shown in FIG. .

  A first shaft 31 penetrating the upper surface portion 30A and the lower surface portion 30C on one end side of the hinge arm 30 is spanned between the upper surface portion 10A and the lower surface portion 10C of the first hinge base 10. One end of the first shaft 31 is pivotally supported by the first hinge base 10 about the first shaft 31. When the opening angle of the door 2 is between 0 degrees and 90 degrees, as will be described later, one end of the hinge arm 30 rotates about the first shaft 31 in the directions of arrows A1 and A2 (FIGS. 2 and 3). reference). On the other hand, a second shaft 32 penetrating the upper surface portion 30A and the lower surface portion 30C on the other end side of the hinge arm 30 is spanned between the upper surface portion 20A and the lower surface portion 20C of the second hinge base 20. The other end of the hinge arm 30 is pivotally supported on the second hinge base 20 around the second shaft 32. When the opening angle of the door 2 is between 90 degrees and 170 degrees, the other end of the hinge arm 30 rotates about the second shaft 32 in the directions of arrows B1 and B2, as will be described later (FIGS. 3 and 4).

  On the upper side of the hinge arm 30, a time when the relative rotation between the first hinge base 10 around the first shaft 31 and one end of the hinge arm 30 is allowed, and a second around the second shaft 32. A link mechanism 50 is provided for setting the relative timing of allowing relative rotation between the hinge base 20 and the other end of the hinge arm 30. Further, on the lower side of the hinge arm 30, a predetermined check force is applied to the relative rotation between the first hinge base 10 and one end of the hinge arm 30 around the first shaft 31. A second check for applying a predetermined check force to the relative rotation of the first check mechanism 70, the second hinge base 20 and the other end of the hinge arm 30 about the second shaft 32. And a mechanism 80.

In the following, the configuration and operation of each of the link mechanism 50, the first check mechanism 70, and the second check mechanism 80 will be described.
(Link mechanism 50)
The link mechanism 50 includes a first control lever 51, a second control lever 52, and a link member 53 that connects them. As shown in FIG. 1, the first control lever 51 is pivotally supported by the shaft 54 on the upper surface 30A on one end side of the hinge arm 30 and is rotatable in the directions of arrows C1 and C2 in FIG. Similarly, the second control lever 52 is pivotally supported on the upper surface 30A on the other end side of the hinge arm 30 by a shaft 55, and is rotatable in the directions of arrows D1 and D2 in FIG. One end of a link member 53 is relatively pivotally connected to the first control lever 51 by a shaft 56, and the other end of the link member 53 is relatively pivoted by a shaft 57 to the second control lever 52. It is connected freely.

  As shown in FIG. 5, the first control lever 51 is formed with a cam follower portion 51 </ b> A that faces the cam surface of the first cam 61 provided on the first hinge base 10. A cam follower portion 52A that faces the second cam 62 provided on the second hinge base 20 is formed. In the case of this example, the first cam 61 is fixed on the same axis as the first shaft 31, and the second cam 62 is fixed on the same axis as the second shaft 32. The cam surface of the first cam 61 is formed with a raised portion 61A, a protrusive portion 61B, and a stepped portion 61C located between them. Similarly, on the cam surface of the second cam 62, A raised portion 62A, a protrusive portion 62B, and a stepped portion 62C positioned therebetween are formed.

  In the link mechanism 50, the relative positions of the first control lever 51, the second control lever 52, and the hinge arm 30 change according to the opening angle of the door 2 as shown in FIGS. 5, 6, and 7. Therefore, the operation is as follows.

  First, as shown in FIG. 5, the cam follower portion 51 </ b> A of the first control lever 51 extends along the raising portion 61 </ b> A of the first cam 61 until the opening angle reaches 0 to nearly 90 degrees by the opening operation of the door 2. To move the hinge arm 30 around the first shaft 31 in the arrow A1 direction. Further, at this time, as shown in FIG. 5, the cam follower portion 52A of the second control lever 52 hits the stepped portion 62C of the second cam 62, and the rotation of the hinge arm 30 about the second shaft 32 in the direction of the arrow B1. Stop movement.

  When the opening angle of the door 2 reaches nearly 90 degrees, the cam follower portion 51A of the first control lever 51 is disengaged from the starting portion 61A of the first cam 61, as shown in FIG. Rotation in the C1 direction is allowed. Therefore, the second control lever 52 can rotate in the direction of the arrow D1, and the cam follower portion 52A moves along the slope of the step portion 62C of the second cam 62. In a slight period from when the door opening angle is a little over 90 degrees to a little over 90 degrees, the first control lever 51 rotates in the direction of the arrow C1 and the second control lever 52 moves in the direction of the arrow D1. In order to rotate in the direction, the hinge arm 30 rotates in the directions of arrows A1 and B2 around the first shaft 31 and the second shaft 32, respectively.

  When the opening angle of the door 2 reaches 90 degrees, the hinge arm 30 abuts against the stopper pin 63 of the first hinge base 10 as shown in FIG. Thirty rotations in the direction of arrow A1 are prevented. As shown in FIG. 1, the stopper pin 63 is stretched between the upper surface portion 10 </ b> A and the lower surface portion 10 </ b> C of the first hinge base 10.

  After the opening angle of the door slightly exceeds 90 degrees, the cam follower portion 51A of the first control lever 51 is positioned at the protuberance portion 61B of the first cam 61, and the cam follower of the second control lever 52, as shown in FIG. The part 52 </ b> A is located at the raising part 62 </ b> A of the second cam 62. Then, the cam follower portion 52A of the second control lever 52 moves along the raising portion 62A of the second cam 62, and the rotation of the hinge arm 30 about the second shaft 32 in the direction of arrow B1 is allowed.

  When the opening angle of the door 2 reaches 170 degrees, as shown in FIG. 7, the stopper portion 20 </ b> E located on each of the upper surface portion 20 </ b> A and the lower surface portion 20 </ b> C of the second hinge base 10 and the upper surface portion 30 </ b> A of the hinge arm 30. And the stopper portion 30D positioned on each of the lower surface portions 30C contact each other, and the door 2 is prevented from opening more than 170 degrees.

  Thus, in the opening operation of the door 2, the hinge arm 30 rotates in the direction of the arrow A1 about the first shaft 31 until the opening angle reaches 0 to nearly 90 degrees, and the opening angle is After a slight period of time until 90 degrees is passed (hereinafter also referred to as “transition time”), the hinge arm 30 rotates about the second shaft 32 in the direction of the arrow B1. In other words, after the transition time after the time when the relative rotation of the first hinge base 10 and the hinge arm 30 is allowed (first rotation time), the relative relationship between the second hinge base 20 and the hinge arm 30 is reached. This is a time when second rotation is allowed (second rotation time). As a result, the pivot center of the hinge arm 30 is moved from the first shaft 31 to the second shaft 32.

  The starting force of the link mechanism 50 at such a transition time is such that when the cam follower portion 51A of the first control lever 51 is disengaged from the starting portion 61A of the first cam 61, the step portion 62C of the second cam 62 is subjected to the second control. It is given by the rotational force that rotates the lever 52 in the direction of the arrow D1.

  Next, until the opening angle of the door 2 is changed from 170 degrees to nearly 90 degrees due to the closing operation of the door 2, the cam follower portion 52A of the second control lever 52 is the raised portion of the second cam 62 as shown in FIG. It moves along 62A, and the rotation of the hinge arm 30 about the second shaft 32 in the arrow B2 direction is allowed. At this time, as shown in FIG. 7, the cam follower portion 51A of the first control lever 51 abuts against the step portion 61C of the first cam 61, and the rotation of the hinge arm 30 about the first shaft 31 in the direction of arrow A2 is performed. Stop movement.

  When the opening angle of the door 2 reaches nearly 90 degrees, as shown in FIG. 6, the cam follower portion 52A of the second control lever 52 is disengaged from the starting portion 62A of the second cam 62, and the arrow of the second control lever 52 The rotation in the D2 direction is allowed. Further, as shown in FIG. 6, a contact member (contact portion) 64 provided at a fixed position of the second hinge base 20 contacts the second control lever 52. Due to the contact force received from the contact member 64, the second control lever 52 rotates in the direction of arrow D2, and the first control lever 51 rotates in the direction of arrow C2. The first control lever 51 rotates in the direction of the arrow C2 and the second control lever 52 is moved in the direction of the arrow C2 in a short period from when the door opening angle reaches nearly 90 degrees until it slightly exceeds 90 degrees. Since the hinge arm 30 rotates in the arrow D2 direction, the hinge arm 30 rotates in the arrows A2 and B2 directions around the first shaft 31 and the second shaft 32, respectively.

  When the opening angle of the door slightly exceeds 90 degrees, the cam follower 51A of the first control lever 51 is positioned at the protuberance 61B of the first cam 61 and the cam follower of the second control lever 52 as shown in FIG. The part 52 </ b> A is located at the raising part 62 </ b> A of the second cam 62. Then, the cam follower portion 51A of the first control lever 51 moves along the raising portion 61A of the first cam 61, and the rotation of the hinge arm 30 about the first shaft 31 in the direction of arrow A2 is permitted.

  Thus, in the closing operation of the door 2, the hinge arm 30 rotates in the direction of the arrow B2 around the second shaft 32 until the opening angle of the door 2 reaches 170 degrees to nearly 90 degrees, and the opening angle After a slight period until the angle slightly exceeds 90 degrees (hereinafter also referred to as “transition time”), the hinge arm 30 rotates about the first shaft 31 in the arrow A2 direction. That is, after the transition time after the time when the second hinge base 20 and the hinge arm 30 are allowed to rotate relative to each other (second rotation time), the relative relationship between the first hinge base 10 and the hinge arm 30 is relatively long. This is a time (first rotation time) in which a general rotation is allowed. As a result, the rotation center of the hinge arm 30 is moved from the second shaft 32 to the first shaft 31.

  The starting force of the link mechanism 50 at such a transition time is given by the contact force of the contact member 64 against the second control lever 52. Thus, the abutment member 64 directly activates the link mechanism 50, so that the link mechanism 50 can be activated more reliably. In addition, the activation force can be applied to the link mechanism 50 by a very simple configuration in which the contact member 64 is fixedly provided on the second hinge base 20, and the activation force is applied using an adjustment screw or a spring. Compared to the above, it is possible to simplify the configuration of the entire hinge device and improve the productivity.

(First check mechanism 70)
The first check mechanism 70 includes a cam lever 71, a compression spring 72, and a cam roller (contact portion) 73. As shown in FIG. 8, the cam lever 71 is formed in a substantially plane L shape having one end portion 71 </ b> A, the other end portion 71 </ b> B, and the intermediate portion 71 </ b> C, and the one end portion 71 </ b> A is connected to the first hinge base 10 by the shaft 74. Are pivotally supported in the directions of arrows E1 and E2. The compression spring 72 is compressed and interposed between the other end portion 71B of the cam lever 71 and the spring receiving portion 10D of the first hinge base 10, and the cam lever 71 is urged in the direction of arrow E2 by its restoring force. ing. The cam roller 73 is rotatably attached to the lower end of a pin 75 fixed at a fixed position of the hinge arm 30. The pin 75 is connected to the upper surface portion 30A and the lower surface portion 30C of the hinge arm 30 as shown in FIG. It is spanned between.

  A cam surface 71 </ b> D that press-contacts the cam roller 73 is formed in the intermediate portion 71 </ b> C of the cam lever 71. The cam surface 71D in this example is formed long from the intermediate portion 71C to the other end portion 71B. Further, the intermediate portion 71C of the cam lever 71 is located adjacent to the compression spring 72 and extends substantially along the compression direction of the compression spring 72, that is, the vertical direction in FIG. Further, the other end 71B of the cam lever 71 is located outside the compression spring 72 when the door 2 is opened as shown in FIGS. 9 and 10, that is, below the compression spring 72 in FIGS. To position.

  The first check mechanism 70 having such a configuration applies a predetermined check force to the relative rotation of the first hinge base 10 and the hinge arm 30 around the first shaft 31. As described above, the rotation range of the hinge arm 30 around the first shaft 31 corresponds to 90 degrees, that is, the range between 0 degrees and 90 degrees of the opening angle of the door 2. As the hinge arm 30 rotates, the cam roller 73 on the hinge arm 30 side moves as shown in FIG. 11 while rolling along the cam surface 71D of the cam lever 71.

  P1 in FIG. 11 is a moving position of the cam roller 73 when the rotation angle of the hinge arm 30 around the first shaft 31 is 0 degree as shown in FIG. P3 in FIG. 11 is a moving position of the cam roller 73 when the rotation angle of the hinge arm 30 around the first shaft 31 is 90 degrees as shown in FIGS. P2 in FIG. 11 is a moving position of the cam roller 73 when the rotation angle of the hinge arm 30 around the first shaft 31 is 60 degrees. For such rotation of the hinge arm 30, a check force according to the shape of the cam surface 71 </ b> D in pressure contact with the cam roller 73 is applied. In the case of this example, a check force is applied so as to give a predetermined click feeling when the rotation angle of the hinge arm 30 is 60 degrees and 90 degrees.

  Such a first check mechanism 70 has a compression spring because the other end 71B of the cam lever 71 is located outside the compression spring 72, that is, on the exposed side when the door 2 is opened as shown in FIGS. The exposure degree of 72 can be suppressed small, and the favorable external appearance of a hinge apparatus can be maintained. Moreover, since the hinge arm 30 is also located outside the compression spring 72 when the door 2 is opened, the appearance of the hinge device can be better maintained. Further, since the intermediate portion 71C of the cam lever 71 is adjacent to the compression spring 72 and extends substantially along the compression direction of the compression spring 72, the cam lever 71 and the compression spring 72 can be efficiently arranged.

  Further, since the cam surface 71D of the cam lever 71 is formed on the side surface of the intermediate portion 71C located on the opposite side to the compression spring 72, the position of the cam roller 73 can be adjusted without particularly considering interference with the compression spring 72. It is possible to set the cam surface 71D sufficiently large. By forming the cam surface 71D to be long, the optimum checking force according to the opening angle of the door 2 can be set finely. In this example, the cam surface 71D can be formed longer because the formation range of the cam surface 71D extends to the position of the other end 71B.

  Further, since the pin 75 is stretched between the upper surface portion 30A and the lower surface portion 30C of the hinge arm 30 and the cam roller 73 is attached to the pin 75, the cam roller 73 is firmly positioned, and more accurate. Checking power can be given.

(Second check mechanism 80)
The second check mechanism 80 includes a cam lever 81, a compression spring 82, and a cam roller (contact portion) 83. As shown in FIG. 8, the cam lever 81 is formed in a substantially plane L shape having one end portion 81 </ b> A, the other end portion 81 </ b> B, and the intermediate portion 81 </ b> C, and the one end portion 81 </ b> A is connected to the second hinge base 20 by the shaft 84. Are pivotally supported in the directions of arrows F1 and F2. The compression spring 82 is compressed and interposed between the other end portion 81B of the cam lever 81 and the spring receiving portion 20D of the second hinge base 20, and the cam lever 81 is urged in the direction of arrow F2 by its restoring force. ing. The cam roller 83 is rotatably attached to the lower end of a pin 85 fixed at a fixed position of the hinge arm 30. The pin 85 is connected to the upper surface portion 30A and the lower surface portion 30C of the hinge arm 30 as shown in FIG. It is spanned between.

  A cam surface 81 </ b> D that presses against the cam roller 83 is formed at the intermediate portion 81 </ b> C of the cam lever 81. The cam surface 81D in this example is formed long from the intermediate part 81C to the other end part 81B. The intermediate portion 81C of the cam lever 81 is located adjacent to the compression spring 82, and extends substantially along the compression direction of the compression spring 82, that is, the vertical direction in FIG. Further, the other end 81B of the cam lever 81 is positioned outside the compression spring 82, that is, above the compression spring 82 in FIGS. 9 and 10 when the door 2 is opened as shown in FIGS. To do.

  The second check mechanism 80 having such a configuration applies a predetermined check force to the relative rotation of the second hinge base 20 and the hinge arm 30 around the second shaft 32. As described above, the rotation range of the hinge arm 30 around the second shaft 32 corresponds to 80 degrees, that is, a range between 90 degrees and 170 degrees of the opening angle of the door 2. As the hinge arm 30 rotates, the cam roller 83 on the hinge arm 30 side moves as shown in FIG. 12 while rolling along the cam surface 81D of the cam lever 81.

  P11 in FIG. 12 is a moving position of the cam roller 83 when the rotation angle of the hinge arm 30 around the second shaft 32 is 0 degree as shown in FIGS. P12 in FIG. 12 is a moving position of the cam roller 83 when the rotation angle of the hinge arm 30 around the second shaft 32 is 80 degrees as shown in FIG. For such rotation of the hinge arm 30, a check force according to the shape of the cam surface 81 </ b> D in pressure contact with the cam roller 83 is applied. In the case of this example, a check force is applied so as to give a predetermined click feeling when the rotation angle of the hinge arm 30 is 0 degrees and 80 degrees.

  Such a second check mechanism 80 has a compression spring because the other end 81B of the cam lever 81 is located outside the compression spring 82, that is, on the exposed side when the door 2 is opened as shown in FIGS. The exposure degree of 82 can be suppressed small, and the favorable external appearance of a hinge apparatus can be maintained. Moreover, since the hinge arm 30 is also located outside the compression spring 82 when the door 2 is opened, the appearance of the hinge device can be better maintained. Further, since the intermediate portion 81C of the cam lever 81 is adjacent to the compression spring 82 and extends substantially along the compression direction of the compression spring 82, the cam lever 81 and the compression spring 82 can be efficiently deployed.

  Further, since the cam surface 81D of the cam lever 81 is formed on the side surface of the intermediate portion 81C located on the side opposite to the compression spring 82, the position of the cam roller 83 can be adjusted without particularly considering interference with the compression spring 82. The cam surface 81D can be set sufficiently large. By forming the cam surface 81D to be long, it is possible to finely set an optimal check force according to the opening angle of the door 2. In this example, since the formation range of the cam surface 81D extends to the position of the other end portion 81B, it can be formed longer.

  In addition, since the pin 85 is stretched between the upper surface portion 30A and the lower surface portion 30C of the hinge arm 30 and the cam roller 83 is attached to the pin 85, the cam roller 83 is firmly positioned and more accurate. Checking power can be given.

(Other embodiments)
The link mechanism 50 in the above-described embodiment is configured so that the first hinge starts from a time (second rotation time) during which the second hinge base 20 and the hinge arm 30 are allowed to rotate relative to each other while the door 2 is closed. The timing shifts to a time allowing the relative rotation of the base 10 and the hinge arm 30 (first rotation timing), and the driving force at the time of the shift is directly applied by the contact member 64 provided on the second hinge base 20. Given. On the other hand, during the opening of the door 2, the second hinge base 20 and the hinge arm 30 are moved from a time when the relative rotation of the first hinge base 10 and the hinge arm 30 is allowed (first rotation time). The timing shifts to a time permitting relative rotation (second rotation timing), and the starting force at the time of the shift is that the stepped portion 62C of the second cam 62 rotates the second control lever 52 in the direction of the arrow D1. It is given by the turning power when.

  However, the activation force at the time of the latter transition can be directly applied by the contact member without passing through the cam, similarly to the activation force at the time of the former transition. In that case, a contact member may be provided at a fixed position of the first hinge base 10 so that, at the time of the latter transition, the contact member abuts against the link mechanism 50 to give an activation force.

  In the above-described embodiment, the center of rotation of the hinge arm 30 is moved from the first shaft 31 to the second shaft 32 while the door 2 is opened, while the hinge arm 30 is moved while the door 2 is closed. The rotation center is configured to move from the second shaft 32 to the first shaft 31. However, on the contrary, the pivot center of the hinge arm 30 is moved from the second shaft 32 to the first shaft 31 while the door 2 is opened, while the hinge arm 30 is rotated while the door 2 is closed. The moving center can be configured to move from the first shaft 31 to the second shaft 32. In that case, what is necessary is just to make it the relationship which attaches the 1st hinge base 10 and the 2nd hinge base 20 with respect to the vehicle body 1 and the door 2 contrary to embodiment mentioned above.

  As described above, when the door 2 is opened and closed, the hinge arm 30 first rotates about the first shaft 31 and then rotates about the second shaft 32, or conversely, the door 2 The mode in which the hinge arm 30 first pivots about the second shaft 32 and then pivots about the first shaft 31 at the time of opening and closing is selected according to the usage mode of the door 2 and the like. be able to. For example, the hinge device of the former form can be used for doors that have many opportunities to open and close, and the hinge device of the latter form can be used for doors that frequently open and close. In particular, when the hinge device of the latter form is used, when the door is opened and closed small, the door rotates around the second shaft 32 on the side close to the door, so the first shaft 31 on the side far from the door is moved. The radius of rotation is smaller than when the door is pivoted about the center, and the door can be opened and closed by a small force.

  The hinge device of the present invention can be applied not only to a side door but also to a back door, etc. Further, the intermediate opening degree and the full opening degree of the door are not limited to the above-described embodiment and can be changed as appropriate. .
