Description

  The present invention relates to a vehicle interior device such as a vehicle cup holder device having a lid.

  Patent Document 1 uses a coil spring to apply an opening direction torque to a lid from a closed position to a predetermined position in the middle of opening and closing, in addition to a torsion spring that applies an opening direction torque to the entire lid. A technique for applying a closing direction torque to a lid by reversing tension and compression from a predetermined position to an open position is disclosed. Since the closing direction torque is applied to the lid body from the predetermined position to the open position using the coil spring, the lid body can be decelerated from the predetermined position to the open position.

The torque generated in the closing direction using the coil spring starts to be generated from a predetermined position (deceleration start position) during opening and closing, and gradually increases as the opening position is approached. Therefore, the opening speed of the lid body is decelerated at a constant deceleration rate, and the lid body is opened. For this reason, in the prior art, the lid speed characteristic as shown in the speed characteristic graph of FIG. 12 is shown, and it is difficult to express a rapid step-like speed change. It was difficult to produce a high-class feeling because it was unable to move at a substantially low speed.
Also, in order to prevent the lid from closing, the closing direction torque to the lid by the coil spring must be set weaker than the opening direction torque to the lid by the torsion spring, and torque adjustment is difficult. is there.

Japanese Patent No. 4615269

  An object of the present invention is to provide a vehicle interior device that can express at least one of a rapid step-like speed change and easy adjustment of torque to a lid by a spring.

The present invention for achieving the above object is as follows.
(1) a fixing member;
A lid that can be rotated and opened with respect to the fixing member;
A whole area spring for applying an opening direction torque to the fixing member to the lid in the entire area of opening and closing of the lid;
When the lid is between a closed position and a predetermined position in the middle of opening / closing, an opening direction torque is applied to the lid, and when the lid is between the predetermined position and the open position An initial speed spring that does not give torque to the fixing member to the lid;
A vehicular interior device.
(2) The initial speed spring includes a coil part, a first arm part connected to one axial end of the coil part, and a second arm part connected to the other axial end of the coil part. And
The first arm portion is in contact with the lid in the entire opening and closing region of the lid,
The second arm portion is in contact with the fixing member when the lid is between the closed position and the predetermined position, and when the lid is in the predetermined position, the fixing member and the lid The vehicle interior according to (1), wherein the vehicle interior is in contact with both the body and is in contact with only the lid away from the fixing member when the lid is between the predetermined position and the open position. apparatus.
(3) The vehicle interior device according to (2), wherein the second arm portion enters a rotation trajectory of the lid relative to the fixing member when the second arm portion is in contact with the fixing member.
(4) The opening direction torque for the fixing member generated in the lid body by the initial speed spring is larger than the opening direction torque for the fixing member generated in the lid body by the whole area spring. The vehicle interior device according to any one of to (3).

According to the vehicle interior device of the above (1), the entire area spring for applying the opening direction torque to the lid body in the entire opening and closing region of the lid body, and the lid body are between the closed position and a predetermined position in the middle of opening and closing. An opening direction torque is applied to the lid body, and an initial speed spring that does not apply torque to the lid body when the lid body is between the predetermined position and the open position. Therefore, until the lid reaches a predetermined position in the middle of opening and closing from the closed position, the opening direction torque of both the whole area spring and the initial speed spring is applied to the lid, and the lid reaches the open position beyond the predetermined position in the middle of opening and closing. Until, only the opening direction torque of the whole area spring is applied to the lid. As a result, the lid body can be decelerated stepwise at a predetermined position in the middle of opening and closing to express the speed change remarkably, and from the predetermined position in the middle of opening and closing to the open position, the speed is low and substantially constant. It can produce a luxury that opens.

  Further, since only the torque of the entire area spring is applied to the lid from a predetermined position during opening and closing to the open position, speed adjustment (torque adjustment) at a low speed from the predetermined position during opening and closing to the open position is easy.

  According to the vehicle interior device of the above (2), the initial speed spring has the coil portion and the first and second arm portions, and the first arm portion serves as the lid body in the entire region of opening and closing of the lid body. The second arm portion is in contact with the fixing member when the lid body is between the closed position and the predetermined position, and when the lid body is in the predetermined position, both the fixing member and the lid body are in contact with each other. When the lid is between the predetermined position and the open position, it is separated from the fixing member and is in contact with only the lid. Therefore, the opening direction torque can be applied to the lid body by the initial speed spring until the lid body reaches the predetermined position from the closed position, and the torque to the lid body by the initial speed spring (until the lid body reaches the open position beyond the predetermined position ( It is possible to eliminate not only the opening direction torque but also the closing direction torque.

According to the vehicle interior device of (3) above, the second arm portion of the initial speed spring enters the rotation trajectory of the lid when it is in contact with the fixing member. Therefore, after the lid body is rotated from the closed position to the open position and the lid body reaches a predetermined position, the second arm portion can be picked up by the lid body and the second arm portion can be separated from the fixing member. Therefore, the opening speed torque can be applied to the lid body by the initial speed spring until the lid body reaches the predetermined position from the closed position, and the torque to the lid body by the initial speed spring is applied until the lid body reaches the open position beyond the predetermined position. It can be lost.

  According to the vehicle interior device of the above (4), the opening direction torque generated in the lid body by the initial speed spring is set larger than the opening direction torque generated in the lid body by the whole area spring. Therefore, it is possible to increase the speed change amount of the lid at a predetermined position as compared with the case where the opening direction torque generated by the initial speed spring is smaller than the torque generated by the whole area spring on the lid. And can express a sharp step-like speed change when the lid opens.

The outer lid 32 is provided with a knob 32a that indicates a push target position when the lid 30 is pushed open.

  The lid first arm 33 and the lid second arm 34 are formed integrally with the lid inner 31. The lid first arm 33 is provided so as to extend from the one end of the lid inner 31 in the apparatus width direction to the fixing member 20 side, and the lid second arm 34 is the other end of the lid inner 31 in the apparatus width direction. To the fixing member 20 side. A damper 70 is attached to the lid first arm 33 or the lid second arm 34 in order to reduce the rotational speed of the lid 30 with respect to the fixing member 20 over the entire opening / closing region. FIG. 3 shows a case where the damper 70 is attached to the lid first arm 33. The damper 70 always meshes with an arcuate gear 71 provided on the fixed member 20.

  When the lid 30 is in the closed position 30a, the lid 30 is held in the closed position 30a by the lock device 60. The lock device 60 is, for example, a heart cam type lock device, and can be unlocked by pushing the lid 30 at the closed position 30a. When the locking device 60 is a heart cam type locking device, the locking device 60 includes a heart cam 61 provided on one of the fixing member 20 and the lid 30, and the fixing member 20 and the lid 30, as shown in FIG. 7. And a lock pin (not shown) that is provided on the other side and can be attached to and detached from the heart cam 61.

The whole area spring 40 is provided on one side in the width direction of the apparatus 10 (the extending direction of the axis P of the lid 30). For example, the lid of the lid first arm 33 and the lid second arm 34 is a lid. It is provided on the body first arm 33 side.

The entire area spring 40 applies an opening direction torque T <b> 1 to the fixing member 20 in the entire opening / closing region of the lid body 30. As shown in FIG. 2, the full-range spring 40 is formed of, for example, a torsion spring. The whole-area spring 40 includes a spring coil portion 41, a spring first arm 42 that is continuous with one axial end portion of the spring coil portion 41, and a spring second arm 43 that is continuous with the other axial end portion of the spring coil portion 41. .

  As shown in FIGS. 4 to 6, the spring first arm 42 is always in contact with the fixing member 20 (pressed, hooked, or engaged) in the entire opening / closing region of the lid 30. May be good). The spring second arm 43 is always in contact with the lid first arm 33 of the lid 30 (may be pressed, hooked, or engaged).

As shown in FIG. 2, the initial speed spring 50 is provided on the other side in the width direction of the device 10 (the extending direction of the axis P of the lid 30). For example, the first speed spring 50 and the lid 1 The second arm 34 is provided on the lid second arm 34 side. However, the initial speed spring 50 may be provided on one side in the width direction of the device 10.

When the cover 30 is between the closed position 30a and a predetermined position 30c in the middle of opening and closing, the initial speed spring 50 applies an opening direction torque T2 with respect to the fixing member 20 to the cover 30 and the cover 30 is moved to the predetermined position 30c. When it is between the open position 30b, no torque to the fixing member 20 is applied to the lid 30. The initial speed spring 50 does not apply not only the opening direction torque but also the closing direction torque to the lid body 30 when the lid body 30 is between the predetermined position 30c and the open position 30b.

The initial speed spring 50 is a torsion spring. The initial speed spring 50 includes a coil portion 51, a first arm portion 52 that is continuous with one axial end portion of the coil portion 51, and a second arm portion 53 that is continuous with the other axial end portion of the coil portion 51.

  As shown in FIGS. 8 to 10, the first arm portion 52 of the initial speed spring 50 is always in contact with the lid body 30 (pressed and hooked) in the entire opening / closing region of the lid body 30. Or may be engaged).

As shown in FIG. 8, (i) when the lid 30 is in the closed position 30a and the lid 30 is between the closed position 30a and the predetermined position 30c. (Ii) when the lid 30 is in the predetermined position 30c, as shown in FIG. 9, it is in contact with both the stationary member 10 and the lid 30 (iii) As shown in FIG. 10, when the lid 30 is between the predetermined position 30c and the open position 30b, and when the lid 30 is in the open position 30b, the lid 30 is separated from the fixing member 20 and contacts only the lid 30. ing. The “contact” of the second arm portion 53 of the initial speed spring 50 may be pressed, hooked, or engaged.

The second arm portion 53 of the initial speed spring 50 is in contact with both the fixing member 20 and the lid 30 when the lid 30 is in the predetermined position 30c, and the lid 30 is in the closed position 30a rather than the predetermined position 30c. When it is on the side, it is in contact only with the fixing member 20, and when the lid 30 is on the open position 30b side with respect to the predetermined position 30c, it is in contact with only the lid 30.

The fixed member 20 has a fixed member side contact portion 23 that is a portion that comes into contact with the second arm portion 53 and a lid body side contact portion 35 that has a portion that comes into contact with the second arm portion 53 of the cover body 30. In order to reduce the contact sound with the second arm portion 53, it is desirable that a sound hit prevention material made of a nonwoven fabric or the like is provided.

The second arm portion 53 of the initial speed spring 50 is in contact with the fixing member 20, that is, when the lid 30 is in the closed position 30a, and between the closed position 30a and the predetermined position 30c. When it exists in, it has entered in the rotation locus | trajectory with respect to the fixing member 20 of the cover body 30. FIG. Thereby, when the lid 30 rotates from the closed position 30a to the open position 30b, the second arm portion 53 can be picked up and separated from the fixing member 20 at the predetermined position 30c in the middle of opening and closing. .

The opening direction torque T2 with respect to the fixing member 20 generated in the lid body 30 by the initial speed spring 50 is larger than the opening direction torque T1 with respect to the fixing member 20 generated in the lid body 30 by the whole area spring 40. However, T2 may be the same as T1, or may be smaller than T1.

Here, the operation of the lid 30 will be described.
(A) When the lid 30 is in the closed position 30a, the second arm portion 53 of the initial speed spring 50 is in contact with the fixed member side contact portion 23 as shown in FIG. Therefore, not only the opening direction torque T <b> 1 due to the whole area spring 40 but also the opening direction torque T <b> 2 due to the initial speed spring 50 is applied to the lid 30.

(B) When the lock of the lock device 60 is released and the cover 30 is turned to the open position 30b side, the lock device 60 is unlocked. The lid 30 is rotated in the opening direction by both the directional torques T2.
(B1) When the lid 30 reaches the predetermined position 30c, as shown in FIG. 9, the lid-side contact portion 35 hits the second arm portion 53 of the initial speed spring 50, and the second arm portion 53 is on the lid side. Picked up by the contact portion 35.
(B1) When the lid 30 exceeds the predetermined position 30c, the second arm portion 53 is separated from the fixed member side abutting portion 23 and contacts only the lid side abutting portion 35. Thereby, both arm parts 52 and 53 of the initial speed spring 50 are caught by the cover body 30, and the torque to the cover body 30 by the initial speed spring 50 is lost. As a result, until the lid 30 reaches the open position 30b, only the opening direction torque T1 by the whole area spring 40 is applied to the lid 30.

(C) When the lid 30 is in the open position 30b, as shown in FIG. 10, the second arm portion 53 of the initial speed spring 50 is in contact with the lid-side contact portion 35 and is in contact with the fixing member 20. Not done. Therefore, the torque by the initial speed spring 50 is not applied to the lid 30, but only the opening direction torque T <b> 1 by the whole area spring 40 is applied. The open state of the lid 30 is maintained by a stopper (not shown) coming into contact with the fixing member 20.

(D) When the lid body 30 at the open position 30b is rotated to the closed position 30a side, the lid body 30 is manually turned against the opening direction torque T1 by the whole-area spring 40 from the lid body 30 open state shown in FIG. Is rotated toward the closed position 30a.
(D1) When the lid body 30 reaches the predetermined position 30c, as shown in FIG. 9, the second arm portion 53 of the initial speed spring 50 hits the fixed member side contact portion 23.
(D2) When the lid 30 is further rotated toward the closed position 30a, the second arm portion 53 is separated from the lid-side contact portion 35 and contacts only the fixed member-side contact portion 23. Thereby, the opening direction torque T2 to the cover body 30 by the initial speed spring 50 is generated. As a result, both the opening direction torque T1 due to the whole area spring 40 and the opening direction torque T2 due to the initial speed spring 50 are applied to the lid body 30 until the lid body 30 exceeds the predetermined position 30c and reaches the closed position 30a. The lid 30 is rotated by hand to the closed position 30a against the sum of the torques T1 and T2.

Next, effects of the embodiment of the present invention will be described.
When the lid 30 is between the closed position 30a and a predetermined position 30c in the middle of opening and closing, the lid 30 is opened when the whole area spring 40 for applying the opening direction torque T1 to the lid 30 in the entire opening and closing region of the lid 30 is present. An initial speed spring 50 that applies directional torque T2 and does not apply torque to the lid 30 when the lid 30 is between the predetermined position 30c and the open position 30b. Therefore, until the lid 30 reaches the predetermined position 30c in the middle of opening and closing from the closed position 30a, the opening direction torques (T1 + T2) of both the whole area spring 40 and the initial speed spring 50 are applied to the lid 30 and the lid 30 is in the middle of opening and closing. Until the predetermined position 30c is reached and the open position 30b is reached, only the opening direction torque T1 of the whole area spring 40 is applied to the lid 30. As a result, as shown in FIG. 11, the lid 30 can be suddenly decelerated in a step shape at a predetermined position 30c in the middle of opening and closing to express the speed change remarkably, and from the predetermined position 30c in the middle of opening and closing. Up to the open position 30b, it is possible to produce a high-class feeling that opens at a substantially low speed at a low speed.

  Further, since only the torque T1 of the entire area spring 40 is applied to the lid body 30 from the predetermined position 30c in the middle of opening and closing to the open position 30b, it is only necessary to adjust the torque of a single spring. Speed adjustment at low speeds up to 30b is easy.

  The initial speed spring 50 has a coil portion 51 and first and second arm portions 52 and 53, and the first arm portion 52 is in contact with the lid body 30 in all areas of opening and closing of the lid body 30, The second arm portion 53 is in contact with the fixing member 20 when the lid 30 is between the closed position 30a and the predetermined position 30c, and the fixing member 20 and the lid when the lid 30 is at the predetermined position 30c. 30 and is in contact with only the lid 30 away from the fixing member 20 when the lid 30 is between the predetermined position 30c and the open position 30b. Therefore, the opening direction torque T2 can be applied to the lid body 30 by the initial speed spring 50 until the lid body 30 reaches the predetermined position 30c from the closed position 30a, and until the lid body 30 exceeds the predetermined position 30c and reaches the open position 30b. Torque to the lid 30 by the initial speed spring 50 can be eliminated.

  When the second arm portion 53 of the initial speed spring 50 is in contact with the fixing member 20, the second arm portion 53 enters the rotation locus of the lid 30. Therefore, after the lid body 30 rotates from the closed position 30a to the open position 30b and the lid body 30 reaches the predetermined position 30c, the lid body 30 picks up the second arm portion 53 and moves the second arm portion 53 to the second position. The fixing member 20 can be separated. Therefore, the opening direction torque T2 can be applied to the lid body 30 by the initial speed spring 50 until the lid body 30 reaches the predetermined position 30c from the closed position 30a, and until the lid body 30 reaches the open position 30b beyond the predetermined position 30c. Torque to the lid 30 by the initial speed spring 50 can be eliminated.

The opening direction torque T2 generated in the lid body 30 by the initial speed spring 50 is larger than the opening direction torque T1 generated in the lid body 30 by the whole area spring 40 (T2> T1). Therefore, the opening direction torque T2 generated in the lid body 30 by the initial speed spring 50 is smaller than the torque T1 generated in the lid body 30 by the whole area spring 40 (T2 <T1). The speed change amount (D in FIG. 11) of the lid body 30 can be increased, and a rapid step-like speed change when the lid body 30 is opened can be remarkably expressed.
