Definitions
- FIG. 16 shows the conventional hinge device 1 described in Patent Documents 1 and 2, and discloses a torque variable structure capable of a free stop operation.
- FIG. 16 shows a state where the second member 120 is closed with respect to the first member 110 at an angle of 0 °.
- the hinge device 1 includes a shaft member 2 fixed to the second member 120 with the screw 7 and a bracket 3 fixed to the first member 110 with the screw 8, and the cam member 5 is fixed to the shaft member 2. .
- the bracket 3 is formed by a flat flange portion 31 on the bottom surface side and a bearing portion 32 rising upright from the flange portion 31, and the flange portion 31 is screwed to the first member 110. Fixed by. Therefore, the bracket 3 is a fixed side member. In the fixed state of the bracket 3, the bearing portion 32 is raised from the first member 110. A circular shaft hole 33 is formed in the bearing portion 32, and the shaft body 22 of the shaft member 2 passes through the shaft hole 33 in a rotatable manner.
- the recess 12 is formed by a low surface portion 12a that is lowered, a high surface portion 12b that is high, and a slope portion 12c that connects them.
- the low surface portion 12a, the slope portion 12c, and the high surface portion 12b are formed so as to be continuous along the clockwise direction around the shaft hole 33.
- FIG. 20 shows the friction torque T that changes depending on the opening angle ⁇ of the second member 120.
- the relationship between the friction torque T (N / mm) and the deflection ⁇ (mm) of the leaf spring 61 when using three leaf springs 61 having the same spring constant as the biasing means 6 is as follows. As shown in FIG. Here, the height difference of the recess 12 is set to 0.4 mm.
- the height difference of the recess 12 can be increased to reduce the spring constant of the leaf spring 61.
- a spring with a small deflection amount is used. Many need to be stacked. This causes a problem that the hinge device 1 becomes longer in the axial direction.
- the urging means is a spring whose spring constant changes as the friction torque changes.
- the biasing means since the biasing means has the inflection point of the spring constant between the maximum value and the minimum value of the friction torque generated between the cam member and the bracket, the friction is caused by the rotation of the second member. The torque changes, and the cam member and the bracket are biased in response to the change. For this reason, the friction torque can be changed with high accuracy.
- the urging means contacts the bracket and generates a friction torque.
- the urging means has an inflection point of a spring constant between the maximum value and the minimum value of the friction torque. Therefore, even if the friction torque changes due to the rotation of the second member, the biasing means biases the bracket in response to this change. For this reason, the friction torque can be changed with high accuracy.
- the shaft member 2, the friction member 9, the cam member 5, and the stopper plate 10 are the same as the hinge device 1 shown in FIG. That is, the shaft member 2 is formed by the shaft body 21 and the shaft body 22 having a non-circular outer shape integrally extending from one side surface of the shaft body 21. As in FIG. 16, the shaft member 2 is fixed to the second member 120 with the screw 7 and rotates together with the second member 120.
- the cam member 5 has a circular outer shape, and a non-circular shaft hole 53 corresponding to the shaft body 22 of the shaft member 2 is formed, and the shaft body 22 penetrates the shaft hole 53.
- the cam member 5 rotates integrally with the rotation of the shaft member 2, slides with respect to the bracket 3 by this rotation, and generates a friction torque with the bracket 3.
- An arc-shaped convex portion 11 is formed on the friction surface 54 of the cam member 5 as in FIG. The convex portion 11 extends linearly from side to side with the shaft hole 53 sandwiched between the shaft hole 53 and the center.
- the first spring 41 constituting the biasing means 4 has a small plate thickness and a small spring constant as shown in FIG. 3, and can be bent greatly.
- the second spring 42 has a large plate thickness and a large spring constant, and is a high load and low deflection spring.
- Such two springs 41 and 42 have different spring constants, and the biasing means 4 is formed by overlapping two springs 41 and 42 having different spring constants.
- FIG. 6 is a characteristic diagram showing the relationship between the deflection ⁇ of the springs 41 and 42 of the biasing means 4 and the friction torque T in this embodiment, and in this embodiment, it changes along the E3 line shown by a solid line.
- the torque T1 is 100N.
- the first spring 41 is bent to a state immediately before contact with the cam member 5.
- the biasing means 4 comprising the first spring 41 and the second spring 42 has an inflection point where the first spring 42 switches to the second spring 42 between the maximum value T2 and the minimum value T1. Yes. Therefore, even if the friction torque changes due to the rotation of the second member 120, the biasing means 4 biases the cam member 5 and the bracket 3 in response to this change. For this reason, the friction torque can be changed with high accuracy.
- the convex portion 11 may be formed on the bracket 3 and the concave portion 12 may be formed on the cam member 5. Moreover, it is possible to change the angle setting of the recessed part 12 suitably.
