Therefore, it is possible to change the arm from the use state to the housed state simply by moving the gravity center adjusting member 50.
- the arm of the parallel link is an I-shape instead of an L-shape, but it goes without saying that the same effect as described above can be obtained even with an L-shape arm. .
- FIG. 13 for convenience of illustration, only one parallel link is shown. However, as described above, the center-of-gravity adjusting member 50 is provided on each of the first parallel link 20 and the second parallel link. It is.
- the center-of-gravity adjusting member 50 is attached so that x1 and x2 are equal when the parallel link is horizontal. Let x1 and x2 at this time be A.
- the center-of-gravity adjusting member may be designed so that Equation 5 can be satisfied.
- the center-of-gravity adjustment member 50 is configured by housing a liquid 52 in a case 51 as shown in FIG. 15A. Thereby, when the arm is tilted, the center of gravity of the center of gravity adjusting member moves. When it is desired to increase the center of gravity movement amount of the center of gravity adjusting member 50, the case 51 is lengthened in the left-right direction in FIG. Variations such as are possible. By doing so, more liquid flows in the direction in which the arm is inclined.
- the center-of-gravity adjusting member 50 may be attached to the lower arm of the first parallel link 10 and the second parallel link 20 as shown in FIG. 12, or the upper side as shown in FIGS. It may be attached to the other arm. When attached to the lower arm, the load acting on the upper arm can be reduced, and the upper arm can be made thinner and lighter.
- the support arm according to the present modification is characterized in that a storage assist mechanism 60 for assisting the storage operation of the support arm is provided.
- the storage assisting mechanism 60 includes a weight member 62 connected to the tip member 40B, a first placement portion 11 and a second placement portion 12 that are provided on the base 10 and on which the weight member 62 can be placed. And a container 61 as a “third placement portion” provided on the two parallel links 20 on which the weight member 62 can be placed.
- FIG. 16 shows the storage state of the support arm according to this modification. In this state, the weight member 62 is placed on the first placement unit 11.
- FIG. 17 is a diagram showing a state where the support arm is shifted from the stored state to the used state. As shown in FIG. 17, by moving the weight member 62 from the first placement unit 11 to the container 61, as shown in FIG. 18, the first parallel link 10 and the second parallel link 20 become horizontal. This state is the use state of the support arm.
- the weight member 62 is moved from the container 61 to the second placement unit 12. As a result, the tip member 40B and the charging connector 100C are lifted upward. Here, the fulcrum of the first parallel link 10 on the base 10 side is locked. Thereafter, the weight member 62 is moved to the first placement portion, whereby the state shown in FIG. 16 (support arm storage state) is restored.
- the support arm can be returned from the use state to the housed state by a simple operation of replacing the weight member 62. Therefore, the support arm is in the use state after the use of the charging connector 100C. It can be suppressed from being left as it is.
- the present invention can be applied to a support arm that supports a charging connector of a hybrid vehicle or the like.

Abstract
Description
次に、図8A~図11を用いて、本実施の形態に係るサポートアームの第1変形例について説明する。
次に、図12~図15を用いて、本実施の形態に係るサポートアームの第2変形例について説明する。図12に示すように、本変形例に係るサポートアームは、第1平行リンク20および第2平行リンク30に、各々、重心調整部材50を設けたことを特徴としている。重心調整部材50は、筐体内に液体が収納された構造を有している。
なお、重心調整部材50は、図15Aに示すように、ケース51内に液体52を収納したもので構成される。これにより、アームが傾いたときに重心調整部材の重心が移動する。なお、重心調整部材50の重心移動量を大きくしたい場合は、ケース51を図15Aの左右方向に長くする、または、図15Bに示すように、ケース51の中心位置においてケース51の底を高くするなどの変形が考えられる。このようにすることで、より多くの液体がアームの傾いた方向に流れることになる。
次に、図16~図19を用いて、本実施の形態に係るサポートアームの第3変形例について説明する。図16~図19に示すように、本変形例に係るサポートアームは、該サポートアームの収納作業を補助する収納補助機構60を設けた点を特徴とする。
