The base plate 10 is erected.

  As shown in FIG. 2, in the present embodiment, a back fixing plate 52 is provided as the second fixing support portion 20b. The back fixing plate 52 is fixed on the base plate 10 so as to be positioned in the vicinity of the back end of the base plate 10. The back fixing plate 52 is located behind the battery pack 800. The back fixing plate 52 and the base plate 10 are coupled to each other by a screw 19 that is screwed into the back fixing plate 52 via the base plate 10 from below the base plate 10.

  The left support portion 30 includes a pad (an example of a side support member) 31, a shaft 33, a spring (an example of an elastic member) 34, and a knob 37.

  The pad 31 is arranged so that the pad surface 31 a formed on one surface thereof faces the left side surface 803 of the battery pack 800. In other words, the pad 31 is disposed in a state facing the right support portion 40 so that the pad surface 31a hits the battery pack 800 when the holding device 1 is used. The pad surface 31 a has a shape with projections and depressions toward the battery pack 800. In the present embodiment, a tapered portion 31z is formed on the pad surface 31a so that the distance between the pad 31 and the pad 41 of the right support portion 40 increases as it approaches the upper end. .

  The shaft 33 is inserted into the hole 31b provided in the pad 31 from the pad surface 31a side, passes through the pad 31, and is screwed into a screw hole 35b provided in the side fixing plate 35. Thereby, the pad 31 is supported by the side fixing plate 35 via the shaft 33.

  The spring 34 is a coil spring. The spring 34 is arranged substantially coaxially with the shaft 33, that is, so that the shaft 33 penetrates the inside of the spring 34.

  The spring 34 is disposed in a compressed state between the left side surface of the pad 31 (the surface opposite to the pad surface 31 a) and the right side surface of the side fixing plate 35. Therefore, the pad 31 is urged by the spring 34 in the right direction (Y direction in FIG. 2) with respect to the side fixing plate 35 and the base plate 10. The pad 31 is held in a state where a position that can be taken with respect to the shaft 33 is regulated by contacting the flange portion 33 a of the shaft 33.

  Even when the pad 31 is urged by the spring 34, the pad 31 can be displaced in the axial direction (left direction) of the shaft 33 by compressing the spring 34. When the pad 31 is urged by the spring 34, the collar portion 33a enters the pad 31, and the collar portion 33a does not protrude from the pad surface 31a.

  Here, the amount of protrusion of the shaft 33 from the side fixing plate 35 in the right direction can be changed by rotating the shaft 37 with respect to the side fixing plate 35 by rotating the knob 37 or the like. is there. At this time, the position of the pad 31 with respect to the shaft 33 is maintained by the biasing force of the spring 34. Therefore, when the shaft 33 rotates, the position of the pad 31 with respect to the side fixing plate 35 changes. That is, the pad 31 is provided so that the position with respect to the side fixing plate 35 can be adjusted in a direction (Y direction in FIG. 2) in a direction far from the pad 41 of the right support portion 40 described later.

That is, the pad 41 is disposed in a state facing the left support portion 30 so that the pad surface 41a hits the battery pack 800 when the holding device 1 is used. The pad 41 is disposed so as to face the pad 31. In the present embodiment, a tapered portion 41z is formed on the upper surface of the pad surface 41a so as to increase the distance between the pads 31 and 41 as it approaches the upper end. The pad 41 has a substantially symmetric shape with the pad 31 except for a portion to which the shafts 43a and 43b are attached.

  The shaft 43 a is attached above the pad 41. The shaft 43b is attached below the pad 41 and below the shaft 43a. Fixing screws 46a and 46b are screwed into the shafts 43a and 43b so as to penetrate the pad 41 from the pad surface 41a side. Thereby, the shafts 43 a and 43 b are fixed to the pad 41.

The shafts 43a and 43b are slidable in the axial direction (Y direction in FIG. 2) with respect to the side fixing plate 45. Thereby, the pad 41 is slidably supported by the side fixing plate 35 via the two shafts 43a and 43b. That is, the pad 41 is provided so as to be displaceable with respect to the side fixing plate 45 and the base plate 10 in a direction in which the pad 41 of the left support portion 30 is far from or closer to.

  Stopper members 47a and 47b are attached to the ends of the shafts 43a and 43b, respectively. The stopper members 47a and 47b are, for example, screws having washers whose radial dimension is larger than the inner diameter of the hole 45a of the side fixing plate 45. The stopper members 47 a and 47 b restrict the range in which the shafts 43 a and 43 b and the pad 41 can slide with respect to the side fixing plate 45. In the present embodiment, for example, the pad 41 is located on the left support part 30 side beyond the center part (position where an electrode 71 described later) is disposed where the pad surface 41a is disposed in the top view. It is regulated by the stopper members 47a and 47b so as not to overhang.

  The springs 44a and 44b are coil springs. The springs 44a and 44b are disposed substantially coaxially with the shafts 43a and 43b. The springs 44a and 44b are arranged such that the shafts 43a and 43b penetrate the springs 44a and 44b.

  The springs 44 a and 44 b are arranged in a compressed state between the right side surface of the pad 41 (surface opposite to the pad surface 41 a) and the left side surface of the side fixing plate 45. That is, the pad 41 is urged by the springs 44 a and 44 b in the left direction, that is, toward the left support portion 30 with respect to the side fixing plate 45 and the base plate 10.

  Even in the state of being biased by the springs 44a and 44b, the pad 41 can be displaced in the axial direction of the shafts 43a and 43b so as to compress the springs 44a and 44b. In the present embodiment, the restoring force of the two springs 44 a and 44 b acting on the pad 41 when the holding device 1 is in use is slightly smaller than the restoring force of the spring 34 acting on the pad 31. Thus, when the battery pack 800 is held by the holding device 1 as described later, the user can easily displace the pad 41 and place the battery pack 800 at a predetermined position.

  The biasing force (restoring force) by the springs 44a and 44b is, for example, so that the battery pack 800 is reliably held between the pad 41 and the pad 31 when the battery pack 800 is set on the holding device 1. Is set. The biasing force may be set by adjusting, for example, the spring constant or the natural length of the spring.

  The side fixing plate 35 and the side fixing plate 45 are common members having the same shape. That is, each of the side fixing plates 35 and 45 is provided with a screw hole 35b and two hole portions 45a. In this way, by sharing parts, the manufacturing cost of the holding device 1 is reduced. Moreover, the holding device 1 can be easily assembled by reducing the kind of components.

However, when the holding device 1 is assembled, the pad 51 comes into contact with the pads 31 and 41 and the side fixing plates 35 and 45 before the shafts 53a and 53b are removed from the pad 51. Never do. Thus, since it is comprised so that it is not necessary to provide the member for regulating the position of the pad 51, the number of parts of the holding fixture 1 can be decreased, manufacturing cost can be reduced, and assembly can be facilitated. Can do.

  In a state where the pad 51 is held by the shafts 53a and 53b, the springs 54a and 54b are formed on the back surface of the pad 51 (the surface opposite to the surface on which the recess 51c is provided) and the front surface of the back fixing plate 52. It is in the state compressed between. That is, the pad 51 is urged forward by the springs 54a and 54b with respect to the back fixed plate 52 and the base plate 10, that is, toward the fixed support portion 20a.

  [Description of Holding Device 1 with Battery Pack 800 Set]

  FIG. 8 is a perspective view showing the holding device 1 in a state where the battery pack 800 is set. FIG. 9 is a plan view of the holding device 1 in a state where the battery pack 800 is set. FIG. 10 is a side view of the holding device 1 in a state where the battery pack 800 is set.

  Next, the holding device 1 in a state where the battery pack 800 is set will be described with reference to FIGS.

  As shown in FIG. 8, the battery pack 800 is sandwiched between the front fixing plate 21 and the pad 51 of the back support part 50, and between the pad 31 of the left support part 30 and the pad 41 of the right support part 40. And is held by the holding device 1. The battery pack 800 is supported by the support plate 61 and is held by the holding device 1. The pad 51 is biased toward the front fixing plate 21, and the pad 41 is biased toward the pad 31. Further, the pad 31 is biased toward the pad 41. As described above, the pads 31, 41, 51 are biased by the springs 34, 44a, 44b, 54a, 54b, so that the battery pack 800 is reliably maintained in the state of being held by the holding device 1. The

  The battery pack 800 is held by the holding device 1 with the front surface 802 positioned on the front fixing plate 21, the left side surface 803 positioned by the pad 31 of the left support portion 30, and the bottom surface 806 positioned by the support plate 61. ing. At this time, the battery pack 800 is positioned so that the terminal 810 on the front surface 802 contacts the electrode 71. Thereby, the state where the electrode 71 is in contact with the terminal 810 is reliably maintained.

For example, when the first battery pack 800 is set, instead of the first battery pack 800, when the second battery pack 800 having a thickness 10 mm thicker than that is set, the thickness of both battery packs 800 is set. The position of the pad 31 can be adjusted by a dimension that is half the difference (ie, 5 mm). As a result, the second battery pack 800 can be easily set so as to be aligned with the center position of the first battery pack 800.

  Thus, the user can hold the battery pack 800 by the holding device 1 with an easy operation. In addition, the electrode 71 that needs to be connected to the terminal 810 in order to perform the test of the battery pack 800 can be connected to the terminal 810 at the same time that the battery pack 800 is held by the holding device 1. At this time, the electrode 71 can be reliably maintained in contact with the terminal 810 by keeping the battery pack 800 held by the holding device 1.

  Each pad 31, 41, 51 can be displaced in a predetermined direction while compressing the springs 34, 44 a, 44 b, 54 a, 54 b even when the battery pack 800 is held. Therefore, for example, even if the held battery pack 800 is deformed (for example, expanded), the holding device 1 allows the battery pack 800 to be deformed without applying a large stress to the battery pack 800, and the battery pack. 800 can continue to be held. Therefore, battery pack 800 can be safely held.

Yes. Therefore, each member can be easily molded. Further, even if an abnormality occurs in the battery pack 800 held by the holding device 1, insulation between the members outside the holding device 1 and the battery pack 800 can be maintained, and a safe state is maintained.

  FIG. 11 is a front view showing the pads 31 and 41 of the holding device 1.

  In the present embodiment, the taper portions 31z and 41z are formed on the upper portions of the pads 31 and 41, so that the operation of holding the battery pack 800 by the holding device 1 can be performed more easily. . That is, as shown in FIG. 11, when the battery pack 800 is not held by the holding device 1, the pad 41 is close to the pad 31, and the tapered portion 31z and the tapered portion 41z face each other. In this state, when the user presses the bottom portion of the battery pack 800 against the taper portions 31z and 41z and applies a downward force to the battery pack 800, the force is applied in the direction of widening the gap between the pad 31 and the pad 41. work. Thereby, the space | interval of the pad 31 and the pad 41 spreads, and the battery pack 800 can be arrange | positioned between both the pads 31 and 41. FIG. Even if the operation of directly displacing the pads 31 and 41 is not performed, the interval between the pads 31 and 41 can be easily changed and the battery pack 800 can be set.
