[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2007-150110 Summary of the Invention [Problem to be solved by the invention]

[0004] The inventors have found the following problems. If a wire is provided between the door and the housing to electrically connect the door and the housing body, there is a risk that the wire will become pinched between the door and the housing body and break when the door is opened or closed.

[0005] The present disclosure has been made in consideration of such circumstances, and provides a battery housing that allows the door to be grounded while preventing the wire from breaking, even when a wire is provided between the door and the housing body. [Means for solving the problem]

[0006] The battery housing according to the present disclosure comprises: a housing body that houses a battery; a door for inserting and removing a battery from the housing body; A battery housing comprising: a link mechanism provided between the housing body and the door, in which a plurality of links are joined; one end of the link mechanism is fixed to the door and the other end of the link mechanism is fixed to the housing main body so that the door can be opened and closed via the link mechanism; At each joint, the links are electrically connected by a first metal wire, One end of the link mechanism and the door are electrically connected by a second metal wire; The other end of the link mechanism and the housing body were electrically connected by a third metal wire.

[0007] In the battery housing according to the present disclosure, a link mechanism is provided between the housing body and the door, and wires are provided at the fastening point between one end of the link mechanism and the door, at the fastening point between the other end of the link mechanism and the housing body, and near the joint. This configuration can prevent the second wire from being pinched in the fastening point between one end of the link mechanism and the door. It can also prevent the third wire from being pinched in the fastening point between the other end of the link mechanism and the housing body. It can also prevent the first wire from being pinched in the joint. Therefore, even if a wire is provided between the door and the housing body, the door can be grounded while preventing the wire from breaking.

[0008] The door may further include a first guide portion provided between the first wire and the joint so that the first wire provided for each joint can be spaced a predetermined distance from the joint. By configuring in this way, it is possible to more reliably prevent the first wire from being caught in the joint when opening or closing the door.

[0009] Furthermore, the device may include a second guide portion provided between the second wire and a fixed portion between one end of the link mechanism and the door so that the second wire can be spaced a predetermined distance from a fixed portion between one end of the link mechanism and the door, and a third guide portion provided between the third wire and a fixed portion between the other end of the link mechanism and the housing body so that the third wire can be spaced a predetermined distance from a fixed portion between the other end of the link mechanism and the housing body. With this configuration, it is possible to more reliably prevent the second wire from being caught in the fixed portion between the one end of the link mechanism and the door, or the third wire from being caught in the fixed portion between the other end of the link mechanism and the housing body when opening or closing the door. [Effects of the Invention]

[0010] The present disclosure makes it possible to provide a battery housing that can ground the door while preventing the wire from breaking even when a wire is provided between the door and the housing body. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0012] The present disclosure will be described below through embodiments of the invention, but the invention according to the claims is not limited to the following embodiments. Furthermore, not all of the configurations described in the embodiments are necessarily essential means for solving the problems. For clarity of explanation, the following description and drawings have been omitted and simplified as appropriate. In each drawing, the same elements are given the same reference numerals, and repeated explanations are omitted as necessary.

[0013] Naturally, the right-handed xyz Cartesian coordinate system shown in the drawings is for the convenience of explaining the positional relationships of the components. Normally, the positive direction of the z axis is vertically upward, and the xy plane is the horizontal plane.

[0014] (Embodiment 1) <Battery housing> First, the configuration of the battery casing according to the first embodiment will be described with reference to Figs. 1 and 2. Fig. 1 is an xy plan view of the battery container according to the first embodiment. Fig. 2 is a perspective view of the battery container according to the first embodiment. Fig. 1 shows the state in which the door is open from the left to the right. Note that in Fig. 1, the first guide portion 30, the second guide portion 31, and the third guide portion 32 are shown in the right view, but the first guide portion 30, the second guide portion 31, and the third guide portion 32 are omitted in the left view and the center view.

[0015] As shown in Figures 1 and 2, the battery housing 100 includes a door 10, a housing body 11, and a link mechanism 20. The door 10 and the housing body 11 will now be described. The housing body 11 houses a battery (not shown in Figures 1 and 2). In the battery housing 100, when the door 10 is in an open state, the battery (not shown in Figures 1 and 2) can be inserted or removed from the housing body 11. In the battery housing 100, when the battery (not shown in Figures 1 and 2) is inserted or removed from the housing body 11, the door 10 is closed. The door 10 is attached to a hinge 60 provided on the housing body 11 so that it can be opened and closed.

[0016] The link mechanism 20 will now be described. As shown in Fig. 1, the link mechanism 20 is provided between the door 10 and the housing main body 11. As shown in Fig. 1, the link mechanism 20 includes a link 21 and a link 22. The link mechanism 20 shown in Fig. 1 includes a joint 40, at which the link 21 and the link 22 are joined.

[0017] 1 and 2, one end (link 22 side) of the link mechanism 20 is fixed to the door 10 at a fixing point 41. As shown in FIGS. 1 and 2, the other end (link 21 side) of the link mechanism 20 is fixed to the housing main body 11 at a fixing point 42.

[0018] 1 and 2, one end of the link mechanism 20 (the link 22 side) is fixed to the door 10 at a fixing point 41, and the other end of the link mechanism 20 (the link 21 side) is fixed to the housing main body 11 at a fixing point 42. The links 21 and 22 are joined at a joint 40. With this configuration, the door 10 in the battery housing 100 can be opened and closed via the link mechanism 20. The first guide portion 30, the second guide portion 31, and the third guide portion 32 shown in FIG. 1 will be described later.

[0019] <Earth> Next, the grounding of the door 10 will be described with reference to Figures 1 and 2. In the battery housing 100, regulations regarding electrical equipment require that the door 10 be grounded. As shown in Figure 1, in the link mechanism 20, a first wire 70 is provided near the joint 40. The first wire 70 electrically connects the link 21 and the link 22.

[0020] 1, a second wire 80 is provided near the fixing point 41. The second wire 80 electrically connects one end of the link mechanism 20 (the link 22 side) and the door 10.

[0021] 1, a third wire 90 is provided near the fixed point 42. The third wire 90 electrically connects the other end (the link 21 side) of the link mechanism 20 to the housing main body 11. The first wire 70, the second wire 80, and the third wire 90 are metal wires and are electrically conductive.

[0022] In other words, in the battery casing 100, the second wire 80 electrically connects the door 10 and the link 22, the first wire 70 electrically connects the link 22 and the link 21, and the third wire 90 electrically connects the link 21 and the casing body 11. Also, as shown in Fig. 2, in the battery casing 100, the casing body 11 is in contact with the ground Gr. With this configuration, the door 10 in the battery casing 100 is electrically connected to the ground Gr and is grounded by the wires rather than by conductive grease.

[0023] In the past, battery housings were grounded by fixing one end of a wire to the door and the other end to the housing body, but with this configuration, there was a risk that the wire would get caught between the door and the housing body and break when the door was opened or closed.

[0024] 1 and 2, a link mechanism 20 is provided between the housing body 11 and the door 10, and wires are provided near the fixing points 41, 42 and the joint 40. In other words, the housing body 11 and the door 10 are electrically connected by three wires.

[0025] This configuration can prevent the second wire 80 from being pinched at the fixing point 41. It can also prevent the third wire 90 from being pinched at the fixing point 42. It can also prevent the first wire 70 from being pinched in the joint 40. Therefore, in the battery housing 100, even if a wire is provided between the door 10 and the housing body 11, it is possible to ground the door while preventing the wire from breaking.

[0026] 1 and 2, the link mechanism 20 has been described as having one joint 40. However, this is not limited thereto, and the link mechanism 20 may have a plurality of joints, with adjacent links being joined together. When the link mechanism 20 has a plurality of joints, a first wire is provided for each joint so as to electrically connect the links joined by that joint.

[0027] In addition, the first wire 70, second wire 80 and third wire 90 shall be wires of 2.5 mm or more for Type A installation work, 5.5 mm or more for Type B installation work, and 1.6 mm or more for Type C and Type D installation work.

[0028] <Guide> The guide portion will be described with reference to Fig. 3. Fig. 3 is a perspective view showing the joints of the link mechanism. Note that Fig. 3 shows an example in which one link 22 is joined to two links 21, but the link mechanism may also have one link 22 joined to one link 21.

[0029] As shown in Fig. 3, the first guide portion 30 is provided near the joint 40 between the link 21 and the link 22. More specifically, the first guide portion 30 is provided between the first wire 70 and the joint 40. In the example shown in Fig. 3, the first guide portion 30 is provided at the joint 40 so as to extend from the link 21, but this is not limitative, and the first guide portion 30 may also be provided at the joint 40 so as to extend from the link 22.

[0030] The first guide part 30 allows the first wire 70 to be spaced a predetermined distance from the joint 40. This more reliably prevents the first wire 70 from being caught in the joint 40 when opening or closing the door 10 (see FIGS. 1 and 2).

[0031] Furthermore, as shown in the right diagram of FIG. 1, the battery casing 100 may include a second guide portion 31 and a third guide portion 32. As shown in FIG. 1, the second guide portion 31 is provided near the fixing point 41. More specifically, as shown in FIG. 1, the second guide portion 31 is provided between the second wire 80 and the fixing point 41. As shown in FIG. 1, the third guide portion 32 is provided near the fixing point 42. More specifically, as shown in FIG. 1, the third guide portion 32 is provided between the third wire 90 and the fixing point 42.

[0032] The second wire 80 can be separated a predetermined distance from the fixed point 41 by the second guide portion 31. Furthermore, the third wire can be separated a predetermined distance from the fixed point 42 by the third guide portion 32. This more reliably prevents the second wire 80 from being pinched in the fixed point 41 and the third wire 90 from being pinched in the fixed point 42 when opening or closing the door 10 (see FIGS. 1 and 2). Therefore, in the battery housing 100, even if a wire is provided between the door 10 and the housing body 11, the door can be grounded while preventing the wire from breaking.

[0033] The battery casing 100 may not necessarily include the first guide portion 30, the second guide portion 31, and the third guide portion 32 described above.

[0034] The present disclosure is not limited to the above-described embodiments, and can be modified as appropriate within the scope of the present disclosure. [Explanation of symbols]
