The battery 10 has a corner portion constituted by an upper surface of the battery 10 and a side surface farthest from the side frame 60 among the side surfaces of the battery 10, that is, a corner portion extending along the longitudinal direction of the vehicle body. The clamp plate portion 31 is arranged so that the clamp plate portion 31 covers almost the entire corner of the battery 10. The upper restricting portion 35 provided in the clamp plate portion 31 restricts the battery 10 from moving upward in the height direction of the vehicle body, and the outer restricting portion 36 provided in the clamp plate portion 31 is provided outside the width direction of the vehicle body. That is, the battery 10 is restricted from moving in a direction away from the side frame 60.

  One fitting hole 32 that penetrates the clamp plate portion 31 along the width direction of the vehicle body is formed in the center portion of the outer regulation portion 36 in the length direction of the vehicle body. In addition, the clamp 30 includes two protrusions that protrude from the outer regulation portion 36 toward the outer side in the width direction of the vehicle body. Each of the front protrusion 33a that is one protrusion and the rear protrusion 33b that is the other protrusion has a flat plate shape that extends along the length direction of the vehicle body and the width direction of the vehicle body. . The front protrusion 33a and the rear protrusion 33b are arranged along the length direction of the vehicle body with the portion where the fitting hole 32 is formed interposed therebetween.

  The holding portion 50 is fitted in the fitting hole 32. The holding part 50 includes a base part 51 fitted in the fitting hole 32 and a rotating part 52 rotatably supported by the base part 51. The rotating portion 52 includes a shaft portion extending along the width direction of the vehicle body and a lever protruding from the shaft portion, and the lever rotates about the shaft portion as a rotation shaft.

  The battery cover 40 includes an upper cover 41 that faces the bottom plate portion 21 of the support base 20, and an outer cover 42 that extends downward from the upper cover 41 and has a plate shape that faces the side frame 60.

  A shaft insertion hole 43, which is a through hole through which the rotation part 52 is passed, is formed at the center of the outer cover 42 in the longitudinal direction of the vehicle body. The size and shape of the shaft insertion hole 43 prohibits the lever from passing through the shaft insertion hole 43 when the lever of the rotating portion 52 is positioned at a holding position where the battery cover 40 is held by the lever. The lever is allowed to pass through the shaft insertion hole 43 when the lever is positioned at a release position where the holding of the battery cover 40 by the lever is released.

  Also, the outer cover 42 has a front projection insertion hole 44a that is a through hole through which the front projection 33a of the clamp 30 passes, and a rear projection insertion that is a through hole through which the rear projection 33b of the clamp 30 passes. A hole 44b is formed. The front protrusion insertion hole 44a and the rear protrusion insertion hole 44b are arranged along the length direction of the vehicle body with the portion where the shaft insertion hole 43 is formed therebetween.

  The front protrusion insertion hole 44a is a long hole extending along the length direction of the vehicle body, and the size and shape of the front protrusion insertion hole 44a are the front protrusions that are passed through the front protrusion insertion hole 44a. 33a restricts movement along the height direction of the vehicle body and movement along the length direction of the vehicle body. The rear projection insertion hole 44b is also a long hole extending along the length of the vehicle body, and the size and shape of the rear projection insertion hole 44b are passed through the rear projection insertion hole 44b. Further, the rear projection 33b is restricted from moving along the height direction of the vehicle body and from moving along the length direction of the vehicle body.

  When the battery cover 40 is attached to the support base 20 and the clamp 30, the rotating portion 52 is passed through the shaft insertion hole 43 with the lever in the release position, and the front protrusion 33a is inserted into the front protrusion insertion hole 44a. The rear protrusion 33b is passed through the rear protrusion insertion hole 44b. From this state, the lever of the rotating unit 52 is rotated, and the lever is displaced from the release position to the holding position, whereby the position of the battery cover 40 is held.

  In a state where the battery cover 40 is attached, the upper cover 41 covers the upper surface of the battery, and the outer cover 42 covers a part of the side surface of the battery 10 that is farthest from the side frame 60. A portion of the upper cover 41 close to the side frame 60 is supported by support portions 25 a and 25 b included in the side plate portions 22 a and 22 b of the support base 20.

The support 20 and the clamp 30 are preferably made of metal, and the battery cover 40 and the holding unit 50 are preferably made of resin.
A detailed configuration of the holding unit 50 will be described with reference to FIGS. 2 and 3.

  As shown in FIG. 2, the base portion 51 includes a claw portion 53, and the holding portion 50 is fixed to the clamp 30 when the claw portion 53 is hooked in the fitting hole 32 of the outer regulating portion 36. Further, the base 51 includes a bearing portion 54 that rotatably supports the rotating portion 52.

  The rotating part 52 includes the shaft part 55 and the lever 56 which is an example of a widened part. The lever 56 is connected to the shaft portion 55 on the side opposite to the clamp plate portion 31, and at least a part of the lever 56 has a width greater than the width of the shaft portion 55 in the radial direction of the shaft portion 55. The shaft portion 55 is supported by the bearing portion 54 and rotates within a range of 90 degrees, and the lever 56 rotates together with the shaft portion 55. When the battery cover 40 is attached, the shaft portion 55 and the lever 56 are inserted into the shaft insertion hole 43. The lever 56 is extended to the outside of the shaft insertion hole 43, and the shaft portion 55 is surrounded by the outer cover 42 of the battery cover 40 that defines the shaft insertion hole 43.

  As shown in FIG. 3, when viewed from the outside in the width direction of the vehicle body, the lever 56 has a substantially rectangular shape extending in one direction. As the shaft portion 55 rotates, the lever 56 rotates within a range of 90 degrees between the angle at which the lever 56 is positioned at the release position and the angle at which the lever 56 is positioned at the holding position. The position of the lever 56 when the extending direction of the lever 56 coincides with the length direction of the vehicle body is the release position, and the position of the lever 56 when the extending direction of the lever 56 coincides with the height direction of the vehicle body is maintained. Position. In FIG. 3, the lever 56 when in the holding position is indicated by a two-dot chain line.

  When the lever 56 is in the release position, the lever 56 is accommodated in a region where the shaft insertion hole 43 is formed as viewed from the outside in the width direction of the vehicle body. In this state, the lever 56 is inserted and removed from the shaft insertion hole 43. On the other hand, when the lever 56 is in the holding position, a part of the lever 56 protrudes from the region where the shaft insertion hole 43 is formed when viewed from the width direction of the vehicle body. At this time, since the lever 56 is hooked on the outer cover 42 of the battery cover 40 that defines the shaft insertion hole 43, the lever 56 cannot be removed from the shaft insertion hole 43. That is, the holding portion 50 holds the battery cover 40 by sandwiching the outer cover 42 of the battery cover 40 between the clamp plate portion 31 and the lever 56 around the shaft portion 55 passed through the shaft insertion hole 43. To do.

  The lever 56 is locked at one of the release position and the holding position, and the shaft portion 55 is provided with the bearing portion 54 so that a predetermined force is required to rotate the lever 56 from these positions. It is preferable to be supported by. According to this, since the lever 56 is prevented from being positioned between the release position and the holding position when the battery cover 40 is attached or the vehicle is traveling, the holding function of the battery cover 40 by the holding unit 50 is reduced. It can be suppressed.

  With reference to FIG. 4, the effect | action which the holding structure of the battery cover of this embodiment brings is demonstrated. 4 shows that the clamp 30, the battery cover 40, and the holding portion 50 are assembled, and the holding portion 50 and the two protrusions 33a and 33b are surrounded by the width direction of the vehicle body when the holding portion 50 is in the holding position. It is the figure seen from this, Comprising: The lever 56 of the holding | maintenance part 50 is shown with the dashed-two dotted line.

  As shown in FIG. 4, in the height direction of the vehicle body, a distance between the shaft portion 55 of the holding portion 50 passed through the shaft insertion hole 43 and the upper end portion of the outer cover 42 is a distance d1A. The distance between the shaft portion 55 and the lower end portion of the outer cover 42 is a distance d2A. Further, in the length direction of the vehicle body, a distance between the shaft portion 55 and the front end portion of the outer cover 42 is a distance d3A, and a distance between the shaft portion 55 and the rear end portion of the outer cover 42 is a distance d4A. And

  In addition, a gap is formed between the front protrusion 33a and the outer cover 42 in a state where the front protrusion 33a is passed through the front protrusion insertion hole 44a. At this time, in the height direction of the vehicle body, the distance between the upper surface of the front projection 33a and the upper end of the outer cover 42 is a distance d1B, and the distance between the lower surface of the front projection 33a and the lower end of the outer cover 42 is set. The distance is a distance d2B. Further, in the longitudinal direction of the vehicle body, the distance between the front end surface of the front projection 33a and the front end of the outer cover 42 is a distance d3B, and the rear end surface of the front projection 33a and the rear end of the outer cover 42 Is a distance d4B.

  Similarly, a gap is formed between the rear projection 33b and the outer cover 42 in a state where the rear projection 33b is passed through the rear projection insertion hole 44b. At this time, in the height direction of the vehicle body, the distance between the upper surface of the rear projection 33b and the upper end of the outer cover 42 is a distance d1C, and the distance between the lower surface of the rear projection 33b and the lower end of the outer cover 42 is Let the distance between them be the distance d2C. Further, the distance between the front end surface of the rear projection 33b and the front end of the outer cover 42 in the length direction of the vehicle body is a distance d3C, and the rear end surface of the rear projection 33b and the rear side of the outer cover 42 A distance between the end portions is a distance d4C.

  A distance d1A between the shaft portion 55 and the outer cover 42 is larger than distances d1B and d1C between each of the two protrusions 33a and 33b and the outer cover 42. Similarly, the distance d2A between the shaft portion 55 and the outer cover 42 is larger than the distances d2B and d2C between each of the two protrusion portions 33a and 33b and the outer cover 42, and the shaft portion 55 and the outer cover 42 are. Is larger than the distances d3B and d3C between each of the two protrusions 33a and 33b and the outer cover 42. The distance d4A between the shaft portion 55 and the outer cover 42 is larger than the distances d4B and d4C between each of the two protrusions 33a and 33b and the outer cover 42.

  Thus, in the height direction of the vehicle body, the distance between the shaft portion 55 and the outer cover 42 is larger than the distance between each of the two projections 33a and 33b and the outer cover 42. Therefore, when the vehicle travels, when vibration in the height direction of the vehicle body occurs, the outer cover 42 contacts the two protrusions 33a and 33b, and the outer cover 42 is prevented from contacting the shaft portion 55. It is done.

  Further, in the longitudinal direction of the vehicle body, the distance between the shaft portion 55 and the outer cover 42 is larger than the distance between each of the two projections 33a and 33b and the outer cover 42. Therefore, when the vehicle travels, when vibration in the longitudinal direction of the vehicle body occurs, the outer cover 42 contacts the two protrusions 33a and 33b, and the outer cover 42 is prevented from contacting the shaft portion 55. It is done.

  As a result, the load resulting from the vibration in the height direction and the length direction of the vehicle body is applied to the two protrusions 33a and 33b, and the load applied to the holding unit 50 is suppressed. Although the holding portion 50 receives vibrations in the width direction of the vehicle body, the vibrations in the width direction of the vehicle body are small compared to vibrations in the height direction and the length direction of the vehicle body. The load applied to the holding unit 50 is small as compared with the case of receiving vibration in the vertical direction or the length direction.

  As described above, in the present embodiment, the configuration that mainly receives the load caused by the vibration of the vehicle body and the configuration that controls the holding state of the battery cover 40 are divided into the two projecting portions 33a and 33b and the holding portion 50. Therefore, it is possible to suppress the load due to the vibration of the vehicle body from being applied to the holding portion 50. As a result, since the holding function of the battery cover 40 by the holding unit 50 can be suppressed from being reduced due to vibration, the reliability with respect to the attachment of the battery cover 40 can be enhanced. In addition, since the two protrusions 33a and 33b that receive the load are made of metal and the holding portion 50 that is difficult to receive the load is made of resin, it is possible to increase the strength against the load and reduce the cost required for manufacturing.

  When the load resulting from the vibration of the vehicle body is heavily applied to the configuration for controlling the holding state of the battery cover 40 as in the prior art, the configuration for controlling the holding state needs to be configured to withstand the vibration of the vehicle body. there were. In this case, the holding structure of the battery cover 40 becomes complicated, and when the battery cover 40 is attached, the force required to operate the configuration for controlling the holding state often increases. On the other hand, according to the present embodiment, it is possible to increase the reliability of the attachment of the battery cover 40 while suppressing the magnitude of the force required for the operation of the holding unit 50.

  In the present embodiment, since the holding structure for the battery cover 40 is provided in the portion where the clamp 30 and the battery cover 40 overlap, this holding structure is applicable regardless of the shape of the end of the battery cover 40. can do. For example, as shown in FIG. 5, even when the outer cover 42 is formed in a shape that covers the entire side surface of the battery 10 that is farthest from the side frame 60, The structure for holding the battery cover 40 can be applied. Therefore, even when there are a plurality of types of shapes of the battery cover 40, it is not necessary to change the configuration of the holding structure for each shape of the battery cover 40. Therefore, the battery cover 40 can be easily replaced with a cover having a different shape. be able to. Further, since the holding structure is provided at the position farthest from the side frame 60, the holding structure can be easily operated.

As described above, according to the battery cover holding structure of the present embodiment, the effects listed below can be obtained.
(1) Apart from the holding part 50 for controlling the holding state of the battery cover 40, protrusions 33a and 33b for restricting the movement of the position of the battery cover 40 are provided in the longitudinal direction and the height direction of the vehicle body. Therefore, it is possible to suppress the load due to the vibration of the vehicle body from being applied to the holding unit 50. As a result, the holding function of the battery cover 40 by the holding unit 50 is reduced due to the vibration of the vehicle body, and the holding of the battery cover 40 is prevented from being released, so that the reliability of the attachment of the battery cover 40 is improved. be able to.

  (2) The distance between the shaft portion 55 and the battery cover 40 in the height direction of the vehicle body and the length direction of the vehicle body is the distance between each of the two protrusions 33a and 33b and the battery cover 40. Bigger than. Therefore, since the load resulting from the vibration in the height direction and the length direction of the vehicle body is applied to the two protrusions 33a and 33b, it is possible to accurately suppress the load from being applied to the holding unit 50.

  (3) The shaft insertion hole 43 allows the insertion of the lever 56 at the release position and prohibits the insertion of the lever 56 at the holding position. Since the lever 56 is displaced between the holding position and the release position by the rotation of the lever 56, the battery cover 40 can be easily switched between being held and released. As a result, since the certainty of such switching is increased, the reliability with respect to the attachment of the battery cover 40 can be further increased.

  (4) The two protrusion insertion holes 44a and 44b are formed at positions sandwiching the shaft insertion hole 43 in the longitudinal direction of the vehicle body, and the two protrusions 33a and 33b sandwich the holding part 50 in the longitudinal direction of the vehicle body. In the position. According to such a configuration, since the load caused by the vibration of the vehicle body is distributed and applied to the two protrusions 33a and 33b sandwiching the holding unit 50, it is possible to accurately suppress the load from being applied to the holding unit 50. The load on the two protrusions 33a and 33b is prevented from being biased.

  (5) The two protrusions 33a and 33b have a flat plate shape that extends along the width direction and the length direction of the vehicle body. When the vehicle is traveling, large vibrations are likely to occur in the height direction of the vehicle body. According to the above configuration, the two protrusions 33a and 33b are subjected to vibration in the height direction of the vehicle body in a plane, and thus the load on the two protrusions 33a and 33b is reduced. Further, if the two protrusions 33a and 33b are flat, the clamp 30 can be easily manufactured because the two protrusions 33a and 33b can be formed integrally with the clamp plate 31 without being separately joined. Become.

(Modification)
The above embodiment can be implemented with the following modifications.
-The number and position of the projection part which the clamp 30 has are not restricted to the aspect of the said embodiment. The number of protrusions may be one, or three or more. Further, the protrusion may be provided at a position sandwiching the holding portion 50 in the height direction of the vehicle body, for example.

-The shape of the projection part of the clamp 30 is not restricted to the shape of the said embodiment. For example, the protrusion may be formed in a columnar shape.
The configuration of the holding unit 50 is not limited to the configuration of the above embodiment as long as the holding state of the battery cover 40 is releasably held. The holding portion 50 holds the battery cover 40 by sandwiching the battery cover 40 between the clamp plate portion 31 and the lever 56 around the shaft portion 55 passed through the shaft insertion hole 43, and the displacement of the lever 56 is changed. Therefore, any configuration may be used as long as the holding of the battery cover 40 is released. For example, the lever 56 is formed in a disk shape whose width in the radial direction is larger than that of the shaft portion 55, and the shaft portion 55 and the base portion 51 are screwed together, whereby the battery is interposed between the clamp plate portion 31 and the lever 56. The cover 40 may be sandwiched. In this case, the position of the lever 56 when the shaft portion 55 and the base portion 51 are screwed together is the holding position, and when the screwing is released and the shaft portion 55 and the lever 56 are removed from the base portion 51, the lever 56 is located at the release position.

  The support 20 is not limited to the side frame 60 but may be attached to a cross member, or may be attached to a body when the vehicle is a vehicle such as a passenger car that does not have such a frame. In short, the mounting surface on which the support base 20 is mounted may be set to any part of the vehicle body as long as it is a vertical surface. At this time, a direction parallel to the mounting surface and orthogonal to the vertical direction is set as the first direction, and a direction orthogonal to the first direction and the vertical direction is set as the second direction. The clamp plate portion 31 extends along the first direction, and the protrusions 33a and 33b protrude along the second direction. The protrusions 33a and 33b restrict the movement of the position of the battery cover 40 in the vertical direction and the first direction. According to such a configuration, since the load caused by the vibration of the vehicle body is distributed and applied to the protrusions 33a and 33b and the holding portion 50, the holding portion 50 receives the load caused by the vibration in all directions. In comparison, it is possible to suppress the load due to the vibration of the vehicle body from being applied to the holding unit 50. Therefore, the reliability with respect to the attachment of the battery cover 40 is improved.
