  However, in such a conventional spare tire storage device 5, the carrier member 9 to which the spare tire 6 is locked has a certain turning radius from the position where the spare tire 6 is attached and detached as shown by the solid line in the figure. And moving in an obliquely upward direction along an arc-shaped movement locus K that swells forward of the vehicle. For example, the other component 11 is placed on the movement locus K at a position indicated by a two-dot chain line in the figure. Cannot be placed.

  For this reason, when the other components 11 are provided on the vehicle body, they must be set so as to avoid the movement locus K so as to avoid the interference with the carrier member 9 and the like, and the degree of freedom of layout is limited.

  Therefore, an object of the present invention is to provide a spare tire storage device that can increase the degree of freedom of the vehicle body layout.

  The present invention has been made in view of the above circumstances, and is a spare tire storage device having a moving means for storing a spare tire in a spare tire storage section provided on the lower surface side of the vehicle body, the moving means comprising: When storing the spare tire, a tire holder for detachably locking the spare tire is moved upward to a predetermined position and then moved in at least one of the vehicle front-rear and left-right directions. Accordingly, when the spare tire is taken out from the spare tire storage portion, the tire holder is lowered with movement in at least one of the vehicle front-rear and left-right directions. The most important feature is that it is configured to move downward a predetermined distance and then further descend downward toward the vehicle. .

  According to the present invention, when the spare tire is stored by the moving means, the tire holder to which the spare tire is locked is moved a predetermined distance toward the upper side of the vehicle, and then the vehicle front-rear left-right direction As a result, the spare tire is stored in the spare tire storage unit.

  Further, when the spare tire is taken out from the spare tire storage portion, the tire holder is moved obliquely downward by being lowered with movement in at least one of the vehicle front-rear and left-right directions. Thereafter, the vehicle is further lowered toward the lower side of the vehicle, and the spare tire reaches a position where it can be attached and detached from the tire holder.

  For this reason, a space that does not interfere with the spare tire locked to the tire holder is formed around the tire holder at a location where the tire holder moves only a predetermined distance in the vehicle upward and downward directions. In addition, other parts can be arranged, and the degree of freedom in layout is improved.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  The same or equivalent parts as those in the conventional example will be described with the same reference numerals.

  The spare tire storage device according to this embodiment is a spare tire storage device having moving means for storing the spare tire 6 in a spare tire storage portion 101b or the like provided on the lower surface side 101a of the vehicle body.

  When the spare tire 6 is stored, the moving means moves the tire holder 16 holding the spare tire 6 toward the upper side of the vehicle, and the tire holder 16 is fixed from the lower surface side 3a of the rear under panel 3. After being moved within the distance, the vehicle is further moved upward in any one of the longitudinal directions of the vehicle, and is moved obliquely upward.

  In addition, when the spare tire 6 is taken out from the spare tire storage portion 101b, the moving means lowers the tire holder 16 with a movement in a direction opposite to that during storage, thereby moving the tire downward in a diagonally downward direction. After being moved, it is configured to descend toward the lower side of the vehicle.

  1 and 2 show a spare tire storage device 15 of Example 1 of the best mode of the present invention.

  First, in terms of configuration, in the vehicle 101 of the first embodiment, a substantially flat rear under panel 3 is provided on the lower surface side 101a of the vehicle body.

  On the lower surface side 3a of the rear under panel 3, there is provided a tire holder 16 for detachably locking the spare tire 6 at a position rearward of the vehicle relative to the rear cross side member member 4 and further toward the vehicle front side than the rear bumper member 17. A spare tire storage device 15 for storing in a spare tire storage portion 101b along the lower surface side 3a is provided.

  In the spare tire 6 of the first embodiment, a tire wheel 6b is fitted along the inner periphery of the tire body 6a, and the tire holder is provided at the periphery of an insertion hole 6c formed in the tire foil 6b. 16 is configured to be easily detachable.

  Further, a rear axle 18b of a rear wheel 18a located in front of the vehicle relative to the spare tire storage device 15 is extended on the lower surface side 3a in the vehicle width direction, and has substantially the same height as the rear axle 18b. As described above, the suspension member member 19 as another component is extended in the vehicle width direction and is separated from the lower surface side 3a of the rear under panel 3 by a predetermined height h1 in the vehicle vertical direction.

  The spare tire storage device 15 of the first embodiment is provided with a winding device 20 as a moving means.

  In the winding device 20 of the first embodiment, a substantially box-shaped housing 20a is fixed to the lower surface side 3a of the rear under panel 3 in the vicinity of the rear bumper device 17. A wire member 21 extends from the opening provided in the front surface of the housing 20a toward the front of the vehicle.

  One end 21 a of the wire member 21 is connected to the tire holder 16 so that the tire holder 16 is suspended.

  Further, the other end 21b of the wire member 21 is connected to the take-up roller 20b in the housing 20a, and this take-up roller is rotated via a reduction gear portion or the like by rotation of an electric motor (not shown). By rolling 20b, the wire member 21 can be wound and delivered.

  Further, in the spare tire storage device 15 of the first embodiment, when the tire holder 16 is moved upward in the vertical direction of the vehicle 101 by winding by the winding device 20, the tire holder 16 is attached to the rear under panel 3. When reaching a certain distance from the lower surface side 3a of the suspension member, that is, when reaching the upper side of the upper surface of the suspension member member 19, the upward moving force is converted into the forward moving force for moving the vehicle in the forward direction. Thus, there is provided a movement guide means for moving the spare tire 6 obliquely upward by moving in the forward direction as it further rises.

  In the first embodiment, the left and right ends are supported by a pair of left and right bracket members 23, 23 fixed to the lower surface side 3a of the rear under panel 3 as the movement guide means, and the axial extension direction is set in the vehicle width direction. A round bar-shaped sliding contact shaft portion 22 is provided along the line.

  A wire member 21 is hooked on the sliding contact shaft portion 22 from above, and when the wire member 21 is slidably contacted with the sliding contact shaft portion 22, the wire member 21 is moved approximately 90 degrees downward. Is bent.

  And the tire holder 16 is comprised by the lower end 21a of this wire member 21 so that it may suspend below a vehicle.

  Further, in the first embodiment, as the movement guide means, a foil holder member 12 formed in a downward convex shape is provided on the upper surface side of the spare tire 6 so as to be fitted to the inner surface of the tire wheel 6b.

  As shown in FIG. 1, the wheel holder member 12 of the first embodiment has a tapered side surface that is reduced in diameter toward the lower side of the vehicle, has a substantially conical shape, and is substantially centered on the upper surface side of the wheel holder member 12. A rotating connection bracket member 12b is fixed to the central base portion 12a.

  Then, the central projection 13b as one end of the link member 13 constituting the movement guide means is pivotally attached to the wheel holder member 12 by the rotation connecting bracket member 12b.

  Further, the left and right ends 13a and 13a as the other ends of the link member 13 are near the lower ends of the guide bracket members 3b and 3b fixed to the lower surface side 3a of the rear under panel 3 on the vehicle body side. Are inserted into the rotation holes 3c and 3c formed in the openings, and are pivotally attached to be freely rotatable.

  Further, claw portions 3d and 3d as stopper portions are integrally bent at left and right symmetrical positions on the vehicle rear side in the vicinity of the lower ends of the guide bracket members 3b and 3b.

  The claw portions 3d and 3d abut on the vicinity of one end 13b of a link member 13 pivotally attached to the vehicle body side, thereby allowing the wheel holder member 12 to move to the spare tire fitting position. 1 is configured to stop at a position indicated by a two-dot chain line in FIG. 1 in the vicinity of a predetermined distance h1 in the vehicle vertical direction from the lower surface side 3a of the rear under panel 3 on which the member 19 is disposed.

  When the spare tire 6 is moved up and down in the vertical direction of the vehicle 101 by winding by the winding device 20, the tire holder 16 is fixed distance from the lower surface side 3a of the rear under panel 3; In Example 1, that is, when reaching the distance h1 from the lower surface side 3a of the rear under panel 3 to the upper surface of the suspension member member 19, the wheel holder member 12 is attached to the spare tire 6 as shown by a two-dot chain line in FIG. The upper surface is fitted to the inner surface of the tire wheel 6b.

  For this reason, as the tire holder 16 is further lifted by the winding of the winding device 20, the link member 13 is rotated in the vehicle front direction so that the spare tire 6 is moved obliquely upward. It is configured.

  Further, when the tire holder 16 is moved downward together with the spare tire 6 toward the lower side in the vertical direction of the vehicle by feeding the wire member 21 by the winding device 20, the tire holder 16 is moved to the lower surface of the rear under panel 3. When the wheel holder member 12 is within the distance h1 from the side 3a, the wheel holder member 12 remains fitted to the inner surface of the tire wheel 6b on the upper surface side of the spare tire 6. Is rotated, and the spare tire 6 is moved obliquely downward.

  Then, when the tire holder 16 is separated from the lower surface side 3a of the rear under panel 3 by a distance h1, the fitting of the wheel holder member 12 to the inner surface of the tire wheel 6b is released, and the wire member 21 by the further winding device 20 is released. It is configured that the spare tire 6 is lowered toward the position just below when being delivered.

  Next, the operation of the spare tire storage device 15 of the first embodiment will be described.

  First, the spare tire 6 will be described in the order of the storing operation. In the spare tire storing device 15 of the first embodiment, the tire holder 16 is positioned at a position where the operator performs the storing operation (for example, the ground surface G). Then, the wire member 21 in the winding device 20 is pulled out.

  Then, when the tire holder 16 is locked and fixed to the peripheral edge portion of the insertion hole 6c formed in the tire wheel 6b of the spare tire 6, the winding roller 20b of the winding device 20 is not illustrated. By the rotational drive of the electric motor, the wire member 21 is rolled up through the reduction gear portion and the like (see the solid line in FIG. 1).

  At this time, since the claw portions 3d, 3d are in contact with the vicinity of the one end 13b of the link member 13, the link member 13 does not rotate, and the wheel holder member 12 is positioned at the position indicated by the two-dot chain line in FIG. Stopped.

  For this reason, after the tire holder 16 to which the spare tire 6 is locked is moved toward the upper side of the vehicle and moved to the upper side of the vehicle by a predetermined distance, that is, in the first embodiment, the suspension member member 19 is moved. When reaching the position near the predetermined distance h1 in the vehicle vertical direction from the lower surface side 3a to be disposed, the wheel holder member 12 is engaged with the upper surface side of the spare tire 6.

  Then, when the winding of the wire member 21 by the winding device 20 is continued, the inner surface of the tire wheel 6b on the upper surface side of the spare tire 6 is fitted while being guided along the tapered side surface of the wheel holder member 12. Combined.

  When the wire member 21 is further wound by the winding device 20 from this state, the link member 13 is rotated in the front direction of the vehicle with the left and right end portions 13a and 13a as rotation centers. Thus, the upward moving force is converted into a forward moving force that moves the vehicle forward. And the tire holder 16 further raises with the movement to a vehicle forward direction.

  For this reason, after the spare tire 6 is lifted upward in the vehicle, it is moved obliquely upward toward the front of the vehicle by the wheel holder member 12 and the link member 13 in the vicinity of the lower surface side 3a of the rear under panel 3. It is stored in a spare tire storage portion 101b formed above the suspension member member 19 as shown by a one-dot chain line in FIG.

  On the other hand, when the spare tire 6 is taken out from the spare tire storage portion 101b, the electric motor of the winding device 20 is rotated in the reverse direction to the winding direction, and the wire member 21 is sent out.

  When the tire holder 16 is lowered toward the vehicle lower side due to the weight of the spare tire 6 along with the feeding of the wire member 21, the tire holder 16 is within the distance h1 from the lower surface side 3a of the rear under panel 3 Since the wheel holder member 12 remains fitted to the upper surface side of the spare tire 6, the link member 13 is rotated in the vehicle rearward direction with the left and right end portions 13a and 13a as the rotation centers. The tire holder 16 is moved obliquely downward by being lowered with movement in the rearward direction of the vehicle.

  When the tire holder 16 is separated from the lower surface side 3a of the rear under panel 3 by a distance h1 or more, as shown by a two-dot chain line in FIG. 1, the link member 13 is connected to the claw portions 3d and 3d of the guide bracket members 3b and 3b. The one end 13b vicinity is contact | abutted, and rotation of the link member 13 is stopped.

  For this reason, since the wheel holder member 12 stops moving at a position indicated by a two-dot chain line in FIG. 1, only the spare tire 6 and the tire holder 16 are lowered by the dead weight of the spare tire 6 as the wire member 21 is fed. Thus, the tire wheel 6 b of the spare tire 6 is detached from the wheel holder member 12.

  As described above, the spare tire 6 is lowered by a certain distance and obliquely downward of the vehicle, and then is separated from the lower surface side 3a of the rear under panel 3 by a height h1 or more only by hanging the wire member 21. The vehicle is lowered downward, and the spare tire 6 shown by the solid line in FIG. 1 is guided to the tire attachment / detachment position (corresponding to the ground surface G in this embodiment) that can be attached / detached from the tire holder. The downward movement is stopped.

  Accordingly, since the tire holder 16 moves by a predetermined distance only in the upward and downward direction of the vehicle between the position indicated by the solid line in FIG. 1 and the position indicated by the two-dot chain line, the tire holder 16 is adjacent to the front and rear directions of the tire holder 16. Thus, a space that does not interfere with the spare tire locked to the tire holder 16 is formed, and other parts such as the suspension member member 19 can be disposed in this space, and the degree of freedom in layout is improved. .

  Further, since the tire holder 16 to which the spare tire 6 is locked is moved above the suspension member member 19 by the above-described obliquely upward and downward movement, in the first embodiment, The spare tire storage portion 101 b can be provided above the suspension member member 19.

  For this reason, for example, the spare tire storage portion 101b and the suspension member member 19 can be overlapped and juxtaposed in the vertical direction of the vehicle, reducing the longitudinal dimension of the vehicle and improving the space efficiency when storing the spare tire. In addition to being able to improve, the amount of overhang of the vehicle can be reduced, and the degree of freedom in designing the vehicle 101 can be improved.

  In addition, when the spare tire 6 is taken out from the spare tire storage portion 101b, the tire holder 16 is moved downward in the downward direction by moving the tire holder 16 in the rearward direction of the vehicle. Stop at the position where it is lowered.

  In the first embodiment, the spare tire 6 suspended by the wire member 21 at this stop position is pulled out to the rear of the vehicle, and the spare tire 6 is mounted on the tire holder 16 relatively easily at the rear of the vehicle. Desorption is also possible.

  For this reason, it is not necessary for the operator who carries out attachment and detachment to dive under the vehicle 101 and the like, and the attachment and detachment operation can be performed with a relatively easy standing posture, which is convenient for use.

  In the first embodiment, when the spare tire 6 is removed, the link member 13 is brought into contact with the claw portions 3d and 3d of the guide bracket members 3b and 3b as shown by a two-dot chain line in FIG. Has been stopped.

  For this reason, when the spare tire 6 is again locked and fixed to the tire holder 16 and is about to be stored, the wheel holder member 12 is in a standby state almost directly above the wire member 21. Therefore, the foil holder member 12 can be easily and stably fitted after the wheel holder member 12 is engaged on the upper surface side of the spare tire 6 so as to coincide with the inner surface of the tire wheel 6b.

  Thus, in the spare tire storage device 15 of the first embodiment, the link member 13 and the wheel holder member 12 as the movement guide means are generated when the wire member 21 is wound and sent out by the winding device 20. The ascending moving force and the descending moving force are converted into the moving force in the forward direction and the backward direction of the vehicle.

  For this reason, a moving trajectory that can avoid interference between the spare tire storage device 15 and other components such as the suspension member member 19 can be obtained by the winding device 20 that is one power source. A mechanism and a power source for moving in the direction are not required, and an increase in the number of parts is suppressed.

  Therefore, a space for providing these other mechanisms and power sources is not required, and the degree of freedom in the layout of other components and the degree of freedom in the design of the vehicle 101 can be improved.

  3 and 4 illustrate a spare tire storage device according to Example 2 of the embodiment of the present invention.

  Parts that are the same as or equivalent to those in the first embodiment are given the same reference numerals, and different parts will be mainly described.

  First, in terms of configuration, in the vehicle 201 of the second embodiment, a substantially flat rear under panel 3 is provided on the lower surface side 201a of the vehicle body.

  On the lower surface side 3a of the rear under panel 3, there is provided a tire holder 16 for detachably locking the spare tire 6 at a position rearward of the vehicle relative to the rear cross side member member 4 and further toward the vehicle front side than the rear bumper member 17. A spare tire storage device 115 for storing in a spare tire storage portion 201b along the lower surface side 3a is provided.

  In the second embodiment, as one of the movement guide means, the left and right ends are supported by a pair of left and right bracket members 23, 23 fixed to the lower surface side 3a of the rear under panel 3, and the axial extension direction is set. A round bar-shaped sliding contact shaft portion 22 provided along the vehicle width direction is provided.

  A wire member 21 is hung on the sliding contact shaft portion 22 from above, and when the wire member 21 is slidably contacted with the sliding contact shaft portion 22, the wire member 21 is inclined approximately 90 degrees downward. Is configured to suspend the tire holder 16 below the vehicle.

  And in this Example 2, as one of the movement guide means, in a suspended state at a position between the tire holder 16 fixed to the other end 21a of the wire member 21 and the sliding contact shaft portion 22, An interposing direction changing guide piece member 24 is provided along the longitudinal direction of the vehicle along the vehicle vertical direction.

  The direction changing guide piece member 24 has a long shape and is provided at an intermediate portion of the wire member 21.

  Further, the moving guide means of the second embodiment has a concave guide bulging member 26 as a concave guide bulging portion formed to project from the lower surface side 3 a of the rear under panel 3.

  In the concave guide bulging member 26, a guide groove is interposed between the sliding contact shaft portion 22 and the rear underpanel 3 on the vehicle body lower surface side of the vehicle 201 while being rotated. In order to form the space 25, the front and rear side vicinity portions project from the lower surface side 3 a of the rear under panel 3, and the portion corresponding to the sliding contact shaft portion 22 is provided at the approximate center in the front-rear direction. It has a curved shape with a concave side.

  Then, by the winding by the winding device 20, the direction changing guide piece member 24 is interposed inside the guide groove space 25 as shown by a one-dot chain line in FIG. 3, and the direction changing guide piece member 24 is moved in the longitudinal direction. Is rotated toward the front of the vehicle, so that the tire holder 16 is moved toward the front of the vehicle.

  For this reason, when the winding by the winding device 20 is continued, the tire holder 16 is further lifted along with the movement in the front direction of the vehicle, and is moved obliquely upward, and above the suspension member member 19. The spare tire 6 is stored in the spare tire storage portion 201b.

  Next, the operation of the spare tire storage device 115 of the second embodiment will be described.

  First, the spare tire storage device 115 according to the second embodiment will be described in the order of the storage operation of the spare tire 6. In the spare tire storage device 115 of the second embodiment, the tire holder 16 is lowered to a position where the operator performs the storage operation (for example, the ground surface G). Then, the tire holder 16 is locked and fixed to the peripheral portion of the insertion hole 6 c formed in the tire wheel 6 b of the spare tire 6.

  Next, the take-up roller 20b of the take-up device 20 is rolled through a reduction gear portion or the like by a rotational drive of an electric motor (not shown) to take up the wire member 21.

  After the wire member 21 is wound, the tire holder 16 to which the spare tire 6 is locked is moved a predetermined distance toward the upper part of the vehicle up to the vicinity of the upper surface of the suspension member member 19, that is, the lower surface of the rear under panel 3. When the tire holder 16 reaches a position separated from the side 3a by a distance h1 in the vehicle lower direction, the direction changing guide piece member 24 is connected to the sliding contact shaft portion 22 and the recess as shown by a one-dot chain line in FIG. Intrusion starts inside the guide groove space 25 formed as a fixed gap with the guide bulge portion 26.

  And this direction change guide piece member 24 turns the longitudinal direction in the vehicle front-rear direction along the curved shape of the guide groove space 25, and uses the vicinity of the upper end of this direction change guide piece member 24 as the center of rotation. The lower end portion is rotated toward the front of the vehicle, and the tire holder 16 is moved toward the front of the vehicle.

  When the wire member 21 is further wound by the winding device 20 from this state, the direction changing guide piece member 24 follows a curved shape with the lower side of the concave guide bulging member 26 being concave. Then, it stably enters the inside of the guide groove space 25 and is rotated in the vehicle front direction and stopped until it is substantially parallel to the lower surface side 3a of the rear under panel 3. For this reason, the tire holder 16 suspended from the lower end portion of the direction change guide piece member 24 by the wire member 24 is further lifted with the movement in the vehicle front direction and then stopped.

  As described above, after the spare tire 6 is lifted upward by a certain distance, the direction change guide piece member 24 rotates in the vicinity of the lower surface side 3a of the rear under panel 3 to move forward in the vehicle. 3 and is stored in the spare tire storage portion 201b formed above the suspension member member 19 as shown by a one-dot chain line in FIG.

  On the other hand, when the spare tire 6 is taken out from the spare tire storage portion 201b, when the wire member 21 is sent out by rotating the electric motor of the winding device 20 in the reverse direction to the winding direction, the tire holder 16 However, the weight of the spare tire 6 is lowered and the direction change guide piece member 24 is extracted from the guide groove space 25, and the lower end portion of the direction change guide piece member 24 is rotated rearward of the vehicle. Thus, the spare tire 6 is moved downward obliquely by being lowered with the movement in the rearward direction of the vehicle.

  Then, as shown by a two-dot chain line in FIG. 3, when the spare tire 6 reaches the vicinity of a predetermined height h1 in the vehicle vertical direction from the lower surface side 3a on which the suspension member member 19 is disposed, the direction changing guide piece member Reference numeral 24 denotes a position that is substantially directly below the sliding shaft portion 22.

  For this reason, the spare tire 6 is lowered by a certain distance toward the lower side of the vehicle and then is only suspended by the wire member 21 in a state where the spare tire 6 is separated from the lower surface side 3a of the rear under panel 3 by a height h1 or more. The vehicle is lowered downward.

  Then, when the spare tire 6 indicated by the solid line in FIG. 3 is guided to and reached a tire mounting / demounting position (corresponding to the ground surface G in this embodiment) that can be mounted / removed from the tire holder, the movement is stopped.

  Therefore, since the tire holder 16 moves by a predetermined distance only in the upward and downward directions of the vehicle between the position indicated by the solid line in FIG. 3 and the position indicated by the two-dot chain line, the tire holder 16 is adjacent to the front and rear directions of the tire holder 16. Thus, a space that does not interfere with the spare tire 6 locked to the tire holder 16 is formed, and other parts such as the suspension member member 19 can be arranged in this space, and the degree of freedom in layout is improved. To do.

  Further, since the tire holder 16 to which the spare tire 6 is locked is moved by the upward and downward movement of the suspension member member 19 above the suspension member member 19, in this third embodiment, The spare tire storage portion 201b can be provided above the suspension member member 19.

  For this reason, for example, the spare tire storage portion 201b and the suspension member member 19 can be overlapped and juxtaposed in the vertical direction of the vehicle, reducing the longitudinal dimension of the vehicle and reducing the space efficiency when storing the spare tire. As a favorable one, the amount of overhang of the vehicle can be reduced, and the degree of freedom in designing the vehicle 201 can be improved.

  Further, in the spare tire storage device 115 according to the second embodiment, the longitudinal direction of the direction change guide piece member 24 extends along the vehicle vertical direction with the direction change guide piece member 24 suspended. Therefore, the longitudinal direction of the guide groove space 25 is directed in the vehicle longitudinal direction along the curved shape of the guide groove space 25 by the winding and feeding by the winding device 20, that is, the direction changing guide piece member 24. The tire holder 16 can be moved in the front-rear direction of the vehicle by rotating the lower end portion toward the front in the vehicle with the vicinity of the upper end portion and the center of rotation.

  For this reason, the spare tire storage device 115 is configured with a relatively simple configuration and does not require a large installation space for the device. In this respect as well, the space efficiency can be improved.
