The floor board 15 can be stably held at the lower position.

  As described above, in the rear luggage compartment structure of the vehicle including the luggage compartment 3 provided at the rear of the compartment and the floor board 15 disposed below the cargo compartment 3, the luggage compartment 3 includes: A guide mechanism 17 is provided for holding the floor board 15 displaceably in an upper position and a lower position, and one end of the guide mechanism 17 is connected to the floor board 15 to support the floor board 15 so as to be movable up and down. A support member 19, a restricting portion 20 that supports the front end of the support member 19 to allow the other end of the support member 19 to move back and forth, and the support member 19 while supporting the floor board 15 by the support member 19. When the floor board 15 is moved up and down by swinging and displacing, the restraining part 21 that restrains the forward and backward movement locus and the holding part 22 that holds the floor board 15 in the upper position are provided. It is possible to easily perform the operation of moving the floor board 15 up and down while preventing the formation of a dead space at the bottom of the 3 and to change the design of the vertical position and the front and rear position of the floor board 15 easily. There is a point.

  That is, in the first embodiment, the rear end of the support member 19 is formed of a link member in which the middle part in the front-rear direction is restricted from moving back and forth by the restraint part 21 and the vertical movement of the front end part is restricted by the restriction part 20. The floor board 15 is pivotally supported by the front end of the floor board 15 and the rear end of the support member 19 is oscillated and displaced while the front end of the floor board 15 is supported by the support member 19. Since the front end portion of the floor board 15 is moved up and down in an oblique direction, the floor board 15 is moved up and down between the lower position and the upper position without displacing the front end portion of the floor board 15 below the lower position. Can be displaced.

  Therefore, as shown in FIG. 15, as in the conventional technique configured to circularly move the front end portion of the floor board 41 and displace it from the lower position indicated by the solid line to the upper position indicated by the phantom line, In order to prevent the front end portion of the floor board 41 and the tip end portion of the lever member 42 from interfering with the bottom portion of the floor board, that is, the rear floor panel, without taking measures such as forming an arcuate recess 43, the floor board 15 The front end can be displaced from the lower position to the upper position. For this reason, the floor board 15 is formed in FIG. 2 as needed while preventing the dead space resulting from the formation of the arcuate recess 43 at the bottom of the cargo compartment from being formed in the cargo compartment 3. The effective use space of the cargo compartment 3 can be expanded to the maximum by lowering it to the lower position shown, and when the floor board 15 is displaced up and down between the upper position and the lower position, its movement locus K can be regulated by the guide mechanism 17 so that the raising / lowering operation of the floor board 15 can be performed easily and appropriately.

  Moreover, in the first embodiment, as shown in FIG. 3, the upper surface of the floor board 15 held at the upper position and the upper end of the rear end trim 30 are installed at the same height and are displaced to the storage position. In addition, since the upper surfaces of the seat back 11 of the rear seat 2 and the floor board 15 are installed at the same height, heavy objects carried into the luggage compartment 3 from the rear opening of the vehicle body are placed on the upper surface of the floor board 15 and By smoothly sliding and displacing along the back surface of the seat back 11, there is an advantage that it is possible to facilitate taking in and out of the heavy object.

  Further, when it becomes necessary to change the design of the vertical position and the front / rear position of the floor board 15 in response to changes in the vehicle type, etc., the concave portions serving as the channel-shaped restraining portion 21 and the holding portion 22 of the cam follower 27 are provided. By changing the installation height or the installation angle of the guide member 32 provided with the above, the floor board 15 can be replaced without taking measures such as replacing each member constituting the guide mechanism 17 with a separate one. There is an advantage that the vertical position, the front-rear position, etc. can be easily changed.

  For example, as shown in FIG. 10, the installation position of the guide member 32 provided with the restraining portion 21 and the holding portion 22 is lowered by a predetermined distance from the upper standard position indicated by the phantom line to the lower position indicated by the solid line. When moved to the position, the upper position of the floor board 15 can be changed to the lower rear side by a predetermined distance Y from the standard position indicated by the phantom line. Further, as shown in FIG. 11, when the restraining portion 21 is installed in a backward inclined state, the longitudinal movement distance X between the lower position and the upper position of the floor board 15 is shown in the embodiment shown in FIG. Thus, it is possible to change the value to a larger value than the longitudinal movement distance X when the restraining portion 21 is installed in the vertical state. Further, as shown in FIG. 12, by installing the restraining portion 21 in a forward inclined state, the longitudinal movement distance X between the lower position and the upper position of the floor board 15 is as shown in the embodiment shown in FIG. When the restraining portion 21 is installed in a rearward tilt state, or when the restraining portion 21 is installed in a vertical state as in the embodiment shown in FIG. 2, it can be changed to a smaller value than the longitudinal movement distance X.

  In the first embodiment, since the rear end portion of the support member 19 is pivotally supported by the horizontal shaft 23 with respect to the front end portion of the floor board 15, the rear end portion of the floor board 15 is gripped. When the floor board 15 is moved up and down from the lower position to the upper position, the floor board 15 can be changed to an angle according to the preference of the operator. That is, the angle of the floor board 15 suitable for performing the operation of moving the floor board 15 up and down varies according to the height of the operator. For example, a tall person wants to perform an operation of moving the floor board 15 up and down while the rear end part of the floor board 15 is greatly raised, and conversely, a short person has a rear end part of the floor board 15. There is a tendency to desire to perform an operation of moving the floor board 15 up and down without significantly raising it.

  Therefore, as described above, the rear end portion of the support member 19 is pivotally supported with respect to the front end portion of the floor board 15 by the horizontal shaft 23, and the floor board 15 is changed to an angle according to the operator's preference. It is desirable that the floor board 15 can be easily lifted and lowered. Moreover, according to the above-described configuration, the front end portion of the floor board 15 according to the operation of raising the rear end portion of the floor board 15 as in the case where the front and rear intermediate portion of the floor board 15 is pivotally supported. There is an advantage that it is possible to effectively prevent the front end portion of the floor board 15 from coming into contact with the rear floor panel 9 without causing a situation where the floor board 15 is lowered.

  Further, in the first embodiment, the front board 16 is installed so as to extend to the front side of the front end of the floor board 15 supported at the upper position via the support member 19 and the holding portion 22. Therefore, when the floor board 15 in the lower position is displaced to the upper position, a gap is formed on the front side of the floor board 15 even when the floor board 15 is moved rearward by a predetermined distance X. By preventing this, there is an advantage that the entire bottom portion of the luggage compartment 3 can be efficiently used as a luggage placement surface continuous in the front-rear direction.

  The guide member 32 provided with a channel-like restraining portion 21 that restrains the back-and-forth movement trajectory of the support member 19 and a concave portion that becomes the holding portion 22 of the cam follower 27 is attached to the rear side inner panel 25. Instead of the first embodiment, as in the second embodiment shown in FIG. 13, a rearwardly inclined groove portion 33 is formed in the side trim material 28 constituting the side wall portion of the cargo compartment 3, and the rear end portion of the support member 19a is formed. The horizontal shaft 23 connected to the front end portion of the floor board 15 is slidably displaced along the inclined groove portion 33 so that the movement locus of the floor board 15 is restrained and moved up and down. Also good. In addition, a holding groove 34 that is curved in an arc from the upper end of the inclined groove 33 and extends in a front-down state is continuously provided, and the horizontal shaft 23 is introduced into the holding groove 34 to restrain its back-and-forth movement and downward movement. By doing so, it is possible to hold the floor board 15 in the upper position. According to the configuration of the second embodiment, by omitting the guide member 32, there is an advantage that the rear luggage compartment structure of the vehicle can be simplified more effectively.

There is an advantage that can be changed to.

  In addition, when the holding portion 22 is integrally connected to the restraining portion 21, when the floor board 15 is moved from the lower position to the upper position and the floor board 15 is held at the upper position, Since the rear end portion of the support member 19 can be held by the holding portion 22 as an extension of the operation of moving the floor boat 15 upward, the operation of holding the floor board 15 in the upper position is simplified. Can do. Therefore, for the operator, there is an advantage that excellent operability can be obtained in that the work of moving the floor board 15 upward and the work of holding the floor board 15 at the upper position can be performed simultaneously. .

  In the first embodiment, the front end of the support member 19 is connected by connecting the front end of the support member 19 to the lower end of the restricting portion 20 formed of a link member whose upper end is pivotally supported by the rear side inner panel 25. Since the front end is supported while allowing the portion to move back and forth, the front end portion of the floor board 15 is stably supported by the support member 19 while the front-rear direction intermediate portion of the support member 19 is restrained. 21. The floor board 15 is moved up and down smoothly between a lower position and an upper position by moving the front end of the support member 19 back and forth linearly along the upper and lower sides 21 and changing the inclination angle thereof. Can be made.

  Instead of the first and second embodiments in which the restricting portion 20 is configured by a link member pivotally supported on the side wall portion of the cargo compartment 3, the third embodiment shown in FIG. In addition, a guide groove 35 inclined slightly forward and downward is formed in the side trim member 28 constituting the side wall portion of the luggage compartment 3, and a support shaft 36 provided at the front end of the support member 19 is formed in the guide groove 35. The front end of the support member 19 may be configured to be supported while allowing the front end of the support member 19 to move back and forth by sliding and displacing along the front. According to the structure of this 3rd Embodiment, there exists an advantage that the rear part luggage compartment structure of a vehicle can be simplified more effectively by abbreviate | omitting the control part 20 which consists of the said link member.

  Further, according to the configuration of the third embodiment, the front end portion of the floor board 15 moves while descending from the highest position toward the holding portion provided at the end portion of the holding groove portion 34. By forming the guide groove 35 substantially parallel to the movement trajectory of the floor board 15 reaching the section, the movement direction of the floor board 15 and the movement direction of the support member 19 can be made substantially coincident with each other. An operator's burden at the time of raising and lowering the floor board 15 can be reduced. However, since the guide groove 35 is formed to be forwardly lowered, the guide groove portion 35 approaches the inclined groove portion 33, and the curvature radius of the locus drawn by the guide groove portion 35 is larger than the curvature of the locus drawn by the inclined groove portion 33. In the case of being small, the inclined groove portion 33 and the guide groove portion 35 are more remarkably approached, and when the support member 19 is at a predetermined position of the inclined groove portion 33, the position of the support member 19 on the guide groove portion 35 is 2. There may be more than one place and the operation may become unstable. For this reason, it is desirable that the shape of the guide groove portion 35 is a front lowering and has a curvature radius sufficiently larger than the curvature radius of the locus drawn by the inclined groove portion 33.
