Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an upper vehicle body structure of an automobile, and particularly to an open-top structure in which at least the rear portion of the vehicle body is covered with a canopy.

(Prior art) Conventionally, open-top automobiles have been formed by covering the rear of the vehicle body to the roof with a hood, and when necessary, the hood is moved to the rear of the vehicle body and formed on the rear side of the vehicle body. A so-called convertible type device that can be folded and stored in a storage section to make it into a full oven state is generally well known.

In addition, in the case of the above-mentioned convertible type cars, when the top of the car body is covered with a hood, the sealing properties of the joints between the face and the side and front windows tend to be a problem, so recently, this A new open-top type has been proposed to solve this problem (UK published patent application No. 20).
86316). That is, in this proposal, a generally inverted U-shaped collapsible pillar is mounted between both side walls of the vehicle body so that it can rotate freely in the longitudinal direction of the vehicle body around both leg ends, and the rear part of the vehicle body behind the collapsible pillar is movable. The roof panel is covered with a canopy attached to the vehicle body from the collapsible pillar, and the roof panel is removably passed between the top of the collapsible pillar and the top of the front window.

By the way, as mentioned above, in open-top automobiles in which the rear part of the vehicle body is covered by a hood, when the hood is stretched, the face is stretched from the inside to the outside of the vehicle body to prevent the hood from flapping. A letter-shaped canopy link is provided, and when the top is folded and stored in the storage area on the rear side of the vehicle body, this canopy link is stored below the storage area together with the face.

In addition, a rear window is installed in the center of the hood to ensure rearward visibility when the hood is up, but if this rear window is made of transparent vinyl material so that it can be folded like the hood. Because vinyl materials are soft, they are easily scratched, and if they are folded repeatedly, they become cloudy and difficult to see, and tend to wrinkle and undulate, making it difficult to maintain flatness. The problem is that objects appear distorted. For this reason, glass is usually used as the rear window, and this rear window glass is supported by a window glass frame fixed to the top.

(Problems to be Solved by Screaming) However, when glass is used for the rear window of the top as described above, there are the following problems. In other words, when the top is folded and stored in a storage area on the outside of the vehicle body, the rear window glass falls into the storage area before the canopy link that stretches the top outward from the vehicle body around the storage area. It may get under the canopy link. For this reason, when the top is re-tensioned, the top cannot be tensioned smoothly, and the top may be damaged due to excessive tensioning.

Also, when the top is up, the area around the rear window glass that acts as the face is the rear window glass or window glass frame.
This causes problems such as hanging downward (inside the vehicle body), resulting in poor appearance and causing the top to flap.

The present invention has been made in view of the above, and its purpose is to restrict the movement of the rear window glass when the canopy is stowed and to prevent the rear window glass from slipping under the canopy link. Another object of the present invention is to increase the support rigidity of the rear window glass and prevent the top from sagging near the rear window glass when the top is stretched.

(Means for Solving the Problems) In order to achieve the above object, the solving means of the present invention provides an upper body structure having the following configuration in an open-top type automobile that is equipped with a canopy that covers at least the rear part of the vehicle body. Assumed. That is, the canopy has a first position where it covers the rear part of the car body with the front part stretched out, and a second position where it is moved to the side where it hangs over the car body and is folded and stored in a storage part formed on the rear side of the car body. It is movable between the two positions so that it can be moved between the two positions. A windshield frame supporting a rear window glass is fixed to the center of the canopy, and when the canopy is in the first position, it comes into contact with the inner surface of the face part and extends the canopy around the upper opening of the storage section. Approximately U that extends outward from the vehicle body and is stored below the storage area along with the face when the hood is in the second position.
A letter-shaped canopy link is provided.

In the upper body structure of an automobile having such a configuration, one end side is fixed to the rear lower end of the window glass frame, and the other end side is fixed to the upper body structure of the automobile when the hood moves between the first position and the second position. The set plate includes a set plate formed with a guide portion that slides in contact with the rear upper surface of the canopy link.

(Function) With the above configuration, in the present invention, when the top is folded and stored in the storage section on the rear side of the vehicle body, that is, when it is moved from the first position to the second position, the rear part of the window glass frame that supports the rear window glass is moved. The set plate fixed to the lower end contacts and slides with its guide portion against the rear upper surface of the canopy link, thereby restricting the movement of the rear window glass and causing the rear window glass to slide below the rear of the canopy link. This means that it will be possible to prevent this.

In addition, when the top is in the stretched state, that is, in the first position, the windshield frame is supported by the top link by the set plate, so that the supporting rigidity of the rear window glass is correspondingly increased, and the top is stretched. This will prevent the glass from sagging near the rear window glass.

Here, it is preferable that the guide part of the set plate is provided with an engaging part that engages with the canopy link so as to prevent the set plate from moving upward when the canopy is in the first position. This is preferable in terms of preventing the hood from flapping.

(Example) Embodiments of the present invention will be described below based on the drawings.

This is a generally inverted U-shaped collapsible pillar disposed near the rear part, and the collapsible pillar 4 has its left and right leg tips connected to and supported by the side walls of the vehicle body 1 via support shafts 5.5, respectively. It is provided so as to be rotatable toward the rear of the vehicle body from an upright position near the rear of the side door 3 about the support shaft 5.5.

Further, 6 is a roof panel that is removably attached between the top of the above-mentioned collapsible pillar 4 in the upright state and the top of the front window 2, and 7 is a portion of the vehicle body 1 behind the above-mentioned collapsible pillar 4 (vehicle body The hood 7 is a hood that covers the rear part of the vehicle, and as the collapsible pillar 4 rotates, the hood 7 moves to a first position (corresponding to FIG. It is movably provided between the two positions so that it can be moved to a second position (corresponding to FIG. ing.

Here, the periphery of the hood 7 is fixed around the collapsible pillar 4 and the storage section 8 of the vehicle body 1 (details will be described later), but this alone is not sufficient when driving with the hood 7 stretched. A problem arises in that the hood 7 flaps. For this reason, a top extending mechanism for supporting the top 7 so that it does not flap is provided inside the top 7, and the structure of this top extending mechanism is shown in FIGS. 3 and 4.

The above-mentioned hood extension mechanism includes an upper hood extension link 9 for extending the hood 7 upwardly from the inside to the outside of the vehicle body between the collapsible pillar 4 and a rear window glass 24 (to be described later), and an area around the upper opening of the storage section 8. Peripheral canopy links 10 are arranged along the sides of the canopy 7 to horizontally extend the lower ends of both sides and the rear end of the canopy from the inside to the outside of the vehicle body, and to reinforce the top side ridge of the canopy 7. A pair of left and right bands 11 and 11 are provided.

The band 11 is disposed through the upper canopy link 9, and one end of the band 11 is fixed to the collapsible pillar 4, and the other end is fixed to the peripheral canopy link 10 and the vehicle body 1, respectively.

When the hood 7 is moved from the first position to the second position by rotating the collapsible pillar 4 from the upright state to the rear of the vehicle body around the support shaft 5,
As the lower link 13 rotates around the support shaft 18 toward the rear of the vehicle body, the support point of the lower link 13 (the support shaft 18) is located below the support point (the support shaft 5) of the collapsible pillar 4. From the lower link 13 side to the upper link 12
By applying an upward force to the tip of the leg 12b,
The upper link 12 rotates toward the rear of the vehicle body together with the collapsible pillar 4 and rotates relative to the collapsible pillar 4 in the direction of overlapping around the support shaft 19, so that when the hood 7 is in the second position, the upper link 12 and lower link 13 are configured to be stored below the storage portion 8 together with the hood 7 and the collapsible pillar 4 in a state where they overlap with the collapsible pillar 4.

Further, the peripheral canopy link 1o has a U-shaped rear link 2o that curves toward the rear of the vehicle body, and its rear end is connected to each end of the rear link 20 via a hinge member 21,
A support shaft 22 is attached at the front end to each leg of the collapsible pillar 4 (more specifically, to the second support plate 16 fixed to the leg of the collapsible pillar 4).
When the top 7 is in the first position, the rear and front links 20.23 are connected to the periphery of the storage section 8. It extends substantially horizontally and contacts the inner surface of the top 7 to stretch the top 7 outward from the vehicle body, while at the connection point (hinge member 21) between the links 20 and 23 when the top 7 is in the second position. It is configured to be stored below the storage section 8 together with the hood 7 in a convexly folded state. Incidentally, when the canopy 7 is in the first position and the rear and front links 20, 23, that is, the peripheral canopy links 10 are located extending substantially horizontally in the peripheral part of the storage part 8,
Its position is the peripheral canopy link 10 and the collapsible pillar 4.
The hook is held by a pair of left and right bands 11 and 11 that are passed between the two.

On the other hand, as shown in FIG. 6, the top 7, which is supported by the above-mentioned hood extension mechanism and extends outward from the vehicle body, has an upper front end 7a and a side front end 7b of the periphery attached to the collapsible pillar 4. A side lower end 7C and a rear end 7d are each fixedly attached to the periphery of the storage section 8 of the vehicle body 1, and a rear window glass 24 is provided in the center of the hood 7. The peripheral edge of the rear window glass 24 is supported by a window glass frame 25 fixed to the top 7 as shown in FIG. A sealing material 26 made of rubber or the like is interposed.

The structures near the fixed portions of the side lower end 7C and rear end 7d of the canopy 7 are shown in detail in FIGS. 7 and 8, respectively. In FIG. 7, reference numeral 27 has a closed section structure surrounded by a fender panel 28, two crawler panels, and a tire house outer 30 and reinforced by a reinforcement 31. It consists of left and right side walls. The outer tire house 30 extends inward to the vehicle body, and an inner tire house 32 is connected to the inner end of the outer tire house 30. consists of a part of.

A canopy mounting plate 33 is fixed to the lower side of the inner side wall (two quarter panels) of the closed section structure 27,
The lower end 7C of the side surface of the hood 7 is attached to the hood mounting plate 33 with a bolt 34. Therefore, the lower end 7C of the side surface of the hood 7 is located below the upper opening surface of the storage section 8 of the vehicle body. It is fixed to the vehicle body at the periphery. Further, a sealing material 35 is attached to the upper end portion of the closed cross-section structure 27 (a portion corresponding to the upper opening of the storage portion 8),
When the front link 23 of the peripheral canopy link 10 extends the canopy 7 from the inside to the outside of the vehicle body, the sealing material 35 contacts the cough canopy 7 from the outside to seal this portion. Note that a seal is also provided at the joint between the top mounting plate 33 and the lower end 7C of the side surface of the top 7, and together with the sealing material 35 described above, a double seal is formed to prevent water from entering the passenger compartment. I'm trying to increase that.

Further, in FIG. 8, reference numeral 36 indicates a closed cross-sectional structure consisting of an outer panel 37 and an inner panel 38, and the cross-sectional structure 36 constitutes the upper part of the rear side wall of the storage section 8. A hood mounting plate 39 is fixed to the lower surface of the closed section structure 36, and the rear end 7d of the hood 7 is attached to the hood mounting plate 39 with bolts 40. 7d is also fixed to the vehicle body at the periphery of the storage section 8 below the upper opening surface of the storage section 8 of the vehicle body, similar to the side lower end section 7C of the hood 7 described above.

Further, a sealing material 41 is attached to the upper end of the closed cross-section structure 36 (a portion corresponding to the upper opening of the storage section 8), and the rear link 20 of the peripheral canopy link 10 connects the canopy 7 to the inside. When the hood 7 extends outward from the vehicle body, the sealing material 41 contacts the hood 7 from the outside to seal this portion. As a result, the side lower end 7 of the canopy 7 described above
As in the case of C, the top mounting plate 39 and the rear end 7 of the top 7
Double sealing is performed in cooperation with the joint with d to improve sealing performance.

As a feature of the present invention, the window glass frame 2 supporting the glue V window glass 24 at the center of the hood 7 is
As shown in FIGS. 8 and 9, one end (upper end) of a set plate 42 that is substantially parallel to the hood 7 and slopes forward and upward is fixed to the rear lower end surface of the hood 5 by a screw 43. The other end (lower end) of the set plate 42 is fixed to the upper surface of the rear link 20 of the peripheral canopy link 9 when the canopy 7 moves between the first position and the second position. Guide portion 42a that slides in contact with the backing plate 44
is formed. The abutting plate 44 is attached to the rear link 2
0, and extends in the front-rear direction in a state overlapping with the upper surface of the set plate 42. At its front end, there is a engagement formed by bending the front end rearward on both sides of the widthwise center part where the guide part 42a of the set plate 42 comes into contact and slides. Stop portions 44a, 44a are formed.

On the other hand, the guide portion 42a of the set plate 42 includes
Engagement parts 42b, 42b are formed which protrude laterally from both sides in the width direction, corresponding to the locking parts 44a, 44a of the backing plate 44, and when the top 7 is in the first position, the engagement parts 42b are formed.
, 42b is the locking portion 44. of the backing plate 44. a, 44a to prevent the set plate 42 from moving upward.

Therefore, in the above embodiment, when the top 7 is folded and stored in the storage section 8 by rotating the collapsible pillar 4 toward the rear of the vehicle body from the stretched state, that is, from the first position to the 12
When moving to the I2 position, open the rear window glass 24.
A set plate 42 fixed to the rear lower end surface of the window glass frame 25 that supports the windshield frame 25 comes into contact with the backing plate 44 on the upper surface of the rear link 20 of the peripheral canopy link 10 at its guide portion 42a and slides rearward. This prevents the rear part of the rear window glass 24 from falling below the storage section 8 before the rear link 20 of the peripheral canopy link 10, and thereby prevents the rear part of the rear window glass 24 from falling below the rear link 20 of the peripheral canopy link 10. It is possible to reliably prevent people from crawling into the area. Therefore, when the canopy 7 is re-tensioned by rotating the collapsible pillar 4 toward the front of the vehicle body, the rear window glass 24 moves above the storage section 8 before the peripheral canopy link 10 as set, and the canopy is re-tensioned. This can be done smoothly, and the canopy 7 will not be damaged due to excessive stretching of the canopy.

Further, when the top 7 is in the first position covering the rear part of the vehicle body in a stretched state, the guide portion 42 of the set plate 42
a is in contact with the front end of the backing plate 44 on the upper surface of the rear link 20, and the window glass frame 25 is now supported by the rear link 20, that is, the peripheral canopy link 10, with the set plate 42 By doing so, the support rigidity of the rear window glass 24 is increased accordingly.

As a result, it is possible to prevent the top 7 from sagging in the vicinity of the rear window glass 24, thereby improving the appearance and contributing to suppressing flapping of the top 7. In particular, the guide portion 42a of the set plate 42 is provided with engaging portions 42b, 42, and the engaging portions 42b, 42b are connected to the locking portion 44a at the front end of the backing plate 44.
, 44a to prevent upward movement of the set plate 42, it is possible to further suppress flapping of the top 7 near the rear window glass 24.

Moreover, since the configuration for obtaining the above effects is simply provided with a set plate 42 and a backing plate 44 in the cylinder, it can be easily implemented and is extremely effective. It's advantageous.

In the above embodiment, the present invention is applied to an open-top type automobile in which the vehicle body roof portion is configured with a removable roof panel 6, and the vehicle body and rear portion behind the roof panel 6 are covered with a canopy 7. However, it goes without saying that the present invention can also be applied to so-called convertible type automobiles in which a canopy covers the vehicle from the rear of the vehicle body to the roof.

(Effects of the Invention) As described above, according to the upper body structure of an open-top automobile, which is provided with a canopy that covers at least the rear part of the vehicle body, when the canopy is folded and stored in the storage section on the rear side of the vehicle body, A set plate having a guide portion that slides in contact with the canopy link can regulate the movement of the rear window glass in the central portion of Kiryu and reliably prevent the rear window glass from sliding below the canopy link. Therefore, the canopy tensioning and storing operations can be performed easily and smoothly without damaging the canopy. In addition, when the top is stretched, the window glass frame that supports the rear window glass is supported by the canopy link via the set plate, and the support rigidity of the rear window glass is increased accordingly, so the area near the rear window glass of the top is It is possible to prevent the top from sagging, and to effectively improve the appearance and suppress the flapping of the top with a simple structure.

In addition, when the guide portion of the set plate is provided with an engaging portion that engages with the canopy link so as to prevent the set plate from moving upward when the canopy is in the first position. This makes it possible to more reliably suppress flapping of the top.
