Description

[Detailed Description of the Invention] This invention relates to a lid hinge device mainly used in the trunk lid of an automobile.

In the single-ship opening/closing structure of the trunk lid of a car body, a pair of left and right hinge arms are attached to the front of the back of the lid, and each tip of the arm is pivoted to a stationary part of the car body below the back window. As a result, the lid is hinged to the vehicle body and can freely rotate to open and close.

Here, the structure of a lid hinge device that has been widely used in the past will be explained with reference to FIG. Regarding the window (glass) 20 members, the positions of each of the above-mentioned members on the vehicle body center line are indicated by numerals 1 and 2 and indicated by two-dot chain lines.

The hinge arm 3 has a shape deeply curved downward, and its rear end is fastened to the lid 1 with a bolt 4, and its front end is connected to a bracket 7 of the vehicle body panel 6 with an axle bolt 5. It is pivoted to.

By the way, according to such a conventionally structured hinge device,
When the lid 1 is closed (Figure a), the lower end of the hinge arm 3 penetrates deeply into the trunk, so there is a high risk of crushing articles stored in the trunk.
When the lid 1 is open (FIG. b), the tip of the lid 1 approaches the back window 2, so it is difficult to install a wiper in the clearance C1 near the center line of the vehicle body.

In addition, as a structural technology to solve these problems,
The structure shown in FIG. 2, that is, a structure in which the lift 1 is held in a link-like manner by two sets of rods, the hinge arm 8 and the lift arm 9, has been proposed. In this proposed structure, the hinge shaft at the tip of the hinge arm 8 is 10 is held in the guide groove 11a of the bracket 110 fixed to the vehicle body lever 6, and the free end of the lift arm 9, whose base is pivoted to the rear end of the bracket 11, is held in the middle of the hinge arm 8. The pin shaft 8a is linked to the pin shaft 8a.

By the way, according to this proposed structure, when the lid 1 is opened (Fig. b), the clear run C2 expands and a wiper can be installed, but on the other hand, the large bracket 11 and link arm are not provided. As a result, the volume inside the trunk is wasted.

The present invention was made to solve these problems, and the purpose of the present invention is to secure sufficient clearance behind the back window without reducing the useful space of the trunk. An object of the present invention is to provide a lid hinge device.

The present invention will be explained below based on the illustrated embodiments.

First, in the device of the first embodiment, as shown in FIGS. 3 and 4, the hinge arm 20 expands between its tip and base end toward the interior of the trunk covered by the lid 1. Between the tip of the extended state and the base end (described later), there is formed a round rod that bulges out toward the vehicle body panel 16 (described later) and is shallowly curved, and its base end 20a is flattened. , is fastened to the lid 1 with two bolts 12.

Further, the tip of the hinge arm 20 has both sides cut off and a hinge shaft 21 is installed horizontally, and an ear-shaped floating roller 22 is pivotally supported on the hinge shaft 21.

Next, a rail-shaped hinge base 23 is fixed to the vehicle body panel 16 as a stationary part, and this base 23 has mounting plates 24.25 on the front and top surfaces, and a drawing board 24.2.
5 and a first guide member that slidably guides the hinge shaft 21 and extends parallel to the lid 1 when the hinge arm 20 is in the closed position. A round rail 26 and a mounting plate 27 protruding diagonally downward from the rear of the mounting plate 25 near the rail 26.
and the hinge arm 20.
It is formed by a pair of parallel floating rollers 28 which become second guide members through which the curved portion of the mounting plate 24.
25 is welded to the panel 16.

Therefore, the hinge arm 20 has both rollers 28 in the middle.
It is slidably inserted between the rollers 28 and guided around the curved part by the roller 28 when opening and closing, and the floating roller 2 at the tip of the roller 28
2 is slidably inserted into the collar groove of each rail 26 as a guide member.

In the hinge device of the first embodiment configured as above,
When opening the lid 1 (FIG. a) in the closed state by operation, since the arm 20 is partially supported by the rollers 28, the roller 22 is moved to the rail 26 by the urging force of the operation.
As a result, the lid 1 moves its center of rotation rearward and rotates open in the direction of exiting the room.

Therefore, when the lid 1 is opened, the clearance C3 has a sufficient dimension, and the wiper
can be easily equipped.

Furthermore, since the hinge base 23 and the hinge arm 20 almost never enter the trunk, the trunk base can be used effectively, and the hinge arm is positioned close to the rail 26 with the floating roller 28. Since the movement trajectory is regulated, there is no need for a bracket or a link arm as in the conventional example shown in FIG.

Next, in the second embodiment shown in FIGS. 5 and 6, the hinge base 30 is a rail with only one side serving as a first guide member having the same function as that shown in FIGS. 2 and 3. 31 and an ear portion 32 disposed near the rail 31, and the ear plate 32 pivotally supports an idler roller 33 serving as a second guide member. The long plate is curved to bulge toward the vehicle body panel 16 side, and the shaft 33a of the roller 33 passes through most of the middle part of the long plate, so that when the hinge arm 34 is opened or closed, the hinge arm 34 is aligned with the same axis 33a. The long groove 34a guided by the arm 34 is opened twice, and the floating roller 33 is inserted into the flange groove of the arm 34. Furthermore, the row 236, which is pivotally attached to the hinge shaft 35 at the tip of the arm 34, is inserted into the flange groove of the arm 34. It is inserted into the collar groove.

Also in this second embodiment device, the hinge arm 34 is
The intermediate portion thereof is supported in a fixed position by a roller 33, and when the lid 1 is rotated to open, the hinge shaft 35 moves backward within the rail 31, and is set in a position where the lid 1 can be opened in a direction away from the room. Ru.

Therefore, the operation and effects of the device are no different from those of the first embodiment.

As detailed above, according to the lid hinge device according to the present invention, the hinge shaft is slidably held by the guide member of the immovable part near the guide member, and the intermediate part of the hinge arm is slidably held. Since the device is configured to be freely supported by a stationary part, the center of rotation moves backward when the lid is rotated to open, providing sufficient clearance to the rear of the back window, and when the lid is opened, the lid and vehicle body are It is possible to obtain sufficient clearance between the lids, and there is no need to provide special brackets, link arms, etc., which has the effect of improving the ease of mounting the lid.
