Description

[Detailed description of the invention] In an automobile body structure consisting of a chassis frame and a cabin, the area of the mount that restrains the cabin to the chassis frame is small, so when a shock is applied due to a collision, etc., the occupant When a load is applied to the restraining seat belt, a problem occurs in which the cabin to which the seat belt is fixed tilts forward.

In order to prevent the cabin from tilting forward in the event of a collision, locking metal fittings fixed to arbitrary locations on the cabin and the chassis frame are provided opposite each other at an arbitrary interval, and the locking portion at the tip of each locking metal fitting is installed at an arbitrary interval. A structure for a mount part of a cabin in which the mount part is detachably locked is proposed in Japanese Patent Publication No. 49-49539.

However, in the above proposal, the locking metal fittings must be provided independently for the cabin and the chassis frame, and the locking metal fittings must be placed facing each other between the cabin and the chassis frame, which requires assembly work. must be carried out in a narrow space,
There are some drawbacks in terms of workability.

Further, since the impact force acts on the locking member as a tensile force, stress concentration acts on the locking portion as a bending load, which is disadvantageous in terms of strength.

The present invention was proposed in order to eliminate such drawbacks, and includes a stopper bracket at one end of the cabin side mount bracket and the chassis frame side mount bracket in the mount portion that connects the chassis frame and the cabin. and a locking member of the stopper bracket is disposed on the other of the two mount brackets and the chassis frame, respectively, at a distance from the stopper bracket at the front and rear of the bracket. This relates to the structure of the mount part of the cabin.

In this case, as described above, one end of the stopper bracket is fixed to one of the mount brackets of the cabin side mount bracket and the chassis frame side mount bracket, and the stopper bracket is fixed to the other of the two brackets and the chassis frame, respectively. Since locking members for both brackets are located at the front and rear of the brackets and are spaced apart from each other, when the cabin tries to tilt forward due to the impact of a collision, the locking members for the stopper brackets are disposed. The respective locking members collide in the front and rear to lock the stopper bracket at the relevant position, thus preventing forward tilting or forward movement of the cabin via the stopper bracket and the respective locking members, This greatly improves safety in the event of a collision.

According to the present invention, as described above, the impact force acting upon a collision is received by the shear resistance of the stopper bracket and the locking member, which is advantageous in terms of strength compared to the conventional one. Moreover, since each of the above-mentioned members is attached to the side surface of the body mount bracket, the assembly work is easy.

Furthermore, since a gap is provided between the stopper bracket and each of the locking parts, the relative displacement between the chassis frame and the cabin during normal driving is absorbed by this gap, and the function of the mount part is improved. is not impaired.

The present invention will be described below with reference to illustrated embodiments.

Reference numerals 1 and 2 denote a cabin and a cargo box respectively mounted on a chassis frame 3. A chassis side bracket 4 is fixed to the chassis frame 3 by welding.

A cabin side mount bracket 6 welded to the floor panel 5 is attached to the chassis frame side mount bracket 4 with mounting rubber 7 and bolts 8,
The stopper bracket 10 is connected via a nut 9, and the upper end of the stopper bracket 10 is fixed to the upper part of the outer surface of the cabin side mount bracket 6 via a bolt 11 and a nut 12.

A locking recess 10a and a hook portion 1 are provided at the front edge of the intermediate portion and the rear edge of the lower end of the stopper bracket 10, respectively.
0b is provided on the outer surface of the chassis frame side mount bracket 4 and the chassis frame 3.
The stopper brackets 10 are respectively disposed on the outer surfaces of the stopper brackets 10.
Pins 13 and 14 are installed at the front and rear of the recess 10a and the hook 10b with gaps between them. The pins 13 and 14 constitute the locking member, and each pin 13 and 14 has a flat head at its tip to prevent the stopper bracket 10 from passing through.

Since the illustrated embodiment is constructed as described above, the clearance between the pins 13 and 14 and the stopper bracket 10 prevents relative displacement between the chassis frame 3 and the cabin 1 during normal driving. is absorbed, and the function of the mount is not impaired.

Further, in the event of a collision, when the cabin 1 tries to tilt forward due to the load from the seat belt, the cabin side mount bracket 6 and the stopper bracket 10 fixed thereto tilt forward, causing the lock of the bracket 10 to tilt forward. The locking recess 10a and the hook portion 10b collide with each of the pins 13, 14,
14, the stopper bracket 10 is locked in this position, and accordingly, the cabin 2 is also prevented from tilting forward. Note that after the pin 14 is locked to the hook portion 10b, the stopper bracket 10
is prevented not only from moving forward, but also from moving upward.

FIG. 4 shows another embodiment of the present invention, in which a stopper bracket 10 is arranged upside down, its lower end is fixed to the chassis frame 3 with bolts 11' and nuts, and its upper end rear face and middle part front face Pins 14' and 13' are spaced apart from each other on the rear and front surfaces of the hook portion 10b and the locking recess 10a provided on the outer surface of the cabin side mount bracket 6 and the chassis frame side mount bracket 4, respectively. It is installed protrudingly.

In the drawings, parts equivalent to those of the above embodiment are given the same reference numerals.

FIG. 5 shows still another embodiment of the present invention, in which the upper end of the stopper bracket 10 is fixed to the rear side of the cabin side mount bracket 6 via a bolt 11'' and a nut so that the stopper bracket 10 is located at the rear of the mount part. , pins 14'' fixed to the rear surface 4a of the chassis frame side mount bracket 4 and the lower surface of the chassis frame 3 are arranged at intervals on the front surface of the mount bracket 10 and the rear surface of the tip hook portion 10b, respectively. ing. At this time, the rear surface 4a of the chassis frame side mount bracket 4 and the pin 14'' constitute a locking member of the stopper bracket.

In the drawings, parts that are equivalent to each of the above embodiments are given the same reference numerals.
