[Prior art]

 Many off-road vehicles for driving on undeveloped roads such as sandy and mountainous areas have large wild animals and shrubs, snow walls on shoulders, mud walls, icicles and eaves, or low speeds in winter. A grill guard is installed to protect the human body and vehicle in the event of a collision with a person while driving.

Many of the grill guards for these purposes are main frames formed by bending a metal pipe of a required diameter for the purpose of protecting only the radiator grill into an inverted U shape to form a gate shape. As shown in FIG. 6, a side obtained by bending a metal pipe of a desired diameter in a U-shape on the left and right sides of the gate-shaped main frame M to protect the headlight and the corners of the fender, including the corners. The frame S ₁ and S ₂ are integrally formed by welding or the like.

[0004]

[Problems to be solved by the device]

 Although such known grill guards are also made of thermoplastic resin, most of them are composed of metal pipes with an outer diameter of approximately 40 to 80 mm, and the grill guard was actually impacted. In this case, it was not possible to expect a remarkable effect on the action of absorbing and absorbing the impact load due to the rigidity of the pipe itself. Therefore, there are some pipes made of soft material such as rubber that are fitted on the main metal pipes that compose the grill guard, but the soft material is simply concentric with the metal pipe. Since it is not too much, it is not possible to absorb the impact other than increasing the diameter of the soft material to make it thicker.When the soft material is thick, the grill guard itself becomes larger, and depending on the thing, the vehicle There may be illegal modifications that deviate from the size-controlled dimensions.

In view of the current situation, the present invention provides an impact absorbing material on the front portion that is easily subjected to an impact load during traveling, so as to further reduce the impact on a person or an object that comes into contact with the grille guard, and at the same time, the vehicle. The purpose of the present invention is to provide a vehicle grill guard with a simple structure that can minimize damage to the vehicle.

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the vehicle grill guard of the present invention is integrally attached to the main frame or / and the left and right of the main frame that protects the front center part of the vehicle body such as a radiator part, and the corners of headlights and fenders. The side frame, which can protect even the parts, is formed by a member having a cross-section groove type with an opening located on the front surface, and the member covers the opening and the front side surface portion connected to the opening. It is characterized in that a shock absorbing material is provided.

[0007]

[Embodiment of device]

 In the present invention, the main frame and / or the side frame is formed of a metal member such as aluminum or steel or a synthetic resin material, and has a groove-shaped member (member) having a predetermined length and width. The main frame is formed in a gate shape by bending it in an inverted U shape so that the opening of the groove is located on the front side so that the member can protect the radiator and the radiator grille. A bracket for mounting on the vehicle is provided at each of the tip parts of the parts. Further, the side frame is provided symmetrically on the side surface of the main frame, and the opening of the groove of the member is located on the front side.

This main frame and / or side frame is integrally provided with a flange of a predetermined width so as to project at a right angle to the outside along the opening edge of the member having a groove-shaped cross section. In addition, the strength of the member itself can be improved by bending the tip end edge of the mounting portion further rearward at a right angle to form a reinforcing piece, and can also be used as the mounting portion for the shock absorber.

Particularly, in the present invention, when the main frame and / or the side frame is formed of a member having a groove-shaped cross section, it is preferable that the member be buckled when the member receives an impact to reduce the impact. It is preferable that the open cross-section angle of the member is 95 to 100 °. If the angle of the open cross section is less than 95 °, the rigidity of the member itself is too high and the member does not buckle even if it receives an impact, and the impact load cannot be alleviated. Also, if the open cross-section angle of the member exceeds 100 °, the member will buckle due to the shock and the shock cannot be alleviated, but the rigidity of the member cannot be ensured and a slight shock load will occur. It is not preferable because it may deform the members.

The impact absorbing material provided in the opening of the member is formed of rubber or soft synthetic resin, and natural rubber or synthetic rubber can be used as the rubber. As the soft synthetic resin, it is preferable to use soft plastic foam such as soft polyurethane foam, soft polyvinyl chloride foam or rubber foam, which has excellent buffering property and processability, but is not limited to soft synthetic resin having elasticity. However, the type is not limited, and the elastic modulus and specific gravity of the shock absorber can be determined according to the intended use of the vehicle to which it is applied.

The shape of the impact absorbing material is not particularly limited as long as it has a width and a predetermined thickness capable of covering the opening of the member having a groove-shaped cross section and the front side surface portion connected to the opening. Is a strip-shaped cushion main body having a predetermined thickness and width capable of covering the opening and the front side surface connected to the opening, and the tip of the cushion main body at the center of the back surface of the cushion main body when mounted on the inner bottom surface of the frame. When an impact load is applied to the impact absorbing material by using an integrally protruding auxiliary cushion that has a height to contact with, the cushioning body that covers the opening of the member will not be torn and a sufficient cushioning effect will be obtained. Can be obtained.

Although there is no limitation in mounting such a shock absorbing material to the member, when a flange is formed on the member, this flange is used as a main mounting surface and the tip portion of the auxiliary cushion is While maintaining contact with the inner bottom surface of the member, the left and right ends of the cushion body are bent along the flange of the member, and the tip of the cushion body is fixed and attached to the front side surface of the member.

The cushion main body and the auxiliary cushion in the shock absorbing material may be integrally formed of a soft synthetic resin material excellent in cushioning property and workability, but for example, the cushion main body is excellent in cushioning property. The performance of the shock absorber itself may be improved by molding the auxiliary cushion with a material that is more rigid than the cushion main body and is made of a synthetic resin material. In addition, when this shock absorbing material is attached to a member, the shock load at the time of shock can be further eased by forming a gap between the side portion of the auxiliary cushion and the member, and also the cost can be reduced. it can.
