Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a vehicle grille guard mounted to protect headlights and radiators provided on a front surface of a vehicle, as well as a corner portion of a fender.

[0002]

[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. 7, a side formed by bending a metal pipe of a required diameter in a U-shape on the left and right sides of the gate-shaped main frame M to protect the headlights and the corners of the fenders. 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.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the vehicle grill guard of the present invention is a member with a cross-section groove type whose opening is located in the front part of the main frame that protects the front center part of the vehicle body such as the radiator part. A side frame that is integrally attached to the left and right and that can protect the corners of the headlight and / or the fender is formed of a pipe material, and covers the opening of the member and the front side surface that is connected to the opening. In addition to providing a shock absorbing material, the pipe material is provided with a shock absorbing material so that the impact direction becomes thickest.

[0007]

[Embodiment of device]

 In this invention, the main frame is made of a metal 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.

One of the side frames is attached to the side surface of the main frame by welding or fusion so as to be bilaterally symmetrical, and is made of a pipe material made of the same material as the member. This pipe material may have a shape that only protects the headlights or a shape that can protect even the corners of the fender. For example, one pipe material may be bent in a U-shape, and the vicinity of the U-shape portion of the U-shape pipe may be bent to one side along the corner portion of the fender.

The main 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, and serves as a mounting portion for the shock absorbing material. The strength of the member itself can be improved by bending the front edge of the member further to the rear at a right angle to form a reinforcing piece, and can also be used as a mounting portion for the shock absorbing material.

In particular, in the present invention, when the main frame is composed of a member having a groove-shaped cross section, it is preferable to buckle the member when the member receives an impact so that the impact can be alleviated. The sectional angle is preferably 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 that can cover 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.

There is no limitation on the mounting of such an impact absorbing material to the member, but when a flange is formed on the member, this flange is used as the 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 molded as a whole with a soft synthetic resin material having excellent cushioning properties and processability. For example, the cushion main body has excellent cushioning properties. 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.

Further, the impact absorbing material is attached to the sub-frame so that the front surface portion becomes the thickest when it is attached to the side frame. Specifically, the impact absorbing material has a cylindrical shape. It is formed by offsetting the engagement holes that have an inner diameter that matches the outer diameter of the main frame and side frame to be applied to the front part, and the front part becomes the thickest, and the thickness gradually decreases from the side to the back direction. In addition, a slit is formed in the rear part along the axial direction.The slit is used to cover the main frame or side frame from the front part, and if necessary, the shock absorber. Is fixed to the main frame or side frame by means such as adhesion.

The impact absorbing material is capable of further mitigating the impact at the time of collision by forming a sufficient thickness in the impact direction. Therefore, it is necessary to form a sufficient thickness in the impact direction. If possible, the cross-sectional shape is not limited to the round shape, and may be a trapezoidal shape.

[0017]

[Action]

 In the vehicle grill guard of this invention, the main frame mounted on the front of the vehicle is composed of a cross-section groove type member, and the shock absorbing material can be mounted on the opening of this member. By selecting the material, elastic modulus, specific gravity, etc. of the shock absorber depending on the application, it is possible to significantly mitigate the shock received by the person or object that collides with the grill guard, and at the same time minimize the damage to the vehicle body. it can. Also, since the side frame has the thickest part in the direction of impact, the impact on people and objects that collide with the gull guard can be greatly mitigated, and at the same time damage to the vehicle body can be minimized. . In particular, the off-road 4WD vehicle has the characteristics that the front part of the vehicle body has high rigidity and the position of the vehicle body is also high. Therefore, as shown in FIG. Since it is the height of the vehicle, it is most effective in absorbing and relaxing the impact on a person in the case of a low-speed collision with a person.
