Description

Description

Protective device for the front bumper of the car.

Device object

The utility model relates to the field of automotive industry, in particular to the protective devices of the front bumper of a car.

As you know, the front bumper of a car is subject to frequent damage when parking the car, when maneuvering in confined spaces. Damage can occur when the car is in contact with the front bumper with a high curb stone and other structures protecting the road, as well as with other cars. Known protective devices for the front bumper of a car have a bulky design in the form of a protective device located in front of the bumper of the car and require the installation of a complex fastener system or have a low protective function.

Known protective and decorative device for the bumper, which is mounted on the mounts of the license plate (patent JPS 61196844, NISSANMOTORCOLTD). However, this device has a rather complicated design and there is no possibility of hard mounting the vehicle number in this protective device.

From US Pat. No. 4,917,426 (Chrysler Corporation), a bumper guard is known which is mounted along the entire length of the bumper, capturing the side portions thereof. To mount the license plate, an additional holding device is installed on top of the bumper protective device, while the car license plate is not fastened with screws, screws or other fasteners, but simply inserted into the holding device and is easily removable. However, this device cannot be installed on any car, since its installation requires the presence of a certain configuration of a bumper on the car, which provides for the possibility of mounting this protective device. Thus, under this protective device, a special bumper should be made, which relates to the industrial production of parts for automobiles. Also, the easily removable method of installing a car license plate has a drawback - when driving at high speed and / or driving on rough roads, vibration may occur and the license plate may fall out of the device holding it.

From US Pat. No. 5,904,386 (BUCHMAN, DARREN), a bumper guard is known, which is elastic caps for license plate mounting screws made of rubber or the like. However, this protective device is aimed at providing protection for the bumper of the car when attaching a license plate to it. This device is not able to protect the front bumper of the car in contact with an obstacle.

Known protective device for a bumper made of elastic material (rubber, foam rubber) in the form of a logo that is mounted on the bumper (application US 20090026775, Gieorgii Bogdan). However, this device has a weak protective function and to a greater extent advertises car manufacturers. Mounting this device involves the use of special hardware.

The closest technical solution is the application US 20090284030 (GaryRein) for a protective device for the bumper, which is mounted on the bumper at the place of installation of the license plate and consists of two parts, one of which is a license plate holder, and the other is an elastic buffer, while the buffer can be made of elastic material (rubber, foam rubber). However, this device is located in the form of a protective device in front of the bumper of the car, has a massive structure and changes the appearance of the bumper from an aesthetic point of view. This design does not imply mounting a license plate on it. In addition, the installation of a fencing device, not provided by the manufacturer, requires the introduction of appropriate marks in the registration documents for the car.

The purpose of this utility model is to create a protective device for the front bumper of the car, free from the above disadvantages and corresponding to the requirements of aesthetics.

A design feature of the proposed solution is that it performs the function of both fixing the license plate to the front bumper of the car and protecting this bumper from mechanical damage in the event of collision with obstacles at low speeds (5-15 km / h) and, in addition, due to the lack of a walling on the bumper, it organically fits into the design of the car, which enhances its aesthetic appeal.

The patented utility model can be made of various non-metallic elastic plastic materials, for example, in the form of an open, hollow rectangular frame made of an elastic material made of rubber-cord material characterized by high strength, effective compensation properties, the ability to reduce dynamic loads and high damping ability, is the ability to convert energy into heat during sudden deformations due to shock loads during dynamic tolknoveniyah obstacle.

A design feature of the proposed device is the concavity inward of its opposite long sides on the front side and the absence of concavity on the side of registration number adjoining to the seat of the protective device and to the front bumper of the car. Due to the mentioned design features, the device fits snugly with its entire rear surface to the bumper of the car, and on the front side it has the similarity of a spring with end parts bent upwards.

The differences also lie in the fact that the rectangular frame has a maximum thickness along its short sides, which can be in the range of 60-80 mm and minimum along the middle part of the long sides, which is in the range of 8-15 mm with a gradual increase as you approach lateral (short) sides of the frame, reaching a maximum of 40-60 mm, the thickness of the rectangular frame across the long and short sides of the frame is in the range of 30-40 mm. In this case, the outer dimensions of the frame can be in length within 580-585 mm, and in width - 167-175 mm.

Another difference is that the middle part of the short sides of the rectangular frame is provided on opposite sides with ears with holes with a diameter of 7 mm for attaching the registration number to the bumper of the car, and the location of the holes of the ears exactly coincides with the fixing points for mounting the registration number provided by the vehicle manufacturer using standard fixing materials.

As the experiments showed, due to the aforementioned design features of the car bumper protective device and the physicomechanical properties of non-metallic elastic materials used for its manufacture, when a car collides at low speeds (5-15 km / h) with an obstacle, an effective damping of the resulting dynamic load occurs. Moreover, this is facilitated not only by the high strength and elasticity of the rubber-cord material, but also by the design of the device itself.

In particular, in the event of a collision with an obstacle, the frontal lateral end parts of the protective device having a spring resemblance are first perceived by the dynamic load, and only then the other elements of the device perceive the shock load. As a result, a kind of redistribution of the dynamic load from the lateral ends to the rest of the protective device occurs. This, in turn, leads to a mitigation of the shock load and, as a result, to the effective protection of the car bumper from mechanical damage.

The inventive design solution is illustrated by figures, where:

FIG. 1 - Design of a protective device, front view;

FIG. 2 - The design of the protective device, 3/4 side view;

FIG. 3 Scheme of fastening on the bumper of the car protective device

The design of the protective device for the front bumper of the car consists of a hollow rectangular frame open inward, the opposite long sides of which (Fig. 1, position 1) are made from the front side concave inward (Fig. 2, position 2), and with the back adjacent to the bumper of the car sides, rectilinear and flat (Fig. 2, position 3). As a result of this design, the lateral short sides (Fig. 1, position 4) of the protective device exceed its long sides in thickness (Fig. 1, position 1), as a result of which the protective device resembles a design of two springs, gradually thickening from the middle part (Fig. .2, position 5) to their end part (Fig. 2, position 6) and resting on these opposite end parts on the opposite thickened short sides (Fig. 1 and 2, position 4) of the described device.

In addition, the protective device is equipped on the back with a seat socket for installing registration number 7 (Fig. 3) of the car, as well as two ears 8 (Fig. 1) with holes 9 with a diameter of 7 mm (Fig. 1) for fastening with fixing materials 2 (Fig. 3) registration number 3 (Fig. 3) and the protective device to the bumper 11 (Fig. 3) of the car, and the location of the holes of the ears 8 exactly coincides with the mounting points provided by the vehicle manufacturer for mounting registration number 7 (Fig. 3). 3) using standard fasteners 10 (Fig. 3).

As a material for the manufacture of a protective device for the front bumper of a car, it is recommended to use non-metallic elastic plastic material, such as rubber-cord material, which has such useful characteristics, including high tensile strength, effective compensation properties, the ability to effectively absorb dynamic loads and high damping ability, then there is the ability to convert energy into heat during sudden deformations due to shock loads Dynamic collision with an obstacle.

The fastening of the proposed device to the bumper of the car is carried out in the following sequence. First, the registration number 7 of the car is inserted into the landing socket on the back flat side of the protective device, then the fastening materials are threaded through the holes 9 of the side ears 8 and the registration number 7 is fastened together with the protective device to the bumper 11 of the car. Due to this fastening, the protective device reliably and tightly adjoins the rear flat surface 3 to the bumper of the car.

The device operates as follows:

At the moment of collision of the bumper protective device at low speed (5-15 km / h) on the obstacle, the initial dynamic load falls on its lateral short thickened sides 4 of the protective device with its subsequent redistribution to the remaining elastic elements of the device. According to the experiments performed, the loads resulting from such a dynamic impact are effectively damped due to the elastic properties of the rubber-cord material.

In addition, the shape of the protective device resembling a design of two springs, gradually thickening from the middle part 5 of the long sides 1 to their end part 6 and resting on these opposite thickened short sides 4 of the described device gradually matters. Thanks to this design, the protective device works to some extent approximately the same as a conventional sheet metal spring. In particular, at the moment of impact, it bends like an elastic beam, which additionally helps to extinguish the energy of the impact in a collision with obstacles.

In particular, it was established by observations that in a series of 150 shock loads at a vehicle speed of 12 km / h, the proposed protective device for the car bumper practically remained in the same state as before the experiments.

Among the undoubted advantages of the proposed device - low cost, reliability and simplicity of design. In the process of impact, as noted by observations, the proposed protective device for the front bumper of the car responds not only to frontal loads, but also to lateral ones that occur when the car collides with an obstacle, for example, during a turn. As established by experiments, the maximum deformation during a central impact at a vehicle speed of 14 km / h is 15.9 mm, at an angular impact of 22.9 mm, which does not negatively affect the operational characteristics of the described device.
