Description

Title of the invention: Bumper frame for motor vehicle

[0001] The technical context of the present invention is that of devices associated with structural elements equipping the front of a motor vehicle that secure said motor vehicle in the event of accidents or other traffic incidents. More particularly, the invention relates to a bumper frame for a motor vehicle.

[0002] In the prior art, a standard front-end design requires the integration of technical elements. Specifically, these technical elements manage rainwater runoff from the front of the vehicle and, in particular, prevent water from entering areas behind the bumper containing electrical components or interfaces, such as the engine compartment. This precaution reduces the electrical risks associated with the presence of water. Examples of commonly used techniques include ramps and drainage outlets arranged in a cascade, and a component incline that allows water to drain naturally.

[0003] The drawback of these design standards is that they are unsuitable for certain geometries of parts exposed to water on the front end. These design standards are unsuitable for certain particularly problematic areas where natural water flow management is insufficient. Furthermore, these design standards include a multiplication of water drainage paths, which complicates the arrangement of structural elements equipping the front of a motor vehicle.

[0004] The present invention aims to provide a new bumper frame for motor vehicles in order to address at least largely the previous problems and to lead to other advantages.

[0005] Another object of the invention is to propose a new bumper frame for motor vehicles that is reliable in its operation, and as a frame.

[0006] Another object of the invention is to propose a new bumper frame for motor vehicles that is simple, both from the point of view of its implementation and from the point of view of its manufacture.

[0007] Another object of the invention is to propose a new bumper frame for motor vehicles that ensures water drainage from the front of the motor vehicle.

[0014] According to the invention, the base includes at least one element for collecting rainwater running off the bumper frame. In the bumper frame according to the first aspect of the invention, at least one collection element is intended to collect rainwater running off the bumper frame. Each collection element is configured to be able to collect and temporarily store rainwater running off the bumper skin.

[0015] It is understood that, when fitted to a motor vehicle, the bumper frame conforming to the first aspect of the invention allows for "water management". In other words, the bumper frame conforming to the first aspect of the invention, in the motor vehicle it equips, forms a rainwater management element by collecting said rainwater. The "water management" implemented at the level of the bumper frame conforming to the first aspect of the invention is strictly implemented at the level of at least one collection element.

[0016] The invention, according to its first aspect, advantageously consists of providing a single temporary rainwater retention system. The "water management" enabled by the bumper frame, according to the first aspect of the invention, through its at least one collection element, simplifies rainwater management at the front of the motor vehicle equipped with the invention without loss of efficiency.

[0017] The bumper frame according to the first aspect of the invention advantageously comprises at least one of the improvements below, the technical characteristics forming these improvements being able to be taken alone or in combination:

[0018] - at least one collection element has a water drainage hole rainwater collected. In this configuration, the invention, according to its first aspect, advantageously consists in providing that at least one collection element forms a single system allowing both temporary retention of rainwater and its drainage. The rainwater drainage hole allows the rainwater collected in at least one collection element to be evacuated. This drainage through the rainwater drainage hole is made possible by simple gravity;

[0019] - at least one collection element takes the form of a reservoir formed directly in the bumper frame. By reservoir, we mean that the collection element takes the form of a temporary rainwater collector, configured to collect rainwater that may temporarily accumulate there;

[0020] - the reservoir forming each at least one collection element has a shape rectangular. Such a tank is simple to maintain and functional;

[0021] - at least one collection element takes the form of a reservoir of the shape rectangular formed directly within the bumper frame. It is understood that at least one collection element is provided within the material forming the bumper frame. By being formed directly within the bumper frame, this at least one collection element allows for a material saving within the bumper frame, in accordance with the first aspect of the invention;

[0022] - a bottom wall of the tank forming at least one collection element is inclined along a larger dimension of said reservoir, so as to allow gravity flow of the rainwater collected in said reservoir. It is understood that the bottom wall of the reservoir is inclined so as to form an angle with respect to a plane, in particular that of the horizon. Thus, such a bottom wall allows the collected rainwater to flow towards a low point on the bottom wall of the reservoir;

[0023] - the reservoir forming each at least one collection element has a hole drainage of collected rainwater. The drainage hole allows for drainage rainwater is collected in at least one collection element. In at least one collection element, the drain hole allows the rainwater stored in the tank to be evacuated;

[0024] - a bottom wall of the tank forming at least one collection element is inclined along a larger dimension of said tank, so as to allow gravity flow of the rainwater collected in said tank, the tank having a drain hole for the collected rainwater. It is understood that the bottom wall of the tank is inclined so as to form an angle with respect to a plane, in particular the horizon. Thus, such a bottom wall allows the collected rainwater to flow towards a low point on the bottom wall of the tank. The drain hole allows the collected rainwater to be discharged into at least one collection element. In at least one collection element, the drain hole allows the rainwater stored in the tank to be discharged. Advantageously, in at least one collection element, the drain hole allows the rainwater stored in the tank to be discharged and flowed towards a low point on the bottom wall of the tank;

[0025] - the drain hole is located at one lower end of the tank forming at least one collection element, relative to an inclination of the bottom wall. It is understood that, in the bumper frame according to the invention, the drainage hole thus located promotes a gravity flow of rainwater collected in said tank out of the tank;

[0026] - the drain hole is located at one end of the reservoir forming each at least one collection element, relative to a proper elongation axis of said reservoir corresponding to its largest dimension;

[0027] - the drain hole of each tank forming at least one collection element is intended to be located behind a front headlight of the motor vehicle. In this configuration and in the motor vehicle equipped with the invention, the drain hole of each tank allows the rainwater collected in each at least one collection element to flow into an area of ​​the motor vehicle devoid of electrical components or interfaces. Thus, such a configuration reduces the electrical risks inherent in the presence of water in this area;

[0028] - a capacity of each tank forming at least one collection element is between 200 cm3 and 1000 cm3. Such a capacity allows for the storage of a significant quantity of rainwater running off the bumper frame without the risk of saturating each reservoir, while remaining consistent with the volume of the bumper frame according to the invention;

[0029] - a length of the reservoir forming each at least one collection element, taken along an axis of proper elongation of said reservoir corresponding to its greatest dimension, is between 25 cm and 35 cm. Preferably, a length of the reservoir forming each at least one collection element, taken along an axis of proper elongation of said reservoir corresponding to its largest dimension, is equal to 30 cm;

[0030] - a width of the reservoir forming each at least one collection element, taken along an axis perpendicular to the axis of elongation of said tank, is between 1 cm and 3 cm. Preferably, a width of the tank forming each at least one collection element, taken along an axis perpendicular to the axis of elongation of said tank, is equal to 2 cm;

[0031] - a depth of the reservoir forming each at least one collecting element is less than 15 mm;

[0032] - a depth of the reservoir forming each at least one collection element varies progressively along a proper elongation axis of the reservoir corresponding to its largest dimension, so as to be between 8 mm and 10 mm along said proper elongation axis;

[0033] - a rear edge of each at least one collecting element takes the form of a water retention wall that projects beyond the reservoir and along its natural elongation axis. The water retention wall prevents water from flowing across it. In the motor vehicle equipped with the invention, the rear edge of each at least one collection element forms a mechanical water retention barrier between the front edge and the engine compartment of the motor vehicle;

[0034] - the rear edge extends in a straight line, the rear edge forming a wall flat. By flat wall, we mean that the rear edge forms a flat wall, without curvature. Such a wall facilitates the flow of rainwater and prevents any retention. The flat wall forms a drainage plane for rainwater running off the bumper frame, the drainage plane formed by the rear edge of each collection element extending along a plane formed by a transverse axis and a vertical axis of the bumper frame;

[0035] - each at least one collecting element has a front edge extending along of the axis of proper elongation and taking the form of an inclined wall which allows water to flow towards at least one corresponding collection element. The front edge of each at least one collection element is intended to promote the collection of runoff rainwater by the at least one collection element;

[0036] - the bumper frame conforming to the first aspect of the invention comprises a a first collection element located on one lateral side of said bumper frame and a second collection element located on a second lateral side of the bumper frame. In the bumper frame, the first collection element and the second collection element are located on opposite lateral sides. Thus, the first lateral side and the second lateral side of the bumper frame conforming to the first aspect of the invention each have at least one collection element. Such a configuration makes it possible to collect rainwater running off the first lateral side and the second lateral side of the bumper frame;

[0037] - the first collection element and the second collection element extend according to an axis of proper elongation oriented along a transverse axis of the bumper frame. In such a configuration, the first collection element and the second collection element allow the collection of rainwater running off at several points of the bumper frame;

[0038] - the first collecting element and the second collecting element are arranged and oriented symmetrically with respect to a median longitudinal axis of the bumper frame;

[0039] - the rear edge of the collection elements extends between the first collection element and the second collection element, at the level of a median area of ​​the bumper frame;

[0040] - the two collection elements extend along a transverse axis of the compartment engine ;

[0041] - relative to the transverse axis, the two collection elements are located on either side and, on the other hand, a depression in the bumper frame, the depression creating a gap between the hood of the motor vehicle and the bumper frame to allow for localized deformation of the hood in the event of a collision with a pedestrian. The depression in the bumper frame forms an area of ​​reduced mechanical resistance in the bumper frame according to the invention. This area of ​​reduced mechanical resistance in the bumper frame according to the invention facilitates localized deformation of the bumper frame at the level of said depression. By allowing localized deformation in the event of a collision with a pedestrian, the bumper frame enhances the safety of the motor vehicle it equips.

[0042] According to a second aspect of the invention, a motor vehicle is proposed comprising: (i) an engine compartment; (ii) a bumper frame conforming to the first aspect of the invention or to any of its improvements, the bumper frame being fixed securely to the engine compartment; (iii) a bumper and a bumper skin fixed securely to the bumper frame.
