Description

Technical Field

[0001] This invention claims priority to French application 2003753, filed on April 15, 2020, the contents of which (text, drawings and claims) are incorporated herein by reference.

[0002] The technical background of this invention is the technical background of structural elements equipped on motor vehicles, and more specifically, the technical background of wiring harnesses designed to protect the arrangement at the front of a motor vehicle. More specifically, the present invention relates to an upper crossbeam for a front assembly of a motor vehicle. Background Technology

[0003] In the prior art, motor vehicles equipped with airbags (also known as "airbags") are known. These airbags are designed to deploy after a collision at the front of the motor vehicle. Accelerometers associated with the airbags can detect the collision. These accelerometers can transmit control signals to the airbags to activate their deployment, absorbing the impact and protecting the occupants of the motor vehicle. So-called "front" airbags are installed in the front of the passenger compartment of the motor vehicle (particularly in the footwell area), thereby protecting occupants seated in the front of the vehicle. To provide protection in the event of a frontal collision, the accelerometers for the front airbags are housed behind the upper crossbeam of the front section of the motor vehicle. These accelerometers include a wiring harness that connects the accelerometers to the airbags.

[0004] The upper crossbeam of the front assembly of the motor vehicle includes an air inlet for supplying an intake system located on the rear surface of the upper crossbeam. The intake system supplies external air to a thermostatic circuit configured for thermostatically regulating the engine assembly of the motor vehicle.

[0005] A known drawback of the upper crossbeam of the front subframe is related to the size of the air intake system, which is located behind the upper crossbeam and forces the wiring harness of the accelerometer to be positioned in front of it. The wiring harness is housed between the front surface of the upper crossbeam and an anti-recirculation baffle covering it. This exposes the wiring harness to the risk of degradation after a frontal collision. More specifically, the wiring harness could be clamped, crushed, or even severed by the anti-recirculation baffle, which moves against the upper crossbeam after the collision. This could endanger front-seat occupants, as any damage to the wiring harness could affect the transmission of control signals to the airbag to deploy it. Summary of the Invention

[0006] The present invention aims to provide a new upper crossbeam for the front assembly of a motor vehicle, in order to address the above-mentioned problems to a large extent, and also brings other advantages.

[0007] Another object of the present invention is to provide an upper crossbeam for a front assembly of a motor vehicle, the upper crossbeam being compatible with the operation of a front acceleration sensor.

[0008] Another object of the present invention is to provide an upper crossbeam for a front assembly of a motor vehicle, the upper crossbeam being compatible with the operation of an airbag.

[0009] According to a first aspect of the invention, at least one of the above objectives is achieved by an upper crossbeam for a front assembly of a motor vehicle, the upper crossbeam comprising: (i) a longitudinally elongated prismatic member configured to extend between two lateral edges of the motor vehicle; and (ii) a perforated grille extending projectingly from the upper surface of the prismatic member, the perforated grille being laterally limited by a side deflector extending to the front surface of the prismatic member, characterized in that the front end of the side deflector includes a recess configured to receive a wiring harness of the motor vehicle.

[0010] The upper crossbeam conforming to the first aspect of the present invention is used to mount on the front assembly of a motor vehicle. The upper crossbeam conforming to the first aspect of the present invention is used to mount on the motor vehicle and is located behind the front bumper of the motor vehicle. The upper crossbeam conforming to the first aspect of the present invention extends laterally through the motor vehicle on which it is mounted. The front assembly of the motor vehicle is, for example, an engine assembly. In particular, the upper crossbeam conforming to the first aspect of the present invention is used to mount on the motor vehicle and is located in front of the engine assembly of the motor vehicle.

[0011] The front end of the side deflector is located at the front surface of the prismatic member. The front end of the side deflector and the front surface of the prismatic member are oriented toward the front of a motor vehicle equipped with an upper crossbeam conforming to the first aspect of the invention.

[0012] The perforated grille allows airflow to pass through it. In a motor vehicle equipped with the upper crossbeam, the airflow is external to the vehicle. The perforated grille is configured to cooperate with the vehicle's air intake system. The upper crossbeam is positioned within the vehicle in which it is mounted and in front of the air intake system.

[0013] The notch extends laterally through both sides of the side deflector. The notch is located in the front end of the side deflector to accommodate the vehicle's wiring harness, which advantageously triggers the deployment of an "airbag" type airbag. In other words, the wiring harness passes through the side deflector at the location of the notch.

[0014] For the anti-recirculation baffle used to cover the upper crossbeam conforming to the first aspect of the invention, the notch forms a spacer in the front end of the side deflector. The notch has a fixed spacing for the passage of the vehicle's wiring harness. The notch thus forms a reinforcement in the front end of the side deflector. This notch strengthens the front end of the side deflector to prevent damage to the vehicle's wiring harness housed within the notch.

[0015] The upper crossbeam conforming to the first aspect of the invention is to be covered by an anti-recirculation partition. The electrical harness is to be located in an intermediate position between the anti-recirculation partition and the perforated grid of the upper crossbeam conforming to the first aspect of the invention. In particular, the notch is to face the anti-recirculation partition.

[0016] Therefore, in the upper crossbeam conforming to the first aspect of the invention, the notch in the side deflector ensures the maintenance of the integrity of the wiring harness at the location of the side deflector. This upper crossbeam prevents compression of the vehicle's wiring harness between the side deflector and the anti-recirculation partition. Without the notch, such compression is caused by the relative proximity between the anti-recirculation partition and the side deflector, corresponding to clamping, crushing, and / or cutting of the wiring harness.

[0017] In the absence of the characteristic notch of the present invention, compression of the wire harness is caused by the relative proximity of the anti-recirculation baffle and the lateral deflector located on both sides of the wire harness. In particular, the front-to-back movement of the anti-recirculation baffle is effective when a collision occurs in front of the upper crossbeam conforming to the first aspect of the invention, which is covered by the anti-recirculation baffle.

[0018] Thus, according to a first aspect of the invention, the invention advantageously protects the wiring harness of a motor vehicle that is housed in a recess in the side deflector of the invention in the event of a forward collision.

[0019] The upper crossbeam conforming to the first aspect of the invention advantageously includes at least one of the following improvements, the technical features forming these improvements may be employed individually or in combination:

[0020] - A notch formed on the front end of the side guide vane is located above the upper surface of the prismatic member. This notch is used to accommodate the vehicle's wiring harness extending from the upper surface of the prismatic member;

[0021] According to a first embodiment, the notch is vertically defined only by a lower edge located on the side of the upper surface of the prismatic member, and the notch extends to the upper edge of the side guide plate. The front end of the side guide plate includes the lower edge and the notch. The front end of the side guide plate does not have an upper edge. According to a second embodiment, which is an alternative to the first embodiment and corresponds to a preferred embodiment of the invention, the notch is vertically defined by an upper edge and a lower edge located on the side of the upper edge of the side guide plate, and the lower edge located on the side of the upper surface of the prismatic member. The front end of the side guide plate includes a lower edge and an upper edge located on both sides of the notch. The notch is provided in the front end of the side guide plate such that the opening of the notch for the passage of the wire harness is defined by the upper edge of the upper edge of the side guide plate and the lower edge of the upper edge of the side guide plate. Advantageously, in the second embodiment, the notch formed on the front end of the side guide plate has a V-shaped or U-shaped profile. The V-shaped or U-shaped profile is obtained in the extended plane of the side guide vane;

[0022] - The depth of the notch is greater than the diameter of the wiring harness to be installed in the notch, taken from the front edge of the side guide plate and the rear edge of the notch. The front edge of the side guide plate vertically defines the notch. The front edge of the side guide plate includes the lower edge of the side guide plate. The rear edge of the notch forms the bottom of the notch. With this notch depth, when the wiring harness is installed in the notch, the wiring harness is strictly contained between the front edge of the side guide plate and the rear edge of the notch. When the wiring harness is installed in the notch and when the anti-recirculation baffle is placed on the upper crossbeam according to the invention, the wiring harness is protected from being crushed by the anti-recirculation baffle that moves against the front edge of the side guide plate.

[0023] The prismatic member includes a plurality of ribs located on its upper surface and in front of the perforated grille, the ribs being configured to hold the wire harness. The ribs are advantageously configured to hold the wire harness within an extension of the recess. For this purpose, the ribs are advantageously aligned with the recess in a transverse direction relative to the upper crossbeam conforming to the first aspect of the invention.

[0024] - The ribs are positioned low relative to the perforated grille. These ribs prevent the wiring harness from being positioned within the airflow. Thus, the airflow passing through the perforated grille is neither disturbed by the ribs nor by the wiring harness. Furthermore, positioning the wiring harness outside the airflow prevents it from being subjected to vibrations that could damage it and / or cause it to detach from the ribs and / or the notches.

[0025] The upper crossbeam is made of a metallic material. The metallic material thus includes metals or metal alloys. As a non-limiting example, the metallic material forming the upper crossbeam may include aluminum and / or steel;

[0026] -The upper crossbeam is made of a steel-type metal material;

[0027] The upper crossbeam is obtained by molding. This industrial forming method also enables the same large number of units to be obtained at a lower cost by reusing the same mold. The upper crossbeam is advantageously obtained by casting. This forming method of the upper crossbeam thereby limits the reprocessing steps of the part and simplifies the manufacturing process for producing the upper crossbeam according to the invention. This industrial forming method also enables the same large number of units to be obtained at a lower cost by reusing the same mold.

[0028] According to a second aspect of the invention, an arrangement for a motor vehicle is provided, the arrangement comprising: (i) an upper crossbeam conforming to the first aspect of the invention or to one of its modifications; (ii) a wiring harness located at the upper surface of a prismatic member of the upper crossbeam and passing through a notch formed in the side guide plate; and (iii) an anti-recirculation baffle covering the upper crossbeam such that the anti-recirculation baffle simultaneously abuts against the upper end of the perforated grille and the front surface of the prismatic member, the wiring harness being located in an intermediate position between the anti-recirculation baffle and the perforated grille.

[0029] The arrangement conforming to the second aspect of the invention is intended to be located in the motor vehicle in which it is equipped and in front of the air intake system.

[0030] In an arrangement conforming to a second aspect of the invention, a notch in the side deflector of the upper crossbeam forms a spacer in the front end of the side deflector, the spacer allowing the passage of the vehicle's wiring harness.

[0031] The wiring harness is located in the middle between the anti-recirculation partition and the perforated grid of the upper crossbeam. In particular, the notch faces the anti-recirculation partition.

[0032] The wiring harness, for example, can electrically connect sensors of the vehicle, which are housed between the upper crossbeam and an anti-recirculation partition covering the upper crossbeam. Advantageously, an arrangement conforming to the second aspect of the invention includes an acceleration sensor located at the rear surface of the prismatic member and electrically connected to the wiring harness.

[0033] In an arrangement conforming to the second aspect of the invention, the wiring harness passes through a notch located between the anti-recirculation baffle and the front end of the side deflector of the upper crossbeam. In the event of a collision in front of the upper crossbeam, the anti-recirculation baffle undergoes forward-backward movement and may move to abut the front edge of the side deflector of the upper crossbeam. Thus, the wiring harness of the accelerometer passes through the notch, preventing it from being clamped, crushed, and / or severed by the anti-recirculation baffle moving against the upper crossbeam after the collision. The arrangement conforming to the second aspect of the invention advantageously avoids interruption of message transmission to the airbag to deploy the airbag when the wiring harness is connected to the accelerometer.

[0034] The anti-recirculation baffle is used to direct at least one fluid in an arrangement conforming to the second aspect of the invention. The fluid is, for example, an airflow and / or a waterflow.

[0035] In a motor vehicle equipped with an arrangement conforming to the second aspect of the invention, the anti-recirculation baffle is used to direct airflow outside the motor vehicle toward the vehicle's air intake system.

[0036] The anti-recirculation baffle is used to discharge the integrated water flow toward the outside of the arrangement. In a motor vehicle equipped with an arrangement conforming to the second aspect of the invention, the anti-recirculation baffle prevents the water flow from entering the vehicle's air intake system.

[0037] According to a third aspect of the invention, a motor vehicle is provided, the motor vehicle including an engine block and an arrangement conforming to a second aspect of the invention, the engine block being ventilated by means of an air intake system connected to a perforated grille of the upper crossbeam.

[0038] The upper crossbeam is located behind the front bumper of the motor vehicle.

[0039] The arrangement is located in a motor vehicle conforming to the third aspect of the invention and in front of the air intake system.

[0040] The intake system is located in a motor vehicle conforming to a third aspect of the invention and in front of the engine block. The intake system supplies external air to a thermodynamic regulating circuit configured to thermally regulate the engine block of the motor vehicle.

[0041] The anti-recirculation baffle directs at least one fluid in a motor vehicle conforming to the third aspect of the invention. The fluid is, for example, an airflow and / or a waterflow.

[0042] In a motor vehicle conforming to a third aspect of the invention, the anti-recirculation baffle is used to direct airflow outside the motor vehicle toward the vehicle's air intake system to ventilate the vehicle's engine block.

[0043] In a motor vehicle conforming to a third aspect of the invention, the anti-recirculation baffle is used to discharge integrated water from the motor vehicle to the outside. The anti-recirculation baffle prevents the water from entering the intake system of the motor vehicle.
