Definitions
- Vehicle comprising a device for retaining the spare wheel
- the present invention relates to a vehicle comprising a spare wheel retaining device.
- a spare wheel is housed in a recess in the rear boot floor of a vehicle.
- this spare wheel is completely included in the recess, so that during an accidental rear impact of the vehicle against an external obstacle, said wheel remains housed in this recess, without risk of coming out and constituting a projectile. likely to impact the back of an occupant who is seated in the rear of the vehicle.
- a vehicle according to the invention is a hybrid vehicle having an electric battery under the floor of the rear boot and a spare wheel housed in said boot, said vehicle being configured to prevent the spare wheel from being thrown front in the event of a rear impact of said vehicle against an external obstacle.
- X is a longitudinal front-rear axis of the vehicle directed towards the rear
- Y is a transverse axis directed towards the right of the vehicle
- Z is a vertical axis directed upwards.
- the invention relates to a hybrid vehicle having a rear trunk delimited by a rear floor, and an electric battery fixed under said rear floor, said vehicle further comprising a spare wheel resting on said rear floor and emerging from that -this.
- the vehicle comprises a spare wheel retaining stop fixed to the rear floor between said spare wheel and a rear row of seats, said retaining stop having the function of preventing the spare wheel to move towards the rear row of seats in the event of a rear impact of said vehicle against an external obstacle.
- the spare wheel may turn into a dangerous projectile liable to impact the back of an occupant who is seated on the rear row of seats, and seriously injure him.
- This retaining stop is securely fastened to the rear floor of the trunk, so as not to be moved in the event of an accidental impact of the vehicle against an external obstacle. Indeed, since its purpose is to stop the travel of the spare wheel during such an impact, it must not itself be able to form a projectile by moving.
- this retaining abutment is designed not to deform during this impact, in order to avoid the situation in which it would no longer be able to retain the spare wheel. It is assumed that the stowage of the electric battery under the rear floor of the rear boot caused the said rear floor to rise, placing the spare wheel in the category of sources of potential danger for the occupants of the rear row during a rear impact of the vehicle.
- the expression "rear row of seats” is a generic expression designating the row of seats located just in front of the rear boot. If the vehicle has only one row of seats comprising a driver's seat and a passenger seat, the expression “rear row of seats” may designate this single row of seats. Likewise, this expression can also refer to a rear seat.
- the spare wheel has an axis of revolution and that, when it rests on the rear floor, this axis of revolution extends perpendicularly to said floor.
- the wheel is inscribed in a plane, and that, when it rests on the rear floor, said plane is parallel to said floor.
- the height of the retaining stop is greater than or equal to the height of the spare wheel emerging from the rear floor.
- the height of the wheel corresponds to the width of a tire of said wheel.
- the dimension of the retaining stop considered along a transverse axis Y of the vehicle is greater than or equal to a diameter of the spare wheel. In the same way, it must also be prevented that the spare wheel cannot escape on the sides of the retaining stop.
- the retaining stop has an inclined part extending from a zone of the rear floor located in front of the spare wheel towards an upper front zone of the spare wheel. In the event of a vehicle impact, this inclined part will stop the forward travel of the spare wheel, tending to lower it towards the rear floor of the boot.
- the dimension of the inclined part of the retaining stop considered along a transverse axis Y of the vehicle is greater than or equal to a diameter of the spare wheel.
- the inclined part of the retaining abutment has several tubular segments arranged in a latticework.
- the retaining abutment has increased mechanical strength, giving it a character of great robustness and non-deformability.
- Such a stop will effectively block any forward travel of the spare wheel during a vehicle impact, while not deforming.
- such a perforated retaining stop will contribute to lightening the vehicle.
- the retaining abutment has a fixing wall located in front of the inclined part and in continuity with the latter, said fixing wall being oriented with respect to the inclined part so that it establishes surface contact with a surface of the rear floor. This fixing wall will define an interface plane with a surface of the rear floor, improving the conditions of contact between the retaining abutment and the rear floor of the rear trunk.
- the fixing wall extends along a transverse axis Y of the vehicle and has a plurality of holes through which screws pass to ensure the fixing of the retaining stop to the rear floor .
- This method of attachment is particularly but not exclusively suitable for a vehicle according to the invention. Fixing by welding can also be envisaged if the materials of the retaining abutment and of the floor are compatible for such a weld.
- the retaining abutment is metallic.
- the retaining stop comprises a rigid wire forming a loop and covering the spare wheel, said wire having the function of stabilizing the position of the spare wheel on the rear floor during routine use of said vehicle.
- This rigid wire helps to stabilize the position of the spare wheel in the rear boot of the vehicle, during normal vehicle driving, but plays no particular role in the event of an accidental impact of the vehicle against an external obstacle.
- this wire must be raised manually to be able to remove the spare wheel from the rear boot.
- a vehicle according to the invention has the advantage of having a spare wheel as well as an electric battery placed under the rear floor of the rear trunk, respecting the safety of the passengers thanks to a judicious installation of a spare wheel retaining stop.
- the spare wheel no longer represents a danger for the occupants of the vehicle in the event of an accidental impact of the vehicle against an external obstacle.
- It also has the advantage of having a retaining abutment having a geometry optimized, to allow said stopper to effectively retain the spare wheel, while being light.
- FIG. 1 represents a perspective view of a rear trunk of a vehicle according to the invention
- FIG. 2 shows a perspective view from another angle of the trunk of Figure 1
- FIG. 3 shows a top view of the rear trunk of Figures 1 and 2,
- FIG. 4 shows a side view of an area of the rear trunk of Figures 1, 2 and 3,
- FIG. 5 shows a perspective view of a vehicle retaining stop according to the invention
- a vehicle 1 according to the invention comprises a rear trunk 2 placed just behind a rear row 3 of seats, comprising for example three seats 4, 5, 6.
- This trunk 2 is delimited by a rear floor 7 extending in a horizontal plane when the vehicle 1 itself rests on horizontal ground.
- a vehicle 1 according to the invention is a hybrid vehicle comprising an electric battery 8 which can for example be a 200V battery.
- This electric battery 8 having to be placed under the rear floor 7 of the rear trunk 2, it was necessary to raise said rear floor 7 and thus bring it above two side members of said vehicle 1 .
- a vehicle 1 according to the invention also has a spare wheel 9, which is housed in the rear trunk 2. But due to the presence of the electric battery 8 under the floor rear 7, it is no longer possible to house this spare wheel 9 in a recess of said rear floor 7.
- the spare wheel 9 is then fixed to the raised rear floor 7, without being placed in a recess of said rear floor 7. Under these conditions, in the event of a rear impact of the vehicle 1 against an external obstacle, the spare wheel 9 risks detaching from the rear floor 7, and to then be thrown forward in the direction of the back of an occupant who would be seated on a seat 4, 5, 6 of row 3 behind. This spare wheel 9 would then become comparable to a projectile, liable to cause serious injury to said occupant.
- this spare wheel 9 has an axis of revolution. It is then placed in the rear trunk 2, so that said axis of revolution extends perpendicularly to the rear floor 7. In other words, it can be assumed that the spare wheel 9 is inscribed in a plane, and the spare wheel 9 is placed in the trunk 2 so that said plane is parallel to said floor 7.
- a vehicle 1 In order to prevent this spare wheel 9 from being suddenly thrown forward in the event of a rear impact of the vehicle against an external obstacle, a vehicle 1 according to the invention implements a retaining stop 10 intended to block said spare wheel 9 in order to prevent it from impacting the back of an occupant.
- this retaining stop 10 comprises a front part 11, intended to be placed in front of the spare wheel 9 between said spare wheel 9 and the rear row 3 of seats 4, 5, 6, and a rear part 12, intended to cover the spare wheel 9.
- the front part 11 has a central zone 13 considered along a transverse axis Y of the vehicle 1, which is composed of several tubular segments 14 arranged in a trellis. These segments 14 are part of the same plane, which is inclined with respect to the rear floor 7. Indeed, this plane originates in a zone of the rear floor 7 located at the front of the spare wheel 9, and extends straight to an upper front area of said spare wheel 9.
- the front part 11 comprises a fixing wall 30 located in front of the inclined central zone 13 and in continuity therewith.
- This fixing wall 30, which comprises a central segment 15 bordered by two inclined lateral segments 16, 17, is oriented with respect to the inclined central zone 13 such that it establishes surface contact with a surface of the rear floor 7.
- this fixing wall 30 also extends in a horizontal plane, so that the central segment 15 is parallel to a transverse axis Y of the vehicle while being located in front of the inclined central zone 13.
- This fixing wall 30 has several orifices each intended to receive a screw to secure the retaining stop 10 to the rear floor 7 of the rear boot 2.
- the retaining abutment 10 comprises a profiled rear segment 18, extending parallel to the central segment 15 of the fixing wall 30, said rear segment 18 joining two ends of the segments 16, 17 of said fixing wall 30, and delimiting an upper rear zone of the plane in which the tubular segments 14 of the central zone 13 of the front part 11 of the retaining abutment 10 are inscribed.
- the rear part 12 comprises a rigid wire 19 forming a loop originating at a point of the rear segment 18 and ending at another point of said rear segment 18.
- This wire 19 is pivotally mounted on the rear segment 18, at its two points of intersection with said rear segment.
- this wire 19 covers the spare wheel 9 and has a secondary loop 20 having dimensions compatible with those of a handle, said secondary loop 20 resting on a surface of the rear floor 7 of the rear trunk 2.
- This wire 19 covers the spare wheel 9 in order to stabilize the position of said spare wheel 9 in the rear trunk 2, during a normal driving phase of the vehicle 1 .
- the driver wishing to use the spare wheel 9 will grab the secondary loop 20 of the wire 19, then will exert an effort upwards so as to make said wire 19 pivot around the rear segment 18.
- the spare wheel 9 is then disengaged, and the driver can then grab hold of it in order to mount it on the vehicle in place of the defective wheel.
- the retaining stop 10 comprising the front part 11 and the rear part 12 is preferably made of metal.
- the retaining abutment 10 has a high mechanical strength, in particular due to the presence of the tubular segments 14, and is supposed not to deform when the occurrence of such a shock.
- the anchoring points of the retaining stop 10 in the rear floor 7 are strong enough to prevent said retaining stop 10 from moving in the event of such a rear impact.
