BACKGROUND
The technical context of the present description relates to motor vehicle trunk packing and in particular trunk bottom arrangements intended to support a removable carpet of a motor vehicle trunk. More particularly, a motor vehicle trunk bottom element is described.
In the prior art, motor vehicle trunk arrangements are known comprising a trunk bottom element forming a sub-carpet storage, closed by a closure cap. These trunk bottom arrangements are intended to support a removable carpet of a motor vehicle trunk. In other words, these trunk bottom arrangements are intended to form a vertical counter-support supporting the removable carpet of a motor vehicle trunk.
One drawback of these trunk bottom arrangements is that they lack a uniform slope guaranteeing an optimal vertical counter-support. Indeed, should the closure cap of the trunk bottom element be poorly oriented, the slope is then non-homogeneous. When the trunk bottom element and the closure cap form a vertical counter-support which is not optimal, the removable carpet of a motor vehicle trunk is then poorly positioned. This is detrimental to the volume of the trunk and disturbs the positioning of the objects accommodated in the trunk of the motor vehicle equipped with said trunk arrangement.
Moreover, motor vehicle trunk bottom arrangements are also known that have trunk bottom elements specifically configured according to the use that will be made thereof and according to the type of motor vehicle that they equip. The closure caps that are associated therewith are also specific. Motor vehicle trunk bottom elements are known that are designed to house a spare wheel of the “donut” type, which is smaller than the other wheels equipping the motor vehicle. Alternatively, motor vehicle trunk bottom elements are known that are designed to house a spare wheel of the “full-size” type, similar to the other wheels of the motor vehicle. Still alternatively, motor vehicle trunk bottom elements are known that are designed to house an audio system.
The drawback of these motor vehicle trunk bottom arrangements is that they require different types of trunk bottom elements, each adapted to the object that it is intended to house, and cooperating with a type of closure cap specific to the considered trunk bottom element. Also, these motor vehicle trunk bottom arrangements require as many assembly chains as variants, which multiplies the number of parts to be manufactured. Such motor vehicle trunk arrangements are economically disadvantageous.
SUMMARY
The devices described herein aim to provide a new motor vehicle trunk bottom element in order to address at least some of the preceding problems and to further lead to other advantages.
Another aim is to provide a motor vehicle trunk bottom element that is simple both in terms of implementation thereof, and in terms of manufacture thereof.
Another aim is to provide a motor vehicle trunk bottom element that is universal and configured to adapt to different motor vehicles.
Another aim is to provide a motor vehicle trunk bottom element configured to guarantee the support, under load, of a removable carpet of a motor vehicle trunk.
Another aim is to provide a motor vehicle trunk bottom element that is compatible with the operation of an audio system.
According to a first aspect, at least one of the aforementioned objectives is achieved with a motor vehicle trunk bottom element, the trunk bottom element including (i) an external frame delimiting laterally and longitudinally the trunk bottom element, the external frame having in a vertical direction an upper bearing surface intended to receive a trunk floor element, and (ii) a central opening delimited by a cylindrical wall, the central opening being configured to house therein a spare wheel of the motor vehicle, characterized in that the trunk bottom element includes an angular indexing member configured to enable angular indexing of a closure cap of the central opening, with respect to the vertical direction of the trunk bottom element.
In the trunk bottom element, the external frame delimits the trunk bottom element, laterally and longitudinally. In the trunk bottom element, a longitudinal direction should be understood as a direction intended to extend from the front to the rear in the motor vehicle equipped with said trunk bottom element. A lateral direction extends from the left to the right in the motor vehicle equipped with said trunk bottom element. In the trunk bottom element, the lateral direction extends substantially perpendicular to the longitudinal direction.
In the trunk bottom element, the vertical direction corresponds to a direction from the bottom to the top. It should be understood that the upper bearing surface of the external frame of the trunk bottom element is intended to be oriented upward of said trunk bottom element.
The external frame is a structural element of the trunk bottom element. The upper bearing surface of the external frame is intended to support a trunk floor element of the motor vehicle equipped with the trunk bottom element. The upper bearing surface of the external frame is configured to guarantee a load resistance of said trunk floor element. For example, the trunk floor element is a removable carpet of a motor vehicle trunk.
In the trunk bottom element, the central opening delimited by the cylindrical wall is substantially centered in the lateral direction and in the longitudinal direction with respect to the external frame of the trunk bottom element.
In the trunk bottom element, the cylindrical opening is intended to house a spare wheel of the motor vehicle that it equips. It should be understood that the cylindrical opening is adapted to house a spare wheel of the “donut” type, which is smaller than other wheels equipping the motor vehicle, or alternatively a spare wheel of the “full-size” type, which is similar to the other wheels of the motor vehicle. Such a trunk bottom element is standard for different types of spare wheels, which allows for scale savings in a manufacturing line of a motor vehicle equipped with such a trunk bottom element.
The angular indexing member is configured to enable angular indexing of a closure cap of the central opening, with respect to the vertical direction of the trunk bottom element. The angular indexing member is configured to authorize one single and unique angular configuration of assembly of the closure cap on the trunk bottom element. The indexing member is intended to cooperate with an angular indexing device of the closure cap by complementary shape engagement.
Thus, the angular indexing member is intended to guarantee a unique relative position between the trunk bottom element and the closure cap of the central opening. The angular indexing member indexing the trunk bottom element and the closure cap of the central opening with respect to each other also allows relative alignment of the two parts to be kept. A unique relative position between the trunk bottom element and the closure cap of the central opening is essential to uniformly support the trunk floor element.
Indeed, the trunk bottom element is configured to ensure a homogeneous slope and therefore an optimal vertical counter-support in the motor vehicle trunk that it equips. The entire upper bearing surface of the external frame of the trunk bottom element then supports the trunk floor element, thereby reinforcing its robustness. The user perceived quality is improved compared to existing trunk elements.
Thus, the described device in accordance with its first aspect advantageously allows a load resistance of the trunk floor element to be guaranteed. It also enables a user to facilitate the relative positioning of the closure cap with respect to the trunk bottom element by the stress imposed by the angular indexing member.
Advantageously, the motor vehicle trunk bottom element in accordance with the first aspect comprises at least one of the improvements hereinbelow; the technical features forming these improvements could be considered separately or in combination:
- the angular indexing member is located at the upper bearing surface of the external frame of the trunk bottom element;
- according to a first variant, the angular indexing member is in the form of a notch formed on the cylindrical wall. The notch forming the indexing member corresponds to a cutout of the cylindrical wall of the trunk bottom element in accordance with the first aspect. It is possible to generalize to a female portion formed on the cylindrical wall of the trunk bottom element, intended to cooperate by complementary shape engagement with a male portion formed on the closure cap. According to a second variant, alternative or complementary to the first alternative embodiment, the angular indexing member is the form of a groove formed on an internal face of the cylindrical wall. The groove forming the indexing member corresponds to a long and narrow hollow notch formed in the cylindrical wall of the trunk bottom element in accordance with the first aspect. According to a third variant, alternative or complementary to the first alternative embodiment and/or to the second alternative embodiment, the angular indexing member is the form of a rib formed on an internal face of the cylindrical wall. For example, the rib forming the indexing member is in the form of a cylindrical or prismatic support. It is possible to generalize to a male portion projecting from the trunk bottom element, intended to cooperate by complementary shape engagement with a female portion formed on the closure cap;
- at the angular indexing member, the cylindrical wall is located radially at a distance from the external frame, with respect to the vertical direction, so that the trunk bottom element includes a recess peripheral to the central opening delimited radially by the cylindrical wall and by the external frame. Such a peripheral recess allows the amount of material necessary for the manufacture of the trunk bottom element in accordance with the first aspect to be reduced. Advantageously, the peripheral recess allows small objects to be housed under the floor element. Advantageously, the cylindrical wall is entirely located radially at a distance from the external frame, with respect to the vertical direction, the peripheral recess extending all around the cylindrical wall;
- an upper end of the cylindrical wall is coplanar or substantially coplanar with the upper bearing surface. Preferably, the upper end of the cylindrical wall is coplanar with the upper bearing surface of the external frame, so as to form only one bearing surface. By being coplanar, the upper support surface of the external frame of the trunk bottom element and the upper end of the cylindrical wall of the trunk bottom element are intended to receive the trunk floor element;
- the trunk bottom element includes a housing intended to house an audio system, the housing being formed between a lower face of the trunk bottom element and the upper bearing surface, the housing being delimited in the vertical direction by a membrane. In the trunk bottom element in accordance with the first aspect, the lower face is located opposite to the upper bearing surface, with respect to the vertical direction. Such a trunk bottom element is configured to allow alternately an audio system to be housed or a spare wheel of the motor vehicle of the “donut” type or a spare wheel of the motor vehicle of the “full-size” type to be housed in the central opening. Such a trunk bottom element allows for a new economy of scale in a manufacturing line of a motor vehicle equipped with such a trunk bottom element;
- the housing is in the form of an opening passing through the trunk bottom element according to the lateral direction.
- in the vertical direction, the membrane is located in an intermediate position between the upper bearing surface and the lower face of the trunk bottom element. Such a membrane offers a resonance space to the audio system;
- in the vertical direction, the membrane is located at a height comprised between 30% and 70% of a height of the trunk bottom element considered in the vertical direction and at the level of the housing. Such a membrane allows the rigidity of the trunk bottom element to be improved. In particular, such a membrane allows the rigidity of the cylindrical wall of the trunk bottom element to be improved by conferring better radial strength on said cylindrical wall;
- in the longitudinal direction, the upper bearing surface forms a non-zero angle with respect to a horizontal plane. Horizontal plane should be understood to mean a plane extending from the front to the rear and perpendicular to a vertical direction extending from the bottom to the top;
- the trunk bottom element is made of a light material, such as for example a polystyrene or an expanded polystyrene;
- the trunk bottom element is preferably obtained by molding. This industrial forming method also allows a large number of identical trunk bottom element units to be obtained at a lower cost, by repeatedly using the same mold.
According to a second aspect, a trunk arrangement for a motor vehicle is proposed, the trunk arrangement including (i) a trunk bottom element in accordance with the first aspect or according to any one of its improvements, and (ii) a closure cap housed in the central opening of the trunk bottom element, the closure cap including an angular indexing device cooperating with the angular indexing member of the trunk bottom element by complementary shape cooperation.
In the trunk arrangement in accordance with the second aspect, the closure cap is intended to close the central opening of the trunk bottom element.
In the trunk arrangement in accordance with the second aspect, the indexing member of the trunk bottom element cooperates with the angular indexing device of the closure cap by complementary shape engagement. The indexing member of the trunk bottom element is fastened to the angular indexing device of the closure cap by complementary shape engagement between a male portion and a female portion. In a first embodiment, the indexing member of the trunk bottom element forms the male portion and the angular indexing device of the closure cap forms the female portion. In a second alternative embodiment of the first embodiment, the indexing member of the trunk bottom element forms the female portion and the angular indexing device of the closure cap forms the male portion.
Cooperation between the indexing member of the trunk bottom element and the angular indexing device of the closure cap guarantees a unique relative position between the trunk bottom element and the closure cap. A unique relative position between the trunk bottom element and the closure cap is essential to optimally support the trunk floor element.
Indeed, such a trunk arrangement ensures a homogeneous slope when the closure cap closes the central opening of the trunk bottom element. The trunk arrangement in accordance with the second aspect offers an optimal vertical counter-support in the motor vehicle trunk that it equips. The entire upper bearing surface of the external frame of the trunk bottom element then supports the trunk floor element, thereby reinforcing its robustness. The quality perceived by the user is improved compared to the trunk arrangements in accordance with the second aspect.
Thus, the described device in accordance with its second aspect advantageously allows a load resistance of the trunk arrangement to be guaranteed.
The trunk arrangement for a motor vehicle in accordance with the second aspect advantageously comprises at least one of the improvements hereinbelow; the technical features forming these improvements could be considered separately or in combination:
- the closure cap has a general cylindrical conformation with shape and dimension complementary to those of the central opening of the trunk bottom element, the angular indexing device including a prismatic support which projects radially with respect to the general cylindrical conformation. Such a closure cap allows the entire central opening of the trunk bottom element to be closed. The projecting prismatic support forms a male portion intended to cooperate with the indexing member of the trunk bottom element forming a complementary female portion. The prismatic support projects radially in a direction perpendicular with respect to a vertical direction of the closure cap, and radial with respect to the cylindrical/circular shape of the general conformation of the closure cap;
- when the angular indexing member of the trunk bottom element is in the form of a notch formed on the cylindrical wall, the prismatic support includes a groove configured to enable engagement of the notch of the trunk bottom element. The groove of the prismatic support of the angular indexing device of the closure cap, engaged in the notch of the trunk bottom element, reinforces the closure cap being held in a unique angular position with respect to the trunk bottom element.
According to a third aspect, a motor vehicle is proposed including a trunk arrangement in accordance with the second aspect or according to any one of its improvements.
In the motor vehicle in accordance with the third aspect, the closure cap of the trunk arrangement is intended to close the central opening of the trunk bottom element.
In the motor vehicle in accordance with the third aspect, the indexing member of the trunk bottom element cooperates with the angular indexing device of the closure cap of the trunk arrangement by complementary shape engagement. The indexing member of the trunk bottom element is fastened to the angular indexing device of the closure cap of the trunk arrangement by complementary shape engagement between a male portion and a female portion. In a first example embodiment, the indexing member of the trunk bottom element forms the male portion and the angular indexing device of the closure cap of the trunk arrangement forms the female portion. In a second alternative embodiment of the first embodiment, the indexing member of the trunk bottom element forms the female portion and the angular indexing device of the closure cap of the trunk arrangement forms the male portion.
In the motor vehicle in accordance with the third aspect, cooperation between the indexing member of the trunk bottom element and the angular indexing device of the closure cap of the trunk arrangement guarantees a unique relative position between the trunk bottom element and the closure cap. A unique relative position between the trunk bottom element and the closure cap is essential to optimally support a trunk floor element of the motor vehicle in accordance with the third aspect.
In the motor vehicle according to the third aspect, a homogeneous slope is formed when the closure cap of the trunk arrangement closes the central opening of the trunk bottom element. In the motor vehicle in accordance with the third aspect, the homogeneous slope thus formed offers an optimal vertical counter-support in the trunk of said motor vehicle. The entire upper bearing surface of the external frame of the trunk bottom element then supports the trunk floor element of the motor vehicle in accordance with the third aspect, thereby guaranteeing a load resistance of the trunk arrangement in the motor vehicle in accordance with the third aspect.
