Description

Title of the invention: MOTOR VEHICLE COMPRISING A CHARGING CABLE STORAGE SYSTEM WITH A MEANS OF HOLDING A GRIP

[0001] The invention relates to the field of systems and devices for storing charging cables for motor vehicles with rechargeable traction batteries.

[0002] Charging cables are generally stored in a cable housing provided for this purpose. In some cases, the housing has a small width in the horizontal direction of the vehicle.

[0003] In the prior art, storage systems have been proposed with two fixed, spaced-apart structures, around which the charging cable is wound.

[0004] Unfortunately, the cable has a loose arrangement and is prone to detachment from these structures, which is inconvenient. In addition, the plug is generally free in the housing and prone to impact on walls of the cable housing.

[0005] Furthermore, in the case of a housing with a small width, the edges of the housing hinder the handling of the cable to be wound around the winding structures. The handling to have sufficient tension of the charging cable proves tedious.

[0006] An objective of the present invention is to remedy the defects of the prior art, and in particular to propose a practical charging cable storage solution involving simple and rapid handling for proper maintenance of the cable and the plug.

[0007] To achieve this objective, the invention proposes a motor vehicle comprising a rechargeable traction battery, a housing and a system for storing a charging cable in the housing, the storage system having a reference in space comprising a longitudinal axis along a rolling direction of the motor vehicle; a lateral axis perpendicular to the longitudinal axis, defining a direction external to the housing and an internal direction towards the housing, and a vertical axis perpendicular to the longitudinal axis and to the lateral axis, the storage system comprising: - an upper winding support; - a lower winding support arranged below the upper winding support at least along the vertical axis; and - a grip holding means arranged between the upper winding support and the lower winding support at least along the vertical axis, the grip holding means being configured to hold a grip of the charging cable in fixed position in the housing.

[0008] Advantageously, the invention makes it possible to have a cable and a socket stored and immobilized, and to avoid impacts of the cable or the socket on the walls of the housing.

[0009] According to one variant, the holding means comprises a holding hook configured to receive the socket such that the socket rests on the holding hook.

[0010] This provides a support for installing the socket to immobilize the socket in the housing.

[0011] According to a variant, the holding means comprises a clamp configured to receive the plug and parts of the wound cable, in a pincer fashion.

[0012] This makes it possible to reinforce the immobilization of the socket and also to immobilize the charging cable.

[0013] According to a variant, the lower winding support is mounted to move in translation at least upwards and downwards with reference to the vertical axis.

[0014] This allows tension to be applied to the cable to improve the immobilization of the cable, and the tension to be released to remove the cable.

[0015] According to a variant, the lower winding support and the upper winding support are movable in translation at least laterally towards the outside and the inside of the housing with reference to the lateral axis.

[0016] This allows the winding supports to be removed from the housing so as to wind the cable without taking up space in the housing.

[0017] According to a variant, the holding means is mounted to move in translation at least upwards and downwards with reference to the vertical axis.

[0018] This makes it possible to adapt the position of the holding means for different winding and tension configurations resulting in higher or lower positions of the socket.

[0019] According to a variant, the motor vehicle comprises a charging cable wound on the upper winding structure and the lower winding structure, the cable being equipped with a socket held by the holding means.

[0020] This allows the vehicle's traction battery to be recharged.

[0021] According to a variant, the motor vehicle comprises a manual control means for controlling the translational movements of the lower winding support and / or the upper winding support.

[0022] This allows for movement control without the expenditure of electrical energy.

[0023] According to one variant, the manual control means comprises at least one return means.

[0024] This allows for projections of structures without using electrical energy.

[0025] According to a variant, the motor vehicle comprises a motorized control means for controlling the translational movements of the winding support. lower and / or upper winding support.

[0026] This allows for automatic and large-scale movement control.

[0027] The invention will be further detailed by the description of non-limiting embodiments, and on the basis of the appended figures illustrating variants of the invention, in which: - [Fig.l] schematically illustrates a front view of a charging cable storage system according to a first embodiment of the invention, where the lower winding support is in two operating positions; - [Fig.2] schematically illustrates a front view of a charging cable storage system according to a second embodiment; - [Fig.3] schematically illustrates a top view of a pincer holding means of the cable storage system of [Fig.2], where the holding means is in two operating positions; - [Fig.4] schematically illustrates a side view of the cable storage system of [Fig.2], where the winding supports are in two operating positions.

[0028] The invention relates to a cable storage device in an electric vehicle.

[0029] The storage system of the invention has a reference in space comprising a longitudinal axis X along a rolling direction of the motor vehicle; a lateral axis Y perpendicular to the longitudinal axis X, and a vertical axis Z perpendicular to the longitudinal axis X and to the lateral axis Y.

[0030] It can be considered that the lateral axis Y defines a direction external to the housing L towards the reader of [Fig.l]; and an internal direction towards the housing, oriented towards the inside of the plane of the board.

[0031] The invention relates more particularly to housings which are narrow in width along the longitudinal axis X, which involve discomfort for the user on the front and rear edges of the housing L, making handling difficult. The width of the housing L along the X axis is approximately 15 to 20 cm.

[0032] The invention proposes a hooking of the socket P at the end of the cable C on a holding means M1, M2.

[0033] In the first embodiment illustrated in [Fig.l], the holding means is a hook Ml on which the socket P rests.

[0034] In order to simplify handling and to have a correct positioning of the cable C in its housing L, it is proposed to have an upper winding support ES fixed in the upper part of the housing L, a lower winding support El movable in the lower part of the housing L, and the hook Ml to accommodate the socket P. The supports ES, El can be aligned along the vertical axis Z. The hook Ml is arranged between the supports ES, El at least along the vertical axis Z. We can consider a hook Ml offset along the longitudinal axis X or the lateral axis Z, relative to the alignment of the supports ES, El.

[0035] The movable lower winding support El makes it possible, in the high position, to facilitate the winding of the cable C, and the attachment of the socket P to its hook ML.

[0036] Furthermore, the movable lower winding support El allows, in the low position, the cable C to be stretched until the correct stowed position is obtained by lowering this support EL

[0037] In the case of a configuration with two fixed winding supports ES, El, depending on the winding of the cable C, the tension may be insufficient. It may be difficult to hook the socket P due to insufficient length between the last winding of the cable C and the socket P.

[0038] Alternatively, it is possible to envisage a movable hook M1 and a preferably fixed lower winding support E1. This makes it possible to adjust the position of the hook M1 to receive the socket P at different winding configurations and tensions of the cable C.

[0039] By adding mobility to the lower winding support El, this allows the cable C to be wound without worrying too much about the tension until the socket P is placed on the hook ML

[0040] Once the cable C is in place, it is sufficient to lower the lower winding support El to put the cable C under tension.

[0041] The actuation of the lower winding support El or the hook Ml can be done by means of a manual control, for example coupled to a spring, or by means of a motorized control coupled to a motor.

[0042] In the second embodiment illustrated in Figures 2 to 4, the storage system makes it possible to place the cable C on winding supports ES, El (for example telescopic) moved laterally along the lateral axis Y outside the housing L, to wind the cable C, then to push the assembly inwards.

[0043] Thus, there is a gain of space outside the housing L to place the cable C without constraint of the edges of the housing L, with the appropriate tension and regularity. The winding support assembly ES, El and cable C (or winding module) is then inserted into the housing L, which can be closed by a cover CL

[0044] In this embodiment, the holding means is in the form of a clamp M2 located between two winding supports ES, El, for example halfway. The clamp M2 at halfway makes it possible to ensure tension in the cable C in order to facilitate the sliding of the module in its housing L, and to avoid parasitic noise in rolling linked to the impacts of the P socket on the walls of the L housing.
