Title of the invention: ELECTRIC OR HYBRID MOTOR VEHICLE COMPRISING A REFLECTOR HATCH FLEXIBLE LOADING

[0001] The invention relates to electric or hybrid motor vehicles, and more particularly to the recharging hatches of these vehicles.

[0002] Known from the prior art is a patent application US20230228130 which describes a system for assisting in opening a reloading flap, in particular in the event of blockage caused by frost, which also serves as a locking device in the closed position. The system comprises an opening and closing device comprising a flap, or a hatch, rotatably mounted on an articulated arm, as well as an actuator responsible for actuating the flap. The actuator comprises an electric motor comprising a screw, said screw making it possible to drive a gear. The actuator is connected to a rotating spindle which is associated with an actuator element. The actuator element is a key having an internal thread which interacts with the rotating spindle having an external thread. When the rotating spindle rotates, a combined translational and rotational movement is generated to close and move the flap. However, disadvantages remain.The invention described is an assistance system, not an automated system. The driver or another user of the vehicle must open and close the said shutter themselves. The invention described simply provides assistance. In addition, the frost is broken by opening the said shutter, which risks breaking the said shutter. Furthermore, this does not allow the said shutter to be cleaned in the presence of mud or dust, for example.

[0003] The objective of the present invention is to remedy these drawbacks and to prevent the said hatch from becoming blocked, in particular due to ice or mud.

[0004] To achieve this objective, the invention proposes an electric or hybrid motor vehicle comprising an electric motor, said vehicle comprising a front running gear and a rear running gear whose points of contact with the ground define a base plane defined by a first longitudinal direction corresponding to straight-line driving, by a second transverse direction orthogonal to the first longitudinal direction and a third vertical direction orthogonal to the first direction and to the second direction and is oriented away from the ground, said vehicle comprising a battery, a body and a housing comprising a recharging base for replenishing electrical energy to said battery, said housing being positioned under said body in the third direction, said housing comprising a hatch configured to close said housing and at least one guide configured to hold said hatch in said housing, said at least one guide comprising a heating electric wire configured to heat said at least one guide, said housing comprising at least a first pusher system and a second pusher system, the first pusher system and the second pusher system being configured to allow the movement of said hatch vertically in the third direction, said first pusher system and said second pusher system each being capable of having a compressed configuration in which said first pusher system and / or said second pusher system have a first length and a relaxed configuration in which said first pusher system and / or said second pusher system have a second length, the first length being less than the second length,said at least one first pusher system and said second pusher system comprise a return system configured to move said at least one first pusher system and said second pusher system from the relaxed configuration to the compressed configuration, remarkable in that said hatch is flexible, said hatch being capable of having three positions: , - a first position in which said hatch is positioned against said at least one guide in the third direction so that said housing is closed, said first pusher system and said second pusher system (6b) having the relaxed configuration; - a second position in which said hatch is bent, said first pusher system having the compressed configuration and said first pusher system having the relaxed configuration; - a third position in which said hatch is positioned at a predetermined distance from said at least one guide so that said housing is open, said first pusher system and said second pusher system having a compressed configuration.

[0005] Thanks to the invention, the hatch 3 presents less risk of being blocked by external elements, in particular by frost and mud.

[0006] Preferably, said at least one guide comprises a seal.

[0007] The seal prevents water from entering said housing 1 when said vehicle is moving.

[0008] Advantageously, said hatch is motorized.

[0009] This configuration allows the automatic change of position of said plate, without intervention from the driver.

[0010] Advantageously, the hatch comprises a water ejection system for cleaning said hatch.

[0011] This helps to reduce the presence of dust, debris or mud on said trapdoor.

[0012] Advantageously, said hatch comprises a hot air ventilation system.

[0013] The hot air removes the dust present on said hatch and allows, in cooperation with the heating electric wire, to melt the frost present on said hatch.

[0014] Preferably, said housing comprises a third pusher system and a fourth pusher system.

[0015] Thus, in the event of failure of one of the push systems, deformation of the hatch is still possible.

[0016] Advantageously, said at least one first pusher system and said second pusher system each comprise a spring.

[0017] A spring has a long service life. Furthermore, a spring cannot fail unlike an electric push system.

[0018] Preferably, said return system is a mechanical, electromechanical or electromagnetic system.

[0019] Preferably, said electric heating wire is powered by a low voltage 12V or 24V battery.

[0020] This avoids using the battery's electrical energy, which is thus conserved to power the electric motor. The vehicle's autonomy is thus improved.

[0021] Advantageously, said vehicle comprises a means for warning a driver and a computer configured to measure the force necessary for the passage of the hatch from the first position to the third position, said warning means being configured to activate when said force is greater than a predetermined threshold value.

[0022] This allows the driver to know that said hatch is blocked and to react accordingly, without having to move outside of said vehicle.

[0023] 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 hatch in a first position in a housing of an electric or hybrid motor vehicle according to an embodiment of the invention; - [Fig.2] schematically illustrates said hatch in a second position in said housing of the electric or hybrid motor vehicle; - [Fig.3] schematically illustrates said hatch in a third position in said housing of the electric or hybrid motor vehicle.

[0024] [Fig.l] schematically illustrates a hatch in a first position in a housing of an electric or hybrid motor vehicle. The vehicle comprises a front running gear and a rear running gear whose points ofcontact with the ground define a base plane XY defined by a first longitudinal direction X corresponding to straight-line driving, by a second transverse direction Y orthogonal to the first longitudinal direction X and a third vertical direction Z orthogonal to the first direction X and to the second direction Y and is oriented away from the ground The vehicle comprises a body, an electric motor and a battery. The battery stores and ensures the distribution of electrical energy to power said electric motor. In addition, said vehicle comprises a housing 1 positioned under said body in the third direction Z. The housing 1 comprises a recharging base for replenishing electrical energy to said battery. The recharging base is a receiver which is capable of interacting with a transmitter linked to a recharging terminal.The connection between said base and said transmitter is mechanical or electromagnetic. In the case of a mechanical connection, said transmitter is an electrical plug, usually connected to a charging cable which connects said electrical plug to said charging terminal. In the case of an electromagnetic connection, said transmitter is a transmitting base. Thus, recharging is done by electromagnetic induction. The housing 1 comprises said hatch 3 configured to close said housing 1 in order to protect said charging base and prevent the entry of water, mud, dust or unwanted debris, in particular when the vehicle is moving. In addition, said housing 1 comprises at least one guide 4. By way of example, said at least one guide 4 is a rail allowing said hatch 3 to be moved in the third direction Z.Preferably, said at least one guide 4 comprises a seal to prevent water infiltration into said housing 1 when said housing 1 is closed. In [Fig.l], and in the following figures, said housing 1 comprises two guides 4. In another embodiment, said housing 1 comprises only one guide 4 which is located around the entire periphery of the housing 1. The guides 4 each comprise an electric heating wire 5 configured to heat the corresponding guide 4. In this way, in the event of frost blocking said hatch 3, the electric heating wire 5 causes the partial or total melting of the frost so that said hatch 3 can be movable. Preferably, said electric heating wire 5 is supplied with electrical energy by a low voltage battery, for example a 12V or 24V battery.Advantageously, said hatch 3 also comprises a hot air ventilation system for melting the frost, in cooperation with said heating electric wire 5. In addition, sending air onto the hatch 3 makes it possible to remove the dust accumulating on said hatch 3. The housing 1 comprises at least a first pusher system 6a and a second pusher system 6b. The pusher system is a component making it possible to transmit a force, i.e. a “push” towards another component, in this case towards said hatch 3. Advantageously, said housing 1 comprises a third. pusher system and a fourth pusher system. The first pusher system 6a and the second pusher system 6b are configured to allow the vertical movement of said hatch 3 in the third direction Z. The first pusher system 6a and said second pusher system 6b are each capable of having a compressed configuration or a relaxed configuration. In the compressed configuration, said first pusher system 6a and / or said second pusher system 6b have a first length. In the relaxed configuration, said first pusher system 6a and / or said second pusher system 6b have a second length. The first length is less than the second length. The first pusher system 6a and the second pusher system 6b each comprise a return system 7 configured to move said at least one pusher system 6a and said second pusher system 6b from the relaxed configuration to the compressed configuration.Advantageously, said return system 7 is mechanical, electromechanical or electromagnetic. Preferably, said at least one first pusher system 6a and said second pusher system 6b each comprise a spring 8. The hatch 3 is flexible. Indeed, said hatch 3 is made of a malleable material which allows its mechanical deformation. Thus, said hatch 3 is capable of having three positions: a first position, a second position and a third position. The first position is the position in which said hatch 3 is positioned against said at least one guide 4, towards the bottom of said housing 1 in the third direction Z. Thus, said housing 1 is closed.The first pusher system 6a and the second pusher system 6b each having the relaxed configuration so that said first pusher system 6a and said second pusher system 6b exert a force in the third direction Z against said hatch 3 in order to hold it against said at least one guide 4. In [Fig.l], said hatch 3 is illustrated in the first position.

[0025] In [Fig. 2], said hatch 3 is illustrated in the second position. The first pusher system 6a has the compressed configuration while the second pusher system 6b has the relaxed configuration. This generates the exertion of an asymmetrical force on said hatch 3 in the third direction Z. Indeed, said second pusher system 6b pushes said hatch 3 towards said at least one guide 4 in the third direction Z. Due to its flexibility, said hatch 3 deforms as shown in [Fig. 2]. The hatch 3 is therefore bent. The deformation of said hatch 3 makes it possible to remove mud, dust or even debris. Furthermore, in the event of frost, the deformation of the hatch 3 makes it possible to break said ice formation to prevent said hatch 3 from being blocked and, consequently, the replenishment of electrical energy to said battery from being impossible.Preferably, said hatch 3 comprises a water ejection system for cleaning said hatch 3. Indeed, mud, for example, is likely to block said hatch 3 in the first. position when the mud is dry. It is therefore preferable to remove the mud by the said water ejection system.

[0026] The hatch 3 is shown in the third position in [Fig. 3]. The hatch 3 is positioned at a predetermined distance d from said at least one guide 4 so that said housing 1 is open. In the third position, said first pusher system 6a and said second pusher system 6b have the compressed configuration. Thus, no force is exerted on the hatch 3 in the third direction Z. The hatch 3 is therefore maintained in the third position. Advantageously, said hatch 3 is motorized. Thus, said hatch 3 is able to change position automatically, without intervention from a user of the vehicle. Preferably, said vehicle comprises a means for warning a driver and a computer configured to measure the force necessary for the passage of the hatch 3 from the first position to the third position. The warning means is configured to activate when said force is greater than a predetermined threshold value.Thus, if the force required to open said hatch 3 is greater than said predetermined threshold value, this means that the hatch 3 is at least partially blocked. The driver is then warned so that he can unlock said hatch 3 by activating the means previously described. Alternatively, said means previously described are activated automatically. By way of example, said warning means is an audible and / or visual warning means. It may be a specific noise emitted in the passenger compartment of the vehicle or a warning light which lights up on the dashboard of said vehicle.
