Description of the implementation methods The different figures, as well as the elements within a single figure, are not necessarily represented at the same scale. Across all figures, identical elements bear the same numerical reference. The terminology used in this description should in no way be interpreted in a limiting or restrictive manner, simply because it is used in conjunction with a detailed description of certain embodiments of the invention. Figure 1 shows a view of a magnetic fastening system consisting essentially of a mounting base 200 and a retaining item 100. Figure 1 shows that the mounting base 200 is arranged as a retractable flap within a structure 300, such as a car center console support. By way of example only, the retaining item 100 is a cup holder, such as a cup holder. Other retaining items, such as lamps, are also provided for by the present invention. The retaining item 100 can be electrically connected to the mounting base 200, as illustrated in Figure 6, which will be described in more detail later. The structure 300 has a housing for the retractable flap 200. In the retracted position, the flap 200 is fully retracted into the housing. Figure 2 shows a perspective view of a magnetic fastening system according to the invention, where the fastening base is in a retracted state in which the removable hatch 200 is fully received into the housing. In one embodiment, the retracted hatch 200 has an upper surface forming part of the surface of the structure 300. The retaining element 100 is provided with a fastening interface 90 by which the element 100 can be mounted to the fastening base, which protrudes from the housing. In one embodiment, the fastening interface 90 comprises a recess 80 and engagement means 62. Preferably, the engagement means 62 are in the form of a groove. The fastening base 200 is received in the recess 80 when the element 100 is locked to the base, as illustrated in Figure 3B, which will be described in detail later. Figure 3A shows a view of a magnetic fastening system when the retaining item 100, illustrated in the cross-sectional view, approaches the fastening base 200. Before the item 100 is placed over the flap 200, the recess 80 is positioned opposite the upper surface of the flap 200, which is in its retracted state. The flap 200 and the retaining item 100 are equipped, respectively, with the first magnets 120 and the second magnets 20. When the item 100, with its recess 80 opposite the flap 200, is oriented in a specific direction, the second magnets 20 exert an attractive force on the first two magnets 120, thus allowing the flap 200 to be removed from the housing. The said determined direction, which depends on the arrangement of the first magnets 120 and second magnets 20, can be indicated on the article to be retained 100.In one embodiment, the first magnets 120 and second magnets 20 are arranged such that the second magnets 20 exert a force on the first magnets 120, the article 200 having a tendency to move in the specified direction under the effect of this force. Preferably, the upper surface of hatch 200 has a circular shape. The hatch 200 comprises first and second retaining means 160 that move back and forth between a first and second position. In the first position, the mounting base 200 can be received in the recess 80, and the retaining means 160 can be received in the engagement means 62. Figure 3B shows a view of a magnetic fastening system in the locked position, whereby the item to be retained in section view is fixed to the mounting base. In the first position, the first and second retaining means 160, acting as fastening notches, engage in the groove 62. The projecting portions 162 of the retaining means 160 are engaged in the groove, thus locking the item 100. The first retaining means 160 and the second retaining means 160 each comprise, respectively, a first movement magnet 140 and a second movement magnet 140. The retaining article 100 comprises two contact magnets 40. The magnets The contact magnets 40 exert a force on the movement magnets 140, which holds the first retaining means 160 and the second retaining means 160 within the engagement means 62 in the locked position. Before the engagement of the retaining means 160 and the groove 62, the contact magnets 40 begin to exert a force on the movement magnets 140, and therefore on the retaining means 160. Under the effect of this magnetic force, the retaining means 160 move and protrude from the hatch 200. In one embodiment, the first and second retaining means 160 are blocked in rotation by a translation groove 170 along which the retaining means 160 are mobile in a back-and-forth motion. In the locked position illustrated in [Fig. 3B], article 100 is locked in the axial direction. However, article 100 can rotate under the effect of a torque. Fig. 3C represents a view of a magnetic fastening system in the unlocked position, where the item to be held is rotated at an angle relative to the position shown in Fig. 3B. Following a rotation from the locked position, for example by 90 degrees, the two second magnets 20 exert a force on the movement magnets 140, which allows the retaining means 160 to move to the second position in which the retaining means 160 do not protrude out of the hatch 200, thus the first and second retaining means 160 are disengaged from the groove 62. In the second position, the contact magnets 40 exert a repulsive force on the first two magnets 120, which pushes the hatch 200 back into its retracted position in the structure 300. At the same time, the force that the two second magnets 20 exert on the movement magnets 140 contributes to this repulsive effect. Figure 4 shows an arrangement of the magnets in the magnetic mounting base and an arrangement of the magnets in the retaining element according to one embodiment. In the illustrated embodiment, the south poles of the first two magnets 120 of the mounting base 200 point in substantially the same direction, while the north poles of the movement magnets 140 point in substantially the same direction. The first two magnets 120 and the two movement magnets 140 are arranged in a rotating and alternating manner, for example, in a plane. The first two magnets 120 are arranged oppositely in the plane. In a preferred embodiment, these magnets 120 and 140 are arranged at equal angular distances. Preferably, the two movement magnets 140 are housed in two cavities in the retaining means 160. Advantageously, the retaining means 160 can be driven by a magnetic force exerted on the two moving magnets 140. In one embodiment, the restraint means 160 comprise li- miters 164 which come to rest against the base 200 of fixing when the means 160 of retention protrude. The article 100 to be retained comprises two secondary magnets 20 and two contact magnets 40. The contact magnets 40 and the secondary magnets 20 are arranged in a rotating and alternating manner, such that the contact magnets 40 and the secondary magnets 20 are respectively opposed. The four magnets 20, 40 are preferably in the same plane, for example, arranged on a magnet support. In a preferred embodiment, the secondary magnets 20 are arranged symmetrically with respect to the axis connecting the contact magnets 40. The four magnets 20, 40 are preferably arranged at equal angular distances. When the item 100 to be retained approaches the fixing base 200, the magnets 20, 40 move in the direction of the indicated arrow. Figure 5A illustrates the arrangement of the magnets of the magnetic fixing base 200 and the magnets of item 100 to be retained when the magnetic fixing system is in the locked position. We observe that the magnets 20, 40 of the article 100 to be retained are in their position of attractive force, that is to say, the second magnets 20 exert an attractive force on the first two magnets 120 of the hatch 200 which allows the hatch to move towards the article 100 and to come out of its retracted state, at the same time, the contact magnets 40 exert an attractive force on the movement magnets 140 of the retaining means 160 which makes the protruding parts serving as notches 162 appear. The notches 162 engage in the groove 62 of the article 100 (not illustrated), which allows the fixing of the article 100 to the base 200, the magnetic forces between the magnets of the article 100 and the base 200 reinforcing this fixing. In one embodiment, each notch 162 advantageously includes an electrical element 167 such as a copper electrical terminal for establishing electrical contact. In the locked position, these terminals come into contact with electrical connection elements provided in the engagement means 62 of article 100, advantageously enabling an electrical connection between the article and the mounting base. Figure 5B shows an arrangement of the magnets on the magnetic mounting base 200 and an arrangement of the magnets on the retaining item 100, after a 1 / 4 turn rotation of the retaining item 100 on Figure 5SA relative to the mounting base 200, with the magnetic mounting system in the unlocked position. The second magnets 20 take the position of the contact magnets 40 on Figure 5SA. Since the north poles of the magnets 40 are oriented in the opposite direction to those of the magnets 20, the latter exert a repulsive force on the movement magnets 140 located below the magnets 20 in this position, resulting in a de- The retention means 160 are positioned in the groove 170 so that they retract and do not protrude. Simultaneously, the contact magnets 40 located above the first two magnets 120 exert a repulsive force on the first magnets 120, pushing the mounting base 200 downwards into its retracted state. At the same time, the force exerted by the second two magnets 20 on the movement magnets 140 contributes to this repulsive effect. Figure 6 shows a partial cross-sectional view of the magnetic fastening system in the locked position according to one embodiment. The retaining element 100 advantageously comprises two opposing electrical elements 67, such as two electrical terminals connected to an electrical circuit of the element 100, which are arranged in the engagement means 62. In the locked position, the electrical element 167 of each notch 162 comes into contact with an electrical element 67, thus establishing an electrical connection between the retaining element 100 and the fastening base 200. In one embodiment, the fastening base further comprises retaining magnets 135, 155 arranged to hold the base 200 retracted into the housing of the structure 300. Figure 7 shows an exploded view of a retaining element 100 according to one embodiment. The retaining element 100 essentially comprises a body 70, a magnet holder 30 which includes arrangements such as cavities 32, 34 for holding the second magnets 20 and the contact magnets 40. The body 70 has a mounting interface 90 having a recess 80 and an opening 82 through which the mounting base can be inserted for attachment. The magnet holder 30 is located above the recess 80. The retaining element 100 further includes a cover 30 which is intended to enclose the magnets 20, 40 in the cavities 32, 34. Figure 8 illustrates an exploded view of a magnetic retractable hatch 200 according to one embodiment. The hatch 200 essentially comprises an enclosing body having two lateral openings 112, two retaining means 160, the first magnets 120, and the movement magnets 140. The enclosing body essentially consists of a removable upper part 110 having lateral openings 112 and a cradle 150. Preferably, the two elements 110 and 112 are assembled by a screw 190. The two retaining means 160 are movable back and forth in a translation groove 112 within the enclosing body, the outer ends 162 of the two retaining means 160 being able to protrude from the enclosing body and form notches through the lateral openings 112. Each of the two retaining means 160 includes a movement magnet 140. The first magnets 120 are held opposite each other by a magnet retaining plate 130 inside the enclosing body.The retractable hatch 200 is equipped with means to prevent the rotation of the plate. retention and therefore that of the first magnets 120 relative to the surrounding body. Preferably, the anti-return magnets 135, 155 are provided for this purpose. The retaining plate has cavities to hold the first anti-return magnets 135 which are coupled with the second anti-return magnets 155 fixed to the outside of the surrounding body, for example on an external surface of the cradle 150. The present invention relates generally to a magnetic base 200 for retaining an article 100 having engagement means 62, such as the cup holder shown in [Fig. 7]. The base 200 comprises first and second retaining means 160 that are movable back and forth between a locked and an unlocked position. In the locked position, the retaining means 160 can be received into the engagement means 62 of the article 100. The first retaining means 160 comprises a first movement magnet 140, and the second retaining means 160 comprises a second movement magnet 140. When a magnetic force is applied to each of the movement magnets 140, the first and second retaining means 160 move apart and are expelled toward the locked position. In some embodiments, the first retaining means 160 and the second retaining means 160 are blocked in rotation by a translation groove 170. In some embodiments, the mounting base 200 comprises two initial magnets 120 whose south poles point in a direction opposite to that of the north pole of the movement magnets 140. The first two magnets 120 and the two movement magnets 140 are arranged in a rotating and alternating manner. In some embodiments, the fixing base 200 includes anti-return means, such as anti-return magnets 135, used to keep the base 200 retracted in the housing of the structure 300. In general, the magnets used in this invention can be permanent magnets made of a ferromagnetic material.
