Description

Title of the invention: Blackout device

[0001] The present invention relates to a blackout device.

[0002] In general, the present invention relates to the field of blackout devices comprising a motorized drive device moving a screen, between at least a first position and at least a second position.

[0003] A motorized drive device includes an electromechanical actuator of a movable closing, obscuring or sun protection element, such as a shutter, a door, a grille, a blind or any other equivalent material, hereinafter referred to as a screen.

[0004] Blinding devices comprising a housing, a screen, a roller tube, and an electrical energy storage device are already known. The screen is rolled up onto the roller tube. The roller tube is located inside the housing. The housing comprises a wall. The wall of the housing comprises an inner surface. The electrical energy storage device comprises a battery and two supports. The battery is cylindrical and is located inside the housing. Each support is fixed to the inner surface of the wall of the housing by means of at least one fastener. Each support holds the battery in position inside the housing. The battery comprises a plurality of electrical energy storage elements. In addition, each support comprises a retaining element.

[0005] However, these occultation devices have the disadvantage that each support is thicker than the battery's envelope volume.

[0006] Thus, the size of the electrical energy storage device inside the trunk is not optimized.

[0007] Furthermore, such an assembly of the electrical energy storage device does not allow the battery to be moved away from the screen when the latter is being wound or unwound around the winding tube inside the box.

[0008] The present invention aims to resolve the aforementioned drawbacks and to propose a concealment device allowing a battery to be mounted inside a box of the concealment device, while minimizing the radial footprint of an electrical energy storage device inside the box.

[0009] In this regard, the present invention relates to a blackout device comprising at least:

[0010] - a chest,

[0011] - a screen,

[0012] - a winding tube, the screen being windable onto the winding tube, the tube the winding mechanism being located inside the box, and

[0013] - an electrical energy storage device,

[0014] the safe comprising at least:

[0015] - a first wall, the first wall comprising at least a first surface interior,

[0016] the electrical energy storage device comprising at least:

[0017] - a battery, the battery being cylindrical and being disposed inside the trunk, and

[0018] - two supports, each support being fixed against the first inner surface of the first wall of the trunk, by means of at least one fastening element, and each support holding the battery in position inside the trunk,

[0019] the battery comprising at least:

[0020] - a plurality of electrical energy storage elements,

[0021] each support comprising at least:

[0022] - a retaining element.

[0023] According to the invention, the battery further comprises at least two assembly elements, each assembly element bearing against at least one of the electrical energy storage elements. Each assembly element comprises at least one first receiving zone, the retaining element of each support being assembled with one of the assembly elements at the first receiving zone of said assembly element. The first receiving zone of each assembly element has an outer diameter smaller than the outer diameter of the battery. Furthermore, the retaining element of each support has an inner diameter smaller than the outer diameter of the battery.

[0024] Thus, the first receiving area of ​​each battery assembly element is housed inside the retaining element of one of the supports, while ensuring that the retaining element of each of the supports does not protrude or protrudes very little from a volume of the battery envelope, so as to minimize the radial bulk of the electrical energy storage device inside the trunk and to move the battery away from the screen, when winding or unwinding the latter around the winding tube inside the trunk.

[0025] In this way, the assembly of the first receiving area of ​​each of the battery assembly elements inside the retaining element of one of the supports makes it possible to limit, or even avoid, an overthickness of the retaining element of each of the supports compared to the battery envelope volume.

[0026] In addition, the electrical energy storage device can be installed in a box of smaller dimensions, particularly in terms of thickness and height.

[0027] Consequently, the small size of the electrical energy storage device inside the trunk makes it possible, on the one hand, to avoid contact between the screen and the battery when the screen is being wound or unwound around the tube winding inside the box, and, on the other hand, maximizing the winding diameter of the screen around the winding tube inside the box.

[0028] According to an advantageous feature of the invention, each assembly element is supported against at least one of the electrical energy storage elements of the battery along a longitudinal axis of the battery.

[0029] According to another advantageous feature of the invention, each assembly element comprises at least one second receiving zone, one of the electrical energy storage elements being assembled on one of the assembly elements at the level of the second receiving zone of said assembly element.

[0030] According to another advantageous feature of the invention, the battery further comprises at least one heat-shrinkable sleeve. In addition, each assembly element is held to at least one of the electrical energy storage elements by means of the heat-shrinkable sleeve.

[0031] According to another advantageous feature of the invention, the plurality of electrical energy storage elements comprises at least:

[0032] - a first end electrical energy storage element, the first an end electrical energy storage element comprising at least one first end face, the first end face being oriented towards the outside of the battery, and

[0033] - a second end electrical energy storage element, the second end electrical energy storage element being opposite the first end electrical energy storage element, the second end electrical energy storage element comprising at least one first end face, the first end face being oriented towards the outside of the battery.

[0034] In addition, one of the assembly elements is supported against the first end face of the first end electrical energy storage element and the other of the assembly elements is supported against the first end face of the second end electrical energy storage element.

[0035] Alternatively, each electrical energy storage element comprises a first end face and a second end face. Each assembly element is arranged between two adjacent electrical energy storage elements. Furthermore, each assembly element is supported, on one side, by the first end face of one of the adjacent electrical energy storage elements and, on the other side, by the second end face of the other adjacent electrical energy storage element.

[0036] According to another advantageous feature of the invention, each assembly element comprises at least one electrical connection element, the electrical connection element being electrically connected with the two storage elements of adjacent electrical power.

[0037] According to another advantageous feature of the invention, the retaining element of each support is an elastic snap-fit ​​fastening element.

[0038] According to another advantageous feature of the invention, the shading device further comprises at least one motorized drive device. The motorized drive device comprises at least one electromechanical actuator. The electromechanical actuator comprises at least one electric motor, the electric motor being powered by the battery. In addition, the winding tube is arranged so as to be driven in rotation by the electromechanical actuator.

[0039] According to another advantageous feature of the invention, the shading device further comprises at least one photovoltaic panel, the battery being supplied with electrical energy by means of the photovoltaic panel.

[0054] A home automation system 100 according to the invention is described first, with reference to Figures 1 and 2. This home automation system 100 comprises at least one closing, shading, or solar protection device 3, according to a first embodiment of the invention. This home automation system 100, installed in a building (not shown), has an opening 1 in which a window 40 or a door is located (the latter is shown only in Figure 1). This home automation system 100 is equipped with at least one screen 2 belonging to the closing, shading, or solar protection device 3, in particular a motorized roller shutter.

[0055] The closing, shading or sun protection device 3 is hereinafter referred to as the "shading device". The shading device 3 comprises the screen 2.

[0056] The shading device 3 can be a roller shutter, a fabric blind or a blind with adjustable slats, a rolling gate, a grille, or even a door. The present invention applies to all types of shading devices.

[0057] A roller shutter conforming to the first embodiment of the invention is described with reference to Figures 1 and 2.

[0058] The occulting device 3 includes a motorized drive device 5. The motorized drive device 5 includes an electromechanical actuator 11 illustrated in [Fig.3].

[0059] The occultation device 3 further comprises a winding tube 4. The screen 2 is windable onto the winding tube 4. In addition, the winding tube 4 is arranged so as to be driven in rotation by the electromechanical actuator 11.

[0060] Thus, the screen 2 of the obscuring device 3 is wound onto the winding tube 4 or unwound around it, the winding tube 4 being driven by the device motorized drive 5, in particular by the electromechanical actuator 11.

[0061] In this way, the screen 2 is mobile between a rolled-up position, in particular high, and an unrolled position, in particular low, and vice versa.

[0062] The screen 2 of the shading device 3 is a closing, shading and / or sun protection screen, rolling and unrolling around the winding tube 4, the inner diameter of which is greater than the outer diameter of the electromechanical actuator 11, so that the electromechanical actuator 11 can be inserted into the winding tube 4, when assembling the shading device 3.

[0063] The electromechanical actuator 11, in particular of tubular type, allows the winding tube 4 to be rotated around an axis of rotation X, so as to move, in particular unwind or wind, the screen 2 of the occulting device 3.

[0064] In an assembled state of the occulting device 3, the electromechanical actuator 11 is inserted into the winding tube 4.

[0065] In a known manner, the roller shutter, which forms the blackout device 3, comprises a curtain including horizontal slats hinged to one another, forming the screen 2 of the roller shutter 3, and guided by two lateral tracks 6, shown only in [Fig.2]. These slats are joined when the curtain 2 of the roller shutter 3 reaches its fully extended lower position.

[0066] The occultation device 3 further comprises a box 9.

[0067] In the case of a roller shutter, the raised, fully retracted position corresponds to the bearing of an end slat 8, for example L-shaped, of the curtain 2 of the roller shutter 3 against an edge of the housing 9 of the roller shutter 3, or to the stopping of the end slat 8 in a programmed upper limit position. Furthermore, the lower, fully retracted position corresponds to the bearing of the end slat 8 of the curtain 2 of the roller shutter 3 against a threshold 7 of the opening 1, or to the stopping of the end slat 8 in a programmed lower limit position.

[0068] Here, the screen 2 is configured to be moved, by means of the motorized drive device 5, between an open position, corresponding to the rolled-up position and which can also be called the first end-of-stroke position or upper end-of-stroke position FdCH, and a closed position, corresponding to the unrolled position and which can also be called the second end-of-stroke position or lower end-of-stroke position FdCB.

[0069] Thus, the electromechanical actuator 11 is configured to drive, in other words drives, in movement the screen 2, between the first end position FdCH and the second end position FdCB, and vice versa.

[0070] The first slat of the roller shutter 3, opposite the final end slat 8, is connected to the winding tube 4 by means of at least one joint 10, in particular a band-shaped attachment piece.

[0147] Advantageously, the output shaft 20 of the electromechanical actuator 11 is disposed inside the winding tube 4 and at least partly outside the housing 17 of the electromechanical actuator 11.

[0148] Here, one end of the output shaft 20 protrudes from the housing 17 of the electromechanical actuator 11, in particular from the second end 17b of the housing 17 opposite the first end 17a.

[0149] Advantageously, the output shaft 20 of the electromechanical actuator 11 is configured to drive a connecting element 22 in rotation. This connecting element 22 is connected to the winding tube 4, in particular in the assembled configuration of the occulting device 3. The connecting element 22 is, for example, made in the form of a wheel.

[0150] When the electromechanical actuator 11 is switched on, the electric motor 16 and the gearbox 19 rotate the output shaft 20. In addition, the output shaft 20 of the electromechanical actuator 11 rotates the tube winding 4 via the connecting element 22.

[0151] Thus, the winding tube 4 causes the screen 2 of the occulting device 3 to rotate, so as to open or close the opening 1.

[0152] Advantageously, the obscuring device 3 and, more particularly, the motorized drive device 5 further comprises an electrical power supply device 26, visible in [Fig. 2]. The electromechanical actuator 11 is electrically connected to the electrical power supply device 26.

[0153] The occulting device 3 and, more particularly, the electrical power supply device 26 includes at least one electrical energy storage device 33.

[0154] The electrical energy storage device 33 includes at least one battery 24.

[0155] Advantageously, the shading device 3 and, more particularly, the electrical power supply device 26 further comprises at least one photovoltaic panel 25.

[0156] In this case, battery 24 is of the rechargeable type.

[0157] The electrical power supply device 26 and, more particularly, the battery 24 is configured to supply, in other words supplies, electrical energy to the electromechanical actuator 11 and, more particularly, the electronic control unit 15 and the electric motor 16.

[0158] Thus, the electrical power supply device 26 and, more particularly, the battery 24 makes it possible to supply electrical power to the electromechanical actuator 11, without itself being electrically connected to a mains power supply network.

[0159] Here, the photovoltaic panel 25 is electrically connected to the battery 24, by an electrical connection L.

[0160] The electromechanical actuator 11 is electrically connected to the electrical power supply device 26 and, more particularly, to the battery 24, in particular by means of the electrical power supply cable 18.

[0161] The battery 24 is configured to supply, in other words, provides electrical energy to the electromechanical actuator 11, in particular the electronic control unit 15 and the electric motor 16. In addition, the battery 24 is configured to be supplied, in other words, is supplied with electrical energy by the photovoltaic panel 25.

[0162] Thus, the charging of the battery 24 is carried out by solar energy, by means of the photovoltaic panel 25.

[0163] Battery 24 is located inside trunk 9.

[0164] In [Fig. 2], the battery 24 is shown outside the compartment 9 in order to better visualize the components of the electrical power supply device 26. This is independent of the location of battery 24 inside trunk 9.

[0165] When the torque support 21 includes a display device, the operating parameter that this display device allows to be viewed is advantageously a state of charge of the battery 24.

[0166] Here, the electromechanical actuator 11 includes the power supply cable 18 enabling its supply of electrical energy, in particular the power supply of the electronic control unit 15 and the power supply of the electric motor 16, in particular from the battery 24.

[0167] Here, the battery 24 is electrically connected directly to the electronic control unit 15, by the power supply cable 18.

[0168] Advantageously, the battery 24 comprises a plurality of energy storage elements 32, 32a, 32b, in particular electrically connected in series. The energy storage elements 32, 32a, 32b of the battery 24 may be, in particular, accumulators or cells.

[0169] Advantageously, the photovoltaic panel 25 comprises a plurality of photovoltaic cells 43. In this case, the battery 24 is supplied with electrical energy by means of the photovoltaic cells 43 of the photovoltaic panel 25.

[0170] The motorized drive device 5, in particular the photovoltaic panel 25 and / or the electronic control unit 15, includes charging elements configured to charge the battery 24, from the solar energy recovered by the photovoltaic panel 25. In this case, the current flows between the organs 15, 24 and 25 through a wired link, which may be separate from the electrical power supply cable 18.

[0171] Thus, the charging elements configured to charge the battery 24, from solar energy, make it possible to convert the solar energy recovered by the photovoltaic panel 25 into electrical energy.

[0172] Alternatively, in addition, the motorized drive device 5, in particular the electromechanical actuator 11, is supplied with electrical energy from an auxiliary battery, not shown, or from a mains power supply network, in particular from the commercial AC network, in particular depending on a state of charge of the battery 24.

[0173] Here, the electronic control unit 15 comprises a single electronic board 55. Furthermore, the electronic board 55 is configured to control the electric motor 16, to enable the charging of the battery 24, and optionally, to access parameterization and / or configuration functions of the electromechanical actuator 11, by means of selection and, optionally, display elements, not shown. As mentioned above, the battery charging elements 24 can be arranged on the electronic board 55.

[0174] In an alternative configuration, not shown, the electronic control unit 15 comprises a first electronic board and a second electronic board. The first electronic board is configured to control the electric motor 16. Furthermore, the second electronic board is configured to allow the charging of the battery 24 and, optionally, access to parameterization and / or configuration functions of the electromechanical actuator 11, by means of selection and, optionally, display elements, not shown. The battery charging elements 24 may be located on the second electronic board. In the case where the electronic control unit 15 comprises a first electronic board and a second electronic board, not shown, the first electronic board of the electronic control unit 15 may be located inside the housing 17 of the electromechanical actuator 11.Furthermore, the second electronic board can be arranged inside the torque support 21 of the electromechanical actuator 11. Moreover, the torque support 21 may include a cover, not shown. In addition, the second electronic board can be arranged inside a housing formed between a portion of the torque support 21 and the cover.

[0175] Advantageously, the photovoltaic panel 25 can be fixed on the box 9, on a wall of the building, on one of the side rails 6, on a pane of glass of the window 40 or on a fixed frame of the window 40.

[0176] The electrical energy storage device 33 belonging to the occultation device 3 illustrated in Figures 1 and 2 and conforming to the first embodiment of the invention, as well as the mounting of the battery 24 inside the box 9, are now described in more detail and with reference to Figures 4 to 8.

[0177] The chest 9 includes at least one first wall 9a. The first wall 9a includes at least one first interior surface 9ai.

[0178] Advantageously, the box 9 comprises a second wall 9b, a third wall 9c and a fourth wall 9d. In addition, the first, second, third and fourth walls 9a, 9b, 9c, 9d of the box 9 are connected to each other, in other words are configured to be connected to each other, in particular in the assembled configuration of the obscuring device 3, either by fastening elements, not shown, which may be, for example, fastening elements by interlocking, by elastic snap-fitting, by riveting or by screwing, or because they belong to the same strip of sheet metal or form a single piece, in particular made of plastic.

[0179] Advantageously, the case 9 has an opening 48 for the passage of the screen 2 when winding and unwinding the latter around the winding tube 4, as illustrated in [Fig.4].

[0180] Here and as illustrated in [Fig. 2], the chest 9 is parallelepiped in shape and has four angles 44a, 44b, 44c, 44d, including a right upper angle 44a, an angle upper left 44b, a lower right angle 44c and a lower left angle 44d.

[0181] Alternatively, and as illustrated in [Fig. 4], the chest 9 is parallelepiped in shape and has three angles 44a, 44b, 44c, including an upper left angle 44a, an upper right angle 44b, and a lower right angle 44c. The lower right angle 44c has a large radius of curvature to connect the third and fourth walls 9c, 9d of the chest 9. In this case, the chest 9 lacks a lower left angle 44d, since the first wall 9a and the fourth wall 9d are not contiguous, so as to form the opening 48.

[0182] Advantageously, the chest 9 is defined by a length L9, a height H9 and a thickness E9, in other words a depth.

[0183] The electrical energy storage device 33 further comprises at least two supports 37. On the one hand, each support 37 is fixed against the first inner surface 9ai of the first wall 9a of the compartment 9, by means of at least one fastener, not shown. And, on the other hand, each support 37 holds the battery 24 in position inside the compartment 9.

[0184] Here, the two supports 37 are identical. The following description of a support applies to either of these two supports 37.

[0185] Each support 37 includes at least one retaining element 42.

[0186] Advantageously, each support 37 further comprises an arm 4L. The arm 41 comprises at least a first surface 41a. The first surface 41a is configured to be supported, in other words is supported, against the first inner surface 9ai of the first wall 9a of the box 9, in particular in the assembled configuration of the obscuring device 3.

[0187] Advantageously, the retaining element 42 is connected to the arm 4L. The battery 24 includes an outer surface 24e. The retaining element 42 includes at least a second surface 42a. The second surface 42a is configured to be supported, that is to say, is supported, against the outer surface 24e of the battery 24, particularly in the assembled configuration of the occulting device 3. In addition, the second surface 42a is curved, that is to say, has a concavity.

[0188] Here, the concavity of the second surface 42a is oriented towards battery 24, in particular in the assembled configuration of the occultation device 3.

[0189] Here, the retaining element 42 and the arm 41 of each support 37 form a single piece. In other words, each support 37 is a single piece consisting of the retaining element 42 and the arm 4L

[0190] In an alternative, not shown, the retaining element 42 and the arm 41 of each support 37 are two separate parts assembled together by means of at least one fixing element, which may be, for example, by elastic snap-fit, by snap-fit ​​or by screwing.

[0191] The battery 24 further comprises at least two assembly elements 39.

[0192] Here, the two assembly elements 39 are identical. The following description of an assembly element applies to either of these two assembly elements 39.

[0193] Each assembly element 39 is supported, in other words is configured to be supported, against at least one of the electrical energy storage elements 32, 32a, 32b, in this case one of the end electrical energy storage elements 32a, 32b in this first embodiment of the invention, in particular in an assembled configuration of the battery 24 and along a longitudinal axis X24 of the battery 24.

[0194] Each assembly element 39 includes at least one first receiving area 45. In addition, the retaining element 42 of each support 37 is assembled, in other words is configured to be assembled, with one of the assembly elements 39 at the level of the first receiving area 45 of the assembly element 39 concerned, in particular in an assembled configuration of the electrical energy storage device 33.

[0195] Thus, the first receiving area 45 of one of the assembly elements 39 is configured to receive in support, in other words receives in support, a retaining element 42 of one of the supports 37.

[0196] Advantageously, battery 24 is cylindrical, in other words, has a circular cross-section.

[0197] Here, battery 24 is defined by an outside diameter 024ext, which is the outside diameter of its outer surface 24e.

[0198] Advantageously, the first receiving area 45 of each assembly element 39 is convex in shape and, more particularly, is cylindrical, preferably with a circular cross-section.

[0199] Here, the first receiving area 45 of each assembly element 39 is defined by an outside diameter 045ext.

[0200] The outside diameter 045ext of the first receiving zone 45 of each assembly element 39 is less than the outside diameter 024ext of the battery 24.

[0201] Advantageously, the retaining element 42 of each support 37 is convex in shape and, more particularly, is in the shape of an open ring or clamp, preferably with a circular cross-section.

[0202] Here, the retaining element 42 of each support 37 is defined by an inner diameter 042int.

[0203] Advantageously, the inner diameter 042int of the retaining element 42 is measured when the retaining element 42 is not constrained by one of the assembly elements 39, that is to say, in the absence of one of the assembly elements 39 in the volume defined by the second surface 42a.

[0204] In addition, the inner diameter 042int of the retaining element 42 of each support 37 is less than the outer diameter 024ext of the battery 24.

[0205] Thus, the first receiving area 45 of each assembly element 39 of the battery 24 is housed inside the retaining element 42 of one of the supports 37, while ensuring that the retaining element 42 of each of the supports 37 does not protrude or protrudes very little in relation to an envelope volume of the battery 24, in particular in a radial direction to the longitudinal axis X24, so as to minimize the radial bulk of the electrical energy storage device 33 inside the box 9 and to move the battery 24 away from the screen 2, when winding or unwinding the latter around the winding tube 4 inside the box 9.

[0206] Here, the envelope volume of the battery 24 is equal to a cylinder, in particular with a circular cross-section, centered on the longitudinal axis X24 and with a diameter equal to the outside diameter 024ext.

[0207] In this way, the assembly of the first receiving area 45 of each of the assembly elements 39 of the battery 24 inside the retaining element 42 of one of the supports 37 makes it possible to limit, or even avoid, an overthickness of the retaining element 39 of each of the supports 37 compared to the envelope volume of the battery 24.

[0208] In addition, the electrical energy storage device 33 can be installed in a box 9 of smaller dimensions, in particular in terms of thickness E9 and height H9.

[0209] Consequently, the small size of the electrical energy storage device 33 inside the box 9 makes it possible, on the one hand, to avoid contact of the screen 2 with the battery 24, when winding or unwinding it around the winding tube 4 inside the box 9, and, on the other hand, to maximize a winding diameter 02 of the screen 2 around the winding tube 4 inside the box 9. A circle of diameter 02, which delimits the maximum size of the screen 2 inside the box 9, is represented by a dashed line in [Fig.4].

[0210] Furthermore, the assembly of the first receiving area 45 of each of the assembly elements 39 of the battery 24 inside the retaining element 42 of one of the supports 37 allows the battery 24 to be positioned as close as possible to one of the corners 44a, 44b, 44c, 44d of the box 9, so as to optimize the size of the electrical energy storage device 33 inside the box 9 and to move the battery 24 away from the screen 2, when winding or unwinding the latter around the winding tube 4 inside the box 9.

[0211] Preferably, the difference between the outer diameter 024ext of the battery 24 and the inner diameter 042int of the retaining element 42 of each support 37 is su- greater than or equal to twice the thickness of the retaining element 42.

[0212] In the embodiment illustrated in figures 4 and 5, the assembly of the first receiving area 45 of each of the assembly elements 39 of the battery 24 inside the retaining element 42 of one of the supports 37 allows the battery 24 to be positioned as close as possible to the angle 44a of the box 9.

[0213] In an alternative, not shown, the assembly of the first receiving area 45 of each of the assembly elements 39 of the battery 24 inside the retaining element 42 of one of the supports 37 allows the battery 24 to be positioned as close as possible to the angle 44b, the angle 44c or the angle 44d of the trunk 9.

[0214] Advantageously, each support 37 and each assembly element 39 are made of a plastic material.

[0215] Thus, each support 37 and each assembly element 39 made of plastic makes it possible to avoid damaging the battery 24, when installing it inside the box 9, by means of the supports 37 and the assembly elements 39, in particular compared to supports and assembly elements made of metal, which could have sharp edges.

[0216] In addition, in the event of damage to the battery 24, during its installation inside the trunk 9, each support 37 and each assembly element 39 made of plastic prevents the creation of a short circuit in the battery 24, which could generate a chemical reaction at the level of its electrical energy storage elements 32, 32a, 32b, since each support 37 and each assembly element 39 are not electrically conductive.

[0217] Advantageously, the outer diameter 024ext of the battery 24 is within a predetermined range of values, the predetermined range of values ​​being defined between a first minimum value and a second maximum value.

[0218] Thus, each support 37 is compatible with different values ​​of outer diameter 024ext of the battery 24, so as to be universal within the predetermined range of values.

[0219] In this way, a single reference support 37 is developed and marketed for the different reference batteries 24 developed and marketed intended to be installed in the trunk 9.

[0220] Advantageously, the first minimum value of the range is greater than or equal to ten millimeters, preferably greater than or equal to thirteen millimeters, and the second maximum value of the range is less than or equal to fifty millimeters, preferably less than or equal to forty millimeters.

[0221] By way of non-limiting example, the value of the outside diameter 024ext of battery 24 may be seventeen millimeters or twenty-three millimeters.

[0222] Here and as illustrated in [Fig. 5], the electrical energy storage device 33 includes two supports 37 and the battery 24 includes two assembly elements 39.

[0223] In an alternative, not shown, the electrical energy storage device 33 comprises three or more supports 37 and the battery 24 comprises three or more assembly elements 39, in particular depending on a length L24 of the battery 24.

[0224] Advantageously, the number of supports 37 is equal to the number of assembly elements 39.

[0225] Thus, the supports 37 and the assembly elements 39, respectively two or more in number, make it possible to ensure alignment of the battery 24 inside the box 9 and, more particularly, as close as possible to one of the corners 44a, 44b, 44c, 44d of the box 9.

[0226] Advantageously, the length L9 of the chest 9 is greater than or equal to one hundred and twenty-five millimeters, in particular when the value of the external diameter 024ext of the battery 24 is on the order of seventeen millimeters.

[0227] Advantageously, the retaining element 42 of each support 37 is an elastic snap-fit ​​fastening element.

[0228] Thus, fixing each assembly element 39 with one of the supports 37 does not require any tools.

[0229] Advantageously, the inner diameter 042int of the retaining element 42 of each support 37 is less than or equal to the outer diameter 045ext of the first receiving zone 45 of each assembly element 39.

[0230] Here and as illustrated in [Fig.7], the inner diameter 042int of the retaining element 42 of each support 37 is equal to the outer diameter 045ext of the first receiving area 45 of each assembly element 39.

[0231] Advantageously, the retaining element 42 of each support 37 includes at least one guide element 47. In addition, the guide element or each guide element 47 of the retaining element 42 is configured to guide, in other words, guides, one of the assembly elements 39 inside the retaining element 42, when the battery 24 is assembled on each of the supports 37.

[0232] Here, the retaining element 42 of each support 37 comprises two guide elements 47, in this case a guide element 47 at each end of the clamp-shaped retaining element 42. Only one of the retaining elements 42 of one of the supports 37 is visible in [Fig. 4].

[0233] In this case, only the guide elements 47 of the retaining element 42 of each support 37 protrude from the volume of the battery 24 envelope, without the bulk of the electrical energy storage device 33 inside the box 9 having an impact on the winding diameter 02 of the screen 2 around the winding tube 4.

[0234] Advantageously, each assembly element 39 comprises at least one second receiving area 49. In addition, one of the electrical energy storage elements 32, 32a, 32b, in this case one of the end electrical energy storage elements 32a, 32b in this first embodiment of the invention, is assembled, in other words is configured to be assembled, on one of the assembly elements 39 at the level of the second receiving area 49 of the assembly element 39 concerned, in particular in the assembled configuration of the battery 24.

[0235] Thus, the second receiving zone 49 of one of the assembly elements 39 is configured to receive in support, in other words receives in support, one of the electrical energy storage elements 32, 32a, 32b.

[0236] Here, the second receiving area 49 of each assembly element 39 comprises a concavity 51 and a collar 53. In addition, a portion of one of the electrical energy storage elements 32, 32a, 32b, in this case one of the end electrical energy storage elements 32a, 32b in this first embodiment of the invention, is configured to be housed, in other words is housed, inside the concavity 51 and the collar 53 is configured to cover, in other words covers, a portion of one of the electrical energy storage elements 32, 32a, 32b, in this case one of the end electrical energy storage elements 32a, 32b in this first embodiment of the invention, particularly in the assembled configuration of the battery 24.

[0237] Advantageously, each assembly element 39 comprises a first end 39a and a second end 39b. The second end 39b is opposite the first end 39a.

[0238] Here, each assembly element 39 comprises a single second receiving zone 49. In addition, the second receiving zone 49 is provided at the second end 39b of the assembly element 39.

[0239] Advantageously, the battery 24 comprises two ends 24a, 24b, opposite each other.

[0240] Advantageously, the plurality of electrical energy storage elements 32, 32a, 32b comprises a first end electrical energy storage element 32a and a second end electrical energy storage element 32b. The second end electrical energy storage element 32b is opposite the first end electrical energy storage element 32a.

[0241] The first end electrical energy storage element 32a and the second end electrical energy storage element 32b each comprise a first end face 32e and a second end face 32i. The first end face 32e is oriented outwards from the battery 24. The second end face 32i is oriented inwards from the battery 24. In other words, the second end face 32i is opposite to the first end face 32e.

[0242] In addition, one of the assembly elements 39 is supported, in other words is configured to be supported, against the first end face 32e of the first end electrical energy storage element 32a and the other of the assembly elements 39 is supported, in other words is configured to be supported, against the first end face 32e of the second end electrical energy storage element 32b, in particular in the assembled configuration of the battery 24.

[0243] Thus, each of the assembly elements 39 is arranged at one of the ends 24a, 24b of the battery 24.

[0244] Advantageously, the battery 24 further comprises at least one heat-shrinkable sleeve 50. In addition, each assembly element 39 is held, in other words is configured to be held, with at least one of the electrical energy storage elements 32, 32a, 32b, in this case one of the end electrical energy storage elements 32a, 32b in this first embodiment of the invention, by means of the heat-shrinkable sleeve 50, in particular in the assembled configuration of the battery 24.

[0245] Here, the battery 24 comprises a single heat-shrinkable sleeve 50. In addition, all the electrical energy storage elements 32, 32a, 32b of the battery 24 are held together by the single heat-shrinkable sleeve 50. Furthermore, each of the assembly elements 39, which are respectively disposed at one of the ends 24a, 24b of the battery 24, are held with one of the first and second end electrical energy storage elements 32a, 32b by the single heat-shrinkable sleeve 50.

[0246] Advantageously, the collar 53 of the or of each second receiving area 49 of each assembly element 39 is covered, in other words is configured to be covered, by the heat-shrinkable sleeve 50, particularly in the assembled configuration of the battery 24.

[0247] Advantageously, the fixing element of each support 37 against the first wall 9a of the chest 9 is a fixing element by bonding.

[0248] Thus, in this case, fixing each support 37 against the first wall 9a of the chest 9 does not require any tools.

[0249] Alternatively or in addition, the fixing element of each support 37 against the first wall 9a of the chest 9 is a fixing element by screwing or riveting.

[0250] Advantageously, in the case where the fixing of each support 37 against the first wall 9a of the chest 9 is implemented by screwing or riveting, the arm 41 of each support 37 includes a through hole 46.

[0251] Thus, the through hole 46 allows a screw or rivet to pass through the arm 41 of each support 37, so as to screw or rivet each support 37 against the first wall 9a of chest 9.

[0252] Advantageously, in the case where the fixing of each support 37 against the first wall 9a of the chest 9 is implemented by screwing or riveting, the first wall 9a of the chest 9 includes a screwing or riveting hole, not shown.

[0253] Here, each support 37 can be fixed against the first wall 9a of the chest 9 either by means of the fixing element by bonding, or by means of the fixing element by screwing or riveting, or by means of the fixing element by bonding and the fixing element by screwing or riveting.

[0254] Here, the bonding fixing element is an adhesive, in particular a double-sided adhesive.

[0255] In the case where the bonding fixing element is an adhesive, it has a cover, not shown, which is to be removed when the first surface 41a of the arm 41 of one of the supports 37 is pressed against the inner surface 9ai of the first wall 9a of the box 9.

[0256] In the case where the fixing of each support 37 against the first wall 9a of the chest 9 is implemented, on the one hand, by gluing, by means of an adhesive, and, on the other hand, by screwing or riveting, the adhesive is pierced beforehand by means of a tool or during the insertion of the screw or rivet, through the through hole 46 of the arm 41 of the support 37.

[0257] In the case where the fixing of each support 37 against the first wall 9a of the box 9 can be carried out either by gluing, or by screwing, or by riveting, an installer has the choice between the three possibilities.

[0258] Advantageously, the battery 24 is held in position, in other words is configured to be held in position, inside the box 9, by means of the supports 37 and the assembly elements 39, in a horizontal position, in other words in a position extending along the length L9 of the box 9, in particular in the assembled configuration of the blackout device 3.

[0259] Here, the horizontal position of battery 24 is understood to be parallel to the ground and to the axis of rotation X.

[0260] The mounting of the battery 24 inside the box 9 of this blackout device 3 is carried out by fixing each support 37 against the first inner surface 9ai of the first wall 9a of the box 9, by means of at least one fixing element, by gluing and / or by screwing or riveting, then, by assembling each of the assembly elements 39 of the battery 24 with one of the retaining elements 42 of each support 37, in particular by elastic snap-fit.

[0262] Thus, a first power supply wire 54 is electrically connected to the first end electrical energy storage element 32a and a second power supply wire 54 is electrically connected to the second end electrical energy storage element 32b.

[0263] Advantageously, the power supply wires 54 are electrically connected to an electrical connector 56, so as, on the one hand, to supply electrical energy to the electromechanical actuator 11 and, on the other hand, to recharge electrical energy to the battery 24 either by the photovoltaic panel 25, or by a charger, or by an auxiliary battery.

[0264] Advantageously, the first power supply wire 54 is electrically connected to the first end electrical energy storage element 32a, in particular at the first end face 32e of the first end electrical energy storage element 32a, via a first conductive strip 59. Furthermore, the second power supply wire 54 is electrically connected to the second end electrical energy storage element 32b, in particular at the first end face 32e of the second end electrical energy storage element 32b, via a second conductive strip 59.

[0265] Here, the first and second conductive strips 59 are made of a metallic material, such as, for example, steel, copper or brass, have a flat rectangular surface and are bent so as to be in electrical contact with a terminal of the first or second end electrical energy storage element 32a, 32b.

[0266] Advantageously, the first power supply wire 54 is electrically connected to the first conductive strip 59 by a solder joint. Similarly, the second power supply wire 54 is electrically connected to the second conductive strip 59 by a solder joint.

[0267] Advantageously, the first and second conductive strips 59 are held in position inside the heat-shrinkable sleeve 50, particularly in the assembled configuration of the battery 24.

[0268] Advantageously, the battery 24 further comprises a safety device, not shown. In addition, the safety device is disposed, or rather configured to be disposed, between the second receiving zone 49 of one of the assembly elements 39 and the first or second end electrical energy storage element 32a, 32b assembled against the assembly element 39 concerned, in particular in the assembled configuration of the battery 24.

[0269] Thus, the assembly element 39 makes it possible to protect the safety device, in particular when handling the battery 24.

[0270] Advantageously, the safety device is located at the second end 24b of the battery 24, in other words at an electrical output of the battery 24.

[0271] Here, the safety device is an electronic switch to electrically protect the battery 24 from a short circuit of the electrical energy storage elements 32, 32a, 32b, so as to prevent them from heating up and causing a chemical reaction.

[0272] In the second embodiment, shown in Figures 9 to 13, the elements analogous to those of the first embodiment bear the same reference numerals and function as explained above. The following mainly describes what distinguishes this second embodiment from the first. In the following, when a reference numeral is used in the description without being reproduced in Figures 9 to 13, or reproduced in Figures 9 to 13 without being mentioned in the description, it corresponds to the object bearing the same reference numeral in one of Figures 1 to 8.

[0273] With reference to Figures 9 to 13, the occultation device 3 according to the second embodiment of the invention is now described, and more particularly, the electrical energy storage device 33.

[0274] Here, each assembly element 39 includes two second receiving zones 49. In addition, a first second receiving zone 49 is provided at the first end 39a of the assembly element 39 and a second receiving zone 49 is provided at the second end 39b of the assembly element 39.

[0275] Here, each assembly element 39 is arranged between two adjacent electrical energy storage elements 32, 32a, 32b, which can also be called neighbors. Each electrical energy storage element 32, 32a, 32b is defined, along the longitudinal axis X24, between a first end face 32e and a second end face 32i. The second end face 32i is opposite the first end face 32e.

[0276] In addition, each assembly element 39 is supported, in other words is configured to be supported, on the one hand, against the first end face 32e of one of the adjacent electrical energy storage elements 32, 32a, 32b and, on the other hand, against the second end face 32i of the other of the adjacent electrical energy storage elements 32, 32a, 32b.

[0277] Thus, each of the assembly elements 39 is disposed between two adjacent electrical energy storage elements 32, 32a, 32b of the battery 24, in other words each of the assembly elements 39 is not disposed at one of the ends 24a, 24b of the battery 24.

[0278] Here and as illustrated in [Fig. 10], the electrical energy storage device 33 also includes two supports 37 and the battery 24 also includes two assembly elements 39.

[0279] Here, the two supports 37 are identical. The following description of a support applies to either of these two supports 37. Similarly, the two assembly elements 39 are identical. The following description of an assembly element applies to either of these two assembly elements 39.

[0280] Here, battery 24 includes several heat-shrink sleeves 50a, 50b, 50c, in this case three in number.

[0281] A first subassembly 52a consists of the first end electrical energy storage element 32a and, optionally, one or more other electrical energy storage elements 32. The first end electrical energy storage element 32a and, optionally, the other electrical energy storage element(s) 32 of the first subassembly 52a are held together by a first heat-shrinkable sleeve 50a.

[0282] A second subassembly 52b consists of the second end electrical energy storage element 32b and, optionally, one or more other electrical energy storage elements 32. The second end electrical energy storage element 32b and, optionally, the other electrical energy storage element(s) 32 of the second subassembly 52b are held together by a second heat-shrinkable sleeve 50b.

[0283] A third subassembly 52c consists of one or more electrical energy storage elements 32 arranged between the first and second subassemblies 52a, 52b. The other electrical energy storage element(s) 32 of the third subassembly 52c are held together by a third heat-shrinkable sleeve 50c.

[0284] A first assembly element 39 is arranged between the first subassembly 52a and the third subassembly 52c, as seen in [Fig. 11]. Furthermore, the first assembly element 39 is held, on the one hand, with one of the electrical energy storage elements 32a, 32 of the first subassembly 52a by the first heat-shrinkable sleeve 50a and, on the other hand, with one of the electrical energy storage elements 32 of the third subassembly 52c by the third heat-shrinkable sleeve 50c.

[0285] A second assembly element 39 is arranged between the second subassembly 52b and the third subassembly 52c, as seen in [Fig. 11]. In addition, the second assembly element 39 is held, on the one hand, with one of the electrical energy storage elements 32b, 32 of the second subassembly 52b by the second heat-shrinkable sleeve 50b and, on the other hand, with one of the electrical energy storage elements 32 of the third subassembly 52c by the third heat-shrinkable sleeve 50c.

[0286] Here, each assembly element 39 includes an electrical connection element 57. In addition, the electrical connection element 57 is electrically connected with the two electrical energy storage elements 32, 32a, 32b adjacent to the assembly element 39 concerned.

[0287] Thus, the two adjacent electrical energy storage elements 32, 32a, 32b of the battery 24 between which one of the assembly elements 39 is disposed are electrically connected together, as are the other adjacent electrical energy storage elements 32, 32a, 32b of the battery 24 between which no assembly element 39 is disposed, only their terminals being in electrical contact.

[0288] Here, the electrical connection element 57 is arranged in a central hole 38 of the assembly element 39. In addition, the electrical connection element 57 has a shape similar to that of one of the electrical energy storage elements 32, 32a, 32b, but of reduced dimensions compared to the electrical energy storage elements 32, 32a, 32b.

[0289] Here, each assembly element 39 includes at least one guide zone 60. In addition, the guide zone 60 is configured to hold in position, that is, holds in position, one of the first and second flat conductive strips 59, particularly in the assembled configuration of the battery 24.

[0290] In this embodiment, the guide area 60 is made in the form of a longitudinal groove formed in the assembly element 39.

[0291] Thanks to the present invention, regardless of the embodiment, the first receiving area of ​​each assembly element of the battery is housed inside the retaining element of one of the supports, while ensuring that the retaining element of each of the supports does not protrude or protrudes very little from a volume of the battery envelope, so as to minimize the radial bulk of the electrical energy storage device inside the trunk and to move the battery away from the screen, when winding or unwinding the latter around the winding tube inside the trunk.

[0292] In this way, the assembly of the first receiving area of ​​each of the battery assembly elements inside the retaining element of one of the supports makes it possible to limit, or even avoid, an overthickness of the retaining element of each of the supports compared to the battery envelope volume.

[0293] Numerous modifications can be made to the embodiment examples described above, without departing from the scope of the invention.

[0294] Alternatively, not shown, the assembly of the electrical energy storage elements 32, 32a, 32b with the assembly elements 39 can be implemented by combining the first and second embodiments, i.e., one of the assembly elements 39 is arranged at one of the ends 24a, 24b of the battery 24 and that the other of the assembly elements 39 is disposed between two adjacent electrical energy storage elements 32, 32a, 32b.

[0295] Alternatively, and not shown, the power supply device 26 further includes a charger. This charger is configured to be plugged into, or is plugged into, a wall outlet so as to recharge the battery 24 from a mains power supply. This charger constitutes an external power supply.

[0296] In an alternative, not shown, the power supply device 26 further comprises an auxiliary battery, the auxiliary battery being configured to recharge the battery 24. Thus, the battery 24 can be recharged by means of the auxiliary battery, which forms an external power supply, particularly when the shading device 3 is located far from a wall outlet. In addition, the auxiliary battery can be used to recharge the battery of other electrical equipment, particularly portable devices, such as, for example, a mobile phone or a laptop computer.Furthermore, such an auxiliary battery may have at least two electrical outputs, in particular a first output delivering a voltage of 12 volts to supply electrical energy to battery 24 and a second output delivering a voltage of 5 volts to supply electrical energy to other electrical equipment, known as portable equipment.

[0297] Furthermore, the envisaged embodiments and variants can be combined to generate new embodiments of the invention, without departing from the scope of the invention.
