[0001] REMOVABLE HARD TOP FOR A MOTOR VEHICLE AND MOTOR VEHICLE

[0002] COMPRISING THE SAME

[0003] Cross-Reference to Related Applications

[0004] This Patent Application claims priority from Italian Patent Application No. 102024000022947 filed on October 15, 2024, the entire disclosure of which is incorporated herein by reference.

[0005] Technical Field

[0006] This invention concerns a removable hard top for a motor vehicle. The invention also relates to a motor vehicle comprising a removable hard top.

[0007] Background

[0008] Motor vehicles are known that comprise the following: a chassis defining a passenger compartment to accommodate the driver and any passengers; a number of wheels rotating with respect to the chassis; and

[0009] - a hard top removably coupled to the chassis and adapted to cover the passenger compartment at a top point thereof, which is opposed to the wheels along a vertical direction of the motor vehicle.

[0010] As is well known, when the hard top is removed, the passenger compartment is directly communicating with the surrounding environment. Conversely, when the hard top is fixed to the chassis, it protects the occupants of the passenger compartment from the weather and outside noise.

[0011] However, the assembly and disassembly of hard tops is generally complicated and sometimes requires the intervention of specialised workers. Therefore, there is a need for a hard top that can be easily assembled and disassembled.

[0012] One purpose of the invention is to respond to the need described above, preferably in a simple and reliable way.

[0013] US9908392B1 describes a vehicle comprising a number of individually controllable top modules. Each of these modules comprises: a frame, an adjustable wind deflector supported by a front end portion of the frame, a window panel supported by the frame, and a first motor configured to selectively open the window panel by moving it away from the front end portion and over its rear end portion when electrically powered. Each module also comprises a sunshade and a second motor configured to selectively adjust the sunshade in a range between a folded up configuration and an unfolded configuration when electrically powered. Each module has a locking mechanism with a locking state to secure the frame in a respective opening of the top and establish a power supply circuit to power the motors; and an unlocking state to remove the frame from the top opening and open the power supply circuit.

[0014] DE3640483C1 describes a fastener for the detachable connection of a removable top to a vehicle body. The fastener has a removable top-mounted connecting part and a receiving part attached to the vehicle body. The connecting part has a threaded sleeve, in the through hole of which a guide bolt is rotatively mounted, while the threaded sleeve is attached to the removable top by means of nuts screwed onto its outer thread. The guide bolt also has two radially projecting locking pins, each of which engages in an insertion opening in the hollow cylindrical receiving part. Adjacent to each insertion opening, there is a respective guide shoulder; the guide shoulders join at a stop cavity. By angular rotation of the guide bolt, the locking pins slide over the guide shoulders and finally engage in the stop cavities, while the disc springs, which surround the guide bolt, are preloaded so that the locking pins are elastically attached.

[0015] US5042869A describes a locking device for coupling a top to the windscreen frame of a motor vehicle comprising an actuating device arranged on a front part of the top frame at the longitudinal centre plane of the vehicle. The actuating device is connected to laterally external locking elements via connecting elements that extend transversely. When the top is in the closed position, the locking elements interact with receiving devices mounted on the windscreen frame. The receiving devices are only accessible from above in order to create a locking device that, while being easy to assemble, ensures smooth operation and enables large stroke movements in a vertical direction. The receiving devices each consist of a closing portion attached to the windscreen on which a bolt extending horizontally is locally mounted. The bolt extends in the longitudinal direction of the vehicle and, when opening and closing the folding top, is operationally connected to a locking hook of the locking element that is guided so it can be moved in the transverse direction of the vehicle.

[0059] Embodiments of the Invention

[0060] In Figure 1, reference number 1 is used to indicate a motor vehicle as a whole. Without implying any loss of generality, the vehicle illustrated is a motor vehicle, preferably a sports car, for example of the cabriolet or roadster type.

[0061] The vehicle 1 comprises, in a known way, a chassis 2 and multiple wheels - not illustrated - rotating with respect to the chassis 2 about respective rotation axes.

[0062] It is possible to define a reference system integral with the vehicle 1 and comprising:

[0063] - a direction X of longitudinal extension; a direction Z orthogonal to the direction X and vertical to the ground on which the wheels are resting; and

[0064] - a direction Y orthogonal to the directions X and Z. The vehicle 1 also comprises a front portion la and a rear portion lb with respect to a forward direction A. The front portion la and the rear portion lb are opposed to each other parallel to the direction X (Figure 1).

[0065] The vehicle 1 also comprises a passenger compartment 3 integral with the chassis 2 and adapted to accommodate a driver and any passengers. The passenger compartment 3 comprises, in turn, a top point 3a, which is opposed to the wheels along the direction Z.

[0066] The vehicle 1 also comprises an electrical power source 4, for example an electrical power storage device such as an electric battery. In a known way, the electric battery 4 comprises a positive terminal 4a and a negative terminal 4b (Figure 1).

[0067] The vehicle 1 also comprises a top 10 removably attached to the chassis 2 and configured to cover the passenger compartment 3 at the top point 3a. Specifically, the top 10 is a hard top, that is, of the non-folding type. For example, the fact that the top 10 is rigid means that it has a similar stiffness to the body of the vehicle 1.

[0068] The top 10 comprises a main body 11 and two connecting elements 12, 13 configured to enable the mechanical attachment of the top 10 to the chassis 2.

[0069] Preferably, but not necessarily, the top 10 also comprises a window 15 formed in the main body 11 (Figure 1). In addition, the main body 11 is preferably made of carbon fibre.

[0070] Advantageously, the top 10 comprises multiple electrical or electronic components 30 integral with the main body 11 and electrically connected to the connecting elements 12, 13. In addition, the connecting elements 12, 13 are configured to be electrically connected to the electrical battery 4.

[0071] In other words, the connecting elements 12, 13 contribute to binding the top 10 to the chassis 2 and, at the same time, allow the top 10 to be electrically connected to the rest of the vehicle 1.

[0072] Specifically, the connecting element 12 is configured to be electrically connected to the negative terminal 4b and the connecting element 13 is configured to be electrically connected to the positive terminal 4a of the electrical battery 4 (Figure 1).

[0073] The connecting elements 12 and 13 are made at least partially of an electrically conductive material. In particular, the connecting elements 12, 13 are made of steel. In addition, the connecting elements 12 and 13 are electrically connected to the components 30 by means of respective electrical conductors 16, for example electrical cables.

[0074] As illustrated in Figures 2, 5 and 6, the connecting elements 12 and 13 comprise a pin 14 extending along a longitudinal axis B.

[0075] Preferably, the connecting elements 12, 13 are identical to each other. Therefore, reference will be made below to the connecting element 12, since the considerations made for the connecting element 12 also apply to the element 13.

[0076] The pin 14 comprises two ends 14a, 14b, which are opposed to each other along the axis B. Specifically, the end 14a is free.

[0077] The pin 14 is axisymmetric with respect to the axis B and comprises, proceeding from the end 14a to the end 14b (Figure 5):

[0078] - a truncated cone section 14c;

[0079] - a cylindrical section 14d;

[0080] - a cylindrical section 14e; and

[0081] - a cylindrical section 14f.

[0082] Specifically, proceeding in the direction oriented from the end 14a to the end 14b, the extension of the cross section of the section 14c transversely to the axis B gradually increases. In addition, the cross-section extension of the section 14d is less than the maximum crosssection extension of the section 14c; the cross-section extension of the section 14e is greater than the crosssection extension of the section 14d; the cross-section extension of the section 14f is greater than the crosssection extension of the section 14e.

[0083] The pin 14 also comprises an opening 14g within which the electrical cable 16 is inserted so as to allow current to flow from the electrical battery 4 to the components 30 via the electrical cable 16. Specifically, the opening 14g is arranged coaxially to the axis B. More specifically, the opening 14g extends from the end 14b to the section 14c. The opening 14g is preferably a blind cylindrical hole inside the connecting element 12 (Figure 6). The connecting elements 12, 13 are preferably arranged on the side of the top 10 configured to face the front portion la of the vehicle 1. In addition, the connecting elements 12, 13 are aligned and spaced apart from each other parallel to the direction Y (Figure 1).

[0084] As illustrated in Figure 5, the top 10 also comprises two bodies 19, to each of which a respective connecting element 12, 13 is attached. The bodies 19 are attached to or in any case integral with the main body 11. Specifically, the bodies 19 are made of polyamide and act as electrical insulators between each connecting element 12, 13 and the main body 11 of the top 10.

[0085] More specifically, the body 19 comprises a through hole 19a arranged coaxially to the axis B. The hole 19a is adapted to be passed through by electrical cable 16 and, therefore, performs the function of a cable guide. In the illustrated embodiment, moreover, the body 19 has a prismatic or essentially prismatic shape.

[0086] In detail, each connecting element 12, 13 is removably attached to the respective body 19. For this purpose, the body 19 comprises two threaded holes 19b and 19c and each connecting element 12, 13 comprises:

[0087] - a plate 19d, to which a respective pin 14 is attached, and provided with two holes 19e and 19f;

[0088] - two screws 19g and 19h, each adapted to engage a respective hole 19e, 19f of the plate 19d and a respective hole 19b, 19c of the body 19.

[0089] Specifically, the hole 19a is interposed between the holes 19b and 19c along a direction orthogonal to the axis B. The plate 19d is also preferably made of metal.

[0090] The chassis 2 comprises two seats 5, each configured to be engaged by a respective connecting element 12, 13 (Figure 2).

[0091] The seats 5 are preferably identical to each other. Therefore, unless otherwise indicated, reference will be made below to only one seat 5, since the considerations made for one of the two seats 5 also apply to the other.

[0092] The seat 5 comprises (Figure 6):

[0093] - a cavity 6 configured to house at least part of the connecting element 12, 13; and

[0094] - an electrically conductive element 7, which is at least indirectly electrically connected to the electrical battery 4 and at least partially faces the cavity 6.

[0095] Specifically, the cavity 6 has a shape corresponding, or essentially corresponding, to the shape of the pin 14. In addition, the pin 14 inside the cavity 6 is configured to contact the electrically conductive element 7.

[0096] The electrically conductive element 7 is also electrically connected to the electrical battery 4 by means of an electrical conductor 17, for example an electrical cable.

[0097] The seat 5 also comprises an opening 9 configured to enable the evacuation of water or other liquids accumulated in the cavity 6. The vehicle 1 preferably comprises a duct 18 fluidically connected to the opening 9 and configured to discharge water or other liquids evacuated from the cavity 6.

[0098] The seats 5 are preferably arranged at the top point 3a and are aligned and spaced apart from each other parallel to the direction Y. In addition, the distance between the seats 5 parallel to the direction Y is equal or similar to the distance between the connecting elements 12 and 13 parallel to the direction Y (Figure 1).

[0099] The components 30 comprise two electric locks 32, 33 for fastening the top 10 to the chassis 2. At the same time, the chassis 2 comprises two lock strikers 44, 45, each configured to cooperate with a respective electric lock 32, 33 (Figure 2).

[0100] Each electric lock 32, 33 comprises a respective mechanism 40 configured to selectively assume:

[0101] - a locked configuration, wherein it is configured to engage the respective lock striker 44, 45; or

[0102] - an unlocked configuration, in which it is configured to disengage the respective lock striker 44, 45.

[0103] The removable top 10 also comprises an electric motor 41, which is operationally connected to the mechanisms 40 of the locks 32, 33 to move them between the respective unlocked and locked configurations. Specifically, the electric motor 41 is configured to operate in a first operating mode, wherein it moves the mechanisms 40 from the unlocked to the locked configurations, or in a second operating mode, wherein it moves the mechanisms 40 from the locked to the unlocked configurations. More specifically, the electric motor 41 is a rotary motor and is configured to rotate in a first rotation direction when in the first operating mode and to rotate in a second rotation direction opposite to the first when in the second operating mode.

[0104] The electric locks 32, 33 are preferably arranged on the side of the top 10 configured to face the rear portion lb of the vehicle 1 (Figure 1).

[0105] The electric locks 32, 33 are aligned and spaced apart from each other parallel to the direction Y. In addition, as shown in Figures 3 and 4, the electric motor 41 is interposed between the electric locks 32 and 33 parallel to the direction Y.

[0106] Similarly, the lock strikers 44 and 45 are aligned and spaced apart from each other parallel to the axis Y. Specifically, the distance between the lock strikers 44 and 45 parallel to the direction Y is equal or similar to that between the electric locks 32, 33 parallel to the direction Y.

[0107] Each lock striker 44 and 45 preferably comprises a respective wire rod.

[0108] As shown in Figure 8, the top 10 comprises two selectors 42 and 43, which are both electrically connected to the electric motor 41. The selector 42 is configured to be electrically connected to the positive terminal 4a and the other selector 43 is configured to be electrically connected to the negative terminal 4b of the electrical battery 4.

[0109] The selectors 42 and 43 can be positioned in, respectively: first operating positions, wherein they are configured to allow electric current to flow between the electrical battery 4 and the electric motor 41 (via connecting elements 12 and 13); second operating positions, wherein they are configured to prevent the electric current from flowing between the electrical battery 4 and the electric motor 41. In other words, the selectors 41 and 42 perform the function of electric switches. Therefore, to enable the operation of the electric motor 41 - and, for example, to enable the unlocking of the electric locks 32 and 33 - both selectors 42 and 43 must be in their respective first operating positions at the same time.

[0110] The selectors 42 and 43 are preferably mechanical buttons, that is, they are adapted to assume respective first physical positions corresponding to the first operating positions and respective second physical positions corresponding to the second operating positions.

[0111] Moreover, the selectors 42 and 43 are preferably arranged on the side of the top 10 facing the passenger compartment 3.

[0112] Again, as shown in Figure 8, the top 10 comprises an electric switch 46 and another electric switch 47, which are electrically connected to the electric motor 41 and configured to selectively vary its power supply polarity.

[0113] Specifically, the electric switch 46 can be positioned in:

[0114] - a first operating position, wherein it allows the electrical connection between the selector 42 and the electric motor 41, and therefore between the positive terminal 4a and the electric motor 41; and

[0115] - a second operating position, wherein it allows the electrical connection between the selector 43 and the electric motor 41, and therefore between the negative terminal 4a and the electric motor 41.

[0116] Similarly, the electric switch 47 can be positioned in:

[0117] - a first operating position, wherein it allows the electrical connection between the selector 42 and the electric motor 41, and therefore between the positive terminal 4a and the electric motor 41; and

[0118] - a second operating position, wherein it allows the electrical connection between the selector 43 and the electric motor 41, and therefore between the negative terminal 4a and the electric motor 41.

[0119] More specifically, when the electric switch 46 is in the first operating position and the other electric switch

[0120] 47 is in the second operating position, the electric motor 41 is configured to operate in either the first operating mode or the second operating mode; when the electric switch 46 is in the second operating position and the electric switch 47 is in the first operating position, the electric motor 41 is configured to operate in the other of either the first operating mode or the second operating mode.

[0121] In other words, the electric switches 46 and 47 perform the function of relays.

[0122] The top 10 also preferably comprises an electric fuse

[0123] 48 electrically connected to the positive terminal 4a and the selector 42.

[0124] The components 30 also preferably comprise one or more of the following (Figure 1):

[0125] - an electrochromic glass 31;

[0126] - a loudspeaker 34;

[0127] - a device 35 for electrically recharging cellphones or other mobile devices;

[0128] - an electronic display 36; and

[0129] - a light-emitting device 37.

[0130] In particular, the electrochromic glass 31 is applied to and / or integrated into the window 15 and is electrically powered via the connecting elements 12 and 13.

[0131] The electrochromic glass 31 is configured to assume a first configuration, to which a first transparency value is associated, and a second configuration, to which a second transparency value greater than the first transparency value is associated. Therefore, the electrochromic glass 31 in the first configuration is more opaque than in the second configuration and allows less light radiation to pass from the outside of the vehicle 1 to the passenger compartment 3.

[0132] The electrochromic glass 31 is also configured to assume other configurations, which are associated with respective transparency values intermediate between the first transparency value and the second transparency value.

[0133] The loudspeaker 34 (only illustrated schematically in Figure 1) is, for example, a speaker or a sound system.

[0134] The light-emitting device 37 (only shown schematically in Figure 1) is, for example, a courtesy light or performs the function of an ambient light. For example, the lightemitting device 37 is also applied to and / or integrated into the window 15.

[0135] The assembly of the top 10 to the chassis 2 is described below.

[0136] In particular, the top 10 is first placed at the top point 3a and the connecting elements 12 and 13 are engaged in their respective seats 5. At this point, the top 10 receives power from the electrical battery 4.

[0137] Subsequently, by virtue of the electrical connection of the top 10 to the rest of the vehicle 1, the mechanisms 40 of the electric locks 32 and 33 are automatically switched from the unlocked to the locked configuration. As a result, the electric locks 32 and 33 engage their respective lock strikers 44 and 45, completing the fastening of the top 10. Specifically, to activate the electric motor 41, the selectors 42 and 43 must both be pressed simultaneously.

[0138] In order to remove the top 10, it is first necessary to change the operating configuration of the electric switches 46 and 47 so as to reverse the supply polarity of the electric motor 41.

[0139] Subsequently, the mechanisms 40 of the electric locks 32 and 33 are automatically switched from the locked to the unlocked configuration, again by pressing both the selectors 42 and 43 simultaneously.

[0140] Disassembly is completed by disengaging the connecting elements 12 and 13 from their respective seats 5.

[0141] During operation, the top 10 covers the passenger compartment 3, protecting the occupants from the weather and outside noise. The top 10 receives electricity from the electrical battery 4 via connecting elements 12 and 13. This electricity can be used to drive the electrical or electronic components 30.

[0142] With reference to Figures 9 to 12, reference number 1' denotes a vehicle according to a second embodiment of this invention. The vehicle 1' is similar to the vehicle 1 and will be described below only as far as it differs from the latter; the same or equivalent parts of the vehicles 1, 1' will be distinguished, where possible, by the same reference numbers.

[0143] The vehicle 1' differs from the vehicle 1 in that it comprises a seat 5' instead of the seat 5.

[0144] The seat 5' is similar to the seat 5 and will be described below only as far as it differs from the latter; the same or equivalent parts of the seats 5; 5' will be distinguished, where possible, by the same reference numbers.

[0145] The seat 5' differs from the seat 5 in that it comprises elastic means 8' operationally connected to the electrically conductive element 7' and configured to elastically load the electrically conductive element 7' to a position wherein it is in contact with the respective connecting element 12', 13' (Figures 10 and 11).

[0146] Specifically, the electrically conductive element 7' can slide along a direction C transverse to the axis B and comprises a surface 7a', which is configured to cooperate in contact with the corresponding connecting element 12', 13', and a surface 7b', which is opposite the surface 7a' along the direction C and is configured to cooperate in contact with the elastic means 8'.

[0147] The elastic means 8' preferably comprise a spiral spring having an axis parallel to the direction C. More specifically, the spiral spring is arranged concentrically to at least one section of the electrical cable 17'.

[0148] The electrically conductive element 7' is a cylindrical or essentially cylindrical shape and comprises a seat 7c' at the surface 7b'. In particular, one of the two axial ends of the spiral spring of the elastic means 8' is housed in the seat 7c' (Figure 11).

[0149] In addition, the seat 5' comprises a body 50' with a recess 51', which houses the elastic means 8' and part of the electrical cable 17'.

[0150] The recess 51' also contains, at least in part, the electrically conductive element 7'. Specifically, the recess 51' faces the cavity 6'. More specifically, the recess 51' comprises cylindrical walls, which act as guides for the movement of the electrically conductive element 7 parallel to the direction C.

[0151] The body 50' is preferably divided into two portions 52', 53' removably attached to each other, in particular by means of threaded connecting elements.

[0152] As illustrated in Figures 10 and 11, the recess 51' extends partly at the portion 52' and partly at the portion 53'.

[0153] In addition, the portion 52' comprises a seat 52c', at which the other of the two axial ends of the spiral spring of the elastic means 8' is housed.

[0154] The body 50' also comprises a through opening 54' for the passage of the electrical cable 17' outside the recess 51'. Specifically, the opening 54' is arranged at the portion 52' and is concentric to the seat 52c' (Figure 11).

[0155] The vehicle 1' also differs from the vehicle 1 in that it comprises the connecting elements 12' and 13' instead of the connecting elements 12 and 13.

[0156] The connecting elements 12', 13' are similar to the connecting elements 12, 13 and will be described below only as far as they differ from the latter; the same or equivalent parts of the connecting elements 12, 13; 12', 13' will be distinguished, where possible, by the same reference numbers .

[0157] The connecting elements 12' and 13' are preferably identical to each other. Therefore, in the following, reference will be made to the connecting element 12', since the considerations made for the connecting element 12' also apply to the element 13'.

[0158] The connecting element 12' comprises a copper portion 14h', which is electrically connected to the electrical cable 16. Specifically, the electrically conductive element 7' is capable of contacting the pin 14 at the portion 14h' (Figure 11).

[0162] The assembly operations of the top 10' are similar to those of the top 10 and will be described below only insofar as they differ from them.

[0163] Specifically, when the pin 14' is inserted into the respective seat 5', the electrically conductive element 7' is moved and the spring of the elastic means 8' is compressed. Once insertion is complete, the elastic means 8' press the electrically conductive element 7' into contact against the pin 14', specifically against the portion 14h'.

[0164] The operation of the top 10' is similar to that of the top 10. Therefore, its description is omitted for the sake of brevity.

[0165] With reference to Figure 13, reference number 1'' denotes a vehicle according to a third embodiment of this invention. The vehicle 1'' is similar to the vehicle 1 and will be described below only as far as it differs from the latter; the same or equivalent parts of the vehicles 1; 1'' will be distinguished, where possible, by the same reference numbers.

[0167] The connecting element 12'', 13" is similar to the connecting element 12, 13 and will be described below only as far as it differs from the latter; the same or equivalent parts of the connecting elements 12'', 13" will be distinguished, where possible, by the same reference numbers.

[0168] The connecting elements 12'' and 13 " are preferably identically to each other. Therefore, in the following, reference will be made to the connecting element 12'', since the considerations made for the connecting element 12" also apply to the element 13" .

[0169] The connecting element 12'' comprises a copper portion 14h" , which is electrically connected to the electrical cable 16.

[0170] More specifically, the portion 14h'' extends from the end 14a'' towards the end 14b''. Specifically, the portion 14h'' extends along the entire section 14c'' and along part of the section 14d''. In other words, the entire tip of the pin 14'' is made of copper (Figure 13).

[0171] More specifically, the pin 14'' comprises a seat 14i'' adapted to house the portion 14h'' and an insulating element 141'', also housed in the seat 14i' and interposed between the seat 14i'' and the portion 14h''. For example, the insulating element 141'' is made of polyamide. Specifically, the insulating element 141'' acts as an electrical insulator between the section 14c'' (made of steel) and the portion 14h'' (made of copper).

[0172] The operation of the top 10'' is similar to that of the top 10. Therefore, its description is omitted for the sake of brevity.

[0173] With reference to Figure 14, reference number denotes a vehicle according to a fourth embodiment of this invention. The vehicle is similar to the vehicle 1 and will be described below only as far as it differs from the latter; the same or equivalent parts of the vehicles 1;1 ''' will be distinguished, where possible, by the same reference numbers.

[0174] The vehicle 1''' differs from the vehicle 1 in that it comprises a connecting element 12''' and 13''' instead of the connecting element 12 and 13.

[0175] The connecting element 12''', 13''' is similar to the connecting element 12, 13 and will be described below only as far as it differs from the latter; the same or equivalent parts of the connecting elements 12''', 13''' will be distinguished, where possible, by the same reference numbers. The connecting elements 12''' and 13''' are preferably identically to each other. Therefore, in the following, reference will be made to the connecting element 12''', since the considerations made for the connecting element 12''' also apply to the element 13'''.

[0176] The connecting element 12''' comprises two bushings 20''' and two washers 21''' made of electrically insulating material, for example polyamide. The bushings 20''' and washers 21, , ,are intended to electrically isolate the pin 14''' from the body 19'''.

[0177] Specifically, each bushing 20''' engages a respective hole 19e, 19f. In addition, each screw 19g and 19h engages a respective bushing 20''', which is inserted into the respective hole 19e, 19f.

[0178] In addition, each washer 21''' is fitted around a respective screw 19g and 19h on the side of the plate 19d opposite the pin 14'''.

[0179] Some additional bushings 20''' and washers 21''' are shown separately from the connecting element 12''' by way of example in Figure 14.

[0180] The operation of the top IO''' is similar to that of top 10. Therefore, its description is omitted for the sake of brevity.

[0181] With reference to Figure 15, reference number denotes a vehicle according to a fifth embodiment of this invention. The vehicle 1'''' is similar to the vehicle 1 and will be described below only as far as it differs from the latter; the same or equivalent parts of the vehicles 1; 1'''' will be distinguished, where possible, by the same reference numbers. The vehicle 1'''' differs from the vehicle 1 in that it comprises a connecting element 12" " and 13'''' instead of the connecting element 12 and 13.

[0182] The connecting element 12"" , 13'''' is similar to the connecting element 12, 13 and will be described below only as far as it differs from the latter; the same or equivalent parts of the connecting elements 12"" , 13'''' will be distinguished, where possible, by the same reference numbers.

[0183] The connecting elements 12"" and 13'''' are preferably identical to each other. Therefore, in the following, reference will be made to the connecting element 12"" , since the considerations made for the connecting element 12"" also apply to the element 13''''.

[0184] The top 10"" comprises a body 19'''', to which the pin 14"" is attached. The body 19'''' is made of insulating material, for example polyamide.

[0185] Specifically, the body 19'''' comprises a seat 19a"" , at which the pin 14"" is housed on the side of the end 14b''''.

[0186] The operation of the top 10"" is similar to that of the top 10. Therefore, its description is omitted for the sake of brevity.

[0187] From the above, the advantages of the vehicle 1; 1'; 1" ; 1'" ; 1''''aand of the top 10; 10'; 10" ; 10" '; 10"" according to the invention are clear.

[0188] In particular, since the top 10; 10'; 10" ; 10'" ; 10"" comprises connecting elements 12, 13; 12', 13'; 12" , 13" ; 12'" , 13'" ; 12"" , 13"" that are configured to allow both the mechanical fastening and the electrical connection of the removable top 10; 10'; 10''; 10'''; 10'''' to the rest of the vehicle, the assembly and disassembly of the top are facilitated in comparison with the known vehicles discussed in the introduction to this description. In fact, by virtue of the electrical connection of the top 10; 10'; 10''; 10'''; 10''' to the electrical battery 4, the top is electrified and can be equipped with the electrical or electronic components 30. The components 30, in turn, can help facilitate assembly and disassembly.

[0190] Since the top 10; 10'; 10''; 10''; 10’’’; 10’’’’ comprises the selectors 42 and 43, it is possible to limit the risk that the electric locks 32 and 33 are mistakenly unlocked. In fact, the shifting of the mechanism 40 of the locks from the locked to the unlocked configuration can only be achieved when both the selectors 42 and 43 are in the respective first operating positions.

[0191] Since the components 30 may comprise the electrochromic glass 31, the loudspeaker 34, the device 35 for charging mobile devices, the electronic display 36 and the lightemitting device 37, it is possible to improve the comfort of vehicle 1; 1'; 1''; 1’’’; users and provide new opportunities for in-vehicle entertainment.

[0192] Since the seats 5' comprise the elastic means 8', which are operationally connected to the electrically conductive element 7' and that elastically load it in contact against the respective connecting elements 12', 13'; 12'', 13''; 12''', 13'''; 12'''', 13'''', it is possible to ensure electrical contact between the connecting elements and the seats.
