Abstract
Description
Technical Field
[0001] This invention belongs to the field of manufacturing motorized saddle-type vehicles with at least two wheels. Specifically, this invention relates to saddle-type vehicles of the electric or hybrid type, and therefore to saddle-type vehicles equipped with a battery pack. More specifically, this invention relates to saddle-type vehicles equipped with a simplified system for removing and repositioning the battery. Background Technology
[0002] A two-wheeled saddle-mounted vehicle typically comprises a front section supporting at least one steering wheel and a rear section supporting at least one drive wheel. These components are supported by a frame that also supports a powertrain (or traction unit) for the purpose of allowing the vehicle to move. Torque generated by the motor assembly is transmitted to the drive wheels / multiple drive wheels via a transmission system.
[0003] Generally, saddle-riding vehicles typically have two, three, or four wheels; the front section (or front end section) of the vehicle is supported by the front section of the frame. In addition to the steering wheel, the front section of the frame also supports the handlebars. The rear section (or rear end section) of the vehicle is supported by the rear section of the frame, which supports both the rear drive wheel and the saddle. Finally, the middle section of the vehicle, located between the front and rear sections, is supported by the central section of the frame, which extends between the front and rear sections.
[0004] In electric or hybrid vehicles, traction is generated at least in part by energy stored in battery cells, which include one or more battery packs that power an electric motor. Therefore, these vehicles are equipped with an electric powertrain system that includes an electric motor, a transmission for connecting the electric motor to the drive wheels, and a power assembly to which the battery belongs.
[0005] The powertrain is typically supported by the rear section of the chassis, which must also be configured to house all other components, devices, and / or units necessary to ensure the operation of the powertrain. These include, for example, the control unit for the electric motor and / or the battery charging unit.
[0006] The need to position all these components leads to an overall size problem, which is even more pronounced in the case of hybrid vehicles where the rear portion of the frame also supports a heat-absorbing motor for charging the battery.
[0007] This problem is generally solved by reducing the size of the battery pack and making the battery pack as compact as possible with other components.
[0008] Nevertheless, the capacity of a battery pack in terms of charge is inherently related to the volume it occupies, so reducing the volume allocated to the battery pack will result in a reduction in autonomous driving time.
[0009] Furthermore, the compactness of the battery pack and other components makes it difficult to access the battery itself, resulting in a lengthy and complex process for removing and inserting the battery during charging.
[0010] In fact, batteries in electric or hybrid motor vehicles are charged by connecting them to a power source and / or a specific mains power supply, both of which use alternating current (AC). Currently, charging stations installed in public places for electric or hybrid vehicle batteries use direct current (DC), and therefore the only way to charge batteries in motorcycles and mopeds is to have an available 220V power outlet. Since this is not always readily available, in most cases, the driver must remove the battery to charge it at home or in the office and then reposition it back into its casing.
[0011] US Patent 5477936 discloses a battery cell that is divided into two symmetrical portions relative to the longitudinal axis of a vehicle. Each portion includes two battery packs arranged longitudinally to achieve high battery pack autonomy, small overall size, and effective cooling.
[0012] Patent application WO 2018 / 178837 describes a motorcycle including a pair of batteries arranged on opposite sides relative to the longitudinal center plane of the motorcycle frame, wherein each battery is supported by a support member that is movable between a retracted position and an extended position.
[0013] The problem with vehicles equipped with this type of battery cell is the complexity of removing and repositioning the battery pack when it needs to be connected to a power source or generator.
[0014] In fact, removing the battery pack requires using a screwdriver to remove the screws, peeling off the cover from the relevant container, inserting your hand into the narrow space at the rear, and painstakingly removing the battery at the risk of getting your hands dirty and / or injured. After the battery is charged, the same steps must be performed in reverse order, which presents even more difficulty.
[0015] Another problem with electric or hybrid saddle-type vehicles is that increasing the vehicle's driving autonomy necessitates increasing the size of the battery pack, thus increasing not only the overall size of the battery cells but also their weight. This makes removing and repositioning the battery pack even more difficult.
[0016] Currently, no known vehicle is equipped with at least two batteries that allow for quick and easy removal for charging and subsequent quick and easy repositioning of the batteries.
[0017] The applicant has observed a trend toward proposing motor vehicles with a single battery, or motor vehicles with multiple batteries that are difficult to access, often clamped together and / or connected to other components to minimize the overall lateral size of the vehicle. Clearly, this trend is difficult to reconcile with two needs: the need for sufficient driving autonomy to meet normal usage requirements; and / or the need for the ability to easily and quickly remove the battery for charging and then equally easily and quickly reposition it. Therefore, a new technological solution is needed to overcome these drawbacks. Summary of the Invention
[0018] The main objective of this invention is to provide an electric or hybrid type of saddle-mounted vehicle that allows for overcoming the limitations of the known solutions described above.
[0019] To this end, the first objective of the present invention is to provide a saddle-mounted vehicle equipped with a suitable power supply assembly that, in addition to ensuring sufficient driving autonomy, allows for simple and quick removal and repositioning of the battery.
[0020] Another object of the present invention is to provide a saddle-type vehicle having a power assembly that allows for quick and easy removal / repositioning of the battery while ensuring a reduction in the overall lateral size of the vehicle during operation.
[0021] Another object of the present invention is to provide an electric or hybrid type of motor vehicle that does not require the use of tools to remove and reposition the battery and is easy to manufacture at a competitive cost.
[0022] The applicant has observed that the aforementioned objectives and purposes can be achieved by providing the power assembly with: at least one first pair of batteries arranged on opposite sides relative to the longitudinal center plane of the vehicle; a movable support for each battery; and a moving device that releases and / or determines the simultaneous rotation of the support between a retracted position and an extended position. With this solution, the space occupied by the battery during driving is reduced (e.g., in the retracted position, i.e., compact) and laterally offset in the extended position, thereby simplifying battery removal / repositioning.
[0023] Specifically, the present invention relates to a saddle-riding vehicle comprising a frame extending primarily in a longitudinal direction and including a front portion, a central portion, and a rear portion. The front portion supports a front end portion, which includes a steering assembly pivotally connected to the front end portion of the frame to control at least one steering wheel of the vehicle. The rear portion supports a rear end portion, which includes a saddle and at least one drive wheel disposed below the saddle. The central portion supports a middle portion, which connects the front end portion and the rear end portion. The vehicle further includes: a power system connected to the frame and including at least one electric motor operatively connected to the at least one drive wheel; and a power assembly adapted to power the electric motor to allow traction of the vehicle, the power assembly including at least one first pair of batteries arranged on opposite sides relative to the longitudinal center plane of the vehicle and orthogonal to the axis of rotation of the at least one drive wheel.
[0024] According to the invention, each battery is supported by a corresponding support member that is movable between a retracted position and an extended position. Each support member is operatively connected to a moving device that releases and / or determines the rotation of the support member itself about a corresponding axis of rotation.
[0025] According to the invention again, the moving device causes two supports to rotate simultaneously, such that both supports occupy either the retracted position or the extended position. Preferably, the moving device includes a pair of rods, each rod having a first end that engages with a corresponding support and a second end that is fixed to a common pin; the moving device also includes an actuator acting on the common pin to determine the movement of the rods.
[0026] As mentioned, this combination of features makes it possible to produce motor vehicles that have high driving autonomy due to the presence of at least one pair of batteries, and small overall lateral dimensions due to the possibility of keeping the batteries in the retracted position during driving and the possibility of easily and quickly removing the batteries when reaching the extended position.
[0027] Furthermore, this type of vehicle does not require tools for removing and assembling batteries and is easy to manufacture at a competitive cost.
[0028] According to a preferred embodiment, the support member is rotatable about a corresponding axis of rotation parallel to the central plane. In a possible embodiment, the axis of rotation is inclined relative to the vehicle's support plane. Alternatively, these axes of rotation are orthogonal to the axis of rotation of the at least one drive wheel.
[0029] Preferably, the pin can be moved vertically in the longitudinal center plane by means of the actuator, which determines the movement toward the extended position toward the support or the retracted position toward the support by controlling the upward or downward translation of the pin.
[0030] In a possible implementation, the moving device includes a coupling / disengagement system comprising at least one first coupling element that is removably engaged with a second coupling element, the second coupling element being integral with at least one of the supports to lock the latter in a retracted position; after the coupling elements are disengaged, the at least one of the supports can rotate freely about a corresponding axis of rotation to reach an extended position.
[0031] Preferably, for each of the batteries, the disconnection system includes a first coupling element associated with the frame and a second coupling element integral with the corresponding support, wherein each first coupling element and the corresponding second coupling element are removably engaged to lock the corresponding support in the retracted position.
[0032] Even more preferably, the connection / disconnection system includes a manually and / or electrically actuated control unit that determines the disconnection or engagement of each first connection element with its corresponding second connection element.
[0033] In one possible implementation, the control unit selectively intervenes with the first connecting element to independently disconnect one of the supports from the other. Alternatively, the control unit is configured to simultaneously intervene with the first connecting element to simultaneously disconnect the supports.
[0034] In a possible implementation, the motor vehicle is provided with a safety device that is at least configured to trigger movement of the support member from the retracted position to the extended position.
[0035] Preferably, the moving device includes a damper element suitable for controlling the rotational speed of the support.
[0036] According to a preferred embodiment, the battery and corresponding support are positioned at the rear end portion and supported by a battery retainer frame connected to the rear portion of the vehicle frame.
[0037] Preferably, each battery is provided with a clamping device adapted to further simplify removal from the corresponding support. Attached Figure Description

[0049] The same reference numerals and letters in the accompanying drawings identify the same elements or parts. Detailed Implementation
[0050] Referring to the foregoing figures, the present invention therefore relates to a saddle-type vehicle generally indicated by reference numeral 1.
[0051] The term "saddle-type vehicle" in this document refers to any moped or motorcycle having at least two wheels, that is, having at least one front wheel and at least one rear wheel. Therefore, this definition includes: two-wheeled motorcycles; three-wheeled motorcycles having two front steering wheels and one rear drive wheel, or having one front steering wheel and a pair of rear drive wheels; and four-wheeled vehicles having, for example, two front steering wheels and two rear drive wheels.
[0052] Therefore, vehicle 1 will also be referred to as motor vehicle 1 or motorcycle 1 in the following text.
[0053] Vehicle 1 includes a frame 2, which in turn includes a front portion 2A, a central portion 2B, and a rear portion 2C (see...). Figure 4 and Figure 11 ).
[0054] The front portion 2A of the frame 2 supports the front end portion 3 of the motor vehicle 1, which includes a steering assembly 4 pivotally connected to the front portion 2A. The steering assembly 4 controls at least one steering wheel 5 (or front wheel 5) (see...). Figure 1 and Figure 12 ).
[0055] In a particular embodiment not shown in the accompanying drawings of the motor vehicle 1, the front end portion 3 includes two front wheels 5, which are connected to each other and to the front portion 2A of the frame 2 by means of a steering rolling four-bar linkage.
[0056] The rear portion 2C of the frame 2 supports the rear end portion 6, which includes a saddle 7 (only on the rear end portion 6). Figure 11 and Figure 12 (as shown in the diagram) and at least one drive wheel 9 (or rear wheel 9) supported by a fork 99, the fork 99 being hinged to the rear portion 2C of the frame 2 (see also...). Figure 4 and Figure 12 In this regard, in the embodiment shown in the accompanying drawings, the rear end portion 6 includes two drive wheels 9 supported by fork-shaped members 99, which are hinged to the rear end portion 2C for rotation about an axis X parallel to the axis of the drive wheels 9. The rear end portion 6 is also provided with at least one shock absorber 44 (in... Figure 7 and Figure 8As shown in the figure, the shock absorber 44 is also operatively arranged between the fork 99 and the elements of the rear portion 2C of the frame 2 according to known principles.
[0057] Vehicle 1 includes an intermediate section 10 connecting the front end portion 3 and the rear end portion 6 (see...). Figure 1 and Figure 12 The middle section 10 is supported by the central section 2B of the frame 2 and is of the foot pedal type, that is, it provides support for the driver's feet.
[0058] The frame 2 extends mainly along the longitudinal direction L, which is substantially orthogonal to the axis of rotation M of the drive wheel 9 and therefore parallel to the direction in which the vehicle 1 moves forward when it is in motion.
[0059] Specifically, for the purposes of this invention, the term "longitudinal direction L" refers to a direction parallel to the direction of forward movement of vehicle 1 and orthogonal to the direction of rotation axis M of the drive wheel. The term "lateral direction T" refers to a direction substantially orthogonal to the longitudinal direction L and parallel to the rotation axis M of the drive wheel 9. Finally, the term "normal direction N" refers to a direction orthogonal to both the longitudinal direction L and the lateral direction T. These three directions are defined by… Figure 2 and Figure 12 The diagrams show the half-lines L, T, and N (relative to two different embodiments of the motor vehicle 1 according to the invention). The arrows drawn on these half-lines indicate the directions of travel. These arrows indicate the forward, left, and upward directions relative to any point on the vehicle 1, respectively.
[0060] Therefore, the terms "longitudinal or longitudinal," "lateral or transverse," and "normal or normal" refer to the longitudinal direction L, the transverse direction T, and the normal direction N, respectively. The terms "in front of," "to the left of," and "above" refer to... Figure 2 and Figure 12 The arrows in the diagram indicate the direction. Similarly, the terms "behind," "to the right," and "below" indicate the direction indicated by the arrows. Figure 2 and Figure 12 The arrows in the image indicate the opposite direction.
[0061] exist Figure 5 and Figure 6 (involving the first implementation) and Figures 17 to 18(Regarding the second embodiment), the longitudinal center plane AA of vehicle 1 is indicated. This plane AA extends primarily along the longitudinal direction L of the vehicle, but also along the normal direction N, thus being orthogonal to the lateral direction T and therefore orthogonal to the axis of rotation M of the drive wheel 9, and this plane AA divides vehicle 1 into two substantially symmetrical halves: a right half and a left half. When vehicle 1 is in the use position, the longitudinal center plane AA is a substantially vertical plane.
[0062] The motorcycle 1 includes a power system 110, which in turn includes at least one electric motor 111 and a transmission 112 operatively connecting the electric motor 111 to the at least one drive wheel 9. In its embodiment, as shown in the figures, the power system 110 also includes a clutch, a gearbox, and a transmission assembly in a known manner. The clutch may be a "dry" disc type or alternatively an "oil bath" type, or any other type suitable for this purpose. The transmission 112 includes a plurality of gear mechanisms adapted to generate torque on the hub shaft of the drive wheel 9.
[0063] Generally, the configuration of the power system 110 is irrelevant to the purpose of this invention. In particular, the configuration and operation of the electric motor 111 and the transmission 112 are well known to those skilled in the art and will therefore not be described further. Furthermore, the power system 110 may also be a hybrid type and may include a thermal motor.
[0064] In any case, the vehicle 1 according to the invention includes a power supply assembly 12-12' adapted to supply power to an electric motor 111 to allow traction of the vehicle 1. The power supply assembly 12-12' includes at least one first pair of batteries 12, 12', which are arranged on opposite sides relative to the longitudinal center plane AA of the vehicle 1. In other words, at least one first battery 12 is located in the right half of the vehicle 1, and at least one second battery 12' is located in the left half of the vehicle 1, as shown in the figures (e.g., Figure 4 and Figure 5 or Figure 13 and Figure 14 As can be seen from the middle, two or more pairs of batteries 12, 12' can be set up, which are similarly positioned relative to the longitudinal center plane AA and arranged longitudinally side by side with the first pair.
[0065] Batteries 12 and 12' can be charged using a charger unit 50, which includes a charging module 51 and a connector (electrical socket) 52 for connecting the charging module 51 to a power source and / or a specific mains power supply. (See also...) Figure 2 and Figure 3As can be seen, the charging module 51 is preferably supported by the rear part 2C of the frame 2 in a position below the saddle 7.
[0066] Reference Figure 3 and Figure 4 According to known solutions, the electric motor 11 can be controlled via a control unit 59 that includes an inverter module. Preferably, the control unit is also supported at the rear position 2C of the frame 2.
[0067] The motor vehicle 1 is also provided with a service battery 17 for starting the vehicle 1 and / or for supplying power to other electrically operated devices installed in the vehicle, as indicated below. Figure 3 and Figure 4 The preferred mounting position of the service battery 17 is shown, such that the service battery 17 is supported by the rear portion 2C of the frame 2 in a position near the middle portion 2B or near the middle portion 10 of the motor vehicle 1.
[0068] The aforementioned instructions for the power system 110, charger unit 50, control unit 59, and service battery 17 should also be considered as applicable to... Figures 11 to 18 The implementation shown is effective, in Figures 11 to 18 In the embodiments shown, these operating components / devices are not illustrated for the purpose of simplifying the drawings.
[0069] According to the invention, each battery 12, 12' is supported by a corresponding support 13, 13' that is movable between a retracted position and an extended (or withdrawn) position. Specifically, the first battery 12 is supported by a first support 13, and the second battery 12' is supported by a second support 13'. According to the invention, each support 13, 13' is operatively connected to a moving device 8, 8', which determines and / or releases rotation of the support 13, 13' itself about a corresponding rotation axis R, R', particularly rotation from the retracted position to the extended position.
[0070] Within the scope of this invention, the retracted position corresponds to a first compact and aerodynamic position with a reduced overall lateral dimension, while the extended (or withdrawn) position corresponds to a position that facilitates the removal of batteries 12, 12' for charging and subsequent repositioning of batteries 12, 12' in supports 13, 13'. Therefore, the moving device has the function of allowing batteries 12, 12' to be transferred from the first (retracted) position to the second (extended) position.
[0071] For the purposes of this invention, the terms "battery" and "battery pack" are considered synonymous and refer to a group comprising a plurality of battery cells inserted into a battery casing of any form. Preferably, at least one battery 12, 12' of the power assembly is lithium-type. Even more preferably, batteries 12, 12' are both lithium-type. However, it is also possible to provide a lithium battery and a battery of a different type, such as a lead / acid battery.
[0072] As mentioned above, Figures 1 to 10 This relates to a first embodiment of a vehicle according to the invention. Figure 2 , Figure 3 and Figure 4 In this study, it can be observed that the frame 2, according to well-known solutions, also supports a saddle (not shown), and therefore has a possible, and therefore non-exclusive, configuration. The configuration of the frame 2 is irrelevant to the purpose of this invention and can therefore be of any known type. In this respect, in the case of hybrid propulsion, the frame 2 can also support a tank.
[0073] In any case, as indicated above, for the frame 2, a front portion 2A and a rear portion 2C can be identified. The front portion 2A is pivotally associated with the steering assembly 4, and the rear portion 2C supports the saddle, and the fork 99 and therefore the drive wheel 9 are also pivotally associated with the rear portion 2C. The central portion 2B of the frame 2 extends between the two portions 2A and 2C as a bridge, thus acting as a connector and supporting the foot pedals (see [link]). Figure 4 ).
[0074] exist Figures 1 to 10 In the illustrated embodiment, the rear portion 2C includes a first frame side portion 21C and a second frame side portion 22C, which extend on the right and left sides respectively relative to the central plane AA. The two sides 21C and 22C are connected to each other by lateral elements 23C, 23D, and 23E, which are spaced apart from each other to establish their positions relative to the central plane AA. Therefore, a space is defined between the two sides 21C and 22C, in which the charger unit 50, the service battery 17, and the control unit 59 are housed.
[0075] In the embodiment illustrated in the accompanying drawings, the end portions 221C, 222C of the two side portions 21C, 22C (i.e., the portions furthest from the front end portion 3) extend on a plane substantially parallel to the support plane PO of the motor vehicle 1, wherein the orientation of this plane is considered when the vehicle is unloaded (see...). Figure 4 ).
[0076] The rear portion 2C of the frame 2 includes an upper element 26C, which has an inverted U-shaped configuration (see...). Figure 5 and Figure 6 The upper element 26C extends above the two side portions 21C and 22C (i.e., along the normal direction N). The upper element 26C externally connects the two side portions 21C and 22C near the beginning of the end portions 221C and 222C. (As in...) Figure 1 and Figure 4 As can be seen, the end portions 221C, 222C and the upper element 26C as a whole define a rear space 81 for positioning a load or load holding compartment.
[0077] Figures 1 to 10 The motor vehicle 1 shown in the figure also has a front frame 82A, which is associated with the front end portion 3 and supported by the front portion 2A of the frame 2, thereby defining another front space 82 for positioning another load or another load holding compartment.
[0078] In the preferred embodiment shown in the accompanying drawings, two batteries 12, 12' are mounted on a battery retainer frame, which includes a first lateral portion 71 connected to a first side portion 21C and a second lateral portion 72 connected to a second side portion 22C. The two lateral portions 71, 72 are positioned relative to a central plane AA (see Figure 1). Figure 5 ) mirror arrangement, and through the laterally extended lateral portion 73 ( Figure 8 (As can be seen) interconnected. For example, in Figure 5 As can be seen, the lateral portions 71 and 72 of the battery retainer frame 70 are preferably arranged outside the sides 21C and 22C of the rear portion 2C of the frame 2. In essence, the two lateral portions 71 and 72 are located outside the space defined between the two sides 21C and 22C.
[0079] The first support member 13 of the first battery 12 is hinged to the first lateral portion 71, while the second support member 13' of the second battery 12' is hinged to the second lateral portion 72. Specifically, each support member 13, 13' is preferably hinged to support elements 71A, 72A (of the corresponding lateral portions 71, 72), and the support elements 71A, 72A are rigidly connected to the corresponding lateral portions 71, 72 (see [reference]). Figure 10 Preferably, the support elements 71A, 72A are configured to define the ends of the travel surfaces 71B, 72B for the opening movement of the corresponding support members 13, 13'.
[0080] Figure 9 and Figure 10 The cross-sectional views allow for observation of the above solution. These figures show the solutions in their retracted positions ( Figure 10 ) and the position of the extension ( Figure 9 The support members 13, 13' and the corresponding batteries 12, 12' are shown. The opening movement of each support member 13, 13' can be observed. Figure 10 The amplitude of the arrow W in the diagram is established by the corresponding ends of the travel surfaces 71B and 72B.
[0081] According to the present invention, the support members 13, 13' include an internal hollow body, that is, defining a cavity for receiving the corresponding battery 12, 12'. Therefore, the shape of the cavity is at least partially geometrically conjugate to the shape of the corresponding battery 12, 12'. In the embodiment shown in the figures, the support members 13, 13' have a prism configuration extending from the base 130, 130', the outer sides of which are hinged to the battery retainer frames 71-72 (see figure). Figure 10 The corresponding lateral portions 71 and 72 are integrated into support elements 71A and 71B.
[0082] In this respect, the bases 130, 130' of each support member 13, 13' can be hinged to the corresponding support elements 71A, 71B in the central position, such that the volume of the relevant support member 13, 13' considered in the retracted position is equally bisected relative to the reference planes BB, B-B' parallel to the central plane AA and containing the corresponding axes of rotation R, R' (see...). Figure 5 Alternatively, each support member 13, 13' may be hinged in an eccentric position, such that the volume of the relevant support member 13, 13' considered in the retracted position is divided into an inner portion and an outer portion relative to the reference plane BB, BB, wherein the outer portion is larger than the inner portion. In this way, the weight of the support member 13, 13' is offset outward, thereby facilitating its movement toward the extended position.
[0083] According to a preferred embodiment, the rotation axes R, R' are preferably defined such that at least half of the volume of the relevant supports 13, 13' considered in the retracted position is included in the space between the central plane AA and the corresponding reference planes BB, B'-B' defined above. (As in combination from...) Figure 5 and Figure 7 As can be observed, this solution allows for a reduction in the overall lateral dimension associated with the two batteries 12, 12'. In this regard, it can be observed how, in the retracted position, the two batteries 12, 12' are positioned on opposite sides of the center plane AA adjacent to the shock absorber 44, i.e., in an inward position relative to the two sides 21°, 22°.
[0084] According to a first possible embodiment, as can be seen in the accompanying drawings, the moving device includes a coupling / disengagement system 8 comprising at least one first coupling element 15 integral with the rear portion 2C of the frame 2. The first coupling element 15 removably engages with a second coupling element 16 integral with at least one support member 13, 13' to lock the support members 13, 13' and thus the batteries 12, 12' housed within them in a retracted position. After the two elements 15, 16 are disengaged, the respective support members 13, 13' are allowed to rotate freely about corresponding axes of rotation R, R', thereby allowing the batteries 12, 12' to reach an extended position.
[0085] according to Figure 7 and Figure 8 In the embodiment shown, for each of the batteries 12, 12', the connection / disconnection system includes a first connection element 15 integrated with the frame 2 and a second connection element 16 integrated with the corresponding support member 13, 13'. Each first connection element 15 and the second connection element 16 are removably engaged to lock the corresponding support member 13, 13', and thus the battery 12, 12' housed in the corresponding support member 13, 13', in a retracted position. Therefore, the possible embodiment shown in the figures generally provides two first connection elements 15 and two second connection elements 16, with the two first connection elements 15 arranged on opposite sides and mirror-arranged relative to the center plane AA, and each second connection element 16 integrated with the corresponding support member 13, 13'.
[0086] In any case, the coupling / discoupling system includes a control unit (manually and electrically actuated) that determines the disengagement of each first coupling element 15 with its corresponding second coupling element 16. Specifically, the control unit determines the movement of each first element 15 between two operating positions, each representing an engagement / disengagement state with its corresponding second coupling element 16.
[0087] Reference Figure 7 and Figure 8 In the retracted position, each first connecting element 15 remains engaged with the corresponding second connecting element 16, thereby preventing the corresponding supports 13, 13' and associated batteries 12, 12' from rotating around their respective axes of rotation R, R'. Figure 7 The rotation of the first connecting element 15 (in the case of the second connecting element 16) allows the two supports 13, 13' to rotate freely about their respective axes of rotation R, R', so as to bring the two batteries 12, 12' to the removal position.
[0088] In a possible implementation, the control unit selectively acts on the two first coupling elements 15, i.e., to release each support 13, 13' independently of each other. Thus, one battery 12, 12' can be rotated from the retracted position to the extended position, while the other battery 12, 12' remains in the retracted position.
[0089] In an alternative configuration, the control unit is configured to simultaneously intervene in the first coupling element 15, i.e., to simultaneously disconnect / unconnect both from the corresponding second coupling element 16.
[0090] In an alternative configuration, the control unit may be configured to include the two indicated operating modes, allowing batteries 12 and 12' to be released simultaneously or not simultaneously.
[0091] In the embodiment shown in the accompanying drawings, the connection / disconnection system is conceptually constructed as a "latch-type" lock. In fact, the two first connection elements 15 consist of pin bodies, while the second connection element 16 includes a pair of U-shaped brackets integral with the inner sides of the corresponding supports 13, 13'. Each bracket defines a cavity into which the corresponding pin body snaps into, thereby locking the corresponding supports 13, 13' when they reach the retracted position. Upon activation, the control unit moves the pin body, thereby releasing the rotation of the supports 13, 13'.
[0092] In the embodiment shown in the accompanying drawings, the control unit is manually operated and includes a pair of levers 19 arranged in the area below the saddle 7 (see Figure 1). Figure 4 These rods 19 are mechanically connected to the first connecting element 15 (e.g., via Bowden cables) to cause movement of the first connecting element 15.
[0093] Preferably, the control unit is also provided with an electrically operated release device. In this case, the movement of the two first connecting elements 15 is generated by a device (such as a push button) that can be activated by the rider and positioned, for example, on the handlebars or rear guard of the motor vehicle 1.
[0094] According to the preferred embodiment shown in the accompanying drawings, the moving device of batteries 12, 12' includes a damper element 88, which functions to control the rotational speed of the support 13 and dampen the impact on the support 13 at least at the end of the stroke, i.e., at least in the final stage of the movement from the retracted position to the extended position. These damper elements 88 may be gas springs, hydraulic dampers, or other types of dampers, and have the function of controlling the rotational speed of the support 13 and damping the impact on the support 13 at the end of the stroke.
[0095] In the embodiment shown in the accompanying drawings, the damper element 88 includes a pair of gas springs, each gas spring intervening in a corresponding support member 13, 13'. Specifically, for each spring, a first end is connected to one of the two supports 13, 13', while a second end opposite to the first end is connected to the rear portion 2C of the frame. More precisely, in the illustrated solution, the second end of the gas spring is connected to elements of the corresponding lateral portions 71, 72 of the battery retainer frame. However, the second end can be connected to any other point on the frame 2, such as to sides 21C, 22C.
[0096] According to a preferred embodiment of the invention, the motor vehicle 1 includes a safety device configured to guide the movement of batteries 12, 12' from a retracted position to an extended position. The term "guide" indicates that this means triggering or facilitating the movement of supports 13, 13' toward the extended position after they have been released by the control unit.
[0097] Preferably, the safety device is also configured to apply a locking action to each battery 13, 13' to stabilize the batteries 13, 13' within the respective supports 13, 13' during forward movement of the motor vehicle 1.
[0098] In the embodiment shown in the accompanying drawings, the safety device includes a pair of rods L1, L2, which are substantially L-shaped and hinged to elements of the frame 2 near the central plane. The two rods L1, L2 are mounted in a mirror position relative to the central plane AA, such that for each rod, the longer side remains closer to the central plane AA and the shorter side extends away from it. This arrangement allows the ends L11, L21 of the longer sides to contact the inner side of the corresponding supports 13, 13' or batteries 12, 12', and the ends L12, L22 of the shorter sides to contact the upper side of one of the batteries 12, 12'. Each rod L1, L2 is acted upon by an elastic device (not visible in the drawings) that tends to rotate the rods L1, L2 in a direction that, for example, pushes the corresponding supports 13, 13' and the ends L11, L21 of the longer sides towards an extended position.
[0099] Figure 9Two batteries 12, 12' in the retracted position are shown, allowing observation of the arrangement of the two levers L1, L2 and their centers of rotation C1, C2. After manual application of force (arrow F), each battery 12, 12' rotates about its corresponding axis of rotation R, R' toward the retracted position. Following this rotation, for each battery 12, 12', the inner surface of the corresponding support 13, 13' (or the battery 12, 12' itself) contacts the longer side end L11, L21 of the corresponding lever L1, L2, thus determining its rotation in the opposite direction to the support itself. This rotation continues until the battery 12, 12' has completed its rotation, i.e., until the two supports 13, 13' are locked in the retracted position. In this case, for each lever L1, L2, the shorter side end L12, L22 acts on the upper surface of the corresponding battery 12, 12', thereby pushing the corresponding battery 12, 12' toward the axis of rotation R, R'. The thrust stabilized the position of batteries 12 and 12' inside the corresponding supports 13 and 13'.
[0100] When the two supports 13, 13' are disconnected (simultaneously or not simultaneously, as indicated above), due to the elastic mechanism acting on the two rods L1, L2, each rod applies a lateral thrust to the batteries 12, 12' through its longer end L1l, L21. This thrust ensures that the batteries 12, 12' are triggered to rotate toward the extended position. In other words, the action of the two rods 13, 13' is to complete the action of connecting / disconnecting the connection system and the trigger, or in any case, to facilitate the execution of the opening movement of the batteries 12, 12'. In this respect, the movement could also be triggered solely by gravity. However, the action of the rods L1, L2 ensures its execution.
[0101] Figures 11 to 18 This relates to a second embodiment of the motor vehicle 1 according to the present invention, which differs from the first embodiment described above. Figures 1 to 10 The differences are mainly due to the different configurations of the moving device 8' of the support members 13 and 13', and the different orientations of the rotation axes R and R' of the support members themselves.
[0102] In fact, in this second embodiment, the support members 13, 13' rotate about the rotation axes R, R', which are parallel to the central plane AA and orthogonal to the rotation axis of the rear wheel 9. In other words, in this case, the rotation axes R, R' are parallel to the longitudinal direction L defined above.
[0103] In this second embodiment, the moving device determines that the two supports 13, 13' rotate simultaneously, such that both supports 13, 13' are either in a retracted position or both are in an extended position. A single activation of the moving device causes at least one rotation of the two batteries 12, 12', which is suitable for simplifying removal from the support elements 13, 13' (moving from the retracted position to the removed position).
[0104] like Figures 13 to 16 As can be seen, the moving device 8' includes an actuator 77 acting on a pair of rods 14, 14'. Each rod 14, 14' has a first end 14A that engages with a corresponding support 13, 13' and a second end that is fixed to a common pin 15. Preferably, the rods 14, 14' are positioned at one end of the support 13, 13' near the central plane AA.
[0105] according to Figures 11 to 18 In the embodiment illustrated, the pin 15 hinged to the rods 14, 14' can be moved vertically in the longitudinal center plane AA of the vehicle 1 by means of the actuator 77. The actuator 77 determines the movement of the supports 13, 13' of the batteries 12, 12' toward the extended position or toward the retracted position by controlling the movement of the pin 15 in the normal direction N and thus controlling the upward or downward translation of the pin 15.
[0106] As in Figure 14 and Figure 15 As can be easily seen, pin 15 moves along worm 18, which acts as a guide for pin 15. The downward translation of pin 15 on worm 18 causes rods 14 and 14' to close, thereby moving supports 13 and 13' to a retracted position, i.e., to an arrangement such that supports 13 and 13' are parallel to the longitudinal center plane AA and mirrored relative to it. The upward translation of pin 15, again determined by actuator 77, causes rods 14 and 14' to open, which in turn move supports 13 and 13' to an extended position. Figure 12 and Figure 18 As can be seen, in this position, the supports 13, 13' are inclined relative to the longitudinal center plane AA, and the upper ends of the supports 13, 13' are exposed and therefore easily accessible. According to the purpose of the invention, in this position, the removal and repositioning of the batteries 12, 12' is very simple.
[0107] Actuator 77 can be of any known type, such as an electric actuator, an electrostatic actuator, an electromagnetic actuator, or a hydraulic actuator. Nevertheless, according to a preferred embodiment, actuator 77 is of an electric type and is operated by service battery 17, preferably the same as the service battery used to start vehicle 1.
[0108] In the embodiment shown in the accompanying drawings, actuator 77 controls the movement from the retracted position to the extended position and the reverse movement (from the extended position to the retracted position). Nevertheless, actuators configured to only ensure the opening movement (from the retracted position to the extended position) of supports 13, 13' can be used, while the reverse closing movement can be manually performed.
[0109] Alternatively, an actuator can be provided to control the closing movement (from the extended position to the retracted position), depending on the... Figures 1 to 10 The principle of the solution shown above is similar to that described above; the opening movement can be achieved by means of gravity. In this respect, and also in this case, this can be achieved by safety devices, such as the previously described safety devices (bars L1, L2) or other functionally equivalent devices.
[0110] Similarly, in this second embodiment, the moving device may include a damping element suitable for controlling the rotational speed of the supports 13, 13'. Figures 11 to 18 (Not shown in the figure). In particular, these damping elements are useful when the actuator 77 is configured to function only during the closed period, i.e., to actuate movement toward the retracted position, while the opposite movement is actuated by gravity.
[0111] In any case, for any possible configuration, the actuator 77 is controlled by a control device advantageously located at the front end portion 3, preferably on the handlebars or the rear fairing. Nevertheless, the control device may also be located elsewhere, such as in the saddle compartment.
[0112] Refer again Figures 11 to 18 In this second embodiment, the rear portion 2C of the frame 2 is also partially different. Figures 1 to 10 The rear portion is shown. Specifically, the lateral portions 711 and 712 of the battery retainer frame have different configurations. In this configuration, a pair of lateral portions 711 and 712 can still be found, each of which extends below the corresponding side portions 21C and 22C, thus having at least one straight length extending in a longitudinal direction orthogonal to the central plane (considering the vehicle being unloaded and placed on the horizontal plane PO). The corresponding supports 13 and 13' of the batteries 12 and 12' are hinged to this straight length to configure the rotation axes R and R'.
[0113] As can be seen, for example, from the accompanying drawings, the rear portion 2C also includes a central element 29 that extends across the center plane AA, and the two lateral portions 711, 712 of the frame 2 are connected to this central element 29 at the rear. The two lateral portions 711, 712 are also connected above and at the front to the corresponding sides 21C, 22C. Figure 15As can be seen, the fork-shaped part 99 is connected to the rear end of the central element 29. Figure 15 The axis of rotation X of the fork-shaped component is indicated in the text. Columns 24A and 24B (in...) Figure 16 (As shown in the diagram) The central element 29 is arranged between the lateral elements 23D and 23E in the rear portion 2C of the frame, separating the side portions 21C and 22C from the central element 29 itself at the top. Figure 16 As can be seen, the shock absorber 44 is positioned between the rear pillar 24B and the fork-shaped component 99. The front pillar 24A is instead positioned in the central portion 2B of the frame 2. Figure 16 In order to highlight the structure of the moving device of the support members 13 and 13', the support members 13 and 13' are not shown.
[0114] Regarding other parts of the motor vehicle 1, such as the power system 110, the charging unit of the batteries 12, 12' and / or the control unit 59 of the electric motor 111, the description provided above for the first embodiment should be considered valid.
[0115] In the described embodiment and as can be seen in the accompanying drawings, the batteries 12, 12' and the corresponding supports 13, 13' are preferably positioned at the rear end portion 6, inserted between the saddle 7 and the drive wheel 9. However, depending on the configuration of the frame 2 and the overall configuration of the motor vehicle 1, the batteries 12, 12' and the corresponding supports 13, 13' can also be positioned in another location, for example, in the middle portion 10 below the foot pedal.
[0116] In any case, and regardless of the implementation of the motor vehicle 1, the batteries 12, 12' are preferably provided with clamping devices 119, 119' adapted to facilitate the removal of the batteries 12, 12' from the respective supports 13, 13'.
[0117] Preferably, each battery 12, 12' is provided with a removable locking strap 114, 114', the ends of which can be fixed to the opposite wall of the associated support 13, 13'. Each strap 114, 114' is fixed so as to act on the upper surface of the battery 12, 12', thereby applying a force to stabilize the housing of the battery 12, 12' in the associated support 13, 13'.
[0118] In all the embodiments described and shown, the control unit 59 includes a plurality of electrical / electronic components arranged inside a metal container. In the case of a hybrid power system 110, traction is ensured by energy stored in batteries 12, 12' that power the electric motor 111, and the batteries 12, 12' can be charged either by connecting the batteries 12, 12' to a power source and / or to a specific mainline power source with a standard socket, or by means of a motor generator, i.e., a heat-absorbing motor, which operates a generator arranged to charge the batteries 12, 12' and / or power the power system 110.
[0119] In addition, an intermediate solution can be provided in which a portion of the electrical energy generated by the generator is used directly for traction, while another portion is used to increase the available power in batteries 12 and 12'.
[0120] In the presence of a 220V power outlet, such as in a garage, batteries 12 and 12' can be charged even without being removed. This can be achieved via the aforementioned charger unit 51 located below the saddle 7 and using a cable with an electrical connector 52 (socket) at its end. When not in use, the socket remains positioned in a specific seat defined within the saddle compartment. Preferably, when the socket is still in use, for example because it is connected to the main power grid or if it has been disconnected but not yet repositioned in the seat, starting the vehicle 1 is prohibited by the control unit 59.
[0121] Conversely, if the socket is located in the seat, the saddle 7 can be completely closed, allowing the vehicle 1 to be started under safe conditions. In this configuration, the cable is completely contained within a housing shaped to accommodate the available space at the rear wall of the helmet compartment.
[0122] The possible operating mode of the driver of the motor vehicle 1 in the described second embodiment, and when the batteries 12, 12' are partially or fully charged, will now be described. After determining that charging is required by a suitable indicator device, and after stopping the vehicle, the driver operates the control device, for example, by pressing a button located on the handlebar 17 or by operating a lever. The control device activates actuator 77, which moves the supports 13, 13' toward the extended position. When this position is reached, the batteries 12, 12' are easily accessible, and the driver can remove the batteries 12, 12' by simply using the associated clamping devices 119, 119'. This operation requires no tools and poses no risk of contamination or injury. After charging is complete, the driver inserts the batteries 12, 12' into the associated supports 13, 13' and rotates the supports 13, 13' toward the retracted position via the control device, thereby allowing the vehicle 1 to once again optimize its aerodynamic configuration for driving.
[0123] When the moving device is configured according to the first embodiment described above, the movement of the support members toward the removal position occurs after the initiation of the rotation of the battery release system after disconnection. This rotation is ensured by the safety devices (lever L1, L2) indicated above, but can also occur solely by gravity. In this case, the return of the support members 13, 13' to the retracted position is achieved through manual intervention by the driver.
[0124] As shown, the above-described technical solution allows for the full realization of the set goals and objectives. Specifically, the positioning of batteries 12, 12' and associated supports 13, 13', together with the mobility of supports 13, 13' and the presence of associated moving parts, enables simple and quick operations for removing and installing batteries 12, 12', while ensuring adequate driving autonomy and reducing the size of vehicle 1.
[0125] The saddle-type vehicle 1 conceived thus is susceptible to a variety of possible variations, all of which fall within the scope of the invention. In this regard, in possible variations, the vehicle may include a coupling system 8 similar to that shown in the first embodiment, and also includes an actuating device 77 for performing rotation of the supports 13, 13' in both directions after the coupling / disconnection system releases the supports 13, 13' to the retracted position.
[0126] Generally speaking, the materials used, as well as the size and form of accessories, can be arbitrary, depending on the needs and existing technology.
