Abstract
A mechanism includes a first component, a second component and a biasing assembly. The first component and a second component are configured to attach a structure to a vehicle. The biasing assembly, which includes a biasing member, operatively connects the first component and the second component to one another. When a force is applied along a first direction on the first component, the biasing member biases the first component against the second component in a rest position to transfer the force from the first component to the second component. When the force is applied along a second direction on the first component, the second direction being opposite to the first direction, the biasing member absorbs at least a portion of the force in a loaded position.

As persons skilled in the art would understand, various embodiments of the present technology may be of a greater complexity than what is described herein.
[0050] The present disclosure is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the drawings. The disclosure is capable of other embodiments and of being practiced or of being carried out in various ways. Also, the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. The use of including, comprising, or having, containing, involving and variations thereof herein, is meant to encompass the items listed thereafter as well as, optionally, additional items. In the following description, the same numerical references refer to similar elements.
[0051] In the context of the present specification, unless expressly provided otherwise, the words first, second, third, etc. have been used as adjectives only for the purpose of allowing for distinction between the nouns that they modify from one another, and not for the purpose of describing any particular relationship between those nouns.
[0052] It must be noted that, as used in this specification and the appended claims, the singular form a, an and the include plural referents unless the context clearly dictates otherwise.
[0053] As used herein, the term about in the context of a given value or range refers to a value or range that is within 20%, preferably within 10%, and more preferably within 5% of the given value or range.
[0054] As used herein, the term and/or is to be taken as specific disclosure of each of the two specified features or components with or without the other.

[0055] For purposes of the present application, terms related to spatial orientation when referring to a structure and components in relation to the structure, such as vertical, horizontal, forwardly, rearwardly, left, right, above and below, are as they would be understood by a driver of a vehicle to which the structure is connected sitting thereon in an upright driving position, with the vehicle steered straight-ahead and being at rest on flat, level ground.
[0056] With reference to
[0057] Also, though the front bumper 100 shown in
[0058] With reference to
[0059] In this non-limiting example, the mounting system 20 comprises four mechanisms for connecting the bumper 100 to the body of the vehicle 10. However, this might not be the case in each and every embodiment of the present technology. For example, a given component and/or accessory of the vehicle 10 may be connected to the body of the vehicle 10 via a single, two, three or five or more mechanisms implemented similarly to the mechanism 200.
[0060] In this non-limiting example, the mechanisms 200, 200, 200, and 200 are configured to operate as resilient joints that can absorb a portion of shocks suffered by the bumper 100 during impacts, thus reducing the shocks transmitted to the vehicle 10. Thus, the mechanisms 200, 200, 200, and 200 may be referred to as shock-absorbing mechanisms. In this non-limiting example, the mechanisms 200, 200, 200, and 200 are configured to operate as rigid joints when the bumper 100 is used as a structural element for pulling loads by the vehicle 10 for example, thus providing an additional functionality to the vehicle 10 and/or to the user. In this non-limiting example, the mechanisms 200, 200, 200, and 200 are configured to operate as rigid joints in tension and as resilient joints in compression for the bumper 100 of the vehicle 10. However, it is contemplated that in some cases, the mechanisms 200, 200, 200, and 200 may be configured to operate as rigid joints in compression and as resilient joints in tension for a structure, component and/or accessory to be mounted on the vehicle 10.
[0061] With reference to
[0062] The mechanism 200 comprises a first component 301 and a second component 302. The first component 301 and the second component 302 are configured for attaching a given structure (such as the bumper 100) to a given vehicle (such as the vehicle 10). In this embodiment, the first component 301 is configured to be attached to the vehicle 10, while the second component 302 is configured to be attached to the bumper 100. It is contemplated that the first component 301 may be an integral portion of the vehicle 10 and/or that the second component may be an integral component of the bumper 100, without departing from the scope of the present technology.
[0063] The mechanism 200 also comprises a biasing assembly 303 operatively connecting the first component 301 and the second component 302 to one another. The biasing assembly 303 comprises a housing 306, a biasing member 310, and a connection assembly 304.
[0064] The housing 306 defines an elongated cavity 308 extending along an axis 360 of the biasing assembly 303. In this embodiment, the housing 306 is fixedly attached to the second component 302 while the connection assembly 304 is fixedly attached to the first component 301. However, it is contemplated that in some embodiments of the present technology, the housing 306 may be fixedly attached to the first component 301, while the connection assembly 304 may be fixedly attached to the second component 302.
[0065] The biasing member 310 is configured to be received in the elongated cavity 308. In some embodiments, the biasing member 310 can be made of a resilient material. In some embodiments, the resilient material is an elastomeric material. In some embodiments, the resilient material is polyurethane, elastomer, or rubber. In some embodiments, the biasing member 310 could be made of two or more material configured to obtain a desired composite shock absorption profile. The selection of resilient material may depend on, inter alia, a desired resiliency for the mechanism 200. However, it is contemplated that the biasing member 310 may be implemented via other biasing means such as but not limited to a spring member, a pneumatic member, and/or a hydraulic member. In further embodiments, the biasing member 310 may be implemented using a combination of materials and systems offering a biasing effect to return to an initial position and damping effect when compressed. It is contemplated that the biasing member 310 may be a frangible and/or a consumable biasing member configured to be replaced when the biasing member 310 absorbs a shock of a pre-determined magnitude.
[0066] In some cases, the biasing member 310 can be made of a material having a certain plasticity (i.e., with the ability to undergo permanent deformation) such that in response to being subjected to forces equal to or beyond a pre-determined magnitude, the biasing member 310 may undergo a non-reversible change of shape. In some other cases, the biasing member 310 can be shaped and configured so that a portion thereof irreversibly breaks in response to being subjected to a force equal to or beyond a pre-determined magnitude. In such cases, when the biasing member 310 is deformed in response to the application of a force equal to or beyond the pre-determined value, the deformed biasing member 310 can be replaced by a new biasing member 310 for optimal working conditions.
[0067] It is contemplated that biasing members having different rigidities can be provided for different shock absorption magnitudes. For example, some biasing members may be rated for low capacity, for medium capacity, or for high capacity based on their resiliency and their rigidity.
[0068] It is contemplated that in some embodiments, the biasing members may have to be changed periodically in accordance with a pre-determined schedule to ensure that their shock absorption properties meet a pre-determined specification.
[0069] The connection assembly 304 is configured to transfer forces between the first component 301 and the second component 302. To that end, at least a portion of the connection assembly 304 is received in the elongated cavity 308 of the housing 306.
[0070] In this embodiment, the connection assembly 304 comprises a fastener 314, a sleeve 312, a retainer 315, and a nut 313. The sleeve 312 is configured to accommodate the fastener 314 and is receivable in the elongated cavity 308. The fastener 314 is configured to cooperate with the nut 313 and the retainer 315 to retain the sleeve 312 in the elongated cavity 308. The fastener 314 is also configured to cooperate with the nut 313 and the retainer 315 to be selectively fixedly attached to the second component 302. The fastener 314 is also configured to cooperate with the nut 313 and the retainer 315 to selectively movably connect the second component 302 to the housing 306. In other words, the second component 302 may move relative to the housing 306 as the sleeve 312 moves along the elongated cavity 308.
[0071] Although in this embodiment, the connection assembly 304 is selectively fixedly attached to the second component 302, this may not be the case in each and every embodiment. In other embodiments, it is contemplated that the connection assembly 304 may be a pivoting connection assembly, which not only allows movement of the second component 302 relative to the housing 306 along the axis 360, but also allows a pivoting movement of the second component 302 about the axis 360 and/or about an other axis. As schematically illustrated in
[0072] It can be said that a given connection assembly may serve as a pivot between the first component 301 and second component 302, so that a relative pivoting movement between the first component 301 and second component 302 is permissible via the pivot. However, the relative pivoting movement between the first component 301 and second component 302 may be prohibited via a non-pivoting connection assembly, so as to allow only a translational movement along the axis 360.
[0073] With reference to
[0074] As seen in
[0075] As seen in
[0076] As seen in
[0077] When the mechanism 200 is in the loaded position, the biasing member 310 biases the connection assembly 304 toward its initial position (i.e., rest position). When the external force 390 is less than the biasing force provided by the biasing member 310, the connection assembly 304 moves toward its initial position.
[0078] Referring to
[0079] Referring to
[0080] With reference to
[0081] In this embodiment, in response to an external force being applied on the monobloc bumper 500, and the external force being oriented towards the given vehicle body, the mechanisms 501 and 501 provide a biasing connection between the monobloc bumper 500 and the given vehicle. The biasing connection provides a shock absorbing functionality for the monobloc bumper 500 and allows translational movement of the monobloc bumper 500 relative to the given vehicle.
[0082] In this embodiment, in response to an external force being applied on the monobloc bumper 500, and the external force being oriented away from the given vehicle body, the mechanisms 501 and 501 provide a fixed connection between the monobloc bumper 500 and the given vehicle. The fixed connection provides a second functionality for the monobloc bumper 500 by preventing translational movement of the monobloc bumper 500 relative to the given vehicle. In one non-limiting example, the monobloc bumper 500 may function as a winching structure for the given vehicle without damaging the shock absorbing functionality of the monobloc bumper 500. In this embodiment, it is understood that the monobloc bumper 500 moves relative to the vehicle body to which it is connected via the mechanisms 501 and 501 along at least one translational axis. In some cases, the monobloc bumper 500 may move relative to the vehicle body to which it is connected via the mechanisms 501 and 501 along at least one pivotal axis as well.
[0083] With reference to
[0084] In this embodiment, the mechanisms 601, 601, 601, and 601 may provide a fixed connection between respective sub-structures in response to forces applied in a first direction, and a biasing connection between respective sub-structures in response to forces applied in a second opposite direction. In this embodiment, the mechanisms 601, 601, 601, and 601 comprise pivoting connection assemblies allowing for a pivoting motion between respective sub-structures, without departing from the scope of the present technology.
[0085] Although in this embodiment, the central sub-structure 610 is fixedly attached to the given vehicle, this might not be the case in each and every embodiment of the flexible bumper 600. In other embodiments, the flexible bumper 600 may be selectively attached to the given vehicle using the mounting system 50 (see
[0086] It should be noted that the front and rear bumpers of vehicles such as ATVs, side-by-side vehicles, and snowmobiles are protective components designed to absorb impacts and reduce damage to the vehicle and/or injuries to the user thereof during collisions or encounters with obstacles. Bumpers provide a first line of defense, safeguarding both the vehicle and its occupants. Mounting systems in accordance with the present technology can allow a dual-functionality connection which operates, depending on an external force applied thereto, as a biasing connection for shock absorption or a rigid connection for added structural support. However, other structures than bumpers may benefit from one or more mounting systems and/or one or more mechanisms described herein.

[0088] With reference to
[0089] With reference to
[0090] With reference to
[0091] It is contemplated that non-limiting examples of structures connectable to vehicles described above may share a common function of providing protection to various parts of the vehicle. In many cases, these structures may benefit from the use of both biasing connection and rigid connection depending on external forces applied thereto. A biasing connection is desirable when shock absorption and/or flexibility is required to protect the vehicle from impacts and vibrations. Conversely, a rigid connection is useful when strength, stability, and/or precise control is desirable, such as during winching, for example. Enabling two different types of connections allows these structures to effectively perform their protective functions while enhancing the overall durability and performance of the vehicle.
[0092] It is contemplated that the mechanism described herein may be used to connect an accessory to a vehicle body and/or to a structure (e.g. bumper). This may assist in preventing damage to the accessory during an impact.
[0093] Modifications and improvements to the above-described embodiments of the present technology may become apparent to those skilled in the art. The above description is intended to be exemplary rather than limiting.
