Description

Technical Field

[0001] This application generally relates to providing a two-part rigid fixation and a mounting system having such fixation for mounting electronic devices or electronic modules into a vehicle. Background Technology

[0002] In modern vehicle architectures, mounting brackets or frames are often required for installing electronic devices or modules. To mount electronic devices into the vehicle, brackets are provided to hold them in place. Some electronic devices or modules have their own housings and mounting features. To integrate these devices into the vehicle, some current arrangements require a two-piece bracket system. This typically consists of a plastic bracket to hold the device and a metal bracket that is secured to the vehicle. These two brackets can be mated using alignment screws and additional fixing points. The mating between the plastic bracket holding the electronic device and the metal bracket screwed to the vehicle can use steel pins. This arrangement has several disadvantages, including cost and overhead, and it is often over-designed. Arrangements using steel pins can also generate noise due to vibration due to their design. Therefore, it is necessary to provide an alternative mating arrangement to overcome the above-mentioned shortcomings of current arrangements used for mounting electronic devices or modules into vehicles. Summary of the Invention

[0003] The system is provided as defined below. Further optional features are provided depending on other aspects.

[0004] According to this specification, an installation system is provided, configured to install electronic devices or electronic modules into a vehicle, the installation system comprising:

[0005] Base mounting plate;

[0006] A device support plate for supporting the electronic device; and

[0007] At least one fastening element is provided for securing the device support plate to the base mounting plate;

[0008] The base mounting plate includes at least one bracket for connection with the device support plate;

[0009] The device support plate includes at least one connector, each connector being defined by a wall arranged about a central longitudinal axis, the wall of the connector including a plurality of resilient wall portions, the inner peripheral surface of the wall including an axially extending channel defining a receiver for receiving the fastening element.

[0010] Each fastening element includes at least two engaging members, each engaging member including an outer peripheral surface defining a mating surface for contacting a corresponding mating surface of the receiver; wherein each engaging member is configured to apply a corresponding control force to the corresponding mating surface of the receiver, the control force displacing the plurality of resilient wall portions of the receiver, thereby engaging the wall of the connector with a corresponding bracket of the base mounting plate to fasten the base mounting plate to the device support plate.

[0011] According to the arrangement described in this specification, the mounting system provides a secure and robust attachment between the mounting plate and the device support plate, and mounts electronic devices or modules to the vehicle. This arrangement addresses the problems of previous methods. The fastening elements and the connector receivers are formed to be compatible, and a controlled force is provided between them based on their interaction. The connector is flexible. When a portion of the connector wall shifts due to the force applied by the fastening elements, it flexes and engages more tightly with the corresponding engagement portion of the base mounting plate. The interaction provided in multiple areas effectively secures the connection. The application of controlled forces (including in the axial and radial directions) provides flexure and bending, and torque and the force generated by torque provide tightening and rigidity.

[0012] According to one aspect, the base mounting plate includes at least one bracket for connection with the device support plate; and a corresponding connector of the device support plate includes a bracket connector member for connection with the base mounting plate at the bracket.

[0013] The connector of the device support plate includes a bracket connector member recessed into the outer peripheral surface of the connector wall and a receiver formed to extend through the inner peripheral surface of the wall. Therefore, the connector is firstly a common component for the connection of the connector and the bracket, and secondly a common component for the connection of the connector and the fastening element. This provides a compact common connection and supports the interaction of all three components at each connection joint.

[0014] According to another aspect, the bracket connector component includes a circumferential channel formed recessed relative to the outer peripheral surface of the wall of the connector; and wherein the bracket and the bracket connector component are formed and sized such that a portion of the bracket can be received within the circumferential channel when the connector snaps into the bracket.

[0015] The bracket and connector are configured for a two-step connection. In the initial step, the bracket and connector are engaged via a snap-fit ​​mechanism. The base mounting plate is relatively rigid, and the connector on the device support plate is configured to allow flexibility. The mating between the two plates is defined by the bracket, connector, and fastening element. When the fastening element is pushed into the flexible connector, the connector walls effectively unfold or expand accordingly, and the flexible connector moves against the more rigid bracket at the bracket connector members and channels.

[0016] In one arrangement, the connector and the bracket are configured to be connected in a direction orthogonal to the central longitudinal axis of the connector, and the fastening element and the connector are configured to be connected in the direction of the central longitudinal axis, wherein when engaged, the fastening element and the connector, as well as the bracket and the bracket connector member, are all arranged concentrically about the central longitudinal axis of the connector.

[0017] This mounting system is based on the three-dimensional interaction of concentrically connected components configured to provide controlled forces through their interaction, acting between them to secure the mounting by interlocking the connection features. The controlled forces are provided by the direct interaction of the fastening element and the receiver of the connector, and the connector wall flexes and bends in a generally radially outward direction to tighten and secure the bracket connector assembly within the bracket. Tightening provides interlocking of the bracket within the bracket connector assembly. The engagement between the fastening element and the receiver is circumferential, as is the engagement between the bracket and the connector. With this circumferential connection, the board can still move about the axis of the connector or coupling to adjust the vertical angular alignment of the electronics.

[0018] According to the arrangement in the specification, the plurality of resilient wall portions are spaced apart by slots, and the wall portions and slots extend in the direction of the central longitudinal axis.

[0019] The walls of the connector are configured to be flexible or elastic by means of a portion of the wall configuration. The elasticity may also arise from the material properties of the walls. Therefore, the connection between the plates is also elastic. The fastening elements are also configured as expansion elements, and the outer peripheral surface of the mating member is configured to come into close contact with the corresponding opposing surface of the receiver, causing the latter to shift or flex.

[0020] In one arrangement, the plurality of resilient wall portions of the connector are displaced outward relative to the central longitudinal axis of the receiver.

[0021] The connector is configured to have a degree of flexibility. Forces generated by the interaction between the fastening element and the receiver provide flexure and bending of the connector walls. These forces include forces generally pointing outwards relative to the central axis of the connection. These forces, including forces near the proximal end of the receiver, also provide torque and bending of the connector.

[0022] According to another arrangement, each fastening element and its corresponding receiver includes a matching engagement feature for controlling the force between the fastening element and the receiver during engagement, wherein the force generated by the interaction between the fastening element and the receiver includes forces F3 and F4 acting to hold the fastening element in the receiver in opposite axial directions X.

[0023] The fastening element and the connector receiver are configured to conform and provide controlled forces based on their interaction, including forces in the axial direction. The relative forces in the axial direction generated by the interaction of the fastening elements in a predetermined position act to retain the fastening element in the receiver and resist pull-out.

[0024] In another arrangement, the force generated by the interaction of the fastening element and the receiver includes a force provided in a generally radial direction relative to the central longitudinal axis and acting to displace the wall of the connector outward relative to the central longitudinal axis, thereby providing interlocking of the base mounting plate at the device support plate, at the connector, and at the bracket. This arrangement allows for flexure, bending, and tightening of the connection between the bracket and the channel.

[0025] The controlled forces are provided by the direct interaction between the fastening element and the receiver of the connector, and the deflection of the connector wall in the radially outward direction, to tighten and secure the bracket connector assembly within the bracket. These forces are further configured to be circumferentially outward.

[0026] In one arrangement, the fastening element includes: an elongated body extending from a head at a proximal end to a tip at a distal end; a first engaging member having a generally spherical or oval body, wherein the mating surface of the fastening element is configured to engage in a retainer of the receiver; and a second engaging member having a generally cylindrical body, wherein the first engaging member and the second engaging member are circumferentially engaged with the receiver at axially spaced locations during use.

[0027] In the embodiments described herein, the fastening element and the corresponding receiver are formed to mate and are each arranged to circumferentially engage at their peripheral surfaces. A portion of the fastening element has a radial extent that mates with the receiver. The mating surfaces are configured to clamp into contact when in the engaged position. The fastening element provided herein has portions in the form of spherical or oval shapes, as well as other portions in the form of cylindrical or conical cylinders. The mating surfaces defined by the outer peripheral surfaces of the first and second engaging members may be arranged obliquely relative to the central longitudinal axis of the fastening element. The corresponding portions of the inner peripheral surface of the receiver are also obliquely arranged for matement.

[0028] In another arrangement, the receiver includes a guide and a retainer, each of which is configured to engage with a corresponding engagement member of the fastening element, wherein the guide includes a tapered guide extending between the opening of the receiver and the retainer.

[0029] In another arrangement, the retainer includes:

[0030] A circumferential ridge, the circumferential ridge extending into the receiver relative to the inner circumferential surface; and

[0031] A recess is provided adjacent to the ridge, wherein the form of the retainer corresponds to the corresponding engagement member of the fastening element.

[0032] The receiver may include a retainer, such as a recess for retaining the fastening element. The form of the recess depends on the form of the corresponding engaging member of the fastener.

[0033] In one arrangement, the fastening element and the connector are configured such that the force between the features includes radial forces (F1 and F2) generated by the interaction of corresponding portions of the engagement member of the fastening element and the inner circumferential surface of the receiver, the radial forces being applied to the wall of the connector at axial positions on both sides of the channel to thereby provide tightening of the connection between the bracket and the channel.

[0034] In another arrangement, the bracket connector member and the channel are positioned near and outside the retainer of the receiver, the bracket connector member and the channel are formed in the outer peripheral surface of the connector, and the retainer is formed in the inner peripheral surface.

[0035] In one arrangement, the mounting system is configured such that the device support plate and the base mounting plate are configured to contact only at the connection between the bracket and the corresponding connector when coupled.

[0036] When connected and interlocked, the boards remain separated from each other, with the connection located between them. The connection is positioned at a flexible joint between the boards.

[0037] In another arrangement, the device support plate includes a first connector and a second connector configured to engage with corresponding first brackets and second brackets of the base mounting plate; wherein pairs of the first brackets and the first connectors, and pairs of the second brackets and the second connectors, are arranged to align about a common axis when engaged; and each connector and bracket is configured to allow one of the plates to rotate about the common axis relative to the other when engaged at the brackets and the connectors and when fastened with the fastening elements.

[0038] The mounting system arrangement allows for the tilting or rotation of one plate relative to another. The mounting system may further include connector and bracket pairs that are misaligned with another connector and bracket pair. In this configuration, the arrangement is static and does not support tilting when the plates are connected at the two misaligned connector and bracket pairs. Attached Figure Description

Detailed Implementation

[0051] The following discussion provides many exemplary embodiments of the subject matter of this invention. Although each embodiment represents a single combination of inventive elements, the subject matter of this invention is considered to include all possible combinations of the disclosed elements. Thus, if one embodiment includes elements A, B, and C, and a second embodiment includes elements B and D, then the subject matter of this invention is considered to include the remaining combinations of A, B, C, or D, even if not explicitly disclosed.

[0052] For simplicity and clarity of illustration, reference numerals may be repeated in the figures to indicate corresponding or similar elements. Numerous details are set forth to provide an understanding of the embodiments described herein. These embodiments may be practiced without these details. In other instances, well-known methods, procedures, and components have not been described in detail to avoid obscuring the described embodiments. This description should not be construed as limiting the scope of the embodiments described herein.

[0053] Figure 1 A common type of mounting system 100 is shown for mounting electronic components or modules to a vehicle. In the illustrated arrangement, two mounting members 120 and 130 are provided. One mounting member 130 is arranged to hold the electronics, while the other mounting member 120 is mounted to the vehicle using appropriate fastening means / devices. The mounting member 130 for holding the electronics is made of plastic, while the mounting member 120 for mounting to the vehicle is typically made of a rigid material (such as metal). Alignment screws 150 and additional fastening devices 140 are provided to mate, connect, and hold the two members together. There are several related issues with mounting electronics to a vehicle, including the tendency for this arrangement to generate noise due to vibration when used in a vehicle.

[0054] To overcome this drawback and provide an improved mounting system, an arrangement for mounting electronic devices or electronic modules into a vehicle according to this specification is provided.

[0055] refer to Figures 2a to 9 Exemplary mounting systems 200 and 1200, 4200 for mounting electronic devices into vehicles are described.

[0056] First refer to Figure 2a and Figure 2bThe mounting system 200 is described below. The mounting system 200 includes a first base mounting plate 201, a second device support plate 205, and a third fastening element 260. The base mounting plate 201 is configured for mounting to a vehicle V and for connecting the device support plate 205 to the vehicle. The device support plate 205 can be mounted to the base mounting plate 201 and is configured to receive and support an electronic device D. The mounting system 200 is essentially a three-part mounting system, wherein the fastening element is configured to secure the device support plate 205 to the base mounting plate 201.

[0057] In the illustrated arrangement, the base mounting plate 201 includes: a first surface 210 configured to face the vehicle (direction V) in use; and a second surface 211 configured to face the device (direction D) in use. The base mounting plate 201 extends longitudinally (in the X direction) between a first end 212 and a second end 213, which extend between an upper longitudinal side edge 215 and a lower longitudinal side edge 214 of the base mounting plate. The base mounting plate 201 is configured to be fixed to the vehicle. Fixing can be achieved by any suitable fixing device. The base mounting plate 201 is made of a material that provides rigidity. The base mounting plate can be made of a metallic material (e.g., aluminum or steel). However, it is understood that any suitable material with the required rigidity can be used. The base mounting plate 201 includes a first bracket and a second bracket 202. These brackets are configured for connection with corresponding components of a device support plate. Figure 2a , Figure 2b In the arrangement, the bracket 202 is positioned longitudinally spaced and extends outward from the second surface 211 of the base mounting plate (shown in the figure in an XY plane orientation) facing the device, and extends in a direction (Z) transverse to the second surface 211 of the facing device. The bracket 202 has a receiver 222 and arms 220, with an opening 221 defined between the arms. The receiver 222 of the bracket 202 is arranged about a central longitudinally extending axis 229 (extending in the X direction). The arms 220 are curved, and the cross-section of the receiver 222 is generally circular or C-shaped. The inner circumferential surface 223 of the arm 220 defines a mating surface for mating with a corresponding feature of the connector 206. The bracket is a rigid bracket. The bracket is integrally formed with the base mounting plate and is made of the same material. The bracket 202 can be formed at a cutout in the base mounting plate and can be shaped on this basis (e.g., see...). Figure 8a Alternatively, the bracket can be welded or bonded to the base mounting plate. The central axis 229 of the bracket 202 and the receiver 222 is substantially positioned parallel to the central longitudinal axis of the second surface 211 of the base mounting plate 201. Figure 2a , Figure 2bIn the exemplary arrangement, the bracket 202 further includes outer supports 227, 228, which extend laterally on the surface of the outer ends 213 and 212 of the base mounting plate relative to the base mounting plate. The first and second brackets 202 extend outwardly from the surface of the base mounting plate 201, and the outer supports 227, 228 of each bracket substantially extend the width of the base mounting plate at their base. The outer support 227 may be tapered inwardly relative to the base at the opening.

[0058] Therefore, in Figure 2a , Figure 2b In this arrangement, each receiver 222 is centered relative to the surface of the base mounting plate 201 and also centered relative to the bracket 202. This arrangement provides improved stability when mounting the plates to each other and when installing electronics into the vehicle.

[0059] The device support plate 205 includes: a first surface 230 configured to face the vehicle (direction V) in use; and a second surface 231 configured to face the device (direction D) in use. As shown, the support plate 205 extends longitudinally (in the X direction) between its first end 232 and second end 233 and between its upper longitudinal side 235 and lower longitudinal side 234. Similar to the base mounting plate 201, the surfaces of the support plate 205 are arranged in an XY plane orientation (orientation of use) as shown in the exemplary arrangement illustrated in the figure. In use, electronic devices or electronic housings can be coupled to the device support plate to mount the electronic devices or electronic housings to the vehicle via a mounting system.

[0060] The support plate 205 includes a first connector and a second connector 206. Connector 206 is configured to provide a connection between the support plate 205 and the base mounting plate 201 at a bracket 202. The connector 206 and the bracket 202 are formed to mate and have corresponding mating features configured to interact to facilitate engagement of the connector of the support plate with the bracket of the base mounting plate as needed.

[0061] exist Figure 2a , Figure 2bIn the arrangement, the first and second connectors are positioned longitudinally spaced apart, generally close to two opposite side ends 232 and 233 of the support plate 205. Connector 206 includes a connector body 240, which is generally cylindrical or has a generally circular cross-section. Connector body 240 includes a wall portion 241 and a base portion 242. Connector body 240 is defined by wall 241. The central axis 249 of each connector 206 is arranged in the direction (X-direction) of the longitudinal axis of the support plate. Connector 206 is connected to support plate 205 by means of bracket 237. Bracket 237 is arranged to extend outward from a first vehicle-facing surface 230 of support plate 205 (shown in an exemplary use orientation in the XY plane) and in a direction transverse to the first vehicle-facing surface 230 (the -Z direction in the figure). Connector 206 is connected to the bracket at its base 242 and extends in a direction substantially parallel to the support plate.

[0062] The device support plate 205 may be made of plastic material. However, it is understood that any suitable material may be used. The device support plate and the connector are preferably formed of the same material to allow for manufacturing using a common manufacturing arrangement. The connector 206 of the device support plate 205 is configured to be flexible and resilient. These characteristics can be achieved by selecting the material of the connector, but also by its form and configuration, which will be further described below.

[0063] The connector wall 241 is configured, by its form and additionally or alternatively by the choice of its material, to have some elasticity and support flexure. The connector 206 is further configured to engage with the fastening element 260. Each connector includes a receiver 256 defined by an internally formed channel extending from the opening 271 through the connector body 240 to the base 242, and configured to receive the fastening element 260.

[0064] refer to Figure 2a , Figure 2b Figures 3a and 3b describe in more detail the mating features of the bracket 202 and the corresponding features of the connector 206. The outer peripheral surface 250 of the connector wall 241 includes a bracket connector member 251 for engagement at the corresponding bracket 202. The bracket connector member 251 includes a circumferential channel 252. The channel 252 is recessed from the outer peripheral surface 250 of the connector 206. The channel 252 has a generally U-shaped channel form. The features of the channel 252, including its depth and width, are selected to correspond to the mating portion of the bracket.

[0065] Referring to Figure 3a, the arm 220 of the bracket 202 includes locking elements 225 located on both sides of the opening 221. The arm 220 further includes a guide 226 that tapers outward relative to the opening 221 and the receiver 222, defining a second locator opening 226'. The locator opening 226' is located outside the receiver opening 221 and is wider. The guide 226 together assists in positioning the connector 206 of the support plate 205 into the receiver 222. The inner surface wall 223 of the arm 220 defines a mating surface for mating with the connector 206. The inner surface wall 223 extends circumferentially about the central axis 229 of the bracket receiver 202. The inner circumferential surface 223 of the arm 220 defines the receiver 222, which has a radius r1 and a length T1 in the axial direction 229. Figure 2a ).

[0066] In order to assemble the support plate 205 to the base plate 202, the bracket connector component 251 is positioned near the bracket 202, and the channel 252 is aligned with the arm 220 of the bracket (see...). Figure 2b (See Figure 3a). Connector 206 is snap-fitted or pushed-fitted into bracket 202 at bracket connector member 251 (see Figure 3b). The connector wall 240 is elastic and flexes to snap-fit ​​into the bracket. When connector 206 is in the insertion position in receiver 222 of bracket 202, bracket arm 220 is located in channel 252. When connected, inner circumferential surface 223 of bracket 202 is located in channel 252 and contacts the base of channel.

[0067] As shown in the exemplary arrangements of Figures 3a and 3b, the connector wall 241 includes end wall members 253 circumferentially spaced around the opening 271. The end wall members 253 are located near / proximal to the bracket connector members 251 and the channel 252, and are separated by slots 243.

[0068] When the support plate 205 and the mounting plate 201 are connected, the axis 229 of the receiver 222 passing through the bracket 202 and the axis 249 of the connector 206 and the fastening element 260 are aligned. During alignment and connection, the fastening element 260, receiver 256, bracket connector member 251 and channel 252, and bracket 202 are all concentrically arranged about the central longitudinal axis (229, 249) of the connection. This concentric arrangement defines the connection between the plates. Each connection is essentially a double-layered or bidirectional connection.

[0069] As mentioned above, in Figure 2a , Figure 2bIn the exemplary arrangement, two plates are connected about a common longitudinal axis by means of two brackets, connectors, and fastening elements. This arrangement provides additional advantages to the mounting system 200. Specifically, due to the connection arrangement of the mounting system about a common axis, the angle or tilt of one plate relative to the other plate can be changed by rotating or moving about the connection. The connection is tightly engaged when fastened; however, some tilting can be provided with the application of force. Tilting or rotation about the common axis can also be provided at the connection between the bracket and the connector before the fastening elements engage in the connector. This arrangement facilitates the accurate positioning of electronic devices or modules on a vehicle. When one plate is already fixed to the vehicle and the other plate is connected to the first plate, the tilt position of one plate relative to the second plate on the vehicle can be further adjusted from its original position.

[0070] exist Figure 2a , Figure 2b In this exemplary arrangement, the central longitudinal axis of the connection is centered between the plates and aligned with the central longitudinal axis of the plates. In this arrangement, there is no surface-to-surface contact between the plates; contact between the plates occurs only at the connection between the connector components and the bracket components. Plates 201 and 205 are spaced apart from each other, and the connection is located between the plates.

[0071] Therefore, in Figure 2a , Figure 2b In this arrangement, the plates are advantageously joined only at the connector and the bracket. The connector, by virtue of its form and configuration, is flexible and has a certain degree of flexibility to facilitate assembly. When these three components (i.e., the fastening element, the connector, and the bracket) are engaged, the connector is effectively held in a rigidly fastened position between two more rigid components on either side of the connector wall.

[0072] In addition, Figure 2b In this exemplary arrangement, when coupled, the surfaces of the two plates are positioned longitudinally offset relative to each other. The ends of the plates are not aligned. The distance of the plate offset is related to the position of the bracket connector of connector 206. Figure 2a , Figure 2b In the arrangement, the two connectors 206 are located on the left side of the connector bracket 237, and the receivers are arranged in the same direction - so that both fastening elements are inserted from the left side.

[0073] It is understandable that the connector and receiver can be arranged in different orientations, for example... Figure 8a , Figure 8b , Figure 8c As shown in the figure, the two receivers are arranged in opposite directions, and fastening elements are inserted from opposite sides of the plate.

[0074] Although the base mounting plate and the device support plate are Figure 2a , Figure 2bThe arrangements and orientations shown are specific examples, but it is understood that they can also be provided in different usage arrangements according to different application requirements. Similarly, although Figure 2a , Figure 2b Each plate in the arrangement has two brackets and two corresponding connectors, but it is understood that the form of these plates may differ from those in the embodiments, and different numbers of brackets or connectors may be provided. Furthermore, the brackets and connectors may be located in different parts of the plate compared to those shown in the exemplary figures.

[0075] While the arrangement of two brackets and connectors aligned about a common axis X allows the board to tilt relative to each other around the joint, the mounting system 200 may include at least one additional bracket and corresponding connector pair not aligned with the common axis at different locations on the board. Although the mounting system connects at aligned joints (e.g.) Figure 2a , Figure 2b (As shown) is configured to provide some relative tilt or rotation about the joint. If the board joint involves connections at misaligned brackets and corresponding connector pairs, then the relative position and angle of the boards will be fixed and static (see...). Figure 9 (Exemplary arrangement).

[0076] In the unsecured position, connector 206 is configured to be flexible and resilient. In particular, this arrangement provides flexibility in the wall 241 so that connector 206 can be inserted into bracket 202, and further allows flexibility at the wall 241 so that fastening element 260 can be inserted into receiver 256.

[0077] In the fastened position, all three parts of the mounting system connection engage and tighten. When engaged, the connector wall 241 is effectively positioned between the fastening element and the bracket (i.e., between two relatively rigid parts), and therefore no longer flexes in a manner that would allow it to in the unfastened position. Instead, when all three parts (bracket, connector, and fastening element) are engaged, the mating between these components is tightened. Thus, these components interlock, and the mating surfaces and opposing surfaces are effectively clamped or tightly engaged.

[0078] The fastening elements, connectors, and receivers are all formed for mating and include corresponding features. The form, features, and dimensions of each component are provided to ensure a secure fastening of the fastening element in the fastening position of the receiver. Furthermore, the shape, features, and dimensions of each component are provided to control the application of interlocking forces on the bracket-connector members of the coupled carriage and connector. Moreover, the layers of each component at the joint (i.e., the innermost fastening element, which is surrounded by the connector, and the connector is surrounded by the carriage) are concentric and circumferentially engaged. Therefore, the joint is about a common axis, and the circumferentially engaged components advantageously allow some rotational movement about the common axis.

[0079] The mounting system 200 is secured to the vehicle and provides robust support for electronic devices or modules based on the three-way interaction of each of the first base mounting plate, the second device support plate, and the third fastening element. Each of these components is configured to interact directly or indirectly with the other two components. These components are formed for interaction and mating, and are further configured to provide controlled forces between the components. The fastening element 260 is configured to interact directly with the connector and indirectly with the base mounting plate 201 via the connector. Different portions of the connector 206 interact directly with the fastening element 260 and the base support plate 201. The fastening element 260 interacts with the support plate 205 in a direction orthogonal to the interaction directions of the mounting plate 201 and the support plate 205. As described above, both bidirectional connections are concentrically arranged.

[0080] refer to Figure 4a , Figure 4b , Figure 4c and Figure 4d Further details of the features of the exemplary connector 206 according to this specification are described, including a receiver 256 formed within the connector body and a corresponding fastening element 260 receivable in the receiver 256.

[0081] As mentioned above, and in Figure 4a and Figure 4b As shown in the 3D diagram, Figure 4a , Figure 4b The components shown, including fastening element 260, connector 206, and bracket 202, have a generally circular cross-section in the transverse or radial direction. (Reference) Figure 4a The fastening element 260 is shown aligned with the connector 206, which engages with the bracket 202.

[0082] Each component is arranged about a common central axis 249 (in the X direction) when aligned or in a fastened position. The interactions of these components include the interactions between the fastening elements and connectors, and between the outer circumferential surfaces of the receiver and the bracket.

[0083] The fastening element 260 includes an elongated body 261 extending from a proximal head 268 to a distal tip 269. The fastening element includes a plurality of engaging members 264, 265-1, 265-2 arranged axially about a central longitudinal axis 249. The outer peripheral wall of each engaging member defines a mating surface for engaging a corresponding portion of the inner peripheral surface 255 of the receiver 256.

[0084] The radial dimension of the engaging member of the fastening element matches the radial dimension of the receiver. The fastening element 260 functions as an expander or expansion member when positioned within the receiver. The overall form of the fastening element in this specification is consistent with... Figure 1 The sales are different, and in contrast, Figure 1 The previous layout is shown. Figure 1 The pin is a relatively narrow pin with a cylindrical body and a constant radius of its transverse cross-section from beginning to end. In contrast, the fastening element 260 has several engagement features arranged axially and formed to provide interaction with the connector and receiver and expansion at the connector and receiver. The diameter or radial range of the fastening element is not constant; the different engagement features each have a specific form and radial range. The fastening element of this specification includes at least two engagement members having peripheral surfaces for engaging corresponding opposing surfaces of the receiver.

[0085] refer to Figures 4a to 4d The first engaging member 264 is configured to interlock with the retainer 275 of the receiver 256. The first engaging member 264 is defined by a portion of the body 267 of the fastening element. The body 267 has a generally oval shape and extends between a neck 263 near the oval base end and a distal end 269 at the tip. Figures 4a to 4d The first engaging member 264 in the arrangement is defined by a curved shoulder 264 that extends outward between the neck 263 of the oval body 267 and the widest portion 262 near its short axis. The outer peripheral surface 264' of the curved shoulder 264 is configured to contact and engage with the retainer 275 of the receiver 256 in use.

[0086] Although the main body of the fastening element 260 is generally oval in shape, it is understood that other suitable shapes can be used, for example, it can be provided in a generally egg-shaped, elliptical or spherical shape.

[0087] The plurality of engaging members further include annular contact members 265-1 and 265-2, which are separated by recessed channels 266. The outer peripheral walls 265-1' and 265-2' of the contact members 265-1 and 265-2 define mating surfaces configured to engage with corresponding portions at the guide 272 of the inner peripheral surface 255 of the receiver 256 when in the fastened position. These contact members have a generally tapered or tapered cylindrical or truncated cone form. The outer peripheral walls 265-1', 265-2' are tapered inwardly in a direction from the proximal end to the distal end of the fastening element, reflecting the form of the receiver. The annular contact members 265-1, 265-2 are located between the head 268 and the body 267 and are configured to engage with the guide 272 of the inner peripheral surface 255 of the receiver 256. The radial range of the proximal head 268 is greater than that of the body 267 and the contact members 265-1, 265-2. A radial step 268' is provided between the head and the first contact member 265-1. In use, in the arrangement shown in the figure, the head 268 remains outside the receiver 256 when the fastening element is engaged.

[0088] The fastening element 260 and the receiver 256 are configured to provide controlled force application between them based on their interaction at a plurality of engaging members. When the fastening element 260 is inserted into the receiver 256, the force generated by the interaction includes radial and axial forces.

[0089] refer to Figures 4a to 4d The exemplary receiver 256 and connector 206 arranged according to this specification are described in further detail. The receiver 256 is defined by a channel extending through the interior of the connector 206. Figure 4a and Figure 4b An external side view is provided. Figure 4c and Figure 4d Transverse and longitudinal (radial and axial) sectional views of the components are provided.

[0090] according to Figures 4a to 4d The connector 206 includes a connector body 240 having a generally cylindrical form defined by connector walls 241. Other suitable forms may also be used, such as tapered or tapered cylindrical forms or truncated cone forms. The connector walls 241 extend from a proximal end 270 to a distal end 279. The walls 241 include an outer peripheral surface 250 and an inner peripheral surface 255. Figure 4a and Figure 4b In the arrangement, the body 240 and the outer peripheral wall 250 are tapered outward at the distal end 279 relative to the proximal end 270. The outer peripheral surface 250 includes a connector mating member 251 defined by a recessed circumferential channel 252 formed relative to the outer peripheral surface 250.

[0091] exist Figures 4a to 4d (and Figures 2a to 2b In the arrangement shown, wall 241 is composed of two or more wall portions 241-1, 241-2 to 241-n. These wall portions are circumferentially spaced around the central axis of connector 206. These wall portions extend in the longitudinal (axial) direction. The wall portions are spaced apart by one or more slots 243. In the arrangement shown, the multiple slots 243-1, 243-2, 243-n are arranged circumferentially spaced. The channel 252 of the outer peripheral surface 250 is composed of channel portions 252-1, 252-2, 252-n, each wall portion including a portion of the circumferential channel. Wall portion 241 further includes an end wall member 253 located near the connector proximal to the opening 271. The outer peripheral wall 250 is tapered inward at the end wall member 253 in the direction of opening 271.

[0092] The inner peripheral surface 255 of wall 241 defines the mating surface of receiver 256. Wall 241 is configured to flex and displace under the action of a force applied between fastening element 260 and inner peripheral surface 255. This includes the force applied by the fastening element at guide 272 and retainer 275. Flexibility is supported by the form of connector wall 240 (including by providing slot 243 and wall portions 241-1, 241-2 to 241-n). Flexibility can also be supported by selecting the material of the connector. Receiver 256 and fastening element 260 are formed with corresponding features and relevant dimensions to provide mating of the fastening element in the receiver.

[0093] The receiver 256 and the inner circumferential surface 255 of the wall include features that influence interlocking. (Reference) Figure 4c and Figure 4d It should be noted that the inner peripheral wall 255 of receiver 256 includes several portions or regions arranged in different axial directions. Receiver 256 extends between the proximal end where the opening 271 for receiving fastener 260 is located and the distal end where the base 242 connecting connector 206 and support plate 205 is located.

[0094] refer to Figure 4c The receiver 256 includes, from proximal to distal end in the axial direction: an opening 271; a guide portion 272; a retainer portion 275; a body portion 277; and a base portion 242.

[0095] Starting from the proximal end 270 of the connector, an opening 271 defines the widest portion of the receiver. From the opening 271, an inner circumferential surface 255 tapers inward to form a tapered guide 272 that extends to the retainer 275. The body portion 277 of the receiver extends distally from the retainer portion 275 to a base 242. The guide 272 further includes: a first proximal region 272-1 configured to engage with a first contact member 265-1 of the fastening element; and a second intermediate region 272-2 configured to engage with the first contact member 265-1 of the fastening element.

[0096] As in Figure 4c and Figure 4d As shown in the exemplary arrangement, the retainer 275 includes a ridge 273 and a recess 274, the ridge 273 defining the narrowest axial portion of the receiver 256. The ridge 273 and the recess 274 together define the retainer 275. The ridge 273 includes a circumferential ridge that extends relative to the inner circumferential surface 255 into the interior space of the receiver. The recess 274 provides a widened portion of the retainer adjacent to the ridge. The ridge 273 is located at the junction of the inner circumferential wall between the narrow end of the tapered guide 272 and the recess 274. The inner circumferential wall is tapered outward at the recess. The orientation and inclination angle of the tapered portion of the inner circumferential wall vary between the retainer and the recess. The inner circumferential wall 274' of the recess 274 is tapered outward relative to the ridge 273 and the central axis. The wall 274' has a curved form conforming to the curved shoulder 263 of the fastening element 260. The ridge 273 and the recess wall 274' define a mating surface that, in use, engages with the mating surface 264' of the fastening element when the fastening element is in the fastened position. The opposing mating surfaces are effectively clamped during engagement.

[0097] Considering the configuration of the receiver and the fastening element, it is understood that when the fastening element is inserted into the receiver, the body 267 of the fastening element will interact with the receiver 256, causing the wall 241 to flex, thereby allowing the body 267 to be positioned in the retainer 275. Positioning of the body 267 at the distal end of the ridge 273 requires displacement of the wall portion 241 to allow the widest portion 262 of the body 267 to advance to the distal end of the retainer 275.

[0098] When the receiver 256 is in a stationary position (without the fastening element positioned therein), the radius of the receiver 256 at the ridge 273 is smaller than the radius at the opening or the radius at the receiver body portion 277 or the base portion 242.

[0099] Although Figures 4a to 4fThe exemplary arrangement of the retainer 275 is defined by a ridge 273 and a recess 274, but it will be understood that the receiver may include one or more suitable alternative forms of retainers. The retainer is configured to conform to the engaging member of the fastening element and provides engagement in a fastened position. A portion of the outer peripheral surface of the fastening element defines a mating surface for engaging with a corresponding mating surface defined by a portion of the inner peripheral surface of the receiver. The opposing mating surfaces engage and effectively interlock or clamp, retaining the fastening element within the receiver.

[0100] When the fastening element 260 is in the fastened position, certain portions of the outer peripheral wall of the fastening element 260 mate with corresponding portions of the receiver due to its configuration.

[0101] As described above and referenced Figure 4d The main body portion 267 of the fastening element 260 is held in a fastened position at the engaging member 264 and the retainer 275. Furthermore, the outer peripheral surfaces of the contact members 265-1 and 265-2 abut and contact the receiver at correspondingly spaced positions 272-1 and 272-2 of the guide portion 272. Therefore, the fastening element 260 is circumferentially engaged with the receiver 256 at multiple locations (including at the retainer 275, the guide portion 272, and the opening 271).

[0102] The forces generated by the interaction between contact members 265-1 and 265-2 and the receiver also play a role in the connection and fixation of the fastening elements and receiver, as well as the connector and bracket. (Reference) Figure 4d and Figure 4f A selected exemplary force generated by the interaction of the receiver and the fastening element is described. The receiver and the fastening element are configured to provide a controlled force between them.

[0103] These forces include forces F3 and F4 in opposing axial directions, which act to hold the fastening element in the receiver. These forces further include forces oriented generally radially or outward relative to the central axis, which cause the receiver 256 and connector wall 241 to flex, thereby tightening the connection of the bracket arm 220 within the channel 252 of the bracket connector member 251. Figure 4d As shown, these forces include, for example, generally radially oriented forces F1 and F2. Tightening occurs between the corresponding three surfaces of all the inner walls of the U-shaped channel and the wall 220 of the bracket. The corresponding surfaces of the bracket arm 220 include the inner circumferential surface 223 and the outer wall adjacent to the receiver. Although in Figure 4d The image is shown in cross-section, but it is understandable that these forces act circumferentially between concentrically connected components.

[0104] Forces F3 and F3' arise from the interaction between the contact members 265-1 and 265-2 of the fastening element and the receiver at the corresponding region of the guide 272. Force F4 arises from the interaction between the engaging member 264 of the fastening element and the receiver at the retainer 275. These interactions are located at axially spaced positions. Forces F3 (F3') and F4 are generally oriented in opposite axial directions.

[0105] refer to Figure 4c , Figure 4d , Figure 4e and Figure 4f The forces generated by the interaction between the fastening element and the receiver, and their effects at the connection between the bracket 220 and the channel 252, are further described. Forces F1 (and F1') arise from the interaction between the contact member 265-1 of the fastening element and the receiver at the guide 272. (See reference...) Figure 4f The diagram illustrates the interaction between the mating surface 265-1 and the region 272-1 of the guide portion (where these corresponding surfaces come into contact). Force F3 is similarly generated by the interaction between the contact member 265-1 and the guide portion of the receiver. These interactions occur at the mating region 272-1 of the guide portion between the outer peripheral portion 265-1' of the fastening element and the inner peripheral surface 255.

[0106] Forces also arise from the interaction between the second contact member 265-2 and the receiver. In particular, as shown, the outer peripheral surface 265-2' contacts the region 272-2 of the receiver, and the forces include forces F3' and F1'.

[0107] Force F2 arises from the interaction between the engaging member 264 of the fastening element and the receiver at the retainer 275. Force F4 similarly arises from the interaction between the engaging member 264 and the retainer of the receiver. These interactions are the interaction between the outer peripheral portion 264' of the engaging member and the inner peripheral surface 255 at the retainer 275.

[0108] The interactions between contact members 265-1, 265-2 and the receiver are axially spaced relative to the interactions between engagement member 264 and the receiver. Forces (e.g., exemplary forces F1 and F2) are generally outwardly oriented, including generally radially outward directions and directions orthogonal to or angular to the central axis. The interaction between the fastening element and the receiver is circumferential, and forces F1 and F2 act circumferentially. These exemplary forces F1 and F2 are embodiments of forces relating to the deflection of the receiver, and they provide for the expansion of the receiver.

[0109] Figures 4a to 4fThe exemplary arrangement of the fastening element is not configured to provide continuous contact between its outer peripheral wall and the inner peripheral wall of the receiver. Instead, the contact member 265-1 or 265-2 and the engaging member 264 are recessed and configured to contact the receiver at corresponding locations, said corresponding locations including the proximal region 272-1 of the guide 272, the intermediate region 272-2 of the guide, and the retainer 275. Providing spaced-apart contact members and engaging members (separated by recesses) provides control over the direction of force between the fastening element and the receiver, as well as control over the direction of deflection.

[0110] like Figure 4d and Figure 4f As shown, the bracket connector component 251 and the channel 252 are located on the outer peripheral surface 250 of the connector at a position between the retainer 275 and the contact member 265-1 contact guide area 272-1.

[0111] Therefore, the forces caused by the insertion of the fastening element between the connector wall 241 and the bracket 202 include outward-pointing forces (including forces F1, F1', and F2), which are applied to the connector wall 241 at both the distal and proximal ends of the channel 252. This provides flexural force to the connector wall, including forces, for example, in directions F5 and F6, which provides tightening of the connection between the bracket 220 and the channel 252 and secures the bracket within the channel. As shown, these forces include torque in direction F5 and the force generated by the torque in direction F6.

[0112] Looking further into the overall interactions and, for example, the bending forces F5 and F6, it can be noted that the outer peripheral wall 265-1' also contributes to providing expansion by applying a force at 272-1, which provides bending in the proximal direction (including F5) of the connector wall 241, where mating occurs between surface 265-1' and the receiver surface 272-1. The additional force F6 is generated by torque.

[0113] These interactions are supported by the tapered shape of the outer peripheral wall 265-1' of the contact member 265-1 and the tapered shape of the guide portion 272 of the receiver 256 (including at the contact area 272-1). These interactions are further supported by the tapered shape of the outer peripheral wall 265-2' of the contact member 265-2 and the tapered shape of the guide portion 272 of the receiver 256 (including at the contact area 272-2').

[0114] Channel 252 defines a recess in the outer peripheral surface 250 of connector wall 241. As described above, this channel is a circumferential channel. Under the action of forces applied at the distal and proximal ends of the channel by retainer 275 and upper guide 272-1, the connector wall flexes in the direction of the channel. These forces include forces in the direction indicated as F5 (torque) and F6 (force generated by torque). Connector 206 and channel are flexible and elastic, and tighten around the more rigid arm 220 of bracket 202.

[0115] refer to Figure 4e This illustrates the connection between the bracket 220 and the channel 252 before the fastening element is inserted. As described, the connection is achieved through a snap-fit ​​engagement, and as shown, there may be some gaps G (gap G1 and gap G2) between the wall of the channel 252 and the corresponding portion of the receiver arm 220. Reference Figure 4f Regions 272-1, 272-2, and 275 of the receiver interact with the contact and engagement members of the fastening element. Furthermore, it is shown that displacement or deflection of the receiver wall causes the connection of the bracket arm 220 in the channel to tighten. Figure 4e The gap shown is now closed, and the base and sidewalls of the U-shaped channel 252 are clamped tightly against the inner circumferential surface 223 and sidewalls of the bracket. The overlap between the sidewalls of the channel 252 and the arms 220 of the bracket... Figure 4e and Figure 4f The overlap of OL1 is shown in the diagram. The overlap of OL1 depends on the depth of channel 252. The gap indicated between the inner surface of channel 252 and the corresponding portion of the bracket arm closes as the connection tightens. This tightening is also supported by the channel, which is formed of a relatively flexible / flexible plastic material, allowing it to move to engage tightly with the corresponding wall of the more rigid bracket.

[0116] F5 is the torque generated by F1. F6 is the force generated by torque F5. Forces F1' and F3' are weaker than F1 and F3. The area of ​​interaction between the pin (also called the fastening element) and the flexible snap-fit ​​feature (also called the connector) is also shown in the figure with dashed lines.

[0117] The fastening element 260 applies a force to the inner peripheral wall of the connector. Under the applied force, the connector wall 241 displaces and contacts the bracket. The connector wall 241 is configured to be resilient to allow for snap-fit ​​engagement with the bracket and to allow for insertion of the fastening element. When both the fastening element 260 and the bracket 202 engage with the connector 206, each of these more rigid components (fastening element and bracket) exerts a reaction force on the clamping portion of the connector 205, thus constraining and maintaining it in a fixed state. When the fastening element and the bracket interlock, the connector 205 does not flex as it would in its resting position.

[0118] The receiver 256 is configured to receive its oval-shaped, elongated body portion 267 after the fastening element 260 is pushed into its fastening position within the receiver. The shape and size of the receiver 256 are designed to conform to the shape and size of the fastening element 260, thereby generating biasing forces F3 and F3' against the fastening element in the direction in which the fastening element is pushed into place. In this way, the biasing force F4 provided by the interaction between the retainer 275 and the shoulder 264 of the fastening element 260 causes the retainer to securely hold and maintain the fastening element 260 in place, while the fastening element 260 simultaneously generates a biasing force F2 against the elongated wall portion 241 to secure them within the bracket 202 at the channel 252. The forces, including forces F1, F1', F2, F3, F3', and F4, and the interaction of the three components (first base mounting plate, second support plate, and fastening element), together provide a secure connection between the support plate and the base mounting plate. Torque and the forces generated by torque have been discussed above, and these forces play a role, particularly in fixing and tightening the connection between the bracket and the connector.

[0119] When the fastening element 260 is inserted into the receiver 256, the fastening element 260 applies a force to the connector wall 240, causing the connector wall 241 to move from a first static position where there is no interaction between the fastener and the receiver to a second fastened position, at which point the fastening element 260 is located in the receiver 256.

[0120] Referring to Figures 5a, 5b, 5c, and 5d, other exemplary fastening elements are described. These fastening elements share common features with fastening element 260 and are referred to by the same reference numerals where appropriate.

[0121] As described above, the various arrangements of fastening elements are integral components of the mounting system 200 of this specification. The form of the fastening elements, including their shape and size, corresponds to the form of the corresponding receivers 256. The fastening elements are configured as expansion elements. Each fastening element and its corresponding receiver includes a corresponding mating feature. The fastening elements and their corresponding receivers are configured to provide a controlled force between them and are used to connect the base mounting plate and the device support plate. It is understood that the above references may be provided. Figures 2a to 4f The description includes suitable alternative forms of fastening elements and corresponding receivers.

[0122] Figure 5b provides a myopic stereoscopic view of fastening element 260.

[0123] Referring to Figure 5a, a fastening element 1260 is depicted. The fastening element 1260 includes an elongated body 261 extending from a head 268 at a proximal end to a tip 269 at a distal end. The fastening element includes an engaging member 264 and a contact member 265, which are axially arranged about a central longitudinal axis 249. The outer peripheral walls of the engaging member and the contact member define mating surfaces that engage with corresponding portions of the inner peripheral surface 255 of the receiver 256.

[0124] The first engaging member 264 is configured to interlock with the retainer of the corresponding receiver to engage the fastening element with the receiver. The first engaging member 264 includes a generally oval-shaped body 267 extending between a neck 263 near the oval base end and a distal end 269 at the tip. A curved shoulder 264' of the outer peripheral surface of the body 267 extends outward relative to the axis between the neck 263 and the widest portion 262 of the oval body 267. The outer peripheral surface at the curved shoulder 264' defines a mating surface configured to contact and engage with the retainer 275 of the receiver 256 in use.

[0125] The fastening element 1260 further includes an annular contact member 265, which is separated from the body 267 by a recessed channel at the neck 263. An outer peripheral wall 265' defines a mating surface configured to engage a corresponding portion of the inner peripheral surface 255 of the receiver 256 when in the fastened position. The outer peripheral wall 265' also functions in providing expansion. This provides a bend at the proximal end of the connector wall 241, at which mating exists between the receiver surface 265' and surface 272'. The outer peripheral wall 265' is tapered inwardly (radially) in the direction from the proximal to the distal end of the fastening element, reflecting the shape of the receiver. A radial step 268' is provided between the head 268 and the first contact member 265. In use, in the arrangement shown in the figures, the head 268 remains outside the receiver 256 when the fastening elements are engaged. The selection of the size and features of the fastening element takes into account the form, size and features of the corresponding receiver 256 of connector 206.

[0126] The fastening element 1260 and the receiver 256 are configured to provide controlled force application when they interact with each other. When the fastening element 1260 is inserted into the receiver 256, the forces generated by the interaction include: a force in a generally radially outward direction; a force in a direction orthogonal to the central axis of the receiver and the fastening element and the bracket of the base mounting plate; and a force in the axial direction.

[0127] Figure 5c and Figure 6The fastening element 2260 is similar to the fastening element in FIG. 5a. However, an additional contact member 2265 is provided between the first contact member 265 and the head 268. A step 268' is provided between the peripheral surface of the head 268 and the contact member 2265. The contact member 2265 includes a plurality of locking members 2266. The contact member 2265 is annular in shape with a depth of d5, and the locking members 2266 extend radially outward from the contact member 2265 between the outer peripheral wall of the contact member 2265 and the outer peripheral wall of the head 268. The locking members 2266 are spaced apart. The locking members 2266 are arranged relative to the contact member 2265 in a spoke-like manner and have a depth of d5. The locking members 2266 are configured to engage with the end members 253 of the corresponding connector (FIG. 3a, FIG. 5 ... Figure 4a Interlocked with Figures 7a to 7b). When the fastening element 2260 and the connector are engaged, the locking member 2266 is located in the slot 243 of the connector wall 241 between the end members 253.

[0128] Referring to FIG. 5d, another fastening element 3260 is depicted according to an exemplary arrangement of this specification. The overall form and configuration of this fastening element are similar to those of the fastening elements in FIGS. 5a to 5c. The fastening element 3260 further includes a body portion 3267 that is generally spherical in shape. The body portion 3267 includes a recess 3264 that defines an engaging member. The recess 3264 includes a V-groove formed to be recessed into the body portion 3267 near its circumference. The V-groove extends circumferentially around the body portion 3267. The recess 3264 includes: an inner base portion 3265; and a wall 3264' that tapers outwardly from the base portion 3265 to an outer end 3263 to define the V-shape.

[0129] The fastening element 3260 further includes an annular contact member 265, which is separated from the body 3267 by a recessed channel at the neck 263. An outer peripheral wall 265' defines a mating surface configured to engage a corresponding portion of the inner peripheral surface 255 of the receiver 256 when in the fastened position. The outer peripheral wall 265' is tapered inwardly (radially) from the proximal end 269 of the fastening element 3260, reflecting the shape of the receiver. A radial step 268' is provided between the head 268 and the first contact member 265. In use, in the arrangement shown in the figures, the head 268 remains outside the receiver 256 when the fastening elements are engaged. The selection of the size and features of the fastening element takes into account the shape, size, and features of the corresponding receiver 256 of the connector 206.

[0130] The force generated by the interaction between the fastening element 3260 and the receiver 256 is shown. (See above reference.) Figures 4a to 4fThe forces include: forces F3 and F4 in the axial direction; forces F1 and F2' in the generally outward or radial direction; torque F5; and the force generated by torque F6.

[0131] Referring to Figures 7a and 7b, the fastening element 3260 of Figure 5d is shown located in the corresponding receiver 256 of the connector. This receiver is configured to include a retainer 3275 conforming to the form of the recess 3264.

[0132] refer to Figure 8a The alternative installation system 1200 is described. This installation system 1200 is similar to... Figures 2a to 2b The mounting system, where the same reference numerals are used in appropriate places, includes a base mounting plate 1201 and a device support plate 1205. The base mounting plate 1201 includes a bracket 1202 for engagement with a connector 1206 of the device support plate 1205. The connector 1206 of the device support plate 1205 has a degree of flexibility and elasticity. The base mounting plate 1201 and bracket 1202 are relatively more rigid than the connector 1206 of the device support plate 1205. The device support plate and connector may be made of plastic. The base mounting plate may be made of metal. However, it is understood that any suitable material with the desired rigidity or flexibility may be used.

[0133] When connecting, such as Figure 8b As shown, plates 1201 and 1205 are longitudinally offset and spaced apart in the transverse direction. Plates 1201 and 1205 contact each other at connector 1206 and bracket 1202. A coupling is located between these plates. When these plates are coupled, the central longitudinal axis 1229 through bracket 1202 and the central longitudinal axis 1249 through connector 1206 are aligned. A fastening element 1260 (as shown with reference to FIG. 5b) is provided to secure the plates together in the coupled position. When engaged, the fastening element, connector, and bracket are all concentrically arranged about the central longitudinal axis of the coupling. The connection between the fastening element and the receiver of the connector is in the axial or longitudinal direction. The connection between the connector and the bracket is in a direction orthogonal to the axial direction.

[0134] exist Figure 8b In the arrangement, with Figures 2a to 2b Compared to the mounting system, the fastening element 1260 is inserted into the receiver of connector 1206 in the opposite direction. The first and second connectors 1206 are axially aligned but in opposite directions. This arrangement is advantageous in applications where connector entry points are limited or space is scarce, as the fastening element can be inserted into the corresponding receiver from an external location on the plate and in the connection.

[0135] refer to Figures 2a to 2b The description of the installation system 200 is applicable to Figures 8a to 8c The installation system is 1200.

[0136] refer to Figure 8c This illustrates some exemplary forces provided by the interaction between the fastening element 1260 and the connector 1206. This arrangement and the resulting forces are consistent with reference to... Figure 4d The description is similar. Exemplary forces include generally outwardly oriented forces that act to flex the connector wall 241. These forces include outward or radially oriented forces F1 and F2', as shown, which act near and at the proximal ends of the carriage connector member 251 and the channel 252. These radially and outwardly oriented forces are circumferentially oriented at the connector wall 241 and provide outward displacement or flexing of the connector wall relative to the central longitudinal axis, which provides tightening of the carriage connection in the channel 252. (See previous reference...) Figure 4f The tightening described is also suitable for Figure 8c The arrangement.

[0137] The tightening of the connection is performed between all three surfaces of channel 252 and the corresponding three mating surfaces of the bracket (i.e., the inner circumferential surface 223 and the sidewall of the arm adjacent to the inner circumferential surface). As shown, channel 252 has a U-shaped form. Figure 8c The enlarged view of the bracket provided shows that the force includes force F5, which acts to cause the connector wall to bend in the direction of channel 252. The connector is flexible and elastic, and flexes at the channel to tightly engage with the bracket located within the channel. All three walls of the channel are pressed against the corresponding portions of the bracket. Force F5 is torque. An additional force F6 is provided to effectively clamp the channel and the bracket. Force F6 is generated by torque.

[0138] The tightening force driving the connection at the channel and bracket includes those forces generated by the interaction between the fastening element and the receiver at the mating surface 265' of the first contact member 265 and the corresponding portion 272-1 of the guide 272. The force between the engaging member 264 and the retainer 275 also plays a role. This interaction includes the interaction between the outer peripheral surface 264' and the inner peripheral surface 274' of the engaging member at the retainer.

[0139] Exemplary forces also include forces (F3 and F4) in opposite axial directions, which work together to hold the fastening element in the receiver. The tapered outer peripheral wall 265' defining the contact surface of the contact member 265, when pushed into place and engaged with the receiver 256, generates a biasing force F3 in the opposite direction to the direction of insertion into the channel. This biasing force F3 generated by the contact member 265 on the receiver is opposed to the biasing force F4 generated by the interaction between the fastening element and the retainer 275 at the shoulder 264. These biasing forces F3 and F4 work together simultaneously to securely hold the fastening element 1260 in place within the receiver 256. The wall 241 of the connector 1206 is effectively clamped between the relatively rigid fastening element 1260 and the bracket 1202.

[0140] For reference Figures 2a to 2b As described in the arrangement, plates 1201 and 1205 are connected about common axes 1229 and 1249 (the X direction in the figure). The connection is circumferential, and the arrangement allows these plates to rotate relative to each other about the connection. Therefore, when the mounting system is installed and secured in the vehicle, it is still possible to adjust the tilt of one plate relative to the other about the axis. This allows for adjustments to the electronic devices or modules supported on them.

[0141] refer to Figure 9 This description illustrates another exemplary arrangement of the mounting system 4200 according to this specification. The mounting system 4200 includes a base mounting plate 4201 with brackets 4202. A device support plate 4205 includes connectors 4206 for engagement with corresponding brackets 4202. Three pairs of connectors 4206 and corresponding brackets 4202 are provided. Two pairs of connectors 4206-1, 4206-2 and brackets 4202-1, 4202-2 are arranged such that when the axis 4249 passing through the connector is engaged, it aligns with the axis 4229 passing through the bracket (direction X1 in the figure). A third pair of connectors 4206-3 and brackets 4202-3 is arranged such that this third engagement is not aligned with the first two pairs of connectors and brackets. If plates 4201 and 4205 are connected at the aligned bracket and connector pairs, it is possible to achieve the desired connection as described in the reference. Figures 2a to 2b As described, the tilt of one plate relative to another is changed by rotating or tilting one plate or the other about the axis of the connection. If the plates are connected at misaligned brackets and connectors, then the plates will be connected in a static arrangement, and tilting is not possible.

[0142] This specification provides an improved mounting system according to the various exemplary arrangements shown, for mounting electronic devices or electronic modules into a vehicle. This specification advantageously solves problems associated with previous systems. A flexible connector is configured to snap-fit ​​with a more rigid mounting plate at the bracket. Due to tolerances, there will be some clearance or gap between the rigid and flexible parts. To eliminate this gap and to make the snap-fit ​​joint robust against loads, stresses, and noise or rattling due to tolerances, fastening elements are provided. The fastening elements are configured to be fitted to the first and second plates in a direction perpendicular to or orthogonal to the snap-fit ​​direction.

[0143] This arrangement includes the special interaction features of the first and second plates and the fastening elements, and advantageously provides a safe and robust connection, solving problems associated with existing arrangements. The connection is circumferential and configured to allow rotation about the connection axis to allow for positioning or repositioning of electronic devices. The support plates and fastening elements can be made of plastic materials and can be manufactured using the same system.
