Description

Technical Field

[0001] This disclosure relates to the field of electronic product technology, and in particular to a hinge device and a mounting bracket for vehicle-mounted electronic equipment. Background Technology

[0002] With technological advancements, electronic devices are increasingly being used in vehicles. Electronic products can be mounted on the vehicle's structure using mounting brackets, which typically incorporate swivel connections to allow for different viewing angles. However, in these swivel connections, the assembly gaps between the rotating components can easily lead to abnormal noises under the vibrations and impacts of the vehicle's operating environment, negatively affecting the user experience. Utility Model Content

[0003] To overcome the problems existing in the related technologies, this disclosure provides a hinge device and a mounting bracket for vehicle electronic equipment.

[0004] According to a first aspect of the present disclosure, a hinge device is provided, connected between a bracket body and a bracket base of an electronic device mounting bracket, the hinge device comprising:

[0005] The first connector is used to connect to the bracket body;

[0006] A second connector is used for connection with the bracket base; and

[0007] A rotating connection mechanism is provided between the first connecting member and the second connecting member. The rotating connection mechanism includes a first rotating body and a second rotating body that are rotatably connected relative to each other, wherein:

[0008] The first rotating body is form-locked to the first connecting member;

[0009] The second rotating body is engaged with the second connecting member.

[0010] The technical solutions provided by the embodiments of this disclosure can include the following beneficial effects: The hinge device provided by this disclosure includes: a first connecting member, a second connecting member, and a rotating connecting mechanism. The rotating connecting mechanism is connected between the first connecting member and the second connecting member, enabling the first connecting member and the second connecting member to rotate relative to each other, thereby realizing the adjustment of the angle of the electronic device. The rotating connecting mechanism includes a first rotating body and a second rotating body that are rotatably connected, wherein the first rotating body is form-locked to the first connecting member, and the second rotating body is form-locked to the second connecting member. The form-locked connection between the rotating body and the connecting member helps to eliminate assembly gaps, thereby eliminating abnormal noises caused by assembly gaps in automotive use scenarios and improving the user experience.

[0011] In some possible implementations, the first connector includes a first bushing portion, and the first rotating body and the first bushing portion are riveted together. Using a riveting connection improves the reliability of the connection and is both simple and reliable.

[0012] In some possible implementations, the first rotating body is provided with a plurality of first non-smooth structures along the circumference. This can improve the locking force by increasing the friction of the contact surfaces.

[0013] In some possible implementations, the first non-smooth structure is configured as a toothed structure. This is beneficial for providing a better coefficient of friction and torsional resistance.

[0014] In some possible implementations, the first rotating body is provided with a first limiting structure, and the inner wall of the first bushing is provided with a second limiting structure. The first limiting structure and the second limiting structure cooperate to restrict the rotation of the first connecting member relative to the first rotating body. This approach helps to improve the rotational strength of the first connecting member during rotation and avoids any misalignment during rotation.

[0015] In some possible implementations, the second connector includes a second bushing portion, and the second rotating body and the second bushing portion are riveted together. Using a riveting connection improves the reliability of the connection, and the process is simple and reliable.

[0016] In some possible implementations, the second rotating body is provided with a plurality of second non-smooth structures along the circumference. This allows for an increase in locking force by increasing the friction of the contact surfaces.

[0017] In some possible implementations, the second non-smooth structure is configured as a toothed structure. This is beneficial for providing a better coefficient of friction and torsional resistance.

[0018] In some possible implementations, the second rotating body is provided with a third limiting structure, and the inner wall of the second bushing is provided with a fourth limiting structure. The third and fourth limiting structures cooperate to restrict the rotation of the second connecting member relative to the second rotating body. This approach helps to improve the rotational strength of the second connecting member during rotation and avoids any misalignment during rotation.

[0019] In some possible implementations, the first and second rotating bodies are coaxially arranged and rotatably coupled relative to each other, and a damping mechanism is provided between the first and second rotating bodies to allow them to hover at any position. This enables stepless adjustment of the angle of the electronic device.

[0020] In some possible implementations, the damping used to suspend the first and second rotating bodies is friction damping. Using friction damping to suspend the first and second rotating bodies results in a simple and reliable structure, occupies less space, has lower cost, and requires no external energy source.

[0021] In some possible implementations, the rotary connection mechanism further includes a preload assembly that provides a preload force for generating frictional damping between the first and second rotating bodies. The preload assembly maintains frictional damping between the first and second rotating bodies, preventing wear and tear on the first and second rotating bodies due to prolonged frictional contact from affecting the hovering performance.

[0022] In some possible implementations, the second rotating body includes a connecting portion and a rotating shaft portion. The connecting portion is form-locked to the second connecting member. The first rotating body is rotatably sleeved on the rotating shaft portion. A flange is formed between the connecting portion and the rotating shaft portion. A pre-tightening component is disposed on the side of the first rotating body opposite to the flange, and the pre-tightening component provides a pre-tightening force for the first rotating body to abut against the flange. This approach helps eliminate axial clearance, avoids loosening of the connection due to vibration, ensures the reliability of mechanical transmission, and reduces abnormal noises in vehicle-mounted applications.

[0023] In some possible implementations, the pre-tightening assembly includes a locking nut and a washer assembly. The end of the rotating shaft opposite the connecting portion has a threaded structure, the locking nut engages with the threaded structure, and the washer assembly is disposed between the locking nut and the first rotating body. Tightening the locking nut allows for convenient adjustment of the frictional damping between the first and second rotating bodies, maintaining the frictional damping between them and optimizing the feel of angle adjustment in electronic devices.

[0024] In some possible implementations, multiple rotary connection mechanisms are provided, spaced apart along the rotation axis of the first connector. This is beneficial for improving the connection strength and rotational reliability between the first and second connectors in vehicle-mounted applications.

[0025] According to a second aspect of the present disclosure, a vehicle-mounted electronic device mounting bracket is provided, comprising a bracket body, a bracket base, and a hinge device connecting the bracket body and the bracket base, wherein the bracket body is used to mount an electronic device, the bracket base is used to mount on a vehicle body, and the hinge device is any of the hinge devices described above.

[0026] In some possible implementations, the bracket body is provided with a first mounting hole, the first connector is provided with a second mounting hole, and the vehicle electronic device mounting bracket further includes a connecting shaft, which passes through the first mounting hole and the second mounting hole in sequence and is form-locked with the first mounting hole and the second mounting hole. This eliminates assembly gaps, thereby eliminating abnormal noises caused by assembly gaps in vehicle use scenarios.

Detailed Implementation

[0043] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0044] It should be noted that all actions involving the acquisition of signals, information, or data in this disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the location is situated, and with authorization from the owner of the relevant device.

[0045] like Figures 1 to 12 As shown, this exemplary embodiment provides a hinge device 300 suitable for an electronic device mounting bracket. Further, the rotating connection device 300 is suitable for a vehicle-mounted electronic device mounting bracket. The electronic devices here include, but are not limited to, portable mobile electronic devices such as mobile phones and tablets, or fixed electronic devices such as vehicle-mounted displays.

[0046] Taking a vehicle-mounted electronic device mounting bracket as an example, it includes a bracket body 100 and a bracket base 200. The bracket body 100 is used to mount electronic devices, and the bracket base 200 is used to mount the electronic device mounting bracket to the vehicle body, for example, to the rear of the front seat back. A hinge device 300 is connected between the bracket body 100 and the bracket base 200 to realize relative rotation of the bracket body 100 with respect to the bracket base 200, thereby enabling the angle of the electronic device mounted on the bracket body 100 to be adjustable.

[0047] The hinge device 300 provided in this disclosure includes: a first connecting member 1, a second connecting member 2, and a rotating connection mechanism 3. The first connecting member 1 is used to connect to the support body 100; the second connecting member 2 is used to connect to the support base 200; the rotating connection mechanism 3 is connected between the first connecting member 1 and the second connecting member 2, allowing the first connecting member 1 and the second connecting member 2 to rotate relative to each other. The rotating connection mechanism 3 includes: a first rotating body 31 and a second rotating body 32 that are rotatably connected relative to each other, wherein: the first rotating body 31 is form-locked to the first connecting member 1; and the second rotating body 32 is form-locked to the second connecting member 2.

[0048] It should be noted that form-locking connection refers to a connection method in which two components are locked together through local plastic deformation or geometric fit. Form-locking connections allow the two components to fit tightly together, eliminating assembly gaps between them to reduce noise and improve the reliability of the connection.

[0049] For example, in automotive applications, electronic device mounting brackets need to meet NVH (Noise, Vibration, and Harshness) performance requirements. In related technologies, there is an assembly gap between the rotating connection mechanism 3 and the first connecting member 1 and the second connecting member 2, which can easily cause abnormal noises under vehicle vibration and impact, affecting the user experience. However, the first rotating body 31 and the first connecting member 1, as well as the second rotating body 32 and the second connecting member 2 in this disclosure, adopt a form-locking connection method, which helps to eliminate this assembly gap. That is, there is no assembly gap between the installed rotating body and the connecting member, thereby eliminating abnormal noises caused by assembly gaps in automotive applications and improving the user experience.

[0050] Form-locking connections between the rotating body and the connecting member can be achieved in various ways. In some possible embodiments, the first connecting member 1 includes a first bushing portion 11, and the first rotating body 31 and the first bushing portion 11 are riveted together. Riveting connections improve the reliability of the connection and are simple and reliable in process. In addition, the stress is dispersed by uniformly distributed deformation areas, which helps to avoid local stress concentration. In other embodiments, form-locking connections can also be achieved by heat shrink fitting and stamping locking, etc., which will not be described in detail in this disclosure.

[0051] To further improve the strength of the riveted connection between the first rotating body 31 and the first bushing 11, in some possible embodiments, such as Figure 4 As shown, the first rotating body 31 has a plurality of first non-smooth structures 311 arranged circumferentially. This arrangement of the first non-smooth structures 311 on the first rotating body 31 can improve the locking force by increasing the friction of the contact surface. Optionally, the first non-smooth structures 311 are constructed as toothed structures, which is beneficial for providing a higher coefficient of friction and torsional resistance, and has a lower risk of material deformation and interference. The interference between the first non-smooth structures 311 and the inner wall of the first bushing portion 11 can be configured to be 0.02 mm to 0.1 mm. By setting the interference between the first non-smooth structures 311 and the inner wall of the first bushing portion 11 within a reasonable range, it is beneficial to ensure sufficient riveting strength between the first rotating body 31 and the first bushing portion 11, while also reducing assembly difficulty.

[0052] In some possible implementations, see also Figure 4 , Figure 6 and Figure 7 The first rotating body 31 is provided with a first limiting structure 3121, and the inner wall of the first bushing portion 11 is provided with a second limiting structure 3122. The first limiting structure 3121 and the second limiting structure 3122 cooperate to restrict the rotation of the first connecting member 1 relative to the first rotating body 31. Based on the embodiment in which the first rotating body 31 and the first connecting member 1 are connected by a form-locking connection, the addition of a limiting structure to restrict the rotation of the first connecting member 1 relative to the first rotating body 31 is beneficial to further enhance the rotational strength of the first connecting member 1 when it rotates and avoid the occurrence of play when the first connecting member 1 rotates.

[0053] The first limiting structure 3121 and the second limiting structure 3122 can be implemented in various ways. For example, the first limiting structure 3121 can be constructed as a first limiting surface, and the second limiting structure 3122 can be constructed as a second limiting surface on the inner wall of the first bushing portion 11, with the first limiting surface and the second limiting surface having a zero-clearance fit. Figure 7 The embodiment shown includes two opposing second limiting structures 3122. In other embodiments, a greater number of first limiting structures 3121 and second limiting structures 3122 may be provided. In addition to using limiting surfaces, in some other possible embodiments, a snap-fit ​​method may also be used, for example, a slot extending axially is provided on the inner wall of the first bushing portion 11, and a protrusion is provided on the first rotating body 31 that can be inserted axially into the slot and limited circumferentially.

[0054] In some possible implementations, the second connector 1 includes a second bushing portion 21, a second rotating body 32, and a riveted connection between the second bushing portion 21 and the second rotating body 32. The riveting connection method improves the reliability of the connection and is simple and reliable in process. Furthermore, the uniformly distributed deformation area helps to disperse stress and avoid localized stress concentration.

[0055] To further improve the riveting strength between the second rotating body 32 and the second bushing 21, in some possible embodiments, such as Figure 4 As shown, the second rotating body 32 is provided with a plurality of second non-smooth structures 3211 along the circumference. This method of providing second non-smooth structures 3211 on the second rotating body 32 can improve the locking force by increasing the friction of the contact surface. Optionally, the second non-smooth structures 3211 are constructed as toothed structures, which is beneficial for providing a higher coefficient of friction and torsional resistance, and has a smaller risk of material deformation and interference. The interference between the second non-smooth structures 3211 and the inner wall of the second bushing portion 21 can be configured to be 0.02 mm to 0.1 mm. By setting the interference between the second non-smooth structures 3211 and the inner wall of the second bushing portion 21 within a reasonable range, it is beneficial to ensure sufficient riveting strength between the second rotating body 32 and the second bushing portion 21, while also reducing the difficulty of process installation.

[0056] In some possible implementations, see also Figure 4 , Figure 8 and Figure 9 The second rotating body 32 is provided with a third limiting structure 3241, and the inner wall of the second bushing portion 21 is provided with a fourth limiting structure 3242. The third limiting structure 3241 and the fourth limiting structure 3242 cooperate to restrict the rotation of the second connecting member 2 relative to the second rotating body 32. Based on the embodiment in which the second rotating body 32 and the second connecting member 2 are connected by a form-locking connection, the addition of limiting structures to restrict the rotation of the second connecting member 2 relative to the second rotating body 32 is beneficial to further enhance the rotational strength of the second connecting member 2 during rotation and avoid any misalignment during rotation.

[0057] The third limiting structure 3241 and the fourth limiting structure 3242 can be implemented in various ways. For example, the third limiting structure 3241 can be constructed as a third limiting surface, and the fourth limiting structure 3242 can be constructed as a fourth limiting surface on the inner wall of the second bushing portion 21, with the third limiting surface and the fourth limiting surface having a zero-clearance fit. Figure 9The embodiment shown includes two opposing fourth limiting structures 3242. In other embodiments, a greater number of third limiting structures 3241 and fourth limiting structures 3242 may be provided. In addition to using limiting surfaces, in some other possible embodiments, a snap-fit ​​method may also be used, for example, a slot extending axially is provided on the inner wall of the second bushing portion 21, and a protrusion is provided on the second rotating body 32 that can be inserted axially into the slot and limited circumferentially.

[0058] To achieve a relative rotational connection between the first rotating body 31 and the second rotating body 32. In some embodiments, such as Figure 3 and Figure 4 The first rotating body 31 and the second rotating body 32 are coaxially arranged and can rotate relative to each other, with damping provided between them to allow them to hover at any position. This damping, allowing the first rotating body 31 and the second rotating body 32 to hover at any position, enables stepless adjustment of the electronic device's angle. Furthermore, the form-locking connection between the first rotating body 31 and the first connecting member 1, and between the second rotating body 32 and the second connecting member 2, eliminates rotational play during adjustment. The coaxial arrangement of the first rotating body 31 and the second rotating body 32 also helps reduce space occupancy and product size.

[0059] The damping used to suspend the first rotating body 31 and the second rotating body 32 can be friction damping. Using friction damping to suspend the first rotating body 31 and the second rotating body 32 results in a simple and reliable structure, occupies less space, has lower cost, and requires no external energy. In other possible embodiments, the first rotating body 31 and the second rotating body 32 can also be driven by a motor or electromagnetic drive.

[0060] In some embodiments, frictional damping can be generated by the static friction between the first rotating body 31 and the second rotating body 32, for example, the first rotating body 31 is fitted onto the outside of the second rotating body 32 with an interference fit. In other embodiments, the rotary connection mechanism 3 may further include a preload assembly 33, which provides a preload force for generating frictional damping between the first rotating body 31 and the second rotating body 32. The preload assembly 33 can maintain the frictional damping between the first rotating body 31 and the second rotating body 32, preventing the first rotating body 31 and the second rotating body 32 from wearing down due to prolonged frictional contact, thus affecting the hovering effect.

[0061] As one possible implementation method, the preload assembly 33 is used to generate and maintain frictional damping, such as Figure 3As shown, the second rotating body 32 includes a connecting portion 321 and a rotating shaft portion 322. The connecting portion 321 is connected to the second connecting member 2 via a form-locking connection. The first rotating body 31 is rotatably sleeved on the rotating shaft portion 322. A flange 323 is formed between the connecting portion 321 and the rotating shaft portion 322. A pre-tightening assembly 33 is disposed on the side of the first rotating body 31 opposite to the flange 323, and the pre-tightening assembly 33 provides a pre-tightening force for the first rotating body 31 to abut against the flange 323. This method helps to eliminate axial clearance, avoid loosening of the connection due to vibration, ensure the reliability of mechanical transmission, and reduce abnormal noise in vehicle use scenarios.

[0062] Optionally, such as Figure 4 As shown, the preload assembly 33 includes a locking nut 331 and a washer assembly 332. One end of the rotating shaft portion 322 opposite to the connecting portion 321 is provided with a threaded structure. The locking nut 331 engages with the threaded structure. The washer assembly 332 is disposed between the locking nut 331 and the first rotating body 31. By tightening the locking nut 331, the frictional damping between the first rotating body 31 and the second rotating body 32 can be easily adjusted to maintain the frictional damping between the first rotating body 31 and the second rotating body 32, and to optimize the feel of angle adjustment in electronic devices. The washer assembly 332 may include elastic washers 3322 spaced apart from the limiting washers 3321 and spaced between the limiting washers 3321. The elastic washers 3322 help compensate for preload loss to provide stable frictional damping and absorb vibration and impact.

[0063] In other embodiments, the first rotating body 31 and the second rotating body 32 can also be coaxially sleeved to achieve relative rotation. For example, the first rotating body 31 is coaxially sleeved on the outside of the second rotating body 32. A pre-tightening assembly 33 is disposed between the inner wall of the first rotating body 31 and the outer wall of the second rotating body 32. The pre-tightening assembly 33 can, for example, be configured to include an elastic structure and a friction structure, wherein the friction structure makes frictional contact with the inner wall of the first rotating body 31 and the outer wall of the second rotating body 32, respectively, and the elastic structure provides a pre-tightening force that causes the friction structure to contact the inner wall of the first rotating body 31 and the outer wall of the second rotating body 32.

[0064] As another embodiment for achieving the relative rotational connection between the first rotating body 31 and the second rotating body 32, a gear-adjustable mechanism can be used, with the rotation axes of the first rotating body 31 and the second rotating body 32 arranged in parallel, and gears capable of meshing are provided in the first rotating body 31 and the second rotating body 32. Even with the presence of gear assembly clearance, considering the form-locking connection between the first rotating body 31 and the first connecting member 1 and the form-locking connection between the second rotating body 32 and the second connecting member 2, it is beneficial to reduce radial runout and axial movement in a vibration environment, thereby reducing abnormal noise.

[0065] In some possible implementations, such as Figure 2 As shown, multiple rotating connection mechanisms 3 are provided, and these multiple rotating connection mechanisms 3 are spaced apart along the rotation axis of the first connector 1. This is beneficial for improving the connection strength and rotation reliability between the first connector 1 and the second connector 2 in vehicle-mounted applications. Figure 2 The embodiment shown includes two rotary connection mechanisms. In other embodiments, such as those requiring enhanced rotary connection strength, a greater number of rotary connection mechanisms 3 may be provided, which will not be elaborated further.

[0066] According to a second aspect of the embodiments of this disclosure, such as Figure 10 As shown, a vehicle-mounted electronic device mounting bracket is also provided, including a bracket body 100, a bracket base 200, and a hinge device 300 connecting the bracket body 100 and the bracket base 200. The bracket body 100 is used to mount electronic devices, the bracket base 200 is used to mount on the vehicle body, and the hinge device 300 is any of the hinge devices described above and has all of their beneficial effects, which will not be elaborated here.

[0067] The bracket body 100 may be provided with a clamping structure 102 for quick installation of electronic devices. The clamping structure 102 may be configured as a movable clamping structure that can move closer or further apart to accommodate electronic devices of different sizes. The bracket base 200 may be provided with a snap-fit ​​structure 202 for quickly installing the mounting bracket onto the vehicle body. Simultaneously, the bracket body 100 may also be provided with a first conductive contact 101 for electrical connection to the electronic device, and the bracket base 200 may also be provided with a second conductive contact 201 for electrical connection to the vehicle, for charging or signal transmission.

[0068] Regarding the connection between the first connector 1 and the bracket body 100, in some possible implementations, such as Figure 11 As shown, the bracket body 100 is provided with a first mounting hole 103, and the first connector 1 is provided with a second mounting hole 121. The vehicle electronic device mounting bracket also includes a connecting shaft 4, which passes through the first mounting hole 103 and the second mounting hole 121 in sequence and is form-locked with the first mounting hole 103 and the second mounting hole 121. This helps to eliminate assembly gaps, thereby eliminating abnormal noises caused by assembly gaps in vehicle use scenarios. For example, the connecting shaft 4 is riveted to the first connector 1 and the bracket body 100 at the mounting hole positions. The connecting shaft 4 may be provided with a toothed structure along the circumferential direction to improve the riveting strength. Optionally, the interference between the connecting shaft 4 and the first mounting hole 103 and the second mounting hole 121 can be configured to be 0.2~0.8 mm.

[0069] Regarding the connection between the second connector 2 and the bracket base 200, in some possible implementations, such as Figure 12 As shown, the second connector 2 is provided with a third mounting hole 221, and the bracket base 200 is provided with a fourth mounting hole 203. The second connector 2 is fixed to the bracket base 200 by bolts that pass through the third mounting hole 221 and the fourth mounting hole 203 in sequence.

[0075] It should be understood that, unless otherwise specifically indicated, features of various embodiments of this disclosure described herein can be combined with each other. As used herein, the term “and / or” includes any one of the relevant listed items and any combination of any two or more; similarly, “at least one of…” includes any one of the relevant listed items and any combination of any two or more.

[0076] It should be understood that, unless otherwise expressly specified and limited, the terms "joining," "attaching," "installing," "connecting," "linking," "fixing," etc., used in the embodiments of this disclosure should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms herein based on the specific circumstances.

[0077] Furthermore, the term "above" as used herein with respect to components, elements, or material layers formed or located "above" a surface may be used to indicate that the component, element, or material layer is "indirectly" positioned (e.g., placed, formed, deposited, etc.) on the surface such that one or more additional components, elements, or layers are arranged between the surface and the component, element, or material layer. However, the term "above" as used with respect to components, elements, or material layers formed or located "above" a surface may also optionally have a specific meaning: that the component, element, or material layer is "directly" positioned (e.g., placed, formed, deposited, etc.) on the surface, for example, in direct contact with the surface.

[0078] Although terms such as “first,” “second,” and “third” may be used herein to describe various components, parts, regions, layers, or sections, these components, parts, regions, layers, or sections are not limited to these terms. Rather, these terms are used only to distinguish one component, part, region, layer, or section from another. Therefore, without departing from the teachings of the examples described herein, the first component, part, region, layer, or section mentioned in the examples may also be referred to as the second component, part, region, layer, or section. Furthermore, the terms “first” and “second” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as “first” or “second” may explicitly or implicitly include at least one of that feature. In the description herein, “a plurality” means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0079] It should be understood that spatial relative terms, such as “above,” “upper,” “below,” and “lower,” are used herein to describe the relationship between one element and another shown in the figures. In addition to the orientation depicted in the figures, these spatial relative terms are also intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as “above” or “upper” relative to another element would be “below” or “lower” relative to that other element. Thus, depending on the spatial orientation of the device, the term “above” encompasses both above and below orientations. Devices may have other orientations (e.g., rotated 90 degrees or in other orientations), and the spatial relative terms used herein should be interpreted accordingly.
