Detailed Implementation
[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0019] In the description of this specification, the references to terms such as "embodiment," "one embodiment," "some implementations," "exemplary," and "one implementation," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or implementation is included in at least one embodiment or implementation of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or implementation. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.
[0020] The terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
[0021] like Figures 1 to 5 As shown, the main reference is... Figure 4 As shown, this utility model provides an exterior rearview mirror mounting structure, which includes a door inner panel 1, a window frame reinforcing plate 2, and a reinforcing block 3. Along the vehicle width direction, the reinforcing block 3 is located between the window frame reinforcing plate 2 and the door inner panel 1. The reinforcing block 3 includes a block body 31 and a snap-fit structure 32 provided at one end of the block body 31. The block body 31 abuts against the window frame reinforcing plate 2 and the door inner panel 1 respectively. One of the window frame reinforcing plate 2 and the door inner panel 1 is provided with a snap-fit mating part 21 that snaps into the snap-fit structure 32. The block body 31 is provided with a first mounting hole 318, the window frame reinforcing plate 2 is provided with a second mounting hole 22, and the door inner panel 1 is provided with a third mounting hole 11. The first mounting hole 318, the second mounting hole 22, and the third mounting hole 11 are connected to each other to form an exterior rearview mirror mounting hole.
[0022] Specifically, the window frame reinforcement plate 2 is arranged between the inner door panel 1 and the outer door panel. The inner door panel 1 forms the internal skeleton of the door, used to install functional components such as the window regulator and locking mechanism. The outer door panel forms the outer wall of the door, consistent with the vehicle body appearance. The inner door panel 1 and the outer door panel are typically stamped sheet metal parts. The window frame reinforcement plate 2 is located at the upper part of the door, below the exposed area of the glass, and is mainly used to improve the rigidity and torsional resistance of the upper part of the door. The accompanying drawings of this specification show the exterior rearview mirror mounting structure for the left front door, and the left front door adopts a frameless glass design. In addition, in some scenarios, the door also includes an exterior handle reinforcement plate, which is located between the window frame reinforcement plate 2 and the outer door panel, and is connected to the inner door panel 1.
[0023] The inner door panel 1, reinforcing block 3, window frame reinforcing plate 2, and outer door panel are distributed sequentially from the inside to the outside in the vehicle width direction. The block body 31 abuts against the inner door panel 1 and the window frame reinforcing plate 2 at both ends in the vehicle width direction, and is engaged with the snap-fit part 21 of the inner door panel 1 or the window frame reinforcing plate 2 through a snap-fit structure 32 provided at one end of the block body 31. The accompanying drawings of this specification show the snap-fit part 21 provided on the window frame reinforcing plate 2, and the reinforcing block 3 being engaged with the snap-fit part 21 of the window frame reinforcing plate 2 through the snap-fit structure 32.
[0024] It should be noted that the window frame reinforcing plate 2 and the inner door panel 1 are connected, usually by welding or riveting. During the assembly of the exterior rearview mirror mounting structure, the snap-fit structure 32 of the reinforcing block 3 snaps into, for example, the snap-fit mating part 21 of the window frame reinforcing plate 2. Then, the window frame reinforcing plate 2 and the inner door panel 1 are connected. By using the block body 31 to abut against the window frame reinforcing plate 2 and the inner door panel 1 at both ends in the vehicle width direction, a stable support can be formed between the window frame reinforcing plate 2 and the inner door panel 1. This helps improve the overall rigidity of the exterior rearview mirror mounting structure and avoids suspension or localized stress concentration.
[0025] It should be noted that the exterior rearview mirror typically includes the mirror body and the corresponding bracket. The exterior rearview mirror mounting hole is usually used to install the corresponding bracket. This part can adopt relevant technologies, such as fasteners passing through the exterior rearview mirror mounting hole and connecting to the bracket. In this way, the axial locking force of the fastener can ensure that the block body 31 abuts against the window frame reinforcing plate 2 and the inner door panel 1 respectively, ensuring the reliability of the bracket installation.
[0026] Thus, in this embodiment of the exterior rearview mirror mounting structure, the reinforcing block 3 is positioned between the window frame reinforcing plate 2 and the inner door panel 1, with the block body 31 of the reinforcing block 3 abutting against both. Since the inner door panel 1 and the window frame reinforcing plate 2 are connected by welding or riveting, the three can form a stable load-bearing system, effectively dispersing the vibration load and torque stress generated by the exterior rearview mirror during driving, improving the structural rigidity of the door in the installation area of the exterior rearview mirror, and avoiding the problem of rearview mirror wobbling due to insufficient door rigidity. Furthermore, the block body 31 is provided with a first mounting hole 318, and the second mounting hole 22 of the window frame reinforcing plate 2 and the third mounting hole 11 of the inner door panel 1 are all connected to the first mounting hole 318, and the three together constitute the exterior rearview mirror mounting hole. The exterior rearview mirror is installed through the mounting hole. When the fastener passes through the mounting hole and is connected to the bracket of the exterior rearview mirror, the axial connection force of the fastener can further ensure the contact reliability between the block body 31 at the first mounting hole 318 and the window frame reinforcing plate 2 and the inner door panel 1, respectively, and further ensure the stability of the load-bearing system formed by the three. At the same time, the reinforcing block 3 has a snap-fit structure 32 at one end of the block body 31. The snap-fit structure 32 is snap-fitted to the snap-fit mating part 21 provided on the window frame reinforcing plate 2 or the inner door panel 1, so as to realize the detachable connection of the reinforcing block 3. There is no need to weld between the reinforcing block 3 and the window frame reinforcing plate 2 or the inner door panel 1, which can avoid the problems of heat deformation and stress concentration caused by welding, and also improve the assembly efficiency.
[0027] Overall, the exterior rearview mirror mounting structure of this utility model can improve the structural rigidity of the car door in the exterior rearview mirror mounting area, thereby avoiding the wobbling of the exterior rearview mirror. In addition, the exterior rearview mirror mounting structure is simple in structure and easy to manufacture and assemble.
[0028] like Figure 3 and Figure 4 As shown, in some optional embodiments, the reinforcing block 3 further includes a positioning post 33 connected to the block body 31, and one or more of the window frame reinforcing plate 2 and the inner door panel 1 are provided with positioning holes 23, and the positioning post 33 is accommodated in the positioning hole 23.
[0029] Specifically, the positioning post 33 and the positioning hole 23 typically serve as assembly guide structures, used to guide the reinforcing block 3 accurately into its predetermined position during installation. At least one of the window frame reinforcing plate 2 and the inner door panel 1 has a corresponding positioning hole 23. When the reinforcing block 3 is installed, the positioning post 33 is inserted into the positioning hole 23. One or more positioning posts 33 can be provided as needed. An appropriate clearance is maintained between the positioning post 33 and the positioning hole 23 to absorb manufacturing tolerances between components and ensure smooth assembly.
[0030] Thus, the design of the positioning post 33 and the positioning hole 23 can improve the assembly accuracy and connection reliability of the exterior rearview mirror mounting structure. At the same time, under the condition of vehicle vibration, the positioning hole 23 can also contact with the positioning block 3, which can suppress the slight shaking of the reinforcing block 3 to a certain extent and enhance the stability of the overall structure.
[0031] like Figure 9 As shown, in a further optional embodiment, the snap-fit structure 32 includes a snap-fit post 321 and a snap-fit protrusion 322 disposed on the snap-fit post 321. The length direction of the snap-fit post 321 extends along the axial direction of the positioning post 33. The snap-fit protrusion 322 abuts against the snap-fit mating part 21 along the length direction of the snap-fit post 321. The block body 31 is connected to the positioning post 33 at least at one end where the snap-fit post 321 is located.
[0032] The accompanying drawings in this description only schematically show the case where the block body 31 of the reinforcing block 3 is provided with a snap-fit structure 32 and a positioning post 33 at one end near the window frame reinforcing plate 2. The following description will use this as an example to illustrate the content of this utility model. However, it should be understood that another positioning post 33 may also be provided at the end of the block body 31 away from the snap-fit structure 32.
[0033] Specifically, the snap-fit action direction of the snap-fit structure 32 is aligned with the insertion direction of the positioning post 33 into the positioning hole 23, forming a unidirectional assembly path. This "positioning first, snap-fit later" assembly sequence avoids problems such as damage to the snap fasteners or misalignment of the mounting holes caused by manual misalignment. Operators or automated equipment only need one linear push-in action to complete the insertion of the positioning post 33 and the snap-fit structure 32, without the need for additional rotation or pressing steps, significantly shortening the assembly cycle. At the same time, the snap-fit protrusion 322 and the snap-fit mating part 21 abut against each other axially, effectively withstanding the pull-out force and vibration load from the exterior rearview mirror, preventing loosening and falling off.
[0034] like Figure 6 , Figure 8 and Figure 9 As shown, the main reference is... Figure 8 and Figure 9 In a further optional embodiment, the positioning post 33 is a cylindrical structure. The cylindrical wall of the cylindrical structure is provided with a plurality of opening slots 331 extending along its axial direction. The plurality of opening slots 331 divide the cylindrical wall into a plurality of columnar structures 332. Part of the columnar structures 332 is used to form a locking post 321. The locking protrusion 322 is located on the side of the locking post 321 opposite to the inner cavity of the cylindrical structure. The locking mating part 21 is located at the edge of the positioning hole 23.
[0035] Specifically, the positioning post 33 is a cylindrical structure, and the cross-sectional shape of the cylindrical structure can be circular or rectangular, etc. The cylindrical wall is provided with multiple opening slots 331 extending along the axial direction. These opening slots 331 make the cross-sectional shape of the cylindrical structure discontinuous, dividing the cylindrical wall into several independent columnar structures 332 in the circumferential direction. This allows the columnar structures 332 to have a certain elastic deformation capability in the radial direction. When it is inserted into the positioning hole 23, the columnar structure 332 can undergo slight outward expansion or inward contraction to adapt to the hole diameter tolerance, so as to achieve smooth assembly and reliable fit.
[0036] Among all the columnar structures 332, some of the columnar structures 332 are used to form locking posts 321, which bear the axial limiting function. On the outer side of these locking posts 321 (i.e. the side away from the inner cavity of the cylindrical structure), there are locking protrusions 322. The locking protrusions 322 can be in the form of barbs, beveled bosses or elastic locking teeth, etc. In this case, a section of the edge of the positioning hole 23 forms the locking engagement part 21. When the positioning post 33 is inserted into the positioning hole 23, the locking protrusions 322 of some columnar structures 332 (this part of the columnar structures 332 forms the locking posts 321) can be locked and engaged with the locking engagement part 21 on the edge of the positioning hole 23. The other columnar structures 332 still retain the original positioning function of the positioning post 33.
[0037] In this way, integrating the snap-fit structure 32 onto the cylindrical structure with positioning function avoids the space occupation and structural complexity caused by adding an additional independent snap-fit structure 32, which is conducive to reducing the material used in the reinforcing block 3 and the lightweight design of the reinforcing block 3. At the same time, the elasticity of the opening groove 331 is not only conducive to self-alignment during the insertion process, but also provides continuous restoring force after snap-fit is completed, so that the snap-fit protrusion 322 and the snap-fit mating part 21 on the edge of the positioning hole 23 remain in tight contact, effectively resisting the loosening tendency caused by vehicle vibration.
[0038] like Figure 9As shown, in a further optional embodiment, when the positioning post 33 is a cylindrical structure, the block body 31 is provided with a groove 35 and a missing part 36. The groove 35 is located at the end of the block body 31 that is connected to the cylindrical structure and is provided corresponding to the inner cavity of the cylindrical structure. The missing part 36 is located at the circumferential edge of the cylindrical structure and is provided corresponding to the locking post 321. The two adjacent opening slots 331 on both sides of the locking post 321 extend away from the locking protrusion 322 and are respectively connected to the groove 35 and the missing part 36.
[0039] Specifically, Figures 6 to 9 In the middle, the missing part 36 is a through hole, which extends circumferentially along the cylindrical structure, and its two ends are respectively connected to two open slots 331. The groove 35 corresponds to the inner cavity of the cylindrical structure, that is, it is equivalent to slotting the block body 31 in the inner cavity of the cylindrical structure to form the groove 35, which is equivalent to further deepening the inner cavity of the cylindrical structure.
[0040] Thus, the groove 35, the missing part 36, and the opening groove 33 are connected in a plane perpendicular to the locking post 321. After the three are connected, they generally present an annular groove-shaped area around the locking post 321 on the block body 31. The part of the block body 31 surrounded by this annular groove-shaped area is connected to the root of the locking post 321. This surrounded part can undergo elastic deformation with the locking post 321, which is equivalent to increasing the effective length of the locking post 321, thereby improving its bending stiffness, elastic deformation capacity and fatigue resistance.
[0041] In this design, the missing portion 36 is a through hole, which facilitates the manufacturing and forming of the reinforcing block 3. For example, when the reinforcing block 3 is an injection molded part, it facilitates the arrangement of the core-pulling slider. However, the missing portion 36 may not be a through hole; it may be a recessed groove in the block body 31.
[0042] The area corresponding to the missing part 36 arranged circumferentially along the cylindrical structure does not need to be set to surround the cylindrical structure. The area corresponding to the missing part 36 arranged circumferentially along the cylindrical structure usually only needs to meet the communication requirements with the opening slot 33. In this way, the setting of the missing part 36 only enhances the elasticity of the locking post 321, without affecting the connection strength between the columnar structure 332 without the locking protrusion 322 and the block body 31.
[0043] In a further alternative embodiment, the distance from the free end of the columnar structure 332 constituting the locking post 321 to the block body 31 can be less than the distance from the free end of other columnar structures 332 to the block body 31. This ensures that the positioning post 33 is inserted into the positioning hole 23 first, and then the locking post enters the positioning hole 23.
[0044] In a further optional embodiment, the end of the snap-fit protrusion 322 away from the block body 31 is provided with a guide surface, which can be a guide slope or a curved surface. This ensures that the snap-fit protrusion 322 can smoothly pass through the positioning hole 23 and snap into the snap-fit mating part 21.
[0045] Unlike the above-mentioned scheme where the snap-fit structure 32 is integrated into the cylindrical structure, in some optional embodiments not shown in the figures, the snap-fit posts 321 and positioning posts 33 located at the same end of the block body 31 are spaced apart. In this case, the same function can be achieved, but it occupies a relatively larger space and uses relatively more material.
[0046] In some alternative embodiments, the block body 31 is provided with a weight reduction structure.
[0047] The specific configuration of the weight reduction structure is not a limitation and will be illustrated later. It usually involves removing some material from the interior of the reinforcing block 3 or in non-critical load-bearing areas through various means, thereby reducing the weight of the reinforcing block 3 itself and ensuring structural rigidity.
[0048] like Figure 6 and Figure 7 As shown, in a further optional embodiment, the weight reduction structure includes at least one of a honeycomb structure 311 and a weight reduction groove 312; the honeycomb structure 311 is arranged at least at one end of the block body 31 away from the snap-fit structure 32, and the weight reduction groove 312 is arranged at least at one end of the block body 31 where the snap-fit structure 32 is provided.
[0049] The following description uses the example of the block body 31 having a honeycomb structure 311 only at the end opposite to the snap-fit structure 32 and a weight-reducing groove 312 only at the end with the snap-fit structure 32 to illustrate the content of this utility model, but it should be understood that it is not limited to this.
[0050] like Figure 7 As shown, the honeycomb structure 311 typically includes multiple weight-reducing holes 316 and a partition structure 317 for separating the weight-reducing holes 316. The structural forms of the weight-reducing holes 316 and the partition structure 317 are not limited. For example, the block body 31 has a cavity at one end away from the snap-fit structure 32, and the partition structure 317 is arranged in the cavity to divide the cavity into multiple weight-reducing holes 316.
[0051] The honeycomb structure 311 has the advantages of high specific stiffness and energy absorption and vibration reduction. It is arranged at least at one end of the block body 31 away from the snap-fit structure 32. It can support and distribute the load, effectively improve the local bending resistance without significantly increasing the mass, and ensure the overall bending stiffness requirements of the block body 31. The space at the end of the block body 31 with the snap-fit structure 32 is relatively limited. Arranging the weight reduction groove 312 at this end can achieve weight reduction while avoiding an overly complex weight reduction structure.
[0052] like Figure 7 As shown, in a further optional embodiment, the partition structure 317 located at one end of the block body 31 away from the snap-fit structure 32 includes a first partition 314, the position of which corresponds to the position of the snap-fit structure 32.
[0053] like Figure 7 As shown, taking the case where the snap-fit structure 32 is integrated into the positioning post 33 as an example, in the vehicle width direction, the projection of the cylindrical structure on a certain vertical plane (this vertical plane is perpendicular to the vehicle width direction) coincides with the projection of the first partition 314, thereby realizing that the position of the first partition 314 corresponds to the position of the snap-fit structure 32.
[0054] Specifically, among the multiple weight reduction holes 316, the positions of at least two holes correspond to the positions of the cylindrical structure. These at least two holes are separated by a first partition 314. The structural form of the first partition 314 is not limited. For example, its projection on a certain vertical plane (which is perpendicular to the vehicle width direction) can be circular, rectangular, or straight.
[0055] like Figure 7 As shown, exemplarily, the first partition 314 divides a cavity of an approximately cylindrical structure into two weight-reducing holes 316.
[0056] Thus, although the first partition 314 is located at the end of the block body 31 of the reinforcing block 3 away from the snap-fit structure 32, through the structural correspondence, the first partition 314 can provide structural reinforcement at the connection between the block body 31 and the snap-fit structure 32, and can transfer the stress from the snap-fit part to other positions. As one of the load-bearing ribs of the honeycomb structure 311, the first partition 314 can ensure the local stiffness of the reinforcing block 3 without increasing the external dimensions.
[0057] In addition, the partition structure 317 of the honeycomb structure 311 may also include a grid-like reinforcing rib structure composed of multiple hexagonal, quadrilateral or polygonal units. Each weight-reducing hole 316 obtained by the partition structure 317 extends along the vehicle width direction, thereby facilitating the manufacturing and forming of the honeycomb structure 311, for example, facilitating the formation of the reinforcing block 3 by injection molding.
[0058] like Figure 8 As shown, in a further optional embodiment, the end of the weight-reducing groove 312 located at the same end of the snap-fit structure 32 extends to the circumferential surface of the block body 31 and forms a through opening 315 on the circumferential surface of the block body 31. The snap-fit structure 32 is arranged on one or more sides of the weight-reducing groove 312, and the first mounting hole 318 is arranged on one or more sides of the weight-reducing groove 312.
[0059] Specifically, the weight-reducing groove 312 is located at the same end as the snap-fit structure 32. It is formed by the surface of the block body 31 near the snap-fit structure 32 recessed towards the other end. The number of weight-reducing grooves 312 can be one or more, which can be set as needed. The weight-reducing groove 312 has a through-hole 315 formed on the circumferential surface of the block body 31, which facilitates the manufacturing and forming of the weight-reducing groove 312. The through-hole 315 also enables the block body 31 to have a certain elastic deformation capacity, preventing the block body 31 from cracking due to local stress concentration. The snap-fit structure 32 is arranged on one side or multiple times of the weight-reducing groove 312. The arrangement of the weight-reducing groove 312 does not affect the arrangement of the snap-fit structure 32.
[0060] like Figure 8 As shown, exemplarily, the weight-reducing groove 312 includes a first groove and a second groove. The second groove extends generally horizontally, with through openings 315 formed at both ends. The first groove extends generally vertically, with a through opening 315 at its upper end and communicating with the second groove at its lower end. Thus, first mounting holes 318 are arranged on both sides of the first groove, and a snap-fit structure 32 is arranged on at least one side of the first groove. The second groove has both first mounting holes 318 and snap-fit structure 32 arranged below it. In this way, the two weight-reducing grooves 312 are arranged in a roughly T-shape, achieving significant weight reduction without affecting the structural performance of the block body 31 at the locations of the first mounting holes 318 and snap-fit structure 32.
[0061] like Figure 8 As shown, in some optional embodiments, the block body 31 is provided with a support rib 34 at one end near the snap-fit structure 32, and the support rib 34 abuts against the window frame reinforcement plate 2 or the inner panel 1 of the door where the snap-fit part 21 is located at the edge of the snap-fit part 21.
[0062] The support rib 34 can be a local reinforcing structure located near the snap-fit structure 32 on the block body 31. It is usually a strip-shaped, ring-shaped, or radially protruding rib that extends radially or circumferentially. One end is connected to the block body 31, and the other end extends outward, corresponding to the edge area of the snap-fit part 21. When the reinforcing block 3 is assembled in place, the free end of the support rib 34 forms surface contact or line contact with the sheet metal surface around the snap-fit part 21 (located on the window frame reinforcing plate 2 or the inner door panel 1), achieving mechanical abutment.
[0063] Thus, on the one hand, the supporting rib 34 at the edge of the snap-fit part 21 enables the reinforcing block 3 to abut against the window frame reinforcing plate 2 or the inner door panel 1 where the positioning hole 23 is located. This transforms the contact between the reinforcing block 3 and the window frame reinforcing plate 2 or the inner door panel 1 from a point contact or gap state that might have existed before into a stable support state, effectively improving the load-bearing capacity between the interfaces. Especially when the vehicle is subjected to high-frequency vibration and wind load impact during operation, the supporting rib 34 can continuously provide reaction force to suppress micro-amplitude relative movement, thereby reducing the risk of abnormal noise and fatigue damage. On the other hand, the supporting rib 34 is located near the snap-fit structure 32, which can share the locking pressure and external load from the snap-fit structure 32, reduce the stress concentration at the snap-fit part, and extend the service life of the reinforcing block 3.
[0064] In the above embodiments, optionally, the window frame reinforcing plate 2 and the inner door panel 1 form a cavity, and the reinforcing block 3 is located inside the cavity.
[0065] For example, the window frame reinforcing plate 2 and the door inner panel 1 are connected by either welding or riveting, and the two form the aforementioned cavity at the installation area of the exterior rearview mirror. The reinforcing block 3 is arranged in the cavity, and both ends of the block body 31 abut against the window frame reinforcing plate 2 and the door inner panel 1, respectively. Here, the cavity may have partial openings as needed, which is not a limitation.
[0066] Thus, the window frame reinforcing plate 2 and the inner door panel 1 form a cavity, which itself has a certain effect of local stiffness enhancement. Furthermore, by arranging reinforcing blocks 3 in the cavity, the structural stiffness of the door in the area where the exterior rearview mirror is installed can be further improved.
[0067] In the above embodiments, the reinforcing block 3 can be an injection molded part. It can be made entirely of plastic material or it can have embedded inserts. This facilitates the manufacturing and shaping of the reinforcing block 3 and is beneficial for large-scale mass production.
[0068] like Figure 4 As shown, optionally, the inner wall of the first mounting hole 318 is provided with a reinforcing structural layer 313.
[0069] The implementation method of the reinforcing structural layer 313 is not limited. This specification takes the reinforcing block 3 as an injection molded part as an example. In this case, the reinforcing structural layer 313 can be inserted as an insert during the injection molding of the reinforcing block 3, or it can be obtained by using a two-color injection molding process.
[0070] In some alternative embodiments, the cross-sectional area of the first mounting hole 318 may be greater than or equal to the cross-sectional area of the second mounting hole 22, and the cross-sectional area of the first mounting hole 318 may be greater than or equal to the cross-sectional area of the third mounting hole 11, so as to avoid the hole diameter of the first mounting hole 318 being too small and affecting the insertion of the fastener.
[0071] An embodiment of this utility model also provides a car door, which includes the exterior rearview mirror mounting structure described in the above embodiment.
[0072] An embodiment of this utility model also provides a vehicle that includes the door described in the above embodiment.
[0073] The door and the vehicle have all the beneficial effects of the exterior rearview mirror mounting structure, which will not be elaborated here.
[0074] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
