[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application.

[0033] It is to be understood that where an element such as a layer, region or substrate is described as being "on" another element, it can be directly on the other element or intervening elements can also be present. Where an element such as a layer, region or substrate is described as being "connected" to another element, it can be directly connected to the other element or intervening elements can also be present. Where an element such as a layer, region or substrate is described as being "positioned on" another element, it can be directly positioned on the other element or intervening elements can also be present. Relative terms such as "on", "above", "upper", "lower", "horizontal", "vertical", "left", "right", and the like as used herein are for the purpose of illustration only and are not intended to limit the scope of the present application.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0035] The embodiments described below and the features in the embodiments can be combined with each other unless otherwise specified.

[0036] With the current development of automobiles towards more integration, the front engine compartment of the vehicle is becoming more and more empty, especially the empty area under the engine compartment, which results in no effective shielding at the bottom. Thus, when the vehicle is driven on a rainy day or a dirty road, the mud and other pollutants are easy to be thrown into the engine compartment, causing the engine compartment to be dirty, which affects the appearance of the vehicle and the functional reliability of the parts in the engine compartment.

[0037] In the prior art, a bottom guard plate is usually installed at the bottom of the vehicle, and a wheel cover can also be provided on the side of the vehicle to protect the vehicle from the mud and other pollutants splashed or thrown up by the wheels on various driving surfaces. However, due to the complexity of the vehicle structure, the bottom guard plate and the wheel cover also have certain limitations when providing protection for the vehicle, and cannot provide sufficient shielding area. For example, the movement range of the vehicle suspension swing arm, the layout of the wire harness, and the position of the steering gear, etc. limit the wheel cover and the bottom guard plate from providing sufficient shielding area. This means that in some areas of the vehicle, these protection components can not completely shield the mud or other pollutants, so that some parts of the vehicle can be exposed and contaminated.

[0038] To solve the above problems, the embodiments of the present application provide a splash guard and a vehicle. Please refer to FIGS. 1 to 9 for a detailed description of the embodiments of the present application.

[0039] Embodiments

[0040] FIGS. 1 and 2 show a vehicle 100 according to an embodiment of the present application.

[0041] The vehicle 100 can be, for example, a fuel vehicle (such as a gasoline vehicle, a diesel vehicle, etc.), an electric vehicle (such as a pure electric vehicle, a fuel cell vehicle), or a hybrid electric vehicle.

[0042] The vehicle 100 comprises a chassis 110 and a vehicle body 120 connected to the chassis 110. It is to be noted that only parts of the chassis 110 and the vehicle body 120 are shown in dotted lines in FIGS. 1 and 2.

[0043] Referring to FIG. 3, the chassis 110 mainly comprises a subframe 111, a steering system 112 and the like. The vehicle body 120 comprises a vehicle body longitudinal beam 121.

[0044] The vehicle 100 is further provided with a splash guard 130. The splash guard 130 is connected between the chassis 110 and the vehicle body 120, and is used to solve the problem of contamination of the engine compartment of the vehicle 100 by mud and the like splashed up by the vehicle 100 or thrown up by the wheels, and to ensure the aesthetic appearance of the vehicle 100 and the functional reliability of the components in the engine compartment of the vehicle 100.

[0045] The splash guard 130 in the embodiment will be described below with reference to FIGS. 4 to 9.

[0046] Referring to FIGS. 4 and 5, the splash guard 130 in the embodiment comprises a side plate body 10 and a lower plate body 20.

[0047] The side plate body 10 has a first end D1 and a second end D2 opposite to each other in a first direction A1. When the splash guard 130 is installed on the vehicle 100, the first direction A1 of the splash guard 130 is parallel to a height direction Z of the vehicle 100 (allowing a certain deviation, for example, the included angle between the first direction A1 and the height direction Z of the vehicle 100 is within 10°). The first end D1 is above the height direction Z of the vehicle 100, and the second end D2 is below the height direction Z of the vehicle 100 (see FIG. 1).

[0048] The first end D1 of the side plate body 10 is used to be connected to the vehicle body 120 of the vehicle 100, for example, to the vehicle body longitudinal beam 121 of the vehicle body 120. The lower plate body 20 is bent to be connected to the second end D2 of the side plate body 10, and is used to be connected to the chassis 110 of the vehicle 100.

[0049] In the embodiment, the lower plate body 20 being bent to be connected to the side plate body 10 can mean that the side plate body 10 and the lower plate body 20 are both formed by stamping and bending or other bending processes from the same plate material, and the side plate body 10 and the lower plate body 20 are respectively located on both sides of the bending line. The following bending connections can be understood accordingly.

[0050] When the splash guard 130 is installed on the vehicle 100, the outer surface of the side plate body 10 faces or approximately faces the outer side of the width direction Y of the vehicle 100, and the outer surface of the lower plate body 20 approximately faces downward (i.e., faces the ground) along the first direction A1. In this way, the splash guard 130 can simultaneously achieve the mud blocking effect on the side and the bottom, and reduce the pollution of the vehicle body by mud and the like splashed up or thrown up by the vehicle 100 on the bottom or the side of the vehicle 100.

[0051] Continuing to refer to FIG. 4 and FIG. 5, in the present embodiment, the lower plate body 20 comprises a first connecting plate 21, a surrounding plate 23 and a second connecting plate 22, the first connecting plate 21 and the second connecting plate 22 are arranged at intervals along the second direction A2, the surrounding plate 23 is connected between the first connecting plate 21 and the second connecting plate 22, and is concave inward along the first direction Al towards the first end D1 to define an avoiding passage T1. The avoiding passage T1 extends along the third direction A3 to allow the object 114 of the vehicle 100 (such as the steering tie rod 114a of the vehicle 100, the wire harness, etc.) to pass through, and to avoid the movement envelope of the front suspension lower control arm assembly of the vehicle 100. The structures of the chassis 110 of the vehicle 100 can be seen in FIG. 3.

[0052] The second direction A2 is perpendicular or obliquely intersected with the first direction Al. In the present embodiment, the second direction A2 is parallel to the length direction X (or the front-rear direction) of the vehicle 100. The third direction A3 is parallel to the width direction Y of the vehicle 100.

[0053] In the lower plate body 20, the first connecting plate 21 and the second connecting plate 22 are respectively connected to two positions of the chassis 110 of the vehicle 100 along the second direction A2, for example, the first connecting plate 21 is connected to the subframe 111 of the chassis 110, and the second connecting plate 22 is connected to the front suspension lower control arm assembly 113 of the chassis 110. Details can be seen in FIG. 3.

[0054] Continuing to refer to FIG. 4 and FIG. 5, the side plate body 10 comprises a first branch plate region 11, a second branch plate region 12 and a base plate region 13. The first branch plate region 11 and the second branch plate region 12 are respectively connected to the base plate region 13 on the side close to the second end D2, and are respectively located on the two sides of the avoiding passage T1 along the second direction A2. The first branch plate region 11 is bent and connected to the first connecting plate 21, and the second branch plate region 12 is bent and connected to the second connecting plate 22.

[0055] Optionally, the substrate region 13 extends substantially along the first direction Al, the first and second side plate regions 11 and 12 extend along directions oblique to the first direction Al, and the distance between the first and second side plate regions 11 and 12 gradually increases in a direction away from the substrate region 13 along the first direction Al, so that the first and second side plate regions 11 and 12 and the substrate region 13 of the side plate body 10 are connected to form an inverted "Y" shape structure. In addition to the reinforcement of the lower part of the side plate body 10 by the lower plate body 20, the lower half of the splash guard 130 with higher strength can be reliably connected to the chassis 110, ensuring reliable installation of the splash guard 130 on the vehicle 100; at the same time, the upper half of the splash guard 130 with lower strength (mainly the part of the substrate region 13 close to the first end Dl) is connected to the vehicle body 120, which is beneficial to absorbing the travel difference of the vehicle body 120 relative to the chassis 110 in the height direction Z (such as the heave motion of the vehicle body 120 relative to the chassis 110 when the vehicle 100 wades through a pit).

[0056] As shown mainly in FIG. 5, the splash guard 130 further comprises a plurality of first reinforcing ribs 41, which are sequentially and spacedly distributed along the intersection line (i.e. the bending line) of the lower plate body 20 and the side plate body 10, and each first reinforcing rib 41 is connected between the part of the side plate body 10 close to the lower plate body 20 and the lower plate body 20. By reinforcing the connection between the lower part of the side plate body 10 and the lower plate body 20 through the first reinforcing ribs 41, the lower half of the splash guard 130 close to the chassis 110 can have greater rigidity, while the upper half close to the vehicle body 120 can have smaller rigidity, so as to ensure that the splash guard 130 has sufficient structural strength when subjected to external impact and is not damaged or excessively deformed, and at the same time, when the vehicle body 120 and the chassis 110 move relative to each other, the splash guard 130 can absorb the travel difference caused by the relative motion through its softer (or smaller rigidity) upper half structure.

[0057] Optionally, in a direction close to the first end Dl along the first direction Al, the width of the substrate region 13 along the second direction A2 gradually decreases. In this way, the width of the lower part of the substrate region 13 is greater than that of the upper part, further ensuring the greater rigidity of the lower part and the smaller rigidity of the upper part of the splash guard 130.

[0058] Continuing to refer to FIG. 4 and FIG. 5, in the present embodiment, the surrounding plate 23 is in a U shape opening towards the second end D2, and the first connecting plate 21 and the second connecting plate 22 are respectively bent and connected to two opposite sides of the surrounding plate 23 along the second direction A2. The surrounding plate 23, the first branch plate region 11 and the first connecting plate 21 are respectively bent and connected to form one leg structure of the splash guard 130, and the surrounding plate 23, the second branch plate region 12 and the second connecting plate 22 are respectively bent and connected to form another leg structure of the splash guard 130. The two leg structures are respectively connected to the chassis 110 in a forked manner, and are respectively connected by three plate portions in different directions, so as to have a high structural rigidity, and the two leg structures are connected to the chassis 110 in a reliable and fixed manner.

[0059] Among the plurality of first reinforcing ribs 41, at least part of the first reinforcing ribs 41 are connected between the base plate region 13 and the surrounding plate 23, at least part of the first reinforcing ribs 41 are connected between the first branch plate region 11 and the first connecting plate 21, and at least part of the first reinforcing ribs 41 are connected between the second branch plate region 12 and the second connecting plate 22, so as to enhance the connection rigidity of the lower half of the side plate body 10 and the lower plate body 20 along the bending line.

[0060] Continuing to refer to FIG. 4 and FIG. 5, in the present embodiment, the splash guard 130 further comprises a bent plate body 30, and the bent plate body 30 is bent and connected between the first branch plate region 11 and the first connecting plate 21. Specifically, the edge of the first branch plate region 11 away from the second branch plate region 12 is a first edge L1, the edge of the first connecting plate 21 away from the second connecting plate 22 is a second edge L2, and the bent plate body 30 is bent and connected between the first edge L1 and the second edge L2. By connecting the first branch plate region 11 and the first connecting plate 21 through the bent plate body 30, the structural rigidity of the first branch plate region 11 and the first connecting plate 21 can be further enhanced.

[0061] The direction of the bent plate body 30 is different from that of the side plate body 10, and can also provide a supplementary splash-proof effect. For example, in the present embodiment, the plate surface of the side plate body 10 faces the third direction A3 (i.e. the width direction Y of the vehicle 100), mainly providing a lateral splash-proof function; the plate surface of the lower plate body 20 faces the first direction A1 (i.e. the height direction Z of the vehicle 100), mainly realizing a bottom splash-proof function; and the plate surface of the bent plate body 30 faces obliquely to the first direction A1 and the third direction A3, and the bent plate body 30 generally faces obliquely downward, which can be used to splash the pollutants obliquely downward.

[0062] Optionally, at least one second reinforcing rib 42 is connected at the corner of the bending plate body 30 and the first supporting plate area 11 to reinforce the connecting rigidity of the bending plate body 30 and the first supporting plate area 11. Similarly, at least one third reinforcing rib 43 is connected at the corner of the bending plate body 30 and the first connecting plate 21 to reinforce the connecting rigidity of the bending plate body 30 and the first connecting plate 21. In this way, the first supporting plate area 11, the first connecting plate 21 and the bending plate body 30 are connected by bending and are reinforced by the reinforcing ribs, and the structure formed by the three has high rigidity, which facilitates reliable connection of the first connecting plate 21 to the chassis 110 of the vehicle 100.

[0063] Referring to FIG. 5, in the embodiment, the splash guard 130 further includes a first folded edge 44 and a second folded edge 45.

[0064] The first folded edge 44 is folded from the first side edge line L3 in the same bending direction as the lower plate body 20. The first side edge line L3 includes an edge line of the first supporting plate area 11 away from the first connecting plate 21 and an edge line of the bending plate body 30 away from the surrounding plate 23. At least part of the first reinforcing rib 41 and the second reinforcing rib 42 extend to the first folded edge 44 to further reinforce the structural strength of the connecting area of the first supporting plate area 11, the first connecting plate 21 and the bending plate body 30.

[0065] Similarly, the second folded edge 45 is folded from the second side edge line L4 in the same bending direction as the lower plate body 20. The second side edge line L4 includes an edge line of the second supporting plate area 12 away from the surrounding plate 23 and an edge line of the second connecting plate 22 away from the surrounding plate 23. At least part of the first reinforcing rib 41 extends to the second folded edge 45 to further reinforce the structural strength of the connecting area of the second supporting plate area 12, the second connecting plate 22 and the surrounding plate 23.

[0066] Referring to FIG. 5, the splash guard 130 of the embodiment further includes an auxiliary reinforcing structure 46. The auxiliary reinforcing structure 46 includes a reinforcing convex ring 46a and a plurality of connecting ribs 46b. The reinforcing convex ring 46a protrudes from the surface of the first supporting plate area 11. Part of the connecting ribs 46b are respectively connected between the reinforcing convex ring 46a and the first reinforcing rib 41, part of the connecting ribs 46b are respectively connected between the reinforcing convex ring 46a and the second reinforcing rib 42, and part of the connecting ribs 46b are respectively connected between the reinforcing convex ring 46a and the first folded edge 44. The auxiliary reinforcing structure 46 can play an auxiliary reinforcing role.

[0067] FIG. 6 is an enlarged view of A in FIG. 3, and FIG. 7 is a perspective view of the splash guard 130 of the embodiment from another angle. The connection structure of the splash guard 130 to the chassis 110 and the vehicle body 120 will be described below with reference to FIGS. 6 and 7.

[0068] Referring to FIG. 6 and FIG. 7, in the embodiment, the first connecting plate 21 is provided with a first connecting portion 213 for connecting to the sub-frame 111 of the chassis 110. The second connecting plate 22 is provided with a second connecting portion 223 for connecting to the front suspension lower control arm assembly 113 of the chassis 110. The base plate region 13 of the side plate body 10 is provided with a third connecting portion 14 near the first end D1 for connecting to the body side rail 121 of the vehicle body 120.

[0069] Optionally, the first connecting portion 213 comprises a first connecting hole K1 formed in the first connecting plate 21, the second connecting portion 223 comprises a second connecting hole K2 formed in the second connecting plate 22, and the third connecting portion 14 comprises a third connecting hole K3 formed in the base plate region 13. During connection, the first connecting plate 21 can be fixedly connected to the chassis 110 by a first connecting member 141 (such as a bolt) passing through the first connecting hole K1, the second connecting plate 22 can be fixedly connected to the chassis 110 by a second connecting member 142 (such as a bolt) passing through the second connecting hole K2, and the base plate region 13 can be fixedly connected to the outside of the body side rail 121 by a third connecting member 143 (such as a bolt).

[0070] In the embodiment, in the second direction A2, the third connecting portion 14 is located between the first connecting portion 213 and the second connecting portion 223, and the first connecting portion 213, the second connecting portion 223 and the third connecting portion 14 are approximately in the shape of an isosceles triangle with the third connecting portion 14 as the apex. In this way, when the vehicle body 120 moves up and down relative to the chassis 110, the force exerted by the vehicle body 120 on the third connecting portion 14 of the splash guard 130 can be transmitted to the first connecting portion 213 and the second connecting portion 223 on both sides respectively, so that the force on the splash guard 130 is more balanced, and the splash guard 130 is more easily deformed elastically in the first direction A1 to absorb the travel difference caused by the relative movement between the chassis 110 and the vehicle body 120.

[0071] Optionally, the second connecting hole K2 is a strip-shaped hole extending in the second direction A2 to accommodate the deviation between the interval between the first connecting hole K1 and the second connecting hole K2 and the interval between the two connecting points on the chassis 110, thereby reducing the requirement for structural precision and the difficulty of assembly.

[0072] Continuing to refer to FIG. 6 and FIG. 7, in the embodiment, the first end D1 of the side plate body 10 of the splash guard 130 is provided with a guide structure 15 formed by bending and extending away from the lower plate body 20. Specifically, the guide structure 15 is formed by bending and extending the base plate region 13 of the side plate body 10 near the first end D1, so that the guide structure 15 is approximately in the shape of a circular arc.

[0073] In the connected state, the base plate region 13 of the side plate body 10 is superimposed on the outer side surface of the vehicle body longitudinal beam 121, and the guide structure 15 is bent to extend away from the outer side surface of the vehicle body longitudinal beam 121.

[0074] In the mounting of the splash guard 130 in the present embodiment, the first connecting plate 21 and the second connecting plate 22 of the splash guard 130 are first fixedly connected to the chassis 110, and after the vehicle body 120 is assembled to the chassis 110, the base plate region 13 of the splash guard 130 is fixedly connected to the vehicle body longitudinal beam 121. This assembly mode connection can facilitate the assembly of the splash guard 130 to a greater extent, and can meet the durability requirements of the assembled vehicle 100.

[0075] In the process of assembling the vehicle body 120 to the chassis 110, the outwardly bent guide structure 15 can meet the guiding requirements of the assembly with the vehicle body longitudinal beam 121, and the guide structure 15 can absorb the cumulative tolerance in the width direction Y of the vehicle 100 during the assembly process when the vehicle body 120 is assembled to the chassis 110. In other words, in the process of assembling the vehicle body 120 to the chassis 110, the upper part (mainly the base plate region 13) of the side plate body 10 of the splash guard 130 can be elastically deformed under the guidance of the guide structure 15 to adapt to the position tolerance of the vehicle body 120 and the splash guard 130 in the width direction Y of the vehicle 100, so as to ensure that after the vehicle body 120 is assembled, the base plate region 13 of the splash guard 130 can be attached to the outer side surface of the vehicle body longitudinal beam 121, so that the base plate region 13 is fixedly connected to the vehicle body longitudinal beam 121.

[0076] Optionally, the first connecting hole K1 is located at one end of the first connecting plate 21 away from the side plate body 10, and the second connecting hole K2 is located at one end of the second connecting plate 22 away from the side plate body 10, so as to improve the deformation capability of the side plate body 10 in the width direction Y of the vehicle 100.

[0077] Fig. 8 is an enlarged view of B in Fig. 7, and Fig. 9 is an enlarged view of C in Fig. 7. Figs. 8 and 9 respectively show the structure of the lower surface (i.e. the surface facing the chassis 110) of the first connecting plate 21 and the second connecting plate 22.

[0078] Referring to FIG. 8, in the embodiment, the first connecting plate 21 comprises a first base plate segment 211 and a first sunken plate segment 212. The first base plate segment 211 is connected to the side plate body 10 by bending. The first sunken plate segment 212 is connected to the first base plate segment 211 and sunken relative to the first base plate segment 211 in a direction away from the first end D1, so that the first surface P1 of the first sunken plate segment 212 away from the first end D1 and the second surface P2 of the first base plate segment 211 away from the first end D1 are staggered in the first direction A1. The first connecting plate 21 further comprises a first reinforcing structure 50, which comprises a first protruding edge 51, a second protruding edge 52 and a plurality of fourth reinforcing ribs 53. The first connecting hole K1 is formed in the first sunken plate segment 212. The first protruding edge 51 and the second protruding edge 52 are respectively protruded on the first surface P1 and spaced around the outer periphery of the first connecting hole K1. The plurality of fourth reinforcing ribs 53 are radially arranged around the first connecting hole K1. Some of the fourth reinforcing ribs 53 extend from the first surface P1 to the second surface P2 at one end and extend through the second protruding edge 52 and connect to the first protruding edge 51 at the other end. Some other fourth reinforcing ribs 53 are reinforced between the first protruding edge 51 and the second protruding edge 52. The first protruding edge 51, the second protruding edge 52 and the plurality of fourth reinforcing ribs 53 are connected as a whole, and the surfaces on the side away from the first surface P1 of the three are coplanar, which are used to cooperate with a supporting surface of the chassis 110. This structure can improve the thickness and structural strength of the first connecting plate 21 around the first connecting hole K1, and can avoid or slow down the damage of the first connecting plate 21 at the connection with the chassis 110.

[0079] Referring to FIG. 9, the second connecting plate 22 comprises a second base plate segment 221 and a second sunken plate segment 222. The second base plate segment 221 is connected to the side plate body 10 by bending. The second sunken plate segment 222 is connected to the second base plate segment 221 and sunken relative to the second base plate segment 221 in a direction away from the first end D1, so that the third surface P3 of the second sunken plate segment 222 away from the first end D1 and the fourth surface P4 of the second base plate segment 221 away from the first end D1 are stepped in the first direction A1. The second connecting plate 22 further comprises a second reinforcing structure 60, which comprises a third protruding edge 61, a fourth protruding edge 62 and a plurality of fifth reinforcing ribs 63. The second connecting hole K2 is formed in the second sunken plate segment 222. The third protruding edge 61 and the fourth protruding edge 62 are respectively formed on the third surface P3 and spaced around the outer periphery of the second connecting hole K2. The plurality of fifth reinforcing ribs 63 are radially formed around the second connecting hole K2. Some of the fifth reinforcing ribs 63 extend from the third surface P3 to the fourth surface P4 at one end and extend through the fourth protruding edge 62 and connect to the third protruding edge 61 at the other end. Some other fifth reinforcing ribs 63 are connected between the third protruding edge 61 and the fourth protruding edge 62. The third protruding edge 61, the fourth protruding edge 62 and the plurality of fifth reinforcing ribs 63 are connected as a whole, and the surfaces on the side away from the third surface P3 of the three are coplanar, which are used to match a supporting surface of the chassis 110. This structure can improve the thickness and structural strength of the second connecting plate 22 around the second connecting hole K2, and can avoid or slow down damage to the second connecting plate 22 at the connection with the chassis 110.

[0080] In summary, the splash guard 130 in the embodiment has a structure that the lower half has greater structural rigidity and the upper half has smaller structural rigidity, so as to ensure that it has sufficient strength to withstand external impact and can absorb the travel difference of the relative movement between the vehicle body 120 and the chassis 110.

[0081] In addition, in the splash guard 130, the side plate body 10 located outside the vehicle body longitudinal beam 121 of the vehicle body 120 in the width direction Y of the vehicle 100, and the lower plate body 20 located between the chassis 110 and the vehicle body longitudinal beam 121 of the vehicle 100 in the height direction Z of the vehicle 100, can take into account the splash guard effect in the width direction Y and the height direction Z of the vehicle 100. The avoidance passage T1 of the lower plate body 20 can also meet the avoidance requirements of the target piece 114 (such as the steering tie rod 114a) of the vehicle 100.

[0082] At the same time, the guide structure 15 of the splash guard 130 is beneficial to guiding the deformation of the splash guard 130 to give way when the vehicle body 120 is combined to the chassis 110, and absorbing the cumulative tolerance in the width direction Y of the vehicle 100 during assembly.

[0083] In addition, the splash guard 130 is designed as a separate component from the wheel cover of the vehicle 100, and the design is more free and less affected by the assembly process. Moreover, the splash guard 130 can increase the shielding area of the vehicle 100 cabin in the width direction Y and the height direction Z as much as possible, and make up for the problem that the bottom apron and the side wheel cover of the existing vehicle 100 bottom cannot provide sufficient shielding area due to the influence of the suspension swing arm motion envelope, wire arrangement, steering arrangement, etc.

[0084] Finally, it should be noted that the use position of the splash guard 130 in the embodiment is not limited to the position near the front wheels as shown, and it can also be arranged near the rear wheels or other suitable positions of the vehicle 100. For the splash guard 130 arranged in different positions, it can be adapted by referring to the technical concept described above.

[0085] The above embodiments are only used to illustrate the technical solutions of the present application and not to limit it, although the present application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced without departing from the spirit and scope of the present application.
