Description

Technical Field

[0001] This invention relates to the field of vehicle structure technology, specifically providing a connection structure between a side panel and a skirt, a vehicle body, and a vehicle. Background Technology

[0002] With the rise of new energy vehicles and intensifying competition, vehicle body design has become a key focus of continuous attention and research in the automotive industry. New energy vehicle body design holds a crucial position in automobile manufacturing, affecting aspects such as vehicle performance, safety, and aesthetics. Among these, the connection structure between the side panels and the skirts is a vital component of the body design.

[0003] The side panels are an important component of the vehicle's side profile, forming the overall side outline. Their design directly impacts the vehicle's visual appeal; elegant lines enhance its aesthetics. The skirts, located at the bottom of the vehicle and connected to the side panels, contribute to a more harmonious look. Both the side panels and skirts share the load under the vehicle, improving stability and load-bearing capacity.

[0004] In the prior art, along the width direction of the vehicle, there are usually gaps and discontinuities in the matching area between the side panel and the rear end (towards the rear of the vehicle) of the side panel and the skirt. Along the length direction of the vehicle, the gaps between the front and rear ends of the gaps are uneven, and the rear end area of ​​the side panel and the skirt is prone to gaps, resulting in low matching accuracy.

[0005] Accordingly, there is a need in the art for a connection structure between the side panel and the skirt, a vehicle body, and a vehicle to solve the above problems. Summary of the Invention

[0006] The present invention aims to solve the aforementioned technical problem, namely, the problem of low matching accuracy in the rear end (facing the rear of the vehicle) area of ​​the side panel and the skirt. To this end, the present invention provides a connection structure between the side panel and the skirt. This connection structure is installed in a vehicle and includes both the side panel and the skirt.

[0007] The side panel includes a straight section, a corner section, and a wheel arch section connected in sequence. The straight section has a first sidewall, the corner section has a second sidewall, and the wheel arch section has a third sidewall. The first sidewall and the third sidewall are smoothly connected to the second sidewall. Along the width direction of the vehicle, the third sidewall is located on the side of the first sidewall facing outwards from the vehicle. Along the height direction of the vehicle, the bottom end of the corner section near the wheel arch section is higher than the bottom end of the corner section near the straight section.

[0008] Both the straight section and the corner section are located at the top of the skirt panel.

[0009] In a specific embodiment of the connection structure between the outer side panel and the skirt panel described above, the bottom end of the straight section and the bottom end of the corner section both abut against the top end of the skirt panel. Along the height direction of the vehicle, the skirt panel is higher away from the top end of the straight section than the skirt panel is closer to the top end of the straight section.

[0010] In a specific embodiment of the connection structure between the outer side panel and the skirt panel described above, the maximum vertical distance between the third side wall and its projection on the plane to which the first side wall belongs, along the width direction of the vehicle, is no greater than 60mm.

[0011] In a specific embodiment of the connection structure between the outer side panel and the skirt panel described above, the third side wall is inclined in a direction away from the first side wall along the width direction of the vehicle.

[0012] In a specific embodiment of the connection structure between the outer side panel and the skirt panel described above, the horizontal dimension of the bottom end of the corner segment along the length direction of the vehicle is L, where 150mm≤L≤350mm.

[0013] In a specific embodiment of the connection structure between the outer side panel and the skirt panel described above, the end of the skirt panel away from the straight section is provided with a snap-fit ​​structure that snaps onto the outer side panel.

[0014] In a specific embodiment of the connection structure between the outer side panel and the skirt panel described above, the straight section has a first step, which is connected to the first side wall. Along the length of the vehicle, both the straight section and the first step extend away from the corner section.

[0015] In a specific embodiment of the connection structure between the outer side panel and the skirt panel described above, the corner section has a second step connected to the second side wall, the wheel arch section has a third step connected to the third side wall, and both the first step and the third step are smoothly connected to the second step.

[0016] The present invention also provides a vehicle body. The vehicle body includes the connection structure between the side outer panels and the skirts as described above, as well as fenders.

[0017] The fender is connected to the wheel arch section of the outer side panel.

[0018] The present invention also provides a vehicle. The vehicle includes a body as described above.

[0019] When the above technical solution is adopted, the connection structure between the side panel and the skirt provided by the present invention optimizes the structure of the side panel and the skirt. Specifically, by setting a corner section between the straight section and the wheel arch section of the side panel, the first side wall of the straight section and the third side wall of the wheel arch section can be smoothly connected to the second side wall of the corner section. This creates a smooth connecting arc surface between the straight section and the wheel arch section of the side panel, so that the connection structure between the side panel and the skirt has no obvious discontinuity along the width direction of the vehicle.

[0020] Furthermore, when adopting the above technical solution, the connection structure between the side panel and the skirt provided by the present invention, by setting the third side wall of the wheel arch section to be located on the side of the first side wall of the straight section facing the outside of the vehicle and the bottom end of the corner section near the wheel arch section to be higher than the bottom end of the corner section near the straight section, can eliminate the discontinuity along the width direction of the vehicle in the matching area of ​​the rear end (towards the rear of the vehicle) of the side panel and the skirt, thereby effectively avoiding the problem of gaps in the matching area of ​​the rear end (towards the rear of the vehicle) of the side panel and the skirt, and thus effectively improving the assembly accuracy of the rear end (towards the rear of the vehicle) area of ​​the side panel and the skirt.

[0041] It should be noted that in the description of this invention, terms such as "upper," "lower," "left," "right," "inner," and "outer," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the relevant devices or elements must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, ordinal numbers such as "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0042] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation" and "connection" 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 mechanical connection or an electrical 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 invention according to the specific circumstances.

[0043] Furthermore, it should be noted that in the description of this invention, the terms "up," "down," "front," and "rear" mentioned below refer to the up, down, front, and rear directions of the vehicle. These are generally relative to the vehicle's normal driving state. Specifically, when the vehicle is driving normally, the direction towards the roof is "up," the direction towards the chassis is "down," the direction towards the front of the vehicle is "front," and the direction towards the rear of the vehicle is "rear."

[0044] In this invention, the vehicle can be one of the following: a gasoline-powered vehicle, a new energy vehicle, a natural gas vehicle, or a hybrid vehicle; no limitation is made in this invention.

[0045] In the increasingly competitive automotive market, vehicle body design has become a key competitive factor. A well-designed body can improve a vehicle's acceleration performance, top speed, and other indicators, while also reducing energy consumption and enhancing the driving experience. Furthermore, a well-designed body can give a car an attractive and unique appearance, thereby attracting consumers and increasing its market competitiveness.

[0046] The design between the side panels and the skirts is crucial to vehicle body design, affecting overall performance, safety, aesthetics, and practicality. Therefore, the design of this area must be carefully considered during the body design process to enhance the vehicle's overall competitiveness.

[0047] However, in existing technologies, along the width direction of the vehicle, the matching area between the side panel and the rear end (facing the rear of the vehicle) of the skirt often exhibits discontinuities and gaps. This results in inconsistent gaps along the length direction of the vehicle. Furthermore, under the weight and / or tension of the skirt itself, gaps can easily form at the rear end of the gap between the side panel and the skirt, leading to low matching accuracy and increasing the difficulty of skirt assembly. To address these issues, this invention provides a connection structure between the side panel and the skirt, a vehicle body, and a vehicle itself to solve the aforementioned technical problems.

[0048] like Figure 1 As shown, the present invention proposes a connection structure 100 between a side panel 10 and a skirt panel 20. This connection structure 100 includes a side panel 10 and a skirt panel 20.

[0049] The side panel 10 includes a straight section 11, a corner section 12, and a wheel arch section 13 connected in sequence. The straight section 11 has a first side wall 111, the corner section 12 has a second side wall 121, and the wheel arch section 13 has a third side wall 131. The first side wall 111 and the third side wall 131 are both smoothly connected to the second side wall 121. Along the width direction of the vehicle, the third side wall 131 is located on the side of the first side wall 111 facing the outside of the vehicle. Along the height direction of the vehicle, the bottom end of the corner section 12 near the wheel arch section 13 is higher than the bottom end of the corner section 12 near the straight section 11.

[0050] Both the straight section 11 and the corner section 12 are located at the top of the skirt panel 20.

[0051] In this embodiment, by optimizing the structure of the side panel 10 and the skirt 20, a corner section 12 is provided between the straight section 11 and the wheel arch section 13 of the side panel 10, so that the first side wall 111 of the straight section 11 and the third side wall 131 of the wheel arch section 13 can be smoothly connected to the second side wall 121 of the corner section 12. This creates a smooth connecting arc surface between the straight section 11 and the wheel arch section 13 of the side panel 10, so that the connection structure 100 between the side panel 10 and the skirt 20 has no obvious discontinuity along the width direction of the vehicle.

[0052] Furthermore, in this embodiment, by setting the third sidewall 131 of the wheel arch section 13 to the side of the first sidewall 111 of the straight section 11 facing the outside of the vehicle, and by setting the bottom end of the corner section 12 near the wheel arch section 13 to be higher than the bottom end of the corner section 12 near the straight section 11, the discontinuity along the width direction of the vehicle in the matching area of ​​the rear end (towards the rear of the vehicle) of the side panel 10 and the skirt 20 can be eliminated. This can effectively avoid the problem of the matching area of ​​the rear end (towards the rear of the vehicle) of the side panel 10 and the skirt 20 opening, thereby effectively improving the matching accuracy of the rear end (towards the rear of the vehicle) of the side panel 10 and the skirt 20.

[0053] In one possible implementation, such as Figure 1 As shown, the straight section 11 and wheel arch section 13 of the side outer panel 10 are both connected to the corner section 12. The straight section 11 of the side outer panel 10 is connected to the end of the corner section 12 near the front of the vehicle, and the wheel arch section 13 of the side outer panel 10 is connected to the end of the corner section 12 near the rear of the vehicle.

[0054] Furthermore, such as Figure 1 As shown, the bottom end of the straight section 11 and the bottom end of the corner section 12 both abut against the top end of the skirt 20. Along the height direction of the vehicle, the skirt 20 is further away from the top end of the straight section 11 than the skirt 20 is closer to the top end of the straight section 11.

[0055] In this embodiment, the bottom end of the straight section 11 and the bottom end of the corner section 12 both abut against the top end of the skirt panel 20, which can help enhance the connection between the side outer panel 10 and the skirt panel 20, thereby improving the overall rigidity of the vehicle body, reducing the deformation of the vehicle body during driving, and thus improving the stability and safety of the vehicle.

[0056] In this embodiment, along the height direction of the vehicle, the bottom end of the corner segment 12 near the wheel arch segment 13 is higher than the bottom end of the corner segment 12 near the straight segment 11. Furthermore, the bottom ends of both the straight segment 11 and the corner segment 12 abut against the top of the skirt panel 20. This allows the top of the skirt panel 20 away from the straight segment 11 to be higher than the top of the skirt panel 20 near the straight segment 11. This arrangement creates a gap 100a between the straight segment 11, the corner segment 12, and the skirt panel 20 of the side panel 10. Furthermore, along the height direction of the vehicle, the rear end of the gap 100a is higher than the front end of the gap 100a. This avoids significant discontinuities and misalignments between the side panel 10 and the skirt panel 20 along the width direction of the vehicle, effectively improving the streamlined shape of the gap 100a between the side panel 10 and the skirt panel 20, and enhancing the matching accuracy between the side panel 10 and the skirt panel 20.

[0057] Furthermore, such as Figure 2 As shown, see also Figure 1 Along the width direction of the vehicle, the third sidewall 131 (see...) Figure 1 The maximum vertical distance H1 between the projection of the first sidewall 111 onto the plane to which it belongs is not greater than 60mm.

[0058] In this embodiment, along the width direction of the vehicle, the third sidewall 131 (see...) Figure 1 The arrangement of setting the maximum vertical distance H1 between the wheel arch section 13 and its projection on the plane to which the first sidewall 111 belongs is no greater than 60mm can reduce the wheel arch section 13 (see Figure 1 The third sidewall 131 and the straight section 11 (see) Figure 1 The drop in height of the first sidewall 111 along the width direction of the vehicle is beneficial for lifting the corner section 12 (see...). Figure 1 The smooth connection between the second sidewall 121 of the corner segment 12 and the first sidewall 111 of the straight segment 11, and between the second sidewall 121 of the corner segment 12 and the third sidewall 131 of the wheel arch segment 13, allows for the construction of a smooth arc surface on the second sidewall 121 of the corner segment 12 that connects the first sidewall 111 of the straight segment 11 and the third sidewall 131 of the wheel arch segment 13. This improves the smoothness at that location and allows the second sidewall 121 of the corner segment 12 to have a more streamlined curved surface, further enhancing the appearance of the side panel 10 (see...). Figure 1 ) and skirt board 20 (see Figure 1 Matching accuracy between ).

[0059] In one possible implementation, the value of H1 can be 60mm, 58mm, 55mm, 50mm, 48mm, 45mm, 40mm, 35mm, or 30mm.

[0060] Furthermore, such as Figure 3 As shown, see also Figure 1 Along the width direction of the vehicle, the third sidewall 131 extends away from the first sidewall 111 (see...). Figure 1 The direction of the tilt setting.

[0061] In this embodiment, along the width direction of the vehicle, the third sidewall 131 extends away from the first sidewall 111 (see...). Figure 1 The directional tilt setting can help reduce the height of the wheel arch section 13 (see Figure 1 The third sidewall 131 and the straight section 11 (see) Figure 1 The drop in height of the first sidewall 111 along the width direction of the vehicle is beneficial for further improving the corner section 12 (see Figure 1 The second sidewall 121 (see) Figure 1 The smoothness of the connection between the first sidewall 111 of the straight section 11 and the second sidewall 121 of the corner section 12 and the third sidewall 131 of the wheel arch section 13 is further improved, thereby further enhancing the smoothness of the side panel 10 (see...). Figure 1 ) and skirt board 20 (see Figure 1 Matching accuracy between ).

[0062] In one possible implementation, such as Figure 3 As shown, see also Figure 1 Along the width direction of the vehicle, wheel arch section 13 (see...) Figure 1 The third sidewall 131 is located away from the first sidewall 111 (see...) Figure 1 The angle of inclination of the direction is α, where 3°≤α≤15°. For example, the value of α can be 3°, 4°, 5°, 6°, 7°, 8°, 9°, 10°, 11°, 12°, 13°, 14° or 15°.

[0063] Furthermore, such as Figure 1 As shown, see also Figure 3 Along the length direction of the vehicle X (see Figure 3 The horizontal dimension of the bottom end of corner segment 12 is L, where 150mm ≤ L ≤ 350mm. For example, the value of L can be 150mm, 160mm, 170mm, 180mm, 200mm, 210mm, 220mm, 230mm, 240mm, 250mm, 260mm, 270mm, 280mm, 290mm, 300mm, 320mm, 330mm, 340mm, or 350mm.

[0064] In this embodiment, along the length direction X of the vehicle (see...) Figure 3 If the horizontal dimension L at the bottom of the corner segment 12 is too long, it will reduce the rigidity of the corner segment 12, thereby reducing the rigidity of the side panel 10. This will make the vehicle body more prone to deformation when subjected to external forces, which may negatively affect the safety of the vehicle. If the horizontal dimension L at the bottom of the corner segment 12 is too short, it will be difficult to construct the connecting arc surface for connecting the first side wall 111 of the straight segment 11 and the third side wall 131 of the wheel arch segment 13. This will reduce the streamlinedness of the vehicle body at this position, thereby reducing the aesthetics of the vehicle body. However, by designing the horizontal dimension L of the bottom end of the corner segment 12 between 150mm and 350mm along the length X of the vehicle, both the rigidity and the streamline of the vehicle body can be balanced. This ensures that the side panel 10 has reasonable rigidity, thus ensuring the stability and safety of the vehicle body. At the same time, it also allows the second side wall 121 of the corner segment 12 of the side panel 10 to have a smooth and seamless connecting arc surface. This ensures that the connection structure 100 between the side panel 10 and the skirt 20 has no obvious discontinuity along the width direction of the vehicle, thereby effectively enhancing the sense of layering in the rear area between the side panel 10 and the skirt 20.

[0065] Furthermore, such as Figure 1 As shown, the end of the skirt panel 20 away from the straight section 11 may be provided with a snap-fit ​​structure 21 that snaps into the outer side panel 10.

[0066] In this embodiment, the snap-fit ​​structure 21 provided on the skirt panel 20 allows the skirt panel 20 to snap onto the outer side panel 10, thereby improving the connection strength between the skirt panel 20 and the outer side panel 10. The snap-fit ​​structure 21 provided on the end of the skirt panel 20 away from the straight section 11 allows the end of the skirt panel 20 away from the straight section 11 to snap onto the outer side panel 10, thereby improving the connection strength between the end of the skirt panel 20 away from the straight section 11 and the outer side panel 10. This ensures that the skirt panel 20 is firmly connected to the outer side panel 10 as a whole, preventing the gap 100a between the end of the skirt panel 20 away from the straight section 11 and the rear end of the outer side panel 10 from being too large. This effectively prevents the gap between the end of the skirt panel 20 away from the straight section 11 and the rear end of the outer side panel 10, thereby improving the assembly accuracy of the outer side panel 10 and the skirt panel 20 in the rear end region of the outer side panel 10.

[0067] In one possible implementation, such as Figure 1As shown, the snap-fit ​​structure 21 can be as follows: a support frame (not shown in the figure) is provided on the side wall of the skirt panel 20 facing the outer side panel 10 at the end away from the straight section 11. The support frame is provided with a buckle (not shown in the figure) protruding towards the outer side panel 10. Furthermore, the outer side panel 10 has a through hole (not shown in the figure) at the position corresponding to the buckle. The buckle of the skirt panel 20 passes through the through hole so that the end of the skirt panel 20 away from the straight section 11 can be snapped onto the outer side panel 10.

[0068] In some examples, such as Figure 1 As shown, the support frame (not shown in the figure) is fixedly connected to the side wall of the skirt panel 20 facing the outer side panel 10 at the end away from the straight section 11. The support frame and the buckle (not shown in the figure) can be integrally formed.

[0069] In one possible implementation, such as Figure 1 As shown, along the height direction of the vehicle, the vertical distance between the snap-fit ​​structure 21, located at the end of the skirt 20 furthest from the straight section 11, and the rearmost end of the skirt 20 is H2, where 24mm ≤ H2 ≤ 65mm. For example, the value of H2 can be 24mm, 25mm, 28mm, 30mm, 32mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm, or 65mm.

[0070] Furthermore, such as Figure 4 As shown, see also Figure 1 and Figure 3 Straight section 11 (see Figure 1 It has a first step 112, which is connected to a first sidewall 111, along the length direction X of the vehicle (see...). Figure 3 The straight section 11 and the first step 112 are both along the path away from the corner section 12 (see...). Figure 1 Extend in the direction of ).

[0071] In this embodiment, straight segment 11 (see...) Figure 1 The first step 112 is beneficial for improving the side panel 10 (see...) Figure 1 The rigidity near the front of the vehicle effectively prevents the side panel 10 from deforming during the painting and baking process, thus ensuring the accuracy and stability of the vehicle body dimensions. At the same time, this design can also reduce quality problems of the side panel 10 during the painting and baking process and improve production efficiency.

[0072] In one possible implementation, such as Figure 4 As shown, see also Figure 1 Side panel 10 (see) Figure 1 It also includes the fourth sidewall 14 and the straight section 11 (see Figure 1The first step 112, away from the first sidewall 111, is connected to the bottom of the fourth sidewall 14.

[0073] In this embodiment, straight segment 11 (see...) Figure 1 The first step 112 can effectively reduce the side panel 10 (see...) Figure 1 The fourth side wall 14 of the side panel 10 is dimensional along the height direction of the vehicle, which can effectively improve the rigidity of the fourth side wall 14 of the side panel 10, thereby preventing the fourth side wall 14 of the side panel 10 from deforming during the painting and baking process.

[0074] In one possible implementation, such as Figure 4 As shown, see also Figure 1 The first step 112 of the straight section 11 is set towards the roof of the vehicle.

[0075] In some examples, such as Figure 4 As shown, along the height direction of the vehicle, the end of the first step 112 of the straight section 11 away from the first sidewall 111 is higher than the end of the first step 112 of the straight section 11 that is close to the first sidewall 111.

[0076] Furthermore, such as Figure 4 As shown, see also Figure 1 and Figure 2 Along the width direction of the vehicle, straight section 11 (see...) Figure 1 The first step 112 of the straight section 11 has a certain width. By adjusting the width of the first step 112, the position of the first sidewall 111 of the straight section 11 in the width direction of the vehicle can be adjusted, thereby adjusting the wheel arch section 13 (see...). Figure 1 The third sidewall 131 (see) Figure 1 The maximum vertical distance H1 between it and its projection on the plane to which the first sidewall 111 of the straight section 11 belongs (see...) Figure 2 ).

[0077] In one possible implementation, such as Figure 4 As shown, along the width direction of the vehicle, the projected width of the first step 112 of the straight section 11 on the horizontal plane is W, where 2mm ≤ W ≤ 15mm. For example, the value of W can be 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm or 15mm.

[0078] In some examples, such as Figure 4 As shown, along the width direction of the vehicle, the projected width of the first step 112 of the straight section 11 on the horizontal plane is W, where 3mm ≤ W ≤ 8mm. For example, the value of W can be 3mm, 4mm, 5mm, 6mm, 7mm, or 8mm.

[0079] Furthermore, such as Figure 1 As shown, see also Figure 4 The corner segment 12 has a second step 122 connected to the second sidewall 121, the wheel arch segment 13 has a third step 132 connected to the third sidewall 131, and the first step 112 (see...) Figure 4 Both the third step 132 and the second step 122 are smoothly connected.

[0080] In this embodiment, the first step 112 of the straight section 11 and the third step 132 of the wheel arch section 13 are smoothly connected to the second step 122 of the corner section 12, which can make the second step 122 of the corner section 12 have a smooth arc surface, which can further improve the streamlinedness of the corner section 12 of the side outer panel 10, enhance the sense of layering of the body, and further improve the assembly accuracy between the side outer panel 10 and the skirt 20.

[0081] In one possible implementation, such as Figure 1 As shown, see also Figure 3 The second step 122 of the corner section 12 can effectively reduce the height of the fourth side wall 14 of the side panel 10 along the vehicle's height direction and length direction X (see...). Figure 3 The dimensions of the corner section 12 are adjusted to effectively improve the rigidity of the fourth side wall 14 of the outer side panel 10 in this area. Unlike the prior art where the fourth side wall 14 of the outer side panel 10 is provided with wrinkle-absorbing grooves to improve the rigidity of this area, the second step 122 of the corner section 12 allows the fourth side wall 14 of the outer side panel 10 to have reasonable rigidity without the need for wrinkle-absorbing grooves. This ensures the surface flatness and aesthetics of the fourth side wall 14, and also reduces subsequent repair work and improves production efficiency.

[0082] In one possible implementation, such as Figure 1 As shown, the second step 122 of the corner section 12 has an arc surface facing the roof. This arrangement makes it easier to form the corner section 12 of the side panel 10 and can effectively prevent the corner section 12 of the side panel 10 from cracking.

[0083] In some examples, such as Figure 1 As shown, the radius of curvature R of the second step 122 of the corner segment 12 is greater than or equal to 60 mm. For example, the value of R can be 60 mm, 65 mm, 70 mm, 75 mm, 80 mm, 83 mm or 85 mm.

[0084] See Figure 1-4 The present invention also proposes a vehicle body. The vehicle body includes a connection structure 100 between the side outer panel 10 and the skirt 20 as described in the above embodiment, and a fender (not shown in the figure).

[0085] The fender (not shown in the figure) is connected to the wheel arch section 13 of the side panel 10.

[0086] In one possible implementation, the fender (not shown) is connected to the end of the wheel arch section 13 of the side panel 10 away from the corner section 12.

[0087] See Figure 1-4 The present invention also proposes a vehicle. The vehicle includes the body as described in the above embodiments.

[0088] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of the present invention.
