Description

Technical Field

[0001] This application relates to the field of automotive sunroof technology, and in particular to vehicles, roof glass assemblies and their processing methods. Background Technology

[0002] With the development of the automotive industry, more and more car models are choosing glass roofs to enhance visibility. The larger the proportion of glass in the roof, the wider the field of vision. However, in some scenarios, such as hot summer days, direct sunlight entering through the roof glass can affect the comfort of the passengers. Therefore, roof sunshades have emerged. Sunshades can be selectively opened as needed, and they are generally equipped with rails or other structures to allow them to move smoothly in a specific direction. Furthermore, to achieve automatic opening and closing of the sunshade, corresponding drive components are also required. Overall, these functions require a large number of components, which significantly occupies interior space and reduces the space available for passenger movement. Summary of the Invention

[0003] Therefore, it is necessary to address the issue that installing sunshades on the roof occupies a large amount of space, resulting in a reduction in the proportion of activity space for drivers and passengers. A vehicle, a roof glass assembly, and its processing method are provided. Since the hollow tube is integrally formed on the roof glass by setting its own arrangement path, the overall thickness of the roof glass assembly is small, the space occupation rate is low, and thus the proportion of activity space for drivers and passengers is increased.

[0004] A roof glass assembly, comprising:

[0005] Roof glass;

[0006] Two guide rails, both of which are connected to the roof glass, and the two guide rails are arranged at a relative interval;

[0007] Two hollow tubes, each hollow tube having at least a portion of its tube section arranged along the interval direction of the two guide rails, and this portion of the tube section being close to the same end of the two guide rails, with the end of each guide rail close to this portion of the tube section being the first end, one end of one hollow tube being arranged in the guiding direction of the first end of one guide rail, and one end of the other hollow tube being arranged in the guiding direction of the first end of the other guide rail.

[0008] Each of the hollow tubes passes through a drive component mounting position, and each of the hollow tubes is connected to and fixed to the roof glass by an edge injection molding provided along the arrangement path of the hollow tube.

[0009] In one embodiment, the distance B between each hollow tube and the roof glass is no greater than 6.5 mm.

[0010] In one embodiment, the distance B between one end of each hollow tube and the roof glass is 2mm to 6.5mm.

[0011] In one embodiment, the hollow tube is provided with a plurality of process clamping positions, which are arranged sequentially at intervals along the arrangement path of the hollow tube, and the process clamping positions of the hollow tube do not cover the edging.

[0012] In one embodiment, the drive mounting position is located between the two guide rails;

[0013] Each of the hollow tubes includes two straight tube sections that are respectively connected to both sides of the drive unit mounting position, and the straight tube sections are arranged along the interval direction of the two guide rails.

[0014] The other end of each straight pipe segment that mates with the drive component mounting position is connected to a bend in the pipe segment.

[0015] Each hollow tube contains two bends, which are a starting bend and an intermediate bend, and the starting bend of one hollow tube and the intermediate bend of the other hollow tube are located on the same side of the drive unit mounting position.

[0016] One end of the starting bend that is not connected to the straight pipe section is arranged in the guiding direction of a guide rail, and the other end of the starting bend that is not connected to the straight pipe section is arranged in the guiding direction of another guide rail.

[0017] Both of the two intermediate bends are connected to an extended pipe section at the end that is not connected to the straight pipe section. Both extended pipe sections are arranged along the guide direction of the guide rail, and the two guide rails are located between the two extended pipe sections.

[0018] Each of the straight pipe sections, the bent pipe sections, and the extended pipe sections is provided with the process clamping position.

[0019] In one embodiment, both the straight pipe section and the extended pipe section have process clamping positions no more than 30mm away from the end of the bent pipe section;

[0020] And / or, the radius of curvature at any point on the bending path of the pipe bend is not less than 65mm.

[0021] In one embodiment, the guide rail is connected to the roof glass by the integral injection molding of the edging material, and part of the edging material is located between the guide rail and the roof glass, and the thickness F of this part of the edging material is 1mm to 4mm.

[0022] In one embodiment, a groove is formed inside the guide rail, the groove having an opening along the guide rail's guiding direction, and one side wall of the groove is integrally connected to the roof glass via an edge-sealing injection molding. An anti-overflow baffle is provided between the portion of this side wall where the opening is formed and the roof glass, and the edge-sealing is located on the side of the anti-overflow baffle away from this opening.

[0023] In one embodiment, the hollow tube portion is inserted into the guide channel inside the guide rail, the insertion depth G of the hollow tube is greater than 10 mm, and the concentricity error between the hollow tube and the guide channel is ±0.3.

[0024] Alternatively, the hollow tube and the guide rail are arranged at intervals, and the gap between the hollow tube and the guide rail in the guiding direction of the guide rail is 1mm to 3mm.

[0025] In one embodiment, the system further includes a drive unit, a sunshade, and two cables. The drive unit is mounted at the drive unit mounting position. The fixed shaft of the sunshade is arranged along the interval direction of the two guide rails. The fixed shaft is located at the end of the two guide rails away from the first end. The two ends of the movable side of the sunshade can be inserted into the two guide rails respectively and slide within the guide rails. The cables are arranged in the guide passage formed by the corresponding matching of the hollow tube and the guide rails. One end of one cable is connected to one end of the movable side of the sunshade, and one end of the other cable is connected to the other end of the movable side of the sunshade. The drive unit is driven by both cables to drive the cables to slide along their own arrangement path.

[0026] In one embodiment, the coefficient of dynamic friction μ between the hollow tube and the cable is 0.1 to 0.3.

[0027] A method for processing a vehicle roof glass assembly, wherein the vehicle roof glass assembly is the aforementioned vehicle roof glass assembly, the processing method comprising the following steps:

[0028] Press the various process clamping positions of the hollow tube onto the clamping claws of the edge-wrapping mold, and the hollow tube, edge-wrapping mold, and roof glass together form an injection molding space;

[0029] Edge-sealing material is injected into the injection space, and after the edge-sealing material solidifies, it forms the edge of the roof glass assembly.

[0030] In one embodiment, the processing method further includes the following steps:

[0031] Before injecting the edge-sealing material into the injection space, the process also includes plugging the ends of each hollow tube with sealing plugs.

[0032] A vehicle comprising the aforementioned roof glass assembly.

[0033] The above solution provides a vehicle, a roof glass assembly, and its processing method. The area defined by the two guide rails and the hollow tube is the area covered when the sunshade is unfolded. Both ends of the movable side of the sunshade can slide within the two guide rails, and both ends of the movable side can be connected to a cable. The cable can be threaded through the hollow tube. When the drive unit is activated, the cable moves along the hollow tube and guide rails, thereby controlling the opening and closing of the sunshade. Because the hollow tube is injection-molded and fixed to the roof glass along its own path, the overall thickness of the roof glass assembly is relatively small, resulting in low space occupancy and thus increasing the proportion of living space for passengers.

[0050] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0051] like Figure 1 As shown, in some embodiments of this application, a roof glass assembly 10 is provided, including a roof glass 11, two guide rails 12, and two hollow tubes 13. Further, in some embodiments, the roof glass assembly 10 also includes a sunshade 17 and two cables (not shown in the figure).

[0052] The roof glass assembly 10 includes two guide rails 12 that are connected to the roof glass 11, and two hollow tubes 13 that are also connected to the roof glass 11. The two guide rails 12 are arranged at intervals relative to each other, and the interval between the two guide rails 12 is the area covered by the sunshade 17 when it is deployed.

[0053] Each hollow tube 13 has at least a portion of its segment arranged along the interval direction of the two guide rails 12, and this portion of the segment is close to the same end of the two guide rails 12. The end of each guide rail 12 closest to this portion of the segment is the first end, and the other end of the guide rail 12 is the second end. One end of one hollow tube 13 is arranged in the guiding direction of the first end of one guide rail 12, and one end of the other hollow tube 13 is arranged in the guiding direction of the first end of the other guide rail 12. "Arranged in the guiding direction of the first end of the guide rail 12" means that the extension line extending from the first end along the guiding direction of the guide rail 12 passes through this position. Therefore, the cable extending from the first end of the guide rail 12 can be smoothly inserted into its corresponding hollow tube 13. The direction of the cable after transitioning from the guide rail 12 to the hollow tube 13 is determined by the hollow tube 13.

[0054] A hollow tube 13 and a guide rail 12 are matched to form a guide passage, and each guide passage is provided with a pull cable. One end of one pull cable is connected to one end of the movable edge 171 of the sunshade 17, and one end of the other pull cable is connected to the other end of the movable edge 171 of the sunshade 17. When the pull cables move in the guide passage 122, the movable edge 171 of the sunshade 17 slides along the guide direction of the guide rail 12, so that the sunshade 17 can switch between the two states of being open and retracted.

[0055] Furthermore, such as Figures 1 to 5 As shown, each of the hollow tubes 13 passes through a drive component mounting position 111. The drive component mounting position 111 is used to mount drive components 16 such as motors. The cable passing through the hollow tube 13 passes through the drive component mounting position 111 and is in transmission engagement with the drive component 16. When the drive component 16 is activated, it can drive the cable to slide along its own arrangement path; in other words, the cable slides between the hollow tube 13 and the guide rail 12.

[0056] Each hollow tube 13 is injection molded and fixed to the roof glass 11 by an edge band 14 arranged along the arrangement path of the hollow tube 13. For example, the hollow tube 13, the edge band 14 and the roof glass 11 can be integrally injection molded together, or the hollow tube 13 can be first injection molded to the edge band 14, and then the edge band 14 can be bonded to the roof glass 11.

[0057] The area defined by the two guide rails 12 and the hollow tube 13 is the area covered when the sunshade 17 is unfolded. The two ends of the movable edge 171 of the sunshade 17 are respectively inserted into the two guide rails 12 and can slide within them. Both ends of the movable edge 171 of the sunshade 17 can be connected to a pull cable, which can be threaded through the hollow tube 13. When the drive unit 16 is activated, the pull cable can move along the hollow tube 13 and the guide rails 12, thereby controlling the opening and closing of the sunshade 17. Because the hollow tube 13 is injection molded and connected to the edging 14 arranged along its own path and fixed to the roof glass 11, the overall thickness of the roof glass assembly 10 is relatively small, resulting in a low space occupancy rate and thus increasing the proportion of living space for passengers.

[0058] Specifically, in one embodiment, such as Figure 3 As shown, the hollow tube 13 and the edging 14 are injection molded together, eliminating the need for a separate crossbeam to fix the edging 14. The distance B between one end of each hollow tube 13 and the roof glass 11 is no greater than 6.5mm, significantly reducing the thickness of the roof glass assembly 10. Only the edging 14 exists between the hollow tube 13 and the roof glass 11. The thickness B of the edging 14 can be precisely controlled; only the relative position between the hollow tube 13 and the roof glass 11 needs to be accurately defined during injection molding, making it highly feasible.

[0059] More specifically, in some embodiments, the distance B between one end of each hollow tube 13 and the roof glass 11 is 2mm to 6.5mm. For example, the distance B between the end of the hollow tube 13 that forms a guide passage with the guide rail 12 and the roof glass is 2mm to 6.5mm. If the distance B between the hollow tube 13 and the roof glass 11 is too small, there will be less edging material, which may lead to unreliable fixing. If the distance B between the hollow tube 13 and the roof glass 11 is too large, it will result in a larger thickness of the roof glass assembly 10. Therefore, the distance B is limited to the above range to balance connection reliability and thickness requirements.

[0060] If a crossbeam is added and a guide component is further installed on it to limit the cable and ensure that the cable is arranged according to a specified route, the overall thickness of the crossbeam and guide component may need to reach 10mm, resulting in a thicker roof glass assembly. In this application, the hollow tube 13 is injection molded to the edge 14, and the distance B between at least one end of the hollow tube 13 and the roof glass 11 can be controlled within the aforementioned range. This not only reduces the height of the hollow tube 13 but also allows for a reduction in the height of the guide rail 12 corresponding to the hollow tube 13.

[0061] like Figure 3 As shown, in some embodiments, the two hollow tubes 13 are completely enclosed within the edging 14. In a cross-section obtained by taking a section perpendicular to the axial direction of the hollow tube 13, the circle corresponding to the hollow tube 13 is completely located within the edging 14.

[0062] like Figure 4 As shown, in some other embodiments, the two hollow tubes 13 are partially enclosed in the edging 14. In the cross-section obtained by taking a section perpendicular to the axial direction of the hollow tube 13, the circular portion corresponding to the hollow tube 13 is located in the edging 14.

[0063] like Figure 5 As shown, in some embodiments, one hollow tube 13 is fully enclosed in the edging 14, and the other hollow tube 13 is partially enclosed in the edging 14.

[0064] In some embodiments, the coefficient of dynamic friction μ between the hollow tube 13 and the cable is 0.1 to 0.3, so that the cable can slide more smoothly in the hollow tube 13, reducing the noise when the sunshade 17 is opened and closed, and improving the sound quality of the vehicle.

[0065] like Figure 3 As shown, in some embodiments, the inner diameter tolerance of the hollow tube 13 satisfies φA±0.1mm. When the tolerance is met, the distance B between one end of the hollow tube 13 and the roof glass 11 is 2mm to 6.5mm.

[0066] More specifically, such as Figure 1 and Figure 2 As shown, the drive component mounting position 111 is located between the two guide rails 12;

[0067] Each of the hollow tubes 13 includes two straight tube sections 132 that are respectively connected to both sides of the drive unit mounting position 111, and the straight tube sections 132 are arranged along the interval direction of the two guide rails 12.

[0068] The other end of each straight pipe section 132 that is connected to the drive component mounting position 111 is connected to a bend pipe section.

[0069] Each hollow tube 13 includes two bends, namely a starting bend 133 and an intermediate bend 134, and the starting bend 133 and the intermediate bend 134 of one hollow tube 13 are located on the same side of the drive unit mounting position 111.

[0070] One end of the starting bend section 133 that is not connected to the straight section 132 is arranged in the guiding direction of a guide rail 12, and the other end of the starting bend section 133 that is not connected to the straight section 132 is arranged in the guiding direction of another guide rail 12.

[0071] Both of the two intermediate bend pipe sections 134 are connected to an extended pipe section 135 at the end that is not connected to the straight pipe section 132. Both extended pipe sections 135 are arranged along the guiding direction of the guide rail 12, and the two guide rails 12 are located between the two extended pipe sections 135.

[0072] A hollow pipe 13 includes two straight pipe sections 132, an extended pipe section 135, and two bends. An initial bend 133, two straight pipe sections 132, an intermediate bend 134, and an extended pipe section 135 are arranged in sequence and connected along an L-shaped route.

[0073] The initial bend section 133 is arranged correspondingly to the guide rail 12, allowing the cable to transition from the guide rail 12 to the initial bend section 133. Specifically, as shown... Figure 9 and Figure 10 As shown, the initial bend segment 133 can be inserted into the guide channel 122 of the guide rail 12, or the initial bend segment 133 can be spaced apart from the guide rail 12. It should be noted that... Figure 2 In the attached diagram, the straight pipe section 132, the bend pipe section, and the extended pipe section 135 are all completely enclosed in the edging 14. Therefore, at the angle shown in the diagram, except for the process clamping position 131 which is exposed in the edging 14, the other parts of the hollow pipe 13 are located in the edging 14 and cannot be observed.

[0074] The drive component 16 can be injection molded to the edge 14 in a manner similar to that of the hollow tube 13, and then fixed to the drive component mounting position 111 on the roof glass 11.

[0075] Or, such as Figure 1 , Figure 2 and Figure 6 As shown, the drive component 16 is bolted to the edging 14. Figure 6 As shown, the edging 14 is provided with an insert (not shown in the figure), and a bolt (not shown in the figure) passes through the drive member and is threaded into the insert, so that the drive member 16 is fixed on the edging.

[0076] Similarly, such as Figure 7 As shown, in one embodiment, the guide rail 12 is injection molded to and fixed to the roof glass 11, with a portion of the edging material located between the guide rail 12 and the roof glass 11. Figure 8 As shown, in another embodiment, the guide rail 12 is attached to the roof glass 11 by adhesive 18.

[0077] like Figure 7As shown, when the guide rail 12 is integrally injection molded onto the roof glass 11 via the edge 14, during the injection molding process, the guide rail 12 needs to form an injection space together with the roof glass 11, the hollow tube 13, and the edge mold. After the edge material is injected into the injection space, in order to prevent the edge material from overflowing, an anti-overflow baffle 15 can be set between the guide rail 12 and the roof glass 11.

[0078] Specifically, in one embodiment, such as Figure 7 As shown, the anti-overflow baffle 15 is located on the side of the guide rail 12 away from the hollow tube 13. The edging material between the guide rail 12 and the roof glass 11 is blocked by the anti-overflow baffle 15 on the side close to the hollow tube 13.

[0079] Moreover, such as Figure 7 As shown, in some embodiments, a groove 121 is formed inside the guide rail 12, and the groove 121 has an opening along the guiding direction of the guide rail 12. This groove 121 can be used as a guide channel 122, with the cable passing through the groove 121, and both ends of the movable edge 171 of the sunshade 17 located in the groove 121. Of course, the groove 121 can also be used in other situations requiring guidance. One side wall of the groove 121 is integrally injection molded to the roof glass 11 through the edging 14. This side wall is the upper side wall 123 of the guide rail 12. An anti-overflow baffle 15 is provided between the opening on the upper side wall 123 and the roof glass 11, and the edging 14 is located on the side of the anti-overflow baffle 15 away from this opening. The anti-overflow baffle 15 blocks the edging material on the side away from the opening, thereby preventing the edging material from entering the groove 121 during injection molding. Specifically, the anti-overflow baffle 15 can be foam.

[0080] Furthermore, such as Figure 7 As shown, in some embodiments, the thickness F of the edging material located between the guide rail 12 and the roof glass 11 is 1mm to 4mm, which can serve as a connection without causing the roof glass assembly 10 to be too thick due to the large thickness of the edging material.

[0081] like Figure 10 As shown, in some embodiments, the hollow tube 13 is partially inserted into the guide channel 122 within the guide rail 12. The insertion depth G of the hollow tube 13 is greater than 10 mm to ensure a tight fit between the two. The concentricity error between the hollow tube 13 and the guide channel 122 is ±0.3 to prevent abnormal noise when the cable slides at the transition position between the two.

[0082] Alternatively, in other embodiments, such as Figure 9As shown, the hollow tube 13 and the guide rail 12 are arranged at intervals, and the gap between the hollow tube 13 and the guide rail 12 in the guiding direction of the guide rail 12 is 1mm to 3mm. In this way, even if there is a concentricity deviation between the hollow tube 13 and the guide channel 122 in the guide rail 12, the gap between them can absorb this deviation to avoid abnormal noise when the cable slides.

[0083] Furthermore, such as Figure 1 and Figure 2 As shown, in some embodiments, the hollow tube 13 is provided with a plurality of process clamping positions 131, and the plurality of process clamping positions 131 are arranged sequentially at intervals along the arrangement path of the hollow tube 13, and the process clamping positions 131 of the hollow tube 13 do not cover the edging 14.

[0084] like Figure 11 As shown, the process clamping position 131 is used for clamping by the grippers 20. During injection molding of the edge banding 14, the orientation of the hollow tube 13 is determined by the individual grippers 20. For example, multiple grippers 20 are provided on the edge banding mold, and the arrangement path of the multiple grippers 20 is the arrangement path of the hollow tube 13. After the edge banding 14 is completed, the grippers 20 can be removed from the hollow tube 13, so the part previously clamped by the grippers 20 will not be covered by the edge banding 14. When the grippers 20 are clamped on the hollow tube 13, there can be an interference fit between the grippers 20 and the hollow tube 13. In some cases, the specific interference amount E between the two is 0.2mm to 0.5mm.

[0085] like Figure 3 As shown, in one embodiment, all areas of the hollow tube 13 except for the process clamping position 131 are completely enclosed in the edging 14.

[0086] Alternatively, in another embodiment, such as Figure 4 As shown, the areas of the hollow tube 13, excluding the process clamping position 131, are partially enclosed in the edging 14. Furthermore, to ensure that the hollow tube 13 is completely enclosed by the edging 14 and does not fall off, the depth to which the hollow tube 13 is embedded in the edging 14 is greater than the radius of the hollow tube 13.

[0087] Or, as Figure 5 As shown, the area of ​​one hollow tube 13, excluding the process clamping position 131, is partially enclosed in the edging 14, and the area of ​​another hollow tube 13, excluding the process clamping position 131, is completely enclosed in the edging 14.

[0088] like Figure 1 and Figure 2 As shown, each of the straight pipe sections 132, the bent pipe sections, and the extended pipe sections 135 is provided with the process clamping position 131 to ensure that the hollow pipe 13 can be arranged according to the target path.

[0089] In one embodiment, both the straight pipe section 132 and the extended pipe section 135 have process clamping positions 131 located no more than 30 mm from the end of the bent pipe section, to ensure that the bent pipe section can be arranged according to the target bending angle.

[0090] The radius of curvature R at any point on the bending path of the bend is not less than 65mm, to ensure that the cable can slide smoothly in the bend without the cable being obstructed due to excessive change in angle per unit length of the bend.

[0091] In one embodiment, such as Figure 1 As shown, the fixing shaft 172 of the sunshade 17 is arranged along the interval direction of the two guide rails 12. The fixing shaft 172 is located at the end of the two guide rails 12 away from the first end, i.e., the second end. The driving member 16 is in transmission cooperation with both of the cables to drive the cables to slide along their own arrangement path.

[0092] When in the rolled-up state, the sunshade 17 is located on the guide rail 12 at the end away from the drive unit 16. When in the unfolded state, the sunshade 17 covers the area enclosed by the two guide rails 12 and the hollow tube 13.

[0093] Furthermore, in some embodiments of this application, a method for processing a roof glass assembly 10 is provided, wherein the roof glass assembly 10 is the aforementioned roof glass assembly 10, and the processing method includes the following steps:

[0094] like Figure 11 As shown, the various process clamping positions 131 of the hollow tube 13 are pressed onto the clamping claws 20 of the edge-sealing mold, and the hollow tube 13, the edge-sealing mold, and the roof glass 11 together form an injection molding space.

[0095] Edge-sealing material is injected into the injection space, and after the edge-sealing material solidifies, it forms the edge-sealing 14 of the roof glass assembly 10.

[0096] The gripper 20 fixes the hollow tube 13 in the edge-sealing mold, thereby fixing the relative position of the hollow tube 13 with the edge-sealing mold and the roof glass 11 to form an injection molding space.

[0097] Furthermore, such as Figures 12 to 14 As shown, the processing method further includes the following steps:

[0098] Before injecting the edge-binding material into the injection space, the end of each hollow tube 13 is plugged with a sealing plug 30 to prevent the edge-binding material from entering the hollow tube 13.

[0099] like Figure 12 and Figure 14As shown, the hollow tube 13 is interrupted at the drive component mounting position 111. The relative positions of the two hollow tubes 13 at the interruption opening are fixed. The sealing plugs 30 used to seal the two openings are formed together, sealing the two openings at one time, which is convenient for disassembly and assembly.

[0100] like Figure 7 As shown, the processing method further includes the following steps:

[0101] An anti-overflow baffle 15 is provided between the guide rail 12 and the roof glass 11. The anti-overflow baffle 15, the guide rail 12, the roof glass 11, the hollow tube 13 and the edge-sealing mold together form the injection molding space.

[0102] In some embodiments of this application, a vehicle is provided, including the aforementioned roof glass assembly 10. The roof glass assembly 10 can be a sunroof assembly; in other words, the roof glass 11 is a sunroof glass, and the sunroof glass on the vehicle is openable and closable and installed on the roof.

[0103] Optionally, the roof glass 11 can also be a fixed glass fixed to the roof, in which case the relative position between the roof glass 11 and the vehicle body is fixed.

[0104] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0105] Furthermore, where the terms "first" and "second" appear, these terms are 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 with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0106] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0107] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0108] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0109] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0110] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
