Description

Technical Field

[0001] This application relates to the field of instrument panel assembly technology, and more particularly to an instrument panel assembly assembly structure and vehicle. Background Technology

[0002] The instrument panel assembly is a critical component of a vehicle, typically comprising the instrument panel itself and the instrument panel crossbeam assembly that supports it. Currently, the instrument panel crossbeam assembly is generally assembled to the front bulkhead assembly of the vehicle body using auxiliary tooling. However, after the auxiliary tooling is removed, the instrument panel assembly is prone to tipping over, resulting in poor assembly stability. Utility Model Content

[0003] This application provides an instrument panel assembly structure and vehicle, which aims to improve the problem that the instrument panel assembly is prone to tipping over during assembly, resulting in poor assembly stability.

[0004] In a first aspect, this application discloses an instrument panel assembly structure for use in a vehicle. The instrument panel assembly structure includes a front bulkhead assembly and an instrument panel crossbeam assembly arranged sequentially along the length of the vehicle.

[0005] The instrument panel crossbeam assembly includes an instrument crossbeam and a front bulkhead bracket. The instrument crossbeam is connected to the front bulkhead assembly at both ends along the width direction of the vehicle. The front bulkhead bracket is connected to the instrument crossbeam and extends at least partially toward the front bulkhead assembly.

[0006] The front bulkhead assembly has a support member at a corresponding position on the front bulkhead bracket, and the support member is connected to the front bulkhead bracket.

[0007] In this embodiment, due to the provision of a support member, the connection between the front bulkhead bracket and the support member, and the connection between the two ends of the instrument crossbeam and the front bulkhead assembly, the front bulkhead assembly can provide Z-axis support to the instrument crossbeam assembly from three points, thereby forming a stable Z-axis support surface. This effectively avoids the problem of the instrument panel assembly flipping during assembly and helps to improve the assembly stability of the instrument panel assembly.

[0008] Optionally, at least a portion of the support member protrudes towards the front bulkhead bracket to form a boss;

[0009] The front bulkhead bracket overlaps the boss.

[0010] In this embodiment, due to the presence of a boss, during the assembly of the instrument panel assembly—specifically, as the auxiliary tooling pushes the instrument panel assembly toward the front bulkhead assembly—the front bulkhead bracket can continuously approach and overlap the boss. This simplifies the assembly process while providing reliable support for the front bulkhead bracket, thereby reducing the assembly difficulty and improving the assembly efficiency of the instrument panel assembly.

[0011] Optionally, the front bulkhead bracket includes: a connector and an overlap member;

[0012] The connector is connected to the instrument crossbeam;

[0013] The lap joint is located at the end of the connector away from the instrument beam, and the lap joint overlaps the boss.

[0014] In this embodiment, by providing an overlapping member, a stable force transmission path can be formed between the instrument panel crossbeam assembly and the front bulkhead assembly through the connection between the overlapping member and the connecting member, and the overlap between the overlapping member and the boss. That is, part of the weight of the instrument panel assembly can be transferred to the overlapping member through the connecting member, and then from the overlapping member to the boss for dispersion, thereby ensuring reliable support for the instrument panel assembly. Furthermore, compared to the connecting member directly overlapping the boss, using a dedicated overlapping member allows for better adaptation between the connecting member and the boss, thereby improving the ease and stability of assembly between the front bulkhead bracket and the boss.

[0015] Optionally, the boss has a first overlapping surface, which extends along a first direction, and the first direction is set at an angle to the length direction of the vehicle.

[0016] The connector has a second overlapping surface, which is parallel to and abuts against the first overlapping surface.

[0017] In this embodiment, the extension direction (i.e., the first direction) of the first lap surface is set at an angle to the length direction of the vehicle, meaning the first lap surface is inclined relative to the horizontal plane. This has two advantages: firstly, for bosses formed by stamping, the inclined first lap surface reduces the processing difficulty of the boss; secondly, the inclined first lap surface acts as a guide during assembly, allowing operators to easily guide the lapped parts to the accurate position along the inclined direction, thereby improving the assembly accuracy of the instrument panel assembly and reducing its assembly difficulty. By having the first and second lap surfaces parallel and abutting each other, the contact area between the boss and the lapped parts can be increased, resulting in a more even distribution of force, further improving the assembly stability of the instrument panel assembly.

[0018] Optionally, the angle between the first direction and the length direction of the vehicle is 25° to 35°.

[0019] In the embodiments of this application, when the angle between the first direction and the length direction of the vehicle is 25° to 35°, the boss can have both good support and guiding effects, while at the same time, the processing difficulty of the boss can be reduced.

[0020] Optionally, the overlapping member includes: an overlapping portion and an arc-shaped guide portion;

[0021] The overlapping portion is connected to the connector and overlaps with the boss;

[0022] The arc-shaped guide portion is disposed at one end of the overlapping portion away from the instrument crossbeam, and the arc-shaped guide portion is used to guide the overlapping portion to cooperate with the boss.

[0023] In this embodiment, due to the provision of the arc-shaped guide, when there is a Z-direction (i.e., the height direction Z of the vehicle) misalignment between the front bulkhead bracket and the boss, the contact between the arc-shaped surface of the arc-shaped guide and the boss can play a role in guiding and correcting the assembly of the overlapping parts, thereby improving the assembly accuracy and assembly efficiency of the front bulkhead bracket and the boss.

[0024] Optionally, the overlapping member further includes a flange portion, which is disposed on the side of the overlapping member close to the connector, and the flange portion is connected to the connector.

[0025] In this embodiment, the flange is provided, and the flange is connected to the connector, which increases the connection area between the overlapping part and the connector, thereby improving the connection reliability between the overlapping part and the connector, and further improving the assembly stability of the instrument panel assembly.

[0026] Optionally, the instrument crossbeam includes: a crossbeam body and two end plates;

[0027] The crossbeam body extends along the width direction of the vehicle;

[0028] The two end plates are disposed at both ends of the beam body in the extension direction, and the two end plates are respectively connected to the front bulkhead assembly.

[0029] In this embodiment, the end plates enable a reliable connection between the instrument panel beam assembly and the front bulkhead assembly. Furthermore, the support members on the front bulkhead and the end plates on the two A-pillars form a triangular Z-axis support surface, effectively preventing the instrument panel assembly from flipping during assembly and further improving its assembly stability.

[0030] Optionally, the end plate is provided with one of a positioning protrusion or a positioning hole, and the front bulkhead assembly is provided with the other of the positioning protrusion or the positioning hole at a position corresponding to the end plate, wherein the positioning protrusion passes through the positioning hole.

[0031] In this embodiment, the presence of positioning protrusions and positioning holes allows for the restriction of movement of the instrument panel assembly in both the length and width directions during assembly. Furthermore, the positioning protrusions and holes provide Z-axis support. Additionally, operators only need to insert the positioning protrusions into the positioning holes to complete the positioning assembly, significantly improving the ease of assembly.

[0032] Secondly, embodiments of this application also disclose a vehicle including the aforementioned dashboard assembly structure.

[0033] In this embodiment of the application, by setting an instrument assembly assembly structure that can prevent overturning, the assembly stability of the instrument assembly can be improved, so that the instrument assembly can be reliably assembled with other vehicle components (such as auxiliary instruments, door trim panels, etc.), which is beneficial to improving vehicle production efficiency and product quality.

[0048] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0049] Currently, to improve human-machine interface operations and save assembly time on the main assembly line, parts such as instrument panels are assembled with the instrument panel crossbeam assembly on the instrument panel sub-assembly line to form the instrument panel assembly. Since the instrument panel crossbeam assembly is the main supporting structure of the instrument panel assembly, the assembly stability of the instrument panel assembly depends on the installation stability of the instrument panel crossbeam assembly and the vehicle body.

[0050] like Figure 1 As shown, in related technologies, the instrument panel assembly assembly structure includes a front bulkhead assembly 2 and an instrument panel crossbeam assembly 1 arranged sequentially along the length X of the vehicle. The instrument panel crossbeam assembly 1 includes an instrument crossbeam 11 and two end plates 112. The two end plates 112 are respectively disposed at both ends of the instrument crossbeam 11 along the width Y of the vehicle, and the end plates 112 are connected to the front bulkhead assembly 2. Specifically, the end plates 112 are provided with positioning holes 1121, and the front bulkhead assembly 2 is provided with positioning pins at corresponding positions of the positioning holes 1121. By having the positioning pins pass through the positioning holes 1121, the assembly positioning of the instrument panel crossbeam assembly 1 and the front bulkhead assembly 2 can be achieved. However, as... Figure 2As shown, the virtual axis O formed by the mating position of the positioning pins at both ends and the positioning hole 1121 (i.e., the Z-direction support position) is misaligned with the center of gravity G of the instrument panel assembly in the length direction X of the vehicle. After the auxiliary tooling is removed, before it is tightened, the instrument panel assembly will flip around the aforementioned virtual axis O due to the unstable center of gravity, resulting in poor assembly stability of the instrument panel assembly.

[0051] This application provides an instrument panel assembly structure, which will be described in detail below with reference to the accompanying drawings.

[0052] like Figures 3 to 7 As shown, this application provides an instrument panel assembly structure for use in a vehicle. The instrument panel assembly structure includes a front bulkhead assembly 2 and an instrument panel crossbeam assembly 1 arranged sequentially along the length direction X of the vehicle. The instrument panel crossbeam assembly 1 includes an instrument crossbeam 11 and a front bulkhead bracket 12. The two ends of the instrument crossbeam 11 along the width direction Y of the vehicle are respectively connected to the front bulkhead assembly 2. The front bulkhead bracket 12 is connected to the instrument crossbeam 11 and extends at least partially toward the front bulkhead assembly 2. The front bulkhead assembly 2 is provided with a support member 23 at a corresponding position of the front bulkhead bracket 12, and the support member 23 is connected to the front bulkhead bracket 12.

[0053] In this embodiment, due to the presence of the support member 23, the connection between the front bulkhead bracket 12 and the support member 23, and the connection between the two ends of the instrument panel crossbeam 11 and the front bulkhead assembly 2, allows the front bulkhead assembly 2 to provide Z-axis support to the instrument panel crossbeam assembly 1 from three points, thereby forming a stable Z-axis support surface. This effectively prevents the instrument panel assembly from flipping during assembly and improves the assembly stability of the instrument panel assembly. It should be noted that the aforementioned Z-axis is also the vehicle's height direction Z.

[0054] In some optional embodiments of this application, such as Figure 3 As shown, the instrument crossbeam 11 includes: a crossbeam body 111 and two end plates 112; the crossbeam body 111 extends along the width direction Y of the vehicle; the two end plates 112 are disposed at both ends of the extension direction of the crossbeam body 111, and the two end plates 112 are respectively connected to the front bulkhead assembly 2. Further, the front bulkhead assembly 2 includes a front bulkhead 21 and two A-pillars 22, the front bulkhead 21 extends along the width direction Y of the vehicle, and the two A-pillars 22 are respectively disposed at both ends of the extension direction of the front bulkhead 21, wherein a support member 23 is disposed on the front bulkhead 21 and connected to the crossbeam body 111, and the end plates 112 are connected to the A-pillars 22.

[0055] In this embodiment, the end plate 112 allows for a reliable connection between the instrument panel beam assembly 1 and the front bulkhead assembly 2. Furthermore, the support member 23 on the front bulkhead 21 and the end plate 112 on the two A-pillars 22 form a triangular Z-axis support surface, effectively preventing the instrument panel assembly from flipping during assembly and further improving the assembly stability of the instrument panel assembly.

[0056] It should be noted that the connection methods between the support member 23 and the front bulkhead 21, and between the front bulkhead bracket 12 and the crossbeam body 111, are not limited in this application embodiment. Those skilled in the art can make adjustments according to actual needs. In one embodiment, the support member 23 and the front bulkhead 21 can be connected by spot welding, thereby strengthening the corresponding position of the front bulkhead 21 and better bearing the force on the instrument panel crossbeam assembly 1X (i.e., the length direction X of the vehicle). The front bulkhead bracket 12 and the crossbeam body 111 can be connected by carbon dioxide gas shielded arc welding, thereby providing a reliable mounting point for the steering column.

[0057] In some optional embodiments of this application, such as Figure 4 As shown, the end plate 112 is provided with either a positioning protrusion 221 or a positioning hole 1121, and the front assembly 2 is provided with the other positioning protrusion 221 or positioning hole 1121 at a position corresponding to the end plate 112. The positioning protrusion 221 passes through the positioning hole 1121. Specifically, the positioning protrusion 221 or the positioning hole 1121 is provided on the A-pillar 22.

[0058] In this embodiment, due to the provision of the positioning protrusion 221 and the positioning hole 1121, during the assembly of the instrument panel assembly, the cooperation between the positioning protrusion 221 and the positioning hole 1121 not only restricts the movement of the instrument panel assembly in the length and width directions of the vehicle, but also provides Z-axis support for the instrument panel assembly. Furthermore, the operator only needs to insert the positioning protrusion 221 into the positioning hole 1121 to complete the positioning assembly, which improves the ease of assembly of the instrument panel assembly.

[0059] It should be noted that the accompanying drawings of this application only show the case where a positioning hole 1121 is provided on the end plate 112 and a positioning protrusion 221 is provided at the corresponding position of the A-pillar 22. However, in actual applications, those skilled in the art can also provide a positioning protrusion 221 on the end plate 112 and a positioning hole 1121 at the corresponding position of the A-pillar 22, or provide both a positioning protrusion 221 and a positioning hole 1121 on the end plate 112 and both a positioning hole 1121 and a positioning protrusion 221 at the corresponding position of the A-pillar 22. No limitation is made here, and those skilled in the art can make adjustments according to actual needs.

[0060] In some optional embodiments of this application, at least a portion of the support member 23 protrudes toward the front bulkhead bracket 12 to form a boss 231; the front bulkhead bracket 12 overlaps the boss 231. In one embodiment, the support member 23 is a sheet metal part, and the boss 231 may be formed by stamping the sheet metal part.

[0061] In the embodiments of this application, such as Figure 7 As shown, due to the presence of the boss 231, during the assembly of the instrument panel assembly—that is, as the auxiliary tooling pushes the instrument panel assembly toward the front bulkhead assembly 2—the front bulkhead bracket 12 can continuously move closer to the boss 231 and overlap above it. This simplifies the assembly process while providing reliable support for the front bulkhead bracket 12, thereby reducing the assembly difficulty and improving the assembly efficiency of the instrument panel assembly.

[0062] In some optional embodiments of this application, such as Figures 5 to 7 As shown, the front bulkhead bracket 12 includes: a connector 121 and an overlap member 122; the connector 121 is connected to the instrument crossbeam 11; the overlap member 122 is disposed at the end of the connector 121 away from the instrument crossbeam 11, and the overlap member 122 overlaps the boss 231.

[0063] In this embodiment, due to the provision of the overlapping member 122, a stable force transmission path can be formed between the instrument panel beam assembly 1 and the front bulkhead assembly 2 through the connection between the overlapping member 122 and the connecting member 121, and the overlapping of the overlapping member 122 and the boss 231. That is, part of the weight of the instrument panel assembly can be transmitted to the overlapping member 122 through the connecting member 121, and then from the overlapping member 122 to the boss 231 for dispersion, thereby ensuring the reliability of the instrument panel assembly's support. In addition, compared to the connecting member 121 directly overlapping the boss 231, the provision of a dedicated overlapping member 122 can better adapt to the connecting member 121 and the boss 231, thereby improving the ease of assembly and assembly stability of the front bulkhead bracket 12 and the boss 231.

[0064] It should be noted that the overlapping member 122 in this embodiment of the application may be provided as a single piece or as multiple pieces, and no limitation is made herein. Those skilled in the art can adjust it according to actual needs. When multiple overlapping members 122 are provided, the multiple overlapping members 122 can be distributed at intervals in the width direction Y of the vehicle, thereby further dispersing the force and effectively avoiding stress concentration.

[0065] Further, the connector 121 includes a first connector 1211 and a second connector 1212. The first connector 1211 extends along the length direction X of the vehicle, and its two ends are connected to the instrument crossbeam 11 and the second connector 1212, respectively. The second connector 1212 is connected to the support member 23 and the front bulkhead 21. The overlapping member 122 can be disposed on either the first connector 1211 or the second connector 1212; this is not limited, and those skilled in the art can adjust it according to actual needs. It should be noted that the connection method of the first connector 1211 and the second connector 1212 is not limited in this embodiment; those skilled in the art can adjust it according to actual needs. In one embodiment, the first connector 1211 and the second connector 1212 can be connected by welding, specifically by carbon dioxide gas shielded arc welding, thereby achieving a reliable connection between the first connector 1211 and the second connector 1212.

[0066] In some optional embodiments of this application, such as Figure 7 As shown, the boss 231 has a first overlapping surface 2311, which extends along a first direction M, and the first direction M is set at an angle to the length direction X of the vehicle; the connecting member 122 has a second overlapping surface 12211, which is parallel to the first overlapping surface 2311 and abuts against each other.

[0067] In this embodiment, the first lap surface 2311 is inclined relative to the horizontal plane because its extension direction (i.e., the first direction M) forms an angle with the vehicle's length direction X. This has two advantages: firstly, for the stamped boss 231, the inclined first lap surface 2311 reduces the processing difficulty of the boss 231; secondly, the inclined first lap surface 2311 acts as a guide during assembly, allowing operators to easily guide the lap member 122 to the accurate position along the inclined direction, thereby improving the assembly accuracy of the instrument panel assembly and reducing its assembly difficulty. By having the first lap surface 2311 and the second lap surface 12211 parallel and abutting against each other, the contact area between the boss 231 and the lap member 122 is increased, resulting in a more even distribution of force and further improving the assembly stability of the instrument panel assembly.

[0068] It should be noted that the embodiments of this application do not limit the angle between the first direction M and the vehicle length direction, and those skilled in the art can adjust it according to actual needs. In some optional embodiments of this application, the angle between the first direction M (i.e., the extension direction of the first overlapping surface 2311) and the vehicle length direction X is 25° to 35°.

[0069] Generally speaking, the larger the angle between the first direction M and the vehicle's length direction X, i.e., the larger the tilt angle of the boss 231, the worse the Z-direction support effect of the boss 231 on the front bulkhead bracket 12. Conversely, the smaller the angle between the first direction M and the vehicle's length direction X, i.e., the smaller the tilt angle of the boss 231, the greater the processing difficulty of the boss 231 and the worse its guiding effect on the overlapping part 122. Tests have shown that when the angle between the first direction M and the vehicle's length direction X is between 25° and 35°, the boss 231 can achieve both good support and guiding effects, while simultaneously reducing the processing difficulty of the boss 231.

[0070] It should be noted that the specific value of the angle between the first direction M and the length direction X of the vehicle is not limited in the embodiments of this application, and those skilled in the art can adjust it according to actual needs. For example, the angle between the first direction M and the length direction X of the vehicle can be 25°, 27°, 30°, 32°, 35° or other values.

[0071] In some optional embodiments of this application, such as Figures 8 to 9 As shown, the connecting member 122 includes an overlapping portion 1221 and an arc-shaped guide portion 1222. The overlapping portion 1221 is connected to the connecting member 121 and overlaps with the boss 231. The arc-shaped guide portion 1222 is disposed at one end of the overlapping portion 1221 away from the instrument crossbeam 11, and the arc-shaped guide portion 1222 is used to guide the overlapping portion 1221 to engage with the boss 231. Specifically, the cross-sectional shape of the overlapping portion 1221 in the direction perpendicular to the length of the vehicle can be U-shaped. The open end of the U-shaped overlapping portion 1221 is connected to the connecting member 121, and the second overlapping surface 12211 is formed at the other end that is opposite to the open end.

[0072] Generally, when the dashboard crossbeam assembly 1 is assembled to the front bulkhead assembly 2 along the length X of the vehicle, the fitting process of the boss 231 and the connecting piece 122 is not visible due to the obstruction of the dashboard and other components. Based on this, in this embodiment, since an arc-shaped guide portion 1222 is provided, when there is a Z-direction (i.e., the height Z direction of the vehicle) misalignment between the front bulkhead bracket 12 and the boss 231, the contact between the arc-shaped surface of the arc-shaped guide portion 1222 and the boss 231 can guide and correct the fitting of the connecting piece 122 during assembly, thereby improving the assembly accuracy and efficiency of the front bulkhead bracket 12 and the boss 231.

[0073] In some optional embodiments of this application, the overlapping member 122 further includes a flange 1223, which is disposed on the side of the overlapping member 1221 near the connector 121, and is connected to the connector 121. Further, the flange 1223 is disposed at the open end of the U-shaped overlapping member 1221; specifically, the flange 1223 may be formed by at least a portion of the open end of the U-shaped overlapping member 1221 extending in a direction away from its center.

[0074] In this embodiment, since a flange 1223 is provided, and the flange 1223 is connected to the connector 121, the connection area between the overlapping member 122 and the connector 121 can be increased, thereby improving the connection reliability between the overlapping member 122 and the connector 121, which is conducive to further improving the assembly stability of the instrument panel assembly.

[0075] It should be noted that the connection method between the flange 1223 and the connector 121 is not limited in the embodiments of this application, and those skilled in the art can make adjustments according to actual needs. In one embodiment, the flange 1223 and the connector 121 can be connected by welding. Specifically, carbon dioxide gas shielded arc welding can be used for welding, thereby improving the welding accuracy and stability of the flange 1223 and the connector 121 and achieving a reliable connection between the two.

[0076] In some optional embodiments of this application, such as Figure 7 As shown, the front bulkhead bracket 12 also includes a fastener 123 and an adjusting nut 124. The fastener 123 is sequentially inserted through the front bulkhead 21 and the support member 23 and connected to the second connecting member 1212. The adjusting nut 124 is sleeved on the fastener 123 and located between the support member 23 and the second connecting member 1212, thereby absorbing the assembly tolerance between the front bulkhead 21 and the front bulkhead bracket 12. The adjusting nut 124 is an existing product, and the specific structure and working principle of the adjusting nut 124 will not be described in detail in this embodiment.

[0077] Furthermore, at least a portion of the arc-shaped guide portion 1222 of the overlapping portion 1221 can protrude beyond the second connector 1212, thereby providing a pre-guiding function before the front bulkhead bracket 12 and the boss 231 are assembled, facilitating the subsequent smooth assembly of the front bulkhead bracket 12 and the boss 231. It is understood that the dimension by which the arc-shaped guide portion 1222 protrudes beyond the second connector 1212 in the assembly direction should be smaller than the dimension of the adjusting nut 124 in the assembly direction, to prevent the arc-shaped guide portion 1222 from contacting the support member 23 first during assembly, thus avoiding the risk of assembly failure.

[0078] In summary, the instrument panel assembly structure provided in this application embodiment has at least the following advantages:

[0079] In this embodiment, due to the provision of a support member, the connection between the front bulkhead bracket and the support member, and the connection between the two ends of the instrument crossbeam and the front bulkhead assembly, the front bulkhead assembly can provide Z-axis support to the instrument crossbeam assembly from three points, thereby forming a stable Z-axis support surface. This effectively avoids the problem of the instrument panel assembly flipping during assembly and helps to improve the assembly stability of the instrument panel assembly.

[0080] This application also provides a vehicle including the dashboard assembly structure of any of the above embodiments.

[0081] In this embodiment, by providing an instrument panel assembly structure that prevents tipping, the assembly stability of the instrument panel assembly can be improved, ensuring reliable assembly of the instrument panel assembly with other vehicle components (such as auxiliary instruments, door trim panels, etc.), which is beneficial for improving vehicle production efficiency and product quality. It should be noted that in this embodiment, the structure of the instrument panel assembly structure is the same as that of any of the instrument panel assembly structures described above, and its beneficial effects are similar, so further details will not be elaborated here. In this application, "multiple" refers to two or more.

[0082] In this application, unless otherwise expressly defined, the terms "installation," "connection," and "linking" 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; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0083] The terms “first,” “second,” “third,” “fourth,” etc., in this application (if present) are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0084] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0085] Unless otherwise specified, all steps in this application may be performed sequentially or randomly. For example, if the method includes steps A and B, it means that the method may include steps A and B performed sequentially, or it may include steps B and A performed sequentially.
