[0100] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0101] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may also be an element centered therein. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may also be an element centered therein. When an element is considered to be "set on" another element, it may be directly set on the other element or there may also be an element centered therein. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0102] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "or / and" as used herein includes any and all combinations of one or more of the relevant listed items.

[0103] Some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features of the embodiments can be combined with each other.

[0104] Some known guide rail assemblies include a triangle plate outer plate, a triangle plate inner plate, a guide rail and a lower bracket. The four are formed by stamping metal sheets and connected by welding to form an integral guide rail assembly, which has a high processing cost. During the welding process of the four parts, the tolerances generated between the parts accumulate, making it more difficult to control the precision of the guide rail assembly. At the same time, the welding process requires notches to be set at the triangle plate inner plate and the triangle plate outer plate, which will result in poor stiffness at the triangle plate inner plate and the triangle plate outer plate, and there is a risk of air leakage, affecting the sealing performance of the vehicle. In addition, the known guide rail assemblies also have the problem of being heavy, which is not conducive to lightweighting.

[0105] See also Figure 1 and Figure 2This embodiment provides a vehicle 200 including a vehicle body 201 and a door assembly 100. The door assembly 100 may be a front door assembly 100 or a rear door assembly 100. The door assembly 100 is mounted on the vehicle body 201.

[0106] The vehicle door assembly 100 includes a vehicle door body 20, a vehicle window glass 30, and a vehicle window guide track structure 10. The vehicle window guide track structure 10 is connected to the vehicle door body 20, and the vehicle window glass 30 is slidably engaged with the vehicle window guide track structure 10. The vehicle window guide track structure 10 is used to guide the lifting direction of the vehicle window glass 30.

[0107] See also Figures 3 to 6 The window guide rail structure 10 includes an integrally formed mounting portion 11 and a guide rail 12. The mounting portion 11 is configured to be mounted on a corner window 202 (see FIG. Figure 1 ), one end of the guide rail 12 is integrally connected to the mounting portion 11, the guide rail 12 extends toward the bottom of the vehicle 200, and the end of the guide rail 12 away from the mounting portion 11 is configured to be connected to the door body 20 of the vehicle 200.

[0108] According to the window rail structure 10 of this embodiment, the mounting portion 11 and guide rail 12 are integrally molded. Compared to conventional welding processes, this reduces the cumulative error during the welding process, thereby improving the dimensional accuracy of various parts of the window rail structure 10 and facilitating improved vehicle assembly accuracy. Furthermore, the mounting portion 11 and guide rail 12 do not require grooves or notches, thereby ensuring a better seal between the mounting portion 11 and other parts of the vehicle 200 and ensuring a reliable seal. Furthermore, the integral molding process reduces the component complexity and cost of the window rail structure 10 and increases the rigidity of the connection between the mounting portion 11 and guide rail 12, further enhancing the overall rigidity of the mounting portion 11 and improving the reliability of the window rail structure 10.

[0109] In some embodiments, the mounting portion 11 and the guide rail 12 are integrally formed by injection molding, thereby reducing the weight of the window guide rail structure 10 and facilitating lightweighting.

[0110] Specifically, the mounting portion 11 and guide rail 12 can be injection molded from a composite plastic material. The composite plastic material can be a thermoplastic such as Bulk Molding Compound (BMC). For example, the composite plastic material can include plastic, inert fillers, fiber reinforcements, catalysts, stabilizers, and pigments. Parts made from this composite plastic material exhibit high mechanical properties, corrosion resistance, heat resistance, and aging resistance, as well as high dimensional stability, thereby extending the service life of the window rail structure 10 and ensuring its effective guidance of the window glass 30. The fiber reinforcement can be a reinforcing material such as carbon fiber or glass fiber.

[0111] In addition, compared with the existing triangular plate structure installed on the corner window, the mounting portion 11 of this embodiment does not need to be constructed by welding or bending two sheet metal parts, so that a structure of the mounting portion 11 with a certain thickness can be provided. While ensuring the strength of the mounting portion 11, the weight of the mounting portion 11 is further reduced.

[0112] In some embodiments, see Figure 4 The mounting portion 11 includes a first side S1, a second side S2, and a third side S3. The thickness of the first and second sides S1, S2 is greater than that of the third side S3. The thickness of the mounting portion 11 gradually decreases as it approaches the third side S3. This facilitates the provision of openings or connecting structures within the mounting portion 11, thereby improving the reliability of the connection between the mounting portion 11 and other components of the vehicle 200. Furthermore, the gradually decreasing thickness of the third side S3 facilitates assembly of the mounting portion 11 on the corner window 202.

[0113] In some embodiments, see Figure 7 and Figure 8 The window track structure 10 further includes a first fixing portion 141. The first fixing portion 141 is embedded in an edge of the mounting portion 11 near the second side S2 and is configured to connect to the door body 20. The first fixing portion 141 can be molded into the mounting portion 11 during the injection molding process, thereby improving the convenience and reliability of the connection between the mounting portion 11 and the door body 20.

[0114] In some embodiments, the first fixing portion 141 can be configured as a pre-embedded nut embedded in the mounting portion 11 to facilitate connection to the door body 20 via a fastening structure. Specifically, the end face of the pre-embedded nut and the surface of the mounting portion 11 are coplanar. This ensures that, after the mounting portion 11 and the door body 20 are connected, the inter-surface clearance between the mounting portion 11 and the door body 20 meets the required requirements, thereby improving installation accuracy.

[0115] The number of the first fixing portions 141 can be two or more. In this embodiment, the number of the first fixing portions 141 is two, and the two first fixing portions 141 are spaced apart along the length direction of the second side S2.

[0116] In some embodiments, see Figures 9 to 11The guide rail 12 includes an integrally formed bottom wall 121, a first side wall 122, and a second side wall 123. The bottom wall 121 is connected to the mounting portion 11. The first side wall 122 is integrally formed on one side of the bottom wall 121 and extends in a direction away from the mounting portion 11. The second side wall 123 is integrally formed on the other side of the bottom wall 121 and extends in a direction away from the mounting portion 11. The bottom wall 121, the first side wall 122, and the second side wall 123 together form a second guide groove C2. Among them, one end of the first side wall 122, a portion of the second side wall 123, and the first side S1 of the mounting portion 11 together form a first guide groove C1. In this way, the openings of the first guide groove C1 and the second guide groove C2 are both away from the mounting portion 11, which is convenient for guiding the vehicle window glass 30 to rise and fall.

[0117] In some embodiments, a first protrusion 124 is provided on a side of the first side wall 122 facing the second side wall 123, and a second protrusion 125 is provided on a side of the second side wall 123 facing the first side wall 122. The first protrusion 124 and the second protrusion 125 can clamp the sealing strip structure within the first guide groove C1 and the second guide groove C2, thereby improving the installation stability of the sealing strip structure within the first guide groove C1 and the second guide groove C2.

[0118] In some embodiments, the thickness of the bottom wall 121, the first side wall 122 and the second side wall 123 are approximately the same and are all between 1 mm and 2 mm. For example, the thickness of the three can be set to 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm or 2 mm to ensure the overall strength of the guide rail 12.

[0119] In some embodiments, see Figure 9 and Figure 12 The window guide rail structure 10 further includes a connecting portion 13, which is integrally connected to an end of the guide rail 12 away from the mounting portion 11. The connecting portion 13 is configured to be connected to the door body 20. In this way, the machining accuracy error of the window guide rail structure 10 can be further reduced, and the machining cost can be reduced.

[0120] In some embodiments, the connecting portion 13 is integrally formed with the guide rail 12 and the mounting portion 11 through an injection molding process, which can further reduce the weight of the window guide rail structure 10 and further achieve the goal of lightweighting.

[0121] In other embodiments, the guide rail 12 may also be connected to the door body 20 via other detachable connection structures.

[0122] In some embodiments, see Figure 12The window rail structure 10 further includes a fastening portion 142 disposed on the connecting portion 13 and configured to connect to the door body 20. The fastening portion 142 can be molded inside the connecting portion 13 during the injection molding process, thereby improving the convenience and reliability of connecting the connecting portion 13 to the door body 20.

[0123] The fastening portion 142 can be configured as an embedded nut to facilitate connection with the door body 20 via a fastening structure such as a screw. In other embodiments, the fastening portion 142 can also be configured as an embedded screw that passes through the door body 20 and is connected to a fastening structure such as a nut.

[0124] In some embodiments, see Figure 12 , along the width direction of the guide rail 12 , the connecting portion 13 extends in a direction away from the mounting portion 11 .

[0125] In some embodiments, the connecting portion 13 includes a first plate segment 131 and a second plate segment 132. The first plate segment 131 is connected to the junction of the second side wall 123 and the bottom wall 121 of the guide rail 12 and is tilted toward the door body 20, away from the mounting portion 11. The second plate segment 132 is connected to the end of the first plate segment 131 facing away from the guide rail 12 and is substantially attached to the door body 20. The fastening portion 142 is integrally formed with the second plate segment 132 and is connected to the door body 20 via a fastening structure. In this manner, the connection between the connecting portion 13 and the door body 20 is achieved while maintaining a certain distance between the guide rail 12 and the door body 20.

[0126] In this embodiment, a plurality of connecting portions 13 may be provided, and the plurality of connecting portions 13 are spaced apart along the length direction of the guide rail 12 to further improve the connection reliability between the window guide rail structure 10 and the door body 20 .

[0127] In some embodiments, see Figure 13 The door assembly 100 further includes a sealing assembly 40. The sealing assembly 40 includes a sealing portion 41 and a first sealing strip 42. The sealing portion 41 is configured to be connected to the door body 20 and to the mounting portion 11. The first sealing strip 42 is connected to the sealing portion 41. The first sealing strip 42 is mounted on the guide rail 12 of the window guide rail structure 10 and is configured to be clamped between the guide rail 12 and the window glass 30. The first sealing strip 42 is integrally formed with the sealing portion 41.

[0128] In some embodiments, see Figures 13 to 15The sealing portion 41 defines a mounting cavity Q having a first cavity wall P1 and a second cavity wall P2 disposed opposite each other. A first reinforcement portion 411 is protruding from the first cavity wall P1, and a second reinforcement portion 412 is protruding from the second cavity wall P2. The mounting portion 11 of the window rail structure 10 is clamped between the first reinforcement portion 411 and the second reinforcement portion 412. This improves the connection reliability between the sealing portion 41 and the mounting portion 11.

[0129] In some embodiments, the first reinforcement portion 411 includes a plurality of reinforcement ribs disposed at intervals. The second reinforcement portion 412 includes a plurality of reinforcement ribs disposed at intervals.

[0130] In some embodiments, see Figure 15 and Figure 16 The first sealing strip 42 includes a first wall section 421, a second wall section 422, and a third wall section 423. The second wall section 422 and the third wall section 423 are respectively connected to two sides of the first wall section 421. The first wall section 421, the second wall section 422, and the third wall section 423 together form a sealing groove C3, into which the door glass extends.

[0131] In some embodiments, a first sealing lip 44 is provided on the surface of the first wall segment 421 and / or the third wall segment 423 to improve the sealing performance to the vehicle door glass.

[0132] In some embodiments, the end of the second wall segment 422 facing away from the first wall segment 421 is integrally formed with the sealing portion 41, and the end of the third wall segment 423 facing away from the first wall segment 421 is integrally formed with the sealing portion 41. The sealing portion 41 also has a second sealing lip 413 and a third sealing lip 414 extending into the sealing groove C3. The second sealing lip 413 is connected to the second wall segment 422, and the third sealing lip 414 is connected to the third wall segment 423. This further improves the sealing performance of the vehicle door glass.

[0133] In some embodiments, see Figure 13 The sealing assembly 40 further includes a second sealing strip 43 (also visible in Figure 3 and Figure 4 The second sealing strip 43 extends substantially along the length of the vehicle 200 and is mounted on the inner side of the sheet metal of the vehicle body 201 , serving as an inner watertight seal for the door assembly 100 . The second sealing strip 43 is integrally formed with the sealing portion 41 .

[0134] In some embodiments, see Figure 17 and Figure 18The door assembly 100 further includes an A-pillar trim 50. The A-pillar trim 50 is located on the side of the sealing portion 41 facing the outside of the vehicle 200 to provide decorative protection. The A-pillar trim 50 is connected to the mounting portion 11. In some embodiments, the A-pillar trim 50 is located on the side of the mounting portion 11 facing away from the first fixing portion 141.

[0135] In some embodiments, see Figures 17 to 19 The mounting portion 11 also includes an integrally formed snap-fitting portion 151, which is protruding from the connection between the first side S1 and the third side S3. The mounting portion 11 also has a first snap-fitting hole K1, which is located at the connection between the third side S3 and the second side S2. The mounting portion 11 also has a fixing hole K2. The fixing hole K2 is located at the connection between the second side S2 and the first side S1. The A-pillar decorative component 50 also includes a first snap-fitting portion 54, a second snap-fitting portion 55, and a second fixing portion 56. The first snap-fitting portion 54 is snap-fitted into the first snap-fitting hole K1, and the second snap-fitting portion 55 has a second snap-fitting hole K3, and the snap-fitting portion 151 is snap-fitted into the second snap-fitting hole K3. The second fixing portion 56 corresponds to the fixing hole K2 and is fixedly connected to the mounting portion 11 through a fastening structure.

[0136] This creates a triangular fixed connection between the mounting portion 11 and the A-pillar trim 50, thereby enhancing the connection stability between the A-pillar trim 50 and the mounting portion 11. During assembly, the first engaging hole K1 is first engaged with the first engaging portion 54, the second engaging hole K3 is engaged with the engaging portion 151, and then the second fixing portion 56 is connected to the fixing hole K2 via the fastening structure.

[0137] In other embodiments, the position of the mounting portion 11 corresponding to the fixing hole K2 may not be opened, but an embedded nut may be provided at the position corresponding to the fixing hole K2 and connected to the second fixing portion 56 through the embedded nut.

[0138] In some embodiments, see Figure 14 A first through hole K5, a second through hole K6, and a third through hole K7 are formed on the side wall of the sealing portion 41 near the A-pillar trim 50. The first through hole K5, the second through hole K6, and the third through hole K7 all communicate with the mounting cavity Q. The first through hole K5 corresponds to the first engaging hole K1, the second through hole K6 corresponds to the engaging portion 151, and the third through hole K7 corresponds to the fixing hole K2. In this way, the A-pillar trim 50 is connected to the mounting portion 11 within the mounting cavity Q.

[0139] In some embodiments, see Figure 17 and Figure 18The hole surface of the first clamping hole K1 is protrudingly provided with a clamping portion 152, and the clamping portion 152 defines a through hole K4. The first clamping portion 54 includes a clamping section 541 and a limiting section 542. The clamping section 541 is accommodated in the through hole K4, and the limiting section 542 is connected to the clamping section 541. The projected area of ​​the limiting section 542 on the clamping portion 152 is larger than the cross-sectional area of ​​the clamping section 541, thereby limiting the first clamping portion 54 from being separated from the first clamping hole K1, thereby improving the clamping reliability of the first clamping hole K1 and the first clamping portion 54.

[0140] In some embodiments, the penetration direction of the second clamping hole K3 is substantially parallel to the plate surface of the mounting portion 11 .

[0141] When assembling the door assembly 100 of this embodiment, the mounting portion 11 of the window guide rail structure 10 is first installed in the mounting cavity Q of the sealing portion 41, and then the A-pillar decorative component 50 is arranged on the outer side surface of the sealing portion 41, and the A-pillar decorative component 50 is snap-connected and fixed to the mounting portion 11.

[0142] The above embodiments are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent replacements of the technical solutions of the present application should not depart from the spirit and scope of the technical solutions of the present application.
