Description

Technical Field

[0001] This application relates to the field of automotive door glass guide rail assembly technology, and in particular to guide rail assemblies, automotive door glass assemblies, and vehicles. Background Technology

[0002] As consumers' standards for vehicle appearance continue to rise, many manufacturers have begun exploring designs such as narrow-bezel doors and frameless doors. The production of narrow-bezel or frameless doors requires sacrificing the wall width of the guide rail assembly that accompanies the door glass to achieve the desired narrow bezel or even frameless appearance. However, in the manufacturing process of the door glass guide rail assembly, most of them adopt an integrated design, and guide rail assemblies with narrow or even no wall widths are difficult to support long-distance lifting and lowering movements of the door glass.

[0003] In related technologies, manufacturers use milling and other cutting operations to narrow the wall width of the guide rail assembly corresponding to the upper part of the door glass after it has been integrally molded. The different guide rail wall widths formed after milling and other cutting operations allow the guide rail assembly to have multiple guide rail segments, which can meet various production requirements of vehicles.

[0004] However, milling and other cutting operations on the integrated guide rail assembly will have the following defects: First, the cutting equipment is prone to positional interference with the guide rail assembly. Second, due to the limited design space inside the car door, coupled with the limitations of the wiring harness and other parts of the electrical components inside the car door, there is often a certain deviation from the preset cutting position, resulting in poor processing accuracy of the guide rail assembly.

[0005] Secondly, significant processing errors negatively impact subsequent yield rates. During milling and other cutting operations on guide rail components, processing errors are unavoidable, such as milling cutter vibration, differences in machining accuracy between different milling cutters, inaccurate tooling positioning, and internal stress generated during processing. Taking the generation of internal stress during milling and other cutting operations as an example, in subsequent post-processing (such as electrophoresis and painting on car doors), significant temperature changes can lead to stress release, potentially causing secondary deformation of the guide rail or design deviations. Summary of the Invention

[0052] 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.

[0053] According to the first aspect of this application, Figure 1 As shown, this application provides a door glass assembly 10, including a guide rail assembly 100 and a movable window glass.

[0054] like Figure 2 As shown, the guide rail assembly 100 includes a first guide rail 110 and a second guide rail 120. The first guide rail 110 extends along its length direction X and is provided with a first groove 110a. The second guide rail 120 extends along its length direction X and is provided with a second groove 120a. The first guide rail 110 and the second guide rail 120 are mated together along the length direction X so that the first groove 110a and the second groove 120a communicate. The movable window glass can be slidably disposed in the first groove 110a and the second groove 120a.

[0055] Along the length direction X of the first slide groove 110a, the cross-sectional shape of the first slide groove 110a in the length direction X is different from that of the second slide groove 120a in the length direction X, and the first guide rail 110 and the second guide rail 120 are arranged in a separate structure. The difference in cross-sectional shape can refer to the difference in cross-sectional area or the difference in cross-sectional graphic structure, etc.

[0056] It is understandable that in the manufacturing of products such as frameless car doors, the actual cross-sectional shapes of the first guide rail 110 and the second guide rail 120 will be different. Unlike related technologies, which integrally form the guide rail assembly 100 and then cut it to form guide rails of different shapes, this application uses separate processing of the first guide rail 110 and the second guide rail 120, which reduces the difficulty of cutting the guide rail assembly 100 after integral forming and is conducive to improving the processing efficiency of the guide rail assembly 100.

[0057] Furthermore, the first guide rail 110 and the second guide rail 120 are set in a split structure, which allows the first guide rail 110 and the second guide rail 120 to be set differently, so as to make adaptive adjustments according to different production scenarios and enrich the application scenarios of the guide rail assembly 100.

[0058] In one example, the movable window glass can be driven by a drive component connected to the movable window glass to slide in the first groove 110a and the second groove 120a.

[0059] According to a second aspect of this application, this application also provides a vehicle, including a door glass assembly 10, a vehicle body, and a door assembly. The door assembly is disposed on the vehicle body, and the door glass assembly 10 is mounted on the door assembly. Thus, by mounting the door glass assembly 10 on the door assembly, the door assembly can meet diverse processing requirements, such as being processed into narrow-frame doors or frameless doors, improving the vehicle's appearance. Furthermore, by reducing the processing difficulty of the door glass assembly 10, it is beneficial to improve the vehicle's processing efficiency and yield rate.

[0060] Accordingly, in some embodiments, combined with Figure 3 , Figure 4 as well as Figure 5 As shown, the door glass assembly 10 also includes a corner window glass 200. The corner window glass 200 is spaced apart from the operable window glass. A guide rail assembly 100 is installed on the corner window glass 200 and positioned between the corner window glass 200 and the operable window glass. That is, the guide rail assembly 100 of this application can also be used to connect the corner window glass 200, improving the integration performance of the door glass assembly and reducing space occupation.

[0061] In one embodiment, such as Figure 3 as well as Figure 4As shown, the first guide rail 110 has a first mounting groove 110b on the side opposite to the movable window glass. The first mounting groove 110b is used to insert and cooperate with the corner window glass 200. In this way, the insertion and cooperation between the first mounting groove 110b and the corner window glass 200 helps to improve the connection stability of the corner window glass 200 on the guide rail assembly 100.

[0062] In another embodiment, such as Figure 5 As shown, the second guide rail 120 has a second mounting groove 120b on the side opposite to the movable window glass. The second mounting groove 120b is used to insert and cooperate with the corner window glass 200. Similarly, the insertion and cooperation between the second mounting groove 120b and the corner window glass 200 helps to improve the connection stability of the corner window glass 200 on the guide rail assembly 100.

[0063] In some implementations, see back Figure 3 as well as Figure 4 The first groove 110a has a first sidewall portion 111 and a second sidewall portion 112 opposite each other along its width direction Y. The height of the first sidewall portion 111 in the depth direction Z of the first groove 110a is less than the height of the second sidewall portion 112 in the depth direction Z.

[0064] Understandably, the first guide rail 110 can be designed in the upper part of the door glass assembly 10, corresponding to the window portion of the vehicle door assembly. Correspondingly, the second guide rail 120 can be designed in the lower part of the door glass assembly 10, corresponding to the area of ​​the door assembly opposite to the window portion. Because the height of the first sidewall portion 111 in the depth direction Z is less than that of the second sidewall portion 112, the first sidewall portion 111 can achieve a narrow bezel or even a frameless effect compared to the second sidewall portion 112 (at which point the height of the first sidewall portion 111 can approach 0). This satisfies the requirement of a narrow bezel or frameless design in narrow-bezel or frameless doors. Furthermore, the larger height of the second sidewall portion 112 provides sufficient support area for the movable window glass, ensuring the supporting performance of the first guide rail 110 on the movable window glass and guaranteeing the stability of the movable window glass when moving on the first guide rail 110.

[0065] Furthermore, in one embodiment, see back Figure 5 The second slide groove 120a is provided with a third side wall portion 121 and a fourth side wall portion 122 opposite to each other along its width direction Y. The third side wall portion 121 is mated with the first side wall portion 111, and the fourth side wall portion 122 is mated with each other. The height of the third side wall portion 121 and the fourth side wall portion 122 in the depth direction Z is greater than the height of the first side wall portion 111 in the depth direction Z.

[0066] Thus, by ensuring that the heights of the third sidewall portion 121 and the fourth sidewall portion 122 are both greater than the height of the first sidewall portion 111, the contact area between the second guide rail 120 and the movable window glass during sliding is increased, thereby improving the movement stability of the movable window glass on the second guide rail 120 and achieving stable movement of the movable window glass. Furthermore, when configured with the first guide rail 110, the design balances the aesthetic performance of a narrow frame or frameless design while maintaining the supporting strength of the guide rail assembly 100, thus improving the sliding stability of the movable window glass during sliding of the guide rail assembly 100.

[0067] Alternatively, in one embodiment, see back Figure 5 The height of the third side wall portion 121 in the depth direction Z is equal to the height of the fourth side wall portion 122 in the depth direction Z. Thus, when both the third side wall portion 121 and the fourth side wall portion 122 are in contact with the movable window glass, their equal height provides similar or even equal contact areas on both sides of the movable window glass in the width direction Y, thereby ensuring uniform stress on the movable window glass and guaranteeing its movement stability.

[0068] Furthermore, the thickness of the third sidewall portion 121 in the width direction Y is equal to the thickness of the fourth sidewall portion 122 in the width direction Y. This equal thickness of the third and fourth sidewall portions 121 in the width direction Y ensures consistent structural strength between them, thereby guaranteeing that the movable window glass experiences uniform force when it comes into contact with the third and fourth sidewall portions 121 and 122 in the width direction Y. This reduces the swaying of the movable window glass and improves its movement stability.

[0069] It should be noted that the cross-sectional shapes of the first guide rail 110 and the second guide rail 120 in the above embodiments can be various, such as C-shaped, L-shaped, U-shaped, etc., and no further restrictions are imposed here.

[0070] In one embodiment, see Figures 3 to 5 As shown, the cross-sectional area of ​​the first slide rail 110a in the length direction X is smaller than that of the second slide rail 120a in the length direction X. Thus, the smaller cross-sectional area of ​​the first guide rail 110 ensures that when the movable window glass is engaged with the first guide rail 110, the first guide rail 110 does not significantly affect the appearance of the movable window glass, improving the overall appearance of the door glass assembly 10. Simultaneously, the larger cross-sectional area of ​​the second guide rail 120 provides a larger support area for the movable window glass in the width direction Y, thereby improving the stability of the movable window glass's movement on the second guide rail 120.

[0071] In one example, such as Figure 3As shown, the cross-section of the first slide groove 110a along the length direction X is L-shaped. This L-shaped structure ensures that the first slide groove 110a covers the area of ​​the movable window glass while allowing for the absence of the first sidewall portion 111 in the above embodiment, thus achieving the aesthetic performance of a frameless door.

[0072] In another example, such as Figure 5 As shown, the second slide rail 120a has a U-shaped cross-section in the length direction X. This U-shaped slide rail design allows the second slide rail 120a to effectively cover the movable window glass, ensuring the sliding stability of the movable window glass during sliding contact with the second slide rail 120a and reducing the risk of derailment.

[0073] Accordingly, see you Figure 1 In conjunction with any embodiment of the first sidewall portion 111 and the second sidewall portion 112 described above, the door assembly has a first side and a second side opposite to each other along the height direction of the vehicle body. The door assembly has a perforated portion and a non-perforated portion, which are arranged adjacent to each other. The perforated portion is connected to the first side of the door assembly. The non-perforated portion is connected to the second side of the door assembly. The perforated portion is used for mounting and cooperating with the movable window glass. The first guide rail 110 is correspondingly arranged with the perforated portion. The second guide rail 120 is correspondingly arranged with the non-perforated portion. In one example, the height direction and the length direction X are aligned in the same direction.

[0074] Thus, the first guide rail 110 corresponds to the hollow part of the door assembly. In terms of appearance, the first guide rail 110 is within the observable line of sight. The size difference between the first side wall 111 and the second side wall 112 makes the first side wall 111 present a narrow frame or even a frameless effect within the line of sight, thus achieving the appearance performance of a narrow frame door or even a frameless door.

[0075] It should be noted that the connection between the first guide rail 110 and the second guide rail 120 can be a non-removable connection such as bonding or welding, or a detachable connection such as riveting or screwing. No further restrictions are imposed here.

[0076] In some embodiments, combined with Figure 2 as well as Figure 6 As shown, the guide rail assembly 100 also includes a connector 130. The connector 130 includes a connecting body 131. The first guide rail 110 and the second guide rail 120 are spaced apart along the length direction X. The connecting body 131 is connected between the first guide rail 110 and the second guide rail 120.

[0077] Thus, by connecting the connecting body 131 between the first guide rail 110 and the second guide rail 120, the connecting body 131 can serve as a connecting transition part when the first guide rail 110 and the second guide rail 120 are mated together. This reduces the alignment difficulty when the first guide rail 110 and the second guide rail 120 are directly connected, thereby improving the alignment accuracy when the first guide rail 110 and the second guide rail 120 are directly connected. This ensures that the first slide groove 110a, the clearance part 130a and the second slide groove 120a are accurately aligned, making the movement of the movable window glass smoother.

[0078] It should be noted that the connecting body 131 can be connected to the outer wall of the first guide rail 110 and the second guide rail 120, or to the groove wall of the first slide groove 110a and the second slide groove 120a, etc. Different connection positions can be selected according to different production needs, and no further restrictions are made here.

[0079] Optionally, in one embodiment, the connection points between the connector 130 and the first guide rail 110, and between the connector 130 and the second guide rail 120, may be surface-treated. The surface treatment may include, but is not limited to, electrophoresis, painting, anodizing, etc., to minimize the appearance of seams at the connection points.

[0080] In one embodiment, the connecting body 131 is provided with a clearance portion 130a. The first slide rail 110a, the clearance portion 130a, and the second slide rail 120a are sequentially connected. Thus, the clearance portion 130a of the connecting body 131 is designed to ensure that the first slide rail 110a, the clearance portion 130a, and the second slide rail 120a form a smooth sliding channel, preventing the lifting and lowering of the movable window glass from becoming stuck.

[0081] In one embodiment, the connecting body 131 has a first connecting portion 131a and a second connecting portion 131b disposed opposite to each other along the length direction X. The first guide rail 110 has a first wall surface 110c and a second wall surface 110d disposed opposite to each other along the length direction X; the second guide rail 120 has a third wall surface 120c and a fourth wall surface 120d disposed opposite to each other along the length direction X. The first wall surface 110c and the third wall surface 120c are disposed adjacent to each other, and the third wall surface 120c is connected to the first connecting portion 131a, and the fourth wall surface 120d is connected to the second connecting portion 131b.

[0082] Thus, by connecting the third wall surface 120c to the first connecting part 131a and the fourth wall surface 120d to the second connecting part 131b, the overlapping arrangement of the connecting body 131 with the first slide groove 110a and the second slide groove 120a can be avoided, thereby preventing the formation of protrusions when flowing between the first slide groove 110a, the avoidance part 130a and the second slide groove 120a, thereby improving the smoothness of the sliding of the car window movable glass when sliding between the first slide groove 110a, the avoidance part 130a and the second slide groove 120a.

[0083] It should be noted that the connection method between the connecting body 131 and the first guide rail 110 and the second guide rail 120 can be, but is not limited to, welding, or any combination of one or more of them, such as bonding, screwing, or riveting.

[0084] In one embodiment, the connecting body 131 is welded to at least one of the first guide rail 110 and the second guide rail 120. This welding connection method is convenient to manufacture and eliminates the need for additional mechanical fixing structures, thus reducing manufacturing costs and improving manufacturing efficiency. Furthermore, the welding connection method helps to reduce the connection gap between the connecting body 131 and the first guide rail 110 and the second guide rail 120, thereby improving the robustness between the connecting body 131 and the guide rails and enhancing the operational stability of the movable window glass on the guide rail assembly 100.

[0085] In one example, the first connecting part 131a and the first wall surface 110c are welded together. This welded connection reduces protrusions and gaps between the first connecting part 131a and the first wall surface 110c, thereby ensuring a smooth transition between the first sliding groove 110a and the clearance part 130a, and improving the smoothness and stability of the movement of the movable window glass between the clearance part 130a and the first sliding groove 110a.

[0086] In another example, the second connecting part 131b and the second guide rail 120 are welded together. Similarly, the welded connection reduces the protrusions and gaps between the second connecting part 131b and the third wall surface 120c, thereby ensuring a smooth transition between the second slide rail 120a and the clearance part 130a, and improving the smoothness and stability of the movement of the movable window glass between the clearance part 130a and the second slide rail 120a.

[0087] In another embodiment, the connecting body 131 is mechanically connected to at least one of the first guide rail 110 and the second guide rail 120.

[0088] In one example, one of the connecting body 131 and the first guide rail 110 is provided with a first locking member, and the other of the connecting body 131 and the guide rail assembly 100 is provided with a first mating part. The first locking member and the first mating part are detachably connected. When the first locking member and the first mating part are connected, the connecting body 131 is connected to the first guide rail 110. This detachable connection of the first locking member and the first mating part helps to improve the connection stability and reliability between the connecting body 131 and the first guide rail 110 through a mechanical connection, thereby ensuring the movement stability of the movable window glass when it moves between the clearance part 130a and the first sliding groove 110a.

[0089] In another example, one of the connecting body 131 and the second guide rail 120 is provided with a second locking member, and the other of the connecting body 131 and the guide rail assembly 100 is provided with a second mating part. The second locking member and the second mating part are detachably connected. Similarly, the detachable connection of the second locking member and the second mating part helps to improve the connection stability and reliability between the connecting body 131 and the second guide rail 120 through mechanical connection, thereby ensuring the movement stability of the movable window glass when it moves between the clearance part 130a and the second slide rail 120a.

[0090] The first locking element and the second locking element can be bolts, screws, or snap-fit ​​elements, while the first mating part and the second mating part can be screw holes, threaded grooves, or snap-fit ​​recesses that match the first locking element.

[0091] In conjunction with any embodiment of the connector 130 described above, in conjunction with Figure 6 as well as Figure 7 As shown, the connector 130 also includes a first reinforcing member 132, which is connected to the connector body 131 and is connected to the wall of at least one of the first guide rail 110 and the second guide rail 120.

[0092] Understandably, the connecting body 131 is positioned between the first guide rail 110 and the second guide rail 120, and this location is susceptible to load or vibration, potentially leading to unstable connections between the connecting body 131 and the first guide rail 110 and the second guide rail 120. Therefore, the first reinforcing member 132 is connected to the wall of at least one of the first guide rail 110 and the second guide rail 120, thereby increasing the connection area between the connecting member 130 and at least one of the first guide rail 110 and the second guide rail 120, thus improving the connection stability between the connecting member 130 and at least one of the first guide rail 110 and the second guide rail 120. Furthermore, when the connecting body 131 is subjected to large vibrations or excessive loads, the stress can be dispersed on the walls of the first guide rail 110 and the second guide rail 120 by the first reinforcing member 132, thereby achieving multi-directional stress dispersion, reducing the structural stress between the connecting body 131 and at least one of the first guide rail 110 and the second guide rail 120, avoiding deformation or even separation between the connecting member 130 and the first guide rail 110 and the second guide rail 120, and ensuring the stability and smoothness of the movement of the movable window glass.

[0093] It should be noted that the connection between the first reinforcing member 132 and at least one of the first guide rail 110 and the second guide rail 120, as well as the connection between the first reinforcing member 132 and the connecting body 131, can be, but is not limited to, non-removable connection methods such as bonding or welding, or removable connection methods such as snap-fit ​​or screw-fit. No further restrictions are imposed here.

[0094] In one example, the first reinforcing member 132 is welded to the wall surface of at least one of the first guide rail 110 and the second guide rail 120. This welding connection method simplifies processing and eliminates the need for additional fixing components, thus reducing processing costs and improving processing efficiency.

[0095] In another example, the connecting body 131 and the first reinforcing member 132 are integrally formed.

[0096] Thus, on the one hand, the integral molding of the connecting body 131 and the first reinforcing member 132 can strengthen their structural strength. On the other hand, the integral molding of the connecting body 131 and the first reinforcing member 132 reduces the generation of connection gaps, thereby avoiding the problem of connection loosening caused by long-term use or environmental factors, and also preventing the entry of foreign objects to avoid blocking the movement of the movable window glass, thus improving the movement stability of the movable window glass.

[0097] Furthermore, in some embodiments, see back Figure 6 as well as Figure 7The first reinforcing member 132 includes a first connecting edge 1321 and a second connecting edge 1322; the first connecting edge 1321, the second connecting edge 1322, and the connecting body 131 are arranged at an angle to each other and are connected to each other in pairs, so that the first reinforcing member 132 and the connecting body 131 surround and cooperate to form a triangular structure 132a. The first connecting edge 1321 is connected and cooperates with the first guide rail 110 or the second guide rail 120.

[0098] Since the first reinforcing member 132 and the connecting body 131 are arranged together to form a triangular structure 132a, and the triangular structure 132a has stability, the first reinforcing member 132 and the connecting body 131 can effectively resist forces and torques from different directions, reducing the risk of deformation or detachment of at least one of the connecting body 131, the first guide rail 110 and the second guide rail 120, thereby improving the operational stability of the movable window glass on the guide rail assembly 100.

[0099] Additionally, optionally, in one embodiment, see back Figure 6 In the triangular structure 132a, the included angle between the first connecting side 1321 and the wall of the connecting body 131 is α, where 60°≤α≤120°. Thus, since the connecting body 131 is positioned along the length X between the first guide rail 110 and the second guide rail 120, when deformation occurs between the first guide rail 110 and the second guide rail 120, either the first guide rail 110 or the second guide rail 120 will exert stress on the first reinforcing member 132. When the included angle α is between 60° and 120°, it can effectively disperse the stress, making the stress dispersion faster and more uniform. This reduces the risk of deformation between the first guide rail 110, the connecting body 131, and the second guide rail 120, which helps improve the structural strength of the connecting member 130 and ensures the stability of the movable window glass.

[0100] In one example, 75° ≤ a ≤ 105°. In another example, a = 60°, 75°, 90°, 105°, or 120°.

[0101] Thus, when the included angle α is within this limited range, stress can be further effectively dispersed, the overall structural strength of the connector 130 can be improved, the connector 130 can stably cope with various complex working conditions, which is conducive to ensuring the operational stability of the movable window glass and extending the service life of the guide rail assembly 100.

[0102] In one embodiment, see back Figure 6 as well as Figure 7As shown, the extension direction of the first connecting edge 1321 is parallel to the length direction X. This parallel alignment of the first connecting edge 1321 with the length direction X maximizes the impact area when the wall surface of at least one of the first guide rail 110 and the second guide rail 120 impacts the first connecting edge 1321. This facilitates uniform stress distribution and improves the connection strength between the connector 130 and the first guide rail 110 or the second guide rail 120.

[0103] In conjunction with any of the above embodiments of the connecting body 131, see back Figure 6 The connecting body 131 includes a first body 1311 and a second body 1312. The first body 1311 is connected between the first guide rail 110 and the second guide rail 120. The first body 1311 and the second body 1312 are connected at an angle, forming a clearance portion 130a between the first body 1311 and the second body 1312. The first reinforcing member 132 is connected to the second body 1312.

[0104] Thus, the first body 1311 is connected between the first guide rail 110 and the second guide rail 120, while the second body 1312 is used to connect with the first reinforcing member 132. This avoids spatial interference between the clearance part 130a and the first reinforcing member 132, reducing manufacturing difficulty. Furthermore, the second body 1312 enhances the structural strength of the connecting body 131 and increases its volume, thereby better handling impact stresses from different directions and reducing the risk of deformation or even detachment between the connecting member 130 and the first guide rail 110 and the second guide rail 120.

[0105] Specifically, in one embodiment, see back Figure 1 as well as Figure 6 The first body 1311 is coplanar with the groove wall of at least one of the first slide groove 110a and the second slide groove 120a.

[0106] This ensures smooth movement of the first slide rail 110a, the clearance portion 130a, and the second slide rail 120a, preventing the movable window glass from wobbling during movement. Furthermore, the coplanar arrangement helps to more effectively transfer stress to the wall surface of at least one of the first guide rail 110 and the second guide rail 120 when the first body 1311 is subjected to external force, thereby enhancing the structural strength of the guide rail assembly 100.

[0107] In some embodiments, such as Figure 6 as well as Figure 8 As shown, the connector 130 also includes a second reinforcing member 133, which is connected to the connector body 131 and is disposed between the first connecting part 131a and the second connecting part 131b.

[0108] Thus, the provision of the second reinforcing member 133 can increase the structural stress between the first connecting part 131a and the second connecting part 131b, thereby preventing the connection between the connecting member 130 and the first guide rail 110 and the second guide rail 120 from separating, and ensuring the movement stability of the movable window glass.

[0109] In addition to the connection of the first guide rail 110 and the second guide rail 120 through the connection member 130 in the above embodiments, the docking of the first slide groove 110a and the second slide groove 120a can also be achieved through the direct connection between the first guide rail 110 and the second guide rail 120.

[0110] In some embodiments, such as Figure 9 as well as Figure 10 As shown, the first guide rail 110 and the second guide rail 120 are inserted and engaged, with a portion of the first guide rail 110 and a portion of the second guide rail 120 overlapping each other, and a portion of the bottom wall of the first groove 110a abutting against a portion of the bottom wall of the second groove 120a. That is, in one example, the first guide rail 110 is slidably disposed in the second groove 120a. In another example, the second guide rail 120 is slidably disposed in the first groove 110a.

[0111] Thus, the insertion and engagement of the first guide rail 110 and the second guide rail 120 makes the first slide groove 110a and the second slide groove 120a more stable when they are connected, reducing the shaking caused by loose connections. Furthermore, part of the bottom wall of the first slide groove 110a abuts against part of the bottom wall of the second slide groove 120a, further enhancing the connection strength between the first guide rail 110 and the second guide rail 120, preventing installation wobbling between the first guide rail 110 and the second guide rail 120, and making the movable window glass more stable when moving.

[0112] It should be noted that the connection between the first guide rail 110 and the second guide rail 120 can be, but is not limited to, bonding, welding, snap-fitting, screwing, etc., and no further restrictions are imposed here.

[0113] Optionally, in one embodiment, the first guide rail 110 and the second guide rail 120 are welded together.

[0114] Thus, the welding fit between the first guide rail 110 and the second guide rail 120 ensures a strong connection between them, improves structural strength, and avoids movement jamming or noise problems caused by uneven welding. Furthermore, the welding fit simplifies the assembly process, improves production efficiency, and reduces production costs.

[0115] To improve the welding efficiency between the first guide rail 110 and the second guide rail 120, some embodiments, such as Figure 9 as well as Figure 10 As shown, the width of the first groove 110a along the width direction Y is different from that of the second groove 120a along the width direction Y. This results in a welding gap between the first guide rail 110 and the second guide rail 120 in the width direction Y when they are inserted and mated. It is understood that the welding gap helps in the insertion of the welding torch or welding material, allowing the first guide rail 110 and the second guide rail 120 to weld together through the gap. This improves the accuracy of the welding alignment and the welding efficiency between the first guide rail 110 and the second guide rail 120.

[0116] Specifically, a portion of the first guide rail 110 and a portion of the second guide rail 120 are arranged to overlap in the depth direction Z to form an overlapping region 100a.

[0117] In one embodiment, such as Figure 11 As shown, within the overlapping region 100a, the thickness of the groove wall of the first guide rail 110 and the second guide rail 120 superimposed in the depth direction Z is D, where D≥1mm.

[0118] Thus, the design of the superimposed groove wall thickness D ensures a stable connection between the first guide rail 110 and the second guide rail 120 in the depth direction Z, meets the load-bearing performance requirements of the guide rail assembly 100, and enhances the overall strength and stability of the guide rail assembly 100.

[0119] In one example, D ≥ 1.5 mm. In another example, D = 2 mm, 3 mm, 4 mm, or 5 mm, etc.

[0120] Thus, within this range, the guide rail assembly 100, which can provide higher load-bearing capacity and higher structural strength through the overlapping area 100a, can effectively resist external loads and ensure the stability and reliability of the guide rail assembly 100.

[0121] In another embodiment, see back Figure 10 The overlap length of the overlapping region 100a in the length direction X is L, where L≥3mm. This ensures that the connection area between the first guide rail 110 and the second guide rail 120 is large enough, thereby achieving a stable connection between the first guide rail 110 and the second guide rail 120.

[0122] In one example, L ≥ 5 mm. In another example, L can be any value such as 6 mm, 8 mm, 10 mm, or 12 mm. By designing the overlap length L in this way, the connection strength between the first guide rail 110 and the second guide rail 120 in the length direction X can be further increased, thereby improving the stable operation performance of the guide rail assembly 100.

[0123] In some embodiments, such as Figure 3As shown, in conjunction with any embodiment of the second body 1312 described above, the second body 1312 may be provided with a connection hole 131c. The connection hole 131c is used to connect and cooperate with the body sheet metal or door frame through fasteners such as pins and screws, thereby improving the installation stability of the connector 130.

[0124] Furthermore, in other embodiments, such as Figure 3 As shown, the second body 1312 may also be provided with a weight reduction hole 131d. In this way, by providing the weight reduction hole 131d, the weight of the connector 130 can be reduced, thereby improving the portability of the guide rail assembly 100.

[0125] 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.

[0126] 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.
