[0050] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be 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 the present invention. However, the present invention can be practiced 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 the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0051] In some embodiments of this application, such as Figures 1-4 As shown, a skylight operation channel 10 includes a hollow tube 11 and an end piece 12. The hollow tube 11 includes an outer pipe 111 and an inner pipe 112. The end piece 12 includes a first end 121 and a second end 122. One end of the outer pipe 111 and the inner pipe 112 is connected to the first end 121, and the other end of the inner pipe 112 is connected to the second end 122. The end piece 12 is used for installation on a skylight glass 21. The end piece 12 includes an upper part 123 away from the skylight glass 21 and a lower part 124 close to the skylight glass 21. The side of the upper part 123 away from the skylight glass 21 is an upper surface 1230. The upper part 123 is provided with a mating hole 125 communicating with the hollow tube 11, and the lower part 124 is provided with an extension 126 for installation on the skylight glass 21.

[0052] The inner pipe 112 of the hollow tube 11 is used for the movement of the cable 25 to drive the sunshade to open or close, and the outer pipe 111 of the hollow tube 11 is used for the retraction of the cable 25; the end piece 12 can play a positioning role in the mold; the hollow tube 11 is set in the mating hole 125 of the upper part 123, and the extension 126 of the lower part 124 is installed on the sunroof glass 21. There is a height difference between the upper part 123 and the lower part 124, which can prevent the hollow tube 11 from being deformed and damaged due to direct contact with the sunroof glass 21.

[0053] In one embodiment, such as Figures 1-4 As shown, the extension 126 is provided with a buffer portion 1261 for connecting with the sunroof glass 21. The main function of the buffer portion 1261 of the lower component 124 is to buffer the hollow tube 11 when the upper mold is pressed down, so as to prevent the hollow tube 11 from being deformed or damaged due to direct contact between the hollow tube 11 and the sunroof glass 21.

[0054] Preferably, such as Figure 4 As shown, the interference between the buffer part 1261 and the sunroof glass 21 is A, and 1mm≤A≤2mm.

[0055] It should be noted that, Figure 4The buffer section 1261 has not yet deformed. After the buffer section 1261 deforms, the buffer section 1261 will not penetrate into the sunroof glass 21.

[0056] Furthermore, the material of the buffer portion 1261 is a thermoplastic elastomer. Thermoplastic elastomers (TPEs) possess excellent properties such as high elasticity, aging resistance, and oil resistance, while also being easy to process and available in a wide range of processing methods. This ensures that the buffer portion 1261 of the lower component 124 is less prone to plastic deformation or breakage under stress.

[0057] In one embodiment, such as Figures 2-3 As shown, the upper surface 1230 of the upper component 123 is provided with a first positioning part 1231 for positioning in the mold.

[0058] A first mating part is provided in the mold to cooperate with the first positioning part 1231. When the end piece 12 is in contact with the mold surface, the first positioning part 1231 and the first mating part cooperate to achieve precise positioning of the hollow tube 11 in the mold.

[0059] Preferably, the first positioning part 1231 is a recess or a boss. When the first positioning part 1231 is a recess, the first mating part is a boss that adapts to the recess; when the first positioning part 1231 is a boss, the first mating part is a recess that adapts to the boss.

[0060] In one embodiment, such as Figures 2-3 As shown, the extension 126 is further provided with a second positioning part 1262 for positioning in the mold.

[0061] A second mating part is provided in the mold to cooperate with the second positioning part 1262. When the end piece 12 is in contact with the mold surface, the second positioning part 1262 and the second mating part cooperate to achieve precise positioning of the hollow tube 11 in the mold.

[0062] Preferably, the second positioning part 1262 is a positioning hole. In this case, a positioning pin that mates with the positioning hole is provided in the mold, and the end piece 12 can achieve precise positioning in the mold by engaging the positioning hole with the positioning pin. It should be noted that the number of positioning holes can be one or more, depending on the actual positioning requirements.

[0063] In one embodiment, the upper surface 1230 of the upper component 123 has a mounting hole 1232, and a nut 1233 is provided in the mounting hole 1232.

[0064] The mounting hole 1232 can be used to cooperate with the positioning pin in the mold to improve the positioning accuracy of the hollow tube 11 in the mold; the nut 1233 can be used to cooperate with the bolt to lock the motor to the motor mounting part 22.

[0065] Preferably, the end piece 12, the hollow tube 11, and the nut 1233 are integrally injection molded, thereby further simplifying the manufacturing and assembly processes.

[0066] Furthermore, in some embodiments of this application, such as Figures 5-7 As shown, a sunroof assembly 20 is provided, comprising:

[0067] Sunroof glass 21;

[0068] Motor mounting part 22 is installed on the sunroof glass 21;

[0069] Two canopy operation channels 10 as described above are injection molded together and fixed to the skylight glass 21 via edging 24; two canopy operation channels 10 are respectively provided at both ends of the motor mounting part 22; and

[0070] Two guide rails 23, one end of each guide rail 23 is aligned with the two second ends 122 respectively, and the two guide rails 23 are arranged in parallel; the guide rails 23 and the canopy running channel 10 form a pipe for the cable 25 to be driven.

[0071] The structural design of the hollow tube 11 and end piece 12 in the canopy operation channel 10 allows for more precise positioning of the hollow tube 11 during injection molding and edging 24. Furthermore, integrating the hollow tube 11 into the glass edging 24 solves problems such as vibration, abnormal noise, and detachment of the hollow tube 11, effectively fixing it in place. It also eliminates the need for the plastic crossbeams found in existing technologies, simplifying component assembly processes, reducing roof height, optimizing costs, and enhancing market competitiveness.

[0072] In this embodiment, the material of the skylight glass 21 is not limited, and it is usually inorganic glass, organic glass, or composite material; the material of the guide rail 23 is not limited, and it is usually plastic or metal; the material of the edging 24 is not limited, and it is usually polyvinyl chloride (PVC), thermoplastic elastomer (TPE), ethylene propylene diene monomer (EPDM), or polyurethane (PU), etc.

[0073] In one embodiment, such as Figure 5As shown, the hollow tube 11 is provided with a plurality of process clamping parts 26, which are arranged sequentially at intervals along the arrangement path of the hollow tube 11, and the process clamping parts 26 expose the edge 24.

[0074] During the injection molding of the edge banding 24, the process clamping part 26 can engage with the gripper (not shown in the figure) to adjust the orientation of the hollow tube 11. Since the process clamping part 26 is exposed on the edge banding 24, the gripper (not shown in the figure) can be removed from the hollow tube 11 after the edge banding 24 is injection molded.

[0075] Furthermore, the hollow tube 11 includes a first straight tube section 113 connected to the motor mounting part 22, a second straight tube section 114 arranged along the guiding direction of the guide rail 23, and a curved section 115 for connecting the first straight tube section 113 and the second straight tube section 114. At least one of the process clamping parts 26 is disposed in the first straight tube section 113, and at least one of the process clamping parts 26 is disposed in the curved section 115.

[0076] At least one of the process clamping parts 26 is disposed on the first straight pipe section 113 to ensure the stability of the first straight pipe section 113 and improve the axial positioning accuracy between the mating holes 125 of the two first ends 121 communicating with the outer pipe 111 and the axial positioning accuracy between the mating holes 125 of the two first ends 121 communicating with the inner pipe 112; at least one of the process clamping parts 26 is disposed on the curved section 115 so that the hollow pipe 11 can form a stable bending arc.

[0077] It should be noted that the process clamping part 26 can also be provided in the second straight pipe section 114. The process clamping part 26 provided in the second straight pipe section 114 can be used to ensure the stability of the second straight pipe section 114 and improve the axial positioning accuracy between the two second ends 122 and the adjacent guide rail 23.

[0078] Preferably, the length of the process clamping part 26 is B, and 10mm≤B≤20mm, such as 10mm, 12mm, 14mm, 16mm, 18mm or 20mm.

[0079] In one embodiment, the concentricity error between the mating holes 125 of the two first ends 121 communicating with the outer pipe 111 is ±0.3mm; the concentricity error between the mating holes 125 of the two first ends 121 communicating with the inner pipe 112 is ±0.3mm, so as to prevent abnormal noise when the cable 25 slides at the transition position of the two first ends 121.

[0080] In one embodiment, the concentricity error between the mating holes 125 of the two second ends 122 and the adjacent guide rail 23 is ±0.3mm, to prevent abnormal noise when the cable 25 slides at the transition position between the second end 122 and the adjacent guide rail 23.

[0081] Furthermore, such as Figures 6-7 As shown, the hollow tube 11 is encased in the edging 24, and the lower component 124 is also encased in the edging 24. The hollow tube 11 and the lower component 124 of the end piece 12 are connected to the sunroof glass 21 through the edging 24, eliminating the large plastic crossbeam in the prior art, simplifying the assembly process of the parts, and achieving a reduction in roof height space and cost optimization.

[0082] Furthermore, such as Figure 5 As shown, the other end of the outer pipe 111 is exposed above the edging 24.

[0083] In some embodiments of this application, a vehicle is provided, including a motor (not shown) and a sunroof assembly 20 as described above; the motor (not shown) is mounted on the motor mounting portion 22.

[0084] The structural design of the hollow tube 11 and end piece 12 in the aforementioned vehicle allows for more precise positioning of the hollow tube 11 during injection molding and edging 24, ensuring the concentricity requirements between the two first ends 121 and between the second end 122 and the adjacent guide rail 23, thus preventing abnormal noises from occurring in the operating channel when the cable 25 moves. Furthermore, integrating the hollow tube 11 into the glass edging 24 solves problems such as vibration, abnormal noise, and detachment of the hollow tube 11, effectively fixing it in place. It also eliminates the need for the plastic crossbeams in existing technologies, simplifying the assembly process, reducing the roof height space, optimizing costs, and enhancing market competitiveness.

[0085] In one embodiment, the motor (not shown in the figure) is fastened to the motor mounting part 22 by bolts (not shown in the figure) engaging with the nut 1233 of the end piece 12.

[0086] It should be noted that the edge band 24 may also be provided with a nut located between the nuts 1233 of the two end pieces 12. This nut, together with the nuts 1233 of the two end pieces 12, is used to cooperate with the bolt (not shown in the figure) to lock the motor (not shown in the figure) to the motor mounting part 22.

[0087] It should be noted that, in this invention, if the skylight glass 21 is an inorganic glass, examples include soda-lime glass (also known as soda-lime silicate glass), aluminosilicate glass, borosilicate glass, lithium aluminum silicate glass, alkali-free glass, and quartz glass. Soda-lime glass is particularly preferred among these. From the perspective of improving strength, inorganic glass can also be tempered glass, which can be either chemically strengthened glass or physically strengthened glass.

[0088] If the skylight glass 21 is made of plexiglass (resin), examples include polycarbonate resin, polystyrene resin, aromatic polyester resin, acrylic resin, polyester resin, polyarylate resin, condensation polymers of halogenated bisphenol A and ethylene glycol, urethane acrylate resin, and acrylic resin containing halogenated aryl groups. Among these, aromatic polycarbonate resins and other polycarbonate resins, as well as polymethyl methacrylate acrylic resins and other acrylic resins, are preferred; polycarbonate resins are more preferred; and bisphenol A polycarbonate resins are particularly preferred. Furthermore, two or more of the above resins may be used in combination.

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