[0049] 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.

[0050] like Figure 1-2 As shown, in some embodiments of this application, a transmission assembly 10 is provided, including: a synchronous belt 11, a sliding mechanism 12, and a fixing member 13. The sliding mechanism 12 includes a sliding portion 122 and a connecting portion 121 that are spaced apart. The fixing member 13 is spaced apart from the sliding portion 122. The synchronous belt 11 is disposed between the fixing member 13 and the connecting portion 121. The fixing member 13 is connected to the connecting portion 121 so that the synchronous belt 11 is fixed to the connecting portion 121.

[0051] It should be noted that, in this embodiment, the timing belt 11 is positioned between the fixing member 13 and the connecting part 121, and the fixing member 13 is connected to the connecting part 121, thereby fixing the timing belt 11 to the connecting part 121. Since the fixing member 13 is directly connected to the connecting part 121 of the sliding mechanism 12, no tooling is needed for positioning, simplifying the installation process and improving the ease of assembly and disassembly of the fixing member 13 and the connecting part 121.

[0052] It should be noted that, in this embodiment, the synchronous belt 11 can be an open belt or a closed-loop belt. The open belt is a straight belt whose two ends are not connected together; the closed-loop belt is an annular belt formed by connecting the two ends of the open belt together.

[0053] In one embodiment, such as Figure 2 , 3 As shown in Figure 6, the connecting portion 121 includes a bottom 1212 and a positioning groove 1211 extending from the bottom 1212. The positioning groove 1211 and the bottom 1212 form a clamping portion 1213, so that the synchronous belt 11 is clamped in the clamping portion 1213.

[0054] It should be noted that, in this embodiment, by providing the clamping part 1213 on the connecting part 121 of the sliding mechanism 12, the synchronous belt 11 is clamped in the clamping part 1213. The clamping part 1213 can pre-position the synchronous belt 11, ensuring the positioning accuracy of the synchronous belt 11 and the connecting part 121 of the sliding mechanism 12, avoiding the risk of misalignment; and preventing the synchronous belt 11 from displacing from the connecting part 121 during installation.

[0055] In this embodiment, the timing belt 11 further includes an outer surface 111 and an inner surface 112 disposed opposite to each other. The outer surface 111 of the timing belt 11 abuts against the bottom 1212 of the connecting portion 121, and the inner surface 112 of the timing belt 11 abuts against the positioning groove 1211.

[0056] It should be noted that, in this embodiment, since the outer surface 111 of the synchronous belt 11 abuts against the bottom 1212 of the connecting part 121, and the inner surface 112 of the synchronous belt 11 abuts against the positioning groove 1211, the synchronous belt 11 and the clamping part 1213 fit tightly together, which further improves the pre-positioning effect of the connecting part 121 and the synchronous belt 11, ensures the positioning accuracy of the connecting part 121 of the synchronous belt 11 and the sliding mechanism 12, and avoids the risk of misalignment; and also avoids the synchronous belt 11 from displacing from the connecting part 121 during installation.

[0057] In this embodiment, further, as Figure 2 , 6 As shown, the inner surface 112 of the synchronous belt 11 is provided with at least two protruding teeth 1121, and the positioning groove 1211 is provided with at least two grooves 1214 for cooperating with the protruding teeth 1121, and the protruding teeth 1121 mesh with the grooves 1214.

[0058] It should be noted that, in this embodiment, by engaging the protruding teeth 1121 with the groove 1214, the contact area between the inner surface 112 of the synchronous belt 11 and the positioning groove 1211 is increased, which further improves the clamping firmness of the synchronous belt 11 and the clamping part 1213, thereby improving the pre-positioning effect of the synchronous belt 11 and the connecting part 121.

[0059] In one embodiment, such as Figure 4 As shown, the fixing member 13 is provided with a receiving hole 132 for accommodating the positioning groove 1211.

[0060] It should be noted that, in this embodiment, by providing the receiving hole 132, the situation where the fixing member 13 and the connecting part 121 cannot be connected due to interference from the positioning groove 1211 when the fixing member 13 is connected to the connecting part 121 is avoided.

[0061] In this embodiment, the receiving hole 132 is further pressed against the positioning groove 1211.

[0062] It should be noted that, in this embodiment, the positioning groove 1211 is pressed together with the receiving hole 132, thereby further engaging the positioning groove 1211 with the timing belt 11 and improving the fixing strength between the timing belt 11 and the connecting part 121.

[0063] In this embodiment, further, as Figure 4As shown, the surface of the fixing member 13 that contacts the protruding tooth 1121 is provided with at least two recesses 133 for cooperating with the protruding tooth 1121. The recesses 133 are provided with the receiving hole 132, and the protruding tooth 1121 engages with the recesses 133.

[0064] It should be noted that, in this embodiment, by providing at least two recesses 133 on the surface of the fixing member 13 that contact the protruding teeth 1121 for engaging with the protruding teeth 1121, after the fixing member 13 is connected to the connecting part 121 of the sliding mechanism 12, the protruding teeth 1121 of the synchronous belt 11 engage with the recesses 133 of the fixing member 13 and the grooves 1214 of the positioning groove 1211, thereby improving the tight fit between the synchronous belt 11 and the fixing member 13 and the connecting part 121, and thus ensuring the operational stability of the synchronous belt 11.

[0065] In one embodiment, such as Figure 2-4 As shown in Figure 6, the fastener 13 is provided with a buckle 131, and the bottom 1212 of the connecting part 121 is provided with a slot 1215 for cooperating with the buckle 131, and the buckle 131 is fixed to the slot 1215.

[0066] It should be noted that in this embodiment, the fastener 13 is engaged with the latch 1215 provided at the bottom 1212 of the connecting part 121 by the buckle 131, without the need for tooling to assist in positioning, which simplifies the installation process and further improves the ease of assembly and disassembly of the fastener 13 and the connecting part 121.

[0067] In one embodiment, such as Figure 2 , 10 As shown, the width direction of the synchronous belt 11 is Y-direction, the thickness direction of the synchronous belt 11 is Z-direction, the connecting part 121 and the sliding part 122 are arranged side by side along the Y-direction, and the connecting part 121 and the fixing member 13 are arranged along the Z-direction.

[0068] It should be noted that, in this embodiment, during loading, the Y direction may sometimes be the width direction of the vehicle, and the Z direction may sometimes be the height direction of the vehicle.

[0069] In this embodiment, further, as Figure 3 As shown, the positioning groove 1211 extends in the Y direction.

[0070] It should be noted that, in this embodiment, during installation, the timing belt 11 is inserted into the clamping part 1213 along the Y direction.

[0071] In this embodiment, further, as Figure 3As shown, the number of the bayonet 1215 is at least two, and the number of the buckles 131 is the same as the number of the bayonet 1215. The two bayonet 1215 are arranged along the Y direction on both sides of the synchronous belt 11.

[0072] It should be noted that, in this embodiment, the two latches 1215 are arranged on both sides of the synchronous belt 11 along the Y direction, so that when the buckle 131 is engaged with the latch 1215, it can limit the two sides of the synchronous belt 11 in the Y direction, preventing the synchronous belt 11 from falling off in the Y direction during operation, and ensuring the connection stability of the synchronous belt 11 and the connection part 121 of the sliding mechanism 12.

[0073] It should be noted that, in this embodiment, at least two of the bayonets can be symmetrically arranged on both sides of the synchronous belt 11 along the Y direction, or they can be asymmetrically arranged on both sides of the synchronous belt 11, and no limitation is made here.

[0074] In this embodiment, further, as Figure 2 , 4 As shown, the buckle 131 includes a connected side portion 1311 and a hook portion 1312, the side portion 1311 and the hook portion 1312 forming a hook groove 1313, the hook groove 1313 being fixed to the latch 1215. The hook groove 1313 cooperates with the latch 1215, causing the fixing member 13 to engage with the connecting portion 121 of the sliding mechanism 12.

[0075] In one embodiment, such as Figure 2 , 6 As shown, the synchronous belt 11 is an open belt, and there are two positioning grooves 1211. The two positioning grooves 1211 are arranged at intervals relative to each other, and the two ends 113 of the open belt are respectively arranged in the two clamping parts 1213.

[0076] It should be noted that in this embodiment, the synchronous belt 11 is an open belt. Open belts have high wear resistance, small tolerance, and stable and reliable dimensions. In particular, they can maintain unchanged operating characteristics in application and ensure good operation skills under high load transmission.

[0077] It should be noted that, in this embodiment, by setting two positioning grooves 1211, the two ends 113 of the open belt are respectively set in the two clamping parts 1213, which realizes the pre-positioning of the synchronous belt 11 and the connecting part 121, ensures the positioning accuracy of the connecting part 121 of the synchronous belt 11 and the sliding mechanism 12, and avoids the risk of misalignment.

[0078] In this embodiment, further, as Figure 2-3As shown, a stop portion 1217 is provided between the two positioning grooves 1211, and the stop portion 1217 is disposed at the bottom 1212 of the connecting portion 121.

[0079] It should be noted that, in this embodiment, by providing the stop portion 1217 between the two positioning grooves 1211, and by providing the stop portion 1217 at the bottom 1212 of the connecting portion 121, the installation spaces of the two ends 113 of the open strip are separated, and each end 113 of the open strip has its own installation space, further improving the ease of installation of the open strip and the connecting portion 121. In this embodiment, optionally, as... Figure 4 As shown, the fixing member 13 is provided with a mating hole 135 for accommodating the stop part 1217.

[0080] In one embodiment, such as Figure 5-6 As shown, the transmission assembly 10 also includes a locking member 14. Between the two positioning grooves 1211, the bottom 1212 of the connecting part 121 is provided with a first fixing hole 1216, and the fixing member 13 is provided with a second fixing hole 134 aligned with the first fixing hole 1216. The locking member 14 is fixed to the first fixing hole 1216 and the second fixing hole 134.

[0081] It should be noted that, in this embodiment, by setting the locking member 14, the fixing effect between the connecting part 121 and the fixing member 13 is enhanced, and the connection stability between the synchronous belt 11 and the connecting part 121 is further improved.

[0082] In one embodiment, such as Figure 7-8 As shown, the transmission assembly 10 also includes a guide rail 15 and two pulleys 16 respectively disposed at both ends of the guide rail 15. The synchronous belt 11 is disposed between the two pulleys 16 and the synchronous belt 11 is in transmission cooperation with the two pulleys 16 respectively.

[0083] It should be noted that in this embodiment, the material of the guide rail 15 is not limited, and it is usually made of plastic or metal.

[0084] It should be noted that, in this embodiment, the connecting part 121 of the sliding mechanism 12 can be disposed outside the guide rail 15 or inside the guide rail 15, and there is no limitation here.

[0085] In this embodiment, further, as Figure 9-10 As shown, the guide rail 15 includes a sliding channel 152 for accommodating the sliding part 122. The sliding part 122 is disposed in the sliding channel 152, and the sliding part 122 slides in cooperation with the sliding channel 152.

[0086] It should be noted that in this embodiment, the movement of the sliding part 122 drives the movement of the connecting part 121, which in turn drives the synchronous belt 11 fixed on the connecting part 121 to move. The synchronous belt 11 drives the two pulleys 16 to rotate, thereby realizing the transmission function of the transmission assembly 10.

[0087] In this embodiment, further, as Figure 9-10 As shown, the guide rail 15 also includes a connecting channel 151 arranged side by side with the sliding channel 152. The connecting part 121 and the fixing member 13 are both disposed in the connecting channel 151, and the connecting part 121 and the fixing member 13 are both clearance-fitted with the connecting channel 151.

[0088] It should be noted that, in this embodiment, since the connecting part 121 and the sliding part 122 have different channels within the guide rail 15, both the connecting part 121 and the fixing member 13 are disposed within the connecting channel 151, and both the connecting part 121 and the fixing member 13 are clearance-fitted with the connecting channel 151. This ensures that the fixing member 13 is not subjected to force during the operation of the synchronous belt 11, preventing the fixing member 13 from falling off the connecting part 121 and guaranteeing the connection stability between the synchronous belt 11 and the connecting part 121. Furthermore, the dimensional accuracy requirements for the fixing member 13 are lower, allowing for larger tolerances and reducing costs. Additionally, the frictional force experienced by the connecting part 121 during movement is reduced, thereby preventing connection failure between the synchronous belt 11 and the connecting part 121 and further improving the operational stability of the synchronous belt 11.

[0089] It should be noted that, in one embodiment of the present invention, the installation process of the connection portion 121 between the timing belt 11 and the sliding mechanism 12 is as follows:

[0090] Before the sliding mechanism 12 enters the guide rail 15, one end 113 of the synchronous belt 11 is inserted into the clamping part 1213 of the connecting part 121 from the Y direction. The synchronous belt 11 first passes around a pulley 16 located away from the sliding mechanism 12 and then passes around another pulley 16 located close to the sliding mechanism 12. Subsequently, the other end 113 of the synchronous belt 11 is inserted into another clamping part 1213 from the Y direction. Finally, the buckle 131 of the fixing member 13 is snapped into the slot 1215 of the connecting part 121 from the Z direction to complete the installation.

[0091] It should be noted that, in this embodiment, during loading, the Y direction may sometimes be the width direction of the vehicle, and the Z direction may sometimes be the height direction of the vehicle.

[0092] Based on the aforementioned transmission component 10, the present invention also provides a sunroof assembly, including glass (not shown in the figure) and two transmission components 10 as described above, the two transmission components 10 being symmetrically arranged on both sides of the glass (not shown in the figure).

[0093] It should be noted that in this embodiment, the material of the glass (not shown in the figure) is not limited, and it is usually inorganic glass, organic glass, or composite material.

[0094] It should be noted that the sunroof assembly described above, through a simplified structure, allows the fixing member 13 to be directly connected to the connecting part 121 of the sliding mechanism 12, eliminating the need for tooling for positioning. This simplifies the installation process and improves the ease of assembly and disassembly of the fixing member 13 and the connecting part 121. Secondly, by providing the clamping part 1213 on the connecting part 121 of the sliding mechanism 12, the synchronous belt 11 is clamped to the clamping part 1213, enabling pre-positioning of the synchronous belt 11 and ensuring the accurate positioning of the synchronous belt 11 and the connecting part 121 of the sliding mechanism 12, thus avoiding the risk of misalignment. Furthermore, it prevents the synchronous belt 11 from malfunctioning during installation. The displacement phenomenon causes the connecting part 121 to detach. Finally, since the connecting part 121 and the sliding part 122 have different channels within the guide rail 15, and both the connecting part 121 and the fixing member 13 are located within the connecting channel 151 with a clearance fit, the fixing member 13 is not subjected to force during the operation of the synchronous belt 11, preventing it from detaching from the connecting part 121 and ensuring the connection stability between the synchronous belt 11 and the connecting part 121. Furthermore, the dimensional accuracy requirements for the fixing member 13 are lower, allowing for larger tolerances and reducing costs. Additionally, the frictional force experienced by the connecting part 121 during movement is reduced, thus preventing connection failure between the synchronous belt 11 and the connecting part 121 and further improving the operational stability of the synchronous belt 11.

[0095] It should be noted that, in this invention, if the glass (not shown in the figure) 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.

[0096] If the glass (not shown in the figure) is 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.
