Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a sunshade assembly and a glass assembly. Background Technology

[0002] To meet sun shading needs, electric sunshades have been widely used in automotive sunroof systems, providing sun protection and heat insulation. Existing electric sunshades are generally divided into two types based on their drive method: direct-drive and non-direct-drive. Direct-drive sunshades are further divided into two structural forms based on the motor's placement: direct-drive rear-mounted motor and direct-drive front-mounted motor. These sunshades each have their own characteristics in structural design and functional implementation, but all aim to improve sun shading performance and user experience. In existing direct-drive rear-mounted motor sunshades, the motor is located at the rear of the sunshade assembly, driving the rear synchronous pulley to rotate, thereby moving the sunshade. However, because the L-shaped motor has a cantilever structure, the cantilever is prone to swaying during load operation. Furthermore, due to design limitations, the motor can only be positioned along the X-axis of the vehicle, resulting in a large space occupation at the rear of the sunshade assembly in the X-axis direction. This structural form cannot meet the space requirements of some customers who prefer a front-end motor, limiting its application in certain vehicle models. Existing direct-drive front-motor sunshades have the motor positioned at the end furthest from the sunshade roller. The motor's output shaft drives a single-sided front synchronous pulley, and the opening and closing of the sunshade is controlled via a synchronous belt. However, this structure relies solely on a single-sided front synchronous pulley, and the connection between the two pulleys is non-rigid. This results in a lag in the operation of the non-motor side's front synchronous pulley, causing asynchronous operation at both ends of the sunshade rod and impacting the user experience. Therefore, how to meet the requirements for front-end motor placement and better achieve synchronous operation at both ends of the sunshade to improve operational stability and user satisfaction has become a pressing technical problem to be solved.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Implementation Method 1

[0024] Please refer to the following: Figures 1 to 7 As shown, an embodiment of this utility model provides a sunshade curtain assembly, which includes a sunshade structure 100, a synchronous drive mechanism 200, and a support structure 300. The sunshade structure 100 includes a guide rail frame structure 110, a pull rod 120 slidably mounted on the guide rail frame structure 110, a sunshade curtain 130 connected to the pull rod 120, and a synchronous adjustment mechanism 140 for driving the pull rod 120 to slide. The synchronous drive mechanism 200 includes a rotating member 210, a connecting member 220 tractably connected to the rotating member 210, and a drive device 230 for driving the rotating member 210 to rotate. The connecting member 220 is tractably connected to the synchronous adjustment mechanism 140. The support structure 300 is mounted on the guide rail frame structure 110 and is detachably connected to the drive device 230.

[0025] Overall, such as Figure 1 and Figure 2In the illustrated embodiment, the sunshade assembly, by placing the support structure 300 on the side of the guide rail frame structure 110 away from the winding mechanism, can support the drive device 230, thereby improving the structural stability of the drive device 230. In particular, it can effectively limit the swing amplitude of the drive device 230 in the direction perpendicular to the guide rail frame structure 110, that is, limit the swing amplitude of the drive device 230 in the Z direction of the vehicle, and avoid abnormal noise and unstable operation caused by the vibration of the drive device 230, thus meeting the requirements for the front-mounted layout of the drive device 230.

[0026] Furthermore, this invention achieves high-precision synchronous transmission through the cooperation of the rotating component 210, the connecting component 220, and the driving device 230. This enables the pull rod 120 to synchronously adjust both ends of the sunshade curtain 130, effectively avoiding the lag problem caused by unilateral driving and significantly improving the synchronicity of both ends of the sunshade curtain 130. This invention can meet the requirements of the front-end motor arrangement and better achieve synchronous operation of both ends of the sunshade curtain 130, thereby improving operational stability and user satisfaction.

[0027] In the embodiments of this utility model, such as Figure 1 and Figure 2 In the illustrated embodiment, the support structure 300 is disposed on the side of the guide rail frame structure 110 away from the winding mechanism. The guide rail frame structure 110 includes two guide rails 111 disposed opposite to each other, a first front bracket 112 disposed at the front end of one guide rail 111, and a second front bracket 113 disposed at the front end of the other guide rail 111. The support structure 300 includes a front fixing seat 310 disposed on the first front bracket 112 and / or the second front bracket 113. The front fixing seat 310 is located between the first front bracket 112 and the second front bracket 113. The drive device 230 is detachably disposed on the front fixing seat 310.

[0028] The front end of the guide rail 111 refers to the end furthest from the winding mechanism. That is, the winding mechanism's spool and the support structure 300 are respectively positioned on opposite sides of the guide rail 111 in its extension direction.

[0029] In one specific embodiment, the front mounting base 310 is disposed on the first front bracket 112. Preferably, as shown below... Figure 1 and Figure 4 In the illustrated embodiment, the first front bracket 112 extends toward the second front bracket 113 to form a front mounting base 310. By making the first front bracket 112 and the front mounting base 310 integrally formed, the structural strength between them is improved and the installation steps are reduced.

[0030] Furthermore, a support end face for supporting the drive unit 230 is formed on the front mounting base 310. The front mounting base 310 can stably support the drive unit 230, preventing the drive unit 230 from swinging perpendicular to the guide rail frame structure 110 during movement, i.e., swinging in the Z-direction (vehicle height direction), thereby avoiding abnormal noise problems caused by vibration. In addition, the detachable installation method facilitates the assembly and subsequent maintenance of the drive unit 230, resulting in better performance.

[0031] Designers can adjust the specific shape and configuration of the front mounting bracket 310 according to usage needs; no specific limitations are imposed here. For example, such as Figure 4 In the embodiment shown, the front mounting base 310 is generally constructed in a rectangular shape. By extending the front mounting base 310 toward the second front bracket 113, the front mounting base 310 can be placed in the area between the two guide rails 111, making full use of the gap space of the guide rail frame structure 110 and reducing space occupation.

[0032] Furthermore, such as Figure 4 In the embodiment shown, the side edge of the front mounting base 310 away from the guide rail frame structure 110 is bent upward to form a limiting part 312. The limiting part 312 can play a limiting role, improve the installation accuracy of the drive device 230, and prevent the drive device 230 from accidentally detaching from the front mounting base 310.

[0033] In the embodiments of this utility model, such as Figure 5 In the embodiment shown, the front mounting base 310 is provided with a first connecting part 311, the drive device 230 is provided with a second connecting part 231, and the sunshade assembly also includes at least one fastener. The first connecting part 311 and the second connecting part 231 are detachably connected to each other by the fastener.

[0034] By using fasteners for connection, the structural stability of the drive unit 230 during operation can be effectively guaranteed, preventing unstable power transmission caused by loose connections, and further suppressing abnormal noise caused by the swing and vibration of the drive unit 230 in the Z direction.

[0035] Specifically, the first connecting part 311 is provided with a first mounting hole, and the second connecting part 231 is provided with a second mounting hole. Fasteners are inserted into the first mounting hole and the second mounting hole to serve as a connection.

[0036] Designers can adjust the specific structure of the fasteners according to usage requirements, and no specific restrictions are imposed here. For example, both the first and second mounting holes are bolt holes, and the fastener is a bolt.

[0037] Furthermore, multiple first connecting parts 311 and multiple second connecting parts 231 are provided. The synergistic effect of multiple first connecting parts 311 and multiple second connecting parts 231 improves connection stability. Designers can adjust the number and position of the first connecting parts 311 and multiple second connecting parts 231 according to usage needs; no specific limitations are imposed here. For example, two, three, or other quantities of first connecting parts 311 and multiple second connecting parts 231 may be provided.

[0038] In the embodiments of this utility model, the setting position and shape of the front fixing seat 310 can be flexibly adjusted according to the needs of use, so that the driving device 230 can be set in any position, thereby having better arrangement flexibility.

[0039] In the embodiments of this utility model, such as Figure 3 In the embodiment shown, the rotating member 210 includes an output gear 211, the output gear 211 is provided with a transmission hole 212, and the connecting member 220 includes a connecting rod 221 inserted into the transmission hole 212, the connecting rod 221 being tractably connected to the output gear 211.

[0040] By inserting the output gear 211 into the connecting rod 221, the output gear 211 and the connecting rod 221 can rotate synchronously, ensuring the stability and synchronicity of power transmission. Furthermore, the insert-fit method facilitates assembly and maintenance, and also allows both ends of the connecting rod 221 to pass through the output gear 211 for synchronous transmission.

[0041] Designers can adjust the transmission method between the output gear 211 and the connecting rod 221 according to usage requirements, without specific limitations. Preferably, the cross-section of the transmission hole 212 is non-circular, and at least a portion of the cross-section of the connecting member 220 is conformally arranged to the cross-section of the transmission hole 212 and inserted into the transmission hole 212.

[0042] By making the cross-section of the transmission hole 212 non-circular and setting the cross-section of at least part of the connector 220 to conform to the cross-section of the transmission hole 212, when the two are inserted and matched, relative rotation between the output gear 211 and the connecting rod 221 is effectively avoided, ensuring the accuracy and synchronization of power transmission, thereby further improving the consistency of adjustment at both ends of the sunshade 130 and the smoothness of operation.

[0043] More preferably, the cross-section of the transmission hole 212 is a regular polygon. For example, the cross-section of the transmission hole 212 can be set as a regular square, a regular hexagon, a regular octagon, etc., without specific limitations.

[0044] Of course, in other feasible embodiments, the designer can adjust the torque transmission structure between the output gear 211 and the connecting rod 221 according to the needs of use. For example, a torque transmission key is provided between the output gear 211 and the connecting rod 221. No specific restrictions are made here.

[0045] In the embodiments of this utility model, such as Figure 3 In the embodiment shown, the drive device 230 includes a drive motor and a reduction gear 240 that is tractably connected to the drive motor. The drive motor is tractably connected to the output gear 211 through the reduction gear 240.

[0046] The reduction structure 240 reduces the output power of the drive unit 230 by increasing torque, thereby improving the torque output capability and operational smoothness of the output gear 211 during the driving process. This better meets the dual requirements of the sunshade assembly for driving force and speed control. Furthermore, the reduction structure 240 helps reduce the load pressure on the drive unit 230, extending its service life.

[0047] In one specific embodiment, the output gear 211 and the reduction structure 240 cooperate to form a reducer, and the shaft of the drive motor is parallel to the axis of the transmission hole 212. By cooperating with the reducer, the power output efficiency is improved, and the structure is better integrated, reducing space occupation.

[0048] Furthermore, by aligning the drive motor shaft with the axis of the transmission hole 212, the off-center load and vibration during transmission are reduced, minimizing the risk of vibration and abnormal noise, thereby improving the smoothness and quietness of the sunshade assembly.

[0049] In the embodiments of this utility model, such as Figure 1 and Figure 2 In the embodiment shown, the synchronization adjustment mechanism 140 includes two synchronous belts 141 respectively disposed on two guide rails 111, and two front synchronous pulleys 142 respectively disposed on the first front bracket 112 and the second front bracket 113. Each front synchronous pulley 142 is tractably connected to a synchronous belt 141. The two synchronous belts 141 are respectively connected to the two ends of the pull rod 120. The front synchronous pulley 142 is provided with a transmission insertion hole, and the connector 220 can be inserted into the transmission insertion hole.

[0050] Specifically, both ends of the pull rod 120 are equipped with sliders, which are slidably mounted in the guide rail 111, thereby improving the smoothness of the sliding of the pull rod 120. Through the cooperation of the synchronous belt 141 and the front synchronous pulley 142, the synchronous drive of both ends of the pull rod 120 is realized, effectively ensuring the consistency and stability of the operation of the sunshade 130 during the unfolding or retraction process, and avoiding the skewing or jamming caused by asynchronous transmission.

[0051] Furthermore, the connector 220 can rigidly connect to the front synchronous pulley 142, ensuring the synchronization of the transmission. The detachable plug-in connection between the connector 220 and the front synchronous pulley 142 also improves the installation efficiency and maintenance convenience.

[0052] The drive unit 230 outputs torque through the reduction structure 240 in the reducer, and transmits the torque to the connecting rod 221 through the output gear 211. The connecting rod 221 can drive the two front synchronous pulleys 142 to rotate synchronously, thereby realizing synchronous transmission. Through the cooperation of the synchronous belt 141, the front synchronous pulleys 142 and the drive unit 230, the rotation of the drive motor can be converted into the movement of the pull rod 120 in the X direction (the length direction of the vehicle), thereby driving the sunshade 130 to open or close.

[0053] In the embodiments of this utility model, such as Figure 1 , Figure 6 and Figure 7 In the embodiment shown, the synchronization adjustment mechanism 140 includes two front synchronization wheels 142. The first front bracket 112 is provided with two spaced-apart first support portions 1121. The first support portions 1121 are provided with first slots. The openings of the first slots are arranged opposite to the guide rail 111. The two ends of one front synchronization wheel 142 are respectively engaged in the two first slots. And / or, the second front bracket 113 is provided with two spaced-apart second support portions 1131. The second support portions 1131 are provided with second slots. The openings of the second slots are arranged opposite to the guide rail 111. The two ends of another front synchronization wheel 142 are respectively engaged in the two second slots.

[0054] Preferably, the synchronization adjustment mechanism 140 includes two front synchronization wheels 142. The first front bracket 112 is provided with two spaced-apart first support parts 1121. The first support parts 1121 are provided with first slots. The openings of the first slots are arranged opposite to the guide rail 111. The two ends of one front synchronization wheel 142 are respectively engaged in the two first slots. The second front bracket 113 is provided with two spaced-apart second support parts 1131. The second support parts 1131 are provided with second slots. The openings of the second slots are arranged opposite to the guide rail 111. The two ends of another front synchronization wheel 142 are respectively engaged in the two second slots.

[0055] Specifically, two first support parts 1121 are arranged at intervals along a direction perpendicular to the guide rail 111, and two second support parts 1131 are arranged at intervals along a direction perpendicular to the guide rail 111. By using the first and second slots to limit and support the two ends of the two front synchronous pulleys 142 respectively, the stability of the front synchronous pulleys 142 during transmission is effectively improved, and the transmission error caused by the swaying or offset of the front synchronous pulleys 142 is reduced, further ensuring the smooth operation and reliability of the sunshade assembly.

[0056] Furthermore, the two first support parts 1121 can limit the synchronous pulley in the Y direction (vehicle width direction), preventing the synchronous pulley from moving or slipping out in the Y direction. The snap-fit ​​structure also facilitates quick installation or removal of the front synchronous pulley 142, improving the installation efficiency and maintenance convenience of the front synchronous pulley 142.

[0057] In an embodiment of this utility model, the sunshade assembly further includes a winding mechanism disposed between two guide rails 111, and the sunshade 130 is adjustablely disposed between the pull rod 120 and the winding mechanism.

[0058] The orderly rolling and unfolding of the sunshade 130 is achieved through a winding mechanism, effectively improving the flatness and aesthetics of the sunshade 130 during use. Designers can adjust the specific structure of the winding mechanism according to usage needs, and no specific restrictions are imposed here.

[0059] Furthermore, by arranging the drive motor on the side away from the winding mechanism and fixing the drive motor to the front fixed base, the drive motor can drive the connecting rod 221 to rotate, and at the same time drive the two front synchronous pulleys 142. Then, through the synchronous belt 141, the two ends of the pull rod 120 are synchronously transmitted, driving the sunshade curtain 130 to move forward or backward, thereby flexibly adjusting the position of the sunshade curtain 130.

[0060] Furthermore, the synchronization adjustment mechanism 140 also includes two rear synchronous pulleys mounted on the guide rail frame structure 110, with a synchronous belt 141 positioned between the corresponding front synchronous pulley 142 and the rear synchronous pulleys. Through the cooperation of the two rear synchronous pulleys and the two front synchronous pulleys 142, the synchronous belt 141 can be driven to move, thereby causing the pull rod 120 to adjust the position of the sunshade 130. Designers can adjust the specific arrangement of the rear synchronous pulleys according to usage needs; no specific limitations are imposed here.

[0061] Of course, in other feasible embodiments, designers may also use pulleys and drive lines instead of timing pulleys and timing belts 141, without making specific limitations here.

[0064] By installing a sunshade assembly on the glass to form a glass assembly, the light transmission effect of the glass assembly can be flexibly adjusted, improving user comfort.

[0065] In a preferred embodiment, the guide rail 111 of the glass assembly is arranged along the length direction of the vehicle body, and the connector 220 of the glass assembly is arranged along the width direction of the vehicle body.
