Description

Technical Field

[0001] This utility model relates to an electric sunshade assembly for a motor vehicle sunroof, belonging to the technical field of electric sunshade technology. Background Technology

[0002] The electric sunshade assembly is an indispensable and important component of the vehicle sunroof system. It integrates functions such as sunshade, heat insulation, and convenient operation, creating a comfortable in-vehicle environment for car owners.

[0003] Traditional motorized sunshade assemblies still have the following technical problems, based on practical experience: The transmission mechanism is susceptible to contamination, wear, and abnormal noise: Dust, sand, and other impurities easily accumulate in the transmission components, leading to accelerated wear, noise, and even premature failure.

[0004] The problem of asynchronous operation and easy deviation and jamming of the sunshade curtain: Due to manufacturing errors, assembly gaps or uneven friction resistance, the sliders on the left and right sides move asynchronously, which will cause the curtain to be skewed (deviation) and eventually get stuck on one side, making it unable to open and close normally.

[0005] Reliability and durability issues arising from the servo drive system: In some designs, power devices such as motors may be directly mounted on moving parts or move with them, which can lead to frequent bending of the motor wiring harness, increasing the risk of line fatigue, short circuits and failures.

[0006] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0007] This utility model addresses the shortcomings of the prior art by providing an electric sunshade assembly for motor vehicle sunroofs. It systematically solves the problems of existing electric sunshades in terms of environmental adaptability, synchronization, and durability, and significantly improves the overall performance and user experience of the product.

[0008] To solve the above technical problems, the present invention adopts the following technical solution: An electric sunshade assembly for a motor vehicle sunroof includes two symmetrically arranged slide rails. A rear beam, perpendicular to the rear ends of each slide rail, is located above its rear end. Both ends of the rear beam are connected to the ends of the slide rails via roller blind brackets. A roller blind assembly is installed between the two roller blind brackets. The roller blind assembly includes a curtain fabric. A support beam is fixedly installed at one end of the curtain fabric. Slider blocks that move along the slide rails are fastened to both ends of the support beam along its length. Open grooves are provided on the opposing inner sides of both slide rails, and closed grooves are provided inside the slide rails along their length.

[0009] Furthermore, the front ends of the two slide rails are equipped with front beams that are perpendicular to them, and the front beams have a Z-shaped structure.

[0010] Furthermore, the other end of the curtain is fixed and wound around a roller, which is rotatably mounted between two roller blind brackets.

[0011] Furthermore, the support beam has rectangular snap-fit ​​grooves at both ends along its length, and the slider has snap-fit ​​protrusions that cooperate with the snap-fit ​​grooves.

[0012] Furthermore, the slide rail is made of aluminum profile.

[0013] Furthermore, a fixing seat is installed in the middle of the rear beam, a power unit is installed on one side of the fixing seat, and a tube body fixator is installed on the other side.

[0014] Furthermore, the power unit consists of a motor and a controller, and a gear is mounted on the output shaft of the power unit.

[0015] Furthermore, two tubes are respectively installed on the left and right sides behind the rear beam.

[0016] Furthermore, one end of the tube is clamped and fixed between the fixing seat and the tube holder, and the other end of the tube is fixedly installed in the end of the slide rail by a pressure plate. The two tubes are respectively connected to the open slide groove and the closed slide groove of the slide rail.

[0017] Furthermore, two flexible shafts are installed between the fixed base and the tube body fixer. The two flexible shafts are distributed on both sides of the gear, and one end of the flexible shaft passes through the tube body and is connected to the slider.

[0018] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages: The copper tube serves as a guide and protective sleeve for the flexible shaft. One end of the copper tube is connected to the sealed groove of the slide rail, and the other end is fixed between the fixed seat and the tube holder, forming a complete closed channel from the power source to the actuator. This avoids noise caused by impurities entering or parts becoming loose, effectively isolates external dust, moisture and impurities, and adapts to the harsh environment on the roof. The single motor synchronously drives the flexible shafts symmetrically arranged on both sides for transmission, ensuring that both ends of the support beam always move at the same time and speed, effectively preventing the curtain from running off-center, twisting or jamming, and making the operation more stable and reliable. The power unit and complex transmission system are centrally mounted on a fixed rear beam, so the power system does not move with the sunshade, which greatly improves the reliability and durability of the system.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation

[0022] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0023] like Figures 1-3 As shown in the figure, this utility model provides an electric sunshade assembly for a motor vehicle sunroof, including two slide rails 2 arranged symmetrically on the left and right. A front beam 1 is installed at the front end of the two slide rails 2 and is arranged perpendicularly thereto. A rear beam 3 is provided above the rear end of the two slide rails 2 and is arranged perpendicularly thereto. The two ends of the rear beam 3 along the length direction are respectively connected to the ends of the slide rails 2 through a roller blind bracket 4.

[0024] A roller blind assembly 5 is installed between two roller blind brackets 4. The roller blind assembly 5 includes a curtain 51. One end of the curtain 51 is fixed and wound around a roller shaft 52. The roller shaft 52 is rotatably installed between the two roller blind brackets 4. A support beam 53 is fixedly installed on the other end of the curtain 51. The two ends of the support beam 53 along the length direction are respectively fastened to sliders 54 that move along the slide rail 2.

[0025] The support beam 53 has rectangular snap-fit ​​grooves at both ends along its length, and the slider 54 has snap-fit ​​protrusions that cooperate with the snap-fit ​​grooves.

[0026] The slide rail 2 is made of aluminum profile. Both slide rails 2 have open slide grooves 21 on their opposing inner sides. The open slide grooves 21 are used for the movement of the slider 54. The slide rail 2 has a closed slide groove 22 inside along its length.

[0027] A fixed seat 6 is installed in the middle of the rear beam 3. A power unit 7 is installed on one side of the fixed seat 6, and a tube body fixator 8 is installed on the other side. The power unit 7 consists of a motor and a controller, and a gear is installed on the output shaft of the power unit 7. The power unit 7 provides power for the support beam 53 and the slider 54 to move along the slide rail 2, thereby driving the curtain 51 to open or close.

[0028] Two tubes 9 are respectively installed on the left and right sides behind the rear beam 3. The tubes 9 are made of copper tubes. The inner cavity of the tubes 9 is used for the insertion of the flexible shaft. The function of the tubes 9 is to serve as guides and protective sleeves for the flexible shaft.

[0029] One end of the tube body 9 is clamped and fixed between the fixing seat 6 and the tube body fixing device 8, and the other end of the tube body 9 is fixedly installed in the end of the slide rail 2 through the pressure plate 10. The two tube bodies 9 are respectively connected to the open slide groove 21 and the closed slide groove 22 of the slide rail 2.

[0030] Two flexible shafts are installed between the fixed base 6 and the tube body fixator 8. The two flexible shafts are distributed on both sides of the gear, and one end of the flexible shaft passes through the tube body 9 and is connected to the slider 54. The two flexible shafts symmetrically pull the left and right sliders 54 to move.

[0031] The front beam 1 has a Z-shaped structure to facilitate installation.

[0032] The specific working principle of this utility model is as follows: The controller receives commands from the sunroof switch of the vehicle or directly from the user to control the forward and reverse rotation of the motor. The motor drives two flexible shafts enclosed in a tube to move by rotating the output gear. The flexible shafts then drive the slider connected to the sunshade curtain to slide in the slide rail, thereby realizing the unfolding and retraction of the curtain.

[0033] The power unit and complex transmission mechanism in this invention are fixed at the rear and do not move with the sunshade, thus improving reliability and durability. The double flexible shaft design ensures synchronous movement at both ends of the support beam, preventing the curtain from slipping or jamming. The fully enclosed guide rail, with its sealed grooves and copper tubing, protects the flexible shaft and slider, providing dustproof, waterproof, and noise-proof protection, making it suitable for the harsh working environment of motor vehicles.
