Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0020] The purpose of this utility model is to provide a front pull plate structure for an electric sunshade for vehicles, so as to solve the problems existing in the prior art, reduce light leakage and uneven light emission, improve the accuracy of light guide alignment, optimize the lead wire layout, and reduce the difficulty of construction and assembly.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1 This embodiment provides a front pull panel structure for an electric sunshade in a vehicle, such as... Figures 1-3 As shown, it includes: a front pull plate 1, which includes a pull plate profile 11 and a fastening member 12; the fastening member 12 can be fixedly mounted on the pull plate profile 11, and at least a portion of the sidewall of the pull plate profile 11 and at least a portion of the sidewall of the fastening member 12 can form an opaque sealed space; the pressing surface 1221 of the fastening member 12 and the receiving surface 1121 of the pull plate profile 11 are used to fix and press the front end of the curtain fabric 3, and expose the light guide portion on the front end face of the curtain fabric 3; a light source module 2, which is fixed in the sealed space, and the orthogonal light from the light source module 2 is used to contact the front end face of the curtain fabric 3. The exposed light guide section (the light guide mesh layer built into the curtain 3 is composed of multiple light guide filaments and multiple support yarns interwoven together. The light guide mesh layer and the light guide points on the front end face of the curtain 3 together constitute the light guide section, and the ends of the light guide filaments form light guide points) are opposite; the lead wire 21 is electrically connected to the light source module 2 at one end and extends to the rear end of the curtain 3 at the other end, and is electrically connected to the branch wire harness (the branch wire harness is a branch of the circuit lead control system 5, and the circuit lead control system 5 is the original power supply control module of the car sunshade) at the rear roll-up shaft 4 of the curtain 3.

[0023] By setting a front pull plate 1 composed of a pull plate profile 11 and a fastening member 12 (the length of the front pull plate 1 is consistent with the width direction of the curtain fabric 3), a light-blocking sealed space is formed by a portion of the side wall of the pull plate profile 11 and a portion of the side wall of the fastening member 12. This achieves both sealing and protection of the light source module 2 (specifically, the circumferential sealing of the sealed space, with the two ends of the sealed space sealed by corresponding sliders), preventing light source leakage, and reducing the impact of the external environment on the light source module 2, thus improving the working stability of the light source module 2. At the same time, the fastening member 12, through its pressing surface 1221 and the receiving surface 1121 of the pull plate profile 11, achieves fixed pressing of the front end of the curtain fabric 3. This fixing method ensures the stability of the curtain fabric 3 installation and accurately exposes the light guide part on the front end face of the curtain fabric 3. Combined with this, the light source module 2 is fixed in the aforementioned sealed space. Furthermore, by aligning the orthogonal light from the light source module 2 with the light guide exposed on the front end face of the curtain 3, the alignment accuracy between the light source module 2 and the light guide of the curtain 3 is effectively improved, avoiding light leakage and uneven light emission. In addition, by electrically connecting one end of the lead wire 21 to the light source module 2 and extending the other end to the rear end of the curtain 3 and electrically connecting it to the branch harness used for power supply and control at the rear roll-up shaft 4 of the curtain 3, the layout of the lead wire 21 of the light source module 2 is optimized, simplifying the connection process between the light source module 2 and the power supply and control harness. This eliminates the need for additional complex connection structures, reduces construction difficulty and assembly time, and avoids malfunctions caused by messy wiring. At the same time, the front pull plate 1 only includes the pull plate profile 11 and the fastening part 12, simplifying the number of parts required for the installation of the light source module 2 and reducing the space occupied by the installation structure, ultimately achieving a balance between practical function and decorative effect.

[0024] The following are the relevant settings for the pull plate profile 11: Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 and Figure 3 As shown, the end of the pull plate profile 11 closest to the rear roll-up shaft 4 of the curtain fabric 3 is the front end (i.e., Figure 1 The leftmost end of the pull plate profile 11, and the end of the pull plate profile 11 furthest from the rear winding shaft 4 of the curtain fabric 3 is the rear end (opposite to the front end); the front end of the curtain fabric 3 is used to successively pass over the bottom of the front end, the bottom of the rear end, and the top of the rear end, and is then fixedly pressed by the pressing surface 1221 and the receiving surface 1121 (e.g. Figure 1 As shown, the curtain fabric 3 is tightly attached to the outer wall and part of the inner wall of the pull plate profile 11. The corners of the hook protrusions 112 are rounded to avoid scratching the curtain fabric 3 and to help the fasteners 12 tighten the curtain fabric 3 during installation. The front end of the curtain fabric 3 is attached to the bottom of the front end and the bottom of the rear end of the pull plate profile 11 in sequence, and then around the top of the rear end before being fixed by the pressing surface 1221 and the receiving surface 1121. This increases the contact area between the curtain fabric 3 and the pull plate profile 11 and improves the stability of the installation.

[0025] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 and Figure 3 As shown, the pull plate profile 11 includes a base 111 and a hook protrusion 112 fixedly connected together (specifically, the base 111 and the hook protrusion 112 are integrally formed parts). The free end of the hook protrusion 112 is bent towards the side closer to the base 111. The cavity groove 1111 of the base 111 and part of the inner wall of the clamping member 12 can jointly form a sealed space. The cavity groove 1111 and the side wall opposite to the hook protrusion 112 are provided with slots 1112. One end of the clamping member 12 is used to be inserted into the slot 1112, and the other end has a head protrusion 122. The lower end face of the head protrusion 122 forms a pressing surface 1221, and the inner bottom surface of the hook protrusion 112 forms a receiving surface 1121. The side wall of the head protrusion 122 away from the slot 1112 and the inner side wall of the hook protrusion 112 are fixedly pressed against the curtain fabric 3 (e.g., ...) at that position. Figure 1 (As shown). The cavity groove 1111 of the substrate 111 and the inner wall of the fastening member 12 together form a sealed space, which provides stable protection for the light source module 2 and ensures the light-shielding effect. The pressing surface 1221 and the receiving surface 1121 press against the curtain 3, and the pressing between the side wall of the head protrusion 122 away from the slot 1112 and the inner side wall of the hook protrusion 112 against the corresponding position of the curtain 3, the double fixing structure improves the reliability of the curtain 3 installation and avoids displacement during opening and closing. Moreover, the pressing surface 1221 and the receiving surface 1121 ensure that the light guide material exposed on the front end face of the curtain 3 is accurately aligned with the light source module 2, ensuring uniform and stable light emission.

[0026] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 and Figure 3 As shown, the hook protrusion 112 has a weight-reducing cavity 1122 inside (the weight-reducing cavity 1122 is opened along the length of the hook protrusion 112). While ensuring its structural strength to stably support the pressing and fixing of the curtain fabric 3 and to form a sealed space, it can effectively reduce the overall weight of the front pull plate 1, reduce the load on the curtain fabric 3 when it is pulled up and down, improve the smoothness of operation, and at the same time reduce the amount of material used, taking into account both practicality and economy.

[0027] The following are the relevant settings for the clamping component 12: Specifically, one end of the clamping member 12 is used to be inserted into the slot 1112, and the other end has a head protrusion 122; the lower end surface of the head protrusion 122 forms a pressing surface 1221.

[0028] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 and Figure 3As shown, the clamping member 12 is inserted into a flat plate 121 at one end of the slot 1112; in the vertical direction, the inner height of the slot 1112 is greater than the thickness of the flat plate 121 in the same direction; the upper wall of the slot 1112 near the hook protrusion 112 is fixed with an abutting lower edge 1113 for contacting the upper surface of the flat plate 121. The interference fit between the head protrusion 122 of the clamping member 12 and the hook protrusion 112, and the abutting contact between the abutting lower edge 1113 and the flat plate 121 of the clamping member 12, together constrain and limit the clamping member 12, ensuring a stable connection between the clamping member 12 and the pull plate profile 11.

[0029] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 and Figure 3 As shown, an arc-shaped groove 1222 is provided between the lower end face of the head protrusion 122 and the side wall. A cylindrical retaining rod 13 is provided in the arc-shaped groove 1222, and the cylindrical retaining rod 13 corresponds to the inner angle of the hook protrusion 112. The arc-shaped groove 1222 enables the stable installation and positioning of the cylindrical retaining rod 13. At the same time, the fitting and contact between the cylindrical retaining rod 13 and the inner angle of the hook protrusion 112 provides a guiding effect for the head protrusion 122 of the clamping part 12 to be smoothly pressed into the inner side of the hook protrusion 112, thereby reducing assembly resistance.

[0030] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 As shown, the side wall of the head protrusion 122 away from the slot 1112 and the inner side wall of the hook protrusion 112 are interference fit (e.g., Figure 1 As shown, the interference fit here refers to the locking and fixing of the curtain 3 through the pressure of the contact surface, which serves to lock the fabric and steel wire, prevent the curtain 3 from shaking or falling off, and at the same time ensure the airtightness of the sealed space.

[0031] The following are the settings instructions for light source module 2: Among the optional solutions in this embodiment, the more preferred one is as follows: Figures 1-3 As shown, lead wire 21 is close to the side binding strip of the curtain 3 (the curtain 3 is provided with binding strips on both sides) and fixed (specifically, fixed setting; the same applies to other positions in the text, and will not be explained further) to the upper surface of the curtain 3; the lead wire extends backward along the side of the curtain 3 and is electrically connected to the conductive slip ring at the rear winding shaft 4 of the curtain 3 (a conductive slip ring that can rotate along the axis of the rear winding shaft 4 is provided in the middle of the branch wire harness to avoid damage to the power supply wire harness when the rear winding shaft 4 rotates).

[0032] Specifically, lead wire 21 extends from the end of front pull plate 1 along the side of light guide curtain 3 and close to the edge band, to the rear take-up shaft 4, then through the slot on the rear take-up shaft 4, into the interior of the tube of the rear take-up shaft 4, and through the center hole of the plastic part at the end of the rear take-up shaft 4, extends to the rear crossbeam 6 and connects to the circuit lead wire control system 5.

[0033] In the optional solutions of this embodiment, it is more preferred that the light source module 2 is a strip light source (the strip light source is composed of a flexible circuit board and multiple LED beads fixedly mounted on the flexible circuit board). The light source module 2 is set as a strip light source, which can be adapted to the sealed space for installation, increase the light emission coverage, and make the light uniformly projected onto the light guide material exposed at the front end face of the curtain 3, thereby improving the uniformity of light emission and avoiding local differences in brightness.

[0034] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 and Figure 3 As shown, the light source module 2 is bonded and fixed to the inner wall of the clamping member 12 within the sealed space. Bonding and fixing the light source module 2 to the inner wall of the clamping member 12 within the sealed space eliminates the need for additional clips or bolts, simplifying assembly parts and processes. It also avoids occupying internal space within the sealed space, ensuring the alignment accuracy of the light source's orthogonal beam and the light guide, further guaranteeing the opacity of the sealed space, preventing light source leakage, and balancing structural compactness with operational stability.

[0035] Regarding other relevant explanations: Specifically, since the front pull plate 1 consists only of the pull plate profile 11 and the fastening member 12, and the fastening member 12 is connected to the pull plate profile 11 by insertion and pressing, it can be quickly disassembled without tools. When the light source module 2 malfunctions, the light source module 2 can be removed and replaced simply by removing the fastening member 12. Compared with the maintenance method in the prior art that requires the disassembly of multiple auxiliary parts, the maintenance efficiency is greatly improved.

[0036] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
