Abstract
Description
Technical Field
[0001] This invention belongs to the technical field of automotive parts, and particularly relates to a telescopic sunshade used for automotive windows.
Background Art
[0002] In the high-temperature environment in summer, in some vehicle models, there is a problem that the shading performance inside the vehicle is not sufficient, so the temperature inside the vehicle rises excessively. Therefore, in recent years, as a means to compensate for the insufficient shading performance inside the vehicle, telescopic sunshades have attracted attention as a new shading solution for vehicle windows.
[0003] For example, a Chinese patent published with the publication number CN101537782B discloses an automotive sunshade. The sunshade includes a sunshade base, a sunshade body, and a hook. The sunshade is positioned by the sunshade base and is configured to be wound inside it. The outer end of the sunshade is a pull-out end, and the pull-out end can appear and disappear by a pull-out operation or elastic return. A rod member penetrates through the pull-out end, and the rod member is rotatably connected to the hook. When in use, the bottom surface of the sunshade base is fixed to the upper surface of the inner lining of the vehicle door and is configured to be attached by a double-sided tape or a hook fastener. When the sunlight is strong, by pulling out the curtain from the sunshade base and fixing it with a hook, the shading effect inside the vehicle can be improved.
[0004] However, for the sunshade as described above, since the sunshade base has an integral structure, it is difficult to remove when fixed with a double-sided tape, and when fixed with a hook fastener, one side of the hook fastener remains on the upper surface of the inner lining of the vehicle door after removal, which has the problem of damaging the appearance and comfort. Therefore, it is difficult to achieve both convenience in attachment and detachment and aesthetics and comfort after removal.

Modes for Carrying Out the Invention
[0022] The present invention will be described in more detail below based on Figures 1 to 7 and the embodiments.
[0023] (Example 1) This embodiment relates to a retractable sunshade applied to an automobile window. Referring to Figures 1 to 4, the retractable sunshade includes a base body 1, a screen 2, and a hook 3. The base body 1 includes a main body 4, an upper base 5, and a lower base 6. The screen 2 is rolled up and stored within the main body 4, and the hook 3 is provided at the end of the roll screen 2 when it is pulled out.
[0024] The upper base 5 is fixed to the end of the main body 4, and the lower base 6 is attached to the interior trim of the vehicle door.
[0025] Furthermore, a quick-release structure is provided between the upper base 5 and the lower base 6. The device is configured with two upper bases 5 and two lower bases 6. The two upper bases 5 are fixed to both the left and right ends of the main body 4, and the lower bases 6 are adhesively fixed to both the left and right sides of the upper surface of the vehicle door trim.
[0026] According to the above configuration, when the retractable sunshade is installed on the vehicle door trim, the adhesive (double-sided adhesive tape in this embodiment) interposed between the lower base 6 and the vehicle door trim ensures a stable installation of the retractable sunshade. On the other hand, if it becomes necessary to remove the retractable sunshade from the vehicle door trim, the quick-release structure provided between the upper base 5 and the lower base 6 allows for easy removal of the retractable sunshade. Furthermore, since only the lower base 6 remains on the vehicle door trim, a good appearance and comfort can be maintained even after the sunshade is removed.
[0027] The shape of the lower base 6 is designed according to the shape of the vehicle door trim, and the lower base 6 is configured to be stably attached to both the left and right sides of the upper surface of the vehicle door trim using double-sided adhesive tape. In this embodiment, when the retractable sunshade is installed on the rear door of a car, the two lower bases 6 are configured to have a "7" shape facing each other.
[0028] In this embodiment, the main body 4 includes a tubular body which is hollow and communicates with the left and right sides. Furthermore, the tubular body of the main body 4 has a slit 41 that extends axially along the side facing the vehicle window, allowing the screen 2 to expand and contract. In addition, the upper base 5 has a housing groove 51 on the surface facing the tubular body of the main body 4, and when the upper base 5 is fixedly connected to the main body 4, the end of the tubular body of the main body 4 is inserted into the recess 51. The tubular body of the main body 4 tends to expand radially outward due to the formation of the slit 41, which allows the tubular body to press against the upper base 5 and improve the stability of the connection between the two.
[0029] Furthermore, in this embodiment, the upper base 5 and the lower base 6 are connected by magnetic force. Specifically, the quick-release structure provided between the upper base 5 and the lower base 6 includes a first magnet 71 and a second magnet 72, with the first magnet 71 provided at the bottom of the upper base 5 and the second magnet 72 provided at the top of the lower base 6. When the upper base 5 is placed on the lower base 6, the first magnet 71 and the second magnet 72 are positioned with opposite polarities, and the upper base 5 and the lower base 6 are detachably connected by the magnetic force of the first magnet 71 and the second magnet 72. Furthermore, when removal is necessary, it can be quickly removed by applying a certain external force, thus realizing rapid attachment and detachment through the quick-release structure. Furthermore, a first fitting groove 81 is formed at the bottom of the upper base 5, and the first magnet 71 is fitted into the first fitting groove 81. A screw hole is formed between the first fitting groove 81 and the first magnet 71, and the first magnet 71 is fixed to the upper base 5 by a screw 52 through the screw hole, thereby improving the mounting stability of the first magnet 71 to the upper base 5. A second fitting groove 82 is formed at the top of the lower base 6, and the second fitting groove 82 has a shape that is smaller at the top and larger at the bottom, and is formed to penetrate both the left and right sides of the upper part of the lower base 6. As a result, the second magnet 72 is fitted and positioned from both the left and right sides of the upper part of the lower base 6, and its position is restricted in the vertical direction. As a result, the ease of mounting the second magnet 72 is ensured, and the stability after mounting is improved.
[0030] In this embodiment, a mesh material is used for the sunshade. The mesh material is relatively lightweight and flexible, making it easy to install and store. Furthermore, compared to conventional thick fabrics, a sunshade made of mesh material is lightweight and expands and contracts smoothly, preventing it from excessively occupying the interior space of the vehicle. In addition, in other embodiments, a fabric material can be used as the sunshade. Fabric materials have high light-blocking properties, and in addition to providing a light-blocking effect, they can protect privacy inside the vehicle and prevent outside views.
[0031] (Example 2) This embodiment also relates to a retractable sunshade applied to an automobile window. Referring to Figures 5 and 6, this embodiment differs from Embodiment 1 in the following respects. In this embodiment, both the upper base 5 and the lower base 6 are made of resin; specifically, the upper base 5 and the lower base 6 are formed of polyurethane resin and have good elasticity. Furthermore, a locking portion 91 and a locking groove 92 are provided between the upper base 5 and the lower base 6. The locking portion 91 is provided on the side surface of the upper base 5, and the locking groove 92 is provided on the side surface of the lower base 6, and when the upper base 5 and the lower base 6 are connected, the locking portion 91 engages with the locking groove 92. In addition, a guide portion 93 is formed on the side surface of the upper base 5, and a guide groove 94 is formed between the top surface and the side surface of the lower base 6, into which the guide portion 93 slides. By providing the guide portion 93 and the guide groove 94, the positioning accuracy during assembly of the upper base 5 and the lower base 6 is improved, thereby improving assembly workability and mounting efficiency.
[0032] (Example 3) This embodiment also relates to a retractable sunshade applied to an automobile window. Referring to Figure 7, this embodiment differs from Embodiment 2 in the following respects. In this embodiment, the locking groove 92 is formed on the side surface of the upper base 5, and the locking portion 91 is provided on the side surface of the lower base 6. Furthermore, the locking portion 91 itself functions as a guide portion 93, and a guide groove 94 with a bottom opening is formed on the edge of the locking groove 92, with the bottom of the guide groove 94 receiving the insertion of the guide portion 93. This configuration improves the positioning accuracy when assembling the upper base 5 and the lower base 6, thereby improving assembly workability and mounting efficiency.
