Description

Technical Field

[0001] The present invention relates to the field of vehicle sunshade devices, and particularly to a front windshield sunshade assembly for an automobile. Background Art

[0002] With the popularization of automobiles and the increasing requirements for driving comfort, the quality of the in-vehicle environment has gradually become the focus of attention. In summer or in an environment with strong sunlight, long-term exposure of the vehicle to sunlight will cause a sharp increase in the in-vehicle temperature, which not only affects driving comfort, but may also cause damage such as aging and fading of interior materials. In addition, strong ultraviolet radiation will also have an adverse impact on the skin health of the driver and passengers. Therefore, how to effectively block sunlight, reduce the in-vehicle temperature and protect the interior has become an important issue in the field of automotive supplies.

[0003] Traditional automobile sunshade methods mainly include using sunshades, sunshades or sun umbrellas, etc. Although these methods can block sunlight to a certain extent, there are many deficiencies. For example, a sunshade usually needs to be manually placed inside the front windshield, and the installation and disassembly are relatively cumbersome, and the shading area is limited; although a sunshade can cover a larger area, the fixing method is not stable enough and is easy to shake or fall off in windy weather; a sun umbrella is limited by its structure and size, cannot completely cover the front windshield, and is inconvenient to store. In addition, the materials and designs of traditional sunshade tools often cannot effectively reflect sunlight and block ultraviolet rays, and the sunshade effect is limited.

[0004] Therefore, it is very necessary to invent a front windshield sunshade assembly for an automobile. Summary of the Invention

[0005] The purpose of the present invention is to provide a front windshield sunshade assembly for an automobile to solve the problems that the existing vehicle sunshade structure still has a cumbersome installation and disassembly process, limited sunshade area and sunshade degree, and unstable installation.

[0006] To achieve the above purpose, the present invention provides the following technical solutions: including a mounting plate spring box, a support structure, a guiding cable, a hood hook, a sunshade structure and a rearview mirror fixing structure, and the mounting plate spring box is fixedly installed at both ends of the vehicle body roof surface, and the support structure is fixedly installed between two groups of mounting plate spring boxes; the guiding cable is wound inside the mounting plate spring box, and the hood hook is fixedly installed at the top end of the guiding cable and is hung inside the gap at the front end of the vehicle body hood; the sunshade structure is slidably installed on the guiding cable, and the rearview mirror fixing structure is fixedly installed on the outside of the front end of the sunshade structure and is sleeved on the rearview mirror of the vehicle body.

[0007] The support structure includes a support rod, an upper elastic band, a male end buckle, a lower magnetic band and a female end buckle. The support rod is fixedly installed between two groups of mounting plate spring boxes, and the upper elastic band is fixedly installed on the upper sides of both ends of the support rod; the lower magnetic band is fixedly installed on the lower sides of both ends of the support rod; the male end buckle is fixedly installed at one end of the upper elastic band, and the female end buckle is fixedly installed at one end of the lower magnetic band. The male end buckle and the female end buckle are snap-connected.

[0008] The guiding cable includes a guiding steel cable, connecting sections, expanding sections and a sliding layer. The connecting sections and the expanding sections are alternately and fixedly installed on the surface of the guiding steel cable, and the sliding layer wraps around the outside of the connecting sections and the expanding sections.

[0009] The hood hook includes a support rope head, a guiding ring, a fixed hook and a protective rubber sleeve. The support rope head is fixedly installed at one end of the guiding cable, and the guiding ring is rotatably installed at the front end of the support rope head; the fixed hook is rotatably installed at the front end of the guiding ring, and the protective rubber sleeve is fixedly installed on the outside of the fixed hook.

[0010] The sunshade structure includes a sunshade cloth piece, an upper end extension piece with a fixed magnetic strip, a lower end extension piece, a through rope hole and a reinforced edge. The front end extension piece is sewn on the upper end of the sunshade cloth piece, and the fixed magnetic strip is fixedly installed inside the upper end extension piece; the lower end extension piece is sewn on the lower end of the sunshade cloth piece, and rearview mirror fixing structures are fixedly installed at both ends of the lower end extension piece. The through rope hole is opened inside the sunshade cloth piece, and the guiding cable passes through it; the reinforced edge is sewn on the outside of the sunshade cloth piece;

[0011] The sunshade cloth piece includes a reflective layer, a radiation layer, a heat insulation layer and an evaporation layer. The radiation layer is adhesively fixed to the bottom of the reflective layer, and the heat insulation layer is adhesively fixed to the bottom of the radiation layer; the evaporation layer is adhesively fixed to the bottom of the heat insulation layer.

[0012] The rearview mirror fixing structure includes a connecting piece, a connecting buckle, an elastic strip, an elastic ring and a tightening hoop. The connecting piece is sewn at both ends of the lower end extension piece, and the elastic strip is connected to the connecting piece through the connecting buckle; the elastic ring is fixedly installed at one end of the elastic strip, and the tightening hoop is slidably installed on the outside of the elastic strip and the elastic ring.

[0013] The support rod inside the support structure is a bendable rubber rod-shaped structure. The support rod can connect two groups of mounting plate spring boxes together. After the mounting plate spring boxes are installed on the arc-shaped car roof, it can match this arc through its own bending; the upper elastic band and the lower magnetic band can be connected at the head end through the male end buckle and the female end buckle to form a circular ring, and the retracted sunshade structure can be tied inside it; flexible magnetic sheets are arranged inside the lower magnetic band, which can adsorb the car roof at any time.

[0014] The fixed hook inside the hood hook uses a flat steel metal hook, and a layer of silicone sleeve is wrapped around the outside of the fixed hook. The fixed hook can be inserted into the gap between the vehicle body and the hood. After the fixed hook is inserted into the gap, the position where its rear end contacts the hood is filled with a protective rubber sleeve. The fixed hook can be adjusted and rotated at multiple angles with the support of the guiding ring. The hood hook can make the guiding cable be placed between the roof and the hood.

[0015] The sunshade cloth piece inside the sunshade structure is provided with creases, and the sunshade cloth piece can be folded and stored through the creases. The unfolding and storage of the sunshade cloth piece are both carried out on the guiding cable. The upper end extension piece can be adsorbed on the roof after the sunshade cloth piece fixing magnetic strip is unfolded. After being stored, the sunshade structure can be tied tightly by the upper elastic band and the lower magnetic band, and is attached to the roof through the lower magnetic band.

[0016] The reflective layer inside the sunshade cloth piece uses a layer of aluminized PET, and a layer of ceramic microsphere coating is coated on the surface of the reflective layer. The radiation layer uses a thin layer made of a layer of aerogel fiber. The heat insulation layer uses a layer of closed-cell PE foam. The evaporation layer uses a layer of carbonized natural fiber moisture-absorbing material layer.

[0017] The rearview mirror fixing structure uses two groups. The elastic ring inside it uses an annular rubber structure, and the elastic ring can be sleeved on the rearview mirror. The annular size of the elastic ring can be increased or decreased by the sliding of the tightening hoop. The rearview mirror fixing structure is only used after the sunshade structure is unfolded.

[0018] The expansion section inside the guiding cable uses several sections of modified SEBS sections, and the expansion section will expand when the temperature rises to a certain temperature. The expansion of the expansion section can make the sliding layer bulge to form a gourd-shaped protrusion.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. The setting of the support structure of the present invention plays a role of connection, support and fixation. It connects two groups of mounting plate spring boxes through a bendable support rod, adapts to the roof curvature, and ensures the close fit between the sunshade assembly and the roof. At the same time, the upper elastic band and the lower magnetic band are connected by buckles to form an annular structure for fixing and storing the sunshade structure to prevent it from spreading or falling off. In addition, the support structure enhances the overall stability, disperses the force, reduces the shaking during vehicle driving, and ensures the firm fit of the sunshade assembly to the roof through the magnetic adsorption function. It is simple to operate and adapts to different vehicle models, and is the support part of the sunshade assembly.

[0021] 2. The hood hook of the present invention is provided to play a role in fixing and guiding. It is connected to the guiding cable through the supporting rope head, and the guiding cable is arranged between the vehicle roof and the hood to provide support for the sliding of the sunshade structure. The design of its guiding ring and adjustable fixed hook enables the hook to adapt to the hood gaps of different vehicle models, and at the same time, the protective rubber sleeve avoids scratching the vehicle paint. The hood hook not only enhances the stability of the sunshade component, but also makes the installation and disassembly more convenient, is applicable to various vehicle models, and is a fixed component of the sunshade component.

[0022] 3. The sunshade structure of the present invention is mainly used to block sunlight, reduce the temperature inside the vehicle and protect the interior. Its sunshade fabric is made of polyester fiber material, with a sunshade silver glue coating on both the front and back sides, effectively reflecting sunlight and reducing the entry of ultraviolet rays into the vehicle. It is slidably installed on the guiding cable through the through-rope holes. The sunshade structure can be easily unfolded or stored. When unfolded, the fixed magnetic strip of the upper extension piece adsorbs on the vehicle roof, and the lower extension piece is fixed on the rearview mirror through the rearview mirror fixing structure to ensure that the sunshade fabric tightly covers the front windshield. When stored, the sunshade fabric can be folded along the creases and fixed by the elastic band and magnetic band of the supporting structure to keep it tidy.

[0023] 4. The rearview mirror fixing structure of the present invention is connected to the lower extension piece of the sunshade structure through a connecting piece, and an elastic ring is used to sleeve on the rearview mirror of the vehicle body to ensure that the sunshade fabric can tightly fit the front windshield when unfolded, preventing the sunshade structure from shifting or loosening due to wind resistance or vehicle vibration. The elastic ring adopts an annular rubber structure, and its size can be adjusted through a tightening hoop to adapt to the rearview mirrors of different vehicle models. At the same time, the design of the elastic strip and the connecting buckle makes the installation and disassembly more convenient.

[0024] 5. The guiding cable of the present invention can be used as a track to enable the sunshade fabric to slide open and close easily. When the temperature rises, the special material in the middle of the cable will expand and thicken, automatically clamping the sunshade fabric to prevent it from being blown by the wind. Inside is a steel wire rope to ensure strength; the middle of the guiding cable is a plastic section that expands when heated, and is wrapped with an anti-abrasion layer outside. When it is hot, the plastic section expands to clamp the sunshade fabric, and when it is cool, it returns to its original state, which is both convenient to use and safe and reliable.

[0025] 6. The sunshade fabric of the present invention realizes a remarkable effect of reducing the temperature by 5 - 8 °C more than ordinary sunshade curtains through three mechanisms of physical sunshading, radiative cooling and evaporative cooling. It can enhance diffuse reflection and reduce the accumulation of direct heat; reduce the heat transfer coefficient through the radiation layer to reduce heat transfer to the vehicle interior; block heat conduction through the heat insulation layer; absorb the surrounding water vapor through the evaporation layer and cool down through natural convection evaporation.
