Description

Technical Field

[0001] This utility model relates to the field of automotive sunroof technology, and in particular to a sunshade and light-blocking sealing structure for automotive sunshades. Background Technology

[0002] With the development of the automotive industry, consumers have increasingly stringent requirements for driving and riding comfort, and more spacious interiors have become a key factor for many consumers. Currently, many manufacturers are converting existing sliding sunroofs into fixed sunroofs, which not only provides better lighting inside the vehicle but also eliminates the need for moving parts, giving drivers and passengers more headroom. However, tinted or color-changing glass alone cannot effectively block sunlight, especially under the scorching summer sun, where the car's air conditioning cannot eliminate the poor driving and riding experience caused by strong light. Therefore, the design of adding sunshades under the sunroof has emerged, effectively adjusting the light in time to provide a better experience for drivers and passengers. However, even when the sunshade is closed, light still leaks in, and it cannot effectively block all the light from the roof, resulting in a poor driving and riding experience.

[0003] In existing technologies, such as Figure 1 and Figure 2 As shown, the traditional method involves hiding the sunshade handle 500 behind the front drainage channel 300. The C-shaped handle receiving slot 310 engages with the sunshade handle 500, and the folded gap can effectively block light that travels in a straight line. This method can effectively prevent light leakage into the car due to light reflection. However, since the sunshade handle 500 is a moving part, the C-shaped handle receiving slot 310 needs to maintain a sufficient movement gap with the sunshade handle 500. Because it cannot completely block light, light leakage into the car occurs due to diffuse reflection. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the technical problem to be solved by this utility model is to provide a car sunshade curtain light-blocking and sealing structure that can completely block light and prevent light leakage inside the car, while also reducing the occupation of head space and improving the driving experience.

[0005] This utility model proposes a sunshade sealing structure for automobiles, including a snap-fit ​​part and a blocking part. The snap-fit ​​part snaps onto the snapped part located at the rear end of the front drainage channel. The blocking part is fixed to the snap-fit ​​part. The sunshade handle drives the curtain to move towards the front drainage channel to a predetermined position. The blocking part is attached to and pressed against the sunshade handle at the end away from the snap-fit ​​part.

[0006] Preferably, the snap-fit ​​portion has a cavity that mates with the snap-fit ​​portion, and the cavity has at least one barb structure.

[0007] Preferably, the blocking part includes an elastic sealing strip, one end of which is fixedly connected to the snap-fit ​​part, and the other end of which is a free end; the sunshade handle is attached to and squeezes the outer periphery of the free end to achieve light blocking.

[0008] Preferably, the hardness of the elastic sealing strip is ≤45HA.

[0009] Preferably, the outer periphery of the elastic sealing strip is provided with a lubricating coating to reduce stress concentration at the point where the outer periphery of the elastic sealing strip is pressed against the sunshade handle.

[0010] Preferably, the shielding portion further includes a groove for enhancing the deformation of the elastic sealing strip, the groove being formed on the inner periphery of the elastic sealing strip.

[0011] Preferably, the snap-fit ​​portion is embedded with a core wire for enhancing structural strength.

[0012] Preferably, both the snap-fit ​​portion and the shielding portion are made of TPV material.

[0013] Preferably, the large end of the engaging portion is provided with a hook-shaped structure, which engages with the barb structure at the bottom of the cavity, and the size of the hook-shaped structure is larger than the gap at the cavity entrance.

[0014] Preferably, the top of the rear end of the front drainage channel is open.

[0015] As described above, the car sunshade sealing structure of this utility model has the following beneficial effects:

[0016] This invention prevents the locking part and the blocking part from falling off by locking the locking part onto the locking part. When the sunshade handle moves the curtain towards the drainage channel to the predetermined position, the sunshade handle adheres to and squeezes the blocking part at the end away from the locking part, causing it to deform and thus blocking the light from the roof from entering the vehicle.

[0017] This utility model has a compact structure and is easy to install. It can move the entire sunshade frame upward, reducing the occupation of head space and providing more light-transmitting space when the sunshade is open, thus improving the driving and riding experience.

[0018] This invention, through the action of the shielding part, can effectively prevent the increased running resistance of the sunshade handle caused by compressed air, which in turn causes the motor current to rise excessively and trigger the anti-pinch mechanism. Attached Figure Description

[0027] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0028] It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings of this specification are only for illustrative purposes and to aid those skilled in the art in understanding and reading the content disclosed herein. They are not intended to limit the implementation conditions of this utility model and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to the size, without affecting the effects and objectives achieved by this utility model, should still fall within the scope of the technical content disclosed herein. Furthermore, the terms used in this specification, such as "upper," "lower," "left," "right," and "middle," are merely for clarity of description and are not intended to limit the scope of implementation of this utility model.

[0029] like Figures 3 to 6As shown, an embodiment of a car sunshade shading and sealing structure includes a snap-fit ​​portion 100 and a blocking portion 200. The snap-fit ​​portion 100 is preferably snapped onto the snapped portion 400 located at the rear end of a front drainage channel 300 in an inverted manner. The top of the rear end of the front drainage channel 300 is open, allowing the entire sunshade frame to be moved upwards, reducing the occupancy of headroom for the driver and passengers. The blocking portion 200 is fixed to the snap-fit ​​portion 100. When shading is needed, pulling the sunshade handle 500 moves the curtain 510 towards the forward drainage channel 300 to a predetermined position. At this time, the blocking part 200 is in contact with the sunshade handle 500 at the end away from the locking part 100, and the sunshade handle 500 presses against the blocking part 200, causing the blocking part 200 to deform to a certain extent. This allows for a tight fit between the blocking part 200 and the sunshade handle 500, effectively blocking light entering the vehicle from the roof glass 700 and preventing light leakage from the sunshade. Simultaneously, the top of the rear end of the forward drainage channel 300 is open, effectively preventing compressed air from significantly increasing the running resistance of the sunshade handle 500, which could lead to an excessive increase in motor current and trigger the anti-pinch mechanism. It should be noted that, compared to existing technologies, the overlap between the sunshade handle 500 and the opening of the roof 600 along the X-axis in this embodiment can be compressed to the maximum extent, thereby increasing the opening size of the roof along the X-axis. When light needs to pass through, pull the sunshade handle 500 away from the drainage channel 300 back to the initial position to provide more light-passing space.

[0030] In one embodiment, such as Figure 4 and Figure 5 As shown, the snap-fit ​​part 100 has a cavity 110 that mates with the snap-fit ​​part 400. The opening of the cavity 110 gradually increases in size towards the inside. The bottom of the cavity 110 can accommodate the end of the snap-fit ​​part 100. The cavity 110 has at least one barb structure 120, so that when the snap-fit ​​part 100 is upside down on the snap-fit ​​part 400, the snap-fit ​​part 400 and the snap-fit ​​part 100 engage with each other, so as to prevent the snap-fit ​​part 110 and the shielding part 200 from falling off due to accidental contact during installation, transportation and subsequent use.

[0031] In one embodiment, such as Figure 4 and Figure 5 As shown, the sunshade portion 200 includes an elastic sealing strip 210. One end of the elastic sealing strip 210 is fixedly connected to the snap-fit ​​portion 100, and the other end of the elastic sealing strip 210 is a free end, meaning that both ends of the elastic sealing strip 210 are not closed and have openings. The outer and inner peripheries of the elastic sealing strip are preferably arc-shaped. When the sunshade handle 500 moves in the direction of the elastic sealing strip 210, until the sunshade handle 500 adheres to and squeezes the outer periphery of the free end of the elastic sealing strip 210, light is blocked, effectively preventing light from shining into the vehicle through the roof glass, thereby improving the driving and riding experience.

[0032] Furthermore, the elastic sealing strip 210 at the snap-fit ​​portion 100 may be made of, but is not limited to, TPV material (thermoplastic vulcanized rubber), TPE material (thermoplastic elastomer), TPU material (thermoplastic polyurethane), etc., which can be determined by technicians according to the actual working conditions. Since the elastic sealing strip 210 needs to be deformed by the sunshade handle 500 and conform to it to achieve light blocking, the snap-fit ​​portion 100 snaps onto the snapped portion 400. To provide a stable snap-fit ​​force, the snap-fit ​​portion 100 needs to have high rigidity; therefore, the hardness of the snap-fit ​​portion 100 is greater than the hardness of the elastic sealing strip 210. Preferably, the hardness of the elastic sealing strip 210 is ≤45HA to ensure sufficient deformation, and the hardness of the snap-fit ​​portion 100 is preferably 60HA~100HA, which, in conjunction with the barb structure 120, provides a stable snap-fit ​​force.

[0033] Furthermore, such as Figure 5 As shown, the large end of the snap-fit ​​part 400 is provided with a hook-shaped structure 410. During the installation process, the cavity 110 of the snap-fit ​​part is inverted and placed on the snap-fit ​​part 400, so that the hook-shaped structure 410 engages with the barbed structure 120 at the bottom of the cavity 110. The size of the hook-shaped structure 410 is larger than the gap at the entrance of the cavity 110 to ensure that the snap-fit ​​part 100 can be smoothly snapped onto the snap-fit ​​part 400, so as to provide a stable snap-fit ​​force and prevent it from falling off easily.

[0034] In one embodiment, the blocking portion 200 further includes a groove 220 for enhancing the deformation of the elastic sealing strip 210. The area where the groove 220 is located forms a deformation zone, and the groove 220 is formed on the inner periphery of the elastic sealing strip 210. When light blocking is required, the sunshade handle 500 moves toward the elastic sealing strip 210 and presses against it. The elastic sealing strip 210 is subjected to pressure from the sunshade handle 500, which promotes deformation of the deformation zone where the groove 220 is located. This causes the area where the elastic sealing strip 210 and the sunshade handle 500 are in contact to move downward under the action of overcoming the elastic force, so as to fully block the light entering the vehicle from the roof glass 700 and prevent light leakage from the sunshade. When light needs to pass through, the sunshade handle 500 is moved to the initial state, and the elastic sealing strip 210 quickly returns to its original position under the action of the elastic force.

[0035] Furthermore, considering that the outer peripheral surface of the elastic sealing strip 210 is relatively rough, it is prone to wrinkles, twisting, and other uncontrollable factors when pressed against the sunshade handle 500. The outer peripheral surface of the elastic sealing strip 210 is provided with a lubricating coating 211 to reduce stress concentration at the point where the outer peripheral surface of the elastic sealing strip 210 is pressed against the sunshade handle 500.

[0036] In one embodiment, the snap-fit ​​portion 100 is embedded with a core wire 130 to increase the overall structural strength of the snap-fit ​​portion. The core wire 130 may include, but is not limited to, glass fiber, and may also be made of aramid fiber, basalt fiber, modified natural fiber, etc., which can be determined by technicians based on the actual working conditions.

[0037] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
