Description

Technical Field

[0001] The utility model relates to a warning technology, in particular to a color changing device for reminding a user to pay attention to a high temperature phenomenon generated by a vehicle due to exposure to the sun. Background Art

[0002] Whether going to work or traveling, the vehicle will experience the following situations: outdoors, driving into a parking space, or parked on the side of the road.

DETAILED DESCRIPTION

[0019] Next, embodiments of the present invention are described in conjunction with the accompanying drawings. In the accompanying drawings, the same reference numerals are used to represent the same or similar structures or units. It is foreseeable that the embodiments described are only examples of some of the present invention, not all of the embodiments. Other embodiments can be deduced based on the examples described, or the structures that can be modified or changed as needed are all within the scope of protection of the present invention.

[0020] In the following description, directional terms such as "upper", "lower", "left", "right", "front", "back", "inner", "outer" and "side" are only used to refer to the directions of the drawings. The use of directional terms is for better and clearer description and understanding of the present invention. It does not express or imply that the device or element described must have a specific orientation, structure and operation, and therefore cannot be understood as a limitation on the technical content of the present invention.

[0021] Unless otherwise specified and clearly defined, in the following description, "installed", "connected", "connected" or "provided on" should be understood in a broad sense, such as fixed connection, detachable connection, integral connection, mechanical connection, direct connection, indirect connection or connection between two components. For those skilled in the art in the field of the utility model, they can understand the specific meanings of the above terms in various embodiments and even the utility model by virtue of common knowledge or experience.

[0022] Unless otherwise specified, in the following description, "plurality" means two or more.

[0023] Figure 1 In the utility model, a vehicle is a car 10. The car 10 has a chassis (not shown) that can be equipped with four wheels (not numbered) for driving on a road surface. The car 10 also has a shell (not numbered), which covers the chassis to form an interior space of the car 10. A front windshield (not numbered) is embedded in the front end of the shell, so that a driver in the interior space can observe the road conditions in front of the car 10 through the front windshield. A rear windshield (not shown) is configured at the rear end of the shell, so that the driver can understand the vehicles behind the car 10 through the rear windshield. Four doors are connected to both sides of the shell, which are divided into a driver's door 11, a co-pilot's door (not shown), a left door 14 and a right door (not shown). Four door handles 13 and 15 are provided on the outside of each door, so that the driver, a co-pilot or other passengers can open each door from the outside of the car 10. Two rearview mirrors 12 are mounted on the outside of the driver's door 11 and the co-driver's door to help the driver understand the road conditions on both sides of the vehicle 10 .

[0024] Some cars 10 have an extra rear door (not shown). Usually, the rear windshield is inlaid with the rear door. Of course, the rear door also can be equipped with the required door handle.

[0025] Figure 2 In the embodiment of the present invention, a color changing device 20 is implemented on the exterior of the rearview mirror 12. Figure 5 , the color changing device 20 is implemented on the outside of the door handle 13.

[0026] like Figure 3As shown, the first embodiment of the color changing device 20 adopts the thermochromic principle, utilizing the effect of allotropic deformation at different temperatures, and heating to a temperature above which the crystal state changes to produce optical changes. After cooling, it can return to its original state, so the thermochromic state is reversible.

[0027] In this embodiment, the color changing device 20 includes: a thermochromic film 21 and a symbol (or pattern, trademark) 22 .

[0028] The thermochromic film 21 referred to herein generally refers to a polymer coating obtained by mixing 0.1 to 30 PHR of thermochromic raw materials, 0.1 to 100 PHR of thermoplastic polymer rubber, 0.1 to 20 PHR of filler, 0.1 to 10 PHR of cross-linking agent, and solvent. The polymer coating forms the thermochromic film 21 on the surface of the rearview mirror 12 through a coating and drying method. The thermochromic film 21 has the ability to change color in response to temperature.

[0029] Under the sun, the rearview mirror 12 absorbs heat and generates high temperature. The color changing device 20 senses the temperature rise of the rearview mirror 12, thereby changing to a darker color to remind the driver of the vehicle 10 and other people who may touch the rearview mirror 12 to pay attention to the dangerous state of the rearview mirror 12 being at a high temperature.

[0030] Looking back Figure 2 , a lighter color is the original color of the color changing device 20. Figure 3 The color changing device 20 has a darker color, and the original color is less likely to attract the attention of the driver or other people.

[0031] In terms of color change, the color change device 20 has multiple options. In principle, the color change device 20 has an original color, such as black, white or other colors. Then other colors (i.e. non-original colors) can become the darker color of the color change device 20.

[0032] like Figure 3 As shown, the symbol 22 is an English word, such as "HOT". The thermochromic film 21 is the background, which sets off the obvious characteristics of the symbol 22, so that the color-changing device 20 can achieve the warning level of the reminder. In some embodiments, there is no symbol, and it can be replaced by a pattern or a trademark.

[0033] exist Figure 5 In the figure, the door handle 13 uses the lighter color of the thermochromic film 21 as the background, highlighting a pattern of the symbol 22 (for example, a palm), so that the driver or other people can clearly identify the meaning expressed by the color-changing device 20: the temperature of the door handle 13 is not enough to burn the human body, please feel free to open the door handle 13 with your hand to open the driver's door 11.

[0034] like Figure 6 As shown, the symbol 22 is a prohibition pattern, and the thermochromic film 21 with a lighter white (or eye-catching red) and a darker black (or uneye-catching blue) background highlights the warning that the door handle 13 is strictly prohibited from being touched, which means: the temperature of the door handle 13 is so high that it is scalding, and it is better to open the door after cooling down.

[0035] Figure 4 In the second embodiment of the color changing device, a decorative plate 23 is provided, and the decorative plate 23 includes: a substrate 24, a thermochromic layer 25 and a transparent layer 26. The thermochromic film and / or symbol is applied to one side of the substrate 24 by printing, coating or adhering to form the thermochromic layer 25. The transparent layer 26 is attached to the surface of the thermochromic layer 25 to block an external force from being applied to the thermochromic layer 25, so the transparent layer 26 has a protective function, allowing a ray of light to enter the thermochromic layer 25.

[0036] When in use, the other side of the substrate 24 is attached to the outer surface of a housing 16 (or door handle) of the rearview mirror 12 by means of adhesive. The housing 16 heats up due to exposure to the sun, and the substrate 24 transfers the heat energy of the housing 16 to the thermochromic layer 25. The thermochromic layer 25 senses the heating of the housing 16 (or door handle) through the substrate 24, thereby producing a color change. The driver or other person recognizes the color or symbol of the thermochromic layer 25 through the transparent layer 26, and notices that the rearview mirror 12 should not be touched at this moment, and must wait until the temperature drops before opening the housing 16 (or opening the door handle) to avoid the risk of burns.

[0037] Without departing from the broad concept of the utility model, those skilled in the art can understand and make changes to the above embodiments. Therefore, the utility model is not limited to the specific embodiments disclosed in the specification, and all modifications made according to the spirit and technical scope of the utility model should be covered and protected by the text content defined in the claims.
