Description

Technical Field

[0001] The invention relates to the field of glass, in particular to an automatic defrosting and heating glass. Background Art

[0002] At present, the common way to defrost glass is to cover the glass surface with a heating film. When the heating film is powered on, it can quickly heat the glass surface to melt or remove the frost. This method has been widely used in the fields of front and rear windshields of automobiles, architectural glass, etc., and can effectively solve the problem of glass frosting. However, although this method can achieve glass defrosting, it also has some significant shortcomings and problems.

[0003] First of all, the efficiency of the heating film during the defrosting process is related to the ambient temperature and season. Defrosting is usually performed in winter, but in summer and other warm seasons, the defrosting function is not needed. Therefore, although the heating film has a high transmittance, and most heating films are claimed to have a transmittance of more than 90%, it still brings a shading rate of 1% or less. This may not be ideal in high temperature environments, because the heating film still covers the glass surface when it is not needed, reducing the overall light transmittance and affecting the lighting effect. In addition, some heating films are attached to the glass surface for a long time, which may cause a slight decrease in the appearance and transparency of the glass, and long-term exposure is more prone to aging, reducing the service life.

[0004] Secondly, most heating films are installed on the inner side of the glass. Although this installation method is easy to maintain, it cannot effectively solve the problem of frosting on the outer side of the glass. Especially in extremely cold environments, the outer side of the glass is frosted more seriously, and the heating effect of the inner heating film is limited, making it difficult to quickly defrost the outer side. As a result, the heating and melting efficiency of the outer side frost is greatly reduced, and the user experience is not good.

[0005] In addition, the traditional heating film has a single function, which is mainly used for defrosting the glass, but cannot provide additional protection for the glass, making it easy for the outer side of the glass to frost. At the same time, the existing heating film is usually permanently attached to the glass, which is very difficult to remove and replace, especially the heating film located in the glass interlayer, which is almost impossible to remove and replace. This inconvenience may affect its service life and maintenance cost after long-term use.

[0006] To sum up, while the existing heating film defrosting technology solves the problem of glass frosting, it has many shortcomings such as single function, shading, unreasonable installation position, and inconvenient disassembly and replacement. Therefore, there is an urgent need for a new type of heating defrosting device that can overcome these problems and provide a more flexible and efficient defrosting solution. Summary of the invention

[0007] In order to solve the above problems, the present invention provides an automatic defrosting heated glass, which can realize mobile contact heating defrosting, effectively reduce the degree of frosting, and improve the defrosting efficiency. In addition, the structure of the present invention can be stored and preserved after defrosting is completed, thereby increasing the service life of the heating film and reducing the influence of the heating film on the light transmittance of the glass, effectively solving the shortcomings of the prior art.

[0008] The present invention is realized by the following technical scheme: an automatic defrosting heating glass, comprising a fixing frame, in which a first glass and a second glass are installed, and an intermediate layer is formed between the first glass and the second glass;

[0009] A first guide rail group is installed on the outer sides of the upper and lower ends of the first glass, a first driving rod is installed on the first guide rail group, and a storage cavity is formed inside the first driving rod;

[0010] A second guide rail group is installed on the inner side surfaces of the upper and lower ends of the first glass, and a second driving rod is installed on the second guide rail group;

[0011] A heating film, one end of which is elastically wound in the receiving cavity of the first driving rod, and the other end of which passes through the transition notch on the fixing frame and extends into the middle layer and is fixedly connected to the second driving rod, and the heating film covers the inner side and the outer side of the first glass;

[0012] A protective film is arranged on the outer end of the first glass and covers the heating film. One end of the protective film is fixedly connected to the first driving rod, and the other end of the protective film is fixedly connected to the bottom surface of the accommodating groove opened on the fixing frame. When the first driving rod and the second driving rod move toward and approach the transition notch, the protective film is received in the accommodating groove, and the heating film is elastically rolled up in the receiving cavity of the first driving rod and the rolled-up heating film is used to concentrate heat in the first driving rod, so that the first driving rod serves as a heat concentrator.

[0013] As a preferred technical solution, a reciprocating drive assembly is provided in the first guide rail group and the second guide rail group, the first drive rod and the second drive rod are slidably installed on the guide rail group through a guide slider, and the reciprocating drive assembly is fixedly connected to the guide slider respectively, and the guide slider is driven to reciprocate along the corresponding guide rail group through the reciprocating drive assembly.

[0014] As a preferred technical solution, the reciprocating drive assembly includes a drive belt and drive wheels installed on both sides of the first guide rail group and the second guide rail group. The first guide rail group and the second guide rail group are each provided with an installation cavity. The drive wheels are rotatably installed on both sides of the installation cavity. The drive belt is installed between the two drive wheels. A micro drive motor is installed on one of the drive wheels. The drive wheel is driven by the micro drive motor to drive the reciprocating motion of the drive belt. The drive belt is fixedly connected to the guide slider.

[0015] As a preferred technical solution, a first electromagnet is installed on the side of the first guide rail group farthest from the transition slot, and a second electromagnet is installed on the side of the second guide rail group farthest from the transition slot. When the first electromagnet and the second electromagnet are energized, they are used to adsorb the guide sliders on both sides of the first driving rod and the second driving rod, so as to position the first driving rod and the second driving rod.

[0016] As a preferred technical solution, the first electromagnet and the second electromagnet are both powered on or off by wireless control, or powered on or off by a physical switch.

[0017] As a preferred technical solution, an elastic winding rod is installed in the storage cavity, one end of the heating film is wound on the elastic winding rod, and the heating film is elastically wound by using the elastic winding rod. An open groove is provided on the first driving rod at a position corresponding to the elastic winding rod, and the heating film passes through the open groove.

[0018] As a preferred technical solution, the transition notch includes a transition cavity, a first notch and a second notch, the first notch is arranged on a fixed frame at the outer end of the first glass, the second notch is arranged on a fixed frame at the inner end of the first glass, the first notch and the second notch are respectively communicated with the transition cavity to form a C-shaped structure.

[0019] As a preferred technical solution, a guide roller is installed in the transition cavity, the heating film enters from the first notch and extends from the second notch, and the heating film is in rolling contact with the guide roller.

[0020] As a preferred technical solution, the first driving rod is a metal rod, and the first driving rod forms a heating contact surface relative to the outer side surface of the first glass. Thermal conductive silicone is provided on the heating contact surface. The first driving rod contacts the outer side surface of the first glass through the thermal conductive silicone. The first driving rod is used to absorb the heat after the heating film is rolled up and concentrate the heat.

[0021] As a preferred technical solution, the protective film is a transparent protective film, the heating film is an ITO film or a graphene film, the protective film is connected to the indoor power supply through a power cord, and is controlled to be opened or closed manually or automatically.

[0022] The beneficial effects of the present invention are as follows: the present invention arranges the heating film on the inner and outer sides of the first glass separately, and combines the protective film. When the temperature is low, the heating film and the protective film can be used to cover and protect the outer side of the glass to reduce the frosting rate. Since the inner and outer sides are heated at the same time, when the heating film is powered on for heating, the defrosting efficiency of the glass can be greatly improved.

[0023] When defrosting is required, first release the second driving rod and let the second driving rod move toward the transition notch first. At this time, the heating film can be continuously retracted into the first driving rod. When the second driving rod is displaced to the limit position, release the first driving rod. At this time, the first driving rod also moves toward the transition notch, and the heating film is further rolled up into the first driving rod. During the displacement of the first driving rod, due to the rolling up of the heating film caused by the displacement of the second driving rod, the rolled up heating film concentrates heat in the first driving rod, so that the entire first driving rod is heated and the temperature rises rapidly. Since the first driving rod is in contact with the outer side of the first glass, combined with the temperature and physical contact, the outer side of the first glass can be effectively defrosted during the displacement of the first driving rod until the first driving rod stops after it moves to the limit position of the transition notch.

[0024] Since the defrosting action is completed, the first driving rod and the second driving rod are both located on one side of the transition groove, and the heating film is rolled up in the first driving rod. Therefore, after the entire defrosting action is completed, the heating film can be stored separately without affecting the light transmittance of the glass. At the same time, the separately stored protective film can avoid long-term exposure, that is, the aging problem caused by the sun's radiation is aggravated. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0036] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0037] like Figure 1 and Figure 4 As shown, an automatic defrosting heating glass of the present invention comprises a fixing frame 1, in which a first glass 4 and a second glass 13 are installed, and an intermediate layer is formed between the first glass 4 and the second glass 13;

[0038] It also includes a first guide rail set 6, which is installed on the outer sides of the upper and lower ends of the first glass 4. The first guide rail set 6 is installed with a first driving rod 3, and a storage cavity 19 is formed inside the first driving rod 3;

[0039] It also includes a second guide rail group, which is installed on the inner side surfaces of the upper and lower ends of the first glass 4. The second guide rail group is installed with a second driving rod 23. The first guide rail group 6 has the same structure as the second guide rail group. The first driving rod 3 and the second driving rod 23 are located on the same side when in use and remain in a fixed position.

[0040] It also includes a heating film 22, one end of which is elastically wound in the storage cavity 19 of the first driving rod 3, and the other end of the heating film 22 passes through the transition notch on the fixing frame 1 and extends into the middle layer and is fixedly connected to the second driving rod 23, and the heating film 22 covers the inner and outer sides of the first glass 4. When in use, the heating film 22 is U-shaped as a whole, and the inner and outer sides of the first glass 4 are covered by the heating film 22. In this embodiment, the first glass 4 is the outer side glass, and the second glass 13 is the indoor surface glass;

[0041] It also includes a protective film 21, which is arranged on the outer end of the first glass 4 and covers the heating film 22. One end of the protective film 21 is fixedly connected to the first driving rod 3, and the other end of the protective film 21 is fixedly connected to the bottom surface of the accommodating groove 10 opened on the fixing frame 1; the protective film 21 covers the outside of the heating film 22 as a protective member for the heating film 22. Since the protective film 21 and the heating film 22 both cover the outer side of the first glass 4, the frosting of the glass can be effectively reduced. When rolling up, the protective film 21 can be separately accommodated in the accommodating groove 10 along with the first driving rod 3;

[0042] When the first driving rod 3 and the second driving rod 23 move toward and approach the transition notch, the protective film 21 is stored in the accommodating groove 10, and the heating film 22 is elastically rolled up in the storage cavity 19 of the first driving rod 3 and the rolled up heating film 22 is used to concentrate heat in the first driving rod 3, so that the first driving rod 3 acts as a heat concentrator. When the first driving rod 3 rolls up the heating film 22, the heat of the heating film 22 will be transferred to the first driving rod 3, so that the first driving rod 3 becomes a heating element. Since the heat is concentrated and contacts with the outer side of the first glass 4, the purpose of defrosting can be better achieved. At the same time, the heating film 22 can be stored so that it is not in contact with sunlight, thereby increasing the service life and reducing the aging speed.

[0043] Among them, reciprocating drive components are provided in the first guide rail group 6 and the second guide rail group, and the first drive rod 3 and the second drive rod 23 are both slidably installed on the guide rail group through a guide slider 11, and the reciprocating drive components are respectively fixedly connected to the guide slider 11, and the guide slider 11 is driven by the reciprocating drive component to reciprocate along the corresponding guide rail group. After the heating film 22 is rolled up, if it needs to be used again, the reciprocating drive component is required to make the first drive rod 3 and the second drive rod 23 pull out the heating film 22 and reset it, that is, the reciprocating drive component can be used to reset the first drive rod 3 and the second drive rod 23 to their original positions.

[0044] like Figure 2 As shown, the reciprocating drive assembly includes a drive belt 5 and drive wheels installed on both sides of the first guide rail group 6 and the second guide rail group. The first guide rail group 6 and the second guide rail group are each provided with a mounting cavity 8. The drive wheels are rotatably installed on both sides of the mounting cavity 8. The drive belt 5 is installed between two drive wheels. A micro drive motor 7 is installed on one of the drive wheels. The drive wheel is driven by the micro drive motor 7 to drive the reciprocating motion of the drive belt 5. The drive belt 5 is fixedly connected to the guide slider 11. When the drive belt 5 reciprocates, it can drive the guide slider 11 to reciprocate along the guide rail group.

[0045] Among them, Figure 3 and Figure 7 As shown, a first electromagnet 12 is installed on the side of the first guide rail group 6 that is farthest from the transition slot, and a second electromagnet is installed on the side of the second guide rail group that is farthest from the transition slot. When the first electromagnet 12 and the second electromagnet are energized, they are used to adsorb the guide sliders 11 on both sides of the first drive rod 3 and the second drive rod 23, so as to position the first drive rod 3 and the second drive rod 23. When it is necessary to position the first drive rod 3 and the second drive rod 23, the first electromagnet 12 and the second electromagnet are energized to adsorb the metal guide slider 11, so that the first drive rod 3 and the second drive rod 23 connected to the guide slider 11 are positioned and fixed.

[0046] In this embodiment, the first electromagnet 12 and the second electromagnet are both powered on or off by wireless control, or powered on or off by a physical switch. When the wireless control method is used, a control host and a wireless transceiver module are set at the glass end, and the power is turned on or off by remote control. Of course, a physical control switch can also be directly set to control the power on and off. Of course, a more intelligent method can be used, that is, a temperature sensor can be set to fit the glass surface. When the temperature is detected to be very low, the heating film 22 can be turned on and the electromagnet can be automatically powered on and off.

[0047] Among them, Figure 6As shown, an elastic winding rod 18 is installed in the storage cavity 19, one end of the heating film 22 is wound on the elastic winding rod 18, and the heating film 22 is elastically wound by using the elastic winding rod 18. An opening groove 17 is provided on the first driving rod 3 at a position corresponding to the elastic winding rod 18, and the heating film 22 passes through the opening groove 17. When the second driving rod 23 is displaced, the heating film 22 can be rolled up by the elastic winding rod 18. When the first driving rod 3 is displaced, the elastic winding rod 18 can also be continued to be used for winding.

[0048] like Figure 5 As shown, the transition notch includes a transition cavity 16, a first notch 9 and a second notch 14. The first notch 9 is arranged on the fixing frame 1 at the outer end of the first glass 4, and the second notch 14 is arranged on the fixing frame 1 at the inner end of the first glass 4. The first notch 9 and the second notch 14 are respectively communicated with the transition cavity 16 to form a C-shaped structure. Some sealing cotton can be arranged at the positions of the first notch 9 and the second notch 14. The sealing cotton is used to contact the front and back surfaces of the heating film 22 to achieve the purpose of cleaning the heating film 22 and reducing air flow. A rubber layer is arranged on the side of the first driving rod 3 relative to the first notch 9. When the first driving rod 3 is displaced to the position of the first notch 9, the first driving rod 3 is attached to the first notch 9 to achieve the purpose of blocking the first notch 9. Figure 7 shown.

[0049] In order to make the heating film 22 roll up more smoothly, in this embodiment, a guide roller 15 is installed in the transition cavity 16, and the heating film 22 enters from the first slot 9 and extends from the second slot 14, and the heating film 22 is in rolling contact with the guide roller 15.

[0050] In this embodiment, the first driving rod 3 is a metal rod, and the first driving rod 3 forms a heating contact surface relative to the outer side of the first glass 4. The heating contact surface is provided with heat-conductive silicone. The first driving rod 3 contacts the outer side of the first glass 4 through the heat-conductive silicone. The first driving rod 3 is used to absorb the heat of the heating film 22 after it is rolled up and concentrate the heat. Since the heat of the first driving rod 3 is concentrated and the first driving rod 3 is in physical contact with the first glass 4, the first driving rod 3 can maintain a defrosting mode in a physical contact manner, so as to achieve the purpose of simultaneous heating and physical defrosting, thereby greatly improving the defrosting efficiency. Before the first driving rod 3 is displaced, the heating film 22 can cover the glass surface for heating to melt the frost on the glass surface, so as to achieve the purpose of heating and defrosting.

[0051] In this embodiment, the protective film 21 is a transparent protective film 21, and the heating film 22 is an ITO film or a graphene film. The protective film 21 is connected to the indoor power supply through a power cord, and is controlled to be opened or closed manually or automatically. In order to improve the pulling strength of the heating film 22, in this embodiment, a thickened portion can be provided at the edge of the heating film 22, or the thickness of the heating film 22 can be increased to solve this problem.

[0052] The defrosting process is as follows:

[0053] When defrosting is required, the heating film 22 is opened, the first driving rod 3 and the second driving rod 23 remain in a stationary positioning state, the heating film 22 heats the inner and outer sides of the first glass 4, and the defrosting action is performed first. In order to improve the defrosting efficiency, the second driving rod 23 can be released first, and the second driving rod 23 is moved toward the transition notch first. At this time, the heating film 22 can be continuously retracted into the first driving rod 3. When the second driving rod 23 is displaced to the limit position, the first driving rod 3 is released. At this time, the first driving rod 3 also moves toward the transition notch, and the heating film 22 is further The heating film 22 is rolled up into the first driving rod 3. During the displacement of the first driving rod 3, the heating film 22 is rolled up due to the displacement of the second driving rod 23. Therefore, the rolled up heating film 22 concentrates the heat in the first driving rod 3, so that the entire first driving rod 3 is heated and the temperature rises rapidly. Since the first driving rod 3 is in contact with the outer side of the first glass 4, combined with the temperature and physical contact, the outer side of the first glass 4 can be effectively defrosted during the displacement of the first driving rod 3 until the first driving rod 3 stops after being displaced to the limit position of the transition notch.

[0054] Since the defrosting action is completed, the first driving rod 3 and the second driving rod 23 are both located on one side of the transition groove, and the heating film 22 is rolled up in the first driving rod 3. Therefore, after the entire defrosting action is completed, the heating film 22 can be separately stored without affecting the light transmittance of the glass. At the same time, the separately stored protective film 21 can avoid long-term exposure, that is, the aging problem caused by sunlight. When it needs to be used again, the first driving rod 3 and the second driving rod 23 can be reset to wait for the next use. If it is in a season with higher temperatures, the heating film 22 can remain rolled up.

[0055] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope defined in the claims.
