[0002] As the level of vehicle intelligence gradually increases, the demand for dimming, display, lighting and other functions integrated on window glass is increasing. Window glass with these functions usually connects functional components to the electronic control unit (ECU) through cables to achieve different functions.

[0003] Unlike the front windshield, rear windshield and other fixed window glasses, the door glass needs to be raised and lowered, and the cables are easily damaged during multiple movements. Once the cables are damaged, the door glass needs to be replaced as a whole, which is costly and difficult. Therefore, when functional components are used in door glass, the safety factor of the cables is one of the key factors that need to be considered. Utility Model Content

[0004] The purpose of the present disclosure is to solve the above-mentioned problems in the prior art and to provide a cable connector for a vehicle door glass, which can safely achieve the functional effect of the vehicle door glass while providing reliable protection for the cable.

[0027] The implementation and use of the embodiments are discussed in detail below. However, it should be understood that the specific embodiments discussed are merely exemplary of specific ways to implement and use the present disclosure, and are not intended to limit the scope of the present disclosure. When describing the structural positions of the various components, such as up, down, top, bottom, etc., the expressions of directions are not absolute, but relative. When the various components are arranged as shown in the figure, these directional expressions are appropriate, but when the positions of the various components in the figure change, these directional expressions also change accordingly.

[0028] Herein, the expression "includes" or similar expressions "having" and the like are open-ended and do not exclude additional unrecited elements, steps or components.

[0029] Herein, the terms "first", "second", etc. are not used to limit the order of precedence and the number of components, unless otherwise specified.

[0030] In this document, unless otherwise specifically defined, the terms "installation", "connection", "attachment" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meanings of the above terms in this document can be understood according to the specific circumstances.

[0031] Herein, the "surface" of a glass body is defined by the plane where the length and width of the glass body lie, and the "edge" is defined by the plane where the length or width and thickness or height of the glass body lie. A "cross section" of a glass component is taken along the thickness or height direction of the glass component.

[0032] In the various embodiments described, unless otherwise specified, the thickness of the glass body is the thickness commonly used in the art, and the thickness of each laminated structure on the glass body is applicable to the conventional range and is not limited to that shown in the figure. In addition, although the figure shows flat glass, the door glass of the present disclosure can also be curved glass. In various embodiments, it is described as an independent glass body, but in some cases not described, the surface of the glass body can also use a special coating to improve other properties such as heat insulation and / or comfort.

[0033] The application of functional components on car window glass to achieve different functional effects has been widely favored by manufacturers and consumers. Depending on the different functional effects that need to be achieved, the functional components include, for example, at least one of dimming components, display components, lighting components, heating components, and touch components. In order to achieve the functional effects, these functional components are integrated on the car window glass by attaching (for example, bonding) to the glass surface or attaching (for example, sandwiching and laminating) between laminated glasses, and need to be electrically connected to the electronic control unit (ECU) through cables to power the functional components and transmit control signals. For example, Figure 1A A vehicle door glass assembly 100 in a form shown in the figure includes a glass body 110 and a functional component. The functional component may be a dimming component 120 sandwiched in the glass body 110, such as a dimming film, which can adjust the brightness of the light in the vehicle door glass assembly 100 through an electronic control unit. Alternatively, the functional component may also be a display component such as a display film, which can enable the vehicle door glass assembly to display information through an electronic control unit. Figure 1B In the vehicle door glass assembly 100-1 of the illustrated embodiment, the functional component may be a lighting component 160 attached (bonded or embedded) to the glass body 110, such as a light emitting diode (LED) strip, which can be controlled by an electronic control unit to obtain a lighting effect, or different colors, breathing lights, flowing lights and other ambient lighting effects can be achieved by using different control strategies for the LED strip.

[0034] For door glass with functional effects, due to frequent lifting and movement during use, the cables that electrically connect the functional components to the electronic control unit also need to move frequently, and may break during the pulling process, making the functional effect of the door glass unattainable. Therefore, the safety factor of the cable has become one of the key factors for the safe and reliable operation of functional door glass.

[0035] According to the concept of the present disclosure, a cable connector for a vehicle door glass is provided. During the movement of the vehicle door glass, the pulling force is only applied to the cable connector instead of the cable of the functional component, thereby ensuring that the cable of the functional component will not be directly affected by the pulling force, thereby ensuring the implementation of the functional effect of the vehicle door glass.

[0036] Still refer to Figure 1A and Figure 1B When the door glass assembly 100 is installed on the vehicle and the glass body 110 is in a fully used state (i.e., when the glass window of the door is fully closed), the glass body 110 is suitable for cooperating with the water-cut strip 130 (also called a sealing strip). The water-cut strip refers to a rubber sealing strip located between the door glass and the door sheet metal (not shown) at the lower part of the door glass, which is used to cut off water droplets, water mist and dust on the surface of the glass body when lifting the door glass, and also serves an aesthetic purpose. In addition, the glass body 110 is attached to the door sheet metal through a lifting mechanism such as a door clamp component 140 to achieve, for example, lifting and lowering in a vertical direction (roughly perpendicular to the ground). The lifting mechanism is well known in the art and will not be described in detail here.

[0037] According to the present disclosure, a cable connector is provided, comprising a connection block 150 and a first cable 151, wherein the connection block 150 is adapted to be attached to a surface of a door glass or a glass body 110, wherein one end of the first cable 151 is attached to the connection block 150 and the other end is electrically connected to an electronic control unit. Advantageously, the connection block 150 is attached to a second cable of a functional component, e.g. Figure 1A In the embodiment shown, the second cable 121 is attached to the dimming component 120, or Figure 1B In the illustrated embodiment, the second cable 161 is attached to the lighting component 160, and the first cable 151 is electrically connected to the second cable 121 or 161. In other words, the second cable 121 or 161 of the functional component is electrically connected to the first cable 151 leading out of the glass body 110 via the cable connector, so that the power supply and control signal transmission of the functional component are realized via the cable connector, and the functional effect of the functional component is realized. It should be understood that the first cable and the second cable here do not mean a single wire harness, but an integration of multiple wire harnesses that can realize functions such as power supply and control signal transmission of the functional component.

[0038] In this way, since the cable connector is attached to the glass body and constitutes an integral whole, the first cable is used as an external cable connected to the electronic control unit. When the glass body is driven to move up and down, the pulling force on the door glass assembly is only applied to the cable connector, that is, the first cable and / or the connection position of the first cable and the connecting block, and will not be applied to the second cable of the functional component attached to the cable connector (or the internal cable of the door glass assembly), which can effectively protect the second cable and ensure the reliable use of the functional component. Even if the first cable of the cable connector is damaged or broken, depending on the connection method between the first cable and the connecting block, the first cable or the cable connector including the first cable and the connecting block can be easily disassembled and replaced without replacing the glass body with the functional component, which is cost-effective and reduces the difficulty of maintenance and replacement.

[0039] Advantageously, the cable connector is configured such that when the connection block is attached to the surface of the door glass, the connection between the second cable and the connection block is not affected by the connection between the first cable and the connection block. That is, the connection force between the connection block and the surface of the door glass is advantageously set to be greater than the connection force between the first cable and the connection block, so that, for example, when the first cable breaks due to force or the first cable and the connection block are disconnected due to force, the connection block and the surface of the door glass remain attached, and the second cable of the functional component remains attached to the connection block, thereby effectively protecting the second cable.

[0040] Advantageously, the cable connector is arranged so as not to interfere with surrounding components (such as the lifting mechanism) on the door sheet metal, that is, no matter what the structure of the connecting block of the cable connector is, or what form the first cable is, the existence of the connecting block will not affect the normal implementation of the lifting movement of the glass body, and the movement range of the first cable is limited to a certain extent, thereby protecting the first cable and avoiding damage or breakage caused by entanglement with surrounding components. Figure 1A and Figure 1B It can be seen that in the illustrated embodiment, the cable connector is arranged below the water-cutting strip 130 and advantageously arranged adjacent to the edge of the glass body 110, specifically adjacent to the left bottom edge of the glass body 110 in the illustrated embodiment, which can reduce the length of the first cable 151 extending out of the connection block, further avoiding damage or breakage caused by entanglement with surrounding components. Figure 2A The vehicle door glass assembly 100-2 and Figure 2B In the vehicle door glass assembly 100 - 3 of the illustrated embodiment, the cable connector is also arranged below the water-cut strip 130 , but is arranged adjacent to the lower bottom edge of the illustrated glass body 110 . Figure 3A The vehicle door glass assembly 100-4 and Figure 3BIn the vehicle door glass assembly 100-5 of the illustrated embodiment, the cable connector is also arranged below the water cut strip 130, but is arranged adjacent to the right bottom edge of the illustrated glass body 110. Here, the "bottom" of the glass body refers to the surface portion of the glass body that faces the bottom of the vehicle or the ground when the glass body is installed to the vehicle in a substantially vertical direction, and the portion may be inclined or substantially vertical relative to the ground.

[0041] It should be understood that the shape, size and arrangement of the connection block 150 shown in the figure are only examples. Depending on different needs, such as the arrangement position of the electronic control unit and the structural layout on the door sheet metal, the connection block 150 can be arranged at any suitable position to meet the needs of beautifying the appearance and function. In addition, only one cable connector is shown in each exemplary embodiment, but the number of cable connectors is not limited. For example, in some embodiments, the door glass assembly may have multiple functional components to achieve a variety of different functional effects. For multiple functional components, the second cables of each functional component can be attached to the same cable connector and connected to the electronic control unit, that is, the integration of multiple second cables of multiple functional components can be achieved through one cable connector. Since the first cable of the cable connector is still connected to the electronic control unit, effective protection of multiple second cables can be achieved. In some embodiments, the door glass assembly can achieve multiple different functions in multiple regions, and the second cables of different functional components in different regions can be attached to one cable connector respectively, that is, multiple cable connectors with the same number of functional components can be included, and then multiple first cables of multiple cable connectors can be integrated and connected to the electronic control unit. Regardless of the number of cable connectors, the cable connectors are arranged so as not to interfere with surrounding components on the door sheet metal.

[0042] In some embodiments, the connection block 150 and the first cable 151 can be attached to each other by any one of a conductive adhesive, welding, a threaded connector, a plug connector, a snap connector, and a push connector. When a threaded connector, a plug connector, a snap connector, or a push connector is used, a detachable connection can be formed between the connection block 150 and the first cable 151, so that only the first cable can be quickly and conveniently maintained and replaced when the first cable is damaged or broken. When a conductive adhesive or welding is used, once the connection position between the first cable and the connection block is damaged or broken, only the first cable can be quickly and conveniently maintained and replaced, such as re-bonding or welding. When a threaded connector, a pin connector, a snap connector, a push connector, etc. are used, the connection end where the connection block 150 is attached to the first cable 151 can be configured as a first connection end of any one of the threaded connector, the pin connector, the snap connector, and the push connector, and the connection end where the first cable 151 is attached to the connection block 150 can be configured as a second connection end that matches the first connection end. The threaded connector, the pin connector, the snap connector, and the push connector are all connection methods known in the art and will not be described in detail herein.

[0043] Advantageously, the connecting block 150 and the first cable 151 of the cable connector can be formed as one piece. For example, after the connecting end of the first cable 151 is attached to the connecting end of the connecting block 150 in the above manner, the other parts of the connecting block 150 can be formed by injection molding to form the two as one piece. The one-piece cable connector can increase the stress level of the connecting block and the first cable as a whole, so that the first cable (especially the attachment point of the first cable and the connecting block) can be further protected by the connecting block attached to the surface of the vehicle window glass, avoiding or reducing the risk of damage or breakage of the first cable (especially the attachment point of the first cable and the connecting block). In addition, the one-piece cable connector can be used as a single component for various forms of vehicle door glass, and has a wider application. As an example, optional injection molding materials for the connection block 150 include, but are not limited to, polycarbonate (PC), acrylonitrile-butadiene-styrene copolymer (ABS), a mixture of polycarbonate and acrylonitrile-butadiene-styrene copolymer (PC / ABS), polybutylene terephthalate (PBT), and polyamide (PA, for example, polyhexamethylene adipamide (PA66, commonly known as nylon-66)).

[0044] Regarding the connection method between the connection block 150 and the glass body 110, most of the connection block 150 or the entire connection block 150 can be attached to the surface of the glass body by any one of adhesive, threaded connector, and snap-on connector. Depending on different connection methods, the size of the connection area where the connection block is attached to the surface of the glass body can be set to provide sufficient connection strength, thereby ensuring that the connection between the second cable and the connection block is not affected by the connection between the first cable and the connection block. Adhesive can be preferably used as an economical and convenient connection method. Figure 4A The embodiment exemplarily shows a method of using an adhesive 170 , and the connection block 150 is exemplarily bonded to one surface of the glass body 110 . Figure 4B In the illustrated embodiment, the connection block 150 may be bonded to one surface and an edge of the glass body 110 by an adhesive 170 . Figure 4C In the illustrated embodiment, the connection block 150 can be bonded to the two surfaces and the edge of the glass body 110 by means of an adhesive 170. In an optional manner, a through hole can be formed on the glass body to achieve connection using a threaded connector such as a screw or a snap-on connector. For example, for the snap-on connector connection, a snap-on portion with a snap hook can be passed through the through hole from one side of the glass body and snap-on-embedded into a snap-on portion with a snap groove on the other side of the glass body, thereby achieving connection.

[0045] Similar to the way the first cable is attached to the connection block, the connection block can be attached to the second cable by any one of conductive adhesive, welding, threaded connector, plug connector, snap-on connector, and push connector depending on different needs. FIG. 4A to FIG. 4CThe second cable 121 of the dimming component 120 is taken as an example, and the second cable 121 is led out from the glass body 110 and attached to the connection block 150. When the connection block 150 is bonded to the glass body 110 by the adhesive 170, the way in which the second cable 121 is led out from the glass body 110 and attached to the connection block 150 can be selected according to different needs, and is not limited here. For example, the second cable 121 can be attached to the surface of the glass body 110 by overall bonding, partial bonding, or fixed buckle, and then attached to the connection block 150, or it can be directly attached to the connection block 150 without bonding or fixing to the glass body 110, or it can be attached to the surface of the glass body 110 by, for example, the adhesive 170, and then attached to the connection block 150. In addition, although the second cable 121 or 161 is attached to the connection block 150 from the side opposite to the first cable 151 in various embodiments shown in the figure, the shape of the connection block 150 can be designed according to actual needs, so the second cable can also be arranged at other positions of the connection block 150, for example, on the same side as the first cable 151. Similarly, when a threaded connector, a pin connector, a snap connector, a push connector, etc. are used, the connection end where the connection block 150 and the second cable 121 are attached can be configured as a first connection end of any one of the threaded connector, the pin connector, the snap connector, and the push connector, and the connection end where the second cable 121 and the connection block 150 are attached can be configured as a second connection end that matches the first connection end.

[0046] The form of the first cable 151 or the external cable can be selected according to different needs, for example, at least including a wire in the core, a protective layer covering the wire, and a waterproof layer covering the protective layer, etc. The form of the second cable 121 or the internal cable can also be selected according to different needs, for example, it can be selected as a wire or a flexible printed circuit board (FPC), etc.

[0047] As can be seen from the above description, due to the provision of a cable connector, during the movement of the glass body, the pulling force is only applied to the first cable and / or the connection between the first cable and the connecting block, and the second cable will not be directly affected by the pulling force, thereby providing effective protection for the second cable and ensuring the reliable implementation of the functional effect. Even if the first cable is damaged or broken, the cable connector or the first cable can be conveniently maintained and replaced without causing the overall replacement of the door glass assembly. The cable connector disclosed in the present invention has the advantages of simple structure, significant performance improvement and cost-effectiveness, and is suitable for a wide range of applications.

[0048] It should be understood here that the embodiments shown in the figures only show the optional architecture, shape, size and arrangement of the various optional components of the door glass assembly and cable connector according to the present disclosure, but they are only for illustration and not limitation, and other shapes, sizes and arrangements may also be adopted without departing from the concept and scope of the present disclosure.

[0049] The technical content and technical features of the present disclosure have been disclosed above. However, it can be understood that under the creative ideas of the present disclosure, technicians in this field can make various changes and improvements to the above disclosed concepts, but they all belong to the protection scope of the present disclosure. The description of the above implementation mode is illustrative rather than restrictive, and the protection scope of the present disclosure is determined by the claims.
