Description

Technical Field

[0001] This application relates to the field of electrochromic technology, and more particularly to an electrochromic device and electrochromic glasses. Background Technology

[0002] Electrochromic devices have the characteristic that the properties of light change in response to changes in voltage across their terminals, and are widely used in automotive rearview mirrors, sunroofs, side windows, curtain walls, smart glasses and other fields.

[0003] Generally, electrochromic films receive power from an external power source through two lead-out structures, which are respectively connected to two conductive layers of the electrochromic film. Due to the multilayer structure of the electrochromic film, these two lead-out structures are located on different film layer surfaces, resulting in an inherent height difference between them. This increases the difficulty of connecting to an external power source. In addition, at least one lead-out structure needs to be bent when connecting to an external power source. This bending operation can easily cause stress concentration at the bending point, leading to breakage of the lead-out structure during long-term use or under external force, affecting the reliability of the electrical connection.

[0026] like Figure 1 and Figure 2 As shown, an embodiment of this application provides an electrochromic device 100, which includes an electrochromic film 110, a lead-out circuit board 120, a first lead-out structure 131, and a second lead-out structure 132.

[0027] Among them, such as Figure 1As shown, the electrochromic film 110 includes a first conductive layer 111, an electrochromic layer 112, and a second conductive layer 113 stacked sequentially. Applying a voltage between the first conductive layer 111 and the second conductive layer 113 can change the optical state of the electrochromic layer 112, causing the device having the electrochromic device 100 to exhibit reversible changes in color and transparency.

[0028] A sealant 114 is provided around the first conductive layer 111, the electrochromic layer 112, and the second conductive layer 113. A barrier layer 115 is also provided on the outer side of the first conductive layer 111 and the outer side of the second conductive layer 113 to protect the electrochromic film 110.

[0029] Sealant 114 is used to prevent the penetration of moisture and oxygen, and to avoid oxidation, degradation, or obstruction of ion migration pathways in electrochromic materials. Sealant 114 also has electrical insulation properties and is made from materials such as epoxy resin, polyurethane, and UV-curable adhesive.

[0030] The barrier layer 115 is used to prevent scratches on the film material and can be a PET layer.

[0031] See Figure 1 The first electrical connection terminal 121 of the circuit board 120 is led out. One end of the first lead-out structure 131 is fixedly connected to the first conductive layer 111, and the other end of the first lead-out structure 131 is fixed to the lead-out circuit board 120 and electrically connected to the first electrical connection terminal 121.

[0032] In one embodiment, the first lead-out structure 131 is an extension of the first conductive layer 111. The first conductive layer 111 is cut to form the first conductive layer 111 and the first lead-out structure 131 extending or protruding outward from the edge of the first conductive layer 111. The first conductive layer 111 and the first lead-out structure 131 are an integral structure. The lead-out circuit board 120 can be fixed to the first lead-out structure 131 by means of conductive adhesive (such as ACF, Anisotropic Conductive Film) bonding or soldering, thereby achieving an electrical connection between the lead-out circuit board 120 and the first lead-out structure 131.

[0033] In another embodiment, the first lead-out structure 131 is a flexible conductive structure, such as an FPC or copper foil. One end of the second lead-out structure 132 can be sandwiched between the first conductive layer 111 and the barrier layer 115 adjacent to the first conductive layer 111, or one end of the first lead-out structure 131 can be connected to the side of the first conductive layer 111 facing the electrochromic layer 112. The first lead-out structure 131 is electrically connected to the lead-out circuit board 120 and the first conductive layer 111, respectively, to achieve an electrical connection between the lead-out circuit board 120 and the first conductive layer 111.

[0034] See Figure 2The lead-out circuit board 120 includes a second electrical connection terminal 122. The second lead-out structure 132 is spaced apart from and insulated from the first lead-out structure 131. One end of the second lead-out structure 132 is fixedly connected to the second conductive layer 113, and the other end of the second lead-out structure 132 is fixed to the lead-out circuit board 120 and electrically connected to the second electrical connection terminal 122.

[0035] In one embodiment, the second lead-out structure 132 is an extension of the second conductive layer 113. The second conductive layer 113 is cut to form the second conductive layer 113 and the second lead-out structure 132 extending or protruding outward from the edge of the second conductive layer 113. The second conductive layer 113 and the second lead-out structure 132 are an integral structure. The lead-out circuit board 120 can be fixed to the second lead-out structure 132 by means of conductive adhesive (such as ACF, Anisotropic Conductive Film) bonding or soldering, thereby achieving an electrical connection between the lead-out circuit board 120 and the second lead-out structure 132.

[0036] In another embodiment, the second lead-out structure 132 is a flexible conductive structure, such as an FPC or copper foil. One end of the second lead-out structure 132 can be sandwiched between the second conductive layer 113 and the barrier layer 115 adjacent to the second conductive layer 113, or one end of the second lead-out structure 132 can be connected to the side of the second conductive layer 113 facing the electrochromic layer 112. The second lead-out structure 132 is electrically connected to the lead-out circuit board 120 and the second conductive layer 113, respectively, to realize the electrical connection between the lead-out circuit board 120 and the second conductive layer 113.

[0037] See also Figure 1 and Figure 2 The first lead-out structure 131 and the second lead-out structure 132 are electrically connected to the first conductive layer 111 and the second conductive layer 113, respectively. The first lead-out structure 131 and the second lead-out structure 132 have a height difference in the thickness direction of the electrochromic film 110.

[0038] Furthermore, such as Figure 3a As shown, in one embodiment, a first lead-out structure 131 and a second lead-out structure 132 are disposed approximately on the left and right sides in the direction parallel to the electrochromic film 110. The projections of the first lead-out structure 131 and the second lead-out structure 132 do not overlap along the thickness direction of the electrochromic film 110.

[0039] The first lead-out structure 131 and the second lead-out structure 132 are staggered in two directions, which is beneficial to achieve electrical insulation isolation between the first lead-out structure 131 and the second lead-out structure 132, and provides a larger operating space between the first lead-out structure 131 and the second lead-out structure 132, which facilitates the connection between the first lead-out structure 131 and the second lead-out structure 132 and the lead-out circuit board 120.

[0040] It is understandable that the first lead-out structure 131 and the second lead-out structure 132 are staggered. If the two lead-out structures are directly connected to external power supply equipment or control equipment, the connection will be difficult and inconvenient.

[0041] In response to the above problems, such as Figure 3a and Figure 4 As shown, the first electrical connection terminal 121 and the second electrical connection terminal 122 are spaced apart and insulated from each other. The first electrical connection terminal 121 is electrically connected to the first lead-out structure 131 through internal traces (such as vias) and surface traces of the lead-out circuit board 120. The second electrical connection terminal 122 is electrically connected to the second lead-out structure 132 through internal traces (such as vias) and surface traces of the lead-out circuit board 120. Thus, the electrochromic film 110 can receive electrical energy provided by external devices through the first electrical connection terminal 121 and the second electrical connection terminal 122 to regulate the transmittance of the electrochromic film 110.

[0042] In this embodiment, the first electrical connection terminal 121 and the second electrical connection terminal 122 are disposed on the first surface 126 of the lead-out circuit board 120. By concentrating the first electrical connection terminal 121 and the second electrical connection terminal 122 on the first surface 126 of the lead-out circuit board 120, the relative positions between the first electrical connection terminal 121 and the second electrical connection terminal 122 can be set according to the interface of the external device, which simplifies the docking operation between the lead-out circuit board 120 and the external device and improves the convenience and reliability of the electrical connection.

[0043] In one embodiment, the lead-out circuit board is a PCB board or an FPC board. In another embodiment, the lead-out circuit board is a multilayer PCB board.

[0044] In some embodiments, the lead-out circuit board 120 further includes a second surface 127, which is disposed opposite to the first surface 126 along the thickness direction of the electrochromic film 110. For example... Figure 1 and Figure 2 As shown, the first surface 126 is the surface of the lead-out circuit board 120 facing the first conductive layer 111, and the second surface 127 is the surface of the lead-out circuit board facing the second conductive layer 113.

[0045] In this embodiment, the first lead-out structure 131 and the second lead-out structure 132 are respectively fixed to the first surface 126 and the second surface 127 of the lead-out circuit board 120. The first lead-out structure 131 is connected to the adjacent first surface 126, and the second lead-out structure 132 is connected to the adjacent second surface 127. Shortening the connection length between the first lead-out structure 131 and the lead-out circuit board 120, as well as the connection length between the second lead-out structure 132 and the lead-out circuit board 120, helps to reduce resistance and standardize wiring. Furthermore, the connection between the first lead-out structure 131 and the lead-out circuit board 120 requires no bending or only a minimal bending, and the connection between the second lead-out structure 132 and the lead-out circuit board 120 requires no bending or only a minimal bending, improving connection reliability.

[0046] In one embodiment, the distance between the first surface 126 and the second surface 127 (i.e., the thickness of the lead-out circuit board 120) is equal to the distance between the first lead-out structure 131 and the second lead-out structure 132. The first surface 126 and the surface of the first lead-out structure 131 adjacent to the first surface 126 are located on the same plane, and the second surface 127 and the surface of the second lead-out structure 132 adjacent to the second surface 127 are located on the same plane. When the first lead-out structure 131 is connected to the lead-out circuit board 120, no bending is required, and when the second lead-out structure 132 is connected to the lead-out circuit board 120, no bending is required, thus improving the connection reliability.

[0047] In one embodiment, the distance between the first surface 126 and the second surface 127 (i.e., the thickness of the lead-out circuit board 120) is smaller than the distance between the first lead-out structure 131 and the second lead-out structure 132. The gap between the first surface 126 and the first lead-out structure 131 can be filled with conductive adhesive, and the gap between the second surface 127 and the second lead-out structure 132 can also be filled with conductive adhesive. The conductive adhesive enables the electrical connection between the lead-out structure and the lead-out circuit board 120, and makes it possible for the first lead-out structure 131 to be connected to the lead-out circuit board 120 without bending or with minimal bending, and for the second lead-out structure 132 to be connected to the lead-out circuit board 120 without bending or with minimal bending, thereby improving the connection reliability.

[0048] In some embodiments, the first electrical connection terminal 121 and the second electrical connection terminal 122 protrude from the first surface 126.

[0049] In one embodiment, the first electrical connection terminal 121 and the second electrical connection terminal 122 are protruding from the first surface 126 using a metal probe structure. The first electrical connection terminal 121 and the second electrical connection terminal 122 are metal electrical connection terminals, such as any one of RJ45, USB, Type-C, or spring pin connection terminals.

[0050] Correspondingly, the external power supply equipment is equipped with a metal sleeve, and a metal probe is inserted into the metal sleeve to form an electrical connection. The first electrical connection terminal 121 and the second electrical connection terminal 122 protrude from the first surface 126, improving the efficiency and convenience of connecting the first electrical connection terminal 121 and the second electrical connection terminal 122 to the external equipment.

[0051] In other embodiments, the first electrical connection terminal 121 and the second electrical connection terminal 122 may also be two recesses formed on the first surface 126. The interface corresponding to the external device may be a probe, which is inserted into the recess to achieve electrical connection.

[0052] In some embodiments, such as Figure 4 As shown, the distance between the first electrical connection terminal 121 and the second electrical connection terminal 122 is less than the distance between the first lead-out structure 131 and the second lead-out structure 132.

[0053] By reducing the distance between the first electrical connection terminal 121 and the second electrical connection terminal 122, the electrical connection area between the lead-out circuit board 120 and the external device is centrally arranged, which improves the convenience of electrical connection and facilitates the sealing and isolation of the electrical connection area.

[0054] In addition, increasing the spacing between the first lead-out structure 131 and the second lead-out structure 132 can provide a larger operating space, which facilitates the electrical connection of the first lead-out structure 131 with the lead-out circuit board 120 and the first conductive layer 111, and facilitates the electrical connection of the second lead-out structure 132 with the lead-out circuit board 120 and the second conductive layer 113, thereby improving connection efficiency and connection reliability.

[0055] In some embodiments, the first lead-out structure 131 and the second lead-out structure 132 are spaced apart along the outer contour of the electrochromic film 110, and the first electrical connection terminal 121 and the second electrical connection terminal 122 are arranged between the first lead-out structure 131 and the second lead-out structure 132. Exemplarily, the projections of the first lead-out structure 131, the first electrical connection terminal 121, the second electrical connection terminal 122, and the second lead-out structure 132 onto the lead-out circuit board 120 are sequentially spaced apart. Alternatively, the projections of the second lead-out structure 132, the first electrical connection terminal 121, the second electrical connection terminal 122, and the first lead-out structure 131 onto the lead-out circuit board 120 may be sequentially spaced apart (e.g., ...). Figure 4 ).

[0056] See Figure 4Thus, the first lead-out structure 131 and the second lead-out structure 132 are spaced apart along the thickness direction of the electrochromic film 110. Furthermore, the first lead-out structure 131 and the second lead-out structure 132 are also spaced apart along the outer contour of the electrochromic film 110. The relatively large distance between the first lead-out structure 131 and the second lead-out structure 132 along the outer contour of the electrochromic film 110 is beneficial for improving the connection efficiency and reliability between the lead-out structures and the conductive layer and the lead-out circuit board 120. like Figure 4 As shown, the first electrical connection terminal 121 and the second electrical connection terminal 122 are located between the first lead-out structure 131 and the second lead-out structure 132, making the structure compact and reducing the overall size of the lead-out circuit board 120 and the electrochromic film 110. In addition, the small distance between the first electrical connection terminal 121 and the second electrical connection terminal 122 is beneficial to improving the convenience of electrical connection between the lead-out circuit board 120 and external devices, and also facilitates the sealing and isolation of the electrical connection area.

[0057] In existing technologies, the color change of electrochromic devices is achieved by applying specific driving parameters (including voltage, current, and duration). Due to differences in material composition and structure, different colors of electrochromic devices often require different driving parameters to achieve optimal color-changing effects. For example, blue and green electrochromic devices require different driving voltages, and even devices of the same color may have different control parameters. This difference necessitates that manufacturers develop dedicated driving circuits and control systems for each color or model of electrochromic device in practical applications.

[0058] Current electrochromic product driving solutions typically employ a one-to-one correspondence, meaning each color or model of device is equipped with a specially designed driver. While this design ensures optimal performance for each color and model, it also introduces complexity into product maintenance. When a product line includes multiple colors and models, maintaining inventory of multiple drivers is necessary, increasing costs.

[0059] In response to the above problems, such as Figure 1 and Figure 2 As shown, the lead-out circuit board 120 of this application also includes an identification element 125 and a first signal connection terminal 123 and a second signal connection terminal 124 that are communicatively connected to the identification element 125. The first signal connection terminal 123 and the second signal connection terminal 124 are spaced apart and insulated from each other.

[0060] The identification element 125 communicates with an external control device through the first signal connection terminal 123 and the second signal connection terminal 124 to determine the control logic for regulating the transmittance of the electrochromic film 110.

[0061] In some embodiments, an external control device reads the information carried by the identification element 125 through the first signal connection terminal 123 and the second signal connection terminal 124, determines the control logic based on the read information, and adjusts the transmittance of the electrochromic film 110 according to the control logic, so that an external control device can identify and adapt to multiple models of electrochromic devices 100, thereby reducing the maintenance cost of the electrochromic devices 100.

[0062] The identification element 125 can be any of the following: a resistor, a capacitor, an inductor, or a chip. The external control device receives the electrical signal transmitted by the resistor, capacitor, inductor, or chip to invoke the corresponding control logic. Alternatively, the identification element 125 stores identification information, and the external control device reads the identification information to invoke the corresponding control logic.

[0063] For example, the identification element 125 stores the color information and maximum capacity value of the electrochromic film 110. When the external control device obtains the information stored on the identification element 125 that the electrochromic film 110 is green, it calls the control logic corresponding to green and outputs the control voltage and capacity corresponding to the electrochromic film 110.

[0064] In one embodiment, the first signal connection terminal 123 and the second signal connection terminal 124 adopt a metal probe structure, such as an M-series circular connector, an SMA RF connector, an RJ45 connector, a USB connector, a Type-C connector, or a spring pin connector.

[0065] External control devices are equipped with corresponding metal sleeves, and metal probes are inserted into the metal sleeves to form signal connections. This flexible contact plug-and-play structure is suitable for frequent plugging and unplugging, extending service life.

[0066] In some embodiments, both the first signal connection terminal 123 and the second signal connection terminal 124 are disposed on the first surface 126.

[0067] The first signal connection terminal 123 and the second signal connection terminal 124 protrude from the first surface 126, facilitating quick communication connection with external devices.

[0068] Furthermore, the first electrical connection terminal 121, the second electrical connection terminal 122, the first signal connection terminal 123, and the second signal connection terminal 124 are arranged side by side at intervals on the first surface 126, thereby concentrating the two electrical connection terminals and the two signal connection terminals to improve the insertion efficiency and connection stability of the lead-out circuit board 120 and external devices.

[0069] In one embodiment, such as Figure 5As shown, the first electrical connection terminal 121, the second electrical connection terminal 122, the first signal connection terminal 123, and the second signal connection terminal 124 are arranged sequentially at intervals. The centralized arrangement of these terminals improves the insertion efficiency and connection stability between the lead-out circuit board 120 and external devices. Furthermore, the sequential arrangement of the first electrical connection terminal 121, the second electrical connection terminal 122, the first signal connection terminal 123, and the second signal connection terminal 124 along the outer contour of the electrochromic film 110 helps to reduce the overall size of the lead-out circuit board 120 and the electrochromic film 110.

[0070] In another embodiment, the first signal connection terminal 123 and the second signal connection terminal 124 are arranged between the first electrical connection terminal 121 and the second electrical connection terminal 122. In another embodiment, as... Figure 6 As shown, the first electrical connection terminal 121 and the second electrical connection terminal 122 are arranged between the first signal connection terminal 123 and the second signal connection terminal 124.

[0071] In some embodiments, the lead-out circuit board 120 and the identification element 125 are integrated. The identification element 125 is communicatively connected to the first signal connection terminal 123 and the second signal connection terminal 124 through the communication lines of the lead-out circuit board 120.

[0072] In some embodiments, such as Figure 1 The lead-out circuit board 120 and the identification element 125 are separately configured. The identification element 125 is fixed to the first surface 126. For example, the identification element 125 is fixed to the first surface 126 of the lead-out circuit board 120 by adhesive bonding, or the identification element 125 is bonded to the insulating layer of the lead-out circuit board 120. By making reasonable use of the space of the lead-out circuit board 120, its structure is made compact, the volume of the conductive circuit board is reduced, and the electrochromic device 100 of this application is suitable for miniaturized, high-density, and high-reliability electronic equipment applications.

[0073] This application also provides electrochromic glasses, including a frame assembly 200 and a lens assembly 300.

[0074] like Figure 7 As shown, the eyeglass frame assembly 200 includes an eyeglass frame 210, and the first side 211 of the eyeglass frame 210 includes two electrical connection ports 2111.

[0075] like Figure 8 As shown, the lens assembly 300 includes a lens frame 310 and an electrochromic device 100 as described in any of the foregoing embodiments, the electrochromic device 100 being fixed to the lens frame 310.

[0076] The first electrical connection terminal 121 and the second electrical connection terminal 122 are disposed on the second side 311 of the lens frame 310. The second side 311 is used to fix with the first side 211. When the second side 311 is fixedly connected with the first side 211, the first electrical connection terminal 121 and the second electrical connection terminal 122 are respectively inserted into the two electrical connection ports 2111.

[0077] like Figure 7 and Figure 8 As shown, the first side 211 of the eyeglass frame 210 also includes two signal connection ports 2112, and the first signal connection terminal 123 and the second signal connection terminal 124 are disposed on the second side 311 of the lens frame 310. The first electrical connection terminal 121, the second electrical connection terminal 122, the first signal connection terminal 123 and the second signal connection terminal 124 protrude from the second side 311 toward the first side 211.

[0078] When the second side 311 is fixedly connected to the first side 211, the first signal connection terminal 123 and the second signal connection terminal 124 are respectively plugged into the two signal connection ports 2112.

[0079] The electrochromic glasses of this application improve the convenience and reliability of the docking operation between the lens frame 310 and the frame frame 210 by concentrating the first electrical connection terminal 121, the second electrical connection terminal 122, the first signal connection terminal 123, and the second signal connection terminal 124 on the second side 311. Simultaneously, the first lead-out structure 131 and the second lead-out structure 132 in the electrochromic device 100 are respectively connected to the two surfaces of the lead-out circuit board 120 without bending, thus improving the product quality of the electrochromic device 100 and extending the service life of the electrochromic glasses.

[0080] In some embodiments, such as Figure 9 The frame assembly 200 also includes a wearable component (not shown) and a controller 220 fixed to the wearable component. The wearable component is fixedly connected to the frame frame 210. The wearable component is used to wear the electrochromic glasses to the user. The controller 220 is electrically connected to two electrical connection ports 2111.

[0081] The lead-out circuit board 120 of the electrochromic device 100 also includes an identification element 125. The identification element 125 is used for communication connection with the controller 220.

[0082] The controller 220 is used to read the identification information of the electrochromic film 110 stored in the identification element 125, and to determine the control logic based on the identification information. It also adjusts the transmittance of the electrochromic film 110 according to the control logic through two electrical connection ports 2111, the first electrical connection terminal 121, and the second electrical connection terminal 122. In this way, the identification element 125 feeds back the model information (control logic) of the lens assembly 300 to the controller 220 through the second signal connection terminal 124 and the first signal connection terminal. The controller 220 adjusts the transmittance of the electrochromic lens film according to the received signal information (control logic), enabling a single frame assembly 200 to identify and adapt to multiple colors of electrochromic films 110 (lens assembly 300), thus reducing the maintenance cost of electrochromic glasses.

[0083] In one embodiment, the frame assembly 200 also includes a power source. The power source is attached to the wearable device and is used to power the controller 220.
