[0031] Figures 1 to 6 FIG. 1 shows a mirror assembly 101 according to an embodiment of the present invention. Figure 1 and Figure 2As shown, the mirror assembly 101 includes a lens 102, an electric control box 104, a circuit board 111 and an elastic member 110. The lens 102 of the present invention refers to a reflector, not a lens. Figure 1 As shown, the back surface 103 of the lens 102 is the back surface of the lens 102, and the front surface of the lens 102 is the front surface of the lens 102. Figure 3 As shown, the electric control box 104 is connected to the back surface 103 of the lens 102, and the electric control box 104 and the back surface 103 together define a mounting cavity 114, and the circuit board 111 and the elastic member 110 are both arranged in the mounting cavity 114. Figure 2 As shown, the circuit board 111 includes a substrate 124 and a capacitive touch sensor 112. The substrate 124 is a PCB (Printed Circuit Board). The substrate 124 includes a mounting surface 125. The capacitive touch sensor 112 is connected to the mounting surface 125. In this embodiment, the mounting surface 125 is the front surface of the substrate 124 (e.g., Figure 2 As shown in FIG), the mounting surface 125 faces the back surface 103 of the lens 102. Figure 3 As shown, the electric control box 104 and the circuit board 111 are both connected to the elastic member 110 , and the elastic force of the elastic member 110 is used to keep the capacitive touch sensor 112 in contact with the back surface 103 of the lens 102 .

[0032] The present invention is equivalent to pressing the circuit board 111 against the back surface 103 of the lens 102 through the elastic member 110, so that the capacitive touch sensor 112 is tightly fitted to the back surface 103 of the lens 102, ensuring the accuracy of the capacitive touch sensor 112 in detecting the user's touch action. Since the elastic member 110 itself is elastic, even if there is a dimensional error between the circuit board 111 and the housing due to processing and manufacturing reasons, the elastic member 110 can also adaptively deform to adapt to the error, thereby pressing the circuit board 111 against the back surface 103 of the lens 102. That is, the present application does not directly use the housing to press the circuit board 111, avoiding the problem that the capacitive touch sensor 112 cannot be pressed against the back surface 103 of the lens 102 due to the dimensional error between the housing and the circuit board 111. In addition, the present invention uses the elastic member 110 to press the circuit board 111, which is also conducive to reducing the risk of damage to the circuit board 111.

[0033] like Figure 6As shown, in some embodiments, the substrate 124 further includes a first abutting surface 121. The first abutting surface 121 and the mounting surface 125 are disposed opposite each other. If the mounting surface 125 is the front surface of the substrate 124, the first abutting surface 121 is the rear surface of the substrate 124. The electrical control box 104 includes a second abutting surface 122, which can be located on the cover 106 of the electrical control box 104. The second abutting surface 122 is a portion of the wall of the mounting cavity 114 and is disposed opposite the first abutting surface 121. The ends of the elastic member 110 abut the first abutting surface 121 and the second abutting surface 122, respectively. When the elastic member 110 is in a compressed state, the elastic force of the elastic member 110 causes the first abutting surface 121 and the second abutting surface 122 to move away from each other, thereby enabling the elastic member 110 to press the capacitive touch sensor 112 against the back surface 103 of the lens 102. Furthermore, since the elastic member 110 abuts against the cover 106 and the substrate 124 , the mirror assembly 101 has a simple structure and low cost, and the assembly of the elastic member 110 , the cover 106 and the circuit board 111 is convenient.

[0034] Since the elastic member 110 contacts the substrate 124, the elastic member 110 may be configured as an insulator to prevent the substrate 124 from short-circuiting due to contact with the elastic member 110. More specifically, the elastic member 110 may be made of foam, rubber, or other materials that are both elastic and insulating. In some embodiments, in order to reduce the shape complexity and manufacturing difficulty of the elastic member 110, the elastic member 110 may be cylindrical. For example, Figure 2 In the embodiment shown, the elastic member 110 is cylindrical. In other embodiments not shown, the elastic member 110 may be in the shape of a polygonal prism (eg, a quadrangular prism, a hexagonal prism, etc.).

[0035] like Figure 6 As shown, in some embodiments, the electrical control box 104 further includes a positioning rib 107, which is connected to the second abutting surface 122. The positioning rib 107 protrudes relative to the second abutting surface 122, so that the positioning rib 107 and the second abutting surface 122 jointly define a positioning groove 123. One end of the elastic member 110 is disposed in the positioning groove 123, and the positioning rib 107 surrounds the elastic member 110. The positioning groove 123 is used to position the elastic member 110, making it convenient for the user to install the elastic member 110 and preventing the elastic member 110 from deviating from its original position during use. The shape of the positioning rib 107 is adapted to the shape of the elastic member 110. For example, when the elastic member 110 is cylindrical, the positioning rib 107 is in the shape of a circular ring; if the elastic member 110 is in the shape of a quadrangular prism, the positioning rib 107 is in the shape of a rectangular frame.

[0036] In some embodiments, the housing 106 further includes a positioning post 128 (e.g., Figure 4As shown, positioning holes (not shown) are provided at the corners of the substrate 124. Positioning posts 128 are provided through the positioning holes to achieve positioning between the cover body 106 and the substrate 124.

[0037] Please combine Figure 2 and Figure 3 In some embodiments, the electric control box 104 includes a frame 113 and a cover 106. To reduce costs, the frame 113 and the cover 106 can be made of plastic. The frame 113 is bonded to the back surface 103 of the lens 102, and the cover 106 is connected to the frame 113 by screws 105. The cover 106 is connected to the side of the frame 113 that faces away from the back surface 103 of the lens 102. Figure 2 As shown, the cover 106 is also provided with a threading hole 109, through which the wires used to connect to the circuit board 111 can pass. When the user repairs the circuit board 111, the user can first remove the screws 105, then remove the cover 106, and then take out the circuit board 111, while the frame 113 can remain on the back side 103 of the lens 102. The frame 113 does not need to be frequently disassembled. The frame 113 is fixed to the lens 102 by bonding rather than screwing. This can save the operation of drilling holes in the back side 103 of the lens 102, making it easier for the user to install the frame 113 and avoid damaging the lens 102 during drilling. The cover 106 and the frame 113 are connected by screws 105 instead of bonding, making it easier for the user to remove and install the cover 106 multiple times. Specifically, if the cover 106 and the frame 113 are fixed by gluing, then after the cover 106 is removed, the adhesive strength of the glue or tape between the cover 106 and the frame 113 will inevitably decrease, causing the cover 106 to easily fall off during subsequent use. If the glue or tape is reapplied after each removal of the cover 106, the user will need to clean the glue or tape remaining on the cover 106 or the frame 113 first, which will greatly reduce the ease of installation of the cover 106. Therefore, in this embodiment, the cover 106 and the frame 113 are connected by screws 105, thereby improving the ease of installation of the cover 106.

[0038] In other embodiments, to improve the ease of installation of the cover 106, the cover 106 and the frame 113 may not be connected by screws 105. Alternatively, the cover 106 and the frame 113 may be connected by snapping, magnetic connection, or the like, as long as the cover 106 and the frame 113 are connected by a detachable connection method other than bonding. If the cover 106 and the frame 113 are snap-fitted, buckles need to be provided on the cover 106 and the frame 113; if the cover 106 and the frame 113 are snap-fitted, magnets need to be installed on the cover 106 and the frame 113.

[0039] like Figure 4As shown, the frame 113 has a sealing groove 115. The sealing groove 115 is located on the side of the frame 113 facing away from the back surface 103 of the lens 102. The sealing groove 115 surrounds the circuit board 111, and a portion of the cover 106 is disposed within the sealing groove 115. This arrangement can improve the sealing performance at the connection between the cover 106 and the frame 113, reduce the risk of water from the external environment entering the interior of the electric control box 104, and thus reduce the risk of short circuiting the circuit board 111.

[0040] In some embodiments, the shape of the frame 113 is as follows: Figure 5 As shown, the frame 113 includes a main body 120, a first rib 118, and a second rib 119. The main body 120 is bonded to the back surface 103. The first rib 118 and the second rib 119 are both connected to the side surface of the main body 120 facing away from the lens 102. The first rib 118 and the second rib 119 both protrude relative to the main body 120 and surround the circuit board 111. The second rib 119 is arranged at intervals around the periphery of the first rib 118. The first rib 118, the second rib 119, and the main body 120 together define a sealing groove 115. With the above arrangement, a deeper sealing groove 115 can be formed without making the main body 120 too thick, which helps reduce the thickness of the main body 120.

[0041] like Figure 4 and Figure 5 As shown, the frame 113 is further provided with a groove 116. Groove 116 can be provided on a side surface of the main body 120 facing the lens 102, with the back side 103 of the lens 102 covering the groove 116. The mirror assembly 101 also includes an adhesive (not shown) housed within the groove 116. The back side 103 and the groove walls of the groove 116 are bonded to the adhesive, thereby bonding and fixing the frame 113 and the back side 103 of the lens 102 to each other. The adhesive can specifically be a double-sided tape, adhesive, etc. The groove 116 can be used to position the adhesive, thereby assisting the user in correctly placing the double-sided tape or adhesive on the frame 113. In addition, the shape of the adhesive matches that of the groove 116, and the adhesive is also frame-shaped. The adhesive and the groove 116 both surround the circuit board 111. Since the adhesive surrounds the circuit board 111 , the adhesive can also act as a seal to prevent water from entering the interior of the electric control box 104 through the gap between the frame 113 and the back surface 103 , thereby reducing the risk of short circuiting the circuit board 111 .

[0042] In some embodiments, the circuit board 111 and the electric control box 104 satisfy the following conditions: a portion of the orthographic projection of the substrate 124 can fall on the side surface of the main body 120 facing away from the lens 102, and the sealing groove 115 is arranged on the periphery of the orthographic projection. This arrangement can improve the structural compactness of the mirror assembly 101 and reduce the space occupied by the electric control box 104. Specifically, the orthographic projection of the substrate 124 refers to the projection of the substrate 124 along the inner normal of the back surface 103 of the lens 102. Figure 4 For example, the back surface 103 of the lens 102 is a plane, and the inner normal of the back surface 103 of the lens 102 is from the back to the front (the outer normal is from the front to the back), and the projection of the substrate 124 from the back to the front is the orthographic projection of the substrate 124. Because the outer edge 126 of the substrate 124 extends beyond the inner edge 127 of the main body 120, a portion of the projection of the substrate 124 from the back to the front can fall on the main body 120. More specifically, as Figure 4 As shown, the portion of the orthographic projection of the substrate 124 between the dotted line L1 and the dotted line L2 can fall on the surface of the main body 120 facing away from the lens 102. Since a portion of the substrate 124 can fall on the surface of the main body 120 facing away from the lens 102, the distance between the outer edge 126 of the substrate 124 and the inner wall of the cover 106 is smaller, and the arrangement of the substrate 124 and the cover 106 is more compact, which helps to reduce the space occupied by the electric control box 104.

[0043] When the cover 106 and the frame 113 are connected by screws 105, the cover 106 is provided with a first connection hole 108 (such as Figure 2 As shown, the second rib 119 of the frame 113 is provided with a second connection hole 117 (as shown Figure 5 As shown in FIG, the first connecting hole 108 is a through hole, the second connecting hole 117 is a blind hole, and the screw 105 passes through the first connecting hole 108 and the second connecting hole 117. Figure 5 As shown, the protruding distance of the second rib 119 relative to the main body 120 (i.e., the length of the second rib 119 in the front-to-rear direction) is greater than the protruding distance of the first rib 118 relative to the main body 120, so that the second connecting hole 117 has sufficient depth to ensure the firmness of the connection between the screw 105 and the frame 113.

[0044] The present invention also provides a mirror cabinet 201, which includes the mirror assembly 101 in any of the above embodiments. Figure 7As shown, mirror cabinet 201 includes a cabinet body 202 and a cabinet door 203. Cabinet door 203 includes a door frame and the aforementioned mirror assembly 101, with lens 102 mounted on the door frame. Door 203 is connected to cabinet body 202 via a hinge. When door 203 is closed, the front face of lens 102 is located outside cabinet body 202, while the back face 103 of lens 102 faces inside cabinet body 202. An electrical control box 104 is located inside cabinet body 202. The front face of lens 102 is also provided with several button patterns 204. The positions of button patterns 204 correspond to the positions of capacitive touch sensors 112. When a user's finger touches a button pattern 204, the state of mirror cabinet 201 can be changed. For example, mirror cabinet 201 also includes a light (not shown). The circuit board 111 within electrical control box 104 is connected to the light of mirror cabinet 201 via a wire. When a user touches a button pattern 204, the light of mirror cabinet 201 can be turned on. For another example, the mirror cabinet 201 further includes an electric heating device. The circuit board 111 is connected to the electric heating device (not shown) via a wire. When the user touches the button pattern 204 , the electric heating device can be turned on. The electric heating device heats the lens 102 to defog the lens 102 .
