Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The present disclosure provides a mirror with a built-in display screen function, as shown in fig. 1 and 2, the mirror specifically includes a first lens 1, a second lens 2, and an accommodating layer 3 located between the first lens 1 and the second lens 2, a display component 4 and a light source guiding part 5 are provided on the accommodating layer 3, at least one end of the light source guiding part 5 is provided with a first bright portion, the display component 4 is electrically connected to a control board 7 through a connecting element 6, the control board 7 is in contact with the surface of the second lens 2 or the accommodating layer 3 through a heat dissipation part 8, and the first bright portion is in contact with a hollow layer facing the second lens 2 or the accommodating layer 3 through a light source heat dissipation fin.

The heat dissipation part 8 and the light source heat dissipation plate may be directly connected to the second lens 2 or the first lens 1, or may be indirectly connected. The heat dissipation part 8 and the light source heat dissipation fins are both arranged in a horizontal structure, and high-heat-conduction insulating materials can be filled between contact surfaces between the heat dissipation part 8 and the light source heat dissipation fins for eliminating air gaps between the adjacent control plate 7 and the heat dissipation part 8 and between the first lens 1 and the second lens 2, so that the heat conduction speed is improved, and vibration energy is absorbed.

The first lighting part includes a second lighting part 9 provided at a lower edge of the light source delivering part 5, and the second lighting part 9 is provided with a heat radiating part 10. Considering that the mirror may be directly heated from the outside and may be in direct contact with the external space, it is feared that it is difficult to exhibit the heat dissipation effect at a high temperature. And the mirror body only contacts with the user, and the display screen can be used only when a person is in the room.

The heat emitting part 10 includes a first connection part 11, a second connection part 12, and a third connection part 13 surrounding the control board 7, the first connection part 11 and the third connection part 13 are respectively located at left and right edges of the control board 7, and the second connection part 12 is located between the second lighting part 9 and the control board 7.

In order to avoid that the opaque control panel 7 forms a shield outside the display area, which would affect the user's view, the control panel 7 must be placed under the display area, which results in that the main heat generating components, i.e. the electronic components, the chip on the control panel 7 and the second illumination portion 9 are located at three positions at different heights with respect to the first face of the second lens 2. Where the electronic components on the control board 7 are closest to the first side of the second lens 2 and the chip is slightly further away from the first side of the second lens 2. The second illumination portion 9 is located on the side of the display screen remote from the second lens 2, furthest from the first face of the second lens 2.

The above various heating components are not only at different heights relative to the first surface of the second lens 2, but also have a certain distance in the horizontal position, and are dispersed in each position.

The second lens 2 has a first surface facing the hollow layer, the first surface of the second lens 2 is provided with the display component 4 and the light source guiding and transmitting part 5, and the display component 4 is positioned between the second lens 2 and the light source guiding and transmitting part 5.

The control board 7 is connected to the first surface of the second lens 2 through a heat dissipation part 8, and the first light part is connected to the first surface of the second lens 2 through a light source heat dissipation plate.

The first lighting part comprises a first lighting part 14 arranged on the light source guiding part 5, a first radiating block 15 is arranged on the first lighting part 14, the first radiating block 15 is connected with the first lighting part 14 through first heat-conducting silica gel, and the first radiating block 15 is connected with the second lens 2 through a second heat-conducting silica gel 17;

the upper edge of the heat dissipation part 10 is connected with the second illumination part 9 through a third heat-conducting silica gel 18, and the heat dissipation part 10 is connected with the second lens 2 through a fourth heat-conducting silica gel 19.

The heat generating components in the transparent liquid crystal display mirror body comprise the control board 7, the second illumination portion 9 above and the connecting element 6 of the display module 4. Because the heating components are respectively positioned at the upper side and the lower side of the control panel 7, the control panel 7 is in a long strip shape, the width is slightly shorter than that of the display assembly 4, the connecting elements 6 are connected between the control panel 7 and the display assembly 4 at intervals, and if a heat dissipation plate and the above three components positioned at different positions are required to be in good contact for heat dissipation, the heat dissipation plate must have a more complex three-dimensional structure. The heat dissipation plate with the structure has higher requirements on processing difficulty and precision, and higher processing cost is bound to be caused.

The display module 4 and the control panel 7 are attached to the first surface of the second lens 2, the electronic component of the control panel 7 is an integrated circuit chip, the thickness of the control panel 7 is 2-7mm, and the thickness of the control panel 7 is generally larger than that of the liquid crystal display, so that the heat radiating portion 10 opposite to the second illuminating portion 9 interferes with the control panel 7, in order to avoid interference and ensure a sufficiently large heat radiating area, the heat radiating portion 10 is designed to be in a ring-shaped horizontal structure, the bottom surface area of the heat radiating portion 10 is 100-500 cm2, and the thickness is 4-6 mm.

The heat dissipation part 10 arranged opposite to the lower edge of the second illumination part 9 and the heat dissipation part 8 arranged opposite to the surface of the circuit board, where the electronic elements are arranged, are used for dissipating heat of the electronic elements on the illumination part and the control board 7 respectively, the flexible connecting element 6 is clamped between the heat dissipation part and the control board, and the heat dissipation part and the control board are clamped through a driving chip on the heat-conducting silica gel to form an integrated structure. The structure has the characteristics of easy processing, convenient assembly, lower cost, capability of absorbing vibration energy and good heat dissipation effect. And only the non-interference local area of the second illumination unit 9 can be radiated. According to the invention, the upper edge of the heat radiating part 10 is arranged opposite to the lower edge of the second lighting part 9, so that the heat radiating part 10 can be contacted with the whole surface of the second lighting part 9 for radiating heat, and the heat radiating efficiency is improved.

The main heating elements such as the control plate 7, the first illumination part 14 and the second illumination part 9 form good thermal contact with the area as large as possible between the heat dissipation part 8 and the lens, and the heat is dissipated to the inside in a physical contact mode, so that the heat dissipation efficiency is improved, and good heat dissipation is realized in a narrow closed space.
