[0035] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0036] According to one aspect of the present application, this embodiment discloses an optical reading and writing device with heat dissipation function. Figures 1 to 7As shown, in this embodiment, an optical reading / writing device with heat dissipation function includes an auxiliary device body 1. The auxiliary device body 1 includes a housing 11 having a first opening 111 and a second opening 112 formed on the side and bottom surfaces, respectively; an optical lens; a lighting assembly 13; and a heat sink 14. The bottom surface of the housing 11 is provided with a groove at an edge corresponding to the second opening 112, and at least a portion of the lighting assembly 13 is accommodated in the groove. The heat sink 14 is fixed to the side surface of the housing 11, and the groove is formed with at least one strip-shaped opening near the side surface of the heat sink 14. At least a portion of the heat sink 14 extends into the groove through the strip-shaped opening.

[0037] It should be noted that if Figure 1 and Figure 2 As shown, the reading content that the user needs to read can be placed directly below the second opening 112 of the auxiliary device body 1. The user looks directly at the first opening 111 of the housing 11 and sees the reading content below the second opening 112 through the optical lens in the auxiliary device body 1, avoiding the inconvenience of the user having to lower their head to read. The optical lens of the present application can transmit light reflected from the reading content to the user's eyes to achieve the user's reading purpose. The optical lens can adopt existing lenses or lens combinations. Those skilled in the art can select optical lenses according to their needs. This is a conventional technical means in this field and is not limited by this application.

[0038] The optical reading / writing device of the present application is provided with an illumination assembly 13 on the bottom surface of the housing 11 to illuminate the content the user is reading, thereby increasing the brightness when the user is reading and reducing eye fatigue. However, the illumination assembly 13 generates a large amount of heat during prolonged use. This heat exposure to the optical reading / writing device may damage the device. The present application is provided with a heat sink 14, at least a portion of which is disposed in a groove and in contact with the illumination assembly 13. This allows the heat sink 14 to absorb the heat generated by the illumination assembly 13 in the groove through contact heat conduction and conduct it to the outside of the optical reading / writing device, thereby reducing the temperature of the illumination assembly 13, preventing damage to the optical reading / writing device, particularly the illumination assembly 13, and extending the service life of the optical reading / writing device.

[0039] It should be noted that the lighting assembly 13 can be selected from existing compatible lighting assemblies 13 based on the shape of the groove, and this application is not limited to this. In a specific example, the bottom surface of the housing 11 of this application is formed with an annular groove surrounding the second opening 112. Optionally, a fixing member 20 can be provided on the bottom surface of the housing 11, and the fixing member 20 is formed with an annular groove to secure the lighting assembly 13 in the groove of the fixing member 20.

[0040] To fit the groove, e.g. Figure 3As shown, the lighting assembly 13 in this specific example includes a plurality of strip light strips, which provide lighting for the user's reading content.

[0041] Among them, it can be understood that the width of the strip light strip is smaller than the width of the groove, then the strip light strip can be fixed as a whole on the bottom surface of the groove, and the bottom surface of the strip light strip and the bottom surface of the groove are fixedly arranged to achieve the purpose of fixing the strip light strip in the groove, and the light emitted by the light strip can illuminate the reading content below the second opening 112, thereby achieving the purpose of supplementary lighting of the reading content through the lighting component 13.

[0042] It should be noted that the lighting assembly 13 of the present application may also include a power supply for supplying power to the strip light strip and a control switch for turning the strip light strip on and off. Those skilled in the art may configure the specific structure and placement of the other components of the lighting assembly 13 according to actual needs. This is a conventional technical means in the art and is not limited in this application.

[0043] At least one strip-shaped opening is formed on a side of the groove close to the heat sink 14 , and at least a portion of the heat sink 14 extends into the groove through the strip-shaped opening.

[0044] Specifically, in order to improve the heat dissipation effect of the heat sink 14, the heat sink 14 can be made to contact the lighting assembly 13. In order to facilitate the contact between the heat sink 14 and the lighting strip, in this embodiment, at least one strip opening is opened on the outer side of the groove, so that the heat sink 14 can extend into the groove through the strip opening to contact the lighting assembly 13 over a larger range.

[0045] In an optional embodiment, if Figure 4 and Figure 5 As shown, a rectangular side 141 matching the width of the strip opening is formed at the bottom of the heat sink 14 , and at least a portion of the rectangular side 141 is bent and extends into the groove through the strip opening.

[0046] Specifically, it is understood that the heat sink 14 needs to absorb and dissipate the heat generated by the lighting assembly 13. Therefore, the bottom of the heat sink 14 forms a rectangular edge 141 that matches the width of the strip opening. The rectangular edge 141 is bent and extends through the strip opening into the groove to contact the lighting assembly 13, thereby absorbing the heat generated by the lighting assembly 13. The portion of the heat sink 14 connected to the rectangular edge 141 and fixed to the housing 11 outside the groove absorbs the heat absorbed by the rectangular edge 141 through heat conduction and dissipates it into the air, achieving the purpose of heat dissipation. The continuous heat conduction and heat dissipation of the heat sink 14 reduces the temperature of the lighting assembly 13.

[0047] In an optional embodiment, the heat sink 14 is disposed between the bottom surface of the groove and the lighting assembly 13 located in the groove.

[0048] Specifically, the heat sink 14 is arranged between the bottom surface of the groove and the lighting component 13. It can not only make large-scale contact with the lighting component 13 to improve the heat absorption effect, but also does not affect the lighting of the lighting component 13. The structure is simple and easy to set up. For example, when the heat sink 14 includes a rectangular edge 141, after the rectangular edge 141 is bent and extended into the groove through the strip opening on the side of the groove, the rectangular edge 141 extended into the groove can be inserted into the area between the lighting component 13 and the bottom surface of the groove where the temperature is the highest and the most difficult to dissipate heat, thereby absorbing a large amount of heat generated by the lighting component 13 that is difficult to dissipate, thereby improving the heat dissipation effect. The heat sink 14 has the characteristics of being thin in thickness and large in area. It can not only improve the heat dissipation effect through the large area, but also enable the low-thick heat sink 14 to be attached to the surface of the housing 11, avoiding excessive volume occupation and not having too much impact on the optical reading and writing device.

[0049] In an optional embodiment, the optical lens includes a curved mirror 122 and a semi-transparent and semi-reflective mirror 121, the housing 11 includes a first bracket 101 and a second bracket 102, the first bracket 101 includes a support frame side 18 with a top surface formed as an inclined surface and a back shell 15, the inclined surface is fixed with the semi-transparent and semi-reflective mirror 121, the second bracket 102 is fixed on the semi-transparent and semi-reflective mirror 121, the back shell 15 is opposite the first opening 111, the curved mirror 122 is provided on the back shell 15, the bottom of the support frame side 18 is formed with the groove, and the second bracket 102 is fixed to the optical lens. The support frame side 18 includes a fixed surface inclined toward the interior of the housing 11, and the heat sink 14 is fixed to the fixed surface.

[0050] When the optical reading and writing device is in use, the light reflected from the reading content below the second opening 112 is first reflected by the inclined semi-transparent and semi-reflective mirror 121 to the curved mirror 122 on the back shell 15. The curved mirror 122 diffuses the light and transmits it through the semi-transparent and semi-reflective mirror 121 to the user's eyes, thereby enabling the user to read the reading content of the first opening 111 through the second opening 112.

[0051] Optionally, a gasket 19 may be provided between the side surface 18 of the support frame and the back shell 15 to cushion the connection between the side surface 18 of the support frame and the back shell 15 .

[0052] In a specific example, the housing 11 is divided into a first bracket 101 and a second bracket 102. The first bracket 101 and the second bracket 102 form corresponding inclined surfaces, so that the semi-transparent and semi-reflective mirror 121 can be fixed on the first bracket 101 at an inclined angle. The upper surface of the semi-transparent and semi-reflective mirror 121 is further fixed to the second bracket 102, and the inclined surface of the second bracket 102 corresponding to the optical lens forms a first opening 111.

[0053] The side surface 18 of the support frame of the first bracket 101 surrounding the semi-transparent and semi-reflective mirror 121 is inclined toward the inside of the shell 11 to form a fixed surface. The fixed surface is inclined toward the inside of the shell 11 to leave space for the installation of the heat sink 14, thereby avoiding the problem of the overall volume of the optical reading and writing device with heat dissipation function becoming larger after the heat sink 14 is installed.

[0054] Optionally, the first bracket 101 and the second bracket 102 can be fixedly connected to the semi-transparent and semi-reflective mirror 121 by gluing, etc. Of course, in actual applications, the semi-transparent and semi-reflective mirror 121 can also be fixedly connected to the first bracket 101 and the second bracket 102 respectively by other means.

[0055] Of course, in other embodiments, the housing 11 may also be an integrated structure, and the semi-transparent and semi-reflective mirror 121 may be fixed to the housing 11 by providing a fixing structure for fixing the semi-transparent and semi-reflective mirror 121 in the housing 11, and this application is not limited thereto. The fixing structure may be a limiting groove, so that the semi-transparent and semi-reflective mirror 121 can be limited in the limiting groove, thereby achieving the purpose of fixing the semi-transparent and semi-reflective mirror 121 in the housing 11. Of course, those skilled in the art may set the specific structural form of the fixing structure according to their needs, and this application is not limited thereto.

[0056] In an optional embodiment, the heat sink 14 can be made of aluminum sheet, graphite sheet or graphite copper sheet. The graphite sheet or graphite copper sheet is a sheet structure made of existing materials such as graphite or graphite copper. Figure 4 and Figure 5 As shown, in a specific example, the heat sink 14 in the shape of an aluminum sheet includes a heat dissipation area and a plurality of rectangular edges 141 located below the heat dissipation area, wherein the rectangular edges 141 can be bent and extended into the groove, and the shape of the heat dissipation area matches the shape of the support frame side 18 of the first bracket 101, for example, a triangle or other shape, so that the heat dissipation area can be fixed on the support frame side 18 by surface bonding, thereby reducing the process difficulty.

[0057] In an optional embodiment, if Figure 6 As shown, a support rib 151 with a curved top surface is formed on the back shell 15 , and the curved surface matches the curved surface of the curved mirror 122 .

[0058] Specifically, in this optional embodiment, when the top surface of the support ribs 151 on the back shell 15 is formed into a curved surface that matches the curved surface shape of the curved mirror 122, the curved mirror 122 can be directly fixed to the back shell 15, thereby supporting and stabilizing the position of the curved mirror 122. In addition, the back shell 15 can be formed in an integrated molding process to reduce the difficulty and cost of the process.

[0059] Optionally, the support ribs 151 of the back shell 15 include multiple square ribs arranged from the inside outward. The closed square ribs serve to improve the support stability of the curved mirror 122. Preferably, a metal plate 153 is disposed within the centermost square rib to further enhance the strength of the back shell 15. Optionally, reinforcing ribs 152 are disposed between the multiple square ribs and the side surfaces of the back shell 15 to further enhance the support strength of the curved mirror 122.

[0060] In an optional embodiment, if Figure 7 As shown, a circuit board 16 is fixed to the back shell 15, and a heat conducting sheet 17 is fixed to the surface of the circuit board 16. A gap is formed between the heat sink 14 and the back shell 15 at a position corresponding to the heat conducting sheet 17, and at least a portion of the heat conducting sheet 17 extends out of the gap. It should be noted that the circuit board 16 can be the control circuit board 16 of the lighting assembly 13 of the strip light strip, and the control circuit board 16 of the lighting assembly 13 in the prior art can be used. The circuit board 16 of the optical reading and writing device will also generate a large amount of heat when used for a long time, causing the temperature of the circuit board 16 to rise. In this application, a heat conducting sheet 17 is provided on the surface of the circuit board 16. The heat conducting sheet 17 extends out of the optical reading and writing device through the gap between the back shell 15 and the heat sink 14, so that the heat conducting sheet 17 can conduct the heat generated by the circuit board 16 to the outside of the optical reading and writing device through the heat conducting sheet 17, thereby achieving the purpose of reducing the temperature of the circuit board 16 and protecting the circuit board 16.

[0061] In an optional embodiment, the portion of the thermal conductive sheet 17 extending from the heat sink 14 is bent and then affixed to the heat sink 14. Specifically, the thermal conductive sheet 17 includes a first portion 171 and a second portion 172. The first portion 171 is fixed to the circuit board 16, and the second portion 172 extends from the optical reader / writer device and affixes to the heat sink 14 to minimize the impact of the thermal conductive sheet 17 on the volume of the optical reader / writer device, thereby reducing the overall volume of the optical reader / writer device.

[0062] In an optional embodiment, the optical reading and writing device further includes a support frame for fixing the auxiliary device body 1. Specifically, the support frame can support the auxiliary device body 1 and fix the position of the auxiliary device body 1 for user convenience.

[0063] In an optional embodiment, the support frame includes a base for fixedly connecting to a fixed surface and a mechanical arm connecting the base and the auxiliary device body 1 .

[0064] Specifically, the base of the optical reading and writing device support frame of the present application can be fixedly connected to a fixed surface, and the fixed surface can be a fixed surface such as the ground or a desktop. Optionally, the base can be any base structure that can stably support the robotic arm and the auxiliary device body 1, and the optical reading and writing device can be stably supported on the fixed surface by the base. Of course, the base can also include a clamping structure, which is clamped to the edge of the desktop to achieve the purpose of fixing the optical reading and writing device. It should be noted that those skilled in the art can set the specific structure of the base according to actual needs. This is a conventional technical means in this field and will not be repeated here.

[0065] In this specific example, the present application connects the base and the auxiliary device body 1 via a robotic arm. The robotic arm, on the one hand, supports the auxiliary device body 1, and on the other hand, adjusts the position of the auxiliary device body 1. The robotic arm may include a multi-segment structure, such as a two-segment or a three-segment structure, and the position of the auxiliary device body 1 is changed and maintained by changing the position of the multi-segment structure. The robotic arm may employ an existing robotic arm product, which is prior art in the field. Those skilled in the art may select a robotic arm and connect the robotic arm to the base and the auxiliary device body 1 according to actual needs, and this application does not limit this.
