[0063] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0064] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or may also have a component that is centrally located. When a component is considered to be "set" on another component, it can be directly set on the other component or may also have a component that is centrally located.

[0065] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0066] An embodiment of this application provides a fixing device for fixing an optical component to a rear shell, including a cover plate connected to the optical component to restrict the movement of the optical component. The cover plate is provided with a first hole and a limiting part. The first hole corresponds to the photosensitive part of the optical component so that the photosensitive part protrudes from the cover plate. The limiting part is used to hold the optical component to restrict the optical component from moving away from the rear shell.

[0067] The aforementioned cover plate confines the optical components to a preset position.

[0068] The embodiments of this application will be further described below with reference to the accompanying drawings.

[0069] Example 1:

[0070] like Figure 1 and Figure 2 As shown, a first embodiment of this application provides a fixing device 111 for fixing an optical component 112. The fixing device 111 includes a cover plate 1111, which is movable and abuts against the optical component 112 and restricts the movement of the optical component 112.

[0071] The cover plate 1111 is provided with a limiting portion 1111b. When the cover plate 1111 is connected with the optical assembly 112, the limiting portion 1111b can limit the movement of the optical assembly 112 in the first direction Z, so that the optical assembly 112 moves in the first direction Z within a limited range, and at this time, the side wall of the cover plate 1111 is located at the periphery of the side wall of the optical assembly 112, which can limit the movement of the optical assembly 112 in the second direction X and the third direction Y perpendicular to the first direction Z, so that the optical assembly 112 cannot move or can only move slightly in the second direction X and / or the third direction Y, so that the optical assembly 112 is located at a preset position.

[0072] As shown in Figure 1 and Figure 3 The fixing device 111 further includes a bracket 1112 connected with the cover plate 1111 to form a containing space 1114 capable of containing the optical assembly 112, which limits the movement of the optical assembly 112 in the second direction X and / or the third direction Y to be unable to move or can only move slightly, and moves in the first direction Z within a limited range.

[0073] The bracket 1112 and the cover plate 1111 can be connected by snap-fitting, or can be fixedly connected by screws or other means. Hereinafter, the bracket 1112 and the cover plate 1111 are connected by snap-fitting as an example for further description.

[0074] The side edge of the cover plate 1111 is provided with a first snap-fitting portion 1111c, and the side edge of the bracket 1112 is provided with a second snap-fitting portion 1112b corresponding to the first snap-fitting portion 1111c. When the cover plate 1111 moves towards the bracket 1112 in the first direction Z, the side edge of the cover plate 1111 first overlaps the projection part of the side edge of the bracket 1112 in the projection plane perpendicular to the second direction X, and the cover plate 1111 continues to move until the first snap-fitting portion 1111c and the second snap-fitting portion 1112b are connected to connect the cover plate 1111 and the bracket 1112 together.

[0075] The first snap-fitting portion 1111c can be a protruding portion protruding from the side edge of the cover plate 1111, and the second snap-fitting portion 1112b can be a snap-fitting hole corresponding to the protruding portion. When the protruding portion and the snap-fitting hole are connected, the snap-fitting hole can limit the movement of the protruding portion in the first direction Z, the second direction X and the third direction Y, so that the cover plate 1111 and the bracket 1112 are connected together. The first snap-fitting portion 1111c can also be a snap-fitting hole, and the corresponding second snap-fitting portion 1112b is a protruding portion corresponding to the snap-fitting hole. The snap-fitting hole and the protruding portion are connected to connect the cover plate 1111 and the bracket 1112 together.

[0076] The fixing device 111 further comprises a first elastic member 1113, one end of the first elastic member 1113 is arranged on the bracket 1112 or the cover plate 1111, and the other end is used for abutting against the optical assembly 112 to elastically arrange the optical assembly 112 in the accommodating space 1114. The following will be further described by taking the first elastic member 1113 fixedly arranged on the bracket 1112 as an example.

[0077] As shown in Figure 1 , Figure 3 and Figure 4 , the first elastic member 1113 is arranged on the side of the bracket 1112 facing the accommodating space 1114, when the optical assembly 112 is placed on the bracket 1112 along the first direction Z, the first elastic member 1113 is located between the optical assembly 112 and the bracket 1112, so that the optical assembly 112 is elastically connected to the bracket 1112. When the cover plate 1111 approaches the optical assembly 112 along the first direction Z until the cover plate 1111 is buckled, the cover plate 1111 limits the optical assembly 112 in the accommodating space 1114 formed by the bracket 1112, and the limiting portion 1111b can block the movement of the optical assembly 112 along the first direction Z.

[0078] The material of the first elastic member 1113 can be EPDM, SIS, SEBS, TPV, TPEE or other materials.

[0079] The cover plate 1111 is further provided with a first hole 1111a, the first hole 1111a penetrates the cover plate 1111 along the first direction Z, so that when the cover plate 1111 limits the optical assembly 112, the photosensitive part 1121 on the optical assembly 112 can protrude from the first hole 1111a to protrude from the cover plate 1111 to better sense the light signal.

[0080] The cross-sectional shape of the cover plate 1111 perpendicular to the first direction Z can be circular or square, as long as it can limit the movement of the optical assembly 112 in the second direction and / or the third direction Y after being buckled and connected with the bracket 1112, the cross-sectional shape of the cover plate 1111 is not specifically limited in the embodiment of the application.

[0081] The shape of the first hole 1111a can be circular, square or other shapes, as long as the photosensitive part 1121 of the optical assembly 112 can protrude and not affect the photosensitive part 1121.

[0082] The fixing device 111 fixes the optical assembly 112 in the following steps:

[0083] The optical assembly 112 is placed on the bracket 1112 along the first direction Z;

[0084] The cover plate 1111 is close to the optical assembly 112 along the first direction Z until the cover plate 1111 is buckled with the bracket 1112, i.e. the optical assembly 112 is limited in the accommodation space 1114.

[0085] The fixing device 111 limits the movement of the optical assembly 112 and improves the position accuracy of the optical assembly 112 by limiting the optical assembly 112 in the accommodation space 1114 through the cover plate 1111 and the bracket 1112.

[0086] Embodiment two:

[0087] As shown in Figure 4 , the second embodiment of the present application provides an optical module 11, which comprises an optical assembly 112 and the fixing device 111 described above. The fixing device 111 is connected with the optical assembly 112 to limit the optical assembly 112 in a preset space, so that the optical assembly 112 cannot move or can only move slightly along the second direction X and / or the third direction Y, and can move within a limited range along the first direction Z.

[0088] When the fixing device 111 fixes the optical assembly 112, the photosensitive part 1121 of the optical assembly 112 protrudes from the upper surface of the cover plate 1111, so that the photosensitive part 1121 protrudes from the cover plate 1111.

[0089] The fixing device 111 can be produced separately and then assembled with the optical assembly 112 to form the optical module 11, or the fixing device 111 and the optical assembly 112 can be integrally formed by injection molding. The present application does not specifically limit the assembly form of the optical module 11.

[0090] The fixing device 111 limits the movement of the optical assembly 112 and improves the position accuracy of the optical assembly 112 by limiting the optical assembly 112 in the preset space through the cover plate 1111 and the bracket 1112.

[0091] Embodiment three:

[0092] As shown in Figure 5 and Figure 6 , the third embodiment of the present application provides an electronic device 1, which comprises a rear shell 12, a first circuit board 14, a display module 13, a battery and the optical module 11 described above. The first circuit board 14 is arranged on the rear shell 12, the optical module 11 is arranged on the rear shell 12 and connected with the first circuit board 14, the battery is arranged on the rear shell 12 and connected with the first circuit board 14, and the display module 13 is connected with the optical module 11 to guide the movement of the display module 13 to connect the rear shell 12.

[0093] The first circuit board 14 is fixedly disposed on the rear cover 12. The first circuit board 14 can be the motherboard of the electronic device 1 or the motherboard of the optical module 11. When the first circuit board 14 is the motherboard of the optical module 11, the electronic device 1 also has a second circuit board (not shown), and the first circuit board 14 is connected to the second circuit board.

[0094] like Figure 7 and Figure 8 As shown, the optical module 11 is positioned at a preset location on the rear shell 12. The optical module 11 can be positioned at the upper left edge, the upper middle edge, the upper right edge, or other locations within the rear shell 12. The following example, with the optical module 11 positioned at the upper left edge within the rear shell 12, will be used for further explanation.

[0095] The bracket 1112 is fixedly installed at a preset position on the rear shell 12, namely the upper left edge inside the rear shell 12. The bracket 1112 can be glued to the rear shell 12, or it can be fixed to the rear shell 12 by screws or other means, as long as the bracket 1112 is stably installed at the preset position on the rear shell 12.

[0096] Since the antenna of the electronic device 1 is located on the upper edge of the housing, close to the optical module 11, the optical module 11 may affect the data transmission of the antenna. In some embodiments, the cover plate 1111 and the bracket 1112 are made of metal, and the bracket 1112 is provided with a spring piece 1112a that is raised along the first direction Z. When the first circuit board 14 is fixed to the rear housing 12, the first circuit board 14 is placed above the spring piece 1112a, so that the spring piece 1112a abuts against the lower surface of the first circuit board 14 by the elastic force of the spring piece 1112a being raised upward along the first direction Z, causing the bracket 1112 to touch the ground. The bracket 1112 and the cover plate 1111 cooperate to form a shielding space to shield the interference signal of the optical component 112, so as to prevent the optical component 112 from affecting the transmission of the antenna.

[0097] like Figure 2 and Figure 7 As shown, the optical component 112 is provided with a connector 1124. When the cover plate 1111 restricts the optical component 112 to a preset position, the connector 1124 can be electrically connected to the first circuit board 14.

[0098] The connector 1124 can extend in a direction perpendicular to the first direction Z and be located above the first circuit board 14, so that the connector 1124 can be connected to the first circuit board 14 without bending, thus extending the service life of the connector 1124.

[0099] When the cover plate 1111 is connected with the bracket 1112 to limit the optical assembly 112 to a preset position in the rear shell 12, the side edges of the cover plate 1111 are located at the periphery of the side edges of the optical assembly 112, limiting the movement of the optical assembly 112 in the second direction X and / or the third direction Y, so that the optical assembly 112 cannot move or can only move slightly in the second direction X and / or the third direction Y. The limiting portion 1111b of the cover plate 1111 is located above the optical assembly 112, limiting the movement of the optical assembly 112 in the first direction Z, so that the optical assembly 112 can only move within the range between the limiting portion 1111b and the bracket 1112 in the first direction Z.

[0100] As shown in Figure 5 and Figure 9 , the display module 13 includes a display screen 131 and a positioning device 132, the display screen 131 and the rear shell 12 are respectively located at two sides of the electronic device 1, and the positioning device 132 is arranged on the side of the display screen 131 facing the inside.

[0101] The display screen 131 is used to display information such as images and texts, and the display screen 131 can be a liquid crystal display screen 131 (LCD), or an organic light-emitting diode display screen 131 (OLED) or other types of display screens 131.

[0102] The positioning device 132 is used to interface with the optical assembly 112 to position the display screen 131, so that the photosensitive portion 1121 of the optical assembly 112 corresponds to a preset position on the display screen 131, and by arranging the optical assembly 112 at the preset position, the display screen 131 can be accurately assembled with the rear shell 12 after being positioned with the optical assembly 112.

[0103] As shown in Figure 7 and Figure 9 , the optical assembly 112 is provided with a first guide portion 1122, and the positioning device 132 is provided with a second guide portion 1321. When the display module 13 moves close to the optical assembly 112 in the first direction Z, the second guide portion 1321 first contacts the first guide portion 1122, and then the first guide portion 1122 guides the second guide portion 1321 to align the optical assembly 112 with the positioning device 132, thereby positioning the display screen 131 at the correct position for assembly, so that the display screen 131 is accurately assembled with the rear shell 12.

[0104] The first guide part 1122 can be a side of the optical assembly 112 body, and the second guide part 1321 can be a wedge-shaped block on the positioning device 132 and facing the inside of the electronic device 1. When the positioning device 132 moves along the first direction Z to approach the optical module 11 with the display screen 131, the plurality of wedge-shaped blocks contact the side of the optical assembly 112 body and guide the positioning device 132, so that the display screen 131 is accurately positioned at the correct position.

[0105] The first guide part 1122 can also be a guide hole formed on the optical assembly 112, and the second guide part 1321 can be a guide column on the positioning device 132 and facing the inside of the electronic device 1. The guide column and the guide hole are connected to guide the positioning device 132, so that the display screen 131 is positioned at the correct position.

[0106] The optical assembly 112 is also provided with a stop part 1123, and the positioning device 132 is also provided with a pressing part 1322. When the display module 13 moves along the first direction Z to approach the optical assembly 112, the pressing part 1322 and the stop part 1123 abut to make the positioning device 132 press the optical assembly 112 to move along the first direction Z, so that the distance between the optical assembly 112 and the display screen 131 is fixed as a preset distance, and the photosensitive accuracy of the optical assembly 112 is ensured. If the stop part 1123 and the pressing part 1322 are not provided, the optical module 11 needs to be accurately positioned in the first direction Z in advance during the assembly of the display module 13, so that the distance between the optical module 11 and the display screen 131 after the assembly of the display screen 131 is within an acceptable range. However, it is difficult to control the distance between the display screen 131 and the optical assembly 112 within a high-precision range due to the production size error of the workpiece and the assembly error of the workpiece, and it inevitably greatly increases the processing cost and the assembly cost.

[0107] The stop part 1123 can be the upper surface of the optical assembly 112 body, and the pressing part 1322 can be a pressing surface on the display assembly and facing the inside of the electronic device 1, as long as the distance between the optical assembly 112 and the display screen 131 is fixed after the pressing part 1322 and the stop part 1123 abut.

[0108] The display module 13 is also provided with a second elastic member 133, and the second elastic member 133 is arranged on the positioning device 132. When the positioning device 132 abuts against the optical assembly 112, the two ends of the second elastic member 133 abut against the positioning device 132 and the optical assembly 112, respectively.

[0109] The second elastic member 133 can be connected to the photosensitive part 1121 on the optical assembly 112, or can be connected to other fragile parts on the optical assembly 112, so that when the positioning device 132 abuts against the optical assembly 112, the second elastic member 133 protects the photosensitive part 1121 and other fragile parts from being damaged by extrusion.

[0110] It should be noted that the optical module 11 of the electronic device 1 is arranged inside the display screen 131, and is a front camera of the electronic device 1. The electronic device 1 also comprises a rear camera arranged on the rear shell 12 and capturing image information of the rear side of the electronic device 1 through the rear shell 12. The rear camera is not specifically described in the embodiments of the present application.

[0111] The assembling steps of the electronic device 1 are as follows:

[0112] The bracket 1112 is placed at a preset position inside the rear shell 12;

[0113] The first circuit board 14 is placed at a preset position inside the rear shell 12;

[0114] The optical assembly 112 is placed on the bracket 1112, and the connecting member is connected to the first circuit board 14;

[0115] The cover plate 1111 is connected and fixed with the bracket 1112;

[0116] The display module 13 is moved close to the rear shell 12 along the first direction Z. After the positioning device 132 is positioned with the optical assembly 112, the rear cover is connected to the rear shell 12.

[0117] In summary, the electronic device 1 limits the optical assembly 112 to a preset position through the fixing device 111, thereby improving the assembling precision of the optical assembly 112. The display screen 131 is aligned and positioned with the optical assembly 112 through the positioning device 132, thereby guiding the display screen 131 to be assembled to the rear shell 12 accurately after being positioned with the optical assembly 112. The bracket 1112 made of metal is connected with the first circuit board 14 to generate a grounding effect. The cover plate 1111 made of metal cooperates with the bracket 1112 to form a shielding space to shield the interference of the optical assembly 112 on the antenna, thereby improving the reliability of the antenna transmission. The electronic device 1 improves the assembling precision and efficiency, and reduces the production and assembling cost of workpieces.

[0118] In addition, those skilled in the art can make other changes within the spirit of the present application. Of course, these changes made according to the spirit of the present application should be included in the scope disclosed by the present application.
