It should be understood that those skilled in the art can modify the present invention described herein while still achieving the advantageous effects of the present invention. Therefore, the following description should be understood as being widely known to those skilled in the art, and not as a limitation to the present invention.

[0024] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0025] like Figure 1-2 As shown, an embodiment of the utility model proposes a rear camera structure, including a rear camera lens 1, a decorative part 2, a lampshade 3, a sensor 4 and a mounting plate 5.

[0026] Specifically, the rear camera lens 1 is installed on the decorative piece 2; a through groove is provided on the decorative piece 2; the lampshade 3 is located between the decorative piece 2 and the mounting plate 5, and one end of the lampshade 3 is located in the through groove, and the other end is located on the mounting plate 5; the lampshade 3 and the rear camera lens 1 are respectively located on both sides of the decorative piece 2; a groove 30 is provided on a side of the lampshade 3 close to the mounting plate 5, the sensor 4 is located in the groove 30, and one end of the sensor 4 is installed on the mounting plate 5, and the other end retains a predetermined distance from the inner wall of the lampshade 3.

[0027] The decorative element 2 can support or protect the rear camera lens 1 .

[0028] In this embodiment, by providing a through groove on the decorative member 2 and allowing a portion of the lampshade 3 to be embedded in the decorative member 2, it can help fix the position of the lampshade 3 and also play an aesthetic and protective role.

[0029] In this embodiment, a slot 30 is provided on one side of the lampshade 3 close to the mounting plate 5, and the sensor 4 is located in the slot 30, with one end mounted on the mounting plate 5 and the other end keeping a predetermined distance from the inner wall of the lampshade 3. This can help the sensor 4 receive or transmit signals while avoiding direct exposure to the outside.

[0030] Preferably, the lampshade 3 is a transparent cover, which allows light to pass through and facilitates the sensor 4 to capture signals. The material and size of the lampshade 3 can be set according to actual needs.

[0031] In addition, the cross section of the lampshade 3 is a convex structure, and the overall structure is consistent with the lens of the camera, so that when viewed from the rear camera lens 1, the lampshade 3 and the sensor 4 are the same as the lens as a whole, which is more beautiful.

[0032] As a preferred embodiment, the lampshade 3 is fixed to the decorative member 2 by a first adhesive layer. The adhesive layer can absorb and reduce the impact on the lampshade 3 caused by vibration or impact, thereby protecting the lampshade 3 and internal components from damage. The adhesive layer can provide good sealing performance, prevent dust, moisture and other external impurities from entering between the lampshade 3 and the decorative member 2, and protect the internal optical and electronic components. Using the adhesive layer to fix the lampshade 3 can make the assembly process simpler, and also facilitate future maintenance and replacement, because the adhesive layer can be removed when necessary.

[0033] In one embodiment, the surface of the lampshade 3 close to the rear camera lens 1 is provided with a first curved surface 31, and the surface of the decorative component 2 close to the rear camera lens 1 is provided with a second curved surface 21 connected to the first curved surface 31, and the through groove penetrates the second curved surface 21; the first curved surface 31 and the second curved surface 21 form a curved surface structure.

[0034] The arrangement of the curved surface structure can help control and focus the light emitted from the lampshade 3, thereby improving lighting efficiency. The arrangement of the curved surface structure can also reduce optical distortion, improve image quality, and enhance the optical and aesthetic performance of the device.

[0035] In this embodiment, the lampshade 3 includes a first shell and a second shell; the first shell is located in the through groove, and one end is connected to the second shell; the first arc surface 31 is arranged on the other end of the first shell, the slot 30 is arranged on the side of the second shell away from the first shell, and the sensor 4 is located inside the second shell.

[0036] By installing the sensor 4 inside the second housing, the sensor 4 can be accurately positioned at the desired position, and the inner wall of the slot 30 and the sensor 4 are kept at a predetermined distance, which helps to protect the sensor 4 from external physical damage. In addition, the retention of the predetermined distance can ensure that the transmission efficiency of the signal received or transmitted by the sensor 4 is maximized, while reducing signal interference.

[0037] Preferably, the diameter of the first shell is smaller than the diameter of the second shell, so that the lampshade 3 can be stably installed in the through groove. In addition, the first shell and the second shell are integrally formed, and the diameters of the first shell and the second shell can be set according to actual conditions.

[0038] In this embodiment, the predetermined spacing ranges from 0.15 to 0.3 cm, for example, the predetermined spacing may be 0.15 cm, 0.2 cm, 0.25 cm or 0.3 cm, etc. Those skilled in the art will appreciate that the specific value of the predetermined spacing may be set according to actual needs.

[0039] By maintaining a predetermined distance between the sensor 4 and the inner wall of the lampshade 3, the stability of the signal received by the sensor 4 can be ensured, and signal fluctuations or errors caused by improper spacing can be reduced. The retention of the predetermined distance helps to reduce electromagnetic interference or other external factors that interfere with the sensor 4 signal, and improve the purity and reliability of the signal.

[0040] In one embodiment, the rear camera lens 1 is mounted on the decorative element 2 via a second adhesive layer to improve overall stability and reliability.

[0041] In this embodiment, the sensor 4 is provided with a third adhesive layer for fixing it on the designated position 8 of the communication device. The third adhesive layer can ensure that the sensor 4 is firmly positioned at the designated position 8 of the device to prevent displacement during use, thereby maintaining the stability and reliability of the signal. In addition, the third adhesive layer can absorb and reduce the impact on the sensor 4 caused by vibration or impact, thereby protecting the sensor 4 from damage.

[0042] In this embodiment, a plurality of springs 6 are provided on one side of the mounting plate 5 away from the sensor 4, which are used to be elastically mounted on the main board 7 of the communication device. The springs 6 can provide shock absorption and buffering effects, absorb vibrations caused by device operation or external impact, and protect the sensor 4 and other electronic components from damage. In addition, the provision of the springs 6 enables the mounting plate 5 to be easily mounted on the main board 7 of the communication device, and can also be conveniently disassembled when maintenance or replacement is required. The springs 6 can maintain appropriate contact pressure between the mounting plate 5 and the main board 7, ensure good electrical connection, and reduce failures caused by poor contact.

[0043] In this embodiment, for example, the communication device is a mobile phone, and this embodiment is set in the mobile phone as a rear camera, and the sensor 4 can be a flicker sensor. Light is transmitted from the light-transmitting hole of the rear camera lens 1, and is collected by the arc surface structure of the lampshade 3, and is transmitted to the flicker sensor through the lampshade 3. When the FOV (110°) of the lampshade 3 is greater than the light-transmitting hole (φ4.5) of the rear camera lens 1, the flicker sensor function is also normal. Because the FOV angle can be larger than the diameter of the lampshade 3 and the light-transmitting hole of the rear camera lens 1, the Z-axis position of the flicker sensor is relatively flexible.

[0044] In summary, the rear camera structure proposed in the present invention has the following advantages:

[0045] Through the arrangement of the rear camera lens, decorative piece, lampshade, sensor and mounting plate; and the rear camera lens is installed on the decorative piece; a through groove is provided on the decorative piece; the lampshade is located between the decorative piece and the mounting plate, and one end of the lampshade is located in the through groove, and the other end is located on the mounting plate; the lampshade and the rear camera lens are respectively located on both sides of the decorative piece; a slot is provided on the side of the lampshade close to the mounting plate, the sensor is located in the slot, and one end of the sensor is mounted on the mounting plate, and the other end is kept at a predetermined distance from the inner wall of the lampshade. Compared with the method of adding a diffusion film between the sensor and the rear camera lens in the prior art, the present device uses the structural arrangement of the lampshade to enable the sensor to be flexibly adjusted in the slot according to the requirements of the field of view angle, so that the strobe can be effectively detected. Therefore, the present device can improve the adjustment flexibility of the sensor in the Z direction (optical axis direction), and the structure is beautiful and coordinated.

[0046] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
