In addition, the lens and lens mount are not easy to match, and the matching degree is poor. If they are too loose, they are easy to loosen before gluing and cause defocus, or if they are too tight, the lens cannot be installed in the lens mount, affecting the assembly yield.

[0027] In addition, the technical solutions between the various embodiments of the present invention may be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in the field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the embodiments of the present invention.

[0028] like Figure 1 , Figure 2 As shown, an efficient heat dissipation camera module proposed in an embodiment of the present invention includes a lens holder 100 and a lens 200 installed in the lens holder 100. The lens 200 is gap-connected with the lens holder 100, and glue is contained in the gap between the lens holder 100 and the lens 200.

[0029] In the technical solution adopted in this embodiment, by setting the lens 200 and the lens holder 100 as a gap connection, the lens 200 can be conveniently installed in the lens holder 100 during the later assembly, so as to avoid the lens 200 being unable to be screwed into the lens holder 100 due to the lens 200 and the lens holder 100 being too tightly matched. At the same time, glue is applied on the barrel of the lens 200. After the lens 200 is screwed into the lens holder 100, the applied glue can be filled into the gap between the lens 200 and the lens holder 100. Before the glue solidifies, the lens 200 can be rotated under the action of external force, which is convenient for the staff to focus. After the glue solidifies, the reliability of the connection between the lens 200 and the lens holder 100 is guaranteed, and the defocusing phenomenon caused by the lens 200 and the lens holder 100 being too loose is avoided, thereby improving the assembly yield. In addition, in the technical solution of the present invention, the various features work together to integrate the high-efficiency heat dissipation camera module, simplify the assembly process of the back-end finished product line, ensure the accurate matching of the lens 200 and the lens holder 100, and improve the assembly yield.

[0030] Specifically, the high-efficiency heat dissipation camera module includes a lens 200 and a lens holder 100. The lens 200 includes a barrel and a lens. The outer surface of the barrel is provided with an external thread, and the lens holder 100 is provided with an internal thread corresponding to the external thread. It can be understood that the lens 200 and the lens holder 100 are threadedly connected. Generally, the lens 200 and the lens holder 100 can be produced by different manufacturers. During the assembly process of the lens 200 and the lens holder 100, it is easy to fail to assemble or assemble too loosely, which affects the assembly yield. In this embodiment, in order to ensure that the lens 200 can be installed in the lens mount 100, the lens 200 and the lens mount 100 are set to be gap-connected. It can be understood that the external thread of the lens 200 and the internal thread of the lens mount 100 are loosely matched, which ensures that the lens 200 can be installed in the lens mount 100. At the same time, in order to prevent defocusing caused by the loose assembly of the lens 200 and the lens mount 100, glue is filled in the assembly gap between the lens 200 and the lens mount 100. Since the glue takes a certain amount of time to solidify, the lens 200 can be allowed to rotate before the glue solidifies to facilitate focusing. At the same time, after the glue solidifies, the close connection between the lens 200 and the lens mount 100 can be ensured to prevent the formation of shadows. That is to say, through the gap connection between the lens 200 and the lens 100 and the glue filled in the gap between the two, the lens 200 can be well matched with the lens mount 100 during assembly, thereby improving the assembly yield and efficiency.

[0031] In this embodiment, the glue can be a thermally conductive gel and / or a UV shadowless glue. The thermally conductive gel has a good thermal conductivity and can perform good heat dissipation and cooling for the high-efficiency heat dissipation camera module. At the same time, the viscosity of the thermally conductive gel is relatively low, and it generally takes 24 hours to solidify, which allows the lens 200 to rotate under the torque of 2 to 6 Newtons, thereby facilitating focusing. Shadowless glue is also called ultraviolet glue. It can only be cured under the premise that ultraviolet rays are irradiated to the glue liquid, that is, the photosensitizer in the shadowless glue will bond with the monomer when exposed to ultraviolet rays. The viscosity of the shadowless glue is relatively strong, and the curing speed is also fast, and it can generally be completely cured in 10 to 60 seconds. In the process of actual application, it can be selected according to needs. In this embodiment, a combination of thermally conductive gel and UV shadowless glue can be used. It can be understood that before focusing, the barrel of the lens 200 is coated with thermally conductive gel. After focusing, the lens 200 and the lens holder 100 are fixed by applying UV shadowless glue. Of course, in other embodiments, thermal conductive gel may be used alone, or UV glue may be used alone. It should be noted that if UV glue is used alone, the focusing work needs to be completed quickly before solidification. The time required for solidification can also be extended by reducing the intensity of ultraviolet radiation.

[0032] Furthermore, the high-efficiency heat dissipation camera module also includes a heat conductor 900 , which is disposed on the lens holder 100 , and glue is placed in the gap between the lens 200 and the heat conductor 900 , and the glue is used for heat conduction and filling the gap.

[0033] In the technical solution adopted in this embodiment, in order to better dissipate heat, a heat conductor 900 is provided on the lens mount 100, and glue is used to fill the gap between the lens 200 and the heat conductor 900. Specifically, the lens 200 is mounted on the lens mount 100, and glue (at least one of shadowless glue and heat dissipation glue) is applied between the lens 200 and the lens mount 100. After focusing and fixing, the heat conductor 900 is mounted on the lens mount 100, and glue is applied to the gap between the lens 200 and the heat conductor 900. Preferably, the glue is a heat conductive glue, which can not only fill the gap between the lens 200 and the heat conductor 900, but also improve the heat dissipation effect.

[0034] Further, see Figure 1 , Figure 2 In one embodiment of the present invention, a heat conductive member 900 is disposed on a side of the lens holder 100 facing the lens 200 , at least two heat conductive members 900 are disposed, the two heat conductive members 900 are arranged at intervals, the heat conductive member 900 is disposed around the lens 200 , and glue is placed in the gap between the heat conductive member 900 and the lens 200 .

[0035] In the technical solution adopted in this embodiment, in order to better dissipate heat, a heat conductive member 900 is provided on the lens holder 100. The heat conductive member 900 is made of a heat-conducting metal material. The shape of the heat conductive member 900 is semicircular. Two semicircular heat conductive members 900 are arranged around the lens 200. The interval between the two heat conductive members 900 can make air flow smoothly, which is more conducive to heat dissipation. The gap between the heat conductive member 900 and the lens 200 is filled with glue, which is preferably a heat conductive glue.

[0036] Further, see Figure 1 , Figure 2 In one embodiment of the present invention, the lens mount 100 includes a first mount body 110 and a second mount body 120 that are detachably connected, the lens 200 is installed on the first mount body 110, an installation space is set between the first mount body 110 and the second mount body 120, and a surface of the second mount body 120 on one side facing the first mount body 110 is recessed to form the installation space.

[0037] In the technical solution adopted in this embodiment, in order to ensure the quality of the image captured by the high-efficiency heat dissipation camera module, the high-efficiency heat dissipation camera module generally also includes a control element. Different filters can be selected in different environments such as night or day. For the consideration of shading and cleanliness, the control element generally works in a fully enclosed environment. In this embodiment, the lens holder 100 is configured as a first seat body 110 and a second seat body 120, and an installation space is provided between the first seat body 110 and the second seat body 120. This can facilitate the installation of the control element. In addition, the detachable connection simplifies the structure and facilitates maintenance.

[0038] In this embodiment, the surface of one side of the second base body 120 facing the first base body 110 is recessed to form an installation space. It can be understood that the above-mentioned groove is opened on the second base body 120, and the groove can be divided into two connected parts, one part is used to install the sensor 300, the connecting plate, and the flexible circuit board 400, and the other part is used to install the filter switch 500. The depth of the groove can be equal to the sum of the superimposed thickness of the sensor 300, the connecting plate, the flexible circuit board 400, and the filter switch 500. In this way, the overall thickness of the high-efficiency heat dissipation camera module can be reduced, making the high-efficiency heat dissipation camera module more compact and practical.

[0039] In this embodiment, the heat conducting member 900 is disposed on the first base body 110 .

[0040] Further, see Figure 1 In one embodiment of the present invention, the high-efficiency heat dissipation camera module further includes a sensor 300, a connecting plate 800 and a flexible circuit board 400 connected in sequence. The sensor 300, the connecting plate 800 and the flexible circuit board 400 are installed in the installation space, and the flexible circuit board 400 is bonded to the second base body 120.

[0041] In the technical solution adopted in this embodiment, the sensor 300 is used to detect and output a control signal so that the efficient heat dissipation camera module can capture a clear image. The sensor 300 is mounted on one side of the connecting plate 800. At the same time, the flexible circuit board 400 is mounted on the other side of the connecting plate 800. The flexible circuit board 400 is connected to the sensor 300 through the connecting plate 800 and transmits signals. The connecting plate 800 can adopt a PCB printed circuit board blank board. First, it is convenient to fix the sensor 300 and the flexible circuit board 400, and second, it can realize the electrical connection between the sensor 300 and the flexible circuit board 400. It can be understood that the sensor 300 and the flexible circuit board 400 are integrated into a module through the connecting plate 400, which simplifies the assembly process and is convenient for use. In addition, the signal transmission lines are integrated between the sensor 300 and the flexible circuit board 400, and the flexible circuit board 400 has a high wiring density, which can meet the needs of signal line integration. The flexible circuit board 400 is bonded and fixed to the second base body 120 by glue. The glue can be heat dissipation glue, which is convenient for dissipating the heat generated by the flexible circuit board 400. A groove can be provided on the surface of the second base body 120 facing the first base body 110, and the sensor 300, the connecting plate, and the flexible circuit board 400 are arranged in the groove. Such a setting can reduce the overall thickness of the high-efficiency heat dissipation camera module, making the volume of the high-efficiency heat dissipation camera module smaller, and expanding the application range of the low-efficiency heat dissipation camera module. At the same time, in order to facilitate positioning, a positioning column can be provided at the bottom of the groove, and correspondingly, a positioning groove can be provided on the connecting plate, and the positioning column extends into the positioning groove to facilitate positioning during assembly.

[0042] Further, see Figure 1 , Figure 3 , Figure 4 In one embodiment of the present invention, the high-efficiency heat dissipation camera module also includes a filter switch 500 arranged in the installation space, the filter switch 500 is arranged on the side of the sensor 300 facing the first base body 110, the filter switch 500 is provided with two conductive sheets 600, and the surface of the flexible circuit board 400 is provided with contact sheets 700 corresponding to the two conductive sheets 600.

[0043] In the technical solution adopted in this embodiment, the filter switch 500 is used to switch different filters to adapt to different use environments of different high-efficiency heat dissipation camera modules. The filter switch 500 generally includes a magnetic drive component and a filter support frame. The magnetic drive component can generate a magnetic field under the action of different currents, thereby driving the filter support frame to move to switch the corresponding filter. In this embodiment, two conductive sheets 600 are set in the filter switch 500 to transmit current, wherein one end of the two conductive sheets 600 extends to the inside of the filter switch 500, and the other end is connected to the contact sheet 700 set on the flexible circuit board 400. The material of the conductive sheet 600 and the contact sheet 700 can be copper. Such a setting replaces the traditional wire connection, avoids the wire breaking and affecting normal use, improves the reliability of the connection, and at the same time, saves the use of wires and prevents the wires from being arranged in a disordered manner and affecting the appearance. In order to further ensure the reliability of the connection, a convex head is set at the connecting end of the conductive sheet 600 and the flexible circuit board 400. At the same time, the contact sheet 700 is recessed on the flexible circuit board 400, and the convex head is inserted into the above-mentioned recess of the flexible circuit board 400. Such a setting can ensure that the conductive sheet 600 can be accurately connected to the contact sheet 700.

[0044] Furthermore, in an embodiment of the present invention, the first base body 110 and the second base body 120 are fixed by heat riveting.

[0045] In the technical solution adopted in this embodiment, the first base body 110 and the second base body 120 are fixed by hot riveting and pressing, and the process is mature and easy to operate.

[0046] Furthermore, in an embodiment of the present invention, a heat dissipation adhesive is coated at a connection point between the first base body 110 and the second base body 120 .

[0047] In the technical solution adopted in this embodiment, heat dissipation glue is applied at the connection between the first base body 110 and the second base body 120 to reduce the thermal resistance that may occur at the joint surface and improve the heat conduction efficiency.

[0048] Furthermore, in one embodiment of the present invention, the lens holder 100 is made of thermally conductive plastic, and the thermal conductivity of the thermally conductive plastic is 0.5 to 30 W / m·°C.

[0049] In the technical solution adopted in this embodiment, after the sensor 300 and the flexible circuit board 400 are moduled, the temperature rise problem of the sensor 300 will be aggravated because there is no traditional circuit board for heat dissipation and cooling. In order to alleviate the temperature rise problem, a thermally conductive plastic with a thermal conductivity of 0.5 to 30 W / m·degree is used as the material of the lens holder 100. At the same time, it can also be used as the material of the barrel of the lens 200. Such a setting can effectively dissipate the heat generated by the sensor 300, avoid fogging of the lens 200 due to uneven temperature rise or large temperature difference, prevent imaging defocus, and increase the service life of the camera module.

[0050] Furthermore, in an embodiment of the present invention, the outer surface of the lens holder 100 is a heat dissipation fin or a columnar structure.

[0051] In the technical solution adopted in this embodiment, the outer surface of the lens holder 100 is provided with heat dissipation fins or a columnar structure, which can increase the heat dissipation area, improve the heat conduction efficiency, and be more conducive to heat dissipation.

[0052] An embodiment of the present invention further proposes a camera device, which includes the above-mentioned high-efficiency heat dissipation camera module. Specifically, the specific structure of the high-efficiency heat dissipation camera module refers to the above-mentioned embodiment. Since the camera device adopts all the technical solutions of the above-mentioned embodiment, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiment, which will not be repeated here one by one.

[0053] In the technical solution provided in this embodiment, the assembly method of the high-efficiency heat dissipation camera module is:

[0054] 1. Preparation steps: provide a connecting plate 800, mount the sensor 300 on one side of the connecting plate 800, mount the flexible circuit board 400 on the other side of the connecting plate 800, and electrically connect the sensor 300 to the flexible circuit board 400; provide a filter switch 500, and set the conductive sheet 600 on the side of the filter switch 500 facing the flexible circuit board 400.

[0055] 2. Fixing step: stack the filter switch 500, the sensor 300, the connecting plate 800, and the flexible circuit board 400 in sequence, and glue them to the second base body 120 by glue; fix the first base body 110 and the second base body 110 by hot riveting and pressing.

[0056] 3.

At the same time, the viscosity of the thermal conductive gel is low and it usually takes 24 hours to solidify, allowing the lens 200 to rotate under a torque of 2 to 6 Newtons, thereby facilitating focusing. After focusing, the lens 200 and the lens mount 100 are fixed by applying UV shadowless glue. The shadowless glue has a strong viscosity and cures quickly.

[0066] 9. The convex head of the conductive sheet 600 and the concave head of the contact sheet 700 can ensure that the conductive sheet 600 can be accurately connected to the contact sheet 700, further improving the stability and reliability of the connection.
