The lens assembly 1 of the camera head 100 according to the embodiment of the present application is described below with reference to fig. 1 and 2.

As shown in fig. 1, a lens assembly 1 of a camera head 100 according to an embodiment of the present application includes: a multi-piece lens 11, a filter 13, and a sealing portion 12.

Specifically, as shown in fig. 1, a plurality of lenses 11 are stacked. The filter 13 is laminated on the lens 11, and at least one pair of adjacent lenses 11 exists among the plurality of lenses 11, and a gap is provided between the pair of lenses 11.

It can be understood that the filter 13 and the plurality of lenses 11 are stacked, the sealing portion 12 surrounds the periphery of the filter 13 and the plurality of lenses 11, and the sealing portion 12 can be formed at the edge of the filter 13 and the edge of the plurality of lenses 11 by injection molding to assemble the filter 13 and the plurality of lenses 11 into a whole, so that the lenses 11 and the filter 13 can be firmly connected to the sealing portion 12, and the lens 11 or the filter 13 is prevented from falling off or displacing under the action of external force. There is a pair of adjacent lenses 11, there is a gap between the lenses 11, and the inner wall surface of the sealing portion 12 in the gap is a rough surface, which can be coated with a first adhesive layer 120, and dust can be adsorbed on the first adhesive layer 120 after falling thereon.

According to the lens assembly 1 of the camera 100 in the embodiment of the application, the encapsulation part 12, the plurality of lenses 11 and the filter 13 are integrally molded and encapsulated, the encapsulation part 12 surrounds the periphery of the lenses 11, and at least part of the edge of the lenses 11 is embedded in the encapsulation part 12, so that the structure that the lenses 11 are fixed on the lens assembly 1 by using a bracket in the related art is eliminated, the volumes of the lenses 11 and the encapsulation part 12 are reduced, and the lens assembly 1 is miniaturized. Through setting up reference surface 119 to the rough surface, the light irradiation is back on the rough surface, and the reflection of light path is slow reflection, and the light after the reflection can be transmitted to around to can avoid reflecting and concentrate formation glare, influence the formation of image of lens subassembly. The first adhesive layer 120 coated on the reference surface 119 can be used to adsorb dust particles in the gap of the lens 11, so that the light transmission effect of the lens assembly 1 can be improved, and the imaging effect of the camera 1 can be improved.

According to some embodiments of the present application, first adhesive layer 120 is an oily anti-dust glue. The oily dustproof glue has fluidity and adhesiveness, and can be directly brushed on the reference surface 119. Therefore, the first adhesive layer 120 can be conveniently coated on the reference surface 119, the oily dustproof glue has good adhesion performance, and the oily dustproof glue has good dust collection effect.

As shown in fig. 1, according to some embodiments of the present application, the peripheral wall of the lens 11 is flush with the peripheral wall of the enclosure 12, and the peripheral wall of the filter 13 is flush with the peripheral wall of the enclosure 12. Therefore, the packaging part 12 is more attached to the lens 11 and the filter sheet 13, the size of the packaging part 12 is reduced while the packaging strength is ensured, the size and the size of the lens assembly 1 are further reduced, and the lens assembly 1 is miniaturized.

According to some embodiments of the present application, reference surface 119 may be roughened by a grit blasting process. The sand blasting process is a process of cleaning and roughening the surface of a matrix by using the impact action of high-speed sand flow. Compressed air is used as power to form a high-speed spray beam to spray materials (copper ore sand, quartz sand, carborundum, iron sand and Hainan sand) to the surface of a workpiece to be treated at a high speed, so that the appearance or the shape of the outer surface of the workpiece is changed, and the surface of the workpiece obtains certain cleanliness and different roughness due to the impact and cutting action of an abrasive on the surface of the workpiece, so that the mechanical property of the surface of the workpiece is improved, the fatigue resistance of the workpiece is improved, the adhesive force between the workpiece and a coating is increased, the durability of a coating film is prolonged, and the leveling and decoration of a coating are facilitated. It will thus be appreciated that reference surface 119 may be roughened by the impingement of high velocity sand streams to form a roughened surface having a rough texture. Therefore, different roughness can be formed at different positions on the reference surface 119 through a sand blasting process, the sand blasting process is a mature process technology, and the process flow is simple and easy to implement. .

According to some embodiments of the present application, reference surface 119 may be formed with a rough surface by an electric discharge process. Electric discharge machining utilizes the action of electric erosion generated by pulse discharge between two electrodes immersed in a working fluid to erode the surface. In the case of electric discharge machining, the tool electrode and the reference surface 119 are respectively connected to both poles of a pulse power supply and immersed in a working fluid, or the working fluid is filled in a discharge gap. The tool electrodes are controlled to approach the reference surface 119 by the automatic gap control system, and when the gap between the two electrodes reaches a certain distance, the pulse voltage applied to the two electrodes breaks down the working fluid to generate spark discharge. A large amount of heat energy is instantaneously concentrated in a discharge micro-channel, the temperature can reach more than ten thousand ℃, and the pressure also changes rapidly, so that the local surface is melted and gasified immediately, and splashed into the working liquid in an explosive manner, and is condensed rapidly to form solid metal particles which are taken away by the working liquid. At this time, a minute pit trace is left on the reference surface 119, the discharge is temporarily stopped, and the working fluid between the two electrodes is restored to an insulating state. Then, the next pulse voltage is broken down at another point where the electrodes are relatively close to each other to generate spark discharge, and the above process is repeated to form an uneven rough surface on the reference surface 119. When the reference surface 119 is treated by the electric spark process, burrs and tool mark grooves are not generated, electric energy can be directly used for processing, and automation is convenient to realize.

According to some embodiments of the present application, as shown in fig. 1, in the optical path transmission direction, the lens 11 located at the most upstream (upper side as shown in fig. 1) of the optical path is the first lens 111, the lens 11 located at the most downstream (lower side as shown in fig. 1) of the optical path is the second lens 112, the surface of the side (upper side as shown in fig. 1) of the first lens 111 far from the second lens 112 is the first surface 115, the end surface of the end (upper end as shown in fig. 1) of the packaging part 12 facing the optical path upstream is the first end surface 117, the first end surface 117 is flush with the contour line of the first surface 115, and the filter 13 is located between the second lens 112 and the first lens 111. Therefore, when the packaging part 12 and the lens 11 are integrally molded, the first end surface 117 of the packaging part 12 is more attached to the first lens 111, and the packaging part 12 is not easy to damage the first lens 111, so that the difficulty of the injection molding packaging process is reduced, and the excellent rate of injection molding packaging is improved.

Further, as shown in fig. 1, the first mirror 111 may be a convex lens. The convex lens has a focusing function, when a user shoots, a scene generates an inverted and reduced optical image through the convex lens, and then the scene with a wider visual angle can be focused in the camera 100 through the convex lens. In addition, the convex lens can isolate dust or small particles at the outer side of the lens assembly 1, and the convex lens is convenient to scrub, so that the dust or the small particles can be conveniently removed from the lens assembly 1.

According to some embodiments of the present application, as shown in fig. 1, in the optical path transmission direction, the lens 11 located at the most upstream (upper side as shown in fig. 1) of the optical path is the first lens 111, the lens 11 located at the most downstream (lower side as shown in fig. 1) of the optical path is the second lens 112, the surface of the side (lower side as shown in fig. 1) of the second lens 112 away from the first lens 111 is the second surface 116, the end surface of the packaging part 12 facing the end (lower end as shown in fig. 1) of the optical path downstream is the second end surface 118, the second end surface 118 is flush with the contour line of the second surface 116, and the filter 13 is located between the second lens 112 and the first lens 111. Therefore, when the packaging part 12 and the lens 11 are integrally molded, the second end face 118 of the packaging part 12 is more attached to the second lens 112, and the packaging part 12 is not easy to damage the second lens 112, so that the difficulty of the injection molding packaging process is reduced, and the yield of the injection molding packaging is improved.

According to some embodiments of the present application, as shown in fig. 1, the second optic 112 may be a concave lens. The concave lens has the function of diverging light, and the light projected on the concave lens through the first lens 111 can be incident on the image sensor through the imaging after divergence, so that the image sensor can analyze and process the image, and further clear imaging can be obtained.

According to some embodiments of the present application, filter 13 may be blue glass. The blue glass is made of blue glass material (common optical filters are common optical glass), and the blue glass has the effect of filtering infrared light in an absorption mode. Because of the higher transmittance of blue light, the glass filter has better transmittance than red-orange glass filter, can filter infrared light above 630nm (but allows the rest light with wide wave band from ultraviolet to infrared light to pass through), and can filter thoroughly.

The principle and law of refraction of light can be used to derive: the longer the wavelength, the smaller the refractive index; the shorter the wavelength, the larger the refractive index. Therefore, when the light rays enter the camera of the mobile phone and are refracted by the lens, the visible light and the infrared light can form images on different target surfaces. Where the visible light is imaged as a color image and the infrared light is imaged as a black and white image. When we adjust the image formed by visible light, namely image focusing and back focus adjustment, infrared light forms a virtual image on the target surface, thereby affecting the color and quality of the image. The blue glass can filter out infrared light, avoids a target surface virtual image caused by the infrared light, and can restore the real color of an object, thereby solving the problem of image color distortion.

According to some embodiments of the present application, as shown in fig. 1, the lens 11 may include a light passing portion 113 and a connecting portion 114, the connecting portion 114 extending along a circumferential direction of the light passing portion 113, the connecting portion 114 being embedded in the package portion 12. When a user takes a picture, the light can be transmitted to the image processor through the light-passing portion 113, and the connecting portion 114 is used for connecting and fixing the light-passing portion 113. On the premise of ensuring that the light passage of the light passing part 113 is not obstructed, the connecting part 114 is embedded in the packaging part 12, so that the volumes of the connecting part 114 of the lens 11 and the packaging part 12 are reduced, and the lens assembly 1 is miniaturized.

Further, as shown in fig. 1, the connecting portion 114 has a ring shape. The annular connecting portion 114 facilitates the packaging of the packaging portion 12 to the connecting portion 114, improves the packaging effect of the packaging portion 12 to the connecting portion 114, and further enhances the limiting and fixing of the packaging portion 12 to the lens 11. In addition, the annular connecting portion 114 can increase the contact area between the packaging portion 12 and the connecting portion 114, reduce the contact stress between the packaging portion 12 and the connecting portion 114, and thus reduce the occurrence of cracks in the connecting portion 114 during the integral packaging process or under the action of external force.

In some embodiments of the present application, the connection portion 114 is plural, and the plural connection portions 114 are distributed at intervals along the circumferential direction of the light passing portion 113. Therefore, the connection stability between the connecting portion 114 and the package portion 12 is ensured, and the complexity of the manufacturing process of the connecting portion 114 is reduced, so that the manufacturing cost of the lens 11 is reduced, and the yield of the manufacturing of the connecting portion 114 is improved.

Through setting up reference surface 119 to the rough surface, the light irradiation is back on the rough surface, and the reflection of light path is slow reflection, and the light after the reflection can be transmitted to around to can avoid reflecting and concentrate formation glare, influence the formation of image of lens subassembly.

The touch panel, also called a touch screen, may collect touch operations of a user (for example, operations of the user on or near the touch panel using any suitable object or accessory such as a finger, a stylus, etc.) and drive the corresponding connection device according to a preset program.

Alternatively, the touch panel may include two parts of a touch detection device and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch detection device, converts the touch information into touch point coordinates, sends the touch point coordinates to the processor, and can receive and execute commands sent by the processor. In addition, the touch panel may be implemented in various types such as a resistive type, a capacitive type, an infrared ray, and a surface acoustic wave. The input unit may include other input devices in addition to the touch panel. In particular, other input devices may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, switch keys, etc.), a trackball, a mouse, a joystick, and the like.

WiFi belongs to short-distance wireless transmission technology, and the electronic equipment 1000 can help a user to receive and send e-mails, browse webpages, access streaming media and the like through a WiFi module, and provides wireless broadband internet access for the user. It is understood that the WiFi module is not an essential component of the electronic device 1000 and may be omitted entirely as needed within the scope of not changing the nature of the application.

In addition, the handset may also include at least one sensor, such as an attitude sensor, a light sensor, and other sensors.

Specifically, the attitude sensor may also be referred to as a motion sensor, and as one of the motion sensors, a gravity sensor may be cited, which uses an elastic sensing element to make a cantilever-type displacer and uses an energy storage spring made of the elastic sensing element to drive an electrical contact, thereby realizing conversion of a change in gravity into a change in an electrical signal.

Another example of the motion sensor is an accelerometer sensor, which can detect the magnitude of acceleration in each direction (generally, three axes), detect the magnitude and direction of gravity when stationary, and can be used for applications for recognizing the posture of a mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer and tapping), and the like.

In the embodiment of the present application, the motion sensors listed above may be used as elements for obtaining "attitude parameters" described later, but the present application is not limited thereto, and other sensors capable of obtaining "attitude parameters" fall within the protection scope of the present application, such as a gyroscope and the like, and the operation principle and data processing procedure of the gyroscope may be similar to those of the prior art, and the detailed description thereof is omitted here for avoiding redundancy.

In addition, in this embodiment of the application, as the sensor, other sensors such as a barometer, a hygrometer, a thermometer, and an infrared sensor may also be configured, which are not described herein again.

The light sensor may include an ambient light sensor that adjusts the brightness of the display panel according to the brightness of ambient light, and a proximity sensor that turns off the display panel and/or the backlight when the mobile phone is moved to the ear.

The display unit may be used to display information input by the user or information provided to the user and various menus of the mobile phone. The display unit may include a display panel, and optionally, the display panel may be configured in the form of a Liquid Crystal Display (LCD), an Organic Light-Emitting Diode (OLED), or the like. Further, the touch panel may cover the display panel, and when the touch panel detects a touch operation thereon or nearby, the touch panel transmits the touch operation to the processor to determine the type of the touch event, and then the processor provides a corresponding visual output on the display panel according to the type of the touch event.

The audio circuitry, speaker, and microphone may provide an audio interface between a user and the electronic device 1000. The audio circuit can transmit the electric signal converted from the received audio data to the loudspeaker, and the electric signal is converted into a sound signal by the loudspeaker to be output; on the other hand, the microphone converts the collected sound signal into an electrical signal, which is received by the audio circuit and converted into audio data, which is then output to the processor for processing, and then transmitted to another electronic device 1000 via the rf circuit, or output to the memory for further processing.

The processor is a control center of the electronic device 1000, is installed on the circuit board assembly, connects various parts of the whole electronic device 1000 by using various interfaces and lines, and performs various functions of the electronic device 1000 and processes data by operating or executing software programs and/or modules stored in the memory and calling data stored in the memory, thereby performing overall monitoring of the electronic device 1000. Alternatively, the processor may include one or more processing units; preferably, the processor may integrate an application processor, which mainly handles operating systems, user interfaces, application programs, etc., and a modem processor, which mainly handles wireless communications.

The power supply can be logically connected with the processor through the power management system, so that the functions of managing charging, discharging, power consumption management and the like are realized through the power management system. Although not shown, the electronic device 1000 may further include a bluetooth module, a sensor (e.g., an attitude sensor, a light sensor, other sensors such as a barometer, a hygrometer, a thermometer, an infrared sensor, etc.), etc., which are not described herein.

It should be noted that the mobile phone is only an example of the electronic device 1000, and the application is not particularly limited, and the application may be applied to the electronic device 1000 such as a mobile phone and a tablet computer, and the application is not limited thereto.
