Description

Camera modules, cameras and camera products

This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on May 27, 2022, with application number 202221316851.3 and the application name "Camera Module, Camera and Camera Products", the entire content of which is incorporated by reference in in this application.

Technical field

This application relates to the field of optical imaging technology, and in particular to a camera module, a camera and a camera product.

Background technique

In intelligent transportation systems, surveillance cameras mainly include electric police and bayonet models.

Among them, the bayonet type surveillance camera is mainly used to monitor conditions such as roads. When shooting oncoming cars, because the lens module and the window glass are set apart, the light source beam emitted by the car's lights will appear "ghost" during imaging. "Shadow" phenomenon affects the imaging of surveillance cameras and reduces the clarity of imaging.

In addition, electric police type surveillance cameras are mainly used to detect conditions such as intersections, and the incident strong light source of the camera is mainly sunlight. If the camera lens and the window glass are at a certain angle, when sunlight enters the camera, the sunlight beam will appear as a "ghost" phenomenon during imaging.

For surveillance camera products, in a certain working environment, if the "ghosting" phenomenon does not appear when facing the strong light source of the environment, or if the "ghosting" phenomenon is weakened or eliminated through a certain design, it will appear after changing the working environment. The "ghosting" phenomenon requires the camera to be replaced in another working environment, and the camera is not versatile enough.

Utility model content

When the camera module described in this application is used in different working environments and faces strong light source incident angles from different directions, the central axis can be adjusted by switching the assembly form after the first bracket and the second bracket are connected and formed. The relative angle between the lens and the optical axis ensures that the secondary reflected beam formed by the strong light source reflecting through the lens and the window can deviate from the lens and not be imaged on the imaging sensor, thereby reducing or eliminating the "ghost" phenomenon. The camera module described in this application can reduce or eliminate the "ghosting" phenomenon under different incident directions of strong light sources, improving the versatility of camera products produced on the same platform.

Detailed ways

The embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

To facilitate understanding, the English abbreviations and related technical terms involved in the embodiments of the present application are first explained and described below.

Protective cover, also called protective cover. In the field of surveillance cameras, the protective cover is a protective shell set outside the surveillance camera. It is mainly divided into indoor protective cover and outdoor protective cover. Electrical components such as the lens module, motherboard, and processing module are all installed in the protective cover. The above-mentioned electrical components are protected mainly in terms of dustproof, waterproof, windproof and external impact protection. For some monitoring equipment, the shield also needs to ensure a certain degree of sealing and heat preservation, and be able to adjust the temperature inside the shield to ensure that the electrical components in the shield work in a suitable environment.

The viewing window is fixedly installed on the light incident side of the shield. Since the shield must ensure a certain degree of sealing, the viewing window needs to be sealed and fixedly connected to the shield. The shield is generally made of plastic or metal and is opaque. In order to ensure that the lens module obtains images of the target area, the window is made of light-transmissive material, mostly made of glass. In addition, in order to prevent the light path from being deflected and other changes after the light beam passes through the glass lens, the window is mostly flat-shaped.

Lens module refers to a component that obtains external light sources and can obtain images of the light-incident side area. It is composed of multi-layer lenses, optical filters, image sensors, mounts, circuit boards and other components. It is generally an integral module and is installed on the protective cover. Inside the cover, the light transmitted through the window enters the lens module, and the lens module creates images based on the obtained light information. The lens module has an optical axis, which is a ray of light that passes vertically through the center of the lens.

It should be clear that the described embodiments are only some of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of this application.

The terminology used in the embodiments of the present application is only for the purpose of describing specific embodiments and is not intended to limit the present application. As used in the embodiments and the appended claims, the singular forms "a," "the" and "the" are intended to include the plural forms as well, unless the context clearly dictates otherwise.

It should be understood that the term "and/or" used in this article is just a way to describe the same field of associated objects, indicating that there can be three relationships, for example, A and/or B, which can mean: A alone exists, and A exists at the same time and B, there are three cases of B alone. In addition, the character "/" in this article generally indicates that the related objects are an "or" relationship.

Depending on the context, the word "if" as used herein may be interpreted as "when" or "when" or "in response to determining" or "in response to Detection". Similarly, depending on the context, the phrase "if determined" or "if (stated condition or event) is detected" may be interpreted as "when determined" or "in response to determining" or "when (stated condition or event) is detected )" or "in response to detecting (a stated condition or event)".

Bayonet, that is, "standard bayonet". Bayonet systems (including bayonet type cameras) are generally set up at city entrances and exits to count traffic flow and identify and identify blacklisted vehicles, suspicious vehicles, etc. Intercept, carry out key security monitoring of the above-mentioned locations, mainly photograph the driver's status in passing vehicles, and need to see the driver's face and the situation in the car clearly, so the bayonet system has higher requirements for picture pixels and needs to be seen clearly The driver’s face and the situation inside the car. The bayonet camera has small application scenarios and rich vehicle details. It is generally used with a strobe light to capture the front of the car, so that the faces in the car can be seen clearly. Referring to Figure 1, when the camera 900 is used in the working environment of a bayonet camera, it is mostly used on the road to take pictures of oncoming vehicles. The strong light source 700 is mainly a car headlight, especially at night. When the light intensity is high, a "ghost" phenomenon may occur when the camera 900 is imaging.

Electric police, also known as "electronic police", mainly use electronic equipment to investigate and deal with traffic violations. The electronic police detection scope includes: running a red light to capture, crossing the line, changing lanes, illegal U-turns and speeding, etc. A series of traffic violations. Electronic police (including electric police cameras) systems are generally located on some of the more complex roads in cities (multiple lanes, intersections, etc.). The electronic police system captures illegal vehicles through front-end cameras and captures pictures of the vehicle violation process. The pictures clearly show the status of the signal light, the position of the parking line, the illegal lane, the illegal vehicle's license plate number, license plate color, body color, vehicle type, violation time, Information such as location, vehicle speed and driving direction is then transmitted to the server platform of the monitoring center, and illegal vehicles are warned or punished through data screening. Electronic police are divided into intersection electric police and road section electric police. The scene is large and the snapshots are composed of multiple photos to reflect the violation process. Referring to Figure 2, when the camera 900 is used in the working environment of the electric police camera, it is often used to take pictures of passing vehicles at road intersections. For example, it is set at the intersection to take pictures of whether the vehicles waiting for the red light are crossing the line, or if the on the road When photographing whether there are illegally parked vehicles in areas such as the side, the strong light source 700 is mainly the sun. High-intensity sunlight will cause a "ghost" phenomenon in the imaging of the electric police camera.

This application provides an implementation of a camera module. As shown in FIGS. 3 and 4 , the camera module includes a window 100 , a lens module 200 , a first bracket 300 and a second bracket 400 . The window 100 is located on the light incident side of the lens module 200. The incident light passes through the window 100 and then enters the lens module 200.

The first bracket 300 is connected to the window 100 . The first bracket 300 can be directly connected to the window 100, or indirectly connected to the window 100 through housing components such as the shield 600. In this embodiment, the first bracket 300 and the shield 600 are fixedly connected through captive screws. The window 100 is fixed on the light incident side of the shield 600 .

The second bracket 400 is connected to the lens module 200. Specifically, the lens module 200 includes optical components such as lenses, filter layers, and image sensors, and is provided with a lens housing to connect, fix, and protect the optical components. The optical element is installed in the lens housing to form a lens module 200 with an overall structure. The lens housing of the lens module 200 and the second bracket 400 are fixedly connected through captive screws.

The first bracket 300 and the second bracket 400 are connected, and form at least two assembly forms after being connected. Specifically, the first bracket 300 and the second bracket 400 can be two independent structures, and there are at least two assembly positions between the first bracket 300 and the second bracket 400. Different assembly positions form different assembly forms when assembled. Alternatively, the first bracket 300 and the second bracket 400 can relatively rotate after being connected and formed to form different assembly configurations. The specific implementation manner will be described in the following embodiments.

In this embodiment, no matter how the first bracket 300 and the second bracket 400 are connected, as long as the first bracket 300 and the second bracket 400 can be transformed into at least two assembly forms after being connected and formed, and in different forms , the angles formed between the optical axis 210 of the lens module 200 and the central axis 110 of the window 100 are different, and both fall within the protection scope defined by this application.

It should be understood that the optical axis 210 in this embodiment is a light ray that passes vertically through the center of the lens 220. When the multi-layer lenses 220 are provided in the lens module 200, the multi-layer lenses 220 are arranged parallel and concentrically, so that the light The axis 210 passes vertically through the center of each layer of lenses 220 . The central axis 110 in this embodiment is a vertical line passing through the center point of the window 100. When the window 100 is flat, the central axis 110 is perpendicular to the window 100; when the window 100 is an arc-shaped structure, the window 100 is in the center. The tangent plane at the point is perpendicular to the central axis 110. The window 100 is located on the light incident side of the lens module 200 to protect the lens module 200. In order to prevent the light from changing through the window 100, in this embodiment, the window 100 is flat as an example, and the thickness of the window 100 is uniform, but it is not limited to The window described in this application is only flat-shaped, and any shape of the window 100 falls within the protection scope defined by this application.

Referring to FIGS. 5 and 7 , in the first form of the whole body formed after the first bracket 300 and the second bracket 400 are connected, a first included angle 440 is formed between the optical axis 210 and the central axis 110 . Wherein, the first included angle 440 in Figure 11 is 0 degrees, and the central axis 110 and the optical axis 210 are parallel or coincident.

It should be noted that when the technical solution of this application is used in actual products, due to reasons such as preparation accuracy, there may be a certain error between the first included angle 440 in the actual product and the first included angle 440 defined in this application. Refer to As shown in Figure 5, the first included angle 440 is 1 degree. Moreover, the first angle is the angle between the optical axis 210 and the central axis 110 , and the first angle 440 can also be converted by measuring the angle between the plane where the window 100 is located and the optical axis 210 . However, under the idea of the technical solution of this application, by setting the first bracket 300 and the second bracket 400 to form different shapes after being connected, the product can be adjusted to form different angles between the optical axis 210 and the central axis 110, even if the optical axis The angle between 210 and the central axis 110 is somewhat different from the specific angles of the first angle 440 and the second angle 450 described in this application, and both fall within the protection scope defined by this application.

Specifically, this embodiment explains the structure and optical path direction of the camera module in two forms to clearly describe the two types of The camera module in this form eliminates "ghosting" when facing different working environments. It should be noted that this embodiment only takes two working environments as examples, and only shows the camera module in two forms. Under the technical idea of this embodiment, the camera module can be provided with more than two different forms. .

Referring to FIG. 11 , in the first form, the central axis 110 and the optical axis 210 are parallel. When the camera module in this form is used in a working environment of an electric police camera, the strong light source 700 is mainly the sun located obliquely above the camera module, and the strong light source beam 710 passes through the window 100 obliquely. The main beam 720 of the beam 710 passes through the lens 220 and forms an image point A in the image sensor, which is the real imaging point of the strong light source. Part of the strong light source beam 710 is reflected by the lens 220 to form a primary reflected beam 730 , and the primary reflected beam 730 is reflected by the viewing window 100 to generate a secondary reflected beam 740 . At this time, the angle between the central axis 110 and the optical axis 210 is 0, and the plane where the window 100 is located and the plane where the lens 220 is located are parallel. The camera module is generally set at a higher position above the ground to capture images of a relatively low target area. When used, the camera module is usually tilted downward to capture the target area, and the strong light source 700 emitted by the sun is emitted into the lens module. The angle of the group 200 is relatively large, causing the secondary reflected beam 740 to deviate from the lens 220 of the lens module 200. The secondary reflected beam 740 does not enter the lens module 200, and thus does not cause image B in the imaging sensor, effectively avoiding The occurrence of "ghosting" phenomenon, when using the electric police style camera in the working environment in the first form, the sun as a strong light source will not cause "ghosting" phenomenon during imaging.

However, as shown in FIG. 12 , in the first form, the central axis 110 and the optical axis 210 are parallel. When the camera module in this form is used in the working environment of a bayonet type surveillance camera, the strong light source 700 is mainly a car headlight located diagonally below the camera module, and the strong light source beam 710 passes upward through the window 100. Primary beam 720 passes through lens 220 and forms image point A within the image sensor. Due to the reflection effect of the lens 220 and the viewing window 100, part of the strong light source beam 710 is reflected by the lens 220 to form a primary reflected beam 730. The primary reflected beam 730 is reflected by the viewing window 100 to generate a secondary reflected beam 740. When used in the working environment of bayonet type surveillance cameras, the camera module still tilts downward to obtain images of the target area. In the first form, the central axis 110 and the optical axis 210 are parallel. Compared with the working environment of the electric police surveillance camera, the main beam 720 is tilted upward and injected into the lens module 200, and the secondary reflected beam 740 enters the lens 220. , and image point B is formed in the image sensor. Image point B is the "ghost" on the side of image point A in the imaged image.

The camera in the first form is suitable for the working environment of electric police cameras and will not cause "ghosting" phenomena. When the camera in the first form is used in the working environment of a bayonet camera, a "ghosting" phenomenon will occur, affecting the imaging quality. When the bayonet camera is used in a working environment, the first bracket 300 and the second bracket 400 can be changed to the second shape.

Referring to FIGS. 6 and 8 , the whole formed by connecting the first bracket 300 and the second bracket 400 is in the second form. At this time, a second included angle 450 is formed between the optical axis 210 and the central axis 110 . The first included angle 440 in FIG. 13 is 8 degrees. At this time, the central axis 110 and the optical axis 210 form an included angle of 8 degrees.

Referring to FIG. 13 , in the second form, the central axis 110 and the optical axis 210 form an included angle of 8 degrees. When the camera module in this form is used in the working environment of a bayonet camera, the strong light source 700 is mainly a car headlight located obliquely below the camera module. The strong light source beam 710 passes through the window 100 obliquely. The main beam 720 of the beam 710 passes through the lens 220 and forms an image point A in the image sensor, which is the real imaging point of the strong light source. Due to the reflection effect of the lens 220 and the viewing window 100, part of the strong light source beam 710 is reflected by the lens 220 to form a primary reflected beam 730. The primary reflected beam 730 is reflected by the viewing window 100 to generate a secondary reflected beam 740. At this time, the angle between the central axis 110 and the optical axis 210 is 8 degrees. Due to the different setting angles of the lens module 200 for acquiring the target area, compared with the morphological diagram shown in Figure 12, the window shown in Figure 13 Compared with the window 100 shown in Figure 12, the window 100 is rotated 8 degrees in the counterclockwise direction, so that the secondary reflected beam 740 deviates from the lens 220 of the lens module 200, and the secondary reflected beam 740 will not enter the lens module 200. , and thus no imaging B will appear in the imaging sensor, effectively avoiding the "ghost" phenomenon. In the second form When using a bayonet camera in a working environment, car headlights as a strong light source will not cause "ghosting" during imaging.

When the camera module described in this application is used in different working environments and faces strong light source incident angles from different directions, the camera module can be adjusted by switching the connected and formed shapes of the first bracket 300 and the second bracket 400 . The relative angle between the axis 110 and the optical axis 210 ensures that the secondary reflected light beam formed by the reflection of the strong light source through the lens and the window can deviate from the lens and not be imaged on the imaging sensor, thus avoiding the phenomenon of "ghosting". The camera module described in this application can avoid the "ghosting" phenomenon under different incident directions of strong light sources, and improves the versatility of camera products produced on the same platform. The same camera can switch between the first bracket 300 and the second bracket 300 . The connected form of the bracket 400 is used to obtain high-quality images in various working environments.

It can be understood that, as shown in FIG. 14 , when the camera module in the second form is used in the working environment of an electric police camera, the strong light source 700 is mainly the sun located obliquely above the camera module. The strong light source The beam 710 passes obliquely downward through the window 100. The main beam 720 of the strong light source beam 710 passes through the lens 220 and forms an image point A in the image sensor. The image point A is the real imaging point of the strong light source. Part of the strong light source beam 710 is reflected by the lens 220 to form a primary reflected beam 730 , and the primary reflected beam 730 is reflected by the viewing window 100 to generate a secondary reflected beam 740 . At this time, the angle between the central axis 110 and the optical axis 210 is 8, and the secondary reflected beam 740 will enter the lens module 200, and then image B will appear in the imaging sensor, and a "ghost" phenomenon will occur. When using the bayonet camera in the second mode, the sun as a strong light source will reappear the "ghosting" phenomenon during imaging. When the camera module is used in the working environment of an electric police camera, the "ghost" phenomenon can be avoided by switching the molded form after the first bracket 300 and the second bracket 400 are connected from the second form to the first form. .

It should be noted that, referring to FIGS. 5 and 6 , the camera module described in this embodiment and the following embodiments, the camera module in the second form is smaller than the camera module in the first form. The lens module 200 is tilted upward relative to the central axis 110 of the window 100. This is only because the camera module in the first form of this embodiment is suitable for working environments where strong light sources such as sunlight are above, and the camera module in the second form is suitable for Suitable for working environments where strong light sources such as car lights are below. When strong light sources in different environments are incident from the side, above the side, and below the side, the optical axis 210 of the camera module in different forms can be tilted laterally relative to the central axis 110 .

In a possible implementation, the range of the first included angle 440 includes: 0 degrees - 3 degrees (including the two end values of 0 degrees and 3 degrees). In the first form, the camera module uses an electric police model. There will be no "ghosting" phenomenon when the camera working environment faces the strong light of the sun; the second included angle 450 is greater than or equal to 5 degrees. In the second form, the camera module uses a bayonet style camera working environment facing the car There will be no "ghosting" phenomenon when turning on the headlights.

In a possible implementation, the first bracket 300 and the second bracket 400 form the first form and the second form by providing multiple assembly positions.

Referring to FIG. 7 , the first bracket 300 is provided with a first mounting part 310 and a second mounting part 320 , and the second bracket 400 is provided with a third mounting part 410 .

The first mounting part 310 and the second mounting part 320 have the same structure and size, but the positions of the first mounting part 310 and the second mounting part 320 are different. The first mounting part 310 and the third mounting part 410 are connected to each other in a first assembly direction, and the second mounting part 320 and the third mounting part 410 are connected to each other in a second assembly direction. The first assembly direction and the second assembly direction The direction is different.

Referring to FIG. 7 , the first mounting part 310 and the third mounting part 410 are connected, so that the first bracket 300 and the second bracket 400 are assembled to form the first form. In the first form, the first assembly direction connected between the first mounting part 310 and the third mounting part 410 is perpendicular to the optical axis 210 , and the first assembly direction is perpendicular to the central axis 110 , so that the connection between the central axis 110 and the optical axis 210 is There is a first included angle 440 between them.

Referring to FIG. 8 , the second mounting part 320 and the third mounting part 410 are connected, so that the first bracket 300 and the second bracket 400 are assembled to form the second form. In the second form, the second assembly direction connected between the second mounting part 320 and the third mounting part 410 is perpendicular to the optical axis 210, and the second assembly direction forms a certain angle with the central axis 110, so that the central axis 110 and the optical axis 210 form a second included angle 450.

It should be noted that in this embodiment, with reference to FIGS. 7 and 8 , only an implementation of the first included angle 440 and the second included angle 450 is given as an example. In actual products, for different When facing strong light sources from different incident directions in a working environment, the first assembly direction and the second assembly direction can be set correspondingly to meet the needs under different conditions.

In this embodiment, multiple mounting parts are provided on the first bracket 300, and the different mounting parts of the first bracket 300 and the mounting parts of the second bracket 400 are assembled in different directions, so as to adjust the first bracket 300 and the second bracket 400 to different positions. Form combination. When facing strong light sources from different incident directions in different working environments, the angle between the optical axis 210 of the lens module 200 and the central axis 110 of the viewing window 100 can be adjusted by adjusting the matching relationship of the mounting parts to avoid the "ghosting" phenomenon. appears, the adjustment process is more convenient. Moreover, corresponding angles can be marked next to different installation positions on the first bracket 300. The corresponding angles are the angles between the optical axis 210 and the central axis 110 after the installation position and the installation position of the second bracket 400 are matched. The first bracket 300 and The installation and positioning of the second bracket 400 is faster and more convenient.

It can be understood that when more than two working environments need to be faced, more than two mounting parts can be provided on the first bracket 300, and each mounting part and the third mounting part 410 of the second bracket 400 have different assemblies. direction to adjust the optical axis 210 and the central axis 110 to form different angles.

The first mounting part 310 and the second mounting part 320 have the same structure and size, and are assembled in the same manner as the third mounting part 410. They may be detachable connections such as snap connections and screw connections, or may be realized by welding or other methods. Fixed connection.

In a possible implementation, the mounting portions on the first bracket 300 and the mounting portions on the second bracket 400 can exchange positions. The first mounting portion 310 and the second mounting portion 320 are located on the second bracket 400. The mounting part 410 is located on the first bracket 300 .

In a possible implementation, as shown in FIGS. 5-10 , along the third direction 211 , the first mounting part 310 is located on one side of the second mounting part 320 . The first mounting part 310 is located on one side of the second mounting part 320 along the third direction 211 .

Among them, the optical axis 210 of the lens module 200 is a light ray that passes vertically through the center of the lens. Refer to Figures 9 and 10. The third direction 211 is: on the light incident side of the lens module 200, in the second form. The offset direction of the optical axis 210 relative to the optical axis 210 in the first form.

Since the first bracket 300 and the window 100 are relatively fixed, when the first bracket 300 and the second bracket 400 change shapes to drive the lens module 200 to rise upward and tilt relative to the window 100, the entrance of the lens module 200 The light-side end surface will rise to a certain height, so that the optical axis 210 on the light-incident side in the second form is tilted upward compared with the optical axis 210 on the light-incident side in the first form, which is equivalent to the optical axis 210 rotating clockwise.

Referring to Figure 9, the solid line part in Figure 9 is a schematic side view of the connection of the lens module 200, the first bracket 300 and the second bracket 400 in the second form; the dotted line part in Figure 9 is the first form. Schematic side view of the connection between the lens module 200, the first bracket 300 and the second bracket 400. On the light incident side of the lens module 200, the optical axis 210 in the second form is tilted upward at a certain angle compared to the optical axis 210 in the first form. Furthermore, the optical axis 210 in the second form is tilted upward compared to the optical axis 210 in the first form. The optical axis 210 of is offset along the third direction 211 (the direction shown in FIG. 9 is upward). At this time, the second mounting part 320 is located on the opposite side of the first mounting part 310 along the third direction 211, that is, the second mounting part 320 is located below the first mounting part 310, so as to rotate clockwise upward on the lens module 200. When , the lens module 200 as a whole is displaced downward, reducing the height of the assembly of the lens module 200 , the first bracket 300 and the second bracket 400 .

Among them, as shown in Figure 9, the lens module 200 includes components such as a lens lens 220 and an imaging sensor 230. The lens lens 220 is mainly composed of optical lenses such as lenses, and is located on the light incident side of the imaging sensor 230; the lens lens 220 needs to focus when photographing targets at different distances, so it can be fixed relative to the imaging sensor 230 with the optical axis 210 as the rotation axis. of rotation. However, the imaging sensor 230 is connected to a data line to be connected to a processing module such as the motherboard, and the motherboard is connected to a housing such as the shield 600. Therefore, the imaging sensor 230 is not suitable for rotation. The second bracket 400 is suitable for fixed connection with the imaging sensor 230 part. The lens The lens 220 is capable of relative rotation relative to the imaging sensor 230 . Since the length of the lens lens 220 along the optical axis is relatively long, when the imaging sensor 230 is driven upward by the second bracket 400 to rotate and lift, the lens lens 220 will be raised to a higher height.

Referring to FIG. 10 , if the second mounting part 320 is at the same horizontal position relative to the first mounting part 310 , or in other words, the second mounting part 320 is higher than the first mounting part 310 , it will cause the lens module 200 and the first bracket 300 to The assembly with the second bracket 400 will be raised to a higher height. If the light-incident side end surface of the lens module 200 is raised too high in the second form, on the one hand it will increase the overall height of the camera module, and even cause installation interference with the top inner wall surface of the housing such as the shield 600; on the other hand, it will increase the overall height of the camera module. On the other hand, if the light-incident end face of the lens module 200 is raised too high, the optical axis 210 of the lens module 200 will intersect with the top area of the window 100, or even the optical axis 210 will exceed the top of the window 100, resulting in a large beam in the target area. Part of it is blocked by the protective cover 600 on the outside of the viewing window, and the field of view of the lens module is blocked by the protective cover 600. There are dark corners in the image of the camera module, and the image is incomplete.

In this embodiment, the relative position of the first mounting part 310 and the second mounting part 320 is limited, so that the lens module 200 after switching the form is displaced in the opposite direction of the rotation direction. The lens module 200, the first bracket 300 and the second The overall assembly volume of the bracket 400 will not be too large, preventing the lens part of the lens module from increasing in height due to deflection and colliding with the inner wall of the housing such as the shield, preventing the field of view of the lens module from being blocked by the housing such as the shield, and preventing final imaging. Vignette appears.

In a possible implementation, as shown in Figures 7, 8, 15 and 16, the first bracket 300 and the second bracket 400 described in this embodiment are fixed by a fixing part 500, where the fixing part 500 can be It can be a screw or a connecting piece such as a rivet. In this embodiment, screws are used as an example, and the fixing member 500 is a captive screw.

The first mounting part 310 is provided with a first mounting hole 311, the second mounting part 320 is provided with a second mounting hole 321, and the third mounting part 410 is provided with a third mounting hole 411; the axial direction of the first mounting hole 311 is the third One direction 312, the axial direction of the second mounting hole 321 is the second direction 322, and the first direction 312 and the second direction 322 are different.

Specifically, the fixing component 500 may be a rivet or a connecting component such as a screw. In this embodiment, the fixing component 500 is a fixed screw as an example.

The first mounting hole 311 and the second mounting hole 321 are both provided with internal threads that match the screws. The third mounting hole 411 is a through hole, and the inner wall of the through hole can be smooth, or it can also be provided with internal threads that match the screws. The screw passes through the third mounting hole 411 and is inserted into the first mounting hole 311 , or the screw passes through the third mounting hole 411 and is inserted into the second mounting hole 321 to firmly connect the first bracket 300 and the second bracket 400 .

Referring to FIG. 15 , the fixing member 500 passes through the third mounting hole 411 and then is inserted into the first mounting hole 311 along the first direction 312 and is threadedly connected to the first mounting hole 311 . The first bracket 300 and the second bracket 400 that are matched and connected form a first shape, and a first included angle 440 is formed between the optical axis 210 and the central axis 110;

Referring to FIG. 16 , the fixing member 500 passes through the third mounting hole 411 and then is inserted into the second mounting hole 321 along the second direction 322 and is threadedly connected to the second mounting hole 321 . The second direction 322 is different from the first direction 312. The first bracket 300 and the second bracket 400 that are coupled together form a second form, and a second included angle 450 is formed between the optical axis 210 and the central axis 110.

In this embodiment, the connection is made through the cooperation of screws and mounting holes. The disassembly and assembly of the first bracket 300 and the second bracket 400 are more convenient, and the connection between the first bracket 300 and the second bracket 400 is more firm. Especially when the camera module is used on the road to shoot traffic conditions, the driving of the car will cause the camera module to vibrate to a certain extent. The captive screws can improve the connection firmness of the camera module and prevent the first bracket 300 from being damaged due to vibration. There is a wobble between the second bracket 400 and move.

Specifically, there are three first mounting holes 311 , second mounting holes 321 and third mounting holes 411 in this embodiment, and they are distributed in a triangular structure to improve the efficiency when connecting the first bracket 300 and the second bracket 400 . Connection robustness.

In a possible implementation, as shown in FIGS. 17 and 18 , the camera module further includes a sliding part. The sliding part includes a first sliding part 340 provided on the first bracket 300 and a sliding part 340 provided on the second bracket 400 . The second sliding part 430, the first sliding part 340 and the second sliding part 430 slide relative to each other along the predetermined trajectory 460 for sliding switching to other forms.

The first bracket 300 and the second bracket 400 slide relative to each other along the predetermined trajectory 460 , and are mutually limited in the lateral direction of the predetermined trajectory 460 , so that the first bracket 300 and the second bracket 400 only move relative to each other along the predetermined trajectory 460 . All are applicable to this implementation. For example, the sliding connection between the first sliding part 340 and the second sliding part 430 may be a sliding rail and a sliding block, or a sliding connection between a sliding rod and a sliding ring.

In this embodiment, by providing a sliding part, when the connecting mechanism of the first bracket 300 and the second bracket 400 is disassembled, the first bracket 300 and the second bracket 400 will not be separated due to external forces such as gravity, and the sliding part will guide the first bracket 300 and the second bracket 400. Under the influence, it can be switched to other modes along the predetermined trajectory 460. For example, when the first bracket 300 and the second bracket 400 are in the first form and the assembly fixings 500 of the first mounting hole 311 and the third mounting hole 411 are removed, the first bracket 300 and the second bracket 400 can move along the predetermined trajectory 460 Slide relatively and quickly to align the second mounting hole 321 and the third mounting hole 411. Connect the first bracket 300 and the second bracket 400 by assembling the fixing part 500. The first bracket 300 and the second bracket 400 switch to the second mounting hole 321 and the third mounting hole 411. form to achieve quick switching.

In one embodiment, in addition to sliding relative to each other along the first preset trajectory, the first sliding part 340 and the second sliding part 430 may also rotate relative to each other. Since the relative angles of the first bracket 300 and the second bracket 400 are different in different forms, a certain angle of relative rotation is required when switching between different forms. Referring to FIG. 17 , FIG. 17 shows the first bracket 300 and the second bracket 400 in the first form, in which the second bracket 400 and the lens module 200 are fixedly connected. Referring to FIG. 18 , FIG. 18 shows the first bracket 300 and the second bracket 400 in the second form, where the second bracket 400 and the lens module 200 are fixedly connected. In the second form, compared with the first form, the second bracket 400 tilts upward to the left relative to the first bracket 300. Therefore, when the first form is switched to the second form, the second bracket 400 moves smoothly relative to the first bracket 300. The relative rotation of the hour hands.

The first bracket 300 and the first sliding part 340 may form a rotating structure, and/or the second bracket 400 and the second sliding part 430 may form a rotating structure to ensure that the first bracket 300 and the second sliding part 340 are switched between different forms. The bracket 400 can rotate relatively. This embodiment optimizes and simplifies the structure between the first bracket 300 and the second bracket 400 through the design of relative rotation between the first sliding part 340 and the second sliding part 430. There is no need to provide other structures to realize the first bracket. 300 and the first sliding part 340 are relatively rotated, and there is no need to provide other structures to realize the relative rotation of the second bracket 400 and the second sliding part 430. The first sliding part 340 and the second sliding part 430 satisfy relative sliding and relative rotation at the same time. The function and structure are more optimized.

Referring to FIGS. 17 and 18 , the first sliding part 340 includes two opposite sliding grooves (not shown in the figures) or sliding holes 341 . Referring to FIGS. 7 and 8 , the first bracket 300 includes a bottom plate 370 and side plates 360 disposed on both sides of the bottom plate 370 . The side plates 360 are erected on both sides of the bottom plate 370 so that the first bracket 300 forms a U-shaped structure. . The second bracket 400 can be fixed in the U-shaped groove.

The sliding hole 341 is a through hole provided on the side plate 360 . In this embodiment, the sliding hole 341 is a long through hole, and the extending direction of the sliding hole 341 on the side plate 360 is the direction of the predetermined trajectory 460 . A sliding hole 341 is respectively provided on the two side plates 360, and the two sliding holes 341 are arranged opposite to each other.

When the first sliding part 340 is a chute, the setting position of the chute is the same as the setting position of the sliding hole 341, and the direction of the slot opening of the chute is toward the U-shaped groove of the first bracket 300, and the extending direction of the chute is the same as that of the sliding hole 341. The holes 341 extend in the same direction. Book The embodiment takes the sliding hole 341 as an example.

The second sliding part 430 includes two rotating shafts 431 disposed on both sides of the second bracket 400. The two rotating shafts 431 are respectively inserted into the two sliding holes 341 and can slide relatively along the extension direction of the sliding holes 341; and, the rotating shafts 431 can move in The sliding hole 341 rotates inward to achieve sliding and rotational connection between the first sliding part 340 and the second sliding part 430 .

It can be understood that the positions of the sliding hole 341 and the rotating shaft 431 in this embodiment can be reversed. The sliding hole 341 is located on both sides of the second bracket 400 and the rotating shaft 431 is provided on the side plate 360 of the first bracket 300 .

In this embodiment, the sliding hole 341 and the rotating shaft 431 are used to realize the sliding and rotational connection of the first sliding part 340 and the second sliding part 430. The structure is simple; during preparation, the sliding hole 341 only needs to be left during the compression molding of the first bracket 300. , and the rotating shaft 431 is prepared during the compression molding of the second bracket 400. The preparation process is simple, the cost is low, and the structural strength after molding is high.

In a possible implementation, the chute or sliding hole 341 is provided with a limiting portion 342. In the first form or the second form, the limiting portion 342 is used to adjust the first sliding portion 340 and the second sliding portion 430. The relative sliding between them is limited. Referring to Figures 17 and 18, the limiting portion 342 is a turning hole formed by extending downward from the rightmost end of the sliding hole 341. That is, when the rotating shaft 431 slides to the rightmost side along the sliding hole 341, it will be stuck under the action of gravity. In the turning hole, the first bracket 300 and the second bracket 400 form the second shape at this time. The turning hole limits the position of the rotating shaft 431. When switching from the second form to the first form, the second bracket 400 needs to be lifted upward. Only after the rotating shaft 431 is lifted upward and out of the turning position can the rotating shaft 431 slide to the position corresponding to the first form. . The limiting part described in this embodiment can limit the position of the rotating shaft 431 when the first bracket 300 and the second bracket 400 are in the assembly position of the target shape, thereby realizing the rapid positioning of the first bracket 300 and the second bracket 400 and facilitating the second bracket 300 and the second bracket 400. Installation of the first bracket 300 and the second bracket 400 .

In a possible implementation, the first bracket 300 and the second bracket 400 form the first shape and the second shape by providing a rotational connection mechanism.

Referring to Figures 19 and 20, a first rotating part 330 is provided on the first bracket 300, and a second rotating part 420 is provided on the second bracket 400. The first rotating part 330 and the second rotating part 420 are rotationally connected.

Among them, the first rotating part 330 and the second rotating part 420 can be implemented in various ways, and can rotate relative to each other to realize the relative rotation of the first bracket 300 and the second bracket 400. In this embodiment, the first rotating part 330 takes the rotating hole provided on the side plate 360 as an example, and the second rotating part 420 takes the rotating shaft on the side of the second bracket 400 as an example.

The rotating shaft is inserted into the rotating hole to achieve a rotational connection to achieve a rotational connection between the first bracket 300 and the second bracket 400. By adjusting the rotation angles of the first bracket 300 and the second bracket 400 to different shapes, the optical axis of the lens module 200 is adjusted. 210 and the central axis 110 of the window 100 to eliminate the "ghosting" phenomenon.

Specifically, when the first rotating part 330 and the second rotating part 420 rotate relative to the first relative angle, the whole formed by the first bracket 300 and the second bracket 400 assumes the first shape, and the optical axis 210 and the central axis 110 form a The first included angle is 440. Referring to Figures 19 and 11, the camera module in the first form can avoid the "ghosting" phenomenon when used in the working environment of an electric police camera.

Specifically, when the first rotating part 330 and the second rotating part 420 rotate relative to the second relative angle, the whole formed by the first bracket 300 and the second bracket 400 assumes the second shape, and the optical axis 210 and the central axis 110 form a The second included angle is 450. As shown in Figure 13, the camera module in the second form can avoid the "ghosting" phenomenon when used in the working environment of a bayonet camera.

Specifically, as shown in FIG. 20 , the camera module in this embodiment is also provided with a sliding part. The sliding part includes a first sliding part 340 provided on the first bracket 300 , and also includes a first sliding part 340 provided on the second bracket 400 . the second sliding part 430. The first sliding part 340 is an arc-shaped through hole, and the center of the arc-shaped through hole coincides with the relative rotation axis of the first rotating part 330 and the second rotating part 420 . The second sliding part 430 is a screw, and the screw passes through the arc-shaped through hole and is threadedly connected to the second bracket 400 .

When the first bracket 300 and the second bracket 400 rotate relative to the first relative angle or the second relative angle, tighten the screws to It is threadedly connected to the second bracket 400, and the screw and the second bracket 400 clamp the side plate 360 of the first bracket 300 to achieve a fixed connection between the first bracket 300 and the second bracket 400. When the thread tightening force of the screw and the second bracket 400 is loosened, the screw and the second bracket 400 no longer exert a clamping force on the side plate 360 , and the first bracket 300 and the second bracket 400 return to their free state and can rotate relative to each other until they are opposite to each other. When rotating to the second relative angle, re-tighten the screws to achieve relative fixation of the first bracket 300 and the second bracket 400 in the second form.

In a possible implementation, when the first bracket 300 and the second bracket 400 are rotationally connected to form the first form and the second form, as shown in Figure 21, the camera module further includes a drive module 800, and the drive module 800 The drive shaft 810 and the second bracket 400 are fixedly connected. Specifically, in Figure 21, the driving shaft 810 is connected to the second rotating part 420 to drive the second rotating part 420 to rotate. The corresponding driving module 800 body can be fixedly connected to the first bracket 300. When the driving shaft 810 rotates, it can drive the second rotating part 420 to rotate relative to the first rotating part 330 to drive the first bracket 300 and the second bracket 400 to rotate in the first position. Switch between the first form and the second form.

Similarly, the driving shaft 810 of the driving module 800 can also be connected to the first bracket 300 , and the corresponding driving module 800 body can be fixedly connected to the second bracket 400 . For example, the body of the driving module 800 is fixedly connected to the first bracket 300, the driving shaft of the driving module 800 is inserted into the rotating hole of the second rotating part 420, and the driving shaft and the rotating hole are fixed without relative rotation.

Referring to FIG. 22 , the shield 600 is provided with at least two connecting mechanisms 610 for connecting the first bracket 300 . In this embodiment, the first bracket 300 and the shield 600 are connected by two screws on both sides in the width direction, and the connection mechanism 610 includes two screw holes. In this embodiment, FIG. 22 shows that three sets of connection mechanisms 610 are provided on one side of the shield, and a total of six sets of connection mechanisms 610 are provided on the shield.

When the shield 600 and the first bracket 300 are in different assembly positions, the first bracket 300 is connected to different connecting mechanisms 610, and the lens distance between the window 100 and the lens module 200 is different in different assembly positions.

It should be noted that the lens distance described in this embodiment refers to the distance between the center point of the window 100 and the center point of the light-incident side lens of the lens module 200 along the direction of the central axis 110 .

When the first bracket 300 and the second bracket 400 switch forms, the relative angle of the lens module 200 and the window 100 changes, and the relative position of the lens module 200 and the shield 600 also changes. When the camera is in use, the shield is fixed on the working position. After switching the form, the distance between the shield and the target area changes little, while the distance between the lens module 200 and the target area changes greatly. By adjusting the lens distance between the lens module 200 and the window 100, the lens module can be facilitated to focus to obtain a clear image of the target area.

In one embodiment, the camera further includes a sliding mechanism. Refer to Figures 22 and 3. The sliding mechanism includes a first sliding mechanism 620 provided on the shield 600 and a second sliding mechanism 350 provided on the first bracket 300. .

The second sliding mechanism 350 includes a sliding table disposed on the side of the first bracket 300 . Since the first bracket 300 is connected to the second bracket 400, the second bracket 400 is connected to the lens module 200, and the lens module 200 is also connected to the fixed motherboard through a data cable, when the installation position of the first bracket 300 is changed, the lens module The assembly 200 will not break away from the supporting function of the shield 600 to prevent the lens module 200 from being damaged by tipping or falling. In particular, when adjusting the lens distance between the lens module 200 and the window 100 at the camera's working station, which is mostly on a truss nearly 10 meters high, if the lens module 200 falls to the ground, serious consequences may occur. Damage, or even irreparable damage, the sliding method of the first bracket 300 and the shield 600 improves the safety of camera assembly and debugging.

In one embodiment, the camera further includes an image processor, and the camera module is electrically connected to the image sensor. After the image sensor in the camera module acquires the image data of the target area, the image sensor processes the acquired image data to obtain the final target area image.
