Abstract
Description
Technical Field
[0001] The present application relates to the technical field of vehicle-mounted equipment, and in particular to a mounting unit, a camera module and a vehicle. Background Art
[0002] In recent years, with the development of science and technology and the improvement of people's living standards, cars have become more and more popular. In order to pursue better driving experience and higher safety requirements, camera modules with cameras have begun to be widely used in cars.
[0003] At present, a camera module includes at least one lens and a shell. At least one lens is mounted on the shell and is installed on a car through the shell. There are two ways to install the existing camera relative to the car. One is that the camera is rigidly fixed directly on the car through the shell. However, due to assembly errors, the software related to the camera cannot be calibrated. At the same time, the rigid connection also makes it impossible to adjust the field of view, affecting the normal operation of the camera module; the second is that the camera angle is adjustably installed on the car through the shell. However, when the car drives on a bumpy road or a collision occurs and acceleration is generated, the angle of the camera is prone to change, affecting the subsequent use of the camera module. Utility Model Content
[0004] In view of the above, it is necessary to propose a mounting unit, a camera module and a car, so as to realize that the camera module can be angle-adjustable and the camera angle remains unchanged when subjected to external force, while improving the stability of the angle adjustment.
[0005] The present application provides an installation unit, comprising:
[0006] A bracket having a rotation axis, the bracket is provided with a first through hole and a second through hole, the first through hole is connected to the second through hole, and the axis of the first through hole does not intersect with the rotation axis and is perpendicular to each other;
[0007] A shell having an angle adjustment hole opposite to the first through hole, wherein the shell is rotatably mounted on the bracket around the rotation axis;
[0008] an angle adjustment member, one end of which passes through the first through hole and is locked in the angle adjustment hole, and is used to make the housing rotate around the rotation axis;
[0009] an elastic member, wherein the elastic member is disposed between the bracket and the housing, and two ends of the elastic member are respectively abutted against the bracket and the housing; and
[0010] A limiting member, wherein the limiting member passes through the second through hole and is inserted into the first through hole, and one end of the limiting member inserted into the first through hole is located on a side of the angle adjusting member away from the shell, so as to prevent the angle adjusting member from being disengaged from the first through hole.
[0011] The above-mentioned installation unit adjusts the angle adjustment member along the direction from the bracket to the shell. The shell has a tendency to move toward the direction close to the bracket under the connection between the angle adjustment hole and the angle adjustment member, and will rotate with the rotation axis as the rotation axis to achieve the shell to swing upward at a certain angle relative to the bracket; the angle adjustment member is adjusted along the direction from the bracket to the shell. The shell has a tendency to move toward the direction away from the bracket under the connection between the angle adjustment hole and the angle adjustment member, and will rotate with the rotation axis as the rotation axis to achieve the shell to swing downward at a certain angle relative to the bracket. At the same time, since one end of the limiter inserted into the first through hole is located on the side of the angle adjustment member away from the shell, when the angle adjustment member is adjusted, the angle adjustment member is blocked in the first through hole by the stopping action of the limiter, thereby stopping the angle adjustment member from detaching from the first through hole and sliding along the adjustment direction during adjustment; the elastic member plays a role in supporting the shell, and provides a tendency to move the shell away from the bracket when the shell is impacted by an external force, so that the shell and the bracket maintain a relatively fixed angle, avoiding the shell from rotating relative to the bracket when subjected to an external force, playing a role in buffering vibration, and ensuring the stability between the shell and the bracket. Therefore, by adjusting the angle adjustment member, the position of the shell and the lens installed on the shell can be adjusted relative to the bracket and the car, which is convenient for lens calibration, and the shell and the lens can be swung up and down to facilitate adjustment of the field of view of the lens. The setting of the limit member can prevent the angle adjustment member from detaching from the first through hole, thereby improving the stability of the angle adjustment. At the same time, the setting of the elastic member can support the shell and buffer vibration, thereby ensuring that the angle of the shell and the lens is fixed.
[0012] In one embodiment, the angle adjustment hole is a threaded hole, and the angle adjustment member has a coaxially arranged threaded section and an abutment section, the threaded section is threadedly engaged with the angle adjustment hole, and the abutment section abuts against the bracket; wherein one end of the limit member inserted into the first through hole is located on the side of the abutment section away from the threaded section.
[0013] The above-mentioned installation unit, by limiting the structure of the angle adjustment piece and the type of the angle adjustment hole, makes the shell have a tendency to move away from the bracket or towards the bracket under the action of the threaded connection between the angle adjustment hole and the angle adjustment piece, and will rotate around the rotation axis to achieve the shell swinging downward or upward at a certain angle relative to the bracket.
[0014] In one embodiment, the hole wall of the first through hole has a first curved surface, the abutting section has a protrusion, the outer surface of the protrusion contacting the hole wall of the first through hole is a spherical surface, and the side of the protrusion facing away from the threaded section is a plane.
[0015] The mounting unit can achieve smooth angle adjustment with a simple structure by defining the shapes and specific structures of the relative surfaces of the first through hole and the abutment section of the angle adjustment member.
[0016] In one of the embodiments, the angle adjustment member further includes a twisting section, and the twisting section, the abutting section and the threaded section are coaxially arranged, and the twisting section is located on a side of the abutting section away from the threaded section and is spaced apart from the limiting member.
[0017] The mounting unit is provided with a twisting section so that the angle adjusting member can be screwed in and out through the twisting section to adjust the position of the housing and the lens mounted on the housing relative to the bracket and the car.
[0018] In one embodiment, the first through hole is perpendicular to the second through hole, or the angle between the extension direction of the first through hole and the extension direction of the second through hole is an acute angle.
[0019] The above-mentioned installation unit limits the first through hole to be perpendicular to the second through hole, the limiting member is a screw, and the second through hole is a threaded hole. The limiting member can be easily screwed into the second through hole and is not easy to fall off, so as to prevent the angle adjustment member from being excessively screwed out and falling off through a simple structure.
[0020] In one of the embodiments, in the axial direction of the angle adjustment member, the distance between the rotation center of the angle adjustment member and the rotation axis is less than or equal to 0.04 mm.
[0021] The installation unit limits the distance between the rotation center of the angle adjustment member and the rotation axis so that the rotation centers of the angle adjustment member and the housing are closer, so as to better adjust the angle of the housing.
[0022] In one embodiment, an accommodating space is formed on opposite end surfaces of the shell and the bracket, and the elastic member is sleeved on the angle adjustment member and partially accommodated in the accommodating space.
[0023] The installation unit limits the setting position of the elastic member, so as to facilitate the installation of the elastic member and ensure the stability of the elastic member during the entire working process.
[0024] In one embodiment, the mounting unit further comprises two pins, wherein:
[0025] The housing comprises a housing body and two first plates, wherein the first plates are protrudingly arranged on both sides of the housing body along the extending direction of the rotation axis, and the first plates are perpendicular to the rotation axis, and the two first plates are correspondingly provided with third through holes;
[0026] The bracket is provided with fourth through holes corresponding to the third through holes on both sides along the rotation axis direction;
[0027] The pin shaft is inserted into the third through hole and the fourth through hole so that the housing can rotate around the rotation axis.
[0028] The mounting unit is configured by defining the structure of the housing and the bracket and arranging a pin shaft so that the housing can be rotatably mounted on the bracket.

[0030] In the above-mentioned camera module, since the angle adjustment member is adjusted in the mounting unit along the direction of the bracket toward the shell, the shell has a tendency to move toward the direction close to the bracket under the connection between the angle adjustment hole and the angle adjustment member, and will rotate with the rotation axis as the rotation axis to achieve the shell to swing upward at a certain angle relative to the bracket; the angle adjustment member is adjusted along the direction of the bracket away from the shell, and the shell has a tendency to move in the direction away from the bracket under the connection between the angle adjustment hole and the angle adjustment member, and will rotate with the rotation axis as the rotation axis to achieve the shell to swing downward at a certain angle relative to the bracket. At the same time, since one end of the limiter inserted into the first through hole is located on the side of the angle adjustment member away from the shell, when the angle adjustment member is adjusted, the angle adjustment member is blocked in the first through hole by the stopping action of the limiter, thereby stopping the angle adjustment member from detaching from the first through hole and sliding along the adjustment direction during adjustment; the elastic member plays a role in supporting the shell, and provides a tendency to move the shell away from the bracket when the shell is impacted by an external force, so that the shell and the bracket maintain a relatively fixed angle, avoid the shell from rotating relative to the bracket when subjected to an external force, play a role in buffering vibration, and ensure the stability between the shell and the bracket. Therefore, the camera module with the mounting unit can realize the up and down swing of the lens, which is convenient for lens calibration and field of view adjustment, and the angle of the lens will not change even if the car drives on a bumpy road or collides and generates acceleration, and the stability is good.
[0031] In addition, the present application also provides a car, which includes a body and the camera module as described above, and the camera module is installed on the body.
[0032] For the above-mentioned car, since the camera module can realize the up and down swing of the lens, it is convenient for lens calibration and field of view adjustment, and the angle of the lens will not change even when the car drives on a bumpy road or collides and generates acceleration, and the stability is good. Therefore, the car with the camera module has a better image acquisition effect, and has a better driving experience and safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0088] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.
[0089] See also Figure 1 The first embodiment of the present application provides a mounting unit 100, which is used to mount a lens 200 (such as Figure 8 As shown) is installed on the car, in the specific setting, the lens 200 and the mounting unit 100 are installed to form a camera module 1 (as shown Figure 8 and then secure it to the car.
[0090] Please also read Figure 2 , Figure 3 , Figure 4 and Figure 5 The mounting unit 100 includes a bracket 10, a housing 20, an angle adjustment member 30, an elastic member 40 and a stopper 50. The bracket 10 has a rotation axis 11, which is formed by connecting the holes or axes on the bracket 10. For example, a hole or an axis is provided at each end of the bracket 10, and the two holes or axes extend in the same direction and are on the same straight line, thereby forming the rotation axis 11. The bracket 10 is provided with a first through hole 12 and a second through hole 13, the first through hole 12 and the second through hole 13 are connected, the axis of the first through hole 12 does not intersect with the rotation axis 11 and is perpendicular to each other, the first through hole 12 is opened at the bracket 10 and penetrates the bracket 10 along the thickness direction, and the second through hole 13 is opened at the bracket 10 and is opened along a direction perpendicular to the thickness direction. In the specific setting, the material of the bracket 10 can be ADC-12 aluminum alloy (also known as No. 12 aluminum material, Al-Si-Cu alloy, and the implementation standard is: JIS H 5302-2006 "Aluminum Alloy Die Casting"), etc., to ensure the structural strength of the bracket 10. The axis of the first through hole 12 is not coaxial with the rotation axis 11, and the axis of the second through hole 13 is not coaxial with the axis of the first through hole 12 and the rotation axis 11. In the specific setting, the bracket 10 is installed on the car, the axis of the first through hole 12 and the rotation axis 11 do not intersect and can be perpendicular to each other to ensure the smooth adjustment process of the housing 20, and the axis of the second through hole 13 and the axis of the first through hole 12 and the rotation axis 11 can be perpendicular to each other, so as to install the limit member 50 to form a stop for the angle adjustment member 30. Among them, perpendicular to each other can be understood as that the angle between the axes is not necessarily 90°, for example, it can be between 85° and 95°. In some embodiments, the angle between the axis of the second through hole 13 and the extending direction of the axis of the first through hole 12 may also be an acute angle.
[0091] The shell 20 is provided with an angle adjustment hole 21 opposite to the first through hole 12, and the angle adjustment hole 21 is opened on the shell 20 and penetrates the shell 20 along the thickness direction. In a specific setting, the shell 20 has at least one mounting position 22, and the mounting position 22 is used to accommodate the lens 200. The material of the shell 20 can be ADC-12 aluminum alloy, etc., to ensure structural strength. The number of mounting positions 22 can be one, two, three or more than three, and can be specifically set according to actual needs. Multiple mounting positions 22 correspond to multiple lenses 200 to meet image acquisition requirements. The shell 20 is installed on the bracket 10, and the shell 20 is rotatably installed on the bracket 10 around the rotation axis 11. There is a gap between the shell 20 and the bracket 10, so that the shell 20 can rotate relative to the bracket 10. In a specific setting, the lens 200 is installed on the mounting position 22 of the shell 20, the shell 20 is rotatably installed on the bracket 10, and the bracket 10 is installed on the car to realize the rotatable connection of the lens 200 relative to the car.
[0092] One end of the angle adjustment member 30 passes through the first through hole 12 and is locked in the angle adjustment hole 21. The angle adjustment member 30 is used to rotate the housing 20 around the rotation axis 11, which can also be understood as making the housing 20 move closer to or farther away from the bracket 10 around the rotation axis 11. In a specific setting, the angle adjustment member 30 has a coaxially arranged threaded section 31 and an abutment section 32. The threaded section 31 passes through the first through hole 12 to be inserted into the angle adjustment hole 21, and the threaded section 31 is threadedly engaged with the angle adjustment hole 21, and the abutment section 32 abuts against the bracket 10, and the angle adjustment hole 21 is a threaded hole. In a specific setting, the material of the angle adjustment member 30 can be stainless steel, etc., to meet the requirements of waterproof and corrosion resistance. The angle adjustment member 30 can be a screw, a screw, etc., and can also be other structural forms that can meet the requirements.
[0093] The elastic member 40 is arranged between the bracket 10 and the shell 20, and the two ends of the elastic member 40 are respectively abutted against the bracket 10 and the shell 20. In the specific arrangement, the elastic member 40 is configured to be in a pre-compressed state, so that the shell 20 has a tendency to move away from the bracket 10, thereby ensuring that the shell 20 can be rotated around the rotation axis 11 by adjusting the angle adjustment member 30. The elastic member 40 can be a spring, an elastic pad, etc. The material of the spring can be piano wire, etc., and can also be other structural forms that can meet the requirements. The elastic member 40 can be directly abutted between the opposite surfaces of the bracket 10 and the shell 20, and the elastic member 40 can also be fixedly connected between the opposite surfaces of the bracket 10 and the shell 20 to prevent the elastic member 40 from detaching from between the bracket 10 and the shell 20 to ensure the stability of the overall structure.
[0094] The limiting member 50 passes through the second through hole 13 and is inserted into the first through hole 12. One end of the limiting member 50 inserted into the first through hole 12 is located on the side of the abutting section 32 away from the threaded section 31, and an adjustment space 60 is formed between the abutting section 32. It can also be understood that one end of the limiting member 50 inserted into the first through hole 12 is located on the side of the angle adjustment member 30 away from the shell 20, and an adjustment space 60 is formed between the angle adjustment member 30. The adjustment space 60 facilitates providing space for the angle adjustment member 30 to enter and exit. The material of the limiting member 50 can be carbon steel, etc., and can also be other structural forms that can meet the requirements. During the specific setting, the angle adjustment member 30 is passed through the first through hole 12 and locked to the angle adjustment hole 21, and then the limiting member 50 is passed through the second through hole 13 and inserted into the first through hole 12. The limiting member 50 can be a screw, and the second through hole 13 can be a threaded hole, so that the limiting member 50 can be more easily threadedly engaged with the second through hole 13, while ensuring that the limiting member 50 is not easy to fall off from the second through hole 13, thereby ensuring the stability of the overall structure.
[0095] The above-mentioned installation unit 100 is screwed into the angle adjustment member 30 along the direction of the bracket 10 toward the shell 20. Under the action of the threaded connection between the angle adjustment hole 21 and the angle adjustment member 30, the shell 20 has a tendency to move toward the direction close to the bracket 10, and will rotate around the rotating shaft 11 to achieve the shell 20 swinging upward at a certain angle relative to the bracket 10. The angle adjustment member 30 is unscrewed in the direction where the bracket 10 is away from the shell 20. Since the abutment section 32 abuts against the bracket 10, the shell 20 has a tendency to move in the direction away from the bracket 10 under the threaded connection between the angle adjustment hole 21 and the threaded section 31, and will rotate around the rotation axis 11 to achieve a downward swing of the shell 20 relative to the bracket 10 at a certain angle. At the same time, since one end of the limiting member 50 inserted into the first through hole 12 is located on the side of the abutment section 32 away from the threaded section 31, when the angle adjustment member 30 is unscrewed, the abutment section 32 of the angle adjustment member 30 is blocked in the first through hole 12 by the stopping action of the limiting member 50, thereby preventing the angle adjustment member 30 from disengaging from the first through hole 12 and sliding down in the unscrewing direction when it is unscrewed. The elastic member 40 plays a role in supporting the housing 20, and provides a tendency to move the housing 20 away from the bracket 10 when the housing 20 is impacted by an external force, so that the housing 20 and the bracket 10 maintain a relatively fixed angle, and avoid the housing 20 from rotating relative to the bracket 10 when subjected to an external force, and plays a role in buffering vibrations, thereby ensuring the stability between the housing 20 and the bracket 10. Therefore, by adjusting the angle adjustment member 30, the position of the housing 20 and the lens 200 mounted on the housing 20 is adjusted relative to the bracket 10 and the car, which is convenient for calibrating the lens 200, and the housing 20 and the lens 200 are made to swing up and down, which is convenient for adjusting the field of view of the lens 200. The setting of the limit member 50 can prevent the angle adjustment member 30 from being rotated out too much and disengaged from the first through hole 12, thereby improving the stability of the angle adjustment. At the same time, the setting of the elastic member 40 can support the housing 20 and buffer vibrations, thereby ensuring that the angle of the housing 20 and the lens 200 are fixed.
[0096] In order to facilitate the adjustment of the angle of the housing 20, a preferred embodiment is shown in FIG. Figure 4 , in the axial direction of the angle adjusting member 30, the distance D between the rotation center A of the angle adjusting member 30 and the rotation axis 11 may be less than or equal to 0.04 mm. In specific settings, the distance D between the rotation center A of the angle adjusting member 30 and the rotation axis 11 may be 0, 0.005 mm, 0.01 mm, 0.015 mm, 0.02 mm, 0.025 mm, 0.03 mm, 0.035 mm, 0.04 mm, etc.
[0097] The above-mentioned mounting unit 100 limits the distance D between the rotation center A of the angle adjustment member 30 and the rotating shaft 11 to be less than or equal to 0.04 mm, so that the distance D between the rotation center A of the angle adjustment member 30 and the rotating shaft 11 is smaller, the rotation center A of the angle adjustment member 30 and the shell 20 are closer, and the axial difference between the axis of the angle adjustment member 30 and the rotating shaft 11 is reduced, and even in the axial direction of the angle adjustment member 30, the distance between the rotation center A and the rotating shaft 11 is 0, and there is no axial difference between the axis of the angle adjustment member 30 and the rotating shaft 11, so as to better realize the adjustment of the angle of the shell 20, and the process of adjusting the angle of the shell 20 is smoother.
[0098] In order to ensure that the angle adjustment process is relatively smooth, a preferred implementation method is shown in Figure 5 The hole wall of the first through hole 12 has a first curved surface 14, the abutting section 32 has a protrusion 321, the outer surface of the protrusion 321 in contact with the hole wall of the first through hole 12 is a spherical surface, and the side of the protrusion 321 away from the threaded section 31 is a plane. In a specific setting, the abutting section 32 can be hemispherical, and the hemispherical shape can be a standard 1 / 2 sphere.
[0099] The above-mentioned installation unit 100, by limiting the shapes of the relative surfaces of the first through hole 12 and the abutment section 32 of the angle adjustment member 30 to be mutually matched curved surfaces, the rotation resistance of the angle adjustment member 30 in contact with the first curved surface 14 is small when the angle adjustment member 30 is screwed in and out, thereby facilitating the rotation of the angle adjustment member 30 and making the angle adjustment process smoother. In some embodiments, graphite powder or lubricating oil can also be applied to the outer surface of the abutment section 32 and the inner surface of the first through hole 12, so that the rotation resistance between the abutment section 32 and the inner surface of the first through hole 12 is smaller, making the angle adjustment process smoother.
[0100] By limiting the specific structure of the abutment section 32, the abutment section 32 can roll in the arc surface, so as to achieve smooth angle adjustment through a simple structure. In a specific setting, the angle adjustment member 30 can be a hemispherical head screw, and the hemispherical head is divided into a hemispherical protrusion integrally formed with the screw part, and at the same time, it is convenient to form an adjustment space 60 between the plane of the protrusion 321 and the limiter 50. In some embodiments, the first through hole 12 can be the first curved surface 14 as a whole, or a part of the first through hole 12 can be the first curved surface 14, and the other part can be other structural forms, and the two can be smoothly transitioned.
[0101] There are many structures of the angle adjustment member 30. In a preferred embodiment, the angle adjustment member 30 further includes a wrenching section 33. The wrenching section 33, the abutting section 32 and the threaded section 31 are coaxially arranged, and the wrenching section 33 is located on the side of the abutting section 32 away from the threaded section 31 and is spaced from the stop member 50. The above-mentioned installation unit 100, by providing the wrenching section 33, allows the operator to rotate the angle adjustment member 30 more conveniently by only wrenching the wrenching section 33, thereby facilitating the position of the housing 20 and the lens 200 installed on the housing 20 relative to the bracket 10 and the car.
[0102] In order to expand the swing range of the housing 20, a preferred embodiment is shown in FIG. Figure 6 , the angle θ of the shell 20 rotating around the rotation axis 11 is ±3°. In a specific setting, when the angle θ of the shell 20 rotating around the rotation axis 11 is 3°, the angle of the shell 20 swinging upward is 3°, and when the angle θ of the shell 20 rotating around the rotation axis 11 is -3°, the angle of the shell 20 swinging downward is 3°. The above-mentioned installation unit 100 limits the rotation angle range of the shell 20 so that the angle θ of the shell 20 swinging up and down is ±3°, so as to ensure the up and down swing amplitude of the shell 20 relative to the bracket 10. In a specific setting, the angle θ of the shell 20 rotating around the rotation axis 11 can be -3°, -2°, -1°, 1°, 2°, 3°, etc.
[0103] In order to facilitate the installation of the elastic member 40, a preferred embodiment is shown in FIG. Figure 5 The housing 20 and the bracket 10 have an accommodating space 70 formed on the opposite end faces. The elastic member 40 is sleeved on the angle adjusting member 30, and a portion of the elastic member 40 is accommodated in the accommodating space 70. In a specific configuration, the housing 20 has a first groove 23 opened on the end face facing the bracket 10, and the bracket 10 has a second groove 15 opened on the end face facing the housing 20. The first groove 23 and the second groove 15 cooperate to form the accommodating space 70. The ends of the elastic member 40 can be fixed to the bottoms of the first groove 23 and the second groove 15 by means of snap connection, concave-convex matching, adhesive bonding, etc.
[0104] The above-mentioned installation unit 100 limits the setting position of the elastic member 40, and the elastic member 40 is sleeved on the angle adjustment member 30 to facilitate the installation of the elastic member 40, and limits the elastic member 40 to be fixed in the accommodating space 70 to prevent the elastic member 40 from detaching from between the shell 20 and the bracket 10, thereby ensuring the stability of the elastic member 40 during the entire working process.
[0105] In order to facilitate the rotatable installation of the housing 20 on the bracket 10, a preferred embodiment is shown in FIG. Figure 2 and Figure 3The mounting unit 100 also includes two pins 80, wherein: the shell 20 includes a shell body 24, the shell body 24 includes a front shell 241 and a rear shell 242, the front shell 241 and the rear shell 242 can be detachably connected as a whole with the mounting hole 245 of the front shell 241 through a first screw 91 that passes through the rear shell 242. Of course, the detachable connection method of the front shell 241 and the rear shell 242 is not limited to this, and can also be a snap-on connection, a concave-convex fit, or the like. The rear shell 242 also includes two first plates 26 and a second plate 27. The two first plates 26 protrude from the left and right sides of the rear shell 242 along the extension direction of the rotation axis 11, and the first plates 26 are perpendicular to the rotation axis 11. The second plate 27 protrudes from the side of the rear shell 242 away from the front shell 241. The two first plates 26 are correspondingly provided with third through holes 28. The bracket 10 is respectively provided with fourth through holes 16 corresponding to the third through holes 28 on the left and right sides extending along the rotation axis 11. In the specific setting, the two fourth through holes 16 are symmetrically arranged, and the axes of the two fourth through holes 16 are located on the same straight line. At least one fifth through hole 243 is provided on the front shell 241. The number of the fifth through holes 243 can be one, two, three or more than three. The fifth through hole 243 forms the mounting position 22, and the angle adjustment hole 21 is provided on the second plate 27.
[0106] The pin 80 is disposed in the third through hole 28 and the fourth through hole 16, and the pin 80 can rotate relative to the third through hole 28 and the fourth through hole 16, thereby driving the housing 20 to rotate around the rotation axis 11, and the center of the two pins 80 is the axis of the rotation axis 11. Of course, the structural member used to realize the rotation in the third through hole 28 and the fourth through hole 16 is not limited to the pin 80, and can also be other structures that can meet the requirements.
[0107] When the angle adjustment member 30 is rotated by the above-mentioned mounting unit 100, the shell 20 has a tendency to move under the action of the threaded connection between the angle adjustment hole 21 and the angle adjustment member 30, and the shell 20 rotates relative to the bracket 10 with the pin shaft 80 as the rotation axis 11 to realize the swing of the shell 20 relative to the bracket 10. Therefore, by limiting the structure of the shell 20 and the bracket 10 and by setting the pin shaft 80, the shell 20 and the bracket 10 can be rotatably connected.
[0108] In order to facilitate the functional control of the lens 200, specifically, please refer to Figure 3The mounting unit 100 further includes a circuit board 92 and a functional component 93. The circuit board 92 can be fixed between the front shell 241 and the rear shell 242 by a second screw 94. Of course, the detachable connection method of the front shell 241 and the rear shell 242 is not limited thereto, and can also be a snap connection, a concave-convex fit, etc. The functional component 93 is installed on the circuit board 92 by snap connection, welding, a concave-convex fit, etc., and the functional component 93 is electrically connected to the circuit board 92 by means of wires, contacts, pads, etc. The functional component 93 is electrically connected to the circuit board 92 and the lens 200 by means of wires, contacts, etc. In a specific setting, the functional component 93 can be a functional component such as a photosensitive chip, a serializer, a power management integrated circuit, etc. The circuit board 92 is fixed to the stud 244 of the front shell 241 by a second screw 94.
[0109] In the above-mentioned mounting unit 100, the functional component 93 controls the functional operation of the lens 200 through the circuit board 92. By expanding the number of the functional components 93, more functional components are integrated on the circuit board 92 to enrich the functions of the lens 200. By arranging the functional components 93 on the circuit board 92 and arranging the circuit board 92 between the front shell 241 and the rear shell 242, the mounting unit 100 can be pre-assembled so that the mounting unit 100 can meet the functional control of the lens 200. In the specific setting, in order to facilitate the electrical connection between the lens 200 and the car, a plurality of connectors 95 are also provided on the mounting unit 100, and these connectors 95 are used to connect with the car.
[0110] For easy external connection to the car, a preferred implementation is shown in Figure 3 At least one ear plate 17 protrudes from the upper part of the bracket 10. The number of the ear plates 17 can be one, two, three or more than three. The multiple ear plates 17 are evenly distributed above the bracket 10. The ear plate 17 is provided with a connection hole 18. The ear plate 17 is externally connected to the car by screws penetrating the connection hole 18. Of course, the connection method between the ear plate 17 and the car is not limited to this, and can also be other methods that can meet the requirements, such as adhesive bonding or concave-convex matching.
[0111] The mounting unit 100 is provided with the ear plate 17 and the connection hole 18, and can fix the bracket 10 and the car only by the locking action of the screws, so as to fix the bracket 10 to the car.
[0112] Also, see Figure 7The second embodiment of the present application provides a mounting unit 300. The mounting unit 300 provided in the second embodiment is substantially similar in structure to the mounting unit 100 provided in the first embodiment. The difference is that in the second embodiment, the angle adjustment member 302 of the mounting unit 300 includes a wrench section 332, an abutment section 322 and a clamping section 34 connected in sequence. The clamping section 34 is provided with a clamping protrusion 341. The clamping protrusion 341 is annular and arc-shaped. A plurality of clamping grooves 211 are provided on the inner surface of the angle adjustment hole 210 along the thickness direction. The clamping grooves 211 are annular and matched with the clamping protrusions 341.
[0113] The above-mentioned installation unit 300, by making the snap-in protrusion 341 on the angle adjustment member 302 snap into different snap-in grooves 211, makes the shell 201 tend to move away from the bracket 101 or closer to the bracket 101 under the action of the angle adjustment member 302, the angle adjustment hole 210 and the elastic member 401, and rotates relative to the bracket 101, so as to realize the shell 201 swinging downward or upward at a certain angle relative to the bracket 101.
[0114] In other embodiments, the engaging protrusion 341 may also be elastically disposed on the engaging section 34 , so that the engaging protrusion 341 can be easily disengaged from one engaging groove 211 and engaged in another engaging groove 211 .
[0115] In other embodiments, two, three or more than three clamping protrusions 341 may be provided on the clamping section 34 .
[0116] In other embodiments, a plurality of engaging grooves 211 may be provided on the outer surface of the angle adjustment member 302 , and an engaging protrusion 341 may be provided on the inner surface of the angle adjustment hole 210 .
[0117] Also, see Figure 8 The third embodiment of the present application provides a camera module 1, which includes at least one lens 200. The camera module 1 also includes the mounting unit 100 of the first embodiment or the mounting unit 300 of the second embodiment. The third embodiment is described by taking the mounting unit 100 of the first embodiment as an example. The lens 200 is respectively arranged on the mounting position 22 of the mounting unit 100 by means of threaded connection, snap connection, concave-convex matching, etc. The mounting position 22 is arranged on the side of the shell 20 away from the bracket 10.
[0118] In the above-mentioned camera module 1, since the angle adjustment member 30 is screwed into the mounting unit 100 in the direction from the bracket 10 toward the shell 20, the shell 20 has a tendency to move toward the bracket 10 under the action of the threaded connection between the angle adjustment hole 21 and the angle adjustment member 30, and will rotate around the rotating shaft 11 to achieve the shell 20 swinging upward at a certain angle relative to the bracket 10. The angle adjustment member 30 is unscrewed in the direction where the bracket 10 is away from the shell 20. Since the abutment section 32 abuts against the bracket 10, the shell 20 has a tendency to move in the direction away from the bracket 10 under the threaded connection between the angle adjustment hole 21 and the threaded section 31, and will rotate around the rotation axis 11 to achieve a downward swing of the shell 20 relative to the bracket 10 at a certain angle. At the same time, since one end of the limiting member 50 inserted into the first through hole 12 is located on the side of the abutment section 32 away from the threaded section 31, when the angle adjustment member 30 is unscrewed, the angle adjustment member 30 is blocked in the first through hole 12 by the stopping action of the limiting member 50, thereby preventing the angle adjustment member 30 from disengaging from the first through hole 12 and sliding down along the unscrewing direction. The elastic member 40 supports the housing 20 and provides a tendency to move the housing 20 away from the bracket 10 when the housing 20 is impacted by an external force, so that the housing 20 and the bracket 10 maintain a relatively fixed angle, avoiding the housing 20 from rotating relative to the bracket 10 when subjected to an external force, playing a role in buffering vibrations and ensuring the stability between the housing 20 and the bracket 10. Therefore, the camera module 1 with the mounting unit 100 can realize the up and down swinging of the lens 200, which is convenient for the calibration and field of view adjustment of the lens 200, and the angle of the lens 200 will not change even when the car drives on a bumpy road or a collision generates acceleration, and the stability is good.
[0119] In addition, the fourth embodiment of the present application also provides a car (not shown), the car includes a body and the camera module 1 of the third embodiment, the camera module 1 is installed on the body. In the above car, since the camera module 1 can realize the up and down swing of the lens 200, it is convenient for the calibration and field of view adjustment of the lens 200, and the angle of the lens 200 will not change even when the car drives on a pothole road or a collision occurs to generate acceleration, and the stability is good. Therefore, the image acquisition effect of the car with the camera module 1 is better, and the driving experience and safety are better.
