Description

Technical Field

[0001] The present invention belongs to the technical field of measurement, and particularly relates to a miniaturized vehicle-mounted camera and its welding tooling. Background Art

[0002] With the rapid development of the automotive industry and the rapid rise of the intelligent driving technology of new energy vehicles, as the eyes of intelligent driving, the hardware technology of vehicle-mounted cameras has become increasingly mature, and its structural configuration mode has become increasingly fixed. The disadvantages of the existing structure include: (1) Vehicle-mounted cameras are generally cube-shaped structures, and they do not have an advantage in the installation space of the whole vehicle. The camera lens is a rotating body structure, which has little advantage in the installation of the whole vehicle, especially in terms of space utilization. For example, in the installation of side cameras and surround-view cameras in the outer rearview mirror, the camera body is relatively large, which has a certain impact on the installation reliability and styling. (2) In the existing vehicle-mounted camera solutions, generally, the image sensor board (sensor board) is locked to the front shell by screws, the power board is locked to the rear shell by screws, and then the front and rear shells are locked by screws. After the sealing ring between the front and rear shells is compressed for sealing, and then the lens and the front shell are subjected to dotting AA (active alignment) and then UV curing connection. This not only involves more parts, but also the process is very complex, which affects the production beat of the camera, and there are also risks of locking failure and poor airtightness. The screw connection process is also not conducive to miniaturization. (3) Even if the screw connection is replaced by laser welding, the vehicle-mounted camera housing is generally mainly cube-shaped. During the laser welding process of the square front and rear shells, there are problems such as complex welding trajectories and degrees of freedom of movement of the welding head (welding equipment). Especially during the welding process of space curves, the kinematic modeling is relatively complex, the degrees of freedom of movement of the workpiece and the laser head are relatively many, and there are many servo mechanisms, and the welding stability is greatly tested.

[0003] Therefore, it is necessary to design a miniaturized vehicle-mounted camera and its welding tooling. Summary of the Invention

[0004] In view of the above-mentioned disadvantages of the prior art, the purpose of the present invention is to provide a miniaturized vehicle-mounted camera and its welding tooling, which replaces the screw connection with a welding connection method, and the housing has a cylindrical structure. During welding, the welding tooling drives the front shell and the rear shell to rotate to achieve welding, with stable welding, ensuring the welding efficiency and quality.

[0005] To achieve the above-mentioned purpose and other related purposes, the present invention provides a miniaturized vehicle-mounted camera, including:

[0006] A housing, the housing is cylindrical and includes a front shell and a rear shell connected by welding;

[0007] A lens module, the lens module is adhered to one end of the front shell away from the rear shell;

[0008] A PCB board, and the PCB board is fixedly installed in the housing;

[0009] Wherein, on one side of the front housing facing away from the lens module, there is a pressing boss, and on one side of the rear housing facing the lens module, there is a counterbore. A part of the PCB board is located between the counterbore and the pressing boss to achieve pressing and fixing.

[0010] In a preferred embodiment of the present invention, the PCB board includes:

[0011] A body;

[0012] A plurality of lugs, and the plurality of lugs are arranged at intervals along the circumference of the body. The lugs are located between the counterbore and the pressing boss.

[0013] In a preferred embodiment of the present invention, at least two of the counterbores are provided with positioning posts, and the pressing boss and the lugs are provided with positioning holes, or at least two positioning posts are provided on the pressing boss, and the counterbore and the lugs are provided with positioning holes; the positioning holes correspond to the positioning posts one by one.

[0014] In a preferred embodiment of the present invention, both the front housing and the rear housing are die-cast or cold-extruded parts made of aluminum alloy.

[0015] In a preferred embodiment of the present invention, on one side of the front housing for installing the lens module, there is an end face boss, and around the outer shell of the lens module, there is an installation boss, and the installation boss and the end face boss are bonded by a UV glue layer.

[0016] In a preferred embodiment of the present invention, at one end of the rear housing away from the front housing, there is a connector, and the axis of the connector is parallel to the axis of the housing.

[0017] In a preferred embodiment of the present invention, on one side of the PCB board, there is an image sensor, and on the other side, there are board-end terminals. The board-end terminals are cooperatively connected with the connector, and the image sensor is aligned with the optical elements of the lens module.

[0018] To achieve the purpose and other purposes of the present invention, the present invention provides a welding tooling for a camera, which is used for clamping the above-mentioned miniaturized vehicle-mounted camera, and includes:

[0019] A front housing welding sleeve, and the front housing welding sleeve is cooperatively sleeved on the front housing;

[0020] A rear housing welding sleeve, and the rear housing welding sleeve is cooperatively sleeved on the rear housing;

[0021] Wherein, the end faces of the front shell and the rear shell are in contact, and the front shell and the rear shell are located on the same axis. The front shell welding sleeve and the rear shell welding sleeve drive the front shell and the rear shell to rotate synchronously around their axes respectively.

[0022] In a preferred embodiment of the present invention, a positioning port is provided at one end of the front shell away from the rear shell, and a positioning block is provided on the inner side wall of the front shell welding sleeve. The positioning port and the positioning block cooperate to position the front shell.

[0023] In a preferred embodiment of the present invention, a positioning pin is provided at one end of the rear shell away from the front shell, a positioning plate is provided in the rear shell welding sleeve, and a pin hole is provided on the positioning plate. The positioning pin and the pin hole cooperate to position the rear shell.

[0024] The beneficial technical effects of the present invention at least include:

[0025] (1) A miniaturized vehicle-mounted camera of the present invention includes a housing, a PCB board, and a lens module. The front shell and the rear shell are welded to form a cylindrical housing. The PCB board is clamped and installed inside the housing by the pressing boss of the front shell and the counterbore of the rear shell. The lens module is bonded to one end of the front shell away from the rear shell. The screwless connection and installation of the entire camera are realized. At the same time, due to the setting of the PCB board (the PCB board integrates an image sensor, a power supply, and board-end terminals, and the board-end terminals cooperate with a connector for connection), the components of the camera are greatly reduced, making the vehicle-mounted camera of the present invention miniaturized. The miniaturized camera occupies less space in the vehicle installation space, realizing the miniaturization of the vehicle-mounted camera. For example, for a camera arranged in the external rearview mirror of a vehicle, at the same spatial position, the miniaturized vehicle-mounted camera of the present invention significantly occupies less space and has more advantages for the overall vehicle layout. At the same time, the welding connection process design of the front shell and the rear shell of the camera of the present invention and the clamping and installation method of the PCB board optimize the assembly process of the camera, making the connection more stable while improving the efficiency.

[0026] (2) A welding tooling for a miniaturized vehicle-mounted camera of the present invention includes a front shell welding sleeve and a rear shell welding sleeve. The front shell welding sleeve is sleeved on the front shell in a matching manner, and the rear shell welding sleeve is sleeved on the rear shell in a matching manner. Since the housing of the camera is cylindrical, and the welding tooling is configured to match the structure of the housing, during the welding process, only the workpiece needs to be positioned and installed, and the workpiece rotates with the welding tooling. The laser head always remains stationary, eliminating the need for a multi-axis and multi-degree-of-freedom laser device. There is no need to worry about the welding instability caused by the multi-axis movement / rotation of the laser device, greatly simplifying the welding programming and process equipment, reducing the input of production costs, optimizing the product manufacturing beat, and improving the welding stability and reliability.

Detailed implementation manners

[0047] The following uses specific specific examples to illustrate the implementation manners of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0048] It should be noted that the illustrations provided in this embodiment only schematically illustrate the basic concept of the present invention. Therefore, only the components related to the present invention are shown in the drawings, rather than being drawn according to the number, shape, and size of the components during actual implementation. The types, quantities, and proportions of the components during actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0049] Please refer to Figure 1 and Figure 2As shown in the figure, to achieve the above and other related purposes, the present invention provides a miniaturized vehicle-mounted camera, which includes a housing, a lens module 3 and a PCB board 2. The housing is cylindrical and includes a front shell 11 and a rear shell 12 connected by welding. The lens module 3 is bonded to one side of the front shell 11 away from the rear shell 12. The PCB board 2 is fixedly installed inside the housing. Among them, a pressing boss is provided on one side of the front shell 11 facing away from the lens module 3, a counterbore is provided on one side of the rear shell 12 facing the lens module 3, and a part of the PCB board 2 is located between the counterbore and the pressing boss to achieve pressing and fixing.

[0050] It should be noted that the front shell 11 and the rear shell 12 are welded to form the housing. The pressing boss and the counterbore cooperate to clamp and install the PCB board 2 inside the housing, and the lens module 3 is bonded to one end of the front shell 11 away from the rear shell 12. Therefore, the vehicle-mounted camera of the present invention realizes the "zero" screw locking assembly process. It not only reduces the components of the camera, but also optimizes the connection and assembly process steps. The housing is of a cylindrical structure, breaking the cubic structure of the vehicle-mounted camera. Its rotating body structure not only corresponds to the lens structure, but also is convenient for vehicle installation and saves layout space. Moreover, it greatly simplifies the welding process of the camera. Specifically, in the traditional cubic camera structure during laser welding, the welding head moves in a multi-return curve in space. Since the camera of the present invention is cylindrical, during welding, the position of the welding head can be fixed, and the welding fixture drives the camera to rotate, and welding can be achieved. Its programming is simple, the welding is stable, and the welding efficiency and quality are improved.

[0051] In a preferred embodiment of the present invention, please refer to Figure 3 and Figure 4 As shown, the PCB board 2 includes a body and a plurality of lugs 21. The plurality of lugs 21 are arranged at intervals along the circumference of the body, and the lugs 21 are located between the counterbore and the pressing boss.

[0052] In a preferred embodiment of the present invention, at least two positioning posts 122 are provided on the counterbore, and positioning holes are provided on the pressing boss and the lugs 21. The positioning holes correspond to the positioning posts 122 one by one. The positioning posts 122 pass through the positioning holes on the pressing boss and the lugs 21 in sequence.

[0053] In a preferred embodiment of the present invention, at least two positioning posts 122 are provided on the pressing boss, and positioning holes are provided on the counterbore and the lugs. The positioning holes correspond to the positioning posts 122 one by one. The positioning posts 122 pass through the positioning holes on the counterbore and the lugs 21 in sequence.

[0054] Furthermore, the pressing boss includes a convex ring 112 and an ear plate 113, and the ear plate 113 protrudes from the outer circumference of the convex ring 112; the counterbore includes a plurality of ear-shaped counterbore grooves 121 protruding from the inner wall of the rear shell 12, and the ear plate 113 and the counterbore grooves 121 cooperate to clamp and install the lugs 21.

[0055] It should be noted that both the front shell 11 and the rear shell 12 are cylindrical. Through the design of the pressing boss and the counterbore 121, the PCB board 2 is clamped inside the housing, preventing the PCB board 2 from shifting or loosening under vibration or impact. This installation method can effectively improve the reliability and service life of the device. The cooperation between the ear plate 113 and the counterbore 121 provides a simple and efficient clamping method, reducing the complexity during the assembly process. The design of the lug 21 enables the fixed installation of the PCB board 2 within a limited space. Therefore, the above method for installing the PCB board 2 avoids additional support structures or brackets, thus effectively saving internal space and facilitating the miniaturization design of the device.

[0056] In a preferred embodiment of the present invention, both the front shell 11 and the rear shell 12 are die-cast or cold-extruded parts made of aluminum alloy.

[0057] It should be noted that aluminum alloy has a lower density compared to other metals (such as steel), which can effectively reduce the overall weight of the product while still having relatively high strength. Aluminum alloy has good thermal conductivity and can effectively dissipate heat, which is particularly beneficial for electronic devices that require heat dissipation. A natural oxide film can form on the surface of aluminum alloy, making it have good corrosion resistance in most environments and extending the service life of the components. Aluminum alloy is easy to process. Processes such as die-casting and cold extrusion can achieve complex structural designs while ensuring high dimensional accuracy. Among them, die-casting and cold extrusion processes can achieve the forming of complex shapes, reducing subsequent processing requirements and improving production efficiency.

[0058] In a preferred embodiment of the present invention, on the side of the front shell 11 where the lens module 3 is installed, there is an end face boss 111. An installation boss 31 is provided around the outer shell of the lens module 3, and the installation boss 31 and the end face boss 111 are bonded through a UV glue layer 32.

[0059] It should be noted that the bonding of the UV glue layer 32 can effectively enhance the connection strength between the front shell 11 and the lens module 3, avoiding loosening or damage caused by vibration or external forces during use and improving the overall reliability of the product. The design of the end face boss 111 may contribute to the precise positioning of the lens module 3, thus making the alignment of the optical elements and the image sensor 22 of the lens module 3 more accurate and improving the imaging quality.

[0060] In a preferred embodiment of the present invention, please refer to Figure 5 and Figure 6 As shown, at one end of the rear shell 12 away from the front shell 11, there is a connector 4, and the axial direction of the connector 4 is parallel to the axial direction of the housing.

[0061] It should be noted that the connector 4 is a FAKRA interface, which is used to connect various wireless communication devices in the vehicle, such as GPS, in-vehicle phone, in-vehicle wireless network, etc.

[0062] In a preferred embodiment of the present invention, please refer to Figure 7 and Figure 8 As shown, the PCB board 2 is installed inside the housing. An image sensor 22 is provided on one side of the PCB board 2, and a board terminal 23 is provided on the other side. The board terminal 23 is cooperatively connected with the connector 4, and the optical element of the lens module 3 is aligned with the image sensor 22.

[0063] It should be noted that the PCB board 2 integrates a traditional sensor board and a power board on one PCB board 2. The outer shape of the PCB board 2 is in a shape similar to the inner contour of the front and rear shells 12 for installation and space saving.

[0064] Please refer to Figures 9 - 11 As shown, when the front shell 11 and the rear shell 12 are welded and connected, the height of the pressing boss on the front shell 11, the thickness of the PCB board 2, and the depth of the sinking groove 121 on the rear shell 12 need to meet the following conditions: the sum of the height of the pressing boss and the thickness of the PCB board 2 is slightly less than the depth of the sinking groove 121, as shown in Figure 11 As shown, where the height of the pressing boss is represented by B, the thickness of the PCB board 2 is represented by C, and the depth of the sinking groove 121 is represented by A. At this time, when the connection ends of the front shell 11 and the rear shell 12 are fitted, there is a gap between them, so that the welding material can be fully filled into the connection area during welding to ensure the firmness of the welding. Further, grooves are respectively provided on the outer circumferences of the connection ends of the front shell 11 and the rear shell 12 to accommodate the solder during welding.

[0065] Please refer to Figures 12 - 14 As shown, to achieve the purpose and other purposes of the present invention, the present invention provides a welding tool for a camera, which is used to clamp the above-mentioned miniaturized vehicle-mounted camera, and includes a front shell welding sleeve 10 and a rear shell welding sleeve 20. The front shell welding sleeve 10 is cooperatively sleeved on the front shell 11; the rear shell welding sleeve 20 is cooperatively sleeved on the rear shell 12; wherein, the end faces of the front shell 11 and the rear shell 12 are attached, so that the front shell 11 and the rear shell 12 are located on the same axis, and the front shell welding sleeve 10 and the rear shell welding sleeve 20 respectively drive the front shell 11 and the rear shell 12 to rotate synchronously around their axes.

[0066] It should be noted that after the tooling and the semi-finished camera are assembled in place, that is, the front shell welding sleeve 10 is fitted over the front shell 11, and the rear shell welding sleeve 20 is fitted over the rear shell 12. Place it under the hydraulic and horizontal rotating spindle, apply an appropriate pressure through the hydraulic device, and the direction of the pressure is parallel to the axial direction of the shell. At this time, the connecting ends of the front shell 11 and the rear shell 12 are in contact with each other with a gap. The front shell 11 and the rear shell 12 make a rotational movement at a certain rotational speed driven by the rotating spindle. The laser emission device adjusts appropriate welding parameters, and a laser beam is emitted through the laser head of the laser emission device and applied to the welding area of the front shell 11 and the rear shell 12. One rotation is completed to finish the complete welding of the camera (if friction stir welding is used, the laser head can be replaced with a friction tool head). The advantage of this camera welding is that only the workpiece needs to make a rotary motion with the welding carrier, and the laser head always remains stationary. There is no need for a multi-axis and multi-degree-of-freedom laser device, and there is no need to worry about the welding instability caused by the multi-axis movement / rotation of the laser device. The feasibility and economy are very high.

[0067] Please refer to Figure 15 As shown, for the semi-finished camera after welding, a UV glue layer 32 is coated between the end face boss 111 of the front shell 11 and the mounting boss 31 of the lens module 3. The position of the lens module 3 and the semi-finished product is adjusted through the AA adjustment device, mainly aligning the optical elements of the lens module 3 and the image sensor 22, and adjusting the relative position and angle of the imaging surfaces of the optical elements and the image sensor 22. After the adjustment is completed, it is cured by UV light and baked to finally obtain the finished product of the miniaturized vehicle-mounted camera.

[0068] In a preferred embodiment of the present invention, a positioning port 114 is opened at one end of the front shell 11 away from the rear shell 12, and a positioning block 101 is provided on the inner side wall of the front shell welding sleeve 10. The positioning port 114 and the positioning block 101 cooperate to position the front shell 11. A positioning pin 123 is provided at one end of the rear shell 12 away from the front shell 11, a positioning plate 201 is provided in the rear shell welding sleeve 20, and a pin hole is opened on the positioning plate 201. The positioning pin 123 and the pin hole cooperate to position the rear shell 12.

[0069] It should be noted that in the design of modern automobiles, they are becoming more and more compact, and the space requirements for various sensors and devices are increasing. Miniaturized vehicle-mounted cameras can be more easily integrated into various parts of the vehicle body, such as the rearview mirror, the front of the vehicle, the rear of the vehicle, etc. The small camera is more convenient to install and can be placed in a more flexible position, thus providing a better field of view and monitoring angle. At the same time, due to its small size, it is not easy to interfere with other devices and components during installation. The small camera can better monitor blind spots and the driving environment, help the driver improve alertness, reduce the risk of accidents, and thus improve driving safety.

[0070] The square vehicle-mounted cameras in the prior art, such as Figures 16 - 17As shown, the image sensor board 01 is fastened to the square front shell by screws, and the power board 02 is fastened to the square rear shell by screws. Then, the square front shell 04 and the square rear shell 05 are fastened by screws. The sealing ring 03 between the square front shell 04 and the square rear shell 05 is compressed for sealing. Then, after dispensing AA (active alignment) between the lens module 3 and the square front shell, UV curing connection is carried out. It can be seen that the in-vehicle camera in the prior art not only involves many parts, but also has a very complex process, which affects the production rhythm of the camera. There are also risks of fastening failure and poor airtightness. The screw connection process, the square front shell 04, and the square rear shell 05 are not conducive to the miniaturization of the in-vehicle camera.

[0071] See Figure 18 As shown, the number of components forming the above camera is reduced, and the cylindrical shell makes the overall size smaller, occupying less installation space in the whole vehicle, achieving miniaturization. For example, for the camera arranged in the external rearview mirror of the vehicle, at the same spatial position, the miniaturized in-vehicle camera of the present invention significantly occupies less space and has more advantages for the overall vehicle layout.

[0072] In summary, (1) A miniaturized in-vehicle camera of the present invention includes a shell, a PCB board 2, and a lens module 3. The front shell 11 and the rear shell 12 are welded to form a cylindrical shell. The PCB board 2 is clamped and installed inside the shell by the pressing boss of the front shell and the counterbore of the rear shell. The lens module 3 is bonded to one end of the front shell 11 away from the rear shell 12. The screwless connection and installation of the entire camera are realized. At the same time, due to the setting of the PCB board (the PCB board 2 integrates an image sensor 22, a power supply, and board-end terminals 23, and the board-end terminals 23 are connected to the connector 4), the number of components forming the camera is greatly reduced, making the in-vehicle camera of the present invention achieve miniaturization.

[0073] At the same time, the welding process of the front shell 11 and the rear shell 12 and the clamping and installation method of the PCB board 2 optimize the assembly process of the camera, making the connection more stable while improving the efficiency.

[0074] (2) A welding tooling for a miniaturized in-vehicle camera of the present invention includes a front shell welding sleeve 10 and a rear shell welding sleeve 20. The front shell welding sleeve 10 is fitted and sleeved on the front shell 11; the rear shell welding sleeve 20 is fitted and sleeved on the rear shell 12. Since the shell of the camera is cylindrical, only the workpiece needs to rotate with the welding tooling, and the laser head always remains stationary. There is no need for a multi-axis and multi-degree-of-freedom laser device, and there is no need to worry about the welding instability caused by the multi-axis movement / rotation of the laser device. The welding programming and process equipment are greatly simplified, reducing the input of production costs, optimizing the product manufacturing rhythm, and improving the welding stability and reliability.
