Description

Technical Field

[0001] The present application relates to the field of cameras, and in particular to a heating camera structure. Background Art

[0002] With the rapid development of intelligent driving, more and more cars are integrated with intelligent driving assistance systems. Car cameras are an important part of intelligent driving assistance systems. As the complexity of the functions to be realized by cameras continues to increase, cameras have higher and higher requirements for the environment in which they are located. In rainy and snowy weather or when the temperature is low, water mist on the camera will seriously affect the imaging, limiting the functions of the intelligent driving assistance system and affecting driving safety. Therefore, car cameras need to support heating functions to eliminate water mist.

[0003] In the prior art, a heating plate is usually arranged inside the lens module, and a wire is extended outward to connect with the circuit board, so as to control the heating plate for heating. This structure requires manual pre-processing when assembling the camera, and the wire is glued and fixed on the shell to avoid affecting the AA process (Active Alignment equipment automatic calibration). After the lens module and the circuit board are automatically calibrated by the equipment, the wire and the circuit board need to be manually welded. The whole assembly process is inefficient and the automation of the assembly process cannot be realized through existing equipment. Utility Model Content

[0004] In response to the above-mentioned problems, the purpose of this application is to provide a heating camera structure, reduce the complexity of the assembly process, optimize manpower, automate the camera assembly process through existing equipment, and improve assembly production efficiency.

[0005] The purpose of this application is achieved through the following technical solutions:

[0006] A heating camera structure includes a front shell component and a rear shell component, the front shell component and the rear shell component can be connected to form a cavity, an adapter plate and a circuit board are arranged in the cavity, the front shell component includes a heating body, the heating body is provided with a connecting part, the connecting part extends toward the cavity and is electrically connected to the adapter plate, the adapter plate is provided with a first conductive part, the circuit board is provided with a second conductive part, the first conductive part is in contact with the second conductive part and is electrically connected.

[0007] The connection part of the heating body and the adapter plate are pre-electrically connected through the operation of automated equipment. No manual intervention is required during the automatic calibration of the equipment, and the equipment can directly perform alignment operations. The first conductive part is designed on the adapter plate, and the second conductive part is designed on the circuit board. After the automatic calibration of the front shell component and the circuit board is completed, the first conductive part and the second conductive part are in direct contact to achieve electrical connection between the two. No manual welding is required, and the stability of the connection between the two can be guaranteed. By optimizing the design of the connection part of the heating body, the adapter plate and the second conductive part of the circuit board, the traditional structural design of connecting the heating body and the circuit board through a wire is replaced, and manual operations in the process flow are eliminated. The automation of the assembly process is realized without the need to modify the equipment or change the assembly process, and the efficiency of assembly production is improved.

[0008] Furthermore, the front shell assembly is provided with a channel, and the connecting portion passes through the channel and extends from the bottom of the front shell assembly.

[0009] A channel is provided inside the front shell assembly, and the connection part of the heater is routed and fixed close to the inner wall of the channel, so as to avoid shaking of the connection part and cause abnormal connection between the connection part and other components in some special scenarios.

The connecting portion passes through the hollow portion, and the bent portion is in contact with the electrical connection point for electrical connection.

[0011] After the connecting part of the heating body passes through the hollow part of the front shell assembly and the adapter plate, it is bent at the end to form a bent part. The bent part and the electrical connection point on the adapter plate are automatically welded by automated equipment, thereby avoiding the influence of the connecting part on the alignment process during the automatic calibration of the equipment.

The first conductive contact and the second conductive contact are respectively in contact with the first conductive medium and the second conductive medium to achieve circuit conduction. At the same time, the use of this extrusion contact type electrical connection eliminates the manual welding process, which not only improves assembly efficiency, but also saves manpower investment.

[0014] Further, the surface areas of the first conductive contact and the second conductive contact are larger than the surface areas of the first conductive medium and the second conductive medium.

[0015] It is ensured that after the device is automatically calibrated and the position is shifted, the first conductive contact and the second conductive contact can still be in good contact with the first conductive medium and the second conductive medium, thereby ensuring the stability of the electrical connection.

[0017] On the adapter board, the first conductive contact and the second conductive contact are respectively located at opposite positions on both sides of the electrical connection point, ensuring the stability of the contact connection with the first conductive medium and the second conductive medium, as well as the accuracy during the automatic calibration and alignment of the device.

[0018] Furthermore, the bottom of the front shell assembly is provided with a plurality of connecting bosses, the adapter plate is provided with a plurality of through holes, and the connecting bosses correspond to the through holes one by one and pass through the through holes.

[0019] A connecting boss is arranged at the bottom of the front shell component, which passes through the adapter plate and contacts the circuit board, so that a certain space is formed between the circuit board and the adapter plate to accommodate the electrical components on the circuit board.

[0020] Furthermore, the circuit board is provided with a plurality of UV adhesive media, and the connecting bosses are connected to the UV adhesive media in a one-to-one correspondence.

[0021] The connecting boss is in contact with the UV glue medium. After the automatic calibration of the equipment is completed, the UV glue medium is irradiated with a UV lamp to complete the initial curing, so that the circuit board is initially bonded to the front shell assembly, and then baked in an oven to complete the final curing, so that the circuit board and the front shell assembly are bonded and fixed together.

[0022] Furthermore, the front shell assembly includes a front shell, the rear shell assembly includes a rear shell, the bottom side wall of the front shell is an L-shaped step structure, and the L-shaped step structure is tightly matched with the inner wall of the rear shell.

[0023] After the assembly is completed, the front shell assembly is tightly fitted with the rear shell assembly through the L-shaped step structure at the bottom, and then connected through a laser welding process to complete the assembly of the entire camera.

[0024] Furthermore, the end surfaces of the front shell and the rear shell that contact each other are conductive surfaces.

[0025] The front shell and the rear shell are in conductive contact with each other, so when the camera module in the front shell assembly is interfered by static electricity, the static electricity can be released through conduction of the shell.

[0026] Compared with the prior art, the beneficial effects of this application are:

[0027] The connection part of the heating body and the adapter plate are pre-electrically connected through the operation of automated equipment. No manual intervention is required during the automatic calibration of the equipment, and the equipment can directly perform alignment operations.
