Description

Technical Field

[0001] The present application relates to the technical field of vehicle-mounted cameras, and in particular to a vehicle-mounted camera and a vehicle. Background Art

[0002] In order to improve the product performance of the camera, the requirements for the electromagnetic shielding of the camera are getting higher and higher. At present, there are mainly two electromagnetic shielding schemes: one is to assemble a mechanical shielding cover on the electronic components that need to be electromagnetically shielded; the other is to apply metal coating inside the shell of the camera. However, the above two electromagnetic shielding schemes have the following defects: First, the processing conditions of the mechanical shielding cover are relatively high. With the accumulation of the processing error and assembly error of the mechanical shielding cover itself, the shielding effect of the mechanical shielding cover is weakened to a certain extent. At the same time, the processing cost of the mechanical shielding cover is high, and the development cycle is long, which leads to increased shielding costs. In addition, the mechanical shielding cover has certain requirements for the assembly space. The internal structure space of some precision products is small, which makes the assembly of the mechanical shielding cover difficult, resulting in shielding failure; second, the metal coating has high requirements for the early cleaning process of the camera shell, which leads to increased shielding costs. Utility Model Content

[0003] In view of the above, it is necessary to provide a vehicle-mounted camera and a vehicle to improve the shielding effect and reduce the shielding cost.

[0004] The present application provides a vehicle-mounted camera, including:

[0005] a first shell;

[0012] The above-mentioned vehicle-mounted camera, by arranging a shielding film on the side of the circuit board away from the lens and making the shielding film attached to the circuit board and completely covering the first electronic component that needs electromagnetic shielding, the shielding film completely covers the first electronic component to achieve electromagnetic shielding for the first electronic component, thereby preventing the first electronic component from being affected by external electromagnetic influences or mutual influence with electromagnetic induction of other components, and also preventing the electromagnetic field generated by the first electronic component from affecting other high-precision electronic components, which is beneficial to improving the shielding effect; by limiting the shielding film to a thermoplastic film, the thermoplastic film can be completely attached to the circuit board and the first electronic component by hot air blowing, so that the assembly of the shielding film is not affected by parameters such as space, position, and distance, the operation method is simple, and it is beneficial to reduce the shielding cost.

[0014] The above-mentioned vehicle-mounted camera has avoidance holes on the shielding film. When the shielding film is assembled, the shielding film can avoid the second electronic component that does not need to be shielded through the avoidance holes. The shielding film only needs to cover the first electronic component that needs to be shielded as much as possible, thereby saving the cost of the shielding film and thus reducing the shielding cost.

[0019] In one of the embodiments, the thickness of the shielding film ranges from 0.035 mm to 1 mm.

[0020] The above-mentioned vehicle-mounted camera limits the thickness range of the shielding film. On the one hand, it enables the shielding film to tightly wrap the surface of the first electronic component. On the other hand, it improves the strength of the shielding film to avoid the shielding film from being torn when assembling the shielding film.

[0021] In one embodiment, the first shell and the second shell, and the lens and the first shell are connected by laser welding, threaded connection or glue connection.

[0022] The above-mentioned vehicle-mounted camera, by limiting the connection mode between the first shell and the second shell and between the lens and the first shell, is conducive to improving the connection stability of various structures in the vehicle-mounted camera. Among them, the laser welding connection mode can also improve the sealing performance between the first shell and the second shell and between the lens and the first shell, thereby improving the sealing performance of the vehicle-mounted camera.

[0023] In one embodiment, the ratio of the unfolded area of ​​the shielding film to the shielding area of ​​the circuit board is 1.2-1.5, and the shielding area of ​​the circuit board is the projection area of ​​the shielding film on the circuit board along the direction of the optical axis of the vehicle-mounted camera.

[0024] The above-mentioned vehicle-mounted camera limits the ratio of the unfolded area of ​​the shielding film to the shielding area of ​​the circuit board. On the one hand, the shielding film can completely cover the first electronic component. On the other hand, the cost of the shielding film is saved, thereby reducing the shielding cost.

[0025] In one embodiment, a positioning column and a positioning hole spaced apart from the positioning column are disposed on a side of the second shell facing away from the first shell.

[0026] The above-mentioned vehicle-mounted camera is provided with a positioning column on the second shell so as to realize precise connection between the vehicle-mounted camera and the external structure; and a positioning hole is provided on the second shell so as to enable a screw to pass through the positioning hole and connect with the circuit board and the first shell, so that the first shell, the circuit board and the second shell are fixedly connected.

[0027] In one embodiment, the first shell and the second shell are both integrally formed structures.

[0028] The above-mentioned vehicle-mounted camera improves the strength of the first shell and the second shell by limiting the first shell and the second shell to be an integrally formed structure, and at the same time improves the assembly efficiency of the vehicle-mounted camera.

[0029] An embodiment of the present application also provides a vehicle, comprising a vehicle body and a vehicle-mounted camera as described in any of the above technical solutions, wherein the vehicle-mounted camera is arranged on the vehicle body.

[0030] In the above-mentioned vehicle, the on-board camera sets a shielding film on the side of the circuit board away from the lens and makes the shielding film attached to the circuit board and completely covers the first electronic component that needs electromagnetic shielding. The shielding film completely covers the first electronic component to achieve electromagnetic shielding for the first electronic component, thereby preventing the first electronic component from being affected by external electromagnetic influences or mutual influence of electromagnetic induction with other components in the vehicle body, and also preventing the electromagnetic field generated by the first electronic component from affecting other high-precision electronic components in the vehicle body, which is beneficial to improving the shielding effect; by limiting the shielding film to a thermoplastic film, the thermoplastic film can be completely attached to the circuit board and the first electronic component by hot air blowing, so that the assembly of the shielding film is not affected by parameters such as space, position, and distance, and the operation method is simple, which is beneficial to reducing shielding costs.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0060] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0061] Please refer to Figures 1 to 4 The embodiment of the present application provides a vehicle-mounted camera 100 . The vehicle-mounted camera 100 includes a first housing 10 , a second housing 20 , a lens 30 , a circuit board 40 , a photosensitive chip 50 , a first electronic component 60 and a shielding film 70 .

[0062] The first housing 10 is connected to the second housing 20 and forms a receiving cavity 25, which is used to receive components such as the circuit board 40, the photosensitive chip 50, the first electronic component 60, and the shielding film 70. The first housing 10 and the second housing 20 can both be an integrally formed structure. In this way, by limiting the first housing 10 and the second housing 20 to be an integrally formed structure, the strength of the first housing 10 and the second housing 20 is improved, and at the same time, it is beneficial to improve the assembly efficiency of the vehicle-mounted camera 100.

[0063] The lens 30 is disposed on the first housing 10. The lens 30 is used to adjust the light. The lens 30 includes at least one lens. The lens 30 may have a fixed focal length or a variable focal length. When the lens 30 has a variable focal length, the lens 30 may further include a motor structure for driving one or more of the at least one lens to move. The embodiments of the present application are not specifically limited here.

[0064] The circuit board 40 is disposed in the accommodating cavity 25 and connected to the first housing 10. The circuit board 40 may be a printed circuit board 40 (PCBA) or a flexible circuit board 40 (FPC). In this embodiment, a positioning pin 12 is disposed inside the first housing 10, and the circuit board 40 is provided with a first through hole 42 adapted to the positioning pin 12. When the circuit board 40 is assembled with the first housing 10, the positioning pin 12 cooperates with the first through hole 42, so that the circuit board 40 can be accurately assembled with the first housing 10. It can be understood that in other embodiments, the circuit board 40 can also be disposed in the accommodating cavity 25 and connected to the second housing 20.

[0065] The photosensitive chip 50 is arranged on the side of the circuit board 40 facing the lens 30 and is arranged opposite to the lens 30. The photosensitive chip 50 is connected to the circuit board 40. The photosensitive chip 50 is used to receive the light adjusted by the lens 30, and convert the light signal in the light into an electrical signal and transmit the electrical signal to the circuit board 40 for imaging. The first electronic component 60 is arranged on the side of the circuit board 40 away from the lens 30 and is connected to the circuit board 40. The number of the first electronic component 60 can be multiple, and the first electronic component 60 can be a capacitor, an inductor, a resistor, a processor, etc. The first electronic component 60 can be a component that needs to be shielded in the vehicle camera 100.

[0066] The shielding film 70 is attached to the side of the circuit board 40 away from the lens 30 and completely covers the first electronic component 60. The shielding film 70 is a thermoplastic film. The shielding film 70 is completely attached to the circuit board 40 and completely covers the first electronic component 60 by hot air blowing. The hot air blowing method can be understood as continuously blowing hot air to the shielding film 70 to heat the shielding film 70. The shielding film 70 shrinks under the heating state. The molecular structure in the shielding film 70 changes by heating, and the molecular chain has activity. The shielding film 70 cools and fixes with the temperature decreases, forming a molecular orientation, so as to tightly wrap around the surface of the circuit board 40 and the first electronic component 60. The shielding film 70 completely covers the first electronic component 60, which can be understood as the shielding film 70 after heat shrinkage completely wraps the top surface and side surface of the first electronic component 60. It can be understood that the shielding film 70 can be a flexible film with shielding material attached therein. The film contains conductive materials and polymer materials, thereby forming a flexible structure that can achieve electromagnetic shielding. It can be understood that the shielding film 70 can specifically be a conductive film, a conductive adhesive film or a metallized porous film, wherein the conductive film is formed by coating a layer of metal foil on the film, using the metal foil as the base film, pasting a conductive film on the base film, and then pasting conductive ink on the film or coating a conductive material on the base film, and finally baking and curing it; the conductive adhesive film is formed by coating a conductive adhesive on a base film; and the metallized porous film is formed by rolling a metallized porous film on a base film.

[0067] In the above-mentioned vehicle-mounted camera 100, the photosensitive chip 50 and the first electronic component 60 are respectively arranged on two opposite sides of the circuit board 40, and the photosensitive chip 50 and the first electronic component 60 are arranged separately to avoid electromagnetic mutual influence between the photosensitive chip 50 and the first electronic component 60. By arranging a shielding film 70 on the side of the circuit board 40 away from the lens 30 and attaching the shielding film 70 to the circuit board 40 and completely covering the first electronic component 60 that needs to be electromagnetically shielded, the shielding film 70 completely covers the first electronic component 60 to achieve electromagnetic shielding for the first electronic component 60, avoiding the first electronic component 60 from being affected by external electromagnetic influences or electromagnetic induction interactions with other components, and also preventing the electromagnetic field generated by the first electronic component 60 from affecting other high-precision electronic components, which is conducive to improving the shielding effect. By limiting the shielding film 70 to a thermoplastic film, the thermoplastic film can be completely adhered to the circuit board 40 and the first electronic component 60 by hot air blowing, so that the assembly of the shielding film 70 is not affected by parameters such as space, position, and distance. The operation is simple, which is conducive to reducing shielding costs.

[0068] In this embodiment, the thickness of the shielding film 70 ranges from 0.035 mm to 1 mm, for example, the thickness of the shielding film 70 is 0.035 mm, 0.04 mm, 0.05 mm, 0.06 mm, 0.07 mm, 0.08 mm, 0.09 mm, 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, etc. In this way, by limiting the thickness range of the shielding film 70, on the one hand, the shielding film 70 can completely and tightly wrap the surface of the first electronic component 60, and on the other hand, the strength of the shielding film 70 is improved to avoid the shielding film 70 from being torn when the shielding film 70 is assembled. However, when the thickness of the shielding film 70 is less than 0.035 mm, firstly, the thickness of the shielding film 70 is too thin, the strength of the shielding film 70 is low, and the shielding film 70 is easily torn when assembling the shielding film 70. Secondly, the thickness of the shielding film 70 is too thin and difficult to process and produce. When the thickness of the shielding film 70 is greater than 1 mm, the thickness of the shielding film 70 is too thick, and the shielding film 70 shrinks unevenly when heated, resulting in the shielding film 70 being unable to tightly wrap all surfaces of the first electronic component 60, affecting the shielding effect.

[0069] In this embodiment, the ratio of the unfolded area of ​​the shielding film 70 to the shielding area of ​​the circuit board 40 is 1.2-1.5, and the shielding area of ​​the circuit board 40 is the shielding film 70 along the optical axis 200 of the vehicle camera 100 (see Figure 1) direction on the circuit board 40. For example, the ratio of the unfolded area of ​​the shielding film 70 to the shielding area of ​​the circuit board 40 is 1.2, 1.25, 1.3, 1.35, 1.4, 1.45, 1.5, etc. In this way, by limiting the ratio of the unfolded area of ​​the shielding film 70 to the shielding area of ​​the circuit board 40, on the first hand, the shielding film 70 can completely cover the first electronic component 60, and on the second hand, the cost of the shielding film 70 is saved, thereby reducing the shielding cost. However, when the ratio of the unfolded area of ​​the shielding film 70 to the shielding area of ​​the circuit board 40 is less than 1.2, the unfolded area of ​​the shielding film 70 is too small, and the shielding film 70 cannot completely cover the first electronic component 60 after heat shrinkage, affecting the shielding effect. When the ratio of the unfolded area of ​​the shielding film 70 to the shielding area of ​​the circuit board 40 is greater than 1.5, the unfolded area of ​​the shielding film 70 is too large, resulting in an increase in the cost of the shielding film 70.

[0070] In this embodiment, the vehicle-mounted camera 100 also includes a second electronic component 80, which is arranged on the side of the circuit board 40 away from the lens 30 and is spaced from the first electronic component 60, wherein the shielding film 70 is provided with an avoidance hole 72 adapted to the second electronic component 80 and used to avoid the second electronic component 80. The second electronic component 80 can be a component that does not need to be shielded in the vehicle-mounted camera 100, and the second electronic component 80 can be a wiring terminal, which is used to be electrically connected to the circuit board 40 and other components, so that the circuit board 40 and other components can be electrically connected. In this way, by opening the avoidance hole 72 on the shielding film 70, when the shielding film 70 is assembled, the shielding film 70 avoids the second electronic component 80 that does not need to be shielded through the avoidance hole 72, and the shielding film 70 only needs to cover the first electronic component 60 that needs to be shielded as much as possible, saving the cost of the shielding film 70, thereby reducing the shielding cost. Among them, the size of the avoidance hole 72 can be slightly larger than the size of the second electronic component 80.

[0071] In this embodiment, the vehicle-mounted camera 100 further includes a connector 90, which is connected to the second housing 20 and electrically connected to the circuit board 40. The connector 90 is exposed on the side of the second housing 20 away from the first housing 10, and the connector 90 can be embedded in the side of the second housing 20 away from the first housing 10. The connector 90 passes through one end of the second housing 20 and is electrically connected to the second electronic component 80, and the connector 90 is electrically connected to the circuit board 40 through the second electronic component 80. In this way, by providing the above-mentioned connector 90, the circuit board 40 of the vehicle-mounted camera 100 is electrically connected to other electronic components through the second electronic component 80 and the connector 90.

[0072] In this embodiment, the first shell 10 and the second shell 20, the lens 30 and the first shell 10, and the connector 90 and the second shell 20 can be laser welded, threaded or glued. The connection methods between the first shell 10 and the second shell 20, between the lens 30 and the first shell 10, and between the connector 90 and the second shell 20 can be completely the same or not completely the same, and the embodiment of the present application does not specifically limit this. In this way, by limiting the connection between the first shell 10 and the second shell 20, between the lens 30 and the first shell 10, and between the connector 90 and the second shell 20, it is beneficial to improve the connection stability between the structures in the vehicle-mounted camera 100. Among them, the laser welding connection method can also improve the sealing performance between the first shell 10 and the second shell 20, between the lens 30 and the first shell 10, and between the connector 90 and the second shell 20, thereby improving the sealing performance of the vehicle-mounted camera 100.

[0073] In this embodiment, a barb structure 92 is provided on the outer periphery of the connector 90, and a guide member 94 is also provided on the outer periphery of the connector 90. The number of the guide members 94 can be two, and the two guide members 94 are symmetrically arranged. The two guide members 94 and the barb structure 92 are arranged at intervals along the outer periphery of the connector 90. The connector 90 is connected to the external structure by hook and card through the barb structure 92, and the connector 90 can be accurately connected to the external structure through the guide member 94. In this way, by providing the barb structure 92 on the outer periphery of the connector 90, the connector 90 is connected to the external structure by hook and card, and the connection stability between the vehicle-mounted camera 100 and the external structure is improved; by providing the above-mentioned guide member 94, the vehicle-mounted camera 100 can be accurately connected to the external structure. It can be understood that in other embodiments, the number of guide members 94 can also be one, three or more, and the embodiment of the present application does not make specific limitations on this.

[0074] In this embodiment, a positioning column 22 and a positioning hole 24 spaced apart from the positioning column 22 are provided on the side of the second shell 20 facing away from the first shell 10. The number of the positioning column 22 and the positioning hole 24 are both two. The two positioning columns 22 are provided along one of the diagonal angles on the second shell 20, and the two positioning holes 24 are provided along the other diagonal angle on the second shell 20. In this way, by providing the positioning column 22 on the second shell 20, it is convenient to precisely connect the vehicle-mounted camera 100 with the external structure; by providing the positioning hole 24 on the second shell 20, it is convenient to allow a screw to pass through the positioning hole 24 and connect with the circuit board 40 and the first shell 10, so that the first shell 10, the circuit board 40 and the second shell 20 are fixedly connected. In a specific embodiment, two connecting holes 14 arranged along the diagonal angles are provided inside the first shell 10, and two second through holes 44 arranged along the diagonal angles are provided on the circuit board 40. The connecting holes 14 can be threaded holes. In this way, when the first shell 10, the circuit board 40 and the second shell 20 need to be fixedly connected, the screw passes through the positioning hole 24 and the second through hole 44 to be threadedly connected with the connecting hole 14, so that the first shell 10, the circuit board 40 and the second shell 20 are fixedly connected, and the connection method of the vehicle camera 100 is simple.

[0075] It is understandable that in other embodiments, the number of positioning posts 22 and positioning holes 24 can also be one, three or more, and the number of positioning posts 22 and positioning holes 24 can be exactly the same or not exactly the same, and the embodiments of the present application do not specifically limit this.

[0076] The embodiment of the present application also provides a vehicle (not shown). The vehicle includes a vehicle body (not shown) and a vehicle-mounted camera 100 as described in the above technical solution, and the vehicle-mounted camera 100 is arranged on the vehicle body. Specifically, the vehicle-mounted camera 100 can be arranged in front of the front windshield of the vehicle body, in front of the front of the vehicle body, below the rearview mirror of the vehicle body, behind the rear of the vehicle body, or at other positions of the vehicle body. The vehicle-mounted camera 100 can be used to obtain images around the vehicle so that the vehicle can monitor the surrounding environment or realize automatic driving.

[0077] In the above-mentioned vehicle, the photosensitive chip 50 and the first electronic component 60 in the vehicle-mounted camera 100 are respectively arranged on the opposite sides of the circuit board 40, and the photosensitive chip 50 and the first electronic component 60 are arranged separately to avoid electromagnetic mutual influence between the photosensitive chip 50 and the first electronic component 60. By arranging a shielding film 70 on the side of the circuit board 40 of the vehicle-mounted camera 100 away from the lens 30 and attaching the shielding film 70 to the circuit board 40 and completely covering the first electronic component 60 that needs to be electromagnetically shielded, the shielding film 70 completely covers the first electronic component 60 to achieve electromagnetic shielding for the first electronic component 60, avoiding the first electronic component 60 from being affected by external electromagnetic influences or electromagnetic induction mutual influences with other components in the vehicle body, and also preventing the electromagnetic field generated by the first electronic component 60 from affecting other high-precision electronic components of the vehicle body, which is conducive to improving the shielding effect. By limiting the shielding film 70 to be a thermoplastic film, the thermoplastic film can be completely attached to the circuit board 40 and the first electronic component 60 by hot air blowing, so that the assembly of the shielding film 70 is not affected by parameters such as space, position, and distance, and the operation is simple, which is conducive to reducing the shielding cost; by opening the avoidance hole 72 on the shielding film 70, the second electronic component 80 that does not need to be shielded can be avoided, thereby saving the cost of the shielding film 70 and further reducing the shielding cost; by setting the connector 90, the vehicle-mounted camera 100 is fixedly connected and electrically connected to the vehicle body.
