Description

Technical Field

[0001] This utility model relates to the field of vehicle camera technology, specifically to a vehicle camera structure with TOF. Background Technology

[0002] With the continuous improvement of automotive intelligent technology research, cameras are gradually being widely used in cars, mainly including reversing rearview cameras and surveillance cameras. For example, by installing a reversing rearview camera at the back of the car, the camera captures video images and transmits them to the in-vehicle host display screen for display, allowing the driver to see the status behind the car. Surveillance cameras can be used for theft prevention, so in-vehicle cameras are being used by more and more users.

[0003] Existing automotive cameras on the market mainly consist of a housing and a camera fixed inside the housing. The housing has glass to allow the camera to capture the surrounding environment through the glass. However, the camera modules in existing automotive cameras are relatively large, requiring board-to-board connections during installation. This causes the RGB module lens to protrude from the front housing, affecting aesthetics. Furthermore, existing automotive cameras have poor heat dissipation performance. Therefore, we propose a new TOF-integrated automotive camera structure. Utility Model Content

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a structure with a TOF vehicle-mounted camera, comprising: a rear shell, wherein the side wall of the rear shell is provided with multiple heat dissipation fins for easy heat dissipation, and a through groove is opened on the top of the rear shell; a front shell, wherein the front shell is fixedly connected to the rear shell by six screws, and three through mounting grooves are opened on one side of the front shell; an RFPC-A board, wherein the RFPC-A board includes a TOF camera module and an RGB module, wherein the RGB module end of the RFPC-A board is fixedly connected to the inner cavity of the rear shell by two screws, and the TOF module end of the RFPC-A board is fixedly connected to the inner cavity of the rear shell by four screws; an RFPC-B board, wherein the RFPC-B board is fastened to the RFPC-A board by a connector; and glass, wherein the glass is fixedly connected to the inner cavity of the mounting groove of the front shell by waterproof adhesive.

[0006] As a further description of the above technical solution, the first waterproof sealing ring is fixedly connected to the opening of the rear shell, and the second waterproof sealing ring is fixedly connected to the inner cavity of the through groove at the top of the rear shell.

[0007] As a further description of the above technical solution, the RFPC-B board penetrates the mounting groove at the bottom of the front shell, and the RFPC-B board is fixedly connected to the inner cavity of the front shell by two screws.

[0008] As a further description of the above technical solution, the heat-dissipating silicone is fixedly connected to the inner cavity of the mounting groove at the bottom of the front shell.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] In this invention, by designing the PCB board as a rigid-flex PCB, staggered installation is possible, eliminating the need for board-to-board connectors, resulting in a more compact structure and reducing the overall size of the camera module. Simultaneously, the staggered installation of the RFPC-A boards allows all boards to be attached to the rear shell, with exposed copper at the attachment points for better heat dissipation. This staggered installation also allows the RGB module to be positioned below, preventing the RGB module lens from protruding from the front shell and affecting aesthetics. Furthermore, multiple heat dissipation fins are provided on the outer wall of the rear shell to further improve heat dissipation performance, and three types of glass are used to correspond to different modules, effectively preventing light leakage and affecting distance measurement.

[0015] To make the technical means, creative features, and objectives of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments.

[0016] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] Please see Figure 1-3This utility model provides a technical solution: a structure with a TOF vehicle-mounted camera, comprising: a rear shell 1, the side wall of which is provided with multiple heat dissipation fins for good heat dissipation performance, and a through slot on the top of the rear shell 1; a front shell 6, which is fixedly connected to the rear shell 1 by six screws 8, and has three through mounting slots on one side; and an RFPC-A board 4, which includes a TOF camera module and an RGB module. The RGB module end on the RFPC-A board 4 is fixedly connected to the inner cavity of the rear shell 1 by two screws 8, and the TOF module end on the RFPC-A board 4 is fixedly connected to the inner cavity of the rear shell 1 by four screws 8. By designing the PCB board as a rigid-flex board, staggered installation is possible, eliminating the need for board-to-board mounting. The connectors make the structure more compact, reducing the overall size of the camera module. Meanwhile, the RFPC-A board 4 can be installed in a staggered manner, allowing all boards of the RFPC-A board 4 to be attached to the rear shell 1. The copper exposed at the attachment points of the boards and the rear shell 1 allows for better heat dissipation. The staggered installation of the RFPC-A board 4 also allows the RGB module to be positioned below, preventing the RGB module lens from protruding from the front shell and affecting aesthetics. The RFPC-B board 7 is connected to the RFPC-A board 4 via a connector. The glass 9 is fixed to the inner cavity of the front shell 6 mounting slot using waterproof adhesive, and a pressing machine is used to press the waterproof adhesive and the glass 9 into the inner cavity of the front shell 6 mounting slot to ensure a tight fit between the glass 9 and the inner cavity. Three types of glass are used: the glass corresponding to the RGB module is a full-pass glass, and the glass corresponding to the TOF module and VCSEL is a narrow-band 940nm glass. Since this module is used in automotive applications, the requirements are relatively high, so the glass corresponding to the TOF module and the glass corresponding to the VCSEL are designed separately to avoid light leakage and affect the ranging.

[0019] Specifically, such as Figure 2 As shown, the RFPC-B board 7 passes through the mounting slot at the bottom of the front shell 6, and is fixedly connected to the inner cavity of the front shell 6 by two screws 8. Thermal silicone 5 is fixedly connected to the inner cavity of the mounting slot at the bottom of the front shell 6 to facilitate heat dissipation of the RFPC-B board 7.

[0020] Specifically, such as Figure 3 As shown, waterproof sealing ring 2 is fixedly connected to the opening of the rear shell 1, and waterproof sealing ring 3 is fixedly connected to the inner cavity of the top through groove of the rear shell 1, thereby improving the waterproof performance of this device.

[0021] It should be noted that this utility model is a structure for a vehicle-mounted camera with TOF capability. During installation, by designing the PCB board as a rigid-flex board, staggered installation is possible, eliminating the need for board-to-board connectors, making the structure more compact and reducing the overall size of the camera module. Simultaneously, the staggered installation of the RFPC-A board 4 allows all boards of the RFPC-A board 4 to be attached to the rear shell 1, with exposed copper at the attachment points for better heat dissipation. The staggered installation of the RFPC-A board 4 also allows the RGB module to be positioned below, preventing the RGB module lens from protruding from the front shell and affecting aesthetics. Furthermore, multiple heat dissipation fins are provided on the outer wall of the rear shell to further improve heat dissipation performance. The waterproof performance of this device is improved through waterproof sealing rings 2 and 3. Three types of glass are used: the glass corresponding to the RGB module is a full-pass glass, and the glass corresponding to the TOF module and VCSEL is a narrow-band 940nm glass. Since this module is used in automotive applications, the requirements are relatively high, so the glass corresponding to the TOF module and the glass corresponding to the VCSEL are designed separately to avoid light leakage and affect the ranging.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
