[0030] Some embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0031] As described in the background technology, customers currently have diverse needs. Even for the same vehicle-mounted camera, customers have very different needs. If a separate mold or production line is used to meet each need, the production time will be greatly extended and the production cost will be increased.

[0032] Therefore, the utility model creatively proposes a vehicle-mounted camera, which acts as a transfer by adding a support plate between the circuit board and the front shell, thereby facilitating the installation of the circuit board; and at least two mounting positions are set on the support plate, and the circuit board is detachably installed on one of the mounting positions through a connecting piece, so that the support plate can match different circuit boards, thereby meeting the needs of different customers, improving the utilization efficiency of the front shell of the same vehicle-mounted camera, and achieving the effect of reducing costs and increasing efficiency.

[0033] The present invention will be described in detail below through specific embodiments.

[0034] This embodiment provides a vehicle-mounted camera, referring to Figure 1 As shown, the vehicle-mounted camera includes a front shell 1, a rear shell 2, a support plate 3 and a circuit board 4. The front shell 1 and the rear shell 2 are connected to form an installation space 5, and the support plate 3 and the circuit board 4 are both arranged in the installation space 5.

[0035] The front shell 1 and the rear shell 2 are fixedly connected by welding, and specifically laser welding can be selected to improve the sealing of the connection between the front shell 1 and the rear shell 2, and ensure the reliability of the vehicle-mounted camera in harsh environments. It can be understood that other connection methods can also be used to fix the front shell 1 and the rear shell 2 as needed, such as bolt connection, buckle connection, etc.

[0036] The support plate 3 is connected to the front shell 1 and / or the rear shell 2 , and can be adjusted according to structural strength and installation requirements. In this embodiment, the support plate 3 is connected to the front shell 1 .

[0037] The support plate 3 is provided with at least two mounting positions, and the circuit board 4 is detachably mounted on one of the mounting positions via the connecting member 6 .

[0038] It should be noted that the connection methods between the connecting member 6 and the mounting position include snap connection, pin connection, threaded connection, etc.; illustratively, a first hole is provided at the mounting position, and a second hole is provided at the connecting member 6. After aligning the first hole with the second hole, the pin is inserted into the first hole and the second hole to achieve connection.

[0039] In this embodiment, refer to Figure 1 and Figure 2 As shown, the mounting position includes a first mounting hole 31, which is distributed based on a preset rule. A second mounting hole 41 is provided on the circuit board 4, and the second mounting hole 41 corresponds to at least one first mounting hole 31. The second mounting hole 41 is connected to the corresponding first mounting hole 31 through a connecting member 6.

[0040] Specifically, during installation, the support plate 3 is first installed on the front shell 1, and then the first mounting holes 31 of corresponding quantity and position are selected on the support plate 3 according to the distribution position, size and other parameters of the second mounting holes 41 on the circuit board 4, and then the connecting member 6 is installed in the first mounting hole 31, and the connecting member 6 is installed in the second mounting hole 41, and then the connecting member 6 is connected to the circuit board 4, so that the circuit board 4 is installed on the support plate 3.

[0041] The preset rules may be set based on the support plate 3 or the circuit board 4, or may even be set in combination with the two.

[0042] In an alternative embodiment, the preset rule is set based on the circuit board 4. The preset rule includes: the first mounting hole 31 on the support plate 3 corresponds to the second mounting holes 41 on at least two different circuit boards 4 respectively.

[0043] It can be understood that the different circuit boards 4 here mainly refer to the different positions of the second mounting holes 41 on the circuit boards 4, and can be further understood as different installation methods of the circuit boards 4.

[0044] Specifically, first obtain the relative positions of the second mounting holes 41 on at least two circuit boards 4, and then based on the relative positions, process the number and positions of the first mounting holes 31 on the support plate 3. During processing, select an axis on the circuit board 4 as a reference, then select an axis on the support plate 3, and make the axes of the circuit board 4 and the support plate 3 coincide, and then process the first mounting hole 31 corresponding to one circuit board 4 on the support plate 3, so as to ensure the coaxiality of the second mounting hole 41 and the first mounting hole 31 when installing the circuit board 4. Similarly, the first mounting holes 31 on the support plate 3 corresponding to the second, third or even Nth circuit board 4 can be processed in the above manner. Wherein, N≥1, and N is a positive integer. Based on the above-mentioned design rules for the first mounting holes 31, the design of the support plate 3 can be more flexibly adapted to the circuit board 4 used by the customer.

[0045] Furthermore, the vehicle-mounted camera also includes a lens, which is disposed in the front shell 1 and is integrally formed with the front shell 1 .

[0046] The circuit board 4 and the lens need to be electrically connected via a wiring harness (not shown). In order to shorten the length of the wiring harness, a positioning hole 32 is drilled through the support plate 3. The positioning hole 32 is used to align the support plate 3 with the front shell 1 and / or the rear shell 2.

[0047] In this embodiment, the positioning hole 32 is used to align the support plate 3 with the front shell 1; specifically, when installing the support plate 3, the axis of the positioning hole 32 can be aligned with the central axis of the front shell 1, or the positioning hole 32 can be aligned with the axis of the lens. It can be understood that the user can select the axis to be aligned with the axis of the positioning hole 3 according to factors such as installation requirements.

[0048] Further, in another alternative embodiment, the preset rule is set based on the support plate 3. The preset rule includes: at least part of the first mounting holes 31 on the support plate 3 are symmetrical or axially symmetrical about the positioning hole 32.

[0049] Specifically, with the positioning hole 32 as the center, a circuit board 4 without a second mounting hole 41 is selected, and the central axis of the circuit board 4 is made to coincide with the axis of the positioning hole 32. Then, according to the distribution position of the first mounting hole 31 on the support plate 3, the corresponding second mounting hole 41 is processed on the circuit board 4 to ensure the coaxiality of the first mounting hole 31 and the second mounting hole 41. Similarly, the second mounting hole 41 of the second, third and even Mth circuit board 4 corresponding to the support plate 3 can be processed in the above manner. Wherein, M≥1, and M is a positive integer. Based on the above-mentioned design rules of the second mounting hole 41, the design time of the installation position of the circuit board 4 can be saved, and the specifications of the support plate 3 are unified, thereby reducing the production and manufacturing cost of the vehicle-mounted camera.

[0050] Furthermore, the preset rules are combined with the circuit board 4 and the support plate 3 for simultaneous design, which not only takes into account the flexible adaptability of the support plate 3 to the circuit board 4, but also makes the partial design of the support plate 3 universal, thereby ensuring that the vehicle camera is easy to customize while reducing the production cost of the vehicle camera.

[0051] Further, in some examples, the connector 6 is adapted to be inserted into the first mounting hole 31; or the connector 6 is threadedly connected to the first mounting hole 31. In this embodiment, the connector 6 is threadedly connected to the first mounting hole 31.

[0052] In addition, in some examples, for example, to save assembly time and improve installation efficiency, the connector 6 and the support plate 3 are an integral structure. That is, the connector 6 and the support plate 3 can be integrally formed, or before the support plate 3 is installed, the connector 6 and the support plate 3 are connected by welding or other connection methods.

[0053] In a preferred example, referring to Figure 3As shown, at least one movable channel 33 is provided through the support plate 3, and the movable channel 33 includes at least two adjacent first mounting holes 31. Specifically, when the second mounting hole 41 is matched with the corresponding first mounting hole 31 on the support plate 3, due to factors such as machining accuracy or assembly error and the size of the vehicle-mounted camera, after the connector 6 is installed in the first mounting hole 31, if the coaxiality deviation between the second mounting hole 41 and the first mounting hole 31 on the circuit board 4 to be installed is large, resulting in difficulty in installing the circuit board 4, then it may be considered to move the connector 6 in the movable channel 33 to facilitate installation of the circuit board 4.

[0054] In this embodiment, the movable channel 33 includes four first mounting holes 31 along the same linear direction. In order to improve the installation convenience of the connecting member, the width of the movable channel 33 is generally equal to the diameter of the first mounting hole 31.

[0055] It should be noted that, under the premise of using the movable channel 33 , the connecting member 6 and the support plate 3 can be connected in a detachable manner such as bolt connection.

[0056] In some examples, there is a first preset gap 43 between the connector 6 and the second mounting hole 41. In some examples, the first preset gap 43 is ≤ 0.3 mm. It should be noted that since the photosensitive chip on the subsequent circuit board 4 and the lens focus position are controlled by active focusing, the existence of the first preset gap 43 can be used for active focusing to absorb deviations to improve the imaging quality of the lens.

[0057] In this embodiment, the first preset gap 43 is 0.3 mm.

[0058] In some examples, the support plate 3 and the front shell 1 are assembled by limiting the outer shape, that is, by limiting the second preset gap 34 between the support plate 3 and the front shell 1. In some examples, the second preset gap 34 includes 0.05-0.1 mm.

[0059] To improve the convenience of installation, refer to Figure 1 As shown, a bearing surface 11 for supporting the support plate 3 is provided in the front shell 1, and the cross-sections of the support plate 3 and the bearing surface 11 are designed to be similar in shape. A third mounting hole 35 is provided on the support plate 3, and a threaded member 8 is passed through the third mounting hole. A fourth mounting hole 12 threadedly connected to the threaded member 8 is provided in the front shell 1 to connect the support plate 3 and the front shell 1.

[0060] In addition, the positions and sizes of the third mounting holes 35 on different support plates 3 can be unified so that different support plates 3 can be installed on the front shell 1 of the same vehicle-mounted camera, and different support plates 3 can respectively correspond to the second mounting holes 41 on circuit boards 4 of various specifications, thereby further improving the installation adaptability of the same vehicle-mounted camera to different circuit boards 4.

[0061] There are many ways to connect the connector 6 to the circuit board 4, including welding, threaded connection, clamping, etc.

[0062] In order to improve the connection stability between the circuit board 4 and the connecting member 6, in this embodiment, the connecting member 6 and the circuit board 4 are connected by a metal having a preset melting point. Figure 1 As shown, a metal to-be-melted piece 7 having a predetermined melting point and corresponding to the number of the connecting pieces 6 is provided on one side of the circuit board 4 away from the support plate 3, and the to-be-melted piece 7 is provided on the outer side wall of the corresponding connecting piece 6. During installation, the solid to-be-melted piece 7 is melted by heat and partially enters the corresponding second mounting hole 41 to fill the first predetermined gap 43 between the corresponding connecting piece 6 and the second mounting hole 41, and then the melted to-be-melted piece 7 is cooled and solidified to fix the circuit board 4 and the connecting piece 6, thereby increasing the connection strength between the connecting piece 6 and the circuit board 4 by filling the gap.

[0063] exist Figure 1 In the figure, the left side shows the state where the solid part to be melted 7 is sleeved on the connection 7, and the right side shows the state where the part to be melted 7 is melted into the first preset gap 43 and then solidified.

[0064] The melted part 7 can be made of one of the metals with a melting point lower than 240°C. It is understood that the metals mentioned here include alloys. In this embodiment, the melted part 7 is made of tin, but it is understood that tin is only an exemplary and non-restrictive description of the material of the melted part 7 in the embodiment of the present application. Without violating the concept of the utility model of the present application, any known type of material that meets the preset melting point can be used to manufacture the melted part 7.
