Description

Technical Field

[0001] This application relates to the field of mechanical design and manufacturing, and in particular to a rear cover for an in-vehicle camera. Background Technology

[0002] Driver Monitor System (DMS) cameras are typically housed in a single-piece housing and mounted on the A-pillar of a car via this housing.

[0003] An integrated housing bracket typically includes a front camera cover and a rear camera cover, with symmetrical "ear" structures on both sides of the front or rear camera cover. These "ear" structures have mounting holes, the center lines of which are parallel to the center lines of the mounting holes for locking the front and rear covers, for mounting the integrated housing bracket to the vehicle body components.

[0004] Because the ear-shaped structure of the integrated housing bracket extends to both sides from the front or rear cover of the camera, the entire integrated housing bracket occupies a relatively large space. In situations where the space within the bodywork's cavity is limited or narrow, such an integrated housing bracket cannot be installed. Utility Model Content

[0005] This application discloses a vehicle camera rear cover and camera module, which can be installed inside the space-constrained body cavity of the vehicle body.

[0006] To achieve the above objectives, in a first aspect, embodiments of this application disclose a vehicle-mounted camera rear cover, comprising:

[0007] The rear cover body is configured to cooperate and connect with the front cover of the vehicle camera to jointly form the camera housing, which is used to accommodate the camera.

[0008] The cantilever has at least two cantilever arms, each of which is located on the same side of the rear cover body in a first direction, and the first end of the cantilever arm is connected to the rear cover body, and the second end of the cantilever arm extends away from the rear cover body. The at least two cantilever arms are respectively arranged on opposite sides of the rear cover body in a second direction, and the first direction and the second direction are intersecting each other.

[0009] The mounting part is connected to the second end of each of the cantilever arms. The mounting part is configured to connect with the mounting structure of the vehicle body so that the rear cover of the vehicle camera is fixed to the vehicle body.

[0010] Optionally, at least one of the cantilever arms extends in a straight line; or, at least one of the cantilever arms is bent such that the mounting portion is located outside the rear cover body, and at least a portion of the structure of the mounting portion is located outside the plane of the rear cover body.

[0011] Optionally, at least a portion of the cantilever structure is located outside the edge of the rear cover body in a first direction.

[0012] Optionally, there are two cantilever arms, and the two cantilever arms are respectively connected to opposite ends of the same side of the rear cover body.

[0013] Optionally, the cantilever is plate-shaped, and the thickness of the cantilever is between 1.5 mm and 2 mm.

[0014] Optionally, the rear cover body forms a receiving cavity with an opening at one end, the opening being configured to face the vehicle camera front cover so that the receiving cavity is closed when the vehicle camera front cover and the vehicle camera rear cover are connected to each other.

[0015] The cantilever arms are all located on the side of the opening.

[0016] Optionally, the rear cover body is provided with a first mounting hole, which is configured to allow a first fastener to pass through the first mounting hole to connect the rear cover body and the vehicle camera front cover via the first fastener.

[0017] Optionally, the mounting part is a mounting plate, and the mounting plate is provided with a second mounting hole. The second mounting hole is configured to allow a second fastener to pass through the second mounting hole so as to connect the mounting structure of the vehicle camera rear cover and the vehicle body through the second fastener. The axial direction of the second mounting hole and the axial direction of the first mounting hole have an included angle.

[0018] Optionally, the mounting part is a mounting clip, which is used to engage with the mounting structure of the vehicle body.

[0019] Secondly, embodiments of this application disclose a camera module, including:

[0020] The camera itself;

[0021] A camera housing, comprising a front cover for a vehicle camera and a rear cover for a vehicle camera according to a first aspect, wherein the front cover and the rear cover together form a receiving cavity, and the camera body is disposed in the receiving cavity.

[0022] Compared with the prior art, the beneficial effects of this application are at least as follows:

[0023] The vehicle camera rear cover and camera module provided in this application embodiment separate the rear cover body and the mounting part by setting a cantilever connecting the rear cover body and the mounting part. When the main body of the camera housing is accommodated inside the cavity of the vehicle body with limited space, the mounting part can be set outside the cavity, thereby reducing the space occupied by the camera housing inside the cavity. By setting at least two cantilever arms on the same side of the rear cover body in a first direction and respectively set on opposite sides of the rear cover body in a second direction, it can be ensured that the end of the rear cover body not connected to the cantilever arms can be set at a certain angle inside the cavity of the vehicle body, and the camera housing is set inside the cavity of the vehicle body in a manner similar to "suspension" by the cantilever arms, while the rear cover body is fixed on both sides outside the cavity of the vehicle body.

[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0041] In this invention, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0042] Furthermore, in addition to indicating direction or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this utility model according to the specific circumstances.

[0043] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0044] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0045] Vehicle cameras such as DMS cameras and Occupant Monitoring System (OMS) cameras are typically housed in an integrated housing bracket, which is then mounted to the A-pillar, center console, or other parts of the vehicle body to track the status of the driver and passengers.

[0046] An integrated camera housing typically includes a front camera cover and a rear camera cover, and features a pair of "ear" structures on either side of the front or rear camera cover. For example... Figure 1 The image shows a camera rear cover 120 with an existing integrated housing bracket. It has ear structures 50 on both sides, each with mounting holes 51. The integrated housing bracket can be installed onto the vehicle body by fixing screws through the mounting holes 51 to studs on the vehicle body assembly. Because the ear structures 50 on both sides of the integrated housing bracket extend outwards, the entire integrated housing bracket occupies a large space. Therefore, it cannot be installed inside the vehicle body assembly cavity where space is limited or narrow.

[0047] This application separates the mounting portion of the vehicle camera rear cover from the main body of the rear cover by incorporating a cantilever. This allows the mounting portion to secure the camera housing externally to the cavity of the vehicle body component when the main body of the camera housing is housed within the cavity. The camera can then be mounted inside the cavity of the vehicle body component in a "suspended" manner via the outward-extending cantilever, without occupying internal space. Therefore, it achieves the goal of installing a vehicle camera inside the limited or narrow cavities of vehicle body components.

[0048] Figure 2 This is a schematic diagram of the structure of the vehicle-mounted camera rear cover 100 according to an embodiment of this application. Figure 2 As shown, the vehicle camera rear cover 100 according to an embodiment of this application includes:

[0049] The rear cover body 10 is configured to cooperate and connect with the front cover of the vehicle camera to jointly form the camera housing, which is used to house the camera.

[0050] The cantilever 20 is at least two, and each cantilever 20 is located on the same side of the rear cover body 10 in the first direction A. The first end 21 of the cantilever 20 is connected to the rear cover body 10, and the second end 22 of the cantilever 20 extends away from the rear cover body 10. At least two cantilever 20 are respectively arranged on opposite sides of the rear cover body 10 in the second direction B. The first direction A and the second direction B are intersected.

[0051] Mounting part 30 is connected to the second end 22 of each cantilever 20. Mounting part 30 is configured to connect with the mounting structure of the vehicle body so that the vehicle camera rear cover 100 is fixed to the vehicle body.

[0052] like Figure 2 As shown, in the vehicle camera rear cover 100 according to an embodiment of this application, the rear cover body 10 has a generally square structure. In other embodiments, the shape of the rear cover body 10 can also be hexagonal, circular, or other shapes adapted to the front cover of the vehicle camera, so that when the rear cover body 10 and the front cover of the vehicle camera are combined and connected together, a camera housing for accommodating the camera can be formed. The rear cover body 10 can be a plate-like structure or a cavity with a certain accommodating space. The rear cover body 10 and the front cover of the vehicle camera can be connected by various methods such as screw fastening and snap-fit ​​engagement. Therefore, the rear cover body 10 can be provided with connecting components such as slots, snaps, or mounting holes for fasteners to pass through. In the vehicle camera rear cover 100 according to an embodiment of this application, the connecting component is a mounting hole.

[0053] The vehicle camera rear cover 100 according to an embodiment of this application includes two cantilever arms 20. The first end 21 of each cantilever arm 20 is connected to the rear cover body 10, and the second end 22 extends away from the rear cover body 10, such that both cantilever arms 20 are located on the same side of the rear cover body 10 in a first direction A, and the two cantilever arms 20 are respectively disposed on opposite sides of the rear cover body 10 in a second direction B. Figure 2As shown, in this embodiment, the first direction A is the extension direction of the long side of the rear cover body 10, and the second direction B is the extension direction of the short side of the rear cover body 10. The first direction A and the second direction B are perpendicular to each other. Both cantilever arms 20 are located at one end of the rear cover body 10 along the first direction A, so that the other end of the rear cover body 10 along the first direction A occupies less space because it is not connected to the cantilever arms 20. When the internal cavity space of the vehicle body fitting is limited, the end of the rear cover body 10 without the cantilever arms connected along the first direction A can be set at a certain angle inside the cavity of the vehicle body fitting. The two cantilever arms 20 are respectively located on both sides of the short side of the rear cover body 10, so that the end of the rear cover body 10 connected to the cantilever arms along the first direction A is outside the cavity of the vehicle body fitting. The main body of the camera housing is set inside the cavity of the vehicle body fitting in a manner similar to "suspension" by the two cantilever arms 20, and the rear cover body 10 is fixed on both sides outside the cavity of the vehicle body fitting.

[0054] In other embodiments, the number of cantilever 20 may be more than two, and the multiple cantilever 20 may be located in the same plane or in different planes. These cantilever 20 only need to be located on the same side of the rear cover body 10 in the first direction A and respectively disposed on opposite sides of the rear cover body 10 in the second direction B. The first direction A may be the extension direction of the long side of the rear cover body 10 or form a certain angle with the extension direction of the long side; or, when the rear cover body 10 is circular, the first direction A may be the direction of one of the diameters, which is not limited here. The second direction B may be perpendicular to the first direction A, or form an acute angle or an obtuse angle with the first direction A, which is not limited here.

[0055] The mounting part 30 is connected to the second end 22 of each cantilever 20 and is used to connect with the mounting structure of the vehicle body, thereby connecting the vehicle camera rear cover 100 with the vehicle body fittings. The mounting part 30 can be connected to the vehicle body fittings via mounting holes or clips, or the mounting part 30 can be other types of mounting structures.

[0056] In the vehicle camera rear cover 100 according to an embodiment of this application, the cantilever 20 is a plate-shaped or strip-shaped structure with a certain degree of toughness. To ensure the mechanical strength and lightweight of the cantilever 20, the material of the cantilever 20 can be die-cast aluminum alloy (ADC), such as the Japanese grade ADC12 (the domestic alloy grade is YZAlSi). 11 The rear cover body 10, cantilever 20, and mounting part 30 can be separate parts, and connected by welding, riveting, or mounting structure; the components of the vehicle camera rear cover 100 can also be integrally die-cast.

[0057] According to an embodiment of this application, the vehicle camera rear cover 100 is separated from the mounting portion 30 by providing a cantilever 20 connecting the rear cover body 10 and the mounting portion 30. When the main body of the camera housing is accommodated inside a cavity with limited space in the vehicle body fitting, the mounting portion 30 can be disposed outside the cavity, thereby reducing the space occupied by the camera housing inside the cavity. By positioning at least two cantilever 20s on the same side of the rear cover body 10 in the first direction A and respectively disposed on opposite sides of the rear cover body 10 in the second direction B, it can be ensured that the end of the rear cover body 10 not connected to the cantilever 20 can be disposed at a certain angle inside the cavity of the vehicle body fitting, and the camera housing is "suspended" inside the cavity of the vehicle body fitting by the cantilever 20, while the rear cover body 10 is fixed on both sides outside the cavity of the vehicle body fitting.

[0058] Optionally, at least one cantilever 20 extends in a straight line; or, at least one cantilever 20 is bent such that the mounting portion 30 is located outside the rear cover body 10, and at least a portion of the structure of the mounting portion 30 is located outside the plane of the rear cover body 10.

[0059] Specifically, the cantilever 20 is typically a strip-shaped or plate-shaped structure, and can be configured to extend from its first end 21 and extend in a straight line to its second end 22. In the vehicle camera rear cover 100 according to an embodiment of this application, one of the cantilever 20 extends in a straight line along a second direction B. In other embodiments, the cantilever 20 may also extend in a straight line along other directions.

[0060] Alternatively, the cantilever 20 can also be configured to be bent. For example, the cantilever 20 can be configured to be "L" or "U" shaped, and the plane on which the "L" or "U" shaped cantilever 20 is located can be at a certain angle to the plane on which the back cover body 10 is located; or, when the cantilever 20 is located on the plane on which the back cover body 10 is located, the end of the "L" or "U" shaped cantilever 20 can be connected to the mounting part 30 outside the plane on which the back cover body is located through a connecting part; or, the cantilever 20 can be configured to be a more complex three-dimensional curved shape, without limitation, as long as the mounting part 30 is located outside the back cover body 10, and at least a part of the structure of the mounting part 30 is located outside the plane on which the back cover body 10 is located.

[0061] like Figure 2As shown, in the vehicle camera rear cover 100 according to an embodiment of this application, one of the cantilever arms 20 is configured to first extend a certain distance along the second direction B and then bend at a certain angle, for example, 90 degrees, and then continue to extend along the first direction A; the mounting portion 30 is connected to the end of the cantilever arm 20 at a certain angle to the plane of the rear cover body 10. A connecting portion may be provided between the mounting portion 30 and the cantilever arm 20, and the connecting portion is at a certain angle to the cantilever arm 20 and the mounting portion 30 respectively (for example, the connecting portion is perpendicularly connected to the cantilever arm 20 and the mounting portion 30 respectively), for connecting the mounting portion 30 to the outside of the plane of the rear cover body, and at the same time, the connecting portion serves as a reinforcing structure to strengthen the cantilever arm 20.

[0062] By designing the cantilever 20 as a straight extension, its design simplifies the process by enabling it to directly connect the mounting portion 30, corresponding to the vehicle body mounting structure, to the rear cover body 10. Therefore, the design and manufacturing of the cantilever 20 are relatively simple. Conversely, when the cantilever 20 is bent, the bending of the cantilever 20 avoids complex structures on the vehicle body components. Furthermore, bending and extending the cantilever 20 allows the mounting portion 30 to be positioned more ideally, thus better aligning with the vehicle body's mounting structure to secure the vehicle camera rear cover 100.

[0063] When the camera housing is installed inside the cavity of the hand component, in order to reduce the space occupied by the camera housing, the mounting part 30 needs to be installed outside the cavity and connected to the mounting structure of the vehicle body outside the cavity. Therefore, when the camera housing is installed inside the cavity of the hand component, the cantilever 20 should ensure that the mounting part 30 can be located outside the cavity through the extended cantilever 20.

[0064] Optionally, at least a portion of the structure of the cantilever 20 is located outside the edge of the rear cover body 10 in the first direction A.

[0065] At least a portion of the cantilever 20 is located outside the edge of the rear cover body 10 in the first direction A. This can be achieved by having a certain distance between the extended position of the cantilever 20 and the outer edge of the rear cover body 10 in the first direction A, for example, by having the cantilever 20 extend along the first direction A. Furthermore, when the extended position of the cantilever 20 is the same as the edge of the rear cover body 10 in the first direction A, i.e., when the cantilever 20 extends perpendicularly to the first direction A, the width of the cantilever 20 in the first direction A can be increased to ensure that at least a portion of the cantilever 20 is located outside the edge of the rear cover body 10 in the first direction A.

[0066] With at least a portion of the cantilever 20 positioned outside the edge of the rear cover body 10 in the first direction A, when the camera housing is located inside the cavity of the mounting component, the cantilever 20 ensures that the mounting portion 30 is located outside the cavity via the extended cantilever 20 and connected to the mounting structure of the vehicle body outside the cavity, thereby reducing the space required to accommodate the camera.

[0067] When the end of the camera housing without the cantilever 20 extends into the cavity of the vehicle body's component, the end of the camera housing with the cantilever 20 is fixed to the outside of the cavity of the vehicle body's component via the mounting part 30. Since the camera housing can be stably fixed by two opposing cantilever 20s connected to the mounting part 30, the number of cantilever 20s can be appropriately reduced.

[0068] Optionally, there are two cantilever arms 20, and the two cantilever arms 20 are respectively connected to the opposite ends of the same side of the rear cover body 10.

[0069] By setting the number of cantilever 20 to two and setting the two cantilever 20 opposite to each other, the purpose of the mounting structure that stably connects the camera housing to the vehicle body through the mounting part 30 can be achieved; at the same time, by reducing the number of cantilever 20, on the one hand, the manufacturing cost is reduced, and on the other hand, the space occupied by the mounting cantilever 20 and the mounting part 30 is reduced.

[0070] The vehicle body mounting housing may have an asymmetrical structure. To accommodate the asymmetrical structure of the vehicle body mounting housing cavity, optionally, at least two cantilever arms 20 may have different extension lengths; and / or, at least two cantilever arms 20 may have different shapes.

[0071] Each cantilever 20 can extend to different lengths; for example, the cantilever 20 can extend to different lengths in the first direction A, thereby enabling the mounting portion 30 to connect to the vehicle body mounting structure at different heights outside the vehicle body assembly. Each cantilever 20 can also extend along different directions or have different extension lengths in each direction. In other cases, the cantilever 20 can be configured with different shapes; for example, the cantilever 20 can be configured with different widths in the first direction A, and the mounting portion 30 can be located at the end of the cantilever 20 away from the rear cover body 10.

[0072] By setting different extension lengths and shapes for each cantilever, the mounting part 30 can be positioned at different heights outside the vehicle body's component, thereby adapting to the asymmetrical mounting structure of the vehicle body's component cavity.

[0073] Optionally, the cantilever 20 is plate-shaped, and the thickness of the cantilever 20 is between 1.5 mm and 2 mm.

[0074] When the cantilever 20 is plate-shaped, the plate-shaped cantilever 20 has a certain thickness. In the vehicle camera rear cover 100 according to an embodiment of this application, the thickness direction of the cantilever 20 is perpendicular to the plane containing the first direction A and the second direction B. In other embodiments, the thickness of the cantilever 20 may extend along other directions. The thickness of the cantilever 20 may be set between 1.5 mm and 2 mm.

[0075] By setting the thickness of the cantilever 20 between 1.5mm and 2mm, the mechanical strength of the cantilever 20 can be guaranteed, while achieving a lightweight design.

[0076] To further enhance the mechanical strength of the cantilever 20, reinforcing structures such as reinforcing plates and reinforcing ribs can be installed at the cantilever 20.

[0077] Optionally, the vehicle camera rear cover 100 also includes a reinforcing structure 40, which includes a reinforcing plate 41 and a reinforcing member 42. The reinforcing plate 41 is located between the cantilever 20 and the mounting part 30, and both sides of the reinforcing plate 41 are connected to the cantilever 20 and the mounting part 30 respectively. The reinforcing plate 41 is at a certain angle to the cantilever 20 to reinforce the cantilever 20. The reinforcing member 42 is connected to the reinforcing plate 41 and the cantilever 20 respectively.

[0078] like Figure 2 As shown, in the vehicle camera rear cover 100 according to an embodiment of this application, the reinforcing plate 41 is located between the cantilever 20 and the mounting portion 30. The mounting portion 30 and the cantilever 20 are respectively connected to both sides of the reinforcing plate 41, and both are perpendicular to the reinforcing plate 41, thereby providing support and reinforcement for the cantilever 20. In other embodiments, the mounting portion 30 and the cantilever 20 may form other angles with the reinforcing plate 41, which are not limited here.

[0079] The reinforcing member 42 connects the reinforcing plate 41 and the cantilever 20 to further enhance the mechanical strength of the cantilever 20. In some possible camera back cover structures according to embodiments of this application, the reinforcing member 42 is a "T"-shaped or triangular plate structure. The two perpendicular sides of the "T"-shaped reinforcing member 42 are connected to the perpendicular reinforcing plate 41 and the cantilever 20, respectively. The two right-angled sides of the triangular reinforcing member 42 are connected to the perpendicular reinforcing plate 41 and the cantilever 20, respectively. In other embodiments, the reinforcing member 42 may also be of other shapes. The thickness of the reinforcing member 42 can be selected according to actual conditions; for example, the thickness of the triangular reinforcing member 42 can be set to 0.7 mm.

[0080] By setting the reinforcing plate 41 and the reinforcing member 42, the mechanical strength of the cantilever 20 can be improved while maintaining the thickness of the cantilever 20.

[0081] The rear cover body 10 can be a plate-like structure or a cavity that can accommodate a vehicle camera. Figure 3 This is a schematic diagram of the structure of the vehicle camera rear cover 100 according to an embodiment of this application, viewed from the direction of the cavity opening.

[0082] Optionally, the rear cover body 10 forms a receiving cavity with an opening at one end, the opening being configured to face the vehicle camera front cover so that the receiving cavity is closed when the vehicle camera front cover and the vehicle camera rear cover 100 are connected to each other.

[0083] All cantilever arms 20 are located on the side of the opening.

[0084] The rear cover body 10 is a receiving cavity with an opening at one end. In the vehicle camera rear cover 100 according to an embodiment of this application, the direction of the opening is perpendicular to the plane containing the first direction A and the second direction B, i.e., the thickness direction of the rear cover body 10. In other embodiments, the direction of the opening may also be along other directions. The opening faces the front cover of the vehicle camera, and the vehicle camera front cover and the vehicle camera rear cover 100 are connected to form a cavity for receiving the camera. When the rear cover body 10 surrounds the receiving cavity with the opening, each cantilever 20 extends outward from the side of the opening of the rear cover body 10.

[0085] By configuring the rear cover body 10 with a receiving cavity, the rear cover body 10 has a more three-dimensional shape, thus providing support in multiple directions and higher mechanical strength. At the same time, compared with a plate-like structure, the receiving cavity with an opening can provide better housing space for the vehicle camera rear cover 100.

[0086] Specifically, the back cover body 10 includes a flat plate portion 12 and a casing 13. The casing 13 surrounds the periphery of the flat plate portion 12, and an opening is formed on the periphery edge of the casing 13 away from the flat plate portion 12. The first direction A and the second direction B are both located in the plane where the flat plate portion 12 is located.

[0087] Specifically, the receiving cavity of the rear cover body 10 is formed by the flat plate portion 12 and the surrounding shell 13 surrounding the flat plate portion 12, and the opening is formed on the side of the surrounding shell 13 away from the flat plate.

[0088] The front cover and rear cover 100 of the vehicle camera can be connected by means of clips, mounting holes, etc. When the front cover and rear cover 100 of the vehicle camera are connected by mounting holes, the mounting holes can be set in the main body 10 of the rear cover.

[0089] Optional, such as Figure 2 As shown, the rear cover body 10 is provided with a first mounting hole 11, which is configured to allow a first fastener to pass through the first mounting hole 11 so as to connect the rear cover body 10 and the vehicle camera front cover through the first fastener.

[0090] The rear cover body 10 may be provided with a plurality of first mounting holes 11. For example, in the vehicle camera rear cover 100 according to an embodiment of the present application, four first mounting holes 11 are provided at the corners of the rear cover body 10. In other embodiments, the number and position of the first mounting holes 11 may be adjusted according to actual conditions.

[0091] The first fastener can be a screw or bolt or other connecting component. The first fastener is usually connected to a stud, nut insert or other structure provided on the front cover of the vehicle camera, and is used to pass through the first mounting hole 11 to tightly connect the rear cover of the vehicle camera rear cover 100 with the front cover of the vehicle camera.

[0092] By providing a first mounting hole 11 in the rear cover body 10, fasteners can be used to connect the vehicle camera front cover to the vehicle camera front cover, making the connection between the two strong and reliable, while also facilitating disassembly.

[0093] Specifically, such as Figure 2 and Figure 3 As shown, the back cover body 10 is square, and a recessed portion 14 is provided at the corner of the back cover body 10. The recessed portion 14 is provided on one side of the thickness direction of the back cover body 10 and recessed to the other side of the thickness direction of the back cover body 10. The recessed portion 14 has a mounting surface facing the thickness direction of the back cover body 10, and a first mounting hole 11 is provided on the mounting surface.

[0094] The thickness direction of the back cover body 10 is perpendicular to the plane containing the first direction A and the second direction B. Along the thickness direction of the back cover body 10, a corner of the back cover body 10 is recessed from one side of the flat plate portion 12 toward the opening side, thereby forming a recessed portion 14. The recessed portion 14 has a mounting surface extending from one side of the back cover body 10 along its thickness direction to the other side, for providing a first mounting hole 11 thereon.

[0095] By placing the mounting holes at the corners of the square rear cover body 10, the connection between the rear cover body 10 and the vehicle camera front cover is made more stable. Furthermore, the recessed portion 14 allows the flat portion 12 of the rear cover body 10 to avoid the first fastener, thereby providing installation space for the first fastener connecting the vehicle camera front cover and the rear cover body 10. Through these design features, the structural strength of the rear cover body 10 is ensured, installation space is saved, and interference between components during installation is avoided.

[0096] Optional, such as Figure 2 and Figure 3As shown, the flat panel 12 has a first groove 121 on the side opposite to the opening. The first groove 121 is recessed towards the side of the rear cover body 10 that has an opening and has an opening 1211. The opening 1211 connects the interior and exterior of the receiving cavity. The first groove 121 is used to receive the infrared cover plate of the vehicle camera. Furthermore, the first groove 121 has a cylindrical second groove 1212. The second groove 1212 is recessed towards the side of the rear cover body 10 that has an opening. The second groove 1212 is used to receive the connector of the vehicle camera.

[0097] By providing the first groove 121 and the second groove 1212, space is provided for the infrared cover plate of the DMS camera and the corresponding connector.

[0098] The mounting part 30 can be connected to the mounting structure of the vehicle body by means of mounting holes or clips.

[0099] Optionally, the mounting part 30 is a mounting plate 31, on which a second mounting hole 311 is provided. The second mounting hole 311 is configured to allow a second fastener to pass through the second mounting hole 311, so as to connect the mounting structure of the vehicle camera rear cover 100 and the vehicle body through the second fastener. The axial direction of the second mounting hole 311 and the axial direction of the first mounting hole 11 have an included angle.

[0100] Mounting plate 31 is typically located at the end of cantilever 20, providing a relatively flat and spacious mounting interface for mounting part 30 and vehicle body mounting structure. Each mounting plate 31 may have one or more second mounting holes 311. The second fastener, similar to the first fastener, can be a screw or bolt, and connects to studs, nuts, or other structures on the vehicle body mounting structure. It passes through the second mounting holes 311 and tightly engages the vehicle camera rear cover 100 with the vehicle body mounting structure. Since the axis of the second mounting hole 311 is the same as the optical axis of the camera, there is an angle between the axis of the second mounting hole 311 and the axis of the first mounting hole 11, i.e., an angle between the axis of the second mounting hole 311 and the optical axis of the camera.

[0101] With the above settings, the camera housing can be inserted into the cavity of the vehicle body component at a certain angle, and the connecting parts between the vehicle camera rear cover 100 and the vehicle body component can be set outside the cavity, thereby reducing the space occupied by the camera housing inside the cavity of the vehicle body component.

[0102] In the vehicle camera rear cover 100 according to an embodiment of this application, the planes containing the two mounting plates 31 are parallel, and the axial direction of the second mounting hole 311 is at a certain angle to the axial direction of the first mounting hole 11, so as to facilitate the connection of the second fastener to the mounting structure on the vehicle body. For example, the angle can be 115 degrees. Then, when the camera housing is inserted into the cavity at an angle of 75 degrees to the outer edge of the cavity of the vehicle body fitting, the mounting plate 31 can fix the camera rear cover to the vehicle body fitting parallel to the outer edge of the cavity of the vehicle body fitting. In other possible camera rear cover structures, the vehicle camera rear cover 100 may also include other numbers of mounting plates 31, and to adapt to the asymmetrical mounting structure of the vehicle body fitting cavity, the mounting plates 31 may not be parallel to each other.

[0103] By setting the mounting part 30 as the mounting plate 31, and setting the axial direction of the second mounting hole 311 on the mounting plate 31 to have a certain angle with the axial direction of the first mounting hole 11, the camera housing can be inserted into the cavity of the vehicle body fitting at a certain angle, and the connecting part between the vehicle camera rear cover 100 and the vehicle body fitting is set outside the cavity, thereby reducing the space occupied by the camera housing inside the cavity of the vehicle body fitting.

[0104] When connecting the vehicle camera rear cover 100 to the vehicle body mounting structure via the mounting holes, the second fastener needs to be installed through the second mounting hole 311 and attached to the corresponding studs or other connecting structures on the vehicle body, making the entire installation process rather cumbersome. To facilitate the installation and removal of the camera housing, a snap-fit ​​connection can also be used to connect the vehicle camera rear cover 100 to the vehicle body mounting structure.

[0105] Optional, such as Figure 4 The diagram shown is a structural schematic of another vehicle camera rear cover 100 according to an embodiment of this application.

[0106] The mounting part 30 is a mounting clip 32, which is used to engage with the mounting structure of the vehicle body.

[0107] The mounting buckle 32 can be provided in the form of a protrusion at the end of the cantilever 20 away from the rear cover body 10, and a corresponding slot can be provided on the outside of the cavity of the hand component on the vehicle body so that the mounting buckle 32 can be directly inserted into the slot and the vehicle camera rear cover 100 can be fixed.

[0108] By setting the mounting part 30 as the mounting buckle 32, it is easy to install and remove the camera back cover, while the mounting part 30 and the vehicle body mounting structure occupy less space.

[0109] like Figure 5 The image shows a camera module 200 according to an example of this application, comprising:

[0110] Camera body (not shown);

[0111] The camera housing includes a front cover 110 for the vehicle camera and a rear cover 100 for the vehicle camera. The front cover and the rear cover together form a receiving cavity, in which the camera body is disposed.

[0112] The camera module in this embodiment uses the aforementioned vehicle camera rear cover 100. Since the aforementioned vehicle camera rear cover 100 can accommodate the camera housing at a certain angle inside the limited space cavity of the vehicle body, and fix the camera housing outside the cavity, the camera module according to the embodiment of this application can install the camera inside the limited space cavity of the vehicle body.

[0113] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
