Description

Technical Field

[0001] This application relates to the field of sensor mounting technology, and more particularly to a mounting bracket, a bumper assembly, and a vehicle. Background Technology

[0002] The bumper is a component of the car's structure and also integrates a reversing radar function. For example, the reversing radar sensor can be glued or welded to the front or rear bumper using mounting brackets.

[0003] In related technologies, sensor mounting brackets include concealed mounting brackets and exposed mounting brackets. Concealed mounting brackets refer to sensors embedded inside the bumper, fixed to the inner surface of the bumper by adhesive or welding, making the sensor's detection surface flush with the outer surface of the bumper. Exposed mounting brackets allow for a certain angular deviation between the sensor and the bumper surface through an exposed bracket structure that transitions from the bumper surface to the sensor plane.

[0004] However, concealed mounting brackets require a smooth bumper surface, while exposed mounting brackets occupy a large amount of space and have limited compatibility with sensors, making it impossible to effectively install sensors on complex curved surfaces (such as V-shapes). Utility Model Content

[0005] This application provides a mounting bracket, a bumper assembly, and a vehicle that enables the mounting of sensors on the complex curved surface of the bumper.

[0006] To achieve the above objectives, the technical solution of this application is as follows:

[0007] In a first aspect, this application provides a mounting bracket, comprising: a bracket body, the bracket body being bent for connection with a bumper, the bracket body having a protrusion and a notch, at least a portion of the notch extending to one side of the protrusion, the protrusion being used to mount a sensor, the notch being located on one side of the sensor's connector, and the notch being used to expose a portion of the bumper.

[0008] In one possible implementation, the mounting bracket provided in this application embodiment includes a first body and a second body. The first body is connected to the second body. The first body has a protrusion with a mounting hole. The second body is disposed around the periphery of the mounting hole and extends inward from the top of the protrusion. The first body is bent to be connected to the bumper, and the second body is connected to the sensor.

[0009] In one possible implementation, the mounting bracket provided in this application embodiment has a snap-fit ​​groove on the extended end of the second body for connecting with a connector, and the gap between the connector and the bumper located at the notch is less than or equal to 3mm.

[0010] In one possible implementation, the mounting bracket provided in this application embodiment has an extension depth of the extension end in a ratio of 3:1 to the width of the extension end to the inner wall of the protrusion; the distance from the outer side of the protrusion to the inner side of the adjacent extension end is greater than or equal to 12.5 mm.

[0011] In one possible implementation, the mounting bracket provided in this application embodiment includes a first connecting part, a second connecting part, and a third connecting part connected in sequence. The first connecting part and the third connecting part are both inclined, and the second connecting part is bent so that the first connecting part and the third connecting part are both in contact with the inner surface of the bumper.

[0012] In one possible implementation, the mounting bracket provided in this application embodiment further includes an adhesive portion, at least a portion of which is disposed on at least one of the first connecting portion and the third connecting portion.

[0013] In one possible implementation, the mounting bracket provided in this application embodiment further includes at least one limiting step, which is disposed on the outside of the protrusion and around the periphery of the mounting hole.

[0014] In one possible implementation, the mounting bracket provided in this application embodiment has multiple limiting steps, which are arranged around the periphery of the mounting hole.

[0015] Secondly, this application provides a bumper assembly, including: a bumper and a mounting bracket of any of the above embodiments disposed on the bumper, the bumper having a bulge, and the protrusion of the mounting bracket being embedded in the bulge.

[0016] In one possible implementation, the bumper assembly provided in this application embodiment further includes a sensor with a connector, the sensor being mounted inside the bump via a protrusion, and the connector portion extending to a notch.

[0017] Thirdly, this application also provides a vehicle including: a bumper assembly according to any of the above embodiments.

[0018] This application provides a mounting bracket, a bumper assembly, and a vehicle. The mounting bracket includes a bracket body bent to connect with the bumper. The bracket body has a protrusion and a notch, with at least a portion of the notch extending to one side of the protrusion. The protrusion is used to mount a sensor, and the notch is located on one side of the sensor's connector, exposing a portion of the bumper. This application solves the sensor's dependence on the bumper's smoothness by bending the bracket body to adapt to the complex curved surface (V-shape) of the bumper, such as by fitting the bracket body against the inner V-shaped surface of the bumper. The bumper has a bulge, and the protrusion of the bracket body matches the bulge on the V-shaped bumper, thus providing installation space for the sensor. One end of the sensor passes through the protrusion and the bulge, allowing the sensor's detection surface to smoothly transition with the outer surface of the bumper. This avoids a decrease in detection performance caused by changes in surface curvature. The notch, while ensuring the sensor's detection performance, reduces the overlap area between the bracket body and the bumper, shrinks the size of the bumper, and thus reduces the volume of the bracket body. This minimizes the sensor's installation space requirements and reduces restrictions on the bumper's shape. Therefore, this application enables the installation of a sensor on the complex curved surface of the bumper. Attached Figure Description

[0040] In automotive structures, bumpers are not only important structural components that protect the vehicle body, but also serve as carriers for integrating various functional modules, such as reversing radar sensors, forward radar, and cameras.

[0041] As car designs become more diverse, the surface structure of bumpers is becoming increasingly complex, including non-smooth areas such as V-shaped surfaces and multi-directional curved surfaces. These complex surfaces present challenges for sensor installation. On one hand, the sensor's detection performance requires its surface to be aligned with the bumper's outer surface (i.e., the sensor's detection surface must strictly match the normal direction of the bumper surface) to ensure the accuracy of the detection angle and range. On the other hand, the geometric characteristics of complex surfaces (such as drastic curvature changes and a lack of smooth areas) make it difficult to find suitable installation locations using traditional methods.

[0042] In related technologies, the sensor 20 is installed in two ways: a concealed mounting bracket 30 and an exposed mounting bracket 40. The concealed mounting bracket 30 embeds the sensor 20 inside the bumper 10, and it is fixed to the inner surface of the bumper 10 by adhesive or welding, ensuring that the detection surface of the sensor 20 is completely flush with the outer surface of the bumper 10. Figure 11 As shown. The concealed mounting bracket 30 has an aesthetically pleasing appearance and, being invisible, has no significant impact on the shape of the bumper 10. However, it requires a high degree of smoothness on the surface of the bumper 10, necessitating sufficient space in the mounting area to accommodate the installation angle of the sensor 20 and the bracket. However, in complex curved areas such as V-shapes, this solution is difficult to implement due to the lack of smooth surfaces.

[0043] like Figure 12As shown, the exposed mounting bracket 40 transitions from the surface of the bumper 10 to the plane of the sensor 20 through the exposed bracket structure, allowing for a certain angular deviation between the sensor 20 and the surface of the bumper 10. This solution compensates for the angular difference by adjusting the geometry of the bracket. However, since the exposed bracket requires additional body paint spraying, it increases manufacturing costs and necessitates additional drilling processes (such as punching or laser cutting). Furthermore, it has strict limitations on the angle (usually within the range of 70°-110°), resulting in a limited range of compatibility between the bracket and the sensor 20. In addition, this solution has a poor appearance and is prone to visual interference.

[0044] For example, in the V-shaped bumper 10 area, due to the large curvature changes in both the Y and Z directions, traditional mounting brackets cannot achieve the matching of sensor 20 and bumper 10 through simple plane fitting or angle adjustment. Moreover, the installation process relies on high-precision mold opening or welding processes, which further increases manufacturing costs and design complexity.

[0045] Both of the above methods have different requirements. The hidden mounting bracket 30 requires a smooth surface on the bumper 10, while the exposed mounting bracket 40 occupies a large space and has a limited range of compatibility with the sensor 20. Neither can effectively install the sensor 20 on complex curved surfaces (such as V-shapes), making it difficult to adapt to the conformal fitting requirements of complex curved surfaces. In addition, it also greatly restricts the freedom of design of the bumper 10.

[0046] In view of this, this application provides a mounting bracket, a bumper assembly, and a vehicle. The mounting bracket includes a bracket body bent to connect with the bumper. The bracket body has a protrusion and a notch, with at least a portion of the notch extending to one side of the protrusion. The protrusion is used to mount a sensor, and the notch is located on one side of the sensor's connector, exposing a portion of the bumper. This application, by bending the bracket body to adapt to the complex curved surface (V-shape) of the bumper, such as by fitting the bracket body against the inner V-shaped surface of the bumper, solves the sensor's dependence on the bumper's smoothness, making the bumper's complex curved surface a suitable mounting location. The bumper has a bulge, and the protrusion of the bracket body matches the bulge on the V-shaped bumper, thus providing installation space for the sensor. One end of the sensor passes through the protrusion and the bulge, allowing the sensor's detection surface to smoothly transition with the outer surface of the bumper. This avoids a decrease in detection performance caused by changes in surface curvature. The notch, while ensuring the sensor's detection performance, reduces the overlap area between the bracket body and the bumper, shrinks the size of the bumper, and thus reduces the volume of the bracket body. This minimizes the sensor's installation space requirements and reduces restrictions on the bumper's shape. Therefore, this application enables the installation of a sensor on the complex curved surface of the bumper.

[0047] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0048] This application provides a mounting bracket, combined with Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 The device includes: a bracket body 100, which is bent to connect to a bumper 10. The bracket body 100 has a protrusion 101 and a notch 102, at least part of which extends to one side of the protrusion 101. The protrusion 101 is used to mount a sensor 20. The notch 102 is located on one side of the connector 21 of the sensor 20 and is used to expose part of the bumper 10.

[0049] Combination Figure 3 and Figure 4 The bracket body 100 is used to connect and fix the sensor 20 to the bumper 10. The bracket body 100 has a bending structure to adapt to the curved surface of the bumper 10. The bending refers to the non-planar geometry of the bracket body 100, which forms a structure that adapts to the surface of the bumper 10 through multiple bending segments.

[0050] The bracket body 100 conforms to the V-shaped inner surface of the bumper 10 through a bending structure, and is fitted with the bumper 10 bulge through the protrusion 101, providing installation space for the sensor 20. V-shaped, arc-shaped, or multi-segment bending structures are used to conform to the complex curved surface of the bumper 10.

[0051] The protrusion 101 refers to the outwardly extending structural portion on the bracket body 100, used to support the sensor 20 and provide installation space. It can be columnar, block-shaped, or an irregularly shaped structure adapted to the bumper 10 bulge 11. In this application, a bulge 11 is provided on the complex curved surface (such as V-shape) of the bumper 10, and the protrusion 101 fits into the bulge 11.

[0052] Notch 102 refers to a partially missing area on the bracket body 100, used to expose a portion of the bumper 10 to accommodate the sensor 20 connector 21. It can be regular or irregular in shape, extending to one side of the protrusion 101 or covering the entire area on the side of the connector 21.

[0053] For example, a notch 102 is provided on the bracket body 100, extending to one side of the protrusion 101, to expose a partial area of ​​the bumper 10, so that the gap between the connector 21 and the bumper 10 only needs to meet the minimum safety range. By exposing a partial area of ​​the bumper 10, the notch 102 reduces the overlap space requirement between the bracket body 100 and the bumper 10. In related technologies, a large space needs to be reserved on one side of the connector 21 to meet the bracket material thickness (e.g., 2mm) and safety range requirements (e.g., 3mm), while the embodiment of this application directly exposes part of the bumper 10, so that the gap between the connector 21 and the bumper 10 only needs to meet the minimum safety range (e.g., 3mm), without considering the bracket material thickness limitation.

[0054] Furthermore, the irregular shape design of the notch 102 (such as extending to one side of the protrusion 101) further optimizes the spatial distribution, minimizing the size of the bumper 11 and thus reducing the constraints on the shape of the bumper 10.

[0055] Meanwhile, the fit between the notch 102 and the connector 21 avoids installation interference caused by insufficient space in the connector 21, ensuring that the detection performance of the sensor 20 is not affected. This application achieves a balance between minimizing the space requirement of the sensor 20 and its detection performance through structural optimization, solving the problem of low space utilization of traditional mounting brackets in complex curved areas.

[0056] Connector 21 refers to the part of sensor 20 that connects to external circuits or interfaces. It is usually a pin, plug, or wire interface, and can be cylindrical, rectangular, or other standardized interface forms.

[0057] This application utilizes a bent bracket body 100 to adapt to the surface of the bumper 10 and its complex curved surfaces, such as the bracket body 100 fitting against the inner surface of a V-shape. This solves the sensor 20's dependence on the smoothness of the bumper 10, making the V-shape a suitable mounting position. The bumper 10 has a bulge 11, and the protrusion 101 of the bracket body 100 adapts to the bulge 11 on the V-shaped bumper 10, thus providing mounting space for the sensor 20. This allows one end of the sensor 20 to pass through the protrusion 101 and the bulge 11, ensuring a smooth transition between the sensor 20's detection surface and the outer surface of the bumper 10. This avoids performance degradation caused by changes in surface curvature. Furthermore, the notch 102, while maintaining the sensor 20's detection performance, reduces the volume of the bracket body 100 and the bulge structure of the bumper 10, minimizing the sensor 20's mounting space requirements and reducing restrictions on the bumper 10's shape.

[0058] The bracket body 100 includes a first body 110 and a second body 120. The first body 110 is connected to the second body 120. The first body 110 has a protrusion 101 and a notch 102. The protrusion 101 has a mounting hole 103. The second body 120 is arranged around the periphery of the mounting hole 103 and extends inward from the top of the protrusion 101. The first body 110 is bent to connect with the bumper 10, and the second body 120 is connected with the sensor 20.

[0059] The first body 110 refers to a part of the bracket body 100, which is used to connect with the bumper 10 and support the protrusion 101. It may be a V-shaped structure and includes a first connecting part 111, a second connecting part 112 and a third connecting part 113.

[0060] The second body 120 refers to another part of the bracket body 100, which is used to connect with the sensor 20 and is arranged around the mounting hole 103. It can be an annular or arc-shaped structure and extends into the protrusion 101 to fix the sensor 20. The mounting hole 103 refers to the through hole on the protrusion 101 for accommodating the sensor 20. It can be circular, rectangular or other holes adapted to the shape of the sensor 20.

[0061] The first body 110 is attached to the inner surface of the bumper 10 via a bending structure and is fixed by an adhesive part 130. The second body 120 is arranged around the mounting hole 103 of the protrusion 101 and extends into the protrusion 101, so that the sensor 20 is embedded in the protrusion 101 through the mounting hole 103. The extended end of the second body 120 is connected to the sensor 20 and fixed by a snap-fit ​​groove 121 or a threaded structure. The connection between the first body 110 and the second body 120 is achieved by welding, snap-fit, or screws, or the first body 110 and the second body 120 are integrally formed.

[0062] In some embodiments, the extended end of the second body 120 has a snap-fit ​​groove 121 for connecting with the connector 21, and the gap between the connector 21 and the bumper 10 located in the notch 102 is less than or equal to 3 mm.

[0063] The extension end refers to the portion of the second body 120 that extends inward toward the protrusion 101. It can be a columnar or plate-like structure, extending along the inner side of the mounting hole 103. The snap-fit ​​groove 121 refers to the recessed structure on the extension end for snapping with the connector 21. It can be rectangular, trapezoidal, or other grooves adapted to the shape of the connector 21. The extension end of the second body 120 extends inward toward the protrusion 101, and the snap-fit ​​groove 121 is provided at the extension end.

[0064] The sensor 20 connector 21 is fixed to the extension end via a snap-fit ​​groove 121. The shape of the snap-fit ​​groove 121 matches the connector 21, and the connection is achieved through a snap or elastic structure. This design allows the connector 21 to be embedded inside the bumper 10 bulge, reducing external exposure, while the limiting effect of the snap-fit ​​groove 121 prevents the connector 21 from falling off due to vibration or external force.

[0065] It is understood that the notch 102 is provided on the first body 110, and at least part of the notch 102 extends to one side of the protrusion 101. The gap w between the position of the sensor 20 connector 21 and the bumper 10 is less than or equal to 3mm. There is no need to consider the basic material thickness of the mounting bracket, that is, the thickness of the first body 110 is usually 2mm.

[0066] The notch 102 is positioned opposite to the slot 121. It should be noted that this application does not limit the formation of the notch 102, and the notch 102 can be an irregular shape.

[0067] The protrusion 101 has two opposing sides, with a partial notch 102 extending to one side and the other side being a closed surface, which is spaced from the outer side of the adjacent extension end.

[0068] In some embodiments, such as Figure 5 As shown, the ratio of the depth of the extension end to the width of the extension end to the inner wall of the protrusion 101 is 3:1.

[0069] To meet the basic requirements of plastic injection molds, the closed surface and the outer side of the adjacent extension end are spaced apart, and the ratio of the depth of the space to the width of the extension end is 3:1.

[0070] The extension depth refers to the length by which the extension end extends inward toward the protrusion 101. The design of the extension depth to width ratio of the extension end meets the demolding requirements of the plastic injection mold. The 3:1 ratio of extension depth to width ensures that the extension end is easy to demold during injection molding, while avoiding insufficient structural strength due to disproportionate ratio.

[0071] In some embodiments, such as Figure 5 As shown, the distance from the inner side of the extension end along the first direction to the outer surface of the adjacent bulge 11 is greater than or equal to 12.5 mm.

[0072] The distance from the outer side of the protrusion 101 to the adjacent extension end to the adjacent inner side is greater than or equal to 12.5 mm, such as... Figure 5 W1 in the middle. The distance from the inner side of the extension end along the first direction to the outer surface of the adjacent bulge 11 is greater than or equal to 12.5mm. The first direction is the z direction. Since the bulge 11 is in the V structure, the space of the bulge 11 in the Z direction is insufficient. Therefore, in order to ensure the installation requirements of the sensor 20, a spacing requirement is set in the space of the Z direction.

[0073] In some embodiments, combined with Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 10 The first body 110 includes a first connecting part 111, a second connecting part 112 and a third connecting part 113 connected in sequence. The first connecting part 111 and the third connecting part 113 are both inclined. The second connecting part 112 is bent to form a rounded corner so that the first connecting part 111 and the third connecting part 113 are both in contact with the inner surface of the bumper 10.

[0074] Both the first connecting part 111 and the third connecting part 113 are inclined. The extension direction of the first connecting part 111 intersects the extension direction of the third connecting part 113. The second connecting part 112 is bent to form a rounded corner. The two ends of the second connecting part 112 are the first connecting part 111 and the third connecting part 113, respectively.

[0075] The first body 110 includes a first connecting part 111, a second connecting part 112 (bent to form rounded corners) and a third connecting part 113 connected in sequence, and has an overall V-shaped bending structure that fits the V-shaped inner surface of the bumper 10.

[0076] In some embodiments, combined with Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 10 This application also includes an adhesive portion 130, at least a portion of which is disposed on at least one of the first connecting portion 111 and the third connecting portion 113. The mounting bracket is bonded to the inner surface of the bumper 10 via the adhesive portion 130.

[0077] For example, the adhesive portion 130 may be provided only on the inner surface of the first connecting portion 111 facing the bumper 10, or the adhesive portion 130 may be provided only on the inner surface of the third connecting portion 113 facing the bumper 10, or the adhesive portion 130 may be provided on both the first connecting portion 111 and the third connecting portion 113.

[0078] The adhesive portion 130 is not provided on the second connecting portion 112, or the adhesive portion 130 is partially provided on the second connecting portion 112. Since the bottom of the V-shaped bumper 10 is rounded, the second connecting portion 112 is adapted to the bottom of the V-shaped bumper 10. The adhesive portion 130 includes two adhesive segments, with adjacent adhesive segments spaced apart at the corners of the first body 110.

[0079] During installation, the first body 110 of the bracket body 100 conforms to the V-shaped inner surface of the bumper 10 through a V-shaped bending structure, and the adhesive part 130 is fixed to the inner side of the bumper 10 with adhesive. The sensor 20 body is embedded into the protrusion 101 through the mounting hole 103 and fixed to the connector 21 through the snap-fit ​​groove 121 of the second body 120. The notch 102 design exposes a partial area of ​​the bumper 10 on the side of the connector 21, reducing the overlap space requirement between the bracket body 100 and the bumper 10. The protrusion 101 fits into the bumper 11 of the bumper 10, so that the detection surface of the sensor 20 smoothly transitions from the outer surface of the protrusion 101 to the outer surface of the bumper 10, avoiding the decrease in detection performance caused by curvature changes.

[0080] In some embodiments, combined with Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 The application also includes at least one limiting step 122, which is disposed on the outside of the protrusion 101 and around the periphery of the mounting hole 103.

[0081] Because the bump 11 has a first connecting hole with an arc-shaped inner wall, the positioning between the bracket and the inner surface of the bump 11 is not easy to fit, which will result in poor matching between the appearance of the sensor 20 and the outer surface of the bumper 10.

[0082] Therefore, a limiting step 122 is provided on the outer side of the protrusion 101 and distributed around the mounting hole 103 to compensate for the local gap between the bracket and the inner surface of the bumper 11 of the bumper 10, so that the surface of the sensor 20 is consistent with the surface of the bumper 10.

[0083] This application does not limit the number of limiting steps 122; for example, the number of limiting steps 122 may be one or more. When there are multiple limiting steps 122, each limiting step 122 is spaced apart along the periphery of the mounting hole 103. The protruding structure of the limiting step 122 and the contact surface of the bracket form a fine-tuning space, and the installation error caused by the change of curvature of the curved surface is compensated by adjusting the height of the step.

[0084] The limiting step 122 is a raised structure distributed around the mounting hole 103, which absorbs the local gap between the bracket and the inner surface of the bumper 10 bulge 11 during installation.

[0085] In some embodiments, the inner wall of the bumper 10 bulge 11 is an arc surface. The positioning of the bracket and the inner surface of the bulge 11 is prone to misalignment between the sensor 20 detection surface and the outer surface of the bumper 10 due to the difference in curvature, thereby affecting the detection performance. However, in the embodiments of this application, the fine-tuning effect of the limiting step 122 compensates for the installation error caused by the curvature change, so that the sensor 20 detection surface and the outer surface of the bumper 10 maintain a smooth transition.

[0086] Specifically, this application solves the problem in related technologies where mounting brackets cannot adapt to complex curved surfaces by fitting the bent bracket body 100 to the V-shaped inner surface of the bumper 10, making the V-shape a usable mounting position. The notch 102 reduces the installation space requirement on the side of the sensor 20 connector 21, and combined with the optimized ratio of the extension end to the depth (1:3), the size of the bulge 11 is reduced, improving space utilization. The fitting of the protrusion 101 and the bulge 11 allows for a smooth transition between the sensor 20 detection surface and the outer surface of the bumper 10, avoiding a decrease in detection performance due to curvature changes. In addition, the bending of the bracket body 100 does not require additional drilling or welding processes, reducing manufacturing costs. At the same time, the bracket of this application is a hidden installation, making the overall appearance of the bumper 10 harmonious and eliminating the need for additional painting. Therefore, this application achieves reliable installation of the sensor 20 in complex curved surface areas, while taking into account detection performance, styling freedom, and cost control.

[0087] In some embodiments, combined with Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 This application also provides a bumper assembly, including: a bumper 10 and a mounting bracket of any of the above embodiments disposed on the bumper 10, the bumper 10 having a bulge 11, and the protrusion 101 of the mounting bracket being embedded in the bulge 11.

[0088] Bumper assemblies are structural components used to buffer collisions at the front or rear of a car. They are usually made of plastic or composite materials. For example, bumper assemblies may have V-shaped, arc-shaped, or multi-directional curved surface structures with bulges 11 or openings to accommodate sensors 20.

[0089] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 The bumper 10 has a bulge 11 that is adapted to a protrusion 101 of a mounting bracket to accommodate the sensor 20 and the mounting bracket.

[0090] Using the plane of sensor 20 as a reference, a bulge 11 is formed on the plane of the V-shaped bumper 10. The bulge 11 protrudes outward toward the bumper 10 and is adapted to the protrusion 101 of the mounting bracket. The size of the bulge 11 is set according to the spatial structure on both sides of the bumper 10, and this application does not limit it. One side of the bulge 11 is used to accommodate the connector 21 of sensor 20.

[0091] This application does not limit the number of drums 11 to one or more, and can set it as needed, for example, two drums 11 can be set at intervals.

[0092] The bumper assembly may also include a sensor 20 having a connector 21, the sensor 20 being mounted within the bulge 11 via a protrusion 101, the connector 21 extending partially into a notch.

[0093] The sensor 20 is positioned at a suitable location on the bumper 10 to meet the radar's performance requirements, such as detection range and detection angle, while also considering the aesthetic appeal of the sensor 20 on the surface of the bumper 10. The sensor 20 is fixed to the bumper 10 by a mounting bracket, and the plane of the sensor 20 is flush with the outer surface of the bumper 10.

[0094] It should be noted that, in order to reduce the size of the bulge 11, the sensor 20 includes a body and a connector 21. The body is connected to the connector 21, and the extension direction of the body is perpendicular to the extension direction of the connector 21. That is, the change in the direction of the connector 21 reduces the lateral dimension (along the x-direction) of the bulge 11, and the lateral dimension of the corresponding protrusion 101 also decreases, minimizing the space requirement inside the bulge 11.

[0095] This application applies to complex curved surfaces (such as V-shapes) of automobile bumpers 10, such as the inner V-shaped surface of the front bumper 10 or the rear bumper 10, or shaped surfaces with multi-directional curvature.

[0096] It should be noted that the embodiments of this application are applicable to the installation of the reversing radar sensor 20, and can also be extended to scenarios that require fitting complex curved surfaces, such as cameras and forward radar.

[0097] This application also provides a vehicle, including: a bumper assembly according to any of the above embodiments. This application does not limit the structure of the vehicle; for example, the vehicle can be a gasoline vehicle, an electric vehicle, or a hybrid vehicle.

[0098] Other embodiments of this application will readily occur to those skilled in the art upon consideration of the specification and practice of the utility model disclosed herein. This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only.

[0099] It should be understood that this application is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope.
