Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle technology, and more particularly to a rear bumper assembly and a vehicle. Background Technology
[0002] Vehicles have become an indispensable means of transportation in people's daily lives. The rear bumper assembly is a core component at the rear of a vehicle, integrating safety protection, functional load-bearing, and styling design. The rear bumper assembly takes into account structural mechanical performance, intelligent function expansion, and user scenario-based needs.
[0003] The rear bumper requires the installation of various intelligent components. In related technologies, rear bumper assemblies often adopt a "modular" architecture. Intelligent modules such as cameras and Bluetooth modules are fixed to the sheet metal structure via separate mounting brackets. Then, the sheet metal structure connects the rear skirt sheet metal and the rear bumper sheet metal to form the rear bumper assembly. However, the production, processing, and assembly processes of the rear bumper assembly are relatively complex and costly. Utility Model Content
[0004] In view of this, embodiments of this application provide a rear bumper assembly and a vehicle. By integrating components, the integration of intelligent modules can be improved, thereby optimizing production, processing and assembly processes, and thus reducing production costs.
[0005] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:
[0006] In a first aspect, embodiments of this application provide a rear bumper assembly, which includes:
[0007] Tail skirt sheet metal;
[0008] An integrated component, comprising a plastic bracket, a first functional module, and a second functional module, wherein the plastic bracket is disposed on the rear side of the rear skirt sheet metal along the length direction of the vehicle, and the first functional module and the second functional module are directly connected to the plastic bracket respectively;
[0009] The rear bumper body is located along the length of the vehicle and is positioned behind the plastic bracket. The rear bumper body has mounting openings through which at least part of the first functional module and / or the second functional module can pass.
[0010] The rear bumper assembly provided in this application embodiment integrates a plastic bracket for a first functional module and a second functional module. The first and second functional modules can be directly connected to the plastic bracket. Therefore, the integration level of the rear bumper assembly can be improved. Specifically, direct connection means that the first and second functional modules do not need to be connected to the plastic bracket via their respective mounting brackets or other structures. This simplifies the structure, production, and assembly processes of the integrated component, improves the integration level of the rear bumper assembly, and helps reduce the production cost of the integrated component, thereby reducing the overall production cost of the rear bumper assembly.
[0011] It is easy to understand that when the first and second functional modules are fixed to the plastic bracket via mounting brackets, on the one hand, there are costs associated with the raw materials, processing, and maintenance of the mounting brackets; on the other hand, the mounting brackets need to be fixed to the plastic brackets using fasteners or other structures, which can easily complicate the assembly process and increase assembly costs. Therefore, in this embodiment, the first and second functional modules can be directly fixed to the plastic brackets, which helps to reduce the aforementioned costs and thus reduce the cost of the rear bumper assembly.
[0012] Furthermore, in this embodiment, the plastic bracket can be used to connect the rear skirt sheet metal and the rear bumper body. The plastic bracket can have a lighter weight, thereby reducing the weight of the rear bumper assembly, which is beneficial for achieving lightweight vehicle design and thus improving the range of electric vehicles.
[0013] In one possible implementation of this application, a limiting structure is provided on the surface of the rear bumper body facing the rear skirt sheet metal. The limiting structure is disposed on the outer periphery of the mounting opening. The limiting structure is used to connect with the first functional module when a portion of the first functional module passes through the mounting opening.
[0014] In one possible implementation of this application, the limiting structure includes a first limiting surface facing the center of the mounting opening, the first limiting surface being connected to the first functional module to constrain the gap between the outer peripheral sidewall of the first functional module and the inner wall of the mounting opening; and / or,
[0015] The limiting structure includes a second limiting surface facing the plastic bracket. The second limiting surface is connected to the first functional module to constrain the height of the first functional module protruding from the rear surface of the rear bumper body.
[0016] In one possible implementation of this application, the plastic bracket is provided with a snap-fit connector, and the second functional module is detachably connected to the plastic bracket via the snap-fit connector.
[0017] In one possible implementation of this application, the plastic bracket is provided with a support portion facing the tail skirt sheet metal, and the support portion abuts against the tail skirt sheet metal.
[0018] In one possible implementation of this application, one of the plastic bracket and the rear bumper body is provided with a limiting protrusion, and the other of the plastic bracket and the rear bumper body is provided with a limiting groove. The limiting protrusion and the limiting groove cooperate to at least fix the plastic bracket and the rear bumper body relative to each other along the width direction of the vehicle.
[0019] In one possible implementation of this application, one of the plastic bracket and the rear bumper body is provided with a snap-fit protrusion, and the other of the plastic bracket and the rear bumper body is provided with a snap-fit groove. The snap-fit protrusion and the snap-fit groove cooperate to at least fix the plastic bracket and the rear bumper body relative to each other along the length direction of the vehicle.
[0020] In one possible implementation of this application, one of the plastic bracket and the rear bumper body is provided with a plug-in portion, and the other of the plastic bracket and the rear bumper body is provided with a plug-in groove. The plug-in portion and the plug-in groove cooperate to at least limit the plastic bracket and the rear bumper body along the height direction of the vehicle.
[0021] In one possible implementation of this application, along the height direction of the vehicle, the plastic bracket has a support surface facing the rear bumper body, and the support surface is connected to the rear bumper body.
[0022] Secondly, embodiments of this application provide a vehicle that includes the rear bumper assembly of any of the above embodiments. Attached Figure Description

[0053] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.
[0054] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.
[0055] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.
[0056] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can mean a fixed connection, a detachable connection, or an integral part; it can mean a direct connection or an indirect connection through an intermediate medium.
[0057] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.
[0058] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.
[0059] This application provides a rear bumper assembly that can be applied to vehicles. The rear bumper assembly is a core component of the vehicle's rear end, integrating safety protection, functional load-bearing, and styling design.
[0060] It should be noted that the vehicle in this application can refer to large vehicles, small vehicles, special-purpose vehicles, etc. For example, according to vehicle type, the vehicle in this application can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles. Generally, a vehicle is equipped with wheels, a power source, and a transmission system between the wheels and the power source. The transmission system can transmit the power provided by the power source to the wheels, causing the wheels to rotate and thus driving the vehicle.
[0061] It should be noted that the type of power source of the vehicle is not limited in the embodiments of this application. For example, for fuel vehicles, the power source can refer to fuel engines such as gasoline engines and diesel engines; for electric vehicles, the power source can refer to electric motors; for hybrid vehicles, the power source can refer to engines or electric motors; for vehicles powered by other means, the power source can refer to devices that generate power.
[0062] The rear bumper assembly balances structural mechanics performance, intelligent function expansion, and user scenario-based needs. The rear bumper requires the installation of various intelligent components. In related technologies, intelligent modules such as cameras and Bluetooth modules are fixed to the sheet metal structure using separate mounting brackets. Then, the sheet metal structure connects the rear skirt sheet metal and the rear bumper sheet metal to form the rear bumper assembly. However, the production, processing, and assembly processes of the rear bumper assembly are relatively complex and costly.
[0063] The rear bumper assembly 100 provided in this application embodiment includes a plastic bracket 121 for connecting the rear skirt sheet metal 110 and the rear bumper body 130. The plastic bracket 121 can integrate at least two functional modules, thus simplifying processing, production, and assembly procedures, and helping to reduce the production cost of the rear bumper assembly 100. Furthermore, the plastic bracket 121 itself is lightweight, which helps to achieve weight reduction in the rear bumper assembly 100, thereby contributing to vehicle weight reduction.
[0064] Based on this, refer to Figures 1 to 3 This application provides a rear bumper assembly 100, which is applied to a vehicle. The rear bumper assembly 100 includes a rear skirt sheet metal 110, an integrated component 120, and a rear bumper body 130.
[0065] The integrated component 120 includes a plastic bracket 121, a first functional module 122, and a second functional module 123. Along the length X of the vehicle, the plastic bracket 121 is disposed on the rear side of the rear skirt sheet metal 110. The first functional module 122 and the second functional module 123 are directly connected to the plastic bracket 121.
[0066] Along the length direction X of the vehicle, the rear bumper body 130 is located on the rear side of the plastic bracket 121, and the rear bumper body 130 is provided with a mounting opening 130a through which at least part of the first functional module 122 and / or the second functional module 123 can pass.
[0067] It should be noted that, along the length X of the vehicle, the plastic bracket 121 being located behind the rear skirt sheet 110 can mean that the plastic bracket 121 is located on the side of the rear skirt sheet 110 closer to the rear of the vehicle. Similarly, the rear bumper body 130 being located behind the plastic bracket 121 can mean that the rear bumper body 130 is located on the side of the plastic bracket 121 closer to the rear of the vehicle. In other words, along the length X of the vehicle and from the front to the rear, the rear skirt sheet 110, the plastic bracket 121, and the rear bumper body 130 are arranged sequentially.
[0068] In this embodiment, the plastic bracket 121 of the integrated component 120 can be used to integrate the first functional module 122 and the second functional module 123. The first functional module 122 and the second functional module 123 can be directly connected to the plastic bracket 121. Therefore, the integration level of the rear bumper assembly 100 can be improved. Specifically, direct connection means that the first functional module 122 and the second functional module 123 do not need to be connected to the plastic bracket 121 through their respective mounting brackets or other structures. Therefore, the structure, production, and assembly processes of the integrated component 120 can be simplified, the integration level of the rear bumper assembly 100 can be improved, and the production cost of the integrated component 120 can be reduced, thereby reducing the production cost of the rear bumper assembly 100.
[0069] It is easy to understand that when the first functional module 122 and the second functional module 123 are fixed to the plastic bracket 121 by the mounting bracket, on the one hand, there will be costs for the raw materials, processing, and maintenance of the mounting bracket; on the other hand, the mounting bracket needs to be fixed to the plastic bracket 121 by means of fasteners or other structures, which can easily lead to the complexity of the assembly process and increase the assembly cost. Therefore, in this embodiment of the application, the first functional module 122 and the second functional module 123 can be directly fixed to the plastic bracket 121, which is beneficial to reducing the above-mentioned costs, thereby reducing the cost of the rear bumper assembly 100.
[0070] The integrated component 120 may also include functional modules with other intelligent functions. Other functional modules can also be directly connected to the plastic bracket 121 to improve the integration of the integrated component 120, so that the integrated component 120 has more functions and is easy to assemble.
[0071] It should be noted that this embodiment does not limit the method by which the first functional module 122 and the second functional module 123 are fixed to the plastic bracket 121. The first functional module 122 and the second functional module 123 may be connected by one or more of the following methods, including but not limited to locking fasteners, snap-fit, and crimping.
[0072] In some examples, the first functional module 122 and the second functional module 123 can be a kind of intelligent functional module.
[0073] For example, the first functional module 122 and the second functional module 123 may be, but are not limited to, a camera module, a Bluetooth module, etc. For instance, the camera module may be a depth time-of-flight (DTOF) camera.
[0074] It should be noted that, for ease of description, this application embodiment uses the first functional module 122 as a camera module and the second functional module 123 as a Bluetooth module as an example for description.
[0075] Furthermore, in this embodiment, the plastic bracket 121 can be used to connect the rear skirt sheet metal 110 and the rear bumper body 130. The plastic bracket 121 can have a lighter weight, thereby reducing the weight of the rear bumper assembly 100, which is beneficial for achieving lightweight vehicle design and thus improving the range of electric vehicles.
[0076] In some embodiments of this application, reference is made to Figures 4 to 10 A limiting structure 131 is provided on the surface of the rear bumper body 130 facing the rear skirt sheet metal 110. The limiting structure 131 is located on the outer periphery of the mounting opening 130a. The limiting structure 131 is used to connect with the first functional module 122 when a part of the first functional module 122 passes through the mounting opening 130a.
[0077] In this embodiment, one end of the first functional module 122 can be fixed to the plastic bracket 121. The other end of the first functional module 122 can be connected to the limiting structure 131. Therefore, a portion of the first functional module 122 can be located between the plastic bracket 121 and the rear bumper body 130. The plastic bracket 121 and the rear bumper body 130 can provide relative support to the first functional module 122, so that the first functional module 122 can remain stable during vehicle operation.
[0078] Specifically, the limiting structure 131 ensures a stable connection between the first functional module 122 and the rear bumper body 130, improving the reliability of their connection. Furthermore, the first functional module 122 and the rear bumper body 130 do not require locking with other fasteners, mounting brackets, or other structures. This simplifies the assembly process of the first functional module 122 and eliminates the need for drilling holes in the rear bumper body 130, thus improving its appearance.
[0079] When the first functional module 122 is a camera module, a portion of the first functional module 122 can be inserted into the mounting port 130a of the rear bumper body 130 for real-time shooting of the rear side of the vehicle.
[0080] In this embodiment, the specific structure of the limiting structure 131 is not limited. The limiting structure 131 can abut against the first functional module 122 and limit the relative position of the first functional module 122 and the rear bumper body 130.
[0081] In some examples, refer to Figure 7 and Figure 8One end of the first functional module 122 can be connected to the plastic bracket 121 via a locking fastener. Then, when the plastic bracket 121 is connected to the rear bumper body 130, the other end of the first functional module 122 is connected to the limiting structure 131. The locking fastener can be a screw 124.
[0082] Furthermore, in some embodiments of this application, reference is made to... Figure 5 and Figure 6 The limiting structure 131 includes a first limiting surface 131a. The first limiting surface 131a faces the center of the mounting opening 130a. The first limiting surface 131a is connected to the first functional module 122 to constrain the gap between the outer peripheral sidewall of the first functional module 122 and the inner wall of the mounting opening 130a.
[0083] In this embodiment, the first limiting surface 131a can be used to connect with a portion of the outer peripheral sidewall of the first functional module 122. Since a portion of the first functional module 122 can pass through the mounting opening 130a, the connection between the first limiting surface 131a and the outer peripheral sidewall of the first functional module 122 makes it less likely for the first functional module 122 to shift outwards. This helps ensure that the gap between the outer peripheral sidewall of the first functional module 122 and the inner wall of the mounting opening 130a meets the appearance requirements of the rear bumper assembly 100.
[0084] Specifically, the exterior surface of the rear bumper assembly 100 can be the surface of the rear bumper body facing away from the rear skirt sheet metal 110. When the gap between the outer peripheral sidewall of the first functional module 122 and the inner wall of the mounting opening 130a is large, external dust, impurities, etc., can easily accumulate in the gap. Furthermore, the first functional module 122 has multiple outer peripheral sidewalls. When the gaps between different outer peripheral sidewalls and the inner wall of the mounting opening 130a are inconsistent, it will affect the appearance of the rear bumper assembly 100. Therefore, the above problems can be effectively solved by the cooperation between the first limiting surface 131a and the first functional module 122.
[0085] In some embodiments of this application, reference is made to Figure 5 and Figure 6 The limiting structure 131 includes a second limiting surface 131b. The second limiting surface 131b faces the plastic bracket 121. The second limiting surface 131b is connected to the first functional module 122 to constrain the height of the first functional module 122 protruding from the rear surface of the rear bumper body 130.
[0086] In this embodiment, when the first functional module 122 is a camera module, a portion of the first functional module 122 can pass through the mounting port 130a. The first functional module 122 is connected via a second limiting surface 131b. The second limiting surface 131b provides support to the first functional module 122 towards the plastic bracket 121, ensuring that the exposed surface of the first functional module 122 does not protrude excessively from the rear surface (appearance surface) of the rear bumper body 130. This reduces the likelihood that the first functional module 122 will be easily damaged by external forces due to excessive protrusion.
[0087] Additionally, it should be noted that the exposed surface of the first functional module 122 can refer to the surface of the first functional module 122 facing away from the plastic bracket 121. The exposed surface of the first functional module 122 can be located within the mounting opening 130a, or the exposed surface of the first functional module 122 can protrude from the rear surface of the rear bumper body 130.
[0088] In some examples, the limiting structure 131 may be arranged around the outer periphery of the mounting port 130a. Alternatively, refer to... Figure 9 and Figure 10 The limiting structure 131 may include a plurality of limiting parts 1311. The plurality of limiting parts 1311 may be evenly distributed at intervals on the outer periphery of the mounting port 130a.
[0089] Based on this, refer to Figure 11 and Figure 12 In some embodiments of this application, the plastic bracket 121 is provided with a snap-fit connector 1211. The second functional module 123 is detachably connected to the plastic bracket 121 via the snap-fit connector 1211.
[0090] In this embodiment, the plastic bracket 121 is detachably connected to the plastic bracket 121 via the snap-fit connector 1211, which enables quick assembly and disassembly of the second functional module 123, thereby improving the ease of installation of the second functional module 123 and the plastic bracket 121, and facilitating the maintenance and repair of the second functional module 123.
[0091] In some examples, refer to Figure 13 The second functional module 123 can be initially connected to the plastic bracket 121 via a locking fastener. Then, the second functional module 123 can be fixed to the plastic bracket 121 via a snap-fit fastener 1211. The locking fastener can be, but is not limited to, a screw 124.
[0092] Based on this, refer to Figures 14 to 16 In some embodiments of this application, the plastic bracket 121 is provided with a support portion 1212 facing the tail skirt sheet metal 110. The support portion 1212 abuts against the tail skirt sheet metal 110.
[0093] In this embodiment, the support portion 1212 abuts against the tail skirt sheet metal 110, and there is a relative force between the tail skirt sheet metal 110 and the support portion 1212, so that the plastic bracket 121 is not easy to flip backward, thereby maintaining the reliability of the connection between the plastic bracket 121 and the tail skirt sheet metal 110.
[0094] In some examples, the plastic bracket 121 and the rear skirt sheet 110 can be connected first by fasteners. Then, the support portion 1212 of the plastic bracket 121 can abut against the rear skirt sheet 110.
[0095] For example, refer to Figure 17 The plastic bracket 121 may be provided with a main positioning hole 121b. Correspondingly, the tail skirt sheet metal 110 may be provided with a welding bolt corresponding to the main positioning hole 121b. The welding bolt can be inserted into the main positioning hole 121b and locked with a nut so that the plastic bracket 121 and the tail skirt sheet metal 110 can be initially positioned.
[0096] Furthermore, the plastic bracket 121 may also be provided with auxiliary positioning holes 121c. Correspondingly, the rear skirt sheet metal 110 may be provided with welding bolts corresponding to the auxiliary positioning holes 121c. The welding bolts can be inserted into the auxiliary positioning holes 121c and locked with nuts to fix the plastic bracket 121 and the rear skirt sheet metal 110. The plastic bracket 121 and the rear skirt sheet metal 110 are not prone to relative movement along the width direction Y, height direction Z, and length direction X of the vehicle.
[0097] In some examples, there can be multiple main positioning holes 121b along the width direction Y of the vehicle. These multiple main positioning holes 121b can be located in or near the central region of the plastic bracket 121. Auxiliary positioning holes 121c can be located near the edge region of the plastic bracket 121.
[0098] For example, there may be five main positioning holes 121b and two auxiliary positioning holes 121c. Along the width direction Y of the vehicle, the two auxiliary positioning holes 121c may be located at both ends of the plastic bracket 121.
[0099] The auxiliary positioning hole 121c can be an oblong hole. The auxiliary positioning hole 121c can absorb the machining tolerances of the tail skirt sheet metal 110 and the plastic bracket 121, so as to facilitate the assembly of the plastic bracket 121 and the tail skirt sheet metal 110.
[0100] In some embodiments of this application, reference is made to Figure 10 and Figure 17One of the plastic bracket 121 and the rear bumper body 130 is provided with a limiting protrusion 1213. The other of the plastic bracket 121 and the rear bumper body 130 is provided with a limiting groove 130b. The limiting protrusion 1213 and the limiting groove 130b cooperate to fix the plastic bracket 121 and the rear bumper body 130 relative to each other in the width direction Y of the vehicle.
[0101] In this embodiment, at least a portion of the limiting protrusion 1213 may be located within the limiting groove 130b. The limiting groove 130b may have at least a first sidewall opposite to each other along the width direction Y of the vehicle. Therefore, the first sidewall opposite to each other in the limiting groove 130b makes it difficult for the limiting protrusion 1213 to move along the width direction Y of the vehicle, thereby making it difficult for the plastic bracket 121 and the rear bumper body 130 to undergo relative displacement along the width direction Y of the vehicle.
[0102] In some examples, the limiting groove 130b may have an upward opening along the height direction Z of the vehicle. During the connection of the plastic bracket 121 to the rear bumper body 130, the limiting protrusion 1213 may enter the limiting groove 130b from top to bottom through the opening of the limiting groove 130b.
[0103] Alternatively, the limiting protrusion 1213 can be horizontally inserted into the limiting groove 130b along the length X of the vehicle.
[0104] In some examples, with a limiting protrusion 1213 located on the plastic bracket 121 and a limiting groove 130b located on the rear bumper body 130, the limiting protrusion 1213 can be located in the middle region of the plastic bracket 121 along the width direction Y of the vehicle. The limiting groove 130b can be located in the middle region of the rear bumper body 130.
[0105] Furthermore, in some embodiments of this application, reference is made to... Figure 11 and Figure 18 One of the plastic bracket 121 and the rear bumper body 130 is provided with a snap-fit protrusion 1214. The other of the plastic bracket 121 and the rear bumper body 130 is provided with a snap-fit groove 130c. The snap-fit protrusion 1214 and the snap-fit groove 130c cooperate to fix the plastic bracket 121 and the rear bumper body 130 relative to each other along the length direction X of the vehicle.
[0106] In this embodiment, at least a portion of the snap-fit protrusion 1214 may be located within the snap-fit groove 130c. The snap-fit groove 130c may have at least two opposing second sidewalls along the vehicle's length direction X. Therefore, the opposing second sidewalls of the snap-fit groove 130c prevent the snap-fit protrusion 1214 from moving easily along the vehicle's length direction X, thereby preventing the plastic bracket 121 and the rear bumper body 130 from easily displacing relative to each other along the vehicle's length direction X.
[0107] In some examples, the snap-fit protrusion 1214 can be elastic. During the connection process between the plastic bracket 121 and the rear bumper body 130, taking an example where the snap-fit protrusion 1214 is located on the plastic bracket 121 and the snap-fit groove 130c is located on the rear bumper body 130, the snap-fit protrusion 1214 can interact with the rear bumper body 130 before reaching the snap-fit groove 130c. At this time, the snap-fit protrusion 1214 can deform. When the snap-fit protrusion 1214 reaches the snap-fit groove 130c, it can release its elastic potential energy and enter the snap-fit groove 130c. The snap-fit protrusion 1214 can not easily detach from the snap-fit groove 130c along the length direction X of the vehicle.
[0108] In some examples, the number of snap-fit protrusions 1214 may be, but is not limited to, one. When there are multiple snap-fit protrusions 1214, the multiple snap-fit protrusions 1214 may be spaced apart along the width direction Y of the vehicle.
[0109] For example, the snap-fit protrusions 1214 can be evenly distributed on the plastic bracket 121. The number of snap-fit protrusions 1214 can be, but is not limited to, ten.
[0110] Furthermore, in some embodiments of this application, reference is made to... Figure 10 and Figure 17 One of the plastic bracket 121 and the rear bumper body 130 is provided with a connector 130d. The other of the plastic bracket 121 and the rear bumper body 130 is provided with a connector groove 121a. The connector 130d cooperates with the connector groove 121a to at least limit the plastic bracket 121 and the rear bumper body 130 in the height direction Z of the vehicle.
[0111] In this embodiment, at least a portion of the insertion portion 130d may be located within the insertion groove 121a. The insertion groove 121a may have at least a third sidewall opposite to each other along the vehicle height direction Z. Therefore, the opposite third sidewall of the insertion groove 121a makes it difficult for the insertion portion 130d to move along the vehicle height direction Z, thereby making it difficult for the plastic bracket 121 and the rear bumper body 130 to undergo relative displacement along the vehicle height direction Z.
[0112] In some examples, the rear bumper body 130 is provided with a plug-in portion 130d and the plastic bracket 121 is provided with a plug-in groove 121a. During the connection process between the plastic bracket 121 and the rear bumper body 130, the plug-in portion 130d can be inserted into the plug-in groove 121a.
[0113] In some examples, there can be multiple connectors 130d. The number and position of the corresponding connector slots 121a match the connectors 130d. These multiple connectors 130d can be spaced apart along the width direction Y of the vehicle.
[0114] Furthermore, in some embodiments of this application, reference is made to... Figure 1 and Figure 19 Along the height direction Z of the vehicle, the plastic bracket 121 has a support surface 1215 facing the rear bumper body 130. The support surface 1215 is connected to the rear bumper body 130.
[0115] In this embodiment of the application, by providing the support surface 1215, the plastic bracket 121 can provide upward support to the rear bumper body 130, thereby providing upward rigidity to the rear bumper body 130, which is beneficial to improving the overall strength of the rear bumper assembly 100.
[0116] In some examples, the support surface 1215 may face upwards along the height direction Z of the vehicle. The support surface 1215 may fit against the inner skin of the rear bumper body 130.
[0117] This application embodiment can also provide a vehicle. The vehicle may include a body and the rear bumper assembly 100 in any of the above embodiments.
[0118] In this embodiment, the rear bumper assembly 100 can integrate at least a first functional module 122 and a second functional module 123, which is beneficial for optimizing production, processing, and assembly processes and reducing corresponding costs. Furthermore, the plastic bracket 121 of the rear bumper assembly 100 is lightweight, enabling weight reduction of the rear bumper assembly 100 and thus the vehicle itself, which helps improve the vehicle's range.
[0119] The sequence numbers of the embodiments in this application are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments. The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made based on the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
