Detailed Implementation

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0021] The rear bumper assembly 100 of this application will now be described in detail with reference to the accompanying drawings and embodiments. The rear bumper assembly 100 is applied to a vehicle and can absorb and buffer external impact forces at the rear of the vehicle body to improve the vehicle's collision performance.

[0022] Currently, the matching method between the rear bumper and the side panel in a vehicle is usually as follows: a bracket structure (i.e., sheet metal bracket 200) is set on the body sheet metal, and the bracket structure is installed and cooperated with the connecting structure formed by the flange at the upper end of the rear bumper to achieve the assembly and fixation of the rear bumper on the body sheet metal.

[0023] In related technologies, the design of the rear bumper and the limitations of the body sheet metal processing technology prevent the direct formation of a connecting structure (i.e., the aforementioned flange) at the rear bumper, thus preventing the rear bumper from being mounted on the body sheet metal. Forcing a connecting structure at the rear bumper would result in a significant risk of cracking at that connection point.

[0024] According to the embodiments of this application, the rear bumper assembly 100 is mounted on the body sheet metal, and a sheet metal bracket 200 is provided on the body sheet metal. The sheet metal bracket 200 is fixedly connected to the body sheet metal to form an installation structure on the body sheet metal. The rear bumper assembly 100 is assembled and fixed on the body sheet metal by connecting and cooperating with the installation structure, thereby realizing the installation of the rear bumper assembly 100.

[0025] According to an embodiment of this application, the rear bumper assembly 100 includes a bumper body 1 and a mounting bracket 2. The bumper body 1 has a cavity 101 with an open end facing forward. The mounting bracket 2 is disposed in the cavity 101 and is connected and cooperates with the bumper body 1. A connecting portion 201 is formed on the mounting bracket 2, which is used to connect and cooperate with a sheet metal bracket 200 to fix the bumper body 1 to the body sheet metal.

[0026] It should be noted that the bumper body 1 in this embodiment is equivalent to the "rear bumper" that cannot form a flange structure for connecting and cooperating with the sheet metal bracket 200. In other words, the bumper body 1 in this application cannot be directly fixedly connected to the sheet metal bracket 200.

[0027] In this application, the rear bumper assembly 100 consists of a bumper body 1 and a mounting bracket 2. The mounting bracket 2 is connected and fixed to the bumper body 1. The mounting bracket 2 has a connecting portion 201 for connecting and engaging with a sheet metal bracket 200, so that the mounting bracket 2 is mounted and fixed to the sheet metal bracket 200 through the connecting portion 201, allowing the bumper body 1 to be fixed to the sheet metal bracket 200 via the mounting bracket 2. This reduces the difficulty of developing the shape of the bumper body 1, and even if no mounting structure is formed on the bumper body 1, the assembly requirements between the bumper body 1 and the vehicle body sheet metal can still be met.

[0028] Furthermore, the bumper body 1 has a forward-opening cavity 101, which can accommodate the mounting bracket 2. This allows the mounting bracket 2 to be arranged within the cavity 101, saving space and ensuring a tight fit between the mounting bracket 2 and the bumper body 1. This facilitates the connection and fixation of the bumper body 1 to the sheet metal bracket 200 via the mounting bracket 2. Simultaneously, the mounting bracket 2 further enhances the deformation resistance of the bumper body 1, contributing to improved structural strength of the rear bumper assembly 100.

[0029] It is understandable that the mounting bracket 2 is set in the cavity 101 formed by the bumper body 1, and the mounting bracket 2 is connected and cooperated with the bumper body 1, so that at least the local strength of the bumper body 1 can be improved by the mounting bracket 2, which helps to improve the deformation resistance of the bumper body 1.

[0030] According to the rear bumper assembly 100 of this application embodiment, the bumper body 1 is connected and cooperated with the mounting bracket 2 so as to fix the bumper body 1 to the body sheet metal through the connection and cooperation of the mounting bracket 2 and the sheet metal bracket 200. This solves the problem that the bumper body 1 cannot form a connection structure due to the shape problem, meets the installation requirements of the bumper body 1 on the body sheet metal, and can improve the structural strength of the bumper body 1 through the mounting bracket 2, which helps to improve the deformation resistance of the rear bumper assembly 100.

[0031] In a further embodiment of this application, the bumper body 1 includes a main body segment 11 and two mounting segments 12. The main body segment 11 encloses and forms a first cavity 1011 that opens to the front side, so as to improve the local strength of the main body segment 11 by forming a cavity structure. The two mounting segments 12 are respectively connected to both sides of the main body segment 11 in the length direction, and each mounting segment 12 encloses and forms a second cavity 1012 that communicates and cooperates with the first cavity 1011. The mounting bracket 2 is disposed at the second cavity 1012.

[0032] The first cavity 1011 is connected to two second cavities 1012 respectively, and the first cavity 1011 and the second cavity 1012 cooperate to form the cavity 101 mentioned above. The length direction of the main body segment 11 is the Y direction of the vehicle, which is also the left and right direction of the vehicle.

[0033] Combination Figure 2 , Figure 3 and Figure 5 As shown, part of the second cavity 1012 protrudes upward from the first cavity 1011, and the second cavity 1012 is connected to the first cavity 1011 and together they form the cavity 101, and the mounting bracket 2 is provided at the second cavity 1012.

[0034] It is understood that the bumper body 1 has two mounting sections 12, each with a set of mounting brackets 2. Each set of mounting brackets 2 is connected and fixed to the mounting section 12, thereby forming a connection structure (i.e., the aforementioned connection part 201) on both sides of the bumper body 1 through the two sets of mounting brackets 2. This allows the bumper assembly to be connected and fixed to the sheet metal brackets 200 on the left and right sides of the vehicle body sheet metal through the two sets of mounting brackets 2, improving the installation reliability of the rear bumper assembly 100 to the vehicle body sheet metal. The bumper assembly has a symmetrical structure, and correspondingly, the two sets of mounting brackets 2 in the bumper assembly also have a symmetrical structure.

[0035] It should be noted that when the rear bumper assembly 100 is installed on the vehicle body sheet metal, the main body section 11 of the bumper body 1 is located in the middle area of ​​the vehicle in the width direction, and the main body section 11 is set below the tailgate of the vehicle to form a protective structure at the rear of the vehicle. The mounting section 12 of the bumper body 1 is set near the rear end of the side sheet metal in the vehicle body sheet metal so that the mounting bracket 2 arranged in the mounting section 12 corresponds to the sheet metal bracket 200 fixed on the side sheet metal, so as to facilitate the installation and fixing of the mounting bracket 2 and the sheet metal bracket 200.

[0036] The sheet metal bracket 200 can be assembled onto the side panel sheet metal via a threaded connection, which is simple and highly reliable. For example, the sheet metal bracket 200 is positioned and engaged with the side panel sheet metal through a positioning structure, and is fixed to the side panel sheet metal through threaded connection parts 201 (such as bolts, screws, etc.), thereby achieving the installation and fixation of the sheet metal bracket 200 and the side panel sheet metal.

[0037] Reference Figure 3 As shown, part of the second cavity 1012 protrudes from the first cavity 1011 in the vertical direction to increase the accommodating space at the mounting section 12 and facilitate the matching of the bumper body 1 with the body sheet metal side, so that the mounting bracket 2 set in the second cavity 1012 can be correspondingly set with the sheet metal bracket 200.

[0038] Combination Figure 6 and Figure 7 As shown, in a further embodiment of this application, the mounting bracket 2 includes a bracket body 21, which is mounted on the mounting section 12, and the bracket body 21 forms the aforementioned connecting portion 201, so that the bracket body 21 can be connected and fixed to the sheet metal bracket 200 through the connecting portion 201.

[0039] When mounting bracket 2 and sheet metal bracket 200 are installed and coordinated, bracket body 21 and sheet metal bracket 200 are arranged opposite each other in the front-back direction, so that bracket body 21 and sheet metal bracket 200 can be fully corresponded, which facilitates the connection and fixation of bracket body 21 and sheet metal bracket 200.

[0040] It should be noted that the preferred installation method for the connecting part 201 and the sheet metal bracket 200 is a snap-fit ​​connection. The snap-fit ​​connection method is simple to install, making it easy to connect and fix the bracket 2 to the sheet metal bracket 200 through the connecting part 201. Furthermore, the snap-fit ​​connection method has high installation reliability, which can ensure the installation reliability of the rear bumper assembly 100 and the body sheet metal.

[0041] Combination Figure 6 and Figure 7 As shown in a further embodiment of this application, the bracket body 21 includes: a main board segment 211, an upper plate segment 212, and a lower plate segment 213. The main board segment 211 and the mounting segment 12 are arranged opposite to each other in the front-rear direction. The upper plate segment 212 and the lower plate segment 213 are respectively connected to the upper and lower sides of the main board segment 211, and the upper plate segment 212 and the lower plate segment 213 are arranged opposite to each other in the vertical direction. The upper plate segment 212, the main board segment 211, and the lower plate segment 213 form a U-shaped structure and enclose a cavity structure that opens to the front side, thereby improving the structural strength of the bracket body 21.

[0042] Furthermore, a connecting portion 201 is formed at the upper plate section 212, thereby allowing the connecting portion 201 to be positioned at the upper end adjacent to the mounting section 12, so that the rear bumper assembly 100 can be connected and fixed to the sheet metal bracket 200 at the upper position of the mounting section 12. The mounting section 12 has a second cavity 1012 that opens to the front, and the bracket body 21 is adapted to the spatial shape of the mounting section 12 where the second cavity 1012 is located, allowing the bracket body 21 to further enhance the structural strength of the mounting section 12, thereby improving the structural strength and deformation resistance of the rear bumper assembly 100 at the mounting section 12.

[0043] Reference Figure 7 As shown, it can be understood that a cavity structure (i.e., part of the second cavity 1012) matching the shape of the bracket body 21 is formed at the mounting section 12, so that the bracket body 21 can be arranged in the second cavity 1012. At the same time, the connecting part 201 formed at the upper plate section 212 can be set near the upper part of the mounting section 12, so that the mounting mating position of the rear bumper assembly 100 and the body sheet metal side can be set in the upper area of ​​the bumper assembly, which facilitates the assembly of the rear bumper assembly 100 to be assembled onto the body sheet metal by snap-fit.

[0044] In some embodiments of this application, the main board segment 211 is welded to the mounting segment 12 to fix the main board segment 211 to the mounting segment 12, thereby improving the reliability of the connection between the bracket body 21 and the mounting segment 12. This allows the mounting bracket 2 to be connected and fixed to the bumper body 1 as a whole, and the rear bumper assembly 100 (including the mounting bracket 2 and the rear bumper body 1) to be assembled together on the body sheet metal, which can reduce the assembly difficulty of the rear bumper assembly 100 and the body sheet metal.

[0045] In some embodiments of this application, the connecting part 201 is configured as a snap-fit ​​structure, and the connecting part 201 is used to snap-fit ​​with the sheet metal bracket 200. The installation method of the connecting part 201 and the sheet metal bracket 200 is simple and highly reliable.

[0046] It should be noted that the "click-fit structure" can be constructed as a slot, and correspondingly, a hook structure matching the slot is formed on the sheet metal bracket 200; the "click-fit structure" can also be constructed as a hook, and correspondingly, a slot structure matching the hook is formed on the sheet metal bracket 200. The specific construction of the click-fit structure is not limited here, as long as it satisfies the need for the mounting bracket 2 and the sheet metal bracket 200 to be click-fitted and fixed.

[0047] Furthermore, multiple connecting parts 201 can be provided on the bracket body 21, so that the mounting bracket 2 can be connected and fixed to the sheet metal bracket 200 through the multiple connecting parts 201, thereby improving the connection reliability between the mounting bracket 2 and the sheet metal bracket 200. Among them, the multiple connecting parts 201 are arranged sequentially at intervals along the length direction of the upper plate section 212 of the bracket body 21, and the length direction of the upper plate section 212 is also the width direction of the vehicle.

[0048] Reference Figure 6 As shown, in some embodiments of this application, the support body 21 further includes a reinforcing plate segment 214. The reinforcing plate segment 214 is arranged vertically and is connected to the main plate segment 211, the upper plate segment 212 and the lower plate segment 213 respectively, so as to form a support between the main plate segment 211, the upper plate segment 212 and the lower plate segment 213 through the reinforcing plate segment 214. This enhances the structural strength of the support body 21, helps to improve the deformation resistance of the support body 21, and thus improves the connection reliability between the support body 21 and the sheet metal support 200.

[0049] Combination Figure 6 and Figure 7 As shown, it can be understood that the support body 21 is formed into a U-shaped structure by the main plate segment 211, the upper plate segment 212 and the lower plate segment 213. The reinforcing plate segment 214 is set in the U-shaped structure to support the upper plate segment 212, the main plate segment 211 and the lower plate segment 213, thereby improving the deformation resistance of the support body 21 and reducing the risk of cracking and other problems at the support body 21.

[0050] Combination Figure 6 and Figure 7 As shown, in some embodiments of this application, the bracket body 21 further includes a support plate segment 215, which is disposed on the side opposite to the upper plate segment 212 and the mounting segment 12, and the support plate segment 215 is vertically supported between the upper plate segment 212 and the mounting segment 12 to improve the reliability of the fit between the upper plate segment 212 and the mounting segment 12.

[0051] Reference Figure 6 and Figure 7 As shown, it can be understood that the upper plate section 212 is arranged opposite to the wall of part of the installation section 12 in the vertical direction, and the upper plate section 212 and the wall of the installation section 12 are fitted with a gap to reserve a certain installation gap between the upper plate section 212 and the installation section 12, so as to facilitate the installation and fitting of the bracket body 21 and the installation section 12.

[0052] Furthermore, since the connecting portion 201 is formed at the upper plate section 212, the upper plate section 212 bears a higher load during the installation and mating of the rear bumper assembly 100 and the sheet metal bracket 200. In this application, by providing a support plate section 215 at the upper plate section 212, which is supported between the upper plate section 212 and the wall of the mounting section 12, the upper plate section 212 and the mounting section 12 can be supported and positioned, which helps to improve the structural strength and deformation resistance of the upper plate section 212, thereby improving the connection reliability of the mounting bracket 2 and the sheet metal bracket 200 at the upper plate section 212.

[0053] The bracket body 21 can be equipped with a reinforcing plate segment 214 and a supporting plate segment 215, which helps to improve the structural strength of the bracket body 21 itself and the reliability of the cooperation between the bracket body 21 and the mounting segment 12, and can ensure the reliability of the connection between the bumper body 1 and the sheet metal bracket 200 through the mounting bracket 2.

[0054] In some embodiments of this application, the mounting bracket 2 is provided with a connecting seat 216, which is used to install the connecting member 3 so as to connect and cooperate with the mounting section 12 through the connecting member 3. The connection method is simple and highly reliable, which can ensure the assembly reliability between the mounting bracket 2 and the mounting section 12.

[0055] Combination Figure 2 and Figure 6 As shown, it can be understood that the connecting seat 216 protrudes forward from the mounting bracket 2 to form an installation space at the connecting seat 216. The connector 3 can be installed from the front side of the connecting seat 216 to the rear side to connect and fix the mounting bracket 2 to the bumper body 1 at the connecting seat 216.

[0056] The connector 216 may have a hole structure for the connector 3 to pass through, and the connector 3 may be constructed as a screw or other connecting component to connect and fix the mounting bracket 2 to the bumper body 1.

[0057] It should be noted that multiple connecting seats 216 can be provided on the mounting bracket 2, allowing the mounting bracket 2 to be connected and fixed to the bumper body 1 through multiple connecting seats 216, which helps to improve the installation reliability of the mounting bracket 2 and the bumper body 1. The number of connecting seats 216 and their specific arrangement in the mounting bracket 2 are not specifically limited here; the arrangement of the connecting seats 216 in the mounting bracket 2 can be adapted to the shape of the mounting bracket 2.

[0058] In some embodiments of this application, the rear bumper assembly 100 further includes an adhesive layer (not shown), which is disposed between the bracket body 21 and the mounting section 12, and is used to bond the bracket body 21 and the mounting section 12 together to improve the connection reliability between the bracket body 21 and the mounting section 12.

[0059] The adhesive layer can be constructed as double-sided adhesive, with one side of the adhesive layer bonded to the outer surface of the bracket body 21 (i.e., the side surface of the bracket body 21 opposite to the mounting section 12), and the other side of the adhesive layer bonded to the inner wall surface of the mounting section 12 (i.e., the side surface of the mounting section 12 opposite to the bracket body 21), thereby bonding the adhesive layer between the bracket body 21 and the mounting section 12 to fix the bracket body 21 and the mounting section 12 together.

[0060] It should be noted that in the rear bumper assembly 100 of this application embodiment, the bumper body 1 is connected and fixed to the mounting bracket 2 so that the bumper body 1 and the mounting bracket 2 are assembled and fixed together on the sheet metal bracket 200.

[0061] Specifically, the mounting bracket 2 can first be glued and fixed to the bumper body 1 with an adhesive layer to position and engage with the bumper body 1, so that the mounting bracket 2 cannot wobble relative to the bumper body 1. Furthermore, the mounting bracket 2 can be connected and fixed to the bumper body 1 by at least one of the installation methods of welding and screwing, so as to improve the assembly reliability of the mounting bracket 2 and the bumper body 1, and connect the mounting bracket 2 and the bumper body 1 into one piece, thereby facilitating the subsequent assembly of the bumper body 1 and the mounting bracket 2 together on the sheet metal bracket 200.

[0062] Reference Figure 4 and Figure 6 As shown, in some embodiments of this application, the mounting bracket 2 further includes a first plate segment 22, which is connected to the bracket body 21 and extends forward in the front-rear direction. At least a portion of the first plate segment 22 is fitted against the wall of the mounting section 12 to support the wall of the mounting section 12, thereby improving the structural strength and deformation resistance of the mounting section 12 and reducing the risk of damage to the rear bumper assembly 100 due to collision.

[0063] It is understood that the first plate segment 22 is connected and cooperates with the bracket body 21, and the bracket body 21 extends forward from the bracket body 21, so that the first plate segment 22 and the mounting segment 12 can be connected in the Y direction of the vehicle (i.e., the width direction of the vehicle) to form a bracket structure. The first plate segment 22 can fit and cooperate with the inner wall of the mounting segment 12 to support the side wall of the mounting segment 12. The first plate segment 22 and the mounting segment 12 cooperate to form a double plate structure, thereby improving the structural strength of the rear bumper assembly 100 at the mounting segment 12 and helping to improve the lateral deformation resistance of the rear bumper assembly 100.

[0064] The first plate segment 22 is connected to one side of the bracket body 21 in the Y direction, and the first plate segment 22 can be connected and cooperated with the mounting segment 12 by adhesive bonding.

[0065] In some other embodiments of this application, the mounting bracket 2 further includes a second plate segment 23, which is connected to the bracket body 21 and extends forward in the front-rear direction. The second plate segment 23 is spaced apart from the wall of the mounting section 12, and the second plate segment 23 has a reinforcing rib 231 that is raised to the side of the wall of the mounting section 12 to further enhance the structural strength of the bracket body 21.

[0066] Understandably, the second plate segment 23 is connected to one side of the support body 21 in the Y direction, and extends forward to prevent interference between the second plate segment 23 and the mounting segment 12, and can also enhance the strength of the support body 21. Simultaneously, the second plate segment 23 has reinforcing ribs 231, giving it high structural strength.

[0067] It should be noted that the mounting bracket 2 can simultaneously be provided with a first plate segment 22 and a second plate segment 23. The first plate segment 22 and the second plate segment 23 can be connected to both sides of the bracket body 21 in the Y direction, for example: the first plate segment 22 is connected to the outer end of the bracket body 21 in the Y direction, and the second plate segment 23 is connected to the inner end of the bracket body 21 in the Y direction. Here, the aforementioned inner side refers to the side of the bracket body 21 closer to the vehicle's central axis, and correspondingly, the aforementioned outer side refers to the side of the bracket body 21 away from the vehicle's central axis.

[0068] Combination Figure 4 and Figure 6 As shown, in some embodiments of this application, the mounting bracket 2 further includes a mounting seat 24, which is disposed on the side wall of the mounting bracket 2 away from the mounting section 12 and protrudes forward, so as to form a mounting structure at the mounting bracket 2 through the mounting seat 24.

[0069] The mounting bracket 24 can be used to install other components located near the rear bumper assembly 100, such as fog lights and sensors. It is understood that the rear bumper assembly 100 is installed on the rear side of the vehicle, and the rear bumper assembly 100 can be used to house vehicle sensors, fog lights, and other devices. In existing rear bumpers, sensors, fog lights, and other devices can be directly fixed to the rear bumper (equivalent to the bumper body 1 in this application). Since this application provides a mounting bracket 2 on the front side of the bumper body 1, the rear bumper assembly 100 can be connected and fitted with the sheet metal bracket 200 through the mounting bracket 2. This increases the structural strength of the rear bumper assembly 100 by increasing the area corresponding to the mounting bracket 2 and the bumper body 1. Correspondingly, a mounting structure (i.e., the aforementioned mounting bracket 24) can be formed on the mounting bracket 2 to install and fix sensors, fog lights, and other devices, thereby simplifying the structure of the bumper body 1 and reducing the design and development difficulty of the bumper body 1.

[0070] It should be noted that the mounting base 24 can achieve its installation function by setting up mounting structures such as boss columns and mounting slots. The specific structure and arrangement of the mounting base 24 can be set according to the layout requirements of the device.

[0071] The rear bumper assembly 100 according to the embodiments of this application has at least the following advantages: (1) The bumper body 1 can be connected and fixed to the sheet metal bracket 200 on the body sheet metal by the mounting bracket 2, which can meet the installation requirements of the bumper body 1 on the body sheet metal and solve the problem that the bumper body 1 cannot form a connection structure due to the shape problem. (2) The mounting bracket 2 has high structural strength and the connection between the mounting bracket 2 and the bumper body 1 has high reliability, which can further improve the structural strength of the rear bumper assembly 100, thereby improving the deformation resistance of the rear bumper assembly 100 and reducing the risk of damage to the rear bumper assembly 100.

[0072] The vehicle according to an embodiment of this application includes the rear bumper assembly 100 described above.

[0073] The vehicle and the aforementioned bumper assembly have the same advantages over existing technologies, which will not be elaborated here.

[0074] Understandably, the vehicle also includes a body sheet metal and a sheet metal bracket 200. The sheet metal bracket 200 is screwed to the body sheet metal, and the sheet metal bracket 200 is provided with a snap-fit ​​part 210, which snaps into the mounting bracket 2. The snap-fit ​​part 210 can be constructed as a hook, a slot, or other snap-fit ​​structure, as long as it can satisfy the snap-fit ​​engagement of the connecting part 201.
