Abstract
Description
Technical Field
[0001] This application relates to the technical field of transportation vehicles, and particularly to a rear bumper bracket, a rear bumper assembly, and a vehicle thereof. Background Art
[0002] The rear bumper bracket is arranged at the rear end of the vehicle, and its main function is to install the rear bumper. The rear bumper is basically installed on the bracket by a snap connection method. However, when installing the rear bumper, it is generally a blind installation, and at this time, it is impossible to clearly see the snap-fit position between the rear bumper and the bracket. Therefore, problems such as jamming or displacement are likely to occur during the assembly process; moreover, blind installation also poses a relatively high requirement for the skills and abilities of the assembly personnel, but the basic abilities of the assembly personnel vary greatly, resulting in greater difficulties in assembling the rear bumper. Summary of the Utility Model
[0003] Based on this, it is necessary to provide a rear bumper bracket, a rear bumper assembly, and a vehicle thereof that can avoid jamming or displacement during the assembly process and reduce the assembly difficulty.
[0004] To solve the above technical problems, the present application provides the following technical solutions:
[0005] A rear bumper bracket, the rear bumper bracket includes:
[0006] A frame body provided with a snap portion for snap-connecting the rear bumper;
[0007] A baffle plate arranged on the side of the frame body;
[0008] A flanging is arranged above the baffle plate along the height direction of the vehicle and is connected to the baffle plate, and the position of the flanging is correspondingly set with the position of the snap portion;
[0009] Wherein, a retaining edge groove is formed between the flanging and the frame body, and the opening of the retaining edge groove faces the snap portion.
[0010] In this application, by setting the baffle plate and the flanging, and a retaining edge groove is formed between the flanging and the frame body, during the assembly process of the rear bumper, the flanging can be used to block the rear bumper and make it enter the retaining edge groove, and then the retaining edge groove is used to limit the rear bumper, avoiding the problems of jamming or displacement of the rear bumper; at the same time, the position of the flanging is correspondingly set with the position of the snap portion. When the rear bumper enters the retaining edge groove, its position is accurate, that is, the rear bumper can be accurately snap-connected with the rear bumper bracket, effectively reducing the blind installation difficulty and improving the blind installation efficiency.
[0011] In one of the embodiments, the opening is in a flared shape, and the inner diameter of the flared opening gradually decreases from the snap portion to the baffle plate direction.
[0012] It is understandable that the trumpet-shaped opening can be used for guiding during the assembly process of the rear bumper, enabling the rear bumper to quickly pass through the opening and be inserted into the rib groove, thereby achieving the limit of the rear bumper.
[0013] In one embodiment, the flanging and the baffle are configured as an integral structure.
[0014] In one embodiment, the baffle and the frame body are configured as an integral structure.
[0015] The present application also provides the following technical solutions:
[0016] A rear bumper assembly includes a rear bumper and the rear bumper bracket described in any one of the above embodiments. The rear bumper is provided with a plug-in board and a matching part. The plug-in board can be plugged into the rib groove, and the matching part is arranged on the plug-in board and is used for snap connection with the clamping part.
[0017] In one embodiment, a guiding surface is arranged on the plug-in board, and the guiding surface faces the flanging.
[0018] In one embodiment, a lapping board is further arranged on the rear bumper, and a receiving groove is formed between the lapping board and the plug-in board;
[0019] The flanging can be received in the receiving groove.
[0020] In one embodiment, the lapping board and the flanging are arranged at an interval; and at the gap between the lapping board and the flanging, a plurality of connecting ribs are arranged on the flanging at intervals along the vehicle width direction. It should be noted that the lapping board laps on the flanging. Due to processing and assembly errors, problems such as assembly interference may occur between the lapping board and the flanging. At this time, if the structure of the lapping board or the flanging is adjusted, the overall mold needs to be modified, and the modification cost is relatively high. However, in the present application, by setting a gap and arranging connecting ribs at this gap position, if interference problems occur, the size of the connecting ribs can be adjusted to meet the assembly requirements between the lapping board and the flanging, and the modification cost is lower. At the same time, the lapping board is used for lapping the rear door panel. Therefore, after the rear bumper is assembled, it is necessary to ensure that the surface difference between the rear bumper and the rear door panel meets the requirements. The connecting ribs here can also prevent the lapping board from sinking (i.e., the rear bumper sinks), thereby avoiding the gap between the rear bumper and the rear door panel from sagging.
[0021] In one embodiment, an alignment structure is arranged between the rear bumper and the rear bumper bracket.
[0022] It can be understood that the alignment structure is provided to provide preliminary positioning for the installation of the rear bumper during the rear bumper assembly process, further improving the efficiency of the blind installation of the rear bumper.
[0023] The present application also provides the following technical solutions:
[0024] A vehicle includes the rear bumper assembly described in any of the above embodiments.
[0025] Compared with the prior art, the rear bumper bracket, the rear bumper assembly and the vehicle thereof are provided with a baffle and a flanging, and a retaining edge groove is formed between the flanging and the frame body. Thus, during the rear bumper assembly process, the flanging can be used to block the rear bumper and make it enter the retaining edge groove, and then the retaining edge groove is used to limit the rear bumper, avoiding the problems of the rear bumper jamming or shifting; at the same time, the position of the flanging is correspondingly arranged with the position of the clamping portion. When the rear bumper enters the retaining edge groove, its position is accurate, that is, the rear bumper can be accurately clamped with the rear bumper bracket, effectively reducing the difficulty of blind installation and improving the efficiency of blind installation.

[0044] Please refer to Figures 1 to 9 , this application provides a rear bumper bracket 100, which is used to install a rear bumper 210. Here, the rear bumper bracket 100 is configured as a middle bracket, that is, the rear bumper 100 is relatively located in the middle position of the vehicle along the width direction y of the vehicle. In other words, brackets for installing the rear bumper 210 will also be provided with left and / or right brackets, etc. in the width direction y of the vehicle. In this embodiment, taking the bracket located in the middle of the vehicle as an example, the structure and principle of this application will be described.
[0045] Specifically, refer to Figures 2 to 6, the rear bumper bracket 100 includes a frame body 10, a baffle 20 and a flanging 30. A clamping portion 11 is provided on the frame body 10, and the clamping portion 11 is used to clamp the rear bumper 210, thereby realizing the connection between the rear bumper bracket 100 and the rear bumper 210; the baffle 20 is arranged on the side of the frame body 10; the flanging 30 is arranged above the baffle 20 along the vehicle height direction z and is connected to the baffle 20, and the position of the flanging 30 is correspondingly set with the position of the clamping portion 11; wherein, a retaining edge groove 31 is formed between the flanging 30 and the frame body 10, and the opening 32 of the retaining edge groove 31 faces the clamping portion 11. Here, by forming the retaining edge groove 31 between the flanging 30 and the frame body 10, during the assembly process of the rear bumper 210, the flanging 30 can be used to block it and make it enter the retaining edge groove 31, and then the retaining edge groove 31 is used to limit the rear bumper 210 to prevent the rear bumper 210 from jamming or shifting; at the same time, the position of the flanging 30 is correspondingly set with the position of the clamping portion 11. When the rear bumper 210 enters the retaining edge groove 31, its position is accurate, that is, the rear bumper 210 can be accurately clamped with the rear bumper bracket 100, effectively reducing the blind assembly difficulty and improving the blind assembly efficiency.
[0046] Preferably, the frame body 10 is generally set as a plastic part, and the frame body 10 is generally formed by injection molding. Of course, the material of the frame body 10 is not limited to this, and it can be set according to requirements.
[0047] Furthermore, the baffle 20 is set as a plastic part, and it can be set as an integral structure with the frame body 10 to improve the overall structural strength of the rear bumper bracket 100. Of course, the material of the baffle 20 is not limited to this, and it can be set according to requirements.
[0048] In an embodiment, the flanging 30 is set as a plastic part, and it can be configured as an integral structure with the baffle 20, so as to improve the structural strength of the flanging 30. Of course, the material of the flanging 30 is not limited to this, and it can be set according to requirements.
[0049] Preferably, the frame body 10, the baffle 20 and the flanging 30 are integrally injection molded, which is convenient for the overall processing of the rear bumper bracket 100, reduces the processing steps and improves the structural strength of the rear bumper bracket 100.
[0050] In an embodiment, refer to Figure 3 and Figure 6, the opening 32 is arranged in a flared shape, and the inner diameter of the flared opening 32 gradually decreases from the clamping portion 11 to the baffle 20, that is, the end with a larger inner diameter of the opening 32 faces the clamping portion 11. In this way, during the assembly process of the rear bumper 210, the flared opening 32 can be used to guide the movement of the rear bumper 210, so that the rear bumper 210 can quickly pass through the opening 32 and be inserted into the edge slot 31 to achieve the limit of the rear bumper 210.
[0051] Specifically, at the position of the opening 32, a slope is arranged on one side of the flanging 30 located in the edge slot 31. In this way, the overall opening 32 presents a flared shape due to the inclination of the slope.
[0052] As Figure 1 , Figure 3 and Figure 4 shown, the present application also provides a rear bumper assembly 200, which includes a rear bumper 210 and a rear bumper bracket 100. A plug-in board 211 and a matching portion 212 are arranged on the rear bumper 210. The plug-in board 211 can be plugged into the edge slot 31, and the matching portion 212 is arranged on the plug-in board 211 and is used for snap connection with the clamping portion 11. Here, the matching portion 212 can be configured as a slot, and the clamping portion 11 can be configured as a protrusion, so that the protrusion and the slot are snap-connected. Of course, it can also be that the matching portion 212 can be configured as a protrusion, and the clamping portion 11 can be configured as a slot.
[0053] Furthermore, as Figure 3 , Figure 8 and Figure 9 shown, a guiding surface 213 is arranged on the plug-in board 211, and the guiding surface 213 faces the flanging 30. The guiding surface 213 can be used to guide the movement of the plug-in board 211, so that the plug-in board 211 can be quickly inserted into the edge slot 31.
[0054] In an embodiment, referring to Figure 6 , a lapping board 214 is further arranged on the rear bumper 210, and an accommodating groove 215 is formed between the lapping board 214 and the plug-in board 211; the flanging 30 can be accommodated in the accommodating groove 215. In this way, the connection between the rear bumper 210 and the rear bumper bracket 100 is made more compact.
[0055] Preferably, in combination with Figure 7As shown, the overlapping plate 214 is arranged at intervals from the flanging 30; and at the gap between the overlapping plate 214 and the flanging 30, a plurality of connecting ribs 33 are arranged on the flanging 30 at intervals along the vehicle width direction y. It should be noted that the overlapping plate 214 overlaps on the flanging 30. Due to processing and assembly errors, problems such as assembly interference may occur between the overlapping plate 214 and the flanging 30. At this time, if the structure of the overlapping plate 214 or the flanging 30 is adjusted, the overall mold needs to be modified, and the modification cost is relatively high. However, in this application, by setting a gap and arranging the connecting ribs 33 at this gap position, if problems such as interference occur, the size of the connecting ribs 33 can be adjusted to meet the assembly requirements between the overlapping plate 214 and the flanging 30, and the modification cost is lower. At the same time, the overlapping plate 214 is used to overlap the rear door panel 300. Therefore, after the rear bumper 210 is assembled, the surface difference between the rear bumper 210 and the rear door panel 300 needs to meet the requirements, and the connecting ribs 33 here can also prevent the overlapping plate 214 from sinking (i.e., the rear bumper 210 sinks), thereby preventing the gap between the rear bumper 210 and the rear door panel 300 from sagging.
[0056] In one embodiment, as Figure 7 and Figure 9 shown, an alignment structure 220 is provided between the rear bumper 210 and the rear bumper bracket 100. Here, the setting of the alignment structure 220 can provide preliminary positioning for the installation of the rear bumper 210 during the assembly process of the rear bumper 210, and further improve the efficiency of blind installation of the rear bumper 210.
[0057] Preferably, referring to Figure 7 and Figure 9 , the alignment structure 220 includes a convex portion 221 and a groove 222. The convex portion 221 is arranged on the rear bumper bracket 100, and the groove 222 is located on the rear bumper 210. Or, the convex portion 221 is arranged on the rear bumper 210, and the groove 222 is located on the rear bumper bracket 100. During the installation process of the rear bumper 210, the installation position of the rear bumper 210 can be initially determined by the alignment of the convex portion 221 and the groove 222.
[0058] This application also provides a vehicle, including the rear bumper assembly 200 of any one of the above embodiments.
[0059] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combinations of these technical features do not conflict, they should be considered as the scope described in this specification.
[0060] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patented application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the patent protection scope of the present application shall be subject to the appended claims.
