Description

Technical Field

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

[0002] With the rapid development of the automotive industry, people have higher and higher requirements for the overall refinement of the vehicle. Among them, the front bumper and hood, as the exterior structure of the vehicle, affect the overall refinement of the vehicle by the assembly gap between them in the front and rear directions.

[0003] Currently, there are two common assembly methods for front bumpers in vehicles. The first method utilizes a positioning structure between the front bumper and the vehicle body for positioning and assembly. The second method relies entirely on manual adjustment of the front bumper. However, the first method is limited by the precision of the components; relying solely on the precision of the components themselves results in a long dimensional chain, making it difficult to guarantee the clearance tolerance between the front bumper and the hood in the longitudinal direction of the vehicle. The second method, on the other hand, faces problems of poor clearance control stability and excessive cost. Therefore, the tolerance control capabilities of the front bumper and hood mating area under the existing technical system can no longer meet the stringent requirements of the current market for the overall appearance quality of vehicles. Utility Model Content

[0019] The first fastener is a bolt, which is adapted to pass through the second mounting hole and the first mounting hole to be tightened with a nut to limit and fix the positioning element to the positioning body. The bolt is also adapted to be loosened from the nut so that the bolt stops limiting and fixing the positioning element.

[0020] Optionally, there may be multiple positioning elements.

[0021] Optionally, multiple positioning elements are arranged sequentially at intervals along the left-right direction of the vehicle.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0045] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.

[0046] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0047] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0048] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0049] In this application, "multiple" refers to two or more (including two), and similarly, "multiple groups" refers to two or more (including two), and "multiple pieces" refers to two or more (including two).

[0050] It should be noted that with the rapid development of the automotive industry, people have higher and higher requirements for the overall refinement of the vehicle. Among them, the front bumper and hood, as the exterior structure of the vehicle, affect the overall refinement of the vehicle through their assembly gaps in the front-rear direction.

[0051] In related technologies, front bumpers for complete vehicles typically employ two assembly methods. The first method involves installing the front bumper to the vehicle body using a positioning structure. For example, 5-7 tightening points are set between the front bumper and the vehicle's mounting module, each with a locating pin positioned along the vehicle's longitudinal direction. However, this method is limited by component precision; relying solely on the component's own precision results in a long dimensional chain, making it difficult to guarantee the clearance tolerance between the front bumper and hood in the vehicle's longitudinal direction. The clearance tolerance between the front bumper and hood is generally only ±1.2∥1.2, resulting in a less refined appearance. The second method involves no positioning structure for the front bumper, relying entirely on manual adjustment for positioning. However, when the manual adjustment is excessive or the production cycle is too high, too many operators are required, leading to increased operating costs. Furthermore, the stability of manual adjustment is difficult to guarantee. Additionally, the clearance tolerance between the front bumper and hood in the vehicle's longitudinal direction is only ±0.8∥0.8, still resulting in insufficient refinement.

[0052] Therefore, the tolerance control capabilities of the existing technology system for the mating area between the front bumper and the hood are no longer sufficient to meet the current market's stringent requirements for the overall vehicle appearance quality.

[0053] Based on this, this application proposes a bumper assembly 100. When the positioning component 22 is in the adjustment state, the positioning component 22 and the bumper body 1 are positioned and assembled, which can flexibly adjust the position of the bumper body 1 along the front-rear direction X of the vehicle. This is to better control the gap tolerance between the bumper and the hood, so that the gap and surface difference between the bumper and the hood can reach the optimal level. This is beneficial to improving the overall appearance quality and refinement of the vehicle. Moreover, the adjustment method is simple and reliable, which is beneficial to improving assembly efficiency and reducing assembly costs.

[0054] The bumper assembly 100 and vehicle 1000 proposed in this application are described below with reference to the accompanying drawings.

[0055] like Figures 1-9 As shown, the bumper assembly 100 according to the first aspect of this application includes: a bumper body 1 and a positioning component 2.

[0056] The positioning component 2 includes a positioning body 21 and a positioning element 22. The positioning body 21 is used to fix the body 200 of the vehicle 1000. For example, the positioning body 21 can be constructed as a plate-like structure extending along the left-right direction Y of the vehicle. The two ends of the positioning body 21 are fixedly connected to the longitudinal beams of the body 200, and the connection methods include but are not limited to bolt connection, welding, etc.

[0057] The positioning element 22 is disposed on the positioning body 21. The positioning element 22 has a fixed state and an adjustable state relative to the positioning body 21. When the positioning element 22 is in the fixed state, it is fixedly connected to the positioning body 21. When the positioning element 22 is in the adjustable state, it can move relative to the positioning body 21 along the forward and backward direction X of the vehicle. That is to say, the positioning element 22 can switch between the fixed state and the adjustable state relative to the positioning body 21, so that the positioning element 22 can be fixedly connected to the positioning body 21. For example, the fixing methods between the positioning element 22 and the positioning body 21 include, but are not limited to, bolt fixing, clamping fixing, etc. Alternatively, when the positioning element 22 is switched to the adjustable state, it can move relative to the positioning body 21 along the forward and backward direction X of the vehicle under the drive of external force. It should be noted that during the movement of the positioning element 22 relative to the positioning body 21, the positioning element 22 is always installed on the positioning body 21, that is, the positioning element 22 will not separate from the positioning body 21, and the positioning element 22 can only move relative to the positioning body 21 along the forward and backward direction X of the vehicle.

[0058] Furthermore, the positioning component 22 is adapted to be positioned and assembled with the bumper body 1 so that the positioning component 22 restricts the movement of the bumper body 1 in the front-rear direction X of the vehicle. That is to say, during the assembly process of the positioning component 22 and the bumper body 1, the positioning component 22 also has the positioning function of restricting the movement of the bumper body 1 in the front-rear direction X of the vehicle, thereby ensuring the mutual limiting of the positioning component 22 and the bumper body 1 in the front-rear direction X of the vehicle. The limiting methods between the positioning component 22 and the bumper body 1 include, but are not limited to, abutment limiting, snap-fit ​​limiting, screw-fit limiting, etc.

[0059] To enable those skilled in the art to better understand this solution, as a specific example, during the installation of the bumper assembly 100, the positioning body 21 is fixedly installed on the vehicle body 200, and the positioning element 22 is installed on the positioning body 21. Optionally, the initial state of the positioning element 22 relative to the positioning body 21 is a tightened state. For example, such as... Figure 3 As shown, in the initial state, the positioning component 22 is fixedly installed on the positioning body 21 by the clamping device. During the installation of the bumper body 1, the bumper body 1 and the positioning component 22 are positioned and assembled. For example, the bumper body 1 is provided with a positioning pin and the positioning component 22 is provided with a positioning groove. The positioning pin of the bumper body 1 is inserted into the positioning groove of the positioning component 22 to limit the relative movement of the bumper body 1 and the positioning component 22 in the front-rear direction X of the vehicle.

[0060] After the bumper assembly 100 is installed, close the hood to measure the clearance tolerance between the bumper body 1 and the hood. If the clearance tolerance between the bumper body 1 and the hood is not up to standard, open the hood and switch the positioning component 22 to the adjustment state, for example, as... Figure 4As shown, loosen the clamping device to allow the positioning member 22 to move relative to the positioning body 21. Then, push and pull the bumper body 1 along the vehicle's front-rear direction X. It can be understood that because the positioning member 22 and the bumper body 1 are mutually limited in the vehicle's front-rear direction X, the bumper body 1 can drive the positioning member 22 to move relative to the positioning body 21 along the vehicle's front-rear direction X during the pushing and pulling process, so as to flexibly adjust the position of the bumper body 1. For example, the bumper body 1 is designed to be able to move at least ±3mm along the vehicle's front-rear direction X. After the position of the bumper body 1 is adjusted, fix the positioning member 22 on the positioning body 21 again through the clamping device, so that the positioning member 22 switches to the fastened state. Close the hood and measure the gap tolerance between the bumper body 1 and the hood again to see if it is qualified. If it is not qualified, repeat the above steps to adjust until the gap tolerance is qualified.

[0061] It can be seen that during the adjustment of the clearance tolerance between the bumper body 1 and the hood, when the positioning component 22 is switched to the adjustment state, the positioning assembly between the positioning component 22 and the bumper body 1 can flexibly adjust the position of the bumper body 1 along the X direction of the vehicle, so as to better control the clearance tolerance between the bumper and the hood, and ultimately make the clearance and surface difference between the bumper and the hood reach the optimal level, which is conducive to improving the overall appearance quality and refinement of the vehicle. Moreover, the adjustment method is simple and reliable, which is conducive to improving assembly efficiency and reducing assembly costs.

[0062] In some embodiments of this application, such as Figures 3-6 As shown, the positioning body 21 has a guide groove 211, and at least a portion of the positioning member 22 is disposed in the guide groove 211. When the positioning member 22 is in a fastened state, the positioning member 22 is fixedly connected to the guide groove 211. When the positioning member 22 is in an adjusted state, the positioning member 22 can move relative to the guide groove 211 along the front-rear direction X of the vehicle.

[0063] Specifically, such as Figure 6 As shown, the guide groove 211 of the positioning body 21 extends entirely along the longitudinal direction X of the vehicle. Furthermore, at least a portion of the positioning member 22 is installed within the guide groove 211. It can be understood that the positioning member 22 may be partially installed within the guide groove 211, or the positioning member 22 may be completely installed within the guide groove 211. For example, as... Figure 5As shown, when the positioning element 22 is partially installed in the guide groove 211, along the height direction Z of the vehicle, the height of the positioning element 22 is higher than the depth of the guide groove 211. Therefore, the positioning element 22 protrudes from the guide groove 211. When the positioning element 22 is in a fastened state, for example, when the positioning element 22 is fixedly installed on the positioning body 21 by a clamping device, the positioning element 22 is fixedly connected to the guide groove 211. When the positioning element 22 is switched to an adjustment state, for example, when the clamping device is loosened, along the front-rear direction X of the vehicle, the positioning element 22 can move relative to the guide groove 211. It should be noted that along the left-right direction Y of the vehicle, the side wall structure of the positioning element 22 and the guide groove 211 is clearance fit. Along the left-right direction Y of the vehicle, the single-sided clearance between the positioning element 22 and the side wall of the guide groove 211 is designed to be 0.1mm, which can provide good guiding function for the positioning element 22 while meeting the assembly requirements.

[0064] Therefore, by setting the guide groove 211, the stability of the positioning component 22 during movement can be guaranteed, and the deviation of the positioning component 22 in the forward and backward direction X of the vehicle can be prevented, which in turn helps to improve the adjustment accuracy of the bumper body.

[0065] In some embodiments of this application, the positioning member 22 may also be provided with a guide slider that is guided and fitted with the guide groove 211. When the positioning member 22 is in a fastened state, the guide slider is fixedly connected to the guide groove 211. When the positioning member 22 is in an adjusted state, the guide slider can move relative to the guide groove 211 along the front-rear direction X of the vehicle. For specific implementation details, please refer to the above description, which will not be repeated here.

[0066] In some embodiments of this application, such as Figure 3 , Figure 4 and Figure 7 As shown, the positioning component 22 has a positioning protrusion 221, and the bumper body 1 is provided with a positioning hole 11 for positioning and assembly with the positioning protrusion 221. The positioning hole 11 is adapted to restrict the positioning protrusion 221 from moving along the front-rear direction X of the vehicle.

[0067] Specifically, the positioning protrusion 221 of the positioning component 22 extends upward along the height direction Z of the vehicle. The bumper body 1 has a positioning hole 11. When the bumper body 1 and the positioning component 22 are positioned and assembled, the positioning protrusion 221 of the positioning component 22 is inserted into the positioning hole 11 of the bumper body 1, and along the front-rear direction X of the vehicle, the outer side wall of the positioning protrusion 221 abuts and is limited between the inner side wall of the positioning hole 11. With this setting, the positioning hole 11 and the positioning protrusion 221 are limited to move along the front-rear direction X of the vehicle by limiting the positioning protrusion 221 and the positioning hole 11, thereby limiting the movement of the bumper body 1 along the front-rear direction X of the vehicle. This makes it convenient to adjust the position of the bumper body 1 by pushing the bumper body 1 when the positioning component 22 is in the adjustment state. Moreover, the limiting method between the positioning protrusion 221 and the positioning hole 11 is simple and reliable, and easy to assemble. At the same time, the structure of the positioning protrusion 221 and the positioning hole 11 is relatively simple and easy to process, which helps to reduce production costs.

[0068] In some embodiments of this application, such as Figure 2 and Figure 7 As shown, the positioning protrusion 221 has a guide slope 2211, which is adapted to guide and drive the bumper body 1 so that the positioning protrusion 221 is positioned and assembled into the positioning hole 11.

[0069] Specifically, such as Figure 7 As shown, the positioning protrusion 221 is provided with a guide ramp 2211 for guiding and driving the bumper body 1. In this application, it is assumed that the bumper body 1 is installed from front to back along the front-rear direction X of the vehicle. In order to facilitate the positioning and assembly between the positioning protrusion 221 and the positioning hole 11, as shown... Figure 2 As shown, the guide slope 2211 is inclined upward along the height direction Z of the vehicle in the direction from front to back. With this configuration, when the bumper body 1 is installed from front to back along the front-to-back direction X of the vehicle, the bumper body 1 is gradually lifted upward under the action of the guide slope 2211. When the positioning hole 11 moves to the position opposite to the positioning protrusion 221, the bumper body 1 moves upward under its own rebound action, so that the positioning protrusion 221 can be inserted into the positioning hole 11. In this way, the positioning assembly efficiency between the positioning component 22 and the bumper body is greatly improved.

[0070] It should be noted that the tilt direction of the guide slope 2211 can be adjusted as needed according to the installation direction of the bumper body 1. No specific restrictions are imposed here, as long as it can guide and drive the bumper body 1.

[0071] In some embodiments of this application, such as Figure 2 and Figure 3As shown, the positioning component 2 further includes a first fastener 23, which is adapted to limit and fix the positioning member 22 to the positioning body 21 so that the positioning member 22 is in a fastened state. The first fastener 23 is also adapted to stop limiting and fixing the positioning member 22 so that the positioning member 22 is in an adjusted state.

[0072] Specifically, the first fastener 23 can be configured as a clamping structure or a snap-fit ​​structure. When the positioning component 22 needs to be switched to the fastened state, the first fastener 23 limits and fixes the positioning component 22 to the positioning body 21, so as to realize the fixed connection between the positioning component 22 and the positioning body 21. After the bumper body 1 and the positioning component 22 are positioned and assembled, the bumper body 1 is positioned and installed on the vehicle body 200. When the gap tolerance between the bumper body 1 and the hood is qualified, the bumper body 1 and the positioning body 21 can be fixedly connected by bolts to improve the connection strength of the bumper body 1. Furthermore, when the positioning component 22 needs to be switched to the adjustment state, the fastener stops limiting and fixing the positioning component 22, so that the positioning component 22 can move relative to the positioning body 21 in the front-rear direction X of the vehicle. With this setting, the positioning component 22 can be switched between the fastened state and the adjustment state by setting the first fastener 23. The adjustment method is relatively simple and convenient.

[0073] In some embodiments of this application, such as Figures 3-8 As shown, the positioning body 21 has a first mounting hole 212, and the positioning member 22 has a second mounting hole 222 corresponding to the first mounting hole 212. The size of the second mounting hole 222 is larger than the size of the first mounting hole 212 along the front-rear direction X of the vehicle. The positioning body 21 also has a nut 213, which is corresponding to the first mounting hole 212 along the height direction Z of the vehicle. The first fastener 23 is constructed as a bolt, which is adapted to pass through the second mounting hole 222 and the first mounting hole 212 to be tightened and fixed with the nut 213 to limit and fix the positioning member 22 to the positioning body 21. The bolt is also adapted to be loosened from the nut 213 so that the bolt stops limiting and fixing the positioning member 22.

[0074] Specifically, such as Figure 6 As shown, the first mounting hole 212 is constructed as a circular hole, as... Figure 7 As shown, the second mounting hole 222 is constructed as an elongated hole. Along the front-rear direction X of the vehicle, the size of the second mounting hole 222 is larger than the size of the first mounting hole 212. That is to say, the length of the elongated hole along the front-rear direction X of the vehicle is greater than the diameter of the circular hole. In order to ensure that the bumper body 1 can move at least ±3mm along the front-rear direction X of the vehicle, the clearance between the elongated hole and the circular hole on one side needs to be set at more than 3mm.

[0075] Furthermore, the nut 213 of the positioning body 21 can be constructed as a rivet nut, which is correspondingly set with the first mounting hole 212, and the part of the rivet nut is set on the side of the positioning body 21 away from the positioning member 22. The first fastener 23 is constructed as a bolt. When it is necessary to switch the positioning member 22 to the tightened state, the bolt is passed through the second mounting hole 222 and the first mounting hole 212 to be tightened and fixed with the rivet nut, so as to limit and fix the positioning member 22 to the positioning body 21. When it is necessary to switch the positioning member 22 to the adjustment state, the bolt is loosened from the rivet nut so that the bolt stops limiting and fixing the positioning member 22, thereby allowing the positioning member 22 to move relative to the positioning body 21 in the front-rear direction X of the vehicle.

[0076] Furthermore, to enable those skilled in the art to better understand this solution, as a specific example, during the installation of the bumper assembly 100, the positioning body 21 is fixedly installed on the vehicle body 200, and the positioning element 22 is installed on the positioning body 21. Optionally, the initial state of the positioning element 22 relative to the positioning body 21 is a tightened state. For example, such as... Figure 3 As shown, in the initial state, the bolt is passed through the second mounting hole 222 and the first mounting hole 212 to be tightened and fixed with the rivet nut, thereby fixing the positioning member 22 on the positioning body 21. During the installation of the bumper body 1, the positioning hole 11 and the positioning protrusion 221 are used to limit the movement of the bumper body 1 in the front-rear direction X of the vehicle.

[0077] After the bumper assembly 100 is installed, close the hood to measure the clearance tolerance between the bumper body 1 and the hood. If the clearance tolerance between the bumper body 1 and the hood is not up to standard, open the hood and loosen the bolts from the rivet nuts to switch the positioning component 22 to the adjustment state. The positioning component 22 can move relative to the positioning body 21. Then push and pull the bumper body 1 along the vehicle's front-rear direction X. It can be understood that because the positioning component 22 and the bumper body 1 are mutually limited in the vehicle's front-rear direction X, the bumper body 1 can drive the positioning component 22 to move relative to the positioning body 21 along the vehicle's front-rear direction X during the pushing and pulling process, so as to flexibly adjust the position of the bumper body 1. After the position of the bumper body 1 is adjusted, tighten the bolts to fix the positioning component 22 on the positioning body 21 again, so that the positioning component 22 is switched to the fastened state. Then close the hood and measure the clearance tolerance between the bumper body 1 and the hood again. If it is not up to standard, repeat the above steps to adjust until the clearance tolerance is up to standard.

[0078] Therefore, it is possible to flexibly adjust the position of the bumper body 1 along the front-rear direction X of the vehicle to achieve the optimal gap and surface difference between the bumper and the hood. Furthermore, the positioning component 22 can be switched between a fastened state and an adjusted state by tightening or loosening the bolts. The adjustment method is relatively simple and reliable. Moreover, the bolts are common standard parts, so there is no need to set up a special structure, which helps to reduce costs.

[0079] In some embodiments of this application, such as Figure 1 As shown, there are multiple positioning elements 22. That is, multiple positioning elements 22 can be provided on the positioning body 21. For example, the number of positioning elements 22 can be 2, 3, 4, or 5. Each positioning element 22 has both a fastened state and an adjusted state relative to the positioning body 21. Each positioning element 22 is used for positioning and assembly with the bumper body 1, so that each positioning element 22 can restrict the movement of the bumper body 1 along the vehicle's longitudinal direction X. This arrangement improves the positioning and assembly strength of the bumper body 1 when multiple positioning elements 22 are in the fastened state. When multiple positioning elements 22 are in the adjusted state, the positioning elements 22 can move relative to the positioning body 21 along the vehicle's longitudinal direction X. When the bumper body 1 is pushed or pulled along the vehicle's longitudinal direction X, multiple positioning elements 22 move simultaneously along the vehicle's longitudinal direction X, which helps improve the stability of the bumper body 1 during movement, thereby improving the adjustment accuracy of the bumper body.

[0080] In some embodiments of this application, multiple positioning elements 22 are arranged sequentially at intervals along the left-right direction Y of the vehicle. That is, multiple positioning elements 22 can be arranged sequentially at intervals along the left-right direction Y of the vehicle. It can be understood that the left-right direction Y of the vehicle is perpendicular to the front-back direction X of the vehicle. When multiple positioning elements 22 are all in the adjustment state, pushing or pulling the bumper body 1 along the front-back direction X of the vehicle causes multiple positioning elements 22 to move simultaneously along the front-back direction X of the vehicle. Since the arrangement direction of multiple positioning elements 22 is perpendicular to the movement direction, it is beneficial to ensure the consistency of the movement of multiple positioning elements 22, thereby improving the adjustment accuracy of the bumper body.

[0081] In some embodiments of this application, such as Figure 9 As shown, one of the multiple positioning elements 22 is also adapted to restrict the movement of the bumper body 1 along the left-right direction Y of the vehicle. That is, when there are multiple positioning elements 22, one of them can restrict the movement of the bumper body 1 both along the front-rear direction X and along the left-right direction Y of the vehicle, thus achieving dual restriction of the bumper body 1 in both the front-rear direction X and the left-right direction Y. For example, as... Figure 9As shown, when the positioning protrusion 221 of the positioning component 22 is inserted into the positioning hole 11 of the bumper body 1, the outer side wall of the positioning protrusion 221 abuts and is limited between the inner side wall of the positioning hole 11 along the front-rear direction X and the left-right direction Y of the vehicle. This setting can ensure the stability of the bumper body 1 during positioning and assembly, and also helps to improve the accuracy of the bumper body 1 during adjustment.

[0082] Secondly, embodiments of this application provide a vehicle 1000, including the bumper assembly 100 in the first aspect embodiment.

[0083] According to the vehicle 1000 proposed in the first aspect of this application, by providing the above-mentioned bumper assembly 100, when the positioning member 22 is in the adjustment state, the positioning member 22 and the bumper body 1 are positioned and assembled, and the position of the bumper body 1 along the front-rear direction X of the vehicle can be flexibly adjusted, so as to better control the gap tolerance between the bumper and the hood, so that the gap and surface difference between the bumper and the hood can be optimized, which is conducive to improving the overall appearance quality and refinement of the vehicle. Moreover, the adjustment method is simple and reliable, which is conducive to improving assembly efficiency and reducing assembly costs.
