[0002] An automobile bumper is a safety device that absorbs and buffers external impact forces and protects the vehicle body. From a safety perspective, it can play a buffering role when the vehicle has a collision accident and protect the safety of the vehicle body; from an aesthetic perspective, it can serve as a mounting base for other components and can also play a decorative role.

[0003] The bumper includes a front bumper located at the head of the vehicle body and a rear bumper located at the tail of the vehicle body. Taking the front bumper as an example, the connection of the bumper will be described.

[0004] The vehicle head generally includes a hood, fenders, headlights, a front bumper, and a bumper beam. Among them, there are two fenders and two headlights, which are symmetrically arranged with respect to the hood respectively. The hood, fenders, and front bumper can form an accommodation space, and the bumper beam is located on the inner side of the front bumper.

[0005] During the assembly process of the vehicle head, it is necessary to first place the front bumper on the bumper beam, that is, use the bumper beam to support the front bumper in the z-direction (the vehicle body height direction) to facilitate the assembly of the front bumper with other components; then, the front bumper is respectively snap-connected to the headlights on both sides to achieve the fixed connection between the front bumper and the headlights; and then the front bumper is snap-connected to the fenders to achieve the fixed connection between the front bumper and the fenders.

[0006] Since there may be machining errors and assembly errors in the fenders and headlights, etc., during the installation process of the vehicle head, it is necessary to manually adjust the position of the front bumper left and right (taking the left and right arrangement of the two headlights as an example), and at the same time rely on the deformation of the front bumper to achieve the connection between the front bumper and the headlights and fenders.

[0007] However, since there will be friction at the overlapping joint between the front bumper and the bumper beam during the left and right movement of the front bumper, there is wear on the front bumper and the bumper beam, and the weight of the front bumper is relatively large, making it difficult for the operator to drag the front bumper, and even more difficult to ensure the precise movement of the front bumper. Therefore, the assembly efficiency is greatly affected.

[0044] The present invention discloses a bumper assembly, which is convenient for adjusting the position of the bumper to improve the assembly efficiency. In addition, the present invention also discloses a front - end assembly and a vehicle having the above - mentioned bumper assembly.

[0045] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0046] Hereinafter, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0047] Such asFigure 1 As shown in the figure, the front-end assembly of the vehicle includes: a bumper main body 100, vehicle lights 200, fenders 300, and a hood 400.

[0048] Among them, the vehicle lights 200 include a left vehicle light and a right vehicle light, the fenders 300 include a left fender and a right fender, and the left vehicle light and the right vehicle light are distributed on both sides of the hood 400 and are symmetrically arranged; the left fender and the right fender are distributed on both sides of the hood 400 and are symmetrically arranged.

[0049] It should be noted that the connection line on both sides of the hood 400 is in the vehicle body width direction. Therefore, the connection mode of the left vehicle light and the right vehicle light, as well as the connection direction of the left fender and the right fender, are both in the vehicle body width direction.

[0050] One side of the bumper main body 100 is detachably connected to the left fender and the left vehicle light, and the other side of the bumper main body 100 is detachably connected to the right fender and the right vehicle light.

[0051] In some embodiments, the bumper main body 100 is respectively detachably connected to the left fender, the left vehicle light, the right fender, and the right vehicle light, including but not limited to snap connection. The hood 400, the fenders 300, and the bumper main body 100 can be combined to form a receiving space.

[0052] Combined with Figure 2 As shown in the figure, the vehicle further includes a bumper beam 500. The bumper beam 500 is located on the inner side of the bumper main body 100, and the bumper beam 500 is fixedly connected to the vehicle body.

[0053] During the assembly process of the front-end assembly of the vehicle, it is necessary to first place the bumper main body 100 on the bumper beam 500, that is, use the bumper beam 500 to support the bumper main body 100 in the z-direction (vehicle body height direction) to facilitate the assembly of the bumper main body 100 with other components; then, snap-connect the bumper main body 100 to the vehicle lights 200 on both sides respectively to realize the fixed connection between the bumper main body 100 and the vehicle lights 200; then, snap-connect the bumper main body 100 to the fenders 300 to realize the fixed connection between the bumper main body 100 and the fenders 300.

[0054] It should be noted that for the vehicle, the structure of the front-end assembly reflected in the above vehicle usually has components with the same functions as those at the front end at the rear end. Therefore, the structure of the rear-end assembly can also refer to the content of this article, and the rear-end assembly is also within the protection scope of this application.

[0055] During the left - right movement of the bumper main body 100, friction will occur at the overlapping part between the bumper main body 100 and the anti - collision beam 500, resulting in wear of the bumper main body 100 and the anti - collision beam 500. Moreover, since the weight of the bumper main body 100 is relatively large, it is very difficult for the operator to drag the bumper main body 100, and it is even more difficult to ensure that the bumper main body 100 moves accurately. Therefore, the assembly efficiency is greatly affected.

[0056] Based on this, combined with Figures 3 to 5 As shown, the present application discloses a bumper assembly, including a bumper main body 100 and an anti - collision beam 500.

[0057] Wherein, one side of the bumper main body 100 is used for detachably connecting with the left fender and the left headlight, and the other side of the bumper main body 100 is used for detachably connecting with the right fender and the right headlight. The anti - collision beam 500 is connected with the bumper main body 100 through a rolling component 600, and the bumper main body 100 can move relative to the anti - collision beam 500 in the vehicle body width direction.

[0058] In the present application, by connecting the bumper main body 100 and the anti - collision beam 500 with a rolling component 600, the position of the bumper main body 100 relative to the anti - collision beam 500 in the vehicle body width direction can be adjusted, that is, the left - right position of the bumper main body 100 can be adjusted, so as to facilitate the connection of the bumper main body 100 with the headlight 200 and the fender 300. Since the bumper main body 100 and the anti - collision beam 500 in the present application are in rolling connection, that is, the friction between the two is rolling friction, it is beneficial to reduce wear, and it is also convenient to reduce the labor intensity of the operation, facilitate the control of the position of the bumper main body 100, and improve the assembly efficiency of the bumper main body 100.

[0059] As Figures 6 to 8 shown, the above - mentioned rolling component 600 includes: a guide rail 623 and a roller 612.

[0060] Wherein, one of the anti - collision beam 500 and the bumper main body 100 has a guide rail 623, and the other has a roller 612. Specifically, the guide rail 623 is arranged in the vehicle body width direction, and the roller 612 is installed on the bumper main body 100 through a roller shaft 614 and can roll along the guide rail 623.

[0061] By the roller 612 rolling along the guide rail 623, the movement of the bumper main body 100 relative to the anti - collision beam 500 can be realized.

[0062] For the shapes and arrangement positions of the guide rail 623 and the roller 612, they can be set according to different needs, and are all within the protection scope.

[0063] In some embodiments, the rolling component 600 further includes: a support plate 621, a base 611, a first connecting piece 622 and a second connecting piece 613.

[0064] Among them, the support plate 621 is detachably connected to the anti-collision beam 500, and the support plate 621 is provided with a guide rail 623. The shape and size of the support plate 621 can be set according to different needs.

[0065] In this application, the support plate 621 includes but is not limited to being detachably connected to the anti-collision beam 500 through a first connecting member 622, and the first connecting member 622 can be a screw. The support plate 621 can also be bonded to the anti-collision beam 500.

[0066] The base 611 is detachably connected to the bumper main body 100, and a rotatable roller 612 is installed on the base 611.

[0067] In this application, the base 611 includes but is not limited to being detachably connected to the bumper main body 100 through a second connecting member 613, and the second connecting member 613 can be a screw. The base 611 can also be bonded to the bumper main body 100.

[0068] In this application, in order to achieve the rolling connection between the bumper main body 100 and the anti-collision beam 500, by adding the support plate 621 and the base 611, the guide rail 623 and the roller 612 are respectively set, so that the original structure of the bumper main body 100 and the anti-collision beam 500 will not be changed, thereby reducing the R & D cost.

[0069] The above discloses a method of setting the roller 612 on the bumper main body 100 and setting the guide rail 623 on the anti-collision beam 500. Of course, the roller 612 can also be set on the anti-collision beam 500, and the guide rail 623 can be set on the bumper main body 100, and it is also within the protection scope.

[0070] See Figure 7 As shown, in some embodiments, the guide rail 623 is a groove formed on the support plate 621, and the longitudinal section of the groove is V-shaped.

[0071] Adopting the guide rail 623 in the form of a groove, the roller 612 can be accommodated in the groove, and the groove is used to guide the rolling direction of the roller 612 and limit the axial direction of the roller 612.

[0072] In some embodiments, the above-mentioned guide rail 623 can also be a rack structure, and the roller 612 is a gear structure capable of meshing with the rack.

[0073] The longitudinal section of the groove is V-shaped, which can make the side of the groove bottom to the groove opening inclined, and can prevent the side of the groove from rubbing against the roller 612 and affecting the normal rolling of the roller 612.

[0074] It should be noted that the shape and size of the groove can be set according to different needs, including but not limited to the above-disclosed content.

[0075] Combined Figure 6 As shown, the above-mentioned support plate 621 includes: a connecting section 6211 and a supporting section 6212.

[0076] Among them, the connecting section 6211 is in contact with the anti-collision beam 500, and the connecting section 6211 has a recessed portion 6213 that is recessed away from the anti-collision beam 500. A threaded hole is provided in the recessed portion 6213. The first connecting member 622 is connected to the anti-collision beam 500 through the threaded hole, and a buffer gasket is provided between the recessed portion 6213 and the anti-collision beam 500.

[0077] The supporting section 6212 is connected to the connecting section 6211. In some embodiments, the supporting section 6212 and the connecting section 6211 include but are not limited to being integrally formed. The supporting section 6212 extends away from the anti-collision beam 500, and the supporting section 6212 has a guide rail 623.

[0078] By adding a buffer gasket, the transmission of vibration can be reduced, thereby reducing noise pollution.

[0079] The shape of the support plate 621 can also be other shapes and structures, which can be set according to different needs and are all within the protection scope.

[0080] Figure 6 The side of the base 611 in [[ ]] close to the support plate 621 has an avoidance groove 6112 that is recessed away from the support plate 621. A connection hole is provided in the avoidance groove 6112. The second connecting member 613 is connected to the bumper main body 100 through the connection hole, and the second connecting member 613 is hidden in the avoidance groove 6112.

[0081] The avoidance groove 6112 in this application can hide the second connecting member 613, thereby avoiding interference between the second connecting member 613 and the support plate 621 after the installation process.

[0082] Such as Figure 8 As shown, there are at least two rollers 612 in this application, and the distance between the rollers 612 at both ends is less than the length of the guide rail 623. By increasing or decreasing the number of rollers 612, the gravity borne by each roller 612 can be increased, and the increase in the number of rollers 612 can also ensure the stability of the bumper main body 100 during the moving process, which is beneficial to preventing the problem of deviation.

[0083] The number of the rolling components 600 includes but is not limited to one, and the rolling components 600 include but are not limited to being installed at the middle position of the bumper main body 100 along the vehicle body width direction.

[0084] In some embodiments, there are three rolling components 600, and they are evenly arranged along the vehicle body width direction of the bumper main body 100.

[0085] In addition, a front-end assembly is also disclosed in the present application, which includes a hood 400, fenders 300, headlamps 200, and a bumper assembly. Among them, the bumper assembly is the bumper assembly disclosed in the above embodiments, and the fenders 300 and headlamps 200 refer to the above content. Therefore, the front-end assembly with this bumper assembly also has all the above technical effects, which will not be elaborated one by one here.

[0086] In addition, a vehicle is also disclosed in the embodiments of the present invention, which includes the front-end assembly disclosed in the above embodiments.
