[0030] As shown in Figures 1-5 An automobile bumper lower trim plate, comprising a lower trim plate main body 1, and a plurality of connecting pieces 2 arranged at the edges of the lower trim plate main body 1, the connecting piece 2 is a bending structure, comprising an edge connecting part 201 and a fastening connecting part 202, the back of the edge connecting part 201 is provided with a connecting groove 3, the connecting groove 3 extends to the back of the lower trim plate main body 1, a metal spring 4 is arranged in the connecting groove 3, the other end of the metal spring 4 extends to the back of the fastening connecting part 202 and is attached to the fastening connecting part 202.
[0031] The automobile bumper lower trim plate is improved by the connecting piece 2 arranged above, the metal spring 4 is added, so that the connecting part of the connecting piece 2 and the lower trim plate main body 1 and the bending part of the connecting piece 2 are not easy to break, the structural stability and service life of the connecting piece 2 can be improved, and the overall structure is not greatly changed compared with the original structure, so that the normal connection and use of the bumper lower trim plate are not affected, and the assembly and use are also convenient.
[0032] The edge connecting part 201 is connected with the lower trim plate main body 1, the fastening connecting part 202 is connected with the vehicle bumper or its accessory structure, so as to install and fix the whole lower trim plate under the rear bumper, the connecting piece is a force receiving piece while playing a connecting role, and the connecting part and the bending part are vulnerable and relatively weak parts, so the metal spring is designed to protect them.
[0033] The metal elastic sheet 4 has a shape similar to that of the connecting sheet 2, but the length of the lateral part of the metal elastic sheet 4 is longer than that of the edge decoration connecting part 201 of the connecting edge, and extends to the back of the lower decoration plate body 1, which corresponds to the support and lifting of the metal elastic sheet 4 on the back of the connecting sheet 2, so that the connecting sheet 2 is protected and shares the stress, especially the stress and support of the connecting part and the bending part, so as not to be easily damaged and broken; moreover, the metal elastic sheet 4 itself also has good flexibility and strong adaptability, and can better fit the connecting sheet without affecting the installation and fixation of the connecting sheet.
[0034] The thickness of the metal elastic sheet 4 is 0.1-1mm, preferably 0.5mm, which basically does not affect the installation of the connecting sheet, and does not increase much installation space.
[0035] The connecting groove 3 is provided to facilitate the plug-in installation of the metal elastic sheet 4, so that it can be inserted from the back to the front of the connecting groove and fit the back of the connecting sheet, and at the same time, the metal elastic sheet is positioned and limited.
[0036] The specific bending form of the connecting sheet 2 and the number of the connecting sheet arrangement are set according to the actual vehicle model, mainly depending on the structure of the rear bumper and its related accessories of different vehicle models, but the basic style and connecting structure are universal, and the lower decoration edge with the metal elastic sheet and the connecting groove can be widely used in many vehicle models.
[0037] Further, the cross section of the lower decoration plate body 1 is similar to a "C" shape structure, and in practice, it can also be other shapes, and the lower decoration plate body with different shapes is basically provided with a decoration edge, which is a kind of folding or covering structure; the edge of the upper decoration edge 101 is provided with a plurality of connecting sheets 2, the decoration edge connecting part 201 connects the upper decoration edge 101, and the connecting groove 3 extends inward along the back of the upper decoration edge 101.
[0038] Further, the decoration edge connecting part 201 and the extension line of the upper decoration edge 101 form an included angle of not more than 15°, and in general, the decoration edge connecting part 201 is a local extension of the upper decoration edge 101, and some are slightly upward.
[0039] The decoration edge connecting part 201 and the fastening connecting part 202 form an included angle of 80-120°, that is, the bending angle of the connecting sheet 2, most of which is more than 90° or 90 degrees, and a small part is less than 90°.
[0040] In some embodiments, the connecting groove 3 is a surrounding structure with a socket at one end. The connecting groove 3 of this structure has good surrounding performance and can cover the parts where the metal spring and the connecting part of the trim and the upper trim are attached.
[0041] In other embodiments, as shown in Figure 6 The connecting groove 3 includes a pair of L-shaped slots 301, and the two sides of the metal spring 4 are inserted into the pair of L-shaped slots 301. The connecting groove of this structure is a semi-open structure, which can also connect the metal spring 4, and the L-shaped slot 301 structure is easier to be integrated with the lower trim.
[0042] The connecting groove 3 of these two structures can be detached again after connecting the metal spring 4, and the metal spring can be recycled after the plastic part is damaged.
[0043] Further, the back of the fastening connecting part 202 is provided with an open limiting slot, which is arranged on both sides and can accommodate the bent vertical part of the metal spring 4 in the area between the limiting slots.
[0044] Further, the fastening connecting part 202 is provided with a connecting hole 5, and the metal spring 4 is also provided with a connecting hole 5 corresponding thereto. The connecting hole 5 can be connected with fasteners such as screws and bolts. Due to the arrangement of the metal spring, the back of the connecting piece does not need to be provided with a gasket, and the wear of the connecting piece by the fastener can be avoided.
[0045] Further, the lower trim body 1, the connecting piece 2 and the connecting groove 3 are integrally formed injection molded parts, that is, integrally formed plastic parts, which can be mass produced.
[0046] Further, the back of the lower trim body 1 is also provided with a plurality of transverse and longitudinal reinforcing ribs, which can improve the structural strength and stability of the lower trim body.
[0047] In some embodiments, as shown in Figure 7 The fastening connecting part 202 is provided with a recess 6, and the connecting hole 5 is arranged at the recess 6. The recess 6 is a small groove arranged in the middle of the fastening connecting part, which can be matched with the protruding structure of the connected part on the bumper and its attached structure, and can accommodate some small gaskets, which is beneficial to the connection and fixation of the connecting piece.
[0048] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
