[0031] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described below are some embodiments of the present utility model, not all embodiments.

[0032] As shown in the Figure 1 accompanying drawings, the decorative strip fixing structure of the present utility model includes a decorative strip 100 and a mating part 200.

[0033] In the automotive industry, a mating part refers to a part or component that cooperates with and corresponds to the current part or component, and this cooperation relationship may involve multiple aspects such as assembly, connection, and function realization. In the present utility model, the mating part 200 refers to the vehicle component corresponding to the installation position of the decorative strip 100. In this embodiment, the mating part 200 is taken as the radiator grille of the vehicle, and the decorative strip 100 is taken as the logo decorative strip 100 of the vehicle as an example.

[0034] The decorative strip 100 has a first connection end 121 and a second connection end 111, and the mating part 200 has a first connection portion 221 and a second connection portion 211.

[0035] The first connection end 121 is connected to the first connection portion 221, and the second connection end 111 is connected to the second connection portion 211 to realize the installation and fixation of the decorative strip 100 and the mating part 200.

[0036] Specifically: the first connection end 121 is in the shape of a spherical body, and the first connection end 121 is provided on the side of the decorative strip 100 facing the mating part 200. The first connection portion 221 is in the shape of a spherical groove, and the first connection portion 221 has a bayonet 222 that opens towards the decorative strip 100. The first connection end 121 is movably embedded in the first connection portion 221.

[0037] As Figure 5 shown, the second connection end 111 is a through hole, and a connecting bolt 130 is passed through the second connection end 111, and the connecting bolt 130 is connected to the second connection portion 211.

[0038] When installing and fixing the decorative strip 100 to the mating part 200, first embed the first connection end 121 into the first connection portion 221 through the bayonet 222, and then lock and connect the second connection end 111 and the second connection portion 211 through the connection bolt 130. Since there is a certain gap between the first connection end 121 and the first connection portion 221, and the second connection end 111 is a through hole, before the connection bolt 130 is locked and fixed, the second connection end 111 can move relative to the connection bolt 130 within a certain range. Before the first connection end 121 is embedded into the first connection portion 221 and the connection bolt 130 locks the second connection end 111 and the second connection portion 211, the decorative strip 100 can be finely adjusted according to the installation position, so that the decorative effect can match other decorative parts and achieve the optimal appearance effect.

[0039] In this embodiment, the mating part 200 is the radiator grille of a vehicle and has a certain thickness. The second connection portion 211 is a threaded hole corresponding to the connection bolt 130. The connection bolt 130 passes through the second connection end 111 and is threadedly connected to the second connection portion 211. In some other embodiments, when the mating part 200 is a sheet metal part with a relatively thin thickness, the second connection portion 211 can be configured as a through hole, and a nut is provided on the side of the second connection portion 211 away from the decorative strip 100. The connection bolt 130 passes through the second connection end 111 and the second connection portion 211 and is connected to the nut.

[0040] In this embodiment, the decorative strip 100 and the mating part 200 are arranged front and back, and the decorative strip 100 is arranged on the front side of the mating part 200.

[0041] In this embodiment, the projection of the decorative strip 100 in the front-back direction is a long strip extending up and down. The first connection end 121 is arranged at the lower end of the decorative strip 100, and the second connection end 111 is arranged at the upper end of the decorative strip 100. Correspondingly, the second connection portion 211 and the first connection portion 221 are arranged up and down.

[0042] Furthermore, the middle part of the decorative strip 100 in this embodiment is snap-connected to the mating part 200. There is a slot extending up and down between the first connection portion 221 and the second connection portion 211 of the mating part 200, and the middle part of the decorative strip 100 is embedded in the slot. The mating part 200 and the middle part of the decorative strip 100 can be snap-connected through an existing connection structure, which will not be described in detail here.

[0043] The first connection end 121 of this embodiment and the decorative strip 100 are of a split structure. Referring to FIGS. 3 and 5, the decorative strip 100 includes: a strip body 110 and a connecting ball post 120. The first connection end 121 is provided at the rear end of the connecting ball post 120, and the front end of the connecting ball post 120 is fixedly connected to the strip body 110.

[0044] Specifically, the front end of the connecting ball post 120 is in a cylindrical shape, and the strip body 110 is provided with a corresponding cylindrical hole groove. The front end of the connecting ball post 120 is inserted into the hole groove. The front end of the connecting ball post 120 and the hole groove can be fixedly connected by interference fit or screw connection.

[0045] The outer side of the middle part of the connecting ball post 120 has a limiting flange 122. The limiting flange 122 is in a disc shape. The front side of the limiting flange 122 abuts against the front end of the hole groove to realize the positioning and installation of the connecting ball post 120 relative to the strip body 110.

[0046] The first connecting part 221 of this embodiment and the counter member 200 are of a split structure. As Figure 6 shown, the counter member 200 includes: a base body 210 and a ball head support 220. The first connecting part 221 is provided on the ball head support 220. The bayonet 222 is provided at the front end of the ball head support 220, and the rear end of the ball head support 220 is fixedly connected to the base body 210.

[0047] The ball head support 220 of this embodiment is in a cylindrical tube shape, and the central axis of the ball head support 220 extends in the front-rear direction. The first connecting part 221 is provided in the middle of the ball head support 220, and the bayonet 222 is provided at the front end of the ball head support 220.

[0048] The rear end of the ball head support 220 has a through hole that penetrates through the front and rear, and a mounting screw 230 is inserted through the rear end of the ball head support 220. The mounting screw 230 passes through the rear end of the ball head support 220 and is threadedly connected to the base body 210.

[0049] Four outwardly protruding positioning parts 225 are evenly distributed on the outer side of the rear end of the ball head support 220 of this embodiment. The base body 210 has positioning grooves corresponding to the positioning parts 225 one by one. During the installation of the ball head support 220, first embed the positioning parts 225 into the positioning grooves. When the mounting screw 230 is rotated, the positioning parts 225 being stuck in the positioning grooves can prevent the ball head support 220 from rotating relative to the base body 210, thereby locking and fixing the ball head support 220 on the base body 210.

[0050] In this embodiment, the decorative strip 100 is made of ABS material, and the ball support 220 is made of PA66-GF30. ABS refers to acrylonitrile-butadiene-styrene copolymer, a thermoplastic polymer structural material. PA66-GF30 is the general designation for PA66 plastic material with 30% glass fiber, characterized by high strength, water resistance, good wear resistance, and excellent heat resistance.

[0051] The bayonet 222 of this embodiment is wide at the front and narrow at the back. During the installation of the decorative strip 100 and the counterpart 200, the bayonet 222 facilitates alignment of the first connecting end 121. The first connecting end 121 opens the bayonet 222 and snaps into the first connecting portion 221, thus achieving a ball-jointed connection between the decorative strip 100 and the counterpart 200.

[0052] When the first connecting end 121 is inserted into the first connecting portion 221, the retaining ring 222 is stretched and elastically deformed. After the first connecting end 121 is inserted into the first connecting portion 221, the rear end of the retaining ring 222 can restrain the first connecting end 121 within the first connecting portion 221. The ball support 220 of this embodiment has an opening slot 223 and a through slot 224. The opening slot 223 and the through slot 224 extend in mutually perpendicular radial directions and both pass through the ball support 220.

[0053] Reference Figure 7 The front end of the opening slot 223 is open, dividing the front end of the ball support 220 into two symmetrical parts. When the first connecting end 121 is engaged with the first connecting portion 221 through the bayonet 222, the two symmetrical parts of the bayonet 222 are spread apart and away from each other. The through slot 224 penetrates both symmetrical parts of the ball support 220, reducing rigidity and making it easier for the bayonet 222 to be spread apart.

[0054] This embodiment also provides a vehicle, including the above-mentioned decorative strip fixing structure.

[0055] The vehicle can be a private car, such as a sedan, SUV, MPV, or pickup truck. It can also be a commercial vehicle, such as a van, bus, small truck, or large trailer. The vehicle must have an electric motor that can output power or store mechanical energy as a generator. If the vehicle is a new energy vehicle, it can be a hybrid or a pure electric vehicle.

[0056] The decorative strip 100 can be a decorative piece at any position of the vehicle, and the counterpart 200 is a vehicle component corresponding to the installation position of the decorative strip 100 .

[0057] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments, and various changes can be made without departing from the gist of the present utility model within the scope of knowledge possessed by those of ordinary skill in the relevant art.
