[0002] With the gradual improvement of existing automobile lighting effects, people pay more attention to the beauty of automobile lights. The existing headlight frames, which mainly play a decorative role, are generally fixed on the large shell of the car, and the light-emitting lamp body of the car is surrounded and installed on the inner side of the headlight frame. In order to achieve beautiful appearance, the existing headlight frames usually design decorative parts of different colors on the headlight frames. At the same time, as an important part of automobile lights, the headlight frames are made into an integral structure by adopting two-color injection molding or multi-color injection molding to avoid the shaking of the headlight frames during use.

DETAILED DESCRIPTION

[0036] The present invention will be further described below in conjunction with the accompanying drawings:

[0037] See attached Figure 1-Figure 15: In order to make the headlight frame more beautiful and convenient for installing the internal lamp body structure, this embodiment discloses a headlight frame installation structure, including a frame body 1, the frame body 1 includes a light source installation area 1-1 for installing a light source and a side reflection area 1-2 arranged outside the light source installation area 1-1 and gradually bent backward and extended, the light source installation area 1-1 and the side reflection area 1-2 are integrally formed; the headlight frame in this embodiment is the right headlight frame of the car, and in this embodiment, the side of the light emitting direction of the headlight is the front end, and the opposite side is the rear end; specifically, in this embodiment, a main light frame 2 for installing a light source is provided in the light source installation area 1-1, and a plurality of secondary light frames 3 are provided on the upper end of the main light frame 2, which are arranged on the frame body 1 from the inside to the outside in sequence, such as Figure 1 As shown, the secondary lamp frame 3 is arranged at the upper end of the main lamp frame 2; when the automobile lamp is actually assembled, the lamp body of the automobile lamp is mainly installed in the main lamp frame 2 and the secondary lamp frame 3; wherein, in this embodiment, in order to make the decorative frame more three-dimensional, a protrusion 4 protruding from the side reflection area 1-2 and connected to the secondary lamp frame 3 is provided on the outer end surface of the side reflection area 1-2. In order to avoid affecting the forward light emitting effect of the automobile lamp, the protrusion 4 in this embodiment is arranged on the right side of the right lamp decorative frame, and the protrusion 4 is integrally formed with the side reflection area 1-2. The decorative frame is more beautiful and has a sense of hierarchy. In this embodiment, a first decorative sheet 5 covering the raised portion 4 is provided on the outer side of the raised portion 4. In this embodiment, in order to make the three-dimensional sense of the headlight more obvious, the first decorative sheet 5 and the raised portion 4 are different colors, so that the structural design of the first decorative sheet 5 and the decorative frame body 1 in this embodiment cannot be realized by a simple injection molding device; the first decorative sheet 5 and the decorative frame body 1 in this embodiment are designed as separate bodies, so that the first decorative sheet 5 is fixedly connected to the raised portion 4 by hot riveting; specifically, as Figure 2 , Figure 3 and Figure 5As shown, a mounting groove 6 connected to the protruding portion 4 is provided on the side reflection area 1-2. In this embodiment, there are two groups of mounting grooves 6, which are respectively arranged on the upper and lower sides of the protruding portion 4 and connected to the upper and lower walls of the protruding portion 4. A first pin hole 7 penetrating the mounting groove 6 from front to back is provided at the bottom of the mounting groove 6. A connecting portion 8 extending into the mounting groove 6 is provided on the first decorative piece 5. A first pin 9 penetrating into the first pin hole 7 and protruding from the inner end surface of the side reflection area 1-2 is provided on the connecting portion 8. In this embodiment, in order to facilitate hot riveting of the pins, the first pin holes 7 on the same mounting groove 6 are arranged at a certain distance from each other, and the first pin holes 7 on the upper and lower mounting grooves 6 are staggered with each other; during installation and assembly, the first decorative piece 5 covers the outer side of the protruding portion 4 from front to back and the first pin 9 is inserted into the first pin hole 7, and then the first pin 9 protruding from the first pin hole is riveted by a hot riveting device. 7 can be hot-riveted; at the same time, in this embodiment, the position on the inner end surface of the side reflection area 1-2 opposite to the mounting groove 6 is protruded outward, so that the hot riveting position is more protruding relative to the inner end surface of the reflection area 1-2, thereby avoiding the hot riveting equipment from contacting other parts of the side reflection area 1-2 during hot riveting, and at the same time, it can also ensure that the thickness at the mounting groove 6 is the same as the thickness of the side reflection area 1-2, thereby avoiding the occurrence of defects such as pores and cracks in the decorative frame body 1 during plastic forming; in this embodiment, in order to block part of the lateral light of the lamp body and avoid lateral light leakage, a second decorative piece groove 10 connected to the main light frame 2 is opened on the side reflection area 1-2, and a second decorative piece 12 is arranged in the second decorative piece groove 10. In order to avoid affecting the forward light emitting effect of the lamp, the second decorative piece 12 is also arranged on the right side of the main light frame 2 at a position connected to the main light frame 2; specifically, as Figure 1 , Figure 2 , Figure 4 and Fig. 9 As shown, in this embodiment, a second pin hole 11 penetrating through the decorative frame body 1 is provided at the bottom of the second decorative piece groove 10, and a second pin 13 penetrating through the second pin hole 11 and protruding out of the inner end surface of the side reflection area 1-2 is provided on the second decorative piece 12; specifically, the first pin 9 and the second pin 13 in this embodiment are arranged in parallel and in the same direction, so as to facilitate the simultaneous hot riveting process of the first pin 9 and the second pin 13; at the same time, in order to block the lateral light of the lamp body in the main lamp frame 2, in this embodiment, a shielding portion 14 penetrating through the main lamp frame 2 and extending backward is fixedly connected to the second decorative piece 12 on one side close to the main lamp frame 2; specifically, as Figure 2 , Figure 6 and Figure 7As shown, the shielding portion 14 in this embodiment includes a connecting portion 14-1 located in the main light frame 2 and connected to the second decorative piece 12, and a limiting installation portion 14-2 connected to the connecting portion 14-1 and extending obliquely toward the inner end surface of the side reflection area 1-2. In this embodiment, the limiting installation portion 14-2 extends obliquely toward the right rear from one side of the connecting portion 14-1, and the extension direction of the limiting installation portion 14-2 is the same as the installation direction of the lamp body, thereby facilitating the installation of the lamp body in the main light frame 2 and after the lamp body is installed, the limiting installation portion 14-2 fits with the side wall of the lamp body to achieve shielding of the lateral light of the lamp body; as shown in FIG. Figure 6 As shown, in order to completely block the side of the main light frame 2 and facilitate the injection molding of the second decorative piece 12, the second decorative piece 12 in this embodiment includes a decorative piece main body 12-1 extending from the light source installation area 1-1 to the side reflection area 1-2, an upper edging 12-2 arranged on the upper left side of the decorative piece main body 12-1 and corresponding to the side of the main light frame 2, and a lower edging 12-3 arranged on the lower left side of the decorative piece main body 12-1 and corresponding to the side of the main light frame 2, and the shielding portion 14 is connected to the decorative piece main body 12-1, the upper edging 12-2 and the lower edging 12-3, respectively.

[0038] like Figure 8 and Fig. 9As shown, in order to ensure that the second decorative piece 12 is firmly fixed to the decorative frame body 1, it is necessary to provide pins connected to the decorative frame body 1 on all sides of the second decorative piece 12. In this embodiment, a limiting mounting portion 14-2 is provided close to the inner end surface of the side reflection area 1-2, so that the portion of the rear end surface of the side reflection area 1-2 corresponding to the limiting mounting portion 14-2 is blocked in the vertical direction. If a second pin 13 in the same direction as the first pin 9 is also provided on the rear end surface of the side reflection area 1-2 corresponding to the limiting mounting portion 14-2, the second pin 13 cannot be hot-riveted. In this embodiment, in order to achieve a fixed connection between the portion of the second decorative piece 12 corresponding to the blocking portion 14 and the decorative frame body 1, a hot riveting cavity 15 with a lateral opening is provided between the limiting mounting portion 14-2 and the inner end surface of the side reflection area 1-2. As shown in the lamp frame, the opening on the hot riveting cavity 15 is set to the right rear, the side reflection area 1-2 is provided with a side pin hole 16 set towards the opening of the hot riveting cavity 15, and the second decorative piece 12 is provided with a side pin 17 inserted into the side pin hole 16 and protruding from the inner end surface of the side reflection area 1-2, and then during installation, the hot riveting device can perform hot riveting on the side pin 17 through the side opening of the hot riveting cavity 15 when hot riveting the second decorative piece 12 corresponding to the shielding portion 14, thereby ensuring that the second decorative piece 12 is firmly fixed. At the same time, in order to facilitate the installation of the first pin 9, the second pin 13 and the side pin 17, in this embodiment, the first pin 9, the second pin 13 and the side pin 17 are wedge-shaped structures that are gradually reduced from the inside to the outside, and then during assembly, the small head end of the outer side of the pin is first inserted into the pin hole, thereby facilitating the corresponding installation of the pin and the pin hole;

[0039] This embodiment also discloses a method for processing the above-mentioned vehicle lamp frame installation structure, including the following steps:

[0040] Step 1: Move the first decorative piece 5 from front to back to cover and install it on the outside of the raised portion 4 and make the first pin 9 correspondingly inserted into the first pin hole 7, then put the second decorative piece 12 into the main light frame 2, so that the second decorative piece 12 moves from the side to the side reflection area 1-2, so that the direction of the side pin 17 corresponds to the direction of the side pin hole 16, and during the movement, the second pin 13 contacts the front end surface of the second decorative piece groove 10 and slides on the front end surface of the second decorative piece groove 10 until the side pin 17 is completely inserted into the side pin hole 16, and at this time, the second pin 13 is also completely inserted into the second pin hole 11; the positioning mold 20 on the hot riveting device is pushed outward horizontally through the displacement device, and then the side reflection area 1-2 is horizontally set and the inner end surface of the side reflection area 1-2 is fixed on the positioning mold 20 with the inner end surface facing upward, and the fixing device 21 on the hot riveting device fixes the positioning mold 20 so that the first pin 9 and the second pin 13 are set vertically upward;

[0041] Step 2: Start the hot riveting device. The hot riveting head 55 located above the first pin 9 and the second pin 13 on the hot riveting device moves downward under the action of the driving device and contacts the first pin 9 and the second pin 13 respectively, so as to perform hot riveting on the first pin 9 and the second pin 13. The hot riveting head 55 heats and melts the first pin 9 and the second pin 13 so that the pins are limitedly covered on the outside of the pin holes after melting, so as to achieve a fixed connection between the decorative sheet and the decorative frame body 1. After the hot riveting is completed, the corresponding hot riveting head 55 moves upward to the original position under the action of the driving device.

[0042] Step 3: The fixing device 21 releases the fixing of the positioning mold 20, and then the positioning mold 20 is driven by the rotating driving device 24 to drive the decorative frame body 1 to rotate counterclockwise, so that the opening of the hot riveting cavity 15 faces upward and the lateral pin 17 is vertically arranged upward, and the fixing device 21 fixes the rotated positioning mold 20 again, thereby limiting the rotation of the positioning mold 20 to reposition the rotated positioning mold 20, and then the hot riveting head 55 located above the lateral pin 17 on the hot riveting device moves downward under the action of the driving device and contacts the lateral pin 17, and similarly, the hot riveting head 55 performs hot riveting on the lateral pin 17; after the hot riveting is completed, the corresponding hot riveting head 55 moves upward to the original position under the action of the driving device;

[0043] Step 4: The positioning mold 20 on the hot riveting equipment is pushed out horizontally through the displacement device, and the hot-riveted decorative frame body 1 is taken out and the above steps are repeated.

[0044] like Fig.10 As shown, the hot riveting equipment in this embodiment includes a frame 18, a workbench 19 arranged on the frame 18, a sliding platform 22 slidably connected to the workbench 19 for installing a positioning mold 20 and a fixing device 21, and a clamping device arranged on the positioning mold 20 to fix the decorative frame body 1, and a rotating drive device 24 is fixedly connected to the sliding platform 22 for driving the positioning mold 20 to rotate; specifically, the hot riveting head 55 in this embodiment is an existing hot riveting head 55 heated by high frequency, and a linear guide rail that can move forward and backward is arranged on the workbench 19, and the sliding platform 22 is installed on the upper end of the linear guide rail. A screw module for driving the sliding platform 22 to move forward and backward is provided on the workbench 19, and then the sliding platform 22 is driven by the screw module to move forward and backward to form a displacement device that drives the positioning mold 20 to move forward and backward, so that it is more convenient to place the decorative frame body 1; specifically, as Fig.10 and Fig.11As shown, the fixing device 21 in this embodiment includes a rotating support seat 25 arranged on the front and rear sides of the upper end of the sliding platform 22, the positioning mold 20 is rotatably connected between the rotating support seats 25, the positioning mold 20 is provided with a positioning portion 27, and the rotating support seat 25 is provided with a limiting portion 28 for limiting the rotation of the positioning portion 27; wherein the positioning portion 27 includes a vertical positioning portion 27-1 and a side positioning portion 27-2 arranged on the lower end surface of the positioning mold 20, and the vertical positioning portion 27-1 and the side positioning portion 27-2 are both provided with a rotating positioning hole 29, and the limiting portion 28 includes a telescopic cylinder 30 installed on the rotating support seat 25, and when the positioning mold 20 is not rotating, the piston end of the telescopic cylinder 30 extends out and is inserted into the rotating positioning hole 29 on the vertical positioning portion 27-1. When the positioning mold 20 needs to be rotated to perform hot riveting on the lateral pin 17, the piston end of the telescopic cylinder 30 retracts and disengages from the rotation positioning hole 29 on the vertical positioning portion 27-1, and then the rotary drive device 24 rotates to drive the positioning mold 20 to rotate a certain angle and then stops. At this time, the rotation positioning hole 29 on the rotation of the side positioning portion 27-2 just rotates to the position of the rotation positioning hole 29 on the original vertical positioning portion 27-1. Finally, the piston end of the telescopic cylinder 30 extends out and inserts into the rotation positioning hole 29 on the side positioning portion 27-2 to limit the positioning portion 27 and the positioning mold 20, so that the rotated positioning mold 20 is locked in the state where the lateral pin 17 is in the vertical position, thereby facilitating the hot riveting head 55 to hot rivet the lateral pin 17.
