[0002] The integrated reflector products in the existing reflectors have poor consistency, which easily leads to deformation of the light type and unqualified light distribution. Therefore, the high and low beam reflectors are now designed separately, and the reflectors are adjusted in advance. The existing reflectors are all adjusted with a ball head seat and a ball head screw. For example, the patent application number CN201610390519.4 is a reflective high and low beam combination lamp structure for motorcycles with an LED light source, which includes a heat dissipation aluminum seat, a high beam reflector assembly fixedly connected to the top of the heat dissipation aluminum seat, a low beam reflector assembly fixedly connected to the bottom of the heat dissipation aluminum seat, two connecting brackets connected to the upper part of the rear end of the heat dissipation aluminum seat, and an adjustment mechanism connected to the lower part of the rear end of the heat dissipation aluminum seat; the connecting bracket components in the above patent are relatively more and the structure is relatively complex. When installing the ball head, the ball head seat component needs to be installed to further limit the ball head. There are relatively more process steps during assembly, and the assembly is troublesome; at the same time, the adjustment mechanism structure is also composed of multiple components, and the installation of the adjustment mechanism during assembly is also more troublesome, which is not convenient for the efficient production of the lamp. Summary of the invention

[0003] The present invention aims to solve the problems existing in the above-mentioned prior art and provides a vehicle lamp installation structure capable of pre-adjusting a reflector. The installation structure is relatively simple and easy to assemble, which can relatively reduce the number of assembly steps, thereby facilitating improving vehicle lamp processing efficiency and reducing vehicle lamp manufacturing costs.

The adjusting movement of the adjusting part drives the reflector to rotate relative to the rotating slot for angular adjustment in the corresponding direction, so that the reflector and the headlight mounting seat are clamped by the relatively rotatable limiting buckle and the rotating slot, so that the pre-adjustment installation of the reflector is more convenient and quick.

During installation, the rotating portion squeezes the elastic clamping portion so that the elastic clamping portion deforms outwardly, thereby expanding the deformation channel and allowing the rotating portion to enter the arc-shaped accommodating groove through the deformation channel. After the rotating portion disengages from the deformation channel, the elastic clamping portion resets and thereby limits the rotating portion from escaping outward. The installation and clamping limit of the limit clip are achieved through the elastic deformation of the elastic clamping portion, thereby making the installation of the limit clip more convenient and also making the limit clip firmly fixed after installation.

[0007] Preferably, an installation space for the adjusting screw to pass through is provided between the deforming pins, and an inclined deformation surface that deforms inwardly and contacts the adjusting screw is provided on the side of the deforming pin facing the installation space. When the adjusting screw passes through the installation space, the adjusting screw contacts the inclined deformation surface and squeezes the deforming pin outward, causing the deforming pin to deform outward so that the inner limit protrusion on the deforming pin is limited on the inner side surface of the mounting plate.

[0008] Preferably, a rotating hole for the adjusting screw to pass through is provided on the headlight mounting seat, and a limiting boss is provided on the outer side of the rotating hole and is arranged on the outer side surface of the headlight mounting seat for limiting the nut end of the adjusting screw.

A transverse limiting portion is provided, and after the limiting buckle is inserted into the limiting slot, the transverse limiting portion just contacts the limiting plane for limiting, so that the reflector is limited in the left and right directions after installation, thereby making the installation positioning accuracy of the reflector higher.

[0010] Preferably, a first arc-shaped contact surface is provided on the side where the inner limit protrusion contacts the surface of the mounting plate, and the second arc-shaped contact surface is provided on the side where the outer limit protrusion contacts the surface of the mounting plate, and the curvature of the first arc-shaped contact surface is the same as that of the second arc-shaped contact surface.

[0013] Preferably, a method for installing a vehicle lamp mounting structure capable of pre-adjusting a reflector comprises the following steps: S1: Insert the adjusting screw into the rotating hole from the back to the front, so that the nut end of the adjusting screw contacts the limiting boss on the outer side of the lamp mounting seat, and then put the inner limiting part on the adjusting screw at one end of the inner side of the lamp mounting seat; S2: Insert the driving part into the mounting hole from the back to the front, so that the elastic clamping part is arranged in the upper and lower positions; S3: Move the reflector from front to back, insert the rotating part at the rear end of the reflector into the deformation channel, and when moving backward, the rotating part causes the elastic deformation plate to bend and deform outward, thereby making the deformation channel larger to facilitate the passage of the rotating part, and after the rotating part leaves the deformation channel and enters the arc-shaped receiving groove, the elastic clamping part returns to its original position, thereby preventing the rotating part from escaping outward; S4: moving the limiting contact part so that the limiting contact part on the inner limiting part contacts the inner side surface of the lamp mounting seat and the inner end of the clamping inclined part is clamped into the limiting clamping groove of the adjusting screw to achieve the positioning installation of the adjusting screw, so that the position of the adjusting screw relative to the lamp mounting seat is fixed and the adjusting screw can be rotated relative to the lamp mounting seat; S5: While fixing the reflector, rotate the adjusting screw so that the front end of the adjusting screw rotates into the outer limit portion through the thread, and continue to rotate the adjusting screw so that the front end of the adjusting screw enters the installation space and contacts and squeezes the inclined deformation surface. Under the action of the inclined deformation surface, the deformation pin is deformed outward and contacts the mounting plate, and then the inner limit protrusion on the deformation pin is limited on the inner side surface of the mounting plate after the outward deformation.

[0014] The beneficial effects of the present invention are as follows: the present invention is provided with a reflector and a lamp mounting seat which are connected by a rotating slot and a limiting buckle; during assembly, the elastic deformation plate is deformed outwardly under the action of the limiting buckle, thereby increasing the spacing space to facilitate the limiting buckle to enter the arc-shaped accommodating groove through the deformation channel, thereby facilitating assembly; at the same time, a driving part formed by an external limiting part, a deforming bayonet and an internal limiting protrusion is provided, so that the adjustment mechanism components of the reflector are reduced, and the installation is convenient, thereby further shortening the assembly time of the lamp and improving production efficiency.

DETAILED DESCRIPTION

[0017] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0018] See attached Figure 1 As shown: the present embodiment discloses a headlight mounting structure capable of pre-adjusting a reflector, comprising a reflector 1 and a headlight mounting seat 2 for mounting the reflector 1, the reflector 1 being used to reflect light toward the front of the headlight; in order to ensure the consistency of the product and the good light pattern in the present application, the reflector 1 is rotatably connected to the headlight mounting seat 2 in the present application to adjust the direction of the reflected light after being reflected by the reflector 1; specifically, a rotation slot 3 is provided on the headlight mounting seat 2 in the present embodiment, and a limit buckle 4 is provided on the reflector 1, which is clamped in the rotation slot 3 and can rotate relative to the rotation slot 3; at the same time, in the present embodiment, an adjustment portion 5 is provided on the headlight mounting seat 2, which can be adjusted and moved relative to the headlight mounting seat 2 and is connected to the reflector 1. When it is necessary to pre-adjust the reflected light of the reflector 1, the adjustment movement of the adjustment portion 5 drives the reflector 1 to perform angular rotation adjustment relative to the rotation slot 3 in the corresponding direction, thereby causing the light reflected by the reflector 1 to be rotationally adjusted accordingly.

[0019] Specifically, Figure 2 As shown, the limit buckle 4 in this embodiment includes a connecting portion 4-1 provided on the reflector 1 and extending toward the rotating slot 3, and a rotating portion 4-2 provided on the connecting portion 4-1. In this embodiment, the connecting portion 4-1, the rotating portion 4-2 and the reflector 1 are provided in an integrated structure; correspondingly, as Figure 3As shown, the rotating slot 3 in this embodiment includes an arc-shaped receiving slot 3-1 provided on the outer side of the lamp mounting seat 2 for receiving the rotating portion 4-2, and a pair of elastic clamping portions 3-2 provided outside the lamp mounting seat 2 to limit the rotating portion 4-2 in the arc-shaped receiving slot 3-1. In this embodiment, a deformation channel 3-3 communicating with the arc-shaped receiving slot 3-1 is provided between the elastic clamping portions 3-2; wherein, as Figure 4 As shown, the elastic clamping portion 3-2 in this embodiment includes a pair of connecting plates 3-2-1 arranged on the vehicle lamp mounting seat 2 and respectively located at the upper and lower ends of the arc-shaped accommodating groove 3-1, and an elastic deformation plate 3-2-2 arranged at the outer end of the connecting plate 3-2-1 and extending obliquely toward the center of the arc-shaped accommodating groove 3-1, a deformation space is arranged between the outer end of the elastic deformation plate 3-2-2 and the connecting plate 3-2-1, and a spacing space forming a deformation channel 3-3 is arranged between the upper and lower elastic deformation plates 3-2-2; wherein, in this embodiment, the reflector 1 needs to be pre-adjusted in the up and down directions, so the rotating portion 4-2 in this embodiment is a horizontally arranged cylindrical structure, so that a circular rotating surface that can be horizontally rotated is arranged on the outer side of the rotating portion 4-2, so that the cylindrical rotating portion 4-2 can be horizontally rotatably arranged in the arc-shaped accommodating groove 3-1, The opening size of the deformation channel 3-3 when not deformed is smaller than the outer diameter of the cylindrical rotating part 4-2; during installation, the rotating part 4-2 squeezes the elastic clamping part 3-2, thereby causing the elastic deformation plate 3-2-2 on the elastic clamping part 3-2 to bend and deform toward the outer deformation space, and as the rotating part 4-2 gradually moves toward the arc-shaped accommodating groove 3-1, the deformation channel 3-3 between the upper and lower elastic deformation plates 3-2-2 also gradually expands. When the rotating part 4-2 enters the arc-shaped accommodating groove 3-1 through the deformation channel 3-3, the elastic clamping part 3-2 returns to its original position, thereby limiting the elastic deformation plate 3-2-2 on the outer side of the rotating part 4-2 to prevent the rotating part 4-2 from falling out; at this time, the connecting part 4-1 is located in the deformation channel 3-3 and a rotating space is provided between the elastic deformation plate 3-2-2 for facilitating the angle adjustment of the reflector 1.

[0020] Further, such as Figure 6 As shown, a rotation hole 19 is provided on the headlight mounting base 2 in this embodiment, wherein the adjusting portion 5 comprises an adjusting screw 6 which is inserted into the rotation hole 19 and passes through the headlight mounting base 2 front and back, and the adjusting screw 6 is rotatably connected to the headlight mounting base 2 through the rotation hole 19; wherein the outer side of the front end of the adjusting screw 6 is threadedly connected to a driving portion which is detachably mounted on the reflector 1; Further, such as Figure 1 and 2As shown, in order to facilitate the connection of the driving part and avoid affecting the molding of the reflector 1, in this embodiment, a mounting plate 7 for connecting the driving part and installed at a distance from the rear end of the reflector 1 is provided on the reflector 1. In this embodiment, the mounting plate 7 and the reflector 1 are relatively spaced apart, and an auxiliary connecting plate 20 extending toward the reflector 1 and connected to the reflector 1 is provided on the mounting plate 7. The auxiliary connecting plate 20 and the mounting plate 7 surround and form an installation adjustment space with an outer opening, and a mounting hole 8 for installing the driving part is opened on the mounting plate 7. The front end of the adjusting screw 6 is arranged in the mounting hole 8; further, a mounting hole 8 is arranged on the outer side of the rotating hole 19. A limiting boss 14 is provided on the outer side surface of the headlight mounting base 2 for limiting the nut end of the adjusting screw 6, and the adjusting screw 6 is clamped with an inner limiting portion which is limitedly arranged on the inner side surface of the headlight mounting base 2. The inner limiting portion includes a limiting contact portion 15 which is arranged in a circular ring shape, and a clamping inclined portion 16 which is connected to the inner side of the limiting contact portion 15 and gradually extends toward the adjusting screw 6 from the back to the front. A limiting groove 17 is provided on the adjusting screw 6 for clamping the inner end of the clamping inclined portion 16, so that the adjusting screw 6 can be rotated relative to the headlight mounting base 2 while ensuring that the position of the adjusting screw 6 relative to the headlight mounting base 2 in the front-to-back direction is fixed.

[0021] Specifically, Figure 5 As shown, the driving part in this embodiment includes an outer limiting part 9 which is threadedly connected to the outside of the adjusting screw 6 and limited on the outer surface of the mounting plate 7, a pair of deforming bayonet pins 10 which are arranged on the outer limiting part 9 and penetrate into the mounting hole 8, and an inner limiting protrusion 11 which is arranged on the outer surface of the deforming bayonet pins 10 and protrudes outward; an installation space 12 for the adjusting screw 6 to penetrate is provided between the deforming bayonet pins 10 in this embodiment; in this embodiment, a pair of deforming bayonet pins 10 are respectively arranged on the left and right sides of the outer limiting part 9, and an inclined deformation surface 13 which deforms inwardly and contacts the adjusting screw 6 is provided on the side of the deforming bayonet pin 10 facing the installation space 12; the deforming bayonet pins 10 in this embodiment are made of elastic material; as shown Figure 7 As shown, during installation, the adjusting screw 6 is rotated through the outer limiting portion 9 through the thread to enter the installation space 12. When entering the installation space 12, the adjusting screw 6 contacts the inclined deformation surface 13 and squeezes the deforming bayonet 10 outward. In the process of the adjusting screw 6 gradually penetrating, the deforming bayonet 10 is deformed outward under the action of the inclined deformation surface 13, so that the inner limiting protrusion 11 on the outer side of the deforming bayonet 10 moves outward and is limited on the inner side surface of the mounting plate 7; after the installation is completed, the outer side of the driving part is limited on the outer surface of the mounting plate 7 by the outer limiting portion 9, and the inner side of the driving part is limited on the mounting plate 7 by the inner limiting protrusion 11, so that the driving part is relatively fixedly installed on the mounting plate 7; as shown in FIG. Figure 8 and Fig. 9As shown, when the reflection angle of the reflector 1 needs to be pre-adjusted, the adjusting screw 6 is rotated so that the outer limit portion 9 drives the mounting plate 7 and the reflector 1 to move forward or backward or backward under the action of the thread. At this time, the driving portion moves in the corresponding direction along the adjusting screw 6, and during the movement, the limit buckle 4 on the reflector 1 rotates at a certain angle under the action of the rotating slot 3, so that the driving portion moves in the front and rear directions and slides in the up and down directions relative to the mounting hole 8. In addition, the inner limit protrusion 11 in this embodiment is provided with a side that contacts the surface of the mounting plate 7 and gradually moves from the center to both ends. A first arcuate contact surface 21 is bent outward, and a second arcuate contact surface 22 is gradually bent outward from the center to both ends on the side where the outer limit portion 9 contacts the surface of the mounting plate 7. The first arcuate contact surface 21 and the second arcuate contact surface 22 have the same curvature, so that when the reflector 1 is pre-adjusted for rotation, no matter whether the mounting plate 7 is in an upward or downward rotation position, the first arcuate contact surface 21 and the second arcuate contact surface 22 can both contact and limit the outer side surface of the mounting plate 7, so that the mounting plate 7 and the driving portion are firmly installed without a vibration gap during use.

[0022] Furthermore, if Figure 2 and 4 As shown, the inner side of the limit buckle 4 in this embodiment is provided with a transverse limit portion 18 connected to the reflector 1, and the transverse limit portion 18 is limitedly set at the inner ends of the rotating slot 3 and the elastic clamping portion 3-2. The rotating slot 3 and the elastic clamping portion 3-2 are both provided with a limiting plane 23 for installing the transverse limit portion 18. When the rotating portion 4-2 is inserted into the rotating slot 3, the transverse limit portion 18 contacts and limits the limiting plane 23, thereby making the installation positioning of the reflector 1 in the left and right directions more accurate.

[0023] Furthermore, if Fig.10 As shown, a pair of rotating slots 3 are provided and are horizontally arranged on the left and right sides of the lamp mounting base 2. The lamp mounting base 2 and the rotating slot 3 in this embodiment are integrally formed by injection molding. In this embodiment, in order to facilitate the injection molding of the rotating slot 3, a molding portion 24 is provided on the lamp mounting base 2 corresponding to the rotating slot 3 and protruding from the back to the front, so that the thickness of the position corresponding to the limit buckle 4 on the lamp mounting base 2 is the same as that of other positions, thereby ensuring the complete molding of the arc-shaped accommodating groove 3-1 and the elastic clamping portion 3-2, avoiding defects such as shrinkage holes, and ensuring the stable installation of the reflector 1.

[0024] This embodiment also discloses a method for installing a vehicle lamp installation structure capable of pre-adjusting a reflector, comprising the following steps: S1: Insert the adjusting screw 6 into the rotating hole 19 from the back to the front, so that the nut end of the adjusting screw 6 contacts the limiting boss 14 on the outer side of the lamp mounting seat 2, and then put the inner limiting part on the adjusting screw 6 at one end of the inner side of the lamp mounting seat 2; S2: Insert the driving part into the mounting hole 8 from the back to the front, so that the elastic clamping part 3-2 is arranged in an upper and lower position; S3: Move the reflector 1 from front to back, insert the rotating part 4-2 at the rear end of the reflector 1 into the deformation channel 3-3, and when moving backward, the rotating part 4-2 causes the elastic deformation plate 3-2-2 to bend and deform outward, thereby making the deformation channel 3-3 larger for the rotating part 4-2 to pass through, and after the rotating part 4-2 escapes from the deformation channel 3-3 and enters the arc-shaped receiving groove 3-1, the elastic clamping part 3-2 returns to its original position, thereby preventing the rotating part 4-2 from slipping outward; S4: Move the limiting contact part 15, so that the limiting contact part 15 on the inner limiting part contacts the inner side surface of the lamp mounting seat 2, and the inner end of the clamping inclined part 16 is clamped into the limiting clamping groove 17 of the adjusting screw 6 to achieve the positioning installation of the adjusting screw 6, so that the position of the adjusting screw 6 relative to the lamp mounting seat 2 is fixed and can be rotated relative to the lamp mounting seat 2; S5: While fixing the reflector 1, rotate the adjusting screw 6 so that the front end of the adjusting screw 6 enters the outer limit portion 9 through the threaded rotation, and continue to rotate the adjusting screw 6 so that the front end of the adjusting screw 6 enters the installation space 12 and contacts and squeezes the inclined deformation surface 13. Under the action of the inclined deformation surface 13, the deformation pin 10 is deformed outward and contacts the mounting plate 7, and then the inner limit protrusion 11 on the deformation pin 10 is limited on the inner side surface of the mounting plate 7 after the outward deformation.

[0025] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.

10. A method for installing a vehicle lamp installation structure capable of pre-adjusting a reflector, comprising the following steps: S1: Insert the adjusting screw (6) into the rotating hole (19) from the back to the front, so that the nut end of the adjusting screw (6) contacts the limiting boss (14) on the outer side of the lamp mounting seat (2) to limit the position, and then put the inner limiting part on the adjusting screw (6) at one end of the inner side of the lamp mounting seat (2); S2: inserting the driving part into the mounting hole (8) from the back to the front, so that the elastic clamping part (3-2) is arranged in an upper and lower position; S3: Move the reflector (1) from front to back, and the rotating part (4-2) at the rear end of the reflector (1) When the rotating part (4-2) is inserted into the deformation channel (3-3) and moves backward, the elastic deformation plate (3-2-2) is bent and deformed outward, thereby making the deformation channel (3-3) larger to facilitate the passage of the rotating part (4-2); after the rotating part (4-2) is separated from the deformation channel (3-3) and enters the arc-shaped accommodating groove (3-1), the elastic clamping part (3-2) returns to its original position, thereby preventing the rotating part (4-2) from escaping outward; S4: moving the limiting contact portion (15) so that the limiting contact portion (15) on the inner limiting portion contacts the inner side surface of the vehicle lamp mounting seat (2) and the inner end of the clamping inclined portion (16) is clamped into the limiting clamping groove (17) of the adjusting screw (6) to achieve the positioning installation of the adjusting screw (6), so that the position of the adjusting screw (6) relative to the vehicle lamp mounting seat (2) is fixed and the adjusting screw (6) can be rotated relative to the vehicle lamp mounting seat (2); S5: While fixing the reflector (1), the adjusting screw (6) is rotated so that the front end of the adjusting screw (6) enters the outer limiting portion (9) through the threaded rotation, and the adjusting screw (6) is further rotated so that the front end of the adjusting screw (6) enters the installation space (12) and contacts and squeezes the inclined deformation surface (13). Under the action of the inclined deformation surface (13), the deformation pin (10) is deformed outwardly and contacts the installation plate (7), and then the inner limiting protrusion (11) on the deformation pin (10) is limited on the inner side surface of the installation plate (7) after the outward deformation.
