The limiting mechanism 6 includes a limiting insert 61 and a limiting slot 62. The limiting insert 61 is used to cooperate with the limiting slot 62, so that the inspection gap between the end surface 5 and the mating surface 4 is uniform. The limiting mechanism 6 prevents the bumper 2 and the rear tail lamp 1 from having no limit, resulting in an uneven inspection gap between the end surface 5 and the mating surface 4 when the two are installed on the body sheet metal 3, further improving the appearance quality and avoiding the return of the lamp caused by the uneven inspection gap. Specifically, in order to ensure the uniformity of the inspection gap, the number of limiting mechanisms 6 can be set according to the length and area of ​​the mating surface 4 or the end surface 5. In this embodiment, the rear taillight 1 has three end surfaces 5, and the bumper 2 has three corresponding mating surfaces 4. One end surface 5 corresponds to one mating surface 4. Four limiting mechanisms 6 are arranged between the rear taillight 1 and the bumper 2. Only one limiting mechanism 6 is arranged at each of the two short end surfaces 5, and two limiting mechanisms are arranged at the long end surface 5.

[0026] In order to improve the aesthetic appearance and recognition of the rear taillight 1, the rear taillight 1 includes a lamp housing 11, a lamp cover 12, a decorative frame 13, and an LED light source board 14. The lamp cover 12 is welded to the lamp housing 11 to form a sealed cavity 7. The LED light source board 14 is disposed on the decorative frame 13 and is disposed on the lamp housing 11 within the cavity 7 through the decorative frame 13. A first light source sink 131 in the shape of a Chinese character "Ri" is provided on the decorative frame 13. A plurality of first light outlet openings 132 are provided at the bottom of the first light source sink 131. A corresponding number of first light sources 141 are provided on the LED light source board 14, and one first light source 141 corresponds to one first light outlet opening 132. A first small cover 133 is provided at the top of the first light source sink 131, and the first small cover 133 is used to cover the inside of the first light source sink 131. Two platforms 134 arranged vertically are further provided on the inner side of the first light source sink 131 of the decorative frame 13. A second light source sink 135 is provided on the upper platform 134, and a third light source sink 136 is provided on the lower platform 134. A plurality of reflecting bowls 137 are respectively provided in the second light source sink 135 and the third light source sink 136. A second light outlet opening 138 is provided at the bottom of the reflecting bowl 137. A second light source 142 corresponding to the number of second light outlet openings 138 on the second light source sink 135 and a third light source 143 corresponding to the number of second light outlet openings 138 on the third light source sink 136 are provided on the LED light source board 14. In this embodiment, the light emitted by the first light source 141 enters the first light source sink 131 through the first light outlet opening 132 and then exits through the lamp cover 12 to form a position / brake light function beam. In order to improve the quality of the position / brake light function beam, a first small cover 133 is provided on the first light source sink 131. A light distribution pattern is provided on the inner surface of the first small cover 133. Through the setting of the first small cover 133, not only can the position / brake light function beam be optimized, but also a shielding effect can be achieved to prevent the internal structure of the first light source sink 131 from being seen, further improving the appearance effect. The light emitted by the second light source 142 enters the second light source sink 135 through the second light outlet opening 138, is reflected by the reflecting bowl 137, and then exits through the lamp cover 12 to form a rear turn signal function beam; the light emitted by the third light source 143 enters the third light source sink 136 through the second light outlet opening 138, is reflected by the reflecting bowl 137, and then exits through the lamp cover 12 to form a reverse light function beam. The second light source sink 135 and the third light source sink 136 are used to concentrate the light, improve the utilization efficiency of the light, and further improve the optical quality of the function beam.

[0027] In order to prevent light from collided between functional light beams, a circle of bosses 8 are respectively provided at the top notch of the second light source sink 135 and the third light source sink 136. The bosses 8 are used to block light and prevent light from collided, thereby preventing the light emitted by the first light source sink 131 from collided to the front of the second light source sink 135 or the third light source sink 136, affecting the functional light beam of the turn signal lamp and the functional light beam of the reverse light, further improving the recognition of the functional light beam, and thus improving driving safety. Specifically, a working distance of at least 0.5 mm is provided between the top of the boss 8 and the lampshade 12, and the setting of the working distance prevents the boss 8 from contacting the lampshade 12, and friction between the two during driving causes damage to the appearance.

[0028] In order to prevent the corners of the rear tail lamp 1 from fogging after use, a plurality of airflow holes 139 are provided on the decorative frame 13, and the airflow holes 139 are used for the circulation of hot air flow in the cavity 7. Specifically, the decorative frame 13 is provided with at least one airflow hole 139 on the four sides facing the lamp housing 11; when the rear tail lamp 1 is working, the hot air flow generated by the LED light source board 14 can be dispersed through the airflow holes 139 on the four sides of the decorative frame 13, and flow around inside the cavity 7, thereby preventing the hot air flow from gathering in the decorative frame 13 and unable to flow to the corners of the lampshade 12, so that the corners of the lampshade 12 are fogged due to the temperature difference.

[0029] Furthermore, the lampshade 12 is provided with a second small cover 121 corresponding to the second light source groove 135, and a third small cover 122 corresponding to the third light source groove 136; the inner surfaces of the second small cover 121 and the third small cover 122 are respectively provided with light distribution patterns, through which the rear turn signal light beam and the reversing light light beam can be optically optimized, and at the same time, it can also play a shielding role to prevent the internal structure of the second light source groove 135 and the third light source groove 136 from being seen, thereby further improving the appearance effect.

[0030] Furthermore, the limiting insert 61 is arranged on the rear taillight 1, and the limiting slot 62 is arranged on the bumper 2. Of course, those skilled in the art will appreciate that the limiting insert 61 may also be arranged on the bumper 2, and the limiting slot 62 may be arranged on the rear taillight 1. Specifically, the end face 5 is arranged on the lampshade 12, and the lamp housing 11 is provided with an extension platform 111 on the side opposite to the mating surface 4, the limiting insert 61 is vertically arranged on the bottom surface of the extension platform 111, and both ends of the limiting insert 61 are respectively provided with abutment platforms 611, and the abutment platforms 611 are used to abut against two opposite notch edges 621 of the limiting slot 62 in the length direction, and the inspection gap between the end face 5 and the mating surface 4 is adjusted by the cooperation between the limiting insert 61 and the limiting slot 62, so as to ensure that the inspection gap between the two is uniform. In this embodiment, the edge of the lampshade 12 is provided with a first flange 123 extending inward, and the end face 5 is provided on the side of the first flange 123 facing outward; the edge of the bumper 2 is provided with a second flange 21 extending inward, and the edge of the second flange 21 is provided with a third flange 22 extending toward the rear taillight 1, the second flange 21 has a mating surface 4 facing the end face 5, and the third flange 22 has a limiting slot 62. When the rear taillight 1 is installed on the body sheet metal 3, the limiting insert 61 on the lamp housing 11 is inserted into the limiting slot 62, so that the rear taillight 1 is connected to the bumper 2, and the abutment platform 611 abuts against the two opposite notch edges 621 of the limiting slot 62, so that the end face 5 is limited on one side of the mating surface 4, thereby ensuring that the inspection gap between the end face 5 and the mating surface 4 is uniform.

[0031] Furthermore, the mating surface 4 is inclined at an angle, the inclination angle a is 3-10 degrees, the end surface 5 is parallel to the mating surface 4, and the distance d between the end surface 5 and the mating surface 4 is the required uniform inspection gap. By tilting the end surface 5 and the mating surface 4, the extension platform 111 is hidden in the positive projection of the lampshade 12, preventing the extension platform 111 from being seen from the inspection gap, and further improving the appearance efficiency.

[0032] In order to prevent the third flange 22 from being deformed by force, a fourth flange 23 is provided at the edge of the third flange 22. The fourth flange 23 is used to strengthen the strength of the third flange 22 and further improve the uniformity of the inspection gap between the end face 5 and the mating surface 4.
