[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This embodiment discloses a plug-in connected automotive taillight, which aims to solve the problems of complex maintenance and signal transmission being easily affected by poor contact in existing automotive taillights.

[0022] The plug-in connected automotive taillight of this embodiment includes a protective shell 1, a connecting component, a mounting base 9, a pad 10, and a wiring terminal 12. The protective shell 1 is made of ABS engineering plastic through one-piece injection molding, and has waterproof and impact-resistant properties, making it suitable for the installation space of taillights in most compact cars.

[0023] One end of the protective shell 1 is fixedly connected to the extension frame 2 via injection molding. The extension frame 2 has a pre-drilled mounting cavity to match the lamp core 3. The lamp core 3 uses an integrated LED module, which is embedded into the center of the extension frame 2 with an interference fit to ensure a stable installation. The end of the extension frame 2 away from the protective shell 1 is attached to the connecting plate 4. The connecting plate 4 is made of stainless steel and has several through holes 5 for fixing it to the car body sheet metal with bolts. The extension frame 2 has symmetrically injection-molded elastic buckles 7 on both sides. The buckles 7 are made of TPU elastic material and have triangular teeth integrally formed on the sides. Constraint covers 8 are welded to corresponding positions on both sides of the connecting plate 4. The constraint covers 8 have mounting grooves inside that match the buckles 7. During assembly, the buckles 7 are aligned with the mounting grooves and inserted, and the teeth engage with the grooves on the inner wall of the mounting grooves, achieving quick insertion and fixation of the connecting plate 4 and the extension frame 2. The top and bottom of the protective shell 1 are integrally formed with extension ears 6. The extension ears 6 have an L-shaped structure, and their free ends extend to the outside of the extension frame 2. They are used to cooperate with the positioning holes of the vehicle body during assembly and to assist the connection plate 4 in precise alignment.

[0024] The protective shell 1 has a mounting base 9 fixed to its bottom by bolts. The mounting base 9 is made of rigid PVC material, and its top has two symmetrically arranged elastic buckles that are integrally formed. The elastic buckles are barbed and have the ability to deform and recover. The pad 10 is made of rubber and has a limiting groove 11 on its surface that matches the elastic buckles. During assembly, the elastic buckles of the mounting base 9 are aligned with the limiting groove 11 and pressed. After the elastic buckles deform, they are inserted into the limiting groove 11, realizing the snap-fit ​​fixation between the mounting base 9 and the pad 10. The pad 10 can buffer the vibration during vehicle operation and prevent the parts from loosening.

[0025] A wiring hole is reserved at the end of the protective shell 1 away from the extension frame 2. The wiring terminal 12 is made of copper alloy and is fixedly connected to the wire of the lamp core 3 through a crimping process. The wiring terminal 12 is covered with an insulating protective sleeve to ensure long-term reliability. After the wiring terminal 12 is plugged into the main wiring harness of the car, the power supply and signal transmission of the lamp core 3 are realized.

[0026] The specific working principle is as follows: the main wiring harness of the car establishes a conductive connection with the lamp core 3 through the terminal 12. Since the terminal 12 and the lamp core 3 are fixed by crimping and the plug-in structure ensures that the contact surfaces are tightly fitted, it can reduce the problem of poor contact caused by oxidation and loosening, and make the braking, steering, reversing and other signals transmit stably.

[0027] When the lamp core 3 burns out or the taillight is damaged by a collision, there is no need to disassemble the entire vehicle sheet metal. Simply: loosen the fixing bolts in the through hole 5 of the connecting plate 4; press the buckles 7 on both sides of the extension frame 2 to disengage the clips from the slots of the constraint cover 8, and the connecting plate 4 can be separated from the extension frame 2; directly plug and unplug the lamp core 3 or the protective shell 1 for replacement.

[0028] During assembly, the extension ear 6 is aligned with the positioning hole on the vehicle body to ensure that the through hole 5 of the connecting plate 4 is precisely aligned with the mounting hole on the vehicle body. After the bolts are tightened, the elastic deformation of the pad 10 can compensate for the minor error of the mounting surface, while absorbing driving vibration, preventing parts from loosening, and ensuring the overall installation stability of the taillight.

[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
