DETAILED DESCRIPTION

[0034] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the various embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] The embodiment of the utility model provides a motorcycle taillight, such as Figures 1 to 8 As shown, it comprises a tail light cover 2 having a cavity 1 and a lighting module installed in the cavity 1, wherein the tail light cover 2 has a mounting side mounted on the motorcycle body and a lighting side made of a light-transmitting material, and the mounting side is provided with an aviation plug 3 for connecting the lighting module to an external lighting system;

[0036] The lighting module includes a main lighting unit, an auxiliary lighting unit and a control unit. A transfer platform 4 fixed to the inner wall of the taillight cover 2 is provided on one side of the control unit. The control unit is electrically connected to the main lighting unit and the auxiliary lighting unit through the transfer platform 4.

[0037] The adapter 4 is provided with at least one terminal block 5 for plugging in a plurality of pre-configured terminal wires. The main lighting unit and the auxiliary lighting unit are electrically connected to the control unit through the terminal wires and the terminal block 5 .

[0038] Specifically, in this embodiment, when the main lighting unit is not bright enough or cannot work properly, the auxiliary lighting unit can play a role of reinforcement and redundancy, making the motorcycle taillight more reliable and durable, and improving safety during driving.

[0039] The terminal wires connect each unit in the lighting module to the terminal block 5. Electrical connection can be achieved by plugging each terminal wire into the corresponding interface of the terminal block 5, so that the terminal wires can be distributed in the cavity 1 in an orderly and stable manner, making it convenient for maintenance personnel to disassemble and assemble.

[0040] The taillight cover 2 includes a front cover 21 and a rear cover 22 buckled with the front cover 21 . The rear cover 22 is a lighting side and is made of a light-transmitting material. The front cover 21 is a mounting side and is used to be fixed on the motorcycle body.

[0041] In a preferred embodiment of the present utility model, the taillight cover 2 is bent through a plate to separate the cavity 1 into an installation chamber 6, a first installation groove 7 and a second installation groove 8, and the installation chamber 6, the first installation groove 7 and the second installation groove 8 are interconnected;

[0042] The control unit is loaded on the first circuit board 9, the main lighting unit is loaded on the second circuit board 10, and the auxiliary lighting unit is loaded on the third circuit board 11. The first circuit board 9 is installed at the bottom of the installation chamber 6, the third circuit board 11 is installed in the first installation groove 7, and the second circuit board 10 is installed in the second installation groove 8. The first circuit board 9, the second circuit board 10 and the third circuit board 11 are all fixed to the taillight cover 2 by bolts.

[0043] Specifically, in this embodiment, the first circuit board 9 , the second circuit board 10 and the third circuit board 11 are installed layer by layer, and gaps are left between each other for terminal wires to pass through, so that the distribution of circuit components in the cavity 1 is more orderly.

[0044] Due to the different road conditions when the actual motorcycle is driving, when the road conditions are poor, there are situations where the vehicle is bumpy and vibrates greatly. At this time, the layered and firmly installed first circuit board 9, second circuit board 10 and third circuit board 11 are not easy to shift, reducing the probability of components on the circuit boards being scratched and damaged.

[0045] In a preferred embodiment of the utility model, two bosses 12 disposed opposite to each other are formed by die-casting at both ends of the taillight cover 2 along the length direction, and the bottom wall of the cavity 1 and the end surfaces of the two bosses 12 close to each other are surrounded to form an installation chamber 6;

[0046] A first limiting rib 13 is disposed on one side of the boss 12 away from the installation side, and the inner wall of the cavity 1, the end surfaces of the two bosses 12 away from the installation side and the two first limiting ribs 13 disposed opposite to each other are surrounded to form a first installation groove 7;

[0047] A second limiting rib 14 is disposed above the boss 12 away from the installation side, and the inner wall of the cavity 1 , the end surfaces of the two bosses 12 away from the installation side and the two second limiting ribs 14 disposed opposite to each other form a second installation groove 8 .

[0048] Specifically, in this embodiment, the first limiting ridge 13 is located on one side of the boss 12 away from the center of the cavity 1 . Two first limiting ridges 13 are arranged opposite to each other, sandwiching the third circuit board 11 therebetween to prevent the third circuit board 11 from moving laterally.

[0049] The second limiting ridge 14 is located at the upper edge of the boss 12 and is higher than the first limiting ridge 13, so that when the second circuit board 10 is clamped between the two second limiting ridges 14, the second circuit board 10 is located on the side of the third circuit board 11 away from the first circuit board 9, thereby preventing the second circuit board 10 from moving laterally.

[0050] In a preferred embodiment of the utility model, the two ends of the taillight cover 2 along the height direction are recessed inward to form a limiting protrusion 15 for clamping the first circuit board 9 and the third circuit board 11. The first circuit board 9 is provided with a first limiting groove 16 for clamping to the limiting protrusion 15, and the third circuit board 11 is provided with a second limiting groove 17 for clamping to the limiting protrusion 15.

[0051] Specifically, in this embodiment, the limiting protrusion 15 includes an upper protrusion 151 and a lower protrusion 152, and the first limiting groove 16 includes a first upper limiting groove 161 and a first lower limiting groove 162, so that the first circuit board 9 can slide along the limiting protrusion 15 to the bottom of the installation chamber 6, and the two ends of the first circuit board 9 are fixed to the front cover 21 by bolts;

[0052] The second limiting groove 17 includes a second upper limiting groove 171 and a second lower limiting groove 172 , so that the third circuit board 11 can slide along the limiting protrusion 15 into the first installation groove 7 , and the third circuit board 9 is fixed to the tail light cover 2 by bolts.

[0053] A third limiting groove 29 is provided on the lower side of the second circuit board 10, and the third limiting groove 29 is tilted so that the second circuit board 10 is tilted when it slides into the second mounting groove 8 along the limiting protrusion 15, and the lower part of the second circuit board 10 is tilted toward the mounting side, and the upper part of the second circuit board 10 is tilted toward the lighting side.

[0054] After the second circuit board 10 slides into the second mounting groove 8 along the limiting protrusion 15, it is in a vertical state, so that the contact area between the third circuit board 11 and the second circuit board 10 is reduced, further reducing the probability of components on the two circuit boards rubbing against each other and causing damage to the components.

[0055] In a preferred embodiment of the present invention, the second circuit board 10 is provided with a recess 18 for making way for the third circuit board 11 .

[0056] Specifically, in this embodiment, the clearance groove 18 is opened above the second circuit board 10 , and after the third circuit board 11 is installed, the rear side of the waist of the third circuit board 11 is clamped in the clearance groove 18 .

[0057] In a preferred embodiment of the utility model, a bolt seat 19 for bolting the third circuit board 11 is protruded on the bottom wall of the installation chamber 6, and the adapter 4 is fixed on the side wall of the bolt seat 19. The adapter 4 includes a vertical connection part 41 and an inclined connection part 42. The terminal block 5 includes a first terminal block 51 and a second terminal block 52. The vertical connection part 41 is provided with a waist-shaped hole 20 for installing the first terminal block 51, and the inclined connection part 42 is provided with side grooves 23 for installing two second terminal blocks 52 at both ends along the length direction. The third circuit board 11 is connected to the first terminal block 51 through a terminal wire, the second circuit board 10 is connected to the second terminal block 52 through a terminal wire, and the first circuit board 9 is connected to the first terminal block 51 and the second terminal block 52 through terminal wires.

[0058] Specifically, in this embodiment, the transfer platform 4 is a plastic component, and is fixed to the side wall of the bolt seat 19 by bolts.

[0059] During the actual installation process, the lead-out terminal wires of the second circuit board 10 are plugged into the side of the first terminal block 51 facing the rear cover 22, and the corresponding lead-out terminal wires of the first circuit board 9 are plugged into the side of the first terminal block 51 facing the front cover 21, so that the first circuit board 9 and the second circuit board 10 are electrically connected;

[0060] The terminal wires led out of the third circuit board 11 are plugged into the second terminal block 52 , and the corresponding terminal wires led out of the first circuit board 9 are plugged into the second terminal block 52 , so that the third circuit board 11 and the first circuit board 9 are electrically connected.

[0061] The terminal wires are orderly distributed in the cavity 1, which reduces the probability of the terminal wires being entangled with each other or being squeezed and rubbed by the plate.

[0062] The first circuit board 9 should be inserted into the cavity 1 before the transfer platform 4 to avoid the transfer platform 4 blocking the installation of the first circuit board 9 .

[0063] In a preferred embodiment of the present invention, a cover sheet 24 is detachably mounted on the opening of the waist-shaped hole 20 facing the third circuit board 11 , and the cover sheet 24 is provided with a through hole 25 for the terminal wire to pass through.

[0064] Specifically, in this embodiment, each terminal wire is inserted into the first terminal block 51 through the through hole 25, so as to avoid the situation where the terminal wires are cross-distributed, resulting in low wire management efficiency during maintenance and disassembly by maintenance personnel.

[0065] In a preferred embodiment of the present invention, the four corners of the cover plate 24 are provided with limiting holes 26, and the side of the vertical connection portion 41 facing the third circuit board 11 is provided with four ball-head limiting posts 27 that are engaged with the limiting holes 26, and the cover plate 24 is made of rubber material.

[0066] Specifically, in this embodiment, the inner diameter of the limiting hole 26 is smaller than the ball head of the ball head limiting column 27. When installing the cover plate 24, the through hole 25 is aligned with the ball head limiting column 27 so that the through hole 25 passes through the ball head limiting column 27. The through hole 25 is deformed to allow the ball head to pass through. After the through hole 25 passes through the ball head, the through hole 25 returns to its original shape so that the cover plate 24 is clamped on the ball head limiting column 27 and is not easy to fall out.

[0067] When removing the cover plate 24 , the maintenance personnel peel off the cover plate 24 from the waist-shaped hole 20 to separate the through hole 25 from the ball head limiting column 27 . The operation is simple and convenient.

[0068] In a preferred embodiment of the present invention, a reinforcing convex ring 28 is provided at the opening of the through hole 25 .

[0069] Specifically, in this embodiment, by providing the reinforcing protruding ring 28 , the probability of the cover plate 24 being worn and broken due to the friction between the terminal wire and the inner wall of the through hole 25 is reduced.

[0070] In summary, the lighting intensity of the motorcycle taillight is improved by setting a main lighting unit and an auxiliary lighting unit. After the terminal block 5 is set, the terminal wires for electrically connecting the main lighting unit and the control unit are connected to the terminal block 5, and the terminal wires for electrically connecting the auxiliary lighting unit and the control unit are connected to the terminal block 5. During installation, the terminal wires can be orderly distributed in the cavity 1 of the taillight cover 2, which plays a role in organizing the wires, thereby preventing the terminal wires in the cavity 1 from being entangled with each other or squeezed by the lamp cover, causing the terminal wires to be worn and broken. It can also avoid the situation where maintenance personnel need to organize the wires before removing the circuit board due to the entanglement of the terminal wires, thereby improving the efficiency of circuit board removal and maintenance.

[0071] When disassembled, the main lighting unit, auxiliary lighting unit and control unit are installed in layers in the taillight cover 2, and the circuit boards carrying each circuit unit are installed reliably. Even if the motorcycle is bumped or vibrated during driving, the circuit boards are not easily scratched or squeezed against each other, reducing the probability of damage to the terminal wires.
