[0034] The specific implementation modes of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation modes described herein are only used to illustrate and explain the present invention, and the protection scope of the present invention is not limited to the specific implementation modes described below.

[0035] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "set", "provided with", and "connected" should be understood in a broad sense. For example, the connection can be a direct connection or an indirect connection through an intermediate medium, a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate connection member, and it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0036] In addition, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, features defined as "first" and "second" may explicitly or implicitly include one or more of the said features.

[0037] See also Figures 2 to 4 The utility model provides a lamp connection system, including multiple driving circuit boards 4, at least one connecting circuit board 5 and multiple light-emitting units, wherein the connecting circuit board 5 is electrically connected between the multiple driving circuit boards 4, and a plurality of non-intersecting connecting circuit board printed lines 51 are provided on the connecting circuit board 5. Of course, it can be understood that the connecting circuit board printed lines 51 on the connecting circuit board 5 can be preferably arranged to be parallel to each other. Multiple light-emitting units are respectively arranged on different driving circuit boards 4. The light-emitting units include light-emitting elements 1 and driving modules 2. For example, each light-emitting unit includes at least one LED load (i.e., light-emitting element 1) and a driving module 2. The light-emitting element 1 and the driving module 2 are electrically connected via the driving circuit board 4, and the multiple light-emitting units are electrically connected via the driving circuit board 4 and the connecting circuit board printed lines.

[0038] The utility model provides a lamp connection system, which realizes the connection of power and signals between light-emitting units by routing on a circuit board. Compared with the traditional wiring harness connection method, since the signal routing on the connecting circuit board 5 is parallel, the magnetic field generated around the printed wire 51 of the connecting wire board is smaller, thereby reducing mutual interference between signals, thereby enabling the electromagnetic compatibility performance of the entire lamp system to be better.

[0039] Combination Figure 2 The light-emitting unit may specifically include a position light unit for indicating the width of the vehicle, a turn light unit for indicating the turning direction, and a brake light unit for indicating that braking is in progress. The position light unit, the turn light unit, and the brake light unit are connected in parallel to form a complete lamp unit, and the lamp unit and the control module 3 are connected in series, so that the position light unit, the turn light unit, and the brake light unit can be independently controlled by the control module 3.

[0040] Specifically, the position light unit may include a left first position light unit, a left second position light unit, a right first position light unit and a right second position light unit connected in series by a connecting circuit board 5; the turn signal unit includes a left first turn signal unit, a left second turn signal unit, a right first turn signal unit and a right second turn signal unit connected in series by a connecting circuit board 5; the brake light unit includes a left first brake light unit, a left second brake light unit, a right first brake light unit and a right second brake light unit connected in series by a connecting circuit board 5. It should be noted that the position light unit, the turn signal unit and the brake light unit The electrical connection between these three units can also be directly connected through the connecting harness 6 to facilitate the arrangement and installation of the light-emitting units. Of course, it can be understood that the electrical connection between the light-emitting units can be flexibly achieved by using the connecting harness 6 or the connecting circuit board 5. If there is a relatively regular and ample space between the two light-emitting units that need to be electrically connected for the connection circuit board 5 to be arranged, the connecting circuit board 5 should be used as much as possible to achieve the electrical connection. If there is no relatively regular and ample space between the two light-emitting units for the connection circuit board 5 to be arranged, the connecting harness 6 should be used as a priority to achieve the electrical connection between the two light-emitting units.

[0041] Further, see Figure 2 and Figure 4 , the connection circuit board 5 also includes a connection line board substrate 52 and at least two connection line board connection seats 53. For example, a connection line board connection seat 53 may be provided at each end of the connection line board substrate 52 for connection with the driving circuit board 4, and the two connection line board connection seats 53 are electrically connected via the connection line board printed wire 51. Specifically, the connection line board printed wire 51 includes a CANH signal line (CANH line), a CANL signal line (CANL line), a power line (supply line) and a ground line (GND line). The connection line board printed wire 51 may be provided on the same board surface of the connection line board substrate 52, and a wire anti-interference gap is formed between adjacent connection line board printed wires 51 to prevent the magnetic field generated by each wire when powered on from affecting the adjacent wires.

[0042] In addition, if Figure 4 As shown, a connecting wire board through hole 521 for a connecting member (such as a bolt) to pass through may be provided on the connecting wire board substrate 52, and the bolt can be connected to the vehicle body so that the connecting wire board substrate 52 is abutted between the bolt and the vehicle body to achieve the installation and fixation of the connecting circuit board 5, so that during the driving of the vehicle, the connecting circuit board 5 is not easy to shake and is not easy to be damaged by collision.

[0043] Furthermore, if Figure 3As shown, the driving circuit board 4 specifically includes a driving board wire 41, a driving board substrate 42, at least two driving board connection seats 43 and at least two driving board sockets 44. For example, a driving board socket 44 can be provided at each end of the driving board substrate 42, and the circuit board 5 is connected to the driving circuit board 4 to realize electrical connection through the connection of the connecting wire board connection seat 53 and the driving board socket 44. In addition, a harness socket (not shown in the figure) for connecting to the connecting wire harness 6 can also be provided on the driving board substrate 42, so that it can be used to connect to the connecting wire harness 6, so as to realize the connection between the light-emitting units via the connecting wire harness 6. The light-emitting element 1 and the driving module 2 can be connected to the driving board connection seat 43, and the driving board connection seat 43 and the driving board connection seat 43, the driving board connection seat 43 and the corresponding driving board socket 44, and the harness socket and the driving board connection seat 43 are all electrically connected via the driving board wire 41, so that the series connection between the light-emitting element 1 and the driving module 2 can be realized and the light-emitting element 1 and the driving module 2 can be connected to the power supply module.

[0044] Specifically, the drive board wires 41 also include a CANH signal line, a CANL signal line, a power line and a ground line. These drive board wires 41 are arranged on the same board surface of the drive board substrate 42, and a wire anti-interference gap is formed between adjacent drive board wires 41 to prevent the magnetic field generated by each wire when powered on from affecting the adjacent wires.

[0045] In addition, if Figure 3 As shown, the drive board substrate 42 is provided with a drive board through hole 421 for a connecting piece (such as a bolt) to pass through, and the bolt can be connected to the vehicle body so that the drive board substrate 42 is abutted between the bolt and the vehicle body to achieve the installation and fixation of the drive circuit board 4, so that during the driving of the vehicle, the drive circuit board 4 is not easy to shake and is not easy to be damaged by collision.

[0046] Based on the above-mentioned configuration of the driving circuit board 4 and the connecting circuit board 5, see Figure 2 The connection harness 6 may specifically include a CANH signal harness (ie Figure 2 CANH wiring harness), CANL signal wiring harness (ie Figure 2 CANL harness in), power harness (i.e. Figure 2 supply harness) and ground harness (i.e. Figure 2GND harness in), it should be noted that the control module 3 and the driver circuit board 4 are not convenient to connect the circuit board 5 due to the long distance, so the connection harness 6 is generally used for connection, and the control module 3 and the driver circuit board 4 only need to be connected by CANH signal harness, CANL signal harness and ground harness. Among the three units of the position light unit, the turn light unit and the brake light unit, only one of the drive circuit board 4 and the power supply module needs to be connected through the power harness, so that the power supply module can supply power to the entire lamp connection system, so as to realize the power-on operation of the light-emitting element 1 and the drive module 2 on the drive circuit board 4, and this power supply method is compared with the traditional layout method of connecting to each drive module 2 and the light-emitting element 1 respectively, and reduces the cross-connection of the harness in the three units of the position light unit, the turn light unit and the brake light unit, thereby improving the electromagnetic compatibility performance of the whole lamp, and because the wiring of the circuit board is solidified and regular, it is easy to realize the connection of the ground wires together, which increases the reflux capacity of the ground wire signal, invisibly reduces the electromagnetic radiation, improves the anti-interference ability, and reduces the mutual interference of electromagnetic radiation in the circuit from the source.

[0047] In addition, the specific control signal is transmitted through the CANH signal line and the CANL signal line, so that the control signal of the control module 3 can be sent to the driving module 2 to adjust the light emitting element 1 via the driving module 2 to implement the execution of the control signal.

[0048] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.
