[0031] The core of the present application is to provide a connection structure for connecting a lamp board and a driving board, so as to reduce the space occupied inside the vehicle lamp while realizing the connection between the lamp board and the driving board.

[0032] Another core of the present application is to provide a vehicle lamp having the above connection structure.

[0033] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0034] For the connection between the lamp board and the driving board of traditional automotive headlights, generally a connector is used and connected through a wire harness. However, it is necessary to first weld the connector on the lamp board and the driving board, and then connect the wire harness to the connector through a wire harness plug, resulting in increased costs and occupying a large amount of space inside the headlight, making the volume of the headlight larger.

[0035] Therefore, as Figure 1 shown, an embodiment of the present application discloses a connection structure for connecting a lamp board and a driving board, including a connecting member 100. By directly connecting the two plugging ends 101 of the conductive connecting member 100 to the lamp board 200 and the driving board 300, the number of parts can be reduced, the connection structure can be simplified, not only the reliable connection between the lamp board 200 and the driving board 300 is achieved, but also the space occupied inside the headlight is reduced, the cost is lowered, and the volume of the headlight can be reduced.

[0036] Next, the connection structure for connecting a lamp board and a driving board disclosed in the embodiments of the present application will be specifically explained and described in conjunction with Figures 1 to 5 this.

[0037] Among them, as Figure 1 and Figure 2 shown, the connecting member 100 is made of a conductive body, and the connecting member 100 has two oppositely arranged plugging ends 101, so that the two plugging ends 101 of the connecting member 100 can respectively cooperate with the jacks on the lamp board 200 and the driving board 300, thereby realizing the electrical connection between the lamp board 200 and the driving board 300, reducing the number of parts, simplifying the connection structure, not only achieving the reliable connection between the lamp board 200 and the driving board 300, but also reducing the space occupied inside the headlight, lowering the cost, and reducing the volume of the headlight. The connecting member 100 can be a pin made of tungsten carbide material, or a metal part made of metal materials such as aluminum and copper, which is not limited herein.

[0038] In some embodiments, thread portions may be provided at the two insertion ends 101 of the connecting member 100. After the two insertion ends 101 of the connecting member 100 are respectively inserted into the jacks on the lamp board 200 and the driving board 300, fastening members such as nuts can be used for locking and fixing, so as to facilitate the disassembly, assembly and maintenance of the lamp board 200 and the driving board 300. When the lamp board 200 or the driving board 300 is damaged, only the damaged part needs to be replaced, and there is no need to replace the whole, which reduces the cost and improves the convenience of maintenance.

[0039] In some embodiments, as Figure 3 shown, a welding area 1011 may be provided at the end of the insertion end 101, so that the two insertion ends 101 are respectively connected to the lamp board 200 and the driving board 300 by welding, so as to improve the connection strength between the connecting member 100 and the lamp board 200 and the driving board 300 respectively, and avoid the situations of virtual connection and disconnection. After the two insertion ends 101 of the connecting member 100 are respectively inserted into the jacks on the lamp board 200 and the driving board 300, welding fixation can be carried out in the welding area 1011 at the end of the insertion end 101 by means of soldering. In order to ensure the firmness of the connection between the two insertion ends 101 of the connecting member 100 and the lamp board 200 and the driving board 300, a gap of 0.1 mm needs to be reserved between the insertion end 101 and the jack, so that the solder can flow into the gap between the insertion end 101 and the jack, thereby increasing the contact area of the welding between the insertion end 101 of the connecting member 100 and the lamp board 200 and the driving board 300, and improving the connection strength between the connecting member 100 and the lamp board 200 and the driving board 300 respectively. It should be noted that the welding area 1011 is the area provided at the end of the insertion end 101 and in contact with the lamp board 200 or the driving board 300.

[0040] In some embodiments, the connecting member 100 includes a connecting portion 102, and the two insertion ends 101 are respectively located at opposite ends of the connecting portion 102. At the same time, the cross-sectional area of the insertion end 101 is smaller than that of the connecting portion 102, so as to form an avoidance space 103 between the insertion end 101 and the connecting portion 102, so that the insertion end 101 can be inserted into the jack of the lamp board 200 or the driving board 300.

[0041] In some embodiments, the connecting portion 102 and the plug-in end 101 may adopt a cylindrical structure, and the cross-sectional area of the plug-in end 101 is smaller than that of the connecting portion 102, that is, the diameter of the connecting portion 102 is greater than that of the plug-in end 101, so that a clearance space 103 can be formed between the plug-in end 101 and the connecting portion 102. At the same time, the insertion holes of the lamp board 200 and the driving board 300 may adopt circular holes adapted to the plug-in end 101, so that the two plug-in ends 101 of the connector 100 can be respectively inserted into the insertion holes of the lamp board 200 and the driving board 300. At this time, the connector 100 can be connected to the lamp board 200 and the driving board 300 by means of threaded engagement or welding. The specific implementation manners have been explained and described in the above embodiments, and will not be repeated herein.

[0042] In some embodiments, the connecting portion 102 and the plug-in end 101 may adopt a rectangular sheet structure, and the connecting portion 102 has a pair of short sides and long sides arranged in pairs. The long side of the plug-in end 101 is vertically arranged on the short side of the connecting portion 102, and the cross-sectional area of the plug-in end 101 is smaller than that of the connecting portion 102, that is, the width of the connecting portion 102 is greater than that of the plug-in end 101, so that a clearance space 103 can be formed between the plug-in end 101 and the connecting portion 102. At the same time, the insertion holes of the lamp board 200 and the driving board 300 may adopt rectangular holes adapted to the plug-in end 101, so that the two plug-in ends 101 of the connector 100 can be respectively inserted into the insertion holes of the lamp board 200 and the driving board 300. At this time, the connector 100 can be connected to the lamp board 200 and the driving board 300 by means of welding. The specific implementation manners have been explained and described in the above embodiments, and will not be repeated herein.

[0043] In the above embodiments, the plug-in end 101 and the connecting portion 102 may adopt an integral structure, and the plug-in end 101, the connecting portion 102 and the clearance space 103 can be formed by cutting a rectangular metal plate. An arc chamfer is provided at the end of the plug-in end 101. At the same time, in order to ensure the strength of the connector 100, it is necessary to ensure that the thickness d of the connecting portion 102 is not less than 1 mm, and the ratio of the width b of the plug-in end 101 to the thickness d of the connecting portion 102 is not less than 2.5, that is, b≥2.5d, and the ratio of the width b of the connecting portion 102 to the thickness d of the connecting portion 102 is not less than 5. Of course, the plug-in end 101 and the connecting portion 102 may also adopt a split structure, that is, after the plug-in end 101 and the connecting portion 102 are respectively processed, the plug-in end 101 and the connecting portion 102 are connected by welding to form the connector 100.

[0044] In some embodiments, in order to facilitate the connection of the connector 100 to the lamp board 200 and the driver board 300 respectively by welding, the difference between the length c of the plug-in end 101 and the thickness d of the connecting portion 102 is not less than 2 mm, so that the operator can have a larger welding operation space to facilitate welding between the plug-in end 101 of the connector 100 and the lamp board 200 or the driver board 300 in the welding area 1011.

[0045] In some embodiments, the widths of the avoidance spaces 103 on both sides of the plug end 101 on the short side of the connector 100 are defined as h1 and h2, respectively, and the ratio of the width of the avoidance spaces 103 on both sides of the plug end 101 on the short side of the connector 100 to the thickness of the connecting portion 102 is not less than 1.5, that is, h1≥1.5d, and h2≥1.5d, so that the connector 100 can be limited to prevent the connector 100 from being disengaged from the sockets of the lamp board 200 and the driving board 300. At the same time, in order to make the force on the connector 100 more uniform, the plug end 101 is located in the middle area of the short side of the connecting portion 102, that is, the widths of the avoidance spaces 103 on both sides of the plug end 101 on the short side of the connector 100 are equal, h1 and h2.

[0046] In some embodiments, the length of the connecting portion 102 is not less than 3 mm, so that a gap of not less than 3 mm is formed between the lamp board 200 and the driving board 300, thereby ensuring a larger heat dissipation space for the lamp board 200. At the same time, it can avoid mechanical stress caused by temperature changes or other external factors, which may cause deformation or damage to the equipment. In addition, it can prevent electromagnetic interference and improve the stability and reliability of the car lights.

[0047] The connection structure for connecting the light board 200 and the driving board 300 provided in the present application is to cooperate with the sockets on the light board 200 and the driving board 300 respectively through the two plug-in ends 101 arranged opposite to each other on the conductive connecting member 100, so as to realize the electrical connection between the light board 200 and the driving board 300. As can be seen from the above examples, the connection structure provided in the present application is directly connected to the light board 200 and the driving board 300 through the two plug-in ends 101 of the conductive connecting member 100, which can reduce the number of parts, simplify the connection structure, and not only realize the reliable connection between the light board 200 and the driving board 300, but also reduce the space occupied in the vehicle lamp, reduce the cost, and reduce the volume of the vehicle lamp.

[0048] The embodiment of the present application also discloses a vehicle lamp, including a lamp board 200, a driving board 300 and a connecting structure for connecting the lamp board and the driving board as disclosed in the above embodiment. Therefore, the connecting structure has all the technical effects of the above-mentioned connecting structures, which will not be repeated herein.

[0049] In some embodiments, for the convenience of understanding, the jacks formed on the lamp board 200 are defined as first jacks 201, and the jacks formed on the driving board 300 are defined as second jacks 301. Moreover, the number of the first jacks 201 on the lamp board 200 is at least one, the number of the second jacks 301 on the driving board 300 is at least one, and the two plugging ends 101 of the connecting member 100 are respectively plugged into the first jack 201 and the second jack 301. It should be noted that the number of the first jacks 201 and the number of the second jacks 301 may be but are not limited to one, and may also be two, three or more, and the number of the connecting members 100 is adapted to the number of the first jacks 201 and the number of the second jacks 301.

[0050] In some embodiments, in order to ensure the firmness and reliability of the connection between the lamp board 200 and the driving board 300, the number of the first jacks 201 and the number of the second jacks 301 may be three. The central connection lines of the respective first jacks 201 enclose a triangular area, and the ratio between the area of the triangular area and the surface area of the lamp board 200 is not less than 40%. Meanwhile, the central connection lines of the respective second jacks 301 enclose a triangular area, and the ratio between the area of the triangular area and the surface area of the driving board 300 is not less than 40%. By connecting the three connecting members 100 to the three first jacks 201 of the lamp board 200 and the three second jacks 301 of the driving board 300 respectively, a triangular stable connection system is formed, thereby improving the firmness and reliability of the connection between the lamp board 200 and the driving board 300. It should be noted that the number of the first jacks 201 and the number of the second jacks 301 may also be four, and are respectively located at the four corners of the lamp board 200 and the driving board 300, and the four connecting members 100 are respectively connected to the four first jacks 201 of the lamp board 200 and the four second jacks 301 of the driving board 300. Of course, other distribution manners and numbers of the first jacks 201 and the second jacks 301 may also be adopted, which are not listed one by one herein.
