[0031] The present application is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] See also Figures 1 to 8 As shown; the embodiment of the present application discloses a car ground lamp, which is installed on the inner side of a car door, and its structure includes a shell 1, a circuit board 200 and a light-transmitting module 4. The shell 1 is provided with a plug interface 100, which is plugged with a plug of a power cord. The light-transmitting module 4 is a light-transmitting module 4 of the prior art, including a plurality of lenses distributed along the axial direction and a film with a pattern. The circuit board 200 is connected to an LED lamp 201 corresponding to the light-transmitting module 4; the light emitted by the LED lamp 201 enters through the light-inlet side of the light-transmitting module 4 and then is emitted through the light-outlet side of the light-transmitting module 4, and at the same time, the pattern on the film in the light-transmitting module 4 is projected onto the ground.

[0033] In this embodiment, if Figure 2 , Figure 3 and Figure 4 As shown, the housing 1 is connected with a back cover 2 that closes the housing 1, and the circuit board 200 is integrally formed on the inner side of the back cover 2; specifically, in this embodiment, the back cover 2 is made of metal material, that is, an aluminum substrate with good heat dissipation performance is used, and the circuit board 200 is integrated on the inner side of the aluminum substrate, so that the heat generated by the circuit board 200 can be better dissipated, thereby extending its use time and service life. The circuit board 200 is integrated with an LED lamp 201 and a socket 202, and the LED lamp 201 and the socket 202 are both electrically connected to the circuit board 200. The position of the LED lamp 201 corresponds to the light-incoming side of the light-transmitting module 4, and the back cover 2 is connected to the housing 1 by screws.

[0034] Furthermore, in this embodiment, in order to prevent water from entering the interior of the automobile floor lamp, an annular sealing groove 102 is provided on the assembly surface 101 where the housing 1 and the rear cover 2 are connected, and an annular sealing body 6 is connected in the annular sealing groove 102 to seal against the outer edge of the circuit board 200. Figure 5 As shown, after the rear cover 2 is connected to the housing 1 , the annular sealing body 6 provides good sealing performance between the rear cover 2 and the housing 1 , thereby effectively preventing water from entering the housing 1 .

[0035] In this embodiment, in order to make the rear cover 2 or the circuit board 200 and the housing 1 fit more compactly and to make the assembly efficiency between the two higher, at least one plug block 105 is provided on the assembly surface 101, and at least one slot 203 matching with the plug block 105 is provided on the rear cover 2; at least one plug post 106 is provided on the assembly surface 101, and at least one plug hole 204 matching with the plug post 106 is provided on the rear cover 2; the plug block 105 and the plug post 106 are respectively located on two opposite sides of the assembly surface 101. When the circuit board 200 is connected to the housing 1, the slot 203 on the circuit board 200 is matched with the plug block 105 on the housing 1, and the plug hole 204 on the circuit board 200 is matched with the plug post 106 on the housing 1 for insertion and positioning.

[0036] For example, Figure 6 and Figure 7 As shown, two plug blocks 105 are provided on one side of the assembly surface 101 of the shell 1, and two plug posts 106 are provided on the opposite side of the side; similarly, two slots 203 corresponding to the two plug blocks 105 are provided on one side of the back cover 2 or the circuit board 200, and two sockets 204 corresponding to the two plug posts 106 are provided on the other side.

[0037] In this embodiment, if Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the automobile ground lamp also includes a pin assembly, which includes a pin 5 and a positioning block 500 fixedly connected to the pin 5, the tail end of the pin 5 forms a connecting end 501, and the front end of the pin 5 forms a plug-in end 502; after the circuit board 200 is installed, the socket 202 on the circuit board 200 is matched with the connecting end 501 of the pin 5 for plugging and conduction; the housing 1 is provided with a mounting hole 104 connected to the plug interface 100, and the plug-in end 502 of the pin 5 passes through the mounting hole 104 and extends into the plug interface 100, forming a connector electrically connected to the plug of the power connection.

[0038] Further in this embodiment, Figure 5 , Figure 7 and Figure 8As shown, the pin assembly of the automobile ground lamp includes a pin 5 and a positioning block 500 fixedly connected to the pin 5. During assembly, the plug-in end 502 of the pin 5 of the pin assembly is passed through the mounting hole 104 of the housing 1 and extends into the plug-in port 100, and then the light-transmitting module 4 is installed, and finally the circuit board 200 is installed. When installing the circuit board 200, the socket 202 on the circuit board 200 is aligned with the connecting end 501 of the pin 5. After the circuit board 200 is installed, the socket 202 on the circuit board 200 is plugged and connected with the connecting end 501 of the pin 5. That is, in the present application, the pin assembly is an assembled structure, and the pin assembly is an integral part. When assembling the automobile ground lamp, it is only necessary to connect the pin assembly to the housing 1. After the light-transmitting module 4 and the circuit board 200 are installed, the pin assembly and the connection with the circuit board 200 can be completed. The pin assembly can be produced using an independent process, so that the precision of the pin assembly is relatively high, and the operation is simple and convenient during assembly, so that the automobile ground lamp is easy to assemble and the assembly efficiency is high. In addition, when repairing or replacing the pin 5, it is only necessary to disassemble the circuit board 200 and take out the pin assembly, which is simple and convenient to operate and will not damage the housing 1.

[0039] In this embodiment, in order to make the assembly of the pin assembly more convenient and simple, and to prevent the pin 5 from being offset when the circuit board 200 is connected to the connecting end 501 of the pin 5, as shown in FIG. Figure 7 As shown, a positioning groove 103 is provided in the housing 1, and the shape of the positioning groove 103 is adapted to the shape of the positioning block 500, and the positioning block 500 is loosely fitted in the positioning groove 103. That is, the positioning block 500 is limited in the positioning groove 103, so as to avoid the connection end 501 of the pin 5 from being offset, so that the position of the connection end 501 of the pin 5 is fixed. Specifically in this embodiment, there are two pins 5, and the connection ends 501 of the two pins 5 are bent upward and arranged perpendicular to the pin 5, that is, the pin 5 is bent in an L shape, and the positioning block 500 is a square-shaped positioning block 500. In this embodiment, the positioning block 500 is injection molded on the two pins 5, that is, the square positioning block 500 is injection molded on the pin 5, so that the two become one.

[0040] In some embodiments, a lampshade 400 corresponding to the light-emitting end of the light-transmitting module 4 is connected to the housing 1, and the lampshade 400 is ultrasonically welded to the housing 1. This makes the connection between the lampshade 400 and the housing 1 smoother, without burrs and flash.

[0041] It is not difficult to understand that the circuit board 200 and the LED will generate heat after working for a certain period of time, thereby increasing the temperature of the housing 1. If the hot air in the housing 1 is not discharged in time, it is easy to generate condensed water droplets in the housing 1 after contacting the cold air outside. In order to facilitate the timely discharge of the hot air in the housing 1, refer again to Figure 1 and Figure 4As shown, the housing 1 is provided with an air hole 107 communicating with the inner cavity of the housing 1, and the air hole 107 is connected with a waterproof breathable membrane 3. The waterproof breathable membrane 3 can discharge the hot air in the housing 1 to the outside and prevent external moisture or water vapor from entering the housing 1.

[0042] like Fig. 9 and Fig.10 As shown, in some embodiments, the automobile ground lamp further includes a reflective mask 7, which is detachably connected to the housing 1. The reflective mask 7 plays a reflective warning role. Specifically in this embodiment, a U-shaped plug-in portion 700 is provided on the reflective mask 7, and a plug-in slot 108 matching the plug-in portion 700 is provided on the housing 1, and a notch 701 is provided on the inner wall of the plug-in portion 700, and a clamping block 109 matching the notch 701 is provided in the plug-in slot 108. When the reflective mask 7 is plugged into the housing 1, the clamping block 109 is clamped in the notch 701. The reflective mask 7 is connected to the vehicle body. When installing the automobile ground lamp, it is only necessary to align the plug-in slot 108 on the shell 1 with the plug-in portion 700 of the reflective mask 7 and plug it into the reflective mask 7 to complete the installation of the automobile ground lamp. After the automobile ground lamp is installed, the block 109 in the plug-in slot 108 on the shell 1 is engaged with the notch 701 on the plug-in portion 700, so the automobile ground lamp can be firmly fixed to the reflective mask. The connection between the two does not require screws, and the installation is simple and convenient.
