Abstract

A light-transmitting assembly and a vehicle are provided in the disclosure. The light-transmitting assembly includes a light-transmitting substrate and a light source assembly. The light-transmitting substrate defines a mounting through-hole. The light source assembly is connected to the light-transmitting substrate and positioned at the mounting through-hole. The light source assembly includes a box, a lampshade, and a light-emitting element. The lampshade is detachably connected to the box. The lampshade and the box cooperatively define an accommodating space. The light-emitting element is received in the accommodating space. The light-transmitting assembly of the disclosure can be assembled and disassembled quickly and repeatedly, thereby realizing quick replacement of the light-emitting element.

First claim

What is claimed is:

1 . A light-transmitting assembly, comprising:

2 . The light-transmitting assembly of claim 1 , wherein
the first fitting portion is a groove and the second fitting portion is a hook, or the first fitting portion is a hook and the second fitting portion is a groove; and the box is snap-fitted with the lampshade through the groove and the hook.

3 . The light-transmitting assembly of claim 1 , wherein the light source assembly further comprises a sealing ring arranged between the lampshade and the box to enable the lampshade to be in sealed connection with the box.

4 . The light-transmitting assembly of claim 1 , wherein the lampshade comprises a lampshade body and a first limiting portion protruding from the lampshade body, the box comprises a box body and a second limiting portion protruding from the box body, the light-transmitting substrate is arranged between the first limiting portion and the second limiting portion, and the first fitting portion and the second fitting portion cooperate to detachably connect the box, the lampshade, and the light-transmitting substrate together.

5 . The light-transmitting assembly of claim 4 , wherein the light source assembly further comprises a sealing ring, wherein the lampshade, the box, and the light-transmitting substrate cooperatively define a gap therebetween, and the sealing ring extends into the gap to enable the lampshade, the box, and the light-transmitting substrate to be in sealed connection with one another.

6 . The light-transmitting assembly of claim 5 , wherein part of the box body extends into the mounting through-hole, the part of the box body and the light-transmitting substrate cooperatively define a first gap therebetween, and the sealing ring extends into the first gap and abuts against both the first limiting portion and the second limiting portion.

7 . The light-transmitting assembly of claim 5 , wherein the second limiting portion is positioned at one side of the light-transmitting substrate, and the second limiting portion and the light-transmitting substrate cooperatively define a second gap therebetween; the first limiting portion is positioned at another side of the light-transmitting substrate, part of the box body extends into the mounting through-hole, and the part of the box body and the first limiting portion cooperatively define a third gap therebetween; and the sealing ring further extends into at least one of the second gap or the third gap.

8 . The light-transmitting assembly of claim 4 , wherein the first fitting portion is farther away from the light-transmitting substrate than both the first limiting portion and the second limiting portion, and the second fitting portion is farther away from the light-transmitting substrate than both the first limiting portion and the second limiting portion.

9 . The light-transmitting assembly of claim 4 , wherein the first limiting portion is positioned at one side of the light-transmitting substrate, and all of the second limiting portion, the first fitting portion, and the second portion are positioned at the other side of the light-transmitting substrate.

10 . The light-transmitting assembly of claim 1 , wherein the mounting through-hole is implemented as one or more mounting through-holes, the light source assembly is implemented as one or more light source assemblies, a number of the one or more mounting through-holes is equal to a number of the one or more light source assemblies, and the one or more light source assemblies are in one-to-one correspondence with the one or more mounting through-holes, and each of the one or more light source assemblies faces a corresponding mounting through-hole.

11 . The light-transmitting assembly of claim 1 , wherein the light-transmitting substrate comprises at least two light-transmitting sub-substrates, the mounting through-hole is implemented into one or more mounting through-holes, and each of the one or more mounting through-holes is defined between two adjacent light-transmitting sub-substrates.

12 . The light-transmitting assembly of claim 1 , wherein the light source assembly further comprises:
a harness joint in communication with the light-emitting element and a vehicle controller, wherein the harness joint is configured to receive a control signal sent by the vehicle controller and transmit the control signal to the light-emitting element to control the light-emitting element to emit light of a preset pattern.

13 . The light-transmitting assembly of claim 1 , wherein the lampshade extends through the mounting through-hole, and the box extends through the mounting through-hole.

14 . A vehicle, comprising a light-transmitting assembly and a vehicle body, the light-transmitting assembly being fixed to the vehicle body, and the light-transmitting assembly comprising a light-transmitting substrate and a light source assembly, wherein
the light-transmitting substrate defines a mounting through-hole; and the light source assembly is connected to the light-transmitting substrate and positioned at the mounting through-hole, wherein the light source assembly comprises a lampshade, a box, and a light-emitting element, the lampshade is detachably connected to the box, the lampshade and the box cooperatively define an accommodating space, and the light-emitting element is received in the accommodating space; wherein the lampshade is fixedly connected to the light-transmitting substrate and formed at the mounting through-hole through injection molding; or the box is fixedly connected to the light-transmitting substrate and formed at the mounting through-hole through injection molding wherein the lampshade has a first fitting portion, the box has a second fitting portion, and the first fitting portion and the second fitting portion mate with each other to enable the lampshade to be detachably connected to the box.
