[0026] Some embodiments of the application will be described in detail below with reference to the accompanying drawings. The following examples and features in the examples can be combined with each other without conflict.

[0027] As Figures 1 to 5As shown, one embodiment of the present application provides an in-vehicle lighting device, which comprises a light source module and a base 100. The base 100 is fixedly arranged at a predetermined position in the cabin system of the vehicle, such as the cabin roof, door panel interior, etc. The base 100 is provided with a fixing assembly 200, and a first accommodating groove 110 is formed on the base 100 for accommodating the light source module. The fixing assembly 200 is used to fix or release the light source module. In use, the state of the fixing assembly 200 can be switched according to the actual operation requirements, which not only provides protection for the stability of the assembled light source module, but also reserves convenience for subsequent disassembly operation. The light source module adopts a detachable design. When the light source module is assembled into the first accommodating groove 110, the fixing assembly 200 will be switched to a fixed state to stably limit the light source module, effectively avoiding displacement of the light source module due to vibration during vehicle driving. When the light source module needs to be disassembled, the fixing assembly 200 can be switched to a release state, so as to release the limitation of the light source module. The operator can easily take out the light source module without destructive operation on the base 100 or the cabin interior. The inner wall of the first accommodating groove 110 is provided with a first contact 540, and the light source module is provided with a second contact corresponding to the position of the first contact 540. The first contact 540 is pre-connected to the electric control system of the vehicle. When the light source module is assembled into the first accommodating groove 110 and the fixing assembly 200 completes the fixation of the light source module, the first contact 540 and the second contact are in contact and form an electrical connection. The electric control system of the vehicle can supply the light source module with the required power through the first contact 540 and the second contact. At the same time, the first contact 540 and the second contact serve as a bidirectional signal transmission channel, allowing the electric control system to send control instructions to the light source module and allowing the light source module to feed back working condition data to the electric control system.

[0028] The in-vehicle lighting device provided by the embodiment realizes detachable assembly of the light source module by arranging the first accommodating groove 110 and the fixing assembly 200 on the base 100, and the light source module can be easily fixed or removed without damaging the structure. At the same time, the first contact 540 of the first accommodating groove 110 and the second contact of the light source module are in contact and electrically connected after assembly. Through the detachable design combined with the contact type connection, the problem of traditional rigid installation of the in-vehicle lighting device which is difficult to disassemble and irreversible connection is solved, so that different functional light source modules can be replaced as needed without modifying the overall system, reducing the cost of functional expansion, making the in-vehicle lighting device better adapt to the demand of intelligent cabin, and breaking away from the limitation of traditional design.

[0029] In the optional implementation manner of the embodiment, Figure 1 and Figure 2As shown, the fixing assembly 200 is configured as a plurality; each fixing assembly 200 fixes the light source module in the first direction and the second direction; wherein the first direction is perpendicular to the second direction. By setting a plurality of fixing assemblies 200 in the first accommodating groove 110 and fixing the light source module in the first direction and the second direction perpendicular to each other, the module is stably limited in two perpendicular dimensions, avoiding the light source module from shifting and shaking in the first accommodating groove 110 due to vibration during vehicle driving, further ensuring the assembly stability.

[0030] In an optional embodiment of the present embodiment, as shown in Figure 1 and Figure 2 The fixing assembly 200 includes a first fixing member 210 for fixing the light source module in the first direction. Specifically, the first fixing member 210 includes a first base 211, a first elastic member 212 and a first telescopic member 213; the base 100 is provided with a first through hole 120 communicating with the first accommodating groove 110; the first base 211 is arranged on the base 100 and located at one end of the first through hole 120 away from the first accommodating groove 110, and the first base 211 can be connected to the base 100 by screws; a hole is formed in the first base 211, and the first telescopic member 213 is slidingly arranged on the first base 211 and further passes through the first through hole 120 after being connected to the base 100; the first telescopic member 213 can slide on the first base 211 in the first direction to extend into or exit from the first accommodating groove 110, thereby realizing the fixation or release of the light source module; the first elastic member 212 is a spring, which is sleeved on the first telescopic member 213, with one end abutting against the first base 211 and the other end abutting against a limiting ring on the first telescopic member 213; the first elastic member 212 is used to provide a driving force for the first telescopic member 213 to extend into the first accommodating groove 110, so as to stably limit the light source module.

[0031] In the present embodiment, the first telescopic member 213 has a rod-like structure, when the first telescopic member 213 slides in the first direction to extend into the first accommodating groove 110, the first telescopic member 213 can be inserted into the corresponding hole on the light source module to fix the light source module; when the first telescopic member 213 slides in the first direction to exit from the first accommodating groove 110, the first telescopic member 213 exits from the corresponding hole on the light source module to release the light source module. Preferably, the end of the first telescopic member 213 is spherical or frustoconical, thereby playing a certain guiding role to facilitate the installation and disassembly of the light source module, avoiding the damage of the first telescopic member 213 or the light source module caused by the rigid contact between the first telescopic member 213 and the light source module.

[0032] Further, as shown in Figure 1 and Figure 2As shown, the first fixing member 210 is configured as two; two first fixing members 210 are arranged on the opposite sides of the first accommodating groove 110 along the first direction. By arranging two opposite first fixing members 210, the stability of the light source module in the first direction can be improved.

[0033] In an alternative embodiment of the present embodiment, as shown in Figures 1 to 5 As shown, the fixing assembly 200 comprises a second fixing member 220 for fixing the light source module in the second direction. Specifically, the second fixing member 220 comprises a second base 221, a second elastic member 222 and a second telescopic member 223; the base 100 is provided with a second through hole 130 communicating with the first accommodating groove 110; the second base 221 is arranged on the base 100 and located at the end of the second through hole 130 away from the first accommodating groove 110, and the second base 221 can be connected to the base 100 by screws; the second base 221 is provided with a hole, and the second telescopic member 223 is slidingly arranged on the second base 221 and also passes through the second through hole 130 after the second base 221 is connected to the base 100; the second telescopic member 223 can slide on the second base 221 along the second direction to extend into or exit the first accommodating groove 110, thereby realizing the fixing or releasing of the light source module; the second elastic member 222 is a spring, which is sleeved on the second telescopic member 223, with one end abutting against the second base 221 and the other end abutting against a limiting ring on the second telescopic member 223, and the second elastic member 222 is used to provide a driving force for the second telescopic member 223 to extend into the first accommodating groove 110, so as to stably position the light source module.

[0034] In the present embodiment, the second telescopic member 223 has a rod-like structure, and when the second telescopic member 223 slides along the second direction to extend into the first accommodating groove 110, the second telescopic member 223 can also be inserted into the insertion hole at the corresponding position of the light source module to fix the light source module; when the second telescopic member 223 slides along the second direction to exit the first accommodating groove 110, the second telescopic member 223 also exits the insertion hole at the corresponding position of the light source module to release the light source module. Preferably, the end of the second telescopic member 223 is spherical or frustoconical, thereby playing a certain guiding role to facilitate the installation and disassembly of the light source module, avoiding the rigid contact between the second telescopic member 223 and the light source module to cause damage to the second telescopic member 223 or the light source module, and improving the service life.

[0035] In other alternative embodiments of the present embodiment, the fixing assembly 200 can also be a permanent magnet or an electromagnet, which can fix the light source module by adsorption, and can also achieve the purpose of detachable assembly of the light source module in the first accommodating groove 110 in the present embodiment.

[0036] In an alternative embodiment of the present embodiment, as shown in Figures 1 to 5As shown, a pressing member 300 is also included; the base 100 is further provided with a second accommodating groove 140, which is spaced apart from the first accommodating groove 110, and the second through-hole 130 passes through the second accommodating groove 140 and is also communicated with the second accommodating groove 140. In this way, when the second telescopic member 223 is inserted into the second through-hole 130, the second telescopic member 223 is also located in the second accommodating groove 140; the pressing member 300 is slidably arranged in the second accommodating groove 140, and the pressing member 300 slides in the second accommodating groove 140 along the depth direction of the second accommodating groove 140, and the pressing member 300 is also connected to the portion of the second telescopic member 223 located in the second accommodating groove 140. When in use, by pressing the pressing member 300, the pressing member 300 slides along the depth direction of the second accommodating groove 140, which can cause the second telescopic member 223 to exit the first accommodating groove 110 to release the light source module, thereby realizing rapid disassembly of the light source module.

[0037] When the pressing member 300 is assembled in the second accommodating groove 140, the protrusions are located in the corresponding slide grooves, and the pressing member 300 can slide in the second accommodating groove 140 along the depth direction of the second accommodating groove 140; a third sliding piece corresponding to the second sliding piece is further provided in the second accommodating groove 140, and the second sliding piece and the third sliding piece are both provided with limiting grooves, which also extend along the depth direction of the second accommodating groove 140. When the pressing member 300 is assembled in the second accommodating groove 140, the corresponding limiting grooves are connected to facilitate the assembly of the pressing member 300, and play a certain guiding role in the assembly of the pressing member 300, and ensure the stability of the pressing member 300 during use.

[0038] In this embodiment, the pressing member 300 is further provided with an extrusion piece 310; the second telescopic member 223 is provided with an elongated hole 224. The end of the extrusion piece 310 is inclined away from the first accommodating groove 110, and the end portion of the extrusion piece 310 can extend into the elongated hole 224. When the pressing member 300 is pressed, the pressing member 300 slides along the depth direction of the second accommodating groove 140, and the portion of the extrusion piece end extending into the elongated hole 224 begins to increase. The inclined portion begins to press the inner edge of the elongated hole 224, thereby causing the second telescopic member 223 to slide in the second direction and exit the first accommodating groove 110. When not in use, under the action of the second elastic member 222, the elongated hole 224 pushes the end of the extrusion piece, allowing the pressing member 300 to return to its original position.

[0039] In an optional implementation of this embodiment, if Figure 3As shown, a guide hole 150 is further provided on the base 100. The guide hole 150 is provided protruding from the surface of the base 100. The guide hole 150 is connected to the end of the second through hole 130 away from the second accommodating groove 140. By providing the guide hole 150, on the one hand, it can facilitate the assembly of the second fixing member 220 and play a certain guiding role on the second telescopic member 223. On the other hand, it can also prevent the second telescopic member 223 from escaping from the second through hole 130.

[0040] In an optional implementation of this embodiment, if Figure 1 and Figure 2 As shown, it also includes a pushing mechanism 400; the pushing mechanism 400 is arranged on the base 100 and is against the light source module; when the pressing member 300 is pressed to make the second telescopic member 223 withdraw from the first accommodating groove 110, the pushing mechanism 400 can push the light source module to push the light source module out of the first accommodating groove 110.

[0041] In this embodiment, the ejection mechanism 400 includes an ejection assembly 410 and an ejector sleeve 420. The ejection assembly 410 pushes the light source module using a preset elastic force. After the light source module is released, it can provide a thrust in the direction of removal, allowing the light source module to be removed from the first receiving groove 110. The ejection assembly 410 includes a spring and an ejector, with the ejector sleeve 420 assembled to the end of the ejector. The ejection mechanism 400 is disposed on the back side of the base 100, which is the side of the base 100 facing away from the receiving groove. The bottom wall of the first receiving groove 110 is provided with an ejection hole, into which the ejector and ejector sleeve 420 are inserted. When the light source module is installed, the light source module presses against the ejector and ejector sleeve 420, compressing the spring. After the second telescopic member 223 is released, the spring rebounds and pushes the ejector and ejector sleeve 420, which push the light source module out of the first receiving groove 110. The first telescopic members 213 of the two first fixing members 210 have a short stroke, so the elastic force of the spring of the pushing assembly 410 can overcome the resistance of the two first telescopic members 213 to the light source module and push the light source module out of the first accommodating groove 110 .

[0042] In an optional implementation of this embodiment, if Figure 1 and Figure 2As shown, the automobile interior lighting device further comprises a wiring assembly 500; the wiring assembly 500 comprises a third base 510, a plug-in piece 520, a wire harness 530 and a first contact 540; the plug-in piece 520, the wire harness 530 and the first contact 540 are fixedly arranged on the third base 510, and the third base 510 is detachably mounted on the back of the base 100 through clamping or screw connection; the plug-in piece 520 is used for electrical connection with the automobile, and the first contact 540 is electrically connected with the plug-in piece 520 through the wire harness 530; the inner wall of the first accommodating groove 110 is provided with a third through hole 160 corresponding to the position of the first contact 540, and when the base is connected with the base 100, the first contact 540 is located in the third through hole 160.
