DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0044] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0045] The following is a detailed description of the automobile ground lamp provided in the embodiment of the present application through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0046] like Figures 1 to 12 As shown, an embodiment of the present application provides a vehicle ground lamp, including a main mounting frame 200, a switching bracket 300 rotatably arranged on the main mounting frame 200, and an imaging lens group 500 and a light-emitting unit fixedly arranged on the main mounting frame 200, and a plurality of film sheets 400 are fixedly arranged on the switching bracket 300 in a circular array along its own rotation axis.

[0047] A light passage is formed through the main mounting frame 200 , and the imaging lens assembly 500 is fixedly disposed in the light passage. The light emitting unit is located at one end of the light passage and can emit a light beam to the imaging lens assembly 500 .

[0048] Among them, the main mounting frame 200 is provided with a switching groove 210 which is radially connected to the light transmission channel and passes through the light transmission channel. The film 400 can enter or leave the light transmission channel through the switching groove 210 as the switching bracket 300 rotates. When the film 400 is located in the light transmission channel, the light beam emitted by the light-emitting unit can pass through the imaging lens group 500 and the film 400 along the light transmission channel, thereby forming a pattern on the film 400 at the corresponding position on the projection surface.

[0049] It is understandable that the corresponding patterns on the multiple film sheets 400 are different. As the switching bracket 300 rotates, the film sheets 400 with different patterns enter the light passage through the switching slot 210 and are located on the light path of the light-emitting unit, thereby realizing the switching of different patterns on the projection surface.

[0050] In an embodiment of the present application, the above-mentioned automobile floor lamp is adopted. By rotating the switching bracket 300, the film 400 expressing different patterns can be moved to the light path of the light-emitting unit. When the light beam emitted by the light-emitting unit passes through the imaging lens group 500 and the film 400, a corresponding pattern can be formed on the projection surface. Not only can the switching of multiple projection patterns be realized, but the structure is simple, thereby reducing the overall cost of the pattern-switchable floor lamp.

[0051] It can be understood that the switching bracket 300 can be rotatably set on the main mounting frame 200, and the main mounting frame 200 and the switching bracket 300 can also be set as a split structure, that is, the switching bracket 300 is rotatably set on an external mounting frame. At this time, the switching of the film 400 in the light passage of the main mounting frame 200 can also be achieved through the rotation of the switching bracket 300. As long as the rotation relationship of the switching bracket 300 relative to the main mounting frame 200 can be guaranteed, it will not be elaborated here.

[0052] In a preferred embodiment, Figures 1 to 3As shown, the switching bracket 300 includes a switching shaft 310 rotatably set on the main mounting frame 200 and a rotating frame 320 fixedly set on the switching shaft 310, and the rotating frame 320 includes a plurality of circular support plates arranged in a circular array along the axis of the switching shaft 310, and a light-through hole 323 is formed through the circular support plate, and the film 400 is fixedly set on the circular support plate and is located at a position corresponding to the light-through hole 323.

[0053] It can be understood that when the switching shaft 310 rotates relative to the main mounting frame 200, the circular support plate on the rotating frame 320 can enter the light passage through the switching groove 210. As the rotation angle of the switching shaft 310 is adjusted, the film 400 carrying different patterns can be transferred to the light path of the light-emitting unit, thereby realizing the transformation of various projection patterns.

[0054] It is understandable that the setting form of the rotating rack 320 is not limited to the above-mentioned one. For example, the switching bracket 300 can also be set to a disc shape, and the film 400 is fixedly arranged in a circular array on the disc structure about the axis of the switching shaft 310. As long as the switching of different films 400 in the light-transmitting channel can be achieved with the rotation of the switching shaft 310, it will not be elaborated here.

[0055] In a preferred embodiment, Figures 1 to 3 As shown, the circular support plate of the wheel-changing frame 320 is loosely matched with the switching slot 210 .

[0056] It can be understood that, through the clearance fit between the circular support plate and the switching slot 210, when the circular support plate enters the light-transmitting channel, the connecting space between the light-transmitting channel and the outside world at the switching slot 210 can be reduced, thereby reducing the leakage of light in the light-transmitting channel and improving the projection effect of the pattern.

[0057] In a preferred embodiment, Figures 1 to 3 As shown, a groove 322 communicating with the light through hole 323 is provided on one side end surface of the rotating rack 320 at a position corresponding to the light through hole 323 , and the film 400 is embedded in the groove 322 .

[0058] The switch bracket 300 further includes a pressure ring 340 fixedly disposed on the wheel-changing frame 320 at a position corresponding to the embedding groove 322 . The pressure ring 340 can press against an end surface of the film 400 at a corresponding position away from the wheel-changing frame 320 to limit the axial displacement of the film 400 about the switch shaft 310 .

[0059] It is understandable that the method of fixing the film 400 on the rotating rack 320 is not limited to the above-mentioned one. For example, the film 400 can be directly bonded to the rotating rack 320. As long as the film 400 can be fixedly installed on the rotating rack 320, it will not be elaborated here.

[0060] In a preferred embodiment, Figures 1 to 3 As shown, a first positioning pin 321 is fixedly provided on the circular support plate of the wheel-changing frame 320 , and a first positioning hole 341 which can be engaged with the first positioning pin 321 is formed through the pressure ring 340 .

[0061] It can be understood that when the pressure ring 340 is installed on the circular support plate of the wheel-changing frame 320, the installation positioning and guiding of the pressure ring 340 can be achieved through the engagement of the first positioning hole 341 with the first positioning pin 321 at the corresponding position, thereby improving the overall assembly efficiency of the switching bracket 300.

[0062] In a preferred embodiment, Figure 1 , Figure 2 As shown, it also includes a driving assembly 100 for driving the switching bracket 300 to rotate relative to the main body mounting bracket 200.

[0063] In an embodiment of the present application, the above-mentioned automobile ground lamp is adopted, and the driving component 100 can be set to perform mode association or establish independent module control through an interconnected vehicle computer, so as to realize the control of the working state of the driving component 100, and then realize the adjustment of the projection pattern of the device.

[0064] In a preferred embodiment, Figure 1 , Figure 2 As shown, the driving assembly 100 includes a motor 110 fixedly mounted on an external mounting frame, a rotating shaft 120 is fixedly mounted on a power output end of the motor 110 , and a worm portion 121 is disposed on the rotating shaft 120 .

[0065] Among them, the switching shaft 310 is provided with a tooth portion 330 meshing with the worm portion 121. When the motor 110 drives the rotating shaft 120 to rotate, the worm portion 121 meshes with the tooth portion 330 and drives the switching shaft 310 and the wheel changing frame 320 to rotate synchronously, thereby realizing the position change of the film 400 on the switching bracket 300.

[0066] It is understandable that the structural form of the drive component 100 is not limited to the above-mentioned one. For example, the switching shaft 310 can be configured such that the power output end is directly fixedly connected to the switching shaft 310. This configuration will increase the space occupied in the axial direction of the switching shaft 310 and affect the layout of the device. As long as the rotational drive of the switching bracket 300 can be achieved, it will not be elaborated here.

[0067] In a preferred embodiment, Figure 1 , Figure 2 , Fig.12 As shown, the light-emitting unit includes a PCB board 600 fixedly mounted on the main mounting frame 200 and covering one end of the light-transmitting channel, and a light source component 610 is fixedly mounted on an end surface of the PCB board 600 close to the main mounting frame 200.

[0068] The light source component 610 can emit a light beam to the imaging lens group 500 and the film 400 in the light transmission channel. After the light beam passes through the light transmission channel, it can form a projection corresponding to the pattern carried by the film 400 at a predetermined position.

[0069] In a preferred embodiment, Figure 1 , Figure 2 , Fig.12 As shown, a second positioning hole 620 is formed through the PCB board 600 , and a positioning pin capable of engaging with the second positioning hole 620 is fixedly provided on the end surface of the main mounting frame 200 close to the PCB board 600 .

[0070] In a preferred embodiment, Figure 1 , Figure 2 , Fig.12 As shown, the PCB board 600 is provided with a through hole 630 for wiring on the PCB board 600 to pass through.

[0071] In a preferred embodiment, Figure 1 , Figure 2 , Figures 5 to 11 As shown, the main mounting frame 200 includes a fixing frame 220 and a first mirror frame and a second mirror frame fixedly disposed on the fixing frame 220 , and the first mirror frame and the second mirror frame are axially spaced apart from each other with respect to the fixing frame 220 .

[0072] The switching slot 210 is specifically the interval between the first frame and the second frame, the light passage passes through the first frame and the second frame, and the imaging lens group 500 is fixedly arranged in the first frame and / or the second frame.

[0073] In the embodiment of the present application, the above-mentioned automobile ground lamp is adopted, and a modular assembly structure is adopted. On the one hand, the overall assembly efficiency of the device can be improved. On the other hand, through the cooperation of the first mirror frame, the second mirror frame and the rotating frame 320, the light leakage of the light channel can be reduced to a large extent, thereby reducing the light loss passing through the imaging lens group 500 and the film 400, thereby improving the projection imaging effect.

[0074] In a preferred embodiment, Figure 4 As shown, the imaging lens assembly 500 includes a first lens 510, a second lens 520, and a third lens 530 disposed in a second lens frame.

[0075] In a preferred embodiment, Figure 1 , Figure 2 , Figures 6 to 8 As shown, the first frame includes a first embedding portion 230 and a first cover portion 250 connected to the first embedding portion 230 .

[0076] The first embedded portion 230 is axially provided with a first transparent cavity 231 opening toward the first cover portion 250 . The inner wall of the first transparent cavity 231 is provided with a first arc groove 232 which is embedded with the first lens 510 and is semicircular, and a second arc groove 233 which is embedded with the second lens 520 and is semicircular.

[0077] A second cavity 251 is axially formed on the first cover portion 250 and opens toward the first embedded portion 230 . A third arc groove 252 and a semicircular arc groove 253 are formed on the inner wall of the second cavity 251 and are embedded with the first lens 510 and are embedded with the second lens 520 .

[0078] The first embedded portion 230 and the first cover portion 250 are buckled with each other, the first arc groove 232 and the third arc groove 252 are corresponding in position and connected to each other, and the second arc groove 233 and the fourth arc groove 253 are corresponding in position and connected to each other.

[0079] It can be understood that during assembly, the first lens 510 and the second lens 520 are first embedded in the first arc groove 232 and the second arc groove 233, and then the first cover part 250 is installed on the first embedded part 230, and the first lens 510 and the second lens 520 are further embedded in the third arc groove 252 and the fourth arc groove 253. At the same time, the first transparent cavity 231 and the second transparent cavity 251 are combined to form a partial light-transmitting channel.

[0080] Of course, the first lens 510 and the second lens 520 can also be embedded in the third arc groove 252 and the fourth arc groove 253 first, and then the first embedding part 230 can be installed on the first cover part 250. As long as the first lens 510 and the second lens 520 can be installed in the first embedding part 230 and the first cover part 250, it will not be elaborated here.

[0081] It can be understood that the reason why the first arc groove 232, the second arc groove 233, the third arc groove 252, and the fourth arc groove 253 are set as semicircular grooves is to ensure that the opening radius of the first arc groove 232, the second arc groove 233, the third arc groove 252, and the fourth arc groove 253 corresponds to the radius of the first lens 510 and the second lens 520, so as to achieve complete embedding of the first lens 510 and the second lens 520 on the first frame.

[0082] In a preferred embodiment, Figure 1 , Figure 2 , Figures 6 to 8 As shown, a guide post 235 is fixedly provided on the end surface of the first embedded portion 230 close to the first cover portion 250 , and a guide hole 257 which is embedded with the guide post 235 is provided on the end surface of the first cover portion 250 close to the first embedded portion 230 .

[0083] In a preferred embodiment, Figure 1 , Figure 2 , Figures 6 to 8 As shown, a first positioning convex groove 237 is provided on the end surface of the first embedded portion 230 close to the first cover portion 250 , and a first positioning convex portion 259 engaged with the first positioning convex groove 237 is fixedly provided on the end surface of the first cover portion 250 close to the first embedded portion 230 .

[0084] It can be understood that, through the interlocking cooperation between the first positioning groove 237 and the first positioning protrusion 259, on the one hand, the installation of the first embedded portion 230 and the first cover portion 250 can be guided, and on the other hand, the radial displacement of the first embedded portion 230 and the first cover portion 250 along the abutting surface can be limited, thereby ensuring the installation stability of the first frame.

[0085] In a preferred embodiment, Figure 1 , Figure 2 , Figures 6 to 8 As shown, a first paving groove 234 is provided on an end surface of the first embedding portion 230 close to the PCB board 600 , and a second paving groove 256 is provided on an end surface of the first cover portion 250 close to the PCB board 600 .

[0086] When the first embedding portion 230 and the first cover portion 250 are in a connected state, the first clearance groove 234 and the second clearance groove 256 form an escape space for electronic components on the PCB board 600 .

[0087] In a preferred embodiment, Figure 1 , Figure 2 , Figures 6 to 8 , Fig.12 As shown, a second positioning pin 236 is fixedly disposed on one end of the first embedding portion 230 close to the PCB board 600 , and a third positioning pin 258 is fixedly disposed on one end of the first cover portion 250 close to the PCB board 600 .

[0088] A plurality of second positioning holes 620 are formed on the PCB board 600 at positions corresponding to the second positioning pins 236 and the third positioning pins 258 , and the plurality of second positioning holes 620 are respectively plugged with the second positioning pins 236 and the third positioning pins 258 .

[0089] In a preferred embodiment, Figure 1 , Figure 2 , Figures 6 to 8 As shown, two first connecting ears 254 are symmetrically and fixedly disposed on the first cover portion 250 about the central axis.

[0090] The first embedded portion 230 abuts against the fixing frame 220 , and the first cover portion 250 is bolted to the fixing frame 220 via the first connecting ear 254 .

[0091] It is understandable that, when the first cover portion 250 is fixedly connected to the fixing frame 220 , the first embedded portion 230 is located between the first cover portion 250 and the fixing frame 220 and the relative position between the first cover portion 250 and the fixing frame 220 is fixed.

[0092] In a preferred embodiment, Figure 1 , Figure 2 , Figure 6 As shown, a first connecting frame 255 is fixedly provided on the first cover portion 250 , and the switching shaft 310 is rotatably provided on the first connecting frame 255 .

[0093] In a preferred embodiment, Figure 4 , Figure 7 , Figure 8 As shown, a limiting groove 238 is provided on the inner wall of the second arc groove 233 , and a limiting protrusion 521 capable of being embedded in the limiting groove 238 is fixedly provided on the second lens 520 .

[0094] It is understandable that when the second lens 520 is embedded in the second arc groove 233, the engagement between the limiting protrusion 521 and the limiting groove 238 can limit the axial and circumferential displacement of the second lens 520 along the first embedding portion 230, thereby achieving the positioning of the second lens 520 in the second arc groove 233.

[0095] Of course, the limiting groove 238 can also be set on the fourth arc groove 253, as long as it can achieve the limitation of the second lens 520, which is not elaborated here.

[0096] In a preferred embodiment, Figure 1 , Figure 2 , Figures 9 to 11 As shown, the second frame includes a second embedding portion 240 and a second cover portion 260 connected to the second embedding portion 240 .

[0097] A third cavity 241 is formed on the second embedding portion 240 along the axial direction and opens toward the second cover portion 260 . A fifth arc groove 242 in a semicircular shape and embedded with the third lens 530 is formed on the inner wall of the third cavity 241 .

[0098] A fourth cavity 261 is formed on the second cover portion 260 along the axial direction and opens toward the second embedding portion 240 . A sixth arc groove 262 in a semicircular shape and embedded with the third lens 530 is formed on the inner wall of the fourth cavity 261 .

[0099] The second embedding portion 240 and the second cover portion 260 are buckled with each other, and the fifth arc groove 242 and the sixth arc groove 262 are located correspondingly and are connected to each other.

[0100] It can be understood that during assembly, the third lens 530 is first embedded in the fifth arc groove 242, and then the second cover part 260 is installed on the second embedded part 240, and the third lens 530 is further embedded in the sixth arc groove 262. At the same time, the third transparent cavity 241 and the fourth transparent cavity 261 are combined to form a partial light-transmitting channel.

[0101] Of course, the third lens 530 may be first embedded in the sixth arc groove 262 and then the second embedding portion 240 may be installed on the second cover portion 260. As long as the third lens 530 can be installed in the second embedding portion 240 and the second cover portion 260, it will not be elaborated here.

[0102] It is understandable that the reason why the fifth arc groove 242 and the sixth arc groove 262 are set as semicircular grooves is to ensure that the opening radius of the fifth arc groove 242 and the sixth arc groove 262 corresponds to the radius of the third lens 530, thereby achieving complete embedding of the third lens 530 on the second frame.

[0103] In a preferred embodiment, Figure 1 , Figure 2 , Figures 9 to 11 As shown, a second positioning convex groove 243 is provided on the end surface of the second embedding portion 240 close to the second cover portion 260 , and a second positioning convex portion 265 engaged with the second positioning convex groove 243 is fixedly provided on the end surface of the second cover portion 260 close to the second embedding portion 240 .

[0104] It can be understood that, through the interlocking cooperation of the second positioning groove 243 and the second positioning protrusion 265, on the one hand, the installation of the second embedded portion 240 and the second cover portion 260 can be guided, and on the other hand, the radial displacement of the second embedded portion 240 and the second cover portion 260 along the abutment surface can be limited, thereby ensuring the installation stability of the first frame.

[0105] In a preferred embodiment, Figure 1 , Figure 2 , Fig. 9 As shown, two second connecting ears 263 are symmetrically and fixedly provided on the second cover portion 260 about the central axis.

[0106] The second embedded portion 240 abuts against the fixing frame 220 , and the second cover portion 260 is bolted to the fixing frame 220 via the second connecting ear 263 .

[0107] It is understandable that, when the second cover portion 260 is fixedly connected to the second embedded portion 240 , the second embedded portion 240 is located between the second cover portion 260 and the fixing frame 220 and the relative position between the second cover portion 260 and the fixing frame 220 is fixed.

[0108] In a preferred embodiment, Figure 1 , Figure 2 , Fig. 9 As shown, a second connecting frame 264 is fixedly provided on the second cover portion 260 , and the switching shaft 310 is rotatably provided on the second connecting frame 264 .

[0109] It is understandable that the second connecting frame 264 corresponds to the first connecting frame 255 in position, and one end of the switching shaft 310 is rotatably connected to the first connecting frame 255 , and the other end is rotatably connected to the second connecting frame 264 .

[0110] During installation, first install the second mirror frame on the fixed frame 220, then rotate and install the switching bracket 300 on the first connecting frame 255, and finally install the first mirror frame on the fixed frame 220, so that the switching bracket 300 is further rotationally connected with the second connecting frame 264, thereby realizing the installation and limiting of the switching bracket 300.

[0111] In a preferred embodiment, Figure 1 , Figure 2 , Figure 5 As shown, a receiving cavity 223 is axially penetrated on the fixing frame 220 and opened toward the side close to the switching bracket 300. The first cover portion 250 and the second cover portion 260 are fixedly connected to the fixing frame 220. The first embedded portion 230 and the second embedded portion 240 are located in the receiving cavity 223 and respectively abut against the inner wall of the receiving cavity 223.

[0112] In a preferred embodiment, Figure 5 , Figure 8 , Fig.11 As shown, a limiting guide rail 222 is fixedly provided on the inner wall of the accommodating cavity 223 away from the switching bracket 300 .

[0113] A first slide groove 239 which can be plugged into the limiting guide rail 222 is axially provided on the outer circumference of the first embedded portion 230 away from the first cover portion 250 , and a second slide groove 244 which can be plugged into the limiting guide rail 222 is axially provided on the outer circumference of the second embedded portion 240 away from the second cover portion 260 .

[0114] The first slide groove 239 is connected to one end of the first embedded portion 230 near the second frame, and the two ends of the second slide groove 244 along the axial direction of the second embedded portion 240 are connected to the corresponding side end surfaces of the second embedded portion 240 respectively.

[0115] When the first mirror frame and the second mirror frame are installed on the fixed frame 220, the second slide groove 244 on the second embedded portion 240 is first inserted into the limiting guide rail 222 along the axial direction of the fixed frame 220 until the second embedded portion 240 moves to abut against the inner wall of the accommodating cavity 223 on the side away from the PCB board 600, and the second mirror frame is positioned; then the first slide groove 239 on the first embedded portion 230 is inserted into the limiting guide rail 222 along the axial direction of the fixed frame 220 until the first slide groove 239 abuts against the inner wall of the side away from the second mirror frame and the limiting guide rail 222 on the side close to the PCB board 600, and the first mirror frame is positioned, and a gap is formed between the first mirror frame and the second mirror frame, and the gap is specifically the switching groove 210.

[0116] In a preferred embodiment, Figure 5 , Figure 8 , Fig.11 As shown, the limiting guide rail 222 is specifically configured to be ladder-shaped, with a narrow end at one side close to the PCB board 600 and a wide end at one side away from the PCB board 600.

[0117] The first sliding groove 239 and the second sliding groove 244 are configured as trapezoidal grooves corresponding to the shape of the installation position limiting guide rail 222 .

[0118] It can be understood that, through the ladder-shaped plug-in structure setting of the limiting guide rail 222, the first slide groove 239, and the second slide groove 244, on the one hand, the installation of the first embedded part 230 and the second embedded part 240 can be guided, and on the other hand, the first embedded part 230 and the second embedded part 240 can be limited axially on the fixing frame 220, thereby improving the installation position accuracy of the first frame and the second frame on the fixing frame 220.

[0119] In a preferred embodiment, Figure 1 , Figure 2 , Figure 5 As shown, a plurality of docking ears 224 are fixedly provided on the fixing frame 220 , the first cover portion 250 is bolted to the docking ears 224 at corresponding positions on the fixing frame 220 via the first connecting ears 254 , and the second cover portion 260 is bolted to the docking ears 224 at corresponding positions on the fixing frame 220 via the second connecting frame 264 .

[0120] In a preferred embodiment, Figure 1 , Figure 2 , Figure 5 As shown, an avoidance groove 221 is formed on the inner wall of the accommodating cavity 223 at a position corresponding to the interval between the first lens frame and the second lens frame.

[0121] The switching slot 210 is specifically configured as a gap between the first mirror frame and the second mirror frame and an avoidance slot 221 .

[0122] It can be understood that the avoidance groove 221 can avoid the rotating frame 320 when the switching bracket 300 rotates to switch the film 400.
