Embodiment

[0028] The application is further described below in conjunction with the drawings and specific embodiments.

[0029] Embodiment, refer to the drawings Figures 1-11The application discloses a top lamp assembly of an integrated fragrance system, which is applied to a vehicle or other transportation tool and comprises a top lamp body 100, a function button module, a control circuit board 200 and a fragrance box 300 with an air outlet hole 301. The top lamp body 100 is provided with an air passage 130 communicated with the air outlet hole 301, the air passage 130 is provided with an air inlet 131 and an air outlet 132, and a blower 600 is arranged in the air passage 130; the control circuit board 200 is connected with the blower 600 and can control the rotation of the blower 600 so as to drive the airflow in the air passage 130 to flow. The function button module comprises one or more of commonly used switches, buttons, touch buttons, indicator lights and state lights on the top lamp of the vehicle, and is not shown in the drawings of the embodiment. The top lamp body 100 is provided with a driving device 400 and a fragrance control mechanism 500, the fragrance control mechanism 500 comprises an air outlet valve 510 arranged in the air passage 130 and used for opening or closing the air outlet hole 301 of the fragrance box, The driving device 400 is connected with the control circuit board 200, and when the driving device 400 works, the air outlet valve 510 can be driven to move to an open position state so that the air outlet hole 301 of the fragrance box is communicated with the air passage 130 or the air outlet valve 510 can be driven to move to a closed position state.

[0030] Compared with the existing vehicle-mounted fragrance system, the top lamp assembly of the embodiment integrates the fragrance system, the space originally occupied by the fragrance system can be saved, part of electronic components can be integrated together so as to reduce the number of electronic components, meanwhile, the software control part can also be integrated together and controlled by a single MCU, the top lamp, the button and the fragrance system are simultaneously controlled, and the cost is reduced as a whole; in addition, the fragrance function of the top lamp assembly of the embodiment can be turned on or turned off according to the needs of a user.

[0031] The single fragrance odor is likely to be boring for the user after a long time of use. If the fragrance is replaced before it is used up, it is a waste and the user may want to use it again after a while. If the fragrance is not replaced, the user cannot relieve the boredom. To solve this problem and increase the diversity of the fragrance odor in the car, the number of fragrance boxes 300 is increased to two and the fragrance switching function is added in this embodiment. Specifically, the fragrance control mechanism 500 includes two fragrance outlet valves 510, a transmission member 520, and a reset member 530. The fragrance outlet valve 510 includes a closed part 511, a rotating part 512, and a contact part 513. When the default fragrance system is not turned on, the closed part 511 of the fragrance outlet valve covers and closes the fragrance outlet hole 301 of the fragrance box. When the contact part 513 is moved downward by an external force, the fragrance outlet valve 510 rotates about the rotating part 512. At this time, the closed part 511 moves upward to make the fragrance outlet hole 301 of the fragrance box communicate with the air channel 130. The transmission member 520 includes a fixed part 521 and a driving part 522. The fixed part 521 is fixedly connected with the driving device 400. The driving part 522 is used to contact and move the fragrance outlet valve 510. The driving device 400 can move the transmission member 520 when it works. After the transmission member 520 moves, the driving part 522 can contact and move one of the fragrance outlet valves 510 to the open position state to make the fragrance outlet hole 301 of the corresponding fragrance box communicate with the air channel 130. The reset member 530 contacts and exerts pressure on the transmission member 520 or the fragrance outlet valve 510 to make the fragrance outlet valve 510 move to the closed position state.

[0032] The structure of the fragrance control mechanism 500 is various, and according to the different structure of the fragrance control mechanism 500, the type of the driving device 400 driving the fragrance control mechanism 500 can also change, and the driving device 400 can adopt a motor, a linear motor, a solenoid valve, etc. In the preferred scheme of the embodiment, the driving device 400 includes a fragrance cutting motor 410, and the transmission member 520 is a rotating switching member 5201. The fragrance cutting motor 410 can drive the rotating switching member 5201 to rotate forward or reverse when it works. The driving part 522 of the rotating switching member 5201 can contact and drive one fragrance valve 510 to move to the open position state after the rotating switching member 5201 rotates forward or reverse. Specifically, the rotating switching member 5201 includes a fixed part 521, a first driving part 5221 and a second driving part 5222. The two driving parts 522 are symmetrically arranged left and right, and are located above the contact part 513 of the two fragrance valves 510 when the default fragrance system is not turned on. When the rotating switching member 5201 rotates forward, the first driving part 5221 thereof contacts and drives the corresponding first fragrance valve 510 to move, and the second driving part 5222 does not contact the second fragrance valve 510. Similarly, when the rotating switching member 5201 rotates reverse, the second driving part 5222 thereof contacts and drives the corresponding second fragrance valve 510 to move, and the first driving part 5221 does not contact the first fragrance valve 510.

[0033] In another embodiment, the structure of the rotating switching member 5201 can only include one driving part, which is located between the contact parts 513 of the two fragrance valves 510 when the default fragrance system is not turned on. After the rotating switching member 5201 rotates forward or reverse, the driving part 522 thereof can contact and drive the left or right fragrance valve 510 to move to the open position state.

[0034] When the ceiling lamp assembly has multiple fragrance boxes and fragrance switching mechanisms, the overall internal structure of the ceiling lamp assembly will become complex. The design of the internal structure needs to consider not only how to facilitate the replacement of multiple fragrance boxes 300, but also the original function of the ceiling lamp assembly should not be affected. In order to solve this problem, the ceiling lamp main body 100 in the embodiment includes a fixed main body 110 and a function panel 120. The function panel 120 can be flipped open relative to the fixed main body 110. The inner side of the function panel 120 is detachably provided with the fragrance box 300, and the outer side of the function panel 120 is provided with a function key module.

[0035] The function panel 120 of the ceiling lamp assembly can be flipped open to facilitate replacement of the fragrance box 300. However, the function panel 120 often needs to be integrated with various buttons or switches, which imposes certain requirements on the internal electronic circuit layout of the ceiling lamp assembly. In the embodiment, the control circuit board 200 includes a first circuit board 210 and a second circuit board 220 connected by a flexible flat cable. The first circuit board 210 is usually a necessary main circuit board, which is arranged in the function panel 120 and connected with a function button module mounted on the function panel 120, because the function panel 120 is integrated with a plurality of buttons, indicator lights and switches. The second circuit board 220 is a secondary circuit board, which is arranged in the fixed main body 110 and connected with the driving device 400 on the fixed main body 110. The second circuit board 220 can provide support for various expansion functions of the ceiling lamp assembly, such as a driving record camera or a driver driving state camera.

[0036] The function panel 120 can be flipped open in various structures, such as a manual pure mechanical structure, an electronic full-automatic structure or an electronic semi-automatic structure. In order to ensure the overall appearance and aesthetics of the ceiling lamp assembly and the operability of the buttons and switches after the function panel 120 is flipped, the electronic semi-automatic structure is preferably adopted in the embodiment. Specifically, the fixed main body 110 is provided with a panel locking mechanism 700, and the inner side surface of the function panel 120 is provided with a locking portion 121 matched with the panel locking mechanism 700. The driving device 400 further includes an electromagnetic valve 420, which can drive the panel locking mechanism 700 to switch between a locking position state and an unlocking position state. When the function panel 120 is in a closed state, the panel locking mechanism 700 is in the locking position state and can be connected with the locking portion 121 to prevent the locking portion 121 from being separated.

[0037] The panel locking mechanism 700 has various structures. In the preferred scheme of the embodiment, there are two sets of panel locking mechanisms 700 arranged on the left and right sides inside the ceiling lamp assembly, which can better fix the function panel 120. The panel locking mechanism 700 includes a straight rod 710, a rotating rod 720 and a latch 730 connected in sequence. The electromagnetic valve 420 can drive the straight rod 710 to move linearly. The straight rod 710 moves while driving the rotating rod 720 to rotate through a sliding slot and sliding shaft cooperation. The rotating rod 720 moves while driving the latch 730 to move linearly through the sliding slot and sliding shaft cooperation. When the electromagnetic valve 420 is started, the panel locking mechanism 700 is driven to move, so that the latch 730 is retracted. At this time, the latch 730 is no longer in contact with the locking portion 121 on the function panel 120, so that the function panel 120 can be flipped open. After the electromagnetic valve 420 is closed, it is automatically reset to drive the panel locking mechanism 700 to reset, so that the latch 730 is extended forward. When the function panel 120 is closed, the locking portion 121 can be locked with the latch 730 to prevent the function panel 120 from being flipped.

[0038] Although the functional panel 120 can be relatively fixed to the main body 110 and opened, how to make the functional panel 120 more safely open is also a problem to be considered. In the embodiment, a damping member is also arranged in the fixed main body 110, which is connected with the functional panel 120 and slows down the opening speed when the functional panel 120 is opened. Specifically, the damping member is a tooth damper 800, and the functional panel 120 also has a gear part 122 near the rotating shaft and connected with the tooth damper 800. When the functional panel 120 is unlocked and opened, the functional panel 120 is slowly opened under the damping action of the tooth damper 800, and when it needs to be closed, the functional panel 120 is manually closed. Slow opening and closing can reduce the impact force when the functional panel 120 is opened and closed, and avoid violent damage.

[0039] In order to prevent the user from mistakenly touching the key switch of the functional panel 120 after the functional panel 120 is turned over, the top light assembly also includes a panel detection switch 900 connected with the control circuit board 200, which is used to detect and determine the current position state of the functional panel 120. When it is detected that the functional panel 120 is in an open state, the control circuit board 200 ignores the control signal sent by the key switch module. The panel detection switch 900 can be a pressure sensor, a distance sensor or a circuit on-off micro switch, etc. In the embodiment, a circuit on-off micro switch with lower cost is preferably adopted. Its principle is that when the functional panel 120 is opened, the moving contact and the static contact of the circuit on-off micro switch are separated and the circuit is disconnected, and the control circuit board 200 determines that the functional panel 120 has been opened. When the functional panel 120 is closed, the functional panel 120 contacts the moving contact of the circuit on-off micro switch and makes the moving contact and the static contact contact and the circuit is closed, and the control circuit board 200 determines that the functional panel 120 has been closed.

[0040] Considering that the light may not be good if the user replaces the fragrance box 300 at night, the inner side surface of the functional panel 120 also has an LED lamp module connected with the control circuit board 200. When it is detected that the functional panel 120 is in an open state, the control circuit board 200 controls the LED lamp module to light up.

[0041] In addition to the fragrance switching function and the function panel flipping function mentioned above, the structure design of the air passage of the top lamp assembly also needs to be considered. From the perspective of structure design, if a one-way straight air passage structure design is adopted, the airflow in the air passage will be hindered due to the presence of the two fragrance outlet valves 510, and the layout of the air duct structure inside the top lamp assembly is not good. Therefore, in this embodiment, the air passage 130 includes an air inlet passage 1301, a first sub-passage 1302, and a second sub-passage 1303. The air blower 600 is arranged in the air inlet passage 1301. The first sub-passage 1302 and the second sub-passage 1303 respectively communicate with the fragrance outlet holes 301 of one fragrance box. The two fragrance outlet valves 510 are respectively located in the first sub-passage 1302 and the second sub-passage 1303. The fragrance outlet valve 510 can close the fragrance outlet hole 301 of the fragrance box while closing the air passage 130 where it is located.

[0042] According to different air outlet modes, the fragrance top lamp assembly can be divided into independent air outlet type and non-independent air outlet type. The independent air outlet type is a top lamp assembly with fragrance function, which does not need to cooperate with other parts in the vehicle to emit fragrance. The non-independent air outlet type is a top lamp assembly that needs to be connected to the air duct inside the vehicle and needs to cooperate with other parts in the vehicle to emit fragrance. This embodiment adopts the independent air outlet type. Specifically, the air outlet 132 of the air passage 130 is located at the bottom of the outer side of the top lamp main body 100 facing the inside of the vehicle. The first sub-passage 1302 has a first air outlet 1321, and the second sub-passage 1303 has a second air outlet 1322. The first air outlet 1321 and the second air outlet 1322 are in communication with the air holes 111 on the shell of the top lamp main body 100. This arrangement allows the fragrance emitted by the fragrance box 300 to directly enter the vehicle interior. Since the top lamp assembly is located above the middle of the left and right driver seats, the fragrance is closer to the driver, and the driver can quickly smell the fragrance.

[0043] In addition, the top lamp main body 100 is also provided with a detachable and washable filter screen 1000, which is arranged at and covers the air outlet 132 of the air passage 130. The filter screen 1000 can filter dirt and dust in the air flow with fragrance.

[0044] In another embodiment, the air outlet 132 of the air passage 130 can be located at the inner side of the top lamp main body 100 facing the ceiling. The first sub-passage 1302 and the second sub-passage 1303 share one air outlet 132, which can be connected with the air inlet of the air duct in the ceiling. This arrangement allows the fragrance to enter the air duct inside the vehicle, and the fragrance can be emitted from the air outlet of the air duct at other positions in the vehicle according to the design requirements of the manufacturer.

[0045] While the application has been described by reference to the preferred embodiments, it should be understood that various changes can be made and equivalents can be substituted for elements thereof without departing from the scope of the application. In addition, many modifications can be made to adapt a particular situation or material to the teachings of the application without departing from the central scope thereof. Therefore, it is intended that the application not be limited to the particular embodiments disclosed as the best mode contemplated for carrying out this application, but that the application will include all embodiments falling within
