As shown in fig. 1, the automotive interior dome lamp provided by the embodiment of the present application includes an illumination mechanism 1, an adjustment mechanism 2, and a dome lamp body 3.

The illumination means 1 is used to provide illumination light.

The adjusting mechanism 2 is connected to the illuminating mechanism 1, and the adjusting mechanism 2 is configured to adjust a position of the first end of the illuminating mechanism 1 in the first opening 31 to change an exit angle of the illuminating light in the first opening 31.

To sum up, the automobile indoor ceiling lamp provided by the embodiment of the application comprises a ceiling lamp body 3, an illuminating mechanism 1 and an adjusting mechanism 2, wherein the illuminating mechanism 1 can be assembled on the ceiling lamp body 3 and emits illuminating light through a first opening 31 on the ceiling lamp body 3 to illuminate the automobile indoor; the adjusting mechanism 2 can adjust the position of the lighting mechanism 1 in the first opening 31, so that the requirement of adjusting the position of the lighting mechanism 1 and the requirement of adjusting the lighting angle of the overhead lamp are met while the optical performance of the lighting mechanism 1 is guaranteed to be unchanged. Compare in correlation technique, the indoor dome lamp of car of this application embodiment has better adaptability.

For the sake of convenience of description, the structure and function of the automotive room dome lamp provided by the embodiment of the present application will be described in more detail and specifically with reference to fig. 1 to 12.

The illumination means 1 is used to provide illumination light. The lighting mechanism 1 can be connected with the switching device, and the circuit is switched on or off under the control of the switching device, for example, when the switching device is switched on, the circuit is switched on to generate current, and the lighting mechanism 1 can emit light to illuminate a part of the area in the vehicle cabin; when the switching device is turned off, the circuit is cut off and the lighting mechanism 1 stops emitting light.

The dome lamp body 3 can be fixed on the vehicle body, and then the lighting mechanism 1 and the adjusting mechanism 2 can be connected with the vehicle body through the dome lamp body 3. The dome lamp body 3 has a first opening 31, and a first end of the illumination mechanism 1 is located in the first opening 31, and the first end is an exit end of the illumination light. When viewed from a direction opposite to the first opening 31, the first end of the illumination mechanism 1 is exposed from the first opening 31, so that the illumination light is suitable for exiting from the first opening 31 into the vehicle interior. It should be noted that, based on the structure of the illumination mechanism, the emission directions of the illumination light rays emitted from the first end of the illumination mechanism are the same, and the structure of the illumination mechanism will be described in detail below.

The adjusting mechanism 2 is connected to the illuminating mechanism 1, and the adjusting mechanism 2 is configured to adjust a position of the first end of the illuminating mechanism 1 in the first opening 31 to change an exit angle of the illuminating light in the first opening 31. Illustratively, as shown in fig. 2(B), when the first end of the illumination mechanism 1 is located at the midpoint position (position B) of the first opening 31, the illumination light coincides with the axis of the first opening 31, that is, the illumination light exits in the direction perpendicular to the plane of the first opening 31, and the exit angle of the illumination light is 0 °. When the adjusting mechanism 2 adjusts the first end of the illuminating mechanism 1 to the position a shown in fig. 2(a), the angle formed by the illuminating light and the axis of the first opening 31 is 10 °, and the outgoing angle of the illuminating light is 10 °. When the adjusting mechanism 2 adjusts the first end of the illumination mechanism 1 to the position C shown in fig. 2(C), the angle formed by the illumination light and the axis of the first opening 31 is-10 °, and the outgoing angle of the illumination light is-10 °. Where the position a and the position C are two positions symmetrical with respect to the axis of the first opening 31.

As shown in fig. 3, in some implementations of the embodiment of the present application, the adjusting mechanism 2 includes a first bevel gear 21 and a second bevel gear 22 engaged with each other, the first bevel gear 21 is connected to the dome lamp body 3, the second bevel gear 22 is connected to the illumination mechanism 1, and the second bevel gear 22 is configured to rotate the illumination mechanism 1 under the driving of the first bevel gear 21.

The axis of the first bevel gear 21 and the axis of the second bevel gear 22 are perpendicular to each other, and the teeth of both gears mesh with each other. The first bevel gear 21 may be a driving gear, the second bevel gear 22 may be a driven gear, and when the first bevel gear 21 rotates, the second bevel gear 22 engaged with the first bevel gear 21 also rotates along with the first bevel gear and drives the illumination mechanism 1 fixedly connected to the second bevel gear 22 to rotate together, so that the position of the first end of the illumination mechanism 1 in the first opening 31 changes, and the emergent angle of the illumination light also changes along with the first end.

As shown in fig. 4, in the embodiment of the present application, the first bevel gear 21 may be a bevel gear shaft, and include a gear body 211 and a shaft body 212. The gear body 211 is sleeved on one end of the shaft body 212 and is fixedly connected with the shaft body 212. The axis of the gear body 211 coincides with the axis of the shaft body 212, and the two rotate synchronously. Meanwhile, the top of the shaft body 212 (i.e., the end on which the gear body 211 is sleeved) may be further provided with a special-shaped groove 213, and the special-shaped groove 213 may be, for example, a cross-shaped groove, so that the wedge-shaped head of the cross screwdriver 4 may be inserted into the cross-shaped groove (as shown in fig. 12) to drive the first bevel gear 21 to rotate. Of course, other manners of driving the first bevel gear shaft to rotate may also be adopted in the embodiment of the present application, for example, the top of the shaft body 212 is configured to be a special-shaped structure, and then a tool is engaged with the top to rotate, or a driving device such as a motor is connected to the first bevel gear.

Continuing to refer to fig. 3, the adjusting mechanism 2 further includes a fixed limiting plate 23, the fixed limiting plate 23 is used for fixing the first bevel gear 21 on the dome lamp body 3, wherein a first fixing hole is formed in the fixed limiting plate 23, and the size of the first fixing hole is matched with the diameter of the shaft body 212 of the first bevel gear 21, so that the shaft body 212 of the first bevel gear 21 can be located in the first fixing hole, and one end of the shaft body 212, which is far away from the gear body 211, is in contact with the dome lamp body 3.

After the shaft body 212 of the first bevel gear 21 is inserted into the first fixing hole of the fixing limit plate 23, the first fixing hole limits the first bevel gear 21, so that the first bevel gear 21 cannot fall down and break away from the first fixing hole. Meanwhile, the shaft body 212 of the first bevel gear 21 can also rotate in the first fixing hole by the driving force.

In order to further enhance the fixing firmness of the first bevel gear 21, in some embodiments of the present application, a limiting baffle 24 may be further connected to the fixing limiting plate 23, the limiting baffle 24 has a second fixing hole corresponding to the first fixing hole, and the shaft body 212 of the first bevel gear 21 is adapted to pass through the first fixing hole and the second fixing hole. Because the contact area between the superposed limit baffle 24 and the shaft body 212 is increased, the first bevel gear 21 can be better limited, and the first bevel gear 21 is prevented from toppling over. Wherein, the limit baffle 24 can also be an integrated structure with the fixed limit plate 23, that is, the fixed limit plate 23 can be one of a convex structure, a step structure or a circular truncated cone structure.

In order to save materials and reduce cost, as shown in fig. 3, in other embodiments of the present application, the fixing position-limiting plate 23 may be a plate structure with a middle portion protruding upwards and higher than two ends, so that the first fixing hole may contact with a position as high as possible on the shaft body 212, thereby preventing the first bevel gear 21 from falling. Meanwhile, the two ends of the fixed limiting plate 23 are lower in height, so that the function of avoiding the second bevel gear 22 can be achieved.

As shown in fig. 5, in some implementations of the embodiments of the present application, the dome lamp body 3 has two fixing posts 32 and one limiting boss 33, the limiting boss 33 is located between the two fixing posts 32, and the axial length of the limiting boss 33 is smaller than that of the fixing posts 32.

As shown in fig. 3, two fixing posts 32 are respectively connected to two ends of the fixing limit plate 23, and are used for fixing the fixing limit plate 23 on the dome lamp body 3. For example, screw holes may be formed at the tops of the two fixing posts 32, and mounting holes corresponding to the screw holes may be formed in the fixing limit plate 23, and screws may be inserted through the mounting holes and screwed into the screw holes, thereby fixing the fixing mounting plate to the two fixing posts 32.

The end of the shaft body 212 of the first bevel gear 21, which is far away from the gear body 211, can be abutted against the limit boss 33, so that abrasion to the dome lamp body 3 caused by rotation of the shaft body 212 of the first bevel gear 21 is avoided. In addition, the limiting boss 33 can also enhance the strength of the dome lamp body 3 which is in contact with the shaft body 212 of the first bevel gear 21, and the dome lamp body 3 is prevented from being damaged in the angle adjusting process.

In some embodiments of the present application, the roughness of the limiting boss 33 may be designed to be smaller than that of the dome lamp body 3, so that the friction force when the first bevel gear 21 rotates may be reduced.

As shown in fig. 1, in the embodiment of the present application, the illumination mechanism 1 may include a light source assembly 11 and a lens assembly 12. There may be a fixed connection between the light source assembly 11 and the lens assembly 12, and there is no relative movement between the two.

Light source subassembly 11 is the pointolite, and the pointolite can be fixed in the one end of lens subassembly 12 to send the illuminating light along a plurality of directions outgoing all around, and lens subassembly 12 can focus the illuminating light that the pointolite sent, and the light through the focus of lens subassembly 12 all is followed same direction outgoing.

The end of the lens assembly 12 away from the light source assembly 11 is located in the first opening 31, wherein the end of the lens assembly 12 away from the light source assembly 11 is the first end of the illumination mechanism 1, that is, the emergent end of the illumination light. The light emitted from the end of the lens assembly 12 away from the light source assembly 11 is focused illumination light, and all the illumination light is emitted along the same direction, so the light emitted from the first end of the illumination mechanism 1 is emitted along the same direction.

As shown in fig. 6, in the embodiment of the present application, the lens assembly 12 may include a base 121 and a lens body 122, the base 121 has an inner cavity, and the lens body 122 is located in the inner cavity of the base 121 and connected to the base 121.

Illustratively, the lens body 122 and the base 121 may be fixed by a snap-fit. As shown in fig. 7, a plurality of limiting ribs 1213 are disposed in the inner cavity of the base 121, and the plurality of limiting ribs 1213 are regularly arranged on the inner wall of the base 121 for limiting the position of the lens body 122 in the inner cavity of the base 121 and ensuring the focusing effect of the lens body 122.

As shown in fig. 7, in some embodiments, at least one error-proof rib 1214 is further disposed on the inner wall of the base 121, and the error-proof rib 1214 is used to prevent the lens body 122 from being installed incorrectly and losing the focusing function.

As shown in fig. 11, an error-proofing groove 1221 is provided on the lens body 122, the error-proofing groove 1221 corresponds to the error-proofing rib 1214 one by one, and after the lens body 122 is assembled into the inner cavity of the base 121, the error-proofing rib 1214 is located in the error-proofing groove 1221. When there are a plurality of error-proofing ribs 1214, the plurality of error-proofing ribs 1214 are irregularly arranged to avoid losing the error-proofing effect.

In some embodiments of the present application, the size of the error-proofing groove 1221 may be slightly larger than the size of the corresponding error-proofing rib 1214, for example, after the lens body 122 is assembled, the error-proofing groove 1221 and the corresponding error-proofing rib 1214 may have a margin of 0.2mm therebetween, which may not affect the fixing effect of the lens body 122, but also reduce the assembling difficulty of the lens body 122, and improve the assembling efficiency.

As shown in fig. 1, the base 121 is also connected to the dome lamp body 3, and the base 121 is rotatable with respect to the dome lamp body 3, and when the adjustment mechanism 2 adjusts the position of the illumination mechanism 1, the adjustment mechanism 2 actually changes the position by driving the base 121 to rotate with respect to the dome lamp body 3.

As shown in fig. 6 and 8, a second opening 1211 is formed on the base 121, the second opening 1211 is adapted to correspond to the first opening 31 and the size of the second opening 1211 is smaller than the size of the first opening 31. One end of the lens body 122 is connected to the light source assembly 11, and the other end is located in the second opening 1211.

When the exit angle of the illumination light is 0 °, the axis of the first opening 31 coincides with the axis of the second opening 1211, the included angle formed by the two axes is also 0 °, and the orthographic projection area of the second opening 1211 on the plane parallel to the first opening 31 is the largest and is located inside the orthographic projection of the first opening 31 on the plane. After the adjusting structure adjusts the position of the illumination mechanism 1, the angle formed by the axis of the first opening 31 and the axis of the second opening 1211 changes, and the size of the orthographic projection of the second opening 1211 on the plane parallel to the first opening 31 is reduced, but still inside the orthographic projection of the first opening 31 on the plane. Therefore, the illumination light emitted from the second opening 1211 can pass through the first opening 31 without being blocked by the dome lamp body 3.

As shown in fig. 9, in some implementations of embodiments of the present application, an end surface 1212 of the base 121 proximate to the first opening 31 is a curved surface. If the end surface 1212 of the base 121 close to the first opening 31 is a plane, along with the rotation of the base 121 relative to the dome lamp body 3, the distance between the portion of the base 121 corresponding to the first opening 31 and the first opening 31 is small and large, which greatly affects the aesthetic measure of the dome lamp in the automobile room, and the rotation space required to be occupied during the rotation is larger. If the end surface 1212 of the base 121 close to the first opening 31 is an arc surface, when the base 121 rotates relative to the dome lamp body 3, the arc surface structure may also compensate for the appearance defect, so that the distance between the portion of the base 121 corresponding to the first opening 31 and the first opening 31 is kept constant, and the aesthetic measure is improved, and meanwhile, the rotation space occupied by the base 121 during the rotation is relatively small.

With continued reference to fig. 8 and 9, in the embodiment of the present application, the lens assembly 12 further includes a first rotating shaft 123 and a second rotating shaft 124, the first rotating shaft 123 and the second rotating shaft 124 are respectively connected to two opposite outer walls of the base 121, and an axis of the first rotating shaft 123 coincides with an axis of the second rotating shaft 124, so that the first rotating shaft 123, the base 121, and the second rotating shaft 124 can rotate synchronously. The first rotating shaft 123, the second rotating shaft 124 and the base 121 may be formed as separate bodies and then assembled together, or may be formed integrally and combined together.

As shown in fig. 5, in some implementations of the embodiments of the present application, the dome lamp body 3 has a receiving frame 34, and the receiving frame 34 can receive the base 121 and the lens assembly 12 and the light source assembly 11 located in the base 121.

Two opposite rotating shaft clamping grooves 341 are formed in two opposite frames of the accommodating frame 34, the first rotating shaft 123 and the second rotating shaft 124 can be respectively located in the two opposite rotating shaft clamping grooves 341, and the base 121 is clamped with the accommodating frame 34 of the dome lamp body 3 through the first rotating shaft 123 and the second rotating shaft 124. The first rotating shaft 123 and the second rotating shaft 124 can both rotate freely in the rotating shaft slot 341.

Continuing to refer to fig. 8, the first rotating shaft 123 and the second rotating shaft 124 are respectively provided with a limiting block, and the distance between the two limiting blocks is equal to the distance between the two opposite outer walls of the frames where the two opposite rotating shaft clamping grooves 341 are located, so that the lens assembly 12 can be effectively prevented from falling off the dome lamp body 3.

The second bevel gear 22 may be connected to the first shaft 123 for rotating the base 121. As shown in FIG. 10, in some embodiments, the second bevel gear 22 may also be a bevel gear shaft, the shaft of the second bevel gear 22 may have a key slot 221 thereon, and the first shaft 123 may have a key 1231 thereon, wherein the key slot 221 and the key 1231 cooperate to fixedly connect the second bevel gear 22 and the first shaft 123. In other embodiments, the second bevel gear 22 may also be directly sleeved on the first rotating shaft 123 and fixedly connected to the first rotating shaft 123 by gluing or welding, so that the two can rotate synchronously.

As shown in fig. 11, in the embodiment of the present disclosure, the light source assembly 11 may include an LED PCB (Printed Circuit Board) 111, and the LED PCB 111 is connected to the lens body 122 by means of hot-rivet welding. There are at least three welding points on the lens body 122, and the at least three welding points are not located on the same straight line.

Exemplarily, as shown in fig. 11, the LED PCB 111 may be a rectangular lamp panel, the LED lamp bead 1111 is disposed at the center of the rectangular lamp panel, four connection holes may be formed at four corners of the LED PCB 111, four connection posts 112 are disposed in the four connection holes, and the four connection posts 112 are connected to the lens body 122 by hot rivet welding, so that four welding points are formed on the lens body 122. Meanwhile, since the four solder joints on the lens body 122 are not in the same straight line, the connection between the LED PCB 111 and the lens body 122 is stable.

To sum up, the regulation principle of the indoor dome lamp of car that this application embodiment provided does:

The second bevel gear 22 is fixedly connected to the first rotating shaft 123, and the first rotating shaft 123 is fixedly connected to the base 121, so that when the second bevel gear 22 rotates, the first rotating shaft 123 and the base 121 rotate synchronously, while the dome lamp body 3 remains stationary. The light emitted from the light source assembly 11 is focused by the lens body 122 and then emitted from the second opening 1211 of the base 121, and after the base 121 rotates, the relative positions of the second opening 1211 and the first opening 31 of the dome lamp body 3 change, so that the emitting angle of the illumination light in the first opening 31 also changes.

Therefore, the indoor dome lamp of car that this application embodiment provided can utilize the cooperation between two bevel gears and the pivot, adjusts the position of lighting mechanism in first opening, and then changes the exit angle of light in first opening.
