[0004] However, the angle of the car interior ceiling light in the patented device is difficult to adjust, resulting in a relatively fixed lighting area, which makes it difficult for the device to adapt to the different usage needs of staff. Utility Model Content

[0005] The purpose of the utility model is to provide a multi-directional angle-adjustable interior ceiling light structure for a car.

[0006] The technical problem solved by the present invention is that in the existing equipment, since the angle of the car interior ceiling light is difficult to adjust, the lighting area thereof is relatively fixed, thereby making it difficult for the equipment to adapt to the different usage requirements of the staff.

[0007] The utility model can be implemented by the following technical solutions: a multi-directional angle-adjustable interior dome light structure for an automobile, comprising a dome light housing, a dome light inner housing adapted for rotationally connecting to a ball socket of the dome light housing, a first fulcrum for rotating the dome light inner housing in an X direction fixedly mounted in the ball socket of the dome light housing, two second fulcrums for rotating the dome light inner housing in a Y direction fixedly mounted in the ball socket of the dome light housing, a circuit board assembly being disposed in an inner cavity of the dome light inner housing, the circuit board assembly comprising a circuit board and an LED lamp;

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In the present invention, when the inner shell of the dome light needs to be rotated in the X direction, the inner shell of the dome light is rotated in the X direction to complete the rotation adjustment of the X direction of the car interior dome light. When the inner shell of the dome light needs to be rotated in the Y direction, the inner shell of the dome light is rotated in the Y direction to complete the rotation adjustment of the Y direction of the car interior dome light.

[0016] 2. The utility model rotates the threaded rod to make the push plate drive the blocking bead to move. The movement of the blocking bead causes the lubricant contained in the fixed box to be transported to the sponge plate through the connecting channel. After the sponge plate is filled with lubricant, the threaded rod is rotated in the opposite direction to reset the blocking bead. In the process of rotating the inner shell of the rotating ceiling light, the inner shell of the ceiling light abuts against the sponge plate so that the lubricant in the sponge plate can fully contact the outer peripheral wall of the inner shell of the ceiling light, thereby facilitating lubrication. Lubrication can reduce friction, thereby facilitating extending the service life of the ceiling light housing and the inner shell of the ceiling light. BRIEF DESCRIPTION OF THE DRAWINGS

The setting of the two second fulcrums 12 facilitates the stability of the dome light inner shell 2 when rotating in the Y direction.

[0031] The inner cavity of the dome light inner shell 2 is fixed with a rear cover 21 by bolts, and a lampshade 22 is provided at the front end of the rear cover 21. The lampshade 22 is made of polycarbonate, and has good light transmittance, heat resistance, impact resistance and weather resistance, and is suitable for different grades of vehicles; a accommodating area is formed between the rear cover 21 and the lampshade 22, and a circuit board assembly 23 is provided in the inner cavity of the accommodating area. The circuit board assembly 23 includes a circuit board and an LED lamp. A lamp holder is welded in the inner cavity of the accommodating area, and the LED lamp is connected to the circuit board through the lamp holder. A touch pad and a capacitive sensing chip electrically connected to the circuit board are provided on the circuit board. One end of the circuit board is connected to a connecting harness 24 for connecting to the power supply, and the circuit board is connected to the electrical system of the car through the connecting harness 24.

[0032] When the utility model is in use, when the inner shell 2 of the dome light needs to be rotated along the X direction, the inner shell 2 of the dome light is rotated in the X direction to complete the rotation adjustment of the X direction of the dome light in the car; when the inner shell 2 of the dome light needs to be rotated along the Y direction, the inner shell 2 of the dome light is rotated in the Y direction to complete the rotation adjustment of the Y direction of the dome light in the car. By adjusting the angle of the dome light in the car, the dome light in the car can be adaptively adjusted according to the use needs of the staff, thereby making the device more convenient to use.

[0033] Example 2

[0034] See also Figure 5-6As shown, the inner cavity of the ceiling light housing 1 is provided with a lubrication mechanism for assisting the rotation of the ceiling light inner shell 2. The lubrication mechanism includes two fixed boxes 3 symmetrically fixed in the ball socket of the auxiliary ceiling light inner shell 2. The inner cavity of the fixed box 3 contains a certain amount of lubricant. An arc-shaped PTFE plate 31 that matches the shape of the ceiling light inner shell 2 is fixedly installed on one side of the fixed box 3. A connecting channel 32 that is connected to the inner cavity of the fixed box 3 is opened through the inner cavity of the arc-shaped PTFE plate 31. A sponge plate 34 that abuts against the ceiling light inner shell 2 is horizontally slidably connected to the inner cavity of the connecting channel 32. The sponge plate Sliders 35 are fixedly installed on both sides of 34, and the inner cavity of the arc-shaped PTFE plate 31 is provided with a sliding groove 36 for the sliding of the slider 35. The inner cavity of the fixed box 3 is horizontally slidably connected with a push plate 37. The push plate 37 is fixedly installed with a blocking bead 33 for blocking the connecting channel 32 on one side close to the arc-shaped PTFE plate 31. The two sides of the ceiling light housing 1 are symmetrically threaded with a threaded rod 38. One end of the threaded rod 38 passes through the fixed box 3 and extends to the inner cavity of the fixed box 3. The end of the threaded rod 38 extending to the inner cavity of the fixed box 3 is rotatably connected to the push plate 37 through a bearing.

[0035] The bottom end of the fixed box 3 is fixedly connected to a feed pipe 39 for conveying lubricant. The provision of the feed pipe 39 facilitates regular delivery of lubricant to the inner cavity of the fixed box 3, thereby facilitating long-term use of the equipment.

[0036] When the present invention is in use, the threaded rod 38 is rotated to make the push plate 37 drive the blocking ball 33 to move, and the movement of the blocking ball 33 causes the lubricant contained in the fixed box 3 to be transported to the sponge plate 34 through the connecting channel 32. After the sponge plate 34 is filled with lubricant, the threaded rod 38 is rotated in the opposite direction to reset the blocking ball 33. In the process of rotating the inner shell 2 of the dome light, the lubricant in the sponge plate 34 can fully contact the outer peripheral wall of the inner shell 2 of the dome light through the contact between the inner shell 2 of the dome light and the sponge plate 34, thereby facilitating lubrication. Lubrication can reduce friction, thereby facilitating extending the service life of the entire equipment.
