[0029] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0030] Reference Figures 1 to 5The embodiment of the utility model provides a device for fixing a car ceiling light, comprising a housing 10 and a locking mechanism 30. Optionally, the housing can be fixed to the car ceiling by threaded connection, or fixed to the car ceiling by curing adhesive. The housing 10 is in a cubic shape, and the inner cavity of the housing 10 is provided with a ceiling light mounting seat 20, and the lower end face of the ceiling light mounting seat 20 is square. Specifically, the ceiling light mounting seat 20 is connected to the inner top wall of the housing 10 through a first support column 15. The lower end face of the housing 10 is provided with a square through hole 11 aligned with the ceiling light mounting seat 20, and a card block 21 is provided on both sides adjacent to the lower end face of the ceiling light mounting seat 20, and the cross section of the card block 21 is L-shaped, and forms a first card slot 22 with the lower end face of the ceiling light mounting seat 20, and the width of the first card slot 22 is equal to the thickness of the lamp panel of the car ceiling light. It should be noted that the blocks 21 located on the two adjacent sides of the lower end surface of the ceiling light mounting seat 20 can be connected or separated. In this embodiment, the blocks 21 are connected. The locking mechanism 30 is arranged in the inner cavity of the housing 10, and includes a first driven shaft 31 and a second driven shaft 32 perpendicular to each other. The first driven shaft 31 and the second driven shaft 32 are respectively perpendicular to the two sides of the ceiling light mounting seat 20 away from the block 21. The first driven shaft 31 is sleeved with a first movable block 33, and the second driven shaft 32 is sleeved with a second movable block 34. The sides of the first movable block 33 and the second movable block 34 close to the ceiling light mounting seat 20 are parallel to the sides of the ceiling light mounting seat 20. The first movable block 33 can approach or move away from the ceiling light mounting seat 20 under the rotation of the first driven shaft 31, and the second movable block 34 can approach or move away from the ceiling light mounting seat 20 under the rotation of the second driven shaft 32.

[0031] The locking mechanism 30 further includes a driving shaft 35 with one end exposed outside the housing 10, and the other end of the driving shaft 35 is connected to a first bevel gear. Optionally, the driving shaft 35 is integrally formed with the first bevel gear. One end of the first driven shaft 31 and the second driven shaft 32 are both meshed and connected with the first bevel gear. Specifically, one end of the first driven shaft 31 is meshed with the first bevel gear through a second bevel gear (not shown), and one end of the second driven shaft 32 is meshed with the first bevel gear through a third bevel gear (not shown), and the second bevel gear and the third bevel gear do not interfere with each other. The angle between the first driven shaft 31 and the driving shaft 35, and the angle between the second driven shaft 32 and the driving shaft 35 are both 135 degrees. When the driving shaft 35 rotates, the first driven shaft 31 and the second driven shaft 32 rotate synchronously under the rotation of the first bevel gear. A knob 39 is provided at one end of the active shaft 35 exposed outside the housing 10. By manually rotating the knob 39, the active shaft 35 can be rotated, thereby driving the synchronous rotation of the first driven shaft 31 and the second driven shaft 32. Optionally, a snap ring 351 is provided on the active shaft 35, and the distance from the snap ring 351 to the knob 39 is equal to the thickness of the side wall of the housing 10. The active shaft 35 passes through the side wall of the housing 10, and the side wall of the housing 10 is located between the snap ring 351 and the knob 39, so as to prevent the active shaft 35 from moving relative to the side wall of the housing 10.

[0032] The vehicle ceiling light fixing device further comprises a knob limiting cap 40, and the knob limiting cap 40 is detachably connected to the housing 10. When the ceiling light is installed, the knob limiting cap 40 prevents the knob 39 from rotating.

[0033] The first limiting ring 14 is provided on two adjacent inner side walls of the housing 10, and one end of the first driven shaft 31 and the second driven shaft 32 is sleeved in the first limiting ring 14. As described above, the other ends of the first driven shaft 31 and the second driven shaft 32 are meshed and connected to the first bevel gear. Although both ends of the first driven shaft 31 and the second driven shaft 32 have support points, which can play a supporting and limiting role, the supporting effect of the first bevel gear on the first driven shaft 31 and the second driven shaft 32 is not stable. Therefore, the inner top wall of the housing 10 is also provided with a plurality of second support columns 16, and the second support columns 16 are provided with second limiting rings 17. The ends of the first driven shaft 31 and the second driven shaft 32 close to the first bevel gear respectively pass through different second limiting rings 17 to increase the stability of the first driven shaft 31 and the second driven shaft. Similarly, the side wall of the housing 10 supports one end of the driving shaft 35 , and the end close to the first bevel gear also passes through the second limiting ring 17 to increase the stability of the driving shaft 35 .

[0034] The first driven shaft 31 and the second driven shaft 32 are both provided with external threads, and the first movable block 33 and the second movable block 34 are both provided with internal threaded holes corresponding to the external threads. It should be noted that when the first driven shaft 31 and the second driven shaft 32 rotate synchronously, the first movable block 33 and the second movable block 34 can synchronously move away from or approach the ceiling light mounting seat 20. The first movable block 33 and the second movable block 34 are both provided with a second card slot 36 on one side close to the ceiling light mounting seat 20, and the width of the second card slot 36 is equal to the sum of the thickness of the ceiling light mounting seat 20 and the thickness of the lamp panel of the ceiling light, so that when the second card slot 36 is close to the ceiling light mounting seat 20, the ceiling light mounting seat 20 and the lamp panel of the ceiling light can be inserted into the second card slot 36.

[0035] The upper end surfaces of the first movable block 33 and the second movable block 34 are both provided with an upper limit rod 37, and the lower end surfaces of the first movable block 33 and the second movable block 34 are both provided with a lower limit rod 38. The inner top wall of the housing 10 is provided with an upper limit groove 12 corresponding to the upper limit rod 37, and the inner bottom wall of the housing 10 is provided with a lower limit groove 13 corresponding to the lower limit rod 38. When the first movable block 33 and the second movable block 34 are close to or away from the ceiling lamp mounting seat 20, the upper limit groove 12 and the lower limit groove 13 limit the first movable block 33 and the second movable block 34 to prevent them from rotating.

[0036] It should be noted that the roof light includes a light board, a lamp holder mounted on the light board, and a lighting lamp mounted on the lamp holder. The cross section of the light board is square, and the size is the same as the size of the lower end surface of the ceiling light mounting base 20. After the roof light is installed, the upper end surface of the light board is attached to the lower end surface of the ceiling light mounting base 20.

[0037] The utility model discloses a car ceiling light fixing device, and the specific implementation method is as follows: when installing the ceiling light, the lamp panel of the ceiling light is fitted on the ceiling light mounting seat 20 through the through hole 11 of the lower end surface of the shell 10, and the adjacent two sides of the lamp panel of the ceiling light are inserted into the first slot 22; by manually rotating the knob 39, the rotation of the active shaft 35 can be realized, thereby driving the rotation of the first driven shaft 31 and the second driven shaft 32, so that the first movable block 33 and the second movable block 34 are close to the ceiling light mounting seat 20 at the same time and contact the lamp panel of the ceiling light, and the lamp panel of the ceiling light is generated with a force pointing to the direction of the first slot 22 to clamp and fix the ceiling light. When disassembling the ceiling light, the knob 39 is manually rotated again to drive the rotation of the active shaft 35, thereby driving the rotation of the first driven shaft 31 and the second driven shaft 32, so that the first movable block 33 and the second movable block 34 are away from the ceiling light mounting seat 20 at the same time. At this time, the lamp panel of the car roof light changes from a clamped state to a loose state, and the car roof light can be removed from the fixing device. Compared with the traditional fixing method of connecting the car roof light by bolts, the car roof light fixing device provided by the utility model drives the rotation of the active shaft 35 by manually rotating the knob 39, thereby driving the rotation of the first driven shaft 31 and the second driven shaft 32, so that the first movable block 33 and the second movable block 34 are close to or away from the ceiling light mounting seat 20, thereby clamping or loosening the lamp panel of the car roof light, and realizing the installation and removal of the car roof light. The installation and removal method is simple to operate and efficient, which is conducive to the maintenance or replacement of the lamp of the car roof light.

[0038] As described above, the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
