The second end of the movable sleeve passes through the through hole and is connected to the reading lamp. The wire harness of the reading lamp is disposed inside the movable sleeve.

[0007] Further, a guiding channel is arranged along a preset path in the chamber. The part of the movable sleeve located in the chamber is constrained in the guiding channel, and the first end is guided to move in the guiding channel.

[0008] Further, the movable sleeve is made of a metal hose.

[0009] Further, the lamp base is disposed in the middle of the ceiling, and the guiding channel extends forward along the vehicle from the lamp base.

[0010] Further, the guiding channel includes a straight section arranged along the front-rear direction of the vehicle, and a transition section that is curved and connected between the straight section and the through hole.

[0011] Further, a fixed sleeve is fixedly arranged in the chamber, and the guiding channel is formed in the fixed sleeve.

[0012] Further, limiting structures are arranged at the ports at both ends of the fixed sleeve, and a limiting protrusion is arranged at the first end; the first end is restricted within the fixed sleeve by the blocking of the two limiting structures.

[0013] Further, the reading lamp includes a lamp body and a connecting portion arranged on the back of the lamp body; a receiving groove and a connecting and mating portion are arranged on the lamp base; as the reading lamp is installed in place, the lamp body is received in the receiving groove, and the connecting portion is connected to the connecting and mating portion.

[0014] Further, the connecting portion is configured as a stud structure with external threads on the circumferential surface, and the connecting and mating portion includes internal threads arranged on the inner wall of the through hole and matching the external threads; or, the connecting portion is configured as a chuck that can be clamped in the through hole, and the through hole constitutes the connecting and mating portion.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] For the reading lamp assembly of the present invention, by arranging a lamp base with a through hole on the ceiling, the reading lamp is detachably arranged on the lamp base, and the wire harness is threaded through the movable sleeve. Then, when the removed reading lamp is pulled, the movable sleeve can be partially pulled into the passenger compartment, facilitating the convenient movement and adjustment of the position of the reading lamp; when the reading lamp is held and moved back to the position of the lamp base, the movable sleeve can be pushed back into the chamber, and then the reading lamp can be installed on the lamp base, realizing the standardized installation and arrangement of the reading lamp, which is beneficial to improving the use convenience of the reading lamp in the vehicle.

[0017] In addition, a guiding channel is configured in the chamber to realize the constraint and guidance of the movable sleeve.

[0037] The present invention will be described in detail below with reference to the drawings and in combination with embodiments.

[0038] Embodiment 1

[0039] This embodiment relates to a reading lamp assembly, which can improve the convenience of use of the vehicle reading lamp 3; an exemplary structure thereof is as Figures 1 to 5 shown.

[0040] Generally speaking, the reading lamp assembly includes a lamp base 22 provided on the ceiling 1 of the vehicle, a reading lamp 3 detachably mounted on the lamp base 22, and a movable sleeve 42. Among them, a through hole 221 is provided on the lamp base 22, the first end 421 of the movable sleeve 42 is movably disposed in a chamber 20 between the ceiling 1 and the roof sheet metal 2, the second end 422 of the movable sleeve 42 passes through the through hole 221 and is connected to the reading lamp 3, and the wire harness 5 of the reading lamp 3 is disposed inside the movable sleeve 42.

[0041] Of course, as long as the first end 421 of the movable sleeve 42 is not fixed in the chamber 20, the movable sleeve 42 can enter the passenger compartment from the through hole 221 under the traction of the reading lamp 3, or be pushed back into the chamber 20. However, the use effect of randomly placing the movable sleeve 42 into the chamber 20 is poor. In this embodiment, a guiding channel arranged along a preset path is configured in the chamber 20, and the part of the movable sleeve 42 located in the chamber 20 is constrained in the guiding channel, and the first end 421 is guided to move in the guiding channel. By configuring the guiding channel in the chamber 20 to realize the constraint and guidance of the movable sleeve 42, when the movable sleeve 42 is led out from the through hole 221 and when the movable sleeve 42 is pushed back into the chamber 20, the movement of the movable sleeve 42 can be made smoother, which is beneficial to reducing the probability of the movable sleeve 42 being bent or stuck in the chamber 20.

[0042] For the selection of the movable sleeve 42, of course, there are various choices. For example, a plastic hose can be used, which can be flexibly bent, but is relatively soft by itself and cannot maintain the required position. Preferably, the movable sleeve 42 in this embodiment adopts a metal hose. By adopting a metal hose for the movable sleeve 42, it can not only be bent in multiple directions at multiple angles, but also maintain its existing shape after bending, so as to realize the fixation of the reading lamp 3 at multiple positions and angles. Moreover, by using a metal hose as the movable sleeve 42, with its own certain structural strength and bendability, the arrangement form of the preset path of the guiding channel arranged in the chamber 20 can be made more flexible, the telescopic movement ability of the movable sleeve 42 in the guiding channel is better, and the smoothness of the movement of the movable sleeve 42 will be further improved during the process of pulling or pushing the movable sleeve 42 in and out of the through hole 221.

[0043] The metal hose is also often called a snake tube, gooseneck tube, universal tube or metal bellows in the art, and there are existing suitable products for selection. For example, products produced by Dongguan Lifesuo Hardware Electronics Co., Ltd. can be used, which can be bent arbitrarily without rebounding, make no noise and have a long service life.

[0044] Based on the case of using a flexible metal hose, such as Figure 3 , Figure 4 and in combination with Figure 6 , Figure 7 and Figure 8 as shown, the lamp holder 22 of this embodiment is arranged in the middle of the ceiling 1, and the guiding channel extends forward from the lamp holder 22 towards the vehicle. By arranging the lamp holder 22 in the middle position of the ceiling 1, through configuring an appropriately long movable sleeve 42 and the necessary redundant length of the wire harness 5 of the reading lamp 3, the movable adjustment range of the reading lamp 3 in the passenger compartment can be made larger. Making the guiding channel extend forward towards the vehicle facilitates arranging the wire harness 5 to the front end position of the ceiling 1, converging with the lines of the electrical components at the in-vehicle rearview mirror, and finally connecting to the vehicle's on-vehicle power supply through the wire arrangement path within the vehicle's front bulkhead.

[0045] Moreover, preferably, the guiding channel can be set into two parts, specifically including a straight section 411 arranged along the front-back direction of the vehicle, and a transition section 412 that is bent and connected between the straight section 411 and the through hole 221. While setting most of the guiding channel as the straight section 411, a bent transition section 412 is arranged between the end of the straight section 411 and the through hole 221, which facilitates the movable sleeve 42 to bend conformally when moving at the transition section 412 and move through smoothly, thereby further improving the smoothness of the guiding movement of the movable sleeve 42 within the guiding channel.

[0046] Regarding the specific configuration method of the above guiding channel, of course, there are various solutions, such as it can be configured in the form of a guide rail or a guide groove. In this embodiment, a fixed sleeve 41 is fixedly arranged in the chamber 20, and the guiding channel is formed within the fixed sleeve 41. By arranging the fixed sleeve 41 in the chamber 20 and using the internal pipe of the fixed sleeve 41 as the guiding channel, not only can a good constraint, guidance, and protection for the movable sleeve 42 be formed; but it is also convenient for technical implementation. In this embodiment, a bracket is arranged on the ceiling 1, and the fixed sleeve 41 is fixedly arranged on the bracket. The bracket includes a plurality of support plates 210 arranged at intervals in the length direction of the fixed sleeve 41, and the fixed sleeve 41 is mounted on each support plate 210. Of course, the fixed sleeve 41 can adopt the form of a straight pipe section as shown in Figure 6 and Figure 7 to only configure the straight section 411 part of the above guiding channel; or as shown in Figure 8 , a section similar to an elbow is arranged at one end of the fixed sleeve 41 close to the through hole 221 for use as the transition section 412 of the guiding channel.

[0047] In addition, limiting structures 410 are provided at both ends of the fixed sleeve 41 in this embodiment, and a limiting protrusion 420 is provided at the first end 421; the limiting protrusion 420 is blocked by the two limiting structures 410, so that the first end 421 is restricted within the fixed sleeve 41. By providing the limiting structures 410 at both ends of the fixed sleeve 41 and cooperating with the limiting protrusion 420 provided at the first end 421 of the movable sleeve 42, the first end 421 can be reliably restricted inside the fixed sleeve 41, preventing the reading lamp 3 from pulling the movable sleeve 42 into the passenger compartment with an excessive length and causing the movable sleeve 42 to disengage from the fixed sleeve 41.

[0048] For the setting of the lamp socket 22 and the installation method of the reading lamp 3 on the lamp socket 22, various forms can be adopted. In this embodiment, as Figure 4 and in combination with Figure 7 shown, the reading lamp 3 includes a lamp body 30 and a connecting portion 31 provided on the back of the lamp body 30; the lamp socket 22 is provided with a receiving groove 220 and a connecting and mating portion; as the reading lamp 3 is installed in place, the lamp body 30 is received in the receiving groove 220, and the connecting portion 31 is connected to the connecting and mating portion. By providing the receiving groove 220 on the lamp socket 22, the lamp body 30 can be received in the receiving groove 220, making the exterior of the ceiling 1 relatively flat and tidy when the reading lamp 3 is installed in place on the lamp socket 22. By providing the connecting portion 31 of the reading lamp 3 on the back of the lamp body 30, the connection and installation structure between the reading lamp 3 and the lamp socket 22 can be better hidden; making the overall appearance of the installed reading lamp 3 more appealing.

[0049] In Figure 7 , the connecting portion 31 is configured as a stud structure with an external thread 310 on its circumferential surface, and the connecting and mating portion includes an internal thread 222 provided on the inner wall of the through hole 221 and matching the external thread 310. This method is convenient for processing and construction. Of course, the connecting portion 31 can also be configured as a chuck that can be snapped into the through hole 221. In this way, while the through hole 221 allows the movable sleeve 42 and the wire harness 5 inside it to pass through, it also constitutes the above-mentioned connecting and mating portion. Using methods such as screwing or clamping to achieve the disassembly and installation of the reading lamp 3 on the lamp socket 22 is simple and convenient to operate, without the need for tools, which is beneficial to improving the use experience and convenience of the reading lamp 3.

[0050] In summary, for the reading lamp assembly of this embodiment, by providing a lamp base 22 with a through hole 221 on the ceiling 1, the reading lamp 3 is detachably arranged on the lamp base 22, and the wire harness 5 is passed through the movable sleeve 42. Then, when the removed reading lamp 3 is pulled, a part of the movable sleeve 42 can be drawn into the passenger compartment, facilitating the convenient movement and adjustment of the position of the reading lamp 3. When the reading lamp 3 is held and moved back to the position of the lamp base 22, the movable sleeve 42 can be pushed back into the chamber 20, and then the reading lamp 3 can be installed on the lamp base 22, realizing the standardized installation and layout of the reading lamp 3, which is beneficial to improving the usability of the reading lamp 3 in the vehicle.

[0051] Embodiment 2

[0052] This embodiment relates to a vehicle, in which the reading lamp assembly in Embodiment 1 is provided.

[0053] By adopting the reading lamp assembly in Embodiment 1, the movable sleeve 42 can extend to increase the movement range of the reading lamp 3. The reading lamp 3 can be moved to places in the vehicle that are easily blocked, and can be stably maintained in the form after being pulled and bent, without the need for passengers to hold it, liberating the passengers' hands, thus conveniently realizing the illumination of areas with insufficient light or being blocked in the vehicle. When the passengers have finished using it, they can push the reading lamp 3 back to the lamp base 22 and install the reading lamp 3 on the lamp base 22. During this process, the movable sleeve 42 and the wire harness 5 will be retracted together to return to the original position.

[0054] For the vehicle of this embodiment, by adopting the above-mentioned reading lamp assembly, the special lighting requirements in the vehicle can be met, and the configured reading lamp 3 has good aesthetics, does not occupy the passenger space in the vehicle, has a simple structure, is easy to operate, and has good cost advantages.
