Description

Technical Field

[0001] The utility model relates to the technical field of automobile starry sky roofs, in particular to a telescopic power supply component and a sunshade starry sky roof. Background Art

[0002] With the advancement of technology, sunshade starry sky roofs in the field of automobile modification are widely used to improve the atmosphere in the car, but many design defects have also appeared. Among them, when installing the sunshade starry sky, because the size of the car sunroof frame is fixed, and the spring tube increases the length of the stator end and the rotor end support, and because the light or power supply that needs to be introduced into the rotor end of the spring tube in the prior art is composed of fixed hardware or bearings, it is necessary to disassemble the car sunroof frame to install the spring tube during installation, or install the rotor end first and then use brute force to pry open the other side to put the stator end of the spring tube in, so that the two ends of the spring tube are fixed on the sunroof frame.

[0003] In CN 217435488U, the power supply between the stator and the rotor is realized by a rotatable conductive slip ring and a rotatable reset spring tube in the end plug. The power line at one end of the conductive slip ring is connected to the light source host, and the power line at the other end is connected to the light source, which solves the problem that the power supply cannot be connected to the rotatable sunshade in the prior art. Although the prior art solves the problem of power supply access, almost all rolling curtains for making starry sky will face the problem of installation and removal of sunshade. Among them, there are limitations on the width of the car sunroof, the size of the spring tube after addition / refitting, and the installation method of fixing the light source or the electric slip ring. In addition, when the after-sales service needs to remove the sunshade with the starry sky top, it is necessary to first pry out the stator end with brute force or decompose the car sunroof frame to extract the rotor end with a fixed length at the other end, and then remove the entire sunshade assembly, which is complicated and risky. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the problem that the existing skylight and spring tube need to be opened with brute force for installation and disassembly due to their relatively fixed sizes, and to provide a telescopic power supply component and a sunshade starry sky ceiling. The telescopic function of the telescopic fixing part simplifies installation and disassembly, reduces risks, and also retains the function of the sunshade to access the power supply.

[0005] The utility model adopts a technical solution to solve its technical problem, which is a telescopic power supply component. The telescopic power supply component includes a male part and a female part that cooperate with each other. The male part is sleeved in the female part, and both ends of the male part extend out of the female part. The outer side of one end of the male part and the female part is connected by a spring. The male part can reciprocate along the female part by external force. An electric slip ring is provided inside the male part, and the outer end of the female part is fixed to the inner wall of the spring tube.

[0006] Furthermore, power lines are provided at two ends of the electric slip ring, namely a stator end power line and a rotor end power line.

[0007] Furthermore, the electric slip ring is fixed on the inner wall of the male component.

[0008] Furthermore, the stator-end power line extends from the wire slot of the spring tube and is connected to the power supply of the sunshade starry sky, and the rotor-end power line is electrically connected to the external power supply.

[0009] Furthermore, the wire trough is arranged on the spring tube close to a side where the telescopic power supply component is installed.

[0010] Furthermore, one end of the spring tube on which the telescopic power supply assembly is installed is a rotor end, the other end of the spring tube is a stator end, and a sunshade starry sky is wrapped around the outside of the spring tube.

[0011] Furthermore, when the spring tube is installed, the male component is retracted into the spring tube, and after installation, the male component pops out to serve as an end plug support.

[0012] A sunshade starry sky ceiling comprises a light source host, a front light source, a spring tube, and a retractable sunshade. A cross bar is arranged at the front end of the sunshade, and a rear end of the sunshade is fixed on the spring tube. The sunshade starry sky ceiling comprises the retractable power supply component.

[0013] Compared with the prior art, an electric slip ring is installed in the male part of the telescopic power supply assembly of the utility model, the power line of the stator end of the electric slip ring is connected to the sunshade starry sky power supply wound on the spring tube, and the power line of the rotor end of the electric slip ring is connected to the external power supply. In addition, the male part and the female part in the telescopic power supply assembly are connected by a spring, which can realize the telescopic of the male part without affecting the connection of the slip ring electricity; when installing the spring tube, first fix the stator end, then press the male part, put the telescopic power supply assembly at the rotor end into the sunshade groove of the car sunroof, and after releasing it, the male part pops out under the restoring force of the spring, and the protruding end of the male part extends into the fixed bracket hole of the sunroof and serves as an end plug to support the rotation of the spring tube; the utility model does not need to disassemble the car sunroof frame or use brute force to open the stator end, and it can be installed by only fixing the stator end and pressing the male part to retract it. For disassembly, it only needs to press the male part to take out the rotor end of the spring tube and disassemble the spring tube, which saves construction time and reduces the risk of disassembly and assembly.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Refer to the attached Figure 1 This embodiment includes a telescopic power supply component. When in use, the telescopic power supply component 1 is fixed to the rotor end 2-2 of the spring tube 2. The other end of the spring tube 2 is the stator end 2-1. The outer side of the spring tube 2 is wrapped with a sunshade starry sky 3. The rotation of the spring tube 2 can drive the sunshade starry sky 3 to move.

[0021] The telescopic power supply assembly 1 includes a male part 1-1 and a female part 1-2 that cooperate with each other. The male part 1-1 is sleeved in the female part 1-2. The length of the male part 1-1 is longer than that of the female part 1-2. Both ends of the male part 1-1 extend out of the female part. The outer side of one end of the male part 1-1 and the female part 1-2 are connected by a spring 1-3. The other end of the male part 1-1 can be pressed by external force to make it reciprocate along the inner wall of the female part 1-2.

[0022] An electric slip ring 1-4 is provided inside the male part 1-1, and power lines are provided at both ends of the electric slip ring 1-4, and the power lines extend out of the two ends of the male part 1-1. Further, the power lines at both ends of the electric slip ring 1-4 are respectively the stator end power line 1-52 and the rotor end power line 1-51. The stator end power line 1-52 extends from the wire groove 2-3 of the spring tube 2 and is connected to the power supply of the sunshade starry sky 3, and the rotor end power line 1-51 is electrically connected to an external power supply (not shown in the figure). The electric slip ring 1-4 is fixed to the inner wall of the male part 1-1.

[0023] The outer end of the mother part 1-2 is fixed to the inner wall of the spring tube 2, thereby fixing the telescopic power supply component 1 inside the spring tube 2. The telescopic power supply component 1 is connected to the spring tube 2, and one end of the spring tube 2 connected to the telescopic power supply component 1 serves as the rotor end 2-2, and the rotor end 2-2 also plays a role in supporting the rotating spring tube 2 and electrifying the sunshade starry sky top.

[0024] Further explanation on the rotor end 2-2 in this embodiment: Strictly speaking, the entire outer tube of the spring tube 2 can be called the rotor end 2-2, because only the stator end 2-1 of the spring tube 2 is fixed, and the outer tube of the spring tube 2 rotates around the central axis of the stator end, so the rotor end 2-2 also includes the telescopic power supply assembly 1 connected to the outer tube, and they are a whole.

[0025] In the telescopic power supply assembly 1 of the utility model, the female part 1-2 is fixed to the spring tube 2, so that the spring tube 2, the male part 1-1, the female part 1-2, the spring 1-3, and the electric slip ring 1-4 become a whole. When the stator end 2-1 of the spring tube 2 is fixed, the telescopic power supply assembly 1 installed at the other end of the spring tube 2 serves as the rotor end 2-2 to support the spring tube 2 to rotate. Since the width of the car sunroof is fixed, and the stator end 2-1 and the male part 1-1 supporting the rotor end 2-2 have extra length, the stator end 2-1 is fixed first during installation, and then the male part 1-1 is pressed to shrink inside the spring tube 2, and the overall length is shortened before being placed in the sunshade slot of the car sunroof (not shown in the figure). When the spring tube 2 and the telescopic power supply assembly 1 are placed in the sunshade slot (not shown in the figure), the male part 1-1 pops out due to the restoring elastic force of the spring 1-3, and the extended end of the male part 1-1 enters the hole of the sunshade bracket (not shown in the figure) as an end plug support.

[0026] The utility model uses one end of the spring tube 2 equipped with the telescopic power supply component 1 as a rotor to rotate around the stator end 2-1 of the spring tube 2, so that when the spring tube 2 is installed, the power access function of the sunshade starry sky 3 is retained without disassembling the skylight frame or prying it open with brute force, thereby improving the efficiency of the sunshade starry sky modification / installation and reducing the risk of damage during modification / installation.

[0027] Furthermore, the retractable power supply assembly 1 of this embodiment can be applied to the modified / installed sunshade starry sky ceiling, which includes a light source main unit, a front light source, a spring tube 2, and a retractable sunshade. A cross bar is provided at the front end of the sunshade, and the rear end of the sunshade is fixed on the spring tube 2.

[0028] Those skilled in the art may make various modifications and variations to the utility model. If these modifications and variations are within the scope of the claims of the utility model and their equivalent technologies, these modifications and variations are still within the scope of protection of the utility model patent.

[0029] The contents not described in detail in the specification are prior art known to those skilled in the art.
