For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood by specific circumstances.

[0036] The utility model provides a vehicle sunshade roller blind, for details, see Figure 1-2 , Figure 1 The figure shows a schematic diagram of the structure of a car sunshade roller blind in one embodiment of the utility model. Figure 2 Shown as Figure 1 The internal structure diagram of the A part of the vehicle sunshade roller blind of the utility model embodiment comprises a roller blind frame 1 and a roller blind fabric 2, a reel 3 and a roller blind cross bar 4 arranged on the roller blind frame 1.

[0037] Preferably, the roller shutter frame 1 is a rectangular structure, and the roller shaft 3 and the roller shutter cross rod 4 are respectively arranged on two opposite sides of the rectangular structure. Of course, considering that the roof shapes of different car models are different, the shape of the roller shutter frame can also be selected according to actual needs, which will not be elaborated in the embodiments of the utility model.

[0038] One end of the rolling curtain cloth 2 is connected to the rolling curtain cross bar 4, and the other end of the rolling curtain cloth 2 is wound on the reel 3. A reel spring 31 is arranged in the reel 3, and the reel 3 can be used as a rotor to drive the rolling curtain cloth 2 to achieve reeling.

[0039] The rolling blind crossbar 4 is provided with a light assembly; the reel 3 is provided with a coaxial connector assembly, and the reel 3 is provided with an opening that penetrates the inside and outside of the reel 3. The coaxial connector assembly is electrically connected to the light assembly through a connecting assembly led out from the opening. Preferably, the connecting assembly led out from the coaxial connector assembly is led out from the opening, laid flat on the rolling blind fabric, and extends all the way to the rolling blind crossbar.

[0040] The specific structure of the coaxial connector assembly is described in detail below.

[0041] The coaxial connector assembly includes a coaxial connector male head 32 (not shown), a coaxial connector male head housing 33 and a coaxial connector female socket 34 .

[0042] The male coaxial connector 32 is welded with a male coaxial connector lead 35, which is used to connect a power source or a light controller, so as to achieve driving control of the light. The male coaxial connector lead 35 is electrically connected to the connection assembly; the male coaxial connector 32 is rigidly mechanically connected to the male coaxial connector housing 33, and the male coaxial connector 32 is plugged into the female coaxial connector 34, which is a pluggable connection. While achieving electrical connection, the male coaxial connector 32 and the female coaxial connector 34 can rotate 360 ​​degrees. Preferably, the coaxial connector is a 3.5mm round headphone plug in the actual product.

[0043] Furthermore, in the above embodiment, the reel 3 is further provided with a rotating sleeve 36, which is fixedly connected to the reel 3, and the male coaxial connector housing 33 cooperates with the rotating sleeve 36, so that the male coaxial connector 32 can rotate relative to the reel. Of course, in some cases, the rotating sleeve may not be used, and the male coaxial connector housing may directly cooperate with the reel to achieve the same relative rotation function, which is determined by the actual product design requirements and will not be described in detail here.

[0044] Furthermore, in the above embodiment, the connection component is a connecting cable 37. The connecting cable is superior to ordinary wires in terms of flexibility, volume, weight and assembly reliability, and is more suitable for occasions that require frequent movement or are arranged in a limited space.

[0045] Furthermore, in the above embodiment, the coaxial connector assembly further includes a cable connector 38 and a PCB board 39;

[0046] The coaxial connector base 34 and the cable connector base 38 are both welded to the PCB board 39, and one end of the connecting cable 37 is electrically connected to the cable connector base 38, so as to realize the electrical connection from the coaxial connector base 34 to the cable connector base 38. Of course, the above-mentioned PCB board and cable connector are not necessary designs, and in some cases, the connecting cable can be directly welded to the coaxial connector base, which can also realize the same electrical connection function.

[0047] Furthermore, in the above embodiment, a support ring 391 is provided on the PCB board 39. The support ring is used to support the PCB board, thereby ensuring that the rotation axes of the coaxial connector male head and the coaxial connector female seat are both at the axis center of the reel.

[0048] As can be seen from the above, the female end of the coaxial connector is a PCBA assembly, which is preferably installed inside the reel through a bushing. The bushing is fixedly connected to the reel. Assuming that the Z axis is the axis direction of the reel, the assembly and the bushing are movably connected, and a certain gap is left in the X-axis and Y-axis directions. Since the reel rotates relative to the shutter frame, there is a clearance fit between the two. During the rotational motion, the shutter shaft tube will perform a yaw rotation motion relative to the shutter frame. The reserved gap between the bushing and the assembly in the X-axis and Y-axis can absorb the displacement caused by the yaw rotation motion, and can prevent the yaw rotation motion from damaging the coaxial connector.

[0049] Furthermore, in the above embodiment, the roller blind crossbar 4 is also provided with a cable adapter 41, and the other end of the connecting cable 37 is electrically connected to the cable adapter 41. In addition, the lighting assembly includes a plurality of lamp groups 42, and each of the lamp groups 42 is electrically connected to the connecting cable 37. The lighting assembly also includes a lamp group driver 43 corresponding to each of the lamp groups (there is a wire between the lamp group driver and the lamp group for electrical connection); the lamp group driver 43 is electrically connected to the connecting cable 37 (the lamp group driver can drive multiple light source lamp groups at the same time, and each light source lamp group can independently control its color temperature and brightness, so as to achieve a dynamic optical effect. When there are enough light source lamp groups, a pixelated control effect can be achieved). The cable adapter is installed on the roller blind crossbar, and the lamp group driver and multiple lamp groups are also installed on the roller blind crossbar. All lamp groups 42 are arranged on the roller blind crossbar 4, and the optical fiber is led out from the light source of the lamp group and extends backward, and is spread on the entire roller blind fabric 2 according to actual needs. Using multiple light source lamp groups at the same time to achieve lighting effects can avoid the problem of large local thickness and difficulty in rolling up the rolling curtain caused by concentrated optical fibers. Of course, the lamp group driver can be directly designed as an integrated structure with the lamp group, or the lamp group driver can be eliminated and the lamp group can be directly electrically connected.

[0050] It should be noted that the cable adapter can convert the cable connection into an electrical connection plug suitable for the lamp group driver, thereby facilitating the connection. In actual products, the cable adapter may not be used, and the connecting cable can be directly welded or connected to the lamp group driver or the lamp group to achieve electrical connection.

[0051] In the embodiment of the utility model, the connecting cable 37 is placed on the rolling blind fabric 2. The connecting cable 37 can be rolled back on the reel 3 along with the rolling blind fabric 2 when the rolling blind fabric is rolled back, and can also be extended together when the rolling blind fabric 2 is extended.

[0052] In summary, the connecting cable is led out from the opening of the reel, laid flat on the roller blind cloth, and extends all the way to the roller blind crossbar. The roller blind crossbar is provided with a cable adapter plate, a lamp group driver, and a light source lamp group. The cable is electrically connected to the cable adapter plate, the cable adapter plate is electrically connected to the lamp group driver, and the lamp group driver is electrically connected to the light source lamp group. This realizes the electrical connection function of the external cable of the roller blind to the light source through the coaxial connector in the reel. In addition, the male end of the coaxial connector is fixedly connected to the roller blind frame and remains coaxial with the reel. The female end of the coaxial connector is arranged in the reel, and its connection axis is coaxial with the reel tube, so that when the roller blind cloth is rotated and retracted, the male and female ends of the coaxial connector also maintain reliable electrical connection when they rotate relative to each other.

[0053] The utility model provides a car sunshade roller blind, the beneficial effects of which are at least one of the following:

[0054] (1) By adding a coaxial connector assembly inside the reel, the electrical connection function of the external cable of the roller blind is realized through the coaxial connector assembly inside the reel to the light assembly, solving the problem that the traditional automobile sunshade roller blind cannot be connected to the light and cannot realize the dynamic starry sky ceiling;

[0055] (2) The specific structure of the coaxial connector assembly is refined, so that when the roller blind is rotated and retracted, the male end and the female end of the coaxial connector can maintain reliable electrical connection when they rotate relative to each other;

[0056] (3) The lighting assembly is arranged on the roller blind crossbar of the sunshade roller blind. The optical fiber can be led out from the lighting assembly and extended backwards, and then spread over the entire roller blind cloth according to actual needs. At the same time, multiple lighting groups can be used to achieve lighting effects. This can avoid the problem of large local thickness and difficulty in rolling up the roller blind cloth caused by the concentration of optical fibers.

[0057] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
