[0022] like Figure 2 and Figure 3As shown, the present application provides a light-transmitting structure 100 with a changeable pattern, which includes a light-transmitting member 10 and a backlight module 20 with a changeable pattern.

[0023] The backlight module 20 includes a base 21 , a pattern changing component 22 , a soft film 23 , a light guide component 24 and a light source 25 .

[0024] The light guide component 24 is arranged on the base 21, and the pattern transformation component 22 includes two rotating shafts 221 and a driving member 222. The two rotating shafts 221 are respectively arranged on the left and right sides of the light guide component 24. It can be understood that the left and right in this embodiment refer to the left and right in the direction shown in the accompanying drawings. When the light-transmitting structure is placed in different orientations during use, the left and right may also become other relative positions such as right and left, up and down, or front and back, which are not exhaustively described here. At the same time, the corresponding other orientations will also be changed accordingly. For the sake of convenience of expression, the front side of the light-transmitting structure is called the top and the back side of the light-transmitting structure is called the bottom.

[0025] A plurality of groups of patterns are formed on the soft membrane 23. The plurality of groups of patterns can be different colors of the same pattern, the same color of different patterns, or different colors of different patterns. For example, the plurality of groups of patterns can be scene patterns corresponding to seasons, or characteristic patterns of different driving modes of a car. In short, the role of the plurality of groups of patterns in the present application is designed according to actual usage scenarios.

[0026] The two ends of the soft film 23 are respectively connected to the two rotating shafts 221. The part of the soft film 23 located between the two rotating shafts 221 is located above the light guide component 24. The driving member is used to drive at least one rotating shaft 221 to rotate, so that the soft film 23 is rolled up on one of the rotating shafts 21 and unrolled on the other rotating shaft 21 at the same time, so as to change the pattern of the corresponding parts of the soft film 23 and the light guide component 24. The light guide component 24 is used to guide the light emitted by the light source to illuminate the lower end surface of the soft film 23.

[0027] The light-transmitting member 10 is disposed above the soft film 23 , and the light-transmitting member 10 at least includes a transparent portion corresponding to the soft film 23 .

[0028] That is, after the backlight module 20 is turned on, the pattern on the soft film 23 is illuminated and displayed on the light-transmitting member 10. When the pattern needs to be switched, the driving member 222 drives the rotating shaft 223 to rotate and moves the pattern to be displayed between the two rotating shafts 223, thereby realizing the switching of the pattern.

[0029] In an embodiment of the present application, the light guide component 24 includes a diffusion film 241, a light guide plate 242 and a reflective film 243 which are stacked in sequence from top to bottom. The light source 25 is located on one side of the light guide plate 242, and emits the emitted light into the light guide plate 242 from the side of the light guide plate 242. After the light emitted by the light source 25 is emitted into the light guide plate 242 from the side, the reflective film 243 reflects the light upward, thereby increasing the intensity of the light irradiated upward. The diffusion film 241 evenly diffuses the upward light to the entire surface, making the pattern more clearly visible.

[0030] Preferably, the light source 25 is a PCBA with a light-emitting function, which is inserted into one side of the light guide plate 242. The light-emitting part of the PCBA is arranged corresponding to the side of the light guide plate 242. The use of the PCBA with a light-emitting function can reduce the space occupied by the light source, and secondly, the drive component 222 can be controlled by the control function of the PCBA to achieve automatic switching.

[0031] In the present application, the driving member 222 includes at least one motor 2221 , and the motor 2221 is drivingly connected to the rotating shaft 223 to drive the rotating shaft 223 to rotate.

[0032] Optionally, when the soft diaphragm is made of a material with a certain toughness, unwinding and winding at both ends can be achieved with only one motor 2221, but this may cause certain damage to the soft diaphragm itself; therefore, in some embodiments, motors 2221 can be installed at the ends of both rotating shafts 223, and unwinding and winding at both ends can be achieved through the synchronous coordination of the dual motors.

[0033] However, the use of such a micro motor will increase the structural cost. Therefore, in a preferred embodiment of the present application, a driving method of a single motor 2221 and at least one coil spring 2222 is adopted. The two ends of the coil spring 2222 are respectively fixed relative to the two rotating shafts 223 to drive the soft diaphragm 23 to reel in the direction of one of the rotating shafts 223. For example, the motor 2221 is connected to the rotating shaft on the left, and when the coil spring 2222 is installed, the coil spring 2222 drives the soft diaphragm 23 to reel in the direction of the rotating shaft 223 on the right. When the motor 2221 drives the soft diaphragm 23 to reel in the left side, the elastic force of the coil spring 2222 is overcome, and the coil spring 2222 is also reeled on the rotating shaft 223 on the left side. When the motor 2221 drives the soft diaphragm 23 to unreel in the left side, due to the elastic force of the coil spring 2222, the soft diaphragm 23 and the coil spring 2222 are reeled on the rotating shaft on the right, thereby constituting the normal translation of the soft diaphragm 23.

[0034] Preferably, in order to ensure that the front and rear ends of the rotating shaft 223 are subjected to the same force and prevent the rotating shaft 223 from deforming, there are two coil springs 2222 , which are respectively distributed on both sides of the soft diaphragm 23 along the axial direction of the rotating shaft 223 .

[0035] In order to facilitate the installation of the coil spring 2222 and prevent the coil spring 2222 from being offset in the axial direction of the rotating shaft 223, the driving member 222 includes a coil spring sleeve 2223, which is fixedly sleeved on the rotating shaft 223, and limit retaining edges are formed on both sides of the coil spring sleeve 2223.

[0036] The base 21 includes a bottom plate 211, a peripheral retaining ring 212 and a mounting grid 213. The peripheral retaining ring 212 is connected to the outer side of the bottom plate 211, so that the base 21 forms a box structure with an open top. The shape of the box can be a rectangle (such as Fig. 9 ) can also be an irregular polygon (such as Figure 5 As shown), it is better to be able to accommodate the required components, which will not be described in detail here.

[0037] The mounting grid 213 is disposed in the middle of the bottom plate 211 , and the motor 2221 is disposed on the periphery of the mounting grid 213 .

[0038] Furthermore, the base 21 further includes a motor bracket 214 and a shaft bracket 215 . The motor bracket 214 fixes the motor 221 on the bottom plate 211 , and the end of the shaft 223 is rotatably mounted on the shaft bracket 215 .

[0039] More preferably, the light-transmitting member 10 further includes a mounting portion located outside the transparent portion, for mounting the light-transmitting member 10 with other components.

[0040] The light-transmitting structure with changeable patterns provided in the present application separates the pattern from the light-transmitting member 10. The surface of the light-transmitting member 10 has no pattern. A soft film 23 with multiple groups of patterns is provided at the lower end (i.e., the back side) of the transparent member 10. Both ends of the soft film 23 can be rolled up on the rotating shaft 223 at the corresponding end. The rotating shaft is driven to rotate by the motor 2221 and the coil spring 2222 to realize pattern switching. The present application can perform pattern changes without replacing parts, thereby meeting more diverse scene requirements. The structure can be used in automobiles or other devices with scene switching.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
