[0072] Figure 3 Schematic diagram of the structure of the protective device of some embodiments of the present disclosure. Figure 3 As shown, the folding bracket 102 includes two symmetrically arranged first mounting brackets and a crossbeam 306 fixed between the two first mounting brackets, wherein the crossbeam 326 has a hook-shaped first structure 2602 and a second structure (not shown in the figure), and wherein the first structure 2602 and the second structure are used to fix the rolling curtain when the rolling curtain is unfolded.

[0073] Thus, the folding bracket can be unfolded and the roller blind can be pulled out and unfolded in the required scene, and the first structure and the second structure can be fixed on the folding bracket 102 to form a cover to accommodate the steering wheel of the car. Therefore, the protection device can quickly switch to the protection state when there is no safety officer, and restore to the normal presentation state of the steering wheel when there is a person driving or a safety officer, which can meet the needs of fully unmanned driving without affecting the operational convenience of manned driving.

[0074] According to some embodiments, Figure 3As shown, the first mounting bracket includes: a second mounting bracket 308 and a third mounting bracket arranged in parallel, wherein the second mounting bracket 308 is fixed to the bottom of the rolling shutter box shell 201, and the second mounting bracket 308 is provided with a first rotating shaft 315 and a second rotating shaft 318, and wherein the third mounting bracket is provided with a third rotating shaft 316 and a fourth rotating shaft 320; a first articulated bracket 311, the two ends of the first articulated bracket 311 are respectively connected to the first rotating shaft 315 and the fourth rotating shaft 320, so as to be arranged between the second mounting bracket 308 and the third mounting bracket; and a second articulated bracket 310, the two ends of the second articulated bracket 310 are respectively connected to the second rotating shaft 318 and the third rotating shaft 316, so as to be arranged between the second mounting bracket 308 and the third mounting bracket, wherein the first articulated bracket 311 is connected to the second articulated bracket 310 via a hinge shaft 317.

[0075] Figure 4 This is a schematic diagram of a folding bracket of a protective device in some embodiments of the present disclosure in an open state.

[0076] According to some embodiments, in combination Figure 3 and Figure 4 The third mounting bracket includes: a fixed support frame 313; a fixed plate 312, the fixed plate 312 is connected to one end of the fixed support frame 313 by plugging, wherein the fixed plate 312 is provided with a first slot 1202; a fixing pin 319; and an adjustable support frame 314, the adjustable support frame 314 is provided with a second slot 1401, wherein the second slot 1401 is connected to the first slot 1202 through the fixing pin 319, and wherein the movement of the fixing pin 319 in different positions in the first slot 1202 and the second slot 1401 can be used to control the folding and opening of the folding bracket.

[0077] According to some embodiments, a first hole position 801 having a first length is provided on the second mounting bracket 308, wherein the first rotating shaft 315 can slide along the length direction of the first hole position 801, and wherein a second hole position 1201 having a second length is provided on the fixing plate 312, wherein the third rotating shaft 316 can slide along the length direction of the second hole position 1201.

[0078] In the absence of a safety officer in the autonomous driving vehicle, the fixing plate 312 can be lifted up to allow one end of the second articulated bracket 310 to rotate around the second rotating shaft 318, and the other end to slide with the third rotating shaft 316 along the length direction 1201 of the second hole; one end of the first articulated bracket 311 to rotate around the fourth rotating shaft 320, and the other end to slide with the first rotating shaft 315 along the length direction of the first hole 801. Thus, the second articulated bracket 310 and the first articulated bracket 311 can achieve synchronous movement through the hinge shaft 317. The adjustable support frame 314 can be opened by moving the fixing pin 319, thereby achieving the unfolding or folding of the folding bracket.

[0081] Thus, through the design of multiple rotating shafts and hinge shafts, the folding bracket can be flexibly unfolded and folded, thereby realizing the rapid arrangement and storage of the protective device. The design of the adjustable support frame and the fixing pin in the folding bracket enables the height and angle of the folding bracket to be adjusted according to actual needs, thereby providing better adaptability of use.

[0082] The rolling curtain 204 can be pulled out from the opening 401 of the rolling curtain box by pulling the horizontal rod 206 of the rolling curtain, and the rolling curtain 204 can be fixed to the first structure 2601 and the second structure 2602 of the crossbeam 326, so that the rolling curtain and the folding bracket form a cover, thereby protecting the steering wheel. In addition, the use of the crossbeam 326 increases the stability and strength of the folding bracket, so that the rolling curtain can be firmly fixed when unfolded and is not easy to shift.

[0083] According to some embodiments, the folding bracket further includes two fourth mounting brackets 309 respectively connected to one end of the two first mounting brackets, wherein the fourth mounting brackets 309 are used to screw the protective device onto a dashboard of a car.

[0084] According to some embodiments of the present disclosure, a vehicle is also provided, comprising the protective device of any of the aforementioned embodiments.
