[0024] The connecting bracket 10 is not higher than the instrument housing 30 and is mounted on the steering column 60 to facilitate its installation and fixation. Furthermore, the gear shift lever 51 is connected to the steering column 60, and the connecting bracket 10 is mounted on the steering column 60. When the user needs to adjust the steering wheel angle and thus adjusts the steering column 60, the connecting bracket 10 and the gear shift lever 51 will move simultaneously with the steering column 60. This linkage between the connecting bracket 10 and the gear shift lever 51 prevents the protective device from failing to protect the gear shift lever 51 due to adjustments to the steering column 60, thus improving the protective effect of the protective device on the gear shift lever 51.

[0025] The first end of the protection support 20 is connected with the connecting support 10 to realize installation and fixation of the protection support 20.

The shielding part 21 comprises a first rod segment 211, two second rod segments 212 and two third rod segments 213. The two third rod segments 213 are respectively arranged on the front and back sides of the second end of the protection support 20, and the two third rod segments 213 are arranged in a direction away from each other, so that the shielding part 21 is larger in size along the front and back directions, the shielding part 21 has a wider coverage area, and the protection effect of the protection device is better.

[0030] Both of the two connecting arms 22 are connected to the connecting support 10, and the two connecting arms 22 are respectively located on the front and back sides of the steering column 60, so as to realize the stable and reliable connection between the protection support 20 and the connecting support 10. The ends of the two connecting arms 22 away from the connecting support 10 are arranged outside the steering wheel mounting surface 31 of the instrument shell 30, and the two connecting arms 22 are respectively connected to the two third rod segments 213 in a one-to-one correspondence, so as to realize the stable and reliable connection between the connecting arms 22 and the shielding part 21. The avoiding space 23 is formed between the two connecting arms 22 for the shuttle shift lever 50 to pass through, so as to avoid the interference or obstruction of the connecting arms 22 to the shuttle shift lever 50. The end of the shuttle shift lever 50 outside the steering wheel mounting surface 31 is provided with a shift handle 51.

[0031] In the embodiments of the present application, please refer to Figure 5 and Figure 6The connecting arm 22 comprises a mounting segment 221, an avoiding segment 222 and a frame connecting segment 223 connected in sequence, the mounting segment 221 is located at the lower side of the instrument shell 30 and connected with the connecting support 10, the frame connecting segment 223 is located at the upper side of the instrument shell 30 and connected with the corresponding third rod segment 213, the avoiding segment 222 is arranged through the instrument shell 30 and is inclined towards the shielding part 21 in the direction from the lower side to the upper side, so that the avoiding segment 222 is located at the side of the shuttle-type gear lever 50 away from the steering column 60 outside the instrument shell 30.

[0032] The mounting segment 221 is located at the lower side of the instrument shell 30, the mounting segment 221 extends along the left-right direction, the mounting segment 221 is connected with the connecting support 10, so as to realize the stable and reliable connection between the connecting arm 22 and the connecting support 10. The frame connecting segment 223 is located at the upper side of the instrument shell 30, the frame connecting segment 223 extends along the left-right direction, and the frame connecting segment 223 is connected with the corresponding third rod segment 213, so as to realize the stable and reliable connection between the connecting arm 22 and the shielding part 21. The avoiding segment 222 is connected between the mounting segment 221 and the frame connecting segment 223, the upper end of the avoiding segment 222 is arranged through the steering wheel mounting surface 31 of the instrument shell 30, and the avoiding segment 222 is inclined towards the shielding part 21 in the direction from the lower side to the upper side, so that the avoiding segment 222 is located at the side of the shuttle-type gear lever 50 away from the steering column 60 outside the instrument shell 30, so that the shielding part 21, the shuttle-type gear lever 50 and the steering column 60 can be arranged in sequence and reasonably laid out, and the shielding part 21 can be located at the side of the shuttle-type gear lever 50 away from the steering column 60.

[0033] In the embodiment of the present application, referring to Figure 3 and Figure 4 , the avoiding segments 222 of the two connecting arms 22 are inclined to each other in the direction from the lower side to the upper side. That is, in the direction from the lower side to the upper side, the avoiding segments 222 of the two connecting arms 22 are inclined to each other, so that the distance between the avoiding segments 222 of the two connecting arms 22 gradually decreases, avoiding interference or obstruction of the connecting arm 22 to the instrument shell 30, and the distance between the frame connecting segments 223 of the two connecting arms 22 is small, so that the protective support 20 is not easy to deform and has higher structural strength.

[0034] In the embodiment of the present application, referring to Figure 3 and Figure 4 , the shielding part 21 and the two connecting arms 22 are integrally formed by bending, so that the assembly step between the shielding part 21 and the two connecting arms 22 is omitted, the assembly error between the shielding part 21 and the two connecting arms 22 is reduced, and the structural stability of the protective support 20 is improved.

[0035] In other embodiments, the shielding part 21 and the two connecting arms 22 can also be designed in a split type, facilitating replacement of the shielding part 21 after wear, and improving the use flexibility of the protection support 20.

[0036] In the embodiments of the present application, referring to Figure 3 , the shielding part 21 is arranged in parallel with the steering wheel mounting surface 31 of the instrument shell 30, facilitating installation and protection of the shielding part 21.

[0037] In the embodiments of the present application, referring to Figure 3 and Figure 4 , the vertical distance between the shielding part 21 and the gear handle 51 is between 100mm and 160mm. If the vertical distance between the shielding part 21 and the gear handle 51 is less than 100mm or greater than 160mm, the protection effect can be poor, and the driver's legs can still touch the gear handle 51. Therefore, by setting the vertical distance between the shielding part 21 and the gear handle 51 to be between 100mm and 160mm, the shielding part 21 can have a better protection effect, and the driver's legs can be prevented from accidentally touching the gear handle 51.

[0038] Specifically, the vertical distance between the shielding part 21 and the gear handle 51 is 100mm, 110mm, 120mm, 130mm, 140mm, 150mm or 160mm.

[0039] In the embodiments of the present application, referring to Figure 5 and Figure 6 , the connecting support 10 includes a connecting plate 11 and a support frame 12.

[0040] The connecting plate 11 is sleeved outside the steering column 60, and the connecting plate 11 is welded with the outer periphery of the steering column 60, so that the connecting plate 11 and the steering column 60 can be stably and reliably connected. The right end of the support frame 12 is detachably connected with the connecting plate 11, facilitating replacement of the support frame 12 after wear. When the user needs to adjust the steering wheel angle and adjust the steering column 60, the support frame 12 can be separated from the connecting plate 11, avoiding interference or obstacles of the support frame 12 to the adjustment of the steering column 60, and improving the use flexibility of the support frame 12. The left end of the support frame 12 is detachably connected with the front baffle 40, facilitating replacement of the support frame 12 after wear. By arranging the support frame 12 to be connected between the connecting plate 11 and the front baffle 40 for support, the strength of the connecting support 10 is improved.
