DETAILED DESCRIPTION

[0022] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0023] Embodiments of the present invention: Figure 1-Figure 6 As shown, a fixing structure of an electronic rearview mirror for a commercial vehicle includes an A-pillar sheet metal 1, on which a first projection welding nut 2 and a second projection welding nut 3 are provided, and a connecting bracket body 4 is provided with an A-pillar first connecting hole 5 and an A-pillar second connecting hole 6, in which bolts 7 are installed, and the two bolts 7 are threadedly connected to the first projection welding nut 2 and the second projection welding nut 3, respectively.

[0024] The connecting bracket body 4 is made of die-cast aluminum alloy, and the grade is ADC12. The connecting bracket body 4 made of this material has the advantage of light weight. The connecting bracket body 4 is fixedly installed on the A-pillar sheet metal 1, which can effectively prevent the connecting bracket body 4 and the electronic rearview mirror 14 from shaking, and does not affect the trafficability inside the commercial vehicle cab.

[0025] It should be noted that both the left and right sides of the commercial vehicle cab have A-pillar sheet metals 1 , and the A-pillar sheet metals 1 on the left and right sides of the commercial vehicle cab are respectively installed with electronic rearview mirrors 14 through connecting bracket bodies 4 . Figure 1-Figure 6 What is shown is the structure of the A-pillar sheet metal 1, the connecting bracket body 4 and the electronic rearview mirror 14 on the left side of the commercial vehicle cab. The right side and the left side are symmetrical structures and are not shown in the figure.

[0026] Specifically, a first protrusion 8 and a second protrusion 9 are formed on the side of the connecting bracket body 4 close to the A-pillar sheet metal 1 , the A-pillar first connecting hole 5 is opened on the first protrusion 8 , and the A-pillar second connecting hole 6 is opened on the second protrusion 9 .

[0027] The distance between the center of the first connection hole 5 of the A-pillar and the center of the second connection hole 6 of the A-pillar is greater than 120 mm, and the first protrusion 8 and the second protrusion 9 are both formed with mounting bosses 16 on the surface facing the A-pillar sheet metal 1, and the diameter of the end of the mounting boss 16 abutting against the A-pillar sheet metal 1 is preferably greater than Φ25 mm. This design can fully ensure the strength of the mounting point and avoid the problem of weak strength of the cantilever bracket connection point.

[0028] In addition, in order to ensure the structural strength of the connecting bracket body 4, a first rib 10 is formed at the edge of the connecting bracket body 4, and two second ribs 11 are also formed on the connecting bracket body 4, and the two second ribs 11 are both arranged horizontally.

[0029] In this embodiment, the thickness of the connecting bracket body 4, the first rib plate 10 and the second rib plate 11 is preferably 3.5 mm, the height of the first rib plate 10 and the second rib plate 11 are both greater than 15 mm, and the height of the mounting boss 16 is greater than 25 mm.

[0030] For some vehicle models, the position of the first projection welding nut 2 is set as a double-layer plate structure, and the position of the second projection welding nut 3 is set as a single-layer plate structure. In order to ensure the connection strength of the second projection welding nut 3, it is preferred to weld a reinforcing plate at the position of the second projection welding nut 3.

[0031] Furthermore, two limiting grooves 12 are formed on the side of the connecting bracket body 4 away from the A-pillar sheet metal 1, and the bottoms of the two limiting grooves 12 are provided with electronic rearview mirror mounting holes 13. The back of the electronic rearview mirror 14 has two mounting plates 15, which are plugged and connected to the two limiting grooves 12 respectively and fixed with screws 19.

[0032] The limiting groove 12 is used to limit the mounting plate 15 , and a through hole is provided on the mounting plate 15 . After the mounting plate 15 is installed in the limiting groove 12 , the through hole on the mounting plate 15 is aligned with the electronic rearview mirror mounting hole 13 on the limiting groove 12 , and the mounting plate 15 can be fixed with screws 19 .

[0033] The electronic rearview mirror 14 is a prior art and can be purchased directly. The structure and working principle of the electronic rearview mirror 14 do not belong to the protection scope of this application, and this embodiment does not elaborate on the specific structure and working principle of the electronic rearview mirror 14.

[0034] Furthermore, an A-pillar trim assembly 17 is installed on the A-pillar sheet metal 1 , and two avoidance holes 18 are provided on the A-pillar trim assembly 17 .

[0035] The A-pillar trim assembly 17 is a prior art, and the A-pillar trim assembly 17 is connected to the A-pillar sheet metal 1 by a snap buckle. The A-pillar trim assembly 17 should be installed before installing the connecting bracket body 4. In this way, after the connecting bracket body 4 is installed, the connecting bracket body 4 can also press the A-pillar trim assembly 17 to prevent the A-pillar trim assembly 17 from loosening.

[0036] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the drawings. Any changes made according to the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and drawings, should be within the protection scope of the present invention.
