[0027] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0028] like Figure 1 and Figure 2 As shown, the truck rearview mirror protection device 100 of the embodiment of the present invention is suitable for protecting the truck rearview mirror 200, the rearview mirror 200 includes a mirror body 201 and a mounting frame 202, the mirror body 201 has a mirror surface 2011, the truck rearview mirror protection device 100 includes a protective cover 1, the protective cover 1 is connected to the rearview mirror 200, the protective cover 1 includes a plurality of side walls, the plurality of side walls form a protective cavity 11 for accommodating the mirror body 201, at least two side walls are arranged on both sides of the mirror body 201 relatively in a horizontal direction, at least two side walls are arranged on both sides of the mirror body 201 relatively in a vertical direction, the side walls are spaced apart from the mirror body 201, the protective cavity 11 has an opening 111, and the mirror surface 2011 is arranged at the opening 111.

[0029] The truck rearview mirror protection device 100 of the embodiment of the present invention is suitable for protecting the rearview mirror 200 of a coal mine truck. The protection cover 1 is arranged on the outside of the rearview mirror 200, and the mirror surface 2011 is arranged at the opening 111. The protection cover 1 will not affect the normal use of the rearview mirror 200; when the rearview mirror 200 is close to an obstacle, the protection cover 1 first collides with the obstacle to serve as a warning to the driver so that the driver can make adjustments in time, thereby reducing the risk of collision or scratching of the rearview mirror 200 when the truck is driving in the coal mine, and ensuring the normal use of the truck rearview mirror 200.

[0030] like Figure 1 and Figure 2 As shown, the mounting frame 202 is made of a steel pipe with both ends bent at right angles. Both ends of the mounting frame 202 are mounted on the truck by bolts. The mirror body 201 is rotatably connected to the mounting frame 202. Adjusting the mirror body 201 to a suitable angle allows the driver to clearly see the situation behind the truck, reducing blind spots in the field of vision, thereby improving the safety of vehicle driving.

[0031] In some embodiments, Figure 1 and Figure 2 As shown, the protective cover 1 is a protective net.

[0032] By configuring the protective cover 1 as a protective net, the weight of the protective cover 1 can be greatly reduced, the installation of the protective cover 1 can be facilitated, and the influence of the installation of the protective cover 1 on the rearview mirror 200 can be reduced.

[0033] like Figure 1 and Figure 2 As shown, the protective cover 1 includes four mesh plates 12, two of which are relatively arranged on the upper and lower sides of the mirror body 201, and the other two mesh plates 12 are relatively arranged on the left and right sides of the mirror body 201; it can be understood that the left and right directions refer to the left and right sides of the truck.

[0034] In some embodiments, the protective cover 1 is rotatably connected to the mounting frame 202 , and the rotation axis of the protective cover 1 is parallel to the rotation axis of the mirror body 201 .

[0035] The protective cover 1 is rotatably connected to the mounting frame 202 , and the protective cover 1 can be adjusted according to the angle of the mirror body 201 to prevent the protective cover 1 from blocking the field of view due to a large tilt angle of the mirror body 201 .

[0036] In some embodiments, Figure 3 and Figure 4 As shown, a rotating assembly 2 is provided between the protective cover 1 and the mounting frame 202 . The rotating assembly 2 includes a connecting sleeve 21 and a connecting column 22 . The connecting column 22 is connected to the mounting frame 202 , and the connecting sleeve 21 is rotatably mounted on the connecting column 22 .

[0037] The protective cover 1 is rotatably connected to the mounting frame 202 via the rotating assembly 2, so that the installation of the protective cover 1 is more convenient.

[0038] As an example, Figure 2 and Figure 3 As shown, the connecting column 22 has a through hole running through it along its length direction, and the connecting column 22 is mounted on the mounting frame 202 through the through hole, and the connecting sleeve 21 is rotatably mounted on the connecting column 22; there are two rotating components 2, and the two rotating components 2 are respectively arranged on the mesh plates 12 on the upper and lower sides of the mirror body 201, thereby realizing the stable rotation of the protective cover 1.

[0039] In some embodiments, the protective cover 1 is detachably connected to the connecting sleeve 21 .

[0040] By detachably connecting the protective cover 1 and the connecting sleeve 21 , when the protective cover 1 is damaged by collision, the protective cover 1 and the connecting sleeve 21 can be disassembled, and only the protective cover 1 needs to be replaced, thereby reducing maintenance costs.

[0041] As an example, Figure 2 and Figure 3 As shown, the upper and lower mesh plates 12 of the protective cover 1 are both provided with a clamp 121 , and the protective cover 1 is fixedly connected to the connecting sleeve 21 via the clamp 121 , that is, the protective cover 1 can rotate relative to the mounting frame 202 via the rotating assembly 2 .

[0042] In some embodiments, the connecting column 22 has a first limiting structure, and the connecting sleeve 21 has a second limiting structure. The first limiting structure cooperates with the second limiting structure in a limiting manner. There are multiple first limiting structures, and the multiple first limiting structures are evenly arranged along the circumference of the connecting column 22; and / or there are multiple second limiting structures, and the multiple second limiting structures are evenly arranged along the circumference of the connecting sleeve 21.

[0043] After the protective cover 1 is adjusted to a suitable angle, the protective cover 1 can be positioned through the limiting cooperation of the first limiting structure and the second limiting structure, so that the protective cover 1 is fixed at a certain position; in other words, the protective cover 1 and the mirror body 201 can remain relatively unchanged, and the protective cover 1 can provide better protection for the mirror body 201.

[0044] In some embodiments, one of the first limiting structure and the second limiting structure is a protrusion 221 , and the other is a groove 211 , and the protrusion 221 and the groove 211 are limitedly matched.

[0045] The protective cover 1 is positioned by the cooperation between the protrusion 221 and the groove 211 , which has a simple structure and can reduce production costs.

[0046] As an example, Figure 3 and Figure 4 As shown, the first limiting structure is a protrusion 221, which is fixedly connected to the outer side wall of the connecting column 22, and a plurality of protrusions 221 are evenly arranged along the circumference of the connecting column 22; the protrusion 221 is made of a thin sheet, and the protrusion 221 is semicircular, so as to form a cavity 222 between the protrusion 221 and the outer side wall of the connecting column 22. The second limiting structure is a groove 211, which is provided on the inner side wall of the connecting sleeve 21, and the protrusion 221 can be limitedly matched with the groove 211, and the number of the grooves 211 is equal to that of the protrusions 221, and a plurality of grooves 211 are evenly arranged along the circumference of the connecting sleeve 21, and a limiting portion 212 is formed between two adjacent grooves 211, and the limiting portion 212 is used to limit the protrusion 221.

[0047] There is a gap between the inner wall of the connecting sleeve 21 and the outer wall of the connecting column 22. When the connecting sleeve 21 is rotated relative to the connecting column 22, the protrusion 221 can be elastically deformed toward the cavity 222, so that the protrusion 221 can cooperate with the next groove 211 through the limiting portion 212, thereby realizing the positioning of the protective cover 1 at different angles.

[0048] In some embodiments, the truck rearview mirror protection device 100 also includes a warning component, which includes a strain gauge sensor 3, a controller and an alarm. The strain gauge sensor 3 and the alarm are both electrically connected to the controller, and the strain gauge sensor 3 is arranged on the protective cover 1.

[0049] When the coal mine environment is more complicated, the driver may not be able to detect the collision of the protective cover 1 in time; through the above settings, the strain gauge sensor 3 can detect the deformation of the protective cover 1 when it is deformed, and transmit the signal to the controller. The controller controls the alarm to sound an alarm, thereby reminding the driver.

[0050] Optionally, the controller and the alarm are both arranged in the cab of the truck.

[0051] In this way, the controller and the alarm can be better protected. At the same time, when the alarm sends out an alarm signal, the driver can obtain it in time.

[0052] Optionally, the alarm is an audible and visual alarm.

[0053] In some embodiments, Figure 1 and Figure 2 As shown, there are multiple strain gauge sensors 3 , and at least two strain gauge sensors 3 are respectively arranged on different side walls of the protective cover 1 .

[0054] Through the above arrangement, the multiple strain gauge sensors 3 can monitor the deformation of different side walls of the protective cover 1 , thereby further improving the accuracy of the deformation monitoring of the protective cover 1 .

[0055] As an example, Figure 1 and Figure 2 As shown, four strain gauge sensors 3 are provided on the protective cover 1 , and the four strain gauge sensors 3 are respectively provided on four mesh plates 12 of the protective cover 1 , and all the strain gauge sensors 3 are electrically connected to the controller.

[0056] In some embodiments, Figure 1 and Figure 2 As shown, the mirror body 201 includes an upper mirror body 2012 and a lower mirror body 2013 , and there are two protective covers 1 , which are respectively disposed on the upper mirror body 2012 and the lower mirror body 2013 .

[0057] The protective cover 1 and the mirror body 201 are arranged in one-to-one correspondence, and the two protective covers 1 can be adaptively rotated with the upper mirror body 2012 and the lower mirror body 2013 respectively, so as to prevent the protective cover 1 from blocking the upper mirror body 2012 or the lower mirror body 2013 .
