[0041] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0042] The utility model embodiment provides a mirror rod, referring to Figure 1-3 The mirror rod includes a mirror rod body 1; a first end of the mirror rod body 1 is provided with a ball head structure 3 for connecting to a lens 2; a second end of the mirror rod body 1 is provided with a connecting structure 4 for connecting to a first workpiece, and a weakening structure 5 is provided on the connecting structure 4.

[0043] As an example, the mirror rod is used to connect and support the lens 2, specifically including a mirror rod body 1, and a first end of the mirror rod body 1 is provided with a ball head structure 3, and the ball head structure 3 is used to connect the lens 2, so that the lens 2 can be rotated at multiple angles to adjust the position of the lens 2; the second end of the mirror rod body 1 is provided with a connecting structure 4, and the connecting structure 4 is used to connect the first workpiece to install the mirror rod body 1 on the first workpiece, thereby realizing the installation of the lens 2 on the first workpiece; a weakening structure 5 is provided on the connecting structure 4, so that the overall structure of the mirror rod is simple and the cost is low; when the lens 2 is impacted by a large external force, the connecting structure 4 breaks at the weakening structure 5, and the mirror rod body 1 and the lens 2 rotate in the direction of impact, absorbing the collision energy, and preventing the mirror rod and the lens 2 from falling, thereby achieving the purpose of protecting the occupants.

[0044] In one embodiment, referring to Figure 1-3 The connecting structure 4 includes an inner body 41, an outer body 42 and a connecting arm 43; the outer body 42 is sleeved outside the inner body 41, and the outer body 42 is connected to the mirror rod body 1; one end of the connecting arm 43 is connected to the inner body 41, and the other end of the connecting arm 43 is connected to the outer body 42; the weakening structure 5 includes a weakened through groove 51 formed by the inner body 41, the outer body 42 and the connecting arm 43.

[0045] As an example, the connecting structure 4 includes an inner body 41, an outer body 42 and a connecting arm 43; the inner body 41 is an annular structure, which is used to install and fix the parts of the mirror rod body 1; the outer body 42 is sleeved outside the inner body 41, and the outer body 42 is connected to the mirror rod body 1. Specifically, the outer body 42 is a side plate of the mirror rod body 1, and a through hole is provided on the outer body 42. The inner body 41 is set in the through hole of the outer body 42; then one end of the connecting arm 43 is connected to the inner body 41, and the other end of the connecting arm 43 is connected to the outer body 4 2, the inner body 41, the outer body 42 and the connecting arm 43 are arranged to enclose a weakened through groove 51. Specifically, the connecting arm 43 separates the inner body 41 from the outer body 42 to form a collision energy absorption space. When the lens 2 is impacted by a large external force, the collision force is transmitted to the outer body 42, and then from the outer body 42 to the inner body 41 through the connecting arm 43. The connecting arm 43 breaks, and the mirror rod body 1 and the lens 2 rotate in the direction of the impact, absorbing the collision energy and preventing the mirror rod and the lens 2 from falling, thereby achieving the purpose of protecting the occupants.

[0046] In one embodiment, referring to Figure 1-3 , multiple connecting arms 43 are arranged at intervals along the circumferential direction of the inner body 41 ; two adjacent connecting arms 43 , the outer body 42 and the inner body 41 enclose a weakened through groove 51 .

[0047] As an example, the number of connecting arms 43 is multiple (for example, three), and the multiple connecting arms 43 are arranged at intervals along the circumferential direction of the inner body 41; in this way, two adjacent connecting arms 43, the outer body 42 and the inner body 41 enclose a weakened through groove 51, i.e., a collision energy absorption space. When the lens 2 is impacted by a large external force, the connecting arm 43 breaks, and the mirror rod body 1 and the lens 2 rotate in the direction of the impact to absorb the collision energy and prevent the mirror rod and the lens 2 from falling, thereby achieving the purpose of protecting the occupants.

[0048] In one embodiment, referring to Figure 3 The weakening structure 5 further includes a weakening recess 52 provided at one end where the connecting arm 43 and the outer body 42 meet.

[0049] As an example, the weakening structure 5 also includes a weakening recess 52, which is arranged at one end where the connecting arm 43 connects to the outer body 42. In this way, when the lens 2 is impacted by a large external force, the collision force is transmitted to the outer body 42, and then transmitted from the outer body 42 to the inner body 41 through the connecting arm 43. The setting of the weakening recess 52 makes the connecting arm 43 easier to break, and the mirror rod body 1 and the lens 2 rotate in the direction of the impact to absorb the collision energy and prevent the mirror rod and the lens 2 from falling, thereby achieving the purpose of protecting the occupants.

Among them, the number of connecting side panels 13 can be one or more; for example, when there is one connecting side panel 13, the first end panel 11, the second end panel 12 and one connecting side panel 13 cooperate to form an H-shaped bracket; when there are two connecting side panels 13, the two connecting side panels 13 are arranged opposite to each other, and the first end panel 11, the second end panel 12 and the two connecting side panels 13 cooperate to form a rectangular bracket; when there are three connecting side panels 13, two of the connecting side panels 13 are arranged opposite to each other, and the first end panel 11, the second end panel 12 and the two connecting side panels 13 cooperate to form a rectangular bracket, and the remaining connecting side panel 13 is installed on the rectangular bracket, so that the first end panel 11, the second end panel 12 and the three connecting side panels 13 cooperate to form a hollow three-dimensional structure with an opening, which saves costs while meeting the support strength.
