Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicle parts, in particular to an electric vehicle rearview mirror with a protective structure. Background Art

[0002] The rearview mirror is a tool for the driver to directly obtain external information such as the rear, sides and bottom of the car while sitting in the cab seat. When an electric vehicle is in use, in order to ensure safety during use and to be able to observe road conditions in a timely manner, installing an electric vehicle rearview mirror can better achieve the safe use of the electric vehicle and reduce the occurrence of safety accidents.

[0003] In the prior art, a Chinese patent with authorization announcement number CN218141897U discloses an electric vehicle rearview mirror, which includes a rearview mirror, a connecting rod and a fixing seat, wherein the rearview mirror is composed of a mounting seat and a mirror surface, wherein the mirror surface is connected to the mounting seat, wherein the connecting rod is connected to the mounting seat, wherein the fixing seat is connected to one end of the connecting rod away from the mounting seat, wherein a locking member for locking the connecting rod is connected to the mounting seat, wherein one end of the connecting rod away from the mounting seat is connected to a ball head, wherein a spherical groove is provided on the fixing seat, wherein the ball head is movably connected in the spherical groove, and wherein an adjustment component for adjusting the diameter of the spherical groove is provided on the fixing seat. The utility model has the effect of reducing the maintenance cost of electric vehicles.

[0004] The above-mentioned mechanism uses bolts and limit rods to install and fix the rearview mirror and the connecting rod, thereby reducing the maintenance cost. However, in actual use, some rearview mirrors are damaged, including the rearview mirror and the connecting rod. The connecting rod is bent due to the force of the electric vehicle tipping over or the angle is shifted due to a collision, which will cause the connecting rod to be disassembled and replaced together with the rearview mirror. Therefore, it is even more necessary to protect the connecting rod to reduce the bending or angle shift of the connecting rod during use. Utility Model Content

[0005] The utility model aims to provide an electric vehicle rearview mirror with a protective structure to solve the problem in the background art that the connecting rod is bent due to the force of the electric vehicle tipping over or has an angle deviation due to a collision.

[0006] To achieve the above object, the utility model provides the following technical solution: an electric vehicle rearview mirror with a protective structure, comprising a rearview mirror body and a connecting rod, one end of the rearview mirror body is hinged to the connecting rod through a hinge, and a nut is threadedly connected to the lower end of the outer side of the connecting rod;

[0007] The outer side of the connecting rod is covered with a protective sleeve, and the outer side of the protective sleeve is provided with a protective mechanism for preventing the connecting rod from bending, the protective mechanism includes an elastic airbag, and the elastic airbag is fixedly connected to the inside of the connecting rod;

[0008] The top end of the hinge is fixedly connected with a support rod, and the top end of the support rod is slidably connected with an alarm mechanism for preventing the rearview mirror body from excessive rotation.

[0009] Furthermore, the protection mechanism includes a mounting box, and the mounting box is fixedly connected to the outside of the protection sleeve, the inside of the mounting box is slidably connected to a movable block via a piston, and the outside of the movable block is fixedly connected to a buffer plate.

[0010] Furthermore, the cross section of the buffer plate is in an arc shape, and the inner diameter of the buffer plate is larger than the outer diameter of the connecting rod.

[0011] Furthermore, a buffer spring is fixedly connected to the inner side of the buffer plate, and an elastic structure is formed between the buffer spring and the protective sleeve.

[0012] Furthermore, the alarm mechanism includes a limit block, and the limit block is slidably connected to the top end of the support rod, and one side of the support rod and the inner side of the limit block are fixedly connected with corresponding conductive sheets.

[0013] Furthermore, a connecting spring is connected to the lower end of the inner side of the limiting block, and one side of the connecting spring is connected to the upper end of one side of the supporting rod.

[0014] Furthermore, a slide groove is provided at the top of the limit block, and a slider matching the slide groove is fixedly connected to the top of the support rod, and a sliding mechanism is formed between the limit block and the support rod through a sliding connection between the slider and the slide groove:

[0015] 1. The rearview mirror body and the connecting rod are hinged by a hinge, so that the rearview mirror body can be flexibly adjusted to different angles by the hinge. Before the connecting rod is installed, a protective cover is placed on the outside of the connecting rod, so that the elastic airbag inside the protective cover can fit and wrap with the outside of the connecting rod. When the connecting rod is hit, the protective cover and the elastic airbag cooperate with each other to protect it, reducing the bending deformation of the connecting rod due to force and increasing the service life of the connecting rod when in use;

[0016] Furthermore, when the connecting rod is overturned by the electric vehicle or collides with the rearview mirror body, the buffer plate will be stressed, and the buffer spring inside the buffer plate will be stressed to shorten its length, and the buffer plate will move inward, and the movable block will squeeze the gas inside the installation box and transport it to the inside of the elastic airbag, so that the inside of the elastic airbag remains filled with gas. The elastic airbag can more comprehensively wrap and protect the connecting rod, so that when it is hit, it can more effectively buffer the impact force. The cross-section of the buffer plate is an arc, which can more comprehensively shield and protect the connecting rod.

[0017] Furthermore, when the buffer plate or the internal buffer mechanism is damaged, the protective cover is separated from the connecting rod for disassembly, and the protective cover is replaced, which reduces the replacement of the connecting rod and the rearview mirror body, thereby reducing the maintenance cost and making the overall maintenance more convenient;

[0018] 2. By rotating the rearview mirror body, the rear road conditions can be better observed according to different needs. During the rotation process, the mirror surface of the rearview mirror body is easily broken due to excessive rotation and force. Therefore, during the rotation of the rearview mirror body, when the rotation is excessive, pressure will be applied to the limit block, which will be pushed by the rearview mirror body and shorten the length of the connecting spring. At the same time, when the limit block moves to the position limit, the two conductive sheets will contact, thereby issuing a warning alarm to remind the driver that the rotatable angle of the rearview mirror body has reached the limit, avoiding excessive rotation and causing the mirror surface of the rearview mirror body to be broken;

[0019] Furthermore, during the movement of the limit block, the slider and the slide groove can assist the stability of the movement of the limit block, thereby preventing the limit block from offsetting during the sliding process on the surface of the support rod, so that the conductive sheets can fit and conduct electricity more accurately, thereby stably transmitting data information.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Embodiment 1:

[0031] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The technical solution shown is to solve the following problem: the electric vehicle rearview mirror with a protective structure discloses a protective mechanism, including a rearview mirror body 1 and a connecting rod 2, one end of the rearview mirror body 1 is hinged to the connecting rod 2 through a hinge 10, and the lower end of the outer side of the connecting rod 2 is threadedly connected with a nut 3, the outer side of the connecting rod 2 is sleeved with a protective sleeve 4, and the outer side of the protective sleeve 4 is provided with a protective mechanism for preventing the connecting rod 2 from bending, the protective mechanism includes an elastic airbag 6, and the elastic airbag 6 is fixedly connected to the inside of the connecting rod 2.

[0032] In this example, the rearview mirror body 1 and the connecting rod 2 are hinged by a hinge 10, so that the rearview mirror body 1 can be flexibly adjusted to different angles by means of the hinge 10. Before the connecting rod 2 is installed, the protective cover 4 is put on the outside of the connecting rod 2, so that the elastic airbag 6 on the inside of the protective cover 4 can fit and wrap with the outside of the connecting rod 2, so that when the connecting rod 2 is hit, the protective cover 4 and the elastic airbag 6 cooperate with each other and protect it, thereby reducing the bending and deformation of the connecting rod 2 due to force and increasing the service life of the connecting rod 2 when in use.

[0033] Embodiment 2:

[0034] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The technical solution shown is based on Example 1, in order to solve the problem of insufficient buffering performance when a collision occurs in the electric vehicle rearview mirror: the electric vehicle rearview mirror with a protective structure discloses a buffer mechanism, the protective mechanism includes a mounting box 7, and the mounting box 7 is fixedly connected to the outside of the protective cover 4, the interior of the mounting box 7 is connected to a movable block 8 through a piston sliding connection, and the outer side of the movable block 8 is fixedly connected to a buffer plate 5, the cross-section of the buffer plate 5 is arc-shaped, and the inner diameter of the buffer plate 5 is larger than the outer diameter of the connecting rod 2, the inner side of the buffer plate 5 is fixedly connected to a buffer spring 9, and an elastic structure is formed between the buffer spring 9 and the protective cover 4.

[0035] In this example, when the connecting rod 2 is hit by the electric vehicle tipping over or the rearview mirror body 1, the buffer plate 5 will be stressed and the buffer spring 9 on the inside of the buffer plate 5 will be stressed to shorten its length. At the same time, the buffer plate 5 moves inward, and the movable block 8 will squeeze the gas inside the mounting box 7 and transport it to the inside of the elastic airbag 6, so that the inside of the elastic airbag 6 remains filled with gas. The elastic airbag 6 can more comprehensively wrap and protect the connecting rod 2, so that when it is hit, it can more effectively buffer the impact force. The cross-section of the buffer plate 5 is an arc, which can more comprehensively shield and protect the connecting rod 2. At the same time, when the buffer plate 5 or the internal buffer mechanism is damaged, the protective cover 4 is separated from the connecting rod 2 for disassembly, and the protective cover 4 is replaced, thereby reducing the replacement of the connecting rod 2 and the rearview mirror body 1, thereby reducing the maintenance cost and making the overall maintenance more convenient.

[0036] Embodiment three:

[0037] like Figure 3 and Figure 5The technical solution shown is to solve the problem that the rearview mirror body 1 is easily broken and damaged due to excessive angle flipping when the electric vehicle rearview mirror is adjusted: the electric vehicle rearview mirror with a protective structure discloses an alarm mechanism, the top of the hinge 10 is fixedly connected to the support rod 12, and the top of the support rod 12 is slidably connected to the alarm mechanism for preventing the rearview mirror body 1 from excessive rotation, the alarm mechanism includes a limit block 11, and the limit block 11 is slidably connected to the top of the support rod 12, one side of the support rod 12 and the inner side of the limit block 11 are fixedly connected with corresponding conductive sheets 14, the lower end of the inner side of the limit block 11 is connected with a connecting spring 13, and one side of the connecting spring 13 is connected to the upper end of one side of the support rod 12, a slide groove 16 is opened at the top of the limit block 11, and a slider 15 matching the slide groove 16 is fixedly connected to the top of the support rod 12, and the limit block 11 and the support rod 12 are slidably connected through the slider 15 and the slide groove 16 to form a sliding mechanism.

[0038] In this example, by rotating the rearview mirror body 1, the road conditions on the rear side can be better observed according to different needs. During the rotation process, it is easy to cause the mirror surface of the rearview mirror body 1 to be broken due to excessive rotation and force application. Therefore, during the rotation of the rearview mirror body 1, when the rotation is excessive, pressure will be applied to the limit block 11, and the limit block 11 will be pushed by the rearview mirror body 1 and the connecting spring 13 will be forced to shorten its length. At the same time, when the limit block 11 moves to the position limit, the two conductive sheets 14 will contact each other, thereby issuing a warning alarm to remind the driver that the rotatable angle of the rearview mirror body 1 has reached the limit, thereby avoiding excessive rotation and causing the mirror surface of the rearview mirror body 1 to be broken.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
