Description

Technical Field

[0001] This utility model relates to the field of mining machinery technology, specifically to a rearview mirror bracket and an open-pit mine car. Background Technology

[0002] Open-pit mine cars are vehicles used for transporting ore in open-pit mines. During operation, they need to frequently perform actions such as reversing, turning, and changing lanes, which places high demands on good rear visibility to ensure that operators can clearly observe the surrounding environment and avoid accidents.

[0003] In related technologies, mine car rearview mirrors are usually fixedly installed on the platform of open-pit mine cars for the driver to observe the vehicle and road conditions. Mine car rearview mirrors often cannot be adjusted or have limited angle adjustment capabilities, and can only be adjusted intermittently in a single plane, making it difficult to provide a good field of vision when the vehicle is reversing, turning and changing lanes. Utility Model Content

[0004] The problem this invention aims to solve is: how to make the rearview mirror's adjustment angle wider.

[0005] This utility model provides a rearview mirror bracket, including: a two-way tie rod, an ear plate, and a bracket body;

[0006] The bracket body is used to connect to a vehicle, and the bracket body includes a first connecting part and a second connecting part;

[0007] The ear plate is used to connect to the back of the rearview mirror of the vehicle. The ear plate has an elongated slot, and the elongated slot is used to connect to the first connecting part by bolts.

[0008] The bidirectional tie rod includes a rod body, a first screw, a second screw, a fastening nut, a first joint bearing, and a second joint bearing. The first screw and the second screw are coaxially connected to both ends of the rod body. One end of the first joint bearing is threaded to the first screw, and the other end is rotatably connected to the second connecting part. One end of the second joint bearing is threaded to the second screw, and the other end is rotatably connected to the back of the rearview mirror. The fastening nut is threaded to the first screw and / or the second screw. The external threads on the first screw and the second screw have opposite directions of rotation.

[0009] The rearview mirror bracket provided by this utility model has, but is not limited to, the following beneficial effects compared with related technologies:

[0010] The rearview mirror bracket of this utility model, in use, involves adjusting the fastening nuts on the first and / or second screws of the bidirectional pull rod, and adjusting the bolts between the elongated slot of the ear plate and the first connecting part of the bracket body to a loose state. When the position of the bolts between the elongated slot of the ear plate and the first connecting part of the bracket body remains unchanged, a tool (e.g., a wrench) can be used to rotate the rod clockwise or counterclockwise. During the rotation, the rod will drive the first and second joint bearings to move closer or further apart on the corresponding first and second screws, thereby adjusting the length of the bidirectional pull rod and allowing the rearview mirror to be adjusted horizontally. When the bolts between the elongated slot of the ear plate and the first connecting part of the bracket body slide along the elongated slot, and the rod is simultaneously rotated clockwise or counterclockwise using a tool, the length of the bidirectional pull rod is passively adjusted, allowing the rearview mirror to be adjusted vertically. By simultaneously adjusting the position of the bolts between the elongated slot of the ear plate and the first connecting part of the bracket body, as well as the length of the bidirectional pull rod, the rearview mirror can be adjusted to any angle. Finally, tighten the fastening nuts on the first and / or second screws, as well as the bolts between the elongated slot of the ear plate and the first connecting part of the bracket body, to complete the adjustment of the rearview mirror angle. Compared with related technologies, the rearview mirror bracket of this utility model allows for a wider adjustment angle of the rearview mirror, providing good visibility when reversing, turning, and changing lanes in vehicles (such as open-pit mine cars).

[0011] Optionally, the second connecting part includes a top plate, and the main body of the bracket also includes a column. The top plate is connected to the top of the column, and a first pin is provided on the top plate. The end of the first joint bearing away from the rod is rotatably connected to the first pin.

[0012] Optionally, the second connecting part further includes a support plate, the bracket body further includes a first connecting rod, the first connecting rod is connected to the column, the support plate is connected to the first connecting rod, the support plate is provided with a second pin, the support plate is closer to the rearview mirror relative to the top plate, and the support plate is lower than the top plate in the vertical direction;

[0013] Two bidirectional tie rods are provided. One bidirectional tie rod is connected between the first pin and the rearview mirror, and the other bidirectional tie rod is connected between the second pin and the rearview mirror. The bidirectional tie rod connected between the first pin and the rearview mirror is longer than the bidirectional tie rod connected between the second pin and the rearview mirror.

[0014] Optionally, the first connecting part includes a connecting plate, and the bracket body further includes a second connecting rod.

[0016] Optionally, the bracket body further includes a screw plate and a side plate. The screw plate is connected to the lower end of the column, and the side plate is connected to the side wall of the column. The screw plate and the side plate are respectively used to connect to the vehicle.

[0017] Optionally, both the first joint bearing and the second joint bearing include a rod body, a fisheye connector, and a bearing. The fisheye connector is connected to one end of the rod body, and the bearing is disposed on the fisheye connector. The rod body is provided with internal threads.

[0030] 4. Rearview mirror. Detailed Implementation

[0031] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0032] In the description of this utility model, the orientation or positional relationship indicated by terms such as "up", "down", "left", "right", "top", "bottom", "front", "back", "inner" and "outer" is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing this utility model and is not intended to indicate or imply that the device referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the scope of protection of this utility model.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] In the description of this specification, references to terms such as "embodiment," "one embodiment," and "one implementation" indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or implementation is included in at least one embodiment or implementation of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or implementation. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.

[0035] Furthermore, in the attached diagram, the Z-axis represents the vertical direction, that is, the up and down position, and the positive direction of the Z-axis (that is, the direction the arrow of the Z-axis points) represents up, and the negative direction of the Z-axis (that is, the direction opposite to the positive direction of the Z-axis) represents down.

[0036] It should also be noted that the aforementioned Z-axis designation is only for the purpose of facilitating the description of this utility model and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on this utility model.

[0037] For example, vehicles such as open-pit mine cars need to frequently reverse, turn, and change lanes during operation, which places high demands on good rear visibility to ensure that operators can clearly observe the surrounding environment and avoid accidents.

[0038] In related technologies, some mine car rearview mirrors are fixedly mounted on a platform, but the angle of the mirror cannot be adjusted, limiting the driver's field of vision during vehicle operation. Other rearview mirrors use a clamping block at the bottom to hold the mirror firmly onto a cylindrical tube; when the clamping block is loose, the mirror can rotate along the tube. The top is secured with a structure featuring a row of continuous circular holes, allowing adjustment of the tilt angle along the vertical direction by removing the top bolts and selecting different hole positions. This adjustment method requires bolt removal, which is cumbersome. The rearview mirror's angle adjustment is affected by the position of the circular holes, preventing continuous angle adjustment, and the horizontal angle cannot be adjusted.

[0039] In view of the above situation, this utility model proposes a rearview mirror bracket, which is more convenient and has a wider adjustment angle than the traditional rearview mirror adjustment method.

[0040] like Figures 1 to 4 As shown, the rearview mirror bracket of this utility model embodiment includes: a two-way pull rod 1, an ear plate 2, and a bracket body 3;

[0041] The support body 3 is used to connect to a vehicle (e.g., the platform of an open-pit mine car), and the support body 3 includes a first connecting part and a second connecting part;

[0042] The ear plate 2 is used to connect to the back of the rearview mirror 4 of the vehicle. The ear plate 2 has an elongated slot 21, and the elongated slot 21 is used to connect to the first connecting part by bolts.

[0043] The bidirectional tie rod 1 includes a rod body 11, a first screw 12, a second screw 13, a fastening nut 14, a first spherical bearing 15, and a second spherical bearing 16. The first screw 12 and the second screw 13 are coaxially connected to both ends of the rod body 11. One end of the first spherical bearing 15 is threaded to the first screw 12, and the other end is rotatably connected to the second connecting part. One end of the second spherical bearing 16 is threaded to the second screw 13, and the other end is rotatably connected to the back of the rearview mirror 4. The fastening nut 14 is threaded to the first screw 12 and / or the second screw 13. The external threads on the first screw 12 and the second screw 13 have opposite directions of rotation.

[0044] In this embodiment, in conjunction with the appendix Figures 1 to 4 As shown, when using this rearview mirror bracket, adjust the fastening nut 14 on the first screw 12 and / or the second screw 13 of the double-acting tie rod 1 (attached). Figure 4 The fastening nut 14 is threaded onto the first screw 12. Adjust the bolt between the long slot 21 of the ear plate 2 and the first connecting part of the bracket body 3 to a loose state. When the position of the bolt between the long slot 21 of the ear plate 2 and the first connecting part of the bracket body 3 remains unchanged, a tool (e.g., a wrench) can be used to rotate the rod 11 clockwise or counterclockwise. During rotation, the rod 11 will drive the first joint bearing 15 and the second joint bearing 16 to move closer or further apart on the corresponding first screw 12 and second screw 13. This allows adjustment of the length of the bidirectional pull rod 1, enabling the rearview mirror 4 to adjust its angle horizontally. When the bolt between the long slot 21 of the ear plate 2 and the first connecting part of the bracket body 3 slides along the long slot 21, and the rod 11 is simultaneously rotated clockwise or counterclockwise using a tool, the length of the bidirectional pull rod 1 is passively adjusted, allowing the rearview mirror 4 to adjust its angle vertically. Simultaneously adjusting the bolt position between the elongated slot 21 of the ear plate 2 and the first connecting part of the bracket body 3, as well as the length of the bidirectional tie rod 1, allows for adjustment of the rearview mirror 4 at any angle. Finally, tighten the fastening nut 14 on the first screw 12 and / or the second screw 13, as well as the bolt between the elongated slot 21 of the ear plate 2 and the first connecting part of the bracket body 3, to complete the adjustment of the rearview mirror 4 angle.

[0045] It should be noted that the spherical plain bearings (first spherical plain bearing 15 and second spherical plain bearing 16) are spherical sliding bearings, the basic type consisting of inner and outer rings with spherical sliding contact surfaces. Spherical plain bearings mainly consist of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface, capable of withstanding large loads. Depending on their type and structure, they can withstand radial loads, axial loads, or combined radial and axial loads. Because composite materials are inlaid on the outer spherical surface of the inner ring, the bearing can achieve self-lubrication during operation. They are generally used for low-speed oscillating motions and can also perform tilting motions within a certain angle range. They can still operate normally when the misalignment between the support shaft and the housing bore is significant.

[0046] Optionally, the second connecting part includes a top plate 31, and the support body 3 also includes a column 32. The top plate 31 is connected to the top of the column 32. A first pin is provided on the top plate 31, and the end of the first joint bearing 15 away from the rod 11 is rotatably connected to the first pin.

The length of the bidirectional tie rod 1 connected between the first pin and the rearview mirror 4 is greater than that of the bidirectional tie rod 1 connected between the second pin and the rearview mirror 4. By adjusting the lengths of the two bidirectional tie rods 1, the left and right tilt angle of the rearview mirror 4 along the horizontal plane can be adjusted without disassembling the rearview mirror 4.

[0051] Optionally, the first connecting part includes a connecting plate 35, and the bracket body 3 further includes a second connecting rod 36. The second connecting rod 36 includes a first rod portion 361 and a second rod portion 362 connected to each other, and the first rod portion 361 and the second rod portion 362 are arranged at a right angle or an obtuse angle. The first rod portion 361 is connected to the column 32, and the extension direction of the second rod portion 362 is parallel to the extension direction of the column 32. The connecting plate 35 is connected to the second rod portion 362, and the connecting plate 35 has a connecting hole. The connecting hole and the elongated slot 21 are used for bolt connection.

Figure 2 There are 3 connecting plates 35, and each connecting plate 35 is used to connect to the corresponding ear plate 2 by bolts. In this way, the rearview mirror 4 can be adjusted along the vertical front tilt angle by adjusting the bolt position between the connecting plate 35 and the ear plate 2 without disassembling the rearview mirror 4.

[0063] Another embodiment of this utility model provides an open-pit mine car, including the rearview mirror bracket as described above.

[0064] Since the technical improvements and effects achieved by the open-pit mine car are the same as those of the rearview mirror bracket, the technical effects of the open-pit mine car will not be described in detail.
