Description

Technical Field

[0001] This application relates to the field of forklift technology, specifically to a rearview mirror. Background Technology

[0002] Traditional forklift rearview mirrors often use rectangular flat lenses, which have limited field of vision and large blind spots. Especially when reversing, drivers find it difficult to clearly see what's behind and to the sides, increasing safety hazards. Furthermore, many existing forklift rearview mirrors have fixed installation positions and angles, failing to adapt flexibly to different driver heights, sitting postures, and viewing preferences, making it difficult to adjust to the optimal field of vision and causing inconvenience. Therefore, there is an urgent need to improve the structure of existing rearview mirrors. Utility Model Content

[0003] In view of this, this application designs a rearview mirror to solve the technical problems of limited field of view, large blind spots, and inconvenience caused by fixed installation position and angle of traditional forklift rearview mirrors.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A rearview mirror, comprising:

[0006] A sight mirror, comprising a frame and a lens mounted on the frame, the frame being fixed to the upper beam of the vehicle frame.

[0007] Furthermore, it also includes a bracket pivotally connected to the rear side of the frame, the bracket being fixed to the upper beam.

[0008] Furthermore, it also includes a mounting structure fixed to the upper beam of the vehicle frame, wherein the rotating part of the bracket is rotatably connected to the movable seat of the mounting structure.

[0009] Furthermore, the rotating part is fitted with a wear-resistant sleeve and a bearing, and the outer side of the bearing is limited by an end cap fixed on the movable seat.

[0010] Furthermore, the mounting structure also includes:

[0011] The fixing frame is fixed to the upper beam;

[0012] The T-shaped slider is fixedly connected to the movable seat, and the T-shaped slider can slide in the T-shaped groove of the fixed frame;

[0013] A locking screw is threaded onto the fixed frame, and the bottom of the locking screw can abut against the T-shaped slider to achieve relative fixation between the movable seat and the fixed frame.

[0014] Furthermore, a butterfly spring is fitted onto the locking screw, and the butterfly spring abuts against the head of the locking screw and the top of the fixing frame.

[0015] Furthermore, a locking hole is provided at the top of the T-slot, and the threaded part of the locking screw is threadedly engaged with the locking hole.

[0016] Furthermore, the mounting structure also includes a wear-resistant pad with a groove, and the lower end of the locking screw has a protrusion that matches the groove. The wear-resistant pad can abut against the T-shaped slider.

[0017] Furthermore, the bracket and the rotating part are connected by a connecting part.

[0018] As can be seen from the above technical solution, the advantages of this utility model are:

[0019] 1. Significantly expands field of vision and reduces blind spots: The spherical reflective lens design provides a wider field of vision compared to traditional rectangular flat lenses. Especially when reversing, it allows the driver to observe the rear and side areas more clearly, effectively reducing blind spots and greatly improving operational safety.

[0020] 2. Dual-degree-of-freedom adjustment mechanism, flexible positioning: This application can achieve both pitch angle adjustment and horizontal displacement adjustment, which can adapt to the vision needs of drivers of different heights.

[0021] 3. Stable and reliable adjustment: The wear-resistant sleeve increases the rotational friction to ensure that the pitch angle will not shift due to gravity or vibration after adjustment; the horizontal position is locked by directly pressing the T-shaped slider with the locking screw, which has the characteristics of convenient operation and reliable locking.

[0022] 4. Easy installation: The sliding fit design of the T-slot and T-slider facilitates quick installation and accurate initial positioning. Attached Figure Description

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and their descriptions are used to explain this application, but are not intended to limit it.

[0032] refer to Figures 1 to 6 ,like Figure 1 As shown, this embodiment provides a rearview mirror, including a mirror 3. The mirror 3 mainly consists of a frame 31 and a lens 32 mounted on the frame 31. A bracket 33 is mounted on the rear side of the frame 31, and the end of the bracket 33 has an integrally connected connecting part 34, which is fixed to the upper beam 11 of the forklift frame 1. The mirror 3 is located in the cab of the forklift and in front of the driver. The frame 1 is connected to the cab.

[0033] The lens 32 adopts a spherical shape. Compared with the rectangular lens in the existing technology, the spherical lens can expand the field of vision of the forklift driver, making the rear and side vision more open when reversing, reducing the blind spot of the forklift driver, and reducing the safety hazards when reversing.

[0034] As a preferred option, such as Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the rearview mirror also includes a mounting structure 4, which mainly consists of a fixed frame 41, a movable seat 42, a T-shaped slider 43, and a locking screw 44. The fixed frame 41 is fixed to the upper beam 11. The end of the connecting part 34 has a rotating part 341. A wear-resistant sleeve 37 is fitted on the rotating part 341 and a bearing 35 is installed. The wear-resistant sleeve 37 is accommodated in the receiving groove 421 of the movable seat 42. An end cap 36 is installed on the movable seat 42 near the bearing 35 by a fixing screw 361. The end cap 36 can limit the bearing 35, so that the bracket 33 can drive the entire rearview mirror 3 to rotate, thereby adjusting the pitch angle. By setting the wear-resistant sleeve 37, the rotational friction between the rotating part 341 and the movable seat 42 can be increased, so that a certain external force needs to be applied when adjusting the pitch angle of the rearview mirror 3 to prevent it from rotating on its own. The T-shaped slider 43 is fixedly connected to the rear side of the movable base 42. The T-shaped slider 43 can slide and engage with the T-shaped groove 411 of the fixed frame 41. The T-shaped groove 411 consists of a horizontal groove and a vertical groove that are interconnected. The horizontal groove extends from the front end of the fixed frame 41 to the rear and connects with the vertical groove. The lower end of the vertical groove extends downward to be flush with the bottom surface of the fixed frame 41. The upper end of the vertical groove is a closed blind groove. A locking hole 412 is provided at the blind end of the upper end of the vertical groove. The threaded part of the locking screw 44 is threadedly connected to the locking hole 412. By rotating the locking screw 44, the lower end of the locking screw 44 can be moved down until its bottom abuts against the top surface of the T-shaped slider 43, thereby achieving relative fixation between the T-shaped slider 43 and the fixed frame 41.

[0035] The locking screw 44 consists of a threaded part and a head. The head is used for hand-held force application, and the threaded part is used to connect the fixing bracket 41 and apply pressure to the T-shaped slider 43.

[0036] Preferably, in order to increase the reliability of the connection, a butterfly spring 45 is fitted on the locking screw 44. The butterfly spring 45 abuts between the head of the locking screw 44 and the top of the fixing bracket 41, which can provide a continuous elastic preload, enhance the reliability of locking and prevent loosening due to vibration.

[0037] like Figure 6 As shown, in order to make the locking screw 44 and the T-shaped slider 43 more secure and prevent loosening, the mounting structure 4 also includes a wear-resistant pad 46. The wear-resistant pad 46 has a groove 461, and the lower end of the locking screw 44 has a protrusion 441. The protrusion 441 is adapted to the groove 461 to realize the connection between the wear-resistant pad 46 and the protrusion 441. The wear-resistant pad 46 can abut against the T-shaped slider 43. The wear-resistant pad 46 is made of a material with a high coefficient of friction and excellent wear resistance (such as a specific rubber or engineering plastic), and has the characteristics of low processing cost and easy replacement.

[0038] Instructions for use: By rotating the sight glass 3, the rotating part 341 can rotate within the movable seat 42, thereby adjusting the pitch angle of the sight glass 3. A wear-resistant sleeve 37 is placed between the rotating part 341 and the movable seat 42 to increase the rotational friction between them, ensuring that the sight glass 3 will not loosen after angle adjustment. To adjust the horizontal position of the sight glass 3, first loosen the locking screw 44. The locking screw 44 will then release its pressure on the T-shaped slider 43. At this point, the horizontal position can be adjusted by moving the movable seat 42. After adjustment, tighten the locking screw 44 again.

[0039] This application not only allows adjustment of the tilt angle of the viewing mirror, but also horizontal adjustment, making it easier for the driver to adjust the viewing angle to a more suitable range, thereby increasing the safety and convenience of operation.

[0040] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to the embodiments of this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
