Description

Technical Field

[0001] This utility model relates to the field of mining special vehicle technology, specifically to a multi-angle observation mirror for auxiliary observation of mining special vehicles. Background Technology

[0002] Specialized mining vehicles refer to vehicles with special functions used in the mining process. These vehicles are typically used for transporting minerals, equipment, and personnel, as well as handling waste in mines. They mainly include: mining dump trucks, mining water trucks, mining rescue vehicles, and mining electric trackless rubber-tired vehicles. The existing technology has the following problems:

[0003] Utility model patent CN212685411U discloses a blind spot mirror mounting assembly for a mining dump truck and the mining dump truck itself. The blind spot mirror mounting assembly includes a blind spot mirror, a fixing rod, a support rod, a support base, and fasteners. The blind spot mirror is mounted on the fixing rod. The fixing rod is mounted on the support rod. The support rod has a support base. The support base is fixed to the front guardrail of the cab by fasteners, and the mounting angle of the support rod is adjusted by tightening or loosening the fasteners. Adjusting the mounting angle of the support rod adjusts the viewing angle of the blind spot mirror. This utility model features a simple and reasonable structure, safety, and reliability. The viewing angle can be adjusted according to actual conditions. It avoids unnecessary dangers to the driver due to obstructed vision in blind spots, providing effective protection for the safety of the vehicle and mine workers, and meeting the requirements of a blind spot mirror mounting assembly for a mining dump truck.

[0004] While the aforementioned patents can achieve blind spot observation, the current technology is not comprehensive and has the following drawbacks: Since the viewing angle of the overall blind spot mirror can only be adjusted by adjusting the installation angle of the support rod, it is inconvenient to tighten or loosen the fasteners each time it is adjusted. At the same time, it cannot be adjusted while driving a mining dump truck, which affects the adjustment efficiency. In addition, the blind spot mirrors in the aforementioned patents can only observe in a single direction and cannot observe different angles of vision at the same time. The viewing angle of blind spot auxiliary observation has certain limitations, which affects driving safety. Utility Model Content

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand

[0026] Understood. The present invention will now be further described in conjunction with specific implementation methods.

[0027] like Figure 1 , Figure 2As shown, this utility model provides a multi-angle observation mirror for auxiliary observation of mining special vehicles, including an observation mirror support plate 1. A rear observation mirror mechanism 2 is provided on the top front side of the observation mirror support plate 1, a front observation mirror mechanism 3 is provided on the top rear side of the observation mirror support plate 1, and a mounting mechanism 4 is provided on the left side of the observation mirror support plate 1. The observation mirror support plate 1 has a motor compartment 11. The rear observation mirror mechanism 2 includes a servo motor 21, which is fixedly installed on the top front side of the inner wall of the motor compartment 11. The output shaft of the servo motor 21 passes through to the top of the observation mirror support plate 1 and is fixedly installed with a support rod 23. A mirror rear plate 24 is fixedly installed on the top front side of the support rod 23. A rearview mirror 25 is fixedly installed on the upper front side of 4. An adjustable mirror 26 is movably installed on the lower front side of the rear mirror plate 24. The front observation mirror mechanism 3 includes a servo motor 31. The servo motor 31 is fixedly installed on the rear side of the bottom of the inner wall of the motor compartment 11. The output shaft of the servo motor 31 passes through to the top of the observation mirror bracket plate 1 and is fixedly installed with a bracket rod 33. The other end of the bracket rod 33 is fixedly installed with the rear mirror plate 34. The front observation mirror 35 is fixedly installed on the front side of the rear mirror plate 34. An encoder 22 is provided on the outer wall of the servo motor 21. An encoder 32 is provided on the outer wall of the servo motor 31. Both the servo motor 21 and the servo motor 31 are powered by an external power supply through wires.

[0028] When operating a mining special vehicle, the rear view of the vehicle can be observed through the rearview mirror 25 on the front side of the mirror rear panel 24, while the front view can be observed through the front observation mirror 35 fixed on the front side of the tilted mirror rear panel 34. At the same time, the mirror rear panel 24 as a whole can generate an electrical signal to the encoder 22 to precisely control the speed of the servo motor 21, thereby controlling the rotation of the mirror rear panel 24 through the support rod 23, so as to facilitate quick adjustment of the observation angle of the rearview mirror 25. Similarly, the encoder 32 set on the outer wall of the servo motor 31 can control the servo motor 31 to drive the support rod 33 to rotate, so as to facilitate quick adjustment of the observation angle of the front observation mirror 35.

[0029] like Figure 3 As shown, a base plate 241 is fixedly installed on the lower rear side of the mirror back plate 24. An electric push rod 242 is fixedly installed on the top of the base plate 241. A movable rod 244 is movably installed on the front side of the output end of the electric push rod 242. The mirror back plate 24 has a through movable groove 243. The movable groove 243 is located on the rear side of the adjustable mirror 26. One end of the movable rod 244 away from the output end of the electric push rod 242 passes through the movable groove 243 to the front side of the mirror back plate 24 and is movably connected to the rear side of the adjustable mirror 26.

[0030] By activating the electric push rod 242 at the top of the base plate 241, the rear end of the movable rod 244 is lowered. The movable rod 244 is connected to the adjustable mirror 26, which can be squeezed and rotated downwards. This allows the driver of the mining special vehicle to use the adjustable mirror 26 to see through the ground conditions on both sides of the vehicle, increasing the safety of driving in the mine tunnel.

[0031] like Figure 4 , Figure 5 , Figure 6 As shown, a plug 12 is fixedly installed on the left side of the observation mirror support plate 1. Positioning grooves 121 are provided on both the front and rear sides of the plug 12, and fixing grooves 122 are provided on both the top and bottom sides of the plug 12. The mounting mechanism 4 includes a mounting plate 41. The mounting plate 41 has four through bolt holes 42 arranged in a rectangular array. A docking plate 43 is fixedly installed on the right side of the mounting plate 41. A slot 44 is provided on the right side of the docking plate 43, and the plug 12 engages with the slot 44. The docking plate 43 has two spring chambers 431, located on the front and rear sides of the slot 44 respectively. A spring 432 is fixedly installed on the inner wall of the spring chamber 431 away from the slot 44. A pressure plate 433 is fixedly installed on the other end of the spring 432. A double-ended spring is fixedly installed on the side of the pressure plate 433 away from the spring 432. The inclined plate 434 has two double inclined plates 434. The ends of the two inclined plates 434 away from the pressure plate 433 respectively penetrate into the inner cavity of the slot 44 and are engaged with the two positioning slots 121. The docking plate 43 has a control compartment 435. The control compartment 435 is located on the left side of the slot 44. The bottom of the inner wall of the control compartment 435 is movably installed with a positive and negative threaded rod 436. The top of the positive and negative threaded rod 436 penetrates into the top of the docking plate 43 and is fixedly installed with a knob 437. The upper and lower sides of the outer wall of the positive and negative threaded rod 436 are respectively provided with threaded walls with opposite threads. The outer walls of the two threaded walls are threaded with a moving plate 438. The opposite sides of the two moving plates 438 are fixedly installed with a fixing plate 439. The opposite ends of the two fixing plates 439 respectively penetrate into the inner cavity of the slot 44 and are engaged with the two fixing slots 122.

[0032] During installation, four bolts are first used to pass through the four bolt holes 42 in the mounting plate 41 to fix the entire mounting plate 41 and the docking plate 43 to both sides of the vehicle window. Then, the insert 12 can be directly aligned with the slot 44 and inserted. The right slope of the two double-sloped locking blocks 434 in the slot 44 is pressed, so that the double-sloped locking blocks 434 press against the pressure plate 433 in the spring compartment 431, thereby compressing the spring 432. After the insert 12 is fully inserted into the slot 44, the spring 432 rebounds and the double-sloped locking blocks 434 are locked into the positioning groove 121, temporarily limiting the insert 12 and preventing it from shaking and falling off during the next tightening step. Then, the knob 437 on the top of the docking plate 43 can be rotated to control the inner cavity of the control compartment 435. Rotating the positive and negative threaded rod 436 allows the two moving plates 438 to move closer together by connecting the opposite threads on the upper and lower sides of the outer wall of the positive and negative threaded rod 436 with the threads of the moving plate 438. This causes the two fixed plates 439 to engage with the fixed grooves 122 on the upper and lower sides of the insert block 12, thus fixing the insert block 12 and completing the installation between the observation mirror bracket plate 1 and the docking plate 43. For disassembly, simply reverse the knob 437 to reverse the positive and negative threaded rod 436, causing the two moving plates 438 to move in opposite directions and causing the fixed plates 439 to disengage from the fixed grooves 122, releasing the restriction on the insert block 12. This allows the observation mirror bracket plate 1 to be removed directly, facilitating quick maintenance of the rear observation mirror mechanism 2 or the front observation mirror mechanism 3.

[0033] The working principle of this multi-angle observation mirror, used for auxiliary observation in mining special vehicles, will be explained in detail below.

[0034] like Figure 1-6As shown, when operating a mining special vehicle, the rear view of the vehicle can be observed through the rearview mirror 25 on the front side of the mirror rear panel 24, while the front view can be observed through the front observation mirror 35 fixed on the front side of the tilted mirror rear panel 34. Simultaneously, the mirror rear panel 24 as a whole can generate an electrical signal to the encoder 22 to precisely control the speed of the servo motor 21, thereby controlling the rotation of the mirror rear panel 24 via the support rod 23, facilitating quick adjustment of the observation angle of the rearview mirror 25. Similarly, the encoder 32 installed on the outer wall of the servo motor 31 can control the servo motor 31 to drive the support rod 33 to rotate, thus facilitating quick adjustment of the rearview mirror 25. The observation angle of the front observation mirror 35 can be quickly adjusted. At the same time, the rear end of the movable rod 244 can be lowered by activating the electric push rod 242 on the top of the base plate 241. The front end of the movable rod 244 is connected to the adjustable mirror 26, so the adjustable mirror 26 can be pressed down and rotated. This allows the driver of the mining special vehicle to see the ground conditions on both sides of the vehicle through the adjustable mirror 26, increasing the driving safety in the mine tunnel. During installation, four bolts can be used to fix the entire mounting plate 41 and the docking plate 43 to both sides of the vehicle window by passing through the four bolt holes 42 in the mounting plate 41. Then, the insert 12 can be directly aligned with the slot 44 and inserted. The two double-sloped locking blocks 434 inside the slot 44 are pressed against the right slope, causing the double-sloped locking blocks 434 to press against the pressure plate 433 inside the spring chamber 431. This compresses the spring 432, and after the insert 12 is fully inserted into the slot 44, the spring 432 rebounds, causing the double-sloped locking blocks 434 to engage in the positioning groove 121, temporarily limiting the insert 12 and preventing it from shaking and falling off during the next tightening step. Then, the knob 437 on the top of the docking plate 43 can be rotated to rotate the positive and negative threaded rod 436 inside the control chamber 435. The opposite threads on the upper and lower sides of the outer wall of the positive and negative threaded rod 436 interact with the... The threaded connection of the movable plate 438 can control the two movable plates 438 to move closer to each other, and drive the two fixed plates 439 to be inserted into the fixed grooves 122 on the upper and lower sides of the insert block 12, thus completing the fixing of the insert block 12 and completing the installation between the observation mirror bracket plate 1 and the docking plate 43. When disassembling, simply reverse the knob 437 to drive the forward and reverse threaded rod 436 to reverse, thereby causing the two movable plates 438 to move in opposite directions and drive the fixed plates 439 to disengage from the fixed grooves 122, releasing the limitation on the insert block 12, so that the observation mirror bracket plate 1 can be directly removed, which facilitates quick maintenance of the rear observation mirror mechanism 2 or the front observation mirror mechanism 3.

[0035] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
