Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, and in particular to an easy-to-use electric loader cab door. Background Technology

[0002] Electric loaders are engineering machines that use electricity as their main power source for loading, unloading, handling, and stacking bulk materials. They are widely used in industries such as construction, mining, port logistics, municipal engineering, and agricultural production. The cab is not only an important part of the loader but also the core space for the operator. The design of its components greatly affects the work efficiency, operational safety, and personnel comfort. The cab door is also an important part of the operation. It is not just a passage to enter the cab but also an important barrier to protect the safety of the operator's working environment and reduce the impact of the external environment on the operator.

[0003] Most current cab doors use large glass panels. This design has both advantages and disadvantages. The advantages include: first, it provides the driver with a good field of vision; second, it allows for better lighting and ventilation in the cab; and third, the large glass panel allows the driver to make informed decisions in inclement weather. However, the disadvantages are also significant. First, when the loader is working outdoors and sunlight shines on the glass, it reflects light, which can directly hit the operator's eyes, potentially causing temporary blurred vision or blind spots, increasing the risk of collision. Second, to meet deadlines, operators need to stay in the cab for extended periods; a large glass panel can hinder operator rest and privacy. Utility Model Content

[0004] To overcome the drawbacks of a loader cab door, such as sunlight reflecting off the glass when the loader is working outdoors, which can cause temporary visual blurring or blind spots and increase the risk of collisions; and the disadvantage of a large glass cab that is not conducive to the operator's rest or privacy when the operator needs to stay in the cab for a long time in order to meet the project schedule, an easy-to-use electric loader cab door is provided.

[0005] Technical Solution: A user-friendly electric loader cab door includes a first cab door and a frame. The frame is fixedly connected to one side of the first cab door. A second cab door is also included. Sliding grooves are provided at the bottom of the inner walls of both the first cab door and the frame. The second cab door is slidably connected within the sliding grooves of the first cab door and the frame. A telescopic sealing strip is provided between one side of the second cab door and the frame. A first sealing plate and a second sealing plate are fixedly connected to one side of the first cab door. The opposing portions of the first and second sealing plates are in contact with the second cab door. Both ends of the first and second sealing plates are fixedly connected to the frame. First handles are provided on both sides of the second cab door. A shielding mechanism for reducing light intensity and protecting privacy is provided on one side of the first cab door.

[0006] Furthermore, the shielding mechanism includes a rack plate, a rack plate fixedly connected to one side of the bottom of the second cab door, a first rotating rod rotatably connected to the bottom of the inner wall of the first cab door, a first gear fixedly connected to the outer wall of the first rotating rod, the first gear meshing with the rack plate, a second gear fixedly connected to the top of the first rotating rod, a first fixing plate fixedly connected to one side of the top of the first cab door, a second rotating rod rotatably connected through the top of the first fixing plate, a third gear fixedly connected to the top of the second rotating rod, and the third gear meshing with the second gear.

[0007] Furthermore, the shielding mechanism also includes a threaded rod, with the threaded rod fixedly connected to the bottom of the second rotating rod. A second fixed plate is rotatably connected to the bottom of the threaded rod. One side of the second fixed plate is fixedly connected to one side of the first driver's cab door. A shield is fixedly connected to one side of the frame. A third gear is located inside the shield. A first semi-circular cover is fixedly connected to one side of the first driver's cab door. The threaded rod is located inside the first semi-circular cover. The bottom of the first semi-circular cover abuts against the second fixed plate. A third fixed plate is fixedly connected to one side of the first driver's cab door. A sliding rod is fixedly connected to the bottom of the third fixed plate. A fourth fixing plate is fixedly connected to the bottom end. One side of the fourth fixing plate is fixedly connected to the first driver's cab door. A second semi-circular cover is fixedly connected to one side of the first driver's cab door. The bottom of the second semi-circular cover abuts against the fourth fixing plate. The sliding rod is located inside the second semi-circular cover. Long slots are opened through the outer walls of the first and second semi-circular covers. A movable plate is threadedly connected to the outer wall of the threaded rod. One end of the movable plate is slidably connected to the sliding rod. The movable plate is located at the long slot of the first and second semi-circular covers and is slidably connected to the long slot. A hook is fixedly connected to the top of the movable plate.

[0008] Furthermore, the shielding mechanism also includes a fifth fixed plate. The fifth fixed plates are symmetrically fixed to one side of the first driver's cab door. One side of each of the two fifth fixed plates abuts against the first fixed plate and the third fixed plate, respectively. A third rotating rod is rotatably connected between the two fifth fixed plates. Torsion springs are sleeved on both ends of the third rotating rod. One end of each of the two torsion springs is connected to the two fifth fixed plates. A shielding net is provided on the outer wall of the third rotating rod. A connecting frame is provided at one end of the shielding net. A retaining ring is fixed to one end of the connecting frame. The retaining hook engages with the retaining ring.

[0009] Furthermore, it also includes a first locking block, which is fixedly connected to one side of the second driver's cab door. A special-shaped through groove is opened on one side of the inner wall of the frame. An arc-shaped slide is slidably connected in the special-shaped through groove of the frame. Sliding columns are slidably connected through both the upper and lower ends of the arc-shaped slide. A second locking block is fixedly connected to one end of each of the two sliding columns. When the first locking block moves, it can contact the two second locking blocks respectively. A stop block is fixedly connected to the end of each of the two sliding columns away from the second locking blocks. A spring is sleeved on the outer wall of each of the two sliding columns. One end of the spring is connected to the arc-shaped slide, and the other end of the spring is connected to the second locking block.

[0010] Furthermore, it also includes a protective shell. The protective shell is installed at the irregular through groove of the frame. A slot matching the first locking block is opened through one side of the protective shell. A second handle is slidably connected through both sides of the protective shell. The two second handles are fixed to the two sides of the bow-shaped slide respectively. A limit groove is opened on one side of the frame. A locking plate is slidably connected in the limit groove of the frame. When the locking plate moves, it can contact one of the second handles.

[0011] Beneficial effects: 1. This utility model achieves the opening and closing of the cab door simply and conveniently by sliding the second cab door at the sliding groove between the first cab door and the frame. The driver's opening and closing of the cab door drives the expansion and contraction of the screen net, which blocks the glass on the first cab door. While reducing the light intensity, it also protects the driver's privacy and avoids the reflection of sunlight on the glass. Reflected light is more likely to shine directly into the operator's eyes and may cause temporary visual blurring. The push-pull door structure eliminates the impact on the driver's position when opening and closing the cab door in the traditional way. With the second cab door and the first cab door fitting together, the space for entering and exiting the cab is larger than that of the current cab door structure, making it easier for drivers of different heights to enter and exit the cab.

[0012] 2. This utility model utilizes the cooperation of a first locking block and two second locking blocks. When the first locking block enters the slot of the protective shell, the inclined surface of the first locking block contacts and presses against the inclined surfaces of the two second locking blocks. At this time, the two second locking blocks are pushed away from each other by force, and the two second locking blocks respectively drive the two sliding columns to move. The spring is compressed and deformed by force. At this time, the second cab door continues to move, and the inclined surface of the first locking block disengages from the inclined surfaces of the two second locking blocks. The spring is no longer under force, and it drives the two second locking blocks to reset. At this time, the flat surface of the first locking block abuts against the flat surface of the two second locking blocks respectively, and initially locks the second cab door. When the driver enters the cab, he pushes the locking plate to slide in the limiting groove of the frame until the locking plate passes through one of the second handles, blocking the second handle and preventing the second cab door from being opened from the outside. This avoids the driver being disturbed by the outside world when resting in the cab of the electric loader, thus protecting the driver's privacy. Attached Figure Description

[0025] The shielding mechanism also includes a fifth fixing plate 24. The fifth fixing plates 24 are symmetrically fixed to one side of the first driver's cab door 1. The two fifth fixing plates 24 abut against the first fixing plate 11 and the third fixing plate 18 on one side respectively. A third rotating rod 25 is rotatably connected between the two fifth fixing plates 24. Torsion springs are respectively sleeved at both ends of the third rotating rod 25. One end of the two torsion springs is connected to the two fifth fixing plates 24 respectively. A shielding net 26 is provided on the outer wall of the third rotating rod 25. The shielding net 26 is made of polyester non-woven fabric, which can effectively block sunlight to protect privacy without obstructing the view. A connecting frame 27 is provided at one end of the shielding net 26. The connecting frame 27 is made of fiberglass, which is highly elastic, tough, and resistant to bending. A retaining ring 28 is fixed to one end of the connecting frame 27. The retaining hook 23 is engaged with the retaining ring 28.

[0026] It also includes a first locking block 29, which is fixedly connected to one side of the second driver's cab door 3. The first locking block 29 has inclined surfaces on both sides and a flat surface on one side. A special-shaped through groove is opened on one side of the inner wall of the frame 2. An arc-shaped slide 30 is slidably connected in the special-shaped through groove of the frame 2. Sliding columns 32 are slidably connected through both the upper and lower ends of the arc-shaped slide 30. A second locking block 33 is fixedly connected to one end of each of the two sliding columns 32. One side of the second locking block 33 is inclined and the other side is flat. When the first locking block 29 moves, the inclined surfaces on both sides can contact the inclined surfaces on one side of the two second locking blocks 33 respectively. A stop block is fixedly connected to the end of each of the two sliding columns 32 away from the second locking block 33 to limit the two sliding columns 32 and prevent them from detaching from the arc-shaped slide 30. A spring is sleeved on the outer wall of each of the two sliding columns 32. One end of the spring is connected to the arc-shaped slide 30 and the other end of the spring is connected to the second locking block 33.

[0027] It also includes a protective shell 34. The protective shell 34 is installed in the irregular through groove of the frame 2. A slot matching the first locking block 29 is opened through one side of the protective shell 34. The two sides of the protective shell 34 are slidably connected to the second handle 31. The two second handles 31 are fixed to the two sides of the bow-shaped slide 30 respectively. A limit groove is opened on one side of the frame 2. A locking plate 35 is slidably connected in the limit groove of the frame 2. When the locking plate 35 moves, it can engage with one of the second handles 31.

[0028] Initially, the second cab door 3 is open. When the driver needs to work or rest, the driver enters the electric loader cab through the gap between the second cab door 3 and the frame 2, and then pulls the first handle 6. The second cab door 3 slides at the groove between the first cab door 1 and the frame 2, and the telescopic sealing strip retracts. At the same time, the sliding of the second cab door 3 causes the rack plate 7 and the first locking block 29 to move synchronously and move closer to the protective shell 34. The rack plate 7 moves and engages the first gear 9 to rotate. The first gear 9 drives the first rotating rod 8 and the second gear 10 to rotate synchronously. The rotation of the second gear 10 engages the third gear 13 to rotate. The third gear 13 drives the second rotating rod 12 and the threaded rod 15 to rotate synchronously. The threaded transmission moving plate 22 of rod 15 slides on the slide rod 19. At the same time, the moving plate 22 slides along the long groove of the first semi-circular cover 17 and the second semi-circular cover 21. The sliding of the moving plate 22 drives the hook 23 to move. The hook 23 drives the retaining ring 28 to move downward. The retaining ring 28 drives the shielding net 26 to unfold and move downward through the connecting frame 27. At the same time, the shielding net 26 is forced to drive the third rotating rod 25 to rotate synchronously. The torsion spring is deformed by force. When the first retaining block 29 enters the retaining groove of the protective shell 34, the inclined surface of the first retaining block 29 contacts and presses the inclined surfaces of the two second retaining blocks 33. At this time, the two second retaining blocks 33 are forced to move away from each other. The two second retaining blocks 33 respectively drive the two sliding columns 32 to move. The spring is compressed and deformed by force. At this time, the second driver's cab door 3 continues to move. As the inclined surface of the first locking block 29 disengages from the inclined surfaces of the two second locking blocks 33, the springs are no longer under force, causing the two second locking blocks 33 to reset. At this point, the flat surfaces of the first locking block 29 abut against the flat surfaces of the two second locking blocks 33, initially locking the second driver's cab door 3. Simultaneously, the moving plate 22 moves to the end of the long slots of the first semi-circular cover 17 and the second semi-circular cover 21, and the shielding net 26 fully unfolds, blocking the glass on the first driver's cab door 1. This reduces light intensity and protects the driver's privacy. Subsequently, the driver pushes the locking plate 35, which slides within the limiting slot of the frame 2 until it passes through one of the second handles 31, blocking the second handle 31 and allowing the second driver's cab door 3 to open. The cab cannot be opened from the outside, preventing disturbance to the driver while resting in the cab of the electric loader and protecting the driver's privacy. When the driver needs to leave the cab, first pull the locking plate 35 to release the restriction on one of the second handles 31. Then pull the second handle 31, which moves the bow-shaped slide 30, the sliding column 32, and the second locking block 33. The two second locking blocks 33 are displaced from the first locking block 29 at their planes, releasing the lock on the first locking block 29. Then, the driver pulls the first handle 6 to slide the second cab door 3, extending the telescopic sealing strip. The sliding of the second cab door 3 moves the rack plate 7 and the first locking block 29 away from the protective shell 34. The rack plate 7 slides and engages the first gear 9 to rotate in the opposite direction.The first gear 9 drives the second gear 10 to rotate synchronously in the opposite direction via the first rotating rod 8. The second gear 10 meshes with the third gear 13 to rotate synchronously in the opposite direction. The third gear 13 drives the threaded rod 15 to rotate in the opposite direction via the second rotating rod 12. The threaded rod 15 drives the moving plate 22 on it to move upward. The moving plate 22 slides along the long groove of the first semi-circular cover 17 and the second semi-circular cover 21. As the moving plate 22 moves, the torsion spring on the third rotating rod 25 is no longer under force and begins to recover its deformation. The force generated by the torsion spring recovering its deformation drives the third rotating rod 25 to rotate in the opposite direction. The rotation of the third rotating rod 25 drives the shielding net 26 to rotate and roll up. The synchronous movement of the rotation of the third rotating rod 25 and the moving plate 22 makes the rolling up of the shielding net 26 smoother. When the second cab door 3 is fully opened, the rack plate 7 stops sliding, and the first rotating rod 8, the first gear 9, and the second gear 10 stop rotating. At this time, the torsion spring has fully recovered its deformation, and the shielding net 26 is fully rolled up. Thus, the entire process of opening and closing the cab door of the electric loader is completed.

The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
