Description

Technical Field

[0001] This utility model belongs to the technical field of excavator components, specifically relating to a folding sunshade for an excavator cab. Background Technology

[0002] During excavator outdoor operations, the cab is constantly exposed to sunlight, causing a rapid increase in temperature inside the cab, severely impacting the operator's comfort and work efficiency. Traditional excavator sunshades are mostly fixed structures that cannot be folded and stored, not only taking up space but also being prone to collisions and damage when transporting, hoisting, or passing through narrow areas. Furthermore, fixed sunshades cannot flexibly adjust the shading range according to the angle of sunlight, making it difficult to effectively block sunlight at different times of day, such as early morning, late afternoon, or midday.

[0003] Therefore, there is an urgent need to provide a folding sunshade for excavator cabs to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a folding sunshade for excavator cabs to solve the problems of large space occupation and poor adaptability of existing sunshade facilities.

[0005] To solve the above-mentioned technical problems, this utility model provides a folding sunshade for an excavator cab, comprising: a mounting plate, a long groove on the mounting plate, a pin in the long groove, a first sleeve rod at both ends of the pin rod, a first telescopic rod on the first sleeve rod, a second sleeve rod on the first telescopic rod, a second telescopic rod on the second sleeve rod, a flipping hinge between the first telescopic rod and the second sleeve rod, a first sunshade cloth between the two first sleeve rods, and a second sunshade cloth between the two second sleeve rods.

[0006] As further explained, the four corners of the first sunshade cloth are respectively installed at the bottom ends of the two first sleeve rods and the top ends of the two first telescopic rods, and the four corners of the second sunshade cloth are respectively installed at the bottom ends of the two second sleeve rods and the top ends of the two second telescopic rods.

[0007] As further explained, the length of the first sunshade cloth is equal to the length of the first set of poles plus the length of the first telescopic pole, and the length of the second sunshade cloth is equal to the length of the second set of poles plus the length of the second telescopic pole.

[0008] As further explained, the first telescopic rod is rotatably connected to the second sleeve rod via a flip hinge, and the first sleeve rod rotates within a limited range in the long groove via a pin.

[0009] As further explained, the mounting plate has threaded holes at all four corners.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. The first set of rods rotates within a long slot via a pin, coordinating with the telescopic design of the first telescopic rod, the second set of rods, and the second telescopic rod, and further folded using a flip hinge. When the sunshade is not in use, it can be folded up close to the mounting plate. Compared to fixed sunshade facilities, it occupies approximately 80% less space after folding, effectively solving the problem of collision damage caused by excessive size during transportation and hoisting, while also facilitating the passage of excavators through narrow areas.

[0012] 2. The first set of poles can rotate within a limited range within the long slot. The first telescopic pole and the second set of poles are rotatably connected via a flip hinge, allowing the sunshade to flexibly adjust the tilt angle and coverage area of ​​the first and second sunshade fabrics according to the sun's altitude and the angle of sunlight. Whether it's oblique sunlight in the morning or evening, or direct sunlight at midday, it can accurately block sunlight. Compared to traditional fixed sunshade facilities, the effective shading area is increased by approximately 60%, reducing the temperature inside the driver's cab and improving driver comfort and work efficiency.

[0013] 3. The four corners of the sunshade cloth are fixed to the top of the sleeve pole and the telescopic pole respectively, and the length of the sunshade cloth matches the combined length of the corresponding sleeve pole and telescopic pole to ensure that the sunshade cloth is taut and flat, and to avoid damage due to looseness.

[0014] 4. The first and second sunshade fabrics form a double-layer sunshade structure, which, compared to a single-layer sunshade, can effectively block more solar radiation heat and further reduce the temperature inside the driver's cabin. At the same time, the double-layer structure can also buffer the impact of wind and rain to a certain extent, improving the protective performance of the sunshade.

[0015] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objectives and other advantages of this invention are realized and obtained through the structures particularly pointed out in the description and the accompanying drawings.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figure 1-2 A folding sunshade for an excavator cab includes: a mounting plate 1, a long groove 2 on the mounting plate 1, a pin 3 within the long groove 2, first sleeve rods 4 at both ends of the pin 3, a first telescopic rod 5 on the first sleeve rod 4, a second sleeve rod 6 on the first telescopic rod 5, a second telescopic rod 7 on the second sleeve rod 6, a flip hinge 10 between the first telescopic rod 5 and the second sleeve rod 6, a first sunshade cloth 8 between the two first sleeve rods 4, and a second sunshade cloth 9 between the two second sleeve rods 6. The long groove 2 on the mounting plate 1 provides a rotation track for the pin 3, allowing the first sleeve rods 4 to swing along the long groove 2; the first sleeve rods 4 and the first telescopic rods 5, and the second sleeve rods 6 and the second telescopic rods 7 form a telescopic structure, with the length adjusted by nested sliding; the flip hinge 10 allows the first telescopic rods 5 and the second sleeve rods 6 to rotate relative to each other. When unfolded, the telescopic and rotating structures work together to support the first sunshade cloth 8 and the second sunshade cloth 9. When the sunshade is not in use, it can be folded up and folded up to fit snugly against the mounting plate 1. Compared with fixed sunshade facilities, it occupies about 80% less space after being stored, effectively solving the problem of collision damage caused by excessive size during transportation and hoisting, while also making it easier for excavators to pass through narrow areas.

[0024] like Figure 1-2 As shown, the four corners of the first sunshade cloth 8 are respectively installed at the bottom ends of the two first sleeve rods 4 and the top ends of the two first telescopic rods 5, and the four corners of the second sunshade cloth 9 are respectively installed at the bottom ends of the two second sleeve rods 6 and the top ends of the two second telescopic rods 7. This installation method allows the sunshade cloth to fit tightly against the supporting structure, forming a complete sunshade surface when unfolded, effectively blocking sunlight; when folded, it can be stored together with the supporting structure without taking up extra space.

[0025] like Figure 1-2 As shown, the length of the first shade cloth 8 is equal to the length of the first sleeve pole 4 plus the length of the first telescopic pole 5, and the length of the second shade cloth 9 is equal to the length of the second sleeve pole 6 plus the length of the second telescopic pole 7. This design ensures that the shade cloth is just taut when the telescopic pole is fully extended, avoiding insufficient coverage due to being too short or wrinkles and accumulation due to being too long, thus improving the practicality and reliability of the awning.

[0026] like Figure 1-2 As shown, the first telescopic rod 5 is rotatably connected to the second sleeve rod 6 via a flip hinge 10, and the first sleeve rod 4 rotates within a limited range in the long groove 2 via a pin 3. The first telescopic rod 5 and the second sleeve rod 6 can rotate 180° via the flip hinge 10, which can adjust the angle between the upper and lower layers of sunshade cloth; the first sleeve rod 4 swings within the long groove 2 via the pin 3 to adjust the horizontal tilt angle of the sunshade, making the folding and unfolding operation of the sunshade more flexible and convenient, and allowing the driver to easily adjust the state of the sunshade according to actual needs.

[0027] like Figure 1-2 As shown, the mounting plate 1 has threaded holes 11 at each of its four corners. These threaded holes 11 are used to install the sunshade onto the excavator cab, and the mounting plate is fixed in the appropriate position on the cab using bolts or other fasteners. This installation method also facilitates the disassembly and replacement of the sunshade, making maintenance and repair easier.
