[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application. Example

[0020] Reference Figures 1-4 In this embodiment, an electric sunshade for heavy-duty trucks includes: The mounting components include a first connecting seat 1 fixed to the top of the heavy truck cab, and a connecting plate 2 for mounting the drive assembly is connected to the first connecting seat 1.

[0021] A support base 10 is disposed above the first connecting base 1. One end of the support base 10 is rotatably connected to one top end of the first connecting base 1, and the other end can optionally abut against the other top end of the first connecting base 1. A drive assembly is drivenly connected to the support base 10. A second connecting base 6 is connected to the top of the support base 10. A sunshade assembly is spaced above the second connecting base 6. An extension assembly 5 is connected between the second connecting base 6 and the sunshade assembly, and the drive assembly is drivenly connected to the extension assembly 5.

[0022] In detail, the mounting components provide a stable foundation for the entire device. Its core components include a first connecting seat 1, a connecting plate 2, and a third connecting seat 13. The first connecting seats 1 are made of Q235 steel plate, stamped into four pieces. They are symmetrically fixed to pre-drilled mounting holes on the top of the heavy-duty truck cab using M16 high-strength bolts. The spacing between the four first connecting seats 1 matches the width of the cab top, forming a rectangular fixing frame. Adjacent first connecting seats 1 are welded together using connecting plates 2. The connecting plates 2 are made of alloy steel plate, and their length matches the spacing between adjacent connecting seats. After welding, the weld seams are ground with an angle grinder to ensure a smooth surface and that the connection strength meets standards.

[0023] Specifically, a third connecting seat 13 is bolted to the top of the two first connecting seats 1 near the front of the cab. The third connecting seat 13 has a U-shaped groove structure, and a rotating shaft 11 is fixedly connected between the two third connecting seats 13. The groove width is adapted to the diameter of the rotating shaft 11. The rotating shaft 11 is made of 45# round steel, and a bearing is installed on each end of the shaft that extends out of the third connecting seat 13. The outer ring of the bearing mates with the side mounting hole of the support seat 10, allowing the support seat 10 to rotate flexibly around the rotating shaft 11 with a rotational resistance torque of no more than 5 N·m.

[0024] Furthermore, the top of the first connecting seat 1, which abuts against the support seat 10, is sequentially connected from bottom to top with a rubber seat 9 and a mating block 8. The support seat 10 is made of die-cast aluminum alloy and has an overall rectangular structure. One end of it is rotatably connected to the rotating shaft 11 via a bearing, and the bottom of the other end is recessed with a circular groove for mating with the mating block 8 on the top of the first connecting seat 1. The mating block 8 is a solid rubber block, which is bonded to the top of the first connecting seat 1 with epoxy resin. The rubber seat 9 below it is made of nitrile rubber with a Shore hardness of 60, which can effectively buffer the impact force when the support seat 10 rotates to its limit position and reduce vibration and noise.

[0025] More specifically, the drive assembly includes a hydraulic cylinder 3 and a drive motor 506. The hydraulic cylinder 3 is a bidirectional telescopic single-rod hydraulic cylinder, model HOB-80×200, whose telescopic stroke is adapted to the maximum unfolding stroke of the subsequent extension assembly 5, ensuring coordinated action between the two. The fixed end of the hydraulic cylinder 3 is hinged to a pre-set lug on the connecting plate 2 via a pin, and the pin surface is chrome-plated. The telescopic end is fixed with a hinge seat 12 via a threaded connection. The hinge seat 12 is hinged to the connecting rod 7 welded to the outside of the support base 10 via a pin. The connecting rod 7 is made of round steel and requires flaw detection after welding to ensure there are no welding defects.

[0026] Furthermore, the drive motor 506 is a DC geared motor, model 60BLDC-100. The motor is fixed to one end of the second connecting seat 6 near the fifth hinge rod 505 via a motor bracket. The motor output shaft is connected to the drive end of the fifth hinge rod 505 via a coupling. The coupling is a flexible pin coupling, which can compensate for installation errors and prevent jamming during motor operation.

[0027] More specifically, the second connecting seat 6 is a welded steel plate structure, fixed to the top of the support seat 10 and fastened with M12 bolts. Both its top and bottom are machined with hinge holes for connecting the extension assembly 5. The extension assembly 5 adopts a scissor-type linkage structure, with two sets symmetrically arranged on both sides of the sunshade frame 4. Each set of linkages is made of high-strength aluminum alloy profile with a rectangular cross-section, and the hinged rods are hinged together by stainless steel pins.

[0028] Reference Figures 5-6In this embodiment, the extension component 5 includes: a first hinge rod 501, a second hinge rod 502, a third hinge rod 503, a fourth hinge rod 504, and a fifth hinge rod 505. The specific connection relationships are as follows: the fourth hinge rod 504 is fixedly connected to the side of the sunshade frame 4 by bolts, forming a rigid connection with the frame. One end of the first hinge rod 501 is connected to the top hinge hole of the second connecting seat 6 via a pin, and the other end is hinged to the bottom hinge hole of the fourth hinge rod 504. The second hinge rod 502 is arranged parallel to the fourth hinge rod 504, with one end hinged to the middle of the first hinge rod 501 and the other end hinged to the third hinge rod 503. The third hinge rod 503 is arranged parallel to the first hinge rod 501, with one end hinged to the middle of the fourth hinge rod 504 and the other end hinged to the free end of the second hinge rod 502, forming a scissor core structure. One end of the fifth hinge rod 505 is hinged to the bottom hinge hole of the second connecting seat 6, and the other end is hinged to the hinge point of the second hinge rod 502 and the third hinge rod 503, forming a complete linkage mechanism. After assembly, the sunshade frame 4 needs to be manually pushed to ensure that each hinge point rotates flexibly without any jamming.

[0029] It is worth noting that the sunshade assembly includes a sunshade 14 and a sunshade frame 4. The sunshade frame 4 is a rectangular frame structure, welded from aluminum alloy square tubing. The frame size is adapted to the sunshade 14, and its two sides are fixedly connected to the fourth hinge rod 504 of the two sets of extension components 5. The sunshade 14 is made of polycarbonate (PC) endurance board with a thickness of 3mm and a UV-resistant coating on the surface. Its projected area matches the sunlight exposure area of ​​the heavy truck cab adapted in this embodiment, achieving full coverage. The sunshade 14 is fixed to the sunshade frame 4 with self-tapping screws. After fixing, the surface of the sunshade is flat and free from warping.

[0030] The working process of the electric sunshade for heavy trucks in this embodiment is as follows: When the driver needs to use the sunshade function, pressing the "unfold" button in the cab activates the control circuit, which first connects the forward rotation circuit of the drive motor 506. The motor output shaft drives the fifth hinge rod 505 to rotate clockwise around the bottom hinge point of the second connecting seat 6. Since the free end of the fifth hinge rod 505 is connected to the hinge points of the second hinge rod 502 and the third hinge rod 503, its rotation pushes the hinge points of the second hinge rod 502 and the third hinge rod 503 outward, thereby causing the first hinge rod 501 and the fourth hinge rod 504 to move synchronously, causing the scissor-type extension assembly 5 to gradually unfold.

[0031] When the extension assembly 5 is extended to 1 / 3 of its stroke, the control circuit connects the extension circuit of the hydraulic cylinder 3 via a time-delay relay. The telescopic end of the hydraulic cylinder 3 slowly extends, pushing the hinge seat 12 and the connecting rod 7, causing the support seat 10 to rotate counterclockwise around the rotating shaft 11. During the rotation of the support seat 10, the groove at its bottom gradually separates from the docking block 8. When it rotates to a 90° angle with the top of the cab (the support seat 10 is at its maximum rotation angle), the hydraulic cylinder 3 triggers the stroke limit switch, stopping the extension. At this time, the drive motor 506 continues to run until the extension assembly 5 is fully extended, and the sunshade 14 moves to the preset sunshade position in front of the cab. The motor then triggers the stroke limit switch on the other end, stopping the rotation.

[0032] To adjust the sunshade angle, the driver can press the "Angle Adjustment" button to control the extension and retraction of the hydraulic cylinder 3 within the angle range of 0°-90° between the support base 10 and the third connecting base 13. When the hydraulic cylinder 3 extends, the support base 10 rotates counterclockwise around the pivot 11, increasing the sunshade angle; when the hydraulic cylinder 3 retracts, the support base 10 rotates clockwise, decreasing the sunshade angle. The extension and retraction of the hydraulic cylinder 3 is monitored in real time by a displacement sensor, and the signal is fed back to the control circuit to achieve precise angle adjustment with an accuracy of up to 1°, meeting the usage requirements under different lighting conditions.

[0033] When the sunshade is not needed, the driver presses the "Retract" button. The control circuit first activates the retraction circuit of hydraulic cylinder 3, causing hydraulic cylinder 3 to rotate clockwise until the groove at the bottom of support base 10 is fully engaged with docking block 8. Hydraulic cylinder 3 then triggers the travel limit switch to stop working. Subsequently, drive motor 506 activates the reverse circuit, and the output shaft drives the fifth hinge rod 505 to rotate counterclockwise, pulling the hinge points of the second hinge rod 502 and the third hinge rod 503 inward, causing the extension assembly 5 to gradually retract.

[0034] When the extension component 5 is retracted to its shortest state, the sun visor 14 forms a 15° angle with the top of the cab. At this time, the drive motor 506 triggers the travel limit switch and stops operating. After being retracted, the sun visor 14 and the top of the cab form a guide structure, reducing wind resistance. The overall height of the device is limited, so it will not affect the passage height and safety of the heavy truck.

[0035] In this embodiment, a dual-drive mode of "hydraulic cylinder + drive motor" is adopted. The drive motor 506 serves as the core power source of the extension component 5, driving the scissor linkage structure through the fifth hinge rod 505 to achieve linear extension and retraction of the sunshade 14, significantly expanding the shading range. The hydraulic cylinder 3 adjusts the shading angle by driving the support base 10 to rotate. The actions of the two are coordinated through the timing control of the control circuit to avoid interference. At the same time, the bidirectional telescopic structure of the hydraulic cylinder 3 and the telescopic stroke adapted to the extension component 5 ensure that the sunshade 14 maintains a stable shading angle in different extension states.

[0036] The installation components in this embodiment adopt a modular design. The fixing holes of the first connecting seat 1 can be adjusted according to the installation requirements of different heavy-duty truck cabs, and the length of the connecting plate 2 can also be flexibly cut to fit cabs of different widths. The size of the sunshade 14 can be customized according to the sunlight exposure area of ​​the cab to ensure the sunshade effect. This modular design allows the device to be adapted to various heavy-duty truck models, reducing production and modification costs and improving the product's versatility.
