Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, and in particular to a sunshade component and engineering machinery. Background Technology

[0002] In current construction machinery, the cab is equipped with sunshades to block sunlight. For cabs with both a front window and a sunroof, the sunshade assembly is generally designed as a spanning type to meet the sunshade needs of both. In this type, the curtain needs to span the sunroof, be redirected by a lever, and then pulled towards the front window before being fixed to a fixed point. This type of sunshade assembly, with its position spanning from the sunroof to the front window, occupies a significant amount of space. If sunshade is needed for the front window, the curtain must first be pulled across the sunroof before being fixed to the front window, resulting in a long operating distance, inflexible adjustment, and low operating comfort. Furthermore, it cannot finely adjust the shading area according to changes in the angle of sunlight at different times or under different working conditions, making it unreliable. Utility Model Content

[0003] The purpose of this utility model is to provide a sunshade component that can block windows in different areas by adjusting the position of the sunshade curtain. It has a simple structure, occupies little space, and can make more precise adjustments to the sunshade area according to the changes in the angle of light at different times or under different working conditions, making it highly practical.

[0004] To achieve this objective, the present invention adopts the following technical solution:

The first connecting part is disposed on the bracket, and the first connecting part and the second connecting part are hinged through the hinge shaft. The first connecting part can remain fixed after swinging relative to the second connecting part to the position.

[0008] The sunshade curtain includes a curtain fabric, a roller retractor, and a pull rod. The roller retractor is located at the first end of the curtain fabric and fixed to the bracket. The pull rod is located at the second end of the curtain fabric. The fixing member is used to fix the pull rod after the curtain fabric is extended.

[0009] Preferably, the fastener includes hooks, and multiple sets of hooks are spaced apart along the pull-out direction of the curtain. Each set of hooks is spaced apart along the length direction of the retractor, and the hooks are used to engage with the pull rod.

[0010] Preferably, the hook and the bracket are connected by a first fastener. The hook has a first hole and the bracket has a second hole. The first fastener passes through the first hole and the second hole to fix the hook and the bracket.

[0011] Preferably, the fastener includes a fixed part and a telescopic part, one of which is connected to the bracket and the other is connected to the pull rod. The telescopic part can extend or retract relative to the fixed part to drive the pull rod to move so that the curtain can be extended or rolled up in the retractor.

[0012] Preferably, the fixing component is a telescopic cylinder, and the fixing part and the telescopic part correspond to the cylinder body and cylinder rod of the telescopic cylinder, respectively; or,

[0013] The fixing component is an electric push rod, which includes at least two nested rods. The fixing part and the telescopic part correspond to the outermost rod and the remaining rods, respectively.

[0014] Preferably, the first connecting part is connected to the bracket by a second fastener. The first connecting part has a third hole, and the bracket has a fourth hole. The second fastener passes through the third hole and the fourth hole to fix the first connecting part and the bracket.

[0016] Preferably, the swing range of the first connecting part relative to the second connecting part is 0°-180°.

[0017] This utility model also provides an engineering machinery, including the above-mentioned sunshade component. The sunshade component is installed in the cab of the engineering machinery. By adjusting the position of the sunshade, the front window or the sunroof can be selectively shaded, which is highly practical.

[0018] An engineering machine, comprising:

[0019] The driver's cab has a front window and a sunroof;

[0020] As described in any of the above-mentioned sunshade components, the second connecting portion is fixed to the top of the cab, and the first connecting portion swings relative to the second connecting portion to allow the sunshade curtain to block the front window or the sunroof.

[0021] Preferably, the second connecting part is connected to the cab by a third fastener. The second connecting part has a fifth hole, and the cab has a sixth hole. The third fastener passes through the fifth hole and the sixth hole to fix the second connecting part to the cab.

[0022] Beneficial effects:

[0023] The sunshade assembly provided by this utility model, when applied to a cab with both a front window and a sunroof, has a bracket connected to the top of the cab via a damping hinge. The first connecting part swings relative to the second connecting part around the hinge axis, effectively adjusting the position of the sunshade curtain, allowing it to swing between the sunroof and the sunroof to adjust its position. When sunlight directly hits the sunroof, it is necessary to shade the sunroof while avoiding blocking the front window to maintain a certain level of brightness in the cab without needing additional lighting. In this case, adjusting the angle between the first and second connecting parts and swinging the bracket adjusts the sunshade curtain to the sunroof, providing sunshade only to the sunroof. Similarly, when sunlight directly hits the front window, it is necessary to shade the front window while avoiding blocking the sunroof to maintain a certain level of brightness in the cab without needing additional lighting. In this case, adjusting the angle between the first and second connecting parts and swinging the bracket adjusts the sunshade curtain to the front window, providing sunshade only to the front window. Once the sunshade is adjusted to its proper position, pulling the lever extends the curtain relative to the roller retractor. The lever is then secured by fasteners on the bracket to maintain the extended curtain position, thus achieving the sunshade function. Compared to traditional spanning sunshade components, this sunshade assembly has a simpler structure, occupies less space, and offers more flexible and convenient adjustment. It allows for more precise adjustment of the shading area based on changes in the angle of sunlight at different times or under different working conditions, making it highly practical.

[0024] The engineering machinery provided by this utility model includes the aforementioned sunshade component, as well as a cab that has both a front window and a sunroof. It has a simple structure, occupies little space, and is more flexible and convenient to adjust. It can make more precise adjustments to the shading area of ​​the sunshade component according to the changes in the angle of light at different times or under different working conditions, making it highly practical.

[0042] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0043] This utility model provides an engineering machine, which includes a cab with a front window and a sunroof. The engineering machine also includes a sunshade assembly. (See reference...) Figures 1 to 8As shown, the sunshade assembly includes a bracket 1, a damping hinge 2, and a sunshade curtain 3. The bracket 1 is equipped with a fixing member; the damping hinge 2 includes a first connecting part 21, a second connecting part 22, and a hinge shaft (not shown). The first connecting part 21 is located on the bracket 1, and the first connecting part 21 and the second connecting part 22 are hinged together via the hinge shaft. The first connecting part 21 remains fixed after swinging relative to the second connecting part 22 to its designated position. The sunshade curtain 3 includes a curtain fabric 31, a retractor 32, and a pull rod 33. The retractor 32 is located at the first end of the curtain fabric 31 and fixed to the bracket 1. The pull rod 33 is located at the second end of the curtain fabric 31. The fixing member is used to secure the pull rod 33 after the curtain fabric 31 is pulled out. The second connecting part 22 is fixed to the top of the cab. The swinging of the first connecting part 21 relative to the second connecting part 22 allows the sunshade curtain 3 to cover the front window or sunroof.

[0044] In this embodiment, when the sunshade assembly is applied to a cab that has both a front window and a sunroof, the bracket 1 is connected to the top of the cab via a damping hinge 2. The first connecting part 21 swings relative to the second connecting part 22 around the hinge axis, which is equivalent to adjusting the position of the sunshade 3, allowing the sunshade 3 to swing between the sunroof and the sunroof to adjust its position. When sunlight shines directly on the sunroof, it is necessary to shade the sunroof on the one hand, but on the other hand, it is not desirable to block the front window so that the cab can maintain a certain level of brightness without the need for additional lighting. At this time, the angle between the first connecting part 21 and the second connecting part 22 is adjusted, and the bracket 1 is swung to adjust the sunshade 3 to the sunroof, shading the sunroof separately. Figure 5 As shown; when sunlight shines directly on the windshield, it is necessary to shade the windshield on the one hand, but on the other hand, it is not desirable to block the sunroof so that the cabin can maintain a certain level of brightness without the need for additional lighting. At this time, the angle between the first connecting part 21 and the second connecting part 22 is adjusted, and the swing bracket 1 is swung to adjust the sunshade 3 to the windshield, shading the windshield separately. Figure 6 As shown. After the sunshade curtain 3 is adjusted into place, the curtain 31 is pulled out relative to the retractor 32 by pulling the lever 33. Then, the lever 33 is fixed by the fixing parts on the bracket 1 to keep the curtain 31 in the pulled-out state, thus achieving the sunshade function. Compared with the traditional spanning sunshade component, this sunshade component has a simpler structure, occupies less space, and is more flexible and convenient to adjust. It can make more precise adjustments to the shading area of ​​the sunshade component according to the changes in the light angle at different times or under different working conditions, making it highly practical.

[0045] In this embodiment, the fixing component includes hooks 41. Multiple sets of hooks 41 are spaced apart along the pull-out direction of the curtain 31. Each set of hooks 41 has multiple hooks spaced apart along the length of the retractor 32. The hooks 41 are used to engage with the pull rod 33. Specifically, different sets of hooks 41 correspond to different fixing points on the pull rod 33, which also correspond to different pull-out positions of the curtain 31. When the curtain 31 is pulled out to the target position, the pull rod 33 is engaged with the corresponding set of hooks 41, and the curtain 31 is held in the corresponding pull-out position by fixing the pull rod 33. Different pull-out positions of the curtain 31 correspond to different shading areas, thus allowing for more precise adjustment of the shading area of ​​the shading component according to changes in the light angle at different times or under different working conditions.

[0046] For example, in this embodiment, the hooks 41 are provided in three sets, and each set of hooks 41 has two hooks 41.

[0047] Specifically, the hook 41 and the bracket 1 are connected by a first fastener 51. The hook 41 has a first hole, and the bracket 1 has a second hole 11. The first fastener 51 passes through the first hole and the second hole 11 to fix the hook 41 and the bracket 1. Specifically, the first fastener 51 can be a first threaded connector, which includes a first bolt and a first nut. The first bolt passes through the first hole and the second hole 11 and is threadedly connected to the first nut. The first threaded connector can also be a first screw, with the corresponding second hole 11 being a threaded hole, and the first screw passing through the first hole and the second hole 11 and being threadedly connected.

[0048] In some alternative embodiments, the fastener includes a fixed part 42 and a telescopic part 43. One of the fixed part 42 and the telescopic part 43 is connected to the bracket 1, and the other is connected to the pull rod 33. The telescopic part 43 extends and retracts relative to the fixed part 42, which drives the pull rod 33 to move, so that the curtain 31 is pulled out or rolled up in the retractor 32. By setting the fixed part 42 and the telescopic part 43, the extension and retraction of the telescopic part 43 relative to the fixed part 42 controls the position of the pull rod 33, thereby cooperating with the retractor 32 to realize the pulling and retracting action of the curtain 31.

[0049] For example, refer to Figure 7 As shown, the fixing component is a telescopic cylinder, with the fixing part 42 and the telescopic part 43 corresponding to the cylinder body and cylinder rod of the telescopic cylinder, respectively. Specifically, the cylinder rod of the telescopic cylinder extends outward relative to the cylinder body, which can control the pull rod 33 to move away from the retractor 32, thereby pulling out the curtain 31. When the curtain 31 is pulled out to the target position, the cylinder rod stops extending outward, and the pull rod 33 also remains stationary, thereby holding the curtain 31 at the corresponding pulled-out position.

[0050] For example, refer to Figure 8As shown, the fixing component is an electric actuator, which includes at least two nested rods. The fixing part 42 and the telescopic part 43 correspond to the outermost rod and the remaining rods, respectively. The outermost rod... Figure 8 The rightmost rod in the middle, the rest of the rods are... Figure 8 The two rods on the left side correspond to the middle rod. Specifically, the two rods on the left side of the electric push rod extend outward, which can control the pull rod 33 to move away from the retractor 32, thereby pulling out the curtain 31. When the curtain 31 is pulled out to the target position, the rods stop extending outward, and the pull rod 33 also remains stationary, thereby holding the curtain 31 at the corresponding pulled-out position.

[0051] The above settings enable automated control of the curtain 31 being pulled outward, further reducing manpower requirements.

[0052] In this embodiment, reference continues to be made to... Figures 1 to 6 As shown, the first connecting part 21 is connected to the bracket 1 via a second fastener 52. The first connecting part 21 has a third hole, and the bracket 1 has a fourth hole 12. The second fastener 52 passes through the third hole and the fourth hole 12 to fix the first connecting part 21 and the bracket 1. Specifically, the second fastener 52 can be a second screw, which includes a second bolt and a second nut. The second bolt passes through the third hole and the fourth hole 12 and is threadedly connected to the second nut. The second screw can also be a second screw, with the corresponding fourth hole 12 being a threaded hole. The second screw passes through the third hole and the fourth hole 12 and is threadedly connected to the second screw.

[0053] In this embodiment, a handle 331 is provided on the lever 33. The handle 331 makes it convenient and effortless for the driver to pull the lever 33.

[0054] In this embodiment, the swing range of the first connecting part 21 relative to the second connecting part 22 is 0°-180°. This setting effectively ensures the angle adjustment range of the sunshade 3, thereby adapting to the different angle requirements between the sunroof and the front window in the driver's cab, and is applicable when the angle between the sunroof and the front window is 90°, 100°, and 120°.

[0055] In this embodiment, the second connecting part 22 is connected to the driver's cab via a third fastener 53. The second connecting part 22 has a fifth hole, and the driver's cab has a sixth hole. The third fastener 53 passes through the fifth and sixth holes to fix the second connecting part 22 to the driver's cab. Specifically, the third fastener 53 can be a third screw connector, which includes a third bolt and a third nut. The third bolt passes through the fifth and sixth holes and is threadedly connected to the third nut. The third screw connector can also be a third screw, with the corresponding sixth hole being a threaded hole. The third screw passes through the fifth and sixth holes and is threadedly connected to the sixth hole.

[0056] In this embodiment, the retractor 32 and the bracket 1 are connected by a fourth fastener 54. The retractor 32 has a seventh hole 321, and the bracket 1 has an eighth hole 13. The fourth fastener 54 passes through the seventh hole 321 and the eighth hole 13 to fix the retractor 32 and the bracket 1. Specifically, the fourth fastener 54 can be a fourth screw connector, which includes a fourth bolt and a fourth nut. The fourth bolt passes through the seventh hole 321 and the eighth hole 13 and is threadedly connected to the fourth nut. The fourth screw connector can also be a fourth screw, with the corresponding eighth hole 13 being a threaded hole. The fourth screw passes through the seventh hole 321 and the eighth hole 13 and is threadedly connected to the eighth hole 13.
