[0059] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of methods and apparatus consistent with certain aspects of the present application, as detailed in the appended claims.

[0060] The terms "first," "second," "third," "fourth," etc. (if any) in the specification and claims of the present application and in the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential sequence. It should be understood that the numbers used in this way are interchangeable where appropriate, so that the embodiments of the present application described herein can, for example, be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having," and any variations thereof, are intended to cover non-exclusive inclusions, for example, a process, method, system, product, or apparatus comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products, or apparatus.

[0061] Currently, some sunshade devices use hooks to attach to hooks or holes on the skylight to prevent the curtain from automatically retracting. However, this only allows for adjustment of the shade area to one or a few locations, depending on the number and position of the hooks, and cannot achieve hovering at any position. Other sunshade devices achieve hovering through an interference fit between a rubber ring and a guide rod. However, this fit creates high friction, resulting in an awkward sliding motion when the curtain is pulled, resulting in a poor user experience.

[0062] In response to the above-mentioned problems existing in the prior art, the present application provides a sunshade device and engineering machinery. The sunshade device provided in the present application includes a support assembly, a sunshade assembly, a sliding assembly, and an elastic assembly. By arranging the sunshade assembly on the support assembly, it is convenient to use the support assembly to fix the sunshade assembly to the engineering machinery at the skylight. The sunshade assembly has a telescopic end so that the sunshade area can be adjusted by the telescopic end. The sliding assembly is connected to the telescopic end and the sliding assembly is connected to the support assembly. Then, one end of the elastic assembly is connected to the sliding assembly and the other end of the elastic assembly is connected to the support assembly. When the sliding assembly slides relative to the support assembly, the elastic assembly drives the sliding assembly to deflect in a first direction and elastically clamps with the support assembly to restrict the sliding assembly to the current position. The sliding assembly is driven to deflect toward a side away from the first direction by an external force, releasing the elastic clamping restriction between the sliding assembly and the support assembly, and the sliding assembly and the elastic assembly are driven to slide together on the support assembly by an external force to adjust the position of the telescopic end. That is, the telescopic end can be suspended at any position through the cooperation of the sliding component and the elastic component, and it is also convenient to pull and adjust, so that flexible pulling and locking can be achieved, which improves the user experience.

[0063] The following specific embodiments are used to describe the technical solution of the present application in detail. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0064] First, refer to Figure 1-Figure 3 As shown, an embodiment of the present application provides a sunshade device, including a support assembly 100 , a sunshade assembly 200 , a sliding assembly 300 and an elastic assembly 400 .

[0065] The sunshade assembly 200 is disposed on the support assembly 100 , and the sunshade assembly 200 has a telescopic end 201 .

[0066] The sliding assembly 300 is connected to the telescopic end 201 , and the sliding assembly 300 is connected to the supporting assembly 100 .

[0067] One end of the elastic component 400 is connected to the sliding component 300 , and the other end of the elastic component 400 is connected to the supporting component 100 .

[0068] The elastic component 400 is configured to drive the sliding component 300 to deflect toward the first direction when the sliding component 300 slides relative to the supporting component 100 , and elastically clamp the sliding component 300 with the supporting component 100 to limit the sliding component 300 to the current position.

[0069] The sliding assembly 300 is driven by external force to deflect toward a side away from the first direction, thereby releasing the elastic clamping restriction between the sliding assembly 300 and the support assembly 100, and the sliding assembly 300 and the elastic assembly 400 are driven by external force to slide together on the support assembly 100 to adjust the position of the telescopic end 201.

[0070] The support assembly 100 in this embodiment is used to support the sunshade assembly 200, the sliding assembly 300, the elastic assembly 400 and other components. It can be a rod-shaped, frame-shaped, shell-shaped or other structure. The support assembly 100 can be fixedly connected to the engineering machinery at the skylight by screwing, clamping, bonding or the like to ensure that the skylight window is not blocked.

[0071] The sunshade assembly 200 in this embodiment is used for shading and has a telescopic end 201 thereon, which can adjust the size of the sunshade area by telescoping. That is, when the telescopic end 201 is retracted to the minimum position, the sunshade area is the smallest, and when the telescopic end 201 is extended to the maximum position, the sunshade area is the largest. For example, the sunshade assembly 200 can be composed of a drum and a curtain. The drum can be fixedly connected to the support assembly 100 by screwing, clamping, etc., one end of the curtain is wound on a reel, and the reel is connected to the drum via a coil spring to achieve retraction. The other end of the curtain is the telescopic end 201.

[0072] The sliding assembly 300 and the elastic assembly 400 in this embodiment cooperate to limit the free movement of the telescopic end 201. The sliding assembly 300 can be a combination of components such as a slider and a slide rod. The telescopic end 201 is connected to the support assembly 100 through the sliding assembly 300. The sliding assembly 300 and the support assembly 100 can be a large clearance fit, such as a rod and sleeve fit structure. On the one hand, the sliding assembly 300 can move on the support assembly 100 to adjust the position of the telescopic end 201. On the other hand, the sliding assembly 300 can also deflect to a certain angle, causing a jam and locking between the support assembly 100.

[0073] Among them, the elastic component 400 is used to keep the sliding component 300 and the support component 100 in a locked state in a natural state. It can be composed of components such as a spring and an elastic band. One side of the elastic component 400 is connected to the sliding component 300, and the other side forms a sliding connection with the support component 100 so as to follow the movement of the sliding component 300 and adaptively adjust the position.

[0074] Specifically, if Figure 2 As shown, the telescopic end 201 is subjected to the retracting force and moves along Figure 2 When the X-axis moves in the positive direction and drives the sliding assembly 300 to slide relative to the supporting assembly 100, the elastic assembly 400 drives the sliding assembly 300 to deflect toward the first direction, such as Figure 2 As shown in the clockwise direction, the telescopic end 201 is elastically clamped with the support assembly 100 to limit the sliding assembly 300 to the current position, thereby achieving the hovering of the telescopic end 201 at any position.

[0075] For example Figure 2 、 Figure 3 As shown, the elastic force of the elastic component 400 is overcome by external force and the sliding component 300 is driven to deflect toward the side away from the first direction, as shown in FIG. Figure 2 As shown in the counterclockwise direction, the elastic clamping restriction between the sliding component 300 and the supporting component 100 is released, and the sliding component 300 and the elastic component 400 are driven by external force to slide on the supporting component 100, such as along Figure 3 The X-axis is moved in the positive or negative direction to adjust the position of the telescopic end 201 to adjust the size of the sunshade area.

[0076] It can be understood that, compared with the existing sunshade devices that are not easy to pull or lock flexibly, the application of the sunshade device in this embodiment can suspend the telescopic end 201 at any position through the cooperation of the sliding component 300 and the elastic component 400, and is also convenient for pulling and adjusting, thereby achieving flexible pulling and locking, and improving the user experience.

[0077] Thus, the sunshade device provided in the embodiment of the present application includes a support assembly 100, a sunshade assembly 200, a sliding assembly 300, and an elastic assembly 400. By disposing the sunshade assembly 200 on the support assembly 100, the support assembly 100 facilitates the sunshade assembly 200 to be fixed to the construction machinery at the skylight. The sunshade assembly 200 has a telescopic end 201, so that the shading area can be adjusted by the telescopic end 201. The sliding assembly 300 is connected to the telescopic end 201 and then connected to the support assembly 100. Furthermore, one end of the elastic assembly 400 is connected to the sliding assembly 300, and the other end of the elastic assembly 400 is connected to the support assembly 100. When the sliding assembly 300 slides relative to the support assembly 100, the elastic assembly 400 drives the sliding assembly 300 to deflect in a first direction and elastically engages with the support assembly 100 to constrain the sliding assembly 300 in its current position. By driving the sliding assembly 300 to deflect away from the first direction through external force, the elastic clamping restriction between the sliding assembly 300 and the support assembly 100 is released, and the sliding assembly 300 and the elastic assembly 400 are then driven by external force to slide together on the support assembly 100 to adjust the position of the telescopic end 201. In other words, the sliding assembly 300 and the elastic assembly 400 cooperate to allow the telescopic end 201 to hover at any position, making it easier to pull and adjust, thereby achieving flexible pulling and locking, and improving the user experience.

[0078] In one possible design, the sliding assembly 300 includes a slider 310 , and the slider 310 includes a sliding portion 311 and an eccentric portion 312 connected to one side of the sliding portion 311 .

[0079] The support assembly 100 is provided with a sliding section 101 , the sliding portion 311 is sleeved on the sliding section 101 , and the eccentric portion 312 is connected to the elastic assembly 400 .

[0080] The sliding portion 311 is configured to elastically clamp with the sliding section 101 when the slider 310 deflects toward the first direction, and release the elastic clamping restriction with the sliding section 101 when the slider 310 deflects toward a side away from the first direction.

[0081] In one example, Figure 2 As shown, the sliding section 101 can be a slide rod, and the sliding portion 311 has a through hole 3111. There is a clearance fit between the through hole 3111 and the slide rod, that is, the slider 310 moves relative to the support assembly 100 along the Figure 2 When the slider 310 deflects in the clockwise direction to a certain angle, a jam occurs between the through hole 3111 and the slide bar, thereby achieving clamping. When the slider 310 deflects toward the side away from the first direction, the elastic clamping restriction between the through hole 3111 and the slide bar is released, and the slider 310 can move along the upper edge of the slide bar. Figure 2 Forward or reverse movement of the X axis.

[0082] In another example, not shown, the sliding section 101 may be a slot, with sliding teeth on the sliding portion 311. The teeth and slot also have a clearance fit. This means that when the slider 310 deflects clockwise relative to the support assembly 100 to a certain angle, the teeth and slot become locked, achieving a secure fit. When the slider 310 deflects away from the first direction, the elastic locking restriction between the teeth and slot is released, allowing the slider 310 to move within the slot again.

[0083] Among them, which of the above structures is adopted between the slider 310 and the support assembly 100 can be determined according to actual needs and is not excessively restricted in this embodiment.

[0084] Furthermore, in this embodiment, the sliding assembly 300 further includes an anti-slip member 320 , which is disposed on the sliding portion 311 .

[0085] The anti-slip member 320 is configured such that when the sliding portion 311 and the sliding section 101 are elastically clamped together, the sliding portion 311 contacts the sliding section 101 through the anti-slip member 320 .

[0086] Specifically, the anti-slip member 320 can be an anti-slip member such as a rubber sleeve, for example, Figure 2 As shown, the rubber sleeve is set in the through hole 3111 on the sliding part 311, and the rubber sleeve and the slide rod are also clearance-matched. In this way, when the slider 310 moves relative to the support assembly 100 along the Figure 2 When the lever is deflected clockwise to a certain angle, the rubber sleeve contacts the slide bar, increasing friction and making the lock more stable, preventing free movement. When the elastic clamping restriction between the rubber sleeve and the slide bar is released, there is no resistance between the two, making movement and adjustment easier.

[0087] Of course, the anti-slip member 320 can also be replaced by other types of anti-slip components, such as rubber pads. When the sliding portion 311 is provided with sliding teeth, the rubber pads can be provided on the sliding teeth to also increase friction. Therefore, the specific type of the anti-slip member 320 can be determined according to actual needs and is not specifically limited in this embodiment.

[0088] Furthermore, in this embodiment, the sliding assembly 300 further includes a pull rod 330 , and there are two sliders 310 . Both ends of the pull rod 330 are respectively connected to the eccentric portions 312 of the two sliders 310 .

[0089] The telescopic end 201 is wound around the pull rod 330 , and the pull rod 330 is also provided with a handle 331 .

[0090] Specifically, if Figure 2As shown, the length direction of the pull rod 330 is perpendicular to the moving direction of the slider 310. The two ends of the pull rod 330 can be respectively connected to the eccentric parts 312 of the two sliders 310 by screwing, plugging, snapping, etc., and part of the telescopic end 201 is wound on the pull rod 330. In this way, it is ensured that the telescopic end 201 can be flattened.

[0091] In addition, a handle 331 is provided at the upper middle portion of the pull rod 330. The handle 331 faces the operator, allowing the operator to hold the handle 331 to manipulate the deflection and movement of the pull rod 330 and the slider 310. The specific size of the pull rod 330 and the specific shape of the handle 331 can be determined based on actual needs and are not specifically limited in this embodiment.

[0092] In some embodiments, the elastic assembly 400 includes an elastic member 410 and a connecting member 420 , and one end of the elastic member 410 is connected to the eccentric portion 312 .

[0093] The other end of the elastic member 410 is connected to the connecting member 420 , and the connecting member 420 is sleeved on the sliding section 101 .

[0094] Specifically, if Figure 2 As shown, the elastic member 410 can be an elastic component such as a tension spring or rubber band. The connecting member 420 is used to enable the elastic member 410 to slide adaptively on the sliding section 101. The connecting member 420 can be a sliding sleeve that is mounted on the sliding section 101. One end of the elastic member 410 can be connected to the eccentric portion 312 by hooking, snapping, or other means, and the other end of the elastic member 410 can also be connected to the connecting member 420 by hooking, snapping, or other means. In this way, while the elastic member 410 elastically tensions the eccentric portion 312, the connecting member 420 can slide adaptively and adjust its position on the sliding section 101.

[0095] Of course, the connector 420 can also be replaced by other types of connecting components, such as a connecting block. When the sliding section 101 is a slide groove, the connecting block can be slidably connected to the slide groove via latches. Therefore, the specific structure of the connector 420 can be determined according to the actual sliding section 101 and is not excessively limited in this embodiment.

[0096] Furthermore, in this embodiment, one end of the elastic member 410 has a first hanging portion 411 , and the eccentric portion 312 has a second hanging portion 3121 matching the first hanging portion 411 , and the first hanging portion 411 is hung with the second hanging portion 3121 .

[0097] And / or, the other end of the elastic member 410 has a third hanging portion 412 , the connecting member 420 has a fourth hanging portion 421 matching the third hanging portion 412 , and the third hanging portion 412 is hung with the fourth hanging portion 421 .

[0098] Specifically, if Figure 2 As shown, the first hanging portion 411 and the third hanging portion 412 are both hooks, and the second hanging portion 3121 and the fourth hanging portion 421 are both hanging holes or hanging ears. This arrangement facilitates the installation and replacement of the elastic member 410, and has a simple structure and is stable and reliable.

[0099] Of course, the eccentric portion 312 and the connection member 420 and the elastic member 410 may also be replaced by other types of connection structures as long as they are easy to disassemble and assemble. This embodiment does not impose too many restrictions on this.

[0100] In some embodiments, the sunshade assembly 200 includes a roller 210 and a curtain 220 , and the roller 210 is connected to one side of the support assembly 100 .

[0101] One end of the curtain 220 is wound on the drum 210 , and the other end of the curtain 220 is the telescopic end 201 . The side of the eccentric portion 312 close to the drum 210 is connected to the elastic member 410 .

[0102] For example, Figure 1 、 Figure 2 As shown, the reel 210 can be fixedly connected to the support assembly 100 by screwing, clamping, etc. The reel 210 is a hollow structure, in which a reel and a coil spring are provided. One end of the curtain 220 is wound on the reel. The coil spring is connected to the reel and is used to drive the reel to rotate and retract the curtain 220 into the reel. The other end of the curtain 220 is the telescopic end 201.

[0103] In this way, when the telescopic end 201 is pulled by an external force to overcome the elastic force of the coil spring, the curtain 220 can be pulled out from the reel 210. When the external force is eliminated, the curtain 220 can be automatically retracted into the reel 210.

[0104] It should be noted that the elastic force of the coil spring should not be too large, so as to avoid requiring a large external force to pull the curtain 220, affecting the user experience. It is sufficient to ensure that after the external force is eliminated, the curtain 220 can be automatically rolled into the reel 210.

[0105] In some embodiments, the support assembly 100 includes two guide rods 110 , which are spaced apart from each other. There are two sliders 310 , and each guide rod 110 has a sliding section 101 .

[0106] The two sliders 310 are correspondingly disposed on the two guide rods 110 , and at least one elastic component 400 connects the sliders 310 and the adjacent guide rods 110 .

[0107] Specifically, if Figure 1 、 Figure 2As shown, the guide rods 110 are arranged side by side, and the guide rods 110 have sliding sections 101 , and two sliders 310 are correspondingly arranged on the two guide rods 110 so that the sliders 310 can be locked or slid on the guide rods 110 to ensure the stability of the telescopic end 201 in hovering.

[0108] Furthermore, an elastic assembly 400 is slidably connected to at least one of the guide rods 110, and the elastic assembly 400 is connected to a nearby slider 310 to ensure the stability of the elastic tension. Of course, the support assembly 100 can also be replaced by other types of support components that can support the sunshade assembly 200, the sliding assembly 300, and the elastic assembly 400, and do not block the sunroof. This embodiment is not too restrictive.

[0109] Furthermore, in this embodiment, the support assembly 100 further includes a mounting bracket 120 , and the mounting bracket 120 is used to connect each guide rod 110 to the engineering machinery.

[0110] For example, Figure 1 As shown, there can be four mounting brackets 120, one end of the two guide rods 110 is fixedly connected to the engineering machinery on one side of the skylight through two mounting brackets 120, and the other end of the two guide rods 110 is fixedly connected to the sunshade assembly 200, and the sunshade assembly 200 is fixedly connected to the engineering machinery on the other side of the skylight through another two mounting brackets 120, thereby achieving the fixation of the four corners of the sunshade device, which is more stable.

[0111] The specific structure, shape, quantity, etc. of the mounting bracket 120 can be determined according to actual needs and are not specifically limited in this embodiment.

[0112] In a second aspect, an embodiment of the present application further provides an engineering machinery, comprising a main body, a cab being provided on the main body, a skylight being provided in the cab, and a sunshade device provided by any of the above embodiments being provided on the skylight.

[0113] The structure of the sunshade device has been described in detail in the above embodiments and will not be described in detail here.

[0114] The above-mentioned engineering machinery can be an excavator, a crane, a loader, etc. The support assembly 100 can be fixedly connected to the engineering machinery around the skylight by screwing, clamping, bonding, etc., so that when the telescopic end 201 is telescopically moved, it can completely block the sunlight at the skylight, or be fully opened to allow the operator to view the external conditions through the skylight.

[0115] The engineering machinery provided in the embodiments of the present application is equipped with a sunshade device, including a support assembly 100, a sunshade assembly 200, a sliding assembly 300, and an elastic assembly 400. The sunshade assembly 200 is disposed on the support assembly 100, thereby facilitating the sunshade assembly 200 to be fixed to the engineering machinery at the skylight thereof using the support assembly 100. The sunshade assembly 200 has a telescopic end 201, which allows the sunshade area to be adjusted by the telescopic end 201. The sliding assembly 300 is connected to the telescopic end 201 and then connected to the support assembly 100. Furthermore, one end of the elastic assembly 400 is connected to the sliding assembly 300, and the other end of the elastic assembly 400 is connected to the support assembly 100. When the sliding assembly 300 slides relative to the support assembly 100, the elastic assembly 400 drives the sliding assembly 300 to deflect in a first direction and elastically engages with the support assembly 100 to constrain the sliding assembly 300 in its current position. By driving the sliding assembly 300 to deflect away from the first direction through external force, the elastic clamping restriction between the sliding assembly 300 and the support assembly 100 is released, and the sliding assembly 300 and the elastic assembly 400 are then driven by external force to slide together on the support assembly 100 to adjust the position of the telescopic end 201. In other words, the sliding assembly 300 and the elastic assembly 400 cooperate to allow the telescopic end 201 to hover at any position, making it easier to pull and adjust, thereby achieving flexible pulling and locking, and improving the user experience.
