[0034] The following is combined with Figures 1-6 to describe the overhead guard of the present utility model.

[0035] An embodiment of the first aspect of the present utility model provides an overhead guard, as Figure 1 and Figure 2 shown. The overhead guard 100 includes an overhead guard frame 110 and a shielding assembly 120 disposed on the overhead guard frame 110.

[0036] As Figure 3 and Figure 5 shown, the overhead guard frame 110 includes two brackets 111 disposed opposite to each other. Guide members 112 are provided on the opposite side walls of the two brackets 111. The guide member 112 includes a first guide portion 1121 provided on the top of the bracket 111 and a second guide portion 1122 provided on the side of the bracket 111. The first guide portion 1121 and the second guide portion 1122 are in communication.

[0037] The shielding assembly 120 includes a driving member 121, a rotating member 122, and a shielding member 123. The driving member 121 is disposed on the top of the bracket 111. The rotating member 122 is rotatably disposed between the two brackets 111, and the rotating member 122 is connected to the output of the driving member 121. The first end of the shielding member 123 is wound around the rotating member 122, and the second end of the shielding member 123 is clamped in the guide member 112 of the two brackets 111.

[0038] It can be understood that the lower part of the overhead protection frame 110 is connected to the vehicle body 200 of the working machine. A cab is formed between the overhead protection frame 110 and the vehicle body 200. The overhead protection frame 110 includes two brackets 111 arranged oppositely. Guide members 112 are provided on the opposite side walls of the brackets 111, and the guide members 112 are arranged at the top and side parts of the brackets 111.

[0039] A shielding assembly 120 is provided at the top of the overhead protection frame 110. One end of the shielding assembly 120 is wound around a rotating member 122, and the second end of the shielding member 123 is clamped in the guide members 112 of the two brackets 111. The driving member 121 drives the rotating member 122 to rotate, so that the shielding member 123 is wound or extended from the rotating member 122.

[0040] When operating in an unsafe environment such as rainy days or strong sunlight, the driving member 121 drives the rotating member 122 to rotate, so that the shielding member 123 extends. Under the guiding action of the guide member 112, the shielding member 123 extends from the top of the overhead protection frame 110 along the first guiding portion 1121 at the top of the bracket 111; and under the continuous action of the driving member 121, the shielding member 123 continues to extend from the side of the overhead protection frame 110 along the second guiding portion 1122 at the side of the bracket 111, so as to realize the shielding of the upper part and the side part of the cab, and avoid foreign objects such as rainwater and the sun that affect the operation safety of the driver from entering the cab, thereby improving the operation safety of the driver.

[0041] When operating in a safe environment such as indoors or weak sunlight, the driving member 121 drives the rotating member 122 to rotate in the reverse direction to wind the shielding member 123 on the rotating member 122 to ensure the best vision of the driver.

[0042] The overhead protection frame 100 provided by the embodiment of the present utility model is provided with a shielding assembly 120 at the top of the overhead protection frame 110. The driving member 121 drives the shielding member 123 to wind or extend, and the guide members 112 at the top and side parts of the overhead protection frame 110 provide the guiding action for the winding or extension of the shielding member 123. Thus, when operating in an unsafe environment, the shielding member 123 extends from the top and side parts of the cab to improve the operation safety of the driver; while when operating in a safe environment, the shielding member 123 is wound on the top of the overhead protection frame 110 to ensure the best vision of the driver.

[0043] In an embodiment of the present utility model, as Figure 2 and Figure 4 shown, the two brackets 111 are arranged oppositely in the left - right direction, and the second guiding portion 1122 is provided at the front side part of the bracket 111.

[0044] It should be noted that the working machine includes a vehicle body 200 and a roof guard frame 110 provided on the vehicle body 200. A cab is formed between the roof guard frame 110 and the vehicle body 200. A driver is provided in the cab. The direction the driver faces is the front side, the direction the driver turns his back to is the rear side, the left side of the driver is the left side, and the right side of the driver is the right side.

[0045] Optionally, the driving member 121 and the rotating member 122 are provided at the rear end of the top of the bracket 111. When operating in an unsafe environment such as in rainy weather, the driving member 121 drives the rotating member 122 to rotate so that the shielding member 123 extends out to shield the rain above and in front of the cab.

[0046] Exemplarily, the driving member 121 is a motor, and the rotating member 122 is a drum. The drum is rotatably supported at the rear end of the top of the two brackets 111.

[0047] In an embodiment of the present utility model, as Figure 5 shown, the first guiding portion 1121 is a groove formed in the top of the bracket 111, and the second guiding portion 1122 is a groove formed in the front portion of the bracket 111. The second end of the shielding member 123 is clamped in the grooves of the two brackets 111, and under the action of the driving member 121, the shielding member 123 can move along the groove to realize the winding or extension of the shielding member 123.

[0048] Furthermore, the second end of the shielding member 123 has a first connecting portion (not shown in the figure), and the first connecting portion is used to fix the position of the shielding member 123.

[0049] It can be understood that when the shielding member 123 extends out of the side portion of the cab, the first connecting portion at the second end of the shielding member 123 is used to fix the shielding member 123.

[0050] Optionally, a connecting plate is provided between the lower parts of the front sides of the two brackets 111, and a second connecting portion matching the first connecting portion is provided on the connecting plate. The first connecting portion can adopt other connecting structures such as a hook or a magnetic attracting member, etc.; after the shielding member 123 extends out of the side portion of the cab and reaches the in-place state, the first connecting portion at the lower end of the shielding member 123 is connected to the second connecting portion to realize the fixation of the shielding member 123 on the bracket 111. It should be noted here that the second connecting portion can also be provided on the vehicle body 200. After the shielding member 123 extends out and reaches the in-place state, the first connecting portion at the lower end of the shielding member 123 is connected to the second connecting portion of the vehicle body 200 to realize the fixation of the shielding member 123 on the vehicle body 200.

[0051] In an embodiment of the present utility model, the height of the first guiding portion 1121 gradually decreases from the end far away from the second guiding portion 1122 to the end close to the second guiding portion 1122.

[0052] It can be understood that when it is rainy, the shielding member 123 extends out of the top and sides of the cab. The height of the first guiding portion 1121 decreases sequentially from the rear to the front, so that the shielding member 123 on the top of the cab is arranged obliquely from the rear to the front, facilitating the rapid drainage of rainwater on the shielding member 123 on the top of the cab from the rear to the front and preventing rainwater from entering the cab.

[0053] It should be noted that the height of the first guiding portion 1121 can also gradually increase from the end far away from the second guiding portion 1122 to the end close to the second guiding portion 1122, and a water guiding member is arranged at the rear end of the top of the bracket 111. Rainwater on the shielding member 123 on the top of the cab is discharged from the rear to the front and through the water guiding member. The water guiding member can be a water guiding groove opened on the bracket 111.

[0054] In another embodiment of the present utility model, the height of the first guiding portion 1121 of one of the brackets 111 is higher than the height of the first guiding portion 1121 of the other bracket 111.

[0055] It can be understood that when it is rainy, the shielding member 123 extends out of the top and sides of the cab. The height of the first guiding portion 1121 of one of the brackets 111 is higher than the height of the first guiding portion 1121 of the other bracket 111, so that the shielding member 123 on the top of the cab is arranged obliquely from left to right, facilitating the rapid drainage of rainwater on the shielding member 123 on the top of the cab and preventing rainwater from entering the cab.

[0056] Optionally, the height of the first guiding portion 1121 of the left bracket 111 is higher than the height of the first guiding portion 1121 of the right bracket 111. When the shielding member 123 extends out, the shielding member 123 on the top of the cab inclines to the right. Here it should be noted that the working machine is, for example, a forklift. According to the design of existing forklifts, the driver's seat is arranged on the left side. Therefore, inclining to the right means inclining to the position away from the driver. Such a structure can prevent rainwater from entering the cab and reduce the impact of rainwater on the driver.

[0057] Furthermore, the top ends of the rear parts of the two brackets 111 are also provided with the above-mentioned shielding assembly 120. Correspondingly, third guiding portions are arranged on the opposite side walls of the rear parts of the two brackets 111. When operating in an unsafe environment such as rainy days, the driving member 121 of the shielding assembly 120 drives the rotating member 122 to rotate to make the shielding member 123 extend out to shield the rainwater behind the cab; and when operating in a safe environment, the shielding member 123 at the rear part of the bracket 111 can be retracted onto the corresponding reel.

[0058] In a preferred embodiment of the present utility model, as Figure 4 shown, the overhead guard frame 110 further includes a top frame 113 arranged on the tops of the two brackets 111.

[0059] It can be understood that the top frame 113 is connected between the two brackets 111 to improve the overall stability of the overhead protection frame 110; and the top frame 113 supports the shielding member 123 extended from the rotating member 122.

[0060] In an embodiment of the present utility model, as Figure 3 and Figure 6 shown, the shielding member 123 includes a plurality of shielding plates 1231, and adjacent two shielding plates 1231 are connected by a flexible member.

[0061] It can be understood that the shielding member 123 has a certain flexibility to be wound around the rotating member 122. At the same time, the shielding member 123 also has a certain strength to shield foreign objects such as rainwater that affect the driver's operation safety. In this embodiment, the shielding member 123 includes a plurality of shielding plates 1231 arranged side by side, the shielding plates 1231 are arranged in the left - right direction, and adjacent two shielding plates 1231 are connected by a flexible member. The shielding plates 1231 are in the shape of long strip plates, so that the shielding plates 1231 with a smaller width dimension are convenient to be wound around the rotating member 122, and the shielding plates 1231 are connected by a flexible member. When the shielding member 123 extends out, adjacent two shielding plates 1231 abut against each other, thereby improving the connection strength after the shielding member 123 extends out and being able to effectively shield foreign objects such as rainwater.

[0062] In an embodiment of the present utility model, the shielding plate 1231 includes, but is not limited to, a transparent plastic plate and a transparent soft glass plate. The shielding plate 1231 can also be other transparent materials with a certain strength in the form of a plate structure, which can not only be wound around the rotating member 122, but also shield foreign objects such as rainwater and the sun after extending from the rotating member 122.

[0063] Furthermore, the surface of the shielding member 123 has a light - shielding layer. When the shielding member 123 extends out of the top and front of the overhead protection frame 110, the sun - shading effect is improved.

[0064] Of course, the surface of the shielding member 123 can also have a waterproof layer to prevent rainwater from falling into the cab through the extended shielding member 123. Preferably, the surface of the shielding member 123 has both a light - shielding layer and a waterproof layer at the same time; or the surface of the shielding member 123 has a composite layer, and this composite layer has both a light - shielding function and a waterproof function.

[0065] The shielding component 120 of the present utility model can include three states. The first state is the semi-expanded state. According to the change of the light direction, the shielding member 123 extends out of the top of the roof frame 110. The driver can appropriately adjust the semi-expanded length to shield the driver's head, avoiding long-term exposure of the driver's head to the sun when the driver is working outdoors. The second state is the fully-expanded state. The shielding member 123 extends out of the top and sides of the roof frame 110 to prevent rainwater from entering the cab and improve the operation safety of the driver. The third state is the retracted state. In the indoor environment or in the weather with weak light, the shielding member 123 is retracted onto the rotating member 122.

[0066] An embodiment of the second aspect of the present utility model provides a working machine, such as Figure 1 shown. The working machine includes a vehicle body 200 and the roof guard 100 provided in any of the above embodiments. The lower part of the roof frame 110 of the roof guard 100 is connected to the vehicle body 200. A cab is formed between the roof frame 110 and the vehicle body 200, and the driver is arranged in the cab.

[0067] In the embodiments of the present utility model, the types of the working machines are not limited. For example, the working machine can be a forklift, an excavator, a crane, a loader, etc. In other words, as long as the working machine can use the roof guard 100 in the present utility model.

[0068] For the working machine provided by the embodiments of the present utility model, by arranging the shielding component 120 on the top of the roof frame 110, the driving member 121 drives the shielding member 123 to retract or extend, and the guiding components 112 on the top and sides of the roof frame 110 provide the guiding function for the retraction or extension of the shielding member 123. Thus, when working in an unsafe environment, the shielding member 123 extends out of the top and sides of the cab to improve the operation safety of the driver; while when working in a safe environment, the shielding member 123 is retracted onto the top of the roof frame 110 to ensure the best vision of the driver.

[0069] Furthermore, a counterweight 300 is arranged on the vehicle body 200. The rear bottom of the bracket 111 is connected to the counterweight 300, which can be realized by bolts.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit them; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
