Description

Technical Field

[0001] The utility model relates to the technical field of loader hoods, in particular to a rear-flip hood for a loader. Background Art

[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] As an important engineering machinery, loaders play an indispensable role in construction and mining. As a key component of the loader, the design and performance of the loader hood have a direct impact on the overall performance, service life and operational safety of the loader. The hood generally includes a left side panel, a right side panel, a top panel and a rear windshield panel. The hoods currently used on loaders are generally three-stage opening hoods (the left and right side panels open from the side, and the rear windshield opens backwards).

[0004] The inventors have found that the existing three-stage opening type hood has the following problems:

[0005] (1) When assembly and disassembly are required, the left and right side panels of the hood can only be opened from the side, and the rear window can be opened backwards, resulting in limited maintenance space and inconvenience in maintenance.

[0006] (2) Poor sealing: If there is water on the upper side of the left and right side panels of the hood during opening and closing, it will flow through the gaps into the components under the hood, the battery, and the high-voltage wiring harness connector, seriously affecting the service life of the components under the hood and the safety of the entire vehicle.

[0007] (3) Easily affected by external factors such as weather and temperature: The left and right side panels of the hood need to rely on gas springs to assist in opening. However, the value of the gas spring varies greatly due to the influence of temperature. In winter, when the temperature is low, it is difficult for the gas spring to push the door to the limit position. Utility Model Content

[0008] The utility model aims to provide a rear-flip hood for a loader, comprising a hood body, an electric push rod and a pair of fixed side panels; the hood body is an integral structure of left and right side panels, a top panel and a rear windshield panel;

[0009] The front end of the electric push rod is hinged to the lower right-angle inner edge of the left side plate of the hood body, and the rear end of the electric push rod is connected to the electric push rod mounting seat. The electric push rod is a telescopic structure. During the telescopic process, the electric push rod can drive the hood body to rise and fall, thereby realizing the overall backward flipping of the hood body.

[0010] As a further technical solution, the electric push rod mounting seat is fixed on the loader frame base to provide support for the electric push rod;

[0011] The rear-flip hood of the loader provided by the utility model further comprises a motor hood, which is arranged on the inner side of the left side plate of the hood body and adjacent to the front end of the electric push rod.

[0012] As a further technical solution, a motor is installed inside the motor cover, and when the motor is running, it drives the electric push rod to provide power for the electric push rod.

[0013] As a further technical solution, a flip hinge is provided at the middle position of the bottom of the rear windshield plate, and the flip hinge hinges the rear windshield plate to the loader frame base.

[0014] As a further technical solution, a pair of fixed side panels are completely identical in shape and size, both of which are approximately trapezoidal in shape, and coincide with the left and right side panels of the hood body.

[0015] As a further technical solution, a first fixing strip is provided at the upper end of the fixed side panel, and a threaded hole is opened above the first fixing strip. The position and size of the threaded hole are consistent with the left and right side panels of the hood body. The hood body can be fixed to the fixed side panel by fixing bolts.

[0016] As a further technical solution, a second fixing strip and a plurality of protrusions and grooves are provided below the fixed side plate.

[0017] As a further technical solution, one end of the second fixing strip is fixed to the sharp-angled outer edge of the lower left side panel by bolts, and the other end is fixed to the frame base; at the same time, a plurality of protrusions and grooves under the fixed side panel correspond to the grooves and protrusions designed on the frame base, so that the fixed side panel is firmly fixed to the frame base.

[0018] Beneficial effects of one or more of the above technical solutions:

[0019] (1) The utility model configures the entire loader hood body as an integral structure with left and right side panels, a top panel and a rear windshield panel. When the hood needs to be opened, the electric push rod can be controlled to extend and retract to drive the hood to rise and fall, thereby realizing the overall rearward flip of the hood. At this time, all components on the frame can be exposed. Even when disassembling large parts, there is no need to remove the hood, which provides more space for maintenance and is convenient to operate.

[0020] (2) At the same time, since the utility model configures the entire loader hood body as an integrated structure with left and right side panels, top panel and rear windshield panel, there are no longer gaps at the connections between the left and right side panels, top panel and rear windshield panel of the hood, and they no longer need to be opened separately, so the sealing is better, and the components, batteries and high-voltage wiring harnesses under the hood are better protected, thereby improving the safety of the entire vehicle.

[0021] (3) The utility model realizes the rearward flipping and position restoration of the hood by controlling the extension and retraction of the electric push rod. Compared with the existing gas spring opening method, the hood is no longer affected by uncontrollable factors such as weather and temperature, and the hood has stronger stability.

DETAILED DESCRIPTION

[0027] The specific implementation of this embodiment is described below in conjunction with the accompanying drawings.

[0028] like Figure 1 As shown, an embodiment of the utility model provides a rear-flip hood for a loader, comprising a hood body 1, an electric push rod 2 and a pair of fixed side panels 3; the hood body 1 is an integral structure integrating left and right side panels, a top panel and a rear windshield panel.

[0029] like Figure 2 As shown, the front end of the electric push rod 2 is hinged to the lower right-angle inner edge of the left side plate of the hood body 1. Specifically, the front end of the electric push rod 2 is hinged to the lower right-angle inner edge of the left side plate of the hood body 1 through the upper mounting point 22. The rear end of the electric push rod 2 is also connected to an electric push rod mounting seat 21, and the electric push rod 2 is a telescopic structure. Specifically, the electric push rod 2 also includes an inner push rod 23 and an outer push rod 24 that are nested with each other. The telescopic adjustment of the electric push rod 2 can be achieved by changing the embedded margin of the inner push rod 23 in the outer push rod 24; more specifically, the embedded margin of the inner push rod 23 in the outer push rod 24 can be changed by selecting a spring or changing the pressure. Therefore, the electric push rod 2 can drive the hood body 1 to rise and fall during the telescopic process, thereby realizing the overall backward flipping of the hood body 1.

[0030] Specifically, the electric push rod mounting seat 21 is fixed on the loader frame base to provide force support for the electric push rod; the electric push rod mounting seat 21 is a four-corner square table structure, wherein the four corners are fixed on the loader frame base, and two left-right symmetrical ear plates are arranged above the electric push rod mounting seat 21 for fixing the lower mounting point 25 of the electric push rod 2.

[0031] When the electric push rod is driven, the rear end of the electric push rod 2 is tightly fixed on the electric push rod mounting seat 21. As the electric push rod 2 continues to extend, the front end of the electric push rod 2 slowly rises against the left side panel of the hood hinged thereto. Since the left and right side panels, the top panel and the rear windshield panel in the hood body 1 are an integrated structure, the entire hood body 1 gradually flips backwards as the electric push rod 2 extends. When it flips backwards to the expected angle, the electric push rod 2 is controlled to stop moving. After the inspection is completed, the hood can be restored to its initial position by controlling the electric push rod to retract.

[0032] In addition, the rear-flip hood of the loader provided in the embodiment of the utility model further includes a motor hood, which is also arranged on the inner side of the left side plate of the hood body and is located adjacent to the front end of the electric push rod; a motor is installed inside the motor hood, which can drive the electric push rod 2 when the motor is running, and provide power for the electric push rod 2 to extend and retract. At the same time, this design also saves the wiring distance between the motor and the electric push rod 2.

[0033] like Figure 3 As shown, when the hood body 1 is pushed by the electric push rod, in order to facilitate flipping, the utility model is provided with a flip hinge 4 at the bottom middle position of the rear windshield plate. Specifically, the flip hinge 4 includes a support seat 41 and a hinge plate 42; wherein, the lower part of the support seat is a four-corner square table-shaped structure for fixing on the loader frame base, and the upper part of the support seat is a slide-shaped structure, the upper end of which is hinged to the hinge plate 42 through a hinge shaft 43; the upper part of the hinge plate 42 is welded to the hood frame.

[0034] Therefore, the flip hinge 4 hinges the rear windshield plate to the loader frame base; with the flip hinge 4, when the left side plate is pushed by the electric push rod, the entire hood body 1 can not only be flexibly flipped, but also ensure the stability of the connection between the hood body 1 and the loader frame base.

[0035] The pair of fixed side plates 3 included in the rear flip hood of the loader provided by the utility model are completely identical in shape and size, both are approximately trapezoidal in shape, and can just coincide with the left and right side plates of the hood body.

[0036] Furthermore, a first fixing strip 31 is provided at the upper end of the fixed side panel 3, and a threaded hole is opened above the first fixing strip 31. The position and size of the threaded hole are consistent with the left and right side panels of the hood body 1. The hood body 1 can be fixed to the fixed side panel 3 by fixing bolts.

[0037] At the same time, a second fixing strip 32 and a plurality of protrusions 33 and grooves 34 are provided below the fixed side panel 3. One end of the second fixing strip 32 is fixed to the sharp outer edge of the lower left side panel 3 by bolts, and the other end is fixed to the frame base. The plurality of protrusions 33 and grooves 34 below the fixed side panel 3 correspond to the grooves and protrusions designed on the frame base, so that the fixed side panel 3 is firmly fixed to the frame base.

[0038] Working principle:

[0039] The utility model provides a rear-flip hood for a loader, comprising a hood body 1, an electric push rod 2 and a pair of fixed side panels 3; the hood body 1 is an integral structure with left and right side panels, a top panel and a rear windshield panel. When there is a need to open the hood (for example, it is necessary to repair the components under the hood), first, the staff removes the bolts between the left and right side panels and the fixed side panels for fixing the hood body; then, the motor inside the left side panel of the hood is turned on, and the motor drives the electric push rod 2 to extend. Since the rear end of the electric push rod 2 is firmly fixed on the loader frame base, the front end of the electric push rod 2 is slowly lifted against the left side panel of the hood hinged thereto, and since the left and right side panels, the top panel and the rear windshield panel in the hood body 1 are an integrated structure, the entire hood body 1 gradually flips backward with the extension of the electric push rod 2 under the combination of the flip hinge 4, and when it flips backward to the expected angle, the electric push rod 2 is controlled to stop moving; after the maintenance is completed, the hood can be restored to its initial position by controlling the electric push rod to retract.

[0040] The utility model sets the entire loader hood body as an integral structure. When the hood needs to be opened, the electric push rod can be controlled to extend and retract to drive the hood to rise and fall, thereby realizing the integral rearward flip of the hood, which has a larger maintenance space and is easy to operate; at the same time, it also ensures better sealing, better protection for components, batteries, and high-voltage wiring harnesses under the hood, and improves the safety of the entire vehicle. Moreover, with the support of the electric push rod, the hood is no longer affected by uncontrollable factors such as weather and temperature, and its applicability is stronger.

[0041] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
