Description

Technical Field

[0001] The utility model relates to the technical field of engine hoods, in particular to an engine hood and an engineering vehicle. Background Art

[0002] Batteries, electrical wiring harnesses, heat sinks and other components are arranged under the hood of the electric excavator. According to the thermal management requirements of the heat sink, it is necessary to design air inlets and outlets at corresponding positions on the hood according to the air inlet and outlet directions. Existing hoods are usually equipped with vents to help the engine and other key components dissipate heat and prevent overheating. However, under high load or high temperature environments, it is difficult to achieve a good heat dissipation effect only through the design of vents, which causes the engine to overheat and affects performance and life. In addition, most hoods have deficiencies in waterproof design. Especially when working in heavy rain or puddles, moisture may penetrate into the hood, causing a short circuit in the electrical system or rust on mechanical parts. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiencies in the prior art and to provide a hood and an engineering vehicle that effectively reduce the impact of moisture on the equipment through the protective function of the water retaining structure and the drainage function of the drainage structure, thereby reducing the equipment failure rate and extending the service life of the equipment.

[0004] In order to achieve the above objectives, this application is implemented by adopting the following technical solutions:

[0005] In a first aspect, the present application provides a hood, comprising a top plate 1 and side plates 2 disposed on both sides of the top plate 1, wherein at least one of the side plates 2 is provided with a plurality of vents; the side plates 2 are connected with a water retaining mechanism for preventing water from entering the hood through the vents, and / or a drainage mechanism capable of discharging water entering the hood through the vents;

[0006] The water retaining mechanism comprises a water retaining plate 10 connected to the outer side surface of the side plate 2;

[0007] The drainage mechanism includes an air guide cover 7 connected to the inner side surface of the side plate 2, and the air guide cover 7 and the side plate 2 are enclosed to form a water receiving trough opening upward.

[0011] Optionally, the air guide cover 7 is tilted, and the angle between the air guide cover 7 and the side panel 2 is an acute angle.

[0012] Optionally, at least one reinforcing plate 3 is connected between the water retaining plate 10 and the side plate 2 .

[0013] Optionally, the side panel 2 includes a first side panel 21 and a second side panel 22, and a plurality of ventilation holes are provided on the first side panel 21 and the second side panel 22; the first side panel 21 is connected to the water retaining mechanism, and the second side panel 22 is connected to the drainage mechanism.

[0014] Optionally, the top plate 1 extends outward beyond the second side plate 22 and bends downward to form a flange.

[0015] In a second aspect, the present application further provides an engineering vehicle, comprising a hood as described in any one of the above items. Compared with the prior art, the present application achieves the following beneficial effects:

[0016] 1. The integrated water-blocking and drainage functional design improves the protection level of the hood. The synergistic effect of the water-blocking plate and the wind guide cover effectively prevents water from entering. The water-blocking plate is installed on the side panel of the hood, which can directly prevent rain or other liquids from entering the hood. This design is particularly suitable for outdoor equipment or machinery exposed to humid environments to prevent internal equipment from being eroded or damaged by water. The protection of the water-blocking plate and the drainage mechanism formed by the wind guide cover can effectively reduce the impact of moisture on the internal equipment of the hood, thereby reducing the equipment failure rate and extending the service life of the equipment.

[0017] 2. The air guide can not only guide the airflow entering the hood through the vents and help dissipate heat, but also act as a water baffle inside the side panel to block water. In addition, the air guide can also collect the water entering the hood in the water tank, so that the water can be naturally discharged through the vents without the need for additional drainage equipment or power. This self-draining design reduces the need for manual drainage and cleaning, and reduces maintenance costs and workload.

[0018] In summary, the hood provided by the present application can be applied to engineering vehicles, such as electric excavators. The hood helps to maintain the normal operation of the engineering vehicle in high humidity or rainy environments, prevent overheating or moisture accumulation, and enable the hood to perform well in different climatic conditions, especially in rainy and humid environments, thereby increasing the scope of application of engineering vehicles and enabling them to work normally in a wider range of environments.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. In addition, the technical features involved in the different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] Embodiment 1:

[0028] The hood provided by the embodiment of the utility model comprises a top plate 1 and side plates 2 arranged on both sides of the top plate 1, and at least one of the side plates 2 is provided with a plurality of vents for achieving ventilation and heat dissipation inside the hood. Optionally, the side plates 2 can be made of steel, aluminum or composite materials, and evenly distributed vents can be provided on the plates, or Figure 2 As shown, a metal grid 4 is used.

[0029] like Figure 1 As shown, the side plate 2 is connected with a water retaining mechanism for preventing rainwater or other liquids from entering the hood through the vents, and the water retaining mechanism includes a water retaining plate 10 connected to the outer side of the side plate 2. The water retaining plate 10 is installed at the upper end of the vents of the side plate 2, and the two ends of the water retaining plate 10 are gathered toward the two sides close to the vents to form an inverted U-shaped design, effectively forming a water retaining area, which can better block rainwater and liquids from above or from the sides, and prevent water from directly entering the hood. In addition, this design can reduce the impact of wind on the hood, reduce wind resistance, and prevent the problem of water backflow in strong wind environments.

[0030] Optional, such as Figure 3 As shown, a drainage mechanism can also be provided on the side panel 2, and the drainage mechanism can discharge the rainwater or other liquid from the outside that enters the hood through the vent. It should be noted that the drainage mechanism and the water retaining mechanism can be connected to the same side panel 2 at the same time, so as to achieve a better waterproof effect of external protection and internal drainage. When both side panels 2 are provided with vents, the drainage mechanism and the water retaining mechanism can also be separately arranged on the two side panels 2. At this time, when the hood is installed on the engineering vehicle, the side panel 2 connected with the water retaining mechanism can be directed toward the windward side of the engineering vehicle. When wind and rain come from one side, the side panel 2 connected with the water retaining mechanism can effectively prevent rainwater from entering the hood, protecting the engine and other important components; the side panel 2 connected with the drainage mechanism can be installed on the leeward side or at a lower position, so that rainwater can be discharged smoothly from the hood, preventing water from accumulating inside.

[0031] As an embodiment of the present application, the drainage mechanism includes an air guide hood 7 connected to the inner side of the side panel 2, and the air guide hood 7 and the side panel 2 are enclosed to form a water receiving trough with an opening facing upward. As the name implies, the first function of the air guide hood 7 is to guide the wind, but not only that, the drainage mechanism of the present application forms a drainage mechanism with the help of the air guide hood 7, so that the air guide hood 7 can not only guide the airflow entering the hood through the vent and help dissipate heat, but also act as a water baffle 10 inside the side panel 2 to play a water-blocking function. Furthermore, the air guide hood 7 can also collect the water entering the hood in the water receiving trough, so that the water is naturally discharged through the vent without the need for additional drainage equipment or power. This self-draining design reduces the need for manual drainage and cleaning, and reduces maintenance costs and workload.

[0032] In actual use, the user can control the water storage space of the water tank by adjusting the installation position of the lower edge of the wind guide cover 7 according to actual needs. When the motor component protected by the cover has a large power and dissipates more heat, the water storage space for receiving water can be appropriately increased. The stored rainwater or other liquids from the outside can absorb heat through vaporization, further reducing the temperature inside the cover shell and improving the heat dissipation effect. Specifically, the lower edge of the wind guide cover 7 can be moved downward to make it much lower than the setting height of the vent, or the length of the wind guide cover 7 can be extended.

[0033] Optional, such as Figure 3 As shown, the top plate 1 extends outward beyond the side plate 2 and bends downward to form a flange. The flange design structure can be used in conjunction with the drainage mechanism. The flange design of the top plate 1 can block part of the rainwater or other liquids from entering the hood through the vents, and the flange can guide the water flow along the curve and away from the vents, thereby reducing the retention and accumulation of moisture on the outer surface of the hood top plate 1, which helps to more effectively prevent water.

[0034] Embodiment 2:

[0035] This embodiment is improved on the basis of the first embodiment. Figure 3 As shown, the drainage mechanism further includes a baffle 6 and a bottom plate 9, and the side plate 2 is connected to both ends of the air guide cover 7 through the baffle 6, and is connected to the bottom of the air guide cover 7 through the bottom plate 9. To ensure that the water receiving trough has a good sealing performance, the bottom plate 9 and the air guide cover 7 can be bent and formed as a whole, and the bottom plate 9 and the side plate 2, and the baffle 6 and the side plate 2 can be sealed and welded. As an alternative, other sealing connection structures can also be used.

[0036] Optionally, additional reinforcing ribs may be provided inside the side panel 2. As shown in the figure, a left reinforcing rib 5 and a right reinforcing rib 8 are provided on both sides of the side panel 2. By providing reinforcing ribs, the baffle 6 of the drainage mechanism is fixedly connected to the side panel 2 of the hood, and additional support is provided for the side panel 2 of the hood, which can effectively prevent the side panel 2 from being deformed or broken during use.

[0037] Optionally, the air guide 7 is tilted inside the hood so that the angle between the air guide 7 and the side panel 2 is an acute angle. On the one hand, the side panel 2 with vents and the tilted air guide 7 can guide the wind direction, achieve accurate heat dissipation during operation, and improve the cooling effect; on the other hand, when rainwater or other liquids from the outside pass through the side panel 2 with vents and enter the inside of the hood shell, the rainwater or other liquids from the outside will hit the surface of the air guide 7 due to the action of the external wind force. By setting a reasonable tilt angle of the air guide 7, the rainwater or other liquids from the outside will gather at the bottom of the formed water receiving trough under the action of gravity, and at this time, the wind force and gravity can form a balance, until the wind force is less than the gravity, the gathered rainwater or other liquids from the outside can be discharged from the air inlet under the tilted design.

[0038] When the height of the lower edge of the air guide cover 7 is lower than the height of the vent opening provided on the side panel 2, combined with the design of the bottom plate 9, the water storage depth of the water receiving trough is controlled by adjusting the distance between the bottom plate 9 and the lowest point of the vent opening provided on the side panel 2. For example, the bottom plate 9 is set at 2 cm from the lowest point of the vent opening provided on the side panel 2, so that the formed water receiving trough can have a water storage margin of 2 cm depth. When the water storage depth exceeds this value, it will be discharged through the vent opening provided on the side panel 2, and the stored external rainwater or other liquids can absorb heat through vaporization, further reducing the temperature inside the hood shell and improving the heat dissipation effect.

[0039] Optionally, after the water baffle 10 is fixed to the upper end of the vent of the side panel 2 by welding or bolting, a reinforcing plate 3 can be added to the welding or bolting position to disperse the stress and prevent the connection from breaking due to concentrated force. The reinforcing plate 3 can reduce the vibration and deformation of the water baffle 10, thereby improving the overall stability of the structure.

[0040] Optionally, the vents are designed to be diamond-shaped. Compared with circular or square vents, the diagonal of the diamond is longer and the slope is larger, which can enhance the rigidity of the material under torsion and bending forces. Under the action of external forces, the material around the diamond vents is less likely to deform, thereby improving the overall strength of the side panel 2.

[0041] Embodiment three:

[0042] The embodiment of the utility model also provides an engineering vehicle, which adopts the hood described in embodiment 1 or embodiment 2. The engineering vehicle can be an electric excavator, and components such as batteries, electrical wiring harnesses and heat dissipation devices can be arranged in the hood, so as to effectively reduce the influence of moisture on the components in the hood, thereby reducing the equipment failure rate and extending the service life of the equipment.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
