Description

Technical Field

[0001] The present invention relates to the technical field of engine hoods, and particularly to a quantitative engine hood for a new energy vehicle. Background Art

[0002] The engine hood is an external component on a vehicle used to cover the engine (or motor), usually located at the front of the vehicle body. Its main functions are to protect the engine from the external environment, provide necessary heat dissipation, air flow, and an easily accessible maintenance passage. The engine hood is not only crucial for the safety and performance of the engine but also plays an important aerodynamic role in the overall vehicle design.

[0003] The prior art document with the publication number CN216611368U provides an engine hood for a new energy vehicle. By means of a pressing plate, a pressing strip, a connecting rod, and a U-shaped pressing rod, the traditional connection method of multiple press-type fasteners is changed. The connecting rod and the U-shaped pressing rod on the surface of the pressing strip of the pressing assembly are used to press and fix the composite noise reduction plate, and then a locking bolt is used to penetrate the pressing plate for locking and fixing, which is convenient for assembly and disassembly and improves the loading and unloading efficiency.

[0004] However, this prior art has certain limitations in battery reinforcement. When used on new energy vehicles, it is not convenient to assist in reinforcing the battery at the front of the vehicle, making the fixing screws of the battery prone to loosen during vehicle driving, and then causing the battery to shake. If the battery at the front part of the vehicle cannot be effectively reinforced, the battery will shake and be unstable, which will have an adverse impact on the safety, performance, and service life of the vehicle.

[0005] In summary, in the prior art, there is a lack of technology for using battery reinforcement in the engine hood of new energy vehicles. Summary of the Invention

When the battery reinforcement plate is pressurizing and fixing, the damage caused by these particulate matters can be effectively avoided. This design can ensure the cleanliness of the battery surface, thereby improving the fixing effect of the reinforcement plate, extending the battery service life, and reducing potential safety hazards.

The ramp block 302 realizes the function of contacting with the vehicle body and automatically retracting when the hood body 1 is closed.

[0033] like Figure 4 As shown, the pressurizing mechanism 4 includes two rotating shafts 401, which are rotatably connected to the fixed plate 2, and one end of the rotating shaft 401 is fixedly connected with a gear A402, which is meshed with the transmission rack 303 for transmission, and two pressurizing connecting rod groups 403 are rotatably connected on the rotating shaft 401 in a symmetrical structure, and the other end of the pressurizing connecting rod group 403 is rotatably connected with a hinge seat 405, and the hinge seat 405 is fixedly connected to the fixed seat 5, and one end of one of the pressurizing connecting rod groups 403 connected to the fixed seat 5 is fixedly connected with a driving wheel 404. The inclined surface of the inclined plane block 302 will contact the vehicle body and be retracted, and at this time, it will drive the connected sliding frame 301 to move, so that the sliding frame 301 drives the transmission rack 303 to move, so that the transmission rack 303 drives the gear A402 to rotate, and the gear A402 drives the connected rotating shaft 401 to rotate. At this time, the rotating shaft 401 will drive the connected pressurized connecting rod group 403 to rotate, so that the pressurized connecting rod group 403 drives the battery reinforcement plate 6 on the lower side of the fixing seat 5 to press on the battery for reinforcement.

[0034] By providing a pressurizing mechanism 4 and a battery reinforcement plate 6, when the hood main body 1 is closed, the pressurizing mechanism 4 can automatically drive the battery reinforcement plate 6 to assist in pressurizing and fixing the battery under the drive of the transmission mechanism 3, thereby effectively improving the safety and stability of the battery, reducing the risks caused by shaking or loosening of the battery, and optimizing the vehicle's handling, durability and maintenance efficiency.

[0035] like Figure 5 As shown, two tension springs 501 are fixedly connected and arranged on the fixing seat 5 in a symmetrical structure, and the other end of the tension spring 501 is fixedly connected and arranged with the fixing plate 2. A plurality of fixed racks 502 are fixedly connected and arranged on the lower surface of the fixing seat 5, and a slide groove 503 is provided on the fixing seat 5. The tension spring 501 realizes that the battery reinforcement plate 6 is automatically retracted and reset when the hood body 1 is opened.

[0036] like Figure 6 As shown, a heat sink 601 is fixedly connected to the upper surface of the battery reinforcement plate 6, and a slope is provided at one end of the heat sink 601 to reduce wind resistance. The heat sink 601 enables the battery reinforcement plate 6 to fully dissipate heat at the contact point with the battery.

A driven wheel 703 is fixedly connected to the end of the swing rod 702 connected to the fixed seat 5. The driven wheel 703 is meshed and driven with the driving wheel 404. The pressure connecting rod group 403 drives the connected driving wheel 404 to rotate, so that the driving wheel 404 drives the swing rod 702 connected to the driven wheel 703 to swing, so that the other end of the swing rod 702 slides in the guide groove 701, thereby driving the movable bracket 704 to slide in the chute 503, so that the movable bracket 704 drives the connected movable frame 7 to move.

[0038] As Figure 8 shown in the figure, the cleaning mechanism 8 includes a bent scraper 801. The bent scraper 801 is fixedly connected to the movable frame 7. The inner wall and the bottom end of the bent scraper 801 are respectively in sliding contact with the upper surface of the heat sink 601 and the battery reinforcement plate 6. An inclined surface is formed on one side of the bent scraper 801. The inclined surface formed on one side of the bent scraper 801 serves to reduce wind resistance.

[0039] Fixed frames 802 are fixedly connected to both sides of the bent scraper 801. A universal joint 803 is rotatably connected to the fixed frame 802. A rotating scraping bar 804 is fixedly connected to one end of the universal joint 803. The rotating scraping bar 804 is in frictional contact with the side wall of the heat sink 601. A gear B805 is fixedly connected to the other end of the universal joint 803. The gear B805 is meshed and driven with the fixed rack 502. When the movable frame 7 moves, it drives the connected bent scraper 801 to move. At the same time, under the action of the fixed rack 502, the gear B805 rotates. The gear B805 drives the connected universal joint 803 to rotate, so that the universal joint 803 drives the connected rotating scraping bar 804 to rotate, and cooperates with the bent scraper 801 to clean the outer wall of the heat sink 601 and the upper surface of the battery reinforcement plate 6.

[0040] As Figure 9As shown in the figure, a square plug 901 is slidably fitted to the inner wall of the suction and pressure box 9. One end of the square plug 901 is fixedly connected to a contact rod 902. The contact rod 902 is slidably fitted through one side of the suction and pressure box 9. The outer end of the contact rod 902 is in movable contact with the movable frame 704. One side of the square plug 901 is fixedly connected to a spring 903. The other end of the spring 903 is fixedly connected to the inner wall of the suction and pressure box 9. One side of the suction and pressure box 9 is fixedly connected through penetration with an air inlet pipe 904. The suction and pressure box 9 is fixedly connected through penetration at the lower side of the air inlet pipe 904 with an air outlet pipe 905. The other end of the air outlet pipe 905 extends to the lower surface of the battery reinforcement plate 6. Check valves are fixedly installed in both the air inlet pipe 904 and the air outlet pipe 905. When the movable frame 704 moves to one side, at this time the contact rod 902 is not restricted. Under the action of the spring 903, it will drive the square plug 901 to move, so that the square plug 901 presses out the air in the suction and pressure box 9 and sprays it out through the air outlet pipe 905. When the movable frame 704 moves, it can contact the contact rod 902, thereby driving the square plug 901 to move, and drawing air into the suction and pressure box 9 through the air inlet pipe 904.

[0041] Working principle: When the engine hood main body 1 is closed, at this time the inclined surface of the inclined block 302 will contact the vehicle body and retract, and at this time it will drive the connected sliding frame 301 to move, so that the sliding frame 301 drives the transmission rack 303 to move, so that the transmission rack 303 drives the gear A 402 to rotate, so that the gear A 402 drives the connected rotating shaft 401 to rotate. At this time, the rotating shaft 401 will drive the connected pressurizing link group 403 to rotate, so that the pressurizing link group 403 drives the battery reinforcement plate 6 under the fixed seat 5 to press on the battery for reinforcement;

[0042] Before the battery reinforcement plate 6 contacts the battery, the pressurizing link group 403 will drive the connected driving wheel 404 to rotate, so that the driving wheel 404 drives the swing rod 702 connected to the driven wheel 703 to swing, so that the other end of the swing rod 702 slides in the guide groove 701, thereby driving the movable frame 704 to slide in the sliding groove 503, so that the movable frame 704 drives the connected moving frame 7 to move. When the movable frame 704 moves to one side, at this time the contact rod 902 is not restricted. Under the action of the spring 903, it will drive the square plug 901 to move, so that the square plug 901 presses out the air in the suction and pressure box 9 and sprays it out through the air outlet pipe 905 to blow away the particulate matter on the surface of the battery;

[0043] At the same time, when the moving frame 7 moves, it will drive the connected bent scraper 801 to move. At the same time, under the action of the fixed rack 502, it will cause the gear B 805 to rotate. The gear B 805 will drive the connected universal joint 803 to rotate, so that the universal joint 803 drives the connected rotating scraper 804 to rotate, and cooperates with the bent scraper 801 to clean the outer wall of the heat sink 601 and the upper surface of the battery reinforcement plate 6 to ensure the heat dissipation efficiency of the heat sink 601 and the battery reinforcement plate 6.
