Description

Technical Field

[0001] The present application relates to the technical field of electric vehicles, and in particular to a high-strength electric vehicle frame. Background Art

[0002] Electric vehicles use batteries as their energy source and control their speed through controllers, motors and other components. They are mainly used for security patrols, food delivery, express delivery and even heavy object transportation.

[0003] In order to improve the safety, stability and durability of electric vehicles, existing electric vehicles usually use high-strength electric vehicle frames. High-strength electric vehicle frames are generally provided with storage slots for installing batteries to ensure that the batteries can be firmly fixed inside the frame to prevent displacement or falling off during driving. The storage slots are mostly closed structures with a dustproof plate covered on the top.

[0004] The above-mentioned existing technical solutions have the following defects: when the electric vehicle is running for a long time, the heat dissipation effect of the battery installed in the storage tank is poor, and the high temperature can easily cause damage to the battery, thereby reducing the service life of the battery. Utility Model Content

[0005] In order to improve the heat dissipation efficiency of the battery, the present application provides a high-strength electric vehicle frame.

[0006] The above technical objectives of this application are achieved through the following technical solutions:

[0007] A high-strength electric vehicle frame includes a main beam tube, a head tube is fixedly connected to the main beam tube, a section of the circumferential wall of the main beam tube is fixedly connected to a side tube, at least two side tubes are provided, one end of the side tube is fixedly connected to a connecting plate, the connecting plate is connected to the two side tubes, a section of the two side tubes is bent and fixedly connected to an extension tube, a front mounting seat is fixedly connected to the extension tube, a rear mounting seat is fixedly connected to the extension tube, a storage groove is fixedly connected to the extension tube, a heat dissipation frame is fixedly connected to the extension tube, a guide plate is provided on the heat dissipation frame, an air outlet is opened on the side wall of the storage groove, and a mudguard is fixedly connected to the side plate of the storage groove.

[0008] By adopting the above technical solution, the guide plate guides the air flowing into the storage slot when the electric vehicle is running, and at the same time can prevent stones from entering the storage slot. The mudguard can prevent dirt, sand and other debris carried by the rear wheel of the electric vehicle from entering the storage slot or damaging the battery when it rotates. The air passes through the battery to take away the heat and is discharged from the air outlet, which can improve the heat dissipation efficiency of the battery and ensure the normal operation of the battery.

[0009] Optionally, the guide plate is rotatably connected to the heat dissipation frame, a fixed block is fixed on the heat dissipation frame, a guide rod is passed through the fixed block, one end of the guide rod extends to the bottom of the heat dissipation frame and is rotatably connected to the guide plate, the other end of the guide rod extends to the outside of the fixed block and is fixed with a pressure plate, a baffle is fixed on the guide rod, the baffle slides in the fixed block, a first elastic member is sleeved on the guide rod, and the first elastic member is located between the baffle and the inner wall of the fixed block.

[0010] By adopting the above technical solution, the downforce control deflector rotates open when the driver is riding, which can enable the electric vehicle to normally dissipate heat from the battery installed in the storage slot while driving. After the driver leaves, the deflector rotates to close, which can prevent dust and rainwater from entering the storage slot, ensuring that rainwater does not enter the storage slot when the electric vehicle is parked and charging.

[0011] Optionally, a slide rail is fixed to the extension tube, a slide groove matching the slide rail is provided on the side wall of the heat dissipation rack, a locking block is fixed in the extension tube, a locking tongue is slidably provided in the locking block, one end of the locking tongue is fixed to a second elastic member, and one end of the second elastic member is fixed to the inner wall of the extension tube.

[0012] By adopting the above technical solution, the lock tongue can limit the heat dissipation rack, making it easy to clean and maintain the heat dissipation rack and the guide plate in a timely manner, thereby ensuring the heat dissipation efficiency of the battery installed in the storage slot.

[0013] Optionally, a section of the receiving groove is processed to form a buffer groove, and a ventilation hole is opened on the side wall of the buffer groove.

[0014] By adopting the above technical solution, the ventilation holes can increase the amount of air entering the storage slot, improve the heat dissipation efficiency of the battery in the storage slot, and the bottom of the buffer slot protrudes downward, which can ensure that the buffer slot and the battery installed in the buffer slot are not damaged when the bottom of the electric vehicle is hit.

[0015] Optionally, a partition is formed at the connection between the buffer groove and the receiving groove, and the plate surface of the partition is inclined toward the bottom of the buffer groove.

[0016] By adopting the above technical solution, the partition can block rainwater and sand from entering the storage groove through the ventilation hole.

[0017] Optionally, the bottom of the buffer groove is integrally formed with a reinforcing rib, and a guard plate is formed on the reinforcing rib.

[0018] By adopting the above technical solution, the reinforcing ribs can increase the overall structural strength of the buffer slot and increase the protection of the buffer slot to the battery installed in the storage slot. At the same time, the guard plate can guide the air flowing through the ventilation holes, so that the air is concentrated and blown to the battery in the storage slot, thereby improving the heat dissipation efficiency of the battery.

[0019] Optionally, a fixing plate is fixed to the bottom of the storage groove.

[0020] By adopting the above technical solution, the fixing plate can separate the batteries installed in the storage slot, increase the gap between the batteries, and improve the heat dissipation efficiency of the batteries. During installation, the batteries are clamped and fixed between the fixing plates or between the fixing plates and the storage slot, which can increase the stability of the battery fixation and reduce the sliding of the batteries in the storage slot.

[0021] Optionally, a pull plate is fixed to the side wall of the storage groove.

[0022] By adopting the above technical solution, the pull plate can increase the stability of the fixation between the storage slot and the extension tube, ensuring that the storage slot and the battery installed therein will not fall off.

[0023] In summary, this application has the following technical effects:

[0024] 1. The heat dissipation rack, deflector, air outlet and mud guard can prevent dirt, sand and other debris carried by the electric vehicle's rear wheels from entering the storage slot or damaging the battery. Air passes through the battery to remove heat and is discharged from the air outlet, which can improve the heat dissipation efficiency of the battery and ensure its normal operation.

[0025] 2. By providing the fixing block, guide plate, pressure plate and first elastic member, the battery installed in the storage slot can be cooled normally while the electric vehicle is driving. After the driver leaves, the guide plate rotates to close, which can prevent dust and rain from entering the storage slot, ensuring that rainwater does not enter the storage slot when the electric vehicle is parked and charging;

[0026] 3. By setting up the slide rail, slide groove, lock block, lock tongue and second elastic member, the heat dissipation rack can be limited, which is convenient for timely cleaning and maintenance of the heat dissipation rack and guide plate, and ensures the heat dissipation efficiency of the battery installed in the storage slot.

[0031] The present application is further described in detail below with reference to the accompanying drawings.

[0032] The present application discloses a high-strength electric vehicle frame, referring to Figure 1 The electric vehicle frame includes a main beam tube 1, one end of the main beam tube 1 is welded with a head tube 11, a side tube 12 is welded to a section of the peripheral wall of the main beam tube 1 away from the head tube 11, there are two side tubes 12 and they are symmetrically arranged on the peripheral wall of the main beam tube 1, a section of the side tube 12 close to the main beam tube 1 is bent toward the main beam tube 1, and sections of the two side tubes 12 away from the main beam tube 1 are located on the same plane and are parallel to each other, and a connecting plate 14 is welded to one end of the side tube 12 away from the main beam tube 1, and both ends of the connecting plate 14 are respectively connected to the two side tubes 12. The side tube 12 is bent at a section away from the main beam tube 1 and welded with an extension tube 13. The extension tube 13 is U-shaped and bent near the side tube 12. The two ends of the extension tube 13 are respectively welded to the two side tubes 12. A front mounting seat 131 for fixing the electric vehicle seat is welded together on the two extension tubes 13. The section of the extension tube 13 away from the side tube 12 is bent downward. The ends of the two extension tubes 13 away from the side tube 12 are welded together with a rear mounting seat 132 for fixing the electric vehicle seat. The section of the extension tube 13 close to the side tube 12 is welded with a receiving groove 2. The receiving groove 2 is located at the bottom of the extension tube 13. The side walls on both sides of the length direction of the receiving groove 2 are welded with pull plates 21. The pull plates 21 are made of strip metal plates. The pull plates 21 are vertically arranged and welded to the peripheral wall of the extension tube 13 at one end away from the receiving groove 2.

[0033] A section of the extension tube 13 close to the side tube 12 is connected to the heat dissipation frame 3, the heat dissipation frame 3 is located between the two extension tubes 13 and the bottom of the heat dissipation frame 3 is abutted against the connecting plate 14, the heat dissipation frame 3 is made of bent strip metal plates and is rectangular, and guide plates 31 are provided on the side walls at both ends of the length direction of the heat dissipation frame 3. Multiple guide plates 31 are provided in sequence along the length direction of the heat dissipation frame 3, and the side wall of the storage groove 2 close to the rear mounting seat 132 is provided with an air outlet 22. A mudguard 4 is welded to the side wall of the storage groove 2 close to the rear mounting seat 132, and the bottom of the mudguard 4 is located below the air outlet 22. One end of the mudguard 4 is fixed to the storage groove 2, and the other end is welded to the peripheral wall of the rear mounting seat 132, and the area of ​​the mudguard 4 is larger than the area of ​​the air outlet 22.

[0034] When using the electric vehicle frame, the battery is installed in the storage slot 2. When riding the electric vehicle, air enters the storage slot 2 through the guide plate 31. The air is guided by the guide plate 31 and blown toward the battery, and the heat generated by the battery during operation is discharged from the air outlet 22. The mudguard 4 can prevent dirt, sand, and other debris carried by the rear wheel of the electric vehicle from entering the storage slot 2 or damaging the battery when it rotates. The air flowing into the storage slot 2 when the electric vehicle is running is guided by the guide plate 31, and at the same time, it can prevent stones from entering the storage slot 2. The air passes through the battery to take away the heat and is discharged from the air outlet 22, which can improve the heat dissipation efficiency of the battery and ensure the normal operation of the battery.

[0035] Reference Figure 2 and Figure 3 The deflector plate 31 is rotatably connected to the heat dissipation frame 3, and the deflector plate 31 can rotate along one side in its length direction as an axis. The top of the heat dissipation frame 3 is fixed with a fixing block 32 by bolts, and a guide rod 33 is passed through the fixing block 32. One end of the guide rod 33 extends to the bottom of the heat dissipation frame 3 and is rotatably connected to the other side of the deflector plate 31. The other end of the guide rod 33 extends to the outside of the fixing block 32 and is welded to a pressure plate 34. A section of the guide rod 33 located in the fixing block 32 is welded with a baffle 331, which slides inside the fixing block 32. A first elastic member 332 is sleeved on the guide rod 33. In this embodiment, the first elastic member 332 is a spring. One end of the first elastic member 332 abuts against the plate surface of the baffle 331 close to the deflector plate 31, and the other end abuts against the side wall of the fixing block 32 facing away from the deflector plate 31.

[0036] When the electric vehicle frame is used, the seat cushion is mounted on the front mounting seat 131. When the driver sits on the seat, the seat cushion is forced to move downward and press the pressure plate 34. The pressure plate 34 pushes the guide rod 33 to slide along the fixed block 32 and drives the guide plate 31 to rotate downward, so that the gap between the guide plates 31 increases. When the electric vehicle is running, air can pass through the guide plate 31 into the storage slot 2 and cool the battery. When the driver leaves the seat cushion after parking, the seat cushion is no longer under pressure, and the elastic force of the first elastic member 332 is The baffle, guide rod 33 and pressure plate 34 are pushed toward the seat cushion, driving the deflector 31 to rotate upward, so that the gap between the deflector 31 is reduced and the plate surfaces abut each other. The deflector 31 is controlled to rotate open by the downward pressure when the driver is riding, so that the battery installed in the storage slot 2 can be normally cooled while the electric vehicle is driving. After the driver leaves, the deflector 31 rotates to close, which can prevent dust and rainwater from entering the storage slot 2, ensuring that rainwater does not enter the storage slot 2 when the electric vehicle is parked and charging.

[0037] Reference Figure 2 The extension tube 13 is welded with a slide rail 35 at a section near the side tube 12. Two slide rails 35 are provided and the length direction of the slide rail 35 is the same as the length direction of the extension tube 13. The two slide rails 35 are respectively arranged on the opposite side of the peripheral wall of the two extension tubes 13. The side walls at both ends of the length direction of the heat dissipation frame 3 are provided with slide grooves 36 that cooperate with the slide rail 35. A locking block 37 is fixedly connected to the extension tube 13. The locking block 37 is located at the end of the slide rail 35 away from the side tube 12. A locking tongue 38 is slidingly provided in the locking block 37. The locking tongue 38 is made of a strip metal plate and one end is processed to form an inclined surface. The inclined surface of the locking tongue 38 is located outside the locking block 37 and away from the slide rail 35. The other end of the locking tongue 38 is welded with a second elastic member 39. In this embodiment, the second elastic member 39 is a spring, and the end of the second elastic member 39 away from the locking tongue 38 is welded to the inner wall of the locking block 37.

[0038] The detachable connection of the heat sink 3 is convenient for timely cleaning and maintenance of the heat sink 3 and the guide plate 31, thereby ensuring the heat dissipation efficiency of the battery installed in the storage slot 2.

[0039] Reference Figure 3A section of the receiving groove 2 near the connecting plate 14 is processed to form a downwardly protruding buffer groove 5. Ventilation holes 51 are provided at the bottom of the side walls at both ends of the length direction of the buffer groove 5. A partition 52 is extended upward at the connection between the buffer groove 5 and the receiving groove 2, and the plate surface of the partition 52 is inclined to the bottom of the buffer groove 5.

[0040] When the electric vehicle frame is used, the ventilation holes 51 can increase the amount of air entering the storage slot 2, thereby improving the heat dissipation efficiency of the battery in the storage slot 2. The partition 52 can block rainwater and sand from entering the storage slot 2 through the ventilation holes 51, and protrude downward through the bottom of the buffer slot 5, thereby ensuring that the buffer slot 5 and the battery installed in the buffer slot 5 are not damaged when the bottom of the electric vehicle is hit.

[0041] Reference Figure 3 The bottom of the buffer groove 5 is integrally formed with a reinforcing rib 53 along its width direction. There are two reinforcing ribs 53 and they are respectively located at the openings of the two ventilation holes 51. The side of the reinforcing rib 53 away from the bottom of the buffer groove 5 is processed to form a guard plate 54.

[0042] When the electric vehicle frame is used, the reinforcing ribs 53 can increase the overall structural strength of the buffer tank 5, thereby increasing the protection of the buffer tank 5 to the battery installed in the storage tank 2. At the same time, the guard plate 54 can guide the air flowing through the ventilation holes 51, so that the air is concentrated and blown toward the battery in the storage tank 2, thereby improving the heat dissipation efficiency of the battery.

[0043] Reference Figure 3 A fixing plate 23 is welded to the bottom of the storage tank 2 , and multiple fixing plates 23 are arranged at intervals along the length direction of the storage tank 2 , and the plate surface of the fixing plate 23 is perpendicular to the bottom of the storage tank 2 .

[0044] When using the electric vehicle frame, the fixing plate 23 can separate the batteries installed in the storage slot 2, increase the gap between the batteries, and improve the heat dissipation efficiency of the batteries. During installation, the batteries are clamped and fixed between the fixing plates 23 or between the fixing plates 23 and the storage slot 2, which can increase the stability of the battery fixation and reduce the sliding of the batteries in the storage slot 2.
