[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] See also Figure 1-5 The utility model provides a new technical solution: a new energy vehicle chassis structure, including a new energy vehicle chassis body 1, four new energy vehicle tires 2 are arranged on the new energy vehicle chassis body 1, and a buffer groove 3 is opened on the upper surface of the new energy vehicle chassis body 1;
[0026] A buffer mechanism is provided on the chassis body 1 of the new energy vehicle. The buffer mechanism is used to protect the battery of the new energy vehicle during driving. The buffer mechanism includes a new energy battery mounting plate 4. The new energy battery mounting plate 4 is slidably sleeved in the inner wall of the buffer groove 3.
[0027] The disassembly and assembly mechanism is on the new energy battery mounting plate 4 . The disassembly and assembly mechanism is used to replace the protective measures of the automobile heat dissipation holes. The disassembly and assembly mechanism includes four dustproof nets 17 , and the four dustproof nets 17 are symmetrically arranged on both sides of the new energy battery mounting plate 4 .
[0028] Furthermore, the buffer mechanism also includes four dampers 5, four springs 7 and four piston rods 6. The four dampers 5 are fixedly mounted on the upper surface of the new energy vehicle chassis body 1, the four springs 7 are fixedly mounted on the upper surface of the four dampers 5, the four piston rods 6 are slidably sleeved in the inner walls of the four dampers 5, and the four piston rods 6 are fixedly mounted on the lower surface of the new energy battery mounting plate 4.
[0029] Furthermore, the disassembly and assembly mechanism also includes eight buckles 18 , and the eight buckles 18 are respectively fixedly mounted on opposite surfaces of the four dustproof nets 17 .
[0030] Furthermore, four heat dissipation holes 8 are symmetrically provided on both sides of the new energy battery mounting plate 4, the inner walls of the four heat dissipation holes 8 are provided with two slots 9, and the inner walls of the two slots 9 are provided with spring slots 10, and the inner walls of the two spring slots 10 are provided with sliding holes 11.
[0031] Furthermore, eight slide grooves 15 are symmetrically provided on both sides of the new energy battery mounting plate 4 , and the eight slide grooves 15 are respectively communicated with the eight slide holes 11 .
[0032] Furthermore, the disassembly and assembly mechanism also includes a fixed rod 14, a second spring 13 and a block 12. The fixed rod 14 is slidably sleeved in the inner wall of the slide hole 11. The right end of the fixed rod 14 is fixedly installed with the block 12, and the rear surface of the block 12 is arranged in an inclined surface. The left surface of the block 12 is fixedly installed with the second spring 13, and the left end of the second spring 13 is fixed on the inner wall of the spring groove 10. When the chassis structure of the new energy vehicle is used, when the vehicle is running, an upward thrust is applied to the damper 5 through vibration, and the damper 5 moves upward while passing through the elastic potential energy of the spring 7. To reduce the upward force, and will not directly affect the new energy battery mounting plate 4, forming a buffer. When the dustproof net 17 needs to be installed, the buckle 18 fixedly installed on the rear surface of the dustproof net 17 is inserted into the slot 9. At this time, the buckle 18 hits the inclined surface of the card block 12 and applies a leftward thrust to the card block 12. The card block 12 applies pressure to the second spring 13 fixedly installed on the left surface to cause it to shrink. At the same time, the card block 12 applies a leftward thrust to the fixed rod 14, causing it to drive the fixed plate 16 to slide to the left in the slide groove 15. At this time, continue to insert the buckle 18 into the slot 9. At this time, the block 12 is no longer subjected to the pressure exerted by the buckle 18, and the second spring 13 is no longer subjected to force. At this time, the second spring 13 expands, and the second spring 13 pushes the block 12 fixedly installed at the right end to the right, so that it restricts the buckle 18 to prevent it from moving. When disassembly is required, by pushing the fixing plate 16 to slide to the left in the slide groove 15, the fixing plate 16 drives the fixing rod 14 fixedly installed at the front end to move to the left, and the fixing rod 14 drives the block 12 fixedly installed at the right end to move to the right. At this time, the block 12 no longer restricts the buckle 18, and the dustproof cover can be removed. The net 17 is removed, and the chassis structure of the new energy vehicle can form a buffer mechanism through the damper 5, the spring 7 and the piston rod 6 to reduce the vibration of the new energy battery module caused by the chassis bumps during the driving of the vehicle, which affects its work. It can reduce the impact of external forces on the energy battery module and improve the stability of the energy battery module. The chassis structure of the new energy vehicle can quickly replace the dustproof net 17 by snapping. Compared with the traditional dustproof net 17 installed by a bolt mechanism, the snap-on method can quickly disassemble and assemble the dustproof net, which is convenient for replacement.
[0033] Working principle: When the chassis structure of the new energy vehicle is in use, when the vehicle is running, an upward thrust will be applied to the damper 5 through vibration. While the damper 5 moves upward, the elastic potential energy of the spring 7 will reduce the upward force, and will not directly affect the new energy battery mounting plate 4, forming a buffer. When the dustproof net 17 needs to be installed, the buckle 18 fixedly installed on the rear surface of the dustproof net 17 is inserted into the slot 9. At this time, the buckle 18 hits the inclined surface of the card block 12 and applies a leftward thrust to the card block 12. The card block 12 applies pressure to the second spring 13 fixedly installed on the left surface to cause it to shrink. At the same time, the card block 12 applies a leftward thrust to the fixed rod 14, causing it to drive the fixed rod 14 to move. The fixed plate 16 slides to the left in the slide groove 15, and the buckle 18 continues to be inserted into the slot 9. At this time, the block 12 is no longer subjected to the pressure applied by the buckle 18, and the second spring 13 is no longer under force. At this time, the second spring 13 expands, and the second spring 13 pushes the block 12 fixedly installed at the right end to the right, so that it restricts the buckle 18 to prevent it from moving. When disassembly is required, by pushing the fixed plate 16 to slide to the left in the slide groove 15, the fixed plate 16 drives the fixed rod 14 fixedly installed at the front end to move to the left, and the fixed rod 14 drives the block 12 fixedly installed at the right end to move to the right. At this time, the block 12 no longer restricts the buckle 18, and the dustproof net 17 can be removed.
