Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicles, and more particularly to a hydraulic transmission mechanism for electric vehicles. Background Art

[0002] Electric vehicles are vehicles that use an onboard power source, an electric motor to drive the wheels, and comply with all road traffic and safety regulations. Their core principle is to store electrical energy in a battery pack and then convert it into mechanical energy through an electric motor to propel the vehicle.

[0003] When an electric vehicle brakes, the traditional braking system converts the vehicle's kinetic energy into heat through friction between the brake pads and discs, dissipating it into the air. Existing electric vehicles, however, recover this heat for secondary driving. Currently, many electric vehicles place the drive motor at the rear of the vehicle. This design, driven by a combination of factors including overall vehicle performance optimization and efficient space utilization, presents a new challenge. Because the front of an electric vehicle lacks the support and cushioning provided by large mechanical components like the engine in a traditional fuel-powered vehicle, it is more susceptible to severe damage in the event of a frontal collision.

[0004] In traditional fuel-powered vehicles, components such as the engine can disperse and absorb energy during a collision. However, electric vehicles lack this mechanism, making it difficult to effectively channel the energy. Instead, the energy directly impacts the front structure, exacerbating deformation and increasing the risk of injury to occupants. To address this issue, we propose a hydraulic transmission mechanism for electric vehicles. Summary of the Invention

[0005] The purpose of the present invention is to provide a hydraulic transmission mechanism for electric vehicles to solve the technical problem that many electric vehicles have a rear-mounted drive motor, which optimizes performance and space utilization, but lacks large components at the front to support and buffer the vehicle.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention utilizes the design of an isolation assembly, a connecting assembly, and a sliding assembly. When the brake system operates and completes a braking action, the brake pads generate high temperatures. At this time, the thermoelectric conversion module of the hydraulic energy conversion assembly absorbs the high temperature of the brake pads and converts it into energy, thereby driving the hydraulic drive module of the hydraulic energy conversion assembly. The hydraulic drive module, in turn, drives the first hydraulic rod and the transmission assembly. This causes the isolation assembly to be pushed by the transmission assembly, thereby sealing the active air intake grille. Simultaneously, the operation of the first hydraulic rod also forces the connecting assembly and the sliding assembly to rotate within the active air intake grille. On the one hand, the changes in the isolation assembly, connecting assembly, and sliding assembly significantly reduce the amount of air entering the active air intake grille, thereby increasing airflow resistance in front of the vehicle during movement, making forward movement more difficult and accelerating the vehicle's stopping in conjunction with the braking action. On the other hand, if a collision occurs during the braking process, the first hydraulic rod pushes the connecting assembly and the sliding assembly outward, thereby adding a buffer structure to the front of the electric vehicle, effectively providing additional cushioning protection for the driver and passenger, thereby improving the braking efficiency of the device and the protective effect on passengers in the event of a collision.

[0018] 2. The present invention also designs a transmission component and an isolation component. When braking, the hydraulic energy conversion component drives the first hydraulic rod and the second hydraulic rod to operate. When the second hydraulic rod operates, it pushes the gear plate forward. As the gear plate moves, the second gear rotates synchronously and drives one of the first gears to rotate. When the second hydraulic rod moves to the extreme position, the first gear and the second gear both rotate ninety degrees, so that the two adjacent isolation plates are in an overlapping state, thereby blocking outside air from entering the active air intake grille. In this way, it is more difficult for outside air to enter the active air intake grille when the vehicle brakes, and the contact area between the front of the vehicle and the air in front is increased, providing an auxiliary effect for the vehicle's braking action.

[0019] 3. The present invention also designs a connecting component and a sliding component. As the first hydraulic rod operates, the slide drives the connecting shell to flip at an angle, causing the connecting shell to flip along the second rotator. During the flipping process, the limit block slides in the limit groove to ensure that the docking sleeve always remains horizontal and connected to the first hydraulic rod. When the first hydraulic rod moves to the extreme position, the slide will overlap with the upper inner wall of the active air intake grille, further increasing the difficulty of gas entering the active air intake grille. At the same time, the first hydraulic rod and the second hydraulic rod are both in an extreme extension state. Therefore, if a collision occurs at this time, the isolation plate, the connecting shell and the slide will all play a role in alleviating the impact force of the collision, and transmit the impact force to the first hydraulic rod and the second hydraulic rod, thereby further alleviating the impact force during the collision through the first hydraulic rod and the second hydraulic rod, thereby improving the safety of the device when in use.

At this time, the thermoelectric conversion module of the hydraulic energy conversion component 22 absorbs the high temperature of the brake pad and performs energy conversion, thereby driving the hydraulic drive module of the hydraulic energy conversion component 22, and the hydraulic drive module then drives the first hydraulic rod 24 and the transmission component 23 to operate, so that The isolation component 21 is pushed by the transmission component 23 to complete the sealing of the active air intake grille 12. At the same time, the operation of the first hydraulic rod 24 will also push the connecting component 25 and the sliding component 26 to flip at an angle in the active air intake grille 12. On the one hand, the changes in the isolation component 21, the connecting component 25 and the sliding component 26 can greatly reduce the gas entering the active air intake grille 12, thereby increasing the resistance of the airflow in front of the vehicle body when the vehicle body moves, increasing the difficulty of the vehicle body moving forward, and cooperating with the braking action to accelerate the stopping of the vehicle; on the other hand, if a collision occurs during the braking action, the first hydraulic rod 24 pushes the connecting component 25 and the sliding component 26 to slide out, thereby adding a buffer structure to the front of the electric vehicle 11, effectively providing additional buffer protection for the main driver and the co-driver, thereby improving the braking efficiency of the device and the protection effect on personnel in the event of a collision; The brake system 13 and the thermoelectric conversion module are not shown in the attached figure. They are existing automobile accessories and a device that can directly convert thermal energy into electrical energy. They belong to the existing technology and their specific structures are not shown in the figure.

[0023] In an embodiment of the present invention, the number of active air intake grilles 12 is two, and the two active air intake grilles 12 are both opened in front of the electric vehicle 11, the four brake systems 13 are respectively connected to the four wheels of the electric vehicle 11, the number of inclined slots 14 is two, and the two inclined slots 14 are both opened above the electric vehicle 11, and the two inclined slots 14 are respectively connected to the two active air intake grilles 12, the hydraulic energy conversion component 22 includes a thermoelectric conversion module and a hydraulic drive module, the hydraulic energy conversion component 22 is respectively fixedly connected to the first hydraulic rod 24 and the transmission component 23, the transmission component 23 is overlapped with the isolation component 21, the top of the transmission component 23 is fixedly connected to the connecting component 25, the sliding component 26 is slidably connected in the connecting component 25, and the two sealing components 27 are respectively connected to the two ends of the isolation component 21. Side overlap, through the design of the transmission component 23 and the isolation component 21, when braking, the hydraulic energy conversion component 22 drives the first hydraulic rod 24 and the second hydraulic rod 231 to operate. When the second hydraulic rod 231 operates, it will push the gear plate 233 forward. As the gear plate 233 moves, the second gear 215 will rotate synchronously and drive one of the first gears 214 to rotate. When the second hydraulic rod 231 moves to the extreme position, the first gear 214 and the second gear 215 are both rotated ninety degrees, so that the two adjacent isolation plates 213 are in an overlapping state, thereby blocking outside air from entering the active air intake grille 12. In this way, it is more difficult for outside air to enter the active air intake grille 12 when the vehicle brakes, and the contact area between the front of the vehicle and the air in front is increased, providing an auxiliary effect for the vehicle's braking action.

[0024] The isolation assembly 21 is snapped onto the upper and lower inner walls of the active air intake grille 12. The hydraulic energy conversion assembly 22 is fixedly connected to the active air intake grille 12. The thermoelectric conversion module that constitutes the hydraulic energy conversion assembly 22 is connected to the brake system 13. The hydraulic drive module that constitutes the hydraulic energy conversion assembly 22 is respectively connected to the first hydraulic rod 24 and the transmission assembly 23. The connecting assembly 25 is fixedly connected to the active air intake grille 12. The hydraulic energy conversion assembly 22 is fixedly connected to the connection between the active air intake grille 12 and the inclined slot 14. Through the design of the connecting assembly 25 and the sliding assembly 26, as the first hydraulic rod 24 operates, the slide 261 drives the connecting shell 251 to rotate at an angle, causing the connecting shell 251 to rotate along the second rotator 253. During the flipping process, the limit block 263 slides within the limit slot 262, ensuring that the docking sleeve 266 always remains horizontal and connected to the first hydraulic rod 24. When the first hydraulic rod 24 moves to the extreme position, the slide plate 261 will overlap with the upper inner wall of the active air intake grille 12, further increasing the difficulty of gas entering the active air intake grille 12. At the same time, the first hydraulic rod 24 and the second hydraulic rod 231 are both in the extreme extension state. Therefore, if a collision occurs at this time, the isolation plate 213, the connecting shell 251 and the slide plate 261 will all play a role in alleviating the impact force of the collision and transmit the impact force to the first hydraulic rod 24 and the second hydraulic rod 231, thereby further alleviating the impact force during the collision through the first hydraulic rod 24 and the second hydraulic rod 231, thereby improving the safety of the device when in use.

[0025] In an embodiment of the present invention, the isolation component 21 includes a connecting sleeve 211, and the number of the connecting sleeves 211 is several. The two connecting sleeves 211 located in the same vertical direction are sleeved with the same connecting rod 212. The connecting rod 212 is fixedly connected to two isolation plates 213. The two adjacent isolation plates 213 overlap each other. The connecting rod 212 is fixedly connected to a first gear 214. The two adjacent first gears 214 are meshed with each other, and one of the first gears 214 is meshed with the second gear 215. The lower part of the second gear 215 is fixedly connected to a first rotator 216. The second gear 215 is meshed with the transmission component 23, and the lower part of the first rotator 216 is clamped. Below the inner wall of the active air intake grille 12, the upper connecting sleeve 211 and the lower connecting sleeve 211 are respectively clamped on the upper and lower inner walls of the active air intake grille 12. By designing sealing blocks 271 on both sides of the isolation sheet 213 on both sides, and contacting the isolation sheet 213 through the arc groove 272 of the sealing block 271, when the second hydraulic rod 231 is in operation, the gap between the isolation sheet 213 and the active air intake grille 12 will be filled by the sealing block 271, reducing the gas from gradually entering the active air intake grille 12 along the gap between the isolation sheet 213 and the active air intake grille 12, thereby improving the sealing effect of the active air intake grille 12 during braking.

[0026] As another embodiment of the present invention, the transmission assembly 23 includes a second hydraulic rod 231, one end of the second hydraulic rod 231 is fixedly connected to a connecting block 232, the other side of the connecting block 232 is fixedly connected to a tooth plate 233, the outer side of the second hydraulic rod 231 is fixedly connected to a mounting block 234, the second hydraulic rod 231 is fixedly connected to the hydraulic energy conversion assembly 22, the mounting block 234 is fixedly connected to the lower part of the inner wall of the active air intake grille 12, the tooth plate 233 is meshed with the second gear 215, the connecting assembly 25 includes a connecting shell 251, a groove 252 is opened at the bottom of the connecting shell 251, a second rotator 253 is clamped in the groove 252, and the second The rotator 253 is fixedly connected to the outside with a fixed block 254, and a slide groove 255 is provided above the connecting shell 251. The slide groove 255 and the connecting shell 251 are both arc-shaped. The sliding assembly 26 is slidably connected in the slide groove 255 above the connecting shell 251. The first rotator 216 and the second rotator 253 are both composed of bearings and rotating shafts. The fixed block 254 is fixedly connected above the mounting block 234. By adopting an arc-shaped design for both the connecting shell 251 and the slide plate 261, the arc-shaped design can change the moving direction of part of the splashing objects in the event of a collision, thereby preventing the splashing objects from directly hitting the interior of the electric car 11, thereby ensuring the safety of the driver.

[0027] As another embodiment of the present invention, the sliding assembly 26 includes a slide plate 261, a limiting groove 262 is provided on one side of the slide plate 261, a limiting block 263 is slidably connected in the limiting groove 262, and two sleeves 264 are externally clamped on the limiting block 263, and the same rotating rod 265 is sleeved in the two sleeves 264. The rotating rod 265 is outer-connected with a docking sleeve 266, and one side of the docking sleeve 266 is fixedly connected to the first hydraulic rod 24. The slide plate 261 is arc-shaped, and the slide plate 261 is slidably connected in the slide groove 255. The sealing assembly 27 includes two sealing blocks 271, and an arc groove 272 is provided on one side of the two sealing blocks 271.

The sealing block 271 is overlapped with one side of the isolation plate 213 through the arc groove 272. By providing a limiting groove 262 outside the slide plate 261 and connecting the limiting block 263 and the rotating rod 265 to the first hydraulic rod 24 through the limiting groove 262, it is ensured that the slide plate 261 will not get stuck when sliding in the connecting shell 251, and that the extension of the first hydraulic rod 24 can stably drive the slide plate 261 to slide in the connecting shell 251.

[0028] Working Principle: This embodiment provides a hydraulic transmission mechanism for an electric vehicle. When in use, the device must be used in conjunction with the electric vehicle 11. After the brake system 13 completes the braking action, the brake pads will emit high temperature. At this time, the thermoelectric conversion module in the hydraulic energy conversion assembly 22 will absorb the high temperature of the brake pads and convert it into energy, thereby driving the hydraulic drive module of the hydraulic energy conversion assembly 22. The hydraulic drive module then drives the first hydraulic rod 24 and the transmission assembly 23 to operate, so that the isolation assembly 21 is pushed by the transmission assembly 23, thereby completing the sealing of the active air intake grille 12. At the same time, the operation of the first hydraulic rod 24 will also push the connecting assembly 25 and the sliding assembly 26 to flip the angle within the active air intake grille 12. When braking, the hydraulic energy conversion assembly 22 drives the first hydraulic rod 24 and the second hydraulic rod 231 to operate. When the second hydraulic rod 231 operates, it pushes the toothed plate 233 forward. As the toothed plate 233 moves, the second gear 215 rotates synchronously, and during the rotation process, it drives one of the first gears 214 to rotate. When the second hydraulic rod 231 moves to the extreme position, the first gear 214 and the second gear 215 both rotate 90 degrees, so that the two adjacent isolation plates 213 are in an overlapping state, thereby blocking outside air from entering the active air intake grille 12; As the first hydraulic rod 24 operates, the slide 261 drives the connecting shell 251 to flip at an angle, causing the connecting shell 251 to flip along the second rotator 253. During the flipping process, the limit block 263 slides in the limit groove 262 to ensure that the docking sleeve 266 always remains horizontal and connected to the first hydraulic rod 24. When the first hydraulic rod 24 moves to the extreme position, the slide 261 overlaps the upper part of the inner wall of the active air intake grille 12, further increasing the difficulty of gas entering the active air intake grille 12. At the same time, the first hydraulic rod 24 and the second hydraulic rod 231 are both in the extreme extension state. Therefore, if a collision occurs at this time, the isolation piece 213, the connecting shell 251 and the slide 261 will all play a role in alleviating the impact force of the collision and transmit the impact force to the first hydraulic rod 24 and the second hydraulic rod 231. When the braking action is stopped after use, the first hydraulic rod 24 and the second hydraulic rod 231 are reset, and the movement of the tooth plate 233 will drive the first gear 214 to reset through the second gear 215, so that the two adjacent isolation plates 213 no longer contact each other. At this time, the outside air will enter the active air intake grille 12 along the gap between the isolation plates 213 and be discharged along the inclined slot 14.

Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes.
