Description

Technical Field

[0001] This invention relates to the field of electric vehicle controller technology, specifically to an anti-collision electric vehicle controller. Background Technology

[0002] An electric vehicle controller is a core control device used to control the starting, running, forward and backward movement, speed, and stopping of the electric vehicle motor, as well as other electronic components of the electric vehicle. It is like the brain of the electric vehicle and is an important component. Electric vehicles mainly include electric bicycles, electric two-wheeled motorcycles, electric tricycles, electric three-wheeled motorcycles, electric four-wheeled vehicles, and battery-powered vehicles. Electric vehicle controllers also have different performance and characteristics depending on the different vehicle models.

[0003] Existing anti-collision electric vehicle controllers can be referenced from Chinese Utility Model Patent No. CN218877502U, which discloses an anti-collision electric vehicle controller that "includes a controller body, with a shell sleeved on the outside of the controller body. Two anti-collision components are provided on the outer walls of the shell. Each anti-collision component includes a sleeve fixedly connected to the shell. A buffer rod is slidably connected to one end of the sleeve away from the shell, and an elastic ball head is fixedly connected to the other end of the buffer rod. When an external object collides with the controller body from one side, the object will first contact the elastic ball head. The elastic ball head can minimize damage to the external object and the controller body. Furthermore, the external force causes the buffer rod to retract inwards from the sleeve." This anti-collision electric vehicle controller, by fixing the shell to the controller body, ensures that when an external object collides with the controller body from one side, the object will first contact the elastic ball head. The elastic ball head can minimize damage to the external object and the controller body. Additionally, the external force causes the buffer rod to retract inwards from the sleeve, thereby reducing the impact force and improving the anti-collision effect of the controller body.

[0004] The aforementioned device, when in use, uses an elastic ball joint to minimize damage to external objects and the controller itself. Furthermore, the buffer rod retracts into the sleeve due to external force, thus mitigating the impact. However, the anti-collision effect of this device is insufficient in actual use. Since the impact force of a collision involving an electric vehicle is significant, relying solely on the elastic ball joint for anti-collision is inadequate. Insufficient protection can lead to damage to the controller upon impact, thus affecting its usability. Therefore, we propose an anti-collision electric vehicle controller to address these issues.

When not in use, the connecting plate can be stored inside the sealed cover, preventing it from corroding due to air contact and ensuring a smooth connection. It also avoids exposing the plate to the elements, thus preventing injury to handling personnel and improving the device's practicality. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-8 A collision-resistant electric vehicle controller includes a protective shell 1. The inner wall of the protective shell 1 houses the controller body 2. A square groove 3 is formed on the front of the protective shell 1. An air guide strip 4 is fixedly mounted on the inner wall of the square groove 3. A collision-resistant airbag 5 is fixedly mounted on the outer edge of the protective shell 1. A sealing cover 6 is fixedly mounted on the top of the protective shell 1. A cover plate 7 is fixedly installed on the top of the sealing cover 6. A blower 8 is fixedly mounted on the bottom of the inner wall of the sealing cover 6. A connection port 9 is fixedly mounted on the outer side of the blower 8. A connecting pipe 10 is fixedly mounted on the top of the connection port 9. A dual-axis motor 11 is fixedly mounted on the inner wall of the sealing cover 6. A lead screw 12 is fixedly mounted on the power output shaft of the dual-axis motor 11. The outer edge of the lead screw 12 is screwed... A slip ring 13 is connected to the airbag 5. A connecting plate 14 is fixedly mounted on the top of the slip ring 13. A limit plate 15 is fixedly mounted on the outer edge of the slip ring 13. A magnetic seat 18 is fixedly mounted on the inner wall of the airbag 5. One end of a spring 19 is fixedly mounted on the left side of the magnetic seat 18. A protective plate 20 is fixedly mounted on the other end of the spring 19. A magnetic plate 21 is fixedly mounted on the inner wall of the protective plate 20. A control valve 22 is fixedly mounted on the inner wall of the airbag 5. In the above structure, by using the connection port 9, the air discharged from the outlet of the blower 8 can be completely discharged to the inner cavity of the airbag 5 by the connecting pipe 10, so that leakage will not occur at will and the expansion of the inner cavity of the airbag 5 will not be affected.

[0022] In this structure, the end of the connecting pipe 10 furthest from the connection port 9 is fixedly installed on the inner wall of the anti-collision airbag 5. The inner wall of the sealing cover 6 has an installation hole. The outer diameter of the connecting pipe 10 is matched with the inner diameter of the installation hole. The connecting pipe 10 is installed on the inner wall of the installation hole. In this structure, by fixing the end of the connecting pipe 10 furthest from the connection port 9 to the inner wall of the anti-collision airbag 5, the air force generated by the blower 8 during operation can be discharged into the inner cavity of the anti-collision airbag 5 through the connecting pipe 10, thereby ensuring that the inner cavity of the anti-collision airbag 5 is in an inflated state. Thus, the anti-collision airbag 5, which is inflated by gas, can play a collision protection role for the device.

[0023] The inner wall of the sealing cover 6 is provided with a limiting groove 16. The width of the inner wall of the limiting groove 16 is adapted to the width of the limiting plate 15. The limiting plate 15 is slidably connected to the inner wall of the limiting groove 16. In the above structure, the limiting plate 15 is slidably connected to the inner wall of the limiting groove 16, so that the limiting groove 16 can limit the limiting plate 15. In turn, the limiting plate 15 can limit the slip ring 13, ensuring that the lead screw 12 cannot drive the slip ring 13 to rotate together when it rotates, but can only drive the slip ring 13 to move.

[0024] The inner wall of the sealing cover 6 has a through-hole 17, which corresponds to the position of the connecting plate 14. The top of the connecting plate 14 has a connecting hole. In the above structure, the corresponding position of the moving hole 17 and the connecting plate 14 allows the connecting plate 14 to move to the outside through the moving hole 17 when the slip ring 13 moves the connecting plate 14. This makes it convenient for the user to install and connect the connecting plate 14 to the electric vehicle body through the connecting hole. At the same time, when not in use, the connecting plate 14 can be stored in the inner wall of the sealing cover 6 to avoid contact with air and corrosion, and to prevent it from being exposed and causing injury to the handling personnel.

[0025] The inner wall of the slip ring 13 has a through hole, and the inner wall of the through hole has an internal thread. The lead screw 12 is threaded to the inner wall of the through hole. In the above structure, the lead screw 12 is threaded to the inner wall of the through hole, so that when the lead screw 12 rotates, it can drive the slip ring 13 and the connecting plate 14 to move through the internal thread of the inner wall of the through hole, so as to realize the storage and use of the connecting plate 14.

[0026] In this structure, the two power output shafts of the dual-axis motor 11 are respectively fixedly equipped with lead screws 12. Rotation holes are respectively opened on both sides of the inner wall of the sealing cover 6. The end of the lead screw 12 away from the dual-axis motor 11 is rotatably connected to the inner wall of the rotation hole. In this structure, by using the end of the lead screw 12 away from the dual-axis motor 11 to be rotatably connected to the inner wall of the rotation hole, the lead screw 12 can be limited during the rotation process, thereby ensuring that the lead screw 12 will not arbitrarily shift or flip during the rotation process. This avoids the lead screw 12 from arbitrarily shifting and swinging during rotation, which would affect the normal movement of the slip ring 13, thus improving the practicality of the device.

[0027] The outer side of the protective plate 20 is arc-shaped, and the arc-shaped protective plate 20 is adapted to the shape of the inner wall of the anti-collision airbag 5. The protective plate 20 is made of silicone. The anti-collision airbag 5 is distributed in a ring at the outer edge of the protective shell 1. In the above structure, by adapting the arc-shaped protective plate 20 to the shape of the inner wall of the anti-collision airbag 5, the anti-collision airbag 5 will not rub against the protective plate 20 when subjected to a heavy impact. At the same time, after contact, the force of the spring 19 can be used to reduce the impact force, thereby achieving the anti-collision effect.

[0028] In this structure, the magnetic poles of both the magnetic plate 21 and the magnetic base 18 are N poles. The number of magnetic base 18, spring 19, protective plate 20 and magnetic plate 21 are all several. These magnetic bases 18, springs 19, protective plates 20 and magnetic plates 21 are evenly and symmetrically arranged on the left and right sides of the inner wall of the anti-collision airbag 5. In this structure, the fact that the magnetic poles of both the magnetic plate 21 and the magnetic base 18 are N poles, and the principle of magnetic repulsion, can further reduce the force after impact, improve the anti-collision protection effect, and thus improve the service life of the controller body 2. At the same time, the evenly and symmetrically arranged magnetic bases 18, springs 19, protective plates 20 and magnetic plates 21 on the left and right sides of the inner wall of the anti-collision airbag 5 can provide protection for the controller body 2 from multiple angles and positions.

[0029] The device includes several air guide strips 4, which are evenly distributed on the inner wall of the square groove 3. The control valve 22 corresponds to the position of the square groove 3. A ventilation opening is provided on the outer side of the controller body 2. In the above structure, by utilizing the correspondence between the control valve 22 and the square groove 3, the control valve 22 can be opened and the blower 8 can be started when the device stops running. The air force is discharged through the anti-collision airbag 5 to the inner wall of the square groove 3, and then enters the inner wall of the ventilation opening to achieve the effect of heat dissipation for the controller body 2.

[0030] The inner wall of the sealing cover 6 is equipped with a storage battery, and the storage battery, the dual-shaft motor 11 and the blower 8 are all electrically connected. In the above structure, the storage battery, the dual-shaft motor 11 and the blower 8 are all electrically connected, so that electrical energy can be provided to the dual-shaft motor 11 and the blower 8, ensuring the normal operation of the dual-shaft motor 11 and the blower 8.

[0031] Working principle: When the device needs to be installed, the dual-axis motor 11 is first started to drive the lead screw 12 to rotate. The rotation of the lead screw 12 will drive the slip ring 13 and the connecting plate 14 to move. The connecting plate 14 will then pass through the moving hole 17 to the outside space, facilitating installation and connection between the user and the electric vehicle body through the connecting hole. When not in use, the connecting plate 14 can be stored inside the sealing cover 6 to prevent it from contacting air and causing corrosion, and to avoid injury to personnel handling it if exposed. After installation, during operation of the electric vehicle, the blower 8 can be started to discharge air through the connecting pipe 10 to the inner cavity of the anti-collision airbag 5, thereby... The anti-collision airbag 5 is in a constantly inflated state. In the event of a collision, the gas inside the anti-collision airbag 5 expands to improve the impact buffering effect. At the same time, with the help of the spring 19, the buffering effect of the device during the impact is further improved. When the impact force is too large, the magnetic plate 21 and the magnetic base 18 come into contact and generate a repulsive force, which further ensures the anti-collision performance. When the electric vehicle is stopped, the control valve 22 can be opened, and the blower 8 can be started at the same time to discharge the air through the anti-collision airbag 5 to the inner wall of the square groove 3, and then into the inner wall of the ventilation port to achieve the effect of heat dissipation for the controller body 2. During driving, the air can be cooled by the natural wind during driving.
