Description

Technical Field

[0001] This invention relates to the field of new energy vehicle motor technology, and in particular to a protective device for new energy vehicle motors. Background Art

[0002] New energy vehicles refer to automobiles that use unconventional vehicle fuels as their power source (or use conventional vehicle fuels but employ new onboard power devices), integrating advanced technologies in vehicle power control and drive, resulting in vehicles with advanced technical principles and new technologies and structures. New energy vehicles include pure electric vehicles, range-extended electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, and hydrogen engine vehicles.

[0003] Electric motors are widely used in new energy vehicles. However, existing electric motors lack protective measures during installation and use. In particular, when a vehicle is involved in a collision, the inertia prevents braking and reduces the damage caused by the impact, which is detrimental to the safety of the vehicle motor and the user. Therefore, we propose a protective device for electric motors in new energy vehicles. Summary of the Invention

[0004] The present invention proposes a protective device for the motor of a new energy vehicle, which solves the problem that existing vehicles lack impact mitigation measures in the event of a collision, which is detrimental to the safety of the motor and the user.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A protective device for a new energy vehicle motor includes two mounting brackets. A motor is mounted on the top of the mounting brackets, and air duct fins are provided on the outside of the motor. A base plate is provided between the two mounting brackets. A fixing frame is hinged to the top side of the base plate. A blowing assembly is provided on one side of the fixing frame. An adjustment assembly is provided below the motor. A vertical plate is provided at one end of the adjustment assembly. A snap-fit ​​assembly is provided between the vertical plate and the fixing frame.

[0007] Below the snap-fit ​​assembly is a proximity switch that is fixedly connected to the vertical plate. On both sides of the proximity switch are guide rods that movably penetrate the vertical plate. One end of the guide rod is fixedly connected to a proximity switch trigger block. An elastic band is provided between the proximity switch trigger block and the motor. The proximity switch is connected to a PLC through a wire, and the PLC is located at the top of the fixed frame.

[0008] Preferably, the blower assembly includes a servo motor fixedly connected to a fixed frame, the output shaft of the servo motor is fixedly connected to a fan blade, the fixed frame has multiple air inlets on the side near the servo motor, and the fixed frame has multiple air outlets on the right side.

[0009] Preferably, the adjustment assembly includes a positioning plate fixedly connected to the base plate, two screws are rotatably provided inside the positioning plate, one end of the screws is provided with an operating component, and a threaded tube is threaded onto the outside of the screws, one end of the threaded tube being fixedly connected to the vertical plate.

[0010] Preferably, the operating component includes pulleys fixedly connected to the screw, and belts are sleeved on the outside of the two pulleys.

[0011] Preferably, the snap-fit ​​assembly includes a sliding block slidably disposed on the fixed frame, a crossbar fixedly connected to one side of the sliding block, limit blocks fixedly connected to both ends of the crossbar, and a cross plate fixedly connected to the vertical plate above the limit blocks.

[0012] Preferably, a sliding hole is provided on the left side of the fixed frame, and a sliding block is slidably disposed in the sliding hole.

[0013] Preferably, the vertical plate has two guide holes, and a guide rod passes through the guide holes, with a baffle fixedly connected to the left end of the guide rod.

[0014] Preferably, the bottom of the motor is fixedly connected to a base, and the base is fixedly connected to the mounting bracket by bolts, and the elastic band is fixedly connected to the base.

[0017] Compared with existing technologies, the beneficial effects of this invention are:

[0018] 1. The present invention uses a structure including a fixed frame, a blower assembly, and a snap-fit ​​assembly. The snap-fit ​​assembly makes it easy to fix the fixed frame, which facilitates the blower assembly on the fixed frame to blow air to cool the motor. The multiple air duct fins on the outside of the motor facilitate airflow, thereby accelerating the heat dissipation efficiency.

[0019] 2. The present invention uses a structure including a fixed frame, a vertical plate, an adjustment component, an operating component, a proximity switch, a proximity switch trigger block, an elastic band, and a PLC. The proximity switch trigger block will move closer to the proximity switch under inertia, so the proximity switch will transmit a signal to the PLC, and the PLC will send a braking signal to make the vehicle brake actively, thereby reducing the damage caused by the impact and improving the safety of the motor and the user.

[0020] In summary, this solution features a simple structure and novel design. It not only facilitates airflow for motor cooling and accelerates heat dissipation efficiency, but also provides external protection for the motor and assists in vehicle active braking, thereby mitigating the damage caused by impacts and contributing to the safety of both the motor and the user.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0031] Reference Figure 1-7A protective device for a new energy vehicle motor includes two mounting brackets 1. A motor 3 is mounted on the top of the mounting bracket 1. Air duct fins 4 are mounted on the outside of the motor 3. A base plate 5 is located between the two mounting brackets 1. A fixing frame 6 is hinged to one side of the top of the base plate 5. A blowing component is located on one side of the fixing frame 6. An adjustment component is located below the motor 3. A vertical plate 16 is located at one end of the adjustment component. A snap-fit ​​component is located between the vertical plate 16 and the fixing frame 6.

[0032] Below the snap-fit ​​assembly is a proximity switch 18 fixedly connected to the vertical plate 16. On both sides of the proximity switch 18 are guide rods 19 that move through the vertical plate 16. One end of the guide rod 19 is fixedly connected to a proximity switch trigger block 20. An elastic band 21 is provided between the proximity switch trigger block 20 and the motor 3. The proximity switch 18 is connected to a PLC 22 through wires, and the PLC 22 is set at the top of the fixed frame 6.

[0033] like Figure 1 As shown, the air blowing assembly includes a servo motor 7 fixedly connected to a fixed frame 6. The output shaft of the servo motor 7 is fixedly connected to a fan blade 8. The fixed frame 6 has multiple air inlets on the side near the servo motor 7 and multiple air outlets on the right side. The servo motor 7 drives the fan blade 8 to blow air, and the air blows towards the motor 3 to improve the heat dissipation efficiency.

[0034] like Figure 7 As shown, the adjustment assembly includes a positioning plate 12 fixedly connected to the base plate 5. The positioning plate 12 has two screws 13 rotatably mounted inside. One end of each screw 13 is equipped with an operating component. The screw 13 is threaded with a threaded tube 15. One end of the threaded tube 15 is fixedly connected to the vertical plate 16. Rotating the screw 13 can drive the threaded tube 15 to move, and the threaded tube 15 in turn drives the vertical plate 16 to move.

[0035] like Figure 7 As shown, the operating component includes pulleys 14 fixedly connected to the screw 13. Belts are fitted around the two pulleys 14. Manual operation of the belts can simultaneously drive the two pulleys 14 to rotate, thereby causing the screw 13 to rotate simultaneously.

[0036] like Figure 1 As shown, the snap-fit ​​assembly includes a sliding block 9 that is slidably disposed on the fixed frame 6. A horizontal bar 10 is fixedly connected to one side of the sliding block 9. Limiting blocks 11 are fixedly connected to both ends of the horizontal bar 10. A horizontal plate 17 is fixedly connected to the vertical plate 16 above the limiting block 11. The horizontal plate 17 limits the limiting block 11, which makes it easier to fix the fixed frame 6.

[0037] like Figure 5 As shown, a sliding hole is provided on the left side of the fixed frame 6, and the sliding block 9 is slidably disposed in the sliding hole.

[0038] like Figure 5As shown, two guide holes are provided on the vertical plate 16, and the guide rod 19 passes through the guide holes. A baffle is fixedly connected to the left end of the guide rod 19.

[0039] like Figure 1 As shown, the bottom of the motor 3 is fixedly connected to the base 2, and the base 2 is fixedly connected to the mounting bracket 1 by bolts. The elastic band 21 is fixedly connected to the base 2.

[0040] like Figure 4 As shown, the proximity switch trigger block 20 has an n-shaped structure, and a ball is movably embedded in the bottom of the proximity switch trigger block 20.

[0041] like Figure 4 As shown, the mounting bracket 1 has multiple bolt holes arranged in an array, and the bolt holes are fixedly connected to the vehicle chassis by bolts.

[0042] Detailed working principle: Motor 3 is mounted on mounting bracket 1 via base 2 using bolts. During use, fixing frame 6 covers the outside of motor 3 for protection. Servo motor 7 drives fan blade 8 to blow air, and the airflow passes through the air duct fins 4 outside motor 3 to improve heat dissipation efficiency. Horizontal plate 17 limits the limit block 11, which makes it easy to fix the fixing frame 6. When it is necessary to open the fixing frame 6, first manually slide the limit block 11 to one side, so that the limit block 11 is misaligned with the horizontal plate 17. At this time, the fixing frame 6 can be rotated to open it.

[0043] When a vehicle collision occurs, the proximity switch trigger block 20 slides towards the proximity switch 18 due to inertia. When the proximity switch trigger block 20 approaches the proximity switch 18, the proximity switch 18 transmits a signal to the PLC 22, which then sends a braking signal to activate the vehicle's automatic braking. This mitigates the impact damage and improves the safety of the motor 3 and the user. The elastic band 21 helps the proximity switch trigger block 20 to reset. When disassembly or assembly is required, the belt can be manually operated to simultaneously rotate both pulleys 14, which in turn rotate the screw 13. The rotation of the screw 13 moves the threaded tube 15, which in turn moves the vertical plate 16, moving it away from the motor 3 for easier disassembly and maintenance.

[0044] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
