[0002] With the booming development of the new energy vehicle industry, the performance requirements for key electronic components such as capacitors are becoming increasingly stringent.

[0003] As a core component of the electronic system of new energy vehicles, the stability and reliability of high ripple current withstand capacitors for new energy vehicles are directly related to the overall vehicle performance and safety. In the existing technology, the importance of shock absorption measures is often overlooked in the design and application of such capacitors. During operation, new energy vehicles are subjected to vibrations and impacts from various factors such as uneven road surfaces, vehicle acceleration, and braking. These vibrations and impacts can not only damage the physical structure of the capacitor but also affect its electrical performance, leading to a decrease in capacitor performance, a shortened lifespan, and even safety accidents, resulting in insufficient practicality. Therefore, it is necessary to redesign high ripple current withstand capacitors for new energy vehicles to address the above issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high ripple current withstand type capacitor for new energy vehicles.

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

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5A high ripple current withstand type new energy vehicle capacitor includes a capacitor body 1 and a mounting plate 2. The mounting plate 2 is fixedly mounted with a slide rod 3 via a moving groove. Two sliding sleeves 5 are slidably mounted on the outer wall of the slide rod 3 via a limiting mechanism. The limiting mechanism includes a limiting rod 4 fixedly installed inside the moving groove. The limiting rod 4 slides through the two sliding sleeves 5 and can limit the movement of the two sliding sleeves 5, so that the two sliding sleeves 5 can only move axially along the outer wall of the slide rod 3. Two buffer springs 6 are installed on the outer wall of the slide rod 3. The two ends of the two buffer springs 6 are elastically connected to the inner wall of the moving groove on the same side and the outer wall of the sliding sleeves 5, respectively. A first connecting frame 7 is fixedly installed on the upper surface of each of the two sliding sleeves 5. A second connecting frame 9 is rotatably connected to the inside of each of the two first connecting frames 7 via a connecting mechanism. The connecting mechanism includes a connecting plate 8 rotatably installed inside the first connecting frame 7. The end of the connecting plate 8 is rotatably connected to the inside of the second connecting frame 9. A placement plate 10 is fixedly installed on the upper surface of the two second connecting frames 9. The capacitor body 1 is slidably mounted on the upper surface of the placement plate 10.

[0023] Two damping spring telescopic rods 11 are fixedly installed on the upper surface of the mounting plate 2. The telescopic ends of the two damping spring telescopic rods 11 are fixedly connected to the bottom wall of the placement plate 10. Two fixing plates 12 are fixedly installed on the upper surface of the placement plate 10. Clamping plates 14 are fixedly installed inside the two fixing plates 12 through telescopic mechanisms. The telescopic mechanism includes an electric push rod 13 fixedly installed on the inner wall of the fixing plate 12. The telescopic end of the electric push rod 13 is fixedly connected to the outer wall of the clamping plate 14. Anti-slip pads 15 are fixedly installed on the inner walls of the two clamping plates 14. Both anti-slip pads 15 are made of rubber. Rubber material has good elasticity and softness, which allows it to form a closer contact between the surface and the object, thereby increasing friction and improving the coefficient of friction.

[0024] Two cooling fans 17 are fixedly mounted on the outer wall of the capacitor body 1 via mounting frames 16. Dustproof nets 18 are fixedly mounted on the outer walls of both mounting frames 16. A dustproof cover 19 is slidably mounted on the upper surface of the mounting plate 2. A glass 20 is fixedly mounted on the outer wall of the dustproof cover 19 through a mounting opening. Connecting plates 21 are fixedly mounted on both outer walls of the mounting plate 2. Support plates 22 are fixedly mounted on both outer walls of the dustproof cover 19. Fixing pins 23 are slidably installed through the outer walls of both support plates 22. Insertion holes that mate with the fixing pins 23 on the same side are opened on the outer walls of both connecting plates 21. A lever 24 is fixedly mounted on the end of each of the two fixing pins 23. The inner walls of both levers 24 are connected to the outer walls of the support plates 22 on the same side through a fixing mechanism. The fixing mechanism includes a fixing spring 25 installed on the outer wall of the fixing pin 23. The two ends of the fixing spring 25 are elastically connected to the inner walls of the levers 24 and the outer walls of the support plates 22, respectively.

[0025] In use, the capacitor body 1 is placed on the upper surface of the mounting plate 10. The extension and retraction of the two electric push rods 13 move the clamping plate 14, which in turn clamps and secures the capacitor body 1 using the anti-slip pad 15. This prevents the capacitor body 1 from loosening due to vehicle vibration. The anti-slip pad 15 increases the friction between itself and the outer wall of the capacitor body 1, thus improving the clamping stability. After the capacitor body 1 is installed and fixed, the dust cover 19 can be slidably installed on the upper surface of the mounting plate 2. The fixing spring 25 moves the fixing pin 23 into the socket, thereby completing the dust prevention... The dust cover 19 is fixed to the mounting plate 2. The dust cover 19 can protect the capacitor body 1, effectively block dust, keep the capacitor surface clean, thereby extending its service life and ensuring stable performance. At the same time, when it is necessary to disassemble the dust cover 19, the lever 24 can be moved to move the fixing pin 23 out of the socket, thereby releasing the fixation of the support plate 22. Then the dust cover 19 can be easily removed from the upper end of the mounting plate 2. When the dust cover 19 is protecting the capacitor body 1, the working status of the capacitor body 1 can be observed through the glass 20.

[0026] When the capacitor body 1 heats up during operation, it can be cooled by the cooling fan 17. The dustproof net 18 can cover and protect the dust at the ventilation port on one side of the capacitor body 1, preventing it from overheating and dust from affecting normal operation. When the capacitor body 1 vibrates under force, the force generated by the vibration can be transmitted to the two second connecting frames 9 through the placement plate 10. The force on the two second connecting frames 9 can be transmitted to the two first connecting frames 7 through the cooperation of the connecting plate 8. The force on the two first connecting frames 7 can drive the sliding sleeve 5 to slide on the outer wall of the sliding rod 3. When the two sliding sleeves 5 slide, they can compress the buffer spring 6 on the same side. Under the action of compression, the two buffer springs 6 can release elastic potential energy. The two damping spring telescopic rods 11 can buffer and absorb the released elastic potential energy. With the cooperation of the buffer spring 6 and the damping spring telescopic rod 11, the force can be better absorbed and dispersed, thereby achieving a better shock absorption effect.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
