Description
Technical Field
[0001] This utility model belongs to the field of electric vehicle capacitor technology, and in particular relates to a fixing device for electric vehicle capacitors. Background Technology
[0002] Electric vehicle capacitors are electronic components that store electrical energy. Through their rapid charging and discharging characteristics, they assist the battery in providing instantaneous high current to the motor, relieving battery load, improving vehicle acceleration performance and energy recovery efficiency, and are an important component of the electric vehicle's power system.
[0003] For example, Chinese patent CN211555689U discloses a fixing and protection device for an electric vehicle capacitor. The fixing and protection device for an electric vehicle capacitor includes a base, with first sliding rods installed at the four corners of the top surface of the base. The four first sliding rods are slidably connected to the inner sidewalls of the first vertical cylinders. Multiple first springs are installed on the top surface of the base. The top ends of the four first vertical cylinders are fixedly connected to the bottom surface of a protective box. A fan is installed on the sidewall of the protective box, and an air outlet is provided on the sidewall. A fixing plate is installed on the inner bottom surface of the protective box. The fixing plate has four sliding grooves, which are slidably connected to the two ends of a front fixing block and the two ends of a rear fixing block. The two sidewalls of the front fixing block are fixedly installed to the two sidewalls of the rear fixing block by two bolts. The fixing and protection device for an electric vehicle capacitor provided by this utility model has functions such as shock absorption and cooling.
[0004] The aforementioned patent has the following problems:
[0005] This patent has some drawbacks in its use, such as: the device absorbs vibration solely through the elastic deformation of a spring; after absorbing vibration energy, the spring releases energy through repeated elastic deformation, leading to continuous oscillation and poor shock absorption; furthermore, the device is complex and time-consuming to install the capacitor, and difficult to disassemble without tools. Therefore, we propose a capacitor fixing device for electric vehicles. Utility Model Content
[0006] The purpose of this invention is to provide a capacitor fixing device for electric vehicles to solve the problems mentioned in the background art.
[0007] In view of this, the present invention provides a capacitor fixing device for electric vehicles, including a base and a plurality of capacitors, and further comprising:
[0008] A fixed shell is provided above the base. The bottom of the fixed shell and the top of the base are provided with four sliding grooves. Sliding blocks are slidably installed in each of the eight sliding grooves. Two rotating columns are provided between the base and the sliding grooves. Two connecting rods are rotatably installed on each of the two rotating columns. The two ends of the four connecting rods are rotatably connected to the eight sliding blocks respectively.
[0009] Two sets of shock-absorbing components, both of which are located inside the base and are used to dampen the fixed shell.
[0010] The power chamber is located inside the fixed shell, and two sliding plates are slidably installed inside the power chamber. A plurality of capacitors are disposed between the two sliding plates.
[0011] A drive assembly, located within a fixed housing, is used to drive two sliding plates to slide.
[0012] In this technical solution, when it is necessary to fix several capacitors, the driving component can drive two sliding plates to slide and move closer to each other. Then the two sliding plates will fix the position of several capacitors. The base is fixed to the working location with bolts, which is convenient for fixing several capacitors. No tools are needed and the operation is simple. It can also protect several capacitors and ensure the stability of several capacitors during use.
[0013] When the fixed housing is vibrated, it will press down on the four sliding blocks. The four sliding blocks will then drive the four fixed blocks above to slide downwards. Through the shock absorption components, all eight sliding blocks will slide away from the fixed housing. The eight sliding blocks will then drive the four connecting rods to rotate. The two rotating columns will ensure the stability of the four connecting rods during rotation. The shock absorption components will also ensure that the vibration will not increase further, reduce the vibration experienced by the capacitor, and ensure the stability of the capacitor during use.
[0014] In the above technical solution, the shock absorption component further includes:
[0015] Two damping rods are provided, both of which are disposed between the base and the sliding groove. Fixed blocks are fixedly installed at both ends of the two damping rods. Four fixed blocks are fixedly installed on one side of the four sliding blocks respectively. Springs are sleeved on both damping rods, and the two ends of the two springs are fixedly connected to the four fixed blocks respectively.
[0016] In this technical solution, when the fixed shell is vibrated, it will press down on the four sliding blocks. The four sliding blocks will then drive the four fixed blocks above to slide downwards. At the same time, the four damping rods will be compressed and absorb vibrations, and the four springs will also be compressed and slowly contract. Then, all eight sliding blocks will slide away from the fixed shell, and each of the eight sliding blocks will drive the four connecting rods to rotate. The two rotating columns ensure the stability of the four connecting rods during rotation. Then, under the rebound force of the four springs, the damping rods can be reset, ensuring that the vibration will not increase further, reducing the vibration experienced by the capacitor, and ensuring the stability of the capacitor during use.
[0017] In the above technical solution, the driving component further includes:
[0018] A worm gear is rotatably mounted inside the power chamber. A threaded rod is fixedly mounted on one end of the worm gear. The threaded rod is located on one side of two sliding plates. One end of the threaded rod passes through the two sliding plates. The threaded rod has two sections of threads with opposite directions and is threadedly connected to the two sliding plates. A worm is meshed on one side of the worm gear. Both the worm and the threaded rod are rotatably connected to the power chamber.
[0019] In this technical solution, when it is necessary to fix several capacitors, the worm is rotated in the forward direction. The worm drives the worm wheel that meshes with it to rotate, and the worm wheel drives the threaded rod to rotate. Under the action of the thread, the two sliding plates slide and move closer to each other. Then, the two sliding plates will fix the position of several capacitors. Finally, the base is fixed to the working location with bolts. This makes it convenient to fix several capacitors without the need for tools. The operation is simple and can protect several capacitors, ensuring the stability of several capacitors during use.
[0020] In the above technical solution, a rubber sleeve is fixedly installed on the worm gear, and an operating disc is fixedly installed on the top end of the worm gear.
[0021] In this technical solution, a rubber sleeve is provided to ensure that the worm gear will not rotate when not in use, and an operating panel is provided to facilitate the rotation of the worm gear by the operator.
[0022] In the above technical solution, a guide rod is further fixedly installed inside the power cavity. The guide rod is located on one side of the two sliding plates, and one end of the guide rod passes through the two sliding plates, and the guide rod is slidably connected to the two sliding plates.
[0023] In this technical solution, it is ensured that the two sliding plates slide stably on the guide rod.
[0024] In the above technical solution, furthermore, several rubber pads are fixedly installed on both sliding plates, and the several rubber pads are in close contact with several capacitors respectively.
[0025] In this technical solution, several rubber pads are in close contact with several capacitors to ensure that the capacitors are not scratched when they are fixed.
[0026] In the above technical solution, a sealing plate is further rotatably installed on the top of the fixed shell.
[0027] In this technical solution, a sealing plate is installed to ensure that dust does not enter the capacitor.
[0028] The beneficial effects of this utility model are:
