Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of capacitors, and particularly relates to an electric drive capacitor for new energy vehicles. Background Art
[0002] A capacitor is an element that stores electric charge and electrical energy (electric potential energy). Its principle is that a conductor is surrounded by another conductor, or the electric field lines emitted by a conductor all terminate at the conductor system of another conductor. Capacitors play an important role in circuits such as tuning, bypassing, coupling, and filtering.
[0003] The use of an electric drive capacitor in a new energy vehicle can help maintain a stable voltage output. However, the capacitor is relatively large in volume and has a certain mass. When installed using a common installation method, it cannot withstand the inertial impact during emergency braking of the new energy vehicle, and it is easy to cause damage to the internal structure of the capacitor body through the connecting column. Content of the Utility Model
[0004] In view of the problem of poor fixing performance of the capacitor with a common installation method in the prior art, the utility model proposes the following technical solutions:
[0005] An electric drive capacitor for a new energy vehicle, comprising: a capacitor body and an installation assembly. It is characterized in that the installation assembly includes an installation base plate and a connecting cylinder. An installation hole is penetrated through the surface of the installation base plate. The bottom of the connecting cylinder is threadedly sleeved with the installation base plate, and a plurality of limiting blocks are circumferentially arranged on the surface of the installation base plate.
[0006] By inserting the connecting cylinder, a plurality of limiting blocks are synchronously extruded. The displaced limiting blocks are attached to the surface of the capacitor body. After the installation assembly is fixed to the capacitor body by static friction, the capacitor body is fixed to an external installation position through the installation assembly, making the installation of the capacitor body more secure and preventing damage to the internal structure of the capacitor body due to displacement caused by external forces.
[0007] Preferably, an elastic ring is arranged between the limiting block and the installation base plate, and two ends of the elastic ring are respectively fixedly connected to the limiting block and the installation base plate.
[0008] Preferably, an elastic soft layer is arranged on one side of the limiting block, and the surface of the elastic soft layer is attached to the surface where it contacts the capacitor body.
[0009] The arranged elastic soft layer is extruded and deformed after being attached to the surface of the capacitor body, thereby increasing the static friction with the surface of the capacitor body and making the fixing strength between the installation assembly and the capacitor body higher.
[0010] As an optimization of the above technical solution, two rotating balls are rotatably inserted into the other surface of the limiting block, and one end of each rotating ball is in contact with the surface of the connecting cylinder.
[0011] The provided elastic ring can keep a certain distance between the limiting block and the capacitor body when the mounting base plate is inserted, avoiding sliding friction between the limiting block and the surface of the capacitor body, thereby affecting the insertion of the mounting base plate.
[0012] As an optimization of the above technical solution, the top of the limiting block is inclined, and the bottom of the connecting cylinder is in contact with the inclined surface and the normal surface of the limiting block in sequence.
[0013] Since the top of the limiting block is inclined, the connecting cylinder can automatically push the limiting block when inserted, without the need to use external devices for processing.
[0014] The beneficial effects of the present utility model are as follows:
[0015] 1. By inserting the connecting cylinder, multiple limiting blocks are synchronously squeezed. The displaced limiting blocks are in contact with the surface of the capacitor body. After fixing the mounting assembly and the capacitor body by using static friction, the capacitor body is fixed to the external mounting position through the mounting assembly, making the installation of the capacitor body more firm and preventing the internal structure of the capacitor body from being damaged due to displacement caused by external forces.
[0016] 2. The provided rotating balls can rotate along the surface of the connecting cylinder, converting the sliding friction between the connecting cylinder and the limiting block during vertical insertion and rotation of the connecting cylinder into rolling friction, avoiding the rotation of the connecting cylinder being blocked by the limiting block, and making the insertion of the connecting cylinder more convenient.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments and the drawings of the specification.
[0022] Embodiment
[0023] Figures 1 - 3 Among them, the electric drive capacitor for new energy vehicles includes: a capacitor body 10 and an installation component 20. The installation component 20 includes an installation base plate 21 and a connecting cylinder 22. The surface of the installation base plate 21 is penetrated with installation holes. The bottom of the connecting cylinder 22 is threadedly sleeved with the installation base plate 21. A plurality of limiting blocks 23 are circumferentially arranged on the surface of the installation base plate 21.
[0024] One side of the limiting block 23 is provided with an elastic soft layer 25, and the surface of the elastic soft layer 25 is in contact with the surface of the capacitor body 10.
[0025] By inserting the connecting cylinder 22, a plurality of limiting blocks 23 are synchronously extruded. The displaced limiting blocks 23 are in contact with the surface of the capacitor body 10. After the elastic soft layer 25 is extruded and deformed, the static friction force with the surface of the capacitor body 10 is increased. After the installation component 20 and the capacitor body 10 are fixed by using the static friction force, the capacitor body 10 is fixed to the external installation position through the installation component 20, so that the installation of the capacitor body 10 is more firm and will not cause damage to the internal structure of the capacitor body due to displacement caused by external forces.
[0026] In this technical solution, the parameters of the capacitor are:
[0027] Serial number Parameter name Parameter value 1 Flame retardant rating UL94-V0 2 Insulation resistance Greater than 1000 MΩ 3 Withstand voltage Max 4000 Vdc 4 Weather resistance 40 / 105 / 56 5 Low self-inductance Less than 10 nH 6 Ripple resistance Greater than 150 A 7 Pulse voltage withstand 1.5UN
[0028] An elastic ring 24 is arranged between the limiting block 23 and the installation base plate 21, and both ends of the elastic ring 24 are fixedly connected to the limiting block 23 and the installation base plate 21 respectively.
[0029] The arranged elastic ring 24 can keep a certain distance between the limiting block 23 and the capacitor body 10 when the installation base plate 21 is inserted, avoiding sliding friction between the limiting block 23 and the surface of the capacitor body 10, thereby affecting the insertion of the installation base plate 21.
[0030] Figures 2 - 3 Among them, two groups of rotating balls 26 are rotatably inserted on the other side surface of the limiting block 23, and one end of the rotating ball 26 is in contact with the surface of the connecting cylinder 22.
[0031] The arranged rotating balls 26 can rotate along the surface of the connecting cylinder 22, converting the sliding friction between the connecting cylinder 22 and the limiting block 23 during the vertical insertion and rotation of the connecting cylinder 22 into rolling friction, avoiding the rotation of the connecting cylinder 22 being blocked by the limiting block 23, and making the insertion of the connecting cylinder 22 more convenient.
[0032] Figures 2 - 3 Among them, the top of the limiting block 23 is inclined, and the bottom of the connecting cylinder 22 is in contact with the inclined surface and the normal surface of the limiting block 23 in sequence.
[0033] Since the top of the limiting block 23 is inclined, the connecting cylinder 22 can automatically push the limiting block 23 when being inserted, without the need to use external devices for processing.
[0034] Working principle: Before installing the capacitor body 10, first insert the mounting base plate 21 from the bottom of the capacitor body 10, and then insert the connecting cylinder 22 from the top of the capacitor body 10. During the insertion process of the connecting cylinder 22, since the top of the limiting block 23 is inclined, the bottom of the connecting cylinder 22 contacts the inclined surfaces of multiple limiting blocks 23. The multiple limiting blocks 23 are synchronously pushed by the connecting cylinder 22 and move towards the center of the capacitor body 10, and the corresponding elastic soft layer 25 is compressed and deformed accordingly. After the connecting cylinder 22 contacts the normal surface of the limiting block 23, the rotating ball 26 rotates on the inner surface of the connecting cylinder 22. The rotating ball 26 converts the sliding friction between the limiting block 23 and the connecting cylinder 22 into rolling friction, facilitating the insertion of the connecting cylinder 22. After the connecting cylinder 22 is inserted to the bottom of the mounting base plate 21, rotate the connecting cylinder 22 to fix it to the mounting base plate 21 by threading. At this time, the rotating ball 26 rotates on the inner surface of the connecting cylinder 22, converting the sliding friction between the limiting block 23 and the connecting cylinder 22 into rolling friction, and preventing the limiting block 23 from hindering the rotation of the connecting cylinder 22.
[0035] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
