Technical Field
The invention relates to the technical field of high-voltage control boxes, in particular to a buffer device of a high-voltage control box and an installation method of the buffer device.
Background
The contactor in the high-voltage control box can emit contact noise of about 60dB in the on-off process. In order to reduce the noise, a cushion pad is usually added at the position of the mounting foot of the high-voltage control box, so that a noise path when the contactor is opened and closed is isolated by the soft and elastic cushion pad, and finally, a user in the vehicle can obtain better sound feeling.
The bottom mounting feet, to which the cushion is usually added, are disposed at the edge of the high-pressure control box, as shown in fig. 1 (B) and 2 (B), and the mounting feet have an opening for convenient cushion mounting. When the high-voltage control box receives impact load in a certain designated direction, only half of the mounting feet need to bear all impact force due to the existence of the notches on the mounting feet; for example, when the high-pressure control box receives an impact from the side, the cushion pads in the two mounting feet on the side receiving the impact are offset to the notch positions without acting to receive the impact. This results in the mounting feet being prone to breakage in the event of a heavy high voltage control box, and further requires additional sufficient reinforcement design for the mounting feet to increase the volume and mass of the high voltage control box.
After the buffer pad is brought into the mounting foot of the high-voltage control box, the first-order mode of the high-voltage control box is smaller, resonance is easy to occur under the action of low-frequency excitation load, and the low-frequency load usually has larger energy; the mounting feet filled with the buffer cushion are provided with gaps, so that resonance effect can be increased, parts in the high-voltage control box have extremely high fatigue fracture risk and bolt electric connection moment attenuation risk in the random vibration process, the electric connection moment attenuation further causes thermal failure risk, and the low-voltage harness plug-in has certain loosening risk.

Detailed Description
The following description of the embodiments of the present invention will clearly and fully describe the technical aspects of the embodiments of the present invention, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, are intended to fall within the scope of the present invention.
Example 1
As shown in fig. 1, in combination with fig. 2, 3, 5 and 6, a buffer device for a high voltage control box of the present invention includes a first gasket 41, an intermediate body 42 and a second gasket 43.
The high-voltage control box is generally provided with a mounting foot 1 at the side edge, the mounting foot 1 is actually a plate with a through hole 101 formed therein, the mounting foot 1 is generally fixedly connected to a beam 2 in a mounting environment through a bolt 3, and the bolt 3 passes through the through hole 101 and is screwed with a screw hole on the beam 2.
As described in the background art, the current high voltage control box mounting pin 1 is provided with a notch on the side, because the current high voltage control box mounting pin 1 is a cushion pad with larger upper and lower ends and thinner middle part, the notch on the side of the mounting pin 1 can conveniently clamp the cushion pad into the through hole 101 of the mounting pin 1.
However, in this embodiment, the side of the mounting leg 1 is not opened, so that not only the strength of the mounting leg 1 itself can be improved, but also the problem that the cushion pad in the mounting leg 1 can deviate to the notch position and cannot bear the impact force when the high-voltage control box is impacted in the lateral direction can be avoided. However, although the mounting feet 1 with notches on the sides are generally used in the field of high-voltage control boxes, in other fields, the mounting feet 1 without openings are also a very common means; however, in general, other fields do not use such a cushion structure, and the reason for this is that the contactor in the high voltage control box described in the background art can generate contact noise of about 60dB during the on-off process, so that the cushion needs to be used for reducing the noise, and in order to mount such a cushion in the mounting leg 1, a notch needs to be formed on the side surface of the mounting leg 1.
Compared with the prior art, the difference of the embodiment is that: firstly, the mounting pin 1 which is not opened is adopted, so that adverse effects caused by the opening of the mounting pin 1 are solved, secondly, the buffer device 4 with an upper-lower split type structure is adopted, and even if the mounting pin 1 is not required to be opened, the buffer device 4 can be installed in the mounting pin 1; thirdly, the mounting leg 1 is not a flat plate, and in this embodiment, two end surfaces of the mounting leg 1 facing the beam 2 and away from the beam 2 are symmetrically provided with grooves 102, and the two grooves 102 are respectively communicated with two end parts of the through hole 101.
The buffer device 4 is sleeved on the bolt 3 and penetrates through the through hole 101, two ends of the buffer device 4 are respectively inserted into the two grooves 102, a gap 103 is reserved between the outer peripheral wall of the part of the buffer device 4 positioned in the groove 102 and the inner peripheral wall of the groove 102, and the buffer device 4 has elastic deformation capability and is pressed to elastically deform, and the outer peripheral wall of the buffer device 4 is tightly clung to the inner peripheral wall of the groove 102. The reason for adopting this design is that the applicant finds through long-term experimental study that the contactor in the high-voltage control box generates noise in the on-off process, because the high-voltage control box generates fine vibration in the on-off process, and because the cushion pad has elasticity, the mounting feet 1 and the bolts 3 penetrating the mounting feet inevitably generate fine horizontal displacement relative to the cross beam 2 due to the large load of the high-voltage control box, so that resonance is further increased and noise is generated.
Therefore, in the present embodiment, the upper and lower thicker ends of the buffer device 4 are disposed in the groove 102, and the buffer device 4 is deformed under pressure and closely contacts the inner wall of the groove 102 under the loading operation of the high-pressure control box, thereby restricting the horizontal displacement of the buffer device 4, thereby reducing the resonance effect and eliminating the noise to some extent.
Specifically, the first washer 41 is disposed in the recess 102 remote from the cross beam 2. A gap 103 is formed between the outer peripheral wall of the first gasket 41 or the second gasket 43 and the inner peripheral wall of the groove 102. In the present embodiment, the width of the gap 103 is 1mm in a state where the bolt 3 is not screwed.
The intermediate body 42 is inserted into the through hole 101. The intermediate body 42 is tightly filled between the inner wall of the through hole 101 and the bolt 3. The first gasket 41 is integrally formed with the intermediate body 42. The through hole 101 is tightly attached to the intermediate body 42 and is arranged in a round angle, so that the intermediate body 42 is prevented from being cut and torn during elastic displacement.
The second washer 43 is arranged in a recess 102 facing the cross beam 2. As the buffer device 4 with a split structure, a slot 401 is formed on the end surface of the second gasket 43 far away from the cross beam 2; the end of the intermediate body 42 remote from the first washer 41 is inserted into the slot 401.
The radial section of the first washer 41 and the second washer 43 along the bolt 3 is circular, the radial section of the groove 102 is also circular, and the axial leads of the first washer 41, the intermediate body 42, the second washer 43, the bolt 3, the groove 102 and the through hole 101 are overlapped, so that the contact surfaces of the mounting foot 1 and the buffer device 4 are made into cambered surfaces concentric with the buffer device 4, the first washer 41 or the second washer 43 can be fully clung to the whole inner peripheral wall of the groove 102 after being pressed and deformed so as to uniformly bear impact force, the mode of the high-pressure control box is improved to a certain extent, and the strength of the mounting foot 1 is also improved.
With the above design, when the bolt 3 is screwed, the first washer 41 is clamped between the nut of the bolt 3 and the bottom surface of the groove 102, the second washer 43 is clamped between the cross beam 2 and the bottom surface of the other groove 102, and the outer peripheral wall of the first washer 41 or the second washer 43 is tightly attached to the inner peripheral wall of the groove 102 after elastic deformation.
Based on the collaborative design of the mounting leg 1 mechanism and the buffer device 4 in the present embodiment, a mechanical impact comparison test is performed on the opening of the mounting leg 1 and the integrated buffer pad structure adopted in the present embodiment and the prior art, wherein the duration from the beginning to the end of the impact in the simulation practical application is preset to be 6ms, the maximum acceleration of the impact on the object in the simulation practical application is 50g, the results of the following table 1 are obtained, the meta-simulation situation is shown in fig. 7, wherein fig. 1 is the prior art, and fig. 2 is the present embodiment.

first, the first washer 41 and the intermediate body 42 are fitted into the mounting foot 1, the intermediate body 42 is inserted into the through hole 101 and the first washer 41 is placed in the groove 102 remote from the cross member 2.
Step two, the second gasket 43 is fitted into the mounting foot 1 and placed in the recess 102 facing the cross beam 2, the end of the intermediate body 42 being inserted into the slot 401 and the end of the sleeve 44 being inserted into the second gasket 43. The insertion groove 401 of the intermediate body 42 and the second gasket 43 have a small interference amount therebetween, so that the second gasket 43 does not fall out of the lower groove 102 due to its own weight.
And thirdly, placing the high-voltage control box on an assembly part of the beam 2 in an installation environment, sequentially penetrating the bolts 3 through the first gasket 41, the intermediate body 42 and the second gasket 43, screwing the beam 2, screwing the bolts 3, elastically deforming the first gasket 41 and the second gasket 43, and enabling the outer peripheral wall of the first gasket 41 or the second gasket 43 to be tightly attached to the inner peripheral wall of the groove 102. After the bolts 3 are screwed, the buffer device 4 receives a certain compression amount in the vertical direction, and simultaneously has a certain expansion amount in the horizontal direction, and at the moment, a certain prestress exists in the buffer device 4, so that the natural mode frequency of the whole equipment is improved to a certain extent.
Example two
On the basis of the first embodiment, as shown in fig. 1, in combination with fig. 4, a sleeve 44 is further included.
Wherein, the sleeve 44 is a metal cylinder, the sleeve 44 is sleeved on the bolt 3, and an outer flange 411 is arranged at the end of the sleeve 44 far away from the cross beam 2; the sleeve 44 is inserted into the intermediate body 42, two ends of the sleeve 44 are inserted into the two grooves 102, and the outer peripheral wall of the end of the sleeve 44 is closely attached to the inner peripheral wall of the first gasket 41 or the second gasket 43.
The bolt 3 is screwed and the nut is pressed against the end face of the outer flange 411, which is far away from the cross beam 2; the first gasket 41 is clamped between the outer flange 411 and the bottom surface of the groove 102.
The method for installing the buffer device of the high-voltage control box of the embodiment comprises the following steps:
first, the sleeve 44 is inserted into the first washer 41 and the intermediate body 42, and the first washer 41 and the intermediate body 42 are fitted into the mounting foot 1, the intermediate body 42 is inserted into the through hole 101, and the first washer 41 is placed in the groove 102 away from the cross member 2.
Step two, the second gasket 43 is fitted into the mounting foot 1 and placed in the recess 102 facing the cross beam 2, the end of the intermediate body 42 being inserted into the slot 401 and the end of the sleeve 44 being inserted into the second gasket 43.
And thirdly, placing the high-voltage control box on an assembly part of the mounting environment beam 2, penetrating the bolts 3 through the sleeves 44, screwing the beam 2, screwing the bolts 3, elastically deforming the first gasket 41 and the second gasket 43, and enabling the outer peripheral wall of the first gasket 41 or the second gasket 43 to be tightly attached to the inner peripheral wall of the groove 102.
Example III
The difference is that the width of the gap 103 is 0.3mm on the basis of the first embodiment.
Example IV
The difference is that the width of the gap 103 is 0mm on the basis of the first embodiment.
The mode improvement is advantageous in improving the performance of fatigue vibration, and the relief gap 103 does not significantly change noise without contact, but improves the natural mode. The opening of the installation foot 1 and the first-order natural mode of the integrated cushion model in the prior art are smaller, and the first-order natural mode of the installation foot 1 closed model adopted by the invention is larger. Meanwhile, the applicant finds that a gap 103 between the gasket and the inner peripheral wall of the groove 102 has strong correlation with the load of the high-pressure control box, and the gap 103 is excessively large, so that the displacement of the mounting angle 1 of the bottom shell is increased; and the gap 103 between the inner peripheral wall of the groove 102 and the gasket can be changed to be as close to 0 as possible, so that the first-order natural mode of the design model can be obviously improved, and the low-frequency fatigue resistance of the model can be improved.
To demonstrate the findings, the first order natural modes of the prior art and the first, third and fourth embodiments were compared to obtain the following table 2, and the natural mode element simulations of the prior art and the first and fourth embodiments are shown in fig. 8.
