A shock-absorbing pad applied to a high-voltage distribution box and a high-voltage distribution box

Abstract

This application discloses a shock-absorbing pad and a high-voltage distribution box for use in high-voltage distribution boxes, belonging to the technical field of high-voltage distribution boxes. It includes a connecting part, a first shock-absorbing part, and a second shock-absorbing part. The connecting part of this application is provided with a first through hole and a snap-fit ​​groove. The first through hole is used for the sleeve and bolt to pass through. The first and second shock-absorbing parts, at their ends away from the connecting part, are respectively provided with a first groove and a second groove, to provide more elastic clearance space for the connecting part in the direction of the first through hole, thereby improving the elastic shock-absorbing performance of the shock-absorbing pad. Simultaneously, the first and second shock-absorbing parts, at their ends away from the connecting part, are respectively provided with a first arc groove and a second arc groove. Under load, the arc-shaped groove structure can undergo combined bending and tensile deformation, resulting in more complex elastic deformation of the material along the arc direction, extending the deformation path, and increasing the length of impact energy distribution and transmission along the arc direction. This allows for the absorption of more elastic potential energy, thereby improving the shock absorption effect.

Detailed Implementation

[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0018] In a vehicle's battery module, high-voltage power distribution equipment such as BDU (Battery Disconnect Unit), PDU (Power Distribution Unit), and BMU (Battery Management Unit) are typically required to manage the power distribution of the battery.

[0019] Due to the fixed location requirements of high-voltage distribution boxes, high-voltage power distribution equipment is usually installed on vehicles with bolts to form a rigid connection. However, under the rigid connection of bolts, the vibration generated by the movement of the vehicle will be transmitted to the high-voltage distribution box through the bolts, which cannot meet the vibration requirements of the high-voltage distribution box operation. In fact, under long-term vibration transmission, it will affect the connection and contact performance between the electrical control devices in the high-voltage distribution box, as well as the tightness of the bolts, thus affecting the normal operation of the high-voltage power distribution equipment.

[0020] In view of this, embodiments of this application provide a shock-absorbing pad for use in high-voltage distribution boxes. Please refer to [link to relevant documentation]. Figures 1 to 7 , Figure 1 This is a first perspective view of a shock-absorbing pad applied to a high-voltage distribution box, provided in an embodiment of this application.

Figure 5 A second cross-sectional view of a shock-absorbing pad applied to a high-voltage distribution box provided in an embodiment of this application (with a first spherical groove and a second spherical groove added to the first cross-sectional view). Figure 6 The fourth perspective view of the shock-absorbing pad applied to the high-voltage distribution box provided in the embodiment of this application (the third perspective view is based on which a fourth through hole is added). Figure 7The third cross-sectional view (adding a fourth through hole to the second cross-sectional view) of the shock-absorbing pad for a high-voltage distribution box provided in the embodiments of this application includes a connecting part 10, a first shock-absorbing part 20, and a second shock-absorbing part 30. The connecting part 10 has a first through hole 11 and a snap-fit ​​groove 12. The snap-fit ​​groove 12 has a first abutment surface 121 and a second abutment surface 122 spaced apart. The first shock-absorbing part 20 is connected to the connecting part 10 and has a second through hole 21, a first groove 22, and a first arc groove 23. The second through hole 21 is linearly connected to the first through hole 11. The first groove 22 is located on the side of the first shock-absorbing pad away from the connecting part 10. The second shock absorber 30 is connected to the connecting part 10 and has a third through hole 31, a second groove 32 and a second arc groove 33. The third through hole 31 is linearly connected to the first through hole 11 and the second through hole 21. The second groove 32 is located on the side of the second shock absorber 30 away from the connecting part 10 and is connected to the third through hole 31. The second arc groove 33 is circumferentially spaced around the second groove 32 and the axis of the second arc groove 33 passes through the center of the circumference. The connecting portion 10 of this application is provided with a first through hole 11 and a snap-fit ​​groove 12. The first through hole 11 is used for the sleeve 50 and bolt to pass through. The first damping portion 20 and the second damping portion 30 are respectively provided with a first groove 22 and a second groove 32 at the ends away from the connecting portion 10, so as to provide more elastic clearance space for the connecting portion 10 in the extension direction of the first through hole 11 and improve the elastic damping performance of the damping pad. At the same time, the first damping portion 20 and the second damping portion 30 are respectively provided with a first arc groove 23 and a second arc groove 33 at the ends away from the connecting portion 10. The arc-shaped groove structure can undergo bending and tensile combined deformation under load, and the material generates more complex elastic deformation along the arc direction, extending the deformation path. The length of the impact energy distribution and transmission along the arc direction is increased, which can absorb more elastic potential energy and improve the damping effect. Specifically, the connecting portion, the first damping portion and the second damping portion in this application are integrally molded, and the material of the damping pad is rubber to improve the damping energy absorption performance.

[0021] In some embodiments, the connecting portion 10 of the shock-absorbing pad applied to the high-voltage distribution box provided in this application has a first through hole 11, which is a circular through hole for a bolt with a sleeve 50 inserted through it to pass through. The connecting portion 10 is cylindrical, and its outer wall has a snap-fit ​​groove 12. The snap-fit ​​groove 12 is used to snap and fix the shock-absorbing pad to the housing 40 of the high-voltage distribution box. Specifically, along the extending direction of the first through hole 11, the snap-fit ​​groove 12 has a first abutment surface 121 and abutment surface 122 that are spaced apart. The first abutment surface 121 and the second abutment surface 122 are connected to the connecting platform 41 on the housing 40 of the high-voltage distribution box, thereby realizing the connection between the shock-absorbing pad and the housing 40 of the high-voltage distribution box.

[0022] In some embodiments, the first damping part 20 is connected to the connecting part 10 and is disposed at one end of the first through hole 11 along its length, for abutting against the stop 52 on the sleeve 50. The first damping part 20 has a second through hole 21, which is linearly connected to the first through hole 11. Specifically, the second through hole 21 and the first through hole 11 are cylindrical holes with the same diameter and coincident axes, and the second through hole 21 and the first through hole 11 are through-through. The first damping part 20 has a first groove 22 on the side away from the connecting part 10, which is linearly connected to the second through hole 21. Specifically, the first groove 22 is a cylindrical groove, the axis of the first groove 22 coincides with the axis of the second through hole 21 and the first through hole 11, and the diameter of the first groove 22 is larger than the diameter of the second through hole 21. The second through hole 21 is connected to the first groove 22 through the bottom of the first groove 22. The first shock absorber 20 has a plurality of first arc grooves 23 on the side away from the connecting part 10. The opening of the first arc groove 23 faces the side of the first shock absorber 20 away from the connecting part 10. The plurality of first arc grooves 23 are spaced apart around the first groove 22 in the first circumferential direction X. The axis of the first arc groove 23 passes through the center of the first circumferential direction X.

[0023] In some embodiments, a first spherical groove 24 is provided between two adjacent first arc grooves 23. The curved surface design of the spherical groove allows the contact surface to undergo directional flexible deformation when subjected to pressure or vibration. In high-frequency vibration scenarios, the repeated deformation of the rubber in the groove can form an elastic buffer layer, which reduces vibration transmission efficiency by means of the characteristic that the deformation lags behind the load.

[0024] In some embodiments, the second damping part 30 is connected to the connecting part 10 and is disposed on the side of the connecting part 10 away from the first damping part 20, for abutting against the target equipment to be installed in the high-voltage distribution box, such as a new energy vehicle; the second damping part 30 has a third through hole 31, the third through hole 31, the second through hole 21 and the first through hole 11 are linearly connected, specifically, the third through hole 31, the second through hole 21 and the first through hole 11 are cylindrical holes with the same diameter and coincident axes, and the third through hole 31, the second through hole 21 and the first through hole 11 are connected through each other. The second damping part 30 has a second groove 32 on the side away from the connecting part 10, the second groove 32 is linearly connected to the third through hole 31, specifically, the second groove 32 is a cylindrical groove, the second groove 32 has the same diameter as the first groove 22, the diameter of the second groove 32 is larger than the diameter of the third through hole 31, and the third through hole 31 is connected to the second groove 32 through the bottom of the second groove 32. The second shock absorber 30 has a plurality of second arc grooves 33 on the side away from the connecting part 10. The opening of the second arc groove 33 faces the side of the connecting part 10 away from the first shock absorber 20. The plurality of second arc grooves 33 are spaced apart around the second groove 32 in the second circumferential direction Y. The axis of the second arc groove 33 passes through the center of the second circumferential direction Y.

[0025] In some embodiments, a second spherical groove 34 is provided between two adjacent second arc grooves 33. The curved surface design of the spherical groove allows the contact surface to undergo directional flexible deformation when subjected to pressure or vibration. In high-frequency vibration scenarios, the repeated deformation of the rubber in the groove can form an elastic buffer layer, which reduces vibration transmission efficiency by means of the characteristic that the deformation lags behind the load.

[0026] In some embodiments, the axes of the first circumferential direction X and the second circumferential direction Y coincide, and the snap-fit ​​groove 12 extends circumferentially along the first circumferential direction X and the second circumferential direction Y, and is connected end to end to form an annular snap-fit ​​groove 12, so as to increase the area of ​​the first contact surface 121 and the second contact surface 122 and improve the stability of the shock-absorbing pad connection; at the same time, the annular snap-fit ​​groove 12 is arranged around the circumference of the shock-absorbing pad, so that the circumferential force is more uniform when the shock-absorbing pad is connected to the housing 40 of the high-voltage distribution box, thereby improving the stability of the connection between the shock-absorbing pad and the housing 40 of the high-voltage distribution box.

[0027] In some embodiments, when the lengths of the first damping part 20 and the second damping part 30 are different due to different design scenarios along the extension direction of the first through hole 11, and when the depths of the first groove 22 or the second groove 32 are different, resulting in directional requirements for the installation of the first damping part 20 and the second damping part 30, the connecting part 10 of this application is provided with a pointing member 13, which faces the first damping part 20 or the second damping part 30, to assist installers in distinguishing between the two parts, improve the accuracy of installation, and reduce the rework rate.

[0028] In some embodiments, the connecting part 10 has a fourth through hole 14, which communicates with the first through hole 11, and the extending direction of the fourth through hole 14 intersects the extending direction of the first through hole 11. Specifically, the fourth through hole 14 is a cylindrical hole with smooth edges and uniform deformation capacity, which can effectively reduce stress concentration, adjust structural stiffness, absorb vibration energy, and improve vibration damping performance. Further, the axes of the first circumferential direction X and the second circumferential direction Y coincide, and multiple fourth through holes 14 are provided, which are spaced apart along the circumferential directions of the first circumferential direction X and the second circumferential direction Y.

[0029] Understandably, the shock-absorbing pad for a high-voltage distribution box provided in this application embodiment includes a connecting portion 10, a first shock-absorbing portion 20, and a second shock-absorbing portion 30. The connecting portion 10 has a first through hole 11 and a snap-fit ​​groove 12. The snap-fit ​​groove 12 has a first abutment surface 121 and a second abutment surface 122 spaced apart. The first shock-absorbing portion 20 is connected to the connecting portion 10 and has a second through hole 21, a first groove 22, and a first arc groove 23. The second through hole 21 is linearly connected to the first through hole 11. The first groove 22 is located on the side of the first shock-absorbing pad away from the connecting portion 10 and is connected to the second through hole 21. The first circular arc groove 23 is circumferentially spaced around the first groove 22, and the axis of the first circular arc groove 23 passes through the center of the circumference around which it is surrounded; the second damping part 30 is connected to the connecting part 10 and has a third through hole 31, a second groove 32 and a second circular arc groove 33. The third through hole 31 is linearly connected to the first through hole 11 and the second through hole 21. The second groove 32 is located on the side of the second damping part 30 away from the connecting part 10 and is connected to the third through hole 31. The second circular arc groove 33 is circumferentially spaced around the second groove 32, and the axis of the second circular arc groove 33 passes through the center of the circumference around which it is surrounded. The connecting portion 10 of this application is provided with a first through hole 11 and a snap-fit ​​groove 12. The first through hole 11 is used for the sleeve 50 and bolt to pass through. The first damping portion 20 and the second damping portion 30 are respectively provided with a first groove 22 and a second groove 32 at the ends away from the connecting portion 10, so as to provide more elastic clearance space for the connecting portion 10 in the extension direction of the first through hole 11 and improve the elastic damping performance of the damping pad. At the same time, the first damping portion 20 and the second damping portion 30 are respectively provided with a first arc groove 23 and a second arc groove 33 at the ends away from the connecting portion 10. The arc-shaped groove structure can undergo bending and tensile composite deformation under load, and the material generates more complex elastic deformation along the arc direction, extending the deformation path. The length of the impact energy distribution and transmission along the arc direction is increased, which can absorb more elastic potential energy and improve the damping effect.
