Description

Technical Field

[0001] The utility model relates to a vibration table connecting seat, in particular to a vibration table connecting seat for vibration testing of products such as in-vehicle chargers. Background Art

[0002] During the production process of in-vehicle chargers, there is a need for finished product vibration testing. Generally, the finished product is fixed on a bracket through fasteners, and the bracket is fixed on a vibration test table through fasteners. For example, a bracket for vibration testing of an in-vehicle charger disclosed in the patent with the publication number CN202372330U includes a part connected to the vibration test table and a part for supporting the charger. The part connected to the vibration test table is a flat plate with connection holes for connecting to the vibration test table on it. The part for supporting the charger is vertical plates perpendicularly connected to both sides of the flat plate, and two horizontal shelves are inwardly folded at the upper ends of the two vertical plates; vertical upper and lower triangular reinforcing ribs are connected at the inner corners of the flat plate and the two vertical plates perpendicular to both sides and at the inner corners of the two vertical plates and the upper horizontal shelves; there are charger fixing holes on the two horizontal shelves.

[0003] The above-mentioned bracket is obtained by bending a sheet of sheet metal. The overall structural strength is poor. Although reinforcing ribs are provided between the vertical plates, the flat plate and the supporting part, deformation still occurs after long-term use, which will cause the supporting part to deviate from the set position, making it difficult to position and fix the in-vehicle charger on the bracket, and the use is unreliable. Content of the Utility Model

[0004] The purpose of the utility model is to provide a vibration table connecting seat with higher structural strength, which can ensure the positioning effect of the in-vehicle charger and is convenient for vibration testing.

[0005] To achieve the above purpose, the utility model adopts a vibration table connecting seat, which includes a connecting seat body. Both opposite sides of the connecting seat body have upwardly extending supporting parts. A bottom is connected between the lower ends of the two supporting parts. There is a first fixing hole for connecting to the vibration table at the bottom. The thickness of the supporting part is greater than or equal to the width of the upper end surface of the supporting part. A plurality of first connecting parts are connected between the two supporting parts at intervals. A second connecting part is connected between adjacent two first connecting parts. The supporting part, the bottom, the first connecting part and the second connecting part are integrally formed. The thicknesses of the first connecting part and the second connecting part are both smaller than the thickness of the supporting part. The first connecting part and the second connecting part are both connected to the bottom. The first fixing hole is located at the connection of the first connecting part and the second connecting part. The supporting part is also provided with a third fixing hole for connecting to the vibration table.

[0006] The utility model forms a connection seat body through an integrally formed support part, a bottom part, a first connection part and a second connection part, realizing the optimization of the structure, having better overall stability and rigidity, and being able to ensure the overall structural strength; it can be made of materials such as Al6061, etc., to further ensure high structural strength under the condition of being relatively light as a whole, avoid deformation of the connection seat body under the influence of long-term vibration, avoid deviation of the first and second fixing holes of the connection seat body for connecting the vibration table or the test piece from the set positions, thereby extending the service life, ensuring the effective connection of test pieces such as in-vehicle chargers, making the positioning and fixing effect of test pieces such as in-vehicle chargers better, and ensuring the vibration test effect.

[0007] Among them, the thicknesses of the first connection part and the second connection part are less than that of the support part, which helps to reduce the overall weight and does not affect the structural strength at the same time; not only does the bottom have a first fixing hole, but the support part also has a third fixing hole, which can improve the stability of connection with the vibration table and can better transmit the vibration force to ensure the vibration test effect of test pieces such as in-vehicle chargers.

[0008] Preferably, the upper end surfaces of the first connection part and the second connection part are both lower than the upper end surface of the support part.

[0009] By forming an avoidance groove between the upper end surfaces of the first connection part and the second connection part and the side wall of the support part, only the two ends of the test piece such as an in-vehicle charger are connected to the connection seat body, making the middle part of the test piece overhead and ensuring the safety of the test piece during vibration testing. The upper end surfaces of the first connection part and the second connection part are relatively low, which can make the center of gravity of the entire connection seat lower, so that the overall structural stability of the connection seat is better.

[0010] Preferably, the lower end surface of the connection seat body corresponding to the support part has several upwardly extending extension grooves, and adjacent two extension grooves are separated by a third connection part, and the extension direction of the third connection part is the same as the extension direction of the first connection part or the second connection part.

[0011] By providing the extension grooves, the weight of the connection seat of the utility model is further reduced, which is convenient for vibration testing. And it can make the force transmitted by the vibration table more dispersed, reduce stress concentration, and extend the service life of the connection seat of the utility model.

[0012] Preferably, both opposite sides of the connection seat body have one of the first connection parts, and both opposite sides of the connection seat body have the first fixing holes, and the first fixing holes located on both sides of the connection seat body penetrate the side wall of the first connection part.

[0013] The above solution enables both sides of the connecting seat of the present utility model to be connected to the vibration table through fasteners, providing a more balanced force distribution and enhancing the connection stability between the connecting seat and the vibration table. Moreover, the side wall of the first connecting portion serves as a part of the first fixing hole, which helps to increase the structural strength of the connecting seat body, especially when bearing a large vibration force.

[0014] The present utility model has the advantages of higher structural strength, ensuring the positioning effect of the in-vehicle charger, and facilitating vibration testing. BRIEF DESCRIPTION OF THE DRAWINGS

A bottom portion 2 is connected between the lower ends of the two support portions 1. The thickness of the support portion 1 (the distance between the front and rear surfaces of the support portion) is greater than or equal to the width of the upper end surface of the support portion 1. A plurality of first connecting portions 3 are connected between the two support portions 1 at intervals in the left-right direction. A second connecting portion 4 extending in the left-right direction is connected between two adjacent first connecting portions 3.

The third fixing holes 12 on each supporting portion 1 in this embodiment are arranged side by side at equal intervals, and all the first fixing holes 21 at the bottom 2 in this embodiment are arranged side by side at equal intervals.

[0021] As Figure 2 shown, there are a number of upwardly extending extension grooves 10 corresponding to the supporting portion 1 on the lower end surface of the connecting seat body 100, and adjacent two extension grooves 10 are separated by a third connecting portion 5, and the extending direction of the third connecting portion 5 is the same as the extending direction of the first connecting portion 3.
