Description

Technical Field

[0001] This utility model belongs to the technical field of ARINC chassis vibration testing tools for electronic equipment manufacturing, and specifically relates to a mounting base for chassis vibration testing. Background Technology

[0002] ARINC chassis are a type of airborne electronic equipment. Typically, a chassis contains multiple PCBs and connectors, with complex connections between the components. To ensure high reliability, vibration testing of the chassis is necessary.

[0003] During vibration testing, the ARINC chassis needs to be fixed to the vibration test bench. However, the current method of fixing the ARINC chassis involves first installing the front locking device and the rear ARINC connector onto a standard mounting bracket. This standard mounting bracket is made of sheet metal and has relatively poor rigidity. After placing it on the test bench, clamping blocks are used to press the chassis firmly onto the vibration test bench. Because this installation method applies pressure to the chassis, it cannot accurately reflect the chassis's performance in a vibration environment during actual vibration testing.

[0004] Therefore, this patent application is filed. Summary of the Invention

[0005] The purpose of this invention is to provide a mounting base for chassis vibration testing, thereby solving the aforementioned technical problem of failing to accurately reflect the performance of the chassis in a vibration environment.

[0006] This utility model is achieved through the following technical solution:

[0007] A mounting base for chassis vibration testing includes a base and a mounting plate. The mounting plate is fixed to the base. The base has multiple fixing holes for connecting to a vibration test bench. The mounting plate has multiple connector mounting holes for connecting to connectors on the chassis. The base has locking device mounting holes for connecting locking devices on the chassis.

[0008] As a preferred design, the base is a quadrilateral base with equal length and width. Multiple fixing holes are arranged linearly along the diagonal of the quadrilateral base, and the spacing between fixing holes near the center of the base is smaller than the spacing between fixing holes away from the center of the base.

[0009] As a preferred design, the base has a length of 40-50cm and a thickness of 8-8.5cm.

[0010] As a preferred design, the mounting plate has a limiting window in the middle, and the connector mounting holes are provided around the limiting window.

[0011] As a preferred design, the mounting plate is connected to a reinforcing member, which includes a first reinforcing plate, a second reinforcing plate and a third reinforcing plate. Two of each of the first, second and third reinforcing plates are provided. The first and third reinforcing plates are located on the front and rear sides of the mounting plate, respectively, and the second reinforcing plate is located on both sides of the mounting plate. Each of the reinforcing plates is a triangular plate.

[0012] As a preferred design, the limiting window is also provided with a limiting groove corresponding to the connector on the chassis.

[0013] As a preferred design, a heat dissipation groove is provided in the middle of the base, and a fan adapter hole is provided around the heat dissipation groove.

[0014] As a preferred design, the bottom of the base is provided with a cable fixing hole and a cable groove for fixing the fan cable.

[0015] As a preferred design, the bottom of the base has multiple weight-reducing slots.

[0016] As a preferred design, the mounting base is an integrally machined structure, or the base (1) and the mounting plate (2) are welded together, or the base (1) and the mounting plate (2) are locked together by screws.

[0017] The advantages and beneficial effects of this utility model compared to the prior art are:

[0018] This utility model provides a mounting base for chassis vibration testing. By providing fixing holes on the base and using screws to fix the base to the vibration test bench, the installation method is simple and secure, eliminating the need to apply pressure to the chassis and providing a more realistic feedback of vibration conditions. Furthermore, by providing connector mounting holes and locking device mounting holes to stably mount the chassis on the mounting base, the installation and fixing method between the chassis and the mounting base is consistent with the actual installation method of the chassis. This largely avoids the impact of the installation and fixing method on the chassis vibration test, and can truly reflect the chassis's performance in a vibration environment during actual vibration testing, resulting in more accurate test results.

The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0028] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be apparent to those skilled in the art that these specific details are not necessary to implement the present invention.

[0031] like Figures 1-3 As shown, a mounting base for chassis vibration testing includes a base 1 and a mounting plate 2. The mounting plate 2 is fixed to the base 1. The base and mounting plate can be welded together or locked with screws. The base 1 has multiple fixing holes 3 for connecting to a vibration test bench. The fixing holes 3 are countersunk holes, through which the base 1 is fixed to the vibration test bench. The mounting plate 2 has multiple connector mounting holes 4, through which connectors 15 at the rear of the chassis are fixed to the mounting plate 2. The base 1 has locking device mounting holes 5, which are also countersunk holes. Figure 1 Two locking device mounting holes 5 are provided in the middle, and the locking device 14 at the front of the chassis is fixed to the base 1 through the locking device mounting holes 5.

[0032] In this embodiment, by setting fixing holes 3 on the base 1, the base 1 is fixedly installed to the vibration test bench using screws. This installation method is simple and secure, eliminating the need to apply pressure to the chassis. Instead, by setting connector mounting holes 4 and locking device mounting holes 5, the chassis is stably installed on the mounting base. Thus, the installation and fixing method between the chassis and the mounting base is consistent with the actual installation method of the chassis, which can largely avoid the impact of the installation and fixing method on the chassis vibration test. In the actual vibration test process, it can truly reflect the performance of the chassis in the vibration environment, and the test results are more accurate.

[0033] Furthermore, the base 1 is designed as a quadrilateral base 1, with equal length and width. The four corners of the base 1 are rounded. Two sets of linearly arranged fixing holes 3 are provided along the diagonals of the quadrilateral base 1, with the spacing between the fixing holes 3 closer to the center of the base 1 being smaller than the spacing between the fixing holes 3 further away from the center of the base 1. This allows for the installation of more fixing holes 3 at the center of the base 1, further enhancing the stability of the mounting base on the test bench.

[0034] Even better, the length of base 1 is set to 40~50cm, the thickness of base 1 is set to 8~8.5cm, and the entire base 1 is a square platform with a certain thickness, which can not only provide good support for the chassis installed on it, but also make the mounting base stable on the test platform.

[0035] In this embodiment, the mounting plate 2 has a limiting window 6 in the middle for placing the chassis connector 15, and multiple connector mounting holes 4 are provided around the limiting window 6 and along the edge of the limiting window 6 to stably install the chassis connector 15 so that the tail end of the connector 15 is firmly fixed.

[0036] Reinforcing members are also connected to the mounting plate 2. These include a first reinforcing plate 701, a second reinforcing plate 702, and a third reinforcing plate 703. Two of each of these plates are symmetrically arranged. The first and third reinforcing plates 701 and 703 are located on the front and rear sides of the mounting plate 2, respectively, while the second reinforcing plate 702 is located on both sides of the mounting plate 2. Each reinforcing plate is a triangular plate. By using multiple reinforcing plates, a limiting protection is formed at the machine connection end of the chassis, making the connection between the chassis and the mounting base more stable. Furthermore, a limiting groove 8 corresponding to the connector 15 on the chassis is provided on the limiting window 6. The limiting groove 8 and the first reinforcing plates 701 on both sides can limit the connection of the connector 15 end of the chassis. Example 2:

[0037] Based on Embodiment 1, a heat dissipation groove 9 is further provided in the middle of the base 1, and a fan adapter hole 10 is provided around the periphery of the heat dissipation groove 9. A fan can be installed at the bottom of the base 1, located at the position of the heat dissipation groove 9, and the fan is installed on the base 1 through the fan adapter hole 10. The bottom of the base 1 also has a cable fixing hole 3 and a cable groove 12 for fixing the fan cable. The fan is used to dissipate heat from the chassis.

[0038] Better still, in this embodiment, a plurality of weight-reducing slots 13 are provided at the bottom of the base 1. Since the base 1 has a certain thickness, the weight-reducing slots 13 at the bottom of the base 1 can play a role in weight reduction.

[0039] In this embodiment, the mounting base can be further designed as an integrally machined structure, which can improve the overall rigidity of the mounting base.

[0040] like Figure 4 , 5 The diagram shows the state of mounting the chassis onto the mounting base of this utility model.

[0041] The above specific embodiments further illustrate the purpose, technical solution and beneficial effects of this utility model. It should be understood that the above are only specific embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
