Description

Technical Field

[0001] This utility model relates to the field of automobile production technology, and in particular to a multi-functional test bench for automobile sleeper berths. Background Technology

[0002] A sleeper berth is a berth in a commercial vehicle where passengers can sleep. During the manufacturing process, the sleeper berth needs to undergo vibration testing. This is typically done by fixing a test frame to a vibration test bench. Existing test benches are used for vibration testing of sleeper berths. The test bench is directly fixed to the vibration test bench during testing, thus replacing the actual vehicle body with vibration testing on the sleeper berth test bench. This makes the testing operation during the production of sleeper berths more convenient and allows for vibration durability, indentation durability, and other tests, improving the effectiveness of the sleeper berth test bench for vibration testing.

[0003] Existing test benches are used for testing automotive sleeper berths. The equipment is directly fixed on the vibration test bench for testing. In order to meet the design performance and standard regulations, automotive sleeper berths need to undergo multiple performance tests during the production preparation stage. Most of these tests need to be carried out at the design location of the parts (parts in the vehicle mounting state). However, in general, parts manufacturers find it difficult to conduct tests on the actual vehicle body, which makes the testing operation of automotive sleeper berths inconvenient during production and affects the testing operation of automotive sleeper berths. To address this issue, we propose a multi-functional test bench for automotive sleeper berths. Utility Model Content

[0043] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] See also Figure 1-6 As shown, this application provides a multi-functional test bench for automobile sleeper berths. The test bench is disposed on a test platform and includes:

[0045] The main body of the platform 1 includes a platform base plate 11, a support column 12 disposed on the platform base plate 11 along a first direction, and a platform top beam 13 disposed on the support column 12;

[0046] Fixing member 2, which is disposed on the support column 12, is used to fix one side of the berth along the first direction;

[0047] Bracket assembly 3, which is disposed on the base plate 11 of the platform along the second direction, is used to fix the two sides of the berth along the second direction;

[0048] Suspension assembly 4, which is disposed on the top beam, is used to fix the other side of the berth along the first direction.

[0049] The multi-functional test bench for car sleeper berths provided in this embodiment includes a main body 1, fasteners 2, bracket assemblies 3, and suspension assemblies 4. The main body 1 includes a base plate 11, support columns 12, and a top beam 13. The support columns 12 are firmly installed on both sides of the base plate 11 along a first direction, providing support for the top beam 13 and providing installation positions for the fasteners 2. The top beam 13 is mounted on the support columns 12, forming a stable frame structure together with the base plate 11 and support columns 12, providing a reliable installation foundation for the suspension assemblies 4.

[0050] The fixing component 2 is installed on the support column 12, and its main function is to fix one side of the berth along the first direction. The fixing component 2 can fix one side of the car berth with bolts or other connecting parts. The bracket assembly 3 is installed on both sides of the platform base plate 11 along the second direction to support and fix both sides of the berth along the second direction. During the test, the bracket assembly 3 can effectively distribute the load borne by the berth, prevent the berth from tilting or overturning, and ensure the safety and reliability of the test. The suspension assembly 4 is installed on the top beam 13 of the platform to fix the other side of the berth along the first direction.

[0051] By integrating the fastener 2, bracket assembly 3, and suspension assembly 4 onto the main body 1, the multi-functional automotive sleeper test bench can meet the testing needs of different types of automotive sleeper berths. In actual testing, the main body 1 is first placed on the test platform 6. Then, according to the sleeper berth model and size, the positions and angles of the fastener 2, bracket assembly 3, and suspension assembly 4 are adjusted to firmly fix the sleeper berth onto the main body 1. Next, according to the requirements of the test items, various performance tests are conducted on the sleeper berth using the test platform 6 or the test indentation head 7, such as vibration durability testing and indentation durability testing. In the vibration durability test, the structural integrity and reliability of the sleeper berth under long-term vibration are detected by simulating the vibration environment during vehicle operation. In the indentation durability test, the comfort and durability of the sleeper berth are detected by applying repeated pressure.

[0052] The suspension assembly 4 includes:

[0053] Fixed base 41, the fixed base 41 is disposed on the top beam 13 of the platform;

[0054] Connecting plate 42, the connecting plate 42 is disposed on the fixing base 41;

[0055] Hanging plate 43, which is detachably mounted on the connecting plate 42;

[0056] The sling 44 has its first end attached to the hanging plate 43 and its second end connected to the berth.

[0057] The multi-functional test bench for car sleeper provided in this embodiment includes a suspension component 4 consisting of a fixed base 41, a connecting plate 42, a hanging plate 43, and a sling 44. This component provides a stable and flexible fixation for the other side of the sleeper. It works in conjunction with the main body 1, the fixing component 2, and the bracket component 3, greatly enhancing the functionality and adaptability of the test bench.

[0058] The fixed base 41 is mounted on the top beam 13 of the test platform and can withstand various forces transmitted from the berth and slings 44 during testing. It not only provides a reliable installation foundation for the connecting plate 42 and the hanging plate 43, but also plays a role in force transmission and dispersion in the entire suspension assembly 4, evenly transferring the weight of the berth and the dynamic load during testing to the top beam 13 of the test platform, thereby ensuring the structural stability of the main body 1 of the test platform. The connecting plate 42 is mounted on the fixed base 41, and its function is to further enhance the connection stability between the fixed base 41 and the hanging plate 43, and to provide positioning for the installation of the hanging plate 43. The hanging plate 43 is detachably mounted on the fixed base 41 through the connecting structure. This detachable feature allows for easy replacement of hanging plates 43 of different sizes or structures when dealing with different models and specifications of berths, and also allows for adjustment of the position of the hanging plate 43 to meet diverse testing needs. The first end of the sling 44 is attached to the hanging plate 43, and the second end is connected to the berth. The sling 44 is typically made of high-strength, wear-resistant, and flexible materials, such as polyester fiber and nylon. These materials ensure load-bearing capacity while reducing wear on the berth surface. The connection between the sling 44 and the hanging plate 43 is secure and reliable, and it will not detach during testing. Furthermore, the length of the sling 44 is generally adjustable. Adjustment devices, such as buckles and pulley systems, allow the length of the sling 44 to be adjusted according to the actual height of the berth and testing requirements, ensuring the berth maintains a suitable height and angle while suspended.

[0059] The fixing base 41 includes:

[0060] Fixed plate 411, the connecting plate 42 is connected to the fixed plate 411;

[0061] The first sliding sleeve 412 is sleeved on the top beam 13 of the platform and is disposed on the fixing plate 411 and located on both sides of the connecting plate 42.

[0062] The first fastener 413 is disposed on the first sliding sleeve 412.

[0063] The multi-functional test bench for car sleeper berths provided in this embodiment has a first sliding sleeve 412 fitted onto the top beam 13 of the bench, providing flexibility for the installation and adjustment of the fixed seat 41 on the top beam 13, allowing the fixed seat 41 to be easily positioned on the top beam 13. The first sliding sleeve 412 is located on the fixed plate 411 and on both sides of the connecting plate 42. This layout not only enhances the connection stability between the fixed seat 41 and the top beam 13, but also effectively balances various forces transmitted from the connecting plate 42, the hanging plate 43, and the slings 44. In practical use, when it is necessary to adjust the position of the suspension assembly 4 according to the testing requirements of different sleeper berth models, the operator can quickly move the fixed seat 41 to the appropriate position by sliding the first sliding sleeve 412, improving the ease of operation of the test bench.

[0064] The first fastener 413 is mounted on the first sliding sleeve 412. Its function is to securely fix the first sliding sleeve 412 to the top beam 13 of the test bench after the fixed seat 41 is adjusted to the appropriate position. The first fastener 413 is generally a high-strength bolt or nut. By tightening the first fastener 413, sufficient friction can be generated between the first sliding sleeve 412 and the top beam 13 of the test bench, preventing the fixed seat 41 from shifting due to vibration or other external forces during the test. During vibration durability testing, the severe vibration during vehicle operation may generate a large impact force on the suspension assembly 4. At this time, the first fastener 413 can ensure that the fixed seat 41 always remains in the predetermined position, ensuring the accuracy and safety of the test. Moreover, the tightening force of the first fastener 413 can be adjusted according to the actual situation. For some test items with high requirements for fixed position accuracy, the tightening force can be appropriately increased to improve the stability of the fixed seat 41; while when the position of the fixed seat 41 needs to be frequently adjusted, the tightening force can be appropriately reduced to facilitate operation by the operator.

[0065] In the research and development and production of automotive sleeper berths, extensive performance testing is required for different models and specifications of sleeper berths, necessitating a test bench capable of quickly adapting to various testing needs. The adjustability and stability of the fixed base 41 allow operators to flexibly adjust the position of the suspension assembly 4 according to the specific dimensions of the sleeper berth and testing requirements, ensuring that the fixed base 41 remains stable throughout the testing process. This not only improves testing efficiency but also reduces the risk of testing errors and equipment damage caused by instability in the fixed base 41.

[0066] The sling 44 includes:

[0067] The belt body 441 has its first end connected to the hanging plate 43;

[0068] Buckle plate 442, the second end of the main body 441 is connected to buckle plate 442, and buckle plate 442 is set on the other side of the berth along the first direction.

[0069] The multi-functional test bench for car sleeper berths provided in this embodiment typically uses a high-strength, wear-resistant, and flexible material, such as multi-layer composite polyester fiber, for the main body 441. The connection between the first end of the main body 441 and the hanging plate 43 is achieved, for example, through a specially designed metal ring or high-strength stitching process, ensuring a tight connection between the main body 441 and the hanging plate 43, preventing detachment under any testing conditions. A buckle plate 442 is connected to the second end of the main body 441, providing a stable connection to the other side of the sleeper berth. The buckle plate 442 fits snugly against the edge of the sleeper berth, providing a stable fixing point. In actual operation, the buckle plate 442 is connected to the sleeper berth through a special clamping or snap-fit ​​structure. This connection method provides sufficient clamping force to prevent displacement of the sleeper berth during testing, and allows for convenient and quick disassembly and installation when the sleeper berth needs to be replaced or the testing device adjusted.

[0070] The connecting plate 42 has multiple fixing holes vertically, and the multiple fixing holes form a fixing hole group. The connecting plate 42 has multiple fixing hole groups spaced apart.

[0071] The multi-functional test bench for car sleeper berths provided in this embodiment has multiple vertically formed fixing holes on the connecting plate 42, which are distributed at intervals on the connecting plate 42, providing a variety of options for the installation of the hanging plate 43 and other related components. Different car sleeper berths differ in size, structure, and the force points required during testing. Through these fixing hole groups, the installation position of the hanging plate 43 can be flexibly adjusted according to the specific sleeper model and testing requirements.

[0072] The bracket assembly 3 includes:

[0073] Bracket base 31, the bracket base 31 is slidably disposed on the base plate 11 of the platform;

[0074] The tray 32 is detachably mounted on the bracket base 31.

[0075] The multi-functional test bench for automotive sleeper berths provided in this embodiment features a detachable tray 32 mounted on a bracket seat 31, greatly enhancing the versatility of the bracket assembly 3 for different types of automotive sleeper berths. The tray 32 and bracket seat 31 are connected via a convenient detachable method, such as snap-fit ​​or bolt connection. In practical use, when testing sleeper berths with different structures or materials, a suitable tray 32 can be selected and replaced according to the characteristics of the sleeper berth. For example, for some sleeper berths with softer surfaces, an engineering plastic tray 32 with a smoother surface and better cushioning performance can be used; while for some heavier and more robust sleeper berths, a metal tray 32 with stronger load-bearing capacity can be used. This detachable design not only facilitates the maintenance and replacement of the tray 32, reducing equipment maintenance costs, but also allows the test bench to quickly adapt to diverse automotive sleeper berth testing needs, further improving testing efficiency. Furthermore, the bracket seat 31 is slidably mounted on the bench base plate 11, and its position can be adjusted as needed to achieve stable fixation of the sleeper berth.

[0076] In real-world automotive sleeper berth testing scenarios, performance tests need to be conducted on a large number of sleeper berths of different models and specifications. The adjustability and versatility of the bracket assembly 3 allow operators to quickly adjust the position of the bracket seat 31 and replace the appropriate tray 32 according to the characteristics of different sleeper berths, stably fixing the sleeper berth on the test bench. Whether conducting vibration durability tests, simulating the bumps and vibrations during vehicle operation, or applying repeated pressure to the sleeper berth in indentation durability tests, the bracket assembly 3 reliably provides stable support for the sleeper berth, ensuring the accuracy of the test results.

[0077] The bracket base 31 includes:

[0078] Bracket plate 311, wherein the bracket plate 32 is detachably mounted on the bracket plate 311;

[0079] The second slide 312 is sleeved on the base plate 11 of the frame;

[0080] The second fastener 313 is disposed on the second slide 312.

[0081] The multi-functional test bench for car sleeper berths provided in this embodiment uses a bracket plate 311 to fix the tray 32. The tray 32 and bracket plate 311 employ a convenient and reliable detachable connection method, commonly including snap-fit ​​connections and bolt connections. Snap-fit ​​connections are simple to operate, allowing for quick installation and removal of the tray 32, suitable for scenarios requiring frequent replacement of the tray 32 or changing its position to adapt to different sleeper berth types. Bolt connections, on the other hand, provide a more robust connection, ensuring that the tray 32 and bracket plate 311 remain tightly connected during more stringent tests, such as high-frequency vibration tests or large-load indentation tests, thus guaranteeing the safety and accuracy of the test.

[0082] The second slide block 312 is fitted onto the test bench base plate 11, providing a basis for the movement of the bracket seat 31 on the test bench base plate 11. When dealing with sleeper berths of different models, sliding the second slide block 312 allows the bracket seat 31 to be quickly positioned in the appropriate location, improving the operational efficiency of the test bench. The second fastener 313 is provided on the second slide block 312. After the bracket seat 31 slides to the appropriate position, the second fastener 313 is used to firmly fix the second slide block 312 to the test bench base plate 11, preventing the bracket seat 31 from shifting due to external forces during testing. The second fastener 313 is usually a high-strength bolt or nut. By tightening, sufficient friction is generated between the second slide block 312 and the test bench base plate 11, thereby achieving reliable fixation. During vibration durability testing, the intense vibrations generated during vehicle operation will exert a significant impact force on the bracket seat 31. At this time, the second fastener 313 ensures that the bracket seat 31 remains in the predetermined position, providing a stable support base for the pallet 32 ​​and the sleeper berth, thus guaranteeing the accuracy of the test results. Furthermore, the tightening force of the second fastener 313 can be adjusted according to actual testing requirements.
