Description

Technical Field

[0001] The utility model relates to the technical field of vehicle manufacturing, in particular to a rear support structure for an engine stand and the engine stand. Background Art

[0002] The engine test bench is also called the engine performance test bench, which is mainly used for engine performance testing and technology development. The engine test bench is generally composed of a test bench trolley, a front support structure, a rear support structure, a gantry, a shock absorber block, a test system, etc. The front support structure is used to connect to the front side of the engine, and the rear support structure is used to connect to the gantry and the shock absorber block. The gantry is connected to the rear side of the engine. After long-term bench testing, since the shock absorber block is prone to aging, it is necessary to replace the shock absorber block regularly to meet the bench test standards. However, the rear support structure of the engine test bench is currently an integrated structure with the gantry and the shock absorber block. When replacing the shock absorber block, the entire tooling needs to be replaced, that is, the rear support structure and the gantry need to be disassembled at the same time, resulting in frequent replacement of the rear support structure and the gantry, cumbersome operation, and increased costs. Utility Model Content

[0003] The utility model provides a rear support structure for an engine stand and the engine stand, so as to solve at least a part of the technical problems of the existing rear support structure of the engine stand, the gantry and the shock absorbing block, which are complicated to disassemble and increase the cost.

[0004] According to one aspect of the utility model, a rear support structure for an engine pedestal is provided, wherein the engine pedestal includes a shock absorbing block and a gantry, and the rear support structure includes: a first connecting portion, which is detachably connected to the shock absorbing block; and a second connecting portion, which is vertically connected to the first connecting portion and detachably connected to the gantry.

[0005] The rear support structure provided by the utility model includes a first connection part and a second connection part. When the rear support structure is used for an engine test bench, the first connection part is first connected to the shock-absorbing block of the engine test bench, and then the gantry is connected to the second connection part, and the engine is connected to the gantry, so that the engine is fixed to the engine test bench, so as to facilitate the performance test of the engine. In addition, the second connection part is arranged perpendicular to the first connection part, so that the rear support structure is adapted to the structure of the gantry and the rear side of the engine to be tested, which is conducive to the connection and fixation of the rear support structure with the gantry and the engine.

[0006] By the above method, the first connection part of the rear support structure is detachably connected to the shock-absorbing block, and the second connection part of the rear support structure is detachably connected to the gantry. When the rear support structure, the gantry or the shock-absorbing block is damaged, only the rear support structure, the gantry or the shock-absorbing block need to be replaced accordingly, without replacing the rear support structure, the gantry and the shock-absorbing block at the same time. Compared with the existing rear support structure, the utility model facilitates the installation and disassembly of the rear support structure, the gantry and the shock-absorbing block separately, and the replacement operation is simpler and the replacement cost is lower.

[0007] In a further preferred embodiment, the second connection portion is connected to one end of the first connection portion and extends along a thickness direction of the first connection portion.

[0008] In this solution, the second connection part is extended along the thickness direction of the first connection part, which can improve the structural strength of the connection between the first connection part and the second connection part, thereby improving the connection strength between the rear support structure and the gantry.

[0009] In a further preferred solution, the rear support structure further includes a reinforcement portion, and the reinforcement portion is connected to the first connection portion and the second connection portion.

[0010] In this solution, the rear support structure also includes a reinforcement portion, which is connected to the first connection portion and the second connection portion at the same time. The reinforcement portion can improve the connection strength between the first connection portion and the second connection portion, thereby improving the structural strength of the rear support structure. When the engine is tested, the rear support structure can be stably connected to the gantry, thereby stably supporting the engine and ensuring the accuracy of the engine test results.

[0011] In a further preferred embodiment, the reinforcing portion includes a first reinforcing plate and a second reinforcing plate, the first reinforcing plate is connected to the first connecting portion and the second connecting portion, and the second reinforcing plate is connected to the first connecting portion and the second connecting portion; the first reinforcing plate and the second reinforcing plate are arranged in a mirror-symmetrical manner.

[0012] In this solution, the first reinforcing plate is used to connect with the first connection part and the second connection part at the same time, and the second reinforcing plate is used to connect the first connection part and the second connection part at the same time. The first reinforcing plate and the second reinforcing plate are used to reinforce the first connection part and the second connection part at the same time, so that the connection strength between the first connection part and the second connection part can be improved. In addition, since the first reinforcing plate and the second reinforcing plate are arranged in mirror symmetry, when the engine is fixed to the first connection part and the second connection part via the gantry, the first reinforcing plate and the second reinforcing plate can evenly disperse the force from the first connection part and the second connection part, so that the force of the first connection part and the second connection part is more balanced, avoiding the situation where the first connection part and the second connection part are damaged due to the uneven local force.

[0013] In a further preferred solution, the first reinforcing plate and the second reinforcing plate are respectively arranged on both sides of a connection between the first connecting portion and the second connecting portion.

[0014] In this solution, the first reinforcing plate and the second reinforcing plate are respectively arranged on both sides of the connection between the first connecting part and the second connecting part. The first reinforcing plate can be used to reinforce one side of the connection between the first connecting part and the second connecting part, and the second reinforcing plate can be used to reinforce the other side of the connection between the first connecting part and the second connecting part. In this way, the connection between the first connecting part and the second connecting part can be effectively prevented from being broken, and the connection strength between the first connecting part and the second connecting part is guaranteed.

[0015] In a further preferred solution, the bottom surface of the reinforcement portion is flush with the bottom surface of the first connecting portion.

[0016] In this solution, when the rear support structure is fixed on the shock-absorbing block, the bottom surface of the first connection part abuts against the surface of the shock-absorbing block. Since the bottom surface of the reinforcing part and the bottom surface of the first connection part are located in the same plane, the bottom surface of the reinforcing part also abuts against the surface of the shock-absorbing block. Therefore, through the direct contact between the reinforcing part and the shock-absorbing block, the force on the first connection part can be dispersed to avoid damage caused by excessive force on the first connection part. At the same time, the force can be effectively transmitted to the shock-absorbing block to improve the shock-absorbing effect.

[0017] In a further preferred solution, the first connecting portion is provided with a first mounting hole for connecting with the shock absorbing block.

[0018] In this solution, the first mounting hole passes through the top and bottom surfaces of the first connecting part. When the first connecting part is aligned with the mounting position of the shock absorbing block, a connecting member such as a bolt can pass through the first mounting hole and be connected to the corresponding mounting position on the shock absorbing block, thereby fixing the first connecting part to the shock absorbing block, thereby realizing the connection and fixation between the rear supporting structure and the shock absorbing block.

[0019] In a further preferred solution, the second connecting portion is provided with a second mounting hole for connecting with the gantry.

[0020] In this solution, the second mounting hole passes through the top and bottom surfaces of the second connecting part. When the second connecting part is aligned with the mounting position of the gantry, a connecting part such as a bolt can pass through the second mounting hole and be connected to the corresponding mounting position on the gantry, thereby fixing the gantry on the second connecting part and the engine on the gantry, thereby realizing the connection and fixation between the rear support structure and the engine.

[0021] In a further preferred solution, the first connecting portion is connected to the midline of the second connecting portion; the second connecting portion is provided with a plurality of the second mounting holes, and the plurality of the second mounting holes are evenly distributed on both sides of the midline of the second connecting portion.

[0022] In this solution, after the second connecting part is connected and fixed to the gantry via multiple second mounting holes, since the multiple second mounting holes are evenly distributed on both sides of the center line of the second connecting part, the force between the second connecting part and the gantry can be more balanced, thereby avoiding damage to the second connecting part or the gantry due to local uneven force.

[0023] According to another aspect of the utility model, an engine stand is provided, comprising the above-mentioned rear support structure.

[0024] The rear support structure, the shock absorbing block and the gantry are a separate structure. When the rear support structure, the shock absorbing block or the gantry is damaged, only the rear support structure, the shock absorbing block or the gantry needs to be replaced accordingly, without replacing the rear support structure, the shock absorbing block and the gantry at the same time, thereby reducing the replacement cost and the production cost of the engine test bench.

[0025] In summary, the rear support structure for the engine test bench and the engine test bench provided by the utility model have at least the following advantages: the rear support structure includes a first connection part and a second connection part, and the second connection part is arranged perpendicular to the first connection part, so that the rear support structure is adapted to the structure of the gantry and the rear side of the engine to be tested, which is conducive to the connection and fixation of the rear support structure with the gantry and the engine. In addition, the first connection part is detachably connected to the shock-absorbing block, and the second connection part is detachably connected to the gantry, that is, the rear support structure, the shock-absorbing block and the gantry are split structures. When the rear support structure, the shock-absorbing block or the gantry is damaged, it is only necessary to replace the rear support structure, the shock-absorbing block or the gantry accordingly, without replacing the rear support structure, the shock-absorbing block and the gantry at the same time, so the replacement operation is simpler and the replacement cost is lower.

[0039] Please refer to Figures 1 to 5 According to an embodiment of the utility model, the rear support structure for the engine pedestal provided by the utility model comprises at least a first connection part 100 and a second connection part 200 .

[0040] The first connecting part 100 is a rectangular plate-shaped structure, and the first connecting part 100 can be detachably connected to the shock-absorbing block of the engine bench to reduce the vibration of the engine during the bench test. The engine bench and the shock-absorbing block thereon are both existing structures, which will not be described in detail in this article.

[0041] The second connecting part 200 is a rectangular plate-shaped structure, and the second connecting part 200 can be detachably connected to the gantry, and the engine is installed on the gantry, wherein the gantry is an existing structure and will not be described in detail herein. In addition, the second connecting part 200 is arranged perpendicular to the first connecting part 100, so that the rear support structure is adapted to the structure of the rear side of the gantry and the engine to be tested, which is conducive to the connection and fixation of the rear support structure with the gantry and the engine.

[0042] The rear support structure of this embodiment is used to be installed on the rear side of the engine rig, and the second connection part 200 of the rear support structure is connected to the gantry, and is connected to the rear side of the engine through the gantry to fix the rear side of the engine. Specifically, when the rear support structure is used, the first connection part 100 is first connected to the shock-absorbing block of the engine rig, and then the gantry is connected to the second connection part 200, and the engine is connected to the gantry, so that the engine is fixed to the engine rig, so as to facilitate the performance test of the engine.

[0043] Through the above structural design, the first connection part 100 of the rear support structure is detachably connected to the shock-absorbing block, and the second connection part 200 of the rear support structure is detachably connected to the gantry, that is, the rear support structure, the shock-absorbing block and the gantry are split structures. When the rear support structure, the shock-absorbing block or the gantry is damaged, it is only necessary to replace the rear support structure, the shock-absorbing block or the gantry accordingly, without replacing the rear support structure, the shock-absorbing block and the gantry at the same time. For example, when the shock-absorbing block is aged or the shock-absorbing effect is poor, the shock-absorbing block can be replaced separately. Compared with the existing rear support structure, the rear support structure, the shock-absorbing block or the gantry can be installed and disassembled separately in the utility model, and the replacement operation is simpler and more convenient, and the manufacturing cost of the rear support structure is lower.

[0044] As a further preferred implementation scheme, based on the above scheme, the specific embodiments of the present invention may also include one or more of the following additions or combinations.

[0045] In a further preferred solution, the second connection part 200 is connected to one end of the first connection part 100 and extends along the thickness direction of the first connection part 100. In this embodiment, the second connection part 200 is extended along the thickness direction of the first connection part 100, so that the second connection part 200 protrudes from the surface of the first connection part 100 in the thickness direction of the first connection part 100, thereby improving the structural strength of the connection between the first connection part 100 and the second connection part 200, thereby improving the connection strength between the rear support structure and the gantry.

[0046] In a further preferred solution, the rear support structure further includes a reinforcement portion, which is connected to the first connection portion 100 and the second connection portion 200. Connecting the reinforcement portion to both the first connection portion 100 and the second connection portion 200 can make the rear support structure stronger, which can meet the test use of engines with larger displacements, and make the engine bench applicable to a wider range of engine models.

[0047] Specifically, the reinforcement part is a plate-like structure, one side of the reinforcement part is connected to the first connection part 100, and the other side of the reinforcement part is connected to the second connection part 200. The reinforcement part can improve the connection strength between the first connection part 100 and the second connection part 200, thereby improving the structural strength of the rear support structure, so that when the engine is tested, the rear support structure can stably support the engine and ensure the accuracy of the engine test results.

[0048] In a further preferred embodiment, the reinforcing portion includes a first reinforcing plate 310 and a second reinforcing plate 320, the first reinforcing plate 310 is connected to the first connecting portion 100 and the second connecting portion 200, and the second reinforcing plate 320 is connected to the first connecting portion 100 and the second connecting portion 200; the first reinforcing plate 310 and the second reinforcing plate 320 are arranged in a mirror-symmetrical manner.

[0049] Specifically, the first reinforcing plate 310 and the second reinforcing plate 320 are both plate-like structures. The first reinforcing plate 310 is used to connect the first connecting part 100 and the second connecting part 200 at the same time, and the second reinforcing plate 320 is used to connect the first connecting part 100 and the second connecting part 200 at the same time. The first reinforcing plate 310 and the second reinforcing plate 320 are used to reinforce the first connecting part 100 and the second connecting part 200 at the same time, so that the structural strength between the first connecting part 100 and the second connecting part 200 can be improved. Furthermore, since the first reinforcing plate 310 and the second reinforcing plate 320 are arranged in a mirror-symmetrical manner, when the engine and the gantry are fixed to the first connecting part 100 and the second connecting part 200, the first reinforcing plate 310 and the second reinforcing plate 320 can evenly disperse the force from the first connecting part 100 and the second connecting part 200, so that the force of the first connecting part 100 and the second connecting part 200 is more balanced, avoiding the situation where the local force of the first connecting part 100 and the second connecting part 200 is uneven, causing damage to the first connecting part 100 and the second connecting part 200.

[0050] In a further preferred solution, the first reinforcing plate 310 and the second reinforcing plate 320 are respectively arranged on both sides of the connection between the first connecting part 100 and the second connecting part 200. After the engine is fixed to the shock absorbing block by the first connecting part 100 and the second connecting part 200, the engine may vibrate during the bench test, resulting in an unstable connection between the first connecting part 100 and the second connecting part 200, or even a breakage at the connection between the first connecting part 100 and the second connecting part 200.

[0051] In this embodiment, the first reinforcing plate 310 is arranged on one side of the connection between the first connecting part 100 and the second connecting part 200, and the second reinforcing plate 320 is arranged on the other side of the connection between the first connecting part 100 and the second connecting part 200. The first reinforcing plate 310 and the second reinforcing plate 320 can be used to reinforce the opposite sides of the connection between the first connecting part 100 and the second connecting part 200. In this way, the connection strength between the first connecting part 100 and the second connecting part 200 can be further improved, and the fracture of the connection between the first connecting part 100 and the second connecting part 200 can be effectively avoided, thereby ensuring the test requirements of the engine bench.

[0052] In a further preferred embodiment, the bottom surface of the reinforcing portion is flush with the bottom surface of the first connecting portion 100. The bottom surfaces of the first reinforcing plate 310 and the second reinforcing plate 320 are flush with the bottom surface of the first connecting portion 100, that is, the bottom surfaces of the first reinforcing plate 310 and the second reinforcing plate 320 and the bottom surface of the first connecting portion 100 are located in the same plane. When the rear support structure is fixed on the shock absorbing block, the bottom surface of the first connecting portion 100 abuts against the surface of the shock absorbing block, and at this time, the bottom surfaces of the first reinforcing plate 310 and the second reinforcing plate 320 also abut against the surface of the shock absorbing block. Therefore, by directly contacting the first reinforcing plate 310 and the second reinforcing plate 320 with the shock absorbing block, the force on the first connecting portion 100 can be dispersed to avoid damage caused by excessive force on the first connecting portion 100, and at the same time, the force can be effectively transmitted to the shock absorbing block to improve the shock absorbing effect.

[0053] In a further preferred solution, the first connecting portion 100 is provided with a first mounting hole 110 for connecting with the shock absorbing block. When the first connecting portion 100 needs to be connected with the shock absorbing block, a connecting member such as a bolt can pass through the first mounting hole 110 and be connected and fixed with the shock absorbing block to achieve the installation and fixation of the first connecting portion 100.

[0054] For example, the inner wall of the first mounting hole 110 may be provided with a thread, and the first mounting hole 110 passes through the first connecting part 100. Accordingly, the shock absorbing block is provided with a threaded hole that matches the first mounting hole 110. When installing the first connecting part 100, first align the first mounting hole 110 of the first connecting part 100 with the corresponding threaded hole on the shock absorbing block, and then pass the bolt through the first mounting hole 110 and tighten it in cooperation with the threaded hole, so as to fix the first connecting part 100 on the shock absorbing block, and realize the connection and fixation between the rear support structure and the shock absorbing block. Since the first connecting part 100 is detachably connected to the shock absorbing block through the first mounting hole 110, the shock absorbing block is easy to replace. Therefore, when testing engines of different models, shock absorbing blocks of different hardness can be selected according to the shock absorption needs, which can meet various tests of the engine bench.

[0055] In a further preferred embodiment, the second connecting portion 200 is provided with a second mounting hole 210 for connecting to the gantry. When the second connecting portion 200 needs to be connected to the gantry, a connecting member such as a bolt can pass through the second mounting hole 210 and be connected and fixed to the gantry, so as to support and fix the gantry and the engine.

[0056] For example, the inner wall of the second mounting hole 210 may be provided with a thread, and the second mounting hole 210 passes through the second connecting portion 200. Accordingly, the gantry has a threaded hole that matches the second mounting hole 210. When installing the engine, first align the second mounting hole 210 of the second connecting portion 200 with the corresponding threaded hole on the gantry, then pass the bolt through the second mounting hole 210 and tighten it in cooperation with the threaded hole, thereby fixing the gantry on the second connecting portion 200, and then connect the engine to the gantry, so as to achieve connection and fixation between the rear support structure and the engine.

[0057] In a further preferred solution, the first connection part 100 is connected to the midline of the second connection part 200 ; the second connection part 200 is provided with a plurality of second mounting holes 210 , and the plurality of second mounting holes 210 are evenly distributed on both sides of the midline of the second connection part 200 .

[0058] For example, refer to Figure 2 As shown, in this embodiment, the second connection part 200 is provided with four second mounting holes 210, and the four second mounting holes 210 are evenly distributed on both sides of the center line of the second connection part 200. When the second connection part 200 is connected and fixed to the gantry via the four second mounting holes 210, since the four second mounting holes 210 are evenly distributed on both sides of the center line of the second connection part 200, the force between the second connection part 200 and the gantry can be more balanced, thereby avoiding the situation where the second connection part 200 or the gantry is damaged due to uneven local force.

[0059] It can be understood that the number and positions of the second mounting holes 210 are not limited to the above examples. For example, in other optional embodiments, the number of second mounting holes 210 can be one, two, three, five, etc., and the second mounting holes 210 can also be arranged only on one side of the center line of the second connecting part 200, as long as the second connecting part 200 can be firmly connected to the gantry.

[0060] According to another embodiment of the utility model, an engine pedestal is provided, comprising the above-mentioned rear support structure. The rear support structure, the damping block and the gantry are separate structures. When the rear support structure, the damping block or the gantry is damaged, only the rear support structure, the damping block or the gantry needs to be replaced accordingly, without replacing the rear support structure, the damping block and the gantry at the same time, which can reduce the replacement cost and the manufacturing cost of the engine pedestal.

[0061] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.
