Description

Technical Field

[0001] This utility model relates to the field of actuators, and in particular to an electro-hydraulic direct drive transmission device that is easy to assemble. Background Technology

[0002] The earliest application of electro-hydraulic direct-drive intelligent actuator technology was in the aircraft power fly-by-wire actuation system in the aviation field. The power fly-by-wire actuation system refers to the power transmission between the aircraft's secondary energy system and the various actuators of the actuation system, which is accomplished by transmitting electrical energy through electrical wires. This replaces the traditional airborne hydraulic actuation system, which transmits power through hydraulic pipelines throughout the fuselage. This has brought about a huge change to the aircraft's handling, control, and performance, while also improving the aircraft's survivability after damage.

[0003] The commonly used electro-hydraulic direct drive transmission equipment mainly consists of a hydraulic accumulator, an electrical energy storage device, and an electro-hydraulic actuator. The hydraulic accumulator is fixed by multiple connecting parts during installation, which is a relatively cumbersome assembly structure and also inconvenient for maintenance. Therefore, we propose an electro-hydraulic direct drive transmission device that is easy to assemble. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an electro-hydraulic direct drive transmission device that is easy to assemble. By adjusting the setting of the retaining ring, the hydraulic accumulator can be assembled after being placed on the retaining block, which solves the cumbersome steps of fixing multiple parts separately for the hydraulic accumulator. On this basis, the movable connection between the hydraulic accumulator and the adjusting retaining ring makes assembly convenient and disassembly relatively easy. Therefore, the maintenance and replacement of the hydraulic accumulator are also more convenient.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] An easy-to-assemble electro-hydraulic direct drive transmission device includes a main body mechanism, a fixing mechanism installed in the middle of the main body mechanism, an assembly mechanism installed above the fixing mechanism in the middle of the main body mechanism, and a hydraulic accumulator installed in the middle of the assembly mechanism.

[0007] The assembly mechanism includes an adjusting ring, a T-shaped rod is fixedly installed at the lower end of the adjusting ring, and a connecting block is fixedly installed at the lower end of the T-shaped rod. The connecting block has a threaded hole inside. The connecting block is installed at the lower end of the T-shaped rod, so that the structure of the T-shaped rod forms an I-shape. This makes it easy for the upper and lower ends of the T-shaped rod to have equal supporting force after it is fixed, thereby increasing the stability of the adjusting ring.

[0008] Furthermore, the main structure includes an energy storage device, a connector is fixedly installed in the middle of the energy storage device, and an electro-hydraulic actuator is fixedly installed at the outer end of the connector. By setting the connector, the electro-hydraulic actuator and the energy storage device can be connected together.

[0009] Furthermore, the fixing mechanism includes a sleeve, the outer end of which has a strip groove inside, and the outer end of which has an assembly groove outside the strip groove. A threaded rod is movably installed inside the assembly groove. A locking block is fixedly installed at the lower outer end of the sleeve. A limiting hole is provided at the inner end of the locking block. By providing the limiting hole, the lower end of the hydraulic accumulator can be limited when placed through the interior of the locking block, thereby increasing the stability of the lower part of the hydraulic accumulator after installation.

[0010] Furthermore, the adjusting retaining ring is movably installed on the outside of the sleeve via a T-shaped rod, and the threaded holes are symmetrically distributed inside the connecting block and located on the left and right sides of the T-shaped rod. By setting the adjusting retaining ring, the hydraulic accumulator can be assembled after being placed on the retaining block, which solves the cumbersome steps of fixing multiple components separately for the hydraulic accumulator.

[0011] Furthermore, the sleeve is fixedly installed in the middle of the outer end of the energy storage device, the strip groove is a T-shaped structure, the assembly groove is symmetrically distributed on both sides of the strip groove, and the upper end of the threaded rod can extend into the interior of the strip groove.

[0012] Furthermore, the limiting hole has a conical structure, and the outer end of the locking block and the adjusting ring have the same structure.

[0013] Furthermore, the hydraulic accumulator is movably mounted on the outside of the electric energy storage device, the hydraulic accumulator and the adjusting retaining ring are movably connected, and the lower end of the hydraulic accumulator is adapted to the limiting hole.

[0014] Furthermore, the threaded rod and the threaded hole are adapted to each other, and the T-shaped rod and the strip groove are adapted to each other.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. By adjusting the setting of the retaining ring, the hydraulic accumulator can be assembled immediately after being placed on the retaining block, which solves the cumbersome steps of fixing multiple parts separately. On this basis, the movable connection between the hydraulic accumulator and the adjusting retaining ring makes assembly convenient and disassembly relatively easy. Therefore, the maintenance and replacement of the hydraulic accumulator are also extremely convenient.

[0017] 2. The threaded rod connection structure allows it to extend into the inside of the strip groove, and the T-shaped rod is fixed inside the strip groove through the threaded hole. This structure facilitates the assembly of the hydraulic accumulator and also improves the stability after assembly. Attached Figure Description

It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0026] Reference Figure 1-5 As shown, a preferred embodiment of the present invention is an electro-hydraulic direct drive transmission device that is easy to assemble, including a main body 1, a fixing mechanism 2 installed in the middle of the main body 1, an assembly mechanism 3 installed above the fixing mechanism 2 in the middle of the main body 1, and a hydraulic accumulator 4 installed in the middle of the assembly mechanism 3.

[0027] The assembly mechanism 3 includes an adjusting ring 301. A T-shaped rod 302 is fixedly installed at the lower end of the adjusting ring 301. A connecting block 303 is fixedly installed at the lower end of the T-shaped rod 302. A threaded hole 304 is opened inside the connecting block 303. The connecting block 303 is installed at the lower end of the T-shaped rod 302, so that the structure of the T-shaped rod 302 forms an I-shape. This makes it easy for the upper and lower ends of the T-shaped rod 302 to have equal supporting force after it is fixed, thereby increasing the stability of the adjusting ring 301.

[0028] The main body 1 includes an energy storage device 101. A connector 102 is fixedly installed in the middle of the energy storage device 101. An electro-hydraulic actuator 103 is fixedly installed at the outer end of the connector 102. By setting the connector 102, the electro-hydraulic actuator 103 and the energy storage device 101 can be connected together.

[0029] The fixing mechanism 2 includes a sleeve 201. A strip groove 202 is formed inside the outer end of the sleeve 201. An assembly groove 203 is formed outside the strip groove 202 at the outer end of the sleeve 201. A threaded rod 204 is movably installed inside the assembly groove 203. A locking block 205 is fixedly installed at the lower outer end of the sleeve 201. A limiting hole 206 is formed at the inner end of the locking block 205. By setting the limiting hole 206, the lower end of the hydraulic accumulator 4 can be placed through the interior of the locking block 205, thereby increasing the stability of the lower part of the hydraulic accumulator 4 after installation.

[0030] The adjusting ring 301 is movably installed on the outside of the sleeve 201 via the T-shaped rod 302. The threaded holes 304 are symmetrically distributed inside the connecting block 303 and located on the left and right sides of the T-shaped rod 302. By setting the adjusting ring 301, the hydraulic accumulator 4 can be assembled after being placed on the locking block 205, which solves the cumbersome steps of fixing multiple parts separately for the hydraulic accumulator 4.

[0031] The sleeve 201 is fixedly installed in the middle of the outer end of the energy storage device 101. The strip groove 202 has a T-shaped structure. The assembly grooves 203 are symmetrically distributed on both sides of the strip groove 202. The upper end of the threaded rod 204 can extend into the interior of the strip groove 202. The connection structure of the threaded rod 204 allows it to extend into the interior of the strip groove 202. After that, the T-shaped rod 302 is fixed in the interior of the strip groove 202 through the threaded hole 304. This structure facilitates the assembly of the hydraulic accumulator 4 and also improves the stability after assembly.

[0032] The limiting hole 206 has a conical structure, and the outer end of the locking block 205 and the adjusting ring 301 have the same structure. The identical external structure makes the overall appearance of the device uniform after assembly.

[0033] The hydraulic accumulator 4 is movably installed on the outside of the electric energy storage device 101. The hydraulic accumulator 4 and the adjusting ring 301 are movably connected. The lower end of the hydraulic accumulator 4 is matched with the limiting hole 206. The movable connection between the hydraulic accumulator 4 and the adjusting ring 301 makes assembly and disassembly convenient. Therefore, the maintenance and replacement of the hydraulic accumulator 4 are also very convenient.

[0034] The threaded rod 204 and the threaded hole 304 are compatible, and the T-shaped rod 302 and the strip groove 202 are compatible. The compatibility between the T-shaped rod 302 and the strip groove 202 allows the adjusting ring 301 to move according to the installation of the hydraulic accumulator 4 without disengaging from the sleeve 201, thus saving the assembly time of the hydraulic accumulator 4.

[0035] Specific implementation process: This utility model is an electro-hydraulic direct drive transmission device that is easy to assemble. First, a protective sleeve 201 is installed in the middle of the outer end of the energy storage device 101 to protect the outer end of the energy storage device 101 from damage. At the same time, a T-shaped groove 202 is opened inside the sleeve 201. The outer end of the sleeve 201 is movably installed with an adjusting ring 301 through a T-shaped rod 302 that can move freely inside the groove 202. When the hydraulic accumulator 4 is in use, the lower end of the hydraulic accumulator 4 can be placed in the conical limiting hole 206. Then, by moving the T-shaped rod 302 up and down, the adjusting ring 301 is inserted from the upper end of the hydraulic accumulator 4. After insertion, the lower end of the T-shaped rod 302 is locked in the groove 202. Internally, the threaded rod 204 is operated. Through the connection structure of the threaded rod 204, it can extend into the interior of the strip groove 202. Then, the T-shaped rod 302 is fixed inside the strip groove 202 through the threaded hole 304. This structure not only facilitates the assembly of the hydraulic accumulator 4, but also improves the stability after assembly. The various components of this device complement each other. The setting of the adjusting ring 301 not only allows the hydraulic accumulator 4 to be assembled after being placed on the locking block 205, but also solves the cumbersome steps of fixing multiple components separately for the hydraulic accumulator 4. On this basis, the movable connection between the hydraulic accumulator 4 and the adjusting ring 301 facilitates assembly and disassembly, making the inspection and replacement of the hydraulic accumulator 4 extremely convenient.
