Description

Technical Field

[0001] This utility model belongs to the field of turbocharger technology, and in particular relates to an electronic control actuator mounting structure for a turbocharger. Background Technology

[0002] During the use of turbochargers, electronic actuators need to be stably installed on the turbocharger body to achieve precise control of the turbocharger's operating status. In the existing technology, the installation structure of the electronic actuator and the turbocharger body usually uses multiple sets of dispersed bolts to directly fix the electronic actuator housing to the turbocharger body shell. Under this installation method, during assembly, multiple bolt holes need to be aligned one by one and the bolts tightened one by one, which is a cumbersome operation. Moreover, when the electronic actuator needs to be maintained or replaced in the future, all bolts must be removed before the electronic actuator can be removed from the turbocharger body, which is also time-consuming and laborious.

[0003] A Chinese patent application with publication number CN119163499A discloses an electronic actuator for a turbocharger, including a housing assembly, a connecting rod assembly, a transmission assembly, a drive assembly, and an angle sensor assembly. The housing assembly has a mounting groove at its inner bottom end, which includes a circular segment, a connecting segment, and an extension segment that are connected together. The angle sensor assembly is installed in the mounting groove and extends from the circular segment to the extension segment. The connecting rod assembly includes an output shaft assembly, a deep groove ball bearing, a sealing assembly, a connecting rod, and an output pin. The bottom of the output shaft assembly is installed in the circular segment, and the top of the output shaft assembly passes through the deep groove ball bearing and extends out of the housing assembly for connection with the connecting rod.

[0004] While the mounting groove, incorporating circular, connecting, and extended sections, allows for the adaptation to various angle sensor assemblies, offering good versatility, and the output shaft assembly's top is interference-fitted with a deep groove ball bearing to reduce axial movement, thus minimizing wear and extending product lifespan, and the addition of a sealing component at the top of the output shaft assembly improves water resistance, this patent primarily focuses on the internal structure design of the electronic actuator. It provides limited description of the overall mounting structure of the electronic actuator and turbocharger, and lacks details on stabilizing and protecting the actuator through mechanisms such as pressing or squeezing mechanisms. Therefore, it falls short in terms of installation stability and actuator protection.

[0005] To address these issues, we provide an electronically controlled actuator mounting structure for a turbocharger. Utility Model Content

[0006] The purpose of this utility model is to provide an electronic control actuator installation structure for a turbocharger. By combining the squeezing mechanism and the pressing mechanism, it solves the problem in the existing electronic control actuator installation structure for turbochargers, where multiple sets of dispersed bolts need to be aligned and tightened one by one when assembling the electronic control actuator with the turbocharger body, and all bolts need to be removed during maintenance and disassembly, which leads to inconvenience in assembly and maintenance operations.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0008] This utility model relates to an electronically controlled actuator mounting structure for a turbocharger, comprising a mounting housing. A turbocharger is mounted on the front side of the mounting housing, and an electronically controlled actuator is mounted on the rear side of the mounting housing. Both sides of the electronically controlled actuator are provided with pressing mechanisms. The inner cavity of the mounting housing is provided with a pressing mechanism. The pressing mechanism includes two protective shells. The front side of each protective shell is fixedly connected to the mounting housing. Pressing rods are movably connected to the inner cavity of each protective shell. One side of each pressing rod passes through the protective shell and is fixedly connected to a pressing block. The other side of each pressing rod passes through the protective shell and is provided with a baffle. A power mechanism is provided at the top of each pressing rod.

[0009] The present invention is further configured such that the pressing mechanism includes a mounting plate, the front side of the mounting plate is fixedly connected to the mounting shell through a first reset spring, and a longitudinal clamping mechanism is provided on the left side of the inner cavity of the mounting shell. The mounting plate, as a supporting component, is elastically connected to the mounting shell through the first reset spring, so that the mounting shell has a reset function. The mounting shell, as a load-bearing structure, has a longitudinal clamping mechanism provided on the left side of its internal cavity for stable clamping in the vertical direction.

[0010] The present invention is further configured such that the longitudinal clamping mechanism includes a motor, the bottom of which is fixedly connected to the mounting housing, and a screw is fixedly connected to the output end of the top of the motor. Two clamping rods are threadedly connected to the surface of the screw, and a sliding rod is slidably connected to the right side of each clamping rod. The top and bottom of the sliding rod are fixedly connected to the mounting housing, and the bottom of the motor is fixed to the mounting housing. After startup, the top output end drives the screw to rotate. The screw surface engages with the two clamping rods through threads, converting the rotational motion of the screw into the lateral linear movement of the clamping rods. To ensure that the clamping rods move smoothly and do not rotate with the screw, the right side of the clamping rod is slidably connected to a fixed sliding rod, and the top and bottom of the sliding rod are fixed to the mounting housing, providing reliable guidance and support for the entire longitudinal clamping mechanism.

[0011] The present invention is further configured such that the power mechanism includes a rack, the bottom of which is fixedly connected to a pressing rod, and the top of which is meshed with a gear. A connecting rod is fixedly connected to the front side of the gear, passes through the protective shell, and is fixedly connected to a rotary valve. Locking mechanisms are provided on opposite sides of the gear. The bottom of the rack is fixed to the pressing rod to transmit power, and the top of the rack converts linear motion into rotational motion by meshing with the gear. A connecting rod is fixed to the front side of the gear, which passes through the protective shell and is connected to the external rotary valve, thereby realizing the control of the rotary valve. A locking mechanism is arranged on the other side of the gear, the function of which is to ensure that the gear can be reliably fixed when needed.

[0012] The present invention is further configured such that the locking mechanism includes an electric push rod, the top of which is fixedly connected to the protective shell, and a locking block is fixedly connected to the output end of the bottom of the electric push rod. When the electric push rod is started, the output end at its bottom drives the locking block to move linearly, so that the locking block can contact or separate from the target component according to the command, thereby realizing the mechanical locking or releasing function of the entire mechanism.

[0013] The present invention is further configured such that a second reset spring is provided on the opposite side of the baffle and is fixedly connected to the protective shell, a limit block is provided on the top of the baffle, and the second reset spring is provided on the opposite side of the baffle. The spring is fixedly connected to the protective shell and its function is to enable the baffle to automatically return to the initial position after being moved by force; at the same time, a limit block is provided on the top of the baffle to limit the range of movement of the baffle during the reset process and prevent it from being excessively displaced.

[0014] The present invention is further configured such that the top of the screw is movably connected to the mounting shell via a bearing, and an anti-slip pad is provided on the opposite side of the clamping rod. The top of the screw is movably connected to the mounting shell via a bearing. This structure ensures that the screw can remain stable during rotation and effectively reduces friction. At the same time, an anti-slip pad is provided on the opposite side of the two clamping rods, which increases the friction between the clamping surface and the workpiece, thereby preventing slippage during clamping.

[0015] The present invention has the following beneficial effects.

[0016] 1. This utility model ensures the reliability of the overall structure through the extrusion mechanism and the stable connection between the protective shell and the mounting shell. The flexible movement of the extrusion rod in the inner cavity of the protective shell drives the extrusion block to achieve a stable and efficient extrusion action. The baffle effectively prevents excessive displacement of the extrusion rod. The reasonable configuration of the power mechanism provides a continuous and balanced driving force for the extrusion process, enhancing its durability and ease of maintenance. It is suitable for various industrial application scenarios.

[0017] 2. This utility model effectively buffers the force during operation and achieves stable automatic reset by using the pressing mechanism and the connection of the first reset spring between the mounting plate and the mounting shell. At the same time, the longitudinal clamping mechanism set in the inner cavity of the mounting shell ensures the accurate positioning and reliable fixation of the object to be processed. The overall structure is compact and reasonable, which not only significantly improves the smoothness of operation and work efficiency, but also enhances the stability and service life of the mechanism under continuous use.

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Please see Figure 1-5This utility model is an electronically controlled actuator mounting structure for a turbocharger, including a mounting shell 1. A turbocharger 101 is mounted on the front side of the mounting shell 1, and an electronically controlled actuator 102 is mounted on the rear side of the mounting shell 1. A pressing mechanism 2 is mounted on both sides of the electronically controlled actuator 102. A pressing mechanism 3 is mounted inside the mounting shell 1. The pressing mechanism 2 includes two protective shells 21. The front side of the protective shell 21 is fixedly connected to the mounting shell 1. A pressing rod 22 is movably connected to the inner cavity of the protective shell 21. One side of the two pressing rods 22 passes through the protective shell 21 and is fixedly connected to a pressing block 23. The other side of the two pressing rods 22 passes through the protective shell 21 and is provided with a baffle 24. A power mechanism 25 is provided on the top of each pressing rod 22.

[0027] Specifically: the mounting shell 1 serves as the main structure to support and accommodate other components. The turbocharger 101 on its front side is responsible for increasing the intake pressure, while the electronically controlled actuator 102 on the rear side controls related actions via electrical signals. The extrusion mechanisms 2 on both sides of the electronically controlled actuator 102 and the pressing mechanism 3 inside the mounting shell 1 are all used to realize the mechanical extrusion function. Each extrusion mechanism 2 includes a protective shell 21 fixedly connected to the mounting shell 1 to provide protection. The movable extrusion rod 22 inside the protective shell 21 is used to transmit power. The extrusion block 23 connected to one side of the extrusion rod 22 directly performs the extrusion operation, while the baffle 24 on the other side is used to limit the range of movement. The power mechanism 25 at the top of the extrusion rod 22 provides the power source required for the entire extrusion process.

[0028] The pressing mechanism 3 includes a mounting plate 31. The front side of the mounting plate 31 is fixedly connected to the mounting shell 1 via a first return spring 32. A longitudinal clamping mechanism 321 is provided on the left side of the inner cavity of the mounting shell 1. The longitudinal clamping mechanism 321 includes a motor 322. The bottom of the motor 322 is fixedly connected to the mounting shell 1. A screw 323 is fixedly connected to the output end of the top of the motor 322. Two clamping rods 324 are threadedly connected to the surface of the screw 323. A sliding rod is slidably connected to the right side of the clamping rod 324. The top and bottom of the sliding rod are fixedly connected to the mounting shell 1. The power mechanism 25 includes a rack 251. The bottom of the rack 251 is fixedly connected to the pressing rod 22. Gear 252 is meshed with the top of 51. A connecting rod 253 is fixedly connected to the front side of gear 252 and passes through the protective shell 21 and is fixedly connected to a rotary valve 254. Locking mechanisms 4 are provided on opposite sides of gear 252. Locking mechanisms 4 include electric push rod 41. The top of electric push rod 41 is fixedly connected to the protective shell 21. A locking block 42 is fixedly connected to the output end of the bottom of electric push rod 41. A second return spring 5 is provided on the opposite side of baffle 24 and is fixedly connected to the protective shell 21. A limit block is provided on the top of baffle 24. The top of screw 323 is movably connected to mounting shell 1 through bearing. An anti-slip pad is provided on the opposite side of clamping rod 324.

[0029] Specifically: the mounting plate 31 is elastically connected to the mounting shell 1 via the first return spring 32 to achieve the reset function. The longitudinal clamping mechanism 321 located on the left side of the inner cavity of the mounting shell 1 is driven by a motor 322 (model JGA25-370 DC geared motor) to rotate the screw 323, causing the two clamping rods 324 to slide in opposite directions along the slide bar to achieve longitudinal clamping. The anti-slip pads on the inner side of the clamping rods 324 enhance the clamping stability. The power mechanism 25 drives the connecting rod through the meshing of the rack 251 and the gear 252. 253 and rotary valve 254 rotate to achieve power transmission; the locking mechanism 4 set on both sides of gear 252 drives the locking block 42 to move up and down through electric push rod 41, model FA-08-12-0005 series miniature electric push rod, to achieve locking or releasing function; the baffles 24 are connected to the protective shell 21 through the second return spring 5 to provide elastic return force, the limit block at the top of the baffle 24 is used to limit the range of movement, and the top of the screw 323 is movably connected to the mounting shell 1 through the bearing to ensure smooth rotation.

[0030] The working principle of this utility model is as follows: During operation, the electric actuator 102 is placed on the rear side of the mounting housing 1 and is stably installed through the pressing mechanisms 2 on both sides. When the rotary valve 254 is operated, the connecting rod 253 drives the gear 252 to rotate. The gear 252 meshes with the rack 251, causing the pressing rod 22 to move inside the protective housing 21, thereby driving the pressing block 23 to press the electric actuator 102 inward. The locking mechanism 4 pushes the locking block 42 through the electric push rod 41 to lock the position of the gear 252, ensuring that the pressing state remains stable. The baffle 24 is in the second... The return spring 5 causes the pressing rod 22 to automatically return to its original position when released. The pressing mechanism 3 inside the mounting housing 1 provides buffering and reset functions to the mounting plate 31 through the first return spring 32. The longitudinal clamping mechanism 321 is driven by the motor 322 to rotate the screw 323, which drives the two clamping rods 324 to move towards each other along the slide bar. The anti-slip pads on the inner side of the clamping rods 324 enhance the clamping force on the electric actuator 102, achieving longitudinal fixation. The entire mounting structure achieves rapid clamping and release through mechanical linkage, eliminating the need to disassemble and install bolts one by one, thus improving installation and maintenance efficiency.
