Description

Technical Field

[0001] This utility model relates to the field of rehabilitation robot technology, specifically to a centrally controlled solenoid valve assembly. Background Technology

[0002] Stroke, also known as brain apoplexy, is one of the leading causes of disability worldwide. Patients often experience motor dysfunction such as hemiplegia. Traditional rehabilitation relies on physical therapists, but this approach suffers from high labor costs and insufficient training intensity. To address these issues, rehabilitation robots primarily guide patients through hand and foot exercises, gradually restoring nerve, joint, and muscle function. Among the many existing rehabilitation robots, pneumatic soft rehabilitation robots are gaining increasing attention due to their lightweight design. Solenoid valve assemblies are crucial components of pneumatic soft robots, controlling the gas flow rate and runtime of the drive unit, thereby controlling the bending or straightening of the drive unit and synchronizing the patient's body movements. However, existing solenoid valve assemblies have a drawback: when too many valve connections are used during operation, uneven interface wires can cause detachment, and assembly becomes overly cumbersome, hindering production.

[0003] Therefore, there is a need in the field for a centralized control solenoid valve assembly structure that can effectively avoid cumbersome assembly and prevent wire breakage. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects of the existing technology and provide a centrally controlled solenoid valve assembly.

The straight connectors are installed in the air pipe interface holes. The top side walls of the first air passage, the second air passage, and the air pipe interface holes are all provided with through holes. Each solenoid valve has three air ports, which are respectively connected to one through hole located in the first air passage, the second air passage, and the air pipe interface hole. The air pipe interface hole is connected to only one of the air passages through the solenoid valve.

Detailed Implementation

[0032] Unless otherwise defined, the technical or scientific terms used in this specification and claims shall have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains. All values ​​listed herein, ranging from the minimum to the maximum, refer to all values ​​obtained by incrementing the minimum and maximum values ​​by one unit when the difference between the minimum and maximum values ​​is more than two units.

[0033] The following describes specific embodiments of this utility model. It should be noted that, in order to provide a concise description, this specification cannot provide a detailed description of all features of the actual embodiments. Without departing from the spirit and scope of this utility model, those skilled in the art can modify and substitute the embodiments of this utility model, and the resulting embodiments are also within the protection scope of this utility model.

[0034] Traditional solenoid valve assemblies suffer from drawbacks such as uneven interface wires leading to detachment when too many valves are connected during operation, and excessive assembly during equipment assembly, which is detrimental to production. The purpose of this application is to provide a centrally controlled solenoid valve assembly.

[0035] In one specific embodiment, this application provides a centralized control solenoid valve assembly. This assembly connects multiple interface lines of solenoid valves to an adapter plate, allowing for easy insertion and removal of the solenoid valve interface lines for secure mounting to the equipment frame. The centralized control solenoid valve assembly includes an adapter plate, an adapter socket, and multiple solenoid valves. The adapter socket is fixed to the adapter plate, the adapter plate is fixed to the solenoid valves, and the solenoid valves are connected to the equipment frame. In this application, the adapter socket is fixed to the adapter plate by soldering, and the adapter plate is also fixed to the solenoid valves by soldering. Both connections are rigid connections, facilitating assembly and production.

[0036] In one specific embodiment, the centralized control solenoid valve group includes a horizontal adapter plate, an adapter socket, and a 7-way solenoid valve. The adapter socket is located on the adapter plate at the center of the horizontal position. The adapter plate and the adapter socket are integrated on the solenoid valve. The solenoid valve is fixedly installed inside the equipment frame. The solenoid valves are arranged in an L-shape to form a 7-way solenoid valve group. The 7-way solenoid valve group is located above the solenoid valve seat and is fixedly connected through corresponding holes.

[0037] In one specific embodiment, the adapter plate is in the shape of a flat frame or a flat rounded corner, with holes on its surface for fixed connection with the solenoid valve. At the same time, the adapter plate needs to be parallel to the plane of the solenoid valve to avoid tilting during installation and bending due to pressure. A certain distance is left between the plane formed by the adapter plate and the solenoid valve to prevent damage to the solenoid valve during soldering.

[0038] In one specific embodiment, the solenoid valve seat needs to be fixedly connected to the corresponding hole of the equipment frame, and the solenoid valve seat also needs to leave a corresponding gap between itself and the side wall of the equipment frame to provide a position for the installation of the L-shaped threaded two-way valve (used to install the air pressure sensor).

[0039] In one specific embodiment, the solenoid valve seat connection to the drive component includes multiple straight connectors. The straight connectors need to have holes opened at positions corresponding to the solenoid valve seat to connect to the air tube of the rehabilitation glove, while maintaining a seal to prevent air leakage during equipment operation.

[0040] In one specific implementation, the adapter board is equipped with multiple positive and negative signal input interfaces through circuit design. The signals received from the adapter socket are processed and output to the multiple positive and negative input interfaces to control the solenoid valve.

[0041] In one specific implementation, the solenoid valves need to be arranged neatly to facilitate the installation of the adapter plate.

[0042] In one specific implementation, the adapter board contains a PCB board with internal control circuitry for signal transmission. Example

[0043] The embodiments of this utility model will be described in detail below. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the following embodiments. Example 1

[0044] A type of centrally controlled solenoid valve assembly, the structure of which is as follows: Figure 1 As shown, it includes a solenoid valve seat 2, seven solenoid valves 3 mounted on top of the solenoid valve seat 2, an adapter plate 1 mounted on top of the solenoid valves 3, and seven straight connectors 5 mounted on the side of the solenoid valve seat 2, as detailed below.

[0045] The structure of the solenoid valve seat 2 is as follows Figure 3 As shown, the solenoid valve seat 2 has a first air passage 21 and a second air passage 22. One end of the first air passage 21 is closed, and the other end, through an L-shaped threaded two-way pipe 4, is fitted with a pressure sensor and is also closed. One end of the second air passage 22 is open to the atmosphere, and the other end is closed. The side of the solenoid valve seat 2 has seven air pipe interface holes 25, and a straight connector 5 is installed in each air pipe interface hole 25. The top of the solenoid valve seat 2 also has seven sets of through holes 23 and seven sets of mounting holes 24. Each set of through holes 23 includes three holes, which are respectively connected to the first air passage 21, the second air passage 22, and the air pipe interface hole 25. Each set of mounting holes 24 includes two holes for fixing and installing the solenoid valve 3.

[0046] The structure of solenoid valve 3 is as follows Figure 4As shown, it is L-shaped, with two pin rows 31 at the top and three air tubes (not shown in the figure) at the bottom, which are inserted into the same group of through holes 23.

[0047] The structure of adapter plate 1 is as follows Figure 2 As shown, an adapter socket 11 is soldered to its top. The outer shell of the adapter socket 11 has a slot 12, and the inside has pins. The adapter board 1 contains a PCB board with control circuitry. The adapter board 1 also has 7 pairs of soldering holes 13, each pair of soldering holes 13 including 2 pins. During installation, the pins 31 on the solenoid valve 3 pass through a pair of soldering holes 13 and are then connected to the control circuitry by soldering. Therefore, the control signal reaches the control circuitry on the PCB board through the pins, and then controls the operation of the solenoid valve 3. This is prior art and will not be described in detail in this application.

[0048] The structure of the straight-through head 5 is as follows Figure 5 As shown, in this embodiment, there are seven straight-through heads 5, namely, a first straight-through head 51, a second straight-through head 52, a third straight-through head 53, a fourth straight-through head 54, a fifth straight-through head 55, a sixth straight-through head 56, and a seventh straight-through head 57. The outer ends of the first to fifth straight-through heads 51 are connected to the five finger actuators of the rehabilitation glove. The outer end of the sixth straight-through head 56 is connected to the air outlet of the one-way pump, and the outer end of the seventh straight-through head 57 is connected to the air inlet of the one-way pump. Figure 7 As shown.

[0049] The working principle of the three sets of solenoid valves is as follows, taking the finger actuator connected to the first through head 51 as an example.

[0050] When the finger actuator requires positive pressure, i.e., when it needs to be inflated, the x and z ports of the third solenoid valve seat 34 open, and the y port closes; the o and m ports of the second solenoid valve seat 33 open, and the n port closes; the c and b ports of the first solenoid valve seat 32 open, and the a port closes. At this time, the air travels through the following path: Atmosphere → Second air passage 22 → x port → z port → Seventh straight connector 57 → One-way pump inlet → One-way pump outlet → Sixth straight connector 56 → o port → m port → First air passage 21 → c port → b port → First straight connector 51 → Finger actuator, thus achieving inflation and pressurization.

[0051] When the finger actuator requires negative pressure, i.e., when the gas inside the finger actuator needs to be extracted, ports b and c of the first solenoid valve seat 32 open, and port a closes; ports y and z of the third solenoid valve seat 34 open, and port x closes; ports o and n of the second solenoid valve seat 33 open, and port m closes. At this time, the air travels through the following path: finger actuator → first straight connector 51 → port b → port c → first air passage 21 → port y → port z → seventh straight connector 57 → one-way pump inlet → one-way pump outlet → sixth straight connector 56 → port o → port n; seventh straight connector 57 → one-way pump inlet → one-way pump outlet → sixth straight connector 56 → port o → second air passage 22; seventh straight connector 57 → one-way pump inlet → one-way pump outlet → sixth straight connector 56 → port o → atmosphere, thus achieving air extraction and pressure reduction. Example 2

[0052] It adopts a structure similar to that of Embodiment 1, but in this embodiment, there are only 5 straight-through heads 5 and 5 solenoid valves 3, such as Figure 8 As shown. In this embodiment, one end of the first air passage 21 in the solenoid valve seat 2 is open and connected to an air pump, while the other end is fitted with an air pressure sensor via an L-shaped threaded two-way pipe 4. At this time, this end is in a closed state. One end of the second air passage 22 is open and connected to a vacuum pump, while the other end is closed.

[0053] In this embodiment, the gas path connection is as follows: Figure 9 As shown, the principle is as follows.

[0054] When the finger actuator needs positive pressure, the air pump is started, the d and e ports of the solenoid valve 3 are opened, and the f port is closed. At this time, the gas directly enters the finger actuator through the first air passage 21, the solenoid valve 3, and the straight-through head 5 to achieve inflation and pressurization.

[0055] When the finger actuator requires negative pressure, the vacuum pump is activated, ports d and f are opened, and port e is closed. At this time, the gas passes through the straight-through head 5, solenoid valve 3, second air passage 22, and vacuum pump in sequence, and is then discharged into the atmosphere, thus achieving vacuuming and pressure reduction.

[0056] The above description of the embodiments is intended to enable those skilled in the art to understand and apply this application. It will be apparent to those skilled in the art that various modifications can be easily made to these embodiments, and the general principles described herein can be applied to other embodiments without creative effort. Therefore, this application is not limited to the embodiments described herein, and any improvements and modifications made by those skilled in the art based on the disclosure of this application without departing from the scope and spirit of this application are within the scope of this application.
