Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of detection equipment, in particular to a wearable product static pressure detection device. BACKGROUND

[0002] For wearable products, such as clothes, trousers and other close-fitting garments, it is often necessary to detect their comfort, i.e. the pressure generated when they are worn on the corresponding group.

[0003] Chinese patent CN108562393A discloses a new anti-G suit pressurization abdominal, thigh and calf force measuring device, which comprises a sensor fixing unit and a force measuring unit. The sensor fixing unit realizes the universality and easy wearing of the present application. The thin film pressure sensor in the force measuring unit converts the measured garment pressure into pressure, and transmits it into the PC end control and storage display system in the form of electrical signal for real-time display and storage. The present application can be applied to study the relationship between the force, safety, comfort and operation efficiency of the pilot's abdominal and lower limbs under the anti-G suit pressurization, find the optimal force applying mode, ensure the safety of the pilot under the overload condition, and optimize the anti-G suit design to improve the comfort and operation efficiency of the pilot.

[0004] However, since the sensor of the above-mentioned patent is attached to the pilot's body through elastic material and magic tape, the pressure sensor is not directly attached to the pilot, and there is elastic cloth between the pilot and the pressure sensor. The pressure of the elastic cloth on the pilot will affect the pilot's feeling, and when it is applied to the comfort detection of daily clothing, the test will be biased due to the tightness of the individual wearing the fixing unit, so the above-mentioned patent cannot be applied to the comfort detection of daily clothing.

[0005] In summary, the prior art does not design a detection device suitable for testing the pressure of daily clothing, and cannot detect the comfort of wearable products. CONTENT OF THE INVENTION

[0006] In order to solve the problems existing in the prior art, the present disclosure aims to provide a wearable product static pressure detection device to solve the technical problem that the prior art cannot detect the comfort of wearable products.

[0007] The wearable product static pressure detection device disclosed by the present disclosure comprises a shell, an inflation assembly and a pressure detection assembly.

[0008] The inflation assembly includes an air pump, a first valve body, a main air pipe, and several branch air pipes, which are disposed within the housing. One end of the main air pipe is connected to the air pump, and the other end is connected to the several branch air pipes through the first valve body. A through hole adapted to the branch air pipe is provided on the outer side of the housing, and one end of the branch air pipe is connected to the pressure detection assembly through the through hole.

[0009] The pressure detection assembly includes an airbag, a connecting tube, and a pressure sensor. The airbag is connected to the connecting tube, one end of which is connected to the airbag and the other end of which is connected to the bronchus. The pressure sensor is disposed inside the airbag.

[0010] Preferably, the wearable product static pressure detection device further includes a cover, an opening at the top of the housing, the opening being adapted to the cover, and the cover being movably connected to the housing.

[0011] Preferably, the cover and the housing are detachably connected by screws.

[0013] Preferably, the wearable product static pressure detection device further includes an opening and closing assembly, the number of which is adapted to the number of the bronchus tubes. The opening and closing assembly includes a switch and a second valve body. The switch and the second valve body are connected. The second valve body is disposed inside the housing near the through hole and connected to the housing. One end of the second valve body is connected to the bronchus tubes, and the other end is connected to the pressure detection assembly.

[0014] Preferably, the wearable product static pressure detection device further includes a connector, the second valve body and the pressure detection component are connected through the connector, the connector is disposed on the outside of the housing near the through hole and connected to the housing.

[0019] The wearable product static pressure detection device disclosed herein has the following advantages:

[0020] The pressure detection component includes an air bladder, a connecting tube, and a pressure sensor. Instead of being fixed with elastic material, the pressure detection component is fixed with tape. The tape fixes the connecting tube in one place, thereby fixing the pressure detection component at the position to be tested.

[0021] Meanwhile, this disclosure, through the cooperation of the airbag and the pressure sensor, enables the pressure sensor to sense the change in air pressure inside the airbag after the airbag is inflated.

[0028] like Figures 1-3 As shown, a wearable product static pressure detection device disclosed herein includes a housing 1, an inflation component, and a pressure detection component;

[0029] The inflation assembly includes an air pump, a first valve body 3, a main air pipe 2 and several branch air pipes 4. The main air pipe 2 and several branch air pipes 4 are disposed inside the housing 1. One end of the main air pipe 2 is connected to the air pump, and the other end is connected to several branch air pipes 4 through the first valve body 3. A through hole adapted to the branch air pipes 4 is opened on the outer side of the housing 1. One end of the branch air pipe 4 is connected to the pressure detection assembly through the through hole.

[0030] The pressure detection assembly includes an airbag 5, a connecting tube 6, and a pressure sensor. The airbag 5 is connected to the connecting tube 6. One end of the connecting tube 6 is connected to the airbag 5, and the other end is connected to the bronchus 4. The pressure sensor is located inside the airbag 5.

[0031] Specifically, an extension pipe, a diverter pipe, or other auxiliary connecting pipe can be installed between the first valve body 3 and the branch pipe 4 to connect the first valve body 3 and the branch pipe 4. Optionally, the first valve body 3 can be a four-way valve.

[0032] The pressure detection component includes an airbag 5, a connecting tube 6, and a pressure sensor. The pressure detection component is not fixed with elastic material, but with tape. The tape fixes the connecting tube 6 in one place, thereby fixing the pressure detection component at the position to be tested.

[0033] Meanwhile, this disclosure, through the cooperation of airbag 5 and pressure sensor, enables the pressure sensor to sense the change in air pressure inside airbag 5 after airbag 5 is inflated, thereby enabling the pressure sensor to detect the pressure at any point within the coverage area of ​​airbag 5, transforming the pressure sensor's direct measurement of the pressure at a single point into the measurement of the pressure of a surface area of ​​airbag 5, thus expanding the measurement area of ​​the pressure sensor.

[0034] Furthermore, the wearable product static pressure detection device also includes a cover 7, a top opening of the housing 1, the cover 7 being adapted to the opening, and the cover 7 being movably connected to the housing 1.

[0035] Specifically, since the housing 1 is equipped with a main air pipe 2 and several branch air pipes 4, in order to facilitate the maintenance of the wearable product static pressure detection device described in this disclosure when a fault occurs, an opening is made at the top of the housing 1 and a suitable cover 7 is provided. The cover 7 covers the opening of the housing 1 to prevent dust and other contaminants from entering the interior of the housing 1. In order to facilitate maintenance, the cover 7 and the housing 1 are configured to be movably connected. The movable connection between the cover 7 and the housing 1 is illustrated by the following two embodiments.

[0036] Example 1

[0037] like Figure 2 As shown, the cover 7 and the housing 1 are detachably connected by screws.

[0038] Specifically, internally threaded cylinders are provided at the four corners of the opening, with the internal threads extending through the entire cylinder. Holes are also made at the bottom of the housing 1 at corresponding locations on the cylinders. The cylinders are fixedly connected to the housing 1, either by welding or by adhesive bonding.

[0039] Blind hole posts are provided at the four corners of the side of the cover 7 facing the opening. The blind holes correspond to the internal threads. When the cover 7 is locked to the housing 1 with bolts, the bolts pass through the internal threaded post from the opening at the bottom of the housing 1 and enter the blind hole post to complete the fixation.

[0040] Example 2

[0041] like Figure 3 As shown, the cover 7 and the housing 1 are rotatably connected by a hinge. The hinge is located inside one side of the housing 1 near the opening. At the top of the housing 1, opposite to the location of the hinge, there is a groove 8. The thickness of the groove 8 is adapted to the cover 7.

[0042] Specifically, the hinge is located inside one side of the housing 1, near the opening. The hinge is connected to the housing 1 and the cover 7 respectively. The hinge allows the housing 1 to rotate along the hinge axis, thereby achieving the effect of opening or closing.

[0043] To facilitate the opening of the cover 7 by staff, a groove 8 is provided on the top of the housing 1 at a location opposite to the hinge. Preferably, the thickness of the groove 8 is adapted to the thickness of the cover 7. The adaptation of the thickness of the groove 8 to the thickness of the cover 7 facilitates the opening of the cover 7 by staff.

[0044] Furthermore, the wearable product static pressure detection device also includes an opening and closing assembly. The number of opening and closing assemblies is adapted to the number of bronchus tubes 4. The opening and closing assembly includes a switch 9 and a second valve body. The switch 9 and the second valve body are connected. The second valve body is located inside the housing 1 near the through hole and is connected to the housing 1. One end of the second valve body is connected to the bronchus tube 4, and the other end is connected to the pressure detection assembly.

[0045] Specifically, in order to allow individual selection of the opening and closing of a bronchus 4, an opening and closing assembly is provided in a number adapted to the bronchus 4, including a switch 9 and a second valve body. The switch 9 and the second valve body are connected. The switch 9 is used to open or close the second valve body to realize the opening and closing of the bronchus 4. For example, the opening and closing of the second valve body is controlled by pressing the switch 9.

[0046] Furthermore, the wearable product static pressure detection device also includes a connector 10, through which the second valve body and the pressure detection component are connected. The connector 10 is located on the outside of the housing 1 near the through hole and is connected to the housing 1.

[0047] Furthermore, the wearable product static pressure detection device also includes a data transmission interface. The through hole is opened on one side of the outer side of the housing 1, and the data transmission interface is set on the outer side of the housing 1 corresponding to the through hole.

[0048] Furthermore, such as Figure 4 As shown, in order to control the inflation component and the pressure sensing component more quickly, the wearable product static pressure detection device also includes a controller 11, which is electrically connected to the inflation component and the pressure sensing component.

[0049] Specifically, the controller 11 can be a conventional controller such as a PLC (Programmable Logic Controller 11) or an MCU (Microcontroller 11), and the specific controller 11 can be selected according to the actual situation.

[0050] Furthermore, the wearable product static pressure detection device also includes a heat sink 12, which is disposed on the inner side of the housing 1 and connected to the housing 1; the housing 1 has a window at the location corresponding to the location of the heat sink 12.

[0051] Specifically, in order to prevent the inside of the housing 1 from overheating, a heat sink 12 is provided on the inner side of the housing 1. Optionally, the heat sink 12 can be a cooling fan. At the same time, the housing 1 has a window at the location corresponding to the location of the heat sink 12 so that the heat sink 12 can dissipate the heat inside the housing 1.

[0052] Furthermore, there are nine bronchi in the fourth bronchus.

[0053] The wearable product static pressure detection device described in this disclosure, when performing detection, such as Figure 5 As shown, the controller 11 is connected to a computer, which has the corresponding detection software installed. The pressure detection component is fixed at the position to be measured, and the measurement can be started by controlling the controller 11.

[0054] The wearable product static pressure detection device disclosed herein includes a pressure detection component comprising an airbag 5, a connecting tube 6, and a pressure sensor. The pressure detection component is not fixed by an elastic material, but by tape. The tape fixes the connecting tube 6 to one place, thereby fixing the pressure detection component to the position to be tested.

[0055] Meanwhile, this disclosure, through the cooperation of airbag 5 and pressure sensor, enables the pressure sensor to sense the change in air pressure inside airbag 5 after airbag 5 is inflated, thereby enabling the pressure sensor to detect the pressure at any point within the coverage area of ​​airbag 5, transforming the pressure sensor's direct measurement of the pressure at a single point into the measurement of the pressure of a surface area of ​​airbag 5, thus expanding the measurement area of ​​the pressure sensor.
