Description

Human Balance Ability Tester

technical field

The utility model relates to a human body balance ability tester, which can also be called a closed-eyed monopod tester.

Background technique

Standing on one foot with eyes closed is to measure the time for the human body to maintain the body's center of gravity on the support surface of one foot only by relying on the balance receptors of the vestibular organ of the brain and the coordinated movement of the muscles of the whole body without any visual reference. The strength of balance ability. The ability to stand on one foot with eyes closed is an important reflection of the physical fitness of middle-aged and elderly people.

Practicing standing on one leg every day can help prevent dementia. When standing on one foot, the body can effectively exercise the coordination of the brain in order to maintain balance, and can effectively exercise the pituitary gland and cerebellum, effectively preventing Alzheimer's disease.

Practicing standing on one leg every day can help develop your sense of balance. Especially when practicing standing on one foot with eyes closed, the body needs to fully mobilize the brain nerves to help maintain the balance of the body. Over time, the sense of balance of the body will become better and better. Don't insist on standing time when you practice for the first time, just keep practicing every day.

The existing one-leg standing test with eyes closed adopts a manual method. The tester observes the condition of the testee next to the testee, and uses a stopwatch to measure the time of standing on one leg with eyes closed. This method is not only greatly affected by human factors, but also affects the accuracy. And reliability, but also need to consume additional labor of the tester.

Utility model content

In order to solve the above-mentioned technical problems, the utility model provides a human body balance ability tester, which provides a hardware framework for obtaining standing person information, can output standing person information, and automatically tests single leg for use of relevant data processing systems Standing time provides the corresponding basis.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Fig. 1 and Fig. 2, the utility model provides a kind of human body balance ability tester, and this tester is used for testing people's balance ability, comprises base 20 and is positioned at the first test board 12 and the second test board above the base Two test boards 11, 13.

The surface of the base can be made of plastic or silicone material.

The first test board corresponds to the standing area of the leg to be tested, and its shape and size are adapted to the corresponding human foot standing area, so as to allow and facilitate one foot to stand on it, usually slightly larger than the actual occupied area of a single foot For the convenience of the person being tested, it can be significantly smaller than the area required for standing on both feet, so as to ensure that the tested single foot can stand on the relevant test board during the test and the other foot is not convenient to stand on the test board at the same time.

The second test board corresponds to the standing area of the other leg, and its shape and size are adapted to the corresponding human foot standing area to allow and facilitate one foot to stand on it, usually slightly larger than the actual occupancy of a single foot. The area is for the convenience of the person being tested, and it can be significantly smaller than the area required for standing on both feet, so as to ensure that the tested single foot can stand on the relevant test board during the test and the other foot is not convenient to stand on the test board at the same time .

The distribution intervals of the first test board and the second test board may be based on the corresponding areas of the feet of a person standing normally. In order to make the same tester suitable for the test of the left and right feet, the number of the first test board is usually one, which is arranged in the middle, and the number of the second test board is two, which are arranged on both sides of the first test board. One foot stands on the first test board, and the other foot can stand on the second test board on the corresponding side.

Also can only set a first test board and a second test board, and make two described test boards have the same position and function, test the single-leg standing time on any one test board, when only a first test board is set board and a second test board, and the two test boards are arranged side by side.

The two second test boards located on both sides of the first test board can be integrated or fixedly connected to each other, but for the convenience of manufacturing and use, the two second test boards are usually independent of each other.

A pressure signal collector or a human body induction signal collector of the first test board is arranged between the first test board and the base, and a second test board is arranged between the second test board and the base. Board pressure signal collector or human body induction signal collector, when one foot of a person is on the first test board (whether the other foot is lifted or standing elsewhere), the pressure of the first test board The signal collector or the human body induction signal collector obtains and outputs the corresponding standing person information (pressure signal or human body induction signal), when one foot of a person stands on the second test board, the second test board is The pressure signal collector or the human body induction signal collector obtains and outputs the corresponding station person information (pressure signal or human body induction signal).

A gap 14 is preferably left between the first test board and the second test board. For example, when the station person information collector is a pressure signal collector, the mutual influence between the first test board and the second test board can be avoided by setting a gap.

The pressure signal collector or the human body induction signal collector can adopt the existing technology. The pressure signal collector can use a pressure sensor or a switch element that triggers (switching switch state) under pressure; the human body induction signal collector can use an inductive human body induction signal collector, a capacitive human body induction signal collector, etc. collector or infrared human body induction signal collector, etc. The trigger pressure intensity or pressure judgment threshold of the pressure signal collector can be set according to the weight of the human body, because the test board (the first test board and the second test board are collectively referred to as the test board) is affected by the human body when standing on it. There is a big difference between the pressure and the pressure with no human feet standing on it. At present, the common corresponding components/devices can effectively distinguish the two situations; the human body induction signal collector should also be selected according to the corresponding test conditions in order to effectively distinguish In the two situations where someone's foot is on it or no one's foot is on it, the output when the foot is directly on it is different from the information output after the foot is lifted, and there is no confusion.

In the embodiment involved in Fig. 2, the station person information collector adopts a switch 51 with two contacts, one of which can be called a moving contact, and the other can be called a static contact. The heads are respectively connected to the top surface of the base and the bottom surface of the corresponding test board. The two contacts are arranged opposite to each other with a distance between them. When the two contacts touch each other, the switch is closed (conducted). When separated, the switch is off.

An example of the specific installation method of the two contacts: the moving contact is connected to the bottom of the corresponding test board, the static contact is connected to the top of the base and is located directly below the corresponding moving contact, and a gap is left between the two contacts. gap.

The test board may be supported on the base by support springs. When there is no person standing on the test board, the two contacts of the corresponding switch do not touch each other, and the switch is disconnected. When one foot of the person stands on the test board, the test board moves down under pressure, and the dynamic and static contacts of the corresponding switch interact with each other. Contact, the switch is closed, so the different state signals of the switch are used as the signal of the person standing, and it is judged whether the person is standing on the test board according to the on-off state of the switch. The two contacts or one contact of the switch can be set on the elastic contact (for example, a leaf spring, or a contact mounted on a coil spring), so that when the test board sinks differently due to different body weights , the switch can be turned on, and will not fail due to a small degree of sinking, nor will it be damaged due to a large degree of sinking.

Preferably, the support spring includes a helical spring 41, the lower end of the helical spring is connected to the top surface of the base, and the upper end is connected to the bottom surface of the corresponding test board, which can be directly connected or indirectly connected through a connecting piece. The number of the coil springs between each test board and the base is multiple, so as to realize the balanced support to the corresponding test board, ensure that the test board will not be excessively tilted during the actual test, and basically keep the parallel between the base and the base. state.

Further preferably, the supporting spring may also include or not include elastic pads 42, which may be columnar or generally called block-shaped, etc. When elastic pads are provided, each test plate will The number of elastic pads is also multiple, so as to achieve balanced support to the corresponding test board, the lower end of the elastic pad is fixedly installed on the base, and the upper end is located below the corresponding test board and connected to the test board. There is a gap between the boards, which can usually be the minimum or effective sinking distance for the corresponding test board to trigger the corresponding switch. The elastic coefficient of the elastic spacer can be greater than (usually significantly greater than) the elastic coefficient of the coil spring. When testing When the board is subjected to too much human body pressure, the test board sinks and triggers the corresponding switch and starts to contact the elastic pad, and the compressed elastic pad continues to sink. Avoid excessive sinking of the test plate without the buffering effect.

The relative positions among the switch, the substrate and the test board can be based on the existing technology, and the sinking distance of the test board can be controlled by selecting an appropriate support spring to meet the information collection (switch state switching) needs of the switch.

Similar to the above-mentioned principle, the station person information collector can adopt any switch that can control the state of the switch by moving up and down the test board, such as a micro switch, a position switch, a key switch, a push button switch, and a proximity switch. A fixed part, such as a switch housing or a switch seat) is installed on one of the base plate and the test board, and the operating head or the sensing surface of the switch faces the other of the base plate and the test board, and is fixedly connected with the other (proximity switch except) or with a gap between said other, when a person's foot stands on the test board, the test board sinks causing the switch to turn from open to closed. In this case, the setting method of the test board and the base (including the support spring) can be the same as or similar to the above-mentioned case where the station information collector adopts a switch with two contacts, or it can be determined according to the specific station information collector. The requirements are designed separately.

When the station person information collector adopts a pressure sensor, a human body induction information collector or other forms of switches, the relevant test board and base can be determined according to the specific requirements of the pressure sensor, human body induction information collector or switch used The positional relationship and connection mode between them determine the connection mode of the pressure sensor, human body sensing information collector or switch. The panel of the collector is used as a corresponding detection board, and the human body sensing information collector is fixedly installed on the base or fixedly installed on the installation panel at the top of the base.

The base can be provided with a surrounding frame 21.

The top surface is flush with the top surface of the installation panel (in the same plane) or slightly higher than the top surface of the installation panel.

When the test board is movably connected to the installation panel, the installation panel may be provided with holes corresponding to each of the test boards, and a support spring is provided between each of the test boards and the base, The test board is supported by corresponding supporting springs, and there is a gap between the periphery of the test board and the wall of the corresponding hole of the installation panel to allow the test board to move up and down under the restriction of the corresponding hole, normally Next, the top surface of the test board is flush with the top surface of the installation panel (in the same plane) or slightly higher than the top surface of the installation panel.

A surface layer or no surface layer 60 may be provided on the installation panel. The surface layer can usually be made of sheet material with certain flexibility to cover each of the test boards, and its edges are fixedly connected with the frame and/or the installation panel, and are preferably sealed to each other by bonding or pressing. , through the setting of the surface layer, the experience of the testee can be improved, and it is helpful for the appearance and the protection of the internal device.

The installation panel or the frame may or may not be provided with a power switch 31, which is used as a power switch of the tester.

Said installation panel can be provided with or not be provided with indicator light 33, and described indicator light can comprise power supply indicator light and work indicator light, is used as the power supply indication and working state indication of this tester, can also comprise other indicator lights .

The installation panel or the frame may or may not be provided with an I/O interface 52, and the I/O interface may be in any desired form, and the number may be one or more, for example, in various forms The signal line socket, USB socket, etc., are used for data transmission with external devices.

The installation panel or the frame may or may not be provided with a power interface, for example, various types of sockets for plugging in an external power supply.
