Description

Wearable smart devices and connector adapters

The present invention relates to an electrical connection method between the clothing-type I/O interface and the detachable device in a wearable smart device that at least includes a clothing-type I/O interface and a detachable device.

In addition, the present invention relates to a wearable smart device that at least includes a clothing-type input/output interface and a detachable device. The clothing-type input-output interface and the detachable device have different connection terminal shapes and/or terminal spacing for electrical purposes. A connector adapter that joins both physically and mechanically.

In recent years, technology that embeds sensing devices in clothing to measure biological signals or movements of people or animals has developed rapidly and can be widely used in fields such as sports, medical treatment, and health monitoring. These wearable electronic machines are called wearable smart devices.

The typical structure of a clothing-type wearable smart device is a combination of a clothing-type input/output interface with electrodes, sensing devices, wiring, connectors, etc., and a removable detachable device. The detachable device here is an electronic device that performs detection, measurement, calculation, memory, external communication, etc. of obtaining minute signals from electrodes or sensing devices.

Judging from the characteristics of wearable smart devices worn on the body, they must be as durable as ordinary clothes because they will be contaminated by biological substances or external dust. However, although electronic devices composed of conventional electronic circuits have some waterproof properties, they are not as high-quality as clothing materials. Water resistance or laundry durability that can withstand detergents and drying steps. As a result, the so-called realistic compromise method of removing the electronic device part during laundry is generally adopted. In addition, the same method is not limited to wearable smart devices, but is also applicable to products that combine fabric and electrical elements, such as carpet-type sheet heaters.

Although attempts have been made in the past to embed wiring components in clothes to provide electronic and electrical functions, most of them connected existing connectors to wiring embedded in the clothes. For example, audio pin sockets and USB terminals. Such a connector is easy to separate during use, and because of its relatively large size, it is easy to cause problems such as partial friction between clothes and skin due to the thickness of the connector, and problems of being easily hooked on the outside.

The spring hook type connector described in Patent Document 1 and Patent Document 2 can be said to be a method suitable for the process of making clothing, and can be used well when loading and unloading flexible fabrics. However, when used in the detachable device intended by the present invention, since most of the connecting parts on the device side are arranged on the rigid frame surface, only the clothes side is required to have a deformation function during attachment and detachment. As a result, an excessive force is applied to the mounting part of the spring hook. There is a problem that the electrical connection on the clothing-type input/output interface side is easily damaged.

In addition, in situations where subjects are vigorously moving, such as when measuring biological information in motion, since the mass of the detachable device has inertia, excessive force is continuously applied to the connector part on the clothing side, which may easily cause damage. The electrical contact of the connector part may become sparse, resulting in noise, or problems such as the detachable device falling off, especially during intense activities.

In addition, detachable devices with various functions have been developed in recent years. However, the connection part with the clothing-type input/output interface is not standardized and interchangeability cannot be ensured. Therefore, there is a disadvantage that when the detachable device is replaced, the clothing-type input/output interface side must also be replaced.

In addition, when the connection terminals on the clothing-type input/output interface are exposed, the connection terminals will be contaminated by dust, sebum, etc. from the environment, causing damage to the electrical connection. If the connection terminals are touched in a place with high potential, there is a risk of damage. Risk of electric shock to the dependent body through wiring laid on the interface.

The inventors of the present invention conducted intensive examinations to achieve the above purpose, and found that by making the mounting and detaching strength of the mating connector fall within a predetermined range, the detachable device in use does not fall off and the noise generated due to incomplete connection parts, etc. , and when the detachable device is detached, it will not impose excessive load on the clothing-type input and output interface side, so it is a wearable smart device that can be used for a long time.

In addition, the present inventors have completed an invention in which different detachable devices can be mounted on the same clothing-type I/O interface by improving the clothing-side I/O interface.

In addition, the inventors found that by improving the input/output interface on the clothing side, the contamination of the connection terminals can be reduced and the installability can be improved. Furthermore, by making the attachment and detachment strength of the mating connector fall within a predetermined range, it is no longer possible to use it. The detachable device falls off and noise is generated due to incomplete connection parts, and when the detachable device is disassembled It is a wearable smart device that can be used for a long time since it does not impose excessive load on the clothing-type input/output interface side.

In addition, the inventors of the present invention have completed the use of a connector adapter for electrically and mechanically joining the two when the connection terminal shapes and/or terminal intervals of the clothing-type input/output interface and the detachable device are different. An invention that allows detachable devices to be mounted on the same clothing-type input/output interface even if the shape and/or terminal spacing are different.

In the present invention, a pair of male member/female member fittings in which at least part of the contact surface is made of conductive material has the function of a so-called connector and has the functions of both electrical connection and mechanical connection. From the viewpoint of ease of attachment and detachment, the smaller the separation force of the male member/female member of the chimeric body, the better. On the other hand, in order to prevent the detachable device from being detached stably against vibration or acceleration associated with movement, a detachment force corresponding to a certain or greater mass of the detachable device is required.

(Hereinafter, an example in which the male member is arranged on the clothing side and the female member is arranged on the separable device side will be described. However, even if the male and female members are replaced, the same composition will be achieved, and this is within the scope of the present invention).

In addition, if the detachment force is set too high because an excessive priority is given to maintaining the stability of the detachable device, especially during detachment, the connection portion between the male member of the fitting body mounted on the clothing side and the electrical wiring material arranged on the clothing will be damaged. Or if excessive load is applied to the connection between the male component and the fabric itself that makes up the clothing, it is easy to cause electrical and mechanical damage.

Especially on the detachable device side, the structure is rigid and the female member of the fitting body is arranged in a casing on the same plane. It is necessary to elongate the clothing side to perform the detachment operation, and the detachment force is easily concentrated on one part of the fitting body. For this reason, special care needs to be taken against breakage.

If the disengagement force range of the chimeric body of the present invention is within the range, both the retention of the separable device and the prevention of damage in the event of disengagement can be achieved. In addition, in the present invention, particularly high effects can be obtained when the contact area between the fitting body and the clothing fabric or clothing side wiring meets predetermined conditions.

In addition, high results can be obtained when the quality of the separable device meets predetermined conditions.

As a result, the wearable smart device of the present invention has sufficient practical durability and can be effectively used to measure the biological information of drivers who are driving in vehicles such as cars with vibrations, and for athletes who are performing intense sports involving jumping. Biological information measurement, biological information measurement of mammals (domestic animals, pets) other than humans who sometimes exercise vigorously.

In addition, a second aspect of the present invention relates to a wearable smart device that uses at least a clothing-type input/output interface and a detachable device as components, and the number of electrical signal lines is a set of 2 lines. At this time, the connection between the clothing-type input/output interface and the detachable device requires a pair of electrical contacts. In the present invention, the pairs of electrical connection points are multiplied and each pair is consistent with the detachable devices having different specifications, so that detachable devices with different functions can be installed without exchanging the clothing-type input and output interface sides. And sometimes multiple detachable devices can be mounted at the same time.

The third aspect of the present invention relates to a wearable smart device that uses at least a clothing-type input/output interface and a detachable device as components, and the number of electrical signal lines is at least one set of 2 lines. At this time, the connection between the clothing-type input/output interface and the detachable device requires more than one pair of electrical contacts. The electrical contact may use a chimera such as a spring hook.

The chimera often exposes electrical contacts. In the present invention, by putting the electrical contact part into a bag with predetermined electrical insulation, the contamination of the electrical connection point due to environmental dirt, sebum, etc. can be reduced, and by putting the electrical terminals into the bag It has the effect of reducing the risk of unexpected electric shock.

Fourth aspect of the present invention

The present invention is a connector conversion joint, which is suitable for wearable smart devices that at least have a clothing-type input/output interface and a detachable device as components. In the combination of the clothing-type input/output interface with electrical connection terminals above the point, the electrical connection terminal spacing between the detachable device and the clothing-type input/output interface and/or the female and male of the fitting portion of the electrical connection terminal are electrically connected to the combined male member. It is used when it is inconsistent with the chimera of the female member.

By using fabric as the base material of the connector conversion joint, the present invention can convert the terminal shape and/or terminal spacing to make it suitable. At the same time, due to the softness of the base material, the clothing-type input/output interface and the detachable device can be easily installed and removed. , and especially easy to remove carefully when removing, thus extending the durability of the contact portion of the clothing-type input/output interface.

In addition, in the present invention, by using fabric as the base material of the joint, when the wearer of the wearable smart device exercises vigorously, the effect of absorbing and alleviating the vibration load through the joint can be obtained. As a result, the effects of both reducing the risk of the detachable device falling off and reducing the damage to the electrical connection portion on the clothing-type input/output interface side can be obtained.

In the fitting system of the present invention, at least a part of the contact surface is a fitting body of a male component/female component of conductive material. This fitting body has a function as a so-called connector and has functions of both electrical connection and mechanical connection.

The invention is a wearable smart device. The wearable smart device of the present invention is composed of a clothing-type input/output interface and a detachable device. The two are electrically and mechanically connected to function as a wearable smart device.

A wearable smart device is an electronic device attached to an attached body and is preferably an electronic device with at least one function selected from detection, memory, computing, communication, and display of signals containing information about the attached body, and/ Or an electronic device that can exert any electrical, physiological, or mechanical effects on the attached body.

The attached body is not particularly limited, but examples thereof include humans, animals (livestock, pets), and mechanical devices having at least mechanically movable parts.

In addition, wearable means literally wearing clothes, and further includes being directly or indirectly attached (patched), swallowed, or embedded on an attached body.

The clothing-type input/output interface of the present invention combines electrical elements into clothing (including outerwear, underwear, tops, pants, socks, gloves, hats, etc.) mainly made of fiber materials or parts that partially include fiber materials. Those with body accessories (helmets, shoes, protective clothing, protective gear). The electrical elements are not particularly limited, but may be electrical wiring used to transmit electrical signals or power, sensing functions used to collect information from the attached body of the clothing-type input/output interface, or used to collect information from the attached body and/or surroundings.

The mass of the separable device of the present invention is preferably between 2g and 80g, preferably between 3g and 70g, and more preferably between 5g and 50g. In most detachable devices, the power supply device occupies the largest mass. If the mass of the detachable device is reduced by more than necessary, the operating time will be shortened. In addition, when the mass of the detachable device exceeds a predetermined range, the inertia increases, so the risk of the attached body falling off during movement increases.

A second aspect of the present invention has a plurality of pairs of electrical contacts for connecting the clothing-type input/output interface and the detachable device. By aligning each pair with detachable devices having different specifications, it is possible to install detachable devices with different functions without exchanging the clothing-type input/output interface sides, and sometimes a plurality of detachable devices can be installed at the same time.

In the present invention, it is preferable to provide a plurality of pairs of electrical contacts preferably selected from pairs spaced at intervals of 20 mm ± 1 mm, pairs spaced apart at 38 mm ± 1 mm, and pairs spaced apart at 45 mm ± 1 mm. In addition, the distance here is the distance between the centers of the male or female components of each fitting body.

In the third aspect of the present invention, an electrical connection part is provided in the bag, and the bag is made of fabric having an insulation resistance of 1000Ω or more in the thickness direction. The insulation resistance here refers to the resistance value of the fabric after applying DC 500 volts for 1 minute between the center electrode (d1) and the counter electrode for volume resistivity measurement specified in 6.4.1.1 of IEC62899-201.

A fourth aspect of the present invention is a connector conversion joint used in the wearable smart device. The present invention is a combination of a detachable device with more than two electrical connection terminals and a clothing-type input/output interface with more than two electrical connection terminals. The electrical connection terminal spacing between the detachable device and the clothing-type input/output interface and/ Or a connector adapter used when the male and female of the mating part of the electrical connection terminal are inconsistent.

Examples of preferred electrical contact combinations in the present invention are as follows.

(1) A combination having at least one pair of fitting male members arranged at an interval of 20 mm ± 1 mm and a pair of fitting male members arranged at an interval of 45 mm ± 2 mm.

(2) A combination having at least one pair of chimeric female members arranged at an interval of 20 mm ± 1 mm and a pair of chimeric female members arranged at an interval of 45 mm ± 2 mm.

(3) In addition, the distance here is the distance between the centers of the male or female members of each fitting body.

In the fourth aspect of the present invention, the separation force between the male member and the female member of the fitting body is in the range of 0.15 N or more and 3.0 N or less. The detachment force is defined as the detachment force when the male member is stretched in a vertical direction relative to the joint surface of the female member. The lower limit of the separation force of the male member and the female member of the chimeric body of the present invention is preferably 0.2N or more, more preferably 0.30N or more, and still more preferably 0.42N or more. In addition, the upper limit of the detachment force is preferably 2.6N or less, more preferably 2.2N or less, and more preferably 1.8N or less.

In the present invention, the electrical connection between the clothing-type input/output interface and the aforementioned detachable device is carried out through a chimeric body composed of a pair of male and female members with at least part of the contact surface made of conductive material. Although the chimera has a side surface that simultaneously serves as a mechanical joint, a combination of mechanical joining methods other than the bonding of the chimera can also be used in the present invention.

In the present invention, one side of the male member or the female member of the fitting body is provided on the clothing-type input/output interface side, and the opposite side is provided on the separable device side. Generally, electrical connection requires at least two poles, so the number of chimeras in the present invention is preferably a plurality.

In many chimeric bodies, the yin and yang can be arranged uniformly on the clothing-type input/output interface side, or a combination of male and female components can be provided. This form is effective when it is necessary to determine the positive and negative electrical connections. In addition, chimeras of different sizes can also be used in combination.

The separation force of the fitting male member and the female member of the clothing-type input/output interface of the present invention is within the range of 0.3N or more and 10N or less. The detachment force is defined as the detachment force when the male member is stretched in a vertical direction relative to the joint surface of the female member. The lower limit of the separation force of the male member and the female member of the chimeric body of the present invention is preferably 0.40N or more, more preferably 0.50N or more, and more preferably 0.8N or more. In addition, the upper limit of the detachment force is preferably 8N or less, more preferably 7N or less, and more preferably 6N or less.

On the separable device side of the present invention, the male or female members of most chimeric bodies are preferably mounted on the same plane. Being on the same plane means that the contact surfaces of most of the male or female components of the chimera and the substrate are on the same plane. By being arranged on the same plane, when the attached body wearing the wearable smart device contacts or hits another object and exerts impact or large acceleration, the effect of preventing the detachable device from falling off is high.

The preferred contact area is more than 25 square mm, more preferably 37 square mm, and 60 square mm. Above is better, and above 80 square mm is even better. Although the contact surface is fully pressed when the contact pressure is sufficiently obtained, it is better to ensure sufficient electrical contact through conductive adhesive or the like. By using a soft conductor on the wiring material side, the crimping force can be improved.

The total area of the male member or the female member of the chimera installed on the clothes-type input/output interface side of the present invention and the cloth or wiring material on the clothes-type input/output interface side is preferably 30 square mm or more, and more than 50 square mm. It is better, and the contact area is preferably 75 square mm or more, 120 square mm or more is better, 160 square mm or more is better, and 200 square mm or more is even better.

The electrical wiring material of the clothing-type input/output interface and the connector conversion joint of the present invention is preferably a stretchable conductor composition.

The stretchable conductor composition of the present invention is composed of at least conductive particles (metal particles or carbon-based particles) and a flexible resin with a tensile elasticity of not less than 1 MPa and not more than 1000 MPa.
